To: Brokers, Dealers, Commercial Banks, Trust Companies and Other Nominees:
Norfolk Southern Corporation (the "Corporation") is offering, upon and subject to the terms and conditions set forth in the prospectus dated , 2004 (the "Prospectus"), and the enclosed letter of transmittal (the "Letter of Transmittal"), to holders of our outstanding 7.35% Notes Due May 15, 2007 (the "old notes"), an opportunity to exchange into new notes due September 1, 2014 (the "new notes"), in an aggregate principal amount to be determined in the manner set forth in the Prospectus (the "Exchange Offer").
We want to encourage holders to tender early. Accordingly, the total exchange price, for each $1,000 principal amount of old notes tendered and accepted, includes an early participation payment of $ (the "early participation payment"). Holders who validly tender their old notes on or prior to 5:00 p.m. New York City time on the early participation date and do not withdraw their tenders will receive the early participation payment. Holders who validly tender their old notes after the early participation date and do not withdraw their tenders will not receive the portion of the total exchange price attributable to the early participation payment.
New notes will be issued in minimum denominations of $1,000 and integral multiples of $1,000. If, under the terms of the Exchange Offer, any tendering holder is entitled to receive new notes in a principal amount that is not an integral multiple of $1,000, we will round downward the amount of new notes to the nearest integral multiple of $1,000 and pay the difference in cash.
Assuming we have not previously elected to terminate the Exchange Offer, for any or no reason, in our sole and absolute discretion and subject to the conditions listed below, we will exchange up to $400,000,000 aggregate principal amount of the old notes for new notes, subject to the requirement that we receive valid tenders, not withdrawn prior to the expiration date, of at least $150,000,000 aggregate principal amount of old notes. If old notes having an aggregate principal amount of more than $400,000,000 are validly tendered and not withdrawn, the Corporation will accept for exchange only old notes in an aggregate principal amount up to $400,000,000 aggregate principal amount of old notes on a pro rata basis among the tendering holders.
We are requesting that you contact your clients for whom you hold old notes regarding the Exchange Offer. For your information and for forwarding to your clients for whom you hold old notes registered in your name or in the name of your nominee, or who hold old notes registered in their own names, we are enclosing the following documents:
