1.2 Beginning as of the Effective Date, Employee shall be employed as Senior Vice President and Chief Marketing Officer of Employer, and President of Crestwood Services. Employee shall also serve in such other executive capacities as may be reasonably requested from time to time by Employer or the Board of Directors (the “Board”) of the Employer, and shall report directly to the Chief Executive Officer of the Employer. Employee’s duties shall include being responsible for the Employer’s Kansas City office, including, but not limited to, decision-making authority over the operations, which shall include without limitation shared-services functions such as Environment, Safety, Regulatory, Human Resources, Project Management, Insurance, Supply Chain, and over management and budgets of the Kansas City office and Crestwood Services, including all crude and natural gas liquids marketing and all natural gas liquids operations. Notwithstanding the foregoing, to the extent centralized shared services exist within the Pipeline Services Group, Crestwood Services will have the right to use those services on a fee-based basis and Crestwood Services will not unreasonably avoid or decline to use those shared services. Employee agrees to perform diligently and to the best of Employee’s abilities, and in a trustworthy, competent, businesslike, and efficient manner, the duties and services pertaining to any such position as reasonably determined by Employer, as well as such additional or different duties and services that Employee from time to time may be reasonably directed to perform by Employer. Employee shall, during the period of Employee’s employment by Employer, devote Employee’s full business time, energy, and best efforts to the business and affairs of Employer, including the representation of Employer in civic and community leadership roles.

2. As a retention payment to Employee and to induce Employee to agree to the terms and conditions of the Employment Agreement as amended hereby, Employer will pay to Employee $288,187.50 on or before May 29, 2015.

3. Effective as of the Amendment Date, the final four sentences of Section 2.1 of the Employment Agreement are hereby amended to be replaced by and read as follows:

Thereafter, the target annual bonus for Employee will be equal to 90% of Employee’s Base Salary and shall be subject to such terms and conditions as are established by the Board (including, if applicable, its Compensation Committee) for awards of annual bonuses made to similarly situated executives of the Employer. Employee must be employed by Employer at the time a Bonus is declared as a condition of receiving any such Bonus.

5. The Employer and Employee acknowledge and agree that as the result of a corporate restructuring effective on the Effective Date, Employee Cause exists as that term is defined in Section 3.3(a)(i) of the Employment Agreement and the Award Agreements. The Employer and Employee agree that Employee will not invoke these provisions, but shall be permitted to submit a notice of resignation at any time during the period commencing on the Effective Date provided, however, that any such resignation shall not be effective until (i) sixty (60) days after written notice of resignation has been delivered to the Employer or the effective date of a sale or any change of control or ownership in Crestwood Services or any other business of Employer that Employee is managing, whichever occurs earlier, and (ii) Employee works diligently and reasonably during the 60-day period to attempt to locate and hire a successor and to transition his duties to such successor. Employee may submit a notice of resignation for any reason, including, without limitation, because of or in connection with the actual or anticipated sale or any change of control or ownership in Crestwood Services or any other business of Employer that Employee is managing. Employer hereby waives the notice requirements set forth in the last sentence of Section 3.3(a)(i) and the provisions in the Award Agreements related to Employee Cause. In the event Employee resigns as provided in the preceding sentence, Employee shall be entitled to receive the Severance Benefits provided in Section 3.3(b) of the Employment Agreement and the full vesting of restricted units under the Award Agreements as though Employee had resigned for Employee Cause. By entering into this First Amendment, Employee does not in any way waive the existence of Employee Cause, as defined in Section 3.3(a)(i) of the Employment Agreement and the Award Agreements and as a result of the aforementioned corporate restructuring, or any rights of Employee associated with such Employee Cause, including, but not limited to, the Severance Benefits set forth in Section 3.3(b) of the Employment Agreement of full vesting of restricted units under the Award Agreements.

6. Effective as of the Amendment Date, the second sentence in Section 4.1 of the Employment Agreement is hereby amended to be and read as follows:

Therefore, in exchange for the consideration specified herein and as a material incentive for Employer to enter into this Agreement, and to enforce Employee’s obligations regarding confidentiality pursuant to Section 4.5 hereof, Employee hereby agrees that during the term of Employee’s employment hereunder (including any period of employment in which Employee has reduced or altered duties pursuant to Section 3.7) and, in the event of a termination of Employee’s employment pursuant to Section 3.3 (Good Leaver Termination), for a period of twelve (12) months following the Termination Date (the “Non-Compete Period”), Employee shall not, within fifty (50) miles of any location in North America where Employer or any Related Entity has crude or natural gas liquids operations, act or engage in material competition with the activities or plans of Employer or any Related Entity as they exist up to the time of Employee’s termination of employment.

7. Effective as of the Amendment Date, the definition of “Non-Solicitation Period” set forth in Section 4.2 of the Employment Agreement is hereby amended to be and read as follows: “a period of twelve (12) months following the Termination Date.”

8. The Employment Agreement remains and continues in full force and effect in accordance with the provisions thereof, as amended by this First Amendment, and the Employment Agreement as amended shall be read and taken and construed as one and the same instrument.

9. This First Amendment may be executed in one or more counterparts, each of which shall be deemed to be an original but all of which together shall constitute one and the same instrument.

IN WITNESS WHEREOF, the Parties hereto have executed this First Amendment effective as of the Amendment Date.
