1. Actions, Suits and Proceedings Other than By or In the Right of the Society.
   Each Councilor and Officer shall be indemnified and held harmless by the Society against any and all Expenses and Liabilities that are incurred or paid by such Councilor or Officer or on such Councilor’s or Officer’s behalf in connection with any Proceeding or any claim, issue or matter therein (other than an action by or in the right of the Society), which such Councilor or Officer is, or is threatened to be made, a party to or participant in by reason of such Councilor’s or Officer’s Corporate Status, if such Councilor or Officer acted in good faith and in a manner such Councilor or Officer reasonably believed to be in or not opposed to the best interests of the Society and, with respect to any criminal proceeding, had no reasonable cause to believe his or her conduct was unlawful.


2. Actions, Suits and Proceedings By or In the Right of the Society
   Each Councilor and Officer shall be indemnified and held harmless by the Society against any and all Expenses that are incurred by such Councilor or Officer or on such Councilor’s or Officer’s behalf in connection with any Proceeding or any claim, issue or matter therein by or in the right of the Society, which such Councilor or Officer is, or is threatened to be made, a party to or participant in by reason of such Councilor’s or Officer’s Corporate Status, if such Councilor or Officer acted in good faith and in a manner such Councilor or Officer reasonably believed to be in or not opposed to the best interests of the Society; provided, however, that no indemnification shall be made under this Article XI, Section 2(ii) in respect of any claim, issue or matter as to which such Councilor or Officer shall have been finally adjudged by a court of competent jurisdiction to be liable to the Society, unless, and only to the extent that, the Delaware Court of Chancery or another court in which such Proceeding was brought shall determine upon application that, despite adjudication of liability, but in view of all the circumstances of the case, such Councilor or Officer is fairly and reasonably entitled to indemnification for such Expenses that such court deems proper.


3. Survival of Rights
   The rights of indemnification provided by this Article XI, Section 2 shall continue as to a Councilor or Officer after he or she has ceased to be a Councilor or Officer and shall inure to the benefit of his or her heirs, executors, administrators and personal representatives.


4. Actions by Councilors or Officers
   Notwithstanding the foregoing, the Society shall indemnify any Councilor or Officer seeking indemnification in connection with a Proceeding initiated by such Councilor or Officer only if such Proceeding (including any parts of such Proceeding not initiated by such Councilor or Officer) was authorized in advance by the Council of the Society, unless such Proceeding was brought to enforce such Officer’s or Councilor’s rights to indemnification or, in the case of Councilor, advancement of Expenses under these By-laws in accordance with the provisions set forth herein.

SECTION 3: Advancement of Expenses to Councilors Prior to Final Disposition

1. The Society shall advance all Expenses incurred by or on behalf of any Councilor in connection with any Proceeding in which such Councilor is involved by reason of such Councilor’s Corporate Status within thirty (30) days after the receipt by the Society of a written statement from such Councilor requesting such advance or advances from time to time, whether prior to or after final disposition of such Proceeding. Such statement or statements shall reasonably evidence the Expenses incurred by such Councilor and shall be preceded or accompanied by an undertaking by or on behalf of such Councilor to repay any Expenses so advanced if it shall ultimately be determined that such Councilor is not entitled to be indemnified against such Expenses. Notwithstanding the foregoing, the Society shall advance all Expenses incurred by or on behalf of any Councilor seeking advancement of expenses hereunder in connection with a Proceeding initiated by such Councilor only if such Proceeding (including any parts of such Proceeding not initiated by such Councilor) was (A) authorized by the Council, or (B) brought to enforce such Councilor’s rights to indemnification or advancement of Expenses under these bylaws.


2. If a claim for advancement of Expenses hereunder by a Councilor is not paid in full by the Society within thirty (30) days after receipt by the Society of documentation of Expenses and the required undertaking, such Councilor may at any time thereafter bring suit against the Society to recover the unpaid amount of the claim and if successful in whole or in part, such Councilor shall also be entitled to be paid the expenses of prosecuting such claim. The failure of the Society (including its Council or any committee thereof or independent legal counsel) to make a determination concerning the permissibility of such advancement of Expenses under this Article XI shall not be a defense to an action brought by a Councilor for recovery of the unpaid amount of an advancement claim and shall not create a presumption that such advancement is not permissible. The burden of proving that a Councilor is not entitled to an advancement of expenses shall be on the Society.


3. In any suit brought by the Society to recover an advancement of expenses pursuant to the terms of an undertaking, the Society shall be entitled to recover such expenses upon a final adjudication that the Councilor has not met any applicable standard for indemnification set forth in the DGCL.

SECTION 4: Advancement of Expenses to Officers Prior to Final Disposition

1. The Society may, at the discretion of the Council, advance any or all Expenses incurred by or on behalf of any Officer in connection with any Proceeding in which such person is involved by reason of his or her Corporate Status as an Officer upon the receipt by the Society of a statement or statements from such Officer requesting such advance or advances from time to time, whether prior to or after final disposition of such Proceeding. Such statement or statements shall reasonably evidence the Expenses incurred by such Officer and shall be preceded or accompanied by an undertaking by or on behalf of such person to repay any Expenses so advanced if it shall ultimately be determined that such Officer is not entitled to be indemnified against such Expenses.


2. In any suit brought by the Society to recover an advancement of expenses pursuant to the terms of an undertaking, the Society shall be entitled to recover such expenses upon a final adjudication that the Officer has not met any applicable standard for indemnification set forth in the DGCL.

SECTION 5: Contractual Nature of Rights

1. The provisions of this Article XI shall be deemed to be a contract between the Society and each Councilor and Officer entitled to the benefits hereof at any time while this Article XI is in effect, in consideration of such person’s past or current and any future performance of services for the Society. Neither amendment, repeal or modification of any provision of this Section 5 nor the adoption of any provision of the Certificate of Incorporation inconsistent with this Article XI shall eliminate or reduce any right conferred by this Article XI in respect of any act or omission occurring, or any cause of action or claim that accrues or arises or any state of facts existing, at the time of or before such amendment, repeal, modification or adoption of an inconsistent provision (even in the case of a proceeding based on such a state of facts that is commenced after such time), and all rights to indemnification and advancement of Expenses granted herein or arising out of any act or omission shall vest at the time of the act or omission in question, regardless of when or if any proceeding with respect to such act or omission is commenced. The rights to indemnification and to advancement of expenses provided by, or granted pursuant to, this Article XI shall continue notwithstanding that the person has ceased to be a Councilor or Officer and shall inure to the benefit of the estate, heirs, executors, administrators, legatees and distributees of such person.


2. If a claim for indemnification hereunder by a Councilor or Officer is not paid in full by the Society within sixty (60) days after receipt by the Society of a written claim for indemnification, such Councilor or Officer may at any time thereafter bring suit against the Society to recover the unpaid amount of the claim, and if successful in whole or in part, such Councilor or Officer shall also be entitled to be paid the expenses of prosecuting such claim. The failure of the Society (including its Council or any committee thereof or independent legal counsel) to make a determination concerning the permissibility of such indemnification under this Section 5 shall not be a defense to an action brought by a Councilor or Officer for recovery of the unpaid amount of an indemnification claim and shall not create a presumption that such indemnification is not permissible. The burden of proving that a Councilor or Officer is not entitled to indemnification shall be on the Society.


3. In any suit brought by a Councilor or Officer to enforce a right to indemnification hereunder, it shall be a defense that such Councilor or Officer has not met any applicable standard for indemnification set forth in the DGCL.

SECTION 6:
The rights to indemnification and advancement of Expenses set forth in this Section 5 shall not be exclusive of any other right which any Councilor, Officer, or Non-Officer Employee may have or hereafter acquire under any statute, provision of the Certificate or these By-laws, agreement, vote of stockholders or Disinterested Councilors or otherwise.

SECTION 7:
The Society may maintain insurance, at its expense, to protect itself and any Councilor or Officer against any liability of any character asserted against or incurred by the Society or any such Councilor or Officer, or arising out of any such person’s Corporate Status, whether or not the Society would have the power to indemnify such person against such liability under the DGCL or the provisions of this Article XI.

SECTION 8:
The Society may maintain insurance, at its expense, to protect itself and any Councilor or Officer against any liability of any character asserted against or incurred by the Society or any such Councilor or Officer, or arising out of any such person’s Corporate Status, whether or not the Society would have the power to indemnify such person against such liability under the DGCL or the provisions of this Article XI. The Society’s obligation, if any, to indemnify or provide advancement of Expenses to any person under this Article XI as a result of such person serving, at the request of the Society, as a director, partner, trustee, officer, employee or agent of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise shall be reduced by any amount such person may collect as indemnification or advancement of Expenses from such other corporation, partnership, joint venture, trust, employee benefit plan or enterprise (the “Primary Indemnitor”). Any indemnification or advancement of Expenses under this Article XI owed by the Society as a result of a person serving, at the request of the Society, as a director, partner, trustee, officer, employee or agent of another corporation, partnership, joint venture, trust, employee benefit plan or other enterprise shall only be in excess of, and shall be secondary to, the indemnification or advancement of Expenses available from the applicable Primary Indemnitor(s) and any applicable insurance policies.
