Registration Statement.

         In connection therewith, we have examined and relied upon the original
or a copy, certified to our satisfaction, of (i) the Amended and Restated
Articles of Incorporation and the Bylaws of the Company; (ii) actions of the
Board of Directors of the Company authorizing the offering and the issuance of
the Shares and related matters; (iii) the Registration Statement and exhibits
thereto; and (iv) such other documents and instruments as we have deemed
necessary for the expression of opinions herein contained. In making the
foregoing examinations, we have assumed the genuineness of all signatures and
the authenticity of all documents submitted to us as originals, and the
conformity to original documents of all documents submitted to us as certified
or photostatic copies. As to various questions of fact material to this opinion,
we have relied, to the extent we deem reasonably appropriate, upon
representations or certificates of officers or directors of the Company and upon
documents, records and instruments furnished to us by the Company, without
independently checking or verifying the accuracy of such documents, records and
instruments.

         Based upon the foregoing examination, we are of the opinion that (i)
the Shares to be sold by the Company pursuant to the Registration Statement have
been duly and validly authorized and, when issued and delivered in accordance
with the Purchase Agreement filed as Exhibit 1.1 to the Registration Statement
will be validly issued, fully paid and nonassessable, and (ii) the Shares to be
sold by the Selling Shareholders pursuant to the Registration Statement have
been duly and validly authorized and issued and are fully paid and
nonassessable.

         We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the use of our name under the caption "Legal
Matters" in the Prospectus forming a part of the Registration Statement. In
giving such consent, we do not admit that we come within the category of persons
whose consent is required by Section 7 of the Act or the rules and regulations
of the Commission thereunder.

                                               Sincerely,
