Item 4.   Change in Registrant's Certifying Accountant

     On October 21, 2003 Ultradata dismissed Weinberg & Company, P.A., C.P.A.
("Weinberg") from its position as Ultradata's principal independent
accountant.  The decision to change accountants was approved by Ultradata's
Board of Directors, upon recommendation by its Audit Committee.
     The audit reports of Weinberg on Ultradata's financial statements for
the years ended December 31, 2002 and 2001 contained a modification expressing
substantial doubt about Ultradata's ability to continue as a going concern.
The audit reports of Weinberg for the years ended December 31, 2002 and
2001 did not contain any other adverse opinion or disclaimer of opinion or
qualification other than the modification noted above.  Weinberg did not,
during the applicable periods, advise Ultradata of any of the enumerated items
described in Item 304(a)(1) of Regulation S-B.
     Ultradata and Weinberg have not, in connection with the audits of
Ultradata's financial statements for the years ended December 31, 2002 or
December 31, 2001, had any disagreement on any matter of accounting principles
or practices, financial statement disclosure, or auditing scope or procedure,
which disagreement, if not resolved to Weinberg's satisfaction, would have
caused Weinberg to make reference to the subject matter of the disagreement in
connection with its reports.
     On October 24, 2003, Ultradata retained the firm of Webb & Company, P.A.
to audit Ultradata's financial statements for the year ended December 31,
2003.  At no time during the past two fiscal years or any subsequent period
did Ultradata consult with Webb & Company, P.A. regarding either the
application of accounting principles to a specified transaction or the type of
audit opinion which might be rendered on Ultradata's financial statements or
any matter of the sort described above with reference to Weinberg.
