Item 4.01. Changes in Registrant’s Certifying Accountant.

On March 31, 2005, the Audit Committee of the Board of Directors of MASSBANK Corp. (the “Company”) replaced KPMG LLP (“KPMG”) as the Company’s independent registered public accountants with Parent, McLaughlin & Nangle. KPMG resigned as the Company’s independent registered public accountants as of such date. The reports issued by KPMG on the Company’s financial statements for each of the past two fiscal years did not contain an adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles. During the Company’s two most recent fiscal years and through the date hereof, there were no disagreements with KPMG on any matter of accounting principle or practice, financial statement disclosure or auditing scope or procedure, which, if not resolved to KPMG’s satisfaction, would have caused them to make reference to the subject matter in connection with their report of the Company’s financial statements for such years; and there were no “reportable events” as defined in Item 304(a)(1)(v) of Regulation S-K.

The Company provided a copy of the foregoing disclosure to KPMG prior to the filing of its original report regarding the change in Certifying Public Accountant on Form 8-K on April 5, 2005. Attached as Exhibit 16.1 hereto is a copy of a letter from KPMG dated April 8, 2005 stating that KPMG agrees with such statements.

On March 31, 2005, the Company engaged Parent, McLaughlin & Nangle to serve as the Company’s independent registered public accountants for the fiscal year ended December 31, 2005. During the fiscal years ended December 31, 2004 and December 31, 2003, and through the date hereof, the Company did not consult with Parent, McLaughlin & Nangle with respect to the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s consolidated financial statements, or any other matters or reportable events as set forth in Items 304(a)(2)(i) and (ii) of Regulation S-K.
