Based upon the foregoing, we are of the opinion that the Shares to be offered pursuant to the Registration Statement, if sold as described in the Registration Statement will be legally issued, fully paid and nonassessable, provided that no less than par value is paid for any Shares. No opinion is expressed herein as to the application of state securities or Blue Sky laws. This opinion is furnished by us as counsel to you and is solely for your benefit. Neither this opinion nor copies hereof may be relied upon by, delivered to, or quoted in whole or in part to any governmental agency or other person without our prior written consent.
