6.2

shall not use, disclose, make, or have made any copies of the 
Proprietary Information, in whole or in part, without the prior 
written consent of DVSI.

 

 
6.3 

END USER shall make reasonable efforts to notify and 

inform its employees having access to the Proprietary Information of 
END USER's limitations, duties and obligations regarding nondisclosure 
and copying of the  IMBE™ Software.  Proprietary Information shall 
be used only by employees of END USER and only at the Designated 
Site, except as provided under this agreement. 
 
6.4 

END USER shall have no obligations for disclosure or use of 

Proprietary Information which: (i) is already known to END USER, at 
time of disclosure by DVSI; (ii) is or becomes publicly known through 
publication, inspection of product or otherwise through no wrongful 
act of END USER; (iii) is received from a third party without 
restriction and without breach of this Agreement; (iv) is independently

6.5 

Notwithstanding any terminat ion pursuant to Section 3.0, 

the obligations set forth in this Section 6.0 shall survive termination 
of this Agreement. 
 

7.0 

Limited Warranty

 

 
7.1 

DVSI warrants the Voice Codec and the  IMBE™ 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 Voice Codec and the  IMBE™ Software 
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 Voice Codec and  

IMBE™ 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 
IMBE™ Software with respect to its correctness, accuracy, reliability, 
currentness or otherwise.  The entire risk as to the results and 
performance of the Voice Codec or  IMBE™ Software is assumed by 
the END USER.  After expiration of the warranty period, END USER, 
and not  DVSI or its employees, assumes the entire cost of any 
servicing, repair or correction of the Voice Codec or the  IMBE™  
Software. 
 
7.3 

DVSI warrants that it has the right to enter into this 

Agreement and to grant a license to use the IMBE™ Software to END 
USER. 
 
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  IMBE™ 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. 
 
 

8.0 

Limitation of Liability 

 
8.1 

In no event shall DVSI be liable for any special, incidental, 

indirect or consequential damages resulting from the use or 
performance of the Voice Codec or  VC-20  IMBE™ Vocoder 
Board  whether based on an action in contract, tort (including 
negligence) or otherwise (including, without limitation, damages 
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.  
 
8.3 

DVSI's maximum liability for damages arising under this 

Agreement shall be limited to 20% (twenty percent) of the fees 
paid by END USER for the particular Voice Codec or  VC-20 
IMBE™ Vocoder Board  which caused the damages or that is the 
subject matter of, or is directly related to, the cause of action. 
 

9.0 

Taxes

 

 
9.1 

All payments required under Section 4.0 or otherwise 

under this Agreement are exclusive of taxes and END USER agrees 
to bear and be responsible for the payment of all such taxes 
(except for taxes based upon DVSI's income) including, but not 
limited to, all sales, use, rental receipt, personal property or other 
taxes which may be levied or assessed in connection with this 
Agreement.

 

 
 

10.0 

Export

 

 
10.1 

United States export laws and regulations prohibit the 

exportation of certain products or technical data received from 
DVSI under this Agreement to certain countries except under a 
special validated license.  As of May 20, 1996 the restricted 
countries are: Libya, Cuba, North Korea, Iraq, Serbia, Montenegro, 
and Iran.  The END USER hereby gives its assurance to DVSI that 
it will not knowingly, unless prior authorization is obtained from 
the appropriate U.S. export authority,  export or re-export, 
directly or indirectly to any of the restricted countries any 
products or technical data received from DVSI under this 
Agreement in violation of said United States Export Laws and 
Regulations.  DVSI neither represents that a license is not required 
nor that, if required, it will be issued by the U.S. Department of 
Commerce.  Licensee shall assume complete and sole 
responsibility for obtaining any licenses required for export 
purposes.
