Pursuant to this Restricted Stock Unit Award Agreement (this “RSU Award Agreement”), CENTERPOINT ENERGY, INC. (the "Company") hereby grants to [Name] (the “Participant”), effective on [Date] (the “Grant Date”), a restricted stock unit award of [Number] units of Common Stock of the Company (the "RSU Award"), pursuant to the CENTERPOINT ENERGY, INC. 2009 LONG TERM INCENTIVE PLAN (the "Plan"), with such number of units being subject to adjustment as provided in Section 14 of the Plan, and further subject to the terms, conditions and restrictions described in the Plan and as follows:

1.Relationship to the Plan; Definitions. This RSU Award is subject to all of the terms, conditions and provisions of the Plan and administrative interpretations thereunder, if any, which have been adopted by the Committee and are in effect on the date hereof. Except as defined herein, capitalized terms shall have the same meanings ascribed to them under the Plan. To the extent that any provision of this RSU Award Agreement conflicts with the express terms of the Plan, it is hereby acknowledged and agreed that the terms of the Plan shall control and, if necessary, the applicable provisions of this RSU Award Agreement shall be hereby deemed amended so as to carry out the purpose and intent of the Plan. References to the Participant herein also include the heirs or other legal representatives of the Participant.

2.    Establishment of RSU Award Account. The grant of units of Common Stock of the Company pursuant to this RSU Award Agreement shall be implemented by a credit to a bookkeeping account maintained by the Company evidencing the accrual in favor of the Participant of the unfunded and unsecured right to receive a corresponding number of shares of Common Stock, which right shall be subject to the terms, conditions and restrictions set forth in the Plan and to the further terms, conditions and restrictions set forth in this RSU Award Agreement. Except as otherwise provided in Section 10 of this RSU Award Agreement, the units of Common Stock credited to the Participant's bookkeeping account may not be sold, assigned, transferred, pledged or otherwise encumbered until the Participant has been registered as the holder of such shares of Common Stock on the records of the Company as provided in Section 4 or 5 of this RSU Award Agreement.

3.    Vesting of RSU Award. Unless Participant receives a distribution pursuant to Section 4 below, the Participant's right to receive shares of Common Stock under this RSU Award shall vest as follows:

(a)[Number] units of Common Stock of the Company covered under the RSU Award shall vest on the [Years] anniversary of the Grant Date; and

(b)[Number] units of Common Stock of the Company covered under the RSU Award shall vest on the [Years] anniversary of the Grant Date, such that 100% of the RSU Award shall be vested as of the [Years] anniversary of the Grant Date.

The Participant must be in continuous employment with the Company or any of its Subsidiaries ("Employment") from the Grant Date through and as of the applicable vesting date for the Common Stock to vest; otherwise, all such unvested shares as of the date the Participant's Employment terminates for any reason shall be forfeited as of such termination date.

4.    Change in Control.

(a)    Assumption or Substitution. In the event of a Change in Control, the surviving, continuing, successor, or purchasing corporation or other business entity or parent thereof, as the case may be (the "Acquiror"), may, without the Participant’s consent, either assume or continue the Company’s rights and obligations under this RSU Award Agreement or provide a substantially equivalent award in substitution for the units subject to this RSU Award.

(b)    Vesting Upon a Change in Control. Notwithstanding any provision of this RSU Award Agreement to the contrary, upon the occurrence of a Change in Control of the Company, if (i) the Participant's Employment has not terminated prior to such date and (ii) the Acquiror does not assume or continue this RSU Award or provide a substantially equivalent award in substitution for this RSU Award pursuant to Section 4(a), the Participant's right to receive the unvested shares of Common Stock subject to this RSU Award Agreement shall be fully vested.

(c)    Vesting Upon a Covered Termination. Notwithstanding any provision of this RSU Award Agreement to the contrary, if the Participant experiences a Covered Termination prior to the final vesting date, then, upon the date of the Covered Termination, the Participant's right to receive any unvested units of Common Stock subject to this RSU Award Agreement shall be fully vested.

(d)    Distributions Upon a Change in Control. If the Participant is entitled to a benefit pursuant to Section 4(b) or 4(c) hereof in connection with a Change in Control, then this RSU Award shall be settled by a distribution to the Participant of:

(1)the number of shares of Common Stock subject to this RSU Award Agreement not previously vested pursuant to Section 3 above, plus

(2)Dividend Equivalents on such shares of Common Stock in the form of shares of Common Stock (rounded up to the nearest whole share) for the period commencing on the Grant Date and ending on the date immediately preceding the date of the distribution;

with such shares of Common Stock registered in book-entry form with the Company’s transfer agent in the name of the Participant. In lieu of the foregoing distribution in

shares, the Committee, in its sole discretion, may direct that such distribution be made to the Participant in a lump sum cash payment equal to:

(1)the product of (x) the Fair Market Value per share of Common Stock on the date immediately preceding the date of the distribution and (y) the number of shares of Common Stock subject to this RSU Award Agreement not previously vested pursuant to Section 3 above, plus

(2)Dividend Equivalents on such shares of Common Stock for the period commencing on the Grant Date and ending on the date immediately preceding the date of the distribution;

The distribution under this Section 4, whether in the form of shares of Common Stock or, if directed by the Committee, in cash, shall satisfy the rights of the Participant and the obligations of the Company under this RSU Award Agreement in full.

(e)    Timing of Distribution.

(1)No Assumption or Substitution. If the Participant is entitled to a benefit pursuant to Section 4(b), distributions shall be made in accordance with Section 4(d) on the Change in Control Payment Date.

If the Participant is entitled to a benefit pursuant to Section 4(b) on account of a Covered Termination, distributions shall be made in accordance with Section 4(d) not later than the 70th day after the Participant’s Covered Termination except as otherwise provided in Paragraph (3) below.

(3)Delay of Distribution to Certain Participants. With respect to any benefits payable hereunder upon the Participant’s Separation from Service (including a Covered Termination), if as of the Participant’s Separation from Service, the Participant is a “specified employee” (within the meaning of Section 409A(a)(2)(B)), then such benefits shall not be distributed, and no shares of Common Stock shall be registered in book-entry form with the Company’s transfer agent in the name of the Participant, until the date that is the earlier of (x) the second business day following the end of the six-month period commencing on the date of the Participant's Separation from Service or (y) the Participant's date of death, if death occurs during such six-month period.

(i)If the Change in Control is a Section 409A Change in Control, then the Change in Control Payment Date shall be not later than the 70th day after the date the Change in Control is consummated; and

(ii)If the Change in Control is a Non-Section 409A Change in Control, then the Change in Control Payment Date shall be the vesting date(s) on which the units are paid under Section 3 hereof for the number of units indicated in Section 3 assuming continuous Employment by the Participant as of such vesting date(s); provided, however, in the case of the Participant’s death or Separation from Service prior to the vesting date(s), all shares not previously paid shall be paid not later than the 70th day after the date of the Participant’s Separation from Service except as otherwise provided in Section 4(e)(3).

“Covered Termination” means a Separation from Service that occurs within two years after the date upon which a Change in Control occurs and that does not result from any of the following:

(i)death;

For this purpose, an act or failure to act on the part of the Participant will be deemed “intentional” only if done or omitted to be done by the Participant not in good faith and without reasonable belief that his or her action or omission was in the best interest of the Company, and no act or failure to act on the part of the Participant will be deemed “intentional” if it was due primarily to an error in judgment or negligence.

(iv)a significant reduction in the Participant’s qualified retirement benefits, nonqualified benefits and welfare benefits provided to the Participant immediately prior to the date on which a Change in Control occurs; provided, however, that a contemporaneous diminution of or reduction in qualified retirement benefits and/or welfare benefits which is of general application and which uniformly and contemporaneously reduces or diminishes the benefits of all covered employees shall be ignored and not be considered a reduction in remuneration for purposes of this paragraph (iv);

(v)a significant reduction in the Participant’s overall compensation opportunities (as contrasted with overall compensation actually paid or awarded) under a short-term incentive plan, a long-term incentive plan or other equity plan (or in such substitute or alternative plans) from that provided to the Participant immediately prior to the date on which a Change in Control occurs;

(vi)a change in the location of the Participant’s principal place of employment with the Company by more than 50 miles from the location where the Participant was principally employed immediately prior to the date on which a Change in Control occurs; or

(vii)a failure by the Company to provide directors and officers liability insurance covering the Participant comparable to that provided to the Participant immediately prior to the date on which a Change in Control occurs;

provided, however, that no later than 30 days after learning of the action (or inaction) described herein as the basis for a termination of employment for Good Reason, the Participant shall advise the Company in writing that the action (or inaction) constitutes grounds for a termination of his or her Employment for Good Reason, in which event the Company shall have 30 days (the “Cure Period”) to correct such action (or inaction). If such action (or inaction) is not corrected prior to the end of the Cure Period, then the Participant may terminate his or her Employment with the Company for Good Reason within the 30-day period following the end of the Cure Period by giving written notice to the Company. If such action (or inaction) is corrected before the end of the Cure Period, then the Participant shall not be entitled to terminate his or her Employment for Good Reason as a result of such action (or inaction).

Moreover, upon the date of distribution of shares of Common Stock in settlement of such units, the Participant shall also be entitled to receive Dividend Equivalents on such shares of Common Stock for the period from the Grant Date to the date such shares of Common Stock are distributed to the Participant (in accordance with the requirements of Section 409A of the Code, to the extent applicable).

(a)Confidentiality. The Participant acknowledges that in the course of his or her employment with the Company, the Company agrees to provide to the Participant Confidential Information regarding the Company and the Company’s business and has previously provided the Participant other such Confidential Information.

Nothing in this RSU Award Agreement, however, limits or precludes Participant from making a good faith voluntary report, charge, complaint, or claim to or providing truthful testimony and documents as required by law or under oath pursuant to a subpoena, court order, or request by the Equal Employment Opportunity Commission,

the National Labor Relations Board, the Occupational Safety and Health Administration, the Securities and Exchange Commission or any other federal, state, or local government agency or commission (“Government Agencies”). Participant further understands that this RSU Award Agreement does not limit Participant’s ability to communicate with any Government Agencies or otherwise participate in any investigation or proceeding that may be conducted by any Government Agency, including providing documents or other information to the Government Agency, without notice to the Company. For purposes of this RSU Award Agreement, “Confidential Information” shall mean any and all information, data and knowledge that has been created, discovered, developed or otherwise become known to the Company or any of its affiliates or ventures or in which property rights have been assigned or otherwise conveyed to the Company or any of its affiliates or ventures, which information, data or knowledge has commercial value in the business in which the Company is engaged, except such information, data or knowledge as is or becomes known to the public without violation of the terms of this RSU Award Agreement. By way of illustration, but not limitation, Confidential Information includes business trade secrets, secrets concerning the Company’s plans and strategies, nonpublic information concerning material market opportunities, technical trade secrets, processes, formulas, know-how, improvements, discoveries, developments, designs, inventions, techniques, marketing plans, manuals, records of research, reports, memoranda, computer software, strategies, forecasts, new products, unpublished financial information, projections, licenses, prices, costs, and employee, customer and supplier lists or parts thereof.

(b)Return of Property. The Participant agrees that at the time of his or her Separation from Service, he or she will deliver to the Company (and will not keep in his or her possession, recreate or deliver to anyone else) all Confidential Information as well as all other devices, records, data, notes, reports, proposals, lists, correspondence, specifications, drawings, blueprints, sketches, materials, equipment, customer or client lists or information, or any other documents or property (including all reproductions of the aforementioned items) belonging to the Company or any of its affiliates or ventures, regardless of whether such items were prepared by the Participant.

(c)Non-Solicitation and Non-Competition.

(1)Non-Solicitation. For consideration provided under this RSU Award Agreement, including, but not limited to the Company’s agreement to provide the Participant with Confidential Information (as defined in Section 7(a)) regarding the Company and the Company’s business, the Participant agrees that, while employed by the Company and for one year following his or her Separation from Service, he or she shall not, without the prior written consent of the Company, directly or indirectly, (i) hire or induce, entice or solicit (or attempt to induce, entice or solicit) any employee of the Company or any of its affiliates or ventures to leave the employment of the Company or any of its affiliates or ventures or (ii) solicit or attempt to solicit the business of any customer or acquisition prospect

of the Company or any of its affiliates or ventures with whom the Participant had any actual contact while employed at the Company.

(2)Non-Competition. For consideration provided under this RSU Award Agreement, including, but not limited to the Company’s agreement to provide the Participant with Confidential Information regarding the Company and the Company’s business, the Participant agrees that while employed by the Company and for one year following a Separation from Service he or she will not, without the prior written consent of the Company, acting alone or in conjunction with others, either directly or indirectly, engage in any business that is in competition with the Company or accept employment with or render services to such a business as an officer, agent, employee, independent contractor or consultant, or otherwise engage in activities that are in competition with the Company.

(3)Restricted Area. The restrictions contained in this Section 7(c) are limited to a 50-mile radius around any geographical area in which the Company engages (or has definite plans to engage) in operations or the marketing of its products or services at the time of the Participant’s Separation from Service.

(d)Restrictions Reasonable. The Participant acknowledges that the restrictive covenants under this Section 7, for which the Participant received valuable consideration from the Company as provided in this RSU Award Agreement, including, but not limited to the Company’s agreement to provide the Participant with Confidential Information regarding the Company and the Company’s business are ancillary to otherwise enforceable provisions of this RSU Award Agreement that the consideration provided by the Company gives rise to the Company’s interest in restraining the Participant from competing and that the restrictive covenants are designed to enforce the Participant’s consideration or return promises under this RSU Award Agreement. Additionally, the Participant acknowledges that these restrictive covenants contain limitations as to time, geographical area, and scope of activity to be restrained that are reasonable and do not impose a greater restraint than is necessary to protect the goodwill or other legitimate business interests of the Company, including, but not limited to, the Company’s need to protect its Confidential Information.

(e)Violations. If the Participant violates any provision of this Section 7, the Participant shall not be entitled to receive any amounts that would otherwise be payable to the Participant with respect to this RSU Award, and such amounts shall be forfeited. If the Participant violates any provision of this Section 7 after amounts under this RSU Award have been paid or if the Company learns of the violation after amounts under this RSU Award have been paid, the Participant shall repay to the Company the Common Shares (or the equivalent value thereof determined as of the date of the Company’s demand) or the cash received, as the case may be, within thirty (30) days of receiving a demand from the Company for the repayment of the award. Further, the Company shall

be entitled to an award of attorneys’ fees incurred with securing any relief hereunder and/or pursuant to a breach or threatened breach of this Section 7.

9.    Shareholder Rights. The Participant shall have no rights of a shareholder with respect to the shares of Common Stock granted pursuant to this RSU Award, unless and until the Participant is registered as the holder of such shares of Common Stock.

10.    Successors and Assigns. This RSU Award Agreement shall bind and inure to the benefit of and be enforceable by the Participant, the Company and their respective permitted successors and assigns except as expressly prohibited herein and in the Plan. Notwithstanding anything herein or in the Plan to the contrary, the shares of Common Stock are transferable by the Participant to Immediate Family Members, Immediate Family Member trusts, and Immediate Family Member partnerships pursuant to Section 13 of the Plan.

11.    No Employment Guaranteed. Nothing in this RSU Award Agreement shall give the Participant any rights to (or impose any obligations for) continued Employment by the Company or any Subsidiary, or any successor thereto, nor shall it give such entities any rights (or impose any obligations) with respect to continued performance of duties by the Participant.

13.    Section 409A. It is the intent of the Company and the Participant that the provisions of the Plan and this Award Agreement comply with Section 409A of the Code and will be interpreted and administered consistent therewith. Accordingly, (i) no adjustment to the RSU Award pursuant to Section 14 of the Plan and (ii) no substitutions of the benefits under this Award Agreement, in each case, shall be made in a manner that results in noncompliance with the requirements of Section 409A of the Code, to the extent applicable.
