Exhibit A

                AMENDMENT TO TRANSFER AGENCY SERVICES AGREEMENTS

     THIS AMENDMENT (this "Amendment") to the Transfer Agency and Services
Agreements dated as of October 1, 2003 and / or November 8, 2004 (collectively,
the "Agreements" or the "Agreement") by and between PFPC INC., a Massachusetts
corporation ("PFPC"), and each of the Domini Social Investment Trust, Domini
Advisor Trust and Domini Institutional Trust (hereafter, collectively and
individually referred to, along with their agents, as the "Fund" or "Funds") is
made as of September 5, 2007. Capitalized terms used but not defined herein
shall have the same meaning as in the Agreement.

     1. Services. In addition to the services set forth in the Agreement, PFPC
shall provide to the Fund the services set forth in Exhibit A hereto relating to
the obligations of the Fund under SEC Rule 22c-2 under the Investment Company
Act of 1940, as amended ("Rule 22c-2"), and the Fund will pay to PFPC the fees
and charges in respect of such services set forth in Exhibit B hereto. The Fund
and/or DSIL Investment Services LLC "(DSILD") on behalf of each Fund has entered
and may enter into further agreements with financial intermediaries
(collectively, "Financial Intermediaries") under the terms of which such
Financial Intermediaries will be instructed to provide data to PFPC pursuant to
Rule 22c-2 relating to transactions in the Fund's shares. A form of such notice
to be provided by the Fund to each Financial Intermediary is attached as Exhibit
C hereto. PFPC shall not be liable to the Fund, its investors or any agents of
the Fund, including its investment advisor(s), for any errors or omissions in
any data provided to PFPC by any Financial Intermediaries or for compliance by
the Fund with SEC Rule 22c-2, to the extent that PFPC is not at fault. PFPC's
sole obligation under this Section 1 shall be to accurately provide the Fund
with timely access to information relating to transactions in the Fund's shares
based solely on information provided to PFPC by Financial Intermediaries.

     2. Systems. In providing the services described in Exhibit A hereto, PFPC
may, pursuant to licenses or other agreements (collectively, "Third Party
Agreements") with one or more unrelated parties (collectively, "Third Party
Providers"), utilize information, data, technology and systems (collectively,
"Third Party Systems") licensed or otherwise provided to PFPC by such Third
Party Providers. PFPC represents and warrants that it and the Third Party
Providers currently are and will remain, during the term of this Amendment, the
sole owners of (or have or will obtain valid licenses for) the hardware,
software, technology and systems comprising the Rule 22c-2 system being provided
for use by the Funds herein. The Fund will not use or disclose any confidential
information relating to Third Party Systems.

     3. Indemnification. The Fund agrees to indemnify, defend and hold harmless
PFPC and its affiliates, including their respective officers, directors, agents
and employees(collectively, "PFPC persons"), from all taxes, charges, expenses,
assessments, claims and liabilities (including, without limitation, attorneys'
fees and disbursements and liabilities arising under the securities laws, rules
and regulations of the United States (including SEC Rule 22c-2) or of any state
and any foreign country) ("Claim") arising

directly or indirectly from any action or omission to act which PFPC takes or
fails to take in connection with the provision of services to the Fund
hereunder, to the extent that PFPC and PFPC persons are not at fault. Neither
PFPC, nor any PFPC persons, shall be indemnified against any liability (or any
expenses incident to such liability) caused by PFPC's or PFPC persons' own
willful misfeasance, bad faith, negligence or reckless disregard in the
performance of PFPC's activities under this Amendment, material breach of this
Agreement, or the breach of any representation or warranty herein by PFPC. PFPC
agrees to indemnify, defend and hold harmless the Funds and their affiliates,
including their respective officers, directors, agents and employees, from all
Claims arising directly or indirectly from PFPC's or PFPC persons' own willful
misfeasance, bad faith, negligence or reckless disregard in the performance of
their activities under this Agreement, or the breach of any representation or
warranty of PFPC made herein. The provisions of this Section 3 shall survive
termination of this Amendment.

     4. Responsibility of PFPC.

          (a) PFPC shall be under no duty to take any action hereunder on behalf
     of the Fund except as specifically set forth herein or as may be
     specifically agreed to by PFPC and the Fund in a written amendment hereto.
     PFPC shall be obligated to exercise care and diligence in the performance
     of its duties hereunder and to act in good faith in performing services
     provided for under this Amendment. PFPC shall be liable only for any
     damages arising out of PFPC's failure to perform its duties under this
     Amendment to the extent such damages arise out of PFPC's willful
     misfeasance, bad faith, negligence or reckless disregard of such duties, or
     the breach of any representation or warranty of PFPC made herein.

          (b) Notwithstanding anything in this Amendment to the contrary, (i)
     PFPC shall not be liable for losses, delays, failure, errors, interruption
     or loss of data occurring directly or indirectly by reason of circumstances
     beyond its reasonable control, including without limitation acts of God;
     action or inaction of civil or military authority; public enemy; war;
     terrorism; riot; fire; flood; sabotage; epidemics; labor disputes; civil
     commotion; interruption, loss or malfunction of utilities, transportation,
     computer or communications capabilities; insurrection; elements of nature;
     or non-performance by a third party; and (ii) PFPC shall not be under any
     duty or obligation to inquire into and shall not be liable for the validity
     or invalidity, authority or lack thereof, or truthfulness or accuracy or
     lack thereof, of any instruction, direction, notice, instrument or other
     information from an officer of the Fund which PFPC reasonably believes to
     be genuine.

          (c) Notwithstanding anything in this Agreement to the contrary,
     neither PFPC, Fund nor their affiliates shall be liable for any
     consequential, special or indirect losses or damages, whether or not the
     likelihood of such losses or damages was known by such party or its
     affiliates


                                       2

          (d) Neither party may assert a cause of action against the other or
     any of its affiliates that allegedly occurred more than two (2) years
     immediately prior to the filing of the suit (or, if applicable,
     commencement of arbitration proceedings) alleging such cause of action.

          (e) Each party shall have a duty to mitigate damages for which the
     other party may become responsible.

          (f) The provisions of this Section 4 shall survive termination of the
     Agreement and this Amendment.

     5. Effective Date / Term of Amendment. This Amendment shall be effective as
     of the date hereof. Except as set forth in this Amendment, the Agreement
     shall continue in full and effect in accordance with its terms. This
     Amendment shall have a term concurrent with the Agreement. If neither party
     provides a written notice of non-continuance beyond the original term, this
     Amendment shall renew for one (1) year periods in accordance with the
     continuance procedures set forth in the Agreement. However, termination of
     this Amendment need not be concurrent with termination of the Agreement,
     and this Amendment may be terminated independent of the Agreement and vice
     versa.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be executed
as of the day and year first above written.

                                    EXHIBIT A
                                    SERVICES

o    The PFPC 22 c-2 system (the "System") is intended to enable the Fund to
     manage data requests to, and to access and analyze data provided by,
     Financial Intermediaries as required by SEC Rule 22c-2.

o    Pursuant to agreements between the Fund and Financial Intermediaries,
     Financial Intermediaries will deliver to PFPC, in electronic format,
     information on transactions effected in Fund shares.

o    The Fund may use the System to access data that is provided to PFPC by
     Financial Intermediaries or that is otherwise available to PFPC through
     NSCC for Financial Intermediaries that are NSCC members. The Fund may also
     use the System to request data from non-NSCC members.

o    The System is intended to be generally available to the Fund from 8:00 am
     to 6:00 pm Eastern Time during regular trading days, subject to periodic
     unavailability due to maintenance, upgrades, testing and potential System
     failures.

o    PFPC will work with the Fund to develop an implementation program with the
     objective of launching the System not later than the effective date of SEC
     Rule 22c-2. The implementation program will seek to identify and access
     sources of relevant data, including identification of omnibus accounts,
     Financial Intermediaries, NSCC membership status, CUSIPs, Fund shareholder
     accounts and Fund trading and redemption policies as set forth in the
     Fund's SEC registration statement and prospectuses. Designated
     representatives of the Fund will have access to the System. The System will
     be tested and de-bugged as necessary

o    The System implementation schedule will vary depending on the profile and
     requirements of the Fund, but is estimated to take at least 3-6 weeks. PFPC
     will provide project oversight and coordination, planning and review. PFPC
     will also assist the Fund in testing the System and training designated
     Fund representatives in use of the System.

o    PFPC will consider enhancements and improvements on request, with fees at
     rates to be negotiated.
