With regard to options transactions, Customer understands that some exchange clearing houses have established exercise requirements for the tender of exercise instructions and that options will become worthless in the event that Customer does not deliver instructions by such expiration times. At least two business days prior to the last trading day in the case of long and short positions in options, Customer will give Broker instructions to liquidate, exercise, or allow  the expiration of such options, and will deliver to Broker sufficient funds required in connection with exercise. If such instructions or such funds, are not received by Broker prior to the expiration of the option, Broker may permit an option to expire. Customer also understands that certain exchanges and clearing houses automatically exercise some "in-the-money" options unless instructed otherwise. Customer acknowledges full responsibility for taking action either to exercise or to prevent exercise of an option contract, as the case may be; Broker is not required to take any action with respect to an option, including without limitation any action to exercise a valuable option contract prior to its expiration or to prevent the automatic exercise of an option, except upon Customer's express instructions. Customer further understands that Broker also has established exercise cut-off times, which may be different  from the times established by the contract markets in clearing houses. In the event that timely exercise and assignment instructions are not given, Customer hereby agrees to waive any and all claims for damage or loss Customer might have against Broker arising out of the fact that an option was or was not exercised. Customer understands that Broker randomly assigns exercise notices to Customers, that all short option positions are subject to assignment at any time, including positions established on the same day that exercises are assigned, and that exercise assignment notices are allocated randomly from among all Customers' short option positions which are subject to exercise.
