WHEREAS, the Board of Trustees of the Trust has approved this Amendment to the Subadvisory Agreement and it is not required to be approved by the shareholders of the Portfolios.

NOW, THEREFORE, it is hereby agreed between the parties hereto as follows:

1. Portfolio Transactions. Section 2 to the Subadvisory Agreement is hereby amended to include the following provision:

To the extent permitted by the Portfolios’ current prospectus and statement of additional information, the Subadviser is hereby directed and authorized by the Adviser to (i) negotiate, enter into and execute trading and other agreements on the Trust’s behalf with third parties such as counterparties, clearing houses, clearing members, trading venues and such other intermediaries (including the Trust’s custodian) (each, a “Market Participant”) as the Subadviser deems appropriate including, but not limited to, ISDA Agreements, as supplemented by any schedule, credit support annex (or pledge agreement), and/or confirmations thereto, listed options agreements, as supplemented by any addendum hereto related to exchange-traded derivative transactions agreements, repurchase agreement facilities, master forward securities transaction agreements, standard industry protocol arrangements (including those published by ISDA) and any such other agreements or arrangements as may be necessary or desirable to effect the investments and transactions contemplated by the Portfolios’ investment guidelines and (ii) effect transactions in derivatives with such counterparties, in such a manner and on such trading venues as the Subadviser considers appropriate. Where applicable, all such transactions shall be effected in accordance with the rules and regulations (if any) of the relevant trading venue and the Subadviser may take all such steps as the Subadviser considers reasonable or as may be required or permitted by such rules and regulations and/or by appropriate market practice. Upon the reasonable request of the Adviser, the Subadviser will provide copies of any such agreements or other documents to the Adviser.

The Subadviser also is authorized on a continuing basis to maintain at Markit Group Limited (or such other intermediaries as it deems reasonable) for delivery to relevant Market Participants, information (including confidential information) relating to the Portfolios and all such constituent and other documentation as may be required by such Market Participants in connection with the Subadviser’s use of derivatives and/or in order to effect, clear or otherwise manage transactions in derivatives on behalf of the Portfolios.
