appropriate for the purposes of this opinion.
Based upon the foregoing, we are of the opinion that the foregoing shares

authorized and, assuming receipt of the consideration to be paid therefor, upon
delivery as provided in the Registration Statement, will be legally and validly
issued, fully paid and non-assessable (except for the potential liability of
shareholders described in the Fund's Statement of Additional Information.
We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the reference to us in the Registration Statement.
We do not thereby admit that we are within the category of persons whose consent
is required under Section 7 of the 1933 Act or the rules and regulations of the
Securities and Exchange Commission thereunder.
