Form of Non-statutory Stock Option Agreement (Employees)

THIS AGREEMENT is entered into by and between CENTENE CORPORATION, a Delaware corporation (hereinafter the “Company”), and the undersigned employee of the Company (hereinafter the “Participant”).

WHEREAS, the Participant renders important services to the Company and acquires access to Confidential Information (as defined below) of the Company in connection with Participant’s relationship with the Company; and

WHEREAS, the Company desires to align the long-term interests of its valued employees with those of the Company by providing the ownership interest granted herein and to prevent former employees whose interest may become adverse to the Company from maintaining an ownership interest in the Company;

NOW, THEREFORE, in consideration of the foregoing and the mutual agreements herein contained, the parties hereto hereby agree as follows:

1. Grant of Option

This agreement evidences the grant by the Company on [GRANT DATE] (the “Grant Date”) to [PARTICIPANT NAME] (the “Participant”), of an option to purchase, in whole or in part, on the terms provided herein and in the Company’s 2012 Stock Incentive Plan (the “Plan”), a total of [NUMBER OF AWARD GRANTED] shares (the “Shares”) of common stock, $0.001 par value per share, of the Company (“Common Stock”) at [PRICE] per Share Unless earlier terminated, this option shall expire at 3:00 p.m., Central time, on [FINAL EXERCISE DATE] (the “Final Exercise Date”). If the Final Exercise Date is not an open trading date then this option shall expire at 3:00 p.m., Central Standard Time, on the last open trading date prior to the Final Exercise Date.

It is intended that the option evidenced by this agreement shall not be an incentive stock option as defined in Section 422 of the Internal Revenue Code of 1986, as amended, and any regulations promulgated thereunder (the “Code”). Except as otherwise indicated by the context, the term “Participant,” as used in this option, shall be deemed to include any person who acquires the right to exercise this option validly under its terms.

2. Vesting Schedule

This option will become exercisable (“vest”) as to one-third of the original number of Shares on the first anniversary of the Grant Date and as to an additional one-third of the original number of Shares at the end of each successive annual period following the first anniversary of

the Grant Date until the third anniversary of the Grant Date (each such vesting date, a “Vesting Date”).

The right of exercise shall be cumulative so that to the extent the option is not exercised in any period to the maximum extent permissible it shall continue to be exercisable, in whole or in part, with respect to all Shares for which it is vested until the earlier of the Final Exercise Date or the termination of this option under Section 3 hereof or the Plan.

The foregoing vesting schedule notwithstanding, if a Change in Control (as defined below) occurs and the Participant’s employment with the Company (and any parent or subsidiary thereof) is terminated by the Company (or a parent or subsidiary thereof) without Cause (as defined below) or by the Participant for Good Reason (as defined below), and the Participant’s date of termination occurs (or in the case of the Participant’s termination of employment for Good Reason, the event giving rise to Good Reason occurs) within 24 months following the Change in Control, all unvested shares shall automatically become 100% vested and shall be paid on the Participant’s date of termination (“CIC Termination Payment”). A “Change in Control” shall be deemed to have occurred if any of the events set forth in any one of the following clauses shall occur: (i) any Person (as defined in section 3(a)(9) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and as such term is modified in sections 13(d) and 14(d) of the Exchange Act), excluding a group of persons including the Participant, is or becomes the “beneficial owner” (as defined in Rule 13(d)(3) under the Exchange Act), directly or indirectly, of securities representing forty percent or more of the combined voting power of the Company’s then outstanding securities; (ii) individuals who, as of the Grant Date, constitute the Board of Directors of the Company (the “Incumbent Board”), cease for any reason to constitute a majority thereof (provided, however, that an individual becoming a director subsequent to the Grant Date whose election, or nomination for election by the Company’s stockholders, was approved by at least a majority of the directors then comprising the Incumbent Board shall be included within the definition of Incumbent Board, but excluding, for this purpose, any such individual whose initial assumption of office occurs as a result of either an actual election contest (or such terms used in Rule 14a-11 of Regulation 14A promulgated under the Exchange Act) or other actual or threatened solicitation of proxies or consents by or on behalf of a person other than the Board of Directors of the Company); or (iii) the stockholders of the Company consummate a merger or consolidation of the Company with any other corporation, other than a merger or consolidation which would result in the voting securities of the Company outstanding immediately prior thereto continuing to represent (either by remaining outstanding or by being converted into voting securities of the surviving entity) at least fifty percent of the combined voting power of the voting securities of the Company or such surviving entity outstanding immediately after such merger or consolidation. “Cause” shall include acts or omissions that the Company determines, after affording the Participant an opportunity to be heard, (i) are criminal, dishonest, fraudulent, constitute misconduct, or reflect negatively on the reputation of the Company (including any parent, subsidiary, affiliate or division of the Company); (ii) could expose the Company or any parent, subsidiary, affiliate or division of the Company to claims of illegal harassment or discrimination in employment; (iii) are material breaches of this Agreement or other agreement with the Company; or (iv) reflect continued and repeated failure to perform substantially the duties of his/her employment. “Good Reason” means: (a) if the Participant is a party to an employment or service agreement with the Company or its affiliates and such agreement provides for a definition of Good Reason, the

definition contained therein; or (b) if no such agreement exists or if such agreement does not define Good Reason, the occurrence of one or more of the following without the Participant's express written consent, which circumstances are not remedied by the Company within thirty (30) days of its receipt of a written notice from the Participant describing the applicable circumstances (which notice must be provided by the Participant within ninety (90) days of the Participant's knowledge of the applicable circumstances): (i) any material, adverse change in the Participant's responsibilities, authority, title, status or reporting structure; (ii) a material reduction in the Participant's base salary or short-term cash incentive opportunity; or (iii) a geographical relocation of the Participant's principal office location by more than fifty (50) miles; provided that, the Participant in fact terminates employment for Good Reason within one hundred fifty (150) days following the initial existence of the circumstances giving rise to such Good Reason.

3. Exercise of Option

Each election to exercise this option shall be in writing, signed by the Participant, and received by the Company at its principal office, accompanied by this agreement, and payment in full in the manner provided in the Plan. Common Stock purchased upon the exercise of this option shall be paid for as follows

The Participant may purchase less than the number of shares covered hereby, provided that no partial exercise of this option may be for any fractional share or for fewer than ten whole shares.

(b) Continuous Relationship with the Company Required. Except as otherwise provided in this Section 3, this option may not be exercised unless the Participant, at the time he or she exercises this option, is, and has been at all times since the Grant Date, an employee, officer or director of, or consultant or advisor to, the Company or any other entity the employees, officers,

Notwithstanding the foregoing, if the Participant, prior to the Final Exercise Date, violates the non-competition or confidentiality provisions of any employment, consulting, advisory, nondisclosure, non-competition or other agreement between the Participant and the Company, the right to exercise this option shall terminate immediately upon such violation.

(d) Exercise Period Upon Death or Disability. If the Participant dies or becomes disabled (within the meaning of Section 22(e)(3) of the Code) prior to the Final Exercise Date while he or she is an Eligible Participant and the Company has not terminated such relationship for “cause” as specified in paragraph (e) below, this option shall be exercisable, within the period of 90 days following the date of death or disability of the Participant, by the Participant (or in the case of death by an authorized transferee), provided that this option shall be exercisable only to the extent that this option was exercisable by the Participant on the date of his or her death or disability, and further provided that this option shall not be exercisable after the Final Exercise Date.

(e) Discharge for Cause. If the Participant, prior to the Final Exercise Date, is discharged by the Company for “cause” (as defined below), the right to exercise this option shall terminate immediately upon the effective date of such discharge. “Cause” shall include acts or omissions that the Company determines, after affording the Participant an opportunity to be heard, (i) are criminal, dishonest, fraudulent, constitute misconduct, or reflect negatively on the reputation of the Company (including any parent, subsidiary, affiliate or division of the Company); (ii) could expose the Company or any parent, subsidiary, affiliate or division of the Company to claims of illegal harassment or discrimination in employment; (iii) are material breaches of this Agreement or other agreement with the Company; or (iv) reflect continued and repeated failure to perform substantially the duties of his/her employment.

(f) Right to Exercise. The Participant’s right to exercise this option and to retain any gains upon a sale or other disposition of the Shares therefrom is subject to the Participant’s compliance with the covenants set forth in Section 4 hereof.

4. Optionee’s Covenants. For and in consideration of the option hereunder, the Participant agrees to the provisions of this Section 4.

(a) Confidential Information. As used in this Section 4, “Confidential Information” shall mean the Company’s trade secrets and other non-public proprietary information relating to the Company or the business of the Company, including information relating to financial statements, existing or proposed target markets, employee skills and compensation, employee data, acquisition targets, servicing methods, programs, strategies and information, analyses, expansion plans and strategies, profit margins, financial, promotional, training or operational information,

and other information developed or used by the Company that is not known generally to the public or the industry. Confidential Information shall not include any information that is in the public domain or becomes known in the public domain through no wrongful act on the part of the Participant.

(b) Non-Disclosure. The Participant agrees that the Confidential Information is a valuable, special and unique asset of the Company’s business, that such Confidential Information is important to the Company and the effective operation of the Company’s business, and that during employment with the Company and at all times thereafter, the Participant shall not, directly or indirectly, disclose to any competitor or other person or entity (other than current employees of the Company) any Confidential Information that the Participant obtains while performing services for the Company, except as may be required in the Participant’s reasonable judgment to fulfill the Participant’s duties hereunder or to comply with any applicable legal obligation.

(c) Non-Competition; Non-Solicitation.

(d) Enforcement. If any of the provisions of this Section 4 shall be held to be invalid or unenforceable by a court of competent jurisdiction, the remaining provisions or subparts thereof shall nevertheless continue to be valid and enforceable according to their terms. Further, if any restriction contained in the provisions or subparts of this Section 4 is held to be overbroad or unreasonable as written, the parties agree that the applicable provision should be considered to be amended to reflect the maximum period, scope or geographical area deemed reasonable and enforceable by the court and enforced as amended.

(e) Remedy for Breach.

(1) Because the Participant’s services are unique and because the Participant has access to the Company’s Confidential Information, the parties agree that any breach or threatened breach of this Section 4 will cause irreparable harm to the Company and that money damages alone would be an inadequate remedy. The parties therefore agree that, in the event of any breach or threatened breach of this Section 4, and in addition to all other rights and remedies available to it, the Company may apply to any court of competent jurisdiction for specific performance and/or injunctive or other relief, without a bond, in order to enforce or prevent any violations of the provisions of this Section 4.

(2) The Participant shall immediately repay to the Company a cash sum in the principal amount equal to all gross proceeds (before-tax) realized by the Participant upon the sale or other disposition of shares occurring at any time during the period commencing on the date that is three years before the date of the termination of the Participant’s employment with the Company and ending on the date of the breach or threatened breach of this Section 4 (the “Refund Period”), together with interest accrued thereon from the date of such breach or threatened breach, at the prime rate (compounded calendar monthly) as published from time to time in The Wall Street Journal, electronic edition (“Interest”); and

(3) The Participant shall repay to the Company a cash sum equal to the fair market value of all Shares and all or any portion of the option transferred by the Participant as a gift or gifts at any time during the Refund Period, together with Interest, and for which purpose, “fair

market value” per Share shall be the Fair Market Value of one Share on the date such gift occurs and per option Share shall be the positive difference, if any, between the Fair Market Value of a Share and the exercise price of such option.

(4) The Participant acknowledges and agrees that nothing contained herein shall be construed to be an excessive remedy to prohibit the Company from pursuing any other remedies available to it for such actual or threatened breach, including but not limited to the recovery of money damages, proximately caused by the Participant’s breach of this Section 4.

(f) Survival. The provisions of this Section 4 shall survive and continue in full force in accordance with their terms notwithstanding any forfeiture, termination or expiration of this option in accordance with its terms or any termination of the Participant’s employment for any reason (whether voluntary or involuntary).

5. Withholding

No Shares will be issued pursuant to the exercise of this option unless and until the Participant pays to the Company, or makes provision satisfactory to the Company for payment of, any federal, state or local withholding taxes required by law to be withheld in respect of this option.

6. Nontransferability of Option

This option may not be sold, assigned, transferred, pledged or otherwise encumbered by the Participant, either voluntarily or by operation of law, except by will or the laws of descent and distribution, and, during the lifetime of the Participant, this option shall be exercisable only by the Participant.

7. Provisions of the Plan

This option is subject to the provisions of the Plan, a copy of which is furnished to the Participant with this option.

In Witness Whereof, the Company has caused this option to be executed under its corporate seal by its duly authorized officer. This option shall take effect as a sealed instrument.
