Scangos, Ph.D. resigned as a member of the Audit Committee of the Board of Directors (the &#8220;Board&#8221;) of Exelixis, Inc. (the &#8220;Company&#8221;), effective immediately. Dr. Scangos tendered this resignation in response to the concern expressed recently by Institutional Shareholder Services (&#8220;ISS&#8221;) over his service on the Audit Committee, given his prior service as the Company&#8217;s President and Chief Executive Officer. This concern resulted in ISS&#8217; negative recommendation with respect to Dr. Scangos&#8217; election to the Board at the Annual Meeting of Stockholders of the Company to be held on May 24, 2017 (the &#8220;Annual Meeting&#8221;). Despite the Board's opinion that Dr. Scangos' extensive qualifications make him an asset to the Audit Committee and that his prior service as the Company&#8217;s President and Chief Executive Officer, which ended in July 2010, did not interfere with the exercise of independent judgment in his carrying out the responsibilities of a director and a member of the Audit Committee, Dr. Scangos believed that since some of the Company&#8217;s stockholders may share the same concern as expressed by ISS, he should voluntarily resign from the Audit Committee. Dr. Scangos&#8217; resignation from the Audit Committee has no effect on his continued service as a member of the Board and he continues to be a nominee for election to the Board at the Annual Meeting. In addition, Charles Cohen, Ph.D., Stelios Papadopoulos, Ph.D. and Jack L. Wyszomierski, who the Board has determined is an &#8220;audit committee financial expert&#8221; as defined in applicable Securities and Exchange Commission rules, continue to serve on the Audit Committee. For further clarity, Dr. Scangos' resignation is not the result of a disagreement with any member of the Audit Committee or the Company's financial reporting.</font></div><div
