ITEM 4.                    CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANTS.
                           -----------------------------------------------

         (a) Previous Independent Accountants

                  (i) On March 24,  2000,  the Board of  Directors  of  Advanced
Photonix,  Inc. (the "Registrant") decided to change independent accountants for
the fiscal year  beginning  March 29, 1999 and ending March 26, 2000 and thereby
dismissed Arthur Andersen LLP.

                  (ii) The reports of Arthur  Andersen  LLP on the  Registrant's
financial  statements  for the past two years ended March 28, 1999 and March 29,
1998  contained  no  adverse  opinion  or  disclaimer  of  opinion  and were not
qualified or modified as to uncertainty, audit scope or accounting principle.

                  (iii) In  connection  with its audits for the two most  recent
fiscal years and through March 24, 2000, there have been no  disagreements  with
Arthur  Andersen  LLP on any  matter  of  accounting  principles  or  practices,
financial  statement   disclosure,   or  auditing  scope  or  procedure,   which
disagreements, if not resolved to the satisfaction of Arthur Andersen LLP, would
have  caused them to make  reference  thereto in their  report on the  financial
statements for such years.

                  (iv) During the  registrant's two most recent fiscal years and
the subsequent  interim  period,  there were no reportable  events in accordance
with Item 304 (a)(1)(v) (A)-(D) of Regulation S-K.

                  (v) The Registrant delivered a copy of this Form 8-K report to
Arthur Andersen LLP on March 24, 2000.  Concurrently  therewith,  the Registrant
requested  that Arthur  Andersen  LLP furnish it with a letter  addressed to the
Securities and Exchange  Commission (the "SEC") stating whether or not it agrees
with the above statements. Attached hereto as Exhibit 16 is a copy of the letter
of Arthur Andersen LLP to the SEC dated March 28, 2000.

         (b) New Independent Accountants

                  (i) The Board of Directors of the  Registrant has approved the
engagement  of  Farber & Hass  LLP as its new  independent  accountants  for the
fiscal year ending March 26, 2000.  During the two most recent  fiscal years and
through March 26, 2000,  the Registrant has not consulted with Farber & Hass LLP
on items which  concerned  the subject  matter of a  disagreement  or reportable
event with the former auditor (as described in Regulation S-K Item 304 (a) (2)).
