SCHEDULE A

ENTERGY TEXAS, INC. LITIGATION

Recent Retail Rate Proceeding before the Public Utility Commission of Texas

Entergy Texas, Inc. (Entergy Texas) made a rate filing in September 2007 with
the Public Utility Commission of Texas (PUCT) requesting an annual rate increase
totaling $107.5 million, including a base increase of $64.3 million and special
riders totaling $43.2 million. The base rate increase includes $12.2 million for
the storm damage reserve. Entergy Texas is requesting an 11% return on common
equity. In December 2007 the PUCT issued an order setting September 26, 2008 as
the effective date for the rate change from the rate filing. Testimony filed by
the PUCT staff and intervenors generally asks for rates to be set lower than the
rates now being charged by Entergy Texas.
