Lyondell and Millennium Announce Agreement to Combine

HOUSTON and HUNT VALLEY, Md., March 29 /PRNewswire-FirstCall/ -- Lyondell Chemical Company (NYSE: LYO) and Millennium Chemicals Inc. (NYSE: MCH) today announced that their Boards of Directors have approved, and the companies have executed, a definitive agreement for a stock-for-stock business combination of the companies, expected to be tax-free to the shareholders of Millennium and the companies. The transaction will create North America's third-largest independent, publicly traded chemical producer with combined pro forma 2003 revenues of more than $11 billion and market capitalization of nearly $4 billion.

Millennium shareholders will receive between 0.95 and 1.05 shares of Lyondell common stock for each share of Millennium common stock, depending on the volume-weighted average price for the Lyondell shares for the 20 trading days ending on the third trading day before closing. Millennium shareholders will receive 0.95 shares of Lyondell stock if the average Lyondell stock price is $20.50 or greater, and 1.05 if it is $16.50 or less. Between the two prices, the exchange ratio varies proportionately.

The new shares will be entitled to receive the same cash dividend as existing outstanding Lyondell shares. Based on recent trading, the transaction is valued at approximately $2.3 billion including approximately $1.3 billion of Millennium net debt.

The transaction is subject to customary conditions including approval by both companies' shareholders, and is expected to close in the third quarter of 2004.

After the close of the transaction, the company will be called "Lyondell Chemical Company" and will be headquartered in Houston, Texas. Dan F. Smith will continue as president and chief executive officer, and Dr. William T. Butler will continue as the independent chairman of the Lyondell Board of Directors. Two independent members of Millennium's current Board will join the Lyondell Board, effective at the time of the closing.

The transaction combines two U.S. chemical companies that are well positioned globally, with leading positions in propylene oxide and derivatives, titanium dioxide (TiO2) and acetyls. And, through their Equistar joint venture -- a major North American producer of ethylene, propylene, polyethylene and aromatics -- they have significant leverage to the petrochemical cycle, providing opportunity for the combined company's shareholders to take full advantage of the recovery in the petrochemical cycle. The combined company will operate in 16 countries and employ about 10,000 people worldwide.

"Since its creation in 1985, Lyondell has become a leading, global, integrated chemical company with world-scale assets and proprietary processes and technology," said Dan F. Smith, Lyondell's president and chief executive officer. "We have a long history of successfully combining assets, product lines and corporate cultures to create one of the world's leading chemical companies. Despite the prolonged industry trough, Lyondell and Equistar combined finished 2003 with more than $1.3 billion of liquidity. We expect this transaction to be accretive to Lyondell's earnings per share in 2005.

"This is another step in our long-standing strategy to increase Lyondell's global depth and breadth, and maintains our leverage to the ethylene cycle, allowing us to use the resulting cash flow to reduce debt," added Smith. "By integrating Millennium's operations with Lyondell's and Equistar's, we believe there is value that can be achieved through the realization of synergies. We expect to realize at least $50 million in cost savings from this combination, bringing value to all of the shareholders."

Robert E. Lee, president and chief executive officer of Millennium, said, "This is the right move at this juncture for Millennium. The transaction creates compelling value for our shareholders. We strongly believe that the added diversification and market leadership brought by the TiO2 and acetyls businesses will greatly benefit the combined entity. These businesses also will benefit from being part of a larger global entity."

Millennium is the second-largest producer of TiO2 in the world, in an industry in which the five largest producers represent approximately 75 percent of worldwide capacity. Millennium has a larger geographic footprint than any other TiO2 producer, with competitive production facilities on four continents. The TiO2 business has a strong technology and customer base.

The acetyls business is a significant ethylene consumer and, as such, integrates very well with Equistar's petrochemical business. Millennium holds the number-two North American capacity position for acetyls and is number three in the world. Millennium utilizes proprietary, advantaged technology at its world-scale manufacturing facility in La Porte, Texas.

"After the closing of the transaction, Lyondell will appear much less complicated to our investors with its consolidated petrochemicals, polymers and intermediate chemicals businesses. In the new organization, however, Lyondell, Equistar and Millennium will each remain separate entities and keep their separate debt structures," Smith said.

The transaction involves the merger of a newly created subsidiary of Millennium into Millennium, in which the Millennium common stock now held by its public shareholders will be converted into common stock of Lyondell, and the Millennium preferred stock to be issued to Lyondell immediately before the merger will be converted into common stock of the surviving entity. As a result, Millennium will become a wholly owned subsidiary of Lyondell. Following the transaction, the Millennium convertible debentures will become convertible into Lyondell common stock in accordance with the terms of the convertible debenture indenture.

Citigroup Global Markets Inc. acted as financial advisor and provided a fairness opinion to Lyondell. J.P. Morgan Securities Inc. acted as principal financial advisor to Millennium, and along with UBS Investment Bank, each has provided a fairness opinion to Millennium. Baker Botts L.L.P. is legal counsel to Lyondell, and Weil, Gotshal & Manges LLP is legal counsel to Millennium.

Lyondell, headquartered in Houston, Texas, is a leading producer of: propylene oxide (PO); PO derivatives including propylene glycol (PG), butanediol (BDO) and propylene glycol ethers (PGE); and styrene monomer and MTBE as co-products of PO production. Through its current 70.5 percent interest in Equistar Chemicals, LP, Lyondell also is one of the largest producers of ethylene, propylene and polyethylene in North America and a leading producer of ethylene oxide, ethylene glycol, high value-added specialty polymers and polymeric powder. Through its 58.75 percent interest in LYONDELL-CITGO Refining LP, Lyondell is one of the largest refiners in the United States processing extra heavy Venezuelan crude oil to produce gasoline, low sulfur diesel and jet fuel.

Millennium is the second-largest producer of TiO2 in the world, the largest merchant seller of titanium tetrachloride and a major producer of zircon and zirconia, silica gel and cadmium-based pigments. It also is the second-largest producer of acetic acid and vinyl acetate monomer in North America, and a leading producer of terpene-based fragrance and flavor chemicals. Millennium currently has a 29.5 percent interest in Equistar.
