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.

13. Certificates. Ownership will be maintained in an ownership ledger kept in electronic format and no certificates will be issued unless specifically requested by a member.

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.
