Geron has a commitment to good governance and business practices and adopted Corporate Governance Guidelines in May 2011. In furtherance of this commitment we regularly monitor developments in the area of corporate governance and review our processes and procedures in light of such developments. Geron complies with the rules and regulations promulgated by the Securities and Exchange Commission (SEC) and the National Association of Securities Dealers (NASD), and we implement those corporate governance practices we believe are in the best interest of the company and our stockholders.

Code of Conduct

In 2003, Geron adopted a Code of Conduct (the "Code of Conduct"), which is available below and also to any stockholder otherwise requesting a copy. All Geron employees, officers, and directors, including the Chief Executive Officer and Chief Financial Officer, are required to adhere to the Code of Conduct in discharging their work-related responsibilities. Employees are required to report any conduct that they believe in good faith to be an actual or apparent violation of the Code of Conduct. Amendments to the Code of Conduct, and any waivers from the Code of Conduct granted to directors or executive officers, will also be made available through this website as they are adopted.

In keeping with the Sarbanes-Oxley Act of 2002, the Audit Committee of the Board of Directors has established procedures for the receipt and handling of complaints received by the company regarding accounting, internal accounting controls or auditing matters. A copy of this policy is available above.

Committees of the Board of Directors

The Board maintains three standing committees - Compensation Committee, Audit Committee and Nominating & Corporate Governance Committee. Committee membership is determined by the Board, and all committee members are independent directors as determined by the Board. Each committee maintains a written charter detailing its authority and responsibilities. These charters are reviewed periodically as legislative and regulatory developments and business circumstances warrant and are available in their entirety below, as well as to any stockholder requesting a copy.

Stockholders wishing to communicate with the Board of Directors, or with a specific Board member, may do so by writing to the Board, or to the particular Board member, c/o Stephen N. Rosenfield, Secretary, Geron Corporation, 230 Constitution Drive, Menlo Park, CA 94025, or via email to Secretary@geron.com. All mail and email addressed in this manner will be delivered to the Chair or Chairs of the Committees with responsibilities touching most closely on the matters addressed in the communication.
