connection with the Company's offer (the "Exchange Offer") to exchange up to
$54,654,296 principal amount of the Company's 12 1/2% Senior Subordinated
Secured Notes due 2008 that have been registered under the Securities Act of

the Company's outstanding 12 1/2% Senior Subordinated Secured Notes due
2008 (the "Old Notes"), which Old Notes have also been guaranteed by each of the
Note Guarantors.

         We have examined originals or copies, certified or otherwise identified
to our satisfaction, of such documents, corporate and limited liability company
records, certificates of public officials and other instruments as we have
deemed necessary or advisable for the purpose of rendering this opinion.

         For purposes of our opinion, we have assumed that each of the
Non-Delaware Guarantors (i) is a corporation duly organized, validly existing
and in good standing under the laws of its state of organization, (ii) has the
corporate power and authority to consummate the Exchange Offer and the
transactions contemplated thereby, including the execution, delivery and
performance of its obligations under the New Notes or the Guarantees of the New
Notes, as the case may be, (iii) has taken all requisite corporate action to
authorize the performance of the Exchange Offer and the transactions
contemplated thereby, including the execution, delivery and performance of its
obligations under the New Notes or the Guarantees of the New Notes, as the case
may be, and (iv) will duly execute and deliver the New Notes and any other
documents necessary to effect the Exchange Offer.

         Upon the basis of the foregoing, we are of the opinion that:

         1. When the New Notes have been duly executed, authenticated and
delivered in accordance with the Indenture dated as of May 30, 2002 (the
"Indenture") among the Company, the Note Guarantors and The Bank of New York, as
Trustee, in exchange for the Old Notes in accordance with the Indenture and the
Exchange Offer, the New Notes will be legally valid and binding obligations of
the Company, enforceable against the Company in accordance with their terms,
except as may be limited by bankruptcy, insolvency, reorganization, moratorium
or similar laws relating to or affecting creditors' rights generally (including,
without limitation, fraudulent conveyance laws), and by general principles of
equity including, without limitation, concepts of materiality, reasonableness,
good faith and fair dealing and the possible unavailability of specific
performance or injunctive relief, regardless of whether considered in a
proceeding in equity or at law.

         2. When the New Notes have been duly executed, authenticated and
delivered in accordance with the Indenture in exchange for the Old Notes in
accordance with the Indenture and the Exchange Offer, the Guarantees will be the
legally valid and binding obligations of the Note Guarantors, enforceable
against the Note Guarantors in accordance with their terms, except as may be
limited by bankruptcy, insolvency, reorganization, moratorium or similar laws
relating to or affecting creditors' rights generally (including, without
limitation, fraudulent conveyance laws), and by general principles of equity
including, without limitation, concepts of materiality, reasonableness, good
faith and fair dealing and the possible unavailability of specific performance
or injunctive relief, regardless of whether considered in a proceeding in equity
or at law.
