SEVENTH. Except as otherwise fixed by resolution of the Board of Directors pursuant to the provisions of Article FOURTH hereof relating to the rights of the holders of Preferred Stock to elect directors as a class, the number of the directors of the Corporation shall be fixed from time to time by resolution of the Board of Directors. The directors, other than those who may be elected by the holders of Preferred Stock, shall be classified, with respect to the time for which they severally hold office, into three classes, as nearly equal in number as possible, designated Class I, Class II and Class III. The directors in Class I shall serve for an initial term expiring at the Corporation’s 2016 annual meeting of stockholders, the directors in Class II shall serve for an intial term expiring at the Corporation’s 2017 annual meeting of stockholders, and the directors in Class III shall serve for an intial term expiring at the Corporation’s 2018 annual meeting of stockholders, with each director in a class to hold office until his successor is elected and qualified. At the 2016 annual meeting of the stockholders of the Corporation and at each subsequent annual meeting of the stockholders of the Corporation, the successors of the class of directors whose term expires at that meeting shall be elected to hold office for a term expiring at the annual meeting of stockholders held in the third year following the year of their election. Advance notice of stockholder nominations for the election of directors shall be given in the manner provided in the By-Laws of the Corporation.

Any director elected in accordance with the preceding sentence shall be a member of the class of directors in which the new directorship was created (subject to the requirements of this Article SEVENTH that all classes be as nearly equal in number as possible) or in which the vacancy occurred and shall be submitted to a stockholder vote at the next annual meeting of stockholders.

No decrease in the number of directors constituting the Board of Directors shall shorten the term of an incumbent director.

Subject to the rights of the holders of Preferred Stock to elect directors as a class, a director may be removed only for cause and only by the affirmative vote of the holders of 80% of the combined voting power of the then outstanding shares of stock entitled to vote generally in the election of directors, voting together as a single class.

In furtherance and not in limitation of the powers conferred by statute, the Board of Directors is expressly authorized:

1. To adopt, amend and repeal the By-Laws of the Corporation. Any by-laws adopted by the directors under the powers conferred hereby may be amended or repealed by the directors or by the stockholders. Notwithstanding any provision in this Amended and Restated Certificate of Incorporation or the By-Laws of the Corporation to the contrary, Article II, Sections 3 and 7 and Article III, Sections 1, 2 and 3 of the By-Laws of the Corporation shall not be amended or repealed by the stockholders and no provision inconsistent therewith shall be adopted by the stockholders, in each case without the affirmative vote of the holders of at least 80% of the voting power of all the shares of the Corporation entitled to vote generally in the election of directors, voting together as a single class.

2. To fix and determine, and to vary the amount of, the working capital of the Corporation, and to determine the use or investment of any assets of the Corporation, to set apart out of any of the funds of the Corporation available for dividends a reserve or reserves for any proper purpose and to abolish any such reserve or reserves.

5. To authorize the sale, lease or other disposition of any part or parts of the properties of the Corporation and to cease to conduct the business connected therewith or again to resume the same, as it may deem best.

6. To authorize the borrowing of money, the issuance of bonds, debentures and other obligations or evidences of indebtedness of the Corporation, secured or unsecured, and the inclusion of provisions as to redeemability and convertibility into shares of stock of the Corporation or otherwise; and the mortgaging or pledging, as security for money borrowed or bonds, notes, debentures or other obligations issued by the Corporation, of any property of the Corporation, real or personal, then owned or thereafter acquired by the Corporation.

In addition to the powers and authorities herein or by statute expressly conferred upon it, the Board of Directors may exercise all such powers and do all such acts and things as may be exercised or done by the Corporation, subject, nevertheless, to the provisions of the laws of the

State of Delaware, of this Amended and Restated Certificate of Incorporation and of the By-Laws of the Corporation.

Subject to any limitation in the By-Laws of the Corporation, the members of the Board of Directors shall be entitled to reasonable fees, salaries or other compensation for their services, as determined from time to time by the Board of Directors, and to reimbursement for their expenses as such members. Nothing herein contained shall preclude any director from serving the Corporation or its subsidiaries or affiliates in any other capacity and receiving compensation therefor.

Notwithstanding anything contained in this Amended and Restated Certificate of Incorporation to the contrary, the affirmative vote of the holders of at least 80% of the voting power of all shares of the Corporation entitled to vote generally in the election of directors, voting together as a single class, shall be required to alter, amend, adopt any provision inconsistent with or repeal this Article SEVENTH.

EIGHTH. Both stockholders and directors shall have power, if the By-Laws of the Corporation so provide, to hold their meetings and to have one or more offices within or without the State of Delaware.

Except as otherwise fixed by resolution of the Board of Directors pursuant to the provisions of Article FOURTH hereof relating to the rights of the holders of Preferred Stock, any action required or permitted to be taken by the stockholders of the Corporation must be effected at a duly called annual or special meeting of such holders and may not be effected by any consent in writing by such holders. Except as otherwise required by law and subject to the rights of the holders of Preferred Stock, special meetings of stockholders may be called only by the Chairman on his own initiative, the President on his own initiative or by the Board of Directors pursuant to a resolution approved by a majority of the entire Board of Directors. Notwithstanding anything contained in this Amended and Restated Certificate of Incorporation to the contrary, the affirmative vote of the holders of at least 80% of the voting power of all shares of the Corporation entitled to vote generally in the election of directors, voting together as a single class, shall be required to alter, amend, adopt any provision inconsistent with or repeal this Article EIGHTH.

NINTH. Whenever a compromise or arrangement is proposed between the Corporation and its creditors or any class of them and/or between the Corporation and its stockholders or any class of them, any court of equitable jurisdiction within the State of Delaware may, on the application in a summary way of the Corporation or of any creditor or stockholder thereof, or on the application of any receiver or receivers appointed for the Corporation under the provisions of Section 291 of the General Corporation Law of the State of Delaware or on the application of trustees in dissolution or of any receiver or receivers appointed for the Corporation under the provisions of Section 279 of the General Corporation Law of the State of Delaware order a meeting of the creditors or class of creditors, and/or of the stockholders or class of stockholders of the Corporation, as the case may be, to be summoned in such manner as the said court directs. If a majority in number representing three-fourths in value of the creditors or class of creditors, and/or of the stockholders or class of stockholders of the Corporation, as the case may be, agree

to any compromise or arrangement and to any reorganization of the Corporation as consequence of such compromise or arrangement, the said compromise or arrangement and the said reorganization shall, if sanctioned by the court to which the said application has been made, be binding on all the creditors or class of creditors, and/or on all the stockholders or class of stockholders, of the Corporation, as the case may be, and also on the Corporation.

TENTH. Except as otherwise provided in this Amended and Restated Certificate of Incorporation, the Corporation reserves the right to amend, alter, change or repeal any provision contained in this Amended and Restated Certificate of Incorporation, in the manner now or hereafter prescribed by statute, and all rights conferred upon stockholders herein are granted subject to this reservation.

ELEVENTH. No contract or other transaction between the Corporation and any person, firm, association or Corporation and no other act of the Corporation shall, in the absence of fraud, be invalidated or in any way affected by the fact that any of the directors of the Corporation are, directly or indirectly, pecuniarily or otherwise interested in such contract, transaction or other act or related to or interested in such person, firm, association or corporation as director, stockholder, officer, employee, member or otherwise. Any director of the Corporation individually, or any firm or association of which any director may be a member, may be a party to, or may be pecuniarily or otherwise interested in, any contract or transaction of the Corporation, provided that the fact that he individually or such firm or association is so interested shall be disclosed or known to the Board of Directors or a majority of such members thereof as shall be present at any meeting of the Board of Directors, or of any committee of directors having the powers of the full Board, at which action upon any such contract, transaction or other act is taken, and if such fact shall be so disclosed or known any director of the Corporation so related or otherwise interested may be counted in determining the presence of a quorum at any meeting of the Board of Directors or of such committee at which action upon any such contract, transaction or act shall be taken and may vote thereat with respect to such action with like force and effect as if he were not so related or interested. Any director of the Corporation may vote upon any contract or other transaction between the Corporation and any subsidiary or affiliated corporation without regard to the fact that he is also a director of such subsidiary or affiliated corporation.

TWELFTH.

(a) A director 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, except for liability (i) for any breach of the director’s duty of loyalty to the Corporation or its stockholders, (ii) for acts or omissions not in good faith or which involve intentional misconduct or a knowing violation of law, (iii) under Section 174 of the General Corporation Law of the State of Delaware, or (iv) for any transaction from which the director derived an improper personal benefit. If the General Corporation Law of the State of Delaware, or any other applicable law, is amended to authorize corporate action further eliminating or limiting the personal liability of directors, then the liability of a director of the Corporation shall be eliminated or limited to the fullest extent permitted by the General Corporation Law of the State of Delaware, or any other

applicable law, as so amended. Any repeal, or modification of this Section (a) by the stockholders of the Corporation shall not adversely affect any right or protection of a director of the Corporation existing at the time of such repeal or modification.

(b)

(1) Each person who was or is made a party or is threatened to be made a party to or is involved in any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (hereinafter a “proceeding”), by reason of the fact that he or she or a person of whom he or she is the legal representative is or was a director or officer of the Corporation or is or was serving at the request of the Corporation as a director, officer or employee or agent of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to employee benefit plans, whether the basis of such proceeding is alleged action in an official capacity as a director, officer, employee or agent or in any other capacity while serving as a director, officer, employee or agent, shall be indemnified and held harmless by the Corporation to the fullest extent authorized by the General Corporation Law of the State of Delaware, or any other applicable 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 Corporation to provide broader indemnification rights than said law permitted the Corporation 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 or to be paid in settlement) reasonably incurred or suffered by such person in connection therewith and such indemnification shall continue as to a person who has ceased to be a director, officer, employee or agent and shall inure to the benefit of his or her heirs, executors and administrators; provided, however, that except as provided in paragraph (2) of this Section (b) with respect to proceedings seeking to enforce rights to indemnification, the Corporation shall indemnify any such person seeking indemnification in connection with a proceeding (or part thereof) initiated by such person only if such proceeding (or part thereof) was authorized by the Board of Directors. The right to indemnification conferred in this Section (b) shall be a contract right and shall include the right to be paid by the Corporation the expenses incurred in defending any such proceeding in advance of its final disposition; provided, however, that if the General Corporation Law of the State of Delaware, or any other applicable law, requires, the payment of such expenses incurred by a director or officer in his or her capacity as a director or officer (and not in any other capacity in which service was or is rendered by such person while a director or officer, including, without limitation, service to an employee benefit plan) in advance of the final disposition of a proceeding, shall be made only upon delivery to the Corporation of an undertaking by or on behalf of such director or officer, to repay all amounts so advanced if it shall ultimately be determined that such director or officer is not entitled to be indemnified under this Section (b) or otherwise.

(2) If a claim under paragraph (1) of this Section (b) is not paid in full by the Corporation within thirty days after a written claim has been received by the Corporation, the claimant may at any time thereafter bring suit against the Corporation to recover the unpaid amount of the claim and, if successful in whole or in part, the claimant shall be entitled to be paid also the expense of prosecuting such claim. It shall be a defense to any such action (other than an action brought to enforce a claim for expenses incurred in defending any proceeding in advance of its final disposition where the required undertaking, if any is required, has been tendered to the Corporation) that the claimant has not met the standards of conduct which make it permissible under the General Corporation Law of the State of Delaware, or any other applicable law, for the Corporation to indemnify the claimant for the amount claimed, but the burden of proving such defense shall be on the Corporation. Neither the failure of the Corporation (including its Board of Directors, stockholders or independent legal counsel) to have made a determination prior to the commencement of such action that indemnification of the claimant is proper in the circumstances because he or she has met the applicable standard of conduct set forth in the General Corporation Law of the State of Delaware, or any other applicable law, nor an actual determination by the Corporation (including its Board of Directors, stockholders or independent legal counsel) that the claimant has not met such applicable standard of conduct, shall be a defense to the action or create a presumption that the claimant has not met the applicable standard of conduct.

(3) The right to indemnification and the payment of expenses incurred in defending a proceeding in advance of its final disposition conferred in this Section (b) shall not be exclusive of any other right which any person may have or hereafter acquire under any statute, provision of this Amended and Restated Certificate of Incorporation, By-Law, agreement, vote of stockholders or disinterested directors or otherwise.

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

(5) The Corporation may, to the extent authorized from time to time by the Board of Directors, grant rights to indemnification, and rights to be paid by the Corporation the expenses incurred in defending any proceeding in advance of its final disposition, to any employee or agent of the Corporation to the fullest extent of the provisions of this Section (b) with respect to the indemnification and advancement of expenses of directors and officers of the Corporation.

(6) Any repeal or modification of this Section (b) by the stockholders of the Corporation shall not adversely affect any right or protection of a director,

officer, employee or agent of the Corporation existing at the time of such repeal or modification.

THIRTEENTH. Unless the Corporation consents in writing to the selection of an alternative forum, to the fullest extent permitted by law, the sole and exclusive forum for (a) any derivative action or proceeding brought on behalf of the Corporation, (b) any action asserting a claim of breach of a fiduciary duty owed by any director, officer or other employee of the Corporation to the Corporation or the Corporation’s stockholders, (c) any action asserting a claim against the Corporation or any director or officer or other employee of the Corporation arising pursuant to the General Corporation Law of the State of Delaware or the Corporation’s certificate of incorporation or by-laws (as either may be amended from time to time), or (d) any action asserting a claim governed by the internal affairs doctrine of the State of Delaware shall be a state court located within the State of Delaware (or, if no state court located within the State of Delaware has jurisdiction, the federal district court for the District of Delaware). Any person or entity purchasing or otherwise acquiring 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 THIRTEENTH.

IN WITNESS WHEREOF, this Amended and Restated Certificate of Incorporation, which restates and integrates and further amends the provisions of the Certificate of Incorporation of the Corporation, and which has been duly adopted in accordance with Sections 242 and 245 of the General Corporation Law of the State of Delaware, has been executed by its duly authorized officer as of September 22, 2015.
