RIGHT TO INDEMNIFICATION. The Company shall indemnify and hold harmless each Indemnitee (as this and all other capitalized words are defined in Section 13 (Definitions) of this Article) to the fullest extent permitted by applicable law as it presently exists or may hereafter be amended. The rights of an Indemnitee provided under the preceding sentence shall include, but not be limited to, the right to be indemnified to the fullest extent permitted by Section 145(b) of the DGCL in Proceedings by or in the right of the Company and to the fullest extent permitted by Section 145(a) of the DGCL in all other Proceedings. SECTION 2. EXPENSES. If an Indemnitee is, by reason of his Corporate Status, a witness in or is a party to any Proceeding, and is successful on the merits or otherwise, he shall be indemnified against all Expenses actually and reasonably incurred by him or on his behalf in connection therewith. If the Indemnitee is a party to and is not wholly successful in such Proceeding but is successful, on the merits or otherwise, as to any Matter in such Proceeding, the Company shall indemnify the Indemnitee against all Expenses actually and reasonably incurred by him or on his behalf relating to each such Matter. The termination of any Matter in such a Proceeding by dismissal, with or without prejudice, shall be deemed to be a successful result as to such Matter. SECTION 3. REQUEST FOR INDEMNIFICATION. To obtain indemnification, an Indemnitee shall submit to the Corporate Secretary of the Company a written request with such information as is reasonably available to the Indemnitee regarding the basis for such claim for indemnification. The Corporate Secretary of the Company shall promptly advise the Board of Directors of such request. An Indemnitee shall be advanced Expenses, within ten days after requesting them, to the fullest extent permitted by Section 145(e) of the DGCL SECTION 4. DETERMINATION OF INDEMNIFICATION. The Indemnitee's entitlement to indemnification shall be determined in accordance with Section 145(d) of the DGCL. If entitlement to indemnification is to be determined by Independent Counsel, the Company shall furnish notice to the Indemnitee within ten days after receipt of the request for indemnification, specifying the identity and address of the Independent Counsel. The Indemnitee may, within 14 days after receipt of such written notice of selection, deliver to the Company a written objection to such selection. Such objection may be asserted only on the ground that the Independent Counsel so selected does not meet the requirements of Independent Counsel and the objection shall set forth with particularity the factual basis of such assertion. If there is an objection to the selection of Independent Counsel, either the Company or the Indemnitee may petition the Court of Chancery of the State of Delaware or any other court of competent jurisdiction for a determination that the objection is without a reasonable basis and/or for the appointment of Independent Counsel selected by the Court. Except in the event that the determination of entitlement to indemnification is to be made by Independent Counsel, if the person or persons authorized under this Section to determine entitlement to indemnification shall not have made and furnished to the Indemnitee in writing a determination of whether the Indemnitee is entitled to indemnification within 30 days after receipt by the Company of the Indemnitee's request therefor, a determination of entitlement to indemnification shall be deemed to have been made, and the Indemnitee shall be entitled to such indemnification unless the Indemnitee knowingly misrepresented a material fact in connection with the request for indemnification or such indemnification is prohibited by law. The termination of any Proceeding or of any Matter therein, by judgment, order, settlement or conviction, or upon a plea of NOLO CONTENDERE or its equivalent, shall not (except as otherwise expressly provided in this Article) of itself adversely affect the right of Indemnitee to indemnification or create a presumption that Indemnitee did not act in good faith and in a manner which he reasonably believed to be in or not opposed to the best interests of the Company, or with respect to any criminal Proceeding, that Indemnitee had reasonable cause to believe that his conduct was unlawful. SECTION 5. PAYMENTS TO INDEPENDENT COUNSEL. The Company shall pay any and all reasonable fees and expenses of Independent Counsel incurred acting pursuant to this Article and in any proceeding to which it is a party or witness in respect of its investigation and written report and shall pay all reasonable fees and expenses incident to the procedures in which such Independent Counsel was selected or appointed. No Independent Counsel may serve if a timely objection has been made to his selection until a court has determined that such objection is without a reasonable basis. SECTION 6. RIGHT TO BRING SUIT. In the event that: (a) a determination is made pursuant to Article V, Section 4 (Determination of Indemnification) that the Indemnitee is not entitled to indemnification under this Article; (b) advancement of Expenses is not timely made pursuant to Section 3 (Request for Indemnification) of this Article; (c) Independent Counsel has not made and delivered a written opinion determining the request for indemnification (i) within 90 days after being appointed by the court, or (ii) within 90 days after objections to his selection have been overruled by the court, or (iii) within 90 days after the time for the Company or the Indemnitee to object to his selection; or (d) payment of indemnification is not made within five days after a determination of entitlement to indemnification; the Indemnitee shall be entitled to an adjudication in an appropriate court of the State of Delaware, or in any other court of competent jurisdiction, of his entitlement to such indemnification or advancement of Expenses. In the event that a determination shall have been made that the Indemnitee is not entitled to indemnification, any judicial proceeding or arbitration commenced pursuant to this Section shall be conducted in all respects as a DE NOVO trial on the merits and Indemnitee shall not be prejudiced by reason of that adverse determination. If a determination shall have been made or deemed to have been made that the Indemnitee is entitled to indemnification, the Company shall be bound by such determination in any judicial proceeding commenced pursuant to this Section 6, or otherwise, unless the Indemnitee knowingly misrepresented a material fact in connection with the request for indemnification, or such indemnification is prohibited by law. The Company shall be precluded from asserting in any judicial proceeding commenced pursuant to this Section 6 that the procedures and presumptions of this Article are not valid, binding and enforceable and shall stipulate in any such court that the Company is bound by all provisions of this Article. In the event that the Indemnitee, pursuant to this Section 6, seeks a judicial adjudication to enforce his rights under, or to recover damages for breach of, this Article, the Indemnitee shall be entitled to recover from the Company, and shall be indemnified by the Company against, any and all Expenses actually and reasonably incurred by him in such judicial adjudication, but only if he prevails therein. If it shall be determined in such judicial adjudication that the Indemnitee is entitled to receive part but not all of the indemnification or advancement of Expenses sought, the Expenses incurred by the Indemnitee in connection with such judicial adjudication or arbitration shall be appropriately prorated. SECTION 7. NONEXCLUSIVITY OF RIGHTS.
