19. This Agreement shall be governed by and construed in accordance

with the laws of Utah, excluding any choice of law provisions that would

otherwise require application of laws of any other jurisdiction. In the

event it becomes necessary for either Party to enforce its rights under this

Agreement, then with or without litigation, the prevailing Party shall be

entitled to recover all reasonable expenses, including attorney fees and

costs, arising out of the enforcement of its rights.

20. The failure of a Party to require the performance of a term or

obligation under this Agreement, or the waiver by a Party of any breach,

shall not prevent subsequent enforcement of such term or obligation or be

deemed a waiver of any subsequent breach under this Agreement. No waiver of

any provision of this Agreement shall be valid unless in writing and signed

by the Party against whom charged.

this Agreement shall be construed as if it did not contain such provision.

Each provision shall be deemed enforceable to the fullest extent available

under applicable law.
