 This presentation may contain forward-looking statements within the meaning of the Private Securities Litigation Reform
 Act of 1995. These statements relate to future events or DLH`s future financial performance. Any statements that are not
 statements of historical fact (including without limitation statements to the effect that the Company or its management
 "believes", "expects", "anticipates", "plans", “intends” and similar expressions) should be considered forward looking
 statements that involve risks and uncertainties which could cause actual events or DLH`s actual results to differ
 materially from those indicated by the forward-looking statements. For a discussion of such risks and uncertainties, see
 “Risk Factors” in the company’s periodic reports filed with the SEC, including our Annual Report on Form 10-K for the
 fiscal year ended September 30, 2015. In light of the risks and uncertainties inherent in the forward-looking statements
 included herein, the inclusion of such statements should not be regarded as a representation by the Company or any

 results and believes that this information may be informative to investors in gauging the quality of our financial
 performance, identifying trends in our results, and providing meaningful period-to-period comparisons. These measures
