As part of the corporate actions taken and to be taken in connection with issuance of any Securities to be issued and sold from time to time under the Registration Statement, the Board of Directors, a committee thereof or certain authorized officers of the Company as authorized by the Board of Directors will, before such Securities are issued under the Registration Statement, duly authorize the issuance and approve the terms of such Securities (the “Corporate Proceedings”).

You have provided us with a draft prospectus (the “Prospectus”) that is a part of the Registration Statement. The Prospectus provides that it will be supplemented in the future by one or more supplements thereto (each, a “Prospectus Supplement”) in connection with each offering of Securities. This opinion is being furnished in connection with the requirements of Item 601(b)(5) of Regulation S-K under the Act, and no opinion is expressed herein as to any matter pertaining to the contents of the Registration Statement, the Prospectus or any Prospectus Supplement, other than as expressly stated herein with respect to the issue of the Securities. It is understood that the opinions set forth below are to be used only in connection with the offer while the Registration Statement is in effect.

In our capacity as your counsel in connection with such registration, we have reviewed and are familiar with such documents, certificates, Corporate Proceedings and other materials, including an examination of originals or copies certified or otherwise identified to our satisfaction of the Certificate of Incorporation and By-laws of the Company, Governing Documents and the Registration Statement (collectively, the “Constituent Documents”), and have reviewed such questions of law, as we have considered relevant or necessary as a basis for this opinion.

In our examination, we have assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, and the conformity to authentic original documents of all documents submitted to us as copies. For purposes of this opinion, we have assumed that proper proceedings in connection with the authorization and issuance or sale of the Securities will be timely and properly completed, in accordance with all requirements of applicable federal laws and the Florida Statutes, in the manner presently proposed. We have assumed and have not verified the accuracy of the factual matters of each document we have reviewed.

As to facts material to the opinions, statements and assumptions expressed herein, we have, with your consent, relied upon oral or written statements and representations of officers and other representatives of the Company and others. We have specifically relied upon the certification of an officer of the Company signed on even date herewith. In addition, we have obtained and relied upon such certificates and assurances from public officials as we have deemed necessary.

With respect to the Securities to be offered and sold by the Company, we have also assumed that (a) the Registration Statement shall have become and remain effective under the Securities Act, a Prospectus Supplement shall have been prepared and filed with the Commission describing the Securities, and such Securities shall have been issued and sold in accordance with the terms set forth in such Prospectus Supplement; (b) such Securities, as issued and delivered, comply with any requirements and restrictions imposed by any court or governmental or regulatory body applicable to the Company; (c) at the time of any offering or sale of any Securities, there shall be a sufficient number of shares of Common Stock or Preferred Stock, authorized and unissued under the Certificate, and not otherwise reserved for issuance, except in connection with the issuance of the Securities; (d) at the time of issuance or sale of the Securities, the Company shall validly exist and shall be in good standing under the laws of the State of Florida, and, in the case of Securities, the Company shall have the necessary corporate power for such issuance; (e) any definitive purchase, underwriting or similar agreement with respect to any Securities, if applicable, shall have

been duly authorized, executed and delivered by the parties thereto and shall constitute legally valid and binding obligations of the parties thereto, enforceable against each of them in accordance with their respective terms, at the time of issuance of the applicable Securities; (f) certificates representing the Securities, if any, shall have been duly executed, countersigned, registered and delivered, or if uncertificated, valid book-entry notations shall have been made in the share or other register of the Company, in each case in accordance with the Constituent Documents, and in the manner contemplated by the Registration Statement and/or the applicable Prospectus Supplement, against payment therefor in an amount not less than the par value thereof, or such other consideration determined by the Board of Directors, or an authorized committee thereof, as permitted under the Florida Statutes, in accordance with the provisions of any applicable definitive purchase agreement, underwriting agreement, or similar agreement approved by the Company; and (g) the Constituent Documents shall be in full force and effect and shall not have been amended, restated, supplemented or otherwise altered, and there shall be no authorization of any such amendment, restatement, supplement or alteration, in each case since the date hereof.

Subject to the foregoing and the other matters set forth herein, it is our opinion that as of the date hereof:

The opinions set forth above are subject to the following exceptions, limitations and qualifications: (i) the effect of bankruptcy, insolvency, reorganization, fraudulent conveyance, moratorium or other similar laws now or hereafter in effect relating to or affecting the rights and remedies of creditors; (ii) the effect of general principles of equity, including without limitation, concepts of materiality, reasonableness, good faith and fair dealing and the possible unavailability of specific performance or injunctive relief, regardless of whether enforcement is considered in a proceeding in equity or at law, and the discretion of the court before which any proceeding therefor may be brought; (iii) the unenforceability under certain circumstances under law or court decisions of provision providing for the indemnification of, or contribution to, a party with respect to liability where such indemnification or contribution is contrary to public policy. We express no opinion concerning the enforceability of any waiver of rights or defenses with respect to stay, extension or usury laws. Our opinion expressed herein is also subject to the qualification that no term or provision hereof shall be included in: (a) the Certificate of Designation relating to any series of the Preferred Stock, (b) the Indenture, (c) the Warrant Agreement, (d) the Unit Agreement, (e) the Rights Agreement, or (f) any other agreement or instrument pursuant to which any of the Securities are to be issued that would affect the validity of such opinion.

Our opinion is limited to the federal laws of the United States and the Florida Statutes. We express no opinion as to the effect of the law of any other jurisdiction. Our opinion is rendered as of the date hereof, and we assume no obligation to advise you of changes in law or fact (or the effect thereof on the opinions expressed herein) that hereafter may come to our attention.
