Severability

If any provision of these Terms is found to be invalid, illegal, or unenforceable by a court or other tribunal of competent jurisdiction, such provision shall be enforced to the maximum extent permissible so as to effect the intent of the parties, and the remaining provisions of these Terms shall continue in full force and effect.

In the event that a provision is deemed invalid or unenforceable in part rather than in its entirety, the valid portion shall remain in effect. The parties agree to replace any invalid or unenforceable provision with a valid and enforceable provision that, to the greatest extent possible, achieves the same economic, legal, and commercial objectives as the original provision.

Waiver: No failure or delay by either party in exercising any right, power, or privilege under these Terms shall operate as a waiver thereof, nor shall any single or partial exercise preclude any other or further exercise of any such right. Any waiver must be in writing and signed by the waiving party.
