I have read this Waiver and Release and the Plan (which, together, are referred to herein as the "Plan Materials") and the Plan is incorporated herein by reference. The provision of the Benefits is voluntary on the part of the Company and is not required by any legal obligation other than the Plan. I choose to accept this offer.

I understand that, in order to be eligible for the Benefits, I must sign (and return to Human Resources Manager, Pioneer Energy Service Corp., 1250 N.E. Loop 410, Suite 1000, San Antonio, Texas 78209) this Waiver and Release by 5:00 p.m. on April 30, 2015.

I acknowledge that payment of Benefits to me by the Company is not an admission by the Company or any other member of the Corporate Group that they engaged in any wrongful or unlawful act or that the Company or any member of the Corporate Group violated any federal or state law or regulation.

Should any of the provisions set forth in this Waiver and Release be determined to be invalid by a court, agency or other tribunal of competent jurisdiction, it is agreed that such determination shall not affect the enforceability of other provisions of this Waiver and Release. I acknowledge that this Waiver and Release and the other Plan Materials set forth the entire understanding and agreement between me and the Company or any other member of the Corporate Group concerning the subject matter of this Waiver and Release and supersede any prior or contemporaneous oral and/or written agreements or representations, if any, between me and the Company or any other member of the Corporate Group. I understand that for a period of seven calendar days following the date that I sign this Waiver and Release, I may revoke my acceptance of the offer referred to above, provided that my written statement of revocation is received on or before that seventh day by Human Resources Manager, Pioneer Energy Services Corp., 1250 N.E.

In the event I revoke my acceptance of the offer referred to above, the Company shall have no obligation to provide me the Benefits. I understand that failure to revoke my acceptance of the offer referred to above within seven calendar days from the date I sign this Waiver and Release will result in this Waiver and Release being permanent and irrevocable.

By execution of this document, I do not waive or release or otherwise relinquish any legal rights I may have which are attributable to or arise out of acts, omissions or events of the Company or any other member of the Corporate Group which occur after the date of the execution of this Waiver and Release.
