Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	The transaction reported on this Form 4 is solely the exercise of certain call options previously reported as acquired by the Reporting Persons.
(2)	These shares are owned by National Indemnity Company ("NICO"), a subsidiary of OBH, Inc. ("OBH"). OBH is a subsidiary of Berkshire Hathaway Inc. ("Berkshire"). Shares of Burlington Northern common stock previously held by two other subsidiaries of Berkshire, National Fire & Marine Insurance Company and Columbia Insurance Company, were transferred to NICO.
(3)	As OBH and Berkshire are each in the chain of ownership of NICO, each of Berkshire and OBH may be deemed presently to both beneficially own and have a pecuniary interest in all shares of Burlington Northern common stock presently owned by NICO. Warren E. Buffett, as the controlling stockholder of Berkshire, may be deemed presently to beneficially own, but only to the extent he has a pecuniary interest in, the shares of Burlington Northern common stock presently owned by NICO. Mr. Buffett disclaims beneficial ownership of the reported securities except to the extent of his pecuniary interest therein.
(4)	The call options were owned by NICO.
