none of ATB Holdings Inc., EXM LLC, New EXM Inc., Marathon Oil Corporation,

nor any other  person is an  Acquiring  Person  (as  defined  in the Rights
Agreement) by reason of the execution and delivery of the Master  Agreement
or any other Transaction Agreement or the consummation of the Transactions,
(y) neither a Distribution Date nor a Business Combination (each as defined
in the  Rights  Agreement)  shall  occur by  reason  of the  execution  and
delivery of the Master Agreement or any other Transaction  Agreement or the
consummation of the  Transactions  and (z) New EXM Inc. will be substituted
for  Ashland at the  Conversion  Merger  Effective  Time (as defined in the
Master  Agreement)  and the Rights  Agreement will continue in effect after
such time.
