          WHEREAS, Trust desires to retain Advisor to render investment advisory and management services to the Funds, in the manner and on the terms and conditions set forth in this Agreement;

          WHEREAS, Advisor is willing to provide investment advisory and management services to the Funds in the manner and on the terms and conditions set forth in this Agreement;

          NOW, THEREFORE, in consideration of the premises and the mutual covenants herein contained, Trust and Advisor hereby agree as follows:

          1.           Appointment.

          Trust hereby appoints Advisor to act as the Funds’ investment adviser and manager for the periods and on the terms set forth herein. Advisor hereby accepts the appointment as investment adviser and manager, and agrees, subject to the supervision of the board of trustees of Trust (the “Board”), to furnish the services and assume the obligations set forth in this Agreement for the compensation provided for herein.

          2.           Generally.

                       (a)           As the Funds’ investment adviser and manager, Advisor shall be subject to: (1) the restrictions of the Declaration of Trust of Trust, as amended from time to time; (2) the provisions of the 1940 Act and the Advisers Act; (3) the statements relating to the Funds’ investment objectives, investment policies and investment restrictions as set forth in the currently effective (and as amended from time to time) registration statement of Trust under the Securities Act of 1933, as amended (the “1933 Act”), and the 1940 Act; (4) any applicable provisions of

the Internal Revenue Code of 1986, as amended (the “Code”); and such other limitations as Trust shall communicate to Advisor in writing.

                       (b)           Advisor shall, for all purposes herein, be deemed to be an independent contractor and shall, unless otherwise expressly provided or authorized, have no authority to act for or represent Trust or a Fund in any way or otherwise be deemed an agent of Trust or a Fund.

                       (c)           Advisor shall, for purposes of this Agreement, have and exercise full investment discretion and authority to act as agent for the Funds in buying, selling or otherwise disposing of or managing the Funds’ investments, directly or through sub-advisers, subject to supervision by the Board.

          3.           Investment Advisory Services

                       (a)           Advisor shall provide the Funds with such investment research, advice and supervision as Advisor may from time to time consider necessary or appropriate for the proper management of the assets of each Fund, shall furnish continuously an investment program for each Fund, shall determine which securities or other investments shall be purchased, sold or exchanged and what portions of each Fund shall be held in the various securities or other investments or cash, and shall take such steps as are necessary to implement an overall investment plan for each Fund, including providing or obtaining such services as may be necessary in managing, acquiring or disposing of securities, cash or other investments.

                       (b)           Trust has furnished or will furnish Advisor with copies of Trust’s registration statement and Declaration of Trust, as currently in effect and agrees during the continuance of this Agreement to furnish Advisor with copies of any amendments or supplements thereto before or at the time the amendments or supplements become effective. Advisor will be entitled to rely on all documents furnished by Trust.

                       (c)           Advisor shall take, on behalf of each Fund, all actions that it deems necessary to implement the investment policies of such Fund, and in particular, to place all orders for the purchase or sale of portfolio investments for the account of each Fund with brokers, dealers, futures commission merchants or banks selected by Advisor. Advisor also is authorized as the agent of Trust to give instructions to any service provider serving as custodian of the Funds as to deliveries of securities and payments of cash for the account of each Fund. In selecting brokers or dealers and placing purchase and sale orders with respect to assets of a Fund, Advisor is directed at all times to seek to obtain best execution within the policy guidelines determined by the Board and set forth in the current registration statement. Subject to this requirement and the provisions of the 1940 Act, the Advisers Act, the Securities Exchange Act of 1934, as amended (the “1934 Act”), and other applicable provisions of law, Advisor may select brokers or dealers that are affiliated with Advisor or Trust.

                       (d)           Consistent with Advisor’s obligation to provide best execution, Advisor may also take into consideration research and statistical information, wire, quotation and other services provided by brokers and dealers to Advisor. Advisor is also authorized to effect individual securities transactions at commission rates in excess of the minimum commission

rates available, if Advisor determines in good faith that such amount of commission is reasonable in relation to the value of the brokerage, research and other services provided by such broker or dealer, viewed in terms of either that particular transaction or Advisor’s overall responsibilities with respect to each Fund. The policies with respect to brokerage allocation, determined from time to time by the Board are those disclosed in the currently effective registration statement. Advisor will periodically evaluate the statistical data, research and other investment services provided to it by brokers and dealers. Such services may be used by Advisor in connection with the performance of its obligations under this Agreement or in connection with other advisory or investment operations including using such information in managing its own accounts.

                       (e)           As part of carrying out its obligations to manage the investment and reinvestment of the assets of each Fund consistent with the requirements under the 1940 Act, Advisor shall:

                       (b)         Nothing in this Agreement shall be deemed to diminish the obligations of any agent of Trust or other person not a party to this Agreement that is obligated to provide services to the Funds.

                       (c)           In the event of termination of this Agreement, all compensation due through the date of termination will be calculated on a pro-rated basis through the date of termination and paid within fifteen business days of the date of termination.

                       (d)           During any period when the determination of net asset value is suspended, the net asset value of a Fund as of the last business day prior to such suspension shall for this purpose be deemed to be the net asset value at the close of each succeeding business day until it is again determined.

          7.           Limitation of Liability.

                       (a)           Advisor shall not be liable for any error of judgment or mistake of law or for any loss arising out of any investment or for any act or omission in the management of Trust or any Fund, except (i) for willful misfeasance, bad faith or negligence in the performance of its duties or by reason of reckless disregard of its obligations and duties hereunder, and (ii) to the extent specified in Section 36(b) of the 1940 Act concerning loss resulting from a breach of fiduciary duty with respect to the receipt of compensation.

                       (b)           Advisor is hereby expressly put on notice of the limitation of shareholder liability as set forth in the Declaration of Trust and agrees that obligations assumed by Trust or each Fund pursuant to this Agreement shall be limited in all cases to Trust or that Fund and its respective assets.
