(a) hubco shall be entitled by notice in writing to the Relevant Participant(s) to withdraw the Stage 1 Submission or the Stage 2 Submission or to decline to submit a Stage 2 Submission (as the case may be) and to be paid the Incurred Project Development Fee with the relevant date for calculation being the date the change was notified to hubco; and
(b) unless the period of ten (10) years after the Commencement Date has expired, to the extent the New Project in question is a Qualifying Project, the Relevant Participant(s) shall not be entitled to procure the Required Facilities and/or the provision of the Project Services outside the terms of this Agreement without recommencing this New Project Approval Process and, if they do so, such action shall and shall be deemed to be in breach of Clause 9 (Exclusive Nature of this Agreement).
6.2 The Relevant Participant(s) may, at any time, give notice in writing to hubco that they propose to cancel a New Project (a Cancellation Notice) without completing the process set out in paragraphs 3 to 5, in which case the Relevant Participant(s) shall pay hubco the Incurred Project Development Fee in respect of the cancelled New Project with the relevant date for calculation being the date of the Cancellation Notice. In such circumstances, unless the period of ten (10) years after the Commencement Date has expired then, to the extent the New Project in question is a Qualifying Project, the Relevant Participant(s) shall not be entitled to procure the Required Facilities and/or the provision of the Project Services outside the terms of this Agreement without recommencing this New Project Approval Process and, if they do so, such action shall and shall be deemed to be in breach of Clause 9 (Exclusive Nature of this Agreement).
