  the Company of expenses incurred or paid by a director, officer or controlling person of the Company 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 Company 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 Securities Act and will be governed

  Item 6. Indemnification of Directors and Officers.
  Section 102 of the DGCL permits a corporation
  to eliminate the personal liability of directors of a corporation to the corporation or its stockholders for monetary damages for a breach
  of fiduciary duty as a director, except where the director breached his duty of loyalty, failed to act in good faith, engaged in intentional
  misconduct or knowingly violated a law, authorized the payment of a dividend or approved a stock repurchase in violation of Delaware corporate
  law or obtained an improper personal benefit. Our certificate of incorporation provides that no director of the Registrant shall be personally
  liable to it or its stockholders for monetary damages for any breach of fiduciary duty as a director, notwithstanding any provision of
  law imposing such liability, except to the extent that the DGCL prohibits the elimination or limitation of liability of directors for
  breaches of fiduciary duty.
  Section 145 of the DGCL provides that a corporation
  has the power to indemnify a director, officer, employee, or agent of the corporation, or a person serving at the request of the corporation
  for another corporation, partnership, joint venture, trust or other enterprise in related capacities against expenses (including attorneys'
  fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with an action, suit
  or proceeding to which he was or is a party or is threatened to be made a party to any threatened, ending or completed action, suit or
  proceeding by reason of such position, if such person acted in good faith and in a manner he reasonably believed to be in or not opposed
  to the best interests of the corporation, and, in any criminal action or proceeding, had no reasonable cause to believe his conduct was
  unlawful, except that, in the case of actions brought by or in the right of the corporation, no indemnification shall be made with respect
  to any claim, issue or matter as to which such person shall have been adjudged to be liable to the corporation unless and only to the
  extent that the Court of Chancery or other adjudicating court determines that, despite the adjudication of liability but in view of all
  of the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery
  or such other court shall deem proper.
  Our certificate of incorporation provides that
  we will indemnify each person who was or is a party or threatened to be made a party to any threatened, pending or completed action, suit
  or proceeding (other than an action by or in the right of us) by reason of the fact that he or she is or was, or has agreed to become,
  a director or officer, or is or was serving, or has agreed to serve, at our request as a director, officer, partner, employee or trustee
  of, or in a similar capacity with, another corporation, partnership, joint venture, trust or other enterprise (all such persons being
  referred to as an "Indemnitee"), or by reason of any action alleged to have been taken or omitted in such capacity, against
  all expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred in connection
  with such action, suit or proceeding and any appeal therefrom, if such Indemnitee acted in good faith and in a manner he or she reasonably
  believed to be in, or not opposed to, our best interests, and, with respect to any criminal action or proceeding, he or she had no reasonable
  cause to believe his or her conduct was unlawful. Our certificate of incorporation provides that we will indemnify any Indemnitee who
  was or is a party to an action or suit by or in the right of us to procure a judgment in our favor by reason of the fact that the Indemnitee
  is or was, or has agreed to become, a director or officer, or is or was serving, or has agreed to serve, at our request as a director,
  officer, partner, employee or trustee of, or in a similar capacity with, another corporation, partnership, joint venture, trust or other
  enterprise, or by reason of any action alleged to have been taken or omitted in such capacity, against all expenses (including attorneys'
  fees) and, to the extent permitted by law, amounts paid in settlement actually and reasonably incurred in connection with such action,
  suit or proceeding, and any appeal therefrom, if the Indemnitee acted in good faith and in a manner he or she reasonably believed to be
  in, or not opposed to, our best interests, except that no indemnification shall be made with respect to any claim, issue or matter as
  to which such person shall have been adjudged to be liable to us, unless a court determines that, despite such adjudication but in view
  of all of the circumstances, he or she is entitled to indemnification of such expenses. Notwithstanding the foregoing, to the extent that
  any Indemnitee has been successful, on the merits or otherwise, he or she will be indemnified by us against all expenses (including attorneys'
  fees) actually and reasonably incurred in connection therewith. Expenses must be advanced to an Indemnitee under certain circumstances.
  We have entered into indemnification agreements
  with each of our directors and officers. These indemnification agreements may require us, among other things, to indemnify our directors
  and officers for some expenses, including attorneys' fees, judgments, fines and settlement amounts incurred by a director or officer
  in any action or proceeding arising out of his or her service as one of our directors or officers, or any of our subsidiaries or any other
  company or enterprise to which the person provides services at our request.
  We maintain a general liability insurance policy
  that covers certain liabilities of directors and officers of our corporation arising out of claims based on acts or omissions in their
  capacities as directors or officers.
  In any underwriting agreement we enter into in
  connection with the sale of common stock being registered hereby, the underwriters will agree to indemnify, under certain conditions,
  us, our directors, our officers and persons who control us within the meaning of the Securities Act against certain liabilities.

  Item 9. Undertakings.
  (a) The undersigned Company hereby undertakes:
  (1) To file, during any period in which offers or sales are being made,
  a post-effective amendment to this Registration Statement:
  (i) To include any prospectus required by Section 10(a)(3) of the Securities
  Act;
  II-
  3
  (ii) To reflect in the prospectus any facts or events arising after
  the effective date of the Registration Statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate,
  represent a fundamental change in the information set forth in the Registration Statement. Notwithstanding the foregoing, any increase
  or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered)
  and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with
  the Commission pursuant to Rule 424(b) if, in the aggregate, the changes in volume and price represent no more than a 20 percent change
  in the maximum aggregate offering price set forth in the "Calculation of Registration Fee" table in the effective registration
  statement;
  (iii) To include any material information with respect to the plan
  of distribution not previously disclosed in the Registration Statement or any material change to such information in the Registration
  Statement;
  provided, however
  , that paragraphs (a)(1)(i) and (a)(1)(ii)
  of this section do not apply if the registration statement is on Form S-8, and the information required to be included in a post-effective
  amendment by those paragraphs is contained in periodic reports filed by or furnished to the Commission by the Company pursuant to Section
  13 or Section 15(d) of the Exchange Act that are incorporated by reference in the Registration Statement.
  (2) That, for the purpose of determining any liability under the Securities
  Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein,
  and the offering of such securities at that time shall be deemed to be the initial
  bona fide
  offering thereof.
  (3) To remove from registration by means of a post-effective amendment
  any of the securities being registered which remain unsold at the termination of the offering.
  (b) The undersigned Company hereby undertakes that, for purposes of
  determining any liability under the Securities Act, each filing of the Company's annual report pursuant to Section 13(a) or Section
  15(d) of the Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to Section 15(d)
  of the Exchange Act) that is incorporated by reference in the Registration Statement shall be deemed to be a new registration statement
  relating to the securities offered herein, and the offering of such securities at that time shall be deemed to be the initial
  bona
  fide
  offering thereof.
  (c) Insofar as indemnification for liabilities arising under the Securities
  Act may be permitted to directors, officers and controlling persons of the Company pursuant to the foregoing provisions, or otherwise,
  the Company has been advised that in the opinion of the Commission such indemnification is against public policy as expressed in the Securities
  Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by
  the Company of expenses incurred or paid by a director, officer or controlling person of the Company 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 Company 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 Securities Act and will be governed
  by the final adjudication of such issue.
