ITEM 4.  CHANGE IN REGISTRANT'S CERTIFYING ACCOUNTANT.

         On April 28, 2000, Terremark Holdings, Inc., a Florida corporation
("Terremark"), merged with and into AmTec, Inc., a Delaware corporation
("AmTec"). Pursuant to the merger agreement, dated as of November 24, 1999, as
amended, AmTec was the surviving corporation, and its name has been changed to
Terremark Worldwide, Inc. ("Terremark Worldwide").

         Deloitte & Touche LLP ("D&T") was the certifying accountant for AmTec.
D&T was dismissed on the date the merger occurred, subject to completing the
audit of AmTec as discussed below. Correspondingly, PricewaterhouseCoopers, LLP
("PwC") was engaged by Terremark Worldwide as its principal accountants to audit
the Terremark Worldwide financial statements for the year ended March 31, 2001.
The engagement of PwC was made effective April 28, 2000.

         The decision to change independent accountants was not recommended or
approved by AmTec's board of directors or the audit committee of its board of
directors. However, the decision to retain one independent accounting firm was
made by the board of directors of Terremark Worldwide on April 28, 2000.

         D&T has been engaged to audit AmTec's March 31, 2000 financial
statements. During AmTec's two most recent fiscal years ended March 31, 1999,
there were no disagreements between management and D&T on any matter of
accounting principles or practices, financial statement disclosures, or auditing
scope or procedures, which disagreements, if not resolved to the satisfaction of
D&T, would have cause D&T to make reference to the subject matter of the
disagreement in connection with its report. In addition, the financial
statements of AmTec for such periods contained no adverse opinion or disclaimers
of opinion, and were not qualified or modified in any way. Also, during this
same period there were no reportable events as defined or listed in Item 304 of
Regulation S-K.

         D&T has furnished the registrant with a letter, filed herewith as
Exhibit 16, expressing its agreement with the representations made in this Form
8-K.
