Cautionary Statements Regarding Forward-Looking Information

This communication may contain or incorporate by reference statements or information that are, include or are based on forward-looking statements within the meaning of the safe-harbor provisions of the Private Securities Litigation Reform Act of 1995. Forward-looking statements give expectations, intentions, beliefs or forecasts of future events or otherwise for the future, and can be identified by the fact that they relate to future actions, performance or results rather than relating strictly to historical or current facts. Words such as “believe(s),” “goal(s),” “target(s),” “estimate(s),” “anticipate(s),” “forecast(s),” “project(s),” “plan(s),” “intend(s),” “expect(s),” “might,” “may,” “could” and variations of such words and other words and expressions of similar meaning are intended to identify such forward-looking statements. However, the absence of such words or other words and expressions of similar meaning does not mean that a statement is not forward-looking.

Any or all forward-looking statements may turn out to be wrong, and, accordingly, readers are cautioned not to place undue reliance on such statements. Forward-looking statements involve a number of risks and uncertainties that are difficult to predict, and are not guarantees or assurances of future performance. No assurances can be given that the results and financial condition contemplated in any forward-looking statements will be achieved or will be achieved in any particular timetable. Forward-looking statements involve a number of risks and uncertainties that are difficult to predict, and can be affected by inaccurate assumptions or by known or unknown risks and uncertainties that may be important in determining actual future results and financial condition. The general factors that could cause actual results and financial condition to differ materially from those expressed or implied include, without limitation, the following: (a) the satisfaction or waiver of the conditions precedent to the consummation of the proposed merger transaction involving Kemper Corporation (the “Company”), a wholly-owned subsidiary of the Company and Infinity Property and Casualty Corporation (“Infinity”), including, without limitation, the receipt of stockholder and regulatory approvals (including approvals, authorizations and clearance by insurance regulators necessary to complete such proposed merger transaction) on the terms desired or anticipated (and the risk that such approvals may result in the imposition of conditions that could adversely affect the combined company or the expected benefits of such proposed merger transaction); (b) unanticipated difficulties or expenditures relating to such proposed merger transaction; (c) risks relating to the value of the shares of the Company’s common stock to be issued in such proposed merger transaction; (d) disruptions of the Company’s and Infinity’s current plans, operations and relationships with third persons caused by the announcement and pendency of such proposed merger transaction, including, without limitation, the ability of the combined company to hire and retain any personnel; (e) legal proceedings that may be instituted against the Company and Infinity in connection with such proposed merger transaction; and (f) those factors listed in annual, quarterly and periodic reports filed by the Company and Infinity with the Securities and Exchange Commission (the “SEC”), whether or not related to such proposed merger transaction.

The Company assumes no, and expressly disclaims any, duty or obligation to update or correct any forward-looking statement as a result of events, changes, effects, states of facts, conditions, circumstances, occurrences or developments subsequent to the date of this communication or otherwise, except as required by law. Readers are advised, however, to consult any further disclosures the Company makes on related subjects in its filings with the SEC.
