Holders who tender their 9 3/4 percent Senior Notes will be required to consent to the proposed amendments and holders may not deliver consents to the proposed amendments without tendering their 9 3/4 percent Senior Notes in the tender offer. The tender offer is conditioned upon, among other things, the completion by the Company of certain related financing transactions. Simultaneous to the tender offer, the Company is seeking consents from the record holders (as of September 19, 2003) of its 10 1/8 percent Senior Notes to amend the indenture under which the 10 1/8 percent Senior Notes were issued.
