The sales and issuances of the Shares authorized by the Amendment to Sale Agreement will be made pursuant to the Company's effective shelf registration statement on Form S-3ASR (File No.333-278770) (the "Registration Statement"), that was automatically effective upon filing with the SEC on April 17, 2024, as supplemented by the Prospectus Supplement.

The offering and sale of the Shares are being made pursuant to the Open Market Sale Agreement dated April 30, 2021, as amended by that certain Amendment No. 1 to Open Market Sale Agreement dated December 23, 2025 (the "***Sale Agreement***"), by and between the Company and Jefferies LLC.

We have examined copies of the Sale Agreement, the Registration Statement, the base prospectus that forms a part thereof (the "***Base Prospectus***") as supplemented by the prospectus supplement dated on or about the date hereof, in the form filed with the Commission pursuant to Rule 424(b) of the Rules and Regulations, together with the documents or portions thereof incorporated by reference therein, as modified or superseded as described therein (the "***Prospectus Supplement***" and, together with the Base Prospectus, the "***Prospectus***").

In such examination, we have assumed (i) the authenticity of original documents and the genuineness of all signatures, (ii) the conformity to the originals of all documents submitted to us as copies, and (iii) the truth, accuracy, and completeness of the information, representations and warranties contained in the records, documents, instruments and certificates we have reviewed.

Based upon and subject to the foregoing qualifications, assumptions and limitations, we are of the opinion that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. The Shares have been duly authorized by the Company and, when issued and delivered by the Company against
payment therefor in accordance with the terms of and in the manner contemplated by the Sale Agreement, will be validly issued, fully paid and nonassessable.
