(b) Upon reasonable notice to Customer, DBSI may limit the size and number of open Contracts (net or gross) that Customer may execute, clear and/or carry with it. DBSI’s position limits may be more restrictive than the limits imposed under Relevant Law. The Trust, on behalf of the Customer, agrees that it will not place any order, which, if filled, would cause Customer to exceed these limits. Further, DBSI may require Customer to liquidate any open positions carried in Customer’s Account, and may refuse to accept any order of Customer establishing a new position in order to comply with such limits.

(c) DBSI may in its sole discretion select executing brokers, clearing and non-clearing brokers and floor brokers, whether or not affiliated or related to DBSI, to execute, clear or carry Customer’s transactions hereunder.

(b) The Trust, on behalf of the Customer, agrees that DBSI, its officers, directors, stockholders, representatives or associated persons may have certain conflicts of interest in connection with the services contemplated hereby, including but not limited to conflicts arising from positions established for their
