Notwithstanding my resignation and withdrawal as described above, my resignation and withdrawal shall in no way be deemed to be a waiver or adverse modification of, or to otherwise prevent me (or the parties referred to in clause (f) below) from receiving the benefit of: (a) rights to indemnification by the Company (and if applicable, its affiliates) or any successor thereto, as in effect on the date of my resignation; (b) rights to exculpation by the Company (and if applicable, its affiliates) or any successor thereto, as in effect on the date of my resignation; (c) insurance maintained for the benefit of any current or former member of the Board, as required by the LLC Agreement; (d) any rights to indemnification or exculpation which may be available to me as a matter of applicable law; (e) any and all rights and protections for my benefit granted pursuant to the governance agreements of the Company which otherwise survive my resignation and withdrawal; or (f) any provision in the LLC

Very truly yours,
