                                amount of all Exchange Contracts on which
                                delivery is to be effected and settlement
                                allowed in any two business day period to be

                                nor shall Borrower permit the total gross
                                amount of all Exchange Contracts to which
                                Borrower is a party, outstanding at any one
                                time, to exceed the Contract Limit.

                                Notwithstanding the above, however, the amount
                                which may be settled in any two (2) business

                                circumstances (the "Discretionary Settlement
                                Circumstances"):

                                   (i) if there is sufficient availability under
                                   the Credit Limit regarding the Revolving

                                Provided that it is expressly understood that
                                Silicon's willingness to adopt the

                                Facility, or to debit Borrower's account for
                                the amount settled.

                                or any transactions relating thereto or

                                is a base rate upon which other rates charged
                                by Silicon are based, and it is not necessarily
                                the best rate available at Silicon.  The
                                interest rate applicable to the Obligations
                                shall change on each date there is a change in
