 Apache Corporation 

Amendment to Stock Option Award Agreements 

This Amendment to the Stock Option Award Agreements is entered into in connection with the Participant's separation from service with Apache
Corporation (together with it Affiliates, the "Company") effective March 31, 2014 (the "Separation Date") and the terms of the separation agreement between the Participant and the Company dated February 11, 2014 (the "Separation
Agreement") and governs all outstanding Options under the Plan and the Agreements, determined as of the Separation Date, between the Company and the Participant. 
  

	 	1.	Section 4 of each of the Agreements is hereby amended to add a new paragraph at the end thereof, which shall read as follows: 


Separation Agreement. Notwithstanding the provisions of Section 4 of any Agreement or the provisions of the Grant Notices or the
Plan to the contrary, for purposes of the Option, the Participant's employment shall be deemed to continue with the Company following the Separation Date provided that the Participant remains in compliance with the provisions of the Separation
Agreement. The Participant shall immediately notify the Company of any future change in address or other contact information. Notwithstanding the foregoing provisions of this paragraph, the Participant shall not be treated as continuing in
employment with the Company following the Separation Date for purposes of the Change of Control provisions of this Agreement, the Grant Notice or the Plan. 
  

	 	2.	The remaining terms of the Agreements and the Plan shall continue in full force and effect. 

  

	 	3.	This Amendment may be executed in one or more counterparts, and by the different parties hereto in separate counterparts, each of which when executed shall be deemed to be an original but all of which taken together
shall constitute one and the same agreement. 

  

	 	4.	If any provision of this Amendment is held invalid or unenforceable, the remainder of this Amendment shall nevertheless remain in full force and effect, and if any provision is held invalid or unenforceable with respect
to particular circumstances, it shall nevertheless remain in full force and effect in all other circumstances, to the fullest extent permitted by law.
