This press release is being issued pursuant to, and in accordance with, Rule 135c under the Securities Act, and is neither an offer to sell nor a solicitation of an offer to buy the senior bonds or any other securities and it does not constitute an offer to purchase or a solicitation to sell any notes subject to the tender offer.
