As provided by the safe harbor provisions of the Private Securities Litigation Reform Act of 1995, NL cautions that statements in this Form 12b-25 relating to matters that are not historical facts including, but not limited to, statements found in this Part IV - "Other Information," are forward-looking statements that represent management's beliefs and assumptions based on currently available information. Forward-looking statements can be identified by the use of words such as "believes," "intends," "may," "will," "should," "could," "anticipates," "expects," or comparable terminology or by discussions of strategy or trends. Although NL believes that the expectations reflected in such forward-looking statements are reasonable, it cannot give any assurances that these expectations will prove to be correct. Such statements by their nature involve risks and uncertainties. Should one or more of these risks materialize (or the consequences of such a development worsen), or should the underlying assumptions prove incorrect, actual results could differ materially from those forecasted or expected. NL disclaims any intention or obligation to update publicly or revise such statements whether as a result of new information, future events or otherwise.
