This presentation contains certain statements that are considered “forward-looking statements”

within the meaning of the Private Securities Litigation Reform Act of 1995. Forward-looking

statements generally can be identified by the use of forward-looking terminology such as “may,”

“will,” “expect,” “intend,” “estimate,” “anticipate,” “believe,” “project,” or “continue” or similar words

or the negative thereof. These statements do not relate to strictly historical or current facts and

provide current expectations of forecasts of future events. Any such expectations or forecasts of

future events are subject to a variety of factors. We caution that forward-looking statements must

be considered carefully and that actual results may differ in material ways due to risks and

uncertainties both known and unknown. Information about factors that could materially affect our

results can be found in Part I, Item 1A, Risk Factors in our Annual Report on Form 10-K for the

year ended December 31, 2014, and in Part II, Item 1A Risk Factors in our most recent quarterly

report on Form 10-Q. Shareholders and potential investors are urged to consider these factors in

evaluating forward-looking statements and are cautioned not to place undue reliance on such

forward-looking statements.

We undertake no obligation to update or revise any forward-looking statement, whether as a result

of new information, future events or otherwise. Investors are advised to consult any further

disclosures by us in our filings with the Securities and Exchange Commission and in other written

statements on related subjects. It is not possible to anticipate or foresee all risk factors, and

investors should not consider any list of such factors to be an exhaustive or complete list of all

risks or uncertainties.
