        of the sole owner of Eagle Rock Energy G&P, LLC (the "Company"), which is
        the general partner of Eagle Rock Energy GP, L.P., which is the general partner
        of Eagle Rock.  Because of the potential conflict of interest between
        the interests of the Company and the public unitholders of Eagle Rock, the
        Board
        of Directors of the Company (the "Board") authorized the Company's Conflicts
        Committee to review, evaluate, and, if determined appropriate, approve the
        Stanolind Acquisition.  The Conflicts Committee, consisting of
        independent directors of the Board, determined that the Stanolind Acquisition
        was fair and reasonable to Eagle Rock and its public unitholders and recommended
        to the Board that the transaction be approved and
        authorized.
The
        foregoing description of the
        transaction does not purport to be complete and is qualified in its entirety
        by
