This press release shall not constitute an offer to sell or the solicitation of an offer to buy, nor shall there be any sale of the Notes and related guarantees in any jurisdiction in which such offer, solicitation or sale would be unlawful prior to registration or qualification under the securities laws of any such jurisdiction.
