party to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of the Company) by reason of the fact that such person is or was a member,
Manager, officer, employee or agent of the Company, or is or was serving at the request of the Company as a director, manager, officer, employee or agent of another corporation, partnership, joint venture, trust, limited liability company or other
enterprise, against expenses, including attorneys’ fees, judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding if such person acted in good faith and
in a manner such person reasonably believed to be in or not opposed to the best interests of the Company, and, with respect to any criminal action or proceeding, had no reasonable cause to believe the conduct was unlawful. The termination of any
action, suit or proceeding by judgment, order, settlement, conviction or upon a plea of nolo contendere or its equivalent, will not, of itself, create a presumption that such person did not act in good faith and in a manner which such person
reasonably believed to be in or not opposed to the best interests of the Company, and, with respect to any criminal action or proceeding, had reasonable cause to believe that the conduct was unlawful.

certificate, bear the seal of the Company and be issued according to the numerical order maintained in the electronic ownership ledger. A record of each certificate issued will be maintained by the Company. Any or all the signatures on the
certificate may be a facsimile. In case any officer, transfer agent or registrar who has signed or whose facsimile signature has been placed upon a certificate will have ceased to be such officer, transfer agent or registrar before such certificate
is issued, it may be issued by the Company with the same effect as if the person who signed the certificate was such officer, transfer agent or registrar at the date of issue. 

14. Transfer. The secretary will transfer units on the books of the Company on receipt of proper evidence of succession, assignment or authority to
transfer and evidence of compliance with any agreement restricting transfer by which the member is bound, or if a unit certificate has been previously issued, the surrender of the certificate or certificates representing the transferred units duly
endorsed or accompanied by the foregoing proper evidence. Surrendered certificates will be canceled and, if requested, new certificates issued to the member entitled thereto. 
  

	15.	Miscellaneous. It is further agreed that: 

  

	 	15.1.	Amendment. Any amendment of this Agreement or the Articles will require the written approval of the Member. 

  

	 	15.2.	Governing Law. This Agreement has been executed, delivered and is intended to be performed in Oklahoma City, Oklahoma, and the substantive laws of the State of Oklahoma will govern the validity, construction and
enforcement of this Agreement. 

  

	 	15.3.	Binding Effect. This instrument may not be changed, modified, amended or supplemented except in writing. This Agreement will be binding on the Member and the Member’s representatives, successors and assigns.
If any part of this Agreement is held to be unenforceable, the balance will nevertheless be carried into effect. 

  

	 	15.4.	Notices. Any notice, payment, demand or communication required or permitted to be given by any provision of this Agreement will be deemed to have been given when delivered personally to the Member or Manager or
when actually received if sent by registered or certified mail, postage and charges prepaid, to the Member or Manager at the address reflected on the Company’s books and records.
