CIGNA'S CAUTIONARY STATEMENT FOR PURPOSES OF THE "SAFE HARBOR” PROVISIONS OF THE PRIVATE SECURITIES LITIGATION REFORM ACT OF 1995

We have made forward-looking statements in this press release. Forward-looking statements may contain information about financial prospects, economic conditions, trends and other uncertainties. These forward-looking statements are based on management’s beliefs and assumptions and on information available to management at the time the statements are or were made. Forward-looking statements include, but are not limited to, that Cigna may sell shares of its common stock, the expected number of shares to be sold, the expected use of the net proceeds from the sales, that the managing underwriters may exercise their option to purchase additional shares from Cigna, the information concerning possible or assumed future business strategies, financing plans, and the pending acquisition of HealthSpring. Forward-looking statements include all statements that are not historical facts and can be identified by the use of forward-looking terminology such as the words "believe”, "expect”, "plan”, "intend”, "anticipate”, "estimate”, "predict”, "potential”, "may”, "should” or similar expressions.

By their nature, forward-looking statements: (i) speak only as of the date they are made, (ii) are not guarantees of future performance or results and (iii) are subject to risks, uncertainties and assumptions that are difficult to predict or quantify. Therefore, actual results could differ materially and adversely from those forward-looking statements as a result of a variety of factors. Some factors that could cause actual results to differ materially from the forward-looking statements include:

This list of important factors is not intended to be exhaustive. The "Risk Factors” section of the prospectus supplement filed in connection with the proposed offering of common stock of Cigna Corporation and other sections of our most recent Annual Report on Form 10-K for the year ended December 31, 2010, including the "Risk Factors” section therein, and other documents filed with the SEC include both expanded discussion of these factors and additional risk factors and uncertainties that could preclude Cigna from realizing the forward-looking statements. Cigna does not assume any obligation to update any forward-looking statements, whether as a result of new information, future events or otherwise, except as required by law.
