  Item
  6. Indemnification of Directors and Officers
  As
  permitted by Section 102 of the Delaware General Corporation Law, we have adopted provisions in our Third Amended and Restated Certificate
  of Incorporation (the "Charter") and our amended and restated bylaws (the "Bylaws") that limit or eliminate the
  personal liability of our directors for a breach of their fiduciary duty of care as a director. The duty of care generally requires that,
  when acting on behalf of the corporation, directors exercise an informed business judgment based on all material information reasonably
  available to them. Consequently, a director will not be personally liable to us or our stockholders for monetary damages for breach of
  fiduciary duty as a director, except for liability for:
  ●
  any
  breach of the director's duty of loyalty to us or our stockholders;
  II-
  1
  ●
  any
  act or omission not in good faith or that involves intentional misconduct or a knowing violation of law;
  ●
  any
  act related to unlawful stock repurchases, redemptions or other distributions or payment of dividends; or
  ●
  any
  transaction from which the director derived an improper personal benefit.
  These
  limitations of liability do not affect the availability of equitable remedies such as injunctive relief or rescission. Our Charter also
  authorizes us to indemnify our officers, directors and other agents to the fullest extent permitted under Delaware law.
  As
  permitted by Section 145 of the Delaware General Corporation Law, our Bylaws provide that:
  ●
  we
  may indemnify our directors, officers and employees to the fullest extent permitted by the Delaware General Corporation Law, subject
  to limited exceptions;
  ●
  we
  may advance expenses to our directors, officers and employees in connection with a legal proceeding to the fullest extent permitted by
  the Delaware General Corporation Law, subject to limited exceptions; and
  ●
  the
  rights provided in our amended and restated bylaws are not exclusive.
  Our
  Charter and our Bylaws provide for the indemnification provisions described above and elsewhere herein. We have entered or will enter
  into, and intend to continue to enter into, separate indemnification agreements with our directors and officers that may be broader than
  the specific indemnification provisions contained in the Delaware General Corporation Law. These indemnification agreements generally
  require us, among other things, to indemnify our officers and directors against certain liabilities that may arise by reason of their
  status or service as directors or officers, other than liabilities arising from willful misconduct. These indemnification agreements
  also generally require us to advance any expenses incurred by the directors or officers as a result of any proceeding against them as
  to which they could be indemnified. These indemnification provisions and the indemnification agreements may be sufficiently broad to
  permit indemnification of our officers and directors for liabilities, including reimbursement of expenses incurred, arising under the
  Securities Act of 1933, as amended, or the Securities Act.

  Item
  9. Undertakings
  Undertaking
  Required by Item 512(a) of Regulation S-K
  : The undersigned registrant 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)
  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 SEC pursuant to Rule 424(b) if, in the aggregate, the changes in volume and
  price represent no more than 20% change in the maximum aggregate offering price set forth in the "Calculation of Registration Fee"
  table in the effective registration statement; and
  (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.
  (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.
  Undertaking
  Required by Item 512(b) of Regulation S-K
  : The undersigned registrant hereby undertakes that, for purposes of determining any liability
  under the Securities Act, each filing of the registrant's annual report pursuant to section 13(a) or section 15(d) of the Securities
  Exchange Act (and, where applicable, each filing of an employee benefit plan's annual report pursuant to section 15(d) of the Securities
  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 therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering
  thereof.
  Undertaking
  Required by Item 512(h) of Regulation S-K
  : Insofar as indemnification for liabilities arising under the Securities Act 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 SEC 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.
