Subject Company: Anadarko Petroleum Corporation
Commission File No.: 001-08968


The following letter was sent by email to all employees of Occidental Petroleum Corporation on April 24, 2019.

Dear Colleagues,

Today we announced that we are making an offer for Anadarko that would create a more than $100 billion global energy leader, and I want to take a moment to share what that means.

Thanks to the continued execution of our strategic vision and your hard work, we are in the strongest position of our 99-year history. As we approach our 100-year anniversary at Occidental in 2020, we are presented with a unique opportunity to enhance our shareholder value proposition by improving returns through a portfolio with greater scale and synergies.

We believe that a transaction with Anadarko would drive meaningful value for Occidental and our shareholders, and we are confident that we could take Anadarko’s assets and apply our technology and demonstrated operating strength to create something greater.

Of course, there is no guarantee that we will complete this transaction. Regardless of the outcome, I remain confident that we are well positioned for the future and will continue to empower all of you to execute our strategic vision.

At this time, we will continue to operate business-as-usual with a continued focus on safe operations. It is important to note that the increased attention on our company will likely continue over the coming days, and as a reminder, if you are contacted by the media, please direct them to Melissa Schoeb.

Thank you for your continued focus and dedication.

Sincerely,

Vicki Hollub
President and Chief Executive Officer




Forward Looking Statements

Any statements in this communication about Occidental’s expectations, beliefs, plans or forecasts, including statements regarding the proposed transaction between Occidental and Anadarko, benefits and synergies of the proposed transaction and future opportunities for the combined company and products and securities, that are not historical facts are forward-looking statements. These statements are typically identified by words such as “estimate,” “project,” “predict,” “will,” “would,” “should,” “could,” “may,” “might,” “anticipate,” “plan,” “intend,” “believe,” “expect,” “aim,” “goal,” “target,” “objective,” “likely” or similar expressions that convey the prospective nature of events or outcomes. Forward-looking statements involve estimates, expectations, projections, goals, forecasts, assumptions, risks and uncertainties. Actual results may differ from anticipated results, sometimes materially, and reported or expected results should not be considered an indication of future performance. Factors that could cause actual results to differ include, but are not limited to: the ultimate outcome of any possible transaction between Occidental and Anadarko, including the possibility that Anadarko will reject the proposed transaction with Occidental or that the terms of any definitive agreement will be materially different from those described above; uncertainties as to whether Anadarko will cooperate with Occidental regarding the proposed transaction; the parties’ ability to consummate the proposed transaction; the conditions to the completion of the proposed transaction, including the receipt of Anadarko stockholder approval and receipt of Occidental stockholder approval; that the regulatory approvals required for the proposed transaction may not be obtained on the terms expected or on the anticipated schedule or at all; Occidental’s ability to finance the proposed transaction; Occidental’s indebtedness, including the substantial indebtedness Occidental expects to incur in connection with the proposed transaction and the need to generate sufficient cash flows to service and repay such debt; Occidental’s ability to meet expectations regarding the timing, completion and accounting and tax treatments of the proposed transaction; the possibility that Occidental may be unable to achieve expected synergies and operating efficiencies within the expected time-frames or at all and to successfully integrate Anadarko’s operations with those of Occidental; that such integration may be more difficult, time-consuming or costly than expected; that operating costs, customer loss and business disruption (including, without limitation, difficulties in maintaining relationships with employees, customers or suppliers) may be greater than expected following the proposed transaction or the public announcement of the proposed transaction; the retention of certain key employees of Anadarko may be difficult; that Anadarko and Occidental are subject to intense competition and increased competition is expected in the future; general economic conditions that are less favorable than expected. Additional risks that may affect Occidental’s results of operations and financial position appear in Part I, Item 1A “Risk Factors” of Occidental’s Annual Report on Form 10-K for the year ended December 31, 2018, and in Occidental’s other filings with the U.S. Securities and Exchange Commission (“SEC”).

Because the factors referred to above could cause actual results or outcomes to differ materially from those expressed or implied in any forward-looking statements, you should not place undue reliance on any such forward-looking statements. Further, any forward-looking statement speaks only as of the date of this communication and, unless legally required, Occidental does not undertake any obligation to update any forward-looking statement, as a result of new information, future events or otherwise.
