As soon as practicably possible following receipt of the payment set out in Clause 2.1 of this Amendment, Pledgee shall notify the Company of the release of the Released Shares in the form of Schedule 1 (Release from Pledge) to this Amendment although any failure to deliver such notification will not affect the effectiveness of the release of the Released Shares as contemplated herein.
