The Authority will consider in good faith each High Value Change Proposal put forward by Sub-hubco and the Authority will not unreasonably withhold or delay its consent to a High Value Change Proposal. If, acting reasonably, the Authority finds that any material aspects of the High Value Change Proposal are unsatisfactory to it, it shall notify Sub-hubco of the same and offer reasonable assistance to Sub-hubco to enable it to revise and resubmit the High Value Change Proposal as soon as reasonably practicable.
