              Incorporation as certified by the Secretary of the Company on the
              date hereof as being complete, accurate and in effect.


          4.  The Amended and Restated By-laws of the Company, as certified by
              the Secretary of the Company on the date hereof as being complete,
              accurate and in effect.

          5.  Resolutions of the Board of Directors of the Company adopted on

              the date hereof as being complete, accurate and in effect,
              relating to the issuance and sale of the Exchange Notes and
              arrangements in connection therewith. 

          In our examination of the aforesaid documents, we have assumed the
genuineness of all signatures, the legal capacity of all natural persons, the
accuracy and completeness of all documents submitted to us, the authenticity of
all original documents, and the conformity to authentic original documents of
all documents submitted to us as copies (including telecopies). This opinion
letter 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,
and the contract law of the State of New York (but not including any statutes,
ordinances, administrative decisions, rules or regulations of any political
subdivision of the State of New York).  We express no opinion herein as to any
other laws, statutes, ordinances, rules or regulations not specifically referred
to above.

          Based upon, subject to and limited by the foregoing, we are of the
opinion that the Exchange Notes have been duly authorized on behalf of the
Company and that, (i) following the effectiveness of the Registration Statement
and receipt by the Company of the Senior Notes in exchange for the Exchange
Notes as specified in the resolutions of the Board of Directors referred to
above, and (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 may be limited by
bankruptcy, insolvency, reorganization, moratorium or other laws affecting
creditors' rights (including, without limitation, the effect of statutory 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
Statement on the date of this opinion letter and should not be quoted in whole
