A director of this Corporation shall not be personally liable to this Corporation or any of its stockholders for monetary damages for breach of fiduciary duty as a director; provided, however, that to the extent required by the provisions of Section 102(b)(7) of the DGCL or any successor statute, or any other laws of the State of Delaware, this provision shall not eliminate or limit the liability of a director (i) for any breach of the director’s duty of loyalty to this Corporation or its stockholders, (ii) for acts or omissions not in good faith or that involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the DGCL, or (iv) for any transaction from which the director derived any improper personal benefit. If the DGCL is amended after approval by the stockholders of this Article Seventh to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director of this Corporation shall be eliminated or limited to the fullest extent permitted by the DGCL as so amended.

Any repeal or modification of the foregoing provisions of this Article Seventh by the stockholders of this Corporation shall not adversely affect any right or protection of a director of this Corporation existing at the time of, or increase the liability of any director of this Corporation with respect to any acts or omissions of such director occurring prior to, such repeal or modification.

Subject to such limitations as may be from time to time imposed by other provisions of this Certificate of Incorporation, by the bylaws of the Corporation, by the DGCL or other applicable law, or by any contract or agreement to which the Corporation is or may become a party, the Corporation reserves the right to amend or repeal any provision contained in this Certificate of Incorporation, in the manner now or hereafter prescribed by statute, and all rights conferred upon stockholders herein are granted subject to this express reservation.

TENTH

Unless the Corporation consents in writing to the selection of an alternative forum (an “Alternative Forum Consent”), the Court of Chancery of the State of Delaware shall be the sole and exclusive forum for (i) any derivative action or proceeding brought on behalf of the Corporation, (ii) any action asserting a claim of breach of a duty (including any fiduciary duty) owed by any current or former director, officer, stockholder, employee or agent of the Corporation to the Corporation or the Corporation’s stockholders, (iii) any action asserting a claim against the Corporation or any current or former director, officer, stockholder, employee or agent of the Corporation arising out of or relating to any provision of the General Corporation Law or this Certificate of Incorporation or the bylaws of the Corporation, or (iv) any action asserting a claim against the Corporation or any current or former director, officer, stockholder, employee or agent of the Corporation governed by the internal affairs doctrine of the State of Delaware; provided, however, that, in the event that the Court of Chancery of the State of Delaware lacks subject matter jurisdiction over any such action or proceeding, the sole and exclusive forum for such action or proceeding shall be another state or federal court located within the State of Delaware, in each such case, unless the Court of Chancery (or such other state or federal court located within the State of Delaware, as applicable) has dismissed a prior action by the same plaintiff asserting the same claims because such court lacked personal jurisdiction over an indispensable party named as a defendant therein. Unless the Corporation gives an Alternative Forum Consent, the federal district courts of the United States of America shall, to the fullest extent permitted by law, be the sole and exclusive forum for the resolution of any complaint asserting a cause of action arising under the Securities Act of 1933, as amended, or the rules and regulations thereunder. Failure to enforce the foregoing provisions would cause the Corporation irreparable harm and the Corporation shall be entitled to equitable relief, including injunctive relief and specific performance, to enforce the foregoing provisions. Any person or entity purchasing, otherwise acquiring or holding any interest in shares of capital stock of the Corporation shall be deemed to have notice of and consented to the provisions of this Article Tenth. The existence of any prior Alternative Forum Consent shall not act as a waiver of the Corporation’s ongoing consent right as set forth above in this Article Tenth with respect to any current or future actions or claims.
