of Directors; (ii) a Certificate of the Secretary of State of the State of
Delaware as to the legal existence of the Company; and (iii) such other

Based upon the foregoing, and having regard for such legal

State of Delaware.

Company will be duly authorized, validly issued, fully paid and
nonassessable.
We hereby consent to the filing of this opinion as an exhibit to the
Registration Statement and to the references to us under the caption "Legal
Matters" in the Prospectus forming a part of the Registration Statement.
Very truly yours,
HUTCHINS, WHEELER & DITTMAR
