THIS AGREEMENT is made as of this 24th day of July, 2006, between Vanguard Model Fund, a Delaware statutory trust (the “Trust”), and ABC Asset Management LLC (the “Advisor”), a Delaware limited liability company.

W I T N E S S E T H

WHEREAS, the Trust is an open-end, diversified management investment company registered under the Investment Company Act of 1940, as amended (the “1940 Act”); and

WHEREAS, the Trust offers a series of shares known as Vanguard XYZ Fund (the “Fund”); and

WHEREAS, the Trust desires to retain the Advisor to render investment advisory services to the Fund, and the Advisor is willing to render such services.

NOW THEREFORE, in consideration of the mutual promises and undertakings set forth in this “Agreement,” the Trust and the Advisor hereby agree as follows:

1. Appointment of Advisor. The Trust hereby employs the Advisor as investment advisor, on the terms and conditions set forth herein, for the portion of the assets of the Fund that the Trust’s Board of Trustees (the “Board of Trustees”) determines in its sole discretion to assign to the Advisor from time to time (referred to in this Agreement as the “ABC Portfolio”), as communicated to the Advisor on behalf of the Board of Trustees by The Vanguard Group, Inc. (“Vanguard”). The Board of Trustees may, from time to time, make additions to, and withdrawals from, the assets of the Fund assigned to the Advisor. The Advisor accepts such employment and agrees to render the services herein set forth, for the compensation herein provided.

2. Duties of Advisor. The Trust employs the Advisor to manage the investment and reinvestment of the assets of the ABC Portfolio; to continuously review, supervise, and administer an investment program for the ABC Portfolio; to determine in its discretion the securities to be purchased or sold and the portion of such assets to be held uninvested; to provide the Fund with all records concerning the activities of the Advisor that the Fund is required to maintain; and to render regular reports to the Trust’s officers and the Board of Trustees concerning the discharge of the foregoing responsibilities. The Advisor will discharge the foregoing responsibilities subject to the supervision and oversight of the Trust’s officers and the Board of Trustees, and in compliance with the objective, policies, and limitations set forth in the Fund’s prospectus and Statement of Additional Information, any additional operating policies or procedures that the Fund communicates to the Advisor in writing, and applicable laws and regulations. The Advisor agrees to provide, at its own expense, the office space, furnishings and equipment, and personnel required by it to perform the services on the terms and for the compensation provided herein.

3. Securities Transactions. The Advisor is authorized to select the brokers or dealers that will execute purchases and sales of securities for the ABC Portfolio, and is directed to seek to obtain best execution for such transactions, consistent with Section 28(e) of the Securities Exchange Act of 1934. In selecting brokers or dealers to execute trades for the ABC Portfolio, the Advisor will comply with all applicable statutes, rules, interpretations by the U.S. Securities and Exchange Commission or its staff, other applicable law, and the written policies and procedures established by the Board of Trustees and communicated to the Advisor in writing.

4. Compensation of Advisor. For services to be provided by the Advisor pursuant to this Agreement, the Fund will pay to the Advisor, and the Advisor agrees to accept as full compensation therefor, an investment advisory fee consisting of a base fee plus a performance adjustment at the rates specified in Schedule A to this agreement, payable quarterly in arrears.

5. Reports. The Fund and the Advisor agree to furnish to each other current prospectuses, proxy statements, reports to shareholders, certified copies of their financial statements, and such other information with regard to their affairs as each may reasonably request, including, but not limited to, information about changes in investment officers of the Advisor who are responsible for managing the ABC Portfolio.

6. Compliance. The Advisor agrees to comply with all Applicable Law and all policies, procedures or reporting requirements that the Board of Trustees reasonably adopts and communicates to the Advisor in writing, including, without limitation, any such policies, procedures, or reporting requirements relating to soft dollar or other brokerage arrangements. “Applicable Law” means (i) the “federal securities laws” as defined in Rule 38a-1(e)(1) under the 1940 Act, as amended from time to time, and (ii) any and all other laws, rules, and regulations, whether foreign or domestic, in each case applicable at any time and from time to time to the investment management operations of the Advisor in relation to the ABC Portfolio.

7. Status of Advisor. The services of the Advisor to the Fund are not to be deemed exclusive, and the Advisor will be free to render similar services to others so long as its services to the Fund are not impaired thereby. The Advisor will be deemed to be an independent contractor and will, unless otherwise expressly provided or authorized, have no authority to act for or represent the Fund in any way or otherwise be deemed an agent of the Fund or the Trust.

8. Liability of Advisor. No provision of this Agreement will be deemed to protect the Advisor against any liability to the Fund or its shareholders to which it might otherwise be subject by reason of any willful misfeasance, bad faith, or negligence in the performance of its duties or the reckless disregard of its obligations under this Agreement.

9. Limitations on Consultations. The Advisor is prohibited from consulting with other advisors of the Fund, except Vanguard, concerning transactions for the Fund in securities or other assets.

10. Duration; Termination; Notices; Amendment. This Agreement will become effective on the date hereof and will continue in effect for a period of two years thereafter, and shall continue in effect for successive twelve-month periods thereafter, only so long as each such continuance specifically is approved at least annually by the Board of Trustees, including a majority of those Trustees who are not parties to such Agreement or interested persons of any such party, cast in person at a meeting called for the purpose of voting on such approval. In addition, the question of continuance of the Agreement may be presented to the shareholders of the Fund; in such event, such continuance will be effected only if approved by the affirmative vote of a majority of the outstanding voting securities of the Fund.

Notwithstanding the foregoing, however, (i) this Agreement may at any time be terminated without payment of any penalty either by vote of the Board of Trustees or by vote of a majority of the outstanding voting securities of the Fund, on thirty days’ written notice to the Advisor, (ii) this Agreement will automatically terminate in the event of its assignment, and (iii) this Agreement may be terminated by the Advisor on ninety days’ written notice to the Fund. Any notice under this Agreement will be given in writing, addressed and delivered, or mailed postpaid, to the other party as follows:
