USPCI Inc., an Oklahoma City hazardous waste management company, has accepted a sweetened $28-a-share buyout offer from Union Pacific Corp., the companies have announced. Union Pacific, the New York-based rail and energy company, also said that if the merger was completed, it intended to negotiate for the possible acquisition of Beard Co., an Oklahoma City-based oil and gas company, which holds a 28% stake in USPCI. USPCI agreed to the buyout after rejecting two previous offers last month and earlier this year.
