Each of the committees has authority to engage legal counsel or other experts or consultants, as it deems appropriate to carry out its responsibilities. The Board has determined that each member of each committee meets the applicable Nasdaq listing rules and SEC rules and regulations regarding “independence” and each member is free of any relationship that would impair his or her individual exercise of independent judgment with regard to the Company. The Board has adopted a written charter for each of the Audit Committee, Compensation Committee and Nominating Committee, which charters are available to stockholders on the Company’s website at ir.mirumpharma.com .
