-1-

SECTION 1. Appointment of Sub-Adviser.

The Adviser hereby appoints the Sub-Adviser to act as investment sub-adviser to the Fund for the period and on the terms herein set forth, and the Trust on behalf of the Fund and the shareholders of the Fund have approved such appointment. The Sub-Adviser accepts such appointment and agrees to render the services herein set forth, for the compensation herein provided. The Sub-Adviser acknowledges that such appointment as investment sub-adviser to the Fund may be limited to those Fund assets allocated to the Sub-Adviser by the Adviser, which may be changed from time to time at the sole discretion of the Adviser. Where the context so requires, references to “the Fund” in this Agreement shall refer to those Fund assets allocated to the Sub-Adviser by the Adviser. The Sub-Adviser shall for purposes herein be deemed an independent contractor and shall, except as expressly provided or authorized, have no authority to act for or represent the Trust, the Funds or the Adviser in any way, or otherwise be deemed an agent of the Trust, the Funds or the Adviser. For the avoidance of doubt, the Sub-Adviser shall not be permitted to delegate any of its obligations under this Agreement.

SECTION 2. Duties of Sub-Adviser.

The Sub-Adviser, at its own expense, shall furnish the following services and facilities to the Fund:

(a) Investment Program. The Sub-Adviser shall (i) furnish continuously an investment program for the Fund, including but not limited to allocating assets to other third-party sub-advisers based upon the Sub-Adviser’s asset allocation model, (ii) determine (subject to the overall supervision of the Adviser and the Trust’s Board of Trustees) the investments to be purchased, held, sold or exchanged by the Fund and the portion, if any, of the assets of the Fund to be held uninvested, (iii) make changes in the investments of the Fund, (iv) review and certify in writing, at such times as shall be reasonably requested by the Adviser, that the information stated in those sections specifically identified to the Sub-Adviser by the Adviser of the Trust’s registration statement, as currently in effect and as amended or supplemented from time to time (referred to collectively as the “Registration Statement”) and as filed with the Securities and Exchange Commission (“SEC”), any proxy statement, any annual or semi-annual report to investors in the Fund, any other reports filed with the SEC and any marketing material of the Fund, to the extent such sections relate to the Sub-Adviser and its management of the Fund or the applicable portion of the Fund’s assets, is true, correct and complete to the best of its knowledge, (v) at such times as shall be reasonably requested by the Adviser, cooperate with the Adviser to ensure the accuracy of other information in such documents and materials relating to the Fund, including the Fund’s risk disclosures and financial information and the Sub-Adviser’s investment performance in its management of the Fund, and (vi) vote, exercise consents and exercise all other rights pertaining to such investments. The Sub-Adviser shall be subject always to the provisions of the organizational documents of the Trust, the Registration Statement of the Trust with respect to the Fund and its shares of beneficial interest, including the Fund’s prospectus(es) and statement of additional information, and the 1940 Act, in each case as from time to time amended and in effect. The Sub-Adviser shall carry out its

-2-

responsibilities under this Agreement in compliance with: (vii) the Fund’s investment objective, policies and restrictions as set forth in the Registration Statement of the Trust and the Fund’s prospectus and statement of additional information; (viii) the organizational documents of the Trust; (ix) all investment guidelines, policies, procedures or directives of the Trust or the Adviser as provided to the Sub-Adviser (“Investment Guidelines”); (x) the 1940 Act and the rules promulgated thereunder; (xi) the Investment Advisers Act of 1940, as amended (“Advisers Act”), and the rules promulgated thereunder; and (xii) other applicable federal and state laws and related regulations. To the extent that the Investment Guidelines applicable to the portion of the Fund’s assets allocated to the Sub-Adviser are inconsistent with the investment restrictions applicable to the Fund’s total assets as set forth in the Registration Statement, the Sub-Adviser shall comply with thepolicies, procedures and directives as set forth in the Investment Guidelines. The Adviser shall promptly notify the Sub-Adviser in writing of changes to (vii), (viii) or (ix) above and shall consult with the Sub-Adviser before making any changes relating solely to the Fund’s investment objective, policies and restrictions as set forth in the Registration Statement, as well as to the policies, procedures and directives set forth in the Investment Guidelines.

(b) Portfolio Transactions. The Sub-Adviser shall place all orders for the purchase and sale of portfolio securities for the account of the Fund with brokers or dealers selected by the Sub-Adviser, although the Fund will pay the actual brokerage commissions on portfolio transactions in accordance with Section 3(d) of the Advisory Agreement. For that limited purpose, the Sub-Adviser is authorized as the agent of the Fund to give instructions to the custodian of the Fund as to deliveries of securities or other investments and payments of cash for the account of the Fund.

In placing portfolio transactions for the Fund, it is recognized that the Sub-Adviser will use its best efforts to secure the most favorable price and efficient execution. Consistent with this policy, the Sub-Adviser may consider the financial responsibility, research and investment information and other services provided by brokers or dealers who may effect or be a party to any such transaction or other transactions to which other clients of the Sub-Adviser may be a party. It is understood that neither the Fund nor the Sub-Adviser has adopted a formula for allocation of the Fund’s investment transaction business. It is also understood that it is desirable for the Fund that the Sub-Adviser have access to supplemental investment and market research and security and economic analysis provided by brokers who may execute brokerage transactions at a higher cost to the Fund than would otherwise result when allocating brokerage transactions to other brokers on the basis of seeking the most favorable price and efficient execution. Therefore, subject to Section 28(e) of the Securities Exchange Act of 1934 and any restrictions and guidelines established by the Trust’s Board of Trustees, the Sub-Adviser is authorized to place orders for the purchase and sale of securities for the Fund with such brokers. It is understood that the services provided by such brokers may be useful or beneficial to the Sub-Adviser in connection with its services to other clients.

On occasions when the Sub-Adviser deems the purchase or sale of a security to be in the best interest of the Fund as well as other clients, the Sub-Adviser, to the extent permitted

-3-

by applicable laws and regulations, may, but shall be under no obligation to, aggregate the securities to be so sold or purchased in order to obtain the most favorable price or lower brokerage commissions and efficient execution. In such event, allocation of the securities so purchased or sold, as well as the expenses incurred in the transaction, will be made by the Sub-Adviser in the manner it considers to be the most equitable and consistent with its fiduciary obligations to the Fund and to such other clients.

(c) Fair Valuation. In accordance with procedures adopted by the Trust’s Board of Trustees, as amended from time to time, the Sub-Adviser is responsible for assisting the Adviser in determining the fair valuation of any illiquid portfolio securities held by the Fund and will assist the Trust’s accounting services agent or the Adviser to obtain independent sources of market value for all other portfolio securities.

Further, the Sub-Adviser shall be responsible to ensure that the Fund and/or the Adviser is promptly notified of any and all instances in which the Sub-Adviser knows or should have reason to know that the available price or value of a portfolio security does not represent the fair value of the instrument, or that there is no price or value available from any source with respect to a particular instrument and that such instrument should accordingly be subject to a fair valuation determination in accordance with procedures adopted by the Board of Trustees, as amended from time to time.

SECTION 3. Delivery of Documents.

The Adviser has furnished the Sub-Adviser with true and complete copies properly certified or authenticated of each of the following documents:

(a)

Organizational documents of the Trust;

(b)

Registration Statement of each Fund;

(c)

The Investment Guidelines;

(d)

The Advisory Agreement;

(e)

A list of affiliated brokers and underwriters of a Fund for compliance with applicable provisions of the 1940 Act; and

(f)

A list of affiliated issuers of the Fund and/or the Adviser restricted from purchase by a Fund.

The Adviser will provide to the Sub-Adviser copies properly certified or authenticated of amendments or supplements to any of these materials as soon as practical after such materials become available.

-4-

SECTION 4. Allocation of Expenses.

During the term of this Agreement, the Sub-Adviser will bear all expenses incurred by it in connection with its investment sub-advisory services under this Agreement. The Sub-Adviser does not assume nor shall it pay any expenses for Fund operations and activities. For the avoidance of doubt, unless the prospectus(es) or statement of additional information of the Fund provides otherwise, the expenses to be borne by the Fund shall include, without limitation, those items listed in Section 3 of the Advisory Agreement.

SECTION 5. Sub-Advisory Fee.

(a) In return for its advisory services, the Adviser will pay the Sub-Adviser a monthly fee, computed and accrued daily, based on an annual rate of 0.250% of the “Average Daily Managed Assets” of such portion of the Fund’s assets allocated to the Sub-Adviser. “Average Daily Managed Assets” shall mean the average daily value of the assets of the Fund allocated to the Sub-Adviser, less accrued liabilities of the Fund related or allocated to such portion of the Fund’s assets allocated to the Sub-Adviser (other than the aggregate amount of any outstanding borrowings constituting financial leverage). For the avoidance of doubt, assets allocated by the Sub-Adviser to other sub-advisers pursuant to Section 2(a) of this Agreement will not be considered to have been allocated to Sub-Adviser for purposes of determining Average Daily Managed Assets, and the Sub-Adviser will not receive any fees with respect to such assets. If this Agreement becomes effective subsequent to the first day of a month or shall terminate before the last day of a month, compensation for such month shall be computed in a manner consistent with the calculation of the fees payable on a monthly basis. The accrued fees will be payable monthly no later than the fifteenth (15) business day following the end of each month during which this Agreement is in effect.

(b) The Adviser agrees to direct the Fund’s administrator to pay the Sub-Adviser the compensation payable pursuant to Section 5(a) out of the assets of the Fund; provided, however, that in such case the compensation payable to the Sub-Adviser by the Adviser hereunder will be reduced by the amount of any compensation paid directly by the Fund to the Sub-Adviser.

To the extent the Sub-Adviser allocates any assets to third-party sub-advisers as contemplated by clause (i) of Section 2(a), the fees payable to such third-party sub-advisers shall not be payable by the Sub-Adviser out of the fees paid by the Adviser to the Sub-Adviser pursuant to this Section 5 but shall be paid pursuant to the terms and conditions of the sub-advisory agreement entered between such third-party sub-adviser and the Adviser.

SECTION 6. Compliance with Applicable Regulations.

In performing its duties hereunder, the Sub-Adviser:

The Sub-Adviser shall provide reasonable assistance to the Fund and the CCO in complying with Rule 38a-1 under the 1940 Act and, upon the request of the Fund and/or the CCO, including in connection with the CCO’s annual written report to the Board required pursuant to Rule 38a- 1, the Sub-Adviser agrees to provide reports and certifications from the Sub-Adviser’s Chief Compliance Officer regarding: (i) the adequacy and operation of the Compliance Policies and Procedures and any material changes made or recommended to be made to those policies and procedures; and (ii) the effectiveness of their implementation.

The Sub-Adviser shall provide the notice contemplated by clauses (i) and (ii) above within a reasonable period of time after the event giving rise to

The Sub-Adviser shall vote proxies on behalf of the Fund in a manner deemed by the Sub-Adviser to be in the best interests of the Fund pursuant to the Sub-Adviser’s written Proxy Voting Policies and Procedures. The Sub-Adviser shall provide disclosure regarding the Proxy Voting Policies and Procedures in accordance with the requirements of Form N-1A for inclusion in the Registration Statement of the Trust. The Sub-Adviser shall report to the Adviser in a timely manner a record of all proxies voted, in such form and format that complies with acceptable federal statutes and regulations (e.g., requirements of Form N-PX). The Sub-Adviser shall certify at least annually or more often as may reasonably be requested by the Adviser, as to its compliance with its Proxy Voting Policies and Procedures.

Agrees that it will maintain for the Fund all and only such records as required under Rules 31a-1 and 31a-2 under the 1940 Act in respect to its services hereunder and that such records are the property of the Fund and further agrees to surrender promptly to the Fund any such records upon the Fund’s request all in accordance with Rule 31a-3 under the 1940 Act, provided that the Sub-Adviser may retain a copy of those records for compliance purposes.

Agrees to regularly report to the Adviser on the investment program for the Fund and the issuers and securities represented in the Fund, and will furnish the Adviser, with respect to the Fund, such periodic and special reports as the Board and the Adviser may reasonably request or as may be required by applicable law.

-7-

upon its activities, functions or operations; suspended or revoked its registration or ability to serve as an investment adviser; or has commenced proceedings or an investigation that can reasonably be expected to result in any of these actions; (ii) upon having a reasonable basis for believing that the Fund has ceased to qualify or might not qualify as a regulated investment company under Subchapter M of the Code; and (iii) upon having a reasonable basis for believing that the Fund has ceased to comply with the diversification provisions of Section 8 17(h) of the Code or the regulations thereunder. The Sub-Adviser further agrees to notify in writing the Adviser and Fund promptly of any material fact known to the Sub-Adviser respecting or relating to the Sub-Adviser that should be but is not contained in the Registration Statement of the Trust, or any amendment or supplement thereto, or of any statement contained therein regarding the Sub-Adviser that becomes untrue in any material respect.

(i) The Adviser’s breach of its duties under this Agreement; or

(ii) any bad faith, willful misfeasance, reckless disregard or gross negligence on the part of the Adviser or any of its directors, officers or employees in the performance of the Adviser’s duties and obligations under this Agreement, except to the extent such loss results from the Sub-Adviser’s own willful misfeasance, bad faith, reckless disregard or gross negligence in the performance of Sub-Adviser’s duties and obligations under this Agreement.

-11-

(b) By the Trust.

(i) The Trust agrees to indemnify and hold the Sub-Adviser, its officers and directors, and any person who controls the Sub-Adviser within the meaning of Section 15 of the 1933 Act (each, a “Sub-Adviser Indemnitee”) harmless from any and all direct or indirect liabilities, losses or damages (including reasonable attorneys’ fees) arising out of any claim, demand, action, suit or proceeding arising out of any misrepresentation of a material fact or the omission of a fact necessary to make information not misleading in the Registration Statement, any proxy statement, or any annual or semi-annual report to investors in the Fund (other than a misstatement or omission relating to disclosure about the Sub-Adviser approved by the Sub-Adviser or provided to the Adviser or the Trust by the Sub-Adviser).

(ii) As to any matter disposed of by settlement or a compromise payment by such Sub-Adviser Indemnitee, pursuant to a consent decree or otherwise, no indemnification either for said payment or for any other expenses shall be provided unless there has been a determination that such settlement or compromise is in the best interests of the Trust and that such Sub-Adviser Indemnitee appears to have acted in good faith in the reasonable belief that such Sub-Adviser Indemnitee’s action was in the best interests of the Trust and did not involve willful misfeasance, bad faith, gross negligence or reckless disregard of the duties involved in the conduct of such Sub-Adviser Indemnitee’s position (such conduct, “Disabling Conduct”). With respect to any action, suit or other proceeding voluntarily prosecuted by any Sub-Adviser Indemnitee as plaintiff, indemnification shall be mandatory only if the prosecution of such action, suit or other proceeding by such Sub-Adviser Indemnitee was authorized by a majority of the full Board of Trustees of the Trust. Notwithstanding the foregoing, the Trust shall not be obligated to provide any such indemnification to the extent such provision would waive any right that the Trust cannot lawfully waive.

(iii) All determinations with respect to indemnification hereunder shall be made (1) by a final decision on the merits by a court or other body of competent jurisdiction before whom the proceeding was brought that such Sub-Adviser Indemnitee is not liable by reason of Disabling Conduct or, (2) in the absence of such a decision, by (i) a majority vote of a quorum of the Trustees of the Trust who are neither “interested persons” of the Trust (as defined in Section 2(a)(19) of the 0000 Xxx) nor parties to the proceeding, or (ii) if such a quorum is not obtainable or even if obtainable, if a majority vote of such quorum so directs, independent legal counsel in a written opinion.

The Sub-Adviser agrees to indemnify and hold the Adviser, its officers and directors, and any person who controls the Adviser within the meaning of Section 15 of the 1933 Act, and the Trust harmless from any and all direct or indirect liabilities, losses

-12-

or damages (including reasonable attorneys’ fees) arising out of any claim, demand, action, suit or proceeding arising out of:

(i) any misrepresentation of a material fact or the omission of a fact necessary to make information not misleading in the Registration Statement, any proxy statement, any annual or semi-annual report to investors in the Fund, any other reports filed with the SEC or any marketing material of the Fund relating to disclosure about the Sub-Adviser approved by the Sub-Adviser in writing or provided to the Adviser or the Trust by the Sub-Adviser;

(ii) Sub-Adviser’s breach of its duties under this Agreement; or

(iii) any bad faith, willful misfeasance, reckless disregard or gross negligence on the part of the Sub-Adviser or any of its directors, officers or employees in the performance of the Sub-Adviser’s duties and obligations under this Agreement, except to the extent such loss results from the Trust’s or the Adviser s own willful misfeasance, bad faith, reckless disregard or gross negligence in the performance of their respective duties and obligations under the Advisory Agreement or this Agreement.

SECTION 11. Duration and Termination of this Agreement.

(a) Duration. This Agreement shall become effective on the date first set forth above, such date being the date on which this Agreement has been executed following: (1) the approval of the Trust’s Board of Trustees, including approval by a vote of a majority of the Trustees who are not “interested persons” (as defined in the 0000 Xxx) of the Fund, cast in person at a meeting called for the purpose of voting on such approval; and (2) the approval by a “vote of a majority of the outstanding voting securities” (as defined in the 0000 Xxx) of the Fund. Unless terminated as herein provided, this Agreement shall remain in full force and effect until the date that is two years after the effective date of this Agreement. Subsequent to such initial period of effectiveness, this Agreement shall continue in full force and effect, subject to paragraph 11(c), so long as such continuance is approved at least annually (a) by either the Trust’s Board of Trustees or by a “vote of a majority of the outstanding voting securities” (as defined in the 0000 Xxx) of the Fund and (b) in either event, by the vote of a majority of the Trustees of the Fund who are not parties to this Agreement or “interested persons” (as defined in the 0000 Xxx) of any such party, cast in person at a meeting called for the purpose of voting on such approval.

(b) Amendment. No provision of this Agreement may be amended, waived, discharged or terminated orally, but only by an instrument in writing signed by the party against which enforcement of the amendment, waiver, discharge or termination is sought. No material amendment to this Agreement shall be effective until approved by a vote of a majority of the Fund’s outstanding voting securities, unless the Trust receives an SEC exemptive order or opinion of counsel, or the issue is the subject of a position of the SEC or its staff permitting it to modify the Agreement without such vote (including but not limited to the interpretation thereof that amendments that do not increase the

-13-

compensation of the Sub-Adviser or otherwise fundamentally alter the relationship of the Trust with the Sub-Adviser do not require shareholder approval if approved by the requisite majority of the Trust’s Trustees who are not “interested persons” (as defined in the 0000 Xxx) of the Trust).

(c) Termination. This Agreement may be terminated (i) at any time, without payment of any penalty, by vote of the Trust’s Board of Trustees, or by a “vote of a majority of the outstanding voting securities” (as defined in the 0000 Xxx) of the Fund, (ii) at any time, without payment of a penalty, by the Adviser (1) upon no less than 60 days’ prior written notice to the Sub-Adviser; (2) upon material breach by the Sub-Adviser of any of the representations and warranties set forth in this Agreement; or (3) if the Sub-Adviser becomes unable to discharge its duties and obligations under this Agreement, including circumstances such as financial insolvency of the Sub-Adviser or other circumstances that could adversely affect the Fund, or (iii) by the Sub-Adviser upon no less than 60 days’ prior written notice to the Adviser. All rights to compensation under this Agreement shall survive the termination of this Agreement. 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 thirty (30) days of the date of termination.

(d) Automatic Termination. This Agreement shall automatically and immediately terminate in the event of its “assignment” (as defined in the 0000 Xxx) or upon termination of the Advisory Agreement.

SECTION 12. Prohibited Conduct.

In providing the services described in this Agreement, the Sub-Adviser will not consult with any other investment advisory firm that provides investment advisory services to any investment company sponsored by the Adviser, including the Fund, regarding transactions in portfolio securities or other portfolio investments of the Fund.

SECTION 13. Services Not Exclusive.

The services of the Sub-Adviser to the Fund hereunder are not to be deemed exclusive, and the Sub-Adviser (and its affiliates) shall be free to render similar services to others so long as its services hereunder are not impaired thereby; provided, however, that the Sub-Adviser will undertake no activities that, in its reasonable good faith judgment, will adversely affect the performance of its obligations under this Agreement. In addition, the parties may enter into other agreements pursuant to which the Sub-Adviser provides administrative or other, non-investment advisory services to the Fund, and the Sub-Adviser may be compensated for such other services.

SECTION 14. Confidentiality.

During the term of this Agreement, and at all times thereafter, the Sub-Adviser shall not itself, or assist anyone else to, directly or indirectly, disclose to any person or entity Confidential Information of the Adviser, the Trust or the Fund, now known or subsequently learned by the

-14-

Sub-Adviser, provided that the Sub-Adviser may disclose Confidential Information to the extent reasonably necessary to perform its duties under this Agreement such as to broker-dealers, lawyers, accountants and other agents and, provided, further, Confidential Information may be disclosed to the extent required by law or by an order or decree of any court or other governmental authority; provided, however, that the Sub-Adviser will, if legally compelled to disclose such information: (i) provide the Adviser with prompt written notice of that fact so that the Adviser may attempt to obtain a protective order or other appropriate remedy and/or waive compliance with the provisions of this Agreement; and (ii) endeavor to obtain assurance that confidential treatment will be accorded the information so disclosed. “Confidential Information” shall mean any information, whether written or oral, and materials furnished to or obtained by the Sub-Adviser, including but not limited to that which relates to the Adviser, the Trust, the Fund, and their affiliates, clients, customers, vendors, or other third party’s research, development, trade secrets, techniques, processes, procedures, plans, policies, business affairs, marketing activities, discoveries, hardware, software, screens, specifications, designs, drawings, data and other information and materials, regardless of its form, other than information in the public domain.

In addition, the Adviser and the Sub-Adviser each agree, during the term of this Agreement, not to (and to cause its respective affiliates and its and its affiliates’ directors, officers, employees, agents, advisors, financing sources and representatives not to) initiate or maintain contact (except for those contacts made in the ordinary course of business or in the course of performance of its obligations under this Agreement) with any officer, director, employee, or agent of the other party or its affiliates regarding the other party’s business, operations, prospects or finances, except with the other party’s express written consent. In addition, each of the Adviser and the Sub-Adviser agree that, during the term of this Agreement, neither it nor any of its affiliates will, directly or indirectly, solicit the employment of or hire any current officer or employee of the other party or its affiliates with whom such party comes into contact in connection with the performance of its obligations under this Agreement, but only for so long as such officer or employee is employed by the other party or its affiliates. The phrase “solicit the employment of” (and any hiring resulting from such solicitation) shall not be deemed to include (i) general solicitation of employment not specifically directed towards employees of the other party or (ii) responding to unsolicited requests for employment.

SECTION 15. Notices.

Notices under this Agreement shall be in writing and shall be addressed, and delivered or mailed postage prepaid, to the other party at such address as such other party may designate from time to time for the receipt of such notices. Until further notice to the other party, the address of the Trust and the Adviser for this purpose shall be 000 Xxxxxxxx Xxxxx, Xxxxx 000, Xxxxxx, Xxxxx 00000 and the address of the Sub-Adviser for this purpose shall be 0000 Xxxxxx Xxxxxx, Xxxxxxxx, Xxxxxxxxxxx 00000, Attention: General Counsel.

SECTION 16. Governing Law; Severability; Counterparts.

This Agreement shall be construed in accordance with the laws of the State of Delaware and the applicable provisions of the 1940 Act. To the extent that applicable law of the State of

-15-

Delaware, or any of the provisions herein, conflict with applicable provisions of the 1940 Act, the latter shall control. If any provision of this Agreement shall be held or made invalid by a court decision, statute, rule or otherwise, the remainder of this Agreement shall not be affected thereby. This Agreement may be executed in any number of counterparts, each of which shall be deemed to be an original, but such counterparts shall, together, constitute only one instrument.

SECTION 17. Miscellaneous.

Where the effect of a requirement of the 1940 Act reflected in or contemplated by any provisions of this Agreement is altered by a rule, regulation or order of the SEC, whether of special or general application, such provision shall be deemed to incorporate the effect of such rule, regulation or order.
