This opinion letter is based as to matters of law solely on the applicable provisions of the laws of the State of Georgia, the State of Kansas and the State of Nevada (but not including any laws, statutes, ordinances, administrative decisions, rules or regulations of any political subdivision below the state level), as currently in effect. We express no opinion herein as to any other statutes, rules or regulations (and in particular, we express no opinion as to any effect that such other statutes, rules or regulations may have on the opinions expressed herein).

Based upon, subject to and limited by the foregoing, we are of the opinion that:

1.          Each Opinion Guarantor is validly existing as a corporation or limited liability company, as applicable, under the laws of its Opinion Jurisdiction.

2.          Each Opinion Guarantor has the corporate or limited liability company power, as applicable, under the laws of its Opinion Jurisdiction to issue the Primary Guarantees.

3.          The Existing Guarantees have been duly authorized by each Opinion Guarantor.

This opinion letter has been prepared for use in connection with the 2023 Amendment.  Please note that we are opining only as to matters set forth herein, and no opinion should be inferred as to any other matters.  This opinion letter is given only as of the time of its delivery, and we assume no obligation or responsibility to update or supplement this opinion letter after its delivery.
