PRESS RELEASE

TRICOM ANNOUNCES $70 MILLION EQUITY INVESTMENT

SANTO DOMINGO, Dominican Republic, Jan 2, 2003/PRNewswire-FirstCall via COMTEX/
- -- TRICOM, a regional integrated communications provider in the U.S., Caribbean
and Central America, today announced a $70 million equity investment from a
group of private investors, led by Arturo Pellerano, the company's chairman and
chief executive officer.

The full amount of the proceeds will be used to repay short-term debt reducing
the company's interest requirements. Tricom will issue 21,212,121 shares of the
company's Class A common stock at a price of $3.30 per share. After the
investment, the company will have 64,602,585 total shares outstanding, including
45,458,041 Class A shares. The new equity investment is part of a comprehensive
effort to strengthen the company's capital structure.

During 2002 the company refinanced approximately $118 million of short- term
debt to long-term debt. On December 18, 2002, the company announced that it
intends to offer to exchange new debt securities for the entire $200 million
aggregate outstanding principal amount of its 11-3/8% Senior Notes due 2004. A
registration statement relating to the securities offered in the exchange offer
has been filed with the Securities and Exchange Commission but has not yet
become effective.

This press release is not an offer to sell or the solicitation of an offer to
buy any of the securities to be issued in the exchange offer described above nor
shall there be any sale of these securities in any jurisdiction in which such
offer, solicitation or sale would be unlawful prior to registration or
qualification under the securities laws of any such jurisdiction. The company
expects to commence the exchange offer promptly after the registration statement
is declared effective by the Securities and Exchange Commission.

The securities to be sold in the private placement have not been registered
under the Securities Act of 1933, as amended (the "Securities Act"), and may not
be offered or sold in the United States unless registered under the Securities
Act or an applicable exemption from registration is available. This press
release does not constitute an offer to sell or the solicitation of an offer to
buy, nor shall there be any sale of these securities in any state in which such
offer, solicitation or sale would be unlawful prior to the registration or
qualification under the securities laws of any such state.
