AMENDED AND RESTATED FEE WAIVER AND

EXPENSE ASSUMPTION AGREEMENT

AMENDED AND RESTATED AGREEMENT made this ___ day of March, 2007 and effective March 30, 2007, between Dimensional Investment Group Inc., a Maryland corporation (the “Fund”), on behalf of certain portfolios of the Fund, as listed on Schedule A of this Agreement (each a “Portfolio,” and together, the “Portfolios”), and Dimensional Fund Advisors LP, a Delaware limited partnership (“DFA”) (formerly Dimensional Fund Advisors Inc.), amending and restating the Amended and Restated Fee Waiver and Expense Assumption Agreement dated December 23, 2003.

WHEREAS, DFA has entered into Administration Agreements with the Fund, pursuant to which DFA provides various administrative and other services for the Portfolios, and for which DFA is compensated based on the average net assets of such Portfolios; and

WHEREAS, the Fund and DFA have determined that it is appropriate and in the best interests of each Portfolio and its shareholders to limit the expenses of those Portfolios, and those classes of certain Portfolios, of the Fund listed on Schedule A of this Agreement;

NOW, THEREFORE, the parties hereto agree as follows:

1. Fee Waiver and Expense Assumption by DFA. DFA agrees to reduce all or a portion of its administration fee for Portfolio, or each class of a Portfolio, as applicable, listed on Schedule A, and if necessary (for each Portfolio other than the Emerging Markets Portfolio II), to assume certain other expenses (to the extent permitted by the Internal Revenue Code of 1986, as amended) of each such Portfolio (or class of a Portfolio), such fee waiver and assumption of expenses as detailed on Schedule A of this Agreement, to the extent necessary to limit the annualized expenses of each Portfolio (or class of a Portfolio) to the rate reflected in Schedule A of this Agreement for each Portfolio (or class of a Portfolio) (“Annualized Expense Ratio”).

2. Duty to Reimburse DFA. If, at any time, the annualized expenses of a Portfolio (or class of a Portfolio) are less than the Annualized Expense Ratio listed on Schedule A of this Agreement, the Fund, on behalf of a Portfolio (except for Emerging Markets Portfolio II), shall reimburse DFA for any fees previously waived and/or expenses previously assumed to the extent that the amount of such reimbursement does not cause the Annualized Expense Ratio of a Portfolio (or class of a Portfolio) to exceed the limit on Schedule A of this Agreement. There shall be no obligation of the Fund, on behalf of a Portfolio, to reimburse DFA for waived fees or expenses that were assumed by DFA more than thirty-six months prior to the date of any such reimbursement.

3. Assignment. No assignment of this Agreement shall be made by DFA without the prior consent of the Fund.

4. Duration and Termination. This Agreement shall continue in effect until April 1, 2008 for each Portfolio (or each class of a Portfolio) and shall continue in effect

from year to year thereafter for each Portfolio (or class of a Portfolio), unless and until the Fund or DFA notifies the other party to the Agreement, at least thirty days prior to the end of the one-year period for a Portfolio (or class of a Portfolio), of its intention to terminate the Agreement for a Portfolio (or class of a Portfolio). This Agreement shall automatically terminate, with respect to a Portfolio (or class of a Portfolio), upon the termination of the Administration Agreement between DFA and the Fund, on behalf of such Portfolio.

IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of the date first-above written.
