DEREGISTRATION OF SECURITIES

This Post-Effective Amendment (this “Post-Effective Amendment”) relates to the following Registration Statements of HealthSpring, Inc. (the “Company”) on Form S-8 (collectively, the “Registration Statements”):

Registration Statement No. 333-167235, registering 3,250,000 shares of the Company’s common stock, par value $0.01 (“Company common stock”), under the HealthSpring, Inc. Amended and Restated 2006 Equity Incentive Plan;

Registration Statement No. 333-151163, registering 500,000 shares of Company common stock, under the HealthSpring, Inc. 2008 Management Stock Purchase Plan; and

Registration Statement No. 333-131654, registering 6,445,000 shares of Company common stock, under the HealthSpring, Inc. 2006 Equity Incentive Plan and the NewQuest Holdings, Inc. 2005 Stock Option Plan.

On January 31, 2012, the Company completed the merger contemplated by the Agreement and Plan of Merger (the “Merger Agreement”), dated as of October 24, 2011, among the Company, Cigna Corporation, a Delaware corporation (“Cigna”), and Cigna Magnolia Corp., a Delaware corporation and an indirect, wholly owned subsidiary of Cigna (“Merger Sub”). Pursuant to the Merger Agreement, the Company was acquired by Cigna through a merger of Merger Sub with and into the Company (the “Merger”), with the Company surviving the Merger as an indirect, wholly-owned subsidiary of Cigna. At the effective time of the Merger, (i) each outstanding share of Company common stock, other than restricted shares, treasury shares, shares owned by the Company, Cigna, Merger Sub, or any of their wholly-owned subsidiaries, and shares for which appraisal was properly demanded, was converted into the right to receive $55.00 in cash, without interest and subject to any applicable withholding taxes, and (ii) equity awards relating to Company common stock were treated in accordance with the Merger Agreement and agreements entered into in connection with the Merger.

As a result of the Merger, the Company has terminated any and all offerings of securities pursuant to the Registration Statements. Accordingly, the Company hereby terminates the effectiveness of each Registration Statement and, in accordance with an undertaking made by the Company in Part II of each Registration Statement to remove from registration, by means of a post-effective amendment, any securities that had been registered for issuance but remain unsold at the termination of the offering, removes from registration any and all securities registered but unsold under the Registration Statements as of the date hereof.
