Other Events. On September 14, 1998, a shareholder of Union Pacific Corporation (the "Company") filed a purported derivative action on behalf of the Company in the District Court for Tarrant County, Texas, captioned Stepak v. Lewis, Cause No. 342-175282-98 (District Court of Tarrant County, Texas), naming as defendants the Company, the Company's principal rail subsidiary, Union Pacific Railroad Company ("UPRR"), and the current and certain former directors of the Company. The derivative action alleges, among other things, that the named current and former directors breached their fiduciary duties to the Company by approving and implementing the merger of Southern Pacific Transportation Company and its affiliated railroads with UPRR without informing themselves of its impact or ensuring that adequate controls were put in place and by causing the Company to make misrepresentations about its service problems to the financial markets and regulatory authorities. The defendants believe that these claims are without merit and intend to defend them vigorously. Item 7. Financial Statements and Exhibits.
