PROPOSAL 1—ELECTION OF DIRECTORS

WHAT YOU ARE VOTING ON:

At the 2018 Annual Meeting, three Class III directors are to be elected to hold office until the 2021 Annual Meeting and until their successors are elected and qualified, or until the directors either resign or are removed from office.

The Company's Board of Directors currently consists of nine members and is divided into three classes serving terms of three years. Stockholders elect one class of directors at each annual meeting. The class up for election at the 2018 Annual Meeting is Class III, whose members currently include Thomas D. Carey, Daniel J. Levangie and Michael S. Wyzga. Upon the recommendation of the Corporate Governance and Nominating Committee of our Board of Directors, our Board of Directors has nominated and recommended Thomas D. Carey, Daniel J. Levangie and Michael S. Wyzga for re-election to our Board of Directors as Class III directors.

Shares represented by all proxies received by our Board of Directors and not marked so as to withhold authority to vote for any individual nominee will be voted FOR the election of the nominees named below. Our Board of Directors knows of no reason why any nominee would be unable or unwilling to serve, but if such should be the case, proxies may be voted for the election of some other person nominated by our Board of Directors.

The Company's Corporate Governance Guidelines provide for a majority voting policy in uncontested elections of nominees to our Board of Directors. Under the majority voting policy, any nominee for director in an uncontested election who receives a greater number of votes "withheld" from his or her election than votes "for" such election must offer his or her resignation as a director to the Corporate Governance & Nominating Committee of our Board of Directors. Upon receipt of this offer of resignation, the Corporate Governance & Nominating Committee will consider the offer of resignation and recommend to our Board of Directors action to be taken with respect to the offer of resignation, including whether or not to accept such offer of resignation. Our Board of Directors will then act upon such recommendation and promptly disclose its decision, together with an explanation of the reasons behind such decision. Our majority voting policy is set forth in our Corporate Governance Guidelines, which can be found on our website located at www.exactsciences.com under "Investor Relations—Corporate Governance."

Set forth below are the nominees to be elected at the 2018 Annual Meeting and continuing directors and, for each such continuing director, the year such director was first elected as a director, the positions currently held by each director with us, the year each director's current term will expire and the current class of each director.

CORPORATE GOVERNANCE PRINCIPLES, BOARD MATTERS AND NON-EMPLOYEE DIRECTOR COMPENSATION

Board Independence

Our Board of Directors has determined that each of Thomas D. Carey, Eli Casdin, James E. Doyle, John A. Fallon, M.D., Daniel J. Levangie, David A. Thompson, Michael S. Wyzga and Katherine S. Zanotti is an independent director within the meaning of the director independence standards of The NASDAQ Stock Market, Inc. ("NASDAQ"). Furthermore, our Board of Directors has determined that all of the members of our Audit and Finance Committee, Compensation and Management Development Committee and Corporate Governance and Nominating Committee are independent within the meaning of the director independence standards of NASDAQ and the rules of the SEC applicable to each such committee.

Executive Sessions of Independent Directors

Executive sessions of our independent directors are generally scheduled following each regularly scheduled in-person meeting of our Board of Directors. Executive sessions are led by David A. Thompson, our lead independent director, who actively solicits other independent directors for agenda items in advance of such meetings. Executive sessions of our independent directors are generally divided into two parts. The first part consists of a meeting between the independent directors and Kevin T. Conroy, our chairman and chief executive officer, and the second part consists of a meeting solely of the independent directors. The independent directors utilize the executive sessions to discuss, among other items, corporate strategy and planning, including succession planning for our executive officers.

Board Leadership Structure

Currently, Mr. Conroy serves as both the Chairman of our Board of Directors and the Chief Executive Officer of the Company. Our bylaws permit these positions to be held by the same person, and our Board of Directors believes that it is in the best interests of the Company to retain flexibility in determining whether to separate or combine the roles of Chairman and Chief Executive Officer based on our circumstances. While our Board of Directors does not have a formal policy regarding the separation of the roles of Chairman and Chief Executive Officer, our Board of Directors recognizes that one of its key responsibilities is to evaluate and determine its optimal leadership structure so as to provide independent oversight of senior management, a highly engaged Board of Directors, and the right balance between (i) effective independent oversight of the Company's business, (ii) our Board of Directors' activities and (iii) consistent corporate leadership. Our Board of Directors is open to, and assesses on at least an annual basis, different structures that provide such an optimal leadership structure, particularly given the dynamic and competitive environment in which the Company operates. As part of its most recent such assessment, the independent directors gave thorough consideration to a number of factors, including, but not limited to, the strategic goals of the Company, the dynamics of our Board of Directors, best practices within our industry, and the status of the Company's progress with respect to certain key strategic initiatives.

Based upon these considerations, the independent directors determined to maintain our Board of Directors' current leadership structure with Mr. Conroy serving as both the Chairman of our Board of Directors and the Chief Executive Officer of the Company. The independent directors based this determination on (1) Mr. Conroy's extensive experience in and knowledge of the Company, the diagnostics industry and the regulatory environment, (2) the highly effective bridge Mr. Conroy's service provides between our Board of Directors and the Company's management, (3) Mr. Conroy's continued leadership and vision necessary to lead our Board of Directors and the Company through its challenging industry and macroeconomic environments, (4) Mr. Conroy's ability to make prudent and key strategic decisions in the face of the Company's rapid growth, (5) Mr. Conroy's investor-focused perspective and (6) the effective independent leadership provided on the Board of Directors by David A. Thompson, serving in his role as lead independent director.

Our Corporate Governance and Nominating Committee Charter provides that at any time that the Company does not have an independent Chairman of our Board of Directors, the chairperson of our Corporate Governance and Nominating Committee shall also serve as our lead independent director. As such, Mr. Thompson serves as our lead independent director. The independent directors believe that Mr. Thompson has demonstrated, and will continue to demonstrate, forceful, energetic and independent leadership and thought in that position.

Our Board of Directors—which consists entirely of independent directors other than Mr. Conroy—exercises a strong, independent oversight function. This oversight function is enhanced by the fact that our Audit and Finance, Compensation and Management Development and Corporate Governance and Nominating Committees are comprised entirely of independent directors. Further, our Board of Directors meetings include regular executive sessions of the independent directors and an annual evaluation of our CEO's performance against pre-determined goals. Our Board of Directors can and will change its leadership structure if our Board of Directors determines that doing so is in the best interest of the Company and its stockholders.

Policy Governing Security Holder Communications with our Board of Directors

As set forth in our Corporate Governance Guidelines, a copy of which is available at www.exactsciences.com, security holders who wish to communicate directly with our Board of Directors, the independent directors of our Board of Directors or any individual member of our Board of Directors may do so by sending such communication by certified mail addressed to the Chairman of our Board of Directors, as a representative of the entire Board of Directors,

the Lead Independent Director, as a representative of the independent directors of our Board of Directors, or to the individual director or directors, in each case, c/o Secretary, Exact Sciences Corporation, 441 Charmany Drive, Madison, Wisconsin 53719. The Secretary reviews any such security holder communication and forwards relevant communications to the addressee.

Policies Regarding Director Nominations

Our Board of Directors has adopted a policy concerning director nominations, a copy of which is available at www.exactsciences.com. Set forth below is a summary of certain provisions of this policy.

Director Qualifications

Our Corporate Governance and Nominating Committee is responsible for identifying the appropriate qualifications, skills and characteristics desired of members of our Board of Directors in the context of the needs of the business and the current composition and needs of our Board of Directors.

Director candidates are considered based upon a variety of criteria, including demonstrated business and professional skills and experiences relevant to our business and strategic direction, concern for long-term stockholder interests, personal integrity and sound business judgment. Our Board of Directors seeks members from diverse professional backgrounds who combine a broad spectrum of relevant industry and strategic experience and expertise that, in concert, offer us and our stockholders diversity of opinion and insight in the areas most important to us and our corporate mission. In addition, nominees for director are selected to have complementary, rather than overlapping, skill sets. While our Corporate Governance and Nominating Committee does not have a formal policy concerning the diversity of our Board of Directors, our Corporate Governance and Nominating Committee considers diversity of race, ethnicity, gender, age, cultural background and professional experience in evaluating candidates for Board membership and actively seeks female and racially diverse candidates. All candidates for director nominee must have time available to devote to the activities of our Board of Directors. Our Corporate Governance and Nominating Committee also considers the independence of candidates for director nominee, including the appearance of any conflict in serving as a director. Candidates for director nominees who do not meet all of these criteria may still be considered for nomination to our Board of Directors if our Corporate Governance and Nominating Committee believes that the candidate will make an exceptional contribution to us and our stockholders.

Process for Identifying and Evaluating Director Nominees

Our Board of Directors is responsible for selecting nominees for election to our Board of Directors by our stockholders. Our Board of Directors delegates the selection process to our Corporate Governance and Nominating Committee, with the expectation that other members of our Board of Directors, and of management, may be requested to take part in the process as appropriate. Generally, our Corporate Governance and Nominating Committee identifies candidates for director nominees in consultation with management, through the use of search firms or other advisers, through the recommendations submitted by other directors or stockholders or through such other methods as our Corporate Governance and Nominating Committee deems appropriate. Once candidates have been identified, our Corporate Governance and Nominating Committee confirms that the candidates meet the qualifications for director nominees established by our Corporate Governance and Nominating Committee. Our Corporate Governance and Nominating Committee may gather information about the candidates through interviews, detailed questionnaires, comprehensive background checks, or any other means that our Corporate Governance and Nominating Committee deems to be helpful in the evaluation process. Our Corporate Governance and Nominating Committee then meets as a group to discuss and evaluate the qualities and skills of each candidate, both on an individual basis and taking into account the overall composition and needs of our Board of Directors. Based on the results of the evaluation process, our Corporate Governance and Nominating Committee recommends candidates for our Board of Directors' approval as nominees for election to our Board of Directors. Our Corporate Governance and Nominating Committee also recommends candidates for our Board of Directors' appointments to the standing committees of our Board of Directors.

Procedures for Recommendation of Director Nominees by Stockholders

The policy of our Corporate Governance and Nominating Committee is to consider properly submitted stockholder recommendations for director candidates. To submit a recommendation to our Corporate Governance and Nominating Committee for director nominee candidates, a stockholder must make such recommendation in writing and include:

»: the name and address of the stockholder making the recommendation, as they appear on our books and records, and of such record holder's beneficial owner, if any;
»: the class and number of shares of our equity that are owned beneficially and held of record by such stockholder and such beneficial owner including all "synthetic equity instruments" (e.g., derivatives, swaps, hedges, etc.), voting rights, rights to fees, dividends, or other material rights;
»: a description of the material terms of any agreements, arrangements or understandings (whether or not in writing) entered into between such stockholder or such beneficial owner and any other person for the purpose of acquiring, holding, disposing or voting of any shares of any class of our equity;
»: the name of the individual recommended for consideration as a director nominee;
»: why such recommended candidate meets our criteria and would be able to fulfill the duties of a director;
»: how the recommended candidate meets applicable independence requirements established by the SEC and NASDAQ;

CORPORATE GOVERNANCE PRINCIPLES, BOARD MATTERS AND NON-EMPLOYEE DIRECTOR COMPENSATION

»: the recommended candidate's beneficial ownership in our securities;
»: any relationships between the recommended candidate and us which may constitute a conflict of interest; and
»: all other information relating to the recommended candidate that would be required to be disclosed in solicitations of proxies for the election of directors or is otherwise required, in each case pursuant to Regulation 14A under the Exchange Act, including the recommended candidate's written consent to being named in the proxy statement as a nominee and to serving as a director if approved by our Board of Directors and elected.

Recommendations must be sent to the Chairperson of our Corporate Governance and Nominating Committee, c/o Secretary, Exact Sciences Corporation, 441 Charmany Drive, Madison, Wisconsin 53719. The Secretary must receive any such recommendation for nomination not later than the close of business on the 120th day nor earlier than the close of business on the 150th day prior to the first anniversary of the date of the proxy statement delivered to stockholders in connection with the preceding year's annual meeting of stockholders; provided, however, that with respect to a special meeting of stockholders called by us for the purpose of electing directors to our Board of Directors, the Secretary must receive any such recommendation not earlier than the 90th day prior to such special meeting nor later than the later of (1) the close of business on the 60th day prior to such special meeting or (2) the close of business on the 10th day following the day on which a public announcement is first made regarding such special meeting. We will promptly forward any such nominations to our Corporate Governance and Nominating Committee. Once our Corporate Governance and Nominating Committee receives a recommendation for a director candidate, such candidate will be evaluated in the same manner as other candidates and a recommendation with respect to such candidate will be delivered to our Board of Directors.

Policy Governing Director Attendance at Annual Meetings of Stockholders

Our policy is to schedule a regular meeting of our Board of Directors on the same date as our annual meeting of stockholders and, accordingly, directors are encouraged to be present at such stockholder meetings. All individuals serving on our Board of Directors at the time of the 2017 annual meeting attended the 2017 annual meeting of stockholders.

Code of Business Conduct and Ethics

We have in place a Code of Business Conduct and Ethics (the "Code of Ethics") that applies to all of our directors, officers and employees. The Code of Ethics is designed to deter wrongdoing and promote:

»: honest and ethical conduct, including the ethical handling of actual or apparent conflicts of interest between personal and professional relationships;
»: full, fair, accurate, timely and understandable disclosure in reports and documents that we file with, or submit to, the SEC and in other public communications that we make;
»: compliance with applicable governmental laws, rules and regulations;
»: the prompt internal reporting of violations of the Code of Ethics to an appropriate person identified in the Code of Ethics;
»: accountability for adherence to the Code of Ethics; and
»: anonymous reporting of violations of the Code of Ethics via reporting mechanisms approved by our Audit and Finance Committee.

A current copy of the Code of Ethics is available at www.exactsciences.com. A copy may also be obtained, free of charge, from us upon a request directed to Exact Sciences Corporation, 441 Charmany Drive, Madison, Wisconsin 53719, attention: Investor Relations. We intend to disclose any amendments to or waivers of a provision of the Code of Ethics by posting such information on our website available at www.exactsciences.com and/or in our public filings with the SEC.

Our Board of Directors and its Committees

Board of Directors

Our bylaws state that the number of directors constituting the entire Board of Directors shall be determined by resolution of our Board and that our Board has the authority to increase the number of directors, fill any vacancies on our Board and to decrease the number of directors to eliminate any vacancies.

Role of our Board of Directors in Risk Oversight

Our Board of Directors administers its risk oversight function directly and through our Audit and Finance Committee and our Compensation and Management Development Committee. Our Audit and Finance Committee regularly discusses with management the Company's major risk exposures, their potential financial impact on the Company, and the steps taken to monitor and control those risks and reviews with management annually a summary of risk management activities including an insurance review, a review of management's precautionary plans for disaster protection, and a review of the Company's policies and procedures with respect to cybersecurity threats and related issues. Additionally, our Audit and Finance Committee assists our Board in its oversight of the Company's compliance with legal and regulatory matters. Our Compensation and Management Development Committee, together with management, has reviewed the Company's compensation policies and practices and concluded that such policies and practices do not create risks that are reasonably likely to have a material adverse effect on the Company.

Director Compensation

Compensation Policy for Non-Employee Directors

We maintain a compensation policy for our non-employee directors (the "Director Compensation Policy") that is intended to enable us to attract and retain, on a longer-term basis, high-qualified non-employee directors. The Director Compensation Policy is supported by a periodic benchmarking exercise conducted by Radford, an Aon Consulting Company ("Radford"), the Company's independent executive compensation consultant, which positions the cash and equity compensation paid to our non-employee directors at the market median of a peer group that is reviewed annually.

Under the Director Compensation Policy, on the date of each annual stockholders meeting, each non-employee director who continues to serve as a director following such meeting is paid an annual cash retainer as follows:



BOARD MEMBER COMPENSATION	ANNUAL RETAINER ($)
Lead Independent Director		75,000
Director		50,000


COMMITTEE CHAIRPERSON COMPENSATION	ANNUAL RETAINER ($)
Audit and Finance Committee		25,000
Compensation and Management Development Committee		20,000
Corporate Governance and Nominating Committee		13,000


COMMITTEE MEMBER COMPENSATION	ANNUAL RETAINER ($)
Audit and Finance Committee		12,500
Compensation and Management Development Committee		10,000
Corporate Governance and Nominating Committee		6,500

In lieu of cash, each non-employee director may elect to receive shares of Company common stock having an equivalent dollar value.

In addition, non-employee directors are paid cash compensation of $1,500 per meeting in atypical circumstances when (1) our Board of Directors or any committee has met more than 10 times per year or (2) our Board of Directors creates a special committee.

Under the Director Compensation Policy, on the date of each annual stockholders meeting, each non-employee director who is continuing to serve as a director following such meeting is also granted restricted stock or deferred stock units having a value of $200,000 with the number of restricted stock or deferred stock units to be issued being determined based on the closing price of the Company's common stock on the grant date. These annual equity grants are scheduled to vest upon the earlier of the first anniversary of the grant date or the date of the next annual stockholders meeting; provided upon the death of a director, such director's awards vest in full; upon a director's ceasing to serve for any other reason, such director's awards vest pro rata based on the number of days since the grant date; and upon a change of control, all awards vest in full.

Under the Director Compensation Policy, if a director is elected or appointed to our Board of Directors other than on the date of the Company's annual meeting of stockholders, such director's annual cash and equity compensation as described above, for the period between the date of such election or appointment and the date of the Company's next annual meeting of stockholders, will be granted in a pro rata amount on the date of such annual meeting to reflect the date of such director's election or appointment and the date of the Company's following annual meeting of stockholders. The number of restricted stock or deferred stock units to be issued to the director based on the foregoing pro rata compensation is determined based on the closing price of the Company's common stock on the date of such director's appointment, and such restricted stock or deferred stock units is fully vested upon grant.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Other than as described below and compensation agreements and other arrangements which are described in "Compensation And Other Information Concerning Named Executive Officers" beginning on page 25, in 2017 there was not, and there is not currently proposed, any transaction or series of similar transactions to which we were or will be a party in which the amount involved exceeded or will exceed $120,000 in which any director, executive officer, holder of five percent or more of any class of our capital stock or any member of their immediate family had or will have a direct or indirect material interest.

In May 2017, the Company engaged Perspective Group LLC, an executive search firm in which Thomas Carey, a member of our Board of Directors, is majority owner, to perform certain executive searches. Under the terms of the engagement, the Company paid Perspective Group $200,000 during the year ended December 31, 2017 and expects to pay Perspective Group $200,000 during the year ended December 31, 2018.

In October 2009, our Board of Directors adopted a written policy with regard to related person transactions, which sets forth our procedures and standards for the review, approval or ratification of any transaction required to be reported in our filings with the SEC or in which one of our executive officers or directors has a direct or indirect material financial interest, with limited exceptions. Our policy is that our Audit and Finance Committee shall review the material facts of all related person transactions (as defined in the related person transaction approval policy) and either approve or disapprove of the entry into any related person transaction. In the event that obtaining the advance approval of our Audit and Finance Committee is not feasible, our Audit and Finance Committee shall consider the related person transaction and, if our Audit and Finance Committee determines it to be appropriate, may ratify the related person transaction. In determining whether to approve or ratify a related person transaction, our Audit and Finance Committee will take into account, among other factors it deems appropriate, whether the related person transaction is on terms comparable to those available from an unaffiliated third-party under the same or similar circumstances and the extent of the related person's interest in the transaction.

REPORT OF THE AUDIT AND FINANCE COMMITTEE

The Audit and Finance Committee is comprised of Eli Casdin, John A. Fallon, M.D., Daniel J. Levangie and Michael S. Wyzga. None of the members of the Audit and Finance Committee is an officer or employee of the Company, and the Board of Directors has determined that each member of the Audit and Finance Committee meets the independence requirements promulgated by The NASDAQ Stock Market and the SEC, including Rule 10A-3(b)(1) under the Exchange Act.

The Audit and Finance Committee oversees the Company's financial reporting process on behalf of the Board of Directors. Management has the primary responsibility for the financial statements and the reporting process, including the systems of internal controls and the certification of the integrity and reliability of the Company's internal controls procedures. In fulfilling its oversight responsibilities, the Audit and Finance Committee has reviewed the Company's audited consolidated balance sheets at December 31, 2017 and 2016 and the related consolidated statements of operations, comprehensive loss, stockholders' equity and cash flows for each of the three years in the period ended December 31, 2017, and has discussed them with both management and BDO USA, LLP ("BDO"), the Company's independent registered public accounting firm. The Audit and Finance Committee has also discussed with the independent registered public accounting firm the matters required to be discussed by the Auditing Standard No. 1301, Communications with Audit Committees , as adopted by the Public Company Accounting Oversight Board. The Audit and Finance Committee has reviewed permitted services under rules of the SEC as currently in effect and discussed with BDO their independence from management and the Company, including the matters in the written disclosures and the letter from the independent registered public accounting firm required by the applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant's communications with the Audit and Finance Committee concerning independence. The Audit and Finance Committee has also considered and discussed the compatibility of non-audit services provided by BDO with that firm's independence.

Based on its review of the consolidated financial statements and the aforementioned discussions, the Audit and Finance Committee concluded that it would be reasonable to recommend, and on that basis did recommend, to the Board of Directors that the audited consolidated financial statements be included in the Company's Annual Report on Form 10-K for the fiscal year ended December 31, 2017.

Respectfully submitted by the Audit and Finance Committee.

The Audit and Finance Committee:
Michael S. Wyzga, Chairperson

Compensation Discussion and Analysis

This Compensation Discussion and Analysis explains our executive compensation program as it relates to our named executive officers ("NEOs"), whose compensation information is presented in the following tables and discussion in accordance with SEC rules:


		NAME				POSITION
		Kevin T. Conroy				Chairman, President and Chief Executive Officer
		Graham P. Lidgard				Senior Vice President and Chief Science Officer
		Jeffrey T. Elliott				Chief Financial Officer
		D. Scott Coward				Senior Vice President, General Counsel and Secretary
		Maneesh K. Arora				Former Senior Vice President and Chief Operating Officer*

*: In April 2018, Mr. Arora resigned from his positions as Senior Vice President and Chief Operating Officer and a member of our Board of Directors. Mr. Arora will remain a non-executive employee of the Company for a transition period through December 31, 2018 unless such arrangement is terminated earlier.

Our executive compensation program is designed to focus executive behavior on achievement of both our annual and long-term objectives and strategy as well as align the interests of management with those of our stockholders. To that end, executive compensation consists of three primary elements: salary, long-term equity interests and an annual cash bonus opportunity based on individual and corporate performance.

Objectives of Our Executive Compensation Program

Our compensation program for our executive officers is intended to achieve the following objectives:

»: Focus executive behavior on achievement of our annual and long-term objectives and strategy;
»: Provide a competitive compensation package that enables us to attract and retain qualified executives;
»: Provide a total compensation structure that our Compensation and Management Development Committee believes is comparable to similarly-sized companies in the life sciences industry with which we may compete for talent and which consists of a mix of base salary, equity and cash incentives; and
»: Align the interests of management and stockholders by providing management with long-term incentives through equity ownership.

Elements of Executive Compensation

Our executive compensation program consists of three primary elements: salary, long-term equity interests and an annual cash bonus opportunity based on both corporate and individual performance. Pursuant to their employment agreements, certain of our executive officers participate in a long-term incentive plan that provides for certain cash payments upon certain changes of control of the Company. All of our executive officers are also eligible for certain benefits offered to employees generally, including, life, health, disability, dental and vision insurance, as well as participation in our 401(k) plan and 2010 Employee Stock Purchase Plan. We do not currently believe it is necessary for the attraction or retention of management talent to provide executive officers with compensation in the form of perquisites (other than housing and relocation benefits from time to time).

Determining Executive Compensation

It is the responsibility of our Compensation and Management Development Committee to administer our compensation practices, to ensure that they are competitive and financially prudent and that they include incentives that are designed to appropriately drive performance. To achieve this, our Compensation and Management Development Committee periodically reviews commercially-available, industry-specific compensation data for companies of generally similar employee size, stage of development and market capitalization in the diagnostic, biotechnology and medical device industries as a general guide for establishing our pay and equity practices and structures. Our Compensation and Management Development Committee, along with our Board of Directors, also reviews and approves corporate objectives used in our executive compensation program to confirm that appropriate goals have been established and tracks performance against them. On an annual basis, our Compensation and Management Development Committee reviews tally sheets reflecting each executive officer's compensation history with respect to each element of compensation, as well as projected payouts that would come due in connection with a termination or change of control.

COMPENSATION AND OTHER INFORMATION CONCERNING NAMED EXECUTIVE OFFICERS

Our Compensation and Management Development Committee conducts an annual review of performance and compensation during the first quarter of each year for the purpose of determining the compensation of executive officers other than the Chief Executive Officer. As part of this review, the Chief Executive Officer submits recommendations to our Compensation and Management Development Committee relating to the compensation of these officers. Following a review of these recommendations, our Compensation and Management Development Committee approves the compensation of these officers, with such modifications to the Chief Executive Officer's recommendations as our Compensation and Management Development Committee considers appropriate.

Our Compensation and Management Development Committee's review of the Chief Executive Officer's compensation is subject to additional procedures. With input from the independent directors, the Lead Independent Director, along with our Compensation and Management Development Committee, evaluates the Chief Executive Officer's performance and reviews the evaluation with him. Based on that evaluation and review and consultation with its independent compensation consultant, our Compensation and Management Development Committee then determines the Chief Executive Officer's compensation. The Chief Executive Officer is not permitted to attend the portions of meetings of our Compensation and Management Development Committee where the Committee votes or deliberates on his compensation.

Our Compensation and Management Development Committee has engaged Radford as its independent executive compensation consultant. Our Compensation and Management Development Committee has assessed the independence of Radford pursuant to SEC and listing exchange rules and concluded that no conflict of interest exists that would prevent Radford from serving as an independent consultant to our Compensation and Management Development Committee.

Analysis of Executive Compensation

Pursuant to its engagement, in early 2017 Radford provided our Compensation and Management Development Committee an annual review of the competitiveness of our executive compensation program, including the competitiveness of our base salaries, target total cash compensation, long-term incentives and target total direct compensation.

Radford analyzed the components of our executive compensation program against information blended from (1) proxy statement data from a peer group of companies that consisted of publicly-traded diagnostic, biotechnology and medical device companies that were similar to the Company in terms of stage of development, headcount, revenue and market capitalization and (2) survey data from a broader group of commercial stage public diagnostics, medical device and biotechnology companies with revenue between $30 million and $275 million and market capitalization between $700 million and $2.1 billion.

Our Compensation and Management Development Committee seeks to identify an executive compensation peer group of approximately 20 companies in the diagnostic, biotechnology and medical device industries at a similar stage of development and comparable financial profile that may compete with the Company for executive talent. Based on Radford's review and recommendations regarding the Company's executive compensation peer group, our Compensation and Management Development Committee approved a new peer group for 2017. In its review, Radford focused on creating a peer group that:

»: Represented companies operating in the diagnostics, medical device and biotechnology industries;
»: Contained commercialized companies with respect to the stage of such companies' development; and
»: Captured comparable companies in terms of headcount, revenue and market capitalization.

Based on Radford's recommendations, our Compensation and Management Development Committee (1) removed four companies from the prior year's peer group either because they were acquired or no longer met the targeted market capitalization level and (2) added six companies to the prior year's peer group (ABIOMED, Acorda Therapeutics, Meridian Bioscience, Myriad Genetics, Natera and Tesaro) that met the stated criteria.



26		Exact Sciences 2018 Proxy Statement

COMPENSATION AND OTHER INFORMATION CONCERNING NAMED EXECUTIVE OFFICERS

The companies in our peer group for 2017 were:


		COMPANY				INDUSTRY
		Abaxis				Health Care Equipment
		ABIOMED				Health Care Equipment
		Acorda Therapeutics				Biotechnology
		AMAG Pharmaceuticals				Biotechnology
		ARIAD Pharmaceuticals				Biotechnology
		Cardiovascular Systems				Health Care Equipment
		DepoMed				Pharmaceuticals
		DexCom				Health Care Equipment
		Foundation Medicine				Biotechnology
		Genomic Health				Biotechnology
		Halozyme Therapeutics				Biotechnology
		Heartware International				Health Care Equipment
		Insulet				Health Care Equipment
		Ionis Pharmaceuticals				Biotechnology
		Ironwood Pharmaceuticals				Biotechnology
		Meridian Bioscience				Health Care Equipment
		Myriad Genetics				Biotechnology
		Natera				Biotechnology
		Nektar Therapeutics				Pharmaceuticals
		Pacira Pharmaceuticals				Pharmaceuticals
		Quidel				Health Care Equipment
		Tesaro				Biotechnology

Based on Radford's analysis, we reached the following conclusions regarding our executive compensation program relative to our peer group:

»: Base salary levels for our NEOs would remain targeted between the 25 ^th percentile and 50 ^th percentile.
»: Total cash compensation (base salary plus annual cash bonus opportunity) levels for our NEOs would remain targeted between the 40 ^th and 50 ^th percentile.
»: The aggregate value of the long-term incentive compensation awarded to our NEOs would generally remain targeted between the 50 ^th and 75 ^th percentile.

Radford also provided us with an assessment of our annual equity award burn rate and the expected retentive value of equity awards held by our executives, as well as an analysis of the alignment of Company performance and CEO compensation.

Based on our assessment of the performance of the executives and our compensation philosophy as described in this Compensation Discussion and Analysis, in early 2017 our Compensation and Management Development Committee took the following actions:

»: Increased the base salaries of Mr. Conroy, Mr. Arora, Dr. Lidgard and Mr. Coward from $575,000 to $632,500, $453,200 to $475,900, $391,400 to $430,500 and $370,800 to $400,300, respectively, to recognize continued contributions of these individuals to the Company. Our Compensation and Management Development Committee elected not to increase Mr. Elliott's base salary for 2017 as Mr. Elliott had received an increase in base salary from $270,000 to $350,000 in November 2016 upon his appointment as Chief Financial Officer;
»: Increased Mr. Conroy's target bonus opportunity from 75% to 80% of base salary bringing Mr. Conroy's total target cash compensation to approximately the 42nd market percentile, increased Dr. Lidgard's target bonus opportunity from 40% to 50% of base salary bringing Dr. Lidgard's total target cash compensation to approximately the 50th percentile, and increased Mr. Coward's target bonus opportunity from 45% to 50% of base salary



Exact Sciences 2018 Proxy Statement		27

Table of Contents

COMPENSATION AND OTHER INFORMATION CONCERNING NAMED EXECUTIVE OFFICERS

bringing Mr. Coward's total target cash compensation to approximately the market 50th percentile. Our Compensation and Management Development Committee maintained Mr. Arora's and Mr. Elliott's target bonus opportunities at 60% and 40% of base salary, respectively; and

»: Granted annual equity awards with time-based vesting terms to Mr. Conroy, Mr. Arora, Dr. Lidgard, Mr. Elliott and Mr. Coward at the market 60th percentile (with Mr. Conroy, Mr. Arora, Dr. Lidgard and Mr. Coward each receiving additional equity awards equal to 20% of the market 60th percentile in recognition of exceptional 2017 performance), consisting of stock options covering 240,000, 132,000, 81,000, 75,000 and 65,000 shares, respectively, and RSUs covering 137,300, 75,500, 46,300, 42,900 and 37,200 shares, respectively. Mr. Coward received an additional 8,500 RSUs to compensate for a shortfall in the number of performance share units he was awarded in 2016.

2017 Bonus Plan

Our Compensation and Management Development Committee believes that a meaningful portion of our executives' compensation should be "at risk"—in other words, contingent upon successful implementation of our strategy and goals. Accordingly, one component of our executive compensation program is an annual cash bonus opportunity under which each of our executive officers is eligible to earn an annual cash bonus with a specified target amount equal to a percentage of base salary, with the actual bonus awarded to be based upon the achievement of corporate goals determined by our Compensation and Management Development Committee in its discretion. In January 2017, our Compensation and Management Development Committee approved metrics to be used to determine 2017 bonuses, which included (1) improvement of the Cologuard customer experience, (2) the growth of Cologuard revenue and profitability, (3) innovation in product development and (4) employee engagement (which was used as an additional bonus weighting only for Company management at the Vice President level and above). Our NEOs were eligible to earn bonuses for 2017 performance equal to up to 206% of their target bonuses, which were target bonuses of 80% of base salary for Mr. Conroy, 60% of base salary for Mr. Arora, 50% of base salary for each of Mr. Coward and Dr. Lidgard and 40% of base salary for Mr. Elliott. Our Compensation and Management Development Committee determined actual bonus payments after the end of 2017 based on the Committee's assessment of the performance of the Company relative to the business goals and weightings as described in the chart below.

Performance against the applicable goals is expected to be used by our Compensation and Management Development Committee in determining annual bonus payments. However, in determining actual bonus payments our Compensation and Management Development Committee ultimately relies on its judgment after a comprehensive review of Company performance, as well as consideration of qualitative and other factors, without being tied to any formulas or pre-established weightings. Our Compensation and Management Development Committee has ultimate discretion to modify the matrix and may periodically revisit goals and weightings as circumstances change (though our Compensation and Management Development Committee did not make any such modifications with respect to 2017 bonuses).

In determining 2017 bonus awards, our Compensation and Management Development Committee considered the executive team's achievement of a variety of business plan goals, as follows:

GOAL

PERFORMANCE MEASURES

WEIGHTING

Improve customer experience

•

Patient and provider satisfaction

•

Compliance rate

20%

Grow Cologuard revenue and profitability

•

Achievement of a target of online-based orders of Cologuard

•

Revenue targets

•

Increase number of ordering physicians

60%

Product innovation

•

Product study completions

•

Product research submissions

•

Development of international expansion potentials

20%

In addition, our Compensation and Management Development Committee provided each member of the executive team an opportunity to earn an additional 10% of his or her target bonus amount upon satisfactory levels of employee engagement, as measured by certain employee survey satisfaction results.

After considering the executive team's achievement of key business plan goals, which included achievement of 2017 revenue well in excess of target, our Compensation and Management Development Committee determined to award cash bonuses for 2017 performance at 182% of target. Accordingly, Mr. Conroy, Mr. Arora, Dr. Lidgard, Mr. Coward and Mr. Elliott of $920,920, $519,683, $391,755, $364,273 and $254,800, respectively.

Annual Equity Awards

We believe successful long-term Company performance is critical to enhancing stockholder value. For this reason and to conserve cash and better align the interests of management and stockholders, we emphasize long-term equity compensation, with the performance of each NEO primarily governing the Compensation and Management Development Committee's considerations in determining long-term equity awards to each of them.



28		Exact Sciences 2018 Proxy Statement

Table of Contents

COMPENSATION AND OTHER INFORMATION CONCERNING NAMED EXECUTIVE OFFICERS

In January 2017, our Compensation and Management Development Committee approved annual equity awards to our NEOs consisting of time-vesting RSUs and stock options, including the approval of the number of shares of our common stock subject to each award. Customarily, these equity awards would have been issued on February 23, 2017 in accordance with our Statement of Policy with respect to Equity Award Approvals. However, the issuance of these awards was contingent upon receipt of stockholder approval of the First Amendment to the 2010 Omnibus Long-Term Incentive Plan (As Amended and Restated Effective April 28, 2015) at the 2017 Annual Meeting of Stockholders, which increased the number of shares reserved under our Omnibus Plan (the "2017 Plan Amendment").

Pursuant to and in accordance with FASB ASC Topic 718, the grant date fair value of each equity award was calculated as of July 27, 2017, the date on which the contingency of each such equity award (stockholder approval of the 2017 Plan Amendment) was satisfied. The closing price of our common stock on July 27, 2017 was $37.93. This $37.93 closing price was significantly higher than the $21.68 closing price of our common stock on February 23, 2017, the date on which such equity awards would otherwise have been granted to our NEOs, and the date on which the FASB ASC Topic 718 grant date fair value would have been determined, had such equity awards not been subject to the contingency of stockholder approval of the 2017 Plan Amendment, which resulted in meaningfully higher grant date fair values than if such grant date fair values would have been calculated as of February 23, 2017. Please refer to Footnote 3 of the Summary Compensation Table below for additional information on the calculation of the grant date fair value of the equity awards discussed in this section.

Upon receipt of the required stockholder approval in July 2017, Mr. Conroy, Mr. Arora, Dr. Lidgard, Mr. Coward and Mr. Elliott received stock options approved in January 2017 covering 240,000, 132,000, 81,000, 75,000 and 65,000 shares, respectively. The shares underlying these options vest and become exercisable in four equal annual installments beginning on the first anniversary of the February 2017 grant date. Additionally, Mr. Conroy, Mr. Arora, Mr. Coward, Dr. Lidgard, and Mr. Elliott received RSUs covering 137,300, 75,500, 51,400, 46,300 and 37,200 shares, respectively. These RSUs vest in four equal annual installments beginning on the first anniversary of the February 2017 grant date.

These awards were intended to motivate the retention of our NEOs and provide our NEOs with a market competitive long-term equity incentive opportunity. Our Compensation and Management Development Committee believes that annual equity awards provide executive officers with the opportunity to acquire long-term stock ownership positions, which motivates them to focus on long-term stockholder value, and that time-based vesting of these awards helps us to retain our leadership team in a competitive environment.

Omnibus Plan

The Company maintains the Exact Sciences Corporation 2010 Omnibus Long-Term Incentive Plan (As Amended and Restated Effective July 27, 2017) (as amended, the "Omnibus Plan"), under which we may grant cash and equity incentive awards to eligible service providers in order to attract, motivate and retain the talent for which we compete. The plan is scheduled to terminate on July 16, 2020 unless earlier terminated by our Board of Directors. The Omnibus Plan provides for the grant of incentive stock options, nonstatutory stock options, stock appreciation rights, restricted stock awards, restricted stock units and other stock-based awards. Incentive stock options may be granted only to employees, and all other awards may be granted to our and our affiliates' employees, non-employee directors, consultants and other service providers. The Omnibus Plan is administered by our Board of Directors or a committee of our Board of Directors designated by our Board of Directors to administer the Omnibus Plan. Our Board of Directors has designated the Compensation and Management Development Committee to administer the Omnibus Plan.

Company Clawback Policy

If any of the Company's financial statements are required to be restated, the Company may recover all or a portion of any award made under the Omnibus Plan with respect to any fiscal year of the Company the financial results of which are negatively affected by the restatement. The amount to be recovered will be the amount by which the affected award exceeds the amount that would have been payable had the financial statements been initially filed as restated. Moreover, any award, amount or benefit received under the Omnibus Plan will be subject to potential cancellation, recoupment, rescission, payback or other action in accordance with the terms of any applicable Company clawback policy or any applicable law, as may be in effect from time to time, whether adopted prior to or following the date of the award.

Other Compensation

We permit executive officers to purchase common stock at a discount through our 2010 Employee Stock Purchase Plan on the same terms and conditions as our other employees. Executive officers may also participate in our 401(k) Plan, which allows for the investment of a portion of plan assets in shares of our common stock. Our Compensation and Management Development Committee approved a discretionary matching Company contribution to our 401(k) Plan for 2017. The matching contribution was made using Company stock in an amount equal to 100% of an employee's total deferrals into the plan up to a limit of 6% of the employee's total compensation (subject to IRS limits).

Role of Stockholder Say-on-Pay Votes

We provide our stockholders with the opportunity to cast an annual advisory vote on executive compensation (a "say-on-pay proposal"). At the Company's annual meeting of stockholders held in July 2017, approximately 87% of the votes cast on the say-on-pay proposal at the meeting were voted in favor of the proposal. Our Compensation and Management Development Committee believes this vote affirms our stockholders' support of the Company's approach to executive compensation and did not make specific changes to our executive compensation program in response to the vote. However, our Compensation and Management Development Committee continues to review and refine the design and administration of our executive pay practices. Our Compensation and Management Development Committee also will continue to consider the outcome of the Company's say-on-pay votes when making future compensation decisions for our NEOs.

Stock Ownership Guidelines

We maintain Stock Ownership Guidelines to encourage ownership of shares of the Company's common stock by our directors and senior executives, to further align their interests with the long-term interests of our stockholders and to further promote the Company's commitment to sound corporate governance. Under these guidelines, directors and senior executives have until the later of (1) April 21, 2019 and (2) three years from the date the director or senior executive becomes subject to the guidelines, to achieve an ownership target determined as follows:

POSITION

OWNERSHIP TARGETS: LOWER OF:

Base Salary Multiple

Fixed Share Target

Board of Directors

Number of shares with a stock value equal to or greater than 3 times annual retainer

Number of shares equal to or greater than annual retainer, divided by stock value, multiplied by 3

CEO

Number of shares with a stock value equal to or greater than 6 times base salary

Number of shares equal to or greater than base salary, divided by stock value, multiplied by 6

Senior Executive Officers

Number of shares with a stock value equal to or greater than 2 times base salary

Number of shares equal to or greater than base salary, divided by stock value, multiplied by 2

Under the Base Salary Multiple, "stock value" is calculated annually at the end of each fiscal year based on the average of the closing prices of our common stock for the last 30 trading days of the fiscal year.

Under the Fixed Share Target, "stock value" is calculated as of the later of (1) January 1, 2012, and (2) the date the director or senior executive originally becomes subject to the Stock Ownership Guidelines, as the case may be, based on the average of the closing prices of our common stock for the 30 days leading up to, and inclusive of, the applicable date.

Under both the Base Salary Multiple and Fixed Share Target, "annual retainer" or "base salary" is the director's annual retainer or the executive's base salary, as applicable, at the end of each fiscal year (at which time each director's and senior executive's compliance will be assessed).

Each director and senior executive is expected to continuously own sufficient shares to satisfy either the Base Salary Multiple or the Fixed Share Target ownership target once attained for as long as he or she remains subject to the Stock Ownership Guidelines. If an individual's ownership target increases because of a change in position or compensation, the individual will have a three-year period to achieve the incremental amount of shares beginning on the effective date of the change in position or compensation.

Following the initial three-year period that the director or senior executive is afforded to achieve his or her individual ownership target under the Stock Ownership Guidelines, until a director or senior executive has satisfied the applicable ownership target, the director or senior executive is required to retain an amount equal to 50% of the net shares received as the result of the exercise, vesting or payment of any Company equity awards granted to the director or executive. This amount is calculated using the closing price of our common stock on the trading day immediately preceding the date of exercise, vesting or payment of the equity award. Once a director or senior executive achieves his or her individual ownership target, the retention requirements as described above no longer will apply to such director or senior executive unless a disposition by such director or senior executive would cause such individual's stock ownership to fall below his or her ownership target.

Restrictions on Hedging and Pledging of Company Securities

Our Insider Trading Policy prohibits short sales of our securities, including a "sale against the box," by our directors and executives. Our Insider Trading Policy also prohibits directors and employees from engaging in hedging or monetization transactions, such as zero-cost collars and forward sale contracts, as they involve the establishment of a short position in our securities. Our Insider Trading Policy also prohibits directors and executives from holding our securities in a margin account or pledging such securities as collateral for a loan.

Employment Agreements with NEOs

In April 2009, Kevin T. Conroy and Maneesh K. Arora joined us as our President & Chief Executive Officer and Senior Vice President & Chief Financial Officer, respectively. In November 2016, Jeffrey T. Elliott became our Chief Financial Officer. In August 2009, Graham P. Lidgard joined us as our Senior Vice President & Chief Science Officer. In January 2015, D. Scott Coward joined us as Senior Vice President, General Counsel & Secretary. In February 2012, Mr. Arora was promoted to Chief Operating Officer in addition to his title of Chief Financial Officer. In August 2013, Mr. Arora dropped the title of Chief Financial Officer upon the Company's appointment of a new Senior Vice President, Finance. In April 2018, Mr. Arora resigned as our Senior Vice

President and Chief Operating Officer. In connection with each of these appointments we have entered into an employment agreement under which we have agreed to certain compensation arrangements and severance and change of control benefits. At this time, our Board of Directors does not intend to provide any additional tax gross-up payments to employees it may hire in the future.

Each of these packages was determined based on negotiations with the applicable NEO and taking into account his background and qualifications and the nature of his position. We believe that these compensation packages are appropriate in light of the competition for top executives in the biotechnology field and among similarly-situated companies, and that the terms of these arrangements are consistent with our executive compensation goals, including the balancing of short-term and long-term compensation to properly motivate our NEOs.

Conroy Employment Agreement

Mr. Conroy's employment agreement, dated March 18, 2009, provides for a minimum base salary and for a minimum target bonus opportunity equal to at least 50% of his base salary, with the exact amount of any such bonus to be based upon the achievement of corporate and individual performance goals to be determined by our Compensation and Management Development Committee. For 2017, Mr. Conroy's base salary was $632,500 and his target bonus opportunity was 80% of his base salary. Pursuant to his employment agreement, Mr. Conroy was also granted an option to purchase 2.5 million shares of our common stock at an exercise price of $0.83 (the closing price of our common stock on the date Mr. Conroy was hired).

Under his agreement, Mr. Conroy would be entitled to certain payments and benefits in connection with certain termination events or a change of control as described under " Potential Benefits upon Termination or Change of Control " beginning on page 32 below. The agreement also prohibits Mr. Conroy from engaging in certain activities involving competition with us and from soliciting our employees for an 18-month period following termination of his employment with the Company.

Lidgard Employment Agreement

Dr. Lidgard's employment agreement, dated August 1, 2009, provides for a minimum base salary and for a minimum target bonus opportunity equal to at least 40% of his base salary, with the exact amount of any such bonus to be based upon the achievement of corporate and individual performance goals to be determined by our Compensation and Management Development Committee. For 2017, Dr. Lidgard's base salary was $430,500 and his target bonus opportunity was 50% of his base salary. Pursuant to his employment agreement, Dr. Lidgard was also granted an option to purchase 600,000 shares of our common stock, at an exercise price of $2.88 (the closing price of our common stock on the date Dr. Lidgard was hired).

Under his agreement, Dr. Lidgard would be entitled to certain payments and benefits in connection with certain termination events or a change of control as described under " Potential Benefits upon Termination or Change of Control " beginning on page 32 below.

Arora Employment Agreement

Mr. Arora's employment agreement, dated March 18, 2009, was terminated on April 25, 2018, when Mr. Arora resigned as our Senior Vice President and Chief Operating Officer and transitioned to a non-executive employee position. Mr. Arora's employment agreement provided for a minimum base salary and for a minimum target bonus opportunity equal to at least 40% of his base salary, with the exact amount of any such bonus to be based upon the achievement of corporate and individual performance goals to be determined by our Compensation and Management Development Committee. For 2017, Mr. Arora's base salary was $475,900 and his target bonus opportunity was 60% of his base salary. Pursuant to his employment agreement, Mr. Arora was also granted an option to purchase 1.25 million shares of our common stock, at an exercise price of $0.83 (the closing price of our common stock on the date Mr. Arora was hired).

Under his agreement, Mr. Arora was entitled to certain payments and benefits in connection with certain termination events or a change of control as described under " Potential Benefits upon Termination or Change of Control " below. The agreement also prohibited, and the Arora Transition Agreement (defined below) prohibits, Mr. Arora from engaging in certain activities involving competition with us and from soliciting our employees for an 18-month period following termination of his employment with the Company.

In connection with Mr. Arora's resignation as Senior Vice President and Chief Operating Officer and his transition into a non-executive employee role, on April 25, 2018, we entered into an Employee Transition Agreement with Mr. Arora (the "Arora Transition Agreement") pursuant to which Mr. Arora will remain a non-executive employee of the Company for a transition period through December 31, 2018 (the "Transition Period"). The Arora Transition Agreement terminated our employment agreement with Mr. Arora. Pursuant to the Arora Transition Agreement, Mr. Arora will continue to receive during the Transition Period the same compensation he was receiving prior to his change in roles, in exchange for a release of claims and his continued compliance with all restrictive covenants.

Change of Control and Severance

We believe that providing executives with severance and change of control protection is important for the following reasons:

»: to allow executives to value the forward looking elements of their compensation packages, and therefore limit retention risk; and
»: to provide compensation assurances which are competitive with those of other similarly-situated companies.

Accordingly, the Company's employment agreements and equity awards generally provide for salary continuation in the event of certain employment terminations beyond the control of the executive, as well as varying degrees of accelerated vesting of equity awards in the event of a change of control of the Company.

For further information see "Potential Benefits upon Termination or Change of Control" below.

Potential Benefits upon Termination or Change of Control

This "Potential Benefits upon Termination or Change of Control" section should be read in conjunction with the "Potential Payments upon Termination or Change of Control" section below, which provides a table that quantifies the benefits described in this section.

Severance and Change of Control Arrangements in General

We have entered into employment agreements and maintain certain plans that will require us to provide compensation and other benefits to our executive officers in connection with certain events related to a termination of employment or change of control. In connection with Mr. Arora's resignation as Senior Vice President and Chief Operating Officer and his transition into a non-executive employee role, on April 25, 2018, we entered into the Arora Transition Agreement, pursuant to which Mr. Arora will remain a non-executive employee of the Company for the Transition Period. The Arora Transition Agreement terminated our employment agreement with Mr. Arora, certain terms of which are summarized below. Pursuant to the Arora Transition Agreement, Mr. Arora will continue to receive during the Transition Period the same compensation he was receiving prior to his change in roles, in exchange for a release of claims and his continued compliance with all restrictive covenants.

Conroy Employment Agreement

Under his employment agreement, Mr. Conroy would, upon termination without "cause," resignation for "good reason" or certain "change of control" events (in each case as defined in Mr. Conroy's agreement), be entitled to receive certain benefits, as described below.

Under Mr. Conroy's employment agreement, upon termination without cause or resignation for good reason, Mr. Conroy would become entitled to receive the following:

»: In the event Mr. Conroy's employment is terminated by the Company without cause or by Mr. Conroy for good reason in anticipation or contemplation of a pending or potential change of control or while a potential change of control is under consideration or being negotiated by the Company's Board of Directors, Mr. Conroy will be deemed to remain an employee for purposes of the incentive plan to which he is entitled to participate under his employment agreement (the "Long Term Incentive Plan") as of the effective date of the change of control and will receive a full payout under the Long Term Incentive Plan as described in his employment agreement as though he remained an employee of the Company as of the effective date of such change of control; and
»: A tax gross-up payment in an amount sufficient to cause the net amount retained by him, after deduction of any parachute payment excise taxes, to equal the amounts payable as described above. At this time, our Board of Directors does not intend to provide any additional tax gross-up payments to employees it may hire in the future.

Change in Control Benefits under Omnibus Plan

Except as otherwise specifically provided in the applicable award agreement or in an executive's employment agreement, upon the consummation of a change in control (as defined in the Omnibus Plan): all outstanding awards will remain the obligation of the Company or be assumed by the surviving or acquiring entity, and there will be automatically substituted for the shares of our common stock then subject to the awards the consideration payable with respect of the outstanding shares of our common stock in connection with the change in control and all outstanding awards will vest as if the vesting start date with respect to the award was one year prior to the vesting start date set forth in the award agreement relating to the award. In addition to the foregoing, with respect to awards granted prior to the consummation of the change in control, in the event that any grantee who remains an employee of the Company or the acquiring or surviving entity immediately following the consummation of the change in control is terminated without cause (as defined in the Omnibus Plan) or terminates his or her own employment for good reason (as defined in the Omnibus Plan) prior to the first anniversary of the consummation of the change in control: (1) all options outstanding on the date the grantee's employment is terminated, will become immediately exercisable in full and will terminate, to the extent unexercised, on their scheduled expiration date, and if the shares of our common stock subject to the options are subject to repurchase provisions then the repurchase restrictions will immediately lapse; (2) all restricted stock awards outstanding on the date the grantee's employment is terminated, will become free of all repurchase provisions; and (3) all other stock-based awards will become exercisable, realizable or vested in full, or will be free of all repurchase provisions, as the case may be.

The summary of the foregoing benefits arising out of a change in control under the Omnibus Plan are subject to and qualified by the terms and conditions of all applicable award agreements and employment agreements to which our named executive officers are a party, in each case, as described in this Proxy Statement.

(1)		The amounts shown in this column indicate the grant date fair value of stock awards computed in accordance with FASB ASC Topic 718. Generally, the grant date fair value is the amount that we would expense in our financial statements over the award's vesting schedule. For additional information regarding the assumptions made in calculating these amounts, see the Notes to our audited, consolidated financial statements included in our Annual Report on Form 10-K for 2017. These amounts reflect our accounting expense for these awards and do not correspond to the actual value that may be recognized by our NEOs.
(2)		The amounts shown in this column indicate the grant date fair value of option awards computed in accordance with FASB ASC Topic 718. Generally, the grant date fair value is the amount that we would expense in our financial statements over the award's vesting schedule. For additional information regarding the assumptions made in calculating these amounts, see the Notes to our audited, consolidated financial statements included in our Annual Report on Form 10-K for 2017. These amounts reflect our accounting expense for these awards and do not correspond to the actual value that may be recognized by our NEOs.
(3)		The amounts reported in the Stock Awards and Option Awards columns for 2017 represent the grant date fair value of time-based option and RSU awards that were approved by our Compensation and Management Development Committee on January 31, 2017 and made effective (for Omnibus Plan purposes) on February 23, 2017 in accordance with our Statement of Policy with respect to Equity Award Approval (the "2017 Equity Awards"). The issuance of each 2017 Equity Award was subject to and contingent upon approval by our stockholders at the 2017 annual meeting of the First Amendment to the 2010 Omnibus Long-Term Incentive Plan (As Amended and Restated Effective April 28, 2015) (the "2017 Plan Amendment"), which approval was obtained on July 27, 2017.
		Pursuant to and in accordance with FASB ASC Topic 718, the grant date fair value of each 2017 Equity Award is calculated as of July 27, 2017, the date on which the contingency of each such 2017 Equity Award was satisfied (which, in the case of the time-based option awards included in the 2017 Equity Awards, is based on a Black-Scholes valuation model based on the fair market value of our common stock on July 27, 2017). The closing price of our common stock on July 27, 2017 was $37.93.
		The $37.93 closing price of our common stock on July 27, 2017 (the FASB ASC Topic 718 grant date) was significantly higher than the $21.68 closing price of our common stock on February 23, 2017, the date on which, pursuant to our Statement of Policy with respect to Equity Award Approvals, the 2017 Equity Awards would otherwise have been granted to our NEOs, and the date on which the FASB ASC Topic 718 grant date fair value would have been determined, had the 2017 Equity Awards not been subject to the contingency of stockholder approval of the 2017 Plan Amendment. Thus, as a result of applicable SEC and accounting rules—and the significant increase in the price of our common stock from February 2017 to July 2017—the values reflected in the Summary Compensation Table for the 2017 Equity Awards are meaningfully higher than the values when the Compensation and Management Development Committee approved the awards.
		For illustrative purposes only, below is a table setting forth, with respect to each NEO, (i) the grant date fair value of each 2017 Equity Award as reflected in the Summary Compensation Table, (ii) the grant date fair value of each 2017 Equity Award on February 23, 2017, calculated under FASB ASC Topic 718, had such 2017 Equity Award not been subject to the contingency of stockholder approval of the 2017 Plan Amendment, (iii) the differences between such grant date fair values and (iv) each NEO's total compensation for 2017 had the grant date fair values of such NEO's 2017 Equity Awards been calculated as of February 23, 2017.

(1): The equity awards set forth in this table were approved by our Compensation and Management Development Committee on January 31, 2017 and made effective (for Omnibus Plan purposes) on February 23, 2017. However, the issuance of each equity award was subject to and contingent upon approval by our stockholders at the 2017 annual meeting of the 2017 Plan Amendment. As a result, each such award was not granted, for accounting or SEC reporting purposes, until such contingency was satisfied on July 27, 2017. Please refer to Footnote 3 of the Summary Compensation Table above for additional information on the calculation of the grant date fair value of the equity awards set forth in this table.
(2): The amounts shown in this column indicate the grant date fair value of option awards and the grant date fair value of RSUs computed in accordance with FASB ASC Topic 718. Generally, the grant date fair value is the amount that we would expense in our financial statements over the award's vesting schedule. For additional information regarding the assumptions made in calculating these amounts, see the Notes to our audited, consolidated financial statements included in our Annual Report on Form 10-K for 2017. These amounts reflect our accounting expense for these awards and do not correspond to the actual value that will be recognized by our NEOs.
(3): The shares underlying this option vest and become exercisable in four equal annual installments beginning on February 23, 2018.
(4): Represents RSUs which vests in four equal annual installments beginning on February 23, 2018.

CEO PAY RATIO

As required by SEC rules, we are providing the following information about the relationship of the annual total compensation for 2017 of our employees and our CEO Mr. Conroy. The pay ratio provided below is a reasonable estimate calculated in accordance with SEC rules and methods for disclosure.

For 2017, the median of the annual total compensation of all our employees (other than our CEO) was $98,724; and the annual total compensation of our CEO, for purposes of this pay ratio disclosure (as discussed below), was $13,278,504. As a result, the ratio of the annual total compensation of our CEO to the median of the annual total compensation of all our employees was approximately 135 to 1. We took the following steps to identify the median of the annual total compensation of all our employees, as well as to determine the annual total compensation of our median employee and our CEO.

We identified our median employee by (A) aggregating for each of our employees (other than our CEO) as of December 13, 2017 (our median employee determination date): (1) for permanent salaried employees, annual base salary, and solely for hourly employees, hourly rate multiplied by expected annual work schedule, including overtime (adjusted for the portion of the year worked for non-permanent employees), (2) target bonus for 2017, and (3) estimated grant date fair value of equity awards granted during 2017, and (B) ranking our employees from lowest to highest using this compensation measure.

For the annual total compensation of our median employee, we identified and calculated the elements of that employee's compensation for 2017 in accordance with the requirements of Item 402(c)(2)(x), and then added the Company's annual share of the cost of medical, dental, disability, and life insurance for the employee, resulting in annual total compensation of $98,724. For the annual total compensation of our CEO, we used the amount reported in the "Total" column of our 2017 Summary Compensation Table, adjusted as follows: to maintain consistency between the annual total compensation of our CEO and our median employee, we added the Company's annual share of the cost of medical, dental, disability, and life insurance for our CEO (estimated at $13,415) to the amount reported in the Summary Compensation Table. This resulted in annual total compensation for purposes of determining the CEO pay ratio of $13,278,504, which exceeded the amount reported for our CEO in the Summary Compensation Table by $13,415.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Exchange Act requires our directors, executive officers and persons who own more than ten percent of a registered class of our equity securities to file reports of ownership and changes in ownership with the SEC. Such persons are required by SEC regulations to furnish us with copies of all such filings. Based solely on our review of copies of such filings, we believe that all reporting persons complied on a timely basis with all Section 16(a) filing requirements during the year ended December 31, 2017, except that Scott Coward filed one late Form 4 with respect to the vesting of restricted stock units.

Our Board of Directors knows of no business that will be presented for consideration at the 2018 Annual Meeting other than those items stated above. If any other business should come before the 2018 Annual Meeting, votes may be cast pursuant to proxies in respect to any such business in the best judgment of the person or persons acting under the proxies.

QUESTIONS AND ANSWERS

Why am I receiving these materials?

You have received these proxy materials because our Board of Directors is soliciting your proxy to vote your shares at the annual meeting. The proxy statement includes information that we are required to provide you under Securities and Exchange Commission ("SEC") rules and is designed to assist you in voting your shares.

What is a proxy?

Our Board of Directors is asking for your proxy. This means you authorize persons selected by us to vote your shares at the annual meeting in the way that you instruct. All shares represented by valid proxies received before the annual meeting will be voted in accordance with the stockholder's specific voting instructions.

What is included in these materials?

These materials include:

•: the proxy statement for the annual meeting;
•: a proxy card for the annual meeting; and
•: the 2018 Annual Report to Stockholders, which includes our Annual Report on Form 10-K for the year ended December 31, 2017.

What items will be voted on at the Annual Meeting?

There are three proposals scheduled to be voted on at the annual meeting:

•: the election of the nominees to our Board of Directors nominated by our Board of Directors as Class III directors to serve until the 2021 annual meeting of stockholders;
•: the ratification of our Audit and Finance Committee's appointment of BDO USA, LLP ("BDO") as our independent registered public accounting firm for the fiscal year ending December 31, 2018; and
•: the advisory vote on the compensation paid to our named executive officers.

Our Board of Directors is not aware of any other matters to be brought before the meeting. If other matters are properly raised at the meeting, the proxy holders may vote any shares represented by proxy in their discretion.

What are our Board of Directors' voting recommendations?

Our Board of Directors recommends that you vote your shares:

•: FOR the nominees to our Board of Directors as Class III directors to serve until the 2021 annual meeting of stockholders;
•: FOR the ratification of our Audit and Finance Committee's appointment of BDO as our independent registered public accounting firm for 2018; and
•: FOR the approval of the advisory vote regarding the compensation paid to our executive officers.

Who can attend the annual meeting?

Admission to the annual meeting is limited to:

•: stockholders as of the close of business on May 31, 2018;
•: holders of valid proxies for the annual meeting; and
•: our invited guests.

Each stockholder may be asked to present valid picture identification such as a driver's license or passport and proof of stock ownership as of the record date.

Our Board of Directors set May 31, 2018 as the record date. All record holders of Exact common stock as of the close of business on that date are entitled to vote. Each share of common stock is entitled to one vote. As of the record date, there were 122,290,448 shares of common stock outstanding.

QUESTIONS AND ANSWERS

What is a stockholder of record?

A stockholder of record or registered stockholder is a stockholder whose ownership of Exact stock is reflected directly on the books and records of our transfer agent, American Stock Transfer and Trust Company, LLC. If you hold stock through an account with a bank, broker or similar organization, you are considered the beneficial owner of shares held in "street name" and are not a stockholder of record. For shares held in street name, the stockholder of record is your bank, broker or similar organization. We only have access to ownership records for the registered shares. If you are not a stockholder of record, we will require additional documentation to evidence your stock ownership as of the record date, such as a copy of your brokerage account statement, a letter from your broker, bank or other nominee or a copy of your notice or voting instruction card. As described below, if you are not a stockholder of record, you will not be able to vote your shares unless you have a proxy from the stockholder of record authorizing you to vote your shares.

How do I vote?

You may vote by any of the following methods:

•: In person. Stockholders of record and beneficial stockholders with shares held in street name may vote in person at the meeting. If you hold shares in street name, you must also obtain a proxy from the stockholder of record authorizing you to vote your shares.
•: By mail, Internet or telephone. Stockholders of record may vote by (i) signing and returning the proxy card provided; (ii) accessing the website 'www.voteproxy.com' and following the on-screen instructions or (iii) calling 1-800-776-9437 with the control number included on your proxy card.
•: Beneficial owners of shares held in "street name." You may vote by following the voting instructions provided to you by your bank or broker.

How can I change or revoke my vote?

You may change or revoke your vote as follows:

•: Stockholders of record. You may change or revoke your vote by submitting a written notice of revocation to Exact Sciences Corporation c/o Secretary at 441 Charmany Drive, Madison, Wisconsin 53719 or by submitting another vote on or before July 25, 2018.
•: Beneficial owners of shares held in "street name." You may change or revoke your voting instructions by following the specific directions provided to you by your bank or broker.

What happens if I do not give specific voting instructions?

Stockholders of record. If you are a stockholder of record and you sign and return a proxy card without giving specific voting instructions then the proxy holders will vote your shares in the manner recommended by our Board of Directors on all matters presented in this proxy statement and as the proxy holders may determine in their discretion for any other matters properly presented for a vote at the meeting.

Beneficial owners of shares held in "street name." If you are a beneficial owner of shares held in street name and do not provide the organization that holds your shares with specific voting instructions, the organization that holds your shares may generally vote on routine matters but cannot vote on non-routine matters. If the organization that holds your shares does not receive instructions from you on how to vote your shares on a non-routine matter, the organization that holds your shares will inform the inspector of election that it does not have the authority to vote on this matter with respect to your shares. This is referred to as a "broker non-vote."

What ballot measures are considered "routine" or "non-routine?"

The election of directors ("Proposal 1") and the advisory vote on the compensation paid to our executive officers ("Proposal 3") are considered to be non-routine matters under applicable rules. A broker or other nominee cannot vote without instructions on non-routine matters, and therefore there may be broker non-votes on Proposals 1 and 3.

The ratification of the appointment of BDO as our independent registered public accounting firm for 2018 ("Proposal 2") is considered to be a routine matter under applicable rules. A broker or other nominee may generally vote on routine matters, and we do not expect there to be any broker non-votes with respect to Proposal 2.

What is the quorum for the annual meeting?

The presence, in person or by proxy, of the holders of a majority of the shares entitled to vote is necessary for the transaction of business at the annual meeting. This is called a quorum.

What is the voting requirement to approve each of the proposals?

The following are the voting requirements for each proposal:

•: Proposal 1, Election of Directors. The nominees receiving the highest number of votes will be elected as Class III directors to serve until the 2021 annual meeting of stockholders. Under the majority voting policy contained in our Corporate Governance Guidelines, any nominee for director in an

QUESTIONS AND ANSWERS

uncontested election who receives a greater number of votes "withheld" from his or her election than votes "for" such election must offer his or her resignation as a director to our Corporate Governance & Nominating Committee of our Board of Directors. Upon receipt of this offer of resignation, our Corporate Governance & Nominating Committee will consider the offer of resignation and recommend to our Board of Directors action to be taken with respect to the offer of resignation, including whether or not to accept such offer of resignation. Our Board of Directors will then act upon such recommendation and promptly disclose its decision, together with an explanation of the reasons behind such decision.

•: Proposal 2, Ratification of Appointment of Independent Registered Public Accounting Firm. The ratification of our Audit and Finance Committee's appointment of BDO as our independent registered public accounting firm for 2018 will be approved if a majority of stockholders present or represented, in person or by proxy, and voting on this matter are cast in favor of the proposal.
•: Proposal 3, Advisory Vote on Executive Compensation. The compensation paid to our named executive officers will be considered approved if a majority of the votes of stockholders present or represented, in person or by proxy, and voting on this matter, are cast in favor of the proposal.

How are abstentions and broker non-votes treated?

Broker non-votes and abstentions are counted for purposes of determining whether a quorum is present. Broker non-votes and abstentions are not counted as votes cast on any proposal considered at the annual meeting and, therefore, will have no effect on the proposals regarding the election of directors and the advisory vote on the compensation of our named executive officers. We expect no broker non-votes on the appointment of BDO as our independent registered public accounting firm for 2018. Abstentions will have no effect on the proposal ratifying the appointment of BDO as our independent registered public accounting firm for 2018.

Who pays for solicitation of proxies?

We are paying the cost of soliciting proxies. We will reimburse brokerage firms and other custodians, nominees and fiduciaries for their reasonable out-of-pocket expenses for sending proxy materials to stockholders and obtaining their votes. In addition to soliciting the proxies by mail, certain of our directors, officers and regular employees, without compensation, may solicit proxies personally or by telephone, facsimile and email.

Where can I find the voting results of the annual meeting?

We will announce preliminary or final voting results at the annual meeting and publish final results in a Form 8-K filed with the SEC within four business days following the meeting.

What is the deadline to propose actions for consideration or to nominate individuals to serve as directors at the 2019 annual meeting of stockholders?

Requirements for Stockholder Proposals to Be Considered for Inclusion in the Company's Proxy Materials. Stockholder proposals to be considered for inclusion in the proxy statement and form of proxy relating to the 2019 annual meeting of stockholders must be received no later than February 29, 2019. In addition, all proposals will need to comply with Rule 14a-8 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), which lists the requirements for the inclusion of stockholder proposals in company-sponsored proxy materials. Stockholder proposals must be delivered to the Company's Secretary at 441 Charmany Drive, Madison, Wisconsin 53719.

Requirements for Stockholder Nominations or Proposals to Be Brought Before the 2019 Annual Meeting of Stockholders. Notice of any director nomination or other proposal that you intend to present at the 2019 annual meeting of stockholders, but do not intend to have included in the proxy statement and form of proxy relating to the 2019 annual meeting of stockholders, must be delivered to the Company's Secretary at 441 Charmany Drive, Madison, Wisconsin 53719 not earlier than the close of business on March 28, 2019 and not later than the close of business on April 27, 2019.
