The Trustee may require the Company, the Partnership, the Participants, any surviving spouses, the Participants’ designated beneficiaries under the Plans or any legal representative of such persons to submit to it any information, data, reports or documents reasonably relevant to and suitable for the purposes of administering the Trust Fund.

The Trustee will forthwith after learning of the identity of the Representative Participant provide notice to all of the Participants as to the identity of the Representative Participant who shall remain in such capacity until the earlier of the date of (a) the termination of the Trust, (b) his or her death, (c) a written certification, statement, letter or affidavit of a physician that the Representative Participant is incapable of managing his or her affairs (or, if later, the date same is received by the Trustee) or (d) the election of his or her replacement by a majority of the Participants in a manner satisfactory to the Trustee. If the position of Representative Participant remains vacant for a period of three (3) months following the appointment of the first (or any subsequent) Representative Participant, the replacement Representative Participant will be the Participant (other than a prior Representative Participant) who the Actuary advises has at such time the greatest present value of benefits payable hereunder.

Any Trustee hereunder may be removed at any time with or without cause by an instrument executed by the Company and the Partnership or, following a Trigger, the Representative Participant and filed with the Trustee. Such resignation or removal, as the case may be, shall take effect ninety (90) days after the instrument of resignation or removal has been filed as provided herein, unless the party with whom such instrument is filed waives such requirement.

4.12 Appointment of Successor Trustee - In case of the resignation or removal of a Trustee or in case a vacancy shall arise for any reason in the trusteeship of the Trust Fund, a successor Trustee, which shall be a duly licensed and qualified trust company, or one or more individuals (provided that no single Participant may be appointed) shall be appointed by an

instrument executed by (i) the Company and the Partnership or (ii) the Representative Participant following a Trigger. Acceptance of the appointment shall be evidenced in writing delivered by such Trustee to the Company and the Partnership or the Representative Participant, as the case may be. Any successor Trustee who accepts such appointment shall have the same powers and duties as those conferred upon the Trustee hereunder and, upon acceptance of such appointment by the successor Trustee, the Trustee shall assign, transfer and pay over to such successor Trustee the funds and properties then constituting the Trust Fund, together with any and all records, books and documents in the Trustee’s possession pertaining to the Trust Fund. Upon such transfer the Trustee shall be discharged from any further liability, obligations and responsibility under the Trust Fund or in connection with the Plans. The Trustee is authorized, however, to reserve such compensation and other expenses reasonably incurred in connection with the administration of the Trust to the date of the resignation or removal of the Trustee and any balance of such reserve remaining after the payment of such compensation and expenses shall be paid over to the successor Trustee.

In the event the Company and the Partnership or the Representative Participant, as the case may be, fails to appoint a successor Trustee within sixty (60) days of the resignation or removal, the Trustee, at the expense of the Trust Fund, shall have the right to seek appointment of a successor Trustee from a court of competent jurisdiction.
