"Registration Statement"). The Indenture is between the Company and United Trust

deemed advisable for the rendering of this opinion. In making our examination, 
we have

by the respective Guarantor and when executed, authenticated, and delivered in 
accordance with the terms of the Indenture and paid for in the manner and at the
price set forth in the Registration Statement, will constitute the legal, valid 
and binding obligation of each Guarantor in accordance with its terms, subject 
to applicable bankruptcy, insolvency, fraudulent conveyance, moratorium, 
reorganization or other similar laws affecting creditor's rights or debtor's 
obligations and to general principles of equity.
