and Section 817(h) of the IRC and that the Sub-Adviser has no separate and independent responsibility to test the Fund for such compliance. In connection with such compliance tests, the Adviser shall promptly inform the Sub-Adviser if the Funds are out of compliance with the diversification requirements under Subchapter M. If the Adviser notifies the Sub-Adviser that the Funds are not in compliance with such requirements noted above, the Sub-Adviser will take prompt action to bring the Funds back into compliance within the time permitted under the Code.

The Adviser agrees that the Sub-Adviser shall not be liable for any failure to recommend the purchase or sale of any security on behalf of any Fund on the basis of any information which might, in the Sub-Adviser’s reasonable opinion, constitute a violation of any federal or state laws, rules or regulations.

will provide reasonable assistance to the Adviser or the Trust’s fund accountant or the Trust’s custodian, as the case may be, in determining the value of any portfolio security. In addition, the Sub-Adviser or its agent shall provide the Trust’s custodian on each business day with information relating to all transactions concerning each Fund’s assets under Sub-Adviser’s supervision, and shall provide Adviser with such information upon the reasonable request of the Adviser;

Custody of Assets. Title to all investments shall be held in the name of the Funds, provided that for convenience in buying, selling and exchanging securities (stocks, bonds, commercial paper, etc.), title to such securities may be held in the name of the Trust’s custodian bank, or its nominee. All cash and the indicia of ownership of all other investments shall be held by the Trust’s custodian bank. Sub-Adviser shall not act as custodian of the assets held in the Funds and shall at no time have the right to physically possess the assets of the Funds or have the assets registered in its own name or the name of its nominee, nor shall Sub-Adviser in any manner acquire or become possessed of any income, whether in kind or cash, or proceeds, whether in kind or cash, distributable by reason of selling, holding or controlling such assets of the Funds. In accordance with the preceding sentence, Sub-Adviser shall have no responsibility with respect to the collection of income, physical acquisition or the safekeeping of the assets of the Funds. All such duties of collection, physical acquisition and safekeeping shall be the sole obligation of the custodian. The Sub-Adviser shall have no liability for the acts or omissions of the authorized custodian(s), unless such act or omission is required by and taken in reliance upon instructions given to the authorized custodian(s) by a representative of the Sub-Adviser pursuant to the authorized signatory lists provided to the Adviser by the Sub-Adviser or as a result the Sub-Adviser’s willful misfeasance, bad faith, gross negligence, fraud, reckless disregard, or willful misconduct in connection with any actions that the Sub-Adviser has taken or should have taken with respect to the authorized custodian. Sub-Adviser has not assisted in the selection of the Funds’ custodian.

The Trust or the Adviser shall notify the Sub-Adviser of the identities of its custodian bank and the custody arrangements therewith with respect to the Funds and shall give the Sub-Adviser written notice of any changes in such custodian bank or custody arrangements. The Sub-Adviser shall on each business day provide the Adviser and the Trust’s custodian such information as the Adviser and the Trust’s custodian may reasonably request in good faith relating to all transactions concerning the Funds. The Trust shall instruct its custodian bank to (a) carry out all investment instructions as may be directed by the Sub-Adviser with respect to the Funds (which instructions may be orally given if confirmed in writing and in accordance with the respective custody agreement); and (b) provide the Sub-Adviser with all operational information reasonable necessary for the Sub-Adviser to trade the Sub-Adviser assets on behalf of the Fund.

Brokerage. The Sub-Adviser is responsible for decisions to buy and sell securities for each Fund, broker-dealer selection, and negotiation of brokerage commission rates. Sub-Adviser shall have the express authority to negotiate, open, continue and terminate brokerage accounts and other brokerage arrangements with respect to all portfolio transactions entered into by Sub-Adviser on behalf of the Funds. Adviser shall provide such assistance to the Sub-Adviser in setting up and maintaining brokerage accounts and other accounts as the Sub-Adviser shall reasonably request to allow for the purchase or sale of various forms of securities and instruments pursuant to this Agreement. Sub-Adviser will provide copies of all such agreements to the Adviser upon the Adviser’s reasonable request. It is the Sub-Adviser’s general policy in selecting a broker to effect a particular transaction to seek to obtain “best execution,” which means prompt and efficient execution of the transaction at the best obtainable price under the circumstances and taking into account all relevant factors and considerations of the specific transaction, with payment of commissions which are reasonable in relation to the value of the brokerage services provided by the broker. Consistent with this policy, and when selecting a broker the Sub-Adviser will take relevant factors into consideration, including (as applicable), but not limited to: the available prices; the reliability, integrity and financial condition of the broker-dealer; the size of and difficulty in executing the order; and the value of the expected contribution of the broker-dealer to the investment performance of the applicable Fund on a continuing basis. The foregoing list is not exhaustive and collectively, including with items not listed, are the “Portfolio Execution Services”. The price to the Fund in any transaction may be less favorable than that available from another broker-dealer if the difference is reasonably justified by other aspects of the Portfolio Execution Services offered under the circumstances of any particular transaction. Subject to such policies and procedures as the Board of Trustees may determine, the Sub-Adviser shall have discretion to effect investment transactions for each Fund through broker-dealers (including, to the extent permissible under applicable law, broker-dealer affiliates) who provide brokerage and/or research services, as such services are defined in Section 28(e) of the Securities Exchange Act of 1934, as amended (the “1934 Act”), and as interpreted by the SEC, and to cause such Fund to pay any such broker-dealers an amount of commission for effecting a portfolio investment transaction in excess of the amount of commission another broker-dealer would have charged for effecting that transaction, if the Sub-Adviser determines in good faith that such amount of commission is reasonable in relation to the value of the brokerage or research services provided by such broker-dealer, viewed in terms of either that particular investment transaction or the Sub-Adviser’s overall responsibilities with respect to such Fund and other accounts to which the Sub-Adviser exercises investment discretion (as such term is defined in Section 3(a)(35) of the 1934 Act). Allocation of orders placed by the Sub-Adviser on behalf of a Fund to such broker-dealers shall be in such amounts and proportions as the Sub-Adviser shall determine in good faith in conformity with its responsibilities under applicable laws, rules and regulations. The Sub-Adviser will submit reports on such allocations to the Adviser as reasonably requested by the Adviser, in such form as may be mutually agreed to by the parties hereto, indicating the broker-dealers to whom such allocations have been made and the basis therefore. The Sub-Adviser shall not be liable for any act or omission of any brokerage firm or firms or counterparties designated by the Adviser or chosen by the Sub-Adviser with reasonable care except by reason of the Sub-Adviser’s willful misfeasance, bad faith, gross negligence, fraud, reckless disregard or willful misconduct in connection with selecting such brokerage firms or firms or counterparties.

Expenses. The Sub-Adviser shall bear all expenses of its operation incurred by it in connection with the performance of its services under this Agreement. The Sub-Adviser shall not be responsible for the Trust’s, the Fund’s or Adviser’s expenses, which shall include, but not be limited to, the cost of securities, commodities and other investments (including brokerage commissions and other transaction charges, if any) purchased for the Fund and any losses incurred in connection therewith, expenses of holding or carrying assets of the Fund managed by the Sub-Adviser, including, without limitation, expenses of dividends on stock borrowed to cover a short sale and interest, fees or other charges incurred in connection with leverage and related borrowings with respect to the assets of the Fund managed by the Sub-Adviser, organizational and offering expenses (which include, but are not limited to, out-of-pocket expenses, but not overhead or employee costs of the Sub-Adviser); expenses for legal, accounting and auditing services; taxes and governmental fees; dues and expenses incurred in connection with membership in investment company organizations; costs of printing and distributing shareholder reports, proxy materials other than those related to a change in the control of the Sub-Adviser or its parent company, prospectuses, stock certificates and distribution of dividends; charges of the Fund’s custodians and sub-custodians, administrators and sub-administrators, registrars, transfer agents, dividend disbursing agents and dividend reinvestment plan agents; payment for portfolio pricing services to a pricing agent, if any; registration and filing fees of the SEC; expenses of registering or qualifying securities of the Fund for sale in the various states; freight and other charges in connection with the shipment of the Fund’s portfolio securities; fees and expenses of non-interested Trustees; salaries of shareholder relations personnel; costs of shareholders meetings; insurance; interest; and brokerage costs. The Trust or the Adviser, as the case may be, shall reimburse the Sub-Adviser for any expenses of the Fund or the Adviser as may be reasonably incurred by such Sub-Adviser on behalf of the Fund or the Adviser. The Sub-Adviser shall notify and receive approval from the Trust or the Adviser (as applicable) prior to incurring any such expenses. The Sub-Adviser shall keep and supply to the Trust and the Adviser reasonable records of all such expenses.

Each of the Fund or the Adviser will bear all expenses to be incurred in its respective operation, including, but not limited to, investment advisory fees, and administration fees; fees for necessary professional and brokerage services; transaction fees and expenses; costs relating to local administration of securities; and fees for any pricing services. All other expenses not specifically assumed by the Sub-Adviser hereunder or by the Adviser under the Management Agreement are borne by the applicable Fund or the Trust.

Books and Records. In compliance with the requirements of Rule 31a-3 under the 1940 Act, the Sub-Adviser hereby agrees that all records which it maintains for the Trust are the property of the Trust and further agrees to surrender promptly to the Trust any of such records upon the Trust's request, copies of which may be retained by the Sub-Adviser. Sub-Adviser further agrees to preserve for the periods prescribed by Rule 31a-2 under the 1940 Act the records required to be maintained by Rule 31a-1 under the 1940 Act related to each Fund’s portfolio transactions. The Adviser shall maintain all books and records not related to the Fund’s portfolio transactions. The Fund’s Records shall be available to the Adviser or the Trust at any time upon reasonable request during normal business

Page 9 of 17

.	hours and shall be available for telecopying promptly to the Adviser during any day that the Fund is open for business as set forth in the Prospectus.

Compensation. For the services provided and the expenses assumed pursuant to this Agreement, the Adviser will pay the Sub-Adviser, and the Sub-Adviser agrees to accept as full compensation therefore, a sub-advisory fee accrued daily and payable monthly on the average daily net assets in the Funds in accordance with Schedule B hereto.

The method of determining the net asset value for purposes hereof shall be the same as the method of determining net asset value for purposes of establishing the offering and redemption price of the shares of the Trust as described in the Fund’s Prospectus and/or Statement of Additional Information. If this Agreement shall be effective for only a portion of a month with respect to the Fund, the aforesaid fee shall be prorated for the portion of such month during which this Agreement is in effect for the Fund.

Services to Others. Adviser understands, and has advised the Board of Trustees, that Sub-Adviser now acts, or may in the future act, as an investment adviser to fiduciary and other managed accounts, and as investment adviser or sub-investment adviser to other investment companies or accounts. Adviser has no objection to Sub-Adviser acting in such capacities, provided that whenever the Fund and one or more other investment advisory clients of Sub-Adviser have available funds for investment, investments suitable and appropriate for each will be allocated in a manner reasonably believed by Sub-Adviser to be fair and equitable to each. Sub-Adviser may group orders for a Fund with orders for other funds and accounts to obtain the efficiencies that may be available on larger transactions when it reasonably determines that investment decisions are appropriate for each participating account. Sub-Adviser cannot assure that such policy will not adversely affect the price paid or received by a Fund. Adviser recognizes, and has advised the Board of Trustees, that in some cases this procedure may adversely affect the size and the opportunities of the position that the participating Fund may obtain in a particular security. In addition, Adviser understands, and has advised the Board of Trustees, that the persons employed by Sub-Adviser to assist in Sub-Adviser's duties under this Agreement will not devote their full time to such service, and nothing contained in this Agreement will be deemed to limit or restrict the right of Sub-Adviser or any of its affiliates to engage in and devote time and attention to other businesses or to render services of whatever kind or nature.

Notwithstanding any other provision to the contrary, the Sub-Adviser shall have no obligation to perform the following services or to have employees of the Sub-Adviser perform the following roles, as applicable: a) shareholder services or support functions, such as responding to shareholders’ questions about a Fund or its investments or strategies; b) providing employees of the Sub-Adviser to serve as officers of a Fund; or c) providing employees of the Sub-Adviser to serve as the Fund’s Chief Compliance Officer and associated staff. The foregoing list is not exhaustive; the Sub-Adviser’s sole responsibilities under this Agreement are to provide investment management services to the Funds and any additional related responsibilities as may be mutually agreed to by the parties.

10.	Limitation of Liability.

Page 10 of 17

Sub-Adviser, its officers, directors, employees, agents or affiliates will not be subject to any liability to the Adviser or the Funds or their directors, officers, employees, agents or affiliates for any act, omission, error of judgment or mistake of law or for any loss suffered by the Funds, any shareholder of the Funds or the Adviser either in connection with the performance of Sub-Adviser's duties under this Agreement or its failure to perform due to events beyond the reasonable control of the Sub-Adviser or its agents, except for a loss resulting from Sub-Adviser's willful misfeasance, or gross negligence in the performance of its duties or by reason of its reckless disregard of its obligations and duties under this Agreement.

The Sub-Adviser makes no representation or warranty, express or implied, that any level of performance or investment results will be achieved by the Funds or that a Fund will perform comparably with any standard or index, including other clients of the Sub-Adviser, whether public or private.

In any action in which the Sub-Adviser or any of its controlling persons, or any shareholders, partners, directors, officers and/or employees of any of the foregoing, are parties, the Adviser agrees to indemnify and hold harmless the foregoing persons against any losses to which such persons may become subject, insofar as such losses arise out of or are based upon the Adviser’s willful misfeasance, bad faith, gross negligence, fraud, reckless disregard or willful misconduct in performing its responsibilities hereunder, including without limitation the operation of a Fund, the contents of the Funds’ Prospectus, or the wrongful conduct of persons with respect to the sale of interests in a Fund, provided that the loss, claim, settlement, damage, charge, liability, cost or expense did not relate to, was not based upon, or did not arise out of an act or omission of the Sub-Adviser or any of its controlling persons, or any shareholders, partners, directors, officers and/or employees constituting reckless disregard, willful misfeasance, bad faith, gross negligence, fraud or willful misconduct.

e)	Without limiting the generality of the foregoing, neither the Adviser nor the Sub-Adviser will be liable for any indirect, special, incidental or consequential damages.

further agrees to indemnify the Funds, against any claim, damages, loss or liability (including reasonable attorneys' fees) arising out of any third party claims brought against an indemnified party that are found to constitute reckless disregard, willful misfeasance, bad faith, gross negligence, fraud or willful misconduct on the part of the indemnifying party.

12.

Duration and Termination. This Agreement will become effective as to a Fund upon execution or, if later, on the date that initial capital for such Fund is first provided to it and, unless sooner terminated as provided herein, the initial term will continue in effect through September 30, 2016. Hereafter, if not terminated as to a Fund, this Agreement will continue from year to year through September 30th for each Fund covered by this Agreement, as listed on Schedule A, provided that such continuation is specifically approved at least annually by the Board of Trustees or by vote of a majority of the outstanding voting securities of such Fund, and in either event approved also by a majority of the Trustees of the Trust who are not interested persons of the Trust, or of the Adviser, or of the Sub-Adviser. Notwithstanding the foregoing, this Agreement may be terminated as to a Fund at any time, without the payment of any penalty, on sixty days’ written notice by the Trust or Adviser, or on sixty days’ written notice by the Sub-Adviser. This Agreement will immediately terminate in the event of its assignment. (As used in this Agreement, the terms “majority of the outstanding voting securities,” “interested persons” and “assignment” have the same meaning of such terms as in the 1940 Act.) Sections 10 and 11 herein shall survive the termination of this Agreement.

In the event of termination, Adviser or Trust will remain liable to Sub-Adviser for any sub-advisory fees incurred pursuant to Section 8 above through termination, until the Sub-Adviser discontinues trading or the funds have been withdrawn from the Sub-Adviser’s management, whichever is earliest.

13.	Representations and Agreements of the Adviser. Adviser acknowledges, represents and warrants that:

If the Sub-Adviser is registered as a Commodity Trading Advisor under the CEA, the Adviser consents to the Sub-Adviser’s compliance with the alternative disclosure and recordkeeping standards available to exempt accounts under CFTC Regulation 4.7 with respect to a Fund’s trading in commodity interests, provided that the Sub-Adviser has duly filed a notice of claim for such relief pursuant to Regulation 4.7(d). The Adviser will take reasonable steps to cooperate with the Sub-Adviser in connection with establishing and maintaining such exemption under Regulation 4.7, including, upon request, confirming whether a Fund is a “qualified eligible person” as defined in Regulation 4.7.

If the Adviser is excluded from the definition of a commodity pool operator under CFTC Regulation 4.5 with respect to a Fund, the Adviser will furnish the Sub-Adviser with a copy of the notice of eligibility filed pursuant to Regulation 4.5 (c) with respect to such exclusion, or, if more recent, the most recent annual notice affirming the basis of such eligibility that has been filed pursuant to Regulation 4.5(c)(5).

The Adviser will immediately notify the Sub-Adviser to the extent required by applicable law in the event that the Adviser or any of its affiliates: (1) becomes aware that it is subject to a statutory disqualification that prevents Adviser from serving as an investment adviser pursuant to this Agreement; or (2) becomes aware that it is the

Page 12 of 17

subject of an administrative proceeding or enforcement action by the SEC or other regulatory authority; and

d)	The Adviser will immediately notify the Sub-Adviser if the Adviser suffers a material adverse change in its business that would materially impair its ability to pay Sub-Adviser or comply with any duties or responsibilities contained within this Agreement.

e)	The Trust is a “qualified institutional buyer” (“QIB”) as defined in Rule 144A under the 1933 Act, and the Adviser will promptly notify the Sub-Adviser if the Trust ceases to be a QIB;

The assets in the Funds are free from all liens and charges and the Trust undertakes that no liens or charges will arise from the acts or omissions of the Adviser and the Trust which may prevent the Sub-Adviser from giving a first priority lien or charge on the assets solely in connection with the Sub-Adviser’s authority to direct the deposit of margin or collateral to the extent necessary to meet the obligations of the Funds with respect to any investments made pursuant to the Prospectus; and

The Adviser acknowledges that the Sub-Adviser is not the compliance agent for the Funds or for the Adviser, and does not have access to all of the Funds’ books and records necessary to perform certain compliance testing. To the extent that the Sub-Adviser has agreed to perform the services specified in Section 3 hereof in accordance with applicable law (including Section 851 of the IRC, the Act and the Advisers Act (“Applicable Law”)) and in accordance with the Trust Documents, policies and determinations of the Board of Trustees of the Trust and the Adviser, and the Funds’ Prospectus (collectively the “Charter Requirements”) the Sub-Adviser shall perform such services based upon its books and records with respect to the Funds, and upon written instructions received from the Funds, the Adviser or the Trust’s administrator, and shall not be held responsible under this Agreement so long as it performs such services in accordance with this Agreement, the Charter Requirements and Applicable Law based upon such books and records and such instructions provided by the Funds, the Adviser or the Trust’s administrator. The Sub-Adviser shall be afforded a reasonable amount of time to implement any such instructions. (For example, if instructed not to trade on behalf of securities of certain specified Adviser or the Trust’s affiliates, the Sub-Adviser shall be notified and afforded five business days after receipt of such instruction to implement this trading restriction.)

14.	Obligations of Adviser. The Adviser agrees to provide the following prior to the commencement of the Sub-Adviser’s investment advisory services as specified under this Agreement:

a)	A list of first tier affiliates and second tier affiliates (i.e., affiliates of affiliates) of the Fund;

b)	A list of restricted securities for each Fund (including CUSIP, Sedol or other appropriate security identification);

c)	A copy of the current compliance procedures for each Fund; and

d)	A list of legal and compliance contacts.

The Adviser also agrees to promptly update the above referenced items in order to ensure their accuracy, completeness and/or effectiveness.

15.
