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").

         Prior to the transaction with Terremark, Deloitte & Touche LLP ("D&T")
was engaged by AmTec to perform the audit of AmTec's March 31, 2000 financial
statements. As a result of the transaction with Terremark,
PricewaterhouseCoopers, LLP ("PwC") was engaged by Terremark Worldwide as its
principal accountants to audit the Terremark Worldwide financial statements for
the year ending 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.

         During AmTec's two most recent fiscal years ended March 31, 2000, and
through June 29, 2000, the date of filing of the Annual Report on Form 10-K for
the year ended March 31, 2000, 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/A.
