LONG TERM INCENTIVE PLAN

ANNUAL PERFORMANCE UNIT AWARD AGREEMENT FOR SENIOR OFFICERS

Enable Midstream Partners, LP (the “Partnership”) is pleased to inform you, [NAME OF GRANTEE], that, subject to acceptance by you through the online acceptance procedures set forth within Fidelity’s website at xxx.xxxxxxxxxxx.xxx, you have been granted Performance Units under the Enable Midstream Partners, LP Long Term Incentive Plan (the “Plan”) in the target number set forth below, subject to the terms and conditions of the this Annual Performance Unit Award Agreement For Senior Officers (this “Agreement”) and the Plan (this “Award”). Capitalized terms in this Agreement not otherwise defined herein shall have the meanings set forth in the Plan. The material terms of this Award are as follows:

1. Number of Performance Units. You have been granted the target number of Performance Units of [NUMBER OF TARGET UNITS] (“Target Performance Units”), subject to your acceptance of this Award as provided in Section 16 below. Appendix I describes the manner in which the total number of Performance Units (if any) that you earn will be calculated (subject to the vesting requirements described below). The actual number of Performance Units earned under this Award may be more or less depending on the Partnership’s performance as described in this Agreement and Appendix I.

2. Date of Grant. The grant date of the Performance Units is [DATE] (“Date of Grant”).

3. Vesting and Payment of Award. The Performance Units are subject to a vesting requirement (in addition to the performance requirement described in Appendix I). The Performance Units earned as described in Appendix I shall become vested on the distribution date of the Award following the end of the Performance Period (the “Vesting Date”), provided that your Employment continue at all times from the Date of Grant up to and including the Vesting Date. The Vesting Date will be no earlier than January 1st and no later than June 30th, each of the calendar year immediately following the end of the Performance Period. The foregoing notwithstanding, if you have a Qualifying Termination (as defined below) before the Vesting Date, you may vest in all or portion of this Award as described in Section 4. On the Vesting Date you will be paid Units equal to the number of earned Performance Units (and your Performance Units will be cancelled on the Vesting Date), which will be transferred to a third-party non-retirement brokerage account established for you at Fidelity (your “Brokerage Account”). In addition, at the time of such payment in respect of the earned Performance Units, you will also be paid a cash distribution equivalent payment in an amount equal to the product of: (i) the number of Units paid to you; and (ii) the aggregate amount of DERs for the DER Period, without interest.

4. Termination of Employment Prior to Vesting Date.

a. Forfeiture of Performance Units Upon Termination. In the event your Employment is terminated for any reason other than a Qualifying Termination or Retirement prior

to the Vesting Date, the Performance Units shall automatically and immediately be forfeited and cancelled on the date of such termination.

b. Disability or Termination Due To Death. If, prior to Vesting Date, you experience a Disability or a Qualifying Termination as a result of your death, then you will earn your Target Performance Units as of the date of your Qualifying Termination or Disability. Units equal to your Target Performance Units will be paid to you or your beneficiary (and your Performance Units will be cancelled upon such payment date) by transfer to your Brokerage Account, along with a cash payment to you or your beneficiary in the amount of the DERs (as described in Section 3), as soon as practicable following, but in no event more than 30 days after, such termination date or disability date.

c. Retirement.

i. If you terminate your Employment due to your Retirement prior to the end of the Performance Period, then you will earn a pro rata number of your Target Performance Units, with such number determined by multiplying the full number of Target Performance Units granted under this Award by a fraction, the numerator of which is the number of calendar days during the period beginning on the first day of the Performance Period and ending on the date of your Retirement and the denominator of which is the number of calendar days during the Performance Period (rounded up to the next whole number). All Performance Units not earned by the foregoing shall automatically and immediately be forfeited and cancelled on the date of your Retirement. Except as provided below, the Units equal to your number of Target Performance Units earned as provided above will be paid to you (and your Performance Units will be cancelled upon such payment date) by transfer to your Brokerage Account, along with a cash payment to you in the amount of the DERs (as described in Section 3), as soon as practicable following, but in no event more than 30 days after, such termination date. The foregoing to the contrary notwithstanding, if as of the date of your Retirement you are a “specified employee” (within the meaning of Section 409A of the Code) as determined by the Partnership, then payment of the Units and DERs earned by you due to your Retirement will be paid to you on the earlier of (1) the date that is six months and two days following the date of your Retirement or (2) the date of your death.

ii. If you terminate your Employment due to your Retirement after the end of the Performance Period but prior to the Vesting Date, then you will earn the Performance Units as provided in Appendix I and the resulting Units will be paid to you (and the Performance Units will be cancelled) as provided in Section 3.

5. Change of Control Event. If a Change in Control (as defined in the Plan) occurs prior to the end of the Performance Period and (i) your Employment has not terminated as of the Vesting

Date or (ii) you experience a Qualifying Termination other than due to death before the Vesting Date, then you will earn Performance Units equal to the greater of: (1) your Target Performance Units or (2) the number of Performance Units earned as provided in Appendix I and the resulting Units will be paid to you (and the Performance Units will be cancelled) as provided in Section 3.

6. Definitions. As used in this Agreement, the following capitalized terms have the following meanings:
