“The Distributor shall not offer any Shares and shall not approve any creation or redemption order hereunder if and so long as the effectiveness of the Registration Statement then in effect or any necessary amendments thereto shall be suspended under any of the provisions of the 1933 Act or if and so long as a current Prospectus as required by Section 10 of the 1933 Act is not on file with the SEC.”
