administrative or investigative, that relate to the operations of the Company as set forth in these Regulations in which a Member, Officer or employee may be involved, or is threatened to be involved, as a party or otherwise, REGARDLESS OF WHETHER ARISING FROM ANY ACT OR OMISSION WHICH CONSTITUTED THE SOLE, PARTIAL OR CONCURRENT NEGLIGENCE (WHETHER ACTIVE OR PASSIVE) OF A MEMBER, OFFICER OR EMPLOYEE, unless it is established that: (1) the act or omission of such Member, Officer or employee was material to the matter giving rise to the proceeding and either was committed in bad faith or was the result of active and deliberate dishonesty; (2) the Member, Officer or employee actually received an improper personal benefit in money, property or services; or (3) in the case of any criminal proceeding, the Member, Officer or employee had reasonable cause to believe that the act or omission was unlawful. The termination of any proceeding by judgment, order or settlement does not create a presumption that the Member, Officer or employee did not meet the requisite standard of conduct set forth in this Section 10. The termination of any proceeding by conviction or upon a plea of nolo contendere or its equivalent, or an entry of an order of probation prior to judgment, creates a rebuttable presumption that the Member, Officer or employee acted in a manner contrary to that specified in this Section 10. Any indemnification pursuant to this Section 10 shall be made only out of the assets of the Company, including insurance proceeds, if any, and no Member shall have any personal liability on account thereof.
