On May 24, 2016, the stockholders of Superior Energy Services, Inc. (the “Company”) approved the 2016 Incentive Award Plan (the “Plan”) and the Plan became effective. The purpose of the Plan is to attract, retain and motivate persons who make (or are expected to make) important contributions to the Company by providing these individuals with equity ownership opportunities.

The Compensation Committee (the “Compensation Committee”) of the Company’s Board of Directors (the “Board”) (or a subcommittee thereof) will administer the Plan and has the authority to grant awards under the Plan, including setting the terms and conditions of the awards. The Compensation Committee will also have the authority to interpret the Plan, to adopt, amend and repeal administrative rules, guidelines and practices relating to the Plan that it determines to be appropriate and to make any other determination that it believes necessary or advisable for proper administration of the Plan.

The types of awards that may be granted under the Plan include stock options, restricted stock, restricted stock units, stock appreciation rights and other stock or cash based awards. The aggregate number of shares of the Company’s common stock which may be issued pursuant to awards granted under the Plan is the sum of (i) 5,000,000 shares, plus (ii) any shares which, as of May 24, 2016, remained available for issuance under the Company’s Amended and Restated 2013 Stock Incentive Plan (the “Prior Plan”, plus (iii) any shares subject to awards outstanding under the Prior Plan as of May 24, 2016 which, on or after May 24, 2016, are forfeited or otherwise terminate or expire for any reason without the issuance of shares. In no event may the number of shares of the Company’s common stock issued pursuant to the exercise of incentive stock options under the Plan exceed 1,000,000 shares. No individual may be granted awards covering more than 1,000,000 shares of the Company’s common stock under the Plan in any fiscal year. Further, with respect to awards payable in cash and not denominated in shares of common stock, the maximum value that may become payable to a participant in any fiscal year is $10,000,000. In addition, the maximum aggregate grant date fair value of awards granted to any non-employee director during any fiscal year of the Company may not exceed $400,000.

The Plan also contains provisions with respect to payment of exercise or purchase prices, vesting and expiration of awards, adjustments and treatment of awards upon certain corporate transactions, including stock splits, recapitalizations and mergers, transferability of awards and tax withholding requirements. The Plan may be amended, suspended or terminated at any time by the Board, subject to the requirement that certain amendments may require stockholder approval. In addition, no amendment may materially impair an award previously granted and still outstanding without the consent of the recipient.
