2018 Employee Release and Benefits Agreement between Registrant and W. Kregg Olson, effective August 1, 2018

The parties to this Agreement are APACHE CORPORATION (“Apache”) and W. Kregg Olson (“Employee”).

On April 16, 2018, Employee informed Apache of his intention to retire as Executive Vice President, Corporate Reservoir Engineering of Apache effective as of August 1, 2018. This document describes the agreements of Apache and Employee concerning the termination of Employee’s employment with Apache due to such retirement. This Agreement and the benefits described below give valuable consideration to both Apache and Employee.

Separation from Service: 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 1, 2018 (the “Retirement Date”).

Benefits: In addition to Employee’s retirement 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 Benefits:

*Dividend equivalents will be settled in cash on each applicable vesting date. For purposes of this Agreement, a dividend equivalent is an amount equal to the cash dividend payable per share of Apache common stock from and after January 7, 2016 through the applicable vesting date multiplied by the applicable Number of Units in the table above for the applicable vesting date.

**Dividend equivalents will be settled in cash on each applicable vesting date. For purposes of this Agreement, a dividend equivalent is an amount equal to the cash dividend payable per share of Apache common stock from and after January 5, 2017 through the applicable vesting date multiplied by the applicable Number of Units in the table above for the applicable vesting.

Further, Employee will become 100% vested in his Target Amount of units upon (i) his death while continuing to vest hereunder, with payment to occur as soon as administratively convenient following the date of death, but in no event later than March 15 of the calendar year immediately following the calendar year in which Employee died; or (ii) upon the occurrence of a 409A Change of Control of the Company (within the meaning of the performance program) while continuing to vest hereunder, with payment to occur within 30 days of such 409A Change of Control.

Employee Acknowledgement: Employee acknowledges that the Benefits are consideration over and above that to which Employee otherwise would be entitled upon retirement, and are paid in consideration for this Agreement.

Release by Employee: In consideration of receipt of the 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), 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 (which Apache agrees will continue beyond the Retirement Date, to the same extent as though Employee were still an executive officer of

Apache), (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; and (10) 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.

Confidentiality: Employee and Apache will keep this Agreement strictly confidential, except that Employee may disclose this Agreement to his spouse, attorneys, bona fide prospective employers, financial and tax advisors and will cause Employee’s spouse, attorneys, bona fide prospective employers, 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 Retirement 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.

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: Employee agrees that, upon request by Apache, Employee will assist Apache in the preparation, prosecution or defense of any claims or potential claims that may be made or threatened to be made against Apache and/or any member of the Apache Parties in any action, suit, or proceeding, whether civil, criminal, administrative, investigative or otherwise with respect to an event or occurrence during Employee’s term of employment (a “Proceeding’), and will assist Apache in the prosecution of any claims that may be made by Apache and/or any member of Released Parties in any Proceeding. Such assistance will include, without limitation, executing truthful declarations or providing information in his possession or recollection requested by Apache and attending and/or testifying truthfully at deposition or at trial without the necessity of a subpoena or compensation. Employee also agrees, unless precluded by law, to promptly inform Apache if Employee is asked to assist in any investigation (whether governmental or otherwise) of Apache and/or any member of Released Parties regardless of whether a lawsuit has been filed against Apache and/or any members of Released Parties with respect to such investigation. Employee agrees to fully and completely cooperate with any investigations conducted by or on behalf of Apache and any member of Released Parties. Apache agrees to reimburse Employee for all reasonable out-of-pocket expenses associated with such assistance, including travel expenses, and agrees to indemnify Employee for all costs and liabilities (including without limitation, legal fees) the same as though Employee were still an executive officer of Apache to the fullest extent permitted by Delaware law for such an executive officer.

Other Agreements: This Agreement, Employee’s retirement benefits, the Grant Agreements between Employee and Apache, and any other executed written agreement between Employee and Apache constitute the entire agreement concerning the termination of Employee’s employment with Apache.
