                  AMENDMENT TO INTELLECTUAL PROPERTY AGREEMENT

                  This Amendment, dated as of March 31, 2003 is made by and

                  WHEREAS, effective as of August 20, 2002, the Parties entered
into an Intellectual Property Agreement (the "Intellectual Property Agreement"),
pursuant to which the Parties have allocated to TWE and the TWE Broadband Group
the intellectual property assets related to the TWE Broadband Business and have
allocated to Holdco and the TWE Non-Broadband Group the intellectual property
assets related to the TWE Non-Broadband Business; and

                  WHEREAS, the Parties now wish to amend the Intellectual
Property Agreement to revise the schedule of TWE Non-Broadband Group Patents and
the schedule of Excluded TWE Broadband Group Trademarks; and

                  NOW THEREFORE, in consideration of the mutual promises and
covenants herein contained and for other good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the Parties agree as
follows:

                  1.       Definitions. Terms used and not defined herein shall
have the meanings assigned to them in the Intellectual Property Agreement.

                  2.       Schedule B to the Intellectual Property Agreement

                  5.       This Amendment may be executed in any number of
counterparts, each of which shall be deemed an original, but all of which
together shall constitute one instrument. Except to the extent specifically
amended and supplemented hereby, all of the items, conditions and provisions of
the Intellectual Property Agreement shall remain unmodified, and the
Intellectual Property Agreement, as amended and supplemented by this Amendment,
is confirmed as being in full force and effect.
