of any other warranties, express or implied. THE COMPANY DISCLAIMS AND EXCLUDES
ALL OTHER EXPRESS WARRANTIES, AND DISCLAIMS AND EXCLUDES ALL WARRANTIES
IMPLIED BY LAW, INCLUDING WITHOUT LIMITATION THOSE OF MERCHANTABILITY AND
FITNESS FOR A PARTICULAR PURPOSE. To the extent that applicable law prohibits the
exclusion of implied warranties, the duration of any applicable implied warranty is limited to
the period specified for the express warranty above. Some states do not allow limitations on

or written description of the Product is for the sole purpose of identifying it and shall not be
construed as an express warranty.
Whenever possible, each provision of this Limited Warranty shall be interpreted in such
manner as to be effective and valid under applicable law, but if any provision is held to be
