Securityholders Agreement

17. Securityholders Agreement

        IPC and certain members of our management that acquired securities of Parent in 2007, at that time, entered into a securityholders agreement that governs certain relationships among, and contain certain rights and obligations of, such shareholders. The securityholders agreement, among other things:

• •

  limits the ability of the shareholders to transfer their securities in Parent, except in certain permitted transfers as defined therein;

  •

  provides for certain co-sale rights; and

  •

  provides for certain rights of first refusal with respect to transfers by shareholders other than to certain permitted transferees.
