Regular statements of account provide simplified recordkeeping. The Agent may establish procedures for communications with participants relating to the Plan which may be electronic, by telephone or in writing, and may establish such other procedures for the administration of the Plan as may be appropriate. If the Agent is terminated or ceases to act as Agent under the Plan, its successor will be designated by the Company and participants will be promptly notified of the change.
