(c) As promptly as practicable following termination of this Agreement by either party in accordance with Section 1, Cantor shall return the Provided Assets to BGC. BGCP shall further be permitted to withdraw a portion of the Provided Assets from time to time only if mutually agreed by BGCP and CFLP that funds in excess of amounts reasonably required by CFLP have been deposited.

(d) To the extent required, CFLP and BGC shall cause their subsidiaries to amend their pre-existing clearing agreement to implement the terms and conditions of this agreement, and to obtain regulatory approval for such amendments as may be required.
