duration or geographical scope thereof, or otherwise, then the parties agree
that such court shall modify such restriction, only to the extent necessary to
render it enforceable and, in its reduced form, such restriction shall then be
enforced, and in its reduced form this paragraph shall be enforceable in the
manner contemplated hereby.

declared illegal or unenforceable by a court of competent jurisdiction and
cannot be modified to be enforceable, excluding the general release language,
such provision shall immediately become null and void, leaving the remainder of
this Agreement in full force and effect. Moreover, if any such provision
determined to be invalid, illegal or unenforceable can be made valid, legal or
enforceable by modification thereof, then the party for whose benefit the
provision exists, may make such modification as necessary to make the provision
valid, legal and enforceable.

          11.  Nonadmission of Wrongdoing. Employee agrees that neither this
Agreement nor the furnishing of the consideration for this Agreement shall be
deemed or construed at anytime for any purpose as an admission by Employer of
any liability or unlawful conduct of any kind.

          26.  Amendment. This Agreement may not be modified, altered or changed
except upon express written consent of both parties wherein specific reference
is made to this Agreement.

          27.  Entire Agreement. This Agreement sets forth the entire agreement

understandings between the parties except the Non-Disclosure Agreement. Employee

ADVISED TO CONSULT WITH AN ATTORNEY PRIOR TO EXECUTION OF THIS AGREEMENT AND
GENERAL RELEASE.
