Number of Restricted Units Granted:

Enable Midstream Partners, LP (the “Partnership”) is pleased to inform you that you have been granted the number of Restricted Units set forth above under the Enable Midstream Partners, LP Long Term Incentive Plan (the “Plan”). A Restricted Unit is a common unit of the Partnership that is subject to the forfeiture and non-transferability provisions set forth below in this agreement (the “Restrictions”).

Capitalized terms in this Restricted Unit Grant Agreement (the “Agreement”) not otherwise defined herein shall have the meanings set forth in the Plan. The terms of the grant are as follows:

1. Restrictions. During the Restriction Period described in Section 2 below, none of the Restricted Units granted under this Agreement are transferable (by operation of law or otherwise) by you, other than by will or the laws of descent and distribution and shall be subject to a risk of forfeiture, except as provided herein. If, in the event of your divorce, legal separation or other dissolution of your marriage, your former spouse is awarded ownership of, or an interest in, all or part of any Restricted Units granted hereby to you that have not yet vested, such awards shall automatically and immediately be forfeited and cancelled.

2. Restriction Period.

(a) The Restrictions described in Section 1 above shall commence on the Date of Grant and, except as provided herein, shall lapse on the fourth anniversary of the Date of Grant provided that you remain an Employee on such date (the “Restriction Period”).

(b) Notwithstanding Section 2(a) above, the Restrictions shall lapse before the expiration of the Restriction Period provided as follows:

(i) If the Partnership terminates your employment after the first anniversary of your date of hire, for any reason other than for Cause, the Restrictions shall lapse on your termination of employment, but only with respect to the greater of: (1) fifty percent (50%) of the Restricted Units granted herein or (2) a pro rata number of the Restricted Units granted herein, based upon the number of days you remained employed during the Restriction Period, and all Remaining Units shall automatically and immediately be forfeited and cancelled on the date of your termination.

(ii) If you experience a Qualifying Termination prior to the expiration of the Restriction Period, the Restrictions shall lapse on the date of your Qualifying Termination.

(iii) If you terminate your employment with the Partnership and its Affiliates prior to the expiration of the Restriction Period due to your Retirement, the Restrictions shall lapse on the date of your Retirement, but only with respect to a pro rata number of Restricted Units based upon the number of days you remained an Employee during the Restriction Period, and all remaining Restricted Units shall automatically and immediately be forfeited and cancelled on the date of your Retirement.

(c) In the event your status as an Employee is terminated prior to the time that the Restrictions on the Units lapse as described in Section 2(a) or Section 2(b) above, the Restricted Units shall automatically and immediately be forfeited and cancelled on the date of such termination.

3. Evidence of Grant. The Restricted Units will be evidenced, at the sole option and in the sole discretion of the Committee, either (i) in book-entry form in your name in the Unit register of the Partnership or (ii) a Unit certificate issued in your name. Certificates representing the Units acquired under this Agreement may bear such legend or legends as the Committee deems appropriate. If the Restricted Units are evidenced by a certificate, the Partnership may hold the certificate for safekeeping until the forfeiture occurs or the Restrictions lapse pursuant to the terms of this Agreement.

4. Voting Rights and Distributions. You shall have such voting rights as are applicable to a Unit. You shall also have a right to receive all distributions paid during the Restriction Period with respect to the Restricted Units granted herein as provided in this Section 4.

Such cash payment will equal (i) the number of Restricted Units awarded to you under this Agreement for which the Restrictions have lapsed multiplied by (ii) the aggregate amount of distributions per Unit paid to the Partnership’s unitholders on Units during the Restriction Period (or, during the period from the beginning of the Restriction Period through the date of your termination as provided in Section 2(b) above, if applicable), without interest.

Nothing in this Agreement or in the Plan shall confer any right to you to remain an Employee or restrict the Partnership, the Company or their Affiliates, as applicable, from terminating your employment at any time. Employment with an Affiliate of the Partnership or an Affiliate of the Company shall be deemed to be employment with the Partnership for purposes of the Plan.

For purposes of this paragraph, unless you make other arrangements or are subsequently notified to the contrary, the Partnership or applicable Affiliate will satisfy your obligations with respect to any applicable tax withholding by withholding a number of vested Units having a then-fair-market value equal to such tax withholding obligations.

10. Non-issuance of Units if Violation of Law or Policy. Notwithstanding any other provision of this Agreement, the Partnership shall not be obligated to deliver to you any unrestricted Units if counsel to the Partnership determines such delivery would violate any law or regulation of any governmental authority or agreement between the Partnership and any national securities exchange upon which the Units are listed or any policy of the Partnership or any Affiliate.

11. Incorporation of the Plan. The Restricted Units issued pursuant to this Agreement are subject to the terms of the Plan, which is hereby incorporated by reference as if set forth in its entirety herein, including, without limitation, the ability of the Partnership as provided in the Plan, in its discretion, to amend your Restricted Unit awards without your approval. In the event of a conflict between the terms of this Agreement and the Plan, the Plan shall be the controlling document.

12. Acceptance of Award. By execution of this Agreement, you accept the award evidenced hereby, acknowledge receipt of a copy of the Plan (a copy of which is attached as Exhibit A), represent that you are familiar with the terms and provisions thereof and agree to be bound thereby.
