NOW, THEREFORE, in consideration of the premises and the covenants hereinafter contained, the Fund, the Investment Manager and the Sub-Investment Manager hereby agree as follows:

ARTICLE 1.

Duties of the Sub-Investment Manager

Subject to the supervision and approval of the Investment Manager and the Fund’s Board of Directors, the Sub-Investment Manager will manage the investment and reinvestment of the assets of the Fund’s MetLife MSCI EAFE Index Portfolio (the “Portfolio”) for the period and on the terms and conditions set forth in this Agreement. In acting as Sub-Investment Manager to the Fund with respect to the Portfolio, the Sub-Investment Manager shall determine which securities

shall be purchased, sold or exchanged and what portion of the assets of the Portfolio shall be held in the various securities or other assets in which it may invest, subject always to any restrictions of the Fund’s Declaration of Trust and By-Laws, as amended or supplemented from time to time, the provisions of applicable laws and regulations including the Investment Company Act, and the statements relating to the Portfolio’s investment objectives, policies and restrictions as the same are set forth in the prospectus and statement of additional information of the Fund then currently effective under the Securities Act of 1933 (the “Prospectus”). Should the Board of Directors of the Fund or the Investment Manager at any time, however, make any definite determination as to investment policy and notify in writing the Sub-Investment Manager thereof, the Sub-Investment Manager shall be bound by such determination for the period, if any, specified in such notice or until similarly notified in writing that such determination has been revoked. The Sub-Investment Manager shall take, on behalf of the Fund, all actions which it deems necessary to implement the investment policies of the Portfolio, determined as provided above, and in particular to place all orders for the purchase or sale of portfolio securities for the Portfolio with brokers or dealers selected by it.

In connection with the selection of such brokers or dealers and the placing of such orders, the Sub-Investment Manager is directed at all times to follow the policies of the Fund set forth in the Prospectus. Nothing herein shall preclude the “bunching” of orders for the sale or purchase of portfolio securities with other Fund portfolios or with other accounts managed by the Sub-Investment Manager. The Sub-Investment Manager shall not favor any account over any other and any purchase or sale orders executed contemporaneously shall be allocated in a manner it deems equitable among the accounts involved and at a price which is approximately averaged.

In connection with these services the Sub-Investment Manager will provide investment research as to the Portfolio’s investments and conduct a continuous program of evaluation of its assets. The Sub-Investment Manager will have the responsibility to monitor the investments of the Portfolio to the extent necessary for the Sub-Investment Manager to manage the Portfolio in a manner that is consistent with the investment objective and policies of the Portfolio set forth in the Prospectus, as from time to time amended, and communicated in writing to the Sub-Investment Manager, and consistent with applicable law, including, but not limited to, the Investment Company Act and the rules and regulations thereunder and the applicable provisions of the Internal Revenue Code and the rules and regulations thereunder (including, without limitation, subchapter M of the Code and the investment diversification aspects of Section 817(h) of the Code).

The Sub-Investment Manager will furnish the Investment Manager and the Fund such statistical information, including prices of securities in situations where a fair valuation determination is required or when a security cannot be priced by the Fund’s accountants, including prices of securities in situations where a fair valuation determination is required or when a security cannot be priced by the Fund’s accountants, with respect to the investments it makes for the Portfolio as the Investment Manager and the Fund may reasonably request. On its own initiative, the Sub-Investment Manager will apprise the Investment Manager and the Fund of important developments materially affecting the Portfolio, including but not limited to any change in the personnel of the Sub-Investment Manager responsible for the day to day investment decisions made by the Sub-Investment Manager for the Portfolio and any material legal proceedings against the Sub-Investment Manager by the Securities and Exchange Commission relating to

2

violations of the federal securities laws by the Sub-Investment Manager, and will furnish the Investment Manager and the Fund from time to time with similar material information that is believed appropriate for this purpose. In addition, the Sub-Investment Manager will furnish the Investment Manager and the Fund’s Board of Directors such periodic and special reports as either of them may reasonably request.

The Sub-Investment Manager will exercise its best judgment in rendering the services provided for in this Article 1, and the Fund and the Investment Manager agree, as an inducement to the Sub-Investment Manager’s undertaking so to do, that the Sub-Investment Manager will not be liable under this Agreement for any mistake of judgment or in any other event whatsoever, except as hereinafter provided. The Sub-Investment Manager shall for all purposes herein be deemed to be an independent contractor and shall, unless otherwise provided or authorized, have no authority to act for or represent the Fund or the Investment Manager in any way or otherwise be deemed an agent of the Fund or the Investment Manager other than in furtherance of its duties and responsibilities as set forth in this Agreement.

Notwithstanding any other provision of this Agreement, the Fund, the Investment Manager and the Sub-Investment Manager may agree to the employment of a Sub-Sub-Investment Manager to the Fund for the purpose of providing investment management services with respect to the Portfolio, provided that the compensation to be paid to such Sub-Sub-Investment Manager shall be the sole responsibility of the Sub-Investment Manager and the duties and responsibilities of the Sub-Sub-Investment Manager shall be as set forth in a sub-sub-investment management agreement among the Investment Manager, the Sub-Investment Manager, the Sub-Sub-Investment Manager and the Fund on behalf of the Portfolio.

ARTICLE 2.

Sub-Investment Management Fee

The payment of advisory fees and the allocation of charges and expenses between the Fund and the Investment Manager with respect to the Portfolio are set forth in the MetLife MSCI EAFE Index Portfolio Investment Management Agreement. Nothing in this MetLife MSCI EAFE Index Portfolio Sub-Investment Management Agreement shall change or affect that arrangement. The payment of advisory fees and the apportionment of any expenses related to the services of the Sub-Investment Manager under this Agreement shall be the sole concern of the Investment Manager and the Sub-Investment Manager and shall not be the responsibility of the Fund.

In consideration of services rendered pursuant to this Agreement, the Investment Manager will pay the Sub-Investment Manager on the first business day of each month the fee at the annual rate specified by the schedule of fees in the Appendix to this Agreement. The fee for any period from the date the Portfolio commences operations to the end of the month will be prorated according to the proportion which the period bears to the full month, and, upon any termination of this Agreement before the end of any month, the fee for the part of the month during which the Sub-Investment Manager acted under this Agreement will be prorated according to the proportion which the period bears to the full month and will be payable upon the date of termination of this Agreement.

For the purpose of determining the fees payable to the Sub-Investment Manager, the value of the

3

Portfolio’s net assets will be computed in the manner specified in the Fund’s Prospectus. The Sub-Investment Manager will bear all of its own expenses (such as research costs) in connection with the performance of its duties under this Agreement except for those which the Investment Manager agrees to pay.

The Sub-Investment Manager agrees to notify promptly, upon written request, the Investment Manager if, for any other registered investment company having a substantially similar investment program, it agrees to (1) provide more services or bear more expenses for a comparable or lower fee; and (2) provide comparable services and bear comparable expenses for a lower fee.

Other Matters.

The Sub-Investment Manager may from time to time employ or associate with itself any person or persons believed to be particularly fitted to assist in its performance of services under this Agreement. The compensation of any such persons will be paid by the Sub-Investment Manager, and no obligation will be incurred by, or on behalf of, the Fund or the Investment Manager with respect to them.

The Fund and the Investment Manager understand that the Sub-Investment Manager now acts and will continue to act as investment manager to various investment companies and fiduciary or other managed accounts, and the Fund and the Investment Manager have no objection to the Sub-Investment Manager’s so acting. In addition, the Fund understands that the persons employed by the Sub-Investment Manager to assist in the performance of the Sub-Investment Manager’s duties hereunder will not devote their full time to such service, and nothing herein contained shall be deemed to limit or restrict the Sub-Investment Manager’s right or the right of any of the Sub-Investment Manager’s affiliates to engage in and devote time and attention to other businesses or to render other services of whatever kind or nature.

The Sub-Investment Manager agrees that all books and records which it maintains for the Fund are the Fund’s property. The Sub-Investment Manager also agrees upon request of the Investment Manager or the Fund, promptly to surrender the books and records to the requester or make the books and records available for inspection by representatives of regulatory authorities. The Sub-Investment Manager further agrees to maintain and preserve the Fund’s books and records in accordance with the Investment Company Act and rules thereunder.

The Sub-Investment Manager will not be liable for any error of judgment or mistake of law or for any loss suffered by the Fund in connection with the matters to which this Agreement relates, except for a loss resulting from willful misfeasance, bad faith or gross negligence of the Sub-Investment Manager in the performance of its duties or from reckless disregard of its obligations and duties under this Agreement.

The Investment Manager has herewith furnished the Sub-Investment Manager copies of the Fund’s Prospectus, Declaration of Trust and By-Laws as currently in effect and agrees during the continuance of this Agreement to furnish the Sub-Investment Manager copies of any amendments or supplements thereto before or at the time the amendments or supplements become effective. The Sub-Investment Manager will be entitled to rely on all documents furnished to it by the Investment Manager or the Fund.
