U.S. CORE FUND

SUB-ADVISORY AGREEMENT

Sub-Advisory Agreement (the “Agreement”) executed as of September 21, 2005 between JOHN HANCOCK INVESTMENT MANAGEMENT SERVICES, LLC, a Delaware limited liability company (the “Adviser”), and GRANTHAM, MAYO, VAN OTTERLOO & CO. LLC, a Massachusetts limited liability company (the “Subadviser”).

WHEREAS, the Adviser serves as investment adviser of the U.S. Core Fund (the “Fund”), a series of John Hancock Funds III (the “Trust”), a Massachusetts business trust which has filed a registration statement under the Investment Company Act of 1940, as amended (the “1940 Act”) and the Securities Act of 1933 (the “1933 Act”); and

WHEREAS, the Trust consists of several series, one of which is the Fund; and

WHEREAS, the Adviser is registered under the Investment Advisers Act of 1940, as amended (the “Advisers Act”), and desires to avail itself of the services, advice and assistance of the Subadviser to assist the Adviser in providing investment advisory services to the Fund; and

WHEREAS, the Subadviser is registered under the Advisers Act, and is engaged in the business of rendering investment advisory services to investment companies and other institutional clients and desires to provide such services to the Adviser;

NOW, THEREFORE, in consideration of the mutual covenants herein contained, it is agreed as follows:

1. SERVICES TO BE RENDERED BY THE SUBADVISER

(a) Subject always to the control of the trustees of the Trust (the “Trustees”), the Subadviser, at its expense, will furnish continuously an investment program for the Fund and will make investment decisions on behalf of the Fund and place all orders for the purchase and sale of portfolio securities and all other investments. The Subadviser will allocate all facilities and personnel necessary for the conduct of its duties under this Agreement. In the performance of its duties, the Subadviser will comply with (1) the provisions of the Trust’s Agreement and Declaration of Trust and By-laws, and the investment objectives, policies and restrictions of the Fund as set forth in its current Prospectus and Statement of Additional Information (copies of which will be supplied to the Subadviser upon filing with the SEC), and any amendments to such Agreement and Declaration of Trust, By-laws, investment objectives, policies and restrictions which the Trustees or the Adviser, as the case may be, may from time to time determine, as promptly as practicable after such amendments have been communicated to the Subadviser in writing, and (2) other policies which the Trustees may from time to time determine, as promptly as practicable after such policies have been communicated to the Subadviser in writing. The Subadviser and the Adviser shall each make its officers and employees and any information reasonably requested available to the other from time to time at reasonable times to review investment policies of the Fund, to facilitate the Adviser’s monitoring of the Subadviser, and to consult with each other regarding the investment affairs of the Fund.

(b) The Subadviser shall bear its own expenses in providing services pursuant to this Agreement, including salaries of its personnel. The Subadviser shall not be obligated to pay any expenses of the Adviser, the Trust or the Fund, including without limitation (i) interest and taxes; (ii) brokerage commissions and other costs in connection with the purchase and sale of securities and other investment instruments of the Fund; and (iii) custodian fees and expenses. The Subadviser shall not be obligated to pay any expenses of or for the Fund not expressly assumed by the Subadviser pursuant to this Section 1. Any reimbursement of management or other fees required by an expense limitation or waiver provision, and any liability arising out of a violation by the Adviser of Section 36(b) of the 1940 Act, shall be the sole responsibility of the Adviser, provided that nothing herein shall relieve the Subadviser from its own liability under Section 36(b) of the 1940 Act with respect to its duties under this Agreement.

(c) In the selection of brokers or dealers and the placing of orders for the purchase and sale of portfolio investments for the Fund, the Subadviser shall use its best efforts to obtain for the Fund the most favorable price and execution available, except to the extent it may be permitted to pay higher brokerage commissions for brokerage and research services as described below. In using its best efforts to obtain for the Fund the most favorable price and execution available, the Subadviser, bearing in mind the Fund’s best interests at all times, shall consider all factors it deems relevant, including, by way of illustration, price, the size of the transaction, the nature of the market for the security, the amount of the commission, the timing of the transaction taking into account market prices and trends, the execution capability, reputation, experience and financial stability of the broker or dealer involved and the quality of service rendered by the broker or dealer in other transactions. Subject to such policies as the Trustees of the Trust may determine and communicate to the Subadviser in writing, the Subadviser 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 or dealer that provides brokerage and research services to the Subadviser or its affiliates an amount of commission for effecting a portfolio investment transaction in excess of the amount of commission another broker or dealer would have charged for effecting that transaction, if the Subadviser determines in good faith that such amount of commission was reasonable in relation to the value of the brokerage and research services provided by such broker or dealer, viewed in terms of either that particular transaction or the Subadviser’s overall responsibilities with respect to the Fund and to other clients of the Subadviser and its affiliates as to which the Subadviser or its affiliates exercise investment discretion.

(d) The Subadviser may execute Fund documentation, agreements, contracts and other documents requested by brokers, dealers, counterparties and other persons in connection with its providing investment advisory services to the Fund.

(e) Nothing herein shall be considered as constituting the Subadviser as an agent for the Adviser or the Fund or the Trust or as anything other than an independent contractor with respect to the Adviser or the Fund or the Trust.

(f) The Subadviser makes no representation or warranty, express or implied, that any level of performance or investment results will be achieved by the Fund or that the Fund will perform comparably with any standard, including other funds managed by the Subadviser.

-2-

(g) The Subadviser will provide such access to the Subadviser’s chief compliance officer and such compliance-related information concerning the Subadviser’s services to the Fund under this Agreement as may reasonably be requested by the chief compliance officer of the Adviser or of the Fund, as the case may be.

2. OTHER AGREEMENTS, ETC.

It is understood that any of the shareholders, Trustees, officers and employees of the Trust may be a shareholder, member, director, officer or employee of, or be otherwise interested in, the Subadviser, and in any person controlled by or under common control with the Subadviser, and that the Subadviser and any person controlled by or under common control with the Subadviser may have an interest in the Trust. It is also understood that this is a non-exclusive contract for services, and that the Subadviser and persons controlled by or under common control with the Subadviser have and may have advisory, management service or other contracts with other organizations and persons, and may have other interests and businesses. The Subadviser may, by way of example and not by way of limitation, undertake to act as investment adviser or subadviser for any investment company, including without limitation other U.S. registered investment companies with identical investment policies to the Fund. Nothing in this paragraph is intended to negate or otherwise limit any existing or future agreements between the Adviser and the Subadviser beyond this Agreement that may have the effect of limiting (i) the organizations and persons to which the Subadviser may provide investment advisory services or (ii) the nature of the investment advisory services the Subadviser may provide to other organizations and persons.

3. COMPENSATION TO BE PAID BY THE MANAGER TO THE SUBADVISER

The Adviser will pay to the Subadviser the compensation specified in Appendix A in return for the Subadviser’s services rendered hereunder.
