Portions of this presentation contain forward-looking statements and involve risks and uncertainties that could
materially affect expected results of operations, liquidity, cash flows and business prospects. Factors that could
cause results to differ materially include, but are not limited to: global commodity pricing fluctuations; supply and
demand considerations for Occidental’s products; not successfully completing, or any material delay of, any
development of new fields, expansion projects, capital expenditures, efficiency-improvement projects, acquisitions or
dispositions; potential failure to achieve expected production from existing and future oil and gas development
projects; exploration risks such as drilling unsuccessful wells; any general economic recession or slowdown
domestically or internationally; higher-than-expected costs; potential liability for remedial actions under existing or
future environmental regulations and litigation; potential liability resulting from pending or future litigation; general
domestic and international political conditions; potential disruption or interruption of Occidental’s production or
manufacturing or damage to facilities due to accidents, chemical releases, labor unrest, weather, natural disasters,
political events or insurgent activity; failure of risk management; changes in law or regulations; or changes in tax
rates. Finding and Development costs calculations inherently compare costs and reserves from separate periods.
The United States Securities and Exchange Commission (SEC) permits oil and natural gas companies, in their SEC
filings, to disclose only reserves anticipated to be economically producible, as of a given date, by application of
development projects to known accumulations. We use certain terms in this presentation, such as reported reserves,
EUR, expected ultimate recovery, potential reserves, discovery volumes, recoverable resources and oil in place, that
the SEC’s guidelines strictly prohibit us from using in our SEC filings. You should not place undue reliance on these
forward-looking statements, which speak only as of the date of this presentation. Unless legally required, Occidental
does not undertake any obligation to update any forward-looking statements, as a result of new information, future
events or otherwise. U.S. investors are urged to consider carefully the disclosures in our 2009 Form 10-K, available
through the following toll-free number 1-888-OXYPETE (1-888-699-7383) or on the internet at http://www.oxy.com.
You also can obtain a copy form the SEC by calling 1-800-SEC-0330. We post or provide links to important
information on our website including investor and analyst presentations, certain board committee charters and
information that SEC requires companies and certain of its officers and directors to file or furnish. Such information
