Business Editors

CAMARILLO, Calif.--(BUSINESS WIRE)--April 4, 2002

California Amplifier, Inc. (Nasdaq: CAMP) today announced that its Board of Directors has appointed KPMG, LLP as the Company's independent auditor for its fiscal year ended February 28, 2002, replacing Arthur Andersen, LLP.

"We are pleased that KPMG will serve as California Amplifier's new auditor and look forward to building a long-term relationship with the firm," said Fred Sturm, President and Chief Executive Officer. "The appointment of KPMG as outside auditor for fiscal year 2002 was made after careful review and consideration. Arthur Andersen has provided professional services to California Amplifier since the Company's inception. However, in light of recent developments involving Arthur Andersen, we believe that engaging KPMG is in the best interest of California Amplifier and its shareholders."

Mr. Sturm continued, "As a result of the change in auditors, we anticipate reporting fourth quarter and fiscal year 2002 audited financial results in the second half of May 2002."

The Company also announced unaudited fourth quarter revenue of approximately $22.5 million, modestly above the high end of the $18 to $22 million sales guidance the Company provided in December 2001. Additionally, the Company currently anticipates fourth quarter earnings per share to be at or above the high end of the previous guidance of $.01 to $.04.
