and transactions that might impair the directors’ independence. The Nominating and Corporate Governance Committee also takes into account the results of the self-evaluation or surveys of the Board of Directors, conducted annually. In the case of new director candidates, the Nominating and Corporate Governance Committee also determines whether the nominee is independent for Nasdaq purposes, which determination is based upon applicable Nasdaq listing standards, applicable SEC rules and regulations and the advice of counsel, if necessary. The Nominating and Corporate Governance Committee then uses its network of contacts to compile a list of potential candidates, but may also engage, if it deems appropriate, a professional search firm. The Nominating and Corporate Governance Committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of the Board of Directors. The Nominating and Corporate Governance Committee meets to discuss and consider the candidates’ qualifications and then selects a nominee for recommendation to the Board of Directors by majority vote.

The Nominating and Corporate Governance Committee will consider director candidates recommended by stockholders. The Nominating and Corporate Governance Committee does not intend to alter the manner in which it evaluates candidates, including the minimum criteria set forth above, based on whether or not the candidate was recommended by a stockholder. Stockholders who wish to recommend individuals for consideration by the Nominating and Corporate Governance Committee to become nominees for election to the Board of Directors may do so by delivering a written recommendation to the Nominating and Corporate Governance Committee in care of our Corporate Secretary at 20451 Seneca Meadows Parkway, Germantown, Maryland 20876-7005. Any such recommendation should be delivered at least 90 days, but no more than 120 days, prior to the anniversary date of the mailing of our proxy statement for the last Annual Meeting of Stockholders. Submissions must include the full name of the proposed nominee, a description of the proposed nominee’s business experience for at least the previous five years, complete biographical information, a description of the proposed nominee’s qualifications as a director and a representation that the nominating stockholder is a beneficial or record holder of our stock and has been a holder for at least one year. Any such submission must be accompanied by the written consent of the proposed nominee to be named as a nominee and to serve as a director if elected.

STOCKHOLDER COMMUNICATIONS WITH THE BOARD OF DIRECTORS

The Board of Directors has adopted a formal process by which stockholders and other interested parties may communicate with the Board of Directors or any of its directors. Stockholders and other interested parties who wish to communicate with the Board of Directors may do so by sending written communications addressed to the Board of Directors or the director in care of Senseonics Holdings, Inc., 20451 Seneca Meadows Parkway, Germantown, Maryland 20876-7005, Attn: Corporate Secretary. Each communication must set forth the name and address of the stockholder (or interested party) on whose behalf the communication is sent and the number and class of shares of our stock that are owned beneficially by the stockholder as of the date of the communication.

These communications will be reviewed by our Corporate Secretary, who will determine whether they should be presented to the Board of Directors. The purpose of this screening is to allow the Board of Directors to avoid having to consider communications that contain advertisements or solicitations or are unduly hostile, threatening or similarly inappropriate. All communications directed to the Audit Committee in accordance with our Amended and Restated Whistleblower Policy that relate to questionable accounting or auditing matters involving us will be promptly and directly forwarded to the Audit Committee.

Any interested person may communicate directly with the non-management directors. Persons interested in communicating directly with the non-management directors regarding their concerns or issues may do so by addressing correspondence to a particular director, or to the non-management directors generally, in care of Senseonics Holdings, Inc., 20451 Seneca Meadows Parkway, Germantown, Maryland 20876-7005. If no particular director is named, letters will be forwarded, depending upon the subject matter, to the chair of the Audit Committee, Compensation Committee, or Nominating and Corporate Governance Committee.
