CHLORINE

OxyChem Commentary

•	Industry operating rates were impacted by normal seasonality in the chlorinated derivative and vinyls demand. Downstream chlorinated derivative inventories remain at minimum levels in the expectation that both raw material and energy costs could ease. Uncertainty regarding domestic and export demand in 2006 has also contributed to lower downstream inventory levels.

•	The normal seasonal slowdown in chlorine demand during the 1^st quarter resulted in increased competitive pricing activity. Chlorine market prices moved lower during the 1^st quarter, negating the impact of the $25 per ton price increase announced in the 3^rd quarter of 2005.

Investor Relations Supplemental Schedules

•	OxyChem announced a $25 per ton price increase effective March 22^nd or as contract terms permit. Other U.S. chlor-alkali producers have announced similar increases. This increase is in response to a tightening supply/demand balance expected in the 2^nd quarter of 2006.

•	OxyChem anticipates improved 2^nd quarter operating rates due to stronger demand in the vinyls, bleach, MDI/TDI and derivative markets.

Influencing Factors:

All operating issues related to the 2005 hurricanes have been corrected for chlorine producers and consumers. Chlorine demand has improved moving into the 2^nd quarter with the expectation that the supply/demand balance will tighten in the 2^nd and 3^rd quarters. Gulf Coast rebuilding should begin to have a positive impact on chlorine demand starting in the 2^nd quarter, further tightening the supply/demand balance.

CAUSTIC

OxyChem Commentary

•	OxyChem’s liquid caustic soda sales volume declined in the 1^st quarter vs. the 4^th quarter of 2005 due to normal seasonal weakness. Sales are expected to improve in the 2^nd quarter as seasonal demand improves.

•	Pricing for liquid caustic soda came under pressure in the 1^st quarter due to imports and seasonally low demand as the market continued to recover from the effects of the 2005 hurricanes and historically high caustic soda pricing.

•	OxyChem anticipates imports to return to more moderate levels in the 2^nd quarter as the global supply/demand balance narrows and the U.S. Gulf Coast production returns to normal operating status.

Influencing Factors:

Demand for liquid caustic soda is expected to improve in the 2^nd quarter narrowing the supply/demand balance. As a result, pricing is expected to stabilize in the 2^nd quarter. However, unseasonably cool weather, increased imports or unfavorable changes in the U.S. manufacturing sector could impact the supply/demand balance and exert some pressure on 2^nd quarter pricing.

EDC

OxyChem Commentary

•	EDC price improved slightly in the middle of the 1^st quarter but fell back to 2005 end-of-year values by the end of the quarter as demand softened.

Investor Relations Supplemental Schedules

•	EDC prices ended the 1^st quarter at $310-$330 per metric ton CFR Asia and are expected to further decline in April.

•	Balances remained long in the 1^st quarter as Asian PVC demand was weaker than anticipated. Producers opted to slow PVC and VCM production rather than buy EDC and sell their product at low values.

Influencing Factors:

Demand for U.S. EDC exports will remain limited. Small fluctuations may be seen in EDC price but significant gains are not expected as PVC demand in Asia is not strong enough to overcome the economic advantage of calcium carbide based VCM production.

PVC/VCM

OxyChem Commentary

•	Declines in ethylene and natural gas resulted in expanding PVC spreads as PVC prices eroded at a slower pace.

•	Anticipation of lower PVC pricing due to declining feedstock costs moderated the normal seasonal build up in downstream PVC inventory. Buyers continued to focus on maintaining low inventories and selling higher cost inventory purchased in the 4^th quarter 2005.

•	Domestic PVC resin prices were flat in January before declining $0.015 per pound in February and an additional $0.02 per pound in March. OxyVinyls announced a $0.02 per pound price increase effective April 1^st.

•	Due to attractive domestic PVC margins, spot activity was elevated in the 1^st quarter.

•	The Scotford PVC plant in Alberta, Canada was shut down at the end of January due to the lack of an economical supply of VCM.

•	PVC resin export prices ended the quarter at $720 - $730 per metric ton CFR Southeast Asia.

•	Due in part to the influence of Asian PVC in the Latin American market, the U.S. export spot VCM price to Latin America ended the quarter at $700 per metric ton FOB U.S. Gulf Coast.

•	Asian VCM prices ended the quarter at $600 per metric ton CFR, an increase of $50 per metric ton from year end 2005. With the continued high freight rates and ethylene cost, this price was not economical for U.S. producers. Since January, U.S. producers have began supplying Latin America based on lower energy cost.

Investor Relations Supplemental Schedules

Influencing Factors:

PVC demand was seasonally slow in the 1st quarter. It is believed that the lackluster demand is a result of anticipated lower domestic PVC pricing due to sharp declines in feedstock costs. Vinyls demand is expected to improve in the 2nd quarter as the spring construction season begins. Dow’s permanent closure of the Fort Saskatchewan VCM facility is expected to tighten the VCM supply/demand balance in the Americas.
