EXHIBIT (A)(2) - -------------------------------------------------------------------------------- LOGO UNION TEXAS PETROLEUM NEWS RELEASE - -------------------------------------------------------------------------------- FOR IMMEDIATE RELEASE May 4, 1998 ARCO ANNOUNCES MERGER AGREEMENT WITH UNION TEXAS PETROLEUM $3.3 BILLION DEAL SUBSTANTIALLY INCREASES ARCO'S INTERNATIONAL PRODUCTION AND RESERVES KKR, CONTROLLING 25.6% OF UNION TEXAS STOCK, SIGNS COMMITMENT TO TENDER UNION TEXAS INTEREST TO ARCO LOS ANGELES AND HOUSTON - ARCO (NYSE: ARC) and Union Texas Petroleum (NYSE: UTH) announced today that they have signed a definitive merger agreement under which ARCO will acquire for cash all outstanding shares of Union Texas common stock for $29 per share in a transaction valued at approximately $3.3 billion, including debt and preferred stock of Union Texas. The agreement was approved unanimously by the Boards of Directors of both companies. In connection with the transaction, ARCO has obtained a commitment from Kohlberg Kravis Roberts & Co. to tender its holdings of 25.6 percent of the outstanding Union Texas common shares pursuant to the tender offer. ARCO Chairman and Chief Executive Officer Mike R. Bowlin called the agreement "an important building block" for the company. "This acquisition is consistent with our strategy of building scale and presence in 5 to 6 core producing areas as a means of creating shareholder value," Bowlin added. "Over 90 percent of Union Texas' assets are located in ARCO's core producing areas, specifically Venezuela, Indonesia, the North Sea and Alaska. The combination of the two companies solidifies ARCO's position as a significant player in those regions and is another step toward accomplishing our goal of becoming a great global player." Bowlin noted that "the transaction is especially attractive to ARCO because of the exceptional degree of overlap between the assets of the two companies and the ability to implement significant cost reductions as a consequence." Bowlin said he expects the combination to eventually yield after- tax cost savings of at least $85 million per year. The transaction will immediately add 140,000 barrels per day of oil equivalent (BOE) to ARCO's production. Union Texas expects strong production growth over the near term from assets such as the Britannia field in the North Sea, the Boqueron and DZO concessions in Venezuela, and the Alpine field in Alaska. The transaction will also add 573 million barrels of proved reserves for a gross cost of $5.76 per BOE. ARCO estimates it is paying approximately $5 per proved BOE based on costs attributable to producing oil and gas assets. In addition, probable and possible reserves also have been identified for future development. "In addition to strengthening our core areas," Bowlin noted, "Union Texas offers several new venture options to ARCO, ranging from its long- established operations in Pakistan to its growing position in Kazakhstan and Azerbaijan in the Caspian region. Finally, Union Texas' long-term experience in Indonesia's LNG business should prove valuable as we continue development and marketing of ARCO's Tangguh gas reserves discovered last year." John Whitmire, Chairman and Chief Executive Officer of Union Texas, said that "ARCO's tender offer reflects the proven value and potential of Union Texas Petroleum. Over the past two years, Union Texas' management team and our employees around the world have made significant progress in creating exciting growth prospects for our company in areas such as Venezuela, Kazakhstan, China and Northern Africa. I believe it was Union Texas' growth performance that attracted ARCO to our organization." Bowlin said he expects the acquisition to be accretive to operating cash flow in the first year and only modestly dilutive to earnings through next year. He noted that there is little downside risk in this transaction as Union Texas' production from known resources is rising and the cost reductions anticipated are totally within ARCO's control. ARCO expects the tender offer will be completed by the end of the company's second quarter. ARCO plans to finance the transaction using commercial paper and other short-term borrowings backed by existing and additional bank facilities. Under the terms of the merger agreement, ARCO will commence an all-cash tender offer for all of Union Texas' outstanding common stock on or prior to May 8, 1998. Any shares not purchased in the tender offer will be acquired for $29 per share in cash pursuant to a merger after completion of the tender offer. As of March 31, 1998, Union Texas had approximately 85.25 million shares outstanding. The transaction is subject to usual closing conditions, including regulatory approvals. Union Texas Petroleum is a Houston-based oil and gas company with 1997 sales of $909 million and assets of $2.0 billion. In addition to its Caspian Sea exploration projects and major operations in Indonesia, the North Sea and Venezuela, the company also has operations in Pakistan, where it produces approximately 45 percent of the country domestic oil output.
