Berkshire Hathaway Inc. and
Burlington Northern Santa Fe Corporation said they have been granted early
termination of the mandatory waiting period under the Hart-Scott-Rodino
Antitrust Improvement Act of 1976, as amended, in connection with the
previously announced Berkshire acquisition of BNSF. This regulatory action is
an important step in satisfying the closing conditions as set forth in the
merger agreement. BNSF and Berkshire continue to expect the transaction to
close in the first quarter of 2010.
