otherwise identified to our satisfaction, of such records, agreements,
certificates, instruments and other documents as we have considered necessary or
appropriate for the purposes of this opinion.

     In rendering this opinion, we have assumed:

          (a) The Guarantee of each of the Massachusetts Guarantors has been
     legally issued, and the Supplemental Indenture constitutes the binding
     agreement (and, as a result, the Indenture constitutes the binding
     agreement) of each of the Massachusetts Guarantors to the extent the
     binding nature of the Supplemental Indenture and the Indenture involves
     matters governed by the laws of the Commonwealth of Massachusetts;

          (b) The Guarantee of each of the Florida Guarantors has been legally
     issued, and the Supplemental Indenture constitutes the binding agreement
     (and, as a result, the Indenture constitutes the binding agreement) of each
     of the Florida Guarantors to the extent the binding nature of the
     Supplemental Indenture and the Indenture involves matters governed by the
     laws of the State of Florida;

          (c) The Guarantee of the New Jersey Guarantor has been legally issued,
     and the Supplemental Indenture constitutes the binding agreement (and, as a
     result, the Indenture constitutes the binding agreement) of the New Jersey
     Guarantor to the extent the binding nature of the Supplemental Indenture
     and the Indenture involves matters governed by the laws of the State of New
     Jersey;

          (d) The due and valid execution and delivery of the Indenture and the
     Supplemental Indenture by the Trustee, and that the Indenture and the
     Supplemental Indenture each constitutes the legal, valid and binding
     agreement of the Trustee; and

          (e) The genuineness of all signatures, the legal capacity of all
     natural persons, the authenticity of all documents submitted to us as
     originals, the conformity to original documents of all documents submitted
     to us as certified or photostatic copies and the authenticity of the
     originals of such latter documents.

     Based upon the foregoing, and in reliance thereon, and subject to receipt
by the Company and the Guarantors from the Commission of an order declaring the
Registration Statement effective, we are of the opinion that:

     1.  The New Notes, when issued and delivered in exchange for the Old Notes
in accordance with the terms of the Exchange Offer and when executed and
authenticated as specified in the Indenture, will be legally issued and will
constitute binding obligations of the Company.

     2.  The New Preferred Stock, when issued and delivered in exchange for the
Old Preferred Stock in accordance with the terms of the Exchange Offer, will be
legally issued, fully paid and nonassessable.

     3.  The additional shares of 13 1/2% Exchangeable Preferred Stock
Mandatorily Redeemable 2010 of the Issuer that may be issued in payment of
dividends with respect to the New Preferred Stock, when issued and delivered in
accordance with the terms of the Certificate of Designation, will be legally
issued, fully paid and nonassessable.

     4.  Each Guarantee of a Delaware Guarantor, when issued and delivered in
connection with the exchange of the Old Notes in the manner described in the
Registration Statement and when the New Notes and all of the Guarantees have
been executed and, in the case of the New Notes, authenticated, as specified in
the Indenture, will be legally issued and will constitute a binding obligation
of such Delaware Guarantor.

     5.  Each Guarantee of an Other Guarantor, when issued and delivered in
connection with the exchange of the Old Notes in the manner described in the
Registration Statement and when the New Notes and all of the Guarantees have
been executed and, in the case of the New Notes, authenticated, as specified in
the Indenture, will be legally issued and will constitute a binding obligation
of such Other Guarantor to the extent the legal issuance and binding nature of
such Guarantee involves matters governed by the laws of the State of New York or
the General Corporation Law of the State of Delaware.

     The foregoing opinions are subject to the following exceptions,
qualifications and limitations:

     A.  We render no opinion as to matters involving the laws of any
jurisdiction other than the State of New York and the General Corporation Law of
the State of Delaware.  This opinion is limited to the effect of the present
state of the laws of the States of New York and Delaware and the facts as they
presently exist.  We assume no obligation to revise or supplement this opinion
in the event of changes in such laws or the interpretations thereof or in the
event of changes in such facts.

     B.  Our opinions set forth herein are subject to (i) the effect of any
bankruptcy, insolvency, reorganization, moratorium, arrangement or similar laws
affecting the enforcement of creditors' rights generally (including, without
limitation, the effect of statutory or other laws regarding fraudulent transfers
or preferential transfers) and (ii) general principles of equity, regardless of
whether a matter is considered in a proceeding in equity or at law, including,
without limitation, concepts of materiality, reasonableness, good faith and fair
dealing.  Without limitation, we express no opinion as to the ability to obtain
specific performance, injunctive relief or other equitable relief as a remedy
for noncompliance with any of the Note Documents.

     C.  We express no opinion with respect to the validity, binding nature or
enforceability of any provision of the Note Documents to the effect that rights
or remedies are not exclusive, that every right or remedy is cumulative and may
be exercised in addition to any other right or remedy, that the election of some
particular remedy does not preclude recourse to one or more others or that
failure to exercise or delay in exercising rights or remedies will not operate
as a waiver of any such right or remedy.

     D.  We express no opinion as to the effect on the enforceability of the
Guarantees against any Guarantor of any facts or circumstances that would
constitute a defense to the obligation of a guarantor or surety, unless such
defense has been waived effectively by such Guarantor.

     E.  We express no opinion as to the validity, binding nature or
enforceability (i) of provisions in the Note Documents providing for
indemnification or contribution or (ii) of any provision of any Note Document
insofar as it provides for the payment or reimbursement of costs and expenses or
indemnification for claims, losses or liabilities in excess of a reasonable
amount determined by any court or other tribunal.

     F.  We express no opinion with respect to the validity, binding nature or
enforceability of (i) any waivers of unknown future rights or waivers of rights
existing, or duties owed, that are broadly or vaguely stated or do not describe
the right or duty purportedly waived with reasonable specificity, (ii) any
waivers or consents (whether or not characterized as a waiver or consent in the
Note Documents) relating to the rights of the Company or any Guarantor or duties
owing to any of them existing as a matter of law, to the extent such waivers or
consents are found to be against public policy or are ineffective pursuant to
applicable statutes or judicial decisions, (iii) any waivers or variations of
rights of a debtor, including a guarantor, (iv) provisions in the Note Documents
imposing late payment charges or an increase in interest rate, upon delinquency
in payment or the occurrence of a default, to the extent that such provisions
are found to constitute a forfeiture or impose a penalty, (vi) covenants (other
than covenants relating to the payment of money, including payment of principal,
interest, indemnities and expenses) to the extent they are construed to be
independent requirements as distinguished from conditions precedent to the
occurrence of an event of default, and (vii) any rights of setoff (other than
such rights provided by Section 151 of the New York Debtor and Creditor Law Code
as interpreted by applicable judicial decisions).

     G.  We express no opinion as to any provisions of the Note Documents
requiring written amendments or waivers of such documents insofar as it suggests
that oral or other modifications, amendments or waivers could not be effectively
agreed upon by the parties or that the doctrine of promissory estoppel might not
apply.
