Employer jurisdiction Identification No.) of incorporation) 41920 Christy Street, Fremont, California 94538-3158 (Address of principal executive offices) (510) 657-2635 (Registrant's telephone number, including area code) ITEM 4. CHANGES IN REGISTRANT'S CERTIFYING ACCOUNTANTS. On September 10, 2002, Digital Power Corporation (the "Registrant") engaged the accounting firm of Ernst & Young, as its independent certifying accountants for the remainder of the fiscal year ending December 31, 2002, including preparation of the audit and Form 10-KSB for the fiscal year ended December 31, 2002. On that same date, the Registrant notified Hein + Associates LLP of their dismissal. Hein + Associates LLP was the independent certifying accountant previously engaged to audit the Registrant's financial statements for the fiscal years and periods ended December 31, 2000 and December 31, 2001. The decision to change accountants was approved by the Audit Committee and the full Board of Directors of the Registrant. During the Registrant's two most recent fiscal years and periods ended December 31, 2000 and December 31, 2001 and the subsequent interim period through September 10, 2002, there were no disagreements between the Registrant and Hein + Associates LLP on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedures, which disagreements if not resolved to their satisfaction would have caused them to make reference in connection with their opinion to the subject matter of this disagreement. None of the "reportable events" described under Item 304(a)(1) of Regulation S-KB occurred within the Registrant's two most recent fiscal years and the subsequent interim period through September 10, 2002. The audit report of Hein + Associates LLP on consolidated financial statements of the Registrant and subsidiaries as of and for the fiscal years and periods ended December 31, 2000 and December 31, 2001, did not contain any adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles. The Registrant requested Hein + Associates LLP furnish a letter to the Registrant addressed to the Securities and Exchange Commission stating whether it agrees with the above. A letter from Hein + Associates LLP is attached as Exhibit 16.1. During the Registrant's two most recent fiscal years and periods ended December 31, 2000 and December 31, 2001 and the subsequent interim period through September 10, 2002, the Registrant did not consult with Ernst & Young regarding any of the matters or events set forth in Item 304(a)(2)(i) and (ii) of Regulation S-KB.
