13.1. Failure or unreasonable delay by any Party to perform or otherwise act in accordance with any non-monetary, material provision of this Agreement for a period of thirty (30) days after written notice from the non-breaching Party (“Cure Period”), constitutes a default under this Agreement. The notice shall specify the nature of the alleged default.

13.2.

15.3. Notwithstanding any provision to the contrary, in the event GWRI or the Customer elects to sell one or more of the private regulated utilities indicated in Exhibit E, and the acquirer makes such a transaction contingent upon the termination of the Agreement for that utility only, the Customer and FATHOM agree to renegotiate an increase in FATHOM fees contained within this contract. The negotiation shall be in good faith and shall be only with respect to the reapportion of the necessary ongoing revenues and costs contemplated under this Agreement to reflect the sale of the private regulated utility.
