                SUBJECT TO COMPLETION -- DATED DECEMBER 23, 1996
PROSPECTUS 

                             IAT MULTIMEDIA, INC. 
              3,100,000 Units consisting of 3,100,000 shares of 
                     Common Stock and 3,100,000 Warrants 

   Each unit ("Unit") offered by IAT Multimedia, Inc., a Delaware corporation 
(the "Company"), consists of one share of common stock, par value $.01 per 
share (the "Common Stock"), and one redeemable warrant (the "Warrants"). The 
components of the Units will not be transferable separately until      , 1997 
or such earlier date (the "Separation Date") as Royce Investment Group, Inc. 
shall determine. Each Warrant entitles the holder to purchase one share of 
Common Stock at an exercise price of $7.80, subject to adjustment, at any 
time from the Separation Date until the fifth anniversary of the date of this 
Prospectus. Commencing 15 months from the date of this Prospectus, the 
Warrants are subject to redemption by the Company at a redemption price of 
$.05 per Warrant on 30 day's written notice, provided the closing bid price 
of the Common Stock equals or exceeds $16.00, subject to adjustment, for 20 
consecutive trading days ending within five days of the notice of redemption. 
See "Description of Securities." 

   Prior to this Offering, there has been no public market for the Units, the 
Common Stock or the Warrants and there can be no assurance that such a market 
will develop. The Company has applied for quotation of the Units, the Common 
Stock and the Warrants on the Nasdaq National Market ("Nasdaq") under the 
symbols    ,     and    , respectively. It is anticipated that the initial 
public offering price will be between $5.50 and $6.50 per Unit. See 
"Underwriting" for a discussion of factors considered in determining the 
initial public offering price. 
                                    ------ 
   The securities offered hereby involve a high degree of risk and immediate 
substantial dilution. See "Risk Factors," which begin on page 11, and 
"Dilution." 
                                    ------ 
          THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE
           SECURITIES AND EXCHANGE COMMISSION OR ANY STATE SECURITIES
            COMMISSION NOR HAS THE SECURITIES AND EXCHANGE COMMISSION

   The Company intends to furnish its stockholders with annual reports 
containing financial statements audited by its independent certified public 
accountants. 
                                    ------ 

   IN CONNECTION WITH THIS OFFERING, THE UNDERWRITER MAY OVER-ALLOT OR EFFECT 
TRANSACTIONS WHICH STABILIZE THE MARKET PRICE OF THE UNITS, COMMON STOCK 
AND/OR WARRANTS AT A LEVEL ABOVE THAT WHICH MIGHT OTHERWISE PREVAIL IN THE 
OPEN MARKET. SUCH STABILIZING, IF COMMENCED, MAY BE DISCONTINUED AT ANY TIME. 
<PAGE>


   The Company is organized under the laws of the State of Delaware. 
Investors in the Units will be able to effect service of process in the 
United States upon the Company and may be able to effect service of process 
upon its directors. However, the Company is primarily a holding company which 
holds stock in entities in Switzerland and Germany and all or a substantial 
portion of the assets of the Company are located outside the United States. 
In addition, all of the Company's four directors and all of its executive 
officers are residents of foreign countries and all or a substantial portion 
of the assets of such directors and officers are located outside of the 
United States. As a result, it may not be possible for investors to enforce 
judgments of U.S. courts predicated upon the civil liability provisions of 
U.S. laws against the Company's, the foreign directors' and officers' assets. 

   The Company has been advised by its counsel, Baker & McKenzie, that there 
is doubt as to the enforceability in Switzerland of judgments of U.S. courts, 
against Multimedia's subsidiaries and against shareholders, directors, 
officers and employees of Multimedia or its subsidiaries who are domiciled in 
Switzerland. In addition, awards of punitive damages in actions brought in 
the United States or elsewhere may be unenforceable in Switzerland. 

   The Company has been advised by its counsel, Dr. Schackow & Partner, that 
there is doubt as to the enforceability in Germany in original actions or in 
actions for enforcement of judgments of U.S. courts, of civil liabilities 
predicated solely upon the laws of the United States against Multimedia's 
subsidiaries and against shareholders, directors, officers and employees of 
Multimedia or its subsidiaries who are domiciled in Germany. In addition, 
awards of punitive damages in actions brought in the United States or 
elsewhere may be unenforceable in Germany.

   Amounts and percentages appearing in this Prospectus may not total due to 
rounding. 
                                    ------ 

   Prospective investors are cautioned that the statements in this Prospectus 
that are not historical facts may be "forward-looking statements" that are 
subject to risks and uncertainties. Such forward-looking statements, include 
statements regarding, among other items, the Company's growth strategy, 
future products, sales, ability to market products and anticipated trends in 
the Company's business. These forward-looking statements are based largely on 
the Company's expectations and are subject to a number of risks and 
uncertainties, certain of which are beyond the Company's control. Actual 
results could differ materially from these forward-looking statements as a 
result of a number of factors including, but not limited to, the Company's 
ability to successfully complete the development of its third generation 
products, the ability to achieve market penetration, the need for additional 
financing, intense competition in various aspects of its business, the 
Company's ability to expand into the United States, its dependence on key 
personnel, and other factors described in the Risk Factors section and 
elsewhere herein.

                                 THE COMPANY 

   The Company develops, manufactures and markets customizable high quality 
visual communications systems for use in desktop computers which permit users 
to hold multi-point video conferences in two or more locations, as well as 
providing additional video, audio and data transfer features not available in 
traditional video conferencing systems. Unlike traditional video conferencing 
companies, the Company's focus is on high quality system solutions. The 
Company believes that the needs of its target customers cannot be addressed 
by currently available lower quality software-only products (including 
Internet products) or by high quality traditional video conferencing 
products. In addition to providing audio and video images of the other 
participants in the tele-conference, the Company's systems are also capable 
of simultaneously providing images and data in windows on the computer screen 
which can be viewed by all participants in the video conference and permit 
users at remote computer terminals to modify data and manipulate images 
through the operation of apparatus, such as microscopes and video cameras. 
These systems, which include both proprietary and third-party software and 
hardware, are inter-operable with products from certain vendors and comply 
with all relevant international standards, including H.320. The Company sells 
its systems and kits to end-users in a variety of industries and to OEMs and 
integrators. The Company has sold an aggregate of approximately 500 systems 
and kits, including pilot projects, since 1990. 

   The Company's technology has been developed with companies which the Company
based on various agreements, considers to be its strategic partners ("Strategic
Partners"), including Deutsche Telekom ("DT"), Texas Instruments ("Texas
Instruments"), IBM Deutschland Informationssysteme GmbH ("IBM Germany") and
Olympus Optical Co. (Europe) GmbH ("Olympus"). The Company believes that its
technology can produce substantially higher quality image and video
transmissions, including reduced noise and artifacts, truer color representation
and higher frame rates, than other systems while using less of the computing
power of the host desktop computer, which permits other applications to continue
to operate without interruption. In addition, the Company's new generation of
systems currently being developed is based on a programmable digital signal
processor which provides flexibility for adapting to new algorithms, standards
or user requirements. The Company believes that the high image quality and other
features provided by the Company's systems will meet the requirements of various
professional users including tele-medicine (i.e., transferring microscope,
x-ray, video or other diagnostic images for evaluation by a physician at a
remote site) and tele-surveillance (i.e., remote viewing and control of
surveillance cameras and remote access control). In excess of $22 million was
invested in the Company by its stockholders and the Company has invested
approximately $13 million in the research, development and marketing of its
technology (including approximately $4 million in participations from the
Company's Strategic Partners). This investment does not include additional
amounts invested directly by the Company's Strategic Partners in the development
of their components used in the Company's systems.

   The Company believes that the multimedia communications market will be
divided between mass- market low quality software-only solutions and high
quality system solutions which principally utilize hardwired processors. The
Company believes that mass market solutions do not meet the needs of its
potential customers because of the lower quality image and video transmissions
and that hardwired processors are inflexible and difficult to adapt to new
algorithms and standards. In addition, the Company believes that its use of
programmable digital signal processors combined with its proprietary
technology offers a competitive advantage over competitors using hardwired
chips or software-only solutions. The Company is not aware of other companies
which offer similar customized complete systems at comparable prices.


   The Company has developed two generations and is currently developing a third
generation of its technology. The first generation was developed using a large
number of computer boards and readily available components as the Company's
initial entry in the visual communications field and to assess customer needs.
The second generation, utilized in the Company's current systems, is
characterized by a substantially reduced number of computer boards and improved
capabilities. These systems use a combination of fully programmable digital
signal processors and less-flexible hardwired processors. The second generation
systems have inherently high prices per unit. For example, the Company's second
generation MFKS Vision and Live multifunctional communications systems ("MFKS")
have average prices of approximately $8,000 to $30,000 per system (depending on
capabilities). Third generation systems, which the Company expects to begin
shipping in 1997, utilize Texas Instruments' TMS320C80 programmable digital
signal processor (the "C8x") and are designed for commercial production with
target sales prices of approximately $1,500 to $8,000 per system for
corresponding MFKS systems. The Company believes that its third generation of
systems will be its first systems which have the potential for widespread
commercialization.

   The Company's existing products include the MFKS Vision and Live multi-
functional communications system and the MIKS Interactive Kiosk ("MIKS"). 
MFKS is a high quality visual communications system which combines hardware 
and software for use in desktop computers and permits users to hold 
multi-point video conferences with simultaneous video, audio and data 
transfer. MIKS is an electronic kiosk system which allows consumers to access 
information stored in the electronic kiosk or in remote locations, including 
high quality video, while allowing instant contact to a video conference with 
a tele-consultant who has full access to the images and data seen by the 
consumer. 

   The Company developed its MFKS systems jointly with DT. The Company offers 
MFKS 128 systems which include software, two computer boards and two optional 
computer boards and MFKS 384 systems which include six to nine computer 
boards. These systems permit tele-conferencing and simultaneous full screen 
video with a second smaller video window ("PIP"), audio and data 
communications on a desktop computer and, in the case of MFKS 384 systems, 
the ability to view two full-screen video windows simultaneously. The Company 
believes that the combination of the tele-conference and additional functions 
performed by its MFKS systems provide features required by professional users 
and not generally available in existing tele-conferencing systems. MFKS 
systems are currently used by DT for administrative tasks; by customers of 
DeTeSystems, an integrator and affiliate of DT, for a variety of tasks in 
different industries; by MAN Roland for tele-servicing of large, high-speed 
printing presses; by Grundig for tele-surveillance in an underground subway 
system; by the water quality control industry for visual water testing from 
remote sites; and by hospitals for pilot projects in tele-microscopy and 
tele-endoscopy. 

   The Company is jointly developing base hardware and software with Texas
Instruments and DT for its third generation MFKS system incorporating the C8x
which will allow for easier upgrades than systems using hardwired chips. These
new systems will provide all of the functions of the corresponding existing
second generation systems at substantially lower target prices. The third
generation MFKS 128 uses a single proprietary computer board while the third
generation MFKS 384 system only requires three computer boards. The Company
expects to release the third generation of MFKS systems in 1997 jointly with its
Strategic Partners. In addition to complete systems, the Company offers MFKS
kits utilizing its existing second generation technology to OEMs and integrators
and expects to begin offering kits utilizing its third generation technology in
1997. No assurance can be given that such systems or kits will be introduced on
a timely basis, if at all, or that such systems will be accepted by the market.

   The Company is presently working with Olympus to integrate MFKS systems 
into tele-microscopes. These products are expected to allow physicians in 
different locations to engage in a video conference while concurrently 
reviewing microscopic slides, and in some models, to remotely operate the 
microscope. The Company does not believe that the images from current visual 
communications systems provide sufficient image quality to transmit pictures 
of microscopic slides which would permit their use for diagnosis. The Company 
believes that the high quality images produced by the MFKS system offer 
images with resolutions and life-like colors sufficient for medical 
diagnoses. 

   In addition, the Company is jointly developing with the Technical 
University of Berlin proprietary wavelet data compression technology, which 
the Company believes will almost eliminate the time delay in viewing still 
images which are transmitted by visual communications systems and that this 
reduction will make the Company's MFKS systems more attractive. The Company 
believes that it will be able to offer wavelet compression in its MFKS 
systems beginning in 1997 and that one of the first applications for this 
technology will be in the tele-microscopes being jointly developed with 
Olympus. 

   MIKS was jointly developed with DT and IBM Germany. MIKS consists of consumer
electronic kiosks, tele-consultant stations, an authoring system, a proprietary
database management system and related proprietary software. The Company
believes MIKS systems can enable companies to more efficiently utilize their
personnel and to rapidly collect market information on consumers using the
electronic kiosks. The authoring system reduces the cost and time to develop
menus and pages for electronic kiosk displays. The Company's proprietary
database management system allows rapid and accurate updating of information
stored in the electronic kiosks and collection of consumer data. The Company's
second generation MIKS system requires two desktop computers per electronic
kiosk and has an average price of approximately $45,000 per electronic
kiosk. To date, the Company has only installed pilot MIKS systems. The Company,
IBM and DT are jointly developing the third generation MIKS systems which will
reduce the hardware demands to only one desktop computer with two proprietary
computer boards per electronic kiosk. The Company has a target price for the
third generation MIKS system is approximately $20,000 per electronic kiosk and
expects to begin selling third generation MIKS systems in 1997. No assurance can
be given that such systems will be introduced on a timely basis, if at all, or
that such systems will be accepted by the market.

   The Company's systems are flexible and can be configured in a variety of
ways to meet the requirements of specific customers. The Company, on a project
by project basis, designs systems which provide solutions on a customized
basis for the specific requirements of particular customers.

   The Company currently markets its products, both through its own sales staff
and through certain of its Strategic Partners, primarily in Europe. A
substantial part of the potential market for the Company's products are in the
United States and entering into the United States market is a fundamental part
of the Company's strategy. The Company intends to expand its marketing efforts,
both by expanding its sales and marketing staff in Europe as well as
establishing an office and a sales and marketing staff in the United States
during 1997. The Company continually evaluates potential strategic partners for
additional applications and broader marketing of IAT's technology. The Company
may make a participation or acquisition for strategic reasons.

   The Company was incorporated in Delaware in September 1996 as a holding
company for the existing business of IAT AG ("IAT AG") and IAT Deutschland GmbH
Interaktive Medien Systeme ("IAT Germany") which were organized in 1989 and
1991, respectively. IAT AG is a wholly-owned subsidiary of IAT and IAT Germany
is a 74.9% subsidiary of IAT AG. HIBEG, a wholly-owned subsidiary of the federal
state of Bremen, Germany which promotes business, is the holder of 25.1% of the
outstanding share capital of IAT Germany. The Company's executive offices are
located at Geschaftshaus Wasserschloss, Aarestrasse 17, CH-5300,
Vogelsang-Turgi, Switzerland and its telephone number is (011)(41)(56) 223-5022.

                  SUMMARY CONSOLIDATED FINANCIAL INFORMATION 

   The following historical financial data, except for the information 
provided for the nine months ended September 30, 1995 and 1996, have been 
derived from historical consolidated financial statements of the Company that 
have been audited by Rothstein, Kass & Company, independent auditors (the 
"Consolidated Financial Statements"). The historical financial data provided 
for the nine months ended September 30, 1995 and 1996 are unaudited (the 
"Consolidated Interim Financial Statements," and together with the 
Consolidated Financial Statements, the "Financial Statements"), but in the 
opinion of the Company's management contain all adjustments, consisting only 
of normal recurring accruals, which are necessary for a fair presentation of 
the information included herein. Multimedia was formed in September 1996 as a 
holding company for the existing operations of IAT AG and IAT Germany. 


   The pro forma consolidated balance sheet data reflect the issuance of 
1,875,000 shares of Series A Preferred Stock in October 1996 and the 
conversion of the Series A Preferred Stock into 1,875,000 shares of Common 
Stock and the as adjusted consolidated balance sheet data reflect the 
Company's consolidated financial position as of September 30, 1996, giving 
effect to the sale of the Units offered hereby at an assumed price per Unit 
of $6.00, assuming no exercise of the Underwriter's Over-Allotment Option, 
the application of the net proceeds therefrom, including the repayment of a 
loan made by a stockholder of the Company in the amount of $1,182,000 
(including loans received subsequent to September 30, 1996), the payment of 
$500,000 ($100,000 of which was paid in October 1996) pursuant to the 
Marketing Agreement, and the issuance of 1,875,000 shares of Common Stock 
issuable upon the automatic conversion of all of the outstanding shares of 
Series A Preferred Stock upon consummation of this Offering.

business. These forward- looking statements are based largely on the 
Company's expectations and are subject to a number of risks and 
uncertainties, certain of which are beyond the Company's control. Actual 
results could differ materially from these forward-looking statements as a 
result of a number of factors including, but not limited to, the Company's 
ability to successfully complete the development of its third generation 
products, the ability to achieve market penetration, the need for additional 
financing, intense competition in various aspects of its business, the 
Company's ability to expand into the United States, its dependence on key 
personnel, and other factors described in the Risk Factors sections set forth 
below and elsewhere herein. In light of these risks and uncertainties, there 
can be no assurance that the forward-looking information contained in this 
Prospectus will in fact take place or prove to be accurate. In addition to 
the other information contained in this Prospectus (including the Financial 
Statements and the notes thereto), prospective investors should carefully 
consider the following risk factors before purchasing the Units offered 
hereby. 

   History of Operating Losses and Going Concern. The Company incurred net 
losses of approximately $1.3 million, $3.7 million and $3.7 million in the 
years ended December 31, 1994 and December 31, 1995 and in the nine months 
ended September 30, 1996, respectively. At September 30, 1996, the Company 
had an accumulated deficit of approximately $10.9 million and a stockholder's 
deficiency of approximately $2.9 million. While the Company's products have 
been marketed for several years, the Company's products are still in the 
development stage and have generated limited sales to date which has resulted 
in operating losses. The Company is in the process of developing a third 
generation of its products which it expects to release during 1997. However, 
there can be no assurance that the products incorporating the Company's third 
generation technology will be completed, will be released in a timely manner, 
can be manufactured at the anticipated reduced costs, will be sold at the 
reduced purchase price or will achieve market acceptance and penetration. In 
the years ended December 31, 1994 and December 31, 1995 and the nine months 
ended September 30, 1996, the Company made significant expenditures of 
approximately $62,000, $1.7 million and $1.7 million for product development 
and expects that it will be required to continue to invest heavily in product 
development and marketing programs in order to be competitive in a rapidly 
developing technology market and to capture market share in the segments of 
the multimedia market in which it seeks to compete. As a result, the Company 
may incur further losses in the future. There can be no assurance that the 
Company will achieve profitable operations in any future period, if at all. 

   Multimedia's subsidiaries are subject to German and Swiss law, which 
require, among other things, that companies which incur losses have to take 
appropriate measures to ensure that the claims of the company's obligees are 
covered by the assets of those companies. Such measures include, among 
others, increasing paid-in capital or obtaining declarations from the 
obligees which subordinate their claims. If those measures are not taken, the 
board of directors of the subsidiaries must notify a judge in order to 
commence bankruptcy proceedings which, under Swiss and German law, usually 
leads to the dissolution of the corporate existence. Between May 1992 and 
April 1993, in accordance with Swiss law, IAT AG underwent a financial 
reorganization and has been obligated to take the measures described herein 
on various occasions. While IAT AG and IAT Germany have successfully 
undertaken these measures in the past, there can be no assurance that such 
measures will not have to be undertaken in the future or that the corporate 
existence of IAT AG and IAT Germany can be maintained. Failure to maintain 
such corporate existence would have a material adverse effect on the Company. 
See "Certain Transactions." 

   Potential investors should be aware that the report of the Company's 
independent certified public accountants relating to the Company's December 
31, 1995 Consolidated Financial Statements contains an explanatory paragraph 
expressing substantial doubt about the Company's ability to continue as a 
going concern as a result of the Company's recurring losses and working 
capital and stockholder's deficits. See "Management's Discussion and Analysis 
of Financial Condition and Results of Operations" and "Note 8 -- Consolidated 
Financial Statements of the Company."

   Dependence Upon Agreements. The Company's ability to develop, modify, market
and distribute its products derives in large part from its agreements with Texas
Instruments, DT, IBM Germany, Olympus. These agreements do not grant the Company
exclusive licenses, and the Company's Strategic Partners may, at any time,
develop products or technology which compete with those of the Company. In
addition, the Company's Strategic Partners may, under certain circumstances
grant licenses to other companies, including competitors of the Company, to
develop, sell and sublicense versions of the products developed in conjunction
with the Company. The Company intends to use the technology developed with its
Strategic Partners to design high quality systems which provide solutions
tailored to the requirements of particular customers of the Company. As a
result, the Company may need to collaborate with its Strategic Partners to
create solutions, which could require the Company to enter into new agreements
with its Strategic Partners. There can be no assurance that the Company will be
able to enter into such agreements in the future or that such agreements will
contain terms acceptable or beneficial to the Company.

   The Company's agreements with its Strategic Partners generally have fixed 
terms and, unless extended, many of the agreements may terminate during the 
next year. There can be no assurance that these agreements will be extended 
or renewed or if they are renewed that the terms will be acceptable or 
beneficial to the Company. In addition, the Company may determine that 
additional agreements with its existing Strategic Partners or future partners 
may be necessary. Failure to extend or renew these agreements or enter into 
new agreements could have a material adverse effect on the Company's 
business, financial condition and results of operations. See "Business -- 
Agreements with Strategic Partners." 

   Limited Proprietary Protection. The Company's success is heavily dependent 
upon its proprietary technology. The Company currently has no patents and 
relies primarily on copyright, trademark and trade secrets law, as well as 
third-party non-disclosure agreements, to protect its intellectual property. 
There can be no assurance that the steps taken by the Company to protect its 
proprietary rights will be adequate to prevent misappropriation of its 
technology or independent development by others of similar technology. 

   In addition, the laws of some foreign countries do not protect the 
Company's proprietary rights to the same extent as do laws in the United 
States. There can be no assurance that the protections afforded by the laws 
of such countries will be adequate to protect the Company's proprietary 
rights, the unenforceability of any of which could have a material adverse 
effect on the Company's business, financial condition and results of 
operations. 

   Litigation may be necessary to enforce the Company's intellectual property 
rights or to protect the Company's trade secrets. There can be no assurance 
that any such litigation would be successful. Any such litigation, whether or 
not successful, could result in substantial costs and diversion of resources 
and could have a material adverse effect on the Company's business, financial 
condition and results of operations. 

   The Company has not been charged with infringement of any proprietary
rights of others; however, there can be no assurance that third parties will
not assert infringement and other claims against the Company or that such
claims will not be successful. From time to time, the Company may receive in
the future notice of claims of infringement of other parties' proprietary
rights. Many participants in the Company's industry have an increasing number
of patents and have frequently demonstrated a readiness to commence litigation
based on allegations of patent or other intellectual property infringement.
Third parties may assert exclusive patent, trademark, copyright and other
intellectual property rights to technologies that are important to the
Company. There can be no assurance that infringement or invalidity claims (or
claims for indemnification resulting from infringement claims) will not be
asserted or prosecuted against the Company or that any such assertion or
prosecution will not have a material adverse effect on the Company's business,
financial condition or results of operations. Regardless of the validity or
the successful assertion of any such claims, the Company could incur
significant costs and diversion of resources in defending such claims, which
could have a material adverse effect on the Company's business, financial
condition and results of operations. Furthermore, any party making such claims
could secure a judgment awarding substantial damages, as well as injunctive or
other equitable relief, which could effectively block the Company's ability to
make, use, sell, distribute or market its products and services in the United
States or abroad. Any such judgment could have a material adverse effect on
the Company's business, financial condition and results of operations. In
circumstances where claims relating to proprietary technology or information
are asserted against the Company, the Company may be required to seek licenses
to such intellectual property. There can be no assurance, however, that such
licenses would be available or, if avail-

                                      12 
<PAGE>

able, that such licenses could be obtained on terms that are commercially 
reasonable and acceptable to the Company. The failure to obtain the necessary 
licenses or other rights could preclude the sale, manufacture or distribution 
of the Company's products and, therefore, could have a material adverse 
effect on the Company's business, financial condition and results of 
operations. See "Business -- Intellectual Property." 


   Further Development; Need for Additional Financing. The Company's business 
will continue to require additional expenditures for research and 
development, sales and marketing, the expansion into the United States and, 
to the extent losses continue, working capital. The Company intends to use a 
portion of the proceeds of this Offering for the repayment of certain 
stockholder loans, the payment of a dividend on the Series A Preferred Stock 
and the payment of a fee pursuant to the Marketing Agreement. The Company 
anticipates that the remaining proceeds of this Offering will be sufficient 
to fund its operations through 1998. This estimate assumes substantial 
increases in the Company's sales, completion of the Company's third 
generation of products and acceptance of these products in the visual 
communications market. There can be no assurance that the Company will be 
able to achieve such increased sales. Failure to achieve such increase will 
require the Company to seek additional funding prior to 1998. The Company's 
existing bank lines of credit in the aggregate amount of approximately $2.2 
million are due on demand and there can be no assurance that the Company's 
lenders will continue to extend credit to the Company. In the event the 
Company's sales do not increase substantially and in the event expected cash 
flow generated from future operations is not sufficient to fund ongoing 
operations, the Company will require additional financing. The Company has no 
commitments to obtain additional financing and there can be no assurance that 
such financing will be available on terms that are satisfactory to the 
Company, or at all. Failure to obtain such additional financing on terms that 
are satisfactory to the Company, or at all, could have a material adverse 
effect on the Company's business, financial condition and results of 
operations. Any additional equity financings may be dilutive to stockholders, 
and debt financings, if available, may involve restrictive covenants. See 
"Use of Proceeds" and "Management's Discussion and Analysis of Financial 
Condition and Results of Operations -- Liquidity and Capital Resources." 

   Developing Market. The multimedia communications market has only recently 
begun to develop, continues to be defined, is evolving rapidly and is 
characterized by a large number of market entrants. Moreover, the Company 
intends to market its technology and its products to the professional market 
which is not currently utilizing visual communications systems. The Company 
believes that this market requires high quality systems which provide 
solutions tailored to its requirements and contain higher quality image and 
video transmissions, including reduced noise and artifacts, true color 
representation and higher frame rates, than traditional video conferencing 
communications systems. Such market includes customers using tele-medicine 
and tele- surveillance. The Company's success in this market will be 
dependent in part upon its ability, and in certain cases, the ability of its 
Strategic Partners, to convince potential customers that the Company's 
products satisfy their needs and to purchase those products. In addition, the 
Company has only released pilots of its MIKS Interactive Kiosk systems to 
customers, such as supermarkets, airports and train stations, for evaluation, 
and has not had any commercial sales of such product to date. There can be no 
assurance that potential customers in this market will accept the Company's 
technology and products, that the Company will be successful in creating 
solutions tailored to the requirements of these potential customers or that a 
market for the Company's products will become established. In addition, the 
Company's future success will depend in large part on the continued expansion 
of the multimedia communications market in general, the expansion of the 
professional market specifically, the identification of customers with 
technological requirements which can be met by the Company's systems in 
particular and the acceptance of the Company's systems. As is typical in a 
rapidly evolving industry, demand for and acceptance of products are subject 
to a high level of uncertainty. Certain factors, including the 
incompatibility of the Company's current visual communications systems with 
certain vendors' video conferencing products, the level of technical skill 
required by the operator of the Company's systems and the willingness on the 
consumer's part to await the next generation of more advanced equipment may 
limit demand for and acceptance of the Company's products. In addition, sales 
of systems introduced into the multi-media communications market requires 
intense effort over long periods of time. 

   Furthermore, new customers typically acquire a pilot system to evaluate 
before purchasing systems. In many cases, customers need to purchase a number 
of systems to meet their requirements and such purchases require the approval 
of the customer's senior management or board of directors prior to the 
purchase, which could lead to delays in the purchase or, in some cases, 
eliminate decisions to purchase the Company's products. See "-- Dependence on 
New Products and Rapidly Developing Technologies." 


                                      13 
<PAGE>


   Dependence on New Products and Rapidly Developing Technologies. While the 
Company's products have been marketed for several years, the Company's 
products have generated limited sales to date. The Company's second 
generation MFKS 128 and MFKS 384 systems have prices of approximately $8,000 
to $30,000, respectively. Because of the costs of manufacturing the second 
generation and the resulting sales price, the Company does not believe that 
it could achieve market penetration in the market for which its products are 
intended. The Company expects to release the third generation of MFKS systems 
in 1997 at target prices of approximately $1,500 per system ($1,000 to OEMs 
in quantity) for the single board MFKS 128 system and approximately $8,000 
per system ($3,500-$4,500 to OEMs depending on configuration) for the MFKS 
384 system. To date, the Company has only installed pilots of its second 
generation MIKS Interactive Kiosk systems which sell for approximately 
$45,000 per electronic kiosk. The Company intends to introduce its third 
generation of MIKS Interactive Kiosks during 1997 at a price of approximately 
$20,000. In addition, the Company intends to use the technology developed 
with its Strategic Partners and its basic MFKS Vision and Live and MIKS 
Interactive Kiosk systems to design solutions tailored to the requirements of 
particular customers of the Company. There can be no assurance that the third 
generation of MFKS Vision and Live or MIKS Interactive Kiosk will be 
completed, will be released in a timely manner, can be manufactured at the 
anticipated reduced costs, will be sold at the reduced purchase price or will 
achieve market acceptance and penetration. Furthermore, if the market for 
these products is established, competitors of the Company may develop and 
manufacture products similar to the Company's products and may be able to 
manufacture competitive products which provide higher quality than the 
Company's systems or can be manufactured at lower cost. See "-- Developing 
Market." 

   In addition, the Company's systems are subject to rapid technological 
change and product obsolescence. The Company has primarily focused on 
developing its technology and products and believes that its future success 
will depend in part upon its ability to develop and enhance its existing 
products and develop new products and to meet such anticipated technological 
changes. To the extent products developed by the Company are based upon 
anticipated changes, sales for such products may be adversely affected if 
other technology becomes accepted in the industry. If the Company does not 
successfully introduce new products or enhanced versions of its current 
products in a timely manner, any competitive position the Company has or may 
develop could be lost and the Company's sales would be reduced. There can be 
no assurance that the Company will be able to develop and introduce enhanced 
or new products which satisfy a broad range of customer needs and achieve 
market acceptance. See "Business -- Systems." 

   Supply. Certain critical components and parts used in the Company's 
systems, including the C8x, are procured from a single source. The Company 
believes that the C8x will substantially decrease the cost of the hardware 
the Company uses in its third generation systems and is necessary to permit 
the Company's systems to be sold at prices which create the potential for 
market penetration. The C8x is only manufactured by Texas Instruments and the 
Company does not have any other source for obtaining a programmable digital 
signal processor which would provide the Company with the same functions at a 
similar price. The Company obtains other parts and certain components only 
from a single supplier of such parts or components, even where multiple 
sources are available, to maintain quality control and enhance the working 
relationship with suppliers. The Company does not have supply contracts with 
any of its vendors and purchases are made with purchase orders. The failure 
of a supplier, including Texas Instruments, to deliver on schedule, or at 
all, would delay or interrupt the Company's delivery of systems and thereby 
could have a material adverse effect on the Company's business, financial 
condition and results of operations. 


   Competition. The visual communications business is highly competitive. The 
Company estimates that more than 100 companies world-wide offer products 
which compete in its market segments and expects that whether or not the 
Company is successful in capturing market share, the competition will 
intensify in the future. The Company believes that the majority of its 
competitors focus on low-cost products or closed device solutions such as 
videophones. The Company believes that the principal competitive factors in 
the visual communications industry are price, video and audio quality, the 
ability to connect auxiliary devices such as video diskplayers, reliability, 
service and support, and vendor and product reputation. The Company believes 
that its ability to compete successfully will depend on a number of factors 
both within and outside its control, including the adoption and evolution of 
industry standards, the pricing policies of its competitors and suppliers, 
the timing of the introduction of new systems and services by the Company and 
others, the Company's ability to hire and retain employees, and industry and 
general economic trends. The Company anticipates that in the near future the 
visual 

                                      14 
<PAGE>


communications market will continue to polarize with certain providers 
focusing on capturing the mass consumer market with lower quality and less 
costly software-only products or products based on hardwired chips while the 
Company will continue to seek to provide hardware and software systems for a 
more specialized and dedicated market. The Company intends to market its 
technology and its products to professional customers who are not currently 
utilizing video conferencing communications systems. If the market for these 
products is established, competitors of the Company may begin to manufacture 
products similar to the Company's products. In addition, while the Company 
believes that it has created proprietary technology and advantages in 
manufacturing its products and that a competitor would require significant 
investment and the efforts of a highly-skilled team, there are no barriers 
restricting competitors from entering into the market in which the Company's 
intends to sell its products. While the Company believes the mass market 
solutions do not meet the needs of its customers, the availability of these 
products may have an adverse effect on the pricing of the Company's products. 


   Many of the Company's current and potential competitors, have 
significantly longer operating histories and/or significantly greater 
managerial, financial, marketing, technical and other competitive resources, 
as well as greater name recognition, than the Company. As a result, the 
Company's competitors may be able to adapt more quickly to new or emerging 
technologies and changes in customer requirements and may be able to devote 
greater resources to the promotion and sale of their products and services. 
There can be no assurance that the Company will be able to compete 
successfully with existing or new competitors. In addition, competition could 
increase if new companies enter the market or if existing competitors expand 
their service offerings. An increase in competition could result in material 
price reductions or loss of market share by the Company and could have a 
material adverse effect on the Company's business, financial condition and 
results of operations. 

   To remain competitive, the Company will need to continue to invest in 
research and development and sales and marketing. There can be no assurance 
that the Company will have sufficient resources to make such investments or 
that the Company will be able to make the technological advances and 
adaptions necessary to remain competitive. In addition, current and potential 
competitors have established or may in the future establish collaborative 
relationships among themselves or with third parties, including the Company's 
Strategic Partners, to increase the visibility and utility of their products 
and services. Accordingly, it is possible that new competitors or alliances 
may emerge and rapidly acquire significant market shares. Such an eventuality 
could have a material adverse effect on the Company's business, financial 
condition and results of operations. See "Business -- Competition." 


   Risks Associated With Expanded Operations in the United States. As part of 
its business strategy, the Company intends to seek opportunities to expand 
the sale of its products into markets in the United States. The Company 
believes that expansion into the United States markets is critical to the 
Company's ability to continue to grow and to market its systems. Failure to 
successfully expand into the United States market would have a material 
adverse effect on the Company's business, financial condition and results of 
operations. In marketing its systems in the United States, the Company will 
likely face new competitors. There can be no assurance that the Company will 
be successful in marketing or distributing systems in this market or that its 
revenue generated in the United States will be adequate to offset the expense 
of establishing and maintaining operations. In addition, in connection with 
its expansion, the Company will be required to make substantial expenditures 
for, among other things, office space, sales and marketing personnel and 
distributors in the United States. Competition for such personnel is intense 
and the Company will compete for qualified personnel with numerous other 
employers, some of whom have greater financial and other resources than the 
Company. There can be no assurance that the Company will be able to hire and 
retain qualified employees in the United States. See "Business -- Strategy." 

   Foreign Markets. Substantially all of the Company's revenues in the years 
ended December 31, 1994 and 1995 and in the nine months ended September 30, 
1996 were generated from operations located in Germany and Switzerland. While 
these countries have well developed economic markets, the average annual 
growth has averaged 2.8% in 1994 and 1.9% in 1995 for Germany and 2.1% in 
1994 and 0.8% in 1995 for Switzerland, respectively. Historically, all of the 
Company's revenues have been denominated in Swiss Francs and Deutsche Marks 
and the Company anticipates that it will continue to generate most of its 
revenues in these currencies in the foreseeable future. Any fluctuations in 
the value of the Swiss Franc or Deutsche Mark against the U.S. dollar that 


                                      15 
<PAGE>


the Company is unable to offset through price adjustments could have a 
material adverse effect on the Company's financial condition and results of 
operations. Conducting an international business inherently involves a number 
of other difficulties and risks, such as export restrictions, export controls 
relating to technology, compliance with existing and changing regulatory 
requirements, tariffs and other trade barriers, difficulties in staffing and 
managing international operations, longer payment cycles, problems in 
collecting accounts receivable, software piracy, political instability, 
seasonal reductions in business activity in Europe during the summer months, 
and potentially adverse tax consequences. There can be no assurance that one 
or more of these factors will not have a material adverse effect on any 
international operations established by the Company and, consequently, on the 
Company's business, financial condition and results of operations. In 
addition, the Company intends to have operations in the United States and in 
other countries. There can be no assurance that transfers of funds to and 
from those countries to Germany and Switzerland will not be taxable events 
for the Company. The Company's results of operations, the market price of the 
Units, the Common Stock and the Warrants offered hereby may be affected by 
changes in German and Swiss policy, taxation and economic developments. See 
"Exchange Rates." 

   Enforcement of Civil Liabilities. Multimedia is organized under the laws 
of the State of Delaware. Investors in the Units will be able to effect 
service of process in the United States upon the Company. However, the 
Company is primarily a holding company which holds stock in entities in 
Switzerland and Germany and all or a substantial portion of the assets of the 
Company are located outside the United States. In addition, all of the 
Company's four directors and all of its executive officers are residents of 
foreign countries and all or a substantial portion of the assets of such 
directors and officers are located outside of the United States. As a result, 
it may not be possible for investors to enforce to effect service of process 
upon Multimedia's directors and officers or to judgments of U.S. courts 
predicated upon the civil liability provisions of U.S. laws against the 
Company's, the foreign directors' and officers' assets. 

   The Company has been advised by its counsel, Baker & McKenzie, that there 
is doubt as to the enforceability in Switzerland of judgments of U.S. courts, 
against Multimedia's subsidiaries and against stockholders, directors, 
officers and employees of Multimedia or its subsidiaries who are domiciled in 
Switzerland. In addition, awards of punitive damages in actions brought in 
the United States or elsewhere may be unenforceable in Switzerland. 

   The Company has been advised by its counsel, Dr. Schackow & Partner, that 
there is doubt as to the enforceability in Germany in original actions or in 
actions for enforcement of judgments of U.S. courts, of civil liabilities 
predicated solely upon the laws of the United States against Multimedia's 
subsidiaries and against stockholders, directors, officers and employees of 
Multimedia or its subsidiaries who are domiciled in Germany. In addition, 
awards of punitive damages in actions brought in the United States or 
elsewhere may be unenforceable in Germany. 

   The market price of the Units, the Common Stock and the Warrants offered 
hereby may be affected by the impossibility for investors to enforce 
judgements of U.S. courts. 


   Dependence on Key Personnel. The Company's success depends upon the 
contributions of its current executive officers including Dr. Viktor Vogt, 
the Co-Chairman and Chief Executive Officer of the Company with whom the 
Company intends to enter into an employment agreement. In addition, the 
Company employs a number of highly specialized computer engineers who are an 
integral part of the Company's operations. There can be no assurance that 
these individuals will continue to devote sufficient time to the Company's 
business. The loss of services of, or a material reduction in the amount of 
time devoted to the Company by, certain of such individuals could adversely 
affect the business of the Company. The Company intends to obtain key-man 
insurance for its benefit in the amount of $2 million on Dr. Vogt. See 
"Management" and "Certain Transactions." 

   Dependence on Major Customer. Approximately 86%, 87%, 68% and 87% of the
Company's revenues for the years ended December 31, 1993, 1994 and 1995 and
the nine months ended September 30, 1996, respectively have been received from
DT and its affiliates. The Company currently anticipates that DT and its
affiliates will remain large customers of the Company but there can be no
assurance that sales to DT and its affiliates will continue at their historic
levels. The Company's volume of sales to DT and its affiliates has dropped in
the third and fourth quarters of 1996 from the corresponding periods in the
prior year as these customers awaited the release of the Company's third
generation systems.The loss of sales or a significant reduction in sales to DT
and its affiliates could have a material adverse effect on the Company's
business, financial condition and results of operations. See "Business --
Customers."

   Risks Associated with Creating and Accessing New Distribution Channels. In
addition to marketing its products independently or jointly with certain of its
Strategic Partners, the Company's strategy for marketing its products

                                      16 
<PAGE>

is to license its products to OEMs and integrators who have access to a wide 
range of competing products. The Company expects that its future success will 
depend in large part upon these OEMs and integrators. The performance of 
those OEMs and integrators will be outside the control of the Company, and 
the Company is unable to predict the extent to which these organizations will 
be successful in marketing and selling their products. The Company's failure 
to establish relationships with OEMs and integrators could have a material 
adverse effect on the Company's business, financial condition and results of 
operations. 

   Risk of System Defects; Product Liability Exposure. Systems developed by 
the Company jointly with its Strategic Partners may contain significant 
undetected errors when first installed on the premises of a customer or as 
new versions are installed. Although the Company tests its systems before 
installation, there can be no assurance that errors in the system will not be 
found after customers begin to use the system. Any error in the Company's 
products may result in decreased revenue or increased expenses because of 
adverse publicity, reduced orders, product returns, uncollectible accounts 
receivable, delays in collecting accounts receivable, and additional and 
unexpected costs of further product development to correct the errors. Sale 
of the Company's products involves the inherent risk of product liability 
claims against the Company. The Company currently does not maintain product 
liability insurance and believes that it cannot obtain such insurance except 
at substantial cost. While no product liability claims have been made against 
the Company in the past, there can be no assurance that such claims will not 
arise in the future. Any substantial uninsured liability would have a 
material adverse effect on the Company's operations, financial conditions and 
results of operations. 

   Potential Fluctuations in Quarterly Results. The Company has experienced 
fluctuations in its quarterly results of operations and anticipates that such 
fluctuations will continue and could increase. The Company's quarterly 
results of operations may vary significantly depending on a number of 
factors, some of which are outside of the Company's control. These factors 
include the timing of the introduction or acceptance of new products or new 
generations offered by the Company or its competitors, changes in the mix of 
products provided by the Company, changes in pricing strategies by the 
Company and its competitors, changes in the markets served by the Company, 
changes in the Company's operating expenses, capital expenditures and other 
costs relating to the expansion of operations, changes in its personnel and 
general economic conditions. In addition, fluctuations in exchange rates may 
render the Company's products less competitive relative to local product 
offerings or result in foreign exchange losses. In the future, the Company 
may seek to implement hedging techniques with respect to its foreign currency 
transactions but there can be no assurance that such hedging techniques will 
be successful. The Company's revenue in the fourth quarter of each calendar 
year has historically been higher due to the introduction of new products and 
new generations of existing products in the second and third quarters of past 
years, the extended time period required for the approval by management of a 
customer for the purchase of the Company's products and perceived desire by 
its customers to apply allocated budgets for the Company's products prior to 
the end of the calendar year and the increase in business activity after the 
summer months. Quarterly fluctuations depends, in part, on the timing of 
introduction of new products by the Company and its competitors. The Company 
expects its sales for the fourth quarter of 1996 not to be as high 
proportionately as in past years as the Company's customers await the release 
of the Company's third generation systems. Fluctuations in results of 
operations may result in volatility in the price of the Units, the Common 
Stock and the Warrants offered hereby. 

   A significant portion of the Company's expenses are fixed and difficult to 
reduce in the event that revenue does not meet the Company's expectations, 
thus magnifying the adverse effect of any revenue shortfall. Furthermore, 
announcements by the Company or its competitors of new products, services or 
technologies could cause customers to defer or cancel purchases of the 
Company's products. Any such deferral or cancellations could have a material 
adverse effect on the Company's business, financial conditions and results of 
operations. Accordingly, revenue shortfalls can cause significant variations 
in results of operations from quarter to quarter and could have a material 
adverse effect on the Company's business, financial condition and results of 
operations. 

   As a result of the foregoing factors, it is possible that in some future 
quarters the Company's results of operations will be below prior results or 
the expectations of public market analysts and investors. In such event, the 
price of the Units, the Common Stock and the Warrants offered hereby would 
likely be materially and adversely affected. See "Management's Discussion and 
Analysis of Financial Condition and Results of Operations."

   Benefits of the Offering to Insiders. The Company intends to use a portion of
the net proceeds of the Offering (i) to repay loans aggregating approximately
$1.2 million made to the Company by Volker Walther, a stockholder and a director
of the Company, (ii) to pay a $400,000 marketing fee payable to General Capital,
an affiliate of Vertical Financial Holdings ("Vertical") a stockholder of the
Company, pursuant to the Marketing Agreement, as amended, between Multimedia and
General Capital (the "Marketing Agreement"), (iii) to pay the salaries of its
executive officers and (iv) to make monthly payments of $12,000 to Vertical as
compensation for the services, the Co-Chairman of the Company nominated by
Vertical, pursuant to the provisions of the Stock Purchase Agreement among
Multimedia, IAT AG, IAT Germany and Vertical (the "Stock Purchase Agreement").
See "Use of Proceeds," "Management" and "Certain Transactions."

   Control by Existing Stockholders; Potential Anti-takeover Provisions. 
Upon completion of this Offering the Company's existing stockholders will 
control approximately 66.85% of the outstanding Common Stock of the Company. 
As a result, such stockholders will be able to elect all of the Company's 
directors and otherwise control the Company's operations. 

   Furthermore, the Company and Vertical, one of the Company's stockholders, 
have entered into an investor rights agreement (as defined herein), which 
provides that so long as Vertical holds at least 10% of the Common Stock to 
be issued upon conversion of the Series A Preferred Stock, Vertical has the 
right, but not the obligation, to nominate two persons as nominees for 
election to the Company's Board of Directors. So long as Vertical holds at 
least 5% of such securities, it has the right, but not the obligation to 
nominate one such person. The existence of such rights solidifies control 
over the Company by its existing stockholders. Pursuant to the Investor 
Rights Agreement, Vertical has nominated and the stockholders of the Company 
have elected Jacob Agam as a director of the Company and may elect the second 
director in the future. Pursuant to the Stock Purchase Agreement, Vertical 
nominated and Mr. Agam was elected as the Co-Chairman of the Company. Mr. 
Agam is a director of Vertical. 

   The Company is also subject to a Delaware statute regulating business 
combinations, which could discourage, hinder or preclude an unsolicited 
acquisition of the Company and could make it less likely that stockholders 
receive a premium for their shares as a result of any such attempt. See 
"Certain Transactions," "Principal Stockholders" and "Description of 
Securities." 

   Possible Adverse Effects of Authorization of Preferred Stock. Multimedia's
Amended and Restated Certificate of Incorporation (the "Certificate of
Incorporation") authorizes the issuance of 500,000 shares of preferred stock,
par value $.01 per share ("Blank Check Preferred Stock"), on terms which may be
fixed by the Company's Board of Directors without further stockholder action.
The terms of any series of Blank Check Preferred Stock, which may include
priority claims to assets and dividends and special voting rights, could
adversely affect the rights of holders of the Common Stock. The issuance of the
Blank Check Preferred Stock, while providing flexibility in connection with
possible acquisitions, financing transactions and other corporate transactions,
could have the effect of making it more difficult for a third party to acquire,
or of discouraging a third party from acquiring, capital stock of the Company,
which may adversely affect the market price of the Common Stock. The Company has
no present plans to issue shares of Blank Check Preferred Stock. See "-- Control
by Existing Stockholders; Potential Anti-takeover Provisions" and "Description
of Capital Stock -- Preferred Stock."

   Immediate and Substantial Dilution; Recent Sales of Securities to 
Insiders.  Investors participating in this Offering will incur immediate and 
substantial dilution in net tangible book value of approximately $4.42 per 
share, assuming an initial public offering price of $6.00 per Unit. During 
1996, IAT AG and Multimedia have issued shares to their respective 
stockholders to finance working capital needs. IAT AG issued 2,000 shares of 
its capital stock to its existing stockholders (which were exchanged for 
875,000 shares of Multimedia) at a purchase price equivalent to approximately 
$1.76 per share of Common Stock of Multimedia. In October 1996, Multimedia 
completed the private placement of the Series A Preferred Stock (the "Private 
Placement") pursuant to which it sold 1,875,000 shares of Series A Preferred 
Stock and the Investor Warrants for an aggregate purchase price of $1.5 
million, or $.80 per share of Series A Preferred Stock (which will 
automatically convert upon completion of this Offering into 1,875,000 shares 
of Common Stock). In addition, in connection with the Private Placement, the 
Company issued the Stockholder Warrants to purchase 473,485 shares of Common 
Stock. The Investor Warrants and the Stockholder Warrants are exercisable 
into an aggregate of 2,348,485 shares of Common Stock at an exercise price of 
130% of the initial public offering price of the Common Stock. See 
"Dilution." and "Certain Transactions -- Private Placement and Related 
Transactions."

   Charge to Earnings in the Event of Release of Escrow Shares. Following 
completion of this Offering, the Company will have outstanding 500,000 Escrow 
Shares which will be released from escrow if the Company attains certain 
earnings levels over the next one to three years or if the Common Stock 
trades at certain levels for any 30 consecutive trading days, commencing 24 
months after the consummation of this Offering. The Escrow Shares will not be 
deemed to be outstanding for the purpose of calculating earnings per share 
until either of such conditions is probable of being met. The position of the 
Securities and Exchange Commission (the "Commission") with respect to such 
escrow arrangements provides that in the event any shares are released from 
escrow to the stockholders of the Company who are officers, directors, 
employees or consultants of the Company, a non-cash compensation expense will 
be recorded for financial reporting purposes. Accordingly, in the event of 
the release of the Escrow Shares, the Company will recognize during the 
period in which the earnings thresholds are probable of being met or such 
stock levels achieved, a substantial non-cash charge to operations, which 
will not be deductible for income tax purposes, equal to the then fair value 
of such shares, which would have the effect of significantly increasing the 
Company's loss or reducing or eliminating earnings, if any, at such time. The 
recognition of such compensation expense may depress the market price of the 
Company's securities. See "Management's Discussion and Analysis of Financial 
Condition and Results of Operations" and "Principal Stockholders -- Escrow 
Shares." Notwithstanding the foregoing discussion, there can be no assurance 
that the Company's earnings or its stock price will attain the targets that 
would enable the Escrow Shares to be released from escrow. 

   Dividend Policy. The Company has never declared or paid a cash dividend on 
its Common Stock. The Company intends to retain its earnings, if any, for use 
in its business and does not anticipate paying cash dividends in the 
foreseeable future. See "Dividend Policy." 

   No Public Market for Securities; Possible Volatility of Market Price; 
Arbitrary Determination of Offering Price. Prior to this Offering, there has 
not been any market for any of the Company's securities, and there can be no 
assurance that an active trading market will develop or be sustained after 
this Offering. The initial public offering price of the Units and the 
exercise price and other terms of the Warrants have been determined by 
negotiation between the Company and the Underwriter and are not necessarily 
related to the Company's asset value, net worth, results of operations or any 
other criteria of value and may not be indicative of the prices that may 
prevail in the public market. In recent years, the stock markets in general, 
and the shares of technology companies in particular, have experienced 
extreme price fluctuations in response to such occurrences as quarterly 
variations in operating results, changes in earnings estimates by analysts, 
announcements concerning new products, strategic relationships or 
technological innovations by companies in the visual communications market, 
general conditions of such industry and other events or facts. This pattern 
of extreme volatility in the stock market, which in many cases were unrelated 
to the operating performance of, or announcements concerning, the issuers of 
the affected stock may adversely affect the market price of the Units, the 
Common Stock and the Warrants. See "Underwriting." 

   Potential Adverse Effect of Redemption of Warrants. Commencing 15 months 
from the date of this Prospectus, the Warrants may be redeemed by the Company 
at a redemption price of $.05 per Warrant upon not less than 30 days' prior 
written notice if the closing bid price of the Common Stock equals or exceeds 
$16.00 per share (subject to certain adjustments) for 20 consecutive trading 
days ending within five days of the notice. Redemption of the Warrants could 
force the holders to exercise the Warrants and pay the exercise price 
therefor at a time when it may be disadvantageous for the holders to do so, 
to sell the Warrants at the then current market price when they might 
otherwise wish to hold the Warrants or to accept the nominal redemption price 
which, at the time the Warrants are called for redemption, is likely to be 
substantially less than the market value of the Warrants. See "Description of 
Securities -- Warrants." 

   Current Prospectus and State Registration to Exercise Warrants. Holders of 
Warrants will only be able to exercise the Warrants if (i) a current 
prospectus under the Securities Act relating to the securities underlying the 
Warrants is then in effect and (ii) such securities are qualified for sale or 
exempt from qualification under the applicable securities laws of the states 
in which the various holders of Warrants reside. Although the Company has 
undertaken and intends to use its best efforts to maintain a current 
prospectus covering the securities underlying the Warrants following 
completion of this Offering to the extent required by Federal securities 
laws, there can be no assurance that the Company will be able to do so. The 
value of the Warrants may be greatly reduced if a prospectus covering the 
securities issuable upon the exercise of the Warrants is not kept current or 
if the securities are not qualified, or exempt from qualification, in the 
states in which the holders of Warrants reside. 

                                      19 
<PAGE>

If and when the Warrants become redeemable by the terms thereof, the Company 
may exercise its redemption right even if it is unable to qualify the 
underlying securities for sale under all applicable state securities laws. As 
indicated above, holders of Warrants called for redemption residing in states 
where the underlying securities have not been qualified for sale would 
generally still be able to sell their Warrants at the then market price 
thereof. See "Description of Securities -- Warrants." 

   Possible Restrictions on Market-Making Activities in Company's 
Securities.  The Underwriter has advised the Company that it intends to make 
a market in the Company's securities. Rule 10b-6 under the Securities 
Exchange Act of 1934, as amended (the "Exchange Act"), may prohibit the 
Underwriter from engaging in any market-making activities with regard to the 
Company's securities for the period from nine business days (or such other 
applicable period as Rule 10b-6 may provide) prior to such solicitation by 
the Underwriter of the exercise of Warrants until the later of the 
termination of such solicitation activity or the termination (by waiver or 
otherwise) of any right that the Underwriter may have to receive a fee for 
the exercise of Warrants following such solicitation. As a result, the 
Underwriter may be unable to provide a market for the Company's securities 
during certain periods while the Warrants are exercisable. Any temporary 
cessation of such market-making activities could have an adverse effect on 
the market price of the Company's securities. See "Underwriting." 

   Possible Delisting of Securities from the Nasdaq National Market.  While 
the Company's Units, the Common Stock and the Warrants meet the current 
Nasdaq National Market listing requirements and are expected to be initially 
included on the Nasdaq National Market, there can be no assurance that the 
Company will meet the criteria for continued listing. Continued inclusion on 
Nasdaq National Market generally requires that (i) the Company maintain at 
least $4,000,000 in "net tangible assets" (total assets less total 
liabilities and goodwill), (ii) the minimum bid price of the Common Stock be 
$1.00 per share, (iii) there be at least 100,000 shares in the public float 
valued at $1,000,000 or more, (iv) the Common Stock have at least two active 
market makers and (v) the Common Stock be held by at least 400 holders. 

   On November 6, 1996, the Nasdaq National Market proposed changes to the 
listing and maintenance requirements which, after a 30-day comment period and 
consideration of changes to the proposals, will be submitted to the 
Securities and Exchange Commission (the "Commission") for final approval. If 
the current proposal is approved without modification, the Company's 
qualification for continued listing on the Nasdaq National Market would 
require that (i) the Company maintain at least $4,000,000 in "net tangible 
assets," (ii) the minimum bid price of the Common Stock be $1.00 per share, 
(iii) there be at least 750,000 shares in the public float, valued at least 
$5,000,000 or more, (iv) the Common Stock have at least two active market 
makers and (v) the Common Stock be held by at least 400 holders. 

   If the Company is unable to satisfy the Nasdaq National Market's 
maintenance requirements, its securities may be delisted from the Nasdaq 
National Market. In such event, trading, if any, in the Units, the Common 
Stock and the Warrants would thereafter be conducted on the Nasdaq SmallCap 
Market, subject to meeting the requirements for listing on the Nasdaq 
SmallCap Market, or in the over-the-counter market in the so-called "pink 
sheets" or the NASD's "Electronic Bulletin Board." Consequently, the 
liquidity of the Company's securities could be impaired, not only in the 
number of securities which could be bought and sold, but also through delays 
in the timing of transactions, reduction in security analysts and the news 
media's coverage of the Company and lower prices for the Company's securities 
than might otherwise be attained. 

   Risks of Low-Priced Stock. If the Company's securities were delisted from 
Nasdaq National Market and could not be quoted on Nasdaq SmallCap Market (see 
"-- Possible Delisting of Securities from the Nasdaq National Market"), they 
could become subject to Rule 15g-9 under the Exchange Act, which imposes 
additional sales practice requirements on broker-dealers which sell such 
securities to persons other than established customers and "accredited 
investors" (generally, individuals with net worths in excess of $1,000,000 or 
annual incomes exceeding $200,000, or $300,000 together with their spouses). 
For transactions covered by this rule, a broker-dealer must make a special 
suitability determination for the purchaser and have received the purchaser's 
written consent to the transaction prior to sale. Consequently, such rule may 
adversely affect the ability of broker-dealers to sell the Company's 
securities and may adversely affect the ability of purchasers in this 
Offering to sell any of the securities acquired hereby in the secondary 
market. 

   Commission regulations define a "penny stock" to be, among others, any 
non-exchange listed equity security that has a Market Price (as therein 
defined) of less than $5.00 per share or with an exercise price of less than 

                                      20 
<PAGE>

$5.00 per share, subject to certain exceptions. For any transaction involving 
a penny stock, unless exempt, the rules require delivery, prior to any 
transaction in a penny stock, of a disclosure schedule prepared by the 
Commission relating to the penny stock market. Disclosure is also required to 
be made about commissions payable to both the broker-dealer and the 
registered representative and current quotations for the securities. Finally, 
monthly statements are required to be sent disclosing recent price 
information for the penny stock held in the account and information on the 
limited market in penny stocks. 

   The foregoing required penny stock restrictions will not apply to the 
Company's securities if such securities are quoted on the Nasdaq National 
Market or the Nasdaq SmallCap Market and have certain price and volume 
information provided on a current and continuing basis or meet certain 
minimum net tangible assets or average revenue criteria. There can be no 
assurance that the Company's securities will qualify for exemption from these 
restrictions. In any event, even if the Company's securities were exempt from 
such restrictions, it would remain subject to Section 15(b)(6) of the 
Exchange Act, which gives the Commission the authority to prohibit any person 
that is engaged in unlawful conduct while participating in a distribution of 
a penny stock from associating with a broker-dealer or participating in a 
distribution of a penny stock, if the Commission finds that such a 
restriction would be in the public interest. If the Company s securities were 
subject to the rules on penny stocks, the market liquidity for the Company's 
securities could be severely adversely affected. 

   Shares Eligible for Future Sale; Effect of Outstanding Options and 
Warrants. Future sales of Common Stock by existing stockholders pursuant to 
Rule 144 under the Securities Act could have an adverse effect on the price 
of the Company's securities. All of the 6,250,000 shares of Common Stock held 
by existing stockholders are eligible for sale under Rule 144 beginning in 
October 1998. Of the 6,250,000 shares of Common Stock outstanding, 500,000 
are Escrow Shares. Currently, 5,827,040 of the 6,250,000 shares of Common 
Stock outstanding are held by affiliates and will be subject to volume 
limitations after October 1998. In addition, the existing stockholders have 
agreed not to sell any shares of Common Stock for a period of two years from 
the date of this Prospectus without the prior written consent of the 
Underwriter. The Underwriter has demand and piggy-back registration rights 
covering the securities underlying the Unit Purchase Option and Vertical has 
demand and piggy-back registration rights covering the securities held by 
Vertical. Sales of Common Stock, or the possibility of such sales, in the 
public market may adversely affect the market price of the securities offered 
hereby. See "Shares Eligible for Future Sale." 

   Upon completion of this Offering, the Company will have outstanding (i) 
the Warrants to purchase an aggregate of 3,100,000 shares of Common Stock, 
(ii) the Investor Warrants to purchase 1,875,000 shares of Common Stock, 
(iii) the Stockholder Warrants to purchase 473,485 shares of Common Stock and 
(iv) Unit Purchase Options to purchase an aggregate of 620,000 shares of 
Common Stock, assuming exercise of the underlying Warrants. In addition, the 
Company has reserved for issuance 500,000 shares of Common Stock in 
connection with the 1996 Stock Option Plan, none of which have been granted. 
The existence of these securities could have an adverse effect on the price 
of the Company's outstanding securities. In addition, holders of such 
warrants and options are likely to exercise them when, in all likelihood, the 
Company could obtain additional capital on terms more favorable than those 
provided by the warrants and options. Further, while these warrants and 
options are outstanding, the Company's ability to obtain additional financing 
on favorable terms may be adversely affected. See "Description of Securities" 
and "Underwriting."

                               USE OF PROCEEDS 

   The net proceeds of this Offering to the Company, after deducting 
underwriting discounts and commissions and other estimated expenses of this 
Offering payable by the Company, are expected to be approximately $15.5 
million (approximately $18.0 million if the Underwriter's over-allotment 
option is exercised in full), assuming an initial public offering price of 
$6.00 per Unit. The Company intends to use the net proceeds as follows:

- ------ 
(1) Consist of loans in the aggregate amount of approximately $1.2 million 
    made to IAT AG by Volker Walther, a stockholder and a director of 
    Multimedia, during 1996 for working capital, bearing interest at 
    10% and maturing at the earlier of the consummation of this Offering or 
    June 30, 1997. 

(2) The 1,875,000 shares of Series A Preferred Stock of which 890,152 were 
    issued to Vertical, will automatically convert into Common Stock upon 
    consummation of this Offering and were issued on October 24, 1996. The 
    Series A Preferred Stock has an annual dividend of $.056 per share (equal 
    to a 7% dividend per annum on the purchase price of such shares). The 
    dividend payable on the Series A Preferred Stock is approximately $20,000 
    at December 31, 1996. 

(3) The Company will pay a $400,000 fee pursuant to the Marketing Agreement 
    to General Capital, an affiliate of Vertical, a stockholder of the 
    Company. See "Certain Transactions." 

   The foregoing represents the Company's best estimate of the allocation of 
the net proceeds of this Offering based on the current status of its 
business. Future events, including changes in competitive conditions and the 
status of the Company's business from time to time, may make changes in the 
allocation of the net proceeds of this Offering necessary or desirable. The 
Company anticipates that the remaining proceeds of this Offering will be 
sufficient to fund its operations through 1998. This estimate assumes 
substantial increases in the Company's sales and assumes the completion of 
the Company's third generation products and acceptance of these products in 
the multimedia communications market. There can be no assurance that the 
Company will be able to achieve such increased sales and failure to achieve 
such increase will require the Company to seek additional funding prior to 
1998. Pending application, the net proceeds will be invested in short-term, 
interest-bearing investments. Any proceeds received upon exercise of the 
Underwriter's over-allotment option or the Warrants will be added to working 
capital. See "Certain Transactions." 

   The Company continually evaluates potential strategic partners for additional
applications and broader marketing of technology. The Company may make a
participation or acquisition for strategic reasons. The Company has not
identified any participations or acquisition candidates in the United States or
elsewhere.

   A substantial part of the potential market for the Company's products are 
in the United States and entering into the United States market is a 
fundamental part of the Company's strategy. The Company intends to expand its 
marketing efforts, both by expanding its sales and marketing staff in Europe 
as well as establishing an office and a sales and marketing staff in the 
United States during 1997. 


                               DIVIDEND POLICY 


   The Company has never paid cash dividends on its Common Stock and does not 
anticipate or intend paying cash dividends in the foreseeable future on its 
Common Stock.

                                   DILUTION 


   At September 30, 1996, the net tangible book value of the Company was 
$(1,526,807) or $(.27) per share of Common Stock, after giving effect to the 
exchange for Common Stock of Multimedia and the issuance of 1,875,000 shares 
of Common Stock upon the conversion of the Series A preferred stock at the 
equivalent of $.80 per share. The net tangible book value per share 
represents the amount of the Company's total assets, less the amount of its 
intangible assets and liabilities, divided by the number of shares of Common 
Stock outstanding (exclusive of the Escrow Shares). After giving effect to 
(i) the sale of Units offered hereby (assuming no exercise of the 
Underwriter's Over-Allotment Option) at an assumed offering price of $6.00 
per unit (assuming no value is attributable to the Warrants included 
therein), (ii) after deducting the underwriting discounts and estimated 
expenses of the Offering, and (iii) the repayment of loans made by a 
stockholder of the Company in the amount of $1,182,000 (including loans 
received subsequent to September 30, 1996), the payment of $500,000 ($100,000 
of which was paid in October 1996) pursuant to the Marketing Agreement, and 
the issuance of 1,875,000 shares of Common Stock issuable upon the automatic 
conversion of all the outstanding shares of Series A Preferred Stock upon the 
consummation of this Offering, the net tangible book value of the Company as 
of September 30, 1996 would have been $14,015,193 or $1.58 per share. This 
represents an immediate increase in net tangible book value of $1.85 per 
share to existing stockholders and an immediate dilution in net tangible book 
value of $4.42 per share to new investors in this Offering. The following 
table illustrates this dilution on a per share basis:

                     SELECTED CONSOLIDATED FINANCIAL DATA 

   The following historical financial data, except for the information 
provided for the years ended December 31, 1991 and 1992, respectively and for 
the nine months ended September 30, 1995 and 1996, respectively, have been 
derived from the Consolidated Financial Statements. Consolidated Interim 
Financial Statements and the historical financial data for the years ended 
December 31, 1991 and 1992, respectively are unaudited, but in the opinion of 
the Company's management contain all adjustments, consisting only of normal 
recurring accruals, which are necessary for a fair presentation of the 
information included herein. Multimedia was formed in September 1996 as a 
holding company for the existing business of IAT AG and IAT Germany. 


   The pro forma consolidated balance sheet data reflect the issuance of 
Series A Preferred Stock in October 1996 and the conversion of the Series A 
Preferred Stock to 1,875,000 shares of Common Stock and the as adjusted 
consolidated balance sheet data reflect the Company's consolidated financial 
position as of September 30, 1996, giving effect to the sale of the Units 
offered hereby at an assumed price per Unit of $6.00 (assuming no exercise of 
the Underwriter's Over-Allotment Option) the application of the net proceeds 
therefrom, including the repayment of loans made by a stockholder of the 
Company in the amount of $1,182,000 (including loans received subsequent to 
September 30, 1996) from offering proceeds, the payment of $500,000 ($100,000 
of which was paid in October 1996) pursuant to the Marketing Agreement and 
the issuance of 1,875,000 shares of Common Stock issuable upon the automatic 
conversion of all of the outstanding shares of Series A Preferred Stock upon 
consummation of this Offering. The Company believes that the assumptions made 
with respect to such transactions provide a reasonable basis on which to 
present the financial information. 

   The following selected consolidated financial data is derived from, and 
should be read in conjunction with, the Consolidated Financial Statements of 
the Company and the related notes thereto included elsewhere in this 
Prospectus.

                   MANAGEMENT'S DISCUSSION AND ANALYSIS OF 
                FINANCIAL CONDITION AND RESULTS OF OPERATIONS 


   The following discussion of the consolidated financial condition and 
results of operations of the Company should be read in conjunction with the 
Consolidated Financial Statements and Notes to Consolidated Financial 
Statements included elsewhere in this Prospectus. This Prospectus contains 
forward-looking statements which involve risks and uncertainties. The 
Company's actual results may differ significantly from the results discussed 
in the forward-looking statements. Factors that might cause such a difference 
include, but are not limited to, those discussed in "Risk Factors." 

Overview 

   The Company develops, manufactures and markets customizable high quality 
visual communications systems for use in desktop computers which permit users 
to hold multi-point video conferences in two or more locations, as well as 
providing additional video, audio and data transfer features not available in 
traditional video conferencing systems. Unlike traditional video conferencing 
companies, the Company's focus is on high quality system solutions. The 
Company believes that the needs of its target customers cannot be addressed 
by currently available lower quality software-only products (including 
Internet products) or by high quality traditional video conferencing 
products. In addition to providing audio and video images of the other 
participants in the tele-conference, the Company's systems are also capable 
of simultaneously providing images and data in windows on the computer screen 
which can be viewed by all participants in the video conference and permit 
users at remote computer terminals to modify data and manipulate images 
through the operation of apparatus, such as microscopes and video cameras. 
These systems, which include both proprietary and third-party software and 
hardware, are inter-operable with products from certain vendors and comply 
with all relevant international standards, including H.320. The Company sells 
its systems and kits to end-users in a variety of industries and to OEMs and 
integrators. The Company has sold an aggregate of approximately 500 systems 
and kits, including pilot projects, since 1990. 

   The Company's technology has been developed with Strategic Partners, 
including DT, Texas Instruments, IBM Germany and Olympus. The Company 
believes that its technology can produce substantially higher quality image 
and video transmissions, including reduced noise and artifacts, truer color 
representation and higher frame rates, than other systems while using less of 
the computing power of the host desktop computer, which permits other 
applications to continue to operate without interruption. In addition, the 
Company's new generation of systems currently being developed is based on a 
programmable digital signal processor which provides flexibility for adapting 
to new algorithms, standards or user requirements. The Company believes that 
the high image quality and other features provided by the Company's systems 
will meet the requirements of various professional users including 
tele-medicine (i.e., transferring microscope, x-ray, video or other 
diagnostic images for evaluation by a physician at a remote site) and 
tele-surveillance (i.e., remote viewing and control of surveillance cameras 
and remote access control via switched networks). In excess of $22 million 
was invested in the Company by its stockholders and the Company has invested 
approximately $13 million in the research, development and marketing of this 
technology (including approximately $4 million in participations from the 
Company's Strategic Partners). This investment in the Company's technology 
does not include additional amounts invested directly by the Company's 
Strategic Partners in the development of their components used in the 
Company's systems. 

   The Company has developed two generations and is currently developing a 
third generation of its technology. The first generation was developed using 
a large number of computer boards and readily available components as the 
Company's initial entry in the visual communications field and to assess 
customer needs. The second generation, utilized in the Company's current 
systems, is characterized by a substantially reduced number of computer 
boards and improved capabilities. These systems use a combination of fully 
programmable digital signal processors and less-flexible hardwired 
processors. The second generation systems have inherently high prices per 
unit. For example, the Company's second generation MFKS Vision and Live 
systems have average prices of approximately $8,000 to $30,000 per system 
(depending on capabilities). Third generation systems, which the Company 
expects to begin shipping in 1997, utilize Texas Instruments' TMS320C80 
programmable digital signal processor (the "C8x") and are designed for 
commercial production with target sales prices of approximately $1,500 to 
$8,000 per system for corresponding MFKS systems. The Company believes that 
its third generation of systems will be its first systems which have the 
potential for widespread commercialization.

   The Company currently markets its products, both through its own sales staff
and through certain of its Strategic Partners, primarily in Europe. A
substantial part of the potential market for the Company's products are in the
United States and entering in the United States market is a fundamental part of
the Company's strategy. The Company intends to expand its marketing efforts,
both by expanding its sales and marketing staff in Europe as well as
establishing an office and a sales and marketing staff in the United States
during 1997. The Company continually evaluates potential strategic partners for
additional applications and broader marketing of IAT's technology. The Company
may make a participation or acquisition for strategic reasons. The Company's
results of operations will be dependent upon the Company's ability to market its
products in the United States, to launch its third generation of products on a
timely basis and to achieve market acceptance and penetration.

   The Company's revenues have quarterly fluctuations in which the fourth 
quarter has historically reflected the highest quarterly revenues, as a 
result of the perceived desire by its customers to deplete allocated budgets 
for the Company's products prior to the end of the calendar year. There can 
be no assurance that this trend will continue. Quarterly fluctuations depend 
in part on the timing of introduction of new products by the Company and its 
competitors. The Company expects its sales for the fourth quarter of 1996 not 
to be as high proportionately as in past years as the Company's customers 
await the release of the Company's third generation systems. 

   The Company anticipates the loss from operations for the fourth quarter of 
1996 to be equivalent to the average quarterly loss during the nine months 
period ended September 30, 1996. 

   Approximately 86%, 87%, 68% and 87% of the Company's revenues for the 
years ended December 31, 1993, 1994, 1995 and the nine months ended September 
30, 1996, respectively have been received from DT and its affiliates. The 
Company's volume of sales to DT and its affiliates has dropped in the third 
and fourth quarter of 1996 from the corresponding periods in the prior year 
as these customers awaited the release of the Company's third generation 
systems. The loss of sales or a significant reduction in sales to DT and its 
affiliates could have an adverse effect on the financial condition, results 
of operations and cash flows of the Company. 

   The Company's sales are made to customers principally in Switzerland and 
Germany with revenues created in Deutsche Marks and Swiss Francs. The 
Company's functional currency is the Swiss Franc. 

RESULTS OF OPERATIONS 

Nine Months ended September 30, 1996 and 1995 

   The average U.S. Dollar to Swiss Francs exchange rate was SF 1.20 = $1.00 
in the nine months ended September 30, 1996 as compared to SF 1.18 = $1.00 in 
the nine months ended September 30, 1995. 

   Revenues. The Company's revenues from the sale of multimedia systems products
for the nine months ended September 30, 1996 increased by approximately 25.1% to
$961,000 from $768,000 for the nine months ended September 30, 1995. The
increase in sales resulted primarily from an increase in the number of units
shipped partially offset by a decrease in unit sales price as the Company's
technology shifted and lower priced kits were introduced.

   Cost of sales. Cost of sales for the nine months ended September 30, 1996 
increased to $690,000 from $516,000 for the nine months ended September 30, 
1995. The cost of sales as a percentage of sales increased to 71.8% for the 
nine months ended September 30, 1996 from 67.2% for the nine months ended 
September 30, 1995. Although the Company realized savings from purchasing 
economies for the additional units produced, the savings were more than 
offset due to the aforementioned decrease in the unit sales price for the 
Company's products resulting in a higher cost of sales percentage in 1996. 

   Research and development costs. Research and development costs incurred 
decreased by approximately .7% to $1,952,000 for the nine months ended 
September 30, 1996 from $1,966,000 for the nine months ended September 30, 
1995. Although there was no significant change in these costs, the Company 
increased the number of employees involved in research and development to 
complete their third generation of products. The increased payroll costs 
resulting from the additional employees were offset by comparable decreases 
in the material and outside contracting costs during 1996. Participations 
received from Strategic Partners decreased to $272,000 for the nine months 
ended September 30, 1996 compared to $585,000 for the nine months ended 
September 30, 1995. The decrease in participations received was a result of 
the completion of certain development projects for DT. 


                                      28

   Selling expenses. Selling expenses increased by approximately 23.1% to 
$1,156,000 for the nine months ended September 30, 1996 from $939,000 for the 
nine months ended September 30, 1995. This is a result of an increase in the 
number of personnel in sales and marketing in an effort to create the demand 
for the Company's product as well as help expand the product base of 
applications for the Company's products. 

   General and administrative expenses. General and administrative expenses 
increased by approximately 1.1% to $1,042,000 for the nine months ended 
September 30, 1996 from $1,031,000 for the nine months ended in the year 
ended September 30. 1995. 

   Interest. Interest expense increased by approximately 51.1% to $139,000 
for the nine months ended September 30, 1996, from $92,000 for the nine 
months ended September 30, 1995, principally due to the increase in 
stockholder and bank loans. 

   Net Loss. Net loss for the nine months ended September 30, 1996 increased 
by approximately 18.1% to $3,733,000 from $3,162,000 for the nine months 
ended September 30, 1995. The loss increased as a result of the Company 
commencing the marketing of the third generation of its products and a 
decrease in research and development participations. 


YEARS ENDED DECEMBER 31, 1995 AND 1994 

   The average exchange rate for U.S. Dollars declined substantially as 
compared to the Swiss Franc by approximately 13.2% resulting in an increase 
in all revenue and expense accounts in 1995 by this same percentage. The 
average U.S. Dollar to Swiss Franc exchange rate was SF 1.18 = $1.00 in 1995 
as opposed to SF 1.36 = $1.00 in 1994. 

   Revenues. The Company's revenues for the year ended December 31, 1995 
increased by approximately 43.4% to $1,510,000 from $1,053,000 for the year 
ended December 31, 1994, an increase of $457,000. Approximately $139,000 of 
the increase was a result of the weakening of the U.S. Dollar against the 
Swiss Franc. The remaining increase of approximately $318,000 was primarily a 
result of an increase in the unit sales resulting from the introduction of 
the second generation of products. 

   Cost of sales. Cost of sales for the year ended December 31, 1995 
increased to $968,000 from $700,000 for the year ended December 31, 1994. The 
cost of sales as a percentage of sales decreased to 64.1% for the year ended 
December 31, 1995 from 66.4% for the year ended December 31, 1994 as a result 
of purchase price savings due to larger quantities purchased in 1995. 
Additionally the Company's fixed costs for plant and indirect labor and other 
costs decreased as a percentage of sales. 

   Research and development. The increase in research and development costs 
increased by approximately 11.5% to $2,531,000 for the year ended December 
31, 1995 from $2,269,000 for the year ended December 31, 1994. The increase 
was caused principally by the weakening in the U.S. Dollar versus the Swiss 
Franc. The number of personnel engaged in research activities during the two 
periods remained constant. Participations received decreased to $868,000 
during the year ended December 31, 1995 from $2,207,000 received for the year 
ended December 31, 1994 due to the lower number of projects in 1995 and the 
completion of certain large projects in 1994 with DT. 

   Selling expenses. Selling expenses increased by approximately 71.3% to 
$1,266,000 for the year ended December 31, 1995 from $739,000 for the year 
ended December 31, 1994, an increase of $527,000. Approximately $100,000 of 
this increase is due to the weakening of the U.S. Dollar compared to the 
Swiss Franc. The remainder of the increase was due to an increase in 
personnel costs, trade shows, advertising and other selling expenses. 

   General and administrative expenses. General and administrative expenses 
increased by approximately 72.0% to $1,374,000 for the year ended December 
31, 1995 from $799,000 for the year ended December 31, 1994, an increase of 
$575,000. Approximately $106,000 of this increase is a result of the 
weakening of the U.S. Dollar compared to the Swiss Franc. Personnel costs 
were increased by approximately $220,000 with the remaining increase 
resulting from an increase in professional fees, rents and other fixed costs 
in addition to an increase in the capital stock tax paid in Switzerland. 


                                      29 
<PAGE>


   Interest. Interest expense increased by approximately 3.2% to $129,000 for 
the year ended December 31, 1995 from $125,000 for the year ended December 
31, 1994, principally due to the increase in bank loans. 

   Net Loss. Net loss for the year ended December 31, 1995 increased by 
approximately 179.4% to $3,730,000 from $1,335,000 for the year ended 
December 31, 1994. The loss increased principally due to the decrease in 
research and development participations received in 1995, and the increase in 
the selling, general and administrative expenses previously discussed. 


YEARS ENDED DECEMBER 31, 1994 AND 1993 

   The average U.S. Dollar to Swiss Franc exchange rate was SF 1.36 = $1.00 
in 1994 as compared to SF 1.48 = $1.00 in 1993. 

   Revenues. Revenues decreased by approximately 46.4% to $1,053,000 for the 
year ended December 31, 1994 from $1,963,000 for the year ended December 31, 
1993, a decrease of $910,000. The decrease was due to a combination of less 
units sold as the Company was developing its second generation of products 
along with substantially lower unit selling prices in 1994 since the 
Company's products contained less hardware than in 1993. 

   Cost of Sales. Cost of sales for the year ended December 31, 1994 
decreased to $700,000 from $1,171,000 for the year ended December 31, 1993. 
The cost of sales as a percentage of sales increased to 66.4% for the year 
ended December 31, 1994 from 59.6% for the year ended December 31, 1993. The 
increase was a direct result of the fixed costs being a higher percentage of 
the lower sales volume. 

   Research and development. Research and development costs increased by 
approximately 24.1% to $2,269,000 for the year ending December 31, 1994 from 
$1,828,000 for the year ended December 31, 1993, an increase of $441,000. The 
increase was caused by the Company shifting their emphasis to research and 
development in 1994 to create new and improved products. At the same time the 
Company's participations received increased as a result of DT's demand for 
new projects. During 1994 the Company's participations received reached 
$2,207,000 as compared to $962,000 received in 1993. 

   Selling expenses. Selling expenses increased approximately 68.3% to 
$739,000 for the year ended December 31, 1994 from $439,000 for the year 
ended December 31, 1993, an increase of $300,000. The increase in selling 
expenses was a result of an increase in personnel costs of approximately 
$170,000, an increase in trade shows and advertising of approximately 
$80,000, and the balance of the increase due to other selling expenses 
including telephone, utilities and travel. 

   General and administrative expenses. General and administrative costs 
increased by approximately 6.0% to $799,000 for the year ended December 31, 
1994 from $754,000 for the year ended December 31, 1993. The increase was 
principally due to an increase in the capital stock tax paid to Switzerland. 

   Interest. Interest expense increased by approximately 78.6% to $125,000 
for the year ended December 31, 1994 from $70,000 for the year ended December 
31, 1993, principally due to the increase in notes payable banks. 

   Net Loss. Net loss for the year ended December 31, 1994 increased by 
approximately 0.8% to $1,335,000 from $1,324,000 for the year ended December 
31, 1993. 

INCOME TAXES 

   The Company, since inception, has not generated any taxable income. The 
Company accounts for income taxes under Statement of Financial Accounting 
Standards No. 109 ("FAS 109"). The Company has not realized any taxable 
income or loss in the United States through September 30, 1996. At September 
30, 1996 the Company has net operating loss carryforwards ("NOL") for Swiss 
and German income tax purposes of approximately $13,373,000 and $1,251,000 
respectively. The Swiss NOL's expire between 1996 and 2002, and the German 
NOL's have no expiration date.

LIQUIDITY AND CAPITAL RESOURCES 

   The Company had a working capital deficiency of $3,052,000 and a 
stockholders' deficiency of $2,855,000 at September 30, 1996. Net cash used 
in operations was $3,231,000 and $3,252,000 for the year ended December 31, 
1995 and the nine months ended September 30, 1996 respectively. The Company 
generated cash of $491,000 from the collection of trade receivables during 
the nine month period ended September 30, 1996 and used $280,000 for 
increased inventories. The Company's audited financial statements for the 
year ended December 31, 1995 contain an emphasis paragraph concerning the 
Company's ability to continue as a going concern. 

   Since inception, the Company's expenses have significantly exceeded its 
net sales, resulting in an accumulated deficit of $10,918,000 at September 
30, 1996. The Company has funded its operations since inception through the 
private placement of equity securities, loans from stockholders and research 
and development participations. Through September 30, 1996 the Company had 
raised approximately $14 million from private placements, including 
approximately $6 million of loans and capital previously restructured, $1.4 
million in stockholder loans and approximately $4.3 million in research and 
development participation agreements. Additionally, the Company generated 
capital through debt forgiveness from vendors of approximately $1.4 million 
in 1992. 

   IAT AG has a line of credit and two loans with a Swiss bank for approximately
$1,520,000 in the aggregate, bearing interest at 7% per annum and of which
approximately $1,446,000 is outstanding as of September 30, 1996. IAT Germany
has a line of credit with a German bank for approximately $700,000 which is
outstanding as of September 30, 1996. This loan bears interest at 10.5% per
annum. In November 1996, IAT Germany has received a conditional grant from the
Senate Administration for the Economy and Business of the State of Berlin,
Germany whereby IAT Germany will be reimbursed approximately $130,000 for
development costs to be incurred subsequent to September 30, 1996. In compliance
with the conditions of this grant, IAT Germany intends to locate facilities with
respect to its wavelet research in Berlin and to fund a portion of this research
with the proceeds of this grant.

   In October 1996, the Company received $1.5 million in connection with the 
Private Placement of the Series A Preferred Stock. In addition, in October 
and November 1996, the Company received loans from its stockholders 
aggregating $920,000, and repaid an existing loan of $120,000 to a company 
controlled by one of its principal stockholders. Research and development 
participations have declined, and are expected to continue at a reduced rate 
since the Company has developed the base technology for its third generation. 
Research and development expenses however, are expected to continue at the 
same rate in order to develop additional products and customized software 
which are expected to generate additional revenues for the Company. 

   The Company's expenditures are exceeding its revenues by approximately 
$400,000 per month, principally as a result of the continued research and 
development related to new products and operating losses, therefore, the $1.5 
million received upon the consummation of the Private Placement and the 
additional stockholder loans may only be sufficient to cover the Company's 
operations through January 1997. The Company intends to finance its research 
and development, expansion of marketing activities and working capital with 
the net proceeds of this Offering. Management believes that the proceeds of 
this Offering should be sufficient to fund the Company's operations and its 
working capital requirements due to the anticipated increased sales volume 
through 1998. The Company's ability to become profitable is dependent on the 
completion of the development of its third generation of products, a timely 
release of the products and market penetration. The Company may need to raise 
equity or debt financing. There can be no assurance that the Company will be 
able to raise such financing on acceptable terms, if at all. In addition, 
there can be no assurance that such financing will not be dilutive to the 
existing stockholders. Failure to raise capital when needed could have a 
material adverse effect on the financial condition and results of operations 
of the Company. 

ESCROW SHARES 

   The Company contemplates that the release of Escrow Shares, should it 
occur, will result in a substantial non-cash compensation charge to 
operations, based on the then fair market value of such shares. Such charge 
could substantially increase the Company's loss or reduce or eliminate the 
Company's net income, if any, for financial reporting purposes for the period 
during which shares are or become probable of being released from escrow. 
Although the amount of compensation expense recognized by the Company will 
not effect the Company's total stockholders equity, it may depress on the 
market price of the Company's securities. See "Principal Stockholders Escrow 
Shares."

                                   BUSINESS 

GENERAL 

   The Company develops, manufactures and markets customizable high quality 
visual communications systems for use in desktop computers which permit users 
to hold multi-point video conferences in two or more locations, as well as 
providing additional video, audio and data transfer features not available in 
traditional video conferencing systems. Unlike traditional video conferencing 
companies, the Company's focus is on high quality system solutions. The 
Company believes that the needs of its target customers cannot be addressed 
by currently available lower quality software-only products (including 
Internet products) or by high quality traditional video conferencing 
products. In addition to providing audio and video images of the other 
participants in the tele-conference, the Company's systems are also capable 
of simultaneously providing images and data in windows on the computer screen 
which can be viewed by all participants in the video conference and permit 
users at remote computer terminals to modify data and manipulate images 
through the operation of apparatus, such as microscopes and video cameras. 
These systems, which include both proprietary and third-party software and 
hardware, are inter-operable with products from certain vendors and comply 
with all relevant international standards, including H.320. The Company sells 
its systems and kits to end-users in a variety of industries and to OEMs and 
integrators. The Company has sold an aggregate of approximately 500 systems 
and kits, including pilot projects, since 1990. 

   The Company's technology has been developed with Strategic Partners, 
including DT, Texas Instruments, IBM Germany and Olympus. The Company 
believes that its technology can produce substantially higher quality image 
and video transmissions, including reduced noise and artifacts, truer color 
representation and higher frame rates, than other systems while using less of 
the computing power of the host desktop computer, which permits other 
applications to continue to operate without interruption. In addition, the 
Company's new generation of systems currently being developed is based on a 
programmable digital signal processor which provides flexibility for adapting 
to new algorithms, standards or user requirements. The Company believes that 
the high image quality and other features provided by the Company's systems 
will meet the requirements of various professional users including 
tele-medicine (i.e., transferring microscope, x-ray, video or other 
diagnostic images for evaluation by a physician at a remote site) and 
tele-surveillance (i.e., remote viewing and control of surveillance cameras 
and remote access control via switched networks). In excess of $22 million 
was invested in the Company by its stockholders and the Company has invested 
approximately $13 million in the research, development and marketing of its 
technology (including approximately $4 million in participations from the 
Company's Strategic Partners). This investment in the Company's technology 
does not include additional amounts invested directly by the Company's 
Strategic Partners in the development of their components used in the 
Company's systems. 

   The Company believes that the multimedia communications market will be 
divided between mass-market low quality software-only solutions and high 
quality system solutions which principally utilize hardwired processors. The 
Company believes that mass market solutions do not meet the needs of its 
potential customers because of the lower quality image and video 
transmissions and that hardwired processors are inflexible and difficult to 
adapt to new algorithms and standards. In addition, the Company believes that 
its use of programmable digital signal processors combined with its 
proprietary technology offers a competitive advantage over competitors using 
hardwired chips or software-only solutions. The Company is not aware of other 
companies which offer similar customized complete systems at comparable 
prices. 

   The Company has developed two generations and is currently developing a 
third generation of its technology. The first generation was developed using 
a large number of computer boards and readily available components as the 
Company's initial entry in the visual communications field and to assess 
customer needs. The second generation, utilized in the Company's current 
systems, is characterized by a substantially reduced number of computer 
boards and improved capabilities. These systems use a combination of fully 
programmable digital signal processors and less-flexible hardwired 
processors. The second generation systems have inherently high prices per 
unit. For example, the Company's second generation MFKS systems have average 
prices of approximately $8,000 to $30,000 per system (depending on 
capabilities). The Company's third generation systems, utilize Texas 
Instruments' C8x programmable digital signal processor and are designed for 
commercial production 

                                      32 

<PAGE>


with target sales prices of approximately $1,500 to $8,000 per system for 
corresponding MFKS systems. In 1996, the Company, partly in conjunction with 
its Strategic Partners, began marketing these third generation systems and 
expects to begin shipping them in 1997. The Company believes that its third 
generation of systems will be its first systems which have the potential for 
widespread commercialization. 

   The Company's existing products include the MFKS Vision and Live multi-
functional communications system and the MIKS Interactive Kiosk. MFKS is a 
high quality visual communications system which combines hardware and 
software for use in desktop computers and permits users to hold multi-point 
video conferences with simultaneous video, audio and data transfer. MIKS is 
an electronic kiosk system which allows consumers to access information 
stored in the electronic kiosk or in remote locations, including high quality 
video, while allowing instant contact to a video conference with a 
tele-consultant who has full access to the images and data seen by the 
consumer. 

   The Company's systems are flexible and can be configured in a variety of ways
to meet the requirements of specific customers. The Company, on a project by
project basis, designs systems which provide solutions on a customized basis for
the specific requirements of particular customers.


INDUSTRY 

   The driving force behind the growth of the video conferencing market was 
the desire to achieve the effectiveness of face-to-face meetings with the 
cost and convenience of the telephone. Video conferencing systems can improve 
worker productivity and reduce costs by eliminating or reducing travel, 
improving the timely exchange of information between dispersed work groups 
and leveraging the use of scarce personnel resources located at a distance 
from the person needing their expertise. Initial video conferencing products 
were relatively expensive and typically required dedicated, high speed 
transmission facilities, trained operators and special rooms, with customized 
lighting and acoustics, resulting in low demand. In recent years, however, 
the rapid growth and decreasing cost of world-wide switched digital telephone 
services, technological improvements in both audio and video quality and the 
availability of lower cost, easy to use turnkey communications systems have 
led to greater use of video conferencing. Historically, the multimedia 
communications market has been dominated by systems using hardwired 
processors. Today, desktop video conferencing systems using hardwired 
processors priced as low as $1,000 per unit have emerged. The Company 
believes, however, that such low cost systems provide lower quality video and 
still images and that, to reduce costs, many of such systems rely heavily on 
the host computer's CPU reducing the systems ability to simultaneously run 
other applications. Hardwired processors are inflexible and difficult to 
adapt to changes in technology, standards or customer needs. 

   In recent years international industry standards intended to facilitate 
interoperability among different vendors video conferencing systems without 
additional special equipment or arrangements have appeared including the 
current standard, H.320. While the implementation of emerging industry 
standards and other technological improvements have helped to increase sales 
of hardware-based video conferencing systems in recent years, the relatively 
high price and limited interoperability of these systems have impeded the 
widespread adoption of video conferencing as a mass communication medium. In 
an effort to expand the availability of video conferencing as a 
communications tool, a number of developers commenced efforts to develop 
software-based video conferencing technology that did not require expensive 
proprietary hardware. However, these systems often require intensive use of 
the desktop computer's CPU which limits the ability of the computer to 
simultaneously run other applications. For example, implementation of the 
full H.320 video conferencing standard using a software-only solution 
utilizing a Pentium CPU requires approximately 6 times the processing power 
of a common 150 MHz Pentium. In most of these systems, tradeoffs have 
been made to limit the demands on the CPU by keeping the picture size small 
and accepting lower picture clarity and frame rate. The Company expects that 
the mass market will be characterized by software bundled with operating 
systems offered by companies such as Microsoft which will be enhanced by 
shipments of desktop computers incorporating Intel's Pentium MMX software 
interface which offer improved video processing. 

   The Company believes that mass market solutions do not meet the needs of 
certain professional customers who demand better image clarity than is 
currently available using software-only products, such as doctors who will 
use visual communication systems to review microscope slides or other 
diagnostic images. Depending on the application, these customers may demand 
full-frame video, reduced noise and artifacts, truer color represen-


                                      33 
<PAGE>

tation and/or higher frame rates. In addition, many of these customers need 
solutions which allow for data sharing and full remote operation of 
applications. Software-only solutions require such a large portion of the 
CPU's processing capacity for video conferencing that they have difficulty in 
integrating these additional functions on their customers existing desktop 
computers. 

   In addition, many customers, especially OEMs and integrators, are 
concerned that their investment in visual communications technology will 
become obsolete. Systems using programmable digital signal processors, such 
as the C8x, may be attractive to OEMs and integrators because these systems 
are relatively easy to reprogram to handle new algorithms and standards as 
technology improves or to be customized to meet specialized customer needs. 
Hardwired chips have limited lives as upgrades or other changes require that 
a new chip be engineered and fabricated. Digital signal processors also 
substantially reduce the burden on the CPU of the host computer allowing 
other applications to run uninterrupted. 

STRATEGY 

   The Company intends to continue to jointly develop with its Strategic 
Partners innovative hardware and software alternatives to lower quality 
software-only products. The Company is in the process of completing 
development of its third generation of products and intends to continue to 
develop newer generations of its products as technology or the needs of its 
customers change. In addition, the Company seeks to identify new applications 
for its technology. 

   The Company's strategy of joint development with its Strategic Partners 
allows the Company to increase the effectiveness of its research and 
development by taking advantage of the knowledge and resources of its 
Strategic Partners (including skilled personnel, existing hardware and 
software libraries and participations) by eliminating unnecessary duplicative 
work and minimizing the Company's research and development expenditures. 

   The Company intends to target its technology and its products at the 
professional market, including customers using tele-medicine and 
tele-surveillance. The Company believes that these markets require high 
quality systems which provide solutions tailored to their requirements and 
contain higher quality image and video transmissions and other features than 
traditional video conferencing communications systems. The Company's systems 
are being designed to provide such high quality features and the Company 
intends to actively promote its products to this market. 

   The Company currently markets its products, both through its own sales staff
and through certain of its Strategic Partners, primarily in Europe. A
substantial part of the potential market for the Company's products are in the
United States and entering in the United States market is a fundamental part of
the Company's strategy. The Company intends to expand its marketing efforts,
both by expanding its sales and marketing staff in Europe as well as
establishing an office and a sales and marketing staff in the United States
during 1997. The Company continually evaluates potential strategic partners for
additional applications and broader marketing of IAT's technolgy. The Company
may make a participation or acquisition for strategic reasons.

   The Company's strategy will continue to follow a solution oriented 
approach. In many cases, potential customers of the Company's products will 
not need a standard system but will require a system designed specifically to 
meet their specific needs. The Company intends to continue developing, on a 
project by project basis, and in collaboration with its Strategic Partners, 
systems which provide solutions on a customized basis for the specific 
requirements of particular customers. See "Risk Factors -- Dependence Upon 
Agreements," "-- Further Developing Need for Additional Financing," "-- 
Developing Market," "-- Dependence on New Products and Rapidly Developing 
Technologies" and "-- Risk Associated with Expanded Operations in the United 
States." 

SYSTEMS 

   The Company's systems include both proprietary and third-party software 
and hardware, and are inter- operable with products from certain vendors and 
fully comply with all relevant international standards, including H.320. The 
software includes compression algorithms and routines to control 
video-conferencing, data transfer, transmission of still and moving video 
images, remote control of other applications and customizable features to 
meet the specific needs of customers. The hardware, consisting of a board or 
boards for insertion into 


                                      34 
<PAGE>


a host desktop computer includes a codec (a combination of a coder and 
decoder for compressing the number of bytes representing audio or video 
information and recovering the original bytes from the compressed bytes after 
they have been transmitted), a video inlay or overlay, a video switch and 
audio mixer. Compression algorithms and codecs reduce the number of bytes 
necessary to represent a specific piece of information in order to reduce the 
cost and time of transmitting data. However, the process of compression and 
decompression results in the loss of some of the original data and can 
introduce artifacts into the resulting image. The Company believes that its 
proprietary combination of software and hardware offer high image quality, 
including reduced noise and artifacts, truer color representation and high 
frame rates while still allowing simultaneous transmission of other data and 
audio signals. 

   The Company's systems are flexible and can be configured in a variety of 
ways to meet the requirements of specific customers. The Company, on a 
project by project basis, designs systems which provide solutions on a 
customized basis for the specific requirements of particular customers. The 
Company sells its systems and kits to end-users in a variety of industries 
and to OEMs and integrators. The Company's existing systems include the MFKS 
Vision and Live multifunctional communications system and the MIKS 
Interactive Kiosk.

   MKFS Vision and Live. The MFKS Vision and Live multifunctional 
communications system, allows simultaneous video, audio and data 
communications using the Company's software and hardware computer boards in 
IBM compatible standard desktop computers. The following shows the major 
elements of the MFKS Vision and Live system:

   IAT offers MFKS 128 and MFKS 384 systems which communicate at speeds of up 
to 128 kbps or up to 384 kbps, respectively, to match the communications 
needs of its customers. IAT developed its MFKS systems jointly with DT. The 
second generation of MFKS 128 consists of software, two computer boards (a 
codec and an ISDN (or other network) connection) and two optional computer 
boards and permits tele-conferencing and simultaneous full screen video with 
a PIP, audio and data communications on a desktop computer. IAT's MFKS 384 
systems consist of software and six to nine computer boards. MFKS 384 systems 
offer all of the features of MFKS 128 systems plus the ability to view two 
full-screen video windows simultaneously. The Company believes that its MFKS 
systems offer substantially higher image quality, including reduced noise and 
artifacts, truer color representation and higher frame rates, than 
software-only products. MFKS systems fully implement all current relevant 
international communications standards. While second generation MFKS systems 
used a combination of hardwired chips and programmable digital signal 
processors, IAT's third generation MFKS systems will exclusively use fully 
programmable C8x digital signal processors, communicate using widely 
available switched networks and are designed to work with ISDN or faster 
lines. Use of fully programmable digital signal processors allows easier 
upgrades and customization than systems using hardwired processors. The 
Company believes that the combination of the tele-conference and additional 
functions performed by its MFKS systems provide features not generally 
available in existing tele-conferencing systems and will meet the 
requirements of the professional users the Company intends to target. The 
following charts set forth the features and development of the Company's MFKS 
128 and MFKS 384 systems:

   MFKS systems can be customized to meet customer needs. The basic MFKS 
Vision & Live system can connect up to seven video sources including, 
microscopes, endoscopes, video cameras, document cameras, and laser disc 
players. It can display, send and receive images in two windows and grab 
(memorize single frames) in both the send and receive windows. In addition, 
the MFKS system allows for remote control of the remote computer and attached 
devices. MFKS systems can be configured with up to five ISDN or other 
high-speed connections (e.g. Ethernet LAN or T.1 telephone lines) to match 
customers' desired video imaging speed and resolution requirements. All MFKS 
systems have the ability to make multipoint and point to point connections. 

   The Company believes that the combination of the tele-conference and 
additional functions performed by its MFKS systems provide features required 
by professional users and not generally available in existing tele- 
conferencing systems. MFKS systems are currently used by DT for 
administrative tasks; by customers of DeTeSystems, an integrator and 
affiliate of DT, for a variety of tasks in different industries; by MAN 
Roland for tele-servicing of large, high-speed printing presses; by Grundig 
for tele-surveillance in an underground subway system; by the water quality 
control industry for visual water testing from remote sites; and by hospitals 
for pilot projects in tele-microscopy and tele-endoscopy. 

   The Company is jointly developing with Texas Instruments and DT its third 
generation MFKS system incorporating Texas Instrument's C8x programmable 
digital signal processor which will allow for easier upgrades than systems 
using hardwired chips. These new systems will provide all of the functions of 
the corresponding existing second generation systems at a substantially lower 
target prices. The third generation MFKS 128 uses a single proprietary 
computer board while the third generation MFKS 384 system shrinks the 
required hardware from six computer boards down to three. The Company expects 
to release the third generation of MFKS systems in 1997 at target prices of 
approximately $1,500 per system ($1,000 to OEMs in quantity) for the single 
board MFKS 128 system and approximately $8,000 per system ($3,500-$4,500 to 
OEMs depending on configuration) for the MFKS 384 system. The Company 
believes that the third generation of MFKS is the first system that it has 
manufactured which has the potential for market penetration. No assurance can 
be given that such systems will be introduced on a timely basis, if at all, 
or that such systems will be accepted by the market. See "Risk Factors -- 
Dependence on New Products and Rapidly Developing Technology." 

   The Company is presently working with Olympus to integrate MFKS systems 
into tele-microscopes. These products are expected to allow doctors in 
different locations to engage in a video conference while concurrently 
reviewing microscopic slides, and in some models, to remotely operate the 
microscope. The Company does not believe that the images from currently 
available visual communications systems provide sufficient image quality to 
transmit pictures of microscopic slides which would permit their use for 
diagnosis. The Company believes that the high quality images produced by the 
MFKS system offer images with resolutions and life-like colors sufficient for 
medical diagnoses. 

   Wavelet Compression. The Company is jointly developing with Professor 
Seiler of the Technical University of Berlin proprietary wavelet data 
compression technology which offers up to 300 to 1 compression with scalable 
data loss. The Company believes that the wavelet compression that it is 
developing will almost eliminate the time delay in viewing still images which 
are transmitted by visual communications systems and that this reduction will 
make the Company's MFKS systems more attractive. The Company believes that it 
will be able to offer wavelet compression in its MFKS systems beginning in 
1997 and that one of the first applications for this technology will be in 
the tele-microscopes being jointly developed with Olympus.

   MIKS Interactive Kiosk. The MIKS Interactive Kiosk was jointly developed 
with DT and IBM Germany. As shown below, the MIKS Interactive Kiosk consists 
of consumer electronic kiosks, tele-consultant stations, an authoring system 
and related proprietary software. 






                      [Schematic depicting elements of MIKS
                               Interactive Kiosk]






   Electronic Kiosks can present consumers with access to information stored 
in the electronic kiosk or in remote locations, including high quality video 
while allowing instant contact to a video conference with a tele-consultant 
who has full access to the images and data seen by the consumer. Routine 
inquiries can be handled by the stored information allowing each 
tele-consultant to service a number of electronic kiosks. The Company 
believes the MIKS Interactive Kiosk system can enable companies to more 
efficiently utilize their personnel and to rapidly collect market information 
on consumers using the electronic kiosks. 

   The MIKS Interactive Kiosk system also includes a proprietary database 
management system and an authoring system for electronic kiosks. An authoring 
system is, in effect, a sophisticated word processor which can also handle 
the development of menus and integration of audio and video data for the 
electronic kiosks. The Company's authoring system substantially reduces the 
cost and time to develop menus and pages for electronic kiosk displays. IAT 
may offer this authoring system to end-users and designers for use with other 
companies' electronic kiosk systems. The Company's proprietary database 
management system allows rapid and accurate updating of information stored in 
the electronic kiosks and collection of consumer data. The Company's existing 
second generation MIKS system requires two desktop computers per electronic 
kiosk and has an average price of approximately $45,000 per electronic kiosk. 
The Company has only installed pilot MIKS systems. 

   IAT and certain of its Strategic Partners are jointly developing the third
generation MIKS Interactive Kiosk system which will reduce the hardware demands
to only one desktop computer with two proprietary computer boards per electronic
kiosk. The Company's target price for the third generation MIKS system is
approximately $20,000 per electronic kiosk. IAT expects to begin selling third
generation MIKS systems in 1997, but no assurance can be given that such systems
will be introduced on a timely basis, if at all, or that such systems will be
accepted by the market. See "Risk Factors -- Dependence on New Products and
Rapidly Developing Technology."

   OEM. In addition to complete systems, the Company offers OEMs and 
integrators MFKS kits utilizing its existing second generation technology and 
expects to begin offering kits utilizing its third generation technology in 
1997. OEMs and integrators install the Company's hardware and software in 
their own systems. In addition to the MFKS kits described in the following 
table, the Company also offers MIKS kits.

   The Company expects that a majority of its sales will come from OEMs and 
integrators. The Company's sales will therefore be dependent on the sales 
efforts of third parties which it cannot control. There can be no assurance 
that such systems will be introduced on a timely basis, if at all, or that 
such systems will be accepted by the market. 

STRATEGIC PARTNERS 

   The Company's Strategic Partners have played an important role in the 
development of the Company's technology and products and in some cases, have 
been substantial customers of the Company's products. See "Risk Factors -- 
Dependence on Agreements" and "Business -- Customers." 


                                      41 
<PAGE>


   The Company and its Strategic Partners have conducted the research and 
development of the Company's products pursuant to various contracts. Once 
development of the Company's products is complete, it will enter into 
marketing agreements with the relevant Strategic Partners. Cooperation with 
its strategic partners enables the Company to take advantage of its partners' 
knowledge, technology and resources. 

   Deutsche Telekom. DT is the Company's oldest Strategic Partner with a 
relationship extending back to 1992. The Company and DT jointly developed and 
contributed $3.1 million and $2.5 million, respectively, to the first and 
second generations of the MFKS Vision and Live systems. The Company and DT 
each have the right to market the MFKS Vision and Live Systems and other uses 
of the technology developed in connection with this product. Approximately 
86%, 87%, 68% and 87% of the Company's revenues for the years ended December 
31, 1993, 1994 and 1995 and the nine months ended September 30, 1996, 
respectively have been received from DT and its affiliates. The Company 
continues to work with DT to develop parts of the third generation of MFKS 
Vision and Live. 

   IBM Germany and Deutsche Telekom. The Company and DT made a strategic 
alliance with IBM Germany to develop the MIKS Interactive Kiosk by expanding 
the MFKS technology. Since the beginning of the development of the MIKS 
Interactive Kiosk, the parties have each contributed one-third to the total 
of research and development costs of $4.0 million. Currently, the partners 
cooperate informally to supply components for new MIKS systems which can be 
sold by any partner. The partners are negotiating a marketing agreement to 
formalize this arrangement. 

   Texas Instruments. The Company is jointly developing base hardware and
software with Texas Instruments for its third generation MFKS Vision and Live
system incorporating the C8x chip. The Company believes that the C8x chip offers
the best price to value ratio for the demanding high quality multimedia systems
it builds for its customers in all of its markets. The Company expects that it
will continue to work with Texas Instruments to expand the range of the
Company's products utilizing the C8x. The Company expects that it will launch
the single board version of MFKS Vision and Live during 1997. Both parties have
the right to sell and license the board. TI and IAT are in negotiations to
define the role of each partner in marketing and supporting products based on
the C8x and supporting customers working on C8x products (OEMs). See "Risk
Factors -- Suppliers."

   Olympus. In 1995, the Company began to collaborate with Olympus to combine 
its MFKS Vision and Live technology with Olympus' expertise in microscopes to 
produce systems for tele-microscopy and tele-endoscopy. Each of the Company 
and Olympus have contributed to the development of these specialized systems. 
Olympus will use its position in the microscopy business to market the MFKS 
based tele-microscopy system jointly with the Company. To further enhance the 
capabilities of the products developed with Olympus, the Company is jointly 
developing wavelet compression technology with Dr. Seiler of the Technical 
University of Berlin. See "Business -- Systems -- MFKS Multifunctional 
Communications Systems -- Wavelet Compression." 


RESEARCH AND DEVELOPMENT 

   The Company believes that research and development is vital to the success 
of its business and intends to continue, and to devote substantial resources 
to, its research and development efforts to improve its products and adapt to 
the changing environment and the demands of its customers. 


   The Company's strategy of joint development with its Strategic Partners 
allows the Company to increase the effectiveness of its research and 
development by taking advantage of the knowledge and resources of its 
Strategic Partners (including skilled personnel, existing hardware and 
software libraries and participations) by eliminating unnecessary duplicative 
work and minimizing the Company's research and development expenditures. The 
Company's technology has been developed with Strategic Partners, including 
DT, Texas Instruments, IBM Germany and Olympus. In excess of $22 million was 
invested in the Company by its stockholders and the Company has invested 
approximately $13 million in the research, development and marketing of its  
technology (including approximately $4 million in participations from the 
Company's Strategic Partners). This investment in the Company's technology 
does not include additional amounts invested directly by the Company's 
Strategic Partners in the development of their components used in the 
Company's systems. 


                                      42 
<PAGE>


   To date, the Company has generally focused first on developing systems 
which can be utilized by customers in the field to assess the needs of such 
customers. IAT and its Strategic Partners have then refined these systems and 
tried to reduce costs while continuing to upgrade the systems to take into 
account changes in standards and technology. In addition, a key function with 
development of a proprietary library of processing algorithms which can be 
adapted to a variety of platforms. IAT is jointly developing with Texas 
Instruments and DT its third generation of technology with the functionality 
of the second generation systems plus additional features at a substantially 
lower price. The Company views its third generation products as the first 
products that it has produced that have the potential for market penetration. 
Once IAT's third generation products are introduced, the Company's research 
emphasis will shift from basic research and initial product development to 
improvements in the Company's systems to meet the needs of specific customers 
or groups of customers and to take into account advances in technology or 
standards. However, IAT expects to continue to conducts research and 
development jointly with its Strategic Partners who contribute to the costs 
of research and development. "Risk Factors -- Dependence on New Products and 
Rapidly Developing Technologies." 

   The Company is currently working with Olympus to integrate MFKS systems 
into tele-microscopes and is jointly developing wavelet compression 
technology with Professor Seiler of the Technical University of Berlin. See 
"--Systems -- MFKS Vision and Live -- Wavelet Compression." 

   The Company is working to develop versions of MFKS systems and MIKS 
Interactive Kiosks available as pure software products to take advantage of 
Intel's Pentium MMX software interface. In addition, the Company is 
conducting research on applying its technology to digital television area as 
well as providing intranet capabilities for its systems. There can be no 
assurance that the Company will be able to develop its business in these 
areas, if at all. 

MARKETING 

   The Company targets professional users who need the highest available 
communications quality for demanding applications such as tele-medicine and 
tele-surveillance. The Company believes that the needs of its target 
customers cannot be addressed by currently available lower quality 
software-only products (including Internet products) or by high quality 
traditional video conferencing products. Depending on the application, these 
customers may demand full frame video, reduced noise and artifacts, truer 
color representation and/or higher frame rates. In addition, many of these 
customers need solutions which allow for data sharing and full remote 
operation of applications. The Company believes that its proprietary know-how 
for combining hardware and software solutions in complete systems is unique. 
The Company believes that its technology can produce substantially higher 
quality image and video transmissions than other systems while using less of 
the computing power of the general purpose CPU of the host desktop computer, 
which permits other applications to continue to operate without interruption. 

   In addition, IAT targets OEMs and integrators and offers these customers 
products with a range of compatibilities and prices. See "-- OEM." The 
Company's use of programmable digital signal processors and proprietary 
software offers full implementation of relevant standards and allows these 
companies to preserve their investment in visual communications technology. 
Systems using programmable digital signal processors, such as the C8x used in 
the Company's third-generation systems, are attractive to OEMs and 
integrators because these systems are relatively easy to reprogram to handle 
new algorithms and standards as technology improves or to be customized to 
meet specialized customer needs. Hardwired chips are not as flexible as 
programmable digital signal processors as upgrades or other changes require 
that a new chip be engineered and fabricated. 

   The Company currently markets its products, both through its own sales staff
and through certain of its Strategic Partners, primarily in Europe. IAT's sales
and marketing force of 10 persons is located primarily in Germany. A substantial
part of the potential market for the Company's products are in the United States
and entering into the United States market is a fundamental part of the
Company's strategy. The Company intends to expand its marketing efforts, both by
expanding its sales and marketing staff in Europe as well as establishing an
office and a sales and marketing staff in the United States during 1997. The
Company continually evaluates potential strategic partners for additional
applications and broader marketing of IAT's technology. The Company may make a
participation or acquisition for strategic reasons. Once development of the
Company's products is complete, it


                                      43 
<PAGE>

may enter into marketing agreements with the relevant Srategic Partners. IAT 
contacts customers via its sales force, web site, articles, advertising, and 
through certain of its Strategic Partners. In several cases the Company has
supplied MIKS Interactive Kiosks to fairs and exhibitions to gain customer
exposure. 

   Currently, purchase decision cycles for the Company's products are relatively
long because the technology is new and costs are relatively high. New customers
typically acquire a pilot system or systems to evaluate before purchasing a
number of systems. While the Company sells these pilot units in most cases, it
may lend evaluation units to certain accounts. In many cases, the customer
requires the approval of its senior management or the board of directors before
purchasing a number of the Company's systems. The Company is not aware of other
companies which offer similar customized complete systems at comparable prices.
The Company believes that the market for high end systems will expand and
purchase decision cycles will shorten once the price of introductory systems
decrease. Currently, the target price of a third generation MFKS system is
approximately $1,500 per unit and the Company has targeted a $1,000 per unit
price for a third-generation OEM kit. There can be no assurances whether or not
the Company will achieve such target prices.


CUSTOMERS 

   The Company believes that there are numerous potential uses by 
professional users for its MFKS systems. MFKS systems are currently used by 
DT for administrative tasks; by customers of DeTeSystems, an integrator and 
affiliate of DT, for a variety of tasks in different industries; by MAN 
Roland for tele-servicing of large, high-speed printing presses; by Grundig 
for tele-surveillance in an underground subway system; by the water quality 
control industry for visual water testing from remote sites; and by hospitals 
for pilot projects in tele- microscopy and tele-endoscopy. The following 
table sets forth certain of the Company's customers and their respective 
industries: 

DT and DeTeSystem  ........         Telecom  and Integrator 
MAN Roland  ...............         Printing  Presses 
Olympus  ..................         Medical, Scientific and Industrial Devices 
Grundig  ..................         Tele-surveillance 
Kantonspolizei Zurich  ....         Police Department of Zurich, Switzerland 

   Approximately 86%, 87%, 68% and 87% of the Company's revenues for the 
years ended December 31, 1993, 1994 and 1995 and the nine months ended 
September 30, 1996, respectively have been received from DT and its 
affiliates. The loss of sales or a significant reduction in sales to DT could 
have a material adverse effect on the Company's business, financial condition 
and result of operations. There can be no assurance that any of the customers 
listed above will continue to purchase products from the Company in the 
future. 

INTELLECTUAL PROPERTY 

   The Company's success is heavily dependent upon its proprietary 
technology. The Company currently has no patents and relies primarily on 
copyright, trademark and trade secrets law, as well as employee and third- 
party non-disclosure agreements, to protect its intellectual property. There 
can be no assurance that the steps taken by the Company to protect its 
proprietary rights will be adequate to prevent misappropriation of its 
technology or independent development by others of similar technology. 

   In addition, the laws of some foreign countries do not protect the 
Company's proprietary rights to the same extent as do laws in the United 
States. There can be no assurance that the protections afforded by the laws 
of such countries will be adequate to protect the Company's proprietary 
rights, the unenforceability of any of which could have a material adverse 
effect on the Company's business, financial condition and results of 
operations. 

   Litigation may be necessary to enforce the Company's intellectual property 
rights or to protect the Company's trade secrets. There can be no assurance 
that any such litigation would be successful. Any such litigation, even if 
successful, could result in substantial costs and diversion of resources and 
could have a material adverse effect on the Company's business, financial 
condition and results of operations. 

   The Company has not been charged with infringement of any proprietary 
rights of others; however, there can be no assurance that third parties will 
not assert infringement and other claims against the Company or that 


                                      44 
<PAGE>


such claims will not be successful. From time to time, the Company may 
receive in the future notice of claims of infringement of other parties' 
proprietary rights. Many participants in the Company's industry have an 
increasing number of patents and have frequently demonstrated a readiness to 
commence litigation based on allegations of patent or other intellectual 
property infringement. Third parties may assert exclusive patent, trademark, 
copyright and other intellectual property rights to technologies that are 
important to the Company. There can be no assurance that infringement (or 
claims for indemnification resulting from infringement claims) will not be 
asserted or prosecuted against the Company or that any such assertion or 
prosecution will not have a material adverse effect on the Company's 
business, financial condition or results of operations. Regardless of the 
validity or the successful assertion of any such claims, the Company could 
incur significant costs and diversion of resources in defending such claims, 
which could have a material adverse effect on the Company's business, 
financial condition and results of operations. Furthermore, any party making 
such claims could secure a judgment awarding substantial damages, as well as 
injunctive or other equitable relief, which could effectively block the 
Company's ability to make, use, sell, distribute or market its products and 
services in the United States or abroad. Any such judgment could have a 
material adverse effect on the Company's business, financial condition and 
results of operations. In circumstances where claims relating to proprietary 
technology or information are asserted against the Company, the Company may 
seek licenses to such intellectual property. There can be no assurance, 
however, that such licenses would be available or, if available, that such 
licenses could be obtained on terms that are commercially reasonable and 
acceptable to the Company. The failure to obtain the necessary licenses or 
other rights could preclude the sale, manufacture or distribution of the 
Company's products and, therefore, could have a material adverse effect on 
the Company's business, financial condition and results of operations. 

   The Company believes its MFKS Vision and Live and MIKS Kiosk trademarks are
important to the development of its business and will attempt to register them
as trademarks in the United States, Germany and elsewhere. The Company intends
to vigorously protect its trademarks.

COMPETITION 

   The visual communications business is highly competitive. The Company 
estimates that more than 100 companies world-wide offer products which 
compete in its market segments and expects that whether or not the Company is 
successful in capturing market share, the competition will intensify in the 
future. The Company believes that the majority of its competitors focus on 
low-cost products or closed device solutions such as video phones. The 
Company believes that the principal competitive factors in the visual 
communications industry are price, video and audio quality, the ability to 
connect auxiliary devices such as video disk players, reliability, service 
and support, and vendor and product reputation. The Company believes that its 
ability to compete successfully will depend on a number of factors both 
within and outside its control, including the adoption and evolution of 
industry standards, the pricing policies of its competitors and suppliers, 
the timing of the introduction of new hardware and software systems and 
services by the Company and others, the Company's ability to hire and retain 
employees, and industry and general economic trends. The Company anticipates 
that in the near future the visual communications market will continue to 
polarize with certain providers focusing on capturing the mass consumer 
market with lower quality and less costly software-only products or products 
based on hardwired chips while the Company will continue to seek to provide 
hardware and software systems for a more specialized and dedicated market. 
The Company intends to market its technology and its products to professional 
customers who are not currently utilizing video conferencing communications 
systems. If the market for these products is established, competitors of the 
Company may begin to manufacture products similar to the Company's products. 
In addition, while the Company believes it has created proprietary technology 
and advantages in manufacturing its products and that a competitor would 
require significant investment and the efforts of a highly skilled team, there 
are no barriers restricting competitors from entering into the market in 
which the Company's intends to sell its products. While the Company believes 
the mass market solutions do not meet the needs of its customers, the 
availability of these products may have an adverse effect on the pricing of 
the Company's products. 

   Many of the Company's current and potential competitors, have 
significantly longer operating histories and/or significantly greater 
managerial, financial, marketing, technical and other competitive resources, 
as well as greater name recognition, than the Company. As a result, the 
Company's competitors may be able to adapt more quickly to new or emerging 
technologies and changes in customer requirements and may be able to devote 

                                      45
<PAGE>

greater resources to the promotion and sale of their products and services. 
There can be no assurance that the Company will be able to compete 
successfully with existing or new competitors. In addition, competition could 
increase if new companies enter the market or if existing competitors expand 
their service offerings. An increase in competition could result in material 
price reductions or loss of market share by the Company and could have a 
material adverse effect on the Company's business, financial condition and 
results of operations. 

   To remain competitive, the Company will need to continue to invest in 
research and development and sales and marketing. There can be no assurance 
that the Company will have sufficient resources to make such investments or 
that the Company will be able to make the technological advances necessary to 
remain competitive. In addition, current and potential competitors have 
established or may in the future establish collaborative relationships among 
themselves or with third parties, including the Company's Strategic Partners, 
to increase the visibility and utility of their products and services. 
Accordingly, it is possible that new competitors or alliances may emerge and 
rapidly acquire significant market shares. Such an eventuality could have a 
material adverse effect on the Company's business, financial condition and 
results of operations. 


SUPPLIERS AND PRODUCTION 

   The Company does not have supply contacts with any of its vendors and 
purchases are made with purchase orders. Certain critical components and 
parts used in the Company's systems, including the C8x, are procured from a 
single source. The Company believes that the C8x will substantially decrease 
the cost of the hardware the Company uses in its third generation products 
and is necessary to permit the Company's systems to be sold at prices which 
create the potential for market penetration. The C8x is only manufactured by 
Texas Instruments and the Company does not have any other source for 
obtaining a programmable digital signal processor which would provide the 
Company with the same functions at a similar price. The Company obtains other 
parts and certain components only from a single supplier of such parts or 
components, even where multiple sources are available, to maintain quality 
control and enhance the working relationship with suppliers. There can be no 
assurance that the Company will be able to continue to obtain these parts 
from these sources or that it can obtain alternatives from other terms on 
terms acceptable to the Company. Any interruption in the supply of such parts 
could have a short-term material adverse effect on the business and results 
of operations of the Company. 

   The Company relies on third-party manufacturers located in Germany, 
Switzerland and Finland to produce its products. To insure the quality of the 
Company's systems, all of the Company's manufacturers have the demanding ISO 
9000 quality certification. The Company contracts with such suppliers to 
manufacture batches of products and does not have long-term contracts with 
these companies. These manufacturers supply services to a variety of other 
companies some of whom may be competitors of the Company. IAT's current 
manufacturers specialize in relatively small batches of products. If the 
Company's sales increase, it will have to examine the possibility of using 
other manufacturers who specialize in larger batches. There can be no 
assurance that the Company will be able to continue to obtain the services of 
its existing manufacturers on terms acceptable to the Company or that it can 
obtain alternatives from other terms on terms acceptable to the Company. Any 
interruption in the supply of such parts could have a short-term material 
adverse effect on the business and results of operations of the Company. 
However, over the space of one to two quarters the Company believes that it 
could identify and qualify alternate parts, with the except of C8x chips. 
Over a longer-term the Company believes it could re-engineer its products to 
use alternate parts. 

AGREEMENTS WITH STRATEGIC PARTNERS 

   Texas Instruments. The Company's relationship with Texas Instruments is 
evidenced by, among others, the MVP Cross License Agreement (the "MVP Cross 
License Agreement") between IAT AG and Application Specific Product Group of 
Texas Instruments France in 1994. The MVP Cross License Agreement expires in 
2004 and can be extended for one year periods by written agreement. Pursuant 
to the MVP Cross License Agreement, the Company was granted a worldwide, 
non-transferable, non-assignable, non-exclusive, fully paid license to use, 
modify, compile or otherwise develop as applicable certain software programs 
relating to encoding and decoding pursuant to H.320, JPEG, H.261, G.728 and 
G.722 standards and to make, have made, use, sell or otherwise dispose of 
hardware and software products incorporating object code versions of such 
software programs. Texas Instruments was granted a worldwide, 
non-transferable, non-assignable, non-exclusive, fully paid license 

                                      46 

<PAGE>


to use, modify, compile or otherwise develop as applicable certain software 
programs relating to encoding and decoding pursuant to H.221, H.242, H.230 
standards and to make, have made, use, sell or otherwise dispose of hardware 
and software products incorporating object code versions of such software 
programs. The Company has the obligation to keep the source code of these 
programs confidential but may sublicense these programs provided that it 
enters into a sublicense agreement on substantially the same terms as the MVP 
Cross License Agreement. Either party to the MVP Cross License Agreement may 
terminate this agreement upon written notice upon the occurrence of certain 
events of default including the other party having a substantial change in 
ownership such as to create a material conflict of interest. 

   On June 12, 1996, IAT AG and Texas Instruments entered into the Joint 
Development and Cross License Agreement (the "Texas Instruments Agreement") 
to reflect the changes in technology and to determine the parties rights and 
obligations in light thereof. Pursuant to the Texas Instruments Agreement, 
which expires on April 1, 1999, Texas Instruments and IAT AG agreed to 
develop or acquire and deliver software and hardware products to each other 
and to provide engineering support to each other. Subject to completing its 
obligations, IAT AG is to receive a non-transferable, non-assignable, 
non-exclusive license under Texas Instruments' copyrights and associated 
trade secrets, solely to use, modify, compile or otherwise develop as 
applicable software programs to provide quality Windows 95 video conferencing 
implementation for personal computers and to make, have made, use and 
sublicense use of object code versions of such software programs solely for 
operation on the C8x. The license is fully paid except for T.123 Databeam 
software which is royalty bearing and for which Texas Instruments negotiates 
the royalty payable by IAT on a case by case basis and on a most favored 
nations status. IAT AG may sublicense the programs it develops jointly with 
Texas Instruments pursuant to the Texas Instruments Agreement but has the 
obligation to keep the source code confidential. If Texas Instruments 
licenses the use of its H.320 software library to a third party, it will pay 
IAT AG the greater of 50% of the license fee or $20,000, provided, however, 
that if Texas Instruments grants licenses to existing users of IAT AG's 
systems, no royalty will be due to IAT AG. If Texas Instruments licenses to 
third parties the use of the reference design produced by IAT AG, Texas 
Instruments will pay IAT AG the greater of 35% of the license fee or $7,000. 
If Texas Instruments sells evaluator kits defined as bundled hardware and 
software as produced by IAT, Texas Instruments has to pay to IAT 10% of the 
kit fee provided, however, that Texas Instruments has the right to provide 
the kit without the fee or without separately identifying fees and in such 
event no fees are due to IAT AG. The Texas Instruments Agreement may be 
terminated by either party upon the same terms and conditions as stated in 
the MVP Cross License Agreement described above. 

   Deutsche Telekom. In December 1992, IAT Germany and DT entered into the 
Contract of the Communication Computer Development Community (the 
"Development Agreement") to jointly develop software for MFKS on commercially 
available boards. IAT Germany and DT were responsible for equal parts of the 
development cost of these components which were used in first and second 
generations of the MFKS system. The agreement provided that upon full 
development of the components, the parties would enter into a licensing 
agreement setting forth the rights to the jointly developed intellectual 
property. 

   In March 1994, IAT AG and DT entered into a Licensing and General 
Distribution Agreement (the "DT Licensing Agreement") which provides for a 
framework within which both parties will endeavor to jointly launch and 
exploit products developed pursuant to the Development Agreement. The DT 
Licensing Agreement has an unspecified duration and may be terminated upon 
breach by either party. Each party has the right to grant sublicenses upon 
receipt of consent to the other party. If one party decides not to 
participate in the joint exploitation of products, the other party shall be 
given the possibility to exploit the product on its own. The DT Licensing 
Agreement was intended to provide a framework within which to develop 
products, and royalty payments are to be determined by the parties in the 
future. 

   In October 1995, IAT AG and DT entered into the General Cooperation 
Agreement Concerning Joint Further Development of IAT/Deutsche Telekom 
Software Codec on the Basis of the Texas Instruments Parallel Processor 
TMS320C8x (the "DT Cooperation Agreement"). The DT Cooperation Agreement 
expires on December 31, 1996 and is the subject of extension negotiations. It 
provides that the prototype of the codec developed pursuant to the 
Development Agreement will be further refined and integrated with the C8x. 
Each partner to the DT Cooperation Agreement bears the cost of the research 
and development. To date, each partner has contributed $1.0 million to the 
cost of research and development. The DT Cooperation Agreement further 
provides that IAT 

                                      47 
<PAGE>

AG transfers to DT all of its rights and obligations under the MVP Cross 
License Agreement. Each party has the right to terminate the DT Cooperation 
Agreement in whole or in part upon written notice if the other party does not 
pursue the goals described in the DT Cooperation Agreement, the cost 
projections provided for in the DT Cooperation Agreement are exceeded and the 
completion deadlines are not met. 

   IBM Deutschland Informationssysteme GmbH and Deutsche Telekom. In December 
1994, IAT AG, DT and IBM Germany entered into the Cooperation Contract 
Covering the Development of Version 3 of the Multimedia Information and 
Communication System MIKS (the "MIKS Agreement"). The MIKS Agreement 
supersedes agreements between IAT AG, DT and IBM Germany with respect to 
versions 1 and 2 of the MIKS Interactive Kiosk and expires on December 30, 
1996. The Company believes the goals of the MIKS Agreement have been achieved 
and does not intend to extend the agreement. The MIKS Agreement provides that 
IAT AG, DT and IBM Germany will jointly develop the MIKS Interactive Kiosk as 
a dual-board solution with each partner bearing one-third of the expenses of 
this development. Pursuant to the MIKS Agreement, each party has the right to 
use the jointly developed components and parts for their own use, to sell to 
third parties for their internal usage and to allow third parties to utilize 
components and parts for marketing as resellers. The MIKS Agreement provides 
for the collection of royalties in the amount of 3,000 Deutsche Marks for 
each component and nine (9%) percent of the sales per part used outside the 
MIKS Interactive Kiosk. Each party is to receive one- third of the royalties 
until the development costs have been recovered. The Company believes it is 
possible that it may enter into a new agreement with DT and IBM Germany with 
respect to MIKS but no assurance can be given that such an agreement will be 
entered into on terms favorable to the Company, if at all. 

   Olympus Optical Co. (Europe) GmbH. In March 1996, IAT Germany entered into 
a Cooperation Agreement with Olympus pursuant to which IAT Germany agreed to 
provide Olympus with IAT Germany's resale price list and to allow Olympus to 
resell IAT Germany's products to its customers. In addition, IAT Germany may 
procure Olympus microscopes, including any and all accessories, at a resale 
discount of 20% of the retail cost. IAT Germany and Olympus agree to provide 
initial training for their respective employees in the use of their products 
and to consider a long-term partnership. 

EMPLOYEES 

   As of November 30, 1996, the Company had a total of 52 full-time employees 
of which 36 and 16 are located in Germany and in Switzerland respectively. Of 
these employees, 33 are employed in engineering and product development, 10 
in sales and marketing, and 9 in managerial and administrative functions. The 
Company's employees are not party to any collective bargaining agreements or 
labor unions. The Company has not experienced any work stoppages and believes 
that its relations with its employees are good. 

PROPERTY 

   The Company does not own but leases approximately 6500 square feet of 
office space and approximately 350 square feet of storage space in Turgi, 
Switzerland, approximately 12,000 square feet of office and work space in 
Bremen, Germany and approximately 430 square feet of office space in Berlin, 
Germany. Acquisition of real property located in Switzerland by the Company 
or any of its subsidiaries is severely restricted under Swiss law. However, 
IAT does not intend to acquire real property in Switzerland and believes that 
none of its facilities are material to its operations and believes that it 
could find alternate space with minimal interruption to its operations. 

LITIGATION 

   The Company's subsidiaries are parties to certain legal proceedings. The 
Company believes that none of these proceedings is likely to have a material 
adverse effect on the Company's financial position.

Orida provides services for Vertical pursuant to an agreement between Orida and
Vertical. Mr. Agam received a law degree from Tel Aviv University in 1984 and
his LLM in Securities and Corporate Finance from the University of Pennsylvania
in 1986.

   Klaus Grissemann has served as Chief Financial Officer of Multimedia since 
the organization of Multimedia in October 1996 and was elected to serve as a 
director in December 1996. Mr. Grissemann joined IAT AG in 1989 as Chief

   Volker Walther was elected to serve as a director of Multimedia in 
December 1996. In 1996, Mr. Walther became Chief Executive Officer and 
majority shareholder of Walther Glas GmbH, a glass manufacturing company in 
Germany which produces car lights, household glassware and gift items where

until 1991, Mr. Muller was employed by Siemens Germany where he was head of 
research and development for mainframe computer systems from 1987 until 1991. 

   The Board of Directors of Multimedia has determined that, subsequent to 
this Offering, it will elect two directors who are not affiliated with or 
employed by the Company and who in the opinion of the Board of Directors do 
not have a relationship which would interfere with the exercise of 
independent judgement in carrying out the responsibilities of a director (the 
"Independent Directors"). 

                                      49 
<PAGE>


   Directors serve until the next annual meeting or until their successors 
are elected and qualified subject to the provisions of the Investor Rights 
Agreement (as defined herein) which provides that so long as Vertical holds 
at least 10% of the Common Stock to be issued upon conversion of the Series A 
Preferred Stock, Vertical has the right, but not the obligation, to nominate 
two persons as members of the management state for election to Multimedia's 
Board of Directors. So long as Vertical holds at least 5% of such securities, 
it has the right, but not the obligation to nominate one such person. Mr. 
Agam, the Co-Chairman of the Board is the person designated by Vertical and 
elected to the Board of Directors. Vertical plans to nominate a second 
director and the Board of Directors has determined that it will elect such 
person to the Board of Directors. The existence of such rights solidified the 
control over the Company by its existing stockholders. See "Certain 
Transactions -- Private Placement and Related Transactions." Officers serve 
at the discretion of the Board of Directors, subject to rights, if any, under 
contracts of employment with the Company. 

   Board Committees 

   The Board of Directors has appointed Mr. Agam, Dr. Vogt and Mr. Grissemann 
to the Underwriting Committee. Pursuant to the provisions of the Stock 
Purchase Agreement, the Underwriting Committee shall consist of four members 
with two members appointed by each of Vertical and Multimedia. Pending the 
nomination of a second director by Vertical, Vertical has waived its right to 
name a second member to the Underwriting Committee. Mr. Agam, as designated 
by Vertical, serves as the Chairman of the Underwriting Committee. The 
Underwriting Committee is vested with full and exclusive responsibility and 
authority on behalf of Multimedia to select an underwriter and to negotiate 
all of the terms and conditions of any such underwriting including, without 
limitation, this Offering. In the event that the Underwriting Committee is 
unable to produce a majority vote on any particular issue, such issue shall 
be decided by a vote of the Board of Directors of Multimedia provided that 
the resolution of any such issue by the Board of Directors shall not be 
effectuated without the written consent of Vertical. 

   Multimedia intends to establish an Audit Committee, a Compensation 
Committee and a Stock Option Committee. Upon the election of the Independent 
Directors it is expected that the Independent Directors will be members of 
the Compensation Committee with Mr. Agam and the sole members of the Audit 
Committee and the Stock Option Committee. 

   Executive Compensation 

   The following summary compensation table sets forth the aggregate 
compensation paid or accrued by the Company to Dr. Vogt, the Co-Chairman and 
Chief Executive Officer of Multimedia and the three most highly compensated 
executive officers other than Dr. Vogt whose annual salary and bonus exceeds 
$100,000 (the "Named Executive Officers"), during the fiscal year ended 
December 31, 1996:

such payments (including accrued payments) in the future. 


   Employment and Consulting Agreements 

   The Company and Dr. Vogt intend to enter into an employment agreement 
pursuant to which Dr. Vogt agrees to serve as the Company's Co-Chairman,

   Mr. Grissemann is not an employee of the Company. His services are provided
on a per diem basis by Grissemann Consulting S.A. pursuant to an agreement (the
"Grissemann Agreement") dated September 1, 1992 and amended on December 19, 1994
between IAT AG and Grissemann Consulting S.A. The Grissemann Agreement has an
indefinite term and provides that Mr. Grissemann is responsible for the
administration and accounting of IAT AG and that the amount of his business time
which he is to devote to IAT AG's affairs is to be agreed among the parties but
will in no event be less than thirty percent of Mr. Grissemann's business time.
Grissemann Consulting S.A. is paid a per diem fee of SF 775 (approximately $596)
to be amended yearly in line with increases in salary of IAT AG's other
executive officers. In addition, the Grissemann Agreement provides that Mr.
Grissemann will be provided with an automobile at IAT AG's expense.

   IAT AG and Franz Muller entered into an employment agreement on March 1, 1991
(the "Muller Agreement") pursuant to which Mr. Muller was appointed Director of
Product Development (Hardware), Technical Support of IAT AG. The Muller
Agreement has an indefinite term and provides for an annual salary of SF 110,110
(approximately $84,700) and may be terminated by either party upon three months
notice. In addition, the Muller Agreement contains a confidentiality provision
which extends beyond termination of the employment relationship. The Muller
Agreement was amended effective as of July 1, 1993 to provide that Mr. Muller
assigns to IAT AG any and all rights to work and computer programs which he
develops singly or in cooperation with others during the performance of his
duties.

   IAT Germany and Wilhelm Gudauski entered into an employment agreement
effective on January 3, 1994 (the "Gudauski Agreement") pursuant to which Mr.
Gudauski was appointed Manager of Marketing and Sales. On July 12, 1994, Mr.
Gudauski became Managing Director of IAT Germany. The Gudauski Agreement has an
indefinite term and under German law, ends at the mandatory retirement age of
65. The Gudauski Agreement provides for an annual salary of DM 150,000
(approximately $96,774), certain benefits and the payment of an undetermined
bonus upon reaching certain goals to be agreed upon by the parties. The Gudauski
Agreement may be terminated by either party upon six months notice and provides
that Mr. Gudauski may not compete in Germany with IAT Germany for one year upon
termination during which period IAT Germany will be obligated to pay Mr.
Gudauski 70% of his salary, bonus and certain other benefits unless Mr. Gudauski
was terminated for cause.


1996 STOCK OPTION PLAN 

   The Company's Board of Directors has approved and stockholders have 
approved the Company's 1996 Stock Option Plan (the "1996 Plan"). The 1996 
Plan, which provides for a grant of a limited number of non- qualified and 
incentive stock options in respect of up to 500,000 shares of Common Stock to 
eligible employees and advisors, is designed to attract and retain the best 
available personnel for positions of substantial responsibility, to provide 
additional incentive to key employees, officers and advisors to the Company 
and its subsidiaries and to promote the success of the Company's business. 

   Each option granted pursuant to the 1996 Plan is designated at the time of 
grant as either an "incentive stock option" or as a "non-qualified stock 
option." Grants to executive officers may be made only at the fair market 
value of the underlying stock on the date of issuance. The issuance of 
options at fair market value on grant date constitutes a performance goal 
under Section 162(m) of the Internal Revenue Code. The following summary 
description of the Plan is qualified in its entirety by reference to the Plan 
itself, which is filed as an exhibit to the registration statement of which 
this Prospectus is a part. 

   Administration of the Plan. The 1996 Plan will be administered by the 
Stock Option Committee (the "Committee"), which will be appointed by the 
Board of Directors. Only the Independent Directors may serve on the 
Committee. The Committee determines who among those eligible will be granted 
options, the time or times at which options will be granted, the number of 
shares to be subject to each option, the duration of options, any conditions 
to the exercise of options and the date or dates on, and the price at which, 
options may be exercised. 

   The 1996 Plan may be amended by the Board without stockholder approval, 
except that stockholder approval is required to (i) decrease the minimum 
exercise price for incentive stock options ("ISOs"); (ii) extend the term of 
the 1996 Plan beyond ten years; (iii) extend the maximum term of the options 
granted under the 1996 Plan beyond ten years; (iv) withdraw the 
administration of the 1996 Plan from the Committee; (v) expand 

                                      52
<PAGE>

the class of eligible participants; (vi) increase the aggregate number of 
shares of Common Stock which may be issued pursuant to the provisions of the 
1996 Plan; and (vii) change the material terms of the performance goal within 
the meaning of Internal Revenue Code Section 162(m). 

   Unless the Plan is terminated earlier by the Board of Directors, it will 
terminate on the earlier of (i) the date when all shares of the Common Stock 
reserved for issuance under the Plan have been acquired through the exercise 
of options granted thereunder, (ii) January 2007 or (iii) such earlier date 
as the Board of Directors may determine. 

   Shares Subject to the Plan. The 1996 Plan provides that options may be 
granted with respect to a total of 500,000 shares of Common Stock. Under 
certain circumstances involving a change in the number of shares of Common 
Stock without receipt by the Company of any consideration therefor, such as a 
stock split, stock consolidation or payment of a stock dividend, the class 
and aggregate number of shares subject to options under the 1996 Plan will be 
proportionally adjusted. In addition, if the Company is involved in a merger, 
consolidation, dissolution or liquidation, the options granted under the 1996 
Plan will be adjusted. If any option expires or terminates for any reason, 
without having been exercised in full, the unpurchased shares subject to such 
option will be available again for the purposes of the 1996 Plan. 

   Participation. Grants under the 1996 Plan may be granted to employees of 
the Company and its subsidiaries and any other individual who, in the 
judgment of the Committee, provides valuable and important services to the 
Company. Non-employee directors are not eligible to participate in the 1996 
Plan. No participant may receive, in the aggregate, options in respect of 
more than 100,000 shares. 

   Option Price. The exercise price of each option will be determined by the 
Committee. With respect to incentive stock options, the exercise price may 
not be less than 100% of the fair market value of the shares of Common Stock 
covered by the option on the date the option is granted. If an incentive 
stock option is granted to an employee who owns over 10% of the total 
combined voting power of all classes of the Company's stock, then the 
exercise price may not be less than 110% of the fair market value of the 
Common Stock underlying the option on the date the option is granted. The 
exercise price of non-qualified stock options may be any price set by the 
Committee; provided, however, that the exercise price of any grant to any 
executive officer shall not be lower than the fair market value of the 
underlying Common Stock on the date of grant. The issuance of options at fair 
market value on the date of grant constitutes a performance goal under 
Section 162(m) of the Internal Revenue Code. Accordingly, grants under the 
Plan should qualify as performance-based compensation. 

   Term of Options. The Committee shall fix the term of each option, provided 
that the maximum term of each option shall be ten years. Incentive stock 
options granted to a person who owns over 10% of the total combined voting 
power of all classes of the Company's stock shall expire not more than five 
years after the date of grant. The 1996 Plan provides for the earlier 
expiration of options held by a participant under certain terminations of 
employment with the Company. The Committee will have discretion on a case by 
case basis, with respect to any optionee whose employment is terminated for 
any reason whatsoever, to accelerate the vesting of any options outstanding 
on the date employment is terminated to permit the optionee to exercise the 
option during the remaining term of such options. Shares purchased pursuant 
to the exercise of options granted under the 1996 Plan must be paid for in 
United States currency, or, at the Committee's discretion, in shares of the 
Company's Common Stock already owned by the participant exercising the 
options. 

   Restrictions on Transfer, Grant and Exercise. An option may not be 
transferred other than to members of the holder's family, trusts and 
charities. Any other transfers are permissible only upon prior written 
approval of the Committee. Notwithstanding the above, the option agreement 
accompanying the issuance of any incentive stock options shall limit the 
transferability of such ISOs (as defined herein) to the extent required by 
the then- applicable tax provisions governing the qualification of ISOs. The 
aggregate fair market value (determined at the time the option is granted) of 
the shares as to which a Grantee may first exercise incentive stock options 
in any one calendar year may not exceed $100,000. The Committee may impose 
any other conditions on the exercise of options it deems appropriate. 

   Federal Income Tax Consequences to the Company and the Participant. 

   Incentive Stock Options. ISOs: Options granted under the 1996 Plan which 
constitute ISOs will, in general, be subject to the following Federal income 
tax treatment: 

                                      53 
<PAGE>

   (i) The grant of an ISO will give rise to no Federal income tax 
consequences to either the Company or the participant. 

   (ii) A participant's exercise of an ISO will result in no Federal income 
tax consequences to the Company. 

   (iii) A participant's exercise of an ISO will not result in ordinary 
Federal taxable income to the participant, but may result in the imposition 
of an increase of, or an increase in, the alternative minimum tax. A 
participant's holding period for shares acquired upon the exercise of an ISO 
will commence the day after acquisition. If shares acquired upon exercise of 
an ISO are not disposed of within the same taxable year the ISO is exercised, 
the excess of the fair market value of the shares at the time the ISO is 
exercised over the option price is included in the participant's computation 
of alternative minimum taxable income. 

   (iv) If shares acquired upon the exercise of an ISO are disposed of within 
two years of the date of the option grant, or within one year of the date of 
the option exercise, the participant will realize ordinary Federal taxable 
income at the time of the disposition to the extent that the fair market 
value of the shares at the time of exercise exceeds the option price, but not 
in an amount greater than the excess, if any, of the amount realized on the 
disposition over the option price. 

   (v) Short-term or long-term capital gain will be realized by the 
participant at the time of such a disposition to the extent that the amount 
of proceeds from the sale exceeds the fair market value at the time of the 
exercise of the ISO. 

   (vi) Short-term or long-term capital loss will be realized by the 
participant at the time of such a disposition to the extent that the option 
price exceeds the amount of proceeds from the sale. 

   (vii) If a disposition is made as described in this section, the Company 
will be entitled to a Federal income tax deduction in the taxable year in 
which the disposition is made in an amount equal to the amount of ordinary 
Federal taxable income realized by the participant. 

   (viii) If shares acquired upon the exercise of an ISO are disposed of 
after the later of two years from the date of the option grant or one year 
from the date of the option exercise, the participant will realize long-term 
capital gain or loss in an amount equal to the difference between the amount 
realized by the participant on the disposition and the participant's Federal 
income tax basis in the shares, usually the option exercise price. In such 
event, the Company will not be entitled to any Federal income tax deduction 
with respect to the ISO. 

   Non-Qualified Stock Options. Non-Qualified Stock Options ("NQSOs"): 
Options granted under the 1996 Plan which constitute NQSOs will, in general, 
be subject to the following Federal income tax treatment: 

   (i) The grant of an NQSO will give rise to no Federal income tax 
consequences to either the Company or the participant. 

   (ii) The exercise of an NQSO will generally result in ordinary Federal 
taxable income to the participant in an amount equal to the excess of the 
fair market value of the shares at the time of exercise over the option 
price. 

   (iii) A deduction from Federal taxable income will be allowed to the 
Company in an amount equal to the amount of ordinary income recognized by the 
participant. 

   (iv) Upon a subsequent disposition of shares, a participant will recognize 
a short-term or long-term capital gain or loss equal to the difference 
between the amount received and the tax basis of the shares, usually fair 
market value at the time of exercise.

                             CERTAIN TRANSACTIONS 

TRANSACTIONS UNDERTAKEN PRIOR TO ORGANIZATION AND FORMATION OF THE COMPANY 

   Multimedia was formed in September 1996 as a holding company for the 
existing business of IAT AG and IAT Germany which were organized in 1989 and 
1991, respectively. IAT AG and IAT Germany incurred operating losses since 
their inception. As a result, between May 1992 and April 1993, in compliance 
with Swiss law, IAT AG underwent a financial reorganization. IAT AG filed and 
was granted an application for a stay of payment with the applicable court in 
Switzerland and eventually reached a court-approved agreement with its 
unprivileged creditors to accept forgiveness of 90% of their claims and to be 
paid the remaining 10%. In addition, IAT AG also altered its capital 
structure in June 1993. 

   Since 1993 and in compliance with Swiss law, IAT AG took steps to 
safeguard the interests of it's creditors and to raise capital to fund its 
operations by obtaining unsecured subordinated loans not bearing interest and 
having no specific maturity date from former stockholders of IAT AG and 
current stockholders of Multimedia and by obtaining additional shareholders 
equity by increasing the share capital of IAT AG, which according to Swiss 
law is required to be fixed. The share capital was increased in various steps 
from SF 3,000,000 to SF 10,000,000 between 1993 and 1996 except for one 
instance where Robert Klein Handel & Co. GmbH was issued 1,500 shares of IAT 
AG for total cash consideration of SF 1.875 million, ($1.56 million), the 
7,000 additional shares were either paid for in cash on the basis of one 
share for a cash payment of SF 1,000 or by converting loans into share 
capital on the basis of one share for each SF 1,000 in loan forgiveness. In 
October 1996, in connection with the formation of Multimedia, all of the 
10,000 shares of IAT AG for which the shareholders of IAT AG had contributed 
SF 10.275 million ($8.38 million) were exchanged (the "Exchange") for 
4,375,000 shares of Common Stock of Multimedia and the Shareholder Warrant at 
a purchase price equivalent to approximately $1.86 per share of Common Stock 
of Multimedia. 

   In connection with the increase in share capital in July 1996, whereby IAT 
AG issued 900 shares to Volker Walther, a director and stockholder of 
Multimedia for total consideration of SF 900,000, bmp Management Consultants, 
also a stockholder of Multimedia, was paid a finders fee by the Company of 
approximately $60,000. 

   During the period from August to October 1996, Mr. Walther made several 
unsecured subordinated loans to IAT AG in the aggregate amounts of SF 900,000 
($720,000) and DM 700,000 ($462,000). These loans have an annual interest 
rate of 10% and provide that they will be repaid at the earlier of the 
consummation of this Offering or June 30, 1997. 

   On November 6, 1996, Klaus-Dirk Sippel, a principal stockholder of 
Multimedia, made an unsecured subordinated loan to IAT AG in the amount of SF 
650,000 ($520,000). A portion of this loan was used to repay an unsecured 
non-interest bearing loan in the amount of SF 150,000 ($120,000) made in 
February 1996 to IAT AG by Telefutura, a company controlled by Klaus-Dirk 
Sippel. This loan has an annual interest rate of 8% and principal and accrued 
interest are due and payable on January 1, 1998. In December 1996, Vertical 
transferred 200,000 Investor Warrants it had purchased in the Private 
Placement to Mr. Sippel. 

   In connection with the operations of IAT Germany, the capital was 
increased in 1993 and 1995 from the initial DM 100,000 ($  ) to the current 
DM 700,000 ($  ). In addition, on December 19, 1995, HIBEG, the 25.1% 
shareholder of IAT Germany, made an unsecured subordinated loan to IAT 
Germany in the amount of approximately DM 750,000 (the "HIBEG Loan"). The 
HIBEG Loan bears interest at 5% per annum payable semi-annually and will be 
increased to 10% per annum during the year when the retained earnings of IAT 
Germany exceeds DM 87,500 (approximately $58,000). IAT Germany will be 
required to make semi-annual payments of 10% of the principal starting on 
June 30, 2000 until the principal is repaid in full. 

   In addition to the transactions listed above, Messrs. Sippel and Suter 
have jointly and severally guaranteed two loans in the aggregate amount of SF 
600,000 ($480,000) of two loans and each of Messrs. Sippel, Suter and 
Holthuisen have jointly and severally guaranteed IAT AG's credit line in the 
amount of SF 700,000 ($560,000) under IAT AG's credit agreement with Swiss 
Bank Corporation for SF 1,900,000 ($1.52 million). Furthermore, IAT AG has 
guaranteed one of two credit lines of IAT Germany from Volksbank Sottrum in 
the amount of DM 700,000 (approximately $555,600) and HIBEG. Dr. Vogt and Mr. 
Gudauski have each guaranteed the second credit line of IAT Germany from 
Volksbank Sottrum in the amount of DM 350,000 (approximately $228,800). These 
guarantees are offset by a lien on accounts receivable balances.

PRIVATE PLACEMENT AND RELATED TRANSACTIONS 

   Simultaneously with the Exchange, pursuant to the Stock Purchase Agreement 
between the Company, IAT AG, IAT Germany and Vertical dated October 24, 1996 
(the "Stock Purchase Agreement"), the Company completed the Private Placement 
and issued an aggregate of 1,980,000 shares of Series A Preferred Stock and 
the Investor Warrants to Vertical, Behala Anstalt, Lupin Investments Services 
Ltd., Henilia Financial Ltd. and Avi Suriel for an aggregate purchase price 
of $1.5 million or $.76 per share of Series A Preferred Stock of Multimedia. 
See "Principal Stockholders." 

   The Stock Purchase Agreement contains certain continuing obligations of 
the Company. Pursuant to the Stock Purchase Agreement, Multimedia is 
obligated to use all reasonable efforts to file a registration statement 
containing this Prospectus no later than December 31, 1996. In addition, 
Multimedia is obligated to establish an underwriting committee of its Board 
of Directors consisting of four members with two members appointed by each of 
Vertical and Multimedia. Vertical has the right to designate the Chairman of 
the underwriting committee which is vested with full and exclusive 
responsibility and authority on behalf of Multimedia to select an underwriter 
and to negotiate all of the terms and conditions of any such underwriting 
including, without limitation, this Offering. In the event that the 
underwriting committee is unable to produce a majority vote on any particular 
issue, such issue shall be decided by a vote of the Board of Directors of 
Multimedia, provided, that the resolution of any such issue by the Board of 
Directors shall not be effectuated without the written consent of Vertical. 

   The Stock Purchase Agreement further provides that, if on the effective 
date of this Offering, the aggregate value of the shares of Common Stock (as 
measured by the per share offering price of the shares of Common Stock 
offered in this Offering) owned by non-management stockholders of Multimedia 
(the "Non-Management Stockholders") is less than $15,000,000 (the amount of 
such shortfall being hereinafter referred to as the "Shortfall"), Vertical 
and Dr. Viktor Vogt, Klaus Grissemann, Wilhelm Gudauski, Franz Muller and 
other members of management (the "Management Stockholders") shall, within 
five business days of the consummation of this Offering, transfer to the 
Non-Management Stockholders such additional number of shares of Common Stock 
as shall have a value equal to the Shortfall, with Vertical contributing 60% 
of the Shortfall and the Management Stockholders contributing 40% of the 
shortfall, pro rata. Alternatively, if on the effective date of this 
Offering, the aggregate value of the shares of Common Stock (as measured by 
the per share offering price of the shares of Common Stock offered in this 
Offering) owned by the Non-Management Stockholders is greater than 
$25,000,000 (the amount of such excess amount being hereinafter referred to 
as the "Excess Amount"), the Non-Management Stockholders shall, within five 
business days of the consummation of this Offering, distribute, without any 
further consideration, such number of shares of Common Stock as shall have a 
value equal to (i) 60% of the Excess Amount to Vertical and (ii) 40% of the 
Excess Amount to the Management Stockholders, pro rata according to their 
respective stockholdings. 

   The Stock Purchase Agreement further provides that until October 24, 1999 
Multimedia shall pay to Vertical monthly compensation to Vertical for the 
services of the Co-Chairman of the Company nominated by Vertical each month 
prior to the consummation of this Offering of $5,000 and for each month 
subsequent to the consummation of this Offering of $12,000. Jacob Agam is the 
current nominee of Vertical. To date, the Company has not made these payments 
but has accrued such payments and intends to make such payments (including 
accrued payments) in the future. 

   Multimedia further agreed that, for so long as Vertical shall hold the 
Series A Preferred Stock (or Common Stock issued upon conversion thereof or 
upon exercise of the Investor Warrant), without Vertical's consent, the 
composition of the Board of Directors of IAT AG and IAT Germany shall be 
identical to the composition of the Board of Directors of Multimedia; 
provided, that consent shall not be withheld if required to comply with Swiss 
law. 

   Multimedia has further agreed that it will cause IAT AG and IAT Germany 
not to issue, and will not permit the issuance of, any shares of capital 
stock (or any security convertible into shares of capital stock) of IAT AG or 
IAT Germany, it being the intention of Multimedia and Vertical that IAT AG 
shall remain a direct or indirect wholly-owned subsidiary of Multimedia and 
IAT Germany shall remain a direct or indirect subsidiary of Multimedia. 

                                      56 
<PAGE>


   Amendment No. 1 to the Stock Purchase Agreement to be entered into by the 
parties will provide that Vertical shall not enter into an agreement or make 
any investment in an entity engaged in the visual communications business 
prior to January 1, 1998 and that subsequent to January 1, 1998, Vertical, 
prior to entering into an agreement or making any investment in an entity 
engaged in the visual communications business will provide the Company the 
opportunity to enter into such agreement or make such investment instead of 
Vertical. 

   In connection with the Private Placement, the Company also entered into 
the Investor Rights Agreement with Vertical (the "Investor Rights Agreement") 
which provides that Vertical has the right, but not the obligation, to 
nominate as a member of the management slate for election to the Company's 
Board of Directors one or two persons for so long as Vertical will hold at 
least 5% or 10%, respectively, of the Series A Preferred Stock (or at least 
5% or 10%, respectively, of the Common Stock issuable upon conversion of the 
Series A Preferred Stock or upon exercise of the Investor Warrants). The 
Company agreed that one such person shall be elected Co-Chairman of the Board 
of Directors of the Company. The Investor's Rights Agreement further provides 
for one demand and two piggy-back registration rights with respect to the 
Common Stock issuable upon conversion of the Series A Preferred Stock and the 
exercise of the Investor Warrants. 

   In addition, also in connection with the Private Placement, the Company 
entered into the Marketing Agreement with General Capital, an affiliate of 
Vertical. The Marketing Agreement provides that General Capital will assist 
the Company in connection with marketing its products worldwide, arranging 
debt or equity financing for the Company's products to be purchased by its 
customers, and arranging financing for the Company's operations, leasing 
programs, joint ventures and distribution arrangements, in each case for the 
further enhancement of the Company's marketing strategy. The Marketing 
Agreement has a five year term and expires on October 26, 2001. Pursuant to 
the Marketing Agreement, the Company paid $100,000 at the closing of the 
Private Placement and is obligated to pay $300,000 at such time as the 
Company's consolidated stockholders' equity exceeds $6,000,000 and an 
additional $100,000 payable at such time as the Company's consolidated 
stockholders' equity exceeds $8,000,000, provided that the current 
liabilities of the Company used to determine the consolidated stockholders' 
equity of the Company shall not exceed $3,500,000 and, to the extent it 
exceeds $3,500,000 any such additional amounts shall not reduce such 
stockholders' equity. The consummation of this Offering will trigger the 
$400,000 payment which will be made with the proceeds of this Offering. The 
Marketing Agreement further provides that Multimedia will provide General 
Capital with certain technical and other information relating to its business 
and operations as is reasonable and necessary for General Capital to market 
the Company's products. In addition, Multimedia will provide General Capital 
with the necessary sales promotion materials to market the Company's products 
and Multimedia shall make its management available to General Capital and 
prospective customers at such reasonable times and locations as is necessary 
for General Capital to market Multimedia's products. In connection with these 
provisions, General Capital agrees that, during the term of the Marketing 
Agreement and for a period of five years following such term, it shall not 
disclose to any third party any trade secrets or other confidential 
information for any purpose other than the performance of its duties under 
the Marketing Agreement and upon the prior written approval of Multimedia. 
General Capital further agreed that during the term of the Marketing 
Agreement and for a period of two years thereafter it shall not directly or 
indirectly own, manage, control, participate in, consult with, render 
services for, or in any manner engage in any business competing with the 
business of Multimedia as such business exists within any geographical area 
in which Multimedia conducts its business. Either party may terminate the 
Marketing Agreement at any time after June 30, 1997 if the Company's working 
capital does not exceed $4,000,000 by such date, provided, however, that in 
the event that the Company's working capital exceeds such amount by June 30, 
1997, the Marketing Agreement will not be terminable by either party. 

   Amendment No. 1 to the Marketing Agreement to be entered into by the 
parties will provide that General Capital, during the term of the Marketing 
Agreement and for a period of three years thereafter shall not directly or 
indirectly own, manage, control, participate in, consult with, render 
services for, or in any manner engage in any business competing with the 
business of Multimedia without any geographical limitation. 

REVERSE STOCK SPLIT 

   In connection with the Reverse Stock Split effected by the Company in 
December 1996, the outstanding capital stock of the Company was reduced from 
an aggregate of 6,600,000 shares to 6,250,000 resulting in 4,375,000 shares 
of Common Stock and 1,875,000 shares of Series A Preferred Stock outstanding.

ESCROW SHARES 

   The existing stockholders of the Company will deposit an aggregate of 
500,000 shares of Common Stock into escrow. The Escrow Shares are not 
assignable or transferable. Of the Escrow Shares, 

   (i) 166,666 shall be released from escrow if, for the fiscal year ending 
December 31, 1997, the Company's minimum revenues (the "Minimum Revenues") 
equals or exceeds $5.5 million; 

   (ii) 166,666 Escrow Shares (or, if the conditions set forth in (i) above 
was not met, 333,332 Escrow Shares) shall be released, if, for the fiscal 
year ending December 31, 1998, the Minimum Revenues equals or exceeds $8.0 
million; 

   (iii) 166,668 Escrow Shares (or, if the conditions set forth in either (i) 
or (ii) were not met, the remaining Escrow Shares) shall be released if, for 
the fiscal year ending December 31, 1999, the Minimum Revenues equals or 
exceeds $12.0 million and the Company's income before provision for taxes 
(the "Minimum Pretax Income") equals or exceeds $1.0 million; and 

                                      60 
<PAGE>

   (iv) all of the Escrow Shares will be released from escrow if one or more 
of the following conditions is/are met: 

   (a) the average of the closing bid prices of the Company's Common Stock 
for any 30 consecutive trading days commencing 24 months after the Effective 
Date exceeds $13.00 per share; or 

   (b) the Company is acquired by or merged into another entity during the 
period set forth in (a) above in a transaction in which the value of the per 
share consideration received by the stockholders of the Company (after giving 
effect to the release from escrow) on the date of such transaction exceeds 
$13.00 per share. 

   The Minimum Revenues and Minimum Pretax Income Amounts set forth above 
shall be (i) derived solely from the business currently owned and operated by 
the Company and shall not give effect to any operations relating to business 
or assets acquired in the future; (ii) calculated exclusive of any 
extraordinary earnings including, but not limited to, any charge to income 
resulting from the release of the Escrow Shares and (iii) audited by the 
Company's independent public accountants. 

   Any money, securities, rights or property distributed in respect of the 
Escrow Shares shall be received by the escrow agent, including any property 
distributed as dividends or pursuant to any stock split, merger, 
recapitalization, dissolution or total or partial liquidation of the Company 
(the "Escrow Property"). On March 31, 2000, any remaining Escrow Shares, as 
well as any dividends or other distributions made with respect thereto, will 
be canceled and contributed to the capital of the Company. The Company 
expects that the release of the Escrow Shares to officers, directors, 
employees and consultants of the Company will be deemed compensatory and, 
accordingly, will result in a substantial charge to operations, which would 
equal the then fair market value of such shares. Such charges could 
substantially increase the loss or reduce or eliminate the Company's net 
income for financial reporting purposes for the period during which such 
shares are, or become probable of being, released from escrow. Although the 
amount of compensation expense recognized by the Company will not affect the 
Company's total stockholder's equity, it may have a negative effect on the 
market price of the Company's securities. See "Management's Discussion and 
Analysis of Financial Condition and Results of Operations" and Note 4 of the 
Notes to the Company's Financial Statements. 

   The Minimum Revenues and Minimum Pretax Income amounts and closing bid 
price levels set forth above were determined by negotiation between the 
Company and the Underwriters and should not be construed to imply or predict 
any future earnings by the Company or any increase in the market price of its 
securities.

                          DESCRIPTION OF SECURITIES 

   The authorized capital stock of Multimedia consists of 20,000,000 shares 
of Common Stock, par value $.01 per share, 2,375,000 shares of preferred 
stock, par value $.01 per share (the "Preferred Stock"), including 500,000 
shares of Blank Check Preferred Stock. Prior to this Offering, Multimedia had 
issued and outstanding 4,375,000 shares of its Common Stock and 1,875,000 
shares of Series A Preferred Stock. Upon consummation of this Offering, 
Multimedia will have issued and outstanding an aggregate of 9,350,000 shares 
of its Common Stock including 1,875,000 shares of Common Stock issued upon 
automatic conversion of all of the outstanding Series A Preferred Stock. Upon 
conversion of the Series A Preferred Stock, all of the Series A Preferred 
Stock will be cancelled. 


UNITS 

   Each Unit consists of one share of Common Stock and one Warrant. Each 
Warrant entitles the holder thereof to purchase one share of Common Stock. 
The Common Stock and Warrants comprising the Units are transferable 
separately immediately upon issuance. 

COMMON STOCK 

   Holders of Common Stock have the right to cast one vote for each share 
held of record on all matters submitted to a vote of the stockholders, 
including the election of directors. Holders of Common Stock are entitled to 
receive such dividends, pro rata, based on the number of shares held, when, 
as and if declared by the Board of Directors, from funds legally available 
therefor, subject to the rights of holders of any outstanding preferred 
stock. Multimedia has never paid cash dividends on its Common Stock and does 
not anticipate or intend paying cash dividends in the foreseeable future on 
its Common Stock. In the event of the liquidation, dissolution or winding up 
of the affairs of Multimedia, all assets and funds of Multimedia remaining 
after the payment of all debts and other liabilities, subject to the rights 
of the holders of any outstanding Preferred Stock, shall be distributed to 
the holders, pro rata on a per share basis, among the holders of the Common 
Stock. Holders of Common Stock are not entitled to preemptive, subscription, 
cumulative voting or conversion rights, and there are no redemption or 
sinking fund provisions applicable to the Common Stock. All outstanding 
shares of Common Stock are, and the shares of Common Stock included in the 
Units offered hereby will be, when issued, fully paid and non-assessable. 

WARRANTS 

   Each Warrant entitles the registered holder to purchase one share of 
Common Stock at an exercise price of $7.80, subject to adjustment at any time 
from the Separation Date until 5:00 P.M., New York City time, on     , 2002. 
Commencing 15 months from the date of this Prospectus, the Warrants are 
redeemable by the Company on 30 days' written notice at a redemption price of 
$.05 per Warrant provided the closing price of the Common Stock for any 20 
consecutive trading days ending within five days of the notice of redemption 
equals or exceeds $16.00 per share. "Closing price" shall mean the closing 
bid price if listed in the over-the-counter market on Nasdaq or otherwise or 
the closing sale price if listed on the Nasdaq National Market or a national 
securities exchange. All Warrants must be redeemed if any are redeemed. 

   The Warrants will be issued pursuant to a warrant agreement (the "Warrant 
Agreement") among Multimedia, the Underwriter and American Stock Transfer & 
Trust Company, as warrant agent, and will be evidenced by warrant 
certificates in registered form. The Warrants provide for adjustment of the 
exercise price and for a change in the number of shares issuable upon 
exercise to protect holders against dilution in the event of a stock 
dividend, stock split, combination or reclassification of the Common Stock or 
upon issuance of shares of Common Stock at prices lower than the market price 
of the Common Stock, with certain exceptions. 

   The exercise price of the Warrants was determined by negotiation between 
Multimedia and the Underwriter and should not be construed to be predictive 
of or to imply that any price increases in Multimedia's securities will 
occur. 


   A Warrant may be exercised upon surrender of the Warrant certificate on or 
prior to its expiration date (or earlier redemption date) at the offices of 
American Stock Transfer & Trust Company, the warrant agent, with the 


                                      62 
<PAGE>

form of "Election to Purchase" on the reverse side of the Warrant certificate 
completed and executed as indicated, accompanied by payment of the full 
exercise price (by certified or bank check payable to the order of 
Multimedia) for the number of shares with respect to which the Warrant is 
being exercised. Shares issued upon exercise of Warrants and payment in 
accordance with the terms of the Warrants will be fully paid and non- 
assessable. 

   The Warrants do not confer upon the Warrantholder any voting or other 
rights of a stockholder of Multimedia. Upon notice to the Warrantholders, 
Multimedia has the right to reduce the exercise price or extend the 
expiration date of the Warrants. 

UNIT PURCHASE OPTIONS 

   Upon the closing of this Offering, Multimedia has agreed to sell for 
nominal consideration to the Underwriter or its designees the Unit Purchase 
Options to purchase up to 310,000 Units. These Units will be identical to the 
Units offered hereby except that the Warrants included in the Unit Purchase 
Options will not be subject to redemption by Multimedia unless, at the time 
the Warrants are called for redemption, the Unit Purchase Options have been 
exercised and the underlying warrants are outstanding. The Unit Purchase 
Options cannot be transferred, sold, assigned or hypothecated for two years, 
except to any officer of the Underwriter or members of the selling group or 
their officers. The Unit Price Options are exercisable during the four-year 
period commencing one year from the date of this Prospectus at an exercise 
price of $9.90 per Unit (165% of the initial public offering price) subject 
to adjustment in certain events to protect against dilution. The holders of 
the Unit Purchase Options have certain demand and piggy-back registration 
rights. See "Underwriting." 

PREFERRED STOCK 

SERIES A PREFERRED STOCK 

   Dividends. The holders of the Series A Preferred Stock are entitled to 
receive mandatory preferential dividends at the rate of $.056 per share (as 
adjusted for stock splits, combinations or similar events) during the one 
year period from October 4, 1996 to October 24, 1997, which dividends shall 
be accrued and shall be paid, in cash, upon the earlier of (i) the 
consummation of this Offering at which time all shares of Series A Preferred 
Stock will automatically convert at the then-effective Conversion Rate (as 
defined below) or (ii), in the event this Offering is not consummated, on 
October 24, 1997. 

   Liquidation Preference. In the event of any liquidation, dissolution or 
winding up of Multimedia, either voluntary or involuntary, the holders of the 
Series A Preferred Stock are entitled to receive, prior and in preference to 
any distribution of any of the assets of Multimedia to any holders of Common 
Stock, an amount per share equal to $.080 (as adjusted for stock splits, 
combinations or similar events) for each outstanding share of Series A 
Preferred Stock plus any accrued or declared but unpaid dividends (the 
"Liquidation Preference"). If, upon the occurrence of such an event, the 
assets and funds thus distributed among the holders of the Series A Preferred 
Stock shall be insufficient to permit the payment to such holders of the full 
Liquidation Preference, then the entire assets and funds of Multimedia 
legally available for distribution shall be distributed ratably among the 
holders of the Series A Preferred Stock such that an equal amount shall be 
paid with respect to each outstanding share of Series A Preferred Stock. 

   Redemption. Multimedia is obligated to redeem the Series A Preferred Stock 
at the Liquidation Preference upon the written request of the holders of any 
outstanding shares of Series A Preferred Stock at any time following October 
4, 1998. If, at any time after December 31, 1997, Multimedia has not 
consummated this Offering, Multimedia may redeem all, but not less than all, 
of the outstanding shares of Series A Preferred Stock at the Liquidation 
Preference. To the extent that Multimedia does not have funds legally 
available to fund any required redemption of shares of Series A Preferred 
Stock, Multimedia shall use its commercially reasonable best efforts to raise 
sufficient capital to fund such required redemption within 60 days of the 
date such redemption is required to be made. To the extent that Multimedia is 
unable to raise sufficient capital to fund such required redemption within 
such period, Multimedia shall commence, as of the 61st day following the date 
such redemp-

                                      63 
<PAGE>


tion is required to be made, a rights offering of Multimedia's Common Stock 
to all of Multimedia's shareholders of an adequate number of shares at a 
purchase price per share equal to its then fair market value such that the 
total dollar amount to be raised from such rights offering will equal or 
exceed the dollar amount needed by Multimedia to fund such required 
redemption. 

   Conversion. Each share of Series A Preferred Stock is convertible, at the 
option of the holder thereof at any time after the date of issuance of such 
share. Each share of Series A Preferred Stock shall be convertible into the 
number of fully paid and nonassessable shares of Common Stock equal to a 
fraction, the numerator of which is the "Conversion Value" per share of such 
Series A Preferred Stock and the denominator of which is the "Conversion 
Price" per share in effect for such Series A Preferred Stock at the time of 
conversion. The number of shares of Common Stock into which each share of 
Series A Preferred Stock is convertible is hereinafter collectively referred 
to as the "Conversion Rate" for such series. The Conversion Price of each of 
the Series A Preferred Stock is subject to adjustment to protect against 
certain antidilutive events. The initial Conversion Price per share of Series 
A Preferred Stock is $.80, subject to adjustment for stock splits, 
combinations or similar events affecting the Series A Preferred Stock. The 
Conversion Value per share of Series A Preferred Stock is $.80. As of the 
date of this Prospectus, each share of Series A Preferred Stock will convert 
into 1,875,000 shares of Common Stock upon the consummation of this Offering. 

   Voting Rights. Except with respect to the election of members of 
Multimedia's Board of Directors, the Series A Preferred Stock are entitled to 
vote on all matters as to which the holders of Common Stock are entitled to 
vote with each share of Series A Preferred Stock having that number of votes 
equal to the number of shares of Common Stock into which it is then 
convertible. 

   Status of Converted Stock. Upon consummation of this Offering and the 
conversion of the Series A Preferred Stock, the shares so converted shall be 
canceled by Multimedia. See "-- Preferred Stock." 

   Right to Elect Certain Directors. Provided that there are at least five 
directors, for so long as the holders of Series A Preferred Stock hold at 
least 5% of Multimedia's Series A Preferred Stock (or 5% of the Common Stock 
issued upon conversion of the Series A Preferred Stock or upon exercise of 
any warrants held by such holder), the holders of the Series A Preferred 
Stock voting as a separate class, shall have the right to elect one 
individual to Multimedia's Board of Directors and so long as the holders of 
at least 10% of Multimedia's Series A Preferred Stock (or 10% of the Common 
Stock issued upon conversion of the Series A Preferred Stock or upon exercise 
of any warrants held by such holder), such holders voting as a separate 
class, shall have the right to elect two individuals to Multimedia's Board of 
Directors, including one member who shall be elected as Co-Chairman of the 
Board of Directors. The Series A Directors shall be elected at the same time 
as the election of the other members of the Board of Directors. In the event 
of the resignation or removal of a Series A Directors, a special meeting 
shall be convened at which elections shall be held for the election of a 
substitute Series A Director, provided that such holders may act by unanimous 
consent in lieu of such meeting. 

   Covenants. So long as any shares of Series A Preferred Stock are 
outstanding, Multimedia shall not without first obtaining the written consent 
of the holders of at least two-thirds of the then outstanding shares of 
Series A Preferred Stock, among other things, sell all or substantially all 
of the assets of Multimedia, merge in any transaction in which more than 50% 
percent of the voting power of Multimedia is disposed of, engage in any 
spin-out, distribution or sale of any business unit of Multimedia, increase 
or decrease the total number of authorized shares of Series A Preferred Stock 
or amend the terms of the Series A Preferred Stock so as to affect adversely 
the Series A Preferred Stock, authorize or issue any other equity security 
having a preference over, or being on a parity with the Series A Preferred 
Stock with respect to dividends, redemption or liquidation, redeem or 
repurchase any outstanding equity securities of the Company, to issue shares 
of Common Stock to employees, advisors, consultants or outside directors if 
the cumulative total number of shares of Common Stock so issued exceeds 
748,000, increase the authorized number of directors of Multimedia to more 
than five members, liquidate, dissolve or otherwise wind up the affairs of 
Multimedia, enter into any transactions with affiliates of Multimedia except 
on arms-length terms or pay any dividend on or any distribution with respect 
of any shares of capital stock other than the dividends paid on the Series A 
Preferred Stock in accordance with its terms. 


BLANK CHECK PREFERRED STOCK 

   The Company is authorized to issue up to 500,000 shares of Preferred 
Stock. The Board of Directors has the authority to issue this Preferred Stock 
in one or more series and to fix the number of shares and the relative 

                                      64
<PAGE>

rights, conversion rights, voting rights and terms of redemption (including 
sinking fund provisions) and liquidation preferences, without further vote or 
action by the stockholders. If shares of Preferred Stock with voting rights 
are issued, such issuance could affect the voting rights of the holders of 
the Company's Common Stock by increasing the number of outstanding shares 
having voting rights, and by the creation of class or series voting rights. 
If the Board of Directors authorizes the issuance of shares of Preferred 
Stock with conversion rights, the number of shares of Common Stock 
outstanding could potentially be increased by up to the authorized amount. 
Issuances of Preferred Stock could, under certain circumstances, have the 
effect of delaying or preventing a change in control of the Company and may 
adversely affect the rights of holders of Common Stock. Also, Preferred Stock 
could have preferences over the Common Stock (and other series of preferred 
stock) with respect to dividend and liquidation rights. The Company currently 
has no plans to issue any Preferred Stock. 

INVESTOR WARRANTS AND SHAREHOLDER WARRANTS 

   Each of the Investor Warrants and the Shareholders Warrants entitle the 
holder to purchase one share of Common Stock at an exercise price per share 
equal to 130% of the initial public offering price at any time or from time 
to time during the ten year period following the consummation of this 
Offering, but not later than 5:00 P.M., New York City time, on December 31, 
2006. Each of the Investor Warrants and the Shareholders Warrants provide for 
adjustment of the exercise price and for a change in the number of shares 
issuable upon exercise to protect holders against dilution in the event of a 
stock dividend, stock split, combination or reclassification of the Common 
Stock or upon issuances of shares of Common Stock at prices lower than the 
market price of the Common Stock, with certain exceptions. 

   Each of the Investor Warrants and the Shareholder Warrants may be 
exercised upon surrender of the certificate evidencing the Investor Warrant 
or the Shareholder Warrant on or prior to its expiration date at the offices 
of the Company or the Transfer Agent (as defined below), with the form of 
"Election to Purchase" on the reverse side of the Warrant certificate 
completed and executed as indicated, accompanied by payment of the full 
exercise price (by certified or bank check payable to the order of the 
Company) for the number of shares with respect to which the Investor Warrant 
or Shareholder Warrant is being exercised. Shares issued upon exercise of 
Investor Warrants or Shareholder Warrants and payment in accordance with the 
terms of the Investor Warrants or Shareholders Warrants will be fully paid 
and non-assessable. 

   The Investor Warrants or the Shareholder Warrants do not confer upon the 
holders of the Investor Warrants or the Shareholder Warrants any voting or 
other rights of a stockholder of the Company. 

   Upon exercise of the Investor Warrants or the Shareholder Warrants, the 
holders of the Common Stock issued upon such exercise will have registration 
rights as set forth in the Investor's Rights Agreement. See "Certain 
Transactions -- Private Placement and Related Transactions." 

TRANSFER AGENT 

   American Stock Transfer & Trust Company serves as Transfer Agent for the 
shares of Common Stock and Warrant Agent for the Warrants. 

BUSINESS COMBINATION PROVISIONS 

   The Company is subject to the "business combination" statute of the 
Delaware Law, an anti-takeover law enacted in 1988. In general, Section 203 
of the Delaware Law prohibits a publicly-held Delaware corporation from 
engaging in a "business combination" with an "interested stockholder" for a 
period of three years after the date of the transaction in which the person 
became an "interested stockholder," unless (a) prior to such date the board 
of directors of the corporation approved either the "business combination" or 
the transaction which resulted in the stockholder becoming an "interested 
stockholder," (b) upon consummation of the transaction which resulted in the 
stockholder becoming an "interested stockholder," the "interested 
stockholder" owned at least 85% of the voting stock of the corporation 
outstanding at the time the transaction commenced, excluding for purposes of 
determining the number of shares outstanding those shares owned (i) by 
persons who are directors and also officers and (ii) employee stock plans in 
which employee participants do not have the right to determine confidentially 
whether shares held subject to the plan will be tendered in a tender or 
exchange offer, 

                                      65
<PAGE>

or (c) on or subsequent to such date the "business combination" is approved 
by the board of directors and authorized at an annual or special meeting of 
stockholders by the affirmative vote of at least 66 2/3 % of the outstanding 
voting stock which is not owned by the "interested stockholder." A "business 
combination" includes mergers, stock or asset sales and other transactions 
resulting in a financial benefit to the "interested stockholders." An 
"interested stockholder" is a person who, together with affiliates and 
associates, owns (or within three years, did own) 15% or more of the 
corporation's voting stock. Although Section 203 permits the Company to elect 
not to be governed by its provisions, the Company to date has not made this 
election. Upon closing of this Offering and the registration of its shares of 
Common Stock under the Exchange Act, the restrictions imposed by such statute 
will apply to the Company and, as a result of the application of Section 203, 
potential acquirers of the Company may be discouraged from attempting to 
effect an acquisition transaction with the Company, thereby possibly 
depriving holders of the Company s securities of certain opportunities to 
sell or otherwise dispose of such securities at above-market prices pursuant 
to such transactions.

                       SHARES ELIGIBLE FOR FUTURE SALE 

   Upon completion of this Offering the Company will have 9,350,000 shares of 
Common Stock outstanding. Of these shares outstanding, the 3,100,000 shares 
of Common Stock included in the Units offered hereby will be freely 
transferable without restriction or further registration under the Securities 
Act, unless purchased by affiliates of the Company as that term is defined in 
Rule 144 under the Securities Act ("Rule 144") described below. All of the 
6,250,000 shares of Common Stock held by existing stockholders are eligible 
for sale under Rule 144 beginning in October 1998. Of the outstanding shares 
of Common Stock, 500,000 shares are Escrow Shares. Currently 5,827,000 of the 
6,250,000 shares of Common Stock outstanding are held by affiliates and will 
be subject to volume limitations after October 1998. In addition, holders of 
the outstanding shares of Common Stock have agreed not to sell or otherwise 
dispose of any shares of Common Stock, without the Underwriter's prior 
written consent for a period of two years after the consummation of this 
Offering. See "Underwriting." 

   In addition, the Investor Warrants, the Shareholder Warrants and the 
2,348,485 shares of Common Stock issuable upon exercise of the Investor 
Warrants and the Shareholders Warrants are also "restricted securities" and 
may not be sold publicly unless they are registered under the Securities Act 
or are sold pursuant to Rule 144 on another exemption from registration. None 
of such warrants or shares will be eligible for sale in the public market 
pursuant to Rule 144 until October 1998. 

   Upon completion of this Offering, the Company will have outstanding in 
addition to the securities referred to above, (i) the Warrants to purchase an 
aggregate of 3,100,000 shares of Common Stock and (ii) the Unit Purchase 
Options to purchase an aggregate of 620,000 shares of Common Stock, assuming 
exercise of the underlying Warrants. In addition, the Company has reserved 
for issuance 500,000 shares of Common Stock in connection with the 1996 Stock 
Option Plan. 

   In general under Rule 144, a person (or persons whose shares are 
aggregated), including persons who may be deemed to be "affiliates" of the 
Company as that term is defined under the Securities Act, is entitled to sell 
within any three-month period a number of restricted shares beneficially 
owned for at least two years that does not exceed the greater of (i) 1% of 
the then outstanding shares of Common Stock or (ii) the average weekly 
trading volume in the Common Stock during the four calendar weeks preceding 
such sale. Sales under Rule 144 are also subject to certain requirements as 
to the manner of sale, notice and the availability of current public 
information about the Company. However, a person who is not an affiliate and 
has beneficially owned such shares for at least three years is entitled to 
sell such shares without regard to the volume or other resale requirements. 


   Vertical has demand and piggy-back registration rights covering the 
securities held by it. In addition, the Underwriters also have demand and 
piggy-back registration rights with respect to the securities underlying the 
Unit Purchase Options. See "Underwriting." 


   Prior to this Offering, there has been no market for any securities of the 
Company, and no predictions can be made of the effect, if any, that sales of 
Common Stock or the availability of Common Stock for sale will have on the 
market price of such securities prevailing from time to time. Nevertheless, 
sales of substantial amounts of Common Stock in the public market could 
adversely affect prevailing market prices.

                                 UNDERWRITING 

   Royce Investment Group, Inc., the Underwriter, has agreed, subject to the 
terms and conditions of the Underwriting Agreement between the Company and 
the Underwriter (the "Underwriting Agreement"), to purchase from the Company 
the 3,100,000 Units offered hereby on a firm commitment basis, if any are 
purchased. 

   The Underwriter has advised the Company that it proposes to offer the 
Units to the public at the public offering price set forth on the cover page 
of this Prospectus and to certain dealers who are members of the National 
Association of Securities Dealers, Inc. (the "NASD"), at such price less a 
concession of not in excess of $   per Unit, of which a sum not in excess of 
$   may in turn be reallowed to other dealers who are members of the NASD. 
After the commencement of the Offering, the public offering price, the 
concession and the reallowance may be changed by the Underwriter. 

   The Company has agreed to indemnify the Underwriter against certain 
liabilities, including liabilities under the Securities Act. The Company has 
also agreed to pay to the Underwriter a non-accountable expense allowance 
equal to 2.5% of the gross proceeds derived from the sale of the Units 
offered hereby, including any Units purchased pursuant to the Underwriter's 
over-allotment option, $50,000 of which has been paid to date. 

   The Company has granted to the Underwriter an option exercisable during 
the 45-day period commencing on the date of this Prospectus, to purchase from 
the Company at the public offering price set forth on the cover page of this 
Prospectus less underwriting discounts and commissions, up to 465,000 
additional Units for the purpose of covering over-allotments, if any, made in 
connection with the sale of the Units. 

   All of the Company's current stockholders and all officers and directors 
of the Company have agreed not to sell, assign, transfer or otherwise dispose 
publicly of any of their shares of capital stock for a period of 24 months 
from the date of this Prospectus without the prior written consent of the 
Underwriter. 

   The Company has agreed not to solicit Warrant exercises other than through 
the Underwriter. Upon any exercise of the Warrants after the first 
anniversary of the date of this Prospectus, the Company will pay the 
Underwriter a fee of 6% of the aggregate Warrant exercise price, if (i) the 
market price of the Company's Common Stock on the date the Warrants are 
exercised is greater than the then exercise price of the Warrants, (ii) the 
exercise of the Warrants was solicited by a member of the NASD, (iii) the 
Warrants are not held in a discretionary account, (iv) disclosure of 
compensation arrangements was made both at the time of the Offering and at 
the time of exercise of the Warrants and (v) the solicitation of exercise of 
the Warrant was not in violation of Rule 10b-6 promulgated under the 
Securities Exchange Act of 1934, as amended. Rule 10b-6 may prohibit the 
Underwriter from engaging in any market making activities with regard to the 
Company's securities for the period from nine business days (or such other 
applicable period as Rule 10b-6 may provide) prior to any solicitation by the 
Underwriter of the exercise of Warrants until the later of the termination of 
such solicitation activity or the termination (by waiver or otherwise) of any 
right that the Underwriter may have to receive a fee for the exercise of 
Warrants following such solicitation. As a result, the Underwriter may be 
unable to provide a market for the Company's securities during certain 
periods while the Warrants are exercisable. 

   The Company has agreed to sell to the Underwriter and its designees, for 
nominal consideration, the Unit Purchase Option to purchase up to 310,000 
Units, substantially identical to the Units offered hereby, except that the 
Warrants included therein are not subject to redemption by the Company 
unless, on the redemption date, the Unit Purchase Option has been exercised 
and the underlying warrants are outstanding. The Unit Purchase Option will be 
exercisable during the four-year period commencing one year from the date of 
this Prospectus at an exercise price of $   per Unit, subject to adjustment 
in certain events, and is not transferable for a period of one year from the 
date of this Prospectus except to officers of the Underwriter or to members 
of the selling group. The Company has agreed to register during the four-year 
period commencing one year from the date of this Prospectus, on two separate 
occasions, the securities issuable upon exercise thereof under the Securities 
Act, the initial such registration to be at the Company's expense and the 
second at the expense of the holders. The Company has also granted certain 
piggy-back registration rights to holders of the Unit Purchase Option. The 
Unit Purchase Option includes a provision permitting the holders to elect a 
cashless exercise. 

   During the five-year period from the date of this Prospectus, in the event 
the Underwriter originates a financing or a merger, acquisition, joint 
venture, strategic introduction or other similar transaction to which the 
Company is a party, the Underwriter will be entitled to receive a finder's 
fee in consideration of the origination of such transaction. The fee is based 
upon a percentage of the consideration paid in the transaction. 

                                      68 
<PAGE>


   The Underwriter has informed the Company that it does not expect sales to 
discretionary accounts to exceed 5% percent of the total number of the Units 
offered hereby. 

   Prior to this Offering, there has been no public market for any of the 
securities offered hereby. Accordingly, the offering price of the Units 
offered hereby and the terms of the Warrants have been determined by 
negotiation between the Company and the Underwriter and are not necessarily 
related to the Company's asset value, net worth or other established criteria 
of value. Factors considered in determining such prices and terms, in 
addition to prevailing market conditions, include the history of and the 
prospects for the industry in which the Company competes, the present state 
of the Company's development and its future prospects, an assessment of the 
Company's management, the Company's capital structure, the general condition 
of the securities markets and such other factors as were deemed relevant. 


                                LEGAL MATTERS 


   The validity of the securities offered hereby will be passed upon for the 
Company by Baker & McKenzie, New York, New York. Certain legal matters 
related to this Offering will be passed upon for the Underwriter by Bachner, 
Tally, Polevoy & Misher LLP, New York, New York. Baker & McKenzie, New York, 
New York will rely, without independent verification, on the opinion of Baker 
& McKenzie, Zurich and Dr. Schackow & Partners, Bremen as to matters of Swiss 
and German law, respectively.

                                   GLOSSARY 

"Bytes" means a sequence of binary digits or bits which represents one piece 
of information such as a single letter. A byte is the unit of information 
processed by a computer. 

"Codec" means a combination of a coder and decoder. A coder uses a 
compression algorithm to reduce the number of bytes needed to represent an 
audio or video segment. A decoder recovers the original raw bytes from the 
compressed bytes generated by the coder. In video and audio compression, the 
recovery does not need to be exact; a good approximation of the original 
information is appropriate for practical purposes. 

"Compression algorithm" means a set of procedures (usually specified by 
mathematical equations) that reduce the number of bytes necessary to 
represent some piece of information, such as a video or audio segment. 

"Compression ratio" means the average number of bytes at the input of codec 
that will produce one byte at the output of the coder. The higher the ratio 
the lower the necessary channel speed to transmit the information, and 
therefore the lower the transmission cost. 

"CPU" means central processing unit. 

"ISDN" means integrated services digital network, an international switched 
digital communication network that provides multiples of 64 Kbps per channel, 
up to a maximum of 2 Mbps. ISDN is available in most countries from local 
telephone service providers and, in some cases, others. 

"Integrator" means a company which assembles third party components in 
systems. 

"Kbps" means kilobits per second, 1 Kbps equals 1,000 bits per second. 

"LAN" means Local Area Network, often a company computer network confined to 
one physical location. 

"Mbps" means megabits per second, 1 Mbps equals 1,000,000 bits per second. 

"OEM" means original equipment manufacturer. Such manufacturers often acquire 
components from outside suppliers which are then combined with the 
manufacturer's proprietary knowledge, hardware and/or software. 

"WAN" means Wide Area Network, often an enterprise computer network which 
ties a company's various physical locations together.

                         INDEPENDENT AUDITORS' REPORT 

To the Board of Directors and Stockholders 
IAT Multimedia, Inc. 

We have audited the accompanying consolidated balance sheets of IAT 
Multimedia, Inc. and Subsidiaries as of December 31, 1994 and 1995, and the 
related consolidated statements of operations, stockholders' equity (deficit) 
and cash flows for each of the three years in the period ended December 31, 
1995. These consolidated financial statements are the responsibility of the 
Company's management. Our responsibility is to express an opinion on these 
consolidated financial statements based on our audits. 

We conducted our audits in accordance with generally accepted auditing 
standards. Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether the financial statements are free 
of material misstatement. An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements. 
An audit also includes assessing the accounting principles used and 
significant estimates made by management, as well as evaluating the overall 
financial statement presentation. We believe that our audits provide a 
reasonable basis for our opinion. 

In our opinion, the consolidated financial statements referred to above 
present fairly, in all material respects, the financial position of IAT 
Multimedia, Inc. and Subsidiaries as of December 31, 1994 and 1995, and the 
results of their operations and their cash flows for each of the three years 
in the period ended December 31, 1995, in conformity with generally accepted 
accounting principles. 

The accompanying consolidated financial statements have been prepared 
assuming the Company will continue as a going concern. As discussed in Note 8 
to the consolidated financial statements, the Company has sustained recurring 
losses which raises substantial doubt about its ability to continue as a 
going concern. Management's plans in regard to these matters are also 
described in Note 8. The financial statements do not include any adjustments 
that might result from the outcome of this uncertainty.

                    IAT MULTIMEDIA, INC. AND SUBSIDIARIES 
                  NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 

NOTE 1. BUSINESS AND ORGANIZATION: 

   IAT Holdings, Inc. was incorporated under the laws of Delaware in 
September 1996 and changed its name to IAT Multimedia, Inc. ("IAT") in 
December 1996. During October 1996, IAT issued 4,375,000 shares of its common 
stock for 100% of the outstanding shares of common stock of IAT AG, a 
corporation organized under the laws of Switzerland, in a transaction 
accounted for as a pooling of interests. IAT develops, produces and sells 
desktop video conferencing communications systems mainly in Germany and 
Switzerland, and grants credit to a variety of businesses. 

NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES: 

   Principles of Consolidation -- The consolidated financial statements 
include the accounts of IAT, its wholly-owned subsidiary IAT AG, Switzerland, 
and a 74.9% owned subsidiary, IAT Deutschland GmbH Interaktive Mediem Systeme 
("IAT GmbH"), Bremen (collectively the "Company"). All intercompany accounts 
and transactions have been eliminated. 

   Inventories -- Inventories are valued at the lower of cost, on the 
first-in, first-out method (FIFO), or market. 

   Revenue Recognition -- Revenues from the sale of communications systems 
are recognized upon shipment to customers. Revenues from the rental of 
communications systems are recognized on a straight-line basis over the 
rental time period. 

   Use of Estimates -- The preparation of financial statements in conformity 
with generally accepted accounting principles requires management to make 
estimates and assumptions that affect the reported amounts of assets and 
liabilities and disclosure of contingent assets and liabilities at the date 
of the financial statements and the reported amounts of revenues and expenses 
during the reporting period. Actual results could differ from those 
estimates. 

   Equipment -- Equipment is stated at cost. Depreciation is provided using 
the straight-line method over the following estimated useful lives: 
  Telecommunications equipment              4 years 
  Office and data processing equipment      8 years 

   Deferred Registration Costs -- The Company has incurred costs relating to 
its proposed public offering (Note 8). If the offering is successful, these 
costs will be charged to capital in excess of par value, otherwise, the costs 
will be charged to operations. 

   Foreign Currency Translation -- The Company has determined that the local 
currency of its Switzerland subsidiary, Swiss Francs, is the functional 
currency. The financial statements of the subsidiaries have been translated 
into U.S. dollars in accordance with Statement of Financial Accounting 
Standards No. 52 (SFAS No. 52), "Foreign Currency Translation". SFAS No. 52 
provides that all balance sheet accounts are translated at year-end rates of 
exchange (1.31, 1.15 and 1.25 Swiss Francs for each U.S. Dollar at December 
31, 1994, 1995 and September 30, 1996, respectively), except for equity 
accounts which are translated at historical rates. Income and expense 
accounts are translated at the average of the exchange rates in effect during 
the period. The resulting translation adjustments are included as a separate 
component of stockholders' deficit, whereas gains or losses arising from 
foreign currency transactions are included in results of operations. 

   Fair Value of Financial Instruments -- The fair value of the Company's 
assets and liabilities which qualify as financial instruments under Statement 
of Financial Accounting Standards No. 107 approximate the carrying amounts 
presented in the consolidated balance sheets. 

   Stock Options -- In October 1995, the Financial Accounting Standards Board 
(FASB) issued Statement of Financial Accounting Standards No 123, "Accounting 
for Stock-Based Compensation" ("SFAS"). SFAS 123 requires compensation 
expense to be recorded (i) using the new fair value method or (ii) using 
existing account-

                                     F-7 
<PAGE>

ing rules prescribed by Accounting Principles Board Opinion No. 25, 
"Accounting for Stock Issued to Employees" ("APB 25") and related 
interpretations with pro forma disclosure of what net income and earnings per 
share would have been had the Company adopted the new fair value method. The 
Company intends to continue to account for its stock based compensation plans 
in accordance with the provisions of APB 25. 

   Income Taxes -- The Company complies with Statement of Financial 
Accounting Standards No. 109 (SFAS 109), "Accounting for Income Taxes", which 
requires an asset and liability approach to financial reporting for income 
taxes. Deferred income tax assets and liabilities are computed based on 
differences between financial reporting and tax bases of assets and 
liabilities that will result in taxable or deductible amounts in the future, 
based on enacted tax laws and rates applicable to the period in which the 
differences are expected to reverse. Valuation allowances are established, 
when necessary, to reduce the deferred income tax assets to the amount 
expected to be realized. 

   Research and Development Costs -- Research and development expenditures 
conducted for internal purposes are expensed as incurred. The expenditures 
include the following cost elements directly relating to research and 
development: materials costs, equipment and facilities depreciation, 
personnel costs, contract services and certain general and administrative 
expenses. Software development costs incurred subsequent to establishment of 
technological feasibility have not been material. 

   Loss Per Common Share -- Loss per share of common stock is based upon the 
weighted average number of shares outstanding, including common stock 
equivalents. Shares of common stock to be placed in escrow upon completion of 
the proposed public offering described in Note 12, which are common stock 
equivalents, have been excluded from the calculation of loss per share. The 
weighted average includes shares and common stock equivalents issued within 
one year of the Company's proposed initial public offering (IPO) with an 
issue price less than the anticipated IPO price (see Notes 8 and 12). In 
addition, all shares have been adjusted to reflect the reverse stock split 
discussed in Note 12. 

   Unaudited Consolidated Financial Statements -- The unaudited interim 
consolidated financial statements included herein have been prepared in 
accordance with generally accepted accounting principles. In the opinion of 
management, the unaudited consolidated financial statements include all 
adjustments of a normal and recurring nature, which are necessary for a fair 
presentation. The results of operations for the nine months are not 
necessarily indicative of the results expected for the full year. 

   Minority Interest in Consolidated Subsidiary -- The Company records 
minority interest in its consolidated subsidiary at the cost of the 
investment, adjusted for the applicable income (loss) from operations. Losses 
from operations, however, will be recorded only to the extent of the original 
investment and previously recognized equity in earnings, if any. 

   Research and Development Participation Agreements -- The Company has entered
into various agreements relating to the joint development of the Company's
products. In accordance with these agreements, the Company and its counterparts
each have rights for the use of the developed technology. Reimbursed research
and development costs for the years ended December 31, 1993, 1994, 1995 and the
nine months ended September 30, 1995 and 1996 were $962,028, $2,206,888,
$868,335, $584,550 and $272,071, respectively.

NOTE 8. UNCERTAINTY -- ABILITY TO CONTINUE AS A GOING CONCERN: 

   The consolidated financial statements have been prepared assuming the 
Company will continue as a going concern, which contemplates the realization 
of assets and the satisfaction of liabilities in the normal course of 
business. The Company has sustained recurring losses and has working capital 
and stockholders' deficits. The Company's subsidiaries are subject to German 
and Swiss law, which require, among other things, that companies which incur 
losses have to take appropriate measures to ensure that the claims of the 
Company's subsidiaries' obligees are covered by the assets of those 
respective subsidiaries. Such measures include, among others, increasing 
paid-in capital or obtaining declarations from the obligees which 
subordinates their claims. If those measures are not taken, the board of 
directors of the subsidiaries must notify a judge in order to commence 
bankruptcy proceedings which, under Swiss and German law, usually leads to 
the dissolution of the corporate existence. As of September 30, 1996 
(unaudited) the Company's subsidiaries have not filed for bankruptcy. 
Continuation of the Company as a going concern is dependent on its ability to 
resolve its liquidity problems and attain profitable operations. The 
consolidated financial statements do not include any adjustments that might 
result from the outcome of this uncertainty. 

   Management plans to raise equity capital and execute a letter of intent 
with an underwriter for an IPO on a Form S-1 Registration Statement.

NOTE 9. DEPENDENCE UPON KEY RELATIONSHIPS: 

   Approximately $1,686,000, $915,000, $1,032,000, $532,000 and $833,000 of 
the Company's revenues for the years ended December 31, 1993, 1994, 1995 and 
for the nine months ended September 30, 1995 (unaudited) and 1996 
(unaudited), respectively, were attributable to sales to one customer or 
affiliates of the customer. Sales for the years ended December 31, 1993, 
1994, 1995 and the nine months ended September 30, 1995 and 1996, 
respectively are from customers located in Switzerland and Germany. At 
December 31, 1994 and 1995 and September 30, 1996 substantially all of the 
Company's assets and liabilities were located in Germany and Switzerland. 

   The Company purchases several parts used in the production of its products 
from certain vendors, even where multiple sources are available in an effort 
to maintain quality control. The loss of any of these vendors could have a 
material adverse effect on the Company's operations until the Company can 
redesign its products or find an alternative source. 


NOTE 10. INCOME TAXES: 

   For the years ended December 31, 1993, 1994 and 1995 and the nine months 
ended September 30, 1995 (unaudited) and 1996 (unaudited), income taxes 
computed at the statutory federal rates differ from the Company's effective 
rate due to the change in the deferred tax asset valuation allowance. The 
Company, since inception, has not generated taxable income within any taxing 
jurisdiction in which the Company operates. 

   At December 31, 1995 and September 30, 1996 (unaudited), the Company has 
net operating loss carryforwards ("NOL") for Swiss and German income tax 
purposes of approximately $11,336,000 and $537,000 and $13,373,000 and 
$1,251,000, respectively. The Swiss NOLs expire between 1996 and 2002, and 
the German NOLs have no expiration date. As a result, at December 31, 1994, 
1995 and September 30, 1996 (unaudited), the Company recorded deferred tax 
assets of approximately $2,564,000, $3,669,000 and $4,638,000, respectively 
and valuation allowances in the same amounts relating principally to Swiss 
and German NOLs. 

   SFAS 109 requires that the Company record a valuation allowance when it is 
"more likely than not that some portion or all of the deferred tax asset will 
not be realized". The ultimate realization of this deferred tax asset depends 
on the ability to generate sufficient taxable income in the future. 

NOTE 11. COMMITMENTS AND CONTINGENCIES: 

   The Company has entered into operating leases for the use of office, 
manufacturing facilities and equipment. Rent expense for the years ended 
December 31, 1993, 1994 and 1995 and the nine months ended September 30, 1995 
(unaudited) and 1996 (unaudited) was approximately $238,000, $196,000, 
$306,000, $218,000 and $304,000 respectively. 

   Aggregate approximate future minimum rental payment under these operating 
leases are as follows: 

      Year Ending December 31, 
      ------------------------ 
               1996                              $  379,000 
               1997                                 339,000 
               1998                                 226,000 
               1999                                 204,000 
                                                ------------- 
                                                 $1,148,000 
                                                ============= 

   The Company currently does not maintain product liability insurance, and 
believes that it cannot obtain such insurance except at substantial cost. 
While no product liability claims have been made against the Company, there 
can be no assurance that such claims will not arise in the future. Any 
substantial uninsured liability would have a material adverse effect on the 
results of operations, cash flows or financial position of the Company. 


   The Company is a party to various legal actions, the outcome of which, in 
the opinion of management, will not have a material adverse effect on results 
of operations, cash flows or financial position of the Company.

NOTE 12. SUBSEQUENT EVENTS: 

   During October 1996, the Company issued 1,875,000 shares of Series A 
Convertible Preferred Stock, par value $.01 per share (Series A), for 
$1,500,000. The Series A stock is initially convertible into 1,875,000 shares 
of the Company's common stock, however, will automatically convert upon the 
consummation of the Company's proposed IPO under the Securities Act of 1933, 
as amended. Each share of Series A has voting rights equivalent to a common 
stockholder on an as converted basis. The Company is required to pay a 
dividend at a rate of $.056 per share for the first year and $.80 per share 
for each year thereafter. At any time after December 31, 1997, the Company 
has the option to redeem all outstanding shares of Series A, and the 
preferred stockholder has the option to require the Company to purchase all, 
or a portion, of the Series A shares at any time following the second 
anniversary of purchase, for an amount equal to the liquidation preference, 
as defined, currently $0.80 per share. In addition, the Company issued 
warrants to purchase 1,875,000 shares of common stock. The warrants are 
exercisable at a per share price equal to 130% of the IPO price per share, 
and expire at the earlier of the ten year anniversary date of the IPO, or 
December 31, 2006. 

   In connection with the sale of the Series A shares, the Company entered 
into a marketing agreement, with an affiliate of a Series A stockholder, to 
assist with marketing the Company's products worldwide, and to arrange 
financing for the Company's operations, leasing programs and distribution 
arrangements. The agreement terminates in October 2001. Compensation under 
the agreement is as follows: 

   $100,000 payable on the signing of the contract, $300,000 payable at such 
   time as the Company's consolidated stockholders' equity exceeds $6 
   million, and an additional $100,000 payable at such time the Company's 
   consolidated stockholders' equity exceeds $8 million, as defined. The 
   agreement may be terminated at any time after June 30, 1997, if the 
   Company's working capital does not exceed $4 million. 

   In connection with the issuance of the Company's common stock to certain 
former IAT AG stockholders, the Company issued warrants to purchase an 
aggregate of 473,485 shares of the Company's common stock. The warrants are 
exercisable at a per share price equal to 130% of the IPO price per share, 
and expire at the earlier of the ten year anniversary date of the IPO, or 
December 31, 2006. 

   During October and November 1996, certain stockholders loaned the Company an
aggregate of $920,000 bearing interest ranging from 8% to 10% per annum. The
Company will repay $400,000 of this loan from proceeds of the proposed IPO and
the remaining balance is due on January 1, 1998. The loan is subordinated to all
other creditor claims. In addition, approximately $120,000 of a stockholder loan
received during the nine months ended September 30, 1996 was repaid.

   In December 1996, the Company signed a letter of intent with an investment 
banking firm for the purpose of underwriting an IPO. 

   Certain of the Company's stockholders have agreed to place an aggregate of 
500,000 shares of the Company's common stock in escrow. These shares will not 
be assignable or transferable (but may be voted) until such time as they are 
released from escrow based upon the Company meeting certain annual revenue 
and or income levels or the common stock attaining certain price levels. All 
reserved shares remaining in escrow on March 31, 2000 will be forfeited and 
contributed to the Company's capital. In the event the Company attains any of 
the earnings thresholds or stock prices providing for the release of escrow 
shares to the stockholders, the Company will recognize compensation expense 
at such time based on the fair market value of the shares. 

   In December 1996, the Company's board of directors and stockholders 
approved the adoption of the Company's 1996 Stock Option Plan (the "1996 
Plan"). The 1996 Plan provides for a grant of a limited number of 
non-qualified and incentive stock options in respect of up to 500,000 shares 
of Common Stock to eligible employees and advisors. The 1996 Plan is 
administered by the Stock Option Committee consisting of the independent 
directors of the Company. Each option granted pursuant to the 1996 Plan is 
designated at the time of grant as either an incentive stock option or as a 
non-qualified stock option. 

   In December 1996, the Board of Directors and stockholders of the Company 
approved a reverse stock split whereby .947 shares of the common stock and 
preferred stock were issued for each share outstanding at that time. All 
share information in the consolidated financial statements have been restated 
to reflect such stock split. In addition, the Company increased the amount of 
authorized Preferred Stock $.01 par value, to 2,375,000 shares.

              PART II -- INFORMATION NOT REQUIRED IN PROSPECTUS

   The Certificate of Incorporation and By-Laws of the Registrant provide

145 of the GCL, relating to indemnification, is hereby incorporated herein by 
reference. 

   In accordance with Section 102(a)(7) of the GCL, the Certificate of 
Incorporation of the Registrant eliminates the personal liability of 
directors to the Registrant or its stockholders for monetary damages for 
breach of fiduciary duty as a director with certain limited exceptions set 
forth in Section 102(a)(7). 

   Reference is made to Section 6 of the Underwriting Agreement (Exhibit 1.1) 
which provides for indemnification by the Underwriter of the Registrant and 
its directors. 

ITEM 25. OTHER EXPENSES OF ISSUANCE AND DISTRIBUTION. 

   The estimated expenses payable by the Registrant in connection with the 
issuance and distribution of the securities being registered (other than

                                                                  Amount

ITEM 26. RECENT SALES OF UNREGISTERED SECURITIES. 

   In connection with its organization in October 1996, the Registrant 
exchanged 4,620,000 of its Common Stock and warrants to purchase 500,000 
shares of Common Stock for all of the issued and outstanding stock of IAT AG, 
a corporation organized under the laws of Switzerland. Since its 
organization, the Registrant has sold and issued the following unregistered 
securities: 

   In October 1996, the Registrant sold 1,980,000 shares of Series A 
Preferred Stock and warrants to purchase 1,980,000 shares of Common Stock to 
Vertical Financial Holdings, Behala Anstalt, Henilia Financial Limited, Lupin 
Investment Services Ltd. and Avi Suriel. 

   The above transactions were private transactions not involving a public 
offering and were exempt from the registration provisions of the Securities 
Act of 1933, as amended, pursuant to Section 4(2) thereof. The sale of 
securities was without the use of an underwriter, and the certificates 
evidencing the shares bear a restrictive legend permitting the transfer 
thereof only upon registration of the shares or an exemption under the 
Securities Act of 1933, as amended. 

   In December 1996, the Registrant effected a reverse stock split resulting 
in a reduction of its outstanding stock from 4,620,000 shares of Common Stock 
to 4,375,000 shares and from 1,980,000 shares of Series A Preferred Stock to 
1,875,000 shares. The Registrants outstanding Warrants were similarly 
effected.

ITEM 28. UNDERTAKINGS. 

   The undersigned registrant hereby undertakes: 

   (1) To file, during any period in which offers or sales are being made, a 
post-effective amendment to this registration statement: 

       (i)   to include any prospectus required by Section 10(a)(3) of the 
             Securities Act of 1933; 
       (ii)  to reflect in the prospectus any facts or events arising after 
             the effective date of the registration statement (or the most 
             recent post-effective amendment thereof) which, individually or 
             in the aggregate, represent a fundamental change in the 
             information set forth in the registration statement. 
             Notwithstanding the foregoing, any increase or decrease in volume 
             of securities offered (if the total dollar value of securities 
             offered would not exceed that which was registered) and any 
             deviation from the low or high end of the estimated maximum 
             offering range may be reflected in the form of prospectus filed 
             with the Commission pursuant to Rule 424(b) if, in the aggregate, 
             the changes in volume and price represent no more than a 20 
             percent change in the maximum aggregate offering price set forth 
             in the "Calculation of Registration Fee" table in the effective 
             registration statement; and 
       (iii) to include any material information with respect to the plan of 
             distribution not previously disclosed in the registration 
             statement or any material change to such information in the 
             registration statement. 

                                     II-3 
<PAGE>

   (2) That, for the purpose of determining any liability under the 
Securities Act of 1933, each such post-effective amendment shall be deemed 
to be a new registration statement relating to the securities offered 
therein, and the offering of such securities at that time shall be deemed to 
be the initial bona fide offering thereof. 

   The undersigned registrant hereby undertakes to provide to the underwriter 
at the closing specified in the underwriting agreements, certificates in such 
denominations and registered in such names as required by the underwriter to 
permit prompt delivery to each purchaser. 

   Insofar as indemnification for liabilities arising under the Securities 
Act of 1933 may be permitted to directors, officers and controlling persons 
of the registrant pursuant to the foregoing provisions, or otherwise, the 
registrant has been advised that in the opinion of the Securities and 
Exchange Commission such indemnification is against public policy as 
expressed in the Act, and is, therefore, unenforceable. In the event that a 
claim for indemnification against such liabilities (other than the payment by 
the registrant of expenses incurred or paid by a director, officer or 
controlling person of the registrant of expenses incurred or paid by a 
director, officer or controlling person of the registrant in the successful 
defense of any action, suit or proceeding) is asserted by such director, 
officer or controlling person in connection with the securities being 
registered, the registrant will, unless in the opinion of its counsel the 
matter has been settled by controlling precedent, submit to a court of 
appropriate jurisdiction the question whether such indemnification by it is 
against public policy as expressed in the Act and will be governed by the 
final adjudication of such issue. 

   The undersigned registrant hereby undertakes that: 

   (1) For purposes of determining any liability under the Securities Act of 
1933, the information omitted from the form of prospectus filed as part of 
the registration statement in reliance upon Rule 430A and contained in a form 
of prospectus filed by the registrant pursuant to Rule 424(b)(1) or (4) or 
497(h) under the Securities Act shall be deemed to be part of this 
registration statement as of the time it was declared effective; and 

   (2) For the purpose of determining any liability under the Securities Act 
of 1933, each post-effective amendment that contains a form of prospectus 
shall be deemed to be a new registration statement relating to the securities 
offered therein, and the offering of such securities at that time shall be 
deemed to be the initial bona fide offering thereto. 

                                     II-4

Royce Investment Group, Inc.                                              , 1997
 As Representative of the Several Underwriters
199 Crossways Park Drive
Woodbury, New York 11797

     IAT Multimedia, Inc., a Delaware corporation ( "IAT" or the "Company"),
proposes to issue and sell to the underwriters named in Schedule A (the
"Underwriters") of this Underwriting Agreement (the "Agreement"), for whom you
are acting as representative (the "Representative"), an aggregate of 3,100,000
Units, each unit being hereinafter referred to as a "Unit" and consisting of one
share of Common Stock, par value $.01 per share, ("Shares") and one redeemable
warrant ("Warrants") to purchase one share of Common Stock at a price of $___ at
any time from the Separation Date (as defined in the Warrant Agreement dated the
date hereof among the Company, the Representative and American Stock Transfer &
Trust Company to __________, 2002. The Warrants are subject to redemption, in
certain instances commencing 15 months from the date of this Agreement. In
addition, IAT proposes to grant to the Underwriters (or, at its option, the
Representative, individually) the option referred to in Section 2(b) to purchase
all or any part of an aggregate of 465,000 additional Units. Unless the context
otherwise indicates, the term "Units" shall include the 465,000 additional Units
referred to above.

     The aggregate of 3,100,000 Units to be sold by IAT, together with all or
any part of the 465,000 Units which the Underwriters have the option to
purchase, and the Shares and the Warrants comprising such Units, are herein
called the "Units." The Common Stock of IAT to be outstanding after giving
effect to the sale of the Shares is herein called the "Common Stock." The Shares
and Warrants included in the Units (including the Units which the Underwriters
have the option to purchase) are herein collectively called the "Securities."

     You have advised IAT that you and the other Underwriters desire to
purchase, severally, the Units, and that you have been authorized by the
Underwriters to execute this agreement on their behalf. IAT confirms the
agreements made by it with respect to the purchase of the Units by the several
Underwriters on whose behalf you are signing this Agreement, as follows:



                                      

<PAGE>



     1. Representations and Warranties of the Company. The Company represents
and warrants to, and agrees with, the Underwriters that:

          (a) A registration statement (File No. 333- ) on Form S-1 relating to
     the public offering of the Units, including a form of prospectus subject to
     completion, copies of which have heretofore been delivered to you, has been
     prepared by IAT in conformity with the requirements of the Securities Act
     of 1933, as amended (the "Act"), and the rules and regulations (the "Rules
     and Regulations") of the Securities and Exchange Commission (the
     "Commission") thereunder, and has been filed with the Commission under the
     Act and one or more amendments to such registration statement may have been
     so filed. After the execution of this Agreement, IAT will file with the
     Commission either (i) if such registration statement, as it may have been
     amended, has been declared by the Commission to be effective under the Act,
     either (A) if IAT relies on Rule 434 under the Act, a Term Sheet (as
     hereinafter defined) relating to the Units that shall identify the
     Preliminary Prospectus (as hereinafter defined) that it supplements
     containing such information as is required or permitted by Rules 434, 430A
     and 424(b) under the Act or (B) if IAT does not rely on Rule 434 under the
     Act a prospectus in the form most recently included in an amendment to such
     registration statement (or, if no such amendment shall have been filed, in
     such registration statement), with such changes or insertions as are
     required by Rule 430A under the Act or permitted by Rule 424(b) under the
     Act and in the case of either clause (i)(A) or (i)(B) of this sentence, as
     have been provided to and approved by the Representative prior to the
     execution of this Agreement, or (ii) if such registration statement, as it
     may have been amended, has not been declared by the Commission to be
     effective under the Act, an amendment to such registration statement,
     including a form of prospectus, a copy of which amendment has been
     furnished to and approved by the Representative prior to the execution of
     this Agreement.

          As used in this Agreement, the term "Registration Statement" means
     such registration statement, as amended at the time when it was or is
     declared effective, including all financial schedules and exhibits thereto
     and including any information omitted therefrom pursuant to Rule 430A under
     the Act and included in the Prospectus (as hereinafter defined); the term
     "Preliminary Prospectus" means each prospectus subject to completion filed
     with such registration statement or any amendment thereto (including the
     prospectus subject to completion, if any, included in the Registration
     Statement or any amendment thereto at the time it was or is declared
     effective); the term "Prospectus" means (A) if IAT relies on Rule 434 under
     the Act, the Term Sheet relating to the Units that is first filed pursuant
     to Rule 424(b)(7) under the Act, together with the Preliminary Prospectus
     identified therein that such Term Sheet supplements; (B) if IAT does not
     rely on Rule 434 under the Act, the prospectus first filed with the
     Commission pursuant to Rule 424(b) under the Act or (C) if IAT does not
     rely on Rule 434 under the Act and if no prospectus is required to be filed
     pursuant to said Rule 424(b), such term means the prospectus included in
     the Registration Statement; except that if such registration statement or
     prospectus is amended or such prospectus is supplemented, after the
     effective date of such registration statement and prior to the Option
     Closing Date (as hereinafter defined), the terms "Registration Statement"
     and "Prospectus" shall include such registration statement and prospectus
     as so amended, and the term "Prospectus" shall include the prospectus as so
     supplemented, or both, as the case may be; and the term "Term Sheet" means
     any term sheet that


                                       -2-

<PAGE>



     satisfies the requirements of Rule 434 under the Act. Any reference to the
     "date" of a Prospectus that includes a Term Sheet shall mean the date of
     such Term Sheet.

          (b) The Commission has not issued any order preventing or suspending
     the use of any Preliminary Prospectus. At the time the Registration
     Statement becomes effective and at all times subsequent thereto up to and
     on the Closing Date (as hereinafter defined) or the Option Closing Date, as
     the case may be, (i) the Registration Statement and Prospectus will in all
     respects conform to the requirements of the Act and the Rules and
     Regulations; and (ii) neither the Registration Statement nor the Prospectus
     will include any untrue statement of a material fact or omit to state any
     material fact required to be stated therein or necessary to make statements
     therein not misleading; provided, however, that IAT makes no
     representations, warranties or agreements as to information contained in or
     omitted from the Registration Statement or Prospectus in reliance upon, and
     in conformity with, written information furnished to IAT by or on behalf of
     the Underwriters specifically for use in the preparation thereof. It is
     understood that the statements set forth in the Prospectus on page 2 with
     respect to stabilization, under the heading "Underwriting" and the identity
     of counsel to the Underwriters under the heading "Legal Matters" constitute
     the only information furnished in writing by or on behalf of the several
     Underwriters for inclusion in the Registration Statement and Prospectus, as
     the case may be.

          (c) Each of IAT and IAT AG ("IAT AG") and IAT Deutschland GmbH
     Interactive Media Systeme ("IAT Germany" and together with IAT AG, the
     "Subsidiaries"), has been duly incorporated and is validly existing as a
     corporation in good standing under the laws of the jurisdiction of its
     incorporation, with full power and authority corporate and other to own its
     properties and conduct its business as described in the Prospectus and is
     duly qualified to do business as a foreign corporation and is in good
     standing in all other jurisdictions in which the nature of its business or
     the character or location of its properties requires such qualification,
     except where failure to so qualify will not materially affect IAT's or any
     of the Subsidiaries' business, properties or financial condition.

          (d) The authorized, issued and outstanding capital stock of IAT as of
     __________, 1996 is as set forth in the Prospectus under "Capitalization";
     the shares of issued and outstanding capital stock of IAT set forth
     thereunder have been duly authorized, validly issued and are fully paid and
     non-assessable; except as set forth in the Prospectus, no options,
     warrants, or other rights to purchase, agreements or other obligations to
     issue, or agreements or other rights to convert any obligation into, any
     shares of capital stock of IAT have been granted or entered into by IAT;
     and the capital stock conforms to all statements relating thereto contained
     in the Registration Statement and Prospectus.

          (e) The Units and the Shares are duly authorized, and when issued and
     delivered pursuant to this Agreement, will be duly authorized, validly
     issued, fully paid and nonassessable and free of preemptive rights of any
     security holder of IAT. Neither the filing of the Registration Statement
     nor the offering or sale of the Units as contemplated in this Agreement
     gives rise to any rights, other than those which have been waived or
     satisfied, for or


                                       -3-

<PAGE>



     relating to the registration of any shares of Common Stock, except as
     described in the Registration Statement.

          The Warrants have been duly authorized and, when issued and delivered
     pursuant to this Agreement, will have been duly executed, issued and
     delivered and will constitute valid and legally binding obligations of IAT
     enforceable in accordance with their terms and entitled to the benefits
     provided by the warrant agreement pursuant to which such Warrants are to be
     issued (the "Warrant Agreement"), which will be substantially in the form
     filed as an exhibit to the Registration Statement. The shares of Common
     Stock issuable upon exercise of the Warrants have been reserved for
     issuance upon the exercise of the Warrants and when issued in accordance
     with the terms of the Warrants and Warrant Agreement, will be duly and
     validly authorized, validly issued, fully paid and non-assessable and free
     of preemptive rights and no personal liability will attach to the ownership
     thereof. The Warrant Agreement has been duly authorized and, when executed
     and delivered pursuant to this Agreement, will have been duly executed and
     delivered and will constitute the valid and legally binding obligation of
     IAT enforceable in accordance with its terms. The Warrants and the Warrant
     Agreement conform to the respective descriptions thereof in the
     Registration Statement and Prospectus.

          The Shares and the Warrants contained in the Unit Purchase Option have
     been duly authorized and, when duly issued and delivered, such Warrants
     will constitute valid and legally binding obligations of IAT enforceable in
     accordance with their terms and entitled to the benefits provided by the
     Unit Purchase Option. The Shares included in the Unit Purchase Option (and
     the shares of Common Stock issuable upon exercise of such Warrants) when
     issued and sold, will be duly authorized, validly issued, fully paid and
     non-assessable and free of preemptive rights and no personal liability will
     attach to the ownership thereof.

          (f) This Agreement, the Unit Purchase Option, the Warrant Agreement,
     the Escrow Agreement and the Merger and Acquisition Agreement have been
     duly and validly authorized, executed and delivered by IAT. IAT has full
     power and lawful authority to authorize, issue and sell the Units to be
     sold by it hereunder on the terms and conditions set forth herein, and no
     consent, approval, authorization or other order of any governmental
     authority is required in connection with such authorization, execution and
     delivery or with the authorization, issue and sale of the Units or the Unit
     Purchase Option, except such as may be required under the Act or state
     securities laws.

          (g) IAT does not own, directly or indirectly, any capital stock or
     other equity ownership or proprietary interests in any other corporation,
     association, trust, partnership, joint venture or other entity other than
     the Subsidiaries.

          (h) Except as described in the Prospectus, neither the Company nor any
     of the Subsidiaries is in violation, breach or default of or under, and
     consummation of the transactions herein contemplated and the fulfillment of
     the terms of this Agreement will not conflict with, or result in a breach
     or violation of, any of the terms or provisions of, or constitute a default
     under, or result in the creation or imposition of any lien, charge or
     encumbrance upon


                                       -4-

     any of the property or assets of IAT or any of the Subsidiaries pursuant to
     the terms of any indenture, mortgage, deed of trust, loan agreement or
     other agreement or instrument to which IAT or any of the Subsidiaries is a
     party or by which IAT or any of the Subsidiaries may be bound or to which
     any of the property or assets of IAT or any of the Subsidiaries is subject,
     nor will such action result in any violation of the provisions of the
     articles of incorporation or the by-laws (or other organizational
     documents) of IAT or any of the Subsidiaries, as amended, or any statute or
     any order, rule or regulation applicable to IAT or any of the Subsidiaries
     of any court or of any regulatory authority or other governmental body
     having jurisdiction over IAT or any of the Subsidiaries.

          (i) Subject to the qualifications stated in the Prospectus, each of
     IAT and the Subsidiaries has good and marketable title to all properties
     and assets described in the Prospectus as owned by it, free and clear of
     all liens, charges, encumbrances or restrictions, except such as are not
     materially significant or important in relation to its business; all of the
     material leases and subleases under which IAT or any of the Subsidiaries is
     the lessor or sublessor of properties or assets or under which IAT or any
     of the Subsidiaries hold properties or assets as lessee or sublessee as
     described in the Prospectus are in full force and effect, and, except as
     described in the Prospectus, IAT and each of the Subsidiaries is not in
     default in any material respect with respect to any of the terms or
     provisions of any of such leases or subleases, and no claim has been
     asserted by anyone adverse to rights of IAT or any of the Subsidiaries as
     lessor, sublessor, lessee or sublessee under any of the leases or subleases
     mentioned above, or affecting or questioning the right of IAT or any of the
     Subsidiaries to continued possession of the leased or subleased premises or
     assets under any such lease or sublease except as described or referred to
     in the Prospectus; and IAT and each of the Subsidiaries owns or leases all
     such properties described in the Prospectus as are necessary to their
     operations as now conducted and, except as otherwise stated in the
     Prospectus, as proposed to be conducted as set forth in the Prospectus.

          (j) Rothstein, Kass & Company, P.C., who have given their reports on
     certain financial statements filed and to be filed with the Commission as a
     part of the Registration Statement, which are incorporated in the
     Prospectus, are with respect to the Company, independent public accountants
     as required by the Act and the Rules and Regulations.

          (k) The financial statements, together with related notes, set forth
     in the Prospectus (or if the Prospectus is not in existence, the most
     recent Preliminary Prospectus) present fairly the financial position and
     results of operations and changes in cash flow position of IAT and the
     Subsidiaries on the basis stated in the Registration Statement, at the
     respective dates and for the respective periods to which they apply. Said
     statements and related notes have been prepared in accordance with
     generally accepted accounting principles applied on a basis which is
     consistent during the periods involved. The information set forth under the
     captions "Dilution", "Capitalization", and "Selected Financial Data" in the
     Prospectus fairly present, on the basis stated in the Prospectus, the
     information included therein. The pro forma financial information filed as
     part of the Registration Statement or included in the Prospectus (or such
     preliminary prospectus) has been prepared in accordance with the
     Commission's rules and guidelines with


                                       -5-

<PAGE>



     respect to pro forma financial statements, and includes all adjustments
     necessary to present fairly the pro forma financial condition and results
     of operations at the respective dates and for the respective periods
     indicated and all assumptions used in preparing such pro forma financial
     statements are reasonable.

          (l) Subsequent to the respective dates as of which information is
     given in the Registration Statement and Prospectus (or, if the Prospectus
     is not in existence, the most recent Preliminary Prospectus), neither IAT
     nor any of the Subsidiaries has incurred any liabilities or obligations,
     direct or contingent, not in the ordinary course of business, or entered
     into any transaction not in the ordinary course of business, which is
     material to the business of IAT or any of the Subsidiaries, and there has
     not been any change in the capital stock of, or any incurrence of
     short-term or long-term debt by, the Company or any issuance of options,
     warrants or other rights to purchase the capital stock of the Company or
     any adverse change or any development involving, so far as the Company can
     now reasonably foresee a prospective adverse change in the condition
     (financial or other), net worth, results of operations, business, key
     personnel or properties of it which would be material to the business or
     financial condition of IAT or any of the Subsidiaries and neither IAT nor
     any of the Subsidiaries has become a party to, and neither the business nor
     the property of IAT or any of the Subsidiaries has become the subject of,
     any material litigation whether or not in the ordinary course of business.

          (m) Except as set forth in the Prospectus, there is not now pending
     or, to the knowledge of IAT, threatened, any action, suit or proceeding to
     which IAT or any of the Subsidiaries is a party before or by any court or
     governmental agency or body, which might result in any material adverse
     change in the condition (financial or other), business prospects, net
     worth, or properties of IAT or any of the Subsidiaries, nor are there any
     actions, suits or proceedings related to environmental matters or related
     to discrimination on the basis of age, sex, religion or race; and no labor
     disputes involving the employees of IAT or any of the Subsidiaries exist or
     are imminent which might be expected to adversely affect the conduct of the
     business, property or operations or the financial condition or results of
     operations of IAT or any of the Subsidiaries.

          (n) Except as disclosed in the Prospectus, IAT and each of the
     Subsidiaries have filed all necessary income and franchise tax returns with
     all federal, state, local and foreign governmental agencies and have paid
     all taxes shown as due thereon; and there is no tax deficiency which has
     been or to the knowledge of IAT might be asserted against IAT or any of the
     Subsidiaries.

          (o) IAT and each of the Subsidiaries have sufficient licenses, permits
     and other governmental authorizations currently required for the conduct of
     their business or the ownership of their properties as described in the
     Prospectus and are in all material respects complying therewith. To the
     best knowledge of IAT, none of the activities or business of IAT or any of
     the Subsidiaries are in violation of, or cause IAT or any of the
     Subsidiaries to violate, any law, rule, regulation or order of the United
     States, Switzerland or Germany or any state, county or locality, or of any
     agency or body of the United States, Switzerland or Germany or of any


                                       -6-

<PAGE>



     state, county or locality, the violation of which would have a material
     adverse impact upon the condition (financial or otherwise), business,
     property, prospective results of operations, or net worth of IAT or any of
     the Subsidiaries.

          (p) IAT and the Subsidiaries own or possess the right to use all
     patents, trademarks, trademark registrations, service marks, service mark
     registrations, trade names, copyrights, licenses, inventions, trade secrets
     and rights described in the Prospectus as being necessary for the conduct
     of their respective businesses, and neither IAT nor any of the Subsidiaries
     is aware of any claim to the contrary or any challenge by any other person
     to the rights of IAT and the Subsidiaries with respect to the foregoing.
     IAT's and the Subsidiaries' business as now conducted does not and will not
     infringe or conflict with in any material respect patents, trademarks,
     service marks, trade names, copyrights, trade secrets, licenses or other
     intellectual property or franchise right of any other person. Except as
     described in the Prospectus, no claim has been made against IAT or any of
     the Subsidiaries alleging the infringement by IAT or any of the
     Subsidiaries of any patent, trademark, service mark, trade name, copyright,
     trade secret, license in or other intellectual property right or franchise
     right of any person.

          (q) IAT and the Subsidiaries are insured by insurers of recognized
     financial responsibility against such losses and risks and in such amounts
     as are customary in the businesses in which they are engaged; and neither
     IAT nor any of the Subsidiaries has any reason to believe that it will not
     be able to renew its existing insurance coverage as and when such coverage
     expires or to obtain similar coverage from similar insurers as may be
     necessary to continue their respective businesses at a cost that would not
     have a material adverse affect upon the condition (financial or otherwise),
     business, property, prospective results of operations, or net worth of IAT
     or any of the Subsidiaries.

          (r) Neither IAT nor any of the Subsidiaries has, directly or
     indirectly, at any time (i) made any contributions to any candidate for
     political office, or failed to disclose fully any such contribution in
     violation of law or (ii) made any payment to any state, federal or foreign
     governmental officer or official, or other person charged with similar
     public or quasi-public duties, other than payments or contributions
     required or allowed by applicable law. IAT's and the Subsidiaries' internal
     accounting controls and procedures are sufficient to cause IAT and the
     Subsidiaries to comply in all material respects with the Foreign Corrupt
     Practices Act of 1977, as amended.

          (s) On the Closing Dates (hereinafter defined) all transfer or other
     taxes, (including franchise, capital stock or other tax, other than income
     taxes, imposed by any jurisdiction) if any, which are required to be paid
     in connection with the sale and transfer of the Units to the several
     Underwriters hereunder will have been fully paid or provided for by IAT and
     all laws imposing such taxes will have been fully complied with.



                                       -7-

<PAGE>



          (t) All contracts and other documents of IAT or any of the
     Subsidiaries which are, under the Rules and Regulations, required to be
     filed as exhibits to the Registration Statement have been so filed.

          (u) Neither IAT nor any of the Subsidiaries has taken nor will take,
     directly or indirectly, any action designed to cause or result in, or which
     has constituted or which might reasonably be expected to constitute, the
     stabilization or manipulation of the price of the shares of Common Stock to
     facilitate the sale or resale of the Units hereby.

          (v) Neither IAT nor any of the Subsidiaries has entered into any
     agreement pursuant to which any person is entitled either directly or
     indirectly to compensation from IAT or any of the Subsidiaries for services
     as a finder in connection with the proposed public offering.

          (w) Except as previously disclosed in writing by IAT to the
     Representative, no officer, director or stockholder of IAT or any of the
     Subsidiaries has any affiliation or association with any member of the
     National Association of Securities Dealers Inc. ("NASD").

          (x) Neither IAT nor any of the Subsidiaries is, nor upon receipt of
     the proceeds from the sale of the Units will be, an "investment company"
     within the meaning of the Investment Company Act of 1940, as amended, and
     the rules and regulations thereunder.

          (y) Neither IAT nor any of the Subsidiaries has distributed nor will
     they distribute prior to the First Closing Date (as hereinafter defined)
     any offering material in connection with the offering and sale of the Units
     other than the Preliminary Prospectus, Prospectus, the Registration
     Statement or the other materials permitted by the Act, if any.

          (z) There are no business relationships or related-party transactions
     of the nature described in Item 404 of Regulation S-K involving IAT or any
     of the Subsidiaries and any person described in such Item that are required
     to be disclosed in the Prospectus (or, if the Prospectus is not in
     existence, the most recent Preliminary Prospectus) and that have not been
     so disclosed.

          (aa) IAT and each of the Subsidiaries have complied with all
     provisions of Section 517.075 Florida Statutes relating to doing business
     with the government of Cuba or with any person or affiliate located in
     Cuba.

     2. Purchase, Delivery and Sale of the Units.

          (a) Subject to the terms and conditions of this Agreement, and upon
     the basis of the representations, warranties, and agreements herein
     contained, IAT agrees to issue and sell to the Underwriters, and each such
     Underwriter agrees, severally and not jointly, to buy from IAT at $_______
     per Unit, at the place and time hereinafter specified, the number of Units


                                       -8-

<PAGE>



     set forth opposite the names of the Underwriters in Schedule A attached
     hereto (the "First Units") plus any additional Units which such
     Underwriters may become obligated to purchase pursuant to the provisions of
     Section 9 hereof. The First Units shall consist of 3,100,000 Units to be
     purchased from IAT.

          Delivery of the First Units against payment therefor shall take place
     at the offices of Royce Investment Group, Inc., 199 Crossways Park Drive,
     Woodbury, N.Y. (or at such other place as may be designated by agreement
     between you and IAT) at 10:00 a.m., New York time, on _____________, 1997,
     or at such later time and date as you may designate, such time and date of
     payment and delivery for the First Units being herein called the "First
     Closing Date."

          (b) In addition, subject to the terms and conditions of this
     Agreement, and upon the basis of the representations, warranties and
     agreements herein contained, IAT hereby grants an option to the several
     Underwriters to purchase all or any part of an aggregate of an additional
     465,000 Units at the same price per Unit as the Underwriters shall pay for
     the First Units being sold pursuant to the provisions of subsection (a) of
     this Section 2 (such additional Units being referred to herein as the
     "Option Units"). This option may be exercised within 45 days after the
     effective date of the Registration Statement upon notice by the
     Representative to IAT advising as to the amount of Option Units as to which
     the option is being exercised, the names and denominations in which the
     certificates for such Option Units are to be registered and the time and
     date when such certificates are to be delivered. Such time and date shall
     be determined by the Representative but shall not be earlier than four nor
     later than ten full business days after the exercise of said option, nor in
     any event prior to the First Closing Date, and such time and date is
     referred to herein as the "Option Closing Date." Delivery of the Option
     Units against payment therefor shall take place at the offices of Royce
     Investment Group, Inc., 199 Crossways Park Drive, Woodbury, N.Y. The number
     of Option Units to be purchased by each Underwriter, if any, shall bear the
     same percentage to the total number of Option Units being purchased by the
     several Underwriters pursuant to this subsection (b) as the number of Units
     such Underwriter is purchasing bears to the total number of the First Units
     being purchased pursuant to subsection (a) of this Section 2, as adjusted,
     in each case by the Representative in such manner as the Representative may
     deem appropriate. The option granted hereunder may be exercised only to
     cover overallotments in the sale by the Underwriters of First Units
     referred to in subsection (a) above. In the event IAT declares or pays a
     dividend or distribution on its Common Stock, whether in the form of cash,
     shares of Common Stock or any other consideration, prior to the Option
     Closing Date, such dividend or distribution shall also be paid on the
     Option Units on the Option Closing Date.

          (c) IAT will make the certificates for the securities comprising the
     Units to be purchased by the Underwriters hereunder available to you for
     checking at least two full business days prior to the First Closing Date or
     the Option Closing Date (which are collectively referred to herein as the
     "Closing Dates"). The certificates shall be in such names and denominations
     as you may request, at least two full business days prior to the Closing
     Dates.


                                       -9-

<PAGE>



     Time shall be of the essence and delivery at the time and place specified
     in this Agreement is a further condition to the obligations of each
     Underwriter.

          Definitive certificates in negotiable form for the Units to be
     purchased by the Underwriters hereunder will be delivered by IAT to you for
     the accounts of the several Underwriters against payment of the respective
     purchase prices by the several Underwriters, by certified or bank cashier's
     checks in New York Clearing House funds, payable to the order of IAT.

          In addition, in the event the Underwriters exercise the option to
     purchase from IAT all or any portion of the Option Units pursuant to the
     provisions of subsection (b) above, payment for such Units shall be made to
     or upon the order of IAT by certified or bank cashier's checks payable in
     New York Clearing House funds at the offices of Royce Investment Group,
     Inc., 199 Crossways Park Drive, Woodbury, New York, 11797 (or such other
     place as may be designated by agreement between you and IAT) at the time
     and date of delivery of such Units as required by the provisions of
     subsection (b) above, against receipt of the certificates for such Units by
     the Representative for the respective accounts of the several Underwriters
     registered in such names and in such denominations as the Representative
     may request.

          It is understood that you, individually and not as Representative of
     the several Underwriters, may (but shall not be obligated to) make any and
     all payments required pursuant to this Section 2 on behalf of any
     Underwriters whose check or checks shall not have been received by the
     Representative at the time of delivery of the Units to be purchased by such
     Underwriter or Underwriters. Any such payment by you shall not relieve any
     such Underwriter or underwriters of any of its or their obligations
     hereunder. It is also understood that you individually rather than all of
     the Underwriters may (but shall not be obligated to) purchase the Option
     Units referred to in subsection (b) of this Section 2, but only to cover
     overallotments.

          It is understood that the several Underwriters propose to offer the
     Units to be purchased hereunder to the public upon the terms and conditions
     set forth in the Registration Statement, after the Registration Statement
     becomes effective.

     3. Covenants of the Company. The Company covenants and agrees with the
several Underwriters that:

          (a) IAT will use its best efforts to cause the Registration Statement
     to become effective as promptly as possible. If required, IAT will file the
     Prospectus or any Term Sheet that constitutes a part thereof and any
     amendment or supplement thereto with the Commission in the manner and
     within the time period required by Rules 434 and 424(b) under the Act. Upon
     notification from the Commission that the Registration Statement has become
     effective, IAT will so advise you and will not at any time, whether before
     or after the effective date, file the Prospectus, Term Sheet or any
     amendment to the Registration Statement or supplement to the Prospectus of
     which you shall not previously have been advised and furnished with a copy
     or to which you or your counsel shall have objected in writing or which is
     not in


                                      -10-

<PAGE>



     compliance with the Act and the Rules and Regulations. At any time prior to
     the later of (A) the completion by all of the Underwriters of the
     distribution of the Units contemplated hereby (but in no event more than
     nine months after the date on which the Registration Statement shall have
     become or been declared effective) and (B) 25 days after the date on which
     the Registration Statement shall have become or been declared effective,
     IAT will prepare and file with the Commission, promptly upon your request,
     any amendments or supplements to the Registration Statement or Prospectus
     which, in your opinion, may be necessary or advisable in connection with
     the distribution of the Units.

          As soon as IAT is advised thereof, IAT will advise you, and confirm
     the advice in writing, of the receipt of any comments of the Commission, of
     the effectiveness of any post-effective amendment to the Registration
     Statement, of the filing of any supplement to the Prospectus or any amended
     Prospectus, of any request made by the Commission for amendment of the
     Registration Statement or for supplementing of the Prospectus or for
     additional information with respect thereto, of the issuance by the
     Commission or any state or regulatory body of any stop order or other order
     or threat thereof suspending the effectiveness of the Registration
     Statement or any order preventing or suspending the use of any preliminary
     prospectus, or of the suspension of the qualification of the Units for
     offering in any jurisdiction, or of the institution of any proceedings for
     any of such purposes, and will use its best efforts to prevent the issuance
     of any such order, and, if issued, to obtain as soon as possible the
     lifting thereof.

          IAT has caused to be delivered to you copies of each Preliminary
     Prospectus, and IAT has consented and hereby consents to the use of such
     copies for the purposes permitted by the Act. IAT authorizes the
     Underwriters and dealers to use the Prospectus in connection with the sale
     of the Units for such period as in the opinion of counsel to the several
     Underwriters the use thereof is required to comply with the applicable
     provisions of the Act and the Rules and Regulations. In case of the
     happening, at any time within such period as a Prospectus is required under
     the Act to be delivered in connection with sales by an underwriter or
     dealer of any event of which IAT has knowledge and which materially affects
     IAT or the securities of IAT, or which in the opinion of counsel for IAT or
     counsel for the Underwriters should be set forth in an amendment of the
     Registration Statement or a supplement to the Prospectus in order to make
     the statements therein not then misleading, in light of the circumstances
     existing at the time the Prospectus is required to be delivered to a
     purchaser of the Units or in case it shall be necessary to amend or
     supplement the Prospectus to comply with law or with the Rules and
     Regulations, IAT will notify you promptly and forthwith prepare and furnish
     to you copies of such amended Prospectus or of such supplement to be
     attached to the Prospectus, in such quantities as you may reasonably
     request, in order that the Prospectus, as so amended or supplemented, will
     not contain any untrue statement of a material fact or omit to state any
     material facts necessary in order to make the statements in the Prospectus,
     in the light of the circumstances under which they are made, not
     misleading. The preparation and furnishing of any such amendment or
     supplement to the Registration Statement or amended Prospectus or
     supplement to be attached to the Prospectus shall be without expense to the
     Underwriters, except that in case any Underwriter is required, in
     connection with the sale of the Units to deliver a


                                      -11-

<PAGE>



     Prospectus nine months or more after the effective date of the Registration
     Statement, IAT will upon request of and at the expense of the Underwriter,
     amend or supplement the Registration Statement and Prospectus and furnish
     the Underwriter with reasonable quantities of prospectuses complying with
     Section 10(a)(3) of the Act.

          The Company will comply with the Act, the Rules and Regulations and
     the Securities Exchange Act of 1934, as amended (the "Exchange Act") and
     the rules and regulations thereunder in connection with the offering and
     issuance of the Units.

          (b) IAT will use its best efforts to qualify to register the Units for
     sale under the securities or "blue sky" laws of such jurisdictions as the
     Representative may designate and will make such applications and furnish
     such information as may be required for that purpose and to comply with
     such laws, provided IAT shall not be required to qualify as a foreign
     corporation or a dealer in securities or to execute a general consent of
     service of process in any jurisdiction in any action other than one arising
     out of the offering or sale of the Units. IAT will, from time to time,
     prepare and file such statements and reports as are or may be required to
     continue such qualification in effect for so long a period as the
     Underwriters may reasonably request.

          (c) If the sale of the Units provided for herein is not consummated
     for any reason caused by the Company, IAT shall pay all costs and expenses
     incident to the performance of IAT's obligations hereunder, including but
     not limited to, all of the expenses itemized in Section 8, including the
     accountable expenses of the Representative.

          (d) IAT will use its best efforts to (i) cause a registration
     statement under the Exchange Act to be declared effective concurrently with
     the completion of this offering and will notify the Representative in
     writing immediately upon the effectiveness of such registration statement,
     and (ii) if requested by the Representative, to obtain a listing on the
     Pacific Stock Exchange and to obtain and keep current a listing in the
     Standard & Poors or Moody's Industrial OTC Manual.

          (e) For so long as IAT is a reporting company under either Section
     12(g) or 15(d) of the Exchange Act, IAT, at its expense, will furnish to
     its stockholders an annual report (including financial statements audited
     by independent public accountants), in reasonable detail and at its
     expense, will furnish to you during the period ending five (5) years from
     the date hereof, (i) as soon as practicable after the end of each fiscal
     year, a balance sheet of IAT and any of its subsidiaries as at the end of
     such fiscal year, together with statements of income, surplus and cash flow
     of IAT and any of its subsidiaries for such fiscal year, all in reasonable
     detail and accompanied by a copy of the certificate or report thereon of
     independent accountants; (ii) as soon as practicable after the end of each
     of the first three fiscal quarters of each fiscal year, consolidated
     summary financial information of IAT for such quarter in reasonable detail;
     (iii) as soon as they are available, a copy of all reports (financial or
     other) mailed to security holders; (iv) as soon as they are available, a
     copy of all non-confidential reports and financial statements furnished to
     or filed with the Commission or any securities exchange or automated
     quotation


                                      -12-

<PAGE>



     system on which any class of securities of IAT is listed; and (v) such
     other information as you may from time to time reasonably request.

          (f) In the event IAT has an active subsidiary or subsidiaries, such
     financial statements referred to in subsection (e) above will be on a
     consolidated basis to the extent the accounts of IAT and its subsidiary or
     subsidiaries are consolidated in reports furnished to its stockholders
     generally.

          (g) IAT will deliver to you at or before the First Closing Date two
     signed copies of the Registration Statement including all financial
     statements and exhibits filed therewith, and of all amendments thereto, and
     will deliver to the several Underwriters such number of conformed copies of
     the Registration Statement, including such financial statements but without
     exhibits, and of all amendments thereto, as the several Underwriters may
     reasonably request. IAT will deliver to you or upon the order of the
     several Underwriters, from time to time until the effective date of the
     Registration Statement, as many copies of any Preliminary Prospectus filed
     with the Commission prior to the effective date of the Registration
     Statement as the Underwriters may reasonably request. IAT will deliver to
     the Underwriters on the effective date of the Registration Statement and
     thereafter for so long as a Prospectus is required to be delivered under
     the Act, from time to time, as many copies of the Prospectus, in final
     form, or as thereafter amended or supplemented, as the Underwriters may
     from time to time reasonably request. IAT, not later than (i) 5:00 p.m.,
     New York City time, on the date of determination of the public offering
     price, if such determination occurred at or prior to 12:00 noon, New York
     City time, on such date or (ii) 6:00 p.m., New York City time, on the
     business day following the date of determination of the public offering
     price, if such determination occurred after 12:00 noon, New York City time,
     on such date, will deliver to the Underwriters, without charge, as many
     copies of the Prospectus and any amendment or supplement thereto as the
     Underwriters may reasonably request for purposes of confirming orders that
     are expected to settle on the First Closing Date.

          (h) IAT will make generally available to its security holders and to
     the registered holders of its Warrants and deliver to you as soon as it is
     practicable to do so but in no event later than 90 days after the end of
     twelve months after its current fiscal quarter, an earnings statement
     (which need not be audited) covering a period of at least 12 consecutive
     months beginning after the effective date of the Registration Statement,
     which shall satisfy the requirements of Section 11(a) of the Act.

          (i) IAT will apply the net proceeds from the sale of the Units for the
     purposes set forth under "Use of Proceeds" in the Prospectus, and will file
     such reports with the Commission with respect to the sale of the Units and
     the application of the proceeds therefrom as may be required pursuant to
     Rule 463 under the Act.

          (j) IAT will, promptly upon your request, prepare and file with the
     Commission any amendments or supplements to the Registration Statement,
     Preliminary Prospectus or Prospectus and take any other action, which in
     the reasonable opinion of Bachner,


                                      -13-

<PAGE>



     Tally, Polevoy & Misher LLP, counsel to the several Underwriters, may be
     reasonably necessary or advisable in connection with the distribution of
     the Units, and will use its best efforts to cause the same to become
     effective as promptly as possible.

          (k) IAT will reserve and keep available that maximum number of its
     authorized but unissued securities which are issuable upon exercise of the
     Warrants and the Unit Purchase Options outstanding from time to time.

          (l) The Company will deliver to the Representative agreements to the
     effect that for a period of 24 months from the First Closing Date, no
     officer, director or existing stockholder of IAT (such officers, directors
     and stockholders being herein referred to as the "Principal Stockholders"),
     will directly or indirectly, offer, sell (including any short sale), grant
     any option for the sale of, acquire any option to dispose of, or otherwise
     dispose of any securities of IAT. In order to enforce this covenant, IAT
     shall impose stop-transfer instructions with respect to the securities
     owned by the Principal Stockholders until the end of such period.

          (m) Prior to completion of this offering, IAT will make all filings
     required, including registration under the Exchange Act, to obtain the
     listing of the Units, Common Stock, and Warrants on the Nasdaq National
     Market (or a listing on such other market or exchange as the Underwriters
     consent to), and will effect and maintain such listing for at least five
     years from the date of this Agreement.

          (n) IAT and each of the Principal Stockholders represents that it or
     he has not taken and agree that it or he will not take, directly or
     indirectly, any action designed to or which has constituted or which might
     reasonably be expected to cause or result in the stabilization or
     manipulation of the price of the Units, Shares or the Warrants or to
     facilitate the sale or resale of the Securities.

          (o) On the Closing Date and simultaneously with the delivery of the
     Units, IAT shall execute and deliver to you, individually and not as
     representative of the Underwriters, the Unit Purchase Options. The Unit
     Purchase Options will be substantially in the form of the Representative's
     Unit Purchase Option filed as an Exhibit to the Registration Statement.

          (p) During the 18 month period commencing on the date of this
     Agreement, IAT will not, without the prior written consent of the
     Representative, grant options to purchase shares of Common Stock at an
     exercise price less than the greater of (i) the initial public offering
     price of the Units (without allocating any value to the Warrants) or (ii)
     the fair market value of the Common Stock on the date of grant. During the
     six month period commencing on the date of this Agreement, IAT will not,
     without the prior written consent of the Representative, grant options to
     any current officer of IAT[, or to any individual who will become an
     officer of IAT upon the First Closing Date]. During the three year period
     from the First Closing Date, IAT will not, without the prior written
     consent of the Representative, offer or sell any of its securities pursuant
     to Regulation S under the Act.


                                      -14-

<PAGE>



          (q) IAT will not, without the prior written consent of the
     Representative, grant registration rights to any person which are
     exercisable sooner than 13 months from the First Closing Date.

          (r) Dr. Viktor Vogt shall be Co-Chairman of the Board, Chief Executive
     Officer and President of IAT and Klaus Grissemann shall be the Chief
     Financial Officer and a director of IAT on the Closing Dates. IAT has
     obtained key person life insurance in an amount of not less than $2 million
     on the life of Dr. Viktor Vogt and such other individuals as designated by
     the Representative, and will use its best efforts to maintain such
     insurance during the three year period commencing with the First Closing
     Date. In the event that Dr. Vogt's employment with IAT is terminated prior
     to three years following the First Closing Date, IAT will obtain a
     comparable policy on the life of his successor for the balance of the three
     year period. For a period of thirteen months from the First Closing Date,
     the compensation of the executive officers of IAT shall not be increased
     from the compensation levels disclosed in the Prospectus.

          (s) So long as any Warrants are outstanding, IAT shall use its best
     efforts to cause post-effective amendments to the Registration Statement to
     become effective in compliance with the Act and without any lapse of time
     between the effectiveness of any such post-effective amendments and cause a
     copy of each Prospectus, as then amended, to be delivered to each holder of
     record of a Warrant and to furnish to each Underwriter and dealer as many
     copies of each such Prospectus as such Underwriter or dealer may reasonably
     request. IAT shall not call for redemption any of the Warrants unless a
     registration statement covering the securities underlying the Warrants has
     been declared effective by the Commission and remains current at least
     until the date fixed for redemption. In addition, for so long as any
     Warrant is outstanding, IAT will promptly notify the Representative of any
     material change in the business, financial condition or prospects of IAT or
     any of the Subsidiaries.

          (t) Upon the exercise of any Warrant or Warrants after ___________,
     1998, IAT will pay Royce Investment Group, Inc., in its individual capacity
     and not as Representative of the Underwriters, a fee (the "Solicitation
     Fee") of 6% of the aggregate exercise price of the Warrants if (i) the
     market price of IAT's Common Stock is greater than the exercise price of
     the Warrants on the date of exercise; (ii) the exercise of the Warrant was
     solicited by a member ("Member") of the National Association of Securities
     Dealers, Inc., (iii) the Warrant is not held in a discretionary account;
     (iv) the disclosure of compensation arrangements has been made in documents
     provided to customers, both as part of the original offering and at the
     time of exercise, and (v) the solicitation of the Warrant was not in
     violation of Rule 10b-6 promulgated under the Securities Exchange Act of
     1934, as amended. IAT agrees not to solicit the exercise of any Warrants
     other than through Royce Investment Group, Inc. and will not authorize any
     other dealer to engage in such solicitation without the prior written
     consent of Royce Investment Group, Inc. The Solicitation Fee shall only be
     payable to the extent that the Representative (or Member) who solicited the
     exercise of any warrant is designated in writing by the holder of the
     warrant as having solicited the exercise of such warrant.



                                      -15-

<PAGE>



          (u) For a period of five (5) years from the Effective Date IAT (i) at
     its expense, shall cause its regularly engaged independent certified public
     accountants to review (but not audit) IAT's financial statements for each
     of the first three (3) fiscal quarters prior to the announcement of
     quarterly financial information, the filing of IAT's 10-Q quarterly report
     and the mailing of quarterly financial information to stockholders and (ii)
     shall not change its accounting firm without the prior written consent of
     the Chairman or the President of the Representative.

          (v) As promptly as practicable after the Closing Date, IAT will
     prepare, at its own expense, hard cover "bound volumes" relating to the
     offering, and will distribute at least four of such volumes to the
     individuals designated by the Representative or counsel to the
     Underwriters.

          (w) For a period of five years from the First Closing Date (i) the
     Representative shall have the right, but not the obligation, to designate a
     director to the Board of Directors of IAT and (ii) IAT shall engage a
     public relations firm acceptable to the Underwriter.

          (x) IAT shall, for a period of six years after date of this Agreement,
     submit which reports to the Secretary of the Treasury and to stockholders,
     as the Secretary may require, pursuant to Section 1202 of the Internal
     Revenue Code, as amended, or regulations promulgated thereunder, in order
     for IAT to qualify as a "small business" so that stockholders may realize
     special tax treatment with respect to their investment in IAT.

          (y) Except for the use of net proceeds from the sale of the Units for
     the repayment of up to an aggregate of $1,250,000 of outstanding loans owed
     to Mr. Klaus-Dirk Sippel and Mr. Volker Walther, none of the net proceeds
     from the sale of the Units will be used to repay any obligations owed by
     IAT to any Principal Stockholder.

     4. Conditions of Underwriters' Obligation. The obligations of the several
Underwriters to purchase and pay for the Units which they have respectively
agreed to purchase hereunder, are subject to the accuracy (as of the date
hereof, and as of the Closing Dates) of and compliance with the representations
and warranties of IAT herein, to the performance by IAT of its obligations
hereunder, and to the following conditions:

          (a) The Registration Statement shall have become effective and you
     shall have received notice thereof not later than 10:00 A.M., New York
     time, on the date on which the amendment to the registration statement
     originally filed with respect to the Units or to the Registration
     Statement, as the case may be, containing information regarding the initial
     public offering price of the Units has been filed with the Commission, or
     such later time and date as shall have been agreed to by the
     Representative; if required, the Prospectus or any Term Sheet that
     constitutes a part thereof and any amendment or supplement thereto shall
     have been filed with the Commission in the manner and within the time
     period required by Rule 434 and 424(b) under the Act; on or prior to the
     Closing Dates no stop order suspending the effectiveness of the
     Registration Statement shall have been issued and no proceedings for that
     or a similar purpose


                                      -16-

<PAGE>



     shall have been instituted or shall be pending or, to your knowledge or to
     the knowledge of IAT, shall be contemplated by the Commission; any request
     on the part of the Commission for additional information shall have been
     complied with to the reasonable satisfaction of Bachner, Tally, Polevoy &
     Misher LLP, counsel to the several Underwriters;

          (b) At the First Closing Date, you shall have received the opinions,
     addressed to the Underwriters, dated as of the First Closing Date, of Baker
     & McKenzie, New York, counsel for IAT, and, with respect to matters of
     foreign law, the opinion of Baker & McKenzie, Zurich, counsel for IAT AG
     and Dr. Schackow & Partners, Bremen, counsel for IAT Germany, in form and
     substance satisfactory to counsel for the Underwriters, to the effect that:

               (i) Each of IAT and Subsidiaries has been duly incorporated and
          is validly existing as a corporation in good standing under the laws
          of the jurisdiction of its incorporation, with full corporate power
          and authority to own its properties and conduct its business as
          described in the Registration Statement and Prospectus and is duly
          qualified or licensed to do business as a foreign corporation and is
          in good standing in each jurisdiction in which the ownership or
          leasing of its properties or conduct of its business requires such
          qualification;

               (ii) to the best knowledge of such counsel, (a) each of IAT and
          the Subsidiaries has obtained, or is in the process of obtaining, all
          licenses, permits and other governmental authorizations necessary to
          the conduct of its business as described in the Prospectus, (b) such
          licenses, permits and other governmental authorizations obtained are
          in full force and effect, and (c) each of IAT and the Subsidiaries is
          in all material respects complying therewith;

               (iii) the authorized capitalization of IAT as of
          _________________, 1996 is as set forth under "Capitalization" in the
          Prospectus; all shares of IAT's outstanding stock requiring
          authorization for issuance by IAT's board of directors have been duly
          authorized, validly issued, are fully paid and non-assessable and
          conform to the description thereof contained in the Prospectus; the
          outstanding shares of Common Stock of IAT have not been issued in
          violation of the preemptive rights of any shareholder and the
          shareholders of IAT do not have any preemptive rights or other rights
          to subscribe for or to purchase, nor are there any restrictions upon
          the voting or transfer of any of the Stock; the Common Stock, the
          Warrants, the Unit Purchase Option and the Warrant Agreement conform
          to the respective descriptions thereof contained in the Prospectus;
          the Shares have been, and the shares of Common Stock to be issued upon
          exercise of the Warrants and the Unit Purchase Option, upon issuance
          in accordance with the terms of such Warrants, the Warrant Agreement
          and Unit Purchase Option have been duly authorized and, when issued
          and delivered, will be duly and validly issued, fully paid,
          non-assessable, free of preemptive rights and no personal liability
          will attach to the ownership thereof; all prior sales by IAT of IAT's
          securities have been made in compliance with or under an exemption
          from registration under the Act and applicable state securities laws
          and no shareholders of IAT have any rescission rights with respect to
          Company securities; a sufficient number of shares of Common Stock has
          been reserved for issuance upon exercise of the


                                      -17-

<PAGE>



          Warrants and Unit Purchase Option and to the best of such counsel's
          knowledge, neither the filing of the Registration Statement nor the
          offering or sale of the Units as contemplated by this Agreement gives
          rise to any registration rights or other rights, other than those
          which have been waived or satisfied for or relating to the
          registration of any shares of Common Stock;

               (iv) this Agreement, the Unit Purchase Option, the Warrant
          Agreement, the Escrow Agreement and the Merger and Acquisition
          Agreement have been duly and validly authorized, executed and
          delivered by IAT and, assuming due execution by each other party
          hereto or thereto, each constitutes a legal, valid and binding
          obligation of IAT enforceable against IAT in accordance with its
          respective terms (except as such enforceability may be limited by
          applicable bankruptcy, insolvency, reorganization, moratorium or other
          laws of general application relating to or affecting enforcement of
          creditors' rights and the application of equitable principles in any
          action, legal or equitable, and except as rights to indemnity or
          contribution may be limited by applicable law);

               (v) the certificates evidencing the shares of Common Stock are in
          valid and proper legal form; the Warrants will be exercisable for
          shares of Common Stock of IAT in accordance with the terms of the
          Warrants and at the prices therein provided for; at all times during
          the term of the Warrants the shares of Common Stock of IAT issuable
          upon exercise of the Warrants have been duly authorized and reserved
          for issuance upon such exercise and such shares, when issued upon such
          exercise in accordance with the terms of the Warrants and at the price
          provided for, will be duly and validly issued, fully paid an
          non-assessable;

               (vi) such counsel knows of no pending or threatened legal or
          governmental proceedings to which either IAT or any of the
          Subsidiaries is a party which could materially adversely affect the
          business, property, financial condition or operations of either IAT or
          any of the Subsidiaries; or which question the validity of the
          Securities, this Agreement, the Warrant Agreement, the Unit Purchase
          Option, the Escrow Agreement or the Merger and Acquisition Agreement,
          or of any action taken or to be taken by either IAT or any of the
          Subsidiaries pursuant to this Agreement, the Warrant Agreement, the
          Unit Purchase Option, the Escrow Agreement or the Merger and
          Acquisition Agreement; and no such proceedings are known to such
          counsel to be contemplated against either IAT or any of the
          Subsidiaries; there are no governmental proceedings or regulations
          required to be described or referred to in the Registration Statement
          which are not so described or referred to;

               (vii) To our knowledge, neither IAT nor any of the Subsidiaries
          has received notice of any claim or challenge regarding its ownership
          of or its other rights to or under any patents, trademarks, service
          marks, trade names, licenses, inventions or any other rights described
          in the Prospectus. To our knowledge (i) no claim has been made against
          IAT or any of the Subsidiaries alleging infringement by IAT or any of
          the Subsidiaries of any patent, trademark, service mark, trade name,
          trade secret, license in or other intellectual property or franchise
          right of any person, (ii) no legal or governmental proceedings are
          pending relating to the foregoing, other than review of pending patent
          applications, and (iii) no such proceedings are currently threatened
          by governmental authorities or others;


                                      -18-

               (viii) Neither IAT nor any of the Subsidiaries is in violation of
          or default under, nor will the execution and delivery of this
          Agreement, the Unit Purchase Option, the Warrant Agreement, the Escrow
          Agreement or the Merger and Acquisition Agreement, and the incurrence
          of the obligations herein and therein set forth and the consummation
          of the transactions herein or therein contemplated, result in a breach
          or violation of, or constitute a default under the certificate or
          articles of incorporation or by-laws (or other organizational
          documents), in the performance or observance of any material
          obligations, agreement, covenant or condition contained in any bond,
          debenture, note or other evidence of indebtedness or in any contract,
          indenture, mortgage, loan agreement, lease, joint venture or other
          agreement or instrument to which IAT or any of the Subsidiaries is a
          party or by which IAT's or any of the Subsidiaries' properties may be
          bound or in violation of any material order, rule, regulation, writ,
          injunction, or decree of any government, governmental instrumentality
          or court, domestic or foreign;

               (ix) the Registration Statement has become effective under the
          Act, and to the best of such counsel's knowledge, no stop order
          suspending the effectiveness of the Registration Statement is in
          effect, and no proceedings for that purpose have been instituted or
          are pending before, or threatened by, the Commission; the Registration
          Statement and the Prospectus (except for the financial statements and
          other financial data contained therein, or omitted therefrom, as to
          which such counsel need express no opinion) comply as to form in all
          material respects with the applicable requirements of the Act and the
          Rules and Regulations;

               (x) such counsel has participated in the preparation of the
          Registration Statement and the Prospectus and nothing has come to the
          attention of such counsel to cause such counsel to have reason to
          believe that the Registration Statement or any amendment thereto at
          the time it became effective or as of the Closing Dates contained any
          untrue statement of a material fact required to be stated therein or
          omitted to state any material fact required to be stated therein or
          necessary to make the statements therein not misleading or that the
          Prospectus or any supplement thereto contains any untrue statement of
          a material fact or omits to state a material fact necessary in order
          to make statements therein, in light of the circumstances under which
          they were made, not misleading (except, in the case of both the
          Registration Statement and any amendment thereto and the Prospectus
          and any supplement thereto, for the financial statements, notes
          thereto and other financial information and schedules contained
          therein, as to which such counsel need express no opinion);

               (xi) all descriptions in the Registration Statement and the
          Prospectus, and any amendment or supplement thereto, of contracts and
          other documents are accurate and fairly present the information
          required to be shown, and such counsel is familiar with all contracts
          and other documents referred to in the Registration Statement and the
          Prospectus and any such amendment or supplement or filed as exhibits
          to the Registration Statement, and such counsel does not know of any
          contracts or documents of a character required to be summarized or
          described therein or to be filed as exhibits thereto which are not so
          summarized, described or filed;

               (xii) no authorization, approval, consent, of license of any
          governmental or regulatory authority or agency is necessary in
          connection with the authorization, issuance, transfer, sale or
          delivery of the Units by IAT, in connection with the execution,
          delivery and performance of this Agreement by IAT or any of the
          Subsidiaries or in connection with the taking of any action
          contemplated herein, or the issuance of the Unit Purchase Option or
          the Securities underlying the Unit Purchase Option, other than
          registrations or qualifications of the Units under applicable state or
          foreign securities or Blue Sky laws and registration under the Act;

               (xiii) the statements in the Registration Statement under the
          captions "Business", "Use of Proceeds", "Management", and "Description
          of Securities" have been reviewed by such counsel and insofar as they
          refer to descriptions of agreements, statements of law, descriptions
          of statutes, licenses, rules or regulations or legal conclusions, are
          correct in all material respects;

               (xiv) the Units, the Common Stock and the Warrants have been duly
          authorized for quotation on the Nasdaq National Market; and

               (xv) to such counsel's knowledge, there are no business
          relationships or related-party transactions of the nature described in
          Item 404 of Regulation S-K involving IAT or any of the Subsidiaries
          and any person described in such Item that are required to be
          disclosed in the Prospectus and which have not been so disclosed.

               Such opinions shall also cover such matters incident to the
          transactions contemplated hereby as the Representative or counsel for
          the Underwriters shall reasonably request. In rendering such opinions,
          such counsel may rely upon certificates of any officer of IAT or the
          Subsidiaries or public officials as to matters of fact; and may rely
          as to all matters of law other than in the case of the opinion of
          counsel for IAT, the law of the United States, the State of Delaware
          or of the State of New York and, in the case of the opinion of counsel
          for IAT AG, the laws of Switzerland, and in the case of the opinion of
          counsel for IAT Germany, the laws of Germany, upon opinions of counsel
          satisfactory to you, in which case the opinions shall state that they
          have no reason to believe that you and they are not entitled to so
          rely.

          (c) All corporate proceedings and other legal matters relating to this
     Agreement, the Registration Statement, the Prospectus and other related
     matters shall be satisfactory to or approved by Bachner, Tally, Polevoy &
     Misher LLP, counsel to the several Underwriters, and you shall have
     received from such counsel a signed opinion, dated as of the First Closing
     Date, together with copies thereof for each of the other Underwriters, with
     respect to the validity of the issuance of the Units, the form of the
     Registration Statement and Prospectus (other than the financial statements
     and other financial data contained therein), the execution of this
     Agreement and other related matters as you may reasonably require. IAT and
     each of the Subsidiaries shall have furnished to counsel for the several
     Underwriters such documents as they may reasonably request for the purpose
     of enabling them to render such opinion.



                                      -20-

          (d) You shall have received a letter prior to the effective date of
     the Registration Statement and again on and as of the First Closing Date
     from Rothstein, Kass & Company, P.C., independent public accountants for
     IAT, substantially in the form approved by you, and including estimates of
     IAT's revenues and results of operations for the period ending at the end
     of the month immediately preceding the effective date and results of the
     comparable period during the prior fiscal year.

          (e) At the Closing Dates, (i) the representations and warranties of
     IAT contained in this Agreement shall be true and correct with the same
     effect as if made on and as of the Closing Dates and IAT and each of the
     Subsidiaries shall have performed all of its obligations hereunder and
     satisfied all the conditions on its part to be satisfied at or prior to
     such Closing Date; (ii) the Registration Statement and the Prospectus and
     any amendments or supplements thereto shall contain all statements which
     are required to be stated therein in accordance with the Act and the Rules
     and Regulations, and shall in all material respects conform to the
     requirements thereof, and neither the Registration Statement nor the
     Prospectus nor any amendment or supplement thereto shall contain any untrue
     statement of a material fact or omit to state any material fact required to
     be stated therein or necessary to make the statements therein not
     misleading; (iii) there shall have been, since the respective dates as of
     which information is given, no material adverse change, or any development
     involving a prospective material adverse change, in the business,
     properties, condition (financial or otherwise), results of operations,
     capital stock, long-term or short-term debt or general affairs of IAT or
     any of the Subsidiaries from that set forth in the Registration Statement
     and the Prospectus, except changes which the Registration Statement and
     Prospectus indicate might occur after the effective date of the
     Registration Statement, and IAT and each of the Subsidiaries shall not have
     incurred any material liabilities or entered into any agreement not in the
     ordinary course of business other than as referred to in the Registration
     Statement and Prospectus; and (iv) except as set forth in the Prospectus,
     no action, suit or proceeding at law or in equity shall be pending or
     threatened against IAT or any of the Subsidiaries which would be required
     to be set forth in the Registration Statement, and no proceedings shall be
     pending or threatened against IAT or any of the Subsidiaries before or by
     any commission, board or administrative agency in the United States,
     Switzerland, Germany or elsewhere, wherein an unfavorable decision, ruling
     or finding would materially and adversely affect the business, property,
     condition (financial or otherwise), results of operations or general
     affairs of IAT or any of the Subsidiaries, and (v) you shall have received,
     at the First Closing Date, a certificate signed by each of the Co-Chairman
     of the Board, Chief Executive Officer and President and the principal
     financial or accounting officer of IAT, dated as of the First Closing Date,
     evidencing compliance with the provisions of this subsection (e).

          (f) Upon exercise of the option provided for in Section 2(b) hereof,
     the obligations of the several Underwriters (or, at its option, the
     Representative, individually) to purchase and pay for the Option Units
     referred to therein will be subject (as of the date hereof and as of the
     Option Closing Date) to the following additional conditions:



                                      -21-

<PAGE>



               (i) The Registration Statement shall remain effective at the
          Option Closing Date, and no stop order suspending the effectiveness
          thereof shall have been issued and no proceedings for that purpose
          shall have been instituted or shall be pending, or, to your knowledge
          or the knowledge of IAT, shall be contemplated by the Commission, and
          any reasonable request on the part of the Commission for additional
          information shall have been complied with to the satisfaction of
          Bachner, Tally, Polevoy & Misher LLP, counsel to the several
          Underwriters.

               (ii) At the Option Closing Date there shall have been delivered
          to you as Representative the signed opinions of Baker & McKenzie, New
          York, counsel for IAT, Baker & McKenzie, Zurich, counsel for IAT AG
          and Dr. Schackow & Partners, Bremen, foreign counsel for the
          Subsidiaries, dated as of the Option Closing Date, in form and
          substance satisfactory to Bachner, Tally, Polevoy & Misher LLP,
          counsel to the several Underwriters, together with copies of such
          opinions for each of the other several underwriters, which opinions
          shall be substantially the same in scope and substance as the opinions
          furnished to you at the First Closing Date pursuant to Section 4(b)
          hereof, except that such opinions, where appropriate, shall cover the
          Option Units.

               (iii) At the Option Closing Date there shall have been delivered
          to you a letter in form and substance satisfactory to you from
          Rothstein, Kass & Company, P.C., dated the Option Closing Date and
          addressed to the Underwriters confirming the information in their
          letter referred to in Section 4(d) hereof and stating that nothing has
          come to their attention during the period from the ending date of
          their review referred to in said letter to a date not more than five
          business days prior to the Option Closing Date, which would require
          any change in said letter if it were required to be dated the Option
          Closing Date.

               (iv) At the Option Closing Date there shall have been delivered
          to you a certificate of the Co-Chairman of the Board, Chief Executive
          Officer and President and the principal financial or accounting
          officer of IAT, dated the Option Closing Date, in form and substance
          satisfactory to Bachner, Tally, Polevoy & Misher LLP, counsel to the
          several Underwriters, substantially the same in scope and substance as
          the certificate furnished to you at the First Closing Date pursuant to
          Section 4(e) hereof.

               (v) All proceedings taken at or prior to the Option Closing Date
          in connection with the sale and issuance of the Option Units shall be
          satisfactory in form and substance to you, and you and Bachner, Tally,
          Polevoy & Misher LLP, counsel to the several Underwriters, shall have
          been furnished with all such documents, certificates, and opinions as
          you may request in connection with this transaction in order to
          evidence the accuracy and completeness of any of the representations,
          warranties or statements of IAT and each of the Subsidiaries or its
          compliance with any of the covenants or conditions contained herein.

          (g) No action shall have been taken by the Commission or the NASD the
     effect of which would make it improper, at any time prior to the Closing
     Date, for members of the NASD to execute transactions (as principal or
     agent) in the Units, Common Stock or the


                                      -22-

<PAGE>



     Warrants and no proceedings for the taking of such action shall have been
     instituted or shall be pending, or, to the knowledge of the Representative
     or IAT, shall be contemplated by the Commission or the NASD. IAT represents
     that at the date hereof it has no knowledge that any such action is in fact
     contemplated by the Commission or the NASD. IAT and each of the
     Subsidiaries shall have advised the Underwriters of any NASD affiliation of
     any of its officers, directors, stockholders or their affiliates.

          (h) If any of the conditions herein provided for in this Section shall
     not have been fulfilled as of the date indicated, this Agreement and all
     obligations of the several Underwriters under this Agreement may be
     cancelled at, or at any time prior to, each Closing Date by the
     Representative. Any such cancellation shall be without liability of the
     Underwriters to IAT.

     5. Conditions of the Obligations of IAT. The obligation of IAT to sell and
deliver the Units is subject to the condition that at the Closing Dates, no stop
orders suspending the effectiveness of the Registration Statement shall have
been issued under the Act or any proceedings therefor initiated or threatened by
the Commission.

     If the condition to the obligations of IAT provided for in this Section
have been fulfilled on the First Closing Date but are not fulfilled after the
First Closing Date and prior to the Option Closing Date, then only the
obligation of IAT to sell and deliver the Units on exercise of the option
provided for in Section 2(b) hereof shall be affected.

     6. Indemnification.

          (a) IAT agrees to indemnify and hold harmless each Underwriter and
     each person, if any, who controls any Underwriter within the meaning of the
     Act against any losses, claims, damages or liabilities, joint or several
     (which shall, for all purposes of this Agreement, include, but not be
     limited to, all reasonable costs of defense and investigation and all
     attorneys' fees), to which such Underwriter or such controlling person may
     become subject, under the Act or otherwise, and will reimburse, as
     incurred, such Underwriters and such controlling persons for any legal or
     other expenses reasonably incurred in connection with investigating,
     defending against or appearing as a third party witness in connection with
     any losses, claims, damages or liabilities, insofar as such losses, claims,
     damages or liabilities (or actions in respect thereof) arise out of or are
     based upon any untrue statement or alleged untrue statement of any material
     fact contained in (A) the Registration Statement, any Preliminary
     Prospectus, the Prospectus, or any amendment or supplement thereto, (B) any
     blue sky application or other document executed by the Company or any of
     the Subsidiaries specifically for that purpose or based upon written
     information furnished by the Company or any Subsidiaries filed in any state
     or other jurisdiction in order to qualify any or all of the Units under the
     securities laws thereof (any such application, document or information
     being hereinafter called a "Blue Sky Application"), or arise out of or are
     based upon the omission or alleged omission to state in the Registration
     Statement, any Preliminary Prospectus, Prospectus, or any amendment or
     supplement thereto, or in any Blue Sky Application, a material fact


                                      -23-

<PAGE>



     required to be stated therein or necessary to make the statements therein
     not misleading; provided, however, that IAT will not be liable in any such
     case to the extent, but only to the extent, that any such loss, claim,
     damage or liability arises out of or is based upon an untrue statement or
     alleged untrue statement or omission or alleged omission made in reliance
     upon and in conformity with written information furnished to the Company or
     any Subsidiaries by or on behalf of the Underwriters specifically for use
     in the preparation of the Registration Statement or any such amendment or
     supplement thereof or any such Blue Sky Application or any such preliminary
     Prospectus or the Prospectus or any such amendment or supplement thereto.
     This indemnity will be in addition to any liability which IAT may otherwise
     have.

          (b) Each Underwriter severally, but not jointly, will indemnify and
     hold harmless IAT, each of its directors, each nominee (if any) for
     director named in the Prospectus, each of its officers who have signed the
     Registration Statement, and each person, if any, who controls IAT within
     the meaning of the Act, against any losses, claims, damages or liabilities
     (which shall, for all purposes of this Agreement, include, but not be
     limited to, all costs of defense and investigation and all attorneys' fees)
     to which IAT or any such director, nominee, officer or controlling person
     may become subject under the Act or otherwise, insofar as such losses,
     claims, damages or liabilities (or actions in respect thereof) arise out of
     or are based upon any untrue statement or alleged untrue statement of any
     material fact contained in the Registration Statement, any Preliminary
     Prospectus, the Prospectus, or any amendment or supplement thereto, or
     arise out of or are based upon the omission or the alleged omission to
     state therein a material fact required to be stated therein or necessary to
     make the statements therein not misleading, in each case to the extent, but
     only to the extent, that such untrue statement or alleged untrue statement
     or omission or alleged omission was made in the Registration Statement, any
     Preliminary Prospectus, the Prospectus, or any amendment or supplement
     thereto (i) in reliance upon and in conformity with written information
     furnished to IAT by you or by any Underwriter through you specifically for
     use in the preparation thereof and (ii) relates to the transactions
     effected by the Underwriters in connection with the offer and sale of the
     Units contemplated hereby. This indemnity agreement will be in addition to
     any liability which the Underwriters may otherwise have.

          (c) Promptly after receipt by an indemnified party under this Section
     of notice of the commencement of any action, such indemnified party will,
     if a claim in respect thereof is to be made against the indemnifying party
     under this Section, notify in writing the indemnifying party of the
     commencement thereof; but the omission so to notify the indemnifying party
     will not relieve it from any liability which it may have to any indemnified
     party otherwise than under this Section. In case any such action is brought
     against any indemnified party, and it notifies the indemnifying party of
     the commencement thereof, the indemnifying party will be entitled to
     participate in, and, to the extent that it may wish, jointly with any other
     indemnifying party similarly notified, to assume the defense thereof,
     subject to the provisions herein stated, with counsel reasonably
     satisfactory to such indemnified party, and after notice from the
     indemnifying party to such indemnified party of its election so to assume
     the defense thereof, the indemnifying party will not be liable to such
     indemnified party under this Section for any legal or other expenses
     subsequently incurred by such indemnified party in connection with the


                                      -24-

<PAGE>



     defense thereof other than reasonable costs of investigation. The
     indemnified party shall have the right to employ separate counsel in any
     such action and to participate in the defense thereof, but the fees and
     expenses of such counsel shall not be at the expense of the indemnifying
     party if the indemnifying party has assumed the defense of the action with
     counsel reasonably satisfactory to the indemnified party; provided that if
     the indemnified party is an Underwriter or a person who controls such
     Underwriter within the meaning of the Act, the fees and expenses of such
     counsel shall be at the expense of the indemnifying party if (i) the
     employment of such counsel has been specifically authorized in writing by
     the indemnifying party or (ii) the named parties to any such action
     (including any impleaded parties) include both such Underwriter or such
     controlling person and the indemnifying party and in the judgment of the
     Representative, it is advisable for the Representative or such Underwriters
     or controlling persons to be represented by separate counsel (in which case
     the indemnifying party shall not have the right to assume the defense of
     such action on behalf of such Underwriter or such controlling person, it
     being understood, however, that the indemnifying party shall not, in
     connection with any one such action or separate but substantially similar
     or related actions in the same jurisdiction arising out of the same general
     allegations or circumstances, be liable for the reasonable fees and
     expenses of more than one separate firm of attorneys for all such
     Underwriters and controlling persons, which firm shall be designated in
     writing by you). No settlement of any action against an indemnified party
     shall be made without the consent of the indemnifying party, which shall
     not be unreasonably withheld in light of all factors of importance to such
     indemnifying party.

     7. Contribution.

     In order to provide for just and equitable contribution under the Act in
any case in which (i) any Underwriter makes claim for indemnification pursuant
to Section 6 hereof but it is judicially determined (by the entry of a final
judgment or decree by a court of competent jurisdiction and the expiration of
time to appeal or the denial of the last right of appeal) that such
indemnification may not be enforced in such case, notwithstanding the fact that
the express provisions of Section 6 provide for indemnification in such case, or
(ii) contribution under the Act may be required on the part of any Underwriter,
then IAT and each person who controls IAT, in the aggregate, and any such
Underwriter shall contribute to the aggregate losses, claims, damages or
liabilities to which they may be subject (which shall, for all purposes of this
Agreement, include, but not be limited to, all reasonable costs of defense and
investigation and all reasonable attorneys' fees) in either such case (after
contribution from others) in such proportions that all such Underwriters are
responsible in the aggregate for that portion of such losses, claims, damages or
liabilities represented by the percentage that the underwriting discount per
Unit appearing on the cover page of the Prospectus bears to the public offering
price appearing thereon, and IAT shall be responsible for the remaining portion,
provided, however, that (a) if such allocation is not permitted by applicable
law then the relative fault of IAT and the Underwriters and controlling persons,
in the aggregate, in connection with the statements or omissions which resulted
in such damages and other relevant equitable considerations shall also be
considered. The relative fault shall be determined by reference to, among other
things, whether in the case of an untrue statement of a material fact or the
omission to state a material fact, such statement or omission relates to
information supplied by the Company or any of the


                                      -25-

<PAGE>



Subsidiaries, or the Underwriters and the parties' relative intent, knowledge,
access to information and opportunity to correct or prevent such untrue
statement or omission. IAT and the Underwriters agree that it would not be just
and equitable if the respective obligations of IAT and the Underwriters to
contribute pursuant to this Section 7 were to be determined by pro rata or per
capita allocation of the aggregate damages (even if the Underwriters in the
aggregate were treated as one entity for such purpose) or by any other method of
allocation that does not take account of the equitable considerations referred
to in the first sentence of this Section 7 and (b) that the contribution of each
contributing Underwriter shall not be in excess of its proportionate share
(based on the ratio of the number of Units purchased by such Underwriter to the
number of Units purchased by all contributing Underwriters) of the portion of
such losses, claims, damages or liabilities for which the Underwriters are
responsible. No person guilty of a fraudulent misrepresentation (within the
meaning of Section 11(f) of the Act) shall be entitled to contribution from any
person who is not guilty of such fraudulent misrepresentation. As used in this
paragraph, the word "Company" includes any officer, director, or person who
controls IAT within the meaning of Section 15 of the Act. If the full amount of
the contribution specified in this paragraph is not permitted by law, then any
Underwriter and each person who controls any Underwriter shall be entitled to
contribution from IAT, its officers, directors and controlling persons to the
full extent permitted by law. The foregoing contribution agreement shall in no
way affect the contribution liabilities of any persons having liability under
Section 11 of the Act other than IAT and the Underwriters. No contribution shall
be requested with regard to the settlement of any matter from any party who did
not consent to the settlement; provided, however, that such consent shall not be
unreasonably withheld in light of all factors of importance to such party.

     8. Costs and Expenses.

          (a) Whether or not this Agreement becomes effective or the sale of the
     Units to the Underwriters is consummated, IAT will pay all costs and
     expenses incident to the performance of this Agreement by the Company
     including, but not limited to, the fees and expenses of counsel to the
     Company and of the Company 's accountants; the costs and expenses incident
     to the preparation, printing, filing and distribution under the Act of the
     Registration Statement (including the financial statements therein and all
     amendments and exhibits thereto), Preliminary Prospectus and the
     Prospectus, as amended or supplemented, or the Term Sheet, the fee of the

     Underwriters' obligations hereunder required to be fulfilled by the Company
     or any of the Subsidiaries is not fulfilled) IAT shall be liable for only
     the amount (not less than $50,000) paid by the Company to the
     Representation prior to such determination. In the event the transactions
     contemplated hereby are not consummated by reason of any action of the
     Company or any Subsidiary or because of a breach by the Company or any
     Subsidiary of any covenant, representation or warranty herein, IAT shall be

     compensation from the Company, from the Representative or from any other
     person for services as a finder in connection with the proposed offering,
     and IAT agrees to indemnify and hold harmless the Representative and the
     other Underwriters, against any losses, claims, damages or liabilities,
     joint or several (which shall, for all purposes of this Agreement, include,
     but not be limited to, all costs of defense and investigation and all
     attorneys' fees), to which the Representative or such other Underwriter or
     person may become subject insofar as such losses, claims, damages or
     liabilities (or actions in respect thereof) arise out of or are based upon
     the claim of any person (other than an employee of the party claiming
     indemnity) or entity that he or it is entitled to a finder's fee in
     connection with the proposed offering by reason of such person's or
     entity's influence or prior contact with the indemnifying party.

     9. Substitution of Underwriters.

     If any Underwriters shall for any reason not permitted hereunder cancel
their obligations to purchase the First Units hereunder, or shall fail to take
up and pay for the number of First Units set forth opposite their respective
names in Schedule A hereto upon tender of such First Units in accordance with
the terms hereof, then:


                                      -27-

<PAGE>



          (a) If the aggregate number of First Units which such Underwriter or
     Underwriters agreed but failed to purchase does not exceed 10% of the total
     number of First Units, the other Underwriters shall be obligated severally,
     in proportion to their respective commitments hereunder, to purchase the
     First Units which such defaulting Underwriter or Underwriters agreed but
     failed to purchase.

          (b) If any Underwriter or Underwriters so default and the agreed
     number of First Units with respect to which such default or defaults occurs
     is more than 10% of the total number of First Units, the remaining
     Underwriters shall have the right to take up and pay for (in such
     proportion as may be agreed upon among them) the First Units which the
     defaulting Underwriter or Underwriters agreed but failed to purchase. If
     such remaining Underwriters do not, at the First Closing Date, take up and
     pay for the First Units which the defaulting Underwriter or Underwriters
     agreed but failed to purchase, the time for delivery of the First Units
     shall be extended to the next business day to allow the several
     Underwriters the privilege of substituting within twenty-four hours
     (including nonbusiness hours) another underwriter or underwriters
     satisfactory to IAT. If no such underwriter or underwriters shall have been
     substituted as aforesaid, within such twenty-four hour period, the time of
     delivery of the First Units may, at the option of IAT, be again extended to
     the next following business day, if necessary, to allow IAT the privilege
     of finding within twenty-four hours (including nonbusiness hours) another
     underwriter or underwriters to purchase the First Units which the
     defaulting Underwriter or Underwriters agreed but failed to purchase. If it
     shall be arranged for the remaining Underwriters or substituted
     Underwriters to take up the First Units of the defaulting Underwriter or
     Underwriters as provided in this Section, (i) IAT or the Representative
     shall have the right to postpone the time of delivery for a period of not
     more than seven business days, in order to effect whatever changes may
     thereby be made necessary in the Registration Statement or the Prospectus,
     or in any other documents or arrangements, and IAT agrees promptly to file
     any amendments to the Registration Statement or supplements to the
     Prospectus which may thereby be made necessary, and (ii) the respective
     numbers of First Units to be purchased by the remaining Underwriters or
     substituted Underwriters shall be taken at the basis of the underwriting
     obligation for all purposes of this Agreement.

          If in the event of a default by one or more Underwriters and the
     remaining Underwriters shall not take up and pay for all the First Units
     agreed to be purchased by the defaulting Underwriters or substitute another
     underwriter or underwriters as aforesaid, IAT shall not find or shall not
     elect to seek another underwriter or underwriters for such First Units as
     aforesaid, then this Agreement shall terminate.

          If, following exercise of the option provided in Section 2(b) hereof,
     any Underwriter or Underwriters shall for any reason not permitted
     hereunder cancel their obligations to purchase Option Units at the Option
     Closing Date, or shall fail to take up and pay for the number of Option
     Units, which they become obligated to purchase at the Option Closing Date
     upon tender of such Option Units in accordance with the terms hereof, then
     the remaining Underwriters or substituted Underwriters may take up and pay
     for the Option Units of the defaulting Underwriters in the manner provided
     in Section 9(b) hereof. If the remaining


                                      -28-

<PAGE>



     Underwriters or substituted Underwriters shall not take up and pay for all
     such Option Units, the Underwriters shall be entitled to purchase the
     number of Option Units for which there is no default or, at their election,
     the option shall terminate, the exercise thereof shall be of no effect.

          As used in this Agreement, the term "Underwriter" includes any person
     substituted for an Underwriter under this Section. In the event of
     termination, there shall be no liability on the part of any nondefaulting
     Underwriter to IAT, provided that the provisions of this Section 9 shall
     not in any event affect the liability of any defaulting Underwriter to IAT
     arising out of such default.

     10. Effective Date.

     The Agreement shall become effective upon its execution except that you
may, at your option, delay its effectiveness until 11:00 A.M., New York time on
the first full business day following the effective date of the Registration
Statement, or at such earlier time after the effective date of the Registration
Statement as you in your discretion shall first commence the initial public
offering by the Underwriters of any of the Units. The time of the initial public
offering shall mean the time of release by you of the first newspaper
advertisement with respect to the Units, or the time when the Units are first
generally offered by you to dealers by letter or telegram, whichever shall first
occur. This Agreement may be terminated by you at any time before it becomes
effective as provided above, except that Sections 3(c), 6, 7, 8, 13, 14, 15 and
16 shall remain in effect notwithstanding such termination.

     16 hereof, may be terminated at any time prior to the First Closing Date,
     and the option referred to in Section 2(b) hereof, if exercised, may be
     cancelled at any time prior to the Option Closing Date, by you if in your
     judgment it is impracticable to offer for sale or to enforce contracts made
     by the Underwriters for the resale of the Units agreed to be purchased
     hereunder by reason of (i) the Company or any of the Subsidiaries having
     sustained a material loss, whether or not insured, by reason of fire,
     earthquake, flood, accident or other calamity, or from any labor dispute or
     court or government action, order or decree; (ii) trading in securities on
     the New York Stock Exchange, the American Stock Exchange, the Nasdaq
     SmallCap Market or the Nasdaq National Market having been suspended or
     limited; (iii) material governmental restrictions having been imposed on
     trading in securities generally (not in force and effect on the date
     hereof); (iv) a banking moratorium having been declared by federal or New
     York state authorities; (v) an outbreak of international hostilities or
     other national or international calamity or crisis or change in economic or
     political conditions having occurred; (vi) a pending or threatened legal or
     governmental proceeding or action relating generally to IAT's or any of the
     Subsidiaries' business, or a notification having been received by either
     IAT or any of the Subsidiaries of the threat of any such proceeding or
     action, which could materially adversely affect IAT or any of the
     Subsidiaries; (vii) except as contemplated by the Prospectus, IAT or any of
     the Subsidiaries is merged or consolidated into or acquired by another
     company or group or there exists a binding


                                      -29-

<PAGE>



     legal commitment for the foregoing or any other material change of
     ownership or control occurs; (viii) the passage by the Congress of the
     United States or by any state legislative body or federal or state agency
     or other authority of any act, rule or regulation, measure, or the adoption
     of any orders, rules or regulations by any governmental body or any
     authoritative accounting institute or board, or any governmental executive,
     which is reasonably believed likely by the Representative to have a
     material impact on the business, financial condition or financial
     statements of the Company or the market for the securities offered pursuant
     to the Prospectus; (ix) any adverse change in the financial or securities
     markets beyond normal market fluctuations having occurred since the date of
     this Agreement, or (x) any material adverse change having occurred, since
     the respective dates of which information is given in the Registration
     Statement and Prospectus, in the earnings, business prospects or general
     condition of IAT or any of its Subsidiaries, financial or otherwise,
     whether or not arising in the ordinary course of business.

          (b) If you elect to prevent this Agreement from becoming effective or
     to terminate this Agreement as provided in this Section 11 or in Section
     10, IAT shall be promptly notified by you, by telephone or telegram,
     confirmed by letter.

     12. Unit Purchase Option.

     At or before the First Closing Date, IAT will sell to the Underwriters, or
their designees for a consideration of $310, and upon the terms and conditions
set forth in the form of Unit Purchase Option annexed as an exhibit to the
Registration Statement, a Unit Purchase Option to purchase an aggregate of
310,000 Units. In the event of conflict in the terms of this Agreement and the
Unit Purchase Option, the language of the Unit Purchase Option shall control.

     13. Representations, Warranties and Agreements to Survive Delivery.

     The respective indemnities, agreements, representations, warranties and
other statements of IAT or its Principal Stockholders, where appropriate, and
the undertakings set forth in or made pursuant to this Agreement will remain in
full force and effect, regardless of any investigation made by or on behalf of
the Underwriters, IAT or any of its officers or directors or any controlling
person and will survive delivery of and payment of the Units and the termination
of this Agreement.

splits, combinations or similar events) during the one year period following the

any such annual anniversary, all accrued dividends shall be paid on a
proportionate basis through the date of such conversion or retirement.

     (b) Subject to the rights of any series of preferred stock of the
Corporation the terms of which specifically provide that such series ranks
senior to the Series A Preferred Stock, or the terms of which specifically
provide that such series ranks pari passu with the Series A Preferred Stock, the
holders of shares of Series A Preferred Stock shall be entitled to receive
dividends, out of any assets legally available therefor, prior and in preference
to any declaration or payment of any dividend (payable other than in Common
Stock of the Corporation (the "Common Stock") or other securities and rights
convertible into or entitling the holder thereof to receive, directly or
indirectly, additional shares of Common Stock) on the Common Stock or other
junior securities of the Corporation, when, as and if declared by the Board of
Directors. No dividends shall be payable upon any junior or pari passu
securities of the Corporation unless equivalent dividends, on an as-converted
basis, are declared and paid concurrently on the Series A Preferred Stock.

     B. Liquidation Preference. (a) In the event of any liquidation, dissolution
or winding up of the Corporation, either voluntary or involuntary (a
"Liquidation"), the holders of shares of Series A Preferred Stock shall be
entitled to receive, prior and in preference to any distribution of any of the
assets of the Corporation to the holders of any Junior Securities (as defined
below) by reason of their ownership thereof, an amount per share equal to $0.80
(as adjusted for stock splits, combinations or similar events) for each
outstanding share of Series A Preferred Stock plus any accrued or declared but
unpaid dividends (the "Series A Liquidation Preference"). If, upon the
occurrence of such an event, the assets and funds thus distributed among the
holders of the Series A Preferred Stock shall be insufficient to permit the
payment to such holders of the full aforesaid preferential amounts, then the
entire assets and funds of the Corporation legally available for distribution
shall be distributed ratably among the holders of the Series A Preferred Stock
such that an equal amount shall be paid with respect to each outstanding share
of Series A Preferred Stock. For purposes of this subsection (a), a "Junior
Security" shall include (i) the Common Stock and (ii) any series of preferred
stock the terms of which provide that such series ranks junior and subordinate
to the Series A Preferred Stock with respect to the distribution of assets upon
any Liquidation or deemed liquidation.


                                        4

     (b) For purposes of this Section 2, a Liquidation shall be deemed to be
occasioned by, or to include, (i) the acquisition of the Corporation by another
entity by means of any transaction or series of related transactions (including,
without limitation, any reorganization, merger or consolidation, but excluding
any merger effected exclusively for the purpose of changing the domicile of the
Corporation); or (ii) a sale of all or substantially all of the assets of the
Corporation; unless the Corporation's stockholders of record as constituted
immediately prior to such acquisition or sale will, immediately after such
acquisition or sale (by virtue of securities issued as consideration for the
Corporation's acquisition or sale or otherwise) hold at least 51% of the voting
power of the surviving or acquiring entity.

     C. Redemption.

     (a) Optional Redemption by Holders of Series A Preferred Stock.

     (i) At the written request of the holders of any then outstanding shares of
Series A Preferred Stock, mailed to the Corporation at any time following the
second annual anniversary of the Purchase Date, the Corporation shall, to the
extent it may do so under applicable law, redeem from such holders of Series A
Preferred Stock all shares of Series A Preferred Stock requested to be redeemed
on the date (the "Redemption Date") that is sixty (60) days following the date
of the request. In the event shares of Series A Preferred Stock scheduled for
redemption are not redeemed because of a prohibition under applicable law, such
shares shall be redeemed as soon as such prohibition no longer exists.

     (ii) The redemption price (the "Redemption Price") for each share of Series
A Preferred Stock redeemed pursuant to this Section 3(a) shall be equal to the
Series A Liquidation Preference. In the event that the holders of the Series A
Preferred Stock do not elect to have the Series A Preferred Stock redeemed
pursuant to this Section 3(a), the shares of Series A Preferred Stock shall
remain outstanding and subject to the rights and preferences contained herein.

     (iii) Nothing contained in this Section 3(a) shall in any way restrict or
prohibit the holders of Series A Preferred Stock from exercising their
conversion rights pursuant to Section 4 hereof prior to the effective date of
the redemption to be effected hereunder.

     (b) Company Redemption. If, at any time after December 31, 1997, the
Company has not consummated an IPO, the Company may redeem all, but not less
than all, of the outstanding shares of Series A Preferred Stock on the date (the
"Redemption Date") that is sixty (60) days following the date of the written
request at a redemption price per share equal to the Series A Liquidation
Preference.

     (c) Redemption Notice. If an election is made by any holder of Series A
Preferred Stock pursuant to Section 3(a)(i) hereof or by the Company pursuant to
Section 3(b) hereof, then, at least forty-five (45) days before the Redemption
Date, written notice (hereinafter referred to as the "Redemption Notice") shall
be mailed by the Corporation, postage prepaid, to each holder of record


                                        5

<PAGE>



of  Series  A  Preferred  Stock  at its  address  shown  on the  records  of the
Corporation;  provided,  however,  that the  Corporation's  failure to give such
Redemption  Notice shall in no way affect its obligation to redeem the shares of
Series A Preferred Stock as provided in Section 3(a)(i) hereof.
The Redemption Notice shall contain the following information:

          (i) the number of shares of Series A Preferred Stock held by the
     holder and the total number of shares of Series A Preferred Stock held by
     all holders subject to redemption as of such Redemption Date; and

          (ii) the Redemption Date and the applicable Redemption Price.

     Any holder of Series A Preferred Stock who wishes to do so may, by giving
notice to the Corporation prior to the Redemption Date, convert into common
stock any or all of the shares of Series A Preferred Stock held by him and
scheduled for redemption on such Redemption Date.

     (d) Surrender of Certificates. Each holder of shares of Series A Preferred
Stock to be redeemed under this Section 3 shall surrender the certificate or
certificates representing such shares to the Corporation at the place designated
in the Redemption Notice, and thereupon the Redemption Price for such shares as
set forth in this Section 3 shall be paid to the order of the person whose name
appears on such certificate or certificates. Irrespective of whether the
certificates therefore shall have been surrendered, all shares of Series A
Preferred Stock which are the subject of a Redemption Notice shall be deemed to
have been redeemed and shall be canceled effective as of the Redemption Date,
unless the Corporation shall default in the payment of the applicable Redemption
Price.

     (e) Financing Requirement. To the extent that the Corporation does not have
funds legally available to fund any required redemption of shares of Series A
Preferred Stock, the Corporation shall use its commercially reasonable best
efforts to raise sufficient capital to fund such required redemption within
sixty (60) days of the date such redemption is required to be made. To the
extent that the Corporation is unable to raise sufficient capital to fund such
required redemption within such sixty (60) day period, the Corporation shall
commence, as of the sixty-first (61st) day following the date such redemption is
required to be made, a rights offering of the Corporation's common stock to all
of the Corporation's shareholders of an adequate number of shares at a purchase
price per share equal to its then fair market value such that the total dollar
amount to be raised from such rights offering will equal or exceed the dollar
amount needed by the Corporation to fund such required redemption; provided,
however, that notwithstanding anything contained in this Section 3 to the
contrary, no stockholder of the Corporation will be required to subscribe for
the common stock offered pursuant to the contemplated rights offering.

     4. Conversion. The holders of the Series A Preferred Stock shall have
conversion rights as follows (the "Conversion Rights"):




                                        6

<PAGE>



          (a) Right to Convert. Each share of Series A Preferred Stock shall be
     convertible, at the option of the holder thereof at any time after the date
     of issuance of such share at the office of the Corporation or any transfer
     agent for such stock. Each share of Series A Preferred Stock shall be
     convertible into the number of fully paid and nonassessable shares of
     Common Stock equal to a fraction, the numerator of which is the "Conversion
     Value" per share of such Series A Preferred Stock and the denominator of
     which is the "Conversion Price" per share in effect for such Series A
     Preferred Stock at the time of conversion. The number of shares of Common
     Stock into which each share of Series A Preferred Stock is convertible is
     hereinafter collectively referred to as the "Conversion Rate" for such
     series. The Conversion Price of each of the Series A Preferred Stock shall
     be subject to adjustment as set forth in subsection 4(d). The initial
     Conversion Price per share of Series A Preferred Stock shall be $0.80,
     subject to adjustment for stock splits, combinations or similar events
     affecting the Series A Preferred Stock. The Conversion Value per share of
     Series A Preferred Stock shall be $0.80.

          (b) Automatic Conversion. Each share of Series A Preferred Stock shall
     automatically be converted into shares of Common Stock at the then
     effective Conversion Rate for such series immediately upon the closing of
     the Corporation's sale of its Common Stock in a firm commitment
     underwritten public offering pursuant to a registration statement on Form
     S-1 or F-1 (or any equivalent successor form) under the Securities Act of
     1933, as amended. In addition each share of any series of Series A
     Preferred Stock shall automatically be so converted on the date specified
     by written consent or agreement of the holders of sixty-six and two-thirds
     percent (66 2/3%) of the then outstanding shares of such series of Series A
     Preferred Stock

          (c) Mechanics of Conversion. Before any holder of Series A Preferred
     Stock shall be entitled to convert the same into shares of Common Stock,
     such holder shall surrender the certificate or certificates therefor, duly
     endorsed, at the office of the Corporation or of any transfer agent for the
     Series A Preferred Stock, and shall give written notice to the Corporation
     at its principal corporate office, of the election to convert the same and
     shall state therein the name or names in which the certificate or
     certificates for shares of Common Stock are to be issued. The Corporation
     shall, as soon as practicable thereafter, issue and deliver at such office
     to such holder of Series A Preferred Stock, or to the nominee or nominees
     of such holder, a certificate or certificates for the number of shares of
     Common Stock to which such holder shall be entitled as aforesaid. Such
     conversion shall be deemed to have been made immediately prior to the close
     of business on the date of such surrender of the shares of Series A
     Preferred Stock to be converted, and the person or persons entitled to
     receive the shares of Common Stock issuable upon such conversion shall be
     treated for all purposes as the record holder or holders of such shares of
     Common Stock as of such date. If the conversion is in connection with an
     underwritten offering of securities registered pursuant to the Securities
     Act of 1933, as amended, the conversion may, at the option of any holder
     tendering Series A Preferred Stock for conversion, be conditioned upon the
     closing with the underwriters of the sale of securities pursuant to such
     offering, in which event the person(s) entitled to receive the Common Stock
     upon conversion of the Series A Preferred Stock shall not be deemed to have
     converted such Series A Preferred Stock until immediately prior to the
     closing of such sale of securities.


                                        7

          (d) Conversion Price Adjustments of Series A Preferred Stock. The
     Conversion Price of the Series A Preferred Stock shall be subject to
     adjustment from time to time as set forth below.

               (i) (A) If the Corporation shall issue, after the Purchase Date,
          any Additional Stock (as defined below) at a purchase price less than
          or equal to $5.16 (as adjusted for stock splits, combinations or
          similar events), the Conversion Price for the Series A Preferred
          Stock, in effect immediately prior to each such issuance shall
          automatically (except as otherwise provided in this clause (i)) be
          adjusted to a price determined by multiplying such Conversion Price by
          a fraction, the numerator of which shall be the number of shares of
          Common Stock outstanding immediately prior to such issuance plus the
          number of shares of Common Stock that the aggregate consideration
          received by the Corporation for such issuance would purchase at such
          Conversion Price, and the denominator of which shall be the number of
          shares of Common Stock outstanding immediately prior to such issuance
          plus the number of shares of such Additional Stock.

                    (B) No adjustment in the Conversion Price for the Series A
               Preferred Stock shall be required unless such adjustment would
               require an increase or decrease of at least five cents ($0.05) in
               such price; provided, however, that any adjustments which by
               reason of this subsection (C) are not required to be made shall
               be carried forward and taken into account in any subsequent
               adjustment required to be made hereunder. All calculations under
               this section 4(d)(i) shall be made to the nearest one cent
               ($0.01). Except to the limited extent provided for in subsections
               (E)(3) and (E)(4), no adjustment of such Conversion Price
               pursuant to this subsection 4(d)(i) shall have the effect of
               increasing the Conversion Price above the Conversion Price in
               effect immediately prior to such adjustment.

                    (C) In the case of the issuance (whether before, on or after
               the Purchase Date) of options to purchase or rights to subscribe
               for Common Stock, securities by their terms convertible into or
               exchangeable for Common Stock or options to purchase or rights to
               subscribe for such convertible or exchangeable securities, the
               following provisions shall apply for all purposes of this
               subsection 4(d)(i) and subsection 4(d)(ii):

                         (1) The aggregate maximum number of shares of Common
                    Stock deliverable upon exercise (assuming the satisfaction
                    of any conditions to exercisability, including without
                    limitation, the passage of time, but without taking into
                    account potential antidilution adjustments) of such options
                    to purchase or rights to subscribe for Common Stock shall be
                    deemed to have been issued at the time such options or
                    rights were issued.

                         (2) The aggregate maximum number of shares of Common
                    Stock deliverable upon conversion of or in exchange
                    (assuming the satisfaction of any conditions to
                    convertibility or exchangeability, including, without
                    limitation, the passage of time, but without taking into
                    account potential antidilution adjustments) for any such
                    convertible or exchangeable securities or upon the exercise
                    of options to purchase or rights to subscribe for such
                    convertible or exchangeable securities and subsequent
                    conversion or exchange thereof, shall be deemed to have been
                    issued at the time such securities were issued or such
                    options or rights were issued.

                         (3) In the event of any change in the number of shares
                    of Common Stock deliverable upon exercise of such options or
                    rights or upon conversion of or in exchange for such
                    convertible or exchangeable securities, (excluding a change
                    resulting solely from the antidilution provisions thereof if
                    such change results from an event which gives rise to an
                    antidilution adjustment under this subsection 4(d)), the
                    Conversion Price of the Series A Preferred Stock, to the
                    extent in any way affected by or computed using such
                    options, rights or securities, shall be recomputed to
                    reflect such change, but no further adjustment shall be made
                    for the actual issuance of Common Stock upon the exercise of
                    any such options or rights or the conversion or exchange of
                    such securities.

                         (4) Upon the expiration of any such options or rights,
                    the termination of any such rights to convert or exchange or
                    the expiration of any options or rights related to such
                    convertible or exchangeable securities, the Conversion Price
                    of the Series A Preferred Stock, to the extent in any way
                    affected by or computed using such options, rights or
                    securities or options or rights related to such securities,
                    shall be recomputed to reflect the issuance of only the
                    number of shares of Common Stock (and convertible or
                    exchangeable securities which remain in effect) actually
                    issued upon the exercise of such options or rights, upon the
                    conversion or exchange of such securities or upon the
                    exercise of the options or rights related to such
                    securities.

                         (5) The number of shares of Common Stock deemed issued
                    pursuant to subsections 4(d)(i)(C)(1) and (2) shall be
                    appropriately adjusted to reflect any change, termination or
                    expiration of the type described in either subsection
                    4(d)(i)(C)(3) or (4).

               (ii) "Additional Stock" shall mean any shares of Common Stock
          issued (or deemed to have been issued pursuant to subsection
          4(d)(i)(C)) by the Corporation after the Purchase Date other than

                    (A) Common Stock issued pursuant to a transaction described
               in subsection 4(d)(iii) hereof; or

                    (B) shares of Common Stock issuable or issued to employees,
               advisors, consultants or outside directors of the Corporation
               directly or pursuant to a stock option plan or restricted stock
               plan approved by the Board of Directors of the Corporation so
               long as the exercise price of each such stock option is greater
               than or equal to the fair market value of the underlying Common
               Stock and the cumulative total number of shares of Common Stock
               so issuable and issued immediately prior to such issuance (and
               not repurchased at cost by the Corporation in connection with the
               termination of employment) does not exceed 8% of the outstanding
               shares of Common Stock on the date hereof; or

                    (C) Common Stock issued or issuable upon conversion of the
               Series A Preferred Stock.



                                        9

<PAGE>



               (iii) In the event the Corporation should at any time or from
          time to time after the Purchase Date fix a record date for the
          effectuation of a split or subdivision of the outstanding shares of
          Common Stock or the determination of holders of Common Stock entitled
          to receive a dividend or other distribution payable in additional
          shares of Common Stock or other securities or rights convertible into,
          or entitling the holder thereof to receive directly or indirectly,
          additional shares of Common Stock (hereinafter referred to as "Common
          Stock Equivalents") without payment of any consideration by such
          holder for the additional shares of Common Stock or the Common Stock
          Equivalents (including the additional shares of Common Stock issuable
          upon conversion or exercise thereof), then, as of such record date (or
          the date of such dividend distribution, split or subdivision if no
          record date is fixed), the Conversion Price of the Series A Preferred
          Stock shall be appropriately decreased so that the number of shares of
          Common Stock issuable on conversion of each share of such Series A
          Preferred Stock shall be increased in proportion to such increase in
          the aggregate of shares of Common Stock outstanding and those issuable
          with respect to such Common Stock Equivalents.

               (iv) If the number of shares of Common Stock outstanding at any
          time after the Purchase Date is decreased by a combination of the
          outstanding shares of Common Stock, then, following the record date of
          such combination, the Conversion Price for the Series A Preferred
          Stock shall be appropriately increased so that the number of shares of
          Common Stock issuable on conversion of each share of each series shall
          be decreased in proportion to such decrease in outstanding shares.

          (e) Other Distributions. In the event the Corporation shall declare a
     distribution payable in securities of other persons, evidences of
     indebtedness issued by the Corporation or other persons, assets (excluding
     cash dividends) or options or rights not referred to in subsection 4(d)(i),
     then, in each such case for the purpose of this subsection 4(e), the
     holders of the Series A Preferred Stock shall be entitled to a
     proportionate share of any such distribution as though they were the
     holders of the number of shares of Common Stock of the Corporation into
     which their shares of Series A Preferred Stock are convertible as of the
     record date fixed for the determination of the holders of Common Stock of
     the Corporation entitled to receive such distribution.

          (f) Recapitalizations. If at any time or from time to time there shall
     be a recapitalization of the Common Stock (other than a subdivision,
     combination or merger or sale of assets transaction provided for elsewhere
     in this Section 4 or Section 2) provision shall be made so that the holders
     of the Series A Preferred Stock shall thereafter be entitled to receive
     upon conversion of the Series A Preferred Stock the number of shares of
     stock or other securities or property of the Corporation or otherwise, to
     which a holder of Common Stock deliverable upon conversion would have been
     entitled on such recapitalization. In any such case, appropriate adjustment
     shall be made in the application of the provisions of this Section 4 with
     respect to the rights of the holders of the Series A Preferred Stock after
     the recapitalization to the end that the provisions of this Section 4
     (including adjustment of the Conversion Price then in effect and the number
     of shares issuable upon conversion of the Series A Preferred Stock) shall
     be applicable after that event as nearly equivalent as may be practicable.


                                       10

          (g) No Impairment. The Corporation will not, by amendment of its
     Certificate of Incorporation or through any reorganization,
     recapitalization, transfer of assets, consolidation, merger, dissolution,
     issue or sale of securities or any other voluntary action, avoid or seek to
     avoid the observance or performance of any of the terms to be observed or
     performed hereunder by the Corporation, but will at all times in good faith
     assist in the carrying out of all the provisions of this Section 4 and in
     the taking of all such action as may be necessary or appropriate in order
     to protect the Conversion Rights of the holders of the Series A Preferred
     Stock against impairment.

          (h) No Fractional Shares and Certificate as to Adjustments.

               (i) No fractional shares shall be issued upon the conversion of
          any share or shares of the Series A Preferred Stock, and the number of
          shares of Common Stock to be issued shall be rounded to the nearest
          whole share. Whether or not fractional shares are issuable upon such
          conversion shall be determined on the basis of the total number of
          shares of Series A Preferred Stock the holder is at the time
          converting into Common Stock and the number of shares of Common Stock
          issuable upon such aggregate conversion.

               (ii) Upon the occurrence of each adjustment or readjustment of
          the Conversion Price of any series of Series A Preferred Stock
          pursuant to this Section 4, the Corporation, at its expense, shall
          promptly compute such adjustment or readjustment in accordance with
          the terms hereof and prepare and furnish to each holder of Series A
          Preferred Stock a certificate setting forth such adjustment or
          readjustment and showing in detail the facts upon which such
          adjustment or readjustment is based. The Corporation shall, upon the
          written request at any time of any holder of Series A Preferred Stock,
          furnish or cause to be furnished to such holder a like certificate
          setting forth (A) such adjustment and readjustment, (B) the Conversion
          Price for such Series A Preferred Stock at the time in effect, and (C)
          the number of shares of Common Stock and the amount, if any, of other
          property which at the time would be received upon the conversion of a
          share of such Series A Preferred Stock. Notwithstanding anything
          contained in this paragraph to the contrary, the Corporation will not
          be liable for failure to issue a like certificate unless the holder of
          the Series A Preferred Stock has suffered actual damages by not
          receiving it.

          (i) Notices of Record Date. In the event of any taking by the
     Corporation of a record of the holders of any class of securities for the
     purpose of determining the holders thereof who are entitled to receive any
     dividend (other than a cash dividend) or other distribution, any right to
     subscribe for, purchase or otherwise acquire any shares of stock of any
     class or any other securities or property, or to receive any other right,
     the Corporation shall mail to each holder of Series A Preferred Stock, at
     least twenty (20) days prior to the date specified therein, a notice
     specifying the date on which any such record is to be taken for the purpose
     of such dividend, distribution or right, and the amount and character of
     such dividend, distribution or right.

          (j) Reservation of Stock Issuable Upon Conversion. The Corporation
     shall at all times reserve and keep available out of its authorized but
     unissued shares of Common Stock, solely for the purpose of effecting the
     conversion of the shares of the Series A Preferred Stock, such number of


                                       11

<PAGE>



     its shares of Common Stock as shall from time to time be sufficient to
     effect the conversion of all outstanding shares of the Series A Preferred
     Stock; and if at any time the number of authorized but unissued shares of
     Common Stock shall not be sufficient to effect the conversion of all then
     outstanding shares of the Series A Preferred Stock, in addition to such
     other remedies as shall be available to the holder of such Preferred Stock,
     the Corporation will take such corporate action as may, in the opinion of
     its counsel, be necessary to increase its authorized but unissued shares of
     Common Stock to such number of shares as shall be sufficient for such
     purposes, including, without limitation, engaging in all reasonable efforts
     to obtain the requisite stockholder approval of any necessary amendment to
     these provisions.

          (k) Notices. Any notice required by the provisions of this Section 4
     to be given to the holders of shares of Series A Preferred Stock shall be
     deemed given if deposited in the United States mail, postage prepaid, and
     addressed to each holder of record at his address appearing on the books of
     the Corporation.

     5. Voting Rights. Except with respect to the election of members of the
Company's Board of Directors, the Series A Preferred Stock shall be entitled to
vote on all matters as to which the holders of Common Stock shall be entitled to
vote. Each share of Series A Preferred Stock shall have that number of votes
equal to the number of shares of Common Stock into which it is then convertible.
The holders of Series A Preferred Stock shall be entitled to notice of any
stockholders' meeting in accordance with the bylaws of the Corporation, and
shall be entitled to vote upon such matters and in such manner as may be
required by law.

     6. Status of Converted Stock. In the event any shares of Series A Preferred
Stock shall be converted pursuant to Section 4 hereof, the shares so converted
shall be canceled by the Corporation and will no longer be authorized stock. The
Certificate of Incorporation of the Corporation may be appropriately amended
from time to time to effect the corresponding reduction, if any, in the
Corporation's authorized capital stock.

     7. Right to Elect Certain Directors.

     (a) Provided that there are at least five directors, for so long as the
holders of Series A Preferred Stock hold at least 5% of the Company's Series A
Preferred Stock (or 5% of the Common Stock issuable upon conversion of the
Series A Preferred Stock or upon exercise of any warrants), the holders of the
Series A Preferred Stock voting as a separate class, shall have the right to
elect one individual to the Corporation's Board of Directors and so long as the
holders of Series A Preferred Stock hold at least 10% of the Company's Series A
Preferred Stock (or 10% of the Common Stock issuable upon conversion of the
Series A Preferred Stock or upon exercise of any warrants), the holders of the
Series A Preferred Stock voting as a separate class, shall have the right to
elect two individuals to the Corporation's Board of Directors (the "Series A
Directors"), including one member who shall be elected as Co-Chairman of the
Board of Directors. The Series A Directors shall be elected at the same time as
the election of the other members of the Board of Directors. In the event of the
resignation or removal of a Series A Director, a special meeting shall be
convened at which


                                       12

<PAGE>



elections shall be held for the election of a substitute Series A Director,
provided that the holders of Series A Preferred Stock may act by unanimous
consent in lieu of such meeting.

     8. Covenants. So long as any shares of Series A Preferred Stock are
outstanding, the Company shall not without first obtaining the written consent
of the holders of at least two-thirds of the then outstanding shares of Series A
Preferred Stock:

          (a) sell, convey, or otherwise dispose of or encumber all or
     substantially all of its property or business or merge into or consolidate
     with any other corporation (other than a wholly-owned subsidiary
     corporation) or effect any transaction or series of related transactions in
     which more than fifty percent (50%) of the voting power of the Company is
     disposed of;

          (b) engage in any spin-out, distribution or sale of any business unit
     of the Company;

          (c) increase or decrease (other than by conversion) the total number
     of authorized shares of Series A Preferred Stock or amend the terms of the
     Series A Preferred Stock (or any other capital stock of the Company) so as
     to affect adversely the Series A Preferred Stock;

          (d) authorize or issue, or obligate itself to issue, any other equity
     security, including any other security or debt instrument convertible into
     or exercisable for any such equity security, having a preference over, or
     being on a parity with, the Series A Preferred Stock with respect to
     dividends, redemption or liquidation;

          (e) redeem or repurchase any outstanding equity securities of the
     Corporation except for: repurchases of unvested or restricted shares of
     Common Stock in accordance with the terms of such plan at cost from
     employees, consultants, or members of the Board of Directors pursuant to
     repurchase options of the Company (i) currently outstanding or (ii)
     hereafter entered into pursuant to a stock option plan or restricted stock
     plan approved by the Corporation's Board of Directors;

          (f) issue shares of Common Stock (or any security convertible into
     Common Stock) to employees, advisors, consultants or outside directors
     pursuant to a stock option plan or restricted stock plan if the cumulative
     total number of shares of Common Stock so issuable or issued (and not
     repurchased by the Corporation in connection with the termination of
     employment as contemplated above) exceeds 8% of the outstanding Common
     Stock on the date hereof or at the date of any Initial Public Offering, if
     such number of outstanding shares of Common Stock is greater than at the
     date hereof;

          (g) increase the authorized number of directors of the Company to more
     than five (5) members;

          (h) liquidate, dissolve or otherwise wind up the affairs of the
     Company;


                                       13

<PAGE>



          (i) enter into any transactions with affiliates of the Company except
     on arms-length terms; or

          (j) pay any dividend on or any distribution in respect of any shares
     of capital stock other than the dividends paid on the Series A Preferred
     Stock in accordance with its terms.

     C. Common Stock.

     1. Dividend Rights. Subject to the prior rights of holders of all classes
of stock at the time outstanding having prior rights as to dividends, and the
rights of series of Preferred Stock which may from time to time come into
existence, the holders of the Common Stock shall be entitled to receive, when
and as declared by the Board of Directors, out of any assets of the Corporation
legally available therefor, such dividends as may be declared from time to time
by the Board of Directors.

     2. Liquidation. Upon the liquidation, dissolution or winding up of the
Corporation, the assets of the Corporation shall be distributed as provided in
Section B2 of this Article IV hereof.

     3. Voting Rights. The holder of each share of Common Stock shall have the
right to one vote, and shall be entitled to notice of any stockholders' meeting
in accordance with the bylaws of the Corporation, and shall be entitled to vote
upon such matters and in such manner as may be provided by law.

                                  ARTICLE FIVE

                               IAT HOLDINGS, INC.

                            (A Delaware Corporation)

                                    ARTICLE I

                                  STOCKHOLDERS


     1. CERTIFICATES REPRESENTING STOCK. Every holder of stock in the
corporation shall be entitled to have a certificate signed by, or in the name
of, the corporation by the Chairman or Vice-Chairman of the Board of Directors
if any, or by the President or a Vice-President and by the Treasurer or an
Assistant Treasurer or the Secretary or an Assistant Secretary for each share of
stock owned by him in the corporation. Any and all signatures on any such
certificate may be facsimiles. In case any officer, transfer agent, or registrar
who has signed or whose facsimile signature has been placed upon a certificate
shall have ceased to be such officer, transfer agent, or registrar before such
certificate is used, it may be issued by the corporation with the same effect as
if he were such officer, transfer agent, or registrar at the date of issue.

     Whenever the corporation shall be authorized to issue more than one class
of stock or more than one series of any class of stock, and whenever the
corporation shall issue any shares of its stock as partly paid stock, the
certificates representing shares of any such class or series or of any such
partly paid stock shall set forth thereon the statements prescribed by the
General Corporation Law. Any restrictions on the transfer or registration of
transfer of any shares of stock of any class or series shall be noted
conspicuously on the certificate representing such shares.

     The corporation may issue a new certificate of stock in place of any
certificate theretofore issued by it, alleged to have been lost, stolen, or
destroyed, and the Board of Directors may require the owner of any lost, stolen,
or destroyed certificate, or his legal representative, to give the corporation a
bond sufficient to indemnify the corporation against any claim that may be made
against it on account of the alleged loss, theft, or destruction of any such
certificate or the issuance of any such new certificate.

     2. FRACTIONAL SHARE INTERESTS. The corporation may, but shall not be
required to, issue fractions of a share. If the corporation does not issue
fractions of a share, it shall (l) arrange for the disposition of fractional
interests by those entitled thereto, (2) pay in cash the fair value of fractions
of a share as of the time when those entitled to receive such fractions


                                      - 1 -

<PAGE>



are determined, or (3) issue scrip or warrants in registered or bearer form
which shall entitle the holder to receive a certificate for a full share upon
the surrender of such scrip or warrants aggregating a full share. A certificate
for a fractional share shall, but scrip or warrants shall not unless otherwise
provided therein, entitle the holder to exercise voting rights, to receive
dividends thereon, and to participate in any of the assets of the corporation in
the event of liquidation. The Board of Directors may cause scrip or warrants to
be issued subject to the conditions that they shall become void if not exchanged
for certificates representing full shares before a specified date, or subject to
the conditions that the shares for which scrip or warrants are exchangeable may
be sold by the corporation and the proceeds thereof distributed to the holders
of scrip or warrants, or subject to any other conditions which the Board of
Directors may impose.

     3. STOCK TRANSFERS. Upon compliance with provisions restricting the
transfer or registration of transfer of shares of stock, if any, transfers or
registration of transfers of shares of stock of the corporation shall be made
only on the stock ledger of the corporation by the registered holder thereof, or
by his attorney thereunto authorized by power of attorney duly executed and
filed with the Secretary of the corporation or with a transfer agent or a
registrar, if any, and on surrender of the certificate or certificates for such
shares of stock properly endorsed and the payment of all taxes due thereon.

     4. RECORD DATE FOR STOCKHOLDERS. For the purpose of determining the
stockholders entitled to notice of or to vote at any meeting of stockholders or
any adjournment thereof, or to express consent to corporate action in writing
without a meeting, or entitled to receive payment of any dividend or other
distribution or the allotment of any rights, or entitled to exercise any rights
in respect of any change, conversion, or exchange of stock or for the purpose of
any other lawful action, the directors may fix, in advance, a record date, which
shall not be more than sixty days or less than ten days before the date of such
meeting, nor more than sixty days prior to any other action. If no record date
is fixed, the record date for determining stockholders entitled to notice of or
to vote at a meeting of stockholders shall be at the close of business on the
day next preceding the day on which notice is given, or, if notice is waived, at
the close of business on the day next preceding the day on which meeting is
held; the record date for determining stockholders entitled to express consent
to corporate action in writing without a meeting, when no prior action by the
Board of Directors is necessary, shall be the day on which the first written
consent is expressed; and the record date for determining stockholders for any
other purpose shall be at the close of business on the day on which the Board of
Directors adopts the resolution relating thereto. A determination of
stockholders of record entitled to notice of or to vote at any meeting of
stockholders shall apply to any adjournment of the meeting; provided, however,
that the Board of Directors may fix a new record date for the adjourned meeting.

     5. MEANING OF CERTAIN TERMS. As used herein in respect of the right to
notice of a meeting of stockholders or a waiver thereof or to participate or
vote thereat or to consent or dissent in writing in lieu of a meeting, as the
case may be, the term "share" or "shares" or "share of stock" or "shares of
stock" or "stockholder" or "stockholders" refers to an outstanding share or
shares of stock and to a holder or holders of record of outstanding shares of
stock when the corporation is authorized to issue only one class of shares of
stock, and said


                                      - 2 -

<PAGE>



reference is also intended to include any outstanding share or shares of stock
and any holder of holders of record of outstanding shares of stock of any class
upon which or upon whom the certificate of incorporation confers such rights
where there are two or more classes or series of shares of stock or upon which
or upon whom the General Corporation Law confers such rights notwithstanding
that the certificate of incorporation may provide for more than one class or
series of shares of stock, one or more of which are limited or denied such
rights thereunder; provided, however, that no such right shall vest in the event
of an increase or a decrease in the authorized number of shares of stock of any
class or series which is otherwise denied voting rights under the provisions of
the certificate of incorporation.

     6. STOCKHOLDER MEETINGS.

     - TIME. The annual meeting shall be held on the date and at the time fixed,
from time to time, by the directors, provided, that the first annual meeting
shall be held on a date within thirteen months after the organization of the
corporation, and each successive annual meeting shall be held on a date within
thirteen months after the date of the preceding annual meeting. Special meetings
shall be held on the dates and at the times fixed by the directors.

     - PLACE. Annual meetings and special meetings shall be held at such place,
within or without the State of Delaware, as the directors may, from time to time
fix. Whenever the directors shall fail to fix such place, the meeting shall be
held at the registered office of the corporation in the State of Delaware.

     - CALL. Annual meetings and special meetings may be called by the directors
or by any officer instructed by the directors to call the meeting.

     - NOTICE OR WAIVER OF NOTICE. Written notice of all meetings shall be
given, stating the place, date, and hour of the meeting and stating the place
within the city or other municipality or community at which the list of
stockholders of the corporation may be examined. The notice of an annual meeting
shall state that the meeting is called for the election of directors and for the
transaction of other business which may properly come before the meeting, and
shall, (if any other action which could be taken at a special meeting is to be
taken at such annual meeting) state the purpose or purposes. The notice of a
special meeting shall in all instances state the purpose or purposes for which
the meeting is called. The notice of any meeting shall also include, or be
accompanied by, any additional statements, information, or documents prescribed
by the General Corporation Law. Except as otherwise provided by the General
Corporation Law, a copy of the notice of any meeting shall be given, personally
or by mail, not less than ten days nor more than sixty days before the date of
the meeting, unless the lapse of the prescribed period of time shall have been
waived, and directed to each stockholder at his record address or at such other
address which he may have furnished by request in writing to the Secretary of
the corporation. Notice by mail shall be deemed to be given when deposited, with
postage thereon prepaid, in the United States mail. If a meeting is adjourned to
another time, not more than thirty days hence, and/or to another place, and if
an announcement of the adjourned time and/or place is made at the meeting, it
shall not be necessary to give notice of the


                                      - 3 -

<PAGE>



adjourned meeting unless the directors, after adjournment, fix a new record date
for the adjourned meeting. Notice need not be given to any stockholder who
submits a written waiver of notice signed by him before or after the time stated
therein. Attendance of a stockholder at a meeting of stockholders shall
constitute a waiver of notice of such meeting, except when the stockholder
attends the meeting for the express purpose of objecting, at the beginning of
the meeting, to the transaction of any business because the meeting is not
lawfully called or convened. Neither the business to be transacted at, nor the
purpose of, any regular or special meeting of the stockholders need be specified
in any written waiver of notice.

     - STOCKHOLDER LIST. The officer who has charge of the stock ledger of the
corporation shall prepare and make, at least ten days before every meeting of
stockholders, a complete list of the stockholders, arranged in alphabetical
order, and showing the address of each stockholder and the number of shares
registered in the name of each stockholder. Such list shall be open to the
examination of any stockholder, for any purpose germane to the meeting, during
ordinary business hours, for a period of at least ten days prior to the meeting,
either at a place within the city or other municipality or community where the
meeting is to be held, which place shall be specified in the notice of the
meeting, or if not so specified, at the place where the meeting is to be held.
The list shall also be produced and kept at the time and place of the meeting
during the whole time thereof, and may be inspected by any stockholder who is
present. The stock ledger shall be the only evidence as to who are the
stockholders entitled to examine the stock ledger, the list required by this
section or the books of the corporation, or to vote at any meeting of
stockholders.

     - CONDUCT OF MEETING. Meetings of the stockholders shall be presided over
by one of the following officers in the order of seniority and if present and
acting - the Chairman of the Board, if any, the Vice-Chairman of the Board, if
any, the President, a Vice-President, or, if none of the foregoing is in office
and present and acting, by a chairman to be chosen by the stockholders. The
Secretary of the corporation, or in his absence, an Assistant Secretary, shall
act as secretary of every meeting, but if neither the Secretary nor an Assistant
Secretary is present the Chairman of the meeting shall appoint a secretary of
the meeting.

     - PROXY REPRESENTATION. Every stockholder may authorize another person or
persons to act for him by proxy in all matters in which a stockholder is
entitled to participate, whether by waiving notice of any meeting, voting or
participating at a meeting, or expressing consent or dissent without a meeting.
Every proxy must be signed by the stockholder or by his attorney-in-fact. No
proxy shall be voted or acted upon after three years from its date unless such
proxy provides for a longer period. A duly executed proxy shall be irrevocable
if it states that it is irrevocable and, if, and only as long as, it is coupled
with an interest sufficient in law to support an irrevocable power. A proxy may
be made irrevocable regardless of whether the interest with which it is coupled
is an interest in the stock itself or an interest in the corporation generally.

     - INSPECTORS. The directors, in advance of any meeting, may, but need not,
appoint one or more inspectors of election to act at the meeting or any
adjournment thereof. If an


                                      - 4 -

<PAGE>



inspector or inspectors are not appointed, the person presiding at the meeting
may, but need not, appoint one or more inspectors. In case any person who may be
appointed as an inspector fails to appear or act, the vacancy may be filled by
appointment made by the directors in advance of the meeting or at the meeting by
the person presiding thereat. Each inspector, if any, before entering upon the
discharge of his duties, shall take and sign an oath faithfully to execute the
duties of inspector at such meeting with strict impartiality and according to
the best of his ability. The inspectors, if any, shall determine the number of
shares of stock outstanding and the voting power of each, the shares of stock
represented at the meeting, the existence of a quorum, the validity and effect
of proxies, and shall receive votes, ballots or consents, hear and determine all
challenges and questions arising in connection with the right to vote, count and
tabulate all votes, ballots or consents, determine the result, and do such acts
as are proper to conduct the election or vote with fairness to all stockholders.
On request of the person presiding at the meeting, the inspector or inspectors,
if any, shall make a report in writing of any challenge, question or matter
determined by him or them and execute a certificate of any fact found by him or
them.

     - QUORUM. The holders of a majority of the outstanding voting shares of
stock shall constitute a quorum at a meeting of stockholders for the transaction
of any business. The stockholders present may adjourn the meeting despite the
absence of a quorum.

     - VOTING. Each voting share of stock shall entitle the holder thereof to
one vote. In the election of directors, a plurality of the votes cast shall
elect. Any other action shall be authorized by a majority of the votes cast
except where the General Corporation Law prescribes a different percentage of

Corporation Law and these By-laws which govern a meeting of directors held to
fill vacancies and newly created directorships in the Board or action of
disinterested directors.

directors of the corporation. The Board may designate one or more directors as
alternate members of any committee, who may replace any absent or disqualified
member at any meeting of the committee. In the absence or disqualification of
any member of any such committee or committees, the member or members thereof
present at any meeting and not disqualified from voting, whether or not he or
they constitute a quorum, may unanimously appoint another member of the Board of
Directors to act at the meeting in the place of any such absent or disqualified
member. Any such committee, to the extent provided in the resolution of the
Board, shall have and may exercise the powers and authority of the Board of
Directors in the management of the business and affairs of the corpora tion with

any committee designated by the Board, may participate in a meeting of the
Board, or any such

the Warrant as of the close of business on the Exercise Date. As soon as
practicable on or after the Exercise Date, the Warrant Agent shall deposit the

writing of the exercise of the Warrants. Promptly following, and in any event

Warrants of the Registered Holder) unless prior to the date of issuance of such
certificates the Company shall instruct the Warrant Agent to refrain from
causing such issuance of certificates pending clearance of checks received in
payment of the Purchase Price pursuant to such Warrants. Notwithstanding the
foregoing, in the case of payment made in the form of a check drawn on an
account of Royce or such other investment banks and brokerage houses as the
Company shall approve in writing to the Warrant Agent, certificates shall
immediately be issued without prior notice to the Company or any delay. Upon the
exercise of any Warrant and clearance of the funds received, the Warrant Agent
shall promptly remit the payment received for the Warrant (the "Warrant
Proceeds") to the Company or as the Company may direct in writing, subject to
the provisions of Sections 4(b) and 4(c) hereof.

     (b) If, at the Exercise Date in respect of the exercise of any Warrant
after _____________, 1998, (i) the market price of the Company's Common Stock is
greater than the then Purchase Price of the Warrant, (ii) the exercise of the
Warrant was solicited by a member of the National Association of Securities
Dealers, Inc. ("NASD") as designated in writing on the Warrant Certificate
Subscription Form, (iii) the Warrant was not held in a discretionary account,
(iv) disclosure of compensation arrangements was made both at the time of the
original offering and at the time of exercise; and (v) the solicitation of the
exercise of the Warrant was not in violation of Rule 10b-6 (as such rule or any
successor rule may be in effect as of such time of exercise) promulgated under
the Securities Exchange Act of 1934, then the Warrant Agent, simultaneously with
the distribution of the Warrant Proceeds to the Company shall, on behalf of the
Company, pay from the Warrant Proceeds, a fee of five percent (5%) (the
"Solicitation Fee") of the Purchase Price to Royce as Representative of the
Underwriters; provided that either Royce or _______ shall have solicited the
exercise of the applicable warrant as evidenced in writing in the Warrant
Certificate Subscription Form. Upon receipt of the solicitation fee from the
Warrant Agent, Royce shall in turn, if and as applicable, forward all (in the
event that _______ solicited the exercise of the applicable warrant as evidenced
in writing in the Warrant Certificate Subscription Form) or, if unclear whether
________ solicited the exercise of the applicable warrant, a portion of the
Solicitation Fee to ________, to the extent that Royce, in its sole discretion
shall determine (of which a portion may be reallowed by Royce to the dealer who
solicited the exercise which may also be an Underwriter). In the event the
Solicitation Fee is not received within five days of the date on which the
Company receives Warrant Proceeds, then the Solicitation Fee shall begin
accruing interest at an annual rate of prime plus four percent (4%), payable by
the Company to Royce, as Representative of the Underwriters, at the time Royce
receives the Solicitation Fee. Within five days after exercise the Warrant Agent
shall send to the Underwriters a copy of the reverse side of each Warrant
exercised. The Underwriters shall reimburse the Warrant Agent, upon request, for
its reasonable expenses relating to compliance with this Section 4(b). In
addition, the Underwriters and the Company may at any time during business
hours, examine the records of the Warrant Agent, including its ledger of
original Warrant Certificates returned to the Warrant Agent upon exercise of
Warrants. The provisions of this paragraph may not be modified, amended or
deleted without the prior written consent of the Underwriters.

     (c) In order to enforce the provisions of Section 4(b) above, in the event
there is any dispute or question as to the amount or payment of the Solicitation
Fee, the Warrant Agent is hereby expressly authorized to withhold payment to the
Company of the Warrant Proceeds unless and until the Company establishes an
escrow account for the purpose of depositing the entire amount of the
Solicitation Fee, which amount will be deducted from the net Warrant Proceeds to
be paid to the Company. The funds placed in the escrow account may not be
released to the Company without a written agreement from Royce that the required
Solicitation Fee has been received by Royce, as Representative of the
Underwriters.

     SECTION 5. Reservation of Shares; Listing; Payment of Taxes; etc.

     (a) The Company covenants that it will at all times reserve and keep
available out of its authorized Common Stock, solely for the purpose of issue
upon exercise of Warrants, such number of shares of Common Stock as shall then
be issuable upon the exercise of all outstanding Warrants. The Company covenants
that all shares of Common Stock which shall be issuable upon exercise of the
Warrants shall, at the time of delivery, be duly and validly issued, fully paid,
nonassessable and free from all taxes, liens and charges with respect to the
issue thereof, (other than those which the Company shall promptly pay or
discharge) and that upon issuance such shares shall be listed on each national
securities exchange, on which the other shares of outstanding Common Stock of
the Company are then listed or shall be eligible for inclusion in the Nasdaq
National Market or the Nasdaq SmallCap Market if the other shares of outstanding
Common Stock of the Company are so included.

     (b) The Company covenants that if any securities to be reserved for the
purpose of exercise of Warrants hereunder require registration with, or approval
of, any governmental authority under any federal securities law before such
securities may be validly issued or delivered upon such exercise, then the
Company will in good faith and as expeditiously as reasonably possible, endeavor
to secure such registration or approval. The Company will use reasonable efforts
to obtain appropriate approvals or registrations under state "blue sky"
securities laws. With respect to any such securities, however, Warrants may not
be exercised by, or shares of Common Stock issued to, any Registered Holder in
any state in which such exercise would be unlawful.

     (c) The Company shall pay all documentary, stamp or similar taxes and other
governmental charges that may be imposed with respect to the issuance of
Warrants, or the issuance or delivery of any shares upon exercise of the
Warrants; provided, however, that if the shares of Common Stock, are to be
delivered in a name other than the name of the Registered Holder of the Warrant
Certificate representing any Warrant being exercised, then no such delivery
shall be made unless the person requesting the same has paid to the Warrant
Agent the amount of transfer taxes or charges incident thereto, if any.

     (d) The Warrant Agent is hereby irrevocably authorized to requisition the
Company's Transfer Agent from time to time for certificates representing shares
of Common Stock issuable upon exercise of the Warrants, and the Company will
authorize the Transfer

                                                                              
                                       -6-

Agent to comply with all such proper requisitions. The Company will file with
the Warrant Agent a statement setting forth the name and address of the Transfer
Agent of the Company for shares of Common Stock issuable upon exercise of the
Warrants.

     SECTION 6. Exchange and Registration of Transfer.

     (a) Warrant Certificates may be exchanged for other Warrant Certificates
representing an equal aggregate number of Warrants of the same class or may be
transferred in whole or in part. Warrant Certificates to be exchanged shall be
surrendered to the Warrant Agent at its Corporate Office, and upon satisfaction
of the terms and provisions hereof, the Company shall execute and the Warrant
Agent shall countersign, issue and deliver in exchange therefor the Warrant
Certificate or Certificates which the Registered Holder making the exchange
shall be entitled to receive.

     (b) The Warrant Agent shall keep at its office books in which, subject to
such reasonable regulations as it may prescribe, it shall register Warrant
Certificates and the transfer thereof in accordance with its regular practice.
Upon due presentment for registration of transfer of any Warrant Certificate at
such office, the Company shall execute and the Warrant Agent shall issue and
deliver to the transferee or transferees a new Warrant Certificate or
Certificates representing an equal aggregate number of Warrants.

     (c) With respect to all Warrant Certificates presented for registration or
transfer, or for exchange or exercise, the subscription form on the reverse
thereof shall be duly endorsed, or be accompanied by a written instrument or
instruments of transfer and subscription, in form satisfactory to the Company
and the Warrant Agent, duly executed by the Registered Holder or his
attorney-in-fact duly authorized in writing.

     (d) A service charge may be imposed by the Warrant Agent for any exchange
or registration of transfer of Warrant Certificates. In addition, the Company
may require payment by such holder of a sum sufficient to cover any tax or other
governmental charge that may be imposed in connection therewith.

     (e) All Warrant Certificates surrendered for exercise or for exchange in
case of mutilated Warrant Certificates shall be promptly cancelled by the
Warrant Agent and thereafter retained by the Warrant Agent until termination of
this Agreement or resignation as Warrant Agent, or, with the prior written
consent of the Underwriters, disposed of or destroyed, at the direction of the
Company.

     (f) Prior to due presentment for registration of transfer thereof, the
Company and the Warrant Agent may deem and treat the Registered Holder of any
Warrant Certificate as the absolute owner thereof and of each Warrant
represented thereby (notwithstanding any notations of ownership or writing
thereon made by anyone other than a duly authorized officer of the Company or
the Warrant Agent) for all purposes and shall not be affected by any notice to
the contrary. The Warrants, which are being publicly offered in Units with
shares of Common

                                                                              
                                       -7-

Stock pursuant to the Underwriting Agreement, will be detachable from the Common
Stock and transferable separately therefrom beginning on the Separation Date.

     SECTION 7. Loss or Mutilation. Upon receipt by the Company and the Warrant
Agent of evidence satisfactory to them of the ownership of and loss, theft,
destruction or mutilation of any Warrant Certificate and (in case of loss, theft
or destruction) of indemnity satisfactory to them, and (in the case of
mutilation) upon surrender and cancellation thereof, the Company shall execute
and the Warrant Agent shall (in the absence of notice to the Company and/or
Warrant Agent that the Warrant Certificate has been acquired by a bona fide
purchaser) countersign and deliver to the Registered Holder in lieu thereof a
new Warrant Certificate of like tenor representing an equal aggregate number of
Warrants. Applicants for a substitute Warrant Certificate shall comply with such
other reasonable regulations and pay such other reasonable charges as the
Warrant Agent may prescribe.

     SECTION 8. Redemption.

     (a) Subject to the provisions of paragraph 2(g) hereof, on not less than
thirty (30) days notice given at any time after ____, 1998 (the "Redemption
Notice"), to Registered Holders of the Warrants being redeemed, the Warrants may
be redeemed, at the option of the Company, at a redemption price of $0.05 per
Warrant, provided the Market Price of the Common Stock receivable upon exercise
of such Warrants shall equal or exceed $16.00 with respect to the Warrants (the
"Target Price"), subject to adjustment as set forth in Section 8(f), below.
Market Price shall mean (i) the average last reported sale price of the Common
Stock, for twenty (20) consecutive business days ending on the Calculation Date
as reported by Nasdaq, if the Common Stock is traded on the Nasdaq National
Market, or (ii) the average closing bid price of the Common Stock, for twenty
(20) consecutive business days ending on the Calculation Date, as reported by
the primary exchange on which the Common Stock is traded, if the Common Stock is
traded on a national securities exchange, or by Nasdaq, if the Common Stock is
traded on the Nasdaq SmallCap Market. All Warrants of a class must be redeemed
if any of that class are redeemed, provided that the Warrants underlying the
Unit Purchase Option may only be redeemed in compliance with and subject to the
terms and conditions of the Unit Purchase Option. For purposes of this Section
8, the Calculation Date shall mean a date within 5 days of the mailing of the
Redemption Notice. The date fixed for redemption of the Warrants is referred to
herein as the "Redemption Date".

     (b) If the conditions set forth in Section 8(a) are met, and the Company
desires to exercise its right to redeem the Warrants, it shall request the
Underwriters to mail a Redemption Notice to each of the Registered Holders of
the Warrants to be redeemed, first class, postage prepaid, not later than the
thirtieth day before the date fixed for redemption, at their last address as
shall appear on the records maintained pursuant to Section 6(b). Any notice
mailed in the manner provided herein shall be conclusively presumed to have been
duly given whether or not the Registered Holder receives such notice.


                                                                              
                                       -8-

<PAGE>



     (c) The Redemption Notice shall specify (i) the redemption price, (ii) the
Redemption Date, (iii) the place where the Warrant Certificates shall be
delivered and the redemption price paid, (iv) that the Underwriters will assist
each Registered Holder of a Warrant in connection with the exercise thereof and
(v) that the right to exercise the Warrant shall terminate at 5:00 P.M. (New
York time) on the business day immediately preceding the Redemption Date. No
failure to mail such notice nor any defect therein or in the mailing thereof
shall affect the validity of the proceedings for such redemption except as to a
Registered Holder (a) to whom notice was not mailed or (b) whose notice was
defective. An affidavit of the Warrant Agent or of the Secretary or an Assistant
Secretary of the Underwriters or the Company that notice of redemption has been
mailed shall, in the absence of fraud, be prima facie evidence of the facts
stated therein.

     (d) Any right to exercise a Warrant shall terminate at 5:00 P.M. (New York
time) on the business day immediately preceding the Redemption Date. On and
after the Redemption Date, Registered Holders of the Warrants shall have no
further rights except to receive, upon surrender of the Warrant, the Redemption
Price.

     (e) From and after the Redemption Date, the Company shall, at the place
specified in the Redemption Notice, upon presentation and surrender to the
Company by or on behalf of the Registered Holder thereof of one or more Warrant
Certificates evidencing Warrants to be redeemed, deliver or cause to be
delivered to or upon the written order of such Registered Holder a sum in cash
equal to the Redemption Price of each such Warrant. From and after the
Redemption Date and upon the deposit or setting aside by the Company of a sum
sufficient to redeem all the Warrants called for redemption, such Warrants shall
expire and become void and all rights hereunder and under the Warrant
Certificates, except the right to receive payment of the Redemption Price, shall
cease.

     (f) If the shares of the Company's Common Stock are subdivided or combined
into a greater or smaller number of shares of Common Stock, the Target Prices
shall be proportionally adjusted by the ratio which the total number of shares
of Common Stock outstanding immediately prior to such event bears to the total
number of shares of Common Stock to be outstanding immediately after such event.

     SECTION 9. Adjustment of Exercise Price and Number of Shares of Common
Stock or Warrants.

     (a) Subject to the exceptions referred to in Section 9(g) below, in the
event the Company shall, at any time or from time to time after the date hereof,
sell any shares of Common Stock for a consideration per share less than the
Market Price of the Common Stock (as defined in Section 8, except that for
purposes of Section 9, the Calculation Date shall mean the date of the sale or
other transaction referred to in this Section 9) on the date of the sale or
issue any shares of Common Stock as a stock dividend to the holders of Common
Stock, or subdivide or combine the outstanding shares of Common Stock into a
greater or lesser number of shares (any such sale, issuance, subdivision or
combination being herein called a "Change of

                                                                              
                                       -9-

Shares"), then, and thereafter upon each further Change of Shares, the Purchase
Price in effect immediately prior to such Change of Shares shall be changed to a
price (including any applicable fraction of a cent) determined by multiplying
the Purchase Price in effect immediately prior thereto by a fraction, the
numerator of which shall be the sum of the number of shares of Common Stock
outstanding immediately prior to the issuance of such additional shares and the
number of shares of Common Stock which the aggregate consideration received
(determined as provided in subsection 9(f)(F) below) for the issuance of such
additional shares would purchase at the Market Price and the denominator of
which shall be the sum of the number of shares of Common Stock outstanding
immediately after the issuance of such additional shares. Such adjustment shall
be made successively whenever such an issuance is made.

     Upon each adjustment of the Purchase Price pursuant to this Section 9, the
total number of shares of Common Stock purchasable upon the exercise of each
Warrant, shall (subject to the provisions contained in Section 9(b) hereof) be
such number of shares (calculated to the nearest tenth) purchasable at the
Purchase Price in effect immediately prior to such adjustment multiplied by a
fraction, the numerator of which shall be the Purchase Price in effect
immediately prior to such adjustment and the denominator of which shall be the
Purchase Price in effect immediately after such adjustment.

     (b) The Company may elect, upon any adjustment of the Purchase Price
hereunder, to adjust the number of Warrants outstanding, in lieu of the
adjustment in the number of shares of Common Stock purchasable upon the exercise
of each Warrant as hereinabove provided, so that each Warrant outstanding after
such adjustment shall represent the right to purchase one share of Common Stock.
Each Warrant held of record prior to such adjustment of the number of Warrants
shall become that number of Warrants (calculated to the nearest tenth)
determined by multiplying the number one by a fraction, the numerator of which
shall be the Purchase Price in effect immediately prior to such adjustment and
the denominator of which shall be the Purchase Price in effect immediately after
such adjustment. Upon each adjustment of the number of Warrants pursuant to this
Section 9, the Company shall, as promptly as practicable, cause to be
distributed to each Registered Holder of Warrant Certificates on the date of
such adjustment Warrant Certificates evidencing, subject to Section 10 hereof,
the number of additional Warrants to which such Holder shall be entitled as a
result of such adjustment or, at the option of the Company, cause to be
distributed to such Holder in substitution and replacement for the Warrant
Certificates held by him prior to the date of adjustment (and upon surrender
thereof, if required by the Company) new Warrant Certificates evidencing the
number of Warrants to which such Holder shall be entitled after such adjustment.

     (c) In case of any reclassification, capital reorganization or other change
of outstanding shares of Common Stock, or in case of any consolidation or merger
of the Company with or into another corporation (other than a consolidation or
merger in which the Company is the continuing corporation and which does not
result in any reclassification, capital reorganization or other change of
outstanding shares of Common Stock), or in case of any sale or conveyance to
another corporation of the property of the Company as, or substantially as, an
entirety (other than a sale/leaseback, mortgage or other financing transaction),
the Company

                                                                              
                                      -10-

<PAGE>



shall cause effective provision to be made so that each holder of a Warrant then
outstanding shall have the right thereafter, by exercising such Warrant, to
purchase the kind and number of shares of stock or other securities or property
(including cash) receivable upon such reclassification, capital reorganization
or other change, consolidation, merger, sale or conveyance by a holder of the
number of shares of Common Stock that might have been purchased upon exercise of
such Warrant immediately prior to such reclassification, capital reorganization
or other change, consolidation, merger, sale or conveyance. Any such provision
shall include provision for adjustments that shall be as nearly equivalent as
may be practicable to the adjustments provided for in this Section 9. The
Company shall not effect any such consolidation, merger or sale unless prior to
or simultaneously with the consummation thereof the successor (if other than the
Company) resulting from such consolidation or merger or the corporation
purchasing assets or other appropriate corporation or entity shall assume, by
written instrument executed and delivered to the Warrant Agent, the obligation
to deliver to the holder of each Warrant such shares of stock, securities or
assets as, in accordance with the foregoing provisions, such holders may be
entitled to purchase and the other obligations of the Company under this
Agreement. The foregoing provisions shall similarly apply to successive
reclassifications, capital reorganizations and other changes of outstanding
shares of Common Stock and to successive consolidations, mergers, sales or
conveyances.

     (d) Irrespective of any adjustments or changes in the Purchase Price or the
number of shares of Common Stock purchasable upon exercise of the Warrants, the
Warrant Certificates theretofore and thereafter issued shall, unless the Company
shall exercise its option to issue new Warrant Certificates pursuant to Section
2(f) hereof, continue to express the Purchase Price per share, the number of
shares purchasable thereunder and the Redemption Price therefor as the Purchase
Price per share, and the number of shares purchasable and the Redemption Price
therefor were expressed in the Warrant Certificates when the same were
originally issued.

     (e) After each adjustment of the Purchase Price pursuant to this Section 9,
the Company will promptly prepare a certificate signed by the Co-Chairman or
President, and by the Treasurer or an Assistant Treasurer or the Secretary or an
Assistant Secretary, of the Company setting forth: (i) the Purchase Price as so
adjusted, (ii) the number of shares of Common Stock purchasable upon exercise of
each Warrant after such adjustment and, if the Company shall have elected to
adjust the number of Warrants, the number of Warrants to which the Registered
Holder of each Warrant shall then be entitled, and the adjustment in Redemption
Price resulting therefrom, and (iii) a statement of the facts accounting for
such adjustment and showing in detail the method of calculation and the facts
upon which such adjustment or readjustment is based, including a statement of
(a) the consideration received or to be received by the Company for any
securities issued or sold or deemed to have been issued, (b) the number of
shares of Common Stock outstanding or deemed to be outstanding, and (c) the
Purchase Price in effect immediately prior to such issue or sale and as adjusted
and readjusted (if required by Section 9) on account thereof. The Company will
promptly file such certificate with the Warrant Agent and furnish a copy thereof
to be sent by ordinary first class mail to the Underwriters and to each
Registered Holder of Warrants at his last address as it shall appear on the
registry books of the Warrant

Agent. No failure to mail such notice nor any defect therein or in the mailing
thereof shall affect the validity thereof except as to the holder to whom the
Company failed to mail such notice, or except as to the holder whose notice was
defective. The Company will, upon the written request at any time of the
Underwriters, furnish to the Underwriters a report by Rothstein, Kass & Company,
P.C., or other independent public accountants of recognized national standing
(which may be the regular auditors of the Company) selected by the Company to
verify such computation and setting forth such adjustment or readjustment and
showing in detail the method of calculation and the facts upon which such
adjustment or readjustment is based. The Company will also keep copies of all
such certificates and reports at its principal office.

     (f) For purposes of Section 9(a) and 9(b) hereof, the following provisions
(A) to (G) shall also be applicable:

          (A) The number of shares of Common Stock outstanding at any given time
     shall include shares of Common Stock owned or held by or for the account of
     the Company and the sale or issuance of such treasury shares or the
     distribution of any such treasury shares shall not be considered a Change
     of Shares for purposes of said sections.

          (B) No adjustment of the Purchase Price shall be made unless such
     adjustment would require an increase or decrease of at least $.10 in the
     Purchase Price; provided that any adjustments which by reason of this
     clause (B) are not required to be made shall be carried forward and shall
     be made at the time of and together with the next subsequent adjustment
     which, together with any adjustment(s) so carried forward, shall require an
     increase or decrease of at least $.10 in the Purchase Price then in effect
     hereunder.

          (C) In case of (1) the sale by the Company for cash (or as a component
     of a unit being sold for cash) of any rights or warrants to subscribe for
     or purchase, or any options for the purchase of, Common Stock or any
     securities convertible into or exchangeable for Common Stock without the
     payment of any further consideration other than cash, if any (such
     securities convertible, exercisable or exchangeable into Common Stock being
     herein called "Convertible Securities"), or (2) the issuance by the
     Company, without the receipt by the Company of any consideration therefor,
     of any rights or warrants to subscribe for or purchase, or any options for
     the purchase of, Common Stock or Convertible Securities, in each case, if
     (and only if) the consideration payable to the Company upon the exercise of
     such rights, warrants or options shall consist of cash, whether or not such
     rights, warrants or options, or the right to convert or exchange such
     Convertible Securities, are immediately exercisable, and the price per
     share for which Common Stock is issuable upon the exercise of such rights,
     warrants or options or upon the conversion or exchange of such Convertible
     Securities (determined by dividing (x) the minimum aggregate consideration
     payable to the Company upon the exercise of such rights, warrants or
     options, plus the

     consideration, if any, received by the Company for the issuance or sale of
     such rights, warrants or options, plus, in the case of such Convertible
     Securities, the minimum aggregate amount of additional consideration, other
     than such Convertible Securities, payable upon the conversion or exchange
     thereof, by (y) the total maximum number of shares of Common Stock issuable
     upon the exercise of such rights, warrants or options or upon the
     conversion or exchange of such Convertible Securities issuable upon the
     exercise of such rights, warrants or options) is less than the Market Price
     on the Calculation Date, then the total maximum number of shares of Common
     Stock issuable upon the exercise of such rights, warrants or options or
     upon the conversion or exchange of such Convertible Securities (as of the
     date of the issuance or sale of such rights, warrants or options) shall be
     deemed to be outstanding shares of Common Stock for purposes of Sections
     9(a) and 9(b) hereof and shall be deemed to have been sold for cash in an
     amount equal to such price per share.

          (D) In case of the sale by the Company for cash of any Convertible
     Securities, whether or not the right of conversion or exchange thereunder
     is immediately exercisable, and the price per share for which Common Stock
     is issuable upon the conversion or exchange of such Convertible Securities
     (determined by dividing (x) the total amount of consideration received by
     the Company for the sale of such Convertible Securities, plus the minimum
     aggregate amount of additional consideration, if any, other than such
     Convertible Securities, payable upon the conversion or exchange thereof, by
     (y) the total maximum number of shares of Common Stock issuable upon the
     conversion or exchange of such Convertible Securities) is less than the
     Market Price on the Calculation Date, then the total maximum number of
     shares of Common Stock issuable upon the conversion or exchange of such
     Convertible Securities (as of the date of the sale of such Convertible
     Securities) shall be deemed to be outstanding shares of Common Stock for
     purposes of Sections 9(a) and 9(b) hereof and shall be deemed to have been
     sold for cash in an amount equal to such price per share.

          (E) In case the Company shall modify the rights of conversion,
     exchange or exercise of any of the securities referred to in (C) or (D)
     above or any other securities of the Company convertible, exchangeable or
     exercisable for shares of Common Stock, for any reason other than an event
     that would require adjustment to prevent dilution, so that the
     consideration per share received by the Company after such modification is
     less than the Market Price on the Calculation Date, the Purchase Price to
     be in effect after such modification shall be determined by multiplying the
     Purchase Price in effect immediately prior to such event by a fraction, of
     which the numerator shall be the number of shares of Common Stock
     outstanding on the date prior to the modification plus the number of shares
     of Common Stock which the aggregate consideration receivable by the Company
     for the securities affected by the modification would purchase at the
     Market Price and of which the denominator shall be the number of shares of

                                                                               
                                      -13-

     Common Stock outstanding on such date plus the number of shares of Common
     Stock to be issued upon conversion, exchange or exercise of the modified
     securities at the modified rate. Such adjustment shall become effective as
     of the date upon which such modification shall take effect. On the
     expiration of any such right, warrant or option or the termination of any
     such right to convert or exchange any such Convertible Securities referred
     to in Paragraph (C) or (D) above, the Purchase Price then in effect
     hereunder shall forthwith be readjusted to such Purchase Price as would
     have obtained (a) had the adjustments made upon the issuance or sale of
     such rights, warrants, options or Convertible Securities been made upon the
     basis of the issuance of only the number of shares of Common Stock
     theretofore actually delivered (and the total consideration received
     therefor) upon the exercise of such rights, warrants or options or upon the
     conversion or exchange of such Convertible Securities and (b) had
     adjustments been made on the basis of the Purchase Price as adjusted under
     clause (a) for all transactions (which would have affected such adjusted
     Purchase Price) made after the issuance or sale of such rights, warrants,
     options or Convertible Securities.

          (F) In case of the sale for cash of any shares of Common Stock, any
     Convertible Securities, any rights or warrants to subscribe for or
     purchase, or any options for the purchase of, Common Stock or Convertible
     Securities, the consideration received by the Company therefore shall be
     deemed to be the gross sales price therefor without deducting therefrom any
     expense paid or incurred by the Company or any underwriting discounts or
     commissions or concessions paid or allowed by the Company in connection
     therewith.

          (G) In case any event shall occur as to which the provisions of
     Section 9 are not strictly applicable but the failure to make any
     adjustment would not fairly protect the purchase rights represented by the
     Warrants in accordance with the essential intent and principles of Section
     9, then, in each such case, the Board of Directors of the Company shall in
     good faith by resolution provide for the adjustment, if any, on a basis
     consistent with the essential intent and principles established in Section
     9, necessary to preserve, without dilution, the purchase rights represented
     by the Warrants. The Company will promptly make the adjustments described
     therein.

     (g) No adjustment to the Purchase Price of the Warrants or to the number of
shares of Common Stock purchasable upon the exercise of each Warrant will be
made, however,

          (i) upon the exercise of any of the options outstanding as of the date
     of this Agreement under the Company's Stock Option Plan (the "Plan") for
     officers, directors and certain other key personnel of the Company; or


                                                                              
                                      -14-

<PAGE>



          (ii) upon the issuance or exercise of any other securities which may
     hereafter be granted or exercised under the Plan or under any other
     employee benefit plan of the Company approved by the Company's
     stockholders; or

          (iii) upon the sale or exercise of the Warrants, including without
     limitation the sale or exercise of any of the Warrants comprising the Unit
     Purchase Option or upon the sale or exercise of the Unit Purchase Option;
     or

          (iv) upon the sale of any shares of Common Stock and/or Convertible
     Securities in a firm commitment underwritten public offering, including,
     without limitation, shares sold upon the exercise of any overallotment
     option granted to the underwriters in connection with such offering; or

          (v) upon the sale by the Company of any shares of Common Stock and/or
     Convertible Securities in a private placement for which the Underwriter is
     the Placement Agent; or

          (vi) upon the issuance or sale of Common Stock or Convertible
     Securities upon the exercise of any rights or warrants to subscribe for or
     purchase, or any options for the purchase of, Common Stock or Convertible
     Securities, whether or not such rights, warrants or options were
     outstanding on the date of the original sale of the Warrants or were
     thereafter issued or sold; or

          (vii) upon the issuance or sale of Common Stock upon conversion or
     exchange of any Convertible Securities, whether or not any adjustment in
     the Purchase Price was made or required to be made upon the issuance or
     sale of such Convertible Securities and whether or not such Convertible
     Securities were outstanding on the date of the original sale of the
     Warrants or were thereafter issued or sold.

     (h) As used in this Section 9, the term "Common Stock" shall mean and
include the Company's Common Stock authorized on the date of the original issue
of the Units and shall also include any capital stock of any class of the
Company thereafter authorized which shall not be limited to a fixed sum or
percentage in respect of the rights of the holders thereof to participate in
dividends and in the distribution of assets upon the voluntary liquidation,
dissolution or winding up of the Company; provided, however, that the shares
issuable upon exercise of the Warrants shall include only shares of such class
designated in the Company's Certificate of Incorporation as Common Stock on the
date of the original issue of the Units or (i), in the case of any
reclassification, change, consolidation, merger, sale or conveyance of the
character referred to in Section 9(c) hereof, the stock, securities or property
provided for in such section or (ii), in the case of any reclassification or
change in the outstanding shares of Common Stock issuable upon exercise of the
Warrants as a result of a subdivision or combination or consisting of a change
in par value, or from par value to no par value, or from no par value to par
value, such shares of Common Stock as so reclassified or changed.

                                                                               
                                      -15-

     (i) Any determination as to whether an adjustment in the Purchase Price in
effect hereunder is required pursuant to Section 9, or as to the amount of any
such adjustment, if required, shall be binding upon the holders of the Warrants
and the Company if made in good faith by the Board of Directors of the Company.

     (j) If and whenever the Company shall grant to the holders of Common Stock,
as such, rights or warrants to subscribe for or to purchase, or any options for
the purchase of, Common Stock or securities convertible into or exchangeable for
or carrying a right, warrant or option to purchase Common Stock, the Company
shall concurrently therewith grant to each Registered Holder as of the record
date for such transaction of the Warrants then outstanding, the rights, warrants
or options to which each Registered Holder would have been entitled if, on the
record date used to determine the stockholders entitled to the rights, warrants
or options being granted by the Company, the Registered Holder were the holder
of record of the number of whole shares of Common Stock then issuable upon
exercise (assuming, for purposes of this Section 9(j), that exercise of Warrants
is permissible during periods prior to the Initial Warrant Exercise Date) of his
Warrants. Such grant by the Company to the holders of the Warrants shall be in
lieu of any adjustment which otherwise might be called for pursuant to this
Section 9.

     SECTION 10. Fractional Warrants and Fractional Shares.

                  (a) If the number of shares of Common Stock purchasable upon
the exercise of each Warrant is adjusted pursuant to Section 9 hereof, the
Company nevertheless shall not be required to issue fractions of shares, upon
exercise of the Warrants or otherwise, or to distribute certificates that
evidence fractional shares. With respect to any fraction of a share called for
upon the exercise of any Warrant, the Company shall pay to the Holder an amount
in cash equal to such fraction multiplied by the current market value of such
fractional share, determined as follows:

          (1) If the Common Stock is listed on a national securities exchange or
     admitted to unlisted trading privileges on such exchange or is traded on
     the Nasdaq National Market, the current market value shall be the last
     reported sale price of the Common Stock on such exchange or market on the
     last business day prior to the date of exercise of this Warrant or if no
     such sale is made on such day, the average of the closing bid and asked
     prices for such day on such exchange or market; or

          (2) If the Common Stock is not listed or admitted to unlisted trading
     privileges on a national securities exchange or is not traded on the Nasdaq
     National Market, the current market value shall be the mean of the last
     reported bid and asked prices reported by the Nasdaq SmallCap Market or, if
     not traded thereon, by the National Quotation Bureau, Inc. on the last
     business day prior to the date of the exercise of this Warrant; or


                                                                               
                                      -16-

<PAGE>



          (3) If the Common Stock is not so listed or admitted to unlisted
     trading privileges and bid and asked prices are not so reported, the
     current market value shall be an amount determined in such reasonable
     manner as may be prescribed by the Board of Directors of the Company.

     SECTION 11. Warrant Holders Not Deemed Stockholders. No holder of Warrants
shall, as such, be entitled to vote or to receive dividends or be deemed the
holder of Common Stock that may at any time be issuable upon exercise of such
Warrants for any purpose whatsoever, nor shall anything contained herein be
construed to confer upon the holder of Warrants, as such, any of the rights of a
stockholder of the Company or any right to vote for the election of directors or
upon any matter submitted to stockholders at any meeting thereof, or to give or
withhold consent to any corporate action (whether upon any recapitalization,
issue or reclassification of stock, change of par value or change of stock to no
par value, consolidation, merger or conveyance or otherwise), or to receive
notice of meetings, or to receive dividends or subscription rights, until such
holder shall have exercised such Warrants and been issued shares of Common Stock
in accordance with the provisions hereof.

     SECTION 12. Rights of Action. All rights of action with respect to this
Agreement are vested in the respective Registered Holders of the Warrants, and
any Registered Holder of a Warrant, without consent of the Warrant Agent or of
the holder of any other Warrant, may, in his own behalf and for his own benefit,
enforce against the Company his right to exercise his Warrants for the purchase
of shares of Common Stock in the manner provided in the Warrant Certificate and
this Agreement.

     SECTION 13. Agreement of Warrant Holders. Every holder of a Warrant, by his
acceptance thereof, consents and agrees with the Company, the Warrant Agent and
every other holder of a Warrant that:

     (a) The Warrants are transferable only on the registry books of the Warrant
Agent by the Registered Holder thereof in person or by his attorney duly
authorized in writing and only if the Warrant Certificates representing such
Warrants are surrendered at the office of the Warrant Agent, duly endorsed or
accompanied by a proper instrument of transfer satisfactory to the Warrant Agent
and the Company in their sole discretion, together with payment of any
applicable transfer taxes; and

     (b) The Company and the Warrant Agent may deem and treat the person in
whose name the Warrant Certificate is registered as the holder and as the
absolute, true and lawful owner of the Warrants represented thereby for all
purposes, and neither the Company nor the Warrant Agent shall be affected by any
notice or knowledge to the contrary, except as otherwise expressly provided in
Section 7 hereof.

     SECTION 14. Cancellation of Warrant Certificates. If the Company shall
purchase or acquire any Warrant or Warrants, the Warrant Certificate or Warrant
Certificates evidencing the same shall thereupon be delivered to the Warrant
Agent and cancelled by it and

                                                                               
                                      -17-

retired. The Warrant Agent shall also cancel the Warrant Certificate or Warrant
Certificates following exercise of any or all of the Warrants represented
thereby or delivered to it for transfer or exchange.

     SECTION 15. Concerning the Warrant Agent. The Warrant Agent acts hereunder
as agent and in a ministerial capacity for the Company, and its duties shall be
determined solely by the provisions hereof. The Warrant Agent shall not, by
issuing and delivering Warrant Certificates or by any other act hereunder be
deemed to make any representations as to the validity, value or authorization of
the Warrant Certificates or the Warrants represented thereby or of any
securities or other property delivered upon exercise of any Warrant or whether
any stock issued upon exercise of any Warrant is fully paid and nonassessable.

          The Warrant Agent shall not at any time be under any duty or
     responsibility to any holder of Warrant Certificates to make or cause to be
     made any adjustment of the Purchase Price or the Redemption Price provided
     in this Agreement, or to determine whether any fact exists which may
     require any such adjustments, or with respect to the nature or extent of
     any such adjustment, when made, or with respect to the method employed in
     making the same. It shall not (i) be liable for any recital or statement of
     facts contained herein or for any action taken, suffered or omitted by it
     in reliance on any Warrant Certificate or other document or instrument
     believed by it in good faith to be genuine and to have been signed or
     presented by the proper party or parties, (ii) be responsible for any
     failure on the part of the Company to comply with any of its covenants and
     obligations contained in this Agreement or in any Warrant Certificate, or
     (iii) be liable for any act or omission in connection with this Agreement
     except for its own negligence or wilful misconduct.

          The Warrant Agent may at any time consult with counsel satisfactory to
     it (who may be counsel for the Company) and shall incur no liability or
     responsibility for any action taken, suffered or omitted by it in good
     faith in accordance with the opinion or advice of such counsel.

          Any notice, statement, instruction, request, direction, order or
     demand of the Company shall be sufficiently evidenced by an instrument
     signed by the Co-Chairman of the Board, President, any Vice President, its
     Secretary, or Assistant Secretary, (unless other evidence in respect
     thereof is herein specifically prescribed). The Warrant Agent shall not be
     liable for any action taken, suffered or omitted by it in accordance with
     such notice, statement, instruction, request, direction, order or demand
     believed by it to be genuine.

          The Company agrees to pay the Warrant Agent reasonable compensation
     for its services hereunder and to reimburse it for its reasonable expenses
     hereunder; it further agrees to indemnify the Warrant Agent and save it
     harmless against any and all losses, expenses and liabilities, including
     judgments, costs and counsel fees, for anything done or omitted by the
     Warrant Agent in the execution of its duties and powers hereunder except
     losses, expenses and liabilities arising as a result of the Warrant Agent's
     negligence or wilful misconduct.


                                                                               
                                      -18-

          The Warrant Agent may resign its duties and be discharged from all
     further duties and liabilities hereunder (except liabilities arising as a
     result of the Warrant Agent's own negligence or wilful misconduct), after
     giving 30 days' prior written notice to the Company. At least 15 days prior
     to the date such resignation is to become effective, the Warrant Agent
     shall cause a copy of such notice of resignation to be mailed to the
     Registered Holder of each Warrant Certificate at the Company's expense.
     Upon such resignation, or any inability of the Warrant Agent to act as such
     hereunder, the Company shall appoint a new warrant agent in writing. If the
     Company shall fail to make such appointment within a period of 15 days
     after it has been notified in writing of such resignation by the resigning
     Warrant Agent, then the Registered Holder of any Warrant Certificate may
     apply to any court of competent jurisdiction for the appointment of a new
     warrant agent. Any new warrant agent, whether appointed by the Company or
     by such a court, shall be a bank or trust company having a capital and
     surplus, as shown by its last published report to its stockholders, of not
     less than $10,000,000 or a stock transfer company that is a registered
     transfer agent under the Securities Exchange Act of 1934. After acceptance
     in writing of such appointment by the new warrant agent is received by the
     Company, such new warrant agent shall be vested with the same powers,
     rights, duties and responsibilities as if it had been originally named
     herein as the Warrant Agent, without any further assurance, conveyance, act
     or deed; but if for any reason it shall be necessary or expedient to
     execute and deliver any further assurance, conveyance, act or deed, the
     same shall be done at the expense of the Company and shall be legally and
     validly executed and delivered by the resigning Warrant Agent. Not later
     than the effective date of any such appointment the Company shall file
     notice thereof with the resigning Warrant Agent and shall forthwith cause a
     copy of such notice to be mailed to the Registered Holder of each Warrant
     Certificate.

          Any corporation into which the Warrant Agent or any new warrant agent
     may be converted or merged or any corporation resulting from any
     consolidation to which the Warrant Agent or any new warrant agent shall be
     a party or any corporation succeeding to the trust business of the Warrant
     Agent shall be a successor warrant agent under this Agreement without any
     further act, provided that such corporation is eligible for appointment as
     successor to the Warrant Agent under the provisions of the preceding
     paragraph. Any such successor warrant agent shall promptly cause notice of
     its succession as warrant agent to be mailed to the Company and to the
     Registered Holder of each Warrant Certificate.

          The Warrant Agent, its subsidiaries and affiliates, and any of its or
     their officers or directors, may buy and hold or sell Warrants or other
     securities of the Company and otherwise deal with the Company in the same
     manner and to the same extent and with like effects as though it were not
     Warrant Agent. Nothing herein shall preclude the Warrant Agent from acting
     in any other capacity for the Company or for any other legal entity.

     SECTION 16. Modification of Agreement. Subject to the provisions of Section
4(b), the parties hereto and the Company may by supplemental agreement make any
changes or corrections in this Agreement (i) that they shall deem appropriate to
cure any ambiguity or to correct any defective or inconsistent provision or
manifest mistake or error herein contained; (ii) to reflect an increase in the
number of Warrants which are to be governed

securities which includes Warrants or (b) a subsequent private placement of
Company securities which includes Warrants, in either case having the same terms
and conditions as the Warrants, respectively, originally covered by or
subsequently added to this Agreement under this Section 16, provided, however,
that in the case of a private placement, the amendment to this Agreement will be
effective only at such time as the resale of such Warrants, as well as the
securities underlying such Warrants is covered by an effective registration
statement under the Act; or (iii) that they may deem necessary or desirable and
which shall not adversely affect the interests of the holders of Warrant
Certificates; provided, however, that this Agreement shall not otherwise be
modified, supplemented or altered in any respect except with the consent in
writing of the Registered Holders of Warrant Certificates representing not less
than 50% of the Warrants then outstanding; and provided, further, that no change
in the number or nature of the securities purchasable upon the exercise of any
Warrant, or the Purchase Price therefor, or the acceleration of the Warrant
Expiration Date, shall be made without the consent in writing of the Registered
Holder of the Warrant Certificate representing such Warrant, other than such
changes as are specifically prescribed by this Agreement as originally executed
or are made in compliance with applicable law.

Certificates . Nothing in this Agreement is intended or shall be construed to
confer upon any other person any right, remedy or claim, in equity or at law, or
to impose upon any other person any duty, liability or obligation.

     SECTION 20. Termination. This Agreement shall terminate at the close of
business on the earlier of the Warrant Expiration Date or the date upon which
all Warrants (including the warrants issuable upon exercise of the Unit Purchase
Options) have been exercised, except that the Warrant Agent shall account to the
Company for cash held by it and the provisions of Section 15 hereof shall
survive such termination.

                                                                   310,000 Units


                              IAT Multimedia, Inc.
                              Unit Purchase Option
                            Dated: ___________, 1997.


     THIS CERTIFIES THAT Royce Investment Group, Inc. (herein sometimes called
the "Holder") is entitled to purchase from IAT Multimedia, Inc., a Delaware
corporation (hereinafter called the "Company"), at the prices and during the
periods as hereinafter specified, up to three hundred and ten thousand (310,000)
Units ("Units"), each Unit consisting of one share of the Company's Common
Stock, $.01 par value, as now constituted ("Common Stock") and one warrant
("Warrants"). Each Warrant is exercisable to purchase one share of Common Stock
at an exercise price of $_______, subject to adjustment, at any time commencing
one year from the effective date of the Registration Statement (as defined
below), but not earlier than the Separation Date (as defined in the Warrant
Agreement) until _______ , 2002.

     The Units have been registered under a Registration Statement on Form S-1,
(File No. 333-_______ ) declared effective by the Securities and Exchange
Commission on _______ (the "Registration Statement"). This Option, together with
options of like tenor, constituting in the aggregate options (the "Options") to
purchase 310,000 Units, subject to adjustment in accordance with Section 8 of
this Option (the "Option Units"), was originally issued pursuant to an
underwriting agreement between the Company and Royce Investment Group, Inc., as
representative of the Underwriters named in Schedule A thereto (the
"Underwriters"), in connection with a public offering (the "Offering") of
3,100,000 Units (the "Public Units") through the Underwriters, in consideration
of $310 received for the Options.

     Except as specifically otherwise provided herein, the Common Stock and the
Warrants issued pursuant to the option herein granted (the "Option") shall bear
the same terms and conditions as described under the caption "Description of
Securities" in the Registration Statement, and the Warrants shall be governed by
the terms of the Warrant Agreement dated as of __________, 1997 executed in
connection with such public offering (the "Warrant Agreement"), and except that
(i) the holder shall have registration rights under the Securities Act of 1933,
as amended (the "Act"), for the Option, the Common Stock and the Warrants
included in the Option Units, and the shares of Common Stock underlying the
Warrants, as more fully described in Section 6 of this Option and (ii) the
Warrants issuable upon exercise of the Option will be subject to redemption by
the Company pursuant to the Warrant Agreement at any time after the Option has
been exercised and the Warrants underlying the Option Units are outstanding. Any
such redemption shall be on the same terms and conditions as the Warrants
included in the Public Units (the "Public Warrants"). The Company will list the
Common Stock underlying this Option and, at the Holder's request the Warrants,
on the Nasdaq National Market,

                                                                              

<PAGE>



the Nasdaq Small Cap Market or such other exchange or market as the Common Stock
or Public Warrants may then be listed or quoted. In the event of any extension
of the expiration date or reduction of the exercise price of the Public
Warrants, the same changes to the Warrants included in the Option Units shall be
simultaneously effected.

     1. The rights represented by this Option shall be exercised at the prices,
subject to adjustment in accordance with Section 8 of this Option ("the
"Exercise Price"), and during the periods as follows:

          (a) During the period from _________, 1997 to _________, 1998,
     inclusive, the Holder shall have no right to purchase any Option Units
     hereunder, except that in the event of any merger, consolidation or sale of
     all or substantially all the capital stock or assets of the Company or in
     the case of any statutory exchange of securities with another corporation
     (including any exchange effected in connection with a merger of another
     corporation into the Company) subsequent to _________, 1997, the Holder
     shall have the right to exercise this Option and the Warrants included
     herein at such time and receive the kind and amount of shares of stock and
     other securities and property (including cash) which a holder of the number
     of shares of Common Stock underlying this Option and the Warrants included
     in this Option would have owned or been entitled to receive had this Option
     been exercised immediately prior thereto.

          (b) Between _________, 1998, and _________, 2002 inclusive, the Holder
     shall have the option to purchase Option Units hereunder at a price of
     $_______ per Unit. For purposes of the adjustments under Section 8 hereof,
     the Per Share Exercise Price shall be deemed to be $_______, subject to
     further adjustment as provided in such Section 8.

          (c) After _________, 2002 the Holder shall have no right to purchase
     any Units hereunder.

     2. (a) The rights represented by this Option may be exercised at any time
within the period above specified, in whole or in part, by (i) the surrender of
this Option (with the purchase form at the end hereof properly executed) at the
principal executive office of the Company (or such other office or agency of the
Company as it may designate by notice in writing to the Holder at the address of
the Holder appearing on the books of the Company); and (ii) payment to the
Company of the exercise price then in effect for the number of Option Units
specified in the above-mentioned purchase form together with applicable stock
transfer taxes, if any. This Option shall be deemed to have been exercised, in
whole or in part to the extent specified, immediately prior to the close of
business on the date this Option is surrendered and payment is made in
accordance with the foregoing provisions of this Section 2, and the person or
persons in whose name or names the certificates for shares of Common Stock and
Warrants shall



                                       -2-

<PAGE>



be issuable upon such exercise shall become the holder or holders of record of
such Common Stock and Warrants at that time and date. The certificates for the
Common Stock and Warrants so purchased shall be delivered to the Holder as soon
as practicable but not later than ten (10) days after the rights represented by
this Option shall have been so exercised.

     (b) At any time during the period above specified, during which this Option
may be exercised, the Holder may, at its option, exchange this Option, in whole
or in part (an "Option Exchange"), into the number of Option Units determined in
accordance with this Section (b), by surrendering this Option at the principal
office of the Company or at the office of its stock transfer agent, accompanied
by a notice stating such Holder's intent to effect such exchange, the number of
Option Units into which this Option is to be exchanged and the date on which the
Holder requests that such Option Exchange occur (the "Notice of Exchange"). The
Option Exchange shall take place on the date specified in the Notice of Exchange
or, if later, the date the Notice of Exchange is received by the Company (the
"Exchange Date"). Certificates for the shares of Common Stock and Warrants
issuable upon such Option Exchange and, if applicable, a new Option of like
tenor evidencing the balance of the Option Units remaining subject to this
Option, shall be issued as of the Exchange Date and delivered to the Holder
within seven (7) days following the Exchange Date. In connection with any Option
Exchange, this Option shall represent the right to subscribe for and acquire the
number of Option Units (rounded to the next highest integer) equal to (x) the
number of Option Units specified by the Holder in its Notice of Exchange up to
the maximum number of Option Units subject to this option (the "Total Number")
less (y) the number of Option Units equal to the quotient obtained by dividing
(A) the product of the Total Number and the existing Exercise Price by (B) the
Fair Market Value. "Fair Market Value" shall mean first, if there is a trading
market as indicated in Subsection (i) below for the Units, such Fair Market
Value of the Units and if there is no such trading market in the Units, then
Fair Market Value shall have the meaning indicated in Subsections (ii) through
(v) below for the aggregate value of all shares of Common Stock and Warrants
which comprise a Unit:

          (i) If the Units are listed on a national securities exchange or
     listed or admitted to unlisted trading privileges on such exchange or
     listed for trading on the Nasdaq National Market or the Nasdaq Small Cap
     Market, the Fair Market Value shall be the average of the last reported
     sale prices or the average of the means of the last reported bid and asked
     prices, respectively, of the Units on such exchange or market for the
     twenty (20) business days ending on the last business day prior to the
     Exchange Date; or

          (ii) If the Common Stock or Warrants are listed on a national
     securities exchange or admitted to unlisted trading privileges on such
     exchange or listed for trading on the Nasdaq National Market or the Nasdaq
     Small Cap Market, the Fair Market Value shall be the average of the last
     reported sale prices or the average of the means of the last reported bid
     and asked prices, respectively, of Common Stock or Warrants, respectively,
     on such exchange or market for the twenty (20) business days ending on the
     last business day prior to the Exchange Date; or

                                       -3-

<PAGE>



          (iii) If the Common Stock or Warrants are not so listed or admitted to
     unlisted trading privileges, the Fair Market Value shall be the average of
     the means of the last reported bid and asked prices of the Common Stock or
     Warrants, respectively, for the twenty (20) business days ending on the
     last business day prior to the Exchange Date; or

          (iv) If the Common Stock is not so listed or admitted to unlisted
     trading privileges and bid and asked prices are not so reported, the Fair
     Market Value shall be an amount, not less than book value thereof as at the
     end of the most recent fiscal year of the Company ending prior to the
     Exchange Date, determined in such reasonable manner as may be prescribed by
     the Board of Directors of the Company; or

          (v) If the Warrants are not so listed or admitted to unlisted trading
     privileges, and bid and asked prices are not so reported for Warrants, then
     Fair Market Value for the Warrants shall be an amount equal to the
     difference between (i) the Fair Market Value of the shares of Common Stock
     and Warrants which may be received upon the exercise of the Warrants, as
     determined herein, and (ii) the Warrant Exercise Price.

     3. Neither this Option nor the underlying securities shall be transferred,
sold, assigned, or hypothecated for a period of one year commencing on the
effective date of the Registration Statement except that they may be transferred
to successors of the Holder, and may be assigned in whole or in part to any
person who is an officer of the Holder, any member participating in the selling
group relating to the Offering or any officer of such selling group member. Any
such assignment shall be effected by the Holder (i) executing the form of
assignment at the end hereof and (ii) surrendering this Option for cancellation
at the office or agency of the Company referred to in Section 2 hereof,
accompanied by a certificate (signed by an officer of the Holder if the Holder
is a corporation), stating that each transferee is a permitted transferee under
this Section 3 hereof; whereupon the Company shall issue, in the name or names
specified by the Holder (including the Holder) a new Option or Options of like
tenor and representing in the aggregate rights to purchase the same number of
Option Units as are purchasable hereunder.

     4. The Company covenants and agrees that all shares of Common Stock which
may be issued as part of the Option Units purchased hereunder and the Common
Stock which may be issued upon exercise of the Warrants will, upon issuance, be
duly and validly issued, fully paid and nonassessable and no personal liability
will attach to the holder thereof. The Company further covenants and agrees that
during the periods within which this Option may be exercised, the Company will
at all times have authorized and reserved a sufficient number of shares of its
Common Stock to provide for the exercise of this Option and that it will have
authorized and reserved a sufficient number of shares of Common Stock for
issuance upon exercise of the Warrants included in the Option Units.


                                                                        

                                       -4-

     5. This Option shall not entitle the Holder to any voting rights or any
other rights, or subject to the Holder to any liabilities, as a stockholder of
the Company.

     6. (a) The Company shall advise the Holder or its transferee, whether the
Holder holds the Option or has exercised the Option and holds Option Units or
any of the securities underlying the Option Units, by written notice at least
four weeks prior to the filing of any post-effective amendment to the
Registration Statement or of any new registration statement or post-effective
amendment thereto under the Act covering any securities of the Company, for its
own account or for the account of others, and will for a period of seven years
from the effective date of the Registration Statement, upon the request of the
Holder, include in any such post-effective amendment or registration statement,
such information as may be required to permit a public offering of the Option,
all or any of the Option Units, the Common Stock or Warrants included in the
Option Units or the Common Stock issuable upon the exercise of the Warrants (the
"Registrable Securities").

     (b) If any 50% holder (as defined below) shall give notice to the Company
at any time to the effect that such holder desires to register under the Act
this Option, the Option Units or any of the underlying securities contained in
the Option Units under such circumstances that a public distribution (within the
meaning of the Act) of any such securities will be involved then the Company
will promptly, but no later than two weeks after receipt of such notice, file a
post-effective amendment to the current Registration Statement or a new
registration statement on Form S-1 or such other form as the holder requests
pursuant to the Act, to the end that the Option, the Option Units and/or any of
the securities underlying the Option Units may be publicly sold under the Act as
promptly as practicable thereafter and the Company will use its best efforts to
cause such registration to become and remain effective (including the taking of
such steps as are necessary to obtain the removal of any stop order); provided,
that such holder shall furnish the Company with appropriate information in
connection therewith as the Company may reasonably request in writing. The 50%
holder may, at its option, request the filing of a post-effective amendment to
the current Registration Statement or a new registration statement under the Act
on one occasion during the four year period beginning one year from the
effective date of the Registration Statement. The Holder may, at its option
request the registration of the Option and/or any of the securities underlying
the Option in a registration statement made by the Company as contemplated by
Section 6(a) or in connection with a request made pursuant to this Section 6(b)
prior to acquisition of the Option Units issuable upon exercise of the Option
and even though the Holder has not given notice of exercise of the Option. The
50% holder may, at its option, request such post-effective amendment or new
registration statement during the described period with respect to the Option,
the Option Units as a unit, or separately as to the Common Stock and/or Warrants
included in the Option Units and/or the Common Stock issuable upon the exercise
of the Warrants, and such registration rights may be exercised by the 50% holder
prior to or subsequent to the exercise of the Option.

     Within ten days after receiving any such notice pursuant to this Section
6(b), the Company shall give notice to the other holders of the Options,
advising that the Company is proceeding with such post-effective amendment or
registration statement and offering to include

                                                                        

                                       -5-

therein the securities underlying the Options of the other holders, provided
that they shall furnish the Company with such appropriate information (relating
to the intentions of such holders) in connection therewith as the Company shall
reasonably request in writing. All costs and expenses of the first such
post-effective amendment or new registration statement under this paragraph 6(b)
shall be borne by the Company, except that the holders shall bear the fees of
their own counsel and any underwriting discounts or commissions applicable to
any of the securities sold by them. If the Company determines to include
securities to be sold by it in any registration statement originally requested
pursuant to this Section 6(b), such registration shall instead be deemed to have
been a registration under Section 6(a) and not under this Section 6(b).

     The Company will maintain such registration statement or post-effective
amendment current under the Act for a period of at least six months (and for up
to an additional three months if requested by the Holder) from the effective
date thereof.

     (c) The term "50% holder" as used in this Section 6 shall mean the holder
of at least 50% of the Common Stock and the Warrants underlying the Options
(considered in the aggregate) and shall include any owner or combination of
owners of such securities, which ownership shall be calculated by determining
the number of shares of Common Stock held by such owner or owners as well as the
number of shares then issuable upon exercise of the Warrants.

     (d) Whenever pursuant to Section 6 a registration statement relating to any
Registrable Securities is filed under the Act, amended or supplemented, the
Company shall (i) supply prospectuses and such other documents as the Holder may
request in order to facilitate the public sale or other disposition of the
Registrable Securities, (ii) use its best efforts to register and qualify any of
the Registrable Securities for sale in such states as such Holder designates,
(iii) furnish indemnification in the manner provided in Section 7 hereof, (iv)
notify each Holder of Registrable Securities at any time when a prospectus
relating thereto is required to be delivered under the Securities Act, of the
happening of any event as a result of which the prospectus included in such
registration statement, as then in effect, contains an untrue statement of a
material fact or omits to state a material fact required to be stated therein or
necessary to make the statements therein not misleading and, at the request of
any such Holder, prepare and furnish to such Holder a reasonable number of
copies of a supplement to or an amendment of such prospectus as may be necessary
so that, as thereafter delivered to the purchasers of such Registrable
Securities, such prospectus shall not included an untrue statement of a material
fact or omit to state material fact required to be stated therein or necessary
to make the statements therein not misleading and (v) do any and all other acts
and things which may be necessary or desirable to enable such Holders to
consummate the public sale or other disposition of the Registrable Securities,
The Holder shall furnish appropriate information in connection therewith and
indemnification as set forth in Section 7.

     (e) The Company shall not permit the inclusion of any securities other than
the Registrable Securities to be included in any registration statement filed
pursuant to Section 6(b) hereof without the prior written consent of the 50%
holder.

                                                                             

                                       -6-

     (f) The Company shall furnish to each Holder participating in the offering
and to each underwriter, if any, a signed counterpart, addressed to such Holder
or underwriter, of (i) an opinion of counsel to the Company, dated the effective
date of such registration statement (or, if such registration includes an
underwritten public offering, an opinion dated the date of the closing under the
underwriting agreement), and (ii) if such registration includes an underwritten
public offering, a "cold comfort" letter dated the effective date of such
registration statement and dated the date of the closing under the underwriting
agreement signed by the independent public accountants who have issued a report
on the Company's financial statements included in such registration statement,
in each case covering substantially the same matters with respect to such
registration statement (and the prospectus included therein) and, in the case of
such accountants' letter, with respect to events subsequent to the date of such
financial statements, as are customarily covered in opinions of issuer's counsel
and in accountants' letters delivered to underwriters in underwritten public
offerings of securities.

     (g) The Company shall deliver promptly to each Holder participating in the
offering requesting the correspondence and memoranda described below and to the
managing underwriter copies of all correspondence between the Commission and the
Company, its counsel or auditors and all memoranda relating to discussions with
the Commission or its staff with respect to the registration statement and
permit each Holder and underwriter to do such investigation, upon reasonable
advance notice, with respect to information contained in or omitted from the
registration statement as it deems reasonable necessary to comply with
applicable securities laws or rules of the National Association of Securities
Dealers, Inc. ("NASD"). Such investigation shall include access to
non-confidential books, records and properties and opportunities to discuss the
business of the Company with its officers and independent auditors, all to such
reasonable extent and at such reasonable times as any such Holder shall
reasonably request.

     7. (a) Whenever pursuant to Section 6 a registration statement relating to
the Registrable Securities is filed under the Act, amended or supplemented, the
Company will indemnify and hold harmless each holder of the Registrable
Securities covered by such registration statement, amendment or supplement (such
holder being hereinafter called the "Distributing Holder"), and each person, if
any, who controls (within the meaning of the Act) the Distributing Holder, and
each underwriter (within the meaning of the Act) of such securities and each
person, if any, who controls (within the meaning of the Act) any such
underwriter, against any losses, claims, damages or liabilities, joint or
several, to which the Distributing Holder, any such controlling person or any
such underwriter may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any untrue statement or alleged untrue statement of any
material fact contained in any such registration statement or any preliminary
prospectus or final prospectus constituting a part thereof or any amendment or
supplement thereto, or arise out of or are based upon the omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading; and will reimburse the Distributing Holder
and each such controlling person and underwriter for any legal or other expenses

                                                                     

                                       -7-

<PAGE>



reasonably incurred by the Distributing Holder or such controlling person or
underwriter in connection with investigating or defending any such loss, claim,
damage, liability or action; provided, however, that the Company will not be
liable in any such case to the extent that any such loss, claim, damage or
liability arises out of or is based upon an untrue statement or alleged untrue
statement or omission or alleged omission made in said registration statement,
said preliminary prospectus, said final prospectus or said amendment or
supplement in reliance upon and in conformity with written information furnished
by such Distributing Holder specifically for use in the preparation thereof.

     (b) If requested by the Company prior to the filing of any registration
statement covering the Registrable Securities, each Distributing Holder will
agree, severally but not jointly, to indemnify and hold harmless the Company
against any losses, claims, damages or liabilities to which the Company may
become subject, under the Act or otherwise, insofar as such losses, claims,
damages or liabilities arise out of or are based upon any untrue or alleged
untrue statement of any material fact contained in said registration statement,
said preliminary prospectus, said final prospectus, or said amendment or
supplement, or arise out of or are based upon the omission or the alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, in each case to the
extent, but only to the extent that such untrue statement or alleged untrue
statement or omission or alleged omission was made in said registration
statement, said preliminary prospectus, said final prospectus or said amendment
or supplement in reliance upon and in conformity with written information
furnished by such Distributing Holder specifically for use in the preparation
thereof; except that the maximum amount which may be recovered from the
Distributing Holder pursuant to this Section 7 or otherwise shall be limited to
the amount of net proceeds received by the Distributing Holder from the sale of
the Registrable Securities.

     (c) Promptly after receipt by an indemnified party under this Section 7 of
notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against any indemnifying party, give the
indemnifying party notice of the commencement thereof; but the omission so to
notify the indemnifying party will not relieve it from any liability which it
may have to any indemnified party otherwise than under this Section 7.

     (d) In case any such action is brought against any indemnified party, and
it notifies an indemnifying party of the commencement thereof, the indemnifying
party will be entitled to participate in, and, to the extent that it may wish,
jointly with any other indemnifying party similarly notified to assume the
defense thereof, with counsel reasonably satisfactory to such indemnified party,
and after notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof, the indemnifying party will not be
liable to such indemnified party under this Section 7 for any legal or other
expenses subsequently incurred by such indemnified party in connection with the
defense thereof other than reasonable costs of investigation.

     (8) In addition to the provisions of Section 1(a) of this Option, the
Exercise Price in effect at any time and the number and kind of securities
purchasable upon the exercise of the Options shall be subject to adjustment from
time to time upon the happening of certain events as follows:

          (a) In case the Company shall (i) declare a dividend or make a
     distribution on its outstanding shares of Common Stock in shares of Common
     Stock, (ii) subdivide or reclassify its outstanding shares of Common Stock
     into a greater number of shares, or (iii) combine or reclassify its
     outstanding shares of Common Stock into a smaller number of shares, the
     Exercise Price in effect at the time of the record date for such dividend
     or distribution or of the effective date of such subdivision, combination
     or reclassification shall be adjusted so that it shall equal the price
     determined by multiplying the Exercise Price by a fraction, the denominator
     of which shall be the number of shares of Common Stock outstanding after
     giving effect to such action, and the numerator of which shall be the
     number of shares of Common Stock outstanding immediately prior to such
     action. Such adjustment shall be made successively whenever any event
     listed above shall occur.

          (b) Whenever the Exercise Price payable upon exercise of each Option
     is adjusted pursuant to Subsection (a) above, (i) the number of shares of
     Common Stock included in an Option Unit shall simultaneously be adjusted by
     multiplying the number of shares of Common Stock included in Option Unit
     immediately prior to such adjustment by the Exercise Price in effect
     immediately prior to such adjustment and dividing the product so obtained
     by the Exercise Price, as adjusted and (ii) the number of shares of Common
     Stock or other securities issuable upon exercise of the Warrants included
     in the Option Units and the exercise price of such Warrants shall be
     adjusted in accordance with the applicable terms of the Warrant Agreement.

          (c) No adjustment in the Exercise Price shall be required unless such
     adjustment would require an increase or decrease of at least five cents
     ($0.05) in such price; provided, however, that any adjustments which by
     reason of this Subsection (c)(i) are not required to be made shall be
     carried forward and taken into account in any subsequent adjustment
     required to be made hereunder. All calculations under this Section 8 shall
     be made to the nearest cent or to the nearest one-hundredth of a share, as
     the case may be. Anything in this Section 8 to the contrary
     notwithstanding, the Company shall be entitled, but shall not be required,
     to make such changes in the Exercise Price, in addition to those required
     by this Section 8, as it shall determine, in its sole discretion, to be
     advisable in order that any dividend or distribution in shares of Common
     Stock, or any subdivision, reclassification or combination of Common Stock,
     hereafter made by the Company shall not result in any Federal Income tax
     liability to the holders of

                                       
                                       -9-

<PAGE>



     Common Stock or securities convertible into Common Stock (including
     Warrants issuable upon exercise of this Option).

          (d) Whenever the Exercise Price is adjusted, as herein provided, the
     Company shall promptly but no later than 10 days after any request for such
     an adjustment by the Holder, cause a notice setting forth the adjusted
     Exercise Price and adjusted number of Option Units issuable upon exercise
     of each Option and, if requested, information describing the transactions
     giving rise to such adjustments, to be mailed to the Holders, at the
     address set forth herein, and shall cause a certified copy thereof to be
     mailed to its transfer agent, if any. The Company may retain a firm of
     independent certified public accountants selected by the Board of Directors
     (who may be the regular accountants employed by the Company) to make any
     computation required by this Section 8, and a certificate signed by such
     firm shall be conclusive evidence of the correctness of such adjustment.

          (e) In the event that at any time, as a result of an adjustment made
     pursuant to Subsection (a) above, the Holder of this Option thereafter
     shall become entitled to receive any shares of the Company, other than
     Common Stock, thereafter the number of such other shares so receivable upon
     exercise of this Option shall be subject to adjustment from time to time in
     a manner and on terms as nearly equivalent as practicable to the provisions
     with respect to the Common Stock contained in Subsections (a) to (d),
     inclusive above.

          (f) In case any event shall occur as to which the other provisions of
     this Section 8 or Section 1(a) hereof are not strictly applicable but as to
     which the failure to make any adjustment would not fairly protect the
     purchase rights represented by this Option in accordance with the essential
     intent and principles hereof then, in each such case, the Holders of
     Options representing the right to purchase a majority of the Option Units
     may appoint a firm of independent public accountants reasonably acceptable
     to the Company, which shall give their opinion as to the adjustment, if
     any, on a basis consistent with the essential intent and principles
     established herein, necessary to preserve the purchase rights represented
     by the Options. Upon receipt of such opinion, the Company will promptly
     mail a copy thereof to the Holder of this Option and shall make the
     adjustments described therein. The fees and expenses of such independent
     public accountants shall be borne by the Company.

     9. This Agreement shall be governed by and in accordance with the laws of
the State of New York, without giving effect to the principles of conflicts of
law thereof.

                                                                   310,000 Units


                              IAT Multimedia, Inc.
                              Unit Purchase Option
                            Dated: ___________, 1997.


     THIS CERTIFIES THAT Royce Investment Group, Inc. (herein sometimes called
the "Holder") is entitled to purchase from IAT Multimedia, Inc., a Delaware
corporation (hereinafter called the "Company"), at the prices and during the
periods as hereinafter specified, up to three hundred and ten thousand (310,000)
Units ("Units"), each Unit consisting of one share of the Company's Common
Stock, $.01 par value, as now constituted ("Common Stock") and one warrant
("Warrants"). Each Warrant is exercisable to purchase one share of Common Stock
at an exercise price of $_______, subject to adjustment, at any time commencing
one year from the effective date of the Registration Statement (as defined
below), but not earlier than the Separation Date (as defined in the Warrant
Agreement) until _______ , 2002.

     The Units have been registered under a Registration Statement on Form S-1,
(File No. 333-_______ ) declared effective by the Securities and Exchange
Commission on _______ (the "Registration Statement"). This Option, together with
options of like tenor, constituting in the aggregate options (the "Options") to
purchase 310,000 Units, subject to adjustment in accordance with Section 8 of
this Option (the "Option Units"), was originally issued pursuant to an
underwriting agreement between the Company and Royce Investment Group, Inc., as
representative of the Underwriters named in Schedule A thereto (the
"Underwriters"), in connection with a public offering (the "Offering") of
3,100,000 Units (the "Public Units") through the Underwriters, in consideration
of $310 received for the Options.

     Except as specifically otherwise provided herein, the Common Stock and the
Warrants issued pursuant to the option herein granted (the "Option") shall bear
the same terms and conditions as described under the caption "Description of
Securities" in the Registration Statement, and the Warrants shall be governed by
the terms of the Warrant Agreement dated as of __________, 1997 executed in
connection with such public offering (the "Warrant Agreement"), and except that
(i) the holder shall have registration rights under the Securities Act of 1933,
as amended (the "Act"), for the Option, the Common Stock and the Warrants
included in the Option Units, and the shares of Common Stock underlying the
Warrants, as more fully described in Section 6 of this Option and (ii) the
Warrants issuable upon exercise of the Option will be subject to redemption by
the Company pursuant to the Warrant Agreement at any time after the Option has
been exercised and the Warrants underlying the Option Units are outstanding. Any
such redemption shall be on the same terms and conditions as the Warrants
included in the Public Units (the "Public Warrants"). The Company will list the
Common Stock underlying this Option and, at the Holder's request the Warrants,
on the Nasdaq National Market,

                                                                              

<PAGE>



the Nasdaq Small Cap Market or such other exchange or market as the Common Stock
or Public Warrants may then be listed or quoted. In the event of any extension
of the expiration date or reduction of the exercise price of the Public
Warrants, the same changes to the Warrants included in the Option Units shall be
simultaneously effected.

     1. The rights represented by this Option shall be exercised at the prices,
subject to adjustment in accordance with Section 8 of this Option ("the
"Exercise Price"), and during the periods as follows:

          (a) During the period from _________, 1997 to _________, 1998,
     inclusive, the Holder shall have no right to purchase any Option Units
     hereunder, except that in the event of any merger, consolidation or sale of
     all or substantially all the capital stock or assets of the Company or in
     the case of any statutory exchange of securities with another corporation
     (including any exchange effected in connection with a merger of another
     corporation into the Company) subsequent to _________, 1997, the Holder
     shall have the right to exercise this Option and the Warrants included
     herein at such time and receive the kind and amount of shares of stock and
     other securities and property (including cash) which a holder of the number
     of shares of Common Stock underlying this Option and the Warrants included
     in this Option would have owned or been entitled to receive had this Option
     been exercised immediately prior thereto.

          (b) Between _________, 1998, and _________, 2002 inclusive, the Holder
     shall have the option to purchase Option Units hereunder at a price of
     $_______ per Unit. For purposes of the adjustments under Section 8 hereof,
     the Per Share Exercise Price shall be deemed to be $_______, subject to
     further adjustment as provided in such Section 8.

          (c) After _________, 2002 the Holder shall have no right to purchase
     any Units hereunder.

     2. (a) The rights represented by this Option may be exercised at any time
within the period above specified, in whole or in part, by (i) the surrender of
this Option (with the purchase form at the end hereof properly executed) at the
principal executive office of the Company (or such other office or agency of the
Company as it may designate by notice in writing to the Holder at the address of
the Holder appearing on the books of the Company); and (ii) payment to the
Company of the exercise price then in effect for the number of Option Units
specified in the above-mentioned purchase form together with applicable stock
transfer taxes, if any. This Option shall be deemed to have been exercised, in
whole or in part to the extent specified, immediately prior to the close of
business on the date this Option is surrendered and payment is made in
accordance with the foregoing provisions of this Section 2, and the person or
persons in whose name or names the certificates for shares of Common Stock and
Warrants shall



                                       -2-

<PAGE>



be issuable upon such exercise shall become the holder or holders of record of
such Common Stock and Warrants at that time and date. The certificates for the
Common Stock and Warrants so purchased shall be delivered to the Holder as soon
as practicable but not later than ten (10) days after the rights represented by
this Option shall have been so exercised.

     (b) At any time during the period above specified, during which this Option
may be exercised, the Holder may, at its option, exchange this Option, in whole
or in part (an "Option Exchange"), into the number of Option Units determined in
accordance with this Section (b), by surrendering this Option at the principal
office of the Company or at the office of its stock transfer agent, accompanied
by a notice stating such Holder's intent to effect such exchange, the number of
Option Units into which this Option is to be exchanged and the date on which the
Holder requests that such Option Exchange occur (the "Notice of Exchange"). The
Option Exchange shall take place on the date specified in the Notice of Exchange
or, if later, the date the Notice of Exchange is received by the Company (the
"Exchange Date"). Certificates for the shares of Common Stock and Warrants
issuable upon such Option Exchange and, if applicable, a new Option of like
tenor evidencing the balance of the Option Units remaining subject to this
Option, shall be issued as of the Exchange Date and delivered to the Holder
within seven (7) days following the Exchange Date. In connection with any Option
Exchange, this Option shall represent the right to subscribe for and acquire the
number of Option Units (rounded to the next highest integer) equal to (x) the
number of Option Units specified by the Holder in its Notice of Exchange up to
the maximum number of Option Units subject to this option (the "Total Number")
less (y) the number of Option Units equal to the quotient obtained by dividing
(A) the product of the Total Number and the existing Exercise Price by (B) the
Fair Market Value. "Fair Market Value" shall mean first, if there is a trading
market as indicated in Subsection (i) below for the Units, such Fair Market
Value of the Units and if there is no such trading market in the Units, then
Fair Market Value shall have the meaning indicated in Subsections (ii) through
(v) below for the aggregate value of all shares of Common Stock and Warrants
which comprise a Unit:

          (i) If the Units are listed on a national securities exchange or
     listed or admitted to unlisted trading privileges on such exchange or
     listed for trading on the Nasdaq National Market or the Nasdaq Small Cap
     Market, the Fair Market Value shall be the average of the last reported
     sale prices or the average of the means of the last reported bid and asked
     prices, respectively, of the Units on such exchange or market for the
     twenty (20) business days ending on the last business day prior to the
     Exchange Date; or

          (ii) If the Common Stock or Warrants are listed on a national
     securities exchange or admitted to unlisted trading privileges on such
     exchange or listed for trading on the Nasdaq National Market or the Nasdaq
     Small Cap Market, the Fair Market Value shall be the average of the last
     reported sale prices or the average of the means of the last reported bid
     and asked prices, respectively, of Common Stock or Warrants, respectively,
     on such exchange or market for the twenty (20) business days ending on the
     last business day prior to the Exchange Date; or

                                       -3-

<PAGE>



          (iii) If the Common Stock or Warrants are not so listed or admitted to
     unlisted trading privileges, the Fair Market Value shall be the average of
     the means of the last reported bid and asked prices of the Common Stock or
     Warrants, respectively, for the twenty (20) business days ending on the
     last business day prior to the Exchange Date; or

          (iv) If the Common Stock is not so listed or admitted to unlisted
     trading privileges and bid and asked prices are not so reported, the Fair
     Market Value shall be an amount, not less than book value thereof as at the
     end of the most recent fiscal year of the Company ending prior to the
     Exchange Date, determined in such reasonable manner as may be prescribed by
     the Board of Directors of the Company; or

          (v) If the Warrants are not so listed or admitted to unlisted trading
     privileges, and bid and asked prices are not so reported for Warrants, then
     Fair Market Value for the Warrants shall be an amount equal to the
     difference between (i) the Fair Market Value of the shares of Common Stock
     and Warrants which may be received upon the exercise of the Warrants, as
     determined herein, and (ii) the Warrant Exercise Price.

     3. Neither this Option nor the underlying securities shall be transferred,
sold, assigned, or hypothecated for a period of one year commencing on the
effective date of the Registration Statement except that they may be transferred
to successors of the Holder, and may be assigned in whole or in part to any
person who is an officer of the Holder, any member participating in the selling
group relating to the Offering or any officer of such selling group member. Any
such assignment shall be effected by the Holder (i) executing the form of
assignment at the end hereof and (ii) surrendering this Option for cancellation
at the office or agency of the Company referred to in Section 2 hereof,
accompanied by a certificate (signed by an officer of the Holder if the Holder
is a corporation), stating that each transferee is a permitted transferee under
this Section 3 hereof; whereupon the Company shall issue, in the name or names
specified by the Holder (including the Holder) a new Option or Options of like
tenor and representing in the aggregate rights to purchase the same number of
Option Units as are purchasable hereunder.

     4. The Company covenants and agrees that all shares of Common Stock which
may be issued as part of the Option Units purchased hereunder and the Common
Stock which may be issued upon exercise of the Warrants will, upon issuance, be
duly and validly issued, fully paid and nonassessable and no personal liability
will attach to the holder thereof. The Company further covenants and agrees that
during the periods within which this Option may be exercised, the Company will
at all times have authorized and reserved a sufficient number of shares of its
Common Stock to provide for the exercise of this Option and that it will have
authorized and reserved a sufficient number of shares of Common Stock for
issuance upon exercise of the Warrants included in the Option Units.


                                                                        

                                       -4-

<PAGE>



     5. This Option shall not entitle the Holder to any voting rights or any
other rights, or subject to the Holder to any liabilities, as a stockholder of
the Company.

     6. (a) The Company shall advise the Holder or its transferee, whether the
Holder holds the Option or has exercised the Option and holds Option Units or
any of the securities underlying the Option Units, by written notice at least
four weeks prior to the filing of any post-effective amendment to the
Registration Statement or of any new registration statement or post-effective
amendment thereto under the Act covering any securities of the Company, for its
own account or for the account of others, and will for a period of seven years
from the effective date of the Registration Statement, upon the request of the
Holder, include in any such post-effective amendment or registration statement,
such information as may be required to permit a public offering of the Option,
all or any of the Option Units, the Common Stock or Warrants included in the
Option Units or the Common Stock issuable upon the exercise of the Warrants (the
"Registrable Securities").

     (b) If any 50% holder (as defined below) shall give notice to the Company
at any time to the effect that such holder desires to register under the Act
this Option, the Option Units or any of the underlying securities contained in
the Option Units under such circumstances that a public distribution (within the
meaning of the Act) of any such securities will be involved then the Company
will promptly, but no later than two weeks after receipt of such notice, file a
post-effective amendment to the current Registration Statement or a new
registration statement on Form S-1 or such other form as the holder requests
pursuant to the Act, to the end that the Option, the Option Units and/or any of
the securities underlying the Option Units may be publicly sold under the Act as
promptly as practicable thereafter and the Company will use its best efforts to
cause such registration to become and remain effective (including the taking of
such steps as are necessary to obtain the removal of any stop order); provided,
that such holder shall furnish the Company with appropriate information in
connection therewith as the Company may reasonably request in writing. The 50%
holder may, at its option, request the filing of a post-effective amendment to
the current Registration Statement or a new registration statement under the Act
on one occasion during the four year period beginning one year from the
effective date of the Registration Statement. The Holder may, at its option
request the registration of the Option and/or any of the securities underlying
the Option in a registration statement made by the Company as contemplated by
Section 6(a) or in connection with a request made pursuant to this Section 6(b)
prior to acquisition of the Option Units issuable upon exercise of the Option
and even though the Holder has not given notice of exercise of the Option. The
50% holder may, at its option, request such post-effective amendment or new
registration statement during the described period with respect to the Option,
the Option Units as a unit, or separately as to the Common Stock and/or Warrants
included in the Option Units and/or the Common Stock issuable upon the exercise
of the Warrants, and such registration rights may be exercised by the 50% holder
prior to or subsequent to the exercise of the Option.

     Within ten days after receiving any such notice pursuant to this Section
6(b), the Company shall give notice to the other holders of the Options,
advising that the Company is proceeding with such post-effective amendment or
registration statement and offering to include

                                                                        

                                       -5-

<PAGE>



therein the securities underlying the Options of the other holders, provided
that they shall furnish the Company with such appropriate information (relating
to the intentions of such holders) in connection therewith as the Company shall
reasonably request in writing. All costs and expenses of the first such
post-effective amendment or new registration statement under this paragraph 6(b)
shall be borne by the Company, except that the holders shall bear the fees of
their own counsel and any underwriting discounts or commissions applicable to
any of the securities sold by them. If the Company determines to include
securities to be sold by it in any registration statement originally requested
pursuant to this Section 6(b), such registration shall instead be deemed to have
been a registration under Section 6(a) and not under this Section 6(b).

     The Company will maintain such registration statement or post-effective
amendment current under the Act for a period of at least six months (and for up
to an additional three months if requested by the Holder) from the effective
date thereof.

     (c) The term "50% holder" as used in this Section 6 shall mean the holder
of at least 50% of the Common Stock and the Warrants underlying the Options
(considered in the aggregate) and shall include any owner or combination of
owners of such securities, which ownership shall be calculated by determining
the number of shares of Common Stock held by such owner or owners as well as the
number of shares then issuable upon exercise of the Warrants.

     (d) Whenever pursuant to Section 6 a registration statement relating to any
Registrable Securities is filed under the Act, amended or supplemented, the
Company shall (i) supply prospectuses and such other documents as the Holder may
request in order to facilitate the public sale or other disposition of the
Registrable Securities, (ii) use its best efforts to register and qualify any of
the Registrable Securities for sale in such states as such Holder designates,
(iii) furnish indemnification in the manner provided in Section 7 hereof, (iv)
notify each Holder of Registrable Securities at any time when a prospectus
relating thereto is required to be delivered under the Securities Act, of the
happening of any event as a result of which the prospectus included in such
registration statement, as then in effect, contains an untrue statement of a
material fact or omits to state a material fact required to be stated therein or
necessary to make the statements therein not misleading and, at the request of
any such Holder, prepare and furnish to such Holder a reasonable number of
copies of a supplement to or an amendment of such prospectus as may be necessary
so that, as thereafter delivered to the purchasers of such Registrable
Securities, such prospectus shall not included an untrue statement of a material
fact or omit to state material fact required to be stated therein or necessary
to make the statements therein not misleading and (v) do any and all other acts
and things which may be necessary or desirable to enable such Holders to
consummate the public sale or other disposition of the Registrable Securities,
The Holder shall furnish appropriate information in connection therewith and
indemnification as set forth in Section 7.

     (e) The Company shall not permit the inclusion of any securities other than
the Registrable Securities to be included in any registration statement filed
pursuant to Section 6(b) hereof without the prior written consent of the 50%
holder.

                                                                             

                                       -6-

     (f) The Company shall furnish to each Holder participating in the offering
and to each underwriter, if any, a signed counterpart, addressed to such Holder
or underwriter, of (i) an opinion of counsel to the Company, dated the effective
date of such registration statement (or, if such registration includes an
underwritten public offering, an opinion dated the date of the closing under the
underwriting agreement), and (ii) if such registration includes an underwritten
public offering, a "cold comfort" letter dated the effective date of such
registration statement and dated the date of the closing under the underwriting
agreement signed by the independent public accountants who have issued a report
on the Company's financial statements included in such registration statement,
in each case covering substantially the same matters with respect to such
registration statement (and the prospectus included therein) and, in the case of
such accountants' letter, with respect to events subsequent to the date of such
financial statements, as are customarily covered in opinions of issuer's counsel
and in accountants' letters delivered to underwriters in underwritten public
offerings of securities.

     (g) The Company shall deliver promptly to each Holder participating in the
offering requesting the correspondence and memoranda described below and to the
managing underwriter copies of all correspondence between the Commission and the
Company, its counsel or auditors and all memoranda relating to discussions with
the Commission or its staff with respect to the registration statement and
permit each Holder and underwriter to do such investigation, upon reasonable
advance notice, with respect to information contained in or omitted from the
registration statement as it deems reasonable necessary to comply with
applicable securities laws or rules of the National Association of Securities
Dealers, Inc. ("NASD"). Such investigation shall include access to
non-confidential books, records and properties and opportunities to discuss the
business of the Company with its officers and independent auditors, all to such
reasonable extent and at such reasonable times as any such Holder shall
reasonably request.

     7. (a) Whenever pursuant to Section 6 a registration statement relating to
the Registrable Securities is filed under the Act, amended or supplemented, the
Company will indemnify and hold harmless each holder of the Registrable
Securities covered by such registration statement, amendment or supplement (such
holder being hereinafter called the "Distributing Holder"), and each person, if
any, who controls (within the meaning of the Act) the Distributing Holder, and
each underwriter (within the meaning of the Act) of such securities and each
person, if any, who controls (within the meaning of the Act) any such
underwriter, against any losses, claims, damages or liabilities, joint or
several, to which the Distributing Holder, any such controlling person or any
such underwriter may become subject, under the Act or otherwise, insofar as such
losses, claims, damages or liabilities (or actions in respect thereof) arise out
of or are based upon any untrue statement or alleged untrue statement of any
material fact contained in any such registration statement or any preliminary
prospectus or final prospectus constituting a part thereof or any amendment or
supplement thereto, or arise out of or are based upon the omission to state
therein a material fact required to be stated therein or necessary to make the
statements therein not misleading; and will reimburse the Distributing Holder
and each such controlling person and underwriter for any legal or other expenses

                                                                     

                                       -7-

<PAGE>



reasonably incurred by the Distributing Holder or such controlling person or
underwriter in connection with investigating or defending any such loss, claim,
damage, liability or action; provided, however, that the Company will not be
liable in any such case to the extent that any such loss, claim, damage or
liability arises out of or is based upon an untrue statement or alleged untrue
statement or omission or alleged omission made in said registration statement,
said preliminary prospectus, said final prospectus or said amendment or
supplement in reliance upon and in conformity with written information furnished
by such Distributing Holder specifically for use in the preparation thereof.

     (b) If requested by the Company prior to the filing of any registration
statement covering the Registrable Securities, each Distributing Holder will
agree, severally but not jointly, to indemnify and hold harmless the Company
against any losses, claims, damages or liabilities to which the Company may
become subject, under the Act or otherwise, insofar as such losses, claims,
damages or liabilities arise out of or are based upon any untrue or alleged
untrue statement of any material fact contained in said registration statement,
said preliminary prospectus, said final prospectus, or said amendment or
supplement, or arise out of or are based upon the omission or the alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, in each case to the
extent, but only to the extent that such untrue statement or alleged untrue
statement or omission or alleged omission was made in said registration
statement, said preliminary prospectus, said final prospectus or said amendment
or supplement in reliance upon and in conformity with written information
furnished by such Distributing Holder specifically for use in the preparation
thereof; except that the maximum amount which may be recovered from the
Distributing Holder pursuant to this Section 7 or otherwise shall be limited to
the amount of net proceeds received by the Distributing Holder from the sale of
the Registrable Securities.

     (c) Promptly after receipt by an indemnified party under this Section 7 of
notice of the commencement of any action, such indemnified party will, if a
claim in respect thereof is to be made against any indemnifying party, give the
indemnifying party notice of the commencement thereof; but the omission so to
notify the indemnifying party will not relieve it from any liability which it
may have to any indemnified party otherwise than under this Section 7.

     (d) In case any such action is brought against any indemnified party, and
it notifies an indemnifying party of the commencement thereof, the indemnifying
party will be entitled to participate in, and, to the extent that it may wish,
jointly with any other indemnifying party similarly notified to assume the
defense thereof, with counsel reasonably satisfactory to such indemnified party,
and after notice from the indemnifying party to such indemnified party of its
election so to assume the defense thereof, the indemnifying party will not be
liable to such indemnified party under this Section 7 for any legal or other
expenses subsequently incurred by such indemnified party in connection with the
defense thereof other than reasonable costs of investigation.


                                                                       

                                       -8-

<PAGE>



     (8) In addition to the provisions of Section 1(a) of this Option, the
Exercise Price in effect at any time and the number and kind of securities
purchasable upon the exercise of the Options shall be subject to adjustment from
time to time upon the happening of certain events as follows:

          (a) In case the Company shall (i) declare a dividend or make a
     distribution on its outstanding shares of Common Stock in shares of Common
     Stock, (ii) subdivide or reclassify its outstanding shares of Common Stock
     into a greater number of shares, or (iii) combine or reclassify its
     outstanding shares of Common Stock into a smaller number of shares, the
     Exercise Price in effect at the time of the record date for such dividend
     or distribution or of the effective date of such subdivision, combination
     or reclassification shall be adjusted so that it shall equal the price
     determined by multiplying the Exercise Price by a fraction, the denominator
     of which shall be the number of shares of Common Stock outstanding after
     giving effect to such action, and the numerator of which shall be the
     number of shares of Common Stock outstanding immediately prior to such
     action. Such adjustment shall be made successively whenever any event
     listed above shall occur.

          (b) Whenever the Exercise Price payable upon exercise of each Option
     is adjusted pursuant to Subsection (a) above, (i) the number of shares of
     Common Stock included in an Option Unit shall simultaneously be adjusted by
     multiplying the number of shares of Common Stock included in Option Unit
     immediately prior to such adjustment by the Exercise Price in effect
     immediately prior to such adjustment and dividing the product so obtained
     by the Exercise Price, as adjusted and (ii) the number of shares of Common
     Stock or other securities issuable upon exercise of the Warrants included
     in the Option Units and the exercise price of such Warrants shall be
     adjusted in accordance with the applicable terms of the Warrant Agreement.

          (c) No adjustment in the Exercise Price shall be required unless such
     adjustment would require an increase or decrease of at least five cents
     ($0.05) in such price; provided, however, that any adjustments which by
     reason of this Subsection (c)(i) are not required to be made shall be
     carried forward and taken into account in any subsequent adjustment
     required to be made hereunder. All calculations under this Section 8 shall
     be made to the nearest cent or to the nearest one-hundredth of a share, as
     the case may be. Anything in this Section 8 to the contrary
     notwithstanding, the Company shall be entitled, but shall not be required,
     to make such changes in the Exercise Price, in addition to those required
     by this Section 8, as it shall determine, in its sole discretion, to be
     advisable in order that any dividend or distribution in shares of Common
     Stock, or any subdivision, reclassification or combination of Common Stock,
     hereafter made by the Company shall not result in any Federal Income tax
     liability to the holders of

                                       
                                       -9-

<PAGE>



     Common Stock or securities convertible into Common Stock (including
     Warrants issuable upon exercise of this Option).

          (d) Whenever the Exercise Price is adjusted, as herein provided, the
     Company shall promptly but no later than 10 days after any request for such
     an adjustment by the Holder, cause a notice setting forth the adjusted
     Exercise Price and adjusted number of Option Units issuable upon exercise
     of each Option and, if requested, information describing the transactions
     giving rise to such adjustments, to be mailed to the Holders, at the
     address set forth herein, and shall cause a certified copy thereof to be
     mailed to its transfer agent, if any. The Company may retain a firm of
     independent certified public accountants selected by the Board of Directors
     (who may be the regular accountants employed by the Company) to make any
     computation required by this Section 8, and a certificate signed by such
     firm shall be conclusive evidence of the correctness of such adjustment.

          (e) In the event that at any time, as a result of an adjustment made
     pursuant to Subsection (a) above, the Holder of this Option thereafter
     shall become entitled to receive any shares of the Company, other than
     Common Stock, thereafter the number of such other shares so receivable upon
     exercise of this Option shall be subject to adjustment from time to time in
     a manner and on terms as nearly equivalent as practicable to the provisions
     with respect to the Common Stock contained in Subsections (a) to (d),
     inclusive above.

          (f) In case any event shall occur as to which the other provisions of
     this Section 8 or Section 1(a) hereof are not strictly applicable but as to
     which the failure to make any adjustment would not fairly protect the
     purchase rights represented by this Option in accordance with the essential
     intent and principles hereof then, in each such case, the Holders of
     Options representing the right to purchase a majority of the Option Units
     may appoint a firm of independent public accountants reasonably acceptable
     to the Company, which shall give their opinion as to the adjustment, if
     any, on a basis consistent with the essential intent and principles
     established herein, necessary to preserve the purchase rights represented
     by the Options. Upon receipt of such opinion, the Company will promptly
     mail a copy thereof to the Holder of this Option and shall make the
     adjustments described therein. The fees and expenses of such independent
     public accountants shall be borne by the Company.

     9. This Agreement shall be governed by and in accordance with the laws of
the State of New York, without giving effect to the principles of conflicts of
law thereof.

               Warrant to Purchase 210,000 Shares of Common Stock.



                        WARRANT TO PURCHASE COMMON STOCK

                                       OF

                               IAT HOLDINGS, INC.



     This is to Certify That, FOR VALUE RECEIVED, K.-D. Sippel
or assigns ("Holder"), is entitled to purchase from IAT Holdings, Inc., a
Delaware corporation (the "Company"), following an initial public offering (the
"IPO") of shares of common stock, par value $.01 per share (the "Common Stock")
of the Company and subject to the provisions of this Warrant, 210,000 fully
paid, validly issued and nonassessable shares of Common Stock of the Company at
a price per share equal to 130% of the initial public offering price of a share
of Common Stock in the IPO at any time or from time to time during the ten (10)
year period following the closing date of the IPO, but not later than 5:00 p.m.
New York City Time on December 31, 2006. The number of shares of Common Stock to
be received upon the exercise of this Warrant and the price to be paid for each
share of Common Stock may be adjusted from time to time as hereinafter set
forth. The shares of Common Stock deliverable upon such exercise, and as
adjusted from time to time, are hereinafter sometimes referred to as "Warrant
Shares" and the exercise price of a share of Common Stock in effect at any time
and as adjusted from time to time is hereinafter sometimes referred to as the
"Exercise Price."

     (a) EXERCISE OF WARRANT.

          (1) This Warrant may be exercised in whole or in part at any time or
     from time to time during the ten (10) year period following the closing
     date of the IPO, but not later than 5:00 New York City Time on December 31,
     2006 (the "Exercise Period") provided, however, that (i) if either such day
     is a day on which banking institutions in the State of New York are
     authorized by law to close, then on the next succeeding day which shall not
     be such a day, and (ii) in the event of any merger, consolidation or sale
     of substantially all the assets of the Company as an entirety, resulting in
     any distribution to the Company's stockholders, prior to December 31, 2006,
     the Holder shall have the right to exercise this Warrant commencing at such
     time through December 31, 2006 into the kind and amount of shares of stock
     and other securities and property (including cash) receivable by a holder
     of the number of shares of Common Stock into which this Warrant might have





                                       -1-

<PAGE>



     been exercisable immediately prior thereto. This Warrant may be exercised
     by presentation and surrender hereof to the Company at its principal
     office, or at the office of its stock transfer agent, if any, with the
     Purchase Form annexed hereto duly executed and accompanied by payment of
     the Exercise Price for the number of Warrant Shares specified in such form.
     As soon as practicable after each such exercise of the warrants, but not
     later than seven (7) days from the date of such exercise, the Company shall
     issue and deliver to the Holder a certificate or certificate for the
     Warrant Shares issuable upon such exercise, registered in the name of the
     Holder or its designee. If this Warrant should be exercised in part only,
     the Company shall, upon surrender of this Warrant for cancellation, execute
     and deliver a new Warrant evidencing the rights of the Holder thereof to
     purchase the balance of the Warrant Shares purchasable thereunder. Upon
     receipt by the Company of this Warrant at its office, or by the stock
     transfer agent of the Company at its office, in proper form for exercise,
     the Holder shall be deemed to be the holder of record of the shares of
     Common Stock issuable upon such exercise, notwithstanding that the stock
     transfer books of the Company shall then be closed or that certificates
     representing such shares of Common Stock shall not then be physically
     delivered to the Holder.

          (2) At any time during the Exercise Period, the Holder may, at its
     option, exchange this Warrant, in whole or in part (a "Warrant Exchange"),
     into the number of Warrant Shares determined in accordance with this
     Section (a)(2), by surrendering this Warrant at the principal office of the
     Company or at the office of its stock transfer agent, accompanied by a
     notice stating such Holder's intent to effect such exchange, the number of
     Warrant Shares to be exchanged and the date on which the Holder requests
     that such Warrant Exchange occur (the "Notice of Exchange"). The Warrant
     Exchange shall take place on the date specified in the Notice of Exchange
     or, if later, the date the Notice of Exchange is received by the Company
     (the "Exchange Date"). Certificates for the shares issuable upon such
     Warrant Exchange and, if applicable, a new warrant of like tenor evidencing
     the balance of the shares remaining subject to this Warrant, shall be
     issued as of the Exchange Date and delivered to the Holder within seven (7)
     days following the Exchange Date. In connection with any Warrant Exchange,
     this Warrant shall represent the right to subscribe for and acquire the
     number of Warrant Shares (rounded to the next highest integer) equal to (i)
     the number of Warrant Shares specified by the Holder in its Notice of
     Exchange (the "Total Number") less (ii) the number of Warrant Shares equal
     to the quotient obtained by dividing (A) the product of the Total Number
     and the existing Exercise Price by (B) the current market value of a share
     of Common Stock. Current market value shall have the meaning set forth
     Section (c) below, except that for purposes hereof, the date of exercise,
     as used in such Section (c), shall mean the Exchange Date.

     (b) RESERVATION OF SHARES. The Company shall at all times reserve for
issuance and/or delivery upon exercise of this Warrant such number of shares of
its Common Stock as shall be required for issuance and delivery upon exercise of
the Warrants.

     (c) FRACTIONAL SHARES. No fractional shares or script representing
fractional shares shall be issued upon the exercise of this Warrant. With
respect to any fraction of





                                       -2-

<PAGE>



a share called for upon any exercise hereof, the Company shall pay to the Holder
an amount in cash equal to such fraction multiplied by the current market value
of a share, determined as follows:

          (1) If the Common Stock is listed on a national securities exchange or
     admitted to unlisted trading privileges on such exchange or listed for
     trading on the Nasdaq National Market, the current market value shall be
     the last reported sale price of the Common Stock on such exchange or market
     on the last business day prior to the date of exercise of this Warrant or
     if no such sale is made on such day, the average closing bid and asked
     prices for such day on such exchange or market; or

          (2) If the Common Stock is not so listed or admitted to unlisted
     trading privileges, but is traded on the Nasdaq Small Cap Market, the
     current Market Value shall be the average of the closing bid and asked
     prices for such day on such market and if the Common Stock is not so
     traded, the current market value shall be the mean of the last reported bid
     and asked prices reported by the National Quotation Bureau, Inc. on the
     last business day prior to the date of the exercise of this Warrant; or

          (3) If the Common Stock is not so listed or admitted to unlisted
     trading privileges and bid and asked prices are not so reported, the
     current market value shall be an amount, not less than book value thereof
     as at the end of the most recent fiscal year of the Company ending prior to
     the date of the exercise of the Warrant, determined in such reasonable
     manner as may be prescribed by the Board of Directors of the Company.

     (d) EXCHANGE, TRANSFER, ASSIGNMENT OR LOSS OF WARRANT. This Warrant is
exchangeable, without expense, at the option of the Holder, upon presentation
and surrender hereof to the Company or at the office of its stock transfer
agent, if any, for other warrants of different denominations entitling the
holder thereof to purchase in the aggregate the same number of shares of Common
Stock purchasable hereunder. Upon surrender of this Warrant to the Company at
its principal office or at the office of its stock transfer agent, if any, with
the Assignment Form annexed hereto duly executed and funds sufficient to pay any
transfer tax, the Company shall, without charge, execute and deliver a new
Warrant in the name of the assignee named in such instrument of assignment and
this Warrant shall promptly be cancelled. This Warrant may be divided or
combined with other warrants which carry the same rights upon presentation
hereof at the principal office of the Company or at the office of its stock
transfer agent, if any, together with a written notice specifying the names and
denominations in which new Warrants are to be issued and signed by the Holder
hereof. The term "Warrant" as used herein includes any Warrants into which this
Warrant may be divided or exchanged. Upon receipt by the Company of evidence
satisfactory to it of the loss, theft, destruction or mutilation of this
Warrant, and (in the case of loss, theft or destruction) of reasonably
satisfactory indemnification, and upon surrender and cancellation of this
Warrant, if mutilated, the Company will execute and deliver a new Warrant of
like tenor and date. Any such new Warrant





                                       -3-

<PAGE>



executed and delivered shall constitute an additional contractual obligation on
the part of the Company, whether or not this Warrant so lost, stolen, destroyed,
or mutilated shall be at any time enforceable by anyone.

     (e) RIGHTS OF THE HOLDER. The Holder shall not, by virtue hereof, be
entitled to any rights of a shareholder in the Company, either at law or equity,
and the rights of the Holder are limited to those expressed in the Warrant and
are not enforceable against the Company except to the extent set forth herein.

     (f) ANTI-DILUTION PROVISIONS. The Exercise Price in effect at any time and
the number and kind of securities purchasable upon the exercise of the Warrants
shall be subject to adjustment from time to time upon the happening of certain
events as follows:

          (1) In case the Company shall (i) declare a dividend or make a
     distribution on its outstanding shares of Common Stock in shares of Common
     Stock, (ii) subdivide or reclassify its outstanding shares of Common Stock
     into a greater number of shares, or (iii) combine or reclassify its
     outstanding shares of Common Stock into a smaller number of shares, the
     Exercise Price in effect at the time of the record date for such dividend
     or distribution or of the effective date of such subdivision, combination
     or reclassification shall be adjusted so that it shall equal the price
     determined by multiplying the Exercise Price by a fraction, the denominator
     of which shall be the number of shares of Common Stock outstanding after
     giving effect to such action, and the numerator of which shall be the
     number of shares of Common Stock outstanding immediately prior to such
     action. Such adjustment shall be made successively whenever any event
     listed above shall occur.

          (2) In case the Company shall fix a record date for the issuance of
     rights or warrants to all holders of its Common Stock entitling them to
     subscribe for or purchase shares of Common Stock (or securities convertible
     into Common Stock) at a price (the "Subscription Price") (or having a
     conversion price per share) less than the current market price of the
     Common Stock (as defined in Subsection (8) below) on the record date
     mentioned below, or less than the Exercise Price on such record date, the
     Exercise Price shall be adjusted so that the same shall equal the lower of
     (i) the price determined by multiplying the Exercise Price in effect
     immediately prior to the date of such issuance by a fraction, the numerator
     of which shall be the sum of the number of shares of Common Stock
     outstanding on the record date mentioned below and the number of additional
     shares of Common Stock which the aggregate offering price of the total
     number of shares of Common Stock so offered (or the aggregate conversion
     price of the convertible securities so offered) would purchase at such
     current market price per share of the Common Stock, and the denominator of
     which shall be the sum of the number of shares of Common Stock outstanding
     on such





                                       -4-

<PAGE>



     record date and the number of additional shares of Common Stock offered for
     subscription or purchase (or into which the convertible securities so
     offered are convertible) or (ii) in the event the Subscription Price is
     equal to or higher than the current market price but is less than the
     Exercise Price, the price determined by multiplying the Exercise Price in
     effect immediately prior to the date of issuance by a fraction, the
     numerator of which shall be the sum of the number of shares outstanding on
     the record date mentioned below and the number of additional shares of
     Common Stock which the aggregate offering price of the total number of
     shares of Common Stock so offered (or the aggregate conversion price of the
     convertible securities so offered) would purchase at the Exercise Price in
     effect immediately prior to the date of such issuance, and the denominator
     of which shall be the sum of the number of shares of Common Stock
     outstanding on the record date mentioned below and the number of additional
     shares of Common Stock offered for subscription or purchase (or into which
     the convertible securities so offered are convertible). Such adjustment
     shall be made successively whenever such rights or warrants are issued and
     shall become effective immediately after the record date for the
     determination of shareholders entitled to receive such rights or warrants;
     and to the extent that shares of Common Stock are not delivered (or
     securities convertible into Common Stock are not delivered) after the
     expiration of such rights or warrants the Exercise Price shall be
     readjusted to the Exercise Price which would then be in effect had the
     adjustments made upon the issuance of such rights or warrants been made
     upon the basis of delivery of only the number of shares of Common Stock (or
     securities convertible into Common Stock) actually delivered.

          (3) In case the Company shall hereafter distribute to the holders of
     its Common Stock evidences of its indebtedness or assets (excluding cash
     dividends or distributions and dividends or distributions referred to in
     Subsection (1) above) or subscription rights or warrants (excluding those
     referred to in Subsection (2) above), then in each such case the Exercise
     Price in effect thereafter shall be determined by multiplying the Exercise
     Price in effect immediately prior thereto by a fraction, the numerator of
     which shall be the total number of shares of Common Stock outstanding
     multiplied by the current market price per share of Common Stock (as
     defined in Subsection (8) below), less the fair market value (as determined
     by the Company's Board of Directors) of said assets or evidences of
     indebtedness so distributed or of such rights or warrants, and the
     denominator of which shall be the total number of shares of Common Stock
     outstanding multiplied by such current market price per share of Common
     Stock. Such adjustment shall be made successively whenever such a record
     date is fixed. Such adjustment shall be made whenever any such distribution
     is made and shall become effective immediately after the record date for
     the determination of shareholders entitled to receive such distribution.






                                       -5-

<PAGE>



          (4) In case the Company shall issue shares of its Common Stock,
     excluding shares issued (i) in any of the transactions described in
     Subsection (1) above, (ii) upon exercise of options granted to the
     Company's employees under a plan or plans adopted by the Company's Board of
     Directors and approved by its shareholders, if such shares would otherwise
     be included in this Subsection (4), (but only to the extent that the
     aggregate number of shares excluded hereby and issued after the date
     hereof, shall not exceed 5% of the Company's Common Stock outstanding at
     the time of any issuance), (iii) upon exercise of this Warrant (iv) to
     shareholders of any corporation which merges into the Company in proportion
     to their stock holdings of such corporation immediately prior to such
     merger, upon such merger, or (v) issued in a bona fide public offering
     pursuant to a firm commitment underwriting, but only if no adjustment is
     required pursuant to any other specific subsection of this Section (f)
     (without regard to Subsection (9) below) with respect to the transaction
     giving rise to such rights, for a consideration per share (the "Offering
     Price") less than the current market price per share (as defined in
     Subsection (8) below) on the date the Company fixes the offering price of
     such additional shares or less than the Exercise Price, the Exercise Price
     shall be adjusted immediately thereafter so that it shall equal the lower
     of (i) the price determined by multiplying the Exercise Price in effect
     immediately prior thereto by a fraction, the numerator of which shall be
     the sum of the number of shares of Common Stock outstanding immediately
     prior to the issuance of such additional shares and the number of shares of
     Common Stock which the aggregate consideration received (determined as
     provided in Subsection (7) below) for the issuance of such additional
     shares would purchase at such current market price per share of Common
     Stock, and the denominator of which shall be the number of shares of Common
     Stock outstanding immediately after the issuance of such additional shares
     or (ii) in the event the Offering Price is equal to or higher than the
     current market price per share but less than the Exercise Price, the price
     determined by multiplying the Exercise Price in effect immediately prior to
     the date of issuance by a fraction, the numerator of which shall be the
     number of shares of Common Stock outstanding immediately prior to the
     issuance of such additional shares and the number of shares of Common Stock
     which the aggregate consideration received (determined as provided in
     subsection (7) below) for the issuance of such additional shares would
     purchase at the Exercise Price in effect immediately prior to the date of
     such issuance, and the denominator of which shall be the number of shares
     of Common Stock outstanding immediately after the issuance of such
     additional shares. Such adjustment shall be made successively whenever such
     an issuance is made.

          (5) In case the Company shall issue any securities convertible into or
     exchangeable for its Common Stock, excluding securities issued in
     transactions described in Subsections (2) and (3) above, for a
     consideration per share of Common





                                       -6-

<PAGE>



     Stock (the "Conversion Price") initially deliverable upon conversion or
     exchange of such securities (determined as provided in Subsection (7)
     below) less than the current market price per share (as defined in
     Subsection (8) below) in effect immediately prior to the issuance of such
     securities, or less than the Exercise Price, the Exercise Price shall be
     adjusted immediately thereafter so that it shall equal the lower of (i) the
     price determined by multiplying the Exercise Price in effect immediately
     prior thereto by a fraction, the numerator of which shall be the sum of the
     number of shares of Common Stock outstanding immediately prior to the
     issuance of such securities and the number of shares of Common Stock which
     the aggregate consideration received (determined as provided in Subsection
     (7) below) for such securities would purchase at such current market price
     per share of Common Stock, and the denominator of which shall be the sum of
     the number of shares of Common Stock outstanding immediately prior to such
     issuance and the maximum number of shares of Common Stock of the Company
     deliverable upon conversion of or in exchange for such securities at the
     initial conversion or exchange price or rate or (ii) in the event the
     Conversion Price is equal to or higher than the current market price per
     share but less than the Exercise Price, the price determined by multiplying
     the Exercise Price in effect immediately prior to the date of issuance by a
     fraction, the numerator of which shall be the sum of the number of shares
     outstanding immediately prior to the issuance of such securities and the
     number of shares of Common Stock which the aggregate consideration received
     (determined as provided in subsection (7) below) for such securities would
     purchase at the Exercise Price in effect immediately prior to the date of
     such issuance, and the denominator of which shall be the sum of the number
     of shares of Common Stock outstanding immediately prior to the issuance of
     such securities and the maximum number of shares of Common Stock of the
     Company deliverable upon conversion of or in exchange for such securities
     at the initial conversion or exchange price or rate. Such adjustment shall
     be made successively whenever such an issuance is made.

          (6) Whenever the Exercise Price payable upon exercise of each Warrant
     is adjusted pursuant to Subsections (1), (2), (3), (4) and (5) above, the
     number of Shares purchasable upon exercise of this Warrant shall
     simultaneously be adjusted by multiplying the number of Shares initially
     issuable upon exercise of this Warrant by the Exercise Price in effect on
     the date hereof and dividing the product so obtained by the Exercise Price,
     as adjusted.

          (7) For purposes of any computation respecting consideration received
     pursuant to Subsections (4) and (5) above, the following shall apply:

               (A) in the case of the issuance of shares of Common Stock for
          cash, the consideration shall be the amount of such cash, provided
          that in no case





                                       -7-

<PAGE>



          shall any deduction be made for any commissions, discounts or other
          expenses incurred by the Company for any underwriting of the issue or
          otherwise in connection therewith;

               (B) in the case of the issuance of shares of Common Stock for a
          consideration in whole or in part other than cash, the consideration
          other than cash shall be deemed to be the fair market value thereof as
          determined in good faith by the Board of Directors of the Company
          (irrespective of the accounting treatment thereof), whose
          determination shall be conclusive; and

               (C) in the case of the issuance of securities convertible into or
          exchangeable for shares of Common Stock, the aggregate consideration
          received therefor shall be deemed to be the consideration received by
          the Company for the issuance of such securities plus the additional
          minimum consideration, if any, to be received by the Company upon the
          conversion or exchange thereof (the consideration in each case to be
          determined in the same manner as provided in clauses (A) and (B) of
          this Subsection (7)).

          (8) For the purpose of any computation under Subsections (2), (3), (4)
     and (5) above, the current market price per share of Common Stock at any
     date shall be determined in the manner set forth in Section (c) hereof
     except that the current market price per share shall be deemed to be the
     higher of (i) the average of the prices for 30 consecutive business days
     before such date or (ii) the price on the business day immediately
     preceding such date.

          (9) No adjustment in the Exercise Price shall be required unless such
     adjustment would require an increase or decrease of at least five cents
     ($0.05) in such price; provided, however, that any adjustments which by
     reason of this Subsection (9) are not required to be made shall be carried
     forward and taken into account in any subsequent adjustment required to be
     made hereunder. All calculations under this Section (f) shall be made to
     the nearest cent or to the nearest one-hundredth of a share, as the case
     may be. Anything in this Section (f) to the contrary notwithstanding, the
     Company shall be entitled, but shall not be required, to make such changes
     in the Exercise Price, in addition to those required by this Section (f),
     as it shall determine, in its sole discretion, to be advisable in order
     that any dividend or distribution in shares of Common Stock, or any
     subdivision, reclassification or combination of Common Stock, hereafter
     made by the Company shall not result in any Federal Income tax liability to
     the holders of Common Stock or securities convertible into Common Stock
     (including Warrants).






                                       -8-

          (10) Whenever the Exercise Price is adjusted, as herein provided, the
     Company shall promptly but no later than 10 days after any request for such
     an adjustment by the Holder, cause a notice setting forth the adjusted
     Exercise Price and adjusted number of Shares issuable upon exercise of each
     Warrant, and, if requested, information describing the transactions giving
     rise to such adjustments, to be mailed to the Holders at their last
     addresses appearing in the Warrant Register, and shall cause a certified
     copy thereof to be mailed to its transfer agent, if any. In the event the
     Company does not provide the Holder with such notice and information within
     10 days of a request by the Holder, then notwithstanding the provisions of
     this Section (f), the Exercise Price shall be immediately adjusted to equal
     the lowest Offering Price, Subscription Price or Conversion Price, as
     applicable, since the date of this Warrant, and the number of shares
     issuable upon exercise of this Warrant shall be adjusted accordingly. The
     Company may retain a firm of independent certified public accountants
     selected by the Board of Directors (who may be the regular accountants
     employed by the Company) to make any computation required by this Section
     (f), and a certificate signed by such firm shall be conclusive evidence of
     the correctness of such adjustment.

          (11) In the event that at any time, as a result of an adjustment made
     pursuant to Subsection (1) above, the Holder of this Warrant thereafter
     shall become entitled to receive any shares of the Company, other than
     Common Stock, thereafter the number of such other shares so receivable upon
     exercise of this Warrant shall be subject to adjustment from time to time
     in a manner and on terms as nearly equivalent as practicable to the
     provisions with respect to the Common Stock contained in Subsections (1) to
     (9), inclusive above.

          (12) Irrespective of any adjustments in the Exercise Price or the
     number or kind of shares purchasable upon exercise of this Warrant,
     Warrants theretofore or thereafter issued may continue to express the same
     price and number and kind of shares as are stated in the similar Warrants
     initially issuable pursuant to this Agreement.

     (g) OFFICER'S CERTIFICATE. Whenever the Exercise Price shall be adjusted as
required by the provisions of the foregoing Section, the Company shall forthwith
file in the custody of its Secretary or an Assistant Secretary at its principal
office and with its stock transfer agent, if any, an officer's certificate
showing the adjusted Exercise Price determined as herein provided, setting forth
in reasonable detail the facts requiring such adjustment, including a statement
of the number of additional shares of Common Stock, if any, and such other facts
as shall be necessary to show the reason for and the manner of computing such
adjustment. Each such officer's certificate shall be made available at all
reasonable times for inspection by the holder or any holder of a Warrant





                                       -9-

<PAGE>



executed and delivered pursuant to Section (a) and the Company shall, forthwith
after each such adjustment, mail a copy by certified mail of such certificate to
the Holder or any such holder.

     (h) NOTICES TO WARRANT HOLDERS. So long as this Warrant shall be
outstanding, (i) if the Company shall pay any dividend or make any distribution
upon the Common Stock or (ii) if the Company shall offer to the holders of
Common Stock for subscription or purchase by them any share of any class or any
other rights or (iii) if any capital reorganization of the Company,
reclassification of the capital stock of the Company, consolidation or merger of
the Company with or into another corporation, sale, lease or transfer of all or
substantially all of the property and assets of the Company to another
corporation, or voluntary or involuntary dissolution, liquidation or winding up
of the Company shall be effected, then in any such case, the Company shall cause
to be mailed by certified mail to the Holder, at least fifteen days prior the
date specified in (x) or (y) below, as the case may be, a notice containing a
brief description of the proposed action and stating the date on which (x) a
record is to be taken for the purpose of such dividend, distribution or rights,
or (y) such reclassification, reorganization, consolidation, merger, conveyance,
lease, dissolution, liquidation or winding up is to take place and the date, if
any is to be fixed, as of which the holders of Common Stock or other securities
shall receive cash or other property deliverable upon such reclassification,
reorganization, consolidation, merger, conveyance, dissolution, liquidation or
winding up.

     (i) RECLASSIFICATION, REORGANIZATION OR MERGER. In case of any
reclassification, capital reorganization or other change of outstanding shares
of Common Stock of the Company, or in case of any consolidation or merger of the
Company with or into another corporation (other than a merger with a subsidiary
in which merger the Company is the continuing corporation and which does not
result in any reclassification, capital reorganization or other change of
outstanding shares of Common Stock of the class issuable upon exercise of this
Warrant) or in case of any sale, lease or conveyance to another corporation of
the property of the Company as an entirety, the Company shall, as a condition
precedent to such transaction, cause effective provisions to be made so that the
Holder shall have the right thereafter by exercising this Warrant at any time
prior to the expiration of the Warrant, to purchase the kind and amount of
shares of stock and other securities and property receivable upon such
reclassification, capital reorganization and other change, consolidation,
merger, sale or conveyance by a holder of the number of shares of Common Stock
which might have been purchased upon exercise of this Warrant immediately prior
to such reclassification, change, consolidation, merger, sale or conveyance. Any
such provision shall include provision for adjustments which shall be as nearly
equivalent as may be practicable to the adjustments provided for in this
Warrant. The foregoing provisions of this Section (i) shall similarly apply to
successive reclassifications, capital reorganizations and changes of shares of
Common Stock and to successive consolidations, mergers, sales or conveyances. In
the event that in connection with any such capital reorganization or
reclassification, consolidation, merger, sale or conveyance, additional shares
of Common Stock shall be issued in exchange, conversion, substitution or
payment, in whole or in part,





                                      -10-

for a security of the Company other than Common Stock, any such issue shall be
treated as an issue of Common Stock covered by the provisions of Subsection (1)
of Section (f) hereof.

<PAGE>



500,000 shares of Common Stock owned of record by the Stockholders in the
respective amounts set forth on Exhibit A hereto (the "Escrow Shares"), together
with stock powers executed in blank. The Escrow Agent, by its execution and
delivery of this Agreement hereby acknowledges receipt of the Escrow Shares and
accepts its appointment as Escrow Agent to hold the Escrow Shares in escrow,
upon the terms, provisions and conditions hereof.

     2. This Agreement shall become effective upon the date on which the
Securities and Exchange Commission declares effective the Registration Statement

respect to such Escrow Shares, to the respective Stockholders, if, and only if,
one of the following conditions is met:

     (iv) The Closing Price (as defined herein) of the Company's Common Stock

          Effective Date; or

     (v)  the Company is acquired by or merged into another entity in a
          transaction in which stockholders of the Company receive per share
          consideration (after taking into account any Escrow Shares released
          from escrow in connection with such transaction) at least equal to the
          level set forth in (iv) above.

     (b) As used in this Section 4, the term "Closing Price" shall be subject to
adjustments in the event of any stock dividend, stock distribution, stock split
or other similar event and shall mean:

          exchange or the Nasdaq National Market, the closing sales price of the
          Common Stock as reported by such exchange or market, or on a
          consolidated tape reflecting transactions on such exchange or market;
          or

     (ii) if the principal market for the Common Stock is not a national
          securities exchange or the Nasdaq National Market and the Common Stock
          is quoted

          on the Nasdaq SmallCap Market, the closing bid price of the Common
          Stock as quoted on the Nasdaq SmallCap Market; or

     (iii) if the principal market for the Common Stock is not a national
          securities exchange or the Nasdaq National Market and the Common Stock
          is not quoted on the Nasdaq SmallCap Market, the closing bid for the
          Common Stock as reported by the National Quotation Bureau, Inc.
          ("NQB") or at least two market makers in the Common Stock if
          quotations are not available from NQB but are available from market
          makers.

     (c) The determination of Minimum Revenues and Minimum Pretax Income shall
be (i) calculated exclusive of any extraordinary earnings or charges (including
any charges incurred in connection with the release from escrow of the Escrow
Shares and any Escrow Property in respect thereof pursuant to the provisions of
this paragraph 4); (ii) derived solely from the businesses owned and operated by
the Company as of the closing date of the Public Offering and shall not give
effect to any operations relating to businesses or assets acquired after such
date; and (iii) audited by the Company's independent public accountants.

     (d) If the Escrow Agent has not received the notice provided for in
Paragraph 5 hereof and delivered all of the Escrow Shares and related Escrow
Property in accordance with the provisions of this Paragraph 4 on or prior to
the earlier of (i) the date of the closing of a transaction referred to in
subparagraph 4(a)(v) or (ii) March 31, 2002, the Escrow Agent shall deliver the
certificates representing the remaining Escrow Shares, together with stock
powers executed in blank, and any related Escrow Property to the Company to be
placed in the Company's treasury for cancellation thereof as a contribution to
capital. After such date, the Stockholders shall have no further rights as a
stockholder of the Company with respect to any of the cancelled Escrow Shares.

                                                                               
                                       -4-


<PAGE>



     5. Upon the occurrence or  satisfaction  of any of the events or conditions
specified in Paragraph 4 hereof,  the Company shall  promptly  give  appropriate
notice to the Escrow Agent,  the  Underwriter  (and if the transfer agent of the
Company's Common Stock is different from the Escrow Agent,  such transfer agent)
and present such documentation as is reasonably  required by the Escrow Agent to
evidence the satisfaction of such conditions.

     6. It is understood and agreed by the parties to this Agreement as follows:

          (a) The Escrow Agent is not and shall not be deemed to be a trustee
     for any party for any purpose and is merely acting as a depository and in a
     ministerial capacity hereunder with the limited duties herein prescribed.

          (b) The Escrow Agent does not have and shall not be deemed to have any
     responsibility in respect of any instruction, certificate or notice
     delivered to it or of the Escrow Shares or any related Escrow Property
     other than faithfully to carry out the obligations undertaken in this
     Agreement and to follow the directions in such instruction or notice
     provided in accordance with the terms hereof.

          (c) The Escrow Agent is not and shall not be deemed to be liable for
     any action taken or omitted by it in good faith and may rely upon, and act
     in accordance with, the advice of its counsel without liability on its part
     for any action taken or omitted in accordance with such advice. In any
     event, its liability hereunder shall be limited to liability for gross
     negligence, willful misconduct or bad faith on its part.

          (d) The Escrow Agent may conclusively rely upon and act in accordance
     with any certificate, instruction, notice, letter, telegram, cablegram or
     other written instrument believed by it to be genuine and to have been
     signed by the proper party or parties.

                                                                            
                                       -5-


<PAGE>



          (e) The Company agrees (i) to pay the Escrow Agent's reasonable fees
     and to reimburse it for its reasonable expenses including attorney's fees
     incurred in connection with duties hereunder and (ii) to save harmless,
     indemnify and defend the Escrow Agent for, from and against any loss,
     damage, liability, judgment, cost and expense whatsoever, including counsel
     fees, suffered or incurred by it by reason of, or on account of, any
     misrepresentation made to it or its status or activities as Escrow Agent
     under this Agreement except for any loss, damage, liability, judgment, cost
     or expense resulting from gross negligence, willful misconduct or bad faith
     on the part of the Escrow Agent. The obligation of the Escrow Agent to
     deliver the Escrow Shares to either the Stockholders or the Company shall
     be subject to the prior satisfaction upon demand from the Escrow Agent, of
     the Company's obligations to so save harmless, indemnify and defend the
     Escrow Agent and to reimburse the Escrow Agent or otherwise pay its fees
     and expenses hereunder.

          (f) The Escrow Agent shall not be required to defend any legal
     proceeding which may be instituted against it in respect of the subject
     matter of this Agreement unless requested to do so by the Stockholders and
     indemnified to the Escrow Agent's satisfaction against the cost and expense
     of such defense by the party requesting such defense. If any such legal
     proceeding is instituted against it, the Escrow Agent agrees promptly to
     given notice of such proceeding to the Stockholders and the Company. The
     Escrow Agent shall not be required to institute legal proceedings of any
     kind.

          (g) The Escrow Agent shall not, by act, delay, omission or otherwise,
     be deemed to have waived any right or remedy it may have either under this
     Agreement or generally, unless such waiver be in writing, and no waiver
     shall be valid unless it is in writing,

                                                                   

                                       -6-


<PAGE>



     signed by the Escrow Agent,  and only to the extent  expressly  therein set
     forth. A waiver by the Escrow Agent under the term of this Agreement  shall
     not be  construed  as a bar to, or waiver  of,  the same or any other  such
     right or remedy which it would otherwise have on any other occasion.

          (h) The Escrow Agent may resign as such hereunder by giving 30 days
     written notice thereof to the Stockholders and the Company. Within 20 days
     after receipt of such notice, the Stockholders and the Company shall
     furnish to the Escrow Agent written instructions for the release of the
     Escrow Shares and any related Escrow Property (if such shares and property,
     if any, have not yet been released pursuant to Paragraph 4 hereof) to a
     substitute Escrow Agent which (whether designated by written instructions
     from the Stockholders and the Company jointly or in the absence thereof by
     instructions from a court of competent jurisdiction to the Escrow Agent)
     shall be a bank or trust company organized and doing business under the
     laws of the United States or any state thereof. Such substitute Escrow
     Agent shall thereafter hold any Escrow Shares and any related Escrow
     Property received by it pursuant to the terms of this Agreement and
     otherwise act hereunder as if it were the Escrow Agent originally named
     herein. The Escrow Agent's duties and responsibilities hereunder shall
     terminate upon the release of all shares then held in escrow according to
     such written instruction or upon such delivery as herein provided. This
     Agreement shall not otherwise be assignable by the Escrow Agent without the
     prior written consent of the Company.

     7. The Stockholders shall have the sole power to vote the Escrow Shares and
any securities deposited in escrow under this Agreement while they are being
held pursuant to this Agreement.

     8. (a) Each of the Stockholders agrees that during the term of this
Agreement he will not sell, transfer, hypothecate, negotiate, pledge, assign,
encumber or otherwise dispose of any or all of the Escrow Shares set forth
opposite his name on Exhibit A hereto, unless and until the Company shall have
given the notice as provided in Paragraph 5. This restriction shall not be
applicable to transfers upon death, by operation of law, to family members of
the Stockholders or to any trust for the benefit of the Stockholders, provided
that such transferees agree to be bound by the provisions of this Agreement.

     (b) The Stockholders will take any action necessary or appropriate,
including the execution of any further documents or agreements, in order to
effectuate the transfer of the Escrow Shares to the Company if required pursuant
to the provisions of this Agreement.

     9. Each of the certificates representing the Escrow Shares will bear
legends to the following effect, as well as any other legends required by
applicable law:

     (a)  "The sale, transfer, hypothecation, negotiation, pledge, assignment,
          encumbrance or other disposition of the shares evidenced by this
          certificate are restricted by and are subject to all of the terms,
          conditions and provisions of a certain Escrow Agreement entered into
          among American Stock Transfer & Trust Company, IAT Multimedia, Inc.
          and its Stockholders, dated as of _________, 1997, a copy of which may
          be obtained from IAT Multimedia, Inc.. No transfer, sale or other
          disposition of these shares may be made unless specific conditions of
          such agreement are satisfied.

     (b)  "The shares evidenced by this certificate have not been registered
          under the Securities Act of 1933, as amended. No transfer, sale or
          other disposition of these shares may be made unless a registration
          statement with respect to these shares has become effective under said
          act, or the Company is furnished with an opinion of counsel
          satisfactory in form and substance to it that such registration is not
          required."

                                                                    
                                       -8-

     Upon execution of this Agreement, the Company shall direct the transfer
agent for the Company to place stop transfer orders with respect to the Escrow
Shares and to maintain such orders in effect until the transfer agent and the
Underwriter shall have received written notice from the Company as provided in
Paragraph 5.

     10. Each notice, instruction or other certificate required or permitted by
the terms hereof shall be in writing and shall be communicated by personal
delivery, fax or registered or certified mail, return receipt requested, to the
parties hereto at the addresses set forth below, or at such other address as any

                              IAT MULTIMEDIA, INC.
                             1996 STOCK OPTION PLAN


     1. Purpose. The purposes of the IAT Multimedia, Inc. (the "Company") 1996
Stock Option Plan (the "Plan") are to attract and retain the best available
personnel for positions of substantial responsibility, to provide additional
incentive to key employees, officers, and advisors of the Company and its
subsidiaries and to promote the success of the Company's business.

     2. The Plan. Two types of stock options may be granted under the Plan:
incentive stock options as defined in Section 422 of the Internal Revenue Code
of 1986, as amended (the "Code"), and the regulations promulgated thereunder
("ISOs"), and options that do not qualify as incentive stock options ("NQSOs").
All options shall be exercisable to purchase shares of Common Stock, $.01 par
value (the "Common Stock"), of the Company. Collectively, ISOs and NQSOs are
referred to herein as "Options."

     Subject to Section 6(a), ISOs may be awarded only to employees of the
Company and its subsidiaries, within the meaning of Code Section 424(f),
including employees who may serve as officers and directors.

     NQSOs may be awarded only to employees who may serve as officers and
directors, and anyone other than non-employee Directors whom the Committee
administering the Plan pursuant to Section 3 determines provides substantial
service to the Company.

     To the extent that any Option is not designated as an ISO, or even if so
designated it does not qualify as an ISO, it shall be treated as a NQSO.

     3. Administration. The Plan shall be administered by a committee (the
"Committee") selected by the Board (the "Board") of not fewer than two Outside
Directors. An Outside Director shall mean a director within the meaning of Code
Section 1.162-27, voting as a separate class. The Committee shall act by a
majority of its members at the time in office and eligible to vote on any
particular matter, and such action may be taken either by a vote at a meeting or
in writing without a meeting. Subject to the provisions of the Plan, the
Committee shall from time to time and at its discretion (i) grant Options, (ii)
determine which employees and other individuals performing substantial services
("Grantees") may be granted Options under the Plan; (iii) determine whether any
Option shall be an ISO or NQSO; (iv) determine the number of shares subject to
each Option; (v) determine the term of each Option granted under the Plan; (vi)
determine the date or dates on which the Option shall be exercisable; (vii)
determine the exercise price of any Option; (viii) determine the fair market
value of the Common Stock subject to the Options; (ix) determine the terms of
any agreement pursuant to which Options are granted; (x) amend any such
agreement with the consent of the Grantee; (xi) establish such procedures as it
deems appropriate for a recipient of an award hereunder to designate a
beneficiary to whom any benefits payable in the event of his or here death are
to be made; and (xii) determine any other matters specifically delegated to it
under the Plan or necessary for the proper administration of the Plan.

     The Committee shall also have the final authority to interpret and construe
the terms of the Plan and of any Option and such interpretation and construction
by the Committee shall be final, binding and conclusive upon all persons
including, without limitation, the Company, shareholders of the Company, the
Plan, and all persons claiming an interest in the Plan.

     No member of the Committee or Director shall be liable for any action,
interpretation or construction made in good faith with respect to the Plan or
any Option granted hereunder.

     4. Effectiveness and Termination of Plan. This Plan shall become effective
as of the date of adoption thereof by the Board of the Company, or the date this
Plan is approved by the stockholders, whichever is earlier. This


                                       -1-

<PAGE>



Plan shall terminate on the earliest of:

          a. The tenth anniversary of the effective date as determined under
     this Section 4;

          b. The date when all shares of the Common Stock reserved for issuance
     under the Plan, shall have been acquired through exercise of Options
     granted under the Plan; or

          c. Such earlier date as the Board may determine. Any Option
     outstanding under the Plan at the time of its termination shall remain in
     effect in accordance with its terms and conditions and those of the Plan.

     5. The Stock. The aggregate number of shares of Common Stock which may be
issued under the Plan shall be 500,000 shares. Such number of shares may be set
aside out of the authorized but unissued shares of Common Stock not reserved for
any other purpose or out of shares of Common Stock held in or acquired for the
treasury of the Company. All or any shares of Common Stock subject under this
Plan to an Option which, for any reason, terminates unexercised as to such
shares, may again be subjected to an Option under the Plan. No Grantee may
receive grants in respect of more than 100,000 shares of Common Stock.

     6. Grant, Terms and Conditions of Options. Options may be granted by the
Committee at any time and from time to time prior to the termination of the
Plan. Each Option granted under the Plan shall be evidenced by an agreement in a
form approved by the Committee. The terms and conditions of such Option
agreement need not be identical with respect to each Grantee, but each Option
agreement will evidence on its face whether it is an ISO or a NQSO. For purposes
of this Section, an Option shall be deemed granted on the date the Committee
selects an individual to be a Grantee, determines the number of shares to be
issued pursuant to such Option and specifies the terms and conditions of the
Option. Except as hereinafter provided, Options granted pursuant to the Plan
shall be subject to the following terms and conditions:

          a. Grantee. Subject to Section 2 hereof, the Grantees of any Options
     hereunder shall be such key employees of the Company and its subsidiaries,
     within the meaning of Code Section 424(f), as determined by the Committee,
     who have substantial responsibility in the direction of the Company and its
     subsidiaries, and anyone else whom the Committee determines provides
     substantial and important services to the Company except that in no event
     shall a non-employee Director of the Company be a Grantee under this Plan.

          b. Price and Exercise. The purchase price of the shares of Common
     Stock upon exercise of an ISO shall be no less than the fair market value
     of the shares at the time of grant of an ISO; provided, however, if an ISO
     is granted to a person owning stock of the Company possessing more than 10%
     of the total combined voting power of all classes of stock of the Company
     as defined in Code Section 422 ("10% Shareholder"), the purchase price
     shall be no less than 110% of the fair market value of the shares. The fair
     market value of the Common Stock shall be the closing price of publicly
     traded Common Stock on the national securities exchange on which the Common
     Stock is listed (if the Common Stock is so listed) or on the Nasdaq
     National Market System (if the Common Stock is regularly quoted on the
     Nasdaq National Market System), or, if not so listed or regularly quoted,
     the mean between the closing bid and asked prices of publicly traded Common
     Stock in the over-the-counter market, or, if such bid and asked prices
     shall not be available, as reported by any nationally recognized quotation
     service selected by the Company, or as determined by the Committee in a
     manner consistent with the provisions of the Code.

     The purchase price of the shares of Common Stock upon exercise of a NQSO
     may be any price set by the Committee; provided that the exercise price of
     any grant to an employee required to be named on the Summary Compensation
     Table of the Company's annual proxy statement under the rules and
     regulations promulgated under the Securities Exchange Act of 1934, as
     amended, shall not be lower than the fair market


                                       -2-

<PAGE>



     value of the underlying Common Stock on the date of grant which constitutes
     a performance goal under Section 162(m) of the Internal Revenue Code of
     1986, as amended.

     The notice of the exercise of any Option shall be accompanied by payment in
     full of the Option price. The purchase price shall be paid in United States
     dollars in cash or by certified or cashier's check payable to the order of
     the Company at the time to purchase. At the discretion of the Committee,
     the purchase price may be paid with: (i) stock of the Company (Common Stock
     already owned by, and in the possession of, the Grantee); or (ii) any
     combination of United States dollars or stock of the Company. Anything
     contained herein to the contrary notwithstanding, any required withholding
     tax shall be paid by the Grantee in full in United States dollars in cash
     or by certified or cashier's check at the time of exercise of the Option.
     Shares of stock of the Company used to satisfy the exercise price of an
     Option shall be valued at their fair market value as determined by the
     Committee, as of the close of business on the day immediately preceding the
     date of exercise.

     In lieu of the notice of exercise procedures set forth above, the Committee
     may prescribe cashless exercise or other exercise methods pursuant to which
     a broker or financial intermediary assists in the exercise by an amount of
     shares sufficient to provide the exercise plus any required with holdings.

     If required by the Company, such notice of exercise of an Option shall be
     accompanied by the Grantee's written representation that the shares being
     acquired are purchased for investment and not for distribution;
     acknowledging that such shares have not been registered under the
     Securities Act of 1933, as amended (the "1933 Act"); and agreeing that such
     shares may not be sold or transferred unless there is an effective
     Registration Statement for them under the 1933 Act, or, in the opinion of
     counsel, such sale or transfer is not in violation of the 1933 Act.

          The purchase price shall be subject to adjustment, but only as
     provided in Section 7 hereof.

          c. Vesting. Options shall vest in accordance with the schedule
     established for each Grantee; provided, however, an Option may be
     immediately exercisable in accordance with Section 6(g) below.

          d. Forfeiture. Notwithstanding anything contained herein to the
     contrary, the right (whether or not vested) of a Grantee to exercise his or
     her outstanding Options, if any, shall be forfeited if (i) the Grantee
     shall enter into a business or employment which the Committee determines to
     be detrimentally competitive with the Company or substantially injurious to
     the Company's financial interests; or (ii) the Grantee is discharged from
     employment with the Company for cause; or (iii) the Grantee performs acts
     of willful malfeasance or gross negligence in a matter of material
     importance to the Company.

          e. Additional Restrictions on Exercise of an ISO. The aggregate fair
     market value of Common Stock (determined at the time an ISO is granted) for
     which an ISO is exercisable for the first time by a Grantee during any
     calendar year (under all plans of the Company and its subsidiaries or
     parent) shall not exceed $100,000.

          f. Duration of Options. Options may be granted for terms of up to but
     not exceeding ten (10) years from the effective date the particular Option
     is granted; provided, however, that ISOs granted to a 10% Shareholder may
     be for a term of up to but not exceeding five (5) years from the effective
     date the particular ISO is granted.

          g. Termination of Employment. Upon the termination of a Grantee's
     employment with the Company, his or her rights to exercise an Option then
     held by such Grantee shall be only as follows:




                                       -3-

<PAGE>



               i. Retirement. If the Grantee's employment is terminated because
          he or she has attained the age which the Company may from time to time
          establish as the retirement age for any class of its employees, or in
          accordance with the age specified in an employment agreement with a
          Grantee he or she may, with the consent of the Company within three
          months following such termination, exercise the Option with respect to
          all or any part of the shares subject thereto, regardless of whether
          the Grantee had the right to purchase such shares at the time of
          termination of employment. However, in the event of his or her death
          prior to the end of the three-month period after the aforesaid
          termination of his or here employment, his or her estate shall have
          the right to exercise the Option within one (1) year following such
          termination with respect to all or any part of the shares subject
          thereto, regardless of whether the Grantee had the right to purchase
          such shares at the time of termination of employment.

               ii. Death. In the case of a Grantee who dies while employed by
          the Company, his or her estate shall have the right for a period of
          one (1) year following the date of such death to exercise the Option
          to the extent the Grantee had the right to purchase such shares on the
          day immediately prior to his or her death.

               iii. Disability. In the case of a Grantee whose employment with
          the Company is terminated by disability, as defined in Code Section
          22(e)(3), he or she shall have the right for a period of one (1) year
          of the disability to exercise the Option to the extent the right had
          occurred prior to the date of his or her disability.

               iv. Other Reasons. In the case of a Grantee whose employment is
          terminated for any reason other than those provided above under
          "Retirement," Death," or "Disability," the Grantee or his or her
          estate (in the event of his or her death after such termination) may,
          within the 30-day period following such termination, exercise the
          Option to the extent the right to exercise had occurred prior to such
          termination.

     For purposes of this Section 6(g), "termination of employment" shall mean
     the termination of a Grantee's employment with the Company or a subsidiary
     or a parent. A Grantee employed by a subsidiary shall also be deemed to
     have a termination of employment if the subsidiary ceases to be a
     subsidiary of the Company, and the Grantee does not immediately thereafter
     become an employee of the Company or of a subsidiary or the parent. Any
     other Grantee who is not otherwise an employee of the Company shall be
     considered to have terminated employment when substantial services, as
     determined by the Committee, are no longer provided to the Company by the
     Grantee.

     Also for purposes of this Section 6(g), a Grantee's "estate" shall mean his
     or her legal representatives upon his or her death or any person who
     acquires the right to exercise an Option by reason of the Grantee's death.
     The Committee may in its discretion require the transferee of a Grantee to
     supply it with written notice of the Grantee's death or disability and to
     supply it with a copy of the will (in the case of the Grantee's death) or
     such other evidence as the Committee deems necessary to establish the
     validity of the transfer of an Option.

          h. Transferability of Option and Shares Acquired Upon Exercise of
     Option. Options shall not be transferred other than to members of the
     holder's family, trusts and charities. Any other transfers are permissible
     only upon prior written approval of the Committee. Notwithstanding the
     above, the option agreement accompanying the issuance of any incentive
     stock options shall limit the transferability of such ISOs to the extent
     required by the then applicable tax provisions governing the qualification
     of ISOs. Except as limited by applicable securities laws and the provisions
     of Sections 6(b), 6(j), 8 and 14 hereof, shares of Common Stock acquired
     upon exercise of Options hereunder shall be freely tradeable.



                                       -4-

<PAGE>



          i. Modifications, Extension and Renewal of Options. Subject to the
     terms and conditions and within the limitations of the Plan, the Committee
     may modify, extend or renew outstanding Options granted under the Plan, or
     accept the surrender or outstanding Options (up to the extent not
     theretofore exercised) and authorize the granting of new Options in
     substitution therefor (to the extent not theretofore exercised). The
     Committee shall not, however, with respect to ISOs, modify any outstanding
     Options so as to specify a lower Option price or accept the surrender of
     outstanding Options and authorize the granting of new Options in
     substitution therefor specifying a lower price. Notwithstanding the
     foregoing, no modification of an Option shall, without the consent of the
     Grantee, alter or impair any rights or obligations under any Option
     theretofore granted under the Plan.

          j. Shares Held for Investment. Each Option agreement may contain an
     undertaking that, upon demand by the Committee for such a representation,
     the Grantee, or any person acting under Section 6(g), shall deliver to the
     Committee at the time of any exercise of an Option a written representation
     that the shares to be acquired upon such exercise are to be acquired for
     investment and not for resale or with a view to the distribution thereof.
     Upon such demand, delivery of such representation prior to the delivery of
     any shares issued upon exercise of an option shall be a condition precedent
     to the right of the Grantee or such other person to purchase any shares of
     Common Stock.

          k. Other Terms and Conditions. Options may contain such other
     provisions, which shall not be inconsistent with any of the foregoing
     terms, as the Committee shall deem appropriate.

     7. Adjustment of the Changes in the Stock.

     a. In the event the shares of Common Stock, as presently constituted, shall
be changed into or exchanged for a different number or kind of shares of stock
or other securities of the Company or of another corporation (whether by reason
of merger, consolidation, recapitalization, reclassification, split, reverse
split, combination of shares, or otherwise) or if the number of such shares of
Common Stock shall be increased through the payment of a stock dividend, then
there shall be substituted for or added to each share of Common Stock
theretofore appropriated or thereafter subject or which may become subject to an
Option under this Plan, the number and kind of shares of stock or other
securities into which each outstanding share of Common Stock shall be so
changed, or for which each such share shall be exchanged, or to which each such
share shall be entitled, as the case may be. Outstanding Options shall also be
appropriately amended as to price and other terms as may be necessary to reflect
the foregoing events. In the event there shall be any other change in the number
or kind of the outstanding shares of the Common Stock, or of any stock or other
securities into which such Common Stock shall have been changed, or for which it
shall have been exchanged, then, if the Board shall, in its sole discretion,
determine that such change equitably requires as adjustment in any Option
theretofore granted or which may be granted under the Plan, such adjustments
shall be made in accordance with such determination.

     b. Fractional shares resulting from any adjustment in Options pursuant to
Section 7 may be settled in cash or otherwise as the Committee shall determine.
Notice of any adjustment shall be given by the Company to each holder of an
Option which shall have been so adjusted and such adjustment (whether or not
such notice is given) shall be effective and binding for all purposes of the
Plan.

     8. Securities Law Requirements. No Option granted pursuant to this Plan
shall be exercisable in whole or in part, nor shall the Company be obligated to
sell any shares of Common Stock subject to any such Option, if such exercise and
sale would, in the opinion of counsel for the Company, violate the 1933 Act (or
other Federal or State statutes having similar requirements), as it may be in
effect at that time. In this regard, the Committee may demand the
representations described in Section 6(b) and Section 6(j).

     Each Option shall be subject to the further requirement that, if at any
time the Committee shall determine


                                       -5-

<PAGE>



in its discretion that the listing or qualification of the shares of Common
Stock subject to such Option under any securities exchange requirements or under
any applicable law, or the consent or approval of any governmental regulatory
body, is necessary as a condition of, or in connection with, the granting of
such Option or the issue of shares thereunder, such Option may not be exercised
in whole or in part, unless such listing, qualification, consent or approval
shall have been affected or obtained free of any conditions not acceptable to
the Board.

     No person who acquires shares of Common Stock under the Plan may, during
any period of time that such person is an affiliate of the Company within the
meaning of the rules and regulations of the Securities and Exchange Commission
under the 1933 Act, sell such shares of Common Stock, unless such offer and sale
is made (i) pursuant to an effective registration statement under the 1933 Act,
which is current and includes the shares to be sold, or (ii) pursuant to an
appropriate exemption from the registration requirement of the 1933 Act, such as
that set forth in Rule 144 promulgated under the 1933 Act.

     9. Amendment of the Plan.

     The Board may amend the Plan at any time, except that approval of the
holders of a majority of the outstanding voting stock of the Company is required
for amendments which:

          a. extend the term of the Plan beyond ten years;

with such law, regulations and requirements, that the recipient of any award
hereunder make such covenants, agreements and representations as the Committee,
in its sole discretion, deems necessary or desirable, including, without
limitation, a written representation from a stockholder that the shares are
being purchased for investment and not for distribution, acknowledging that such

counsel to the Company, that such sale or transfer is not in violation of the
1933 Act.

shall have any rights as a stockholder with respect to any shares subject to his
or her Option prior to the date on which he or she is recorded as the holder of
such shares on the records of the Company. No Grantee of any Option shall have
the rights of a stockholder until he or she has paid in full the Option price.

     17. Notice. Notice to the Committee shall be deemed given if in writing and
mailed to the Secretary of the Company at its principal executive offices by
first class, certified mail at the then principal office of the Company.

and all Option agreements entered into pursuant thereto shall be construed and

          Common Stock issuable upon conversion of such Series A Preferred Stock
          and upon exercise of the Warrant) will be free and clear from all
          Encumbrances other than those created by, or imposed upon, the holders

delivered to the Investor IAT's audited consolidated balance sheet as of
December 31, 1995, and the related statements of operations, cash flows and
stockholder's equity as of, and for the twelve months ended, December 31, 1995
(the "Financial Statements"). Upon delivery to the Investor, the Financial
Statements will be complete and correct in all material respects and will have
been prepared in accordance with United States generally accepted accounting
principles applied on a consistent basis throughout the periods indicated. Prior
to the Closing, Holdings or IAT will also provide the Investor with IAT's
consolidated balance sheet as of June 30, 1996, and the related statements of
operations, cash flows and stockholder's equity as of, and for the six months

Financial Statements will fairly present the financial condition and results of
operations of IAT as of the dates and during the periods indicated therein,
subject to normal year-end audit adjustments which are neither individually nor
in the aggregate expected to be material. As of the date of the balance sheet
included in the Interim Financial Statements (the "Interim Balance Sheet Date"),
to the best of the Company's knowledge, IAT has no liabilities or obligations of
any nature (absolute, accrued, contingent or otherwise) which were not fully
reflected or reserved against in the Financial Statements, and all reserves
established by IAT and set forth on such balance sheet were adequate for the
purposes for which they were established.

     2.6 Governmental Consents. Except as listed on Exhibit B, no consent,
approval, order, or authorization of, or registration, qualification,
designation, declaration or filing with, any Swiss, German or United States
federal, state, local or provincial governmental authority on the part of
Holdings or any Subsidiary is required in connection with the consummation of
the transactions contemplated by this Agreement. To the best of the

            

                                       -4-

Company's knowledge, Holdings and each Subsidiary has complied (and in carrying
out their respective businesses Holdings and each Subsidiary will be in
compliance) with all laws, ordinances and regulations applicable to it and its
business, which the failure to comply with would, either individually or in the
aggregate, have a materially adverse effect upon Holdings and its Subsidiaries
taken as a whole. Holdings and each Subsidiary has obtained all Swiss, German
and United States federal, state, local and foreign governmental licenses and
permits material to and necessary in the conduct of their respective businesses,
such licenses and permits are in full force and effect, no material violations
are or have been recorded in respect of any such licenses or permits, and no
proceeding is pending or, to the best of the Company's knowledge, threatened to
revoke or limit any thereof.

     2.7 Litigation. Except as described on Exhibit B hereto, there is no
action, suit, proceeding, or investigation pending or to the Company's knowledge
currently threatened against Holdings or any Subsidiary (nor, to the Company's
knowledge, is there any reasonable basis therefor).

     2.8 Patents and Trademarks.

          (a) Except as set forth on Exhibit B, Holdings and each Subsidiary has
     title and ownership of all Intellectual Property (as defined below) (i)

     Except as shown on Exhibit B, there are no outstanding options, licenses,
     or agreements of any kind relating to the Intellectual Property, nor is
     Holdings or any Subsidiary bound by or a party to any options, licenses, or
     agreements of any kind with respect to the patents, trademarks, service
     marks, trade names, copyrights, trade secrets, licenses, information,
     proprietary rights, and processes of any other person or entity. To the
     Company's knowledge the Intellectual Property does not violate any of the
     patents, trademarks, service marks, trade names, copyrights, or trade
     secrets or other proprietary rights of any other person or entity. The
     Company is not aware that any of the employees of Holdings or any
     Subsidiary is obligated under any contract (including licenses, covenants,
     or commitments of any nature) or other agreement, or subject to any
     judgment, decree or order of any court or administrative agency, that would
     interfere with the use of such employee's best efforts to promote the
     interests of Holdings and each Subsidiary or that would conflict with the
     business of Holdings and each Subsidiary as proposed to be conducted.
     Except as disclosed on Exhibit B, none of the past or present employees,
     officers, directors, shareholders or consultants of Holdings or any
     Subsidiary has any rights in any of the Intellectual Property. Neither the
     execution nor delivery of this Agreement, the Rights Agreement, the
     Marketing Agreement or the Warrant, nor the carrying on of the business of
     Holdings and each Subsidiary by the employees of Holdings and each
     Subsidiary, nor the conduct of the business of Holdings and each Subsidiary
     as proposed, will, to the Company's knowledge, conflict with or result in a
     breach of the terms, conditions or provisions of, or constitute a default
     under, any contract, covenant or instrument under which any of such
     employees is now obligated. Exhibit B sets

                    
                                       -5-

     Subsidiary or required to operate the business of Holdings or any
     Subsidiary or other Intellectual Property that (i) is owned by entities
     other than Holdings or any Subsidiary and (ii) is necessary to implement,
     operate or maintain the business of Holdings and each Subsidiary as
     presently operated.

     2.9 Compliance with Other Instruments. Except as noted in Exhibit B hereto,
neither Holdings nor any Subsidiary is in violation or default of any provisions
of its respective Certificate of Incorporation or By-laws (or other
organizational documents) or of any instrument, judgment, order, writ, decree,
or contract to which it is a party or by which it is bound, the violation or
default of which would have a material adverse effect on Holdings and its
Subsidiaries taken as a whole. Neither the execution and delivery of this
Agreement nor the consummation of the transactions contemplated hereby will (a)
violate any provision of the respective Certificate of Incorporation or By-Laws
(or other organizational documents) of Holdings or any Subsidiary or (b)
violate, or be in conflict with, or constitute a default (or an event which,
with notice or lapse of time or both, would constitute a default) under, or
result in the termination of, or accelerate the performance required by, or
excuse performance by any person of any of its obligations under, or cause the
acceleration of the maturity of any debt or obligation pursuant to, or result in
the creation or imposition of any Encumbrance upon any property or assets of
Holdings or any Subsidiary under, any agreement or commitment to which Holdings
or any Subsidiary is a party or by which any of its respective property or
assets is bound, or to which any of the property or assets of Holdings or any
Subsidiary is subject, or (c) violate any statute or law or any judgment,
decree, order, regulation or rule of any court or other governmental authority
applicable to Holdings or such Subsidiary. Neither Holdings nor any Subsidiary
has any knowledge of any termination or material breach or anticipated
termination or material breach by the other parties to any material contract or
commitment to which it is a party or to which any of its assets is subject. To
the knowledge of the respective parties, there are no warranty claims or other
uninsured claims against Holdings or any Subsidiary under completed contracts
which might involve a material monetary liability which is not reserved against
in the Financial Statements.

statement of a material fact or omits to state a material fact necessary to make
the statements herein or therein not misleading in light of the circumstances in
which they were made.

     2.12 Registration Rights. Except as provided in Section 1 of the Investor's
Rights Agreement, and as set forth on Exhibit B hereto, Holdings has not granted
or agreed to grant any registration rights, including piggyback rights, to any
person or entity.

     2.13 Title to Property and Assets. Except as set forth on Exhibit B hereto,
Holdings and each Subsidiary has good and marketable title to its property and
assets free and clear of all mortgages, liens, loans, and encumbrances, except
such encumbrances and liens which arise in the ordinary course of business and
do not materially impair Holdings' or such Subsidiary's ownership or use of such
property or assets. With respect to the property and assets it leases, Holdings
and each Subsidiary is in compliance in all material respects with such leases
and, to the Company's knowledge, holds a valid leasehold interest free of any
liens, claims, or encumbrances. All of Holdings' and each Subsidiary's
properties and assets are, in all material respects, in good operating and
usable condition, subject to normal wear and tear.

     2.14 Labor Agreements and Actions; Employee Benefits. Neither Holdings nor
any Subsidiary is bound by or subject to (and none of its assets or properties
is bound by or subject to) any written or oral, express or implied, contract,
commitment, or arrangement with any labor union, and no labor union has
requested or, to the knowledge of the Company, has sought to represent any of
the employees, representatives, or agents of Holdings or any Subsidiary. There
is no strike or other labor dispute involving Holdings or any Subsidiary
pending, or, to the knowledge of the Company, threatened, which could have a
material adverse effect on the assets, properties, financial condition,
operating results, or business of Holdings and its subsidiaries taken as a whole
(as such business is presently conducted and as it is proposed to be conducted
taken as a whole), nor is the Company aware of any labor organization activity
involving its employees. Except as set forth on Exhibit B, neither Holdings nor
any Subsidiary has any employment contract, deferred compensation agreement or
bonus, incentive or profit-sharing plans currently in force and effect, and
there are no existing or proposed material arrangements or transactions between
Holdings or any Subsidiary and any officer or director or holder of capital
stock of Holdings or any Subsidiary, other than transactions referred to in this
Agreement. To the best of the Company's knowledge, no officer or key employee of
Holdings or any Subsidiary is in violation of (a) any material term of any
employment agreement, non-disclosure agreement, noncompete agreement or other
similar agreement with any previous employer of such employee (and the
employment of such employee with Holdings or any Subsidiary will not result in a
violation of any such agreement) or (b) any obligation binding on such employee
which would prohibit the use of information obtained from such employee which
Holdings or any Subsidiary has used or proposes to use.

     2.15 Tax Matters. Holdings and each Subsidiary (i) has timely filed all tax
returns that are required to have been filed by it with all appropriate
governmental agencies (and all such returns are true and correct and fairly
reflect in all material respects its operations for tax




                                       -8-

<PAGE>



purposes); and (ii) has timely paid all taxes owed or assessments by it (other
than taxes the validity of which are being contested in good faith by
appropriate proceedings and which are reserved) and all such returns are true
and correct in all material respects. The assessment of any additional taxes for
periods for which returns have been filed is not expected to exceed the recorded
liability therefor and, to the Company's knowledge, there are no material
unresolved questions or claims concerning Holdings' or any Subsidiary's tax
liability. Neither Holdings' nor any Subsidiary's tax returns have been reviewed
or audited by any taxing authority. There is no pending dispute with any taxing
authority relating to any of said returns.

     2.16 Insurance. All insurable properties of Holdings and each Subsidiary
are insured for the benefit of Holdings or each Subsidiary against such risks as
are usually insured against, and in such amounts as are usually obtained, by
persons owning or operating similar properties in the locality where such
properties are located, under policies issued by insurers of recognized
responsibility. Exhibit B hereto sets forth a description of the liability
insurance carried by Holdings and each Subsidiary, including policy amounts,
deductibles, carriers and coverage.

the Rights Agreement.

     4.2 No Unregistered Distribution. The Series A Preferred Stock to be

investment for the Investor's own account, without any view to the unregistered
public distribution or resale thereof, all without prejudice, however, to the

A Preferred Stock at the Closing ("Permitted Affiliate Transferees") at any time
lawfully to sell or otherwise to dispose of all or any part of the Series A
Preferred Stock pursuant to registration, any exemption therefrom under the Act,
applicable state securities laws and as set forth in Section 7.7.

     4.3 Restricted Securities. The Investor understands that the Series A

Investor acknowledges that it has been provided access to all information
requested by it in order to evaluate the merits and risks of an investment in
the Series A Preferred Stock.

     4.5 Legends. It is understood that the certificates evidencing the Series A
Preferred Stock may bear one or all of the following legends:

          (a) "THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
     ACT OF 1933, AS AMENDED. THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR
     HYPOTHECATED IN THE ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH

     UNDER SUCH ACT."

          (b) Any legend required by the laws of the State of Delaware.

satisfactory to Holdings to the effect that such legend is not required in order
to establish compliance with any provisions of the Act, or at such time as the
holder of such shares satisfies the requirements of Rule 144(k) under the Act,
provided that Rule 144(k) as then in effect does not differ substantially from
Rule 144(k) as in effect as of the date of this Agreement, and provided further

in carrying out its businesses the Investor will be in compliance) with all
laws, ordinances and regulations applicable to it and its business, which the

of Incorporation or By-laws (or other organizational documents) or of any
instrument, judgment, order, writ, decree, or contract to which it is a party or
by which it is bound, the violation or default of which would have a material
adverse effect on the Investor. Neither the execution and delivery of this

                                                                   


                                      -11-

Agreement nor the consummation of the transactions contemplated hereby will (a)
violate any provision of the Certificate of Incorporation or By-Laws (or other
organizational documents) of the Investor or (b) violate, or be in conflict
with, or constitute a default (or an event which, with notice or lapse of time
or both, would constitute a default) under, or result in the termination of, or
accelerate the performance required by, or excuse performance by any person of
any of its obligations under, or cause the acceleration of the maturity of any
debt or obligation pursuant to, or result in the creation or imposition of any
Encumbrance upon any property or assets of the Investor under, any agreement or
commitment to which the Investor is a party or by which any of its respective
property or assets is bound, or to which any of the property or assets of the
Investor is subject, or (c) violate any statute or law or any judgment, decree,
order, regulation or rule of any court or other governmental authority

     and management stockholders of Holdings to be identified at the Closing
     (the "Management Stockholders") shall, within five business days of the
     Closing of the IPO, issue to the Non-Management Stockholders such
     additional number of shares of Common Stock as shall have a value equal to

                                      -15-

security convertible into shares of capital stock) of IAT or IAT Germany, it
being the intention of the parties that IAT shall remain a direct or indirect
wholly-owned subsidiary of Holdings and IAT Germany shall remain a direct or
indirect subsidiary of Holdings.

     7.7 Right of First Refusal. (a) From the Closing until June 30, 1997, the
Investor may not sell, transfer or dispose of ("Transfer") any of its shares of
Series A Preferred Stock (or Common Stock issued upon conversion thereof or upon
exercise of the Warrant), and after June 30, 1997, the Investor may not Transfer
any of its shares of Series A Preferred Stock (or Common Stock issued upon
conversion thereof or upon exercise of the Warrant), except in accordance with
the following procedures:

          (i) If the Investor desires to Transfer all or any part of the
     Investor's shares of Series A Preferred Stock, the Investor shall submit a
     written offer (the "Offer") to sell such shares of Series A Preferred Stock
     (together, the "Offered Shares") to Holdings and the Stockholders, which
     Offer shall specify the number of Offered Shares proposed to be sold, the
     total number of shares of Series A Preferred Stock owned by the Investor,
     and the terms and conditions, including price, at which the shares of
     Series A Preferred Stock are being offered to Holdings and the
     Stockholders, and such terms shall not be more favorable to the Investor
     than the terms offered to Investor by the third party.

          (ii) Holdings shall have the first right to purchase all of the
     Offered Shares. In the event that Holdings determines not to purchase any
     of the Offered Shares or less than all of the Offered Shares, each
     Stockholder shall have the right to purchase that number of Offered Shares
     as shall be equal to the number of Offered Shares not purchased by Holdings
     multiplied by a fraction, the numerator of which shall be the number of
     shares of Common Stock then owned by such Stockholder and the denominator
     of which shall be the aggregate number of shares then owned by all of the
     Stockholders (the "Pro Rata Fraction"). In all instances, the Stockholders
     shall only have the right, but not the obligation, to purchase such Offered
     Shares as are not purchased by Holdings.

          (iii) Stockholders shall have a right of oversubscription such that if
     any Stockholder fails to accept the Offer as to its or his full Pro Rata
     Fraction, the other Stockholders shall, among them, have the right to
     purchase up to the balance of the Offered Shares not so purchased. Such
     right of oversubscription may be exercised by a Stockholder by accepting
     the Offer as to more than its or his Pro Rata Fraction. If, as a result
     thereof, such oversubscriptions exceed the total number of Offered Shares
     available in respect of such oversubscription privilege, the
     oversubscribing Stockholders shall be cut back with respect to their
     oversubscriptions so as to sell the Offered Shares as nearly as possible in
     accordance with their respective Pro Rata Fractions or as they may
     otherwise agree among themselves.

          (iv) If Holdings or a Stockholder desires to purchase all or any part
     of the Offered Shares, Holdings or such Stockholder (a "Purchasing
     Stockholder") shall communicate in writing its or his election to purchase
     (an "Acceptance") to the Investor, which

                                                                             
                                      -16-

<PAGE>



     Acceptance shall state the number of Offered Shares Holdings or the
     Purchasing Stockholder desires to purchase and shall be delivered in person
     or mailed to the Investor at the address set forth in the Offer, with a
     copy to Holdings and the other Stockholders, within 20 days of the date the
     Offer was made. Sale of the Offered Shares to be sold to Holdings or the
     Purchasing Stockholders pursuant to this Section 7.7 shall be made at the
     offices of the Investor on the thirtieth day following the expiration of
     the 20-day period after the Offer is made (or if such thirtieth day is not
     a business day, then on the next succeeding business day). Such sales shall
     be effected by the Investor's delivery to Holdings or each Purchasing
     Stockholder, as the case may be, of a certificate or certificates
     evidencing the Offered Shares to be purchased by it or him, duly endorsed
     for transfer to Holdings or the Purchasing Stockholder, as the case may be,
     which shares shall be delivered free and clear of all liens, charges,
     claims and encumbrances of any nature whatsoever, against payment to the
     Investor of the purchase price therefor by Holdings or such Purchasing

not apply to any liability resulting from Holdings', IAT's or IAT Germany's
fraud, intentional misrepresentation or intentional failure to perform or comply
with any agreement contained herein or in the Rights Agreement, the Marketing
Agreement or the Warrant and Holdings, IAT and IAT Germany shall be liable for
all losses, damages, costs and expenses with respect thereto. Notwithstanding
the foregoing, in the event that a court of competent jurisdiction having final
adjudicative authority and from which no appeal is available shall determine
that the Investor is not entitled to indemnification, then the Investor shall
not be entitled to recover its legal fees with respect to such claim from
Holdings, IAT or IAT Germany.

     8.2. Indemnification by Investor. In the event that the transactions

the Warrant, and any and all actions, suits, proceedings, elections, demands,
assessments, judgments, costs and expenses, including without limitation,
reasonable legal fees and expenses, incident to any of the foregoing or incurred
in investigating or attempting to avoid same or to oppose the imposition
thereof, or in enforcing this indemnity; provided, that the aggregate liability
of the Investor under this Section 8.2 shall be limited to $1,500,000 and
provided, further, that Investor shall have no liability pursuant to this
Section 8.2 until the aggregate of all losses, damages, costs and expenses,
including reasonable legal fees, exceeds $25,000, except that this proviso shall
not apply to any liability resulting from Investor's fraud, intentional
misrepresentation or intentional failure to perform or comply with any agreement
contained herein or in the Rights Agreement, the Marketing Agreement or the
Warrant and Investor shall be liable for all losses, damages, costs and expenses
with respect thereto. Notwithstanding the foregoing in the event that a court of
competent jurisdiction having final adjudicative authority and from which no
appeal is available shall determine that Holdings is not entitled to
indemnification then Holdings shall not be entitled to recover its legal fees
with respect to such claim from the Investor.

     8.3. Procedures for Indemnification. Promptly after receipt by an
indemnified party under sections 8.1 or 8.2 of notice of the commencement of any
action for which indemnification may be available under section 8.1 or 8.2 such
indemnified party shall, if a claim in respect thereof is to be made against an
indemnifying party under such section, give notice to the indemnifying party of
the commencement thereof, but the failure so to notify the indemnifying party
shall not relieve it of any liability that it may have to any indemnified party
except to the extent the indemnifying party demonstrates that the defense of
such action is prejudiced thereby. In case any such action shall be brought
against an indemnified party and it shall give notice to the indemnifying party
of the commencement thereof, the indemnifying party shall be entitled to
participate therein and, to the extent that it shall elect, to assume the
defense thereof with counsel

                                              

                                      -18-

<PAGE>



reasonably satisfactory to such indemnified party and, after notice from the
indemnifying party to such indemnified party of its election so to assume the
defense thereof, the indemnifying party shall not be liable to such indemnified
party under such section for any fees of other counsel or any other expenses, in
each case subsequently incurred by such indemnified party in connection with the
defense thereof, other than reasonable costs of investigation and costs and
expenses of legal counsel, if the indemnified party and the indemnifying party
are both parties to the action and the indemnified party has been advised by
counsel that there may be one or more defenses available to it and not available
to the indemnifying party. If an indemnifying party assumes the defense of such
an action, (a) no compromise or settlement thereof may be effected by the
indemnifying party without the indemnified party's consent (which shall not be
unreasonably withheld) unless (i) there is no finding or admission of any
violation of law or any violation of the rights of any person and no effect on
any other claims that may be made against the indemnified party and (ii) the
sole relief provided is monetary damages that are paid in full by the
indemnifying party and (b) the indemnifying party shall have no liability with
respect to any compromise or settlement thereof effected without its consent
(which shall not be unreasonably withheld). If notice is given to an
indemnifying part of the commencement of any action and it does not, within ten
days after the indemnified party's notice is given, give notice to the
indemnified party of its election to assume the defense thereof, the
indemnifying party shall be bound by any determination made in such action or
any compromise or settlement thereof effected by the indemnified party.
Notwithstanding the foregoing, if an indemnified party determines in good faith
that there is a reasonable probability that an action may materially and
adversely affect it or its affiliates other than as a result of monetary
damages, such indemnified party may, by notice to the indemnifying party, assume
the exclusive right to defend, compromise or settle such action, but the
indemnifying party shall have the right to participate in such action and not be
bound by any determination of an action so defended or any compromise or
settlement thereof effected without its consent (which shall not be unreasonably
withheld).

         III.  Rights of Employees to Intellectual Property

         Under German law according to the employee-invention-act
         (Arbeitnehmererfindungsgesetz) the employee while performing his
         employment activities and his contractual duties obtains a personal
         right thereto. If the invention is patentable or admissible to model
         registration utility, the employee has the duty to inform his employer
         of his invention. The employer is entitled - respecting certain time
         limits - to request the transfer of rights to the invention
         indemnifying the employee. Employee-inventions subject to the
         copyright-act (Urheberrechtsgesetz) are not transferable, therefore the
         employer being only entitled to make use of it. According to the

         In the event that the assets, as listed in the annual balance sheet, no
         longer cover half of the share capital and the legal reserves of the
         company, Art. 725 subsection 1 of the Swiss Code of Obligations ("Art.
         725 subsection 1") provides for the board of directors to call a
         general meeting of the shareholders and to propose a financial
         reorganization. Furthermore, Art. 725 subsection 2 of the Swiss Code of
         Obligations ("Art. 725 subsection 2"_) states that if the claims of the
         company's obligees are neither covered if the assets are valued at
         on-going business value nor at liquidation values, the board of
         directors shall notify the judge in order to commence bankruptcy
         proceedings unless obligees of the company subordinate their claims to
         those of all other company obligees to the extent of such insufficient
         coverage.

          As far as IAT AG is concerned, the assets as listed in the annual
          balance sheets of the company have fallen below the limit provided in
          Art. 725 subsection 1. Consequently, in order to comply with the
          provisions of Art. 725 subsection 1. and Art. 725 subsection 2 the
          shareholder and the board of directors have taken and are taking the
          measures they deem appropriate. In particular, the capital of the
          company was increased to

         SFr. 10,000,000 and the present shareholders of IAT AG have provided
         IAT AG with subordinated loans amounting to SFr. 900,000 and DM
         700,000. Furthermore, from the point of view of the shareholders of IAT
         AG, one of the objectives of this present Agreement is to increase the
         capital of IAT AG with the funds which are expected to be provided with
         the proceeds of the Closing and any subsequent financing and thus to
         effect the financial restructuring of the company. IAT AG is of the
         opinion that at Closing it will not be in violation of Art. 725
         subsection 2. Future activities of IAT AG will, however, be dependent
         upon further equity financing as described above.

         C.  IAT GmbH

         The company discloses a negative owners' equity. Since the long-term
         loans from the owners have been subjected to declaration of debt
         subordination under German commercial law, these loans act as equity
         substitutes versus other creditors of the company.

          Agreement as to subordinated loans between IAT AG, Walther Glas GmbH,
          Mr. Sippel and Mr. Suter. The date of this Agreement is August 23,
          1996. According to this Agreement Walther Glas GmbH shall grant to IAT
          AG a subordinated loan amounting to SFr. 1,000,000 and Mr. Sippel
          shall grant to IAT AG a subordinated loan amounting to SFr. 500,000
          (or in the event that the loan granted by Telefutura AG has to be paid
          back prior to the IPO amounting to SFr. 650,000). The loans are to be
          paid back by the company by June 30, 1997. In the event that such
          repayment cannot be effected, specific provisions apply and, in
          particular, Walther Glas GmbH has an option to acquire the shares of
          IAT AG or of Holding held by Mr. Sippel and Mr. Suter. After signing
          of the Stock Purchase Agreement the additional shareholder loan of
          SFr. 500,000 which ought to have been granted to IAT AG by Mr. Sippel
          was granted by Walther Glas GmbH. In return Walther Glas GmbH has
          acquired 500 shares of IAT AG from Mr. Sippel. Mr. Sippel has,
          however, an option to reacquire the equivalent of 500 shares of IAT AG
          in shares of Holdings from Walther Glas GmbH, in the event that this
          last loan amounting to SFr. 500,000 granted by Walther Glas GmbH to
          IAT AG is replaced by a similar loan granted by him at a latter date.

          Investment agreement dated December 19, 1995 between AIG GmbH, IAT AG
          and HIBEG, Bremen. The Agreement provided for the acquisition of 25.1%
          of the capital of IAT GmbH by HIBEG. Furthermore the Agreement lays
          down the general rules for the conduct of the business of IAT GmbH and
          provides for both HIBEG and IAT AG to grant to IAT GmbH subordinated
          shareholders' loans.

         In Switzerland, most employment relations are based on written
         agreements regardless of what position and responsibilities the
         employee has and what kind of work he performs for the employer. Except
         for some of the employment agreement already listed in other
         subsections of Exhibit B, none of these employment contracts provide
         for an unusual period of termination. It must, however, be noted that
         some of the employees of IAT AG work in teams and that the termination
         of some employment relations might, therefore, have an influence on the
         performance of such a team.

         C.  IAT GmbH

         In Germany, most employment relations are based on written agreements
         regardless of what position and responsibilities the employee has and
         what kind of work he performs for the employer. Except for some of the
         employment agreement already listed in other subsections of Exhibit B,
         none of these employment contracts provide for an unusual period of
         termination. It must, however, be noted that some of the employees of
         IAT

         GmbH work in teams and that the termination of some employment
         relations might, therefore, have an influence on the performance of
         such a team.

                                    RECITALS

     WHEREAS, the Company and the Investor are parties to that certain Stock
Purchase Agreement of even date herewith (the "Stock Purchase Agreement");

     WHEREAS, to induce the Investor to invest funds in the Company pursuant to
the Stock Purchase Agreement, the Investor and the Company hereby agree that
this Agreement shall govern the rights of the Investor to cause the Company to
register shares of Common Stock issuable to the Investor upon conversion of
shares of Series A Preferred Stock purchased by the Investor and upon exercise
of a Warrant issued to the Investor pursuant to the Stock Purchase Agreement,
and certain other matters as set forth herein;

     NOW, THEREFORE, in consideration of the mutual promises and covenants set
forth herein, the parties hereto agree as follows:

1.   Registration Rights. The Company covenants and agrees as follows:

     1.1 Definitions. For purposes of this Section 1:

     by the SEC which permits inclusion or incorporation of substantial
     information by reference to other documents filed by the Company with the
     SEC.

          (d) The term "Holder" means any person owning or having the right to
     acquire Registrable Securities or any assignee thereof in accordance with

          (g) The term "register," "registered," and "registration" refer to a

          (h) The term "Registrable Securities" means (i) the Common Stock
     issuable or issued upon conversion of the Preferred Stock or upon exercise
     of the Warrant, (ii) any Common Stock of the Company issued as (or issuable
     upon the conversion or exercise of any warrant, right or other security
     which is issued as) a dividend or other distribution with respect to, or in
     exchange for or in replacement of the shares referenced in (i) above,
     excluding in all cases, however, any Registrable Securities sold by a
     person in a transaction in which his rights under this Section 1 are not
     assigned in accordance with the terms of Section 1.12 hereof.

          (i) The term "SEC" shall mean the Securities and Exchange Commission.

          (j) The term "Warrant" shall mean the warrant to purchase shares of

     1.2 Request for Registration.

     (a) If the Company shall receive at any time after December 31, 1996 a
written request from the Investor that the Company file a registration statement
under the Act covering the registration of at least twenty-five percent (25%) of
the Registrable Securities then held by the Investor, the Company shall:

          (1)  within ten (10) days of the receipt thereof, give written notice,
               in accordance with Section 3.5 hereof, of such request to all
               such other Holders; and

          (2)  file as soon as practicable, and in any event within sixty (60)
               days of the receipt of such request, and use all reasonable
               efforts to cause to become effective as soon as practicable, the
               registration under the Act of all Registrable Securities which
               such Holders request to be registered, subject to the limitations
               of Subsection 1.2(b).

     (b) If the Holders initiating the registration request hereunder
("Initiating Holders") intend to distribute the Registrable Securities covered
by their request by means of an underwriting,





                                       -2-

<PAGE>



they shall so advise the Company as a part of their request made pursuant to
Subsection 1.2(a) and the Company shall include such information in the written
notice referred to in Subsection 1.2(a). The underwriter will be selected by the
Company and shall be acceptable to a majority in interest of the Initiating
Holders. In such event, the right of any Holder to include his Registrable
Securities in such registration shall be conditioned upon such Holder's
participation in such underwriting and the inclusion of such Holder's
Registrable Securities in the underwriting (unless otherwise mutually agreed by
a majority in interest of the Initiating Holders and such Holder) to the extent
provided herein. All Holders proposing to distribute their securities through
such underwriting shall (together with the Company as provided in Subsection
1.4(e)) enter into an underwriting agreement in customary form with the
underwriter or underwriters selected for such underwriting. Notwithstanding any
other provision of this Section 1.2, if the underwriter advises the Initiating
Holders in writing that marketing factors require a limitation of the number of
shares to be underwritten, then the Company shall exclude from such underwriting
(x) first, the maximum number of securities, if any, other than Registrable
Securities, as is necessary to reduce the size of the offering and (y) then the
minimum number of Registrable Securities, pro rata to the extent practicable, on
the basis of the number of Registrable Securities requested to be registered
among the participating holders of Registrable Securities, as is necessary in
the opinion of the managing underwriter(s) to reduce the size of the offering.

     (c) In addition, the Company shall not be obligated to effect, or to take
any action to effect, any registration pursuant to this Section 1.2:

          (i) After the Company has effected two (2) registrations pursuant to
     this Section 1.2, excluding any registrations effected on Form S-3, and
     such registrations have been declared or ordered effective; provided, that
     the Company shall not be obligated to effect more than one registration
     pursuant to this Section 1.2 in any twelve (12) month period;

          (ii) If the Initiating Holders propose to dispose of shares of
     Registrable Securities that may be immediately registered on Form S-3
     pursuant to a request made pursuant to Section 1.12 below; or

          (iii) If the Company delivers to the Initiating Holders an opinion, in
     form and substance acceptable to such Initiating Holders, of counsel
     satisfactory to the Initiating Holders that the Registrable Securities
     requested to be registered by the Initiating Holders may be sold or
     transferred pursuant to Rule 144(k) of the Act.

     1.3 Company Registration. If (but without any obligation to do so) the
Company proposes to register (including for this purpose a registration effected
by the Company for stockholders other than the Holders) any of its stock or
other securities under the Act in connection with the public offering of such
securities (other than a registration relating solely to the sale of securities
to participants in a Company stock plan, a registration relating solely to a
Rule 145 transaction, a





                                       -3-

<PAGE>



registration on any form which does not include substantially the same
information as would be required to be included in a registration statement
covering the sale of the Registrable Securities or a registration in which the
only Common Stock being registered is Common Stock issuable upon conversion of
debt securities which are also being registered), the Company shall, at such
time, promptly give each Holder written notice of such registration. Upon the
written request of each Holder given within twenty (20) days after giving of
such notice by the Company in accordance with Section 3.5, the Company shall,
subject to the provisions of Section 1.8, cause to be registered under the Act
all of the Registrable Securities that each such Holder has requested to be
registered; provided, that the Company shall not be obligated to effect more
than two (2) registrations pursuant to this Section 1.3.

     1.4 Obligations of the Company. Whenever required under this Section 1 to
effect the registration of any Registrable Securities, the Company shall, as
expeditiously as reasonably possible:

          (a) Prepare and file with the SEC a registration statement with
     respect to such Registrable Securities and use its best efforts to cause
     such registration statement to become effective, and keep such registration
     statement effective for a period of up to one hundred twenty (120) days or
     until the distribution contemplated in the Registration Statement has been
     completed, whichever first occurs; provided, however, that such one hundred
     twenty (120) day period shall be extended for a period of time equal to the
     period the Holder refrains from selling any securities included in such
     registration at the request of an underwriter of Common Stock (or other
     securities) of the Company, and provided further that in the case of any
     registration of Registrable Securities on Form S-3 that are intended to be
     offered on a continuous or delayed basis, such one hundred twenty (120) day
     period shall be extended until all such Registrable Securities are sold, if
     applicable rules under the Act governing the obligation to file a
     post-effective amendment permit, in lieu of filing a post-effective
     amendment which (I) includes any prospectus required by Section 10(a)(3) of
     the Act or (II) reflects facts or events representing a material or
     fundamental change in the information set forth in the registration
     statement, the incorporation by reference of information required to be
     included in (I) and (II) above to be contained in periodic reports filed
     pursuant to Section 13 or 15(d) of the 1934 Act in the registration
     statement.

          (b) Prepare and file with the SEC such amendments and supplements to
     such registration statement and the prospectus used in connection with such
     registration statement as, in the opinion of counsel to the Company, may be
     necessary to comply with the provisions of the Act with respect to the
     disposition of all securities covered by such registration statement.

          (c) Furnish to the Holders such numbers of copies of a prospectus,
     including a preliminary prospectus, in conformity with the requirements of
     the Act, and such other documents as they may reasonably request in order
     to facilitate the disposition of Registrable Securities owned by them.






                                       -4-

<PAGE>



          (d) Use its best efforts to register and qualify the securities
     covered by such registration statement under such other securities or Blue
     Sky laws of such jurisdictions as shall be reasonably requested by the
     Holders; provided that the Company shall not be required in connection
     therewith or as a condition thereto to qualify to do business or to file a
     general consent to service of process in any such states or jurisdictions,
     unless the Company is already subject to service in such jurisdiction and
     except as may be required by the Act.

          (e) In the event of any underwritten public offering, enter into and
     perform its obligations under an underwriting agreement, in usual and
     customary form, with the managing underwriter of such offering. Each Holder
     participating in such underwriting shall also enter into and perform its
     obligations under such an agreement.

          (f) Notify each Holder of Registrable Securities covered by such
     registration statement at any time when a prospectus relating thereto is
     required to be delivered under the Act of the happening of any event as a
     result of which the prospectus included in such registration statement, as
     then in effect, includes an untrue statement of a material fact or omits to
     state a material fact required to be stated therein or necessary to make
     the statements therein not misleading in the light of the circumstances
     then existing.

          (g) Cause all such Registrable Securities registered pursuant
     hereunder to be listed on each securities exchange on which similar
     securities issued by the Company are then listed.

          (h) Provide a transfer agent and registrar for all Registrable
     Securities registered pursuant hereunder and a CUSIP number for all such
     Registrable Securities, in each case not later than the effective date of
     such registration.

          (i) Furnish, on the date that such Registrable Securities are
     delivered to the underwriters for sale in connection with the registration
     pursuant to this Section 1, if such Registrable Securities are being sold
     through underwriters, or, if such Registrable Securities are not being sold
     through underwriters, on the date that the registration statement with
     respect to such Registrable Securities becomes effective, (i) an opinion,
     dated such date, of counsel representing the Company for the purposes of
     such registration, in form and substance as is customarily given to
     underwriters in an underwritten public offering, addressed to the
     underwriters, if any, and to the Holders, and (ii) a letter, dated such
     date, from the independent certified public accountants of the Company, in
     form and substance as is customarily given by independent certified public
     accountants to underwriters in an underwritten public offering, addressed
     to the underwriters, if any, and to the Holders.

     1.5 Furnish Information. It shall be a condition precedent to the
obligations of the Company to take any action pursuant to this Section 1 with
respect to the Registrable Securities of any selling Holder that such Holder
shall furnish to the Company such information regarding itself,





                                       -5-

<PAGE>



the Registrable Securities held by it, and the intended method of disposition of
such securities as shall be required to effect the registration of such Holder's
Registrable Securities.

     1.6 Expenses of Demand Registration. All expenses other than underwriting
discounts and commissions incurred in connection with registrations, filings or
qualifications pursuant to Section 1.2, including (without limitation) all
registration, filing and qualification fees, printers' and accounting fees, fees
and disbursements of counsel for the Company and the reasonable fees and
disbursements of one counsel for the selling Holders shall be borne by the
Company.

     1.7 Expenses of Company Registration. The Company shall bear and pay all
expenses incurred in connection with any registration, filing or qualification
of Registrable Securities with respect to the registrations pursuant to Section
1.3 for each Holder, including (without limitation) all registration, filing,
and qualification fees, printers' and accounting fees relating or apportionable
thereto and, for one such registration only, the reasonable fees and
disbursements of one counsel for the selling Holders, but excluding underwriting
discounts and commissions relating to Registrable Securities.

     1.8 Underwriting Requirements. In connection with any offering involving an
underwriting of shares of the Company's capital stock pursuant to Section 1.3,
the Company shall not be required under Section 1.3 to include any of a Holder's
securities in such underwriting unless such Holder accepts the terms of the
underwriting as agreed upon between the Company and the underwriters, and then
only in such quantity as the underwriters determine in their sole discretion
will not jeopardize the success of the offering by the Company. If the total
amount of securities, including Registrable Securities, requested by
stockholders to be included in such offering exceeds the amount of securities
sold other than by the Company that the underwriters determine in their sole
discretion is compatible with the success of the offering, then the Company
shall exclude from such underwriting (x) first, the maximum number of
securities, if any, other than Registrable Securities being sold for the account
of other than the Company, as is necessary to reduce the size of the offering
and (y) then the minimum number of Registrable Securities, pro rata to the
extent practicable, on the basis of the number of Registrable Securities
requested to be registered among the participating holders of Registrable
Securities, as is necessary in the opinion of the managing underwriter(s) to
reduce the size of the offering.

     1.9 Indemnification. In the event any Registrable Securities are included
in a registration statement under this Section 1:

          (a) To the extent permitted by law, the Company will indemnify and
     hold harmless each Holder, the officers and directors of each Holder
     participating in such registration, any underwriter (as defined in the Act)
     for such Holder and each person, if any, who controls such Holder or
     underwriter within the meaning of the Act or the 1934 Act, against any
     losses, claims, damages, or liabilities (joint or several) to which they
     may become subject under the Act, the 1934 Act or state





                                       -6-

<PAGE>



     securities and blue sky laws, or otherwise insofar as such losses, claims,
     damages, or liabilities (or actions in respect thereof) arise out of or are
     based upon any of the following statements, omissions or violations
     (collectively a "Violation"): (i) any untrue statement or alleged untrue
     statement of a material fact contained in such registration statement,
     including any preliminary prospectus or final prospectus contained therein
     or any amendments or supplements thereto and any document filed in
     connection therewith or in connection with any registration or
     qualification under the state securities and blue sky laws, (ii) the
     omission or alleged omission to state therein a material fact required to
     be stated therein, or necessary to make the statements therein not
     misleading, or (iii) any violation or alleged violation by the Company of
     the Act, the 1934 Act or state securities and blue sky laws or any rule or
     regulation promulgated under the Act, the 1934 Act or state securities and
     blue sky laws and the Company will pay to each such Holder, underwriter or
     controlling person, as incurred, any legal or other expenses reasonably
     incurred by them in connection with investigating or defending any such
     loss, claim, damage, liability, or action; provided, however, that the
     Company shall not be liable in any such case for any such loss, claim,
     damage, liability, or action to the extent that it arises out of or is
     based upon a Violation which occurs in reliance upon and in conformity with
     written information furnished expressly for use in connection with such
     registration by any such Holder, underwriter or controlling person;
     provided, however, that the indemnity agreement contained in this
     Subsection 1.9(a) shall not apply to amounts paid in settlement of any such
     loss, claim, damage, liability or action if such settlement is effected
     without the consent of the Company, which consent shall not be unreasonably
     withheld.

          (b) To the extent permitted by law, each selling Holder will indemnify
     and hold harmless the Company, each of its directors, each of its officers
     who has signed the registration statement, each person, if any, who
     controls the Company within the meaning of the Act, any underwriter, any
     other Holder selling securities in such registration statement and any
     controlling person of any such underwriter or other Holder, against any
     losses, claims, damages, or liabilities (joint or several) to which any of
     the foregoing persons may become subject, under the Act, or the 1934 Act,
     insofar as such losses, claims, damages, or liabilities (or actions in
     respect thereto) arise out of or are based upon any Violation, in each case
     to the extent (and only to the extent) that such Violation occurs in
     reliance upon and in conformity with written information furnished by such
     Holder expressly for use in connection with such registration; and each
     such Holder will pay, as incurred, any legal or other expenses reasonably
     incurred by any person intended to be indemnified pursuant to this
     Subsection 1.9(b), in connection with investigating or defending any such
     loss, claim, damage, liability, or action; provided, however, that the
     indemnity agreement contained in this Subsection 1.9(b) shall not apply to
     amounts paid in settlement of any such loss, claim, damage, liability or
     action if such settlement is effected without the consent of the Holder,
     which consent shall not be unreasonably withheld; provided, that, in no
     event shall any selling Holder's liability under this Subsection 1.9(b)
     exceed the proceeds received by such Holder from the offering (net of any
     underwriting discounts and commissions).






                                       -7-

<PAGE>



          (c) Promptly after receipt by an indemnified party under this Section
     1.9 of notice of the commencement of any action (including any governmental
     action), such indemnified party will, if a claim in respect thereof is to
     be made against any indemnifying party under this Section 1.9, deliver to
     the indemnifying party a written notice of the commencement thereof and the
     indemnifying party shall have the right to participate in, and, to the
     extent the indemnifying party so desires, jointly with any other
     indemnifying party similarly noticed, to assume the defense thereof with
     counsel mutually satisfactory to the parties; provided, however, that an
     indemnified party (together with all other indemnified parties which may be
     represented without conflict by one counsel) shall have the right to retain
     one separate counsel, with the fees and expenses to be paid by the
     indemnifying party, if representation of such indemnified party by the
     counsel retained by the indemnifying party would be inappropriate due to
     actual or potential differing interests between such indemnified party and
     any other party represented by such counsel in such proceeding. The failure
     to deliver written notice to the indemnifying party within a reasonable
     time of the commencement of any such action, if prejudicial to its ability
     to defend such action, shall relieve such indemnifying party of its
     liability under this Section 1.9, but (i) only to the extent of the
     liability actually resulting from the failure to deliver written notice and
     (ii) the omission so to deliver written notice to the indemnifying party
     will not relieve it of any liability that it may have to any indemnified
     party otherwise than under this Section 1.9.

          (d) If the indemnification provided for in this Section 1.9 is held by
     a court of competent jurisdiction to be unavailable to an indemnified party
     with respect to any loss, liability, claim, damage, or expense referred to
     therein, then the indemnifying party, in lieu of indemnifying such
     indemnified party hereunder, shall contribute to the amount paid or payable
     by such indemnified party as a result of such loss, liability, claim,
     damage, or expense in such proportion as is appropriate to reflect the
     relative fault of the indemnifying party on the one hand and of the
     indemnified party on the other in connection with the statements or
     omissions that resulted in such loss, liability, claim, damage, or expense
     as well as any other relevant equitable considerations. The relative fault
     of the indemnifying party and of the indemnified party shall be determined
     by reference to, among other things, whether the untrue or alleged untrue
     statement of a material fact or the omission to state a material fact
     relates to information supplied by the indemnifying party or by the
     indemnified party and the parties' relative intent, knowledge, access to
     information, and opportunity to correct or prevent such statement or
     omission; provided, that in no event shall any selling Holder's liability
     under this Section 1.9(d) exceed the proceeds received by such Holder from
     the offering (net of any underwriting discounts and commissions).

          (e) Notwithstanding the foregoing, to the extent that the provisions
     on indemnification and contribution contained in the underwriting agreement
     entered into in connection with the underwritten public offering are in
     conflict with the foregoing provisions, the provisions in the underwriting
     agreement shall control.

          (f) The obligations of the Company and Holders under this Section 1.9
     shall survive the completion of any offering of Registrable Securities in a
     registration statement under this Section 1, and otherwise.

     1.10 Reports Under Securities Exchange Act of 1934. With a view to making
available to the Holders the benefits of Rule 144 promulgated under the Act and
any other rule or regulation of the SEC that may at any time permit a Holder to
sell securities of the Company to the public without registration or pursuant to
a registration on Form S-3, the Company agrees to:

          (a) make and keep public information available, as those terms are
     understood and defined in SEC Rule 144, at all times after ninety (90) days
     after the effective date of the first registration statement filed by the
     Company for the offering of its securities to the general public;

          (b) take such action, including the voluntary registration of its
     Common Stock under Section 12 of the 1934 Act, as is necessary to enable
     the Holders to utilize Form S-3 for the sale of their Registrable
     Securities, such action to be taken as soon as practicable after the end of
     the fiscal year in which the first registration statement filed by the
     Company for the offering of its securities to the general public is
     declared effective;

          (c) file with the SEC in a timely manner all reports and other
     documents required of the Company under the Act and the 1934 Act; and

          (d) furnish to any Holder, so long as the Holder owns any Registrable
     Securities, forthwith upon request (i) a written statement by the Company
     that it has complied with the reporting requirements of SEC Rule 144 (at
     any time after ninety (90) days after the effective date of the first
     registration statement filed by the Company), the Act and the 1934 Act (at
     any time after it has become subject to such reporting requirements), (ii)
     a copy of the most recent annual or quarterly report of the Company and
     such other reports and documents so filed by the Company, and (iii) such
     other information as may be reasonably requested in availing any Holder of
     any rule or regulation of the SEC which permits the selling of any such
     securities without registration or pursuant to such form.

     1.11 Form S-3 Registration. In case the Company shall receive at any time
after the completion of the first registration statement for a public offering
of securities of the Company (other than a registration statement relating
either to the sale of securities to employees of the Company pursuant to a stock
option, stock purchase or similar plan or an SEC Rule 145 transaction), a
written request from the Holders of at least twenty five percent (25%) of the
Registrable Securities then outstanding that the Company effect a registration
on Form S-3 and any related qualification or compliance with respect to all or a
part of the Registrable Securities owned by such Holder or Holders, the Company
will:






                                       -9-

<PAGE>



          (a) promptly give written notice of the proposed registration, and any
     related qualification or compliance, to all other Holders; and

          (b) as soon as practicable, effect such registration and all such
     qualifications and compliances as may be so requested and as would permit
     or facilitate the sale and distribution of all or such portion of such
     Holder's or Holders' Registrable Securities as are specified in such
     request, together with all or such portion of the Registrable Securities of
     any other Holder or Holders joining in such request as are specified in a
     written request given within twenty (20) days after receipt of such written
     notice from the Company; provided, however, that the Company shall not be
     obligated to effect any such registration, qualification or compliance,
     pursuant to this Section 1.11: (1) if Form S-3 is not available for such
     offering by the Holders; (2) if the Holders, together with the holders of
     any other securities of the Company entitled to inclusion in such
     registration, propose to sell Registrable Securities and such other
     securities (if any) at an aggregate price to the public (net of any
     underwriting discounts or commissions) of less than $500,000; (3) if the
     Company has already effected during the previous twelve (12) month period
     two (2) registrations on Form S-3, or any equivalent successor form, for
     the Holders pursuant to this Section 1.11; or (4) in any particular
     jurisdiction in which the Company would be required to qualify to do
     business or to execute a general consent to service of process in effecting
     such registration, qualification or compliance.

          (c) Subject to the foregoing, the Company shall file a registration
     statement covering the Registrable Securities and other securities so
     requested to be registered as soon as practicable after receipt of the
     request or requests of the Holders. All expenses incurred in connection
     with a registration requested pursuant to this Section 1.11, including,
     without limitation, all registration, filing, qualification, printers' and
     accounting fees and the reasonable fees and disbursements of one (1)
     counsel for the selling Holder or Holders and counsel for the Company, but
     excluding any underwriting discounts or commissions associated with
     Registrable Securities, shall be borne by the Company. Registrations
     effected pursuant to this Section 1.11 shall not be counted as
     registrations effected pursuant to Sections 1.2 or 1.3.

          (d) The Company shall not be obligated to effect any registration
     pursuant to this Section 1.11 if the Company delivers to the Holders
     requesting registration under this Section 1.11 an opinion, in form and
     substance acceptable to such Holders, of counsel satisfactory to such
     Holders, that the Registrable Securities so requested to be registered may
     be sold or transferred pursuant to Rule 144(k) under the Act.

     1.12 Assignment of Registration Rights. The rights to cause the Company to
register Registrable Securities pursuant to this Section 1 may be assigned (but
only with all related obligations) by a Holder to any transferee or assignee of
such securities, provided: (a) the Company is, within a reasonable time after
such transfer, furnished with written notice of the name and address of such
transferee or assignee and the securities with respect to which such
registration rights are





                                      -10-

<PAGE>



being assigned; and (b) such transferee or assignee agrees in writing to be
bound by and subject to the terms and conditions of this Agreement.

     2. Covenants of the Company.

     2.1 Financial Statements and Other Information. Except as otherwise set

requirements of the 1934 Act, the Company will deliver to the Investor, for so
long as the Investor holds any shares of the Company's Common Stock:

          (a) as soon as available, but in any event within forty-five (45) days

     of the Company and its subsidiaries for such quarterly period and for the

     and consolidated balance sheets of the Company and its subsidiaries as of
     the end of such quarterly period, setting forth in each case comparisons to

     accepted accounting principles, consistently applied (except for the
     absence of notes and subject to normal year-end adjustments);

          (b) as promptly as possible (but in any event within ninety (90) days)
     after the end of each fiscal year, audited consolidated statements of
     operations and a consolidated statement of cash flows of the Company and

     budget and to the preceding fiscal year, all prepared in accordance with
     United States generally accepted accounting principles, consistently
     applied, and accompanied by an unqualified opinion (except for
     qualifications regarding specified contingent liabilities) of an
     independent accounting firm selected by the Company's Board of Directors;

          (c) prior to the end of each fiscal year, an annual budget (approved
     by the Board of Directors) prepared on a monthly, consolidated basis for
     the Company and its subsidiaries for the succeeding fiscal year (displaying
     detailed anticipated statements of operations and cash flows and balance
     sheets), and promptly upon preparation thereof any other significant
     budgets which the Company prepares and any revisions of such annual or
     other budgets;

          (d) promptly (and in any event within thirty (30) days) after the
     discovery or receipt of notice of any event or circumstance affecting the
     Company or its subsidiaries that is determined in good faith by the Company
     to be material to the Company and its subsidiaries, taken as a whole,
     including but not limited to, the filing of any material litigation against
     the Company or its subsidiaries, acquisitions, mergers, substantial sales
     of assets, significant regulatory or legal developments, the commencement
     of voluntary or involuntary bankruptcy proceedings, natural or





                                      -11-

<PAGE>



     other disasters, significant changes in management or directors, changes in
     auditors, and execution or termination of, or defaults under, material
     contracts, a letter from the Chief Executive Officer or Chief Financial
     Officer of the Company specifying the nature and period of existence
     thereof and, in the case of material litigation, what actions the Company
     and its subsidiaries have taken and propose to take with respect thereto;

          (e) promptly after transmission thereof, copies of all financial
     statements, proxy statements, reports and any other written communications
     which the Company sends to its stockholders generally and copies of all
     registration statements and all regular, special or periodic reports which
     it files with the SEC or with any securities exchange on which any of its
     securities are then listed, and copies of all press releases and other
     statements made available generally by the Company to the public;

          (f) a notice specifying the terms of all sales of the Company's
     securities of which the Company is aware, promptly following the
     consummation thereof; and

          (g) notice of the effectiveness under the Act of the registration
     covering the Company's initial public offering, such notice to be provided
     by telecopier immediately following the SEC's notification to the Company
     of such effectiveness.

     Each of the financial statements referred to in this Section 2.1 will be
true and correct in all material respects and will fairly present the Company's
consolidated financial position and results of operations as of the dates and
for the periods stated therein, subject in the case of the unaudited financial
statements to changes resulting from normal year-end audit adjustments (none of
which would, alone or in the aggregate, be materially adverse to the Company's
financial condition, operating results or business prospects). The Company's
obligation to provide to the Investor the materials described in Subsection (e)
above will continue after the Company is subject to the reporting requirements
of the 1934 Act until the Investor no longer holds any shares of the Company's
Preferred Stock (or Common Stock issued upon conversion thereof or upon exercise
of the Warrant).

     2.2 Designated Director. For so long as the Investor shall hold at least 5%
of the shares of the Company's Preferred Stock, (or at least 5% of the Common
Stock issuable upon conversion of the Preferred Stock or upon exercise of the
Warrant), the Investor shall have the right, but not the obligation, to nominate
as a member of the management slate for election to the Company's Board of
Directors by the stockholders of the Company one (1) person and for so long as
the Investor shall hold at least 10% of the shares of the Company's Preferred
Stock (or at least 10% of the Common Stock issued upon conversion thereof or
upon exercise of the Warrant), the Investor shall have the right, but not the
obligation, to nominate as a member of the management slate for election to the
Company's Board of Directors by the stockholders of the Company two (2) persons,
and the Company agrees to use its best efforts to ensure that such person or
persons are duly elected. Moreover, the





                                      -12-

<PAGE>



Company agrees that one such person shall be elected Co-Chairman of the Board of
Directors of the Company.

     2.3 Inspection of Property. Until the Company is subject to the reporting
requirements of the 1934 Act, the Company will permit the Investor, or any
representatives designated by the Investor, upon reasonable notice and during
normal business hours and such other times as the Investor may reasonably
request, to (i) visit and inspect any of the properties of the Company and its
subsidiaries, (ii) examine the corporate and financial records of the Company
and its subsidiaries and make copies thereof or extracts therefrom, (iii)
discuss the affairs, finances and accounts of the Company and its subsidiaries
with the directors, senior management and independent accountants of the Company
and its subsidiaries, and (iv) consult with and advise the management of the
Company and its subsidiaries as to their affairs, finances and accounts.

     2.4 Positive Covenants. So long as any shares of the Preferred Stock are
outstanding, the Company agrees as follows:

          (a) The Company will retain independent public accountants acceptable
     to the Investor in its discretion who shall certify the Company's financial
     statements at the end of each fiscal year. In the event the services of the
     independent public accountants so selected, or any firm of independent
     public accountants hereafter employed by the Company are terminated, the
     Company will promptly thereafter notify the Investor and will request the
     firm of independent public accountants whose services are terminated to
     deliver to the Investor a letter from such firm setting forth the reasons
     for the termination of their services. In the event of such termination,
     the Company will promptly thereafter engage another firm of independent
     public accountants of recognized national standing. In its notice to the
     Investor the Company shall state whether the change of accountants was
     recommended or approved by the Board of Directors of the Company or any
     committee thereof.

          (b) The Company will retain counsel to the Company acceptable to the
     Investor in its discretion.

          (c) The Company's Board of Directors will meet at least once every
     fiscal quarter.

          (d) The Company shall maintain in full force and effect, fire,
     casualty, workmen's compensation and liability insurance policies, with
     extended coverage, in such amounts and with such coverage as are carried by
     companies in a position similar to that of the Company.

     2.5 Termination of Certain Covenants. The covenants set forth in Sections
2.3 and 2.4 shall terminate and be of no further force or effect upon the
consummation of an initial public offering of shares of Common Stock of the
Company.

                                    EXHIBIT E

              Warrant to Purchase 1,980,000 Shares of Common Stock.



                        WARRANT TO PURCHASE COMMON STOCK

                                       OF

                               IAT HOLDINGS, INC.



     This is to Certify That, FOR VALUE RECEIVED, Vertical Financial Holdings,
or assigns ("Holder"), is entitled to purchase from IAT Holdings, Inc., a
Delaware corporation (the "Company"), following an initial public offering (the
"IPO") of shares of common stock, par value $.01 per share (the "Common Stock")
of the Company and subject to the provisions of this Warrant, 1,980,000 fully
paid, validly issued and nonassessable shares of Common Stock of the Company at
a price per share equal to 130% of the initial public offering price of a share
of Common Stock in the IPO at any time or from time to time during the ten (10)
year period following the closing date of the IPO, but not later than 5:00 p.m.
New York City Time on December 31, 2006. The number of shares of Common Stock to
be received upon the exercise of this Warrant and the price to be paid for each
share of Common Stock may be adjusted from time to time as hereinafter set
forth. The shares of Common Stock deliverable upon such exercise, and as
adjusted from time to time, are hereinafter sometimes referred to as "Warrant
Shares" and the exercise price of a share of Common Stock in effect at any time
and as adjusted from time to time is hereinafter sometimes referred to as the
"Exercise Price."

     (a) EXERCISE OF WARRANT.

          (1) This Warrant may be exercised in whole or in part at any time or
     from time to time during the ten (10) year period following the closing
     date of the IPO, but not later than 5:00 New York City Time on December 31,
     2006 (the "Exercise Period") provided, however, that (i) if either such day
     is a day on which banking institutions in the State of New York are
     authorized by law to close, then on the next succeeding day which shall not
     be such a day, and (ii) in the event of any merger, consolidation or sale
     of substantially all the assets of the Company as an entirety, resulting in
     any distribution to the Company's stockholders, prior to December 31, 2006,
     the Holder shall have the right to exercise this Warrant commencing at such
     time through December 31, 2006 into the kind and amount of shares of stock
     and other securities and property (including cash) receivable by a holder
     of the number of shares of Common Stock into which this Warrant might have





                                       -1-

<PAGE>



     been exercisable immediately prior thereto. This Warrant may be exercised
     by presentation and surrender hereof to the Company at its principal
     office, or at the office of its stock transfer agent, if any, with the
     Purchase Form annexed hereto duly executed and accompanied by payment of
     the Exercise Price for the number of Warrant Shares specified in such form.
     As soon as practicable after each such exercise of the warrants, but not
     later than seven (7) days from the date of such exercise, the Company shall
     issue and deliver to the Holder a certificate or certificate for the
     Warrant Shares issuable upon such exercise, registered in the name of the
     Holder or its designee. If this Warrant should be exercised in part only,
     the Company shall, upon surrender of this Warrant for cancellation, execute
     and deliver a new Warrant evidencing the rights of the Holder thereof to
     purchase the balance of the Warrant Shares purchasable thereunder. Upon
     receipt by the Company of this Warrant at its office, or by the stock
     transfer agent of the Company at its office, in proper form for exercise,
     the Holder shall be deemed to be the holder of record of the shares of
     Common Stock issuable upon such exercise, notwithstanding that the stock
     transfer books of the Company shall then be closed or that certificates
     representing such shares of Common Stock shall not then be physically
     delivered to the Holder.

          (2) At any time during the Exercise Period, the Holder may, at its
     option, exchange this Warrant, in whole or in part (a "Warrant Exchange"),
     into the number of Warrant Shares determined in accordance with this
     Section (a)(2), by surrendering this Warrant at the principal office of the
     Company or at the office of its stock transfer agent, accompanied by a
     notice stating such Holder's intent to effect such exchange, the number of
     Warrant Shares to be exchanged and the date on which the Holder requests
     that such Warrant Exchange occur (the "Notice of Exchange"). The Warrant
     Exchange shall take place on the date specified in the Notice of Exchange
     or, if later, the date the Notice of Exchange is received by the Company
     (the "Exchange Date"). Certificates for the shares issuable upon such
     Warrant Exchange and, if applicable, a new warrant of like tenor evidencing
     the balance of the shares remaining subject to this Warrant, shall be
     issued as of the Exchange Date and delivered to the Holder within seven (7)
     days following the Exchange Date. In connection with any Warrant Exchange,
     this Warrant shall represent the right to subscribe for and acquire the
     number of Warrant Shares (rounded to the next highest integer) equal to (i)
     the number of Warrant Shares specified by the Holder in its Notice of
     Exchange (the "Total Number") less (ii) the number of Warrant Shares equal
     to the quotient obtained by dividing (A) the product of the Total Number
     and the existing Exercise Price by (B) the current market value of a share
     of Common Stock. Current market value shall have the meaning set forth
     Section (c) below, except that for purposes hereof, the date of exercise,
     as used in such Section (c), shall mean the Exchange Date.

     (b) RESERVATION OF SHARES. The Company shall at all times reserve for
issuance and/or delivery upon exercise of this Warrant such number of shares of
its Common Stock as shall be required for issuance and delivery upon exercise of
the Warrants.

     (c) FRACTIONAL SHARES. No fractional shares or script representing
fractional shares shall be issued upon the exercise of this Warrant. With
respect to any fraction of





                                       -2-

<PAGE>



a share called for upon any exercise hereof, the Company shall pay to the Holder
an amount in cash equal to such fraction multiplied by the current market value
of a share, determined as follows:

          (1) If the Common Stock is listed on a national securities exchange or
     admitted to unlisted trading privileges on such exchange or listed for
     trading on the Nasdaq National Market, the current market value shall be
     the last reported sale price of the Common Stock on such exchange or market
     on the last business day prior to the date of exercise of this Warrant or
     if no such sale is made on such day, the average closing bid and asked
     prices for such day on such exchange or market; or

          (2) If the Common Stock is not so listed or admitted to unlisted
     trading privileges, but is traded on the Nasdaq Small Cap Market, the
     current Market Value shall be the average of the closing bid and asked
     prices for such day on such market and if the Common Stock is not so
     traded, the current market value shall be the mean of the last reported bid
     and asked prices reported by the National Quotation Bureau, Inc. on the
     last business day prior to the date of the exercise of this Warrant; or

          (3) If the Common Stock is not so listed or admitted to unlisted
     trading privileges and bid and asked prices are not so reported, the
     current market value shall be an amount, not less than book value thereof
     as at the end of the most recent fiscal year of the Company ending prior to
     the date of the exercise of the Warrant, determined in such reasonable
     manner as may be prescribed by the Board of Directors of the Company.

     (d) EXCHANGE, TRANSFER, ASSIGNMENT OR LOSS OF WARRANT. This Warrant is
exchangeable, without expense, at the option of the Holder, upon presentation
and surrender hereof to the Company or at the office of its stock transfer
agent, if any, for other warrants of different denominations entitling the
holder thereof to purchase in the aggregate the same number of shares of Common
Stock purchasable hereunder. Upon surrender of this Warrant to the Company at
its principal office or at the office of its stock transfer agent, if any, with
the Assignment Form annexed hereto duly executed and funds sufficient to pay any
transfer tax, the Company shall, without charge, execute and deliver a new
Warrant in the name of the assignee named in such instrument of assignment and
this Warrant shall promptly be cancelled. This Warrant may be divided or
combined with other warrants which carry the same rights upon presentation
hereof at the principal office of the Company or at the office of its stock
transfer agent, if any, together with a written notice specifying the names and
denominations in which new Warrants are to be issued and signed by the Holder
hereof. The term "Warrant" as used herein includes any Warrants into which this
Warrant may be divided or exchanged. Upon receipt by the Company of evidence
satisfactory to it of the loss, theft, destruction or mutilation of this
Warrant, and (in the case of loss, theft or destruction) of reasonably
satisfactory indemnification, and upon surrender and cancellation of this
Warrant, if mutilated, the Company will execute and deliver a new Warrant of
like tenor and date. Any such new Warrant





                                       -3-

<PAGE>



executed and delivered shall constitute an additional contractual obligation on
the part of the Company, whether or not this Warrant so lost, stolen, destroyed,
or mutilated shall be at any time enforceable by anyone.

     (e) RIGHTS OF THE HOLDER. The Holder shall not, by virtue hereof, be
entitled to any rights of a shareholder in the Company, either at law or equity,
and the rights of the Holder are limited to those expressed in the Warrant and
are not enforceable against the Company except to the extent set forth herein.

     (f) ANTI-DILUTION PROVISIONS. The Exercise Price in effect at any time and
the number and kind of securities purchasable upon the exercise of the Warrants
shall be subject to adjustment from time to time upon the happening of certain
events as follows:

          (1) In case the Company shall (i) declare a dividend or make a
     distribution on its outstanding shares of Common Stock in shares of Common
     Stock, (ii) subdivide or reclassify its outstanding shares of Common Stock
     into a greater number of shares, or (iii) combine or reclassify its
     outstanding shares of Common Stock into a smaller number of shares, the
     Exercise Price in effect at the time of the record date for such dividend
     or distribution or of the effective date of such subdivision, combination
     or reclassification shall be adjusted so that it shall equal the price
     determined by multiplying the Exercise Price by a fraction, the denominator
     of which shall be the number of shares of Common Stock outstanding after
     giving effect to such action, and the numerator of which shall be the
     number of shares of Common Stock outstanding immediately prior to such
     action. Such adjustment shall be made successively whenever any event
     listed above shall occur.

          (2) In case the Company shall fix a record date for the issuance of
     rights or warrants to all holders of its Common Stock entitling them to
     subscribe for or purchase shares of Common Stock (or securities convertible
     into Common Stock) at a price (the "Subscription Price") (or having a
     conversion price per share) less than the current market price of the
     Common Stock (as defined in Subsection (8) below) on the record date
     mentioned below, or less than the Exercise Price on such record date, the
     Exercise Price shall be adjusted so that the same shall equal the lower of
     (i) the price determined by multiplying the Exercise Price in effect
     immediately prior to the date of such issuance by a fraction, the numerator
     of which shall be the sum of the number of shares of Common Stock
     outstanding on the record date mentioned below and the number of additional
     shares of Common Stock which the aggregate offering price of the total
     number of shares of Common Stock so offered (or the aggregate conversion
     price of the convertible securities so offered) would purchase at such
     current market price per share of the Common Stock, and the denominator of
     which shall be the sum of the number of shares of Common Stock outstanding
     on such





                                       -4-

<PAGE>



     record date and the number of additional shares of Common Stock offered for
     subscription or purchase (or into which the convertible securities so
     offered are convertible) or (ii) in the event the Subscription Price is
     equal to or higher than the current market price but is less than the
     Exercise Price, the price determined by multiplying the Exercise Price in
     effect immediately prior to the date of issuance by a fraction, the
     numerator of which shall be the sum of the number of shares outstanding on
     the record date mentioned below and the number of additional shares of
     Common Stock which the aggregate offering price of the total number of
     shares of Common Stock so offered (or the aggregate conversion price of the
     convertible securities so offered) would purchase at the Exercise Price in
     effect immediately prior to the date of such issuance, and the denominator
     of which shall be the sum of the number of shares of Common Stock
     outstanding on the record date mentioned below and the number of additional
     shares of Common Stock offered for subscription or purchase (or into which
     the convertible securities so offered are convertible). Such adjustment
     shall be made successively whenever such rights or warrants are issued and
     shall become effective immediately after the record date for the
     determination of shareholders entitled to receive such rights or warrants;
     and to the extent that shares of Common Stock are not delivered (or
     securities convertible into Common Stock are not delivered) after the
     expiration of such rights or warrants the Exercise Price shall be
     readjusted to the Exercise Price which would then be in effect had the
     adjustments made upon the issuance of such rights or warrants been made
     upon the basis of delivery of only the number of shares of Common Stock (or
     securities convertible into Common Stock) actually delivered.

          (3) In case the Company shall hereafter distribute to the holders of
     its Common Stock evidences of its indebtedness or assets (excluding cash
     dividends or distributions and dividends or distributions referred to in
     Subsection (1) above) or subscription rights or warrants (excluding those
     referred to in Subsection (2) above), then in each such case the Exercise
     Price in effect thereafter shall be determined by multiplying the Exercise
     Price in effect immediately prior thereto by a fraction, the numerator of
     which shall be the total number of shares of Common Stock outstanding
     multiplied by the current market price per share of Common Stock (as
     defined in Subsection (8) below), less the fair market value (as determined
     by the Company's Board of Directors) of said assets or evidences of
     indebtedness so distributed or of such rights or warrants, and the
     denominator of which shall be the total number of shares of Common Stock
     outstanding multiplied by such current market price per share of Common
     Stock. Such adjustment shall be made successively whenever such a record
     date is fixed. Such adjustment shall be made whenever any such distribution
     is made and shall become effective immediately after the record date for
     the determination of shareholders entitled to receive such distribution.






                                       -5-

<PAGE>



          (4) In case the Company shall issue shares of its Common Stock,
     excluding shares issued (i) in any of the transactions described in
     Subsection (1) above, (ii) upon exercise of options granted to the
     Company's employees under a plan or plans adopted by the Company's Board of
     Directors and approved by its shareholders, if such shares would otherwise
     be included in this Subsection (4), (but only to the extent that the
     aggregate number of shares excluded hereby and issued after the date
     hereof, shall not exceed 5% of the Company's Common Stock outstanding at
     the time of any issuance), (iii) upon exercise of this Warrant (iv) to
     shareholders of any corporation which merges into the Company in proportion
     to their stock holdings of such corporation immediately prior to such
     merger, upon such merger, or (v) issued in a bona fide public offering
     pursuant to a firm commitment underwriting, but only if no adjustment is
     required pursuant to any other specific subsection of this Section (f)
     (without regard to Subsection (9) below) with respect to the transaction
     giving rise to such rights, for a consideration per share (the "Offering
     Price") less than the current market price per share (as defined in
     Subsection (8) below) on the date the Company fixes the offering price of
     such additional shares or less than the Exercise Price, the Exercise Price
     shall be adjusted immediately thereafter so that it shall equal the lower
     of (i) the price determined by multiplying the Exercise Price in effect
     immediately prior thereto by a fraction, the numerator of which shall be
     the sum of the number of shares of Common Stock outstanding immediately
     prior to the issuance of such additional shares and the number of shares of
     Common Stock which the aggregate consideration received (determined as
     provided in Subsection (7) below) for the issuance of such additional
     shares would purchase at such current market price per share of Common
     Stock, and the denominator of which shall be the number of shares of Common
     Stock outstanding immediately after the issuance of such additional shares
     or (ii) in the event the Offering Price is equal to or higher than the
     current market price per share but less than the Exercise Price, the price
     determined by multiplying the Exercise Price in effect immediately prior to
     the date of issuance by a fraction, the numerator of which shall be the
     number of shares of Common Stock outstanding immediately prior to the
     issuance of such additional shares and the number of shares of Common Stock
     which the aggregate consideration received (determined as provided in
     subsection (7) below) for the issuance of such additional shares would
     purchase at the Exercise Price in effect immediately prior to the date of
     such issuance, and the denominator of which shall be the number of shares
     of Common Stock outstanding immediately after the issuance of such
     additional shares. Such adjustment shall be made successively whenever such
     an issuance is made.

          (5) In case the Company shall issue any securities convertible into or
     exchangeable for its Common Stock, excluding securities issued in
     transactions described in Subsections (2) and (3) above, for a
     consideration per share of Common





                                       -6-

<PAGE>



     Stock (the "Conversion Price") initially deliverable upon conversion or
     exchange of such securities (determined as provided in Subsection (7)
     below) less than the current market price per share (as defined in
     Subsection (8) below) in effect immediately prior to the issuance of such
     securities, or less than the Exercise Price, the Exercise Price shall be
     adjusted immediately thereafter so that it shall equal the lower of (i) the
     price determined by multiplying the Exercise Price in effect immediately
     prior thereto by a fraction, the numerator of which shall be the sum of the
     number of shares of Common Stock outstanding immediately prior to the
     issuance of such securities and the number of shares of Common Stock which
     the aggregate consideration received (determined as provided in Subsection
     (7) below) for such securities would purchase at such current market price
     per share of Common Stock, and the denominator of which shall be the sum of
     the number of shares of Common Stock outstanding immediately prior to such
     issuance and the maximum number of shares of Common Stock of the Company
     deliverable upon conversion of or in exchange for such securities at the
     initial conversion or exchange price or rate or (ii) in the event the
     Conversion Price is equal to or higher than the current market price per
     share but less than the Exercise Price, the price determined by multiplying
     the Exercise Price in effect immediately prior to the date of issuance by a
     fraction, the numerator of which shall be the sum of the number of shares
     outstanding immediately prior to the issuance of such securities and the
     number of shares of Common Stock which the aggregate consideration received
     (determined as provided in subsection (7) below) for such securities would
     purchase at the Exercise Price in effect immediately prior to the date of
     such issuance, and the denominator of which shall be the sum of the number
     of shares of Common Stock outstanding immediately prior to the issuance of
     such securities and the maximum number of shares of Common Stock of the
     Company deliverable upon conversion of or in exchange for such securities
     at the initial conversion or exchange price or rate. Such adjustment shall
     be made successively whenever such an issuance is made.

          (6) Whenever the Exercise Price payable upon exercise of each Warrant
     is adjusted pursuant to Subsections (1), (2), (3), (4) and (5) above, the
     number of Shares purchasable upon exercise of this Warrant shall
     simultaneously be adjusted by multiplying the number of Shares initially
     issuable upon exercise of this Warrant by the Exercise Price in effect on
     the date hereof and dividing the product so obtained by the Exercise Price,
     as adjusted.

          (7) For purposes of any computation respecting consideration received
     pursuant to Subsections (4) and (5) above, the following shall apply:

               (A) in the case of the issuance of shares of Common Stock for
          cash, the consideration shall be the amount of such cash, provided
          that in no case





                                       -7-

<PAGE>



          shall any deduction be made for any commissions, discounts or other
          expenses incurred by the Company for any underwriting of the issue or
          otherwise in connection therewith;

               (B) in the case of the issuance of shares of Common Stock for a
          consideration in whole or in part other than cash, the consideration
          other than cash shall be deemed to be the fair market value thereof as
          determined in good faith by the Board of Directors of the Company
          (irrespective of the accounting treatment thereof), whose
          determination shall be conclusive; and

               (C) in the case of the issuance of securities convertible into or
          exchangeable for shares of Common Stock, the aggregate consideration
          received therefor shall be deemed to be the consideration received by
          the Company for the issuance of such securities plus the additional
          minimum consideration, if any, to be received by the Company upon the
          conversion or exchange thereof (the consideration in each case to be
          determined in the same manner as provided in clauses (A) and (B) of
          this Subsection (7)).

          (8) For the purpose of any computation under Subsections (2), (3), (4)
     and (5) above, the current market price per share of Common Stock at any
     date shall be determined in the manner set forth in Section (c) hereof
     except that the current market price per share shall be deemed to be the
     higher of (i) the average of the prices for 30 consecutive business days
     before such date or (ii) the price on the business day immediately
     preceding such date.

          (9) No adjustment in the Exercise Price shall be required unless such
     adjustment would require an increase or decrease of at least five cents
     ($0.05) in such price; provided, however, that any adjustments which by
     reason of this Subsection (9) are not required to be made shall be carried
     forward and taken into account in any subsequent adjustment required to be
     made hereunder. All calculations under this Section (f) shall be made to
     the nearest cent or to the nearest one-hundredth of a share, as the case
     may be. Anything in this Section (f) to the contrary notwithstanding, the
     Company shall be entitled, but shall not be required, to make such changes
     in the Exercise Price, in addition to those required by this Section (f),
     as it shall determine, in its sole discretion, to be advisable in order
     that any dividend or distribution in shares of Common Stock, or any
     subdivision, reclassification or combination of Common Stock, hereafter
     made by the Company shall not result in any Federal Income tax liability to
     the holders of Common Stock or securities convertible into Common Stock
     (including Warrants).






                                       -8-

<PAGE>



          (10) Whenever the Exercise Price is adjusted, as herein provided, the
     Company shall promptly but no later than 10 days after any request for such
     an adjustment by the Holder, cause a notice setting forth the adjusted
     Exercise Price and adjusted number of Shares issuable upon exercise of each
     Warrant, and, if requested, information describing the transactions giving
     rise to such adjustments, to be mailed to the Holders at their last
     addresses appearing in the Warrant Register, and shall cause a certified
     copy thereof to be mailed to its transfer agent, if any. In the event the
     Company does not provide the Holder with such notice and information within
     10 days of a request by the Holder, then notwithstanding the provisions of
     this Section (f), the Exercise Price shall be immediately adjusted to equal
     the lowest Offering Price, Subscription Price or Conversion Price, as
     applicable, since the date of this Warrant, and the number of shares
     issuable upon exercise of this Warrant shall be adjusted accordingly. The
     Company may retain a firm of independent certified public accountants
     selected by the Board of Directors (who may be the regular accountants
     employed by the Company) to make any computation required by this Section
     (f), and a certificate signed by such firm shall be conclusive evidence of
     the correctness of such adjustment.

          (11) In the event that at any time, as a result of an adjustment made
     pursuant to Subsection (1) above, the Holder of this Warrant thereafter
     shall become entitled to receive any shares of the Company, other than
     Common Stock, thereafter the number of such other shares so receivable upon
     exercise of this Warrant shall be subject to adjustment from time to time
     in a manner and on terms as nearly equivalent as practicable to the
     provisions with respect to the Common Stock contained in Subsections (1) to
     (9), inclusive above.

          (12) Irrespective of any adjustments in the Exercise Price or the
     number or kind of shares purchasable upon exercise of this Warrant,
     Warrants theretofore or thereafter issued may continue to express the same
     price and number and kind of shares as are stated in the similar Warrants
     initially issuable pursuant to this Agreement.

     (g) OFFICER'S CERTIFICATE. Whenever the Exercise Price shall be adjusted as
required by the provisions of the foregoing Section, the Company shall forthwith
file in the custody of its Secretary or an Assistant Secretary at its principal
office and with its stock transfer agent, if any, an officer's certificate
showing the adjusted Exercise Price determined as herein provided, setting forth
in reasonable detail the facts requiring such adjustment, including a statement
of the number of additional shares of Common Stock, if any, and such other facts
as shall be necessary to show the reason for and the manner of computing such
adjustment. Each such officer's certificate shall be made available at all
reasonable times for inspection by the holder or any holder of a Warrant





                                       -9-

<PAGE>



executed and delivered pursuant to Section (a) and the Company shall, forthwith
after each such adjustment, mail a copy by certified mail of such certificate to
the Holder or any such holder.

     (h) NOTICES TO WARRANT HOLDERS. So long as this Warrant shall be
outstanding, (i) if the Company shall pay any dividend or make any distribution
upon the Common Stock or (ii) if the Company shall offer to the holders of
Common Stock for subscription or purchase by them any share of any class or any
other rights or (iii) if any capital reorganization of the Company,
reclassification of the capital stock of the Company, consolidation or merger of
the Company with or into another corporation, sale, lease or transfer of all or
substantially all of the property and assets of the Company to another
corporation, or voluntary or involuntary dissolution, liquidation or winding up
of the Company shall be effected, then in any such case, the Company shall cause
to be mailed by certified mail to the Holder, at least fifteen days prior the
date specified in (x) or (y) below, as the case may be, a notice containing a
brief description of the proposed action and stating the date on which (x) a
record is to be taken for the purpose of such dividend, distribution or rights,
or (y) such reclassification, reorganization, consolidation, merger, conveyance,
lease, dissolution, liquidation or winding up is to take place and the date, if
any is to be fixed, as of which the holders of Common Stock or other securities
shall receive cash or other property deliverable upon such reclassification,
reorganization, consolidation, merger, conveyance, dissolution, liquidation or
winding up.

     (i) RECLASSIFICATION, REORGANIZATION OR MERGER. In case of any
reclassification, capital reorganization or other change of outstanding shares
of Common Stock of the Company, or in case of any consolidation or merger of the
Company with or into another corporation (other than a merger with a subsidiary
in which merger the Company is the continuing corporation and which does not
result in any reclassification, capital reorganization or other change of
outstanding shares of Common Stock of the class issuable upon exercise of this
Warrant) or in case of any sale, lease or conveyance to another corporation of
the property of the Company as an entirety, the Company shall, as a condition
precedent to such transaction, cause effective provisions to be made so that the
Holder shall have the right thereafter by exercising this Warrant at any time
prior to the expiration of the Warrant, to purchase the kind and amount of
shares of stock and other securities and property receivable upon such
reclassification, capital reorganization and other change, consolidation,
merger, sale or conveyance by a holder of the number of shares of Common Stock
which might have been purchased upon exercise of this Warrant immediately prior
to such reclassification, change, consolidation, merger, sale or conveyance. Any
such provision shall include provision for adjustments which shall be as nearly
equivalent as may be practicable to the adjustments provided for in this
Warrant. The foregoing provisions of this Section (i) shall similarly apply to
successive reclassifications, capital reorganizations and changes of shares of
Common Stock and to successive consolidations, mergers, sales or conveyances. In
the event that in connection with any such capital reorganization or
reclassification, consolidation, merger, sale or conveyance, additional shares
of Common Stock shall be issued in exchange, conversion, substitution or
payment, in whole or in part,





                                      -10-

for a security of the Company other than Common Stock, any such issue shall be
treated as an issue of Common Stock covered by the provisions of Subsection (1)
of Section (f) hereof.

[Form of opinion of counsel to Holdings





Vertical Financial Holdings
[Address]


Ladies and Gentlemen:

     We have acted as special counsel to IAT Holdings, Inc., a Delaware
corporation ("Holdings"), in connection with the Stock Purchase Agreement dated
as of October __, 1996 (the "Stock Purchase Agreement"), between Holdings, IAT
AG, a corporation organized under the laws of Switzerland, IAT Deutschland GmbH,
a corporation organized under the laws of Germany, Vertical Financial Holdings
(the "Investor") and the stockholders listed on Schedule I to the Stock Purchase
Agreement. This is the opinion contemplated by Section 5.6 of the Stock Purchase
Agreement. All capitalized terms used in this opinion without definition have
the respective meanings given to them in the Stock Purchase Agreement.

     In connection with this opinion, we have examined originals or copies,
certified or otherwise identified to our satisfaction, of (i) the Stock Purchase
Agreement, (ii) the Rights Agreement, (iii) the Marketing Agreement, (iv) the
Warrant (together with the Stock Purchase Agreement, the Rights Agreement and
the Marketing Agreement, the "Transaction Documents"), (v) the Certificate of
Incorporation and (vi) the By-Laws of Holdings. In addition, we have made such
investigations and examined such other documents, including certificates of the
officers of Holdings and of public officials, as we have considered necessary or
appropriate as a basis for this opinion. We have assumed the genuineness of the
signatures on all original documents we received and the conformity to the
original documents of all copies submitted to us as certified, conformed or
photographic copies; as to certificates of public officials, we have assumed
that such certificates have been properly given and are accurate.

     Members of our firm are admitted to the bar of the State of New York. We
express no opinion as to the laws of any other jurisdiction other than (i) the
laws of the State of New York and the General Corporation Law of the State of
Delaware and (ii) the federal laws of the United States of America.






<PAGE>



     Based on the foregoing and subject to the assumptions and qualifications
herein, our opinion is as follows:

     1. Holdings is a corporation duly organized, validly existing and in good
standing under the laws of Delaware and has all requisite corporate power and
authority to carry on its business as now conducted and as proposed to be
conducted. Holdings is duly qualified to transact business, and is in good
standing in each jurisdiction in which the failure so to qualify would have a
material adverse effect on its business or properties.

     2. Holdings has all requisite legal and corporate power to execute and
deliver each of the Transaction Documents and to carry out and perform its
obligations under the terms of each of the Transaction Documents. Each of the
Transaction Documents has been duly authorized, executed and delivered by
Holdings and constitutes the legal, valid and binding obligation of Holdings,
enforceable in accordance with its respective terms, except that (a) such
enforcement may be subject to bankruptcy, insolvency, reorganization, moratorium
or other similar laws now or hereafter in effect relating to creditors' rights,
(b) the remedy of specific performance and injunctive and other forms of
equitable relief may be subject to equitable defenses and to the discretion of
the court before which any proceeding therefor may be brought and (c) any rights
to indemnity may be limited by federal and state securities laws and public
policy considerations. Assuming that each of the Transaction Documents has been
duly authorized, executed and delivered by the Subsidiaries (as defined below)
and assuming that each of the Transaction Documents constitutes the legal, valid
and binding obligation of each of the Subsidiaries under the respective laws of
their jurisdictions, each of the Transaction Documents is enforceable as to each
of such Subsidiaries in accordance with its respective terms, except that (a)
such enforcement may be subject to bankruptcy, insolvency, reorganization,
moratorium or other similar laws now or hereafter in effect relating to
creditors' rights, (b) the remedy of specific performance and injunctive and
other forms of equitable relief may be subject to equitable defenses and to the
discretion of the court before which any proceeding therefor may be brought and
(c) any rights to indemnity may be limited by federal and state securities laws
and public policy considerations.

     3. The authorized capitalization of Holdings consists of 20,000,000 shares
of Common Stock, par value $.01 per share (the "Common Stock"), of which
4,620,000 shares are validly issued and outstanding, and 2,000,000 shares of
Preferred Stock, par value $.01 per share (the "Preferred Stock"), of which
1,980,000 shares have been designated Series A Convertible Preferred Stock.
Prior to the Closing, there were no issued and outstanding shares of Preferred
Stock of Holdings. All of the issued and outstanding shares of Common Stock are
duly and validly authorized and issued, fully paid and non-assessable. Except
for the conversion privileges of the Series A Preferred Stock, the Warrant and
the Non-Management Stockholder Warrant, there are not outstanding any options,
warrants, rights (including conversion or preemptive rights), agreements or
commitments of any kind relating to the issuance, sale or transfer of any
securities of Holdings as to which Holdings is a party.






<PAGE>



None of the outstanding shares of Common Stock or other securities of Holdings
was issued in violation of the Securities Act of 1933, as amended.

     4. Assuming that all of the subsidiaries of Holdings are listed on Schedule
I hereto, to the best of our knowledge Holdings does not own, directly or
indirectly, any capital stock or other equity ownership or proprietary interest
in any other corporation, association, trust, partnership, joint venture or
other entity.

     5. The issuance, sale and delivery of the Series A Preferred Stock which is
being purchased by the Investor pursuant to the Stock Purchase Agreement, the
issuance, sale and delivery of the Warrant and the reservation for issuance of
the Common Stock issuable upon conversion or exercise thereof have been duly
authorized by all required corporate action on the part of Holdings, and when
issued, sold, and delivered in accordance with the terms of the Stock Purchase
Agreement for the consideration expressed therein, will be duly and validly
authorized and issued, fully paid and non-assessable and will be issued in
compliance with all applicable federal securities laws. The Common Stock
issuable upon conversion of the Series A Preferred Stock purchased under the
Stock Purchase Agreement upon issuance in accordance with the terms of the
Certificate of Incorporation and upon exercise of the Warrant, shall be duly and
validly authorized and issued, fully paid, and non-assessable, and issued in
compliance with all applicable federal securities laws. The Series A Preferred
Stock issued pursuant to the Stock Purchase Agreement (and the Common Stock
issuable upon conversion of such Series A Preferred Stock and upon exercise of
the Warrant) will be free and clear from all Encumbrances other than those
created by, or imposed upon, the holders thereof through no action of Holdings.

     6. Neither the execution and delivery of the Transaction Documents nor the
consummation of any or all of the transactions contemplated thereby (a) violates
any provision of the Certificate of Incorporation or By-Laws of Holdings, (b)
violates, or is in conflict with, or constitutes a default (or an event which,
with notice or lapse of time or both, would constitute a default) under, or
results in the termination of, or accelerates the performance required by, or
excuses performance by any person of any of its obligations under, or causes the
acceleration of the maturity of any debt or obligation pursuant to, or results
in the creation or imposition of any Encumbrance upon any property or assets of
Holdings under, any agreement or commitment to which Holdings is a party, or (c)
violates any statute, law, regulation, rule, judgment, decree or order of any
court or other governmental body applicable to Holdings.

     7. No consent, approval, order, or authorization of, or registration,
qualification, designation, declaration or filing with, any United States state
or local governmental authority (other than such as may be required under
applicable securities laws of the various jurisdictions in which the Series A
Preferred Stock will be offered or sold, as to which we express no opinion) on
the part of Holdings is required in connection with the consummation of the
transactions contemplated by the Transaction Documents.






<PAGE>



     8. There is no action, suit, inquiry, proceeding or investigation by or
before any court or governmental body pending or, to the best of our knowledge,
threatened against or involving Holdings or which questions or challenges the
validity of the Transaction Documents or any action taken or to be taken by
Holdings pursuant to the Transaction Documents or in connection with the
transaction contemplated thereby.

     9. To the best of our knowledge, except as provided in Section 1 of the
Rights Agreement, Holdings has not granted or agreed to grant any registration
rights, including piggyback rights, to any person or entity.

     We are furnishing this opinion to you solely for your benefit, and this
opinion is not to be used, circulated, quoted or otherwise referred to for any
other purpose without our prior written consent.

                                Very truly yours,





MIR/WD

                                                                October 23, 1996


Vertical Financial Holdings

Ladies and Gentlemen:

1.   We have acted as counsel to IAT AG, a corporation organized under the laws
     of Switzerland (the "Company" ) in connection with the Stock Purchase
     Agreement dated October 4, 1996 (the "Stock Purchase Agreement"), between
     AIT Holdings, Inc., a Delaware corporation ("Holdings"), the Company, IAT
     Deutschland GmbH Interaktive Mediensysteme, a corporation organized under
     the laws of Germany ("IAT Germany"), the stockholders of Holdings and
     Vertical Financial Holdings (the "Investor"). This is the opinion
     contemplated by Section 5.6 of the Stock Purchase Agreement. All
     capitalized terms used in this opinion without definition have the
     respective meaning given to them in the Stock Purchase Agreement.

2.   In connection with this opinion we have examined a sample copy of (i) the
     Stock Purchase Agreement, (ii) the Rights Agreement, (iii) the Marketing
     Agreement, (iv) the Warrant (together with the Stock Purchase Agreement,
     the Rights Agreement and the Marketing Agreement, the "Transaction
     Agreements") and (v) a copy of the current Certificate of Registration and
     Articles of Association of the Company, both dated September 26, 1996. In
     addition, we have made such investigations and examined such other
     documents, records and papers as we have thought relevant and necessary as
     a basis for our opinions hereinafter expressed.

3.   Assumptions

         For the purposes of this opinion, we have assumed:

          3.1  The genuineness of all signatures;

          3.2  The completeness of and conformity to originals of all documents
               purporting to be copies of originals and the authenticity of all
               documents submitted to us as originals;



                                       -1-

<PAGE>



          3.3  the capacity, power and authority of each of the parties other
               than the Company to enter into and the due execution and delivery
               by such parties other than the Company of the Transaction
               Agreements and the agreements examined by us mentioned in section
               4.6 below;

          3.4  that since October 21, 1996 there have been no amendments to the
               Certificate of Registration and Articles of Associations of the
               Company in the form examined by us;

          3.5  that there are no provisions of the laws of any jurisdiction
               outside Switzerland which would have any implication on the
               opinions we express; 

          3.6  that the Transaction Agreements are legal, valid and enforceable
               against the parties thereto under the laws of the State of New
               York;

          3.7  that, for the purpose of section 4.4(b) hereof and contrary to
               the actual situation, all agreements listed in Schedule 1 are
               governed by Swiss law.

4.   Opinion

     We have made such examination of the laws of Switzerland as currently
     applied by the courts of Switzerland as in our judgment is necessary or
     appropriate for the purposes of this opinion. We do not purport to be
     qualified to pass upon and express no opinion herein as to the laws of any
     other jurisdiction other than those of Switzerland.

     This opinion shall be governed by and construed in accordance with Swiss
     law.

     On the above assumptions and subject to the reservations below, we are of
     the opinion that:

     4.1  The company is a corporation duly incorporated, registered and
          existing under the laws of Switzerland and has all requisite corporate
          power and authority to carry on its business as now conducted and as
          proposed to be conducted. The Company is duly qualified to transact
          business. According to publicly available information in Switzerland
          obtained on October 21, 1996, no legal proceedings have been started
          or threatened for the winding-up, dissolution or reorganization or for
          the appointment of a receiver, administrator or similar officer of the
          Company.

     4.2  The Company has all requisite legal and corporate power to execute and
          deliver the Stock Purchase Agreement and has all requisite legal and
          corporate power to carry out and perform its obligations under the
          terms of such agreement. The Stock Purchase Agreement has been duly
          authorized, (subject to the assumption in section 3.1 above) executed
          and delivered by the Company and, as a whole constitutes the valid and




                                       -2-

<PAGE>



          binding obligation of the Company under the assumption that the Stock
          Purchase Agreement were subject to Swiss law. The choice of New York
          law to govern the Stock Purchase Agreement will be upheld and applied
          by the courts in Switzerland in proceedings in relation to the Stock
          Purchase Agreement, provided that the requested party has sufficiently
          proven to such court the contents of New York law, and further
          provided, that New York law is not incompatible with public policy as
          understood in Switzerland.

     4.3  The authorized capital of the Company consists of 10,000 registered
          shares, par value CHF 1,000.- per share, which are all validly issued
          and outstanding, all of which are held by Holdings to our knowledge
          free and clear of all liens, encumbrances, security interests and,
          subject to the transfer restriction contained in art. 7 of the
          Articles of Association of the Company, free of any restrictions on
          transfer. All of the issued and outstanding registered shares are
          fully paid-in and non-assessable. To our knowledge, with the exception
          of the agreement of August 20/23, 1996 between K.-D. Sippel, R. Suter,
          Walther Glas GmbH and the Company, there are not outstanding any
          options, warrants, rights (including conversion or preemptive rights)
          or commitments of any kind relating to the issuance, sale or transfer
          of any securities of the Company.

     4.4  Neither the execution and delivery of the Stock Purchase Agreement nor
          the consummation of any or all of the transactions contemplated
          thereby (a) violates any provision of the Articles of Association of
          the Company, (b) to our knowledge, violates, or is in conflict with,
          or constitutes a default (or an event which, with notice or lapse of
          time or both, would constitute a default) under, or results in the
          termination of, or accelerates the performance required by, or excuses
          performance by any person of any of its obligation under, or causes
          the acceleration of the maturity of any debt or obligation pursuant
          to, or results in the creation or imposition of any encumbrance upon
          any property or assets of the Company under any agreement or
          commitment to which the Company is a party, or (c) to our knowledge,
          violates any statute, law, regulation, rule, judgment, decree or order
          of any court or other governmental body applicable to the Company.

     4.5  No consent, approval, order or authorization of, or registration,
          qualification, designation, declaration or filing with, any Swiss
          federal, cantonal or municipal governmental authority on the part of
          the Company is required in connection with the consummation of the
          transactions contemplated by the Stock Purchase Agreement. The Company
          has, to our knowledge, complied with all laws, ordinances and
          regulations applicable to it and its business, which the failure to
          comply with would, either individually on the aggregate, have a
          materially adverse effect upon the Company. The Company has obtained
          all Swiss federal, cantonal and municipal governmental licenses and
          permits material to and necessary in the conduct of its





                                       -3-

<PAGE>



          respective business, such licenses and permits are according to
          information received from management in full force and effect, no
          material violations are or have been recorded according to publicly
          available information in respect of any such licenses or permits, and
          no proceeding is pending or, to our knowledge, threatened to revoke or
          limit any thereof.

     4.6  The agreements of the company listed in Schedule I hereto have been
          duly executed by the Company and we are of the opinion that they
          constitute the legal, valid and binding obligation of the Company,
          enforceable in accordance with their terms to the extent they are
          subject to Swiss law.

     4.7  To our knowledge, there is no action, suit, inquiry, proceeding or
          investigation by or before any court or governmental body pending or
          threatened against or involving the Company which questions or
          challenges the validity of the Stock Purchase Agreement or any action
          taken or to be taken by the Company pursuant to the Stock Purchase
          Agreement or in connection with the transactions contemplated thereby,
          and the Company is, with the exception of the proceedings mentioned in
          Exhibit B of the Stock Purchase Agreement, not subject to any
          judgment, order, or decree that may have any material adverse effect
          on its business practices or on its ability to acquire any property or
          conduct any business in any part of the world.

5.   Qualifications

     This opinion is subject to the following qualifications:

     (a)  The enforceability and validity of the Transaction Agreements may be
          limited or affected by bankruptcy, insolvency, liquidation,
          arrangement, reorganization, moratorium or other laws relating to, or
          affecting, creditor' rights generally and by general equitable
          principles.

     (b)  We express no opinion on any statements or warranties of fact set out

          (j) The term "Warrant" shall mean the warrant to purchase shares of

     1.2 Request for Registration.

          (a) If the Company shall receive at any time after December 31, 1996 a
     written request from the Investor that the Company file a registration
     statement under the Act covering the registration of at least twenty-five
     percent (25%) of the Registrable Securities then held by the Investor, the
     Company shall:

          (1)  within ten (10) days of the receipt thereof, give written notice,
               in accordance with Section 3.5 hereof, of such request to all
               such other Holders; and

          (2)  file as soon as practicable, and in any event within sixty (60)
               days of the receipt of such request, and use all reasonable
               efforts to cause to become effective as soon as practicable, the
               registration under the Act of all Registrable Securities which
               such Holders request to be registered, subject to the limitations
               of Subsection 1.2(b).

          (b) If the Holders initiating the registration request hereunder
     ("Initiating Holders") intend to distribute the Registrable Securities
     covered by their request by means of an underwriting, they shall so advise
     the Company as a part of their request made pursuant to Subsection 1.2(a)
     and the Company shall include such information in the written notice
     referred to in Subsection 1.2(a). The underwriter will be selected by the
     Company and shall be acceptable to a majority in interest of the Initiating
     Holders. In such event, the right of any Holder to include his Registrable
     Securities in such registration shall be conditioned upon such Holder's
     participation in such underwriting and the inclusion of such Holder's
     Registrable Securities in the underwriting (unless otherwise mutually
     agreed by a majority in interest of the


                                        2

<PAGE>



     Initiating Holders and such Holder) to the extent provided herein. All
     Holders proposing to distribute their securities through such underwriting
     shall (together with the Company as provided in Subsection 1.4(e)) enter
     into an underwriting agreement in customary form with the underwriter or
     underwriters selected for such underwriting. Notwithstanding any other
     provision of this Section 1.2, if the underwriter advises the Initiating
     Holders in writing that marketing factors require a limitation of the
     number of shares to be underwritten, then the Company shall exclude from
     such underwriting (x) first, the maximum number of securities, if any,
     other than Registrable Securities, as is necessary to reduce the size of
     the offering and (y) then the minimum number of Registrable Securities, pro
     rata to the extent practicable, on the basis of the number of Registrable
     Securities requested to be registered among the participating holders of
     Registrable Securities, as is necessary in the opinion of the managing
     underwriter(s) to reduce the size of the offering.

          (c) In addition, the Company shall not be obligated to effect, or to
     take any action to effect, any registration pursuant to this Section 1.2:

               (i) After the Company has effected two (2) registrations pursuant
          to this Section 1.2, excluding any registrations effected on Form S-3,
          and such registrations have been declared or ordered effective;
          provided, that the Company shall not be obligated to effect more than
          one registration pursuant to this Section 1.2 in any twelve (12) month
          period;

               (ii) If the Initiating Holders propose to dispose of shares of
          Registrable Securities that may be immediately registered on Form S-3
          pursuant to a request made pursuant to Section 1.12 below; or

               (iii) If the Company delivers to the Initiating Holders an
          opinion, in form and substance acceptable to such Initiating Holders,
          of counsel satisfactory to the Initiating Holders that the Registrable
          Securities requested to be registered by the Initiating Holders may be
          sold or transferred pursuant to Rule 144(k) of the Act.

     1.3 Company Registration. If (but without any obligation to do so) the
Company proposes to register (including for this purpose a registration effected
by the Company for stockholders other than the Holders) any of its stock or
other securities under the Act in connection with the public offering of such
securities (other than a registration relating solely to the sale of securities
to participants in a Company stock plan, a registration relating solely to a
Rule 145 transaction, a registration on any form which does not include
substantially the same information as would be required to be included in a
registration statement covering the sale of the Registrable Securities or a
registration in which the only Common Stock being registered is Common Stock
issuable upon conversion of debt securities which are also being registered),
the Company shall, at such time, promptly give each Holder written notice of
such registration. Upon the written request of each Holder given within twenty
(20) days after giving of such notice by the Company in accordance with Section
3.5, the Company shall, subject to the provisions of Section 1.8, cause to be
registered under the Act all of the Registrable Securities that each such Holder
has requested to be registered; provided, that the Company shall not be
obligated to effect more than two (2) registrations pursuant to this Section
1.3.

                                        3

<PAGE>



     1.4 Obligations of the Company. Whenever required under this Section 1 to
effect the registration of any Registrable Securities, the Company shall, as
expeditiously as reasonably possible:

          (a) Prepare and file with the SEC a registration statement with
     respect to such Registrable Securities and use its best efforts to cause
     such registration statement to become effective, and keep such registration
     statement effective for a period of up to one hundred twenty (120) days or
     until the distribution contemplated in the Registration Statement has been
     completed, whichever first occurs; provided, however, that such one hundred
     twenty (120) day period shall be extended for a period of time equal to the
     period the Holder refrains from selling any securities included in such
     registration at the request of an underwriter of Common Stock (or other
     securities) of the Company, and provided further that in the case of any
     registration of Registrable Securities on Form S-3 that are intended to be
     offered on a continuous or delayed basis, such one hundred twenty (120) day
     period shall be extended until all such Registrable Securities are sold, if
     applicable rules under the Act governing the obligation to file a
     post-effective amendment permit, in lieu of filing a post-effective
     amendment which (I) includes any prospectus required by Section 10(a)(3) of
     the Act or (II) reflects facts or events representing a material or
     fundamental change in the information set forth in the registration
     statement, the incorporation by reference of information required to be
     included in (I) and (II) above to be contained in periodic reports filed
     pursuant to Section 13 or 15(d) of the 1934 Act in the registration
     statement.

          (b) Prepare and file with the SEC such amendments and supplements to
     such registration statement and the prospectus used in connection with such
     registration statement as, in the opinion of counsel to the Company, may be
     necessary to comply with the provisions of the Act with respect to the
     disposition of all securities covered by such registration statement.

          (c) Furnish to the Holders such numbers of copies of a prospectus,
     including a preliminary prospectus, in conformity with the requirements of
     the Act, and such other documents as they may reasonably request in order
     to facilitate the disposition of Registrable Securities owned by them.

          (d) Use its best efforts to register and qualify the securities
     covered by such registration statement under such other securities or Blue
     Sky laws of such jurisdictions as shall be reasonably requested by the
     Holders; provided that the Company shall not be required in connection
     therewith or as a condition thereto to qualify to do business or to file a
     general consent to service of process in any such states or jurisdictions,
     unless the Company is already subject to service in such jurisdiction and
     except as may be required by the Act.

          (e) In the event of any underwritten public offering, enter into and
     perform its obligations under an underwriting agreement, in usual and
     customary form, with the managing underwriter of such offering. Each Holder
     participating in such underwriting shall also enter into and perform its
     obligations under such an agreement.



                                        4

<PAGE>



          (f) Notify each Holder of Registrable Securities covered by such
     registration statement at any time when a prospectus relating thereto is
     required to be delivered under the Act of the happening of any event as a
     result of which the prospectus included in such registration statement, as
     then in effect, includes an untrue statement of a material fact or omits to
     state a material fact required to be stated therein or necessary to make
     the statements therein not misleading in the light of the circumstances
     then existing.

          (g) Cause all such Registrable Securities registered pursuant
     hereunder to be listed on each securities exchange on which similar
     securities issued by the Company are then listed.

          (h) Provide a transfer agent and registrar for all Registrable
     Securities registered pursuant hereunder and a CUSIP number for all such
     Registrable Securities, in each case not later than the effective date of
     such registration.

          (i) Furnish, on the date that such Registrable Securities are
     delivered to the underwriters for sale in connection with the registration
     pursuant to this Section 1, if such Registrable Securities are being sold
     through underwriters, or, if such Registrable Securities are not being sold
     through underwriters, on the date that the registration statement with
     respect to such Registrable Securities becomes effective, (i) an opinion,
     dated such date, of counsel representing the Company for the purposes of
     such registration, in form and substance as is customarily given to
     underwriters in an underwritten public offering, addressed to the
     underwriters, if any, and to the Holders, and (ii) a letter, dated such
     date, from the independent certified public accountants of the Company, in
     form and substance as is customarily given by independent certified public
     accountants to underwriters in an underwritten public offering, addressed
     to the underwriters, if any, and to the Holders.

     1.5 Furnish Information. It shall be a condition precedent to the
obligations of the Company to take any action pursuant to this Section 1 with
respect to the Registrable Securities of any selling Holder that such Holder
shall furnish to the Company such information regarding itself, the Registrable
Securities held by it, and the intended method of disposition of such securities
as shall be required to effect the registration of such Holder's Registrable
Securities.

     1.6 Expenses of Demand Registration. All expenses other than underwriting
discounts and commissions incurred in connection with registrations, filings or
qualifications pursuant to Section 1.2, including (without limitation) all
registration, filing and qualification fees, printers' and accounting fees, fees
and disbursements of counsel for the Company and the reasonable fees and
disbursements of one counsel for the selling Holders shall be borne by the
Company.

     1.7 Expenses of Company Registration. The Company shall bear and pay all
expenses incurred in connection with any registration, filing or qualification
of Registrable Securities with respect to the registrations pursuant to Section
1.3 for each Holder, including (without limitation) all registration, filing,
and qualification fees, printers' and accounting fees relating or apportionable
thereto and, for one such registration only, the reasonable fees and


                                        5

<PAGE>



disbursements of one counsel for the selling Holders, but excluding underwriting
discounts and commissions relating to Registrable Securities.

     1.8 Underwriting Requirements. In connection with any offering involving an
underwriting of shares of the Company's capital stock pursuant to Section 1.3,
the Company shall not be required under Section 1.3 to include any of a Holder's
securities in such underwriting unless such Holder accepts the terms of the
underwriting as agreed upon between the Company and the underwriters, and then
only in such quantity as the underwriters determine in their sole discretion
will not jeopardize the success of the offering by the Company. If the total
amount of securities, including Registrable Securities, requested by
stockholders to be included in such offering exceeds the amount of securities
sold other than by the Company that the underwriters determine in their sole
discretion is compatible with the success of the offering, then the Company
shall exclude from such underwriting (x) first, the maximum number of
securities, if any, other than Registrable Securities being sold for the account
of other than the Company, as is necessary to reduce the size of the offering
and (y) then the minimum number of Registrable Securities, pro rata to the
extent practicable, on the basis of the number of Registrable Securities
requested to be registered among the participating holders of Registrable
Securities, as is necessary in the opinion of the managing underwriter(s) to
reduce the size of the offering.

     1.9 Indemnification. In the event any Registrable Securities are included
in a registration statement under this Section 1:

          (a) To the extent permitted by law, the Company will indemnify and
     hold harmless each Holder, the officers and directors of each Holder
     participating in such registration, any underwriter (as defined in the Act)
     for such Holder and each person, if any, who controls such Holder or
     underwriter within the meaning of the Act or the 1934 Act, against any
     losses, claims, damages, or liabilities (joint or several) to which they
     may become subject under the Act, the 1934 Act or state securities and blue
     sky laws, or otherwise insofar as such losses, claims, damages, or
     liabilities (or actions in respect thereof) arise out of or are based upon
     any of the following statements, omissions or violations (collectively a
     "Violation"): (i) any untrue statement or alleged untrue statement of a
     material fact contained in such registration statement, including any
     preliminary prospectus or final prospectus contained therein or any
     amendments or supplements thereto and any document filed in connection
     therewith or in connection with any registration or qualification under the
     state securities and blue sky laws, (ii) the omission or alleged omission
     to state therein a material fact required to be stated therein, or
     necessary to make the statements therein not misleading, or (iii) any
     violation or alleged violation by the Company of the Act, the 1934 Act or
     state securities and blue sky laws or any rule or regulation promulgated
     under the Act, the 1934 Act or state securities and blue sky laws and the
     Company will pay to each such Holder, underwriter or controlling person, as
     incurred, any legal or other expenses reasonably incurred by them in
     connection with investigating or defending any such loss, claim, damage,
     liability, or action; provided, however, that the Company shall not be
     liable in any such case for any such loss, claim, damage, liability, or
     action to the extent that it arises out of or is based upon a Violation
     which occurs in reliance upon and in conformity with written information
     furnished expressly for use in connection with such registration by any
     such Holder, underwriter or controlling person; provided, however, that the
     indemnity agreement contained in


                                        6

<PAGE>



     this Subsection 1.9(a) shall not apply to amounts paid in settlement of any
     such loss, claim, damage, liability or action if such settlement is
     effected without the consent of the Company, which consent shall not be
     unreasonably withheld.

          (b) To the extent permitted by law, each selling Holder will indemnify
     and hold harmless the Company, each of its directors, each of its officers
     who has signed the registration statement, each person, if any, who
     controls the Company within the meaning of the Act, any underwriter, any
     other Holder selling securities in such registration statement and any
     controlling person of any such underwriter or other Holder, against any
     losses, claims, damages, or liabilities (joint or several) to which any of
     the foregoing persons may become subject, under the Act, or the 1934 Act,
     insofar as such losses, claims, damages, or liabilities (or actions in
     respect thereto) arise out of or are based upon any Violation, in each case
     to the extent (and only to the extent) that such Violation occurs in
     reliance upon and in conformity with written information furnished by such
     Holder expressly for use in connection with such registration; and each
     such Holder will pay, as incurred, any legal or other expenses reasonably
     incurred by any person intended to be indemnified pursuant to this
     Subsection 1.9(b), in connection with investigating or defending any such
     loss, claim, damage, liability, or action; provided, however, that the
     indemnity agreement contained in this Subsection 1.9(b) shall not apply to
     amounts paid in settlement of any such loss, claim, damage, liability or
     action if such settlement is effected without the consent of the Holder,
     which consent shall not be unreasonably withheld; provided, that, in no
     event shall any selling Holder's liability under this Subsection 1.9(b)
     exceed the proceeds received by such Holder from the offering (net of any
     underwriting discounts and commissions).

          (c) Promptly after receipt by an indemnified party under this Section
     1.9 of notice of the commencement of any action (including any governmental
     action), such indemnified party will, if a claim in respect thereof is to
     be made against any indemnifying party under this Section 1.9, deliver to
     the indemnifying party a written notice of the commencement thereof and the
     indemnifying party shall have the right to participate in, and, to the
     extent the indemnifying party so desires, jointly with any other
     indemnifying party similarly noticed, to assume the defense thereof with
     counsel mutually satisfactory to the parties; provided, however, that an
     indemnified party (together with all other indemnified parties which may be
     represented without conflict by one counsel) shall have the right to retain
     one separate counsel, with the fees and expenses to be paid by the
     indemnifying party, if representation of such indemnified party by the
     counsel retained by the indemnifying party would be inappropriate due to
     actual or potential differing interests between such indemnified party and
     any other party represented by such counsel in such proceeding. The failure
     to deliver written notice to the indemnifying party within a reasonable
     time of the commencement of any such action, if prejudicial to its ability
     to defend such action, shall relieve such indemnifying party of its
     liability under this Section 1.9, but (i) only to the extent of the
     liability actually resulting from the failure to deliver written notice and
     (ii) the omission so to deliver written notice to the indemnifying party
     will not relieve it of any liability that it may have to any indemnified
     party otherwise than under this Section 1.9.

          (d) If the indemnification provided for in this Section 1.9 is held by
     a court of competent jurisdiction to be unavailable to an indemnified party
     with respect to any loss,


                                        7

<PAGE>



     liability, claim, damage, or expense referred to therein, then the
     indemnifying party, in lieu of indemnifying such indemnified party
     hereunder, shall contribute to the amount paid or payable by such
     indemnified party as a result of such loss, liability, claim, damage, or
     expense in such proportion as is appropriate to reflect the relative fault
     of the indemnifying party on the one hand and of the indemnified party on
     the other in connection with the statements or omissions that resulted in
     such loss, liability, claim, damage, or expense as well as any other
     relevant equitable considerations. The relative fault of the indemnifying
     party and of the indemnified party shall be determined by reference to,
     among other things, whether the untrue or alleged untrue statement of a
     material fact or the omission to state a material fact relates to
     information supplied by the indemnifying party or by the indemnified party
     and the parties' relative intent, knowledge, access to information, and
     opportunity to correct or prevent such statement or omission; provided,
     that in no event shall any selling Holder's liability under this Section
     1.9(d) exceed the proceeds received by such Holder from the offering (net
     of any underwriting discounts and commissions).

          (e) Notwithstanding the foregoing, to the extent that the provisions
     on indemnification and contribution contained in the underwriting agreement
     entered into in connection with the underwritten public offering are in
     conflict with the foregoing provisions, the provisions in the underwriting
     agreement shall control.

          (f) The obligations of the Company and Holders under this Section 1.9
     shall survive the completion of any offering of Registrable Securities in a
     registration statement under this Section 1, and otherwise.

     1.10 Reports Under Securities Exchange Act of 1934. With a view to making
available to the Holders the benefits of Rule 144 promulgated under the Act and
any other rule or regulation of the SEC that may at any time permit a Holder to
sell securities of the Company to the public without registration or pursuant to
a registration on Form S-3, the Company agrees to:

          (a) make and keep public information available, as those terms are
     understood and defined in SEC Rule 144, at all times after ninety (90) days
     after the effective date of the first registration statement filed by the
     Company for the offering of its securities to the general public;

          (b) take such action, including the voluntary registration of its
     Common Stock under Section 12 of the 1934 Act, as is necessary to enable
     the Holders to utilize Form S-3 for the sale of their Registrable
     Securities, such action to be taken as soon as practicable after the end of
     the fiscal year in which the first registration statement filed by the
     Company for the offering of its securities to the general public is
     declared effective;

          (c) file with the SEC in a timely manner all reports and other
     documents required of the Company under the Act and the 1934 Act; and

          (d) furnish to any Holder, so long as the Holder owns any Registrable
     Securities, forthwith upon request (i) a written statement by the Company
     that it has complied with the reporting requirements of SEC Rule 144 (at
     any time after ninety (90) days after the


                                        8

<PAGE>



     effective date of the first registration statement filed by the Company),
     the Act and the 1934 Act (at any time after it has become subject to such
     reporting requirements), (ii) a copy of the most recent annual or quarterly
     report of the Company and such other reports and documents so filed by the
     Company, and (iii) such other information as may be reasonably requested in
     availing any Holder of any rule or regulation of the SEC which permits the
     selling of any such securities without registration or pursuant to such
     form.

     1.11 Form S-3 Registration. In case the Company shall receive at any time
after the completion of the first registration statement for a public offering
of securities of the Company (other than a registration statement relating
either to the sale of securities to employees of the Company pursuant to a stock
option, stock purchase or similar plan or an SEC Rule 145 transaction), a
written request from the Holders of at least twenty five percent (25%) of the
Registrable Securities then outstanding that the Company effect a registration
on Form S-3 and any related qualification or compliance with respect to all or a
part of the Registrable Securities owned by such Holder or Holders, the Company
will:

          (a) promptly give written notice of the proposed registration, and any
     related qualification or compliance, to all other Holders; and

          (b) as soon as practicable, effect such registration and all such
     qualifications and compliances as may be so requested and as would permit
     or facilitate the sale and distribution of all or such portion of such
     Holder's or Holders' Registrable Securities as are specified in such
     request, together with all or such portion of the Registrable Securities of
     any other Holder or Holders joining in such request as are specified in a
     written request given within twenty (20) days after receipt of such written
     notice from the Company; provided, however, that the Company shall not be
     obligated to effect any such registration, qualification or compliance,
     pursuant to this Section 1.11: (1) if Form S-3 is not available for such
     offering by the Holders; (2) if the Holders, together with the holders of
     any other securities of the Company entitled to inclusion in such
     registration, propose to sell Registrable Securities and such other
     securities (if any) at an aggregate price to the public (net of any
     underwriting discounts or commissions) of less than $500,000; (3) if the
     Company has already effected during the previous twelve (12) month period
     two (2) registrations on Form S-3, or any equivalent successor form, for
     the Holders pursuant to this Section 1.11; or (4) in any particular
     jurisdiction in which the Company would be required to qualify to do
     business or to execute a general consent to service of process in effecting
     such registration, qualification or compliance.

          (c) Subject to the foregoing, the Company shall file a registration
     statement covering the Registrable Securities and other securities so
     requested to be registered as soon as practicable after receipt of the
     request or requests of the Holders. All expenses incurred in connection
     with a registration requested pursuant to this Section 1.11, including,
     without limitation, all registration, filing, qualification, printers' and
     accounting fees and the reasonable fees and disbursements of one (1)
     counsel for the selling Holder or Holders and counsel for the Company, but
     excluding any underwriting discounts or commissions associated with
     Registrable

                                        9

<PAGE>



     Securities, shall be borne by the Company. Registrations effected pursuant
     to this Section 1.11 shall not be counted as registrations effected
     pursuant to Sections 1.2 or 1.3.

          (d) The Company shall not be obligated to effect any registration
     pursuant to this Section 1.11 if the Company delivers to the Holders
     requesting registration under this Section 1.11 an opinion, in form and
     substance acceptable to such Holders, of counsel satisfactory to such
     Holders, that the Registrable Securities so requested to be registered may
     be sold or transferred pursuant to Rule 144(k) under the Act.

     1.12 Assignment of Registration Rights. The rights to cause the Company to
register Registrable Securities pursuant to this Section 1 may be assigned (but
only with all related obligations) by a Holder to any transferee or assignee of
such securities, provided: (a) the Company is, within a reasonable time after
such transfer, furnished with written notice of the name and address of such
transferee or assignee and the securities with respect to which such
registration rights are being assigned; and (b) such transferee or assignee
agrees in writing to be bound by and subject to the terms and conditions of this
Agreement.

     2. Covenants of the Company.

     2.1 Financial Statements and Other Information. Except as otherwise set
forth below in this Section 2.1, until the Company is subject to the reporting
requirements of the 1934 Act, the Company will deliver to the Investor, for so
long as the Investor holds any shares of the Company's Common Stock:

          (a) as soon as available, but in any event within forty-five (45) days
     after the end of each quarterly accounting period in each fiscal year,

     and consolidated balance sheets of the Company and its subsidiaries as of
     the end of such quarterly period, setting forth in each case comparisons to
     the annual budget and to the corresponding period in the preceding fiscal
     year, and all such statements will be prepared in accordance with generally
     accepted accounting principles, consistently applied (except for the
     absence of notes and subject to normal year-end adjustments);

          (b) as promptly as possible (but in any event within ninety (90) days)
     after the end of each fiscal year, audited consolidated statements of
     operations and a consolidated statement of cash flows of the Company and
     its subsidiaries for such fiscal year and consolidated balance sheets and

     budget and to the preceding fiscal year, all prepared in accordance with
     United States generally accepted accounting principles, consistently
     applied, and accompanied by an unqualified opinion (except for

<PAGE>



          (c) prior to the end of each fiscal year, an annual budget (approved
     by the Board of Directors) prepared on a monthly, consolidated basis for
     the Company and its subsidiaries for the succeeding fiscal year (displaying
     detailed anticipated statements of operations and cash flows and balance
     sheets), and promptly upon preparation thereof any other significant
     budgets which the Company prepares and any revisions of such annual or
     other budgets;

          (d) promptly (and in any event within thirty (30) days) after the
     discovery or receipt of notice of any event or circumstance affecting the
     Company or its subsidiaries that is determined in good faith by the Company
     to be material to the Company and its subsidiaries, taken as a whole,
     including but not limited to, the filing of any material litigation against
     the Company or its subsidiaries, acquisitions, mergers, substantial sales
     of assets, significant regulatory or legal developments, the commencement
     of voluntary or involuntary bankruptcy proceedings, natural or other
     disasters, significant changes in management or directors, changes in
     auditors, and execution or termination of, or defaults under, material
     contracts, a letter from the Chief Executive Officer or Chief Financial
     Officer of the Company specifying the nature and period of existence
     thereof and, in the case of material litigation, what actions the Company
     and its subsidiaries have taken and propose to take with respect thereto;

          (e) promptly after transmission thereof, copies of all financial
     statements, proxy statements, reports and any other written communications
     which the Company sends to its stockholders generally and copies of all
     registration statements and all regular, special or periodic reports which
     it files with the SEC or with any securities exchange on which any of its
     securities are then listed, and copies of all press releases and other
     statements made available generally by the Company to the public;

          (f) a notice specifying the terms of all sales of the Company's
     securities of which the Company is aware, promptly following the
     consummation thereof; and

          (g) notice of the effectiveness under the Act of the registration
     covering the Company's initial public offering, such notice to be provided
     by telecopier immediately following the SEC's notification to the Company
     of such effectiveness.

     Each of the financial statements referred to in this Section 2.1 will be
true and correct in all material respects and will fairly present the Company's
consolidated financial position and results of operations as of the dates and
for the periods stated therein, subject in the case of the unaudited financial
statements to changes resulting from normal year-end audit adjustments (none of
which would, alone or in the aggregate, be materially adverse to the Company's
financial condition, operating results or business prospects). The Company's
obligation to provide to the Investor the materials described in Subsection (e)
above will continue after the Company is subject to the reporting requirements
of the 1934 Act until the Investor no longer holds any shares of the Company's
Preferred Stock (or Common Stock issued upon conversion thereof or upon exercise
of the Warrant).


                                       11

<PAGE>



     2.2 Designated Director. For so long as the Investor shall hold at least 5%
of the shares of the Company's Preferred Stock, (or at least 5% of the Common
Stock issuable upon conversion of the Preferred Stock or upon exercise of the
Warrant), the Investor shall have the right, but not the obligation, to nominate
as a member of the management slate for election to the Company's Board of
Directors by the stockholders of the Company one (1) person and for so long as
the Investor shall hold at least 10% of the shares of the Company's Preferred
Stock (or at least 10% of the Common Stock issued upon conversion thereof or
upon exercise of the Warrant), the Investor shall have the right, but not the
obligation, to nominate as a member of the management slate for election to the
Company's Board of Directors by the stockholders of the Company two (2) persons,
and the Company agrees to use its best efforts to ensure that such person or
persons are duly elected. Moreover, the Company agrees that one such person
shall be elected Co-Chairman of the Board of Directors of the Company.

     2.3 Inspection of Property. Until the Company is subject to the reporting
requirements of the 1934 Act, the Company will permit the Investor, or any
representatives designated by the Investor, upon reasonable notice and during
normal business hours and such other times as the Investor may reasonably
request, to (i) visit and inspect any of the properties of the Company and its
subsidiaries, (ii) examine the corporate and financial records of the Company
and its subsidiaries and make copies thereof or extracts therefrom, (iii)
discuss the affairs, finances and accounts of the Company and its subsidiaries
with the directors, senior management and independent accountants of the Company
and its subsidiaries, and (iv) consult with and advise the management of the
Company and its subsidiaries as to their affairs, finances and accounts.

     2.4 Positive Covenants. So long as any shares of the Preferred Stock are
outstanding, the Company agrees as follows:

          (a) The Company will retain independent public accountants acceptable
     to the Investor in its discretion who shall certify the Company's financial
     statements at the end of each fiscal year. In the event the services of the
     independent public accountants so selected, or any firm of independent
     public accountants hereafter employed by the Company are terminated, the
     Company will promptly thereafter notify the Investor and will request the
     firm of independent public accountants whose services are terminated to
     deliver to the Investor a letter from such firm setting forth the reasons
     for the termination of their services. In the event of such termination,
     the Company will promptly thereafter engage another firm of independent
     public accountants of recognized national standing. In its notice to the
     Investor the Company shall state whether the change of accountants was
     recommended or approved by the Board of Directors of the Company or any
     committee thereof.

          (b) The Company will retain counsel to the Company acceptable to the
     Investor in its discretion.



                                       12

<PAGE>



          (c) The Company's Board of Directors will meet at least once every
     fiscal quarter.

          (d) The Company shall maintain in full force and effect, fire,
     casualty, workmen's compensation and liability insurance policies, with
     extended coverage, in such amounts and with such coverage as are carried by
     companies in a position similar to that of the Company.

     2.5 Termination of Certain Covenants. The covenants set forth in Sections
2.3 and 2.4 shall terminate and be of no further force or effect upon the
consummation of an initial public offering of shares of Common Stock of the
Company.

     3. Miscellaneous.

     WHEREAS, the Company desires to receive services in connection with (a)
marketing its products worldwide, (b) arranging debt or equity financing for the
Company's products to be purchased by its customers and (c) arranging financing

     NOW, THEREFORE, in consideration of the mutual covenants and agreements,
and other good and valuable consideration, the receipt and adequacy of which is
hereby acknowledged, the parties do hereby covenant and agree, upon the terms
and subject to the conditions hereinafter set forth, as follows:

     Section 1. Retention of General. The Company engages General to assist the
Company in achieving its Objectives, and General accepts such engagement,
subject to the terms and conditions of this Agreement.

          (b) In connection with performing its services, General and the
     Company acknowledge and agree that General may, from time to time, propose
     certain arrangements to the

                                     

<PAGE>



     Company in connection with its Objectives and the Company has no obligation
     to accept such proposals or further obligate itself, and shall only do so
     with prior written approval.

     Section 3. Term. Subject to Section 5 hereof, this Agreement shall be for a

in accordance with its terms.

     Section 10. Governing Law. This Agreement shall be governed by and

      Contract of the communications computer development community (EGKR)

- --------------------------------------------------------------------------------



1.   Preamble

The Deutsche Bundespost Telekom and I.A.T. Deutschland GmbH intend to develop a
communications computer (KR). For this purpose, the contractual parties have
established a "Communications Computer Development Community" (EGKR). The stated
goal of the partners is to obtain the utilization rights to the products
resulting from the development.


2.   Members of the EGKR

The EGKR consists of the following members:

I.A.T. Deutschland GmbH                     Deutsche Bundespost Telekom
                                            FA Siegen, SfE EKOM
Fahrenheitstr. 1                                  Koblenzer Str. 29
2800 Bremen 33                              D-5900 Siegen


3.   Performing the development work

3.1  Goal of the development

The basis for the development of the KR is a systematic "Technical KR
Description" (TBKR), which specifies the relative agreements, a summary
description of the object being developed, the general technical-organizational
requirements, functions, technical documents, operating instructions and
documentation.

The TBKR (Appendix 1 of the contract), which is a component of this contract,
specifies the goal of the development.

Both contractual partners must determine, in writing, that the development has
been completed. Completion is scheduled for 12/31/93.

3.2  Development costs

The members of the EGKR shall bear equal parts of the development costs for the
KR.

Two budgets are drawn up for the development, containing all costs needed for
it. Alternative budget 1 contains the MPEG and RGB-Codec board parts of the
development; alternative budget 2 does not contain these parts. Alternative
budget 2 shall be valid until the interpretation of the technology studies and
the decision whether or not to develop MPEG and RGB Codec boards.

                             

<PAGE>


      Contract of the communications computer development community (EGKR)

- --------------------------------------------------------------------------------



The basis for the decision and the determining criteria for developing the MPEG
and RGB Codec boards are market relevancy and technical feasibility within the
agreed upon budget. If MPEG and RGB Codec boards are developed after the
interpretation of the technology studies, alternative budget 1 shall become
valid. The budgets (Appendix 2 to the contract) shall be finalized with firm
figures, considered maxima, when the contract is concluded.

The total costs shall be determined on the basis of the valid budget. The
Deutsche Bundespost Telekom and I.A.T. GmbH shall each bear 50% of the total
costs so determined. A cost settlement shall be calculated on the basis of the
actual costs incurred by each contractual partner. The cost settlement shall be
made upon completion of the development work.

The amount of the settlement shall be paid by the contractual partner to the
partner which is to receive the settlement within one month from presentation of
the invoice.

Both parties shall assume the duty to minimize costs.

3.3  Change of the goal of the development or of the budget

Changes in the goal of the development (specified in the TBKR) or overrunning
the costs specified in the budget shall be agreed upon by the contractual
parties and set forth in writing.

3.4  Utilization rights

The EGKR shall receive the sole, exclusive, unlimited, irrevocable utilization
rights for all developed components.

The EGKR may sell developed parts. The goal of marketing is the avoidance of
mistakes in development by timely feedback from the market and, if applicable,
refinancing of the development costs by the sale.

A separate agreement shall be made if one of the members of the EGKR wishes to
sell a part of the KR before the development has been completed.

3.5  Division of the development tasks

At the conclusion of the contract, the contractual partners shall specify which
partner shall perform which development work.

      Contract of the communications computer development community (EGKR)

- --------------------------------------------------------------------------------



3.6  Subcontractors

The contractual partners may subcontract parts of their part of the development
work. The issuance of a subcontract shall require written approval from the
other contractual partner, unless it is awarded to a member of the EGKR.

Each contractual partner shall independently conduct the acceptance of the
subcontracts it has issued.

3.7  Confidentiality. Other secrecy. Confidential treatment

The contractual partners shall treat the conclusion of the contract and its
contents, in particular the development goals specified in the TBKR, as strictly
confidential; they may disclose the contents to third parties only to the extent
that this is essential for the performance of their part of the development
work. Each disclosure of contents of the contract shall be notified to the other
contractual partner in writing.

If only partial areas of the development work have to be disclosed,
confidentiality agreements (Appendix 3 to the contract) shall be concluded
covering the purchase of marketable materials/components, or the employment of
free-lance persons.

Subcontractors shall be bound to confidentiality according to the above
mentioned principles.

3.8  Documentation of the stage of development

Each contractual partner shall document its progress in the development work and
keep this record up to date. The continued documentation shall be given to the
other contractual partner every quarter. These documents shall make it possible
to perceive and reconstruct the current stage of development; they shall include
the description of the technology (hard- and software), and the list of the
needed financial and material resources. The documents must make it possible to
compare the estimated versus the actual costs (budget vs. actual expenses).

3.9  ATM components

The ATM components will be developed separately. The Deutsche Bundespost Telekom
will bear the costs of these components alone and shall have the sole,
exclusive, unlimited, irrevocable utilization rights. The Deutsche Bundespost
Telekom will place orders separately for the work needed to adapt the ATM
components to the KR.

      Contract of the communications computer development community (EGKR)

- --------------------------------------------------------------------------------


3.10 Further development of the KR

Further development of the KR, even after the dissolution of the EGKR, shall be
effected by agreement with the other contractual partner.


4.   Amendments and supplements to the contract

Amendments to this contract shall be effective only if they were agreed upon in
writing by a statement signed by the contractual parties. They shall be
designated as "contractual amendment." Contractual amendments shall become valid
components of the contract when they are signed by all contractual parties.

Oral agreements are valid only if they have been confirmed in writing as
indicated above and thus have become components of the contract.


5.   Dissolution and cancellation of the EGKR

The EGKR will be dissolved after the final presentation, the final acceptance of
the KR and the joint statement by both contractual parties that the goal of the
development has been attained. The dissolution of the EGKR shall be set forth in
a written statement, signed by both contractual parties.

Before the dissolution of the EGKR, an agreement shall be concluded concerning
the subsequent utilization of the EGKR utilization rights by the contractual
parties in the form of a licensing agreement, regulating the conveyance, or
exploitation of the utilization rights.

The EGKR may be canceled with 3 month's notice by a contractual partner.
Cancellation shall occur in particular if the contractual parties can no longer
agree on joint action to develop the KR.

In case of cancellation of the EGKR, the results of the development then
existing will be exchanged among the contractual partners in such a way that
each contractual partner has the entire know-how at its disposal. In such a
case, each contractual partner shall receive an unlimited, irrevocable
utilization right for all the components developed by that time. The cost
settlement in such a case shall be based on actual costs incurred by the
contractual partners up to that time.

It is also possible, depending on the results of the technological studies, that
the "integration of the AV/RGB-Demux" will be canceled and therefore not made.

In case of a complete or partial cancellation, work will be paid for pursuant to
actual, proven expenses, with a maximum of the amount indicated in the proposal.

Other rights for regular or extraordinary cancellation shall remain unaffected.


Art. 6 Payment

The agreed upon payment shall cover all the work and expenses incurred by the
contractor itself or subcontractors in the preparation and fulfillment of the
order.

Changes in prices or expenses caused by a change in the work shall be taken into
consideration only if they are set forth in a special written agreement.

If the prices specified in the order represent refunds of expenses, the BAPT
"Preisprufreferat" [price referee] shall determine the prices binding for the
final settlement after all the services have been performed and the prices have
been checked. The prices shall be determined on the basis of the LSP on VO PR
No. 30/53 and any agreements still to be made concerning preliminary price
calculations. Interest to be calculated may be taken into consideration at a
maximum rate of 6% of the capital necessary for the company. The profit is to be
calculated at 3.5% of the assets needed by the company and 1.5% of the costs
incurred, with a maximum of 5% of such costs. If market prices can be proven, or
deduced for individual items, the costs shall not be examined. After the order
has been fulfilled, the vouchers for costs shall be presented to the BAPT price
referee.


Art. 7 Payment

7.1  Payment conditions

Payments shall be made only after all partial services have been accepted.

When the settlement of the order is effected, the claims pursuant to the
contract shall be offset against payments due the EGKR.

Part B: General Conditions of the Contract

Art. 1 Performing the development work

To implement the contract, the contractor shall perform the development work
using the latest state of science and technology and its own knowledge and
experience to achieve the contractually specified result.

The contractor shall develop the component entrusted to it in continuous
consultation with the principal. The duty of the contractor to report shall also
apply to measures which did not lead to a solution pursuant to the order and are
therefore not usable in fulfilling the order.

The principal is authorized to acquaint itself at any time with the progress of
the development work and to view documents and all records on the material,
costs, and labor.

All items and processes developed by the contractor in the performance of the
order shall be considered development results, as well as the records, attempts,
models and prototypes used for this purpose. Upon fulfillment of the contract,
or in case of early cancellation, the development results then existing shall be
appropriately documented and delivered to the principal.

The contractor shall take the principal's written requests for changes into
consideration in performing the development work. If this consideration of
changes jeopardizes the stage of development, or if the expected financial
extent of the development work will thereby be considerably exceeded, the
contractor shall immediately report this to the principal in writing. If cost
overruns are connected with the change, the request for change shall be binding
only after a special, written agreement has been concluded by the contractual
partners concerning the payment for the resulting additional expenses and work
by the contractor.


Art. 2 Subcontractors

Subcontracts shall be subject to prior written approval from the principal.

The contractor shall always request prior written approval from the principal if
it wishes to have third parties outside its company, including free-lance
workers, employed in performing the order, or wishes to acquaint third parties
with portions of the development order.

      Contract of the communications computer development community (EGKR)

- --------------------------------------------------------------------------------



The contractor shall safeguard the principal's interests in awarding
subcontracts. In particular, subcontracts shall be awarded under reasonable
economic conditions from the competitive point of view. Subcontracts shall be
subject to VO PR 30/53. The contractor shall advise its subcontractors thereof
and conclude pertinent agreements with them.

The contractor may not demand a separate, supplementary payment for awarding a
subcontract.

If the contractor entrusts a specific portion of its development work to a third
party, this shall be considered a subcontract. The acquisition by the contractor
of materials or components on the market shall not be considered a subcontract.


Art. 3 Industrial rights

In its development work, the contractor shall use the care customarily used in
its line of business to safeguard the industrial rights of third parties.

If the contractor neglects to use the care required by its line of business, it
shall be liable for all damaging results which the Deutsche Bundespost Telekom
suffers because of the violation of industrial rights by the contractor in its
work.


Art. 4 Technical assistance, obligation to provide supplies

Upon request by the principal, the contractor shall render technical assistance
to third parties which are copying the developed item or applying the developed
process. In case of a difference of opinion between the contractor and the
copying third party, the character and scope of technical assistance shall be
decided by the principal, after both parties have been heard. The personnel and
time involved may not affect the other interests of the contractor.

If, by order of the principal, a third party is making objects needed for other
objects which shall be considered development results pursuant to Art. 1, the
contractor, if it manufactures them and if the principal has no right to copy
them shall, at the principal's request, deliver the items mentioned under Art. 1
to the third party within a reasonable time, at a reasonable price.

Art 5 Confidentiality, confidential treatment

The contractor shall treat the conclusion of the contract, and in particular the
specified development goals, in strict confidence. It may disclose the contents
to third parties only to the extent that this be absolutely necessary for
performing the contract and if the principal has given prior approval. If only
portions of the development work covered by the order need be disclosed, the
"Vertraulichkeitsvereinbarungen" [confidentiality agreements] (Appendix 1)
provided by the Deutsche Bundespost Telekom shall have to be concluded if the
contractor acquires materials and components on the market and employs
free-lance persons, .

The contractor expressly states that it shall treat as strictly confidential the
information it receives during the performance of the contract, in particular
during conversations with other contractors of the Deutsche Bundespost Telekom.

The contractor shall acquaint third parties with the technical data given it by
the contractual partner only with the approval of the principal.

Art. 6 Amendments and supplements to the contract

Amendments to this contract shall be set forth in a statement signed by the
contractual parties. Amendments must be expressly labeled therein "Contractual
amendment." Contractual amendments become valid components of the contract once
they are signed by all contractual parties.

The principal's right to demand changes in the nature of the work on the basis
of Art. 3 VOL/B shall not be affected, but such a demand shall be legally valid
only if it is made in writing, with express reference to Art. 3 VOL/B. If
possible, a change in the agreed upon prices necessitated by the technical
change shall be mutually agreed upon when the request for the technical change
is made.


Art. 7 Disclosures

Disclosures by the contractor of results of work and research shall be subject
to written approval from the principal.


Art. 8 Follow-up orders

The contractor shall not be entitled to receive follow-up orders on the basis of
this contract.


Art. 9 Liability to third parties

The contractor shall not be authorized to represent itself as a representative
of the principal. It shall hold the Deutsche Bundespost Telekom harmless from
claims which, however, may be asserted, pursuant to the principle of the
apparent power of attorney, due to contractual violations.


Art. 10 Site of jurisdiction and performance

Bonn is the site of jurisdiction and performance.

      Contract of the communications computer development community (EGKR)

- --------------------------------------------------------------------------------


1.   Preamble

I.A.T. Deutschland GmbH and the Deutsche Bundespost Telekom established an
"Entwicklungsgemeinschaft Kommunikationsrechner" [communications computer
development community] (EG-KR) on August 12, 1992. The stated goal of the EG-KR
is to produce an intelligent network adapter pursuant to the KR technical
description and to obtain the utilization rights for the products resulting from
this development.

IAT Schweiz AG and the Deutsche Bundespost TELEKOM state and agree that the work
done so far in developing the KR, and the work still to be done or finished in
1994 on the basis of this amendment contract, shall be offset between the two
parties, IAT and Telekom, and then be borne in equal parts by the two parties on
the basis of a new budget, according to the EG-KR agreements. This means that a
cost settlement shall be paid pursuant to section 3.2 of the EG-KR contract.

Because in the meantime the communications computer has been designated as an
"intelligent network adapter," the designation of the development community
shall be changed to "Entwicklungsgemeinschaft Intelligenter Netzadapter"
[intelligent network adapter development community], EG-INA.

All the components of the EG-KR contract of 8/12/92 which are not mentioned in
this amendment contract remain unchanged.

                                    Preamble

The Deutsche Bundespost Telekom and the companies I.A.T, AG and IBM Deutschland
Informationssysteme GmbH have established the "Entwicklungsgemeinschaft
Multimediales Informations- und Kommunikations-System" (EG-MIKS) [multimedia
information and communications system development community] pursuant to a
contract dated 6/8/93, to jointly develop a multimedia information and
communications system (MIKS).

The stated goal of the developing partners is to develop the MIKS as a joint
product and to keep the utilization rights of the functionality of the MIKS as a
total system based on their joint development, separate from the rights to the
jointly developed components.

The developing partners have already jointly developed MIKS version 1 and MIKS
version 2. The development of MIKS version 3 is to be covered by a new contract
for the development community, governed by the stipulations listed below. The
contract covering the establishment of EG-MIKS dated 6/8/93 is thus not
applicable to the development of the MIKS version 3.


                            1. Object of the contract

1.1 Content

The three partners will jointly develop a version 3.0 of the MIKS, as a 2-card
solution (IMT-basis board incl. ISDN piggy-back board, IMT Codec board and
Breakout-Box).

IBM shall produce the technology of the hard- and software of the IMT Basis
board, of the ISDN piggy-back board and of the Breakout Box, which is used to
connect external signal sources.

IAT shall provide the hard- and software needed for the Codec board.

IBM shall manufacture in two steps the MIKS "Kiosk tool," a tool to manufacture
user interfaces for MIKS applications incl. running time environment components
and administrative functions:

1)   MIKS Kiosk tool software development, based on MIKS hardware platform
     version 2.0 on MIKS subsystem version 2.1.

2)   MIKS Kiosk Tool software development based on MIKS hardware platform
     version 3.0 on MIKS subsystem version 3.0.

IAT shall make the MIKS 2.1 subsystem for the hardware platform MIKS version
2.0.

IBM and IAT shall make MIKS version 3.0, including the subsystem software on the
basis of the IMT Board.

                                        2

<PAGE>



Telekom shall assume the necessary project management, the (partial) acceptance,
and the measurements required for the BZT approval and for the conformity tests.
The services described in Appendix 1, itemized for each contributor, corresponds
to the division of labor listed above.

All the work shall be performed pursuant to the "Technische Beschreibung MIKS
Vers. 3.0" [MIKS version 3 technical description] (TB-MIKS) and the "Technische
Beschreibung der IMT Komponenten" [Technical description of the IMT components]
(TB-IMT) attached as Appendix 2 and Appendix 3, being essential components of
the contract. The technical descriptions take precedence over all descriptions
of MIKS version 3 and all its appendices.

All the partners shall collaborate at the level of the highest achievable state
of the art in science and technology, using their own knowledge and experience.

1.2 The MIKS system components

The MIKS consists of the following main components:

- - terminals (T1 to T4)
- - consultant station
- - editing station
- - administration station and
- - remote maintenance station.

The basis performance characteristics and available functions of the main
components of the MIKS versions 2, 3 and 4 (planned) are described in Appendix 4
of the MIKS version 3.0 cooperation contract (MIKS system components).

1.3 Time schedule

By 1/31/95, the contractual partners shall work out the detailed specifications
required for performing the contract pursuant to the technical descriptions, and
a project schedule based thereon. The detailed specifications and project
schedule shall be attached as Appendices 6 and 7 once this contract has been
drawn up.

By 7/15/95, IBM is to have completed the development of 24 functional prototypes
of the IMT Basis Board, the ISDN piggy-back boards and Breakout boxes, and IAT
the development of 24 prototypes IMT Codec boards. By that date, IBM and IAT
shall deliver eight functional prototypes, including all necessary cables, to
each of the other two contractual partners. The intention is to complete the
development, including acceptance and approval pursuant to No. 6 of this
contract, by 9/30/95.


                                        3

<PAGE>



1.4 Imponderables, changes of the technical design

Observance of the tight schedule for developing MIKS version 3.0 on the basis of
the IMT boards is based on careful estimates by the EG-MIKS partners.

But because of unforeseeable events (e.g. advances in technology) it may become
necessary to change the schedule as to time and/or work done. In such case, the
technical descriptions of IMT and MIKS which together form the technically
binding basis for the development, will have to be adapted.

Such a change requires the joint decision of all the partners to this
cooperation contract.

                                        4

<PAGE>



                                   2. Expenses

The amounts indicated in the list of services for the cooperation contract
(appendix 1), which is a component of this contract, represent the maxima costs
to be offset. These maxima may be changed only for inevitable cost overruns
which could not be foreseen when the contract was concluded, and only by
agreement of all the project partners.

Each partner shall bear one third of the expenses.

From the beginning of the development until completion, acceptance and BZT
approval, the funds spent by participating project partners shall be reported
monthly to SfE EKOM (project management) and carried forward by the latter.

A weekly telephone conference, under the leadership of SfE EKOM, by all the
companies participating in the project is recommended to make it possible to
monitor the progress of the project and make any necessary adjustments.

The expenses incurred by each project partner will be added up when the project
is completed and settled in such a way (full settlement) that each project
partner (IBM, IAT, Telekom) shall bear an equal amount of the expenses (share 
of the funding).

Undocumented expenses cannot be included in this cost settlement.

The parts of the platform needed for the MIKS (IBM PC, OS/2 operating system, H.
320 software Codec and builder/2) are not covered by this contract. Unless they
are provided free of charge pursuant to No. 3.1 (existing rights), they shall be
acquired, along with the utilization rights, from the cooperating partners at 
market prices.
The purchase prices listed in Appendix 9 are estimates based on current
quotations.

On the following occasions, advance payments (installments of the expected full
settlement payments) shall be made by Telekom to IAT and IBM, against proof of
work done and presentation of invoices:

shall maintain confidentiality on received information in the same manner as for
its own confidential information.

This obligation also applies to partners' associated companies; but they are not
considered third parties in the sense of this contract. The following are
understood to be associated companies:

- -    Companies in which the business of the cooperating partner, or another
     associated business, has a direct or indirect majority participation or on
     which it can directly or indirectly exercise a dominating influence.

- -    Companies which receive a direct or indirect majority participation in the
     business of the cooperating partner or which can directly or indirectly
     exercise a dominating influence on it.

Information which must be kept confidential shall be labeled "(name of the
owner) Confidential." If information which should be kept confidential is not so
labeled, or was so indicated only orally, it shall be labeled confidential when
this becomes known and this shall be confirmed to the recipient immediately in
writing.

The following information need not be treated as confidential:

Information:

- -    Owned by the cooperating partners before the beginning of the negotiations
     on the EG-MIKS,

- -    Developed, or to be developed, independently of information received from
     the other cooperating partners,

- -    Publicly available,


                                        8

<PAGE>



- -    Received, or to be received, legally by the cooperating partners from third
     parties without obligation to secrecy,

- -    Released by other cooperating partners.

Each partner is free to use the "knowledge remaining" of the confidential
information of the other cooperating partners for all purposes, but shall
prevent access to it by third parties during the agreed upon period. The receipt
of confidential information does not obligate the recipient to restrict the
place and area of employment of its employees in any way. "Knowledge remaining"
is understood to mean information which is not written down but which might be
remembered by employees who participated in conversations. It shall not create a
right to a license for patents and similar industrial rights and copyrighted
material.

The obligation to maintain confidentiality persists after the contract is
terminated, but not for more than five years after transmittal of the
information in question.


            6. Acceptance and guarantee of the joint development work

If the development stages have concluded with the making of the prototype
boards, serial boards and MIKS version 3.0, the developing partner reports this
to the others and all parties agree on a date for presentation of the prototype
and of other results of the development. A written acceptance report shall be
issued on this presentation, containing the test findings and results. The
results of the development shall be measured by criteria specified for the
detailed specifications and the technical descriptions. 

The examination and test routines are defined for this purpose in the detailed
specifications. The other partners shall acknowledge the service rendered on the
basis of the reports on successful tests.

The developing partners shall warranty:

- -    observance of the accepted rules of technology

- -    quality of the materials

- -    observance of the specifications pursuant to MIKS and IMT technical
     descriptions

Warranty claims shall cover the elimination of any existing defects, plus
transportation and incidental costs. The statute of limitations on them runs out
6 months after acceptance. If improvement work is necessary after the warranty
period, the developing partner shall perform it against appropriate payment.


                                  7. Liability


                                        9

<PAGE>



The partners assume mutual liability for indirect personal and material damage,
to the extent that they are responsible for it. They shall be responsible for
intentional acts and gross negligence by management personnel. Liability for
lost income, lost savings, losses due to claims by third parties and loss of
data and other consequential damages is excluded. Also excluded is joint
liability of the cooperating partners for the violation of the rights of third
parties represented by knowledge, results and documents provided by a
contractual partner pursuant to this contract.


                           8. Duration of the contract

This cooperation contract is concluded definitively from the date it is signed
by all three partners until 12/31/95 (availability of MIKS version 3 for
marketing). If the work is not completed by that date, this contract shall be
automatically extended until final completion, but not by more than 6 months.
The results of the work available at that time shall be placed at the disposal
of all the partners.

The utilization and exploitation rights granted pursuant to this cooperation
contract and the limitations of liability and duty to confidentiality persist
after the termination of the contract.

If the scheduled work is not completed by the time the contract is terminated,
the following shall apply:

The rights granted pursuant to No. 3.2 shall cover the results of the work on
hand when the contract is terminated. Each cooperating partner may develop the
results further until they are ready for mass production, or order third parties
to do, and shall be authorized, without restriction, to internally use, sell,
alter, in particular process and modify and continue to develop individual
results of jointly developed work and the total system based on the joint
development. The results of the work shall be fully documented and immediately
given to the other partners, including the source code which has not yet been
deposited by then.


                          9. Deposit of the source code

The partner developing the software shall deposit, with a German notary public
of its choice, a copy of the source code of the software components defined and
jointly financed pursuant to this contract. The name and address of this notary
public shall be reported in writing to the cooperating partners when the deposit
is made.

The code shall be filed, exclusively and irrevocably in favor of the cooperating
partners, in printed and machine readable form.

The products to be filed shall consist of the following components (hereinafter
jointly referred to as "products"):

                                       10

<PAGE>



- -    Copies of all source codes developed and their instructions and support
     documentation, unless they are generally available standard products,

- -    Copies of the tools needed to develop, support and maintain the software,
     and the relative documents,

- -    Copies of all design documents on which the software is based.

The software shall be deposited as soon there is a stable code.

All the deposited products shall be handed over to a cooperating partner who
demands them, if

- -    a bankruptcy or settlement proceeding is requested on the assets of one of
     the cooperating partners which is developing the software, or if such a
     partner becomes insolvent,

- -    one of the cooperating partners which is developing the software gives up
     his business activity, or suffers a financial collapse,

- -    one of the cooperating partners which is developing the software does not
     meet its contractual warranty and maintenance obligations to customers of
     the other cooperating partners (delay, non-performance). The proof thereof
     shall be accepted if the demanding cooperating partner can submit pertinent
     customer correspondence,

- -    a cooperating partner developing the software is not willing, in spite of
     request, to perform maintenance work under the general conditions it has
     offered, or ceases to offer maintenance service.

Each cooperating partner has the right to test the deposited products for
completeness and usefulness, at its own expense.

Each cooperating partner bears the cost of its deposit.


                                  10. Royalties

The expenses incurred in developing the MIKS 3.0 and the necessary hard- and
software pursuant to No. 2, second paragraph, are to be made up by the
collection of royalties. For this purpose, each developing partner shall pay to
the cooperating community a royalty of DM 3,000 for each main component it has
used or sold, and nine percent of the sales per part used outside the MIKS
(derivative product), until the joint development costs have been covered (list
of services, Appendix 1). These payment obligations cease when the amount of the
joint development costs has been attained. Each partner is entitled to one third
of the royalties. The share of the royalties per main component and part /
derivative product shall be transferred quarterly, automatically on the last

                                       11

<PAGE>



payment date, to the contractual partners, with the amounts for the main
components and parts listed separately.

The accounts into which the royalties are to be paid are listed in Appendix 8
(to be sent).

The prototype boards created during the development work shall not be subject to
payment of royalties.

The main components are the terminals in versions T1 to T4, the consultant,
editing, administration, and remote maintenance piggy-backs. The functions of
the administration and/or remote maintenance station may be integrated into the
editing station. No additional license fee shall be necessary if this is done.

As of today, parts are the IMT Boards and the Breakout box listed in the table.

- --------------------------------------------------------------------------------
</TABLE>

The amount of the royalty for each main component or part may subsequently be
adjusted among the cooperating partners to current needs, by mutual agreement,
based on market conditions (in particular with a view to the derivation and
possible development of additional marketable products on the basis of the IMT
board).

The software code provided by IAT and Telekom under OS/2 for MIKS shall be
calculated as a sublicense at market price at the time of the sale of the codec
board.

The ISDN software provided by IBM under OS/2 for MIKS for the ISDN piggy-back
board will be calculated as sublicense, at regular market price, when the basis
board and/or Codec board is sold.


                                  11. Delivery

It is planned that, upon conclusion of the IMT board development by IBM and IAT,
IBM will assume the coordination for the production of the IMT boards (basis
board, ISDN piggy-back board

                                       12

<PAGE>



and Codec board) and for the assembly, test or customer specific adjustments of
the MIKS by order of the cooperating community.

For financial reasons, the contractual partners may decide to place orders for
mass production of the boards to other board manufacturers as well as to the
partners responsible for developing the IMT boards (IAT and IBM), if assurance
is given that the IBM quality standard, including ISO 9001, will be observed.
Suitable procedures will be specified in time for the provision (production and
administration) of the required MIKS software (subsystem software and kiosk
tool) and the documentation.


                          12. Concluding specifications

Changes and supplements to this cooperation contract must be set forth in
writing.

This contract is subject to the laws of the federal republic of Germany. The
contractual law on the UN agreement of 4/11/80 governing contracts on
international sales of merchandise (UNCITRAL) shall not be applicable.

this contract, to the legally permissible extent.

If one stipulation is invalid, or if this contract has gaps, this shall not
affect the validity of the remaining stipulations. The invalid stipulation shall
be considered to have been replaced by one which comes closest to the original
financial meaning and purpose. In case of gaps, a stipulation shall be
considered agreed upon which corresponds to the original meaning and purpose of
this contract.

1.......................................................................FOREWORD

IAT, together with DT, has developed a codec, the control and compression
algorithms of which function in a completely software-oriented manner. This
creates the greatest possible independence of licenses and chips of third
parties. Furthermore, it guarantees the possibility of rapid adaptation to
future developments in the sector of digital compression and data transfer
protocols. With this general cooperation agreement, the partners agree to the
further development and refinement of the codec board, which is currently a
prototype. The services agreed to according to this agreement are not of
significance for marketing of the codec board as such, but rather represent the
obligations taken on by IAT and DT within the scope of the "MIKS" cooperation
agreement (decisive development of the MIKS codec board).

The work sections described in Section 2 (Object of the Agreement) are the total
amount of work services which IAT and DT intend to jointly achieve in accordance
with this agreement, and therefore during the period of this agreement as
defined in Section 12 (Duration of the Agreement). Each work section is followed
by a "transfer and information phase." The concrete division of labor between
the parties to the agreement with regard to the services described in the
individual work sections is described below, by means of the distinction between
Types A, B, and C:

1.1  Work section(s) Type "A"

Work sections defined as Type "A" are those for which it has already been
decided upon conclusion of the agreement that they will be carried out by IAT as
the responsible partner.

1.2  Work section(s) Type "B"

Work sections defined as Type "B" are characterized in that it has not yet been
clearly determined, at the time of conclusion of the agreement, which party to
the agreement is to carry out the service defined in the work section, either
entirely or at least in a leading and primary capacity. These work sections are
characterized in that a study or concept phase precedes the beginning of the
actual development work. In this phase, the work necessary for achieving the
required results is to be recognized, defined, and conceptionally prepared and
described in detailed specifications, so that a binding decision can be reached
about which party to the agreement is to perform the work for this work section
(entirely or in part), taking into consideration the external circumstances
(time frame, costs, other advantages and disadvantages). The decision about this
must be reached by agreement between the partners. The party to the agreement
not entrusted with the development of the tasks of the work section is free to
participate by "accompanying the development" with its own resources, so that a
know-how transfer from the developing partner to the accompanying partner is
ensured. It must be assured that any delays which might result from the know-how
transfer do not significantly influence adherence to the schedule, and that the
developing partner does not incur any additional costs as a result.

IAT/Deutsche Telekom Software Codec on the Basis of the Texas Instruments
Parallel Processor TMS320C8x
- --------------------------------------------------------------------------------


1.3  Work section(s) Type "C"

Work sections defined as Type "C" are those which are clearly to be carried out
by DT as the responsible partner. For reasons of confidentiality, DT will
commission only its software development center in Berlin and the company
Multimedia Software GmbH Dresden, which is part of the DT group, to carry out
work within the framework of this agreement. Commissioning of any other DT
divisions requires the prior approval of IAT.

2.   Object of the Agreement

The technically binding basis of all the development services described in this
section is the "Technical Description of the IMT codec card (TB codec),"
particularly Revisions B and C of the codec board, which is an integral part of
this agreement. For the meanings of the technical terms and abbreviations used
in this agreement, reference is also made to the TB codec.

2.1  Work section 1, Optimization of the H.320 MVP Codec, Type "A"

Optimization of the H.320-MVP codec, including the codec hardware for Rev.
3.0/40 MHz. This includes the H.320 standards. It also includes the H.320-API
with drivers as well as the "Tiny Application" (for demos). The Tiny Application
is based on the H.320-API and runs under the operating system Windows 3.x.

2.2  Work section 2, Integration of JPEG Codec and H.320, Type "B"

Within the scope of this work section, it is supposed to become possible to
operate H.320 and JPEG code simultaneously, on the MVP (under the Multi Tasking
Executive). Starting on 10/16/95, there will be a one-month study phase by IAT.
Subsequently, a description of the service to be performed can be issued.

2.3  Work section 3, Integration of MPEG1 Decoder and H.320, Type "B"

Within the scope of this work section, it is supposed to become possible to
operate H.320 and MPEG decoder simultaneously, on the MVP (under the Multi
Tasking Executive). Starting on 10/16/95, there will be a two-month study phase
by IAT. Subsequently, a description of the service to be performed can be
issued.

2.4  Work section 4, MVP Codec for MFKS, Type "A"

In this work section, the H.320-API as well as the necessary drivers for use of
the MVP code in MFKS under Windows are supposed to be written.

Parallel Processor TMS320C8x
- --------------------------------------------------------------------------------



2.5  Work section 5, MPEG1 Decoder, Type "B"

The software for MPEG1 encoding, which is being acquired as a license from TI,
is supposed to be implemented on the MVP processor for image coding according to
the ISO standard MPEG-1, without additional external modules. Since a very large
amount of computer time is required for MPEG coding, this function is allowed to
use the full capacity of the MVP exclusively. Starting on 10/15/95, a one-month
study phase by IAT will follow. This software (available as a source code) will
be included if the evaluation of the study is positive.

2.6  Work section 6, Expansion of H.320 multi-point capable, Type "A"

The multi-point capability of the MVP codec is to be developed according to the
H.320 recommendation.

2.7  Work section 7, MPEG2 Decoder, Type "C"

It is agreed that a study will be drawn up by DT concerning the potential
possibilities of the implementation of MPEG2 on the MVP chip. The study and the
subsequent implementation of the results found in the study are the object of
this work section.


3.   Prices, Responsibility for Costs

The parties to the agreement agree that an hourly rate of DM 200 (two hundred)
per hour will be billed for the work to be performed within the scope of this
agreement.

DT (SfE EKOM, Siegen) will take on any project management tasks within the scope
of this agreement, and will carry out the approval tests required at the end of
each work section in institutions belonging to Telekom, suitable for such
approval tests.

The amounts listed below represent the maximum limit of costs to be billed. This
maximum limit can only be amended for unavoidable additional costs which could
not be foreseen at the time the agreement was concluded, and only with the
agreement of both partners (see also Section 8, Demonstration of the Time/Amount
Framework). The only exception is costs which are caused by the institutions
commissioned for the approval tests.

</TABLE>


For the Type "B" work sections, both parties to the agreement can each make a
detailed offer, no later than up to the time of a decision concerning carrying
out the development work, in which the costs and the time required for
completing the work must be indicated in binding manner. For finalization of the
Type "A" or "C" work sections, it is sufficient if the partner who is scheduled
to perform the work submits an offer.

A decision about commissioning the development work will be sent to the
developing partner by SfE EKOM, in writing, in the form of an order, so that the
partner can submit a bill for its costs in accordance with the offer and in
accordance with Section 5 (Payment Terms).

Per work section, a cost equalization will be made after completion of the
development work, in that each party to the agreement will pay half of the total
costs incurred within the scope of the agreement, in the final analysis, and
within the framework of the maximum limits indicated above.

The resources expended (human resources, hardware and software expenses) will be
cumulatively documented from the start of development to final completion and
approval.

Non-documented costs cannot be included in the cost equalization.

The costs for their own internal test environments will be paid by the partners
themselves, in each instance.

Any hardware or software costs for prototypes, etc., will be included in the
cost equalization.

If costs are incurred for the know-how transfer from the developing partner to
the accompanying partner, these are to be paid for by the accompanying partner,
upon documentation and by a separate order and billing of the developing
partner. In this case, the uniform hourly billing rate of DM 200 (two hundred)
per hour, which has been agreed to for the agreement as a whole, will apply.

6.   Utilization Rights, Intellectual Property Rights

The rights and obligations with regard to use of the MVP and the software made
available by TI, which are derived from the bilateral agreement between Texas
Instruments and IAT, are transferred to DT to their full extent.

Both parties to the agreement receive the irrevocable, unlimited, exclusive,
free-of-charge and transferable right to utilize all the results achieved within
the scope of carrying out this agreement, without restrictions. The parties to
the agreement also have the right to reproduce and change the results, as well
as the right to grant others a utilization right (sale of licenses).

The sale and/or transfer of the entire utilization rights to third parties is
only possible with the written approval of the other partner.

<PAGE>

General Cooperation Agreement concerning Joint Further Development of the
IAT/Deutsche Telekom Software Codec on the Basis of the Texas Instruments
Parallel Processor TMS320C8x
- --------------------------------------------------------------------------------



To the extent that rights of third parties are involved, these must also be
taken into consideration accordingly, in this and all subsequent agreements.

The parties to the agreement particularly have the right to duplicate and revise
the software. One of the partners can also use individual program modules
without the approval of the other.

The software provided on diskettes must be identified with an appropriate
copyright note:

                                  (C) Copyright
                           TMS 320 C 80 software codec
                Deutsche Telekom AG                IAT AG
                        1995                       Version xx

In addition to a program version which can be run, both parties to the agreement
receive the source version in the programming language used in each instance
(e.g. "C"), with an indication of all the programming aids used, such as
compilers, linkers, tools, program libraries, etc., with product and
manufacturer designation, as well as the corresponding version numbers. The
source code must be completely documented.

Within the scope of the development work, the partners must observe the care
which is usual in the industry to protect the intellectual property rights of
third parties. This is particularly true for granting sublicenses.

If one of the partners fails to observe the care which is usual in the industry,
it is liable for all the disadvantages which the other partner incurs with
regard to the services to be performed by the former, due to the infringement of
intellectual property rights.

7.  Documentation of the Status of Development, Development Results

The progress of the development work must be constantly documented and kept
updated by the developing partner. Updated documentation must be handed over to
the other partner monthly. On the basis of this documentation, the current state
of development must be evident, and the work performed must be reproducible.
Documentation includes not only a description of the technology (hardware and
software including source codes), but also a listing of the funds and resources
used and the current schedule. The documentation must be drawn up with programs
under Windows. No special compensation is paid for provision of the required
documentation, it is included in the development costs. It must be ensured that
the other partner is constantly up to date on the progress of development, so
that any advance payments made by this partner are always offset by a
corresponding equivalent value of available development results.

- --------------------------------------------------------------------------------



8.   Demonstration of Time/Amount Framework

The proof that the time/amount assumptions of the developing partner on which
this agreement is based have actually been met is submitted by the developing
partner using the documentation to be drawn up according to Section 7, in time
manner before billing.

If the agreed time/amount assumptions are not met, only the services actually
performed can be billed.

If it is foreseeable that the time/amount assumptions will not be met (but no
later than when 90% of the contractually agreed rates have been reached), the
developing partner must inform the other partner immediately. The total costs of
the agreement are allowed to be at most 20% higher than the values stated in
Section 3 (Prices, Responsibility for Costs). An equalization within the work
sections to be performed by a party to the agreement is possible.

9.   Patents, Patentable Inventions

If patentable inventions come about within the scope of the work for achieving
the project goals stated in this agreement, these will be offered to the parties
to the agreement for joint filing. If there is no interest in joint filing of
patents, it is left to the discretion of the cooperation partner under whose
aegis the patentable invention came about whether or not it wishes to file an
application on its own.

10.  Confidentiality

The parties to the agreement undertake to use any documentation, drawings and
other information provided by the other partner only for fulfillment of the
obligations taken on, and to handle any business or industrial secrets of the
other partner of which they have gained knowledge as confidential. They will
limit dissemination of the information within their company to those employees
who must receive it on the basis of their activities. The receiving partner
undertakes to protect the confidentiality of the information received in the
same manner as it protects its own confidential information.

This obligation also applies to affiliates of the partners; however, they are
not considered third parties in the sense of this agreement. "Affiliated
companies" are understood to be:

- -    Any company in which the company of the party to the agreement or another
     affiliated company holds a majority interest, directly or indirectly, or on
     which it can exercise a controlling influence, directly or indirectly.

- -    Any company which holds a majority interest in the company of the party to
     the agreement, directly or indirectly, or which can exercise a controlling
     influence, directly or indirectly.

<PAGE>

General Cooperation Agreement concerning Joint Further Development of the
IAT/Deutsche Telekom Software Codec on the Basis of the Texas Instruments
Parallel Processor TMS320C8x
- --------------------------------------------------------------------------------



The information to be handled as confidential must be marked as "(name of owner)
- - Confidential." If any information which must be treated as confidential does
not have this marking, or if the confidentiality status was indicated orally,
this information must be designated as being confidential at the time it was
made known, and the recipient must receive written confirmation without delay.

The following information is not subject to the confidentiality obligation:

- -    information which the parties to the agreement already had in their
     possession at the time this agreement came into being,

- -    information which they have developed or will develop independent of
     information received from the other partner,

- -    information which is publicly available,

- -    information which the parties to the agreement have received or will
     receive, in accordance with the law, from third parties, without any
     obligation to keep it confidential,

- -    information released by the other party to the agreement.

Each partner is free to use the "retained knowledge" from the confidential
information of the other cooperation partner for any purpose, with the
restriction of not making it available to third parties during the agreed period
of time. Receiving confidential information does not establish any obligation to
restrict the location at which employees may work or the area of work, in any
manner. "Retained knowledge" is understood to mean information which was not
written down, which the employees who participated in the discussions remember.
This does not establish a license for patents and similar intellectual property
rights and copyrighted material.

The obligation to maintain confidentiality continues to apply even after
termination of the agreement, but no longer than five years after transfer of
the information in question.

11.  Approval and Warranty of Development Services

The partner with responsibility for the services (work sections) according to
Section 4 (Completion Dates) will make them available for approval tests to SfE
EKOM. This presentation is to be preceded by a function test by the developing
partner. Functional approval testing of the service is performed no later than
30 calendar days after the deadline for readiness for approval (readiness for
partial approval), in writing, by SfE EKOM or the Siegen office. In exceptional
cases where this is justified, the 30 calendar day limit can be extended to 40
calendar days by SfE EKOM.

<PAGE>


General Cooperation Agreement concerning Joint Further Development of the
IAT/Deutsche Telekom Software Codec on the Basis of the Texas Instruments
Parallel Processor TMS320C8x
- --------------------------------------------------------------------------------



Immediately before the approval test, the result achieved by the developing
partner will be presented and its functionality will be demonstrate
theoretically and practically (transfer). The partner not responsible for the
development shall have an opportunity to familiarize itself with the topics
inherent in the work section, and with the know-how in this regard.

If SfE EKOM or the Siegen office does not refuse approval within four weeks
after a work section has been presented as ready for approval, then approval is
considered to have been issued for all parts of the agreement. A reason for
refusing approval must be given within four weeks after approval was refused,
otherwise the refusal is considered rejected.

The warranty claims are directed at elimination of any defects, including
transport costs and incidental costs. They expire six months after approval.

If corrective work becomes necessary after expiration of the warranty period,
the developing partner is obligated to perform it in return for suitable
payment.

12.  Duration of the Agreement, Schedule

This general cooperation agreement begins on the date it is signed by the
partners, and is fixed until 6/30/96.

If the planned work is not completed by this date, the agreement is
automatically extended until completion of the development which has not been
finished, but no longer than until 12/31/96.

More details about the time distribution of the work sections are contained in
the enclosed project schedule.

Even after termination of the agreement, the utilization and exploitation rights
granted according to this cooperation agreement will apply, as will the
limitations of liability and the confidentiality obligation.

If the planned work is still not complete upon termination of the agreement on
12/31/96, the following will apply:

The utilization rights granted according to Section 5 refer, in this case, to
the work results which are available and have been paid for at the time the
agreement ends. Each party to the agreement can furthermore develop these
results itself, or have them developed by third parties on its behalf, until
they are ready for production, and is entitled to use internally, distribute,
change, particularly to edit, restructure, and further develop individual
jointly developed work results, without restriction. The work results up to the
time of termination of the agreement must be fully documented and given to the
other partner immediately, including the source code for which a patent has not
yet been filed at that time.

13.  Notice of Termination

13.1 General Information

Each party to the agreement has the right to terminate the agreement, in whole
or in part, without notice, if:

1.   the other party to the agreement does not pursue the development goals
     described in the agreement,
2.   the costs established in Section 3 are exceeded,
3.   the completion deadlines established in Section 4 are not met.

In case of notice of termination, in whole or in part, services will be billed
according to expenses actually incurred and documented, limited to a maximum of
the final offer sums in each instance.

Only those expenses which were proven to be necessary by the documentation which
accompanies development will be reimbursed. Expenses which were not reported
with documentation by the (leading) developing partner during the development
work will not be reimbursed.

The other rights to ordinary or extraordinary notice of termination remain
unaffected by this.

13.2 Special Provisions

In case of extraordinary notice of termination by a partner, the following
applies:

- -    The partner will inform the other partner, in writing, about started work
     that must still be completed; the partner is obligated to complete this
     work under the terms of the cancelled agreement.

- -    Any payments which must be made on the basis of the agreement, including
     remaining payments, are not allowed to exceed the total amount of the order
     which the partner would have received upon completion of the work if the
     agreement had not been cancelled.

- -    The developing partner must provide documentation for all items on which
     claims are based.

The partners are obligated to point these terms out to any third parties are
contractors, and are required to reach corresponding agreements if subcontracts
which are of importance for the agreement are involved.

The provisions concerning intellectual property rights and utilization rights
are not affected by notice of termination. They also apply for those
intellectual property rights for which applications were not filed until after
the notice of termination.

14.  Final Provisions

Changes in and additions to this agreement must be made in writing.

This agreement is subject to the laws of the Federal Republic of Germany. The
contract law related to the United Nations convention dated 4/11/80, concerning
agreements about international sale of goods (UNCITRAL) does not apply.

For any litigation resulting from or in connection with this agreement, the
courts in Bonn are agreed to have jurisdiction, if this is permissible by law.

If any provision of this agreement is invalid, or if this agreement contains
gaps, this does not affect the validity of the remaining provisions. Instead of
the invalid provision, it is agreed that the provision which comes closest to
the economic intent and purpose of the invalid provision will be agreed to. In
the case of gaps, the provision which corresponds to what would have been
agreed, according to the economic intent and purpose of this agreement, if the
matter had been agreed to right from the start, will be agreed to.

Re:                        Project Progress Report

Dear Sirs:

Delays in the critical phase of the project became obvious during the last
teleconference on 06/13/96. The primary reasons for these delays are related to
the development of the base board by IBM (ISDN and inlay). In turn, this causes
delays in the development of the ISDN drivers at IAT, since the latter must
build on the base board.

These delays affect subsequent driver development:

Table 1: Delayed Procedures in the Critical Phase

The aforesaid procedures were integrated into the updated, enclosed project plan
(see enclosure). Given that these tasks (see Table 1) fall into the project's
critical phase, the final completion date will be delayed. In order to prevent

                                      - 2 -

<PAGE>



further delays, we believe that it will be necessary for IBM's ISDN development
team to work even more closely with IAT than has been the case so far.

IBM is at present unable to forecast with certainty when the development of the
inlay will be completed. This is due to the absence of certain capabilities in
Videologic's technology. These capabilities are insufficient or not documented
at all. Only one developer at Videologic has any knowledge of these details.
However, since this person is also involved in other projects, he is not
available to IBM to a sufficient degree. IBM is therefore unable to state when
the development of the inlay will be completed.

We shall send a mutually agreed-upon letter to Videologic with the urgent
request that they support IBM in a more effective way than has been the case to
date. In the final analysis, the problems concerned are related to features
which, according to statements made by the representatives of Videologic's
management at the time, were supposed to exist. We depend on the support of
Videologic in the development of the inlay because, in our view, there is no
technical alternative.

However, we shall continue the development work on a parallel track in spite of
the absence of the second inlay. We hope that the problem will have been solved
by the time the MIKS integration phase (071) begins. Any further delays with
regard to the integration of the inlays will automatically delay the entire
project. This would mean that the aforementioned deadline (08/30/96) would have
to be postponed once again.

Finally, we would like to use this occasion to remind our partners that the
information concerning the amount of funds used since the onset of the
development work until now has still not been provided to us; in this connection
please see the "Cooperation Agreement Regarding the Development of MIKS, Version
3," Article 2 (responsibility for costs). Given that until now we have not
received any information in regards thereto, we must once again refer expressly
to said stipulation and request that you submit the respective data. We shall
process the data received and make them available to all project partners. We
have previously pointed out in each project progress report that this
information has not been provided to us. Should all cooperating partners no
longer wish to make said information available, we request that you declare as
much to us in a letter. In our view this would then necessitate amending the
agreement to reflect this change.

The Cooperation Agreement concluded by all parties will have to be extended in
light of the aforementioned delays. Under present stipulations, the agreement is
to terminate on 06/30/96.

We propose therefore that all cooperating partners provide a declaration to PZM
signed by the person who executed the agreement that they agree to an extension
of the agreement until 12/31/96.

Sincerely,
/signature/
Manfred Scheiter

                  Licensing and General Distribution Agreement

- --------------------------------------------------------------------------------


                                    Preamble

Telekom and IAT have developed and are developing products on the basis of
separate development agreements of the development associations (EG).

The existing contractual agreements of the EG are set forth in Appendix A.
Agreements not set forth therein, as well as supplementary agreements, are null
and void.

It is the purpose of the present agreement to launch and to exploit products
previously generated on the basis of the development agreements (Appendix B) or
products that are already contractually secured but are still in the process of
being developed (Appendix C) by way of, for example, direct distribution,
third-party sales, distribution, and licensing agreements on the basis of joint
use and exploitations rights.


Art. 1 Common Use and Exploitation Rights of the Parties

The purpose of this agreement is to facilitate the unrestricted economic use and
exploitation rights to the products -- which belong to both parties jointly --
that have already been generated on the basis of this development process or
that will be generated on that basis in the future. Accordingly, one party
cannot dispose of the product rights without the other party unless this
agreement contains express provisions to the contrary. If one party decides not
to continue participating in common efforts to exploit a product, the other
party shall be given the possibility to exploit the product on its own. The
licensing shares of the other party shall not be affected thereby.

As far as the previously concluded development agreements are concerned, the
parties depart from the premise that all rights are divided equally among them.


Art. 2 Distribution Rights and Licenses

The parties grant each other a worldwide distribution right subject to
remuneration.

These rights shall be based on specified and still to be specified agreements
concerning base systems, licensing shares, as well as delivery and procurement
terms and conditions, all of which shall be equal for both parties.

As a rule, the licensing share to be stipulated separately for each product
shall be distributed among the parties according to their respective development
expenditures.

The licensing share in the aforesaid agreements shall be established at ten
percent (10%) of the recommended list price, unless provided otherwise in the
individual agreements.

                  Licensing and General Distribution Agreement

- --------------------------------------------------------------------------------


The procedure for settling and offsetting licenses, as well as any and all rules
and modalities in connection therewith, shall be set forth in a separate
agreement.

- --------------------------------------------------------------------------------


Art. 3 Services and Costs to be Offset Separately

The following services and costs shall not be subject to the licensing agreement
and shall be stipulated at fixed prices by and between the parties. In the case
the parties cannot come to an agreement, cost prices according to VOL [German
contracting rules] shall apply.

o    deliveries of hardware

o    handbooks

o    software production (copying costs, diskettes)

o    packaging

o    shipping

o    modifications / adjustments

o    assembly

o    on-site installation

o    consulting and projection services

o    third-party software.

Art. 4 Product Parts not Subject to Licenses

Optional enhancements and conversions of the systems through third-party
hardware and software, which are not subject to the parties' mutual rights, are
not subject to this agreement.

Art. 5 Mutual Information and Agreement

The parties to this agreement undertake to inform each other with regard to all
important matters pertaining to the licensed products and to their mutual
cooperation.

This applies specifically to the following areas:

o    product design

o    product naming

o    marketing strategies.

Art. 6 Warranty

As a rule, the delivering party to this agreement shall release the receiving
party to this agreement from warranty claims related to the specified licensed
products.


Art. 7 Right to Grant Sub-Licenses

The parties may grant sub-licenses to third parties for the purposes of
third-party sales and distribution.

The granting or sale of rights or partial rights (e.g. production licenses) to
third parties shall be subject to the agreement of both parties.


Art. 8 Trade and Business Secrets

The parties to this agreement shall neither use nor make available to other
parties any and all trade and business secrets to which they have become privy,
by whatever means, in the course of implementing the present agreement, neither
during the lifetime of the agreement nor upon termination of same.

Sales information related to licensed products may be made available to third
parties only insofar as necessary for commercializing their distribution.


Art. 9 Assistance in Matters of Unfair Competition and Violations of Rights

The licensees shall notify each other of any and all violations of laws
governing unfair competition, as well as of violations of copyrights, marketing,
licensing, and other rights of which they gain knowledge. They shall assist each
other in defending themselves against such violations and shall agree on
appropriate measures to that end.


Art. 10 Service and Maintenance

The party to this agreement making the sale shall be responsible for servicing
and maintaining the sold products unless contractually stipulated otherwise.

The parties to this agreement undertake to make available all necessary measures
and information required for providing due service and maintenance of products
to customers.

- --------------------------------------------------------------------------------


Art. 11 Continuous Development

The continued development of the products shall occur in the framework of the
existing and future development associations (EG). It shall be budgeted subject
to mutual agreement and in consideration of the experience gained on the market
and shall be implemented in the context of development agreements, to the extent
that both parties declare these to be necessary.

Both parties to this agreement have the right not to participate in the
continued development of one or several products. In such cases the other party
must be notified thereof in writing. The outcome of the continuing development
of the products concerned shall subsequently be set forth in supplementary
agreements. In such cases, the party willing to continue its development efforts
shall be granted the right to do so on its own on the basis of the existing
developments.

To this end, the party not interested in continuing the development efforts
shall make available, free of charge, all results developed in mutual
cooperation.


Art. 12 Termination of the Agreement

This agreement is concluded for an unspecified duration.

The right to terminate the agreement for important reasons remains unaffected
thereby.

A termination automatically voids all agreements deriving from this agreement
between the parties effective on the same termination date.

Subsequently, the specified licensing duties shall remain in effect until the
cumulative licensing revenue has reached the level of the investments made for
development purposes.

Agreements concluded by one party to this agreement relative to third parties in
the course of this agreement that must be maintained for satisfying obligations
shall not be affected by a termination.

All rights to the products shall revert to the parties to this agreement in
their entirety once this agreement has been terminated.


Art. 14 Disputes

All disputes arising from the interpretation and implementation of this
agreement shall be subject to the laws of the Federal Republic of Germany. The
place of jurisdiction is Bonn.

                  Licensing and General Distribution Agreement

- --------------------------------------------------------------------------------


The parties shall bring disputes before an official court of arbitration before
taking recourse to ordinary courts of law.


Art. 15 Cure Clause

If this agreement lacks a specific provision, or if a provision of this
agreement is null and void, is questionable, or cannot be implemented, the
effectiveness of the remainder of this agreement shall not be affected thereby.

The parties shall adopt that legal provision in place of the possibly missing,
void, questionable, or non- implementable provision by a provision most suitable
to bring about the success envisioned by the parties to this agreement.

     Program and all copyright, patent rights and other intellectual property
     rights relating solely thereto are vested in the originator.

3.3 IAT and TI shall maintain as confidential any source code of the other
party's Products and derivative software based on the other party's Products and
shall not disclose or otherwise make available such source code without entering
into a source code license with at as leas as stringent terms as TI's current
standard source code license agreement in effect at the time of disclosure; a
copy of which is attached hereto as Appendix B and incorporated herein by this
reference. TI shall notify IAT in the event that TI makes changes to such
standard source code license agreement.

3.4 IAT and TI shall ensure that all end users are restricted by written
agreement from copying, distributing, translating, adapting, arranging or
otherwise altering any object code versions of the TI and IAT Products, or
reverse compiling such object code except as allowed by local legislation

necessary to achieve interoperability of an independently created program with
other programs. Such end users shall be specifically prohibited from copying,
adapting or reverse compiling such object code for the purpose of error
correction.

3.5 IAT may sublicense original and derivative versions of the TI products in
source code form to third parties provided that IAT enters into a source code
sublicense agreement with terms no less stringent than TI's Standard Source Code
License agreement applicable to the products licensed by TI hereunder. This
applies to all third parties except for those that are involved with the
manufacture, sale or licensing of semiconductor products or development of
software which operates on digital signal processors other than those
manufactured by TI, in which case TI has the right to withhold approval of such
license issuance by IAT

3.6 Subject to the provisions of Section 4 herein, with the exception of the
ISDN library software, IAT grants to TI a worldwide transferable,
non-assignable, non-exclusive fully paid up license to use, modify, compile or
otherwise develop as applicable software programs which may be original or

4.   CONSIDERATION

4.1 Notwithstanding the provisions of 4.3, 4.4, 4. and except as provided in
Section 4.2, TI and IAT understand and agree that the cross licenses granted
herein represent full and fair consideration one for the other, and that no
license fees or royalty payments shall be payable by either party to the other
in respect thereof.

4.2 With respect to the T.123 DataBeam license, IAT understands that TI will
negotiate this license on behalf of IAT and will extend a most favored nations
license back to IAT as a result of the final license agreement negotiated.

4.3 In the event that TI licenses third parties the use of H.320 libraries as
ported by IAT hereunder for purposes other than evaluation, TI shall remit to
IAT the greater amount of a)50% of the license fee collected by TI for such
library or b)$20,000 US. However, no such obligation will be required of TI when
supplying customers who have existing licenses of the IAT Products prior to the
execution of this agreement.

4.4 In the event that TI licenses third parties the use of the reference design
as productized by IAT hereunder for purposes other than evaluation, TI shall
remit to IAT the greater amount of a) 35% of the license fee collected by TI for
such library or b)$7,000 US.

4.5 In the event that TI sells an evaluators kit defined as the bundled hardware
and software as ported and productized by IAT hereunder and separately charges
such third party a fee for use of such kit, TI shall remit to IAT 10% of the kit
fee collected by TI for such kit. IAT recognizes that for its own business
reasons, TI may choose to sell such kit without fee or without separately
identifying fees and agrees that in such event no fees are due IAT.

4.6 In consideration of the above, IAT agrees that no fees will be due on
revenues received by TI as a result of the licensing arrangements in 4.3, 4.4
and 4.5 until IAT has completed and TI approves the productization activities
specified in the statement of work, after which all accrued amounts will be paid
in full.

Furthermore IAT agrees to provide dedicated engineering support services to TI
in a timely manner to support its licensees. TI agrees to provide timely
engineering support services to IAT on an as needed basis.

3.11 During the term of this Agreement and for a period of eighteen (18) months
     thereafter, TI or its authorized representatives, upon advance written
     notice, shall have access to such portion of LICENSEE's records as is
     necessary to allow TI to determine whether LICENSEE is substantially in
     compliance with this Agreement. In no event shall audits be made hereunder
     more frequently than every six (6) months. Such access shall be (a) during
     LICENSEE's regular business hours, (b) arranged so that, to the extent
     possible, LICENSEE's regular business activities are minimally disrupted
     and (c) under the terms of an appropriate confidentiality agreement
     executed by the individual(s) conducting such audit. If TI determines,
     after conducting such audit, that LICENSEE is not substantially in
     compliance with its obligations to protect TI's proprietary rights,
     LICENSEE shall pay the costs of such audit, which in no case shall exceed
     Fifteen Thousand U.S. Dollars (U.S. $ 15,000). Otherwise, TI shall pay the
     costs of such audit. Such payment will not preclude TI from exercising any
     right which it may have under this Agreement. LICENSEE shall immediately
     correct any deficiencies discovered during the course of the audit. Any
     audit conducted by TI authorized personnel shall provide LICENSEE with at
     least two (2) days advance notice of any audit requested by TI and shall be
     held during normal business hours. Furthermore, any audit that may be
     requested by TI shall be conducted in such a manner so as not to adversely
     impact normal business operations.

                               still video images

- --------------------------------------------------------------------------------


1     Objectives and duties

1.1   The objective of the project is to develop a black box model for
      compression of the image data of still pictures. The software package to
      be created, in the programming language C, with defined inputs and
      outputs, shall allow compression and decompression of image data from the
      field of medicine -- with some loss, yet still with excellent quality.

1.2   Goal:

      The decompressed image shall be of excellent quality. In other words, at a
      compression rate of 1:20 the PSNR should be approximately 30. During the
      course of transmission of the compressed data, the decompressed image is
      to be assembled in such a way that a complete but rudimentary image can be
      seen at first and then the quality of the picture improves as time goes
      on. The final configuration of the image should be adjustable to three
      quality levels.

1.3   The Customer plans to port this code into the environment of the C80
      processor from Texas Instruments, and therewith to achieve rapid and
      high-quality transmission of image data over a narrow ISDN band (64 kb/s).
      The code which is to be created shall be designed for this purpose. In
      addition, the Contractor shall support the Customer in the porting of the
      code.

          Wavelet Data Compression for the transmission of high-quality
                               still video images


- --------------------------------------------------------------------------------

2.    Concept

The following three-stage procedure is an obvious choice for the data image
compression:

1.    Transformation of the image data, by means of a wavelet filter, into a
      low-pass image containing only scales greater than a specified length, and
      into residual portions of the picture which contain the smaller scales.

2.    In the second step, these different portions of the scale -- corresponding
      to the bands in the case of a Fourier transformation -- are quantified
      individually.

3.    In the third stage the data are coded, making use primarily of the
      statistics for the color and gray values which occur in the individual
      scales.

      This outline is to be optimized for the supplied medical images, and three
      compression plans of differing quality are to be defined. The quality of
      the images shall be defined through the following criteria:

1.    PSNR value in dB.

2.    HVS value (subjective evaluation first by members of the Contractor's 
      staff and then by experts designated by IAT).

- --------------------------------------------------------------------------------

1.    Purpose of this Agreement

This agreement concerns the cooperation between ODE and IAT with regard to the
distribution of products offered by IAT on the basis of its resale price list of
March 6, 1996, and the products offered by ODE in the field of microscopics. The
distribution activities may be extended, subject to further agreement, to
endoscopic products. Both parties to the present agreement are interested in
closely cooperating with each other and in establishing a long-term partnership.


2.    Resale

ODE shall have the right to procure products from IAT in accordance with the
latter's "resale" price list and to resell the products at its discretion to its
customers. To support the distribution activities of ODE, IAT shall make
available, to the extent possible, demonstration equipment, as well as data
sheets, catalogues, and the like.


3.    Terms and Conditions

ODE shall procure IAT's products in accordance with the latter's resale price
list. In turn, IAT may procure OLYMPUS microscopes, including any and all
accessories, at a resale discount of 20%. Should a customer request that only
one company issue both the order and the invoice for a given project, both
parties to this agreement shall be willing and able to comply. In such cases,
the party not participating in the sale shall assist the party making the offer
with information and materials. The "internal" settlement of accounts between
the parties to this agreement shall be effected after the respective customer
has been billed. This agreement shall apply exclusively to Germany.

The Memorandum of Understanding executed in September 1995 shall remain in
effect.


4.    Service

Olympus shall be responsible for servicing the microscopes. IAT shall be
responsible for servicing IAT products.

5.    Training

Olympus shall provide all initial training for the microscope program, free of
charge, excluding travel and hotel costs, subject to agreement with IAT. The
initial training regarding IAT products shall also be provided free of charge,
excluding travel and hotel costs, subject to agreement with OLYMPUS.

under this Banking relationship against

Primary Obligor - Name(s) and Address(es):

I.A.T. Deutschland GmbH
Interactive Media Systems
Fahrenheitstra e 9
28359 Bremen

- --    if there are several primary obligors, also against each one of them
      individually --

I/we hereby assume the Directly Enforceable Guarantee up to a maximum amount of

                                  125,000.00 DM

in words: one hundred twenty five thousand Deutsche Mark.

In addition, the following provisions shall apply to this guarantee; I/we am/are
jointly referred to as "guarantor" therein:


1.    Scope of the Guarantee

The guarantor shall be liable under this guarantee only up to the maximum amount
set forth above, even in cases if the guarantor assumes the guarantee for
several primary obligors.


2.    Continuation of the Guarantee

The guarantee shall remain in effect beyond any termination of the Banking
relationship until any and all claims of the Bank secured by this guarantee have
been satisfied in their entirety; in


                                      - 1 -

<PAGE>


                     Directly Enforceable Minimum Guarantee

- --------------------------------------------------------------------------------


particular, the guarantee shall not expire if the primary obligor temporarily
repays the claims secured hereunder.


3.    Enforcing the Guarantee, Objection (Refusal of Performance)

(1)   If the claims of the Bank that are secured by this guarantee are due and
      payable, and if the primary obligor does not satisfy these claims, the
      Bank may enforce the guarantee against the guarantor who, under the
      guarantor of a directly enforceable guarantee, shall undertake to pay the
      Bank upon demand. The Bank does not have the obligation to first seek
      recourse before the courts against the primary obligor or to sell the
      collateral provided to it.

(2)   The guarantor's obligation to pay shall also apply if the primary obligor
      has the right to challenge the transaction underlying the debt (waiver of
      the guarantor's right to challenge the principal debt pursuant to ss. 770
      para 1 BGB [Burgerliches Gesetzbuch - German Civil Code]). Furthermore,
      the guarantor shall not have the right to assert that the Bank could
      satisfy its claims by offsetting them against a claim of the primary
      obligor that is due (waiver of the guarantor's right to demand the
      offsetting of claims pursuant to ss. 770 para 2 BGB).


4.    Transfer of Collateral

(1)   Until the debt secured by this guarantee has been discharged in full, the
      guarantor shall not have the right to demand transfer of collateral
      created for the Bank for the purpose of securing the guaranteed claims.

(2)   To the extent that collateral is transferred to the guarantor by law (e.g.
      rights of lien), the statutory provisions shall apply. If the Bank's
      claims exceed the maximum amount set forth above, and if the collateral
      being transferred to the guarantor by law also serve to secure the
      unsecured portion of the Bank's claims, the Bank's right to satisfy its
      claims shall have priority relative to the guarantor.

(3)   If the guarantor has fully discharged the debt secured hereunder, and if
      the Bank must release the collateral pursuant to the collateral
      agreements, the Bank shall transfer the collateral created for it by the
      primary obligor -- if necessary, on a pro-rated basis -- to the guarantor;
      the Bank shall transfer collateral created by third parties to the
      respective guarantor unless stipulated otherwise with that guarantor.

<PAGE>


                     Directly Enforceable Minimum Guarantee

- --------------------------------------------------------------------------------


(4)   Any and all claims of the guarantor against other guarantors for
      settlement and transfer of the collateral shall not be affected by the
      foregoing provisions.


5.    Application of Payments Received

To the extent that payment provisions do not stipulate otherwise, the Bank may
apply any and all proceeds from the sale of the collateral created for the Bank
by the primary obligor or by a third party first to those claims that are
secured by the collateral but are not subject to this guarantee and/or to that
portion of its claims that exceeds the maximum amount secured hereunder. This
shall also apply to guarantees created by the guarantor for the purpose of
additionally securing the claims against the primary obligor, unless these were
designed to support the guarantee. Likewise, the Bank may apply any and all
payments made by the primary obligor or on account of the latter in accordance
with its priority ranking to its claims that are not secured, in whole or in
part, under this guarantee.


6.    Liability of Several Guarantors

(1)   If several guarantors are securing the same debt of the primary obligor
      pursuant to separate guarantee agreements, each individual guarantor shall
      be liable -- vis-a-vis the Bank to the exclusion of any joint and several
      liability -- for the entire guarantee assumed by the respective guarantor
      until all claims of the Bank secured by the respective guarantor have been
      satisfied, irrespective of any and all payments made hereunder by another
      guarantor.

(2)   If several guarantors assume the guarantee under this guarantee agreement,
      they shall be jointly and severally liable to the Bank. This means that
      the Bank may claim the maximum amount set forth above from each individual
      guarantor, in whole or in part; however, overall, the Bank's claims may
      not exceed said maximum amount.

(3)   Compensatory claims of the guarantor called to liability hereunder against
      the other guarantors shall not be affected by the foregoing provision.


7.    Additional Guarantees

The guarantee shall apply in addition to any and all other guarantees provided
by the guarantor.

                     Directly Enforceable Minimum Guarantee

- --------------------------------------------------------------------------------



8.    Deferment and Release of Collateral

The guarantor shall not be released of its liability under this guarantee if the
Bank grants a deferment to the primary obligor, releases other guarantors from
their liability, or releases other collateral, in particular, if the Bank
permits dispositions of items subject to the Bank's right of lien and if this
occurs in connection with the due execution and settlement of the Bank's
relationship with the primary obligor or for the purposes of safeguarding
justified interests of the primary obligor or the Bank. The guarantor shall also
not be released from its liability if the Bank relinquishes collateral in order
to satisfy an obligation to release collateral pursuant to other collateral
agreements.


9.    Right of the Guarantor to Terminate the Guarantee

(1)   The guarantor may terminate the guarantee in writing -- unless the
      guarantee is limited in duration -- at the end of one year from the time
      at which it provided the guarantee. The termination shall be effective
      subject to a period of three months upon receipt of same by the Bank. The
      right to termination for important reasons shall not be affected thereby.

(2)   The guarantor's liability shall remain in full force and effect once the
      termination becomes effective; however, it shall be limited to the secured
      claims existing at the time the termination became effective. The
      provisions of this guarantee shall remain in effect until the secured
      debts of the primary obligor have been repaid in full. Unless stipulated
      otherwise under repayment provisions, any and all payments, of whatever
      kind and nature, that are received on account of the primary obligor after
      the termination has become effective shall be credited first to the Bank's
      unsecured claims and/or to that portion of the Bank's claims that are not
      secured hereunder at the time the guarantee is terminated. Any and all
      additional payments shall reduce the secured debt.

(3)   Until the termination becomes effective, the primary obligor may avail
      itself of loans promised before the termination was received.

(4)   Once the termination is in full force and effect, the guarantor shall also
      be liable for those claims of the Bank against the primary obligor arising
      from the fact that the Bank has entered into an obligation, in the name of
      the primary obligor, vis-a-vis third parties -- e.g. by providing a
      guarantee or by guaranteeing payment -- to assume the liability for debts
      incurred by the primary obligor.

- --------------------------------------------------------------------------------


10.   Release of the Collateral

(1)   Upon satisfaction of the Bank's claims that are secured hereunder, the
      Bank shall release the guarantee.

(2)   Upon request, the Bank shall undertake to release the guarantee, as well
      as other collateral provided to it (e.g. assigned receivables, mortgages),
      in whole or in part, at its discretion, to the respective guarantor before
      the Bank's claims secured under this guarantee have been satisfied in full
      if the realizable value of all collateral exceeds

                                      100 %

      of the Bank's secured claims at all times. If no percentage was entered
      above, and if no other agreements were made, a rate of 100% shall apply.

(3)   The realizable value of the guarantee shall be determined on the basis of
      the guarantor's current asset and income situation at the time the release
      is requested.


11.   Notifications Regarding the Status of the Principal Debt

If need be, the guarantor shall obtain information as to the status of the
principal debt from the primary obligor.


12.   Choice of Law

The laws of the Federal Republic of Germany shall apply to the guarantee
relationship hereunder.

General Credit Terms


1     Credit Line, Overdrafts

In availing itself of the credit line, the Borrower may not exceed the credit
limit. Nevertheless, should the Borrower overdraw the credit line, that amount
exceeding the credit limit shall be repaid to the Bank immediately. Overdrafts
of this type shall entail higher interest charges. Overdrafts do not increase
the originally granted credit line, even if the Bank has tolerated temporary
overdrafts.


2     Joint and Several Liability

In the case of more than one Borrower, all Borrowers shall be liable, jointly
and severally.


3     Disclosure of Financial Condition

Pursuant to the provisions of the banking law, the Borrower shall undertake to
regularly disclose to the Bank, as long as the credit line is in effect, its
asset and income situation, to allow the Bank to inspect its books and records,
and to provide any and all information required in connection therewith. To this
end, the Bank may obtain the requisite records directly from the persons and/or
entities consulting the Borrower in bookkeeping and accounting matters. If the
Borrower prepares annual financial statements, it shall submit a copy of same,
if necessary in audited form, to the Bank without being requested to do so. The
Bank is entitled to obtain information concerning the Borrower from governmental
authorities, registries of deeds, other public offices, and insurance companies;
to obtain records from said entities; and to inspect records and deeds in the
offices of said entities. This includes, in particular, notarized copies of
entries in public registries, governmental certifications, and records
pertaining to insurance policies. The Bank may submit the Loan Agreement for
such purposes.


4     Insurance Policies

The Borrower shall undertake to properly insure the collateral, including any
and all accessories, against any and all risks which, in the Bank's view, must
be insured, and to prove such insurance to the Bank upon request at any time, in
particular, by submitting the requisite insurance policies. The Borrower shall
be responsible for satisfying these conditions even if the collateral belongs to
others.



                                      - 5 -

<PAGE>




5     Collateral

If the financial position of the Borrower, an equally liable person or entity,
or a guarantor deteriorates or is at significant risk, or if significant changes
occur in the value of the collateral to be created in accordance with the Loan
Agreement, which increase the risk of due repayment of the loan relative to the
financial condition at the time the loan was granted to an extent that is not
insignificant, the Bank may require the Borrower to create additional, suitable
collateral at the Bank's discretion, even if until such time the Bank did not
require such collateral. The same shall apply if statements about the financial
situation of the Borrower, an equally liable person or entity, or a guarantor
turn out in hindsight to have been incorrect.

The Borrower may avail itself of the loan only if any and all conditions have
been met, the required collateral has been created, and the Bank has verified
that everything is in due order.


6     Refinancing

The Bank shall have the right to assign its claims under the Loan Agreement in
the event of a refinancing and to convey the collateral created by the Borrower
to the refinancing entity.


7     Termination

The Bank may terminate loans and promised loans, in regards to which the parties
did not stipulate either a temporal limit or different provisions concerning the
period of notice, at any time without complying with a period of notice. If the
Bank exercises this right of termination, it shall take the Borrower's
legitimate interests into account.

If the loan is terminated without a period of notice, the Bank shall grant to
the Borrower a reasonable time frame for settling the loan.

The Bank shall be available at any time to discuss possibilities of achieving
mutual agreement in these matters.


8     Costs

Any and all expenses and ancillary costs incurred in connection with this
agreement, including the costs of commissioning the responsible cooperative
trust agency, shall be borne by the Borrower. The expenses and ancillary costs
shall be debited to the Borrower's current bank account.

9     Modification of the Agreement

Any and all modifications of and amendments to this agreement or an agreement
concerning the termination thereof shall be made in writing to be effective.


10    Partial Invalidity

Guarantee for Claims Under the Banking Relationship

Guarantor (Name, Address, Date of Birth)               Bank

IAT AG                                                 Volksbank Sottrum eG
Aarestra e 17                                          GroBe StraBe 22
CH - 5300 Vogelsang                                    27367 Sottrum


The guarantor assumes the following guarantee relative to the Bank:


      1 For the purposes of securing any and all existing, future, and qualified
claims of the Bank or a successor or assignee of the Bank that continues the
banking relationship

against

Primary Obligor(1)

IAT Deutschland GmbH, Fahrenheitstra e 1, 28359 Bremen,

or its universal successor and assignee, and, if the primary obligor is a
company or corporation, against its successor and assignee,

under the banking relationship, in particular,

o     under current accounts or under loans of any type whatsoever, bills,
      checks, deliveries, and services;
o     under guarantees, as well as any and all other undertakings on account of
      third parties; as well as
o     under receivables acquired from third parties in connection with customary
      banking business, bills, and checks, even if the collateral is created in
      connection with a particular loan,

I/We assume

a directly enforceable guarantee up to

      350,000.00 DM

for current account number 10.4690.001.



                                      - 8 -

<PAGE>



2     The guarantee is given for an unlimited time period.


3 The guarantee may be terminated in writing one year after it has been given,
at the earliest, subject to a period of notice of three months. The right of
termination for important reasons shall remain unaffected thereby.

When the termination takes effect, the guarantee shall be limited to the
existing claims secured hereunder at the time. However, the guarantor shall not
be liable for any and all loan promises made by the Bank after receipt of the
notice of termination. The stipulations of this guarantee shall remain in force
until the claims against the primary obligor that are secured hereunder have
been satisfied in full.


4 All payments of the guarantor shall serve as collateral until the Bank's
claims have been fully satisfied; the Bank's claims against the primary obligor
shall be transferred to the guarantor to the extent of the latter's performance
only after any and all claims of the Bank have been satisfied in full. The same
shall apply to any and all accessory rights. Unless stipulated otherwise in an
agreement between the guarantor and the Bank, the Bank shall undertake to
transfer the nonaccessory rights to the guarantor. At the request of the
guarantor, the Bank shall transfer these claims to the guarantor at an early
date, provided it no longer needs them, not even temporarily.


5 The Bank shall have the right to apply any and all proceeds from the
collateral, payments of the primary obligor or other persons and/or entities
liable hereunder, as well as any and all other payments received first to its
claims that exceed the amount secured hereunder and/or, in the case of a
termination pursuant to item 3 above, to the then remaining secured balance.


6 If this agreement is executed by several guarantors, all of them shall be
jointly and severally liable (joint guarantee).


7 If the Bank's claims against the primary obligor are secured, at present or in
the future, by additional guarantees that are separate from the present
agreement, each guarantor shall be liable hereunder, irrespective of the other
guarantees, for the entire amount stipulated in the respective guarantee
(secondary joint guarantee) -- in deviation from ss. 759 BGB2 [Burgerliches
Gesetzbuch - German Civil Code]. The guarantee under the present document shall
have the same rank as any and all other guarantees assumed by the guarantor.


8 The guarantee waives the right to challenge and to offset pursuant to ss. 770
BGB2, as well as the defense of failure to purse remedies pursuant to ss. 771
BGB2; the guarantor also waives its rights pursuant to ss. 776 BGB2 (release of
collateral and of guarantors). The Bank shall therefore have the right to grant
additional loans to the primary obligor; to enter into an agreement with the


                                      - 9 -

<PAGE>



primary obligor concerning the deferment of its claims against the latter; and
to arrive at a settlement, in or out of court, regarding its secured claims
against the primary obligor, without having to obtain the guarantor's consent.


9 Any and all modifications of and amendments to this guarantee agreement, as
well as any agreement concerning its termination, shall be made in writing to be
effective.


10 This guarantee agreement shall remain in full force and effect, even if
individual provisions thereof have not become integral part of the agreement,
are ineffective, or have not been implemented. The content of this agreement
shall be subject to applicable law to the extent that individual provisions have
not become integral part of this agreement or are ineffective.


11 The General Terms and Conditions of the Bank (AGB) shall also apply. The AGB
may be inspected at the Bank's branches; a copy thereof shall be made available
upon request.

Text of applicable laws:

Art. 769 BGB:           If several persons/entities secure one and the same
                        debt, all of them shall be jointly and severally liable
                        therefor, even if they do not jointly assume the
                        guarantee.

Art. 770 BGB:           The guarantor may refuse to satisfy the creditor as long
                        as the primary obligor has the right to challenge the
                        legal transaction underlying his debt. The guarantor has
                        the same right as long as the creditor can satisfy any
                        and all claims due against the primary obligor by
                        offsetting them.

Art. 771 BGB:           The guarantor may refuse to satisfy the creditor's
                        claims as long as the creditor has not successfully
                        enforced its claims against the primary obligor (defense
                        of failure to pursue remedies).

Art. 776 BGB:           If the guarantor waives a preferential right in
                        connection with the claim, a mortgage or a maritime
                        mortgage pertaining to the claim, a right of lien
                        pertaining to the claim, or the right against a
                        coguarantor, the guarantor shall be released from his
                        obligation insofar as he could have obtained damages
                        under the right waived pursuant to ss.774 BGB. This also
                        applies if the waived right came into existence after
                        the guarantee was assumed.

      designed to secure the claims against individual obligors, such fact shall
      be negotiated separately and expressed through suitable additional
      wording, such as "and against each one of the obligors."

      or

            with the guarantee

                                    Agreement



between                             Grissemann Consulting SA, Chatillens
                                    (hereafter KG)


and                                 IAT AG, Turgi
                                    (hereafter IAT)


Preamble
- --------

Presumably until December 3, 1992 IAT will have a financial reorganization and
wants to reorganize the responsibilities of its administration. Since on the one
hand the outcome of the financial reorganization is open and on the other hand
the necessary work time for this position varies strongly but lies under 50%,
the occupation of this position under a regular working contract is unsuitable.

1.    Scope of work and resposibilities

      With effect from September 1, 1992 KG takes on the responsibility for the
      administration and accounting of IAT. In doing so, he can rely on the
      assistance of IAT staff.

      His work place is Turgi, Montreux and Chatillens as required.

2.    Employment of time

      The employment of time is defined by the requirements of IAT and is agreed
      upon with the management. It will amount to a minimum of 30 percent and is
      not upwards limited until the conclusion of the financial reorganization
      KG ensures that he can always be reached by telephone.

3.    Remuneration

      The remuneration corresponds to a pro rata salary including social
      security of an IAT manager and will amount to SFr. 5'000.--/month from
      September 1, 1992.

      Grissemann Consulting SA will bill the company on a monthly bases. The
      invoice will be settled at the end of each month together with the salary
      payments of IAT.

      IAT will not be charged with any social security expenses.

      Domestic travel expenses are included in the remuneration.

                                             


<PAGE>



4.    Notice of termination

      Until the conclusion of the financial reorganization the agreement cannot
      be terminated. After that the agreement can be terminated by either side
      at 30 days' written notice at the end of a quarter.

5.    Final clause

      Under the condition of a positive outcome of the financial reorganization
      IAT and KG reserve the right to redefine the work time percentage and
      remuneration of this agreement at the beginning of 1993.


Turgi and Chatillens, September 1, 1992

                 Addendum to the Agreement of September 1, 1992



between                               Grissemann Consulting SA, Chatillens
                                      (hereafter KG)


and                                   IAT AG, Turgi
                                      (hereafter IAT)



1.    From January 1, 1995 the fee will amount to SFr. 775.--/day. The yearly
      adaptation shall correspond to the salary increases of IAT managers with a
      similar position.

2.    KG will have at his disposal a company automobile corresponding in its
      class and equipment to the company car of other IAT managers.


All other clauses of the agreement remain unchanged.

- --------------------------------------------------------------------------------

5.    If Mr. Gudauski is prevented through no fault of his own (e.g. due to

      entitled.

      Regardless of the foregoing, the employment relationship shall terminate
      at the end of the month in which the employee has reached the legal
