Sara,  Here is the language for "Binding Effect".  Please take a look and let me know if it gets you what you need.  I've attached the Assignment and Assumption agreement for your review.

Binding Effect.    This Agreement shall be binding on and inure to the benefit of the parties and their successors.  In the event that Morgan Stanley (i) merges with another entity, or (ii) ceases to be a FCM or (iii) is required by Applicable Law to transfer its Customer accounts to another FCM, Morgan Stanley shall have the right to transfer or assign this Agreement (and thereby the Account) to any successor entity or to another properly registered futures commission merchant in its sole and absolute discretion and without obtaining the consent of Customer.  Notwithstanding the foregoing, in the event of items (ii) or (iii) immediately above, if permitted by Applicable Law and in the event that Morgan Stanley's position would not be jeopardized thereby, Morgan Stanley will make reasonable efforts under the circumstances to consult Customer for its preference of FCM before assigning this Agreement.  Customer may assign this agreement provided Customer obtains Morgan Stanley's consent by using Morgan Stanley's version of Assignment and Assumption agreement (a copy of which will be provided to Customer) signed by the Customer, the party to which the Agreement is to be assigned, and Morgan Stanley.
