     WHEREAS, in accordance with Paragraph 25 of the TPC-5 Cable Network

Parties


                                       1



to the TPC-5 Cable Network C&MA, commensurate with the requirements of the
Additional Parties and other Parties to the TPC-5 Cable Network C&MA, and

     WHEREAS, in accordance with Subparagraph 13(a) of the TPC-5 Cable Network
C&MA, certain existing Parties desire to reassign their MIU Path Assignments or
to expand their assigned capacity in the TPC-5 Cable Network and thereby make
commensurate changes in their Investment Shares, Voting Interests, Ownership

TPC-5 Cable Network, and to reflect such changes in replacement Schedules B, C,
D, E, F, and G of the TPC-5 Cable Network C&MA, and

     WHEREAS, certain existing Parties in the TPC-5 Cable Network C&MA have
undergone organizational changes, resulting in new addresses or new

E, F and G attached hereto, and

     WHEREAS, AT&T as owner of Segment A of the TPC-5 Cable Network, the new

and

     NOW, THEREFORE, the Parties hereto agree with each other as follows:


                                       2

interests, the ownership interests, the allocation of capital, operating and
maintenance costs and the assignment of MIUs of the TPC-5 Cable Network are
revised in accordance with Schedules A, B, C, D, E, F and G hereto. As of the

     2. Each of the Additional Parties hereby:

        (a) agrees to accept and abide by the terms and conditions of the
TPC-5 Cable Network C&MA, which is incorporated by reference and made a part
hereof;

        (b) agrees to assume responsibility to pay its proportionate share
of any costs incurred under the TPC-5 Cable Network C&MA prior to becoming a
Party thereto; and

        (c) agrees to accept and abide by all decisions already taken in
relation to the TPC-5 Cable Network by the Parties to the TPC-5 Cable Network
C&MA prior to its becoming a Party thereto.

     3. Unless otherwise required by the context, VNPT and TI shall be
collectively referred to as "Vietnamese Party" or "VP" in the TPC-5 Cable
Network C&MA, under which VNPT and TI shall assume, jointly but not on a
several basis in shares as agreed between VNPT and TI, all interests, rights,
obligations and liabilities allocable to VP under TPC-5 Cable Network C&MA.
All interests, rights, obligations and liabilities of VP under the TPC-5

                                       3



date of TI's notification to other Parties in writing of such title transfer.
Upon such transfer, notwithstanding Paragraph 20, all rights and obligations of
TI independently under the TPC-5 Cable Network C&MA shall cease, and any
reference to VP in the agreements in association with the TPC-5 Cable Network
C&MA shall be deemed to be a reference to VNPT. Notwithstanding the foregoing,
such notification by TI shall not relieve TI from any liabilities, costs,
damages or obligations incurred prior to such notification being made.

     4. AT&T and KDD shall bill the Additional Parties and the existing Parties
acquiring capacity for their proportional shares, as specified in Schedule E of
this Amendatory Agreement No. 1, of the costs of the TPC-5 Cable Network

Committee.

     5. Upon execution of this Amendatory Agreement No. 1, the Additional
Parties are hereby admitted as signatories to the TPC-5 Cable Network C&MA and
deemed to be Parties thereto.


                                       4

made in accordance with Subparagraph 13(b) of the TPC-5 C&MA.

     8. Paragraph 2, Subparagraphs 3(a), 7(b), and 15(a), are hereby amended and
