Corporate Governance Guidelines

The Board of Directors (the "Board") of NxStage Medical, Inc. (the "Company") has adopted the following Corporate Governance Guidelines (the "Guidelines") to assist the Board in the exercise of its duties and responsibilities and to serve the best interests of the Company and its stockholders. The Guidelines should be applied in a manner consistent with all applicable laws and the Company's charter and bylaws, each as amended and in effect from time to time. The Guidelines provide a framework for the conduct of the Board's business. The Board may modify or make exceptions to the Guidelines from time to time in its discretion and consistent with its duties and responsibilities to the Company and its stockholders.




1. Oversee Management of the Company. The principal responsibility of the directors is to oversee the management of the Company and, in so doing, serve the best interests of the Company and its stockholders. This responsibility includes:

  • Reviewing and approving fundamental operating, financial and other corporate plans, strategies and objectives.
  • Assessing major risks facing the Company and reviewing options for their mitigation.
  • Requiring, approving and implementing senior executive succession plans.
  • Establishing a corporate environment that promotes timely and effective disclosure (including robust and appropriate controls, procedures and incentives), fiscal accountability, high ethical standards and compliance with all applicable laws and regulations.
  • Reviewing and approving material transactions and commitments not entered into in the ordinary course of business.
  • Developing a corporate governance structure that allows and encourages the Board to fulfill its responsibilities.
  • Providing advice and assistance to the Company's senior executives.
  • Providing counsel and oversight on the selection, evaluation, development and compensation of executive officers and providing critical and candid feedback on their successes and failures;
  • Evaluating the overall effectiveness of the Board and its committees.

2. Exercise Business Judgment. In discharging their fiduciary duties of care, loyalty and candor, directors are expected to exercise their business judgment to act in what they reasonably believe to be the best interests of the Company and its stockholders.

3. Understand the Company and its Business. Directors have an obligation to become and remain informed about the Company and its business, including the following:

  • The principal operational and financial objectives, strategies and plans of the Company.
  • The results of operations and financial condition of the Company and of significant subsidiaries.
  • The relative standing of the Company's business vis-à-vis competitors.
  • The factors that determine the Company's success.
  • The risks and problems that affect the Company's business and prospects.

4. Establish Effective Systems. Directors are responsible for determining that effective systems are in place to ensure the periodic and timely reporting to the Board of important matters concerning the Company, including the following:

  • Current business and financial performance, the degree of achievement of approved objectives and the need to address forward-planning issues.
  • Future business prospects and forecasts, including actions, facilities, personnel and financial resources required to achieve forecasted results.
  • Financial statements.
  • Assessing major risks facing the Company.
  • Compliance programs to assure the Company's compliance with law and corporate policies.
  • Material litigation and governmental and regulatory matters.
  • Monitoring and, where appropriate, responding to communications from stockholders.

        Directors should also periodically review the integrity of the Company's internal control and information management                  systems.

5. Board, Stockholder and Committee Meetings. Directors are responsible for attending Board meetings, meetings of committees on which they serve and the annual meeting of stockholders, and devoting the time needed, and meeting as frequently as necessary, to discharge their responsibilities properly.

6. Reliance on Management and Advisors; Indemnification. The directors are entitled to rely on the Company's senior executives and its outside advisors, auditors and legal counsel, except to the extent that any such person's integrity, honesty or competence is in doubt. The directors are also entitled to Company-provided indemnification, statutory exculpation and directors' and officers' liability insurance.

1. Independence. Except as may otherwise be permitted by NASDAQ rules, a majority of the members of the Board shall be independent directors. To be considered independent: (1) a director must be “independent” as determined under the applicable provisions of the Company’s bylaws, the Securities Exchange Act of 1934, as amended, and NASDAQ rules and (2) in the Board’s judgment, the director must not have a relationship with the Company that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Because it is not possible to anticipate all potential situations that may affect independence, the Nominating and Corporate Governance Committee will periodically review each director’s status as an independent director and whether any independent director has any other relationship with the Company that, in the judgment of the Nominating and Corporate Governance Committee, would interfere with the director’s exercise of independent judgment in carrying out such director’s responsibilities as director. The Nominating and Corporate Governance Committee will make an annual determination and recommendation to the Board regarding each director’s eligibility to be classified as “independent” for purposes of serving on the Board and on each of the Board’s committees.

2. Size of the Board. The size of the Board is currently set at eight members. The Board believes this is an appropriate size given the Company's present circumstances, but that a smaller or larger Board may be appropriate at any given time, depending on circumstances and changes in the Company's business.

3. Other Directorships. No Board member shall serve on the board of directors of more than five public companies.  Directors should advise the Chair of the Nominating and Corporate Governance Committee and Chief Executive Officer before accepting membership on other public company boards of directors.  The Nominating and Corporate Governance Committee shall take into account the nature of the time involved in a director's service on other boards in evaluating the suitability of individual directors and making its recommendations to the Board. In addition, no member of the Audit Committee shall serve simultaneously on the Audit Committees of more than three public companies without a specific Board determination that such simultaneous service will not impair the ability of such Audit Committee member to serve on the Audit Committee.

4. Tenure. The Board does not believe it should establish term limits. Term limits could result in the loss of directors who have been able to develop, over a period of time, increasing insight into the Company and its operations and an institutional memory that benefit the entire membership of the Board as well as management. As an alternative to term limits, the Nominating and Corporate Governance Committee shall review each director's continuation on the Board at least once every three years. This will allow each director the opportunity to conveniently confirm his or her desire to continue as a member of the Board and allow the Company to conveniently replace directors who are no longer interested or effective.

5. Retirement Age. The Board has established a retirement age of 72 for all Board members. Once a Board member reaches that age, he or she shall retire from the Board at the end of his or her then-current term, provided that the Nominating and Corporate Governance Committee can extend this age for such director in its sole discretion.

6. Change in Job Responsibility.It is the sense of the Board that when a Director's principal occupation or business association changes substantially from the position he or she held when originally invited to join the Board, the Director will tender a letter of resignation to the Nominating and Corporate Governance Committee. Such Committee will review whether the change in occupation or business association of the Director is consistent with the specific rationale for originally selecting that individual and the guidelines for Board membership. The Committee will recommend action to be taken regarding the resignation based on the circumstances of the retirement or termination of occupation or business association, if that is the case, or in the case of a new position, the responsibility and type of position, and industry involved. The bias of the Committee will be to accept the resignation if the basis for originally selecting the individual no longer exists.

7. Separation of the Offices of Chairman and Chief Executive Officer. The offices of the Chairman of the Board and Chief Executive Officer must be separate.

8. Selection of New Director Candidates. Except where the Company is legally required by contract, bylaw or otherwise to provide third parties with the right to nominate directors, the Nominating and Corporate Governance Committee shall be responsible for (i) identifying individuals qualified to become Board members, consistent with criteria approved by the Board, and (ii) recommending to the Board the persons to be nominated for election as directors at any meeting of stockholders and the persons to be elected by the Board to fill any vacancies on the Board. Director nominees shall be considered for recommendation by the Nominating and Corporate Governance Committee in accordance with the criteria and principles in its charter and the criteria set forth in Attachment A to these Guidelines. It is expected that the Nominating and Corporate Governance Committee will have direct input from the Chairman of the Board and the Chief Executive Officer.

9. Extending the Invitation to a New Director Candidate to Join the Board. The invitation to join the Board should be extended by the Chairman of the Board, on behalf of the Board, and the Chairman of the Nominating and Corporate Governance Committee, on behalf of such Committee. Unauthorized approaches to prospective directors can be premature, embarrassing and harmful.

10. Former Chief Executive Officer's Board Membership. The Board believes that the continuation of a former Chief Executive Officer of the Company on the Board is a matter to be decided in each individual instance by the Board, upon recommendation of the Nominating and Corporate Governance Committee. Accordingly, when the Chief Executive Officer ceases to serve in that position, he or she will be expected to resign from the Board if so requested by the Board, upon recommendation of the Nominating and Corporate Governance Committee.

1. Selection of Agenda Items. The Chairman of the Board shall work with the Chief Executive Officer to develop an agenda for each Board meeting. Each Board member is free to suggest the inclusion of agenda items and is free to raise at any Board meeting subjects that are not on the agenda for that meeting.

2. Frequency and Length of Meetings. The Chairman of the Board, in consultation with the members of the Board, shall determine the frequency and length of the Board meetings. Special meetings may be called from time to time as determined by the needs of the business.

3. Advance Distribution of Materials. Information and data that are important to the Board's understanding of the business to be conducted at a Board or committee meeting should generally be distributed in writing to the directors before the meeting, and directors should review these materials in advance of the meeting. The Board acknowledges that certain items to be discussed at a Board or committee meeting may be of an extremely confidential or time-sensitive nature and that the distribution of materials on these matters prior to meetings may not be appropriate or practicable. Presentations made at Board meetings should do more than summarize previously distributed Board meeting materials.

4. Executive Sessions. The independent directors shall meet in executive session at least twice a year to discuss, among other matters, the performance of the Chief Executive Officer. The non-management directors will meet in executive session at other times at the request of any non-management director. Absent unusual circumstances, these sessions shall be held in conjunction with regular Board meetings. The director who presides at these meetings shall be the Chairman of the Board.

5. Attendance of Non-Directors at Board Meetings. The Board encourages the senior executives of the Company to, from time to time, bring Company personnel into Board meetings who (i) can provide additional insight into the items being discussed because of personal involvement in these areas or (ii) appear to be persons with future potential who should be given exposure to the Board.

1. Key Committees. The Board shall have at all times an Audit Committee, a Compensation Committee and a Nominating and Corporate Governance Committee. Each such committee shall have a charter that has been approved by the Board. The Board may, from time to time, establish or maintain additional committees as necessary or appropriate.

2. Assignment and Rotation of Committee Members. The Nominating and Corporate Governance Committee shall be responsible for recommending to the Board the directors to be appointed to each committee of the Board, and the Board is responsible for the appointment of committee members. In addition to any other applicable requirements of independence, each member of the Audit Committee, the Compensation Committee and the Nominating and Corporate Governance Committee shall be an "independent director" as defined by NASDAQ Stock Market Rule 4200 (a) (15).

3. Committee Charters. In accordance with applicable NASDAQ rules, the charters of the Audit Committee, the Compensation Committee and the Nominating and Corporate Governance Committee shall set forth the purposes and responsibilities of the committees as well as qualifications for committee membership, procedures for committee member appointment and removal, committee structure and operations and committee reporting to the Board. The Board shall, from time to time as it deems appropriate, review and reassess the adequacy of each charter and make appropriate changes.

4. Selection of Agenda Items. The chairman of each committee, in consultation with the committee members, shall develop the committee's agenda. At the beginning of the year each committee shall establish a schedule of subjects to be discussed during the year (to the extent practicable). The schedule for each committee meeting shall be furnished to all directors.

5. Frequency and Length of Committee Meetings. The chairman of each committee, in consultation with the committee members, shall determine the frequency and length of the committee meetings consistent with any requirements set forth in the committee's charter. Special meetings may be called from time to time as determined by the needs of the business and the responsibilities of the committees.

1. Access to Officers and Employees. Directors have full and free access to officers and employees of the Company. Any meetings or contacts that a director wishes to initiate may be arranged through the Chief Executive Officer or directly by the director. The directors shall use their judgment to ensure that any such contact is not disruptive to the business operations of the Company and shall, to the extent appropriate, copy the Chief Executive Officer on any written communications between a director and an officer or employee of the Company.

2. Access to Independent Advisors. The Board and each committee have the power to hire and consult with independent financial, legal or other advisors for the benefit of the Board or such committee, as they may deem necessary, without consulting or obtaining the approval of any officer of the Company in advance. Such independent advisors may be the regular advisors to the Company. The Board or any such committee is empowered, without further action by the Company, to cause the Company to pay the compensation of such advisors as established by the Board or any such committee.

1. Role of Board and Compensation Committee. The form and amount of director compensation shall be determined by the Board in accordance with the policies and principles set forth below. The Compensation Committee shall conduct a periodic (but at least annual) review of the compensation of the Company's directors. The Compensation Committee shall consider that questions as to directors' independence may be raised if director compensation and perquisites exceed customary levels, if the Company makes substantial charitable contributions to organizations with which a director is affiliated or if the Company enters into consulting contracts or business arrangements with (or provides other indirect forms of compensation to) a director or an organization with which the director is affiliated.

2. Form of Compensation. The Board believes that directors should be incentivized to focus on long-term stockholder value. To create a direct link with corporate performance and to align the interests of directors with that of stockholders, the Board believes that a meaningful portion of the total compensation of non-employee directors should be provided and held in the form of Company common stock, stock options, restricted stock or other types of equity-based compensation.

3. Amount of Consideration. The Company seeks to attract exceptional talent to its Board. Therefore, the Company's policy is to compensate directors at least competitively relative to comparable companies. The Company's management shall, from time to time, present a comparison report to the Board, comparing the Company's director compensation with that of comparable companies. The Board believes that it is appropriate for the Chairman of the Board and the Chair and members of the committees to receive additional compensation for their services in those positions.

4. Employee Directors. Directors who are also employees of the Company or its affiliates shall receive no additional compensation for Board or committee service.

The Board and the Company's management shall conduct a mandatory orientation program for new directors. The orientation program shall include presentations by management to familiarize new directors with the Company's strategic plans, its significant financial, accounting and risk management issues, its compliance programs, its code of business conduct and ethics, its principal officers, its internal and independent auditors and its outside legal advisors. In addition, the orientation program shall include a review of the Company's expectations of its directors in terms of time and effort, a review of the directors' fiduciary duties and visits to Company headquarters and, to the extent practical, certain of the Company's significant facilities. All other directors are also invited to attend the orientation program.

The Board also recognizes the importance of continuing education for its directors and is committed to provide such education in order to improve both Board and committee performance. The Board acknowledges that director continuing education may be provided in a variety of different forms, including external or internal education programs, presentations or briefings on particular topics, educational materials, meetings with key management and visits to the Company's facilities. Board members are also encouraged to attend seminars, conferences, and other continuing education programs designed especially for directors of public companies, including, specifically, accredited director education programs.

1. Selection of Chief Executive Officer. The The Board selects the Company's Chief Executive Officer in the manner that it determines to be in the best interests of the Company's stockholders.

2. Evaluation of Senior Executives. The Compensation Committee shall review and approve, or recommend for approval by the Board, the compensation of the Company's Chief Executive Officer and the Company's other executive officers. The Compensation Committee shall also be responsible for overseeing the evaluation of the Company's senior executives. In conjunction with the Audit Committee in the case of the evaluation of the Chief Financial Officer, the Compensation Committee shall determine the nature and frequency of the evaluation and the persons subject to the evaluation, supervise the conduct of the evaluation and prepare assessments of the performance of the Company's senior executives, to be discussed with the Board periodically. The Board shall review the assessments to ensure that the senior executives are providing the best leadership for the Company over both the long- and short-term.

3. Succession of Senior Executives. The Compensation Committee shall be responsible for overseeing an annual evaluation of succession planning.

The Nominating and Corporate Governance Committee shall oversee an annual self-evaluation of the Board to determine whether it and its committees are functioning effectively. The Nominating and Corporate Governance Committee shall determine the nature of the evaluation, which will include individual director assessments, supervise the conduct of the evaluation and prepare an assessment of the Board’s performance, to be discussed with the Board. The purpose of this process is to improve the effectiveness of the Board and its committees and not to target individual Board members.

The Board believes that the Chief Executive Officer and his or her designees speak for the Company. Individual Board members may, from time to time, meet or otherwise communicate with various constituencies that are involved with the Company. It is, however, expected that Board members would do so with the knowledge of and, absent unusual circumstances or as contemplated by the committee charters, only at the request of the Company's senior executives.

The Board will give appropriate attention to written communications that are submitted by stockholders and other interested parties, and will respond if and as appropriate. Absent unusual circumstances or as contemplated by the committee charters, the Chairman of the Board shall, subject to advice and assistance from the General Counsel, (1) be primarily responsible for monitoring communications from shareholders and other interested parties, and (2) provide copies or summaries of such communications to the other directors as he or she considers appropriate.

The Board plays an active role, at both the Board and committee levels, in overseeing risk management. The Board regularly reviews information provided by Company management regarding the Company’s liquidity, operations and compliance program, including conformity with its code of business conduct and ethics, as well as the risks associated with each. The Compensation Committee is responsible for overseeing the management of risks relating to the Company’s executive compensation plans and arrangements. The Audit Committee oversees management of risks relating to financial reporting, internal controls and information security. The Nominating and Corporate Governance Committee oversees the management of risks associated with corporate governance, the independence of the Board and potential conflicts of interest. While each committee is responsible for evaluating certain risks and overseeing the management of such risks, the entire Board is regularly informed through committee reports about such risks..

The Nominating and Corporate Governance Committee shall, from time to time as it deems appropriate, review and reassess the adequacy of these Guidelines and recommend any proposed changes to the Board for approval.
