<P>On May 2, 2007, Lyondell Chemical Company (&quot;Lyondell&quot;) announced that as of 5:00 p.m. EDT on May 1, 2007, it has received consents from holders constituting a majority in principal amount of its outstanding 10.5% Senior Secured Notes due 2013 (the &quot;2013 Notes&quot;) pursuant to its previously announced consent solicitation.  Thus, the amendment to the Indenture governing the 2013 Notes has been approved.  The Indenture governing the 2013 Notes among Lyondell, the subsidiary guarantors party thereto, and The Bank of New York as Trustee previously required Lyondell to refinance subordinated debt with new subordinated debt. The Supplemental Indenture permits the refinancing of subordinated debt with senior debt. The Supplemental Indenture became effective on May 2, 2007 and is being filed with this Current Report on Form 8-K as Exhibit 4.15(d). </P>
<P>Lyondell also announced that, as of 5:00 p.m. EDT on May 1, 2007, approximately $270 million in aggregate principal amount of its 11.125% Senior Secured Notes due 2012 (the "2012 Notes"), representing approximately 97% of the outstanding principal amount of the 2012 Notes, have been tendered pursuant to its previously announced cash tender offer and consent solicitation.  The amount tendered constitutes a majority in principal amount of the outstanding 2012 Notes.  Thus, amendments to the Indenture governing the 2012 Notes among Lyondell, the subsidiary guarantors party thereto, and The Bank of New York as Trustee have been approved.  The amendments include the elimination of substantially all the restrictive covenants, certain events of default and certain other provisions. The Supplemental Indenture became effective on May 2, 2007 and is being filed with this Current Report on Form 8-K as Exhibit 4.12(d).</P>
<P>The press release regarding these matters is being filed with this Current Report on Form 8-K as Exhibit 99.1.</P>
