WHEREAS, COMPANY agrees, in accordance with the terms of this Agreement, to second Stephen Milbourne (“EMPLOYEE”) to MLP;

NOW, THEREFORE, for good and valuable consideration, the Parties agree to the terms of this Agreement.

SECTION 1. SCOPE.

This Agreement sets forth the terms under which COMPANY shall second to MLP from time to time, commencing on the Effective Date, EMPLOYEE, who shall remain for all purposes an employee of COMPANY, but shall be assigned by COMPANY to work on behalf of MLP.

SECTION 2. POSITIONS AND RESPONSIBILITIES.

2.1 Employee to be Seconded From Time to Time. COMPANY hereby agrees to second to MLP EMPLOYEE (the “Seconded Employee”).

2.2 Term. The secondment of the Seconded Employee shall be for a period commencing as of the Effective Date and continuing on a month-to-month basis until terminated as provided herein. Either Party, at its sole option and without cause, may terminate this Agreement at any time by written notice to the other Party given at least thirty (30) days in advance of such termination date. Seconded Employee does not have an employment agreement or contract with either COMPANY or MLP; therefore, the MLP may terminate this Agreement at any time, with thirty (30) days’ notice as provided above, without cost or penalty, and the COMPANY or Seconded Employee may terminate the Seconded Employee’s employment in accordance with applicable law. The discontinuance of the employment relationship of the Seconded Employee with the COMPANY shall constitute a termination of this Agreement.

2.3 Duties of Seconded Employee. COMPANY and MLP agree that the Seconded Employee shall perform services for the benefit of MLP, of a nature and scope as determined and directed by or on behalf of MLP, who shall be responsible for supervision and control of the Seconded Employee with respect to the services provided by the Seconded Employee to MLP. COMPANY and MLP further agree that the majority of the Seconded Employee’s total available working time will be spent performing services for MLP; however, COMPANY and MLP also agree that COMPANY has the right to second the Seconded Employee to perform services for other entities or third parties at

COMPANY’s sole discretion. The Seconded Employee will comply with all policies and procedures of MLP and COMPANY, as applicable.

SECTION 3. RESPONSIBILITY FOR SALARIES, BENEFITS, EMPLOYMENT TAXES AND OTHER COSTS.

Except to the extent the Seconded Employee is performing services for the Company or its other affiliates (or other secondees), in which case employee costs shall be allocated based on methodologies to be reasonably agreed between the Company and MLP, MLP shall pay and reimburse COMPANY, and shall be responsible for such payment and provision of, all salaries, wages, bonuses, benefits, health insurance, dental insurance, life insurance, long-term disability insurance, flex spending accounts, 401(k) matching, profit sharing, payroll taxes and other employment expenses (collectively, “Payment Obligations”) for the Seconded Employee. MLP understands that the Payment Obligations are subject to change from year to year, and agrees to pay and reimburse COMPANY for the Payment Obligations regardless of the nature of any such changes or the reason(s) for any such changes, provided that any material changes to the Seconded Employees’ compensation and benefits shall be subject to the prior approval of the MLP. The foregoing Payment Obligations, to the extent incurred prior to termination of this Agreement, shall survive termination of this Agreement. COMPANY shall continue to have the responsibility for complying with all requirements of all income and tax laws and unemployment compensation laws applicable to the Seconded Employee. COMPANY shall be responsible for providing insurance for all amounts required to be paid by an employer because of injury to, or death of, the Seconded Employee covering the liability of both COMPANY and MLP.

SECTION 4. PAYMENT.

COMPANY will invoice MLP, and MLP agrees to pay COMPANY, on a monthly basis for all Payment Obligations described herein for services rendered by the Seconded Employee to MLP for providing the services and accommodations described herein.
