The Outstanding Notes were issued, and the Exchange Notes are issuable, pursuant to an Indenture, dated March 1, 2004, by and among the Company, the Guarantors and Wells Fargo Bank, N.A., as Trustee (the "Indenture"). Based on the foregoing, and subject to the qualifications and limitations set forth herein, we advise you that: 1. The Exchange Notes, when issued, authenticated and delivered by the Company and the Trustee in accordance with the terms of the Indenture, and when issued in exchange for Outstanding Notes as contemplated in the Registration Statement, will be legally binding and valid obligations of the Company, entitled to the benefits of the Indenture and enforceable against the Company in accordance with their terms. 2. The guarantees by the Guarantors to be endorsed on the Exchange Notes, when the Exchange Notes are issued, authenticated and delivered by the Company and the Trustee in accordance with the terms of the Indenture, and when issued as contemplated in the Registration Statement, will be legally binding and valid obligations of the Guarantors enforceable against each of them in accordance with their terms. In rendering this opinion, we have reviewed and relied upon the Indenture, the Outstanding Notes, the form of Exchange Notes and such documents, records, and other instruments of the Company and the Guarantors as we have deemed necessary. The opinions set forth above are subject to the following qualifications: (i) The opinions are subject to and may be limited by (a) applicable bankruptcy, insolvency, liquidation, fraudulent conveyance or transfer, moratorium, reorganization, or other similar laws affecting creditors' rights generally; (b) general equitable principles and rules of law governing specific performance, estoppel, waiver, injunctive relief, and other equitable remedies (regardless of whether enforcement is sought in a proceeding at law or in equity), and the discretion of any court before which a proceeding may be brought; (c) duties and standards of good faith, reasonableness and fair dealing imposed on creditors and parties to contracts; and (d) a court determination that any fees payable pursuant to a provision requiring the payment of attorneys' fees is reasonable. (ii) We have assumed: (a) the genuineness of the signatures and the authenticity of documents submitted to us as originals, and the conformity to originals of all documents submitted to us as certified or photostatic copies; (b) that such documents accurately describe the mutual understanding of the parties as to all matters contained therein and that no other agreements or undertakings exist between the parties that would affect the documents relating to the transactions contemplated by such documents and agreements; (c) the due authorization, execution, and delivery of the documents discussed herein by all parties thereto except the Company and the Guarantors, that such documents will be valid and binding upon, and enforceable in accordance with their terms against, all parties thereto except the Company and the Guarantors, and that the execution, delivery, and performance of such documents by parties other than the Company and the Guarantors will not violate any provision of any charter document, law, rule, regulation, judgment, order, decree, agreement or other document binding upon or applicable to such other parties or their respective assets; (d) the accuracy, completeness, and genuineness of all representations and certifications made to or obtained by us, including those of public officials; and (e) the accuracy and completeness of records of the Company and the Guarantors. (iii) We express no opinion regarding compliance by the Company or any Guarantor with any financial covenants required to be maintained by them under any agreement or document, or as to the financial ability of the Company or any Guarantors to meet its obligations under the documents described herein.
