Occidental's results of operations often include the effects of significant
transactions and events affecting earnings that vary widely and unpredictably in
nature, timing, and amount. Therefore, management uses a measure called "core
earnings", which excludes those items. This non-GAAP measure is not meant to
disassociate those items from management's performance, but rather is meant to
provide useful information to investors interested in comparing Occidental's
earnings performance between periods. Reported earnings are considered
representative of management's performance over the long term. Core earnings is
not considered to be an alternative to operating income in accordance with
generally accepted accounting principles.

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

o    As contract terms permitted, OxyChem fully implemented the $20 per ton
     price increase announced in the 3rd quarter.

o    OxyChem announced an additional $20 per ton increase to be effective
     December 1 to most accounts. Other U.S. chlor-alkali producers announced
     similar increases. Market conditions are expected to remain favorable for
     the successful implementation of the announced price increase.

o    1st quarter operating rates are expected to remain at capacity as the
     seasonal demand for downstream products improves.

o    Order control programs for chlorine are still in effect and are expected to
     remain so through the 1st quarter for OxyChem and other U.S. producers.


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

The normal seasonal decline in demand has made it easier to avoid customer
shutdowns. The availability of spot chlorine indicates a further balancing of
supply and


                                                                              13

demand. However, spot chlorine remains limited and pricing is at or above
current contract levels. Increased chlorine consumption into downstream
derivatives in the 1st quarter is expected to tighten the supply/demand balance.


CAUSTIC
- -------
OXYCHEM COMMENTARY
- ------------------

o    Caustic soda sales remained strong in the 4th quarter and consistent with
     3rd quarter volumes fueled by demand in the alumina, organic and refining
     markets. Sales into the bleach market did experience the customary seasonal
     decline.

o    OxyChem successfully implemented in the 4th quarter the $110 DST price
     increase announced in the 3rd quarter. An additional increase of $50 DST
     was announced November 1st. Market conditions are expected to remain
     favorable for the successful implementation of the announced price increase
     in the 1st quarter of 2005.

o    U.S. Gulf Coast producers settled the alumina pricing for the first half of
     2005 at $325 DMT FOB U.S. Gulf Coast. This represents a $211 DMT premium
     over the second half of 2004 and a $50 DMT premium over that of Asian
     producers' pricing for the first half of 2005.

o    Order control programs for liquid caustic soda remained in effect through
     the 4th quarter and are expected to continue into 2005.

INFLUENCING FACTORS:
- --------------------
The supply/demand balance projected for the 1st quarter is expected to lend
support for future price increases. Continuing improvement in the U.S.
manufacturing sector will keep liquid caustic soda demand in line with supply.


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

o    EDC pricing continued in an upward trend through mid-November when PVC
     pricing moderated in China.

o    Despite a balanced to tight supply/demand balance, EDC pricing moderated to
     mid-3rd quarter levels, maintaining the gap between EDC and PVC prices.

o    Scheduled VCM outages in December coupled with seasonally lower PVC demand
     in Asia reduced the need for EDC late in the 4th quarter.

INFLUENCING FACTORS:
- --------------------
The supply/demand balance for EDC in Asia is expected to tighten late in the 1st
quarter after the Chinese New Year period in February. Improved demand for EDC
and its downstream vinyl derivatives is also expected to result in increased EDC
pricing. Chlorine availability within the U.S. for EDC production will tighten
as seasonal demand for chlorine increases.

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

o    OxyChem's 4th quarter operating rate fell to 90% from a 3rd quarter average
     of 95% due to scheduled 4th quarter outages at three PVC plants.

o    A strong domestic and export market in the 4th quarter resulted in
     increased operating rates for PVC and minimal inventory build by producers
     as they tried to prepare for the seasonal spring surge in demand.

o    Strong PVC demand and low operating rates at Pemex kept the VCM
     supply/demand balance tight. PVC production was interrupted at one Latin
     American producer due to VCM availability.

o    Westlake has restarted the Geismar VCM and PVC plants at reduced rates. It
     is expected that the plants will be brought up to a 50% operating rate in
     2005. The Shintech Addis facility remains idle and is not expected to
     restart in 2005.

o    Domestic PVC resin prices were flat in October, increased $0.01 per pound
     in November and another $0.02 per pound in December.

o    PVC resin export prices weakened in December but closed the quarter at $870
     - $920 per metric ton CFR Southeast Asia. Normal seasonal decline in PVC
     demand was experienced in December.

o    Spot VCM export prices to Latin America closed the 4th quarter at $810 -
     $820 per metric ton FOB U.S. Gulf Coast. VCM shipments to Asia did not
     occur due to high freight rates in the range of $200 per metric ton.

o    Additional price increase for January has been announced for domestic PVC
     resin of $0.02 per pound.

INFLUENCING FACTORS:
- --------------------
Favorable domestic demand along with a seasonal rebound in the export market and
moderation of energy costs will result in improved margins for the first half of
2005.

Investor Relations Supplemental Schedules
[OXY LOGO]


Statements in this filing that contain words such as "will", "expect" or
"estimate", or otherwise relate to the future, are forward-looking and involve
risks and uncertainties that could significantly affect expected results.
Factors that could cause results to differ materially include, but are not
limited to: global commodity pricing fluctuations and supply/demand
considerations for oil, gas and chemicals; higher-than-expected costs; political
risk; and not successfully completing (or any material delay in) any expansion,
capital expenditure, acquisition, or disposition. Occidental disclaims any
obligation to update any forward-looking statements. The United States
Securities and Exchange Commission (SEC) permits oil and natural gas companies,
in their filings with the SEC, to disclose only proved reserves demonstrated by
actual production or conclusive formation tests to be economically producible
under existing economic and operating conditions. We use certain terms in this
presentation, such as probable, possible and recoverable reserves, that the
SEC's guidelines strictly prohibit us from using in filings with the SEC. U.S.
investors are urged to consider carefully the disclosure in our Form 10-K,
available through the following toll-free telephone number, 1-888-OXYPETE
(1-888-699-7383) or on the Internet at http://www.oxy.com. You also can obtain a
copy from the SEC by calling 1-800-SEC-0330.
