v. quarterly report to the Trustees of the Trust with respect to the implementation of these investment programs; and

i. other subadvisers to a Portfolio;

ii. other subadvisers to a Trust portfolio; and

iii. other subadvisers to a portfolio under common control with a Portfolio.

18. COMPLIANCE

In managing the investments of and determining the composition of the assets of the Portfolios and in performing its other services and obligations hereunder, the Subadviser shall: (i) comply with the investment objectives, policies and restrictions of the Portfolios as set forth in the registration statement of the Trust, as from time to time amended or supplemented; (ii) comply with all policies, guidelines, instructions and procedures approved by the Board or the Adviser with respect to the Portfolios and furnished in writing to the Subadviser; (iii) comply with all applicable requirements of the Investment Advisers Act, the Investment Company Act and the rules and regulations under each thereof, as the same may be amended from time to time; (iv) work collaboratively with the Adviser to cause the Portfolios to comply with the requirements of Subchapter M of the Internal Revenue Code of 1986, as amended (the “Code”), for qualification as a regulated investment company (for so long as the Portfolios seek to qualify as a regulated investment company under the Code); and (v) comply with all other applicable law, rules and regulations.

The Subadviser shall maintain compliance procedures for the Portfolios that the Subadviser reasonably believes are adequate to ensure its and the Portfolios’ compliance with the requirements of this paragraph. For the avoidance of doubt, to the extent a Portfolio comprises only a portion of the total assets of a fund or investment vehicle, the foregoing compliance obligations of the Subadviser shall apply solely with respect to such Portfolio and not to the entire fund or investment vehicle of which such Porfolio is a part.

and resources (including those resources that will permit testing of the Compliance Policies by the Adviser) that the Adviser may reasonably request to enable the Portfolios to comply with Rule 38a-1 under the Investment Company Act. The Subadviser also agrees to provide such other information relating to the Subadviser’s compliance program as may be reasonably requested by the Portfolios, the Portfolios’ Chief Compliance Officer, or his or her authorized representative.

19. CONFLICTS OF INTEREST

It is understood that trustees, officers, agents and shareholders of the Trust are or may be interested in the Subadviser as trustees, officers, partners or otherwise; that employees, agents and partners of the Subadviser are or may be interested in the Trust as trustees, officers, shareholders or otherwise; that the Subadviser may be interested in the Trust; and that the existence of any such dual interest shall not affect the validity hereof or of any transactions hereunder except as otherwise provided in the Agreement and Declaration of Trust of the Trust and the Article of Incorporation of the Subadviser, respectively, or by specific provision of applicable law.
