ITEM 4. CHANGE IN REGISTRANT'S CERTIFYING ACCOUNTANT


On November 19, 2001, SI Diamond Technology, Inc. (the Registrant) notified
McGladrey & Pullen, LLP that they would no longer be the auditor for the
Registrant. At the same time, Sprouse & Winn L.L.P. was appointed as the
Registrant's new auditor effective November 19, 2001. The auditor's report from
McGladrey & Pullen, LLP for the Registrant's last fiscal year did not contain an
adverse opinion or a disclaimer of opinion, and was not qualified as to audit
scope or accounting principles. However, the auditor's report for the last
fiscal year was modified regarding the uncertainty of the Registrant's ability
to continue as a going concern. WallaceSanders & Company audited the 1999
financial statements. In August 2000 WallaceSanders & Company merged with
McGladrey & Pullen, LLP. McGladrey & Pullen, LLP was appointed as the
Registrant's new auditor effective September 6, 2000. The decision to engage
Sprouse & Winn L.L.P. as the successor to McGladrey & Pullen, LLP was
recommended and approved by the Registrant's Audit Committee of the Board of
Directors on November 19, 2001. During the Registrant's most recent fiscal year
and the subsequent interim period preceding the change, there have been no
disagreements with McGladrey & Pullen, LLP on any matter of accounting
principles or practices, financial statement disclosure, or auditing scope or
procedure. The Registrant has requested McGladrey & Pullen, LLP to furnish a
letter addressed to the Commission stating whether it agrees with the statements
made in this Item. Such letter is included in an exhibit to this Form 8-K.
