"Exchange Act"), and, accordingly, each may be deemed to beneficially own the
shares of the Common Units beneficially owned by the others. Each of the Third
Point Reporting Persons disclaims beneficial ownership of the Common Units held
by the BLRTQS Reporting Persons and any pecuniary interest therein, and each of
the BLRTQS Reporting Persons disclaims beneficial ownership of the Common Units
held by the Third Point Reporting Persons and any pecuniary interest therein.
