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

     We have reviewed the Indenture, Article X of which contains the Guaranties 
and have made such legal and factual examination and inquiry which we have 
deemed advisable for the rendering of this opinion. In making our examination, 
we have

assured the genuiness of all signatures, the authenticity of all documents
submitted to us as originals and the conformity to all authentic original
documents of all documents submitted to us as copies. Based on the foregoing, it
is our opinion that:
     Each Guaranty issued by each respective Guarantor has been duly authorized 
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.

     The opinion expressed herein is rendered solely for your benefit in 
connection with the transactions contemplated hereby. The opinion expressed 
herein may not be used or relied upon by any person nor may this letter or any

     We hereby consent to the filing of this opinion as an exhibit to the 
Registration Statement and to the use of our name in the prospectus contained 
therein, under the caption "Legal Matters." Such consent does not constitute a 
consent under Section 7 of the Securities Act ("Section 7"), since in consenting
