                              for Fiscal Year 2000

     Camarillo,  CA - April 4, 2001 -- California Amplifier Inc. (Nasdaq:  CAMP)
today announced that as a result of procedures performed to date relating to its
continuing internal financial investigation the Company has confirmed that there
are  overstatements to net income for the fiscal year ended February 26, 2000 as
discussed  in it's press  release  dated March 29, 2001,  as well as  additional
overstatements  to net income for the  interim  quarterly  statements  issued in
fiscal year 2001. The amounts for each fiscal year,  however,  have not yet been
finalized.  To date, there has been no indication of any misstatement of revenue
for any  period,  and no  detection  of any  misappropriation  of cash or  other
assets.

As a result of these  findings  Arthur  Andersen LLP, the Company's  Independent
Public  Accountants,  has informed the Company that due to the  misstatements it
has  withdrawn its Report of  Independent  Public  Accountants  on the Company's
consolidated financial statements for the year ended February 26, 2000.

The Company is working diligently to conclude this  investigation,  and upon its
completion and re-certification of its financial statements for fiscal year 2000
by Arthur  Andersen  LLP, the Company will file  amendments to Form 10-K for its
fiscal year 2000 and the related  quarterly  Form 10-Qs for fiscal year 2000 and
fiscal year 2001.

Company's common stock to resume trading.
