(b) The Adviser shall determine the securities to be purchased or sold by each Fund and will place orders pursuant to its determinations with or through such persons, brokers, or dealers in conformity with the policy with respect to brokerage as set forth in the Trust’s Registration Statement and each Fund’s Prospectus and Statement of Additional Information or as the Trustees may direct from time to time.

2. Sub-advisers and Consultants. The Adviser may from time to time, in its discretion and with the approval of the Board of Trustees, delegate certain of its responsibilities under this Agreement in respect of any Fund to one or more qualified companies (each, a “sub-adviser”), each of which is registered under the Investment Advisers Act of 1940, as amended, provided that the separate costs of employing such sub-advisers and of the sub-advisers themselves are borne by the Adviser or the sub-adviser and not by the Fund in question.   Unless the Board of Trustees specifies otherwise in connection with its approval of any such delegation or unless any agreement pursuant to which such delegation is effected specifies otherwise, (i) the obligation of the Adviser in respect of the activities of any such sub-adviser shall be to provide to the Board of Trustees its recommendation as to the initial selection of the

sub-adviser and as to the periodic renewal of the sub-advisory agreement with the sub-adviser, and to oversee generally the performance by such sub-adviser of its obligations to the Fund in question over time (which oversight may include periodic review of policies and procedures of the sub-adviser but will not include approval of or responsibility for specific investment decisions by the sub-adviser) and to report to the Board of Trustees periodically as to its evaluation of the performance of such sub-adviser and as to the nature and scope of such general oversight, in accordance with the standard of care set out in Section 11 below, and (ii) assuming compliance by the Adviser with its obligations under clause (i), the Adviser shall not be responsible or have any liability for any investment decision or any other act or omission on the part of any sub-adviser, including without limitation any error or mistake of judgment on the part of the sub-adviser or failure by the sub-adviser to comply with any policies, procedures, guidelines, or objectives of any Fund, the Adviser, or the sub-adviser. 

3. Adviser is Independent Contractor. The Adviser shall, for all purposes herein, be deemed to be an independent contractor, and shall, unless otherwise expressly provided and authorized, have no authority to act for or represent the Trust or any Fund in any way, or in any way be deemed an agent for the Trust or any Fund. It is expressly understood and agreed that the services to be rendered by the Adviser to the Trust and each Fund under the provisions of this Agreement are not to be deemed exclusive, and the Adviser shall be free to render similar or different services to others so long as its ability to render the services provided for in this Agreement shall not be impaired thereby.

4. Responsibilities and Personnel of Adviser.

No such name shall be used by the Trust at any time or in any place or for any purposes or under any conditions except as in this section provided.
