New York (April 28, 2000) - The stockholders of AmTec, Inc., an international
telecommunications services company, approved today its merger with Terremark
Holdings Inc., a full service real estate and development company, during the
shareholders meeting held at 10:00 AM at the Waldorf Astoria. The newly combined
company is TERREMARK WORLDWIDE, INC., which has its headquarters in the
Terremark Centre in Miami, Florida, with offices in several other locations,
including New York and Washington, D.C.. Terremark will continue the focus of
its predecessors by aggressively pursuing opportunities domestically and in
emerging markets in both telecommunications and real estate, as well as
resulting synergies, like the expansion of its T-Rex brand of telcom hotels.
Starting May 1, Terremark Worldwide will be traded on the American Stock
Exchange under the symbol TWW.

At TWW's first meeting of the new Board of Directors, Manuel D. Medina was
elected Chairman of the Company and also appointed President and CEO. Commenting
on the future of the Company, Mr. Medina remarked, "The fundamentals that have
made Terremark Holdings highly successful as a diversified real estate services
company over the last twenty years, combined with the essential elements AmTec
brings into the fold will serve TERREMARK WORLDWIDE well in the geometrically
expanding telecommunications industry. Those fundamentals include dedication,
team work, creativity and a commitment to excellence in all endeavors."

In addition, the TWW Board also ratified the Company's contract to acquire
Telecom Routing Exchanging Developers, Inc. (also known as "T-Rex"). With the
Board's approval satisfying the sole remaining condition to completion of the
acquisition, the formal closing of that transaction is expected in the next 7-10
days.
