The Compensation and Human Resources Committee of the Board of Directors (the “Committee”) granted to Employee on March 3, 2014 (“Effective Date”), a Performance Award of a designated number of performance units, each of which has a designated value equivalent to Dynegy’s Stock Price as of the Effective Date. No portion of the Performance Units will be earned if the Company’s performance is below the Minimum level of performance. The performance criteria are designated in Section 3 and on Exhibit 1 to this Agreement.

3.Performance Period and Performance Goals. Subject to the provisions of Sections 5 and 6 of this Agreement, the performance period for purposes of determining whether the Performance Award will be paid shall be January 1, 2014 through December 31, 2016 (the “Performance Period”). The Performance Criteria for purposes of determining whether, and the extent to which, the Performance Award will be paid are set forth in Exhibit 1 to this Agreement, which Exhibit is made a part of this Agreement.

4.Payment. Subject to the provisions of Sections 5 and 6 of this Agreement, following the end of the Performance Period, Employee shall be entitled to receive the payment of an amount not exceeding the maximum value of the Performance Award, based on the achievement of the Performance Criteria set forth in Exhibit 1 for such Performance Period, as determined and certified in writing by the Committee. Payment of the Performance Award may be made in a lump sum in Dynegy Common Stock and shall be made not earlier than January 22, 2017 and not later than March 15, 2017 or such other time as complies with Code Section 409A.

5.Termination. The Performance Award shall terminate if Employee does not remain continuously in the employ of the Company or does not continue to perform services as a Consultant or Director for the Company at all times during the Performance Period, except that:

(a)if the Employee is determined to be disabled (as defined in the Company’s long term disability program or plan in which the Employee is a participant or, if the Employee does not participate in any such plan, as defined in the Dynegy Inc. Long Term Disability Plan, as amended, or the successor plan thereto) or in the event of the death of the Employee, all Performance Units shall become vested at Target level of performance. In such case, Employee or Employee’s legal representative, or the person, if any, who acquired the Performance Award by bequest or inheritance or by reason of the death of Employee, shall be entitled to receive any payment with respect to the Performance Award in accordance with this Agreement, or

(b)if the Employee’s employment with the Company terminates by reason of Involuntary Termination, then the Performance Units shall become vested at Target level of performance by multiplying the payment by a fraction, the numerator of which shall be the number of calendar days that elapsed between the date of Employee’s termination and the Effective Date and the denominator of which shall be 1,080 but in no case shall such fraction be greater than one (1), or

(c)if the Employee’s employment with the Company terminates by reason of retirement following the date on which such Employee has (I) reached sixty (60) years of age and (II) completed at least ten (10) years of service as an employee of the Company, then the Performance Unites shall become vested upon completion of the performance period based upon actual level of performance by multiplying the payment by a fraction, the numerator of which shall be the number of calendar days that elapsed between the date of Employee’s termination and the Effective Date and the denominator of which shall be 1,080 but in no case shall such fraction be greater than one (1).

(d)For purposes of this Agreement, the following terms shall have the meanings indicated below:

6.Corporate Change. If a Corporate Change occurs during the Performance Period, provided the ending share would entitle Employee to receive a Performance Award based upon the performance goals set forth in Exhibit 1 to this Agreement Employee shall receive a payment with respect to the Performance Award, which shall be determined by using either, as applicable (a) the agreed price per share received by the shareholders of Dynegy as a result of the Corporate Change, or if there is no agreed price per Share, then (b) the average closing Dynegy Inc. share price for the twenty (20) consecutive trading days immediately preceding the effective date of the Corporate Change, as the ending Share price for the Performance Period. Such payment, if any, shall be made regardless of whether Employee’s employment with the Company is terminated (other than for Cause) on or after the effective date of such Corporate Change, and shall be made in stock or cash to Employee as soon as administratively feasible but no later than the later of December 31 of the calendar year in which the Corporate Change occurs or the 15^th day of the third month following the effective date of the Corporate Change. The Performance Period shall end as of the effective date of a Corporate Change, and any Performance Award payments hereunder shall only be made in accordance with this Section. Notwithstanding anything contained herein to the contrary, any Corporate Change within the first twelve (12) months of the Performance Period would entitle Employee to receive a Performance Award at Target level of performance.

7.Status of Stock. Employee agrees that any Shares distributed pursuant to this Agreement will not be sold or otherwise disposed of in any manner which would constitute a violation of any applicable federal or state securities laws. Employee also agrees that (a) the certificates representing the Shares may bear such legend or legends as the Committee in its sole discretion deems appropriate in order to assure compliance with applicable securities laws and (b) the Company may refuse to register the transfer of the Shares on the stock transfer records of the Company, and may give related instructions to its transfer agent, if any, to stop registration of such transfer, if such proposed transfer would in the opinion of counsel satisfactory to the Company constitute a violation of any applicable securities law.

8.Employment Relationship. For purposes of this Agreement, Employee shall be considered to be in the employment of the Company as long as Employee remains an employee of the Company or an

Affiliate (as such term is defined in the Plan). Nothing in the adoption of the Plan or the grant of the Performance Award thereunder pursuant to this Agreement shall confer upon Employee the right to continued employment by the Company or affect in any way the right of the Company to terminate such employment at any time. Unless otherwise provided in a written employment agreement or by applicable law, Employee’s employment by the Company shall be on an at-will basis, and the employment relationship may be terminated at any time by either Employee or the Company for any reason whatsoever, with or without cause. Any question as to whether and when there has been a termination of such employment, and the cause of such termination, shall be determined by the Committee in its sole discretion, and its determination shall be final and binding on all parties.

9.Withholding of Tax. To the extent that payment of the Performance Award results in compensation income to Employee for federal or state income tax purposes, the Company is authorized to withhold from any cash or Stock distributable to the Employee under this Agreement, then or thereafter payable to Employee any tax required to be withheld by reason of such resulting compensation income.

10.Code Section 409A. If it is subsequently determined by the Committee, in its sole discretion, that the terms and conditions of this Agreement and/or the Plan are not compliant with Code Section 409A, or any Treasury regulations or Internal Revenue Service guidance promulgated thereunder, this Agreement and/or the Plan may be amended accordingly.
