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; political events; 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 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 resource potential, net risked reserves, de-risked,
geologically viable, EUR (expected ultimate recovery), discovery volumes, likely recoverable resources and oil in place, that the
SEC’s guidelines strictly prohibit us from using in our SEC filings. These terms represent our internal estimates of volumes of
oil and gas that are not proved reserves but are potentially recoverable through exploratory driling or additional drilling or
recovery techniques and are not intended to correspond to probable or possible reserves as defined by SEC regulations. By
their nature these estimates are more speculative than proved, probable or possible reserves and subject to greater risk they will
not be realized. 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
