     Good morning. It's a pleasure to be here at Banc of America Securities'
2003 Energy & Power Conference.


                                                                               1

                                Performance Goals                     [OXY LOGO]


     o    Top Quartile Total Return to Shareholders

     o    Top Quartile Financial Performance
          -    Return on equity
          -    Return on capital employed

     o    Top Quartile Operational Performance
          -    Profits per BOE
          -    Free cash flow per BOE
          -    Finding & development cost per BOE


- --------------------------------------------------------------------------------


     When we began restructuring Occidental in 1997, our focus was on achieving
one primary objective - generating a total return to shareholders that ranked in
the top quartile among our large-cap oil and gas competitors.

     This required achieving top quartile financial performance as measured by
returns on equity and capital employed.

     We believed we could achieve top quartile financial returns by being a top
quartile performer in terms of profitability, free cash flow and finding and
development costs per BOE.

     This morning, I'm going to give you a progress report on how well we're
doing - beginning with the strategy that is driving our performance.


                                                                               2

                           Overall Business Strategy                  [OXY LOGO]


                OIL AND GAS

     o    Focus on large, "legacy" oil
          and gas assets in U.S.,
          Middle East and Latin
          America

                 CHEMICALS                                     [photo]

     o    Harvest cash

               BALANCE SHEET

     o    Maintain strong balance
          sheet


- --------------------------------------------------------------------------------


     Our business strategy is focused on large, long-lived, cost-competitive oil
and gas "legacy" assets in the U.S., the Middle East and Latin America. These
large core assets give us stable production, strong earnings and cash flow and a
solid platform for new growth initiatives.

     The role of our chemical business is to generate cash. Our core chemical
business has always generated positive cash flow - even under the most difficult
market conditions.

     The third element of our strategy is to maintain a strong balance sheet -
and we've succeeded in establishing the strongest balance sheet in more than two
decades. A strong balance sheet lowers our risk profile and provides the
financial flexibility needed to capture new opportunities for profitable growth
and to increase dividends.


                                                                               3

          -    Exploration
          -    Enhanced recovery
          -    Acquisitions


- --------------------------------------------------------------------------------


Our overall business strategy is driven by our oil and gas business model which
has three components. Each of these components plays an important role:

     o    We focus on adding commercial reserves in and around our core areas
          through the drill bit.

     o    We pursue opportunities with host governments in our core areas to
          enhance the development of mature fields with large volumes of
          remaining oil in place.

     o    Finally, we maintain a disciplined approach in buying assets whose
          performance can be improved by the application of new technology and
          practices.

     o    This business model is both flexible and durable.

     As I noted earlier, one of our objectives when we began restructuring in
1997 was to become a top quartile performer in returns on equity and capital
employed.

     This slide shows where we ranked in return on equity compared with 12 other
large-cap oil and gas companies - based on rolling three-year average returns.

     As you can see, we ranked 12th in 1997 based on the three-year average
returns for 1995 through 1997.

     By 2002, we moved up to number one based on our performance during the 2000
- - 2002 period.

     Our free cash flow per barrel, which is net of capital expenditures, shows
a correlation with our profitability. From 2000 through 2002, Occidental's
average annual free cash flow per barrel of $9.37 led the industry - and was 55
percent higher than the company next in line and 125 percent higher than the
industry average of $4.19 per barrel.

average over the last three years was $4.09.

     We expect our 2003 F&D costs to be well below $5.00 per BOE.

     Replacement rates and finding costs can vary significantly from
year-to-year. That's why it's important to measure performance over a multi-year
period to determine a company's real underlying strengths. As you can see,
Occidental had the lowest average F&D costs for the 2000 through 2002 period.

     While we are succeeding in keeping our costs down, we're also dramatically
increasing our reserves.

     Since 1999, our proven oil and gas reserves have grown by over 70 percent.
Our year-end 2002 proven reserves exceeded 2.3 billion BOE - the highest level
in our history.

     Domestic reserves, shown in green, accounted for 76 percent of our
worldwide reserves at the end of last year - compared to 57 percent at the end
of 1999. This shift lowers our risk profile and provides a large, stable
domestic base to support future growth opportunities.

          production forecast


- --------------------------------------------------------------------------------


     Let's look at three examples of how we are growing our production,
beginning with targeted acquisitions in our core areas.

     Last April we acquired 73 million barrels of proven reserves in the Permian
Basin for an average price of $3.20 per BOE.

     The acquisitions enhance our industry leading position in the Permian
Basin. We are the largest oil producer in Texas.

     Following these acquisitions, we raised our production forecast by 10,000
BOE per day for 2003 through 2006.


                                                                              17

     Oxy Net Production 2004 Forecast                    45,000 Barrels/Day


- --------------------------------------------------------------------------------


     We also have been growing through the drill bit in Ecuador where our
average net production through the first three quarters this year has increased
to 20,000 barrels of oil per day compared to 13,000 barrels per day in 2002.

     The new Eden-Yuturi oil field came on stream on September 1 with the start
up of the new trans-Ecuadorian pipeline known by its Spanish acronym OCP. We
expect net production for the full year to average 25,000 barrels per day.

     With the full annual benefit of production from Eden-Yuturi and other
recent discoveries in Block 15, we expect to increase our average net production
in Ecuador to 45,000 barrels per day in 2004 - and to maintain production at
that level through 2006.


                                                                              18

     Oxy's Net Production Estimate...........................30,000 BOE/Day


- --------------------------------------------------------------------------------


     The third example shows production growth being driven by large development
projects - like the Dolphin Project in the Middle East. This project involves
the development and transportation of approximately 2 billion cubic feet of gas
per day through a new trans-border pipeline from Qatar's giant North Field to
power and water desalination markets in the United Arab Emirates.

     We have a 24.5 percent stake in the project which will result in the
addition of an estimated 900 million cubic feet of gas equivalent net to
Occidental to our proven reserve base - which is equal to 150 million barrels of
oil. When fully operational, it will add estimated daily production of 125
million cubic feet of gas and 9,000 barrels of liquids net to Oxy - equal to
approximately 30,000 BOE per day.

     Gas supply agreements with the UAE were signed several weeks ago and the
project is moving forward toward its scheduled 2006 start up.

     Our success in growing production through acquisition, the drill bit and
development projects is reflected in our rising production profile.

day above our forecast.

     Our initial forecast for this year was 525,000 BOE per day. As I noted
earlier, we raised our forecast by 10,000 BOE per day in April following the
Permian acquisitions.

     I'm very pleased to report that our actual production through nine months
averaged 541,000 BOE per day, clearly placing us on track to surpass our
ambitious forecast of 535,000 BOE per day for the year.

and Qatar through EOR and REDEVELOPMENT work programs.

     We are moving ahead with a new natural gas project in Oman to produce
stranded gas. We expect start up in mid-2004.

     And, we are continuing to evaluate niche ACQUISITION opportunities in and
around our core areas - including new consolidation opportunities in the
Permian.

     Now, I'd like to shift your attention briefly to our chemicals business.
The role of our chemicals business in our corporate strategy is quite simple. It
is to generate free cash flow.

     And we've been accomplishing our objective in that regard. Since 1993, our
current mix of chemical businesses has produced average annual free cash flow of
$260 million.

     One of the effects of reducing debt has been the reduction in total
interest expense. We are estimating 2003 pre-tax interest expense to be
approximately $275 million - or $269 million less than in 2000. The savings
equates to an annual net improvement of 45-cents per share, and we expect
additional debt reduction next year.

     At the end of the third quarter, we had $529 million in cash on our balance
sheet.

     We plan to use some of these cash proceeds to redeem $454 million in 8.16
percent Trust Preferred Securities in January 2004. This redemption will result
in annual pre-tax savings of $39 million, for an annual net improvement of
6-cents per share.

     Let me say a few words about two significant investments we have outside
our core oil and gas and chemical businesses.

     We hold a 22 percent interest in Lyondell Chemical Company. On November 11,
our 39 million Lyondell shares had a market value of $575 million.

     We also have a 12 percent stake in the Premcor refining business. As of
November 11, our 9 million Premcor shares had a market value of $210 million.

     The total implied value for these investments is $2.00 per share.

     We believe both investments have substantial upside.


                                                                              27

     As we have seen, our success in producing top quartile returns in
profitability, free cash flow and F&D costs per BOE has generated strong returns
on equity and capital employed.

     These results have, in turn, resulted in a top quartile total return to our
shareholders over the last five years when ranked against our large-cap oil and
gas competitors.

     While there is considerable variation in total returns within this group of
companies from week to week, Occidental has consistently been in the top
quartile throughout the year.

     As you have seen, we have clearly accomplished what we set out to do when
we began restructuring in 1997.

     The issue of corporate governance has been very much on the collective
minds of investors ever since the Enron collapse. Occidental began strengthening
its corporate governance policies in the early 1990s. Our policies are outlined
in our 2002 Annual Report to Stockholders and in the Comparative Performance
booklet that is part of the material distributed to you this morning.

     Occidental was one of fifteen U.S. and two Canadian firms to receive a top
corporate governance score of 10.0 by GovernanceMetrics International. GMI is an
independent governance agency that rated 1,000 U.S. and 600 foreign companies.

     A study by Institutional Shareholders Services, the world's leading
provider of proxy voting and corporate governance services, ranked Occidental's
corporate governance practices in the top 5 percent of the S & P 500 Index
companies.

          -    #1 in return on equity
          -    Top quartile returns on capital employed
          -    Top quartile replacement costs
          -    Competitive dividend

     o    Business strategy successful
          -    Profitable growth
          -    Disciplined investment decisions

     o    Top quartile total returns to shareholders


- --------------------------------------------------------------------------------


In summary, our financial performance over the past three years has been driven
by disciplined growth.

     o    Oil and gas production has been growing at an average annual rate of 5
          percent.

     o    For the years 2000 through 2002, our performance has excelled when
          compared to the other large-cap energy companies.

          o    We led our peers in profitability and free cash flow per BOE.

          o    Our return on equity was best in class.

          o    Our return on capital employed and our replacement costs were at
               the upper end of the top quartile.

          o    We pay a competitive dividend.

     o    Our business strategy is working. We are achieving profitable growth
          by making disciplined investment decisions.

     o    The end result has been top quartile total returns to shareholders
          whether you are looking at the last five years, the last three years
          or the results so far this year. I believe we will remain a top
          quartile performer for the foreseeable future.

o    Return on capital employed (ROCE) is calculated by dividing earnings
applicable to common shares, before interest expense, by average capital
employed (average debt plus equity); interest is added back after-tax (using a
35% statutory rate, not the effective rate).

o    Occidental management considers ROCE a useful measure because it indicates
the return on all capital, both debt and equity, employed in the business.
Occidental management believes that ROCE is an additional measure of efficiency
when used in conjunction with Return on Equity, which measures the return on
only the shareholders' equity portion of the total capital employed.

o    There is no GAAP free cash flow measure comparable to this calculation;
operating cash flow, investing cash flow, financing cash flow, and change in
cash calculated in accordance with GAAP are presented above for reference.

o    Oxy calculates free cash flow per barrel of oil equivalent (BOE) by taking
the exploration and production income after taxes but before interest, adding
back the depreciation, depletion & amortization and exploration expense, and
subtracting from that amount, total capital expenditures excluding acquisitions.
The result is then divided by the BOE sale volumes.

o    Occidental management believes that free cash flow per BOE is a useful
measure to show the net cash results of the Oil and Gas operation on a per
barrel basis. This measure is useful to compare the performance among companies
of varying sizes.

o    There is no GAAP free cash flow measure comparable to this calculation;
operating cash flow, investing cash flow, financing cash flow, and change in
cash calculated in accordance with GAAP are presented above for reference.

o    Oxy calculates free cash flow by taking Chemical segment income, excluding
the Petrochemical business results, after state taxes but before interest,
adding back the depreciation, depletion & amortization, and subtracting from
that amount, total capital expenditures excluding acquisitions.

o    Occidental management believes that free cash flow is a useful measure to
show net cash results of the Chemical operations.
