Changes in Registrant's Certifying Accountant. On July 12, 2002, the Company dismissed Arthur Andersen LLP ("Arthur Andersen") as the independent public accountants of Dynamic Materials Corporation (the "Company") and, upon the recommendation of our Audit Committee, the Board of Directors approved the appointment of Ernst & Young LLP ("Ernst & Young") to serve as independent public accountants for the fiscal year ending December 31, 2002. The change in the Company's auditors is effective July 18, 2002. Arthur Andersen's report on the Company's consolidated financial statements for the year ended December 31, 2001 did not contain an adverse opinion or a disclaimer of opinion, nor was such report qualified or modified as to uncertainty, audit scope or accounting principles. During each of the Company's two most recent fiscal years and through the date of this report, there were: (i) no disagreements with Arthur Andersen on any matter of accounting principle or practice, financial statement disclosure, or auditing scope or procedure which, if not resolved to Arthur Andersen's satisfaction, would have caused them to make reference to the subject matter in connection with their report on the Company's consolidated financial statements for such year; and (ii) no reportable events as defined in Item 304(a)(1)(v) of Regulation S-K. We have requested Arthur Andersen to furnish us a letter addressed to the Securities and Exchange Commission stating whether it agrees with the above statements. A representative of Arthur Andersen has informed the Company that Arthur Andersen is no longer furnishing such letters. During each of the two most recent fiscal years and through the date of this report, the Company did not consult Ernst & Young 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.
