     Re: Expense Limitation Agreement

Ladies and Gentlemen:

     Domini Social Investments LLC currently provides oversight and
administrative and management services to Domini Advisor Trust (the "Trust"), a
Massachusetts business trust. We hereby agree with the Trust that we will waive
expenses payable to us by the Trust's series designated Domini EuroPacific
Social Equity Portfolio (the "Fund") or will reimburse the Fund for all expenses
payable by the Fund to the extent necessary so that the Fund's aggregate
expenses (excluding brokerage fees and commissions, interest, taxes, and other
extraordinary expenses), net of waivers and reimbursements, would not exceed, on
a per annum basis, 1.57% of that Fund's average daily net assets.

     The agreement in this letter shall take effect on November 30, 2007, and
shall remain in effect until November 30, 2008, absent an earlier modification
by the Board of Trustees, which oversees the Fund.

     Please sign below to confirm your agreement with the terms of this letter.

                                        Sincerely,

                                        Domini Social Investments LLC
