Union Pacific Announces 2-For-1 Stock Split, Additional Share Repurchase Authorization and Second Quarter Dividend

Omaha, Neb., May 01, 2008 – Union Pacific Corporation (NYSE:UNP) announced that its Board of Directors voted today to authorize a two-for-one stock split, distributed as a stock dividend.  Shareholders will receive one additional share of Union Pacific common stock for each common share held.  The stock dividend will be paid on May 28, 2008, to shareholders of record on May 12, 2008.  This action will not change the proportionate interest that a shareholder maintains in the company. 

Separately, the Board of Directors also authorized the repurchase of 20 million common shares (40 million shares post-split) by March 31, 2011.  This new authorization is in addition to the 20 million share repurchase program initiated in January 2007.  Since last January, Union Pacific has repurchased 16 million shares of common stock, returning $1.9 billion to shareholders.  Approximately 4 million shares (8 million shares post-split) remain to be repurchased under the prior authorization.  When completed, these two repurchase authorizations will have reduced total shares outstanding by roughly 15 percent since the start of the first program.  The timing and volume of share repurchases under these authorizations will be at the discretion of management.  Any share repurchase under these programs may be made in the open market, or otherwise. 

Today, the Board of Directors also declared a quarterly dividend of 44 cents per common share (22 cents per share post-split) for the second quarter of 2008.  The dividend is payable on July 1, 2008, to shareholders of record May 30, 2008.  Union Pacific has paid dividends on its common stock for 109 consecutive years.

"We remain committed to improving returns," said Jim Young, Chairman and Chief Executive Officer.  "Union Pacific is building a strong track record of delivering results for its shareholders.  The actions we are taking today reflect our confidence in the bright future of our Company.  Our strong financial performance will enable us to continue to invest for safety and growth, maintain a strong balance sheet and enhance shareholder value."
