Except as may be provided in any indemnification agreement between Executive and the Company and/or FracRock International, Inc. (“FracRock”), the predecessor of the Company’s subsidiary, EcoStim International, Inc., and any plan and/or award agreement under which Executive was granted any equity or equity-based award with the Company and its subsidiaries and their respective predecessors, the terms of this Agreement are intended by the Parties to be the final expression of their agreement with respect to the employment of Executive by the Company and supersede all prior understandings and agreements, whether written or oral, including, but not limited to, the Prior Employment Agreement. In the event of a conflict between this Agreement and any such indemnification agreement, it is intended that the agreement that grants Executive greater rights shall govern. Notwithstanding the foregoing, this Agreement will not in any way affect any equity or equity-based awards that may be granted to Executive, which are governed by the applicable plan and/or award agreements under which they were granted, except to the extent expressly provided for in such agreement or plan. The Parties further intend that this Agreement shall constitute the complete and exclusive statement of its terms and that no extrinsic evidence whatsoever may be introduced in any judicial, administrative, or other legal proceeding to vary the terms of this Agreement.
