subject to an over-allotment option) (the "Shares"), pursuant to the Prospectus
Supplement filed on or about November 6, 2003 (the "Prospectus Supplement"), to

(the "Commission") on January 10, 2002 (File No. 333-76532), including Amendment
Nos. 1 and 2 thereto, and declared effective by the Commission (the

the authenticity of all documents submitted to us as originals, the conformity
to authentic original documents of all documents submitted to us as copies and
the truth, accuracy and completeness of the information, representations and
warranties contained in the records, documents, instruments and certificates we
have reviewed.

         We are opining herein as to the effect on the subject transaction only
of the General Corporation Law of the State of Delaware, including statutory and
reported decisional law thereunder, and we express no opinion with respect to
the applicability thereto, or the effect

         Subject to the foregoing, we are of the opinion that the Shares, when
issued in the manner described in the Prospectus Supplement and the Registration
Statement, will be duly authorized, validly issued, fully paid and
non-assessable.

Prospectus Supplement. In giving such consent, we do not believe that we are
"experts" within the meaning of such term as used in the Securities Act of 1933,

any part of the Registration Statement, including this opinion as an exhibit or
otherwise.
