NINTH: No director shall be personally liable to the Corporation or any of its stockholders for monetary damages for breach of fiduciary duty as a director, except to the extent that such elimination of liability is not permitted under the General Corporation Law of the State of Delaware (the “Delaware Code”) as in effect at the time of the alleged breach of duty.

TENTH: (A) The Corporation shall indemnify and hold harmless, to the fullest extent permitted by the General Corporation Law of the State of Delaware, each director or officer of the Corporation who was or is, or is threatened to be made, a party to or otherwise involved in any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (a “Proceeding”), by reason of the fact that such person is or was a director, officer, employee or agent of the Corporation, or a trustee, custodian, administrator, committeeman or fiduciary of any employee benefit plan, or a person serving another corporation, partnership, joint venture, trust, other enterprise or nonprofit entity in any of the foregoing capacities at the request of the Corporation (an “Authorized Representative”), against all expenses (including attorneys’ fees and disbursements), judgments, fines (including excise and taxes) and amounts paid in settlement actually and reasonably incurred by such person in connection with such Proceeding, whether the basis of such person’s involvement in the Proceeding is an alleged act or omission in such person’s capacity as an Authorized Representative or in another capacity while serving in such capacity or both. The Corporation shall be required to indemnify an incumbent or former director or officer in connection with a Proceeding initiated by such person only if and to the extent that such Proceeding was authorized by the Board of Directors of the Corporation or is a civil suit by such person to enforce rights to indemnification or advancement of expenses.

(B) The Corporation shall promptly pay all expenses (including attorneys’ fees and disbursements) actually and reasonably incurred by a director or officer of the Corporation in defending or appearing (otherwise than as a plaintiff) in any Proceeding described in Paragraph (A) of this Article in advance of the final disposition of such Proceeding upon receipt of a reasonably satisfactory undertaking by or on behalf of such person to repay all amounts so advanced if it shall ultimately be determined by a final, unappealable judicial decision that such person is not entitled to be indemnified for such expenses under this Article or otherwise.

(C) The Corporation shall have the power to, and may, indemnify any person who is or was an Authorized Representative (other than an officer or director who are covered by (A) above) against loss, liability and expense in connection with a Proceeding, and may pay expenses incurred by such person in connection with such Proceeding in advance of the final disposition of the Proceeding, to the fullest extent permitted by law.

(D) The rights to indemnification and advancement of expenses provided by or granted pursuant to this Article shall be presumed to have been relied upon by directors and officers of the Corporation in serving or continuing to serve the Corporation, shall continue as to a person who ceases to be an Authorized Representative, shall inure to the benefit of the heirs, executors and administrators of such person, and shall be enforceable as contract rights. Such rights shall not be deemed exclusive of any other rights to which a person seeking indemnification

or advancement of expenses may be entitled under any statute, agreement, vote of stockholders or disinterested directors, or otherwise, both as to action in such person’s official capacity and as to action in another capacity while holding such office or position. The Corporation may enter into contracts to provide any Authorized Representative with specific rights to indemnification and advancement of expenses, which contracts may confer rights and protections to the maximum extent permitted by law. The Corporation may purchase and maintain insurance, borrow money, create trust funds, pledge, mortgage, or create security interests in the assets of the Corporation, obtain letters of credit, or use other means from time to time to ensure payment of such amounts as may be necessary to perform the Corporation’s obligations provided for in this Article or in any such contract. The by-laws of the Corporation may contain additional provisions implementing and supplementing the provisions of this Article.

(E) Any amendment, modification or repeal of this Article shall not adversely affect any right or protection of a director or officer of the Corporation with respect to any act or omission occurring prior to the time of such amendment, modification or repeal.

ELEVENTH: 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 §291 of Title 8 of the Delaware Code or on the application of trustees in dissolution or of any receiver or receivers appointed for the Corporation under §279 of Title 8 of the Delaware Code 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.
