This opinion is being furnished in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act.

In our examination, we have assumed the genuineness of all signatures, including electronic signatures, the legal capacity and competency 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 facsimile, electronic, certified or photocopied copies, and the authenticity of the originals of such copies. In making our examination of executed documents, we have assumed that the parties thereto, other than the Company, had the power, corporate or other, to enter into and perform all obligations thereunder and have also assumed the due authorization by all requisite action, corporate or other, and the execution and delivery by such parties of such documents and the validity and binding effect thereof on such parties. As to any facts relevant to the opinion stated herein that we did not independently establish or verify, we have relied upon statements and representations of officers and other representatives of the Company and others and of public officials, including the facts and conclusions set forth in the Secretary’s Certificate.

We do not express any opinion with respect to the laws of any jurisdiction other than the General Corporation Law of the State of Delaware (the “DGCL”).

Based upon the foregoing and subject to the qualifications and assumptions stated herein, we are of the opinion that the Shares have been duly authorized by all requisite corporate action on the part of the Company under the DGCL and, when awarded by the Board of Directors of the Company or a duly authorized committee thereof and issued and paid for in accordance with the terms of the applicable Plan and the applicable award agreements under the applicable Plan, the Shares will be validly issued, fully paid and nonassessable.

In rendering the opinion stated herein, we have assumed that (i) an appropriate account statement evidencing the Shares credited to a recipient’s account maintained with the Company’s transfer agent has been or will be issued by the Company’s transfer agent; (ii) the issuance of the Shares will be properly recorded in the books and records of the Company; (iii) each award agreement pursuant to which rights to acquire Evergreen Shares or other awards are granted pursuant to the 2021 Plan will be consistent with the 2021 Plan and will be duly authorized, executed and delivered by the parties thereto; (iv) the consideration received by the Company for each of the Shares delivered pursuant to the Plans shall not be less than the $0.0001 per share; and (v) the issuance of the Shares does not violate or conflict with any agreement or instrument binding on the Company (except that we do not make this assumption with respect to the Company’s Amended and Restated Certificate of Incorporation or the Amended and Restated Bylaws).
