10. No director of this Company shall be personally liable to the Company or its shareholders for monetary damages for breach of fiduciary duty as a director. Nothing in this paragraph shall serve to eliminate or limit the liability of a director (a) for any breach of the director’s duty of loyalty to this Company or its shareholders, (b) for acts or omissions not in good faith or which involves intentional misconduct or a knowing violation of law, (c) under Section 174 of the Delaware General Corporation Law, or (d) for any transaction from which the director derived an improper personal benefit. If the Delaware General Corporation Law is amended after approval by the shareholders of this article to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director of the Company shall be eliminated or limited to the fullest extent permitted by the Delaware General Corporation Law, as so amended.

Any repeal or modification of the foregoing paragraph by the shareholders of the Company shall not adversely affect any right or protection of a director of the Company existing at the time of such repeal or modification.

11. (a) Each person who was or is made a party or is threatened to be made a party to or is otherwise involved in any action, suit or proceeding (except as provided in Section 11 (f)) whether civil, criminal or administrative, (a “Proceeding”), or is contacted by any governmental or regulatory body in connection with any investigation or inquiry (an “Investigation”), by reason of the fact that he or she is or was a director or executive officer (as such term is utilized pursuant to interpretations under Section 16 of the Securities Exchange Act of 1934) of the Company or is or was serving at the request of the Company as a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to employee benefit plans (an “Indemnitee”), whether the basis of such Proceeding or Investigation is alleged action in an official capacity or in any other capacity as set forth above shall be indemnified and held harmless by the Company to the fullest extent authorized by the Delaware General Corporation Law, as the same exists or may hereafter be amended (but, in the case of any such amendment, only to the extent that such amendment permits the Company to provide broader indemnification rights than such law permitted the Company to provide prior to such amendment), against all expense, liability and loss (including attorneys’ fees, judgments, fines, ERISA excise taxes or penalties and amounts paid in settlement) reasonably incurred or suffered by such Indemnitee in connection therewith and such indemnification shall continue as to an Indemnitee who has ceased to be a director, officer, employee or agent and shall inure to the benefit of the Indemnitee’s heirs, executors and administrators. The right to indemnification conferred in this Section shall be a contract right and shall include the right to be paid by the Company the expenses incurred in defending any such Proceeding in advance of its final disposition (an “Advancement of Expenses”); provided, however, that an Advancement of Expenses shall be made only upon delivery to the Company of an undertaking, by or on behalf of such Indemnitee, to repay all amounts so advanced if it shall ultimately be determined by final judicial decision from which there is no further right to appeal that such Indemnitee is not entitled to be indemnified for such expenses under this Section or otherwise (an “Undertaking”).

(b) If a claim under paragraph (a) of this Section is not paid in full by the Company within 60 days after a written claim has been received by the Company, except in the case of a claim for an Advancement of Expenses, in which case the applicable period shall be 20 days, the Indemnitee may at any time thereafter bring suit against the Company to recover the unpaid amount of the claim. If successful in whole or in part in any such suit or in a suit brought by the Company to recover an Advancement of Expenses pursuant to the terms of an Undertaking, the Indemnitee shall be entitled to be paid also the expense of prosecuting or defending such suit. In

(i) any suit brought by the Indemnitee to enforce a right to indemnification hereunder (but not in a suit brought by the Indemnitee to enforce a right to an Advancement of Expenses) it shall be a defense that, and

(ii) any suit by the Company to recover an Advancement of Expenses pursuant to the terms of an Undertaking the Company shall be entitled to recover such expenses upon a final adjudication that, the Indemnitee has not met the applicable standard of conduct set forth in the Delaware General Corporation Law. Neither the failure of the Company (including its board of directors, independent legal counsel, or its shareholders) to have made a determination prior to the commencement of such suit that indemnification of the Indemnitee is proper in the circumstances because the Indemnitee has met the applicable standard of conduct set forth in the Delaware General Corporation Law, nor an actual determination by the Company (including its board of directors, independent legal counsel, or its shareholders) that the Indemnitee has not met such applicable standard of conduct or, in the case of such a suit brought by the Indemnitee, be a defense to such suit. In any suit brought by the Indemnitee to enforce a right hereunder, or by the Company to recover an Advancement of Expenses pursuant to the terms of an undertaking, the burden of proving that the Indemnitee is not entitled to be indemnified or to such Advancement of Expenses under this Section or otherwise shall be on the Company.

(c) The rights to indemnification and to the Advancement of Expenses conferred in this Section shall not be exclusive of any other right which any person may have or hereafter acquire under any statute, this certificate of incorporation, bylaw, agreement, vote of shareholders or disinterested directors or otherwise.

(d) The Company may maintain insurance, at its expense, to protect itself and any director, officer, employee or agent of the Company or another corporation, partnership, joint venture, trust or other enterprise against any expense, liability or loss, whether or not the Company would have the power to indemnify such person against such expense, liability or loss under the Delaware General Corporation Law.

(e) The Company may, to the extent authorized from time to time by the board of directors, grant rights to indemnification and to the Advancement of Expenses, to any employee or agent of the Company to the fullest extent of the provisions of this Section with respect to the indemnification and Advancement of Expenses of directors, and executive officers of the Company.

(f) Notwithstanding the indemnification provided for by this Section 11, the Company’s bylaws, or any written agreement, such indemnity shall not include any Advancement of Expenses incurred by such Indemnitees relating to or arising from any Proceeding in which the Company asserts a direct claim against an Indemnitee, or an Indemnitee asserts a direct claim against the Company, whether such claim is termed a complaint, counterclaim, crossclaim, third-party complaint or otherwise. Following the termination of any Proceeding referred to in this Section 11(f), the Company may provide indemnification in accordance with this Section 11, the Company’s bylaws, any written agreement or the Delaware General Corporation Law.

12. This Certificate of Incorporation and the internal affairs of the Company shall be governed by and interpreted under the laws of the State of Delaware, excluding its conflict of laws principles. Unless the Company consents in writing to the selection of an alternative forum, 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 Company, (ii) any action asserting a claim of breach of a fiduciary duty owed by any director or officer (or affiliate of any of the foregoing) of the Company to the Company or the Company’s shareholders, (iii) any action asserting a claim arising pursuant to any provision of the Delaware General Corporation Law or the Company’s Certificate of Incorporation or Bylaws, or (iv) any other action asserting a claim arising under, in connection with, and governed by the internal affairs doctrine.

I, THE UNDERSIGNED, being the incorporator hereinbefore named, for the purpose of forming a corporation pursuant to the Delaware General Corporation Law, do make this certificate, hereby declaring and certifying that this is my act and deed and the facts herein stated are true, and accordingly have hereunto set my hand this 21st day of November, 2014.
