WHEREAS, the Adviser desires to retain the Sub-Adviser to furnish investment advisory services for the Fund, upon the terms and conditions hereafter set forth;

NOW, THEREFORE, in consideration of the mutual covenants herein contained, the parties hereto agree as follows:

1. Appointment. The Adviser hereby appoints the Sub-Adviser to provide certain sub-investment advisory services to the Fund for the period and on the terms set forth in this Agreement. Sub-Adviser accepts such appointment and agrees to furnish the services herein set forth for the compensation herein provided.

2. Services to be Performed. Subject always to the supervision of the Adviser and the Fund’s Board of Trustees, the Sub-Adviser will furnish an investment program in respect of, make investment decisions for, and place all orders for the purchase and sale of securities for the portion of the Fund’s investment portfolio allocated by the Adviser to the Sub-Adviser, all on behalf of the Fund and consistent with the investment objectives, policies and restrictions of the Fund, as such objectives, policies and restrictions may subsequently be changed by the Fund’s Board of Trustees and publicly described and as the Sub-Adviser is notified of such changes. In the performance of its duties, the Sub-Adviser will satisfy its fiduciary duties to the Fund, will monitor the Fund’s investments in securities selected for the Fund by the Sub-Adviser hereunder, and will comply with the provisions of the Fund’s Declaration of Trust and By-laws, as amended from time to time, and the investment objectives, policies and restrictions of the Fund, to the extent the Sub-Adviser has been notified of such objectives, policies and restrictions. The Adviser will provide the Sub-Adviser with current copies of the Fund’s Declaration of Trust and By-laws and any amendments thereto, and any written objectives, policies, procedures or limitations as they may be relevant to the Sub-Adviser’s performance under this Agreement. The Sub-Adviser and the Adviser will each make its officers and employees available to the other from time to time at reasonable times to review investment policies of the Fund and to consult with each other regarding the investment affairs of the Fund. The Sub-Adviser will report to the Fund’s Board of Trustees and to the Adviser with respect to the implementation of such program.

The Sub-Adviser will vote proxies solicited by or with respect to the issuers of securities in which assets of the Fund allocated by the Adviser to the Sub-Adviser are invested consistent with the Sub-Adviser’s proxy voting guidelines, as in effect from time to time, and the best interests of the Fund. The Sub-Adviser will maintain appropriate records detailing its voting of proxies on behalf of the Fund and upon reasonable request will provide a report setting forth the proposals voted on and how the Fund’s shares were voted, including the name of the corresponding issuers.

The Sub-Adviser is authorized to select the brokers or dealers that will execute the purchases and sales of portfolio securities for the Fund, and is directed to use its commercially reasonable efforts to obtain best execution, which includes most favorable net results and execution of the Fund’s orders, taking into account all appropriate factors, including price, dealer spread or commission, size and difficulty of the transaction and research and other services, if any, that may be provided. It is understood that the Sub-Adviser will not be deemed to have acted unlawfully, or to have breached a fiduciary duty to the Fund, or be in breach of any obligation owing to the Fund under this Agreement, or otherwise, solely by reason of its having caused the Fund to pay a member of a securities exchange, a broker or a dealer a commission for effecting a securities transaction for the Fund in excess of the amount of commission another member of an exchange, broker or dealer would have charged if the Sub-Adviser determined in good faith that the commission paid was reasonable in relation to the brokerage or research services provided by such member, broker or dealer, viewed in terms of that particular transaction or Sub-Adviser’s overall responsibilities with respect to its accounts, including the Fund, as to which it exercises investment discretion. In addition, if in the judgment of the Sub-Adviser, the Fund would be benefited by supplemental services, the Sub-Adviser is authorized to pay spreads or commissions to brokers or dealers furnishing such services in excess of spreads or commissions that another broker or dealer may charge for the same transaction, provided that the Sub-Adviser determined in good faith that the commission or spread paid was reasonable in relation to the services provided. The Sub-Adviser will properly communicate to the officers and trustees of the Fund such information relating to transactions for the Fund as they may reasonably request. In no instance will the Fund’s portfolio securities be purchased from or sold to the Adviser, the Sub-Adviser or any affiliated person of the Fund, the Adviser or the Sub-Adviser, except as may be permitted under the 1940 Act.

The Sub-Adviser further agrees that it:

(a) will use the same degree of skill and care in providing such services as it uses in providing services to fiduciary accounts for which it has investment responsibilities;

(b) will conform to all applicable Rules and Regulations of the Securities and Exchange Commission in all material respects and in addition will conduct its activities under this Agreement in accordance with any applicable regulations of any governmental authority pertaining to its investment advisory activities;

(c) will report regularly to the Adviser and to the Board of Trustees of the Fund and will make appropriate persons available for the purpose of reviewing with representatives of the Adviser and the Board of Trustees on a regular basis at reasonable times the management of the Fund including, without limitation, review of the general investment

strategies of the Fund with respect to the portion of the Fund’s portfolio allocated to the Sub-Adviser and the performance of the Fund’s investment portfolio allocated to the Sub-Adviser in relation to standard industry indices and general conditions affecting the marketplace, and will provide various other reports from time to time as reasonably requested by the Adviser;

(d) will prepare such books and records with respect to the Fund’s securities transactions for the portion of the Fund’s investment portfolio allocated to Sub-Adviser as reasonably requested by Manager and will furnish Manager and the Fund’s Board of Trustees such periodic and special reports as Manager or the Board may reasonably request;

(e) will monitor the pricing of portfolio securities and events relating to the issuers of those securities and the markets in which the securities trade in the ordinary course of managing the portfolio securities of the Fund, and will notify the Adviser promptly of any issuer-specific or market events or other situations that occur (particularly those that may occur after the close of a foreign market in which the securities may primarily trade but before the time at which the Fund’s securities are priced on a given day) that may materially impact the pricing of one or more securities in the Sub-Adviser’s portion of the portfolio; and in addition, the Sub-Adviser will assist the Adviser in evaluating the impact that such an event may have on the net asset value of the Fund and in determining a recommended fair value of the affected security or securities; and

(f) will not consult with any other sub-adviser of the Fund or any other sub-adviser to a fund under common control with the Fund concerning transactions of the Fund in securities or other assets.

(d) will immediately notify the Adviser of the occurrence of any event that would disqualify the Sub-Adviser from serving as an investment adviser of an investment company pursuant to Section 9(a) of the 1940 Act or otherwise.

5. Expenses. During the term of this Agreement, the Sub-Adviser will pay all expenses incurred by it in connection with its activities under this Agreement other than the cost of securities (including brokerage commissions and other related expenses) purchased for the Fund.

6. 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 therefor, a per annum portfolio management fee of 0.39% of the Sub-Adviser’s allocation of the Fund’s managed assets. “Managed assets” for this purpose means the total assets of the Fund, minus the sum of its accrued liabilities (other than Fund liabilities incurred for the express purpose of creating effective leverage).

The portfolio management fee shall accrue on each calendar day, and shall be payable monthly on the first business day of the next succeeding calendar month. The daily fee accrual shall be computed by multiplying the fraction of one divided by the number of days in the calendar year by the applicable annual fee rate, and multiplying this product by the managed assets of the Fund allocated by the Adviser to the Sub-Adviser, determined in the manner established by the Fund’s Board of Trustees, as of the close of business on the last preceding business day on which the Fund’s net asset value was determined.

For the month and year in which this Agreement becomes effective or terminates, there shall be an appropriate proration on the basis of the number of days that the Agreement is in effect during the month and year, respectively.

7. Services to Others. The Adviser understands, and has advised the Fund’s Board of Trustees, that the Sub-Adviser now acts, and may in the future act, as an investment adviser to other investment portfolios, including investment companies, provided that whenever the Fund and one or more other investment advisory clients of the Sub-Adviser have available funds for investment, investments suitable and appropriate for each will be allocated in a manner believed by the Sub-Adviser to be equitable to each. The Adviser recognizes, and has advised the Fund’s Board of Trustees, that in some cases this procedure may adversely affect the size of the position that the Fund may obtain in a particular security. It is further agreed that, on occasions when the Sub-Adviser deems the purchase or sale of a security to be in the best interests of the Fund as well as other accounts, it may, to the extent permitted by applicable law, but will not be obligated to, aggregate the securities to be so sold or purchased for the Fund with those to be sold or

purchased for other accounts in order to obtain favorable execution and lower brokerage commissions. In addition, the Adviser understands, and has advised the Fund’s Board of Trustees, that the persons employed by the Sub-Adviser to assist in the Sub-Adviser’s duties under this Agreement will not devote their full such efforts and service to the Fund. It is also agreed that the Sub-Adviser may use any supplemental research obtained for the benefit of the Fund in providing investment advice to its other investment advisory accounts or for managing its own accounts. The Sub-Adviser shall be subject to a written code of ethics adopted by it pursuant to Rule 17j-1 of the 1940 Act, and shall not be subject to any other code of ethics, including the Adviser’s code of ethics, unless specifically adopted by the Sub-Adviser.

8. Limitation of Liability. The Sub-Adviser shall not be liable for, and the Adviser will not take any action against the Sub-Adviser to hold the Sub-Adviser liable for, any error of judgment or mistake of law or for any loss suffered by the Fund (including, without limitation, by reason of the purchase, sale or retention of any security) in connection with the performance of the Sub-Adviser’s duties under this Agreement, except for a loss resulting from willful misfeasance, bad faith or gross negligence on the part of the Sub-Adviser in the performance of its duties under this Agreement, or by reason of its reckless disregard of its obligations and duties under this Agreement.

This Agreement shall continue in force from year to year thereafter with respect to the Fund, but only as long as such continuance is specifically approved for the Fund at least annually in the manner required by the 1940 Act and the rules and regulations thereunder; provided, however, that if the continuation of this Agreement is not approved for the Fund, the Sub-Adviser may continue to serve in such capacity for the Fund in the manner and to the extent permitted by the 1940 Act and the rules and regulations thereunder.

This Agreement shall automatically terminate in the event of its assignment and may be terminated at any time without the payment of any penalty by the Adviser on no less than sixty (60) days’ written notice to the Sub-Adviser. This Agreement may be terminated at any time without the payment of any penalty by the Sub-Adviser on no less than sixty (60) days’ written notice to the Adviser. This Agreement may also be terminated by the Fund by action of the Board of Trustees or by a vote of a majority of the outstanding voting securities of the Fund on no less than sixty (60) days’ written notice to the Sub-Adviser by the Fund.

This Agreement may be terminated with respect to the Fund at any time without the payment of any penalty by the Adviser or the Board of Trustees or by vote of a majority of the outstanding voting securities of the Fund in the event that it shall have been established by a court of competent jurisdiction that the Sub-Adviser or any officer or director of the Sub-Adviser has taken any action that results in a breach of the representations of the Sub-Adviser set forth herein.

This Agreement shall automatically terminate in the event the Management Agreement between the Adviser and the Fund is terminated, assigned or not renewed.

10. Notice. All notices provided for by this Agreement shall be in writing and shall be deemed given when received, against appropriate receipt, by the General Counsel of the Adviser or Sub-Adviser, as the case may be, or such other person as a party shall designate by notice to the other parties.
