[c]  Includes the dilutive effect of the convertible debentures, stock
options and warrants.

First-quarter 2007 results from continuing operations declined versus the fourth quarter 2006 due to the impact of scheduled maintenance on the Houston refinery's fluid catalytic cracking unit (FCCU), lower average prices and margins in the ethylene segment and a charge related to the 2005 Lake Charles TDI plant closure. Aside from this charge, propylene oxide segment results improved versus the fourth quarter 2006. The inorganic chemicals business results also improved versus the fourth quarter 2006.

Additionally, results reflect the following:

"As expected, refining results were negatively impacted by scheduled maintenance, but this work positions the refinery well for the coming years and the developing strong summer season," said Dan F. Smith, president and CEO of Lyondell Chemical Company. "Within our ethylene segment, the early months of the first quarter were quite challenging as product prices were slow to rebound from a fourth-quarter decline. However, sales volumes were quite strong, and positive pricing momentum returned in March and has continued in April. Hence, I don't see the first quarter's results as an indicator of the balance of the year. Rather, it is merely an example of the volatility created by energy prices."

OUTLOOK

The second quarter has shown increased strength, particularly in gasoline- related products, and chemical product prices also are displaying positive momentum. The refining segment is benefiting from seasonally strong margins; however, as previously reported, second-quarter results will be modestly impacted by the 10-day outage of the FCCU. The ethylene segment is benefiting from good demand and positive price momentum, although high and volatile crude oil prices continue to present a challenge. The propylene oxide segment has realized continued steady performance of the chemical products, while fuel products are responding to strong gasoline markets.

"Our outlook for our chemical and fuel businesses continues to be very positive. The prospects for the summer months are shaping up well, and our businesses are well positioned as we enter what appears to be another strong season in the fuels markets. As a result, our portfolio should demonstrate its strong earnings- and cash-generating capabilities," said Smith. "Additionally, the pending sale of the inorganic chemicals business will significantly accelerate our debt reduction and balance sheet improvement."

LYONDELL BUSINESS RESULTS DISCUSSION BY REPORTING SEGMENT

Lyondell operates in three segments: 1) Ethylene, co-products and derivatives; 2) Propylene oxide (PO) and related products; and 3) Refining. Inorganic chemicals is presented as a discontinued operation due to the pending sale of this business.

Ethylene, Co-products and Derivatives Segment - The primary products of this segment are ethylene, ethylene co-products (propylene, butadiene and benzene), and derivatives of ethylene (polyethylene, ethylene oxygenates and vinyl acetate monomer or VAM).

continuing operations.

1Q07 v. 4Q06 - Ethylene and ethylene derivative product sales volumes increased by approximately 150 million pounds (approximately 5 percent) versus the fourth quarter 2006. Compared with the fourth quarter, our quarterly average prices for ethylene and polyethylene decreased by approximately 2 cents per pound, and the ethylene glycol price was unchanged. The company's average cost-of-ethylene-production metric (COE) increased by approximately 3.5 cents per pound versus the fourth quarter primarily due to increases from crude-oil based raw materials. Acetyls results were relatively unchanged.

1Q07 v. 1Q06 - Ethylene and ethylene derivative product sales volumes were up approximately 85 million pounds versus the first quarter 2006. The quarterly average prices for ethylene and polyethylene decreased by approximately 8.5 cents and 13 cents per pound, respectively, and the ethylene glycol price was unchanged. The company's average COE metric was relatively unchanged. Acetyls results improved by approximately $25 million primarily as a result of increased margins as raw material costs declined while methanol sales prices increased.

PO and Related Products Segment - The principal products of the PO and related products segment include PO, PO derivatives (propylene glycol, propylene glycol ethers, butanediol and butanediol derivatives), styrene, fuel products (methyl tertiary butyl ether [MTBE] and ethyl tertiary butyl ether [ETBE]), isobutylene and toluene diisocyanate (TDI).

[b]  Operating income and EBITDA for the first quarter 2007 include a
pretax charge of $62 million related to commercial arrangements
associated with the 2005 shutdown of the Lake Charles
TDI facility.
[c]  See Table 10 for a reconciliation of segment EBITDA to income from
continuing operations.

1Q07 v. 4Q06 - Segment EBITDA decreased by $18 million versus the fourth quarter primarily due to the $62 million TDI charge. PO and PO derivative results increased by approximately $40 million due to increased margins and sales volumes. Fuel-product results increased moderately primarily due to increased sales volumes and the absence of fourth-quarter maintenance. Styrene results decreased moderately as a result of lower margins. TDI results declined by approximately $65 million primarily due to the $62 million charge.

1Q07 v. 1Q06 - Segment EBITDA decreased by $88 million versus the first quarter 2006 primarily due to the $62 million TDI charge. Fuel product results declined by approximately $20 million primarily due to lower margins partially related to export costs. Styrene results declined by approximately $20 million due to lower margins. PO and PO derivative results were comparable. TDI results declined by approximately $55 million primarily as a result of the $62 million charge, which was partially offset by increased prices.

Refining Segment - Lyondell owned a 58.75 percent interest in Houston Refining LP (formerly known as Lyondell-Citgo Refining LP) prior to Aug. 16, 2006, at which time Lyondell purchased the remaining 41.25 percent interest from CITGO Petroleum Corporation. Prior to Aug. 16, Lyondell's interest was accounted for by the equity method. As a result of the acquisition, Houston Refining's operations are consolidated from Aug. 16. The following review is on a 100-percent basis.

Refining.

1Q07 v. 4Q06 - Results were lower compared to the prior quarter, which included approximately $55 million of favorable effects. Those fourth-quarter effects included a $14 million insurance settlement and a $19 million benefit from a LIFO inventory decrement with the remainder due to other product inventory changes. Operationally, refining results in the first quarter 2007 were negatively impacted by approximately $140 million related to the planned maintenance turnaround and upgrade of the FCCU and related units. Of this amount, approximately $80 million is related to a 54,000-barrel-per-day reduction in average crude processing rates, $45 million is related to the inability to realize full conversion margins during the maintenance, and $15 million is related to increased operating costs. Lower aromatics results also impacted the quarter.

1Q07 v. 1Q06 - Results declined primarily due to the impact of the scheduled maintenance during the first quarter 2007. The maintenance impact was partially offset by a $3-per-barrel increase in the conversion margin. As a reminder, first-quarter 2006 results are based on the previous crude supply agreement rather than the current contract.

Discontinued Operations - Inorganic Chemicals The principal product of inorganic chemicals is titanium dioxide (TiO2). In view of the pending sale of the inorganic chemicals business, substantially all of the inorganic chemicals segment is being reported as a discontinued operation including comparative periods.

impairment of goodwill and certain software costs.
[c]  See Table 10 for a reconciliation of EBITDA to income (loss) from
discontinued operations, net of tax.

1Q07 v. 4Q06 - Sales volumes increased by approximately 10,000 metric tons versus the fourth quarter primarily due to improved operations. Average sales prices declined by approximately $16 per ton primarily due to lower North American prices. Costs declined by approximately $25 million due to improved operating reliability.

1Q07 v. 1Q06 - TiO2 sales volumes declined by approximately 5,000 metric tons versus the first quarter of 2006; however, this was offset by increased sales of titanium tetrachloride and ultrafine TiO2. TiO2 prices declined by $19 per ton. Costs increased by approximately $15 million, including some lingering effects of production issues from the fourth quarter 2006.

Cash Distributions and Debt Reduction

Equistar Chemicals, LP to Lyondell Chemical Company and Millennium Chemicals Inc. - During the quarter, Equistar distributed $70.5 million to Lyondell and $29.5 million to Millennium.

Millennium to Lyondell Chemical Company - There were no dividends paid by Millennium to Lyondell Chemical Company during the first quarter.

Debt Reduction - During the first quarter, there was no debt repayment except the scheduled amortization of term loans.

Receivable Facilities Utilization - As of March 31, 2007, Lyondell's receivable facility was utilized by $125 million and Equistar's receivable facility was unutilized.

[b]  The Refining information represents the operating results of Houston
Refining on a 100% basis.
[c]  In the first quarter 2007, Lyondell signed an agreement for a
pending sale of its worldwide inorganic chemicals business.  As a
result, the inorganic chemicals business is being reported as a
discontinued operation, including comparative periods presented.
[d]  As a result of Lyondell's acquisition of 100% of Houston Refining,
beginning with the fourth quarter 2006, Lyondell is providing
throughput margin per barrel information for the refining segment.
Throughput margin per barrel is a statistic that is commonly
reported by independent refiners, and management believes that it
provides useful information to help investors, financial analysts
and the public analyze and evaluate refining segment performance
compared to other refiners and to industry benchmarks.  Lyondell's
presentation of throughput margins for the refining segment should
not be considered as an alternative to GAAP measures such as
refining segment revenues and operating income.  See Table 14 for
calculation of throughput margin and reconciliation to Refining
segment operating income.  The throughput margin is divided by the
number of barrels of crude oil processed in the quarter to derive
the margin per barrel.
[e]  Market margins are reported by Platts, a division of The McGraw-Hill
Companies.
