                                  PROSPECTUS
                                ________, 1997

State Farm Variable Product Trust is an investment company consisting of six
separate investment portfolios or funds (the "Funds"), each of which has
different investment objectives.

The MONEY MARKET FUND seeks to maximize current income to the extent consistent
with the preservation of capital and maintenance of liquidity. This Fund will
pursue its objective by investing exclusively in high quality money market
instruments. AN INVESTMENT IN THE MONEY MARKET FUND IS NEITHER INSURED NOR
GUARANTEED BY THE U.S. GOVERNMENT. This Fund will attempt to maintain a stable
net asset value of $1.00 per share, BUT THERE CAN BE NO ASSURANCE THAT THE FUND
WILL BE ABLE TO DO SO.
    
The LARGE CAP EQUITY INDEX FUND seeks to match the performance of the Standard &
Poor's Composite Index of 500 Stocks (the "S&P 500"). This Fund will pursue its
objective by investing primarily on a capitalization-weighted basis in the
securities comprising the index.      
    
The SMALL CAP EQUITY INDEX FUND seeks to match the performance of the Russell
2000 Small Stock Index (the "Russell 2000"). This Fund will pursue its objective
by investing primarily in a representative sample of stocks found in the index. 
     
    
The INTERNATIONAL EQUITY INDEX FUND seeks to match the performance of the Morgan
Stanley Capital International Europe, Australia and Far East Free Index (the 
"EAFE Free"). This Fund will pursue its objective by investing primarily in a
representative sample of stocks found in the index.     

The BOND FUND seeks to realize over a period of years the highest yield
consistent with prudent investment management through current income and capital
gains. This Fund will pursue its objective by investing primarily in high
quality debt securities.

The STOCK AND BOND BALANCED FUND seeks long-term growth of capital, balanced
with current income. This Fund will pursue its objective by investing primarily
in the Trust's Large Cap Equity Index Fund and Bond Fund.

These Funds are available to the public only through the purchase of certain
variable annuity and variable life insurance contracts issued by State Farm Life
Insurance Company and State Farm Life and Accident Assurance Company.

This prospectus provides vital information about the Trust. For your own benefit
and protection, you should read it thoroughly before investing and keep it on
hand for future reference. A Statement of Additional Information containing
additional information about the Trust has been filed with the Securities and
Exchange Commission, and may be obtained without charge by sending a written
request to the Trust at the above address or calling the telephone number shown.
The Statement of Additional Information is considered part of this prospectus,
and is incorporated herein by reference.

SHARES OF THE TRUST ARE NOT DEPOSITS OR OBLIGATIONS OF, OR GUARANTEED OR
ENDORSED BY, ANY BANK OR OTHER INSURED DEPOSITORY INSTITUTION, AND ARE NOT
INSURED BY THE FEDERAL DEPOSIT INSURANCE CORPORATION OR ANY OTHER GOVERNMENT
AGENCY. AN INVESTMENT IN ANY OF THE FUNDS INVOLVES INVESTMENT RISK INCLUDING
POSSIBLE LOSS OF PRINCIPAL.

         THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE
           SECURITIES & EXCHANGE COMMISSION, NOR HAS THE COMMISSION
           PASSED UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS.
           ANY REPRESENTATION TO THE CONTRARY IS A CRIMINAL OFFENSE.

                       STATE FARM VARIABLE PRODUCT TRUST

                                ABOUT THE TRUST

State Farm Variable Product Trust (the "Trust") is an open-end management
investment company organized as a business trust under the laws of the State of
Delaware on February 21, 1997. The Trust consists of six separate investment
portfolios (the "Funds" or a "Fund"), each of which is, in effect, a separate
mutual fund. The Trust issues a separate series of shares of beneficial interest
for each Fund representing fractional undivided interests in that Fund. By
investing in a Fund, you become entitled to a pro-rata share of all dividends
and distributions arising from the net income and capital gains on the
investments of that Fund. Likewise, you share pro-rata in any losses of that
Fund.
    
Pursuant to investment advisory agreements and subject to the authority of the
Trust's Board of Trustees, State Farm Investment Management Corp. ("SFIM")
serves as the Trust's investment adviser and conducts the business and affairs
of the Trust. SFIM has engaged Barclays Global Fund Advisors ("BGFA") as the
investment sub-adviser to provide day-to-day portfolio management for the Large
Cap, Small Cap, and International Equity Index Funds. (The term "investment
adviser" in this prospectus may mean either SFIM or BGFA, as appropriate.)     
    
The Trust currently offers the shares of each Fund to separate accounts of State
Farm Life Insurance Company as funding vehicles for certain variable annuity and
life insurance contracts (the "Contracts") issued by State Farm Life Insurance
Company through such separate accounts. The Trust also intends to offer shares
of each Fund to separate accounts of State Farm Life and Accident Assurance
Company as funding vehicles for certain variable annuity and life insurance
contracts issued by State Farm Life and Accident Assurance Company through such
separate accounts. (State Farm Life Insurance Company and State Farm Life and
Accident Assurance Company are collectively referred to herein as "State Farm";
the variable annuity and variable life insurance contracts issued by State Farm
are collectively referred to herein as the "Contracts"; and the State Farm
separate accounts are collectively referred to as the "Accounts"). The Trust
does not offer its shares directly to the general public. The Accounts, like the
Trust, are registered as investment companies with the SEC and separate
prospectuses, one of which accompanies this prospectus, describe each Account
and the Contract being offered through that Account. The Trust may, in the
future, offer its shares to other registered and unregistered separate accounts
of State Farm and its affiliates supporting other variable annuity or variable
life insurance contracts and, subject to obtaining required regulatory
approvals, to qualified pension and retirement plans.    

                      INVESTMENT OBJECTIVES AND POLICIES
    
Each Fund has one or more investment objectives and related investment policies
and uses various investment techniques to pursue these objectives and policies.
THERE CAN BE NO ASSURANCE THAT ANY OF THE FUNDS WILL ACHIEVE ITS INVESTMENT
OBJECTIVE OR OBJECTIVES. You should not consider any one Fund alone to be a
complete investment program. All of the Funds are subject to the risk of
changing economic conditions. The Bond Fund and Stock and Bond Balanced Fund are
also subject to the risk inherent in the ability of the Fund's investment
adviser to make changes in the composition of the Fund in anticipation of
changes in economic, business, and financial conditions. As with any 
security,     

                                      
<PAGE>
 
a risk of loss is inherent in an investment in the shares of any of the Funds.
    
In addition to these general risks, the different types of securities,
investments, and investment techniques used by each Fund all have attendant
risks of varying degrees. With respect to equity securities, there can be no
assurance of capital appreciation and there is a substantial risk of decline.
With respect to debt instruments, there exists the risk that the issuer of the
security may not be able to meet its obligations on interest or principal
payments at the time required by the instrument. In addition, the value of debt
instruments generally rises and falls inversely with prevailing current interest
rates. Moreover, foreign investments and investments in small capitalization
issuers entail special additional risks. For a more detailed explanation of the
risks associated with and a definition of "foreign investments," see "Foreign
Investments" in this prospectus and the statement of additional information
("SAI").     

Certain types of investments and investment techniques common to one or more
Funds are described in greater detail, including the risks of each, under
"Investment Techniques" in this prospectus and in the SAI.
    
The investment objective or objectives of each Fund are fundamental and may not
be changed without the approval of a majority of the outstanding voting shares
of the series related to that Fund. Certain investment restrictions also are
fundamental and cannot be changed without shareholder approval. In contrast,
certain other investment restrictions as well as the investment policies and
techniques of each Fund are not fundamental and may be changed by the Trust's
Board of Trustees without shareholder approval. These investment objectives,
restrictions, policies and techniques are described below and in more detail in
the SAI.     

THE MONEY MARKET FUND

The Money Market Fund seeks to maximize current income to the extent consistent
with the preservation of capital and maintenance of liquidity. This Fund will
pursue its objective by investing exclusively in the following high quality
money market instruments:

     1.   U.S. Government securities (as defined in the SAI) and related custody
          receipts;

     2.   obligations issued or guaranteed by U.S. banks (including certificates
          of deposit, bank notes, loan participation interests, commercial
          paper, unsecured promissory notes, time deposits, and bankers'
          acceptances) that have more than $1 billion in total assets at the
          time of purchase as well as debt obligations of U.S. subsidiaries of
          such banks and, certificates of deposit and promissory notes issued by
          Canadian affiliates of such banks, provided that such obligations are
          guaranteed as to principal and interest by such banks;

                                      
<PAGE>
 
     
     3.   commercial paper (unsecured promissory notes including variable amount
          master demand notes) issued or guaranteed by U.S. corporations or
          other entities that are, at the time of purchase, rated in the two
          highest rating categories for short-term debt obligations of at least
          one nationally recognized statistical rating organization 
          ("NRSRO");     

     4.   asset-backed securities (including interests in pools of assets such
          as motor vehicle installment purchase obligations and credit card
          receivables);

     5.   other short-term obligations issued or guaranteed by U.S.
          corporations, state and municipal governments or other entities;

     6.   unrated notes, paper, obligations or other instruments that SFIM
          determines to be of comparable high quality; and

     7.   repurchase agreements with banks and government securities dealers
          that are recognized as primary dealers by the Federal Reserve System,
          provided that:

          (a)  at the time that the repurchase agreement is entered into, and
               throughout the duration of the agreement, the collateral has a
               market value at least equal to the value of the repurchase
               agreement; and

          (b)  the collateral consists of U.S. Government securities or
               instruments that are rated in the highest rating category by the
               requisite NRSROs (as defined below).

The Money Market Fund may acquire any of the above securities on a forward
commitment or when-issued basis, and may lend portfolio securities and invest in
other investment companies. See "Investment Techniques" in this prospectus for
more detailed information.
    
The Money Market Fund will only invest in instruments denominated in U.S.
dollars that SFIM, under the supervision of the Trust's Board of Trustees,
determines present minimal credit risk and meet, at the time of acquisition,
certain minimum credit rating requirements described in the SAI.     

The Money Market Fund will invest at least 95% of its total assets in securities
that are rated in the highest category by the requisite NRSROs or unrated
securities of comparable investment quality. Of securities not rated in the
highest category (or not of comparable quality), the Fund will not invest more
than the greater of 1% of its total assets or $1 million in the securities of
any single issuer. The Fund is diversified. Except as explained in the SAI, the
Fund will not invest more than 5% of its net assets in securities of any single
issuer 

                                      
<PAGE>
 
(except U.S. Government securities or repurchase agreements collateralized by
such securities).

All portfolio instruments owned by the Money Market Fund will mature within 13
months or less of the time that they are acquired. The average maturity of the
portfolio securities owned by the Fund based on their dollar value will not
exceed 90 days at the time of each investment. If the disposition of a portfolio
security results in a dollar-weighted average portfolio maturity in excess of 90
days, the Money Market Fund will invest its available cash in such manner as to
reduce its dollar-weighted average portfolio maturity to 90 days or less as soon
as is reasonably practicable.

See Appendix A to the SAI for additional information on the types of money
market instruments in which the Money Market Fund may invest.

NRSROs include S&P, Moody's, Fitch Investors Service, Inc., Duff & Phelps, Inc.,
IBCA Limited and its affiliate IBCA Inc., and Thompson BankWatch. See Appendix B
to the SAI for a description of each NRSRO's rating categories.

THE EQUITY INDEX FUNDS
    
The Large Cap, Small Cap, and International Equity Index Funds are equity index
Funds that invest mostly in stocks, although each may also invest in stock index
futures contracts and options on such futures contracts. By investing in a broad
range of stocks within a specific index (a "benchmark index"), each of these
Funds avoids the risks of individual stock selection and instead, seeks to match
the performance of its benchmark index, whether that index goes up or down.
These Funds do not have, and will not adopt, a defensive investment strategy in
times of generally declining stock prices, and you bear the risk of such a
market decline with an investment in any of these Funds.    

What is an index? An index is a grouping of securities, such as stocks, bonds or
commodities, used to measure and report changes in a particular market. An index
may be comprised of many securities and designed to be representative of the
overall market, or made up of a smaller number of securities and designed to
reflect a particular industry or market sector. The composition and weighting of
securities in an index can, and often does, change.

Which indices do these Funds follow? While there are more than a hundred
different indices, each of the equity index Funds try to match the performance
of a very prominent stock index. Each equity index Fund has the fundamental
investment objective of seeking to match the investment return of its benchmark
index.

                                      
<PAGE>
 
The Large Cap Equity Index Fund's benchmark index is the S&P 500./1/  This Fund
will pursue its objective of seeking to match the return of that index by
investing primarily on a capitalization-weighted basis in the securities 
comprising the index, i.e., by purchasing each of the stocks comprising the S&P
                      -----
500 in the same weighted proportions that such stocks have in the index. The S&P
500 tracks the common stock performance of large U.S. companies in the
manufacturing, utilities, transportation, and financial industries. It also
tracks the performance of common stocks issued by foreign and smaller U.S.
companies in similar industries. In total, the S&P 500 is comprised of 500
common stocks.

Like the S&P 500, the Large Cap Equity Index Fund will hold both dividend paying
and non-dividend paying common stocks.
    
The Small Cap Equity Index Fund's benchmark index is the Russell 2000./2/ This
Fund will pursue its objective of seeking to match the return of that index by
investing primarily in a diversified portfolio of common stocks that will
reflect, as a group, the total investment return of that index. The Russell 2000
tracks the common stock performance of the 2,000 smallest U.S. companies in the
Russell 3000 Index, which represents approximately 10% of the total
capitalization of the Russell 3000 Index. The Frank Russell Company created the
Russell 2000 in the 1980s to give investors an idea of how the stocks of smaller
companies generally perform. As of the latest reconstitution of the Russell
2000, the average market capitalization was approximately $421 million, the
median market capitalization was approximately $352 million, and the largest
company in the index had an approximate market capitalization of $1.0 billion.
The stocks comprising the Russell 2000 are updated annually because many of the
companies in the index either outgrow the index or fall in value.

The International Equity Index Fund's benchmark index is the EAFE Free./3/ This
Fund will pursue its objective of seeking to match the return of that index by
investing primarily in a diversified portfolio of common stocks that will
reflect, as a group, the total investment return of that index. The EAFE Free is
a diversified index developed by Morgan Stanley Capital International in 1970.
As of December 31, 1995, the EAFE Free included the common stocks (or equity
securities having investment characteristics of common stocks) of over 1,100
companies. The EAFE Free currently measures the performance of stock markets of
Europe (Austria, Belgium, Denmark, Finland, France, Germany, Ireland, Italy, the
Netherlands, Norway, Spain, Sweden, Switzerland and the United Kingdom),
Australia, New Zealand, and the Far East (Hong Kong, Japan, Malaysia, and
Singapore). Unlike MSCI's standard indices, the Free indices take into account
local market restrictions on share ownership by foreigners. EAFE Free is meant
to reflect actual opportunities for foreign investors in a local market.     
    
Since EAFE Free is an index of international stocks, BGFA may invest up to 100%
of the International Equity Index Fund's total assets in foreign stocks (listed
and over-the-counter) that comprise the EAFE Free.     
    
How are the index Funds managed? BGFA does not manage the equity index Funds
according to traditional methods of "active" investment management, which
involve the buying and selling of securities based upon economic, financial and
market analysis and investment judgment. Instead, BGFA utilizes a "passive" or
indexing investment approach for each equity index Fund, attempting to
approximate the investment performance of the appropriate benchmark index
through quantitative analytical procedures. Stocks are selected for inclusion in
an equity index Fund's portfolio in order to have aggregate investment
characteristics (based on market capitalization and industry weightings),
fundamental characteristics (such as return variability, earnings valuation and
yield) and liquidity measures similar to those of the benchmark index taken in
its entirety.

<PAGE>
 
     
Each equity index Fund will attempt to remain as fully invested as practicable
in a pool of equity securities the performance of which is expected to
approximate the performance of its benchmark index taken in its entirety. An
equity index Fund will normally invest at least 90% of its total assets in
stocks that are represented in its benchmark index and will at all times invest
a substantial portion of its total assets in such stocks.     
    
Do the index Funds hold every stock in their indices? The Large Cap Equity Index
Fund will generally hold every stock in the S&P 500. However, each of the Small
Cap and International Equity Index Funds generally will not hold all of the
issues that comprise its benchmark index, due in part to the costs involved and,
in certain instances, the potential illiquidity of certain securities. Instead,
the Small Cap Equity Index Fund will attempt to hold a representative sample of
the securities in its benchmark index, which will be selected by BGFA utilizing
quantitative analytical models in a technique known as "portfolio sampling."
Under this technique, each stock is considered for inclusion in the Fund based
on its contribution to certain capitalization, industry and fundamental
investment characteristics. The International Equity Index Fund will hold
securities which will be selected by BGFA utilizing a quantitative model known
as minimum variance optimization. Under this technique, stocks are selected for
inclusion if the fundamental investment characteristics of the security reduce
the portfolio's predicted tracking error against the benchmark index. BGFA will
seek to construct the portfolio of each of the Small Cap and International
Equity Index Funds so that, in the aggregate, its capitalization, industry and
fundamental investment characteristics perform like those of its benchmark
index. Over time, the portfolio composition of these two Funds may be altered
(or "rebalanced") to reflect changes in the characteristics of its benchmark
index or with a view to bringing the performance and characteristics of the
equity index Fund more in line with that of its benchmark index. Such
rebalancings will require the equity index Fund to incur transaction costs and
other expenses. Each of the Small Cap and International Equity Index Funds
reserves the right to invest in all of the securities in the benchmark 
index.     
    
What other investments do the index Funds make? An equity index Fund may invest
any assets not invested in stocks that are represented in its benchmark index
(its "remaining assets") in the same type of short-term high quality debt
securities in which the Money Market Fund invests (described above), stock index
futures contracts, options on such futures contracts, and/or cash. Such
investments may be made to invest uncommitted cash balances and to assist in
meeting shareholder redemptions. The International Equity Index Fund may also
enter into foreign currency forward and foreign currency futures contracts to
facilitate settlements in local markets, in connection with stock index futures
positions, and to protect against currency exposure in connection with its
distributions to shareholders, but may not enter into such contracts for
speculative purposes or as a way of protecting against anticipated adverse
changes in exchange rates between foreign currencies and the U.S. dollar. A 
foreign currency forward contract is an obligation to purchase or sell a
specific currency at a future date, which may be any fixed number of days from
the date of the contract agreed upon by the parties, at a price set at the time
of the contract. An equity index Fund will not invest its remaining assets as
part of a temporary defensive strategy to protect against potential stock market
declines.    
    
When and why are these futures contracts and options on futures contracts used?
An equity index Fund may purchase stock index futures contracts on its benchmark
index or a comparable stock index to simulate investment in its benchmark index.
This may be done to rapidly gain exposure to the securities comprising its
benchmark index in anticipation of purchasing such securities over time, to
reduce transaction costs, or to gain exposure to such securities at a lower cost
than by making direct investments in the cash market. If an equity index Fund
cannot sell a futures contract that it holds, it may write call and buy put
options on the contract to effectively close out or offset the contract. The
equity index Funds will not use futures contracts or options on futures
contracts     
                                      
<PAGE>
 
to leverage net assets. See "Financial Futures Contracts and Options on Such
Contracts" in this prospectus for more detailed information.
    
How closely can an index Fund match the performance of its benchmark index? All
three equity index Funds attempt to match the performance of their benchmark
indices, although the Trust cannot guarantee that any of the Funds will be able
to do so. Due to the use of the portfolio sampling and optimization techniques
described above, the Small Cap and International Equity Index Funds are not
expected to track their benchmark indicies with the same degree of accuracy as
would an investment vehicle that invested in every component security of its
benchmark index. BGFA expects that, over time, the "expected tracking error" of
an equity index Fund relative to the performance of its benchmark index will be
less than 5%. BGFA will monitor the tracking error of each equity index Fund on
an ongoing basis and will seek to minimize tracking error to the extent
possible. There can be no assurance that any equity index Fund will achieve any
particular level of tracking error relative to the performance of the relevant
benchmark index. For an explanation of "expected tracking error" and more
information on this subject, see the SAI.     
    
What are some of the other risks associated with the index Funds? The Small Cap
Equity Index Fund invests in many small U.S. companies, which entail special
risks. For a discussion of the risks of investing in small capitalization
issuers, see "Investments in Securities of Small Capitalization Issuers," in
this prospectus. In addition, the Large Cap Equity Index and International
Equity Index Funds may make foreign investments, which may present the potential
for certain benefits not generally present in domestic equity investments, but
are also subject to special risks. See "Foreign Investments" for a definition
of, and more details on the benefits and risks of, foreign investments.     

THE BOND FUND

The Bond Fund seeks to realize over a period of years the highest yield
consistent with prudent investment management through current income and capital
gains. This Fund will pursue its objective by investing primarily in debt
securities rated A or better by Standard & Poor's or A or better by Moody's and
in U.S. Government securities. Under normal circumstances, at least 65% of the
Fund's total assets will be invested in debt securities that are rated A or
better or that are unrated but of equivalent quality.

The Bond Fund generally seeks to maintain a dollar weighted average portfolio
duration of less than six years. Duration represents the weighted average
maturity of expected cash flows on a debt obligation, discounted to present
value. The longer the duration of a debt obligation, the more sensitive its
value is to changes in interest rates. Maturity measures only the time final
payment is due on a bond or other debt security; it takes no account of the
pattern of a 

                                      
<PAGE>
 
security's cash flows over time. In computing the duration of its portfolio, the
Bond Fund will have to estimate the duration of debt obligations that are
subject to prepayment or redemption by the issuer.
    
From time to time, up to 20% of the Bond Fund's total assets may be invested 
in debt securities which are rated lower than A by Standard & Poor's or Moody's
or comparable unrated debt securities or in convertible debt securities,
convertible preferred stocks and nonconvertible preferred stocks rated within
the three highest grades of Standard & Poor's or Moody's applicable to such
securities. To the extent that the Bond Fund invests in such securities, the
Bond Fund's investment portfolio will be subject to relatively greater risk of
loss of income and principal. Securities rated BBB or lower by Standard & Poor's
or Baa or lower by Moody's are considered by those rating agencies to have
varying degrees of speculative characteristics. Consequently, although they can
be expected to provide higher yields, such securities may be subject to greater
market value fluctuations and greater risk of loss of income and principal than
lower-yielding, higher-rated fixed-income securities.     
    
The Bond Fund will not directly purchase common stocks. However, it may retain
common stocks acquired either by conversion of debt securities or by the
exercise of warrants attached to debt securities.      
    
When appropriate, in SFIM's opinion, based upon prevailing market or economic
conditions, the Bond Fund for temporary defensive purposes may invest up to 
100% of its total assets in other types of securities, including securities in
which the Money Market Fund may invest, or it may retain funds in cash. See the
description of the Money Market Fund above and Appendix A to the SAI.      
    
Although, in SFIM's opinion, the risk of loss of principal should be lessened by
the quality of the investments in which the Bond Fund will primarily invest, the
Bond Fund may be subject to substantial price changes resulting from market
yield fluctuations with respect to holdings of longer maturities that typically
provide the best yields.      

THE STOCK AND BOND BALANCED FUND

The Stock and Bond Balanced Fund seeks long-term growth of capital, balanced
with current income. This Fund will pursue its objective by investing primarily
in shares of the Trust's Large Cap Equity Index Fund and Bond Fund
(collectively, the "underlying Funds").
    
Under normal circumstances, the Stock and Bond Balanced Fund will attempt to
maintain approximately 60% of its net assets in shares of the Large Cap Equity
Index Fund and approximately 40% of its net assets in shares of the Bond Fund.
The Stock and Bond Balanced Fund will never invest more than 75% of its net 
assets in either underlying Fund. Though the Stock and Bond     
                                      
<PAGE>
 
Balanced Fund is not an asset allocation or market timing fund, it will, over
time, adjust the amount of its net assets invested in each underlying Fund
within the limits prescribed above as economic, market and financial conditions
warrant.
    
The Stock and Bond Balanced Fund may hold a portion of its assets in U.S.
Government securities, short-term paper, or may invest in the Money Market Fund
to provide flexibility in meeting redemptions, expenses, and the timing of new
investments, and serves as a short-term defense during periods of unusual
volatility. For temporary defensive purposes, the Stock and Bond Balanced Fund
may invest without limitation in such securities.      
    
Special Risk Considerations. To the extent that the Stock and Bond Balanced Fund
invests in shares of other Funds, the risks associated with those other Funds
are also associated with an investment in the Stock and Bond Balanced Fund.
Also, since the Stock and Bond Balanced Fund's investments are concentrated in
the underlying Funds, the Stock and Bond Balanced Fund's performance is directly
related to the performance of the underlying Funds. The investment objectives,
restrictions, investment techniques and risks associated with each of the
underlying Funds are described elsewhere in this prospectus and in the SAI.     

Diversification. The Stock and Bond Balanced Fund is a "nondiversified"
investment company for purposes of the Investment Company Act of 1940 because it
invests in the securities of a limited number of mutual funds. However, the
underlying Funds themselves are diversified investment companies, and the Stock
and Bond Balanced Fund intends to qualify as a diversified investment company
for the purposes of Subchapter M of the Internal Revenue Code.

                             INVESTMENT TECHNIQUES

In pursuing their investment objectives, the Funds may engage in the following
investment techniques.

LOANS OF PORTFOLIO SECURITIES
    
Each Fund may from time to time lend securities it holds to brokers, dealers,
and financial institutions, up to a maximum of 33% of the total value of that
Fund's assets. Such loans will be secured by collateral in the form of cash or
U.S. Treasury securities, which will be maintained in an amount at least equal
to the current market value of the loaned securities. Each Fund will continue to
receive interest and dividends on the loaned securities during the term of its
loans, and, in addition, will receive either a fee from the borrower or interest
earned from the investment of cash collateral in short-term securities. Each
Fund also will receive any gain or loss in the market value of its loaned
securities and of securities in which cash collateral is invested during the
term of the loan. The primary risk involved in lending      

                                       
<PAGE>
 
securities is that the borrower will fail financially and return the loaned
securities at a time when the collateral is insufficient to replace the full
amount of the loan. In order to minimize this risk, each Fund will make loans of
securities only to firms determined by its investment adviser (under the
supervision of the Board of Trustees) to be creditworthy.

SHORT-TERM MONEY MARKET INSTRUMENTS
    
All of the Funds may, to varying degrees, invest in short-term money market
instruments, including repurchase agreements, and when-issued and delayed-
delivery securities. A repurchase agreement is a transaction in which a Fund
buys a security at one price and simultaneously agrees to sell that same
security back to the original owner at a higher price. Each Fund's investment
adviser (under the supervision of the Board of Trustees) reviews the
creditworthiness of the other party to the agreement and must find it
satisfactory before engaging in a repurchase agreement. In the event of the
bankruptcy of the other party, the Fund could experience delays in recovering
its money, may realize only a partial recovery or even no recovery, and may also
incur disposition costs. When-issued and delayed delivery securities are
discussed in "Investment Techniques" in the SAI.     

FOREIGN INVESTMENTS

Investing in the securities of companies organized outside the United States or
of companies whose securities are principally traded outside the United States
("foreign issuers") or investments in securities denominated or quoted in
foreign currency ("non-dollar securities") involves certain special
considerations, including those set forth below, which are not typically
associated with investing in securities of domestic issuers or U.S. dollar
denominated securities.
    
Each of the Large Cap Equity Index and International Equity Index Funds may
invest in non-dollar securities and the securities of foreign issuers
(collectively, "foreign investments"). These Funds will generally not
concentrate their investments in any particular foreign country, except to the
extent that the Fund's benchmark index concentrates in such foreign country. The
Large Cap Equity Index Fund may invest up to 20% of its total assets in foreign
securities. The International Equity Index Fund may invest all of its assets in
non-dollar securities and the securities of foreign issuers.       


                                       
<PAGE>
 
Foreign Investments Generally

Foreign investments may offer potential benefits not available from investments
solely in securities of domestic issuers. Such benefits may include the
opportunity to invest in foreign issuers that appear to offer better opportunity
for long-term capital appreciation or current earnings than investments in
domestic issuers, the opportunity to invest in foreign countries with economic
policies or business cycles different from those of the United States and the
opportunity to reduce fluctuations in portfolio value by taking advantage of
foreign securities markets that do not necessarily move in a manner parallel to
U.S. markets.
    
Making foreign investments involves significant risks that are not typically
associated with investing in securities of domestic issuers. Such investments
may be affected by changes in currency rates, changes in foreign or U.S. laws or
restrictions applicable to such investments and in exchange control regulations.
For example, a decline in the currency exchange rate may reduce the value of
certain portfolio investments. Many foreign stock markets may have substantially
less volume than, for example, the New York Stock Exchange and securities of
some foreign issuers may be less liquid than securities of comparable domestic
issuers. Commissions and dealer mark-ups on transactions in foreign securities
may be higher than for similar transactions in the U.S. In addition, clearance
and settlement procedures may be different in foreign countries and, in certain
markets, on certain occasions, such procedures have been unable to keep pace
with the volume of securities transactions, thus making it difficult to conduct
such transactions. For example, delays in settlement could result in temporary
periods when a portion of the assets of a Fund are uninvested and no return is
earned thereon. The inability of a Fund to make intended investments due to
settlement problems could cause it to miss attractive investment opportunities.
Inability to dispose of portfolio securities or other investments due to
settlement problems could result either in losses to a Fund due to subsequent
declines in value of the portfolio investment or, if the Fund has entered into a
contract to sell the investment, could result in possible liability for the 
Fund.      

Foreign issuers are not generally subject to uniform accounting, auditing and
financial reporting standards comparable to those applicable to domestic
companies. There may be less publicly available information about a foreign
issuer than about a domestic one. In addition, there is generally less
government regulation of stock exchanges, brokers, and listed and unlisted
issuers in foreign countries than in the United States. Furthermore, with
respect to certain foreign countries, there is a possibility of expropriation or
confiscatory taxation, imposition of withholding taxes on dividend or interest
payments, limitations on the removal of portfolios or other assets of the Fund,
or political or social instability or diplomatic 


                                       
<PAGE>
 
developments which could affect investments in those countries. Individual
foreign economies also may differ favorably or unfavorably from the United
States economy in such respects as growth of gross national product, rate of
inflation, capital reinvestment, resource self-sufficiency and balance of
payments position.

For more information on foreign investments, see "Foreign Investments" in the
SAI.

Investments in ADRS, EDRS and GDRS

Many securities of foreign issuers are represented by sponsored or unsponsored
American depository receipts ("ADRs"), European depository receipts ("EDRs"),
and global depository receipts ("GDRs"). ADRs are receipts typically issued by a
U.S. bank or trust company which evidence ownership of underlying securities of
foreign corporate issuers. EDRs and GDRs are receipts issued by non-U.S.
financial institutions evidencing arrangements similar to ADRs. Generally, ADRs
are in registered form and are designed for trading in U.S. markets while EDRs
are in bearer form and are designed for trading in European securities markets.
GDRs are issued in either registered or bearer form and are designed for trading
on a global basis.
    
The Large Cap Equity Index Fund may invest in ADRs and the International Equity
Index Fund may invest in ADRs, EDRs and GDRs. ADRs represent the right to
receive securities of foreign issuers deposited in a domestic bank or a foreign
correspondent bank. Prices of ADRs are quoted in U.S. dollars, and ADRs are
traded in the U.S. on exchanges or over-the-counter and are sponsored and issued
by domestic banks. ADRs do not eliminate all the risk inherent in investing in
the securities of foreign issuers. To the extent that a Fund acquires ADRs
through banks which do not have a contractual relationship with the foreign
issuer of the security underlying the ADR to issue and service such ADRs, there
may be an increased possibility that the Fund would not become aware of and be
able to respond to corporate actions such as stock splits or rights offerings
involving the foreign issuer in a timely manner. In addition, the lack of
information may result in inefficiencies in the valuation of such instruments.
However, by investing in ADRs rather than directly in the stock of foreign
issuers, a Fund will avoid currency risks during the settlement period for
either purchases or sales. In general, there is a large, liquid market in the
U.S. for ADRs quoted on a national securities exchange or the NASD's national
market system. The information available for ADRs is subject to the accounting,
auditing and financial reporting standards of the domestic market or exchange on
which they are traded, which standards are more uniform and more exacting than
those to which many foreign issuers may be subject.      

EDRs and GDRs are receipts evidencing an arrangement with a non-U.S. bank
similar to that for ADRs and are designed for use in non-U.S. securities
markets. EDRs and GDRs are not necessarily quoted in the same currency as the
underlying security.

Forward Currency Contracts

    
As described above, the International Equity Index Fund may enter into foreign
currency forward and foreign currency futures contracts. Such contracts are
subject to special risks. For example, contracts to sell foreign currency could
limit any potential gain which might be realized by the Fund if the value of the
hedged currency increased. In addition, forward contracts are subject to the
risk that the counterparty to such contract will default on its obligations.
Since a forward foreign currency exchange contract is not guaranteed by an
exchange or clearinghouse, a default on the contract would deprive the Fund of
unrealized profits, transaction costs or the benefits of a currency hedge or
force the Fund to cover its purchase or sale commitments, if any, at the current
market price.      

                                       
<PAGE>
 
STOCK INDEX FUTURES CONTRACTS AND OPTIONS ON SUCH CONTRACTS

    
Each equity index Fund may purchase and sell futures contracts on its benchmark
stock index or a similar stock index as a way to gain exposure to the securities
in the benchmark index or to simulate full investment in the underlying
benchmark equities. A stock index futures contract is a contract to buy or sell
a specified amount of securities comprising the index to which it relates at a
future time for a fixed price.     

An equity index Fund may write covered call options and purchase options on
futures contracts to offset futures contracts held by the Fund that become
illiquid. An option to sell a financial futures contract gives the purchaser
thereof the right to sell a position in the underlying futures contract, and,
therefore, can serve the same function as selling the futures contract directly.
When used to offset a futures contract already owned by a Fund, an option can
effectively close out the Fund's position with regard to that futures contract.

The Stock and Bond Balanced Fund may indirectly hold these types of securities
by virtue of its investment in the Large Cap Equity Index Fund.

None of the equity index Funds will enter into any financial futures contract or
purchase any option thereon, if, immediately thereafter, the total amount of its
assets required to be on deposit as margin to secure its obligations under open
futures contracts, plus the amount of premiums paid by the Fund for outstanding
options to purchase futures contracts, would exceed 5% of the market value of
the Fund's total assets.

The use of futures contracts by these Funds entails certain risks, including but
not limited to the following: no assurance that futures contract transactions
can be offset at favorable prices; possible reduction of a Fund's income due to
their use; possible reduction in value of the futures contract; possible lack of
liquidity due to daily limits on price fluctuations; imperfect correlation
between the futures contract and the securities held in the Fund or the
securities comprising the benchmark index; and potential losses in excess of the
amount initially invested in the futures contracts themselves. The use of
futures contracts and options on futures contracts requires special skills in
addition to those needed to select portfolio securities. A further discussion of
futures contracts and their associated risks is contained in the SAI.

RESTRICTED SECURITIES AND ILLIQUID INVESTMENTS

    
Each Fund's adviser is responsible for determining the liquidity of investments
held by that Fund. Investments may be illiquid because of the absence of a
trading market, making it difficult to value them or dispose of them promptly at
an acceptable price. The Large Cap Equity Index, Small Cap Equity Index,
International Equity Index, and Money Market Funds will each not purchase or
otherwise acquire any investment if, as a result, more than 15% (10% in the case
of the Money Market Fund) of its net assets (taken at current value) would be
invested in instruments that are illiquid, except as described below.     
                                       
<PAGE>
 
          

Illiquid investments include most repurchase agreements maturing in more than
seven days, currency swaps, time deposits with a notice or demand period of more
than seven days, certain over-the-counter option contracts (and segregated
assets used to cover such options), participation interests in loans, and
restricted securities. A restricted security is one that has a contractual
restriction on resale or cannot be resold publicly until it is registered under
the Securities Act of 1933.

    
The foregoing illiquid security investment restrictions do not apply to
purchases of restricted securities eligible for sale to qualified institutional
purchasers in reliance upon Rule 144A under the Securities Act of 1933 that are
determined to be liquid by the Trust's Board of Trustees or by a Fund's
investment adviser under board-approved procedures. Such guidelines would take
into account trading activity for such securities and the availability of
reliable pricing information, among other factors. To the extent that qualified
institutional buyers become for a time uninterested in purchasing these
restricted securities, a Fund's holdings of those securities may become
illiquid. The foregoing investment restrictions also do not apply to purchases
by the International Equity Index Fund of securities of foreign issuers offered
and sold outside the United States in reliance upon the exemption from
registration provided by Regulation S under the Securities Act of 1933.      

BORROWING

    
From time to time, each Fund may borrow money from a bank or through reverse
repurchase agreements in amounts up to 33 1/3% of its total assets (including
the amount borrowed). Each Fund may also borrow up to an additional 5% of its
total assets (including the amount borrowed), but only for temporary purposes
(e.g., to facilitate distributions to shareholders or to meet redemption
requests prior to the settlement of securities already sold or in the process of
being sold by the Fund). Each Fund may also obtain such short-term credits as
may be necessary for clearance of purchases and sales of portfolio securities.
    
INVESTMENTS IN SECURITIES OF SMALL CAPITALIZATION ISSUERS
    
The Small Cap and International Equity Index Funds may invest in securities
issued by small capitalization companies. Some of these companies often do not
have the financial strength needed to do well in difficult times.      


                                       
<PAGE>
 
Also, they often sell limited numbers of products, which can make it harder for
them to compete with medium and large companies. However, because they are
small, their stock prices may fluctuate more over the short-term, but they have
more potential to grow. This means their stock value may offer greater potential
for appreciation.

INVESTMENTS IN OTHER INVESTMENT COMPANIES

Each Fund other than the Stock and Bond Balanced Fund may invest up to 5% of its
total assets in the securities of any single investment company and up to 10% of
its total assets in the securities of other investment companies in the
aggregate. However, no Fund (other than the Stock and Bond Balanced Fund) may
hold more than 3% of the total outstanding voting stock of any single investment
company.

The Stock and Bond Balanced Fund may invest 100% of its total assets in the
securities of other investment companies.

                            PERFORMANCE INFORMATION

From time to time the Trust may publish average annual total return figures for
one or more of the Funds in advertisements and communications to shareholders or
sales literature. Average annual total return is determined by computing the
annual percentage change in value of $1,000 invested for specified periods
ending with the most recent calendar quarter, assuming reinvestment of all
dividends and distributions at net asset value. The average annual total return
calculation assumes a complete redemption of the investment at the end of the
relevant period.

The Trust also may from time to time publish year-by-year total return,
cumulative total return and yield information for the Funds in advertisements,
communications to shareholders or sales literature. These may be provided for
various specified periods by means of quotations, charts, graphs or schedules.
Year-by-year total return and cumulative total return for a specified period are
each derived by calculating the percentage rate required to make a $1,000
investment in a Fund (assuming all distributions are reinvested) at the
beginning of such period equal to the actual total value of such investment at
the end of such period.
    
Yield is computed by dividing net investment income earned during a recent 30
day period by the product of the average daily number of shares outstanding and
entitled to receive dividends during the period and the price per share on the
last day of the relevant period. The results are compounded on a bond equivalent
(semi-annual) basis and then annualized. Net investment income is equal to the
dividends and interest earned during the period, reduced by accrued expenses for
the period. The calculation of net investment income for these purposes may
differ from the net investment income determined for accounting purposes.      

                                       
<PAGE>
 
In addition, the Trust may from time to time publish performance of its Funds
relative to certain performance rankings and indices.

The investment results of the Funds will fluctuate over time and any
presentation of investment results for any prior period should not be considered
a representation of what an investment may earn or what a Fund's performance may
be in any future period.

                       DETERMINATION OF NET ASSET VALUE
    
The net asset value of each Fund is determined as of the time of the close of
trading on the New York Stock Exchange, (currently at 4:00 PM, New York City
time) on each day when the New York Stock Exchange is open except as noted
below. The New York Stock Exchange is scheduled to be open Monday through Friday
throughout the year, except for certain federal and other holidays. The net
asset value of each Fund will not be calculated on the Friday following
Thanksgiving or on December 26, 1997. The net asset value of a Fund is
determined by adding the values of all securities, cash and other assets
(including accrued but uncollected interest and dividends) of that Fund and
subtracting all liabilities (including accrued expenses but excluding capital
and surplus). The net asset value of a share is determined by dividing the net
asset value of a Fund by the number of outstanding shares of that Fund. Except
for the securities and assets of the Money Market Fund and short-term debt
securities with remaining maturities of 60 days or less other than U.S. Treasury
bills, portfolio securities generally will be valued based upon their market
value. All of the securities and assets of the Money Market Fund and short-term
debt securities having remaining maturities of 60 days or less, other than U.S. 
Treasury bills, held by any of the other Funds are valued by the amortized cost
method, which approximates market value. Expenses, including the investment
advisory fee payable to SFIM, are accrued daily.    

The net asset value per share of the Stock and Bond Balanced Fund will be based,
in part, on the net asset value per share of each of the underlying Funds in
which it invests. Thus, while the net asset value per share of the Stock and
Bond Balanced Fund will be determined as described above, the pricing of the
Stock and Bond Balanced Fund's securities cannot occur until the net asset
values per share of the underlying Funds are determined.

                  OFFERING, PURCHASE AND REDEMPTION OF SHARES
    
Pursuant to an underwriting agreement, SFIM acts without remuneration as the
Trust's underwriter in the distribution of the shares of each Fund. See
"Investment Adviser" and "Service Providers" in this prospectus for more
information.      

Shares of the Funds are sold in a continuous offering and are authorized to be
offered to the Accounts to support the Contracts. Net purchase payments under
the Contracts are placed in one or more subaccounts of the Accounts and the
assets of each subaccount are invested in the 

                                       
<PAGE>
 
     
shares of the Fund corresponding to that subaccount. The Accounts purchase and
redeem shares of the Funds for their subaccounts at net asset value without 
sales or redemption charges.       

For each day on which a Fund's net asset value is calculated, the Accounts
transmit to the Trust any orders to purchase or redeem shares of the Fund(s)
based on the purchase payments, redemption (surrender) requests, and transfer
requests from Contract owners, annuitants and beneficiaries that have been
processed that day. The Accounts purchase and redeem shares of each Fund at the
Fund's net asset value per share calculated as of that same day although such
purchases and redemptions may be executed the next morning.

Please refer to the separate prospectuses for the Contracts and the Accounts for
a more detailed description of the procedures whereby a Contract owner,
annuitant or beneficiary may allocate his or her interest in the Account to a
subaccount using the shares of one of the Funds as an underlying investment
medium.

In the future, the Trust may offer shares of one or more of the Funds (including
new funds that might be added to the Trust) to other registered or unregistered
separate accounts of State Farm or its life insurance company affiliates to
support variable annuity or variable life insurance contracts (other than the
Contracts). Likewise, the Trust may also, in the future and subject to obtaining
required regulatory approvals, offer shares of one or more of the Funds directly
to qualified pension and retirement plans.
    
Because shares of the Funds are offered to Accounts supporting variable annuity
Contracts and Accounts supporting variable life insurance Contracts, a potential
for certain conflicts may exist between the interests of owners of variable
annuity Contracts and owners of variable life insurance Contracts. Likewise, in
the event that shares of any Fund are offered to qualified pension and
retirement plans, a potential for certain conflicts may exist between the
interests of variable annuity contract owners, variable life insurance contract
owners and plan participants. The Trust does not currently foresee any
disadvantage to owners of either variable annuity Contracts or variable life
insurance Contracts arising from the fact that shares of any Fund might be held
by such entities. The Trust's Board of Trustees, however, will monitor the Funds
in order to identify any material irreconcilable conflicts of interest which may
possibly arise, and to determine what action, if any, should be taken in
response to such conflicts.     

                      DIVIDENDS, DISTRIBUTIONS AND TAXES

DIVIDENDS AND DISTRIBUTIONS

It is the Trust's intention to distribute, as dividends, substantially all of
the net investment income, if any, from each of the Funds. All dividends of a
Fund are subsequently reinvested 

                                       
<PAGE>
 
in additional shares of that Fund at net asset value, subject to redemption
rights discussed above.
    
The Bond Fund and the Money Market Fund intend to declare dividends from their
net investment income every day. Each of these Funds will distribute such 
dividends quarterly by reinvesting them in additional Fund shares at net asset
value.     
 
TAXES
    
General Tax Information     
    
The Trust intends that each of the Funds will qualify as a regulated investment
company under Subchapter M of Chapter 1 of the Internal Revenue Code of 1986
(the "Code"). If each of the Funds qualifies as a regulated investment company
and the Trust distributes substantially all of its net income and gains to its
shareholders (which it intends to do), then under the provisions of 
Subchapter M, the Trust should have little or no income taxable to it under the
Code.     
    
Each Fund of the Trust must meet several requirements to maintain its status as
a regulated investment company. These requirements include the following: (1) at
least 90% of the Fund's gross income must be derived from dividends, interest,
payments with respect to securities loaned, and gains from the sale or
disposition of securities; and (2) at the close of each quarter of the Fund's
taxable year, (a) at least 50% of the value of the Fund's total assets must
consist of cash, U.S. Government securities and other securities (no more than
5% of the value of the Fund may consist of such other securities of any one
issuer, and the Fund must not hold more than 10% of the outstanding voting stock
of any issuer), and (b) the Fund must not invest more than 25% of the value of
its total assets in the securities of any one issuer (other than U.S. Government
securities).        
    
In order to maintain the qualification of a Fund's status as a regulated
investment company, the Trust may, in its business judgment, restrict a Fund's
ability to enter into stock index futures contracts or options on such futures 
contracts or engage in short-term trading and transactions in securities
(including stock index futures contracts and options on such futures contracts).
For the same reason, the Trust may, in its business judgment, require a Fund to
defer the closing out of a contract beyond the time when it might otherwise be
advantageous to do so.       

Each of the Funds also intends to comply with section 817(h) of the Code and the
regulations issued thereunder, which impose certain investment diversification
requirements on life insurance companies' separate accounts (such as the
Accounts) that are used to fund benefits under variable life insurance and
variable annuity contracts. These requirements are in 

                                       
<PAGE>
 
addition to the requirements of subchapter M and of the Investment Company Act
of 1940, and may affect the securities in which a Fund may invest. In order to
comply with the current or future requirements of section 817(h) (or related
provisions of the Code), the Trust may be required, e.g., to alter the
investment objectives of one or more of the Funds. No such change of investment
objectives will take place without notice to the shareholders of an affected
Fund, the approval of a majority of the outstanding voting shares, and the
approval of the Securities and Exchange Commission, to the extent legally
required.
    
Taxation of Foreign Investments     

Funds investing in foreign securities or currencies may be required to pay
withholding or other taxes to foreign governments. Foreign tax withholding from
dividends and interest, if any, is generally at a rate between 10% and 35%. The
investment yield of any Fund that invests in foreign securities or currencies
will be reduced by these foreign taxes. Shareholders will bear the cost of any
foreign tax withholding, but may not be able to claim a foreign tax credit or
deduction for these foreign taxes. Funds investing in securities of passive
foreign investment companies may be subject to U.S. Federal income taxes and
interest charges, and the investment yield of a Fund making such investments
will be reduced by these taxes and interest charges. Shareholders will bear the
cost of these taxes and interest charges, but will not be able to claim a
deduction for these amounts.
    
Additional Tax Considerations     

If a Fund failed to qualify as a regulated investment company, owners of
variable life insurance and annuity contracts based on the Fund (1) might be
taxed currently on the investment earnings under their contracts and thereby
lose the benefit of tax deferral, and (2) the Fund might incur additional taxes.
In addition, if a Fund failed to comply with the diversification requirements of
section 817(h) of the Code and the regulations thereunder, owners of variable
life insurance and annuity contracts based on the Fund would be taxed on the
investment earnings under their contracts and thereby lose the benefit of tax
deferral. Accordingly, compliance with the above rules is carefully monitored by
the Funds' investment advisers and it is intended that each Fund will comply
with these rules as they exist or as they may be modified from time to time.
Compliance with the tax requirements described above may result in a reduction
in the return under a Fund, since, to comply with the above rules, the
investments utilized (and the time at which such investments are entered into
and closed out) may be different from what the Fund's investment adviser might
otherwise believe to be desirable.

It is not feasible to comment on all of the federal tax consequences concerning
the Funds. Since the shareholders of the Funds are currently limited to the
Accounts, no further discussion of those consequences is included herein. For
information concerning the federal 

                                       
<PAGE>
 
income tax consequences to the owners of variable life insurance and annuity
contracts, see the prospectuses for the contracts.

                            MANAGEMENT OF THE TRUST

BOARD OF TRUSTEES
    
The Trust has a Board of Trustees, the members of which are elected by the
shareholders.  The Trustees are responsible for the overall management of the
Trust and their duties include reviewing the results of each of the Funds,
monitoring investment activities and techniques, and receiving and acting upon
future plans for the Trust.     

It is possible that the interests of the Stock and Bond Balanced Fund could
diverge from the interests of one or more of the underlying Funds in which it
invests.  If such interests were ever to become divergent, it is possible that a
conflict of interest could arise and affect how the Trustees and officers
fulfill their fiduciary duties to each Fund.  The Trustees believe they have
structured each Fund to avoid these concerns.  However, conceivably, a situation
could occur where proper action for the Stock and Bond Balanced Fund could be
adverse to the interests of an underlying Fund, or the reverse could occur.  If
such a possibility arises, the affected Funds' investment adviser(s) and the
Trustees and officers of the Trust will carefully analyze the situation and take
all steps they believe reasonable to minimize and, where possible, eliminate the
potential conflict.  Moreover, close and continuous monitoring will be exercised
to avoid, insofar as possible, these concerns.

INVESTMENT ADVISER
    
Pursuant to an investment advisory and management services agreement with the
Trust and subject to the authority of the Trust's Board of Trustees, SFIM serves
as the Trust's investment adviser and conducts the business and affairs of the
Trust.  It is registered under the Investment Advisers Act of 1940 and its
principal office is located at One State Farm Plaza, Bloomington, Illinois
61710-0001.  SFIM is wholly-owned by State Farm Mutual Automobile Insurance
Company ("SFMAIC").  Pursuant to a separate service agreement among SFMAIC, SFIM
and the Trust, SFMAIC provides SFIM with certain personnel, services and
facilities to enable SFIM to perform its obligations to the Trust.     

Since its inception in 1967, SFIM's sole business has been to act as investment
adviser, principal underwriter, transfer agent and dividend disbursing agent for
the State Farm mutual funds.  SFIM also provides all executive, administrative,
clerical and other personnel necessary to operate the Trust and pays the
salaries and other costs of employing all these persons.  SFIM furnishes the
Trust with office space, facilities, and equipment and pays the day-to-day 
expenses related to the operating and maintenance of such office space, 
facilities

                                       
<PAGE>
 
and equipment. All expenses incurred in the organization of the Trust or of any
new Funds of the Trust, including legal and accounting expenses and certain
costs of registering securities of the Trust under federal and state securities
laws, are also paid by SFIM.
    
The Trust is responsible for payment of all expenses it may incur in its
operation and all of its general administrative expenses except those expressly
assumed by SFIM as described in the preceding paragraphs. These include (by way
of description and not of limitation), any share redemption expenses, expenses
of portfolio transactions, shareholder servicing costs, pricing costs, interest
on borrowings by the Trust, charges of the custodians and transfer agent, if
any, cost of auditing services, non-interested Trustees' fees, all taxes and
fees, investment advisory fees (other than subadvisory fees), certain insurance
premiums, cost of maintenance of corporate existence, investor services
(including allocable personnel and telephone expenses), costs of printing and
mailing updated Trust prospectuses to shareholders and contractholders,
preparing, printing and mailing proxy statements and shareholder reports to
shareholders and contractholders, the cost of paying dividends and capital gains
distributions, costs of Trustee and shareholder meetings, dues to trade
organizations, and any extraordinary expenses, including litigation costs in
legal actions involving the Trust, or costs related to indemnification of
Trustees, officers and employees of the Trust. SFIM reimburses SFMAIC for such
costs, direct and indirect, as are fairly attributable to the services performed
and the facilities provided by SFMAIC under the separate service agreement.
Accordingly, the Trust makes no payment to SFMAIC under the service agreement.
     
The Trust pays SFIM monthly compensation in the form of an investment advisory
fee.  The fee is based upon average daily net assets and is accrued daily and
paid to SFIM quarterly at the following annual rates for each of the Funds:

     Large Cap Equity Index        .26% of net assets
     Small Cap Equity Index        .40% of net assets
     International Equity Index    .55% of net assets
     Bond                          .50% of net assets
     Money Market                  .40% of net assets
     Stock and Bond Balanced       None
    
SFIM has agreed not to be paid an investment advisory fee for performing its
services for the Stock and Bond Balanced Fund and has agreed to bear any other
expenses incurred by the Stock and Bond Balanced Fund. (This expense limitation 
arrangement is voluntary and may be eliminated by SFIM at any time.) However,
SFIM will receive investment advisory fees from managing the underlying Funds in
which the Stock and Bond Balanced Fund invests.    
    
With respect to each of the Funds other than the Stock and Bond Balanced Fund 
and the International Equity Index Fund, SFIM has agreed to bear the expenses
incurred by the Fund, other than the investment advisory fee, that exceed .10%
of such Fund's average daily net assets. With respect to the International
Equity Index Fund, SFIM has agreed to bear the expenses incurred by the Fund,
other than the investment advisory fee, that exceed .20% of the Fund's average
daily net assets. These expense limitation arrangements are voluntary and may be
eliminated by SFIM at any time.

INVESTMENT SUB-ADVISER
    
SFIM has engaged BGFA as the investment sub-adviser to provide day-to-day
portfolio management for the Large Cap, Small Cap, and International Equity
Index Funds.  BGFA was created by the reorganization of Wells Fargo Nikko
Investment Advisors with and into an affiliate of Wells Fargo Institutional
Trust Company, N.A.  BGFA is an indirect subsidiary of Barclays Bank PLC and is
located at 45 Fremont Street, San Francisco, California 94105.  As of April 30,
1997, BGFA and its affiliates provided investment advisory services for over
$429 billion of assets.      
    
BGFA determines which securities to buy and sell for each of these Funds,
selects the brokers and dealers to effect the transactions, and negotiates
commissions.  For its services, SFIM pays BGFA an investment sub-advisory fee 
equal to a percentage of the average daily net assets of each index Fund at the 
rates set forth below less certain credits also described below. The fee is
accrued daily and paid to BGFA quarterly. The rates upon which the fee is based
are as follows:     
    
   Large Cap Equity Index Fund     .15% of the next $50,000,000 of net assets 
   ---------------------------     .10% of the next $50,000,000 of net assets 
                                   .08% thereafter                            
                                                                                
    
   Small Cap Equity Index Fund     .20% of the next $50,000,000 of net assets   
   ---------------------------     .15% of the next $50,000,000 of net assets  
                                   .12% thereafter                             
                                                                               
    
   International Equity Index Fund .35% of the next $50,000,000 of net assets  
   ------------------------------- .30% of the next $50,000,000 of net assets  
                                   .20% thereafter                             
    
The quarterly fee payable by SFIM to BGFA with respect to each index Fund will
be reduced by certain credits. The fee with respect to the Large Cap Equity,
Index Fund and Small Cap Equity Index Fund will be reduced by $875 and $2,875
per quarter, respectively. The fee with respect to the International Equity 
Index Fund will be reduced by $3,750 per quarter and an additional amount based 
upon such Fund's international custody charges.

USE OF CERTAIN BROKERS
 
SFIM or BGFA may use brokerage firms that are affiliated with State Farm or BGFA
to execute portfolio trades for the funds, but only when SFIM or BGFA, as
appropriate, believes that no other firm offers a better combination of quality
execution (i.e., timeliness and completeness), favorable price and value of
research services.     
                            ADDITIONAL INFORMATION

ABOUT THE SHARES

The Trust is currently issuing six series of shares, each representing
beneficial interests in one of the six Funds.  Each share (including fractional
shares) is entitled to one vote for each dollar of net asset value represented
by that share on all matters to which the holder of that share is entitled to
vote.  All shares have equal proportional rights with regard to redemptions,
dividends, distributions, and liquidations with respect to the Fund in which
they represent an interest.  When issued, shares are fully paid and
nonassessable and do not have preemptive or conversion rights or cumulative
voting rights.

CONTRACT OWNER VOTING RIGHTS

With regard to matters for which the Investment Company Act of 1940 requires a
shareholder vote, State Farm, as the legal owner of shares held by the Accounts,
typically votes Trust shares held by the Accounts in accordance with
instructions received from owners of Contracts (or annuitants or beneficiaries
thereunder) having a voting interest in the Accounts.  Each share has one vote
for each dollar of net asset value represented by that share and votes are
counted on an aggregate basis except as to matters where the interests of Funds
differ (such as approval of an investment advisory agreement or a change in the
fundamental investment policies).  In such a case, the voting is on a Fund-by-
Fund basis.  Fractional shares are counted proportionally.  Shares held by
Accounts for which no instructions are received are generally voted by State
Farm for or against any proposition, or in abstention, in the same proportion as
the shares for which instructions have been received.   You should refer to the
separate prospectus, which accompanies this prospectus, describing your Contract
and the Account through which it is offered for more information on your voting
rights.

                    INVESTMENT TECHNIQUES AND RESTRICTIONS

INVESTMENT TECHNIQUES

The objectives, policies, and certain techniques by which the Funds will pursue
their objectives are generally set forth in the Prospectus.  This section is
intended to augment the explanation found in the Prospectus.

The Money Market Fund

    
The Money Market Fund will only invest in instruments denominated in U.S.
dollars that SFIM, under the supervision of the Trust's Board of Trustees,
determines present minimal credit risk and are, at the time of acquisition,
either:      

     1.   rated in one of the two highest rating categories for short-term debt
          obligations assigned by at least two NRSROs, or by only one NRSRO if
          only one NRSRO has issued a rating with respect to the instrument
          ("requisite NRSROs"); or
    
     2.   in the case of an unrated instrument, that SFIM determines, under the
          supervision of the Trust's Board of Trustees, to be of comparable
          quality to the instruments described in paragraph 1 above; or      

     3.   issued by an issuer that has received a rating of the type described
          in paragraph 1 above on other securities that are comparable in
          priority and security to the instrument.

Pursuant to Rule 2a-7 under the Investment Company Act of 1940 (the "Act"),
securities which are rated (or that have been issued by an issuer that has been
rated with respect to a class of short-term debt obligations, or any security
within that class, comparable in priority and quality with such security) in the
highest short-term rating category by at least two NRSROs are designated "First
Tier Securities."  Securities rated in the top two short-term rating categories
by at least two NRSROs, but which are not rated in the highest short-term
category by at least two NRSROs, are designated "Second Tier Securities."
NRSROs are listed in the Prospectus and a description of their ratings are found
in Appendix A herein.

Pursuant to Rule 2a-7, the Money Market Fund may not invest more than 5% of its
assets taken at amortized cost in the securities of any one issuer (except the
U.S. Government, including repurchase agreements collateralized by U.S.
Government securities (defined below)).  The Fund may, however, invest more than
5% of its assets in the First Tier Securities of a single issuer for a period of
up to three business days after the purchase thereof, although the Fund may not
make more than one such investment at any time. 

                                     
<PAGE>
 
Further, the Fund will not invest more than the greater of (i) 1% of its total
assets; or (ii) one million dollars in the securities of a single issuer that
were Second Tier Securities when acquired by the Fund.  In addition, the Fund
may not invest more than 5% of its total assets in securities which were Second
Tier Securities when acquired.

The foregoing policies are more restrictive than the fundamental investment
restriction number 1 set forth below, which would give the Fund the ability to
invest, with respect to 25% of its assets, more than 5% of its assets in any one
issuer.  The Fund will operate in accordance with these policies to comply with
Rule 2a-7.

When-issued And Delayed Delivery Securities
    
From time to time, in the ordinary course of business, each Fund may purchase
securities on a when-issued basis or delayed-delivery basis, i.e., delivery and
payment can take place a month or more after the date of the transaction.  The
securities so purchased are subject to market fluctuation, and no interest
accrues to the purchaser during this period.  At the time a Fund makes the
commitment to purchase securities on a when-issued or delayed-delivery basis,
the Trust will record the transaction and thereafter reflect the value, each
day, of such security in determining the net asset value of that Fund.  At the
time of delivery of the securities, the value may be more or less than the
purchase price. Each Fund will also segregate cash or cash equivalents or other
liquid portfolio securities equal in value, marked to market on a daily basis,
to commitments for such when-issued or delayed-delivery securities. As a general
matter each Fund will hold less than 5% of its total assets in commitments to
purchase securities on a delayed-delivery or when-issued basis and will not,
under any circumstances, purchase securities on a when-issued or delayed-
delivery basis if, as a result, more than 10% of the net assets of the Fund
would be so invested.     

Loans Of Portfolio Securities

    
Each Fund may from time to time lend securities that it holds to brokers,
dealers and financial institutions, up to a maximum of 33% of the total value of
each Fund's assets.  This percentage may not be increased without approval of a
majority of the outstanding voting securities of the respective Funds.  See
"Fundamental Restrictions" on page 10.  Such loans will be secured by
collateral in the form of cash or United States Treasury securities, or other
liquid securities as permitted by the Securities and Exchange Commission
("Commission"), which at all times while the loan is outstanding, will be
maintained in an amount at least equal to the current market value of the loaned
securities.  The Fund making the loan will continue to receive interest and
dividends on the loaned securities during the term of the loan, and, in
addition, will receive a fee from the borrower or interest earned from the
investment of cash collateral in short-term securities.  The Fund will also
receive any gain or loss in the market       


                                     
<PAGE>
 
value of loaned securities and of securities in which cash collateral is
invested during the term of the loan.

    
The right to terminate a loan of securities, subject to appropriate notice, will
be given to either party.  When a loan is terminated, the borrower will return
the loaned securities to the appropriate Fund.  No Fund will have the right to
vote securities on loan, but each would terminate a loan and regain the right to
vote if the Trust's Board of Trustees deems it to be necessary in a particular
instance.      

For tax purposes, the dividends, interest and other distributions which a Fund
receives on loaned securities may be treated as other than qualified income for
the 90% test discussed under "Taxes" in the Prospectus.  Each Fund intends to
lend portfolio securities only to the extent that this activity does not
jeopardize its, or the Trust's, status as a regulated investment company under
the Internal Revenue Code of 1986 (the "Code").

    
The primary risk involved in lending securities is that the borrower will fail
financially and return the loaned securities at a time when the collateral is
insufficient to replace the full amount of the loan.  The borrower would be
liable for the shortage, but the Fund making the loan would be an unsecured
creditor with respect to such shortage and might not be able to recover all or
any of it.  In order to minimize this risk, each Fund will make loans of
securities only to firms SFIM or, when appropriate, BGFA (under the supervision
of the Board of Trustees) deems creditworthy.      

Convertible Securities

The Bond Fund may invest up to 20% of its total assets in convertible
securities.  Convertible securities may include corporate notes or preferred
stock but are ordinarily a long-term debt obligation of the issuer convertible
at a stated exchange rate into common stock of the issuer. As with all debt
securities, the market value of convertible securities tends to decline as
interest rates increase and, conversely, to increase as interest rates decline.
Convertible securities generally offer lower interest or dividend yields than
non-convertible securities of similar quality.  However, when the market price
of the common stock underlying a convertible security exceeds the conversion
price, the price of the convertible security tends to reflect the value of the
underlying common stock.  As the market price of the underlying common stock
declines, the convertible security tends to trade increasingly on a yield basis,
and thus may not depreciate to the same extent as the underlying common stock.
Convertible securities generally rank senior to common stocks in an issuer's
capital structure and are consequently of higher quality and entail less risk of
declines in market value than the issuer's common stock.  However, the extent to
which such risk is reduced depends in large measure upon the degree to which the
convertible security sells above its value as a fixed-income security.  In
evaluating a convertible security, SFIM usually gives primary emphasis to the

                                     
<PAGE>
 
attractiveness of the underlying common stock.  The convertible debt securities
in which the Bond Fund may invest are subject to the same rating criteria as its
investment in non-convertible debt securities.

Because the Stock and Bond Balanced Fund invests a portion of its assets in the
Bond Fund, the Stock and Bond Balanced Fund is subject to the same risks with
regard to investments in convertible securities.
    
Warrants     

The Bond Fund and, indirectly, the Stock and Bond Balanced Fund, may invest in
warrants or rights (other than those acquired in units or attached to other
securities) which entitle the purchaser to buy equity securities at a specific
price for a specific period of time.  Warrants and rights have no voting rights,
receive no dividends and have no rights with respect to the assets of the
issuer.  The Bond Fund may retain up to 10% of the value of its total assets in
common stocks acquired by the exercise of warrants attached to debt securities.
    
U.S. Government Securities     

All of the Funds may purchase securities issued or guaranteed as to principal
and interest by the U.S. Government, its agencies, authorities or
instrumentalities ("U.S. Government Securities").  Some U.S. Government
Securities, such as Treasury bills, notes and bonds, which differ only in their
interest rates, maturities and times of issuance, are supported by the full
faith and credit of the United States.  Others, such as obligations issued or
guaranteed by U.S. Government agencies, authorities or instrumentalities are
supported either by (a) the full faith and credit of the U.S. Government (such
as securities of the Small Business Administration), (b) the right of the issuer
to borrow from the Treasury (such as securities of the Federal Home Loan Banks),
(c) the discretionary authority of the U.S. Government to purchase the agency's
obligations (such as securities of the Federal National Mortgage Association),
or (d) only the credit of the issuer.  No assurance can be given that the U.S.
Government will provide financial support to U.S. Government agencies,
authorities or instrumentalities in the future.  U.S. Government Securities may
also include zero coupon bonds.

Securities guaranteed as to principal and interest by the U.S. Government, its
agencies, authorities or instrumentalities are considered to include (a)
securities for which the payment of principal and interest is backed by a
guarantee of or an irrevocable letter of credit issued by the U.S. Government,
its agencies, authorities or instrumentalities and (b) participation in loans
made to foreign governments or their agencies that are so guaranteed.  The
secondary market for certain of these participations is limited.  Such
participations may therefore be regarded as illiquid.

Foreign Investments     

Investing in the securities of companies organized outside the United States or
of companies whose securities are principally traded outside the United States
("foreign issuers") or investments in securities denominated or quoted in
foreign currency ("non-dollar securities") involves certain special
considerations, including those set forth below, which are not typically
associated with investing in securities of domestic issuers or U.S. dollar
denominated securities.

Each of the Large Cap and International Equity Index Funds may invest in non-
dollar securities and the securities of foreign issuers (collectively, "foreign
investments").

Investments in foreign issuers may involve currencies of foreign countries.
Since a Fund may temporarily hold funds in bank deposits in foreign currencies
during completion of investment programs, it may be subject to currency exposure
independent of its securities positions and may be affected favorably or
unfavorably by changes in currency rates and in exchange control regulations.
Accordingly, it may incur costs in connection with conversions between various
currencies.

Since foreign issuers are not subject to uniform accounting, auditing and
financial reporting standards, practices and requirements comparable to those
applicable to U.S. issuers, there may be less publicly available information
about a foreign issuer than about a domestic issuer. Volume and liquidity in
most foreign securities markets are less than in the United States and
securities of many foreign issuers are less liquid and more volatile than
securities of comparable domestic issuers.  Fixed commissions on foreign
securities exchanges are generally higher than negotiated commissions on U.S.
exchanges, although a Fund making investments in securities of foreign issuers
will endeavor to achieve the most favorable net results on its portfolio
transactions.  There is generally less government supervision and regulation of
securities exchanges, brokers, dealers and listed and unlisted issuers than in
the United States.  Mail service between the United States and foreign countries
may be slower or less reliable than within the United States, thus increasing
the risk of delayed settlements of portfolio transactions or loss of
certificates for portfolio securities.

Foreign securities markets also have different clearance and settlement
procedures, and in certain markets there have been times when settlements have
been unable to keep pace with the volume of transactions, making it difficult to
conduct such transactions.  Such delays in settlement could result in temporary
periods when a portion of the assets of a Fund making an investment on such a
market are uninvested and no return is earned on such assets.  The inability of
such a Fund to make intended security purchases due to settlement problems could
cause the Fund to miss attractive investment opportunities.  Moreover, inability
to dispose of portfolio investments due to settlement problems could result
either in losses to the Fund due 

                                     
<PAGE>
 
     
to subsequent declines in value of the portfolio securities or, if the Fund has
entered into a contract to sell the securities, could result in possible
liability for the Fund. In addition, with respect to certain foreign countries,
there is the possibility of expropriation or confiscatory taxation, political or
social instability, or diplomatic developments which could affect a Fund's
investments in those countries. Also, individual foreign economies may differ
favorably or unfavorably from the U.S. economy in such respects as growth of
gross national product, rate of inflation, capital reinvestment, resource self-
sufficiency and balance of payments position.      
    
Financial Futures Contracts     

The Large Cap, Small Cap, and International Equity Index Funds and, indirectly,
the Stock and Bond Balanced Fund may purchase and sell stock index futures
contracts and options on such futures contracts as described in the Prospectus.
    
Stock index futures contracts bind purchaser and seller to deliver, at a future
date specified in the contract, a cash amount equal to a multiple of the
difference between the value of a specified stock index on that date and the
settlement price specified by the contract.  That is, the seller of the futures
contract must pay and the purchaser would receive a multiple of any excess of
the value of the index over the settlement price, and conversely, the purchaser
must pay and the seller would receive a multiple of any excess of the settlement
price over the value of the index.  A public market currently exists for stock
index futures contracts based on the S&P 500 Index, the New York Stock Exchange
Composite Index, the Value Line Stock Index, and the Major Market Index.  It is
expected that financial instruments related to broad-based indices, in addition
to those for which futures contracts are currently traded, will in the future be
the subject of publicly-traded futures contracts.  Each Fund may purchase and
sell stock index futures contracts on its benchmark index or similar index.     

Positions taken in the futures markets are not normally held until delivery or
cash settlement is required, but instead are liquidated through offsetting
transactions which may result in a gain or a loss.  While futures positions
taken by a Fund are usually liquidated in this manner, a Fund may instead make
or take delivery of underlying securities whenever it appears economically
advantageous to do so.  A clearing organization associated with the relevant
exchange assumes responsibility for closing out transactions and guarantees
that, as between the clearing members of the exchange, the sale and purchase
obligations will be performed with regard to all positions that remain open at
the termination of the contract.

When futures contracts are entered into by a Fund, either as the purchaser or
the seller of such contracts, the Fund is required to deposit with its custodian
in a segregated account in the name of the futures commission merchant ("FCM")
an initial margin of cash or U.S. Treasury bills equaling as much as 5% to 10%
or more of the contract settlement price.  The nature of 

                                     
<PAGE>
 
initial margin requirements in futures transactions differs from traditional
margin payments made in securities transactions in that initial margins for
futures contracts do not involve the borrowing of funds by the customer to
finance the transaction. Instead, a customer's initial margin on a futures
contract represents a good faith deposit securing the customer's contractual
obligations under the futures contract. The initial margin deposit is returned,
assuming these obligations have been met, when the futures contract is
terminated. In addition, subsequent payments to and from the FCM, called
"variation margin," are made on a daily basis as the price of the underlying
security or stock index fluctuates reflecting the change in value in the long
(purchase) or short (sale) positions in the financial futures contract, a
process known as "marking to market."

Futures contracts generally are not entered into to acquire the underlying asset
and generally are not held to term.  Prior to the contract settlement date, a
Fund will normally close all futures positions by entering into an offsetting
transaction which operates to cancel the position held, and which usually
results in a profit or loss.
    
Options On Stock Index Futures Contracts     

The equity index Funds and, indirectly, the Stock and Bond Balanced Fund may
also purchase call and put options and write covered call and put options on
stock index futures contracts of the type which the particular Fund is
authorized to enter into.  Covered put and call options on futures contracts
will be covered in the same manner as covered options on securities and
securities indices.  The Funds may invest in such options for the purpose of
closing out a futures position that has become illiquid.

Options on futures contracts are traded on exchanges that are licensed and
regulated by the CFTC.  A call option on a futures contract gives the purchaser
the right in return for the premium paid, to purchase a futures contract (assume
a "long" position) at a specified exercise price at any time before the option
expires.  A put option gives the purchaser the right, in return for the premium
paid, to sell a futures contract (assume a "short" position), for a specified
exercise price, at any time before the option expires.

Unlike entering into a futures contract itself, purchasing options on futures
contracts allows a buyer to decline to exercise the option, thereby avoiding any
loss beyond forgoing the purchase price (or "premium") paid for the options.
Whether, in order to achieve a particular objective, the Fund enters into a
stock index futures contract, on the one hand, or an option contract on a stock
index futures contract, on the other, will depend on all the circumstances,
including the relative costs, liquidity, availability and capital requirements
of such futures and options contracts.  Each Fund will consider the relative
risks involved, which may be quite different.  These factors, among others, will
be considered in light of market conditions and the particular objective to be
achieved.

Certain Additional Risks Of Futures Contracts And Options On Futures Contracts
     
In addition to the risks described in the Prospectus, the use of stock index
futures contracts and options on such futures contracts may entail the following
risks.  First, although such instruments when used by a Fund are intended to
correlate with the Fund's portfolio securities, in many cases the futures
contracts or options on futures contracts used may be based on stock indices the
components of which are not identical to the portfolio securities owned or
intended to be acquired by the Fund.  Second, due to supply and demand
imbalances and other market factors, the price movements of stock index futures
contracts and options thereon may not necessarily correspond exactly to the
price movements of the stock indices on which such instruments are based.
Accordingly, there is a risk that a Fund's transactions in those instruments
will not in fact offset the impact on the Fund of adverse market developments in
the manner or to the extent contemplated or that such transactions will result
in losses to the Fund which are not offset by gains with respect to
corresponding portfolio securities owned or to be purchased by that Fund.

To some extent, these risks can be minimized by careful management of these
strategies.  For example, where price movements in a futures contract are
expected to be less volatile than price movements in the related portfolio
securities owned or intended to be acquired by a Fund, it may, in order to
compensate for this difference, use an amount of futures contracts which is
greater than the amount of such portfolio securities.  Similarly, where the
price movement of a futures contract is anticipated to be more volatile, a Fund
may use an amount of such contracts which is smaller than the amount of
portfolio securities to which such contracts relate.

The risk that the hedging technique used will not actually or entirely offset an
adverse change in the value of a Fund's securities is particularly relevant to
futures contracts.  A Fund, in entering into a futures purchase contract,
potentially could lose any or all of the contract's settlement price.  In
addition, because stock index futures contracts require delivery at a future
date of an amount of cash equal to a multiple of the difference between the
value of a specified stock index on that date and the settlement price, an
algebraic relationship exists between any price movement in the underlying index
and the potential cost of settlement to a Fund.  A small increase or decrease in
the value of the underlying index can, therefore, result in a much greater
increase or decrease in the cost to the Fund.

Although the Funds intend to establish positions in these instruments only when
there appears to be an active market, there is no assurance that a liquid market
for such instruments will exist when they seek to "close out" (i.e. terminate) a
particular stock index futures contract position.  Trading in such instruments
could be interrupted, for example, because of a lack of either buyers or
sellers.  In addition, the futures exchanges may suspend trading after the price
of such instruments has risen or fallen more than the maximum amount specified
by the 

                                     
<PAGE>
 
exchange.  A Fund may be able, by adjusting investment strategy in the cash or
other contract markets, to offset to some extent any adverse effects of being
unable to liquidate a futures position. Nevertheless, in some cases, a Fund may
experience losses as a result of such inability.  Therefore it may have to
liquidate other more advantageous investments to meet its cash needs.

In addition, FCMs or brokers in certain circumstances will have access to the
Funds' assets posted as margin in connection with these transactions as
permitted under the Act.  The Funds will use only FCMs or brokers in whose
reliability and financial soundness they have full confidence and have adopted
certain other procedures and limitations to reduce the risk of loss with respect
to any assets which brokers hold or to which they may have access. Nevertheless,
in the event of a broker's insolvency or bankruptcy, it is possible that a Fund
could experience a delay or incur costs in recovering such assets or might
recover less than the full amount due.  Also the value of such assets could
decline by the time the Fund could effect such recovery.

The success of any Fund in using these techniques depends, among other things,
on BGFA's ability to predict the direction and volatility of price movements in
the futures markets as well as the securities markets and on its ability to
select the proper type, time, and duration of futures contracts.  There can be
no assurance that these techniques will produce their intended results.  In any
event, BGFA will use stock index futures contracts and options thereon only when
it believes the overall effect is to reduce, rather than increase, the risks to
which the Fund is exposed.  These transactions also, of course, may be more,
rather than less, favorable to a Fund than originally anticipated.

INVESTMENT RESTRICTIONS

FUNDAMENTAL RESTRICTIONS

The Funds are subject to certain fundamental restrictions on their investments.
These restrictions may not be changed without the approval of the holders of a
majority of the outstanding voting shares of the Funds affected by the change.

     1.   Diversification.  No Fund will make any investment inconsistent with 
          ---------------                                                 
          the Fund's classification as a diversified company under the Act. This
          restriction does not apply to any Fund classified as a non-diversified
          company under the Act.

     2a.  Industry Concentration -- Bond Fund.  The Bond Fund will not invest
          -----------------------------------                                
          more than 25% of its total assets (taken at market value at the time
          of each investment) in the securities of issuers primarily engaged in
          the same industry (excluding the U.S. Government or any of its
          agencies or instrumentalities).

     2b.  Industry Concentration -- Money Market Fund.  The Money Market Fund
          -------------------------------------------                        
          will not invest more than 25% of its assets (taken at market value at
          the time of each investment) other than U.S. Government securities,
          obligations (other than commercial paper) issued or guaranteed by U.S.
          banks and U.S. branches of foreign banks, and repurchase agreements
          and securities loans collateralized by U.S. Government securities or
          such bank obligations, in the securities of issuers primarily engaged
          in the same industry.
    
     2c.  Industry Concentration -- Equity Index Funds.  The Large Cap, Small
          --------------------------------------------
          Cap, and International Equity Index Funds will concentrate their
          investments in an industry or industries if, and to the extent that,
          their benchmark indices concentrate in such industry or industries,
          except where the concentration of the relevant index is the result of
          a single stock.
     
     3.   Interests in Real Estate.  No Fund will purchase real estate or any
          ------------------------                                           
          interest therein, except through the purchase of corporate or certain
          government securities (including securities secured by a mortgage or a
          leasehold interest or other interest in real estate). A security
          issued by a real estate or mortgage investment trust is not treated as
          an interest in real estate.

     4.   Underwriting.  No Fund will underwrite securities of other issuers 
          ------------     
          except insofar as the Trust may be deemed an underwriter under the
          Securities Act of 

                                     
<PAGE>
 
          1933 in selling portfolio securities.

     5.   Borrowing. No Fund will borrow money, except that: (a) a Fund may
          ---------
          borrow from banks (as defined in the Act) or through reverse
          repurchase agreements in amounts up to 33 1/3% of its total assets
          (including the amount borrowed), taken at market value at the time of
          the borrowing; (b) a Fund may, to the extent permitted by applicable
          law, borrow up to an additional 5% of its total assets (including the
          amount borrowed), taken at market value at the time of the borrowing,
          for temporary purposes; and (c) a Fund may obtain such short-term
          credits as may be necessary for clearance of purchases and sales of
          portfolio securities.

     6.   Lending.  No Fund will lend any security or make any other loan, 
          -------  
          except through: (a) the purchase of debt obligations in accordance
          with the Fund's investment objective or objectives and policies; (b)
          repurchase agreements with banks, brokers, dealers, and other
          financial institutions; and (c) loans of securities as permitted by
          applicable law.

     7.   Commodities.  No Fund will purchase or sell commodities or commodity
          -----------                                                         
          contracts, except that a Fund may invest in currency and financial
          instruments and contracts that are commodities or commodities
          contracts.

     8.   Senior Securities.  No Fund will issue senior securities to the extent
          -----------------                                                     
          such issuance would violate applicable law.

     9.   Investments -- Stock and Bond Balanced Fund.  The Stock and Bond 
          -------------------------------------------
          Balanced Fund will not invest in securities other than securities of
          other registered investment companies or registered unit investment
          trusts that are part of the State Farm group of investment companies
          (as defined in the Act), U.S. Government securities, or short-term
          paper.

For the purposes of the restrictions relating to industry concentration, state
and municipal governments and their agencies, authorities, and instrumentalities
are not deemed to be industries; utilities will be divided according to their
services (for example, gas, gas transmission, electric and telephone each will
be considered a separate industry); personal credit finance companies and
business credit finance companies are deemed to be separate industries; and
wholly-owned finance companies are considered to be in the industry of their
parents if their activities are primarily related to financing the activities of
their parents.

NON-FUNDAMENTAL RESTRICTIONS
    
The Trust has also adopted the following additional investment restrictions
applicable (except as noted) to all Funds.  These are not fundamental and may be
changed by the Board of      

                                     
<PAGE>
 
    
Trustees without shareholder approval. Under these restrictions, no Fund 
may:     

     1.   Financial Futures Contracts.  No Fund may enter into a financial 
          --------------------------- 
          futures contract (by exercise of any option or otherwise) or acquire
          any options thereon, if, immediately thereafter, the total of the
          initial margin deposits required with respect to all open futures
          positions, at the time such positions were established, plus the sum
          of the premiums paid for all unexpired options on futures contracts
          would exceed 5% of the value of its total assets.

     2.   Margin Purchases.  No Fund may purchase any securities on margin 
          ----------------    
          except in connection with investments of certain Funds in futures
          contracts or options on futures contracts.
    
     3.   Pledging Assets.  No Fund may mortgage, pledge, hypothecate or in any
          ---------------                                                      
          manner transfer, as security for indebtedness, any securities owned or
          held by such Fund except: (a) as may be necessary in connection with
          borrowings mentioned in fundamental restriction number 5 above, and
          then such mortgaging, pledging or hypothecating may not exceed 10% of
          the Fund's total assets, taken at market value at the time thereof, or
          (b) in connection with investments of certain Funds in futures
          contracts or options on futures contracts.       
    
     4a.  Illiquid Securities and Repurchase Agreements. No Fund may purchase 
          ---------------------------------------------
          securities or enter into a repurchase agreement if, as a result, more
          than 15% of its net assets would be invested in any combination of:
          (i) repurchase agreements not entitling the holder to payment of
          principal and interest within seven days, and (ii) securities that are
          illiquid by virtue of legal or contractual restrictions on resale or
          the absence of a readily available market.      

     4b.  Illiquid Securities and Repurchase Agreements -- Money Market Fund.  
          ------------------------------------------------------------------ 
          In addition to the non-fundamental restriction in 4a above, the Money
          Market Fund will not invest in illiquid securities, including certain
          repurchase agreements or time deposits maturing in more than seven
          days, if, as a result thereof, more than 10% of the value of its total
          assets would be invested in assets that are either illiquid or are not
          readily marketable.

     5.   Investments in Other Investment Companies.  No Fund may invest more 
          -----------------------------------------    
          than 5% of its total assets in the securities of any single investment
          company or more 

                                     
<PAGE>
 
     than 10% of its total assets in the securities of other investment
     companies in the aggregate, or hold more than 3% of the total outstanding
     voting stock of any single investment company. These restrictions do not
     apply to the Stock and Bond Balanced Fund.

State insurance laws and regulations may impose additional limitations on
borrowing, lending, and the use of futures contracts, options on futures
contracts and other derivative instruments. In addition, such laws and
regulations may require a Fund's investments in foreign securities to meet
additional diversification and other requirements.

INDUSTRY CONCENTRATIONS

The Stock and Bond Balanced Fund, because of its investment objective and
policies, will concentrate more than 25% of its total assets in the mutual fund
industry.

As a result of the equity index Funds' policy on concentration, each equity
index Fund will maintain at least 25% of the value of its total assets in
securities of issuers in each industry for which its benchmark index has a
concentration of more than 25% (except where the concentration of the index is
the result of a single stock).  No equity index Fund will concentrate its
investments otherwise. If the benchmark index for an equity index Fund has a
concentration of more than 25% because of a single stock (i.e., if one stock in
the benchmark index accounts for more than 25% of the index and it is the only
stock in the index in its industry), the equity index Fund will invest less than
25% of its total assets in such stock and will reallocate the excess to stocks
in other industries.  Changes in an equity index Fund's concentration (if any)
and non-concentration would be made "passively" -- that is, any such changes
would be made solely as a result of changes in the concentrations of the
benchmark index's constituents.  Since the concentration of each equity index
Fund is based on that of its benchmark index, changes in the market values of

INVESTMENT ADVISORY AGREEMENTS

Between The Trust And SFIM
    
The duties and responsibilities of SFIM are specified in the Investment Advisory
and Management Services Agreement between the Trust and SFIM and the separate
Service Agreement among the Trust, SFIM and State Farm Mutual Automobile
Insurance Company ("SFMAIC") (collectively, the "Management Agreements"). The
Management Agreements were approved for each Fund by the Board of Trustees of
the Trust (including a majority of Trustees who are not parties to the Agreement
or interested persons, as defined by the Act, of any such party) at a meeting
held for that purpose on September 12, 1997 and the shareholders of each Fund at
a meeting held on _________. The Management Agreements are not assignable and
each may be terminated without penalty upon 60 days written notice at the option
of the Trust, SFIM or SFMAIC, as appropriate, or by a vote of shareholders. Each
Management Agreement provides that it shall continue in effect for two years and
can thereafter be continued for each Fund from year to year so long as such
continuance is specifically approved annually (a) by the Board of Trustees of
the Trust or by a majority of the outstanding voting shares of the Fund and (b)
by a majority vote of the Trustees who are not parties to the Agreement, or
interested persons of any such party, cast in person at a meeting held for that
purpose.    

                                     
<PAGE>
 
    
SFIM (under the supervision of the Board of Trustees) continuously furnishes an
investment program for the Funds other than the Large Cap, Small Cap, and
International Equity Index Funds, is responsible for the actual managing of the
investments of such Funds and has responsibility for making decisions governing
whether to buy, sell or hold any particular security. In carrying out its
obligations to manage the investment and reinvestment of the assets of these
Funds, SFIM performs research and obtains and evaluates pertinent economic,
statistical and financial data relevant to the investment policies of these
Funds.     

As described below, SFIM has engaged Barclays Global Fund Advisors ("BGFA") as
the investment sub-adviser to provide day-to-day portfolio management for the
Large Cap, Small Cap, and International Equity Index Funds.
    
SFIM is responsible for payment of all expenses it may incur in performing the
services described. These expenses include costs incurred in providing
investment advisory services, compensating and furnishing office space for
officers and employees of SFIM connected with investment and economic research,
trading and investment management of the Trust and the payment of any fees to
interested Trustees of the Trust. SFIM provides all executive, administrative,
clerical and other personnel necessary to operate the Trust and pays the
salaries and other employment related costs of employing those persons. SFIM
furnishes the Trust with office space, facilities and equipment and pays the 
day-to-day expenses related to the operation and maintenance of such office
space facilities and equipment. All other expenses incurred in the organization
of the Trust or of new Funds of the Trust, including legal and accounting
expenses and costs of registering securities of the Trust under federal and
state securities laws, are also paid by SFIM.     

Pursuant to the Service Agreement, SFMAIC provides SFIM with certain personnel,
services and facilities to enable SFIM to perform its obligations to the Trust.
SFIM reimburses SFMAIC for such costs, direct and indirect, as are fairly
attributable to the services performed and the facilities provided by SFMAIC
under the separate service agreement. Accordingly, the Trust makes no payment to
SFMAIC under the Service Agreement.
    
The Trust is responsible for payment of all expenses it may incur in its
operation and all of its general administrative expenses except those expressly
assumed by SFIM as described in the preceding paragraphs. These include (by way
of description and not of limitation), any share redemption expenses, expenses
of portfolio transactions, shareholder servicing costs, pricing costs (including
the daily calculation of net asset value), interest on borrowings by the Trust,
charges of the custodian and transfer agent, if any, cost of auditing services,
non-interested Trustees' fees, legal expenses, all taxes and fees, investment
advisory fees, certain insurance premiums, cost of maintenance of corporate
existence, investor services (including allocable personnel and telephone
expenses), costs of printing and mailing updated Trust prospectuses to
shareholders and contractholders, costs of preparing, printing, and mailing
proxy statements and shareholder reports to shareholders and contractholders,
the cost of paying dividends and    

                                     
<PAGE>
 
    
capital gains distribution, capital stock certificates, costs of Trustee and
shareholder meetings, dues to trade organizations, and any extraordinary
expenses, including litigation costs in legal actions involving the Trust, or
costs related to indemnification of Trustees, officers and employees of the
Trust.     
    
The Board of Trustees of the Trust determines the manner in which expenses are
allocated among the Funds of the Trust.     

The Agreement also provides that SFIM shall not be liable to the Trust or to any
shareholder or contract owner for any error of judgment or mistake of law or for
any loss suffered by the Trust or by any shareholder in connection with matters
to which the such Agreements relate, except for a breach of fiduciary duty or a
loss resulting from willful misfeasance, bad faith, gross negligence, or
reckless disregard on the part of SFIM in the performance of its duties
thereunder.

Between SFIM And BGFA

Pursuant to the separate sub-advisory agreement described below (the "Sub-
advisory Agreement"), SFIM has engaged BGFA as the investment sub-adviser to
provide day-to-day portfolio management for the Large Cap, Small Cap, and
International Equity Index Funds.
    
The Sub-Advisory Agreement was approved for each Fund by the Board of Trustees
of the Trust (including a majority of Trustees who are not parties to such
Agreements or interested persons, as defined by the Act, of any such party) at a
meeting held for that purpose on September 12, 1997 and the shareholders of each
Fund at a meeting held on _________. The Sub-advisory Agreement is not
assignable and may be terminated without penalty upon 60 days written notice at
the option of SFIM or BGFA, or by the Board of Trustees of the Trust or by a
vote of a majority of the outstanding shares of the class of stock representing
an interest in the appropriate Fund. The Sub-advisory Agreement provides that it
shall continue in effect for two years and can thereafter be continued for each
Fund from year to year so long as such continuance is specifically approved
annually (a) by the Board of Trustees of the Trust or by a majority of the
outstanding shares of the Fund and (b) by a majority vote of the Trustees who
are not parties to the Agreement, or interested persons of any such party, cast
in person at a meeting held for that purpose.     

BGFA manages the investments of the Large Cap, Small Cap, and International
Equity Index Funds, respectively, determining which securities or other
investments to buy and sell for each, selecting the brokers and dealers to
effect the transactions, and negotiating commissions. In placing orders for
securities transactions, BGFA follows SFIM's policy of seeking to obtain the
most favorable price and efficient execution available.

                                     
<PAGE>
 
TRACKING ERROR

SFIM and BGFA use the "expected tracking error" of an equity index Fund as a way
to measure the Funds' performance relative to the performance of its benchmark
index. An expected tracking error of 5% means that there is a 68% probability
that the net asset value of the equity index Fund will be between 95% and 105%
of the subject index level after one year, without rebalancing the portfolio
composition. A tracking error of 0% would indicate perfect tracking, which would
be achieved when the net asset value of the equity index Fund increases or
decreases in exact proportion to changes in its benchmark index. Factors such as
expenses of the Fund, taxes, the need to comply with the diversification and
other requirements of the Code and other requirements may adversely impact the
tracking of the performance of an equity index Fund to that of its benchmark
index. In the event that tracking error exceeds 5%, the Board of Trustees of the
Trust will consider what action might be appropriate to reduce the tracking
error.

SECURITIES ACTIVITIES OF THE INVESTMENT ADVISERS
    
Securities held by the Trust may also be held by separate accounts or mutual
funds for which SFIM or BGFA acts as an adviser, some of which may be affiliated
with SFIM or BGFA. Because of different investment objectives or other factors,
a particular security may be bought by SFIM or BGFA for one or more of its
clients, when one or more other clients are selling the same security. If
purchases or sales of securities for a Fund or other client of SFIM or BGFA
arise for consideration at or about the same time, transactions in such
securities will be allocated as to amount and price, insofar as feasible, for
the Fund and other clients in a manner deemed equitable to all. To the extent
that transactions on behalf of more than one client of SFIM or BGFA during the
same period may increase the demand for securities being purchased or the supply
of securities being sold, there may be an adverse effect on price. It is the
opinion of the Trustees of the Trust, however, that the benefits available to
the Trust outweigh any possible disadvantages that may arise from such
concurrent transactions.       
    
On occasions when SFIM or BGFA (under the supervision of the Board of Trustees)
deems the purchase or sale of a security to be in the best interests of the
Trust as well as other accounts or companies, it may, to the extent permitted by
applicable laws and regulations, but will not be obligated to, aggregate the
securities to be sold or purchased for the Trust with those to be sold or
purchased for other accounts or companies in order to obtain favorable execution
and low brokerage commissions. In that event, allocation of the securities
purchased or sold, as well as the expenses incurred in the transaction, will be
made by SFIM or BGFA in the manner it considers to be most equitable and
consistent with its fiduciary obligations to the Trust and to such other
accounts or companies. In some cases this procedure may adversely affect the
size of the position obtainable for a Fund.     

                                     
<PAGE>
 
In performing their functions, neither SFIM nor BGFA will execute private sales
of securities among the Funds or between a Fund and any other investment account
it manages.

                     PORTFOLIO TRANSACTIONS AND BROKERAGE

As described above, either SFIM or BGFA determines which securities to buy and
sell for the Funds, selects brokers and dealers to effect the transactions, and
negotiates commissions. Transactions in equity securities will usually be
executed through brokers who will receive a commission paid by the Fund. Fixed
income securities are generally traded with dealers acting as principals for
their own accounts without a stated commission. The dealer's margin is reflected
in the price of the security. Money market obligations may be traded directly
with the issuer. Underwritten offerings of stock may be purchased at a fixed
price including an amount of compensation to the underwriter.
    
In placing orders for securities transactions, SFIM's policy (followed by BGFA)
is to attempt to obtain the most favorable price and efficient execution
available. These entities, subject to the review of the Trust's Board of
Trustees, may pay higher than the lowest possible commission in order to obtain
better than average execution of transactions and/or valuable investment
research information described below, if, in their opinion, improved execution
and investment research information will benefit the performance of each of the
Funds.     
    
When selecting broker-dealers to execute portfolio transactions, SFIM considers
factors including the rate of commission or size of the broker-dealer's
"spread", the size and difficulty of the order, the nature of the market for the
security, the willingness of the broker-dealer to position, the reliability,
financial condition and general execution and operational capabilities of the
broker-dealer, and the research, statistical and economic data furnished by the
broker-dealer to SFIM. In some cases, SFIM may use such information to advise
other investment accounts that it advises. Brokers or dealers which supply
research may be selected for execution of transactions for such other accounts,
while the data may be used by SFIM in providing investment advisory services to
the Trust. In addition, SFIM may select broker-dealers to execute portfolio
transactions who are affiliated with the Trust or SFIM. However, all such
directed brokerage will be subject to SFIM's policy to attempt to obtain the
most favorable price and efficient execution possible.       

PORTFOLIO TURNOVER
    
There are no fixed limitations regarding the portfolio turnover rate for either
the Bond Fund or Money Market Fund, and securities initially satisfying the
     
<PAGE>
 
objectives and policies of one of these Funds may be disposed of when they are
no longer deemed suitable. Consistent with each equity index Fund's investment
objective, the Large Cap, Small Cap, and International Equity Index Funds will
attempt to minimize portfolio turnover. The Stock and Bond Balanced Fund's
portfolio turnover is expected to be low. The Stock and Bond Balanced Fund will
purchase or sell securities to: (i) accommodate purchases and sales of its
shares; (ii) change the percentages of its assets invested in each of the
underlying Funds in response to market conditions; and (iii) maintain or modify
the allocation of its assets among the underlying Funds within the percentage
limits described in the Prospectus.

Since short term instruments are excluded from the calculation of a portfolio
turnover rate, no meaningful portfolio turnover rate can be estimated or
calculated for the Money Market Fund. Turnover rates may vary greatly from year
to year as well as within a particular year and may also be affected by cash
requirements for redemptions of a Fund's shares and by requirements, the
satisfaction of which enable the Trust to receive certain favorable tax
treatment.

                       DETERMINATION OF NET ASSET VALUE
    
The net asset value of each Fund is determined as of the time of the close of
regular session trading on the New York Stock Exchange, (currently at 4:00 PM,
New York City time) on each day when the New York Stock Exchange is open except
as noted below. The New York Stock Exchange is scheduled to be open Monday
through Friday throughout the year, except for certain federal and other
holidays. The net asset value of each Fund will not be calculated on the Friday
following Thanksgiving or on December 26, 1997. The net asset value per share is
computed by dividing the difference between the value of the Fund's assets and
liabilities by the number of shares outstanding. Interest earned on portfolio
securities and expenses, including fees payable to SFIM, are accrued daily.     

Equity securities (including common stocks, preferred stocks, convertible
securities and warrants) and call options written on all portfolio securities,
listed or traded on a national exchange are valued at their last sale price on
that exchange prior to the time when assets are valued. In the absence of any
exchange sales on that day and for unlisted equity securities, such securities
are valued at the last sale price on the Nasdaq (National Association of
Securities Dealers Automated Quotations) National Market. In the absence of any
National Market sales on that day, equity securities are valued at the last
reported bid price.
    
Debt securities traded on a national exchange are valued at their last sale
price on that exchange prior to the time when assets are valued, or, lacking any
sales, at the last reported bid price. Debt securities other than money market
instruments traded in the over-the-counter market are valued at the last
reported bid price or at yield equivalent as obtained from one or more dealers
that make markets in the securities.      

<PAGE>
 
     
If the market quotations described above are not available, debt securities,
other than short-term debt securities, may be valued at fair value as determined
by one or more independent pricing services (each, a "Service"). The Service may
use available market quotations and employ electronic data processing techniques
and/or a matrix system to determine valuations. Each Service's procedures are
reviewed by the officers of the Trust under the general supervision of the Board
of Trustees.     
    
Debt instruments held with a remaining maturity of 60 days or less (other than
U.S. Treasury bills) are generally valued on an amortized cost basis. Under the
amortized cost basis method of valuation, the security is initially valued at
its purchase price (or in the case of securities purchased with more than 60
days remaining to maturity, the market value on the 61st day prior to maturity),
and thereafter by amortizing any premium or discount uniformly to maturity. If
for any reason the Trustees believe the amortized cost method of valuation
does not fairly reflect the fair value of any security, fair value will be
determined in good faith by or under the direction of the Board of Trustees of
the Trust as in the case of securities having a maturity of more than 60
days.    

Securities that are primarily traded on foreign securities exchanges are
generally valued at the last sale price on the exchange where they are primarily
traded. All foreign securities traded on the over-the-counter market are valued
at the last sale quote, if market quotes are available, or the last reported bid
price if there is no active trading in a particular security on a given day.
Quotations of foreign securities in foreign currencies are converted, at current
exchange rates, to their U. S. dollar equivalents in order to determine their
current value. Forward currency contracts are valued at the current cost of
offsetting the contract. Because of the need to value foreign securities (other
than American Depositary Receipts) as of the close of trading on various
exchanges and over-the-counter markets throughout the world, the calculation of
the net asset value of Funds investing in foreign securities may not take place
contemporaneously with the valuation of such foreign securities in such Funds.
In addition, foreign securities held by the Large Cap and International Equity
Index Funds may be traded actively in securities markets which are open for
trading on days when those Funds do not calculate their net asset value.
Accordingly, there may be occasions when the Large Cap or International Equity
Index Fund does not calculate its net asset value but when the value of such
Fund's portfolio securities is affected by such trading activity.
    
Securities for which market quotations are not readily available are valued at
fair value as determined in good faith by or under the direction of the Board of
Trustees of the Trust, including valuations provided by a Service retained for
this purpose.     

Exchange listed put options written and options purchased are valued on the
primary exchange on which they are traded. Over-the-counter options written or
purchased by a Fund are valued 

<PAGE>
 
based upon prices provided by market-makers in such securities. Exchange-traded
financial futures contracts are valued at their settlement price established
each day by the board of trade or exchange on which they are traded.

All of the assets of the Money Market Fund are valued on the basis of amortized
cost in an effort to maintain a constant net asset value of $1.00 per share. The
Board of Trustees of the Trust (the "Board") has determined this to be in the
best interests of the Money Market Fund and its shareholders. Under the
amortized cost method of valuation, securities are valued at cost on the date of
their acquisition, and thereafter as adjusted for amortization of premium or
accretion of discount, regardless of the impact of fluctuating interest rates on
the market value of the security. While this method provides certainty in
valuation, it may result in periods in which value as determined by amortized
cost is higher or lower than the price the Fund would receive if it sold the
security. During such periods, the quoted yield to investors may differ somewhat
from that obtained by a similar fund or portfolio which uses available market
quotations to value all of its portfolio securities.

The Board has established procedures reasonably designed, taking into account
current market conditions and the Money Market Fund's investment objectives, to
stabilize the net asset value per share for purposes of sales and redemptions at
$1.00. These procedures include review by the Board, at such intervals as it
deems appropriate, to determine the extent, if any, to which the net asset value
per share calculated by using available market quotations deviates from $1.00
per share. In the event such deviation should exceed one half of one percent,
the Board will promptly consider initiating corrective action. If the Board
believes that the extent of any deviation from a $1.00 amortized cost price per
share may result in material dilution or other unfair results to new or existing
shareholders, it will take such steps as it considers appropriate to eliminate
or reduce these consequences to the extent reasonably practicable. Such steps
may include: selling portfolio securities prior to maturity; shortening the
average maturity of the portfolio; withholding or reducing dividends; or
utilizing a net asset value per share determined from available market
quotations. Even if these steps were taken, the Money Market Fund's net asset
value might still decline.

                            PERFORMANCE INFORMATION

The Trust may from time to time quote or otherwise use average annual total
return information for the Funds in advertisements, shareholder reports or sales
literature. Average annual total return values are computed pursuant to
equations specified by the Commission.

Average annual total return for a specified period is derived by calculating the
actual dollar amount of the investment return on a $1,000 investment in a Fund
made at the beginning of the period, and then calculating the annual compounded
rate of return which would produce that amount, assuming a redemption at the end
of the period. This calculation assumes a 

<PAGE>
 
complete redemption of the investment. It also assumes that all dividends and
distributions are reinvested at net asset value on the reinvestment dates during
the period.

The Trust also may from time to time quote or otherwise use year-by-year total
return, cumulative total return and yield information for the Funds in
advertisements, shareholder reports or sales literature. Year-by-year total
return and cumulative total return for a specified period are each derived by
calculating the percentage rate required to make a $1,000 investment in a Fund
(assuming that all distributions are reinvested) at the beginning of such period
equal to the actual total value of such investment at the end of such period.

Yield is computed by dividing net investment income earned during a recent 30
day period by the product of the average daily number of shares outstanding and
entitled to receive dividends during the period and the price per share on the
last day of the relevant period. The results are compounded on a bond equivalent
(semi-annual) basis and then annualized. Net investment income is equal to the
dividends and interest earned during the period, reduced by accrued expenses for
the period. The calculation of net investment income for these purposes may
differ from the net investment income determined for accounting purposes.
    
Any performance data quoted for a Fund will represent historical performance and
the investment return and principal value of an investment will fluctuate so
that shares, when redeemed, may be worth more or less than original cost.     

From time to time the Trust may publish an indication of the Funds' past
performance as measured by independent sources such as (but not limited to)
Lipper Analytical Services, Incorporated, Weisenberger Investment Companies
Service, Donoghue's Money Fund Report, Barron's, Business Week, Changing Times,
Financial World, Forbes, Fortune, Money, Personal Investor, Sylvia Porter's
Personal Finance and The Wall Street Journal. The Trust may also advertise
information which has been provided to the NASD for publication in regional and
local newspapers. In addition, the Trust may from time to time advertise its
performance relative to certain indices and benchmark investments, including (a)
the Lipper Analytical Services, Inc. Mutual Fund Performance Analysis, Fixed-
Income Analysis and Mutual Fund Indices (which measure total return and average
current yield for the mutual fund industry and rank mutual fund performance);
(b) the CDA Mutual Fund Report published by CDA Investment Technologies, Inc.
(which analyzes price, risk and various measures of return for the mutual fund
industry); (c) the Consumer Price Index published by the U.S. Bureau of Labor
Statistics (which measures changes in the price of goods and services); (d)

or its component indices (the Aggregate Bond Index measures the performance of
Treasury, US. Government agencies, mortgage and Yankee bonds); (m) the S&P Bond
indices (which measure yield and price of corporate, municipal and U.S.
Government bonds); (n) the J.P. Morgan Global Government Bond Index; (o)
Donoghue's Money Market Fund Report (which provides industry averages of 7-day
annualized and compounded yields of taxable, tax-free and U.S. Government money
market funds); (p) other taxable investments including certificates of deposit,
money market deposit accounts, checking accounts, savings accounts, money market
mutual funds and repurchase agreements; (q) historical investment data supplied
by the research departments of Goldman Sachs, Lehman Brothers, First Boston
Corporation, Morgan Stanley (including EAFE "Free"), Salomon Brothers, Merrill
Lynch, Donaldson Lufkin and Jenrette or other providers of such data; (r) the
FT-Actuaries Europe and Pacific Index; (s) mutual fund performance indices
published by Variable Annuity Research & Data Service; and (t) mutual fund
performance indices published by Morningstar, Inc. The composition of the
investments in such indices and the characteristics of such benchmark
investments are not identical to, and in some cases are very different from,
those of a Fund's portfolio. These indices and averages are generally unmanaged
and the items included in the calculations of such indices and averages may be
different from those of the equations used by the Trust to calculate a Fund's
performance figures.    

The Trust may from time to time summarize the substance of discussions contained
in shareholder reports in advertisements and publish the Advisers' views as to
markets, the rationale for a Fund's investments and discussions of the Fund's
current asset allocation.

From time to time, advertisements or information may include a discussion of
certain attributes or benefits to be derived by an investment in a particular
Fund. Such advertisements or information may include symbols, headlines or other
material which highlight or summarize the information discussed in more detail
in the communication.

Such performance data will be based on historical results and will not be
intended to indicate future performance. The total return or yield of a Fund
will vary based on market conditions, portfolio expenses, portfolio investments
and other factors. The value of a Fund's shares will fluctuate and your shares
may be worth more or less than their original cost upon redemption.

                          DIVIDENDS AND DISTRIBUTIONS

It is the Trust's intention to distribute substantially all the net investment
income, if any, of a Fund. Dividends from net investment income of a Fund will
be paid at least semi-annually and are expected to be reinvested in additional
full and fractional shares of that Fund. Shares 

<PAGE>
 
will begin accruing dividends on the day following the date on which the shares
are issued, the date of issuance customarily being the "settlement" date.

                             REDEMPTION OF SHARES

Shares are redeemed at the net asset value per share next determined after the
receipt of proper notice of redemption. Payment for redeemed shares will
generally occur within seven days of receipt of a proper notice of redemption.
The Trust reserves the right to redeem shares in kind.

The right to redeem shares or to receive payment with respect to any redemption
may be suspended for any period during which trading on the New York Stock
Exchange is restricted as determined by the Commission or when such Exchange is
closed (other than customary weekend and holiday closings) for any period during
which an emergency exists, as defined by the Commission, which makes disposal of
a Fund's securities or determination of the net asset value of a Fund not
reasonably practicable, and for any other periods as the Commission may by order
permit for the protection of shareholders of the Fund.

CODE OF ETHICS
    
SFIM intends that: all of its activities function exclusively for the benefit of
the owners or beneficiaries of the assets it manages; assets under management or
knowledge as to current or prospective transactions in managed assets are not
utilized for personal advantage or for the advantage of anyone other than the
owners or beneficiaries of those assets; persons associated with SFIM and the
Trust avoid situations involving actual or potential conflicts of interest with
the owners or beneficiaries of managed assets; and situations appearing to
involve actual or potential conflicts of interest or impairment of objectivity
are avoided whenever doing so does not run counter to the interests of the
owners or beneficiaries of the managed assets. The Board of Trustees of the
Trust has adopted a Code of Ethics which imposes certain prohibitions,
restrictions, preclearance requirements and reporting rules on the personal
securities transactions of subscribers to the Code, who include the Trust's
officers and Trustees and the employees of SFIM. Barclays has adopted a similar
Code of Ethics relating to its employees, and the Board of Trustees of the Trust
has adopted Barclays' Code of Ethics insofar as it relates to Barclays'
employees' activities in connection with the Trust. The Board of Trustees
believes that the provisions of its Code of Ethics and Barclays' Code of Ethics
are reasonably designed to prevent subscribers from engaging in conduct that
violates these principles.    

INDEPENDENT AUDITORS

Ernst & Young, LLP acts as independent auditors for the Trust. Its offices are
at 233 South Wacker Drive, Chicago, Illinois 60606. Ernst & Young, LLP performs
an audit of the financial statements of the Trust annually.

LEGAL COUNSEL
    
Sutherland, Asbill & Brennan LLP, 1275 Pennsylvania Avenue, NW, Washington, DC
20004-2404, is counsel for the Trust.     

SHARES
    
The Trust was organized as a business trust pursuant to the laws of the State of
Delaware on February 21, 1997. The Trust is authorized to issue an unlimited
number of shares of beneficial interest in the Trust, all without par value.
Shares are divided into and may be issued in a designated series representing
beneficial interests in one of the Trust's Funds. There are currently six series
of shares.      

<PAGE>
 
Each share of a series issued and outstanding is entitled to participate equally
in dividends and distributions declared by such series and, upon liquidation or
dissolution, in net assets allocated to such series remaining after satisfaction
of outstanding liabilities. The shares of each series, when issued, will be
fully paid and non-assessable and have no preemptive or conversion rights.
    
State Farm Life Insurance Company ("State Farm") provided the initial capital
for the Trust by purchasing $15,000,000, $30,000,000, $54,000,000, $10,000,000,
and $10,000,000 of shares in the Large Cap Equity Index, Small Cap Equity
Index, International Equity Index, Bond, and Money Market Funds, respectively.
Such shares were acquired for investment and can only be disposed of by
redemption.    

VOTING RIGHTS
    
Each share (including fractional shares) is entitled to one vote for each dollar
of net asset value represented by that share on all matters to which the holder
of that share is entitled to vote. Only shares representing interests in a
particular Fund will be entitled to vote on matters affecting only that Fund.
The shares do not have cumulative voting rights. Accordingly, owners of variable
annuity or variable life insurance contracts having shares representing more
than 50% of the assets of the Trust voting for the election of Trustees could
elect all of the Trustees of the Trust if they choose to do so, and in such
event, contract owners or plan participants having voting interests in the
remaining shares would not be able to elect any Trustees.     

Matters requiring separate shareholder voting by Fund shall have been
effectively acted upon with respect to any Fund if a majority of the outstanding
voting interests of that Fund vote for approval of the matter, notwithstanding
that: (1) the matter has not been approved by a majority of the outstanding
voting interests of any other Fund; or (2) the matter has not been approved by a
majority of the outstanding voting interests of the Trust.

APPENDIX A -- DESCRIPTION OF MONEY MARKET SECURITIES

The following information includes a description of certain money market
instruments in which a Fund may invest to the extent consistent with its
investment objective.

Bank Money Instruments. These include instruments, such as certificates of
deposit and bankers' acceptances. Certificates of deposit are generally 
short-term, interest-bearing negotiable certificates issued by commercial banks
or savings and loan associations against funds deposited in the issuing
institution. A bankers' acceptance is a time draft drawn on a commercial bank by
a borrower usually in connection with an international commercial transaction
(to finance the import, export, transfer or storage of goods). The borrower is
liable for payment as well as the bank, which unconditionally guarantees to pay
the draft at its face amount on the maturity date. Most acceptances have
maturities of six months or less and are traded in secondary markets prior to
maturity.

A Fund may not invest in any security issued by a commercial bank or a savings
and loan association unless the bank or association is organized and operating
in the United States, has total assets of at least one billion dollars and is a
member of the Federal Deposit Insurance Corporation, in the case of banks, or
the Federal Savings and Loan Insurance Corporation, in the case of savings and
loan associations provided that this limitation shall not prohibit investments
in foreign branches of banks which meet the foregoing requirements.

Government Agency Securities. These include debt securities issued by 
government-sponsored enterprises, federal agencies or instrumentalities and
international institutions. Such securities are not direct obligations of the
U.S. Treasury but involve government sponsorship or guarantees. Thus the Trust
may not be able to assert a claim against the United States itself in the event
the agency or instrumentality does not meet its commitment.

U.S. Government Securities. These include marketable securities issued by the
U.S. Treasury, which consist of bills, notes and bonds. Such securities are
direct obligations of the U.S. government and differ mainly in the length of
their maturity. Treasury bills, the most frequently issued marketable government
security, have a maturity of up to one year and are issued on a discount basis.

Short-Term Corporate Debt Instruments. These include commercial paper (including
variable amount master demand notes), which refers to short-term unsecured
promissory notes issued by corporations to finance short-term credit needs.
Commercial paper is usually sold on a discount basis and has a maturity at the
time of issuance not exceeding nine months. Variable amount master demand notes
are demand obligations that permit the investment of fluctuating amounts at
varying market rates of interest pursuant to arrangements between the issuer and
a commercial bank acting as agent for the payees of such notes, whereby both
parties have the 

<PAGE>
 
right to vary the amount of the outstanding indebtedness on the notes.

Because variable amount master notes are direct lending arrangements between the
lender and borrower, it is not generally contemplated that such instruments will
be traded and there is no secondary market for the notes. Typically, agreements
relating to such notes provide that the lender may not sell or otherwise
transfer the note without the borrower's consent. Such notes provide that the
interest rate on the amount outstanding is adjusted periodically, typically on a
daily basis in accordance with a stated short-term interest rate benchmark.
Since the interest rate of a variable amount master note is adjusted no less
often than every 60 days and since repayment of the note may be demanded at any
time, the Trust values such a note in accordance with the amortized cost basis
at the outstanding principal amount of the note. See "Determination of Net Asset
Value" on page 19.

Also included are nonconvertible corporate debt securities (e.g., bonds and
debentures) with no more than one year remaining to maturity at the date of
settlement. Corporate debt securities with a remaining maturity of less than one
year tend to become extremely liquid and are traded as money market securities.
Such issues with less than one year remaining to maturity tend to have greater
liquidity and considerably less market value fluctuations than longer term
issues.

Commercial paper investments at the time of purchase will be rated at least "A"
by Standard and Poor's or "Prime" by Moody's, or, if not rated, issued by
companies having an outstanding debt issue rated at least "A" by Standard and
Poor's or by Moody's. See "Corporate Bond Ratings" in Appendix B.

Repurchase Agreements. A repurchase agreement is an instrument under which the
purchaser (i.e., a Fund) acquires ownership of the obligation (debt security)
and the seller agrees, at the time of the sale, to repurchase the obligation at
a mutually agreed upon time and price, thereby determining the yield during the
purchaser's holding period. This results in a fixed rate of return insulated
from market fluctuations during such period. The underlying securities will
consist only of U.S. government or government agency securities, certificates of
deposit, commercial paper or bankers' acceptances.

Repurchase agreements usually are for short periods, such as under one week.
Repurchase agreements are considered to be loans under the Act, with the
security subject to repurchase, in effect, serving as "collateral" for the loan.
The Trust will require the seller to provide additional collateral if the market
value of the securities falls below the repurchase price at any time during the
term of the repurchase agreement. In the event of a default by the seller
because of bankruptcy or otherwise, the Trust may suffer time delays and incur
costs or losses in connection with the disposition of the collateral. Repurchase
agreements will be entered into with primary dealers for periods not to exceed
30 days and only with respect to 

<PAGE>
 
underlying money market securities in which the Fund may otherwise invest.
Because a repurchase agreement maturing in more than seven days is deemed an
illiquid investment, investments in such repurchase agreements and other
illiquid assets cannot exceed 10% of the Fund's net assets.

APPENDIX B -- RATINGS

DESCRIPTION OF CORPORATE BOND RATINGS

Moody's Investors Services, Inc.

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 risks appear somewhat larger 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.

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

Ba - Bonds which are rated Ba are judged to have speculative elements; their
future cannot be considered as well assured. Often the protection of interest
and principal payments may be very moderate and thereby not well safeguarded
during both good and bad times over the future. Uncertainty of position
characterizes bonds in this class.

B - Bonds which are rated B generally lack characteristics of the desirable
investment. Assurance of interest and principal payments or of maintenance of
other terms of the contract over any long period of time may be small.

Caa - Bonds which are rated Caa are of poor standing. Such issues may be in
default or there may be present elements of danger with respect to principal or
interest.

<PAGE>
 
Ca - Bonds which are rated Ca represent obligations which are speculative in a
high degree. Such issues are often in default or have other marked shortcomings.

C - Bonds which are rated C are the lowest rated class of bonds and issues so
rated can be regarded as having extremely poor prospects of ever attaining any
real investment standing.

Moody's applies numerical modifiers, 1, 2 and 3 in each generic rating
classification from Aa through B in its corporate bond rating system. The
modifier 1 indicates that the security ranks in the higher end of its generic
rating category; the modifier 2 indicates a midrange ranking; and the modifier 3
indicates that the issue ranks in the lower end of its generic rating category.

Standard & Poor's Corporation

AAA - This is the highest rating assigned by Standard & Poor's to a debt
obligation and indicates an extremely strong capacity to pay principal and
interest.

AA - Bonds rated AA also qualify as high-quality debt obligations. Capacity to
pay principal and interest is very strong, and in the majority of instances they
differ from AAA issues only in small degree.

A - Bonds rated A have a strong capacity to pay principal and interest, although
they are somewhat more susceptible to the adverse effects of changes in
circumstances and economic conditions.

BBB - Bonds rated BBB are regarded as having an adequate capacity to pay
principal and interest. Whereas they normally exhibit protection parameters,
adverse economic conditions or changing circumstances are more likely to lead to
a weakened capacity to pay principal and interest for bonds in this category
than for bonds in the A category.

BB-B-CCC-CC - Bonds rated BB, B, CCC and CC are regarded, on balance, as
predominantly speculative with respect to the issuer's capacity to pay interest
and repay principal in accordance with the terms of the obligation. BB indicates
the lowest degree of speculation and CC the highest degree of speculation. While
such bonds will likely have some quality and protective characteristics, these
are outweighed by large uncertainties or major risk exposures to adverse
conditions.

C - The rating C is reserved for income bonds on which no interest is being
paid.

D - Debt rated D is in default, and payment of interest and/or repayment of
principal is in arrears.

<PAGE>
 
     The ratings from "AA" to "B" may be modified by the addition of a plus or
minus sign to relative standing within the major rating categories.

DESCRIPTION OF COMMERCIAL PAPER RATINGS

Commercial paper rated A-1 by Standard & Poor's has the following
characteristics: Liquidity ratios are adequate to meet cash requirements. Long-
term senior debt is rated "A" or better, although in some cases "BBB" credits
may be allowed. The issuer has access to at least two additional channels of
borrowing. Basic earnings and cash flow have an upward trend with allowance made
for unusual circumstances. Typically, the issuer's industry is well established
and the issuer has a strong position within the industry. The reliability and
quality of management are unquestioned. Relative strength or weakness of the
above factors determine whether the issuer's commercial paper is rated A-1, A-2
or A-3.

The rating Prime-1 is the highest commercial paper rating assigned by Moody's.
Among the factors considered by Moody's in assigning ratings are the following:
(1) evaluation of the management of the issuer; (2) economic evaluation of the
issuer's industry or industries and an appraisal of speculative-type risks which
may be inherent in certain areas; (3) evaluation of the issuer's products in
relation to competition and customer acceptance; (4) liquidity; (5) amount and
quality of long-term debt; (6) trends of earnings over a period of ten years;
(7) financial strength of a parent company and the relationships which exist
with the issuer, and (8) recognition by the management of obligations which may
be present or may arise as a result of public interest questions and
preparations to meet such obligations.

Declaration of Trust dated February 21, 1997 (the Declaration of Trust).
Generally, Delaware business trust shareholders are not personally liable for
obligations of the Delaware business trust under Delaware law. The Delaware
Business Trust Act (the DBTA) provides that a shareholder of a trust shall be
entitled to the same limitation of liability extended to shareholders of private
for-profit Delaware corporations. Registrant's Declaration of Trust expressly
provides that it has been organized under the DBTA and that the Declaration of
Trust is to be governed by Delaware law. It is nevertheless possible that a
Delaware business trust, such as Registrant, might become a party to an action
in another state whose courts refuse to apply Delaware law, in which case
Registrant's shareholders could be subject to personal liability.

<PAGE>
 
     To protect Registrant's shareholders against the risk of personal
liability, the Declaration of Trust: (i) contains an express disclaimer of
shareholder liability for acts or obligations of Registrant and provides that
notice of such disclaimer may be given in each agreement, obligation and
instrument entered into or executed by Registrant or its Trustees; (ii) provides
for the indemnification out of Trust property of any shareholders held
personally liable for any obligations of Registrant or any series of Registrant;
and (iii) provides that Registrant shall, upon request, assume the defense of
any claim made against any shareholder for any act or obligation of Registrant
and satisfy any judgment thereon. Thus, the risk of a shareholder incurring
financial loss beyond his or her investment because of shareholder liability is
limited to circumstances in which all of the following factors are present: (i)
a court refuses to apply Delaware law; (ii) the liability arose under tort law
or, if not, no contractual limitation of liability was in effect; and (iii)
Registrant itself would be unable to meet its obligations. In the light of
Delaware law, the nature of Registrant's business and the nature of its assets,
the risk of personal liability to a shareholder is remote.

     The Declaration of Trust further provides that Registrant shall indemnify
each of its Trustees and officers against liabilities and expenses reasonably
incurred by them, in connection with, or arising out of, any action, suit or
proceeding, threatened against or otherwise involving such Trustee or officer,
directly or indirectly, by reason of being or having been a Trustee or officer
of Registrant. The Declaration of Trust does not authorize Registrant to
indemnify any Trustee or officer against any liability to which he or she would
otherwise be subject by reason of or for willful misfeasance, bad faith, gross
negligence or reckless disregard of such person's duties.

     Insofar as indemnification for liability arising under the Securities Act
of 1933 may be permitted to Trustees, officers and controlling persons, or
otherwise, Registrant has been advised that in the opinion of the Commission
such indemnification may be against public policy as expressed in the Act and
may be, therefore, unenforceable. In the event that a claim for indemnification
against such liabilities (other than the payment by Registrant of expenses
incurred or paid by a Trustee, officer or controlling person of Registrant in
the successful defense of any action, suit or proceeding) is asserted by such
Trustee, officer or controlling person in connection with the securities being
registered, 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.

orders, administering shareholder accounts and handling shareholder relations.
The Adviser shall provide the Trust with office space, equipment, facilities and

under this agreement.  The Adviser shall also, on behalf of the Trust, conduct

<PAGE>
 
hereunder and furnish advice and recommendations with respect to such other

     2.2  Investment Management Services.
          ------------------------------ 

          (a) The Adviser shall provide the Trust with such investment research,
advice and supervision as the latter may from time to time consider necessary
for the proper supervision of the assets of each Fund.  In this regard, the
Adviser shall:

              (i) perform research and obtain and evaluate pertinent economic,
statistical, and financial data relevant to the investment policies of each Fund
as set forth in the Registration Statement;

              (ii) consult with the Board and furnish to the Board
recommendations with respect to an overall investment strategy for each Fund for
approval, modification, or rejection by the Board;

              (iii)  seek out and implement specific investment opportunities,
consistent with any investment strategies approved by the Board;

              (iv) take such steps as are necessary to implement any overall
investment strategies approved by the Board for each Fund, including making and
carrying out day-to-day decisions to acquire or dispose of permissible
investments, management of investments and any other property of the Fund, and
providing or obtaining such services as may be necessary in managing, acquiring
or disposing of investments;

              (v) regularly report to the Board with respect to the
implementation of any approved overall investment strategy and any other
activities in connection with management of the assets of each Fund including
furnishing, within 30 days after the end of each calendar quarter, a statement
of all purchases and sales during the quarter and a schedule of investments and
other assets of each Fund as of the end of the quarter;

              (vi) maintain all required accounts, records, memoranda,
instructions or authorizations relating to the acquisition or disposition of
investments for each Fund and the Trust;

              (vii) assist in determining each business day the net asset value
of the shares of each Fund in accordance with applicable law; and

              (viii) enter into any advisory or sub-advisory contract with
another affiliated or unaffiliated entity pursuant to which such entity will
carry out some or all of the Adviser's responsibilities (as specified in such
advisory or sub-advisory contract) listed above.

<PAGE>
 
          (b) The Adviser's services shall be subject always to the control and
supervision of the Board, the restrictions of the Declaration of Trust and
Bylaws of the Trust, as amended from time to time, the provisions of the 1940
Act, the statements relating to each Fund's investment objective or objectives,
investment policies and investment restrictions as set forth in the then-current
Registration Statement, appropriate state insurance laws, and any applicable
provisions of the Internal Revenue Code of 1986, as amended (the "Code").  The
Trust has furnished or will furnish the Adviser with copies of the Registration
Statement, Declaration of Trust, and Bylaws as currently in effect and agrees
during the continuance of this agreement to furnish the Adviser with copies of
any amendments or supplements thereto before or at the time the amendments or
supplements become effective.  The Adviser will be entitled to rely on all
documents furnished by the Trust.

          (c) The Adviser represents that in performing investment advisory
services for each Fund, the Adviser shall make every effort to ensure that: (1)
each Fund shall comply with Section 817(h) of the Code, and the regulations
issued thereunder specifically Regulation Section 1.817-5, relating to the
diversification requirements for variable annuity, endowment, and life insurance
contracts, and any amendments or other modifications to such Section or
regulations; (2) each Fund continuously qualifies as a Regulated Investment
Company under Subchapter M of the Code or any successor provision; (3) each Fund
shall comply with any and all applicable state insurance law restrictions on
investments, and any changes thereto, that operate to limit or restrict the
investments that such Fund may otherwise make.  Except as instructed by the
Board, the Adviser shall also make decisions for the Trust as to the manner in
which voting rights, rights to consent to corporate action and any other rights
pertaining to the Trust's portfolio securities shall be exercised.  Should the
Board at any time make any determination as to investment policy and notify the
Adviser thereof, the Adviser shall be bound by such determination for the
period, if any, specified in such notice or until similarly notified that such
determination has been revoked.

          (d) In connection with the acquisition or disposition of securities
described in Section 2.2(a)(iv), the Adviser may place orders for the purchase
or sale of portfolio investments for the account of each Fund with brokers or
dealers selected by it and, to that end, the Adviser is authorized as the agent
of the Trust to give instructions to the custodian of the Trust as to deliveries
of securities and payments of cash for the account of each Fund.  In connection
with the selection of brokers or dealers and the placing of purchase and sale
orders with respect to assets of the Funds, the Adviser is directed at all times
to seek to obtain best execution and price within the policy guidelines
determined by the Board and set forth in the current Registration Statement.
Subject to this requirement and the provisions of the Advisers Act, the 1940
Act, the 1934 Act, and other applicable provisions of law, the Adviser may
select brokers or dealers with which it or the Trust is affiliated.

          (e) In addition to seeking the best price and execution, the Adviser

minimum commission rates available, if the Adviser determines in good faith that
such amount of commission is reasonable in relation to the value of the

disclosed in the Registration Statement.  The execution of such transactions
shall not be deemed to represent an unlawful act or breach of any duty created
by this agreement or otherwise.  The Adviser will periodically evaluate the
statistical data, research and other investment services provided to it by
brokers and dealers.  Such services may be used by the Adviser in connection
with the performance of its obligations under this agreement or in connection
with other advisory or investment operations including using such information in
managing its own accounts.

          (f) Nothing in this agreement shall preclude the aggregation of orders
for the sale or purchase of securities or other investments by two or more Funds
of the Trust or by the Trust and other separate accounts or other accounts
(collectively, "Advisory Clients") managed by the Adviser, provided that: (i)
the Adviser's actions with respect to the aggregation of orders for multiple
Advisory Clients, including the Trust, are consistent with the then-current
positions in this regard taken by the Securities and Exchange Commission or its
staff through releases, "no-action" letters, or otherwise; and (ii) the
Adviser's policies with respect to the aggregation of orders for multiple
Advisory Clients have been previously submitted and approved by the Board.

issued thereunder, specifically Regulation Section 1.817-5, relating to the
diversification requirements for variable annuity, endowment, and life insurance
contracts, and any amendments or other modifications to such Section or
regulations; (2) each Index Fund continuously qualifies as a Regulated
Investment Company under Subchapter M of the Code or any successor provision;
(3) each Index Fund shall comply with any and all applicable state insurance law
restrictions on investments, and any changes thereto, that operate to limit or
restrict the investments that such Index Fund may otherwise make. The Sub-
Adviser shall be obligated for compliance under clauses (1) and (3) of this
Section 2.1(c) only to the extent that the Trust has provided the Sub-Adviser
with notice, in writing, of the diversification requirements or state insurance
law restrictions applicable to the Index Funds, including a description thereof.
Except as instructed by the Board, the Sub-Adviser shall also make decisions for
the Index Funds as to the manner in which voting rights, rights to consent to
corporate action and any other rights pertaining to the Index Funds' portfolio
securities shall be exercised. Should the Board at any time make any
determination as to investment policy and notify the Sub-Adviser thereof in
writing, the Sub-Adviser, upon receipt of such notice, shall be bound by such
determination for the period, if any, specified in such written notice or until
similarly notified that such determination has been revoked.

             (d) In connection with the acquisition or disposition of securities
described in Section 2.1(a)(iv), the Sub-Adviser may place orders for the
purchase or sale of portfolio investments for the account of each Fund with
brokers or dealers selected by it and, to that end, the Sub-Adviser is
authorized as the agent of the Trust to give instructions to the custodians of
the Trust as to deliveries of securities and payments of cash for the account of
each Fund.  In connection with the selection of brokers or dealers and the
placing of purchase and sale orders with respect to assets of the Funds, the
Sub-Adviser is directed at all times to seek to obtain best execution and price.
Subject to this requirement and the provisions of the Advisers Act, the 1940
Act, the 1934 Act, and other applicable provisions of law, the Sub-Adviser may
select brokers or dealers with which it or the Trust or the Adviser is
affiliated.

             (e) In seeking the best price and execution, the Sub-Adviser may
also take into consideration research and statistical information and wire and
other quotation services provided by brokers and dealers to the Sub-Adviser. 
The Sub-Adviser is authorized to effect individual securities transactions at
commission rates in excess of the minimum commission rates available, if the 
Sub-Adviser determines in good faith that such amount of commission is
reasonable in relation to the value of the brokerage and research services
provided by such broker or dealer, viewed in terms of either that particular
transaction or Sub-Adviser's overall responsibilities with respect to the Index
Funds and its other clients and that the total commissions paid by each Index
Fund will be reasonable in relation to the benefits to the Index Fund over the
long term. The execution of such transactions shall not be deemed to represent
an unlawful act or breach of any duty created by this agreement or otherwise.
The Sub-Adviser will periodically evaluate the statistical data, research and
other investment

<PAGE>
 
services provided to it by brokers and dealers.  Such services may be used by
the Sub-Adviser in connection with the performance of its obligations under this
agreement or in connection with other advisory or investment operations
including using such information in managing its own accounts.

          (f) Nothing in this agreement shall preclude the aggregation of orders
for the sale or purchase of securities or other investments by two or more Funds
of the Trust or by the Trust and other separate accounts or other accounts
(collectively, "Advisory Clients") managed by the Sub-Adviser, provided that:
(i) the Sub-Adviser's actions with respect to the aggregation of orders for
multiple Advisory Clients, including the Trust, are consistent with the then-
current positions in this regard taken by the Securities and Exchange Commission
or its staff through releases, "no-action" letters, or otherwise; and (ii) the
Sub-Adviser's policies with respect to the aggregation of orders for multiple
Advisory Clients have been previously submitted and approved by the Board. The
Adviser and the Trust recognize that in some cases this procedure may adversely
affect the results obtained for an Index Fund.

     2.2  The Adviser shall retain the authority to establish and modify, from
time to time, the investment strategies and approaches to be followed by the
Sub-Adviser with respect to any Fund, subject, in all respects, to the
supervision and direction of the Trust's Board of Trustees and subject to
compliance with the investment objectives, policies and restrictions applicable
to such Fund as set forth in the Registration Statement, provided, however, that
the Sub-Adviser's duty under this agreement to act in conformity with any
document, instruction or guidelines produced by the Adviser shall not arise
until such document, instruction or guideline has been delivered to the Sub-
Adviser in writing.

                        Compensation of the Sub-Adviser

                     -----
international custody fees for such quarter and Y is equal to 0.02% of the
average daily net assets of the International Equity Index Fund during such
quarter plus $20 for each International Equity Index Fund portfolio transaction

to the following quarter and credited against the fee calculated pursuant to
this Section 3.1(a)(iii) for such quarter. The rates upon which the
International Equity Index Fund's fee shall be based are as follows:

                .35% of the first $50,000,000 of net assets
                .30% of the next $50,000,000 of net assets

          (b)   The Adviser shall be responsible for payment of, and the Sub-
Adviser agrees that it shall have no claim against the Trust or any Index Fund
respecting, the Sub-Adviser's compensation under this Agreement.

          (c)   During the term of this agreement, the Sub-Adviser will bear all

the agreement is in effect during the quarter and year respectively.

     3.3  If, pursuant to the Trust's Registration Statement and Declaration of
Trust, 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 of a share as last determined shall be deemed to be the net asset value of
a share as of the close of business on that day.

<PAGE>
 
     3.4  In connection with purchases or sales of portfolio securities for the
account of the Index Funds, neither the Sub-Adviser nor any officer, director,
shareholder or other affiliate of the Sub-Adviser shall: (i) act as agent and
accept any compensation other than its compensation provided for in this
agreement, except in the course of such person's business as an underwriter or
broker; or (ii) act as broker and accept any commission, fee, or other
remuneration in excess of the limits prescribed in the 1940 Act and the rules
promulgated thereunder.

its obligations and duties under this agreement, (ii) its reckless disregard of
its obligations and duties under this agreement; or (iii) a breach of Section

     THIS AGREEMENT is made and entered into this ____ day of __________, 1997,
by and between STATE FARM VARIABLE PRODUCT TRUST, a Delaware business trust (the
"Trust"), and STATE FARM INVESTMENT MANAGEMENT CORP., a Delaware corporation
(the "Underwriter").

     WHEREAS, the Trust is registered as an open-end management investment
company under the Investment Company Act of 1940, as amended (the "1940 Act");

     WHEREAS, the Trust issues shares of beneficial interest (the "Shares"), an
unlimited number of which are registered under the Securities Act of 1933, as
amended (the "1933 Act") pursuant to a registration statement initially filed
with the Securities and Exchange Commission (the "SEC") on February 27, 1997, as
amended from time to time (the "Registration Statement");

     WHEREAS, the Trust has established six separate series of Shares, each
corresponding to a separate investment portfolio having its own investment
objective, and may establish additional series of Shares in the future (such
existing and future series are collectively referred to herein as the "Funds");

     WHEREAS, the Shares are sold exclusively to certain segregated asset
accounts (the "Accounts") of State Farm Life Insurance Company or its affiliated
life insurance companies (collectively, "State Farm") to fund certain variable
annuity and/or life insurance contracts issued by State Farm (the "Contracts");

     WHEREAS, the Underwriter is a broker-dealer registered under the Securities
Exchange Act of 1934, as amended (the "1934 Act"), and a member of the National
Association of Securities Dealers, Inc. (the "NASD");

     WHEREAS, the Trust desires to retain the Underwriter to render certain
distribution services to each Fund in the manner and on the terms and conditions
set forth below; and

     WHEREAS, the Underwriter is willing to provide such distribution services
to each Fund in the manner and on the terms and conditions set forth below;

     NOW, THEREFORE, in consideration of their mutual promises, the Trust and

          1.1  The Trust hereby appoints the Underwriter its exclusive agent for
the distribution of the Shares of each Fund in jurisdictions wherein Shares may
legally be offered for sale and the Underwriter hereby accepts such appointment.

          1.2  The Underwriter agrees: (a) that it will use its best efforts
with reasonable promptness to sell such Shares exclusively to the Accounts at a
price equal to the net asset value of such Shares determined in accordance with
the Registration Statement; and (b) that the Trust shall receive 100% of such
sales price.

          1.3  Notwithstanding any other provision hereof, the Board of Trustees
of the Trust (the "Board") may refuse to sell shares of any Fund to the Company
and the Accounts, or suspend or terminate the offering of shares of any Fund if
such action is required by law or by regulatory authorities having jurisdiction
or is, in the sole discretion of the Board acting in good faith and in light of
its fiduciary duties under federal and any applicable state laws, necessary in
the best interests of the shareholders of such Fund.

          1.4  The Trust will furnish to the Underwriter from time to time such
information with respect to the Trust and its Shares as the Underwriter may
reasonably request for use in connection with the sale of Shares.  The
Underwriter agrees that it will not use or distribute or authorize the use,
distribution or dissemination by others in connection with the sale of Shares
any statements, other than those contained in the Registration Statement, except
such supplemental literature or advertising as shall be lawful under federal and
state securities laws and regulations, and that it will furnish the Trust with
copies of all such material.

          1.5  The Underwriter shall order Shares from the Trust only to the
extent that it shall have received purchase orders therefor.

state and federal laws relating to such sale and will indemnify and save
harmless the Trust from any damage or expense on account of any wrongful act by
the Underwriter or any employee, representative or agent of the Underwriter,
subject to the provisions of Section 3.1 herein.  The Underwriter will observe
and be bound by all the provisions of the Declaration or the Registration
Statement which at the time in any way require, limit, restrict, prohibit or
otherwise regulate any action on the part of the Underwriter.

           certain federal agencies (each, a "U.S. Securities System").

     2.2   Delivery of Securities.  The Trust on behalf of each Fund, by Proper

                delivered to the Custodian;

           6)   To the issuer thereof, or its agent, for transfer into the name

           all cash received by it from or for the account of the Trust, other

           by it to its credit as Custodian in such other banks or trust
           companies as it may in its discretion deem necessary or desirable;
           provided, however, that every such bank or trust company shall be
           qualified to act as a custodian under the Investment Company Act of
           1940 and that each such bank or trust company and the funds to be
           deposited with each such bank or trust company shall be approved by

           Trust and the Custodian in the amount of checks received in payment
           for Shares of the Fund which are deposited into the Trust's account.

     2.6   Collection of Income.  Subject to the provisions of Section 2.3, the
           --------------------                                                
           Custodian shall collect on a timely basis all income and other
           payments with respect to United States registered securities held
           hereunder to which the Trust on behalf of each Fund shall be entitled

           shall collect on a timely basis all income and other payments with
           respect to United States bearer securities if, on the date of payment
           by the issuer, such securities are held by the Custodian or its agent
           thereof and shall credit such income, as collected, to the Trust's
           custodian account. Without limiting the generality of the foregoing,
           the Custodian shall detach and present for payment all coupons and
           other income items requiring presentation as and when they become due
           and shall collect interest when due on securities held hereunder.

           the provisions of Section 2.2(10) shall be the responsibility of the
           Trust. The Custodian will have no duty or responsibility in
           connection therewith, other than to provide the Trust with such
           information or data as may be necessary to assist the Trust in
           arranging for the timely delivery to the Custodian of the income to
           which the Trust is properly entitled.

the Custodian shall not be responsible for the title, validity or genuineness of
any property or evidence of title thereto received by it or delivered by it
pursuant to this Contract and shall be held harmless by the Trust and/or each
Fund in acting upon any notice, request, consent, certificate or other
instrument reasonably believed by it to be genuine and to be signed by the
proper party or parties, including any futures commission merchant acting
pursuant to the terms of a three-party 

                                       10
<PAGE>
 
futures or options agreement. The Custodian shall be held to the exercise of
reasonable care in carrying out the provisions of this Contract, but shall be
kept indemnified by and shall be without liability to the Trust and/or the Fund
for any action taken or omitted by it without negligence. It shall be entitled
to rely on and may act upon advice of counsel (who may be counsel for the Trust)
on all matters, and shall be without liability for any action reasonably taken
or omitted pursuant to such advice.

     Except as may arise from the Custodian's own negligence or willful
misconduct, the Custodian shall be without liability to the Trust and/or each
Fund for any loss, liability, claim or expense resulting from or caused by; (i)
events or circumstances beyond the reasonable control of the Custodian or any
agent or nominee, including, without limitation, nationalization or
expropriation, imposition of currency controls or restrictions, the
interruption, suspension or restriction of trading on or the closure of any
securities market, power or other mechanical or technological failures or

similar events or acts; (ii) errors by the Trust in its instructions to the
Custodian, (iii) the insolvency of or acts or omissions by a Securities System;

other commercially prevalent payment or clearing system to deliver to the
custodian's sub-custodian or agent securities purchased or in the remittance or
payment made in connection with securities purchased or in the remittance or
payment made in connection with securities sold; (v) any delay or failure of any
company, corporation, or other body in charge of registering or transferring
securities in the name of the Custodian, the Trust, the Custodian's sub-
custodians, nominees or agents or any consequential losses arising out of such
delay or failure to transfer such securities including non-receipt of bonus,
dividends and rights and other accretions or benefits; (vi) delays or inability
to perform its duties due to any disorder in market infrastructure with respect
to any particular security or Securities System; and (vii) any provision of any
present or future law or regulation or order of the United States of America, or
any state thereof, or any other country, or political subdivision thereof or of
any court of competent jurisdiction.

     If the Trust request the Custodian to take any action with respect to
securities, which action involves the payment of money or which action may, in
the opinion of the Custodian, result in the Custodian or its nominee assigned to
the Trust being liable for the payment of money or incurring liability of some
other form, the Trust, as a prerequisite to requiring the Custodian to take such
action, shall provide indemnity to the Custodian in an amount and form
satisfactory to it.

     If the Trust requires the Custodian, its affiliates, subsidiaries or
agents, to advance cash or securities or provide conditional credit for any
purpose (including but not limited to securities settlements, and assumed
settlement) or in the event that the Custodian or its nominee shall incur or be
assessed any taxes, charges, expenses, assessments, claims or liabilities in
connection with the performance of this contract, except such as may arise from
its or its nominee's own negligent action, negligent failure to act or willful
misconduct, any property at any time held for the account of the Trust shall be
security therefor and should the Trust fail to repay the 

                                       11
<PAGE>
 
Custodian promptly, the Custodian shall be entitled to utilize available cash

reimbursement.

indirect, special or consequential damages.

happening of a like event at the direction of an appropriate regulatory agency
or court of competent jurisdiction.

office of the Custodian, duly endorsed and in the form for transfer, all
securities then held by it hereunder and shall transfer to an account of the
successor custodian all of the Trust's securities held in a Securities System.

     If the Board of Trustees fails to appoint a successor custodian on or
before the date when termination of this Contract shall become effective, then
the Custodian shall have the right to deliver to a bank or trust company, which
is a "bank" as defined in the Investment Company act of 1940, doing business in

surplus, and undivided profits, as shown by its last published report, of not
less than $25,000,000, all securities, funds and other properties held by the
Custodian and all instruments held by the Custodian relative thereto and all
other property held by it under this Contract and to transfer to an account of
such successor custodian all of the Trust's securities held in any securities
System.  Thereafter, such bank or trust company shall be the successor of the
Custodian under this Contract.

                                       12
<PAGE>
 
     In the event that securities, funds and other properties remain in the
possession of the Custodian after the date of termination hereof owing to
failure of the Board of Trustees to appoint a successor custodian, the Custodian
shall be entitled to fair compensation for its services during such period as
the Custodian retains possession of such securities, funds and other properties
and the provisions of this Contract relating to the duties and obligations of
the Custodian shall remain in full force and effect.

18.  SHAREHOLDER COMMUNICATIONS ELECTION

     Securities and Exchange Commission rule 14b-2 requires banks which hold
securities for the account of customers to respond to requests by issuers of
securities for the names, addresses and holdings of beneficial owners of
securities of that issuer held by the bank unless the 

                                       13
<PAGE>
 
beneficial owner has expressly objected to disclosure of this information. In
order to comply with the rule, the Custodian needs the Trust to indicate whether
it authorizes the Custodian to provide the trust's name, address, and share
position to requesting companies whose securities the Trust holds on behalf of
the Fund. If the Trust tells the Custodian "yes" or does not check either "yes"
or "no" below, the Custodian is required by the rule to treat the Trust as
consenting to disclosure of this information for all securities held by the
Trust on behalf of the Fund. For the Trust's protection, the rule prohibits the
requesting company from using the Trust's name and address for any purpose other
than corporate communications. Please indicate below whether the Trust consents
or objects by checking one of the alternatives below.

      YES       [_]        The Custodian is authorized to 
                           release the Trust's name, address, 
                           and share positions.

      NO        [_]        The Custodian is not authorized to 
                           release the Trust's name, address,

its nominee shall incur or be assessed any taxes, charges, expenses,
assessments, claims or liabilities in connection with the performance of this
Contract, except such as may arise from its or its nominee's own negligent
action, negligent failure to act or willful misconduct, any property at any time
held for the account of the Trust shall be security therefor and should the
Trust fail to repay the Custodian promptly, the Custodian shall be entitled to
utilize available cash and to dispose of the Trust's assets to the extent
necessary to obtain reimbursement.

hold pursuant to the provisions hereof, in a separate account or accounts and

Portfolio Securities which may nor or hereafter be delivered to it by or for the
account of the Fund.  All such Portfolio Securities will be held or disposed of

herein relating to Portfolio Securities that are not physically held by the
Bank, the Bank will register all Portfolio Securities (unless otherwise directed
by Proper Instructions or an Officers' Certificate), in the name of a registered
nominee of the Bank as defined in the Internal Revenue Code and any Regulations
of the Treasury Department issued thereunder, and will execute and deliver all
such certificates in connection therewith as may be required by such laws or
regulations or under the laws of any state.

          The Fund will from time to time furnish to the Bank appropriate

with proper Instructions or an Officers' Certificate.  The Bank will execute and
deliver, or cause to be executed and delivered, to the Fund all notices, proxies
and proxy soliciting materials delivered to the Bank with respect to such
Securities, such proxies to be executed by the registered holder of such
Securities (if registered otherwise than in the name of the Fund), but without
indicating the manner in which such proxies are to be voted.

          6.3  Corporate Action.  If at any time the Bank is notified that an

reorganization, reclassification, subdivision, combination, stock split or stock
dividend, which Corporate Action requires an affirmative response or action on
the part of the holder of such Portfolio Security (a "Response"), the Bank shall
notify the Fund promptly of the Corporate Action, the Response required in
connection with the Corporate Action and the bank's deadline for receipt from
the Fund of Proper Instructions regarding the Response (the "response
Deadline").  The Bank shall forward to the Fund via telecopier and/or overnight
courier all notices, information statements or other materials relating to the
corporate Action within twenty-four (24) hours of receipt of such materials by
the Bank.

receipt by the Bank of proper Instructions from the Fund no later than 5:00 p.m.

Securities, consents and other materials no later than 5:00 p.m. on the date
specified as the Response Deadline.

               (b) The Bank shall have no duty to act upon a required Response
if Proper Instructions relating to such Response and all necessary Securities,
consents and other materials are not received by and in the possession of the
Bank no later than 5:00 p.m. on the date specified as the Response Deadline.
Notwithstanding, the Bank may, in its sole discretion, use its best efforts to
act upon a Response for which Proper Instructions and/or necessary securities,
consents or other materials are received by the Bank after 5:00 p.m. on the date
specified as the Response Deadline, it being acknowledged and agreed by the
parties that any undertaking by the Bank to use its best efforts in such
circumstances shall in no way create any duty upon the Bank to complete such
Response prior to its expiration.

               (c) In the event that the Fund notifies the Bank of a Corporate
Action requiring a Response and the Bank has received no other notice of such
Corporate Action, the Response Deadline shall be 48 hours prior to the Response
expiration time set by the depository processing such Corporate Action.

               (d) Section 14.3(g) of this Agreement shall govern any Corporate
Action involving Foreign Portfolio Securities held by a Selected Foreign Sub-
Custodian.

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

        12.1  Fund Evaluation. The Bank shall compute and, unless otherwise
              ---------------

York Stock Exchange on each day on which said Exchange is open for unrestricted

stock of the Fund, such determination to be made in accordance with the
provisions of the Articles and By-laws of the Fund and the Prospectus and
Statement of Additional Information relating to the Fund, as they may from time
to time be amended, and any applicable resolutions of the Board at the time in
force and applicable; and promptly to notify the Fund, the proper exchange and
the NASD or such other persons as the Fund may request of the results of such
computation and determination. In computing the net asset value hereunder, the
Bank may rely in good faith upon information furnished to it by any Authorized
Person in respect of (i) the manner of accrual of the liabilities of the Fund
and in respect of liabilities of the Fund not appearing on its books of account
kept by the Bank, (ii) reserves, if any, authorized by the Board or that no such
reserves have been authorized, (iii) the source of the quotations to be used in
computing the net asset value, (iv) the value to be assigned to any security for
which no price quotations are available, and (v) the method of computation of
the public offering price on the basis of the net asset value of the shares and
the Bank shall not be responsible for any loss

                                      16

promulgated by the Securities and Exchange Commission, and any subsequent

to the terms set forth below:

             (a) The Bank shall compute the Yield Calculation for the Fund for
the stated periods of time as shall be mutually agreed upon, and communicate in
a timely manner the result of such computation to the Fund.

             (b) In performing the Yield Calculation, the Bank will derive the
items of data necessary for the computation from the records it generates and

with respect to the accuracy or correctness of any such data supplied to it by
the Fund, any of the Fund's designated agents or any of the Fund's designated
third party providers.

Bank shall be entitled to rely on, written standards and guidelines to be

forth in the Releases or any Subsequent Staff Positions as they specifically
apply to the Fund. In the event that the computation methods in the Releases or
the Subsequent Staff Positions or the application to the Fund of a standard or
guideline is not free from doubt or in the event there is any question of
interpretation as to the characterization of a particular security or any aspect
of a security or a payment with respect thereto (e.g., original issue discount,
participating debt security, income or return of capital, etc.) or otherwise or
as to any other element of the computation which is pertinent to the Fund, the
Fund or its designated agent shall have the full responsibility for making the
determination of how the security or payment is to be treated for purposes of
the computation and how the computation is to be made and shall inform the Bank
thereof on a timely basis. The Bank shall have no responsibility to make
independent determinations with respect to any item which is covered by this
Section, and shall not be responsible for its computations made in accordance
with such determinations so long as such computations are mathematically
correct.

             (d) The Fund shall keep the Bank informed of all publicly available
information and of any non-public advice, or information obtained by the Fund
from its independent auditors or by its personnel or the personnel of its
investment adviser, or Subsequent Staff Positions related to the computations to
be undertaken by the Bank pursuant to this Agreement and the Bank shall not be
deemed to have knowledge of such information (except as contained in the
Releases) unless it has been furnished to the Bank in writing.

employ such sub-custodian as soon as alternate custodial arrangements have been
implemented.

              (b) Foreign Securities Depositories.  Except as may otherwise be
                  -------------------------------
agreed upon in writing by the Bank and the Fund, assets of the Fund shall be

Fund (each, a "Foreign Sub-Custodian Agreement") shall be substantially in the
form provided to the Fund and shall provide that: (a) the Fund's assets will not
be subject to any right, charge, security interest, lien or claim of any kind in

limitation, any fees or taxes payable upon transfers or reregistration of
securities); (b) beneficial ownership of the Fund's assets will be freely

assets of the Fund held by the Selected Foreign Sub-Custodian will be subject
only to the instructions of the Bank or its agents.

of the nominee of the Selected Foreign Sub-Custodian, the Fund agrees to hold
any such nominee harmless from any liability by reason of the registration of
such securities in the name of such nominee.

and payment for Foreign Portfolio Securities received for the account of the
Fund and delivery of Foreign Portfolio Securities maintained for the account of
the Fund may be effected in accordance with the customary established securities
trading or securities processing practices and procedures in the jurisdiction or
market in which the transaction occurs, including, without limitation,

delivering securities to the purchaser thereof or to a dealer therefor (or an
agent for such purchaser or dealer) against a receipt with the expectation of
receiving later payment for such securities from such purchaser or dealer.

    In connection with any action to be taken with respect to the Foreign
Portfolio Securities held hereunder, including, without limitation, the exercise
of any voting rights, subscription rights, redemption rights, exchange rights,
conversion rights or tender rights, or any other action in connection with any
other right, interest or privilege with respect to such Securities
(collectively, the "Rights"), the Bank shall promptly transmit to the Fund such
information in connection therewith as is made available to the Bank by the
Foreign Sub-Custodian, and shall promptly forward to the applicable Foreign Sub-
Custodian any instructions, forms or certifications with respect to such Rights,
and any instructions relating to the actions to be taken in connection
therewith, as the Bank shall receive from the Fund pursuant to Proper
Instructions. Notwithstanding the foregoing, the Bank shall have no further duty
or obligation with respect to such Rights, including, without limitation, the
determination of whether the Fund is entitled to participate in such Rights
under applicable U.S. and foreign laws, or the determination of whether any
action proposed to be taken with respect to such Rights by the Fund or by the
applicable Foreign Sub-Custodian will comply with all applicable terms and
conditions of any such Rights or any applicable laws or regulations, or market
practices within the market in which such action is to be taken or omitted.

              (h) Liability of Selected Foreign Sub-Custodians.  Each Foreign
                  --------------------------------------------
Sub-Custodian Agreement with a foreign banking institution shall require the
institution to exercise reasonable care in the performance of its duties and to
indemnify, and hold harmless, the Bank and each Fund from and against certain
losses, damages, costs, expenses, liabilities or claims arising out of or in
connection with the institution's performance of such obligations, all as set
forth in the applicable Foreign Sub-Custodian Agreement. The Fund acknowledges
that the Bank, as a participant in Euro-clear, is subject to the Terms and
Conditions Governing the Euro-Clear System, a copy of which has been made
available to the Fund. The Fund acknowledges that pursuant to such Terms and
Conditions, Morgan Guaranty Brussels shall have the sole right to exercise or
assert any and all rights or claims in respect of actions or omissions of, or

custodian utilized by Euro-clear in connection with the Fund's securities and

to the Fund information concerning the Selected Foreign Sub-Custodians employed
hereunder for use by the Fund in evaluating such Selected Foreign Sub-Custodians
to ensure compliance with the requirements of Rule 17f-5 of the Act. In
addition, the Bank will promptly inform the Fund in the event that the Bank is
notified by a Selected Foreign Sub-Custodian that there appears to be a
substantial likelihood that its shareholders' equity will decline below US$200
million (or the equivalent thereof) or that its shareholders' equity has
declined below US$200 million (in each case computed in accordance with
generally accepted U.S. accounting principles) or any other capital adequacy
test applicable to it by exemptive order, or if the Bank has actual knowledge of
any material loss of the assets of the Fund held by a Foreign Sub-Custodian.

responsibility of the Fund to notify the Bank of the obligations imposed on the
Fund or the Bank as the custodian of the Fund by the tax law of any non-U.S.
jurisdiction, including responsibility for withholding and other taxes,
assessments or other governmental charges, certifications and governmental
reporting. The sole responsibility of the Selected Foreign Sub-custodian with
regard to such tax law shall be to use reasonable efforts to assist the Fund
with respect to any claim for exemption or refund under the tax law of
jurisdictions for which the Fund has provided such information.

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

expenses and charges made or incurred by the Bank in the performance of this
Agreement (including any duties listed on any Schedule hereto, if any) including
any indemnities for any loss, liabilities or expense to the Bank as provided
above. For the services rendered by the Bank hereunder, the Fund will pay to the
Bank such compensation or fees at such rate and at such times as shall be agreed
upon in writing by the parties from time to time. The Bank will also be entitled
to reimbursement by the Fund for all reasonable expenses incurred in conjunction
with termination of this Agreement.

        14.6  Advances by the Bank. The Bank may, in its sole discretion,
              --------------------                                       
advance funds on behalf of the Fund to make any payment permitted by this
Agreement upon receipt of any proper authorization required by this Agreement
for such payments by the Fund. Should such a payment or payments, with advanced
funds, result in an overdraft (due to insufficiencies of the Fund's account with
the Bank, or for any other reason) this Agreement deems any such overdraft or
related indebtedness a loan made by the Bank to the Fund payable on demand. Such
overdraft shall bear interest at the current rate charged by the Bank for such
loans unless the Fund shall provide the Bank with agreed upon compensating
balances. The Fund agrees that the Bank shall have a continuing lien and
security interest to the extent of any overdraft or indebtedness, in and to any
property at any time held by it for the Fund's benefit or in which the Fund has
an interest and which is then in the Bank's possession or control (or in the
possession or control of any third party acting on the Bank's behalf). The Fund
authorizes the Bank, in the Bank's sole discretion, at any time to charge any
overdraft or indebtedness, together with interest due thereon, against any
balance of account standing to the credit of the Fund on the Bank's books.

     16.  Termination.
          ----------- 

          16.1  The term of this Agreement shall be three years commencing upon
the effective date of the Fund's registration statement (the "Initial Term"),
unless earlier terminated as provided herein. After the expiration of the
Initial Term, the term of this Agreement shall automatically renew for
successive one-year terms (each a "Renewal Term") unless notice of non-renewal
is delivered by the non-renewing party to the other party no later than sixty
days prior to the expiration of the Initial Term or any Renewal Term, as the
case may be.

                (a) Either party hereto may terminate this Agreement prior to
the expiration of the Initial Term in the event the other party violates any
material provision of this Agreement, provided that the non-violating party
gives written notice of such violation to the violating party and the violating
party does not cure such violation within 90 days of receipt of such notice.

                (b) Either party may terminate this Agreement during any Renewal
Term upon sixty days written notice to the other party. Any termination pursuant
to this paragraph 16.1 (b) shall be effective upon expiration of such sixty
days, provided, however, that the effective date of such termination may be
postponed to a date not more than ninety days after delivery of the written
notice: (i) at the request of the Bank, in order to prepare for the transfer by
the Bank of all of the assets of the Fund held hereunder; or (ii) at the request
of the Fund, in order to give the Fund an opportunity to make suitable
arrangements for a successor custodian

          16.2  In the event of the termination of this Agreement, the Bank will
immediately upon receipt or transmittal, as the case may be, of notice of
termination, commence and prosecute diligently to completion the transfer of all
cash and the delivery of all Portfolio Securities duly endorsed and all records
maintained under Section 11 to the successor custodian when appointed by the
Fund. The obligation of the Bank to deliver and transfer over the assets of the
Fund held by it directly to such successor custodian will commence as soon as
such successor is appointed and will continue until completed as aforesaid. If
the Fund does not select a successor custodian within ninety (90) days from the
date of delivery of notice of termination the Bank may, subject to the
provisions of subsection (16.3), deliver the Portfolio Securities and cash of
the Fund held by the Bank to a bank or trust company of the Bank's own selection
which meets the requirements of Section 17(f)(1) of the 1940 Act and has a
reported capital, surplus and undivided profits aggregating not less than
$2,000,000, to be held as the property of the Fund under terms similar to those
on which they were held by the Bank, whereupon such bank or trust company so
selected by the Bank will become the successor custodian of such assets of the
Fund with the same effect as though selected by the Board. Thereafter, the Bank
shall be released from any and all obligations under this Agreement.

                                      24
<PAGE>
 
          16.3  Prior to the expiration of ninety (90) days after notice of
termination has been given, the Fund may furnish the Bank with an order of the
Fund advising that a successor custodian cannot be found willing and able to act
upon reasonable and customary terms and that there has been submitted to the
shareholders of the Fund the question of whether the Fund will be liquidated or
will function without a custodian for the assets of the Fund held by the Bank.
In that event the Bank will deliver the Portfolio Securities and cash of the
Fund held by it, subject as aforesaid, in accordance with one of such
alternatives which may be approved by the requisite vote of shareholders, upon
receipt by the Bank of a copy of the minutes of the meeting of shareholders at
which action was taken, certified by the Fund's Secretary and an opinion of
counsel to the Fund in form and content satisfactory to the Bank. Thereafter,
the Bank shall be released from any and all obligations under this Agreement.

          16.4  The Fund shall reimburse the Bank for any reasonable expenses
incurred by the Bank in connection with the termination of this Agreement.

          16.5  At any time after the termination of this Agreement, the Fund
may, upon written request, have reasonable access to the records of the Bank
relating to its performance of its duties as custodian.

     17.  Confidentiality.  Both parties hereto agree than any non-public

may not be disclosed without the consent of the other party, except as may be
required by applicable law or at the request of a governmental agency. The

to all other remedies at law or in equity to an injunction or injunctions
without bond or other security to prevent breaches of this provision.

     18.  Notices.  Any notice or other instrument in writing authorized or

                            PARTICIPATION AGREEMENT

     THIS AGREEMENT is made and entered into this ___ day of ________, 1997 by
and between STATE FARM LIFE INSURANCE COMPANY, an Illinois corporation (the
"Company"), on its own behalf and on behalf of the segregated asset accounts of
the Company set forth on Schedule A attached hereto (each, an "Account";
collectively, the "Accounts"), STATE FARM VARIABLE PRODUCT TRUST, a Delaware
business trust (the "Trust"), and STATE FARM INVESTMENT MANAGEMENT CORP., a
Delaware corporation ("SFIM").

     WHEREAS, the Trust is registered as an open-end management investment
company under the Investment Company Act of 1940, as amended (the "1940 Act");

     WHEREAS, the Trust issues shares of beneficial interest (the "Shares")
registered under the Securities Act of 1933, as amended (the "1933 Act")
pursuant to a registration statement initially filed with the Securities and
Exchange Commission on February 27, 1997, as amended from time to time (the
"Registration Statement");

     WHEREAS, the Trust has established six separate series of Shares, each
corresponding to a separate investment portfolio having its own investment
objective, and may establish additional series of Shares in the future (such
existing and future series are collectively referred to herein as the "Funds");

     WHEREAS, the Trust is available to act as the investment vehicle for the
Accounts, and other separate accounts established in connection with variable
life insurance policies and variable annuity contracts issued by the Company and
its affiliates (the "Contracts");

     WHEREAS, the Accounts are duly organized, validly existing segregated asset
accounts, established by resolutions of the Board of Directors of the Company,
to set aside and invest assets attributable to the Contracts that are allocated
to the Accounts (the Contracts and the Accounts covered by this agreement, and
the corresponding Funds covered by this agreement in which the Accounts invest,
are specified in Schedule A attached hereto as may be modified from time to
time);

     WHEREAS, the Company has registered the Accounts as unit investment trusts
under the 1940 Act;

     WHEREAS, SFIM, the Trust's investment adviser and principal underwriter, is
an investment adviser registered under the Investment Advisers Act of 1940, as

<PAGE>
 
     WHEREAS, to the extent permitted by applicable insurance laws and
regulations, the Trust, either directly or in conjunction with SFIM as its
principal underwriter, intends to make a continuous offering of its shares at
net asset value, and the Company has and intends to purchase the shares of the
Funds on behalf of the Accounts to fund the Contracts;

     NOW, THEREFORE, in consideration of their mutual promises, the Company, the
Trust, and SFIM agree as follows:


                                   ARTICLE 1
                             Sale of Trust Shares

     1.1  The Trust and SFIM agree to sell to the Company those shares of the
Trust which the Accounts order, executing such orders on a daily basis at the
net asset value next computed after receipt by the Trust, SFIM, or their
designee for the order of the shares of the Trust.  For purposes of this Section
1.1, the Company shall be the Trust's and SFIM's designee for receipt of such
orders from Contract owners and receipt by the Company shall constitute receipt
by the Trust and SFIM; provided, that either the Trust or SFIM receives notice
of such order by 7:30 a.m. Chicago time on the next following Business Day.
"Business Day" shall mean any day on which the New York Stock Exchange is open
for trading and on which the Trust calculates its net asset value pursuant to
the rules of the Securities and Exchange Commission (the "SEC").

     1.2  The Trust and SFIM agree to make Trust shares available indefinitely
for purchase at the applicable net asset value per share by the Company and the
Accounts on those days on which the Trust calculates its net asset value
pursuant to rules of the SEC.  The Trust shall use reasonable efforts to
calculate its net asset values on the days and at the times described in the
Trust's prospectus (as of the date hereof, as of the close of the New York Stock
Exchange on each day on which the New York Stock Exchange is open for trading,
but not on the Friday following Thanksgiving nor on December 26, 1997).
Notwithstanding the foregoing, the Board of Trustees of the Trust (the "Board")
may refuse to sell shares of any Fund to the Company and the Accounts, or
suspend or terminate the offering of shares of any Fund if such action is
required by law or by regulatory authorities having jurisdiction or is, in the
sole discretion of the Board acting in good faith and in light of its fiduciary
duties under federal and any applicable state laws, necessary in the best
interests of the shareholders of such Fund.

     1.3  The Trust and SFIM agree that shares of the Trust will be sold to the
Company and the Accounts.  In addition, shares of the Trust may be sold to other
insurance companies affiliated with the Company or their separate accounts.
Shares will not be sold to natural persons.  Nothing herein shall prohibit the
Company from establishing separate accounts or sub-accounts other than the
Accounts which purchase shares from investment companies   other than the Trust.

<PAGE>
 
     
     1.4  The Company shall pay for the Trust shares in federal funds
transmitted by wire on the next Business Day after an order to purchase shares
is made in accordance with the provisions of Section 1.1 hereof.  For purpose of
Section 2.8, upon receipt by the Trust of the federal funds so wired, such funds
shall cease to be the responsibility of the Company and shall become the
responsibility of the Trust.  The amount of redemption proceeds payable pursuant
to Section 1.6 may be credited toward any purchase payments due pursuant to this
Section 1.4.     

     1.5  The Trust agrees to redeem for cash, on the Company's request, any
full or fractional shares of the Trust held by the Company, executing such
requests on a daily basis at the net asset value next computed after receipt by
the Trust or its designee of the request for redemption.  For purposes of this
Section 1.5, the Company shall be the designee of the Trust for receipt of
requests for redemption from Contract owners and receipt by such designee shall
constitute receipt by the Trust; provided, that the Trust receives notice of
such request for redemption by 7:30 a.m. Chicago time on the next following
Business Day.
    
     1.6  Payment of redemption proceeds will be in federal funds transmitted by
wire on the same Business Day the Trust receives notice of the redemption order
from the Company.  The Trust reserves the right to delay payment of redemption
proceeds, but in no event may such payment be delayed longer than the period
permitted by the 1940 Act.  If notification of redemption is received after 7:30
a.m. Chicago time, payment for redeemed shares will be made on the next
following Business Day.  For purpose of Section 2.8, upon receipt by the Company
of the federal funds so wired, such funds shall cease to be the responsibility
of the Trust and shall become the responsibility of the Company; the Trust will
not bear any responsibility whatsoever for the proper disbursement or crediting
of redemption proceeds.  Purchase payments payable pursuant to Section 1.4 may
be credited toward any amounts of redemption proceeds due pursuant to this
Section 1.6.     

     1.7  Unless otherwise determined by the Board, issuance and transfer of the
Trust's shares will be by book entry only and share certificates will not be
issued to the Company or the Accounts.  Shares ordered from the Trust will be
recorded in an appropriate title for the Accounts or the appropriate subaccounts
of the Accounts.

     1.8  The Trust shall furnish same day notice (by wire or telephone followed
by written confirmation) to the Company of any income, dividends or capital gain
distributions payable on the Trust's shares.  The Company hereby elects to
receive all such dividends and distributions as are payable on the Fund shares
in additional shares of that Fund.  The Trust shall notify the Company of the
number of shares so issued as payment of such dividends and distributions.

     1.9  The Trust or its custodian shall make the net asset value per share
for each Fund available to the Company on each Business Day as soon as
reasonably practical after the net asset value per share is calculated and shall
use its best efforts to make such net asset value per share available by 6:00
p.m. Chicago time.

                                   ARTICLE 2
                        Representations and Warranties

     2.1  The Company represents and warrants that the Contracts are or will be
registered under the 1933 Act, and that the Contracts will be issued, sold, and
distributed in material compliance with all applicable state and federal laws,
including without limitation the 1933 Act, the 1934 Act, and the 1940 Act.  The
Company further represents and warrants that it is an insurance company duly
organized and in good standing under applicable law, that it has legally and
validly established the Accounts as segregated asset accounts under Illinois
law, and that it has registered the Accounts as unit investment trusts in
accordance with the provisions of the 1940 Act (unless exempt therefrom) to
serve as segregated investment accounts for the Contracts and that it will
maintain such registrations for so long as any Contracts are outstanding.  The
Company shall amend the registration statements under the 1933 Act for the
Contracts and the registration statements under the 1940 Act for the Accounts
from time to time as required in order to effect the continuous offering of the
Contracts or as may otherwise be required by applicable law.  The Company shall
register and qualify the Contracts for sale in accordance with the securities
laws of the various states only if and to the extent deemed necessary by the
Company.

     2.2  The Company represents that it believes, in good faith, that the
Contracts are currently and at the time of issuance will be treated as life
insurance, endowment or annuity contracts under applicable provisions of the
Internal Revenue Code of 1986, as amended (the "Code"), that it will make every
effort to maintain such treatment and that it will notify the Trust immediately
upon having a reasonable basis for believing that the Contracts have ceased to
be so treated or that they might not be so treated in the future.

     2.3  The Trust and SFIM represent and warrant that Trust shares sold
pursuant to this agreement shall be registered under the 1933 Act, duly
authorized for issuance and sold in material compliance with the laws of
Delaware and all applicable federal and state securities laws.  The Trust
further represents that it is and shall remain registered under the 1940 Act,
and that it shall amend the Registration Statement for its shares under the 1933
Act and the 1940 Act from time to time as required in order to effect the
continuous offering of its shares.  The Trust shall register and qualify the
shares for sale in accordance with the laws of the various states, including
those states designated by SFIM pursuant to its underwriting agreement with the
Trust, only if and to the extent deemed advisable by the Trust.

     2.4  The Trust represents that each Fund of the Trust is currently
qualified or will be qualified as a Regulated Investment Company under
Subchapter M of the Code and that every effort will be made to maintain such
qualification (under Subchapter M or any successor or similar provision) and
that the Trust will notify the Company orally (followed by written notice) or by
wire immediately upon having a reasonable basis for believing that any Fund of
the Trust has ceased to so qualify or that any Fund might not so qualify in the
future.

<PAGE>
 
     2.5  The Trust currently does not intend to make any payments to finance
distribution expenses pursuant to Rule 12b-1 under the 1940 Act or otherwise,
although it may make such payments in the future.  However, if the Trust were
authorized to establish a 12b-1 plan, the Trust would undertake to have the
Board, of which a majority of trustees are not interested persons, as defined in
the 1940 Act, of the Trust, formulate and approve any plan under Rule 12b-1 to
finance distribution expenses.

     2.6  The Trust represents that it is lawfully organized and validly
existing under the laws of the State of Delaware and that it does and will
comply in all material respects with the 1940 Act.

     2.7  SFIM represents that it is and shall remain duly registered as an
investment adviser and broker-dealer under all applicable federal and state
securities laws at all times when it is the Trust's investment adviser and
principal underwriter and that it shall perform its obligations for the Trust in
material compliance with any applicable state and federal securities laws and
NASD rules and regulations relating to broker-dealers.

     2.8  The Trust, SFIM, and the Company each represents and warrants that all
of its directors, trustees, officers, employees, investment advisers, and other
individuals or entities dealing with the money and/or securities of the Trust
are and shall continue to be at all times covered by a blanket fidelity bond or
similar coverage for the benefit of the Trust in an amount not less than the
minimal coverage as required currently by Section 17(g) and Rule 17g-1 of the
1940 Act or related provisions as may be promulgated from time to time.  The
aforesaid bond shall include coverage for larceny and embezzlement and shall be
issued by a reputable bonding company.


                                   ARTICLE 3
                    Prospectus and Proxy Statements; Voting

     3.1  At least annually, the Trust shall, at its expense or at the expense
of SFIM, as appropriate, provide the Company, free of charge, with as many
copies of the Trust's current prospectus as the Company may reasonably request
for distribution to both existing Contract owners and prospective purchasers.
If requested by the Company in lieu thereof, the Trust shall provide such
documentation (including a final "camera ready" copy of the new prospectus as
set in type at the Trust's expense) and other assistance as is reasonably
necessary in order for the parties hereto once each year (or more frequently if
the prospectus for the Trust is supplemented or amended) to have the prospectus
for the Contracts and the Trust's prospectus printed together in one document;
the expenses of such printing to be apportioned between the Company and the
Trust (or SFIM, if appropriate) in proportion to the number of pages of the
Contract and Trust prospectuses, taking account of other relevant factors
affecting the expense of printing, such as columns, charts, etc.; the Trust or
SFIM will bear the cost of printing the Trust's portion of such document, and
the Company will bear the expenses of printing the Accounts' portion of such
document.

<PAGE>
 
     3.2  The Trust's prospectus shall state that the Statement of Additional
Information ("SAI") for the Trust is available from the Trust.  The Trust, at
its expense or at the expense of SFIM, as appropriate, shall print and provide
the SAI to the Company (or a master of the SAI suitable for duplication by the
Company) for any Contract owner or prospective purchaser who requests the SAI.
The Company shall provide the SAI to any Contract owner or prospective purchaser
who requests it.

     3.3  The Trust (or SFIM, as appropriate), at its expense, shall provide the
Company with copies of its proxy material, reports to shareholders and other
communications to shareholders in such quantity as the Company shall reasonably
require for distribution to Contract owners.

     3.4  The Company shall: (a) solicit voting instructions from Contract
owners; (b) vote the Trust shares in accordance with instructions received from
Contract owners; and (c) vote Trust shares for which no instructions have been
received in the same proportion as Trust shares of such Fund for which
instructions have been received.  The Company reserves the right to vote Trust
shares held in the Accounts in its own right, to the extent permitted by law.

     3.5  The process of soliciting Contract owners' voting instructions,
tabulating votes, and other shareholder voting procedures shall be conducted in
accordance with procedures adopted by the Company.


                                   ARTICLE 4

Trust or its designee object to such use within five (5) Business Days after
receipt of such material.

     4.2  The Company shall not give any information or make any representations
or statements on behalf of the Trust or concerning the Trust in connection with
the sale of the Contracts other than the information or representations
contained in the registration statement or prospectus for the Trust shares, as
such registration statement and prospectus may be amended or supplemented from
time to time, or in reports or proxy statements for the Trust which are in the
public domain or approved by the Trust for distribution to Contract owners, or
in sales literature or other promotional material approved by the Trust or its
designee, except with the permission of the Trust.  The Trust or its designee
agrees to respond to any request for approval on a prompt and timely basis.

<PAGE>
 
     4.3  The Trust shall furnish, or shall cause to be furnished, to the
Company or its designee, each piece of sales literature or other promotional
material in which the Company and/or the Accounts is named, at least five (5)
Business Days prior to its use by the Trust.  No such material shall be used by
the Trust if the Company or its designee object to such use within five (5)
Business Days after receipt of such material.

     4.4  The Trust shall not give any information or make any representations
on behalf of the Company or concerning the Company, the Accounts, or the
Contracts other than information or representations contained in a registration
statement or prospectus for the Contracts, as such registration statement and
prospectus may be amended or supplemented from time to time, or in reports for
the Accounts which are in the public domain or approved by the Company for
distribution to Contract owners, or in sales literature or other promotional
material approved by the Company or its designee, except with the permission of
the Company.  The Company or its designee agrees to respond to any request for
approval on a prompt and timely basis.

     4.5  The Company and the Trust may each request that the other provide at
least one complete copy of all registration statements, prospectuses, SAIs,
reports, proxy statements, sales literature and other promotional materials,
applications for exemptions, requests for "no-action" letters, and all
amendments to any of the above, that relate to the Contracts, or to the Trust or
its shares, prior to or contemporaneously with the filing of such document with
the SEC or other regulatory authority.  The Company or Trust shall also each
promptly inform the other of the results of any examination by the SEC (or other
regulatory authority) that relates to the Contracts, the Trust or its shares,
and the party that was the subject of the examination shall provide the other
party with a copy of any "deficiency letter" or other correspondence or written
report regarding any such examination.

     4.6  For purposes of this Article 4, the phrase "sales literature or other
promotional material" means advertisements (defined as material published, or
designed for use in, a newspaper, magazine, or other periodical, radio,
television, telephone or tape recording, videotape display, signs or billboards,
motion pictures, telephone directories (other than routine listings), electronic
or other public media), sales literature (defined as any written or electronic
communication distributed or made generally available to customers or the public
that is not an advertisement as defined above, including, but not limited to,
circulars, research reports, market letters, performance reports or summaries,
form letters, telemarketing scripts, seminar texts, and reprints or excerpts of
any other advertisement, sales literature or published article), and educational

                               Fees and Expenses

     5.1  No party hereto shall pay any fee or other compensation to any other
party hereto pursuant to this agreement, except that if the Trust or any Fund
adopts and implements a plan pursuant to Rule 12b-1 under the 1940 Act to
finance distribution expenses, then, subject to obtaining any regulatory
approvals, the Trust may make payments to the Company, SFIM, or the Company's
principal underwriter for the Contracts if and in amounts agreed to by the Trust
in writing.

     5.2  Each party shall reimburse each other party for expenses initially
paid by such other party but allocated to it in accordance with any allocation
of expenses specified in Article 3 hereof.


                                   ARTICLE 6
                    Diversification and Related Limitations

     6.1  Subject to the Company's obligations under Section 2.2 hereof, the
Trust and SFIM each represent and warrant that the Trust will at all times
invest its assets in such a manner as to ensure that the Contracts will be
treated as annuity, endowment, or life insurance contracts under the Code and
the regulations issued thereunder.  Without limiting the scope of the foregoing,
the Trust and SFIM will at all times ensure that the Trust complies with Section
817(h) of the Code and Treas. Reg. (S) 1.817-5, as amended from time to time,
and any Treasury interpretations thereof, relating to the diversification
requirements for variable annuity, endowment, or life insurance contracts and
any amendments or other modifications to such Section or Regulations.

     6.2  Trust shares will not be sold to any person or entity that would
result in the Contracts not being treated as annuity, endowment, or life
insurance contracts, in accordance with the statutes and regulations referred to
in Section 6.1 hereof.


                                   ARTICLE 7
                         Potential Material Conflicts

     7.1  The Board shall monitor each Fund of the Trust for the existence of
any material irreconcilable conflict between the interests of the variable
annuity contract owners and the variable life policy owners of the Company
and/or affiliated companies (collectively, "contract owners") investing
indirectly in the Trust.  The Trust represents that at all times at least a
majority of the trustees of the Trust shall not be interested persons, as
defined in the 1940 Act (the "disinterested trustees").  The Board shall have
the sole authority to determine if a material irreconcilable conflict exists,
and such determination shall be binding on the

<PAGE>
 
Company only if approved in the form of a resolution by a majority of the Board,
or a majority of the disinterested trustees of the Board.  The Board will give
prompt notice of any such determination to the Company.

     7.2  The Company agrees that it will be responsible for reporting any
potential or existing conflicts to the Board.  The Company also agrees that, if
a material irreconcilable conflict arises, it will at its own cost remedy such
conflict up to and including: (a) withdrawing the assets allocable to some or
all of the Accounts from the Trust or any Fund and reinvesting such assets in a
different investment medium, including (but not limited to) another Fund of the
Trust, or submitting to a vote of all affected contract owners whether to
withdraw assets from the Trust or any Fund and reinvesting such assets in a
different investment medium and, as appropriate, segregating the assets
attributable to any appropriate group of contract owners that votes in favor of
such segregation, or offering to any of the affected contract owners the option
of segregating the assets attributable to their contracts or policies; and/or
(b) establishing and registering a new management investment company and
segregating the assets underlying the Contracts, unless a majority of Contract
owners materially adversely affected by the conflict have voted to decline the
offer to establish and register a new management investment company.

     7.3  A majority of the disinterested trustees of the Board shall determine
whether any proposed action by the Company adequately remedies any material
irreconcilable conflict.  In the event that the Board determines that any
proposed action does not adequately remedy any material irreconcilable conflict,
the Company will withdraw each Account designated by the disinterested trustees
from investment in the Trust and terminate this agreement within six (6) months
after the Board informs the Company in writing of the foregoing determination;
provided, that such withdrawal and termination shall be limited to the extent
required to remedy any such material irreconcilable conflict as determined by a
majority of the disinterested trustees of the Board.

     7.4  The Trust agrees that it will not enter into any participation
agreement with a life insurance company affiliated with the Company unless such
agreement includes a section substantially identical to this Article 7.


                                   ARTICLE 8
                                Indemnification

     8.1  Indemnification By The Company.
          ------------------------------ 

          (a)   The Company agrees to indemnify and hold harmless the Trust and
SFIM and each of the Trust's and SFIM's trustees, directors, and officers and
each person, if any, who controls the Trust or SFIM within the meaning of
Section 15 of the 1933 Act, and any agents or employees of the foregoing
(collectively, the "Indemnified Parties" for purposes of this Section 8.1),
against any and all losses, claims, damages, liabilities (including

<PAGE>
 
amounts paid in settlement with the written consent of the Company) or
litigation (including legal and other expenses), to which the Indemnified
Parties may become subject under any statute, regulation, at common law or
otherwise, insofar as such losses, claims, damages, liabilities or expenses (or
actions in respect thereof) or settlements are related to the sale or
acquisition of the Trust's shares or the Contracts and:

                (i)     arise out of or are based upon any untrue statements or
alleged untrue statements of any material fact contained in the registration
statement or prospectus for the Contracts or contained in the Contracts or sales
literature for the Contracts (or any amendment or supplement to any of the
foregoing), or arise out of or are based upon the omission or the alleged
omission to state therein a material fact required to be stated therein or
necessary to make the statements therein not misleading, provided, that this
agreement to indemnify shall not apply as to any Indemnified Party if such
statement or omission or such alleged statement or omission was made in reliance
upon and in conformity with information furnished the Company by or on behalf of
the Trust or SFIM for use in the registration statement or prospectus for the
Contracts or in the Contracts or sales literature (or any amendment or
supplement) or otherwise for use in connection with the sale of the Contracts or
Trust shares;

                (ii)    arise out of or as a result of statements or
representations (other than statements or representations contained in the
registration statement, prospectus or sales literature of the Trust not supplied
by the Company, or persons under its control) or wrongful conduct of the Company
or persons under its control, with respect to the sale or distribution of the
Contracts or Trust shares;

                (iii)   arise out of any untrue statement or alleged untrue
statement of a material fact contained in a registration statement, prospectus,
or sales literature of the Trust or any amendment thereof or supplement thereto
or the omission or alleged omission to state therein a material fact required to
be stated therein or necessary to make the statements therein not misleading if
such statement or omission was made in reliance upon information furnished to
the Trust or SFIM by or on behalf of the Company; or

                (iv)    arise out of or result from any material breach of any
representation and/or warranty made by the Company in this agreement or arise
out of or result from any other material breach of this agreement by the
Company; except to the extent provided in Sections 8.1(b) and 8.1(c) hereof.

          (b)   The Company shall not be liable under this indemnification
provision with respect to any claim made against an Indemnified Party unless
such Indemnified Party shall have notified the Company in writing within a
reasonable time after the summons or other first legal process giving
information of the nature of the claim shall have been served upon such
Indemnified Party (or after such Indemnified Party shall have received notice
of such service on any designated agent), but failure to notify the Company of

<PAGE>
 
any such claim shall not relieve the Company from any liability which it may
have to the Indemnified Party against whom such action is brought otherwise than
on account of this indemnification provision, except to the extent that failure
to notify results in failure of actual notice to the Company and the Company is
damaged solely as a result of failure to give notice. In case any such action is
brought against the Indemnified Parties, the Company shall be entitled to
participate, at its own expense, in the defense of such action.  The Company
also shall be entitled to assume the defense thereof, with counsel satisfactory
to the party named in the action.  After notice from the Company to such party
of the Company's election to assume the defense thereof, the Indemnified Party
shall bear the fees and expenses of any additional counsel retained by it, and
the Company will not be liable to such party under this agreement for any legal
or other expenses subsequently incurred by such party independently in
connection with the defense thereof other than reasonable costs of
investigation, unless:  (i) the Company and the Indemnified Party shall have
mutually agreed on the retention of such counsel; or (ii) the named parties to
any such proceeding (including any impleaded parties) include both the Company
and the Indemnified Party and representation of both parties by the same counsel
would be inappropriate due to actual or potential differing interests between
them.  The Company shall not be liable for any settlement of any proceeding
effected without its written consent but if settled with such consent or if
there be a final judgment for the plaintiff, the Company agrees to indemnify the
Indemnified Party from all and against any loss or liability by reason of such
settlement or judgment.

          (c)   The Indemnified Parties will promptly notify the Company of the
commencement of any litigation or proceedings against them in connection with
the issuance or sale of the Trust shares or the Contracts or the operation of
the Trust and the Indemnified Parties will provide the Company with all relevant
information and documents requested by the Company.  For purposes of this
Section 8.1(c), the "commencement" of proceedings shall include any informal or
formal communications from the SEC or its staff (or the receipt of information
from any other persons or entities) indicating that enforcement action by said
Commission or staff may be contemplated or forthcoming; this includes any
information to the effect that any matter(s) has been referred to the SEC's
Division of Enforcement, or that any matter(s) is being discussed with that
Division.

     8.2  Indemnification by the Trust and SFIM.
          ------------------------------------- 

          (a)   The Trust and SFIM, in each case solely to the extent relating
to such party's responsibilities hereunder, agree to indemnify and hold harmless
the Company and each of its directors and officers and each person, if any, who
controls the Company within the meaning of Section 15 of the 1933 Act, and any
agents or employees of the foregoing (collectively, the "Indemnified Parties"
for purposes of this Section 8.2), against any and all losses, claims, damages,
liabilities (including amounts paid in settlement with the written consent of
the Trust and SFIM) or litigation (including legal and other expenses) to which
the Indemnified Parties may become subject under any statute, at common law or
otherwise, insofar as such losses, claims, damages, liabilities or expenses (or
actions in respect

<PAGE>
 
thereof) or settlements are related to the sale or acquisition of the Trust's
shares or the Contracts and:

                 (i)   arise out of or are based upon any untrue statement or
alleged untrue statement of any material fact contained in the registration
statement or prospectus or sales literature of the Trust (or any amendment or
supplement to any of the foregoing), or arise out of or are based upon the
omission or the alleged omission to state therein a material fact required to be
stated therein or necessary to make the statements therein not misleading,
provided, that this agreement to indemnify shall not apply as to any Indemnified
Party if such statement or omission or such alleged statement or omission was
made in reliance upon and in conformity with information furnished to the Trust
by or on behalf of the Company for use in the registration statement or
prospectus for the Trust or in sales literature for the Trust (or any amendment
or supplement) or otherwise for use in connection with the sale of the Contracts
or Trust shares;

                 (ii)  arise out of or as a result of statements or
representations (other than statements or representations contained in the
registration statement, prospectus or sales literature for the Contracts not
supplied by the Trust, or persons under its control) or wrongful conduct of the
Trust or persons under its control, with respect to the sale or distribution of
the Contracts or Trust shares;

                 (iii) arise out of any untrue statement or alleged untrue
statement of a material fact contained in a registration statement, prospectus,
or sales literature covering the Contracts, or any amendment thereof or
supplement thereto, or the omission or alleged omission to state therein a
material fact required to be stated therein or necessary to make the statement
or statements therein not misleading, if such statement or omission was made in
reliance upon information furnished to the Company by or on behalf of the Trust;
or

                 (iv)  arise out of or result from any material breach of any
representation and/or warranty made by the Trust in this agreement or arise out
of or result from any other material breach of this agreement by the Trust
(including a failure, whether unintentional or in good faith or otherwise, to
comply with the requirements specified in Article 6 of this agreement);

except to the extent provided in Sections 8.2(b) and 8.2(c)  hereof.

           (b)   Neither the Trust nor SFIM shall be liable under this
indemnification provision with respect to any claim made against an Indemnified
Party unless such Indemnified Party shall have notified the Trust or SFIM in
writing within a reasonable time after the summons or other first legal process
giving information of the nature of the claim shall have been served upon such
Indemnified Party (or after such Indemnified Party shall have received notice of
such service on any designated agent), but failure to notify the Trust or SFIM
of any such claim shall not relieve the Trust or SFIM from any liability which
it may have to the Indemnified Party against whom such action is brought
otherwise than on account

<PAGE>
 
of this indemnification provision, except to the extent that failure to notify
results in the failure of actual notice to the Trust or SFIM and the Trust or
SFIM is damaged solely as a result of failure to give such notice.  In case any
such action is brought against the Indemnified Parties, the Trust and SFIM will
be entitled to participate, at their own expense, in the defense thereof. The
Trust and SFIM also shall be entitled to assume the defense thereof, with
counsel satisfactory to the party named in the action.  After notice from the
Trust or SFIM to such party of its election to assume the defense thereof, the
Indemnified Party shall bear the fees and expenses of any additional counsel
retained by it, and neither the Trust nor SFIM shall be liable to such party
under this agreement for any legal or other expenses subsequently incurred by
such party independently in connection with the defense thereof other than
reasonable costs of investigation, unless (i) the Trust, SFIM and the
Indemnified Party shall have mutually agreed to the retention of such counsel or
(ii) the named parties to any such proceeding (including any impleaded parties)
include the Trust or SFIM and the Indemnified Party and representation of both
parties by the same counsel would be inappropriate due to actual or potential
differing interests between them.  Neither the Trust nor SFIM shall be liable
for any settlement of any proceeding effected without their written consent but
if settled with such consent or if there be a final judgment for the plaintiff,
the Trust and SFIM agree to indemnify the Indemnified Party from and against any
loss or liability by reason of such settlement or judgment.

           (c)   The Indemnified Parties will promptly notify both the Trust and
SFIM of the commencement of any litigation or proceedings against them in
connection with the issuance or sale of the Trust shares or the Contracts or the
operation of the Trust and the Indemnified Parties will provide the Trust or
SFIM with all relevant information and documents requested by the Trust or SFIM,
respectively. For purposes of this Section 8.1(c), the "commencement" of
proceedings shall include any informal or formal communications from the SEC or
its staff (or the receipt of information from any other persons or entities)
indicating that enforcement action by said Commission or staff may be
contemplated or forthcoming; this includes any information to the effect that
any matter(s) has been referred to the SEC's Division of Enforcement, or that
any matter(s) is being discussed with that Division.

     8.3   A successor by law of the parties to this agreement shall be entitled
to the benefits of the indemnification contained in this Article 8.  The
indemnification provisions contained in this Article 8 shall survive any
termination of this agreement.

its obligations under this agreement; provided, that the Company shall not be
liable for any error of judgment or import of law, or for any loss suffered by
the Trust or SFIM in connection with the matters

<PAGE>
 
to which this agreement relates, except loss resulting from: (i) willful
misfeasance, bad faith or gross negligence on the part of the Company in the

reckless disregard of its obligations and duties under this agreement; or (iii)
a breach of Section 2.2 of this agreement.

           -------------------------------                                    
Company the benefit of SFIM's best judgment and efforts in fulfilling its
obligations under this agreement; provided, that SFIM shall not be liable for
any error of judgment or import of law, or for any loss suffered by the Trust or
the Company in connection with the matters to which this agreement relates,
except loss resulting from: (i) willful misfeasance, bad faith or gross
negligence on the part of SFIM in the performance of its obligations and duties
under this agreement; (ii) its reckless disregard of its obligations and duties
under this agreement; or (iii) a breach of Sections 2.4 or 6.1 of this
agreement.

     9.3   Limitation of Liability of Trust.  The Company and SFIM each

acknowledge that it has received notice of and accepts the limitations on the
Trust's liability as set forth in the Trust's Declaration of Trust, as amended
from time to time.  In accordance therewith, the Company and SFIM agree that the
Trust's obligations hereunder shall be limited to the assets of the Funds, and
with respect to each Fund shall be limited to the assets of such Fund, and no
party shall seek satisfaction of any such obligation from any shareholder of the
Trust, nor from any trustee, officer, employee or agent of the Trust.

written notice to the other party;

                 (ii)  at the option of the Company to the extent that shares of
the Funds are not reasonably available to meet the requirements of the Contracts
or are not "appropriate funding vehicles" for the Contracts, as determined by
the Company reasonably

<PAGE>
 
and in good faith; provided, that prompt notice of the election to terminate for
such cause and an explanation of such cause shall be furnished by the Company;

                 (iii) at the option of the Trust upon institution of formal
proceedings against the Company by the SEC or any insurance department or any
other regulatory body regarding the Company's duties under this agreement or
related to the sale of the Contracts, the operation of the Accounts, or the
purchase of the Trust shares;

                 (iv)  at the option of the Company upon institution of formal
proceedings against the Trust or SFIM by the NASD, the SEC, or any state
securities or insurance department or any other regulatory body;

                 (v)   at the option of the Company or the Trust upon receipt of
any necessary regulatory approvals and/or the vote of the Contract owners having
an interest in the Accounts (or any subaccount) to substitute the shares of
another investment company for the corresponding Fund shares of the Trust in
accordance with the terms of the Contracts for which those Fund shares had been
selected to serve as the underlying investment media; provided, that the Company
will give 30 days' prior written notice to the Trust of the date of any proposed
vote or other action taken to replace the Trust's shares; or

                 (vi)  at the option of the Company or the Trust, upon the other
party's material breach of any provision of this agreement.

           (b)   Without limiting the generality of Section 10.1(a)(ii), shares
of a Fund would not be "appropriate funding vehicles" if, for example, such
shares did not meet the diversification or other requirements referred to in
Article 6 hereof, the Fund did not qualify under Subchapter M of the Code, as
referred to in Section 2.4 hereof, the investments or investment policies,
objectives, and/or limitations of the Fund would impose unanticipated risks on
the Company, or if the Company would be permitted to disregard policy owner
voting instructions under the 1940 Act or the rules promulgated thereunder.

     10.3  Any notice pursuant to Section 10.1 shall specify the Fund or Funds,
Contracts and, if applicable, the Accounts as to which the agreement is to be
terminated.

     10.4  It is understood and agreed that the right of any party hereto to
terminate this agreement pursuant to Section 10.1(a) may be exercised for cause
or for no cause.

     10.5  Except as necessary to implement Contract owner initiated
transactions, or as required by state insurance laws or regulations, the Company
shall not redeem Trust shares attributable to the Contracts (as opposed to Trust
shares attributable to the Company's assets held in the Accounts), and the
Company shall not prevent Contract owners from allocating payments to a Fund
that was otherwise available under the Contracts, until thirty (30) days after
the Company shall have notified the Trust of its intention to do so.

<PAGE>
 
     10.6  Notwithstanding any termination of this agreement, the Trust shall,
at the option of the Company, continue to make available additional shares of
the Funds pursuant to the terms and conditions of this agreement for all
Contracts in effect on the effective date of termination of this agreement (the
"Existing Contracts").  Specifically, without limitation, the owners of the
Existing Contracts shall be permitted to transfer or reallocate investments
under the Contracts, redeem investments in the Trust and/or invest in the Trust
upon the making of additional purchase payments under the Existing Contracts.

               Registration Statement on Form N-1A
               (File No. 333-22467)
               --------------------------------------

Trustees:

          We have acted as counsel to State Farm Variable Product Trust (the
"Trust"), a business trust organized under the laws of the State of Delaware, in
connection with its registration as an open-end management investment company
under the Investment Company Act of 1940, as amended, and in connection with its
registration of an indefinite number of shares of beneficial interest in the
Trust (the "Shares") under the Securities Act of 1933, as amended (the "1933
Act"). In this connection, we have examined the initial registration statement
filed by you and pre-effective amendment number one to the registration
statement to be filed by you with the Securities and Exchange Commission on Form
N-1A (File No. 333-22467) (together, the "registration statement"). We also are
familiar with the actions taken by you at board of trustees meetings held on
June 13, 1997 and September 12, 1997, and intended to be taken by you, in
connection with the authorization, issuance and sale of the Shares.

          We have examined such Trust records, certificates and other documents
and reviewed such questions of law as we have considered necessary or
appropriate for purposes of this opinion.  In our examination of such materials,
we have assumed the genuineness of all signatures and the conformity to the
original documents of all copies submitted to us.  As to certain questions of
fact material to our opinion, we have relied upon statements of officers of the
Trust and upon representations of the Trust made in the registration statements.

          Based upon the foregoing, we are of the opinion that the Shares, when
issued and sold in the manner described in the registration statements, will be
legally issued, fully paid and non-assessable.

          We are attorneys licensed to practice only in the State of Georgia and
the District of Columbia.

statement of additional information filed as part of the registration
statements. 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 1933 Act. We also
hereby consent to the filing of this opinion as an exhibit to pre-effective
amendment number one to the registration statement to be filed by you with the
Securities and Exchange Commission on Form N-1A.

                              Very truly yours,
