TELE CENTRO OESTE CELULAR PARTICIPACOES S.A. ("TCO") and TELESP CELULAR
PARTICIPACOES S.A. ("TCP" and, collectively with TCO, the "Companies") hereby
provide the following information with respect to the merger of shares of TCO
into TCP for the conversion of TCO into TCP's wholly-owned subsidiary ("Merger
of Shares"):

At a meeting held on December 26, 2003, the Brazilian Securities and Exchange
Commission - CVM opined to the effect that the Merger of Shares "violates
applicable laws".

After having reviewed the decision of CVM, the Companies continue to understand
that the transaction was structured, disclosed and is proposed to the
shareholders in compliance with the applicable laws, in addition to awarding an
equal treatment to the shareholders concerned. For this reason, the managements
of both Companies will review the situation in order to issue a recommendation
to their shareholders as to the Merger of Shares. Until such time, the Companies
have decided to suspend the shareholders' meetings scheduled for
January 7, 2004.

                          Sao Paulo, December 29, 2003.
