### TABLE OF CONTENTS
Information Regarding the Board of Directors and Corporate Governance

#### Board Leadership Structure
The Board has an independent, non-executive Chair, Mr. Grey, who has authority, among other things, to call and preside over Board meetings, including meetings of the independent directors, to set meeting agendas and to determine materials to be distributed to the Board. Accordingly, the Board Chair has substantial ability to shape the work of the Board. Our Board believes that it is in the best interests of the Company and its stockholders for Mr. Grey continue to serve as Chair of the Board, in part given his significant knowledge and experience in our industry and therapeutic areas of interest, as well as a deep understanding of our company, our business and our strategic objectives, all of which our Board believes will continue to benefit the Company during the year ahead. Our Board believes that separation of the positions of Board Chair and Chief Executive Officer reinforces the independence of the Board in its oversight of the business and affairs of the Company. In addition, we believe that having an independent Board Chair creates an environment that is more conducive to objective evaluation and oversight of management’s performance, increasing management accountability and improving the ability of the Board to monitor whether management’s actions are in the best interests of the Company and its stockholders. As a result, we believe that the leadership structure of our Board is appropriate and enhances its ability to effectively carry out its roles and responsibilities on behalf of our stockholders. We also have a separate Chair for each committee of the Board. The Chair of each committee reports periodically to the Board on the activities of their committee in fulfilling their responsibilities as detailed in their respective charters.

#### Role of the Board in Risk Oversight
One of the Board’s key functions is informed oversight of the Company’s risk management process. The Board does not have a standing risk management committee, but rather administers this oversight function directly through the Board as a whole, as well as through various Board standing committees that address risks inherent in their respective areas of oversight.
