HOUSTON, Dec. 6 /PRNewswire-FirstCall/ -- Lyondell Chemical Company (NYSE: LYO) and its subsidiaries Equistar Chemicals, LP ("Equistar") and Equistar Funding Corporation (together with Equistar, the "Equistar Issuers") announced today that, as of 5 p.m. EST on Dec. 5, 2007 (the "Consent Payment Deadline"), a total of approximately $3.97 billion in aggregate principal amount of the outstanding debt securities listed in Table 1 below (collectively, the "Notes") issued by Lyondell or the Equistar Issuers, as applicable, has been tendered pursuant to the previously announced cash tender offers (the "Offers") and consent solicitations (the "Consent Solicitations"). As a result, Lyondell and the Equistar Issuers have received the required consents from holders to amend each of the indentures governing the applicable Notes. Upon Lyondell and the Equistar Issuers accepting for purchase at least a majority in aggregate principal amount of the applicable Notes outstanding, each of the supplemental indentures effecting the proposed amendments as described in the Offer to Purchase and Consent Solicitation Statement dated Nov. 20, 2007 (the "Offer and Consent Statement") will become operative.

The Offer for each series of Notes will expire at 12:01 a.m. EST on Dec. 20, 2007, unless extended or earlier terminated by Lyondell or the Equistar Issuers, as applicable, in their sole discretion (the "Expiration Date"). Withdrawal rights with respect to the Notes and revocation rights with respect to corresponding consents have expired. Accordingly, holders may not withdraw any Notes previously or hereafter tendered, except as contemplated in the applicable Offers.

The total consideration was determined as of 2 p.m. EST on Dec. 5, 2007. The total consideration per $1,000 principal amount of the Notes validly tendered at or prior to the Consent Payment Deadline, not validly withdrawn and accepted for payment (the "Total Consideration") is set forth in Table 1 below, of which $30 is the consent payment. The tender offer consideration per $1,000 principal amount of the Notes validly tendered after the Consent Payment Deadline, not validly withdrawn and accepted for payment (the "Tender Offer Consideration") equals the Total Consideration minus the $30 consent payment. In each case, accrued and unpaid interest on the Notes will be paid in cash from the most recent interest payment date applicable to the Notes to, but not including, the applicable payment date for the Offers. The applicable payment date for Notes tendered on or prior to the Consent Payment Deadline is expected to be on or about Dec. 20, 2007. The applicable payment date for Notes tendered after the Consent Payment Deadline and on or prior to the Expiration Date is expected to be on or about Dec. 21, 2007.
