W I T N E S S E T H:

WHEREAS, the Trust is registered with the U.S. Securities and Exchange Commission (the “SEC”) as an open-end management investment company under the Investment Company Act of 1940, as amended (the “1940 Act”);

WHEREAS, the Adviser has, pursuant to an Investment Advisory Agreement with the Trust dated of the 1^st day of May, 2007 (the “Advisory Agreement”), been retained to act as investment adviser for certain of the series of the Trust that are listed on Exhibit A to this Agreement (each, a “Fund”);

WHEREAS, the Advisory Agreement permits the Adviser to delegate certain of its duties under the Advisory Agreement to other investment advisers, subject to the requirements of the 1940 Act; and

WHEREAS, the Adviser desires to retain Subadviser to assist it in the provision of a continuous investment program for that portion of each Fund’s assets that the Adviser will assign to the Subadviser, and Subadviser is willing to render such services subject to the terms and conditions set forth in this Agreement,

NOW, THEREFORE, the parties do mutually agree and promise as follows with respect to each Fund:

1. Appointment as Subadviser. The Adviser hereby appoints the Subadviser to act as investment adviser for and to manage that portion or all of the assets of the Fund that the Adviser from time to time upon reasonable prior notice allocates to, and puts under the control of, the Subadviser (the “Subadviser Assets”) subject to the supervision of the Adviser and the Board of Trustees of the Trust and subject to the terms of this Agreement. The Subadviser hereby accepts such appointment and, in such capacity, agrees to be responsible for the investment management of the Subadviser Assets. It is recognized that the Subadviser and

certain of its affiliates now act, and that from time to time hereafter may act, as investment adviser to one or more other investment companies and to fiduciary or other managed accounts and that the Adviser and the Trust do not and cannot object to such activities.

2. Duties of Subadviser.

(a) Investments. The Subadviser is hereby authorized and directed and hereby agrees, subject to the stated investment policies and restrictions of the Fund as set forth in the Fund’s prospectus and statement of additional information as currently in effect and, as soon as practical after the Trust, the Fund or the Adviser notifies the Subadviser in writing thereof, as supplemented or amended from time to time (collectively referred to hereinafter as the “Prospectus”) and subject to the directions of the Adviser and the Trust’s Board of Trustees, to monitor on a continuous basis the performance of the Subadviser Assets and to conduct a continuous program of investment, evaluation and, if appropriate, sale and reinvestment of the Subadviser Assets. Consistent with the foregoing, the Sub-Adviser shall have the authority to purchase, hold and sell investments for the Subadviser Assets without prior consultation with the Adviser or the Trusts’ Board of Trustees. The Adviser agrees to provide the Subadviser with such assistance as may be reasonably requested by the Subadviser in connection with the Subadviser’s activities under this Agreement, including, without limitation, providing information concerning the Fund, its funds available or to become available for investment, and generally as to the conditions of the Fund’s or the Trust’s affairs.

(b) Compliance with Applicable Laws and Governing Documents. In the performance of its services under this Agreement, the Subadviser shall act in conformity with the Prospectus and the Trust’s Agreement and Declaration of Trust and By-Laws as currently in effect and, as soon as practical after the Trust, the Fund or the Adviser notifies the Subadviser thereof, as supplemented, amended and/or restated from time to time (referred to hereinafter as the “Declaration of Trust” and “By-Laws,” respectively) and with the instructions and directions received in writing from the Adviser or the Trustees of the Trust and will conform to, and comply with, the requirements of the 1940 Act, the Internal Revenue Code of 1986, as amended (the “Code”), and all other applicable federal and state laws and regulations. Without limiting the preceding sentence, the Adviser promptly shall notify the Subadviser as to any act or omission of the Subadviser hereunder that the Adviser reasonably deems to constitute or to be the basis of any noncompliance or nonconformance with any of the Trust’s Declaration of Trust and By-Laws and the Prospectus, the instructions and directions received in writing from the Adviser or the Trustees of the Trust or the 1940 Act, the Code, and all other applicable federal and state laws and regulations. Notwithstanding the foregoing, the Adviser shall remain responsible for ensuring the Fund’s and the Trust’s overall compliance with the 1940 Act, the Code and all other applicable federal and state laws and regulations and the Subadviser is only obligated to comply with this subsection (b) with respect to the Subadviser Assets. The Adviser timely will provide the Subadviser with a copy of the minutes of the meetings of the Board of Trustees of the Trust to the extent they may affect the Fund or the services of the Subadviser, copies of any financial statements or reports made by the Fund to its shareholders, and any further materials or

information which the Subadviser may reasonably request to enable it to perform its functions under this Agreement.

The Adviser shall perform quarterly and annual tax compliance tests to ensure that the Fund is in compliance with Subchapter M and Section 817(h) of the Code. In connection with such compliance tests, the Adviser shall provide written notice to the Subadviser at least ten (10) business days prior to a calendar quarter end if the Subadviser Assets are out of compliance with the diversification requirements under either Subchapter M or Section 817(h). If the Adviser notifies the Subadviser that the Subadviser Assets are not in compliance with such requirements noted above, the Subadviser will take prompt action to bring the Subadviser Assets back into compliance in accordance with Adviser’s notice within the time permitted under the Code thereunder. Subadviser’s actions taken pursuant to Adviser’s notice shall not constitute any admission of wrongdoing by Subadviser and Subadviser shall be protected for acting in accordance with Adviser’s notice.

The Adviser will provide the Subadviser with reasonable advance notice of any change in the Fund’s investment objectives, policies and restrictions as stated in the Prospectus, and the Subadviser shall, in the performance of its duties and obligations under this Agreement, manage the Subadviser Assets consistent with such changes, provided that the Subadviser has received prompt notice of the effectiveness of such changes from the Trust or the Adviser. In addition to such notice, the Adviser shall provide to the Subadviser a copy of a modified Prospectus reflecting such changes. The Adviser acknowledges and will ensure that the Prospectus will at all times be in compliance with all disclosure requirements under all applicable federal and state laws and regulations relating to the Trust or the Fund, including, without limitation, the 1940 Act, and the rules and regulations thereunder, and that the Subadviser shall have no liability in connection therewith, except as to the accuracy of material information furnished in writing by the Subadviser to the Trust or to the Adviser specifically for inclusion in the Prospectus. The Subadviser hereby agrees to provide to the Adviser in a timely manner such information relating to the Subadviser and its relationship to, and actions for, the Trust as may be required to be contained in the Prospectus or in the Trust’s Registration Statement on Form N-1A.

(c) Voting of Proxies. The Adviser hereby delegates to the Subadviser the Adviser’s discretionary authority to exercise voting rights with respect to the securities and other investments in the Subadviser Assets and authorizes the Subadviser to delegate further such discretionary authority to a designee identified in a notice given to the Trust and the Adviser. The Subadviser, including, without limitation, its designee (for which the Subadviser shall remain liable, subject to the terms and conditions of this Agreement and to the same extent as if Subadviser had performed such services), shall have the power to vote, either in person or by proxy, all securities in which the Subadviser Assets may be invested from time to time and for which Subadviser timely receives a proxy, and shall not be required to seek or take instructions from, the Adviser, the Fund or the Trust or take any action with respect thereto. Subadviser (or its designee) shall vote any proxies received in a timely manner in accordance with Subadviser’s proxy voting policies and procedures as in effect from time to time. If both the Subadviser and another

entity managing assets of the Fund have invested the Fund’s assets in the same security, the Subadviser and such other entity will each have the power to vote its pro rata share of the Fund’s security.

The Subadviser has established a written procedure for proxy voting in compliance with current applicable rules and regulations, including, but not limited to, Rule 30b1-4 (Report of Proxy Voting Record) under the 0000 Xxx. The Subadviser will provide the Adviser or its designee, a copy of such procedure and establish a mutually acceptable process for the timely distribution of the Subadviser’s voting record with respect to the Fund’s securities and other information necessary for the Fund to complete information required by Form N-1A under the 1940 Act and the Securities Act of 1933, as amended (the “Securities Act”), Form N-PX under the 1940 Act, and Form N-CSR under the Xxxxxxxx-Xxxxx Act of 2002, as amended, respectively.

(d) Agent. Subject to any other written instructions of the Adviser or the Trust, the Subadviser is hereby appointed the Adviser’s and the Trust’s agent and attorney-in-fact for the limited purposes of executing account documentation, agreements, contracts and other documents as the Subadviser shall be requested by brokers, dealers, counterparties and other persons in connection with its management of the Subadviser Assets. The Subadviser agrees to provide the Adviser and the Trust with copies of any such agreements executed on behalf of the Adviser or the Trust upon Adviser’s reasonable request.

(e) Brokerage. The Subadviser is authorized, subject to the supervision of the Adviser and the general plenary authority of the Trust’s Board of Trustees, to establish and maintain accounts on behalf of the Fund with, and place orders for the investment and reinvestment, including, without limitation, purchase and sale of the Subadviser Assets with or through, such persons, brokers or dealers (including, to the extent permitted by applicable law, “affiliated persons” of Subadviser (as such term is defined under the 1940 Act)) (collectively “Brokers”) as Subadviser may elect and negotiate commissions to be paid on such transactions. The Subadviser, however, is not required to obtain the consent of the Adviser or the Trust’s Board of Trustees prior to establishing any such brokerage account. The Subadviser shall place all orders for the purchase and sale of portfolio investments for the Fund’s account with Brokers selected by the Subadviser. In the selection of such Brokers and the placing of such orders, the Subadviser shall seek to obtain the best execution available for each Fund in accordance with Subadviser’s best execution policies and applicable law, except to the extent it may be permitted to pay higher brokerage commissions for brokerage and research services, as provided below. In using its reasonable efforts to seek to obtain for the Fund the best execution available, the Subadviser, bearing in mind the best interests of the Fund at all times, shall consider all factors it deems relevant, including price, the size of the transaction, the breadth and nature of the market for the security, the difficulty of the execution, the amount of the commission, if any, the timing of the transaction, market prices and trends, the reputation, experience and financial stability of the Broker involved, and the quality of service rendered by the Broker in other transactions. Notwithstanding the foregoing, neither the Trust, the Fund nor the Adviser shall instruct the Subadviser to place orders with any particular Broker(s) with respect to the

Subadviser Assets. Subject to such policies as the Trustees may determine, or as may be mutually agreed to by the Adviser and the Subadviser, the Subadviser is authorized but not obligated to cause, and shall not be deemed to have acted unlawfully or to have breached any duty created by this Agreement or otherwise solely by reason of its having caused, the Fund to pay a Broker that provides brokerage and research services (within the meaning of Section 28(e) of the Securities Exchange Act of 1934) to the Subadviser an amount of commission for effecting a Subadviser Assets’ investment transaction that is in excess of the amount of commission that another Broker would have charged for effecting that transaction if, but only if, the Subadviser determines in good faith that such commission was reasonable in relation to the value of the brokerage and research services provided by such Broker viewed in terms of either that particular transaction or the overall responsibility of the Subadviser and its affiliates with respect to the accounts as to which it and its affiliates exercise investment discretion.

It is recognized that the services provided by such Brokers may be useful to the Subadviser in connection with the Subadviser’s and its affiliates’ services to other clients. On occasions when the Subadviser deems the purchase or sale of a security to be in the best interests of the Fund with respect to the Subadviser Assets as well as other clients of the Subadviser and its affiliates, the Subadviser, to the extent permitted by applicable laws and regulations, may, but shall be under no obligation to, aggregate the securities to be sold or purchased in order to obtain the most favorable price or lower brokerage commissions and efficient execution. In such event, allocation of securities so sold or purchased, as well as the expenses incurred in the transaction, will be made by the Subadviser in the manner the Subadviser considers to be the most equitable and consistent with its fiduciary obligations to each Fund and to such other clients. It is recognized that in some cases, this procedure may adversely affect the price paid or received by the Fund or the size of the position obtainable for, or disposed of by, the Fund with respect to the Subadviser Assets.

(f) Securities Transactions. The Subadviser and any affiliated person of the Subadviser will not purchase securities or other instruments from or sell securities or other instruments to the Fund; provided, however, the Subadviser or any affiliated person of the Subadviser may purchase securities or other instruments from or sell securities or other instruments to the Fund if such transaction is permissible under applicable laws and regulations, including, without limitation, the 1940 Act and the Advisers Act and the rules and regulations promulgated thereunder.

The Subadviser, on its own behalf and with respect to its Access Persons (as defined in subsection (e) of Rule 17j-1 under the 1940 Act), agrees to observe and comply with Rule 17j-1 and its Code of Ethics (which shall comply in all material respects with Rule 17j-1), as the same may be amended from time to time. On at least an annual basis, the Subadviser will comply with the reporting requirements of Rule 17j-1, which may include either (i) certifying to the Adviser that the Subadviser and its Access Persons have complied with the Subadviser’s Code of Ethics with respect to the Subadviser Assets or (ii) identifying any violations which have occurred with respect to the Subadviser Assets. The Subadviser will have also submitted its Code of Ethics for its

initial approval by the Board of Trustees no later than the date of execution of this agreement and subsequently within six months of any material change thereto.

(g) Books and Records. The Subadviser shall maintain separate detailed records as are required by applicable laws and regulations of all matters hereunder pertaining to the Subadviser Assets (the “Fund’s Records”), including, without limitation, brokerage and other records of all securities transactions. The Subadviser acknowledges that the Fund’s Records are property of the Trust; except to the extent that the Subadviser is required to maintain the Fund’s Records under the Advisers Act or other applicable law and except that the Subadviser, at its own expense, is entitled to make and keep a copy of the Fund’s Records for its internal files. The Fund’s Records shall be available to the Adviser or the Trust at any time upon reasonable request during normal business 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.

(h) Information Concerning Subadviser Assets and Subadviser. From time to time as the Adviser or the Trust reasonably may request in good faith, the Subadviser will furnish the requesting party reports on portfolio transactions and reports on the Subadviser Assets, all in such reasonable detail as the parties may reasonably agree in good faith. The Subadviser will also inform the Adviser in a timely manner of material changes in portfolio managers responsible for Subadviser Assets, any changes in the ownership or management of the Subadviser, or of material changes in the control of the Subadviser. Upon the Trust’s or the Adviser’s reasonable request in good faith, the Subadviser will make available its officers and employees to meet with the Trust’s Board of Trustees to review the Subadviser Assets via telephone on a quarterly basis and in person on a less frequent basis as agreed upon by the parties.

Subject to the other provisions of this Agreement, the Subadviser will also provide such reasonable information/certifications or perform such reasonable additional acts with respect to the Subadviser Assets as are necessary for the Trust or the Adviser to comply with their respective obligations under applicable laws, regulations and/or policies of the Trust’s Board of Trustees, including, without limitation, requirements of or pertaining to the Code, the 1940 Act, the Advisers Act, and the Securities Act, and any rule or regulation thereunder.

(i) Custody Arrangements. The Trust or the Adviser shall notify the Subadviser of the identities of its custodian banks and the custody arrangements therewith with respect to the Subadviser Assets and shall give the Subadviser written notice of any changes in such custodian banks or custody arrangements. The Subadviser 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 (and in such form as mutually agreed by the parties) relating to all transactions concerning the Subadviser Assets. The Trust shall instruct its custodian banks to (A) carry out all investment instructions as may be directed by the Subadviser with respect to the Subadviser Assets (which instructions may be orally given if confirmed in writing); and (B) provide the Subadviser with all operational information necessary for the Subadviser to trade the Subadviser Assets on behalf of the Fund. The Subadviser

shall have no liability for the acts or omissions of the authorized custodian(s), unless (subject in all cases to the terms and conditions of this Agreement) such act or omission is required by and taken in reliance upon instructions given to the authorized custodian(s) by a representative of the Subadviser properly authorized (pursuant to written instruction by the Adviser) to give such instructions.

(j) Valuation Assistance. The Subadviser shall not be responsible for the provision of administrative, bookkeeping or accounting services to the Trust. The Adviser hereby acknowledges that the Subadviser is not responsible for pricing portfolio securities. Notwithstanding the foregoing, the Subadviser agrees that, upon request of the Adviser, it shall reasonably assist the Adviser in obtaining prices for portfolio securities and, to the extent it may lawfully do so, provide the Adviser with reasonable information, data or analyses in its possession. The Adviser and the Trust acknowledge that any such information, data or analyses may be proprietary to the Subadviser or otherwise consist of nonpublic information, agree that nothing in this Agreement shall require Subadviser to provide any information, data or analysis in contravention of applicable legal or contractual requirements, and agree to use any such information only for the purpose of pricing portfolio securities and to maintain their confidentiality.

(k) Independent Contractor. In the performance of its services hereunder, the Subadviser is and shall be an independent contractor and unless otherwise expressly provided herein or otherwise authorized in writing, shall have no authority to act for or represent the Fund, the Trust or the Adviser in any way or otherwise be deemed an agent of the Fund, the Trust or the Adviser.

(l) Expenses. During the term of this Agreement, Subadviser will pay all expenses incurred by it in connection with its activities under this Agreement. The Subadviser shall, at its sole expense, employ or associate itself with such persons as it believes to be particularly fitted to assist it in the execution of its duties under this Agreement. The Subadviser 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 Subadviser Assets, 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 Subadviser Assets, organizational and offering expenses (which include, but are not limited to, out-of-pocket expenses, but not overhead or employee costs of the Subadviser); 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, 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

The Subadviser shall keep and supply to the Trust and the Adviser reasonable records of all such expenses.
