The New Notes will be guaranteed (the "Guarantees") by the Company's subsidiaries listed in the Registration Statement on Form S-4 (the "Registration Statement") filed by the Company with the Securities and Exchange Commission on June 23, 2004 (each, a "Guarantor"). The Old Notes were issued, and it is proposed that the New Notes be issued, under an indenture, dated as of March 25, 2004, among the Company, the Guarantors named therein and Wachovia Bank, National Association, as trustee (the "Trustee"), as supplemented by a Supplemental Indenture No. 1, dated as of June 22, 2004, among the Company, the Additional Guarantors named therein and the Trustee (as so supplemented and as may be further supplemented or amended from time to time, the "Indenture"). We have examined originals or copies, certified or otherwise identified to our satisfaction, of such documents, corporate records, certificates of public officials and other instruments as we have deemed necessary or advisable for the purpose of rendering this opinion. Upon the basis of the foregoing, and subject to the assumptions and qualifications set forth below, we are of the opinion that: (1) The New Notes, when authorized, executed, authenticated and delivered in exchange for the Old Notes in accordance with the terms of the Exchange Offer and the Indenture, will be valid and binding obligations of the Company enforceable in accordance with their terms, except (i) as such enforcement may be limited by bankruptcy, insolvency or similar laws affecting creditors' rights generally, (ii) as such enforcement may be limited by general principles of equity, regardless of whether enforcement is sought in a proceeding at law or in <Page> equity, and (iii) to the extent that a waiver of rights under any usury or stay law may be unenforceable; and (2) When the New Notes are authorized, executed, authenticated and delivered in exchange for the Old Notes in accordance with the terms of the Exchange Offer and the Indenture, the Guarantee of each Guarantor will be a valid and binding obligation of such Guarantor, enforceable in accordance with its terms, except (i) as such enforcement may be limited by bankruptcy, insolvency, fraudulent transfer or conveyance or similar provisions of applicable law, or similar laws affecting creditors' rights generally, (ii) as such enforcement may be limited by general principles of equity, regardless of whether enforcement is sought in a proceeding at law or in equity, and (iii) to the extent that a waiver of rights under any usury or stay law may be unenforceable. We hereby confirm the opinion set forth under the caption "Taxation" in the prospectus that is part of the Registration Statement.

(b) We express no opinion as to whether a United States federal court would have jurisdiction over a controversy arising under a Guarantee. (c) Our opinion set forth in paragraph (2) above may be subject to possible judicial action giving effect to governmental actions or foreign laws affecting creditors' rights. (d) We have assumed that (i) all signatures on all documents examined by us are genuine and that where any such signature purports to have been made in a corporate, governmental, fiduciary or other capacity, the person who affixed such signature had the due authority to do so, (ii) certain factual matters contained in certificates of public officials and 2 <Page> certificates and letters of the Company and the Guarantors, as the case may be, are accurate, true and correct, and (iii) photostat copies of such documents, records and certificates conform to the originals.
