MISO Statement Regarding Entergy and ITC Transaction

CARMEL, Ind., Dec. 6, 2011 /PRNewswire/ — In response to yesterday’s
announcement that Entergy Corp. (NYSE: ETR) plans to divest and merge its
electric transmission business into ITC Holdings Corp (NYSE: ITC), MISO today
issued the following statement:

MISO and Entergy continue to work jointly toward Entergy’s December 2013
integration into MISO. We are pleased that Entergy CEO, J. Wayne Leonard,
publicly reaffirmed Entergy’s commitment to MISO membership and the value that
it provides to consumers in the Entergy region. We are also pleased that Joseph
Welch, CEO of ITC, has offered to assist Entergy with its transition to MISO,
given ITC’s experience at MISO.

MISO currently supports a range of transmission ownership structures that allow
MISO’s mature, competitive wholesale energy market and scale of operations to
deliver increased consumer benefits and energy reliability. MISO is quite
familiar with ITC given that it already has significant operations in our
region.

Maintaining our current timetable for integration of Entergy’s transmission
assets is critical to enabling the benefits of MISO membership to flow to
electric customers in the Entergy region as soon as possible.
