New York Stock Exchange Advises Tricom that Its Stock
Has Fallen Below Minimum Listing Criterion

        SANTO DOMINGO, Dominican Republic—Tricom, S.A. (NYSE: TDR) today announced that it has been notified by the New York Stock Exchange (NYSE) that its American Depository Receipts (ADRs) are below the criterion for continued listing because the average closing price of its ADRs for a consecutive 30-day period beginning October 21, 2003, was below $1.00.

        Under NYSE guidelines, the Company must return its share price and average share price back above $1.00 by six months following receipt of the NYSE's notification. In the event that the Company fails to return to compliance during this time period, the NYSE has notified the Company that it will commence suspension and delisting procedures for the Company's ADRs.

        In accordance with NYSE rules, the Company has acknowledged to the NYSE receipt of this notification and its intention to cure this deficiency. There can be no assurance, however, that the Company will be able to do so. The closing price for Tricom's ADRs on February 9, 2004 was $1.64.
