notwithstanding, the transfer of title to or interest in each such portion of the Wamsutter Assets
(herein called the &#147;<U><I>Restriction Asset</I></U>&#148;) pursuant to this Agreement shall not become
effective unless and until such Restriction is satisfied, waived or no longer applies. When and if
such a Restriction is so satisfied, waived or no longer applies, to the extent permitted by
applicable law and any applicable contractual provisions, the assignment of the Restriction Asset

to whom such Restriction Asset was intended to be conveyed and to otherwise use its reasonable
efforts to provide such other party with the benefits thereof, and the party holding such
Restriction Asset will enter into other agreements, or take such other action as it may deem
necessary, in order to ensure that the applicable party to whom such Restriction Asset was intended
to be conveyed has the assets and concomitant rights necessary to enable the applicable party to
operate such Restriction Asset in all material respects as it was operated prior to the date
hereof.
