implied, express or statutory, including, without limitation, the
implied warranties of merchantability, noninfringement of third party
rights and fitness for a particular purpose. The TWAIN Working Group
disclaims all liability for damages, whether direct, indirect,
special, incidental, or consequential, arising from the reproduction,
distribution, modification, or other use of the TWAIN Toolkit.

As a condition of this license, Customer agrees to include in software
programs based in whole or in part on the TWAIN Toolkit the following
providions in (i) the header or similar file in such software and (ii)
prominently in its documentation and to require its sublicensees to
include these provisions in similar locations: The TWAIN Toolkit is
distributed as is. The developer and distributors of the TWAIN Toolkit
expressly disclaim all implied, express or statutory warranties
including, without limitation, the implied warranties of
merchantability, noninfringement of third party rights and fitness for
a particular purpose. Neither the developers nor the distributors will
