Re: Beneficient Registration Statement on Form S-1

Ladies and Gentlemen:

We have acted as counsel to Beneficient, a Nevada corporation (the “Company”), in connection with the preparation and filing with the Securities and Exchange Commission (the “Commission”) under the Securities Act of 1933, as amended (the “Securities Act”), of a registration statement on Form S-1, initially filed by the Company on October 26, 2023 (as thereafter amended or supplemented, the “Registration Statement”).

The Registration Statement relates to the registration of (i) the offer and sale from time to time by the Selling Holders (as defined in the Registration Statement) of up to (a) 17,901,459 shares of our Class A common stock, par value $0.001 (“Class A common stock” and such shares, the (“Initial Shares”)), (b) 942,249 warrants, with each warrant exercisable for one share of Class A common stock and one share of Series A convertible preferred stock, par value $0.001 (the “Series A preferred stock”), at an exercise price of $11.50 (the “Warrants”), (c) 942,249 shares of Class A common stock and 942,249 shares of Series A preferred stock issuable upon the exercise of the Warrants (the “Resale Warrant Shares”), and (d) 235,562 shares of Class A common stock underlying 942,249 shares of Series A preferred stock (the “Resale Conversion Shares”) and (ii) the issuance by us to persons other than the current holder of the Warrants of (a) up to 942,249 shares of our Class A common stock and 942,249 shares of Series A preferred stock upon exercise of the Warrants (the “Primary Warrant Shares”) and (b) 235,562 shares of Class A common stock that may be issued upon conversion of the 942,249 shares of Series A preferred stock underlying such Warrants (the “Primary Conversion Shares” and together with the Initial Shares, the Resale Warrant Shares, the Resale Conversion Shares and the Primary Warrant Shares, the “Offered Securities”).

In rendering the opinion set forth herein, we have examined the originals, or photostatic or certified copies, of (i) the Articles of Incorporation and Bylaws of the Company; (ii) certain resolutions of the Board of Directors of the Company related to the filing of the Registration Statement, the authorization and issuance of the Offered Securities and related matters; (iii) the Registration Statement and all exhibits included or incorporated by reference thereto; (iv) a certificate executed by an officer of the Company, dated as of the date hereof; (v) a copy of that certain Warrant Agreement, dated October 5, 2021, between Continental Stock Transfer & Trust Company (“Continental”) and Avalon Acquisition Inc., as amended, (vi) a copy of that certain Assignment, Assumption and Amendment to Warrant Agreement by and among the Company, Avalon and Continental, dated June 7, 2023, (vii) the Certificate of Designation for the Series A preferred stock (the “Series A Certificate of Designation”), (viii) the Certificate of Designation for the Series B-1 resettable convertible preferred stock, par value $0.001 per share (the “Series B-1 preferred stock”), (ix) that certain notice of conversion for the Series B-1 preferred stock delivered by The GRID Holding Co. LLC to the Company on September 29, 2023 and (x) such other records, documents and instruments as we deemed relevant and necessary for purposes of the opinion stated herein.

In making the foregoing examination, we have assumed the genuineness of all signatures, the legal capacity of all natural persons, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as photostatic or certified copies, and the authenticity of the originals of such copies. As to all questions of fact material to this opinion, where such facts have not been independently established, we have relied, to the extent we have deemed reasonably appropriate, upon representations or certificates of officers of the Company or governmental officials.
