Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) Shares have been transferred with the stipulation that, at a minimum, they are held until financial results for the quarter ending June 30, 2013 are reported. Mr. Neidorff does not have any continuing investment control over these shares.
(2) Ownership includes previous awards of 410,000 restricted stock units subject to vesting requirements. Since the date of Mr. Neidorff's last ownership report, 75,000 performance stock units were forfeited due to the Company not meeting performance conditions.
(3) Each share of phantom stock represents the right to receive the fair market value of one share of Centene common stock.
(4) The phantom stock has no formal expiration date. The phantom stock will be settled in cash or other non-Company securities upon Mr. Neidorff's termination with the Company or on such other date Mr. Neidorff may elect.
