AGREEMENT made this 28^th day of September, 2021, by and between DFA INVESTMENT DIMENSIONS GROUP INC., a Maryland corporation (the “Fund”), on behalf of the Emerging Markets ex China Core Equity Portfolio (the “Portfolio”), a separate series of the Fund, and DIMENSIONAL FUND ADVISORS LP, a Delaware limited partnership (the “Manager”).

1. Investment Advisory Services. The Fund hereby employs the Manager to manage the investment and reinvestment of the assets of the Portfolio, to review and supervise the investment and reinvestment of the assets of the Portfolio, to determine in its discretion the securities and instruments to be purchased or sold and the portion of the Portfolio’s assets to be uninvested, to provide the Fund with records concerning the Manager’s activities which the Fund is required to maintain, and to render regular reports to the Fund’s officers and the Board of Directors of the Fund (the “Board”), all in compliance with the investment objective(s), policies, and limitations set forth in the Portfolio’s registration statement, and applicable laws and regulations, or as the Fund may instruct the Manager in writing. The Manager accepts such employment and agrees to provide, at its own expense, the office space, furnishings and equipment, and the personnel required by it to perform the investment advisory services described herein on the terms and for the compensation provided herein.

2. Portfolio Transactions. The Manager is authorized to select the brokers or dealers that will execute the purchases and sales of portfolio securities for the Portfolio and is directed to use its best efforts to obtain the best available prices and most favorable executions, except as prescribed herein. It is understood that the Manager will not be deemed to have acted unlawfully, or to have breached a fiduciary duty to the Fund or to the Portfolio, or be in breach of any obligation owing to the Fund or to the Portfolio under this Agreement, or otherwise, solely by reason of its having caused the Portfolio to pay a member of a securities exchange, a broker, or a dealer a commission for effecting a securities transaction for the Portfolio in excess of the amount of commission another member of an exchange, broker, or dealer would have charged if the Manager determines in good faith that the commission paid was reasonable in relation to the brokerage or research services provided by such member, broker, or dealer, viewed in terms of that particular transaction or the Manager’s overall responsibilities with respect to its accounts, including the Fund, as to which it exercises investment discretion. The Manager will promptly communicate to the officers and directors of the Fund such information relating to transactions for the Portfolio as they may reasonably request.

SUB-ADVISORY AGREEMENT

AGREEMENT dated this 28^th day of September, 2021 among DFA INVESTMENT DIMENSIONS GROUP INC., a Maryland corporation (the “Fund”), DIMENSIONAL FUND ADVISORS LP, a Delaware limited partnership (“DFA”), and DFA AUSTRALIA LIMITED, a corporation organized under the laws of New South Wales (“DFA Australia”).

WHEREAS, DFA is the investment advisor to all the portfolios of the Fund, including the Emerging Markets ex China Core Equity Portfolio (the “Portfolio”); and

WHEREAS, the Portfolio invests in securities of issuers associated with international markets designated by the Investment Committee of DFA, as categorized, defined, and limited in accordance with the Fund’s prospectus; and

WHEREAS, DFA Australia personnel have expertise in certain business areas pertinent to the business operations of the Portfolio and the selection of brokers or dealers and the execution of trades with respect to international securities; and

WHEREAS, DFA wishes to retain DFA Australia as sub-advisor with respect to the Portfolio, and DFA Australia wishes to act as sub-advisor, upon the terms hereinafter set forth.

NOW, THEREFORE, in consideration of the premises and mutual covenants and conditions contained herein, the parties hereto agree as follows:

1. Services to Be Performed. DFA hereby employs, subject to approval by the Board of Directors of the Fund and supervision by DFA, DFA Australia to furnish, at DFA Australia’s expense, the services described below with respect to the Portfolio:

DFA Australia shall have the authority and responsibility to select brokers or dealers to execute purchases and sales of eligible securities for the Portfolio. Such authority and responsibility shall include, without limitation, (i) providing investment and ancillary services for DFA and determining the best and most efficient means of purchasing and selling such portfolio securities in order to receive best price and execution, and (ii) allocating trades among brokers and dealers, including any affiliate of the Fund or of any investment advisor or affiliate thereof, subject to Section 17 of the Investment Company Act of 1940, as amended (the “1940 Act”). In carrying out its obligations hereunder, DFA Australia will act with a view to the Portfolio’s objectives, as set forth in the Fund’s registration statement, and otherwise communicated to DFA Australia by DFA, including the objectives of receiving best price and execution for portfolio transactions and of causing as little price fluctuation as possible. DFA Australia shall not receive any commission or rebate from any broker or dealer to whom it allocates trades nor shall it receive any commission from DFA based upon the allocation of trades. DFA will advise DFA Australia of changes in the Fund’s Amended and Restated Articles of Incorporation, Amended and Restated By-Laws, and registration statement, and any objectives not

appearing therein, as they may be relevant to DFA Australia’s performance under this Agreement. DFA will furnish to DFA Australia reports on cash available for investment and needed for redemption payments. DFA shall be responsible to the Board of Directors of the Fund for the preparation of schedules of securities eligible for purchase and sale by the Portfolio (“execution schedules”), and shall prepare such schedules on at least a semi-annual basis, it being understood that DFA may consult with DFA Australia in connection therewith, and may delegate to DFA Australia the preparation of such schedules. On at least a semi-annual basis, DFA will review the Portfolio’s holdings, make, itself or in consultation with DFA Australia, any necessary adjustments to the execution schedules, and review the securities trading process and executions. DFA Australia is authorized to have orders executed for more or fewer shares than set forth on the execution schedules when market conditions and other factors permit or require, provided that such variances from the execution schedules are within the parameters agreed to by DFA, from time to time, or in specific cases. DFA Australia shall report the results of all trading activities and all such other information relating to portfolio transactions for the Portfolio as DFA may reasonably request, on a daily basis to DFA and any other entity designated by DFA, including, without limitation, the custodian of the Fund. DFA Australia shall review and coordinate its agency trading and execution strategies, practices, and results with DFA as frequently as reasonably requested.

DFA Australia shall maintain, and periodically review with DFA and the Fund, policies and procedures necessary to ensure the effectiveness of on-line communications systems between DFA Australia, DFA, and the Fund.

DFA Australia shall periodically provide DFA with data concerning the international markets, and it shall maintain and provide to DFA current financial information with respect to specific international securities on the execution schedules. DFA Australia shall also furnish DFA with advice and information regarding securities of international companies and shall provide DFA with such recommendations in connection with the investment therein by the Portfolio as DFA Australia shall deem necessary and advisable in light of the investment objective and policies of the Portfolio.

2. Compensation. For the services provided by DFA Australia hereunder, DFA shall pay DFA Australia a fee equal to $13,000 (U.S.) per year, to be paid on a quarterly basis. In the event that this Agreement is terminated at other than quarter-end, the fee for such quarter shall be prorated.

3. Liability of DFA Australia. DFA Australia shall not be liable for any error of judgment or of law or for any loss suffered by the Fund in connection with the matters to which this Agreement relates, except loss resulting from willful misfeasance, bad faith, or gross negligence on the part of DFA Australia in the performance of its obligations and duties, or by reason of its reckless disregard of its obligations and duties under this Agreement.

4. Term. This Agreement shall become effective as of September 28, 2021, and shall remain in effect until September 28, 2023, unless sooner terminated as hereinafter provided and shall continue in effect from year to year thereafter, but only so long as such continuance is specifically approved, at least annually, by: (a) the vote of a majority of the Fund’s Directors, or (b) the vote of a majority of the outstanding voting securities of the Portfolio, and (c) the vote of a majority of those Directors who are not parties to this Agreement or interested persons of any such party (except as Directors of the Fund) cast in person at a meeting called for the purpose of voting on such approval. The terms “interested persons” and “vote of a majority of the outstanding voting securities” shall have the meanings respectively set forth in Section 2(a)(19) and Section 2(a)(42) of the 1940 Act.

This Agreement may be terminated by DFA or by DFA Australia at any time, without penalty, on ninety (90) days’ written notice to the other party hereto, and may also be terminated at any time without penalty by the Board of Directors of the Fund or by vote of the holders of a majority of the outstanding voting securities of the Portfolio on sixty (60) days’ written notice to DFA Australia by the Fund.

This Agreement shall automatically terminate in the event of its assignment. The term “assignment” for this purpose shall have the meaning set forth in Section 2(a)(4) of the 1940 Act.

This Agreement shall automatically terminate with respect to the Portfolio in the event that the Investment Management Agreement for the Portfolio between DFA and the Fund is terminated, assigned, or not renewed.

5. DFA Australia will promptly notify DFA and the Fund of any change in the composition of its Board of Directors.

6. Notice. Any notice under this Agreement shall be in writing, addressed and delivered or mailed, postage prepaid, to the other party at such address as such other party may designate for the receipt of such notices.

7. Governing Law and Consent to Jurisdiction. This Agreement shall be governed by, and construed in accordance with, the laws of the State of Maryland without giving effect to the conflict of laws principles thereof; provided that nothing herein shall be construed to preempt, or to be inconsistent with, any U.S. federal law, regulation or rule, including the 1940 Act and the Investment Advisers Act of 1940, as amended and any rules and regulations promulgated thereunder. The parties agree and consent to the jurisdiction of the State and federal courts of Maryland.

FEE WAIVER AND EXPENSE ASSUMPTION AGREEMENT

FEE WAIVER AND EXPENSE ASSUMPTION AGREEMENT, made this 28^th day of September, 2021, between DFA Investment Dimensions Group Inc., a Maryland corporation (the “Fund”), on behalf of the Emerging Markets ex China Core Equity Portfolio (the “Portfolio”), and Dimensional Fund Advisors LP, a Delaware limited partnership (“Dimensional”).

WHEREAS, Dimensional has entered into an Investment Management Agreement with the Fund, on behalf of the Portfolio, pursuant to which Dimensional provides investment management services for the Portfolio, and for which Dimensional is compensated based on the average net assets of the Portfolio; and

WHEREAS, the Fund and Dimensional have determined that it is appropriate and in the best interests of the Portfolio and its shareholders to limit the expenses of the Portfolio;

NOW, THEREFORE, the parties hereto agree as follows:

Fee Waiver and Expense Assumption by Dimensional. Dimensional agrees to waive all or a portion of its management fee and to assume the ordinary operating expenses of the Institutional Class of the Portfolio (including the expenses that the Portfolio bears as a shareholder of other funds managed by Dimensional, excluding money market funds, but excluding the expenses that the Portfolio incurs indirectly through its investment in unaffiliated investment companies) (“Portfolio Expenses”) to the extent necessary to limit the Portfolio Expenses of the Institutional Class of the Portfolio to 0.43 of 1% of the average net assets of the Institutional Class of the Portfolio on an annualized basis (the “Expense Limitation Amount”).

Duty to Reimburse Dimensional. If, at any time, the Portfolio Expenses of a class of the Portfolio are less than the Expense Limitation Amount for such class of shares of the Portfolio, the Fund, on behalf of the Portfolio, shall reimburse Dimensional for any fees previously waived and/or expenses previously assumed to the extent that such reimbursement will not cause the annualized Portfolio Expenses for such class of shares of the Portfolio to exceed the Expense Limitation Amount. There shall be no obligation of the Fund, on behalf of the Portfolio, to reimburse Dimensional for fees waived or expenses previously assumed by Dimensional more than thirty-six (36) months prior to the date of such reimbursement.

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

Duration and Termination. This Agreement shall begin on September 28, 2021, and shall continue in effect until February 28, 2023, and shall continue in effect from year to year thereafter, unless and until the Fund or Dimensional notifies the other party to the Agreement, at least thirty days (30) prior to the end of the one-year period for the Portfolio, of its intention to terminate the Agreement. This Agreement shall automatically terminate upon the termination of the Investment Management Agreement between Dimensional and the Fund, on behalf of the Portfolio.

The Fund has filed, with the U.S. Securities and Exchange Commission, a Registration Statement under the Securities Act for each Fund, which Registration Statement is deemed to register an indefinite number of shares of the Fund pursuant to the provisions of Section 24(f) of the Investment Company Act. You further have advised us that the Fund has filed, and each year hereafter will timely file, a Notice pursuant to Rule 24f-2 under the Investment Company Act perfecting the registration of the shares sold by the Fund during each fiscal year during which such registration of an indefinite number of shares remains in effect.

You also have informed us that the shares of the Fund registered under the Securities Act have been, and will continue to be, sold in accordance with the Fund’s usual method of distributing its registered shares, under which prospectuses are made available for delivery to offerees and purchasers of such shares in accordance with Section 5(b) of the Securities Act.

Based upon the foregoing information and examination, so long as the Fund remains a valid and subsisting entity under the laws of its state of organization, and the registration of an indefinite number of shares of the Fund remains effective, the authorized shares of the Fund, when issued for the consideration set by the Board of Directors pursuant to the Articles, and subject to compliance with Rule 24f-2, will be legally outstanding, fully-paid, and non-assessable shares, and the holders of such shares will have all the rights provided for with respect to such holding by the Articles and the laws of the State of Maryland.

We hereby consent to the use of this opinion, in lieu of any other, as an exhibit to the Registration Statement of the Fund, along with any amendments thereto, covering the registration of the shares of the Fund under the Securities Act and the applications, Registration Statements or notice filings, and amendments thereto, filed in accordance with the securities laws of the several states in which shares of the Fund are offered, and we further consent to reference in the Registration Statement of the Fund to the fact that this opinion concerning the legality of the issue has been rendered by us.


Very truly yours,
