Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On September 13, 2017, the Board of Directors (the “Board”) of Merrimack Pharmaceuticals, Inc. (the “Company”), upon the recommendation of the Organization and Compensation Committee of the Board, approved the annual performance-based cash bonus program for 2017 (the “2017 Bonus Program”) for Richard Peters, the Company’s President and Chief Executive Officer, and Jean M. Franchi, the Company’s Chief Financial Officer and Treasurer.

The 2017 Bonus Program is comprised of the following two elements: (1) the achievement of specified annual individual performance objectives; and (2) the embodiment of the Company’s values and expected behaviors.

Dr. Peters’ individual performance objectives for 2017 generally relate to building the Company’s culture, staffing key positions, advancing the Company’s pipeline, enhancing the external reputation of the Company and pursuing various corporate development opportunities.

Ms. Franchi’s individual performance objectives for 2017 generally relate to managing the Company’s financials and related projections, enhancing the external reputation of the Company and meeting the Company’s financial disclosure requirements.

The Company’s values consist of being passionate, team focused, authentic and a continuous learner. The Company’s expected behaviors include thinking strategically, innovating and building the organization.

For each of the two foregoing elements, the Board will assess retroactively whether Dr. Peters and Ms. Franchi have not met expectations, have met expectations or have far exceeded expectations. The Board will then use the following table to determine the maximum percentage of Dr. Peters’ and Ms. Franchi’s target bonus for which he or she will be eligible. The Board may use its discretion to determine the amount of the bonus up to the maximum percentage provided.
