The Compensation Committee (the “Compensation Committee”) of the Board of Directors (the “Board”) of PowerSecure International, Inc., a Delaware corporation (the “Company”), has been evaluating the Company’s executive compensation program over the course of the year in light of Company goals, shareholder feedback and best practices. Based on this evaluation, the Compensation Committee is modifying the incentive compensation structure for Sidney Hinton, President and Chief Executive Officer of the Company, for years 2014 and forward so that equity-based incentives play a more meaningful role, and further align Mr. Hinton’s incentives and interests with the Company’s shareholders. In 2014, the Compensation Committee intends to transition Mr. Hinton’s compensation plan from a cash-only annual incentive program to an incentive program that includes both cash and equity incentives covering annual and multi-year periods. The specific modifications to Mr. Hinton’s annual compensation package will be determined by the Compensation Committee in early 2014.

In conjunction with this plan, on December 5, 2013, the Compensation Committee made a special equity grant to retain Mr. Hinton over a significant multi-year period. This award is intended to acknowledge Mr. Hinton’s track record of successful leadership of the Company and his critical role in the execution of the Company’s growth strategy in future years. Under the award, Mr. Hinton was granted 275,000 restricted shares of Common Stock, par value $.01 per share (the “Restricted Shares”), of the Company that vests in two equal installments: one-half (50%) of the Restricted Shares will vest on the fifth anniversary of the date of grant, and the other half (50%) of the Restricted Shares will vest on the tenth anniversary of the date of grant. The Restricted Shares will not vest prior to these vesting dates if Mr. Hinton voluntarily terminates employment for any reason. Early vesting of these Restricted Shares will only occur in part upon Mr. Hinton’s death or disability (pro rata through the month of such event), or in full in the event Mr. Hinton is terminated by the Company without cause, or in the event of a change in control of the Company.

The foregoing description of the grant of Restricted Shares does not purport to be complete and is qualified in its entirety by reference to the full text of the Restricted Stock Agreement, which is filed herewith as Exhibit 10.1 and incorporated by reference herein.
