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

o    Seasonal demand was hindered by milder and wetter weather. This negatively
     impacted the bleach, water treatment and titanium dioxide market segments.

o    Pricing declined slightly in the 3rd quarter due to a slowdown in seasonal
     demand, increased global competition experienced by our customers, and a
     decline in industry operating rates.

o    Chlorine industry operating rates declined approximately 2% to 90% in the
     3rd quarter versus 2nd quarter 2003.


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

Industry operating rates are not expected to improve in the 4th quarter.


CAUSTIC
- -------
OXYCHEM COMMENTARY
- ------------------
o    Demand for caustic soda declined marginally in the 3rd quarter due to
     reduced volume into the pulp and paper and refining markets. Caustic soda
     demand is expected to ease further throughout the 4th quarter due to
     seasonality.

o    The price increase of $50 per ton announced for July 1st was unsuccessful.
     Strong competitive activity and the influence of significant increases in
     imported caustic brought pricing under pressure and adversely impacted the
     implementation of the price increase.

INFLUENCING FACTORS:
- --------------------
The supply/demand balance for caustic soda remains fragile. Industry capacity
rationalization and improvement in the U.S. manufacturing sector would provide
support for future price improvement. However, elevated chlorine operating rates
and increased imports could negatively impact future caustic price increases
during periods of weak demand.


EDC
- ---
OXYCHEM COMMENTARY
- ------------------
o    EDC values remained flat in the 3rd quarter in spite of improved VCM and
     PVC demand in the Far East.


                                                                              13

o    Unplanned and extended VCM outages in the US and Asia have weakened the EDC
     supply/demand balance. This is expected to continue throughout the 4th
     quarter.


INFLUENCING FACTORS:
- --------------------
PVC production in China via the calcium carbide process has negatively impacted
EDC demand and diluted some of the anticipated growth in 2003.


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

o    Reduced 2nd quarter customer inventories and favorable weather led to an
     improvement in 3rd quarter PVC sales demand. Inventories are at moderate
     levels going into the 4th quarter.

o    VCM outages in the U.S. and Asia allowed for price increases at the end of
     the 3rd quarter and will support price stability in the 4th quarter.

o    Capacities still exclude the former Borden Geismar and Addis facilities,
     which remain idle. There is little indication that either plant will
     restart in 2004.

o    July PVC pricing was down $.01/lb with August holding steady. The September
     increase of $.02/lb has been supported in the marketplace.

o    Demand and pricing for PVC exports improved slightly in the 3rd quarter due
     mostly to outages in Asia. 3rd quarter pricing ended at $650/MT.

o    The VCM market is tight with Pemex and Dow currently in an outage and PHH
     Lake Charles resuming production following their outage. OxyVinyls should
     benefit with increased 4th quarter sales.

INFLUENCING FACTORS:
- --------------------
Increased demand in both the domestic and export markets led to improved 3rd
quarter margins. 4th quarter margins will be dependant on continued demand and
raw material balances.


                                                                              14
