Item 14. Indemnification of Directors and Officers

Section 145 of the Delaware General Corporation Law (DGCL) authorizes a corporation's board of directors to grant indemnity to directors and officers in
terms sufficiently broad to permit indemnification under certain circumstances for liabilities (including reimbursement for expenses incurred) arising under the Securities Act.

As
permitted by the DGCL, the Registrant's bylaws provide that the Registrant shall indemnify its directors, officers, employees and agents to the fullest extent permitted by the
DGCL. As permitted by the DGCL, the Registrant's certificate of incorporation includes a provision that eliminates the personal liability of its directors for monetary damages for breach of the
director's fiduciary duty, except for liability (1) for any breach of the director's duty of loyalty to the Registrant or its stockholders; (2) for acts or omissions not in good faith or
that involve intentional misconduct or a knowing violation of law; (3) under Section 174 of the DGCL regarding payments of dividends, stock purchases or redemptions which are unlawful;
or (4) for any transaction from which the director derived an improper personal benefit.

The
Registrant also intends to maintain director and officer liability insurance.

The
underwriting agreement filed as Exhibit 1.1 to this Registration Statement contains provisions indemnifying officers and directors of the Registrant against liabilities
arising under the Securities Act, or otherwise.

Item 17. Undertakings

The undersigned registrant hereby undertakes to provide to the underwriters at the closing specified in the underwriting agreement certificates in such
denominations and registered in such names as required by the underwriters to permit prompt delivery to each purchaser.

Insofar
as indemnification for liabilities arising under the Securities Act of 1933 may be permitted to directors, officers and controlling persons of the registrant pursuant to the
foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the Securities and Exchange Commission such indemnification is against public policy as expressed in the Act
and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer
or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being
registered, the registrant will, unless in the opinion of its counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such
indemnification by it is against public policy as expressed in the Act and will be governed by the final adjudication of such issue.

The
undersigned registrant hereby undertakes that:
