SEVENTH: To the fullest extent permitted by the DGCL as it now exists or may hereafter be amended, no director or officer of the Corporation shall be personally liable to the Corporation or its stockholders for monetary damages for breach of fiduciary duty owed to the Corporation or its stockholders. Neither the amendment nor repeal of this Article SEVENTH, nor the adoption of any provision of this Certificate of Incorporation, nor, to the fullest extent permitted by the DGCL, any modification of applicable law shall eliminate, reduce or otherwise adversely affect any right or protection of a current or former director or officer of the Corporation existing at the time of such amendment, repeal, adoption or modification.

EIGHTH: Except as otherwise agreed in writing between such director and the Corporation, or as provided below, to the fullest extent permitted by applicable law, (a) no director of the Corporation shall have any duty (fiduciary or otherwise) or obligation, if any, to refrain from (i) engaging in the same or similar activities or lines of business as the Corporation or any of its subsidiaries or (ii) doing business with any client, customer or vendor of the Corporation or any of its subsidiaries, including, in the cases of clauses (i) or (ii), any such matters as may be Corporate Opportunities (as defined below); and (b) no director shall be deemed to have breached any duty (fiduciary or otherwise), if

NINTH: The Corporation hereby expressly elects not to be governed by Section 203 of the DGCL, and the restrictions contained in Section 203 of the DGCL shall not apply to the Corporation.
