No failure on the part of any party hereto to exercise, and no delay in exercising any right, power or remedy created under this Agreement, will operate as a waiver thereof, nor will any single or partial exercise of any right, power or remedy by any such party preclude any other or further exercise thereof or the exercise of any other right, power or remedy.

If any term or part of this Agreement is held to be illegal, invalid or unenforceable by a court of competent jurisdiction, it is the intention of the parties that the remaining terms or partial terms will constitute their agreement with respect to the subject matter of this Agreement and all remaining terms or partial terms will remain in full force and effect. To the extent legally permissible, any illegal, invalid or unenforceable provision of this Agreement will be replaced by a valid provision that will implement the commercial purpose of the illegal, invalid or unenforceable provision. 4.6 Integration.
