Item 5. Other Events

Pennzoil-Quaker State Company ("PQS") is restating its financial results for the
quarters ended September 30, June 30 and March 31, 2001, for each quarter in the
year ended December 31, 2000, and for the years ended December 31, 2000 and
1999.

As a result of this restatement, net income of PQS for the years ended December
31, 2000 and 1999 was reduced by $1.6 million ($.02 per share) and $0.6 million
($0.0 per share), respectively, while net income for the quarters ended
September 30, June 30, and March 31, 2001 was reduced by $0.6 million ($.01 per
share), $0.1 million ($0.0 per share), and $ 0.4 million ($0.0 per share),
respectively. The restatement does not affect reported cash flow or cash flows
from operations.

The restatement results from an error in the consolidated financial statements
of Excel Paralubes ("Excel"), in which PQS and Conoco Inc. ("Conoco") are equal
partners. Excel operates a base oil processing facility located adjacent to
Conoco's refinery in Lake Charles, Louisiana. The facility is capable of
producing over 20,000 barrels per day of high-quality base oils, the base
ingredient in finished lubricants. Conoco operates the plant with support
positions staffed primarily by Conoco. PQS relies on Conoco for financial and
operating data relevant to Excel's operations. Under a co-products sale and
purchase agreement, certain co-products produced at an adjacent Conoco facility
are allocated between Excel Paralubes and Conoco based upon Excel's feed stream
flow rates and compositions. Excel recently determined that the measurements of
the allocation of co-products between Excel and Conoco had been in error since
the commencement of Excel's operations in 1997. The restatement is necessary as
a result of the error. Under the co-products agreement, no adjustment is
required for periods prior to 1999.

PQS accounts for its investment in Excel using the equity method. The
consolidated financial statements of Excel are audited by PriceWaterhouseCoopers
LLP and filed as part of PQS's Annual Report on Form 10-K. The reports of PQS's
auditors, Arthur Andersen LLP, relating to PQS's financial statements as of and
for the years ended December 31, 2000 and 1999 relied solely on the auditors'
reports of PriceWaterhouseCoopers LLP insofar as they related to the amounts and
disclosures included in the consolidated financial statements of Excel.
