SCHEDULE B

AGENCY SERVICES AGREEMENT

INDEX RECEIPT AGENT SERVICES

AND RELATED CUSTODY SERVICES FOR ETF SERIES

Following are the Index Receipt Agent services that shall be provided by J.P. Morgan for the Trust in respect of each Fund and their respective ETF Series. J.P. Morgan shall perform these services as Index Receipt Agent in conjunction with the custody services that are currently provided by J.P. Morgan, as Custodian, to each Fund under the terms of the Custody Agreement. J.P. Morgan shall be entitled to all the protective provisions in the Custody Agreement in respect of its duties and its performance as Index Receipt Agent and Custodian for the settlement of creations and redemptions of Creation Units of each ETF Series. If there are any inconsistencies between the terms of the Custody Agreement and the terms herein with respect to processing, clearance and the settlement of creation and redemption orders for ETF Shares of each ETF Series the terms herein shall govern. Unless otherwise defined in this Schedule B, defined terms will have the same meaning as set forth in Section I of this Agreement.

A. Index Receipt Agent Services.

    1. J.P. Morgan, with the assistance of the Trust, shall make application to NSCC to be the Index Receipt Agent on behalf of the Trust and each ETF Series for the processing, clearance and the settlement of creation and redemption orders for ETF Shares of each ETF Series and Creation Deposits through the facilities of NSCC and DTC. The forgoing shall only applicable to US domestic ETFs that maintain DTC eligible baskets of securities. US domestic ETFs that maintain non-DTC eligible baskets of securities and US domiciled global ETFs will be processed via proprietary ETF servicing modules. However, J.P. Morgan shall continue to deliver the Portfolio Composition Files to the NSCC for further dissemination to market participants.

    2. The Distributor, on behalf of the Trust, shall enter into an Authorized Participant Agreement with each Authorized Participant, which shall be delivered to the J.P. Morgan and which J.P. Morgan, in its capacity as Index Receipt Agent, shall acknowledge.

    3. In connection with the procedures that may be established from time to time between J.P. Morgan and the Trust on behalf of each ETF Series for the processing, clearance and settlement of the creation and redemption of Creation Units through the Clearing Process, J.P. Morgan shall:

4

(a)     (i) receive from the Investment Adviser daily, a computer generated file that is in form and substance acceptable to NSCC containing a list of the Deposit Securities (if applicable) for each ETF Series, (ii) receive from the Order Taker daily, a computer generated file that is in form and substance acceptable to NSCC containing the Balancing Amount and the Transaction Fee for each ETF Series and (iii) transmit both files (referenced in subparagraphs (i) and (ii) herein) as received to NSCC;

(b)     receive from the Order Taker on each trade date a computer generated file that is in form and substance acceptable to NSCC and that contains creation orders from Authorized Participants that have been accepted by the Distributor on behalf of the Trust and each ETF Series, for the creation of Creation Units against delivery of Deposit Securities and a Cash Component; transmit the file of creation orders as received from the Order Taker to NSCC; receive back from NSCC the file of creation orders enhanced with NSCC generated prices for the Deposit Securities contained in the file and deliver the enhanced file to Custodian for settlement; and, pursuant to such creation orders, instruct the Transfer Agent to create the appropriate number of ETF Shares of the applicable ETF Series for deposit to the Custodian’s DTC Participant Account;

(c)     receive from the Order Taker on each trade date a computer generated file that is in form and substance acceptable to NSCC and that contains redemption orders from Authorized Participants that have been accepted by the Distributor on behalf of the Trust for each ETF Series; transmit the file of redemption orders as received from the Order Taker to NSCC; receive back from NSCC the file of redemption orders enhanced with NSCC generated prices for the Redemption Securities contained in the file and deliver the enhanced file to Custodian for settlement; and, pursuant to such redemption orders, instruct the Transfer Agent to redeem the appropriate number of ETF Shares of the applicable ETF Series in Creation Units and reduce the account of the Shareholder accordingly; and

(d)     at the appropriate times, cause to be paid over to Authorized Participants Balancing Amounts on the creation or redemption of Creation Units, as instructed by the Order Taker or the Trust on behalf of each ETF Series.

    4. The Trust understands and agrees that all risk associated with the processing, clearance and settlement of the creation and redemption of ETF Shares, Deposit Securities and Redemption Securities and cash through the Clearing Process shall be that of the Trust and each ETF Series irrespective of whether in effecting such creations and redemptions for the Trust on behalf of each ETF Series through the Clearing Process, J.P. Morgan, as a member of NSCC, is acting as principal or as agent; and, in respect hereof, the Trust and each ETF Series, shall be bound by all the rules and procedures of NSCC and DTC as though it were the member or participant of such clearing and settlement systems.

5

B. Outside the Clearing Process.

    1. The following transactions shall be handled Outside the Clearing Process:

(i) any creation or redemption of Creation Units that the Trust, its Distributor or another authorized agent shall instruct J.P. Morgan to settle Outside the Clearing Process; J.P. Morgan will set up ETFs for processing, clearing and settlement within the Clearing Process or Outside of the Clearing Process. This set up is not subject to change on an ad hoc basis; and

(ii) any security create that is part of a Creation Deposit or redemption of Creation Units and that according to NSCC rules is deemed to be ineligible for the Clearing Process, including securities that are not eligible to be settled through DTC.

    2. All such transactions shall be effected by J.P. Morgan on a delivery-versus-payment and receive-versus-payment basis through DTC and according to DTC’s rules, and the Trust or the ETF Series shall provide to J.P. Morgan the information and terms that are necessary to settle each transaction, including the cash value of each security settlement, unless the Trust’s or the ETF Series’ Instruction is that delivery is to be made free of payment; provided, however, that any security that is not DTC eligible shall be settled as a window delivery pursuant to street practice. All such transactions shall be effected by J.P. Morgan as Custodian and subject to the terms of the Custody Agreement. US fixed income securities that are not DTC eligible will be settled free of payment via the Fed or similar US clearing structure. Foreign equity and fixed income securities will be settled locally free of payment.

    3. The Trust recognizes that fails to receive (including partial fails) may occur from time to time with respect to one or more of the security creates in a basket of Deposit Securities settled outside the Clearing Process, including but not exclusive to non-DTC eligible domestic ETFs, US-domiciled global fixed income ETFs and US-domiciled global equity ETFs. The Trust acknowledges and agrees that, whenever a fail to receive shall occur on a settlement date, J.P. Morgan will make available to the Trust a report that details such fails to receive and their value. The Trust will in turn instruct the necessary parties about the required collateral that will be delivered to J.P. Morgan by an Authorized Participant. J.P.Morgan will maintain a separate account that will be used for receipt of such collateral.

C. Settlement of Cash Component.

Any Cash Component to a particular transaction shall be handled over the funds transfer wire (Fedwire) or as part of J.P. Morgan’s overall daily net cash settlement at DTC.

D. Creation Deposits through the Clearing Process: Allocation of Fails; Posting of Accounts.

6

    1. The Trust recognizes that fails to receive (including partial fails) may occur from time to time with respect to one or more of the security creates in a basket of Deposit Securities settled through the Clearing Process. The Trust acknowledges and agrees that, whenever a fail to receive shall occur on a settlement date, J.P. Morgan shall book to a single control account maintained for all funds for which J.P. Morgan provides Index Receipt Agent services (the “Control Account”), the quantity of the security that it failed to receive (each such fail a “short receive position”) and the cash value of that short position that it receives from NSCC (and that NSCC, pursuant to its rules, marks to market daily) pending settlement. J.P. Morgan shall not post to any ETF Series account any cash that it receives from NSCC on a short receive position pending settlement.

J.P. Morgan shall make available to the Trust a daily listing of all short receive positions that are in the Control Account and that relate to any ETF Series. J.P. Morgan will allocate daily, on a pro-rata or other basis deemed by it to be fair and equitable, short receive positions in the same security that is common to the securities accounts of such ETF Series and to the securities accounts of such other funds for which J.P. Morgan is acting as Index Receipt Agent. The Trust agrees that any such allocation shall be conclusive on the Trust and the affected ETF Series. When the Deposit Securities that are subject of the short receive positions are received by J.P. Morgan, they will be credited by J.P. Morgan on a FIFO basis to the custody accounts of the applicable funds. J.P. Morgan shall not process a securities transaction in a security having a short receive position in the Control Account to the extent the Trust does not have a sufficient quantity of that security in its ETF Series accounts with J.P. Morgan to settle the transaction. Custodian shall post Deposit Securities to the applicable ETF Series custody accounts on a contractual settlement basis pursuant to the terms of the Custody Agreement.

    2. Should a short receive position in a security remain in the Control Account for two (2) or more NSCC business days, the Trust may elect to instruct J.P. Morgan to exercise NSCC’s buy-in rules with respect to that short position. If an ETF Series needs to sell a short security in its account, the Trust may request that J.P. Morgan exercise a buy-in of the short security under applicable NSCC rules.

E. Redemptions through the Clearing Process: Delivery Fails; Posting of Cash.

    1. The Trust recognizes that on the redemption of Creation Units of an ETF Series through the Clearing Process J.P. Morgan, on behalf of the applicable ETF Series, is obligated to deliver to NSCC on the settlement date the required type and amount of Redemption Securities to redeem the Creation Units of the applicable ETF Series. It shall be the responsibility of the Trust and each ETF Series to maintain in the custody account the required type and amount of Redemption Securities for the redemption of Creation Units of each ETF Series. Should the custody account of an ETF Series for any reason (for example, through the Trust’s participation in a securities lending program on behalf of the ETF Series) have a short position in respect of any of the securities creates comprising the basket of Redemption Securities (a “short delivery position”) with the

7

result that, on settlement date, J.P. Morgan is unable to deliver a sufficient quantity of the Redemption Securities to NSCC, the Trust acknowledges that J.P. Morgan shall be obligated under NSCC’s rules to fund the short delivery position with cash pending delivery of the quantity of securities needed to cover the short delivery position. J.P. Morgan shall be entitled to charge to the account of the applicable ETF Series the amount of cash needed to cover the short delivery position. In the event that J.P. Morgan advances its own funds to cover an ETF Series short delivery position, J.P. Morgan, in its discretion, may charge the applicable EFT Series interest on the amount of the advance at the rate that J.P. Morgan charges for advances of a similar nature to similar customers of J.P. Morgan, unless J.P. Morgan and the Trust have mutually agreed in writing upon another rate.

    2. In the event that J.P. Morgan shall have advanced its own funds to cover a short delivery position at NSCC for an ETF Series, J.P. Morgan shall have, to the extent of the amount of the advance, a security interest in the securities that remain in the ETF Series custody account and J.P. Morgan shall have all the rights and remedies of a secured party under the New York Uniform Commercial Code. Nothing herein or in the Custody Agreement shall be construed to mandate that J.P. Morgan, acting as Index Receipt Agent for the Trust and each ETF Series, effect redemptions of Creation Units where J.P. Morgan, acting in good faith, believes that it may not be repaid an advance by the Trust or the ETF Series or otherwise not receive from the ETF Series delivery of the Redemption Securities that are the subject of a short delivery position.

F Establish Procedures.

The Trust and J.P. Morgan, from time to time, may establish written procedures for the processing and settlement and related activities effected for ETF Shares of each ETF Series through the Clearing Process and Outside the Clearing Process.
