corporation or otherwise), civil or criminal, or in connection with an appeal relating thereto, in which he may be involved, as a party or otherwise, by reason of his being or having been a director,
officer or employee of the Corporation or such other corporation, or by reason of any action taken or not taken in his capacity as such director, officer or employee, whether or not he continues to be
such at the time such liability or expense shall have been incurred, provided such person acted, in good faith, in a manner he reasonably believed to be in or not opposed to the best interests of the
Corporation, or such other corporation, as the case may be, and in addition, in any criminal action or proceeding, had no reasonable cause to believe that his conduct was unlawful. As used in this
Section 12, the terms "liability" and "expense" shall include, but shall not be limited to, counsel fees and disbursements and amounts of judgments, fines or penalties against, and amounts paid
in settlement by, a director, officer, or employee. The termination of any claim, action, suit or proceeding, civil or criminal, by judgment, settlement (whether with or without court approval),
conviction or upon a plea of guilty or nolo contendere, or its equivalent, shall not create a presumption that a director, officer or employee did not meet the standards of conduct set forth in this
Section 12.

Expenses
incurred with respect to any claim, action, suit or proceeding of the character described in this Section 12 may be advanced by the Corporation prior to the final
disposition thereof upon

receipt
of an undertaking by or on behalf of the recipient to repay such amount unless it shall ultimately be determined that he is entitled to indemnification hereunder.

The
rights of indemnification provided in this Section 12 shall be in addition to any other rights to which any such director, officer or employee may otherwise be entitled by
contract or as a matter of law; and in the event of any such person's death, such rights shall extend to his heirs and legal representatives. The provisions of this Section 12 are separable,
and if any provision be held invalid, all other provisions are fully in effect and such invalid provision shall only be curtailed to the extent necessary to make such provision enforceable, it being
the intent of this Section that the Corporation indemnify each of the directors, officers and employees of the Corporation to the maximum extent permitted by law.

Notwithstanding
the foregoing provision of this Section, the Corporation shall not indemnify persons seeking indemnity in connection with any threatened, pending or completed action,
suit or proceeding voluntarily brought or threatened by such person unless such action, suit or proceeding was authorized by a majority of the entire Board of Directors.

Directors shall provide otherwise, a majority of the members of any such committee may fix the time and place of its meetings. The Board of Directors shall have the power at any time to fill vacancies
in, change the membership of, or dissolve any such committee. Nothing herein shall be deemed to prevent to the Board of Directors from appointing committees consisting in whole or in part of persons
who are not directors of the Corporation, provided, however, that no such committee shall have or exercise any authority of the Board of Directors.

of a certificate for shares duly endorsed or accompanied by proper evidence of succession, assignment or authority to transfer, the Corporation may issue a new certificate, or, upon request, evidence

amounts to bad faith.

stockholders entitled to notice of or to vote at any meeting of stockholders or any adjournment thereof, or to express consent to corporate action in writing without a meeting, or entitled to receive
payment of any dividend or other distribution or allotment of any rights, or entitled to exercise any rights in respect to any change, conversion or exchange of stock or for the purpose of any other
lawful action, the Board of Directors may fix, in advance, a record date, which shall be not more than sixty (60) nor less than ten (10) days prior to the date of such meeting, nor more
