(B) Notwithstanding the foregoing, the Corporation shall indemnify a person entitled to indemnification under subsection (A) above in connection with a Proceeding (or any part of a Proceeding) initiated, or to be initiated, by an indemnified person only if authorization for the Proceeding (or any part of a Proceeding) was not denied by the Board of Directors of the Corporation within 30 days after receipt of notice of such Proceeding from the indemnified person.

(C) Notwithstanding anything in this Agreement, the Corporation’s obligations under these indemnification provisions shall not apply to: (i) a medical malpractice claim or matter; (ii) acts or omissions in contravention of a director’s or officer’s written agreement with the Corporation including without limitation, failure to substantially abide by policies and procedures in the manner described in a director’s or officer’s written agreement with the Corporation; (iii) acts or omissions which are known, or should reasonably be known, to be unlawful by the director or officer and which were not the result of the Corporation’s direction or within the scope of service as a director or officer; and (iv) any act or omission occurring on or before December 31, 2012.

Section 2 – Advance of Costs, Charges and Expenses.

Notwithstanding the immediately preceding sentence, in connection with a Proceeding (or any part of a Proceeding) initiated by that person, the Corporation shall pay the costs, charges and expenses in advance of the final disposition of the Proceeding only if authorization for the Proceeding (or any part of a Proceeding) was not denied by the Board of Directors of the Corporation within 30 days after receipt of a request for advancement accompanied by an Undertaking. A person to whom costs, charges. and expenses are advanced pursuant to this Article shall not be obligated to repay pursuant to the Undertaking until the final determination of: (a) the pending Proceeding in a court of competent jurisdiction concerning the right of that person to be indemnified; or, (b) the obligation of the person to repay pursuant to the Undertaking. The Board of Directors may, upon approval of the indemnified person, authorize the Corporation’s counsel to represent the person in any action, suit or proceeding, whether or not the Corporation is a party to that action, suit or proceeding.

Section 3 – Procedure for Indemnification; Conduct or Defense and Counsel. Any indemnification or advance under this Article

shall be made promptly and, in any event, within 60 days after delivery of the written request of the director or officer. The right to indemnification or advances as granted by this Article shall be enforceable by the director or officer in any court of competent jurisdiction if the Corporation denies the request under this Article in whole or in part, or if no disposition of the request is made within the 60-day period after delivery of the request. The requesting person’s costs and expenses incurred in connection with: successfully establishing his right, to indemnification, in whole or in part in any action shall also be indemnified by the Corporation. There shall be a defense available to the Corporation to assert in any action that indemnification is prohibited by law or that the claimant has not met the standard of conduct, if any, required by current legislation or by current judicial or administrative decisions for indemnification. The Corporation shall have the continuing right to approval any counsel chosen to defend the indemnitee, which approval shall not be unreasonably withheld and any settlement of the matter being Indemnified by the Corporation shall require the Corporation’s prior written approval, which shall not be unreasonably withheld. If the Corporation and the indemnitee are part of the same Proceeding, then to the extent that the applicable rules of professional responsibilities permit the Corporation and the indemnitee to be represented by the same legal counsel, as the Corporation shall reasonably determine, then the Corporation shall choose counsel and direct the defense and settlement of any such Proceeding, provided that any settlement fully concludes the matter and forecloses any further liability for the indemnitee arising out of or relating to that Proceeding to the extent indemnification applies under this Article.

The Corporation shall have all of the powers and privileges, and shall be subject to all of the limitations and restrictions; now or hereafter granted to or imposed on Corporations organized for the purpose of rendering the professional services hereinabove designated by the Professional Service Corporation Act of the State of New Jersey, and other applicable laws of the State of New Jersey.

after the same shall have been approved as provided in the Bylaws of the Corporation or in any agreement among the shareholders.
