Changes in Registrant's Certifying Accountant. Effective March 10, 2006, the Audit Committee of the Board of Directors of Griffon Corporation (the "Company") dismissed PricewaterhouseCoopers LLP ("PWC") as the Company's independent registered public accounting firm and appointed Grant Thornton LLP ("Grant Thornton") as the Company's independent registered public accounting firm. PWC's reports on the financial statements of the Company for the fiscal years ended September 30, 2004 and 2005 contained no adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principle. During the fiscal years ended September 30, 2004 and 2005 and through March 10, 2006, there have been no disagreements with PWC (as defined in Item 304(a)(1)(iv) of Regulation S-K) 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 PWC, would have caused them to make reference thereto in their report on the financial statements for such years. During the fiscal years ended September 30, 2004 and 2005 and through March 10, 2006 there were no reportable events as defined in Regulation S-K Item 304 (a)(1)(v).

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 financial statements, and neither was a written report provided to the Company nor was oral advice provided that Grant Thornton concluded was an important factor considered by the Company in reaching a decision as to an accounting, auditing or financial reporting issue; or 2. Any matter that was either the subject of a disagreement or a reportable event, as each term is defined in Items 304(a)(1)(iv) and (v) of Regulation S-K, respectively. Item 9.01. Exhibits.
