ITEM 5. Other Events.

         On April 14, 1998, Quaker State Corporation, a Delaware corporation
(the "Company"), Pennzoil Company, a Delaware corporation ("Pennzoil"),
Pennzoil Products Company, a Delaware corporation and a wholly owned subsidiary
of Pennzoil ("PPC"), and Downstream Merger Company, a Delaware corporation and
a wholly owned subsidiary of PPC ("Merger Sub"), entered into an Agreement and
Plan of Merger (the "Merger Agreement").  The Merger Agreement and related
agreements provide for the separation of Pennzoil's motor oil, refined products
and franchise operations from its exploration and production operations and for
the combination of the motor oil, refined products and franchise operations
with the Company.

         The transactions contemplated by the Merger Agreement are (1) a pro
rata distribution, on a share for share basis, of all of the issued and
outstanding Common Stock of PPC to the holders of Common Stock of Pennzoil to
be followed by (2) a merger of Merger Sub with and into the Company, in which
holders of Capital Stock of the Company will receive, in exchange for each
share held, 0.8204 shares of Common Stock of PPC.  Immediately following the
transactions contemplated by the Merger Agreement, approximately 38.5% of PPC
will be owned by former Company stockholders and approximately 61.5% of PPC
will be owned by stockholders of Pennzoil.  The name of PPC will be changed
prior to or in connection with the merger to a new name to be determined.

         Closing under the Merger Agreement is conditioned on, among other
things, approval by the Company's stockholders, expiration or termination of
waiting periods under the Hart-Scott-Rodino Antitrust Improvements Act of 1976,
and receipt of a tax ruling from the Internal Revenue Service.

         A copy of the Merger Agreement is filed as Exhibit 2.1 hereto and is
incorporated herein by this reference.  On April 15, 1998, the Company and
Pennzoil issued a press release announcing the execution of the Merger
Agreement.  A copy of the press release is filed as Exhibit 99.1 hereto and is
incorporated herein by this reference.  The foregoing summary does not purport
to be complete and is qualified in its entirety by reference to such documents.
