(Amended and Restated Effective January 1, 2008)

ARTICLE 1

Statement of Purpose; Effect on Prior Plans

The CIGNA Restricted Share Equivalent Plan for Non-Employee Directors (Amended and Restated Effective January 1, 2008) (“Plan”) is an amendment and restatement of the Restricted Stock/Stock Equivalent Plan for Non-Employee Directors of CIGNA Corporation (“Former Plan”).

The Company granted restricted shares of Company Common Stock under the Former Plan from September 30, 1989 to September 30, 2004, and Restricted Share Equivalents (described in Article 3) from October 1, 2004 to January 1, 2006.  No grants of any kind were made under the Former Plan after January 1, 2006. The Former Plan was closed to new participants effective January 17, 2006.

This Plan applies only to Restricted Share Equivalents granted under the Former Plan between October 1, 2004 and January 1, 2006.  No grants will be made under this Plan.  The purpose of this amendment and restatement is to comply with Section 409A of the Internal Revenue Code and to delete now-obsolete Plan provisions.

ARTICLE 3

Restricted Share Equivalents

3.01        Eligibility and Grant.   Each director who became an Eligible Director after October 1, 2004 but before January 17, 2006 received a grant of 4,500 Restricted Share Equivalents, effective as of the date the director became an Eligible Director.  All outstanding Restricted Share Equivalents were adjusted to reflect a three-for-one stock split on June 4, 2007, so that Eligible Directors with outstanding grants had 13,500 Restricted Share Equivalents as of the split effective date.

3.02        General.  The Company maintains an account on its books and records to record the number of Restricted Share Equivalents granted by the Company to Eligible Directors.  Subject to the provisions of Section 3.04 below, the restrictions set forth in Section 3.03 shall apply to each grant of Restricted Share Equivalents.  An Eligible Director’s right to receive plan payments represents an unsecured claim against CIGNA Corporation’s general assets.

3.03        Restrictions on Restricted Share Equivalents.  The following restrictions apply to Restricted Share Equivalents:

3

(a)                                 Except as otherwise provided in Section 3.06, the Eligible Director shall not be entitled to the payment of the Restricted Share Equivalents until the date provided in Section 3.05;

(b)                                 None of the Restricted Share Equivalents may be sold, transferred, assigned, pledged, or otherwise encumbered or disposed of; and

(c)                                  All of the Restricted Share Equivalents shall be forfeited, and all rights of the Eligible Director to such Restricted Share Equivalents shall terminate without further obligation on the part of the Company, upon the Eligible Director’s ceasing to be a director of the Company before the date the Restricted Share Equivalents vest.

3.04  Vesting of Restricted Share Equivalents.

(a)                                 The Restricted Share Equivalents granted to an Eligible Director shall vest on the later of:

(1)                                 Six months after the date of grant; or

(2)                                 The earliest of:

(A)                               The Eligible Director’s ninth anniversary of continuous service as a director of the Company;

(B)                               The Eligible Director’s attainment of age 65;

(C)                               The Eligible Director’s Disability;

(D)                               The Eligible Director’s death; or

(E)                                The occurrence of a Change of Control.

(b)                                 If an Eligible Director’s resignation is accepted because he or she failed to receive the required majority vote for reelection and his or her Restricted Share Equivalents have not yet vested pursuant to Section 3.04(a), then a pro-rated portion of the Eligible Director’s Restricted Share Equivalents shall automatically vest effective as of the date of such resignation, with the portion to vest determined by multiplying 13,500 (adjusted as needed after June 4, 2007 in accordance with Section 4.01) by the following fraction: the number of complete months the Eligible Director performed continuous service as a director of the Company divided by 108.  Any resulting fractional Restricted Share Equivalent shall be eliminated.

(c)                                  If an Eligible Director ceases to be a director of the Company before the vesting of Restricted Share Equivalents pursuant to Section 3.04(a) or (b), the Eligible Director shall immediately forfeit all unvested Restricted Share Equivalents, except to the extent a majority of the other members of the Board approves their vesting.

3.05        Payment of Vested Restricted Share Equivalents. The cash value of the vested Restricted Share Equivalents shall be determined as of the date of an Eligible Director’s Separation from Service by using the closing price on that date as reported on the Composite tape or successor means of publishing stock prices (or, if the Composite tape or successor publication is not published on the date of Separation from Service, the closing price for the next preceding date of publication).  The Company shall pay the resulting cash value in a lump sum to the Eligible Director (or the Eligible Director’s beneficiary or estate, as the case may be) within 45 days of the Eligible Director’s Separation from Service.

4

Notwithstanding the foregoing, if an Eligible Director is a specified employee within the meaning of Treas. Reg. sec. 1.409A-1(i) as of the date of Separation from Service, payment shall be made in a lump sum in the seventh month following Separation from Service. Restricted Share Equivalents will cease to be outstanding and an Eligible Director will cease to have any rights under them as of the date they are paid or forfeited.

3.06        Hypothetical Dividends.  Each year that a Restricted Share Equivalent is outstanding, a lump sum payment shall be made to the Eligible Director in an amount equal to any dividends declared and paid on one share of Company Common Stock in that year (to the extent the record date for any such actual dividend occurs while the Restricted Share Equivalent is outstanding).

Article 4

Miscellaneous

4.01        Adjustment in Event of Changes in Capitalization.  In the event of a combination or exchange of shares, merger, consolidation, rights offering, separation, reorganization or liquidation, or any other change in the corporate structure of the Company, the Board may make such equitable adjustments, to prevent dilution or enlargement of rights, as it may deem appropriate in the number of Restricted Share Equivalents.  Outstanding Restricted Share Equivalents shall be adjusted proportionally to reflect any recapitalization, stock split or stock dividend.  Any additional Restricted Share Equivalents issued as a consequence of any such changes in the corporate structure or shares of the Company shall be subject to the same restrictions and provisions applicable to the Restricted Share Equivalents with respect to which they are issued.

4.02        Termination or Amendment of the Plan.  The Board may at any time terminate the Plan and may from time to time alter or amend the Plan or any part hereof (including any amendment deemed necessary to ensure that the Company may comply with any regulatory requirement) without shareholder approval, unless otherwise required by law or by the rules of the Securities and Exchange Commission or New York Stock Exchange.  No termination or amendment of the Plan may, without the consent of an Eligible Director, impair the rights of such director with respect to outstanding Restricted Share Equivalents.

4.03        Administration.  The Plan is to be administered by the Committee.  The Committee shall have full power and authority to adopt, amend and rescind administrative guidelines, rules and regulations relating to this Plan, to interpret the Plan and to rule on any questions relating to any of its provisions, terms and conditions.

4.04        No Obligation to Nominate.  Nothing in the Plan shall be deemed to create any obligation on the part of the Board to nominate any director for reelection by the Company’s shareholders.

4.05        Taxes and Withholding.  The Company shall have the right to withhold any taxes as required by law with respect to the cash value of the Restricted Share Equivalents.

4.06        Code Section 409A.  It is intended that the Plan comply with the requirements of Code Section 409A, and the Plan shall be so administered and interpreted.

5

4.07        Effective Dates.  The Former Plan became effective as of September 30, 1989.  The effective date of this amended and restated Plan is January 1, 2008.

4.08        References.  All statutory and regulatory references in this Plan shall include successor provisions.

4.09        Controlling Law.  This Plan shall be construed and enforced according to the laws of the Commonwealth of Pennsylvania, without regard to Pennsylvania conflict of laws rules, to the extent not preempted by federal law, which shall otherwise control.
