Union Pacific's revised proposal is subject, among other things, to termination of the Burlington Northern / Santa Fe merger agreement in accordance with its terms, negotiation of a mutually satisfactory merger agreement with Santa Fe in accordance with the terms of Santa Fe's existing merger agreement with Burlington Northern and approval of the respective Boards of Directors of Santa Fe and Union Pacific. A vote of stockholders of Santa Fe and Union Pacific is not required in order to consummate the cash tender offer. Approval of Santa Fe stockholders (but not Union Pacific stockholders) is required in order to consummate the second-step merger. The revised Union Pacific proposal is not subject to approval of the Interstate Commerce Commission (other than as referred to in footnote 3 above), a due diligence condition or financing. The Burlington Northern / Santa Fe merger agreement is subject to approval of the Interstate Commerce Commission and the respective stockholders of Burlington Northern and Santa Fe. Because of fluctuations in the market value of Union Pacific common stock and Burlington Northern common stock, there can be no assurances as to the actual value that Santa Fe stockholders would receive pursuant to the second-step merger contemplated by the revised Union Pacific proposal or the Santa Fe/Burlington Northern merger.

This solicitation is neither an offer to sell nor a solicitation of offers to buy any securities which may be issued in any merger or similar business combination involving Union Pacific and Santa Fe. The issuance of such securities would have to be registered under the Securities Act of 1933 and such securities would be offered only by means of a prospectus complying with the requirements of such Act.


1. Based on Union Pacific's closing market price on November 8, 1994 (the last trading day before Union Pacific's proposal was publicly announced), the value of the consideration in the second step merger would be equivalent to the tender offer price. Because of fluctuations in the market value of Union Pacific common stock, based on Union Pacific's closing market price on November 11, 1994, the value of the consideration in the second-step merger would be less than the tender offer price.

2. Santa Fe shareholders would not receive dividends with respect to shares which, pursuant to the Union Pacific proposal, would be acquired in the cash tender offer. The indicated annual dividend rate on a per share equivalent basis is determined by multiplying (i) the current annual dividend rate on shares of common stock of Union Pacific or Burlington Northern, as the case may be, by (ii) the applicable exchange ratio. There can be no assurance that Burlington Northern or Union Pacific will continue to pay dividends at rates currently in effect or will pay any dividend in the future.

3. Union Pacific is requesting the Staff of the Interstate Commerce Commission ("ICC") to provide an informal, non-binding opinion to the effect that the ICC approves the use of a Voting Trust by Union Pacific without the imposition of any conditions unacceptable to Union Pacific. Receipt of such opinion is a condition of Union Pacific's revised proposal and of the cash tender offer. Union Pacific believes it will obtain such approval from the Staff of the ICC.
