      <div style="text-align: justify; text-indent: 27pt; color: #000000;">Section 145 of the Delaware General Corporation Law (the &#8220;DGCL&#8221;), permits a corporation to indemnify its directors and officers against expenses, including attorneys&#8217; fees,
        judgments, fines and amounts paid in settlements actually and reasonably incurred by them in connection with any action, suit or proceeding brought by third parties. The directors or officers must have acted in good faith and in a manner they
        reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reason to believe their conduct was unlawful. In a derivative action, an action only by or in the
        right of the corporation, indemnification may be made only for expenses, including attorney&#8217;s fees, actually and reasonably incurred by directors and officers in connection with the defense or settlement of an action or suit, and only with respect
        to a matter as to which they acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the corporation. No indemnification shall be made if such person shall have been adjudged to be liable to the
        corporation, unless and only to the extent that the court in which the action or suit was brought determines upon application that the defendant officers or directors are fairly and reasonably entitled to indemnity for such expenses despite such
        adjudication of liability. The amended and restated certificate of incorporation, as amended, of the registrant provides that the registrant may indemnify its directors, officers, employees or agents to the fullest extent permitted by applicable
        law and the amended and restated bylaws of the registrant provide that the registrant shall indemnify its directors and officers to the fullest extent permitted by applicable law.</div>

      <div style="text-align: justify; text-indent: 27pt; color: #000000;">Section 102(b)(7) of the DGCL permits a corporation to provide in its certificate of incorporation that a director or officer of the corporation shall not be personally liable to
        the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director or officer, except for liability of (1) a director or officer for any breach of the director&#8217;s or officer&#8217;s duty of loyalty to the corporation or
        its stockholders, (2) a director or officer for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) a director for payments of unlawful dividends or unlawful stock purchases or redemptions,
        (4) a director or officer for any transaction from which the director or officer derived an improper personal benefit, or (5) an officer in any action by or in the right of the corporation. The amended and restated certificate of incorporation, as
        amended, of the registrant provides for such limitation of liability with respect to directors and officers of the corporation.</div>

Item 6.
Indemnification of Directors and Officers
.
Section 145 of the Delaware General Corporation Law (the "DGCL"), permits a corporation to indemnify its directors and officers against expenses, including attorneys' fees,
        judgments, fines and amounts paid in settlements actually and reasonably incurred by them in connection with any action, suit or proceeding brought by third parties. The directors or officers must have acted in good faith and in a manner they
        reasonably believed to be in or not opposed to the best interests of the corporation and, with respect to any criminal action or proceeding, had no reason to believe their conduct was unlawful. In a derivative action, an action only by or in the
        right of the corporation, indemnification may be made only for expenses, including attorney's fees, actually and reasonably incurred by directors and officers in connection with the defense or settlement of an action or suit, and only with respect
        to a matter as to which they acted in good faith and in a manner they reasonably believed to be in or not opposed to the best interests of the corporation. No indemnification shall be made if such person shall have been adjudged to be liable to the
        corporation, unless and only to the extent that the court in which the action or suit was brought determines upon application that the defendant officers or directors are fairly and reasonably entitled to indemnity for such expenses despite such
        adjudication of liability. The amended and restated certificate of incorporation, as amended, of the registrant provides that the registrant may indemnify its directors, officers, employees or agents to the fullest extent permitted by applicable
        law and the amended and restated bylaws of the registrant provide that the registrant shall indemnify its directors and officers to the fullest extent permitted by applicable law.
Section 102(b)(7) of the DGCL permits a corporation to provide in its certificate of incorporation that a director or officer of the corporation shall not be personally liable to
        the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director or officer, except for liability of (1) a director or officer for any breach of the director's or officer's duty of loyalty to the corporation or
        its stockholders, (2) a director or officer for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (3) a director for payments of unlawful dividends or unlawful stock purchases or redemptions,
        (4) a director or officer for any transaction from which the director or officer derived an improper personal benefit, or (5) an officer in any action by or in the right of the corporation. The amended and restated certificate of incorporation, as
        amended, of the registrant provides for such limitation of liability with respect to directors and officers of the corporation.
We have entered into indemnification agreements with each of our directors and officers in which we have agreed to indemnify and hold harmless, and also advance expenses as
        incurred, to the fullest extent permitted under applicable law, against all expenses, losses and liabilities incurred by the indemnitee or on the indemnitee's behalf arising from the fact that such person is or was a director, officer, employee or
        agent of our company or our subsidiaries.
The indemnification rights set forth above shall not be exclusive of any other right which an indemnified person may have or hereafter acquire under any statute, our amended and
          restated certificate of incorporation, as amended, our amended and restated bylaws, any agreement, any vote of stockholders or disinterested directors or otherwise.
We maintain standard policies of insurance that provide coverage (1) to our directors and officers against loss rising from claims made by reason of breach of duty or other wrongful
        act and (2) to us with respect to indemnification payments that we may make to such directors and officers.
