(Attach Extra Sheets if Needed) In February 1999, PricewaterhouseCoopers LLP was engaged to audit the financial statements of the Pennzoil-Quaker State Company Thrift and Stock Purchase Plan (the "Plan") required to be included in the Annual Report on Form 11-K to which this Form 12b- 25 relates. On June 16, 1999 Pennzoil-Quaker State Company was informed by a representative of PricewaterhouseCoopers LLP that that firm would be unable to express an opinion on the financial statements of the Plan because PricewaterhouseCoopers had not determined that they were independent with respect to the Plan under the standards of the American Institute of Certified Public Accountants and Section 2-01(b) of Regulation S-X. Thereupon, Pennzoil-Quaker State Company engaged Arthur Andersen LLP to perform the audit. Because of the short time available following the determination that the accounting firm originally engaged would be unable to provide an opinion and the engagement of another accounting firm to perform the audit, there is insufficient time to complete the audit prior to the date on which the Form 11-K is due. Accordingly, the Annual Report on Form 11-K cannot be filed by the date on which it is due without unreasonable effort or expense. - ------------------------------------------------------------------ Part IV -- Other Information - ------------------------------------------------------------------ (1) Name and telephone number of person to contact in regard to this notification Michael J.
