As described in the Registration Statement, sales of the Shares by the Selling Stockholders may be effected from time to time in one or more transactions, including block trades, in negotiated transactions or in a combination of such methods of sale. In reaching the conclusions expressed in this opinion, we have (a) examined such certificates of public officials and of corporate officers and directors and such other documents and matters as we have deemed necessary or appropriate, (b) relied upon the accuracy of facts and information set forth in all such documents, and (c) assumed the genuineness of all signatures, the authenticity of all documents submitted to us as originals, the conformity to original documents of all documents submitted to us as copies, and the authenticity of the originals from which all such copies were made.
