We refer to the Registration Statement on Form S-8 (the "Registration

As counsel for the Company, we have examined such corporate records and other

for the purposes of this opinion. Upon the basis of that examination, we advise
you that, in our opinion, the Shares have been duly and validly authorized and,
upon issuance thereof by the Company and receipt of the consideration by the

                                    Very truly yours,
