UNDERSTANDING EGYPT PRODUCTION SHARING CONTRACTS AND TAX BARRELS

FORWARD-LOOKING STATEMENTS Certain statements in this presentation contain "forward-looking statements" within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Securities and Exchange Act of 1934 including, without limitation, expectations, beliefs, plans and objectives regarding production and exploration activities. Any matters that are not historical facts are forward-looking and, accordingly, involve estimates, assumptions, risks and uncertainties, including, without limitation, risks, uncertainties and other factors discussed in our most recently filed Annual Report on Form 10-K, recent Quarterly Reports on Form 10-Q, recent filed Current Reports on Form 8-K available on our website, http://www.apachecorp.com/, and in our other public filings and press releases. These forward-looking statements are based on Apache Corporation s (Apache) current expectations, estimates and projections about the company, its industry, its management s beliefs and certain assumptions made by management. No assurance can be given that such expectations, estimates or projections will prove to have been correct. A number of factors could cause actual results to differ materially from the projections, anticipated results or other expectations expressed in this presentation, including, Apache s ability to meet its production targets, successfully manage its capital expenditures and to complete, test and produce the wells and prospects identified in this presentation; to successfully plan, secure necessary government approvals, finance, build and operate the necessary infrastructure and LNG plants; and to achieve its production and budget expectations on its projects. Whenever possible, these forward-looking statements are identified by words such as expects, believes, anticipates, projects, and similar phrases. Because such statements involve risks and uncertainties, Apache s actual results and performance may differ materially from the results expressed or implied by such forward-looking statements. Given these risks and uncertainties, you are cautioned not to place undue reliance on such forward-looking statements, which speak only as of the date hereof. Unless legally required, we assume no duty to update these statements as of any future date. However, you should review carefully reports and documents that Apache files periodically with the Securities and Exchange Commission. Cautionary Note to Investors: The United States Securities and Exchange Commission ("SEC") permits oil and gas companies, in their filings with the SEC, to disclose only proved, probable, and possible reserves that meet the SEC's definitions for such terms. Apache may use certain terms in this presentation, such as resource, resource potential, net resource potential, potential resource, resource base, identified resources, potential net recoverable, potential reserves, unbooked resources, economic resources, net resources and other similar terms that the SEC guidelines strictly prohibit Apache from including in filings with the SEC. Such terms do not take into account the certainty of resource recovery, which is contingent on exploration success, technical improvements in drilling access, commerciality and other factors, and are therefore not indicative of expected future resource recovery and should not be relied upon. Investors are urged to consider carefully the disclosure in Apache s Annual Report on Form 10-K for the fiscal year ended December 31, 2012, available from Apache at www.apachecorp.com or by writing Apache at: 2000 Post Oak Blvd., Suite 100, Houston, Texas 77056 (Attn: Corporate Secretary). You can also obtain this report from the SEC by calling 1-800-SEC-0330 or from the SEC's website at www.sec.gov. 2

ILLUSTRATIVE EXAMPLE TAX BARRELS HOW DO THEY WORK? How do income taxes work in Egypt? Apache and EGPC both incur A.R.E. federal income taxes Per the terms of the PSC, EGPC pays Apache s income taxes to the A.R.E on behalf of Apache The taxes paid by EGPC on behalf of Apache are treated as additional income to Apache for U.S. GAAP purposes Results in a gross-up calculation Apache files tax returns with A.R.E. and is issued a certificate from the Tax Authority stating EGPC paid taxes to A.R.E. on Apache s behalf Calculation of Income Tax Gross-Up Pre-tax Income ($MM) = $1,663 x (Effective Tax Rate / (1 Effective Tax Rate)) Tax Gross Up ($MM) = $1,475 13
