</B><P ALIGN="JUSTIFY">On October 19, 2005, Lyondell Chemical Company (the &quot;Company&quot;) issued a press release announcing that it will permanently cease toluene diisocyanate (&quot;TDI&quot;) production at its Lake Charles, Louisiana plant, as approved by its Board of Directors.  Previously, on September 20, 2005, the Company had announced an indefinite suspension of production at the 300 million pound per year TDI facility while the Company evaluated the long-term prospects for the plant.  Since production ceased soon after the September 20, 2005 announcement, the permanent decommissioning of the Lake Charles TDI facility is expected to be complete by the end of 2005.</P>


<P ALIGN="JUSTIFY">The decision to cease production at the Company's Lake Charles TDI facility was taken in response to poor financial profitability.  Based on the Company's evaluation of future plant capital requirements, high energy and raw material costs and poor projected industry utilization, the Company does not expect that the Lake Charles TDI business will return to profitability.  Hurricane Rita contributed to the decision, as it damaged the plant and contributed to increased energy costs.  </P>


<P ALIGN="JUSTIFY">The Company has approximately 280 employees at the Lake Charles TDI facility.  Efforts will be made to reduce the impact to employees, which is expected to include redeployment opportunities or severance benefits. </P>


<P ALIGN="JUSTIFY">In the third quarter of 2005, the Company will recognize a pre-tax, non-cash charge of $195 million for impairment of the carrying value of the plant and related assets.  In addition, in subsequent periods, the Company expects to incur various costs, including employee termination benefits of approximately $20 million, approximately $35 million associated with plant decommissioning and demolition, and approximately $10 million for contract terminations.  The Company's preliminary estimate of pre-tax, cash and non-cash charges that may be associated with this action is approximately $260 million.  In addition, there are multiple commercial arrangements associated with the TDI facility for which the cost of resolution cannot be determined at this time.  It is possible that the Company may face litigation associated with the shut down, which, depending on the outcome, may or may not be material.</P>
