registration of $300,000,000 aggregate principal amount of the Company's 7-1/4%
Convertible Notes due 2010 (the "Notes") issued under the Indenture, dated

Trustee (the "Indenture"), common stock issuable upon conversion of the Notes

documents. As to any facts material to our opinion, we have, when relevant facts
were not independently established, relied upon the aforesaid records,
certificates and documents.

      As counsel for the Company, we are of the opinion that:

      1. The Company is a corporation duly organized and legally existing under
the laws of the State of Nevada and is in good standing under said laws, and
that it is legally qualified to hold property and do business under said laws.

      2. When the following steps shall have been taken, the Notes will be, to
the extent that Nevada law governs such issues, valid, legal and binding
obligations of the Company (except as the enforcement thereof may be limited by
bankruptcy, insolvency, reorganization, moratorium (including, without
limitation, all laws relating to fraudulent transfers), or other similar laws

            authorizations and in accordance with the terms and provisions of
            the Indenture.

      3. The Common Stock and the Rights will be validly issued, fully paid and
non-assessable upon issuance of the Common Stock and the Rights in conformity
with the Registration Statement and the Indenture.

      The foregoing opinions are limited to the matters expressly set forth
