However, it is expressly understood and agreed that no party who is an Officer shall have any right of exculpation, indemnification or otherwise under this Section 16 with respect to any action or omission taken or suffered by such party at any time after such party ceases to be an Officer (whether the action resulting in such party ceasing to be an Officer is voluntary, involuntary or otherwise), or in

respect of any controversy relating in any respect to such party’s ceasing to be an Officer, or in respect of any claim or cause of action against the Company (other than in connection with enforcing such party’s rights against the Company under this Section 16), the Member or any affiliate of the Member, or any of the members, partners, stockholders, directors, managers, officers, employees, agents or other representatives of any of the foregoing.
