The Nuverra Environmental Solutions, Inc. 2017 Long Term Incentive Plan (the “Incentive Plan”) is intended to provide for the grant of equity-based awards to designated members of the Company’s management and employees. The maximum number of shares of the Company’s common stock that is available for the issuance of awards under the Incentive Plan is 1,772,058. As of June 30, 2020, approximately 771,000 shares were available for issuance under the Incentive Plan.

The 2018 Restricted Stock Plan for Directors (the “Director Plan”) provides for the grant of restricted stock to the non-employee directors of the Company.
