 SUMMARY OF HOW OUR FUNDS INVEST


  Each Fund of Mutual of America Institutional Funds, Inc. (the INVESTMENT
  COMPANY) has its own investment objective and tries to achieve its objective
  with certain investment strategies. A Fund may not achieve its objective, or
  it may achieve its objective during some time periods but not during other
  time periods.

     The value of an investment in any of the Funds could decline, or it could
increase.

    o  As a very general rule, over longer investment periods the investment
       returns for stock funds tend to be higher than the returns for bond funds
       and money market funds.

    o  Stock funds have a higher risk for declines in value, especially over
       shorter investment periods, than bond funds and money market funds, and a
       stock fund's returns may vary significantly from year-to-year.

    o  Money market funds have the lowest risk for a decline in value, but they
       tend to have the lowest investment returns over longer investment
       periods.


  GENERAL RISKS OF INVESTING
    ----------------------------------------------------------------------------
   
  The Funds' different investment strategies will affect the return of the
  Funds and the risks of investing in each Fund. The Funds have certain
  general risks from investing, including:


  MARKET RISK, which refers to how much the value of a security changes
  (volatility of price) when conditions in the securities markets change or
  the economic environment changes.

    o  For debt securities, market risk includes changes in the overall level of
       interest rates. Interest rate increases usually cause a decline in the
       value of debt securities, while interest rate decreases usually cause an
       increase in the value of debt securities. Generally, the market risk for
       debt securities increases as the term to maturity (or expected redemption
       date) lengthens.

    o  Lower rated and unrated debt securities may be subject to a greater
       market risk than higher rated (investment grade) debt securities, and
       zero coupon securities or discount notes may be subject to a greater
       market risk than securities that pay interest on a regular basis.

    o  For equity securities, market risk may vary with a security's
       characteristics. Stocks of companies with smaller market capitalizations
       generally have more market risk than stocks of companies with larger
       market capitalizations. Blue chip, growth or value securities may have
       different market risks at a given time, depending on the type of
       security(ies) that are then in favor with investors.

    o  Equity securities that trade over-the-counter may be more difficult to
       sell and may be subject to more market risk in declining markets than
       equity securities that trade on a national securities exchange.


  FINANCIAL (OR CREDIT) RISK, which refers to the ability to pay principal and
  interest by an issuer of a debt security and to the earning stability and
  overall financial soundness of an issuer of an equity security.

    o  Debt securities issued by the U.S. Government or its agencies are
       considered to have no or very little financial risk, and debt securities
       with higher ratings are considered to have less financial risk than
       lower-rated debt securities.


  CURRENT INCOME VOLATILITY, which refers to how much and how quickly changes in
  the overall level of interest rates become reflected in the level of a fund's
  current income.

    o  Income volatility applies primarily to debt securities. When a fund holds
       a security that matures or prepays, the fund will invest the proceeds at
       current interest rates. For this reason, a fund's income volatility
       increases as the average maturity of its portfolio holdings shortens.
                                      -2-

  STOCK FUNDS
    ----------------------------------------------------------------------------
   
  An investment in the Equity Index Fund or All America Fund is subject to
  market risk and financial risk. Approximately 20% of the All America Fund's
  assets are invested in small capitalization growth and value stocks, and
  this portion of its portfolio will have more market and financial risk than
  the portion invested in mid and large capitalization stocks.

  EQUITY INDEX FUND: The Fund seeks investment results that are the same as
  the performance of the Standard & Poor's Composite Index of 500 Stocks (the
  S&P 500(R) INDEX*). The Fund invests in the 500 common stocks included in
  the S&P 500 Index and in futures contracts on the S&P 500 Index.

    o  Securities in the S&P 500 Index generally are issued by companies with
       large and mid-sized market capitalizations.

    o  Securities are included in the Index based on industry weightings and the
       issuers' leading positions in those industries.

  ALL AMERICA FUND: The Fund attempts to outperform the S&P 500 Index*, by
  investing primarily in common
  stocks.

    o  Approximately 60% of the Fund's assets are invested to replicate the S&P
       500 Index. This portion of the Fund purchases the 500 common stocks
       included in the S&P 500 Index and futures contracts on the S&P 500 Index.

    o  Approximately 40% of the Fund's assets are invested by the Adviser and
       three Subadvisers, each having approximately 10% of the Fund's assets,
       with an objective of capital appreciation and, to a lesser extent,
       current income. The Adviser invests primarily in small capitalization
       value stocks. One Subadviser invests primarily in small capitalization
       growth stocks. Another Subadviser invests primarily in mid- and large
       capitalization growth stocks. The third Subadviser invests primarily in
       large capitalization value stocks.


  BOND FUND
    ----------------------------------------------------------------------------
     
     The Fund seeks current income, by investing primarily in publicly-traded,
investment grade debt securities.


    o  The Fund invests in corporate, U.S. Government securities and U.S.
       Government agency securities, such as bonds, notes, debentures, zero
       coupon securities and mortgage-backed securities.

    o  Depending on market conditions, the Fund may have a significant portion
       of its assets invested in a particular type of debt security, such as
       U.S. Government agency mortgage-backed securities or zero coupon
       securities.

    o  The Adviser generally selects securities based on interest income to be
       generated and generally does not time purchases and sales based on
       interest rate predictions.

  Because the Fund purchases primarily investment grade debt securities,
  including securities issued by the U.S. Government and its agencies, it
  should have a moderate amount of financial risk. If the Fund holds a
  significant percentage of mortgage-backed securities or zero coupon
  securities, the market risk for an investment in the Fund may increase.

  An investment in the Bond Fund is subject to market risk, with the amount of
  market risk increasing as the average maturity of the Fund's portfolio
  lengthens. The Fund also has current income volatility risk, with the risk
  decreasing as the average maturity of the Fund's portfolio lengthens.

     ----------
 * Standard & Poor's Corporation (S&P) does not sponsor, endorse, sell or
   promote the Equity Index Fund or All America Fund. S&P has licensed to the
   Investment Company certain trademarks and trade names of S&P and the S&P
   500 Index. S&P has no obligation or liability for the sale or operation of
   the Equity Index Fund and All America Fund.


                                      -3-
<PAGE>

  MONEY MARKET FUND
    ----------------------------------------------------------------------------
     
  The Fund seeks current income and preservation of principal by investing in
  money market instruments that meet certain requirements for liquidity,
  investment quality and stability of capital.

    o  The dollar-weighted average maturity of the instruments the Fund holds
       will be 90 days or less.

    o  The Fund will purchase only securities that are rated in one of the two
       highest categories by two rating agencies, and most of the securities
       will be rated in the highest category by two rating agencies.

  The Money Market Fund does not operate in a way to maintain a stable net
  asset value of $1.00, because it pays dividends of income earned on a
  semi-annual basis. The Fund's net asset value will generally rise during the
  year as the Fund earns income and will decline when dividends are declared
  and income is paid to shareholders.

  A shareholder's investment in the Fund is not insured or guaranteed by the
  Federal Deposit Insurance Corporation or any other government agency.

  An investment in the Money Market Fund has a small amount of market risk and
  financial risk, because the Fund holds high quality securities with short
  terms to maturity. The Fund has a high level of current income volatility,
  because its securities holdings are short term and it reinvests as its
  holdings mature.

  ANNUAL TOTAL RETURNS
    ----------------------------------------------------------------------------
   
  The bar charts below show the annual return of each Fund for the life of the
  Fund, except that the Equity Index Fund is not included because it began
  operations on May 1, 1999. A chart indicates the risks of investing in a
  particular Fund by showing changes in the Fund's performance from
  year-to-year during the period, but a Fund's past performance does not
  necessarily indicate how it will perform in the future.

  Next to each chart is the Fund's highest total return for any calendar
  quarter during the period covered by the chart, called the BEST QUARTER
  RETURN, and the Fund's lowest total return for any calendar quarter during
  the period covered, called the WORST QUARTER RETURN. These returns are an
  indication of the volatility of a Fund's total returns.

  AVERAGE ANNUAL TOTAL RETURNS (FOR PERIODS ENDED DECEMBER 31, 1998)
    ----------------------------------------------------------------------------
   
  The table below shows the average annual total returns of each Fund for the
  past one year period and the return for the period of the Fund's operations,
  except that the Equity Index Fund is not included because it began
  operations on May 1, 1999. The table indicates the risks of investing in the
  Funds by comparing, for the same periods, each Fund's returns to those of a
  broad-based, unmanaged index, or to Treasury Bills for money market
  investments. A Fund's past performance does not necessarily indicate how it
  will perform in the future.

* The 1999 Other Expenses and Total Operating Expenses of the Equity Index Fund,
  which began operations on May 1, 1999, have been estimated by the Adviser.

**The Adviser has contractually agreed for 1999 to limit each Fund's total
  expenses (excluding taxes, brokerage commissions and extraordinary expenses)
  to an annual rate of .325% of the net assets of the Equity Index Fund, .85% of
  net assets for the All America Fund, .70% of net assets for the Bond Fund and
  .40% of net assets for the Money Market Fund. The Adviser's obligation will
  continue for each following calendar year unless the Adviser gives notice of
  termination to the Investment Company at least two weeks before the next year
  begins.

  EXAMPLE:

  This Example is intended to help you compare the cost of investing in the
  Funds with the cost of investing in other mutual funds. The Example assumes
  for each Fund that:

     o  you make an investment of $10,000,

     o  you have a 5% annual return on your investment,

     o  Fund operating expenses stay the same during the periods shown, and

     o  you redeem all of your shares at the end of the periods shown.

     Although your costs may be higher or lower, your cost based on these
assumptions would be:

  The expenses used in the Example are those shown in the table above and
  reflect the Adviser's contractual obligation to pay the Funds' expenses.
  Because the Equity Index Fund is a new fund, the Example covers only a 1
  Year and 3 Year period for the Fund.


  COMPARISON WITH AVERAGE ANNUAL TOTAL RETURNS OF SIMILAR FUNDS
    ----------------------------------------------------------------------------
   
  The investment policies, objectives and strategies of the Investment
  Company's Equity Index Fund, All America Fund, Bond Fund and Money Market
  Fund are substantially identical to those of Mutual of America Investment
  Corporation's Equity Index Fund, All America Fund, Bond Fund and Money
  Market Fund (called the VP or VARIABLE PRODUCTS Funds). In addition, the
  Adviser and Subadvisers for these Variable Products Funds are the same as
  for the corresponding Investment Company Fund, and the portfolio managers
  are the same.

  Shares of the Mutual of America Investment Corporation's funds are sold only
  to separate accounts of Mutual of America Life Insurance Company and its
  indirect wholly owned subsidiary, The American Life Insurance Company of New
  York, as a funding medium for variable accumulation annuity contracts and
  variable life insurance policies issued by these companies.

  Below are average annual total returns for the VP Funds, based on
  information about the VP Funds that the Adviser has provided, compared to
  returns for the Investment Company's Funds for the periods indicated, other
  than for the Equity Index Fund which began operations on May 1, 1999. Past
  performance of the Variable Products Funds is not predictive of future
  performance. Investors should not consider performance data for the VP Funds
  as an indication of the future performance of the Equity Index, All America,
  Bond and Money Market Funds offered under this Prospectus.

        Fund, Bond Fund and Money Market Fund of the Investment Company were
        .82%, .70% and .40%, respectively, of average net assets.

    o   The VP All America Fund, from May 1994 until June 1995, had a Subadviser
        for approximately 10% of the Fund's assets currently managed by the
        Adviser.

    o   At year end 1998, VP Equity Index Fund had net assets of $411 million,
        VP All America Fund had net assets of $732 million, VP Bond Fund had net
        assets of $465 million, and VP Money Market Fund had net assets of $81

  the Money Market Fund because of the type of investments it makes. No
  information is given for the Equity Index Fund or the Indexed Assets of the
  All America Fund, because the investment objective for each is to replicate
  the performance of an index.


     ALL AMERICA FUND


  THOMAS P. LARSEN, Executive Vice President of the Adviser, is responsible
  for managing the Adviser's portion of the actively managed assets of the
  Fund. Mr. Larsen joined the Adviser in June 1998, after serving as Senior

  YEAR 2000 CONSIDERATIONS
    ----------------------------------------------------------------------------
   
  Many computers cannot distinguish the year 2000 from the year 1900, and this
  inability could adversely impact the handling of securities trades, the
  payment of interest and dividends, pricing, accounting and other
  recordkeeping services by the Adviser or the outside service providers for
  the Investment Company and the Adviser.

  The Adviser has reviewed its computer systems and has made modifications and
  replacements to prepare for the year 2000. It has begun testing the modified
  systems and will continue testing throughout 1999. The Adviser has received
  confirmation from the Adviser's and the Investment Company's outside service
  providers that they expect to modify or replace their systems to prepare for
  the year 2000. The Investment Company anticipates that the Adviser's
  computer systems and those of the outside providers will be adapted in time
  for the year 2000. It is possible that the Investment Company, or its
  outside service providers, could experience some computer processing
  problems when the year 2000 arrives. We are developing written contingency
  plans to ensure business continuity through the year 2000.

 DETAILS ABOUT HOW OUR FUNDS INVEST AND RELATED RISKS


  INVESTMENT OBJECTIVES AND STRATEGIES
    ----------------------------------------------------------------------------
                  
  EQUITY INDEX FUND: The investment objective of the Equity Index Fund is to
                 provide investment results that to the extent practicable
                 correspond to the price and yield performance of publicly
                 traded common stocks in the aggregate, as represented by the
                 S&P 500 Index.

  The Fund seeks to achieve its objective primarily by:

    o   Purchasing shares of the 500 common stocks that are included in the S&P
        500 Index.


        - Stocks are selected in the order of their weightings in the S&P 500
          Index, beginning with the heaviest weighted stocks.

        - The percentage of the Fund's assets invested in each of the selected
          stocks will be approximately the same as the percentage the stock
          represents in the S&P 500 Index.

        - The Fund attempts to be fully invested at all times, and at least 80%
          of the Fund's net assets will be invested in the stocks that comprise
          the S&P 500 Index.

    o   Purchasing futures contracts on the S&P 500 Index and options on futures
        contracts on the S&P 500 Index to invest cash prior to the purchase of
        common stocks, in an attempt to have the Fund's performance more closely
        correlate with the performance of the S&P 500 Index.

  The Adviser uses a computer program to determine which stocks are to be
  purchased or sold to copy the S&P 500 Index. From time to time, the Fund
  makes adjustments in its portfolio (rebalances) because of changes in the
  composition of the S&P 500 Index or in the valuations of the stocks within
  the Index relative to other stocks within the Index.

  The Fund's investment performance may not precisely duplicate the
  performance of the S&P 500 Index, due to cash flows in and out of the Fund
  and investment timing considerations. The Fund also pays investment advisory
  expenses that are not applicable to an unmanaged index such as the S&P 500
  Index.

  The Fund's ability to duplicate the performance of the S&P 500 Index depends
  to some extent on the size of the Fund's portfolio. Mutual of America Life
  Insurance Company (MUTUAL OF AMERICA) the indirect parent corporation of the
  Adviser, and an affiliate invested a total of $25 million in the Equity
  Index Fund when the Fund began operations. Mutual of America (directly or
  through an affiliate) currently intends to maintain an investment in the
  Fund so that the Fund's assets are at least $25 million at any time.


  ALL AMERICA FUND: The investment objective of the All America
                    Fund is to outperform the S&P 500 Index by providing a
                    diversified portfolio of Active Assets with diversified
                    management and a broad exposure to the market.

  At least 65% of the All America Fund's total assets will be invested in
  equity securities under normal market conditions. The issuers of at least
  80% of the Fund's total assets will be United States corporations or
  entities.

  INDEXED ASSETS. The investment objective for approximately 60% of the assets
  of the All America Fund is to provide investment results that to the extent
  practicable correspond to the price and yield performance of publicly traded
  common stocks in the aggregate, as represented by the S&P 500 Index. The
  Fund invests Indexed Assets in the 500 common stocks included in the S&P 500
  Index and in futures contracts on the S&P 500 Index. The Fund attempts to
  match the weightings of stocks in the Indexed Assets with the weightings of
  those stocks in the S&P 500 Index.

  The Indexed Assets are invested in the same manner as the Equity Index Fund,
  discussed above. The Fund's ability to duplicate the performance of the S&P
  500 Index depends to some extent on the size of the Fund's portfolio. Mutual
  of America invested $50 million in the All America Fund when the Fund began
  operations. Mutual of America (directly or through an affiliate) currently
  intends to maintain an investment in the Fund so that the Fund's assets are
  at least $25 million at any time.

  ACTIVE ASSETS. The investment objective for the remaining approximately 40%
  of the assets of the Fund is to achieve a high level of total return,
  through both appreciation of capital and, to a lesser extent, current
  income, by means of a diversified portfolio of primarily common stocks.


                                      -11-

  The Fund tries to maintain, to the extent possible, approximately equal
  amounts with the Adviser and the three Subadvisers. The Adviser periodically
  rebalances assets in the All America Fund to retain the approximate 60%/40%
  relationship between Indexed Assets and Active Assets.

  Adviser. The Adviser generally invests in stocks that it considers
  undervalued and with the potential for above average investment returns,
  issued by companies with small market capitalizations (small cap value
  stocks). Some of the companies whose stocks the Adviser selects may have
  limited Wall Street coverage and low institutional ownership, which may make
  the stocks more difficult to sell in certain market conditions.

    o   The Adviser seeks securities with a depressed valuation compared to
        their previous valuations or compared to a universe of peer companies.
        The Adviser determines depressed valuation primarily through
        consideration of earnings, cash flow or net equity.

    o   Issuers must have executive management that the Adviser considers strong
        and capable of executing a clear business strategy for the company.


  Fred Alger Management, Inc. This Subadviser invests in stocks that it
  considers to be fundamentally sound with the potential for strong growth and
  for earnings in excess of market expectations, issued by companies with
  small market capitalizations (small cap growth stocks).

    o   The securities of these companies often are traded in the
        over-the-counter market.

    o   Except during temporary defensive periods, at least 65% of the assets in
        the Fred Alger portfolio will be invested in equity securities of
        companies that, at the time of the Fund's purchase, have total market
        capitalization within the range of capitalization of the companies
        included in the Russell 2000 Growth Index or the S&P SmallCap 600 Index,
        updated quarterly.

  Fred Alger Management, Inc. actively trades the securities in its portion of
  the All America Fund, and its portfolio
  turnover rate generally will be higher than the portfolio turnover rate for
  the other Subadvisers.


  Oak Associates, Ltd. This Subadviser invests in mid- and large-sized
  capitalization stocks, which often have low current income and the potential
  for significant growth (mid- and large capitalization growth stocks). Its
  approach is to:

    o   monitor 400 stocks,

    o   at any one time to invest in approximately 15-25 common stocks without
        regard for market industry weighting, and

    o   usually hold securities that have appreciated in value, rather than
        selling them to realize capital gains.

  Palley-Needelman Asset Management, Inc. This Subadviser invests its portion
  of Active Assets in stocks it considers to be of high quality with lower
  than average price volatility and low price/earning ratios, issued by
  companies with large market capitalizations (large cap value stocks).
  Companies generally will have:

    o   below market debt levels,

    o   earnings growth of 10% or more,

    o   current yield greater than the average of the S&P 500, and

    o   market capitalization of at least $5 billion.


  BOND FUND: The primary investment objective of the Bond Fund is to
             provide as high a level of current income over time as is believed
             to be consistent with prudent investment risk. A secondary
             objective is preservation of shareholders' capital.

  The average maturity of the debt securities held by the Bond Fund will vary
  according to market conditions and the stage of the interest rate cycle.

  The Fund invests at least 80% of its assets in investment grade debt
  obligations issued by U.S. corporations or issued by the U.S. Government or
  its agencies.


                                      -12-
<PAGE>

    o   The Fund may invest in various types of debt securities, including
        bonds, mortgage-backed securities, zero coupon securities and
        asset-backed securities,with ratings that range from AAA to BBB.

    o   The percentage of the Fund's portfolio invested in particular types of
        securities will vary, depending on market conditions and the Adviser's
        assessment of the income and returns available from corporate securities
        in relation to the risks of investing in these securities.

    o   At December 31, 1998, the Bond Fund had approximately 4% of its assets
        invested in zero coupon securities, 24% of its assets in U.S. Treasury
        Securities, 11% of its assets in U.S. Government agency mortgage-backed
        securities and 26% of its assets in corporate obligations rated BBB.

  The Adviser uses a "bottom-up" approach in selecting debt securities for the
  Fund. This means that the Adviser evaluates each issuer of securities before
  making an investment, rather than selecting securities or industries based
  on possible changes in the economy.

  The Adviser's approach generally is to purchase securities for income,
  instead of purchasing and selling securities in anticipation of interest
  rate changes in the economy. The Adviser may sell a security that it
  considers to have become overvalued relative to alternative investments, and
  reinvest in an alternative security.


  MONEY MARKET FUND: The investment objective of the Fund is to realize high
                     current income to the extent consistent with the          
                     maintenance of liquidity, investment quality and stability
                     of capital.

    o   The Fund invests only in high quality money market instruments and other
        short-term debt securities, including commercial paper issued by U.S.
        corporations and in U.S. Government and U.S. Government agency
        securities. At December 31, 1998, more than 80% of the Fund's assets
        were invested in commercial paper, with the remainder invested in U.S.
        Government agency securities.

    o   All of the securities the Fund purchases have a rating in one of the two
        highest rating categories from at least two nationally recognized rating
        agencies, and substantially all (at least 95%) have a rating in the
        highest category from at least two of these rating agencies.

    o   At the time of purchase, a security must mature in 13 months or less (or
        25 months for U.S. Government securities). The dollar-weighted average
        maturity of the Fund's securities must be 90 days or less.

  The Fund does not maintain a stable net asset value. Income the Fund earns
  on its portfolio holdings increases the Fund's net asset value per share
  until the Fund declares a dividend. The Fund declares a dividend of net
  investment income at least semi-annually, and the Fund's net asset value per
  share declines as a result of the distribution to its shareholders.

  The Fund uses the amortized cost method of valuing securities that have a
  remaining term to maturity of 60 days or less. Because the Fund uses market
  value for securities that mature in more than 60 days, the Fund does not
  invest more than 20% of its assets in these securities, to limit the
  possibility of a decline in the Fund's net asset value.

  An investment in the Fund has little market or financial risk but a
  relatively high level of current income volatility, because its portfolio
  holdings are high quality instruments that have a short time to maturity.
  INVESTMENTS IN THE MONEY MARKET FUND ARE NOT INSURED OR GUARANTEED BY THE
  U.S. GOVERNMENT OR ANY OF ITS AGENCIES


  RISKS OF INVESTING IN A STOCK FUND
    ----------------------------------------------------------------------------
   
     When you invest in a stock fund, you should consider that:


    o   The fund is subject to market risk -- the value of your investment will
        go up or down, depending on movements in the stock markets. As a result,
        you may lose money from your investment, or your investment may increase
        in value.

    o   The investment results for a particular Fund may be better or worse than
        the results for the stock markets taken as a whole, depending on the
        type of securities in which the Fund invests.


                                      -13-
<PAGE>

    o   The investment results for a particular Fund may be better or worse than
        the results of other funds that invest in the same types of securities.
        In other words, stock selection by a Fund's investment adviser(s) will
        impact the Fund's performance.

    o   The prices and investment performance of stocks that are issued by
        companies with smaller market capitalizations may fluctuate more than
        the prices and investment performance of stocks that are issued by
        companies with larger market capitalizations.

    o   A Fund may have more difficulty selling a small cap stock or any stock
        that trades "over-the-counter", as compared to larger capitalization
        stocks or stocks that trade on a national or regional stock exchange.

    o   Value stocks and growth stocks usually have different investment
        results, and either investment style may become out of favor with stock
        investors at a given time.


  RISKS OF INVESTING IN A BOND FUND
    ----------------------------------------------------------------------------
     
     When you invest in a bond fund, you should consider that:


    o   The fund has market risk -- the value of your investment will go up or
        down depending on movements in the bond markets. As a result, you may
        lose money from your investment, or your investment may increase in
        value.

    o   The investment results for a particular Fund may be better or worse than
        the results for the comparable bond market taken as a whole, depending
        on the type of debt securities in which the Fund invests.

    o   The investment results for a particular Fund may be better or worse than
        the results of other funds that invest in the same types of securities.
        In other words, security selection by a Fund's investment adviser will
        impact the Fund's performance.

    o   Changes in prevailing interest rates usually will impact the value of
        debt securities. The longer the time period before the security matures
        (or is expected to be redeemed), the more impact interest rate changes
        will have on the price of the bond. When interest rates rise, the prices
        of outstanding debt securities tend to fall. When interest rates fall,
        the prices of outstanding debt securities tend to rise.

    o   Mortgage-backed securities or certificates are subject to prepayment or
        extension risk when interest rates change. When interest rates fall, the
        underlying mortgages may be prepaid at a faster rate than previously
        assumed in pricing the mortgage-backed security, which would shorten the
        period to maturity. When interest rates rise, the underlying mortgages
        may be prepaid at a slower rate than previously assumed, which would
        lengthen the period to maturity.

    o   In periods of economic uncertainty, investors may favor U.S. government
        debt securities over debt securities of corporate issuers, in which case
        the value of corporate debt securities would decline in relation to the
        value of U.S. government debt securities.

    o   Zero coupon securities and discount notes do not pay interest, and they
        may fluctuate more in market value and be more difficult for a Fund to
        resell during periods of interest rate changes than comparable
        securities that pay interest in cash at regular intervals. In addition,
        the Fund may lose a portion of the principal amount of a zero coupon
        security if it sells the security after an increase in interest rates.

    o   Unrated securities or securities rated below investment grade may be
        subject to a greater market risk than higher rated (lower yield)
        securities. Since lower rated and unrated securities are generally
        issued by corporations that are not as creditworthy or financially
        secure as issuers of higher rated securities, there is a greater risk
        that issuers of lower rated (higher yield) securities will not be able
        to pay the principal and interest due on such securities, especially
        during periods of adverse economic conditions.

    o   The market for debt securities may be subject to significant volatility,
        and volatility has generally increased in recent years.

  SPECIFIC INVESTMENTS OR STRATEGIES, AND RELATED RISKS
    ----------------------------------------------------------------------------
   
  This section provides additional information about certain of the principal
  investment strategies used by the Funds and additional investment strategies
  the Funds may use from time to time.


     OPTIONS AND FUTURES CONTRACTS

  All of the Funds may purchase and sell put and call options contracts,
  futures contracts and options on futures contracts. Depending on the types
  of securities in which a Fund invests, the contracts relate to fixed-income
  securities (including U.S. Government and agency securities), equity
  securities or indexes of securities. All contracts must be traded on
  securities or commodities exchanges located in the United States.

  A put option on a security gives the Fund the right to sell the security at
  a certain price. The purchase of a put option on a security protects the
  Fund against declines in the value of the security.

  A call option on a security gives the Fund the right to buy the security at
  a certain price. The purchase of a call option on a security protects the
  Fund against increases in the value of the security that it is considering
  purchasing.

  A Fund may use futures contracts, or options on futures contracts, to
  protect against general increases or decreases in the levels of securities
  prices:

    o   When a Fund anticipates a general decrease in the market value of
        portfolio securities, it may sell futures contracts. If the market value
        falls, the decline in the Fund's net asset value may be offset, in whole
        or in part, by corresponding gains on the futures position.

    o   When a Fund projects an increase in the cost of fixed-income securities
        or stocks to be acquired in the future, the Fund may purchase futures
        contracts on fixed-income securities or stock indexes. If the hedging
        transaction is successful, the increased cost of securities subsequently
        acquired may be offset, in whole or in part, by gains on the futures
        position.

     Risks to a Fund in options and futures transactions include the following:
 

    o   There may be a lack of liquidity, which could make it difficult for a
        Fund to close out existing positions.

    o   The securities held in a Fund's portfolios may not exactly duplicate the
        security or securities underlying the options, futures contracts or
        options on futures contracts traded by the Fund, and as a result the
        price of the portfolio securities being hedged will not move in the same
        amount or direction as the underlying index, securities or debt
        obligation.

    o   A Fund purchasing an option may lose the entire amount of the premium
        plus related transaction costs.

    o   If a Fund has written a covered call option and the price of the
        security underlying the option moves adversely to the Fund's position,
        the option may be exercised. The Fund will be required to sell the
        security at a disadvantageous price, and the resulting loss may be
        offset only by the amount of the premium the Fund received from writing
        the option.


     ZERO COUPON SECURITIES AND DISCOUNT NOTES

  The Bond Funds, as well as the All America Fund to the extent it invests in
  fixed income securities, may invest in discount notes and zero coupon
  securities. Discount notes mature in one year or less from the date of
  issuance. Zero coupon securities may be issued by corporations, the U.S.
  Government or certain U.S. Government agencies. Discount notes and zero
  coupon securities do not pay interest. Instead, they are issued at prices
  that are discounted from the principal (par) amount due at maturity.

  Zero coupon securities and discount notes may fluctuate more in market value
  and be more difficult for a Fund to resell during periods of interest rate
  changes in the economy than comparable securities that pay interest in cash
  at regular intervals. The market values of outstanding debt securities
  generally decline when interest rates are rising, and during such periods a
  Fund may lose more investment capital if it sells zero coupon securities
  prior to their maturity date or expected redemption date than if it sells
  comparable interest-bearing securities. In general, the longer the remaining
  term to maturity or expected redemption of a security, the greater the
  impact on market value from rising interest rates.


                                      -15-
<PAGE>

  REDEEMABLE SECURITIES

  An issuer of debt securities, including zero coupon securities, often has
  the right after a period of time to redeem (call) securities prior to their
  stated maturity date, either at a specific date or from time to time. When
  interest rates rise, an issuer of debt securities generally is less likely
  to redeem securities that were issued at a lower interest rate, or for a
  lower amount of original issue discount in the case of the zero coupon
  securities. In such instance, the period until redemption or maturity of the
  security may be longer than the purchaser initially anticipated, and the
  market value of the debt security may decline. If an issuer redeems a
  security when prevailing interest rates are relatively low, a Fund may be
  unable to reinvest proceeds in comparable securities with similar yields.


     AMERICAN DEPOSITORY RECEIPTS ("ADRS")

  ADRs are dollar-denominated receipts that U.S. banks generally issue. An ADR
  represents the deposit with the bank of a security of a foreign issuer. ADRs
  are publicly traded on exchanges or are traded over-the-counter in the
  United States. An ADR has currency risk, because its value is based on the
  value of the security issued by a foreign issuer. The All America Fund
  intends to invest a small percentage of its total assets in ADRs.

     ADRs are subject to many of the same risks as foreign securities, such as
  possible:

    o   unavailablity of financial information,

    o   changes in currency or exchange rates,

    o   lack of Year 2000 preparedness by the issuer, and

    o   difficulty by the Adviser or a Subadviser in assessing economic or
        political trends in a foreign country.


     MORTGAGE-BACKED SECURITIES

  The Bond Fund, as well as the All America Fund to the extent it invests in
  debt securities, may invest in mortgage-backed securities. These securities
  represent interests in pools of mortgage loans, or they may be
  collateralized mortgage obligations secured by pools of mortgage loans
  ("CMOs"). Holders of mortgage-backed securities receive periodic payments
  that consist of both interest and principal from the underlying mortgages.

  Some mortgage-backed securities are issued by private corporations.
  Mortgage-backed securities also include securities guaranteed by the
  Government National Mortgage Association ("Ginnie Maes"), securities issued
  by the Federal National Mortgage Association ("Fannie Maes"), participation
  certificates issued by the Federal Home Loan Mortgage Corporation ("Freddie
  Macs"). The timely payment of principal and interest is backed by the full
  faith and credit of the U.S. Government in the case of Ginnie Maes, but
  Fannie Maes and Freddie Macs are not full faith and credit obligations.

  Characteristics of underlying mortgage pools will vary, and it is not
  possible to precisely predict the realized yield or average life of a
  particular mortgage-backed security, because of the principal prepayment
  feature inherent in the security.

    o   A decline in interest rates may lead to increased prepayment of the
        underlying mortgages, and the securityholder may have to reinvest
        proceeds received at lower yields. Unscheduled or early payments on the
        underlying mortgages may shorten the effective maturity of a
        mortgage-backed security and could negatively affect the yield and price
        of the security.

    o   An increase in interest rates may lead to prepayment of the underlying
        mortgages at a lower rate than was assumed when the mortgage-backed
        security was purchased, and the securityholder may not receive payments
        to reinvest at higher rates of return. Delay in payments on the
        underlying mortgages may lengthen the effective maturity of the security
        and could negatively affect the price and yield of the security.

 INFORMATION ABOUT FUND SHARES


  PRICING OF FUNDS' SHARES
    ----------------------------------------------------------------------------
   
  The purchase or redemption price of a Fund share is equal to its net asset
  value that we next calculate after we receive the purchase or redemption
  order. The Adviser determines a Fund's net asset value as of the close of
  trading on the New York Stock Exchange on each day the New York Stock
  Exchange is open for trading (a VALUATION DAY). The Exchange usually closes
  at 4:00 p.m. Eastern Time but sometimes closes earlier before a holiday.

    o   In determining a Fund's net asset value, the Adviser uses market value.
         

    o   If a money market security has a remaining maturity of 60 days or less,
        the Adviser will use the amortized cost method of valuation to
        approximate market value (the Adviser assumes constant proportionate
        amortization in value until maturity of any discount or premium).

    o   If there are any equity or debt securities or assets for which market
        quotations are not readily available, the Adviser will use fair value
        pricing, as determined in good faith by, or under the direction of, the
        Board of Directors of the Investment Company.

  PURCHASES OF FUND SHARES
    ----------------------------------------------------------------------------
   
  Only institutional investors may purchase Fund shares. Institutional
  investors include endowments, foundations, corporations, not-for-profit
  corporations, municipalities and other public entities and trusts. There is
  no sales charge for the purchase of Fund shares.

  Mutual of America Securities Corporation, 320 Park Avenue, New York, New
  York 10022 (the DISTRIBUTOR), is the principal underwriter and distributor
  of Fund shares. The Distributor has field offices throughout the United
  States for the offering and sale of shares of the Investment Company's
  Funds.

  A shareholder must pay the purchase amount by wire transfer of Federal
  Funds. Wire transfers can be made on any day on which the Investment
  Company, Federal Reserve Bank of New York and the Investment Company's
  custodian and transfer agent are open and the New York Stock Exchange is
  open.

  The Investment Company reserves the right to reject any purchase order, to
  increase or decrease the minimum required initial and subsequent investments
  and to waive the minimum for an initial investment or for subsequent
  investments.

  RECEIPT OF ORDER:
                           Wire transfer funds received by the Investment
                           Company in its account prior to 4:00 p.m. Eastern
                           Time will be considered received that day. Purchase
                           amounts received after 4:00 p.m. Eastern Time will
                           be considered received on the next Valuation Day.

  WIRE TRANSFER DAYS:      Wire transfers for the purchase of Fund shares can
                           be made on days when banks (including the transfer
                           agent) and the New York Stock Exchange are open for
                           business. The Investment Company anticipates that
                           wire transfers cannot be made on Saturdays and
                           Sundays, and the holidays of Martin Luther King,
                           Jr.'s Birthday, Presidents' Day, Good Friday,
                           Memorial Day, Independence Day, Labor Day, Columbus
                           Day, Veterans' Day, Thanksgiving Day, Christmas Day

  REDEMPTIONS OF FUND SHARES
    ----------------------------------------------------------------------------
   
  A shareholder at any time may redeem (sell) shares of the Fund(s) that the
  shareholder owns. There is no deferred sales charge when a shareholder
  redeems shares of the Funds.

  If a shareholder's redemption order is received by 4:00 p.m. Eastern Time on
  a Valuation Day, the redemption proceeds usually will be transmitted on a
  trade date-plus-one basis (the next Valuation Day). Wire transfers of


                                      -18-
<PAGE>

  redemption proceeds cannot be made on days the transfer agent is closed. See
  "Wire transfer days" above under "How to Purchase Shares of the Funds".

  We pay redemption proceeds normally within seven days of receipt of the
  redemption request, unless the Investment Company suspends or delays payment
  of redemption proceeds as permitted in accordance with SEC regulations.

  A shareholder will receive redemption proceeds in cash deposited to its bank
  account, except that the Investment Company reserves the right to redeem
  shares by the delivery, in whole or in part, of readily marketable
  securities instead of cash when a shareholder's redemption proceeds total
  more than 10% of the net asset value of a Fund.

  The Investment Company reserves the right to change or waive the minimum
  amount for a redemption, which currently is $5,000.


  EXCHANGES OF FUND SHARES
    ----------------------------------------------------------------------------
   
  A shareholder may exchange shares of one Fund for shares of another Fund. An
  exchange is the redemption of the shares from one Fund and the application
  of the redemption proceeds to the immediate purchase of shares of another
  Fund.

  The Investment Company may terminate or modify the terms of the exchange
  privilege upon 30 days' written notice to shareholders. The Investment
  Company may refuse to implement the purchase side of any exchange request
  that it concludes is based on a market timing or asset allocation strategy
  if the Investment Company determines the exchange would be disruptive to a
  Fund.

  The Investment Company reserves the right to change or waive the minimum
  amount for an exchange, which currently is $5,000.


  HOW TO PLACE A REDEMPTION OR EXCHANGE ORDER
    ----------------------------------------------------------------------------
   
  WHO MAY GIVE AN ORDER:   Only a shareholder's authorized person using a
                           Personal Identification Number ("PIN") that we have
                           assigned may place a redemption order or exchange
                           order. A shareholder must list authorized persons in
                           the initial application to purchase Fund shares, an
                           amended application, or in another written form that
                           is acceptable to the Investment Company.

  MINIMUM AMOUNT:          A redemption or exchange order must be for at least
                           $5,000.

  ORDERS BY TELEPHONE:
                           A shareholder may place a redemption or exchange
                           order by telephone if the shareholder elected the
                           option for telephone orders in its initial
                           application to purchase Fund shares or in an amended
                           application.


                           A shareholder should call the Investment Company at
                           1-800-914-8716 between the hours of 9:00 am and 8:00
                           p.m. Eastern Time, Monday through Friday on any
                           Valuation Day to place an order. If a shareholder
                           places a redemption or exchange order after 4:00
                           p.m. Eastern Time on a Valuation Day or on a day
                           that is not a Valuation Day, the order will be
                           considered received on the next Valuation Day.


                           The Investment Company will verify the shareholder's
                           name, the PIN assigned by the Investment Company to
                           the authorized person calling for the account, the
                           shareholder's account number, and record telephone
                           requests.

                           The Investment Company and the Funds' transfer agent
                           will not be liable for any losses or expenses
                           resulting from any telephone redemption or exchange
                           order reasonably believed to be genuine or for the
                           inability of a shareholder to make a telephone
                           request on any particular day. The Investment
                           Company reserves the right to add to or modify its
                           procedures in the future.

  ORDERS IN WRITING:
                           A shareholder may make a redemption or exchange
                           request in writing. The shareholder must specify the
                           account name, the account number, the Fund from
                           which shares are to be redeemed, the dollar amount
                           or number of shares to be redeemed, and for exchange
                           orders, the Fund or Funds whose shares will be
                           purchased with the exchange proceeds.

                           The necessary authorized person(s) must sign the
                           order, and each signer should print his or her name
                           and title under the signature.

                           A shareholder should send a written request to
                           Mutual of America Institutional Funds, Inc., 320
                           Park Avenue, New York, New York 10022. A shareholder
                           may send a written request to the Regional Office of
                           the Distributor, which will foward the request to
                           the Investment Company. The Valuation Day for the
                           order will be the Valuation Day the Investment
                           Company receives the request at its 320 Park Avenue
                           offices.

  REDEMPTION PROCEEDS:     A shareholder will receive redemption proceeds by
                           wire transfer of Federal Funds to the bank account
                           stated in the shareholder's initial application, or
                           in an amended application. An authorized person may
                           not specify a different bank account by telephone.

  EXCHANGE PROCEEDS:       The proceeds from the shares of the Fund being
                           exchanged are immediately
                           applied for the purchase of shares in another Fund.


  SHAREHOLDER REPORTS AND CONFIRMATION STATEMENTS
    ----------------------------------------------------------------------------
   
  The Investment Company will send each shareholder a quarterly statement,
  which will include Fund shares purchased, exchanged or redeemed during the
  month, the net asset value per share and total dollar amount for each
  transaction, and the shareholder's account balance in each Fund at the end
  of the period.

  The Investment Company, on behalf of the Distributor, will send to
  shareholders confirmation statements for each purchase, exchange or
  redemption transaction. A confirmation statement will show the Fund, number
  of shares, order date, net asset value per share and dollar amount for the
  transaction. A shareholder must report any error on a confirmation statement
  within two weeks after the mailing or other transmission of the statement to
  the shareholder.


  DIVIDENDS, CAPITAL GAINS DISTRIBUTIONS AND TAXATION OF FUNDS
    ----------------------------------------------------------------------------
   
  For each Fund, the Investment Company declares dividends at the end of June
  and end of December to pay out substantially all of the Fund's net
  investment income (dividends) and declares dividends at the end of December
  to pay out substantially all of the Fund's net realized short and long term
  capital gains (capital gains distributions). A Fund may make a special
  distribution in September of each year to comply with Federal tax law
  requirements for mutual funds.

     A shareholder may elect, in its application to purchase Fund shares or in
an amended application, to:

    o   automatically reinvest dividends and distributions from a Fund in
        additional shares of the Fund;

    o   receive dividends and distributions in cash; or

    o   automatically reinvest dividends from any Fund in shares of the Money
        Market Fund.

  The Investment Company is not subject to Federal income tax on ordinary
  income and net realized capital gains that it distributes to shareholders,
  as long as the distributions meet Federal tax law requirements for amount
  and source of income. Each Fund is treated as a separate corporation for
  Federal income tax purposes and must satisfy the tax requirements
  independently.

  SHAREHOLDER TAXATION
    ----------------------------------------------------------------------------
   
  Each shareholder should consult its own tax adviser about the Federal, state
  and local tax consequences of investing in Fund shares, because investors'
  tax situations will vary. Below are general rules about Federal income
  taxation for an investor to consider.

  When a shareholder redeems (sells) shares of a Fund, including in an
  exchange transaction, the shareholder will have a gain or a loss on its
  investment in those shares.

    o   If the shareholder owned the shares sold for more than a year, it will
        have a capital gain or loss from the sale.

    o   If the shareholder owned the shares sold for less than a year, any gain
        will be considered ordinary income, and any loss will be subject to
        special tax rules.

  When a shareholder receives income dividends or capital gains distributions
  from a Fund, the shareholder (to the extent it is taxable) will owe tax on
  the amount received, even if the shareholder automatically reinvests the
  dividend or distribution in additional Fund shares.

    o   Ordinary income rates apply to a Fund's dividends of ordinary income and
        net realized short-term capital gains.

    o   Capital gain rates apply to a Fund's distributions of net realized
        long-term capital gains.

    o   A potential investor, depending on its tax situation, may want to
        consider the tax impact of purchasing Fund shares when the Fund is
        expected to pay dividends or distributions in the near future.

  WITHHOLDING FOR FEDERAL INCOME TAXES. A shareholder on its application to
  purchase Fund shares may make representations and provide information to be
  exempt from withholding for Federal income tax on the Investment Company's
  distributions and dividends and payment of redemption proceeds. Corporate
  shareholders and certain other entities named in the Internal Revenue Code
  are exempt from withholding under certain circumstances.

     The Investment Company will withhold for Federal income tax if:

    o   a shareholder has not provided a correct taxpayer identification number,
        or

    o   a shareholder has not made the certifications required to be exempt from
        withholding, or

    o   the Investment Company or the shareholder has been notified by the
        Internal Revenue Service that the shareholder is subject to back-up
        withholding.

  A shareholder may credit any amount withheld by the Investment Company
  against the Federal income tax liability
  of the shareholder.

  Each January, the Investment Company will provide reports to Fund
  shareholders of the Federal income tax status of distributions and dividends
  made by the Funds during the previous year.

 FINANCIAL HIGHLIGHTS


  The financial highlights tables are intended to help you understand the
  Funds' financial performance. They show performance for the period of a
  Fund's operations, because the Funds have operated less than five years.
  Certain information reflects financial results for a single Fund share.

  The total returns in the table represent the rate that an investor would
  have earned or lost on an investment in the particular Fund (assuming
  reinvestment of all dividends and distributions). This information has been
  audited by Arthur Andersen LLP, whose report, along with the Investment
  Company's financial statements, are included in the annual report, which is
  available upon request.

                    INVESTMENT COMPANY'S FORM OF OPERATIONS


  HISTORY AND OPERATING FORM
    ----------------------------------------------------------------------------
   
  Mutual of America Institutional Funds, Inc. (the INVESTMENT COMPANY) was
  formed on October 27, 1994 as a Maryland corporation. It is a diversified,
  open-end management investment company registered under the Investment
  Company Act of 1940 (THE 1940 ACT).

  The Investment Company issues separate classes (or series) of stock, each of
  which represents a separate Fund of investments. There are currently four
  Funds: the Equity Index Fund, All America Fund, Bond Fund and Money Market
  Fund.


  OFFERING OF SHARES
    ----------------------------------------------------------------------------
   
  The Investment Company is designed primarily as an investment vehicle for
  endowments, foundations, corporations, municipalities or other public
  entities and other institutional investors. Currently, the Investment
  Company requires a minimum initial investment of $25,000, except that the
  Investment Company may waive this requirement in its discretion. The minimum
  amount for additional purchases of Fund shares currently is $5,000.

  Shares of the Fund are offered on a continuous basis. There is no sales
  charge or deferred sales charge for the purchase of Fund shares.

  As of the date of this Statement of Additional Information, substantially
  all of the outstanding shares of the All America and Bond Funds, and a
  significant portion of the shares of the Money Market Fund, were owned by
  Mutual of America Life Insurance Company (MUTUAL OF AMERICA LIFE), the
  indirect parent corporation of the Adviser, which made the initial
  investment for the Investment Company's operations. Mutual of America Life
  and its wholly-owned subsidiary, The American Life Insurance Company of New
  York (AMERICAN LIFE) are providing the initial investment for the Equity
  Index Fund. As of May 1, 1999 when the Equity Fund begins operations, Mutual
  of America Life and American Life will own 100% of the Equity Fund's shares.
   


  DESCRIPTION OF SHARES
    ----------------------------------------------------------------------------
   
  The authorized capital stock of the Investment Company consists of one
  billion shares of common stock, $.01 par value. The Investment Company
  currently has four classes of common stock, and it may establish additional
  classes and allocate its authorized shares either to new classes or to one
  or more of the existing classes.

  The Investment Company reserves the right to redeem, upon not less than 30
  days' written notice, all shares in a shareholder's Fund account when the
  aggregate value of the shares is less than $5,000.

  All shares of common stock, of whatever class, are entitled to one vote. The
  votes of all classes are cast on an aggregate basis, except that if the
  interests of the Funds differ, the voting is on a Fund-by-Fund basis.
  Examples of matters that would require a Fund-by-Fund vote are changes in
  the fundamental investment policy of a particular Fund and approval of the
  Investment Advisory Agreement or a Subadvisory Agreement for the Fund.

  The Investment Company is not required to hold annual meetings. It will call
  a special meeting of shareholders when a meeting is requested by
  shareholders holding at least 25% of the outstanding shares of the
  Investment Company entitled to vote at the meeting except that a meeting to
  remove one or more directors shall be called when requested by 10% of the
  outstanding shares of the Investment Company entitled to vote at the
  meeting.

  The shares of each Fund, when issued, will be fully paid and nonassessable
  and will have no preference, preemptive, conversion, exchange or similar
  rights. Shares do not have cumulative voting rights. Each issued and
  outstanding share in a Fund is entitled to participate equally in dividends
  and distributions declared by such Fund and, upon liquidation or
  dissolution, in the net assets of such Fund remaining after satisfaction of
  outstanding liabilities. Accrued liabilities which are not allocable to one
  or more Funds will generally be allocated among the Funds in proportion to
  their relative net assets. In the unlikely event that any Fund incurred
  liabilities in excess of its assets, each other Fund could be liable for
  such excess.

<PAGE>

    o   negotiable certificates of deposit, bank time deposits, bankers'
        acceptances and other short-term debt obligations of domestic banks and
        foreign branches of domestic banks and U.S. branches of foreign banks,

    o   repurchase agreements covering government securities, certificates of
        deposit, commercial paper or bankers' acceptances;

    o   variable amount floating rate notes; and

    o   debt securities issued by a corporation.

  The Money Market Fund may enter into transactions in options, futures
  contracts and options on futures, contracts
  on United States Treasury securities.

  Under the Money Market Fund's investment policy, MONEY MARKET INSTRUMENTS
  AND OTHER SHORT-TERM DEBT SECURITIES means securities that have a remaining
  term to maturity of up to 13 months (25 months in the case of government
  securities). The dollar-weighted average maturity of the securities held by
  the Money Market Fund will not exceed 90 days.

     The securities in the Money Market Fund must meet the following quality
requirements --

    o   All of the securities held by the Money Market Fund must have received
        (or be of comparable quality to securities which have received), at the
        time of the purchase, a rating in one of the two highest categories by
        any two nationally recognized statistical rating agencies; and

    o   At least 95% of the securities held by the Money Market Fund must have
        received (or be of comparable quality to securities which have
        received), at the time of purchase, a rating in the highest category by
        any two such rating agencies.

  The Board of Directors of the Investment Company must approve or ratify the
  purchase of any security (other than any U.S. government security) that has
  not received a rating or that has been rated by only one rating agency. The
  Fund will sell any securities that are subsequently downgraded below the two
  highest categories as soon as practicable, unless the Board of Directors
  determines that sale of those securities would not be in the best interests
  of the Fund.

  The Money Market Fund will not invest more than 5% of its total assets in
  securities of, or subject to puts from, any one issuer (other than
  government securities and repurchase agreements fully collateralized by
  government securities) provided that (x) the Fund may invest up to 10% of
  its total assets in securities issued or guaranteed by a single issuer with
  respect to which the Fund has an unconditional put and (y) with respect to
  25% of its total assets the Fund may, with respect to securities meeting the
  highest investment criteria, exceed the 5% limit for up to three business
  days.

  ADDITIONAL INVESTMENT STRATEGIES
    ----------------------------------------------------------------------------
  
     LENDING OF SECURITIES


  The Funds have the authority to lend their securities, under the conditions
  described below. The Funds will not lend any securities until the Investment
  Company's Board of Directors approves a form of securities lending
  agreement.

  A Fund may lend its securities, constituting up to 30% of its total assets,
  to brokers, dealers and financial institutions, other than any affiliate of
  the Investment Company. A Fund may pay reasonable fees to persons
  unaffiliated with the Fund for services or for arranging such loans.

  Upon lending securities, a Fund must receive as collateral cash, securities
  issued or guaranteed by the United States Government or its agencies or
  instrumentalities, or letters of credit of certain banks selected by the
  Adviser. The collateral amount at all times while the loan is outstanding
  must be maintained in amounts equal to at least 100% of the current market
  value of the loaned securities.

  The Fund will continue to receive interest or dividends on the securities
  lent. In addition, it will receive a portion of the income generated by the
  short-term investment of cash received as collateral, or, alternatively,
  where securities or a letter of credit are used as collateral, a lending fee
  paid directly to the Fund by the borrower of the securities. A Fund will
  have the right to terminate a securities loan at any time. The Fund will
  have the right to regain record ownership of loaned securities in order to
  exercise beneficial rights, such as voting rights or subscription rights.

  Loans of securities will be made only to firms that the Adviser deems
  creditworthy. There are risks of delay in recovery and even loss of rights
  in the collateral, however, if the borrower of securities defaults, becomes
  the subject of bankruptcy proceedings or otherwise is unable to fulfill its
  obligations or fails financially.


     REPURCHASE AGREEMENTS

  The Funds have the authority to enter into repurchase agreements. A Fund may
  not invest more than 10% of its total assets in repurchase agreements or
  time deposits that mature in more than seven days. The Funds will not enter
  into any repurchase agreements until the Investment Company's Board of
  Directors approves a form of Repurchase Agreement and authorizes entities as
  counterparties.

  Under a repurchase agreement, a Fund acquires underlying debt instruments
  for a relatively short period (usually not more than one week and never more
  than one year) subject to an obligation of the seller to repurchase (and the
  Fund to resell) the instrument at a fixed price and time, thereby
  determining the yield during the Fund's holding period. This results in a
  fixed rate of return insulated from market fluctuation during such period.
  Accrued interest on the underlying security will not be included for
  purposes of valuing a Fund's assets.

  Repurchase agreements have the characteristics of loans by a Fund and will
  be fully collateralized (either with physical securities or evidence of book
  entry transfer to the account of the custodian bank) at all times. During
  the term of the repurchase agreement, the Fund retains the security subject
  to the repurchase agreement as collateral securing the seller's repurchase
  obligation, continually monitors the market value of the security subject to
  the agreement and requires the Fund's seller to deposit with the Fund
  additional collateral equal to any amount by which the market value of the
  security subject to the repurchase agreement falls below the resale amount
  provided under the repurchase agreement.

  The Funds will enter into repurchase agreements only with member banks of
  the Federal Reserve System and with dealers in U.S. Government securities
  whose creditworthiness has been reviewed and found satisfactory by the
  Adviser and the Board of Directors of the Investment Company.

  Securities underlying repurchase agreements will be limited to certificates
  of deposit, commercial paper, bankers' acceptances, or obligations issued or
  guaranteed by the United States Government or its agencies or
  instrumentalities, in which the Funds may otherwise invest.

  A seller of a repurchase agreement could default and not repurchase from a
  Fund the security that is the subject of the agreement. The Fund would look
  to the collateral underlying the seller's repurchase agreement, including
  the securities subject to the repurchase agreement, for satisfaction of the
  seller's obligation to the Fund. In such event, the Fund might incur
  disposition costs in liquidating the collateral and might suffer a loss if
  the value of the collateral declines. There is a risk that if the issuer of
  the repurchase agreement becomes involved in bankruptcy


                                      -5-
<PAGE>

  proceedings, the Fund might be delayed or prevented from liquidating the
  underlying security or otherwise obtaining it for its own purposes, if the
  Fund did not have actual or book entry possession of the security.


     RULE 144A INVESTMENTS, SECTION 4(2) COMMERCIAL PAPER AND ILLIQUID
SECURITIES

  Each Fund, with respect to not more than 10% of its total assets, may
  purchase securities that are not readily marketable, or are "illiquid".
  Repurchase agreements of more than seven days' duration and variable and
  floating rate demand notes not requiring receipt of the principal note
  amount within seven days' notice are considered illiquid. A Fund may incur
  higher transaction costs and require more time to complete transactions for
  the purchase and sale of illiquid securities than for readily marketable
  securities.

  The Adviser will make a factual determination as to whether securities with
  contractual or legal restrictions on resale purchased by a Fund are liquid,
  based on the frequency of trades and quotes, the number of dealers and
  potential purchasers, dealer undertakings to make a market, and the nature
  of the security and the marketplace, pursuant to procedures adopted by the
  Board of Directors of the Investment Company.

  Securities that are eligible for purchase and sale under Rule 144A of the
  Securities Act of 1933 (the "1933 Act") shall be considered liquid, provided
  the Adviser has not made a contrary determination regarding liquidity in
  accordance with the Board's procedures. Rule 144A permits certain qualified
  institutional buyers to trade in securities even though the securities are
  not registered under the 1933 Act. In addition, commercial paper privately
  placed in accordance with Section 4(2) of the 1933 Act also will be
  considered liquid, provided the requirements set forth in the Board's
  procedures are satisfied.


     OPTIONS AND FUTURES CONTRACTS

  Each of the Funds may purchase and sell options and futures contracts, as
  described below, as long as the contracts are traded on a domestic exchange.
  Each of the Funds may:

    o   Sell a call option contract on a security it holds in its portfolio
        (called a covered call), and it may buy a call option contract on the
        security to close out a position created by the sale of a covered call;
         

    o   Buy a put option contract on a security it holds in its portfolio, and
        it may sell a put option contract on the security to close out a
        position created by the purchase of the put option contract;

    o   Purchase and sell futures contracts, and purchase options on futures
        contracts, on fixed-income securities; and

    o   Purchase and sell futures contracts, and purchase options on futures
        contracts, on indexes of securities.

  A Fund may use futures contracts to protect against general increases or
  decreases in the levels of securities prices, in the manner described below.

    o   When a Fund anticipates a general decrease in the market value of
        portfolio securities, it may sell futures contracts. If the market value
        falls, the decline in the Fund's net asset value may be offset, in whole
        or in part, by corresponding gains on the futures position.


        - A Fund may sell futures contracts on fixed-income securities in
          anticipation of a rise in interest rates, that would cause a decline
          in the value of fixed-income securities held in the Fund's portfolio.
           

        - A Fund may sell stock index futures contracts in anticipation of a
          general market wide decline that would reduce the value of its
          portfolio of stocks.

    o   When a Fund projects an increase in the cost of fixed-income securities
        or stocks to be acquired in the future, the Fund may purchase futures
        contracts on fixed-income securities or stock indexes. If the hedging
        transaction is successful, the increased cost of securities subsequently
        acquired may be offset, in whole or in part, by gains on the futures
        position.

    o   Instead of purchasing or selling futures contracts, a Fund may purchase
        call or put options on futures contracts in order to protect against
        declines in the value of portfolio securities or against increases in
        the cost of securities to be acquired.


                                      -6-
<PAGE>

        - Purchases of options on futures contracts may present less risk in
          hedging a portfolio than the purchase and sale of the underlying
          futures contracts, since the potential loss is limited to the amount
          of the premium paid for the option, plus related transaction costs.

        - As in the case of purchases and sales of futures contracts, a Fund
          may be able to offset declines in the value of portfolio securities,
          or increases in the cost of securities acquired, through gains
          realized on its purchases of options on futures.

    o   The Funds also may purchase put options on securities or stock indexes
        for the same types of hedging purposes. The purchase of a put option on
        a security or stock index permits a Fund to protect against declines in
        the value of the underlying security or securities in a manner similar
        to the sale of futures contracts.

    o   In addition, the Funds may write call options on portfolio securities or
        on stock indexes for the purpose of increasing their returns and/or to
        protect the value of their portfolios.


        - When a Fund writes an option which expires unexercised or is closed
          out by the Fund at a profit, it will retain the premium paid for the
          option, less related transaction costs, which will increase its gross
          income and will offset in part the reduced value of a portfolio
          security in connection with which the option may have been written.

        - If the price of the security underlying the option moves adversely to
          the Fund's position, the option may be exercised and the Fund will be
          required to sell the security at a disadvantageous price, resulting
          in losses which may be only partially offset by the amount of the
          premium.

        - A call option on a security written by a Fund will be covered through
          ownership of the security underlying the option or through ownership
          of an absolute and immediate right to acquire such security upon
          conversion or exchange of other securities held in its portfolio.


     RISKS IN FUTURES AND OPTIONS TRANSACTIONS INCLUDE THE FOLLOWING:

    o   There may be a lack of liquidity, which could make it difficult or
        impossible for a Fund to close out existing positions and realize gains
        or limit losses.

        The liquidity of a secondary market in futures contracts or options on
        futures contracts may be adversely affected by "daily price fluctuation
        limits," established by the exchanges on which such instruments are
        traded, which limit the amount of fluctuation in the price of a
        contract during a single trading day. Once the limit in a particular
        contract has been reached, no further trading in such contract may
        occur beyond such limit, thus preventing the liquidation of positions,
        and requiring traders to make additional variation margin payments.
        Market liquidity in options, futures contracts or options on futures
        contracts may also be adversely affected by trading halts, suspensions,
        exchange or clearing house equipment failures, government intervention,
        insolvency of a brokerage firm or clearing house or other disruptions
        of normal trading activity.

    o   The securities held in a Fund's portfolios may not exactly duplicate the
        security or securities underlying the options, futures contracts or
        options on futures contracts traded by the Fund, and as a result the
        price of the portfolio securities being hedged will not move in the same
        amount or direction as the underlying index, securities or debt
        obligation.

    o   A Fund purchasing an option may lose the entire amount of the premium
        plus related transaction costs.

    o   For options on futures contracts, changes in the value of the underlying
        futures contract may not be fully reflected in the value of the option.

    o   With respect to options and options on futures contracts, the Funds are
        subject to the risk of market movements between the time that the option
        is exercised and the time of performance thereunder.

    o   In writing a covered call option on a security or a stock index, a Fund
        may incur the risk that changes in the value of the instruments used to
        cover the position will not correlate precisely with changes in the
        value of the option or underlying the index or instrument.

    o   The opening of a futures position and the writing of an option are
        transactions that involve substantial leverage. As a result, relatively
        small movements in the price of the contract can result in substantial
        unrealized gains or losses.


                                      -7-
<PAGE>

  A CALL OPTION is a short-term contract (generally having a duration of nine
  months or less) which gives the purchaser of the option the right to
  purchase the underlying security at a fixed exercise price at any time prior
  to the expiration of the option regardless of the market price of the
  security during the option period. As consideration for the call option, the
  purchaser pays a Fund (the seller) a premium, which the Fund retains whether
  or not the option is exercised. The seller of the call option has the
  obligation, upon the exercise of the option by the purchaser, to sell the
  underlying security at the exercise price at any time during the option
  period. The selling of a call option will benefit a Fund if, over the option
  period, the underlying security declines in value or does not appreciate
  above the aggregate of the exercise price and the premium. However, the Fund
  risks an "opportunity loss" of profits if the underlying security
  appreciates above the aggregate value of the exercise price and the premium.
   

  A PUT OPTION is a similar short-term contract that gives the purchaser of
  the option the right to sell the underlying security at a fixed exercise
  price at any time prior to the expiration of the option regardless of the
  market price of the security during the option period. As consideration for
  the put option a Fund (the purchaser) pays the seller a premium, which the
  seller retains whether or not the option is exercised. The seller of the put
  option has the obligation, upon the exercise of the option by the purchaser,
  to purchase the underlying security at the exercise price at any time during
  the option period. The buying of a covered put contract limits the downside
  exposure for the investment in the underlying security to the combination of
  the exercise price less the premium paid. The risk of purchasing a put is
  that the market price of the underlying stock prevailing on the expiration
  date may be above the option's exercise price. In that case the option would
  expire worthless and the entire premium would be lost.

  In addition to options (both calls and puts) on individual securities, the
  Funds may purchase and sell OPTIONS ON INDEXES OF SECURITIES such as the
  Standard & Poor's 100 Index, the Standard & Poor's 500 Index and the New
  York Stock Exchange Composite Index. Options on stock indexes, like options
  on individuals securities, are traded on national securities exchanges, such
  as the Chicago Board Options Exchange, the American Stock Exchange and the
  New York Stock Exchange.

  A FUTURES CONTRACT ON FIXED INCOME SECURITIES requires the seller to
  deliver, and the purchaser to accept delivery of, a stated quantity of a
  given type of fixed income security for a fixed price at a specified time in
  the future. A futures contract or option on a stock index provides for the
  making and acceptance of a cash settlement equal to the change in value of a
  hypothetical portfolio of stocks between the time the contract is entered
  into and the time it is liquidated, times a fixed multiplier. Futures
  contracts may be traded domestically only on exchanges which have been
  designated as "contract markets" by the Commodity Futures Trading Commission
  ("CFTC"), such as the Chicago Board of Trade.

  An OPTION ON A FUTURES CONTRACT provides the purchaser with the right, but
  not the obligation, to enter into a "long" position in the underlying
  futures contract (in the case of a call option on a futures contract), or a
  "short" position in the underlying futures contract (in the case of a put
  option on a futures contract), at a fixed price up to a stated expiration
  date. Upon exercise of the option by the holder, the contract market
  clearing house establishes a corresponding short position for the writer of
  the option, in the case of a call option, or a corresponding long position
  in the case of a put option. In the event that an option is exercised, the
  parties are subject to all of the risks associated with the trading of
  futures contracts, such as payment of margin deposits.

  A Fund does not pay or receive a payment upon its purchase or sale of a
  futures contract. Initially, a Fund will be required to deposit with the
  Fund's custodian in the broker's name an amount of cash or U.S. Treasury
  bills equal to approximately 5% of the contract amount. This amount is known
  as "initial margin."

  While a futures contract is outstanding, there will be subsequent payments,
  called "maintenance margin", to and from the broker. These payments will be
  made on a daily or intraday basis as the price of the underlying instrument
  or stock index fluctuates making, the long and short positions in the
  futures contract more or less valuable. This process is known as "mark to
  market. At any time prior to expiration of the futures contract, a Fund may
  elect to close the position by taking an opposite position, which will
  operate to terminate the Fund's position in the futures contract. A final
  determination of margin is then made, additional cash is required to be paid
  by or released to the Fund, and the Fund realizes a loss or a gain.

  ADDITIONAL INFORMATION ABOUT SPECIFIC TYPES OF SECURITIES
    ----------------------------------------------------------------------------
   
     NON-INVESTMENT GRADE SECURITIES


  The Bond Fund may purchase non-investment grade debt securities. In
  addition, the Bond Fund and the other Funds that purchase debt securities
  may hold a security that becomes non-investment grade as a result of
  impairments of the issuer's credit.

  Fixed-income securities that are rated in the lower rating categories of the
  nationally recognized rating services (Ba or lower by Moody's and BB or
  lower by Standard & Poor's), or unrated securities of comparable quality,
  are commonly known as non-investment grade securities or "junk bonds". Junk
  bonds are regarded as being predominantly speculative as to the issuer's
  ability to make payments of principal and interest. Investment in
  non-investment grade securities involves substantial risk. Junk bonds may be
  issued by less creditworthy companies or by larger, highly leveraged
  companies, and are frequently issued in corporate restructurings, such as
  mergers and leveraged buy-outs. Such securities are particularly vulnerable
  to adverse changes in the issuer's industry and in general economic
  conditions. Junk bonds frequently are junior obligations of their issuers,
  so that in the event of the issuer's bankruptcy, claims of the holders of
  junk bonds will be satisfied only after satisfaction of the claims of senior
  security holders.

  Non-investment grade bonds tend to be more volatile than higher-rated
  fixed-income securities, so that adverse economic events may have a greater
  impact on the prices of junk bonds than on higher-rated fixed-income
  securities. Junk bonds generally are purchased and sold through dealers who
  make a market in such securities for their own accounts. However, there are
  fewer dealers in the non-investment grade bond market, and the market may be
  less liquid than the market for higher-rated fixed-income securities, even
  under normal economic conditions. Also, there may be significant disparities
  in the prices quoted for junk bonds by various dealers. Adverse economic
  conditions or investor perceptions (whether or not based on economic
  fundamentals) may impair the liquidity of this market, and may cause the
  prices that a Fund may receive for any non-investment grade bonds to be
  reduced, or might cause a Fund to experience difficulty in liquidating a
  portion of its portfolio.

  The Investment Company currently anticipates than no Fund will invest more
  than 5% of its total assets in non-investment grade debt securities.


     U.S. GOVERNMENT AND U.S. GOVERNMENT AGENCY OBLIGATIONS

  All of the Funds may invest in U.S. Government and U.S. Government agency
  obligations. Some of these securities also may be considered money market
  instruments. Some also may be mortgage-backed securities or zero coupon
  securities.

  U.S. GOVERNMENT OBLIGATIONS: These securities are issued or guaranteed as to
  principal and interest by the United States Government. They include a
  variety of Treasury securities, which differ only in their interest rates,
  maturities and times of issuance. Treasury bills have a maturity of one year
  or less. Treasury notes have maturities of one to seven years and Treasury
  bonds generally have a maturity of greater than five years.

  U.S. GOVERNMENT AGENCY OBLIGATIONS: Agencies of the United States Government
  that issue or guarantee obligations include, among others, Export-Import
  Bank of the United States, Farmers Home Administration, Federal Housing
  Administration, Government National Mortgage Association, Student Loan
  Marketing Association, Maritime Administration, Small Business
  Administration and the Tennessee Valley Authority. Instrumentalities of the
  United States Government that issue or guarantee obligations include, among
  others, Federal Farm Credit Banks, Federal National Mortgage Association,
  Federal Home Loan Banks, Federal Home Loan Mortgage Corporation, Federal
  Intermediate Credit Banks, Federal Land Banks and Banks for Cooperatives.

  Some of the securities issued by U.S. Government agencies and
  instrumentalities are supported by the full faith and credit of the U.S.
  Treasury; others are supported by the right of the issuer to borrow from the
  Treasury, while others are supported only by the credit of the
  instrumentality that issued the obligation.


     MONEY MARKET INSTRUMENTS

     All of the Funds may purchase money market instruments, which include the
following.

  CERTIFICATES OF DEPOSIT. Certificates of deposit are generally short term,
  interest-bearing negotiable certificates issued by banks or savings and loan
  associations against funds deposited in the issuing institution.

  TIME DEPOSITS. Time deposits are deposits in a bank or other financial
  institution for a specified period of time at fixed interest rate, for which
  no negotiable certificate is received.


                                      -9-
<PAGE>

  BANKERS' ACCEPTANCE. A bankers' acceptance is a 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.

  COMMERCIAL PAPER. Commercial paper 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 FLOATING RATE NOTES. Variable floating rate notes are
  short-term, unsecured promissory notes issued by corporations to finance
  short-term credit needs. These are interest-bearing notes on which the
  interest rate generally fluctuates on a weekly basis.

  CORPORATE DEBT SECURITIES. Corporate debt securities with a remaining
  maturity of less than one year tend to become extremely liquid and are
  traded as money market securities.

     TREASURY BILLS. See "U.S. Government and U.S. Government Agency
Obligations" above.


     ZERO COUPON SECURITIES AND DISCOUNT NOTES; REDEEMABLE SECURITIES

  The Bond Fund, and the All America Fund to the extent it invests in fixed
  income securities, may invest in discount notes and zero coupon securities.
  Discount notes mature in one year or less from the date of issuance. Zero
  coupon securities may be issued by corporations or by certain U.S.
  Government agencies.

  Discount notes and zero coupon securities do not pay interest. Instead, they
  are issued at prices that are discounted from the principal (par) amount due
  at maturity. The difference between the issue price and the principal amount
  due at maturity (or the amount due at the expected redemption date in some
  cases if the securities are callable) is called "original issue discount". A
  Fund must accrue original issue discount as income, even if the Fund does
  not actually receive any payment under the security during the accrual
  period. The purchase price paid for zero coupon securities at the time of
  issuance, or upon any subsequent resale, reflects a yield-to-maturity
  required by the purchaser from the purchase date to the maturity date (or
  expected redemption date).


     FOREIGN SECURITIES

  In addition to investing in domestic securities, each of the Funds other
  than the Equity Index Fund and the Money Market Fund, may invest in
  securities of foreign issuers, including securities traded outside the
  United States. Foreign issues guaranteed by domestic corporations are
  considered to be domestic securities.

  The Investment Company has a fundamental investment restriction that limits
  foreign securities, including foreign exchange transactions, to 20% of a
  Fund's total assets. (See "Fundamental Investment Restrictions", paragraph
  2.) The Investment Company currently anticipates that no Fund will invest
  more than 10% of its total assets in foreign securities or foreign exchange
  transactions.

     The Investment Company will consider special factors before investing in
foreign securities. These include:

    o   Year 2000 preparedness by the issuer and the foreign exchange where the
        security is traded,

    o   changes in currency rates or currency exchange control regulations,

    o   the possibility of expropriation,

    o   the unavailability of financial information or the difficulty of
        interpreting financial information prepared under foreign accounting
        standards,

    o   less liquidity and more volatility in foreign securities markets,

    o   the impact of political, social or diplomatic developments, and

    o   the difficulty of assessing economic trends in foreign countries.

  The Funds could encounter greater difficulties in bringing legal processes
  abroad than would be encountered in the United States. In addition,
  transaction costs in foreign securities may be higher.


                                      -10-
<PAGE>

  AMERICAN DEPOSITARY RECEIPTS

  ADRs are dollar-denominated receipts issued generally by domestic banks and
  representing the deposit with the bank of a security of a foreign issuer.
  ADRs are publicly traded on exchanges or over-the-counter in the United
  States. ADRs are not considered foreign securities for purposes of the
  restriction on the amount of foreign securities.

     The Investment Company will consider special factors before investing in
ADRs: These include:

    o   Year 2000 preparedness by the issuer,

    o   changes in currency rates or currency exchange control regulations,

    o   the possibility of expropriation,

    o   the unavailability of financial information or the difficulty of
        interpreting financial information prepared under foreign accounting
        standards,

    o   the impact of political, social or diplomatic developments, and

    o   the difficulty of assessing economic trends in foreign countries.


  CONVERTIBLE SECURITIES

  The Bond Fund, as well as the All America Fund to the extent it invests in
  debt securities, may invest in convertible securities, which normally
  provide a higher yield than the underlying stock but a lower yield than a
  fixed-income security without the convertibility feature. The price of the
  convertible security normally will vary to some degree with changes in the
  price of the underlying stock, although the higher yield tends to make the
  convertible security less volatile than the underlying common stock. The
  price of the convertible security also will vary to some degree inversely
  with interest rates.


  EQUIPMENT TRUST CERTIFICATES

  The Bond Fund, as well as the All America Fund to the extent it invests in
  debt securities, may invest in equipment trust certificates. The proceeds of
  those certificates are used to purchase equipment, such as railroad cars,
  airplanes or other equipment, which in turn serve as collateral for the
  related issue of certificates.

  The equipment subject to a trust generally is leased by a railroad, airline
  or other business, and rental payments provide the projected cash flow for
  the repayment of the equipment trust certificates. Holders of equipment
  trust certificates must look to the collateral securing the certificates,
  and any guarantee provided by the lessee or any parent corporation for the
  payment of lease amounts, in the case of default in the payment of principal
  and interest on the certificates.

  The Investment Company currently anticipates that no Fund will invest more
  than 5% of its total assets in equipment trust certificates.


  ASSET-BACKED SECURITIES

  The Bond Fund, as well as the All America Fund to the extent it invests in
  debt securities, may invest in securities backed by consumer or credit card
  loans or other receivables or may purchase interests in pools of such
  assets.

  Changes in interest rates may significantly affect the value of these
  securities, and prepayment rates will impact the yield and price of the
  securities. A decline in interest rates may result in increases in
  prepayment, although asset-backed securities generally are not expected to
  prepay to the same extent as mortgage-backed securities in such
  circumstances. An increase in interest rates may result in prepayment at a
  rate slower than was assumed when the security was purchased. The
  creditworthiness of an issuer of asset-backed securities also may impact the
  value of they securities.

  The Investment Company currently anticipates that no Fund will:

    o   invest more than 10% of its total assets in asset-backed securities,

    o   invest in interest-only strips or principal-only strips ("IOs" or "POs")
        of asset-backed securities, or

    o   purchase the final or most speculative tranche of asset-backed
        securities issues.

                                      -11-
<PAGE>

  MORTGAGE-BACKED SECURITIES

  The Bond Fund, as well as the All America Fund to the extent it invests in
  debt securities, may invest in mortgage-backed securities. You should refer
  to the discussion of Mortgage-Backed Securities in the Prospectus under
  "Details about How Our Funds Invest and Related Risks -- Specific
  Investments or Strategies and Related Risks".

  The Investment Company currently anticipates that no Fund will:

    o   invest more than 10% of its total assets in mortgage-backed securities
        that are not also considered to be U.S. Government or U.S. Government
        agency securities,

    o   invest in interest-only strips or principal-only strips ("IOs" or "POs")
        of mortgage-backed securities, or

    o   purchase the final or most speculative tranche of CMO or other
        mortgage-backed securities issues.


  WARRANTS

  The All America Fund and Bond Fund may acquire warrants. A warrant is an
  option to purchase common stock of an issuer and is issued in conjunction
  with another security, such as a debt obligation. A warrant specifies the
  price at which the holder may purchase shares of common stock and usually
  expires after a period of time. A warrantholder generally has the option of
  paying cash for the common stock to be purchased or of surrendering a
  portion of the security already owned (such as a debt obligation).

  The common stock underlying a warrant may not increase in value after the date
  the warrant was issued, or may not increase up to the warrant exercise price.
  In this case, the warrant generally would have little value and could expire
  unexercised.

  The Investment Company currently anticipates that no Fund will invest more
  than 5% of its assets in warrants.


  PREFERRED STOCK

  The All America Fund and Bond Fund may purchase preferred stock. A
  corporation may issue a form of equity security called preferred stock.
  Compared to common stock, preferred stock has advantages in the receipt of
  dividends and in the receipt of the corporation's assets upon liquidation.
  Preferred stockholders, however, usually do not have voting rights at
  meetings of the corporation's shareholders.

  An issuer of preferred stock must pay a dividend to holders of preferred
  stock before it distributes a dividend to holders of common stock. When a
  corporation issues preferred stock, it sets a dividend rate, or a formula to
  determine the rate. If a corporation does not have sufficient earnings to
  pay the specified dividend to preferred stockholders, the unpaid dividend
  may accrue (cumulate) and become payable when the corporation's earnings
  increase. Bondholders, in contrast, are entitled to receive interest and
  principal due, regardless of the issuer's earnings.

  Some issues of preferred stock give the holder the right to convert the
  preferred stock into shares of common stock, when certain conditions are
  met. A holder of preferred stock that is not convertible, or of preferred
  stock that is convertible but has not met the conditions for conversion,
  does not share in the earnings of the issuer other than through the receipt
  of dividends on the preferred stock. The market value of convertible
  preferred stock generally fluctuates more than the market value of
  nonconvertible preferred stock, because the value of the underlying common
  stock will affect the price of the convertible stock.

  Preferred stock has the risk that a corporation may not have earnings from
  which to pay the dividends as they become due. Even if a corporation is
  paying dividends, if the dividend rate is fixed (and not variable), changes
  in interest rates generally will affect the market value of the preferred
  stock in the same manner as for debt obligations.

  The Investment Company presently anticipates that no Fund will invest more
  than 10% of its assets in preferred stock.

                      FUNDAMENTAL INVESTMENT RESTRICTIONS

  The following investment restrictions are fundamental policies and may not be
  changed without the approval of a majority of the outstanding voting shares of
  the affected Fund. No Fund will:

  1.  purchase or sell options or futures except those listed on a domestic
      exchange;

  2.  trade in foreign exchange, or invest in securities of foreign issuers if
      at the time of acquisition more than 20% of its total assets, taken at
      market value at the time of the investment, would be invested in such
      securities;

  3.  make an investment in order to exercise control of management over a
      company (either singly or together with any other Fund);

  4.  underwrite the securities of other companies;

  5.  make short sales, except when the Fund has, by reason of ownership of
      other securities, the right to obtain securities of equivalent kind and
      amount that will be held so long as they are in a short position;

  6.  purchase commodities or commodity contracts, except to the extent
      described in the Prospectus and herein with respect to futures and related
      options;

  7.  with respect to at least 75% of the value of its total assets, invest more
      than 5% of its total assets in the securities of any one issuer (including
      repurchase agreements with any one institution), other than securities
      issued or guaranteed by the United States Government or its agencies or
      instrumentalities;

  8.  with respect to at least 75% of the value of its total assets, purchase
      more than 10% of the outstanding voting securities of an issuer, except
      that such restriction shall not apply to securities issued or guaranteed
      by the United States Government or its agencies or instrumentalities;

  9.  issue senior securities, except that each Fund may borrow as described in
      restriction 13 below (the issuance and sale of options and futures not
      being considered the issuance of senior securities) and except as
      permitted by the rules and regulations of the Investment Company Act or an
      exemption thereunder and with any required approval of the shareholders of
      the Investment Company;

  10. make an investment in an industry if that investment would make the Fund's
      holding in that industry exceed 25% of the Fund's total assets, except
      that this policy does not apply to obligations issued or guaranteed by the
      U.S. Government or its agencies or instrumentalities;

  11. purchase real estate or mortgages directly, except that the All America
      Fund may buy shares of real estate investment trusts listed on stock
      exchanges or reported on the National Association of Securities Dealers
      Automated Quotation ("NASDAQ") system, and the Bond Fund may buy
      mortgage-backed debt issues;

  12. purchase any securities issued by any other investment company except as
      permitted under the Investment Company Act and in accordance with
      applicable state law;

  13. purchase any security on margin, except for short-term credit necessary
      for clearance of portfolio transactions or in connection with permitted
      options and futures contracts, or borrow money, except from banks for
      temporary purposes, or pledge its assets unless to secure such borrowing.
      The Funds may borrow money from or pledge their assets to banks in order
      to transfer funds for various purposes, as required, without interfering
      with the orderly liquidation of securities in their portfolios, but not
      for leveraging purposes. Such borrowings may not exceed 5% of the value of
      a Fund's total assets at market value;

  14. make loans, except loans of portfolio securities (not exceeding 30% of the
      value of its total assets at market value) or loans through entry into
      repurchase agreements (the purchase of publicly traded debt obligations
      not being considered the making of a loan);

  15. invest more than 10% of its total assets in repurchase agreements or time
      deposits maturing in more than seven days or in portfolio securities not
      readily marketable; or

  16. purchase oil, gas or mineral interests, except that the Funds may purchase
      securities of issuers that invest in oil, gas or mineral interests.

  If a percentage restriction is adhered to at the time of investment, a later
  increase or decrease in percentage beyond the specified limit resulting from
  a change in values of portfolio securities or amount of net assets will not
  be considered a violation.

  regular reports to the Board of Directors of the Investment Company,
  maintenance of records, and providing all the office space, facilities,

                           ADMINISTRATIVE AGREEMENTS

  ACCOUNTING AND RECORDKEEPING AGENT

  The Adviser serves as accounting and recordkeeping agent for the Funds.
  Under its Investment Accounting Agreement with the Investment Company, the
  Adviser performs accounting and recordkeeping functions related to portfolio
  transactions as required by the Investment Company Act, provides the
  Investment Company with accounting and related reports on a periodic basis,
  and calculates the net asset value of each Fund in the manner described in
  the Prospectus.

  As compensation for its services, the Adviser receives from each Fund a
  monthly base fee of $500 plus a monthly minimum fee of $2,000, or if an
  asset-based fee of .0225% of the Investment Company net assets would result
  in a fee greater than the aggregate of the Fund minimums, the Fund's
  proportion of the asset-based fee, and is reimbursed for out-of-pocket
  expenses it incurs in performing its services to the Investment Company. The
  Adviser has entered into an arrangement with Mutual of America for the
  provision of investment accounting and recordkeeping, legal and certain
  other services in connection with the Investment Company.


  TRANSFER AGENT

  State Street Bank and Trust Company, Boston, Massachusetts (STATE STREET)
  serves as transfer agent and dividend disbursing agent for Fund shares.
  Under its Transfer Agency and Service Agreement with the Investment Company,
  State Street is obligated to maintain shareholder accounts to reflect
  purchases and redemptions of Fund shares; prepare and transmit payments for
  dividends and distributions declared by the Investment Company; mail proxy
  materials, shareholder reports and prospectuses to current shareholders; and
  prepare and mail account and confirmation statements for shareholders.

  For its services, State Street receives from each Fund a monthly maintenance
  fee based on the number of holders of Fund shares, ranging from a minimum of
  $1,000 per month for 0-15 shareholders to $2,500 per month for 51-200
  shareholders, and a trade processing fee for each trade and is reimbursed
  for out-of-pocket expenses.

                     PORTFOLIO TRANSACTIONS AND BROKERAGE


  SELECTION OF BROKERS AND DEALERS
    ----------------------------------------------------------------------------
   
  The Adviser and each Subadviser are responsible for decisions to buy and
  sell securities for the Funds of the Investment Company for which they
  provide services as well as for selecting brokers and, where applicable,
  negotiating the amount of the commission rate paid.

    o   The Adviser and Subadvisers select broker-dealers which, in their best
        judgment, provide prompt and reliable execution at favorable security
        prices and reasonable commission rates.

    o   They may select broker-dealers which provide them with research services
        and may cause a Fund to pay such broker-dealers commissions which exceed
        those other broker-dealers may have charged, if in their view the
        commissions are reasonable in relation to the value of the brokerage
        and/or research services provided by the broker-dealer.

    o   When purchasing or selling securities trading on the over-the-counter
        market, the Adviser and Subadvisers will generally execute the
        transaction with a broker engaged in making a market for such
        securities.

    o   The Adviser and Subadvisers may place certain orders with their
        affiliates, subject to the requirements of the 1940 Act.

    o   No transactions may be effected by a Fund with an affiliate of the
        Adviser or a Sub-Adviser acting as principal for its own account.

  Brokerage commissions are negotiated, as there are no standard rates. All
  brokerage firms provide the service of execution of the order made. Some
  brokerage firms also provide research and statistical data, and research
  reports on particular companies and industries are customarily provided by
  brokerage firms to large investors.

  The Adviser, and each Subadviser, will place orders with brokers providing
  useful research and statistical data services if reasonable commissions can
  be negotiated for the total services furnished even though lower commissions
  may be available from brokers not providing such services. The Adviser, and
  each Subadviser, uses these services in connection with all of its
  investment activities, and some of the data or services obtained in
  connection with the execution of transactions for the Investment Company may
  be used in managing other investment accounts. Conversely, data or services
  obtained in connection with transactions in other accounts may be used by
  the Adviser, and each Subadviser, in providing investment advice to the
  Investment Company. To the extent that the Adviser, and each Subadviser,
  uses research and statistical data services so obtained, its expenses may be
  reduced and such data has therefore been and is one of the factors
  considered by the Adviser, and each Subadviser, in determining its fee for
  investment advisory services.

  At times, transactions for the Investment Company may be executed together
  with purchases or sales of the same security for other accounts of the
  Adviser or a Subadviser. When making concurrent transactions for several
  accounts, an effort is made to allocate executions fairly among them.
  Transactions of this type are executed only when the Adviser, or a
  Subadviser, believes it to be in the best interests of the affected Fund(s),
  as well as any other accounts involved. However, the possibility exists that
  concurrent executions may work out to the disadvantage of the Fund(s)
  involved.

  COMMISSIONS TO AFFILIATED BROKERS
    ----------------------------------------------------------------------------
   
  During the past three years, the Investment Company has paid brokerage
  commissions to Mutual of America Securities Corporation (SECURITIES
  CORPORATION), an affiliate of the Adviser, through an introducing brokerage
  arrangement with Bear Stearns Securities Corp., and to Fred Alger & Co.
  (FRED ALGER), an affiliate of Alger Management, Inc., as follows:

   1997 -- Fred Alger                  $18,793           37.6%                 30.8%
   1996 -- Fred Alger                  $ 5,490           10.7%                  5.8%
</TABLE>

  The purchases and sales placed for the Indexed Assets of the All America
  Fund, including through the Securities Corporation, related primarily to
  large capitalization stocks, many of which are included in the S&P 500
  Index. The purchases and sales placed through Fred Alger related primarily
  to stocks issued by companies with smaller market capitalizations, for which
  execution may be more difficult.


  PORTFOLIO TURNOVER
    ----------------------------------------------------------------------------
   
  The Adviser and the Subadvisers do not consider portfolio turnover rate to
  be a limiting factor when they deem it appropriate to purchase or sell
  securities for a Fund. The portfolio turnover rate for a Fund in any year
  will depend on market conditions, and the rate may increase depending on
  market conditions or if a new portfolio manager for a Fund restructures the
  Fund's holdings. The Insurance Companies' Separate Accounts do not pay taxes
  on the investment gains of the Funds. As a consequence, the Adviser and
  Subadvisers do not consider how long a Fund has held a security, or how
  capital gain upon sale would be characterized, in deciding whether to sell
  that security.

  The Equity Index Fund and the Indexed Assets of the All America Fund each
  attempt to duplicate the investment results of the S&P 500 Index. As a
  result, the Adviser anticipates that these Funds will hold investments
  generally for longer periods than actively managed funds.








                  PURCHASE, REDEMPTION AND PRICING OF SHARES


  CALCULATION OF NET ASSET VALUE
    ----------------------------------------------------------------------------
   
  An investor purchases or redeems shares of a Fund at net asset value. A Fund's
  net asset value is equal to:


    o   the sum of the value of the securities the Fund holds,

                                      -19-
<PAGE>

    o   plus any cash or other assets, including interest and dividends accrued,
        and

    o   minus all liabilities, including accrued expenses.

The net asset value of each Fund is determined once daily immediately after the
declaration of dividends, if any, and is determined as of the time of the close
of the regular trading session on the New York Stock Exchange (generally 4:00
p.m. Eastern Time) on each day during which such Exchange is open for trading.

A Fund's net asset value per share is equal to the Fund's net asset value
divided by the number of Fund shares outstanding.


PRICING OF SECURITIES HELD BY THE FUNDS
- --------------------------------------------------------------------------------
   
In determining a Fund's net asset value, the Adviser must value the securities
and other assets the Fund owns.


  1) If market quotations are readily available for an investment, the Adviser
  uses market value as follows:

    o   An equity security will be valued at the last sale price for the
        security on the principal exchange on which the security is traded, or
        at the last bid price on the principal exchange on which such security
        is traded if such bid price is of a more recent day than the last sale
        price.

    o   For any equity security not traded on an exchange but traded in the
        over-the-counter market, the value will be the last sale price
        available, or if no sale, at the latest available bid price.

    o   Debt securities will be valued at a composite fair market value,
        "evaluated bid," which may be the last sale price, by a valuation
        service selected by the Adviser and approved by the Investment Company's
        Board of Directors.

  2) If there are any portfolio securities or assets for which market
   quotations are not readily available, the Adviser will use fair value
   pricing, as determined in good faith by or under the direction of the Board
   of Directors of the Investment Company.

  3) If a money market security has a remaining maturity of 60 days or less,
   the Adviser will use the amortized cost method of valuation to approximate
   market value, as follows:

    o   A security is initially valued at cost on the date of purchase (or at
        market value on the 61st day prior to maturity if the security had more
        than 60 days remaining to maturity at date of purchase by a Fund), and
        the Adviser assumes constant proportionate amortization in value until
        maturity of any discount or premium.

    o   The maturity of a variable rate certificate of deposit is deemed to be
        the next coupon date on which the interest rate is to be adjusted.

    o   Market value will be used instead if the amortized cost value is
        materially different from the actual market value of the security.

  4) For stock options and futures contracts, these valuations apply:

    o   Stock options written by a Fund are valued at the mean of the last bid
        and asked price on the principal exchange where the option is traded, as
        of the close of trading on that exchange.

    o   When a Fund writes a call option, the amount of the premium is included
        in the Fund's assets and an amount is included in its liabilities. The
        liability thereafter is adjusted to the current market value of the
        call.


        - If a call expires or if the Fund enters into a closing purchase
          transaction, it realizes a gain (or a loss if the cost of the
          transaction exceeds the premium received when the call was written)
          without regard to any unrealized appreciation or depreciation in the
          underlying securities, and the liability related to such call is
          extinguished.

        - If a call is exercised, the Fund realizes a gain or loss from the
          sale of the underlying securities and the proceeds of the sale
          increased by the premium originally received.

    o   A premium a Fund pays on the purchase of a put will be deducted from a
        Fund's assets and an equal amount will be included as an investment and
        subsequently adjusted to the current market value of the put.


                                      -20-
<PAGE>

    o   Futures contracts, and options thereon, traded on commodities exchanges
        are valued at their official settlement price as of the close of such
        commodities exchanges.



                      TAXATION OF THE INVESTMENT COMPANY


  TAXES ON FUNDS' INVESTMENT EARNINGS AND INCOME
    ----------------------------------------------------------------------------
   
  The Investment Company has in the past elected the special tax treatment
  afforded a "regulated investment company" under Subchapter M of the Internal
  Revenue Code, and it intends to continue to qualify under Subchapter M. The
  Investment Company will not owe Federal income tax on the ordinary income
  and net realized capital gains that it distributes to shareholders, if it
  qualifies as a regulated investment company.

  If the Investment Company were to fail to qualify as a regulated investment
  company, it would be subject to Federal income tax on the Funds' ordinary
  income and net realized capital gains, whether or not it distributes the
  income and gains to shareholders. If the Funds were to pay Federal income
  tax, their investment performance would be negatively affected.

  Section 4982 of the Code imposes an excise tax of 4% on a regulated
  investment company that does not make a "required distribution" to
  shareholders of 98% of its ordinary income for each calendar year and 98% of
  its capital gain income for the one year period ending October 31 of each
  year. The Investment Company intends to make the "required distributions"
  and to thereby avoid the excise tax. If a Fund were to distribute less than
  the required amount, then the 4% excise tax would apply to the deficiency,
  wh.ich would reduce the investment performance of the Funds.


  INCOME DIVIDENDS AND CAPITAL GAINS DISTRIBUTIONS
    ----------------------------------------------------------------------------
   
  The Investment Company declares dividend distributions semi-annually (at the
  end of June and end of December) in the case of net investment income and
  annually (at the end of December) in the case of net realized short or
  long-term capital gains. A shareholder's dividend distributions are
  automatically reinvested in full or fractional shares of the Fund to which
  they relate, unless the shareholder elects on its application or an
  amendment to the application either (1) to receive dividend distributions in
  cash or, (2) in the case of distributions by the Equity Index, All America
  and Bond Funds, to purchase shares of the Money Market Fund (in which case
  the $5,000 minimum is waived).

  Cash dividend distributions are paid by wire transfer of Federal funds.
  Payment of dividends normally will be made on the first business day of the
  following month at the net asset value as of the last business day of the
  month in which the dividend distribution is declared. Dividends and other
  distributions are taxable to a Fund's shareholders even though they are
  reinvested in additional shares of the Fund.



                           TAXATION OF SHAREHOLDERS

  The discussion below provides information that may be helpful to a
  shareholder, but it is not a detailed explanation of the Federal, state or
  local income tax treatment of a shareholder. Potential purchasers of shares
  of a Fund are encouraged to consult their tax advisers regarding specific
  questions as to Federal, state or local taxes. Foreign investors should
  consider applicable foreign taxes in their evaluation of an investment in a
  Fund as well. Many of the rules set forth below do not apply to
  not-for-profit organizations and other entities that are not subject to
  Federal income taxation.

  CHARACTERIZATION OF FUNDS' DISTRIBUTIONS. Dividends paid by a Fund out of
  its ordinary income and distributions of a Fund's net realized short-term
  capital gains (jointly, the "ordinary income dividends") are taxable to its
  shareholders as ordinary income. Distributions made from a Fund's net
  realized long-term capital gains, including long-term gains from certain
  transactions in futures and options, (the "capital gain dividends") are
  taxable to the Fund's shareholders as long-term capital gain.

  PASSIVE FOREIGN INVESTMENT COMPANY ("PFIC"). Due to investment laws in
  certain foreign countries, it is anticipated that a Fund's investments in
  equity securities in such countries may consist of shares of investment
  companies (or similar investment entities) organized under foreign law or of
  ownership interests in special accounts, trusts or partnerships. If the Fund
  purchases shares of an investment company (or similar investment entity)
  organized under foreign law, the Fund will be treated as owning shares in a
  PFIC for U.S. federal income tax purposes. The Fund may be subject to U.S.
  federal income tax, and an additional tax in the nature of interest,


                                      -21-
<PAGE>

  on a portion of distributions from such company and on gain from the
  disposition of such shares (collectively referred to as "excess
  distributions"), even if such excess distributions are paid by the Fund as a
  dividend to its shareholders. The Fund may be eligible to make an election
  with respect to certain PFICs in which it owns shares that will allow it to
  avoid the taxes on excess distributions. However, such election may cause
  the Fund to recognize income in a particular year in excess of the
  distributions received from such PFICs. Alternatively, under proposed
  regulations the Fund would be able to elect to "mark to market" at the end
  of each taxable year all shares that it holds in PFICs. If it made this
  election, the Fund would recognize as ordinary income any increase in the
  value of such shares. Unrealized losses, however, would not be recognized.
  By making the mark-to-market election, the Fund could avoid imposition of
  the interest charge with respect to its distributions from PFICs, but in any
  particular year might be required to recognize income in excess of the
  distributions it received from PFICs and its proceeds from dispositions of
  PFIC stock.

  FOREIGN CURRENCY GAINS OR LOSSES. Foreign currency gains or losses from
  certain debt instruments are generally treated as ordinary income or loss.
  These gains or losses will generally increase or decrease the amount of a
  Fund's investment company taxable income available to be distributed to
  shareholders as ordinary income. Additionally, if losses of this nature
  exceed a Fund's other investment company taxable income during a taxable
  year, a Fund would not be able to make any ordinary income dividend
  distributions. Any such distribution made before the losses were realized
  (but in the same taxable year) would be recharacterized as a return of
  capital to a Fund's shareholders, thereby reducing the shareholders' basis
  in the Fund's shares, and resulting in a capital gain for any shareholder
  who received a distribution greater than that shareholder's basis in the
  Fund's shares (assuming the shares were held as capital assets).

  TAXATION OF FOREIGN COUNTRY INCOME. Dividends and interest received by a
  Fund may be subject to withholding and other taxes imposed by foreign
  countries. Tax conventions between certain countries and the United States
  may reduce or eliminate these foreign taxes. These foreign taxes will reduce
  the amount of funds available for distributions by a Fund, but are included
  in the taxable income reported by the Fund's shareholders. Since stock and
  securities of foreign issuers will account for less than 50% of the assets
  of each Fund, the Fund's shareholders will not be able to claim a credit or
  deduction for these foreign taxes paid by a Fund.

  ORIGINAL ISSUE DISCOUNT. The Funds may purchase debt securities that contain
  original issue discount. Original issue discount that accrues in a taxable
  year is treated as income earned by a Fund and is subject to the
  distribution requirements of the Internal Revenue Code. A Fund, however,
  generally will not receive any cash income for the original issue discount
  income it earns in a taxable year. Debt securities that a Fund acquires also
  may be subject to the market discount rules.

  CAPITAL GAINS RATES FOR ENTITIES OTHER THAN INDIVIDUALS. Capital gains of
  corporations are subject to tax at the same rates applicable to ordinary
  income. Capital losses may be used only to offset capital gains and excess
  net capital loss may be carried back three years and forward five years.

  DIVIDENDS RECEIVED DEDUCTIONS. Certain corporations are entitled to a 70%
  dividends received deduction for distributions from certain domestic
  corporations. The Equity Index Fund and All America Fund will designate the
  portion of any distributions that qualify for the 70% dividends received
  deduction. The amount designated may not exceed the amount received by the
  Equity Index Fund or All America Fund for its taxable year that qualifies
  for the dividends received deduction. (Since none of the income of the Bond
  Fund or the Money Market Fund is expected to be derived from dividends from
  domestic corporations, it is not anticipated that any portion of the
  ordinary income dividends of the Bond Fund or the Money Market Fund will
  qualify for the dividends received deduction.)

  STATE AND LOCAL TAXATION. In addition to Federal income taxation, ordinary
  income and capital gain dividends, along with gain from the sale of Fund
  shares, may be subject to state and local taxes. State law varies as to
  whether dividend income paid by a Fund attributable to U.S. Government
  obligations is exempt from state income tax, and a shareholder should
  consult its tax adviser with respect to this issue.

  PRIVATE FOUNDATIONS. Private foundations and their managers are subject to
  excise taxes under the Code if they invest "any amount in such a manner as
  to jeopardize the carrying out of any of the foundation's exempt purposes."
  This rule requires a foundation manager, in making an investment, to
  exercise "ordinary business care and prudence" under the facts and
  circumstances prevailing at the time of making the investment, in providing
  for the short-term and long-term needs of the foundation in carrying out its
  exempt purposes.

  The factors that a foundation manager may take into account in assessing an
  investment under this standard include the expected rate of return (both
  income and capital appreciation), the risks of rising and falling price
  levels, and the need for diversification within the foundation's portfolio.
  A substantial percentage of investments


                                      -22-
<PAGE>

  of certain "private operating foundations", as defined in the Code, may be
  restricted to assets directly devoted to their tax-exempt purposes. Each
  manager of a private foundation should consult the manager's and the
  foundation's tax advisers regarding the foregoing considerations.

  ENDOWMENT FUNDS. Investment managers of endowment funds should consider
  whether the acquisition by such funds of shares in the Funds is legally
  permissible. This is not a matter of federal law, but is determined under
  applicable state statutes. It should be noted, however, that under the
  Uniform Management of Institutional Funds Act, which has been adopted in
  various forms by a large number of states, participation in mutual funds or
  similar organizations, in which funds are commingled and investment
  determinations are made by persons other than the governing board of the
  endowment fund, is permitted. Each investment manager of an endowment fund
  should consult the endowment fund's counsel regarding the foregoing
  considerations.

  RETIREMENT TRUSTS, INCLUDING QUALIFIED PLANS. The Funds may accept
  investments from tax-qualified pension, profit-sharing or stock bonus plans,
  governmental plans and units, and Taft-Hartley plans (all such entities
  hereinafter being referred to as "Retirement Trusts"). A fiduciary of a
  Retirement Trust other than a governmental plan or unit (a "Qualified Plan")
  is subject to certain requirements under the Employee Retirement Income
  Security Act of 1974, as amended ("ERISA"), including the discharge of
  duties solely in the interest of, and for the exclusive purpose of providing
  benefits to, the Qualified Plan's participants and beneficiaries.

  In considering an investment in the Funds of a portion of the assets of any
  Qualified Plan, a fiduciary should consider, among other factors: (a)
  whether the investment is permitted by the documents and instruments
  governing the Qualified Plan; (b) whether the investment satisfies the
  diversification requirements of Section 404(a)(1)(C) of ERISA, if
  applicable; (c) whether the investment provides sufficient liquidity to
  permit benefit payments to be made as they become due; (d) whether the
  investment is for the exclusive purpose of providing benefits to
  participants and their beneficiaries; and (e) whether the investment may
  constitute a "prohibited transaction" (within the meaning of Section 406 of
  ERISA and Section 4975(c) of the Code). Each fiduciary of a Qualified Plan
  (and any other person subject to ERISA) should consult such person's tax or
  other advisers regarding the foregoing considerations.


     SHAREHOLDER WITHHOLDING

  The Investment Company may be required to withhold for Federal income tax
  ("back-up withholding") from distributions made and the proceeds of
  redemptions to a shareholder who is not exempt from back-up withholding,
  because the shareholder has not provided a correct taxpayer identification
  number or made required certifications, or when the Investment Company or
  the shareholder has been notified by the Internal Revenue Service that the
  shareholder is subject to back-up withholding.

  Ordinary income dividends paid by a Fund to a shareholder that is a
  nonresident alien or a foreign entity will be subject to a 30% U.S.
  withholding tax applicable to foreign persons, unless a reduced rate of
  withholding or a withholding exemption is provided under applicable law or
  an applicable tax convention between the United States and a particular
  foreign country. Foreign shareholders are urged to consult their own tax
  advisers concerning the applicability of the U.S. withholding tax.



                       YIELD AND PERFORMANCE INFORMATION

  Performance information is computed separately for each Fund in accordance
  with the formulas described below. At any time in the future, total return
  and yields may be higher or lower than in the past and there can be no
  assurance that any historical results will continue.

  YIELD OF THE MONEY MARKET FUND. The Money Market Fund calculates a seven-day
  "current yield" (eight days when the seventh prior day has no net asset
  value because the Investment Company is closed on that day) based on a
  hypothetical shareholder account containing one share at the beginning of
  the seven-day period. The return is calculated for the period by determining
  the net change in the hypothetical account's value for the period, excluding
  capital changes. The net change is divided by the share value at the
  beginning of the period to give the base period return. This base period
  return is then multiplied by 365/7 to annualize the yield figure, which is
  carried to the nearest one-hundredth of one percent.

  Realized capital gains or losses and unrealized appreciation or depreciation
  of the assets of the Money Market Fund are included in the hypothetical
  account for the beginning of the period but changes during the period are
  not included in the value for the end of the period. Values also reflect
  asset charges (for advisory fees) as well as brokerage fees and other
  expenses.

  Current yields will fluctuate daily. Accordingly, yields for any given
  seven-day period do not necessarily represent future results. It should be
  remembered that yield depends on the type, quality, maturities and rates of
  return of the Money Market Fund's investments, among other factors. The
  Money Market Fund yield does not reflect the cost of insurance and other
  insurance company separate account charges. It also should not be compared
  to the yield of money market funds made available to the general public
  because they may use a different method to calculate yield. In addition,
  their yields are usually calculated on the basis of a constant one dollar
  price per share and they pay out earnings and dividends which accrue on a
  daily basis.

  The following is an example of the calculation of the Money Market Fund's
  yield for the seven-day period ended December 31, 1998. Yields may fluctuate
  substantially from the example shown. 

  1. Value for December 22, 1998

  2. Value for December 29, 1998 (exclusive of capital changes)

  3. Net change equals Line 1 subtracted from Line 2

  4. Base period return equals Line 3 divided by Line 1

  5. Current yield equals Line 4 annualized (multiplied by 365/7)

  The Money Market Fund calculates effective yield by following Steps 1 - 4
  above to obtain a base period return, then compounding the base period
  return as follows:

             Effective Yield = [(Base Period Return + 1) 365/7] - 1

  CALCULATION OF TOTAL RETURN AND AVERAGE ANNUAL TOTAL RETURN. Total Return
  with respect to the shares of a Fund is a measure of the change in value of
  an investment in a Fund over the period covered, which assumes that any
  dividends or capital gains distributions are reinvested in that Fund's
  shares immediately rather than paid to the investor in cash.

     The formula for Total Return with respect to a Fund's shares used herein
includes four steps:

  (1) adding to the total number of shares purchased by a hypothetical $1,000
      investment the number of shares which would have been purchased if all
      dividends and distributions paid or distributed during the period had been
      immediately reinvested;

  (2) calculating the value of the hypothetical initial investment of $1,000 as
      of the end of the period by multiplying the total number of shares on the
      last trading day of the period by the net asset value per share on the
      last trading day of the period;

  (3) assuming redemption at the end of the period; and

  (4) dividing this account value for the hypothetical investor by the initial
      $1,000 investment. Average Annual Total Return is measured by annualizing
      Total Return over the period.


                          AVERAGE ANNUAL TOTAL RETURN

  YIELD OF THE BOND FUND. Yield of the shares of the Bond Fund will be
  computed by annualizing net investment income, as determined by the
  Commission's formula, calculated on a per share basis, for a recent
  one-month or 30-day period and dividing that amount by the net asset value
  per share of the Fund on the last trading day of that period. Net investment
  income will reflect amortization of any market value premium or discount of
  fixed income securities (except for obligations backed by mortgages or other
  assets) over such period and may include recognition of a pro rata portion
  of the stated dividend rate of dividend paying portfolio securities. The
  Yield of the Fund will vary from time to time depending upon market
  conditions, the composition of the portfolio and operating expenses
  allocated to the Fund.

  PERFORMANCE COMPARISONS. Each Fund may from time to time include the Total
  Return, the Average Annual Total Return and Yield of its shares in
  advertisements or in information furnished to shareholders. The Money Market
  Fund may also from time to time include the Yield and Effective Yield of its
  shares in information furnished to shareholders.

  Each Fund may from time to time also include the ranking of its performance
  figures relative to such figures for groups of mutual funds categorized by
  Lipper Analytical Services ("Lipper") as having the same or similar
  investment objectives or by similar services that monitor the performance of
  mutual funds. Each Fund may also from time to time compare its performance
  to average mutual fund performance figures compiled by Lipper in Lipper
  Performance Analysis.

  Advertisements or information the Investment Company furnishes to current or
  prospective investors also may include evaluations of a Fund published by
  nationally recognized ranking services and by financial publications that
  are nationally recognized. These publications may include BARRON'S, BUSINESS
  WEEK, CDA TECHNOLOGIES, INC., CHANGING TIMES, DOW JONES INDUSTRIAL AVERAGE,
  FINANCIAL PLANNING, FINANCIAL WORLD, FORBES, FORTUNE, HULBERT'S FINANCIAL
  DIGEST, INSTITUTIONAL INVESTOR, INVESTORS DAILY, MONEY, MORNINGSTAR MUTUAL
  FUNDS, THE NEW YORK TIMES, STANGER'S INVESTMENT ADVISER, VALUE LINE, THE
  WALL STREET JOURNAL, WIESENBERGER INVESTMENT COMPANY SERVICE and USA TODAY.

  In reports or other communications to shareholders, the Investment Company
  also may describe general economic and market conditions affecting the Funds
  and may compare the performance of the Funds with (1) that of mutual funds
  included in the rankings prepared by Lipper or similar investment services
  that monitor the performance of insurance company separate accounts or
  mutual funds, (2) IBC/Donoghue's Money Fund Report, (3) other appropriate
  indices of investment securities and averages for peer universe of funds
  which are described in this Statement of Additional Information, or (4) data
  developed by the Adviser or any of the Subadvisers derived from such indices
  or averages.


  COMPARATIVE INDICES FOR THE FUNDS
    ----------------------------------------------------------------------------
   
  The Investment Company compares the performance of each Fund (other than the
  Money Market Fund) against a widely recognized index or indices for stock or
  bond market performance, based on the type of securities the Fund purchases.
  The annual and semi-annual financial reports that the Investment Company
  prepares will contain graphs with the Funds' performances compared to their
  indices.

  It is not possible for an investor to directly invest in an unmanaged index.
  Performance comparisons to indices are for informational purposes and do not
  reflect any actual investment. The Funds pay investment advisory and other
  expenses that are not applicable to unmanaged indices.

  EQUITY INDEX FUND AND ALL AMERICA FUND: Performance of each of these Funds
  is compared to the Standard & Poor's Composite Index of 500 Stocks (the "S&P
  500 Index").

  The S&P 500 Index is a market value-weighted and unmanaged index showing the
  changes in the aggregate market value of 500 stocks relative to the base
  period 1941-43. The S&P 500 Index is composed almost entirely of common
  stocks of companies listed on the NYSE, although the common stocks of a few
  companies listed on the American Stock Exchange or traded OTC are included.
  The 500 companies represented include approximately 400 industrial concerns,
  as well as financial services, utility and transportation concerns. The S&P
  500 Index represents about 80% of the market value of all issues traded on
  the NYSE.

  BOND FUND: Performance is compared to the Lehman Brothers
  Government/Corporate Bond Index (the "Lehman Government/Corporate Index").


                                      -25-
<PAGE>

  The Lehman Government/Corporate Index is a measure of the market value of
  approximately 5,300 bonds with a face value currently in excess of $1
  million, which have at least one year to maturity and are rated "Baa" or
  higher ("investment grade") by a nationally recognized statistical rating
  agency.



                     DESCRIPTION OF CORPORATE BOND RATINGS

     Description of Corporate bond ratings of 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.

  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 mid-range ranking; and
  the modifier 3 indicates that the issue ranks in the lower end of its
  generic rating category.

     Description of corporate bond ratings of Standard & Poor's Corporation:

  AAA - Debt rated AAA has the highest rating assigned by Standard & Poor's.
       Capacity to pay interest and repay principal is very strong.

  AA  - Debt rated AA has a very strong capacity to pay interest and repay
       principal and differs from the higher rated issues only in small degree.
        

  A   - Debt rated A has a strong capacity to pay interest and repay
       principal, although it is somewhat more susceptible to the adverse
       effects of changes in circumstances and economic conditions than debt in
       higher rated categories.


                                      -26-
<PAGE>

  BBB - Debt rated BBB is regarded as having an adequate capacity to pay
       interest and repay principal. Whereas it normally exhibits adequate
       protection parameters, adverse economic conditions or changing
       circumstances are more likely to lead to a weakened capacity to pay
       interest and repay principal for debt in this category than in
       higher-rated categories.

  BB-B-CCC-CC-Debt rated BB, B, CCC and CC is 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 debt 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.

  Plus (+) or Minus (-): The ratings from "AA" to "BB" may be modified by the
  addition of a plus or minus sign to show relative standing within the major
  rating categories.

ITEM 26. NUMBER OF HOLDERS OF SECURITIES

     As of January 31, 1999, there were   record owners of securities
registered pursuant to this Registration Statement.


ITEM 27. INDEMNIFICATION

     ARTICLES OF INCORPORATION OF THE FUND. The Articles of Incorporation of
the Fund provide in substance that no director or officer of the Fund shall be
liable to the Fund or its shareholders for money damages, unless the director
or officer is subject to liability by reason of willful misfeasance, bad faith,
gross negligence or reckless disregard of duties in the conduct of his or her
office.

     BY-LAWS OF THE FUND. The By-Laws of the Fund provide for the
indemnification of present and former officers and directors of the Fund
against liability by reason of service to the Fund, unless the officer or
director is subject to liability by reason of willful misfeasance, bad faith,
gross negligence or reckless disregard of the duties involved in the conduct of
his or her office (Disabling Conduct). No indemnification shall be made to an
officer or director unless there has been a final adjudication on the merits, a
dismissal of a proceeding for insufficiency of evidence of Disabling Conduct,
or a reasonable determination has been made that no Disabling Conduct occurred.
The Fund may advance payment of expenses only if the officer or director to be
indemnified undertakes to repay the advance unless indemnification is made and
if one of the following applies: the officer of director provides a security
for his or her undertaking, the Fund is insured against losses from any lawful
advances, or a reasonable determination has been made that there is reason to
believe the officer or director ultimately will be entitled to indemnification.
 

     INSURANCE. Coverage for officers and director of the Adviser, Distributor
and the Fund is provided under an Investment Management insurance policy issued
by American International Specialty Lines Insurance Company, with excess
coverage by Chubb custom Insurance Company, to Mutual of America Life Insurance
Company et al. The aggregate limit of liability under the policy per year is
$10 million, with a $200,000 deductible per entity insured and a $1,000
deductible for individual insureds.

     BY-LAWS OF THE ADVISER. The By-Laws of Mutual of America Capital
Management Corporation, the Fund's Adviser, provide for the indemnification by
the Corporation of present and former directors and officers of the Corporation
and of any organization for which service is rendered at the request of the
Corporation and permits the advance payment of expenses in certain
circumstances for covered persons in connection with suits by third parties and
derivative suits. Each covered person must have acted in good faith and in a
manner the person reasonably believed to be in or not opposed to the best
interests of the Corporation and, with respect to any criminal action or
proceeding, had no reasonable cause to believe the conduct was unlawful. If in
connection with a derivative suit a covered person shall have been adjudged to
be liable to the Corporation, indemnification shall not be made unless and only
to the extent that the Delaware Court of Chancery or the court in which such
action or suit was brought shall determine upon application that, despite the
adjudication of liability but in view of all the circumstances of the case,
such person is entitled to indemnity. Thus, the officers and directors of the
fund and the Adviser are indemnified by the Adviser for their services in
connection with the Fund to the extent set forth in the By-Laws.

     BY-LAWS OF THE DISTRIBUTOR. The By-laws of Mutual of America Securities
Corporation, the principal underwriter and distributor for the fund, provide
for the indemnification by the Corporation of present and former directors and
officers of the Corporation and of any organization for which service is
rendered at the request of the Corporation and permits the advance payment of
expenses in certain circumstances for covered persons in connection with suits
by third parties and derivative suits. Each covered person must have acted in
good faith and in a manner the person reasonably believed to be in or not
opposed to the best interests of the Corporation and, with respect to any
criminal action or proceeding, had no reasonable cause to believe the conduct
was unlawful. If in connection with a derivative suit a covered person shall
have been adjudged to be liable to the Corporation, indemnification shall not
be made unless and only to the extent that the


                                      C-2
<PAGE>

Delaware Court of Chancery or the court in which such action or suit was
brought shall determine upon application that, despite the adjudication of
liability but in view of all the circumstances of the case, such person is
entitled to indemnity. Thus, the officers and directors of the Distributor are
indemnified by the Distributor for their services in connection with the Fund
to the extent set forth in the By-Laws.

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


ITEM 28. BUSINESS AND OTHER CONNECTIONS OF INVESTMENT ADVISERS

     Mutual of America Capital Management corporation (the Adviser) is the
investment adviser to the Fund and is registered as an investment adviser under

                          INVESTMENT ADVISORY AGREEMENT


      INVESTMENT ADVISORY AGREEMENT, made the 1st day of May, 1996, as amended
May 1, 1997 with respect to the Money Market Fund and May 1, 1999 with respect
to the Equity Index Fund, by and between Mutual of America Capital Management
Corporation (the "Adviser"), a Delaware corporation, and Mutual of America
Institutional Funds, Inc. (the "Company"), a Maryland corporation.

                               W I T N E S S E T H

      WHEREAS, the Company is engaged in business as a diversified open-end
management investment company and is registered as such under the Investment
Company Act of 1940, as amended (the "Investment Company Act");

      WHEREAS, the Company is comprised of separate series or funds, each of
which pursues its investment objective through separate investment policies, and
the Board of Directors may from time to time establish or terminate one or more
funds;

      WHEREAS, the Adviser renders advisory services and is registered as an
investment adviser under the Investment Advisers Act of 1940; and

      WHEREAS, the Company desires to retain the Adviser to render investment
advisory and supervisory services and corporate administration to the Company in
the manner and on the terms hereinafter set forth;

      NOW THEREFORE, in consideration of the premises and the mutual agreements
herein contained, the Adviser and the Company agree as follows:

1.    General. For the period and on the terms set forth in this Agreement, the
Adviser shall manage the investment and reinvestment of the assets of the
existing funds of the Company, namely the All America Fund and the Bond Fund,
and of any additional funds created in the future (collectively, the existing
and any additional funds are hereinafter referred to as "Funds"). The Adviser
agrees during such period, at its own expense and subject to the supervision of
the Board of Directors of the Company, to render the investment advisory
services and assume the obligations herein set forth, for the compensation
provided by this Agreement.

      The Adviser is authorized to enter into sub-advisory agreements (each a
"Sub-Advisory Agreement" and collectively the "Sub-Advisory Agreements") with
registered investment advisers (each a "Sub-Adviser" and collectively the
"Sub-Advisers") pursuant to which the Adviser delegates to the Sub-Advisers its
obligations for providing investment advisory and certain other services in
connection with one or more of the Funds; provided, that the Adviser, and not
the Company, shall be responsible for any compensation payable under the
Sub-Advisory Agreements. Any such Sub-Advisory Agreement may be entered into by
the Adviser on such terms and in such manner as may be permitted by the
Investment Company Act and the

<PAGE>

                                      -2-

rules and regulations thereunder. For any Fund for which the Adviser has entered
into a Sub-Advisory Agreement, the Sub-Adviser shall have the primary
responsibility for providing investment advisory services as set forth in
Paragraph 2(a),(b) and (c) and shall be responsible for broker-dealer selection
as set forth in Paragraph 4 and maintaining books and records as set forth in
Paragraph 9, and the Adviser will have supervisory responsibility for investment
advisory services furnished by the Sub-Adviser pursuant to the Sub-Advisory
Agreement. The Adviser will review the performance of each Sub-Adviser and make
recommendations to the Board of Directors of the Company with respect to the
retention and renewal of Sub-Advisory Agreements.

2.    Investment Advisory Services. (a) In carrying out its obligations to
manage the investment and reinvestment of the assets of the Company, the Adviser
shall as appropriate and consistent with the limitations set forth in Paragraph
3 hereof:

   (i)   perform research and obtain and evaluate pertinent economic,
         statistical and financial data relevant to the investment policies of
         each of the Funds as set forth in the then effective registration
         statement for the Company, as amended from time to time ("Registration
         Statement"), filed with the Securities and Exchange Commission (the
         "SEC");

   (ii)  consult with the Board of Directors of the Company and furnish to the
         Board of Directors of the Company recommendations with respect to an
         overall investment plan for each of the Funds for approval,
         modification or rejection by the Board of Directors of the Company;

   (iii) determine the composition of the assets of each Fund and implement
         specific investment and sale opportunities, consistent with any overall
         investment plans approved by the Board of Directors of the Company;

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

   (v)   regularly report to the Board of Directors of the Company with respect
         to the implementation of any approved overall investment plans and any
         other activities in connection with management of the assets of the
         Company; and

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

      (b) In connection with the purchase and sale of securities for each Fund,
the Adviser will arrange for the transmission to the custodian, transfer agent,
dividend disbursing agent and/or recordkeeping agent for the Fund (such
custodian and agent or agents hereinafter referred

<PAGE>
                                      -3-

to as the "Agent" or collectively the "Agents"), on a daily basis, such
confirmations, trade tickets (which shall state industry classifications unless
the Adviser has previously furnished a list of classifications for portfolio
securities), and other documents and information, including, but not limited to,
Cusip or other numbers that identify securities to be purchased or sold on
behalf of each Fund and, with respect to mortgage derivative and asset-backed
securities purchased by the Adviser for a Fund, 1066Q reports and supplemental
information as required to be available pursuant to Internal Revenue Service
requirements, as may be reasonably necessary to enable the Agent to perform its
administrative and recordkeeping responsibilities with respect to such Fund.
With respect to portfolio securities to be purchased or sold through the
Depository Trust Company, the Adviser will arrange for the automatic
transmission of the confirmation of such trades to the Company's Agent.

      (c) If the Company has arranged for the valuation of Fund securities to be
performed by an Agent, the Adviser will monitor on a daily basis, by review of
daily pricing reports provided by the Agent to the Adviser, the determination by
the Agent of the valuation of portfolio securities and other investments of each
Fund. The Adviser shall not be obligated to independently verify the Agent's
pricing determinations, and the Agent's responsibility for accurate pricing
determinations of the value of each Fund's securities shall not be reduced by
the Adviser's duty to monitor such determinations. The Adviser will assist the
Agent in determining or confirming, consistent with the procedures and policies
stated in the Registration Statement, the value of any portfolio securities or
other assets of each Fund for which the Agent seeks assistance from or
identifies for review by the Adviser.

      d) The Adviser shall provide all the office space, facilities, equipment,
material and personnel necessary to fulfill its obligations under this Agreement
and shall provide management services to the Company as follows:

   (i)   coordinate all matters relating to the functions of the Company's
         Agents, accountants, attorneys, Sub-Advisers, if any, and other parties
         performing services or operational functions for the Funds;

   (ii)  provide, without remuneration from or other cost to the Company, the
         services of a sufficient number of individuals competent to perform all
         of the Company's executive, administrative and clerical functions as
         are necessary to ensure compliance with federal securities laws as well
         as other applicable laws and to provide effective supervision and
         administration of the Company, when such services are not performed by
         employees or other agents engaged by the Company pursuant to a separate
         agreement or arrangement with the Company;

   (iii) assist in the preparation of all periodic reports to the shareholders
         of the Company and all reports and filings required to maintain the
         registration and qualification of the Company's shares, or to meet
         other regulatory or tax requirements applicable to the Company, under
         federal and state securities and tax laws;


<PAGE>

                                      -4-

       (iv) prepare and, after approval by the Company, file and arrange for the
            distribution of proxy materials and periodic reports to Company
            shareholders as required by applicable law;

       (v)  prepare, or cause the preparation of, and, after approval by the
            Company, arrange for the filing of such registration statements and
            other documents with the SEC and other federal and state regulatory
            authorities as may be required by applicable law; and

       (vi) take such other action with respect to the Funds, after approval by
            the Company, as may be required by applicable law, including without
            limitation the rules and regulations of the SEC and of state
            securities commissions and other regulatory agencies.

3.     Limitations on Advisory Services. The Adviser shall render investment
advisory services with respect to assets held by the Funds of the Company and
effect all purchases and sales of investments for each Fund thereof in a manner
consistent with:

      (a) the investment objectives, policies and restrictions for each Fund as
stated in the Registration Statement;

      (b)  the Rules and Regulations of the Company;

      (c) the provisions of the Investment Company Act and the rules and
regulations thereunder; and

      (d) the qualification of each Fund as a regulated investment company under
Subchapter M of the Internal Revenue Code of 1986, as amended.

      Any investment program undertaken by the Adviser pursuant to this
Agreement shall at all times be subject to any directives of the Board of
Directors of the Company or any duly constituted committee thereof acting
pursuant to like authority.

4.     Brokerage and Research Services. The Adviser shall, subject to the
supervision of the Board of Directors of the Company, arrange for the placement
of orders for each of the Funds, either directly with the issuer, with any
broker-dealer or underwriter that specializes in the securities for which the
order is made, or with any other broker or dealer selected by the Adviser,
subject to the following limitations.

      The Adviser is authorized to select the brokers or dealers that will
execute the purchases and sales of portfolio securities for the Funds and will
use its best efforts to obtain the most favorable net results, taking into
account all appropriate factors, including price, dealer spread or commission,
if any, size of the transaction and difficulty of execution. However, in
addition to seeking the best price and execution, the Adviser may also take into
consideration research and statistical information and wire and other quotation
services provided to the Adviser. In any

<PAGE>
                                      -5-

event, the Adviser shall select only brokers whose commissions it believes are
reasonable. The Adviser will periodically evaluate the statistical data,
research and other investment services provided by brokers and dealers to it.
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
activities or investment operations. In accordance with Section 11(a) of the
Securities Exchange Act of 1934 and Rule 11a2-2('I') thereunder, and subject to
any other applicable laws and regulations including Section 17(e) of the
Investment Company Act and Rule 17e-1 thereunder, the Adviser may engage its
affiliates, or any Sub-Adviser to the Company and its respective affiliates, as
broker-dealers or futures commission merchants to effect portfolio transactions
in securities and other investments for a Fund.

5.     Compensation. As compensation for its investment advisory services to the
Company, the Adviser shall receive an amount calculated as a daily charge at the
annual rate of 0.125% of the value of the net assets of the Equity Index Fund,
0.50% of the value of the net assets of the All America Fund, 0.45% of the value
of the net assets of the Bond Fund and 0.20% of the value of the net assets of
the Money Market Fund, computed in accordance with the Investment Company Act
and the Registration Statement.

6.     Expenses. (a) The Adviser shall be responsible for all expenses incurred
in performing the investment advisory and management services herein set forth
(other than costs and expenses payable by any Sub-Adviser under a Subadvisory
Agreement), including costs of compensating and furnishing office space for
officers and employees of the Adviser connected with investment and economic
research, trading and investment management for the Funds and expenses of all
Company personnel other than the fees and expenses of directors who are not
"interested persons" of the Company.

      (b) Each Fund is responsible for and bears all expenses incurred in its
operation that are not specifically assumed by the Adviser or by Mutual of
America Securities Corporation pursuant to its Distribution Agreement with the
Company. General expenses of the Company not readily identifiable as belonging
to one of the Funds will be allocated among the Funds by or under the direction
of the Company's Board of Directors in such manner as the Board shall determine
to be fair and equitable. Expenses borne by each Fund include, but are not
limited to, the following (or the Fund's allocated share of the following):

   (i)   the cost (including brokerage commissions, if any) of securities
         purchased or sold by the Fund and any losses incurred in connection
         therewith;

   (ii)  investment advisory fees due hereunder (but not Sub-Advisory fees,
         which are payable by the Adviser);

   (iii) filing fees and expenses relating to the registration and qualification
         of the Company or the shares of a Fund under federal or state
         securities laws and maintenance of such registration and
         qualifications;

<PAGE>

                                      -6-

   (iv)  fees and expenses payable to the Company's Directors who are not
         "interested persons" of the Company;

   (v)   taxes (including any transfer, income or franchise taxes) and
         governmental fees;

   (vi)  costs of any liability, directors' and officers', uncollectible items
         of deposit and other insurance and of fidelity bonds;

   (vii) legal, accounting and auditing expenses;

   (viii)charges of custodians, transfer agents, recordkeeping and other
         agents;

   (ix)  expenses of setting in type and providing to the distributor of the
         Fund's shares a camera-ready copy of the Company's prospectuses,
         statements of additional information, and supplements thereto, and
         expenses of setting in type and printing or otherwise reproducing
         prospectuses, statements of additional information, supplements
         thereto, and reports and proxy materials for existing shareholders;

   (x)   fees, voluntary assessments and other expenses incurred in connection
         with membership in investment company organizations;

   (xi)  costs of meetings of shareholders; and

   (xii) extraordinary expenses.

      (c) In the event the expenses of the Company for any fiscal year
(including the fees payable to the Adviser but excluding interest, taxes,
brokerage commissions and litigation and indemnification expenses and other
extraordinary expenses not incurred in the ordinary course of the Company's
business) exceed the lowest applicable annual expense limitation established and
enforced pursuant to the statute or regulations of any applicable jurisdictions,
the compensation due the Adviser hereunder will be reduced by the amount of such
excess. If such excess amount exceeds the compensation payable to the Adviser
hereunder, the Adviser will not be required to make any additional payments to
the Company in reimbursement of such expenses.

7.     Services Not Exclusive. The services rendered by the Adviser pursuant to
this Agreement are not to be deemed exclusive, and the Adviser may render
similar services to other entities so long as its services under this Agreement
are not impaired or interfered with.

      It is understood that the Adviser or its affiliates may use any investment
research obtained for the benefit of the Company in providing investment advice
to its other investment advisory accounts or for use in managing their own
accounts. Conversely, such supplemental information obtained by the placement of
business for the Company or other entities advised by the Adviser may be
considered by and may be useful to the Adviser in carrying out its obligations
to the Company.
<PAGE>
                                      -7-

      When the Adviser deems the purchase or sale of a security to be in the
best interests of a Fund 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 such Fund 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 the Adviser in the manner it considers to be most
equitable and consistent with its fiduciary obligations to the Company and to
such other accounts or companies. The Company recognizes that in some cases this
procedure may adversely affect the size of the position obtainable for it.

8.     Term of Agreement. This Agreement will continue for two years from the
date of its execution and thereafter from year to year but only so long as such
continuance is specifically approved with respect to each Fund at least annually
either (i) by the Board of Directors of the Company or (ii) by a vote of a
majority of the outstanding voting securities of the Fund, provided that in
either event such continuance will also be approved by the vote of a majority of
the directors who are not interested persons (as defined in the Investment
Company Act) of the Company, cast in person at a meeting called for the purpose
of voting on such approval. In connection with such approvals, the Board of
Directors of the Company shall request and evaluate, and the Adviser shall
furnish, such information as may be reasonably necessary to evaluate the terms
of this Agreement. This Agreement:

      (a) shall not be terminated by the Adviser without the prior approval of a
new investment advisory agreement by vote of a majority of the outstanding
shares of each Fund of the Company;

      (b) shall be subject to termination, without the payment of any penalty,
by the Board of Directors of the Company, or by vote of a majority of the
outstanding shares of the Company, or with respect to a particular Fund by vote
of a majority of the outstanding shares of that Fund, in each case on sixty
days' written notice to the Adviser;

      (c) shall not be amended without specific approval of such amendment by
(i) the Board of Directors of the Company, or by the vote of a majority of the
outstanding shares of each Fund affected by such amendment, and (ii) a majority
of those members of the Board of Directors of the Company who are not parties to
this Agreement or interested persons of such a party, cast in person at a
meeting called for the purpose of voting on such approval; and

      (d) shall automatically terminate upon assignment (as defined under the
Investment Company Act) by either party.

9.     Recordkeeping. The Adviser shall keep the Company's books and records
required to be maintained by it pursuant to this Agreement, the Investment
Company Act or otherwise. The Adviser agrees that all accounts and records that
it maintains for the Company shall be the property of the Company and that it
will surrender promptly to the designated officers of the Company any or all
such accounts and records upon request. The Adviser further agrees to preserve
for the period prescribed by the rules and regulations of the SEC all such
records and

<PAGE>
                                      -8-

accounts as are required to be maintained pursuant to said rules and
regulations. The Adviser also agrees that it will maintain all records and
accounts regarding the investment activities of each of the Funds in a
confidential manner. All such accounts or records shall be made available,
within five (5) business days of a written request, to the Company's accountants
or auditors during regular business hours at the Adviser's offices. In addition,
the Adviser will provide any materials as are required to be maintained pursuant
to said rules and regulations. The Adviser also agrees that it will maintain all
records and accounts reasonably related to the investment advisory services
provided hereunder, as may reasonably be requested in writing by the members of
the Board of Directors of the Company or as may be required by any governmental
agency having jurisdiction over the Adviser or the Company.

10.    Interested and Affiliated Persons. It is understood that members,
officers, employees or agents of the Company may also be interested in the
Adviser as directors, officers, employees, agents or otherwise.

11.    Liability of the Adviser. In the absence of willful misfeasance, bad
faith, gross negligence or reckless disregard of obligations or duties on the
part of the Adviser (or its officers, directors, agents, employees, controlling
persons, and any other person or entity affiliated with the Adviser or retained
by it to perform or assist in the performance of its obligations under this
Agreement), neither the Adviser nor any of its officers, directors, employees or
agents shall be subject to liability to the Company or any shareholder of the
Company for any act or omission in the course of, or connected with, rendering
services hereunder, including without limitation, any error of judgment or
mistake of law or for any loss suffered by the Company or any shareholder of the
Company in connection with the matters to which this Agreement relates, except
to the extent specified in Section 36(b) of the Investment Company Act
concerning loss resulting from a breach of fiduciary duty with respect to the
receipt of compensation for services.

12.    Use of Name "Mutual of America"; Marks or Symbols. If the Adviser ceases
to act as the investment adviser, or, in any event, if the Adviser so requests
in writing, the Company agrees it will take all necessary action to change the
name of the Company to a name not including the words "Mutual of America". The
Adviser may from time to time make available without charge to the Company for
its use such marks or symbols owned or employed by the Adviser including marks
or symbols containing the name "Mutual of America" or any variation thereof, as
it may consider appropriate. Any such marks or symbols so made available will
remain the Adviser's property and it shall have the right, upon notice in
writing to, require the Company to cease the use of such marks or symbols at any
time.

13.    Governing Law. This Agreement is subject to the provisions of the
Investment Company Act, as amended, and the rules and regulations of the SEC
thereunder, including such exemptions therefrom as the SEC may grant. Words and
phrases used herein shall be interpreted in accordance with that Act and those
rules and regulations, and such exemptions. Without limiting the generality of
the foregoing, (a) the term "assignment" shall not include any transaction
exempted from Section 15(a)(4) of the Investment Company Act by an order of the
SEC, and (b) as used with respect to the Company or any of its Funds, the term
"majority of the outstanding

<PAGE>
                                      -9-
shares" means the lesser of (i) 67% of the shares represented at a meeting at
which more than 50% of the outstanding shares are represented, or (ii) more than
50% of the outstanding shares.

14.    Miscellaneous. The Adviser shall submit to all regulatory and
administrative bodies having jurisdiction over the operations of the Adviser or
the Company, present or future, any materials, reasonably related to the
investment advisory services provided hereunder, as may be reasonably requested
in writing by the Board of Directors of the Company or as may be required by any
governmental agency having jurisdiction.


    IN WITNESS WHEREOF, the parties hereto have caused this Investment Advisory
Agreement to be signed by their duly authorized officers as of the date first
above written.
