(d) an executed copy of a certificate of Stephen W. Ries, Secretary of the Company, dated the date hereof (the “Secretary’s Certificate”);

(e) a copy of the Company’s Certificate of Formation certified by the Secretary of State of the State of Delaware as of August 24, 2020, and certified pursuant to the Secretary’s Certificate;

(f) a copy of the Company’s Amended and Restated Limited Liability Company Agreement, dated as of June 16, 2020, as amended and in effect as of August 25, 2020 and certified pursuant to the Secretary’s Certificate;

(g) a copy of the Company’s Second Amended and Restated Limited Liability Company Agreement, dated as of August 28, 2020, as amended and in effect as of the date hereof and certified pursuant to the Secretary’s Certificate (the “Second Amended and Restated LLC Agreement” and, together with the Certificate of Formation, the “Organizational Documents”);

We have also examined originals or copies, certified or otherwise identified to our satisfaction, of such records of the Company and such agreements, certificates and receipts of public officials, certificates of officers or other representatives of the Company and others, and such other documents as we have deemed necessary or appropriate as a basis for the opinions stated below, including the facts and conclusions set forth in the Secretary’s Certificate.

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.

limited liability company or other, to enter into and perform all obligations thereunder, and we also have assumed the due authorization by all requisite action, limited liability company or other, and the execution and delivery by such parties of such documents and the validity and binding effect thereof on such parties. We have also assumed that the Second Amended and Restated LLC Agreement is the only limited liability company agreement, as defined under the Delaware Limited Liability Company Act (the “DLLCA”), of the Company, and that the Company has, and since the time of its formation has had, at least one validly admitted and existing member of the Company and (i) no procedures have been instituted for, and no other event has occurred, including, without limitation, any action taken by the Company or the Board of Directors or members, that would result in the liquidation, dissolution or winding-up of the Company, (ii) no event has occurred that has adversely affected the good standing of the Company under the laws of its jurisdiction of formation, and the Company has taken all actions required by the laws of its jurisdiction of formation to maintain such good standing, and (iii) no grounds exist for the revocation or forfeiture of the Second Amended and Restated Certificate of Formation. Further, we have assumed that, at the time of issuance and delivery of the Shares, (i) each agreement setting forth the terms of each grant under the Plan will be consistent with the Plan and will be duly authorized and validly executed and delivered by the parties thereto, (ii) the Board of Directors of the Company, including any duly authorized committee thereof, shall have taken all necessary limited liability company action to approve the issuance such Class A Common Shares and related matters and appropriate officers of the Company, as applicable, have taken all related action as directed by or under the direction of the Board of Directors, and (iii) the issuance of the Class A Common 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 Organizational Documents). As to any facts relevant to the opinions 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 DLLCA.

Based upon the foregoing and subject to the qualifications and assumptions stated herein, we are of the opinion that the Class A Common Shares when issued to the participants in accordance with the terms and conditions of the Certificate of Formation, the Plan and the applicable award agreement for consideration paid or delivered in an amount at least equal to the par value of such Class A Common Shares, the Class A Common Shares will be validly issued, fully paid and under the DLLCA, the holders of the Class A Common Shares will have no obligation to make further payments for the purchase of such Class A Common Shares or contributions to the Company solely by reason of their ownership of such Class A Common Shares except for their obligation to repay any funds wrongfully distributed to them.

We hereby consent to the reference to our firm under the heading “Legal Matters” in the prospectus forming part of the Registration Statement. We also hereby consent to the filing of this opinion with the Commission as an exhibit to the Registration Statement. In giving this
