For purposes of the opinion set forth below, we have reviewed and relied upon the Merger Agreement, the Joint Proxy Statement of PCSC and the Company (the “Proxy Statement”) included in the Registration Statement on Form S-4 filed by PCSC with the Securities and Exchange Commission (“SEC”) in connection with the issuance of shares of PCSC Shares in connection with the Mergers (the “Merger Registration Statement”), and such other documents, records and instruments as we have deemed necessary or appropriate as a basis for our opinion. In addition, in rendering our opinion we have relied upon certain statements, representations and warranties made by PCSC, Merger Sub I, Merger Sub II and the Company in (i) representation letters provided to us in connection with our preparation of this opinion, (ii) the Proxy Statement, and (iii) the Merger Agreement, which we have neither investigated nor verified. We have assumed that such statements, representations and warranties are true, correct, complete and not breached and will continue to be so through the date of the Mergers, that no actions that are inconsistent with such statements, representations and warranties will be taken, and that all representations, statements, and warranties made “to the best knowledge of” any person(s) or party(ies) or with similar qualification are and will be true, correct and complete as if made without such qualification.

We also have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to the original documents of all documents submitted to us as copies, the authority and capacity of the individual or individuals who executed any such documents on behalf of any person, the conformity to the final documents of all documents submitted to us as drafts and the accuracy and completeness of all records made available to us. In addition, we have assumed that the Mergers will be consummated in accordance with the Merger Agreement, that each of the parties to the Merger Agreement will comply with all reporting obligations with respect to the Mergers required under the Code and the Treasury Regulations thereunder, and that the Merger Agreement is valid and binding in accordance with its terms.

Any inaccuracy in, or breach of, any of the aforementioned statements, representations, warranties and assumptions or any change after the date hereof in applicable law could adversely affect our opinion. No ruling has been or will be sought from the Internal Revenue Service by any party to the Merger Agreement as to the United States federal income tax consequences of any aspect of the Mergers.

Based upon and subject to the foregoing, as well as the limitations set forth below, it is our opinion, under currently applicable United States federal income tax law, that the Mergers, taken together, should constitute a reorganization within the meaning of Section 368(a) of the Code.
