                                OTHER AGREEMENTS


         2.1 Perfection of Transfers by Peck Holdings. Notwithstanding anything
to the contrary contained in the Stock Purchase Agreement, Purchaser hereby
acknowledges and agrees that, subject to the satisfaction of the applicable
closing conditions set forth in Article VII of the Stock Purchase Agreement, it
shall not delay the Subsequent Closing that includes the transfer of the
Colombian Acquired Companies, the Nicaraguan Acquired Companies, the Peruvian
Acquired Companies, the Uruguayan Acquired Companies and the Venezuelan Acquired
Companies as a result of (a) any delay in the perfection of the transfers (the
"Liquidating Distributions") by Peck Holdings of the Equity Interests in the
Acquired Companies of which it is the registered owner to Latin America Cellular
Holdings B.V. ("LACHBV") or (b) the failure of Peck Holdings to distribute
assets and liabilities with respect to Dutch taxes for the period (the "Dutch
Residency Period") in 2004 in which Peck Holdings was a resident of the
Netherlands. BellSouth represents that LACHBV is the owner of the Equity
Interests transferred pursuant to the Liquidating Distributions. To BellSouth's
knowledge, the steps required to perfect title to such Equity Interests after
such Subsequent Closing are set out on Exhibit A, and BellSouth agrees to assist
Purchaser with such steps as reasonably requested by Purchaser, including the
execution of the proxy attached hereto as Exhibit B on the Subsequent Closing
Date. Purchaser

agrees that, after such Subsequent Closing, (i) BellSouth shall continue to
control the dissolution of Peck Holdings, including the preparation and filing
of Peck Holdings' Dutch income tax returns for the Dutch Residency Period,
(ii) Phil Wallace (or another designee of BellSouth) shall remain the liquidator
of Peck Holdings in connection with such dissolution, (iii) the completion of
such dissolution may be deferred for a reasonable period until the Liquidating
Distributions are perfected, and (iv) Peck Holdings and LACHBV shall enter an
Assignment and Assumption Agreement in the form attached hereto as Exhibit C
pursuant to which LACHBV agrees to pay the Dutch corporate income tax liability
of Peck Holdings for the Dutch Residency Period. BellSouth agrees that it shall
promptly indemnify LACHBV for the excess of such corporate income taxes paid on
behalf of Peck Holdings over the amount of a Dutch capital tax refund due to
Peck Holdings that was assigned to LACHBV pursuant to a certain Assignment and
Assumption Agreement dated October 27, 2004.



                                   ARTICLE III

                                  MISCELLANEOUS

         3.1 Ratification and Confirmation of the Stock Purchase Agreement; No
Other Changes. Except as modified by this Amendment No. 4, the Stock Purchase
Agreement is hereby ratified and confirmed in all respects. Nothing herein shall
be held to alter, vary or otherwise affect the terms, conditions and provisions
of the Stock Purchase Agreement, other than as contemplated herein.

         3.2 Severability. If any provision of this Amendment No. 4 shall be
held invalid, illegal or unenforceable, the validity, legality or enforceability
of the other provisions hereof shall not be affected thereby, and there shall be
deemed substituted for the provision at issue a valid, legal and enforceable
provision as similar as possible to the provision at issue.

         3.3 Applicable Law.  This Amendment No. 4 shall be governed by and
construed and enforced in accordance with the internal laws of the State of New
York without giving effect to the principles of conflicts of law thereof.

         3.4 Counterparts. This Amendment No. 4 may be executed and delivered
(including by facsimile transmission) in one or more counterparts, all of which
shall be considered one and the same agreement and shall become effective when
one or more counterparts have been signed by each of the parties and delivered
to the other parties, it being understood that all parties need not sign the
same counterpart.
