(a) Subject to the provisions of these by-laws, the Certificate of Incorporation and Delaware Law as to the vote that is required for a specified action, the presence in person or by proxy of the holders of a majority of the outstanding shares of the corporation entitled to vote at any meeting of stockholders shall constitute a quorum for the transaction of business. The vote of the holders of a majority of the shares of the corporation’s stock entitled to vote on the proposal, present in person or represented by proxy, shall be binding on all stockholders of the corporation, unless the vote of a greater number or voting by classes is required by law or the Certificate of Incorporation or these by-laws.

The number of inspectors shall be either one or three. If appointed at the meeting upon the request of one or more stockholders or proxies, the vote of the holders of a majority of shares present shall determine whether one or three inspectors are appointed. In any case any person appointed as an inspector fails to appear or fails or refuses to act, the vacancy may be filled by appointment made by the directors in advance of the convening of the meeting or at the meeting by the person acting as chairman.

If there are three inspectors of election, the decision, act or certificate of a majority is effective in all respects as the decision, act or certificate of all. If no inspectors of election are appointed, the secretary shall pass upon all questions and shall have all other duties specified in this Section 9.

(c) Upon request of the chairman of the meeting or any stockholder or stockholder’s proxy, the inspector(s) of election shall make a report in writing of any challenge or question or other matter determined by the inspector(s) and shall execute a certificate of any fact found in connection therewith. Any such report or certificate shall be filed with the record of the meeting.

ARTICLE VII

INDEMNIFICATION AND INSURANCE

SECTION 1. DEFINITIONS. For the purposes of this Article VII the following definitions shall apply:

“Agent” means any person who: (i) is or was a director, officer, employee, or other agent of this corporation; or (ii) is or was serving at the request of this corporation as a director, officer, employee, or agent of another foreign or domestic corporation, partnership, joint venture, trust or other enterprise (“enterprise”).

“Proceeding” means any threatened, pending or completed action suit or proceeding, whether civil, criminal, administrative, or investigative and whether internal or external to the corporation.

“Expenses” includes, without limitation, attorneys’ fees and any expenses of establishing a right to indemnification under this Article VII.

“Losses” mean the total amount which the agent becomes legally obligated to pay in connection with any proceeding, including judgments, fines, amounts paid in settlement and Expenses.

SECTION 2. THIRD PARTY ACTIONS. The corporation shall indemnify any person who was or is a party or is threatened to be made a party to, or otherwise becomes involved in, any Proceeding (other than an action by or in the right of the corporation) by reason of the fact that the person is or was an Agent of the corporation against Losses actually and reasonably incurred by the person in connection with such Proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal Proceeding, had no reasonable cause to believe the person’s conduct was unlawful. The termination of any Proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in such a manner which the person reasonably believed to be in or not opposed to the best interests of the corporation, and, with respect to any criminal Proceeding, had reasonable cause to believe that the person’s conduct was unlawful.

SECTION 3. ACTIONS BY OR IN THE RIGHT OF THE CORPORATION. The corporation shall indemnify any person who was or is a party or is threatened to be made a party to, or otherwise becomes involved in, any Proceeding by or in the right of the corporation to procure a judgment in its favor by reason of the fact that the person is or was an Agent of the corporation against Expenses actually and reasonably incurred by the person in connection with the defense or settlement of such Proceeding if the person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the corporation and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged by a court of competent jurisdiction to be liable to the corporation unless and only to the extent that the court in which such Proceeding was brought shall determine upon application that, in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such Expenses as the court shall deem proper.

 

SECTION 4. SUCCESSFUL DEFENSE. To the extent that an Agent of the corporation has been successful on the merits or otherwise in defense of any Proceeding referred to in Sections 2 and 3 of this Article VII, or in defense of any claim, issue or matter therein, he or she must be indemnified against Expenses actually and reasonably incurred by him or her in connection therewith.

SECTION 5. DETERMINATION OF CONDUCT. Any indemnification under Sections 2 and 3 of this Article VII, (unless ordered by a court or advanced pursuant to Section 6 of this Article VII) shall be made by the corporation only as authorized in the specific case upon a determination that indemnification of the Agent is proper in the circumstances because he or she has met the applicable standard of conduct set forth in Sections 2 and 3 of this Article VII. Such determination shall be made (a) by the board of directors by a majority vote of a quorum consisting of directors who were not parties to such Proceeding, or (b) if such a quorum is not obtainable or, even if obtainable, a quorum of disinterested directors so directs, by independent legal counsel in a written opinion, or (c) if a majority vote of a quorum consisting of directors who were not parties to the Proceeding so orders, by independent legal counsel in a written opinion, or (d) by the stockholders.

SECTION 6. PAYMENT OF EXPENSES IN ADVANCE. Expenses incurred by an Agent in connection with a Proceeding shall be paid by the corporation as they are incurred and in advance of the final disposition of such Proceeding upon receipt of an undertaking by or on behalf of such Agent to repay such amount if it shall ultimately be determined by a court of competent jurisdiction that he or she is not entitled to be indemnified by the corporation as authorized in this Article VII.

SECTION 7. INDEMNITY NOT EXCLUSIVE. The indemnification and advancement of Expenses provided by, or granted pursuant to, the other provisions of this Article VII shall not be deemed exclusive of any other rights to which a person seeking indemnification or advancement of Expenses may be entitled under any by-law, agreement, vote of stockholders or disinterested directors, or otherwise, both as to action in his or her official capacity and as to action in another capacity while holding such office.

SECTION 8. INSURANCE INDEMNIFICATION. The corporation shall have the power to purchase and maintain insurance on behalf of any person who is or was an Agent of the corporation against any liability asserted against the person and incurred by the person in any such capacity, or arising out of the person’s status as such, whether or not the corporation would have the power to indemnify the person against such liability under the provisions of this Article VII.

SECTION 9. HEIRS, EXECUTORS AND ADMINISTRATORS. The indemnification and advancement of Expenses provided by, or granted pursuant to, this Article VII shall, unless otherwise provided when authorized or ratified, continue as to a person who has ceased to be an Agent and shall inure to the benefit of the heirs, executors and administrators of such a person.

SECTION 10. FURTHER AMENDMENT. Notwithstanding any provision in this Article VII to the contrary, in the event the Delaware Law is either amended to provide, or interpreted by judicial or other binding legal decision to provide, broader indemnification rights than those contained herein, such broader indemnification rights shall be provided to any and all persons entitled to be indemnified pursuant to the Delaware Law the intent of this provision being to permit the corporation to indemnify, to the full extent permitted by Delaware Law, persons whom it may indemnify thereunder.
