CUSIP No. 29272B 105 Schedule 13D

Performance-Based Restricted Stock Agreement

On September 18, 2015 Mr. Ravichandran and the Issuer entered into a Performance-Based Restricted Stock Agreement which provides an opportunity for Mr. Ravichandran to earn a fully vested right to up to 3,693,754 shares of Common Stock (collectively, the “Award Shares”) over a three year period beginning on July 1, 2015 and ending on June 30, 2018 (the “Performance Period”). Award Shares may be earned based on the Issuer achieving pre-established threshold, target and maximum levels of free cash flow per share, which is defined in the award agreement as Unlevered Free Cash Flow (as reported), as defined in the Issuer’s Form 8-K filed on August 4, 2015, less interest paid, divided by the number of outstanding shares of Common Stock (excluding the Award Shares) at the end of the applicable Performance Quarter or Performance Year, each as defined below.

Award Shares may be earned during each calendar quarter during the Performance Period (each, a “Performance Quarter”) if the Issuer achieves a threshold, target or maximum level of free cash flow per share for the Performance Quarter. If free cash flow per share is less than the threshold level for a Performance Quarter, no Award Shares will be earned during that Performance Quarter. Award Shares that were not earned during a Performance Quarter may be earned later during the then current twelve month period from July 1^st to June 30^th during the Performance Period (each, a “Performance Year”) at a threshold, target or maximum level of free cash flow per share for the Performance Year.

Only one-third of the Award Shares are generally eligible to be earned in any Performance Year while Mr. Ravichandran is employed by the Issuer In order to account for the potential concentration of growth capital expenditures in a particular Performance Year, in certain instances free cash flow per share that exceeds the threshold level for a later Performance Year (in the event that the threshold level for the immediately preceding Performance Year was not met) or that exceeds the maximum level for a later Performance Year can be applied to earn Award Shares that were not earned in the immediately preceding Performance Year. However, free cash flow per share may not be applied to more than one Performance Year.

If free cash flow per share for the Performance Period is at the target level throughout the entire Performance Period, Mr. Ravichandran would earn 2,350,571 of the Award Shares for the Performance Period. If free cash flow per share is above the threshold level but below the target level for the Performance Period, he would earn fewer Award Shares, and if it is above the target level for the Performance Period, he would earn up to the maximum number of the Award Shares.

If there is a Change in Control (as defined in Mr. Ravichandran’s employment agreement) while Mr. Ravichandran is employed by the Issuer or Mr. Ravichandran’s employment is terminated due to death or disability (as defined in Mr. Ravichandran’s employment agreement) during a given Performance Quarter, Mr. Ravichandran will be entitled to any Award Shares earned for previous Performance Quarters, together with a number of Award Shares equal to the target level of Award Shares for that Performance Quarter and for any additional remaining Performance Quarters during the Performance Period.

If the Issuer terminates Mr. Ravichandran’s employment without cause or he resigns for good reason (as such terms are defined in his employment agreement), Mr. Ravichandran will be entitled to any Award Shares earned for previous Performance Quarters, together with the number of Award Shares that are earned for the Performance Quarter in which his employment ends (but no less than the target number of Award Shares for such Performance Quarter).

Except as described above, Mr. Ravichandran must be employed at the end of the Performance Period (June 30, 2018) in order to become vested in any Award Shares that have been earned under the Performance-Based Restricted Stock Award. Award Shares that have been earned based on free cash flow per share performance as described above will be forfeited if, prior to a Change in Control, Mr. Ravichandran resigns without good reason or his employment is terminated by the Issuer for cause before the end of the Performance Period.

The foregoing description of the Performance-Based Restricted Stock Agreement is qualified in its entirety by reference to the form of award agreement, which is filed as Exhibit 10.7 to this Schedule 13D and incorporated herein by reference.

Other Equity Agreements

Mr. Ravichandran is also party to the following additional agreements with the Issuer:
