                              2004 ANNUAL MEETING



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


     2003 was an outstanding year for Occidental in delivering superior total
returns to our stockholders. Actually, we have been generating highly
competitive total returns over a number of years.

     This morning I'm going to review our past performance, as well as our
vision for the future. When a company achieves the kind of results we have, your
management and investors want to know how we will be able to sustain that level
of performance in the future.


                                                                               1

     I'm confident we can because we have a durable business model that will
continue to generate profitable growth projects. Our business model is driven by
three engines to add commercial oil and gas reserves and generate profitable
production growth - exploration, enhanced oil recovery projects and
acquisitions.

     Sustainable, profitable growth is essential to building long-term value for
stockholders. Our business model is supported by the tools we believe are
necessary to build and sustain profitable growth. These tools include a focused
business strategy, a long-lived asset base, a disciplined investment philosophy,
a strong balance sheet, a talented work force and a commitment to the principles
of responsible corporate citizenship.

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


     We use a number of financial criteria to measure our overall performance
versus our strategy and objectives - relative to our competition.

     Return on capital employed is especially important because it measures the
efficient use of capital, which is critical to building long-term value.

     Return on equity is a measure of the profitability of a business as a
percentage of stockholders' equity.

     However, in the final analysis, the most significant measure is the total
return to stockholders, which includes stock price change plus dividends.

     Let's look first at return on capital employed.


                                                                               4

     No company can be successful in building long-term value if does not get
good returns on its invested capital.

     For the period 2001 through 2003, our return of 12.6 percent was in the top
quartile performance, and is 30 percent higher than the industry average of 8.8
percent. Our goal is to be in the top quartile in our industry.

     Good returns on equity are synonymous with high profitability and strong
asset management.

     We're pleased that our three-year average return on equity of 18.5 percent
for the period 2001 through 2003 also was in the top quartile. The average for
our competitors was 11.9 percent.

     Since investors have many choices, it's instructive to see how our total
return to stockholders compares to the broader market. This chart shows that
Occidental's total return to stockholders in 2003 was a robust 53 percent, while
the Dow Jones Industrial Average generated a total return of 28 percent.

     During the three years from 2001 through 2003 our average annual return was
31 percent compared to the Dow's one percent.

     Over the five years from 1999 through 2003, our average annual total return
was 41 percent compared to negative one percent for the Dow.

     Let's now look at how our total returns compared to our large
capitalization oil and gas industry competitors.

     As I noted earlier, one of our objectives was to be a top quartile total
return performer in the oil and gas industry. As you can see, we clearly
achieved that objective last year. During 2003, robust energy prices contributed
to good returns for most of the peers shown here. However, we did exceptionally
well.

     Before addressing the underlying reasons for our strong comparative
performance, let's look at how our total returns compared to our industry
competitors over the last three years, as well as the last five years.

     Our total return of 93 percent from 2001 through 2003 was nearly three
times higher than our nearest competitor. Once again, these returns are based on
the assumption that all dividends were reinvested and the stock was held for the
entire three-year period.

     Over the last five years, our 205-percent return was clearly in the upper
quartile and significantly exceeded the returns of most of our competitors.

     These overall results are linked to our success in executing our strategy
at the operational level in our oil and gas and chemicals businesses.


                                                                              10

     Our overall strategy to continue building long-term value is focused on our
core oil and gas areas in the United States, the Middle East and Latin America.

     Our ability to generate a rising stream of free cash flow is especially
critical to our ability to invest in new projects, reduce debt and support
dividend growth. By free cash flow, I mean cash flow from our operations less
capital expenditures. Our primary sources of free cash flow are our domestic oil
and gas and chemical businesses.

     We are committed to maintaining a strong balance sheet to reduce the risk
for investors and provide the company with the financial strength and
flexibility to compete for new business.

     We will continue to review our dividend policy annually as part of our
commitment to build long-term value for our stockholders.

     As we succeed in increasing production each year, the challenge of
replacing the reserves we produce becomes increasingly demanding. Our team has

approximately 140 percent of our production. Last year we did even better with a
replacement rate of 184 percent.

     These replacement rates increased our proved oil and gas reserves to new
historical highs in each of the last three years.

     Domestic reserves, shown in green, accounted for more than 70 percent of
our worldwide total during this period. The predominance of a large, low-risk
domestic base provides a solid portfolio to generate the free cash flow needed
to support future growth opportunities.

     As you can see, Occidental's average replacement costs for 2001 through
2003 put us in the top quartile. We are in excellent shape as we look to the
future since our costs are $2.80 per BOE below the average costs of our
competition. Keeping our finding and development costs low is one of the keys to
maintaining a competitive edge in terms of future profitability.

     Our free cash flow per barrel, which is net of capital expenditures, shows
a high correlation with our profitability. From 2001 through 2003, Occidental's
free cash flow per barrel of $8.83 led the industry - and was more than double
the industry average of $3.95 per barrel.

     Our ability to produce top quartile free cash flow gives us the flexibility
and financial leverage to compete successfully for new high potential investment
opportunities to build long-term value.

     Over the past 10 years, our chemical business has provided free cash flow
to invest in our oil and gas business, reduce debt or pay dividends. We have
restructured our chemical business to improve the overall efficiency of the
operations. We expect this business to generate annual free cash flow in excess
of $300 million in 2004 and beyond.

     Since 2000, we have improved our financial leverage by lowering our
debt-to-capitalization ratio from 57 percent to 33 percent. We have no
significant debt maturities in the remainder of 2004.

     Our success in strengthening our balance sheet resulted in all three credit
agencies upgrading our credit ratings in 2003. Moody's upgraded us to B Double A
One, while S&P and Fitch raised our rating to "Triple B+".

     One of the effects of paying down debt is lower interest expense. Annual
interest expense declined from $546 million in 2000 to $272 million last year.

     That's a total savings of $274 million compared to 2000 and equates to an
annual net improvement of 46 cents per share.

     The improvement in our balance sheet, combined with the outlook for future
earnings and free cash flow growth, were key drivers in the decision taken by
the Board of Directors to increase our dividend payouts in 2003 and 2004.

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


     Our past success has raised expectations for the future. The primary
interest of investors today is whether we can sustain this pattern of profitable
growth in future years.

     The simple answer to that question is, "yes". Our strong past performance
has laid a solid foundation for building long-term value.

     We are continuing to execute our strategy of creating value through a
combination of exploration, enhanced oil recovery projects and acquisitions in
our core oil and gas business, while maximizing free cash flow from chemicals.

     Let's focus now on our forecast through 2006.

     As you can see, we expect the U.S. to remain the dominant region in our
production profile and account for 55 percent of our worldwide production in
2006.

     We expect the Middle East to be our primary growth area and to contribute
26 percent of our 2006 production.

     We expect our 2006 Latin American production to make up 11 percent of the
total.

     The "Other" category is made up of Russia and Pakistan.

     Maintaining a strong U.S. base is a critical element in supporting our
growth plans.


                                                                              23

     In Ecuador, our production is growing as a result of exploration success.

     Our 2003 average net production of 25,000 barrels of oil per day was nearly
double our 2002 rate. The increase is the result of the commissioning last
September of the new OCP pipeline.

     We expect the impact of a full year of production from the new Eden-Yuturi
field and another smaller discovery to increase our total Ecuador production to
an average of 45,000 barrels per day in 2004 - and we expect to remain at that
level at least through 2006.

     We believe our Block 15 has additional exploration potential and we are
evaluating EOR opportunities outside our block that can have a material effect
on future production growth.

     In Oman, we have a new natural gas project that came on stream this year.
The project is supplying gas associated with oil production from our Block 9
operations through a new pipeline and processing facilities to the Fujairah
power plant in the United Arab Emirates.

     Occidental's sale agreement calls for the delivery of 120 million gross
cubic feet per day. Occidental's share is 78 million cubic feet per day.

     The installed facilities are capable of handling 150 million cubic feet per
day. In the second half of this year, Occidental expects to make available
additional sales volumes up to the maximum capacity.


                                                                              27

     With a contract that runs through 2019, Qatar represents another long-lived
asset in the Middle East

     This successful EOR project began in October 1994. Before Occidental took
over the operation, gross production had fallen from a peak of 50,000 barrels
per day to approximately 20,000 barrels per day.

     Thanks to our efforts, gross production during 2003 averaged approximately
95,000 barrels, with Oxy's net share at 45,000 barrels per day. We are now
implementing a second phase of development investment focused on the large ISND
Field to further increase production.

     Occidental's share of the $4 billion capital for this project is
approximately $1 billion over the next three years. We expect to finance a
portion of the project.

     When this project is fully operational in late 2006, we expect Occidental's
net production to be about 275 million cubic feet of gas per day and 20,000
barrels of liquids per day. Over the 25-year life of the project, we expect our
cumulative production to be approximately 1.3 trillion cubic feet of gas and 85
million barrels of liquids.

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


     Last week's announcement by the Bush Administration that it was lifting the
remaining economic sanctions on Libya removes the final obstacle to Occidental's
return to Libya after an absence of nearly 18 years.

     Occidental and other U.S. companies, who had commercial interests in Libya,
were required to leave the country in 1986 when the Reagan Administration
imposed economic sanctions on the Libyan Government.

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


     Libya played an important role in Occidental's evolution from a small
California oil company into a significant player in the global oil business. In
1966, Occidental made its first of several giant discoveries that together
totaled nearly 3 billion gross barrels.

     Production began flowing to our export terminal in 1968, the same year that
a group of army officers led by Colonel Ghadafi deposed King Idris.

     The following year gross production rose to a peak of nearly 660,000
barrels of oil per day.

     By 1974, while OPEC's influence was on the rise, Libya completed the
nationalization of 51 percent of all foreign oil interests - including
Occidental's operations.

     Increasingly strained U.S. - Libyan relations during the Carter
Administration culminated with the implementation of broad economic sanctions
against Libya by President Reagan. In 1986, Occidental was ordered to leave
Libya in compliance with the sanctions.


                                                                              33

                                               US Lifts Remaining Sanctions


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


     In 1999, the Clinton Administration permitted Oxy technical teams to visit
Libya for the purpose of assessing the condition of our existing assets. Since
that time, our team has made several visits to Libya.

     Real improvement in U.S. - Libyan relations did not begin until December
2003 when the Libyan Government agreed to abandon its pursuit of weapons of mass
destruction and to cooperate in the war on terror.

     In early March of this year, the Bush Administration reestablished a
diplomatic presence in Tripoli, lifted the ban on travel to Libya by U.S.
citizens and authorized U.S. oil companies, with assets in Libya when sanctions
were implemented, to negotiate and sign contracts for their return to the
country.

     From March 13th through the 15th, I visited Libya with three of my Oxy
colleagues for high level visits with the Libyan leadership, including Colonel
Ghadafi. We were impressed by their enthusiasm in welcoming our return.

     The lifting of U.S. sanctions last week will allow Occidental to resume
commercial activities in Libya.

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


     During our visit, we presented Libyan authorities with our investment and
technical proposals that we believe can bring significant benefits to the Libyan
people and to our stockholders by significantly increasing Libya's reserves and
production.

     We regard our return to Libya as one of our high priority projects. We look
forward to continued progress in U.S. - Libyan relations and in our negotiations
to update our existing exploration and production agreements. Our technical
teams are already hard at work, and we plan to open an office in Tripoli as soon
as possible. I am planning to return to Libya in the near future to help
facilitate negotiations.

     As our business development teams focus on new opportunities for building
profitable long-term growth, our operations teams are producing strong near-
term results. The momentum we developed last year has carried over into the
first quarter, resulting in a very strong first quarter this year.

     Our consolidated quarterly net income was $487 million, or $1.24 per share.
Cash from operations was approximately $965 million. Stockholders' equity
increased to a record $8.5 billion.

     A key element in building long-term value for stockholders is the payment
of dividends. Occidental has been paying cash dividends without interruption
since 1975.

     The Board of Directors increased the dividend by 6 percent this February.
This is on top of last year's increase of 4 percent.

     The Board will continue to review dividend policy annually as part of our
continuing commitment to increase total returns for our shareholders.

[OXY LOGO]     WHAT'S AHEAD?

                     to Support Growth
                  -  Continue Adding Highly Profitable New Projects

               o  Stay Focused on the Fundamentals
                  -  Maintaining Discipline and Focus
                  -  Executing Our Strategy
                  -  Balancing Growth With Profitability

               o  Create Long-Term Value


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


     The company's future success depends on two factors. First, we must
continue to take care of our asset base in order to generate the cash to support
our strategy of building long-term growth. Second, we must continue to add
profitable new projects to our portfolio, like Dolphin. We believe the interests
of our stockholders are best served by remaining focused on these fundamentals.

     Our strength has been our financial discipline and focus in executing our
strategy that balances long-term growth with near term profitability. The
investments we are making now in projects will yield profitable growth
opportunities and stockholder value for many years.

     I would like to pay special tribute to our employees who take the execution
of our strategy personally and who have demonstrated a passion for our company's
success. I am also thankful for the foresight and guidance of our directors who
are committed to creating long-term value for our stockholders. Finally, I would
like to express my appreciation to our loyal stockholders who supported us
through a difficult transition.

     Ladies and gentlemen - let me assure you, the best is yet to come.

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

Occidental management believes that Free Cash Flow per BOE is a useful
operational statistic to show the net cash results of the oil and gas operation
on a per barrel basis. This measure is useful to compare different-sized
companies.

Statements in this presentation that contain words such as "will" or "expect",
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; 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
