2.     It is inappropriate to include assumptions in a legal opinion that are
too broad, assume
       material facts underlying the opinion or any readily ascertainable
facts. Please have
       counsel remove the assumptions in paragraph (f) and (l) of Schedule 1 in
Exhibit 5.1, or
       tell us why they are necessary and appropriate.
3.     Schedule 2 paragraph (d) indicates you have limited your opinion to the
       documents in paragraph 2 of the opinion. It is not appropriate to limit
your opinion to
       specific documents or enquiries as indicated in paragraph 1.3 Your
opinion must clarify
       that counsel has reviewed all matters and made such inquiries as are
necessary to render
       its opinion. Please revise paragraph 1.3 and Schedule 2 paragraph (d).
