Subject to compliance with applicable Law, Bidders shall have the right to approve (such approval not to be unreasonably withheld) any references to them contained in such filing or correspondence.

(i) Not to own, lease, manage, operate, control, advise, engage in, or own stock or otherwise own an equity or economic interest in, any Person engaged in providing telecommunication services which are competitive with the services provided by Maxcom as of the date hereof (“Competitive Activities”) in Mexico; provided that, notwithstanding the foregoing, nothing in this Section 2.5(c)(i) will restrict or prevent in any manner Nexus Partners from maintaining a purely passive investment in any Person who is engaged in any Competitive Activities so long as the aggregate interest
