Dear Stockholder:

On behalf of the Board of Directors of Waters Corporation (“Waters” or the “Company”), I cordially invite you to attend the Annual Meeting of Stockholders (the “Meeting”) of the Company to be held at Waters Corporation, 34 Maple Street, Milford, Massachusetts 01757 on May 11, 2016 at 11:00 a.m., local time.

The notice of Meeting, the Proxy Statement and proxy card from Waters are enclosed. You may also read the notice of Meeting, the Proxy Statement and the Waters Annual Report (“Annual Report”) on the Internet at http://www.proxydocs.com/wat.

Waters has adopted the Securities and Exchange Commission rule allowing companies to furnish proxy materials to their stockholders over the Internet. We believe that this e-proxy process expedites stockholders’ receipt of proxy materials, lowers the costs and reduces the environmental impact of our annual meeting. On April 1, 2016, we mailed to stockholders a Notice of Internet Availability of Proxy Materials (the “Notice”) containing instructions on how to access our Proxy Statement and Annual Report and vote by Internet. The Notice contains instructions on how you can (i) receive a paper copy of the Proxy Statement and Annual Report, if you only received a Notice by mail, or (ii) elect to receive your Proxy Statement and Annual Report over the Internet.

The matters scheduled to be considered at the Meeting are (i) to elect directors to serve for the ensuing year and until their successors are elected, (ii) to ratify the selection of PricewaterhouseCoopers LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2016, (iii) to approve, by non-binding vote, executive compensation and, (iv) to consider and act upon any other matters which may properly come before the Meeting or any adjournment thereof. These matters are more fully explained in the Proxy Statement that you are encouraged to read in its entirety.

The Company’s Board of Directors values and encourages stockholder participation at the Meeting. It is important that your shares be represented, whether or not you plan to attend the Meeting. Please take a moment to vote on the Internet, by telephone, or if you receive a paper copy of the Proxy Statement and Annual Report, signing, dating and returning your proxy card in the envelope provided even if you plan to attend the Meeting.

We hope you will be able to attend the Meeting.

Sincerely,

Christopher J. O’Connell

President and Chief Executive Officer

PROXY STATEMENT

Annual Meeting of Stockholders

May 11, 2016, 11:00 a.m.

This Proxy Statement is being furnished by the Board of Directors (the “Board”) of Waters Corporation (“Waters” or the “Company”), in connection with the Board’s solicitation of proxies (each a “Proxy” and, collectively, “Proxies”), for use at the 2016 Annual Meeting of Stockholders (the “Meeting”) to be held on May 11, 2016 at 11:00 a.m., local time, at the Company’s headquarters located at 34 Maple Street, Milford, Massachusetts 01757. Solicitation of Proxies, which is being made by the Board, may be made through officers and regular employees of the Company by telephone or by oral communications with stockholders following the original solicitation. No additional compensation will be paid to officers or regular employees for such Proxy solicitation. The Company has retained Alliance Advisors, LLC to conduct a broker solicitation for a fee of $7,000, plus reasonable out-of-pocket expenses. Expenses incurred in connection with the solicitation of Proxies will be borne by the Company.

VOTING MATTERS

The representation in person or by Proxy of a majority of the outstanding shares of common stock of the Company, par value $.01 per share, entitled to vote at the Meeting is necessary to provide a quorum for the transaction of business at the Meeting. Shares can only be voted if a stockholder is present in person, has voted via the Internet or by telephone, or is represented by a properly signed Proxy. Each stockholder’s vote is very important. Whether or not you plan to attend the Meeting in person, please vote over the Internet or by telephone or sign and promptly return the Proxy card, which requires no additional postage if mailed in the United States. All signed and returned Proxies will be counted towards establishing a quorum for the Meeting, regardless of how the shares are voted.

Shares represented by Proxy will be voted in accordance with your instructions. You may specify how you want your shares to be voted by voting on the Internet, by telephone, or marking the appropriate box on the Proxy card. If your Proxy card is signed and returned without specifying how you want your shares to be voted, your shares will be voted as recommended by the Board, or as the individuals named as Proxy holders deem advisable on all other matters as may properly come before the Meeting. The Proxy will be voted at the Meeting if the signer of the Proxy was a stockholder of record on March 17, 2016 (the “Record Date”).

Any stockholder voting by Proxy has the power to revoke the Proxy prior to its exercise either by voting by ballot at the Meeting, by executing a later-dated Proxy or by delivering a signed written notice of the revocation to the office of the Secretary of the Company at 34 Maple Street, Milford, Massachusetts 01757 before the Meeting begins.

Representatives of the Company’s independent registered public accounting firm, PricewaterhouseCoopers LLP, are expected to be present at the Meeting. They will have the opportunity to make statements if they desire to do so and will be available to respond to appropriate questions.

As of the Record Date, there were 80,985,209 shares of common stock outstanding and entitled to vote at the Meeting. Each outstanding share of common stock is entitled to one vote. There are no cumulative voting rights. This Proxy Statement and form of Proxy is first being made available to the stockholders of record on or about April 1, 2016. A list of the stockholders entitled to vote at the Meeting will be available for inspection at the Meeting and for ten days prior to the Meeting at the Company’s headquarters for proper purposes relating to the Meeting.

PROPOSAL 1.    ELECTION OF DIRECTORS

Ten members of the Board (the “Directors”) are to be elected at the Meeting, each to hold office until his or her successor is elected and qualified or until his or her earlier resignation, death or removal.

Required Vote and Recommendation of the Board of Directors

With respect to the election of Directors of the Company, a nominee for director shall be elected to the Board by a majority vote (i.e. the votes cast for such nominee must exceed the votes cast against such nominee), except that Directors will be elected by plurality vote at any meeting of stockholders for which the number of nominees exceeds the number of directors to be elected (a contested election). If an incumbent director fails to be re-elected by a majority vote when such a vote is required and offers to resign, and if that resignation is not accepted by the Board, such director shall continue to serve until the next annual meeting and until his or her successor is duly elected, or his or her earlier resignation or removal. If an incumbent director’s resignation is accepted by the Board, or if a nominee for director is not elected and the nominee is not an incumbent director, then the Board, in its sole discretion, may fill any resulting vacancy or may decrease the size of the Board. “Abstentions” and shares with respect to which a broker or representative does not vote on a particular matter because it does not have discretionary voting authority on that matter (so-called “broker non-votes”) are counted as present for the purpose of determining whether a quorum is present. Abstentions and broker non-votes will not be treated as shares cast with respect to any nominee and therefore will not have an effect on the determination of whether a nominee has been elected.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” EACH NOMINEE FOR DIRECTOR SET FORTH ABOVE.

PROPOSAL 2. RATIFICATION OF SELECTION OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

The Audit Committee of the Board has selected PricewaterhouseCoopers LLP (“PWC”), an independent registered public accounting firm, to audit the books, records and accounts of the Company for the fiscal year ending December 31, 2016. In accordance with a vote of the Audit Committee and as approved by the Board, this selection is being presented to the stockholders for ratification at the Meeting.

Required Vote and Recommendation of the Board of Directors

The affirmative vote of a majority of the shares present at the Meeting in person or represented by Proxy and entitled to vote is required to approve the proposal. Abstentions will be counted as present for the purpose of determining whether a quorum is present and will be treated as shares present and entitled to vote and therefore will have the effect of a vote against the proposal. Ratification by stockholders is not required. Brokerage firms may vote to ratify the appointment of PWC as it is a “discretionary” or “routine” item. If this Proposal 2 is not approved by the stockholders, the Audit Committee does not intend to change the appointment for fiscal year 2016, but will consider the stockholder vote in selecting an independent registered public accounting firm for fiscal year 2017.

Fees

The aggregate fees for the fiscal years ended December 31, 2015 and December 31, 2014 billed by PWC were as follows:

Audit-Related Fees — consists of fees for assurance and related services that are reasonably related to the performance of the audit or review of the Company’s consolidated financial statements and are not reported under “Audit Fees”. These services include statutory audits, employee benefit plan audits, acquisition-related services, attest services not required by statute or regulation, and accounting consultations and reviews for various matters.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THE RATIFICATION OF THE SELECTION OF PRICEWATERHOUSECOOPERS LLP AS THE COMPANY’S INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM.

PROPOSAL 3. NON-BINDING VOTE ON EXECUTIVE COMPENSATION

Under the Dodd-Frank Wall Street Reform and Consumer Protection Act (the “Dodd-Frank Act”), the stockholders of Waters are entitled to cast an advisory vote at the Meeting to approve the compensation of the Company’s named executive officers, as disclosed in this proxy statement. Pursuant to the Dodd-Frank Act, the stockholder vote is an advisory vote only and is not binding on Waters or the Board. Stockholders have elected to conduct this vote annually.

Although the vote is non-binding, the Compensation Committee and the Board value your opinions and will consider the outcome of the vote in establishing and evaluating the Company’s compensation philosophy and making future compensation decisions.

As described more fully in the Compensation Discussion and Analysis, the Summary Compensation Table and the other tables following the Summary Compensation Table, the Company’s named executive officers are compensated in a manner consistent with our business strategy, competitive practice, sound compensation governance principles, and stockholder interests and concerns.

• Our compensation policies and decisions are focused on pay-for-performance.

• Annual performance targets are comprised of challenging operational and financial goals.

• Named executive officers had an annual performance target under the annual Management Incentive Plan of 15% non-GAAP earnings per diluted share (“E.P.S.”) growth for 2015.

• Target non-GAAP E.P.S. performance of 15% growth has been achieved in twelve of the past twenty years and Waters has delivered an annual compounded non-GAAP E.P.S. growth rate of 11% over the past ten years.

• In 2015, the Company achieved 7% non-GAAP E.P.S. growth despite the significant negative impact of foreign currency translation. Without the negative impact of currency, non-GAAP E.P.S. growth would have been 18%. Taking the impact of foreign currency translation into account, the Compensation Committee approved payouts under the Management Incentive Plan for 2015 equal to 84% of the target payout to our named executive officers.

8

A description of the elements of GAAP and non-GAAP items can be found below the caption, Compensation of Directors and Executive Officers, Elements of Executive Compensation, Annual Incentive. A reconciliation of GAAP to non-GAAP E.P.S. and non-GAAP operating income can be found on the Company’s website at http://www.waters.com under the caption “Investors” and copies may be obtained, without charge, upon written request to the Company, c/o Vice President, Investor Relations, 34 Maple Street, Milford, MA 01757.

Waters also has several compensation governance programs in place as described in the Compensation Discussion and Analysis to manage compensation risk and align Waters’ executive compensation with long-term stockholder interests. These programs include:

• Stock ownership guidelines;

• a policy against hedging;

• an independent compensation committee and compensation committee consultant;

• a compensation recoupment policy; and

• a balanced program that does not include perquisites and guaranteed payments as a significant source of compensation.

We are requesting your non-binding vote on the following resolution:

“Resolved, that the compensation of the Company’s named executive officers as described in the Compensation Discussion and Analysis, in the Summary Compensation Table and subsequent tables, is approved.”

Required Vote and Recommendation of the Board of Directors

The affirmative vote of a majority of the shares present or represented by Proxy and entitled to vote, is required for approval, on an advisory basis, of this proposal. If you own shares through a bank, broker or other holder of record, you must instruct your bank, broker or other holder of record how to vote in order for them to vote your shares so that your vote can be counted on this proposal. Abstentions will have the effect of a vote against this proposal. Note: Broker non-votes will have no effect on this proposal.

THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THE RESOLUTION.

PROPOSAL 4. OTHER BUSINESS

The Board does not know of any other business to be presented at the Meeting. If any other matters properly come before the Meeting, however, it is intended that the persons named in the enclosed form of Proxy will vote said Proxy in accordance with their best judgment.

DIRECTORS MEETINGS AND BOARD COMMITTEES

Meetings

The Board held seven meetings during the year ended December 31, 2015. The Board has determined that each Director other than Mr. Berthiaume, the Company’s Chairman and Mr. O’Connell, President and Chief Executive Officer, has no material relationship with the Company and otherwise qualifies as “independent” under applicable listing standards of the New York Stock Exchange and the Company’s independence criteria, which are summarized under “Corporate Governance — Board/Director Independence” below.

During 2015, each of the Company’s Directors attended in excess of 75% of the aggregate of the meetings of the Board and the meetings of committees of the Board of which such Director was a member. During fiscal year 2015, the Compensation Committee met four times, the Audit Committee met eight times and the Nominating and Corporate Governance Committee met twice. The Company does not have a formal policy, but encourages Director attendance at annual stockholder meetings. All Directors attended the 2015 annual meeting of stockholders.

Nominating and Corporate Governance Committee

The Nominating and Corporate Governance Committee currently consists of Dr. Michael J. Berendt (Chair), Dr. Laurie H. Glimcher, and Mr. Thomas P. Salice. The responsibilities of the Nominating and Corporate Governance Committee include the recruitment and recommendation of candidates for the Board. The Nominating and Corporate Governance Committee may, as it deems appropriate, give consideration to any candidates suggested by the stockholders of the Company. The Nominating and Corporate Governance Committee also develops and recommends to the Board the Corporate Governance Guidelines for the Company. The charter of the Nominating and Corporate Governance Committee, which sets forth all of the Nominating and Corporate Governance Committee’s functions, is available on the Company’s website at http://www.waters.com under the caption “Corporate Governance”.

CORPORATE GOVERNANCE

Annual Evaluation

During 2015, the Nominating and Corporate Governance Committee of the Board conducted its annual evaluation of the Board and each of its committees. The evaluation, in the form of a questionnaire, was circulated to all members of the Board and each committee in November 2015. The Company’s General Counsel received all of the questionnaires, compiled the results and circulated them to the Board and each committee for discussion and analysis during January 2016. It is the intention of the Nominating and Corporate Governance Committee to continue to engage in this process annually.

Related Party Transactions Policy

The Board has adopted a written Related Party Transactions Policy, which covers “Interested Transactions” between a “Related Party” or parties and the Company. An Interested Transaction is a transaction or arrangement in which the aggregate amount involved will or may be expected to exceed $120,000 in any calendar year and in which the Company and/or any Related Party may have an interest. A Related Party includes an executive officer, director or nominee for election as a director of the Company, any holder of more than a 5% beneficial ownership interest in the Company, any immediate family member of any of the foregoing or any firm, corporation or entity in which any of the foregoing persons is employed or is a general partner or principal or in which such person or persons collectively have a 10% or greater beneficial ownership interest.

Pursuant to the policy, the General Counsel is responsible for identifying potential Interested Transactions and determining whether a proposed transaction is an Interested Transaction and accordingly, reportable to the Nominating and Corporate Governance Committee for consideration at its next regularly scheduled meeting. The Nominating and Corporate Governance Committee will review the material facts of all Interested Transactions and report its recommendations to the Board which will either approve or disapprove the Interested Transaction.

The Nominating and Corporate Governance Committee and the Board have reviewed and determined that certain categories of Interested Transactions are deemed to be pre-approved or ratified (as applicable) by the Board under the terms of the policy. These are: (a) the employment and compensation arrangements of named executive officers (as defined below) required to be reported in the Company’s Proxy Statement; (b) Director compensation required to be reported in the Company’s Proxy Statement; (c) ordinary course charitable contributions periodically reviewed by the Compensation Committee of the Board; and (d) ordinary course business transactions conducted on an “arm’s length” basis with Bristol-Myers Squibb Corporation (of which Dr. Glimcher is a director).

Eugene G. Cassis, Vice President and Chief Financial Officer, is married to Mary Dwyer-Cassis who has been employed by the Company since 1986, well before Eugene G. Cassis’ appointment as acting Chief Financial Officer in 2014. Mary Dwyer-Cassis is employed by the Company as the General Manager North District with a total 2015 annual salary, commission, equity awards and retirement benefits of approximately $300,000.

Equity Ownership Guidelines

Increasingly, stockholders of public companies are focusing on the amount of equity ownership by directors and officers of the companies in which they invest. In order to more closely align the interests of the Company’s stockholders with those of management, the Company has minimum stock ownership guidelines for Directors and named executive officers. These guidelines provide for the accumulation by anyone who holds the Chief Executive Officer position of common stock equal to five times his or her base salary over a three-year period. Additionally, the Company’s other named executive officers on December 31, 2015, Messrs. Caputo, Cassis and Beaudouin and Ms. Rae, are each required to accumulate common stock equal to two times their base salary. Pursuant to the guidelines, members of the Board are required to accumulate a minimum of 5,000 shares of common stock of the Company.

If, as the case may be, a named executive officer shall become non-compliant with the guidelines, he or she shall have a period of twelve (12) months to regain compliance with the guidelines. If, after such twelve month period, the named executive officer remains non-compliant, then, with respect to any subsequent exercise of a

11

stock option by such executive officer, 50% of such executive’s net after-tax profit from such exercise must be retained in shares of common stock until compliance with the guidelines is achieved. Exceptions to these equity ownership guidelines may be considered by the Nominating and Corporate Governance Committee with respect to individual financial situations of current or future executives covered by the guidelines. For purposes of the accumulation of shares of common stock to comply with these guidelines, in addition to any direct ownership of shares of common stock by a named executive officer or Director, any shares of restricted stock and vested “in-the-money” stock options, which either were or will be granted by the Company to such executives or Directors, apply toward the satisfaction of the guidelines. The ownership guidelines have been met by all Directors and named executive officers except for Mr. O’Connell who is in the process of meeting the ownership guidelines.

Board Leadership Structure

As stated in the Company’s Corporate Governance guidelines, the Board has no set policy with respect to the separation of the offices of Chairman and Chief Executive Officer, but instead makes a particular determination in the context of selecting a chief executive officer. Douglas A. Berthiaume served as both Chairman of the Board and Chief Executive Officer from 1996 until September 2015 at which time Christopher J. O’Connell became President and Chief Executive Officer. Following Mr. O’Connell’s appointment, the offices of Chairman and Chief Executive Officer have been separated.

Since 2004, Thomas P. Salice, an independent director, has served as the Board’s “lead independent director”. In that capacity, he has presided over executive sessions of the non-management Directors of the Board and provided a focal point for and facilitated communication among non-management Directors, Company management and Company stockholders.

The lead independent director continues to facilitate independent and effective oversight of the Company’s affairs.

Majority Voting

The Company’s by-laws provide for majority voting for Directors in uncontested elections. A further description of the Company’s majority voting provisions can be found under “Proposal 1. Election of Directors” herein.

Guidelines and Code of Conduct

The Board has adopted Corporate Governance Guidelines, a Code of Business Conduct and Ethics for employees, executive officers and Directors and a “whistleblower” policy regarding the treatment of complaints on accounting, internal accounting controls and auditing matters. All of these documents are available on the Company’s website at http://www.waters.com under the caption “Corporate Governance” and copies may be obtained, without charge, upon written request to the Company, c/o Secretary, 34 Maple Street, Milford, MA 01757.

Policy Against Hedging

In 2013, the Board adopted a policy prohibiting Directors, officers and certain key employees from purchasing financial instruments, including prepaid variable forward contracts, equity swaps, collars, or units of exchange funds, that are designed to hedge or offset any decrease in market value of equity securities of the Company. This prohibition does not apply to any bona fide pledge of equity securities of the Company, not made for the purpose of hedging.

Board Candidates

With respect to potential candidates to serve on the Board, the Nominating and Corporate Governance Committee considers suggestions from a variety of sources, including stockholders. Any nominations of candidates, together with appropriate biographical information, should be submitted in accordance with the Company’s by-laws to the Company, c/o Secretary, 34 Maple Street, Milford, MA 01757.

12

The Nominating and Corporate Governance Committee believes that candidates for service as a Director of the Company should meet certain minimum qualifications. In selecting Directors, the Board seeks individuals who are highly accomplished in their respective fields, with superior educational and professional credentials. Candidates should satisfy the Company’s independence criteria, which are part of its Corporate Governance Guidelines and summarized below and the applicable listing standards of the New York Stock Exchange. In assessing candidates for Director, the Nominating and Corporate Governance Committee will consider their skills, experience and diversity in the context of the overall composition of the Board.

The Company has a process for identifying and selecting candidates for Board membership. Initially, the Chairman, Chief Executive Officer, the Nominating and Corporate Governance Committee or other Board members identify a need to either expand the Board with a new member possessing certain specific characteristics or to fill a vacancy on the Board. A search is then undertaken by the Nominating and Corporate Governance Committee, working with recommendations and input from Board members, members of senior management, professional contacts, external advisors, nominations by stockholders and/or the retention of a professional search firm, if necessary. An initial slate of candidates is identified that will satisfy the criteria for Board membership and is presented to the Nominating and Corporate Governance Committee for review. Upon review by the Nominating and Corporate Governance Committee, a series of interviews of one or more candidates is conducted by the Chairman, Chief Executive Officer and at least one member of the Nominating and Corporate Governance Committee. During this process, the full Board is informally apprised of the status of the search and its input is solicited.

Upon identification of a final candidate, the entire Nominating and Corporate Governance Committee will meet to consider the credentials of the candidate and thereafter, if approved, will submit the candidate for approval by the full Board.

As noted above, the Nominating and Corporate Governance Committee, in assessing candidates for director, considers their skills, experience and diversity in the context of the Board’s overall composition. The Company does not, however, have a specific policy with respect to the consideration of diversity in identifying director nominees.

Board/Director Independence

The Company’s Corporate Governance Guidelines include criteria adopted by the Board to assist it in making determinations regarding the independence of its members. Our Categorical Standards of Independence are also available on the website www.waters.com under the caption “Corporate Governance”. The criteria, summarized below, are consistent with the New York Stock Exchange listing standards regarding director independence. To be considered independent, the Board must determine that a director does not have a material relationship, directly or indirectly, with the Company. A director will not be considered independent if he or she, or an immediate family member, has been within the last three years:

• an executive officer of the Company;

• a current partner or employee of an internal or external auditor of the Company or a partner or employee of an internal or external auditor of the Company who personally worked on the Company’s audit;

• an executive officer of a public company that was on the compensation committee of its board;

• a paid advisor or consultant to the Company receiving in excess of $100,000 per year in direct compensation from the Company (other than fees for service as a director) within the past three years or has an immediate family member who has been a paid advisor or consultant to the Company; and

• an employee (or in the case of an immediate family member, an executive officer) of a company that does business with the Company and the annual payments to or from the Company exceeded the greater of $1 million or 2% of the other company’s annual gross revenues.

In addition, a director will not be considered independent if he or she, or an immediate family member, has been an executive officer of a tax-exempt entity that receives contributions in any fiscal year from the Company exceeding the greater of $1 million or 2% of its gross revenues. A director also will not be considered

13

independent if he or she has an immediate family member who is a current employee of an internal or external auditor of the Company who participates in such firm’s audit, assurance or tax compliance practice.

The Board has determined that each Director, other than Mr. Berthiaume, the Company’s Chairman, and Mr. O’Connell, the Company’s President and Chief Executive Officer, has no material relationship with the Company and otherwise qualifies as “independent” under these criteria and the applicable listing standards of the New York Stock Exchange.

Stockholder and Board Communications

With respect to communications with the Board on general matters, stockholders and interested parties may communicate directly with the lead director or with the non-management Directors as a group by writing to Waters Corporation, c/o Secretary, 34 Maple Street, Milford, Massachusetts 01757. Any such communication should include the name and return address of the stockholder, the specific Director or Directors to whom the contact is addressed and the nature or subject matter of the contact. All communications will be sent directly to the appropriate Board member.

REPORT OF THE AUDIT COMMITTEE OF THE BOARD OF DIRECTORS

The information contained in this report shall not be deemed to be “soliciting material” or “filed” or incorporated by reference in future filings with the SEC, or subject to the liabilities of Section 18 of the Exchange Act, except to the extent that Waters specifically incorporates it by reference into a document filed under the Securities Act of 1933 or the Exchange Act.

During 2015, the Audit Committee of the Board, in conjunction with management and PricewaterhouseCoopers LLP, the Company’s independent registered public accounting firm, focused on the following items:

1. Compliance with Section 404 of the Sarbanes-Oxley Act of 2002 (the “Act”) and the adequacy of Company internal controls;

2. The appropriateness of Company financial reporting and accounting processes;

3. The independence and performance of the Company’s independent registered public accounting firm;

4. Company compliance with laws and regulations, including compliance with applicable provisions of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010; and

5. Review of the Company’s independent registered public accounting firm’s quality control procedures.

The Company retains Ernst &Young LLP to assist in elements of continuing compliance with Section 404 of the Act. The Company’s compliance with Section 404 of the Act is managed primarily by the Company’s Vice President, Audit & Risk Management in conjunction with the Company’s Vice President, Chief Financial Officer and its Vice President, Corporate Controller. During 2015, the Audit Committee received regular and detailed briefings from the Company’s Vice President, Audit & Risk Management and PricewaterhouseCoopers LLP regarding the Company’s compliance with Section 404 of the Act. On February 23, 2016, the Company’s Vice President, Audit & Risk Management and PricewaterhouseCoopers LLP reported to the Audit Committee that no material weaknesses had been identified in the Company’s internal controls over financial reporting as of December 31, 2015.

The Board has adopted a written charter setting out more specifically the functions that the Audit Committee is to perform. The charter is reviewed on an annual basis by the Audit Committee and the Audit Committee is advised as to any corporate governance developments which may warrant charter amendments. No such charter amendments were made in 2015. The charter is available on the Company’s website at http://www.waters.com under the caption “Corporate Governance”. A discussion of the Audit Committee’s role in risk oversight can be found under the heading “Risk Oversight – Board’s Role in Risk Oversight Generally” below.

As stated in its charter, the Audit Committee is tasked with, among other things, reviewing with management the Company’s guidelines and policies with respect to its approach to risk assessment and risk management. In addition, major financial risk exposures and means of monitoring and controlling these exposures, is to be discussed with management.

The Audit Committee held eight meetings during the fiscal year ended December 31, 2015. The Audit Committee reviewed on a quarterly basis, with members of the Company’s management team, the Company’s quarterly and annual financial results prior to the release of earnings and the filing of the Company’s quarterly and annual financial statements with the SEC. The Board has determined that each of the four current members of the Audit Committee — Mr. Salice (Chair), Mr. Conard, Mr. Miller and Ms. Reed — is an “audit committee financial expert” as defined under applicable rules and regulations of the SEC and has “accounting or related financial management expertise” within the meaning of the New York Stock Exchange rules. Company management has primary responsibility for the financial statements and reporting processes. The Company’s independent registered public accounting firm, PricewaterhouseCoopers LLP, audits the annual financial statements and is responsible for expressing an opinion on their conformity with generally accepted accounting principles.

15

The Audit Committee has adopted the following guidelines regarding the engagement of PricewaterhouseCoopers LLP to perform non-audit services for the Company:

Company management will submit to the Audit Committee for approval a list of non-audit services that it recommends the Audit Committee engage its independent registered public accounting firm to provide from time to time during the fiscal year and an estimated amount of fees associated with such services. Company management and the Company’s independent registered public accounting firm will each confirm to the Audit Committee that each non-audit service on the list is permissible under all applicable legal requirements. The Audit Committee will, in its discretion, either approve or disapprove both the list of permissible non-audit services and the estimated fees for such services. The Audit Committee will be informed routinely as to the non-audit services actually provided by the Company’s independent registered public accounting firm pursuant to this pre-approval process and the actual expenditure of fees associated therewith as well as new non-audit services being requested for approval.

To ensure prompt handling of unexpected matters, the Audit Committee delegates to its Chairman the authority to amend or modify the list of approved permissible non-audit services and fees. The Chairman will report action taken to the Audit Committee at the next Audit Committee meeting.

PricewaterhouseCoopers LLP and the Company ensure that all audit and non-audit services provided to the Company have been pre-approved by the Audit Committee.

The Audit Committee hereby reports for the fiscal year ended December 31, 2015 that:

1. It has reviewed and discussed the Company’s audited financial statements for the fiscal year ended December 31, 2015 with Company management;

2. It has reviewed and discussed with PricewaterhouseCoopers LLP those matters required to be communicated by PricewaterhouseCoopers LLP to the Audit committee, including under Auditing Standard No. 16, as adopted by the Public Company Accounting Oversight Board (“PCAOB”);

3. It has received from PricewaterhouseCoopers LLP written disclosures and a letter required by the applicable requirements of the PCAOB regarding PricewaterhouseCoopers LLP’s communications with the Audit Committee concerning independence, and has discussed with PricewaterhouseCoopers LLP its independence;

4. It has considered whether, and determined that, the provision of non-audit services to the Company by PricewaterhouseCoopers LLP as set forth below, was compatible with maintaining auditor independence; and

5. It has reviewed and discussed with PricewaterhouseCoopers LLP its internal quality control procedures, and any material issues raised by the most recent internal quality control review, or peer review, or by any inquiry or investigation by governmental or professional authorities within the preceding five years.

Based on the items reported above, on February 23, 2016, the Audit Committee recommended to the Board that the Company’s audited financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2015 for filing with the SEC. The recommendation was accepted by the Board on the same date.

Mr. Thomas P. Salice Mr. Edward Conard Mr. William J. Miller Ms. JoAnn A. Reed

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

The Compensation Committee currently consists of Mr. Joshua Bekenstein, Mr. Christopher A. Kuebler, Mr. William J. Miller (Chair), and Mr. Thomas P. Salice. During fiscal year 2015, no member of the Compensation Committee was an officer or employee of the Company or served as a member of the Board or Compensation Committee of any entity that has one or more executive officers serving as members of the Waters Board or its Compensation Committee and no executive officer of the Company served on the Compensation Committee or Board of Directors of any entity that has one or more executive officers serving on the Waters Board or Compensation Committee.

RISK OVERSIGHT

Board’s Role in Risk Oversight Generally

Included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2015 are the risk factors affecting the Company which are periodically reviewed by the Board and the Audit Committee and updated or expanded as warranted. The Board is responsible for overseeing the management and operations of the Company, including its risk assessment and risk management functions. The Board has delegated responsibility to reviewing the Company’s policy with respect to risk assessment and management to the Audit Committee.

Additionally, the Company has an Enterprise Risk Management program under the direction of the Director of Treasury and Risk Management and the Vice President, Audit & Risk Management. This program seeks to identify, assess, monitor and report on risks affecting the Company’s business and operations on an ongoing basis. Management of the Company actively participates in this program and briefs the Audit Committee on the risks affecting the Company and efforts undertaken to mitigate them. The Compensation Committee has responsibility for oversight of risk related to compensation matters as more fully described below.

Compensation-Related Risk

The Compensation Committee conducted a review to determine if any compensation plans and practices would be reasonably likely to have a material adverse effect on the Company. The Compensation Committee reviewed various components of the Company’s compensation plans including their size, scope and design. The Compensation Committee also reviewed whether the compensation plans promote unnecessary risk taking and the policies in place to mitigate compensation risk. The review included an assessment of design features that could encourage excessive risk-taking and the potential magnitude of such risks, including design features such as a short-term oriented pay mix, overly aggressive goal setting and over-weighting of annual incentives. Several features of the Company’s annual incentive plan, the Management Incentive Plan, mitigate compensation-related risk including the use of payout caps, a clear link between payouts under the plan and the Company’s financial performance, and Compensation Committee oversight in determining payouts under the Plan. The policies that exist to mitigate compensation-related risk include, among others, (1) the Company’s Recoupment Policy for Management Incentive Plan awards; (2) stock ownership guidelines for named executive officers; (3) a five-year vesting provision for long-term incentive awards; (4) a prohibition on hedging; and (5) independent oversight of compensation programs by the Compensation Committee with input from an independent compensation consultant. Based on this review, the Compensation Committee and the Company do not believe that there are any compensation related risks arising from the Company’s compensation plans that would have a material adverse effect on the Company.

Role of Compensation Consultant, Compensation Committee and Management in Decision-Making

The Compensation Committee engaged the services of Pearl Meyer & Partners as its outside independent compensation consultant during fiscal year 2015. Pearl Meyer & Partners participates in Compensation Committee meetings and executive sessions and advises the Compensation Committee on a range of executive officer and director compensation matters including plan design, competitive market assessments, trends, best practices and technical and regulatory developments. Pearl Meyer & Partners provides services to the Compensation Committee related only to executive officer and director compensation, including defining peer groups, compar-

17

ing executive officer and director compensation arrangements to those of the peer groups, and providing market data and advice regarding executive and director compensation plans. The Compensation Committee has the authority to engage and terminate independent legal, accounting and other advisors as it deems necessary or appropriate to carry out its responsibilities.

The Compensation Committee regularly reviews the services provided by its outside consultants and believes that Pearl Meyer & Partners is independent in providing executive compensation consulting services. The Compensation Committee conducted a specific review of its relationship with Pearl Meyer & Partners in 2015, and determined that Pearl Meyer & Partners’ work for the Compensation Committee did not raise any conflicts of interest, considering the factors set forth in applicable SEC and New York Stock Exchange Rules. The Compensation Committee continues to monitor the independence of its compensation consultant on a periodic basis.

The Compensation Committee approves all compensation decisions for the named executive officers, after consulting with Pearl Meyer & Partners, as appropriate. The Vice President of Human Resources also provides the Compensation Committee with information and analysis on the Company’s executive compensation programs as requested. During 2015, Messrs. Berthiaume and O’Connell each provided the Compensation Committee with their assessment of the performance of the Company and the other named executive officers, and made compensation recommendations for the other named executive officers. The Compensation Committee, however, makes all final decisions with respect to the compensation of the CEO and the other named executive officers. No named executive officer makes any decision on any element of his or her own compensation.

COMPENSATION OF DIRECTORS AND EXECUTIVE OFFICERS

Compensation Discussion and Analysis

Overview

This Compensation Discussion and Analysis discusses the compensation programs for our named executive officers. Our named executive officers for fiscal year 2015 were as follows:

• Christopher J. O’Connell, President and Chief Executive Officer (“CEO”);

• Douglas A. Berthiaume, Chairman, Former President and CEO;

• Eugene G. Cassis, Senior Vice President Finance and Administration and Chief Financial Officer;

• Arthur G. Caputo, Former Executive Vice President and President, Waters Division;

• Mark T. Beaudouin, Senior Vice President, General Counsel and Secretary; and

• Elizabeth B. Rae, Senior Vice President, Human Resources.

On September 8, 2015, Douglas A. Berthiaume, our Chairman, President and CEO, retired from his position as President and CEO. Mr. Berthiaume remained a non-executive employee of the Company until December 31, 2015, and remains Chairman of the Board. Effective September 8, 2015, Christopher O’Connell commenced employment with the Company as our President and CEO. A description of the arrangements entered into with Mr. O’Connell when he commenced employment with us is included below. Although Mr. Berthiaume is a former employee, he is included as a named executive officer in this discussion and the accompanying tables pursuant to SEC rules. Effective February 10, 2016, Mr. Caputo resigned from his position as Executive Vice President and President, Waters Division, and will remain a non-executive employee of the Company through January 2017.

Executive Summary

The following is a summary of Company performance, the impact of Company performance on the compensation for our named executive officers, governance practices related to our compensation programs and the impact of results of the 2015 Say on Pay vote. Details of our compensation programs are discussed in further detail in the appropriate sections of this Compensation Discussion and Analysis:

2015 Company Performance and Events

• Our full-year sales growth was 9% before a constant currency basis and 3% after taking into account the negative impact of foreign currency translation.

• Our non-GAAP E.P.S.⁽²⁾ grew 7% to $5.89 from $5.48 in 2014. Without the negative impact of foreign currency translation, non-GAAP E.P.S would have grown 18%.

• During 2015, the Company’s stock price grew 19%.

(2) A description of the elements of GAAP and non-GAAP items can be found below in the section Elements of Executive Compensation, Annual Incentive. A reconciliation of GAAP to non-GAAP E.P.S. and non-GAAP operating income can be found on the Company’s website at http://www.waters.com under the caption “Investors” and copies may be obtained, without charge, upon written request to the Company, c/o Vice President, Investor Relations, 34 Maple Street, Milford, MA 01757.

Impact of Company Performance on Compensation

Consistent with our pay-for-performance philosophy, the following actions and decisions were taken in 2015 as a result of Company performance:

• Base Salaries: The Compensation Committee approved a 5% increase to the base salary for each named executive officer (other than Mr. O’Connell), effective on January 1, 2015. The decision to increase base salaries was based on an improving economic environment and market data provided by Pearl Meyer & Partners which indicated that base salaries for executives increased on average 5% in 2014. The Compensation Committee also approved additional market adjustment increases for Mr. Cassis and Ms. Rae of 7%

19

and 6%, respectively, in order to position their base salaries at a more competitive level relative to the market and, in each case, closer to the 25^th percentile of the market data. Our use of market data is described below. Mr. O’Connell’s base salary was separately negotiated when he commenced employment with the Company on September 8, 2015.

• Annual Incentive Plan: Our annual cash incentive plan, the Management Incentive Plan, provides for incentive opportunities that are aligned with the Company’s performance targets relating to annual growth of non-GAAP E.P.S. and non-GAAP operating income. The Management Incentive Plan has historically required 15% non-GAAP E.P.S. growth over the prior year for a payout at target and 5% non-GAAP E.P.S. growth for a payout at threshold. In addition, the plan requires a minimum level of operating income of 3% growth over the prior year in order to trigger any payout under the plan. In 2015, threshold performance for both the non-GAAP E.P.S. and operating income measures were met, however the actual non-GAAP E.P.S. growth for 2015 of 7% fell below target performance of 15% growth. The Company’s non-GAAP E.P.S. growth for 2015, as adjusted to remove the negative effects of foreign currency translation, was 18% growth. As a result, the Compensation Committee considered the impact of foreign currency translation on the non-GAAP operating income and non-GAAP E.P.S. results in 2015 and determined it was appropriate to adjust for approximately 50% of the negative impact of foreign currency translation on the non-GAAP E.P.S. growth result. This level of performance, as adjusted by the Compensation Committee, resulted in payouts under the Management Incentive Plan to named executive equal to 84% of their respective incentive payouts at target.

• Long-Term Incentive Plan: The Company continues its long-standing practice of utilizing stock options in order to align the interests of the named executive officers with the Company’s stockholders. On December 9, 2015, the Compensation Committee approved a stock option grant to Mr. O’Connell in the amount set forth in Mr. O’Connell’s Offer Letter with the Company dated June 23, 2015 and described below under Newly Appointed CEO Compensation Arrangement. For Messrs. Cassis and Beaudouin and Ms. Rae, the Compensation Committee approved stock option grants consistent with the annual stock option grants made in prior years. At the time of the annual stock option grant, Mr. Caputo was considering a possible retirement at some point in 2016 and the Compensation Committee decided not to make an annual stock option grant to Mr. Caputo pending the outcome of his retirement considerations. Subsequently, Mr. Caputo decided that he would retire in January 2017.

Compensation Governance and Pay Practices

• The Company adopted a Recoupment Policy for cash incentive awards paid to executives. A full description of the policy can be found below under the heading “Recoupment Policy”.

• The Company implemented stock ownership guidelines for our named executive officers. These guidelines include a share retention requirement in the event a named executive officer fell out of compliance with the stock ownership guidelines. Further details of the guidelines are outlined below under the heading “Equity Ownership Guidelines”.

• The Company implemented a policy against hedging Company equity securities. Further details of the policy can be found below under “Policy on Hedging”.

• The Company does not offer any perquisites for the exclusive benefit of our named executive officers.

• The Company has not made any discretionary or guaranteed bonus payments other than the sign-on award made in conjunction with hiring of Mr. O’Connell (as described below).

• The Company maintains an independent Compensation Committee and an independent Compensation Committee consultant.

2015 Say on Pay Vote

The Compensation Committee values the opinions of our stockholders and considers the outcome of the annual Say on Pay stockholder vote in determining the structure of executive compensation, as well as in making

20

future compensation decisions. Waters received strong stockholder support of our executive compensation programs in 2015 with 94% of voted shares voting in favor of Waters’ executive compensation programs. In part due to this support, we have not made any significant changes to our compensation philosophy or practices and continue to manage our programs in a manner consistent with prior years.

Transition of Mr. Berthiaume

On September 8, 2015, Mr. Berthiaume retired from his position as President and CEO. To assist in the transition of Mr. O’Connell, our new CEO, he remained a non-executive employee until December 31, 2015. In connection with his change in status from executive to non-executive employee, effective October 1, 2015, Mr. Berthiaume’s base salary was reduced to $500,000. He remained eligible to receive his annual bonus with respect to 2015.

Newly Appointed CEO Compensation Arrangement

On June 25, 2015, the Company announced that Mr. O’Connell was hired to serve as the President and CEO of the Company and appointed to be a member of the Board. Mr. O’Connell assumed these positions on September 8, 2015.

In connection with Mr. O’Connell’s hiring, the Company entered into an offer letter (the “Offer Letter”) with him. Pursuant to the terms of the Offer Letter, Mr. O’Connell is entitled to receive an annual base salary of $825,000 and is eligible for an annual bonus based on achievement of performance objectives established by the Compensation Committee in its discretion. The target amount of his annual bonus is 125% of his base salary.

The Offer Letter also provides that, in connection with the commencement of his employment, Mr. O’Connell received the following sign-on awards, which were intended to compensate Mr. O’Connell for a portion of the equity and executive retirement benefits from his prior employer that were forfeited as a result of joining Waters:

• a restricted stock unit award with a grant date value of approximately $2,500,000. The restricted stock unit award vests as to one-third of the award on each of the first three anniversaries of the date of grant, generally subject to continued employment on each vesting date and subject to the other terms and conditions of the Waters Corporation 2012 Equity Incentive Plan (the “2012 Equity Incentive Plan”).

• a non-qualified stock option award having a Black-Scholes value on the grant date of approximately $2,500,000. The non-qualified stock option award vests as to 20% of the shares of common stock underlying the award on each of the first five anniversaries of the date of grant, generally subject to continued employment on each vesting date and subject to the other terms and conditions of the 2012 Equity Incentive Plan.

• a cash payment of $1,700,000 (subject to repayment of a pro rata amount of such payment based on the date of termination of employment if Mr. O’Connell resigns without good reason (as defined in this Offer Letter) or his employment is terminated by the Company for cause (as defined in the Offer Letter) prior to September 8, 2016).

The Offer Letter also provides that Mr. O’Connell will be entitled to reimbursement of certain costs associated with his relocation to the Milford, Massachusetts area pursuant to the Company’s executive relocation program (excluding the allowance for temporary living expenses provided under such program).

Mr. O’Connell was also entitled to receive, as his 2015 equity award at the time annual equity awards were granted to Company executives on December 9, 2015, a non-qualified stock option award having a Black-Scholes value on the date of grant of approximately $5,000,000. The award vests as to 20% of the shares of common stock underlying the award on each of the first five anniversaries of the date of grant, generally subject to continued employment on each vesting date and subject to the other terms and conditions of the 2012 Equity Incentive Plan.

Under his Offer Letter, if Mr. O’Connell’s employment is terminated by the Company other than for cause (as defined in the Offer Letter) or if he resigns for good reason (as defined in the Offer Letter), he will be entitled to receive the severance benefits described in the “Payments upon Termination or Change of Control” section of

21

this Proxy Statement. The Company also has entered into a Change of Control/Severance Agreement with Mr. O’Connell, pursuant to which he will be entitled to certain benefits in connection with a termination without cause (as defined in this agreement) or for good reason (as defined in this agreement), as described in the “Payments upon Termination or Change of Control” section of this Proxy Statement.

The Committee determined Mr. O’Connell’s base salary and target bonus amount, together with the grant date value of the annual grant for 2015 made to him in December, after reviewing the compensation of chief executive officers in our 2015 Industry Peer Group. The elements of Mr. O’Connell’s compensation package were positioned to be aligned with the Company’s executive compensation philosophy, with his base salary set below the market median, total target cash compensation set at approximately the market median and annual long-term incentives in the form of stock options set above the market median. Mr. O’Connell’s base salary of $825,000 approximated the 30^th percentile of the Industry Peer Group market data and, together with his target annual bonus opportunity of 125% of base salary, his total target cash compensation of $1,856,000 was positioned at the 45^th percentile of the Industry Peer Group market data. Mr. O’Connell’s annual stock option grant of $5,000,000, which was made on December 9, 2015, was positioned at the median of the Industry Peer Group market data. These three compensation elements together — base salary, annual incentive and annual stock option grant — resulted in a total target direct compensation that was positioned at the 50^th percentile of the Industry Peer Group market data. As described above, the sign-on restricted stock and stock option awards, together with the sign-on cash payment were intended to compensate Mr. O’Connell for a portion of the equity and executive retirement benefits from his prior employer that were forfeited as a result of joining Waters. The Committee determined Mr. O’Connell’s severance entitlements after reviewing the severance entitlements of chief executive officers of our 2015 Industry Peer Group.

Philosophy and Objectives of Waters Executive Compensation Program

The Waters executive compensation program is intended to be both performance-based and market-based such that a significant portion of compensation is allocated to short and long-term variable performance-based compensation. The objectives of the Company’s executive compensation program are aligned with the Compensation Committee’s philosophy and are as follows:

• To focus senior management on achieving financial and operating objectives that provide long-term stockholder value;

• To align the interests of senior management with the Company’s stockholders; and

• To attract and retain senior executive talent.

The Company’s executive compensation program is designed to motivate and reward executives for sustained high levels of achievement of the Company’s financial and operating objectives. In conjunction with our objective to emphasize performance-based compensation, base salaries are generally targeted below the market median for similarly situated executives in comparable companies. Actual base salaries may vary from this generally targeted position based on the performance, tenure, experience and contributions of the individual executive.

In order to provide target total cash compensation that approximates the median of the market for achieving target performance goals, annual incentive target awards are positioned to be at or slightly above the market median. In the aggregate, these two annual components, base salary and annual incentive, provide a target total cash compensation opportunity that approximates the median of the market for achieving target performance goals. Annual performance targets represent challenging operational and financial goals. Actual incentives will vary with the performance of the Company and the overachievement of performance goals will provide the opportunity for significantly greater reward on an annual basis. Underachievement of threshold performance goals will result in no payout. Actual total cash compensation may be less than or greater than the median of the market, based on these factors. We believe that the structure of our total annual cash compensation effectively aligns executives’ interests with stockholders’ interests by placing emphasis on the achievement of annual financial and operating objectives.

For longer-term alignment, the Company uses stock options to align executive compensation opportunity with stockholder interests because options provide value to the executive only if the Company’s stock price

22

increases over time. The value of Waters’ stock option grants is targeted to be at or above the competitive market and is intended to represent a significant portion of each executive’s total direct compensation. Additionally, stock options increase the orientation of total direct compensation toward performance-based instruments. Waters’ stock options, which vest over a five-year period and have a ten-year term, also serve as a valuable retention tool. The Compensation Committee reviews competitive market data in determining the value of executive stock option grants. In 2015, as described above, the Compensation Committee also granted restricted stock units to Mr. O’Connell in connection with his commencement of employment with us.

Pay Mix

Consistent with this performance-oriented compensation philosophy, performance-based compensation comprises a substantial portion of the target total direct compensation (base salary, target annual incentive award and the grant date value of the long-term incentive award) for our named executive officers. For 2015, the performance-oriented compensation (annual incentive and long-term equity incentives, excluding sign on awards) represented 88% of the target total direct compensation for Mr. O’Connell and 84% for the other named executive officers as a group (other than Mr. Berthiaume). Although it was the intention of the Compensation Committee to grant a stock option to Mr. Berthiaume, he declined to be considered for a stock option award due to his significant ownership position in the Company.

Data Used to Make Compensation Determinations

Competitive Market Assessment

Competitive market data is an important component used in determining the amount of each element of compensation for our named executive officers. The Compensation Committee utilizes Pearl Meyer & Partners to provide advice and analysis on the structure of our executive compensation program as well as competitive data on base salary, total cash compensation and long-term incentives. Pearl Meyer & Partners prepares this competitive assessment annually for the Compensation Committee. The Compensation Committee reviews the total compensation package for each named executive officer from the perspective of total direct compensation, which includes base salary, target annual incentive award and the grant date value of the long-term incentive grant. The Compensation Committee also reviews each named executive officer’s compensation package to ensure that the total compensation package emphasizes performance-based compensation elements and is designed to meet the overall objectives of our executive compensation program. The Compensation Committee considers a range of factors in determining the amount of each compensation element for each named executive officer. The range of factors includes Company performance, individual performance and experience, competitive compensation levels, the competitive market, scope of responsibility and an individual’s potential for making future contributions to the Company.

Pearl Meyer & Partners and the Compensation Committee utilize a core Industry Peer Group of 16 publicly traded companies in the life sciences and analytical instrument industry with generally similar revenues and market capitalization as Waters.

23

The 2015 Industry Peer Group is comprised of the following companies.

Agilent	Mettler-Toledo
C.R. Bard	Pall
Bio-Rad Laboratories	Perkin Elmer
Bruker	ResMed
Edwards Lifesciences	Roper Industries
FLIR Systems	Sigma-Aldrich
Hologic	Teleflex
Illumina	Varian Medical

Each year, Pearl Meyer & Partners evaluates the peer group for its continued appropriateness for external executive compensation comparisons based on the primary selection criteria of similarity in industry, products and services, revenue and market capitalization. In 2015, there were no changes made to the Waters peer group. The target range for both revenue and market capitalization is 50% to 200% of Waters’ revenue and market capitalization. The median revenue for the peer group for the four quarters ending September 2015 was $2,442,000,000 and market capitalization for the peer group as of September 2015 was $7,887,000,000. Waters’ revenue and market capitalization for the same period were $2,040,000,000 and $9,725,000,000 representing the 25th and 54th percentiles, respectively.

Pearl Meyer & Partners and the Compensation Committee also utilized the Aon Hewitt Executive Compensation Survey to review the competitive marketplace for each named executive officer. The Aon Hewitt Executive Compensation Survey provides a general industry perspective based on revenue scope for each named executive officer position. We use the broad survey data in combination with the peer group data in evaluating our named executive officers’ compensation. The Compensation Committee does not rely upon data from any individual company participating in any of these surveys in making compensation decisions. Data from the survey source and the peer companies are combined to develop a primary market composite which is based on an average of survey data and peer company data.

Elements of Executive Compensation

There are three key elements of our executive compensation program: base salary, annual incentive awards, and long-term incentive awards. Each element of executive compensation addresses specific objectives of the program and together they meet the overall philosophy and objectives of our executive compensation program as described above. The mix of short-term cash incentives and long-term equity incentives focuses executives on the achievement of annual financial and operating objectives that drive long-term stockholder value. In addition, the Compensation Committee reviews the combined total of all compensation elements, or total direct compensation, in order to appropriately position total direct compensation relative to both the marketplace and the Company’s objectives. Although the amount of each element of compensation for each named executive officer differs based on position-specific market data, the critical nature of the executive’s position to the business, the executive’s level of contribution and other individual factors, the overall structure and compensation elements utilized are consistent for the CEO and all other named executive officers, other than certain sign-on awards specific to the CEO when he commenced employment with us.

Compensation Element	Objective	Target Position to Market	2015 Actual Position to Market for Named Executive Officers (1)
Base Salary	To attract and retain senior executives and other key employees.	Generally targeted at or below the 50th percentile. Actual individual salaries may vary based on an executive’s performance, tenure, experience and contributions.	The overall market position for base salaries in 2015 was at the 35th percentile of the market. Individual base salaries ranged from below the 25th percentile to the 45th percentile.

24

Compensation Element	Objective	Target Position to Market	2015 Actual Position to Market for Named Executive Officers (1)
Annual Incentive	To motivate named executive officers to achieve strong financial and operational goals as established by the Compensation Committee at the beginning of the fiscal year.	Target payouts at 100% achievement of performance goals are generally positioned at or slightly above the 50th percentile in order to achieve a target total cash position (base plus annual incentive) that approximates the 50th percentile. Achievement of threshold performance goals is required for any payout.	The overall total target cash market position was at the 45th percentile of the market. (Target Total Cash is defined as the sum of base salary and target annual bonus.)
Long-Term Performance Based Awards	To motivate senior executives and other key employees to contribute to the Company’s long-term growth of stockholder value and to align compensation with the growth in Waters stock price. Long-term performance-based awards are also designed to assist in the retention of senior executives and key employees.	Equity compensation is targeted to be at or above the competitive market and to represent a significant portion of the executive’s total direct compensation. Actual individual grants are determined based on the executive’s position, performance, tenure, experience and contributions.	Annual long-term incentive awards and Target Total Direct Compensation respectively approximated the 70th and 65th percentiles of the market. (Target Total Direct Compensation is defined as the sum of Total Target Cash plus the grant date value of the most recent long-term incentive grant.)

(1) The 2015 Compensation Element Results in the above table reflect the analysis completed by Pearl Meyer & Partners in the fourth quarter of 2015. It has been the consistent practice of the Compensation Committee to grant long-term performance equity-based compensation to the named executive officers at the Compensation Committee meeting held in December of each year. This Pearl Meyer & Partners analysis therefore includes the cash compensation comprised of base salary and annual incentive effective as of January 1, 2015 and the annual long-term performance equity award granted on December 11, 2014 to Messrs. Caputo, Cassis and Beaudouin and Ms. Rae. Given that it includes equity granted in December 2014, equity awards granted to Mr. O’Connell in 2015 have not been included.

Base Salary

The base salaries for the named executive officers are reviewed annually by the Compensation Committee. Individual salaries are based upon a combination of factors including past individual performance and experience, Company performance, scope of responsibility and an individual’s potential for making contributions to future Company performance. The Compensation Committee considers all these factors in determining base salary increases and does not assign a specific weighting to any individual factor.

Assessment of 2015 Base Salary

In addition to considering the factors listed above, the Compensation Committee also considers the competitive market position of an executive officer’s base salary. Base salary increases are approved by the Compensation Committee at the end of the fiscal year with an effective date at the beginning of the next fiscal year, or January 1^st of each year. The competitive assessment completed by Pearl Meyer & Partners at the end of 2014

25

provided the market information used in determining the base salary in effect in 2015 for our named executive officers (other than Mr. O’Connell). The overall competitive market position for the executive officers in this Pearl Meyer & Partners analysis was at the 35^th percentile.

Based on (1) an improving economic environment, (2) a Pearl Meyer & Partner market assessment which indicated that base salaries for executives increased on average 5% in 2014 and (3) a base salary competitive position at the 25^th percentile, the Compensation Committee approved a 5% base salary increase for all named executive officers for 2015. In addition, the Compensation Committee approved market adjustment increases for Mr. Cassis and Ms. Rae of 7% and 6%, respectively, in order to position their base salaries at a more competitive position relative to the market and in each case closer to the 25^th percentile of the market data.

Annual Incentive

The Management Incentive Plan is the annual incentive plan for our named executive officers, senior executives, and other key employees of the Company. The Compensation Committee establishes Company performance targets at the beginning of each fiscal year for our named executive officers. A summary of our 2015 Management Incentive Plan payout structure is described in the table below.

Name	2015 Management Incentive Plan Payout Structure as a Percent of Base Salary
	Below Threshold Performance			Threshold Performance	Target Performance			Maximum Performance
Douglas A. Berthiaume (1)		0	%	31.25%		125	%		375	%
Christopher J. O’Connell (2)		0	%	31.25%		125	%		375	%
Arthur G. Caputo		0	%	27.50%		110	%		330	%
Eugene G. Cassis		0	%	18.75%		75	%		225	%
Mark T. Beaudouin		0	%	18.75%		75	%		225	%
Elizabeth B. Rae		0	%	12.50%		50	%		150	%

(1) Mr. Berthiaume’s annual incentive compensation was not prorated for 2015.

(2) Mr. O’Connell’s 2015 annual incentive compensation is prorated based on the number of full and partial months of employment during 2015.

In order to receive an incentive payout equal to 100% of the executive’s target annual bonus, the Company must achieve 100% of its performance target. All payouts at threshold performance are equal to 25% of the named executive officer’s target annual bonus, and are payable upon achievement of both a minimum non-GAAP operating income threshold performance target and a minimum non-GAAP E.P.S. goal. Performance below these minimum threshold levels results in no payout. The maximum payout under the plan is 300% of the target annual bonus for each named executive officer. Payouts are interpolated for performance between threshold, target and maximum levels. The Compensation Committee believes that a maximum payout opportunity of 300% of the target payout is consistent with the philosophy to position total target cash at the median of the competitive market and to provide the opportunity for significantly greater reward for overachievement of challenging performance goals. As discussed in detail below, the Compensation Committee establishes annual performance goals which are intended to be challenging but able to be achieved if Company performance is strong.

The Compensation Committee has consistently utilized non-GAAP E.P.S. as the primary performance measure under the Management Incentive Plan for named executive officers. For the past 20 years, the Compensation Committee has established a goal of 15% non-GAAP E.P.S. growth over the prior year. The Company has exceeded the target of 15% non-GAAP E.P.S. growth in 12 of the past 20 years and has exceeded threshold performance 16 of the past 20 years.

Use of the non-GAAP measure promotes executive team alignment, focuses the executive team on operational efficiencies and profitable growth, provides a long-term perspective among executives and drives long-

26

term stockholder value. In addition to the non-GAAP E.P.S. growth target, the Compensation Committee also requires that a minimum non-GAAP operating income measure be achieved in order to maintain a balanced focus on operational improvements excluding the effects of any benefits from finance costs, taxes and stock repurchases to non-GAAP E.P.S. The non-GAAP E.P.S. growth targets are based on E.P.S. reported in accordance with GAAP, but adjusted to exclude certain charges and credits, net of tax, including but not limited to purchased intangibles amortization, acquisition, restructuring, litigation, lease termination, acquired in-process research and development costs, asset and equity investment impairments, tax audit settlements and adjustments and other items considered unusual or one-time costs. The Company considers these items non-operational and not directly related to ongoing operations and therefore excludes them from the performance metrics set under our annual Management Incentive Plan. The Compensation Committee reviews and approves the annual adjusted non-GAAP E.P.S. for purposes of measuring E.P.S. growth goal achievement.

For 2015, the Compensation Committee retained non-GAAP operating income and non-GAAP E.P.S. as the primary performance metrics under the Management Incentive Plan and also established a non-GAAP operating income goal, the attainment of which would determine the maximum amount of bonus payable to our named executive officers under our Management Incentive Plan, as described below. Such amounts are subject to the Management Incentive Plan’s individual payout limit as described above. The additional non-GAAP operating income goal was established to enhance our ability to deduct amounts paid under the Management Incentive Plan as “performance based compensation” for purposes of Section 162(m) of the Internal Revenue Code. The maximum payout opportunity for Mr. Berthiaume is set at 1% of non-GAAP operating income, and the maximum payout opportunity is set at .5% of non-GAAP operating income for Messrs. Caputo, Cassis, Beaudouin and Ms. Rae, but, in each case, not more than the maximum payment amount included in the Management Incentive Plan. Mr. O’Connell’s bonus was not subject to this additional performance goal due to the fact that he commenced employment with us in the third quarter of 2015.

The performance measures required for payout under the 2015 Management Incentive Plan are outlined in the table below.

2015 Performance Measures	2015 Management Incentive Plan Performance Targets
	Below Threshold Performance			Threshold Performance			Target Performance			Maximum Performance
2015 Non-GAAP E.P.S. growth over 2014		<5	%		5	%		15	%		27.5	%
2015 Non-GAAP Operating Income growth over 2014		<3	%		3	%
Both threshold performance measures must be met in order for a payout under the Plan. Once threshold non-GAAP operating income performance and non-GAAP E.P.S. performance has been achieved, increasing levels of payout are based on non-GAAP E.P.S growth only.

In fiscal year 2015, non-GAAP operating income was $592,823,000 which generated a maximum aggregate payout opportunity of $17,784,690 under the Management Incentive Plan. Non-GAAP operating income for 2015 represents a 5.5% increase over 2014. Non-GAAP E.P.S. for 2015 was $5.89, which represents 7% growth over 2014 non-GAAP E.P.S. of $5.48. Not taking into account the negative impact of foreign currency translation, non-GAAP E.P.S. growth over 2014 would have been 18%. Non-GAAP E.P.S. and non-GAAP operating income for 2015 and 2014 excluded, net of tax, as applicable, purchased intangibles amortization, infrequent income tax items, litigation provisions, restructuring costs and acquired in-process research and development costs from its non-GAAP adjusted amounts since the Company believes that these items are not directly related to ongoing operations. Utilizing its ability to apply negative discretion to the maximum payout opportunity, the Compensation Committee considered the significant impact of foreign currency translation on the 2015 non-GAAP operating income and non-GAAP E.P.S. results and determined that it was appropriate to adjust for approximately 50% of the 2015 negative impact of foreign currency translation on the non-GAAP E.P.S. growth result. This performance resulted in payouts under the Management Incentive Plan to our named executive officers equal to 84% of their respective incentive payouts at target. Without this adjustment the payouts under the Management Incentive Plan would have been equal to 44% of target.

27

The Company periodically reviews the Management Incentive Plan with Pearl Meyer & Partners. The objectives of this review are to consider the alignment of the Management Incentive Plan with Waters’ compensation philosophy and emphasis on pay-for-performance and to review the performance measures utilized under the plan to ensure these measures provide the best ongoing assessment of strategy execution and the creation of stockholder value.

Long-Term Performance-Based Awards

The Compensation Committee considers long-term performance-based awards in the form of equity-based compensation at the Compensation Committee’s annual December meeting. Multiple factors, considered collectively, are reviewed by the Compensation Committee in determining the number of shares to award each named executive officer. These factors include competitive market data, dilution, share usage, stock compensation expense, the financial and operational performance of the Company, each named executive officer’s individual performance, and the prior number of shares granted both individually to each named executive officer and in aggregate to all named executive officers.

It has been the long-standing practice of the Compensation Committee to utilize non-qualified stock options to align the interests of our named executive officers and other senior executives with those of Waters’ stockholders. We believe that stock options provide strong alignment between stockholders and these executives because the value of a stock option to an executive is directly related to the stock price appreciation delivered to stockholders over time. Conversely, poor stock price performance provides no stock option value to the executive.

Competitive market data for long-term performance-based awards is prepared for the Compensation Committee by Pearl Meyer & Partners. As noted above, the Compensation Committee uses this data as one of the factors in determining the size of the equity grant for each named executive officer. Consistent with the Compensation Committee’s philosophy of emphasizing performance-based pay, the Compensation Committee targets long-term incentives above the median of the competitive market data for each named executive officer. The Compensation Committee targets long-term incentives above the market median because, in combination with a base salary target below the market median and an annual incentive target at or slightly above the market median, it achieves the Compensation Committee’s objective of emphasizing performance-based compensation. In addition, unlike most of the Company’s peer group that grants a mix of long-term incentive instruments including time-based restricted stock, the Compensation Committee has historically granted 100% stock options. The only exceptions to the use of 100% stock options in the annual equity grant was a one-time retention RSU grant made in December 2013 in conjunction with the announced CEO transition and a sign-on RSU grant to Mr. O’Connell. Pearl Meyer & Partners prepares long-term incentive guidelines for the Compensation Committee that derive a range at the 50^th and 75^th percentiles of the competitive market data for long-term incentives of the Industry Peer Group. The value of the annual grant comprised of non-qualified stock options granted to Messrs. O’Connell, Cassis, Beaudouin and Ms. Rae on December 9, 2015 were all within the long-term incentive guidelines as prepared by Pearl Meyer & Partners. As mentioned previously, a stock option award was not made to Mr. Caputo due to discussions regarding a potential retirement by Mr. Caputo. Mr. Caputo subsequently decided that he would retire in January 2017. The non-qualified stock options were granted under the 2012 Equity Incentive Plan and will vest 20% per year for five years. The non-qualified stock options have an exercise price equal to the closing price of Waters’ common stock on the grant date and have a ten-year term.

In addition, as described above, Mr. O’Connell received a grant of stock options and restricted stock units in connection with his commencement of employment with the Company. These awards were intended to compensate Mr. O’Connell for a portion of the loss of equity and supplemental executive retirement benefits from his prior employer as a result of joining Waters. The restricted stock units granted to him were intended to encourage his continued service with us through the use of a three-year vesting schedule. The stock options granted to him were intended to both encourage his retention as well as to align his compensation with the performance of our stock and his interests with those of our stockholders. These stock options vest 20% per year for five years, generally subject to his continued employment with Waters.

A review of share usage, dilution and stock based compensation expense was also prepared by Pearl Meyer & Partners with data as of the fiscal year ended December 31, 2014. In this analysis the Company’s

28

annual share usage, as a percent of common shares outstanding, approximates the median of the Industry Peer Group on both a one and three year basis. The Company’s dilution was 4.6% which falls between the median and 75^th percentile of the Industry Peer Group. The Company’s fair market value of annual stock-based compensation for the fiscal year ended December 31, 2014 also approximated the 50^th percentile and as a percent of market capitalization was below the 25^th percentile. The Compensation Committee reviews these metrics annually and in December 2015 determined that the overall grant practices with respect to share usage and stock compensation expense were appropriate relative to the Industry Peer Group.

The Compensation Committee also believes that it is important to provide meaningful reward and recognition opportunities to the named executive officers irrespective of the potential gains they may realize from prior long-term performance based awards. The Compensation Committee believes that the stock option grants made to the named executive officers in December 2015 were aligned with the Company’s philosophy of emphasizing long-term performance-based awards and were consistent with the scope and level of contribution for each of our named executive officers.

Perquisites and Benefits

The Company does not offer any perquisites for the exclusive benefit of executive officers. Mr. O’Connell was, however, entitled to relocation benefits in connection with his move to Massachusetts.

The named executive officers are eligible to participate in compensation and benefit plans that are generally offered to other employees, such as the Waters Employee Investment Plan (the “401(k) Plan”), the Employee Stock Purchase Plan and health and insurance plans. They are also eligible to participate in the Waters 401(k) Restoration Plan (the “401(k) Restoration Plan”) that is available to all employees who meet certain minimum earnings eligibility criteria. The Waters 401(k) Restoration Plan and the Waters Retirement Restoration Plan are designed to restore the benefits, matching contributions and compensation deferral that are limited by Internal Revenue Service benefit and compensation maximums. These plans are described more fully in the narrative that accompanies the Pension Benefits table and the Non-Qualified Deferred Compensation table in this Proxy Statement.

Severance and Change of Control Arrangements

The Company provides severance protection to each of Messrs. O’Connell, Berthiaume, Caputo, Cassis and Beaudouin and Ms. Rae pursuant to a Change of Control/Severance Agreement in the event that he or she is terminated or resigns for good reason prior to or following a change of control. Our severance and change in control protections are designed to ensure continuity of executive management in the event of a change of control of the Company, and to ensure the ability of executives to evaluate a potential change of control in the best interests of the Company and stockholders. For a description of the severance and change in control protections in our named executive officers’ Change of Control/Severance Agreements, please see the “Payments Upon Termination or Change of Control” section of this Proxy Statement.

The Company also provides Mr. O’Connell certain severance protections pursuant to his Offer Letter in the event his employment is terminated by the Company other than for cause (as defined in the Offer Letter) or if he resigns for good reason (as defined in the Offer Letter) outside of the change of control context, as described below in the “Payments Upon Termination or Change of Control” section of this Proxy Statement.

Equity Ownership Guidelines

The importance of ownership in Waters stock by its named executive officers is emphasized through ownership guidelines that require the CEO to acquire and retain common stock equal to five times his base salary over a three-year period. Other named executive officers are required to acquire and retain common stock equal to two times their base salary over a five-year period. If a named executive officer does not achieve these ownership guidelines within the applicable three or five-year period, a disposition guideline will be applied. The disposition guideline requires that, upon subsequent exercise of a stock option, 50% of the named executive officer’s net after-tax profit from such exercise be retained in shares of Waters common stock until the stock ownership guideline is achieved. A named executive officer who subsequently falls out of compliance will have 12 months to regain compliance before the disposition guideline on stock option exercises is applied. Vested “in-the-

29

money” stock options and restricted stock count toward determining compliance for the purpose of accumulating shares to comply with the stock ownership guidelines. The ownership guidelines have been met by Messrs. Berthiaume, Cassis, Caputo, Beaudouin and Ms. Rae. Mr. O’Connell is in the process of meeting the requirements set forth in the ownership guidelines.

Recoupment Policy

The Company has adopted a Recoupment Policy for cash incentive awards paid to current or former named executive officers under the Company’s management incentive plans. Under this policy, if any executive officer engaged in misconduct that resulted in a restatement of financial results, the Board or an authorized committee, such as the Compensation Committee, if it is determined appropriate, could seek reimbursement of the portion of management incentive plan awards impacted by the event. The Company will review and as necessary amend or replace the Recoupment Policy to be in full compliance with the Dodd-Frank Act when rules are adopted with respect to the Dodd-Frank Act’s recoupment parameters.

Tax and Accounting Implications

Waters considers the tax and accounting aspects of the elements of compensation utilized by the Company in determining the most effective method to use to deliver executive compensation. This includes, but is not limited to, Section 162(m) of the Internal Revenue Code and the regulations thereunder (collectively, “Section 162(m)”). Section 162(m) generally limits the tax deduction available to public companies for annual compensation paid to the chief executive officer and next three highest paid officers (exclusive of the chief financial officer) in excess of $1 million unless the compensation qualifies as performance-based. The Compensation Committee intends for payments under the Management Incentive Plan and stock option grants under the 2003 Equity Incentive Plan and 2012 Equity Incentive Plan to qualify as performance-based compensation under Section 162(m). It is the Company’s intent to qualify plans for full deductibility to the extent that it is consistent with the Company’s overall compensation objectives; however, the Compensation Committee retains complete discretion to make (and has made) payments to named executive officers that would not qualify as performance-based compensation to the extent necessary and appropriate to support the Company’s strategies and long-term success.

(a) Mr. O’Connell is not eligible to participate in The Waters Retirement Plan and Retirement Restoration Plan because such plans were frozen in 2007.

(b) The Waters Retirement Plan and Retirement Restoration Plan were frozen in 2007.

The present value of the accumulated benefit is calculated in accordance with FASB Accounting Standards Codification Topic 715 Compensation — Retirement Benefits. The Company’s policy and assumptions made in connection with the valuation of this accumulated benefit are disclosed in the footnotes to the Waters 2015 Annual Report on Form 10-K for the fiscal year ended December 31, 2015, which are incorporated herein by reference.

The Waters Retirement Plan (“Retirement Plan”) is a U.S. defined benefit cash balance plan for eligible U.S. employees. The Waters Retirement Restoration Plan (“Retirement Restoration Plan”) is a U.S. unfunded, non-qualified plan which provides supplemental retirement benefits out of the general assets of the Company that are otherwise limited due to regulations promulgated by the Internal Revenue Service limiting the amount of compensation that may be taken into account in computing the benefit payable under the Retirement Plan. Each participant’s benefits under the Retirement Plan and Retirement Restoration Plan are determined based on annual pay credits and interest credits which are made to each participant’s notional accounts. Effective December 31, 2007, future pay credits to the Retirement Plan and Retirement Restoration Plan on behalf of senior executives were discontinued and no further pay credits will be made on or after January 1, 2008. Interest credits will continue to be made to participant’s notional accounts. Interest credits are based on the one-year constant maturity Treasury Bill rate on the first business day in November of the preceding plan year plus 0.5%, subject to a 5.0% minimum and a 10.0% maximum rate.

36

A participant becomes vested in his or her notional accounts under the Retirement Plan and Retirement Restoration Plan upon completion of five years of service, at which time the participant becomes 100% vested. The normal retirement age under the plans is age 65. Messrs. Berthiaume and Caputo are currently eligible for early retirement under the Retirement Plan and Retirement Restoration Plan. Under these plans, early retirement is defined as attainment of age 62 with at least 10 years of service. However, former participants of the Millipore Retirement Plan (a former parent company of Waters) are eligible for early retirement upon attainment of age 55 with at least 10 years of service. Messrs. Berthiaume, Caputo, and Cassis are former Millipore Retirement Plan participants and are eligible for retirement.

The valuation method and material assumptions used in calculating the benefits reported in column (d) are disclosed in the Waters 2015 Annual Report for the fiscal year ended December 31, 2015, and are incorporated herein by reference.

The table below summarizes the nonqualified deferred compensation in the last fiscal year for our named executive officers.

Berthiaume, Caputo, Cassis and Beaudouin and Ms. Rae: $1,663,828, $241,286, $365,404, $678,602 and $216,871, respectively.

All nonqualified deferred compensation contributions made by the named executive officer, or by the Company on behalf of the named executive officer, are made pursuant to the 401(k) Restoration Plan. The purpose of the 401(k) Restoration Plan is to allow certain management and highly compensated employees to defer salary, commissions and Management Incentive Plan payments to a non-qualified retirement plan in addition to the amount permitted to be deferred under the 401(k) Plan ($18,000 in 2015, or $24,000 if age 50 or older). The 401(k) Restoration Plan is also intended to permit participants to receive the additional matching contributions that they would have been eligible to receive under the 401(k) Plan if the Internal Revenue Service limit on compensation for such plan ($265,000 in 2015) did not apply. Upon termination or retirement from the Company, account balances are distributed according to the payment option and form of payment elected by the participant at time of deferral. Payments of account balances may be in the year of termination or the year of termination plus one full year and the form of payment and may be made in either a lump sum or installments.

Payments Upon Termination or Change of Control

Under his Offer Letter, if Mr. O’Connell’s employment is terminated by the Company other than for cause (as defined in the Offer Letter) or if he resigns for good reason (as defined in the Offer Letter), Mr. O’Connell will be entitled to, subject to the execution of a release of claims and continued compliance with the restrictive covenants contained in the Offer Letter, continued salary and target annual bonus for a period of twenty-four (24) months. In addition, Mr. O’Connell will be entitled to receive a lump sum payment equal to the amount that the Company would have paid in premiums under the life, accident, health and dental insurance plans in which Mr. O’Connell and his dependents were participating immediately prior to the termination of his employment for the twenty-four (24) -month period following the date of termination. If Mr. O’Connell is employed on or after July 1 of the year in which his employment termination occurs, he will also be entitled to a pro-rata annual bonus for such year, based on actual performance. Mr. O’Connell will be subject to non-competition and non-solicitation restrictions for a period of two years following the termination of his employment.

Messrs. Berthiaume, Caputo, Cassis, and Beaudouin and Ms. Rae do not have employment agreements with the Company. However, each is party to an Executive Change of Control/Severance Agreement dated February 24, 2004 and amended February 27, 2008. Under the terms of their agreements, as amended, if any such executive’s employment is terminated without cause (as defined in the agreement) during the period beginning 9 months prior to, and ending 18 months following, a “change of control” of the Company (as defined in the agreement), or such executive terminates his or her employment for good reason (as defined in the agreement) during the 18 month period following a change of control of the Company, such executive would be entitled to receive the following amounts in a lump sum payment:

• Two times annual base salary;

• Two times the greater of the annual accrued incentive plan payment in the year of termination or the target incentive plan payout; and

• Twenty-four months of continued insurance benefit coverage (life, accident, health and dental) substantially similar to the coverage he or she had been receiving prior to any such termination, or the premium equivalent.

In addition, the Company entered into a Change of Control/Severance Agreement with Mr. O’Connell dated September 8, 2015. Under the terms of his agreement, if Mr. O’Connell’s employment is terminated without cause (as defined in the agreement) or he resigns for good reason (as defined in the agreement) during the period beginning 9 months prior to, and ending 18 months following, a “change of control” of the Company (as defined in the agreement), he would be entitled to receive the following amounts in a lump sum payment:

• Three times annual base salary;

• Three times the greater of the annual accrued incentive plan payment in the year of termination or the target incentive plan payout; and

• Thirty-six months of continued insurance benefit coverage (life, accident, health and dental) substantially similar to the coverage he or she had been receiving prior to any such termination, or the premium equivalent.

The foregoing amounts payable under the agreement are to be reduced by the amount of any severance or similar amounts paid or payable under Mr. O’Connell’s Offer Letter, as described above.

For purposes of these agreements, “change of control” generally refers to the closing of a merger, consolidation, liquidation or reorganization of the Company after which the Company does not represent more than 50% of the resulting entity; the acquisition of more than 50% of the voting stock of the Company; or the sale of substantially all of the Company’s assets.

The agreements with Messrs. Berthiaume, Caputo, Cassis, and Beaudouin and Ms. Rae further provide that the benefits will be supplemented by an additional payment to “gross up” the executive for any excise tax under the “golden parachute” excise tax provisions of Sections 280G and 4999 of the Internal Revenue Code of 1986, as amended (a “280G Excise Tax”) to ensure that after the payments for change of control, the executive is in the

38

same economic position as if the payment were not subject to an excise tax. This additional payment would be equal to the sum of the excise tax on any “parachute payment” and the additional tax attributable to the receipt of the gross-up payment. While these existing agreements contain a 280G Excise Tax gross-up provision, no agreements executed after February 27, 2008 contain such a provision. The agreement with Mr. O’Connell provides that, in the event that he is subject to a 280G Excise Tax, he will be entitled to the greater of the following amounts, determined on an after-tax basis: (1) all payments that are or would be covered by Section 280G (the “Transaction Payments”), or (2) a portion of such Transaction Payments so as to provide Mr. O’Connell with the largest payment possible without the imposition of a 280G Excise Tax.

In addition, for Messrs. Berthiaume, Caputo, Cassis, and Beaudouin and Ms. Rae, in the event of a change of control, all of their outstanding and unvested stock options and restricted stock units will fully accelerate and become fully exercisable. For Mr. O’Connell, in the event of a termination of employment without cause or resignation for good reason, in each case, within 9 months prior or 18 months following a change of control, all of his outstanding and unvested stock options and restricted stock units will fully accelerate and become fully exercisable. In addition, if Mr. O’Connell’s employment is terminated as a result of his death or disability or is terminated by us without cause or by him for good reason, his sign-on options and restricted stock units granted in 2015 will vest in full.

If the employment of our named executive officers had been terminated without cause or any officer resigned for good reason on December 31, 2015 and within 18 months of a change of control, they would have received the following cash severance and benefits based on the price per share as of December 31, 2015. Mr. Berthiaume’s employment terminated on December 31, 2015. He did not receive any severance payments or benefits in connection with his retirement on this date.

Potential Payments Upon Termination Following a Change of Control
Name	Cash Severance		Other Benefits				Total Value of Change- in-Control Related Benefits
	Base Salary	Incentive Plan	Benefits Continuation	In-the- Money Value of Accelerated Stock Options	Value of Accelerated Restricted Stock Units	Excise Tax Gross-Up
Christopher J. O’Connell	$2,475,000	$959,063	$61,260	$1,624,544	$2,723,092	n/a	$7,842,959
Douglas A. Berthiaume	$1,000,000	$2,092,802	$40,046	—	—	—	$3,132,848
Arthur G. Caputo	$1,066,902	$1,173,593	$28,985	$6,123,270	$1,484,148	—	$9,876,898
Eugene G. Cassis	$787,500	$590,625	$28,459	$1,898,124	$555,008	$915,375	$4,775,091
Mark T. Beaudouin	$841,384	$631,038	$40,679	$2,941,318	$813,940	—	$5,268,359
Elizabeth B. Rae	$546,000	$273,000	$39,373	$2,397,608	$588,653	—	$3,844,634

The cash severance was calculated assuming the base salary and annual incentive plan target under the Management Incentive Plan for 2015, in effect on December 31, 2015. The benefit continuation payment is based on premium costs as of December 31, 2015. Mr. Berthiaume’s base salary reflects his part-time salary in effect on December 31, 2015. Amounts in respect of stock options were determined by multiplying the number of stock options that would have vested upon such employment termination or change in control, as applicable, by the difference between $134.58, the closing price of Waters common stock on December 31, 2015, and the applicable exercise prices of such stock options. Amounts in respect of restricted stock units were determined by multiplying the number of restricted stock units that would have vested upon such employment termination or change in control, as applicable, by $134.58, the closing price of Waters common stock on December 31, 2015.

Director Compensation

The table below summarizes the director compensation for the Company’s non-employee directors in the last fiscal year. Neither Mr. O’Connell nor Mr. Berthiaume received any compensation for their service as a director during 2015. The compensation they received in respect of their employment is included in the Summary Compensation Table above.

Director Compensation Fiscal Year 2015
Name	Fees Earned or Paid in Cash ($)	Stock Awards ($)	Option Awards ($)	Total ($)
	(a)	(b)	(c)
Joshua Bekenstein	$71,500	$136,656	$107,760	$315,916
Michael J. Berendt, Ph.D.	$98,000	$136,656	$107,760	$342,416
Edward Conard	$79,000	$136,656	$107,760	$323,416
Laurie H. Glimcher, M.D.	$65,500	$136,656	$107,760	$309,916
Christopher A. Kuebler	$91,000	$136,656	$107,760	$335,416
William J. Miller	$104,000	$136,656	$107,760	$348,416
JoAnn A. Reed	$77,500	$136,656	$107,760	$321,916
Thomas P. Salice	$144,000	$136,656	$107,760	$388,416

(a) Reflects Board and committee retainers and meeting fees earned in 2015. For Messrs. Berendt, Kuebler, Miller and Salice, these amounts include the meeting fees paid in conjunction with their participation on the Succession Planning Committee.

(b) Messrs. Bekenstein, Berendt, Conard, Kuebler, Miller and Salice, and Mss. Glimcher and Reed were each granted 1,200 shares of restricted stock on January 2, 2015, with a grant date fair value of $113.88 per share (which reflects the closing price of the Company’s common stock on the date of grant) and a vesting date of January 4, 2016. These shares were outstanding as of December 31, 2015.

(c) Our non-employee directors were each granted 4,000 non-qualified stock options on January 2, 2015, with an exercise price of $113.88 (which was the closing price of the Company’s common stock on the date of grant), and a vesting date of January 4, 2016. The amount set forth in this column reflects the aggregate grant date fair value of non-qualified stock options, computed in accordance with FASB ASC Topic 718, disregarding the effect of estimated forfeitures. The assumptions used to calculate these amounts are disclosed in the footnotes to the Waters Annual Reports on Form 10-K for the fiscal year ended December 31, 2015, which are incorporated herein by reference. The outstanding stock options held by Messrs. Bekenstein, Berendt, Conard, Kuebler, Miller and Salice, and Mss. Glimcher and Reed on December 31, 2015, were 35,000, 35,000, 35,000, 35,000, 31,000, 35,000, 16,800 and 39,000 options, respectively.

For 2015, each non-employee director was paid a retainer of $55,000 for the year, paid in quarterly installments, and a $1,500 fee for each Board and committee meeting attended. The additional annual retainer for the lead director for 2015 was increased to $20,000 (from $15,000 in 2014) resulting in a total annual retainer for the lead director of $75,000. This increase in retainer was based on the competitive assessment completed by Pearl Meyer & Partners for 2015 and was intended to align director compensation practices with that of the Industry Peer Group. In addition, for the same reasons, the annual retainers for 2015 for the chairs of the Compensation Committee and the Nominating and Corporate Governance Committee were increased to $10,000 (from $7,500 in 2014), resulting in a total annual retainer for the chairs of each such committee to $65,000. There were no changes to the annual Board retainer, the Audit Committee Chair retainer or meeting fees for 2015. Consistent with past practice, equity compensation was granted to directors on the first business day of the fiscal year and each director received 4,000 non-qualified stock options and 1,200 shares of restricted stock on January 2, 2015. The exercise price of the stock option grant was equal to the closing price on the grant date.

40

All directors are also reimbursed for expenses incurred in connection with their attendance at meetings. Directors who are full-time employees of the Company receive no additional compensation or benefits for service on the Board or its committees.

The Compensation Committee utilizes Pearl Meyer & Partners to provide advice on the structure of director compensation. Pearl Meyer & Partners and the Compensation Committee utilize sources of data consistent with the executive compensation assessment which include the Industry Peer Group of 16 publicly traded companies described above in the Compensation Discussion and Analysis. Based on the competitive assessment conducted by Pearl Meyer & Partners, cash compensation for directors in 2016 will remain consistent with 2015; however the equity compensation grant to directors will be reduced to a total value of $220,000. Beginning with the director equity grants on the first business day in January 2016, the Company will grant a total of $220,000 in equity value to directors, with 50% of the value in the form of restricted stock and 50% in the form of non-qualified stock options. The number of non-qualified stock options will be determined based on the Black-Scholes value on the date of grant. Both the restricted stock and non-qualified stock option grants to directors have a one-year vesting provision. In addition, the restricted stock and non-qualified stock option grant agreements provide for acceleration of any unvested amounts upon the death of a director. Consistent with the annual total retainer for the lead director, the annual total retainer for the non-executive chair was established at $75,000.

The Company also sponsors the 1996 Non-Employee Director Deferred Compensation Plan, which provides non-employee members of the Board with the opportunity to defer 100% of retainer, meeting and committee fees. Fees may be deferred in cash or invested in Company common stock units. If a director elects to defer his or her fees in Company common stock units, the amount deferred is converted into common stock units by dividing the amount of fees payable by the average stock price of the Company’s common stock for the fiscal quarter. Fees deferred in cash are credited with an interest rate equal to the lesser of the Prime Rate plus 50 basis points or the maximum rate of interest that may be used without being treated as an “above market” interest rate under the SEC guidelines. In 2015, Messrs. Bekenstein, Conard and Kuebler elected to defer fees into Company common stock units and Ms.  Glimcher elected to defer her fees into cash.

Federal securities laws require the Company’s Directors, executive officers, and persons who own more than 10% of the common stock of Waters to file with the SEC, the New York Stock Exchange and the Secretary of the Company initial reports of beneficial ownership and reports of changes in beneficial ownership of the common stock.

To the Company’s knowledge, based solely on review of the copies of such reports and written representations furnished to the Company that no other reports were required, none of the Company’s executive officers, Directors and greater-than-ten-percent beneficial owners failed to file any such report required by Section 16 of the Exchange Act on a timely basis during the fiscal year ended December 31, 2015.
