Each person or entity that has a direct connection to e-cbot will request one or more Individual Trade Mnemonics (ITMs) as needed to accommodate the nature and volume of the person’s or entity’s business. A Responsible Person and one or more Backup Responsible Person(s) must be registered with the Exchange for each ITM. The Exchange, at its sole discretion, may limit the number of, or require additional ITMs and Responsible Persons.

A Responsible Person (or in his absence, the Backup Responsible Person) must be reachable via telephone by the Exchange at all times that any of the ITMs assigned to him are in use. A Responsible Person (or in his absence, his Backup Responsible Person) must:

(a)           have the authority, at the Exchange’s request, to modify or withdraw any order submitted under an ITM assigned to him; and

(b)           immediately identify, at the Exchange’s request, the source of any order submitted under an ITM assigned to him. (11/29/07)
