TENTH: This Article is inserted for the management of the business and for the conduct of the affairs of the Corporation. 1. Number of Directors. The number of directors of the Corporation shall not be less than three (3) nor more than seven (7). The exact number of directors within the limitations specified in the preceding sentence shall be fixed from time to time by, or in the manner provided in, the Corporation's By-Laws. 2. Classes of Directors. The Board of Directors shall be and is divided into three classes: Class I, Class II and Class III. No one class shall have more than one director more than any other class. If a fraction is contained in the quotient arrived at by dividing the designated number of directors by three, then, if such fraction is one-third, the extra director shall be a member of Class I, and if such fraction is two-thirds, one of the extra directors shall be a member of Class I and one of the extra directors shall be a member of Class II, unless otherwise provided from time to time by resolution adopted by the Board of Directors. 3. Election of Directors. Elections of directors must be by written ballot. 4. Terms of Office. Each director shall serve for a term ending on the date of the third annual meeting following the annual meeting at which such director was elected; provided, that each initial director in Class I shall serve for a term ending on the date of the annual meeting in 1997; each initial director in Class II shall serve for a term ending on the date of the annual meeting in 1998; and each initial director in Class III shall serve for a term ending on the date of the annual meeting in 1999; and provided further, that the term of each director shall be subject to the election and qualification of his successor and to his earlier death, resignation or removal. 5. Allocation of Directors Among Classes in the Event of Increases or Decreases in the Number of Directors. In the event of any increase or decrease in the authorized number of directors, (i) each director then serving as such shall nevertheless continue as a director of the class of which he is a member and (ii) the newly created or eliminated directorships resulting from such increase or decrease shall be apportioned by the Board of Directors among the three classes of directors so as to ensure that no one class has more than one director more than any other class. To the extent possible, consistent with the foregoing rule, any newly created directorships shall be added to those classes whose terms of office are to expire at the latest dates following such allocation, and any newly eliminated directorships shall be subtracted from those classes whose terms of offices are to expire at the earliest dates following such allocation, unless otherwise provided from time to time by resolution adopted by the Board of Directors. 6. Quorum; Action at Meeting. A majority of the directors at any time in office shall constitute a quorum for the transaction of business. In the event one or more of the directors shall be disqualified to vote at any meeting, then the required quorum shall be reduced by one for each director so disqualified, provided that in no case shall less than one-third of the number of directors fixed pursuant to Section 1 above constitute a quorum. If at any meeting of the Board of Directors there shall be less than such a quorum, a majority of those present may adjourn the meeting from time to time. Every act or decision done or made by a majority of the directors present at a meeting duly held at which a quorum is present shall be regarded as the act of the Board of Directors unless a greater number is required by law, by the By-Laws of the Corporation or by this Restated Certificate of Incorporation. 7. Resignation; Removal. Any director may resign at any time upon written notice to the attention of the secretary of the corporation. Directors of the Corporation may be removed only for cause by the affirmative vote of the holders of at least two-thirds of the shares of the capital stock of the Corporation issued and outstanding and entitled to vote. 8. Vacancies. Any vacancy in the Board of Directors, however occurring, including a vacancy resulting from an enlargement of the board, shall be filled only by a vote of a majority of the directors then in office, although less than a quorum, or by a sole remaining director. A director elected to fill a vacancy shall be elected to hold office until the next election of the class for which such director shall have been chosen, subject to the election and qualification of his successor and to his earlier death, resignation or removal. 9. Amendments to Article. Notwithstanding any other provisions of law, this Restated Certificate of Incorporation or the By-Laws of the Corporation, each as amended, and notwithstanding the fact that a lesser percentage may be specified by law, the affirmative vote of the holders of at least seventy-five percent (75%) of the shares of capital stock of the Corporation issued and outstanding and entitled to vote shall be required to amend or repeal, or to adopt any provision inconsistent with, this Article TENTH. ELEVENTH. Stockholders of the Corporation may not take any action by written consent in lieu of a meeting.

Business transacted at any special meeting of stockholders shall be limited to matters relating to the purpose or purposes stated in the notice of meeting. Notwithstanding any other provision of law, this Restated Certificate of Incorporation or the By-Laws of the Corporation, each as amended, and notwithstanding the fact that a lesser percentage may be specified by law, the affirmative vote of the holders of at least seventy-five percent (75%) of the shares of capital stock of the Corporation issued and outstanding and entitled to vote shall be required to amend or repeal, or to adopt any provisions inconsistent with, this Article TWELFTH. THIRTEENTH. In anticipation that the Corporation may enter into contracts or otherwise transact business with entities in which any directors of the Corporation own a financial interest ("Related Entities"), the provisions of this Article THIRTEENTH are set forth to regulate and guide such contracts or other business. These provisions are in addition to, and not in limitation of, the provisions of the General Corporation Law and the other provisions of this Restated Certificate of Incorporation. Any contract or other business that does not comply with the procedures set forth in this Article THIRTEENTH shall not by reason thereof be deemed void or voidable or result in any breach of any duty or the derivation of any improper personal benefit by any person but shall be governed by the provisions of this Restated Certificate of Incorporation, the By-laws of the Corporation, the General Corporation Law and other applicable law. No contract, agreement, arrangement or transaction between the Corporation and a Related Entity (a "Related Transaction") shall be void or voidable solely for the reason that such persons or entities are parties thereto, if: (i) the material facts of the Related Transaction are disclosed or are known to the Board of Directors of the Corporation (or a committee thereof) and such board (or committee) in good faith authorizes, approves or ratifies the Related Transaction by the affirmative vote of a majority of the disinterested directors on the Board of Directors (or such committee), even though the disinterested directors may be less than a quorum; (ii) the material facts of the Related Transaction are disclosed or are known to the holders of the then outstanding voting shares of the Corporation entitled to vote thereon, and the Related Transaction is specifically approved or ratified in good faith by the affirmative vote of the holders of a majority of the then outstanding voting shares not owned by the interested directors or Related Entity, as the case may be, even though such holders may be less than a quorum; (iii) such Related Transaction is effected pursuant to and consistent with terms and conditions specified in any arrangements, standards or guidelines that are in good faith authorized, approved or ratified, after disclosure or knowledge of the material facts related thereto, by the affirmative vote of a majority of the disinterested directors on the Board of Directors (or committee thereof), or by the affirmative vote of the holders of a majority of the then outstanding voting shares of the Corporation not owned by the interested directors or Related Entity, as the case may be, even though the disinterested directors or such holders may be less than a quorum; or (iv) The Related Transaction was fair to the Company. In addition, each Related Transaction authorized, approved or effected, and each of such arrangements, standards or guidelines so authorized or approved, as described in (i), (ii) or (iii) above, shall be conclusively deemed to be fair to the Corporation and its stockholders; provided, however, that if such authorization or approval is not obtained, or such Related Transaction is not so effected, no presumption shall arise that such Related Transaction, or such arrangements, standards or guidelines, are not fair to the Corporation and its stockholders. Any person or entity purchasing or otherwise acquiring any interest in any shares of the Corporation shall be deemed to have notice of and to have consented to the provisions of this Article THIRTEENTH.
