(A) Lyondell sold 8.28 million shares of common stock on July 1, 2002 in a
public offering and issued 34 million shares of Series B common stock
to Occidental on August 22, 2002 in connection with the purchase of
Occidental's 29.5% interest in Equistar.  Lyondell paid a dividend to
Occidental on June 30, 2003 by issuing 543,947 shares of Series B
common stock to Occidental in lieu of a dividend payment in cash.

Compared to the second quarter of last year, the net loss increased primarily as a result of reduced profitability of the Intermediate Chemicals and Derivatives (IC&D) segment, largely from a combination of the expiration of a significant MTBE contract at the end of 2002 and lower MTBE market margins. Compared to the first quarter of this year, the key factor that contributed to the improved results was higher Equistar ethylene margins, particularly for ethylene produced from liquid raw materials (see Note 1). This raw material advantage was largely responsible for an improvement of approximately $100 million in Equistar's net income. During the second quarter 2003, financings and restructuring costs reduced net income by $14 million or 9 cents per share. The year-to-date 2003 net loss increased to $181 million or $1.13 per share compared to a net loss of $53 million or 45 cents per share for the prior year-to-date period, primarily as a result of lower MTBE performance in IC&D and higher losses from the Company's Equistar ownership.

"Results during the quarter showed improvement when compared to the past two quarters, but were below the level that we anticipated when we entered the quarter," said Lyondell President and CEO Dan F. Smith. "Nonetheless, our continued focus on cash and liquidity allowed us to finish the second quarter with liquidity at Lyondell and Equistar at similar levels to those at the beginning of the year."

"Equistar's Gulf Coast olefin plants that can consume liquid raw materials demonstrated their differential cost advantage despite crude oil prices remaining stubbornly high, averaging close to $30 per barrel for the second quarter. This advantage was partially offset by depressed volumes in Equistar's products and across the chemical industry, caused by post-Iraq war inventory reductions, the impact of SARS, and generally poor economic conditions. In our 100%-owned IC&D segment, propylene oxide and derivatives performed as expected, realizing a series of price increases in April; but the MTBE business did not improve significantly. LYONDELL-CITGO Refining (LCR) continued to have excellent operating performance and strong cash distributions."

OUTLOOK

During the second quarter, product shipments in general demonstrated a slow but steady improvement, and thus far this trend has continued into the third quarter. The Company expects Equistar to continue to benefit from its liquid raw material advantage although to a somewhat reduced degree. IC&D has benefited from lower raw material costs thus far in the third quarter. The Company expects LCR's performance to continue to be strong, assuming sustained deliveries of contract crude oil volumes.

"Third quarter performance will be largely dependent on the pace of global economic recovery," Smith said. "Under a scenario of moderate economic recovery and improved global stability, we would expect both Lyondell and Equistar to benefit from strengthening volumes and moderating raw material prices. However, industry operating rates remain depressed and, therefore, it will be difficult to achieve and sustain margin improvements in the near term. The potential for continued raw material cost volatility represents an uncertainty for Equistar, but we believe that the fundamentals will continue to favor Equistar's liquid-based olefins position."

For IC&D, the second quarter 2003 included costs of $5 million related to financing activities.

2Q03 vs. 2Q02 -- Reduced profitability of MTBE accounted for the majority of the decrease in operating income versus the second quarter of 2002. The lower MTBE profitability resulted from a combination of the expiration of a favorable contract with BP at the end of 2002, higher raw material and utility costs related to high U.S. natural gas prices, and weak MTBE market conditions partially related to reduced demand in California. IC&D operating income was also impacted by increased operating costs, largely due to the new BDO-2 plant. Overall volumes for PO and derivatives, as well as TDI, were relatively unchanged versus the year ago period. Styrene profitability was relatively unchanged.

2Q03 vs. 1Q03 -- Compared to the first quarter of 2003, IC&D's operating loss improved by $12 million based on improved business results. PO and derivatives realized higher prices and margins in the second quarter but, as expected, this was offset by lower volumes driven by a seasonal decline in deicers and temporary shifts in demand patterns resulting from April 2003 price increases. MTBE benefited from increased sales volumes and moderately increased European margins while U.S. margins continued to be soft. Styrene showed moderate margin improvements, which were partially offset by reduced export volumes. However, TDI experienced both lower global sales volumes and lower European prices. Lyondell net income and IC&D EBITDA in first quarter 2003 included an $18 million gain related to the restructuring of the Nihon Oxirane joint venture in Asia.

Equistar Chemicals, LP -- Lyondell owns a 70.5 percent interest in Equistar, which consists of the petrochemicals and polymers segments.

Equistar's results in the second quarter 2003 included costs of $19 million related to financing activities.

2Q03 v. 2Q02 -- Compared to the second quarter of 2002, the current quarter was characterized by higher margins and lower volumes. The margin improvement primarily resulted from ethylene and polyethylene prices which were reported by Chemical Marketing Associates, Inc. (CMAI) to be an average 7 cents to 10 cents per pound higher than in the period a year ago. While purchased raw material prices were significantly higher for both liquid and natural gas-based raw materials in the second quarter of 2003, higher prices realized for Equistar's co-products produced from processing liquid raw materials offset most of the increase in liquid raw material prices. (See Note 2.)

CMAI, an industry consultant, estimates that the average cost of producing ethylene across the industry increased by approximately 3.5 cents per pound compared to the second quarter of 2002. However, as a result of Equistar's flexibility to process liquid raw materials, its equivalent costs only increased by approximately 2 cents per pound.

Offsetting the increased margins were reduced sales volumes of ethylene and derivative products (ethylene, ethylene oxygenates and polyethylene) which, when taken together, were 20 percent below year-ago levels. Polymer sales volumes also were negatively impacted by approximately 85 million pounds of lower polypropylene sales as a result of the first quarter 2003 sale of the Bayport polypropylene unit.

2Q03 v. 1Q03 -- Compared to the first quarter of 2003, Equistar's performance improvement was primarily a function of the lower cost of ethylene production at its Gulf Coast liquid-based olefin plants. This raw material advantage was largely responsible for an improvement of approximately $100 million in Equistar's net income. CMAI estimates that the average cost of producing ethylene across the industry decreased by approximately 5.4 cents per pound compared to the first quarter of 2003. However, as a result of Equistar's flexibility to process liquid raw materials, its equivalent costs decreased by nearly 8 cents per pound. Complementing this improvement, CMAI estimates that polymer pricing averaged 3 cents per pound higher than the first quarter average price. The positive impacts of the lower ethylene production costs and higher polymer prices were partially offset by significant volume reductions in ethylene and derivatives. Taken as a group, Equistar's ethylene and derivative products sales volumes were about 13 percent below first quarter 2003 sales levels. As noted above, Equistar's polymers sales volumes were impacted by the first quarter 2003 sale of the Bayport polypropylene unit.

LYONDELL-CITGO Refining LP (LCR) -- Lyondell owns a 58.75 percent interest in LCR, a major refiner of heavy crude oil.

LCR's second quarter results were reduced by a $6 million restructuring charge related to personnel reductions.

2Q03 v. 2Q02 -- Compared to the second quarter of 2002, performance at LCR was relatively unchanged. LCR's total crude processing rate increased by 15,000 barrels per day compared to the second quarter 2002, averaging 274,000 barrels per day. The amount of Venezuelan crude oil processed by LCR under the Crude Supply Agreement (CSA) with PDVSA was 45,000 barrels per day higher than in the second quarter of 2002, averaging 246,000 barrels per day. Offsetting these positives was the negative effect of higher gas costs and lower spot crude volumes.

2Q03 vs. 1Q03 -- In the first quarter of 2003, results were negatively impacted by a $25 million charge related to the restructuring of LCR's low sulfur gasoline project. Compared to the first quarter, total crude processing rates increased 28,000 barrels per day and CSA crude processing rates increased 52,000 barrels per day. Lower volumes and margins related to spot crude purchases partially offset the benefit of the higher CSA processing rates.

NOTE 1

"Liquid raw materials" include crude-oil-based liquids such as naphtha, condensates and gas oils. In contrast, "natural gas-based" raw materials include ethane, propane and butane which are sometimes referred to collectively as natural gas liquids (NGL's). Equistar's olefins facilities on the Texas Gulf Coast generally have the flexibility to use significant percentages of either liquid or natural gas based raw materials for the production of ethylene.

NOTE 2

The use of liquid raw materials results in the production of co-products such as propylene, butadiene, benzene and toluene. The use of natural gas- based raw materials does not produce significant volumes of these co-product materials.

(A) Defined as the major controllable components of working capital --
receivables, inventories and payables.  Receivables sold are added
back for consistency as such amounts are included in sales and in the
sales per day calculation.  Management believes that this provides
useful information to investors because it reflects Lyondell's and
Equistar's responsibility for administration and collection of said
amounts.
(B) In March 2003, in consideration of discounts offered by Equistar for
early payment, Lyondell paid certain Equistar product invoices
totaling $23 million for product delivered in March 2003.  Such
amounts otherwise would have been expected to be paid in April 2003
and would have reduced days of working capital as of March 31, 2003 to
40 days.
(C) Days of working capital are calculated as adjusted working capital
divided by sales per day.
(D) In consideration of discounts offered to certain customers for early
payment for product delivered in June 2003, some receivable amounts
were collected in June 2003 that otherwise would have been expected to
be collected in July 2003, including $32 million from Occidental.  Had
such amounts been collected in July 2003, days of working capital as
of June 30, 2003 would have been 39 days.
(E) In consideration of discounts offered to certain customers for early
payment for product delivered in March 2003, some receivable amounts
were collected in March 2003 that otherwise would have been expected
to be collected in April 2003, including $23 million from Lyondell and
$46 million from Occidental.  Had such amounts been collected in
April 2003, days of working capital as of March 31, 2003 would have
been 37 days.
