EX-99.D 6 gmoadvagmtaddendum.txt GRANTHAM MAYO VAN OTTERLOO & CO INV AGMT VANGUARD EXPLORER FUND INVESTMENT ADVISORY AGREEMENT ADDENDUM Effective January 31, 2003 This Addendum amends Section 4 of the Investment Advisory Agreement dated April 3, 2000 between Vanguard EXPLORER FUND (the "Fund") and GRANTHAM, MAYO, VAN OTTERLOO & CO. LLC ("GMO") as follows. 4. COMPENSATION OF GMO. For the services to be rendered by GMO as provided in this Agreement, the Fund will pay to GMO at the end of each of the Fund's fiscal quarters, a Basic Fee calculated by applying a quarterly rate, based on the following annual percentage rates, to the average month-end net assets of the GMO Portfolio for the quarter: .275% on the first $500 million of net assets; .225% on the next $500 million of net assets; .200% on net assets in excess of $1 billion. Subject to the Transition Rule described in Section 4.1, the Basic Fee, as provided above, will be increased or decreased by applying a Performance Fee Adjustment (the "Adjustment") based on the investment performance of the GMO Portfolio relative to the investment performance of the Russell 2500 Growth Index. The investment performance of the GMO Portfolio will be based on the cumulative return over a trailing 36-month period ending with the applicable quarter, relative to the cumulative total return of the Russell 2500 Growth Index for the same time period. The Adjustment applies as follows: Cumulative 36-Month Performance of the GMO Adjustment as a Percentage Portfolio vs. the Russell 2500 Growth Index of Average Net Assets* ------------------------------------------- ---------------------- Trails by any amount -0.15% Equals or exceeds by up to 3% Linear increase from -0.15% to 0% Exceeds by 3% to 6% Linear increase from 0% to +0.15% Exceeds by more than 6% +0.15% ------------------ * For purposes of this calculation, the average net assets will be calculated as average month-end net assets over the 36-month period. 4.1.
