V. OPINIONS

Based upon and subject to the foregoing, and subject further to the qualifications, exceptions, and limitations set forth in Section VI below, we are of the opinion that:

Opinion 1: Valid Existence and Good Standing — Parent

Solara Digital Infrastructure Fund VI LP has been duly formed and is a limited partnership validly existing and in good standing under the laws of the State of Delaware. In rendering this opinion, we have relied upon our review of the Certificate of Limited Partnership of Parent, as filed with the Secretary of State of the State of Delaware, the Partnership Agreement, and the Certificate of Good Standing for Parent issued by the Secretary of State of the State of Delaware, dated July 3, 2024. Solara Fund VI GP LLC is a limited liability company duly formed and validly existing under the laws of the State of Delaware and is the sole general partner of Parent.

Opinion 2: Valid Existence and Good Standing — Merger Sub

Stratos Merger Sub Inc. has been duly incorporated and is a corporation validly existing and in good standing under the laws of the State of Delaware. In rendering this opinion, we have relied upon our review of the Certificate of Incorporation of Merger Sub, as filed with the Secretary of State of the State of Delaware on January 8, 2024 (DE File No. 7923841), the Bylaws of Merger Sub, and the Certificate of Good Standing for Merger Sub issued by the Secretary of State of the State of Delaware, dated July 3, 2024.

Merger Sub was formed solely for the purpose of effectuating the reverse triangular merger contemplated by the Merger Agreement, pursuant to which Merger Sub will merge with and into the Company, with the Company continuing as the surviving entity. Merger Sub has not conducted any business, incurred any obligations, or acquired any assets or liabilities other than those incident to its formation, the negotiation and execution of the Merger Agreement, and the transactions contemplated thereby. Solara Digital Infrastructure Fund VI LP is the sole stockholder of Merger Sub, holding all of the issued and outstanding shares of capital stock of Merger Sub.

Opinion 3: Power and Authority — Parent

Parent has all requisite limited partnership power and authority under the DRULPA and its Partnership Agreement to execute, deliver, and perform its obligations under each Transaction Document to which it is a party, including, without limitation, the Merger Agreement, the Equity Commitment Letter, and the Limited Guarantee (to the extent Parent is a party thereto or bound thereby), and to consummate the transactions contemplated by the Transaction Documents. Solara Fund VI GP LLC, as the sole general partner of Parent, has all requisite limited liability company power and authority under the Delaware Limited Liability Company Act, the GP LLC Agreement, and the Partnership Agreement to act on behalf of Parent in connection with the execution, delivery, and performance of the Transaction Documents and the consummation of the transactions contemplated thereby.

Merger Sub has all requisite corporate power and authority to merge with and into the Company pursuant to the terms of the Merger Agreement and the Certificate of Merger, with the Company surviving the Merger as a wholly owned subsidiary of Parent.

Opinion 5: Due Authorization — Parent

The execution, delivery, and performance by Parent of each Transaction Document to which it is a party, and the consummation by Parent of the transactions contemplated thereby, have been duly authorized by all necessary limited partnership action on the part of Parent. In rendering this opinion, we have reviewed the GP Resolutions, dated January 22, 2024, pursuant to which Solara Fund VI GP LLC (acting in its capacity as general partner of Parent) duly authorized the execution, delivery, and performance by Parent of the Merger Agreement, the Equity Commitment Letter (in the amount of $2,832,888,096), the Limited Guarantee (in the amount of $246,000,000), and all related transaction documents, and approved the consummation of the transactions contemplated thereby. Under the Partnership Agreement and the DRULPA, no other limited partnership action, vote, consent, or approval on the part of Parent, its general partner, or any of its limited partners is required in connection with the Transaction Documents or the transactions contemplated thereby.

Opinion 6: Due Authorization — Merger Sub

The execution, delivery, and performance by Merger Sub of the Merger Agreement, and the consummation by Merger Sub of the Merger, have been duly authorized by all necessary corporate action on the part of Merger Sub. In rendering this opinion, we have reviewed:

(a) the Board Consent, being the Unanimous Written Consent of the sole director of Stratos Merger Sub Inc., dated January 22, 2024, pursuant to which the sole director of Merger Sub approved and adopted the Merger Agreement, approved the Merger and the other transactions contemplated by the Merger Agreement, and recommended the approval and adoption of the Merger Agreement by the sole stockholder of Merger Sub; and

(b) the Stockholder Consent, being the Written Consent of Solara Digital Infrastructure Fund VI LP, as the sole stockholder of Stratos Merger Sub Inc., dated January 22, 2024, pursuant to which Parent, as the sole stockholder of Merger Sub, approved and adopted the Merger Agreement and approved the consummation of the Merger.

Under the DGCL, the Certificate of Incorporation, and the Bylaws of Merger Sub, no other corporate action, vote, consent, or approval on the part of Merger Sub, its board of directors, or its stockholders is required in connection with the Merger Agreement or the consummation of the Merger.

Opinion 7: Due Execution and Delivery

Each Transaction Document to which Parent is a party has been duly executed and delivered by Parent. The Merger Agreement has been duly executed and delivered by Merger Sub. In rendering this opinion, we have relied upon our review of the execution versions of the Transaction Documents, the incumbency certificates delivered at closing on July 9, 2024, and the Secretary's Certificates of Parent and Merger Sub, each of which confirms the identity and authority of the persons who executed the Transaction Documents on behalf of Parent and Merger Sub, respectively.

Opinion 8: Enforceability

The Merger Agreement constitutes the legal, valid, and binding obligation of each of Parent and Merger Sub, enforceable against each of Parent and Merger Sub in accordance with its terms. The Equity Commitment Letter constitutes the legal, valid, and binding obligation of Parent, enforceable against Parent in accordance with its terms. The Limited Guarantee constitutes the legal, valid, and binding obligation of Solara Fund VI GP LLC (as guarantor), enforceable against Solara Fund VI GP LLC in accordance with its terms.

The foregoing enforceability opinions are subject to and limited by the Enforceability Exceptions set forth in Section VI.A below.

Opinion 9: No Violation — Organizational Documents

Neither the execution, delivery, nor performance by Parent of any Transaction Document to which it is a party, nor the consummation by Parent of the transactions contemplated thereby (including the Merger), conflicts with, results in a violation or breach of, constitutes a default under (with or without notice or lapse of time, or both), or results in the acceleration of any obligation under, or requires any consent or approval under, any provision of:

(a) the Certificate of Limited Partnership or the Partnership Agreement of Parent; or

(b) the Certificate of Formation or the GP LLC Agreement of Solara Fund VI GP LLC.

Neither the execution, delivery, nor performance by Merger Sub of the Merger Agreement, nor the consummation by Merger Sub of the Merger, conflicts with, results in a violation or breach of, constitutes a default under (with or without notice or lapse of time, or both), or results in the acceleration of any obligation under, or requires any consent or approval under, any provision of:

(d) the Bylaws of Merger Sub.

Opinion 10: No Violation — Delaware Law

Neither the execution, delivery, nor performance by Parent or Merger Sub of the Transaction Documents to which either is a party, nor the consummation of the Merger, violates any applicable provision of the DGCL or the DRULPA. This opinion is limited to the statutory provisions of the DGCL and the DRULPA as currently in effect on the date hereof and does not extend to any provision of federal law, the laws of England and Wales, or the laws of any jurisdiction other than the State of Delaware.

Opinion 12: Certificate of Merger
