Contractor and the Company may be referred to herein individually as a “Party” and collectively as the “Parties.”

WHEREAS, on October 12, 2015, Contractor’s Affiliate, Casper Crude to Rail Holdings, LLC, a Delaware limited liability company (“Seller”), and USDP CCR LLC, a Delaware limited liability company “Buyer”), entered into a Membership Interest Purchase Agreement (as amended or otherwise modified, the “Membership Interest Purchase Agreement”), pursuant to which Seller agreed to sell all of the issued and outstanding membership interests of the Company to Buyer; and

WHEREAS, prior to the Closing, Contractor operated the Company and provided certain services with respect to the Company; and

WHEREAS, to effect the orderly transfer of the Company from Seller to Buyer, Buyer desires that Contractor provide to the Company certain transition services in accordance with the terms of this Agreement.

NOW, THEREFORE, for and in consideration of the mutual covenants set forth herein and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties agree as follows:

1.DEFINITIONS. Unless otherwise defined in this Agreement, capitalized terms in this Agreement have the meanings given to such terms in the Membership Interest Purchase Agreement.

1.    SCOPE OF SERVICES. Effective as of the Closing Date, Contractor will provide to the Company the services described on Exhibit A attached hereto (each, a “Service” and collectively, the “Services”).

2.    INFORMATION. The Company agrees to provide Contractor in a timely manner with any information reasonably necessary for Contractor to provide the Services hereunder.

3.    LIMITATION ON SERVICES. Notwithstanding anything to the contrary in this Agreement, in no event shall Contractor be obligated hereunder in connection with the performance of its obligations under this Agreement to: (a) unless otherwise agreed to between the Parties in writing, provide Services that Contractor did not perform for the Company prior to the Closing Date or perform any such Services in a manner substantially different from the manner in which Contractor performed such Services for the Company prior to the Closing Date; (b) provide any records, information, or data in any form or format except that in which Contractor currently maintains such records, information, or data; (c) make modifications to its existing systems or properties; (d) acquire additional assets, equipment, rights, or properties (including computer equipment, software, furniture, furnishings, fixtures, machinery, vehicles, tools and other tangible personal property) that are not in the ordinary course of operations of Contractor; (e) hire additional employees; (f) pay any costs related to the transfer or conversion of data from Contractor or its Affiliates to the Company;

or (g) incur any obligations or liabilities, except, in each case, as expressly set forth in this Agreement or the Membership Interest Purchase Agreement.

Notwithstanding anything herein to the contrary, the Company acknowledges that (a) Contractor is not a professional provider of the types of services included in the Services; (b) the personnel providing such Services may have other responsibilities to the business of Contractor and its Affiliates to which said personnel are required to devote substantial time that may take priority over the provision of Services from time to time, to the extent consistent with Contractor’s past practices in such regard; (c) such personnel will not be dedicated full-time to performing the Services; and (d) certain personnel of Contractor may leave the employment of Contractor or terminate their employment or contract with Contractor during the term of this Agreement; provided, however, that Contractor shall use its commercially reasonable efforts to mitigate any interruption in Services resulting from such departures and to resume as soon as reasonably practicable the Services in the manner agreed hereunder. The Company acknowledges that all Services to be provided under this Agreement shall be provided by Contractor to the extent that such Services do not unreasonably interfere with the ongoing business and operations of Contractor and its Affiliates, to the extent consistent with Contractor’s or such Affiliate’s past practices, and the loss of any Contractor’s personnel may materially impede Contractor’s ability to perform its obligations hereunder. Except as provided above, Contractor makes no representation or warranty regarding the ability of Contractor to retain any employees, contractors, or subcontractors and Contractor shall have no liability as to the result of the loss of any such employees, contractors, or subcontractors. Contractor shall not be responsible for the accuracy of any information filed with any governmental authority or furnished to the Company or to any of the Company’s employees for inclusion in any reports or for results obtained by use of any inaccurate information so filed or furnished, except, in each case, to the extent such information is provided or furnished by Contractor or one of its Affiliates.

4.    STANDARD OF PERFORMANCE. Subject to the terms of this Agreement, Contractor shall perform, or cause to be performed, the Services in a manner that is substantially similar in nature, timing and quality, and with the same degree of skill, prudence and care, as the actions comprising the Services were previously performed by Contractor in accordance with past practices prior to the Closing Date; provided, however, in no event shall Contractor have any obligations or liability hereunder except to the extent expressly set forth herein. Further, if the Company fails to consent to any reasonable request made by Contractor hereunder or fails to provide Contractor with any reasonably necessary information required by Contractor as contemplated in Section 3 above, Contractor shall be excused from the performance of, and shall bear no liability associated with, the Services that Contractor sought to perform in connection with such consent request or that are dependent upon the information requested.

The Initial Term and any Renewal Terms are collectively referred to herein as the “Term”.

For such time as any employees of or consultants or subcontractors to Contractor (or any subcontractor) are providing the Services to Company under this Agreement, (a) such employees or consultants will remain employees or consultants of Contractor (or any subcontractor), as applicable, and shall not be deemed to be employees of or consultants to the Company for any purpose, and (b) Contractor shall be solely responsible for the payment and provision of all compensation, wages, bonuses and commissions, employee benefits, including severance and worker’s compensation, and the withholding and payment of applicable taxes relating to such employment or engagement.
