This Amendment (this “Amendment”) to the Anthem, Inc. Executive Agreement Plan (the “Plan”) is made by Anthem, Inc. (“Anthem”).

WHEREAS, Anthem and its subsidiaries and affiliates (collectively, the “Company”) maintains the Plan, originally effective January 1, 2006, and last restated effective December 2, 2014; and

WHEREAS, the Company desires to amend the Plan, effective as of the date this Amendment is executed as set forth on the signature page of this Amendment (the “Effective Date”), to provide for certain key executive employees upon their termination under certain circumstances.

NOW, THEREFORE, pursuant to rights reserved under Section 7.3 of the Plan, Anthem hereby amends the Plan as of the Effective Date, as set forth below.

1.    Defined Terms. All capitalized terms, not otherwise defined herein, have the meaning given to such terms in the Plan.

2.    Section 3.2(a). Section 3.2(a) of the Plan is hereby amended by adding the below provisions immediately prior to Section 3.2(b).

Notwithstanding anything to the contrary set forth above in this Section 3.2(a), in the event:

(1)    a Participant has an Eligible Separation from Service at any time during the period commencing on the date that certain Agreement and Plan of Merger among Anthem, Anthem Merger Sub Corp., and Cigna Corporation dated as of July 23, 2015 (the “Merger Agreement”) is approved under the Hart-Scott-Rodino Antitrust Improvements Act of 1976 in accordance with Section 3.1(c)(iii)(A) (the “HSR Approval Date”) and ending on the third anniversary of the “Closing Date” as defined in the Merger Agreement (“Cigna Integration Period”), and

(2)    such Participant participated in the Plan as of the HSR Approval Date,

then for purposes of determining the percentages and periods to be used in the calculations set forth above in Sections 3.2(a), 3.2(a)(i), 3.2(a)(ii) and 3.2(a)(iv), the percentages and periods set forth in columns (A) and (B) in the below table (“Table II”) will be used during the Cigna Integration Period, and the percentages and periods set forth in columns (A) and (B) in the above table (“Table I”) will not be used during the Cigna Integration Period.

For the purpose of applying Table II, a Participant’s position is his or her position as of the HSR Approval Date, regardless of
