Change in the Registrant's Certifying Accountant On April 10, 2002, Core Laboratories N.V. ("Core Laboratories" or the "Company") decided to no longer engage Arthur Andersen LLP ("Andersen") as the Company's independent public accountants and appointed PricewaterhouseCoopers LLP as its new independent auditors for 2002. This decision followed the Audit Committee's recommendation to seek proposals from independent public accountants with respect to the 2002 audit, and was approved by the Company's Board of Supervisory Directors. The decision to change auditors is not a reflection of Andersen's commitment or quality of service to the Company. During its seven year relationship with the Company, the Andersen team exhibited the highest degree of professionalism and quality service. Andersen's reports on Core Laboratories consolidated financial statements for each of the years ended December 31, 2001 and 2000 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 years ended December 31, 2001 and 2000 and through April 10, 2002, there were no disagreements with Andersen on any matter of accounting principle or practice, financial statement disclosure, or auditing scope or procedure which, if not resolved to Andersen's satisfaction, would have caused them to make reference to the subject matter in connection with their report on Core Laboratories consolidated financial statements for such years. During the years ended December 31, 2001 and 2000 and through April 10, 2002, there were no reportable events as listed in Item 304(a)(1)(v) of Regulation S-K within the two most recent fiscal years of the Company ended December 31, 2001. The Company provided Andersen with a copy of the foregoing disclosures. Attached as Exhibit 16 is a copy of Andersen's letter, dated April 26, 2002, stating its agreements with said statements. During the two most recent fiscal years of the Company ended December 31, 2001 and through the date hereof, the Company did not consult with PricewaterhouseCoopers LLP regarding any of the matters or events set forth in Item 304(a)(2)(i) and (ii) of Regulation S-K.
