The Settlement Agent shall confirm receipt of such Deposit Amount to the Purchasing Authorized Participant via facsimile or electronic mail message. At its discretion the Trust may accept a Purchase Order for which the corresponding Deposit Amount is received between 5 p.m. and 6 p.m. (New York time). A Purchase Order shall be deemed automatically cancelled if the Settlement Agent has not received the corresponding Deposit Amount in immediately available funds by 6:00 p.m. (New York time) on the Order Date of such Purchase Order.

(d) The Processing Agent (acting in consultation with the Sponsor) shall have the absolute right to reject any Purchase Order including, without limitation, (i) Purchase Orders that the Processing Agent has determined are not in proper form, (ii) Purchase Orders that the Trust has determined would have adverse tax or other consequences to the Trust or to the owners of Shares, (iii) Purchase Orders the acceptance of which would, in the opinion of counsel to the Processing Agent, the Settlement Agent, the Sponsor or the Trust result in a violation of law, (iv) Purchase Orders in respect of which the Settlement Agent has not received in immediately available funds the corresponding Deposit Amount by 5 p.m. (New York time) on the Order Date of such Purchase Order, or (v) Purchase Orders received during any period in which circumstances make transactions in, or settlement or Delivery of, Shares or components of the Portfolio impossible or impractical.

Upon the Settlement Agent’s receipt of the aggregate Deposit Amount corresponding to a Purchase Order as provided in paragraph “(c)” above, the Purchasing Authorized Participant’s offer to purchase the Required Baskets specified in such Purchase Order shall become irrevocable.

(f) By 11:00 a.m. (New York time) on the Issue Date of a Purchase Order, the Trust shall issue the aggregate number of Shares corresponding to the Requested Baskets specified in such Purchase Order and Deliver them by credit to the account at DTC which the Purchasing Authorized Participant shall have identified for such purpose in written instructions to the Settlement Agent, together with immediately available funds in an amount (without, for the avoidance of doubt, any interest on any such amount) equal to the positive difference, if any, between (1) the aggregate Deposit Amount deposited by the Purchasing Authorized Participant in respect of all Requested Baskets specified in such Purchase Order and (2) the sum of (x) the aggregate Order Execution Price of all Requested Baskets specified in such Purchase Order, (y) the Transaction Fee applicable to such Purchase Order, and (z) in the case of a Purchase Order that is a Special Order, any extraordinary losses, costs or expenses incurred in connection with the execution of trades related to such Purchase Order; provided that, if the aggregate Deposit Amount deposited by the Purchasing Authorized Participant in respect of all Requested Baskets specified in such Purchase Order does not suffice to cover the aggregate Order Execution Price of all Requested Baskets specified in such Purchase Order together with the Transaction Fee applicable to such Purchase Order and, in the case of a Purchase Order that is a Special Order, any extraordinary losses, costs or

Sch. 1-5

(ii) any other conditions to the issuance under the Trust Agreement have been satisfied.

(g) In the event that, by 11:00 a.m. (New York time) on the Issue Date of a Purchase Order, a Purchasing Authorized Participant (such Purchasing Authorized Participant, a “Defaulting Authorized Participant”) has failed to deposit with the Settlement Agent the amount described in sub-clause “(f)(i)” above, the Trust may, in consultation with the Sponsor,

(i) cancel such Purchase Order by sending via fax or electronic mail message notice of such cancellation to the Purchasing Authorized Participant, liquidate any trading positions entered into by the Trust in connection with such Purchase Order and transfer to the Defaulting Authorized Participant, in full repayment of the aggregate Deposit Amount deposited by such Defaulting Authorized Participant in respect of all Requested Baskets specified in such Purchase Order, the lower of (1) the proceeds of such liquidation, and (2) the aggregate Deposit Amount deposited by such Defaulting Authorized Participant in respect of all Requested Baskets specified in such Purchase Order (without, for the avoidance of doubt, any interest thereon), in either case net of (x) the Transaction Fee applicable to such Purchase Order and (y) such additional amounts as the Trust, in consultation with the Sponsor, may deem appropriate to compensate the Trust for all damages, costs and expenses (including brokerage fees and commissions) incurred in connection with such Purchase Order; or

(ii) take such other action as the Trust, in consultation with the Sponsor, may deem necessary or appropriate under the circumstances, it being understood and agreed that in making a decision regarding any such other action the Trust and the Sponsor shall be required to take into account the best interests of the Trust and its shareholders only and shall have no duty to ameliorate or mitigate any damages of the Defaulting Authorized Participant.

(h) In all other cases, the Trust shall issue the aggregate number of Requested Shares specified in a Purchase Order and Deliver them by credit to the account at DTC which the Purchasing Authorized Participant shall have identified for such purpose in written instructions to the Settlement Agent on the Business Day on which the conditions set forth in clauses “(f)(i)” and “(f)(ii)” above shall have been met.
