TO THE EXTENT PERMITTED BY LAW, THE REMEDIES
PROVIDED HEREIN ARE THE SOLE AND EXCLUSIVE
REMEDIES. IN NO EVENT SHALL MILLER BE LIABLE
FOR DIRECT, INDIRECT, SPECIAL, INCIDENTAL OR
CONSEQUENTIAL DAMAGES (INCLUDING LOSS OF

ANY OTHER LEGAL THEORY.

ANY EXPRESS WARRANTY NOT PROVIDED HEREIN

AND DISCLAIMED BY MILLER.

Some states in the U.S.A. do not allow limitations of how long
an implied warranty lasts, or the exclusion of incidental,
indirect, special or consequential damages, so the above
limitation or exclusion may not apply to you. This warranty
provides specific legal rights, and other rights may be
available, but may vary from state to state.

In Canada, legislation in some provinces provides for certain
additional warranties or remedies other than as stated
herein, and to the extent that they may not be waived, the
limitations and exclusions set out above may not apply. This
Limited Warranty provides specific legal rights, and other
rights may be available, but may vary from province to
province.
