is given, and all statements herein are made, in the context of the foregoing.

          This opinion letter is based as to matters of law solely on applicable
provisions of the General Corporation Law of the State of Delaware, as amended,

(ii) assuming due execution, authentication, issuance and delivery of
the Exchange Notes as provided in the Indenture, the Exchange Notes will
constitute valid and binding obligations of the Company entitled to the benefits
of the Indenture and enforceable in accordance with their terms, except as the
enforcement thereof may be limited by bankruptcy, insolvency, reorganization,
moratorium or other laws affecting creditors' rights (including, without
limitation, the effect of statutory and other laws regarding fraudulent
conveyances, fraudulent transfers and preferential transfers) and as may be
limited by the exercise of judicial discretion and the application of principles
of equity including without limitation, requirements of good faith, fair
dealing, conscionability and materiality (regardless of whether the Exchange
Notes are considered in a proceeding in equity or at law).

          We assume no obligation to advise you of any changes in the foregoing
subsequent to the delivery of this opinion letter.  This opinion letter has been
prepared solely for your use in connection with the filing of the Registration
