2.1      Party B's existing six operating subsidiaries, namely Guangdong Mobile,
         Zhejiang Mobile, Jiangsu Mobile, Fujian Mobile, Hainan Mobile and Henan
         Mobile in its current operating regions, and the seven operating
         subsidiaries, namely Beijing Mobile, Tianjin Mobile, Shanghai Mobile,

         provinces, municipalities and autonomous region, and shall comply with
         Party A's centralized business management measures.

  ARTICLE THREE   PRINCIPLES FOR REVENUE SHARING OF INTER-PROVINCIAL SALES OF
              ADDED VALUE FOR THE "SHENZHOUXING" VALUE-ADDING CARDS

                                       2
<PAGE>   4
         A "Shenzhouxing" subscriber, i.e., the holder of the Pre-paid Card, may
purchase a Value-adding Card in another operating region and add value, in which
case the operating subsidiary in such subscriber's home operating region (i.e.,
the operating region where such subscriber's Pre-paid Card is registered) shall
settle accounts with the operating subsidiary in the operating region where such
Value-adding Card is registered. Eighty-five percent of the added value of such
Value-adding Card shall be settled for the account of the operating subsidiary
in the home operating region of such "Shenzhouxing" subscriber, and the
remaining 15% shall be settled for the account of the operating subsidiary in
the operating region where such Value-adding Card is registered.

       ARTICLE FOUR   SETTLEMENT PRINCIPLES FOR DOMESTIC INTER-PROVINCIAL
                 ROAMING OF THE "SHENZHOUXING" PRE-PAID SERVICES

         Party A and Party B shall conduct roaming settlement in accordance with
the existing "Shenzhouxing" Pre-paid Services usage charge standards, as may be
adjusted from time to time.

4.1      Settlement of base roaming charge in connection with domestic
         inter-provincial roaming services:

         In respect of roaming into another operating region by the
         "Shenzhouxing" subscribers of both Parties, the operating subsidiary in
         the home operating region of such subscribers shall pay, through
         settlement with Party A, 80% of the base roaming charge (currently
         being RMB 0.80 per minute) to the operating subsidiary in the visited
         operating region.

4.2      Settlement of long distance charge when roaming:

         In respect of roaming into another operating region by the
         "Shenzhouxing" subscribers of both Parties, the operating subsidiary in
         the home operating region of such subscribers shall pay, through
         settlement with Party A, to the operating subsidiary in the visited
         operating region all long distance charges incurred when such
         subscribers make calls while roaming. The operating subsidiary in the
         home operating region of such subscribers may keep all long distance
         charges incurred when such subscribers receive calls while roaming.

4.3      Currently, international roaming services are not available to the
         "Shenzhouxing" subscribers. If international roaming services are made
         available to the "Shenzhouxing" Pre-paid Card in the future, Party A
         and Party B will enter into a supplemental agreement providing for the
         settlement of the relevant international long distance charges and base
         international roaming charges in accordance with the settlement
         principles set forth in the Inter-Provincial Network Interconnection,
         Domestic and International Roaming and Settlement Agreement, dated May
         5, 2000, between Party A and Party B.

         The Parties hereby acknowledge and agree that, in consideration of the
domestic inter-provincial roaming clearing services provided by Party A to Party
B, Party B shall pay Party A a domestic inter-provincial roaming call record
processing fee of RMB 0.02 for each call record processed. If international
roaming services are made available to the "Shenzhouxing" Pre-paid Card in the
future, Party A shall provide international (including Hong Kong, Macao and
Taiwan) roaming clearing services to Party B, for which Party B shall pay Party
A international roaming clearing fees in accordance with the supplemental
agreement referred to in Article 4.3 above.

         settle the domestic inter-provincial long distance roaming charges in
         connection with the "Shenzhouxing" pre-paid service on a monthly basis.
         The cycle of such settlement shall be from 0:00 on the 21st day of the
         proceeding month to 24:00 on the 20th day of the current month. Such
         settlement shall be made on the strength of the settlement statement

         reference and verification purpose. If Party B has any different
         opinions on such settlement statement furnished by Party A, the
         settlement shall be nevertheless made on the basis of Party A's such
         settlement statement for the time being. The portion of settlement in
         dispute shall be confirmed by the Parties and adjusted accordingly in
         the succeeding month.

6.3      Party A and Party B hereby acknowledge and agree that the Parties shall
         settle the roaming settlement and clearing fees in connection with the
         "Shenzhouxing" pre-paid service on a monthly basis. The cycle of such
         settlement shall be the same as the settlement of the roaming charges.
         The roaming settlement and clearing fees shall be listed as a separate
         item in the domestic inter-provincial roaming charge settlement
         statement.

6.4      Party A shall furnish the settlement statement of the proceeding month
         to Party B's Mainland China operating subsidiaries by the 18th day of
