1 EXHIBIT 3 [DEKALB GENETICS CORPORATION LOGO] NEWS RELEASE David R. Wagley Vice President & Treasurer (815) 758-9383 FOR IMMEDIATE RELEASE MONDAY, MAY 11, 1998 DEKALB GENETICS AGREES TO MERGE WITH MONSANTO DEKALB, Illinois, May 11, 1998 - DEKALB Genetics Corporation said today that it has entered into an agreement with Monsanto Company by which Monsanto will acquire all of the shares of DEKALB capital stock that it does not already own. Monsanto, which currently owns 40 percent of DEKALB's outstanding shares, has agreed to pay a cash price of $100 for each of the remaining shares. The merger will be completed as soon as practicable. "The combination of DEKALB and Monsanto will create one of the leading seed germplasm and technology companies in the world," said Bruce P. Bickner, DEKALB's chairman and chief executive officer. "Ultimately, customers will be the beneficiaries. The full integration of DEKALB and Monsanto germplasm and technology will allow us to provide customers with rapid access to a broad range of value-added products." The Roberts family, which holds 56 percent of the outstanding Class A voting shares of DEKALB Genetics, has agreed to irrevocably tender its shares and vote for the merger, the company said. DEKALB's Class A shares represent approximately 13 percent of DEKALB's total outstanding common stock. In February 1998, the family said it supported the board of directors' decision to seek a possible business combination in order to maximize shareholder value. Under terms of the agreement, Monsanto has contracted to provide all DEKALB employees worldwide with continuing employment for at least one year after the closing. DEKALB has approximately 2,000 employees. "DEKALB shareholders will receive exceptional value for their investment in DEKALB and their faith in the company's management and employees," Bickner said. "Several years ago we announced our intent to be the 'success story of the '90s in the seed industry.' Today's transaction underscores just how successful we have been. "DEKALB has emerged as the fastest-growing agronomic seed company in the world, and our further affiliation with Monsanto will only accelerate our momentum," he added. "We are pleased and proud to be an integral part of Monsanto's growing worldwide seed team." 3100 SYCAMORE ROAD, DEKALB, IL 60115-9600 815-758-3461 FAX: 815-758-3711 2 DEKALB GENETICS CORPORATION ADD -1- At present, Monsanto holds 10 percent of DEKALB's outstanding 4.6 million Class A voting stock and 45 percent of the outstanding 30.0 million Class B non-voting stock.
