Until such time as this Agreement is terminated as provided in Section 5.4, the Partnership hereby agrees to provide the ETRN Entities with access to, and use of, the Subject Assets for purposes of providing G&A Services to the ETRN Entities due to the fact that the ETRN Entities do not otherwise own similar assets.

4.2    Ownership and Quality.

(a)    ETRN agrees that ownership of the Name and the Marks and the goodwill relating thereto shall remain vested in the Partnership, the owner of the mark, and any successor thereto, both during the term of this License and thereafter, and ETRN further agrees, and agrees to cause the ETRN Entities and Partnership Entities never to challenge, contest or question the validity of the Partnership’s ownership of the Name and Marks or any registration thereto by the Partnership. In connection with the use of the Name and the Marks, each ETRN Entity and each Partnership Entity (other than the Partnership) shall not in any manner represent that they have any ownership interest in the Name and the Marks or registration thereof except as set forth herein, and ETRN, on behalf of itself and the ETRN Entities and Partnership Entities, acknowledges that the use of the Name and the Marks shall not create any right, title or interest in or to the Name and the Marks, and all use of the Name and the Marks by an ETRN Entity or a Partnership Entity shall inure to the benefit of the Partnership.

(b)    ETRN agrees, and agrees to cause each ETRN Entity and Partnership Entity, to use the Name and Marks in accordance with such quality standards established by or for the Partnership and communicated to ETRN from time to time, it being understood that the products and services offered by the ETRN Entities and the Partnership Entities immediately before the Closing Date are of a quality that is acceptable to the Partnership and justifies the License. In the event any ETRN Entity or Partnership Entity is determined by the Partnership to be using the Marks in a manner not in accordance with quality standards established by the Partnership, the Partnership shall provide written notice of such unacceptable use including the reason why applicable quality standards are not being met. If acceptable proof that quality standards are met is not provided to the Partnership within thirty (30) days of such notice, the entity’s license to use the Marks shall terminate and shall not be renewed absent written authorization from the Partnership.

4.3    In the Event of Termination. In the event of termination of this Agreement, pursuant to Section 5.4 or otherwise, or the termination of the License, the right of the ETRN Entities and the Partnership Entities (other than the Partnership) to utilize or possess the Marks licensed under this Agreement shall automatically cease, and no later than ninety (90) days following such termination, (a) each ETRN Entity and, at the Partnership’s request, each Partnership Entity (other than the Partnership) shall cease all use of the Marks and shall adopt trademarks, service marks, and trade names that are not confusingly similar to the Marks, provided, however, that any use of the Marks during such 90-day period shall continue to be subject to Section 4.2(b), (b) at the Partnership’s request, the ETRN Entities and the Partnership Entities (other than the Partnership) 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 their control, and certify in writing to the Partnership that the ETRN Entities and the Partnership Entities have done so, and (c) each ETRN Entity and, at the Partnership’s request, each Partnership Entity shall change its legal name so that there is no reference therein to the name “Equitrans,” any name or d/b/a then used by the Partnership 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.
