Where we have considered it appropriate, with respect to certain facts we have relied, without investigation or analysis of any underlying data contained therein, upon (i) certificates or other comparable documents of public officials and (ii) certificates of officers or other appropriate representatives of the Company and the Guarantors. In addition, we have also examined originals or copies, certified to our satisfaction, of documents and agreements listed in certificates signed by duly authorized officers of the Company and the Guarantors dated as of the date hereof.

To the extent that obligations of the Company and of the Guarantors may be dependent upon such matters, we have relied solely upon certificates regarding the Company and each Guarantor from the Delaware Secretary of State, each dated as of the corresponding date indicated in Schedule II attached hereto, as to the conclusions that (i) the Company and each Corporate Guarantor is a corporation and is in good standing and (ii) each LLC Guarantor is a limited liability company and is in good standing.

1. When the Registration Statement has become effective under the Securities Act and the Exchange Notes have been duly executed by the Company, authenticated by the Trustee in accordance with the Indenture, and issued and delivered against receipt of the Original Notes surrendered in exchange therefor in accordance with the terms of the Exchange Offer, each Exchange Note will be the valid and binding obligation of the Company.

2. When the Registration Statement has become effective under the Securities Act and the Exchange Notes have been duly executed by the Company, authenticated by the Trustee in accordance with the Indenture, and issued and delivered against receipt of the Original Notes surrendered in exchange therefor in accordance with the terms of the Exchange Offer, each Guarantee will be the valid and binding obligation of the Guarantor party thereto.
