Exhibit 10.1

APACHE CORPORATION

2014 EMPLOYEE RELEASE AND SETTLEMENT AGREEMENT

The parties to this agreement are APACHE CORPORATION (“Apache”) and Thomas P. Chambers (“Employee”).

This document describes the agreements of Apache and Employee concerning the termination of Employee’s employment with Apache. This agreement and the severance pay and other benefits described below give valuable consideration to both Apache and Employee.

Termination of Employment Relationship: Apache and Employee have agreed that Employee’s employment relationship with Apache will terminate on August 31, 2014 (the “Termination Date”). Apache and Employee both agree that Employee will “separate from service” (for purposes of section 409A of the Internal Revenue Code of 1986, as amended (the “Code”)) on August 31, 2014.

Termination Pay: Apache will pay Employee the following as soon as reasonably practical following the Termination Date:

Such amounts shall be subject to all lawful deductions.

Severance Pay: Subject to this agreement becoming effective, Apache will pay Employee a lump sum amount of $1,600,000 of Severance Pay.

The Severance Pay has been subject to arms’ length negotiations between the parties and thus is not deferred compensation subject to Code section 409A. The Severance Pay will be subject to all lawful deductions and withholding for taxes and will be paid as soon as administratively practical after this agreement becomes effective. Additional FICA taxes will also be withheld from this payment for any additional severance benefits discussed below that become subject to FICA taxation when this Agreement becomes effective, even though many of the additional severance benefits will not be paid or subject to federal income tax until later years.

Additional Severance Benefits: Subject to this agreement becoming effective and subject to any delay in payment required by Code section 409A, Apache will provide Employee with the following additional Severance Benefits:

Employee Acknowledgement: Employee acknowledges that the Severance Pay and Severance Benefits are consideration over and above that to which Employee otherwise would be entitled upon termination of employment, and are paid in consideration for this agreement.

Employee Resignation: Employee agrees to resign from all positions he holds with Apache and its affiliates forthwith and to sign all documents necessary to effectuate his resignations.

Release by Employee: In consideration of receipt of the Severance Pay and Severance Benefits, Employee hereby releases and waives, on behalf of himself, his heirs, estate, beneficiaries and assigns, all claims of any kind or character for loss, damage or injury arising from, based upon, connected in any way with, or relating to the following (“Claims”):

Claims Included: The Claims released and waived by Employee are those arising before the effective date of this agreement, whether known, suspected, unknown or unsuspected, and include, without limitation:

Claims Excluded: Employee does not release or waive (1) any rights that may not by law be waived, (2) vested benefits, if any, to which Employee may be entitled pursuant to the terms of Apache’s benefits plans, including Employee’s right to any benefits under health, life or disability policies covering Employee and Employee’s right to all vested incentive compensation and the continued vesting thereof as described in this Agreement (for the avoidance of doubt,

Employee is, however, releasing and waiving any claim that he is subject to or covered by any Change of Control provisions other than the continuation of vesting of Apache Corporation equity), or (3) the right to recovery for breach of this agreement by Apache,(4) Employee’s right to indemnity, contribution and a defense under any agreement, statute, by-law or company agreement or other corporate governance document, (5) Employee’s right to continuing coverage under all Apache directors’ and officers’, fiduciary, errors and omissions and general liability and umbrella insurance policies, (6) payment to Employee of any unpaid business or business travel expense payable under the Company’s usual practices, (7) distribution to Employee, as soon as practical after the effective date of this agreement and consistent with the requirements of Code section 409A, applicable deferral agreements and governing terms of any Plan, previously vested but withheld shares of restricted stock, (8) Employee’s rights as an option holder, as a holder of restricted stock and as a shareholder; (9) any deferred compensation including Employee’s right to any payment or compensation that may be deferred because of compliance with Code section 409A; (10) Employee’s rights to payment of overrides under previous Apache employee benefit plans and (11) Employee’s rights as a retiree of Apache.

Agreement Not To Sue: Employee will not sue any Released Party for any released Claim. Excluded from this agreement not to sue is Employee’s right to file a charge with an administrative agency or participate in an agency investigation. Employee is, however, waiving the right to receive money in connection with such charge or investigation. Employee is also waiving the right to recover money in connection with a charge filed by any other individual or by the Equal Employment Opportunity Commission or any other federal or state agency.

Future Employment: The Released Parties will not have any obligation to consider or accept any future employment or reinstatement application from Employee.

No Admission: Neither Apache nor Employee alleges or admits any wrongdoing or liability. Apache and Employee have executed this agreement solely to avoid the expense of potential litigation. The additional Severance Pay and additional Severance Benefits described above fully compromise and settle any and all Claims of Employee.

Confidentiality: Employee and Apache will keep this agreement strictly confidential, except that Employee may disclose this agreement to his spouse, attorneys, financial and tax advisors and will cause Employee’s spouse, attorneys, financial and tax advisors to do likewise, and Apache may disclose this agreement to its officials who need to see this agreement and shall cause them to keep this agreement strictly confidential, except, as to both parties, to the extent disclosure is necessary for tax, securities law and regulations, stock exchange rules, financial advice, tax advice and filings or other legal requirements.

Confidences: Employee will maintain the confidentiality of all Released Party trade secrets, proprietary information, insider information, security procedures and other confidences that came into Employee’s possession or knowledge during employment by Apache. Employee will not use information concerning a Released Party’s business prospects or practices to profit Employee or others. The parties understand Employee may elect to continue his professional activities and/or employment in the oil and gas exploration and development industry subsequent

to the Termination Date. Accordingly, nothing in this agreement shall prevent Employee from utilizing general knowledge, skills and experience he acquired during his employment with Apache. Further, nothing in this agreement shall prevent Employee from using any public information that is generally known or reasonably accessible or available to him

Property: Employee represents that Employee possesses no property of a Released Party. If any Released Party property comes into Employee’s possession before departure from Apache premises, or if the date of Employee’s termination is in the future, Employee will return the Released Party property to Apache prior to departure from the Apache premises and without request or demand by Apache.

References: Apache may respond to inquiries from third parties about Employee’s employment with Apache by identifying only Employee’s date of hire, date of termination and position held at the time of termination of employment. Apache will have no obligation to provide further information to prospective employers of Employee.

Non-disparagement: Employee shall refrain from publishing any oral or written statements about the Company, any Apache Entity and/or any of the Released Parties that are disparaging, slanderous, libelous, or defamatory; or that disclose private or confidential information about their business affairs; or that constitute an intrusion into their seclusion or private lives; or that give rise to unreasonable publicity about their private lives; or that place them in a false light before the public; or that constitute a misappropriation of their name or likeness. Likewise, the Released Parties shall refrain from publishing any oral or written statements about Employee that are disparaging, slanderous, libelous, or defamatory; or that disclose private or confidential information about his business affairs; or that constitute an intrusion into seclusion or private life; or that give rise to unreasonable publicity about his private life; or that places him in a false light before the public; or that constitute a misappropriation of his name or likeness.

Assistance in Legal Actions: In the event Apache is or becomes involved in any legal action relating to events which occurred while Employee was rendering services to Apache or about which Employee possesses any information, Employee agrees to assist, subject to Employee’s “reasonable availability”, in the preparation, prosecution or defense of any case involving Apache, including without limitation, executing truthful declarations or documents or providing information requested by Apache and attending and/or testifying truthfully at deposition or at trial without the necessity of a subpoena or compensation. All reasonable travel expenses incurred by you in rendering such assistance will be reimbursed by Apache. Employee’s compliance with the obligations of this paragraph shall not interfere with his future employment or enterprise, and shall not be so extensive or intrusive that Employee incurs economic damage as a result of his compliance.

Non-solicitation: Because of the confidential information shared with Employee and in exchange for the payments described herein, for a period of two years following the Resignation date, Employee, and his assigns, agree not to directly or indirectly solicit any employee of Apache for employment elsewhere (i.e., employment with any person or entity other than Apache).
