Social and Environmental Standards
To determine which securities are eligible for investment by the Fund, Domini will evaluate current and potential holdings against its social and environmental standards to assess the quality of a corporation’s relations with communities, customers, ecosystems, employees, investors, and suppliers. Domini may determine that a security is eligible for investment even if a corporation’s

profile reflects a mixture of positive and negative social and environmental characteristics.

¹Until November 30, 2010, Domini Social Investments LLC has contractually agreed to waive certain fees and/or reimburse certain expenses, including management fees, so that the Fund's expenses, net of waivers and reimbursements will not exceed, on a per annum basis, 0.80% of the daily net assets representing Institutional shares, absent an earlier modification by the Fund’s Board of Trustees.

²Institutional share accounts may only be established by or for the benefit of investors that have been approved by the distributor, meet the minimum investment and other requirements described below, and fall within the following categories: endowments, foundations, religious organizations, other nonprofit entities, individuals, retirement plan sponsors, certain corporate or similar institutions, and omnibus accounts maintained by financial intermediaries.

The minimum initial investment is generally $2,000,000 for an account, provided that defined contribution plan accounts must meet a minimum initial investment requirement of $10 million. Investors may meet the minimum initial investment amount by aggregating up to three separate Institutional share accounts (other than retirement plan accounts).  Defined contribution plan accounts meet eligibility levels at the sponsor level.  Defined contribution plan accounts cannot be aggregated with defined contribution plans of unaffiliated sponsors to meet the $10 million minimum initial investment amount.

Institutional share accounts will not be established for omnibus or other accounts for which Domini provides recordkeeping and other shareholder services or for which the Fund is required to pay any type of administrative payment per participant account.

The Fund may change any of the policies described above at any time.

The Domini Social Equity Fund is not insured and is subject to market risks. You may lose money. Although the Domini Social Equity Fund Institutional shares are no-load, certain fees and expenses apply to a continued investment and are described in the prospectus. The composition of the Fund's portfolio is subject to change.
