FORWARD-LOOKING STATEMENTS

         Some of the statements in this report and the exhibits hereto are
"forward-looking statements" within the meaning of the Private Securities
Litigation Reform Act of 1995. In some cases, you can identify forward-looking
statements by the words "anticipates," "believes," "continue," "could,"

"plans," "potential," "predicts," "projection," "should," "will," or other
similar words.

         Texas Genco has based its forward-looking statements on its
management's beliefs and assumptions based on information available at the time
the statements are made. Texas Genco cautions you that assumptions, beliefs,
expectations, intentions and projections about future events may and often do
vary materially from actual results. Therefore, actual results may differ
materially from those expressed or implied by Texas Genco's forward-looking
statements. You should not place undue reliance on forward-looking statements.

statement, and Texas Genco undertakes no obligation to update or revise publicly
any forward-looking statements.
