     INVESTMENT  SUBADVISORY AGREEMENT, made this ___ day of March, 2001, by and
between  CALVERT  ASSET  MANAGEMENT  COMPANY,  INC.,  a  Delaware  corporation
registered  as  an  investment advisor under the Investment Advisers Act of 1940
(the  "Advisor"),  and  African Harvest Asset Managers LIMITED, a ______________
corporation  (the  "Subadvisor").

     WHEREAS,  the Advisor is the investment advisor to the Calvert Impact Fund,
Inc. an open-end, diversified management investment company registered under the
Investment  Company  Act  of  1940,  as  amended  (the  "1940  Act");  and

     WHEREAS,  the  Advisor  desires to retain the Subadvisor to furnish it with
certain investment advisory services in connection with the Advisor's investment
advisory activities on behalf of the Calvert South Africa Fund series of Calvert
Impact  Fund,  Inc.  and  any additional series thereof, for which Schedules are
attached  hereto  (each  such  series  referred  to individually as the "Fund");

     NOW,  THEREFORE,  in  consideration  of  the  promises  and  the  terms and
conditions  hereinafter  set  forth,  it  is  agreed  as  follows:

     1.     Services  to  be  Rendered  by  the  Subadvisor  to  the  Fund.

     (a)  Investment  Program.  Subject  to  the  control of the Fund's Board of
Directors  ("Directors")  and  the  Advisor,  the  Subadvisor  at  its  expense
continuously will furnish to the Fund an investment program for such portion, if
any, of Fund assets designated by the Advisor from time to time. With respect to
such  assets, the Subadvisor will make investment decisions, which is subject to
Section  1(b)  of this Agreement, and will place all orders for the purchase and
sale  of  portfolio  securities.  The Subadvisor will for all purposes herein be
deemed  to  be an independent contractor and shall, except as expressly provided
or authorized, have no authority to act for or represent the Fund or the Advisor
in  any  way  or otherwise be deemed an agent of the Fund or the Advisor. In the
performance  of its duties, the Subadvisor will act in the best interests of the
Fund  and  will  comply with (i) applicable laws and regulations, including, but
not  limited  to, the 1940 Act, and Subchapter M of the Internal Revenue Code of
1986, as amended, (ii) the terms of this Agreement, (iii) the Fund's Articles of
Incorporation,  Bylaws  and Registration Statement as from time to time amended,
(iv)  relevant  undertakings  provided  to  State securities regulators, (v) the
stated  investment  objective,  policies  and restrictions of the Fund, and (vi)
such  other  guidelines  as  the Directors or Advisor may establish. The Advisor
shall  be  responsible  for  providing the Subadvisor with current copies of the
materials  specified in Subsections (a)(iii), (iv), (v) and (vi) of this Section
1.

     (b)  Social  Screening.  The  Subadvisor is responsible for screening those
investments  subject  to  social  screening ("Securities") to determine that the
Securities  meet  the  Fund's social investment criteria, as may be amended from
time  to  time  by  the Directors. The Subadvisor will buy only those Securities
which  have  been  determined  to  pass  the  Fund's  social  screens.

     (c)  Availability  of  Personnel.  The  Subadvisor at its expense will make
available  to  the  Directors  and  Advisor  at  reasonable  times its portfolio
managers  and  other  appropriate personnel, either in person, or, at the mutual
convenience  of the Advisor and the Subadvisor, by telephone, in order to review
the  Fund's  investment  policies  and to consult with the Directors and Advisor
regarding  the  Fund's  investment  affairs, including economic, statistical and
investment  matters  relevant  to  the  Subadvisor's  duties hereunder, and will
provide periodic reports to the Advisor relating to the investment strategies it
employs.

     (d) Expenses, Salaries and Facilities. The Subadvisor will pay all expenses
incurred  by  it  in  connection with its activities under this Agreement (other
than  the  cost  of  securities  and  other investments, including any brokerage
commissions),  including  but  not  limited  to,  all  salaries of personnel and
facilities  required  for  it  to  execute  its  duties  under  this  Agreement.

     (e)  Compliance  Reports.  The  Subadvisor  at its expense will provide the
Advisor with such compliance reports relating to its duties under this Agreement
as  may  be  agreed  upon  by  such  parties  from  time  to  time.

     (f)  Valuation.  The  Subadvisor  will  assist  the  Fund and its agents in
determining  whether  prices  obtained for valuation purposes accurately reflect
market  price  information  relating  to  the  assets  of the Fund for which the
Subadvisor  has responsibility on a daily basis (unless otherwise agreed upon by
the  parties  hereto)  and  at  such other times as the Advisor shall reasonably
request.

     (g)  Executing  Portfolio  Transactions.

     i)  Brokerage  In  selecting  brokers  and dealers to execute purchases and
sales  of  investments for the Fund, the Subadvisor will use its best efforts to
obtain  the most favorable price and execution available in accordance with this
paragraph. The Subadvisor agrees to provide the Advisor and the Fund with copies
of  its  policy  with respect to allocation of brokerage on trades for the Fund.
Subject  to  review by the Directors of appropriate policies and procedures, the
Subadvisor  may  cause  the  Fund  to pay a broker a commission, for effecting a
portfolio  transaction,  in  excess  of the commission another broker would have
charged  for  effecting  the  same  transaction.  If  the  first broker provided
brokerage  and/or  research  services,  including  statistical  data,  to  the
Subadvisor,  the  Subadvisor shall not be deemed to have acted unlawfully, or to
have breached any duly created by this Agreement, or otherwise, solely by reason
of  acting  according  to  such  authorization.

     ii)  Aggregate  Transactions  In  executing  portfolio transactions for the
Fund, the Subadvisor may, but will not be obligated to, aggregate the securities
to  be  sold or purchased with those of its other clients where such aggregation
is  not  inconsistent  with the policies of the Fund, to the extent permitted by
applicable laws and regulations. If the Subadvisor chooses to aggregate sales or
purchases,  it  will allocate the securities as well as the expenses incurred in
the  transaction  in  the  manner  it  considers  to  be  the most equitable and
consistent  with  its  fiduciary  obligations  to the Fund and its other clients
involved  in  the  transaction.

(iii)  Directed  Brokerage.  The  Advisor  may  direct  the  Subadvisor to use a
particular  broker  or  dealer for one or more trades if, in the sole opinion of
the  Advisor,  it  is  in  the  best  interest  of  the  Fund  to  do  so.

(iv)  Brokerage Accounts.  The Advisor authorizes and empowers the Subadvisor to
direct  the  Fund's  custodian  to  open  and  maintain  brokerage  accounts for
securities  and  other  property,  including financial and commodity futures and
commodities and options thereon (all such accounts hereinafter called "brokerage
accounts")  for  and  in the name of the Fund and to execute for the Fund as its
agent  and  attorney-in-fact  standard  customer  agreements with such broker or
brokers  as  the Subadvisor shall select as provided above.  The Subadvisor may,
using  such  of  the securities and other property in the Fund as the Subadvisor
deems  necessary  or  desirable,  direct the Fund's custodian to deposit for the
Fund original and maintenance brokerage and margin deposits and otherwise direct
payments  of  cash, cash equivalents and securities and other property into such
brokerage  accounts  and  to  such  brokers as the Subadvisor deems desirable or
appropriate.

     (h) Voting Proxies. The Subadvisor agrees to take appropriate action (which
may  include  voting)  on  all proxies for the Fund's portfolio investments in a
timely  manner.  Such  action  is  subject to the direction of the Directors and
Advisor  and  will  be consistent with the social screens and criteria governing
investment  selection  for  the  Fund.

     (i) Furnishing Information for the Fund's Proxies. The Subadvisor agrees to
provide the Advisor in a timely manner with all information necessary, including
the  Subadvisor's  certified  balance  sheet  and  information  concerning  the
Subadvisor's  controlling  persons,  for  preparation  of  the  Fund's  proxy
statements,  as  may  be  needed  from  time  to  time.

     2.     Books  and  Records.

a)  In connection with the purchase and sale of the Fund's portfolio securities,
the  Subadvisor  shall  arrange  for  the  transmission to the Fund's custodian,
and/or  the  Advisor  on  a daily basis, of such confirmations, trade tickets or
other  documentation  as  may  be necessary to enable the Advisor to perform its
accounting and administrative responsibilities with respect to the management of
the  Fund.

b)  Pursuant  to  Rule 31a-3 under the 1940 Act, Rule 204-2 under the Investment
Advisers  Act  of  1940  and  any  other  laws,  rules  or regulations regarding
recordkeeping,  the Subadvisor agrees that: (i) all records it maintains for the
Fund  are  the property of the Fund; (ii) it will surrender promptly to the Fund
or  Advisor any such records upon the Fund's or Advisor's request; (iii) it will
maintain  for  the  Fund the records that the Fund is required to maintain under
Rule  31a-1(b)  insofar  as such records relate to the investment affairs of the
Fund  for  which the Subadvisor has responsibility under this Agreement; (iv) it
will  preserve  for  the periods prescribed by Rule 31a-2 under the 1940 Act the
records  it maintains for the Fund; and (v) the Fund or Advisor will provide the
Subadvisor  with  a  copy of any records removed by the Fund or Advisor from the
location  of  the  Subadvisor.

c)  The Subadvisor represents that it has adopted a suitable Code of Ethics that
covers  its  activities  with  respect  to  its  services  to  the  Fund.

3.     Exclusivity.  Each party and its affiliates may have advisory, management
service  or  other agreements with other organizations and persons, and may have
other  interests and businesses; provided, however, that during the term of this
Agreement,  the  Subadvisor  will  not  provide  investment  advisory  services
("Services")  to  any  other  investment  company  registered under the 1940 Act
("Mutual  Fund")  investing  in  socially  screened  securities.

4.     Compensation. The Fund will pay to the Subadvisor as compensation for the
Subadvisor's  services rendered pursuant to this Agreement an annual Subadvisory
fee  as specified in one or more Schedules attached hereto and made part of this
Agreement.  Such  fees shall be paid by the Fund. Such fees shall be payable for
each  month  within  15  business  days  after  the  end  of  such month. If the
Subadvisor  shall  serve for less than the whole of a month, the compensation as
specified  shall  be  prorated.  The Schedules may be amended from time to time,
provided  that  amendments  are  made  in  conformity  with  applicable laws and
regulations and the Articles of Incorporation and Bylaws of the Fund. Any change
in the Schedule pertaining to any new or existing series of Calvert Impact Fund,
Inc.  shall  not  be deemed to affect the interest of any other series and shall
not  require  the  approval  of  shareholders  of  any  other  series.

5.     Assignment and Amendment of Agreement. This Agreement automatically shall
terminate  without  the payment of any penalty in the event of its assignment or
if  the  Investment  Advisory  Agreement  between the Advisor and the Fund shall
