**All board members have global expansion and distribution experience, as well as high level strategic corporate development knowledge. While we do not have a formal policy on diversity for members of the board of directors, the nominating and corporate governance committee values and, as reasonable, acts on the need for a variety of skills, experiences, viewpoints and characteristics when considering new candidates. Family Relationships Chad Robins, our Chief Executive Officer and Chairman of our board of directors, is the brother of Dr. Harlan Robins, our Chief Scientific Officer. There are no other family relationships among any of our directors or executive officers. 10

Board Leadership Structure

Our board of directors has concluded that our current board leadership structure is appropriate for Adaptive’s needs at this time. Our board of directors continues to believe that the combined role of chairperson and chief executive officer promotes united leadership and direction and provides management a clear focus to execute our strategy and business plans. As Chief Executive Officer, Mr. Robins is best suited to ensure that critical business issues are brought before our board of directors, which enhances our board of directors’ ability to develop and implement business strategies.

In his role as lead independent director, Mr. Neupert presides over the independent director sessions of our board of directors in which Mr. Robins, as our Chief Executive Officer, does not participate and serves as a liaison to management on behalf of the non-employee members of our board of directors. Mr. Neupert has been on our board of directors since December 2013, is an independent director who serves on our compensation and human capital committee, audit committee and our nominating and corporate governance committee, has been an executive officer of public companies, and has meaningful experience as an independent director for other public companies. Accordingly, we believe Mr. Neupert provides a strong voice for our independent directors.

All directors are encouraged to suggest the inclusion of agenda items and meeting materials, and any director is free to raise at any board meeting items that are not on the agenda for that meeting.

Our non-employee directors regularly meet in executive sessions without the presence of any members of management. The lead independent director presides at these meetings and provides the guidance and feedback of our non-employee directors to our Chairman and management team.

Our board of directors,
