                         State Farm Interim Fund, Inc.
 
               ONE STATE FARM PLAZA, BLOOMINGTON, ILLINOIS 61710

                 |         Services: (309) 766-2029         |
                 |------------------------------------------|
                 |       For Price Information Only:        |

                 --------------------------------------------
 
                    Offered to the Agents and Employees of
             the State Farm Insurance Companies and their families
 
         The investment objective of the Fund is the realization over
         a period of years of the highest yield consistent with
         relative price stability (relatively low volatility). The
         Fund seeks to achieve its investment objective through
         investment in high quality debt securities with primarily
         short-term (less than five years) and intermediate-term
         (five to fifteen years) maturities.
 
         Shares of the Fund are offered at their net asset value.
         There is no sales charge. The Fund is not a "money market"
         fund, and the purchase and redemption price of its shares
         changes from day to day.
 
              --------------------------------------------------  

         This prospectus contains information you should know before
         investing in the Fund. Please read it and keep it for future
         reference. A Statement of Additional Information dated 
         April 1, 1996 containing further information about the Fund, 
         which is incorporated herein by reference, has been filed with 
         the Securities and Exchange Commission. You can obtain a copy 
         without charge by writing to State Farm Investment Management 
         Corp., One State Farm Plaza, Bloomington, Illinois 61710 or by 
         calling the shareowner services number stated above.

you by increasing the Fund's investment return.

                                   THE FUND
 
  The Fund is a no-load, open-end, diversified, management investment company
(mutual fund). The Fund is a no-load fund, which means that it imposes no
sales charges or commissions. The Fund is "open-end" because it continuously
offers its shares for sale and redeems its shares upon request of the
shareowners.

  The Fund makes available to investors an investment portfolio of short-term
and intermediate-term high quality debt securities under the continuous
supervision of experienced investment management. By combining individual
shareowner investments into a pool of assets, the Fund is able to invest in
securities which require sizable minimum purchases, but often provide
investors with higher yields than securities purchasable in smaller amounts.
Through ownership of shares of the Fund, as contrasted with ownership of a
number of individual securities, shareowners are relieved of many details in
the selection and management of their investments and the safeguarding of
securities, and their bookkeeping and income tax records are greatly
simplified. In addition, the Fund provides its shareowners with liquidity, as
shares can normally be redeemed at any time at their net asset value. However,
ownership of shares of the Fund does not constitute a complete financial
program. The Fund is intended to serve primarily as an interim investment
medium, pending the shareowner's commitment of the funds to longer-term
investments or to other uses.
 
                      INVESTMENT OBJECTIVE AND POLICIES
 
  The investment objective of the Fund is the realization over a period of
years of the highest yield consistent with relative price stability
(relatively low volatility). The Fund seeks to achieve its investment
objective through investment in high quality debt securities with short-term
and intermediate-term maturities.

  In attempting to achieve this objective, the Fund may invest its assets in
the following types of investments:
 
  (1) Obligations of or guaranteed by the U.S. Government, its agencies or
instrumentalities ("U.S. Government obligations") which may be supported by
the full faith and credit of the U.S. Treasury or may be supported only by the
credit of the particular agency or instrumentality;

  (2) Corporate debt securities which are either rated A or better by Moody's
Investors Service, Inc. ("Moody's") or Standard & Poor's Corporation
("S & P"), or deemed by the Fund's investment manager, State Farm Investment
Management Corp. ("Manager"), to be of comparable quality (see "Appendix,
Description of Ratings" in the Statement of Additional Information);

  (3) Commercial paper and other money market instruments rated as Prime-1,
Prime-2 or Prime-3 by Moody's (see "Appendix, Description of Ratings" in the
Statement of Additional Information).

  Cash may be accumulated in an interest-bearing demand bank savings account
as a temporary measure pending investment in securities.

  Subsequent to its purchase by the Fund a security may no longer be rated or
its rating may be reduced below the minimum required for purchase by the Fund.
Neither occurrence will automatically require the elimination of the security
from the Fund's portfolio, but the Manager will consider the reasons for the
change in determining whether to retain the security in the portfolio.

  The Fund's investments will typically be distributed in varying amounts
among securities maturing in up to six or seven years from the time of
purchase, but occasionally may extend to securities maturing in no more than
fifteen years from the time of purchase. The average maturity of all
investments owned by the Fund will be changed from time to time on the basis
of the Manager's judgment as to prospective yields and price changes among
securities of different qualities, rates of interest and maturities.

  Yields on securities of comparable quality are usually higher for issues
with longer maturities than for those with shorter maturities. An increase in
interest rates will usually reduce the value of the Fund's investments and a
decline in interest rates will usually increase their value. In seeking to
achieve relative price stability over time, the Manager may choose to forego
the higher yields available on securities with longer maturities in favor of
the more limited price volatility of securities with shorter maturities.

  At certain times, yields available from securities with shorter maturities 
may exceed those on securities of comparable quality but longer maturities. When
these bond market conditions prevail, the Manager may choose to forego the
higher yield and greater price stability of short-term securities if in its
judgment a higher average yield over time will result from investing in issues
with longer maturities.

<PAGE>
 
  The Fund's investment objective as set forth in the first paragraph of
"Investment Objective and Policies" may not be changed without the approval
of the shareowners. However, the investment policies followed in seeking that
investment objective may be altered from time to time without shareowners'
approval.
 
                               INVESTMENT RISKS
 
  Risks are inherent in all securities investments, including mutual funds.
The Fund seeks to achieve relative price stability by investing in high
quality debt securities with primarily short-term and intermediate-term
maturities. However, inherent in the ownership of debt securities is the risk
that the issuer may be unable to make interest and principal payments when
due. The net asset value per share of the Fund may decrease if prevailing
interest rates rise in relation to the interest rates on the Fund's portfolio
securities. There can be no assurance that the objective of the Fund will be
achieved.
 
                           INVESTMENT RESTRICTIONS
 
  The Fund will not:

  (1) Invest more than 5% of the value of its total assets in securities of
any one issuer except U.S. Government obligations, which may be purchased
without limitation;

  (2) Purchase more than 10% of any class of securities of any one issuer
except U.S. Government obligations;

  (3) Invest more than 5% of its total assets (at the time of the investment)
in securities of companies with records of less than three years continuous
operation, including that of predecessors;

  (4) Invest more than 25% of the value of its total assets in any one
industry except that the Fund may invest more than 25% of the value of the
Fund's total assets in certificates of deposit or bankers' acceptances of U.S.
commercial banks when deemed advisable in view of yield differentials and
money market conditions (this restriction is not applicable to securities issued
or guaranteed by the U.S. Government, its agencies or instrumentalities).

  The policies described in the above paragraph, which cannot be changed
without the approval of a majority of the outstanding shares (as defined in
the Investment Company Act of 1940), are some of the important restrictions
upon investments of the Fund. All of the Fund's investment restrictions are
set forth in the Statement of Additional Information.
 
                           PURCHASE OF FUND SHARES
 
  Shares of the Fund may be purchased by agents and employees of the State
Farm Insurance Companies and members of their families.

  To open an account eligible investors should complete and sign the Application
furnished with this prospectus and mail it to State Farm Investment Management
Corp. ("Manager") together with either a check (minimum $50) made payable to
State Farm Investment Management Corp., or a compensation deduction
authorization, or both. Agents and employees may authorize a compensation
deduction (minimum $20) through the State Farm Insurance Companies by completing
the Compensation Deduction Authorization section of the Application.

  Subsequent investments (minimum $50) may be made at any time by mailing to
the Manager a check accompanied by the detachable purchase form at the bottom
of the confirmation. Similarly, agents and employees may authorize, change or
cancel a compensation deduction by completing and signing the reverse side of
the detachable purchase form and mailing it to the Manager. The Fund will
accept investments and compensation deduction changes by letter from a
shareowner which provides clear instructions and indicates the account
registration and account number.

  The Fund will invest the entire dollar amount of each purchase in full and
fractional shares of the Fund at the net asset value next determined after the
order to purchase is received and accepted by the Manager. Unless otherwise
instructed, all income dividends and capital gain distributions will be
reinvested in full and fractional shares. However, a shareowner may request that
income dividends and capital gain distributions be paid in cash. Stock
certificates will not be issued unless the shareowner requests a certificate in
writing. Certificates will be issued for full shares only.

  A confirmation of each transaction, except purchases by compensation
deduction, will be mailed to the shareowner by the Manager. A confirmation of
purchases by compensation deduction will be mailed to each shareowner promptly
after the end of each calendar quarter.

                                      -4-
<PAGE>
 
  The Fund reserves the right, in its sole discretion, to reject purchases
when, in the judgment of management, the purchase would not be in the best
interest of the Fund. No order to purchase shares is binding on the Fund until
it has been confirmed in writing and payment has been received by the Fund.
 
                        SYSTEMATIC WITHDRAWAL PROGRAM
 
  A shareowner owning $5,000 or more of the Fund's shares at the current net
asset value may provide for the payment of a specified dollar amount from the
shareowner's account to the shareowner or a designated payee monthly,
quarterly or annually.

  A shareowner who has a systematic withdrawal program is not permitted to
participate in the compensation deduction plan. The Fund reserves the right to
amend the systematic withdrawal program on 30 days' notice. The program may be
terminated at any time by the shareowner or the Fund. Additional information
may be obtained by contacting State Farm Investment Management Corp., One
State Farm Plaza, Bloomington, Illinois 61710.
 
                               RETIREMENT PLANS
 
INDIVIDUAL RETIREMENT ACCOUNT PLAN -- A prototype Individual Retirement Account
Plan ("IRA") is available through which investors may invest in the Fund and
certain other State Farm funds. Eligible investors who wish to establish an
IRA may request copies of the plan and related documents, including a
disclosure statement which the Internal Revenue Service requires to be
furnished to individuals who are considering adopting an IRA, from State Farm
Investment Management Corp., One State Farm Plaza, Bloomington, Illinois
61710. Commerce Bank acts as custodian of the Plans. The custodian currently
assesses a fee of $1.00 per year per plan participant.
 
Shares of the Fund and other State Farm mutual funds may be used as an
investment in other IRAs, SEP-IRAs, or other retirement plans (including Keogh
plans, corporate profit-sharing and money purchase plans, and 401(k) plans)
established by or for the benefit of individuals eligible to buy shares of the
Fund. Arrangements for establishment of a retirement plan must be made
directly with the investor's selected trustee or custodian. The Fund does not
offer prototypes of these plans.
 
                       DETERMINATION OF NET ASSET VALUE
 
  The net asset value per share of the Fund is determined as of 3:00 p.m.
Bloomington, Illinois time on Monday through Friday exclusive of the following
federal holidays: New Year's Day, President's Day, Good Friday, Memorial Day,
Independence Day, Labor Day, Thanksgiving Day and Christmas Day. The Fund need
not compute a net asset value on any day when no purchase or redemption order
has been received by the Manager or the Fund. The net asset value per share is
computed by dividing the value of the Fund's portfolio securities, plus any
cash and other assets of the Fund, less all liabilities of the Fund, by the
number of shares outstanding. Interest earned on portfolio securities and
expenses, including fees payable to the Manager, are accrued daily.
 
  In determining the net asset value per share of the Fund, long-term debt
securities and U.S. Treasury bills are valued at a fair market value by a
pricing service approved by the Board of Directors. Short-term debt
securities, other than U.S. Treasury bills, are valued on an amortized cost
basis. Securities for which the Board of Directors believes the value obtained
by the above procedures does not reflect a fair value, and all other assets,
are valued at a fair value determined in good faith by the Board of Directors.
 
                          REDEMPTION OF FUND SHARES
 
  The Fund will redeem shares from a shareowner's account at the net asset
value next determined after receipt by the Fund of a proper request for
redemption.

  Requests for redemption of shares in the Fund may be made in writing or by
telephone if the shareowner has so indicated on the application or previously
completed a Telephone Redemption Authorization Form. These redemption methods 
are explained in detail below.

  BY WRITTEN REQUEST -- Shareowners may redeem all or any portion of their
shares by sending a written request to: State Farm Investment Management
Corp., One State Farm Plaza, Bloomington, Illinois 61710. A redemption request
must clearly identify the exact name(s) in which the account is registered,
the account number and the number of shares or dollar amount to be redeemed.
Also, any stock certificates representing the shares to be redeemed must be
returned, in proper form for cancellation, along with the redemption request.
It is suggested that stock certificates returned for cancellation be sent by
certified 

                                      -5-
<PAGE>
 
mail, return receipt requested. The request must be properly signed
by each shareowner of record, including each joint holder of a joint account.
The Fund reserves the right to require further documentation in order to
verify the validity of the redemption request.

  On a redemption of $50,000 or more, the signature of the registered
shareowner must be guaranteed as described below in the section entitled
Signature Guarantee.

  Proceeds of redemption by written request normally will be sent by check to
the registered shareowner's address of record. However, upon specific
instructions included in the redemption request, proceeds may be sent to
another payee or to an address other than the address of record.

  BY TELEPHONE -- Shareowners can redeem by telephone at (309) 766-2029 up to
$50,000 of their uncertificated shares if the proceeds are to be mailed to the
address of record, or they can redeem up to the entire value of their
uncertificated shares if the proceeds are to be wired to a pre-designated bank
account. Shareowners cannot redeem shares by telephone if stock certificates are
held for those shares. Shareowners may not utilize this method of redemption
unless they have so elected on the application or until a completed
Authorization Form for Telephone Redemption and Exchange Privileges
("Authorization Form") has been filed. When this election is made by submitting
an Authorization Form, the signature of the shareowner must be guaranteed (see
"Signature Guarantee"). Further documentation may be required from corporations,
partnerships, trusts and other entities. Telephone redemption is not available
for IRA accounts.

  If elected by the shareowner, proceeds of telephone redemptions of $2,500 or
more will be wired to a bank as directed in the Telephone Redemption election.
The cost per wire transfer (currently $7.50) will be deducted from the
redemption proceeds. A similar charge may be assessed by the shareowner's bank.
In order to change the bank or account designated to receive proceeds, a written
request must be sent to State Farm Investment Management Corp., One State Farm
Plaza, Bloomington, Illinois 61710. Such requests must be signed by each
shareowner, with each signature guaranteed as described in the section entitled
Signature Guarantee.

  Telephone redemption proceeds of less than $2,500 and proceeds of up to
$50,000 of all telephone redemptions by shareowners not electing wire transfer
will be sent by check to the registered shareowner at the address of record.

  During periods of volatile economic and market conditions, a shareowner may
have difficulty making a redemption request by telephone, in which case
redemption requests would have to be made in writing.

  By electing the Telephone Redemption Privilege, the shareowner authorizes
the Manager to act upon an instruction by telephone to redeem shares from any
account for which such services have been elected. The Manager and the Fund
will employ reasonable procedures, including tape recording of telephone
instructions and providing written confirmation of each resulting transaction,
to confirm that telephone instructions are genuine. If the Manager and the
Fund fail to employ such procedures, they may be liable for any losses due to
unauthorized or fraudulent instructions. However, the Fund, its transfer agent
and their respective officers, directors, employees and agents will not be
liable for acting upon instructions given under the authorization when
reasonably believed to be genuine. In such case, the shareowner will bear the
risk of loss in the event of a fraudulent telephone redemption transaction. To
reduce that risk, proceeds of telephone redemptions will be sent only by check
payable to the shareowner of record to the shareowner's address of record or
wired to a pre-designated bank account.

  Although the Authorization Form authorizes the Fund or its adviser to
tape-record all telephone instructions, the Fund may not honor telephone
instructions unless permission to record is confirmed by the caller.

  Once the Telephone Redemption Privilege with a State Farm mutual fund has
been established by a shareowner, it may be established at the request of the
shareowner in any identically registered new account in any other State Farm
mutual fund offering the Telephone Redemption Privilege by the exchange of
shares of the first fund for those of the second fund by use of the Exchange
Privilege.

  REDEMPTION GENERALLY -- The Fund will generally redeem shares in cash (by
check or bank wire). Redemptions of more than $500,000 during any 90-day period
by one shareowner will normally be paid in cash, but may be paid wholly or
partly by a distribution in kind of securities. If a redemption is paid in kind,
the redeeming shareowner may incur brokerage fees in selling the securities
received.

                                      -6-
<PAGE>
 
  Payment for shares redeemed will be mailed or wired within seven days after
the Fund receives a redemption request, either written or by telephone, in
proper form (including stock certificates, if any). However, if the Fund is
requested to redeem shares within several days after they have been purchased,
the Fund may delay mailing the redemption proceeds until it can verify that
payment of the purchase price for the shares has been, or will be, collected.
If the shareowner requests payment by wire, the cost of the wire transfer
(currently $7.50) will be deducted from the redemption proceeds.

  A redemption is treated as a sale for federal income tax purposes. A
shareowner's redemption proceeds may be more or less than the shareowner's
cost depending upon the net asset value at the time of the redemption and, as
a result, the shareowner may realize a capital gain or loss. Gain or loss is
computed on the difference between the fair market value of the shares
redeemed and their cost basis. If shares of the Fund are purchased during the
30 days before or after a redemption, the Internal Revenue
Code wash sale rules might apply.

  Although it is not anticipated that the Fund will impose a redemption fee,
the Fund reserves the right to charge a redemption fee not to exceed one
percent of the redemption price.

  The Fund may suspend the right of redemption or postpone a redemption
payment more than seven days during any period when (a) the New York Stock
Exchange is closed for other than customary weekend and holiday closings, (b)
trading on that Exchange is restricted, (c) an emergency exists making
disposal of securities owned by the Fund or valuation of its assets not
reasonably practicable, or (d) the Securities and Exchange Commission has by
order permitted such suspension for the protection of shareowners of the Fund;
provided that applicable rules and regulations of the Securities and Exchange
Commission shall govern as to whether any condition prescribed in (b) through
(d) exists.
 
                             SIGNATURE GUARANTEE
 
  A signature guarantee is a written representation, signed by an officer or
authorized employee of the guarantor, that the signature of the shareowner is
genuine. The guarantor must be an institution authorized to guarantee
signatures by applicable state law. Such institutions include banks,
broker-dealers, savings and loan associations and credit unions.

  The signature guarantee must appear, together with the signature of each
registered owner, either: (1) on the written request for redemption, which
clearly identifies the exact name(s) in which the account is registered, the
account number and the number of shares or the dollar amount to be redeemed;
or (2) on a separate "stock power," an instrument of assignment which should
specify the total number of shares to be redeemed (this stock power may be
obtained from most banks and stockbrokers); or (3) on the back of each stock
certificate tendered for redemption; or (4) on the Telephone Redemption and
Exchange Privileges Authorization Form.
 
                           EXCHANGE OF FUND SHARES
 
  GENERAL -- A shareowner may redeem part or all of the shares in the
shareowner's account and purchase shares of another State Farm mutual fund
without charge, by meeting the established redemption procedures and minimum
subscription requirements of that fund. A written exchange request must be
accompanied by a properly completed application for the fund being purchased if
an account in the new fund has not previously been established. A telephone
exchange request can be transacted as described under "Telephone Exchange
Privilege".

  An exchange transaction is a sale and purchase of shares for federal tax
purposes, and may result in capital gain or loss. Before making an exchange, a
shareowner should obtain the prospectus for the fund to be purchased from the
Manager at One State Farm Plaza, Bloomington, Illinois 61710, and read it
carefully.

  TELEPHONE EXCHANGE PRIVILEGE -- Shareowners who wish to use the Telephone
Exchange Privilege, which permits them to exchange by telephone shares of the
Fund for those of another fund managed by State Farm Investment Management
Corp., must so elect on the application or complete the Authorization Form,
have their signatures guaranteed and mail the form to the Fund.

  Once the Telephone Exchange Privilege has been granted by the Fund, the
shareowner may telephone the Fund and request an exchange for any amount
meeting or exceeding the applicable minimum investment of the fund being
purchased. The shareowner must identify the existing account by designating
the Fund's name, registration of the account and account number, and must
specify the dollar amount or number of shares to be exchanged and 

                                      -7-
<PAGE>
 
the fund to which the exchange should be made. The registration of the account
to which an exchange is made must be exactly the same as that of the Fund
account from which an exchange is made. If the shareowner has not established an
account in the fund to which the exchange is to be made, a new account will be
opened automatically and will carry the same registration as the Fund account
from which the exchange is made; accordingly, the Telephone Exchange Privilege
will also apply to the fund being purchased. The Fund's transfer agent's records
of such instructions are binding.
  The Manager and the Fund will employ reasonable procedures, including tape
recording of telephone instructions and providing written confirmation of each
resulting transaction, to confirm that telephone instructions are genuine. If
the Manager and the Fund fail to employ such procedures, they may be liable for
any losses due to unauthorized or fraudulent instructions. However, the Fund,
its transfer agent, and their respective officers, directors, employees and
agents will not be liable for acting upon instructions given by any person under
the Telephone Exchange Privilege when reasonably believed to be genuine. In such
case, the shareowner will bear the risk of loss in the event of a fraudulent
telephone exchange transaction. To reduce the risk of loss, the registration of
the account into which shares are exchanged must be identical with the
registration of the originating account.
  The Telephone Exchange Privilege is not available for shares represented by a
certificate or if good payment for shares being redeemed has not been received.
(The other funds into which exchanges may be made have adopted similar
policies.)
  During periods of volatile economic and market conditions, a shareowner may
have difficulty making an exchange request by telephone, in which case exchange
requests would have to be made in writing. The Fund reserves the right at any
time to suspend, limit, modify or terminate the telephone exchange privilege,
but will not do so without giving shareowners at least 30 days' prior written
notice.
 
                            MANAGEMENT OF THE FUND
 
  The Board of Directors has overall management responsibilities for the Fund.
However, the Fund has engaged State Farm Investment Management Corp., One State
Farm Plaza, Bloomington, Illinois 61710, as Manager to provide professional
investment management for the Fund.
  The Fund's portfolio is managed by a team consisting of Kurt Moser and John
Concklin. Mr. Moser has participated in the Fund's portfolio management since
1988. Mr. Concklin became part of the Fund's portfolio management team in 1995.
  Presently, Mr. Moser is a Director and a Vice President of the Manager. In
addition to his offices with the Manager, Mr. Moser has also held the following
positions during the past five years: Vice President of the Fund since 1990;
Director of State Farm Life Insurance Company and State Farm Fire and Casualty
Company since 1991; Vice President of State Farm Life Insurance Company since
1989, and Vice President--Investments of State Farm Mutual Automobile Insurance
Company and State Farm and Casualty Company since 1989.
  Mr. Concklin is an Investment Officer of the Manager. In addition to his
office with the Manager, Mr. Concklin has also held the following positions
during the last five years: Vice President--Fixed Income, State Farm Life
Insurance Company, State Farm Mutual Automobile Insurance Company and State Farm
Fire and Casualty Company since 1995; and Investment Officer for State Farm Life
Insurance Company, State Farm Mutual Automobile Insurance Company and State Farm
Fire and Casualty Company from 1986 through 1995.
  Since its inception in 1967, the Manager's sole business has been to act as
investment adviser, principal underwriter, transfer agent and dividend
disbursing agent for the State Farm mutual funds.
  The Manager is wholly-owned by State Farm Mutual Automobile Insurance Company.
  For the fiscal year ended November 30, 1995 management fees paid by the Fund
amounted to 0.18% of the Fund's average net assets.
 
                      DIVIDENDS, DISTRIBUTIONS AND TAXES
 
  The Fund declares a dividend each day from its net investment income,
distributable at the end of each calendar quarter. Shares begin to earn
dividends on the day following the date of purchase. Net realized capital gains,
if any, are distributed annually. All distributions are automatically reinvested
in shares of the Fund at the net asset value on the payment date, except that
any shareowner may elect to receive dividends and capital gains distributions in
cash, upon signed written request received by the Manager. If the entire amount
in a shareowner's account is redeemed, dividends credited to that account
through the day of redemption are paid with the proceeds of redemption.

  Distributions from net investment income and from short-term capital gains, if
any, are taxable to shareowners as ordinary income, whether received in cash or
additional shares.
  Distributions of long-term capital gains are taxable to shareowners as long-
term capital gains, whether received in cash or additional shares and regardless
of the period of time the shares have been held.
  If a shareowner is not subject to tax on its income, it will not be required
to pay tax on amounts distributed to it. Shareowners must provide their social
security or tax identification number and furnish appropriate certification.
Otherwise, IRS regulations require the Fund to withhold 31% from taxable
distributions payable to accounts whose owners have not complied. Information
concerning the tax status of dividends and distributions is mailed to
shareowners annually.
  Because this section is not intended to be a full discussion, shareowners may
wish to consult their tax advisers regarding the tax consequences of investments
in the Fund.
 
                        ORGANIZATION AND CAPITAL STOCK

                            FINANCIAL INFORMATION
 
  Please refer to the financial statements (including Financial Highlights),
notes thereto and Report of Independent Auditors (all of which are "Financial
Information") contained in the Fund's annual report for the fiscal year ended
November 30, 1995, a copy of which accompanies this Statement of Additional
Information. This Financial Information (but no other material from the annual
report) is incorporated by reference in this Statement of Additional
Information. Additional copies of the annual report may be obtained by writing
or telephoning the Fund, (309) 766-2029.
 
                      INVESTMENT OBJECTIVE AND POLICIES
 
  The investment objective of the Fund is the realization over a period of
years of the highest yield consistent with relative price stability
(relatively low volatility), from high quality debt securities with short-term
and intermediate term maturities.

  In attempting to achieve this objective, the Fund may invest its assets in
the following types of investments:

  (1) Obligations of or guaranteed by the U.S. Government, its agencies or
instrumentalities ("U.S. Government obligations") which may be supported by
the full faith and credit of the U.S. Treasury or may be supported only by the
credit of the particular agency or instrumentality;

  (2) Corporate debt securities which are either rated A or better by Moody's
Investors Service, Inc. ("Moody's") or Standard & Poor's Corporation ("S & P") 
or deemed by the Fund's investment manager, State Farm Investment Management
Corp. ("Manager"), to be of comparable quality (see "Appendix, Description of
Ratings"); and

  (3) Commercial paper and other money market instruments rated as Prime-1,
Prime-2, or Prime-3 by Moody's (see "Appendix, Description of Ratings").

  Cash may be accumulated in an interest-bearing demand bank savings account
as a temporary measure pending investment in securities.

  Subsequent to its purchase by the Fund an issue may no longer be rated or
its rating may be reduced below the minimum required for purchase by the Fund.
Neither occurrence will automatically require the elimination of the issue
from the Fund's portfolio, but the Manager will consider the reasons for the
change in determining whether to retain the issue in the portfolio.

  The Fund's investments will typically be distributed in varying amounts
among issues maturing in up to six or seven years from the time of purchase,
but occasionally may extend to issues maturing in no more than fifteen years
from the time of purchase. The average maturity of all investments owned by the
Fund will be changed from time to time on the basis of the Manager's judgment as
to prospective yields and price changes among issues of different qualities,
rates of interest and maturities.

  Yields on securities of comparable quality are usually higher for issues
with longer maturities than for those with shorter maturities. An increase in
interest rates will usually reduce the value of the Fund's investments and a
decline in interest rates will usually increase their value. In seeking to
achieve relative price stability over time, the Manager may choose to forego
the higher yields available on issues with longer maturities in favor of the
more limited price volatility of issues with shorter maturities.

  At certain times, yields available from issues with shorter maturities may
exceed those on issues of comparable quality but longer maturities. When these
bond market conditions prevail, the Manager may choose to forego the higher
yield and greater price stability of short-term issues if, in its judgment, a
higher average yield, over time, will result from investing in issues with
longer maturities.

  The Fund expects that its annual portfolio turnover rate will usually be
less than 100%, but the rate of turnover will not be a limiting factor when
the Manager considers it advisable to sell or purchase securities. The annual
portfolio turnover rate would be 100%, for example, if an amount of securities
equal to the average value of all portfolio securities during the year were
sold and reinvested, exclusive in both cases of all securities with maturities
at time of acquisition of one year or less. Historical portfolio turnover rate
information is set forth in the Fund's prospectus in the Financial Highlights
table which is incorporated herein by reference.

  The Fund's investment objective may not be changed without the approval of
the shareowners. However, the investment policies followed in seeking that
investment objective may be altered from time to time without shareowners'
approval.

                            INVESTMENT RESTRICTIONS
 
  The Fund is subject to certain restrictions upon its investments which provide
that the Fund may not:

  (1) Invest more than 5% of the value of the Fund's total assets in securities
of any one issuer except securities issued or guaranteed by the U.S. Government,
its agencies or instrumentalities, which may be purchased without limitation;

  (2) Borrow money, except from banks for temporary or emergency purposes and
not for investment purposes, and then only in an amount not exceeding 5% of the
value of the Fund's total assets at the time of borrowing;

  (3) Pledge, mortgage or hypothecate the Fund's assets, except that, to secure
borrowings permitted by subparagraph (2) above, the Fund may pledge securities
having a market value not exceeding 10% of the Fund's net asset value;

  (4) Underwrite any securities issued by other persons;

  (5) Purchase or sell real estate, but the Fund may invest in securities
secured by real estate or interests therein;

  (6) Purchase or sell commodities or commodities contracts, or interests in
oil, gas or other mineral exploration or development programs;

  (7) Make loans to others (except to the extent that the purchase of debt
securities may be deemed the making of a loan);

  (8) Make short sales of securities or purchase any securities on margin,
except for such short-term credits as are necessary for the clearance of
transactions, or purchase or sell any put or call options or combinations
thereof;

  (9) Purchase or retain for the portfolio of the Fund the securities of any
issuer, if, to the Fund's knowledge, those directors and officers of the Fund
who individually own more than 1/2 of 1% of the outstanding securities of such
issuer together own more than 5% of such outstanding securities;

  (10) Purchase more than 10% of any class of securities of any one issuer (for
this purpose all indebtedness of an issuer shall be deemed a single class)
except U.S. Government obligations;

  (11) Purchase securities subject to restrictions on disposition under the
Securities Act of 1933;

  (12) Purchase securities of other investment companies or investment trusts,
except by purchases in the open market involving no commission or profit (other
than the customary broker's commission) to a sponsor or dealer, and then only in
an amount up to 5% of the value of the Fund's total assets, or except as a part
of a plan of merger or consolidation;

  (13) Invest in the securities of a company for the purpose of exercising
management or control;

  (14) Invest more than 5% of the market value of the Fund's total assets (at
the time of the investment) in securities of companies with records of less than
three years' continuous operation, including that of predecessors;

  (15) Invest more than 25% of the value of the Fund's total assets in any one
industry except that the Fund may invest more than 25% of the value of the
Fund's total assets in certificates of deposit or bankers' acceptances of U.S.
commercial banks when deemed advisable in view of yield differentials and money
market conditions (this restriction is not applicable to securities issued or
guaranteed by the U.S. Government, its agencies or instrumentalities).

  For purposes of restrictions numbered 1, 9 and 10 above, the Fund will
classify the issuer or issuers of a security according to the entity or entities
which constitute the source of payment of interest and principal on the
security.

  Other than for purposes of restriction number 3 above, if a percentage
restriction is not violated at the time of investment or borrowing, a change in
the value of the Fund's net assets or in the outstanding securities of an issuer
will not result in a violation of the restriction.

  These investment restrictions have been adopted by the Fund and may not be
changed without the consent of the shareowners holding a majority of the shares.
A majority of the shares, as used in this Statement of Additional Information
and in the Prospectus, means the vote of (i) 67% or more of the shares present
and entitled to vote at a meeting, if the holders of more than 50% of the shares
are present or represented by proxy, or (ii) more than 50% of the shares,
whichever is less.

                    PURCHASE AND REDEMPTION OF FUND SHARES
 
  Purchases and redemptions of Fund shares are discussed in the prospectus under
the headings "Purchase of Fund Shares", "Systematic Withdrawal Program",
"Retirement Plans", "Redemption of Fund Shares" and "Exchange of Fund Shares"
and that information is incorporated herein by reference.
 
                       DETERMINATION OF NET ASSET VALUE
 
  Determination of net asset value is set forth in the prospectus under the
heading "Determination of Net Asset Value" and that information is incorporated
herein by reference.
 
                    INVESTMENT ADVISORY AND OTHER SERVICES
 
  The Fund has an Investment Advisory and Management Services Agreement, a
Transfer Agent Agreement and an Underwriting Agreement with State Farm
Investment Management Corp., One State Farm Plaza, Bloomington, Illinois 61710.
There is a separate Service Agreement among the Fund, the Manager and State Farm
Mutual Automobile Insurance Company ("Auto Company"). Each of these four
agreements may be continued beyond its current term only so long as such
continuance is specifically approved at least annually by the Board of Directors
of the Fund or by vote of a majority of the outstanding shares of the Fund and,
in either case, by vote of a majority of the directors who are not interested
persons of any party to such agreement, except in their capacity as directors of
the Fund, cast in person at a meeting called for the purpose of voting on such
approval. Each agreement may be terminated upon 60 days' written notice by any
of the parties to the agreement, or by a majority vote of the outstanding
shares, and will terminate automatically upon its assignment by any party.

  The Manager is also the investment manager, transfer agent, dividend
disbursing agent and underwriter for State Farm Growth Fund, Inc., State Farm
Balanced Fund, Inc. and State Farm Municipal Bond Fund, Inc. There are similar
agreements among those funds, the Manager and the Auto Company, except that the
Investment Advisory and Management Services Agreements with State Farm Growth
Fund, Inc. and State Farm Balanced Fund, Inc. provide for investment advisory
fees at annual rates different from those applicable to the Fund.

  Since its inception in 1967, the Manager's sole business has been to act as
investment adviser, principal underwriter, transfer agent and dividend
disbursing agent for the State Farm mutual funds.

  The Manager is wholly-owned by State Farm Mutual Automobile Insurance Company,
which is an Illinois mutual insurance company.

  Messrs. Rust, Joslin, Grimes, Moser, Tipsord, Chevalier and Ms. Dysart are
directors and/or officers of the Fund, the Manager and the other State Farm
mutual funds (see "Directors and Officers").
 
                         MANAGEMENT SERVICES AGREEMENT
 
  Pursuant to an Investment Advisory and Management Services Agreement, the
Manager: (1) acts as the Fund's investment adviser; (2) manages the Fund's
investments; (3) administers the Fund's business affairs; (4) provides clerical
personnel, suitable office space, necessary facilities and equipment and
administrative services; and (5) permits its officers and employees to serve as
directors, officers and agents of the Fund, without compensation from the Fund,
if duly elected or appointed.

  The agreement requires the Fund to pay: (1) the fees and expenses of
independent auditors, legal counsel, the custodian, the transfer agent, the
registrar, the dividend disbursing agent and directors who are not affiliated
with the Manager; and (2) the cost of preparing and distributing stock
certificates, proxy materials, reports and notices to shareowners, brokerage
commissions, interest, taxes, federal securities registration fees and
membership dues in the Investment Company Institute or any similar organization.
The Manager is required to pay all other Fund expenses.

  As compensation for the services and facilities furnished, the Fund pays a
management fee (computed on a daily basis and paid quarterly) at the annual rate
of .20% of the first $50 million of average net assets, .15% of the next $50
million of average net assets and .10% of the average net assets in excess of
$100 million.

                                      -4-

<PAGE>
 
However, the management fee will be reduced, or the Manager will reimburse the
Fund, by any amount necessary to prevent the Fund's total expenses (excluding
taxes, interest, extraordinary litigation expenses, brokerage commissions and
other portfolio transaction costs) from exceeding .40% of the average net assets
of the Fund on an annual basis.

  For the fiscal years ended November 30, 1995, 1994 and 1993, the Manager
earned $170,812, $176,259, and $164,292, respectively, for its services as
investment adviser to the Fund. Neither the Manager nor any affiliated company
receives any brokerage commissions from the Fund as such business is transacted
with non-affiliated broker-dealers.

  Some affiliated companies of the Manager (including Auto Company) and the
other State Farm funds managed by the Manager carry on extensive investment
programs. Securities considered as investments for the Fund may also be
appropriate for the accounts of one or more of such companies. Although
investment decisions for the Fund are made independently from those for such
other companies, securities of the same issuer may be acquired, held or disposed
of by the Fund and one or more of such other companies at or about the same
time, if consistent with the investment objectives and policies of the
respective parties. When both the Fund and one or more of such other companies
are concurrently engaged in the purchase or sale of the same securities, the
transactions are allocated as to amount and price in a manner considered
equitable to the Fund. In some cases this procedure may affect the price or
amount of the securities as far as each party is concerned. It is the opinion of
the Directors of the Fund, however, that the benefits available to the Fund
outweigh any possible disadvantages that may arise from such concurrent
transactions.

  The obligation of performance under the management agreement between the
Manager and the Fund is solely that of the Manager, for which the Auto Company
assumes no responsibility.
 
                              SERVICE AGREEMENT
 
  Under the Service Agreement, the Auto Company makes available to the Manager
the services, on a part-time basis, of employees of the Auto Company engaged in
its investment operations, and also certain other personnel, services and
facilities to enable the Manager to perform its obligations to the Fund. The
Manager reimburses the Auto Company for such costs, direct and indirect, as are
fairly attributable to the services performed and the facilities provided by the
Auto Company under the Service Agreement. Accordingly, the Fund makes no payment
to the Auto Company under the Service Agreement.
 
                            UNDERWRITING AGREEMENT
 
  Pursuant to the Underwriting Agreement the Manager: (1) is the underwriter of
the Fund's shares; (2) acts as agent of the Fund in the continuous sale of its
shares; (3) prepares and distributes literature relating to the Fund and its
investment performance; (4) distributes and pays for the printing of the Fund's
prospectus; (5) circulates advertising and public relations materials; and (6)
pays the cost of qualifying and maintaining the qualification of the Fund's
shares for sale under the securities laws of the various states.

  The Manager receives no discount, commission or other compensation as
underwriter.
 
                           TRANSFER AGENT AGREEMENT
 
  The Transfer Agent Agreement appoints the Manager as the Fund's transfer agent
and dividend disbursing agent. Under the terms of the agreement, the Manager:
(1) maintains all shareowner account records; (2) prepares and mails transaction
confirmations, annual records of investments and tax information statements; (3)
effects transfers of Fund shares; (4) arranges for the issuance and cancellation
of stock certificates; (5) prepares annual shareowner meeting lists; (6)
prepares, mails and tabulates proxies; (7) mails shareowner reports; and (8)
disburses dividends and capital gains distributions. These services are
performed by the Manager at no charge to the Fund.
 
                           PERFORMANCE INFORMATION
 
  The Fund provides information on its "Average Annual Total Return" in its
annual reports to shareowners. "Average Annual Total Return" is the average
annual compounded rate of change in value represented by the percentage change
in value during a period of an investment in shares of the Fund, including the
value of shares acquired through reinvestment of all dividends and capital gains
distributions for the period.

                                      -5-

<PAGE>
 
  Average Annual Total Return is computed as follows:

                  n
    ERV = P(1 + T)
 
  Where: P = the amount of an assumed initial investment in shares of the Fund
         T = average annual total return
         n = number of years from initial investment to the end of the period
         ERV = ending redeemable value of shares held at the end of the period
 
  For example, as of November 30, 1995 the Average Annual Total Return of a
$1,000 investment in the Fund for the following periods was:

                                                     Average Annual
                                                      Total Return
                                                      ------------
            1 year..............................          11.91%
            5 years.............................           7.38
            10 years............................           7.99
 
  The Fund imposes no sales charges and pays no distribution expenses. Income
taxes are not taken into account. Performance figures quoted by the Fund are not
necessarily indicative of future results. The Fund's performance is a function
of conditions in the securities markets, portfolio management and operating
expenses. Although information about past performance is useful in reviewing the
Fund's performance and in providing some basis for comparison with other
investment alternatives, it should not be used for comparison with other
investments using different reinvestment assumptions or time periods.

  In its annual report, the Fund's performance may be compared with movements of
markets indexes, including the Lehman Brothers Intermediate Treasury Index and
the Lehman Brothers Three-Year Index.
 
                            PORTFOLIO TRANSACTIONS
 
  To date all purchases and sales of portfolio securities for the Fund have been
made on a net basis without brokerage commissions, in transactions with
securities dealers who buy and sell those securities as market makers. Market
makers earn the spread between the bid and asked prices at which they buy and
sell. The Fund may occasionally purchase new issues of securities offered by
underwriters, at prices which are marked up from the discounted prices at which
the underwriters purchase for resale. For the fiscal years ended November 30,
1995, 1994 and 1993, the Fund paid no brokerage commissions.

  The Manager's primary consideration in selecting dealers or brokers to execute
transactions is the best net price consistent with competent execution. Among
the factors considered in evaluating quality of execution are: (1) skill,
knowledge and effort required in executing particular transactions; (2) trading
and operational capability; (3) financial condition and stability; (4)
confidentiality; and (5) reliability and integrity.

  The Manager and the Auto Company perform extensive investment research, which
is used in making investment decisions for the Fund in the performance of the
Investment Advisory and Management Services Agreement, for the State Farm
Companies, and for the other State Farm funds. The availability of additional
information from a diversity of sources, some of which have in-depth knowledge
of specialized subjects, and have proven insight and acumen in economic,
financial, political and investment matters, may tend to reduce the Manager's
costs by some indeterminable amount, but more importantly is believed to provide
a quantity and range of information greater than could be generated solely
within a single advisory organization, even for a larger advisory fee. While the
State Farm Companies and the other State Farm funds, as well as the Fund, may
benefit from information obtained for the Fund with the Fund's transactions, the
Fund may also realize a benefit from information obtained for the State Farm
Companies and for other State Farm funds with their transactions.
 
                         ADDITIONAL TAX CONSIDERATIONS
 
  The Fund intends to continue to qualify as a "regulated investment company"
under Subchapter M of the Internal Revenue Code. A 4% excise tax is imposed on
the excess of the required distribution for a calendar year over the distributed
amount for such calendar year. Generally, the required distribution is the sum
of 98% of the Fund's net investment income for the calendar year plus 98% of its
capital gain net income for the

                                      -6-

<PAGE>
 
one year period ending November 30. The Fund intends to declare or distribute
dividends during the calendar year in an amount sufficient to prevent imposition
of the 4% excise tax.

  Because capital gain distributions reduce net asset value, if you purchase
shares shortly before a record date for such a distribution you will, in effect,
receive a return of a portion of your investment although the distribution will
be taxable to you. This is true even if the net asset value of your shares was
reduced below your cost. However, for federal income tax purposes your original
cost would continue as your tax basis. Any loss recognized on the disposition of
Fund shares acquired which have been held by the shareowner for six months or
less will be treated as long-term capital loss to the extent the shareowner
received a long-term capital gain distribution with respect to those Fund
shares.

  Distributions of long-term capital gains are taxable to shareowners as long-
term capital gains, whether received in cash or additional shares and regardless
of the period of time the shares have been held. Dividends and capital gains are
taxed to shareholders at the same rates. However, the distinction between
ordinary income or loss and capital gain or loss remains important for certain
tax purposes, such as a taxpayer's ability to offset losses against income.

                            DESCRIPTION OF RATINGS
                    (AS PUBLISHED BY THE RATING COMPANIES)
 
STANDARD & POOR'S BOND RATINGS

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

  AA. Bonds rated AA also qualify as high grade obligations, and in the majority
of instances differ from AAA issues only in small degree. Here, too, prices move
with the long-term money market.

  A. Bonds rated A are regarded as upper medium grade. They have considerable
investment strength but are not entirely free from adverse effects of changes 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 respond to economic conditions.
 
MOODY'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-edge". 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 most 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 comprise 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 the long-term risk appear somewhat greater than in 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.

MOODY'S COMMERCIAL PAPER RATINGS
 
  Prime-1. Commercial Paper issuers rated Prime-1 are judged to be of the best
quality. Their short-term debt obligations carry the smallest degree of
investment risk. Margins of support for current indebtedness are large or stable
with cash flow and asset protection well assured. Current liquidity provides
ample coverage of near-term liabilities and unused alternative financing
arrangements are generally available. While protective elements may change over
the intermediate or longer term, such changes are most unlikely to impair the
fundamentally strong position of short-term obligations.

  Prime-2. Issuers in the Commercial Paper market rated Prime-2 are of high
quality. Protection for short-term note holders is assured, with liquidity and
value of current assets as well as cash generation in sound relationship to
current indebtedness. They are rated lower than the best commercial papers
issuers because margins of protection may not be as large or because
fluctuations of protective elements over the near or intermediate term may be of
greater amplitude. Temporary increases in relative short term and overall debt
load may occur. Alternative means of financing remain assured.

  Prime-3. Commercial Paper issuers rated Prime-3 possess favorable investment
attributes for short-term commitment. Liquidity considerations and cash
generation provide satisfactory support for short-term debt repayment. While
near-term investors are well-protected, elements may be present which suggest
improvement or deterioration in support at some time in the future. Alternative
financing strategies have been outlined.

  Issuers rated in all three Prime categories are judged by Moody's to be
investment grade.

Dear Shareowner:

  The past fiscal year has been a good one for bond markets and investors in the
Interim Fund. Yields on U. S. Treasury securities held by your Fund have dropped
more than 200 basis points (a basis point is .01%) during the year causing the
values of the securities to increase significantly. Correspondingly, the net
asset value of the Interim Fund rose to $10.15 from $9.72, a 4.4% improvement.
The total return, which is derived by adding dividends declared by the Fund to
the change in net asset value, for the past year was 11.91%.

  The following graph compares a $10,000 investment in the Interim Fund over the
last ten years to theoretical investments of the same amount in the Lehman
Brothers Intermediate Treasury Index and the Lehman Brothers Three-year Treasury
Index:

  The fall in interest rates over the course of the year has been fueled by
evidence that growth of the U. S. economy is slowing and inflationary pressures
are slight. Furthermore, capital markets have been helped to some degree by
prospects for a program, which will hopefully be agreed upon by the President
and Congress, to eliminate the federal budget deficit over seven years.

  The prevailing mood in the bond markets is quite optimistic at the moment.
Many investors seem to be convinced that the Federal Reserve Board has done its
job well and the twin perils of inflation and recession will be avoided for a
long time leaving room for further drops in interest rates. Such a view is
comforting and may well prove to be correct, but we caution you, as investors,
against believing the future is predictable. Markets are always vulnerable to
unanticipated surprises and changes in investors' perceptions, and vulnerability
along these lines tends to be greatest when optimism is rampant.

     The general composition of the Fund's portfolio changes very little from
year to year with primary investments consisting of U. S. Treasury issues which
mature regularly over the following six years. The high quality investments held
by the Fund continue to produce a dependable flow of dividend income to
shareowners.

     As you know, the Fund declares a dividend each day from its net investment
income which is payable on the last day of the calendar quarter. All dividends
are automatically invested in shares of the Fund unless you have advised State
Farm Investment Management Corp. otherwise in writing.

Sincerely,


/s/ Kurt G. Moser

                        REPORT OF INDEPENDENT AUDITORS

The Board of Directors and Shareowners
State Farm Interim Fund, Inc.

We have audited the accompanying statement of assets and liabilities, including
the portfolio of investments, of State Farm Interim Fund, Inc. as of November
30, 1995, the related statements of operations and 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 Fund's 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
November 30, 1995, by correspondence with the custodian. 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 State
Farm Interim Fund, Inc. at November 30, 1995, the results of its operations and
changes in its 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.

1. Significant accounting policies

   Security valuation --

   Debt securities are valued using quotations provided by an independent
pricing service, except short-term debt securities having a maturity of 60 days
or less from the valuation date are valued on an amortized cost basis. Any
securities not valued as described above are valued at fair value as determined
in good faith by the Board of Directors or its delegate.


   Security transactions and interest income --

   Security transactions are accounted for on the trade date (date the order to
buy or sell is executed). Interest income is recorded on the accrual basis.
Realized gains and losses from security transactions are reported on an
identified cost basis.


   Fund share valuation, dividends and distributions to shareowners --

   Fund shares are sold and redeemed on a continuous basis at net asset value.
Net asset value per share is determined as of 3:00 p.m. Bloomington, Illinois
time on each business day other than customary weekend and holiday closings,
except that the Fund need not compute a net asset value on any day when no
purchase or redemption order has been received by the Fund. The net asset value
per share is computed by dividing the value of the Fund's investments and other
assets, less liabilities, by the number of Fund shares outstanding. The Fund
declares a daily dividend equal to its net investment income, and distributions
of such amounts are made at the end of each calendar quarter. Net realized gains
on sales of investments, if any, are distributed annually after the close of the
Fund's fiscal year.

   Dividends and distributions payable to its shareowners are recorded by the
Fund on the ex-dividend date.


   Federal income taxes --

   It is the Fund's policy to comply with the special provisions of the Internal
Revenue Code available to investment companies and, in the manner provided
therein, to distribute all of its taxable income, as well as any net realized
gain on sales of investments reportable for federal income tax purposes. The
Fund has complied with this policy and, accordingly, no provision for federal
income taxes is required.

   The accumulated net realized loss on sales of investments at November 30,
1995, amounting to $1,044,868, is available to offset future taxable gains. If
not applied, the capital loss carryover expires as follows: $14,537 in 1996,
$55,654 in 1997, $40,572 in 1998, $92,150 in 1999, $22,669 in 2000, $162,716 in
2001, $335,277 in 2002, and $321,293 in 2003.

   A capital loss carryover of $2,235 expired in 1995 and was re-classified from
Accumulated net realized loss on sales of investments to Excess of amounts
received from sales of shares over amounts paid on redemptions of shares on
account of capital.


   Custodian fees --

   Custodian fees are reduced based on the Fund's cash balances maintained with
the custodian. Beginning in 1995, in accordance with changes in the requirements
of the Securities and Exchange Commission, both gross custodian fees and the
amount by which such fees are reduced, are disclosed separately in the statement
of operations. This presentation does not affect the determination of net
investment income.

2. Transactions with affiliates

   The Fund has an investment advisory and management services agreement with
State Farm Investment Management Corp. (Manager) pursuant to which the Fund pays
the Manager an annual fee (computed on a daily basis and paid quarterly) of .20%
of the first $50 million of average net assets, .15% of the next $50 million of
average net assets and .10% of average net assets in excess of $100 million. The
Manager guarantees that all operating expenses of the Fund, including the
compensation of the Manager but excluding franchise taxes, interest,
extraordinary litigation expenses, brokerage commissions and other portfolio
transaction costs, shall not exceed .40% of average net assets annually.

   Under the terms of this agreement, the Fund incurred fees of $170,812 for
1995 and $176,259 for 1994. The Fund pays no fees for transfer agent services
provided by the Manager. The Fund does not pay any discount, commission or other
compensation for underwriting services provided by the Manager.

   Certain officers and/or directors of the Fund are also officers and/or
directors of the Manager. The Fund made no payments to its officers or directors
during the two years ended November 30, 1995, except for directors' fees of
$1,100 for 1995 and 1994, respectively, paid to the Fund's independent

Item 27.  Indemnification

          Section 2-418 of the Maryland General Corporation Law authorizes the
          registrant to indemnify its directors and officers under specified
          circumstances.

          Paragraph 5 of Article Seventh of the Articles of Incorporation of
          the registrant and Section 6 of Article VI of the by-laws of the
          registrant provide that the registrant shall indemnify its
          directors and officers under specified circumstances.

          Insofar as indemnification for liabilities arising under the
          Securities Act of 1933 may be permitted to directors, officers and
          controlling persons of the registrant pursuant to the foregoing
          provisions, or otherwise, the registrant has been advised that in the
          opinion of the Securities and Exchange Commission such indemnification
          is against public policy as expressed in the Act and is, therefore,
          unenforceable. In the event that a claim for indemnification against
          such liabilities (other than the payment by the registrant of expenses
          incurred or paid by a director, officer or controlling person of the
          registrant in the successful defense of any action suit or proceeding)
          is asserted by such director, officer or controlling person in
          connection with the securities being registered, the registrant will,
          unless in the opinion of its counsel the matter has been settled by
          controlling precedent, submit to a court of appropriate jurisdiction
          the question whether such indemnification by it is against public
          policy as expressed in the Act and will be governed by the final
          adjudication of such issue.

Item 28.  Business and Other Connections of Investment Adviser

          The information in the prospectus under the caption "Management of the
          Fund" is incorporated herein by reference. Neither State Farm
          Investment Management Corp., nor any of its directors or officers, has

                 AMENDED AND RESTATED ARTICLES OF INCORPORATION

<PAGE>
 
          (1) To engage generally in the business of investing, reinvesting,
owning, holding or trading in securities, as defined in the Investment Company

Investment Company Act as an open-end, management company.



          (2) To engage in any one or more businesses or transactions, or to
acquire all or any portion of any entity engaged in any one or more businesses
or transactions, which the Board of Directors may from time to time authorize or
approve, whether or not related to the business described elsewhere in this
Article or to any other business at the time or theretofore engaged in by the
Corporation.



     (b) The foregoing enumerated purposes and objects shall be in no way
limited or restricted by reference to, or inference from, the terms of any other
clause of this or any other Article of the Charter of the Corporation, and each
shall be regarded as independent; and they are intended to be and shall be
construed as powers as well as purposes and objects of the Corporation and shall
be in addition to and not in limitation of the general powers of corporations
under the General Laws of the State of Maryland.



     FOURTH:  The present address of the principal office of the Corporation in
this State is 11 East Chase Street, Baltimore, Maryland 21202.



     FIFTH:  The name and address of the resident agent of the Corporation in
this State are Prentice-Hall Corporation Systems Maryland, Inc., 11 East Chase

corporation.



     SIXTH:      (a) The total number of shares of capital stock which the
Corporation initially has authority to issue is 40,000,000 shares of capital
stock (par value $1.00 per share), amounting in aggregate par value to
$40,000,000.  All of such shares are classified as "Common Stock".



     (b) Unless otherwise prohibited by law, so long as the Corporation is
registered as an open-end company under the Investment Company Act, the Board of
Directors shall have the power and authority, without the approval of the
holders of any outstanding shares, to increase or decrease the number of shares
of capital stock that the Corporation has authority to issue.
<PAGE>
 
     (c) The following is a description of the preferences, conversion and other
rights, voting powers, restrictions, limitations as to dividends,
qualifications, and terms and conditions of redemption of the shares of Common
Stock:



          (1) Dividends and Distributions.  Dividends and capital gains
distributions on shares of Common Stock may be paid with such frequency, in such
form and in such amount as the Board of Directors may determine by resolution
adopted from time to time, or pursuant to a standing resolution or resolutions
adopted only once or with such frequency as the Board of Directors may
determine, after providing for actual and accrued liabilities.  All dividends
and distributions on shares of Common Stock shall be distributed pro rata to the
holders of Common Stock in proportion to the number of shares of Common Stock
held by such holders at the date and time of record established for the payment
of such dividends or distributions.



     Dividends and distributions may be paid in cash, property or additional
shares of Common Stock, or a combination thereof, as determined by the Board of
Directors or pursuant to any program that the Board of Directors may have in
effect at the time for the election by stockholders of the form in which
dividends or distributions are to be paid.  Any such dividend or distribution
paid in shares shall be paid at the current net asset value thereof.



          (2) Voting. On each matter submitted to a vote of the stockholders,
each holder of shares of Common Stock shall be entitled to one vote for each
share standing in his name on the books of the Corporation.



          (3) Redemption by Stockholders. Each holder of shares of Common Stock
shall have the right at such times as may be permitted by the Corporation to
require the Corporation to redeem all or any part of his shares of Common Stock,
at a redemption price per share equal to the net asset value per share of Common
Stock next determined after the shares are properly tendered for redemption,
less such redemption fee (not to exceed l% of the net asset value of the shares
redeemed), if any, as may be established by the Board of Directors in its sole
discretion. Payment of the redemption price shall be in cash; provided, however,
that the Corporation may, to the extent and in the manner permitted by the
Investment Company Act, make payment wholly or partly in securities or other
assets of the Corporation, at the value of such securities or assets used in
such determination of net asset value.



     Notwithstanding the foregoing, the Corporation may postpone payment of the
redemption price and may suspend the right of the holders of shares of Common
Stock to require the Corporation to redeem shares of Common Stock during any
period or at any time when and to the extent permissible under the Investment
Company Act.
<PAGE>
 
          (4) Net Asset Value Per Share. The net asset value per share of Common
Stock shall be the quotient obtained by dividing the value of the net assets of
the Corporation (being the value of the assets of the Corporation less the
liabilities of the Corporation) by the total number of shares of Common Stock
outstanding, all as determined by or under the direction of the Board of
Directors in accordance with generally accepted accounting principles and the
Investment Company Act. Subject to the applicable provisions of the Investment
Company Act, the Board of Directors, in its sole discretion, may prescribe and
set forth in the By-Laws of the Corporation or in a duly adopted resolution of
the Board of Directors such bases and times for determining the value of the
assets belonging to the Corporation and the net asset value per share of
outstanding shares of Common Stock, or the net income attributable to such
shares, as the Board of Directors deems necessary or desirable. The Board of
Directors shall have full discretion, to the extent not inconsistent with the
Maryland General Corporation Law and the Investment Company Act, to determine
which items shall be treated as income and which items as capital and whether
any item of expense shall be charged to income or capital. Each such
determination and allocation shall be conclusive.



     (d) The Corporation may issue and sell fractions of shares of Common Stock
having pro rata all the rights of full shares, including, without limitation,
the right to vote and to receive dividends, and wherever the words "share" or
"shares" are used in the Charter or By-Laws of the Corporation as amended from
time to time, they shall be deemed to include fractions of shares where the
context does not clearly indicate that only full shares are intended.



     (e) The Corporation shall not be obligated to issue certificates
representing shares of Common Stock.  At the time of issue or transfer of shares
without certificates, the Corporation shall provide the stockholder with such
information as may be required under the Maryland General Corporation Law.



     SEVENTH:  The number of directors of the Corporation shall be five, which
number may be increased or decreased pursuant to the By-Laws of the Corporation
as amended from time to time, but shall never be less than the minimum number
permitted by the General Laws of the State of Maryland now or hereafter in
force.  The names of the directors who are serving until the next annual meeting
and until their successors are elected and qualify are as follows:

               Edward B. Rust, Jr.
               Albert H. Hoopes
               Roger S. Joslin
               Davis U. Merwin
               James A. Shirk



     EIGHTH:  (a) The following provisions are hereby adopted for the purpose of
defining, limiting, and regulating the powers of the Corporation and of the
directors and stockholders:
<PAGE>
 
          (1) The Board of Directors is hereby empowered to authorize the
issuance from time to time of shares of its capital stock, whether now or
hereafter authorized, for such consideration as may be deemed advisable by the
Board of Directors and without any action by the stockholders.



          (2) No holder of any stock or any other securities of the Corporation,
whether now or hereafter authorized, shall have any preemptive right to
subscribe for or purchase any stock or any other securities of the Corporation
other than such, if any, as the Board of Directors, in its sole discretion, may
determine and at such price or prices and upon such other terms as the Board of
Directors, in its sole discretion, may fix.



          (3) Notwithstanding any provision of law requiring the authorization
of any action by a greater proportion than a majority of the total number of
shares of all classes of capital stock or of the total number of shares of any
class of capital stock, such action shall be valid and effective if authorized
by the affirmative vote of the holders of a majority of the total number of
shares of all classes outstanding and entitled to vote thereon, except as
otherwise provided in the Charter.



          (4) To the fullest extent permitted by Maryland statutory or
decisional law, as amended or interpreted, and the Investment Company Act, no
director or officer of the Corporation shall be personally liable to the
Corporation or its stockholders for money damages; provided, however, that
nothing herein shall be construed to protect any director or officer of the
Corporation against any liability to the Corporation or its security holders 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. No amendment of the Charter of the Corporation or repeal of any of
its provisions shall limit or eliminate the limitation of liability provided to
directors and officers hereunder with respect to any act or omission occurring
prior to such amendment or repeal.



          (5) The Corporation reserves the right from time to time to make any
amendments of its Charter which may now or hereafter be authorized by law,
including any amendments changing the terms or contract rights, as expressly set
forth in its Charter, of any of its outstanding stock by classification,
reclassification or otherwise.



     (b) The enumeration and definition of particular powers of the Board of
Directors included in the foregoing shall in no way be limited or restricted by
reference to or inference from the terms of any other clause of this or any
other Article of the Charter of the Corporation, or construed as or deemed by
inference or otherwise in any manner to exclude or limit any powers conferred
upon the Board of Directors under the General Laws of the State of Maryland now
or hereafter in force.
<PAGE>
 
     NINTH:    The duration of the Corporation shall be perpetual.



IN WITNESS WHEREOF, I have signed these Articles of Incorporation, acknowledging
the same to be my act, on November 8, 1976.

corporation will be served by such action.  The removal of an officer or agent
does not prejudice his contract rights, if any.  Any vacancy occurring in any
office of the corporation shall be filled by the board of directors.

the corporation.

in the event of the president's inability or refusal to act, the vice president
(or in the event there be more than one vice president, the vice presidents in

records.  The secretary shall give, or cause to be given, notice of all meetings
of the stockholders and meetings of the board of directors when notice thereof

to the same with his or her signature.  The secretary shall perform such other
duties as the board of directors may prescribe.

there be more than one, the assistant secretaries in the order determined by the
board of directors (or if there be no such determination, then in the order of

                                   ARTICLE VI
                                 CAPITAL STOCK

       Section 6.01.  Certificates of stock.  Every holder of stock in the
corporation shall be entitled, upon request, to have a certificate or
certificates, signed by, or in the name of the corporation by, the president or
a vice president and countersigned by the treasurer, an assistant treasurer, the
secretary or an assistant secretary of the corporation, certifying the number of
full shares owned by him in the corporation.  No certificates shall be issued
for fractional shares.  Where a certificate is countersigned by a transfer agent
other than the corporation or its employee, any other signature on the
certificate may be facsimile.  In case any officer or transfer agent who has
signed or whose facsimile signature has been placed upon a certificate shall
have ceased to be such officer or transfer agent before such certificate is
issued, it may be issued by the corporation with the same effect as if he were
such officer or transfer agent at the date of issue.



       Section 6.02.  Lost certificates.  The board of directors may direct a
new certificate or certificates be issued in place of any certificate or
certificates previously issued by the corporation which are alleged to be lost,
mutilated or destroyed, upon such terms and upon such conditions as the board of
directors may prescribe.



       Section 6.03.  Transfers of stock.  The shares of stock of the
corporation shall be transferable on the books of the corporation at the request
of the record holder thereof in person or by a duly authorized attorney, upon
presentation to the corporation or its transfer agent of a duly executed
assignment or authority to transfer, or proper evidence of succession, and, if
the shares are represented by a certificate, a duly endorsed certificate or
certificates of stock surrendered for cancellation, and with such proof of the
authenticity of the signatures as the corporation or its transfer agent may
reasonably require.  The transfer shall be recorded on the books of the
corporation, the old certificates, if any, shall be cancelled, and the new
record holder, upon request, shall be entitled to a new certificate or
certificates.
<PAGE>
 
       Section 6.04.  Fixing of record date.  The board of directors may fix in
advance a date as a record date for the determination of the stockholders
entitled to notice of or to vote at any meeting of stockholders or any
adjournment thereof, or to express consent to corporate action in writing
without a meeting, or to receive payment of any dividend or other distribution
or allotment of any rights, or to exercise any rights in respect of any change,
conversion or exchange of stock, or for the purpose of any other lawful action,
provided that such record date shall not be a date more than 90 days, and in the
case of a meeting of stockholders not less than 10 days, prior to the date on
which the particular action requiring such determination of stockholders is to
be taken.  In such case only such stockholders as shall be stockholders of
record on the record date so fixed shall be entitled to such notice of, and to
vote at, such meeting or adjournment, or to give such consent, or to receive
payment of such dividend or other distribution, or to receive such allotment of
rights, or to exercise such rights, or to take such other action, as the case
may be, notwithstanding any transfer of any shares on the books of the
corporation after any such record date.



       Section 6.05.  Registered stockholders.  The corporation shall be
entitled to treat the holder of record of shares as the holder in fact thereof
and, accordingly, shall not be bound to recognize any equitable or other claim
to or interest in such shares on the part of any other person, whether or not it
shall have express or other notice thereof, except as otherwise provided by
statute.



                                  ARTICLE VII
                                   CUSTODIAN

       Section 7.01.  Qualifications.  The corporation shall at all times
employ, pursuant to a written contract, one or more banks or trust companies,
each having an aggregate capital, surplus and undivided profits (as shown in its
last published report) of at least $2,000,000, as custodian to hold the funds
and securities of the corporation.



       Section 7.02.  Contract.  Such contract shall be upon such terms and
conditions and may provide for such compensation as the board of directors deems
necessary or appropriate, provided such contract shall further provide that the
custodian shall deliver securities owned by the corporation only upon sale of
such securities for the account of the corporation and receipt of payment
therefor by the custodian or when such securities may be called, redeemed,
retired or otherwise become payable.  Such limitation shall not, however,
prevent:



       (a)  the delivery of securities for examination to the broker selling the
same in accord with the "street delivery" custom whereby such securities are
delivered to such broker in exchange for a
<PAGE>
 
 delivery receipt exchanged on the
same day for an uncertified check of such broker to be presented on the same day
for certification;



       (b) the delivery of securities of an issuer in exchange for or conversion
into other securities alone or cash and other securities pursuant to any plan of
merger, consolidation, reorganization, recapitalization or readjustment of the
securities of such issuer;



       (c) the conversion by the custodian of securities owned by the
corporation pursuant to the provisions of such securities into other securities;



       (d) the surrender by the custodian of warrants, rights or similar
securities owned by the corporation in the exercise of such warrants, rights or
similar securities, or the surrender of interim receipts or temporary securities
for definitive securities;



       (e) the delivery of securities owned by the corporation as a redemption
in kind of securities issued by the corporation.



The custodian shall deliver funds of the corporation only upon the purchase of
securities for the portfolio of the corporation and the delivery of such
securities to the custodian, but such limitation shall not prevent the release
of funds by the custodian for redemption of shares issued by the corporation,
for payment of interest, dividend disbursements, taxes and management fees, for
payments in connection with the conversion, exchange or surrender of securities
owned by the corporation as set forth in sub-paragraphs (b), (c) and (d) above,
for operating expenses of the corporation and for any other purpose authorized
by the board of directors.



       Section 7.03.  Termination of contract.  The contract of employment of
the custodian shall be terminable by either party on 60 days' written notice to
the other party.  Upon any termination, the board of directors shall use its
best efforts to obtain a successor custodian, but lacking success in the
appointment of a successor custodian, the question of whether the corporation
shall be liquidated or shall function without a custodian shall be submitted to
the stockholders before delivery of any funds or securities of the corporation
to any person other than a successor custodian, including a temporary successor
selected by the retiring custodian.  If a successor custodian is found, the
retiring custodian shall deliver funds and securities owned by the corporation
directly to the successor custodian.
<PAGE>
 
       Section 7.04.  Agents of custodian.  The provisions of any other section
of these bylaws to the contrary notwithstanding, any contract of employment of a
custodian to hold the funds and securities of the corporation may authorize the
custodian, upon approval of the board of directors, to appoint other banks or
trust compan ies meeting the requirements of this article, domestic and foreign
(including domestic and foreign branches), to perform all or a part of the
duties of the custodian under its contract with the corporation.



       Section 7.05.  Negotiable instruments.    All checks and drafts for the
payment of money shall be signed in the name of the corporation by such officer
or officers or such other person or persons as the board of directors may
designate, and all requisitions or orders for the payment of money by the
custodian or for the issue of checks and drafts therefor, all promissory notes,
all assignments of shares or securities standing in the name of the corporation,
and all requisitions or orders for the assignment of shares or securities
standing in the name of the custodian or its nominee, or for the execution of
powers to transfer the same, shall be signed in the name of the corporation by
not less than two of its officers.  Promissory notes, checks or drafts payable
to the corporation may be endorsed only to the order of the custodian or its
agent.



                                  ARTICLE VIII
                    TRANSACTIONS WITH OFFICERS AND DIRECTORS

       Section 8.01.  Purchase and sale of securities.  The corporation shall
not purchase any securities (other than shares issued by the corporation) from,
or sell any securities (other than shares issued by the corporation and
securities paid in satisfaction of shares deposited for redemption during a
period during which the corporation is redeeming its shares principally in kind)
to, any director or officer of the corporation, or any director, officer or
partner of any firm which acts as investment adviser or principal underwriter
for the corporation acting as principal, except to the extent permitted to do so
under the Investment Company Act of 1940 or the rules or regulations thereunder
or by appropriate order or written advice of the Securities and Exchange
Commission.



       Section 8.02.  Concentration in any one issuer.  The corporation shall
not purchase or retain securities of a company if all of the directors and
officers of the corporation and of its investment adviser who individually own
beneficially more than 1/2% of the securities of the company collectively own
more than 5% of such securities.



       Section 8.03.  Transactions in shares of the corporation.  No director or
officer of the corporation or of its investment adviser shall take a long or
short position in the capital stock of the corporation, except that officers or
directors may purchase shares of the corporation for investment purposes at the
same price as that available to the public at the time of purchase.

                                   ARTICLE IX
                                INDEMNIFICATION

       Section 9.01.  Indemnification.  Each person who is or was a director or
officer of the corporation, and each person who serves or served at the request
of the corporation as a director or officer of another corporation (and their
respective heirs, executors and administrators), shall be indemnified by the
corporation in accordance with, and to the fullest extent authorized by, the
General Corporation Law of the State of Maryland as it may be in effect from
time to time, provided that (unless otherwise permitted by the Investment
Company Act of 1940, the rules and regulations thereunder or the Securities and
Exchange Commission):



       (a) this provision shall not protect any person against any liability to
the corporation or to its stockholders 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;



       (b) if there is neither a final court determination on the merits that
the person seeking indemnification is not liable nor a court determination that
he was not guilty of willful misfeasance, bad faith, gross negligence or
reckless disregard of the duties involved in the conduct of his office, no
indemnification shall be permitted unless a determination that the person was
not guilty of any such misconduct has been made by (i) the vote of a majority of
a quorum of directors who are neither "interested persons" of the corporation as
defined in section 2(a)(19) of the Investment Company Act of 1940 nor parties to
the proceedings ("disinterested, non-party directors") or (ii) an independent
legal counsel (not including a counsel who does work for either the corporation,
its investment adviser or principal underwriter, or any person affiliated with
any of these persons); and



       (c) before the final disposition of a proceeding, the corporation may pay
the expenses, including attorneys' fees, incurred by any such person in
defending a civil or criminal action, suit or proceeding, only if:



          (i) authorized in the specific case, by a majority of the
disinterested, non-party directors, or if there are no disinterested, non-party
directors, by the board of directors;
<PAGE>
 
       (ii) any advances are limited to amounts used, or to be used, for the
preparation and/or presentation of a defense to the action (including costs
connected with preparation of a settlement);



       (iii)  any advances are accompanied by a written promise by, or on behalf
of, the recipient to repay that amount of the advance which exceeds the amount
which it is ultimately determined that the recipient is entitled to receive from
the corporation by reason of indemnification;



       (iv) such promise is secured by (1) a surety bond or other security
provided by the recipient of the advance or (2) other suitable insurance, unless
a majority of a quorum of the disinterested, non-party directors, or an
independent legal counsel in a written opinion, has determined, based on a
review of readily available facts, that there is reason to believe that the
recipient of the advance ultimately will be found entitled to indemnification.



                                   ARTICLE X

                               GENERAL PROVISIONS

<PAGE>
 
            (ii)  the corporation's net income so determined for the current or
preceding fiscal year.

Exchange Commission may prescribe.

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

                      INVESTMENT ADVISORY AND MANAGEMENT
                               SERVICES AGREEMENT



          AGREEMENT dated October 1, 1978, by and between STATE FARM INTERIM
FUND, INC., a Maryland corporation registered under the Investment Company Act
of 1940 as an open-end diversified management investment company (hereinafter
called the "Fund"), and STATE FARM INVESTMENT MANAGEMENT CORP., a Delaware
corporation registered under the Investment Advisers Act of 1940 as an
investment adviser (hereinafter called the "Adviser"):



                                  WITNESSETH:

     In consideration of the mutual covenants hereinafter contained, it is
hereby agreed by and between the parties hereto as follows:



          1.  Engagement of Adviser.  The Fund hereby employs the Adviser to act
as investment adviser for and to manage the investment and reinvestment of the
assets of the Fund, and to administer its affairs to the extent requested by and
subject to the supervision and control of the Board of Directors of the Fund for
the period and upon the terms herein set forth.  The Adviser shall give due
consideration to the investment policies and restrictions and the other
statements concerning the Fund in the Fund's articles of incorporation, by-laws,
and registration statements under the Investment Company Act of 1940 (the "Act")
and the Securities Act of 1933 (the "Securities Act"), and to the provisions of
the Internal Revenue Code applicable to the Fund as a regulated investment
company.



          The Adviser is authorized to make the decisions to buy and sell
securities of the Fund, to place the Fund's portfolio transactions with
securities broker-dealers, and to negotiate brokerage commissions and other
terms of such transactions on behalf of the Fund.  The Adviser is authorized to
exercise discretion within the Fund's policy concerning allocation of its
portfolio brokerage as permitted by law, including but not limited to section
28(e) of the Securities Exchange Act of 1934, and in so doing shall not be
required to make any reduction in its investment advisory fees.



          The Adviser shall for all purposes herein provided be deemed to be an
independent contractor, and unless otherwise expressly provided or authorized
shall have no authority to act for or represent the Fund in any way or otherwise
be deemed an agent of the Fund.



          2. Expenses. The Adviser shall at its own expense furnish to the Fund
suitable office space in its own offices or in such other place as may be agreed
upon from time to time between the parties, hereto, and in addition shall
furnish all necessary office facilities, equipment, administrative services and
<PAGE>
 
clerical personnel for managing the affairs and investments of the Fund.  The
Adviser shall arrange, if desired by the Fund, for officers or employees of the
adviser to serve without salary from the Fund as directors, officers or agents
of the Fund if duly elected or appointed to such positions by the shareholders
of the Fund or by the Board of Directors thereof and subject to their individual
consent and to any limitations imposed by law.  The Adviser assumes and shall
pay all of the expenses of the Fund, other than those expressly to be paid by
the Fund as specified herein and expenses payable by any distributor of the
Fund's shares pursuant to a separate agreement between the Fund and such
distributor.



          The Fund assumes and shall pay the following expenses related to the
Fund: (i) all fees of the Adviser hereunder; (ii) all charges of independent
auditors, of legal counsel, of depositaries, custodians and other agencies for
the safekeeping and servicing of its cash, securities and other property, and
for keeping the Fund's books of account and calculating the Fund's net asset
value if such books are kept and such calculations are made by a custodian, and
of its transfer agents, registrars and dividend disbursing and redemption
agents, if any; (iii) all compensation of directors other than those affiliated
with the Adviser; (iv) interest, if any, on obligations incurred by the Fund;
(v) the cost of preparing, printing and distributing stock certificates,
corporate reports, notices, proxy solicitation material and reports to its
shareholders; (vi) all taxes and corporate fees payable to federal, state and
other governmental agencies, domestic or foreign; (vii) all registration and
filing fees payable under federal securities laws; and (viii) the cost of the
Fund's membership in any association of investment companies.  The Fund shall
also assume and pay the following expenses related to the Fund except to the
extent that they shall be assumed and paid by a distributor of the Fund's shares
pursuant to a separate agreement between the Fund and such distributor: (i) all
expenses of printing and distributing any prospectus of the Fund and of
preparing, printing, distributing and disseminating any other literature,
advertising and selling aids in connection with the offering of the shares for
sale (except the cost of preparing, printing and distributing reports and other
communications to shareholders in their capacity as such); (ii) all expenses of
advertising in connection with such offering; and (iii) all fees payable to
states in connection with the qualification of Fund shares for sale, or the
qualification of the Fund as a dealer or broker, under the laws of such states
as may be designated by the Underwriter.  In addition to the payment of
expenses, the Fund shall also assume and pay all brokers' commissions and other
charges incurred in connection with the purchase and sale of portfolio
securities.  The Fund shall not pay or incur any obligation for any management
or administrative expenses for which the Fund intends to seek reimbursement from
the Adviser as herein provided without first obtaining the written approval of
the Adviser.  The Fund shall be free to retain at its expense other persons to
furnish it with any services whatsoever, including, without limitation,
statistical, factual or technical information or advice.



          3.  Compensation of Adviser; limitation of Fund's expenses.  For the
services to be rendered, the facilities to be furnished and the expenses to be
assumed by the Adviser, as provided in this Agreement, the Fund shall pay to the
Adviser for each of the Fund's fiscal quarters a fee equal to one quarter of the
annual percentage of the average net assets of the fund during each such fiscal
quarter in accordance with the following schedule:
<PAGE>
 
            Annual Rate of Advisory Fee Based on Average Net Assets
            -------------------------------------------------------

                         .20% of the first $50 million
                          .15% of the next $50 million
                         .10% in excess of $100 million

Such payment to the Advisor shall be made within 20 days after the last day of
each of the Fund's fiscal quarters with a final adjustment as of the end of each
fiscal year so that the annual fee will equal appropriate annual percentages of
the average net assets of the Fund during the fiscal year.



          The Adviser shall reimburse the Fund to such extent as the total
expenses of the Fund for any fiscal year during the term of this agreement
chargeable to income on the accrual basis of accounting, including fees to the
Adviser but excluding all (i) taxes, (ii) interest and (iii) extraordinary
litigation expenses, shall exceed .4% of the average net assets to the Fund
during such year.  Brokers' commissions and other charges incurred in connection
with the purchase and sale of portfolio securities shall not be regarded as
expenses for this purpose.  Such reimbursement shall be made quarterly on an
interim basis, with a final adjustment as of the end of each year.



          For the quarter and year in which this agreement becomes effective or
terminates there shall be an appropriate proration of the fee and of the
reimbursement (if any) on the basis of the number of days that the agreement is
in effect during such quarter and year.



          For purposes of this section the average net asset value during a
period shall be determined on the basis of the net asset value of the Fund as of
the close of each business day during the period in accordance with the articles
of incorporation of the Fund. If pursuant to the articles of incorporation of
the Fund the net asset value is not required to be determined on any particular
business day, then for the purpose of the foregoing computations the net asset
value last determined shall be deemed to be the net asset value as of the close
of business on that day.



          4. Interested parties; services other than as Adviser. It is
understood that the officers, directors, agents and shareholders of the Fund are
or may be interested in the Adviser as officers, directors, agents, shareholders
or otherwise, and that the officers, directors, shareholders and agents of the
Adviser may be interested in the Fund otherwise than as a shareholder. It is
further understood that the Adviser, by virtue of separate agreements, may also
act as transfer agent, dividend disbursing agent and underwriter for the Fund
and that State Farm Mutual Automobile Insurance Company, by virtue of a separate
agreement, may furnish services to the Adviser to assist the Adviser in
fulfilling its obligations to the Fund pursuant to this agreement. The services
of the Adviser herein provided are not to be deemed exclusive and the Adviser
shall be free to render similar services or other services to others so long as
its services hereunder shall not be impaired thereby.
<PAGE>
 
          5. Limitation of liability of Adviser. The Adviser shall not be liable
for any error of judgment or import of law, or for any loss suffered by the Fund
or its shareholders from or as a consequence of any act or omission of the
Adviser, or of any of the directors, officers, employees or agents of the
Adviser, in connection with the matters to which this agreement relates, except
loss resulting from willful misfeasance, bad faith or gross negligence on the
part of the Adviser in the performance of its obligations and duties or by
reason of its reckless disregard of its obligations and duties under this
agreement.



          6. Term and termination. This agreement shall become effective on the
date hereof and, unless sooner terminated as hereinafter provided, shall
continue in effect until December 1, 1979, and from year to year thereafter, but
only so long as such continuance is specifically approved at least annually in
the manner required by the Act.



          This agreement may be terminated at any time without the payment of
any penalty by the Board of Directors of the Fund, or by vote of the holders of
a majority of the outstanding shares of the Fund, or by the Adviser, on sixty
(60) days' written notice to the other party.



          This agreement may be terminated at any time without the payment of
any penalty by vote of the Board of Directors of the Fund in the event that it
shall have been established by a court of competent jurisdiction that the
Adviser or any officer or director of the Adviser has taken any action which
results in a breach of the covenants of the Adviser set forth herein.



          This agreement shall automatically terminate in the event of its
assignment (as defined in the Act).



          7.  Notices.  Any notice under this agreement shall be in writing,
addressed and delivered or mailed, postage prepaid, to the other party at such
address as such other party may designate for the receipt of such notice.



          8.  "State Farm" name.  The Fund agrees that upon the termination of
this agreement at any time or for any reason it shall, when so requested by the
Adviser, eliminate all reference to the name "State Farm" from its corporate
name and thereafter refrain from using the name "State Farm" in connection with
its business or activities in any form or combination whatsoever except as may
be necessary to identify its prior name.
<PAGE>
 
          9. Amendment. This agreement may be amended only with the affirmative
vote (i) of a majority of those directors who are not "interested persons" (as
defined in the Act) of the Fund or the Advisor, voting in person at a meeting
called for the purpose of voting on such approval, and (ii) of the holders of a
majority of the outstanding shares of the Fund.



          IN WITNESS WHEREOF, the Fund and the Adviser have caused this
agreement to be executed in their names and on their behalf by and through their
duly authorized officers all on the day and year first above written.

                               SERVICE AGREEMENT
                         (As amended September 9, 1977)



          STATE FARM MUTUAL AUTOMOBILE INSURANCE COMPANY, an Illinois
corporation (Auto Company), STATE FARM INVESTMENT MANAGEMENT CORP., a Delaware
corporation and a wholly-owned second-tier subsidiary of Auto Company (Manager),
and STATE FARM INTERIM FUND, INC., a Maryland corporation and an open-end
diversified management investment company registered under the Investment
Company Act of 1940 (Fund) to which Manager is investment adviser under an
Investment Advisory and Management Services Agreement dated December 21, 1976
and amended September 9, 1977 agree that:



          1.  Manager shall have the right to use, and Auto Company shall make
available for the use of Manager, (i) such part-time services of employees of
Auto Company engaged in its investment operations, and such services of
administrative and other employees of Auto Company, for periods to be agreed
upon by Manager and Auto Company, and (ii) such administrative, clerical,
stenographic and other support services and office supplies and equipment, as
may in each case be reasonably required by Manager in the performance of its
obligations as investment adviser to the Fund under their Investment Advisory
and Management Services Agreement and any agreements amending or superseding
such agreement.



          2. Manager shall have the right to use, and Auto Company shall furnish
for the use of Manager such office space as is reasonably needed by Manager in
the performance of its obligations as investment adviser to the Fund.



          3.  In performing services for Manager under this agreement, the
employees of Auto Company may, to the full extent that they deem appropriate,
have access to and utilize statistical and economic data, investment research
and reports and other information prepared for or contained in the files of the
Auto Company which are relevant to making investment decisions within the
investment objectives of the Fund, and may make such information available to
Manager; provided, that any such information prepared or obtained in connection
with a private placement or other nonpublic transaction need not be made
available to Manager if Auto Company deems such information confidential.



          4.  Employees of Auto Company performing services for Manager pursuant
hereto shall report and be responsible solely to the officers and directors of
Manager or persons designated by them.  Auto Company shall have no
responsibility for investment recommendations and decisions of Manager based
upon information or advice given or obtained by or through such Auto Company
employees; provided, however, that the foregoing shall not be construed to
relieve Auto Company of any liability to the Fund or its security holders to
which the Auto Company would otherwise be subject by reason of its willful
misfeasance, bad faith or gross negligence, in the performance of its duties
hereunder, or by reason of its reckless disregard of its obligations and duties
hereunder.
<PAGE>
 
          5.  The obligation of performance of the Investment Advisory and
Management Services Agreement of Manager with the Fund is solely that of
Manager, for which Auto Company assumes no responsibility except as otherwise

          6.  In consideration of the services to be rendered and the facilities
to be provided to Manager by Auto Company and its employees pursuant to this
agreement, Manager agrees to reimburse Auto Company for such costs, direct and
indirect, as may be fairly attributable to the services performed and the
facilities provided for Manager.  Such costs shall include, but shall not be
limited to, an appropriate portion of salaries, employee benefits, general
overhead expense, and supplies and equipment, and a charge in the nature of rent
for the cost of space in the Auto Company offices fairly allocable to activities
of Manager under its Investment Advisory and Management Services Agreement with
the Fund.  In the event of disagreement between Manager and Auto Company, as to
a fair basis for allocating or apportioning costs, such basis shall be fixed by
the independent public accountants for the Fund.



          7.  This agreement shall become effective on the date hereof and shall
continue in effect until December 1, 1978, and thereafter shall continue in
effect from year to year if its continuance is specifically approved by (i) the
vote of a majority of the outstanding voting securities of the Fund (as defined
in section 2(a)(42) of the Investment Company Act of 1940 ("Act")), or (ii) the
vote of a majority of the Board of Directors of the Fund, and in either case by
a majority of the Directors of the Fund who are not parties to the agreement or
interested persons (as defined in section 2(a)(19) of the Act) of the Fund, Auto
Company or Manager, voting in person at a meeting called for such purpose;
provided, however, that this agreement (a) may be terminated at any time,
without the payment of any penalty, either by the Board of Directors of the Fund
or by vote of a majority of the outstanding voting securities of the Fund, on
sixty days' written notice to Manager and to Auto Company, (b) shall terminate
automatically in the event of its assignment (as defined in section 2(a)(4) of
the Act), and (c) may be terminated by Manager or by Auto Company on sixty days'
written notice to each other and to the Fund.



          8.  This agreement may be amended at any time by mutual consent of the
parties, provided that such amendment shall not become effective until it has
been approved by vote of a majority of the outstanding voting securities of the
Fund.



          9.  Any notice under this agreement shall be in writing, addressed and
delivered or mailed postage prepaid to the other parties, at such addresses as
such other parties may designate for the receipt of such notices.  Until further
notice to the other parties, it is agreed that the address of Auto Company, that
of Manager and that of the Fund for this purpose shall be One State Farm Plaza,

                            UNDERWRITING AGREEMENT
                         (As amended September 9, 1977)



          AGREEMENT made this 21st day of December, 1976 and amended September
9, 1977, between STATE FARM INTERIM FUND, INC., a Maryland Corporation
(hereinafter called the "Fund"), and STATE FARM INVESTMENT MANAGEMENT CORP., a
Delaware corporation (hereinafter called the "Underwriter"):



                                  WITNESSETH:

          In consideration of the mutual covenants hereinafter contained, it is
hereby agreed by and between the parties hereto as follows:



          1. Appointment of Underwriter. The Underwriter is hereby appointed the
Fund's agent for the distribution of shares of common stock of the Fund.



          2. Undertaking of Underwriter. The Underwriter agrees to use its best
efforts to sell shares of the Fund at prices and on terms as hereinafter
provided, all subject to applicable federal and state laws and regulations and
to the Articles of Incorporation of the Fund, and subject also to such
limitations on the class of investors to whom shares may be offered as may be
described from time to time in the Fund's prospectus currently effective
("Prospectus") under the Securities Act of 1933 ("Securities Act"). The
Underwriter may in its discretion refuse to sell shares to any particular
applicant, and the Fund may similarly refuse to sell shares to any person. The
Underwriter or its agent shall be entitled to rely upon the certification of any
purchaser that he is a member of that class of investors to whom shares may be
offered as may be described from time to time in the Prospectus.



          3.  Appointment of dealers.  The Underwriter, as agent of the Fund,
shall sell shares of the Fund directly or to or through qualified dealers or
others in such manner (not inconsistent with the provisions hereof and the then
effective registration statement of the Fund under the Securities Act
("Registration Statement")) as the Underwriter may determine from time to time,
provided that no dealer or other person shall be appointed or authorized to act
as agent of the Fund without the prior written consent of the Fund and that the
form of each agreement between the Underwriter and any such dealer or other
person shall have been approved by the Fund.



          4.  Sales price of shares.  All shares of the Fund offered for sale or
sold by the Underwriter shall be so offered or sold at a price per share
determined in accordance with the Prospectus except as departure from such
prices may be permitted by the rules and regulations of the Securities and
Exchange
<PAGE>
 
Commission; provided however, that any public offering price for shares of the
Fund shall be the net asset value per share (computed in accordance with the
Articles of Incorporation of the Fund) next determined after the order for such
shares is placed with the Underwriter, to which there may be added a
distribution charge of not more than 9% of the public offering price.



          5.  Commissions and concessions.  The price the Fund shall receive for
all shares purchased from the Fund shall be the net asset value used in
determining the public offering price applicable to the sale of such shares.
The excess, if any, of the sales price over the net asset value of the shares
sold by the Underwriter as agent shall be retained by the Underwriter as a
commission for its services hereunder.  Out of such commission the Underwriter
may allow commissions or concessions to dealers and may allow them to others in
its discretion in such amounts as the Underwriter shall determine from time to
time.  Except as may be otherwise determined by the Underwriter and the Fund
from time to time, such commissions or concessions shall be uniform to all
dealers.



          6. Confirmations. The Underwriter shall issue and deliver on behalf of
the Fund such confirmations of sales made by it pursuant to this agreement as
may be required. At or prior to the time of delivery by the Fund to or on the
order of the Underwriter of certificates for any shares of common stock of the
Fund, the Underwriter will pay or cause to be paid to the Fund the amount due
the Fund for the sale of such shares. Certificates shall be issued or shares
registered on the transfer books of the Fund in such names and denominations as
the Underwriter may specify.



          7. Blue sky qualification; dealer registration. The Fund will execute
any and all documents and furnish any and all information which may be
reasonably necessary in connection with the qualification of its shares for sale
(including the qualification of the Fund as a dealer where necessary or
advisable) in such states as the Underwriter may reasonably request (it being
understood that the Fund shall not be required without its consent to qualify to
do business in any jurisdiction or to comply with any requirement which in its
opinion is unduly burdensome).



          8.  Sales material.  All sales material used or distributed by the
Underwriter or its dealers or others will conform to applicable laws and
regulations, and the Underwriter will furnish the Fund with copies of all such
material.



          9.  Repurchase of shares.  The Underwriter, as agent of and for the
account of the Fund, may repurchase shares of common stock of the Fund at such
prices and upon such terms and conditions as shall be specified in the
Prospectus.
<PAGE>
 
          10. Indemnification. The Underwriter will indemnify and save harmless
the Fund from any damage or expense on account of any wrongful act by the
Underwriter or any employee, representative or agent of the Underwriter.



          11. Conformity to Registration Statement. The Underwriter will require
each dealer to conform to the provisions hereof and of the Registration
Statement and Prospectus and neither the Underwriter nor any such dealer shall
withhold the placing of purchase orders so as to make a profit thereby.



          12.  Expenses.  The Fund will pay or cause to be paid (i) all expenses
(including the fees and disbursements of its legal counsel and independent
auditors, but not including printing expenses) related to the registration of
shares of its common stock under the Securities Act and (ii) all expenses
incident to the issuance of such shares (such as the cost of stock certificates,
issue taxes and fees of the transfer agent).  The Underwriter will pay all
expenses (other than expenses which one or more dealers may bear pursuant to any
agreement with the Underwriter) incident to the offering, sale and distribution
of the shares offered hereunder, including, without limiting the generality of
the foregoing, (i) all expenses of printing and distributing any prospectus of
the Fund and of preparing, printing, distributing and disseminating any other
literature, advertising and selling aids in connection with the offering of the
shares for sale (except the cost of preparing, printing and distributing reports
and other communications to shareowners in their capacity as such), (ii) all
expenses of advertising in connection with such offering, (iii) all fees payable
to states in connection with the qualification of Fund shares for sale and (iv)
all fees payable under state and federal laws in connection with the
qualification of the Fund or the Underwriter as a dealer, broker or agent.



          13. Term and termination. This agreement shall become effective on the
date hereof, and, unless sooner terminated as hereinafter provided shall
continue in effect until December 1, 1978 and from year to year thereafter, but
only so long as such continuance is specifically approved at least annually in
the manner required by the Investment Company Act of 1940. Either party hereto
may terminate this agreement at any time by giving the other party at least
sixty days' prior written notice of such termination specifying the date fixed
therefor. This agreement shall automatically terminate in the event of its
assignment (as defined in the Investment Company Act of 1940).



          14.  Notices.  Any notice under this agreement shall be in writing,
addressed and delivered or mailed, postage prepaid, to the other party at such
address as such other party may designate for the receipt of such notice.



          IN WITNESS WHEREOF, the Fund and the Underwriter have caused this
agreement to be executed in their names and on their behalf by and through their
duly authorized officers all on the day and year first above written.

                      DOMESTIC CORPORATE CUSTODY AGREEMENT
                      ------------------------------------


     AGREEMENT dated as of Nov 1, 1990 between MORGAN GUARANTY TRUST COMPANY of
New York, a New York banking corporation (the "Bank"), and STATE FARM INTERIM
FUND, INC. (the "Client").



     WHEREAS, the Client, which is a Maryland Corporation and an investment
company registered as such under the Investment Company Act of 1940, desires to
arrange for the custody of certain of its assets by the Bank and by certain
depositories located in the United States;



     WHEREAS, the Client specifically approves the designation by the Bank of
its New York Office as the office through which the Bank will perform many of
the services and fulfill many of its obligations under this Agreement;



     NOW THEREFORE, in consideration of the mutual agreement made herein, the
Bank and the Client agree as follows:



     1.   The Bank agrees to establish and maintain (a) one or more separate
custody accounts (singly a "Custody Account" and collectively the "Custody
Accounts") for any and all stocks, bonds and other securities (the "Securities")
from time to time received for the account of the Client by the Bank or a
Domestic Subcustodian and (b) one or more separate deposit accounts (singly a
"Deposit Account" and collectively the "Deposit Accounts") for any and all cash
(the "Cash") received for the account of the Client by the Bank.  The term
"Domestic Subcustodian" means a depository located in the United States
including, but not limited to, the Depository Trust Company, the Federal Reserve
Bank of New York and the Participants Trust Company, the use of which has been
expressly authorized by the Client.



     2.   Securities and Cash are permitted to be held by

     a)  the Bank; and

     b)  Domestic Subcustodians.
<PAGE>

     3. (a) The records maintained by the Bank of the Custody Accounts and the
Deposit Accounts will reflect all Securities and Cash maintained in accordance
with Section 1 hereof.

     (b) The Bank will require each Domestic Subcustodian holding Securities to
identify Securities held by it as being held for the account of the Bank for its
clients.

     (c) The Bank shall physically segregate any Securities which are physically
held by it; in all other respects the Securities may be commingled with other
securities no matter by whom owned, except for securities owned by the Bank as
principal, subject to the record-keeping requirements of subsection (b) above.
Securities may be held in certificated and uncertificated form.

     (d) Any Securities or Cash held by a Domestic Subcustodian will be subject
only to the instructions of the Bank acting in its capacity as agent of the
Client.

     (e) The Bank will authorize or permit the holding of Securities and Cash by
a Domestic Subcustodian only as long as (i) the Securities are not subject to
any right, charge, security interest, lien or claim of any kind in favor of such
Domestic Subcustodian or its creditors, including a receiver or trustee in
bankruptcy, except for a claim of payment for the safe custody or administration
of the Securities and (ii) beneficial ownership of the Securities is freely
transferable without the payment of money or value other than for safe custody
or administration of the Securities.

     (f) The Bank will allow independent public accountants of the Client
reasonable access to the records of the Bank relating to the Securities and Cash
as is required by those accountants in connection with their examination of the
books and records pertaining to the affairs of the Client.  Upon request, the
Bank will provide the Client with any reports obtained by the Bank on a Domestic
Subcustodian's accounting system, internal accounting controls and procedures
for safekeeping securities.



     4. The Bank shall make payments of Cash only:

     (a) upon the purchase of Securities for the Client and against the delivery
of Securities to the Bank, or the crediting of such Securities to the account of
the Bank or its Domestic Subcustodian for the account of the Client; provided,
however that such payment is made in the amount specified by Authorized
Instructions;

     (b) for any payments to be made in connection with the sale, conversion,
exchange or surrender of any Securities,

     (c) for purchase or redemption of shares of the Client upon delivery
thereof;

     (d) for payment of interest, dividends, taxes, management or supervisory
fees, and operating expenses;
<PAGE>
 
                                                                       JP MORGAN


     (e) for other purposes of the Client, but only upon receipt of, in addition
to Authorized Instructions, a certified copy of a resolution of the Board of
Directors or of the Executive Committee of the Client signed by an officer of
the Client and certified by its Secretary or an Assistant Secretary, specifying
the amount of such payment, setting forth the purpose for which such payment is
to be made, declaring such purpose to be a proper purpose, and naming the person

Agreement.

therefor in accordance with Authorized Instructions; provided that the Bank may
accept payment in such form as shall be satisfactory to it, and may deliver such
Securities and arrange for payment subsequent to delivery therefor in accordance

Dear Sirs:

     We have served as counsel for State Farm Interim Fund, Inc., a Maryland
corporation (Fund), in connection with the registration under the Securities Act
of 1933 (Act) of an indefinite number of shares of the Fund's capital stock, $1
par value per share (shares), pursuant to the Fund's registration statement,
no. 2-58160, on form N-1A (the registration statement).  In this connection, we
have examined originals, or copies certified or otherwise identified to our
satisfaction, of such documents, corporate and other records, certificates and
other papers as we deemed it necessary to examine for the purpose of this
opinion, including the charter and bylaws of the Fund, resolutions of the board
of directors authorizing the issuance of the shares, the form of certificates to
evidence the shares, and the registration statement.

     Based upon the above examination, it is our opinion that:

          1.  The Fund is a corporation duly organized and legally existing in
     good standing under the law of Maryland.

          2.  Upon issuance and delivery of the shares in accordance with the
     charter of the Fund and the resolutions of the Fund's board of directors
     authorizing the issuance of its shares, and the receipt by the Fund of a
     purchase price of not less than the net asset value or the par value per
     share, the shares will be legally issued and outstanding, fully paid and
     nonassessable.

shares authorized to be issued by the Fund's charter.

     We consent to the filing of this opinion as an exhibit to the registration
statement.  In giving this consent we do not admit that we are in the category
of persons whose consent is required under section 7 of the Act.

SECTION IV PAYMENT OF BENEFITS

4.1  DISTRIBUTIONS. The entire interest of the Participant in the Custodial
     Account must be, or commence to be, distributed not later than the
     Participant's Required Beginning Date. Not later than such time, the
     Participant may elect, on a form and at such time as may be acceptable to
     the Custodian, to have the balance in the Custodial Account distributed:

     (A)  In a single sum payment in Shares or cash (consisting of the entire
          balance or a portion of the balance in the Custodial Account with
          further distributions to be made pursuant to options B or C of this
          paragraph 4.1) to be paid not later than the Participant's Required
          Beginning Date;
<PAGE>
 
     (B)  In substantially equal annual or more frequent installments commencing
          not later than the Participant's Required Beginning Date and
          continuing over a period not to exceed the life expectancy of the
          Participant (if payments are to be made solely to the Participant) or
          life expectancy of such Participant and a beneficiary (if payments are
          to be made to the Participant while living and upon the Participant's
          death any remaining payments are to be made to the surviving
          beneficiary); or

     (C)  By purchase from an insurance company and delivery of an immediate or
          deferred annuity contract for the life of the Participant, or if the
          Participant so elects, for the lives of the Participant and a
          beneficiary (and the survivor thereof); provided, however, such
          contract must commence payments not later than the Participant's
          Required Beginning Date. The annuity contract must be selected by
          Participant and must satisfy the requirements of sections 408(b) (1),
          (2), (3) and (4) of the Internal Revenue Code.

     Except for payment of a life annuity, the life expectancy of the
     Participant and the Participant's spouse shall be redetermined annually.
     Life expectancy and joint and last survivor expectancy are computed by use
     of the return multiples contained in Tables V and VI of section 1.72-9 of
     the Income Tax Regulations.

     Even though distributions may have commenced pursuant to one of the above
     options, the Participant may, at any time, request a distribution of part
     or all of the balance in his/her Custodial Account or request the
     distribution method be changed to another option allowed by this paragraph
     4.1, subject to the minimum distribution requirements of paragraph 4.2. The
     request shall be made to the Custodian in writing and in a form acceptable
     to the Custodian.

4.2  MINIMUM DISTRIBUTIONS. If payments are made under option B of paragraph
     4.1, payments made in calendar years beginning with the year in which the
     Participant reaches age 70 1/2 shall be subject to the following:

     (i)   The minimum annual payment shall be calculated by dividing the
           Participant's entire interest in the Custodial Account at the
           beginning of each year by the lesser of (1) the applicable life
           expectancy or (2) if the Participant's spouse is not the Beneficiary,
           the applicable divisor determined from the table set forth in Q&A-4
           or Q&A-5, as applicable, of section 1.401 (a) (9)-2 of the Proposed
           Income Tax Regulations. Distributions after the death of the
           Participant shall be distributed using the applicable life expectancy
           as the relevant divisor without regard to proposed regulations
           section 1.401 (a) (9)-2. For purposes of this section, the life
           expectancy of the Participant and the Participant's spouse shall be
           redetermined annually.

     (ii)  The minimum monthly payment shall be calculated by dividing the
           result in (i) above by 12.

     (iii) The minimum quarterly payment shall be calculated by dividing the
           result in (i) above by 4.

     For the year in which the Participant attains age 70 1/2, the minimum
     distribution must be made by April 1 of the following calendar year. For
     all years following the year in which the Participant attains age 70 1/2,
     the minimum distribution must be made by December 31 of such years.

     Notwithstanding any provision of this agreement to the contrary, the
     distribution of a Participant's or Beneficiary's interest shall be made in
     accordance with the minimum distribution requirements of section 408(a)(6)
     or 408(b)(3) of the Internal Revenue Code and the regulations thereunder,
     including the incidental death benefit provisions of section 1.401(a)(9)-2
     of the proposed regulations, all of which are herein incorporated by
     reference.

     Furthermore, a Participant or Beneficiary may satisfy the minimum
     distribution requirements under sections 408(a)(6) and 408(b)(3) of the
     Internal Revenue Code by receiving a distribution from one IRA that is
     equal to the amount required to satisfy the minimum distribution
     requirements for two or more IRAs. For this purpose, the owner of two or
     more IRAs may use the alternative method described in Notice 88-38, 1988-1
     C.B. 524, to satisfy the minimum distribution requirements described above.

4.3  FAILURE TO ELECT OPTION. If the Participant fails to elect one of the
     described methods of distribution on or before April 1 of the calendar year
     following the calendar year in which the Participant attains age 70 1/2,
     distribution to the Participant will be made not later than that time by a
     single sum payment in cash or Shares at the sole discretion of the
     Custodian; provided, however, that the Custodian shall have no liability to
     the Participant for any tax penalty or other damages resulting from any
     inadvertent failure by the Custodian to make such distribution.

4.4  PREMATURE DISTRIBUTIONS. Before any distribution is made from the Custodial
     Account, except in the case of the Participant's death or disability (as
     defined in section 72(m) (7) of the Internal Revenue Code) or attainment of
     age 59 1/2, the Participant must furnish the Custodian with a declaration
     of his intentions as to the disposition of the amount to be distributed;
     however, the Custodian assumes no responsibility for the tax treatment of
     any distribution from the Custodial Account; such responsibility is solely
     that of the Participant ordering the distribution.

4.5  WITHDRAWAL OF EXCESS CONTRIBUTIONS. The Participant may elect to withdraw
     any excess contributions (as described in section 408(d)(4) of the Internal
     Revenue Code) made to the Custodial Account and, if withdrawn pursuant to
     section 408(d)(4) of the Internal Revenue Code, the net income attributable
     thereto. Participant must furnish Custodian a written notice (in a manner
     acceptable to Custodian) of his/her election to make such a withdrawal.

4.6  DISTRIBUTION ON DEATH.

     1.  Beneficiary Designated

         (a)  If the Participant dies on or after his/her Required Beginning
              Date and if distribution of his/her interest had previously
              commenced in accordance with Option B in paragraph 4.1, any
              remaining portion of such interest, at the election of the
              Beneficiary in accordance with procedures established by the
              Custodian, may be distributed either --

                   (i)  in an immediate single sum payment, or
                  (ii)  in installments paid at least as rapidly as under the
                        method of distribution being used as of the date of the
                        Participant's death.
<PAGE>
 
         (b)  If the Participant dies before reaching his/her Required Beginning
              Date and any portion of the Participant's interest is payable to
              or for the benefit of a Beneficiary, such portion, at the election
              of the Beneficiary in accordance with procedures established by
              the Custodian, may be distributed either -

                   (i)  in a single sum payment, made not later than December 31
                        of the year following the year of the Participant's
                        death,

                  (ii)  in installments commencing not later than December 31 of
                        the year following the year of the Participant's death,
                        and paid over a period not extending beyond the life
                        expectancy of such Beneficiary; provided, the
                        Beneficiary may accelerate such payments at any time, or

                 (iii)  if the Beneficiary is the Participant's surviving
                        spouse, in a single sum or installments, commencing by
                        the later of 1) December 31 of the year following the
                        year of the Participant's death, and 2) December 31 of
                        the calendar year in which the Participant would have
                        attained age 70-1/2, and paid over a period not
                        exceeding the life expectancy of such spouse
                        Beneficiary. The surviving spouse may change the
                        frequency or amount of such payments, subject to the
                        limit of the preceding sentence.


         (c)  If the Beneficiary is the Participant's surviving spouse, the
              spouse may, in lieu of the above distribution options in (a) and
              (b), elect to treat the Participant's account as his/her own
              individual retirement arrangement (IRA). This election will be
              deemed to have been made if such surviving spouse makes a regular
              IRA contribution to the account, makes a rollover contribution to
              the account, or fails to elect any of the above distribution
              options.

     For purposes of the above, payments will be calculated by use of the return
     multiples specified in Tables V and VI of section 1.72-9 of the Income Tax
     Regulations. Life expectancy of a surviving spouse shall be recalculated
     annually. In the case of any other designated beneficiary, life expectancy
     will be calculated at the time payment first commences and payments for any
     twelve-consecutive month period will be based on such life expectancy minus
     the number of whole years passed since distribution first commenced.

     For purposes of this requirement, any amount paid to a child of the
     Participant will be treated as if it has been paid to the surviving spouse
     if the remainder of the interest becomes payable to the surviving spouse
     when the child reaches the age of majority.

     2.  No Designated Beneficiary

         (a)  If the Participant dies on or after his/her Required Beginning
              Date and if distribution of his/her interest has commenced in
              accordance with option B in paragraph 4.1, and no Beneficiary has
              been designated or the designated Beneficiary and all secondary
              Beneficiaries have either predeceased the Participant or cannot
              after diligent effort, be found, the remaining portion of such
              interest, at the election of the recipient in accordance with
              procedures established by the Custodian, may be distributed -

                   (i)  in an immediate single sum payment, or

                  (ii)  in installments paid at least as rapidly as under the
                        method of distribution being used as of the date of the
                        Participant's death; provided that the entire remaining
                        interest must be distributed by December 31 of the
                        calendar year containing the fifth anniversary of the
                        Participant's death.

         (b)  If the Participant dies before reaching his/her Required Beginning
              Date and no Beneficiary has been designated, or the designated
              Beneficiary and all secondary Beneficiaries have predeceased the
              Participant or cannot, after diligent effort, be found, the entire
              interest of the Participant shall be distributed not later than
              December 31 of the calendar year containing the fifth anniversary
              of the Participants' death. In accordance with procedures
              established by the Custodian, the recipient of the distribution
              may elect to receive the distribution -

                   (i)  in a single sum payment, or

                  (ii)  in installment payments for a period not extending
                        beyond December 31 of the calendar year containing the
                        fifth anniversary of the Participant's death.

     3.  Failure to Elect Option.

         If any Beneficiary (other than a surviving spouse Beneficiary) under
         subparagraph (1) above or any recipient under subparagraph (2) above
         has the right to elect a method of distribution described in the
         respective subparagraphs and fails to do so within the time allowed by
         law, the Custodian has the right to make a single sum distribution at
         such time in cash or Shares; provided however, that the Custodian shall
         have no liability to any Beneficiary or recipient for any tax penalty
         or other damages resulting from any inadvertent failure by the
         Custodian to make such distribution.

4.7  DESIGNATION OF BENEFICIARY. A Participant shall have the right by written
     notice to the Custodian to designate, or to change, his/her Beneficiary to
     receive any amount to which Participant may be entitled in the event of
     his/her death before the complete distribution of such benefits. Such
     designation shall be on the Designation of Beneficiary Form or on a form
     permitted by the Custodian and shall be effective only when filed with, and
     acknowledged by, the Custodian before the death of the Participant. Such
     designation may include secondary Beneficiaries. If no such designation is
     in effect on the Participant's death, or if the designated Beneficiary and
     all secondary Beneficiaries have predeceased the Participant, his/her
     Custodial Account shall be distributed to his/her estate. Unless the
     Participant (in writing filed with the Custodian) makes an election
     described in subparagraph 4.6 (1) (a), the Beneficiary may elect one of the
     methods of distribution of benefits under paragraph 4.6. Such election
     shall be made in accordance with procedures established by the Custodian.
     If the Beneficiary fails, or is unable, to elect a method of payment, the
     Beneficiary's interest shall be distributed to him/her in cash in a single
     sum. The Custodian shall be responsible for determining the identity of the
     person or persons who qualify as the Beneficiary or Beneficiaries
     designated by a Participant pursuant to the terms 
<PAGE>
 
     of this paragraph 4.7, or who qualify as the executor or administrator of
     such Participant's estate in the case of a distribution required hereunder
     to be made to such Participant's estate. If any person to whom all or a
     portion of the Participant's interest is payable is a minor, payment of
     such minor's interest shall be made on behalf of such minor to the person
     designated by the Participant in the Designation of Beneficiary Form to
     receive such minor's interest as a custodian under the Illinois Uniform
     Gifts to Minors Act or similar statute. If any person to whom all or a
     portion of the Participant's interest is payable is a minor and if the
     Participant has not so designated a person to receive the minor's interest
     on behalf of such minor, the Custodian may in its sole discretion:

      (i)  distribute the interest to the legal guardian of such minor; or

     (ii)  designate an adult member of the minor's family, a guardian or a
           trust company (including the Custodian), as those terms are defined
           in the Illinois Uniform Gifts to Minors Act, as custodian for such
           minor under the Illinois Uniform Gifts to Minors Act or similar
           statute and distribute such minor's interest to the person so
           designated.

     The receipt by the guardian or the person designated as custodian under the
     Illinois Uniform Gifts to Minors Act or similar statute shall be a full
     discharge of the Custodian.

4.8  PAYMENT ON DISABILITY. If a Participant becomes disabled (as defined in
     section 72(m)(7) of the Internal Revenue Code), the amount credited to his
     account may be distributed to him in accordance with paragraph 4.1. Before
     making any distribution, however, the Custodian shall be furnished with
     proof of such disability.

SECTION V ROLLOVER CONTRIBUTIONS

5.1  Regular Rollover Contribution means a rollover contribution to this Plan
     from an eligible retirement plan as defined in section 402(a)(5) of the
     Internal Revenue Code other than a Special Rollover Contribution. A
     Participant who satisfies the eligibility requirements of Section II may
     make a regular Rollover Contribution in any amount in cash or Shares. The
     Participant shall execute such forms as the Custodian may require
     describing the source of the rollover contribution.

5.2  Special Rollover Contribution means (i) a rollover contribution to this
     Plan in a manner described in sections 402(c), 403(a)(4) or 403(b)(8) of
     the Internal Revenue Code, or (ii) a rollover contribution to this Plan
     from an Individual Retirement Account as defined in section 408(a) of the
     Internal Revenue Code and the amount rolled over was previously rolled over
     as described in sections 402(c), 403(a)(4) or 403(b)(8) of the Internal
     Revenue Code. A person who satisfies the eligibility requirements of
     Section II may adopt the Plan for the sole purpose of making a Special
     Rollover Contribution. The Custodian shall accept the Special Rollover
     Contribution in any amount in cash or Shares and establish a Custodial
     Account for the Participant, provided, however, that the Custodial Account
     shall consist only of the Special Rollover Contribution and the earnings
     thereon. The Participant shall execute such forms as the Custodian may
     require describing the source of the Special Rollover Contribution. A
     person adopting this Plan for the sole purpose of making a Special Rollover
     Contribution shall be treated as a Participant under the Plan for all
     purposes.

SECTION VI TRANSFER OF ASSETS

6.1  The Custodian, in its sole discretion, may accept a transfer of cash or
     Shares from a custodian of a custodial account (or a trustee of a trust)
     maintained as an Individual Retirement Account, or a trustee of a trust
     associated with a qualified retirement or profit-sharing plan. The
     Custodian, by accepting a direct transfer of such assets, does not accept
     the responsibility for the tax results of the transfer, the responsibility
     for which rests with the individual who directs or consents to such
     transfer. The individual for whom the assets are transferred shall become
     the Participant for purposes of this Plan.

SECTION VII SPOUSAL IRA CONTRIBUTIONS

7.1  A Spouse who satisfies the eligibility requirements of Section II may adopt
     this Plan. Such Spouse must execute an Application and establish his/her
     own Custodial Account.

7.2  For any taxable year for which contributions are made by or on behalf of a
     Spouse and his/her Working Spouse to this Plan or any other individual
     retirement account plan, the aggregate amount of such contributions to both
     plans shall not exceed the lesser of the Compensation of the Working Spouse
     within the taxable year or $2,250. This limitation is in addition to the
     limitations contained in paragraphs 3.1 and 3.2 (in the case of the
     Spouse's Plan, the term ``Compensation'' used in paragraph 3.2 shall mean
     the Working Spouse's Compensation). It shall be the sole responsibility of
     the Spouse and Working Spouse to comply with these limitations.

7.3  SPECIAL DEFINITIONS
     (a)  Spouse means a person who (i) is married to a Working Spouse, (ii)
          receives no Compensation or elects to be treated as having received no
          Compensation within his/her taxable year, and (iii) has not attained
          the age of 70 1/2. For purposes of this paragraph, if a spousal IRA
          deduction is claimed on a joint tax return, the Spouse is deemed to
          have elected to be treated as having no Compensation.

     (b)  Working Spouse means a person who (i) is married to a Spouse, (ii) has
          received Compensation within his/her taxable year, and (iii) has not
          attained the age of 70 1/2.

SECTION VIII. CUSTODIAL ACCOUNT AND INVESTMENT OF PLAN ASSETS

8.1  CUSTODIAL ACCOUNT AGREEMENT. Concurrently with the adoption of this Plan,
     the Participant and Custodian shall execute the Custodial Account
     Agreement. Such Agreement shall constitute a part of this Plan. If any
     provisions of the Plan are inconsistent with the provisions of the
     Custodial Account Agreement, the latter shall control.
<PAGE>
 
8.2  INVESTMENT OF CONTRIBUTIONS. The Custodian shall invest all contributions
     solely in Shares of State Farm Funds as directed by Participant.
     Participant (or a Beneficiary of a deceased Participant) may change the
     State Farm Funds in which his/her account is invested as provided in
     paragraph 5.2 of the Custodial Account Agreement.

8.3  REGISTRATION AND OWNERSHIP OF SHARES. Shares acquired by the Custodian
     shall be registered in the name of the Custodian or its nominee. The
     Participant for whom such Shares are acquired shall be the beneficial owner
     of such Shares.

SECTION IX AMENDMENT AND TERMINATION

9.1  AMENDMENT OF PLAN. The Plan Sponsor may, at any time, amend this Plan in
     any respect, by delivering to Participant and the Custodian a signed copy
     of such amendment provided that: (i) no amendment shall be made at any time
     under which any part of the Custodial Account may be diverted to purposes
     other than for the exclusive benefit of Participant and his/her
     Beneficiaries; and (ii) no amendment shall be made retroactively in a
     manner so as to deprive any Participant of any benefit to which he/she was
     entitled under this Plan by reason of contributions made before the
     Amendment unless such Amendment is necessary to conform the Plan or
     Custodial Account Agreement to, or satisfy the requirements of the Internal
     Revenue Code or other applicable law.

9.2  TERMINATION OF PLAN. The Participant may elect to terminate this Plan,
     provided such election is made concurrently with Participant's election to
     terminate the Custodial Account pursuant to paragraph 11.2 of the Custodial
     Account Agreement. Participant shall give written notice of his/her
     election to terminate the Plan to Custodian by registered or certified
     mail.

SECTION X MISCELLANEOUS

10.1 RIGHTS OF PARTICIPANT. Neither the establishment of the Plan, including the
     execution of the Custodial Account Agreement nor any modification or
     amendment thereof, nor the payment of any benefits shall be construed as
     giving to the Participant any legal or equitable right against State Farm
     Funds, the Custodian, or State Farm Investment Management Corp. except as
     provided herein.

10.2 ADMINISTRATION. The Plan shall be administered by the Participant, who
     shall have sole responsibility for the operation of the Plan in accordance
     with its terms; shall determine all questions arising out of the
     administration, except as is otherwise expressly provided in the Plan. The
     Participant shall have sole authority and responsibility to determine the
     amount of contributions and distributions to be made under the Plan and
     neither the Custodian nor any other person shall be responsible therefor,
     or for any consequences to the Participant resulting from the making of
     excess contributions, or the failure to make required distributions, except
     as is otherwise expressly provided in the Plan. Separate records will be
     maintained for the interest of each Participant.

10.3 PAYMENT OF TAXES AND EXPENSES. Any income taxes or other taxes of any kind
     whatsoever that may be levied upon or assessed against or in respect of
     assets of the Plan, or on income arising therefrom, and any transfer taxes,
     and any administrative expenses, maintenance fees, or other charges
     incurred in connection with the Plan or Custodial Account shall be paid
     from the assets of the Custodial Account as provided in the Custodial
     Account Agreement.

10.4 OTHER CONDITIONS. It is a condition of the Plan and the Custodial Account
     Agreement that a Participant, by participating in the Plan, expressly
     agrees that he/she shall look solely to the assets of the Custodial Account
     for the payment of any benefits to which he/she is entitled under the Plan.
     The benefits provided under the Plan shall not be subject to alienation,
     assignment, garnishment, attachment, execution or levy of any kind, and any
     attempt to cause such benefits to be so subjected shall not be recognized,
     except by the Custodian for its fees and expenses under the Custodial
     Account Agreement, and except to such extent as may be required by law. 

     The Plan, Custodial Account Agreement, any forms provided by the Custodian,
     including the Designation of Beneficiary Form filed pursuant to Section IV
     and all property rights of Participant under the Plan, shall be construed,
     administered, and enforced according to the laws of the state of Illinois,
     other than its laws with respect to choice of laws.

10.5 INSTALLMENT PAYMENTS LESS THAN A MINIMUM AMOUNT. Notwithstanding any
     language to the contrary contained herein, if any installment payments
     under sections 4.1 and 4.6 is less than a minimum amount that may be
     established from time to time by the Custodian, then at the option of the
     Custodian, such installment payment may be paid less frequently, but not
     less frequently than annually, or the value of the Custodial Account with
     respect to such installments remaining unpaid may be paid in one sum to the
     person then entitled to receive such payment, the contingent interest of
     any other person notwithstanding.

                               STATE FARM FUNDS
                      INDIVIDUAL RETIREMENT ACCOUNT PLAN
                             DISCLOSURE STATEMENT

The following information is provided to you in accordance with the requirements
of the Internal Revenue Service regulations. You should read this Disclosure
Statement together with the Individual Retirement Account Plan, the Custodial
Account Agreement and the State Farm Funds prospectuses. This is not a
comprehensive discussion of the applicable law; nor is it intended to serve as a
substitute for the advice of your lawyer, accountant or other personal tax or
financial adviser.

1. Irrevocability of Account

  The Internal Revenue Service requires that you receive this Disclosure
Statement at least 7 days prior to the establishment of your Individual
Retirement Account (IRA). Because of this, your Application will not be accepted
by the Custodian and your account will not be established until at least 7 days
after the date you receive this Disclosure Statement. Once your Application for
a State Farm Funds IRA is received and accepted by the Custodian, it cannot be
revoked by you.

2. Internal Revenue Service Approval

  The State Farm Funds Individual Retirement Account Plan and Custodial Account
Agreement have been approved as to form by the Internal Revenue Service. Their
approval is a determination only as to form and not to the merits of the
account.

3. Eligibility

  Participation in the State Farm Funds IRA Plan is limited to Agents and
Employees of the State Farm Insurance Companies and members of their families.

4. General Information

  An IRA must be a United States trust or custodial account created for the
exclusive benefit of an individual and his/her beneficiary. The trustee or
custodian must be either a bank or such other person who has been approved by
the Secretary of the Treasury. No part of the contributions may be invested in
either life insurance contracts or collectibles (such as art works, antiques,
stamps, coins, etc.) as defined in section 408(m) of the Internal Revenue Code.
The assets of the IRA can not be commingled with other property except in a
common trust fund or common investment fund. In addition, an individual's right
to the entire balance in his/her account must at all times be nonforfeitable.

  As with most laws which provide special tax treatment, there are certain
restrictions and limitations. The pertinent Federal tax laws include
requirements relating to contributions, use of account assets, and when and how
distributions can be made to you and your beneficiary.

5. Contributions

  You may make contributions to your IRA for a taxable year if you receive
compensation during such year. Compensation includes your wages and salary as an
employee and earnings from self-employment, such as professional fees and other
amounts for your personal services. However, only a limited amount of
contributions can be made each year to your IRA.
  Limitations - Regular Contributions. Your contributions to your IRA are
limited to the lesser of 100% of your compensation or $2,000 annually. If both
you and your spouse had compensation during the taxable year, then you may each
establish a separate IRA and each of you may make contributions to your separate
IRAs up to the lesser of 100% of your respective compensations or $2,000
annually.
  Limitations - Spousal Contributions. If you had compensation during the
taxable year, your spouse either had no compensation or elected to be treated as
if he/she had no compensation, and you file a joint tax return, you may make
contributions to your IRA and a separate IRA for your spouse. Under such an
arrangement, you may make total contributions to both accounts up to the lesser
of 100% of your compensation or $2,250 annually. To qualify for the maximum
deduction, both IRAs must be funded, but you determine how much to contribute to
each account. However, you can not contribute more than $2,000 annually to
either account. If a spousal IRA deduction is claimed on your tax return for the
taxable year, your spouse is deemed to have elected to be treated as having no
compensation.
  Deductibility of Contributions. Contributions (other than Rollover
Contributions) to your IRA (or your spouse's IRA) may be deductible from your
gross income on your Federal income tax return depending upon your adjusted
gross income and whether or not you are an active participant in a retirement
plan qualified under section 401(a) of the Internal Revenue Code, an annuity
plan under section 403(a) of the Code, an annuity contract under section 403(b)
of the Code, a simplified employee pension under section 408(k) of the Code or a
plan established for its employees by the United States, by a State or political
subdivision or by an agency or an instrumentality of a State or political
subdivision. You are permitted to make deductible IRA contributions up to the
lesser of $2,000 or 100% of compensation if you are not an active participant
(or, if you are married and file a joint return, neither you nor your spouse is
an active participant) in any of the above-mentioned employer-maintained
retirement plans for any part of the plan year ending with or within your
taxable year.
  Even though you are an active participant in an employer-maintained plan, you
are permitted to make deductible IRA contributions up to the lesser of $2,000 or
100% of compensation if you (or you and your spouse if a joint return is filed)
have adjusted gross income that does not exceed an applicable dollar amount. The
applicable dollar amount is (1) $25,000 in the case of an individual, (2)
$40,000 in the case of a married couple filing a joint return, and (3) $0 in the
case of a married couple filing separately. If your adjusted gross income
exceeds the applicable dollar amount (and you are an active participant in one
of the above plans), you may make deductible contributions; however, the IRA
deduction limit (including the spousal IRA deduction limit) is reduced by an
amount that bears the same ratio to the applicable dollar limit as your adjusted
gross income in excess of the applicable dollar limit bears to $10,000.
Accordingly, you may not make deductible IRA contributions if your adjusted
gross income is (1) $35,000 or more, in the case of an individual, (2) $50,000
or more in the case of a married couple filing a joint return, and (3) $10,000
or more in the case of a married couple filing separately. To qualify as a
deductible contribution, your contribution must be made no later than the due
date for filing your Federal income tax return 
<PAGE>
 

(not including any extensions). No deduction for contributions is allowed for
any year in which you are age 70-1/2 or older. Similarly, no deduction is
allowed for a contribution to your spouse's IRA in any year in which he/she is
age 70-1/2 or older.
  You may also make designated nondeductible IRA contributions to the extent
that deductible contributions are not allowed. Thus, you may make nondeductible
contributions to the extent of the excess of (1) the lesser of $2,000 ($2,250 in
the case of a spousal IRA) or 100% of compensation over (2) your IRA deduction
limit. Additionally, you may elect to treat deductible IRA contributions as
nondeductible. Nondeductible IRA contributions must be designated as such on
your tax return in the manner prescribed by the Secretary of the Treasury.
Nondeductible contributions may be made no later than the due date for filing
your Federal income tax return (not including extensions).
  Excess Contributions. Any contributions to your IRA (including spousal
contributions to your spouse's IRA) which exceed the maximum allowable
contribution are excess contributions. Any excess contributions which are not
withdrawn or eliminated prior to the due date for filing your Federal income tax
return (including any extensions) will be subject to a 6% penalty tax under
section 4973 of the Internal Revenue Code.

6. Rollover Contributions

  All or a portion of certain distributions from qualified employer plans or 
tax-sheltered annuities, and distributions from other IRA plans may be "rolled-
over" tax-free to an IRA, if the rollover (transfer) is made within 60 days
after receipt of the distribution. Rollovers from qualified employer plans and
tax-sheltered annuities will be retained in a Special IRA and, under certain
conditions, may be subsequently "rolled-over" tax-free to another qualified
employer plan or tax-sheltered annuity.
  Strict limitations set forth in section 408(d)(3) of the Internal Revenue Code
apply to rollovers. You should seek competent tax advice in order to ensure
compliance with the rules governing tax-free rollovers.

7. Distributions

  Income Tax Treatment. Federal income tax on your deductible IRA contributions,
earnings on such contributions as well as earnings on your nondeductible
contributions, generally, is deferred until you begin to receive distributions
from your account. Such distributions are taxed as ordinary income regardless of
their original source. On the other hand, the distributions of your
nondeductible contributions are generally not subject to income tax at the time
of the distributions since such contributions were previously subject to the
income tax.
  Normal Distributions. The entire interest in your account must be distributed
to you, or begin to be distributed to you, no later than April 1 of the calendar
year following the calendar year in which you reach age 70-1/2. Distributions
may be in single sum payments; substantially equal or unequal installment
payments over a period which can not exceed your life expectancy or the joint
life expectancy of you and your beneficiary; or by purchase of an immediate or
deferred annuity.
  Minimum Distributions. In calendar years after the calendar year in which you
reach age 70-1/2, the law requires you to receive at least a minimum
distribution from your account each year. A 50% penalty tax may be imposed on
any deficiency between the distributions received by you and minimum required
distributions under section 4974 of the Internal Revenue Code.
  Distributions after Death. If you die before the distribution from your
account has begun, the portion of your account balance which is payable to a
designated beneficiary must be distributed to the beneficiary over a period not
to exceed the life expectancy of such beneficiary; any portion not payable to a
designated beneficiary must be distributed by December 31 of the calendar year
containing the fifth anniversary of your death. Additionally, if your designated
beneficiary is your surviving spouse, such spouse may elect, within the five-
year period commencing with your death, to receive substantially equal payments
over a period not to exceed the life expectancy of such spouse beginning by the
later of 1) December 31 of the calendar year following the date of your death,
or 2) December 31 of the calendar year in which you would have reached age
70-1/2. The surviving spouse could change the frequency or amount of these 
payments (subject to the limits of the preceding sentence) at any time.
  Alternatively, your surviving spouse designated beneficiary may elect to
treat the account as his/her own IRA; this election will be deemed to have been
made if your spouse makes a regular or rollover contribution to the account or
if your spouse fails to elect any other distribution option. For the purposes of
this paragraph, any amount paid to your child will be treated as if it had been
paid to your spouse if the remainder of the interest becomes payable to your
surviving spouse when the child reaches the age of majority.
  If you die after the distribution from your account has begun, but before the
entire interest has been distributed, the remaining balance of your account must
be distributed to the designated beneficiary at least as rapidly as under the
method of distribution being used on the date of your death; any portion not
payable to a designated beneficiary must be distributed at least as rapidly as
under the method of distribution being used on the date of your death, but in no
event over a period beyond December 31 of the calendar year containing the fifth
anniversary of your death.
  Premature Distributions. An IRA is intended as a savings plan to accumulate
funds for retirement. Accordingly, section 72(t) of the Internal Revenue Code
imposes a penalty on certain premature distributions. Generally, if you receive
a distribution from your account before you reach age 59-1/2, to the extent that
such distribution will be taxable as ordinary income, it will also be subject to
an additional 10% penalty tax. The additional 10% penalty tax does not apply
when distributions are made because of a permanent disability or your death.
Furthermore, this penalty does not apply to a distribution of an excess
contribution which is timely withdrawn or in the case of a qualifying rollover
distribution.

8. Prohibited Transactions

  If you or your beneficiary were to engage in any prohibited transactions
(described in section 4975(c) of the Internal Revenue Code) with respect to your
IRA (such as any sale, exchange or leasing of any property between you and the
account; or any other interference with the independent status of the account)
then the account would lose its tax-exempt status by reason of section 408(e)
(2)(A) of the Internal Revenue Code and the entire account balance would be
treated as having been distributed to you in the year during which the
prohibited transactions occurred. The value of the entire account would be
included in your gross income and taxed as ordinary income. In addition, if you
are under age 59-1/2, the "distribution" would also be subject to the additional
10% penalty tax imposed on premature distributions.
<PAGE>
 
 
9. Prohibited Transactions - Loans

  You are not permitted to pledge or otherwise use any portion of your IRA as
collateral for a loan. If you do use a portion of your account as collateral,
the portion used will be deemed to have been distributed to you by reason of
section 408(e)(4) of the Internal Revenue Code. The value of the portion
"distributed" would be included in your gross income and taxed as ordinary
income. In addition, if you are under age 59-1/2, the portion "distributed"
would also be subject to the additional 10% penalty tax imposed on premature
distributions.

10. Federal Estate and Gift Taxes

  Transfers of IRA amounts are generally subject to estate and gift taxes in the
absence of any applicable exclusion (such as the unlimited marital deduction or
the unified estate and gift tax credit).

11. Reports to the Internal Revenue Service

  You must file Form 5329 with the Internal Revenue Service for each taxable
year that you owe penalty taxes on excess contributions, premature
distributions, prohibited transactions and underdistributions.

12. Investment of Contributions

  Contributions to your IRA and the earnings thereon, will be invested in shares
of the State Farm Funds selected by you. The assets in your IRA will be held in
a custodial account exclusively for your benefit and the benefit of your
designated beneficiary. The balance in your IRA represents a separate account
which is clearly identified as your property. Your right to the entire balance
in your account is nonforfeitable.

13. Financial Information

  Growth in value of the mutual fund shares held in your account cannot be
guaranteed or projected. The earnings on your account will be derived from the
dividends and capital gain distributions (if any) received on the shares of the
State Farm Funds in your account and will be used to purchase additional shares.
The income and operating expenses of the mutual fund you select, as well as any
increase or decrease in the market value of the underlying assets of the mutual
fund, affects the value of its shares, and therefore the value of the shares in
your account. Additional information regarding each of the State Farm Funds
available for investment in your IRA may be obtained from each Fund's
prospectus.
  Fees and other expenses of maintaining your account may be charged to your

                      INDIVIDUAL RETIREMENT ACCOUNT PLAN
                          CUSTODIAL ACCOUNT AGREEMENT

INTRODUCTION

  The Participant and The Peoples Bank, Bloomington, Illinois (hereinafter
referred to as "Custodian"), by signing the Application have created this
Custodial Account Agreement (hereinafter referred to as the "Agreement"). The
Application is hereby made a part of this Agreement.

  This Agreement has been established in accordance with the State Farm Funds
Individual Retirement Account Plan (hereinafter referred to as the "Plan"). In
the event of any conflict between the provisions of the Plan and those of this
Agreement, the latter shall prevail.

  Participation in the Plan is limited to individuals who qualify to purchase
shares in the State Farm Funds, i.e. Agents and Employees of the State Farm
Insurance Companies and their family members. In the event the Participant
becomes ineligible to purchase shares in the State Farm Funds, no additional
contributions may be made to the Custodial Account established under this
Agreement until the Participant again becomes eligible to purchase such shares.

  The Custodial Account is intended to qualify as an "individual retirement
account" within the meaning of section 408 of the Internal Revenue Code of 1986,
as amended or any successor statute. The Participant has made an initial
contribution (or authorized a compensation deduction) to the Custodial Account
as indicated on the Application. The Participant and Custodian agree that the
terms and conditions of the Custodial Account are as set forth in this
Agreement.

ARTICLE II ESTABLISHMENT OF PARTICIPANT'S CUSTODIAL ACCOUNT

2.1  The Custodian shall establish and maintain a Custodial Account for the sole
     benefit of Participant and his/her Beneficiaries. The Custodial Account
     shall be kept in a manner which will permit an accurate determination of
     the contributions and any other transactions made by the Participant. The
     Participant shall promptly notify the Custodian in writing of any change in
     Participant's name or address.

ARTICLE III CONTRIBUTIONS

3.1  ACCEPTANCE OF CONTRIBUTIONS. The Custodian may accept contributions by
     check or compensation deduction as deposits to the Custodial Account from
     or on behalf of Participant, except as limited by paragraphs 3.2 and 3.3 of

3.2  AMOUNTS OF CONTRIBUTIONS. Except in the case of a Rollover Contribution,
     the Custodian will not accept contributions from or on behalf of the
     Participant in excess of $2,000 for any taxable year of the Participant.
     Contributions for a given taxable year may be made during such year or not
     later than the time prescribed by law for filing Participant's Federal
     income tax return for such taxable year (not including extensions of time
     for filing). All contributions (except Rollover Contributions as described
     in Section V of the Plan) must be made by check or compensation deduction
     and are subject to the minimum investment requirements established by the
     State Farm Funds. Contributions shall be invested pursuant to written
     instructions on a form provided (or permitted) by the Custodian specifying
     the State Farm Fund in which they are to be invested. If the Participant
     becomes ineligible to purchase Shares of the State Farm Funds in accordance
     with eligibility rules established from time to time by the State Farm
     Funds, the Custodian shall not accept contributions to the Custodial
     Account during the period of such ineligibility.

3.3  ROLLOVER CONTRIBUTIONS. The Custodian may accept Rollover Contributions as
     a deposit to the Custodial Account, as described in Section V of the Plan.

ARTICLE V INVESTMENT OF ASSETS OF CUSTODIAL ACCOUNT

5.1  INVESTMENT OF CONTRIBUTIONS. The Custodian shall invest all contributions
     in Shares of the State Farm Funds as directed by Participant on a form
     provided or permitted by the Custodian. If such directions are not received
     by Custodian; or are received but are, in the opinion of the Custodian,
     unclear; or if the accompanying contribution exceeds $2,000 and is not
     identified as a Rollover Contribution; or if the Participant is ineligible
     to purchase Shares; the Custodian may hold or return all of the
     contribution uninvested without liability for loss of income or
     appreciation and without liability for interest pending receipt of proper
     instructions or clarification.

5.2  CHANGE OF INVESTMENT. A Participant (or a Beneficiary of a deceased
     Participant) may change the State Farm Fund in which his/her account is
     invested by filing with the Custodian directions on such form as is
     provided or permitted by the Custodian at such times as the Participant (or
     a Beneficiary of a deceased Participant) shall deem appropriate. No such
     change of investment shall be effective until received by the Custodian
     and, once effective, shall remain in effect until properly changed.

5.3  DIVIDENDS AND DISTRIBUTIONS. All income dividends and capital gain
     distributions received in respect of Shares held in the Custodial Account
     shall be reinvested in Shares of the State Farm Funds from which they were
     received and such Shares shall be credited to the Custodial Account. Such
     reinvestment shall be made on the date specified by the State Farm Funds
     for reinvestment of the distributions. If any distributions may be received
     at the election of the shareowner in additional Shares or in cash, the
     Custodian shall elect to receive such distributions in additional Shares.

5.4  REGISTRATION AND OWNERSHIP OF SHARES. Shares acquired by the Custodian
     shall be registered in the name of the Custodian or its nominee. The
     Custodian shall deliver, or cause to be delivered, to Participant all
     prospectuses, confirmations, notices, reports or other material as may be
     required under applicable securities laws. The Custodian shall not vote any
     such Shares except in accordance with written instructions received from
     Participant.

5.5  MISCELLANEOUS (a) The Custodian does not undertake to render any investment
     advice to the Participant. The responsibility of the Custodian to invest in
     Shares is not an endorsement of any State Farm Fund.

     (b) Anything to the contrary notwithstanding, no part of the assets of the
     Custodial Account shall be invested in life insurance contracts; nor may
     the assets of the Custodial Account be invested in collectibles as defined
     in Section 408(m) of the Internal Revenue Code; nor may the assets of the
     Custodial Account be commingled with other property except in a common
     trust fund or common investment fund (within the meaning of section 408(a)
     (5) of the Internal Revenue Code).

ARTICLE VI PAYMENT OF BENEFITS

6.1  DISTRIBUTIONS. The entire interest of the Participant in the Custodial
     Account must be, or commence to be, distributed no later than April 1 of
     the calendar year following the calendar year in which the Participant
     attains age 70 1/2. Not later than such time, the Participant may elect, in
     a form and at such time as may be acceptable to the Custodian, to have
     his/her interest in the Custodial Account distributed in the manner
     provided in Section IV of the Plan. If the Participant fails or is unable
     to elect one of the methods of distribution described in Section IV of the
     Plan on or before April 1 of the calendar year following the calendar year
     in which Participant attains age 70 1/2, then the Custodian shall make such
     distribution of benefits to Participant in a single sum payment in cash or
     Shares at the sole discretion of the Custodian.

6.2  PAYMENT ON DISABILITY. If the Participant becomes disabled (as defined in
     section 72(m)(7) of the Internal Revenue Code or any successor provision),
     the Custodian shall distribute the Participant's interest in the Custodial
     Account in the manner provided in paragraph 4.8 of the Plan.

6.3  PAYMENT ON DEATH. If Participant dies before distribution of his/her
     interest has begun, or if Participant dies after distribution has commenced
     but before the entire interest has been distributed, the Custodian shall
     distribute the remaining interest in the Custodial Account in the manner
     provided in paragraph 4.6 of the Plan.

6.4  PREMATURE DISTRIBUTION. Before any distribution is made from the Plan to a
     Participant who has not attained age 59 1/2 (except in the case of the
     Participant's death or disability as defined in section 72(m)(7) of the
     Internal Revenue Code), the Participant must furnish the Custodian with a
     declaration of his/her intentions as to the disposition of the amount to be
     distributed.

6.5  EXCESS CONTRIBUTIONS. Anything herein to the contrary notwithstanding, if
     the Custodian should at any time receive written notice from the
     Participant that any contribution made by or on behalf of the Participant
     was an Excess Contribution (as described in section 408(d)(4) of the
     Internal Revenue Code) and Participant directs that such Excess
     Contribution should be distribted to him/her, the Custodian shall
     distribute to the Participant from the Custodial Account the amount of such
     Excess Contribution and, if withdrawn pursuant to section 408(d)(4) of the
     Internal Revenue Code, the net income attributable thereto in Shares or
     cash, in the sole discretion of the Custodian.

6.6  LOSS OF EXEMPTION. On written notice from the Participant or the Internal
     Revenue Service to the Custodian that for any taxable year the
     Participant's account has lost its exemption, including loss of exemption
     as provided in section 408(e)(2) of the Internal Revenue Code, the
     Custodian shall, on or before the close of the ninety-day period beginning
     with the date of the receipt of such notice, distribute to such Participant
     the Participant's entire interest in the Custodial Account in Shares or
     cash in the sole discretion of the Custodian. The Custodian is authorized,
     however, to reserve funds as described in paragraph 10.1.

                                      -2-
<PAGE>
 
6.7  CONFIRMATIONS. The Custodian will confirm to the Participant the redemption
     of Shares made pursuant to any distribution from the Custodial Account.

ARTICLE VII CUSTODIAN FEES AND EXPENSES OF THE ACCOUNT

7.1  ANNUAL MAINTENANCE FEE. For maintaining this Custodial Account, the
     Participant shall pay the Custodian an Annual Maintenance Fee of $1.00.
     With the consent in writing of the Plan Sponsor, the Custodian may change
     the Annual Maintenance Fee from time to time on at least forty-five (45)
     days' notice in writing to the Participant.

7.2  PAYMENT OF FEES AND EXPENSES. Any income, gift, estate, inheritance taxes
     and other taxes of any kind whatsoever that may be levied upon or assessed
     against or in respect of the Custodial Account, the Annual Maintenance Fee,
     and all administrative expenses incurred by the Custodian in the
     performance of its duties, including fees for legal services rendered to
     the Custodian, shall be paid from the assets of the Custodial Account. The
     Custodian may, at its option, collect any amounts so charged from the
     amount of any contribution or distribution from the Custodial Account or by
     sale or liquidation of the Shares credited to the Custodial Account and, if
     the assets of the Custodial Account are insufficient to satisfy such
     charges, the Participant shall pay any deficit therein to the Custodian.

ARTICLE VIII REPORTING AND DISCLOSURE

8.1  INFORMATION. The Participant agrees to provide information to the Custodian
     at such time and in such manner and containing such information as may be
     necessary for the Custodian to prepare any reports required by the Internal
     Revenue Service.

8.2  REPORTS. The Custodian agrees to submit reports to the Internal Revenue
     Service and the Participant at such time and in such manner and containing
     such information as is prescribed by the Internal Revenue Service.

ARTICLE IX ADDITIONAL PROVISIONS REGARDING THE CUSTODIAN

9.1  CUSTODIAL ACCOUNT STATEMENTS. The Custodian shall keep accurate and
     detailed records of all transactions it is required to perform hereunder.
     Within sixty (60) days after the close of each calendar year (or after the
     Custodian's resignation or removal pursuant to Article X hereof), the
     Custodian shall deliver to the Participant a written statement of the
     transactions effected by the Custodian during such year (or period ending
     with such resignation or removal) and the fair market value of the assets
     of the Custodial Account as of the close of such year. Upon expiration of
     the sixty (60) day period following the date on which the foregoing
     statement is delivered by the Custodian, the Custodian shall (to the extent
     permitted by applicable law) be forever released and discharged from all
     liability and accountability to anyone with respect to its acts in
     transactions shown on or reflected by such statement, except with respect
     to any such acts or transactions as to which the Participant has filed
     written objections with the Custodian within the sixty (60) day period.
     Nothing herein contained shall be deemed to preclude the Custodian from its
     right to have its accounts judicially settled by a court of competent
     jurisdiction.

9.2  MISCELLANEOUS. The Custodian shall not be liable and assumes no
     responsibility for the collection of contributions provided for under the
     Plan, the deductibility of any contributions, the purpose or propriety of
     any distribution made pursuant to Article VI hereof, or any other action
     taken at a Participant's direction, nor shall the Custodian have any duty
     or responsibility to determine whether information furnished by a
     Participant is correct. To the extent permitted by Federal law, nothing
     contained in the Plan, either expressly or by implication, shall be deemed
     to impose any powers, duties or responsibilities on the Custodian other
     than those set forth in this Agreement.

     The Custodian shall be indemnified and saved harmless by the Participant
     from any and all liability whatsoever which may arise in connection with
     this Agreement, except the obligation of the Custodian to perform in
     accordance with the Agreement and with the applicable Federal law.

     The Custodian shall be under no duty to take any action other than as
     herein specified with respect to the Custodial Account unless the
     Participant shall furnish the Custodian with instructions in proper form
     and such instructions shall have been specifically agreed to by the
     Custodian. The Custodian shall be under no duties to defend or engage in
     any suit with respect to the Custodial Account unless the Custodian shall
     have first agreed in writing to do so and shall have been fully indemnified
     to the satisfaction of the Custodian. The Custodian shall be protected in
     acting upon any written order or direction from a Participant or any other
     notice, request, consent, certificate or any other instrument believed by
     it to be genuine and to have been properly executed and, so long as it acts
     in good faith, in taking or omitting to take any other action.

     Before making any distribution in the case of the death of the Participant,
     the Custodian shall be furnished with such certified death certificates,
     inheritance tax releases, indemnity agreements and other documents as may
     be required by the Custodian. Before making any distribution in the case of
     the disability of a Participant, the Custodian shall be furnished with
     proof of disability.

     The Custodian shall be an agent for the Participant to receive and invest
     contributions as directed by the Participant, hold and distribute such
     investments, and keep adequate records and report thereon, all in
     accordance with this Agreement. The parties do not intend to confer any
     fiduciary duties on the Custodian, and none shall be implied. The Custodian
     may perform any of its duties through other persons designated by the
     Custodian from time to time, and the Custodian intends initially to
     delegate all such duties to State Farm Investment Management Corp. No such
     delegation or future change therein shall be considered as an amendment to
     this Agreement.

ARTICLE X RESIGNATION OF OR REMOVAL OF CUSTODIAN

10.1 The Custodian may resign at any time upon at least thirty (30) days' notice
     in writing to the Participant and to the Plan Sponsor, and Custodian and
     Participant agree that the Plan Sponsor may remove the Custodian at any
     time upon at least thirty (30) days' notice in writing to the Custodian and
     Participant. Upon such resignation or removal, the Plan Sponsor shall
     appoint a Successor Custodian. Upon receipt by the Custodian of a written
     acceptance of such appointment by a Successor Custodian, the Custodian
     shall transfer to such Successor the assets of the Custodial Account and
     all records pertaining thereto. The Custodian is authorized, however, to
     reserve such a portion of such assets as it may deem advisable for payment
     of all its fees, compensation, costs and expenses or for payment of any
     other liabilities constituting a charge on or against the assets of the
     Custodial Account or on or against the Custodian, with any balance of such
     reserve remaining after the payment of all such items to be paid over to
     the Successor Custodian. The Successor Custodian shall hold the assets paid
     over to it under the terms of this Agreement.

10.2 The Custodian shall not be liable for the acts or omissions of any
     Successor Custodian.

10.3 The Custodian and every Successor Custodian appointed to serve under this
     Agreement, must be a bank as defined in section 408(n) of the Internal
     Revenue Code or such other person who demonstrates to the satisfaction of
     the Secretary of the Treasury or his delegate that the manner in which such
     other person will administer the Custodial Account will be consistent with
     the requirements of section 408 of the Internal Revenue Code.

10.4 After the Custodian has transferred the Custodial Account assets (including
     any reserve balance as contemplated above) to the Successor Custodian, the
     Custodian shall be relieved of all further liability with respect to this
     Agreement, the Custodial Account and the assets thereof.

ARTICLE XI TERMINATION OF CUSTODIAL ACCOUNT

11.1 TERMINATION BY CUSTODIAN. The Custodian may elect to terminate the
     Custodial Account if, within sixty (60) days after its resignation or
     removal pursuant to Article X, the Plan Sponsor has not appointed a
     Successor Custodian which has accepted such appointment. Termination of the
     Custodial Account shall be effected by distributing to Participant all
     assets of the Custodial Account in a lump-sum payment in cash or Shares, at
     the sole discretion of Custodian, subject to Custodian's right to reserve
     funds as described in paragraph 10.1.

11.2 TERMINATION BY PARTICIPANT. The Participant may elect to terminate the
     Custodial Account at any time, provided such election is made concurrently
     with Participant's election to terminate the Plan pursuant to paragraph 9.2
     of the Plan. Participant shall give written notice of his/her election to
     terminate the Custodial Account to the Custodian by registered or certified
     mail. After receipt of such notice, the Custodian shall terminate the
     Custodial Account and distribute all assets in the Custodial Account
     pursuant to directions furnished by Participant and agreed to by Custodian.
     If Participant fails or is unable to furnish such directions, the Custodian
     shall distribute to Participant all assets of the Custodial Account in a
     lump-sum payment in cash or Shares, at the sole discretion of Custodian,
     subject to Custodian's right to reserve funds as described in paragraph
     10.1.

11.3 TERMINATION OF AGREEMENT. Upon distribution of all assets of the Custodial
     Account in accordance with the provisions of paragraphs 11.1 or 11.2, this
     Agreement shall terminate and have no further force and effect. The
     Custodian shall be relieved from all further liability with respect to this
     Agreement, the Custodial Account and all assets thereof so distributed.

ARTICLE XII AMENDMENT

12.1 Subject to the provisions of paragraphs 12.2, 12.3, and 12.4, the
     Participant and Custodian agree that the Plan Sponsor may, at any time,
     unilaterally amend this Agreement in any respect (including retroactive
     amendments). Any such Amendment shall be effective on a stated date which
     shall be at least sixty (60) days after giving written notice of the
     Amendment (including its exact terms) to Participant and Custodian. The
     Participant and Custodian shall be deemed to have consented to such
     Amendment unless, within thirty (30) days after the notice to Participant
     and Custodian is mailed, either (i) Participant elects to terminate the
     Custodial Account as provided under Article XI, or (ii) Custodian elects to
     resign as provided in Article X.

12.2 No amendment shall be made at any time under which any part of the
     Custodial Account may be diverted to purposes other than for the exclusive
     benefit of Participant and his/her Beneficiaries.

12.3 No amendment shall be made retroactively in a manner so as to deprive any
     Participant of any benefit to which he/she was entitled under this
     Agreement by reason of contributions made before the Amendment, unless such
     Amendment is necessary to conform the Plan or Agreement to, or satisfy the
     requirements of, the Internal Revenue Code or other applicable law.

12.4 No amendment shall place any greater burden on the Custodian without its
     written consent.

12.5 This Article XII shall not be construed to restrict the freedom of the
     Custodian to change the Annual Maintenance Fee in the manner provided in
     Article VII, and no such change shall be deemed an Amendment of this
     Agreement.

                                      -4-

     3.2, 3.3 and 5.5(b) and this sentence shall be controlling. Furthermore,
