ARTICLE VIII

1. The Board of Directors shall consist of not fewer than seven (7) or more than fifteen (15) persons. The exact number within such minimum and maximum limits shall be fixed and determined by resolution of
the Board of Directors from time to time. The number of directors elected by the shareholders at the last preceding annual meeting may be increased by not more than two (2) directors by the Board between annual meetings of the shareholders, and
no decrease in the number of directors shall have the effect of shortening the term of any incumbent.

three (3) years, so that term of office of one class of directors shall expire each year.

4. When the number of directors is changed,
any newly created directorships or any decrease in directorships shall be so apportioned among the classes as to make all classes as nearly equal in number as possible. Any director elected to fill a vacancy shall hold office for the unexpired
portion of the term of the director whose place he or she has been elected to fill, even though that term may extend beyond the next annual meeting.

2. Liability of Directors:No director, officer-director, former director or former officer-director of the corporation shall be personally liable to the corporation or its shareholders for monetary damages for conduct as a director
or officer-director occurring after the effective date of this Article IX unless the conduct is finally adjudged to have been egregious conduct, as defined herein.

3. Liability of Subsidiary Directors: No director, officer-director, former director, or former officer-director of a subsidiary corporation shall be personally liable in any action brought directly by this
corporation as a shareholder of the subsidiary corporation or derivatively on behalf of the subsidiary corporation (or by any shareholder of this corporation double-derivatively on behalf of this corporation and the subsidiary corporation) for
monetary damages for conduct as a director or officer-director of such subsidiary corporation occurring after the effective date of this Article IX unless the conduct is finally adjudged to have been egregious conduct, as defined herein.

4. Indemnification of Directors: The corporation shall indemnify any person who is, or is threatened to be made, a party to any action, suit,
or proceeding, whether civil, criminal, administrative, or investigative, and whether by or in the right of the corporation or its shareholders or by any other party, by reason of the fact that the person is or was a director or officer-director of
the corporation or of a subsidiary corporation against judgments, penalties or penalty taxes, fines, settlements (even if paid or payable to the corporation or its shareholders or to a subsidiary corporation) and reasonable expenses, including
attorneys fees, actually incurred in connection with such proceeding unless the liability and expenses were on account of conduct finally adjudged to be egregious conduct, as defined herein. The reasonable expenses, including attorneys
fees, of such person incurred in connection with such proceeding shall be paid or reimbursed by the corporation, upon request of such person, in advance of the final disposition of such proceeding upon receipt by the corporation of a written,
unsecured promise by the person to repay such amount if it shall be finally adjudged that the person is not eligible for indemnification. All expenses incurred by such person in connection with such proceeding shall be considered reasonable unless
finally adjudged to be unreasonable.

any other person or persons shall be necessary or appropriate to the determination of the corporations indemnification obligation in any specific case, to the determination of the reasonableness of any expenses incurred by a person entitled to

entitled hereby to indemnification in connection with the claim.

7. Enforcement of Rights: The corporation shall indemnify any
person granted indemnification rights under this Article IX against any reasonable expenses incurred by the person to enforce such rights.

8. Set-off of Claims: Any person granted indemnification rights herein may directly assert such rights in set-off of any claim raised against the person by or in the right of the corporation and shall be entitled to have the same
tribunal which adjudicates the corporations claim adjudicate the persons entitlement to indemnification by the corporation.

9.
Continuation of Rights: The indemnification rights provided in this Article IX shall continue as to a person who has ceased to be a director or officer-director and shall inure to the benefit of the heirs, executors, and administrators of
such person.

10. Effect of Amendment or Repeal: Any amendment or repeal of this Article IX shall not adversely affect any right or
protection of a director, officer-director, former director or former officer-director existing at the time of such amendment or repeal with respect to acts or omissions occurring prior to such amendment or repeal.

11. Severability of Provisions: Each of the substantive provisions of this Article IX is separate and independent of the others, so that if any
provision hereof shall be held to be invalid or unenforceable for any reason, such invalidity or unenforceability shall not affect the validity or enforceability of the other provisions.

These Second Amended and Restated Articles are executed by the corporation by its duly authorized officer, and supersede the original Articles of
