                                                                  EXHIBIT 10.2 

                              LICENSE AGREEMENT 

This Agreement ("Agreement") is entered into by and between the Semiconductor 
Group of TEXAS INSTRUMENTS INCORPORATED, a Delaware Corporation with its 
offices at 8505 Forest Lane, M/S 8670, Dallas, Texas 76243 ("TI" herein), and 
IAT AG with principal offices at IAT AG, Geschaftshaus Wasserschloss, 
Aarestrasse 17, CH5300 Votgelsang-Turgi, Switzerland ("LICENSEE" herein). 

1. PURPOSE AND SCOPE 

   For the purpose of assisting LICENSEE in its development of products for 
use with TI's TMS320C8X product family, TI agrees to deliver to LICENSEE the 
software product(s) and related documentation described as Licensed Products 
in Schedule 1 (collectively referred to as "Licensed Product"). LICENSEE 
wishes to combine the Licensed Product with a video telephony platform that 
will run with one or more of TI's 320C8x product family. The aforementioned 
platform will be used and will be licensed to OEMs and/or sold to end user 
customers. LICENSEE agrees that such Licensed Product shall be used solely in 
conjunction with systems designed exclusively for one of TI's 320C8x product 
family, and that such use shall be subject to the terms and conditions of 
this Agreement. 

2. TITLE 

   TI represents that it has the rights to grant the license to the Licensed 
Product. Nothing contained in this Agreement shall be construed as 
transferring any right, title, or interest in the Licensed Product to 
LICENSEE except as expressly set forth herein. 

3. LICENSE AND OBLIGATIONS 

   3.1 TI grants to LICENSEE, only under TI's copyrights and trade secrets, a 
non-transferable, non-assignable, non-exclusive license solely to use, 
modify, compile, or otherwise develop as applicable, a software program 
("Modified Application Program"), which may be original or derivative with 
respect to the Licensed Product, for use solely in conjunction with systems 
designed exclusively for TI's 320C8X product family. 

   3.1.1 LICENSEE may make one copy of the Licensed Product for internal 
back-up purposes. LICENSEE agrees that as a condition for obtaining its 
rights hereunder, each copy of the Licensed Product, or any portion thereof 
or documentation therefor, shall contain a valid copyright notice and any 
other proprietary notices, including the copyright notices of TI and/or TI's 
suppliers, which appear on or in the Licensed Product and documentation 
delivered to LICENSEE hereunder or as TI may require from time to time, in 
order to protect TI's copyright and other ownership interests. Presence of a 
copyright notice does not constitute an acknowledgment of publication. 
LICENSEE shall reproduce on the copy of the Licensed Product, and on all 
copies of the Modified Application Program, all copyright notices and any 
other proprietary notices exactly as and where they appear on the Licensed 
Product delivered, or as closely as possible where a change in media 
precludes exact reproduction. 

   3.1.2 LICENSEE shall maintain any source code of the Licensed Product as 
confidential, and shall not disclose, distribute, or disseminate any such 
source code to any third parties. 

   3.2 LICENSEE is expressly prohibited from reverse compiling, reverse 
assembling, and reverse engineering any portion of the Licensed Product 
provided in object format. 



                                                   TI/IAT

   3.3 TI grants to LICENSEE under only TI's copyrights and trade secrets, a 
non-transferable, non-assignable, non-exclusive license solely to copy and 
distribute only object code versions of the Modified Application Program for 
use solely in conjunction with systems designed exclusively for TI's 320C8X 
product family. 

   3.3.1 LICENSEE shall ensure that all sublicensees must reproduce on every 
copy made, all copyright notices and any other proprietary notices exactly as 
and where they appear on the Licensed Product delivered, or as closely as 
possible where a media change precludes reproduction. 

   3.3.2 LICENSEE shall ensure that all sublicensees are expressly prohibited 
from reverse compiling, reverse assembling, and reverse engineering the 
Licensed Product or the Modified Application Program. 

   3.3.3 LICENSEE shall ensure that all sublicensees restrict their end users 
by written agreement from copying, modifying, distributing, reverse 
engineering and reverse assembling or reverse compiling the Licensed Product 
or the Modified Application Program, except that end users may make one (1) 
copy for back-up purposes only. 

   3.4 LICENSEE shall ensure that all of its end users are restricted by 
written notice from copying, modifying, distributing, reverse engineering and 
reverse assembling or reverse compiling the Licensed Product or the Modified 
Application Program. 

   3.6 LICENSEE agrees that it will not disclose any portion, or all of the 
Licensed Product or the accompanying documentation in any form to any 
employees, with the exception of employees (i) who require access thereto for 
a purpose authorized by this Agreement and (ii) who have signed an 
appropriate employee agreement committing them to abide by the obligations 
and restrictions in this Agreement or who are otherwise required to maintain 
confidentiality of information hereunder pursuant to an enforceable written 
agreement that requires such employee to use the same degree of care, but no 
less than a reasonable degree of care, as the LICENSEE uses to protect its 
own similiar confidential information, and to prevent any use not authorized 
herein, dissemination to any employee of LICENSEE without a need to know, 
communication to any third party or publication of the confidential 
information. 

   3.7 LICENSEE shall ensure that the same degree of care is used to prevent 
the unauthorized use, dissemination, or publication of the Licensed Product 
as Licensee uses to protect its own confidential information, but in no event 
shall the safeguards for protecting such Licensed Product be less than a 
reasonably prudent business would exercise. Such safeguards, shall include at 
a minimum, storage of Licensed Product in a secure, locked area when not in 
use, LICENSEE shall prevent unauthorized use or disclosure of Licensed 
product by its employees, including those who have access to the Licensed 
Product. 

   3.7.1 LICENSEE's employees who have access to the Licensed Product shall 
be instructed to copy Licensed Product only as permitted under this Agreement 
and to disclose Licensed Product only to other employees of LICENSEE that 
LICENSEE has authorized to have access to the Licensed Product.

   3.8 LICENSEE recognizes and acknowledges all TI's claim(s) to techniques, 
algorithms, and processes contained in the Licensed Product which have been 
developed, acquired, or licensed by TI, or any modification or extraction 
thereof, constitute trade secrets of TI and/or its suppliers, and will be 
used by LICENSEE only in accordance with the terms of this Agreement. 
LICENSEE will take all measures reasonably required to protect the 
proprietary rights of TI and its suppliers in the Licensed Product and will 
promptly notify TI of any lost or missing items and take all reasonable steps 
to recover such items. 

   3.9 If LICENSEE engages in a Clone Product development or marketing of a 
LICENSEE created product having capabilities that are similar to those 
provided by the Licensed Product or TI's 320C8X product family ("Clone 
Product" herein), during the term of this Agreement, LICENSEE shall ensure 
that there is no sharing with the Clone Product development of (i) the 
Licensed Product or (ii) any laboratory, office or research facilities 
containing Licensed Product. LICENSEE shall not use any TI trademarks in 
association with any Clone Product. The provisions of this Paragraph 3.10 
shall survive the termination, cancellation or expiration of this Agreement 
for a period of twelve (12) months after the Licensed Product is returned to 
TI or destroyed. 

   3.10 LICENSEE shall maintain reasonable documentation sufficient to 
identify all employees, Contractors, all employees of such Contractors, or

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 this 
agreement, LICENSEE shall pay the costs of such audit. 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. 

   3.12 The obligations of this section 3 shall survive termination or 
expiration of this Agreement.
