RE: Ariel Investment Trust Line of Credit

Ladies and Gentlemen:

State Street Bank and Trust Company (the “Bank”) is pleased to make available, on an uncommitted discretionary basis, a $125,000,000.00 unsecured demand line of credit (the “Uncommitted Line”) to Ariel Investment Trust, a Massachusetts business trust registered under the Investment Company Act (the “Borrower”), on behalf of its fund series from time to time listed on Appendix I attached hereto (each such fund series, a “Fund”), on the following terms and conditions:

I. Uncommitted Line

1. Term. The Uncommitted Line shall commence on the date hereof and expire April 14, 2009 (the “Expiration Date”), unless extended by mutual agreement of the Bank and the Borrower or, with respect to any Fund, terminated by the Borrower on behalf of such Fund as provided herein. The Borrower, on behalf of a Fund, may terminate the Uncommitted Line with respect to such Fund upon three (3) days prior written notice and payment of all outstanding principal, interest, fees, costs, expenses and other amounts owing by such Fund to the Bank hereunder on the effective date of termination.

2. Notice and Manner of Borrowings. In the sole and absolute discretion of the Bank and in any event subject to the terms and conditions hereof, the Bank may make revolving loans to the Borrower on behalf of any Fund under the Uncommitted Line (each such loan, a “Loan”); provided that, in each case after giving effect to the requested Loan, (i) the aggregate outstanding Indebtedness for borrowed money of such Fund (including the aggregate principal amount of all Loans outstanding to such Fund) shall not exceed the Maximum Amount applicable to such Fund, (ii) the aggregate principal amount of Loans outstanding to such Fund hereunder shall not exceed the Uncommitted Line Amount, and (iii) the aggregate principal amount of Loans outstanding to the Borrower, on behalf of all Funds hereunder, shall not exceed the Uncommitted Line Amount. Each request for a Loan hereunder shall be made in writing by the Borrower, on behalf of a Fund, by delivering a completed loan request in the form of Exhibit B attached hereto and such other information or documentation as the Bank may reasonably request. Each such Loan request shall be made by the Borrower, on behalf of a Fund, and received by the Bank not later than 3:00 p.m., Boston time, on the Business Day on which such Loan is to be made. Each Loan request hereunder shall be deemed to be a confirmation by the Borrower, on behalf of the applicable Fund, that no Default or Event of Default has occurred and is continuing hereunder with respect to the Borrower or such Fund, that the representations and warranties of the Borrower, on behalf of such Fund, described below remain true and correct in all material respects, and that no borrowing limitations applicable to the Fund or the Uncommitted Line (including those set forth in clauses (i) through (iii) of the proviso above in this Section) will be exceeded after giving effect to the requested Loan, each of which shall be a precondition to the making of any Loan hereunder. Notwithstanding the foregoing, the Borrower agrees and understands that the making of any Loan hereunder shall remain in the sole and absolute discretion of the Bank and the Bank shall have no commitment with respect thereto.

3. Evidence of Indebtedness. All Loans will be evidenced by a demand promissory note in the form attached hereto as Exhibit A executed by the Borrower, on behalf of each of the Funds (as amended, restated, extended, replaced or otherwise modified and in effect from time to time, the “Note”). The Borrower, on behalf of each Fund, hereby authorizes the Bank to record each Loan and the corresponding information on the schedule forming part of the Note, and, absent manifest error, this record shall govern and control. The failure by the Bank to record, or any error in so recording, any such amount on the Bank’s books and records, such schedule, or any other record maintained by the Bank, shall not limit or otherwise affect the obligation of the Borrower, on behalf of each Fund, to make payments of principal of and interest on each Loan as provided herein and in the Note.

4. Interest Rate. Principal on each outstanding Loan shall bear interest at a variable rate per annum equal to the Federal Funds Rate plus a spread, as determined and quoted by the Bank in its sole discretion at the time of the request for a Loan, which rate shall be subject to change from time to time at the sole discretion of the Bank. Interest on each Loan shall be calculated on the basis of a 360-day year for the actual number of days elapsed. Following and during the continuance of a Default or an Event of Default hereunder, unpaid principal on any Loan, and to the extent permitted by applicable law, unpaid interest on any Loan, shall thereafter bear interest, compounded monthly and payable on demand, until paid in full (after as well as before judgment) at a rate per annum equal to two percent (2%) above the rate otherwise applicable to such Loan hereunder.

5. Payments and Prepayments; Recourse. (a) The Borrower, on behalf of each of the Funds, hereby promises to pay accrued interest on all Loans monthly in arrears on the first day of each calendar month for the immediately preceding calendar month; provided, however, that in each such case if such day on which interest on any Loans is due is not a Business Day, interest shall be payable on the next preceding Business Day. The Borrower, on behalf of each of the Funds, hereby promises to repay the principal amount of each outstanding Loan, together with all accrued and unpaid interest thereon, upon the earliest of (i) 60 days following the date on which such Loan is made, (ii) the date on which such Loan becomes due pursuant to Section II(4) below following the occurrence of an Event of Default, (iii) demand by the Bank or (iv) the Expiration Date. The Borrower, on behalf of each Fund, further covenants and agrees to immediately repay (1) the outstanding aggregate principal amount of any Indebtedness for borrowed money of any such Fund at any time (including the then outstanding aggregate principal amount of all Loans to such Fund) to the extent such amount exceeds the Maximum Amount applicable to such Fund at such time, and (2) any amount by which the then outstanding aggregate principal amount of all Loans to any such Fund at any time exceeds the Uncommitted Line Amount, in each case upon the earlier to occur of the Borrower first becoming aware of any such circumstance or demand by the Bank. The Borrower, on behalf of each Fund having Loans outstanding at any time, further covenants and agrees that it shall make such repayments of the Loans outstanding to each such Fund at any time to the extent required such that the then outstanding aggregate principal amount of all Loans to all Funds hereunder shall at no time exceed the Uncommitted Line Amount, in each case upon the earlier to occur of the Borrower first becoming aware of any such circumstance or demand by the Bank. Loans may be prepaid at the option of the Borrower without penalty or premium, and any amounts prepaid may, in the Bank’s sole discretion and otherwise subject to the terms hereof, be reborrowed. Notwithstanding the foregoing or any other provision of this Agreement, there shall be a period consisting of at least 1 Business Day during each 60 day-period during which this Agreement is in effect

when no Loans are outstanding. The Borrower promises to make such payments of one or more Loans as are necessary to comply with the foregoing sentence.

(b) All payments by the Borrower, on behalf of each Fund, hereunder and under any of the other Loan Documents shall be made not later than 3:00 p.m. Boston time on the date due in immediately available United States dollars at the Bank’s office at 100 Huntington Avenue, Tower 2, Floor 4, Boston, Massachusetts or as otherwise directed in writing by the Bank. All such payments by the Borrower, on behalf of each Fund, hereunder and under any of the other Loan Documents shall be made without recoupment, setoff or counterclaim and free and clear of and without deduction for any taxes, levies, imposts, duties, charges, fees, deductions, withholdings, compulsory loans, restrictions or conditions of any nature now or hereafter imposed or levied by any jurisdiction or any political subdivision thereof or taxing or other authority therein unless the Borrower is compelled by law to make such deduction or withholding. If any such obligation is imposed upon the Borrower with respect to any amount payable by it hereunder or under any of the Loan Documents, the Borrower will pay to the Bank, on the date on which such amount is due and payable hereunder or under the Loan Documents, such additional amount in United States dollars as shall be necessary to enable the Bank to receive the same net amount which the Bank would have received on such due date had no such obligation been imposed upon the Borrower. The Borrower will deliver promptly to the Bank certificates or other valid vouchers for all taxes or other charges deducted from or paid with respect to payments made by the Borrower hereunder or under the Loan Documents.

(c) The Bank and the Borrower acknowledge and agree that the Bank shall look solely to the property of each Fund for the enforcement of any claim against such Fund. None of the trustees, officers, employees, agents or shareholders of the Borrower or any Fund assumes any personal liability for the obligations entered into by the Borrower, on behalf of each Fund, with respect to the Uncommitted Line. In addition, the principal amount of any Loan, and accrued interest thereon, and any fees, costs, expenses, indemnities or other amounts payable in connection with or relating to any Fund or any Loan pursuant to this Agreement (other than any fees, costs, expenses, indemnities or other amounts payable to the Bank pursuant to the terms hereof not specific or identifiable to any Fund or Funds or any particular Loan), shall be paid or repaid solely from the assets of the Fund to which such Loan is made, and the Bank shall have no right of recourse or offset against the assets of any other Fund or any other series of the Borrower for such amounts. Each Fund shall be severally liable to the Bank hereunder for fees, costs, expenses, indemnities or other amounts owed to the Bank pursuant to the terms hereof that are not specific or identifiable to any Fund or Funds or any particular Loan in accordance with such Fund’s Ratable Percentage thereof from time to time.

6. Use of Loan Proceeds. Proceeds of Loans may be used only (a) for temporary or emergency purposes consistent with the then current investment objectives and fundamental investment restrictions of the Fund on behalf of which a Loan is made, provided that each such Loan shall constitute an “Exempted Transaction” under Federal Reserve Regulation U, (b) to finance temporarily the purchase or sale of securities for prompt delivery if the Loan is to be repaid promptly in the ordinary course of business upon completion of such purchase or sale transaction or (c) to finance the redemption of the shares of an investor of the Fund on behalf of which a Loan is made. Each Loan shall be made in compliance with, and subject to, Federal Reserve Regulation U and no portion of any proceeds of any Loan shall be used directly or indirectly in violation of any provision of any statute, regulation, order or restriction applicable to the Bank, the Borrower or any Fund.

7. Addition of Borrowers and Funds. With the prior written consent of the Bank in its sole discretion and in any event no more than once per calendar quarter, the Borrower may request the addition to the terms of this Agreement of any additional fund series of the Borrower. In no event will any such additional fund series be added to the terms of this Agreement if such fund series is advised or sub-advised by an affiliate of the Bank. The addition of any such fund series shall be subject to consent by the Bank in its sole discretion and completion of an appropriate amendment to this Agreement and such other documentation as the Bank may require, including without limitation then-current prospectus and related information; corporate, trust or similar existence and authorization documentation; and appropriate legal opinions, in each case with respect to any proposed new Fund as the Bank may require.

II. General Loan Terms

1. Covenants. Until all obligations of the Borrower and each Fund with respect to the Uncommitted Line have been paid in full and the Uncommitted Line has been terminated, unless otherwise consented to in writing by the Bank, the Borrower hereby covenants and agrees on behalf of each Fund (the Borrower acknowledging that compliance with the following covenants shall not in any way compromise the absolute discretion of the Bank whether or not to make Loans under the Uncommitted Line and whether or not to demand repayment of any outstanding amounts at any time for any reason):

Notwithstanding anything to the contrary in Section II(1)(g) above, but without in any way limiting the rights of the Bank set forth therein, unless the Bank shall request paper copies of the financial and other information otherwise required to be furnished by the Borrower to the Bank pursuant to subsections (i) and (ii) of such Section II(1)(g) above, the Borrower may deliver all such information to the Bank in a printable format by electronic means. The Borrower may make such electronic delivery by: (i) sending such information as an electronic mail attachment to such electronic mail addresses as shall be designated by the Bank, as applicable; or (ii) notifying the Bank by electronic mail (to such electronic mail addresses as shall be designated by the Bank, as applicable) that the documents are available on a website accessible to the Bank and further indicating a website hyperlink directing the user directly to the referenced documents posted thereon; provided that such information shall be made available on or before the dates specified in said subsections (i) and (ii) of such Section II(1)(g) above. Nothing contained in this paragraph shall require the Bank to maintain copies of the financial and other information referred to in this paragraph, and the Bank shall be solely responsible for requesting physical delivery of such information, or maintaining any such information, as applicable. The Borrower, on behalf of each Fund, acknowledges that the distribution of material through an electronic medium is not necessarily secure and that there may be confidentiality and other risks associated with such distribution. In no event shall the Bank or any of its officers, directors, employees, agents, advisors or representatives have any liability to the Borrower or any Funds for damages of any kind, including without limitation, direct or indirect, special, incidental or consequential damages, losses or expenses arising out of the Borrower’s transmission of communications through the internet.

4. Remedies. Upon the occurrence of an Event of Default described in Section II(3)(e) or (f), immediately and automatically; and upon the occurrence of any other Event of Default at any time thereafter while such Event of Default is continuing, at the Bank’s option and upon the Bank’s declaration:

(a) the Uncommitted Line established hereunder shall terminate with respect to the applicable Fund(s);

(b) the unpaid principal amount of the Loans to the Borrower on behalf of the applicable Fund(s), together with accrued and unpaid interest thereon, all fees, expenses and other Obligations, shall become immediately due and payable without presentment, demand, protest or further notice of any kind, all of which are hereby expressly waived; and

(c) the Bank may exercise any and all rights it has under any of the Loan Documents and proceed to protect and enforce the Bank’s rights by any action at law, in equity or other appropriate proceeding as it relates to the applicable Fund(s).

Subject to the terms of Section I(5)(c) above, the Borrower, on behalf of each Fund, authorizes the Bank and the Custodian, following the occurrence and during the continuance of an Event of Default or following demand by the Bank for repayment of the Obligations, to charge and setoff against any deposit account or other account maintained with either the Bank or the Custodian on behalf of the Borrower, on behalf of each Fund, and apply the proceeds thereof against repayment of any unpaid

Obligations of the Borrower on behalf of such Fund, as appropriate. In addition, the Custodian, following the occurrence and during the continuance of an Event of Default or following demand by the Bank for repayment of the Obligations, is hereby directed by the Borrower, on behalf of each Fund, to dispose of such Fund’s assets as selected by the Investment Adviser to the extent necessary to repay all amounts due to the Bank from the Borrower, on behalf of such Fund, to the extent that the Obligations of the Borrower, on behalf of such Fund, have not been paid when due or if any other Event of Default has occurred. If the Investment Adviser does not select a sufficient amount of assets to repay all amounts due to the Bank from the Borrower, on behalf of such Fund, within a reasonable time, the Custodian is hereby directed by the Borrower, on behalf of such Fund, upon one day’s prior written notice to the Borrower, on behalf of such Fund, and its Investment Adviser, to dispose of such Fund’s assets to the extent necessary to repay all amounts due to the Bank from the Borrower, on behalf of such Fund. The foregoing shall be deemed to be continuing and irrevocable “proper instructions” to the Custodian for all purposes under the applicable custody agreement between the Borrower, on behalf of such Fund, and the Custodian.

For value received, each of the undersigned hereby promises to pay to State Street Bank and Trust Company (the “Bank”), or order, at the office of the Bank at 100 Huntington Avenue, Tower 2, Floor 4, Boston, Massachusetts 02116 in immediately available United States dollars, UPON DEMAND by the Bank, the principal amount of ONE HUNDRED TWENTY-FIVE MILLION AND 00/100 DOLLARS ($125,000,000.00), or such lesser original principal amount as shall be outstanding hereunder and not have been prepaid as provided herein, together with interest thereon as provided below. Each Loan shall be payable upon the earliest to occur of (a) the Expiration Date, (b) 60 calendar days following the date on which such Loan is made, (c) demand by the Bank, or (d) the date on which such Loan otherwise becomes due and payable under the terms of the Loan Agreement referred to below, whether following the occurrence of an Event of Default or otherwise. Interest on the unpaid principal amount outstanding hereunder shall be payable at the rates and at the times as set forth in the Loan Agreement and shall be computed as set forth in the Loan Agreement. Interest shall be computed on the basis of a 360-day year for the actual number of days elapsed, including holidays or other days on which the Bank is not open for the conduct of banking business.

All Loans hereunder and all payments on account of principal and interest hereof shall be recorded by the Bank. The entries on the records of the Bank (including any appearing on this Note), absent manifest error, shall govern and control as to amounts outstanding hereunder, provided that the failure by the Bank to make any such entry shall not affect the obligation of the undersigned to make payments of principal and interest on all Loans as provided herein and in the Loan Agreement.

Following the occurrence of a Default or an Event of Default, unpaid principal on any Loan, and to the extent permitted by applicable law, unpaid interest on any Loan, shall thereafter bear interest, compounded monthly and be payable on demand, until paid in full (after as well as before judgment) at a rate per annum equal to two percent (2%) above the rate otherwise applicable to such Loan under the Loan Agreement.

This Note is issued pursuant to, and entitled to the benefits of, and is subject to, the provisions of a certain letter agreement dated April 15, 2008 by and among the undersigned and the Bank (herein, as the same may from time to time be amended, restated, supplemented, modified or extended, referred to as the “Loan Agreement”), but neither this reference to the Loan Agreement nor any provision thereof shall affect or impair the absolute and unconditional obligation of the undersigned makers of this Note to pay the principal of and interest on this Note as herein provided. All terms not otherwise defined herein shall be used as defined in the Loan Agreement.

The undersigned may at its option prepay all or any part of the principal of this Note subject to the terms of the Loan Agreement. Amounts prepaid may be reborrowed subject to the terms of the Loan Agreement.

Each of the undersigned makers and every endorser and guarantor hereof hereby waives presentment, demand, notice, protest and all other demands and notices in connection with the delivery,

acceptance, performance, default or enforcement hereof and consents that this Note may be extended from time to time and that no such extension or other indulgence, and no substitution, release or surrender of collateral and no discharge or release of any other party primarily or secondarily liable hereon, shall discharge or otherwise affect the liability of any of the undersigned or any such endorser or guarantor. No delay or omission on the part of the Bank in exercising any right hereunder shall operate as a waiver of such right or of any other right hereunder, and a waiver of any such right on any one occasion shall not be construed as a bar to or waiver of any such right on any future occasion.

The Bank and the Borrower acknowledge and agree that the Bank shall look solely to the property of each Fund for the enforcement of any claim against such Fund. None of the trustees, officers, employees, agents or shareholders of the Borrower or any Fund assumes any personal liability for the obligations entered into by the Borrower, on behalf of each Fund, with respect to the Loan Agreement.

This instrument shall have the effect of an instrument executed under seal and shall be governed by and construed in accordance with the laws of The Commonwealth of Massachusetts (without giving effect to any conflicts of laws provisions contained therein).
