facility),  several of the  lenders of the  Broadband  credit  facility or their
respective  affiliates  have in the past  performed,  and may in the future from
time to time perform,  investment banking,  financial  advisory,  lending and/or
commercial  banking  services for the Registrant and certain of its subsidiaries
and affiliates, for which service they have in the past received, and may in the
future receive, customary compensation and reimbursement of expenses.
