The nominating committee shall also make nominations for the directors to be elected by the stockholders of the corporation at an annual meeting of the stockholders as provided in this section.

Only persons nominated in accordance with the procedures set forth in this Section 4 shall be eligible for election as directors at an annual meeting.

No person shall be elected as a director of the corporation unless nominated in accordance with the terms set forth in this Section 4.

Any director may be removed, with cause, at any time, by the affirmative vote by written ballot of 80% of the voting interest of the stockholders of record of the corporation entitled to vote, given at an annual meeting or at a special meeting of the stockholders called for that purpose. The vacancy in the Board of Directors caused by any such removal shall be filled by the Board of Directors as provided in Section 6 of this Article III.

SECTION 6. Vacancies. Vacancies and newly created directorships resulting from any increase in the authorized number of directors may be filled only by a majority of the directors then in office though less than a quorum or by a sole remaining director.

SECTION 2. Prepaid Expenses. Expenses incurred in defending a civil or criminal action, suit or proceeding shall be paid by the corporation as incurred and in advance of the final disposition of such action, suit or proceeding, provided the party undertakes in writing (in form

and substance reasonably satisfactory to the corporation) to repay the amount paid or reimbursed if it is ultimately determined that such party is not entitled to indemnification for such expenses. [amended 9/7/2000]

SECTION 3. Insurance.

SECTION 4. Mergers. For purposes of this Article VI, references to “the corporation” shall include, in addition to the resulting or surviving corporation, constituent corporations (including any constituent of a constituent) absorbed in a consolidation or merger that, if its separate existence had continued, would have had power and authority to indemnify its directors, officers, employees or agents, so that any person who is or was a director, officer, employee or agent of such constituent corporation or is or was serving at the request of such constituent corporation as a director, officer, employee or agent of another corporation, partnership, joint venture, trust or other enterprise shall stand in the same position under the provisions of this Article VI with respect to the resulting or surviving corporation as he would have with respect to such constituent corporation if its separate existence had continued.

ARTICLE VII

CAPITAL STOCK

SECTION 1. Certificates. The board of directors may provide by resolution that some or all of any or all classes or series of its stock will be uncertificated shares. However, any such resolution will not apply to shares represented by a certificate until that certificate is surrendered to the corporation. Every holder of stock in the corporation represented by certificates shall be entitled to have a certificate, signed by, or in the name of the corporation by, the chairman of the board, the chief executive officer, the chief financial officer, the president or a vice president and by the secretary or an assistant secretary of the corporation, certifying the number of shares owned by him in the corporation. If the corporation shall be authorized to issue more than one class of stock or more than one series of any class, the powers, designations, preferences and relative, participating, option or other special rights of each class of stock or series thereof and the qualifications, limitations or restrictions of such preferences or rights shall be set forth in full or summarized on the face or back of the certificate that the corporation shall issue to represent such class or series of stock; provided, that, except as otherwise provided in Section 202 of the General Corporation Law of the State of Delaware, in lieu of the foregoing requirements, there may be set forth on the face or back of the certificate that the corporation shall issue to represent such class or series of stock a statement that the corporation will furnish without charge to each stockholder who so requests the powers, designations, preferences and relative, participating, optional or other special rights of each class of stock or series thereof and the qualifications, limitations or restrictions of such preferences or rights.

SECTION 2. Facsimile Signatures. Any or all of the signatures on the certificate may be facsimile. In case any officer, transfer agent or registrar who has signed or whose facsimile signature has been placed upon a certificate shall have ceased to be such officer, transfer agent or registrar before such certificate is issued, it may be issued by the corporation with the same effect as if he were such officer, transfer agent or registrar at the date of issue.

SECTION 3. Replacement of Lost, Stolen or Destroyed Certificates. The board of directors may direct a new certificate or certificates of stock or uncertificated shares to be issued in place of any certificate or certificates of stock theretofore issued by the corporation and alleged to have been lost, stolen or destroyed, upon the making of an affidavit of that fact by the person claiming the certificate of stock to be lost, stolen or destroyed. When authorizing such issue of a new certificate or certificates, the board of directors may, in its discretion and as a condition precedent to the issuance thereof, require the owner of such lost, stolen or destroyed certificate or certificates, or his legal representative, to advertise the same in such manner as it shall require or to give the corporation a bond in such sum as it may direct as indemnity against any claim that may be made against the corporation with respect to the certificate alleged to have been lost, stolen or destroyed or the issuance of such new certificate of stock or uncertificated shares. [amended 6/1/2006]

SECTION 4. Transfers. Upon surrender to the corporation or the transfer agent of the corporation of a certificate for shares duly endorsed or accompanied by proper evidence of succession, assignation or authority to transfer, it shall be the duty of the corporation, subject to any proper restrictions on transfer, to issue a new certificate to the person entitled thereto, cancel the old certificate and record the transaction upon its books. Upon receipt of proper transfer instructions from the registered owner of uncertificated shares, such uncertificated shares will be cancelled and issuance of new equivalent uncertificated shares or certificated shares will be made to the person entitled thereto and the transaction will be recorded upon the books of the corporation. [amended 6/1/2006]

SECTION 5. Record Date.

SECTION 6. Registered Stockholders. The corporation shall be entitled to recognize the exclusive right of a person registered on its books as the owner of shares to receive dividends and to vote as such owner, and shall not be bound to recognize any equitable or other claim to or interest in such share or shares on the part of any other person, whether or not provided by the laws of the State of Delaware.
