PROXY STATEMENT



For the 2011 Annual Meeting of Stockholders
to be held on Tuesday, June 14, 2011

        This proxy statement and the enclosed proxy card are being furnished in connection with the solicitation of proxies by the board of directors of Momenta Pharmaceuticals, Inc., also referred to in this proxy statement as the "Company", "Momenta", "we" or "us", for use at the 2011 Annual Meeting of Stockholders, or the Annual Meeting, to be held on Tuesday, June 14, 2011 at 10:30 a.m., local time, at the offices of WilmerHale, 60 State Street, Boston, Massachusetts 02109, and at any adjournment thereof. You may obtain directions to the location of the Annual Meeting by contacting Bruce A. Leicher, Secretary, Momenta Pharmaceuticals, Inc., 675 West Kendall Street, Cambridge, Massachusetts 02142, telephone: (617) 491-9700.

        All proxies will be voted in accordance with the instructions contained in those proxies. If no choice is specified, the proxies will be voted in accordance with the board of directors' recommendations. This means that the proxies will be voted in favor of Proposals 1, 2 and 3 as set forth in the accompanying Notice of Meeting and in favor of annual advisory votes on executive compensation in the case of Proposal 4. Any proxy may be revoked by a stockholder at any time before it is exercised by delivery of written revocation to our Secretary, by executing and delivering a later-dated proxy or by appearing at the Annual Meeting and voting in person.

        Our 2010 Annual Report to Stockholders for the fiscal year ended December 31, 2010 is being mailed to stockholders with the mailing of these proxy materials on or about May 11, 2011.

Important Notice Regarding the Availability of Proxy Materials for the Annual
Meeting of Stockholders to be Held on June 14, 2011:

         This proxy statement and the 2010 Annual Report to Stockholders are available for viewing, printing and downloading at http://ir.momentapharma.com/annuals.cfm.

         A copy of our Annual Report on Form 10-K for the fiscal year ended December 31, 2010 as filed with the Securities and Exchange Commission, except for exhibits, will be furnished without charge to any stockholder upon request to Momenta Pharmaceuticals, Inc., 675 West Kendall Street, Cambridge, Massachusetts 02142, Attention: Bruce A. Leicher, facsimile: (617) 621-0431, by calling (617) 491-9700 or on the web at http://ir.momentapharma.com/annuals.cfm .

Voting Securities and Votes Required

        Stockholders of record at the close of business on Monday, April 18, 2011 will be entitled to notice of, and to vote at, the Annual Meeting. On that date, 50,836,569 shares of our common stock were issued and outstanding. Each share of common stock entitles the holder thereof to one vote with respect to all matters submitted to stockholders at the Annual Meeting. We have no other securities entitled to vote at the Annual Meeting.

        The presence in person or representation by proxy of the holders of a majority of the shares of common stock issued and outstanding and entitled to vote at the Annual Meeting is necessary to establish a quorum for the transaction of business. If a quorum is not present, the Annual Meeting will be adjourned until a quorum is obtained.


        Directors are elected by a plurality of the votes cast by the stockholders (Proposal 1). The ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm (Proposal 2), the approval of the non-binding "say on pay" advisory vote on executive compensation (Proposal 3) and the approval of the non-binding "say on frequency" advisory vote on the frequency of future non-binding "say on pay" advisory votes (Proposal 4) require a majority of the votes cast by holders of stock present or represented and voting on such matter. With respect to Proposal 4, if none of the three frequency options receives the vote of the holders of a majority of the votes cast, we will consider the frequency option (one year, two years or three years) receiving the highest number of votes cast by stockholders to be the frequency that has been recommended by stockholders. However, as described in more detail in Proposal 4, because this proposal is non-binding, our board of directors may decide that it is in the best interest of us and our stockholders to hold future executive compensation advisory votes more or less frequently. The votes will be counted, tabulated and certified by a representative of Broadridge Financial Solutions, who will serve as the inspector of elections at the Annual Meeting.

        Abstentions and broker non-votes (when shares are represented at the Annual Meeting by a proxy specifically conferring only limited authority to vote on certain matters and no authority to vote on other matters) are included in the shares present or represented at the Annual Meeting for purposes of determining whether a quorum is present. Abstentions and broker non-votes will not be considered votes properly cast at the Annual Meeting. Because the approval of each proposal is based on the votes properly cast at the Annual Meeting, abstentions and broker non-votes will not be included in the calculation of the shareholder vote on proposals.

Voting Your Shares

        If you are the record holder of your shares, you may vote in one of four ways. You may vote by submitting your proxy over the Internet, by telephone, or by mail or you may vote in person at the Annual Meeting.

        You may vote over the Internet.     If you have Internet access, you may vote your shares from any location in the world by following the "Vote by Internet" instructions set forth on the enclosed proxy card.

        You may vote by telephone.     You may vote your shares by following the "Vote by Phone" instructions set forth on the enclosed proxy card.

        You may vote by mail.     You may vote by completing, dating and signing the proxy card that accompanies this proxy statement and promptly mailing it in the enclosed postage-prepaid envelope. You do not need to put a stamp on the enclosed envelope if you mail it in the United States. The shares you own will be voted according to the instructions on the proxy card you mail. If you return the proxy card, but do not give any instructions on a particular matter described in this proxy statement, the shares you own will be voted in accordance with the recommendations of our board of directors. Our board of directors recommends that you vote FOR each nominee for director, FOR the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm, FOR the approval of executive compensation, and FOR holding annual non-binding advisory votes on the approval of executive compensation.

        You may vote in person.     If you attend the Annual Meeting, you may vote by delivering your completed proxy card in person or you may vote by completing a ballot. Ballots will be available at the meeting.

Changing Your Vote; Revocation of Proxy; Broker Non-Votes

        Voting over the Internet or by telephone or execution of a proxy will not in any way affect a stockholder's right to attend the Annual Meeting and vote in person. A proxy may be revoked before it is used to cast a vote. To revoke a proxy, a stockholder must:

        Any written notice of revocation or subsequent proxy should be sent to us at the following address: Momenta Pharmaceuticals, Inc., 675 West Kendall Street, Cambridge, MA 02142, Attention: Bruce A. Leicher, Secretary. The shares represented by all properly executed proxies received in time for the Annual Meeting will be voted as specified in those proxies. If the shares you own are held in your name and you do not specify in the proxy card how your shares are to be voted, they will be voted in favor of the election of the directors named in this proxy statement, in favor of the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm, in favor of the approval of our executive compensation, in favor of holding annual non-binding advisory votes on the approval of our executive compensation and, in the discretion of the persons appointed as proxies, on any other items that may properly come before the Annual Meeting. If the shares you own are held in "street name," the bank or brokerage firm, as the record holder of your shares, is required to vote your shares in accordance with your instructions. To vote your shares held in "street name," you will need to follow the directions provided to you by your bank or brokerage firm.

        Under applicable stock exchange rules, if you do not give instruction to your bank, broker or other nominee, the nominee will still be able to vote your shares with respect to certain "discretionary" items, but will not be allowed to vote your shares with respect to certain "non-discretionary" items. In the case of non-discretionary items, the shares that do not receive voting instructions will be treated as broker non-votes. The election of directors, the approval of a non-binding advisory vote on executive compensation and the holding of a non-binding advisory vote on the frequency of future non-binding advisory votes on executive compensation are non-discretionary items and the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm is a discretionary item.

PROPOSAL ONE

ELECTION OF DIRECTORS

Board Recommendation

         The board of directors recommends a vote "FOR" the election of each of Mr. Bruce Downey, Ms. Marsha H. Fanucci and Mr. Peter Barton Hutt as Class I directors.

        We have three classes of directors, currently consisting of three Class I directors, three Class II directors and three Class III directors. At each annual meeting, directors are elected for a full term of three years to succeed those whose terms are expiring. The terms of the three classes are staggered in a manner so that only one class is elected by stockholders annually. Mr. Bruce Downey, Ms. Marsha H. Fanucci and Mr. Peter Barton Hutt are currently serving as Class I directors. The Class I directors elected this year will serve as members of our board of directors until the 2014 annual meeting of stockholders, or until their respective successors are elected and qualified.

        The persons named in the enclosed proxy card will vote to elect Mr. Downey, Ms. Fanucci and Mr. Hutt as Class I directors unless you withhold authority to vote for the election of any or all nominees by marking the proxy card (whether executed by you or through the Internet or telephonic voting). Stockholders may vote by proxy to elect no more than three persons to our board of directors at the Annual Meeting. Mr. Downey, Ms. Fanucci and Mr. Hutt currently serve on our board of directors. The nominees have indicated their willingness to continue to serve if elected. However, if any director nominee should be unable to serve, the shares of common stock represented by proxies may be voted for a substitute nominee designated by our board of directors. Our board of directors has no reason to believe that the nominees will be unable to serve if elected.

        No director or executive officer is related by blood, marriage or adoption to any other director or executive officer. No arrangements or understandings exist between any director or person nominated for election as a director and any other person pursuant to whom such person is to be selected as a director or nominee for election as a director.

CORPORATE GOVERNANCE

General

        We believe that good corporate governance is important to ensure that Momenta is managed for the long-term benefit of our stockholders. We continuously review our corporate governance policies and practices and to compare them to those suggested by various authorities in corporate governance and the practices of other public companies.

        This section describes key corporate governance practices that we have adopted. Complete copies of our corporate governance guidelines, committee charters and code of conduct described below are available on the "Investors—Corporate Governance" section of our website at www.momentapharma.com . Alternatively, you may request a copy of any of these documents by writing to Momenta Pharmaceuticals, Inc., 675 West Kendall Street, Cambridge, Massachusetts 02142, attention: Bruce A.

Corporate Governance Guidelines

        Our board of directors has adopted corporate governance guidelines to assist our board of directors in the exercise of its duties and responsibilities and to serve the best interests of Momenta and its stockholders. These guidelines, which provide a framework for the conduct of the board of directors' business, provide that:

Board Determination of Independence

        Under applicable NASDAQ rules, a director will only qualify as an "independent director" if, in the opinion of our board of directors, that person does not have a relationship which would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Our board of directors has determined that none of John K. Clarke, Bruce L. Downey, Marsha H. Fanucci, Peter Barton Hutt, Thomas Koestler, Bennett M. Shapiro, Elizabeth Stoner and James R. Sulat, from which group directors are currently selected to comprise our audit, compensation and nominating and corporate governance committees, has a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is "independent" as that term is defined under applicable NASDAQ rules.

        In determining the independence of the directors listed above, our board of directors considered the transaction discussed in "Certain Relationships and Related Transactions" below.

Board Leadership Structure

        Our board separated the positions of chairman of the board and chief executive officer in 2005. Separating these positions allows our chief executive officer to focus on our day-to-day business, while

11



allowing the chairman of the board to lead the board in its fundamental role of providing advice to and independent oversight of management. The board recognizes the time, effort, and energy that the chief executive officer is required to devote to his position, and further recognizes the commitment required to serve as chairman of the board, particularly as the board's oversight responsibilities continue to grow. While our bylaws and corporate governance guidelines do not require that our chairman and chief executive officer positions be separate, the board believes that our practice of having separate positions and having an independent outside director serve as chairman is the appropriate leadership structure for the company at this time. However, in the event that in the future the chairman of the board is not an independent director, our corporate governance guidelines provide that the nominating and corporate governance committee will nominate an independent director to serve as "Lead Director" who will be approved by a majority of the independent directors.

Board Meetings and Attendance

        Our board of directors met five times during the fiscal year ended December 31, 2010, either in person or by teleconference. During 2010, each director, with the exception of Dr. Ram Sasisekharan, who resigned from our board effective September 10, 2010, attended at least 75% of the aggregate of the total number of board meetings and the total number of committee meetings on which she or he then served. Quarterly board meetings are scheduled over a year in advance of the meeting, while special meetings of the board are scheduled for unanticipated matters close to the time of the meeting, usually at a time when not every director can be available.

Director Attendance at Annual Meetings of Stockholders

        Our corporate governance guidelines provide that directors are expected to attend the annual meeting of stockholders. All of our then-current directors, except Dr. Sasisekharan, attended the 2010 annual meeting of stockholders.

Board Committees

        Our board of directors has established four standing committees—audit, compensation, nominating and corporate governance and science—each of which operates under a charter that has been approved by our board of directors. Current copies of the audit, compensation, nominating and corporate governance and science committee charters are posted on the "Investors—Corporate Governance" section of our website located at www.momentapharma.com .

        Our board of directors has determined that all of the members of each of the audit, compensation and nominating and corporate governance committees are independent as defined under applicable NASDAQ rules, including, in the case of all members of the audit committee, the independence requirements contemplated by Rule 10A-3 under the Securities Exchange Act of 1934, as amended, or the Exchange Act.

        The audit committee currently consists of Marsha H. Fanucci, John K. Clarke, Bruce Downey and James Sulat. Ms. Fanucci chairs the audit committee. The audit committee held nine meetings in 2010. Our audit committee's responsibilities include:

12


        Our board of directors has determined that each of Marsha H. Fanucci, Bruce Downey, John K. Clarke and James Sulat is an "audit committee financial expert" as defined by applicable Securities and Exchange Commission rules.

        The compensation committee currently consists of John K. Clarke, Bruce Downey, Thomas Koestler and Bennett M. Shapiro. Mr. Clarke chairs the compensation committee. The compensation committee held eight meetings in 2010. Our compensation committee's responsibilities include:

        The processes and procedures followed by our compensation committee in considering and determining executive compensation are described below under the heading "Executive Compensation Processes."

        Our nominating and corporate governance committee currently consists of Peter Barton Hutt, Marsha Fanucci, Elizabeth Stoner and James Sulat. Mr. Hutt chairs the nominating and corporate

13


governance committee. The nominating and corporate governance committee held six meetings in 2010. Our nominating and corporate governance committee's responsibilities include:

        The processes and procedures followed by our nominating and corporate governance committee in identifying and evaluating director candidates are described below under the heading "Director Nomination Process."

        Our science committee currently consists of Thomas Koestler, Bennett M. Shapiro and Elizabeth Stoner. Dr. Shapiro chairs the science committee. The science committee held six meetings in 2010. Our science committee's responsibilities include:

The Board's Role in Risk Oversight

        Our board of directors administers its risk oversight function directly and through our board committees. The audit committee's role in the risk oversight process includes receiving regular reports from our compliance officer, who oversees our compliance program, members of senior management on our compliance committee who have functional compliance responsibility, and other members of senior management on areas of material risk to us, including operational, financial, legal, regulatory, strategic and reputational risks. The audit committee receives these reports from the appropriate "risk owner" within the company to enable the audit committee to understand our risk identification, risk management and risk mitigation strategies. The chairwoman of the audit committee reports on these discussions to the full board during each regularly-scheduled board meeting. The compensation committee assists the board in fulfilling its oversight responsibilities with respect to the management of risks arising from our compensation policies and programs. The nominating and governance committee assists the board in fulfilling its oversight responsibilities with respect to the management of risks associated with board organization, membership and structure, succession planning for our directors

14



and executive officers, and corporate governance, and by reviewing the code of business conduct and ethics which creates a foundation for our compliance program.

Executive Compensation Processes

        We have implemented an annual performance review program for our employees, including our executives, with annual corporate goals that are proposed by management, reviewed by the compensation committee and approved by the board of directors. These corporate goals target the achievement of specified operational and financial goals; specific research, clinical, regulatory, commercial and/or compliance milestones; and business development and financing initiatives. Individual performance is evaluated in part by reviewing the extent to which an employee's performance facilitates the achievement of our annual corporate and business goals. Annual salary changes, individual components of annual incentive cash bonus awards and equity awards for each of our Chief Executive Officer, Chief Financial Officer, and each of our three other most highly compensated executive officers are tied to a combination of achievement of corporate goals and individual performance.

        The compensation committee has the authority to retain compensation consultants and other outside advisors to assist in the evaluation of executive officer compensation. To assist the compensation committee in discharging its responsibilities, in June 2010 the compensation committee retained Radford Survey and Consulting, a business unit of AON, an independent compensation consultant that we refer to as Radford, to evaluate certain aspects of our compensation practices and assist the compensation committee with setting executive compensation.

        For further information about our executive compensation, please see the "Executive Compensation—Compensation Discussion and Analysis" section below.

Director Nomination Process

        The process followed by our nominating and corporate governance committee to identify and evaluate director candidates includes requests to board members for recommendations, meetings from time to time to evaluate biographical information and background material relating to potential candidates and interviews of selected candidates by members of the nominating and corporate governance committee and other members of the board of directors. In addition, during 2010, the nominating and corporate governance committee used the services of an executive search firm to help identify and evaluate potential director candidates.

        In considering whether to recommend any particular candidate for inclusion in the board's slate of director nominees, the nominating and corporate governance committee applies the criteria attached to its charter. These criteria include the candidate's integrity, business acumen, knowledge of our business and industry, experience, diligence, conflicts of interest and the ability to act in the interests of all stockholders. The criteria further specify that the value of diversity on the board should be considered by the nominating and corporate governance committee in the director identification and nomination process. While we do not have a formal policy on diversity, the nominating and corporate governance committee seeks nominees with a broad diversity of experience, professions, skills, gender, race, national origin and backgrounds and considers such factors in evaluating prospective nominees. The nominating and corporate governance committee does not assign specific weights to particular criteria and no particular trait is a prerequisite for each prospective nominee. We believe that the backgrounds and qualifications of our directors, considered as a group, should provide a composite mix of experience, knowledge and abilities that will allow the board of directors to fulfill its responsibilities. Nominees are not discriminated against on the basis of race, religion, national origin, gender, sexual orientation, disability or any other basis proscribed by law.

15


        Stockholders may recommend individuals to the nominating and corporate governance committee for consideration as potential director candidates by submitting their names, together with appropriate biographical information and background materials and a statement as to whether the stockholder or group of stockholders making the recommendation has beneficially owned more than 5% of our common stock for at least a year as of the date such recommendation is made, to the nominating and corporate governance committee, c/o Bruce A. Leicher, Secretary, Momenta Pharmaceuticals, Inc., 675 West Kendall Street, Cambridge, Massachusetts 02142. Assuming that appropriate biographical and background material has been provided on a timely basis, the nominating and corporate governance committee will evaluate stockholder-recommended candidates by following substantially the same process, and applying substantially the same criteria, as it follows for candidates submitted by others.

        Stockholders also have the right under our bylaws to directly nominate director candidates, without any action or recommendation on the part of the nominating and corporate governance committee or the board of directors, by following the procedures set forth in our amended and restated bylaws that are described below under the heading "Stockholder Proposals."

        In January 2011, Thomas Koestler was appointed by our board of directors as a new director. Dr. Koestler was originally proposed to the nominating and corporate governance committee by a search firm engaged to assist us in recruiting new members to the board of directors.

Communicating with the Independent Directors

        Our board of directors will give appropriate attention to written communications that are submitted by stockholders and will respond if and as appropriate. The chairman of the board of directors (if an independent director) or the lead director (if one is appointed), or otherwise the chairperson of the nominating and corporate governance committee, subject to advice and assistance from the general counsel and, if requested, outside legal counsel, is primarily responsible for monitoring communications from stockholders and for providing copies of summaries of such communications to the other directors as he or she considers appropriate.

        Under procedures approved by a majority of the independent directors, communications are forwarded to all directors if they relate to important substantive matters and include suggestions or comments that the chairman of the board considers to be important for the directors to know. In general, communications relating to corporate governance and corporate strategy are more likely to be forwarded than communications relating to ordinary business affairs, personal grievances and matters as to which we tend to receive repetitive or duplicative communications.

        Stockholders who wish to send communications on any topic to the board of directors should address such communications to board of directors c/o Bruce A. Leicher, Secretary, Momenta Pharmaceuticals, Inc., 675 West Kendall Street, Cambridge, Massachusetts 02142, facsimile (617) 621-0431.

Code of Business Conduct and Ethics

        We have adopted a written code of business conduct and ethics that applies to our directors, officers and employees, including our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions. We have posted a current copy of the code on our website, which is located at www.momentapharma.com under the Corporate Governance tab in the Investors section of our website. In addition, we intend to post on our website all disclosures that are required by law or NASDAQ Global Market listing standards concerning any amendments to, or waivers from, any provision of the code.

        Section 16(a) of the Exchange Act requires our directors, executive officers and the holders of more than 10% of our common stock to file with the Securities and Exchange Commission initial reports of ownership of our common stock and other equity securities on a Form 3 and reports of changes in such ownership on a Form 4 or Form 5. Officers, directors and 10% stockholders are required by Securities and Exchange Commission regulations to furnish us with copies of all Section 16(a) forms they file. Based solely on our review of copies of Section 16(a) reports furnished to us and representations made to us, we believe that, except as set forth below, during 2010 our officers, directors and holders of more than 10% of our common stock complied with all Section 16(a) filing requirements:

EXECUTIVE COMPENSATION

Compensation Discussion and Analysis

        The following discussion provides information regarding compensation earned by our Chief Executive Officer, our Chief Financial Officer, each of our three other most highly compensated executive officers and one additional individual who would have been one of the three most highly compensated executive officers but for the fact that he was not an executive officer at year end. We refer to these executive officers as our "Named Executives." When discussing compensation for the fiscal year ended December 31, 2011, the term "Named Executive" does not include Steven B. Brugger, who resigned as an executive of Momenta as of November 5, 2010.

Executive Summary

        The objective of our executive compensation program is to align the interests of management with the interests of stockholders through a system that correlates compensation to company-wide objectives and, to a lesser extent, individual performance. Our program is geared for short and long-term performance, with the goal of increasing stockholder value over the long term. We also emphasize employee retention in our program.

        Our "pay-for-performance" philosophy forms the foundation for the compensation committee's decisions regarding executive compensation. Like most companies, we use a combination of fixed and variable compensation programs to reward and incentivize strong performance, and to align the interests of our executives with our stockholders. This compensation philosophy, and the program structure approved by the compensation committee, is central to our ability to attract, retain and motivate individuals who can achieve the results that our stockholders expect.

        Our compensation committee has determined that our compensation program should be designed to:

    link pay to performance, measured on the corporate as well as individual level;

    reinforce business strategy and reflect and reinforce our values;

    reward teamwork and integrity;

    motivate our people to achieve meaningful results in support of our company goals;

    keep things simple to promote understanding and enable employees to make informed decisions; and

    retain our management team and our other employees.

        Our executive compensation philosophy is based on the following principles:

    Competitive and Fair Compensation.   We believe that the performance of our Chief Executive Officer, Chief Financial Officer, and each of our three other most highly compensated executive officers, or our Named Executives, should be viewed, and their overall compensation should be determined, in the context of our industry, the competitive landscape and our performance. While we do not have an exact formula for allocating between cash and non-cash compensation, we try to balance short-term cash compensation and long-term equity compensation by offering reasonable base salaries, market-competitive benefits and perquisites, annual incentive cash bonuses and opportunities for financial growth through our equity incentive programs. Cash and non-cash components are established separately and viewed distinctly by our compensation committee.

    Sustained Performance.   In determining total compensation, we stress a philosophy that is performance driven. Our Named Executives are primarily rewarded based upon an assessment of

19


      corporate performance and secondarily on individual performance. Corporate performance is evaluated by reviewing the extent to which established corporate goals are met. Individual performance is evaluated by reviewing how each Named Executive contributed in the context of overall corporate goals. Our compensation philosophy emphasizing performance permeates total compensation for both executives and non-executives. We believe that the design of our executive compensation program affects all of our employees and, because the performance of every employee is important to our success, we are cognizant of the effect that executive compensation may have on other employees.

        Compensation and benefits for employees at all levels, including for our Named Executives includes base salary, annual incentive cash bonuses, annual equity awards, and other benefits. Compensation for our Named Executives also includes severance and change-of-control payments. Other aspects of our compensation program are intended to further align the interest of our executives with our stockholders, including stock ownership guidelines that more closely align executives' interests with those of stockholders.

        The following pages of this Compensation Discussion and Analysis include the following:

    an overview of our program, including our policy on pay for performance;

    a description of the roles of those responsible for overseeing and implementing the compensation plan;

    a description of how we develop our competitive compensation structure, including how we use external data;

    a discussion of the impact of this analysis on the compensation of our Named Executives; and

    a summary of the other elements of executive officer compensation.

The compensation tables appear immediately following this Compensation Discussion and Analysis.

Background for 2010 Compensation

        In the fall of 2009, DolmatConnell & Partners, or DolmatConnell, an independent compensation consultant engaged by the compensation committee, provided the compensation committee analysis of and advice regarding our executive compensation program, including base salaries, short-term incentives and long-term incentives, as compared to our previously-determined peer group companies, which were:

ACADIA Pharmaceuticals, Inc.   Incyte Corporation
Adolor Corporation   Inspire Pharmaceuticals Inc.
Affymax Inc.   Maxygen Inc.
Alnylam Pharmaceuticals, Inc.   Progenics Pharmaceuticals Inc.
Array BioPharma Inc.   Rigel Pharmaceuticals Inc.
Dendreon Corporation   Seattle Genetics Inc.
Dyax Corp.   Synta Pharmaceuticals Corporation
Exelixis Inc.   Theravance Inc.
GTx Inc.   Xenoport Inc.
Idenix Pharmaceuticals, Inc.    

        In conducting its review, DolmatConnell considered the company's ability to continue to recruit, retain and motivate the executive team. DolmatConnell did not recommend any significant compensation adjustments for our executives in 2010.

        In addition, in order to determine the appropriate target level for company-wide salary increases for 2010, in September 2009 we obtained survey data from the following survey sources: The Survey

20



Group; WorldatWork; Hewitt Associates; Conference Board and Radford Survey and Consulting, or Radford. These surveys were utilized to assure that our proposed merit salary increases were competitive in the market. The projected merit salary increases for 2010 contained in the surveys were between 3.0% and 3.5% of current base salaries, with the Radford survey, the only industry-specific survey, projecting a 3.5% increase. Using this data, we set a target level of merit salary increase for 2010 at 3.5%.

Background for 2011 Compensation

        In September 2010, in light of the approval by the U.S. Food and Drug Administration of enoxaparin sodium injection, our first commercial product, we engaged Radford to examine our historical peer group companies and determine the appropriateness of retaining those companies as our peer group and/or identifying other suitable companies to be included in the peer group. Radford focused on creating a peer group that represented companies within our industry and captured companies at a similar stage of development with a similar financial profile as us.

        In reviewing and selecting potential peer group companies, Radford first identified all publicly traded, U.S.-headquartered companies in the biotechnology/pharmaceutical industry at or near the commercial stage. Radford next refined the pool to reflect companies with 50 to 600 employees, annual revenue between $30 million and $300 million and a market capitalization between $250 million to $2.5 billion. Radford next qualitatively evaluated and refined the pool to identify each company's business focus and corporate strategy, where publicly disclosed. Radford then selected companies that were similar to us, taking into consideration the financial profile and product stage of development for each company.

        In October 2010, the compensation committee reviewed and approved the peer group companies presented by Radford based on the above methodology and analysis, which are:

Acorda Therapeutics, Inc.   InterMune, Inc.
Alkermes, Inc.   Isis Pharmaceuticals, Inc.
Auxilium Pharmaceuticals, Inc.   Jazz Pharmaceuticals, Inc.
Dyax Corp.   Onyx Pharmaceuticals, Inc.
Enzon Pharmaceuticals, Inc.   Salix Pharmaceuticals, Inc.
Idenix Pharmaceuticals, Inc.   Seattle Genetics, Inc.
Impax Laboratories, Inc.   Spectrum Pharmaceuticals, Inc.
Incyte Corporation   Theravance, Inc.
Inspire Pharmaceuticals, Inc.   ViroPharma Incorporated

        In the fall of 2010, Radford provided analysis and advice of our executive compensation program, including base salaries, short-term incentives and long-term incentives, as compared to the new peer group companies. In conducting its review, Radford considered the company's ability to continue to recruit, retain and motivate the executive team.

        In addition, in order to determine the appropriate target level for company-wide salary increases for 2011, in the fall of 2010 we obtained survey data from the following survey sources: WorldatWork; Mercer; Hay Group; The Society for Human Resources Management; Conference Board and Radford. These surveys were utilized to assure that our proposed merit salary increases were competitive in the market. The projected merit salary increases for 2011 contained in the surveys were between 2.9% and 3.4% of current base salaries, with the Radford survey, an industry-specific survey, projecting a 3.4% increase. Using this data, we set a target level of merit salary increase for 2011 at 3.5%, with the goals of retaining a competitive compensation package and aligning internal compensation with external candidates coming into the company.

Stock Ownership Guidelines

        In September 2007, our board of directors, upon recommendation of the compensation committee, approved a stock ownership and retention program for our executive officers and directors. The purpose of the program is to ensure that each of our executive officers and directors has a long-term equity stake in Momenta, to more closely align the interests of the executive officers and directors with those of our stockholders and to further promote our commitment to sound corporate governance.

        Under the program's guidelines:

    our President and CEO is expected to hold shares of our common stock having an aggregate value equal to or greater than three times his or her annual base salary;

    other executive officers are expected to hold shares of our common stock having an aggregate value equal to or greater than one times their annual base salary; and

    non-employee directors are expected to hold shares of our common stock having an aggregate value equal to or greater than three times their then current annual base retainer for general board membership, excluding committee retainers, per-meeting or other similar fees.

        Our executive officers and directors are expected to comply with these guidelines by the later of March 31, 2013 and the fifth anniversary that each such person becomes subject to the guidelines. Until the applicable minimum share requirement is achieved, each executive officer and director is required to retain all shares of restricted stock upon the lapse of vesting restrictions, net of shares surrendered or sold to pay applicable withholding taxes. Once an executive officer or director has met these guidelines, he or she must continue to satisfy the guidelines so long as he or she remains subject to the guidelines. Each executive officer and director's satisfaction of the minimum share requirement will be measured on an annual basis. Shares that count toward satisfaction of the guidelines include:

    shares of common stock owned outright by the executive officer or director or his or her spouse or minor children;

    shares of common stock held in trust for the benefit of the executive officer or director or his or her spouse or minor children; and

    restricted stock or restricted stock units for which applicable restrictions have lapsed.

        The minimum share requirement may be waived, at the discretion of the compensation committee, if compliance would create severe hardship, would prevent an executive officer or director from complying with a court order, as in the case of a divorce settlement, or when he or she attains the age of 62.

Determining Executive Compensation—Roles and Process

        Utilizing the philosophy and background outlined above, our compensation committee determines the parameters of the executive compensation program, including appropriate target levels and performance measures, and administers our executive compensation program. This section discusses in greater detail the roles and process underlying the application of our executive compensation philosophy.

    Role of CEO in Compensation Decisions

        The CEO's role in the compensation process begins with the establishment of our corporate and business performance objectives against which the payment of annual incentive bonus awards will be measured. Our CEO, together with our executive team, discusses and formulates annual corporate and business goals. These goals are presented to our compensation committee, which reviews and finalizes the goals and recommends them for approval by our board of directors. The CEO's role in the

22


compensation process continues with his review of our Named Executives. Our CEO elicits 360-performance reviews with respect to each of our Named Executives. These 360-performance reviews are evaluations of each Named Executive that are submitted to our CEO by our employees who interact with these Named Executives. Each executive also completes a written self-assessment which is submitted to the CEO. The CEO then assimilates the feedback from the 360-performance reviews and the self-assessment into formal written evaluations of each Named Executive, including the CEO's own evaluation of the Named Executive. The CEO's evaluation also includes documenting each Named Executive's performance during the year, detailing accomplishments, areas of strength and areas for development. The CEO bases this evaluation on his knowledge of each Named Executive's performance and feedback provided by the 360-performance reviews. Each Named Executive is then rated based on his or her performance during the year. The CEO then works directly with our Senior Vice President, Human Resources to provide comprehensive recommendations for salary changes, individual components of annual incentive cash bonus awards and equity awards for each of our Named Executives. These recommendations are presented to, reviewed by, modified or accepted, and approved by our compensation committee. The CEO then meets with each Named Executive and reviews his or her respective performance evaluation and compensation changes, if any.

        At the request of the compensation committee, our CEO attends all or portions of periodic meetings of the compensation committee, but does not attend portions of any meeting in which the compensation committee discusses his compensation or performance. In addition, our compensation committee reviews the information with respect to executive compensation trends among our peer-group companies, including the overall blend of salary, bonus and equity compensation within such group, presented by our Senior Vice President, Human Resources and her recommendations pertaining to our executive compensation program. As discussed below, the compensation committee also reviews data and recommendations from compensation consultants.

        The compensation committee has delegated to our CEO the authority to make stock option grants under our 2004 Stock Incentive Plan, as amended, to newly-hired employees below the senior director level based on a number of options within a range as set forth in a matrix previously approved by the board of directors.

    Role of the Compensation Committee

        Our compensation committee recognizes the importance of maintaining sound principles for the development and administration of our compensation program, which is intended to strengthen the link between executive pay and performance. The compensation committee, in accordance with its written charter, oversees all aspects of our director, officer and other executive compensation policies. Based on the process described under the caption " Role of CEO in Compensation Decision," above, the CEO, together with our Senior Vice President, Human Resources, makes a recommendation to the compensation committee on each Named Executive's compensation, except his own. Named Executives do not propose or seek approval for their own compensation. The compensation committee then determines the compensation of each of these Named Executives. The chairman of the board and the chairman of the compensation committee evaluate the CEO's performance, utilizing input from the board of directors and from selected executive officers in connection with an annual 360-performance review, and make recommendations to the compensation committee, which then determines the CEO's compensation.

    Role of External Advisors

        To assist it in discharging its responsibilities, our compensation committee utilized one independent compensation consultant, Radford, to evaluate certain aspects of our compensation practices and to assist in making recommendations for our board of directors and executive compensation programs. As part of this process, members of the compensation committee reviewed materials provided by our

23


compensation consultants, and had the opportunity to meet independently with Radford periodically throughout the year to discuss our executive and director compensation and to receive input and advice. Any written reports and studies provided by Radford to management are provided to the compensation committee. Radford did not provide any other services to us other than those described in this Executive Compensation section.

        We do not use "internal pay equity" as a constraint on compensation paid to our CEO or other Named Executives. Such systems typically put a ceiling on part or all of an executive's compensation based on a specified multiple of compensation awarded to another executive or a class of employees of the company. Our management and our compensation committee do not believe that such arbitrary limitations are an appropriate way to make compensation decisions for our executives. Instead, we rely on the judgment of the compensation committee, after considering recommendations from management and external advisors, available market data and evaluations of executive performance, in the context of a program that is weighted heavily in favor of performance-based compensation for our Named Executives.

Elements of Compensation

        Our compensation program is designed to reward each Named Executive based upon a combination of corporate and individual performance. Corporate performance is evaluated by reviewing the extent to which pre-set goals are met, which generally include the achievement of specified operational and financial goals; specific research, clinical, regulatory, commercial or compliance milestones; and business development and financing initiatives. We evaluate individual performance in part by reviewing the extent to which individual performance facilitated the achievement of the corporate and business goals discussed above.

        The compensation package offered to each Named Executive is comprised of a combination of:

    base salary;

    annual incentive cash bonus awards;

    annual equity awards;

    other benefits, such as health, dental, disability and life insurance; and

    severance and change-of-control payments.

        We maintain broad-based benefits that are provided to eligible employees, including health, dental, life and disability insurance and a 401(k) plan. Our Named Executives are eligible to participate in all of our employee benefit plans, in each case on the same basis as other employees.

        Base Salary.     Base salaries are established for our Named Executives at levels that are intended to reflect the scope of each Named Executive's industry experience, knowledge and qualifications, salary levels in effect for comparable positions within our peer group companies and internal comparability considerations. We believe that base salaries are a fundamental element of our executive compensation program. Base salaries are reviewed at least annually by our compensation committee and are adjusted from time to time to ensure that our executive compensation structure remains aligned with our compensation objectives and are based upon various subjective criteria and the compensation paid by peer group companies. Subjective performance criteria include an executive's ability to lead through motivating and inspiring others, demonstrate the skills necessary to perform effectively in his or her area of responsibility, recognize and pursue new business opportunities and initiate programs that enhance our growth and success.

    2010 Base Salary

        The compensation committee reviewed the salaries of the Named Executives at its February 2010 meeting. The compensation committee had previously approved a 3.5% merit increase for all employees in connection with its review of survey data of industry trends. The compensation committee used that target as well as performance review input for each of the Named Executives to approve salary increases to be effective as of January 1, 2010. The peer group data indicated that Dr. Venkataraman's salary was at the 25 th  percentile of for others in his role within the peer group and the compensation committee determined that Dr. Venkataraman should be at the 50 th  percentile. Based on the foregoing information, the compensation committee approved salary increases for the Named Executives to be effective as of January 1, 2010 as set forth below:

    2011 Base Salary

        The compensation committee reviewed the salaries of the Named Executives at its January 2011 meeting. The compensation committee had previously approved a 3.5% merit increase for all employees in connection with its review of survey data of industry trends. The compensation committee used that target as well as performance review input for each of the Named Executives to approve salary increases to be effective as of January 1, 2011. In addition, the compensation committee noted that peer group data showed that the salary for Mr. Shea was below the 25 th  percentile of others in his role within our peer group and that Mr. Wheeler's cash compensation was below the 50 th  percentile of others in his role within our peer group. The Committee agreed to move both executives' salary closer to the 50 th  percentile of our peer group. Based on the foregoing information, the compensation committee approved a salary increase for the Named Executives to be effective as of January 1, 2011 as set forth below:

        Annual Incentive Cash Bonus.     We use annual incentive cash bonuses to motivate our Named Executives to achieve and exceed specified goals in a time frame that is one year in duration. Annual incentive cash bonuses are determined on the basis of our achievement of corporate performance targets and individual contribution toward those corporate goals. Our corporate goals are typically focused upon the achievement of specific research, clinical, regulatory, commercial, financial, compliance or operational milestones. These goals are also considered to be conducive to the creation of stockholder value and designed to contribute to our current and future financial success.

        Under our annual incentive cash bonus program, corporate goals are proposed by management and approved by the compensation committee and the board of directors. Each corporate goal is assigned a percentage value (e.g., 10%, 15%, 20%, etc.) and within each corporate goal there are achievement milestones that are expressed in the following target percentages: 70%, 100% and 130%. If a corporate goal does not meet at least the 70% target percentage, no achievement percentage is assigned. If, for example, we were to achieve 100% of our corporate goals, but only to the extent of the 70% target percentage within each goal, the annual bonus pool for that year would be 70% of the aggregate bonus potential for all participants. In addition, our compensation committee has the discretion to take into consideration mitigating and/or extraordinary circumstances when determining the level of achievement of goals and related milestones. The CEO's annual incentive bonus award is completely dependent upon the achievement of corporate goals, and senior vice presidents' and vice presidents' target bonuses are 75% dependent upon the achievement of corporate goals and 25% dependent upon the subjective analysis of their individual performance in relation to the corporate goals.

        The target bonus potential for the CEO is 60% of base salary, with a maximum bonus opportunity equal to 150% of his base salary. The target bonus potential for the other Named Executives is 35% of base salary for senior vice presidents. Bonuses, if any, are determined and paid on an annual basis after completion of the fiscal year in which bonuses are earned.

        The corporate goals for 2010 were:

    enabling manufacturing of enoxaparin sodium injection (10%);

    advancing our M356, biologics and M402 programs (25%, 15% and 10% respectively);

    achievement of business development goals (15%);

    advancement of our corporate strategic plan (15%); and

    achievement of financial discipline goals (10%).

        In assessing the achievement of these goals, the compensation committee considered the recommendations of our CEO, who, with input from the other executive officers, assessed our performance against corporate goals for 2010 and made recommendations to the board of directors and the compensation committee. The compensation committee then reviewed and discussed these recommendations, taking into account mitigating and/or extraordinary circumstances. In January 2011, the compensation committee made a determination of the achievement of the corporate goals at 85% and, in its discretion, awarded an additional 25% to the achievement level of corporate goals related to significant achievements during the year, including successfully managing U.S. Food and Drug inspections of Chinese heparin suppliers; maintaining sole approval of enoxaparin sodium injection through the end of 2010; manufacturing for the enoxaparin sodium injection program exceeding the 130% goal; successful management of enoxaparin-related litigation; and achievements in the M356 and glycoprotein development programs. As a result, the compensation committee concluded that, including

26


the additional achievements, our total achievement level of the 2010 corporate goals was 110%, as follows:

        In January 2011, the compensation committee reviewed each Named Executive's performance recommendation as submitted by the CEO and our Senior Vice President, Human Resources. The individual objectives for our Named Executives included meeting specified targets in the following areas: successfully managing the business to the budget; business development achievements; pipeline development; and strategic planning. Based on the 110% corporate goal achievements (weighted 100% for Mr. Wheeler and 75% for all other Named Executives), and subjective analysis of their individual performance in relation to the corporate goals (weighted 25% for all Named Executives except Mr. Wheeler), in February 2011, we paid bonuses to our Named Executives for their performance in 2010 representing the following percentages of base salary as of December 31, 2010:

Bruce A. Leicher

    35 % $ 129,743     38.5 %   110.0 %

        In January 2011, our compensation committee met to establish corporate goals for 2011, which are enabling manufacture of enoxaparin sodium injection (15%); advancing our M356, M402, research and follow-on biologics programs (25%, 10%, 10% and 5%, respectively); achievement of business development goals (15%); advancement of our corporate strategic plan (10%); and achievement of financial discipline goals (10%).

        Special Cash Bonus 2010.     In August 2010, our compensation committee approved a special bonus to all employees related to our approval and successful launch of enoxaparin sodium injection as the first generic to Lovenox®. The approval was a major milestone for us and the compensation committee wanted to reward the hard work and effort of our employees over a number of years that had gone into achieving the milestone.

        In 2009, the company had a corporate goal for enoxaparin sodium injection approval and product launch that was equal to 30% of the corporate goals if multiple generic products were approved and 39% of the total corporate goals in the event that the approval was also the first generic in the marketplace. With this background, the special bonus payment was targeted to equal 40% of an

27



individual's annual target bonus. As a result, in August 2010, we paid special bonuses to our Named Executives as follows:

        Equity Awards.     Compensation for employees, including executive officers, also includes equity awards designed to align the long-term interests of our employees and our stockholders and to assist in the retention of executives. We believe that equity compensation is a critical component of competitive compensation in the industry in which we operate.

        We award initial stock option grants to executives when they join Momenta or are promoted to executive officer. The size of an initial stock option grant is generally targeted to be within a pre-set range and is approved by the compensation committee. Initial stock option grants typically vest as to 25% of the shares subject to such option one year from the date of grant and 6.25% of the shares subject to such option vest on a quarterly basis thereafter. Annual performance grants are also made pursuant to a pre-set range approved by the board of directors and set forth on a matrix that is generally intended to reflect the level of the employee's position with us as well as an individual's performance relative to his or her goals and other employees at the same performance and position level. These stock option grants are typically made annually in conjunction with the review of individual performance. This review takes place at the beginning of each fiscal year for performance in the previous year, and is reviewed and awarded annually, typically at the regularly scheduled meeting of the compensation committee following completion of company-wide performance reviews. Performance options generally vest quarterly over a four-year period commencing three months from the date of grant. Stock option grants, whether made either by the CEO or by the compensation committee, are made on regularly-scheduled monthly dates that occur outside of regularly scheduled quarterly financial blackout periods.

        We have also made restricted stock awards to our CEO and executives as a complement to granting stock options in order to balance the volatility of the price of stock options and to assist with compliance with our stock ownership guidelines. In addition, we have made special restricted stock awards from time to time. When such restricted stock has been awarded, the circumstances were carefully evaluated and we focused on factors such as the individual's contribution to Momenta, his or her importance to Momenta and, in some cases, the achievement of key milestones.

        For 2010 performance, our compensation committee approved annual stock option grants to all of our employees, including the Named Executives, and also approved the award of restricted stock to executives, including the Named Executives. The compensation committee does not use a quantitative formula to relate option grants or restricted stock awards to the degree to which an individual achieved his or her goals for a particular year. Goal achievement and non-goal specific activities are considered when making the assessment of an executive's overall contribution. The compensation committee intends that the annual aggregate value of awards (using the Black Scholes or equivalent valuation methodology) to executives will be set near competitive levels for companies represented in the compensation data it reviews from its compensation consultants.

28


        The compensation committee reviewed equity awards for 2010 performance of the Named Executives in February 2011. At that meeting, the compensation committee approved the following equity awards our Named Executives as follows:

Name
  Number of Shares of
Common Stock Underlying
Stock Options(1)
  Shares of Restricted
Common Stock(2)
 

Craig A. Wheeler

    100,000     75,000  

Richard P. Shea

    23,178     9,271  

James M. Roach

    23,178     9,271  

Ganesh Venkataraman

    25,495     10,198  

Bruce A. Leicher

    23,178     9,271  

(1)
The shares of common stock underlying these options vest as to 6.25% of the shares at the end of each three-month period after the date of grant.

(2)
These shares of common stock are subject to a restricted stock agreement, pursuant to which 25% of such shares vest and become free from forfeiture on the first anniversary of the date of grant and an additional 6.25% of the shares vest and become free from forfeiture at the end of each successive three-month period thereafter.

        Special Equity Award 2011.     In March 2011, our compensation committee approved awards of restricted stock to all employees with vesting tied to approval by the U.S. Food and Drug Administration of the abbreviated new drug application for M356, our generic version of Copaxone®, currently under review. If approved, this will be a major milestone for us and the compensation committee wanted to provide incentive and reward to employees in the event of approval. As a result, awards of restricted stock were made to our Named Executives as follows:

Name
  Shares of Restricted
Common Stock(1)
 

Craig A. Wheeler

    147,500  

Richard P. Shea

    45,000  

James M. Roach

    45,000  

Ganesh Venkataraman

    45,000  

Bruce A. Leicher

    45,000  

(1)
Fifty percent of the shares vest on the date that we (or any of our partners or collaborators) receive marketing approval from the U.S. Food and Drug Administration for M356 in the United States provided that approval occurs on or before March 28, 2015, and the remaining fifty percent of the shares vest on the first anniversary of such initial vest date; provided, however that all of the shares shall vest if we consummate a transaction whereby our tangible or intangible assets in or related to M356 are transferred to a third party.

        Timing and Pricing of Option Grants.     The compensation committee's procedure for timing of equity grants is intended to ensure that grant timing is not manipulated to result in a price that is favorable to employees. Commencing in 2007, the annual equity grant date for all eligible employees, including the Named Executives, is the date of the regularly scheduled meeting of the compensation committee following completion of company-wide performance reviews. The grant date timing is driven by the fact that it coincides with our calendar-year-based performance management cycle, allowing us to deliver the equity awards close in time to performance appraisals, which increases the impact of the awards by strengthening the link between pay and performance.

29


        Aside from the annual equity grant, it is our policy that options will normally be granted:

    to non-employee members of the board of directors, on the date of our annual general meeting each calendar year; and

    to newly-hired employees on regularly scheduled monthly dates after their date of hire, which monthly dates are scheduled outside of quarterly earnings blackout periods.

        The compensation committee sets the exercise price of all stock options to equal the closing price of our common stock on NASDAQ Global Market on the day before the date of grant in the case of annual non-employee director grants, and the date of grant for all other grants.

        Other Elements of Compensation and Perquisites.     In order to attract, retain and pay market levels of compensation, we provide our executive officers and other employees the following benefits and perquisites:

        Medical Insurance.     We provide to our Named Executives, their spouses, domestic partners and children, health, dental and vision insurance coverage that we generally make available to other employees. We pay a portion of the premiums for this insurance for all employees.

        Life and Disability Insurance.     We provide each Named Executive disability and/or life insurance that we may from time to time make available to other executive employees of the same level of employment. Our CEO also receives reimbursement for an additional $3.0 million dollar life and disability policy, capped at a maximum of $5,000 of reimbursement premium per year.

        Defined Contribution Plan.     We offer a Section 401(k) Savings/Retirement Plan, or the 401(k) Plan, a tax-qualified retirement plan, to eligible employees. The 401(k) Plan permits eligible employees to defer up to 60% of their annual eligible compensation, subject to certain limitations imposed by the Internal Revenue Code, which we refer to as the Code. The employees' elective deferrals are immediately vested and non-forfeitable in the 401(k) Plan. In any plan year, we will contribute to each participant a matching contribution equal to 50% of the first 6% of the participant's compensation that he or she has contributed to the plan. Our contribution is subject to vesting at the rate of 25% at the end of each year over the first four years of employment. All of our Named Executives participated in the 401(k) Plan during 2010 and received matching contributions.

        Employee Stock Purchase Plan.     We also offer an Employee Stock Purchase Plan, or the ESPP. The ESPP is available to all of our employees, including the Named Executives, who work more than 20 hours in a week and five months during the course of a year. Under the ESPP, eligible participants purchase shares of our common stock at a discount of 15% from the fair market value of the lower of the beginning date or end date of the applicable purchase period. The purchase dates occur on the last business day of January and July of each year. To pay for the shares, each participant may authorize periodic payroll deductions ranging from 1% to 15% of his or her cash compensation, subject to certain limitations imposed by applicable law. All payroll deductions collected from the participant during a plan period are automatically applied to the purchase of common stock on that period's purchase date provided the participant remains an eligible employee and has not withdrawn from the ESPP prior to that date.

        Other.     We make available certain other perquisites or fringe benefits to all eligible employees, including the Named Executives, such as tuition reimbursement, parking fees, mass transit commuting passes, professional society dues, gym subsidies, cell phones and food and recreational fees incidental to official company functions, including board meetings. The CEO is also entitled to financial and tax advice and reimbursement of expenses in connection with using his personal airplane for business purposes (up to the equivalent amount of a first class commercial fare per usage).

30


        Severance and Change-of-Control Benefits.     Pursuant to employment agreements we entered into with Messrs. Wheeler, Shea, Roach, Venkataraman and Leicher, these Named Executives are entitled to specified benefits in the event of the termination of their employment under specified circumstances, including termination without cause and for good reason following a change of control of Momenta.

        We believe that severance protections, particularly in the context of a change-of-control transaction, can play a valuable role in attracting and retaining executive officers, are an important part of an executive's compensation and are consistent with competitive practices. Accordingly, we provide such protections for our Named Executives and certain other executive officers. We believe that the occurrence, or potential occurrence, of a change-of-control will create uncertainty regarding the continued employment of our Named Executives. This uncertainty results from the fact that many change-of-control transactions result in significant organizational changes, particularly at the senior executive level. Our practice, in the case of our employment agreements, has been to structure these change-of-control benefits as "double trigger" benefits. In other words, the change of control does not itself trigger benefits; rather, benefits are paid only if the employment of the Named Executive is terminated during the twelve-month (or 24-month in the case of the CEO) period after the change of control. We believe a "double trigger" benefit maximizes stockholder value because it prevents an unintended windfall to executives in the event of a friendly change of control, while still providing them appropriate incentives to cooperate in negotiating any change of control in which they believe they may lose their jobs. Because we believe that a termination by the executive for good reason is conceptually the same as a termination by us without cause, and that in the context of a change-of-control potential acquirers would otherwise have an incentive to constructively terminate the executive's employment to avoid paying severance, we provide severance benefits in these circumstances. We have provided more detailed information about these benefits, along with estimates of their value under various circumstances, under the captions "—Employment, Severance and Change of Control Arrangements" and "—Potential Termination and Change of Control Payments" below.

Tax Considerations

        It is generally our policy to qualify compensation paid to executive officers for deductibility under section 162(m) of the Code. Section 162(m) generally prohibits us from deducting the compensation of certain executive officers that exceeds $1,000,000 per person unless that compensation is based on the satisfaction of objective performance goals. However, we reserve the discretion to pay compensation to our executive officers that may not be deductible.

Employment, Severance and Change of Control Arrangements

Craig A. Wheeler Employment Agreement

        On August 22, 2006, we entered into an employment agreement with Craig A. Wheeler, pursuant to which Mr. Wheeler serves as our President and CEO and as a member of the board of directors. In December 2010, Mr. Wheeler's employment agreement was amended to ensure compliance with Section 409A of the Internal Revenue Code of 1986, as amended. Pursuant to his employment agreement, Mr. Wheeler receives an annual base salary determined by the compensation committee, which is $576,467 for 2011. Mr. Wheeler is also eligible to receive bonuses of up to 150% of his base salary for the applicable fiscal year, with an annual bonus target of 60% of the then-applicable base salary. The compensation committee approved a $362,351 bonus paid to Mr. Wheeler in 2011 based on our achievement of corporate goals in 2010. Mr. Wheeler is also entitled to specified benefits, including: participation in our sponsored benefit programs; reimbursement for life insurance premium expenses and related tax gross-up payments; and reimbursement of tax and financial advisor fees incurred by Mr. Wheeler during the period of his employment.

    Equity Awards

        Mr. Wheeler's employment agreement provides for the grant or issuance, as applicable, of the following stock-based awards:

        1.     On August 22, 2006, we granted Mr. Wheeler options to purchase an aggregate of 375,000 shares of common stock at an exercise price of $16.18 per share, which is referred to as the Initial Option Grant. The Initial Option Grant vested as to 25% of the shares subject to such option on August 22, 2007 and as to 6.25% of the shares subject to such option at the end of each three-month period thereafter.

        2.     On August 22, 2006, we issued 100,000 shares of restricted common stock to Mr. Wheeler, which is referred to as the Time-Based Grant. The shares of common stock subject to the Time-Based Grant vested and became free from forfeiture on the fourth anniversary of the date of issuance.

36


        3.     On January 17, 2007, we issued to Mr. Wheeler 175,000 shares of restricted common stock, which is referred to as the Performance Grant. The shares of common stock subject to the Performance Grant vested and became free from forfeiture on August 2, 2010, the date that Sandoz, Inc. commercially launched enoxaparin sodium injection in the United States.

        4.     In addition to the Initial Option Grant, the Time-Based Grant and the Performance Grant, on February 22, 2008, we granted Mr. Wheeler (i) 75,000 shares of restricted common stock subject to vesting over four years, which is referred to as the First Target Grant and (ii) an option to purchase 100,000 shares of common stock subject to vesting over four years, with an exercise price of $7.41 per share, which is referred to as the Second Target Grant.

        Beginning in 2009, the grant of stock-based awards to Mr. Wheeler is at the discretion of the board of directors in accordance with the overall equity practices of the company.

    Termination of Employment

        In the event that Mr. Wheeler's employment is terminated by us without cause, by reason of his death or disability or by him for good reason, other than in connection with a change in control (as those terms are defined in his employment agreement):

    the vesting schedules applicable to the Initial Option Grant and the Time-Based Grant will be fully accelerated and the shares thereunder fully vested,

    the vesting schedules applicable to the First Target Grant and Second Target Grant will accelerate by an additional 12 months and

    the vesting schedule applicable to all other stock-based awards held by Mr. Wheeler at the time of such termination will accelerate by 25%.

        In the event Mr. Wheeler's employment is terminated by us without cause within 24 months following a change of control (as such term is defined in the employment agreement) or is terminated by Mr. Wheeler for good reason within 24 months following a change of control, the unvested portions of the First Target Grant, the Second Target Grant and all future stock-based awards shall fully and immediately vest.

        Under his employment agreement, Mr. Wheeler or Momenta may terminate his employment at any time. In the event Mr. Wheeler's employment is terminated without cause by us, as the result of death or disability or Mr. Wheeler terminates his employment for good reason, other than in connection with a change in control, we have agreed to pay Mr. Wheeler a lump sum equal to:

    12 months of the highest base salary in effect during the 12 months prior to the date of termination and

    the greater of 60% of Mr. Wheeler's base salary or his last paid bonus.

Additionally, Mr. Wheeler and his dependents will receive comparable benefits for a maximum of 12 months following such termination subject to his re-employment with comparable benefits.

        If Mr. Wheeler terminates his employment for good reason within 24 months following a change of control of Momenta, or if we terminate Mr. Wheeler's employment without cause within 24 months following a change of control, we have agreed to pay Mr. Wheeler a lump-sum cash payment equal to:

    24 months of Mr. Wheeler's highest base-salary in effect during the 12 months prior to termination of his employment,

    an amount equal to the greater of 60% of Mr. Wheeler's last two years of base salary or two times the last bonus paid to Mr. Wheeler, and

37


    if the aggregate purchase price paid in a change of control transaction equals or exceeds $1.1 billion, an additional amount equal to 12 months of base salary in effect at the time of Mr. Wheeler's termination and the greater of 60% of one year of base salary or the last bonus paid to Mr. Wheeler.

Additionally, Mr. Wheeler is entitled to a tax gross-up payment following such termination and Mr. Wheeler and his dependents will receive comparable benefits for a maximum of 36 months following such termination subject to his re-employment with comparable benefits.

    Other Provisions

        Our employment agreement with Mr. Wheeler also contains non-disclosure, non-competition and assignment of intellectual property terms. These terms provide for the protection of our confidential information, the transfer of ownership rights to intellectual property developed by Mr. Wheeler to us and a 12-month non-compete provision.

Executive Employment Agreements with Richard P. Shea, James Roach, Ganesh Venkataraman and Bruce A. Leicher

        We have also entered into executive employment agreements, or the Executive Employment Agreements, with Richard P. Shea, James Roach, Ganesh Venkataraman and Bruce A. Leicher. In December 2010, each of the Executive Employment Agreements was amended to ensure compliance with Section 409A of the Internal Revenue Code of 1986, as amended.

    Salary, Bonus and Benefits

        Pursuant to the Executive Employment Agreements, we have agreed to pay Messrs. Shea, Roach, Venkataraman and Leicher annual base salaries as determined by the compensation committee. If our board of directors approves an annual bonus, Messrs. Shea, Roach, Venkataraman and Leicher will be eligible for a discretionary bonus award. The annual target for each executive's bonus will be 35% of the executive's annualized base salary. The compensation committee will determine, in its sole discretion, whether (and in what amount) a bonus award is payable to each executive. In order to be eligible for any bonus hereunder, the executive must be an active employee of Momenta on the date such bonus is paid.

        Each executive shall be entitled to participate in all benefit plans and programs that we establish and make available to our employees to the extent that the executive is eligible under (and subject to the provisions of) the plan documents governing those programs.

    Payments Upon Resignation by the Executive Without Good Reason or Termination by Us for Cause

        If the executive voluntarily resigns his employment other than for good reason (as defined in each Executive Employment Agreement), or if we terminate the executive for cause (as defined in each Executive Employment Agreement), we shall pay the executive all accrued and unpaid base salary through the executive's date of termination and any vacation that is accrued but unused as of such date. The executive shall not be eligible for any severance or separation payments or any continuation of benefits (other than those provided for COBRA), or any other compensation pursuant to the Executive Employment Agreement or otherwise. The executive also shall have such rights, if any, with respect to outstanding stock options and restricted stock grants as may be provided under each applicable agreement.

38


    Payments Upon Termination by Reason of Death or Disability, Termination Without Cause or Resignation for Good Reason

        If the executive's employment with us is terminated by reason of the executive's death or disability (as defined in each Executive Employment Agreement), by us without cause, or by the executive's voluntary resignation for good reason, other than in connection with a change in control (as defined in each Executive Employment Agreement), then the executive shall be paid all accrued and unpaid base salary and any accrued but unused vacation through the date of termination. In addition, the executive shall be eligible to receive the following separation benefits:

    an amount equal to the sum of 12 months of the executive's base salary as of the date of termination and the greater of (i) the annual discretionary target bonus established by our board of directors (or any other person or persons having authority with respect thereto) for the executive for the fiscal year in which the date of termination occurs or (ii) the annual bonus paid to the executive for the most recently completed fiscal year;

    insurance, medical, dental, health and accident and disability benefits as in effect immediately prior to the termination date for a period of 12 months; and

    continued vesting of any unvested stock options and any future stock option grants awarded to the executive after the date of the Executive Employment Agreement for a period of 12 months from the date of termination and an extension of the right to exercise any outstanding stock options on the earlier of three months after such 12-month period or the original expiration date of the applicable outstanding stock option. The executive shall also be entitled to immediate vesting, on the date of termination, of any restricted stock awards with underlying shares that vest solely through the passage of time (i.e., service-based vesting) and not upon the achievement of specified conditions or milestones (i.e., performance-based vesting), including any future restricted stock awards granted to the executive after the date of the Executive Employment Agreement that contain service-based vesting provisions, in each case that would have vested during the period of 12 months from the date of termination.

    Payments Upon Termination in Connection with a Change of Control

        If the executive's employment with the Company is terminated without cause or if the executive terminates his employment with good reason within one year following a change in control (as defined in each Executive Employment Agreement), the executive shall be entitled to all accrued and unpaid base salary and any accrued but unused vacation through the date of termination. In addition, the executive shall be eligible to receive the following separation benefits:

    an amount equal to the sum of 12 months of the executive's base salary as of the date of termination and the greater of (i) the annual discretionary target bonus established by our board of directors (or any other person or persons having authority with respect thereto) for the executive for the fiscal year in which the date of termination occurs or (ii) the annual bonus paid to the executive for the most recently completed fiscal year;

    insurance, medical, dental, health and accident and disability benefits as in effect immediately prior to the termination date for a period of 12 months; and

    immediate vesting of any unvested stock options, restricted stock awards and any future grants awarded to the executive. All such equity awards (whether stock options or restricted stock grants) will remain exercisable in accordance with the applicable stock option plan or grant agreement.

    Non-Competition, Non-Solicitation, Confidential Information and Developments

        Each of Messrs. Shea, Roach, Venkataraman and Leicher have entered into agreements providing for the protection of our confidential information, the transfer of ownership rights to intellectual property developed by each such executive to us and a 12-month non-compete provision.

Consulting Agreement with Mr. Brugger

Brugger on substantially the terms described above in "—Employment, Severance and Change of Control Agreements—Executive Employments Agreements with Richard P. Shea, James M. Roach, Ganesh Venkataraman and Bruce A. Leicher." In conjunction with his resignation as our chief operating officer, effective as of November 5, 2010, we entered into a letter agreement with Mr. Brugger regarding his termination of employment and entry into a consulting agreement, which letter agreement terminated the executive employment agreement and reaffirmed Mr. Brugger's obligations under the employee nondisclosure, noncompetition and assignment of inventions agreement Mr. Brugger is party to with us. Pursuant to the terms of the consulting agreement, we will pay Mr. Brugger $270 per hour for consulting services actually rendered during the consulting term which began November 6, 2010 and continues through June 30, 2011 (or such earlier date as may be determined by the parties). Pursuant to the terms of the option grants made to Mr. Brugger by us, his stock options will continue to vest and remain exercisable during the term of his consulting agreement with us.

In such event, Mr. Wheeler is entitled to an additional lump sum payment equal to 12 months of the highest base salary in effect for Mr. Wheeler during the 12 months prior to his termination, or $549,016, plus an amount equal to 60% of such base salary, or $329,410.

(5)
Represents benefits payable over 12 months for continuation of coverage under medical and dental plans for Mr. Wheeler and his dependents subject to Mr. Wheeler's re-employment with comparable healthcare benefits. The value is based upon the type of insurance coverage we carried for Mr. Wheeler as of December 31, 2010 and is valued at the premiums in effect on December 31, 2010.

(6)

In the event the aggregate purchase price is less than $1.1 billion, Mr. Wheeler would be entitled to 24 months continuation of coverage under medical and dental plans for Mr. Wheeler and his dependents subject to Mr. Wheeler's re-employment with comparable healthcare benefits, with a value equal to $43,922. This value is based upon the type of insurance coverage we carried for Mr. Wheeler as of December 31, 2010 and is valued at the premiums in effect on December 31, 2010.

However, the exercise price of $15.37 per share for the 100,000 shares of common stock subject to stock options granted to Mr. Wheeler on February 18, 2010 is above the last sale price on December 31, 2010, and therefore has no market value at that date. If Mr. Wheeler's employment with us is terminated without cause in periods after December 31, 2010, acceleration of vesting to additional equity awards will apply.

Compensation of Directors

        Non-employee director compensation is set by our board of directors at the recommendation of the compensation committee. In March 2011, we retained Radford to assess our non-employee director compensation practices and provide recommendations for changes to the program, if any. The updated peer group companies were used in the analysis, as well as other market data. Radford's review demonstrated that our average annual cash compensation for non-employee directors trailed the 50 th  percentile for our peer group companies while the average equity compensation value was between the 25 th  and 50 th  percentile. In order to better align non-employee director compensation to our peer group, the board of directors, at the recommendation of the compensation committee, adopted the following changes as of the date of the 2011 annual meeting of stockholders based on Radford's analysis and recommendations:

Our current compensation for non-employee directors consists of:

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Compensation Paid to Directors and Executive Officers

        Please see discussion under the heading "Executive Compensation."

Registration Rights

        For information relating to certain registration rights granted by us to a certain stockholder, please see the discussion under the heading "Compensation Committee Interlocks and Insider Participation."


POLICIES AND PROCEDURES FOR RELATED PERSON TRANSACTIONS

        Our board of directors has adopted written policies and procedures for the review of any transaction, arrangement or relationship in which we are a participant, the amount involved exceeds $120,000, and one of our executive officers, directors, director nominees or 5% stockholders (or their immediate family members), each of whom we refer to as a "related person," has a direct or indirect material interest.

        If a related person proposes to enter into such a transaction, arrangement or relationship, which we refer to as a "related person transaction," the related person must report the proposed related person transaction to our General Counsel. The policy calls for the proposed related person transaction to be reviewed and, if deemed appropriate, approved by our audit committee. Whenever practicable, the reporting, review and approval will occur prior to entry into the transaction. If advance review and approval is not practicable, the audit committee will review, and, in its discretion, may ratify the related person transaction. The policy also permits the chairman of the audit committee to review and, if deemed appropriate, approve proposed related person transactions that arise between committee meetings, subject to ratification by the audit committee at its next meeting. Any related person transactions that are ongoing in nature will be reviewed annually.

50


        A related person transaction reviewed under the policy will be considered approved or ratified if it is authorized by the audit committee after full disclosure of the related person's interest in the transaction. As appropriate for the circumstances, the audit committee will review and consider:

        Our audit committee may approve or ratify the transaction only if the audit committee determines that, under all of the circumstances, the transaction is in our best interests. Our audit committee may impose any conditions on the related person transaction that it deems appropriate.

        In addition to the transactions that are excluded by the instructions to the Securities and Exchange Commission's related person transaction disclosure rule, our board of directors has determined that the following transactions do not create a material direct or indirect interest on behalf of related persons and, therefore, are not related person transactions for purposes of this policy:

        The policy provides that transactions involving compensation of executive officers shall be reviewed and approved by our compensation committee in the manner specified in its charter.

        We will disclose the terms of related person transactions in our filings with the Securities and Exchange Commission to the extent required. Since January 1, 2010, we have not been a party to, and we have no plans to be a party to, any transaction or series of similar transactions in which the amount involved exceeded or will exceed $120,000 and in which any current director, executive officer, holder of more than 5% of our capital stock, or any member of the immediate family of any of the foregoing, had or will have a direct or indirect material interest, other than in connection with the transactions described above.

Representatives of Ernst & Young LLP are expected to be present at the Annual Meeting and will have the opportunity to make a statement, if they desire to do so, and will be available to respond to appropriate questions from our stockholders.

Our independent registered public accounting firm is responsible for conducting an independent audit of our annual consolidated financial statements in accordance with generally accepted auditing standards and issuing a report on the results of their audit. The audit committee is responsible for providing independent, objective oversight of these processes.

        The audit committee has also received from, and discussed with, our independent registered public accounting firm various communications that they are required to provide to the audit committee, including the matters required to be discussed by Statement on Auditing Standards No. 61, as amended (AICPA, Professional Standards , Vol. 1, AU section 380), as adopted by the Public Company Accounting Oversight Board in Rule 3200T.

        Our independent registered public accounting firm also provided the audit committee with the written disclosures and letter required by applicable requirements of the Public Company Accounting Oversight Board regarding the independent accountant's communications with the audit committee concerning independence, and our audit committee has discussed with our independent registered public accounting firm their independence.

        Based on the review and discussions referred to above, the audit committee recommended to our board of directors that the audited consolidated financial statements be included in our Annual Report on Form 10-K for the year ended December 31, 2010 for filing with the Securities and Exchange Commission.

PROPOSAL THREE

ADVISORY VOTE ON EXECUTIVE COMPENSATION

        The recently enacted Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, or the Dodd-Frank Act, enables our stockholders to vote to approve, on a non-binding advisory basis, the compensation of our Named Executives as disclosed in this proxy statement in accordance with applicable SEC rules. This vote, commonly known as a "say-on-pay" vote, provides stockholders with the opportunity to express their views on our named executives' compensation and is required by Section 14A of the Exchange Act. The vote is not intended to address any specific item of our executive compensation, but rather the overall compensation of our Named Executives and the philosophy, policies and practices described in this proxy statement. Section 14A of the Exchange Act also requires that stockholders have the opportunity to cast a non-binding advisory vote with respect to whether future non-binding advisory votes on executive compensation will be held every one, two or three years, which is the subject of Proposal Four.

        As described in the section of this proxy statement entitled "Executive Compensation" beginning on page 25, including "Compensation Discussion and Analysis" and related compensation tables, our executive compensation program is designed to attract, retain, and motivate talented individuals with the executive experience and leadership skills necessary for us to increase stockholder value. We seek to provide executive compensation that is competitive with companies that are similar to us. We also seek to provide near-term and long-term financial incentives that reward executives when strategic corporate objectives designed to increase long-term stockholder value are achieved. We believe that executive compensation should include base salary, cash incentives and equity awards. We also believe that our executive officers' base salaries should be set at approximately median levels relative to comparable companies, and cash and equity incentives should generally be set at levels that give executives the opportunity to achieve above-average total compensation reflecting above-average company performance. In particular, our executive compensation philosophy is to promote long-term value creation for our shareholders by rewarding improvement in selected financial metrics, and by using equity incentives. Please see the "Executive Compensation" section of this proxy statement, including the "Compensation Discussion and Analysis" and related compensation tables for detailed information about our executive compensation programs, including information about the compensation of our Named Executives for the fiscal year ended December 31, 2010.

        Our board of directors is asking stockholders to approve a non-binding advisory vote on the following resolution:

        RESOLVED, that the compensation paid to our Named Executives, as disclosed pursuant to the compensation disclosure rules of the Securities and Exchange Commission, including the compensation discussion and analysis, the compensation tables and any related material disclosed in this proxy statement, is hereby approved.

        The say-on-pay vote is advisory, and therefore not binding on us, our board of directors, or the compensation committee of the board of directors. However, our board of directors and compensation committee value the opinions of our stockholders and to the extent there is any significant vote against the Named Executive compensation as disclosed in this proxy statement, we will consider our stockholders' concerns and the compensation committee will evaluate whether any actions are necessary to address those concerns.

Board Recommendation

         The board of directors recommends a vote FOR the approval of the compensation of our named executives as disclosed in this proxy statement.

54



PROPOSAL FOUR

FREQUENCY OF VOTE ON EXECUTIVE COMPENSATION

        The Dodd-Frank Act also enables stockholders to indicate on a non-binding advisory basis how frequently they would like us to conduct non-binding advisory stockholder votes on our executive compensation. Stockholders have the opportunity to indicate whether they prefer a non-binding advisory vote on executive officer compensation every one, two or three years.

        The vote with respect to the frequency of the non-binding advisory vote on the compensation of our Named Executives is not binding on us or our board of directors. However, our board will take the results of the vote into consideration when deciding when to call for the next non-binding advisory vote on the compensation of our Named Executives. A frequency vote similar to this will occur at least once every six years.

        After careful consideration of the frequency alternatives, the board of directors believes that conducting a non-binding advisory vote on executive compensation every one year is appropriate for us and our stockholders at this time. The board of directors believes that an annual executive compensation advisory vote will facilitate more direct stockholder input about executive compensation. An annual executive compensation advisory vote is consistent with our policy of reviewing our compensation program annually, as well as seeking frequent input from our stockholders on corporate governance and executive compensation matters. We believe an annual vote would be the best governance practice for us at this time.

Board Recommendation

         The board of directors recommends voting for a frequency of every ONE YEAR for the frequency with which stockholders will be asked to cast a non-binding advisory vote on the compensation of our Named Executives.

55



STOCKHOLDER PROPOSALS

        In order to be included in proxy material for the 2012 annual meeting of stockholders pursuant to Rule 14a-8 under the Securities and Exchange Act of 1934, as amended, stockholders' proposals must be received by us at our principal executive offices, 675 West Kendall Street, Cambridge, Massachusetts 02142, no later than December 28, 2011. We suggest that proponents submit their proposals by certified mail, return receipt requested, addressed to our Secretary, Bruce A. Leicher, Esq.

        Stockholders who intend to present a proposal at such meeting without inclusion of such proposal in our proxy materials pursuant to Rule 14a-8 under the Securities Exchange Act of 1934, as amended, are required to provide advanced notice of such proposal to us at the aforementioned address not later than March 10, 2012.

        In addition, our by-laws require that we be given advance notice of stockholder nominations for election to the board of directors and of other matters which stockholders wish to present for action at an annual meeting of stockholders, other than matters included in our proxy statement. The required notice must be in writing and received by our Secretary at our principal offices not later than 90 days prior to the first anniversary of the preceding year's annual meeting and not before 120 days prior to the first anniversary of the preceding year's annual meeting. However, if the 2011 annual meeting of stockholders is advanced by more than 20 days, or delayed by more than 60 days, from the first anniversary of the Annual Meeting, notice must be received not earlier than the 120th day prior to such annual meeting and not later than the close of business on the later of (1) the 90th day prior to such annual meeting and (2) the 10th day following the date on which notice of the date of such annual meeting was mailed or public disclosure of the date of such annual meeting was made, whichever occurs first. Our by-laws also specify requirements relating to the content of the notice that stockholders must provide, including a stockholder nomination for election to the board of directors, to be properly presented at the 2011 annual meeting of stockholders.


HOUSEHOLDING OF ANNUAL MEETING MATERIALS

        Some banks, brokers and other nominee record holders may be participating in the practice of "householding" proxy statements and annual reports. This means that only one copy of our proxy statement and annual report to stockholders may have been sent to multiple stockholders in your household. We will promptly deliver a separate copy of either document to you upon written request to Momenta Pharmaceuticals, Inc., 675 West Kendall Street, Cambridge, Massachusetts 02142, Attention: Richard P. Shea, Chief Financial Officer and Treasurer, facsimile: (617) 621-0431. If you want to receive separate copies of the proxy statement or annual report to stockholders in the future, or if you are receiving multiple copies and would like to receive only one copy per household, you should contact your bank, broker or other nominee record holder, or you may contact us at the above address and phone number.


OTHER MATTERS

        Our board of directors is not aware of any matter to be presented for action at the Annual Meeting other than the matters referred to above and does not intend to bring any other matters before the Annual Meeting. However, if other matters should properly come before the Annual Meeting, it is intended that holders of the proxies will vote thereon in their discretion.

56
