 9.6. Counterparts. This Agreement may be executed in several counterparts, including counterparts transmitted by telecopier, telefax, or any
similar means of electronic transmission, each of which shall be an original, and all of which together shall constitute but one and the same instrument. 
  
 9.7. No Third Party Beneficiaries. This Agreement confers no rights whatsoever upon any persons, other than the Parties hereto. 
  
 9.8. Waiver. No failure on the part of any Party to exercise, and no
delay in exercising, any right hereunder shall operate as waiver thereof, nor shall any single or partial exercise of any right hereunder by any Party preclude any other or further exercise of any other right and no waiver shall be valid unless in a

to the courts for resolution. The use of any ADR procedures will not be construed under the doctrines of laches, waiver or estoppel to affect adversely the rights of either party. Nothing in this Section 9.9.2 will prevent either Party from
resorting to judicial proceedings (subject to Section 9.10 below) if (i) good faith efforts to resolve the dispute under these procedures have been unsuccessful or (ii) interim relief from a court is necessary to prevent serious and irreparable
injury to one party or to others.

Fees. If any action at law or in equity (including mediation or ADR) is necessary to enforce or interpret the terms of this Agreement the prevailing Party shall be entitled to reasonable attorneys’ fees, costs and disbursements in addition
to any other relief to which such Party may be entitled.
