2018 NOTICE OF MEETING AND PROXY STATEMENT
PROPOSAL ONE: ELECTION OF DIRECTORS


Corporate Governance and Risk Management

We believe that good corporate governance is important to ensure that we are managed for the long-term benefit of our stockholders. We also recognize the connection between good corporate governance and our ability to create and sustain value for our stockholders. Our Ethics and Compliance Program provides methods by which we further enhance operations, safeguard against fraud and abuse and help assure that our values are reflected in everything we do. We have also reviewed and believe we are in compliance with the provisions of the Sarbanes-Oxley Act of 2002, the rules of the SEC, and the listing standards of the NYSE. Our Board of Directors has adopted Corporate Governance Guidelines addressing, among other things, director qualifications and responsibilities, duties of key Board Committees, director compensation and management succession. A current copy of the Corporate Governance Guidelines is posted on our website, www.centene.com.

Our Board of Directors has adopted a Business Ethics and Conduct Policy (the Policy) which is applicable to all directors, officers and employees of the Company, including the Principal Executive Officer, Principal Financial Officer and Principal Accounting Officer. While no policy can replace the thoughtful behavior of an ethical director, officer or employee, we believe the Policy will, among other things, focus our Board and management on areas of ethical risk, provide guidance for recognizing and responding to ethical issues, provide mechanisms to report unethical conduct and generally help foster a culture of honesty and accountability. Any amendment to, or waiver of, the Policy involving a director or executive officer may only be made by the Board or a committee of the Board. A current copy of the Policy is posted on our website, www.centene.com. Any future amendments of the Policy will be promptly disclosed on our website.
Our policy concerning pre-approval of related party transactions is incorporated into the provisions of the Policy regarding conflicts of interest. As part of the Policy, our directors, officers and employees are responsible for disclosing any transaction or relationship that reasonably could be expected to give rise to a conflict of interest to the Chief Compliance Officer of the Company or the Board of Directors, in the case of an executive officer or director, who shall be responsible for determining whether such transaction or relationship constitutes a conflict of interest.

The Board of Directors oversees execution of the Company’s enterprise risk management (ERM) framework with assistance provided by Board Committees. This oversight is enabled by quarterly risk reporting from executive management. These reports are designed to provide visibility into the identification, assessment, monitoring and management of critical risks, including strategic, operational, financial, compensation, regulatory, compliance, investment, information security and other risks. In addition, the Board and its committees are informed of emerging risks and opportunities which could impact the Company’s risk profile. This information is combined with other data to evaluate the Company’s performance in relation to tolerance levels established in Centene’s risk appetite framework on a quarterly basis. Management is responsible for executing day-to-day risk activities, and ensuring that ERM is integrated with our strategic decision-making and financial budgeting processes.
As noted above, the Board uses its Committees to assist in its risk oversight function:

Our Audit Committee assists in the oversight of our financial and reporting risks, disclosure risk and procedures, business ethics and conduct risks, investment, and risk assessment and management policies. The Company's Executive Vice President of Internal Audit & Risk Management, who reports to the Audit Committee and Chief Executive Officer, assists the Company in identifying and evaluating risk management controls and methodologies to address risks and provides reports to the Audit Committee quarterly. The Audit Committee meets privately with representatives from the Company's independent registered public accounting firm and the Company's Executive Vice President of Internal Audit & Risk Management.

Our Compensation Committee assists in the oversight of risks associated with our compensation plans and policies. Please see the discussion in the “Compensation Discussion & Analysis,” or “CD&A,” under the heading “Risk Disclosure” for a discussion of elements intended to mitigate excessive risk taking by our employees.

Our Nominating and Governance Committee assists in the oversight of Board processes and corporate governance-related risk.

Our Technology Committee assists in the oversight of risks associated with our systems and technology, including risks related to cybersecurity.

Our Board of Directors and its Committees are supported by our Management Oversight Committee, which formally oversees our enterprise and security risk management (ERM and SRM, respectively) functions. The Management Oversight Committee is a cross-functional governance group comprised of certain members of our executive leadership team. The duties of the Management Oversight Committee include:

Oversight of the process used to identify, assess, respond, and report on risk and compliance issues;

Determine Centene’s risk appetite and risk tolerance levels. All changes are reviewed and approved by the Board;

Review of performance measures against established risk tolerances and recommend corrective action where appropriate;

Review of findings from internal audit activities for accuracy and clarify;

Provide direction for resource allocation to address internal audit findings and/or gaps identified through ERM, SRM, and Corporate Compliance activities; and

Validate assignment of risk owners associated with identified exposures and monitor plans to address documented findings/gaps.
Continued Commitment to Diversity and Inclusion

Our corporate purpose is to transform the health of our communities, one person at a time. Consistent with this purpose, diversity and inclusion are among our highest priorities. Our Board of Directors believes that supporting an inclusive and respectful work environment through training, education and community engagement activities is important to attract and retain a talented workforce. We encourage our Board members, senior executives, and employees to become actively involved with organizations making a positive impact on communities. Our efforts include the intentional placement of service centers and other facilities in economically disadvantaged locations such as Ferguson, Missouri and Tyler, Texas as well as a commitment to supplier diversity.

Our Corporate Governance Guidelines make clear that we are committed to a policy of inclusiveness which includes actively identifying and recruiting diverse candidates, including women, veterans, people with disabilities, and minorities, as part of the process for selecting new Board members. In February 2018, we added Jessica L. Blume to our Board. Ms. Blume's mix of skills and experience, especially her background in finance and technology, will be both valuable and relevant to our Board.

Consistent with our local approach model, we often recruit individuals from local communities to serve as directors on the governing boards of our regulated health plan subsidiaries. Of 98 individuals serving in this capacity at the start of 2018, roughly one-third of the directors were women and nearly 40% were African American, Hispanic, Asian or Native American.

The Board's Role in Succession Planning

As reflected in our Corporate Governance Guidelines, the Board's primary responsibilities include planning for Chief Executive Officer (CEO) succession and monitoring and advising on succession planning for other executive officers. The Board's goal is to have a long-term and continuing program for effective senior leadership development and succession. The Board also has contingency plans in place for emergencies such as departure, death, or disability of the CEO or other executive officers.
Compensation Committee Interlocks and Insider Participation

Robert K. Ditmore (Chair), Orlando Ayala, David L. Steward, Tommy G. Thompson and Richard A. Gephardt were members of the Compensation Committee during 2017. During 2017, none of our executive officers served as a director or member of the Compensation Committee, or other committee serving an equivalent function, of any other entity that has one or more of its executive officers serving as a member of our Board of Directors or Compensation Committee. During 2017, no member of the Compensation Committee had a relationship that must be described under the SEC rules relating to disclosure of related person transactions. None of the current members of our Compensation Committee has ever been an officer or employee of Centene or any of our subsidiaries.
Related Party Transactions

None.
Director Independence

Our Board of Directors has affirmatively determined that all directors except Michael F. Neidorff, our Chairman and Chief Executive Officer, as well as all of the members of each of the Board's committees, are independent as defined under the rules of the NYSE, including, in the case of all members of the Audit Committee, the independence requirements contemplated by Rule 10A-3 under the Exchange Act and in the case of all members of the Compensation Committee, the enhanced independence requirements under the rules of the NYSE. In the course of the Board's determination regarding the independence of each non-employee director, it considered any transactions, relationships and arrangements as required by the rules of the NYSE. In particular, with respect to each of the most recent three completed fiscal years, the Board evaluated Mr. Roberts' position on the Board of the Missouri History Museum. The Board determined that contributions made by the Company from 2015 - 2017 to the Missouri History Museum are less than 2% of the Museum’s consolidated gross revenues during the respective years.

All directors, excluding Michael F. Neidorff, have no direct or indirect material relationship with us except for their role as a director or stockholder. The Board also broadly considers what it deems to be all relevant facts and circumstances in determining the independence of its members.

The Technology Committee’s primary responsibility is to assist the Board in reviewing the Company’s information technology ("IT") programs, strategy, plans and development. The Technology Committee’s responsibilities include, among others:

reviewing the status of the existing IT programs;
reviewing significant technology opportunities and monitoring the progress of special initiatives;
making recommendations to the Board with respect to IT related projects and investments that require Board approval; and
assisting in the oversight of risks associated with our systems and technology, including risks related to cybersecurity.
The Government and Regulatory Affairs Committee’s primary responsibility is to assist the Board in identifying, evaluating and monitoring legislative, political and regulatory trends and addressing public policy issues and concerns that affect or could affect the Company. The Government and Regulatory Affairs Committee’s responsibilities include, among others:

making recommendations to the Board regarding the amendment and/or adoption of new policies, procedures and/or practices by the Company;
reviewing and reporting on the Company’s position on key public policy issues under consideration in federal and state legislative, regulatory and judicial forums; and
overseeing the management by the Company of risks as they relate to the Company’s compliance with regulatory requirements and rapidly changing healthcare, insurance and other legislation.

Board of Directors

Our Board of Directors has responsibility for establishing broad corporate policies and reviewing our overall performance rather than day-to-day operations. The Board's primary responsibility is to oversee the management of the Company and, in doing so, serve the best interests of the Company and its stockholders. The Board selects, evaluates and provides for the succession of executive officers and, subject to stockholder election, directors. It reviews and approves corporate objectives and strategies, and evaluates significant policies and proposed major commitments of corporate resources. Management keeps the directors informed of its activities through regular written reports and presentations at Board and committee meetings.
The Board currently combines the role of Chairman of the Board with the role of Chief Executive Officer, coupled with a Presiding Director position to further strengthen the governance structure. The Board believes this provides an efficient and effective leadership model for the Company. Combining the Chairman and CEO roles fosters clear accountability, effective decision-making, and alignment on corporate strategy. The Board periodically reviews its leadership structure. To assure effective independent oversight, the Board has adopted a number of governance practices, including:

a strong, independent, clearly-defined Presiding Director role;
executive sessions of the independent directors in connection with every Board meeting; and
annual performance evaluations of the Chairman and CEO by the independent directors.

Our Board of Directors has appointed Robert K. Ditmore “Presiding Director” to preside at all executive sessions of “non-management” directors, as defined under the rules of the NYSE. The Presiding Director's role includes leading the Board's processes for selecting and evaluating the Chief Executive Officer and presiding at all meetings of the Board at which the Chairman is not present, including executive sessions of the independent directors.

2018 NOTICE OF MEETING AND PROXY STATEMENT
PROPOSAL ONE: ELECTION OF DIRECTORS

Our Corporate Governance Guidelines require the Board to conduct an annual self-evaluation to determine whether it and its committees are functioning effectively. The Nominating and Governance Committee receives comments from all directors and reports annually to the Board with an assessment of the Board’s performance. This is discussed with the full Board following the end of each fiscal year. The assessment focuses on the Board’s contribution to the Company and specifically focuses on areas in which the Board or management believes that the Board could improve.

Audit Committee

The Audit Committee's responsibilities include:
appointing, retaining, evaluating, terminating, approving the compensation of, and assessing the independence of our independent registered public accounting firm;
overseeing the work of our independent registered public accounting firm, including through the receipt and consideration of certain reports from the independent registered public accounting firm;
reviewing and discussing with management and the independent registered public accounting firm our annual and quarterly financial statements and related disclosures;
monitoring our internal control over financial reporting, disclosure controls and procedures and code of business conduct and ethics;
overseeing our internal audit function;
discussing our risk management policies;
establishing policies regarding hiring employees from our independent registered public accounting firm and procedures for the receipt and retention of accounting-related complaints and concerns;
meeting independently with our internal auditing staff, independent registered public accounting firm and management; and
preparing the Audit Committee report required by SEC rules.
The Board has determined that John R. Roberts, Jessica L. Blume and Frederick H. Eppinger are “audit committee financial experts” as defined in Item 407(d)(5) of Regulation S-K and that each member of the Audit Committee is "financially literate" under the applicable NYSE rules.

Compensation Committee

The Compensation Committee oversees our activities in the area of compensation and benefits (generally with regard to all employees and specifically with regard to our Named Executive Officers, or NEOs, identified in the Summary Compensation Table, as well as other officers) and reviews and makes recommendations concerning compensation-related matters to be submitted to the Board and/or stockholders for approval. The Board has determined that each of the members of the Compensation Committee is “independent,” as defined under the rules of the NYSE. The Compensation Committee's responsibilities include:

evaluating compensation policies and practices to determine if they may be influencing employees to take excessive risks;
annually reviewing and approving corporate goals and objectives relevant to our Chief Executive Officer's compensation;
reviewing and making recommendations to the Board with respect to our Chief Executive Officer's compensation;
reviewing and approving, or making recommendations to the Board, with respect to the compensation of our other executive officers;

overseeing an evaluation of our senior executives;
overseeing and administering our equity incentive plans; and
reviewing and making recommendations to the Board with respect to director compensation. 

Members of management assist the Compensation Committee in its responsibilities by providing recommendations for the Compensation Committee's approval concerning the design of our compensation program for our executive officers other than our Chief Executive Officer, including our NEOs, as well as recommended award levels. The design of our compensation program for our Chief Executive Officer is recommended by the Compensation Committee and approved by the Board without any approval of the Chairman, who is the Company's Chief Executive Officer.

The Compensation Committee considered information and data regarding executive compensation supplied by management and by Exequity, LLP, compensation consultants that were engaged directly by the Compensation Committee to provide advice with respect to base salaries, bonus targets and long-term incentives.

In 2017, the Company utilized Exequity, LLP to provide advice with respect to the base salaries, bonus targets and long-term incentives of our officers, including our NEOs. The consultants analyzed the compensation levels of the NEOs of the industry peer group developed by Exequity, LLP for the most recently completed fiscal year. As discussed under the CD&A, the Compensation Committee considered this information, along with a variety of other factors, in reviewing our executive compensation in 2017.
The Compensation Committee has reviewed the independence of Exequity, LLP in light of SEC rules and NYSE listing standards, including the following factors: (1) other services provided to us by the consulting firm; (2) fees paid by us as a percentage of consulting firm's total revenue; (3) policies or procedures maintained by the consulting firm that are designed to prevent a conflict of interest; (4) any business or personal relationships between the compensation consultant and a member of the Compensation Committee; (5) any company stock owned by the compensation consultant; and (6) any business or personal relationships between our executive officers and the senior advisor. The Compensation Committee discussed these considerations and concluded that the compensation consultants' work for the committee does not raise any conflict of interest.

The Compensation Committee delegates to management the authority to grant certain stock options and restricted stock units under the 2012 Stock Incentive Plan. Our Chief Executive Officer is authorized to issue awards (other than to himself) of up to 60,000 shares to any newly hired executive and up to 24,000 shares to any one person during a calendar year, and is required to report any such grants to the Compensation Committee at the following Compensation Committee meeting. The delegation of authority may be terminated by the Compensation Committee at any time and for any reason. All internal promotions and equity grants to a corporate officer and all offers to any “Executive Officer” (as defined by Rule 3b-7 under the Exchange Act) require Compensation Committee approval.

Nominating and Governance Committee

The Nominating and Governance Committee's responsibilities include:
identifying individuals qualified to become members of the Board;
recommending to the Board the persons to be nominated for election as directors and to each of the Board's committees;
reviewing and making recommendations to the Board with respect to management succession planning;
reviewing and recommending to the Board corporate governance principles; and
overseeing an annual evaluation of the Board's performance.

Director Candidates

The process followed by the Nominating and Governance Committee to identify and evaluate Director candidates includes requests to Board members and others for recommendations, meetings from time to time to evaluate biographical information and background material relating to potential candidates and interviews of selected candidates by members of the Nominating and Governance Committee and the Board.
In considering whether to recommend any particular candidate for inclusion in the Board's slate of recommended director nominees, the Nominating and Governance Committee will apply the criteria set forth in our Corporate Governance Guidelines. These criteria include the candidate's integrity, business acumen, knowledge of our business and industry, age, experience, diligence, conflicts of interest and the ability to act in the interests of all stockholders. The Nominating and Governance Committee does not assign specific weights to particular criteria and no particular criterion is a prerequisite for each prospective nominee. We believe that the backgrounds and qualifications of our directors, considered as a group, should provide a composite mix of experience, knowledge and abilities that will allow the Board to fulfill its responsibilities.

We believe that it is important that our directors represent and understand the diverse populations that we serve. Indeed, Board membership should reflect diversity in its broadest sense, including persons diverse in background, geography, perspective, gender, and ethnicity. The Board is particularly interested in maintaining a mix that includes the following backgrounds:

Public company governance
Healthcare
Service and insurance industry
Companies with revenues greater than $1 billion
Public accounting
Community involvement
Investment banking
International
Financial services
Technology
Organizational development
Political and regulatory relationships
Experience as a Chief Executive Officer

Stockholders may recommend individuals to the Nominating and Governance Committee for consideration as potential director candidates by submitting their names, together with appropriate biographical information and background materials to Nominating and Governance Committee, c/o Corporate Secretary, Centene Corporation, 7700 Forsyth Boulevard, St. Louis, Missouri 63105. Assuming that appropriate biographical and background material has been provided on a timely basis in accordance with the procedures set forth in our By-Laws, the Nominating and Governance Committee will evaluate stockholder-recommended candidates by following substantially the same process and applying substantially the same criteria as it follows for candidates submitted by others.

Proxy Access

Responding to the insights and feedback of our stockholders is pivotal to maintaining our strong corporate governance. Based on feedback we received from our stockholders, we proactively adopted an amendment to the Company's By-Laws in February 2018 to implement proxy access. Proxy access allows stockholders who meet minimum stock ownership and holding period requirements and who comply with specified procedural and disclosure requirements the opportunity to include their director nominees in the Company’s proxy materials. We believe proxy access gives our long-term stockholders a valuable right and enables them to have an important voice in director elections. The following is a summary outlining key details of requirements related to our proxy access By-Law:
Ownership Thresholdat least 3% of the Company's outstanding common stock
Group Ownershipa group of 20 or less holders
Ownership Periodat least 3½ years of continuous ownership
Number of Nomineesthe greater of two individuals or 20% of the Board (not to exceed one-half of the number of directors up for election at the annual meeting)
Director Tenure and Commitment to Refreshment

We are proud of our Board of Directors, which for years has maintained excellent chemistry and internal working dynamics while having members with differing political affiliations and diverse backgrounds. We believe that the existing members of our Board continue to provide valuable insights and have contributed significantly to the success of our Company. The Board recognizes, however, the importance of planning for the succession of Board leadership and of bringing on new members. In the current year, we followed through on this commitment through our nomination of Jessica L. Blume to our Board. Ms. Blume has strong leadership skills and deep financial background with over 25 years of experience in professional services.
Communicating with Independent Directors

The Board will give appropriate attention to written communications that are submitted by stockholders and other interested parties and will respond as appropriate. The Chairman of the Nominating and Governance Committee, with the assistance of our Chief Executive Officer, is primarily responsible for monitoring communications from stockholders and other interested parties and for providing copies or summaries to the other directors as he or she considers appropriate. Under procedures approved by a majority of the independent directors, communications are forwarded to all directors if they relate to important substantive matters and include suggestions or comments considered to be important for the directors to know.

Stockholders and interested parties who wish to send communications on any topic to the Board should address such communications to Board of Directors c/o Corporate Secretary, Centene Corporation, 7700 Forsyth Boulevard, St. Louis, Missouri 63105. Any stockholder or interested party who wishes to communicate directly with our Presiding Director, or with our non-employee directors as a group, should also follow the foregoing method.

Assumptions used in the calculation of this amount for the fiscal year ended December 31, 2017, are included in footnote 15 to the Company's audited financial statements for the fiscal year ended December 31, 2017, included in the Company's Annual Report on Form 10-K filed with the SEC on February 20, 2018. There can be no assurance that the grant date fair value of Stock Awards will ever be realized.
2All other compensation for Mr. Eppinger, Mr. Gephardt, Mr. Roberts and Mr. Thompson reflects charitable contributions of $25,000 and for Mr. Ditmore reflects charitable contributions of $5,000 made or pledged during 2017 under the Company's Board of Directors Charitable Matching Gift Program. Mr. Gephardt's compensation also reflects personal use of Company provided aircraft valued on a cost-per-flight-hour charge developed by a nationally recognized and independent service which reflects the operating and periodic maintenance costs of the aircraft, crew travel expenses and other miscellaneous costs. All Other Compensation for each director also includes group excess liability insurance policy premiums paid by the Company.

Non-employee directors currently receive a quarterly retainer fee of $31,250, provided that the director elects 100% payment pursuant to the Company's Non-Employee Directors Deferred Stock Compensation Plan to be paid in company stock upon retirement or termination from the Board. Directors not making this election receive a quarterly retainer fee of $25,000. In addition, the Chairman of the Audit Committee receives a quarterly fee of $7,500, the Chairman of the Compensation Committee receives a quarterly fee of $5,000, and the Chairman of the Nominating and Governance Committee, Government and Regulatory Affairs Committee, and Technology Committee each receives a quarterly fee of $3,750. The Company also pays a quarterly fee of $6,250 to the Presiding Director of the Board. All fixed cash fees are eligible for deferral under the Non-Employee Directors Deferred Stock Compensation Plan. Expense recognized in conjunction with the deferred stock election is included in the “Stock Awards” column in the Director Compensation Table above.

The Board receives additional variable cash compensation dependent on the number of meetings held annually. Once the number of full Board of Director meetings held exceeds six, non-employee directors receive $2,000 per meeting, not to exceed $20,000 annually. The variable cash compensation was effective for the 2017 year and is included within Fees Earned or Paid in Cash in the table above.

As part of non-employee director compensation and to recognize each member's stock holding requirement of 40,000 shares, each director receives an annual stock grant valued at $200,000 based on first quarter average stock price prior to the grant. Each new non-employee director is granted an option under our 2012 Stock Incentive Plan to purchase 10,000 shares of our common stock vesting in three equal annual installments commencing on the first anniversary of the grant date. In April 2017, each member of the Board received a grant of 3,000 restricted shares of our common stock (target value of $200,000). The restricted shares vest on the April 2018 Annual Meeting of Stockholders, subject to meeting Board of Director meeting attendance conditions.

2018 NOTICE OF MEETING AND PROXY STATEMENT
PROPOSAL TWO: ADVISORY RESOLUTION TO APPROVE EXECUTIVE COMPENSATION

Proposal Two: Advisory Resolution to Approve Executive Compensation

At our 2017 Annual Meeting of Stockholders, our stockholders approved the Company's executive compensation. Pursuant to Section 14A of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), we are again holding an advisory vote on the Company's executive compensation, as described in this Proxy Statement (commonly referred to as "say-on-pay"). In accordance with the results of the vote we conducted at the 2017 Annual Meeting on the frequency of say-on-pay votes, we present a say-on-pay vote every year.

We encourage stockholders to review the Compensation Discussion and Analysis included in this Proxy Statement. Our executive compensation program has been designed to implement the Company's compensation philosophy of paying for performance by making decisions based on promoting the Company's corporate mission statement and creating long-term stockholder value. As discussed in Section 3 of CD&A, the following principles guide the Company's compensation philosophy:

Pay for Performance;
Create Long-Term Stockholder Value;
Foster a Culture of Risk Management and Compliance; and
Attract and Retain Top Executive Talent.

This philosophy is evidenced by the following:

We provide a significant part of executive compensation in the form of at-risk annual incentive and long-term incentive compensation; for example, we have withheld or reduced payments under our incentive programs when financial measures have not been fully achieved.

Our annual incentive and long-term incentive opportunities are substantially based on corporate financial measures closely correlated with achieving long-term stockholder value, such as earnings per share, revenue growth targets, pre-tax operating margins and total shareholder return. Annual and long-term incentive opportunities also reflect the impact to the current year income for new contracts awarded that drive future revenue growth and take into account the costs associated with the contract procurements which occur prior to revenue generation.

We provide a mix of short-term, long-term, cash and non-cash compensation that we believe allows us to strike a balance between offering competitive executive compensation packages, motivating our executives without fostering excessive risk-taking and linking Executive Officer compensation with the creation of long-term stockholder value.

The Board of Directors strongly endorses the Company's executive compensation program and recommends that stockholders vote in favor of the following resolution:

RESOLVED, that the stockholders approve the compensation of those NEOs listed in the Summary Compensation Table of this proxy statement, who we refer to in this proxy statement as the NEOs, as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission (SEC), including the Compensation Discussion and Analysis and the tabular and narrative disclosure included herein under “Information about Executive Compensation”.


18 Centene Corporation

2018 NOTICE OF MEETING AND PROXY STATEMENT
PROPOSAL TWO: ADVISORY RESOLUTION TO APPROVE EXECUTIVE COMPENSATION


Because the vote is advisory, it will not be binding upon the Board of Directors or the Compensation Committee and neither the Board of Directors nor the Compensation Committee will be required to take any action as a result of the outcome of the vote on this proposal. The Compensation Committee strongly considers the views of the Company's stockholders when making compensation decisions. Additionally, the Compensation Committee monitors the results of the annual advisory “say-on-pay” proposal and incorporates such results as one of many factors considered in connection with the discharge of its responsibilities. Please see the Compensation Discussion and Analysis section of this Proxy Statement for a more detailed discussion of the actions the Committee took during 2017 based on stockholder feedback.

The Board recommends a vote “FOR” the approval of the compensation of the NEOs, as disclosed in this Proxy Statement pursuant to the compensation disclosure rules of the SEC.

PROPOSAL THREE: RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM


Proposal Three: Ratification of Appointment of Independent Registered Public Accounting Firm

KPMG LLP audited our financial statements for the fiscal year ended December 31, 2017. The Board of Director's Audit Committee is directly responsible for the appointment, compensation, retention and oversight of the independent external audit firm retained to audit our financial statements. The Audit Committee has appointed KPMG LLP to serve as our independent registered public accounting firm for the current fiscal year, and we are asking stockholders to ratify this appointment. KPMG LLP has been retained as our external auditor continuously since 2005. Stockholder ratification of this selection is not required by our By-Laws or other applicable legal requirements. Our Board of Directors is, however, submitting the selection of KPMG LLP to stockholders for ratification as a matter of good corporate practice. In the event that stockholders fail to ratify the selection, the Audit Committee will consider whether or not to retain that firm. Even if the selection is ratified, the Audit Committee, in its discretion, may direct the appointment of a different independent registered public accounting firm at any time during the year if the Audit Committee believes that a change would be in the best interests of the Company and our stockholders.

We expect that representatives of KPMG LLP will be present at our Annual Meeting of Stockholders to answer appropriate questions. They will have the opportunity to make a statement if they desire to do so.

The affirmative vote of the holders of a majority of the votes cast at the meeting is being sought to ratify the selection of KPMG LLP as our independent registered public accounting firm for the current fiscal year. The Committee believes the continued retention of KPMG LLP to serve as our independent registered public accounting firm is in the best interests of the Company and our stockholders.

The Board recommends that stockholders vote “FOR” the ratification of the selection of KPMG LLP to serve as our independent registered public accounting firm for the fiscal year ending December 31, 2018.

The Audit Committee has adopted policies and procedures relating to the approval of all audit, audit-related, tax and other services that are to be performed by our independent registered public accounting firm. This policy generally provides that the Company will not engage its independent registered public accounting firm to render audit, audit-related, tax or other services unless the service is specifically approved in advance by the Audit Committee or the engagement is entered into pursuant to one of the pre-approval procedures described below.

AUDIT COMMITTEE REPORT

Audit Committee Report

The Audit Committee operates under a written charter adopted by the Company’s Board of Directors. The charter, which was last amended in February of 2009, outlines the Audit Committee’s duties and responsibilities. The Audit Committee reviews the charter annually and works with the Board of Directors to amend the charter based on the Audit Committee’s evolving responsibilities. The Audit Committee charter is available on the Company’s website at www.centene.com/investors/corporate-governance.

The Audit Committee of the Company’s Board of Directors consists of four non-employee directors who are independent under the rules of the NYSE, the rules of the SEC and the Company's Standards for Director Independence. Three of the Audit Committee members are considered Audit Committee Financial Experts as defined by the SEC and all are financially literate under the applicable NYSE rules. The Audit Committee assists the Board of Directors in its oversight of the accounting and financial reporting process of the Company. Specifically, the Audit Committee has responsibility for providing independent objective oversight of the accounting and financial reporting process of the Company, selecting and evaluating the independent registered public accounting firm, which reports directly to the Audit Committee and oversees the performance of the Company's internal audit function.

Management has the primary responsibility for the preparation of the Company's financial statements and the overall reporting process, for maintaining adequate internal control over financial reporting and, with the assistance of the Company's internal auditors, for assessing the effectiveness of the Company's internal control over financial reporting. The Company's independent registered public accounting firm is responsible for performing an independent audit of the Company's financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States)(the “PCAOB”), expressing an opinion as to the conformity of the financial statements with generally accepted accounting principles in the United States of America, and auditing management's assessment of the effectiveness of internal control over financial reporting. KPMG LLP has served as the Company's independent registered public accounting firm since 2005.

Management represented to the Audit Committee that the financial statements were prepared in accordance with generally accepted accounting principles and that there were no material weaknesses in its internal control over financial reporting. The Audit Committee met and held discussions with management and KPMG LLP to review and discuss the financial statements and the Company's internal control over financial reporting. The Audit Committee has also discussed with KPMG LLP the firm’s judgments as to the quality and the acceptability of the Company’s financial reporting and such other matters as are required to be discussed by PCAOB Auditing Standard No. 16, Communication with Audit Committees. KPMG LLP also provided the Audit Committee with the written disclosures and the letter required by applicable requirements of the PCAOB regarding the independent accountant's communications with the Audit Committee concerning independence. The Audit Committee has discussed with KPMG LLP their independence with respect to the Company, including a review of audit and non-audit fees and services and concluded that KPMG LLP is independent.

In fulfilling its oversight responsibilities for reviewing the services performed by KPMG LLP, the Audit Committee has the sole authority to select, evaluate and replace the outside auditors. The Audit Committee discusses the overall scope of the annual audit, the proposed audit fee, and annually evaluates the qualifications, performance and independence of KPMG LLP as independent registered public accountants and the performance of its lead audit partner. The Audit Committee meets regularly with the internal auditors and independent registered public accounting firm, with and without management present, to discuss the results of their respective examinations, the evaluation of the Company's internal control over financial reporting and the overall quality of the Company's accounting.

SECTION 2 - 2017 Compensation Decisions
Alignment of Pay and Performance

In 2017, the Company continued to pursue revenue and EPS growth, which is a key part of our strategy to promote long-term shareholder value in a competitive business environment. As the Compensation Committee reviewed our NEO's compensation, the Committee considered these aspects in conjunction with our executive compensation program of recognizing pay for performance through the following three primary components:
Base Pay+Cash Awards Under Our Annual Incentive Plan+Long-Term Incentives
Performance-Based RSUs
Time-Based RSUs
Cash LTIP

In recognition of the Company's 2017 performance, the successful integration of Health Net, the high growth rate over the past five years and the Board of Directors' acknowledgment of the importance of our CEO's leadership, the Compensation Committee analyzed our CEO's total historical compensation and awarded total compensation in 2017 that continues to mirror the overall growth in our Total Shareholder Return (TSR), revenue, diluted EPS and Adjusted Diluted EPS over the last five years (refer to Appendix A for reconciliation of non-GAAP measures included throughout this proxy statement). Our CEO's total compensation alignment with these metrics is illustrated in the following graphs:

Pay Mix

Our pay for performance philosophy can be further depicted by the following graph, which represents our total compensation mix. The graph below illustrates the 2017 values contained in the Summary Compensation Table as percentages of total compensation. The values in the “All Other Compensation” column of the Summary Compensation Table have been excluded from this illustration. 

chart-9068fdf1f3845e81c62.jpg

Target Pay Review

Consistent with our compensation philosophy, the Compensation Committee reviewed the target compensation and respective market data of two peer groups: General Industry (GI) and Healthcare Industry (HCI). The review of the data indicated that Mr. Neidorff's total target 2017 compensation was within the 50th percentile and 75th percentile of the GI, with data regressed at $60 billion and $70 billion in revenue, respectively. Our projected total revenues fall within this regression range.

While recognizing that Mr. Neidorff's total target compensation is above the 75th percentile of the HCI, the Compensation Committee determined that his target pay was appropriately established to reflect the need for an experienced, seasoned CEO in a high-growth company. The HCI peer group and GI peer group are discussed in further detail under Section 3 of the CD&A under the headings "Healthcare Industry Managed Care Peer Group" and "General Industry Group," respectively.

A similar analysis of peer data sets is performed of the other NEOs' compensation. The Compensation Committee reviews the performance of each individual and grants increases in base salary and Restricted Stock Units and Performance-Based Restricted Stock Units based on these results.

Base Salaries

In December 2016, the Compensation Committee evaluated 2017 base salaries and took into account the Company's 2017 estimated revenue in excess of $46 billion. In 2017, our NEOs' base salaries were compared to market data and, on average, the base salaries for 2017 approximated the 50th percentile of the healthcare industry peer group and the general industry peer group. Adjustments to base salaries are determined based on merit and market data.


Centene Corporation 29


2018 NOTICE OF MEETING AND PROXY STATEMENT
INFORMATION ABOUT EXECUTIVE COMPENSATION

The NEOs were paid competitive base salaries determined by the evaluation of multiple factors: business results for the prior year, individual performance, as well as the market value for each specific job. Since Centene is a pay for performance Company, only 6% of the Chief Executive Officer’s and, on average, 14% of the other NEOs' compensation is comprised of base salary.

Annual Cash Incentive Plan

The Compensation Committee assigned an annual cash incentive plan target opportunity of 150% of salary for the CEO and 100% of salary for the other NEOs based on a review of industry data, as discussed in Section 3: Compensation Philosophy. The Compensation Committee rewards NEOs with an annual cash incentive bonus if the Company achieves its EPS objective. The Committee assesses how each NEO contributed to achieving this EPS objective and other pre-determined objectives approved by the Compensation Committee earlier in the year. For 2017, the Committee determined that 70% of the incentive target will be aligned with the diluted EPS target, and the remaining 30% will be aligned with individual performance objectives, with a maximum payout of 200% of target. The Compensation Committee follows a two-step process to determine the bonus earned each year:

1.
Achievement of EPS Objective. In early 2017, the Compensation Committee determined that if the company reached its 2017 Adjusted Diluted EPS target of $4.60, then a bonus would be paid at target based on each NEO's contribution. Since the Company's 2017 Adjusted Diluted EPS from continuing operations was $5.03, the Compensation Committee determined to fund the incentive pool for NEOs up to the maximum of 200% of target.

2.
Evaluation of Individual Performance. In addition, based on input from management, the Compensation Committee assessed each NEO's individual performance against pre-determined goals. If the individual performance goals were met, exceeded or not met, then the individual performance component of the annual cash incentive equaled, exceeded or was less than the target. A summary of each NEO's individual performance, along with their total 2017 Annual Cash Incentive follows.

Long-Term Incentive Awards
The Compensation Committee granted long-term incentives to our NEOs in December 2017 based on a review of industry data, as follows:

Performance-based Restricted Stock Units (PSUs) (60% of equity granted) - The target metrics for the 2018 - 2020 performance period are pre-tax margin (60% weight) and compound annual revenue growth (40% weight). Threshold, target and maximum metric achievement will result in 50%, 100% and 200% attainment of the PSUs granted, respectively. If earned, PSUs will vest in February 2021.
Service-based Restricted Stock Units (RSUs) (40% of equity granted) - One-third vest annually based on service to the Company.
Cash Long-term Incentive Plan (Cash LTIP) - The target metrics include the performance criteria above for the three-year performance period (2018 - 2020) as well as a relative Total Shareholder Return objective.

2015-2017 Cash Long-Term Incentive Plan Award Performance

In December 2014, the Compensation Committee established the following metrics, targets and weights for the 2015 - 2017 Cash LTIP. The Compensation Committee has the discretion to evaluate the metrics on an "as adjusted" basis, and excluded certain one-time acquisition related transaction costs and the impact of the 2017 health insurer fee moratorium in evaluating the pre-tax margin metric criteria. The Company met or exceeded all three targets as shown below with a total percentage payout of 145.6% of the target:

SECTION 3 - Compensation Philosophy

The following principles guide the Company's compensation philosophy:

Pay for Performance - Our overall compensation philosophy is to pay for performance. An executive's compensation is directly linked to performance and the achievement of both Company and individual goals. Superior performance and the achievement of goals results in higher compensation.

Create Long-Term Stockholder Value - Both performance-based and service-based stock awards with meaningful retention requirements are used to encourage sustained stockholder value creation.

Foster a Culture of Risk Management and Compliance - A portion of NEO compensation is based on meeting individual goals that align with our corporate mission statement and promote a culture of compliance with rules, regulations and the Company's vision and values and rewarding those who mitigate business risks.

Attract and Retain Top Executive Talent - We offer competitive pay to attract, motivate and retain industry executives with the skills and experience to drive superior long-term Company performance in a high growth company.

Results of the April 2017 “Say-on-Pay” Vote

The Compensation Committee monitors the results of the annual advisory “say-on-pay” proposal and considers such results as one of many factors in connection with the discharge of its responsibilities. At our April 2017 Annual Meeting, approximately 89% of our stockholders voted to approve our fiscal 2016 executive compensation program.

Stockholders expressed a wide variety of views about executive compensation. We valued the insights we received from our institutional investors as we reached out to gain a more thorough understanding of their comments. As a result of feedback from our stockholders over the last few years, the Compensation Committee previously made key changes, including:

Aligned 70% of each NEO's annual incentive award to diluted EPS;
Changed the performance period applicable to PSUs from one-year to three-years; and
Changed the mix of PSUs and RSUs for executives from a 50/50% split to a 60/40% split, respectively.

We have also received some feedback that our equity grants as a percent of outstanding shares, which has trended around 1.4%, is higher than some investors prefer. While we recognize it is a higher rate than some of our competitors, we believe that providing broader ownership participation below senior leaders is important in driving company performance and retaining key talent.

ü

Competitive Compensation Each component of the NEOs' annual total direct compensation is targeted to the 50th percentile for both the Health Care Industry peer group and the General Industry peer group.

X
No Single-Trigger Employment Agreements Any cash payments in executive employment agreements are subject to a "double-trigger" change in control condition.

Competitive Pay Philosophy

Centene must leverage its compensation and benefit programs to attract the best talent to compete and achieve aggressive operating objectives. Therefore, Centene views both private equity firms and competitors with larger revenue bases as significant competition for talent. Centene also recognizes that our Company is a source for these firms and competitors to recruit talent if the appropriate compensation programs are not in place at Centene.

For the components of target total compensation, the Compensation Committee's competitive objectives are for:

base salaries to approximate the 50th percentile of similarly-sized organizations, based on revenues. The 50th percentile will be targeted in most instances; however, up to the 75th percentile or higher may be considered when retaining key employees and recruiting talent from significantly larger companies and private equity firms or when the experience of the executive dictates a higher base salary;
annual bonus targets to approximate the 50th percentile of similarly-sized organizations; and
long-term incentive targets to approximate the 50th percentile of similarly-sized organizations.

The goal of these objectives is that based on individual performance, actual total compensation will fall at the 50th percentile of total market based compensation for both the healthcare industry peer group and the general industry peer group for expected performance and between the 50th and 75th percentile based on extraordinary performance.

In order to achieve these objectives, the Compensation Committee establishes target, market-based total compensation levels (e.g., base salary, annual bonus target and long-term incentives) from market data from two different peer groups.

A. Healthcare Industry Managed Care Peer Group

Using the Standard and Poor's Global Industry Classification System (GICS) codes and other relevant industry parameters, Exequity, LLP analyzed the managed care industry and determined there are four key segments in the industry:

Managed Healthcare Companies;
Healthcare Services;
Healthcare Distributors; and
Healthcare Facilities.

B. General Industry Group

Since there is a market for executive talent both within and outside our industry, we also benchmark against the general industry. Therefore, the market data the Compensation Committee utilizes includes not only the managed healthcare industry peer group of 14 companies, plus a general industry peer group of approximately 400 companies developed by Willis Towers Watson's Compensation Database (CDB).

Benchmarking Methodology

The Compensation Committee engaged Exequity, LLP, to gather, analyze and summarize the market data from the Willis Towers Watson Executive Compensation Database for the CEO and the other four NEOs.

For this analysis, which is utilized in determining December equity grant awards and compensation for the forthcoming year, including base salaries, annual cash incentive targets and cash LTIP targets, we size adjust both the healthcare and general industry peer data to be in line with our forecasted revenues for the upcoming year. The Compensation Committee also reviews data adjusted to reflect the estimated revenues over the next one to three years, based on our growth pattern combined with any proposed acquisitions, and to provide a more representative depiction of the overall competitive market for talent, as evidenced by several of our executives who came from companies outside of our industry.

 All elements of compensation are valued and reviewed in evaluating the relative competitiveness of our compensation practices against both the market data and the Compensation Committee's competitive objectives. In addition, the Compensation Committee annually reviews a tally sheet for each NEO, which includes the current value of all outstanding equity-based awards, benefits and perquisites. The Compensation Committee uses the tally sheets to analyze each NEO's base salary, annual incentive target and long-term incentive opportunity in relation to the market and each component of compensation as a percentage of total compensation.

36 Centene Corporation

2018 NOTICE OF MEETING AND PROXY STATEMENT
INFORMATION ABOUT EXECUTIVE COMPENSATION


Base Salaries

While reviewing market data to determine appropriate annual base salaries, the Compensation Committee also considers:

the Chief Executive Officer's compensation recommendations for all other NEOs;
the scope of responsibility, experience, time in position and individual performance of each officer, including the Chief Executive Officer;
each executive's leadership performance and potential to enhance long-term stockholder value; and
internal equity.
Annual Cash Incentive

The Compensation Committee rewards NEOs with an annual cash incentive bonus for achieving the Company's EPS objective. The Committee assesses how each NEO contributed to achieving this EPS objective and other pre-determined objectives approved by the Compensation Committee in early February of the current year. The Compensation Committee follows a two-step process to determine the amount of bonus earned each year:

1.The Company must meet a specific EPS objective during the year before any payments may be made. If the Company does not meet its threshold performance, no payments are made. The Company has not reached its threshold EPS objective in certain years past and, accordingly, no annual bonuses were paid.

2.In addition, each NEOs' individual performance is assessed by Management and the Compensation Committee against the pre-determined objectives. If these pre-determined objectives were met, exceeded or not met, then the annual bonus could equal, exceed or be less than target, respectively.
Individual awards under our bonus plan are approved by the Compensation Committee based primarily upon:

business performance versus our business plan;
the effectiveness of each executive's leadership performance and potential to enhance long-term stockholder value;
targeted bonus amounts, which are based upon market data; and

TSR, revenue growth, and pre-tax operating margin targets as well as competitive market practices areamendment to the Current Charter that immediately declassifies the Board such that the terms of all used by the Compensation Committee in determining long-term incentives.

These long-term incentives take the form of the following:

PSUs that are based on meeting pre-determined performance targets (pre-tax margin and revenue growth), vestCompany’s current directors will end at the end2023 Annual Meeting of Stockholders (the 2023 Annual Meeting) and all director nominees will stand for election annually at and after the 2023 Annual Meeting (the Declassification Amendment).

At the Company’s 2022 Annual Meeting of Stockholders (the 2022 Annual Meeting), the Company’s stockholders adopted an amendment to the Current Charter providing for the rolling declassification of the Board over a three-year performance period.
RSUs that vest over three years.
Cash LTIP that is based on meeting three-year TSR, pre-tax margin and revenue growth metrics.
Stock Options which are granted on a limited basis and vest over three years.

Long-term incentives are provided both through equity (PSUs at 60% and RSUs at 40%) and cash, while ensuring Accordingly, the Current Charter provides that the maximum number of shares of common stock grantedBoard will remain classified, in any calendar year (excluding shares granted in connection with an acquisition) does not exceed a level associated with competitive practice.

Cash LTIP Award Performance Targets

The Compensation Committee utilizes the Cash LTIP, which is a three-year performance program, to complement the stock incentive plan, manage dilution and supplement the number of shares available under the Company's stock incentive plan. Each NEO is awarded a grant at the beginningAs part of the three-year cycle based on the following targets:

Chairman & CEO - 150% of Prior Year’s Annual Salary
Other NEOs - 100% of Prior Year’s Annual Salary
Cash awards are paid annually, if earned, after completion of each three-year performance cycle, and targets are announced annually prior to the beginning of each three-year year performance cycle.

The Compensation Committee sets performance targets at levels it believes to be rigorous and challenging. The performance criteria may include any of the metrics identified in the plan document. We believe the specific performance metrics related to the Cash LTIP plan and the range of awards related to the achievement of such measures are reflective of our overall business strategy and constitute confidential information. We believe disclosing such information would cause us competitive harm. The Compensation Committee may determine that the performance parameters used to measure the appropriate pay out include or exclude items which are deemed extraordinary. These items include but are not limited to those stated in the plan document.

INFORMATION ABOUT EXECUTIVE COMPENSATION


In order for a NEO to earn a Cash LTIP payout, at least one of the following metric thresholds must be achieved: pre-tax margin percentage, revenue compound annual growth rate percentage or TSR relative to the healthcare industry peer group. These metrics are applicable for the 2016 - 2018 cycle (awarded in December 2015), the 2017 - 2019 cycle (awarded in December 2016), and the 2018 - 2020 cycle (awarded in December 2017).

Other Benefits

We provide our NEOs with a defined contribution 401(k) retirement program which is the same program that is generally provided to all our employees. We also provide our NEOs with a non-qualified deferred compensation plan to make up for matching contributions that are capped by compensation limits imposed on qualified retirement plans under the Internal Revenue Code. We do not provide our NEOs with a defined benefit retirement program. We also do not provide retiree medical coverage to our NEOs, with the exception of Mr. Neidorff, as specified in his employment agreement.
With respect to most other benefits, the benefits provided to NEOs and other executive officers are comparable to those provided to the majority of salaried and hourly Company employees. We require all NEOs to have their tax returns prepared or reviewed by an independent certified public accounting firm. Due to this requirement, costs related to these services are paid by the Company. In addition, each NEO has the option to use a financial advisor for fees that do not exceed $15,000 annually, in total, for both tax preparation and financial advisement. These costs are also fully taxable to them and are not grossed up to cover any personal income tax liability.
The Board of Directors believes that additional security is required for the position of Chairman and Chief Executive Officer and other NEOs. Pursuant to a policy implemented by our Board, Mr. Neidorff is required to use Company provided aircraft for all air travel. We also have an aircraft time sharing agreement with Mr. Neidorff that permits him to reimburse us for incremental costs when he uses the aircraft for personal travel. In addition, we provide home security services to Mr. Neidorff. Mr. Neidorff's personal use of Company aircraft and home security services are fully taxable to him and are not grossed up to cover his personal income tax liability. Home security services are also provided to our NEOs, and these costs are also fully taxable to them and are not grossed up to cover any personal income tax liability.

SECTION 4 - Other Compensation Policies and Information
Stock Ownership Guidelines

We utilize stock ownership guidelines for our NEOs, corporate officers and Board. We believe that ownership of our stock helps align the interests of our executives and stockholders and encourages executives to act in a manner that is expected to increase stockholder value. The stock ownership guidelines for our officers are as follows:
Minimum Ownership Requirement as a Multiple of Base Salary
Chairman and Chief Executive Officer5x
President & Executive Vice Presidents2.5x
Senior Vice Presidents2x
Market & Specialty Company Presidents & other Corporate Executives1x

The Compensation Committee annually reviews the stock ownership levels of the Board and all officers. Future stock awards take into consideration the executive's level of attainment of the suggested stock ownership amount. The Compensation Committee may elect to award the annual incentive to an executive in stock instead of cash if the suggested stock ownership amount is not achieved.
Officers who fail to achieve these ownership levels may not be eligible to receive any stock-based awards until they achieve their required ownership level. Shares owned directly by the officer (including those held as a joint tenant or as tenant in common), unvested RSUs, shares owned in a self-directed IRA, “phantom shares” held in the deferred compensation plan and certain shares owned or held for the benefit of a spouse or minor children are counted toward the guidelines. Options and unearned PSUs are not counted toward the ownership guidelines.

The Board has established a policy requiring executive officers to retain ownership of the shares received from the vesting or payout of any RSU award granted under our stock incentive plan (net of any shares used to satisfy tax obligations) for one year following such vesting or payout. An executive may substitute the tax basis of the shares under restriction for other shares held outright.

As of the close of the last fiscal year and the date of this report, all NEOs subject to the ownership guidelines are in compliance with the guidelines. At $100.88 per share (the December 31, 2017 closing stock price), our executive officers held Company stock as of a multiple of their 2017 base salaries as follows:

Our stock ownership guidelines for members of our Board require them to own 40,000 shares of common stock within 5 years of being appointed to the Board. As of December 31, 2017, all directors were in compliance with this requirement.

Pledging Policy

The Board maintains the Company's insider trading policy, which prohibits pledging of shares by executive officers and members of the Board. As of February 23, 2018, all executive officers and directors were in compliance with this policy.

Risk Disclosure

The Compensation Committee is aware of the consequences to companies that have not appropriately balanced risk and rewards in executive compensation. The Compensation Committee believes that the emphasis on long-term performance in the stock incentive plan and the Cash LTIP results in an overall compensation program that does not reward excessive risk-taking for the Company. Risk is further limited by the ownership guidelines mentioned previously and a clawback provision that provides that any cash bonuses that are paid from the annual incentive plan, Cash LTIP or vesting of PSUs that are a result of material financial impropriety (as defined by the Audit Committee of the Board), including but not limited to financial restatements due to these improprieties, may result in any officers becoming obligated to pay back the amount to the Company.

The Company's compensation strategy is intended to mitigate risk by emphasizing long-term compensation and financial performance measures correlated with growing stockholder value rather than rewarding shorter performance and payout periods. A recentBoard’s ongoing review of the Company's compensation programs by Exequity, LLP did not identify any programs that unduly incentivize employees to take any excessive risks.

Employment Contracts, Termination of Employment Arrangements, Change in Control Arrangements, and Retirement Provisions

The health and welfare benefits that Mr. Neidorff or his spouse would be entitled to, if he is terminated without cause or for good reason, were commitments made in his original employment agreement in 2004. Upon a change in control during the term of this agreement, any existing equity awards held by Mr. Neidorff will vest in full.

Severance and Change in Control Agreements

Cynthia J. Brinkley, Jesse N. Hunter, Jeffrey A. Schwaneke and Keith H. Williamson serve as executive officers pursuant to executive severance and change in control agreements (the agreements, as amended), and their 2018 annual salaries are $850,000, $725,000, $800,000 and $650,000, respectively.

The agreements generally provide that, if within 24 months following a change in control (as defined in the agreements), the executive's employment is terminated by the Company other than for cause (as defined in the agreements) or by the executive for good reason (as defined in the agreements), the executive will receive a lump sum cash payment equal to the sum of (1) an amount equal to 24 months of salary, (b) the average of the executive's last two annual bonuses multiplied by two, and (c) a prorated annual bonus for the year in which the termination occurs.

In the agreements, the executives agree to non-competition and non-solicitation provisions that extend through the first anniversary of termination of employment, unless the termination was due to a change in control as defined in the agreement. In 2012, the agreements were amended to eliminate the non-compete and non-solicitation provisions under any change in control.

Retirement ProvisionsProposal Two: The Special Meeting Proposal

The Company’s stockholders are being asked to consider and vote on the Special Meeting Proposal, which is a proposal to adopt an amendment to the Current Charter to eliminate the prohibition on stockholders calling special meetings (the Special Meeting Amendment).
In October of 2016,
The Current Charter prohibits stockholders from calling special meetings. At the Compensation Committee2022 Annual Meeting, Company stockholders approved a prospective qualified retirement definition fornonbinding stockholder proposal “to amend the appropriate company governing documents to give the owners of a combined 10% of our outstanding common stock awards. Employees who are at least 55 yearsthe power to call a special shareholder meeting.”

The Board recognizes that some stockholders feel the right of age and have 10 yearsstockholders to call a special meeting is an important corporate governance practice. As part of employmentthe Board’s ongoing review of the Company’s corporate governance practices, the Board considered this stockholder feedback, including through the approval of the stockholder proposal at the time2022 Annual Meeting, and has determined that it is in the best interests of retirement are eligible for the following:Company and its stockholders that the Current Charter’s prohibition on stockholders calling special meetings be removed. Accordingly, the Board has adopted and declared advisable the Special Meeting Amendment.

A pro-ratedThe Board believes that special meetings should be extraordinary events, held only if a significant number of PSUs vesting at the endstockholders agree that a special meeting is necessary to discuss critical, time-sensitive issues. In consideration of the performance period, based onSpecial Meeting Amendment, the Board considered the disruption that special meetings cause and the substantial costs they entail. Specifically, the Board, management and employees would be required to devote a significant amount of time employed duringand attention to preparing for a special meeting, which would distract them from their primary focus of managing our business for the performance periodlong-term benefit of our stockholders. In addition, with each special meeting, we must incur significant expenses in order to prepare the disclosures required for such meeting, print and actual performance outcomes.distribute materials, solicit proxies and tabulate votes. Therefore, the Board believes that, although a significant number of stockholders should have the right to call a special meeting, it is important that such right is exercised in accordance with terms and conditions that balance the foregoing considerations and establish an orderly and consistent process that provides fairness and transparency.

For these reasons, the Board, concurrently with its adoption of the Special Meeting Amendment, approved an amendment to the Company’s Amended and Restated By-Laws (the Current By-Laws) that would provide a stockholder, or a group of stockholders, holding at least 10% of the outstanding shares of our common stock to call a special meeting, subject to certain terms and conditions (the Special Meeting By-Laws Amendment). Such terms and conditions include, but are not limited to, the following:

To ensure adequate underlying support before committing Company resources, the By-Laws will require that stockholders seeking to call a special meeting must own, individually or in the aggregate, at least 10% of our outstanding shares of common stock to request that the Board set a record date to call a special meeting. This 10% ownership threshold is the same ownership threshold proposed in our Action by Written Consent Proposal, which the Board believes is appropriate so that a limited group of stockholders cannot use written consent to push forward an action that lacks sufficient support to merit calling a special meeting. The Board believes that this 10% threshold, which is consistent with market practice, permits stockholders to call a special meeting that has achieved a critical mass of support.

Any special meeting request must set forth information regarding the business proposed to be conducted at the special meeting and information regarding the requesting stockholder(s) that is similar to the information currently required by our By-laws in order for a stockholder to nominate directors or propose business at our annual meetings.

The Board will not be required to hold a special meeting if:

The business requested to be conducted at the special meeting is not a proper subject for stockholder action under applicable law or that involves a violation of applicable law;

The Company’s stockholders are being asked to consider and vote on the Action by Written Consent Proposal, to adopt an amendment to the Current Charter to grant stockholders the right to act by written consent, subject to certain terms and conditions (the Action by Written Consent Amendment).
Section 162(m)(6), which was enacted as
The Current Charter prohibits stockholders from acting by written consent.

The Board recognizes that some stockholders feel the right of stockholders to act by written consent is an important corporate governance practice. As part of the Patient Protection and Affordable Care Act, amended the Code to limit the amount that certain healthcare insurers and providers, including the Company, may deduct for compensation to any employee in excess of $500,000 for a tax year beginning after December 31, 2012. This legislation does not create any exceptions for performance-based compensation and is not otherwise impacted by the adoptionBoard’s ongoing review of the Tax CutsCompany’s corporate governance practices, the Board considered this stockholder feedback and Jobs Act enacted on December 22, 2017. The Compensation Committee reserves the right to use its judgment to authorize compensation paymentshas determined that may be subject to the limit when the Compensation Committee believes such payments are appropriate andit is in the best interests of ourthe Company and its stockholders after taking into consideration changing business conditionsthat the Current Charter be amended to permit stockholders to act by written consent. However, the Board also believes that reasonable safeguards should be included to enhance transparency and prevent the disenfranchisement of minority stockholders and the performanceinefficient use of its employees. We were subjectcorporate resources.

For these reasons, the Board adopted and declared advisable the Action by Written Consent Amendment, which would permit Company stockholders to act by written consent in accordance with certain terms and conditions that balance the foregoing considerations and establish an orderly and consistent process that provides fairness, transparency and a deliberative process. Such terms and conditions include, but are not limited to, the limitationfollowing:

To ensure adequate underlying support before committing Company resources to the consent solicitation process, the Charter will require that stockholders seeking to act by written consent must own, individually or in 2017.the aggregate, at least 10% of our outstanding shares of common stock to request that the Board set a record date to determine the stockholders entitled to act by written consent. This 10% ownership threshold is the same ownership threshold proposed in our Special Meeting Proposal, which the Board believes is appropriate so that a limited group of stockholders cannot use written consent to push forward an action that lacks sufficient support to merit calling a special meeting. The Board believes that this 10% threshold, which is consistent with market practice, permits stockholders to initiate action around a matter that has achieved a critical mass of support.

To ensure that all stockholders have a voice, stockholders that seek to act by written consent must solicit written consents from all stockholders entitled to vote on the matter, giving each stockholder the right to consider and act on the proposal, similar to what would be done at a stockholder meeting. This protection eliminates the possibility that a small group of stockholders could act without a democratic process for determining the merits of any proposed action.

To ensure transparency, stockholders that seek to act by written consent must provide the Company with similar information that would be required to propose such action at a stockholder meeting.

To provide the Board with sufficient time to evaluate and respond to a valid stockholder request for a record date, the Board must act and fix a record date by the later of (i) ten (10) days after delivery of such request and (ii) five (5) days after delivery by the stockholders of any information requested by the Company to determine the validity of such request. The record date must be no more than ten days after the date on which the resolution fixing the record date is adopted.

To provide stockholders with sufficient time to consider the proposal, as well as to provide the Board the opportunity to present its views regarding the proposed action, no executed consents may be delivered until sixty (60) days after the delivery of a valid request to set a record date.

To protect against duplicative matters or other abuses, the Charter will provide that the written consent process is not available in a limited number of circumstances, including:

The business requested to be conducted through written consent is not a proper subject for stockholder action under applicable law;

If the Adjournment Proposal is approved, the Special Meeting could be adjourned to a later date. The Company could adjourn the Special Meeting and any adjourned session of the Special Meeting and use the additional time to solicit additional proxies, including the solicitation of proxies from Company stockholders who have previously voted.

If the Special Meeting is adjourned, Company stockholders who have already submitted their proxies will be able to revoke them at any time prior to their use. If you sign and return a proxy and do not indicate how you wish to vote on any proposal, or if you indicate that you wish to vote in favor of the Declassification Proposal, the Special Meeting Proposal or the Action by Written Consent Proposal but do not indicate a choice on the Adjournment Proposal, your shares will be voted in favor of the Adjournment Proposal. If you indicate, however, that you wish to vote against each of the Declassification Proposal, the Special Meeting Proposal or the Action by Written Consent Proposal, your shares of our common stock will only be voted in favor of the Adjournment Proposal if you indicate that you wish to vote in favor of the Adjournment Proposal.

Whether or not a quorum is present, approval of the Adjournment Proposal requires the affirmative vote of a majority of the votes cast and entitled to vote thereon at the Special Meeting.

The Board recommends a vote “FOR” the Adjournment Proposal.

The amounts reported as Stock Awards and Option Awards for Mr. Neidorff, Mr. Schwaneke, Ms. Brinkley, Mr. Hunter and Mr. Williamson reflect the grant date fair value of grants made during the current year under the 2012 Stock Incentive Plan in accordance with ASC 718.

Assumptions used in the calculation of these amounts for the fiscal year ended December 31, 2017 are included in footnote 15 to the Company's audited financial statements for the fiscal year ended December 31, 2017, included in the Company's Annual Report on Form 10-K filed with the SEC on February 20, 2018. There can be no assurance that the grant date fair value of stock awards will ever be realized. Stock awards granted in December 2017, 2016, and 2015 to the NEOs consisted of performance-based awards and service-based awards. If the maximum performance metrics are achieved, the grant date fair value of the December 2017 performance awards would be $19,365,120 for Mr. Neidorff, $3,589,200 for Mr. Schwaneke, $4,307,040 for Ms. Brinkley, $2,512,440 for Mr. Hunter and $849,444 for Mr. Williamson. The Summary Compensation Table reflects the probable amount of shares to be earned under the performance condition.
2The amounts shown in the Non-Equity Incentive Plan Compensation column include both the annual cash incentive and the Cash LTIP award payouts.
3The amounts shown in the All Other Compensation column for Mr. Neidorff include $168,605 of personal use of Company provided aircraft. Pursuant to the policy established by our Board, our Chairman and Chief Executive Officer is required to use Company provided aircraft for all travel, a taxable benefit to Mr. Neidorff pursuant to the applicable Internal Revenue Service regulations. For flights on corporate aircraft, the cost is calculated based on a cost-per-flight-hour charge developed by a nationally recognized and independent service and excludes any timeshare payments by the executive. This charge reflects the operating and periodic maintenance costs of the aircraft, crew travel expenses and other miscellaneous costs. We have an aircraft time sharing agreement with Mr. Neidorff under which he is permitted to reimburse us for the incremental costs of his personal use of corporate aircraft consistent with FAA regulations. The other amounts included in other compensation for Mr. Neidorff include $151,214 in life insurance benefits, $153,485 in nonqualified deferred compensation match, as well as security services, tax preparation and financial advisor fees, Company entertainment event tickets, and 401(k) match.
4The amounts shown in the All Other Compensation Column for NEOs other than Mr. Neidorff include nonqualified deferred compensation match, $8,100 for 401(k) match, tax preparation and financial advisor fees, security services, as well as life insurance benefits. The other amounts included in other compensation for Mr. Schwaneke, Ms. Brinkley, Mr. Hunter and Mr. Williamson include $45,628, $45,459, $38,338 and $32,516, respectively, in nonqualified deferred compensation match. Ms. Brinkley's other compensation also includes personal use of Company provided aircraft valued as described in footnote 3.

2All registrant contributions are included in the All Other Compensation column in the Summary Compensation Table.
3The Company does not pay above market interest or preferential dividends on investments in the Deferred Compensation Plan. Investment options in the Deferred Compensation Plan are substantially the same as the 401(k) plan, with the exception of the investment in Centene common stock. The returns on the investments available to employees during 2017 ranged from 0% to 79%, with a median return of 22% for the year ended December 31, 2017.
4The amounts shown in the Aggregate Balance at Last Fiscal Year-End column include money the Company owes these individuals for salaries and incentive compensation they earned in prior years but did not receive because they elected to defer receipt of it and save it for retirement. For fiscal 2017, the amounts described in Footnote 1 above are included in the Summary Compensation Table as described in footnote 1. For fiscal 2016, the following aggregate amounts of executive contributions were included in the Summary Compensation Table: Mr. Neidorff - $306,000; Mr. Schwaneke - $37,904; Ms. Brinkley - $140,000; Mr. Hunter - $95,700; Mr. Williamson - $201,806. For fiscal 2015, the following aggregate amounts of executive contributions were included in the Summary Compensation Table: Mr. Neidorff - $288,069; Mr. Hunter - $87,305. For prior years, all amounts contributed by a NEO in such years have been reported in the Summary Compensation Table in our previously filed proxy statements in the year earned, to the extent the executive was named in such proxy statements and the amounts were so required to be reported in such tables.
5Pursuant to the terms of the grant agreement, the receipt of 2,000,000 RSUs that vested from 2009 through 2014 has been deferred until retirement. The total value of the RSUs is reflected in the aggregate balance based on the December 31, 2017 market value.

Potential Payments Upon Termination or Change in Control

The section below describes the payments that may be made to our NEOs upon termination or a change in control. Generally, pursuant to our executive agreements, a change in control is deemed to occur:

If any individual, entity or group (other than a group which includes the executive) acquires 40% or more of the voting power of our outstanding securities;
If a majority of the incumbent Board of Directors are replaced. For these purposes, the incumbent Board of Directors means the directors who were serving as of the effective date of the applicable executive agreement and any individual who becomes a director subsequent to such date whose election or nomination for election was approved by a majority of such directors, other than in connection with a proxy contest; or
Upon the consummation of a merger or consolidation of the Company with another person, other than a merger or consolidation where the individuals and entities who were beneficial owners, respectively, of our outstanding voting securities immediately prior to such merger or consolidation own 50% or more of the then-outstanding shares of the combined voting power of the then-outstanding voting securities of the corporation resulting from such merger or consolidation.
The amounts presented below assume the termination or change in control occurred as of December 31, 2017. The NEOs would receive other payments and benefits to which they were already entitled or vested on such date, including amounts under the Deferred Compensation Plan under the 'Nonqualified Deferred Compensation Table'. The applicable agreements are discussed in the CD&A under the heading “Employment Contracts, Termination of Employment Arrangements, Change in Control Arrangements, and Retirement Provisions” included in this proxy statement. The change in control cash payments are subject to the conditions of the "double-trigger" criteria in each of the NEO's employment agreements. The equity award acceleration amounts below were calculated using the closing price of our common stock on December 31, 2017 of $100.88. Cash LTIP and PSU awards prior to 2016 are included in the tables based upon the target level of performance. Cash LTIP and PSU awards granted in 2016 and 2017 are included at the greater of the target or actual level of performance as of December 31, 2017.

2018 NOTICE OF MEETING AND PROXY STATEMENT
INFORMATION ABOUT EXECUTIVE COMPENSATION

CEO to Median Employee Pay Ratio Information

Pursuant to Item 402(u) of Regulation S-K, we have included below a disclosure of the ratio of the median employee’s annual total compensation to the annual total compensation of our Chief Executive Officer, Mr. Neidorff. Because the applicable SEC rules allow companies to use a variety of methods to determine this ratio, the ratio disclosed by the Company may not be comparable to the ratio disclosed by other companies.

Mr. Neidorff's annual total compensation for the year ended December 31, 2017 was $25,269,468, which reflects the amount reported in the Summary Compensation Table of this proxy statement plus $10,000 of the company-paid portion of Mr. Neidorff’s medical plan premiums. The annual total compensation for the median employee for the year ending December 31, 2017 was $66,600, inclusive of the company-paid portion of the medical plan premiums. Mr. Neidorff's annual total compensation was 379 times that of our median employee's pay.

In determining the median employee, we examined total cash compensation (i.e. base wages plus short-term incentive payments) for individuals, excluding our CEO, who were employed by the company as of December 31, 2017. During this analysis, the compensation for employees hired during the year was annualized. We included all employees, whether employed on a full-time, part-time or temporary basis, except approximately 505 employees in the United Kingdom which were excluded under the de minimis exemption and 231 employees related to an acquisition that closed in the fourth quarter of 2017. This resulted in 33,312 employees being included in our median employee calculation.

After identifying the median employee, we calculated annual total compensation of the employee using the same methodology used for our NEOs within the Summary Compensation Table of this proxy statement, plus company-paid medical plan premiums capped at $10,000.

APPENDIX A

(b) The number of directors of the Corporation shall be as from time to time fixed by the Board of Directors, within any limitations as may be fixed by the By-Laws. Election of directors need not be by written ballot unless the By-Laws so provide.

(c) Until the conclusion of the Corporation's 2025The term of office of all directors serving as of the effective date of this Certificate of Incorporation shall expire at the 2023 annual meeting of stockholders (the "2025 Annual Meeting"), the directors shall be divided into three classes, designated Class I, Class II and Class III. Each class shall consist, as nearly as may be possible, of one-third of the total number of directors constituting the entire Board of Directors. Each person elected as a director of the Corporation at or after the annual meeting of stockholders that is held in calendar year 2023 (the "2023 Annual Meeting"), whether to succeed a person whose term of office as a director has expired or to fill any vacancy, shall be elected for a term expiring at the next annual meeting of stockholders. Each director elected prior to the 2023 Annual Meeting shall continue to serve as a director for the term for which he or she was elected. In each case, each director shall hold office until such director's successor shall is duly elected and qualified, or until such director's earlier death, resignation, retirement, disqualification or removal from office.

(d) Subject to the terms of any one or more classes or series of Preferred Stock, any vacancy on the Board of Directors that results from an increase in the number of directors may be filled by a majority of the Board of Directors then in office,; provided that a quorum is present, and any other vacancy occurring on the Board of Directors may be filled by a majority of the Board of Directors then in office, even if less than a quorum, or by a sole remaining director. Any director elected to fill a vacancy shall hold office for a term expiring at the next annual meeting of stockholders. Subject to the rights, if any, of the holders of shares of Preferred Stock then outstanding, any or all of the directors of the Corporation may be removed from office at any time, with or without cause, by the affirmative vote of the holders of at least a majority of the voting power of the Corporation's then issued and outstanding capital stock entitled to vote generally in the election of directors; provided, however, any director elected prior to the 2025 Annual Meeting and any director appointed to fill a vacancy of any director elected prior to the 2025 Annual Meeting may be removed from office only for cause by the affirmative vote of the holders of at least a majority of the voting power of the Corporation's then issued and outstanding capital stock entitled to vote generally in the election of directors. Notwithstanding the foregoing, whenever the holders of any one or more classes or series of Preferred Stock issued by the Corporation shall have the right, voting separately by class or series, to elect directors at an annual or special meeting of stockholders, the election, term of office, filling of vacancies and other features of such directorships shall be governed by the terms of this Certificate of Incorporation applicable thereto.

(e) In addition to the powers and authority hereinbefore or by statute expressly conferred upon them, the directors are hereby empowered to exercise all such powers and do all such acts and things as may be exercised or done by the Corporation, subject, nevertheless, to the provisions of the GCL, this Certificate of Incorporation, and any By-Laws adopted by the stockholders; provided, however, that no By-Laws hereafter adopted by the stockholders shall invalidate any prior act of the directors which would have been valid if such By-Laws had not been adopted.

SIXTH: No director shall be personally liable to the Corporation or any of its stockholders for monetary damages for breach of fiduciary duty as a director, except to the extent such exemption from liability or limitation thereof is not permitted under the GCL as the same exists or may hereafter be amended. If the GCL is amended hereafter to authorize the further elimination or limitation of the liability of directors, then the liability of a director of the Corporation shall be eliminated or limited to the fullest extent authorized by the GCL, as so amended. Any repeal or modification of this Article SIXTH by the stockholders of the Corporation shall not adversely affect any right or protection of a director of the Corporation existing at the time of such repeal or modification with respect to acts or omissions occurring prior to such repeal or modification.

SEVENTH: The Corporation shall indemnify its directors and officers to the fullest extent authorized or permitted by law, as now or hereafter in effect, and such right to indemnification shall continue as to a person who has ceased to be a director or officer of the Corporation and shall inure to the benefit of his or her heirs, executors and personal and legal representatives; provided, however, that, except for proceedings to enforce rights to indemnification, the Corporation shall not be obligated to indemnify any director or officer (or his or her heirs, executors or personal or legal representatives) in connection with a

APPENDIX A
proceeding (or part thereof) initiated by such person unless such proceeding (or part thereof) was authorized or consented to by the Board of Directors. The right to indemnification conferred by this Article SEVENTH shall include the right to be paid by the Corporation the expenses incurred in defending or otherwise participating in any proceeding in advance of its final disposition.

The Corporation may, to the extent authorized from time to time by the Board of Directors, provide rights to indemnification and to the advancement of expenses to employees and agents of the Corporation similar to those conferred in this Article SEVENTH to directors and officers of the Corporation.

The rights to indemnification and to the advance of expenses conferred in this Article SEVENTH shall not be exclusive of any other right which any person may have or hereafter acquire under this Certificate of Incorporation, the By-Laws of the Corporation, any statute, agreement, vote of stockholders or disinterested directors or otherwise.

Any repeal or modification of this Article SEVENTH by the stockholders of the Corporation shall not adversely affect any rights to indemnification and to the advancement of expenses of a director or officer of the Corporation existing at the time of such repeal or modification with respect to any acts or omissions occurring prior to such repeal or modification.

The ability of the stockholders to call a special meeting is hereby specifically denied.
NINTH: Reserved.

TENTH: Any action required or permitted to be taken by the stockholders of the Corporation must be effected at a duly called annual or special meeting of stockholders of the Corporation, and the ability of the stockholders to consent in writing to the taking of any action is hereby specifically denied.
TENTH:

(a) All actions required or permitted to be taken by stockholders at an annual or special meeting of stockholders (a "Corporate Action") may be taken without a meeting, without prior notice and without a vote, if a written consent or consents, setting forth the Corporate Action so taken, shall be signed by the holders of outstanding capital stock of the Corporation having not less than the minimum number of votes that would be necessary to authorize or take such a Corporate Action at a meeting at which all shares entitled to vote thereon were present and voted, in each case, in accordance with the GCL and this Certificate of Incorporation (such written consent or consents, a "Written Consent"); provided, however, that no Corporate Action by Written Consent may be taken except in accordance with the provisions of this Article TENTH and applicable law.

(b) The record date for determining stockholders entitled to effect a Corporate Action by Written Consent shall be as fixed by the Board of Directors or as otherwise established under this Article TENTH. Any stockholder seeking to have the stockholders take a Corporate Action by Written Consent shall request that a record date be fixed for such purpose by written notice addressed and delivered to the secretary of the Corporation and signed by a stockholder or stockholders holding ten percent (10%) or more of the voting power of the shares of capital stock entitled to vote on such Corporate Action. The written notice must contain the information set forth in paragraph (c) of this Article TENTH. Following delivery of this notice, the Board of Directors shall, by the later of (i) ten (10) days after delivery of a valid request to set a record date and (ii) five (5) days after delivery of any information requested by the Corporation to determine the validity of the request for a record date or to determine whether the Corporate Action to which the request relates may be taken by Written Consent pursuant to this Article TENTH, determine the validity of the request and whether the request relates to a Corporate Action that may be taken by a Written Consent pursuant to this Article TENTH, and, if appropriate, adopt a resolution fixing the record date for such purpose. The record date for such purpose shall be no more than ten (10) days after the date upon which the resolution fixing the record date is adopted by the Board of Directors and shall not precede the date such resolution is adopted. If the Board of Directors determines that such request is valid and relates to a

APPENDIX A
Corporate Action that may be taken by a Written Consent pursuant to this Article TENTH or if no such determination shall have been made by the date required by this Article TENTH, and in either event no record date has been fixed by the Board of Directors, the record date shall be the first date on which a signed Consent (as defined in paragraph (f) of this Article TENTH) relating to the proposed Corporate Action is delivered to the Corporation in accordance with paragraph (g) of this Article TENTH; provided that, if prior action by the Board of Directors is required under the provisions of the GCL, the record date shall be at the close of business on the day on which the Board of Directors adopts the resolution taking such prior action.

(c) Any notice required by paragraph (b) of this Article TENTH (i) must describe the Corporate Action proposed to be taken by Written Consent and (iii) must contain (A) such information and representations, to the extent applicable, then required by Article II Section 7, Article III, Section 2 or any other applicable sections of the Corporation’s By-Laws as though such stockholder was intending to make a nomination or to bring any other matter before a meeting of stockholders and (b) the text of the proposal(s) (including the text of any resolutions to be adopted by Written Consent and the language of any proposed amendment to the By-Laws of the Corporation). The Corporation may require the stockholder(s) submitting such notice to furnish such other information as may be requested by the Corporation to determine the validity of the request for a record date and to determine whether the request relates to a Corporate Action that may be taken by Written Consent under this Article TENTH. In connection with any Corporate Action proposed to be taken by Written Consent in accordance with this ArticleTENTH, the stockholders seeking such Corporate Action by Written Consent shall further update and supplement the information previously provided to the Corporation in connection therewith, if necessary, as required by Article II Section 7, Article III, Section 2 or any other applicable section of the Corporation’s By-Laws

(d) Stockholders are not permitted to take a Corporate Action by Written Consent if:

(i) such Corporate Action relates to an item of business that is not a proper subject for stockholder action under applicable law;

(ii) the request for a record date for such Corporate Action by Written Consent is received by the Corporation during the period commencing ninety (90) days prior to the first anniversary of the date of the immediately preceding annual meeting of stockholders and ending on the date of the next annual meeting of stockholders;

(iii) an annual or special meeting of stockholders that included an item of business substantially the same as, or substantially similar to, such Corporate Action (a “Similar Item”) was held not more than one hundred twenty (120) days before such request for a record date was received by the secretary of the Corporation;

(iv) a Similar Item is to be included in the Corporation’s notice as an item of business to be brought before a meeting of stockholders that is to be called within forty (40) days after the request for a record date is received and held as soon as reasonably practicable thereafter; or

(v) such record date request was made in a manner that involved a violation of Regulation 14A under the Securities Exchange Act of 1934 (the “Exchange Act”) or other applicable law.

For purposes of this paragraph (d), the nomination, election or removal of directors shall be deemed to be a Similar Item with respect to all actions involving the nomination, election or removal of directors, changing the size of the Board of Directors and filling of vacancies and/or newly created directorships resulting from any increase in the authorized number of directors.

The Board of Directors shall determine in good faith whether a record date is required to be set under the provisions of this Article TENTH.

(e) Stockholders may take a Corporate Action by Written Consent only if consents are solicited by the stockholder or group of stockholders seeking to take such Corporate Action by Written Consent from all

APPENDIX A
holders of capital stock of the Corporation entitled to vote on such Corporate Action pursuant to a consent solicitation conducted pursuant to Regulation 14A of the Exchange Act, without reliance upon the exemption contained in Rule 14a‑2(b)(2) of the Exchange Act and in accordance with this Article TENTH and applicable law.

(f) Every written consent purporting to take or authorize the taking of Corporate Action by Written Consent (each such written consent, a “Consent”) must bear the date of signature of each stockholder who signs the Consent, and no Consent shall be effective to take the such CorporateAction unless, within sixty (60) days of the earliest dated Consent delivered to the Corporation in the manner required by paragraph (g) of this Article TENTH and not later than one hundred twenty (120) days after the record date, Consents signed by a sufficient number of stockholders to take such Corporate Action are so delivered to the secretary of the Corporation.

(g) No Consents may be delivered to the Corporation until fifty (50) days after the record date. Consents must be delivered to the Corporation by delivery to the Corporation’s secretary at the Corporation’s principal place of business. Delivery must be made by hand or by certified or registered mail, return receipt requested. In the event of the delivery to the Corporation of Consents, the secretary of the Corporation, or such other officer of the Corporation as the Board of Directors may designate, shall provide for the safe‑keeping of such Consents and any related revocations and shall promptly conduct such ministerial review of the sufficiency of all Consents and any related revocations and of the validity of the Corporate Action to be taken by Written Consent as the secretary of the Corporation, or such other officer of the Corporation as the Board of Directors may designate, as the case may be, deems necessary or appropriate, including, without limitation, whether the stockholders of a number of shares having the requisite voting power to authorize or take the Corporate Action specified in such Consents have delivered Consent thereto; provided, however, that if the Corporate Action to which the Consents relate is the removal or replacement of one or more members of the Board of Directors, the secretary of the Corporation, or such other officer of the Corporation as the Board of Directors may designate, as the case may be, shall promptly designate one (1) person, who shall not be members of the Board of Directors, to serve as inspector (“Inspector”) with respect to such Consents and such Inspector shall discharge the functions of the secretary of the Corporation, or such other officer of the Corporation as the Board of Directors may designate, as the case may be, under this Article TENTH. If, after such investigation, the secretary of the Corporation, such other officer of the Corporation as the Board of Directors may designate or the Inspector, as the case may be, shall determine that the Corporate Action purported to have been taken is duly authorized by the Consents, that fact shall be certified on the records of the Corporation kept for the purpose of recording the proceedings of meetings of stockholders and the Consents shall be filed in such records. In conducting the investigation required by this section, the secretary of the Corporation, such other officer of the Corporation as the Board of Directors may designate or the Inspector, as the case may be, may, at the expense of the Corporation, retain special legal counsel and any other necessary or appropriate professional advisors as such person or persons may deem necessary or appropriate and, to the fullest extent permitted by law, shall be fully protected in relying in good faith upon the opinion of such counsel or advisors.

(h) If the Board of Directors shall determine that any request to fix a record date or to take a Corporate Action by Written Consent was not properly made in accordance with, or relates to a Corporate Action that may not be taken by Written Consent pursuant to, this Article TENTH, or the stockholder or stockholders seeking to take such Corporate Action do not otherwise comply with this Article TENTH, then the Board of Directors shall not be required to fix a record date and any such purported Corporate Action by Written Consent shall be null and void to the fullest extent permitted by applicable law. No Corporate Action by Written Consent shall be effective until such date as the secretary of the Corporation, such other officer of the Corporation as the Board of Directors may designate or the Inspector, as the case may be, certify to the Corporation that the Consents delivered to the Corporation in accordance with paragraph (g) of this ArticleTENTH represent not less than the minimum number of votes that would be necessary to authorize or take such Corporate Action at a meeting at which all shares of capital stock entitled to vote thereon were present and voted, in each case, in accordance with the GCL and this Certificate of Incorporation.
