                              FEBRUARY 1, 1996     
                  Ariel Appreciation Fund
                  Ariel Growth Fund
                  307 NORTH MICHIGAN AVENUE, SUITE 500, CHICAGO, ILLINOIS

The Ariel Appreciation Fund ("Appreciation Fund") and the Ariel Growth Fund
("Growth Fund") (collectively, the "Ariel Mutual Funds" or the "Funds") are
series of the Ariel Growth Fund (doing business as Ariel Investment Trust) (the
"Trust"). Ariel Capital Management, Inc. (the "Adviser") serves as the
investment adviser and service administrator for the Funds.     
   
INVESTMENT OBJECTIVES     
   
The investment objective of each Fund is to achieve long-term capital
appreciation by investing primarily in equity securities of issuers that in the
judgment of the Adviser are undervalued but demonstrate a strong potential for
growth. In seeking their objectives, the Funds attempt to discover relatively
unknown and undervalued companies, primarily through the Adviser's intensive
research. The Appreciation Fund focuses primarily on companies with market
capitalizations of approximately $200 million to $5 billion and emphasizes
medium sized companies. The Growth Fund invests principally in companies with
market capitalizations under $1.5 billion, with an emphasis on smaller
capitalization (small-cap) stocks.

</TABLE>    
                     
                  Explanation of Table: The purpose of the table is to assist
                  you in understanding the various costs and expenses that an
                  investor in the Funds would bear directly (shareholder
                  transaction costs) or indirectly (annual fund operating
                  expenses). The information is based on the Funds' expenses
                  for the fiscal year ended September 30, 1995.     
 
                  THE 5% RATE USED IN THE EXAMPLE IS ONLY FOR ILLUSTRATION AND
                  IS NOT INTENDED TO BE INDICATIVE OF THE FUTURE PERFORMANCE
                  OF THE FUNDS, WHICH MAY BE MORE OR LESS THAN THE ASSUMED
                  RATE. ACTUAL EXPENSES MAY BE MORE OR LESS THAN THOSE SHOWN.
 
                  (A) If you request a redemption by wire transfer, you will
                  be charged a $10 wire fee.
                     
                  (B) ANNUAL FUND OPERATING EXPENSES. Management Fees are
                  investment advisory and administrative fees which are paid
                  by each Fund to Ariel Capital Management, Inc. (the
                  "Adviser"). The Funds incur Other Expenses for maintaining
                  shareholder

                  records, furnishing shareholder statements and reports, and
                  other services. Management Fees and Other Expenses have
                  already been reflected in each Fund's share price and are
                  not charged directly to individual shareholder accounts.
                  Please refer to the section "Management and Organization of
                  the Funds" for further information.     
                     
                  Under the Rule 12b-1 plan, each Fund may pay fees of up to
                  0.30% of average net assets, but such fees are currently
                  limited by the Board of Trustees to 0.25% of average daily
                  net assets for the current fiscal year. The effect of a Rule
                  12b-1 plan is that in certain instances long-term
                  shareholders in the Funds may eventually pay more than the
                  economic equivalent of the maximum front-end sales charge
                  permitted by rules of the National Association of Securities
                  Dealers, Inc.     
                     
                  (C) THE ADVISER AGREES TO LIMIT CERTAIN EXPENSES. The
                  Adviser voluntarily agreed to absorb certain expenses of the
                  Funds during the fiscal year ended September 30, 1995. If
                  the Adviser had not done so, the Total Fund Operating
                  Expenses of the Appreciation Fund and Growth Fund would have
                  been 1.58% and 1.39%, respectively as reflected in the table
                  above. In addition, Management Fees would have represented
                  0.75% and 0.65% of the respective average daily net assets
                  of the Appreciation Fund and Growth Fund.     
 
                                                                               5

THE FUNDS SEEK    INVESTMENT OBJECTIVES AND POLICIES     
TO PROVIDE           
LONG-TERM         The investment objective of each Fund is to achieve long-
CAPITAL           term capital appreciation by investing primarily in equity
APPRECIATION.     securities of issuers that in the judgment of the Adviser
                  are undervalued but demonstrate a strong potential for
                  growth. In seeking their objectives, the Funds attempt to
                  discover relatively unknown and undervalued companies,
                  principally through the Adviser's own intensive research.
                      
                  THE APPRECIATION FUND focuses primarily on companies with
                  market capitalizations of approximately $200 million to $5
                  billion emphasizing medium sized companies.
 
                  THE GROWTH FUND invests principally in companies with market
                  capitalizations under $1.5 billion, with an emphasis on
                  smaller capitalization (small-cap) stocks.
                     
                  The Funds will take reasonable risks in seeking to achieve
                  their investment objectives. There is, of course, no
                  assurance that the Funds will be successful in meeting their
                  objectives since there is risk involved in the ownership of
                  securities.     
 
THE FUNDS         The Funds do not trade or time the market for quick gains;
FOLLOW A LONG-    rather, they follow a disciplined, conservative philosophy,
TERM              investing for long-term capital appreciation in securities
INVESTMENT        which appear to be undervalued relative to the market as a
PHILOSOPHY,       whole.
INVESTING
PRIMARILY IN
EQUITY
SECURITIES
WHICH APPEAR
TO BE
UNDERVALUED.
 
                  The Adviser looks for issuers that provide quality products
                  or services and which have not attracted significant
                  attention from securities analysts, institutional investors
                  and the media. In order to take advantage of the anticipated
                  growth of their portfolios, the Funds expect to hold
                  investments for a relatively long period. Occasionally,
                  however, securities purchased on a long-term basis may be
                  sold within 12 months after purchase in light of a change in
                  the circumstances of a particular company or industry, or in
                  general market or economic conditions. The Funds avoid
                  issuers in cyclical, commodity-based, start-up and recently
                  deregulated industries.
 
                                                                              11
<PAGE>
 
 
THE FUNDS LOOK    The Funds are interested in issuers with conservative
FOR ISSUERS       management and accounting and financial practices which have
WITH LONG-TERM    demonstrated long-term performance through various economic
PERFORMANCE       cycles. Such an issuer's balance sheet should show a
THROUGH           favorable cash position, limited debt and a reasonable
DIFFERENT         amount of working capital. The Adviser looks for equity
ECONOMIC          securities trading at a below average price-to-earnings
CYCLES.           ratio and a low price relative to the Adviser's evaluation
                  of expected sales and earnings growth, book value and
                  assets. The Funds are primarily interested in issuers which
                  have demonstrated high earnings-per-share growth potential
                  and the ability to achieve a high annual return on equity.
 
                  Although any investment in securities carries risk, the
                  conservative approach of the Ariel Mutual Funds is designed
                  to maximize growth in relation to the risks assumed. Since
                  the securities in which the Funds seek to invest may be less
                  actively traded than the securities of larger issuers, they
                  may not always participate in market rallies to the same
                  extent as more widely known securities. Conversely, these
                  securities may be expected to be somewhat less vulnerable
                  during market downturns. There is also somewhat less readily
                  available information concerning these securities. The
                  issuers of these securities tend to have a relatively higher
                  percentage of insider ownership.
 
THE FUNDS WILL    Although there is no predetermined percentage of assets to
NORMALLY          be invested in stocks, bonds or money market instruments,
INVEST AT         each Fund will normally invest at least 80% of the value of
LEAST 80% OF      its net assets in equity securities. Such securities will

THEIR             preferred stocks. The Funds may invest up to 20% of the
RESPECTIVE NET    value of their assets in bonds, other debt obligations or

EQUITY            for defensive or liquidity purposes or pending the
SECURITIES AND    investment of the proceeds from the sale of portfolio

TO 20% OF THE     repurchase agreements with recognized securities dealers and
VALUE OF THEIR    banks. If either Fund has assumed a temporary defensive

DEBT                 
OBLIGATIONS       Debt obligations in which the Funds invest may be long-term,
                  intermediate-term, short-term or any combination thereof,
                  depending on the Adviser's evaluation of current and
                  anticipated market patterns and trends. Such debt
                  obligations consist of the following: corporate obligations
                  which at the date of investment are rated within the four
                  highest grades established by Moody's Investors Services,
                  Inc. (Aaa, Aa, A, or Baa), or by Standard & Poor's
                  Corporation (AAA, AA, A, or BBB), or, if not rated, are of
                  comparable quality as determined by the Adviser (bonds rated
                  Baa or BBB are considered medium grade obligations and have
                  speculative characteristics); obligations issued or
                  guaranteed as to principal by the United States Government
                  or its agencies or instrumentalities ("U.S. Government
                  Securities"); certificates of deposits, and bankers'
                  acceptances of U.S. banks and their branches located outside
                  the U.S. and of U.S. branches of foreign banks, provided
                  that the bank has total assets of at least one billion
                  dollars or the equivalent in other currencies; commercial
                  paper which at the date of investment is rated A-2 or better
                  by Standard & Poor's, Prime-2 or better by Moody's or, if
                  not rated, is of comparable quality as determined by the
                  Adviser; and any of the above securities subject to
                  repurchase agreements with recognized securities dealers and
                  banks. In the event any debt obligation held by a Fund is
                  downgraded below the lowest permissible grade, the Fund is
                  not required to sell the security, but the Adviser will
                  consider the downgrade in determining whether to hold the
                  security. In any event, a Fund will not purchase or, if
                  downgraded, continue to hold debt obligations rated below
                  the lowest permissible grade if more than 5% of such Fund's
                  net assets would be invested in such debt obligations
                  (including, for the purpose of this limitation, convertible
                  debt securities rated below Baa or BBB, or if unrated, of
                  comparable quality).     
 
BORROWING         A Fund may not borrow money, except temporarily for
                  emergency purposes in an amount not exceeding 10% of total
                  assets in order to meet redemption requests without
                  immediately selling portfolio securities.
 
REPURCHASE        Repurchase agreements are arrangements under which a Fund
AGREEMENTS        buys securities and the seller simultaneously agrees to
                  repurchase the securities at a specified time and price. The
                  Funds may engage in repurchase agreements to earn a higher
                  rate of return than they could earn by investing in the
                  obligation which is the subject of the repurchase agreement.

                  order to minimize the risk of investing in repurchase
                  agreements, the Funds may engage in such transactions only
                  with recognized securities dealers and banks and in all
                  instances must hold underlying securities with a value at
                  least equal to the total repurchase price such dealer or
                  bank has agreed to pay.
 
ILLIQUID          The Funds will not make purchases of illiquid securities
SECURITIES        (including entering into repurchase agreements for periods
                  longer than seven days) if such a purchase would cause more
                  than 10% of the Growth Fund's total assets, or 5% of the
                  Appreciation Fund's total assets, to be invested in such
                  securities.

THE FUNDS            
FOLLOW A          The Funds currently observe the following operating
POLICY OF         policies, which may be changed by the Board of Trustees: (1)
RESPONSIBLE       the Adviser actively seeks companies that achieve excellence
INVESTING.        in both financial return and environmental soundness,
                  selecting issuers that take positive steps toward preserving
                  our environment and avoiding companies with poor
                  environmental records; (2) a Fund will not make investments
                  in issuers whose primary source of revenue derives from the
                  production of tobacco products; and (3) a Fund will not
                  invest in issuers primarily engaged in the manufacture of
                  weapons systems, the production of nuclear energy, or the
                  manufacture of equipment to produce nuclear energy.     
                     
                  The Funds have engaged the services of Franklin Research and
                  Development Corporation of Boston to provide environmental
                  screening for all issuers selected for the Funds. Franklin
                  provides information and opinions on the companies'
                  environmental histories. However, Franklin does not make

                  purchase or sale of securities.     
 
                  The Adviser believes that there are long-term benefits
                  inherent in an investment philosophy that demonstrates
                  concern for human rights, economic priorities and
                  international relations.

                  DISTRIBUTION PLAN
                  The Funds bear some of the costs of selling their shares
                  under a Distribution Plan adopted pursuant to Rule 12b-1
                  under the 1940 Act (the Plan). The Plan authorizes payments
                  by the Funds of up to 0.30% annually of each Fund's average
                  daily net asset value, but payments under the Plan are
                  currently limited by the Board of Trustees to 0.25% annually
                  of such average daily net asset value.

                  completed and signed application is required for each new

                  making your initial investment. An account application
                  accompanies this prospectus. Additional forms may be
                  required from corporations, associations and certain
                  financial institutions. If you have any questions or need

                  NET ASSET VALUE
                  Net asset value per share ("NAV") refers to the worth of one
                  share. NAV is computed by adding the value of all portfolio
                  holdings, plus other assets, deducting liabilities and then
                  dividing the result by the number of shares outstanding. A
                  Fund's NAV will vary daily based on the market values of its
                  investments.
 
                  Portfolio securities and other assets are valued based on
                  market quotations, except that debt securities maturing
                  within 60 days are valued at amortized cost, which
                  approximates market value. If quotations for a security are
                  not readily available, the security is valued by a method
                  that the Board of Trustees believes accurately reflects fair
                  value.
 
                  The NAV is calculated at the close of the regular session of
                  the New York Stock Exchange (normally 3:00 p.m. Central
                  time). The Funds are open for business each day the New York
                  Stock Exchange is open. All purchases of Fund shares will be
                  confirmed and credited to your account in full and
                  fractional shares.

                  by check, the Funds can hold payment on redemptions until
                  they are reasonably satisfied that the investment is
                  collected (normally 15 calendar days). To avoid this
                  collection period, you can wire federal funds from your
                  bank, which may charge you a fee.
                     
                  Certain financial institutions or broker-dealers which have
                  entered into a sales agreement with the Distributor may
                  enter confirmed purchase orders on behalf of customers by
                  phone, with payment to follow within a number of days of the
                  order as specified by the program. If payment is not
                  received in the time specified, the financial institution or
                  broker-dealer could be liable for resulting fees or losses.
                  State securities laws may require financial institutions
                  such as banks to be licensed as securities dealers in order

                  OTHER INFORMATION ABOUT PURCHASING SHARES
                     
                  Although there is generally no sales charge when you
                  purchase shares, certain dealers or financial institutions
                  which sell shares of Ariel Mutual Funds may impose charges
                  for their services, and such charges may constitute a
                  significant portion of a smaller account.     
                     
                  The Funds do not issue share certificates unless you
                  specifically request one each time you make a purchase.
                  Certificates are not issued for fractional shares or to
                  shareholders who have elected a systematic withdrawal plan.
                  Also, shares represented by certificates may not be redeemed
                  by telephone. See "Redeeming Shares" for information on how
                  to redeem your shares.

                  also make exchanges by calling 1-800-29-ARIEL (1-800-292-

                  All accounts opened as a result of using the exchange

                  Because of the time needed to transfer money between funds,
                  you may not exchange into and out of the same fund on the
                  same or successive days; there must be at least one day
                  between exchanges. You may exchange your shares of the Funds
                  only for shares that have been registered for sale in your
                  state.
 
                  Remember that each exchange represents the sale of shares of
                  one fund and the purchase of shares of another. Therefore,
                  you could realize a taxable gain or loss on the transaction.
 
                  The Funds reserve the right to terminate or modify the
                  exchange privilege with 60 days' written notice. If your
                  account is subject to backup withholding, you may not use
                  the exchange privilege.
                     
                  Because excessive trading can hurt the Funds' performance
                  and shareholders, the Funds also reserve the right to
                  temporarily or permanently terminate, with or without
                  advance notice, the exchange privilege of any investor who
                  makes excessive use of the exchange privilege (e.g. more
                  than five exchanges per calendar year). Your exchanges may
                  be restricted or refused if a Fund receives or anticipates
                  simultaneous orders affecting significant portions of its
                  assets. In particular, a pattern of exchanges with a "market
                  timer" strategy may be disruptive to the Funds.     
                     
                  If you have any share certificates, you must include them
                  with your exchange request. A signature guarantee is not
                  required except in cases where shares are also redeemed at
                  the same time for cash in an amount exceeding $25,000. For
                  certificate delivery instructions see "Redeeming Shares By

                  TELEPHONE TRANSACTIONS
                     
                  If you have telephone transaction privileges, you may redeem
                  or exchange shares or wire funds by telephone as described
                  in this prospectus. You automatically have telephone
                  privileges unless you elect otherwise. These privileges,
                  however, may not be available through certain dealers and
                  financial institutions. By exercising the telephone
                  privilege to sell or exchange shares, you agree that the
                  Funds shall not be liable for following telephone
                  instructions reasonably believed to be genuine. Reasonable
                  procedures will be employed to confirm     
 
                                                                              25

                  that such instructions are genuine and, if not employed, the
                  Funds may be liable for unauthorized instructions. Such
                  procedures will include a request for a personal
                  identification number and tape recording of the
                  instructions. You should verify the accuracy of telephone
                  transactions immediately upon receipt of your confirmation
                  statement.     
 
                  During unusual market conditions, we may have difficulty in
                  accepting telephone requests, in which case you should mail
                  your request. The Funds reserve the right to terminate,
                  suspend or modify telephone transaction privileges.
 
                  SIGNATURE GUARANTEES
WE MAY REQUIRE    For our mutual protection, we may require a signature
SIGNATURE         guarantee on certain transaction requests. A signature
GUARANTEES.       guarantee verifies the authenticity of your signature, and
                  may be obtained from any bank, trust company, savings and
                  loan association, credit union, broker-dealer firm or member
                  of a domestic stock exchange. A signature guarantee cannot
                  be provided by a notary public. If redemption proceeds are
                  $25,000 or less and are to be paid or credited to an
                  individual shareholder of record at the address of record, a
                  signature guarantee is not required (unless there has been
                  an address change within 60 days). All other redemption
                  requests must have signatures guaranteed.
 
                  SPECIAL SERVICES AND CHARGES
                  The Funds pay for shareholder services but not for special
                  services that are required by a few shareholders, such as a
                  request for a historical transcript of an account. You may
                  be required to pay a research fee for these special
                  services.
 
                  If you are purchasing shares of a Fund through a program of
                  services offered by a broker-dealer or financial
                  institution, you should read the program materials in
                  conjunction with this prospectus. Certain features may be
                  modified in these programs, and administrative charges may
                  be imposed by the broker-dealer or financial institution for
                  the services rendered.
 
                  REDEEMING SHARES

                  shares or dollar amount and where you want your check to be

                  to our Transfer Agent as follows:
 
                           Ariel Mutual Funds
                           P.O. Box 419121
                           Kansas City, Missouri 64141-6121
                     
                  Certain shareholders, such as corporations, trusts and
                  estates, may be required to submit additional documents. The
                  letter of instruction must be signed by all required
                  authorized signers. If you want your money to be wired to a
                  bank not previously authorized or if you would like funds
                  sent to a different address or another person, your letter
                  must be signature guaranteed. Please remember that you
                  cannot place any conditions on your request. If any share
                  certificates were issued, they must be returned duly
                  endorsed or accompanied by a separate stock assignment. See
                  "Signature Guarantees."     
 
BY TELEPHONE      Unless you have elected not to have telephone transaction
                  privileges by checking the box in your application, you may
                  also redeem shares by calling 1-800-29-ARIEL (1-800-292-
                  7435) and receive a check by mail. Remember, however, that
                  the check can only be issued for up to $25,000, and only to
                  the registered owner (who must be an individual), and may
                  only be sent to the address of record, which must have been
                  on file for at least 60 days. Shares represented by
                  certificates may not be redeemed by telephone.
 
BY WIRE           Payment for your shares may also be made to you by wire if
                  you have selected this option in your application and have
                  named a commercial bank or savings institution with a
                  routing number to which we can send your money.
 
                  Once you have applied for wire redemption privileges, you or
                  any other person can make such a request by calling 1-800-
                  29-ARIEL (1-800-292-7435). You may also use your wire
                  privilege by mailing a signed request that includes the name
                  of the Fund, account number and amount you wish to have
                  wired, by writing to:
 
                           Ariel Mutual Funds
                           P.O. Box 419121
                           Kansas City, Missouri 64141-6121
 
                                                                              27

                  The proceeds will be sent only to the financial institution
                  you have designated on your application. You may terminate
                  the wire redemption privilege by notifying us in writing. A
                  charge of $10 is imposed on wire redemptions. See the
                  restrictions under "Telephone Transactions" as they also
                  apply to wire redemptions.     
 
SYSTEMATIC           
CHECK             If you maintain an account with a balance of $10,000 or
REDEMPTIONS       more, you may have regular monthly or quarterly redemption
                  checks for a fixed amount sent to you simply by sending a
                  letter with all the information, including the Fund name,
                  your account number, the dollar amount ($100 minimum) and
                  when you want the checks mailed to your address on the
                  account. If you would like checks regularly mailed to
                  another person or place, the signature on your letter must
                  be guaranteed. See "Signature Guarantees."     
 
                  OTHER INFORMATION ABOUT REDEMPTIONS
TO ENSURE         Other than the $10 fee imposed on wire redemptions, there is
ACCEPTANCE OF     no charge for redeeming your shares. If, however, you redeem

PLEASE FOLLOW
THE PROCEDURES
DESCRIBED HERE
AND BELOW.
                     
                  Once your shares are redeemed, the proceeds will normally be
                  sent to you on the next business day. However, if making
                  immediate payment could adversely affect the Fund, it may
                  take up to seven calendar days. Redemptions may be suspended
                  or payment dates postponed when (i) the New York Stock
                  Exchange is closed (or when trading is restricted) for any
                  reason other than its customary weekend or holiday closing;
                  (ii) an emergency exists as a result of which (A) disposal
                  by a Fund of securities owned by it is not reasonably
                  practical or (B) it is not reasonably practical for a Fund
                  fairly to determine the value of its net assets; or (iii)
                  under any emergency circumstances as determined by the
                  Securities and Exchange Commission.     
 
                  You may redeem all or a portion of your shares on any
                  business day during which the New York Stock Exchange is
                  open for business. Your shares will be redeemed at the net
                  asset value next calculated after your redemption request is
                  received by the Transfer Agent in proper form. Redemptions
                  made after the New York Stock Exchange has closed will be
                  made at the next
 
28
<PAGE>
 
                  day's net asset value. Remember that, if you redeem shortly
                  after purchasing shares, the Funds may hold payment on the
                  redemption of your shares until they are reasonably
                  satisfied that payments made by check have been collected
                  (normally up to 15 calendar days after investment).
 
MINIMUM           Please maintain a balance in your account of at least
ACCOUNT           $1,000. If, due to redemptions, the value of your account in
BALANCE IS        a Fund falls below $1,000, or you fail to invest at least
$1,000.           $1,000, the account may be closed and the proceeds mailed to
                  you at your address of record. You will be given 30 days'
                  notice that your account will be closed unless you make an
                  additional investment to increase your account balance to
                  the $1,000 minimum.

                  Tax Identification Number ("TIN") and a signed certified
                  application or Form W-9, Federal law requires the Funds to
                  withhold 31% of your dividends and certain redemptions. In
                  addition, you may be subject to a fine. You will also be
                  prohibited from opening another account by exchange. If this
                  TIN information is not received within 60 days after your
                  account is established, your account may be redeemed at the
                  current NAV on the date of redemption. The Funds reserve the
                  right to reject any new account or any purchase order for
                  failure to supply a certified TIN.

                            INVESTMENT RESTRICTIONS

The Trust has adopted the following investment restrictions as fundamental
policies. These restrictions cannot be changed as to a Fund without the approval
of the holders of a majority of the outstanding shares of the Fund. As defined
in the Investment Company Act of 1940, this means the lesser of the vote of (a)
67% of the shares of the Fund at a meeting where more than 50% of the
outstanding shares are present in person or by proxy, or (b) more than 50% of
the outstanding shares of the Fund. Shares have equal rights as to voting.

A Fund may not:
    
  (1) Purchase securities of any issuer (other than obligations issued, or
  guaranteed by, the United States Government, its agencies or
  instrumentalities) if, as a result, more than 5% of the value of the Fund's
  total assets would be invested in securities of such issuer.      

  (2) Concentrate more than 25% of the value of its total assets in any one
  industry; provided, however, that there is no limitation with respect to
  investments in obligations issued or guaranteed by the United States
  Government or its agencies and instrumentalities.

  (3) Purchase more than 10% of the outstanding voting securities of any issuer.

  (4) Make loans (other than loans of its portfolio securities, loans through
  the purchase of money market instruments and repurchase agreements, or loans
  through the purchase of bonds, debentures or other debt securities of the
  types commonly offered privately and purchased by financial institutions). The
  purchase of a portion of an issue of publicly distributed debt obligations
  shall not constitute the making of loans. (See also "Additional Information
  about Lending Securities and Repurchase Agreements -- Loans of Portfolio
  Securities.")

  (5) Underwrite the securities of other issuers.

  (6) Purchase securities which are subject to legal or contractual restrictions
  on resale or for which there is no readily available market or which are
  repurchase agreements not terminable within seven days if at the time of
  purchase more than 5% of the Appreciation Fund's total assets or 10% of the
  Growth Fund's total assets would be so invested.

  (7) Purchase from or sell to any of the Fund's officers or trustees, or firms
  of which any of them are members, any securities (other than capital stock of
  the Fund), but such persons or firms may act as brokers for the Fund for
  customary commissions.

  (8) Issue senior securities or borrow money, except from banks as a temporary
  measure for extraordinary or emergency purposes and then only in an amount up
  to 10% of the value of its total assets in order to meet redemption requests
  without immediately selling portfolio securities. In order to secure any such
  bank borrowings under this section, the Fund may pledge, mortgage or
  hypothecate the Fund's assets and then in an amount not greater than 15% of
  the value of its total assets. The Fund will not borrow for leverage purposes
  and investment securities will not be purchased while any borrowings are
  outstanding.

  (9) Make short sales of securities, purchase any securities on margin, or
  invest in warrants or commodities.

  (10) Write, purchase or sell puts, calls, straddles or spreads, or
  combinations thereof.
    
  (11) Purchase or retain the securities of any issuer if any officer or trustee
  of the Fund or its investment adviser owns beneficially more than  1/2 of 1%
  of the securities of such issuer and if together such individuals own more
  than 5% of the securities of such issuer.      

  (12) Invest for the purpose of exercising control or management of another
  issuer.

                                       2
<PAGE>
 
  (13) Invest in real estate or real estate limited partnerships, although it
  may invest in securities which are secured by real estate or real estate
  mortgages and may invest in the securities of issuers which invest or deal in
  commodities, commodity futures, real estate or real estate mortgages.

  (14) Invest in interests in oil, gas, or other mineral exploration or
  development programs, although it may invest in securities of issuers which
  invest in or sponsor such programs.

  (15) Purchase the securities of other investment companies, except as they may
  be acquired as part of a merger, consolidation or acquisition of assets.

  (16) Purchase the securities of companies which have a record of less than
  three years' continuous operation if, as a result, more than 5% of the value
  of the Fund's assets would be invested in securities of such issuer.

  (17) Engage in arbitrage transactions.

  Restrictions apply as of the time of the transaction entered into by a Fund
  without regard to later changes in the value of any portfolio security or the
  assets of the Fund.


                          ADDITIONAL INFORMATION ABOUT
                  LENDING SECURITIES AND REPURCHASE AGREEMENTS

LOANS OF PORTFOLIO SECURITIES

Securities of a Fund may be lent to member firms of the New York Stock Exchange
and commercial banks with assets of one billion dollars or more. Any such loans
must be secured continuously in the form of cash or cash equivalents, such as
U.S. Treasury bills. The amount of the collateral must, on a current basis,
equal or exceed the market value of the loaned securities, and must be
terminable upon notice, at any time. The Trust will exercise its right to
terminate a securities loan in order to preserve its right to vote upon matters
of importance affecting holders of the securities. A Fund may make a securities
loan if the value of the securities loaned from the Fund will not exceed 10% of
the Fund's assets. However, as a matter of non-fundamental policy, such loan is
not made if it would cause more than 5% of net assets of a Fund to be subject to
such loans.

The advantage of such loans would be that the Fund continues to receive the
equivalent of the interest earned or dividends paid by the issuer on the loaned
securities while at the same time earning interest on the cash or equivalent
collateral.

Securities loans would be made to broker-dealers and other financial
institutions to facilitate their deliveries of such securities. As with any
extension of credit there may be risks of delay in recovery and possibly loss of
rights in the loaned securities should the borrower of the loaned securities
fail financially. However, loans will be made only to those firms that Ariel
Capital Management, Inc. (the "Adviser") deems creditworthy and only on such
terms as the Adviser believes should compensate for such risk. On termination of
the loan the borrower is obligated to return the securities to the Fund; any
gain or loss in the market value of the security during the loan period will
inure to the Fund. Custodial fees may be paid in connection with the loan.


REPURCHASE AGREEMENTS

A Fund may purchase securities subject to repurchase agreements. Repurchase
agreements are transactions in which a person purchases a security and
simultaneously commits to resell that security to the seller at a mutually
agreed upon time and price. The seller's obligation is secured by the underlying
security. The repurchase price reflects the initial purchase price plus an
agreed upon market rate of interest. While the underlying security may bear a
maturity in excess of one year, the term of the repurchase agreement is always
less than one year. Repurchase agreements not terminable within seven days will
be limited 

                                       3
<PAGE>
 
to no more than 5% of a Fund's assets. Repurchase agreements are short-term
money market investments, designed to generate current income.

A Fund will only engage in repurchase agreements with recognized securities
dealers and banks determined to present minimal credit risk by the Adviser.

A Fund will only engage in repurchase agreements reasonably designed to secure
fully, during the term of the agreement, the seller's obligation to repurchase
the underlying security and will monitor the market value of the underlying
security during the term of the agreement. If the value of the underlying
security declines and is not at least equal to the repurchase price due to the
Fund pursuant to the agreement, the Fund will require the seller to pledge
additional securities or cash to secure the seller's obligations pursuant to the
agreement. If the seller defaults on its obligation to repurchase and the value
of the underlying security declines, the Fund may incur a loss and may incur
expenses in selling the underlying security.


                       DIVIDENDS, DISTRIBUTIONS AND TAXES
    
Each Fund's dividends, if any, are declared and paid from net investment income
on an annual basis. Generally, net investment income consists of the interest
income earned (adjusted for amortization of original issue or market discounts
or premiums) and dividends declared and received on investments, less expenses.
Distributions of net capital gains, if any, are generally declared and paid by
each Fund annually; however, the Funds do not intend to make any such
distributions from net capital gains unless available capital loss carryovers,
if any, have been used or have expired.      

Generally, dividends (including short-term capital gains) and distributions are
taxable to the shareholder in the year they are paid. However, any dividends and
distributions paid in January but declared during the prior three months are
taxable in the year declared.

The Trust is required to withhold 31% of any dividends (including long-term
capital gain dividends) paid and 31% of each redemption transaction, if: (a) the
shareholder's social security number or other taxpayer identification number
("TIN") is not provided or an obviously incorrect TIN is provided; (b) the
shareholder does not certify under penalties of perjury that the TIN provided is
the shareholder's correct TIN and that the shareholder is not subject to backup
withholding under section 3406(a)(1)(C) of the Internal Revenue Code because of
underreporting (however, failure to provide certification as to the application
of section 3406(a)(1)(C) will result only in backup withholding on dividends,
not on redemptions); or (c) the Fund is notified by the Internal Revenue Service
that the TIN provided by the shareholder is incorrect or that there has been
underreporting of interest or dividends by the shareholder. Affected
shareholders will receive statements at least annually specifying the amount
withheld.

In addition, the Trust is required under the broker reporting provisions of the
Code to report to the Internal Revenue Service the following information with
respect to each redemption transaction: (a) the shareholder's name, address,
account number and taxpayer identification number; (b) the total dollar value of
the redemptions; and (c) each Fund's identifying CUSIP number.

Certain shareholders are, however, exempt from the backup withholding and broker
reporting requirements. Exempt shareholders include: corporations; financial
institutions; tax-exempt organizations; individual retirement plans; the U.S., a
State, the District of Columbia, a U.S. possession, a foreign government, an
international organization, or any political subdivision, agency or
instrumentality of any of the foregoing; U.S. registered commodities or
securities dealers; real estate investment trusts; registered investment
companies; bank common trust funds; certain charitable trusts; foreign central
banks of issue. Non-resident aliens also are generally not subject to either
requirement but, along with certain foreign partnerships and foreign
corporations, may instead be subject to withholding under Section 1441 of the
Code. Shareholders claiming exemption from backup withholding and broker
reporting should call or write the Trust for further information.

                                       4

The Trust intends to operate each Fund to qualify as a "regulated investment
company" under Subchapter M of the Code. By so qualifying, a Fund will not be
subject to federal income taxes to the extent its earnings are distributed. The
Trust also intends to manage the Funds so they are not subject to the excise tax
imposed by the Tax Reform Act of 1986 (the "Act").


                          CALCULATION OF TOTAL RETURN

A Fund's "total return" may be advertised from time to time. Total return for a
period is the percentage change in value during the period of an investment in
shares of a Fund, including all additional shares purchased within the period
with reinvested dividends and distributions. Average annual total return is the
average annual compounded rate of change in value represented by the total
return for the period.

Average annual total return is computed according to the following formula:

                               P(1 + T)/n/ = ERV

where P = the amount of an assumed initial investment in shares of a Fund (less
the maximum sales charge, if any, during the period); T = average annual total
return; n = the number of years from initial investment to the end of the
period; and ERV = the ending redeemable value of shares held at the end of the
period.

Average Annual total return for each of the Fund's shares for the periods
indicated are as follows:

</TABLE>      

Total return may be advertised for other periods, such as by quarter, or
cumulatively for more than one year.

Total return, like net asset value per share, fluctuates in response to changes
in market conditions. Performance for any particular time period is historical
in nature and is not intended and should not be considered to be an indication
of future return.

                                NET ASSET VALUE
    
The net asset value per share of a Fund, the price at which the Fund's shares
are purchased and redeemed, is determined every business day as of the close of
the New York Stock Exchange (generally 3:00 p.m., Central time), and at such
other times as may be necessary or appropriate. The Funds do not determine net
asset value on certain      

                                       5
<PAGE>
 
national holidays or other days on which the New York Stock Exchange is closed:
New Year's Day, Good Friday, Memorial Day, Independence Day, Labor Day,
Thanksgiving Day and Christmas Day.
    
The net asset value per share is computed by dividing the value of a Fund's
total assets, less its liabilities, by the total number of shares outstanding.
The Funds' securities are valued as follows: (a) securities for which market
quotations are readily available are valued at the most recent closing price.
All other securities for which reliable bid quotations are available are valued
at the mean between the bid and asked price, or yield equivalent as obtained
from one or more market makers for such securities; (b) securities maturing
within 60 days are valued at cost, plus or minus any amortized discount or
premium, unless the Board of Trustees determines such method not to be
appropriate under the circumstances; and (c) all other securities and assets for
which market quotations are not readily available are fairly valued by the
Adviser in good faith under the supervision of the Board of Trustees.      


                 INVESTMENT ADVISER AND SERVICES ADMINISTRATOR

Ariel Capital Management, Inc. (the "Adviser"), 307 North Michigan Avenue, Suite
500, Chicago, Illinois 60601, which is controlled by John W. Rogers, Jr., acts
as investment adviser and services administrator under a management agreement
with the Trust ("Management Agreement").

The Management Agreement between the Trust and the Adviser will remain in effect
as to a Fund indefinitely, provided continuance is approved at least annually by
vote of the holders of a majority of the outstanding shares of the Fund or by
the Board of Trustees of the Trust; and further provided that such continuance
is also approved annually by the vote of a majority of the Trustees of the Trust
who are not parties to the Agreement or interested persons of parties to the
Agreement or interested persons of such parties, cast in person at a meeting
called for the purpose of voting on such approval. The Management Agreement may
be terminated without penalty by the Trust or the Adviser upon 60 days' prior
written notice; it automatically terminates in the event of its assignment.

Pursuant to the Management Agreement, the Adviser is responsible for determining
the investment selections for a Fund in accordance with the Fund's investment
objectives and policies stated above, subject to the direction and control of
the Board of Trustees. The Adviser pays the salaries and fees of all officers
and Trustees who are affiliated persons of the Adviser.

The Adviser also serves as the Funds' services administrator with the Trust.
Pursuant to the Management Agreement, the Adviser provides the Funds with office
space, administrative services, furnishes executive and other personnel to the
Funds and is responsible for providing or overseeing the Fund's day-to-day
management and administration.
    
The Funds pay all operating expenses not expressly assumed by the Adviser,
including custodial and transfer agency fees, federal and state securities
registration fees, legal and audit fees, and brokerage commissions and other
costs associated with the purchase and sale of portfolio securities, except that
the Adviser must reimburse a Fund if its annual expenses (excluding brokerage,
taxes, interest, Distribution Plan expenses and extraordinary items) exceed
1.50% of the first $30 million of each Fund's average daily net assets and 1% of
such assets in excess of $30 million.      
    
The fees paid to the Adviser for the fiscal periods ended September 30, 1993 and
1994  were $465,276, and 575,622, respectively, for the Appreciation Fund and
$608,382 and $549,007, respectively, for the Growth Fund.      
    
Until September 6, 1994 there was a different services administrator which
received for the fiscal year ended September 30, 1993 and the period ended
September 5, 1994, $930,169 and $987,802, respectively, for the Appreciation
Fund and $973,413 and $769,661, respectively for the Growth Fund.
Reimbursements were made by such administrator to the Appreciation Fund during
these periods of $0 and      

                                       6
<PAGE>
 
$88,239, respectively. The Adviser reimbursed the Appreciation Fund $16,101 for
the period from September 6, 1994 to September 30, 1994.
    
In 1995, the investment advisory and services administration agreements were
combined into one Management Agreement.  Fees paid to the Adviser for the fiscal
year ended September 30, 1995 under the Management Agreement (including amounts
received under the old investment advisory agreement) were $1,050,040 and
$865,718, for the Appreciation Fund and the Growth Fund, respectively.  The
Adviser reimbursed the Appreciation Fund $303,795 and the Growth Fund $33,526,
for the same period.      
    
In connection with the exchange privilege with respect to Cash Resource Money
Market Fund, Cash Resource U.S. Government Money Market Fund and Cash Resource
Tax-Exempt Money Market Fund, the Distributor acts as a shareholder servicing
agent. For its services, the Distributor receives a fee from each such fund at
the rate of 0.25% of the average net assets of each account in such funds
established through the use of the exchange privilege pursuant to a Rule 12b-1
distribution plan adopted by Cash Resource Money Market Fund, Cash Resource U.S.
Government Money Market Fund and Cash Resource Tax-Exempt Money Market Fund.
     

The Adviser has adopted a Code of Ethics which regulates the personal securities
transactions of the Adviser's investment personnel and other employees and
affiliates with access to information regarding securities transactions of the
Fund. The Code of Ethics requires investment personnel to disclose all personal
securities holdings upon commencement of employment and all subsequent trading
activity to the Adviser's Compliance Officer. Investment personnel are
prohibited from engaging in any securities transactions, including the purchase
of securities in a private offering, without the prior consent of the Compliance
Officer. Additionally, such personnel are prohibited from purchasing securities
in an initial public offering and are prohibited from trading in any securities
(i) for which either Fund has a pending buy or sell order, (ii) which either
Fund is considering buying or selling, or (iii) which either Fund purchased or
sold within seven calendar days.


                             METHOD OF DISTRIBUTION
    
Ariel Distributors, Inc., an affiliate of the Adviser, is the principal
underwriter for the Funds under an agreement with the Trust. Pursuant to the
Underwriting Agreement, Ariel Distributors receives a fee at the annual rate of
0.25% of each Fund's average daily net assets for its distribution services and
for assuming certain marketing expenses. Ariel Distributors is located at 307 N.
Michigan Avenue, Chicago, Illinois 60601. Prior to ________, 1995, the Adviser
served as the principal underwriter.      
    
The Trust has also adopted a Distribution Plan pursuant to Rule 12b-1 under the
Investment Company Act of 1940 with respect to the Funds (the "Distribution
Plan"). Rule 12b-1 permits an investment company to finance, directly or
indirectly, any activity which is primarily intended to result in the sale of
its shares only if it does so in accordance with the provisions of such Rule.
The Distribution Plan authorizes the Trust to pay up to 0.30% annually of a
Fund's average daily net assets in connection with the distribution of the
Fund's shares. Consistent with the Underwriting Agreement, however, payments
under the Distribution Plan are currently limited by the Board of Trustees to
0.25% annually of such average daily net assets.      
    
During the fiscal year ended September 30, 1995, the Appreciation Fund and
Growth Fund paid Distribution Plan expenses of $350,140 and $332,968,
respectively, to the principal underwriter. Of the total amounts paid $368,724
was used to pay broker-dealers for their distribution and maintenance services
and $314,384 was used for advertising, shareholder account maintenance, printing
and related costs.      

                                       7
<PAGE>
 
The Distribution Plan was approved by the Board of Trustees, including the
Trustees who are not "interested persons" of the Fund (as that term is defined
in the Investment Company Act of 1940) and who have no direct financial interest
in the operation of the Plan or in any agreements related to the Distribution
Plan (the "Independent Trustees"). The selection and nomination of the
Independent Trustees is committed to the discretion of such Independent
Trustees. In establishing the Distribution Plan, the Trustees considered various
factors including the amount of the distribution fee. The Trustees determined
that there is a reasonable likelihood that the Distribution Plan will benefit
the Trust and its shareholders.

The Distribution Plan may be terminated as to a Fund by vote of a majority of
the Independent Trustees, or by vote of a majority of the outstanding shares of
the Fund. Any change in the Distribution Plan that would materially increase the
distribution cost to a Fund requires approval of the shareholders of that Fund;
otherwise, the Distribution Plan may be amended by the Trustees, including a
majority of the Independent Trustees.

The Distribution Plan will continue in effect indefinitely, if not terminated in
accordance with its terms, provided that such continuance is annually approved
by (i) the vote of a majority of the Independent Trustees and (ii) the vote of a
majority of the entire Board of Trustees.

Apart from the Distribution Plan, the Adviser, at its expense, may incur costs
and pay expenses associated with the distribution of shares of the Fund,
including compensation to broker-dealers in consideration of promotional or
administrative services.


                          TRANSFER AGENT AND CUSTODIAN

Investors Fiduciary Trust Company ("IFTC") has been retained by the Trust to act
as transfer agent, custodian, dividend disbursing agent and shareholder
servicing agent. These responsibilities include: responding to shareholder
inquiries and instructions concerning their accounts; crediting and debiting
shareholder accounts for purchases and redemptions of Fund shares and confirming
such transactions; updating of shareholder accounts to reflect declaration and
payment of dividends; keeping custody of all of the Funds' investments; and
preparing and distributing quarterly statements to shareholders regarding their
accounts.

                             PORTFOLIO TRANSACTIONS

Portfolio transactions are undertaken on the basis of their desirability from an
investment standpoint. Investment decisions and choice of brokers and dealers
are made by the Adviser under the direction and supervision of the Trust's Board
of Trustees.

The Trust seeks to obtain the best price and most favorable execution and
selects broker-dealers on the basis of their professional capability and the
value and quality of their services. Broker-dealers that provide the Trust with
statistical, research, or other information and services may be selected. Such
broker-dealers may receive compensation for executing portfolio transactions
that is in excess of the compensation another broker-dealer would have received
for executing such transactions, if the Adviser determines in good faith that
such compensation is reasonable in relation to the value of the information and
services provided. Research services furnished by investment firms may be
utilized by the Adviser in connection with its investment services for other
accounts; likewise, research services provided by investment firms used for
other accounts may be utilized by the Adviser in performing its services for the
Trust. Although any statistical, research, or other information or services
provided by broker-dealers may be useful to the Adviser, its dollar value is
generally indeterminable and its availability or receipt does not materially
reduce the Adviser's normal research activities or expenses.

The Adviser may also execute Fund transactions with or through broker-dealers
who have sold shares of the Funds. However, such sales will not be a qualifying
or disqualifying factor in a broker-dealer's selection nor will the selection of
any broker-dealer be based on the volume of Fund shares sold.

                              INDEPENDENT AUDITORS

The Funds' independent auditors, Ernst & Young LLP, 233 South Wacker Drive,
Chicago, IL 60606, audit and report on the Funds' annual financial statements,
review certain regulatory reports and the Funds' federal income tax returns, and
perform other professional accounting, auditing, tax and advisory services when
engaged to do so by the Funds. Shareholders will receive annual audited
financial statements and semi-annual unaudited financial statements.


                              GENERAL INFORMATION

The Ariel Growth Fund and the Ariel Appreciation Fund are series of Ariel Growth
Fund (doing business as Ariel Investment Trust), an open-end, diversified
management investment company organized as a serial Massachusetts business trust
on April 1, 1986. The Declaration of Trust contains an express disclaimer of
shareholder liability for acts or obligations of the Trust. The shareholders of
a Massachusetts business trust might, however, under certain circumstances, be
held personally liable as partners for its obligations. The Declaration of Trust
provides for indemnification and reimbursement of expenses out of Trust assets
for any shareholder held personally liable for obligations of the Trust. The
Declaration of Trust further provides that the Trust may maintain appropriate
insurance (for example, fidelity bonding and errors and omissions insurance) for
the protection of the Trust, its shareholders, trustees, officers, employees and
agents to cover possible tort and other liabilities. Thus, the risk of a
shareholder incurring financial loss on account of shareholder liability is
limited to circumstances in which both inadequate insurance exists and the Trust
itself is unable to meet its obligations.

Each share of each series of the Trust represents an equal proportionate
interest in that series and is entitled to such dividends and distributions out
of the income belonging to such shares as declared by the Board. Upon any
liquidation of the Trust, shareholders are entitled to share pro rata in the net
assets belonging to that series available for distribution.

The Prospectus and this Statement of Additional Information do not contain all
the information in the Funds' registration statement. The registration statement
is on file with the Securities and Exchange Commission and is available to the
public.

CORPORATE BOND AND COMMERCIAL PAPER RATINGS

The following is a description of Moody's Investors Service, Inc.'s bond
ratings:

Aaa: Bonds which are rated Aaa are judged to be of the best quality. They carry
the smallest degree of investment risk and are generally referred to as "gilt
edged." Interest payments are protected by a large or by an exceptionally stable
margin and principal is secure. While the various protective elements are likely
to change, such changes as can be visualized are unlikely to impair the
fundamentally strong position of such issues.

Aa: Bonds which are rated Aa are judged to be of high quality by all standards.
Together with the Aaa group, they compromise what are generally known as high
grade bonds. They are rated lower than the best bonds because margins of
protection may not be as large as in Aaa securities or fluctuation of protective
elements may be of greater amplitude or there may be other elements present
which make long-term risks appear somewhat larger than Aaa securities.

A: Bonds which are rated A possess many favorable investment attributes and are
to be considered as upper-medium-grade obligations. Factors giving security to
principal and interest are considered adequate, but elements may be present
which suggest a susceptibility to impairment sometime in the future.

Baa: Bonds which are rated Baa are considered as medium grade obligations, i.e.
they are neither highly protected nor poorly secured. Interest payments and
principal security appear adequate for the present but certain protective
elements may be lacking or may be characteristically unreliable over any great
length of time. Such bonds lack outstanding investment characteristics and in
fact have speculative characteristics as well.

The following is a description of Standard & Poor's Corporation's investment
grade bond ratings:

AAA: Bonds rated AAA are considered highest grade obligations. They possess the
ultimate degree of protection as to principal and interest. They move with
market interest rates, and thus provide the maximum safety on all counts.

AA: Bonds rated AA are high-grade obligations. In the majority of instances,
they differ from AAA issues only to a small degree. Prices of AA bonds also move
with the long-term money market.

A: Bonds rated A are upper medium grade obligations. They have considerable
investment strength, but are not entirely free from adverse effects of change in
economic and trade conditions. Interest and principal are regarded as safe. They
predominantly reflect money rates in their market behavior but, to some extent,
also economic conditions.

BBB: Bonds rated BBB are medium grade obligations. They are considered
borderline between definitely sound obligations and those where the speculative
element begins to predominate. These bonds have adequate asset coverage and are
normally protected by satisfactory earnings. Their susceptibility to changing
conditions, particularly to depressions, necessitates constant monitoring. These
bonds are more responsive to business and trade conditions than to interest
rates. This group is the lowest that qualifies for commercial bank investment.

Commercial paper rated A by Standard & Poor's Corporation has the following
characteristics: liquidity ratios are adequate to meet cash requirements; long-
term senior debt is rated "A" or better; the issuer has access to at least two
adequate channels of borrowing; basic earnings and cash flow have an upward
trend with allowance made for unusual circumstances; typically, the issuer's
industry is well-established and the issuer has a strong position within the
industry; and the reliability and quality of management are unquestioned. The
relative strength or weakness of the above factors determines whether an
issuer's commercial paper is rated A-1, A-2, or A-3.

Issuers rated Prime-1 by Moody's Investors Services, Inc., are considered to
have superior capacity of repayment of short-term promissory obligations. Such
repayment capacity will normally be evidenced by the following characteristics:
leading market positions in well-established industries; high rates of return on
funds employed; conservative capitalization structure with moderate reliance on
debt and ample asset protection; broad margins in earnings coverage of fixed
financial charges and high internal cash generation; and well-established access
to a range of financial markets and assured sources of alternate liquidity.
Issuers rated Prime-2 have a strong capacity for repayment of short-term
promissory obligations. This will normally be evidenced by many of the
characteristics cited above but to a lesser degree. Earnings trends and coverage
ratios, while sound, will be more subject to variation. Capitalization
characteristics, while still appropriate, may be more affected by external
conditions. Ample alternate liquidity is maintained.

                              DECLARATION OF TRUST


     DECLARATION OF TRUST made this _______ day of ________________, 19___, by 
John G. Guffey, Jr., and Wayne B. Bardsley, as Trustees.

     WHEREAS, the Trustees desire to establish a trust fund for the investment 
and reinvestment of funds contributed thereto;

     NOW, THEREFORE, the Trustees declare that all money and property 
contributed to the trust fund hereunder shall be held and managed under this
Declaration of Trust IN TRUST as herein set forth below.

                                   ARTICLE I
                             NAMES AND DEFINITIONS

     Section 1.  Name.  This Trust shall be known as Ariel Growth Fund.  Should
the Trustees determine that the use of such name is not advisable or otherwise 
cease using such name, then they may hold the property of the Trust and conduct
its business under another name of their choosing, and shall undertake to change
the name of the Trust accordingly.

     Section 2.  Definitions.  Wherever used herein, unless otherwise required 
by the context or specifically provided:

          (a)  The terms "Affiliated Person," "Assignment," "Interested Person,"
     "Majority Shareholder Vote" (the 67% or 50% requirement of the third
     sentence of Section 2(a) (42) of the 1940 act, whichever may be
     applicable), and "Principal Underwriter" shall have the meanings given them
     in the Investment Company Act of 1940, as amended from time to time;

          (b)  The "Trust" refers to Ariel Growth Fund.

          (c)  "Accumulated Net Income" means the accumulated net income of the
     Trust determined in the manner provided or authorized in Article X, Section
     3;

          (d)  "Shareholder" means a record owner of Shares of the Trust;

          (e)  The "Trustees" refers to the individual trustees in their 
     capacity as trustees hereunder of the Trust and their successor or
     successors for the time being in office as such Trustees;
<PAGE>
 
          (f)  "Shares" means the equal proportionate units of interest into
     which the beneficial interest in the Trust shall be divided from time to
     time and includes fractions of shares as well as whole shares;

          (g)  The "1940 Act" refers to the Investment Company Act of 1940, as 
     amended from time to time;

          (h)  The "Commission" refers to the Commission described in the 1940
     Act and to any succeeding governmental authority; and

          (i)  A "Business Day" day means a day when the New York Stock Exchange
     is open for trading and the Trustees have not determined that the Trust
     shall be closed for business in observance of a holiday observed generally
     by banks in New York City, Washington, D.C., or by the offices of the
     Federal Government in Washington, D.C.

                                   ARTICLE II
                                PURPOSE OF TRUST

     The Trust is organized to operate as an investment company registered under
the 1940 Act for the purpose of investing and reinvesting its assets in
securities.

                                  ARTICLE III
                              BENEFICIAL INTEREST

     Section 1.  Shares of Beneficial Interest.  The beneficial interest in the 
Trust shall at all times be divided into transferable Shares, without par value,
each of which shall represent an equal proportionate interest in the Trust with
each other Share outstanding, none having priority or preference over another,
except to the extent modified by the Trustees under the provisions of this
section. The number of Shares which may be issued is unlimited. The Trustees may
from time to time divide or combine the outstanding Shares into a greater or
lesser number without thereby changing the proportionate beneficial interest in
the Trust. Contributions to the Trust may be accepted for, and Shares shall be
redeemed as, whole shares and/or fractions. Shares may be represented by
certificates or by suitable entries in the books of the Trust.

     From time to time as they deem appropriate, the Trustees may create Series
and/or Classes of Shares. References in this Declaration of Trust to Shares of
the Trust shall apply to each such Series of Shares and (to the extent not
inconsistent with the rights and restrictions of a Class) to each such Class of
Shares, except to the extent modified by the Trustees under the provisions of
this Section.

     Any Series of Shares created hereunder shall represent the beneficial
interest in the assets (and related liabilities) allocated by the Trustees to
such Series of Shares and acquired by the Trust only after creation of the
respective Series of Shares and only on the account of such Series. Upon
creation of any Series of Shares, the Trustees shall designate it appropriately
and determine

                                       2
<PAGE>
 
the investment policies with respect to the assets allocated to such Series of
Shares, preferences, redemption rights, dividend rights, conversion rights,
liquidation rights, voting rights, and such other rights and restrictions as the
Trustees deem appropriate, to the extent not inconsistent with the provisions of
this Declaration of Trust.

     The Trustees may divide the Shares or any Series of Shares into more than
one Class. Upon creation of any additional Class of Shares, the Trustees shall
designate it appropriately and determine its preferences, redemption rights,
dividend rights, conversion rights, liquidation rights, voting rights, and such
other rights and restrictions as the Trustees deem appropriate.

     Section 2.  Ownership of Shares.  The ownership of Shares shall be
recorded in the books of the Trust or of a transfer agent.  The Trustees may
make such rules as they consider appropriate for the transfer of shares and
similar matters.  The record books of the Trust or any transfer agent, as the
case may be, shall be conclusive as to who are the holders of the Shares and as
to the number of Shares held from time to time by each.

     Section 3.  Investment in the Trust.  The Trustees may accept investments 
in the Trust from such persons and on such terms as they may from time to time
authorize and may cease offering Shares to the public at any time. After the
date of the initial contribution of capital to the Trust, the number of Shares
determined by the Trustees to represent the initial contribution shall be
considered as outstanding, and the amount received by the Trustees on account of
the contribution shall be treated as an asset of the Trust. Subsequent to such
initial contribution of capital, Shares (including Shares which may have been
redeemed or repurchased by the Trust) may be issued or sold at a price which
will net the Trust, before paying any taxes in connection with such issue or
sale, not less than the net asset value (as defined in Article X, Section 4)
hereof; provided, however, that the Trustees may in their discretion impose a
sales charge upon investments in the Trust.

     Section 4.  No Pre-emptive Rights.  Shareholders shall have no pre-emptive 
or other right to subscribe to any additional Shares or other securities issued
by the Trust or the Trustees.

     Section 5.  Provisions Relating to Series of Shares.  Whenever no Shares of
a Series are outstanding, then the Trustees may abolish such Series (or any
Class of Shares of a Series for which there are no outstanding Shares). Whenever
more than one Series of Shares is outstanding, then the following provisions
shall apply:

     (a)  Assets Belonging to Each Series.  All consideration received by the 
Trust for the issue or sale of Shares of a particular Series, together with all
assets in which such consideration is invested or reinvested, all income,
earnings, and proceeds thereof, and any funds derived from any reinvestment of
such proceeds, shall irrevocably belong to that Series for all purposes, subject
only to the rights of creditors, and shall be so recorded upon the books of the
Trust. In the event there are assets, income, earnings, and proceeds thereof
which are not readily identifiable as belonging to a particular Series, then the
Trustees shall allocate such items to the various Series then existing, in such
manner and on such basis as they, in their sole discretion, deem fair and

                                       3
<PAGE>
 
equitable.  The amount of each such item allocated to a particular Series by the
Trustees shall then belong to that Series, and each such allocation shall be
conclusive and binding upon Shareholders of all Series for all purposes.

     (b)  Liabilities Belonging to Each Series.  The assets belonging to each 
particular Series shall be charged with the liabilities, expenses, costs and
reserves of the Trust attributable to that Series; any general liabilities,
expenses, costs and reserves of the Trust which are not readily identifiable as
attributable to a particular Series shall be allocated by the Trustees to the
various Series then existing, in such manner and on such basis as they, in their
sole discretion, deem fair and equitable. Each such allocation shall be
conclusive and binding upon the Shareholders of all Series for all purposes.

     (c)  Series Shares, Dividends and Liquidation.  Each Share of each
respective Class of a Series shall have the same rights and pro rata beneficial
interest in the assets and liabilities of the Series as any other such Share.
Any dividends paid on the Shares of any Series shall be only payable from and to
the extent of the assets (net of liabilities) belonging to that Series.  In the
event of liquidation of a Series, only the assets (less provision for
liabilities) of that Series shall be distributed to the holders of the Shares of
that Series.

     (d)  Voting by Series.  Except as provided in this section or as limited by
the rights and restrictions of any Class, each Share of the Trust shall vote
with and in the same manner as any other Share on matters submitted to a vote of
the Shareholders, without differentiation among votes from the separate Series;
provided, however, that (i) as to any matter with respect to which a separate
vote of any Series is required by the 1940 Act or would be required under the
Massachusetts Business Corporation Law if the Trust were a Massachusetts
Business Corporation, such requirements as to a separate vote by the Series
shall apply in lieu of the voting described above herein; (ii) in the event that
the separate vote requirements referred to in (i) above apply with respect to
one or more Series, then, subject to (iii) below, the Shares of all other Series
shall vote without differentiation among their votes; and (iii) as to any matter
which does not affect the interest of a particular Series, only the holders of
Shares of one or more affected Series shall be entitled to vote.

                                   ARTICLE IV
                                  THE TRUSTEES

     Section 1.  Management of the Trust.  The business and affairs of the Trust
shall be managed by the Trustees, and they shall have all powers necessary and 
desirable to carry out that responsibility.

     Section 2.  Election of Trustees.  The individuals executing as Trustees 
this Declaration of Trust shall serve until their successors are elected at the
first meeting of the sole shareholder of the Trust and such successors accept
their appointments. Thereafter, the Trustees shall serve for such regular terms
as may be provided in the By-laws of the Trust.

                                       4
<PAGE>
 
     Section 3.  Term of Office of Trustees.  The Trustees shall hold office 
during the lifetime of this Trust and until the expiration of the term of office
for which each was elected, except that (a) any Trustee may resign this trust by
written instrument signed by him and delivered to the other Trustees, which
shall take effect upon such delivery or upon such later date as is specified
therein; (b) any Trustee may be removed at any time by written instrument signed
by at least two-thirds of the number of Trustees prior to such removal,
specifying the date when such removal shall become effective; (c) any Trustee
who requests in writing to be retired or who has become mentally or physically
incapacitated may be retired by written instrument signed by a majority of the
other Trustees, specifying the date of his retirement; (d) a Trustee may be
removed at any special meeting of Shareholders of the Trust by a vote of two-
thirds of the outstanding Shares; and (e) a Trustee may be removed upon the
filing with the Custodian appointed pursuant to Article IX hereof a written
declaration signed by shareholders holding in the aggregate two-thirds of the
outstanding stocks.

     Section 4.  Termination of Service and Appointment of Trustees.  In case of
the death, resignation, retirement, removal or mental or physical incapacity of
any of the Trustees, or in case a vacancy shall, by reason of an increase in
number, or for any other reason, exist, the remaining Trustees shall fill such
vacancy by appointing for the remaining term of the predecessor Trustee such
other person as they in their discretion shall see fit. Such appointment shall
be effected by the signing of a written instrument by a majority of the Trustees
in office. Within three months of such appointment, the Trustees shall cause
notice of such appointment to be mailed to each Shareholder at his address as
recorded on the books of the Trust. An appointment of a Trustee may be made by
the Trustees then in office and notice thereof mailed to Shareholders as
aforesaid in anticipation of a vacancy to occur by reason of retirement,
resignation or increase in number of Trustees effective at a later date,
provided that said appointment shall become effective only at or after the
effective date of said retirement, resignation or increase in number of
Trustees. As soon as any Trustee so appointed shall have accepted this Trust,
the trust estate shall vest in the new Trustee or Trustees, together with the
continuing Trustees, without any further act or conveyance, and he shall be
deemed a Trustee hereunder. Any appointment authorized by this Section 4 is
subject to the provisions of Section 16(a) of the 1940 Act, as applicable.

     Section 5.  Temporary Absence of Trustee.  Any Trustee may, by power of 
attorney, delegate his power for a period not exceeding six months at any one
time to any other Trustee or Trustees, provided that in no case shall less than
two of the Trustees personally exercise their power hereunder, except as herein
otherwise expressly provided.

     Section 6.  Number of Trustees.  The number of Trustees serving hereunder 
at any time shall be determined by the Trustees themselves, but once Shares have
been issued shall not be less than three (3) nor more than fifteen (15).

     Whenever a vacancy in the Board of Trustees shall occur, until such
vacancy is filled or while any Trustee is physically or mentally incapacitated,
the other Trustees shall have all the powers hereunder and the certificate
signed by a majority of the other Trustees of such vacancy, absence or
incapacity, shall be conclusive, provided, however, that no vacancy which
reduced the

                                       5
<PAGE>
 
number of Trustees below three (3) shall remain unfilled for a period longer
than six calendar months.

     Section 7.  Effect of Death, Resignation, etc., of a Trustee.  The death, 
resignation, retirement, removal or mental or physical incapacity of the
Trustees, or any one of them, shall not operate to annul the Trust or to revoke
any existing agency created pursuant to the terms of this Declaration of Trust.

     Section 8.  Ownership of the Trust.  The assets of the Trust shall be held 
separate and apart from any assets now or hereafter held in any capacity other
than as Trustee hereunder by the Trustees or by any successor Trustees. All of
the assets of the Trust shall at all times be considered as vested in the
Trustees. No Shareholder shall be deemed to have severable ownership in any
individual asset of the Trust or any right of partition or possession thereof,
but each Shareholder shall have a proportionate undivided beneficial interest in
the Trusts.

                                   ARTICLE V
                             POWER OF THE TRUSTEES

     Section 1.  Powers.  The Trustees in all instances shall act as principals 
and are and shall be free from the control of the Shareholders. The Trustees
shall have full power and authority to do any and all acts and to make and
execute any and all contracts and instruments that they may consider necessary
or appropriate in connection with the management of the Trust. The Trustees
shall not be bound or limited by present or future laws or customs in regard to
investment by Trustees or fiduciaries, but shall have full authority and power
to make any and all investments which they, in their uncontrolled discretion,
shall deem proper to accomplish the purpose of this Trust. Without limiting the
foregoing, the Trustees shall have the following specific powers and authority,
subject to any applicable limitation in this Declaration of Trust or in the By-
Laws of the Trust.

     (a)  To buy, and invest funds of the Trust, in securities including, but 
not limited to, common stocks, preferred stocks, bonds, debentures, warrants and
rights to purchase securities, options, certificates of beneficial interest,
money market instruments, notes or other evidences of indebtedness issued by
corporations, trusts, associations, or banking institutions, domestic or
foreign, or issued or guaranteed by the United States of America or any agency
or instrumentality thereof, by the government of any foreign country, by any
State of the United States (including the District of Columbia, Puerto Rico and
Guam) or by any political subdivision or agency or instrumentality of any State
or foreign country, or in "when-issued" or "delayed-delivery" contracts for any
such securities, or in any repurchase agreement (agreement under which the
seller agrees at the time of sale to repurchase the security at an agreed time
and price); or retain Trust assets in cash, and from time to time change the
investments constituting the assets of the Trust;

                                       6
<PAGE>

     Section 2.  Trustees and Officers as Shareholders.  Any Trustee, officer or

                  INVESTMENT ADVISER, ADMINISTRATIVE SERVICES,

may from time-to-time adopt) to effect purchases, sales or exchanges of
portfolio securities of the Trust of behalf of the Trustees or may authorize any

adviser to determine what firms shall be employed to effect transactions in
securities for the account of the Trust and to determine what firms shall
participate in any such transactions or shall share in commissions or fees
charged in connection with such transactions.

one or more entities.

     Section 3.  Principal Underwriter.  The Trustees may in their discretion 
from time-to-time enter into an exclusive or non-exclusive contract or contracts
providing for the sale of the shares of the Trust to net the Trust not less than
the amount provided in Article III, Section 3 hereof, whereby the Trust may
either agree to sell the Shares to the other party to the contract or appoint
such other party its sales agent for such shares. In either case, the contract
shall be on such terms and conditions as the Trustees may in their discretion
determine not inconsistent with the provisions of this Article VII; and such
contracts may also provide for the repurchase or sales of Shares of the Trust by
such other party as principal or as agent of the Trust and may provide that the
other party may maintain a market for shares of the Trust.

                                  ARTICLE VIII
                    SHAREHOLDERS' VOTING POWERS AND MEETINGS

     Section 1.  Voting Powers.  The Shareholders shall have power to vote (i) 
for the election of Trustees as provided in Article IV, Section 2; (ii) for
the removal of Trustees as provided in Article IV, Section 3(d); (iii) with
respect to any investment adviser or sub-investment adviser as provided in
Article VII, Section 1; (iv) with respect to the amendment of this Declaration
of Trust as provided in Article XII, Section 7; (v) to the same extent as the
Shareholders of a Massachusetts business corporation as to whether or not a
court action, proceeding or claim should be brought or maintained derivatively
or a class action on behalf of the Trust or the Shareholders; and (vi) with
respect to such additional matters relating to the Trust as may be required by
law, by this Declaration of Trust, or by By-Laws of the Trust or any regulation
of the Trust by the Commission or any State, or as the Trustees may consider
desirable.  Each whole Share shall be entitled to one vote as to any matter on
which it is entitled to vote, and each fractional Share shall be entitled to a
proportionate fractional vote.  There shall be no cumulative voting in the
election of Trustees.  Until Shares are issued, the Trustees may exercise all
rights of Shareholders and may take any action required or permitted by law,
this Declaration of Trust or any By-Laws of the Trust to be taken by
Shareholders.

     Section 2.  Meetings.  Shareholder meetings shall be held as specified in 
Section 2 of Article IV and in the By-Laws at the principal office of the Trust 
or at such other place as the

                                       11
<PAGE>
 
Trustees may designate.  Special meetings of the Shareholders may be called by
the Trustees or by officers of the Trust given such authority in the By-Laws and
shall be called by the Trustees at a place designated by them upon the written
request of Shareholders owning at least one-tenth of the outstanding Shares
entitled to vote.  Shareholders shall be entitled to at least ten days' notice
of any meeting.

     Section 3.  Quorum and Required Vote.  Except as otherwise provided by law,
to constitute a quorum for the transaction of any business at any meeting of 
Shareholders there must be present, in person or by proxy, holders of one-fourth
of the total number of Shares of the Trust then outstanding and entitled to vote
at such meeting. If a quorum, as above defined, shall not be present for the
purpose of any vote that may properly come before the meeting, the Shareholders
present in person or by proxy and entitled to vote at such meeting on such
matter holding a majority of the Shares present entitled to vote on such matter
may by vote adjourn the meeting from time-to-time to be held at the same place
without further notice than by announcement to be given at the meeting until a
quorum, as above defined, entitled to vote on such matter shall be present,
whereupon any such matter may be noted upon at the meeting as though held when
originally convened. Subject to any applicable requirement of law or of this
Declaration of Trust or by the By-Laws, a plurality of the votes cast shall
elect a Trustee and all other matters shall be decided by a majority of the
votes cast entitled to vote thereon.

     Section 4.  Proxies.  Any vote by a Shareholder of the Trust may be made in
person or by proxy, provided that no proxy shall be noted at any meeting unless
it shall have been placed on file with the Trustees or their designate prior to
the time the vote is taken. Pursuant to a resolution of a majority of the
Trustees, proxies may be solicited in the name of one or more Trustees or one or
more officers of the Trust. Only Shareholders of record shall be entitled to
vote. A proxy purporting to be executed by or on behalf of a Shareholder shall
be deemed valid unless challenged at or prior to its exercise, and the burden of
providing invalidity shall rest on the challenger.

     Section 5.  Additional Provisions.  The By-Laws may include further 
provisions for Shareholders' votes and meetings and related matters.

                                   ARTICLE IX
                                   CUSTODIANS

     Section 1.  Appointment of Custodian and Duties.  The Trustees shall
appoint or otherwise engage a bank or trust company having an aggregate capital,
surplus and undivided profits (as shown in its last published report) of at
least two million dollars ($2,000,000) as its Custodian with authority as its
agent, but subject to such restrictions, limitations and other requirements, if
any, as may be contained in the By-Laws of the Trust:

     (a)  To receive and hold securities owned by the Trust and deliver the same
upon written order;

                                       12
<PAGE>
 
     (b)  To receive and receipt for any moneys due to the Trust and deposit the
same in its own banking department or elsewhere as the Trustees may direct;

     (c)  To disburse such funds upon orders or vouchers;

     (d)  To keep, if authorized to do so by the Trustees, the books and 
accounts of the Trust and furnish clerical and accounting services; and

     (e) To compute, if authorized to do so by the Trustees, the Accumulated Net
Income of the Trust and the net asset value of the Shares in accordance with the
provisions hereof;

all upon such basis of compensation as may be agreed upon between the Trustees
and the Custodian.  If so directed by a Majority Shareholder Vote, the Custodian
shall deliver and pay over all property of the Trust held by it as specified in
such vote.

     The Trustee may also authorize the Custodian to employ one or more
sub-custodians from time-to-time to perform such of the acts and services of the
Custodian and upon such terms and conditions, as may be agreed upon between the
Custodian and such sub-custodian and approved by the Trustees, provided that in
every case such sub-custodian shall be a bank or trust company organized under
the laws of the United States or one of the States thereof and having an
aggregate capital, surplus and undivided profits (as shown in its last published
report) of at least two million dollars ($2,000,000) or a member firm of a
national securities exchange registered under the Securities Exchange Act of
1934.

     Section 2.  Central Certificate System.  Subject to such rules, 
regulations and orders as the Commission may adopt, the Trustees may direct the
Custodian to deposit all or any part of the securities owned by the Trust in a
system for the central handling of securities established by a national
securities exchange or a national securities association registered with the
Commission under the Securities Exchange Act of 1934, or such other person as
may be permitted by the Commission or otherwise in accordance with the 1940 Act,
pursuant to which system all securities of any particular class or series of any
issuer deposited within the system are treated as fungible and may be
transferred or pledged by bookkeeping entry without physical delivery of such
securities, provided that all such deposits shall be subject to withdrawal only
upon the order of the Custodian at the direction of the Trustees.

     Section 3.  Special Custodians.  The Trustees may appoint or otherwise
engage any institution which would be permitted to act as a sub-custodian
hereunder to act as a Special Custodian of the Trust.  Any Special Custodian
which is a member firm of a national securities exchange shall have custody only
of securities owned by the Trust and shall not hold any of its cash.  Special
Custodians shall be appointed pursuant to a written agreement approved and
thereafter at least annually ratified by the Trustees, and any such written
agreement shall meet such requirements as may be specified by law or by the
regulations of the Commission.  Any such written agreement with a member firm of
a national securities exchange shall also require that the Special Custodian
shall deliver to the Custodian its receipt, evidencing that it holds the
specific

                                       13
<PAGE>
 
securities in question of behalf of the Trust in its safekeeping, before any
payment can be made for such securities by the Trust.  Special Custodians shall
be used by the Trust only for proposes of safekeeping designated types of
securities for periods of limited duration in cases where, in the opinion of the
Trustees, officers of the Trust, its investment adviser or other authorized
agent, such safekeeping services would be more appropriate or convenient to the
Trust than the safekeeping of such securities with the Custodian.

     Section 4.  Special Depositories.  The Trustees may by resolution
appoint as Special Depositories any commercial banks insured by the Federal
Deposit Insurance Corporation having aggregate capital, surplus and undivided
profits (as shown in their respective last published reports) of at least two
million dollars ($2,000,000).  The Trust may maintain with a Special Depository
only demand deposit accounts and shall not permit the aggregate balances in such
accounts to exceed the amount of any fidelity bond covering any officer of the
Trust authorized by the Trustees to have signature authority over such demand
deposit accounts.

                                   ARTICLE X
                         DISTRIBUTIONS AND REDEMPTIONS

     Section 1.  Distributions.

     (a)  The Trustees may from time-to-time declare and pay dividends, and the 
amount of such dividends and the payment of them shall be wholly in the
direction of the Trustees.

     (b)  The Trustees may declare Accumulated Net Income of the Trust (as
defined in Section 3 of this Article X) as a dividend to Shareholders of record
at such time as the Trustees shall designate, payable in additional full and
fractional Shares or in cash.  The Trustees may, if they deem it advisable,
declare a negative dividend (or reverse split) and deduct such amount from the
previously accumulated dividends of each Shareholder or from such Shareholder's
interest in the Trust.

     (c)  The Trustees may distribute in respect of any fiscal year as ordinary 
dividends and as capital gains distributions, respectively, amounts sufficient
to enable the Trust as a regulated investment company to avoid any liability for
federal income taxes in respect of that year.

     (d)  The decision of the Trustees as to what, in accordance with good
accounting practice, is income and what is principal shall be final, and except
as specifically provided herein, the decision of the Trustees as to what
expenses and charges of the Trust shall be charged against principal and what
against income shall be final.  Any income not distributed in any year may be
permitted to accumulate and as long as not distributed may be invested from
time-to-time in the same manner as the principal funds of the Trust.

     (e)  The Trustees shall have power, to the fullest extent permitted by law,
at any time or from time-to-time, to declare and cause to be paid dividends, 
which, at the election of the

                                       14
<PAGE>
 
Trustees, may be accrued, automatically reinvested in additional Shares (or
fractions thereof) of the Trust or paid in cash or additional Shares, all upon
such terms and conditions as the Trustees may prescribe.

     (f)  Anything in this instrument to the contrary notwithstanding, the
Trustees may at any time declare and distribute a dividend consisting of Shares
of the Trust.

     Section 2.  Redemptions and Repurchases.

     (a)  If any Shareholder of record of the Trust at any time desires or
authorizes the disposition of Shares recorded in his name, he or his authorized
agent may deposit a written request (or such other form of request as the
Trustees may from time-to-time authorize) requesting that the Trust purchase his
Shares, together with such other instruments or authorization to effect the
transfer as the Trustees may from time-to-time require, at the office of the
Trust, and the Trust shall purchase his said Shares, but only at the net asset
value of such Shares (as defined in Section 4 of this Article X) next determined
by or on behalf of the Trustees after said request.

     Payment for such Shares shall be made by the Trust to the Shareholder of 
record at a time determined by the Trustees within seven (7) days after the
date upon which the request (and, if required, such other instruments or
authorizations of transfer is deposited, subject to the right of the Trustees to
postpone the date of payment pursuant to Section 5 of this Article X.  If the
redemption is postponed beyond the date on which it would normally occur by
reason of a declaration by the Trustees suspending the right of redemption
pursuant to Section 5 of this Article X, the right of the Shareholder to have
his shares purchased by the Trust shall be similarly suspended, and he may
withdraw his request (or such other instruments or authorizations of transfer)
from deposit if he so elects; or, if he does not so elect, the purchase price
shall be the net asset value of his Shares, determined next after termination of
such suspension and payment therefor shall be made within seven (7) days
thereafter.

     (b)  The Trust may purchase Shares of the Trust by agreement with the
owner thereof (1) at the price not exceeding the net asset value per share
determined next after the purchase or contract of purchase is made or (2) at a
price not exceeding the net asset value per Share determined at some later time.

     (c)  Shares purchased by the Trust either pursuant to paragraph (a) or
paragraph (b) of this Section 2 shall be deemed treasury Shares and may be
resold by the Trust.

     (d)  If the Trustees determine that economic conditions would make it
seriously detrimental to the best interests of the remaining Shareholders of the
Trust to make payment wholly or partly in cash, the Trust may pay the redemption
price in whole or in part by a distribution in kind of securities from the
portfolio of the Trust, in lieu of cash, in conformity with applicable rules of
the Commission, taking such securities at the same value employed in

                                       15
<PAGE>
 
determining net asset value and selecting the securities in such manner as the
Trustees may deem fair and equitable.

     Section 3.  Determination of Accumulated Net Income.  The Accumulated Net 
Income of the Trust shall be determined by or on behalf of the Trustees daily or
more frequently at the discretion of the Trustees, on each business day at such
time or times as the Trustees shall in their discretion determine. Such
determination shall be made in accordance with generally accepted accounting
principles and practices and the accounting policies established by the Trustees
and may include realized and/or unrealized gains from the sale or disposition of
securities or other property of the Trust. The power and duty to determine
Accumulated Net Income may be delegated by the Trustees from time-to-time to one
or more of the Trustees or officers of the Trust, to the other party to any
contract entered into pursuant to Section 1 or 2 of Article VII, or to the
Custodian or to a transfer agent.

     Section 4.  Net Asset Value of Shares.  The net asset value of each share 
of the Trust outstanding shall be determined at least once on each business day
by or on behalf of the Trustees. The power and duty to determine net asset value
may be delegated by the Trustees from time-to-time to one or more of the
Trustees or officers of the Trust, to the other party to any contract entered
into pursuant to Section 1 or 2 of Article VII, or to the Custodian or to a
transfer agent.

     The net asset value of each Share of the Trust as of any particular time
shall be the quotient (adjusted to the number of significant digits determined
by the Trustees) obtained by dividing the value, as of such time, of the net
assets of the Trust (i.e., the value of the assets of the Trust less its
liabilities exclusive of capital and surplus) by the total number of Shares
outstanding (exclusive of treasury Shares) at such time in accordance with the
requirements of the 1940 Act and any applicable rules, regulations and orders
thereunder, and applicable provisions of the By-Laws of the Trust in conformity
with generally accepted accounting practices and principles.

     Section 5.  Suspension of the Rights of Redemption.  The Trustees may
declare a suspension of the determination of net asset value and/or the right of
redemption or postpone the date of payment for the whole or any part of any
period (i) during which the New York Stock Exchange is closed other than
customary weekend and holiday closings, (ii) during which trading on the New
York Stock Exchange is restricted, (iii) during which an emergency exists as a
result of which disposal by the Trust of securities owned by it is not
reasonably practicable or it is not reasonable practicable for the Trust fairly
to determine the value of its net assets, or (iv) during any other period when
the Commission may permit suspension of the right of redemption or postponement
of the date of payment on redemption by order, rule or interpretation for the
protection of security holdings of the Trust; provided that applicable rules,
interpretations and regulations of the Commission shall govern as to whether the
conditions prescribed in (ii) or (iii) exist.  Such suspension shall take effect
at such time as the Trustees shall specify but not later than the close of
business on the business day next following the declaration of suspension, and
thereafter there shall be no right of redemption or payment until the Trustees
shall declare the suspension at an end, except that the suspension shall
terminate in any event on the first day on which said Stock Exchange shall have
reopened or the period specified in (ii) or (iii) shall have

                                       16
<PAGE>
 
expired (as to which in the absence of an official ruling by the Commission, the
determination of the Trustees shall be conclusive).

     Section 6.  Trust's Right to Redeem Shares.  The Trust shall have the
right to cause the redemption of Shares in any Shareholder's account for their
then current net asset value (which will be promptly paid to the Shareholder in
cash) if at any time the total investment in the account does not have a minimum
dollar value determined from time-to-time by the Trustees in their sole
discretion. Shares of the Trust are redeemable at the option of the Trust if, in
the opinion of the Trustees, ownership of the Trust Shares has or may become
concentrated to an extent which would cause the Trust to be a personal holding
company within the meaning of the Internal Revenue Code of 1954, as amended, and
any successor statute (and thereby disqualified under Sub-chapter M of said
Code); in such circumstances the Trust may compel the redemption of Shares,
reject any order for the purchase of Shares or refuse to give effect to the
Transfer of Shares.

                                   ARTICLE XI
                  LIMITATION OF LIABILITY AND INDEMNIFICATION

     Section 1.  Limitation of Personal Liability and Indemnification of
Shareholders.  The Trustees, officers, employees or agents of the Trust shall
have no power to bind any Shareholder personally or to call upon any Shareholder
for the payment of any sum of money or assessment whatsoever, other than such as
the Shareholder may at any time agree to pay by way of subscription to any
Shares or otherwise.

     No Shareholder or former Shareholder of the Trust shall be liable solely by
reason of his being or having been a Shareholder for any debt, claim, action,
demand, suit, proceeding, judgment, degree, liability or obligation of any kind,
against, or with respect to the Trust arising out of any action taken or omitted
for or on behalf of the Trust, and the Trust shall be solely liable therefor and
resort shall be had solely to the Trust property for the payment or performance
thereof.

     Each Shareholder or former Shareholder of the Trust (or their heirs,
executors, administrators or other legal representatives of, in case of a
corporate entity, its corporate or general successor) shall be entitled to
indemnity and reimbursement out of the Trust property to the full extent of such
liability and the costs of any litigation or other proceedings in which such
liability shall have been determined, including, without limitation, the fees
and disbursements of counsel if, contrary to the provisions hereof, such
Shareholder or former Shareholder of the Trust shall be held to personal
liability.

     The Trust shall, upon request by the Shareholder or former Shareholder,
assume the defense of any claim made against any shareholder for any act or
obligation of the Trust and satisfy any judgment thereon.

                                       17
<PAGE>
 
     Section 2.  Limitation of Personal Liability of Trustees, Officers,
Employees or Agents of the Trust.  No Trustee, officer, employee or agent of the
Trust shall have the power to bind any other Trustee, officer, employee or agent
of the Trust personally.  The Trustees, officers, employees or agents of the
Trust incurring any debts, liabilities or obligations, or in taking or omitting
any other actions for or in connection with the Trust are, and each shall be
deemed to be, acting as Trustee, officer, employee or agent of the Trust and not
in his own individual capacity.

     Provided they have acted under the belief that their actions are in the
best interest of the Trust, the Trustees and officers shall not be responsible
for or liable in any event for neglect or wrongdoing by them or any officer,
agent, employee, investment adviser, principal underwriter, transfer agent or
custodian of the Trust or of any entity providing administrative services for
the Trust, but nothing herein contained shall protect any Trustee or officer
against any liability to which he would otherwise be subject by reason of
willful misfeasance, bad faith, gross negligence or reckless disregard of the
duties involved in the conduct of his office.

     Section 3.  Express Exculpatory Clauses and Instruments.  The Trustees 
shall use appropriate means to assure that all persons having dealings with the
Trust shall be informed that the property of the Shareholders and the Trustees,
officers, employees and agents of the Trust shall not be subject to claims
against or obligations of the Trust to any extent whatsoever.  The Trustees may
cause to be inserted in any written agreement, undertaking or obligation made or
issued on behalf of the Trust (including certificates for Shares of the Trust)
an appropriate reference to this Declaration, providing that neither the
Shareholders, the Trustees, the officers, the employees nor any agent of the
Trust shall be liable thereunder, and that the other parties to such instrument
shall look solely to the Trust property for the payment of any claim thereunder
or for the performance thereof; but the omission of such provisions from any
such instrument shall not render any Shareholder, Trustee, officer, employee or
agent liable, nor shall the Trustee, or any officer, agent or employee of the
Trust be liable to anyone for such omission.  If, notwithstanding this
provision, any Shareholder, Trustee, officer, employee or agent shall be held
liable to any other person by reason of the omission of such provision from any
such agreement, undertaking or obligation, the Shareholder, Trustee, officer,
employee or agent shall be entitled to indemnity and reimbursement out of the
Trust property, as provided in this Article XI.

     Section 4.  Mandatory Indemnification.

     (a)  Subject only to the provisions hereof and any applicable provisions of
the By-Laws of the Trust, every person who is or has been a Trustee, officer,
employee or agent of the Trust and every person who serves at the Trust's
request as director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprises shall be indemnified by
the Trust to the fullest extent permitted by law against all liabilities and
against all expenses reasonably incurred or paid by him in connection with any
debt, claim, action, demand, suit, proceeding, judgment, decree, liability or
obligation of any kind in which he becomes involved as a party or otherwise or
is threatened by virtue of his being or having been a Trustee, officer, employee
or agent of the Trust or of another corporation, partnership, joint venture,
trust or other

                                       18
<PAGE>
 
enterprise at the request of the Trust against amounts paid or incurred by him
in the compromise or settlement thereof.

     (b)  The words "claim", "action", "suit", or "proceeding" shall apply to 
all claims, actions, suits or proceedings (civil, criminal, administrative,
legislative, investigative or other, including appeals), actual or threatened,
and the words "liabilities" and "expenses" shall include, without limitation,
attorneys' fees, costs, judgments, amounts paid in settlement, fines, penalties
and other liabilities.

     (c)  No indemnification shall be provided to any person hereunder against 
any liabilities to the Trust or its Shareholders adjudicated to have been
incurred by reason of willful misfeasance, bad faith, gross negligence, or
reckless disregard of the duties involved in the conduct of such person's
office.

     (d)  The rights of indemnification herein provided may be insured against 
by policies maintained by the Trust, shall be severable, shall not affect any
other rights to which any Trustee, officer, employee or agent may now or
hereafter be entitled, shall continue as to a person who has ceased to be such
Trustee, officer, employee, or agent and shall inure to the benefit of the
heirs, executors and administrators of such a person; provided, however, that no
person may satisfy any right of indemnity or reimbursement granted herein except
out of the property of the Trust, and no other person shall be personally liable
to provide indemnity or reimbursement hereunder (except an insurer of surety of
person otherwise bound by contract).

     (e)  Expenses in connection with the preparation and presentation of a
defense to any claim, action, suit or proceeding of the character described in
paragraph (a) of this Section 4 may be paid by the Trust prior to final
disposition thereof upon receipt of a written undertaking by or on behalf of the
Trustee, officer, employee or agent to reimburse the Trust if it is ultimately
determined under this Section 4 that he is not entitled to indemnification.

                                  ARTICLE XII
                                 MISCELLANEOUS

     Section 1.  Trust is not a Partnership.  It is hereby expressly declared 
that a trust and not a partnership is created hereby.

     Section 2.  Trustee's Good Faith Action, Expert Advice, No Bond or Surety. 
The exercise by the Trustees of their powers and discretions hereunder in good
faith and with reasonable care under the circumstances then prevailing, shall be
binding upon everyone interested. Subject to the provisions of Article XI, the
Trustees shall not be liable for errors of judgment or mistakes of fact or law.
The Trustees may take advice of counsel or other experts with respect to the
meaning and operation of this Declaration of Trust, and, subject to the
provisions of Article XI, shall be under no liability for any act or omission in
accordance with such advice or for failing to follow such

                                       19
<PAGE>
 
advice.  The Trustees shall not be required to give any bond as such, nor any
surety if a bond is required.

     Section 3.  Establishment of Record Dates.  The Trustees may close the
Share transfer books of the Trust for a period not exceeding ninety (90) days
preceding the date of any meeting of Shareholders, or the date for the payment
of any dividend or the making of any distribution to Shareholders, or the date
for the allotment of rights, or the date when any change or conversion or
exchange of Shares shall go into effect; or in lieu of closing the Share
transfer books as aforesaid, the Trustees may fix in advance a date, not
exceeding ninety (90) days preceding the date of any meeting of Shareholders, or
the date for the payment of any dividend or the making of any distribution to
Shareholders, or the date for the allotment of rights, or the date when any
change or conversion or exchange of Shares shall go into effect, or the last day
on which the consent or dissent of Shareholders may be effectively expressed for
any purpose, as a record date for the determination of the Shareholders entitled
to notice of, and to vote at, any such meeting and any adjournment thereof, or
entitled to receive payment of any such dividend or distribution, or to any such
allotment of rights, or to exercise the rights in respect of any such change,
conversion or exchange of shares, or to exercise the right to give such consent
or dissent, and in such case, such Shareholders and only such Shareholders as
shall be Shareholders of record on the date so fixed shall be entitled to such
notice of, and to vote at, such meeting, or to receive payment of such dividend
or distribution, or to receive such allotment or rights, or to exercise such
rights, as the case may be, notwithstanding any transfer of any Shares on the
books of the Trust after any such date fixed as aforesaid.

     Section 4.  Termination of Trust.

     (a)  This Trust shall continue without limitation of time but subject to 
the provisions of paragraphs (b), (c) and (d) of this Section 4.

     (b)  The Trustees, with the approval of the holders of a majority of the 
outstanding Shares, may merge, consolidate, or sell and convey the assets of
the Trust including its goodwill to another trust or corporation organized under
the laws of any state of the United States for an adequate consideration which
may include the assumption of all outstanding obligations, taxes, and other
liabilities, accrued or contingent, of the Trust and which may include shares of
beneficial interest or stock of such trust or corporation.  Upon making
provision for the payment of all such liabilities by such assumption or
otherwise, the Trustees shall distribute the net proceeds of the transaction
ratably among the holdings of the Shares of the Trust then outstanding.

     (c)  Subject to a Majority Shareholder Vote, the Trustees may at any time 
sell and convert into money all the assets of the Trust. Upon making provision
for the payment of all outstanding obligations, taxes and other liabilities,
accrued or contingent, of the Trust, the Trustees shall distribute the remaining
assets of the Trust ratably among the holders of the outstanding Shares.

                                       20
<PAGE>
 
     (d)  Upon completion of the distribution of the remaining proceeds or the 
remaining assets as provided in paragraphs (b) and (c), the Trust shall be
discharged of any and all further liabilities and duties hereunder and the
right, title, and interest of all parties shall be canceled and discharged.

     Section 5.  Officers of the Trust, Filing of Copies, References, Headings. 
The Trust may maintain such offices in such locations as the Trustees may from
time-to-time determine. The original or a copy of this instrument and of each
declaration of trust supplemental hereto shall be kept at the office of the
Trust where it may be inspected by any Shareholder. A copy of this instrument
and of each supplemental declaration of trust shall be filed by the Trustees
with the Massachusetts Secretary of State, as well as any other governmental
office where such filings may from time-to-time be required. Anyone dealing with
the Trust may rely on a certificate by an officer of the Trust as to whether or
not any such supplemental declaration of trust has been made and as to any
matters in connection with the Trust hereunder, and with the same effect as if
it were the original, may rely on a copy certified by an officer of the Trust to
be a copy of this instrument or in any such supplemental declaration of trust.
In this instrument or in any such supplemental declaration of trust, references
to this instrument, and all expressions like "herein," "hereof" and "hereunder,"
shall be deemed to refer to this instrument as amended or affected by any such
supplemental declaration of trust. Headings are placed herein for convenience or
reference only, and in case of any conflict, the text of this instrument, rather
than the headings, shall control. This instrument may be executed in any number
of counterparts each of which shall be deemed an original.

     Section 6.  Applicable Law.  The Trust set forth in this instrument is
created under and is to be governed by and construed and administered according
to the laws of the Commonwealth of Massachusetts.  The Trust shall be of the
type commonly called a Massachusetts business trust, and without limiting the
provisions hereof, the Trust may exercise all powers which are ordinarily
exercised by such a trust.

     Section 7.  Amendments.  Prior to the initial issuance of Shares pursuant 
to the second sentence of Section 3 of Article III, a majority of the Trustees
then in office may amend or otherwise supplement this instrument by making a
declaration of trust supplemental hereto, which thereafter shall form a part
hereof. Subsequent to such initial issuance of Shares, if authorized by a
majority of the Trustees then in office and by a Majority Shareholder Vote, or
by any larger vote which may be required by applicable law or this declaration
of trust in any particular case, the Trustees shall amend or otherwise
supplement this instrument, by making a Declaration of Trust supplemental
hereto, which thereafter shall form a part hereof. Any such supplemental
declaration of trust shall be signed by at least a majority of the Trustees then
in office. Copies of the supplemental declaration of trust shall be filed as
specified in Section 5 of this Article XII.

     Section 8.  Conflicts with Law or Regulations.

     (a)  The provisions of this Declaration of Trust are severable, and if the 
Trustees determine, with the advice of counsel, that any such provision is in 
unresolvable conflict with the

                                       21
<PAGE>
 
1940 Act, with the provisions of the Internal Revenue Code  relating to the tax
treatment of a regulated investment company or other matters concerning
regulated investment companies, or with other applicable laws or regulations,
the conflicting provision shall be deemed never to have constituted a part of
this Declaration of Trust; provided, however, that such determination shall not
affect any of the remaining provisions hereof nor tender invalid or improper any
action taken or omitted prior to such determination.

     (b)  If any provision of this Declaration of Trust shall be held invalid or
unenforceable in any jurisdiction, such invalidity or unenforceability shall not
attach to such provision in any other jurisdiction or any other provision hereof
in any jurisdiction.

     Section 9.  Use of Name.  The Trustees of the Trust acknowledge that, in 
consideration of its assumption of certain expenses of formation of the Trust,
Calvert Asset Management Company, Inc., has reserved for itself the rights to
the name "ARIEL GROWTH FUND" (or any similar name) and that use by the Trust of
such name shall continue only with the continuing consent of Calvert Asset
Management Company, Inc., which consent may be withdrawn at any time, effect
immediately, upon written notice thereof to the trust.

     IN WITNESS WHEREOF, the undersigned have executed this instrument on the 
date first written above.

                                   ARTICLE I
                                  SHAREHOLDERS


     Section 1.  Meetings.  Meetings of the Shareholders shall be held at the
principal offices of the Trust in Washington. D.C., or at such place within or
without the Commonwealth of Massachusetts and on such dates and at such times as
the Trustees shall designate.

     Section 2.  Notice of Meetings.  Notice of all meetings of the
Shareholders, stating the time, place, and purposes of the meeting, shall be
given by the Trustees by mail to each shareholder at his address as recorded
with the Trust at least ten (10) days and not more than ninety (90) days before
the meeting.  Any adjourned meeting may be held as adjourned without further
notice.  No notice need be given to any Shareholder who shall have failed to
inform the Trust of his current address or if a written waiver of notice,
executed before or after the meeting by the Shareholder or his attorney
thereunto authorized, is filed with the records of the meeting.

     Section 3.  Record Date for Meetings and Other Purposes.  For the purpose
of determining the Shareholders who are entitled to notice of and to vote at any
meeting, including any adjournment thereof, or who are entitled to participate
in any distribution, or for the purpose of any other action, the Trustees may
from time-to-time close the transfer books, the Trustees may fix a date not more
than ninety (90) days prior to the date of any meeting of Shareholders or
distribution or other action as a record date for the determination of the
persons to be treated as shareholders governed by the Declaration of Trust.

     Section 4.  Proxies.  At any meeting of Shareholders, any holder of Shares
entitled to vote thereat may vote either in person or by proxy, provided that no
proxy shall be voted at any meeting unless it shall have been placed on file
with the Secretary, or with such other officer or agent of the Trust as the
Secretary may direct, for verification prior to the time at which such vote
shall be taken.  Pursuant to a resolution of a majority of the Trustees, proxies
may be solicited in the name of one or more Trustees or one or more officers of
the Trust. Only Shareholders of record shall be entitled to vote.  Each full
share shall be entitled to one vote, and fractional Shares shall be entitled to
a vote of such fraction.  When any Share is held jointly by several persons, any
one of them may vote at any meeting in person or by proxy in respect of such
Share, but if more than one of them shall be present at such meeting in person
or by proxy, and such joint owners or their proxies disagree as to any vote to
be cast such vote shall not be received in respect to such Share.  A proxy
purporting to be executed by or on behalf of a Shareholder shall be deemed valid
unless challenged at or prior to its exercise, and the burden of proving
invalidity shall rest on the
<PAGE>
 
challenger.  If the holder of any such Share is a minor or a person of unsound
mind, and subject to guardianship or to the legal control of any other person as
regards the charge or management of such Share, he may vote by his guardian or
such other person appointed or having such control, and such vote may be given
in person or by proxy.

     Section 5.  Inspection of Records.  The records, accounts and books of the
Trust shall be open to inspection by shareholders to the same extent as is
permitted shareholders of a Massachusetts business corporation.

     Section 6.  Action without Meeting.  Any action which may be taken by
Shareholders may be taken without a meeting if all shareholders entitled to vote
on the matter consent to the action in writing and the written consents are
filed with the records of the meeting of Shareholders.  Such consents shall be
treated for all purposes as a vote taken at a meeting of shareholders.

                                   ARTICLE II
                                    TRUSTEES

     Section 1.  The Trustees.  The Trust shall have six (6) Trustees, unless
and until such number be changed by amendment of the By-Laws or by resolution of
the Trustees.  The term of office of each Trustee shall expire upon the election
of a Successor Trustee at a meeting of Shareholders.

     Section 2.  Meeting of Trustees.  The Trustees may in their discretion
provide for regular or stated meetings of the Trustees.  Notice of regular or
stated meetings need not be given.  Meetings of the Trustees other than regular
or stated meetings shall be held whenever called by the president, or by one of
the Trustees, at the time being in office.  Notice of the time and place of each
meeting other than regular or stated meetings shall be given by the Secretary or
Assistant Secretary or by the officer or Trustee calling the meeting and shall
be mailed to each Trustee at least two days before the meeting, or shall be
telegraphed, cabled, or personally delivered to him at least one day before the
meeting.  Notice by telephone shall constitute personal delivery for these
purposes.  Notice may, however, be waived by any Trustee before or after any
meeting.  Neither the business to be transacted at, nor the purpose of any
meeting of the Trustees need to be stated in the notice or waiver of notice of
such meeting, and no notice need be given of action proposed to be taken by
unanimous written consent.  The attendance of a Trustee at a meeting shall
constitute a waiver of notice of such meeting except where a Trustee attends a
meeting for the express purpose of objecting to the transaction of any business
on the ground that the meeting has not been lawfully called or convened.  The
Trustees may meet by means of a telephone conference circuit or similar
communications equipment, by means of which all persons participating in the
meeting can hear each other, which telephone conference meeting shall be deemed
to have been held at a place designated by the Trustees at the meeting.
Participation in a telephone conference meeting shall constitute presence in
person at such

                                       2
<PAGE>
 
meeting.  Any action required or permitted to be taken at any meeting of the
Trustees may be taken by the Trustees without a meeting if all the Trustees
consent to the action in writing and the written consents are filed with the
records of the Trustees' meetings.  Such consents shall be treated as a vote for
all purposes.

     Section 3.  Quorum and Vote.  A majority of the Trustees shall be present
in person at any regular or special meeting of the Trustees in order to
constitute a quorum for the transaction of business at such meeting and (except
as otherwise required by law, the Declaration of Trust or these By-Laws) the act
of a majority of the Trustees present at any meeting at which the quorum is
present shall be the act of the Trustees.  In the absence of a quorum, a
majority of the Trustees present may adjourn the meeting from time-to-time until
a quorum shall be present.  Notice of any adjourned meeting need not be given.

     Section 4.  Compensation of Trustees.  The compensation of the Trustees
shall be fixed from time to time by the Trustees.  No Trustee shall be precluded
from serving the Trust in any other capacity, as an officer, agent or otherwise,
and receiving compensation therefor.

                                  ARTICLE III
                                   COMMITTEES

     Section 1.  Executive and Other Committees.  The Trustees by vote of a
majority of all the Trustees may elect from their own number an Executive
Committee, to consist of not less than two (2) members to hold office at the
pleasure of the Trustees, which shall have the power to conduct the current and
ordinary business of the Trust while the Trustees are not in session and such
other powers of the Trustees as the Trustees may, from time-to-time, delegate to
them except those powers which by law, the Declaration of Trust, or these By-
Laws they are prohibited from delegating.  The Trustees may also elect from
their own number other Committees from time-to-time, the number composing such
Committees, the powers conferred upon the same (subject to the same limitations
as the Executive Committee) and the term of membership of such Committees to be
determined by the Trustees.  The Trustees may designate a Chairman of any such
Committee; in the absence of such a designation, the Committee may elect its own
Chairman.

     Section 2.  Meeting, Quorum and Manner of Acting.  The Trustees may (1)
provide for stated meetings of any Committees, (2) specify the manner of calling
and notice required for special meetings of any Committee, (3) specify the
number of members of a Committee required to constitute a quorum and the number
of members of a Committee required to exercise specified powers delegated to
such Committee, (4) authorize the making of decisions to exercise specified
powers by written assent of the requisite number of members of a Committee
without a meeting, and (5) authorize the members of a Committee to meet by means
of a telephone conference circuit.

     All Committees shall keep regular minutes of their meetings and records of
decisions taken without a meeting and cause them to be recorded in a book
designated for that purpose and kept

                                       3
<PAGE>
 
in the office of the Trust.  All action by Committees shall be reported to the
Trustees at their meeting next succeeding such action.

     Section 3.  Compensation.  The members of any duly appointmented Committee
shall receive such compensation and/or fees as, from time-to-time, may be fixed
by the Trustees.

                                   ARTICLE V
                                    OFFICERS

     Section 1.  General Provisions.  The officers of the Trust shall be a
President and a Secretary who shall be elected by the Trustees.  The Trustees
may elect or appoint such other officers or agents as the business of the Trust
may require, including a Chairman, a Treasurer, one or more Vice Presidents, one
or more Assistant Secretaries, and one or more Assistant Treasurers.  The
Trustees may delegate to any officer or Committee the power to appoint any
subordinate officers or agents.

     Section 2.  Term of Office and Qualifications.  Except as otherwise
provided by law, the Declaration of Trust or these By-Laws, the President and
the Secretary shall each hold office until his successor shall have been duly
elected and qualified, and all other officers shall hold office at the pleasure
of the Trustees.  Any two or more of the officers may be held by the same
person, except that the same person may not be both President and Secretary.
The Chairman, if there be such an officer, and the President shall be Trustees,
but no other officer of the Trust need be a Trustee.

     Section 3.  Removal.  The Trustees, at any regular or special meeting of
the Trustees, may remove any officer with or without cause by a vote of the
majority of the Trustees.  Any officer or agent appointed by any officer or
Committee may be removed with or without cause by such appointing officer or
Committee.

     Section 4.  Bonds and Surety.  Any officer may be required by the Trustees
to be bonded for the faithful performance of his duties in such amount and with
such sureties as the Trustees may determine.

     Section 5.  Chairman, President, and Vice Presidents.  The Chairman, if
there be such an officer, shall, if present, preside at all meetings of the
Shareholders and of the Trustees and shall exercise and perform such other
powers and duties as may be from time to time assigned to him by the Trustees.
Subject to such supervisory powers, if any, as may be given by the Trustees to
the Chairman, the President shall be the chief executive officer of the Trust
and, subject to the control of the Trustees, shall have general supervision,
direction and control of the business of the Trust and of its employees and
shall exercise such general powers of management as are usually vested in the
office of President of a corporation.  In the absence of the Chairman, the
President shall preside at all meetings of the Shareholders and of the Trustees.
The President shall have the

                                       4
<PAGE>
 
power in the name and on behalf of the Trust to grant, issue, execute or sign
any and all documents, contracts, agreements, deeds, mortgages, proxies,
powers of attorney or other instruments as may be deemed advisable or necessary
in furtherance of the interests of the Trust. The President shall have the power
to employ attorneys and counsel for the Trust and to employ such subordinate
officers, agents, clerks and employees as he may find necessary to transact the

hereunder by the Adviser/Manager, the Trust shall pay to the Adviser/Manager out
of the assets of the respective Funds within ten (10) days after the last day of
each calendar month a fee calculated on the basis of average daily net assets at
the annual rates for the respective Funds set forth in one or more written
addenda to this Agreement executed by both parties.

Such fee shall be computed and accrued daily.  Upon termination of this
Agreement as to any Fund before the end of any calendar month, the fee of that
Fund for such period shall be prorated. For purposes of calculating the fee of
the Adviser/Manager, the daily value of each Fund's net assets shall be computed
by the same method as the Trust uses to compute the value of net assets in
connection with the determination of the net asset value of each Fund's shares.

          b.  The Adviser/Manager reserves the right (i) to waive all or a part
of its fee and (ii) to make payments to brokers and dealers from the resources
of the Adviser/Manager in consideration of their promotional or administrative
services.

     5.  Expense Guarantee.  The Adviser/Manager hereby agrees to reimburse the
Trust if and to the extent that the aggregate operating expenses of any Fund in
any given fiscal year, including the fee paid to the Adviser/Manager, but
excluding distribution plan expenses, brokerage, taxes, interest, and
extraordinary expenses, are in excess of 1.5% of the first $30 million of such
Fund's average daily net assets and 1% of such assets in excess of $30 million.
If for any month a Fund's expenses are in excess of such limitation, then the
Adviser/Manager shall promptly and fully reimburse the Trust for such excess,
either by waiving the management fee or by direct cash payment or both.  If for
any month a Fund's actual expenses are less than the applicable percentage
limitations and the Adviser/Manager has for previous months during the current
fiscal year reimbursed the Trust for excess expenses, then, to the extent
maximum permissible expenses for the current month exceed actual expenses for
that month, the Adviser/Manager shall at the end of such month recoup from the
Trust all such previous reimbursements.

     6.  Activities of the Adviser/Manager.  The services of the Adviser/Manager
hereunder are not to be deemed exclusive, and the Adviser/Manager shall be free
to render similar services to others. It is understood that Trustees and
officers of the Trust are or may become interested in the Adviser/Manager as
stockholders, officers or otherwise, and that stockholders and officers of the
Adviser/Manager are or may become similarly interested in the Trust, and that
the Adviser/Manager may become interested in the Trust as a shareholder or
otherwise.

     7.  Use of Names.  The Trust shall not use the name "Ariel" or the name of
the Adviser/Manager in any prospectus, sales literature or other material
relating to the Trust or to any Fund in any manner not approved prior thereto by
the Adviser/Manager; provided, however, that the Adviser/Manager shall approve
all uses of its name which merely refer in accurate terms to its appointment
hereunder or which are required by the SEC or a State Securities Commission;
and, provided, further, that in no event shall such approval be unreasonably
withheld. The Adviser/Manager shall not use the name of the Trust or of any Fund
in any material relating to the Adviser/Manager in any manner not approved prior
thereto by the Trust; provided, however, that the Trust shall approve all uses
of its name and of the name of any Fund which merely refer in accurate terms to
the appointment of the Adviser/Manager hereunder or which are required by the
SEC or a State Securities Commission; and, provided further, that in no event
shall such approval be unreasonably withheld.

     8.  Liability of the Adviser/Manager.  Absent willful misfeasance, bad 
faith, gross negligence, or reckless disregard of obligations or duties
hereunder on the part of the Adviser/Manager, the Adviser/Manager shall not be
subject to liability to the Trust or to any shareholder of the Trust for any act
or omission in the course of, or connected with, rendering services hereunder or
for any losses that may be sustained in the purchase, holding or sale of any
security.

     9.  Limitation of Trust's Liability.  The Adviser/Manager acknowledges that
it has received notice of and accepts the limitations upon the Trust's liability

<PAGE>
 
Declaration of Trust.  The Adviser/Manager agrees that the Trust's obligations
hereunder in any case shall be limited to the Trust and to its assets and that
the Adviser/Manager shall not seek satisfaction of any such obligation from the
shareholders of the Trust nor from any Trustee, officer, employee or agent of
the Trust.

     10.  Force Majeure.  The Adviser/Manager shall not be liable for delays or 
errors occurring by reason of circumstances beyond its control, including but
not limited to acts of civil or military authority, national emergencies, work
stoppages, fire, flood, catastrophe, acts of God, insurrection, war, riot, or
failure of communication or power supply. In the event of equipment breakdowns
beyond its control, the Adviser/Manager shall take reasonable steps to minimize
service interruptions but shall have no liability with respect thereto.

     11.  Renewal, Termination and Amendment.  This Agreement shall be effective
as to a Fund on the date of initial effectiveness stated in the addendum with
respect to that Fund and continue with respect to the Fund for an initial term
specified in such addendum unless sooner terminated as hereinafter provided.
Upon effectiveness the Agreement shall supersede all prior agreements between
the parties providing for investment advisory and administrative services for
the Fund. It shall continue from year to year thereafter as long as its
continuance with respect to the Fund is approved annually in accordance with the
1940 Act. This Agreement may be terminated as to any Fund at any time, without
payment of any penalty, by the Trust's Board of Trustees, or by a vote of the
majority of the outstanding voting securities of such Fund upon 60 days' prior
written notice to the Adviser/Manager and by the Adviser/Manager upon 60 days'
prior written notice to the Trust. This Agreement may be amended as to a Fund at
any time by the parties, subject to approval by the Trust's Board of Trustees
and, if required by law or applicable SEC regulations, a vote of a majority of
the outstanding voting securities of such Fund. This Agreement shall terminate
automatically in the event of its assignment. The terms "assignment" and "vote
of a majority of the outstanding voting securities" shall have the meaning set
forth in the 1940 Act.

     12.  Funds.  As of the date of this Agreement, the Trust has two series of 
shares, the Growth Fund and Appreciation Fund. This Agreement shall apply to and
be effective as to each such series and any series hereafter created by the
Trust for which this Agreement has been approved in the manner required by the
1940 Act, provided that there is a written addendum to this Agreement executed
by both parties which identifies such series as a Fund to be managed pursuant to
this Agreement, specifies the fee payable to the Adviser/Manager with respect to
such series, and states the initial effective and termination dates of this
Agreement with respect to each Fund.

     13.  Severability.  If any provision of this Agreement shall be held or 
made invalid by a court decision, statute, rule or otherwise, the remainder of 
this Agreement shall not be affected thereby.

                                       5

     14.  Miscellaneous.  Each party agrees to perform such further actions and

hereof.  This Agreement shall be construed and enforced in accordance with and
governed by the laws of the State of Illinois. The captions in this Agreement

                             UNDERWRITING AGREEMENT


     UNDERWRITING AGREEMENT, made as of the sixteenth day of May, 1995, by and
between ARIEL DISTRIBUTORS, INC., an Illinois corporation (the "Distributor"),
and ARIEL GROWTH FUND, d/b/a ARIEL INVESTMENT TRUST, a Massachusetts business
trust (the "Trust").

     WHEREAS, the Trust is an open-end, diversified investment company
registered under the Investment Company Act of 1940 (the "1940 Act") and has
registered its shares for sale to the public under the Securities Act of 1933
(the "1933 Act") and various state securities laws;

     WHEREAS, the Trust wishes to retain the Distributor as the principal
underwriter in connection with the offering and sale of shares of the Trust (the
"Shares") and to furnish certain other services to the Trust as specified in
this Agreement;

     WHEREAS, this Agreement has been approved by a vote of the Trust's Board of
Trustees and certain trustees who are not interested persons of the Trust, in
conformity with the 1940 Act and the regulations thereunder; and

     WHEREAS, the Distributor is willing to act as principal underwriter and to
furnish such services on the terms and conditions hereinafter set forth;

     NOW, THEREFORE, in consideration of the promises and mutual covenants
herein contained, it is agreed as follows:

     1.  The Trust hereby appoints the Distributor as principal underwriter in
connection with the offering and sale of the Shares in jurisdictions wherein the
Shares may legally be sold, for the period and on the terms hereinafter set
forth.  The Distributor shall, as agent for the Trust, subject to applicable
federal and state law and the Trust's Declaration of Trust and By-laws, and in
accordance with the representations in each Fund's Prospectus and Statement of
Additional Information, as such documents may be amended from time to time: (a)
promote the Trust and the Funds; (b) enter into appropriate dealer agreements
with other registered broker-dealers and other persons or organizations
("Firms") to further distribution of the Shares; (c) solicit orders for the
purchase of the Shares subject to such terms and conditions as the Trust may
specify; (d) transmit promptly orders and payments for the purchase of Shares
and orders for the redemption of Shares to the Trust's transfer agent; and (e)
provide services to shareholders as agreed upon by the Trust. The Distributor
shall comply with all applicable federal and state laws and offer the Shares on
an agency or "best efforts" basis under which the Trust shall only issue such
Shares as are actually sold.

     2.  (a)  The Distributor may sell shares of the Trust directly to
investors.  In addition, the Distributor may sell shares of the Trust to or
through Firms in such manner, not inconsistent with the
<PAGE>
 
provisions hereof and the then effective Registration Statement of the Trust (as
hereinafter defined) under the 1933 Act, as the Distributor may determine from
time to time, provided that no Firm or other person shall be appointed or
authorized to act as agent of the Trust without the prior consent of the Trust,
and further provided that the Distributor, and not the Trust, will be
responsible for the payment of compensation to such Firms for such services.

     (b)  Shares of the Trust offered for sale or sold by the Distributor shall
be offered or sold at a price per share determined in accordance with the then
current Prospectus and Statement of Additional Information relating to the sale
of such Shares except as departure from such prices shall be permitted by the
rules and regulations of the Securities and Exchange Commission ("SEC").

     (c)  The Distributor will conform and will require each Firm to conform to
the provisions hereof and the Registration Statement under the 1933 Act with
respect to the public offering price, manner of sales and payment terms of the
Trust's shares, and neither the Distributor nor any such Firms shall withhold
the placing of purchase orders so as to make a profit thereby.

     3.  The compensation to be paid for the services performed and the
obligations assumed by the Distributor under this Agreement, if any, shall be
set forth in one or more written addenda to this Agreement executed by both
parties.

     4.  As used in this Agreement, the term "Registration Statement" shall mean
the registration statement most recently filed by the Trust with the Securities
and Exchange Commission and effective under the 1933 Act (including the related
Prospectus and Statement of Additional Information), as such Registration
Statement is amended by any amendments thereto at the time in effect, and the
terms "Prospectus" and "Statement of Additional Information" shall mean the form
of prospectus and Statement of Additional Information filed with respect to each
Fund as part of the Registration Statement.

     5.  The Distributor shall print and distribute to prospective investors
Prospectuses and Statements of Additional Information, and may print and
distribute such other sales literature, reports, forms, and advertisements in
connection with the sale of the Shares as comply with the applicable provisions
of federal and state law.  In connection with such sales and offers of sale, the
Distributor shall give only such information and make only such statements or
representations, and require any Firms with whom it enters into dealer
agreements to give only such information and make only such statements or
representations, as are contained in the Prospectus or Statement of Additional
Information of a Fund or in information furnished in writing to the Distributor
by the Trust.  The Trust shall not be responsible in any way for any other
information, statements or representations given or made by the Distributor or
by any Firms or other persons acting as representatives or agents of the
Distributor or of any such Firms or other persons.

     6.  The Trust shall assume and pay all charges and expenses of its
operations not specifically assumed or otherwise to be provided by the
Distributor under this Agreement.  The Trust will pay or cause to be paid
expenses (including the fees and disbursements of its own counsel) and all taxes
and fees payable to the federal, state or other governmental agencies on account
of the

                                       2
<PAGE>
 
registration or qualification of securities issued by the Trust or otherwise.
The Trust will also pay or cause to be paid expenses incident to the issuance of
shares of beneficial interest, such as the cost of share certificates, issue
taxes, and fees of the transfer agent.  The Distributor will pay all expenses
(other than expenses which one or more Firms may bear pursuant to any agreement
with the Distributor) incident to the sale and distribution of the shares issued
or sold hereunder including, without limiting the generality of the foregoing,
all expenses of printing and distributing any Prospectus or Statement of
Additional Information and of preparing, printing and distributing or
disseminating any other literature, advertising and selling aids in connection
with the offering of the shares for sale (except that such expenses shall not
include expenses incurred by the Trust in connection with the preparation,
typesetting, printing and distribution of any Registration Statement, Prospectus
and Statement of Additional Information or report or other communication to
shareholders in their capacity as such), expenses of advertising in connection
with such offering, compensation to the Firms referred to herein and sales
compensation to Distributor's registered representatives.

     7.  The Trust agrees to indemnify, defend and hold the Distributor, its
several officers and directors, and any person who controls the Distributor
within the meaning of Section 15 of the 1933 Act, free and harmless from and
against any and all claims, demands, liabilities and expenses (including the
cost of investigating or defending such claims, demands or liabilities and any
counsel fees incurred in connection therewith) which the Distributor, its
officers or directors, or any such controlling person may incur, under the 1933
Act or under common law or otherwise, arising out of or based upon any alleged
untrue statement of a material fact contained in the Registration Statement,
Prospectus or Statement of Additional Information of a Fund or arising out of or
based upon any alleged omission to state a material fact required to be stated
therein or necessary to make the statements therein not misleading, provided
that in no event shall anything contained in this Agreement be construed so as
to protect the Distributor against any liability to the Trust or its
shareholders to which the Distributor would otherwise be subject by reason of
willful misfeasance, bad faith, or gross negligence, in the performance of its
duties, or by reason of its reckless disregard of its obligations and duties
under this Agreement.

     8.  The Distributor agrees to indemnify, defend and hold the Trust, its
several officers and directors, and any person who controls the Trust within the
meaning of Section 15 of the 1933 Act, free and harmless from and against any
and all claims, demands, liabilities and expenses (including the cost of
investigating or defending such claims, demands or liabilities and any counsel
fees incurred in connection therewith) which the Trust, its officers or
directors, or any such controlling person may incur, under the 1933 Act or under
common law or otherwise, arising out of or based upon any alleged untrue
statement or a material fact contained in information furnished in writing by
the Distributor to the Trust for use in the Registration Statement, Prospectus
or Statement of Additional Information of a Fund or arising out of or based upon
any alleged omission to state a material fact in connection with such
information required to be stated in the Registration Statement, Prospectus or
Statement of Additional Information or necessary to make such information not
misleading.

     9.  The Trust reserves the right at any time to withdraw any or all
offerings of the Shares by written notice to the Distributor at its principal
office.

                                       3
<PAGE>
 
     10.  The Distributor is an independent contractor and shall be agent for
the Trust only in respect to the offer, sale and redemption of the Shares.

     11.  The services of the Distributor to the Trust under this Agreement are
not to be deemed exclusive, and the Distributor shall be free to render similar
services or other services to others so long as its services hereunder are not
impaired thereby.

     12.  The Distributor acknowledges that it has received notice of and
accepts the limitations upon the Trust's liability set forth in Article XI of
its Declaration of Trust.  The Distributor agrees that the Trust's obligations
hereunder in any case shall be limited to the Trust and to its assets (or the
assets of the applicable Fund) and that the Distributor shall not seek
satisfaction of any such obligation from the shareholders of the Trust nor from
any Trustee, officer, employee or agent of the Trust.

     13.  The Trust shall not use the name of the Distributor in any Prospectus,
Statement of Additional Information, sales literature or other material relating
to the Trust in any manner not approved prior thereto by the Distributor;
provided, however, that the Distributor shall approve all uses of its name which
merely refer in accurate terms to its appointment hereunder or which are
required by the SEC or applicable state securities commissions; and, provided
further, that in no event shall such approval be unreasonably withheld.  The
Distributor shall not use the name of the Trust or of any Fund in any material
relating to the Distributor in any manner not approved prior thereto by the
Trust; provided, however that the Trust shall approve all uses of its name and
the name of any Fund which merely refer in accurate terms to the appointment of
the Distributor hereunder or which are required by the SEC or a state securities
commission; and, provided further, that in no event shall such approval be
unreasonably withheld.

     14.  The Distributor shall prepare written reports for the Board of
Trustees of the Trust on a quarterly basis showing information concerning
services provided and expenses incurred which are related to this Agreement and
such other information as from time to time shall be reasonably requested by the
Trust's Board of Trustees.

     15.  This Agreement shall be effective on May 16, 1995 and continue for an
initial term ending January 31, 1997 unless sooner terminated as hereinafter
provided.  It shall continue from year to year thereafter as long as its
continuance is approved annually in accordance with the 1940 Act and the
regulations thereunder.  This Agreement may be terminated at any time by either
party upon 60 or more days prior written notice to the other party.  This
Agreement may be amended as to a Fund at any time by the parties, subject to
approval by the Trust's Board of Trustees and, if required by law or applicable
SEC regulations, a vote of a "majority of the outstanding voting securities" of
such Fund, as defined in the 1940 Act and any regulations thereunder.  This
Agreement shall be binding on the successors and assigns of each party,
provided, however, that this Agreement shall terminate automatically in the
event of its "assignment", as defined in the 1940 Act and any regulations
thereunder.

                                       4

     16.  Each party agrees to perform such further actions and execute such
further documents as are necessary to effectuate the purposes hereof.  This
Agreement shall be construed and enforced in accordance with and governed by the
laws of the State of Illinois.

                               -----------------

              legal, valid and binding obligation of Custodian, enforceable in
              accordance with its terms.

3.   DUTIES AND RESPONSIBILITIES OF CUSTODIAN.

     A.   Delivery of Assets

          Except as permitted by the 1940 Act, Fund will deliver or cause to be
          delivered to Custodian on the effective date of this Agreement, or as
          soon thereafter as practicable, and from time to time thereafter, all
          portfolio securities acquired by it and monies then owned by it or
          from time to time coming into its possession during the time this
          Agreement shall continue in effect. Custodian shall have no
          responsibility or liability whatsoever for or on account of securities
          or monies not so delivered.

                                       2
<PAGE>
 
     B.   Delivery of Accounts and Records

          Fund shall turn over or cause to be turned over to Custodian all of
          the Fund's relevant accounts and records previously maintained.
          Custodian shall be entitled to rely conclusively on the completeness
          and correctness of the accounts and records turned over to it, and
          Fund shall indemnify and hold Custodian harmless of and from any and
          all expenses, damages and losses whatsoever arising out of or in
          connection with any error, omission, inaccuracy or other deficiency of
          such accounts and records or in the failure of Fund to provide, or to
          provide in a timely manner, any accounts, records or information
          needed by the Custodian to perform its functions hereunder.

     C.   Delivery of Assets to Third Parties

          Custodian will receive delivery of and keep safely the assets of Fund
          delivered to it from time to time segregated in a separate account,
          and if Fund is comprised of more than one portfolio of investment
          securities (each a "Portfolio") Custodian shall keep the assets of
          each Portfolio segregated in a separate account. Custodian will not
          deliver, assign, pledge or hypothecate any such assets to any person
          except as permitted by the provisions of this Agreement or any
          agreement executed by it according to the terms of Section 3.S. of
          this Agreement. Upon delivery of any such assets to a subcustodian
          pursuant to Section 3.S. of this Agreement, Custodian will create and
          maintain records identifying those assets which have been delivered to
          the subcustodian as belonging to the Fund, by Portfolio if applicable.
          The Custodian is responsible for the safekeeping of the securities and
          monies of Fund only until they have been transmitted to and received
          by other persons as permitted under the terms

                                       3
<PAGE>
 
          of this Agreement, except for securities and monies transmitted to
          subcustodians appointed under Section 3.S. of this Agreement, for
          which Custodian remains responsible to the extent provided in Section
          3.S. hereof. Custodian may participate directly or indirectly through
          a subcustodian in the Depository Trust Company (DTC), Treasury/Federal
          Reserve Book Entry System (Fed System), Participant Trust Company
          (PTC) or other depository approved by the Fund (as such entities are
          defined at 17 CFR Section 270.17f-4(b)) (each a "Depository" and
          collectively, the "Depositories").

     D.   Registration of Securities

          The Custodian shall at all times hold registered securities of the
          Fund in the name of the Custodian, the Fund, or a nominee of either of
          them, unless specifically directed by instructions to hold such
          registered securities in so-called "street name," provided that, in
          any event, all such securities and other assets shall be held in an
          account of the Custodian containing only assets of the Fund, or only
          assets held by the Custodian as a fiduciary or custodian for
          customers, and provided further, that the records of the Custodian at
          all times shall indicate the Fund or other customer for which such
          securities and other assets are held in such account and the
          respective interests therein. If, however, the Fund directs the
          Custodian to maintain securities in "street name," notwithstanding
          anything contained herein to the contrary, the Custodian shall be
          obligated only to utilize its best efforts to timely collect income
          due the Fund on such securities and to notify the Fund of relevant
          corporate actions including, without limitation, pendency of calls,
          maturities, tender or exchange offers. All securities, and

                                       4
<PAGE>
 
          the ownership thereof by Fund, which are held by Custodian hereunder,
          however, shall at all times be identifiable on the records of the
          Custodian. The Fund agrees to hold Custodian and its nominee harmless
          for any liability as a shareholder of record of securities held in
          custody.

     E.   Exchange of Securities

          Upon receipt of instructions as defined herein in Section 4.A,
          Custodian will exchange, or cause to be exchanged, portfolio
          securities held by it for the account of Fund for other securities or
          cash issued or paid in connection with any reorganization
          recapitalization, merger, consolidation, split-up of shares, change of
          par value, conversion or otherwise, and will deposit any such
          securities in accordance with the terms of any reorganization or
          protective plan. Without instructions, Custodian is authorized to
          exchange securities held by it in temporary form for securities in
          definitive form, to effect an exchange of shares when the par value of
          the stock is changed, and, upon receiving payment therefor, to
          surrender bonds or other securities held by it at maturity or when
          advised of earlier call for redemption, except that Custodian shall
          receive instructions prior to surrendering any convertible security.

     F.   Purchases of Investments of the Fund - Other Than Options and Futures

          Fund will, on each business day on which a purchase of securities
          (other than options and futures) shall be made by it, deliver to
          Custodian instructions which shall specify with respect to each such
          purchase:

          1.  If applicable, the name of the Portfolio making such purchase;

          2.  The name of the issuer and description of the security;

                                       5
<PAGE>
 
          3.  The number of shares and the principal amount purchased, and 
              accrued interest, if any;

          4.  The trade date;

          5.  The settlement date;

          6.  The purchase price per unit and the brokerage commission, taxes
              and other expenses payable in connection with the purchase;

          7.  The total amount payable upon such purchase;

          8.  The name of the person from whom or the broker or dealer through 
              whom the purchase was made; and

          9.  Whether the security is to be received in certificated form or 
              via a specified Depository.

     In accordance with such instructions, Custodian will pay for out of monies
     held for the account of Fund, but only insofar as such monies are available
     for such purpose, and receive the portfolio securities so purchased by or
     for the account of Fund, except that Custodian may in its sole discretion
     advance funds to the Fund which may result in an overdraft because the
     monies held by the Custodian on behalf of the Fund are insufficient to pay
     the total amount payable upon such purchase. Except as otherwise instructed
     by Fund, such payment shall be made by the Custodian only upon receipt of
     securities: (a) by the Custodian; (b) by a clearing corporation of a
     national exchange of which the Custodian is a member; or (c) by a
     Depository. Notwithstanding the foregoing, (i) in the case of a repurchase

              resulting from the actions or omissions of any Depository only to
              the same extent such Depository is responsible to Custodian.

          2.  Notwithstanding any other provisions of this Agreement, Fund's
              foreign securities (as defined in Rule 17f-5(c)(1) under the 1940
              Act) and Fund's cash or cash equivalents, in amounts deemed by the
              Fund to be reasonably necessary to effect Fund's foreign
              securities transactions, may be held in the custody of one or more
              banks or trust companies acting as subcustodians, and thereafter,
              pursuant to a written contract or contracts as approved by Fund's
              Board of Directors, may be transferred to accounts maintained by
              any such subcustodian with eligible foreign custodians, as defined
              in Rule 17f-5(c)(2). Custodian shall be responsible to the Fund
              for any loss, damage or expense suffered or incurred by the Fund
              resulting from the actions or omissions of any foreign
              subcustodians or a domestic subcustodian contracting with such
              foreign subcustodians only to the same extent such domestic
              subcustodian is responsible to the Custodian.

     T.   Accounts and Records Property of Fund

          Custodian acknowledges that all of the accounts and records maintained
          by Custodian pursuant to this Agreement are the property of Fund, and
          will be made available to Fund for inspection or reproduction within a
          reasonable period of time upon demand. Custodian will assist Fund's
          independent auditors, or upon approval of Fund, or upon demand, any
          regulatory body, in any requested review of Fund's accounts and
          records but shall be reimbursed by Fund for all expenses and employee
          time invested in any such review outside of routine and normal
          periodic reviews. Upon receipt from Fund of the necessary information
          or instructions, Custodian will supply information from the books and
          records it maintains for Fund that Fund needs for tax returns,
          questionnaires, periodic reports to shareholders and such other
          reports and information requests as Fund and Custodian shall agree
          upon from time to time.

     U.   Adoption of Procedures

          Custodian and Fund may from time to time adopt procedures as they
          agree upon, and Custodian may conclusively assume that no procedure
          approved or directed by Fund or its accountants or other advisors
          conflicts with or violates any requirement of its prospectus, Trust
          Agreement, Bylaws, any applicable law, rule or regulation, or any
          order, decree or agreement by which Fund may be bound. Fund will be
          responsible to notify Custodian of any changes in statutes,
          regulations, rules, requirements or policies which might necessitate
          changes in Custodian's responsibilities or procedures.

     V.   Overdrafts

                                       20
<PAGE>
 
          If Custodian shall in its sole discretion advance funds to the account
          of the fund which results in an overdraft in any Account because the
          monies held therein by Custodian on behalf of the Fund are
          insufficient to pay the total amount payable upon a purchase of
          securities as specified in Fund's instructions or for some other
          reason, the amount of the overdraft shall be payable by the Fund to
          Custodian upon demand together with the overdraft charge set forth on
          the then-current Fee Schedule from the date advanced until the date of
          payment. Fund hereby grants Custodian a lien on and security interest
          in the assets of the Fund to secure the full amount of any outstanding
          overdraft and related overdraft charges.

     W.   Exercise of Rights; Tender Offers

          Upon receipt of instructions, the Custodian shall: (a) deliver
          warrants, puts, calls, rights or similar securities to the issuer or
          trustee thereof, or to the agent of such issuer or trustee, for the
          purpose of exercise or sale, provided that the new securities, cash or
          other assets, if any, are to be delivered to the Custodian; and (b)
          deposit securities upon invitations for tenders thereof, provided that
          the consideration for such securities is to be paid or delivered to
          the Custodian or the tendered securities are to be returned to the
          Custodian.

4.   INSTRUCTIONS.

     A.   The term "instructions", as used herein, means written (including
          telecopied or telexed) or oral instructions which Custodian reasonably
          believes were given by a designated representative of Fund. Fund shall
          deliver to Custodian, prior to delivery of any assets to Custodian and
          thereafter from time to time as changes therein are

                                       21
<PAGE>
 
          necessary, written instructions naming one or more designated
          representatives to give instructions in the name and on behalf of
          Fund, which instructions may be received and accepted by Custodian as
          conclusive evidence of the authority of any designated representative
          to act for Fund and may be considered to be in full force and effect
          (and Custodian will be fully protected in acting in reliance thereon)
          until receipt by Custodian of notice to the contrary. Unless such
          written instructions delegating authority to any person to give
          instructions specifically limit such authority to specific matters or
          require that the approval of anyone else will first have been
          obtained, Custodian will be under no obligation to inquire into the
          right of such person, acting alone, to give any instructions
          whatsoever which Custodian may receive from such person. If Fund fails
          to provide Custodian any such instructions naming designated
          representatives, any instructions received by Custodian from a person
          reasonably believed to be an appropriate representative of Fund shall
          constitute valid and proper instructions hereunder.

     B.   No later than the next business day immediately following each oral 
          instruction, Fund will send Custodian written confirmation of such
          oral instruction. At Custodian's sole discretion, Custodian may record
          on tape, or otherwise, any oral instruction whether given in person or
          via telephone, each such recording identifying the parties, the date
          and the time of the beginning and ending of such oral instruction.

5.   LIMITATION OF LIABILITY OF CUSTODIAN.

     A.   Custodian shall at all times use reasonable care and due diligence 
          and act in good faith in performing its duties under this Agreement.
          Custodian shall not

                                       22
<PAGE>
 
          be responsible for, and the Fund shall indemnify and hold Custodian
          harmless from and against, any and all losses, damages, costs,
          charges, counsel fees, payments, expenses and liability which may be
          asserted against Custodian, incurred by Custodian or for which
          Custodian may be held to be liable, arising out of or attributable to:

          1.  All actions taken by Custodian pursuant to this Agreement or any
              instructions provided to it hereunder, provided that Custodian has
              acted in good faith and with due diligence and reasonable care;
              and

          2.  The Fund's refusal or failure to comply with the terms of this
              Agreement (including without limitation the Fund's failure to pay
              or reimburse Custodian under this Indemnification provision), the
              Fund's negligence or willful misconduct, or the failure of any
              representation or warranty of the Fund hereunder to be and remain
              true and correct in all respects at all times.

     B.   Custodian may request and obtain at the expense of Fund the advice
          and opinion of counsel for Fund or of its own counsel with respect to
          questions or matters of law, and it shall be without liability to Fund
          for any action taken or omitted by it in good faith, in conformity
          with such advice or opinion. If Custodian reasonably believes that it
          could not prudently act according to the instructions of the Fund or
          the Fund's accountants or counsel, it may in its discretion, with
          notice to the Fund, not act according to such instructions.

                                       23
<PAGE>
 
     C.   Custodian may rely upon the advice and statements of Fund, Fund's
          accountants and officers or other authorized individuals, and other
          persons believed by it in good faith to be expert in matters upon
          which they are consulted, and Custodian shall not be liable for any
          actions taken, in good faith, upon such advice and statements.

     D.   If Fund requests Custodian in any capacity to take any action which
          involves the payment of money by Custodian, or which might make it or
          its nominee liable for payment of monies or in any other way,
          Custodian shall be indemnified and held harmless by Fund against any
          liability on account of such action; provided, however, that nothing
          herein shall obligate Custodian to take any such action except in its
          sole discretion.

     E.   Custodian shall be protected in acting as custodian hereunder upon any
          instructions, advice, notice, request, consent, certificate or other
          instrument or paper appearing to it to be genuine and to have been
          properly executed and shall be entitled to receive upon request as
          conclusive proof of any fact or matter required to be ascertained from
          Fund hereunder a certificate signed by an officer or designated
          representative of Fund.

     F.   Custodian shall be under no duty or obligation to inquire into, and 
          shall not be liable for:

          1.  The validity of the issue of any securities purchased by or for
              Fund, the legality of the purchase of any securities or foreign
              currency positions or evidence of ownership required by Fund to be
              received by

                                       24
<PAGE>
 
              Custodian, or the propriety of the decision to purchase or amount
              paid therefor;

          2.  The legality of the sale of any securities or foreign currency
              positions by or for Fund, or the propriety of the amount for which
              the same are sold;

          3.  The legality of the issue or sale of any Fund Shares, or the 
              sufficiency of the amount to be received therefor;

          4.  The legality of the repurchase or redemption of any Fund Shares, 
              or the propriety of the amount to be paid therefor; or

          5.  The legality of the declaration of any dividend by Fund, or the
              legality of the issue of any Fund Shares in payment of any stock 
              dividend.

     G.   Custodian shall not be liable for, or considered to be Custodian of, 
          any money represented by any check, draft, wire transfer,
          clearinghouse funds, uncollected funds, or instrument for the payment
          of money to be received by it on behalf of Fund until Custodian
          actually receives such money; provided, however, that it shall advise
          Fund promptly if it fails to receive any such money in the ordinary
          course of business and shall cooperate with Fund toward the end that
          such money shall be received.

     H.   Except as provided in Section 3-S., Custodian shall not be responsible
          for loss occasioned by the acts, neglects, defaults or insolvency of
          any broker, bank, trust company, or any other person with whom
          Custodian may deal.

                                       25
<PAGE>
 
     I.   Custodian shall not be responsible or liable for the failure or delay
          in performance of its obligations under this Agreement, or those of
          any entity for which it is responsible hereunder, arising out of or
          caused, directly or indirectly, by circumstances beyond the affected
          entity's reasonable control, including, without limitation: any
          interruption, loss or malfunction of any utility, transportation,
          computer (hardware or software) or communication service; inability to
          obtain labor, material, equipment or transportation, or a delay in
          mails; governmental or exchange action, statute, ordinance, rulings,
          regulations or direction; war, strike, riot, emergency, civil
          disturbance, terrorism, vandalism, explosions, labor disputes,
          freezes, floods, fires, tornadoes, acts of God or public enemy,
          revolutions, or insurrections.

     J.   IN NO EVENT AND UNDER NO CIRCUMSTANCES SHALL EITHER PARTY TO THIS
          AGREEMENT BE LIABLE TO ANYONE, INCLUDING, WITHOUT LIMITATION TO THE
          OTHER PARTY, FOR CONSEQUENTIAL, SPECIAL OR PUNITIVE DAMAGES FOR ANY
          ACT OR FAILURE TO ACT UNDER ANY PROVISION OF THIS AGREEMENT EVEN IF
          ADVISED OF THIS POSSIBILITY THEREOF.

6.   COMPENSATION.  In consideration for its services hereunder, Fund will pay 
     to Custodian such compensation as shall be set forth in a separate fee
     schedule to be agreed to by Fund and Custodian from time to time. A copy of
     the initial fee schedule is attached hereto and incorporated herein by
     reference. Custodian shall also be

                                       26
<PAGE>
 
     entitled to receive, and Fund agrees to pay to Custodian, on demand,
     reimbursement for Custodian's cash disbursements and reasonable out-of-
     pocket costs and expenses, including attorney's fees, incurred by Custodian
     in connection with the performance of services hereunder. Custodian may
     charge such compensation against monies held by it for the account of Fund.
     Custodian will also be entitled to charge against any monies held by it for
     the account of Fund the amount of any loss damage, liability, advance,
     overdraft or expense for which it shall be entitled to reimbursement from
     Fund, including but not limited to fees and expenses due to Custodian for
     other services provided to the Fund by Custodian. Custodian will be
     entitled to reimbursement by the Fund for the losses, damages, liabilities,
     advances, overdrafts and expenses of subcustodians only to the extent that
     (i) Custodian would have been entitled to reimbursement hereunder if it had
     incurred the same itself directly, and (ii) Custodian is obligated to
     reimburse the subcustodian therefor.

7.   TERM AND TERMINATION.  The initial term of this Agreement shall be for a 
     period of one (1) year. Thereafter, either party to this Agreement may
     terminate the same by notice in writing, delivered or mailed, postage
     prepaid, to the other party hereto and received not less than sixty (60)
     days prior to the date upon which such termination will take effect. Upon
     termination of this Agreement, Fund will pay Custodian its fees and
     compensation due hereunder and its reimbursable disbursements, costs and
     expenses paid or incurred to such date and Fund shall designate a successor
     custodian by notice in writing to Custodian by the termination date. In the
     event no written order designating a successor custodian has been

                                       27
<PAGE>
 
     delivered to Custodian on or before the date when such termination becomes
     effective, then Custodian may, at its option, deliver the securities, funds
     and properties of Fund to a bank or trust company at the selection of
     Custodian, and meeting the qualifications for custodian set forth in the
     1940 Act and having not less than Two Million Dollars ($2,000,000)
     aggregate capital, surplus and undivided profits, as shown by its last
     published report, or apply to a court of competent jurisdiction for the
     appointment of a successor custodian or other proper relief, or take any
     other lawful action under the circumstances; provided, however, that Fund
     shall reimburse Custodian for its costs and expenses, including reasonable
     attorney's fees, incurred in connection therewith. Custodian will, upon
     termination of this Agreement and payment of all sums due to Custodian from
     Fund hereunder or otherwise, deliver to the successor custodian so
     specified or appointed, or as specified by the court, at Custodian's
     office, all securities then held by Custodian hereunder, duly endorsed and
     in form for transfer, and all funds and other properties of Fund deposited
     with or held by Custodian hereunder, and Custodian will co-operate in
     effecting changes in book-entries at all Depositories. Upon delivery to a
     successor custodian or as specified by the court, Custodian will have no
     further obligations or liabilities under this Agreement. Thereafter such
     successor will be the successor custodian under this Agreement and will be
     entitled to reasonable compensation for its services. In the event that
     securities, funds and other properties remain in the possession of the
     Custodian after the date of termination hereof owing to failure of the Fund
     to appoint a successor custodian, the Custodian shall be entitled to

                                       28
<PAGE>
 
     compensation as provided in the then-current fee schedule hereunder for its
     services during such period as the Custodian retains possession of such
     securities, funds and other properties, and the provisions of this
     Agreement relating to the duties and obligations of the Custodian shall
     remain in full force and effect.

8.   NOTICES.  Notices, requests, instructions and other writings addressed to 
     Fund at 307 North Michigan Avenue, Suite 500, Chicago, Illinois 60601 or at
     such other address as Fund may have designated to Custodian in writing,
     will be deemed to have been properly given to Fund hereunder; and notices,
     requests, instructions and other writings addressed to Custodian at its
     offices at 127 West 10th Street, Kansas City, Missouri 64105, Attention:
     Custody Department, or to such other address as it may have designated to
     Fund in writing, will be deemed to have been properly given to Custodian
     hereunder.

9.   MULTIPLE PORTFOLIOS.  If Fund is comprised of more than one Portfolio:

     A.   Each Portfolio shall be regarded for all purposes hereunder as a
          separate party apart from each other Portfolio. Unless the context
          otherwise requires, with respect to every transaction covered by this
          Agreement, every reference herein to the Fund shall be deemed to
          relate solely to the particular Portfolio to which such transaction
          relates. Under no circumstances shall the rights, obligations or
          remedies with respect to a particular Portfolio constitute a right,
          obligation or remedy applicable to any other Portfolio. The use of
          this single document to memorialize the separate agreement of each
          Portfolio is

                                       29
<PAGE>
 
          understood to be for clerical convenience only and shall not
          constitute any basis for joining the Portfolios for any reason.

     B.   Additional Portfolios may be added to this Agreement, provided that 
          Custodian consents to such addition. Rates or charges for each
          additional Portfolio shall be as agreed upon by Custodian and Fund in
          writing.

10.  LIMITATION OF LIABILITY.  Notice is hereby given that a copy of the Fund's
     Trust Agreement and all amendments thereto is on file with the Secretary of
     State of the state of its organization; that this Agreement has been
     executed on behalf of the Fund by the undersigned duly authorized
     representative of Fund in his/her capacity as such and not individually;
     and that the obligations of this Agreement shall only be binding upon the
     assets and property of Fund and shall not be binding upon any trustee,
     officer or shareholder of Fund individually.

11.  MISCELLANEOUS.

          principles thereof.

          inure to the benefit of and be enforceable by the parties hereto and
          their respective successors and permitted assigns.

          manner except by a written agreement properly authorized and executed
          by each party hereto.

     E.   The failure of either party to insist upon the performance of any
          terms or conditions of this Agreement or to enforce any rights
          resulting from any breach of any of the terms or conditions of this
          Agreement, including the payment of damages, shall not be construed as
          a continuing or permanent waiver of any such terms, conditions, rights
          or privileges, but the same shall continue and remain in full force
          and effect as if no such forbearance or waiver had occurred. No
          waiver, release or discharge of any party's rights hereunder shall be
          effective unless contained in a written instrument signed by the party
          sought to be charged.

     F.   The captions in the Agreement are included for convenience of
          reference only, and in no way define or delimit any of the provisions
          hereof or otherwise affect their construction or effect.

     G.   This Agreement 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.

     H.   If any part, term or provision of this Agreement is determined by the 
          courts or any regulatory authority to be illegal, in conflict with any
          law or otherwise invalid, the remaining portion or portions shall be
          considered severable and not be affected, and the rights and
          obligations of the parties shall be construed

                                       31
<PAGE>
 
          and enforced as if the Agreement did not contain the particular part,
          term or provision held to be illegal or invalid.

     I.   This Agreement may not be assigned by either party hereto without the 
          prior written consent of the other party.

     J.   Neither the execution nor performance of this Agreement shall be 
          deemed to create a partnership or joint venture by and between 
          Custodian and Fund.

     K.   Except as specifically provided herein, this Agreement does not in any
          way affect any other agreements entered into among the parties hereto
          and any actions taken or omitted by either party hereunder shall not
          affect any rights or obligations of the other party hereunder.

     IN WITNESS WHEREOF, the parties have caused this Agreement to be executed
by their respective duly authorized officers.

     E.   IFTC shall use reasonable efforts to provide, reasonably promptly 
          under the circumstances, services with respect to any new, additional
          Fund functions or features or any changes or improvements to existing
          Fund functions or features provided for in Fund's instructions or
          prospectus, as amended from time to time, provided (i) IFTC is
          advised, a reasonable time in advance, by the Fund of any changes
          therein and (ii) the TA2000/TM/ System and mode of operations utilized
          by IFTC as then constituted

                                       4
<PAGE>
 
          supports such additional functions and features. If any addition to,
          improvement of or change in the Fund features and functions currently
          provided or the operations as requested by the Fund requires an
          enhancement or modification to the TA2000/TM/ System or to operations
          as then conducted by IFTC, IFTC shall not be liable therefor until
          such modification or enhancement is installed on the TA2000/TM/ System
          or new mode of operation is instituted. If any new or additional Fund
          function or feature, change or improvement to existing Fund functions
          or features, or new service or change in mode of operation required by
          the Fund increases IFTC's cost of performing the services required
          hereunder at the then current level of service, IFTC shall advise the
          Fund of the amount of such increase and if the Fund elects to utilize
          such function, feature or changed method of service, IFTC shall be
          entitled to increase its fees by the amount of the increase in costs.

     F.   To the extent that the Fund requests IFTC to perform any of the 
          foregoing services in a manner not consistent with utilization of
          TA2000/TM/ or IFTC's usual processing procedures or to the extent the
          Fund requests performance of additional services not enumerated above,
          IFTC and the Fund shall mutually agree as to the services to be
          accomplished, the manner of accomplishment and the compensation to
          which IFTC shall be entitled with respect thereto.

5.   Compensation and Expenses.

     A.   In consideration for its services hereunder as Transfer Agent and 
          Paying Agent, Fund will pay to IFTC such compensation as shall be set
          forth in a separate fee schedule to be agreed to by Fund and IFTC from
          time to time. A copy of the initial fee schedule is attached hereto
          and incorporated herein by reference. IFTC may charge against any
          monies held by it for the Fund, the amount of any compensation and/or
          loss, damage, liability, advance, overdraft or expense for which it
          shall be entitled to payment or reimbursement from the Fund.

     B.   The Fund also agrees promptly to reimburse IFTC for all reasonable 
          out-of-pocket expenses or disbursements incurred by IFTC in connection
          with the performance of services under this Agreement including, but
          not limited to, expenses for postage,

                                       5
<PAGE>
 
          express delivery services, freight charges, envelopes, checks, drafts,
          forms (continuous or otherwise), specially requested reports and
          statements, telephone calls, telegraphs, stationary supplies, counsel
          fees, outside printing and mailing firms (including Output Technology,
          Inc. and Support Resources, Inc.), magnetic tapes, reels or cartridges
          (if sent to a Fund or to third party at the Fund's request) and
          magnetic tape handling charges, off-site record storage, media for
          storage of records (e.g., microfilm, microfiche, optical platters,
          computer tapes), computer equipment installed at the Fund's request at
          the Fund's or a third party's premises, telecommunications equipment,
          telephone/telecommunication lines between Fund and its agents, on one
          hand, and IFTC on the other, proxy soliciting, processing and/or
          tabulating costs, second-site backup computer facility, transmission
          of statement data for remote printing or processing, and NSCC
          transaction fees to the extent any of the foregoing are paid by IFTC.
          The Fund agrees to pay postage expenses at least one day in advance if
          so requested. In addition, any other expenses incurred by IFTC at the
          request or with the consent of the Fund will be promptly reimbursed by
          the Fund.

     C.   Amounts due hereunder shall be due and paid by the Fund on or before 
          the thirtieth (30th) day after the date of the statement therefor (the
          "Due Date"). The Fund is aware that its failure to pay all amounts in
          a timely fashion so that they will be received by IFTC on or before
          the Due Date will give rise to costs to IFTC not contemplated by this
          Agreement, including but not limited to carrying, processing and
          accounting charges. Accordingly, subject to Section 5.D. hereof, in
          the event that any amounts due hereunder are not received by IFTC by
          the Due Date, the Fund shall pay a late charge equal to the rate set
          forth in the Fee Schedule. The parties hereby agree that such late
          charge represents a fair and reasonable computation of the costs
          incurred by reason of late payment or payment of amounts not properly
          due. Acceptance of such late charge shall in no event constitute a
          waiver of the Fund's or IFTC's default or prevent the non-defaulting
          party from exercising any other rights and remedies available to it.

                                       6
<PAGE>
 
     D.   In the event that any charges are disputed, the Fund shall, on or 
          before the Due Date, pay all undisputed amounts due hereunder and
          notify IFTC in writing of any disputed charges for out-of-pocket
          expenses which it is disputing in good faith. Payment for such
          disputed charges shall be due on or before the close of the fifth
          (5th) business day after the day on which IFTC provides to the Fund
          documentation which an objective observer would agree reasonably
          supports the disputed charges (the "Revised Due Date"). Late charges
          shall not begin to accrue as to charges disputed in good faith until
          the first day after the Revised Due Date.

6.   Operation of IFTC System.

     In connection with the performance of its services under this Agreement, 
     IFTC is responsible for such items as:

     A.   That entries in IFTC's records and in the Fund's records on the

          and other information received by IFTC from broker-dealers,
          shareholders, the Fund, the Fund's principal underwriter or Fund's
          investment adviser;

     B.   That shareholder lists, shareholder account verifications, 
          confirmations and other shareholder account information to be produced
          from its records or data be available and accurately reflect the data
          in the Fund's records on the TA2000/TM/ System;

     C.   The accurate and timely issuance of dividend and distribution checks 
          in accordance with instructions received from the Fund and the data

     D.   That redemption transactions and payments be effected timely and 
          accurately in accordance with redemption instructions received by IFTC

     F.   Notwithstanding anything herein to the contrary, with respect to "as 
          of" adjustments, IFTC will not assume one hundred percent (100%)
          responsibility for losses resulting from "as of's" due to clerical
          errors or misinterpretations of shareholder instructions, but IFTC
          will discuss with the Fund IFTC's accepting liability for an "as of"
          on a case-by-case basis and may accept financial responsibility for a
          particular situation resulting in a financial loss to the Fund where
          IFTC in its discretion deems that to be appropriate;

     G.   The requiring of proper forms of instructions, signatures and 
          signature guarantees and any necessary documents supporting the
          opening of shareholder accounts transfers, redemptions and other
          shareholder account transactions, all in conformance with IFTC's
          present procedures as set forth in its Legal Manual, Third Party Check
          Procedures, Checkwriting Draft Procedures, and Signature Guarantee
          Procedures with such changes or deviations therefrom as may be from
          time to time required or approved by the Fund, its investment adviser
          or principal underwriter, or their or IFTC's counsel (the
          "Procedures") and the rejection of orders or instructions not in good
          order in accordance with the applicable prospectus or the Procedures;

     H.   The maintenance of customary records in connection with its agency, 
          and particularly those records required to be maintained pursuant to

          main operation.

          good faith in performing its duties under this Agreement. IFTC shall
          be presumed to have used reasonable care, due diligence and acted in

<PAGE>
 
          be amended from time to time with approval of IFTC's counsel or the
          Fund. IFTC shall not be responsible for, and the Fund shall indemnify
          and hold IFTC harmless from and against, any and all losses, damages,
          costs, charges, counsel fees, payments, expenses and liability which
          may be asserted against IFTC, incurred by IFTC or for which IFTC may
          be held to be liable, arising out of or attributable to:

          (1)   All actions of IFTC required to be taken by IFTC pursuant to 
                this Agreement, provided that IFTC has acted in good faith and
                with due diligence and reasonable care;

          (2)   The Fund's refusal or failure to comply with the terms of this

          (3)   The good faith reliance on, or the carrying out of, any written
                or recorded oral instructions or requests of persons designated

                instructions on its behalf or representatives of the Fund's
                investment adviser, sponsor or principal underwriter or IFTC's
                good faith reliance on, or use of, information, data, records
                and documents received from, or which have been prepared and/or
                maintained by the Fund, its investment adviser, its sponsor or
                its principal underwriter;

                respect to the offer or sale of such shares (unless such
                violation results from IFTC's failure to comply with written
                instructions of the Fund or of any officer of the Fund that no
                offers or sales to residents of such state be input into the

                access the TA2000/TM/ System (the "TA2000/TM/ Facilities"), and
                control procedures relating thereto in the verification of
                output and in the remote input of data;

          (7)   Errors, inaccuracies, out-of-balance conditions and omissions 
                in, or errors, inaccuracies or omissions of IFTC arising out of
                or resulting from such errors, inaccuracies, out-of-balance
                conditions and omissions in, the Fund's records, shareholder and
                other records, delivered to IFTC hereunder by the Fund or its
                prior agent(s); and

          (8)   Actions or omissions to act by the Fund or agents designated by
                the Fund with respect to duties assumed thereby as provided for 
                in Section 20 hereof.

     B.   Except where IFTC is entitled to indemnification under Section 7.A. 
          hereof, IFTC shall indemnify and hold the Fund harmless from and
          against any and all losses, damages, costs, charges, counsel fees,
          payments, expenses and liability arising out of IFTC's failure to
          comply with the terms of this Agreement or arising out of or
          attributable to IFTC's negligence or willful misconduct or breach of
          any representation or warranty of IFTC hereunder. Notwithstanding
          anything herein to the contrary, IFTC will not indemnify or hold the
          Fund harmless as to losses, damages, costs, charges, counsel fees,
          payments, expenses and liability arising out of or resulting from "as
          of's" due to clerical errors or misinterpretations of shareholder
          instructions, but IFTC will discuss with the Fund on a case-by-case
          basis the possibility of IFTC's accepting liability for a particular
          "as of" and may accept financial responsibility for a particular
          situation resulting in a financial loss to the Fund where IFTC in its
          discretion deems that to be appropriate.

     C.   EXCEPT FOR VIOLATIONS OF SECTION 22, IN NO EVENT AND UNDER NO 
          CIRCUMSTANCES SHALL EITHER PARTY TO THIS AGREEMENT BE LIABLE TO
          ANYONE, INCLUDING, WITHOUT LIMITATION TO THE OTHER PARTY, FOR
          CONSEQUENTIAL OR PUNITIVE DAMAGES FOR

                                       10
<PAGE>
 
          ANY ACT OR FAILURE TO ACT UNDER ANY PROVISION OF THIS AGREEMENT EVEN
          IF ADVISED OF THE POSSIBILITY THEREOF.

8.   Certain Covenants of IFTC and Fund.

     A.   All requisite steps will be taken by Fund from time to time when and 
          as necessary to register the Fund's shares for sale in all states in
          which Fund's shares shall at the time be offered for sale and require
          registration. If at any time Fund will receive notice of any stop
          order or other proceeding in any such state affecting such
          registration or the sale of Fund's shares, or of any stop order or
          other proceeding under the federal securities laws affecting the sale
          of Fund's shares, Fund will give prompt notice thereof to IFTC.

     B.   IFTC hereby agrees to perform such transfer agency functions as are 
          set forth in section 4.D. above and establish and maintain facilities
          and procedures for safekeeping of stock certificates, check forms, and
          facsimile signature imprinting devices, if any; and for the
          preparation or use, and for keeping account of, such certificates,
          forms and devices, and to carry such insurance as it considers
          adequate and reasonably available.

     C.   To the extent required by Section 31 of the Investment Company Act of
          1940 (the "1940 Act") as amended and Rules thereunder, IFTC agrees
          that all records maintained by IFTC relating to the services to be
          performed by IFTC under this Agreement are the property of Fund and
          will be preserved for the period required by the 1940 Act or such
          longer period as the Fund may require in writing and will be
          surrendered promptly to Fund on request.

     D.   IFTC will permit Fund and its authorized accountants, upon the 
          execution of IFTC's Confidentiality Agreement, to make periodic
          inspections and audits of its operations as such would involve the
          Fund at reasonable times during business hours.

9.   Recapitalization or Readjustment.

     In case of any recapitalization, readjustment or other change in the
     capital structure of Fund requiring a change in the form of stock
     certificates, IFTC will issue or register certificates in

                                       11
<PAGE>
 
     the new form in exchange for, or in transfer of, the outstanding
     certificates in the old form, upon receiving:

     A.   Written instructions from an officer of Fund; and

     B.   Specimens and a sufficient working supply of the new certificates in 
          the form approved by the Board of Directors of Fund, with a
          certificate of the Secretary of Fund as to such approval.

10.  Stock Certificates.

     Fund will furnish IFTC with a sufficient supply of blank stock certificates
     and from time to time will renew such supply upon the request of IFTC. Such
     certificates will be signed manually or by facsimile signatures of the
     officers of Fund authorized by law and by bylaws to sign stock
     certificates, and if required, will bear the corporate seal or facsimile
     thereof.

11.  Death, Resignation or Removal of Signing Officer.

     Fund will file promptly with IFTC written notice of any change in the
     officers authorized to sign stock certificates, written instructions or
     requests, together with two signature cards bearing the specimen signature
     of each newly authorized officer. In case any officer of Fund who will have
     signed manually or whose facsimile signature will have been affixed to
     blank stock certificates will die, resign, or be removed prior to the
     issuance of such certificates, IFTC may issue or register such stock
     certificates as the stock certificates of Fund notwithstanding such death,
     resignation, or removal, until specifically directed to the contrary by
     Fund in writing. In the absence of such direction, Fund will file promptly
     with IFTC such approval, adoption, or ratification as may be required by
     law.

12.  Future Amendments of Charter and Bylaws.

     Fund will promptly file with IFTC copies of all material amendments to its
     Articles of Incorporation or bylaws made after the date of this Agreement.

13.  Instructions, Opinion of Counsel and Signatures.

     At any time IFTC may apply to any person authorized by the Fund to give
     instructions to IFTC, or, at the expense of the Fund, may consult with
     legal counsel for Fund or, at the expense of the Fund and with the approval
     of a Fund officer, may consult with its own legal counsel with respect to
     any matter arising in connection with the agency and it will not be

                                       12
<PAGE>
 
     liable for any action taken or omitted by it in good faith in reliance upon
     such instructions or upon the opinion of such counsel. IFTC will be
     protected in acting upon any paper or document reasonably believed by it to
     be genuine and to have been signed by the proper person or persons and will
     not be held to have notice of any change of authority of any person until
     receipt of written notice thereof from Fund. It will also be protected in
     recognizing stock certificates which it reasonably believes to bear the
     proper manual or facsimile signatures of the officers of Fund, and the
     proper countersignature of any former transfer agent or registrar, or of a
     co-transfer agent or co-registrar.

14.  Papers Subject to Approval of Counsel.

     The acceptance by IFTC of its appointment as transfer agent, agent and
     depository and all documents filed in connection with such appointment and
     thereafter in connection with the agencies, will be subject to the approval
     of legal counsel for IFTC (which approval will be not unreasonably
     withheld).

15.  Certification of Documents.

     The required copy of the articles of incorporation of Fund and copies of
     all amendments thereto will be certified by the Secretary of State (or
     other appropriate official) of the state of incorporation, and if such
     articles of incorporation and amendments are required by law to be also
     filed with a county, city or other officer of official body, a certificate
     of such filing will appear on the certified copy submitted to IFTC. A copy
     of the order or consent of each governmental or regulatory authority
     required by law to the issuance of the stock will be certified by the
     Secretary or Clerk of such governmental or regulatory authority, under
     proper seal of such authority. The copy of the bylaws and copies of all
     amendments thereto, and copies of resolutions of the Board of Directors of
     Fund, will be certified by the secretary or an assistant secretary of Fund
     under the Fund's seal.

16.  Records.

     IFTC will maintain customary records in connection with its agency, and
     particularly will maintain those records required to be maintained pursuant
     to subparagraph (2) (iv) of paragraph (b) of Rule 31a-1 under the
     Investment Company Act of 1940, if any.

                                       13
<PAGE>
 
17.  Disposition of Books, Records and Canceled Certificates.

     IFTC may send periodically to Fund, or to where designated by the Fund, all
     books, documents, and all records no longer deemed needed for current
     purposes and stock certificates which have been canceled in transfer or in
     exchange, upon the understanding that such books, documents, records, and
     stock certificates will be maintained by the Fund under and in accordance
     with the requirements of Section 17Ad-7 adopted under the Securities
     Exchange Act of 1934. Such materials will not be destroyed by Fund without
     the consent of IFTC (which consent will not be unreasonably withheld), but
     will be safely stored for possible future reference.

18.  Provisions Relating to IFTC as Transfer Agent.

     A.   IFTC will make original issues of stock certificates upon written 
          request of an officer of Fund and upon being furnished with a
          certified copy of a resolution of the Board of Directors authorizing
          such original issue, an opinion of counsel and other documents as
          outlined in paragraph 1. of this Agreement, a sufficient supply of
          blank stock certificates and necessary funds for the payment of any
          original issue tax.

     B.   Before making any original issue of certificates Fund will furnish 
          IFTC with sufficient funds to pay all required taxes on the original
          issue of the stock, if any. Fund will furnish IFTC such evidence as
          may be required by IFTC to show the actual value of the stock. Fund
          shall be responsible for ascertaining if any taxes are required to be
          paid and, if so, for paying such taxes.

     C.   Shares of stock will be transferred and new certificates issued in 
          transfer, or shares of stock accepted for redemption and funds
          remitted therefor, upon surrender of the old certificates in form
          deemed by IFTC properly endorsed for transfer or redemption
          accompanied by such documents as IFTC may deem necessary to evidence
          that authority of the person making the transfer or redemption, and
          bearing satisfactory evidence of the payment of any applicable stock
          transfer taxes. IFTC reserves the right to refuse to transfer or
          redeem shares until it is satisfied that the endorsement or signature
          on the certificate or any other document is valid and genuine, and for
          that purpose it may require a guaranty of signature by an eligible
          guarantor institution, as

                                       14
<PAGE>
 
          that term is defined in Rule 17Ad-15, adopted under the Securities
          Exchange Act of 1934, and as implemented by IFTC's Signature Guarantee
          Procedures. IFTC also reserves the right to refuse to transfer or
          redeem shares until it is satisfied that the requested transfer or
          redemption is legally authorized, and it will incur no liability for
          the refusal in good faith to make transfers or redemptions which, in
          its judgment, are improper or unauthorized. IFTC may, in effecting
          transfers or redemptions, rely upon Simplification Acts or other
          statutes which protect it and Fund in not requiring complete fiduciary
          documentation. In cases in which IFTC is not directed or otherwise
          required to maintain the consolidated records of shareholder's
          accounts, IFTC will not be liable for any loss which may arise by
          reason of not having such records.

     D.   When mail is used for delivery of stock certificates, IFTC will 
          forward stock certificates in "nonnegotiable" form by first class or
          registered mail and stock certificates in "negotiable" form by
          registered mail, all such mail deliveries to be covered while in
          transit to the addressee by insurance arranged for by IFTC.

     E.   IFTC will issue and mail subscription warrants, certificates 
          representing stock dividends, exchanges or split ups, or act as
          conversion agent upon receiving written instructions from any officer
          of Fund and such other documents as IFTC deems necessary.

     F.   IFTC will issue, transfer, and split up certificates and will issue 
          certificates of stock representing full shares upon surrender of scrip
          certificates aggregating one full share or more when presented to IFTC
          for that purpose upon receiving written instructions from an officer
          of Fund and such other documents as IFTC may deem necessary.

     G.   IFTC may issue new certificates in place of certificates represented 
          to have been lost, destroyed, stolen or otherwise wrongfully taken
          upon receiving instructions from Fund and indemnity satisfactory to
          IFTC and Fund, and may issue new certificates in exchange for, and
          upon surrender of, mutilated certificates.

                                       15
<PAGE>
 
     H.   IFTC will supply a shareholder's list to Fund for its annual meeting 
          upon receiving a request from an officer of Fund.  It will also 
          supply lists at such other times as may be requested by an officer of
          Fund.

     I.   Upon receipt of written instructions of an officer of Fund, IFTC will
          address and mail notices to shareholders.

     J.   In case of any request or demand for the inspection of the stock books
          of Fund or any other books in the possession of IFTC, IFTC will
          endeavor to notify Fund and to secure instructions as to permitting or
          refusing such inspection. IFTC reserves the right, however, to exhibit
          the stock books or other books to any person in case it is advised by
          its counsel that it may be held responsible for the failure to exhibit
          the stock books or other books to such person.

19.  Provisions Relating to Paying Agency.

     A.   IFTC will, at the expense of Fund, provide a special form of check 
          containing the imprint of any device or other matter desired by Fund.
          Said checks must, however, be of a form and size convenient for use by
          IFTC.

     B.   If Fund desires to include additional printed matter, financial 
          statements, etc., with the dividend checks, the same will be furnished
          to IFTC within a reasonable time prior to the date of mailing of the 
          dividend checks, at the expense of Fund.

     C.   If Fund desires its distributions mailed in any special form of 
          envelopes, sufficient supply of the same will be furnished to IFTC but
          the size and form of said envelopes will be subject to the approval of
          IFTC. If stamped envelopes are used, they must be furnished by Fund;
          or if postage stamps are to be affixed to the envelopes, the stamps or
          the cash necessary for such stamps must be furnished by Fund.

     D.   IFTC will open and maintain in its banking department one or more 
          non-interest bearing deposit accounts as agent for Fund, into which
          the moneys received for the account of the Fund for payment of
          dividends, distributions, redemptions or other disbursements provided
          for hereunder will be deposited, and against which checks will be
          drawn. If IFTC shall in its sole discretion advance funds to or for
          the account of Fund which results in an overdraft in any such account
          because the monies held

                                       16
<PAGE>
 
          therein by IFTC on behalf of Fund are insufficient to pay the total
          amount payable from such account for any reason, the amount of the
          overdraft shall be payable by Fund to IFTC upon demand together with
          the overdraft charge set forth in the then-current fee schedule from
          the date advanced until the date final payment is received.

     E.   IFTC is authorized and directed to stop payment of checks theretofore 
          issued hereunder, but not presented for payment, when the payees
          thereof allege either that they have not received the checks or that
          such checks have been mislaid, lost, stolen, destroyed or through no
          fault of theirs, are otherwise beyond their control, and cannot be
          produced by them for presentation and collection, and, to issue and
          deliver duplicate checks in replacement thereof.

20.  Assumption of Duties By the Fund or Agents Designated By the Fund.

     A.   The Fund, its designated agents other than IFTC or any subcontractor
          employed by the Fund or IFTC at the direction or request of the Fund
          may assume certain duties and responsibilities of IFTC or those
          services of Transfer Agent and Paying Agent as those terms are
          referred to in Section 4.D. of this Agreement including but not
          limited to: answering and responding to telephone inquiries from
          shareholders and broker-dealers; accepting shareholder and broker
          instructions (both oral and written) and transmitting orders or
          directions based on such instructions to IFTC; preparing and mailing
          confirmations; obtaining certified TIN numbers; establishing
          shareholder accounts on the TA2000/TM/ System, classifying the status
          of shareholders and shareholder accounts under applicable tax law and
          assigning social codes and Taxpayer Identification Number codes
          thereto; and disbursing monies of the Fund. Any assumption of duties
          and responsibilities and any amendments thereto must be embodied in
          writing and signed by both parties.

     B.   To the extent the Fund or its agent or affiliate assumes such duties 
          and responsibilities, IFTC shall be relieved from all responsibility
          and liability therefor and is hereby indemnified and held harmless
          against any liability therefrom and in the same manner and degree as
          provided for in Section 7 hereof.

                                       17
<PAGE>
 
21.  Termination of Agreement.

     A.   This Agreement shall remain in full force and effect for a period of 
          two (2) years, the initial term of this Agreement, and thereafter
          shall automatically extend for additional, successive twelve (12)
          month terms upon the expiration of any term hereof, unless terminated
          at any time after the initial term by either party by delivery of six
          (6) months prior written notice of termination to the other party.

     B.   Each party, in addition to any other rights and remedies, shall have 
          the right to terminate this Agreement forthwith upon the occurrence 
          at any time of any of the following events with respect to the other 
          party:

          (1)   Any interruption or cessation of operations by the other party 
                or its assigns which materially interferes with the business
                operation of the first party;

          (2)   The bankruptcy of the other party or its assigns or the 
                appointment of a receiver for the other party or its assigns;

          (3)   Any merger, consolidation or sale of substantially all the 
                assets of the other party or its assigns; or

          (4)   Failure by the other party or its assigns to perform its duties
                in accordance with the Agreement, which failure materially
                adversely affects the business operations of the first party and
                which failure continues for thirty (30) days after receipt of
                written notice from the first party.

     C.   In the event of termination, Fund will promptly pay IFTC all amounts 
          due to IFTC hereunder.

     D.   In the event of termination, IFTC will use its best efforts to 
          transfer the books and records of the Fund to the designated successor
          transfer agent and to provide other information relating to its
          service provided hereunder for reasonable compensation therefore.

22.  Confidentiality.

     A.   IFTC agrees that, except as provided in the last sentence of Section 
          19.J hereof, or as otherwise required by law, IFTC will keep
          confidential all records of and information in its possession relating
          to Fund or its shareholders or shareholder

                                       18
<PAGE>
 
          accounts and will not disclose the same to any person except at the
          request or with the consent of Fund.

     B.   Fund agrees to keep confidential all financial statements and other 
          financial records and all manuals, systems and other technical
          information and data, not publicly disclosed, relating to IFTC's
          operations and programs furnished to it by IFTC pursuant to this
          Agreement and will not disclose the same to any person except at the
          request or with the consent of IFTC.

     C.   The Fund acknowledges that IFTC and DST Systems, Inc. (DST) have 
          proprietary rights in and to the TA2000/TM/ System, including, without
          limitation any changes or modifications thereto and any other IFTC or
          DST programs, code, techniques, know-how, data bases, supporting
          documentation, data formats, or procedures ("collectively IFTC
          Protected Information") which the Fund's access to the TA2000/TM/
          System or TA2000/TM/ Facilities may permit the Fund or its employees
          or agents to become aware of or to access and that the IFTC Protected
          Information constitutes confidential material and trade secrets of
          IFTC. The Fund agrees to maintain the confidentiality of the IFTC
          Protected Information. The Fund acknowledges that any unauthorized
          use, misuse, disclosure or taking of IFTC Protected Information which
          is confidential as provided by law, or which is a trade secret,
          residing or existing internal or external to a computer, computer
          system, or computer network, or the knowing and unauthorized accessing
          or causing to be accessed of any computer, computer system, or
          computer network, may be subject to civil liabilities and criminal
          penalties under applicable law. The Fund will advise all of its
          employees and agents who have access to any IFTC Protected Information
          or to any computer equipment capable of accessing IFTC or DST hardware
          or software of the foregoing. DST is intended to be, and shall be, a
          third party beneficiary of the Fund's obligations and undertakings
          contained in this Section.

23.  Changes and Modifications.

     A.   During the term of this Agreement IFTC will use on behalf of the Fund
          without additional cost all modifications, enhancements, or changes 
          which DST or IFTC may

                                       19

          clients are charged separately for such modifications, enhancements or
          changes, including, without limitation, substantial system revisions
          or modifications necessitated by changes in existing laws, rules or
          regulations. The Fund agrees to pay IFTC promptly for modifications
          and improvements which are charged for separately at the rate provided
          for in DST's or IFTC's standard pricing schedule which shall be
          identical for substantially all clients, if a standard pricing
          schedule shall exist. If there is no standard pricing schedule, the
          parties shall mutually agree upon the rates to be charged.

     B.   IFTC shall have the right, at any time and from time to time, to alter
          and modify any systems, programs, procedures or facilities used or
          employed in performing its duties and obligations hereunder; provided
          that the Fund will be notified as promptly as possible prior to
          implementation of such alterations and modifications and that no such
          alteration or modification or deletion shall materially adversely
          change or affect the operations and procedures of the Fund in using or
          employing the TA2000/TM/ System or the TA2000/TM/ Facilities hereunder
          or the reports to be generated by such system and facilities
          hereunder, unless the Fund is given thirty (30) days prior notice to
          allow the Fund to change its procedures and IFTC provides the Fund
          with revised operating procedures and controls.

     C.   All enhancements, improvements, changes, modifications or new features
          added to the TA2000/TM/ System or otherwise made available by IFTC for
          use in connection with the business of the Fund however developed or
          paid for shall be, and shall remain, the confidential and exclusive
          property of, and proprietary to, DST Systems, Inc. and IFTC.

24.  Subcontractors.

     The Fund acknowledges that IFTC intends to subcontract certain obligations
     hereunder to affiliated entities and consents to such subcontracting on
     condition that IFTC shall remain fully responsible and liable for the
     complete and proper performance of IFTC's obligations

                                       20
<PAGE>
 
     hereunder, that all acts and omissions of any such subcontractor hereunder
     shall for all purposes hereof be considered and deemed to be acts or
     omissions of IFTC and that the Fund shall be fully responsible and liable
     hereunder to IFTC as if no subcontract had occurred and such obligations
     had been performed by IFTC itself. Nothing herein shall impose any duty
     upon IFTC in connection with or make IFTC liable for the actions or
     omissions to act of unaffiliated third parties such as, by way of example
     and not limitation, courier or next day delivery services, shipping
     companies, the U.S. mails or telecommunication companies, provided that, if
     IFTC selected such company, IFTC shall have exercised due care in selecting
     the same.

25.  Force Majeure.

     IFTC shall not be responsible or liable for its failure or delay in
     performance of its obligations under this Agreement arising out of or
     caused, directly or indirectly, by circumstances beyond its reasonable
     control, including, without limitation: any interruption, loss or
     malfunction of any utility, transportation, computer (hardware or software)
     or communication service; inability to obtain labor, material, equipment or
     transportation, or a delay in mails; governmental or exchange action,
     statute, ordinance, rulings, regulations or direction; war, strike, riot,
     emergency, civil disturbance, terrorism, vandalism, explosions, labor
     disputes, freezes, floods, fires, tornados, acts of God or public enemy,
     revolutions, or insurrection; or any other cause, contingency, circumstance
     or delay not subject to IFTC's control which prevents or hinders IFTC's
     performance hereunder.

26.  Limitations on Liability.

     A.   If Fund is comprised of more than one Portfolio, each Portfolio shall 
          be regarded for all purposes hereunder as a separate party apart from
          each other Portfolio. Unless the context otherwise requires, with
          respect to every transaction covered by this Agreement, every
          reference herein to the Fund shall be deemed to relate solely to the
          particular Portfolio to which such transaction relates. Under no
          circumstances shall the rights, obligations or remedies with respect
          to a particular Portfolio constitute a right, obligation or remedy
          applicable to any other Portfolio. The use of this single document to
          memorialize the separate agreement of each Portfolio is understood to

                                       21
<PAGE>
 
          be for clerical convenience only and shall not constitute any basis
          for joining the Portfolios for any reason.

     B.   Notice is hereby given that a copy of Fund's Trust Agreement and all 
          amendments thereto is on file with the Secretary of State of the state
          of its organization; that this Agreement has been executed on behalf
          of Fund by the undersigned duly authorized representative of Fund in
          his/her capacity as such and not individually; and that the
          obligations of this Agreement shall only be binding upon the assets
          and property of Fund and shall not be binding upon any trustee,
          officer or shareholder of Fund individually.

27.  Miscellaneous.

     A.   This Agreement shall be construed according to, and the rights and
          liabilities of the parties hereto shall be governed by, the laws of
          the State of Missouri, without reference to the choice of law
          provisions thereof.

     B.   All terms and provisions of this Agreement shall be binding upon, 
          inure to the benefit of and be enforceable by the parties hereto and 
          their respective successors and permitted assigns.

     C.   The representations and warranties, the indemnification extended 
          hereunder, and the provisions of Sections 22 and 26 are intended to

          cancellation of this Agreement.

          manner except by a written agreement properly authorized and executed
          each party hereto.

     E.   The captions in the Agreement are included for convenience of 
          reference only, and in no way define or delimit any of the provisions 
          hereof or otherwise affect their construction or effect.

     F.   This Agreement 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.

     G.   If any part, term or provision of this Agreement is determined by the
          courts or any regulatory authority having jurisdiction over the issue
          to be illegal, in conflict with any

                                       22
<PAGE>
 
          law or otherwise invalid, the remaining portion or portions shall be
          considered severable and not be affected, and the rights and
          obligations of the parties shall be construed and enforced as if the
          Agreement did not contain the particular part, term or provision held
          to be illegal or invalid.

     H.   This Agreement may not be assigned by either party hereto without the
          prior written consent of the other party.

     I.   Neither the execution nor performance of this Agreement shall be 
          deemed to create a partnership or joint venture by and between Fund
          and IFTC. It is understood and agreed that all services performed
          hereunder by IFTC shall be as an independent contractor and not as an
          employee of the Fund. This Agreement is between IFTC and the Fund and,
          except with respect to DST Systems, Inc. under Section 22 C hereof,
          neither this Agreement nor the performance of services under it shall
          create any rights in any third parties. There are no third party
          beneficiaries hereto.

     J.   Except as specifically provided herein, this Agreement does not in any
          way affect any other agreements entered into among the parties hereto
          and any actions taken or omitted by any party hereunder shall not
          affect any rights or obligations of any other party hereunder.

          resulting from any breach of any of the terms or conditions of this
          Agreement, including the payment of damages, shall not be construed as
          a continuing or permanent waiver of any such terms, conditions, rights
          or privileges, but the same shall continue and remain in full force
          and effect as if no such forbearance or waiver had occurred.

     L.   This Agreement constitutes the entire agreement between the parties 
          hereto and supersedes any prior agreement, draft or agreement or
          proposal with respect to the subject matter hereof, whether oral or
          written, and this Agreement may not be modified except by written
          instrument executed by both parties.

     Re:  Exhibit 10, Form N-1A
          Ariel Growth Fund


Ladies and Gentlemen:

     As Secretary of, and counsel to, Ariel Growth Fund (the "Trust"), it is my
opinion, based upon an examination of the Trust's Declaration of Trust and By-
Laws and such other original or photostatic copies of Trust records,
certificates of public officials, documents, papers, statutes, and authorities
as I deemed necessary to form the basis of this opinion, that the securities
being registered by this Registration Statement of the Trust will, when sold, be
legally issued, fully paid and non-assessable.

     Consent is hereby given to file this opinion of counsel with the Securities
and Exchange Commission as an Exhibit to the Trust's Registration Statement.

                                              Sincerely,



                                              /s/Catherine S. Bardsley

                         REPORT OF INDEPENDENT AUDITORS

The Board of Trustees and Shareholders of
Ariel Mutual Funds:

We have audited the accompanying statement of assets and liabilities, including
the schedule of investments, of Ariel Growth Fund and Ariel Appreciation Fund,
comprising Ariel Investment Trust ("Ariel Mutual Funds"), as of September 30,
1995, the related statement of operations for the year then ended, the statement
of changes in net assets for each of the two years in the period then ended and
the financial highlights for each of the fiscal periods since 1986.  These
financial statements and financial highlights are the responsibility of the
Ariel Mutual Funds' management.  Our responsibility is to express an opinion on
these financial statements and financial highlights based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement.  An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements.  Our procedures included confirmation of investments owned as of
September 30, 1995, by correspondence with the custodian and brokers.  An audit
also includes assessing the accounting principles used and significant estimates
made by management, as well  as evaluating the overall financial statement
presentation.  We believe that our audits provide a reasonable basis for our
opinion.

In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of Ariel
Mutual Funds at September 30, 1995, the results of their operations for the year
then ended, the changes in their net assets for each of the two years in the
period then ended and the financial highlights for each of the fiscal periods
since 1986, in conformity with generally accepted accounting principles.

                        CONSENT OF INDEPENDENT AUDITORS

We consent to the reference to our firm under the captions "Financial

any person relating to the implementation of this Plan shall be in writing, and
such agreements shall be subject to termination, without penalty, pursuant to
the provisions of paragraph 2(c) of this Plan.

     (b) Nothing in this Plan shall operate or be construed to limit the extent
to which the Fund's Investment Advisor or any other person, other than the Fund,
at its expense apart from the

shares.

     2.  Effective Date and Term.

person at a meeting called for the purpose of voting on this Plan, and (ii) the
outstanding voting securities of the Fund.

     (b) This Plan shall remain in effect for one year from its adoption date

Qualified Trustees, cast in person at a meeting called for the purpose of voting
on the Plan.

     (c) This Plan may be terminated at any time by a majority vote of the

Fund, and of the Qualified Trustees, cast in person at a meeting called for the
purpose of voting thereon.
