How Our Board Is Organized

Board Leadership Structure

Our board of directors, upon the recommendation of our corporate governance and nominating committee, has determined that the roles of Chairman of the Board and Chief Executive Officer should be separated at the current time. Accordingly, our board has appointed Mr. Crocker, an independent director within the meaning of Nasdaq Listing Rules, as the Chairman of the Board.

Mr. Crocker’s duties as Chairman of the Board include the following:

 

   

chairing meetings of our board and of the independent directors in executive session;

 

   

meeting with any director who is not adequately performing his or her duties as a member of our board or any committee;

 

   

facilitating communications between other members of our board and the Chief Executive Officer;

 

   

determining the frequency and length of board meetings and recommending when special meetings of our board should be held;

 

   

preparing or approving the agenda for each board meeting; and

 

   

reviewing and, if appropriate, recommending action to be taken with respect to written communications from stockholders submitted to our board.

Our board of directors decided to separate the roles of Chairman of the Board and Chief Executive Officer because it believes that a bifurcated leadership structure offers the following benefits:

 

   

increasing the independent oversight of Merrimack and enhancing our board’s objective evaluation of the Chief Executive Officer;

 

   

freeing the Chief Executive Officer to focus on company operations instead of board administration;

 

   

providing the Chief Executive Officer with an experienced sounding board;

 

   

providing greater opportunities for communication between stockholders and our board;

 

   

enhancing the independent and objective assessment of risk by our board; and

 

   

providing an independent spokesman for Merrimack.

Board Committees

Our board of directors has established an audit committee, a corporate governance and nominating committee and an organization and compensation committee, each of which operates under a charter that has been approved by our board. Copies of the committee charters are posted on the Investors section of our website, which is located at investors.merrimack.com. We are not including the information contained on our website as a part of, or incorporating it by reference into, this Amendment.

Audit Committee

The members of our audit committee are Dr. Nielsen, Mr. Quigley and Mr. Ray. Mr. Quigley chairs the audit committee. Our audit committee’s responsibilities include:

 

   

appointing, approving the compensation of and assessing the independence of our registered public accounting firm;

 

   

overseeing the work of our independent registered public accounting firm, including through the receipt and consideration of reports and other communications from such firm;

 

   

reviewing and discussing with management and the independent registered public accounting firm our annual and quarterly financial statements and related disclosures;

 

   

monitoring our internal control over financial reporting, disclosure controls and procedures and code of business conduct and ethics;

 

   

overseeing our internal audit function;

 

   

overseeing our risk assessment and risk management policies;

Table of Contents
   

establishing policies regarding hiring employees from the independent registered public accounting firm and procedures for the receipt and retention of accounting-related complaints and concerns;

 

   

meeting independently with our internal auditors, independent registered public accounting firm and management;

 

   

reviewing and approving or ratifying any related person transactions; and

 

   

preparing the audit committee report required by SEC rules.

All audit and non-audit services, other than de minimis non-audit services, to be provided to us by our independent registered public accounting firm must be approved in advance by our audit committee.

Our board of directors has determined that Mr. Quigley is an “audit committee financial expert” as defined in applicable SEC rules. We believe that the composition of our audit committee meets the requirements for independence under the current Nasdaq Listing Rules and SEC rules and regulations.

The audit committee met five times during 2018.

Corporate Governance and Nominating Committee

The members of our corporate governance and nominating committee are Mr. Crocker and Dr. Nielsen. Mr. Crocker chairs the corporate governance and nominating committee. Our corporate governance and nominating committee’s responsibilities include:

 

   

identifying individuals qualified to become members of our board;

 

   

recommending to our board the persons to be nominated for election as directors and to each of our board’s committees;

 

   

reviewing and making recommendations to our board with respect to our board leadership structure;

 

   

developing and recommending to our board corporate governance principles; and

 

   

overseeing an annual evaluation of our board.

The corporate governance and nominating committee met once during 2018.

Organization and Compensation Committee

The members of our organization and compensation committee are Dr. Demetri, Mr. Dineen and Mr. Ray. Mr. Dineen chairs the organization and compensation committee. Our organization and compensation committee’s responsibilities include:

 

   

reviewing and making recommendations to our board with respect to our Chief Executive Officer’s compensation;

 

   

reviewing and approving, or making recommendations to our board with respect to, the compensation of our other executive officers;

 

   

overseeing an evaluation of our executive officers;

 

   

overseeing and administering our cash and equity incentive plans;

 

   

reviewing and making recommendations to our board with respect to director compensation; and

 

   

reviewing and making recommendations to our board with respect to management succession planning.

The processes and procedures followed by our organization and compensation committee in considering and determining executive and director compensation are described below under “Executive and Director Compensation Processes.”

The organization and compensation committee met ten times during 2018.

Board Meetings and Attendance

Our board of directors met eleven times during 2018. During 2018, each director attended at least 75% of the aggregate of the number of board meetings and the number of meetings held by all committees of our board on which he then served.

Our directors are encouraged to attend our annual meetings of stockholders. Four of our nine directors then serving attended our 2018 Annual Meeting of Stockholders.

Board Processes

Oversight of Risk

Our board oversees our risk management processes directly and through its committees. Our management is responsible for risk management on a day-to-day basis. The role of our board and its committees is to oversee the risk management activities of management. They fulfill this duty by discussing with management the policies and practices utilized by management in assessing and managing risks and providing input on those policies and practices. In general, our board oversees risk management activities relating to business strategy, acquisitions, capital allocation, organizational structure and certain operational risks; our audit committee oversees risk management activities related to financial controls and legal and compliance risks; our corporate governance and nominating committee oversees risk management activities relating to board composition; and our organization and compensation committee oversees risk management activities relating to our compensation policies and practices and management succession planning. Each committee reports to the full board on a regular basis, including reports with respect to the committee’s risk oversight activities as appropriate. In addition, since risk issues often overlap, committees from time to time request that that the full board discuss particular risks.

Director Nomination Process

The process followed by our corporate governance and nominating committee to identify and evaluate director candidates may include requests to board members and others for recommendations, evaluation of the performance on our board and its committees of any existing directors being considered for nomination, consideration of biographical information and background material relating to potential candidates and, particularly in the case of potential candidates who are not then serving on our board, interviews of selected candidates by members of the committee and our board.

In considering whether to recommend any particular candidate for inclusion in our board’s slate of recommended director nominees, our corporate governance and nominating committee applies the criteria set forth in our corporate governance guidelines. Consistent with these criteria, our corporate governance and nominating committee expects every nominee to have the following attributes or characteristics, among others: integrity, honesty, adherence to high ethical standards, business acumen, good judgment and a commitment to understand our business and industry.

Our corporate governance and nominating committee considers the value of diversity when selecting nominees, and believes that our board, taken as a whole, should embody a diverse set of skills, experiences and backgrounds. The committee does not make any particular weighting of diversity or any other characteristic in evaluating nominees and directors.

Stockholders may recommend individuals for consideration as potential director candidates by submitting their names, together with appropriate biographical information and background materials, and information with respect to the stockholder or group of stockholders making the recommendation, including the number of shares of common stock owned by such stockholder or group of stockholders, to our Corporate Secretary at Merrimack Pharmaceuticals, Inc., One Kendall Square, Suite B7201, Cambridge, Massachusetts 02139, Attention: Corporate Secretary. The specific requirements for the information that is required to be provided for such recommendations to be considered are specified in our bylaws. Assuming that appropriate biographical and background material has been provided on a timely basis, the corporate governance and nominating 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.

Executive and Director Compensation Processes

Our executive compensation program is administered by the organization and compensation committee of our board of directors, subject to the oversight and approval of our full board of directors. Our organization and compensation committee reviews our executive compensation practices on an annual basis and based on this review makes recommendations to our board of directors for approval, which has full discretion to approve or modify the recommendations of the organization and compensation committee.

In designing our executive compensation program, our organization and compensation committee considers publicly available compensation data for national and regional companies in the biotechnology/pharmaceutical industry to help guide its executive compensation decisions at the time of hiring and for subsequent adjustments in compensation. The organization and compensation committee is directly responsible for the appointment and oversight of any compensation consultants and other advisors it retains.

Our director compensation program is administered by our board of directors with the assistance of the organization and compensation committee. The organization and compensation committee periodically reviews director compensation and makes recommendations to our board with respect thereto.

Communications with Stockholders

Our management will give appropriate attention to written communications that are submitted by stockholders, and will respond if and as appropriate. Stockholders may communicate with our management by writing to our Corporate Secretary at Merrimack Pharmaceuticals, Inc., One Kendall Square, Suite B7201, Cambridge, Massachusetts 02139, Attention: Corporate Secretary, or by calling (617) 441-1000. Additional information about contacting Merrimack is available on the Investors section of our website, which is located at investors.merrimack.com.

In addition, stockholders who wish to communicate with our entire board may do so by writing to Gary L. Crocker, Chairman of the Board, Merrimack Pharmaceuticals, Inc., One Kendall Square, Suite B7201, Cambridge, Massachusetts 02139. Communications will be forwarded to other directors if they relate to substantive matters that the Chairman of the Board, in consultation with our General Counsel, considers appropriate for attention by the other directors. In general, communications relating to corporate governance and long-term corporate strategy are more likely to be forwarded than communications relating to ordinary business affairs, personal grievances or matters as to which we tend to receive repetitive or duplicative communications.

Corporate Governance Guidelines

Our board of directors has adopted corporate governance guidelines to assist in the exercise of its duties and responsibilities and to serve the best interests of Merrimack and our stockholders. The guidelines provide that:

 

   

our board’s principal responsibility is to oversee the management of Merrimack;

 

   

a majority of the members of our board must be independent directors;

 

   

the independent directors meet in executive session at least twice a year;

 

   

directors have full and free access to management and, as necessary, independent advisors;

 

   

new directors participate in an orientation program and all directors are expected to participate in continuing director education on an ongoing basis; and

 

   

our board will conduct an annual self-evaluation to determine whether it and its committees are functioning effectively.

A copy of the corporate governance guidelines is posted on the Investors section of our website, which is located at investors.merrimack.com.

Family Relationships

There are no family relationships among any of our directors or executive officers.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Exchange Act requires our directors, executive officers and holders of more than 10% of our common stock to file with the SEC 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. Directors, executive officers and holders of more than 10% of our common stock are required by SEC regulations to furnish us with copies of all Section 16(a) forms they file. Based solely on a review of our records and representations made by the persons required to file these reports, we believe that, during the year ended December 31, 2018, our directors, executive officers and holders of more than 10% of our common stock complied with all Section 16(a) filing requirements applicable to them.

Code of Business Conduct and Ethics

Our board of directors has 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. A copy of the code of business conduct and ethics is posted on the Investors section of our website, which is located at investors.merrimack.com. In addition, we intend to post on our website all disclosures that are required by law or the Nasdaq Listing Rules concerning any amendments to, or waivers from, any provision of our code of business conduct and ethics.

Narrative to Summary Compensation Table

We use base salaries to recognize the experience, skills, knowledge and responsibilities of our employees, including our named executive officers. None of our named executive officers is currently party to an employment agreement that provides for automatic or scheduled increases in base salary.

For 2018, each named executive officer was eligible to receive an annual performance-based cash bonus (“annual cash bonus”) with a target amount equal to a fixed percentage of his or her base salary (“bonus percentage”). Dr. Peters’ target annual cash bonus for 2018 was 65% of his 2018 base salary and was based solely on the achievement of our corporate objectives. Ms. Franchi’s and Dr. Santillana’s target annual cash bonuses for 2018 were 35% of her or his respective 2018 base salary and were based 80% on the achievement of our corporate objectives and 20% on the achievement of specified individual objectives. The board of directors determined retroactively at what level we had achieved our corporate objectives for 2018, and the organization and compensation committee determined retroactively at what level Ms. Franchi and Dr. Santillana had achieved her or his respective individual objectives for 2018.

Our equity award program is the primary vehicle for offering long-term incentives to our named executive officers. While we do not currently have any equity ownership guidelines for our named executive officers, we believe that equity grants provide our named executive officers with a strong link to our long-term performance, create an ownership culture and help to align the interests of our named executive officers and our stockholders. Typically, the stock options we grant to our named executive officers vest quarterly over a three year period. Vesting and exercise rights cease shortly after termination of employment, except in the case of death or disability. The exercise price of all stock options granted since the closing of our initial public offering is equal to the fair market value of shares of our common stock on the date of grant, which generally is determined by reference to the closing market price of our common stock on the date of grant.

Employment Agreements

We are a party to employment agreements with each of Dr. Peters and Ms. Franchi. Each of these agreements renews automatically on December 31 of each year for successive one year terms, unless either we or the named executive officer gives notice of non-renewal. We were previously a party to an employment agreement with Dr. Santillana prior to his resignation effective April 12, 2019. The following is a description of the employment agreements that we have with Dr. Peters and Ms. Franchi and that we had with Dr. Santillana prior to his resignation. See “Potential Payments Upon Termination or Change in Control” for a discussion of the Separation and Release of Claims Agreement we entered into with Dr. Santillana in connection with his resignation.

The employment agreements, and the non-disclosure, developments, non-competition and non-solicitation agreements that are incorporated therein, prohibit our named executive officers, during the term of employment and for a period of one year thereafter, from competing with us and soliciting or hiring our employees.

Pursuant to the terms of the employment agreements, our named executive officers currently receive (or in the case of Dr. Santillana, received) the following base salaries, which have been adjusted by our organization and compensation committee and board of directors since our named executive officers originally entered into the employment agreements, and are eligible for the following bonus percentages.

Amount reflects adjustment made by our organization and compensation committee and board of directors effective as of January 1, 2019.

Upon execution and effectiveness of a severance agreement and release of claims, each named executive officer is entitled to severance payments if we terminate the named executive officer’s employment without cause, as defined in the employment agreement, including our decision not to renew the named executive officer’s term of employment, or the named executive officer terminates employment with us for good reason, as defined in the employment agreement.

If a named executive officer’s employment terminates under these circumstances, in each case prior to a change in control, as defined in the employment agreement, we are obligated for a period of 12 months to pay such named executive officer his or her base salary and pay for coverage for such named executive officer under any company sponsored insurance and benefit programs available to our senior management employees. In addition, we would be obligated to pay to each of our named executive officers a pro-rata bonus for the portion of the year in which such named executive officer was employed by us based on his or her average annual bonus payments over each of the three years prior to the year of termination, or such lesser period during which such named executive officer served as one of our executive officers.

If a named executive officer’s employment terminates under these circumstances, in each case within 18 months following a change in control, we are obligated to pay such named executive officer a lump sum amount equal to 36 months of his or her base salary plus a bonus equal to three times the average of his or her annual bonus payments over each of the three years prior to the year of termination, or such lesser period during which such named executive officer served as one of our executive officers, accelerate the vesting of all outstanding stock options, restricted stock or other equity awards granted to the named executive officer and pay for coverage for such named executive officer under any company sponsored insurance and benefit programs available to our senior management employees for a period of 18 months.

In the event of termination of the named executive officer’s employment due to death or disability, the named executive officer (or his or her estate in the event of death) will be eligible to receive a pro-rata bonus for the portion of the year in which such named executive officer was employed by us based on his or her average annual bonus payments over each of the three years prior to the year of termination, or such lesser period during which such named executive officer served as one of our executive officers.

Potential Payments Upon Termination or Change in Control

The following tables set forth information regarding potential payments that each named executive officer who was serving as an executive officer as of December 31, 2018 would have received if the named executive officer’s employment had terminated as of December 31, 2018 under the circumstances set forth below. Dr. Santillana, who resigned effective April 12, 2019, entered into a Separation and Release of Claims Agreement with us as described below that provides for payments as if he had been terminated without cause.

We entered into a Separation and Release of Claims Agreement (the “Separation Agreement”) with Dr. Santillana on April 15, 2019. Pursuant to the Separation Agreement, in connection with Dr. Santillana’s resignation from his position as Chief Medical Officer, we agreed to:

 

   

commencing on the first regularly scheduled payroll date following June 11, 2019, continue paying Dr. Santillana’s annual base salary of $390,546 for a period of twelve (12) months following June 11, 2019 (the “Severance Period”);

 

   

continue paying the share of the premium for Dr. Santillana’s health and dental insurance through the end of the Severance Period that we currently pay on behalf of active and similarly situated employees who receive the same type of coverage and/or to otherwise continue to provide to Dr. Santillana during the Severance Period all employee benefit plans and arrangements available to our senior management employees;

 

   

on June 11, 2019, pay Dr. Santillana a pro-rated bonus of $32,266; and

 

   

waive any obligations that Dr. Santillana may have regarding the repayment of tuition reimbursements.

The Separation Agreement also includes a release of claims by Dr. Santillana against us.

401(k) Plan

We maintain a defined contribution employee retirement plan for our employees. Our 401(k) plan is intended to qualify as a tax-qualified plan under Section 401 of the Internal Revenue Code of 1986, as amended, so that contributions to our 401(k) plan, and income earned on such contributions, are not taxable to participants until withdrawn or distributed from the 401(k) plan. Our 401(k) plan provides that each participant may contribute up to 100% of his or her pre-tax compensation, up to a statutory limit, which was $18,500 for 2018. Participants who are at least 50 years old can also make “catch-up” contributions, which in 2018 was up to an

Table of Contents

additional $6,000 above the statutory limit. Under our 401(k) plan, each employee is fully vested in his or her deferred salary contributions. Employee contributions are held and invested by the plan’s trustee. Our 401(k) plan also permits us to make discretionary contributions and matching contributions, subject to established limits and a vesting schedule. For 2018, we generally matched 50% of employee contributions up to a maximum contribution by us of 3% of the employee’s deferrable income, subject to employer match limitations by the Internal Revenue Service. The match and any earnings thereon generally vest at 25% per year over the first four years of an employee’s employment, after which, any match that is contributed is 100% vested.

Item 12. Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters

Security Ownership of Certain Beneficial Owners and Management

The following table sets forth information with respect to the beneficial ownership of our common stock as of April 18, 2019 by:

 

   

each person, or group of affiliated persons, who is known by us to beneficially own more than 5% of our common stock;

 

   

each of our named executive officers;

 

   

each of our current directors; and

 

   

all of our executive officers and directors as a group.

Beneficial ownership is determined in accordance with the rules and regulations of the SEC and includes voting or investment power with respect to our common stock. Shares of our common stock subject to options that are currently exercisable or exercisable within 60 days after April 18, 2019 are considered outstanding and beneficially owned by the person holding the options for the purpose of calculating the percentage ownership of that person, but not for the purpose of calculating the percentage ownership of any other person. Except as otherwise noted, to our knowledge, the persons and entities in this table have sole voting and investing power with respect to all of the shares of our common stock beneficially owned by them, subject to community property laws, where applicable. The inclusion herein of any shares as beneficially owned does not constitute an admission of beneficial ownership.

The column entitled “Percentage of Shares Beneficially Owned” is based on a total of 13,342,909 shares of our common stock outstanding as of April 18, 2019. Except as otherwise set forth below, the address of the beneficial owner is c/o Merrimack Pharmaceuticals, Inc., One Kendall Square, Suite B7201, Cambridge, Massachusetts 02139. Beneficial ownership representing less than one percent of our outstanding common stock as of April 18, 2019 is denoted with an “*.”

Item 13. Certain Relationships and Related Transactions, and Director Independence

Related Person Transactions

Our board of directors has adopted written policies and procedures for the review of any transaction, arrangement or relationship in which Merrimack is 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.

Since January 1, 2017, we have not engaged in any related person transactions.

Board Determination of Independence

Rule 5605 of the Nasdaq Listing Rules requires a majority of a listed company’s board of directors to be comprised of independent directors. In addition, the Nasdaq Listing Rules require that, subject to specified exceptions, each member of a listed company’s audit, compensation and corporate governance and nominating committees be independent and that audit committee members also satisfy independence criteria set forth in Rule 10A-3 under the Exchange Act. Under Rule 5605(a)(2) of the Nasdaq Listing 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 that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. In order to be considered independent for purposes of Rule 10A-3, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the board of directors, or any other board committee: (1) accept, directly or indirectly, any consulting, advisory or other compensatory fee from the listed company or any of its subsidiaries; or (2) be an affiliated person of the listed company or any of its subsidiaries. In addition, in affirmatively determining the independence of any director who will serve on a company’s compensation committee, Rule 10C-1 under the Exchange Act requires that a company’s board of directors consider all factors specifically relevant to determining whether a director has a relationship to such company which is material to that director’s ability to be independent from management in connection with the duties of a compensation committee member, including, but not limited to: (i) the source of compensation of the director, including any consulting, advisory or other compensatory fee paid by such company to the director; and (ii) whether the director is affiliated with the company or any of its subsidiaries or affiliates.

Based upon information requested from and provided by each director concerning his or her background, employment and affiliations, including family relationships, our board of directors has determined that none of Mr. Crocker, Dr. Demetri, Mr. Dineen, Dr. Nielsen, Mr. Quigley and Mr. Ray, representing six of our seven current directors, 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 Rule 5605(a)(2) of the Nasdaq Listing Rules. Our board of directors had previously made a similar determination of independence with respect to Vivian S. Lee and Michael E. Porter, each of whom served as a director until our 2018 Annual Meeting of Stockholders. Our board of directors has also determined that Dr. Nielsen, Mr. Quigley and Mr. Ray, who comprise our audit committee, Mr. Crocker and Dr. Nielsen, who comprise our corporate governance and nominating committee, and Dr. Demetri, Mr. Dineen and Mr. Ray, who comprise our organization and compensation committee, each satisfy the independence standards for such committees established by the SEC and the Nasdaq Listing Rules, as applicable. In making such determination, our board of directors considered the relationships that each such non-employee director has with Merrimack, including any transactions of the type described above in “Related Person Transactions,” and all other facts and circumstances our board of directors deemed relevant in determining independence.
