Section 1, for execution on any operating system. Copies of

to Licensee and Licensee's exclusive remedy shall be, at RibbonSoft's
option, either (A) return of the price Licensee paid for the Licensed
Software, or (B) repair or replacement of the Licensed Software,
provided Licensee returns to RibbonSoft all copies of the Licensed
Software as originally delivered to Licensee. RibbonSoft shall not
under any circumstances be liable to Licensee based on failure of the
Licensed Software if the failure resulted from accident, abuse or
misapplication, nor shall RibbonSoft under any circumstances be liable

return to RibbonSoft all copies of Licensed Software that were supplied
