** of each party. If any provision of this Agreement is determined to be invalid, illegal
** or otherwise unenforceable, such provision will be enforced to the extent possible consistent
** with the intent of the parties, and the remaining provisions of this Agreement will remain in
** full force and effect. This Agreement will be fairly interpreted in accordance with its terms
