| • |     | for any transaction from which the director derives any improper personal benefit. |

Such limitation of liability does not apply to liabilities arising under federal securities laws and does not affect the availability of equitable remedies such as injunctive relief or rescission. Our Post-IPOCertificate of Incorporation will provide that if Delaware law is amended to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of our directors will be eliminated or limited to the fullest extent permitted by Delaware law. Our Post-IPOCertificate of Incorporation and our bylaws will provide that we are required to indemnify our executive officers and directors to the fullest 212

extent permitted by Delaware law. Our Post-IPO Bylaws will also provide that, on satisfaction of certain conditions, we will advance the expenses incurred
by a director or officer in advance of the final disposition of an action or proceeding, and permit us to secure insurance on behalf of any director, officer, employee, or other enterprise agent for any liability arising out of his or her action in
that capacity, whether or not Delaware law would otherwise permit indemnification.

We have entered into, and expect to continue to enter into, indemnification
agreements with each of our directors and executive officers and certain other key employees. With certain exceptions, these agreements will provide for indemnification for related expenses including attorneys’ fees, judgments, fines, and
settlement amounts incurred by any of these individuals in connection with any action, proceeding, or investigation. We believe that these provisions and indemnification agreements are necessary to attract and retain qualified persons as directors
and officers. We also currently carry and intend to continue to carry liability insurance for our directors and officers.

The limitation of liability and
indemnification provisions in our Post-IPO Certificate of Incorporation and our Post-IPO Bylaws may discourage stockholders from bringing a lawsuit against our directors
for breach of their fiduciary duty. They may also reduce the likelihood of derivative litigation against our directors and officers, even though an action, if successful, might benefit us and other stockholders. Furthermore, a stockholder’s
investment may be adversely affected to the extent that we pay the costs of settlement and damage awards against directors and officers as required by these indemnification provisions. At present, there is no pending litigation or proceeding
involving any of our directors, officers, or employees for which indemnification is sought, and we are not aware of any threatened litigation that may result in claims for indemnification.
