These are our top ten: 1. LESS CASH FOR YOU. Union Pacific is offering cash for 100% of your Santa Fe shares. In sharp contrast, the Burlington Northern transaction provides cash for somewhat more than one-third of your Santa Fe shares - and most of those shares would be bought by Santa Fe itself. 2. UNCERTAIN VALUE. In a Union Pacific deal, you would receive $18.50 per share in cash for all your shares. Even if the Burlington Northern merger eventually occurs, your remaining shares would be exchanged up to several years from now for shares of Burlington Northern common stock. This delay creates uncertainty as to value. 3. IT COULD BE SOMETIME IN 1997 ... With Union Pacific's ICC-approved Voting Trust and financing already in place, we are positioned to purchase and pay for all Santa Fe shares within a few weeks of an executed Union Pacific/Santa Fe merger agreement. By contrast, Santa Fe already has experienced a delay in its ICC proceeding - and in talking about the Burlington Northern merger in its own proxy statement, Santa Fe says: "consummation of the Merger may not occur for two or more years in the future." 4. ... OR IT COULD NEVER HAPPEN AT ALL. With Union Pacific's Voting Trust you bear no risk at all of ICC approval. But the Burlington Northern merger is subject to ICC approval - and you bear the risk that such approval might never be obtained. 5. $900 MILLION OF NEW SANTA FE DEBT. Santa Fe says in its proxy statement that it "anticipates borrowing up to $1.31 billion (of which approximately $400 million will be to replace existing debt)" in connection with its repurchase of Santa Fe shares and related matters in the cash portion of the Burlington Northern transaction. 6. WHAT THIS DEBT MEANS TO YOU. Santa Fe goes on to say in its proxy statement that the "interest expense on [Santa Fe's] anticipated borrowings would reduce [Santa Fe's] net income" and that, although its Board believes the proposed borrowing is "prudent" - "it is possible that the need to repay the debt incurred in its borrowing will have a detrimental effect on [Santa Fe], either before the Merger or if the Merger cannot be consummated." Keep in mind that you'll continue to hold your remaining Santa Fe shares while you wait to see if the ICC approves the Burlington Northern merger. 7. LOSS OF DIVIDENDS. Here's what the Santa Fe proxy statement has to say about the impact of these new borrowings on your dividends: "[Santa Fe] currently does not plan to pay dividends for the foreseeable future if the [Santa Fe/Burlington Northern joint tender offer] is consummated." 8. UNION PACIFIC: READY, WILLING AND ABLE. Santa Fe's own Board has concluded: "... a strategic combination ... is required to protect and enhance shareholder value." If you reject the Burlington Northern merger, we believe Santa Fe's Board would be ready to deal with us in good faith. 9. THERE IS A WAY WE CAN ACT ON OUR OWN. We have told Santa Fe that we are prepared to use the Delaware short- form merger statute - and complete our tender offer without a merger agreement - if at least 90% of Santa Fe's shares are tendered and impediments such as the "poison pill" are eliminated. We would first need ICC approval to amend our Voting Trust in certain respects. 10. BURLINGTON NORTHERN DOESN'T DESERVE YOUR VOTE. In November, Union Pacific established a voting trust for your benefit so you would have no risk or delay in connection with ICC approval. Since then, Burlington Northern tried many times - each time unsuccessfully - to block ICC approval of our Voting Trust. We certainly don't think Burlington Northern was looking out for your best interests when they took those actions. THE FEBRUARY 7 VOTE ON THE BURLINGTON NORTHERN MERGER IS A SHORT TIME AWAY.
