ARTICLE II

LICENSE

Section 2.1 Grant of License. Upon the terms and conditions set forth in this Article II, Licensor hereby grants and conveys to Licensees a non-transferable, non-exclusive, royalty-free license to use the Marks in connection with the Licensees’ current and future businesses and the current and future services performed therewith during the term of this Agreement. Licensees shall not have the right to assign, transfer or sublicense any of the rights granted hereunder, except upon the written consent of the Licensor, which consent shall be given or withheld at the sole discretion of Licensor and which shall be limited by such conditions as Licensor may require at its sole discretion.

Section 2.2 Restrictions on Marks. In order to ensure the quality of the uses under the Marks, and to protect the goodwill of the Marks, Licensees agree as follows:

(a) Licensees will only use the Marks in formats approved by Licensor and only in strict association with Licensees’ businesses and the services performed therewith;

(b) Licensees will use the Marks only in accordance with such quality standards and specifications as may be established by Licensor and communicated to Licensees from time to time, it being understood that Licensor has evaluated Licensees’ businesses and services and determined that they are of a quality that justifies this grant of a license. Licensees recognize that through proper use of the Marks, goodwill will become associated with the Marks. Therefore, Licensees will maintain the quality of the businesses and services with respect to which Licensees use the Marks, and will not permit such quality to deteriorate so as to affect adversely the Marks and the goodwill that becomes associated therewith. If the quality of the businesses or services with respect to which Licensees use the Marks so deteriorates so as to affect adversely the goodwill associated with the Marks, Licensees shall at their expense immediately cease further use of the Marks and shall immediately cause the Marks to be removed from all materials associated with the businesses and services until rectified and from all marketing materials. Licensees shall promptly report to Licensor any material changes in the quality of the businesses or services with which Licensees use the Marks. Licensees will not take any action, or permit or fail to prevent any action by Licensees’ Affiliates or any other Person under Licensees’ control, that is deemed to injure, harm or dilute the distinctiveness or goodwill of the Marks;

(c) Prior to publishing any new format or appearance of the Marks or any new advertising or promotional materials that incorporate the Marks, Licensees shall first provide such format, appearance or materials to Licensor for its approval. If Licensor does not inform Licensees in writing within fourteen (14) days from the date of the receipt of such new format, appearance, or materials that such new format, appearance, or materials is or are unacceptable, then such new format, appearance or materials shall be deemed to be acceptable and approved by Licensor. Licensor may withhold approval of any new format or appearance of the Marks or materials incorporating the Marks which Licensees propose to use in Licensor’s sole discretion;

(d) Licensees shall not use any other trademarks, service marks, trade names or logos in connection with the Marks without prior written approval from Licensee during the term of this Agreement; and

(e) Licensees shall notify Licensor prior to using the Marks for any services for which the Marks are not currently registered at the U.S. Patent and Trademark Office. Licensees shall not use the Marks for any services for which the Marks are not currently registered without Licensor’s prior approval, which approval shall be given in Licensor’s sole discretion. If Licensor does not inform Licensees in writing within fourteen (14) days from the date of the receipt of such notice that such use of the Marks is unacceptable, then such use of the Marks shall be deemed to be acceptable and approved by Licensor.

Section 2.3 Ownership. Licensor owns and shall retain all right, title and interest in and to the Marks, including all goodwill relating thereto, and all trademark rights embodied therein are and shall at all times be solely vested in Licensor. Licensees have no right, title, interest or claim of ownership in the Marks, except for the licenses granted in this Agreement. All use of the Marks shall inure to the benefit of Licensor. Licensees agree that they will not attack, challenge or assist any third party in attacking or challenging the title of Licensor in and to the Marks. All rights not expressly granted by Licensor herein are reserved. No implied licenses are granted by Licensor pursuant to the terms of this Agreement. Licensees shall, if requested by Licensor at any time, at Licensor’s expense, execute such documents as reasonably requested by Licensor in order to confirm, consistent with the terms of this Agreement, the ownership or the licensing of such rights or to maintain the validity of the Marks or obtain or maintain registrations thereof for the goods or services applicable to the licensed uses herein.

Section 2.4 Protection of the Marks. Licensor shall have the exclusive right, but not the obligation, to protect the Marks (including monitoring potentially infringing uses, and initiating, prosecuting and defending litigation), and any rights therein and thereto, in its own name against all potential infringements and unauthorized uses of the Marks. Licensees shall provide any information and assistance reasonably requested by Licensor and/or join as a party in any such action at the reasonable request and at the sole cost and expense of Licensor. Licensor shall be entitled to all settlement amounts, damages or other monetary relief and costs and attorneys’ fees recovered in any such action, and Licensor shall have full discretion in determining whether, and upon what terms and conditions, to settle any such action. Licensees shall cooperate fully in the enforcement of rights in any infringement action brought against a third party or in the defense of any infringement or other action respecting the Marks brought or initiated by a third party. In the event Licensor determines, in its sole discretion, that it is not in the best interests of Licensor to initiate any legal proceedings on account of any such infringements, claims or actions, or in the event Licensor settles or resolves any such proceedings which may be initiated, Licensees shall have no claim against Licensor for damages or otherwise, nor shall the same affect the validity or enforceability of this Agreement. If Licensor elects not to initiate or pursue legal action in connection with a potential or actual infringement or unauthorized use of the Marks, upon prior written approval of Licensor, Licensees may take such legal action as they deem appropriate, and Licensor agrees to support such legal action at the cost and expense of Licensees. In such case, Licensees shall be entitled to all settlement amounts, damages or other monetary relief and costs and attorneys’ fees recovered in any such action.

Section 2.5 New Registration. Licensor shall have the sole right to seek additional registrations of the Marks in the U.S. Patent and Trademark Office or similar offices in different jurisdictions, whether for additional services or for additional formats and appearances of the Marks. Licensees shall not file for additional registrations unless requested to do so by Licensor. Licensees shall fully cooperate with Licensor’s efforts to seek additional registrations of the Marks and provide all reasonable assistance requested by Licensor, including executing any documents necessary for such registrations. Licensor shall own all rights, title and interest in and to such additional registrations.

Section 2.6 Confidentiality. Licensees shall maintain in strictest confidence all confidential or nonpublic information or material disclosed by Licensor and in the materials supplied hereunder in connection with the license of the Marks, whether in writing or orally and whether or not marked as confidential. Such confidential information includes, but is not limited to, algorithms, inventions, ideas, processes, computer system architecture and design, operator interfaces, operational systems, technical information, technical specifications, training and instruction manuals, and the like. In furtherance of the foregoing confidentiality obligation, Licensees shall limit disclosure of such confidential information to those of their employees, contractors or agents having a need to access the confidential information for the purpose of exercising rights granted hereunder.

Section 2.7 Estoppel. Nothing in this Agreement shall be construed as conferring by implication, estoppel, or otherwise upon Licensees (a) any license or other right under the intellectual property rights of Licensor other than the license granted herein with respect to the Marks as set forth expressly herein or (b) any license rights other than those expressly granted herein.

Section 2.8 Warranties; Disclaimers.

(a) Licensor represents and warrants that (i) Licensor owns, and Licensor has the right to license or sublicense, the Marks licensed under this Agreement and (ii) the Marks do not infringe upon the rights of any third parties.

(b) EXCEPT FOR THE WARRANTIES AND REPRESENTATIONS DESCRIBED IN SECTION 2.8(a), LICENSOR DISCLAIMS ANY AND ALL WARRANTIES, CONDITIONS OR REPRESENTATIONS (EXPRESS OR IMPLIED, ORAL OR WRITTEN) WITH RESPECT TO THE SUBJECT MATTER HEREOF, OR ANY PART THEREOF, INCLUDING ANY AND ALL IMPLIED WARRANTIES OF NON-INFRINGEMENT, MERCHANTABILITY OR FITNESS OR SUITABILITY FOR ANY PURPOSE (WHETHER ANY LICENSEE KNOWS, HAS REASON TO KNOW, HAS BEEN ADVISED, OR IS OTHERWISE IN FACT AWARE OF ANY SUCH PURPOSE) WHETHER ALLEGED TO ARISE BY LAW, BY REASON OF CUSTOM OR USAGE IN THE TRADE OR BY COURSE OF DEALING.

Section 2.9 In the Event of Termination. In the event of termination of this Agreement pursuant to Section 4.4 or otherwise, Licensees’ right to utilize or possess the Marks licensed under this Agreement shall automatically cease, and no later than ninety (90) days following such termination, (a) the Licensees shall cease all use of the Marks and shall adopt

trademarks, service marks, and trade names that are not confusingly similar to the Marks, (b) at Licensor’s request, the Licensees shall destroy all materials and content upon which the Marks continue to appear (or otherwise modify such materials and content such that the use or appearance of the Marks ceases) that are under Licensees’ control, and certify in writing to Licensor that Licensees have done so, and (c) each of the Licensees shall change its legal name so that there is no reference therein to the name “Rose Rock,” “SemCrude,” any name or d/b/a then used by any SemGroup Entity or any variation, derivation or abbreviation thereof, and in connection therewith, shall make all necessary filings of certificates with the Secretary of State of the State of Delaware and to otherwise amend its Organizational Documents by such date.

(a) any failure of the Partnership Group to be the owner on the Closing Date of valid and indefeasible easement rights, rights-of-way, leasehold and/or fee ownership interests in and to the lands on which any Partnership Assets are located to the extent that such failure renders the Partnership Group liable to a third party or unable to use or operate the Partnership Assets in substantially the same manner as they were used or operated by SemCrude, L.P. or any SemGroup Entity immediately prior to the Closing Date;

(d) any of the matters identified on Schedule 3.2(d) hereto or any claims made before, on or after the Closing Date relating to the bankruptcy and reorganization of SemGroup and certain of its subsidiaries under Chapter 11 of the U.S. Bankruptcy Code;

Section 3.3 Indemnification by the Partnership Group. Subject to the provisions of Section 3.4 and Section 3.5, the Partnership Group shall indemnify, defend and hold harmless the SemGroup Entities from and against any Losses (including Covered Environmental Losses) suffered or incurred by the SemGroup Entities and related to or arising out of or in connection with the ownership or operation of the Partnership Assets after the Closing Date, except to the extent that any member of the Partnership Group is entitled to indemnification hereunder or unless such indemnification would not be permitted under the Partnership Agreement.

(b) The aggregate liability of SemGroup under Section 3.1(a) and Section 3.2(e) shall not exceed $20 million.

(c) No claims may be made against SemGroup for indemnification pursuant to Section 3.1(a) or Section 3.2 unless the aggregate dollar amount of the Losses suffered or incurred by the Partnership Group exceeds $500,000, after which SemGroup shall be liable for the full amount of such claims in excess of $500,000, subject to the limitations of Section 3.4(a).

(d) In no event shall SemGroup be obligated to the Partnership Group under Section 3.1(a) or Section 3.2 for any Losses or income tax liabilities to the extent such Losses or liabilities reserved for in the Partnership Group’s financial statements as of the Closing Date.

Section 3.5 Indemnification Procedures.

(a) The Indemnified Party agrees that promptly after it becomes aware of facts giving rise to a claim for indemnification under this Article III, it will provide notice thereof in writing to the Indemnifying Party, specifying the nature of and specific basis for such claim; provided, however, that the Indemnified Party shall not submit claims more frequently than once a calendar quarter (or twice in the case of the calendar quarter in which the applicable indemnity coverage under this Agreement expires) unless such Indemnified Party believes in good faith that such a delay in notice to the Indemnifying Party would cause actual prejudice to the Indemnifying Party’s ability to defend against the applicable claim. Notwithstanding anything in this Article III to the contrary, a delay by the Indemnified Party in notifying the Indemnifying Party shall not relieve the Indemnifying Party of its obligations under this Article III, except to the extent that such failure shall have caused actual prejudice to the Indemnifying Party’s ability to defend against the applicable claim.

(b) The Indemnifying Party shall have the right to control all aspects of the defense of (and any counterclaims with respect to) any claims brought against the Indemnified Party that are covered by the indemnification under this Article III, including, without limitation, the selection of counsel, the determination of whether to appeal any decision of any court and the settlement of any such matter or any issues relating thereto; provided, however, that no such settlement shall be entered into without the consent of the Indemnified Party (with the concurrence of the Conflicts Committee in the case of the Partnership Group) unless it includes a full release of the Indemnified Party from such matter or issues, as the case may be, and does not include any admission of fault, culpability or a failure to act, by or on behalf of such Indemnified Party.

(c) The Indemnified Party agrees to cooperate fully with the Indemnifying Party with respect to all aspects of the defense of any claims covered by the indemnification under this Article III, including, without limitation, the prompt furnishing to the Indemnifying Party of any correspondence or other notice relating thereto that the Indemnified Party may receive, permitting the name of the Indemnified Party to be utilized in connection with such defense, the making available to the Indemnifying Party of any files, records or other information of the Indemnified Party that the Indemnifying Party considers relevant to such defense and the making available to the Indemnifying Party, at no cost to the Indemnifying Party, of any employees of the Indemnified Party; provided, however, that in connection therewith the Indemnifying Party agrees to use reasonable efforts to minimize the impact thereof on the operations of the Indemnified Party and further agrees to maintain the confidentiality of all files, records and other information furnished by the Indemnified Party pursuant to this Section 3.5. In no event shall the obligation of the Indemnified Party to cooperate with the Indemnifying Party as set forth in the

immediately preceding sentence be construed as imposing upon the Indemnified Party an obligation to hire and pay for counsel in connection with the defense of any claims covered by the indemnification set forth in this Article III; provided, however, that the Indemnified Party may, at its own option, cost and expense, hire and pay for counsel in connection with any such defense. The Indemnifying Party agrees to keep any such counsel hired by the Indemnified Party informed as to the status of any such defense, but the Indemnifying Party shall have the right to retain sole control over such defense.

(d) In determining the amount of any Losses for which the Indemnified Party is entitled to indemnification under this Agreement, the gross amount of the indemnification will be reduced by (i) any insurance proceeds realized by the Indemnified Party and (ii) all amounts recovered by the Indemnified Party under contractual indemnities from third Persons. The Indemnified Party shall use commercially reasonable efforts to realize any applicable insurance proceeds or amounts recoverable under such contractual indemnities.

(e) The date on which the Indemnifying Party receives notification of a claim for indemnification shall determine whether such claim is timely made.

(f) NOTWITHSTANDING ANYTHING HEREIN TO THE CONTRARY, IN NO EVENT SHALL ANY PARTY’S INDEMNIFICATION OBLIGATION HEREUNDER COVER OR INCLUDE CONSEQUENTIAL, INDIRECT, INCIDENTAL, PUNITIVE, EXEMPLARY, SPECIAL OR SIMILAR DAMAGES OR LOST PROFITS SUFFERED BY ANY OTHER PARTY ENTITLED TO INDEMNIFICATION UNDER THIS AGREEMENT.

No consent or waiver, express or implied, by any Party to or of any breach or default by any other Party in the performance by such other party of its obligations hereunder shall be deemed or construed to be a consent or waiver to or of any other breach or default in the performance by such other Party of the same or any other obligations of such other Party hereunder. Failure on the part of a Party to complain of any act of any other Party or to declare any other Party in default, irrespective of how long such failure continues, shall not constitute a waiver by such Party of its rights hereunder until the applicable statute of limitations period has run.

Section 4.6 Amendment or Modification. This Agreement may be amended or modified from time to time only by the written agreement of all the Parties; provided, however, that the Partnership may not, without the prior approval of the Conflicts Committee, agree to any amendment or modification of this Agreement that the General Partner determines will adversely affect the holders of Common Units.

Section 4.7 Assignment; Third Party Beneficiaries. No Party may assign its rights or obligations under this Agreement without the consent of the other Parties. Each of the Parties hereto specifically intends that each SemGroup Entity and each member of the Partnership

Group, as applicable, whether or not a Party to this Agreement, shall be entitled to assert rights and remedies hereunder as third-party beneficiaries hereto with respect to those provisions of this Agreement affording a right, benefit or privilege to a Party that is a SemGroup Entity or member of the Partnership Group, respectively.

Section 4.8 Counterparts. This Agreement may be executed in any number of counterparts, each of which shall be deemed an original, with the same effect as if all signatory Parties had signed the same document. All counterparts shall be construed together and shall constitute one and the same instrument.

Section 4.9 Severability. If any provision of this Agreement or the application thereof to any Person or circumstance shall be held invalid or unenforceable to any extent, the remainder of this Agreement and the application of such provision to other Persons or circumstances shall not be affected thereby and shall be enforced to the greatest extent permitted by law.

Section 4.10 Gender, Parts, Articles and Sections. Whenever the context requires, the gender of all words used in this Agreement shall include the masculine, feminine and neuter, and the number of all words shall include the singular and plural. All references to Article numbers and Section numbers refer to Articles and Sections of this Agreement.

Section 4.12 Withholding or Granting of Consent. Except as otherwise expressly provided in this Agreement, each Party may, with respect to any consent or approval that it is entitled to grant pursuant to this Agreement, grant or withhold such consent or approval in its sole and uncontrolled discretion, for any reason, and subject to such conditions as it shall deem appropriate.

Section 4.13 Laws and Regulations. Notwithstanding any provision of this Agreement to the contrary, no Party shall be required to take any act, or fail to take any act, under this Agreement if the effect thereof would be to cause such Party to be in violation of any applicable law, statute, rule or regulation.

Section 4.14 Negation of Rights of Limited Partners, Assignees and Third Parties. Except as provided in Section 4.7, the provisions of this Agreement are enforceable solely by the Parties, and no shareholder, limited partner, member, or assignee of SemGroup, the General Partner or the Partnership or other Person shall have the right, separate and apart from SemGroup, the General Partner or the Partnership, to enforce any provision of this Agreement or to compel any Party to comply with the terms of this Agreement.
