DOMINI SOCIAL INVESTMENT TRUST (f/k/a Domini Social Index Trust), a
Massachusetts business trust (the Fund) and INVESTORS BANK & TRUST COMPANY, a

         WHEREAS the Fund and Investors Bank entered into a Custody Agreement
dated June 3, 1993, as amended from time to time (the Custodian Agreement); and

         WHEREAS, the Fund and Investors Bank desire to amend the Custodian
Agreement as set forth below.

         NOW, THEREFORE, in consideration of the premises and of the mutual
covenants and agreements herein set forth, the parties hereto agree as follows:

1.       Amendments.

         (a) The Custodian Agreement is hereby amended by inserting following
section as 6. B.(e):

         The Bank receives class action litigation information from several
         standard sources. The Bank may also obtain Proof of Claim forms
         directly from the major class action claims administrators. The Banks
         Class Action Unit obtains the transaction activity of all custodied
         clients, including the Funds, from the specified class period. The
         transaction information is systematically extracted from the Banks
         system and electronically filed with the Claims Administrator. The Bank
         will participate in all class action litigations on behalf of the Funds
         unless Adviser specifically requests that the Bank not file. The Bank
         shall not be responsible for the filing of any information in
         connection with class action litigations on behalf of the Funds at any
         time at which this Custody Agreement is no longer in effect. The Bank
         shall not be responsible for the filing of any information in
         connection with class action litigations on behalf of the Funds for
         periods prior to the beginning of the Funds Custody relationship with
         the Bank.


         (b) Appendix A of the Custody Agreement is hereby amended by deleting
such Appendix A in its entirety and inserting in lieu thereof the attached
Appendix A.


2.       Miscellaneous.

         (a) Except as amended hereby, the Custodian Agreement shall remain in
full force and effect.

         (b) This Amendment may be executed in two or more counterparts, each of
which shall be deemed an original, but all of which together shall constitute
one and the same instrument.
