as originals, (e) the conformity to the original documents of all documents
submitted to us as copies and (f) the genuineness of all signatures on the

     Based upon and subject to the foregoing and assuming that (a) the
Registration Statement and any amendments thereto (including any post-effective
amendments) will have become effective and comply with all applicable laws at
the time the Offered Securities are offered or issued as contemplated by the
Registration Statement, (b) a prospectus supplement will have been prepared and
filed with the Commission describing the Offered Securities offered thereby and
will at all relevant times comply with all applicable laws, (c) all Offered
Securities will be issued and sold in compliance with applicable federal and
state securities laws and in the manner stated in the Registration Statement and

issued will be duly authorized, created and, if appropriate, reserved for
issuance upon such conversion, exercise or exchange, we advise you that in our
opinion:
