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.  Stockholders of record may vote by signing and returning the proxy card provided.



•

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 24, 2013.



•

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 the 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

3

Table of Contents

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."

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

        The election of directors ("Proposal 1"), the advisory vote on the compensation paid to our executive officers ("Proposal 2"), and the approval of the amendment to the 2010 Omnibus Long-Term Incentive Plan ("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, 2 and 3.

        The ratification of the appointment of BDO as our independent registered public accounting firm for 2013 ("Proposal 4") 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 4.

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 three nominees receiving the highest number of votes will be elected as Class I directors to serve until the 2016 annual meeting of stockholders.



•

Proposal 2, Advisory Vote on Executive Compensation.  The compensation paid to our 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.



•

Proposal 3, Amendment to the 2010 Omnibus Long-Term Incentive Plan.  Approval of the amendment to the 2010 Omnibus Long-Term Incentive Plan to increase the number of shares reserved for issuance thereunder by 2,800,000 shares and increase the fungible share ratio to 1.55 (from 1.35) and re-approval of individual award limits and performance goals for purposes of Section 162(m) of the Internal Revenue Code of 1986, as amended, will be considered obtained 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.



•

Proposal 4, Ratification of Appointment of Independent Registered Public Accounting Firm.  The ratification of the Audit Committee's appointment of BDO as our independent registered public accounting firm for 2013 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.

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

4

directors, the advisory vote on the compensation of our executive officers and the amendment to the 2010 Omnibus Long-Term Incentive Plan. We expect no broker non-votes on the proposal regarding the ratification of the appointment of BDO as our independent registered public accounting firm for 2013, and abstentions will have no effect on this proposal.

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 2014 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 2014 annual meeting of stockholders must be received no later than February 27, 2014. 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 Proposals to Be Brought Before the 2014 Annual Meeting of Stockholders.    Notice of any director nomination or other proposal that you intend to present at the 2014 annual meeting of stockholders, but do not intend to have included in the proxy statement and form of proxy relating to the 2014 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 27, 2014 and not later than the close of business on April 26, 2014.

Board Independence

        The Board of Directors has determined that each of Thomas D. Carey, James P. Connelly, Sally W. Crawford, Daniel J. Levangie, Katherine S. Napier, Lionel N. Sterling and David A. Thompson is an independent director within the meaning of the director independence standards of The NASDAQ Stock Market, Inc. ("NASDAQ"). Furthermore, the Board has determined that all of the members of the Audit Committee, Compensation 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 the Board of Directors. Executive sessions do not include any non-independent directors and are led by the chairman of the Board of Directors, who is independent.

Board Leadership Structure

        The Board of Directors has an independent chairman, meaning that the positions of chairman of the Board of Directors and Chief Executive Officer are not held by a single individual. The Board of Directors believes that having an independent chairman is beneficial in that it ensures that management is subject to independent and objective oversight and the independent directors have an active voice in the governance of the Company.

Policy Governing Security Holder Communications with the 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 the Board, the independent directors of the Board or any individual member of the Board may do so by sending such communication by certified mail addressed to the Chairman of the Board, as a representative of the entire Board of Directors or the independent directors of the Board, 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

        The 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

        The Corporate Governance and Nominating Committee is responsible for identifying the appropriate qualifications, skills and characteristics desired of members of the Board of Directors in the context of the needs of the business and the current composition and needs of the 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. The 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. However, the Corporate Governance and Nominating Committee does not have a formal policy concerning the diversity of the Board of Directors. All candidates for director nominee must have time available to devote to the activities of the Board of Directors. The 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 the Board of Directors, if the 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

        The Board of Directors is responsible for selecting nominees for election to the Board of Directors by the stockholders. The Board of Directors delegates the selection process to the Corporate Governance and Nominating Committee, with the expectation that other members of the Board of Directors, and of management, may be requested to take part in the process as appropriate. Generally, the 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 the Corporate Governance and Nominating Committee deems appropriate. Once candidates have been identified, the Corporate Governance and Nominating Committee confirms that the candidates meet the qualifications for director nominees established by the Corporate Governance and Nominating Committee. The Corporate Governance and Nominating Committee may gather information about the candidates through interviews, detailed questionnaires, comprehensive background checks, or any other means that the Corporate Governance and Nominating Committee deems to be helpful in the evaluation process. The 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 the Board of Directors. Based on the results of the evaluation process, the Corporate Governance and Nominating Committee recommends candidates for the Board of Directors' approval as director nominees for election to the Board of Directors. The Corporate Governance and Nominating Committee also recommends candidates for the Board of Directors' appointment to the standing committees of the Board of Directors.

Procedures for Recommendation of Director Nominees by Stockholders

        The policy of the Corporate Governance and Nominating Committee is to consider properly submitted stockholder recommendations for director candidates. To submit a recommendation to the 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;



•

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 the Board of Directors and elected.

        Recommendations must be sent to the Chairman of the 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 the 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 the Corporate Governance and Nominating Committee. Once the 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 the Board of Directors.

Policy Governing Director Attendance at Annual Meetings of Stockholders

        Our policy is to schedule a regular meeting of the 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 of our board members attended the 2012 annual meeting of stockholders, except Mr. Levangie.

Code of Business Conduct 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 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.

Role of the Board of Directors in Risk Oversight

        The Board of Directors administers its risk oversight function directly and through the Audit Committee, the Compensation Committee and the Innovation and Technology Committee. The Audit 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 and management's precautionary plans for disaster protection. Additionally, the Audit Committee assists the Board in its oversight of the Company's compliance with legal and regulatory matters. The Compensation 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. The Innovation and Technology Committee regularly consults with the Board of Directors concerning the risks related to the management and commercialization of the Company's product technologies.

REPORT OF THE AUDIT COMMITTEE

        The Audit Committee is comprised of Sally W. Crawford, Katherine S. Napier and Lionel N. Sterling. None of the members of the Audit Committee is an officer or employee of the Company, and the Board of Directors has determined that each member of the Audit 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 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 Committee has reviewed the Company's audited balance sheets at December 31, 2012 and 2011 and the related statements of operations, comprehensive loss, stockholders' equity and cash flows for each of the three years in the period ended December 31, 2012, and has discussed them with both management and BDO USA, LLP ("BDO"), the Company's independent registered public accounting firm. The Audit Committee has also discussed with the independent registered public accounting firm the matters required to be discussed by the Statement on Auditing Standards No. 61, as amended (AICPA, Professional Standards, Vol. 1. AU section 380), as adopted by the Public Company Accounting Oversight Board in Rule 3200T. The Audit 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 Committee concerning independence. The Audit Committee has also considered and discussed the compatibility of non-audit services provided by BDO with that firm's independence.

COMPENSATION AND OTHER INFORMATION CONCERNING DIRECTORS AND OFFICERS

Compensation Discussion and Analysis

Executive Summary

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

        Our executive compensation programs are 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 to

those of our stockholders. To that end, executive compensation consists of three primary elements: salary, long-term equity interest and a cash bonus opportunity based on annual individual and corporate performance.

        Based on our assessment of the performance of the executives and our compensation philosophy as described in this Compensation Discussion and Analysis, we took the following actions regarding 2012 compensation:

•

Increased the base salaries of Mr. Conroy, Mr. Arora and Dr. Lidgard to $448,900, $330,000 and $330,000, respectively, to bring them in line with the market 25^th percentile;



•

Increased Mr. Conroy's target bonus opportunity from 50% to 60% of base salary to bring his target total cash compensation between the market 25^th and 50^th percentile;



•

Granted annual equity awards to Mr. Conroy, Mr. Arora and Dr. Lidgard at the market 75^th percentile consisting of stock option awards covering 127,500, 52,500 and 52,500 shares, respectively, and performance-based restricted stock unit awards covering up to 142,500, 60,000, and 60,000 shares, respectively; and



•

Awarded cash bonuses to Mr. Conroy, Mr. Arora, Dr. Lidgard and Ms. Stoltenberg of $269,340, $132,000, $132,000 and $97,501, respectively.

        Our executive compensation is discussed in greater detail in the sections that follow. Our Compensation Committee will continue to evaluate our overall compensation structure and awards to ensure that they are reflective of the performance of our executive officers and our Company and are consistent with our compensation objectives.

Objectives of Our Executive Compensation Programs

        Our compensation programs for our executive officers are designed 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, on a long-term basis, talented executives;



•

Provide a total compensation structure that the Compensation Committee believes is at least comparable with similarly-sized companies in the life sciences industry for which we would 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 interest, and a 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 and dental insurance, as well as participation in our 401(k) plan and 2010

Table of Contents

Employee Stock Purchase Plan. We do not believe it is necessary for the attraction or retention of management talent to provide executive officers with compensation in the form of perquisites.

Determining Executive Compensation

        It is the responsibility of the Compensation Committee to administer our compensation practices, to ensure that they are competitive, financially prudent and that they include incentives that are designed to appropriately drive performance. To achieve this, the Compensation Committee periodically reviews commercially available, industry specific compensation data for companies of generally similar employee size and complexity in the biotechnology and diagnostics industries as a general guide for establishing its pay and equity practices and structures. The Compensation Committee, along with the 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, the Compensation 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 in control.

        The Compensation 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 the Compensation Committee relating to the compensation of these officers. Following a review of these recommendations, the Compensation Committee approves the compensation of these officers, with such modifications to the Chief Executive Officer's recommendations as the Compensation Committee considers appropriate.

        The Compensation Committee's review of the Chief Executive Officer's compensation is subject to separate procedures. With input from members of the entire Board of Directors, the Chairman of the Board, along with the Compensation 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, the Compensation Committee then determines the Chief Executive Officer's compensation. The Chief Executive Officer is excused from meetings of the Compensation Committee during voting or deliberations regarding his compensation.

        The Compensation Committee has engaged Radford, an Aon Hewitt Consulting Company ("Radford"), as its independent executive compensation consultant. The Compensation Committee has assessed the independence of Radford pursuant to SEC rules and concluded that no conflict of interest exists that would prevent Radford from serving as an independent consultant to the Compensation Committee.

Analysis of Executive Compensation

        Pursuant to its engagement, in early 2012 Radford provided the Compensation 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 (listed below) that consisted of publicly traded biotechnology and pharmaceutical companies that are similar to the Company in terms

23

---

Table of Contents

of headcount, stage of development and market capitalization and (2) survey data from a broader group of public life sciences companies with headcount between 25 and 250 employees.

        The Compensation 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, the Compensation Committee approved a new peer group for 2012. In its review, Radford focused on creating a peer group that:

•

Represented companies operating in the biotechnology and pharmaceutical industries;



•

Contained a mix of primarily pre-commercial research and development companies and some commercial stage companies;



•

Captured comparable companies in terms of employee size and market capitalization; and



•

Provided sufficient room for growth without over- or under-extending.

        Based on Radford's recommendations, the Compensation Committee (1) removed two companies from the prior year peer group (Icagen and SenoRX) that had been acquired and three companies (EntreMed, Idera Pharma and Palatin Technologies) with market capitalizations below $40 million and (2) and added three companies (AVEO Pharmaceuticals, Idenix Pharmaceuticals and NPS Pharmaceuticals) that met the stated criteria.

        The companies in the peer group were:

Table of Contents

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

•

Base salary levels for the named executive officers were slightly below the 25^th percentile (target philosophy is between 25^th and 50^th percentile).



•

Target total cash compensation (base salary plus annual cash bonus opportunity) levels for the named executive officers were slightly below the 25^th percentile (target philosophy is between 40^th and 50^th percentile).



•

The aggregate value of the long-term incentive compensation awarded to the named executive officers in 2011 (comprised of performance-based restricted stock units) approximated the 50^th percentile.



•

Target total direct compensation (target total cash compensation plus long-term incentive compensation) levels for the named executive officers approximated the 50^th percentile.

        Radford also provided us with an assessment of our annual equity burn rate and the 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 2012 we took the following actions:

•

Increased the base salaries of Mr. Conroy, Mr. Arora and Dr. Lidgard to $448,900, $330,000 and $330,000, respectively, to bring them in line with the market 25^th percentile;



•

Increased Mr. Conroy's target bonus opportunity from 50% to 60% of base salary to bring his target total cash compensation between the market 25^th and 50^th percentile; and



•

Granted annual equity awards to Mr. Conroy, Mr. Arora and Dr. Lidgard at the market 75^th percentile consisting of stock option awards covering 127,500, 52,500 and 52,500 shares, respectively, and performance-based restricted stock unit awards covering up to 142,500, 60,000, and 60,000 shares, respectively.

2012 Bonus Plan

        The Compensation Committee believes that a significant portion of our executives' compensation should be "at risk," i.e., contingent upon successful implementation of our strategy and goals. Accordingly, one component of our executive compensation program is an annual cash bonus opportunity pursuant to 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 and individual performance goals determined by the Compensation Committee in its discretion. In determining 2012 bonus awards, the Compensation Committee considered the executive team's achievement of a variety of business plan goals related to:

•

The clinical trial and related FDA submissions for our Cologuard test;



•

Research and development and operations; and



•

Market development activities.

25

Table of Contents

        After considering the executive team's achievement of key business plan goals, the Compensation Committee determined to award cash bonuses to Mr. Conroy, Mr. Arora, Dr. Lidgard and Ms. Stoltenberg of $269,340, $132,000, $132,000 and $97,501, respectively (100% of target).

Annual Equity Awards

        We believe successful long term Company performance is more critical to enhancing stockholder value than short term results. For this reason and to conserve cash and better align the interests of management and stockholders, we emphasize long term equity compensation over annual salary and incentive compensation awards.

        To provide additional performance-based equity compensation, in February 2012, we made annual equity awards to the executives consisting of performance-based restricted stock unit and stock options. Mr. Conroy, Mr. Arora and Dr. Lidgard received performance-based restricted stock unit awards covering up to142,500, 60,000 and 60,000 shares, respectively. These awards were made subject to performance-based vesting requirements relating to the FDA clinical trial for our Cologuard colorectal cancer and pre-cancer screening test and were subject to forfeiture to the extent these requirements were not satisfied. Based upon the Company's missing by approximately three weeks the target date for completion of the FDA clinical trial for its Cologuard test, none of these awards were earned by the executives. For further information concerning these awards see "2012 Performance RSU Awards" below.

        Mr. Conroy, Mr. Arora and Dr. Lidgard received stock option awards covering 127,500, 52,500 and 52,500 shares, respectively. The shares underlying these options vest and become exercisable in four equal annual installments beginning on the first anniversary of the grant date.

        These awards were intended to further align compensation with achievement of key business plan goals and to motivate the retention of our executives. The Compensation Committee believes that annual equity awards provide the executive officers with the opportunity to acquire long-term stock ownership positions that directly motivates executive officers to maximize long-term stockholder value and that time-based vesting of these awards helps us to retain our leadership team in an extremely competitive environment.

Other Compensation

        We also permit executive officers and other employees to purchase common stock at a discount through our 2010 Employee Stock Purchase Plan. Employees, including 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. The Compensation Committee approved a discretionary matching Company contribution to the plan for 2012. The matching contribution was made using Company stock in an amount equal to 100 percent of an employee's total deferrals into the plan up to a limit of 6% of the employee's total compensation.

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 2012, approximately 94% of the votes cast on the say-on-pay proposal at the meeting were voted in favor of the proposal. The Compensation Committee believes this vote affirms the stockholders'

26

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, the Compensation Committee continues to review and refine the design and administration of our executive pay practices. The Compensation Committee also will continue to consider the outcome of the Company's say-on-pay votes when making future compensation decisions for the named executive officers.

Stock Ownership Guidelines

        In January 2012, the Board of Directors adopted guidelines to encourage ownership of shares of the Company's Common Stock by directors and senior executives. Under these guidelines, directors and senior executives have until the later of five years from the adoption of the guidelines (or, if later, the date of employment, election or promotion, whichever applies) to achieve an ownership target determined as follows:

        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 the Company's 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) the date of adoption of these stock ownership guidelines, and (2) the date of the director's, CEO's or senior executive's hire or appointment, as the case may be, based on the average of the closing prices of the Company's Common Stock for the 30 days leading up to, and inclusive of, the applicable date.

        Shares of the Company's Common Stock that count toward satisfaction of the ownership targets include:

•

Shares directly owned—individual, immediate family or trust (including without limitation shares purchased on the open market or acquired upon the exercise of a stock option);



•

Vested restricted shares, restricted stock units and deferred stock units;



•

"In the money" vested stock options; and



•

Shares held in the Company's 2010 Employee Stock Purchase Plan.

        Shares that do not count toward the ownership targets include:

•

Unvested stock options, restricted shares, restricted stock units, and deferred stock units;



•

"Out of the money" vested stock options; and



•

Performance restricted shares or performance equity units not yet vested.

Employment Agreements with Executive Officers

        In April 2009, Kevin T. Conroy and Maneesh K. Arora joined us as our President and Chief Executive Officer and Senior Vice President and Chief Financial Officer, respectively. On February 16, 2012, Mr. Arora was promoted to Chief Operating Officer in addition to his title of Chief Financial Officer. In August 2009, Graham P. Lidgard joined us as our Senior Vice President and Chief Science Officer. Ms. Stoltenberg joined us as our Chief Commercial Officer in March 2012 and served in that position until April 2013. In April 2013, Ms. Stoltenberg became our Senior Vice President and Chief International Officer. In connection with each of these appointments we entered into an employment agreement under which we agreed to certain compensation arrangements and severance and change in control benefits.

        The compensation packages for Mr. Conroy and Mr. Arora were established by the Compensation Committee with assistance from DolmatConnell & Partners, a compensation consultant. The compensation packages for Dr. Lidgard and Ms. Stoltenberg were designed to be consistent with those of Mr. Conroy and Mr. Arora. Each of these packages was determined based on negotiations with the applicable executive officer and taking into account his or her background and qualifications and the nature of his position. We believe that these compensation packages are appropriate in light of the intense 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 executive officers.

Conroy Employment Agreement

        Mr. Conroy's employment agreement provides for a minimum base salary of $340,000 and for a target bonus opportunity equal to 50 percent 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 the Compensation Committee. 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 NASDAQ Capital Market 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 35 below. The agreement also prohibits Mr. Conroy from engaging in certain activities involving competition with us for an 18-month period following termination of his employment with the Company.

Arora Employment Agreement

        Mr. Arora's employment agreement provides for a minimum base salary of $240,000 and for a target bonus opportunity equal to 40 percent 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 the Compensation Committee. 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 NASDAQ Capital Market on the date Mr. Arora was hired).

        Under his agreement, Mr. Arora 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 35 below. The agreement also prohibits Mr. Arora from engaging in certain activities involving competition with us for an 18-month period following termination of his employment with the Company.

Lidgard Employment Agreement

        Dr. Lidgard's employment agreement provides for a minimum base salary of $275,000 and for a target bonus opportunity equal to 40 percent 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 the Compensation Committee. In addition, Dr. Lidgard received a $70,000 payment to reimburse him for relocation expenses associated with his move to Madison, Wisconsin. 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 NASDAQ Capital Market 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 35 below. The agreement also prohibits Dr. Lidgard from engaging in certain activities involving competition with us for an 18-month period following termination of his employment with the Company.

Stoltenberg Employment Agreement

        Ms. Stoltenberg's employment agreement provided for a minimum base salary of $310,000 and for a target bonus opportunity equal to 40 percent of her 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 the Board and/or the Compensation Committee. In addition, Ms. Stoltenberg received a $100,000 payment to reimburse her for relocation expenses associated with her move to Madison, Wisconsin. Pursuant to her employment agreement, Ms. Stoltenberg also received an initial grant of 165,000 restricted stock units.

        On June 7, 2013 the Company accepted Ms. Stoltenberg's resignation. In connection with her departure we entered into a separation and general release with Ms. Stoltenberg (the "Separation Agreement").

        Under the terms of the Separation Agreement, Ms. Stoltenberg will receive (1) severance payments equal to 12 months of her current annual base salary, (2) a $100,000 guaranteed bonus for

2013, payable in 2014, (3) a payment of $102,500 towards the cost of an outplacement consulting package and relocation assistance, (4) continuation of group health benefits through no later than June 30, 2014, and (5) payment by the Company of Ms. Stoltenberg's reasonable attorneys' fees. Further, pursuant to the Separation Agreement, the Company and Ms. Stoltenberg agreed that Ms. Stoltenberg will retain a total of 100,000 restricted stock units, 41,250 of which vested upon execution of the Separation Agreement, 10,000 of which will vest in March, 2014, and the balance of which will vest in twenty-four equal monthly installments beginning in April, 2014, subject to Ms. Stoltenberg's continuing to provide consulting services pursuant to a separate consulting agreement entered into between Ms. Stoltenberg and the Company. Ms. Stoltenberg forfeited all other restricted stock unit and stock option awards.

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 fully 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.

2012 Performance RSU Awards

        In February 2012 the named executive officers were awarded performance-based restricted stock unit awards ("RSUs") as follows: Mr. Conroy (142,500 RSUs); Mr. Arora (60,000 RSUs) and Mr. Lidgard (60,000 RSUs). Each RSU represented a contingent right to receive one share of our common stock. These RSUs were made subject to the following performance-based vesting conditions. The executives were eligible to earn fifty percent of these awards based upon the Company's completion of the FDA clinical trial for its Cologuard test and meeting trial endpoints as agreed with the FDA (the "Trial Completion Goal") by a specified date. Subject to satisfaction of the Trial Completion Goal, the executives were eligible to earn the remaining fifty percent of these awards based on the achievement of three additional enumerated clinical trial milestones (submission of manufacturing module of premarket approval submission, submission of the analytical and clinical modules of the premarket approval submission and scheduling of an FDA panel approval) by specified dates (with one-third of the remaining amount being earned up completion of each milestone). In July 2012, due to changes in the anticipated timing and sequencing of these clinical trial goals the Compensation Committee approved changing the performance-measurement date for each of the goals from December 31, 2012 to: (1) in the case of the Trial Completion Goal, March 31, 2013, and (2) in the case of the other goals, April 30, 2013. Based on the Company's missing by approximately three weeks the target date for completion of the Trial Completion Goal the executives did not earn any of these RSUs.

Director Compensation

Compensation Policy for Non-Employee Directors

        We maintain a compensation package for our non-employee directors (the "Director Compensation Policy") to enable us to attract and retain, on a long-term basis, high-caliber non-employee directors.

        Pursuant to 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:

42

---

Table of Contents

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

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

        Pursuant to 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 an annual equity award having a value equal to $68,000. This annual equity award is comprised of (1) stock options having a grant date fair value computed in accordance with FASB Accounting Standards Codification Topic 718 ("ASC 718") equal to $34,000 and (2) at the election of the director, either restricted stock or deferred stock units having a grant date fair value computed in accordance with ASC 718 equal to $34,000. If the Chairman of the Board will continue in that role following the date of the annual stockholder meeting, he or she receives an additional annual award having a grant date fair value computed in accordance with ASC 718 equal to $12,500. The Chairman may elect to receive such award in either restricted stock or deferred stock units. These annual equity grants 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.

        Upon his or her initial election to the Board of Directors, a new director receives stock options having a grant date fair value computed in accordance with ASC 718 equal to $102,000. Such options vest in three equal annual installments.

        The foregoing compensation is in addition to reimbursement of all out-of-pocket expenses incurred by directors in attending meetings of the Board of Directors.

        On August 27, 2012, the Company entered into a one year consulting agreement with James P. Connelly under which he provides advisory services in support of the Company's commercialization activities. In accordance with the agreement, Mr. Connelly is paid $5,000 per month for his services and was granted 4,873 restricted stock units on August 27, 2012 that vest in full on the one year anniversary of the grant date.

        As described in detail under the heading "Compensation and Other Information Concerning Directors and Officers—Compensation Discussion and Analysis" beginning on page 21, our executive compensation programs are designed to attract, motivate and retain our executive officers, who are critical to our success. Please read the "Compensation and Other Information Concerning Directors and Officers" section beginning on page 21 for additional details about our executive compensation programs, including information about the 2012 compensation of our named executive officers.

        We are asking our stockholders to indicate their support for our executive compensation programs as described in this proxy statement. This vote is not intended to address any specific term of compensation, but rather the overall compensation of our named executive officers and the philosophy, policies and practices described in this proxy statement. Accordingly, we are asking our stockholders to vote FOR the following resolution at the annual meeting:

•

"RESOLVED, that the compensation paid to the Company's named executive officers, as disclosed pursuant to the SEC's compensation disclosure rules, including the "Compensation Discussion and Analysis", the compensation tables and any related material disclosed in the proxy statement for the Company's 2013 annual meeting, is hereby APPROVED."

        Although the vote on this Proposal 2 regarding the compensation of our named executive officers is not binding on our Board of Directors, we value the opinions of our stockholders and will consider the result of the vote when determining future executive compensation arrangements.

Vote Required for Approval

        The foregoing resolution will be approved if holders of a majority of the shares present or represented at the 2013 Annual Meeting, in person or by proxy, and voting on Proposal 2 vote in favor of such resolution.

Board Recommendation

        The Board recommends that the stockholders vote FOR approval of this Proposal 2.

PROPOSAL 3—APPROVAL OF FIRST AMENDMENT TO 2010 OMNIBUS LONG-TERM
INCENTIVE PLAN

        The Company currently maintains the 2010 Omnibus Long-Term Incentive Plan (the "Omnibus Plan"), which was adopted by our Board of Directors on April 15, 2010, and approved by stockholders at our 2010 Annual Meeting, on July 16, 2010.

        We are asking stockholders to approve an amendment to the Omnibus Plan (the "First Amendment") to add 2,800,000 shares of common stock to the pool of shares available for equity awards and to increase the fungible share ratio to 1.55 (from 1.35). We are also asking stockholders to re-approve individual award limits and business criteria that can be used in establishing performance goals for performance awards granted under the Omnibus Plan for purposes of Section 162(m) of the Internal Revenue Code of 1986, as amended (the "Code").

        Under the Omnibus Plan, the Company initially reserved 4,400,000 shares of common stock for issuance to employees, officers, non-employee directors, consultants and advisors of the Company, or of any affiliate, as the Compensation Committee may determine and designate from time to time, in the form of incentive stock options, non-qualified stock options, stock appreciation rights, restricted stock, restricted stock units, cash- or stock-based performance awards and other stock-based awards. The Omnibus Plan is scheduled to expire on July 16, 2020.

        The Board of Directors believes that the Omnibus Plan is a key part of the Company's compensation philosophy and programs. Our ability to attract, retain and motivate highly qualified officers, non-employee directors, key employees, consultants and advisors is critical to our success. The Board believes that the interests of the Company and its stockholders will be advanced if we can continue to offer our officers, non-employee directors, key employees, consultants and advisors the opportunity to acquire or increase a direct proprietary interest in the operations and future success of the Company.

        As of April 30, 2013, 891,622 shares of common stock remained reserved for issuance pursuant to awards under the Omnibus Plan. As we stated in our Proxy Statement for the 2010 Annual Meeting of Stockholders, when the Omnibus Plan was submitted for stockholder approval in 2010, we expected that the shares reserved for awards at that time would be sufficient to cover our equity awards for at least three years.

        In order to increase the pool of shares available for future equity award grants to continue to operate our compensation program in a manner consistent with past practices and to accommodate anticipated growth, the Board of Directors has adopted, subject to stockholder approval, the First Amendment, to add 2,800,000 shares of common stock to the pool of shares available for equity awards. In connection with increasing the share pool, the First Amendment also increases the fungible share ratio from 1.35 to 1.55, so that each share of common stock covered by an award other than an option or SAR will reduce the share pool by 1.55 shares. For further information concerning the fungible share ratio see "Share Counting" below. Other than the proposed increase to the share pool and the increase to the fungible share ratio, the First Amendment does not make any other changes to the existing Omnibus Plan. We currently anticipate that if the First Amendment is approved, the number of shares reserved for awards under the Omnibus Plan will be sufficient to cover our equity awards for at least the next two years.

Table of Contents

        The following table summarizes information regarding all the Company's outstanding equity awards and shares available for future awards under the company's equity plans as of March 31, 2013.

        The material terms of the Omnibus Plan, as amended by the First Amendment, are summarized below. This summary of the Omnibus Plan is not intended to be a complete description of the Omnibus Plan, as amended by the First Amendment, and is qualified in its entirety by the actual text of the Omnibus Plan, as amended by the First Amendment, which is attached as Appendix A to this proxy statement. The proposed changes to the Omnibus Plan as a result of the First Amendment are set forth in Appendix A.

Material Features of the Omnibus Plan, as Amended by the First Amendment

Administration of the Plan.

        Our Board of Directors has such powers and authorities related to the administration of the Omnibus Plan as are consistent with our corporate governance documents and applicable law. Pursuant to its charter, the Compensation Committee administers the Omnibus Plan.

Type of Awards.

        The following types of awards are available for grant under the Omnibus Plan: incentive stock options ("ISOs"), non-qualified stock options ("NSOs"), stock appreciation rights ("SARs"), restricted stock, restricted stock units, cash- or stock-based performance awards (as defined in the Omnibus Plan) and other stock-based awards.

Number of Authorized Shares.

        Subject to adjustment (in connection with certain changes in capitalization), the number of shares of our common stock reserved for issuance under the Omnibus Plan, as amended by the First Amendment, is equal to: (1) 4,400,000, plus (2) effective upon April 30, 2013 (subject to stockholder approval) 2,800,000. 4,400,000 of such shares of our common stock available for issuance under the Omnibus Plan shall be available for issuance under ISOs. The maximum number of each type of award (other than cash-based performance awards (as defined in the Omnibus Plan)) intended to constitute "performance-based compensation" under Section 162(m) of the Code ("Section 162(m)") granted to any grantee in any 36-month period shall not exceed the following: Options: 4,400,000; SARs: 4,400,000; Restricted Stock: 3,250,000; Restricted Stock Units: 3,250,000; and Other Stock-based Performance Awards: 3,250,000.

Table of Contents

Share Counting.

        The Omnibus Plan uses a "fungible share" concept under which the awards of options and SARs cause one share per covered share to be removed from the available share pool, while the award of restricted stock, restricted stock units, or other stock-based awards where the price charged for the award is less than 100% of the fair market value of our common stock will be counted against the pool as 1.55 shares. This number, known as the "fungible share ratio", is being increased from 1.35 to 1.55, as a result of the First Amendment. The number of shares of common stock available for the purpose of awards under the Omnibus Plan shall be reduced by: (1) the total number of SARs exercised, regardless of whether any of the shares of common stock underlying such awards are not actually issued to the Grantee as the result of a net settlement; and (2) any shares of common stock used to pay any exercise price or tax withholding obligation with respect to any award. Shares of our common stock underlying any outstanding stock option or other award granted under our 2000 Stock Option and Incentive Plan or any other predecessor employee stock plan of the Company that is forfeited, terminated or cancelled for any reason without issuance of such shares shall be available for the grant of new awards under the Omnibus Plan. Any award settled in cash shall not be counted as shares of our common stock for any purpose under the Omnibus Plan. If any award under the Omnibus Plan expires, or is terminated, surrendered or forfeited, in whole or in part, the unissued shares of our common stock covered by such award shall again be available for the grant of awards under the Omnibus Plan. If shares of our common stock issued pursuant to the Omnibus Plan are repurchased by, or are surrendered or forfeited to the Company at no more than cost, such shares of our common stock shall again be available for the grant of awards under the Omnibus Plan. In addition, in the case of any substitute award (as defined in the Omnibus Plan), such substitute award shall not be counted against the number of shares reserved under the Omnibus Plan.

Eligibility and Participation.

        Eligibility to participate in the Omnibus Plan is limited to such employees, officers, non-employee directors, consultants and advisors of the Company, or of any affiliate, as the Compensation Committee may determine and designate from time to time. As of April 30, 2013, approximately 90 employees, four executive officers, seven directors, two consultants and zero advisors would have been eligible to receive awards under the Omnibus Plan.

Stock Options and SARs

        Grant of Options and SARs.    The Compensation Committee may award ISOs, NSOs (together, "options"), and SARs to grantees under the Omnibus Plan. SARs may be awarded either in tandem with or as a component of other awards or alone.

        Exercise Price of Options and SARs.    The exercise price per share of an option will be at least 100% of the fair market value per share of our stock underlying the award on the grant date. A SAR will confer on the grantee a right to receive, upon exercise, a payment of the excess of (1) the fair market value of one share of our stock on the date of exercise over (2) the grant price of the SAR as determined by the Compensation Committee. The grant price will be fixed at the fair market value of a share of stock on the date of grant. SARs granted in tandem with an outstanding option following the grant date of such option will have a grant price that is equal to the option's exercise price; provided, however, that the SAR's grant price may not be less than the fair market value of a share of stock on the grant date of the SAR.

49

---

Table of Contents

        Vesting of Options and SARs.    The Compensation Committee will determine the terms and conditions (including any performance requirements) under which an option or SAR will become exercisable and will include such information in the award agreement.

        Special Limitations on ISOs.    In the case of a grant of an option intended to qualify as an ISO to a grantee that owns more than ten percent of the total combined voting power of all classes of our outstanding stock (a "Ten Percent Stockholder"), the exercise price of the option will not be less than 110% of the fair market value of a share of our stock on the grant date. Additionally, an option will constitute an ISO only (1) if the grantee is an employee of the Company or a subsidiary of the Company, (2) to the extent such option is specifically designated as an ISO in the related award agreement, and (3) to the extent that the aggregate fair market value (determined at the time the option is granted) of the shares of stock with respect to which all ISOs held by such grantee become exercisable for the first time during any calendar year (under the Omnibus Plan and all other plans of the grantee's employer and its affiliates) does not exceed $100,000.

        Exercise of Options and SARs.    An option may be exercised by the delivery to us of written notice of exercise and payment in full of the exercise price (plus the amount of any taxes which we may be required to withhold). The Compensation Committee has the discretion to determine the method or methods by which a SAR may be exercised.

        Expiration of Options and SARs.    Options and SARs will expire at such time as the Compensation Committee determines; provided, however, that no option may be exercised more than ten years from the date of grant, or in the case of an ISO held by a Ten Percent Stockholder, not more than five years from the date of grant.

Restricted Stock and Restricted Stock Units

        Restricted Stock.    At the time a grant of restricted stock is made, the Compensation Committee may establish the applicable "restricted period" and prescribe restrictions in addition to or other than the expiration of the restricted period, including the satisfaction of corporate or individual performance objectives. Unless the Compensation Committee otherwise provides in an award agreement, holders of restricted stock will have the right to vote such stock and the right to receive any dividends declared or paid with respect to such stock. The Compensation Committee may provide that any such dividends paid must be reinvested in shares of stock, which may or may not be subject to the same vesting conditions and restrictions applicable to such restricted stock. All distributions, if any, received by a grantee with respect to restricted stock as a result of any stock split, stock dividend, combination of shares, or other similar transaction will be subject to the restrictions applicable to the original grant.

        The grantee will be required, to the extent required by applicable law, to purchase the restricted stock at a price equal to the greater of (1) the aggregate par value of the shares of stock represented by such restricted stock or (2) the price, if any, specified in the award agreement relating to such restricted stock. If specified in the award agreement, the price may be deemed paid by services already rendered.

        Restricted Stock Units.    A restricted stock unit is a bookkeeping entry representing the equivalent of shares of stock awarded to a grantee. At the time a grant of restricted stock units is made, the Compensation Committee may establish the applicable "restricted period" and prescribe restrictions in addition to or other than the expiration of the restricted period, including the satisfaction of corporate

50

---

Table of Contents

or individual performance objectives. Restricted stock units will not confer stockholder rights to grantees. The Compensation Committee may provide that the holder of restricted stock units will be entitled to receive dividend equivalent rights, which may be deemed reinvested in additional restricted stock units.

Cash- and Stock-Based Performance Awards

        The right of a grantee to exercise or receive a grant or settlement of any award, and the timing thereof, may be subject to such performance conditions as may be specified by the Compensation Committee. The Compensation Committee may use such business criteria and other measures of performance as it may deem appropriate in establishing any performance conditions, and may, subject to certain limitations in the case of a performance award intended to qualify under Section 162(m), exercise its discretion to reduce the amounts payable under any award subject to performance conditions.

        We intend that performance awards granted to persons who are designated by the Compensation Committee as likely to be "Covered Employees" within the meaning of Section 162(m) and regulations thereunder will, if so designated by the Compensation Committee, constitute "qualified performance-based compensation" within the meaning of Section 162(m) and regulations thereunder. The grant, exercise and/or settlement of such performance awards will be contingent upon achievement of pre-established performance goals which will consist of one or more business criteria and a targeted level or levels of performance with respect to each of such criterion. Performance goals will be objective and will otherwise meet the requirements of Section 162(m) and regulations thereunder. In addition, the maximum amount of each cash-based performance award intended to constitute "performance-based compensation" under Section 162(m) granted to a grantee in any 12-month period will not exceed $5,000,000.

        One or more of the following business criteria for the Company will be used exclusively by the Compensation Committee in establishing performance goals for such awards: net sales; revenue; revenue growth or product revenue growth; operating income (before or after taxes); pre-or after-tax income (before or after allocation of corporate overhead and bonuses); net earnings; earnings per share; net income (before or after taxes); return on equity; total stockholder return; return on assets or net assets; appreciation in and/or maintenance of, share price; market share; gross profits; earnings (including earnings before taxes, earnings before interest and taxes or earnings before interest, taxes depreciation and amortization); economic value-added models or equivalent metrics; comparisons with various stock market indices; reduction in costs; cash flows or cash flows per share (before or after dividends); return on capital (including return on total capital or return on invested capital); cash flow return on investment; improvement in or attainment of expense levels or working capital levels; operating margins; gross margins or cash margin; year-end cash; debt reductions; stockholder equity; regulatory performance; implementation, completion or attainment of measurable objectives with respect to research, development, products or projects and recruiting and maintaining personnel; and, to the extent permitted by applicable law, any other business criteria as determined by the Compensation Committee.

Other Stock-Based Awards

        The Compensation Committee may, in its discretion, grant other stock-based awards, consisting of stock units or other awards, valued in whole or in part by reference to, or otherwise based upon, our

51

---

Table of Contents

common stock. The terms of such other stock-based awards will be set forth in the applicable award agreements.

Effect of Certain Transactions.

        Except as otherwise provided in an award agreement (as defined in the Omnibus Plan), in the event of the liquidation or dissolution of the Company or a reorganization, merger, exchange or consolidation of the Company or involving the shares of our common stock (a "transaction"), the Omnibus Plan and the awards issued pursuant to the plan shall continue in effect in accordance with their respective terms, except that following a transaction either (1) each outstanding award will be treated as provided for in the agreement entered into in connection with the transaction or (2) if not so provided in such agreement, each grantee will be entitled to receive in respect of each share of our common stock subject to any outstanding awards, upon exercise or payment or transfer in respect of any award, the same number and kind of stock, securities, cash, property or other consideration that each holder of a share of our common stock was entitled to receive in the transaction in respect of a share of common stock; provided, however, that, unless otherwise determined by the Compensation Committee, such stock, securities, cash, property or other consideration shall remain subject to all of the conditions, restrictions and performance criteria which were applicable to the awards prior to such transaction. Without limiting the generality of the foregoing, the treatment of outstanding options and SARs in connection with a transaction in which the consideration paid or distributed to our stockholders is not entirely shares of common stock of the acquiring or resulting corporation may include the cancellation of outstanding options and SARs upon consummation of the transaction as long as, at the election of the Compensation Committee, (x) the holders of affected options and SARs have been given a period of at least fifteen days prior to the date of the consummation of the transaction to exercise the options or SARs (whether or not they were otherwise exercisable) or (y) the holders of the affected options and SARs are paid (in cash or cash equivalents) in respect of each share covered by the option or SAR being canceled an amount equal to the excess, if any, of the per share price paid or distributed to our stockholders in the transaction (the value of any non-cash consideration to be determined by the Compensation Committee in its sole discretion) over the option or SAR exercise price, as applicable. For avoidance of doubt, (1) the cancellation of options and SARs as described in the preceding sentence may be effected notwithstanding anything to the contrary contained in the Omnibus Plan or any award agreement and (2) if the amount determined pursuant to the preceding sentence is zero or less, the affected option or SAR may be cancelled without any payment therefor.

        Change in Control.    Except as otherwise specifically provided in the applicable award agreement, upon the consummation of a change in control (as defined in the Omnibus Plan): all outstanding awards shall remain the obligation of the Company or be assumed by the surviving or acquiring entity, and there shall be automatically substituted for the shares of our common stock then subject to such 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 shall vest as if the vesting start date with respect to such award was one year prior to the vesting start date set forth in the award agreement relating to such 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 such 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

52

---

Table of Contents

anniversary of the consummation of the change in control: (1) all options outstanding on the date such grantee's employment is terminated, shall 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 such options are subject to repurchase provisions then such repurchase restrictions shall immediately lapse; (2) all restricted stock awards outstanding on the date such grantee's employment is terminated, shall become free of all repurchase provisions; and (3) all other stock-based awards shall become exercisable, realizable or vested in full, or shall be free of all repurchase provisions, as the case may be.

Deferral Arrangements.

        The Compensation Committee may permit or require the deferral of any award payment into a deferred compensation arrangement.

Nontransferability of Awards.

        Generally, during the lifetime of a grantee, only the grantee may exercise rights under the Omnibus Plan and no award will be assignable or transferable other than by will or laws of descent and distribution. If authorized in the award agreement, a grantee may transfer, not for value, all or part of an award (other than an ISO) to certain family members (including trusts and foundations for the benefit thereof). Neither restricted stock nor restricted stock units may be sold, transferred, assigned, pledged or otherwise encumbered or disposed of during the restricted period or prior to the satisfaction of any other restrictions prescribed by the Compensation Committee.

Separation from Service.

        The Compensation Committee may provide in the applicable award agreements for actions that will be taken upon a grantee's separation from service from the Company, including but not limited to, accelerated vesting or termination of awards.

Tax Withholding and Tax Offset Payments.

        We will have the right to deduct from payments of any kind otherwise due to a grantee any federal, state, or local taxes of any kind required by law to be withheld with respect to the vesting of or other lapse of restrictions applicable to an award or upon the issuance of any shares of stock upon the exercise of an option or pursuant to an award.

Term of Plan.

        Unless earlier terminated by our Board of Directors, the authority to make grants under the Omnibus Plan will terminate on July 16, 2020.

Amendment and Termination.

        The Compensation Committee may, at any time and from time to time, amend, suspend, or terminate the Omnibus Plan as to any shares of stock as to which awards have not been made. An amendment will be contingent on approval of our stockholders to the extent stated by our Board of Directors, required by applicable law or required by applicable stock exchange listing requirements. No awards will be made after termination of the Omnibus Plan. No amendment, suspension, or

53

---

Table of Contents

termination of the Omnibus Plan will, without the consent of the grantee, impair rights or obligations under any award theretofore awarded under the Omnibus Plan.

New Plan Benefits.

        All grants of awards under the Omnibus Plan will be discretionary. Therefore, in general, the benefits and amounts that will be received under the Omnibus Plan are not determinable.

Federal Income Tax Consequences.

        The following is a summary of the general federal income tax consequences to the Company and to U.S. taxpayers of awards granted under the Omnibus Plan. Tax consequences for any particular individual or under state or non-U.S. tax laws may be different.

NSOs and SARs.

        No taxable income is reportable when a NSO or SAR is granted. Upon exercise, generally, the recipient will have ordinary income equal to the fair market value of the underlying shares of stock on the exercise date minus the exercise price. Any gain or loss upon the disposition of the stock received upon exercise will be capital gain or loss to the recipient if the appropriate holding period under federal tax law is met for such treatment.

ISOs.

        No taxable income is reportable when an ISO is granted or exercised (except for grantees who are subject to the alternative minimum tax, who may be required to recognize income in the year in which the ISO is exercised). If the recipient exercises the ISO and then sells the underlying shares of stock more than two years after the grant date and more than one year after the exercise date, the excess of the sale price over the exercise price will be taxed as long-term capital gain or loss. If the recipient exercises the ISO and sells the shares before the end of the two- or one-year holding periods, he or she generally will have ordinary income at the time of the sale equal to the fair market value of the shares on the exercise date (or the sale price, if less) minus the exercise price of the ISO.

Restricted Stock and Restricted Stock Units.

        A recipient of restricted stock or restricted stock units will not have taxable income upon the grant unless, in the case of restricted stock, he or she elects to be taxed at that time. Instead, he or she will have ordinary income at the time of vesting equal to the fair market value on the vesting date of the shares (or cash) received minus any amount paid for the shares.

Cash- and Stock-Based Performance Awards and Other Stock-Based Awards.

        Typically, a recipient will not have taxable income upon the grant of cash or stock-based performance awards or other stock-based awards. Subsequently, when the conditions and requirements for the grants have been satisfied and the payment determined, any cash received and the fair market value of any common stock received will constitute ordinary income to the recipient.

54

---

Table of Contents

Tax Effect for the Company.

        We generally will receive a tax deduction for any ordinary income recognized by a grantee in respect of an award under the Omnibus Plan (for example, upon the exercise of a NSO). In the case of ISOs that meet the holding period requirements described above, the grantee will not recognize ordinary income; therefore, we will not receive a deduction.

        Because we are a public company, special rules limit the deductibility of compensation paid to our CEO and to each of our three most highly compensated executive officers other than our CEO whose compensation is required to be reported annually in our proxy statement. Under Section 162(m), the annual compensation paid to each of these executives may not be deductible to the extent that it exceeds $1 million. The limitation on deductions does not apply, however, to qualified "performance-based compensation." Certain awards under the Omnibus Plan, including options, SARs and cash- and stock-based performance awards, may constitute qualified performance-based compensation and, as such, would be exempt from the $1 million limitation on deductible compensation.

Vote Required for Approval

        The First Amendment to the 2010 Omnibus Long-Term Incentive Plan will be approved if holders of a majority of the shares present or represented at the 2013 Annual Meeting, in person or by proxy, and voting on Proposal 3 vote in favor of the First Amendment.

Board Recommendation

        The Board recommends that the stockholders vote FOR approval of the First Amendment to the Omnibus Plan and re-approval of individual award limits and business criteria that can be used in establishing performance goals for performance awards granted under the Omnibus Plan for the purposes of Section 162(m).

PROPOSAL 4—RATIFICATION OF APPOINTMENT OF INDEPENDENT
REGISTERED PUBLIC ACCOUNTING FIRM

        The Audit Committee of the Board of Directors has appointed BDO USA, LLP ("BDO") as our independent registered public accounting firm for the fiscal year ending December 31, 2013. BDO was selected as our independent registered public accounting firm for the fiscal year ending December 31, 2012 following completion of a competitive process to select a firm conducted by the Audit Committee. As a result of this process, on April 26, 2012 the Audit Committee dismissed Grant Thornton LLP ("Grant Thornton") as the Company's independent registered public accounting firm effective upon the filing of the Company's Quarterly Report on Form 10-Q for the quarter ended March 31, 2012. BDO was engaged as the Company's independent registered public accounting firm on April 26, 2012.

        The reports of Grant Thornton LLP on the financial statements of the Company for the past two fiscal years contained no adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles. During the two most recent fiscal years, there were: (1) no disagreements between the Company and Grant Thornton on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Grant Thornton, would have caused Grant Thornton to make reference to the subject matter of the disagreement in their reports on the financial statements for such years, and (2) no "reportable events" as that term is defined in Item 304(a)(1)(v) of Regulation S-K. A representative of Grant Thornton is not expected to be present at the 2013 Annual Meeting.

        During 2010 and 2011, the Company did not consult with BDO regarding (1) the application of accounting principles to a specified transaction or transactions, either completed or proposed, or the type of audit opinion BDO might render on the Company's financial statements or (2) any matter that was either the subject of a disagreement, as that term is defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions to that Item, or a "reportable event" as that term is defined in Item 304(a)(1)(v) of Regulation S-K.

        A representative of BDO is expected to be present at the 2013 Annual Meeting. In addition to having the opportunity to make a statement, the BDO representative will be available to respond to any appropriate questions.

Vote Required for Approval

        Ratification of the appointment of our independent registered public accounting firm requires the affirmative vote of a majority of the shares present or represented at the 2013 Annual Meeting, in person or by proxy, and voting on such ratification. If our stockholders fail to ratify the selection of BDO as the independent registered public accounting firm for 2013, the Audit Committee will reconsider whether to retain that firm. Even if the selection is ratified, the Audit Committee may, in its discretion, direct the appointment of a different independent registered public accounting firm at any time during the year.

Board Recommendation

        The Board recommends that the stockholders vote FOR ratification of the appointment of BDO as our independent registered public accounting firm for 2013.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

        Other than compensation agreements and other arrangements which are described in "Compensation And Other Information Concerning Directors And Officers" beginning on page 21, in 2012 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 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 the Audit 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 the Audit Committee is not feasible, the Audit Committee shall consider the related person transaction and, if the Audit Committee determines it to be appropriate, may ratify the related person transaction. In determining whether to approve or ratify a related person transaction, the Audit 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.

rendering these services. The nature of the services provided for each category is described following the table.

PRE-APPROVAL POLICIES AND PROCEDURES

        The Audit Committee has adopted a policy that requires that all services to be provided by the Company's independent public accounting firm, including audit services and permitted non-audit services, to be pre-approved by the Audit Committee. The Audit Committee approved all audit and permitted non-audit services provided by BDO during 2012 pursuant to this policy.

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, 2012, with the exception of Dr. Lidgard who made one late filing reporting one transaction.
