Description of Notes restrictive covenants		The indenture governing the Notes contains restrictive covenants that, among other things, limit the ability of the Company and its subsidiaries to (i) incur additional debt, (ii) pay dividends and make other restricted payments, (iii) create or permit certain liens, (iv) issue or sell capital stock of the Company's restricted subsidiaries, (v) use the proceeds from sales of assets and subsidiary stock, (vi) create or permit restrictions on the ability of the Company's restricted subsidiaries to pay dividends or make other distributions to the Company, (vii) enter into transactions with affiliates, (viii) enter into sale and leaseback transactions and (ix) consolidate or merge or sell all or substantially all of the Company's assets. The foregoing limitations are subject to exceptions as set forth in the Notes. In addition, if in the future the Notes have an investment grade credit rating from both Moody's Investors Service and Standard & Poor's Ratings Services and no default has occurred and is continuing, certain of these covenants will, thereafter, no longer apply to the Notes for so long as the Notes have an investment grade credit rating by both rating agencies.
