CHLORINE
- --------
OXYCHEM COMMENTARY
- ------------------

o    Chlorine operating rates strengthened in the 1st quarter due to strong
     demand into the vinyl's chain. Industry operating rates increased
     approximately 1% in the 1st quarter 2004 versus the 4th quarter 2003.

o    OxyChem announced a $75 per ton price increase on January 27th , effective
     February 26th. Other U.S. chlor-alkali producers also announced a $75 per
     ton price increase in the 1st quarter.

o    Due to the tightening chlorine supply/demand balance, OxyChem announced and
     implemented a chlorine control program on March 15th.


                                                                              11

INFLUENCING FACTORS:
- --------------------

Industry operating rates are nearing practical capacity levels. Normal seasonal
increases in the bleach, water treatment and agricultural end use markets are
expected to push chlorine demand higher in the 2nd quarter.

CAUSTIC
- -------
OXYCHEM COMMENTARY
- ------------------
o    Caustic soda sales improved in the 1st quarter propelled by strong demand
     in the organic and alumina markets. Continuing improvement in the U.S.
     manufacturing sector also contributed to the overall increase in sales.

o    Demand for caustic soda is expected to improve in the 2nd quarter as the
     requirements for seasonal applications increase.

o    Pricing came under pressure in the 1st quarter due to high chlorine
     industry operating rates in support of increased vinyl's demand.

INFLUENCING FACTORS:
- --------------------
A narrowing supply/demand imbalance for liquid caustic soda will lend support
for future price improvement in 2004. Continued improvement in the U.S.
manufacturing sector is expected to result in higher caustic soda demand.
However, weakness in the manufacturing sector coupled with high chlorine
industry operating rates could prolong the supply/demand imbalance.

EDC
- ---
OXYCHEM COMMENTARY
- ------------------

o    EDC prices improved in the Far East early in the 1st quarter in conjunction
     with higher values for VCM and PVC.

o    A March pullback of PVC prices in China and uncertainty about future price
     movements stabilized the upward EDC price momentum experienced in the first
     part of the quarter.

o    While VCM and PVC remain tight, the current global EDC supply/demand
     position is balanced to long. As a result, EDC is relatively undervalued in
     comparison to the other intermediates in the vinyl's chain.

INFLUENCING FACTORS:
- --------------------
Higher PVC requirements in Asia, particularly China, are fueling demand for VCM
and EDC. However, despite the strong demand, Asian VCM production has been
curtailed


                                                                              12

due to both scheduled and unscheduled VCM plant outages. This situation has
negatively impacted EDC sales, resulting in a weaker than expected EDC
supply/demand balance. As no significant changes are expected in Asian VCM
production in the 2nd quarter, EDC demand is projected to remain flat.

PVC/VCM
- -------
OXYCHEM COMMENTARY
- ------------------

o    Domestic sales for PVC resin were strong in the 1st quarter in anticipation
     of seasonal demand for pipe and other exterior building products. Inventory
     throughout the vinyl's chain has remained moderate in comparison to 2003.

o    PVC resin exports were also strong during the 1st quarter, due primarily to
     demand from China.

o    Both the Westlake Geismar and Shintech Addis facilities remain idle. There
     is no indication that either plant will restart in 2004.

o    Industry operating rates for PVC resin during the 1st quarter were
     constrained due to scheduled and unscheduled VCM outages. OxyChem ran PVC
     resin at available capacity.

o    Domestic PVC resin prices increased $0.02 per pound in January versus
     December and another $0.02 per pound in both February and March. An
     additional $0.02 per pound increase has been implemented for April with
     $0.02 more announced for May. Higher sales prices have been necessary to
     offset higher ethylene and natural gas cost.

o    As a result of increased PVC demand and tight VCM supply, PVC resin export
     prices ended the quarter at $850 - $870 per metric ton CFR Southeast Asia.

o    The on-going VCM outages at Pemex and Dow contributed to a tight VCM supply
     during the 1st quarter. This tightness is expected to continue throughout
     the 2nd quarter as demand outpaces supply. As of early April, VCM
     inventories throughout the industry are at minimum levels

o    VCM export prices closed the 1st quarter at $640 - $660 per metric ton FOB
     Gulf Coast.

INFLUENCING FACTORS:
- --------------------
Strong global demand for PVC and VCM coupled with a tight VCM supply will
provide support for future price improvement throughout the vinyl's chain.
Continued economic recovery is expected to sustain a strong vinyl's business
environment through the 2nd quarter.
