WHEREAS, the proposed sale of the CH Membership Interests owned by CCLP and Beatty and the tego capital stock owned by CG to Boingo pursuant to the Securities Purchase Agreement would constitute a less than 100% change in ownership (as such term is defined in the Agreement) and requires the consent of the Commissioner pursuant to Section 10.3(B)(ii) of the Agreement; and
