kind to which the Holder is or will be a party and by which the Holder will be bound at the time of such performance. The representations and warranties of the Holder set forth in this paragraph shall not survive the completion of the Arrangement and will expire and be terminated on the earlier of the Effective Time and the date on which this letter agreement is terminated in accordance with its terms.

Notwithstanding any provision of this letter agreement to the contrary, (a) but subject to the terms and conditions of the Arrangement Agreement, I, in my capacity as director or officer of the Acquiror, shall not be limited or restricted in any way whatsoever in the exercise of my fiduciary duties as director or officer of the Acquiror, and (b) I will be entitled to exercise my rights under the Holder RSUs, the Holder PSUs, the Holder DSUs and the Holder Options to acquire Newmont Shares (which Newmont Shares, will be subject to the terms of this letter agreement).
