          MILLENNIUM CHEMICALS REPORTS FIRST QUARTER OPERATING RESULTS
                 AND SCHEDULES INTERNET WEBCAST/TELECONFERENCE

                     -- 1Q04 net loss of $0.16 per share --
        -- 1Q04 net loss of $0.05 per share excluding designated items --

Hunt Valley, Maryland, May 14, 2004 -- Millennium Chemicals (NYSE-MCH)
("Millennium", or the "Company") today reported a net loss for the first quarter
of 2004 of $10 million or $0.16 per common share. For the corresponding quarter
of 2003, Millennium reported a net loss of $27 million or $0.43 per common
share. Excluding designated items(1), the first quarter 2004 net loss was $3
million or $0.05 per common share compared to a loss of $23 million or $0.36 per
common share for the corresponding quarter of 2003.(2)

The Company's adoption of revised FASB Interpretation No. 46, "Consolidation of
Variable Interest Entities", which was effective January 1, 2004 for certain
variable interests acquired before February 1, 2003, had no impact on the
Company's consolidated financial statements.




--------

(1) Designated items for the first quarter of 2004 include $6 million ($4
million after tax) of expenses related to an increase in legal and environmental
contingency liabilities for predecessor businesses, $3 million ($2 million after
tax) of costs related to the proposed business combination with Lyondell
Chemical Company, and $1 million ($1 million after tax) of reorganization costs
related to the Company's cost reduction program announced in July 2003.
Designated items for the first quarter of 2003 include $4 million ($3 million
after tax) for the Company's share of Equistar's loss on sale of assets and $1
million for the cumulative effect of the accounting change for asset retirement
obligations.

(2)  See Table V below for an explanation and quantification of these items, and
     a reconciliation between loss per common share, as adjusted for these
     designated items, and loss per common share determined according to
     accounting principles generally accepted in the United States of America.






Robert E. Lee, President and CEO, said, "Financial results for all three
majority-owned businesses and Equistar were improved from the prior quarter. We
continue to be optimistic that, with the improved economy, improving global
demand for our products and our continued focus on our customers and costs, our
momentum toward overall profitability should continue into the second quarter."

Operating income from majority-owned businesses was $13 million in the first
quarter of 2004. This compares to $27 million of operating income in the first
quarter of 2003 and a $97 million operating loss in the fourth quarter of 2003,
which included $103 million of asset impairment charges. Sales from all
majority-owned businesses were $465 million in the first quarter of 2004
compared to $415 million in the first quarter of 2003 and $425 million in the
fourth quarter of 2003. The decrease in operating income from the first quarter
of 2003 was due to reduced Titanium Dioxide segment profitability. The increase
in operating income in the first quarter of 2004 compared to the prior quarter,
which included $103 million of asset impairment charges, was due to improved
Titanium Dioxide business results.

During the first quarter of 2004, Millennium incurred approximately $3 million
of expenses relating to the proposed business combination with Lyondell Chemical
Company. These expenses relate primarily to fees for outside legal counsel and
financial advisors. The transaction is subject to customary conditions including
approval by both companies' shareholders, and is expected to close in the third
quarter of 2004.

TITANIUM DIOXIDE

The Titanium Dioxide segment reported first quarter 2004 operating income of $12
million compared to $21 million of operating income in the first quarter of last
year and $102 million of operating loss in the fourth quarter of 2003. Compared
to the first quarter of 2003, operating income was lower due to higher costs of
goods sold, only partially offset by additional profit from higher sales volume.
Operating income in the first quarter of 2004 was higher than the fourth quarter
of 2003 due to higher sales volume and lower costs of goods sold, only partially
offset by lower pricing.

The first quarter 2004 manufacturing costs per metric ton increased 1 percent
compared to the first quarter of 2003 primarily due to unfavorable currency
exchange rates, partially offset by lower energy and raw material costs and
higher plant operating rates. Manufacturing costs per metric ton in the first
quarter of 2004 decreased 4 percent compared to the fourth quarter of 2003
primarily due to higher operating rates and lower raw material costs and
maintenance spending, partially offset by unfavorable currency exchange.

ACETYLS

The Acetyls segment reported first quarter 2004 operating income of $9 million
compared to $7 million in the first quarter of last year and $9 million in the
fourth quarter of 2003.






SPECIALTY CHEMICALS

The Specialty Chemicals segment returned to profitability in the first quarter
of 2004 with operating income of $2 million equaling last year's first quarter
and exceeding the operating loss of $1 million in the fourth quarter of 2003.

DEBT AND CAPITAL SPENDING

Net debt (total debt less cash) at March 31, 2004 totaled $1.224 billion versus
$1.258 billion at December 31, 2003. The $34 million reduction in net debt
during the first quarter of 2004 was primarily due to a decrease of $22 million
in trade working capital. Net interest expense was $25 million in the first
quarter of 2004 compared to $22 million in the first quarter of 2003.

Capital spending in the first quarter of 2004 was $10 million compared to $8
million in the first quarter of 2003. Planned capital spending in 2004 is
projected to be approximately $60 million. Depreciation and amortization expense
in the first quarter was $24 million compared to $27 million in the first
quarter of 2003. The lower depreciation and amortization charge was primarily
due to the writedown of property, plant and equipment at the Company's Le Havre
TiO[u]2 manufacturing plant in the fourth quarter of 2003. Asset impairment
charges recorded in the first quarter of 2004 reflect the write-off of capital
spending at the Le Havre TiO[u]2 manufacturing plant during the quarter.

The statements in this press release that are not historical facts are, or may
be deemed to be, "forward-looking statements" as defined in the Private
Securities Litigation Reform Act of 1995. Some of these statements can be
identified by the use of forward-looking terminology such as "prospects,"
"outlook," "believes," "estimates," "intends," "may," "will," "should,"
"anticipates," "expects" or "plans," or the negative or other variation of these
or similar words, or by discussion of trends and conditions, strategy or risks
and uncertainties. In addition, from time to time, Millennium or its
representatives have made or may make forward-looking statements in filings that
Millennium makes with the Securities and Exchange Commission, in press releases
or in written or oral statements made by or with the approval of one of its
authorized executive officers. These forward-looking statements are only present
expectations reflecting current assumptions about future events. Actual events
or results may differ materially. Factors that could cause such a difference
include: the cyclicality and volatility of the chemical industries in which
Millennium and Equistar Chemicals, LP ("Equistar") operate, particularly
fluctuations in the demand for ethylene, its derivatives and acetyls and the
sensitivity of these industries to capacity additions; general economic
conditions in the geographic regions where Millennium and Equistar generate
sales, and the impact of government regulation and other external factors, in
particular the events in the Middle East; the ability of Equistar to distribute
cash to its partners and uncertainties arising from Millennium's minority
interest in Equistar, and Millennium's contractual commitments regarding
possible future capital contributions to Equistar; changes in the cost of energy
and raw materials, particularly natural gas and ethylene, and Millennium's and
Equistar's ability to pass on cost increases to their respective customers;
Millennium's substantial indebtedness and its impact on Millennium's cash flow,
business operations and ability to obtain additional financing -- failure to
comply with the covenants and other restrictions in Millennium's debt
instruments would lead to additional restrictions and costs, or an acceleration
of Millennium's indebtedness; limitations on credit extended to Millennium and
demands from creditors and suppliers for additional credit restrictions or
security; the ability of raw material suppliers to fulfill their commitments;
the ability of Millennium and Equistar to achieve their productivity
improvement, cost reduction and working capital targets, and the occurrence of
operating problems at manufacturing facilities of Millennium or Equistar; risks
of doing business outside the United States, including currency fluctuations;
the cost of compliance with the extensive environmental regulations affecting
the chemical industry and exposure to liabilities for environmental remediation
and other environmental matters relating to Millennium's and Equistar's current
and former operations; pricing and other competitive pressures; and legal
proceedings relating to present and former operations (including proceedings
based on alleged exposure to lead-based paints and lead pigments, asbestos and
other materials), ongoing and future tax audits, pension and retiree medical
costs, and other claims. A further description of these risks, uncertainties and
other matters can be found in Exhibit 99.1 to Millennium's Annual Report on Form
10-K for the fiscal year ended December 31, 2003, as amended and Lyondell's
registration statement containing the preliminary joint proxy statement/
prospectus in connection with the proposed business combination, which was
filed with the SEC on April 26, 2004. Millennium disclaims any obligation to
update any forward-looking statement, whether as a result of new information,
future events or otherwise.

In addition, in connection with the proposed business combination, Lyondell and
Millennium have filed relevant materials with the SEC, including a registration
statement containing a preliminary joint proxy statement/prospectus, which was
filed on April 26, 2004. The definitive joint proxy statement/prospectus will be
sent to holders of Lyondell's and Millennium's common stock when it becomes
available. Investors and security holders are urged to read the preliminary
joint proxy statement/prospectus
