Based upon the foregoing, we are of the opinion that the Shares have been duly authorized and, when sold as described in the Prospectus, the Shares will be validly issued, fully paid and nonassessable.

The foregoing opinions are limited to the federal laws of the United States, the Delaware General Corporation Law and the laws of the State of New York (including the statutory provisions and reported judicial decisions interpreting the foregoing).
