Page 1 of 18 Forward Looking Statements

This presentation contains “forward-looking statements.” All statements other than statements of historical fact are, or may be deemed to be, forward-looking statements. Forward-looking statements include statements about the benefits of the split-off, the discussions of KBR’s business strategies and KBR’s expectations concerning future operations, profitability, liquidity and capital resources. You can generally identify forward- looking statements by terminology such as “anticipate,” “believe,” “continue,” “could,” “estimate,” “expect,” “forecast,” “goal,” “intend,” “may,” “objective,” “plan,” “potential,” “predict,” “projection,” “should” or other similar words. These statements relate to future events or future financial performance and involve known and unknown risks, uncertainties and other factors that may cause actual results, levels of activity, performance or achievements to differ materially from those in the future that are implied by these forward-looking statements. Many of these factors cannot be controlled or predicted. These risks and other factors include those described under “Risk Factors” in KBR’s Annual Report on Form 10-K dated February 25, 2010, Forms 10-Q, recent Current Reports on Forms 8-K, and other Securities and Exchange Commission filings. Those factors, among others, could cause KBR’s actual results and performance to differ materially from the results and performance projected in, or implied by, the forward-looking statements. As you read and consider this presentation, you should carefully understand that the forward-looking statements are not guarantees of performance or results. KBR cautions you that assumptions, beliefs, expectations, intentions and projections about future events may and often do vary materially from actual results. Therefore, KBR cannot assure you that actual results will not differ materially from those expressed or implied by forward-looking statements.

The forward-looking statements included in this presentation are made only as of the date of this document. New risks and uncertainties arise from time to time, and KBR cannot predict those events or their impact. KBR assumes no obligation to update any forward-looking statements after the date of this presentation as a result of new information, future events or developments, except as required by the federal securities laws.
