Any time after the fourth (4th) anniversary of the date of this Agreement, Investor may request one registration (the “Demand Registration”) under the Securities Act of 1933, as amended (the “Securities Act”), of its Registrable Securities (as defined below). The Demand Registration shall be on such form as the Company shall select. The Demand Registration shall specify the number of Registrable Securities to be registered. The Company shall use best efforts to cause a registration statement to be filed within 180 days after the date on which the initial request by Investor is received by the Company and shall use its best efforts to cause such registration statement to be declared effective by the U.S. Securities and Exchange Commission (“SEC”) as soon as practicable thereafter. The Company shall use best efforts to keep such Demand Registration current and effective until the Registrable Securities registered thereby cease to be Registrable Securities.
