Without limiting the foregoing, the Custodian further reserves the right, in its sole discretion, to decline to accept custody of, and to provide services with respect to, any Digital Asset.

Subject to and in accordance with directions from or on behalf of the New Company, the Custodian shall disseminate to the National Securities Clearing Corporation, on each day that the New York Stock Exchange is open, such information with respect to the issuance or redemption of Company shares in “Creation Unit” aggregations that the Custodian receives from or on behalf of the New Company.
