For purposes of rendering our opinion, we have assumed that (i) the Merger will be consummated in the manner described in the Merger Agreement and the Registration Statement, (ii) the statements concerning the Merger set forth in the Merger Agreement and the Registration Statement are true, complete and correct and will remain true, complete and correct at all times up to and including the Effective Time, (iii) the factual statements and representations made by Floridian and SBC in their respective Representation Letters dated as of the date hereof and delivered to us for purposes of this opinion are true, complete and correct as of the date hereof and will remain true, complete and correct at all times up to and including the Effective Time, and (iv) any representations made in the Merger Agreement or the Representation Letters “to the knowledge of”, or based on the belief of Floridian or SBC or similarly qualified, are true, complete and correct and will remain true, complete and correct at all times up to and including the Effective Time, in each case without such qualification. We have also assumed that the parties have complied with and, if applicable, will continue to comply with, the obligations, covenants, and agreements contained in the Merger Agreement.

Our opinion is based upon the Internal Revenue Code of 1986, as amended (the “Code”), applicable Treasury regulations, rulings and decisions thereunder, and such other authorities as we have considered relevant, each as in effect on the date hereof, and may be affected by amendments to the Code or the Treasury regulations thereunder or by subsequent judicial or administrative interpretation thereof, any of which may have retroactive effect. There can be no assurance that our opinion will be accepted by the Internal Revenue Service or, if challenged, by a court. We express no opinions other than as to the federal income tax law of the United States of America. This opinion does not address the various state, local or foreign tax consequences that may result from the transactions contemplated by the Merger Agreement and the Registration Statement.

Based upon and subject to the foregoing and to the limitations and qualifications set forth herein, it is our opinion that the discussion in the section of the Registration Statement entitled “Material U.S. Federal Income Tax Consequences of the Merger” constitutes the material U.S. federal income tax consequences of the Merger to U.S. holders of Floridian common stock.
