1. Identify the Candidate

The NCG Committee identifies nominees by first evaluating the current members of the Board willing to continue in service. If any member of the Board does not wish to continue in service, if the Board decides not to re-nominate a member for re-election or if the Board decides to increase the size of the Board, the NCG Committee identifies the desired skills and experience of a new nominee in light of the philosophy explained below.

Current directors are polled for suggestions as to individuals meeting the philosophy of the NCG Committee and the NCG Committee has the authority to select, engage, compensate, and terminate third-party search firms, legal counsel, and other advisors as it deems necessary and advisable to assist the NCG Committee in carrying out its responsibilities and functions as set forth herein. Dr. Chan was initially recommended by Dr. Kibarian and then reviewed and recommended to the Board by the NCG Committee.

2. Confirm Candidate Qualifications

Once the NCG Committee has identified a prospective nominee or if it has received a recommendation from a stockholder, the NCG Committee makes an initial determination as to whether to conduct a full evaluation of the candidate.

This initial determination is based on the information provided to the NCG Committee concerning the prospective candidate, as well as the NCG Committee’s own knowledge of the prospective candidate, which may be supplemented by inquiries to the person making the recommendation or others. The preliminary determination is based primarily on the need for additional Board members to fill vacancies or expand the size of the Board and the likelihood that the prospective nominee can satisfy the evaluation factors described below.

3. Candidate Evaluation

The NCG Committee then evaluates the prospective nominee, considering the following:

other expertise on our Board of Directors or its committees; and

In connection with this evaluation, the NCG Committee determines whether to interview the prospective nominee and, if warranted, one or more members of the NCG Committee and others, as appropriate, conduct interviews in person or by telephone.

4. Committee Recommendation

After completing this process, the NCG Committee makes a recommendation to the full Board as to the persons who should be nominated by the Board, and the Board determines the nominees.

5. Stockholder Vote

Director nominees are then elected by the Company’s stockholders at the Annual Meeting. Since 2018, five new independent directors have been elected to our Board, representing over 62% of our Board. We believe each Director brings a diverse set of skills and perspectives that add significant value to our governance and oversight.
