Because Fund I, Fund II and Co-Invest have divested themselves of voting and investment power over the reported securities they hold and may not revoke that delegation on less than 61 days notice, Fund I, Fund II and Co-Invest disclaim beneficial ownership of the securities they hold for purposes of Section 13(d) of the Act and therefore disclaim any obligation to report ownership of the reported securities under Section 13(d) of the Act.
