the AMBE™ Software to be free from defects in materials and 
workmanship under normal use for a period of ninety (90) days 
from the date of delivery.   DVSI further warrants that the  VC-

operate in accordance with the written specifications delivered to 
END USER with the Voice Codec. 
 
7.2 

Except as stated in Section 7.1, the  VC-20™ ATC-10b 

Vocoder Board and  AMBE™ Software are provided "as is" 
without warranty of any kind.  DVSI does not warrant, guarantee 
or make any representations regarding the use, or the results of 
the use, of the Voice Codec or AMBE™ Software with respect to 
its correctness, accuracy, reliability, currentness or otherwise.  
The entire risk as to the results and performance of the VC-20™ 
A T C-10b Vocoder Board or AMBE™ Software is assumed by the

7.4 

Except as specifically set forth in this Section 7.0, DVSI 

makes no express or implied warranties including, without 
limitation, the warranties of merchantability or fitness for a 
particular purpose or arising from a course of dealing, usage or 
trade practice, with respect to the Voice Codec or AMBE™ 
Software.  Some states do not allow the exclusion of implied 
warranties, so the above exclusion may not apply to END USER.  
No oral or written information or advice given by DVSI or its 
employees shall create a warranty or in any way increase the 
scope of this warranty, and END USER may not rely on any such 
information or advice.  The limited warranties under this section 
7.0 give END USER specific legal rights, and END USER may 
have other rights which vary from state to state.

for loss of business profits, business interruption, and loss of 
business information), even if DVSI or any DVSI representative 
has been advised of the possibility of such damages.  
 
8.2 

Because some states do not allow the exclusion or 

limitation of liability for consequential or incidental damages, the 
above limitations may not apply to END USER.
