Explanation of Responses:
1. Exempt payment to Mr. Hohn of director's fees and/or annual retainer in the form of Common Stock of the Issuer pursuant to the CSX Corporation Stock Plan for Directors. Such shares of Common Stock are held for the benefit of The Children's Investment Master Fund.
2. Includes shares of Common Stock of the Issuer beneficially owned by The Children's Investment Master Fund, a Cayman Islands exempted company (the "TCI Fund"). The Children's Investment Fund Management (Cayman) Ltd., a Cayman Islands exempted company ("TCIF") and The Children's Investment Fund Management (UK) LLP, an English limited liability partnership ("TCIF UK") serve as management companies for the TCI Fund. Christopher Hohn is the managing partner of TCIF UK and the 100% owner of TCIF, and therefore is in a position to determine the investment and voting decisions made by the TCI Fund.
3. The Reporting Persons disclaim beneficial ownership of any and all securities reported herein in excess of their respective pecuniary interest therein and this report shall not be deemed an admission that the Reporting Persons are the beneficial owners of such securities for purposes of Section 16 or for any other purpose. Mr. Hohn is a director of the Issuer.
Remarks:
TCIF UK, TCIF and the TCI Fund may be deemed to be directors by deputization by virtue of the fact that Mr. Hohn, the managing partner of TCIF UK and the 100% owner of TCIF, serves on the board of directors of the Issuer.
