WHEREAS, the Adviser and the Sub-Adviser are registered as investment advisers under the Investment Advisers Act of 1940, as amended (the “Advisers Act”); and

WHEREAS, the Adviser and the Corporation have entered into an investment advisory agreement (the “Investment Advisory Agreement”), pursuant to which the Adviser serves as investment manager of the Fund and may delegate certain investment management duties to one or more sub-adviser(s); and

WHEREAS, the Adviser, with the approval of the Board of Directors of the Corporation (the “Board”), including a majority of the Directors who are not “interested persons” (defined herein) of any party to this Agreement, desires to delegate to the Sub-Adviser the duty to manage a portion of the assets of the Fund as designated by the Adviser from time to time (the “Segment”);

NOW, THEREFORE, in consideration of the promises and mutual covenants herein contained, it is agreed among the parties hereto as follows:

1. Appointment of Sub-Adviser. The Adviser hereby appoints the Sub-Adviser and the Sub-Adviser hereby agrees to provide the services described in Section 2 below for investment and reinvestment of the securities and other assets of the Segment for the period and on the terms hereinafter set forth, subject to the terms of this Agreement and subject to the direction, control and supervision of the Adviser and the Board.

2. Services of Sub-Adviser.

(a) The Sub-Adviser shall perform the following services on behalf of the Fund:

(i) provide investment advisory services, including but not limited to portfolio securities selection, research, advice and supervision for the Segment;

(ii) manage the investment and reinvestment of all assets, now or hereafter a part of the Segment, including placing orders for the purchase and sale of securities and other assets in its discretion and without prior consultation with the Adviser, subject, in all cases, to (A) the Fund’s investment objective, strategies, and restrictions as stated in the Fund’s prospectus and statement of additional information, as both may be amended from time to time, hereinafter referred to as the “Approved Investment Program,” and (B) the provisions of the 1940 Act and rules and regulations thereunder;

(iii) instruct the Fund’s custodian to deliver for cash received securities or other cash and/or securities instruments sold, exchanged, redeemed or otherwise disposed of from the Segment, and to pay cash for securities or other cash and/or securities instruments delivered to the custodian and/or credited to the Segment upon acquisition of the same for the Segment;

(iv) report on the activities in the performance of its duties and obligations under this Agreement to the Board at such times and in such detail as the Board may reasonably request, and keep the Board and the Adviser informed of important developments affecting the Segment, and on its own initiative furnish the Adviser and the Board from time-to-time with such information as the Sub-Adviser may believe appropriate, whether concerning the individual companies whose securities are held in the Segment, the industries in which they engage, or the economic, social or political conditions prevailing in each country in which the Segment maintains investments;

(v) furnish, at its own expense, (A) all necessary investment and management facilities, including compensation of personnel required for it to execute its duties hereunder, and (B) administrative facilities, including bookkeeping, clerical personnel and equipment necessary for the efficient conduct of the investment management and administration of the Segment; and

(vi) provide upon reasonable request assistance and recommendations for the determination of the fair value of certain securities held as part of the Segment when reliable market quotations are not readily available for purposes of calculating net asset value in accordance with procedures and methods established by the Board.

2

(b) In connection with the performance of its services hereunder, the Sub-Adviser shall:

(i) open accounts with broker-dealers (collectively, “Broker-Dealers”), select Broker-Dealers to effect all transactions for the Segment, place all necessary orders with Broker-Dealers or issuers, and negotiate commissions, if applicable;

(ii) aggregate purchase or sell orders for the Segment with contemporaneous purchase or sell orders of its other clients to the extent consistent with applicable law and the Approved Investment Program; provided that in such event, allocation of securities so sold or purchased, as well as the expenses incurred in the transaction, will be made by the Sub-Adviser in the manner the Sub-Adviser considers to be the most equitable, and consistent with applicable law and regulations and its fiduciary obligations to the Fund; and

(iii) obtain best execution of transactions for the Segment at prices which are advantageous to the Segment and at commission rates that are reasonable in relation to the benefits received.

To the extent consistent with Section 28(e) of the Securities Exchange Act of 1934, the Sub-Adviser may pay a Broker-Dealer an amount of commission for effecting a securities transaction in excess of the amount of commission another Broker-Dealer would have charged for effecting such transaction if the Sub-Adviser determines in good faith that such amount of commission is reasonable in relation to the value of the brokerage and research products and/or services provided by such Broker-Dealer. This determination, with respect to brokerage and research products and/or services, may be viewed in terms of either that particular transaction or the overall responsibilities which the Sub-Adviser has with respect to the Segment, as well as to other accounts over which the Sub-Adviser exercises investment discretion.

(c) With respect to any investments for the Fund that are permitted to be made by the Sub-Adviser in accordance with this Agreement and the Approved Investment Program, the Sub-Adviser shall do and perform every act and thing it deems to be necessary or incidental in performing its duties and obligations under this Agreement including, but not limited to, executing as agent on behalf of the Fund, as the case may be, such agreements and other documentation as may be required for the purchase or sale, assignment, transfer and ownership of any investment permitted pursuant to the Approved Investment Program, including, but not limited to, limited partnership agreements, future and option contracts, loan assignments and acceptances, repurchase and derivatives agreements, including any schedules and annexes to such agreements, releases, consents, elections and confirmations. The Corporation will provide the Sub-Adviser with tax information, governing documents, legal opinions and other information concerning the Corporation necessary to complete trading account agreements and other documentation.

5

5. Confidentiality of Information. (a) None of the Adviser, the Fund, or the Sub-Adviser shall disclose information of a confidential nature acquired in connection with this Agreement, including any non-public information about shareholders of the Fund or the Fund, except for information that they may be entitled or bound to disclose by law, regulation or court order, or which is disclosed to their advisers where reasonably necessary for the performance of their professional services. The Sub-Adviser shall also comply with the Fund’s policies with respect to disclosure of portfolio holdings.

(b) Notwithstanding the provisions of Section 5(a), to the extent that any Broker-Dealer or counterparty with whom the Sub-Adviser deals on behalf of the Segment requires information relating to the Fund or Segment (including, but not limited to, the identity of the Adviser or the Fund and market value of the Fund or Segment), the Sub-Adviser shall be permitted to disclose such information to the extent necessary to effect transactions on behalf of the Segment in accordance with the terms of this Agreement.

As full compensation for all services rendered and obligations assumed by the Sub-Adviser hereunder with respect to the Segment, the Adviser shall pay the compensation specified in Appendix A to this Agreement. The Sub-Adviser acknowledges and agrees that the Adviser shall be solely responsible for the fees of the Sub-Adviser for its services hereunder, and the Sub-Adviser shall have no claim against the Corporation or the Fund with respect to its compensation under this Agreement.

7. Standard of Care and Liability of Sub-Adviser. (a) The Sub-Adviser shall exercise its best judgment and efforts in rendering the services under this Agreement. The Sub-Adviser shall not be liable for any losses suffered by the Fund resulting from any error of judgment or mistake of law in connection with the performance of its duties under this Agreement, except for losses resulting from a breach of fiduciary duty or from willful misfeasance, bad faith, negligence or reckless disregard of obligations and duties hereunder of the Sub-Adviser or any of its officers, directors, members, employees, agents or affiliates, or from any violations of securities or any other applicable laws, rules, regulations, statues and codes, whether federal or state, by the Sub-Adviser or any of its officers, directors, members, employees, agents or affiliates.

(b) In no event will the Sub-Adviser have any responsibility for any portion of the Fund other than the Segment, or for the acts or omissions of the Adviser or any other sub-adviser to the Fund. In particular, the Sub-Adviser shall have no responsibility for the Fund’s being in violation of any applicable law or regulation or investment policy or restriction applicable to the Fund as a whole or for the Fund’s failing to qualify as a regulated investment company under the Code, if the securities and other holdings of the Segment managed by the Sub-Adviser are such that the Segment would not be in such violation or fail to so qualify if the Segment were deemed a separate series of the Corporation or a separate “regulated investment company” under the Code. The Sub-Adviser shall take all necessary steps to ensure the Fund’s ongoing compliance with the Code, any applicable law or regulation or investment policy or restriction applicable to the

6

Fund. Nothing in this Section 7 shall be deemed a limitation or waiver of any obligation or duty that may not by law be limited or waived.

8. Indemnification. The Sub-Adviser shall indemnify and hold harmless the Fund, the Corporation, and the Adviser from and against any and all direct or indirect claims, losses, liabilities or damages (including reasonable attorneys’ fees and other related expenses) resulting from a breach of fiduciary duty, from willful misfeasance, bad faith or gross negligence on the part of the Sub-Adviser or any of its officers, directors, members, employees, agents or affiliates in connection with the performance of their duties under this Agreement, from reckless disregard by it or its officers, directors, members, employees, agents or affiliates of any of their obligations and duties under this Agreement, or from any violations of securities laws, rules, regulations, statues and codes, whether federal or state, by the Sub-Adviser or any of its officers, directors, members, employees, agents or affiliates; provided, however, that the Sub-Adviser shall not be required to indemnify or otherwise hold the Fund or the Adviser harmless under this Section 8 where the claim against, or the loss, liability, or damage experienced by the Fund or the Adviser, is caused by or is otherwise directly related to the willful misfeasance, bad faith or gross negligence of the Fund, the Adviser, or their respective officers, directors, members, or employees or to the reckless disregard by the Fund, the Adviser, or their respective officers, directors, members, or employees of their duties under this Agreement.

APPENDIX A

SUB-ADVISORY FEES

The Adviser will pay the Sub-Adviser, as full compensation for all services provided under this Agreement, an annual fee computed at the following annual rates based on the Segment’s average daily net assets:

The Sub-Adviser’s fee shall be accrued for each calendar day and the sum of the daily fee accruals shall be paid monthly in arrears to the Sub-Adviser on or before the tenth business day of the next succeeding calendar month. The daily fee accruals will be computed by multiplying the fraction of one over the number of calendar days in the year by the applicable annual rate set forth in the schedule above and multiplying this product by the net assets of the Segment, as determined in accordance with the Fund’s prospectus and statement of additional information as of the close of business on the previous business day on which the Fund was open for business. For each monthly fee payment, the Adviser will provide the Sub-Adviser with a worksheet accompanying payment of the sub-advisory fee that sets forth the computation of such sub-advisory fee.

If this Agreement becomes effective or terminates before the end of any month, the sub-advisory fee (if any) for the period from such effective date to the end of such month or from the beginning of such month to the date of such termination, as the case may be, shall be prorated according to the proportion which such period bears to the full month in which such effectiveness or termination occurs.
