Omnibus Incentive Plan, Seventy Seven Energy Inc. Amended and Restated 2014 Incentive Plan, Seventy Seven Energy Inc. Retirement and Savings Plan and Seventy Seven Energy Inc.

On April 20, 2017, pursuant to the Agreement and Plan of Merger, dated as of December 12, 2016 (the “Merger Agreement”), by and among Patterson-UTI Energy, Inc.
