The securities specified in clauses (i) through (ix) above are collectively referred to herein as the “Securities”. In addition, the Registration Statement also relates to the offer and sale, from time to time, of up to 477,743,590 shares of Common Stock held by the selling securityholder identified in the Registration Statement.

In connection with this opinion, we have examined originals, or copies certified or otherwise identified to our satisfaction, of such corporate records, certificates of corporate officers and government officials and such other documents as we have deemed necessary or appropriate for the purposes of this opinion. As to various questions of fact material to this opinion, we have relied upon representations of officers or directors of the Registrants and documents furnished to us by the Registrants without independent verification of their accuracy. We have also 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.
