Filed by Anadarko Petroleum Corporation Pursuant to Rule 425 under the Securities Act of 1933 and deemed filed pursuant to Rule 14a-12 of the Securities Exchange Act of 1934 Subject Company: Union Pacific Resources Group Inc. Commission File No. 1-13916 ANADARKO TO MERGE WITH UNION PACIFIC RESOURCES GROUP THE NEW ANADARKO WILL HAVE BROADER GROWTH PORTFOLIO AND MORE FINANCIAL STRENGTH HOUSTON AND FORT WORTH, TEXAS, APRIL 3, 2000 -- Anadarko Petroleum Corporation (NYSE:APC) and Union Pacific Resources Group Inc. (NYSE:UPR) today announced a merger that will create one of the largest independent exploration and production companies in the world in terms of 1999 reserves, production and drilling activity. The combined company will be called Anadarko Petroleum Corporation and will be headquartered in Houston. Under the agreement, which was unanimously approved by each company's board of directors, UPR shareholders will receive 0.4550 Anadarko common shares for each UPR common share they own. As a result, Anadarko shareholders will hold approximately 53 percent of the combined company and UPR shareholders approximately 47 percent. Based on the Anadarko closing price of 38.6875 on March 31, 2000, the combined company will have about 243 million shares outstanding and a market capitalization over $9 billion. Based on this closing price, the transaction has an implied value to UPR shareholders of $17.60 per share, representing a 21% premium to UPR's closing price on Friday, March 31, 2000. The stock-for-stock deal is subject to approval by shareholders of both UPR and Anadarko and customary regulatory approval. Following the merger, UPR will be a wholly owned subsidiary of Anadarko. Anadarko expects the merger to be treated as a tax-free reorganization and accounted for as a purchase. The merger agreement includes a provision under which UPR and Anadarko granted each other the right to purchase 19.9% of each other's outstanding shares. Anadarko believes the proposed merger will be immediately accretive to both cash flow and earnings. # more # 1 Robert J. Allison, Jr. will continue to be Chairman and Chief Executive Officer of Anadarko. George Lindahl III, Chairman, President and Chief Executive Officer of UPR, will become Vice Chairman of Anadarko after the merger. Five members of UPR's Board of Directors will join the Anadarko board, subject to Anadarko shareholder approval of the larger board. Comments by Bob Allison: "This merger is an excellent fit for both companies. We blend Anadarko's strengths in exploration with what UPR does best - profitable exploitation with industry-leading drilling and completion technology. The new Anadarko will have the financial strength to aggressively pursue a broader portfolio of projects. We can accelerate activity in the most prospective areas offering the best returns for shareholders. We do expect some modest cost reductions with the merger, but that's not what drives this deal. It's about complementary skills and assets that can give us dramatic growth and profitability. We expect to grow faster and beyond the levels either company could achieve individually. Given the current outlook for energy markets, now is the time to step up the pace of drilling for new energy reserves -- particularly North American natural gas. More energy for America is good news for our shareholders and it's good news for consumers as well." Comments by George Lindahl: "The merger provides significant benefits to UPR shareholders. It recognizes the value of our core producing assets and our portfolio of projects throughout the Americas. We bring to the new Anadarko skills and experience that are complementary to their exploration strength. UPR is an industry leader in drilling and completion technology. That expertise can now be applied to a larger asset base with stronger capital resources than ever before. This deal offers UPR's shareholders an exciting future - marked by significant increases in production, earnings and cash flow - starting this year. We will have more exposure to high-potential exploration and increased opportunity for growth in the near-term. The combined companies share a commitment to organic growth through exploration and exploitation strategies that will continue to build value for shareholders in the future." # more # 2 Comments by Anadarko President and Chief Operating Officer John Seitz: "Anadarko has spent years developing what I believe to be the best team of energy explorers in the business and providing them the best available technology. Our team has delivered consistent growth in production and reserves and found a dozen giant oil and gas fields over the past 20 years. In recent years, our team has identified more outstanding drilling opportunities than we could fund with available cash flows. This merger gives us more capital and talented people, so we can immediately go to work finding new reserves of oil and gas. With the best people in the business, we expect to generate even more impressive growth and returns for our shareholders!" Anadarko said the company's Growth Portfolio would be well balanced around three types of worldwide activity -- Exploration, Development and Exploitation. The new Company would also have more Financial Strength than was previously offered by either company alone. GROWTH PORTFOLIO ---------------- Proved Reserves -- The combined companies' proved reserves would be equally split between crude oil and natural gas and equivalent to 1.94 billion barrels of oil (BOE) or about 11.65 Trillion cubic feet of gas (Tcfe). About 80 percent of total reserves are in North America and 20 percent in international areas. At current expected production rates, the reserve life index of the combined companies would be 10.8 years. Exploration -- The merger combines exploration projects now underway in both companies in some of the highest potential areas of the world today. To date, Anadarko has identified over 100 exploration prospects from the combined companies' portfolio with over 11 billion barrels of net un-risked reserve potential. In the U.S., significant reserve potential exists in a number of exploration plays in Texas, the Gulf of Mexico (conventional, sub-salt and deepwater plays), Alaska and the Rocky Mountain areas. In foreign exploration, the new portfolio will include projects in Canada, the Sahara Desert of Tunisia, the North Atlantic Margin, and Latin America. The new Anadarko will now have the financial strength to aggressively pursue additional exploration ventures worldwide. # more # 3 Development -- Near-term cash flow will benefit from a broad portfolio of development projects. Construction and development drilling are already underway to commercialize recently discovered oil and gas fields in Alaska (Alpine & Moquawkie fields), Algeria (the HBN and HBNS fields) and the Gulf of Mexico (Tanzanite & Hickory fields). In addition, large development drilling projects are planned to increase oil and gas production in Texas (the Carthage, Ozona and Giddings Fields); in Wyoming (the Wamsutter Field); and in Canada (the Hatton and Jedney fields). In 2001, these development projects should generate over 10 million BOE of new production with even higher levels in 2002. Exploitation -- Significant growth opportunity has been identified in existing fields, where in-fill and step-out drilling, state-of-the-art technologies in reservoir engineering, drilling, completion and production can be used to extend field limits, increase production and recover more reserves. Many projects represent a blend of exploration and development such as the Bossier Play in East Texas. To date, Anadarko has identified over 50 such projects in the inventory of the combined company. Net potential reserves from these projects are one billion BOE (un-risked). The new company will play a major role in the growing North American natural gas market.(1) Based on 1999 data for all energy companies (independents and majors), Anadarko will now rank as the 6th largest natural gas producer in North America, and the 5th largest holder of natural gas reserves. (See Attachments). The new Anadarko will hold significant acreage positions and drilling opportunity in most of the high-potential, gas-rich basins of North America, including Western Canada, and the U.S. basins of the Rocky Mountains, the Mid-continent, Texas, and the Gulf of Mexico. These basins today account for 90% of U.S. gas supply. # more # - ------------ (1) A 1999 study by the National Petroleum Council predicted US natural gas consumption would grow from 22 Tcf in 1998 to 26 Tcf in 2005 and reach 31 Tcf in 2015. 4 FINANCIAL STRENGTH ------------------- Earnings and Cash Flow -- Anadarko believes the proposed merger will be immediately accretive to both cash flow and earnings. Anadarko estimates that if the companies were combined for the year 2000, cash flow would have been about $1.8 billion (or about $7.50 per share). For the year 2001, given the current outlook for commodity prices, cash flow is expected to increase further, to more than $2 billion (or about $9.00 per share). Balance Sheet - The new Anadarko will have a stronger balance sheet than either company had individually. This increased financial strength should give the new Anadarko continued access to capital markets to continue its drilling and development projects around the world. Anadarko will utilize full-cost accounting for the combined company. On a pro-forma consolidated basis as of year-end 1999, the combined companies would have had a total capitalization of $10 billion, comprised of $5.9 billion of equity and $4.1 billion of debt. The debt to total capitalization ratio would be 41%. The average maturity life of the debt would be 21 years, and the average annual interest rate would be 7.11%. Credit Suisse First Boston and Wachtell, Lipton, Rosen & Katz served as advisors to Anadarko for this transaction. Advisors to UPR were the firms of Simmons and Company, Goldman Sachs, and Morgan, Lewis and Bockius.
