          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.   Unanimous Written Consent of the Board of Directors of the
               Company dated  February 11, 1999, as certified by the Secretary
               of the Company 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.  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 Outstanding 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 other law 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).

          The Opinion expressed in the Paragraph above shall be understood to 
mean only that (i) if there is a default in performance of an obligation, (ii) 
if a failure to pay or other damage can be shown and (iii) if the defaulting 
party can be brought into a court which will hear the case and apply the 
governing law, then, subject to the availability of defenses, and to the 
exceptions set forth in the Paragraph above, the court will provide a money 
damage (or perhaps injunctive or specific performance) remedy.
        
          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
or in part or otherwise referred to, nor filed with or furnished to any
governmental agency or other person or entity, without the prior written consent
of this firm.

          We hereby consent to the filing of this opinion letter as Exhibit 5.1
to the Registration Statement and to the reference to this firm under the
caption "Legal Matters" in the prospectus constituting a part of the
Registration Statement.  In giving this consent, we do not thereby admit that we
