 ABOUT THE FUNDS                                        1


 TRANSACTION AND FUND EXPENSES
 ----------------------------------------------------------
 
   o Like all T. Rowe Price funds, these funds are 100% no load.
 
   These tables should help you understand the kinds of expenses you will bear
   indirectly as a Spectrum Fund shareholder. While the Spectrum Funds
   themselves impose no fees or charges, they will indirectly bear their
   pro-rata share of the expenses of the underlying funds in which they invest.
   Since each Spectrum Fund's returns are net of these expenses, the end result
   to the shareholder is very much the same as if the fund had an explicit
   expense ratio.
 
   Note: The funds charge a $5 fee for wire redemptions under $5,000, subject to
   change without notice, and a $10 fee is charged for small accounts when
   applicable (see Small Account Fee under Transaction Procedures and Special
   Requirements).
 
   
   Table 1 provides the range of average weighted expense ratios for each
   Spectrum Fund. A range is given instead of a single number because the
   pro-rata share of expenses fluctuates along with changes in the average
   assets invested in each of the underlying funds. For further information on
   expense ratios and management fees of the underlying funds, please refer to
   the Statement of Additional Information.

 FINANCIAL HIGHLIGHTS
 ----------------------------------------------------------
   
   Table 3, which provides information about each fund's financial history, is
   based on a single share outstanding throughout each fiscal year. Each fund's
   section of the table is part of the financial statements, which are included
   in its annual report and are incorporated by reference into the Statement of
   Additional Information (available upon request). The financial statements in
   each fund's annual report were audited by Price Waterhouse LLP, the funds'
   independent accountants.

   takes a closer look at their investment objectives and approaches.
 
 
   o The fund or funds you select should not represent your complete investment
     program nor be used for short-term trading purposes.
 
 
 What are the Spectrum Funds' objectives?
 
  . The objective of Spectrum Income Fund is a high level of current income with
   moderate share price fluctuation.
 
   
  . Spectrum Growth Fund seeks long-term capital appreciation and growth of
   income, with current income a secondary objective.
 
  . Spectrum International Fund's objective is long-term capital appreciation.
    
 
 
 What are the Spectrum Funds' investment programs?
 
   
  . Spectrum Income Fund will allocate its assets among a diversified group of
   underlying T. Rowe Price funds that invest primarily in fixed income
   securities, but may invest up to 25% in an income-oriented stock fund.
 
  . Spectrum Growth Fund will allocate its assets among a diversified group of
   eight underlying T. Rowe Price domestic stock funds and one international
   stock fund.
 
  . Spectrum International Fund allocates its assets among a group of underlying
   T. Rowe Price funds that invest primarily in international stocks and, to a
   lesser degree, international bonds.    
 
   Each Spectrum Fund will diversify within set limits based on the managers'
   outlook for the domestic and international economies, financial markets, and
   relative market valuations of each underlying fund and, in the case of
   Spectrum International Fund, additional factors inherent in international
   investing.
 
   
   The underlying funds in which each Spectrum Fund may invest and the
   percentage of total assets they may allocate to each fund are shown in Table
   4.

 What are some of the funds' potential risks?
 
   Each Spectrum Fund's share price will fluctuate as the share prices of the
   underlying funds rise or fall with changing market conditions.
 
 
   o For Spectrum Income, a rise in U.S. interest rates is an important source
     of risk even if foreign rates behave differently.
 
   Spectrum Income Fund: The risks are generally the same as with many income
   funds:
 
  . Interest rate or market risk The fund's share price will generally move in
   the opposite direction of interest rates. For example, as interest rates
   rise, share price will likely decline. Rising rates provide the opportunity
   for the fund's income to increase, but it is unlikely that the higher income
   by itself will entirely offset the fall in price.
 
   The maturity and type of securities in the underlying funds' portfolios
   determine just how much the share price rises or falls when rates change.
   Generally, when rates fall, long-term securities rise more in price than
   short-term securities, and vice versa.
 
  . Credit risk The chance that holdings of the underlying funds will have their
   credit ratings downgraded or will default, potentially reducing the
   underlying fund's share price and income level. This risk is even greater
   with high-yield ("junk") bonds.
 
  . Risks of high-yield investing The total return and yield of lower-quality
   (high-yield, high-risk) bonds, commonly referred to as "junk" bonds, can be
   expected to fluctuate more than the total return and yield of higher-quality
   bonds. Junk
   bonds are regarded as predominately speculative with respect to the issuer's
   continuing ability to meet principal and interest payments. Successful
   investment in low- and lower-medium-quality bonds involves greater investment
   risk and is highly dependent on T. Rowe Price's credit analysis. A real or
   perceived economic downturn or higher rates could cause a decline in
   high-yield bond prices because such events could lessen the ability of
   issuers to make principal and interest payments. In addition, the entire junk
   bond market can experience sudden and sharp price swings due to a variety of
   factors. Spectrum Income can invest as much as 25% of its assets in the High
   Yield Fund.
 
  . Prepayment risk With mortgage-backed securities, there is a chance that,
   when interest rates are falling, homeowners will accelerate principal
   payments on mortgages, causing a loss to investors in mortgage-backed
   securities that were originally purchased at a price above par. Also, because
   of prepayments, mortgage-backed securities would not be expected to rise as
   much in price as Treasury or corporate bonds.
 
  . Risks of foreign investing To the extent its underlying funds invest in
   foreign securities, the Spectrum Income Fund will be subject to the unique
   risks of international investing. See Spectrum International for an
   explanation of these risks.
 
   Also, Spectrum Income Fund's maximum 25% exposure to the Equity Income Fund
   subjects that portion of assets to the risks associated with stocks
   (discussed next).
 
 
   o For Spectrum Growth, a decline in U.S. stock prices is an important source
     of risk even if foreign stocks behave differently.
 
   
   Spectrum Growth Fund: The major risks are the same as in all stock funds:    
 
  . Stock market risk Economic growth has been punctuated by periods of
   stagnation and recession. Share prices of all companies, even the best
   managed and most profitable, can fall for any number of reasons, ranging from
   lower-than-expected earnings to changes in investor psychology. Significant
   trading by large institutional investors also can lead to price declines.
   Since 1950, the U.S. stock market has experienced 10 negative years, as well
   as steep drops of shorter duration. Its worst calendar quarter return in
   recent years was -22.5% in 1987's fourth quarter.
 
  . Small-company investing Since Spectrum Growth can invest up to 25% of its
   assets in the New Horizons Fund, it is subject to the risks of small-company
   investing. Smaller companies are generally riskier than their larger
   counterparts because they may have limited product lines, capital, and
   managerial resources. Their securities may trade less frequently and with
   greater price swings.
 
  . Risks of foreign investing To the extent its underlying funds invest in
   foreign securities, the Spectrum Growth Fund will be subject to the unique
   risks of international investing. See Spectrum International for an
   explanation of these risks.
 
 
   o For Spectrum International, volatility of foreign currency markets is an
     additional source of risk.
 
   
   Spectrum International Fund: In addition to the risks associated with stock
   and bond investing, the fund is subject to the unique risks of international
   investing:
 
  . Currency risk The risk that weakening foreign currencies versus the U.S.
   dollar could result in losses for U.S. investors. Transactions in foreign
   markets are conducted in local currencies, so dollars are exchanged for
   foreign currency when a security is bought or sold or a dividend is paid.
   Likewise, share price quotations and total return information reflect
   conversion into U.S. dollars. Fluctuations in foreign exchange rates can
   significantly increase or decrease the dollar value of a foreign investment,
   boosting or offsetting its local market return. For example, if a French
   security rose 10% in price during a year, but the U.S. dollar gained 5%
   against the French franc during that time, the U.S. investor's return would
   be reduced to 5%. This is because the franc would "buy" fewer dollars at the
   end of the year than at the beginning, or, conversely, a dollar would cost
   more francs. The fund's total return will be affected by currency
   fluctuations. The exact amount of the impact depends on the currencies
   represented in the portfolio and how each one appreciates or depreciates in
   relationship to the U.S. dollar.    
 
  . Increased costs It is more expensive for U.S. investors to trade in foreign
   markets than in the U.S. Mutual funds offer an efficient way for individuals
   to invest abroad, but the overall expense ratios of international funds are
   usually higher than those of typical domestic funds.
 
  . Political and economic factors The economies, markets, and political
   structures of a number of the countries in which the underlying funds can
   invest do not compare favorably with the U.S. and other mature economies in
   terms of wealth and stability. Therefore, investments in these countries will
   be riskier and subject to more erratic and abrupt price movements. This is
   especially true for emerging markets. However, even investments in countries
   with highly developed economies are subject to risk.
 
   
   Some economies are less developed, heavily dependent on particular
   industries, and more vulnerable to the ebb and flow of international trade,
   trade barriers, and other protectionist or retaliatory measures. This makes
   investment in such markets significantly riskier than in other countries.
   Many countries have legacies and the risk of hyperinflation and currency
   devaluations versus the dollar (which adversely affects returns to U.S.
   investors), and may be overly dependent on foreign capital (a risk that is
   exacerbated by big currency movements). Invest-
   ments in countries that have recently begun moving away from central planning
   and state-owned industries toward free markets should be regarded as
   speculative.
 
   Certain areas have histories of instability and upheaval with respect to
   their internal politics that could cause their governments to act in a
   detrimental or hostile manner toward private enterprise or foreign
   investment. Actions such as capital controls, nationalizing a company or
   industry, expropriating assets, or imposing punitive taxes could have a
   severe effect on security prices and impair an underlying fund's ability to
   repatriate capital or income. Significant external risks, including war,
   currently affect some countries. Governments in many emerging market
   countries participate to a significant degree in their economies and
   securities markets.    
 
  . Legal, regulatory, and operational Certain countries lack uniform
   accounting, auditing, and financial reporting standards, have less
   governmental supervision of financial markets than in the U.S., do not honor
   legal rights enjoyed in the U.S., and have settlement practices, such as
   delays, which could subject the underlying funds to risks of loss not
   customary in the U.S. In addition, securities markets in some countries have
   substantially lower trading volumes than in U.S. markets, resulting in less
   liquidity and more volatility than experienced in the U.S.
 
  . Pricing Portfolio securities of the underlying funds may be listed on
   foreign exchanges that are open on days when prices are not computed for the
   underlying funds. As a result, the net asset value of the underlying funds,
   and consequently of Spectrum International, may be significantly affected by
   trading on days when shareholders cannot make transactions.
 
   The risks discussed can be significantly magnified for investments in
   emerging markets. Additionally, to the extent the fund invests in the
   International Bond Fund and Emerging Markets Bond Fund, it will be subject to
   risks associated with international fixed income investing. See Spectrum
   Income Fund for information on the risks associated with fixed income
   investing.
 
 
   o Each fund's share price will fluctuate; when you sell your shares, you may
     lose money.
 
 
 What are some of the Spectrum Funds' potential rewards?
 
   The Spectrum Funds offer a professionally managed allocation of assets among
   a broad range of underlying funds. Because they invest in a variety of
   underlying funds, each Spectrum Fund's performance could benefit from
   diversification.
 
   The theory of diversification holds that investors can reduce their overall
   risk by spreading assets among a variety of investments. Each type of
   investment follows
   a cycle of its own and responds differently to changes in the economy and the
   marketplace. A decline in one investment can be balanced by returns in other
   investments that are stable or rising. Therefore, a major benefit of the
   Spectrum Funds is the potential for attractive long-term returns with reduced
   volatility.
 
   For example, Spectrum Income Fund invests in funds holding high-quality
   domestic and foreign bonds, high-yield bonds, short- and long-term
   securities, and dividend-paying stocks.
 
   Spectrum Growth Fund invests in funds holding domestic and foreign stocks,
   small- and large-cap stocks, and growth and value stocks.
 
   
   Spectrum International Fund invests in stock and, to a lesser degree, bond
   funds, which, in turn, have holdings in many different foreign countries,
   industrialized as well as emerging markets, and in both large and small
   companies.    
 
 
 What are the characteristics of the underlying Price funds?
 
   For details, please see Description of Underlying Funds in Section 3.
 
 
 How can I decide which fund is most appropriate for me?
 
   Consider your investment goals, your time horizon for achieving them, and
   your tolerance for risk.
 
   If you would like a one-stop approach to broad diversification and can accept
   the possibility of moderate share price declines in an effort to achieve
   relatively high income, Spectrum Income Fund could be an appropriate part of
   your overall investment strategy.
 
   If you seek one-stop diversification and can accept the possibility of
   greater share price declines in an effort to achieve long-term capital
   appreciation, Spectrum Growth Fund could be an appropriate part of your
   overall investment strategy.
 
   If your goal is long-term capital appreciation with a one-stop approach to
   diversification across the international markets, and you can accept the
   possibility of significant share price declines, Spectrum International Fund
   could be an appropriate part of your overall investing strategy.
 
   For an IRA, retirement plan, or other long-term investment, the funds offer
   investment programs that seek to combine attractive returns with the benefits
   of broad diversification.

 PRICING SHARES AND RECEIVING SALE PROCEEDS
 ----------------------------------------------------------
   Here are some procedures you should know when investing in a T. Rowe Price
   equity fund.
 
 
 How and when shares are priced
 
   The share price (also called "net asset value" or NAV per share) for a fund
   is calculated at 4 p.m. ET each day the New York Stock Exchange is open for
   business. To calculate the NAV, the fund's assets are valued and totaled,
   liabilities are subtracted, and the balance, called net assets, is divided by
   the number of shares outstanding.
 
   
   o The various ways you can buy, sell, and exchange shares are explained at
     the end of this prospectus and on the New Account Form. These procedures
     and the information you receive about them may differ for institutional and
     employer-sponsored retirement accounts.    
 
 
 How your purchase, sale, or exchange price is determined
 
   If we receive your request in correct form by 4 p.m. ET, your transaction
   will be priced at that day's NAV. If we receive it after 4 p.m., it will be
   priced at the next business day's NAV.
 
   We cannot accept orders that request a particular day or price for your
   transaction or any other special conditions.
 
   
   Fund shares may be purchased through various third-party intermediaries,
   including banks, brokers, and investment advisers. Where authorized by a
   fund, orders will be priced at the NAV next computed after receipt by the
   intermediary. Consult your intermediary to determine when your orders will be
   priced. The intermediary may charge a fee for its services.    
 
   Note: The time at which transactions and shares are priced and the time until
   which orders are accepted may be changed in case of an emergency or if the
   New York Stock Exchange closes at a time other than 4 p.m. ET.
 
 
 How you can receive the proceeds from a sale
 
 
   o When filling out the New Account Form, you may wish to give yourself the
     widest range of options for receiving proceeds from a sale.
<PAGE>
 
   
   If your request is received by 4 p.m. ET in correct form, proceeds are
   usually sent on the next business day. Proceeds can be sent to you by mail or
   to your bank account by Automated Clearing House (ACH) transfer or bank wire.
   Proceeds sent by ACH transfer should be credited the second day after the
   sale. ACH is an automated method of initiating payments from, and receiving
   payments in, your financial institution account. The ACH system is supported
   by over 20,000 banks, savings banks, and credit unions. Proceeds sent by bank
   wire should be credited to your account the next business day.
 
  . Exception: Under certain circumstances and when deemed to be in the fund's
   best interests, your proceeds may not be sent for up to five business days
   after we receive your sale or exchange request. If you were exchanging into a
   bond or money fund, your new investment would not begin to earn dividends
   until the sixth business day.    
 
 
   o If for some reason we cannot accept your request to sell shares, we will
     contact you.
 
 
 
 USEFUL INFORMATION ON DISTRIBUTIONS AND TAXES
 ----------------------------------------------------------
 
   o All net investment income and realized capital gains are distributed to
     shareholders.
 
 
 Dividends and Other Distributions
 
   Dividend and capital gain distributions are reinvested in additional fund
   shares in your account unless you select another option on your New Account
   Form. The advantage of reinvesting distributions arises from compounding;
   that is, you receive income dividends and capital gain distributions on a
   rising number of shares.
 
   Distributions not reinvested are paid by check or transmitted to your bank
   account via ACH. If the Post Office cannot deliver your check, or if your
   check remains uncashed for six months, the fund reserves the right to
   reinvest your distribution check in your account at the NAV on the business
   day of the reinvestment and to reinvest all subsequent distributions in
   shares of the fund. No interest will accrue on amounts represented by
   uncashed distribution or redemption checks.
<PAGE>
 
   Income dividends
   Spectrum Income Fund dividends
  . The fund declares income dividends daily at 4 p.m. ET to shareholders of
   record at that time provided payment has been received on the previous
   business day.
 
  . The fund pays dividends on the first business day of each month.
 
  . Fund shares will earn dividends through the date of redemption; also, shares
   redeemed on a Friday or prior to a holiday will continue to earn dividends
   until the next business day. Generally, if you redeem all of your shares at
   any time during the month, you will also receive all dividends earned through
   the date of redemption in the same check. When you redeem only a portion of
   your shares, all dividends accrued on those shares will be reinvested, or
   paid in cash, on the next dividend payment date.
 
  . A portion of the fund's dividends may be eligible for the 70% deduction for
   dividends received by corporations.
 
   Spectrum Growth Fund dividends
  . The fund declares and pays dividends (if any) annually.
 
  . A portion of the fund's dividends may be eligible for the 70% deduction for
   dividends received by corporations.
 
   Spectrum International Fund dividends
  . The fund declares and pays dividends (if any) annually.
 
  . The dividends of the fund will not be eligible for the 70% deduction for
   dividends received by corporations, if, as expected, none of the fund's
   income consists of dividends paid by U.S. corporations.
 
   Capital gains (all funds)
  . A capital gain or loss is the difference between the purchase and sale price
   of a security.
 
  . If a fund has net capital gains for the year (after subtracting any capital
   losses), they are usually declared and paid in December to shareholders of
   record on a specified date that month.
 
 
 Tax Information
 
 
   o You will be sent timely information for your tax filing needs.
 
   You need to be aware of the possible tax consequences when:
 
  . You sell fund shares, including an exchange from one fund to another.
 
  . The fund makes a distribution to your account.
<PAGE>
 
   Taxes on fund redemptions
   When you sell shares in any fund, you may realize a gain or loss. An exchange
   from one fund to another is still a sale for tax purposes.
 
   
   In January, you will be sent Form 1099-B indicating the date and amount of
   each sale you made in the fund during the prior year. This information will
   also be reported to the IRS. For new accounts or those opened by exchange in
   1983 or later, we will provide the gain or loss on the shares you sold during
   the year, based on the "average cost," single category method. This
   information is not reported to the IRS, and you do not have to use it. You
   may calculate the cost basis using other methods acceptable to the IRS, such
   as "specific identification."    
 
   To help you maintain accurate records, we send you a confirmation immediately
   following each transaction you make (except for systematic purchases and
   redemptions) and a year-end statement detailing all your transactions in each
   fund account during the year.
 
   Taxes on fund distributions
 
   o The following summary does not apply to retirement accounts, such as IRAs,
     which are tax-deferred until you withdraw money from them.
 
   
   In January, you will be sent Form 1099-DIV indicating the tax status of any
   dividend and capital gain distributions made to you. This information will
   also be reported to the IRS. Distributions made by a fund are generally
   taxable to you for the year in which they were paid. You will be sent any
   additional information you need to determine your taxes on fund
   distributions, such as the portion of your dividend, if any, that may be
   exempt from state income taxes.
 
   The tax treatment of a capital gain distribution is determined by how long
   the fund held the portfolio securities, not how long you held shares in the
   fund. Short-term (one year or less) capital gain distributions are taxable at
   the same rate as ordinary income. Reflecting recent changes in the tax code,
   gains on securities held more than 12 months but not more than 18 months are
   taxed at a maximum rate of 28%, and gains on securities held for more than 18
   months are taxed at a maximum rate of 20%. If you realize a loss on the sale
   or exchange of fund shares held six months or less, your short-term loss
   recognized is reclassified to long term to the extent of any net capital gain
   distribution received.    
 
   You will not be able to claim a credit or deduction for any foreign taxes
   paid by the underlying funds.
 
   Gains and losses from the sale of foreign currencies and the foreign currency
   gain or loss resulting from the sale of a foreign debt security can increase
   or decrease a fund's ordinary income dividend. Net foreign currency losses
   may result in a fund's dividend being classified as a return of capital.
 
   If a fund pays nonrefundable taxes to foreign governments during the year,
   the taxes will reduce the fund's dividends but will still be included in your
   taxable income. However, you may be able to claim an offsetting deduction on
   your tax return for your portion of foreign taxes paid by a fund.
 
 
   o Distributions are taxable whether reinvested in additional shares or
     received in cash.
 
   Tax effect of buying shares before a capital gain or dividend distribution
   
   If you buy shares shortly before or on the "record date" -  the date that
   establishes you as the person to receive the upcoming distribution - you will
   receive a portion of the money you just invested in the form of a taxable
   distribution. Therefore, you may wish to find out a fund's record date before
   investing. Of course, a fund's share price may, at any time, reflect
   undistributed capital gains or income and unrealized appreciation, which may
   result in future distributions.    
 
 
 
 TRANSACTION PROCEDURES AND SPECIAL REQUIREMENTS
 ----------------------------------------------------------
 
   o Following these procedures helps assure timely and accurate transactions.
 
 
 Purchase Conditions
 
   Nonpayment
   If your payment is not received or you pay with a check or ACH transfer that
   does not clear, your purchase will be canceled. You will be responsible for
   any losses or expenses incurred by the fund or transfer agent, and the fund
   can redeem shares you own in this or another identically registered T. Rowe
   Price fund as reimbursement. The fund and its agents have the right to reject
   or cancel any purchase, exchange, or redemption due to nonpayment.
 
   U.S. dollars
   All purchases must be paid for in U.S. dollars; checks must be drawn on U.S.
   banks.
 
 
 Sale (Redemption) Conditions
 
   10-day hold
   If you sell shares that you just purchased and paid for by check or ACH
   transfer, the fund will process your redemption but will generally delay
   sending you the proceeds for up to 10 calendar days to allow the check or
   transfer to clear. If your redemption request was sent by mail or mailgram,
   proceeds will be mailed no later than the seventh calendar day following
   receipt unless the check or ACH transfer has not cleared. (The 10-day hold
   does not apply to the following: pur-
   chases paid for by bank wire; cashier's, certified, or treasurer's checks; or
   automatic purchases through your paycheck.)
 
   Telephone, Tele*Access/(R)/, and personal computer transactions
   
   Exchange and redemption services through telephone and Tele*Access are
   established automatically when you sign the New Account Form unless you check
   the box that states you do not want these services. Personal computer
   transactions must be authorized separately. T. Rowe Price funds and their
   agents use reasonable procedures (including shareholder identity
   verification) to confirm that instructions given by telephone are genuine and
   are not liable for acting on these instructions. If these procedures are not
   followed, it is the opinion of certain regulatory agencies that the funds and
   their agents may be liable for any losses that may result from acting on the
   instructions given. A confirmation is sent promptly after a transaction. All
   telephone conversations are recorded.    
 
   Redemptions over $250,000
   Large sales can adversely affect a portfolio manager's ability to implement a
   fund's investment strategy by causing the premature sale of securities that
   would otherwise be held. If, in any 90-day period, you redeem (sell) more
   than $250,000, or your sale amounts to more than 1% of fund net assets, the
   fund has the right to pay the difference between the redemption amount and
   the lesser of the two previously mentioned figures with securities from the
   fund.
 
 
 Excessive Trading
 
 
   o T. Rowe Price may bar excessive traders from purchasing shares.
 
   Frequent trades, involving either substantial fund assets or a substantial
   portion of your account or accounts controlled by you, can disrupt management
   of the fund and raise its expenses.
 
  . Trades placed directly with T. Rowe Price If you trade directly with T. Rowe
   Price, you can make one purchase and sale involving the same fund within any
   120-day period. For example, if you are in fund A, you can move substantial
   assets from fund A to fund B and, within the next 120 days, sell your shares
   in fund B to return to fund A or move to fund C. If you exceed this limit,
   you are in violation of our excessive trading policy.
 
   Two types of transactions are exempt from this policy: 1) trades solely in
   money market funds (exchanges between a money fund and a non-money fund are
   not exempt); and 2) systematic purchases or redemptions (see Shareholder
   Services).
 
  . Trades placed through intermediaries If you purchase fund shares through an
   intermediary including a broker, bank, investment adviser, or other third
   party and hold them for less than 60 calendar days, you are in violation of
   our excessive trading policy.
<PAGE>
 
  . If you violate our excessive trading policy, you may be barred indefinitely
   and without further notice from further purchases of T. Rowe Price funds.
 
 
 Keeping Your Account Open
 
   Due to the relatively high cost to a fund of maintaining small accounts, we
   ask you to maintain an account balance of at least $1,000. If your balance is
   below $1,000 for three months or longer, we have the right to close your
   account after giving you 60 days in which to increase your balance.
 
 
 Small Account Fee
 
   Because of the disproportionately high costs of servicing accounts with low
   balances, a $10 fee, paid to T. Rowe Price Services, the fund's transfer
   agent, will automatically be deducted from nonretirement accounts with
   balances falling below a minimum level. The valuation of accounts and the
   deduction are expected to take place during the last five business days of
   September. The fee will be deducted from accounts with balances below $2,000,
   except for UGMA/ UTMA accounts, for which the limit is $500. The fee will be
   waived for any investor whose aggregate T. Rowe Price mutual fund investments
   total $25,000 or more. Accounts employing automatic investing (e.g., payroll
   deduction, automatic purchase from a bank account, etc.) are also exempt from
   the charge. The fee will not apply to IRAs and other retirement plan
   accounts. (A separate custodial fee may apply to IRAs and other retirement
   plan accounts.)
 
 
 Signature Guarantees
 
 
   o A signature guarantee is designed to protect you and the T. Rowe Price
     funds from fraud by verifying your signature.
 
   You may need to have your signature guaranteed in certain situations, such
   as:
 
  . Written requests 1) to redeem over $100,000, or 2) to wire redemption
   proceeds.
 
  . Remitting redemption proceeds to any person, address, or bank account not on
   record.
 
  . Transferring redemption proceeds to a T. Rowe Price fund account with a
   different registration (name or ownership) from yours.
 
  . Establishing certain services after the account is opened.
 
   You can obtain a signature guarantee from most banks, savings institutions,
   broker-dealers, and other guarantors acceptable to T. Rowe Price. We cannot
   accept guarantees from notaries public or organizations that do not provide
   reimbursement in the case of fraud.

 ORGANIZATION AND MANAGEMENT
 ----------------------------------------------------------
 
 How are the funds organized?
 
   The T. Rowe Price Spectrum Fund, Inc. (Spectrum Fund) is a Maryland
   corporation organized in 1987 and is registered with the Commission under the
   1940 Act as a nondiversified, open-end investment company, commonly known as
   a "mutual fund." Mutual funds pool money received from shareholders and
   invest it to try to achieve specified objectives.
 
   Currently, Spectrum Fund consists of three series, the Spectrum Income Fund,
   the Spectrum Growth Fund, and the Spectrum International Fund (collectively
   referred to as "the funds"), each of which represents a separate class of
   shares and has different objectives and investment policies. The Spectrum
   Income and Spectrum Growth Funds were established in 1990, and the Spectrum
   International Fund was established in 1996.
 
   
   o Shareholders benefit from T. Rowe Price's 61 years of investment management
     experience.    
 
 
 What is meant by "shares"?
 
   As with all mutual funds, investors purchase shares when they put money in a
   fund. These shares are part of a fund's authorized capital stock, but share
   certificates are not issued.
 
   Each share and fractional share entitles the shareholder to:
 
  . Receive a proportional interest in a fund's income and capital gain
   distributions.
 
  . Cast one vote per share on certain fund matters, including the election of
   fund directors, changes in fundamental policies, or approval of changes in
   the fund's management contract.
 
 
 Do T. Rowe Price funds have annual shareholder meetings?
 
   
   The funds are not required to hold annual meetings and, to avoid unnecessary
   costs to fund shareholders, do not intend to do so except when certain
   matters, such as a change in a fund's fundamental policies, must be decided.
   In addition, shareholders representing at least 10% of all eligible votes may
   call a special meeting, if they wish, for the purpose of voting on the
   removal of any fund direc-
   tor or trustee. If a meeting is held and you cannot attend, you can vote by
   proxy. Before the meeting, the fund will send you proxy materials that
   explain the issues to be decided and include a voting card for you to mail
   back.    
 
 
 Who runs the funds?
 
   General Oversight
   
   Spectrum Fund is governed by a Board of Directors that meets regularly to
   review the funds' investments, performance, expenses, and other business
   affairs. The Board elects the funds' officers. The policy of the funds is
   that a majority of the Board members are independent of T. Rowe Price and
   Price-Fleming and that none of the independent directors will be directors of
   any underlying fund. In exercising their responsibilities, the Board, among
   other things, will refer to the Special Servicing Agreements and policies and
   guidelines included in the Exemptive Order ("Order") issued by the Securities
   and Exchange Commission in connection with the operation of the funds. The
   interested directors and the officers of Spectrum Fund and T. Rowe Price and
   Price-Fleming also serve in similar positions with most of the underlying
   funds. Thus, if the interests of a Spectrum Fund and the underlying funds
   were ever to diverge, it is possible that a conflict of interest could arise
   and affect how the interested directors and officers fulfill their fiduciary
   duties to that fund and the underlying funds. The directors of Spectrum Fund
   believe they have structured each fund to avoid these concerns. However,
   conceivably, a situation could occur where proper action for a Spectrum Fund
   could be adverse to the interests of an underlying fund, or the reverse. If
   such a possibility arises, the directors and officers of the affected funds
   and T. Rowe Price or Price-Fleming, as applicable, will carefully analyze the
   situation and take all steps they believe reasonable to minimize and, where
   possible, eliminate the potential conflict.    
 
   Portfolio Management: Spectrum Income and Spectrum Growth Funds
   
   Spectrum Income and Spectrum Growth Funds have an Investment Advisory
   Committee with the following members: Peter Van Dyke, Chairman, Stephen W.
   Boesel, John H. Laporte, Edmund M. Notzon III, William T. Reynolds, Brian C.
   Rogers, Charles P. Smith, and M. David Testa. The committee chairman has
   day-to-day responsibility for managing the Spectrum Income and Spectrum
   Growth Funds and works with the committee in developing and executing these
   funds' investment programs. Mr. Van Dyke has been chairman of the committee
   since 1990. He has been managing investments since joining T. Rowe Price in
   1985.    
 
   Portfolio Management: Spectrum International Fund
   
   Spectrum International has an Investment Advisory Committee with the
   following members: John R. Ford, Chairman, M. David Testa, Martin G. Wade,
   and David J. L. Warren. The committee chairman has day-to-day responsibility
   for managing this fund and works with the committee in developing and
   executing the
   fund's investment program. Mr. Ford joined Price-Fleming in 1982 and has 18
   years of experience in managing investments.    
 
   Management of the Underlying Funds
   T. Rowe Price serves as investment manager to all of the underlying domestic
   funds. Price-Fleming serves as investment manager to all of the underlying
   international funds. Each manager is responsible for selection and management
   of the underlying funds' portfolio investments. T. Rowe Price serves as
   investment manager to a variety of individual and institutional investors,
   including limited and real estate partnerships and other mutual funds.
 
   Price-Fleming was incorporated in Maryland in 1979 as a joint venture between
   T. Rowe Price and Robert Fleming Holdings Limited (Flemings). Flemings is a
   diversified investment organization which participates in a global network of
   regional investment offices in New York, London, Zurich, Geneva, Tokyo, Hong
   Kong, Manila, Kuala Lumpur, Seoul, Taipei, Bombay, Jakarta, Singapore,
   Bangkok, and Johannesburg. Flemings was incorporated in 1974 in the United
   Kingdom as successor to the business founded by Robert Fleming in 1873.
 
   T. Rowe Price, Flemings, and Jardine Fleming are owners of Price-Fleming. The
   common stock of Price-Fleming is 50% owned by a wholly owned subsidiary of T.
   Rowe Price, 25% by a subsidiary of Flemings, and 25% by a subsidiary of
   Jardine Fleming Group Limited (Jardine Fleming). (Half of Jardine Fleming is
   owned by Flemings and half by Jardine Matheson Holdings Limited.) T. Rowe
   Price has the right to elect a majority of the Board of Directors of
   Price-Fleming, and Flemings has the right to elect the remaining directors,
   one of whom will be nominated by Jardine Fleming.
 
   Marketing
   T. Rowe Price Investment Services, Inc., a wholly owned subsidiary of T. Rowe
   Price, distributes (sells) shares of these and all other T. Rowe Price funds.
 
   Shareholder Services
   T. Rowe Price Services, Inc., another wholly owned subsidiary, acts as each
   fund's transfer and dividend disbursing agent and provides shareholder and
   administrative services. Services for certain types of retirement plans are
   provided by T. Rowe Price Retirement Plan Services, Inc., also a wholly owned
   subsidiary. The address for each is 100 East Pratt St., Baltimore, MD 21202.
 
 
 How are fund expenses determined?
 
   Each Spectrum Fund will operate at a zero expense ratio. However, each fund
   will incur its pro-rata share of the fees and expenses of the underlying
   funds in which they invest. The payment of each fund's operational expenses
   is subject to a Special Servicing Agreement (described next) as well as
   certain undertakings made by T. Rowe Price and Price-Fleming under their
   respective Investment
   Management Agreements with each Spectrum Fund. Fund expenses include:
   shareholder servicing fees and expenses; custodian and accounting fees and
   expenses; legal and auditing fees; expenses of preparing and printing
   prospectuses and shareholder reports; registration fees and expenses; proxy
   and annual meeting expenses, if any; and directors' fees and expenses.
 
 
   o Here is some information regarding the Special Servicing Agreements.
 
   
   The Special Servicing Agreements provide that each underlying fund in which a
   Spectrum Fund invests will bear a proportionate share of the expenses of that
   Spectrum Fund if, and to the extent that, the underlying fund's savings from
   the operation of Spectrum Fund exceed these expenses.    
 
   Such savings are expected to result primarily from the elimination of
   numerous separate shareholder accounts which are or would have been invested
   directly in the underlying Price Funds and the resulting reduction in
   shareholder servicing costs. Although such cost savings are not certain, the
   estimated savings to the underlying Price Funds generated by the operation of
   Spectrum Fund are expected to be sufficient to offset most, if not all, of
   the expenses incurred by Spectrum Fund.
 
   
   Under the Investment Management Agreements with the Spectrum Fund, and the
   Special Servicing Agreements, T. Rowe Price has agreed to bear any expenses
   of the Spectrum Growth and Spectrum Income Funds and Price-Fleming has agreed
   to bear any expenses of the Spectrum International Fund which exceed the
   estimated savings to each of the underlying funds. Thus, the Spectrum Funds
   will operate at a zero expense ratio. Of course, shareholders of the Spectrum
   Funds will still indirectly bear their fair and proportionate share of the
   cost of operating the underlying funds owned by each Spectrum Fund.    
 
   The Management Fee
   
   T. Rowe Price is the investment manager for the Spectrum Income Fund and the
   Spectrum Growth Fund, and Price-Fleming is investment manager for the
   Spectrum International Fund. Neither will be paid a management fee for
   performing such services. However, T. Rowe Price and Price-Fleming receive
   management fees from managing the underlying funds. See the underlying funds'
   Statements of Additional Information for specific fees.
 
   T. Rowe Price will determine how Spectrum Income Fund's and Spectrum Growth
   Fund's assets are invested and Price-Fleming will determine how the Spectrum
   International Fund's assets will be invested consistent with the investment
   objectives and policies of each fund described in this prospectus and
   procedures and guidelines established by the Board of Directors for the
   Spectrum Fund. The Directors for Spectrum Fund will periodically monitor the
   allocations and the basis upon which such allocations were made or
   maintained.

 UNDERSTANDING PERFORMANCE INFORMATION
 ----------------------------------------------------------
   This section should help you understand the terms used to describe fund
   performance. You will come across them in shareholder reports you receive
   from us; in our newsletter, The Price Report; in Insights articles; in T.
   Rowe Price advertisements; and in the media.
 
 
 Total Return
 
   
   This tells you how much an investment in a fund has changed in value over a
   given time period. It reflects any net increase or decrease in the share
   price and assumes that all dividends and capital gains (if any) paid during
   the period were reinvested in additional shares. Therefore, total return
   numbers include the effect of compounding.
 
   Advertisements for a fund may include cumulative or average annual compound
   total return figures, which may be compared with various indices, other
   performance measures, or other mutual funds.    
 
 
   o Total return is the most widely used performance measure. Detailed
     performance information is included in each fund's annual and semiannual
     shareholder reports and in the quarterly Performance Update, which are all
     available without charge.
 
 
 Cumulative Total Return
 
   
   This is the actual return of an investment for a specified period. A
   cumulative return does not indicate how much the value of the investment may
   have fluctuated during the period. For example, a fund could have a 10-year
   positive cumulative return despite experiencing three negative years during
   that time.    
 
 
 Average Annual Total Return
 
   
   This is always hypothetical and should not be confused with actual
   year-by-year results. It smooths out all the variations in annual performance
   to tell you what constant year-by-year return would have produced the
   investment's actual cumulative return. This gives you an idea of an
   investment's annual contribution to your portfolio, provided you held it for
   the entire period.    
 
 
 Yield (Spectrum Income Fund)
 
 
   o You will see frequent references to a fund's yield in our reports, in
     advertisements, in media stories, and so on.
 
   The current or "dividend" yield on a fund or any investment tells you the
   relationship between the investment's current level of annual income and its
   price on a particular day. The dividend yield reflects the actual income paid
   to shareholders for a given period, annualized, and divided by the fund's net
   asset value.
<PAGE>
 
   For example, a fund providing $5 of annual income per share and a price of
   $50 has a current yield of 10%. Yields can be calculated for any time period.
 
   The advertised or "SEC" yield is found by determining the net income per
   share (as defined by the SEC) earned by a fund during a 30-day base period
   and dividing this amount by the per share price on the last day of the base
   period. The SEC yield may differ from the dividend yield.
 
 
 
 SPECIAL RISKS AND CONSIDERATIONS
 ----------------------------------------------------------
   Prospective investors should consider the following factors:
 
  . The investments of each Spectrum Fund are concentrated in the underlying
   funds, so each fund's investment performance is directly related to the
   investment performance of these underlying funds.
 
  . As an operating policy, the Spectrum Income and Spectrum Growth Funds will
   not redeem more than 1% of any underlying fund's assets during any period
   less than 15 days, except when necessary to meet the fund's shareholder
   redemption requests. As a result, the funds may not be able to reallocate
   assets among the underlying funds as efficiently and rapidly as would be the
   case in the absence of this constraint. This limitation does not apply to
   Spectrum International Fund.
 
 
   o Further information on these investment policies and practices can be found
     under Investment Policies of the Underlying Funds and in the Statement of
     Additional Information, as well as in the prospectuses of each of the
     underlying funds.
 
   
  . For Spectrum International Fund, each underlying fund's portfolio securities
   usually are valued on the basis of the most recent closing market prices at 4
   p.m. ET when each fund calculates its NAV. Most of the securities in which
   the underlying funds invest, however, are traded in markets that close before
   that time. For securities primarily traded in the Far East, for example, the
   most recent closing prices may be as much as 15 hours old at 4 p.m. Normally,
   developments that could affect the values of portfolio securities that occur
   between the close of the foreign market and 4 p.m. ET will not be reflected
   in the funds' NAVs. However, if a fund determines that such developments are
   so significant that they will clearly and materially affect the value of the
   fund's securities, the fund may adjust the previous closing prices to reflect
   fair value or use the next available opening market prices to value its
   portfolio securities.    
 
  . The officers, interested directors, and investment managers of Spectrum
   Funds presently serve as officers, interested directors, and investment
   managers of the
   underlying funds. Therefore, conflicts may arise as these persons fulfill
   their fiduciary responsibilities to the Spectrum Funds and the underlying
   funds.

 INVESTMENT POLICIES OF THE SPECTRUM FUNDS
 ----------------------------------------------------------
   Each Spectrum Fund's investment policies and practices are subject to further
   restrictions and risks which are described in the Statement of Additional
   Information. The funds will not make a material change in their investment
   objectives or their fundamental policies without obtaining shareholder
   approval. Shareholders will be notified of any material change in such
   investment programs.
 
   Reserve Position
   While the Spectrum Income Fund will remain primarily invested in bonds, the
   Spectrum Growth Fund in stocks, and the Spectrum International Fund in
   international stocks, each fund can hold a certain portion of its assets in
   U.S. and foreign dollar-denominated money market securities, including
   repurchase agreements in the two highest rating categories, maturing in one
   year or less. For temporary, defensive purposes, a fund may invest without
   limitation in such securities. Each fund may invest its cash reserves in the
   Summit Cash Reserves
   Fund. A reserve position provides flexibility in meeting redemptions,
   expenses, and the timing of new investments, and serves as a short-term
   defense during periods of unusual volatility.
 
   Diversification
   Spectrum Fund is a "nondiversified" investment company for purposes of the
   1940 Act because it invests in the securities of a limited number of mutual
   funds. However, the underlying funds themselves are diversified investment
   companies (with the exception of the T. Rowe Price International Bond Fund,
   Emerging Markets Bond Fund, and Latin America Fund). Spectrum Fund intends to
   qualify as a diversified investment company for the purposes of Subchapter M
   of the Internal Revenue Code.
 
   Fundamental investment policies As a matter of fundamental policy, each
   Spectrum Fund will not: (i) invest more than 25% of its respective total
   assets in any one industry, except for investment companies which are members
   of the T. Rowe Price family of funds; (ii) borrow money, except temporarily,
   to facilitate redemption requests in amounts not exceeding 30% of each fund's
   total assets valued at market; (iii) in any manner transfer as collateral for
   indebtedness any securities owned by each fund except in connection with
   permissible borrowings, which in no event will exceed 30% of each fund's
   total assets valued at market.
 
   Operating policies Each Spectrum Fund cannot (i) change the selection of the
   underlying funds in which they can invest; or (ii) change the percentage
   ranges which may be allocated to the underlying funds unless authorized to do
   so by the Board of Directors. Shareholders will be informed of any such
   changes.
 
   Other Investment Restrictions
   As a matter of operating policy, each Spectrum Fund will not, among other
   things: (i) purchase additional securities when money borrowed exceeds 5% of
   the fund's total assets; (ii) invest more than 10% of its net assets in
   illiquid securities; or (iii) redeem securities from any underlying fund at a
   rate in excess of 1% of the underlying fund's assets in any period of less
   than 15 days, except where necessary to meet shareholder redemption requests.
   This last limitation does not apply to Spectrum International Fund.
 
   Portfolio Turnover
   
   Each Spectrum Fund's portfolio turnover is expected to be low. The Spectrum
   Funds will purchase or sell securities to: (i) accommodate purchases and
   sales of each fund's shares; and (ii) maintain or modify the allocation of
   each fund's assets among the underlying funds within the percentage limits
   described earlier. The Spectrum Income Fund's and Spectrum Growth Fund's
   portfolio turnover
   rates for the previous three fiscal periods, and Spectrum International
   Fund's portfolio turnover rate for the previous period, are shown in Table 6.

 Year 2000 Processing Issue
 
   Many computer programs employed throughout the world use two digits rather
   than four to identify the year. These programs, if not adapted, will not
   correctly handle the change from "99" to "00" on January 1, 2000, and will
   not be able to perform necessary functions. The Year 2000 issue affects
   virtually all companies and organizations.
 
   T. Rowe Price has implemented steps intended to assure that its major
   computer systems and processes are capable of Year 2000 processing. We are
   working with third parties to assess the adequacy of their compliance efforts
   and are developing contingency plans intended to assure that third-party
   noncompliance will not materially affect T. Rowe Price's operations.
 
   Companies or governmental entities in which T. Rowe Price funds invest could
   be affected by the Year 2000 issue, but at this time the funds cannot predict
   the degree of impact. To the extent the impact on a portfolio holding is
   negative, a fund's returns could be adversely affected.    
 
 
 
 INVESTMENT POLICIES AND PRACTICES OF UNDERLYING FUNDS
 ----------------------------------------------------------
   
   In pursuing their investment objectives and programs, each of the underlying
   funds is permitted to engage in a wide range of investment practices. Certain
   of these practices are described in the following paragraphs and further
   information about the underlying funds is contained in the Statement of
   Additional Information as well as in the prospectuses of such funds. Because
   each fund invests in the underlying funds, shareholders of each fund will be
   affected by these investment practices in direct proportion to the amount of
   assets each fund allocates to the underlying funds pursuing such practices.
    
 
   o Fund managers have considerable leeway in choosing investment strategies
     and selecting securities they believe will help each fund achieve its
     objective.
 
   Lending of Portfolio Securities
   Like other mutual funds, the underlying funds may lend securities to
   broker-dealers, other institutions, or other persons to earn additional
   income. The principal risk is the potential insolvency of the broker-dealer
   or other borrower. In this event, the underlying funds could experience
   delays in recovering securities and possibly capital losses.
 
   Managing Foreign Currency Risk
   
   Foreign securities in which the underlying funds invest are subject to
   currency risk, that is, the risk that the U.S. dollar value of these
   securities may be affected favorably or unfavorably by changes in foreign
   currency exchange rates and exchange control regulations. Investors in
   foreign securities may "hedge" their exposure to potentially unfavorable
   currency changes by purchasing a contract to exchange one currency for
   another on some future date at a specified exchange rate. In certain
   circumstances, a "proxy currency" may be substituted for the currency in
   which the investment is denominated, a strategy known as "proxy hedging." An
   underlying fund may also use these contracts to create a synthetic
   bond-issued by a U.S. company, for example, but with the dollar component
   transformed into a foreign currency. If an underlying fund were to engage in
   foreign currency transactions, they would be used primarily to protect the
   fund's foreign securities from adverse currency movements relative to the
   dollar. Such transactions involve the risk that anticipated currency
   movements will not occur, and a fund's total return could be reduced.    
 
   There are certain markets where it is not possible to engage in effective
   foreign currency hedging. This may be true, for example, for the currencies
   of various Latin American countries and other emerging markets where the
   foreign exchange markets are not sufficiently developed to permit hedging
   activity to take place.
 
   Futures and Options
   
   Futures (a type of potentially high-risk derivative) are often used to manage
   or hedge risk, because they enable the investor to buy or sell an asset in
   the future at an agreed upon price. Options (another type of potentially
   high-risk derivative) give the investor the right (where the investor
   purchases the option), or the obligation (where the investor writes (sells)
   the option), to buy or sell an asset at a predetermined price in the future.
   The underlying funds may buy and sell futures and options contracts for a
   number of reasons, including: to manage their exposure to changes in interest
   rates, securities prices, and foreign currencies; to efficiently adjust their
   overall exposure to certain markets; to attempt to
   enhance income; to protect the value of portfolio securities; and to adjust
   the portfolios' duration.    
 
   The underlying funds may purchase, sell, or write call and put options on
   securities, financial indices, and foreign currencies.
 
   
   Futures contracts and options may not always be successful hedges and their
   prices can be highly volatile. Using them could lower the funds' total
   return; and the potential loss from the use of futures can exceed the funds'
   initial investment in such contracts. In many foreign countries, futures and
   options markets do not exist or are not sufficiently developed to be
   effectively used by the funds.

 INVESTMENT OBJECTIVES AND POLICIES
 -------------------------------------------------------------------------------
   The following information supplements the discussion of each Fund's
   investment objectives and policies discussed in the Funds' prospectus.
 
   The Funds will not make a material change in their investment objectives
   without obtaining shareholder approval. Unless otherwise specified, the
   investment programs and restrictions of the Funds are not fundamental
   policies. Each Fund's operating policies are subject to change by each Board
   of Directors without shareholder approval. However, shareholders will be
   notified of a material change in an operating policy. Each Fund's fundamental
   policies may not be changed without the approval of at least a majority of
   the outstanding shares of the Fund or, if it is less, 67% of the shares
   represented at a meeting of shareholders at which the holders of 50% or more
   of the shares are represented.
 
   Throughout this Statement of Additional Information, "the Fund" is intended
   to refer to each Fund listed on the cover page, unless otherwise indicated.
 
 
                                  Spectrum Fund
 
   The proliferation of mutual funds has left many investors in search of a
   means of diversifying among a number of mutual funds while obtaining
   professional management in determining which Funds to select, how much of
   their assets to commit to each Fund, and when to make the selections. In
   response to this need, the Spectrum Fund has been created as a means of
   providing a simple and effective means of structuring a comprehensive mutual
   fund investment program. By selecting the Spectrum Growth Fund, Spectrum
   Income Fund or Spectrum International Fund, or a combination of any of these,
   investors may choose the investment objective appropriate for their long-term
   investment goals. The Spectrum Funds will attempt to achieve these goals by
   diversification in a selected group of other T. Rowe Price Funds. Although
   the Spectrum Funds are not asset allocation or market timing funds, each,
   over time, will adjust the amount of its assets invested in the various other
   T. Rowe Price Funds as economic, market and financial conditions warrant.
 
   
   Described below are the underlying T. Rowe Price Funds in which the Spectrum
   Funds can invest.    
<PAGE>
 
   
                                Income Funds    
 
   T. Rowe Price Short-Term Bond Fund, Inc.
 
   The Fund's objective is a high level of income consistent with minimal
   fluctuation in principal value and liquidity.
 
   The Fund will invest in a diversified portfolio of short- and
   intermediate-term corporate, government, and mortgage-backed securities. The
   Fund may also invest in other types of securities such as bank obligations,
   collateralized mortgage obligations (CMOs), foreign securities, hybrids, and
   futures and options. Under normal circumstances, at least 65% of total assets
   will be invested in short-term bonds. The Fund's dollar-weighted average
   effective maturity will not exceed three years, and the Fund will not
   purchase any security whose effective maturity, average life, or tender date,
   measured from the date of settlement, exceeds seven years.
 
   Securities purchased by the Fund must be rated within the four highest credit
   categories (AAA, AA, A, BBB) by a national rating agency (or, if unrated, the
   T. Rowe Price equivalent). The investment-grade designation includes a range
   of securities from the highest rated to medium quality. Securities in the BBB
   category may be more susceptible to adverse economic conditions or changing
   circumstances and securities at the lower end of the BBB category have
   certain speculative characteristics.
 
   T. Rowe Price GNMA Fund
 
   The Fund's objective is a high level of current income consistent with
   maximum credit protection and moderate price fluctuation by investing
   exclusively in securities backed by the full faith and credit of the U.S.
   government and instruments involving these securities.
 
   The Fund will seek to fulfill its objective by investing primarily in
   mortgage-backed securities issued by the Government National Mortgage
   Association (GNMA), an agency of the Department of Housing and Urban
   Development (HUD). These securities represent pools of mortgage loans that
   are either insured by the Federal Housing Administration or guaranteed by the
   Veterans Administration. GNMA, in turn, guarantees the timely payment of
   interest and principal on its securities, a guarantee backed by the U.S.
   Treasury. The GNMA guarantee does not apply in any way to the price of GNMA
   securities or the Fund's share price, both of which will fluctuate with
   market conditions.
 
   The Fund can also purchase bills, notes, and bonds issued by the U.S.
   Treasury as well as related futures, other agency securities backed by the
   full faith and credit of the U.S. government, shares of an internal money
   fund, and securities involving GNMAs, such as collateralized mortgage
   obligations (CMOs) and stripped certificates (securities that receive only
   the interest or principal portion of the underlying mortgage payments).
 
  . Mortgage-Backed Securities Mortgage-backed securities are securities
   representing an interest in a pool of mortgages. Mortgage lenders pool
   individual home mortgages to back a certificate or bond, which is then sold
   to investors. The mortgages may be of a variety of types, including
   adjustable rate, conventional 30-year and 15-year fixed rate and graduated
   payment. Principal and interest payments generated by the underlying
   mortgages are passed through to the investors. This is in contrast to
   traditional bonds where principal is normally paid back at maturity in a lump
   sum. Unscheduled prepayments of principal shorten the securities' weighted
   average life and may lower their total return. (When a mortgage in the
   underlying mortgage pool is prepaid, an unscheduled principal prepayment is
   passed through to the Fund. This principal is returned to the Fund at par. As
   a result, if a mortgage security were trading at a premium, its total return
   would be lowered by prepayments, and if a mortgage security were trading at a
   discount, its total return would be increased by prepayments.) The value of
   these securities also may change because of changes in the market's
   perception of the creditworthiness of the federal agency that issued them. In
   addition, the mortgage securities market in general may be adversely affected
   by changes in governmental regulation or tax policies.
 
   T. Rowe Price New Income Fund, Inc.
 
   The Fund's objective is to provide the highest level of income consistent
   with the preservation of capital over time through investment primarily in
   marketable debt securities.
<PAGE>
 
   At least 80% of the Fund's total assets will be invested in income-producing,
   investment-grade instruments, including (but not limited to) U.S. government
   and agency obligations, mortgage-backed securities, corporate debt
   securities, asset-backed securities, bank obligations, collateralized
   mortgage obligations (CMOs), commercial paper, foreign securities, and
   others. There are no maturity restrictions on securities purchased by the
   Fund, but the Fund's dollar-weighted average maturity is generally expected
   to be between four and 15 years.
 
   Securities purchased by the Fund must be rated within the four highest credit
   categories (AAA, AA, A, BBB) by at least one established public rating agency
   (or, if unrated, must have a T. Rowe Price equivalent). The Fund will not
   purchase any security rated below investment grade (i.e., below BBB) by
   Standard & Poor's, Moody's, or Fitch Investor Services, except that with
   respect to 15% of its total assets the Fund may invest in "split-rated
   securities," which are securities that are rated within the four highest
   credit categories by at least one rating agency and below investment grade by
   another rating agency.
 
   Investment-grade securities include a range from the highest rated to medium
   quality. Securities in the BBB category may be more susceptible to adverse
   economic conditions or changing circumstances, and securities at the lower
   end of the BBB category have certain speculative characteristics.
 
   U.S. Treasury Long-Term Fund
 
   The Fund's investment objective is the highest level of current income
   consistent with maximum credit protection. It will invest at least 85% of
   total assets in U.S. Treasury securities and investments involving these
   securities. The remaining assets will be invested in other securities backed
   by the full faith and credit of the U.S. government and investments involving
   these securities. The Fund's dollar-weighted average maturity is expected to
   vary between 15 and 20 years, but may range from 10 to 30 years.
 
   T. Rowe Price High Yield Fund, Inc.
 
   The Fund's objective is high current income and, secondarily, capital
   appreciation.
 
   Under normal conditions, the Fund expects to invest at least 80% of its total
   assets in a widely diversified portfolio of high-yield bonds (so-called
   "junk" bonds) and income-producing convertible securities and preferred
   stocks. The Fund may also invest in a variety of other securities, including
   foreign securities, pay-in-kind bonds, private placements, bank loans, hybrid
   instruments, futures and options.
 
   
   The Fund's longer dollar-weighted average maturity (expected to be in the
   eight- to 12-year range) makes its price more sensitive to broad changes in
   interest rate movements than shorter-term bond funds. However, as explained
   earlier, interest rates are not the only, or necessarily the dominant,
   influence on the Fund's price.    
 
   Special Risks of Investing in Junk Bonds The following special considerations
   are additional risk factors associated with the Fund's investments in
   lower-rated debt securities.
 
  . Youth and Growth of the Lower-Rated Debt Securities Market The market for
   lower-rated debt securities is relatively new and its growth has paralleled a
   long economic expansion. Past experience may not, therefore, provide an
   accurate indication of future performance of this market, particularly during
   periods of economic recession. An economic downturn or increase in interest
   rates is likely to have a greater negative effect on this market, the value
   of lower-rated debt securities in the Fund's portfolio, the Fund's net asset
   value and the ability of the bonds' issuers to repay principal and interest,
   meet projected business goals and obtain additional financing than on
   higher-rated securities. These circumstances also may result in a higher
   incidence of defaults than with respect to higher-rated securities. An
   investment in this Fund is more speculative than investment in shares of a
   fund which invests only in higher-rated debt securities.
 
  . Sensitivity to Interest Rate and Economic Changes Prices of lower-rated debt
   securities may be more sensitive to adverse economic changes or corporate
   developments than higher-rated investments. Debt securities with longer
   maturities, which may have higher yields, may increase or decrease in value
   more than debt securities with shorter maturities. Market prices of
   lower-rated debt securities structured as zero coupon or pay-in-kind
   securities are affected to a greater extent by interest rate changes and may
   be more volatile than securities which pay interest periodically and in cash.
   Where it deems it appropriate and in the best interests of Fund
<PAGE>
 
   shareholders, the Fund may incur additional expenses to seek recovery on a
   debt security on which the issuer has defaulted and to pursue litigation to
   protect the interests of security holders of its portfolio companies.
 
  . Liquidity and Valuation Because the market for lower-rated securities may be
   thinner and less active than for higher-rated securities, there may be market
   price volatility for these securities and limited liquidity in the resale
   market. Nonrated securities are usually not as attractive to as many buyers
   as rated securities are, a factor which may make nonrated securities less
   marketable. These factors may have the effect of limiting the availability of
   the securities for purchase by the Fund and may also limit the ability of the
   Fund to sell such securities at their fair value either to meet redemption
   requests or in response to changes in the economy or the financial markets.
 
   Adverse publicity and investor perceptions, whether or not based on
   fundamental analysis, may decrease the values and liquidity of lower-rated
   debt securities, especially in a thinly traded market. To the extent the Fund
   owns or may acquire illiquid or restricted lower-rated securities, these
   securities may involve special registration responsibilities, liabilities and
   costs, and liquidity and valuation difficulties. Changes in values of debt
   securities which the Fund owns will affect its net asset value per share. If
   market quotations are not readily available for the Fund's lower-rated or
   nonrated securities, these securities will be valued by a method that the
   Fund's Board of Directors believes accurately reflects fair value. Judgment
   plays a greater role in valuing lower-rated debt securities than with respect
   to securities for which more external sources of quotations and last sale
   information are available.
 
  . Congressional Action New and proposed laws may have an impact on the market
   for lower-rated debt securities. T. Rowe Price is unable at this time to
   predict what effect, if any, any such legislation may have on the market for
   lower-rated debt securities.
 
  . Taxation Special tax considerations are associated with investing in
   lower-rated debt securities structured as zero coupon or pay-in-kind
   securities. The Fund accrues income on these securities prior to the receipt
   of cash payments. The Fund must distribute substantially all of its income to
   its shareholders to qualify for pass-through treatment under the tax laws and
   may, therefore, have to dispose of its portfolio securities to satisfy
   distribution requirements.
 
   T. Rowe Price Summit Cash Reserves Fund
 
   The Fund's objectives are preservation of capital, liquidity, and, consistent
   with these, the highest possible current income. The Fund invests in a
   diversified portfolio of U.S. dollar-denominated money market securities
   issued in the U.S. and abroad, and generally will not invest more than 5% of
   its total assets in securities of any one issuer. The Fund's yield will
   fluctuate in response to changes in interest rates, but the share price is
   managed to remain stable at $1.00. Unlike most bank accounts or certificates
   of deposit, the Fund is not insured or guaranteed by the U.S. government.
 
   The Fund invests at least 95% of its total assets in securities receiving the
   highest short-term credit rating assigned by at least two established rating
   agencies, by one rating agency if the security is rated by only one, or, if
   unrated, the equivalent rating as established by T. Rowe Price. The Fund's
   dollar-weighted average maturity will not exceed 90 days. It will purchase
   securities with maturities of 13 months or less.
 
   
                                Equity Funds    
 
   T. Rowe Price Growth & Income Fund, Inc.
 
   The Fund's objective is to provide long-term capital growth, a reasonable
   level of current income, and increasing future income through investments
   primarily in dividend-paying stocks.
 
   The Fund focuses on companies whose earnings are expected by T. Rowe Price to
   grow and support a growing dividend payment, as well as stocks that do not
   pay dividends currently but offer prospects of appreciation and future
   income.
 
   Most of the assets will be invested in U.S. common stocks. However, the Fund
   may also purchase other types of securities, for example, foreign securities,
   convertible stocks and bonds, and warrants, when considered
<PAGE>
 
   consistent with the Fund's investment objective and program. The portfolio
   manager may also engage in a variety of investment management practices, such
   as buying and selling futures and options.
 
   T. Rowe Price New Era Fund, Inc.
 
   The Fund's objective is long-term capital appreciation primarily through the
   common stocks of companies that own or develop natural resources and other
   basic commodities, and also through the stocks of selected nonresource growth
   companies.
 
   The Fund's primary focus will be on the common stocks of natural resource
   companies whose earnings and tangible assets could benefit from accelerating
   inflation. The Fund will also invest in selected nonresource growth companies
   with strong potential for earnings growth. T. Rowe Price believes that
   natural resource companies with the flexibility to adjust prices or control
   operating costs offer attractive opportunities for capital growth when
   inflation is rising. Income is not a consideration in the selection of
   securities.
 
   At least half of Fund assets will be invested in U.S. securities, principally
   common stocks, and the Fund may also invest up to 50% of its assets in
   foreign securities. In addition to common stocks, the Fund may purchase other
   types of securities, for example, convertible stocks and bonds, and warrants,
   when considered consistent with the Fund's investment objective. The Fund may
   also engage in a variety of investment management practices, such as buying
   and selling futures and options.
 
   The rate of earnings growth and stock prices of natural resource companies
   may follow irregular patterns since they are influenced strongly by the
   forces of nature, economic cycles, and international politics. For example,
   stock prices of mining and energy companies can be unpredictable and can fall
   steeply and rapidly. Companies owning or developing real estate could also be
   subject to earnings fluctuations related to the availability of money, the
   level of interest rates, and other factors.
 
   Although the Fund's foreign investments carry exposure to currency risk (the
   chance that a strong dollar will decrease returns for U.S. investors), many
   commodity markets are dollar-based, which cushions this risk. The Fund's
   investments in companies located in emerging markets are exposed to the risk
   of political and economic instability, prevalent in such countries.
 
   T. Rowe Price Growth Stock Fund, Inc.
 
   The Fund's objective is long-term growth of capital and, secondarily,
   increasing dividend income by investing primarily in common stocks of
   well-established growth companies.
 
   The Fund will invest at least 65% of total assets in the common stocks of a
   diversified group of growth companies. The companies in which the Fund
   invests normally (but not always) pay dividends that are generally expected
   to rise in future years as earnings increase.
 
   Most of the assets will be invested in U.S. common stocks. However, the Fund
   may also purchase other types of securities, for example, foreign securities,
   convertible stocks and bonds, and warrants, when considered consistent with
   the Fund's investment objective and program. The portfolio manager may also
   engage in a variety of investment management practices, such as buying and
   selling futures and options.
 
   T. Rowe Price New Horizons Fund, Inc.
 
   The Fund's investment objective is long-term growth of capital by investing
   primarily in common stocks of small, rapidly growing companies.
 
   The Fund will invest primarily in a diversified group of small, emerging
   growth companies. It will seek to invest early in the corporate life cycle,
   before a company becomes widely recognized by the investment community. The
   Fund may also invest in companies that offer the possibility of accelerating
   earnings growth because of rejuvenated management, new products, or
   structural changes in the economy. Total return will consist primarily of
   capital appreciation or depreciation.
 
   Most of the assets will be invested in U.S. common stocks. However, the Fund
   may also purchase other types of securities, for example, foreign securities,
   convertible stocks and bonds, and warrants, when considered
<PAGE>
 
   consistent with the Fund's investment objective and program. The portfolio
   manager may also engage in a variety of investment management practices, such
   as buying and selling futures and options.
 
   T. Rowe Price Mid-Cap Value Fund, Inc.
 
   The Fund's objective is to provide long-term capital appreciation by
   investing primarily in mid-size companies that appear to be undervalued.
 
   Reflecting a "value approach" to investing, the Fund will seek companies
   whose current stock prices do not appear to T. Rowe Price to reflect their
   underlying value as measured by assets, earnings, cash flow, or business
   franchises. The Fund will invest at least 65% of its assets in companies
   whose market capitalization (stock price multiplied by shares outstanding)
   falls between $300 million and $5 billion.
 
   Most of the assets will be invested in U.S. common stocks. However, the Fund
   may also purchase other types of securities, for example, foreign stocks,
   convertible securities, and warrants, when considered consistent with the
   Fund's investment objective and program. The Fund may also engage in a
   variety of investment management practices, such as buying and selling
   futures and options.
 
   T. Rowe Price Blue Chip Growth Fund, Inc.
 
   The Fund's primary objective is long-term growth of capital. Current income
   is a secondary objective, and many of the stocks in the Fund's portfolio are
   expected to pay dividends.
 
   The Fund will invest at least 65% of total assets in the common stocks of
   large and medium-sized blue chip companies, as defined by T. Rowe Price.
   These companies will be well established in their industries and have the
   potential for above-average growth in earnings.
 
   Most of the assets will be invested in U.S. common stocks. However, the Fund
   may also purchase other types of securities, for example, foreign securities,
   convertible stocks and bonds, and warrants, when considered consistent with
   the Fund's investment objective and program. The portfolio manager may also
   engage in a variety of investment management practices, such as buying and
   selling futures and options. Investments in convertible securities, preferred
   stocks, and debt securities are limited to 25% of total assets.
 
   T. Rowe Price Equity Income Fund
 
   The Fund's objective is to provide substantial dividend income as well as
   long-term capital appreciation through investments in common stocks of
   established companies.
 
   Under normal circumstances, the Fund will invest at least 65% of total assets
   in the common stocks of established companies paying above-average dividends.
   These companies are expected to have favorable prospects for dividend growth
   and capital appreciation, as determined by T. Rowe Price.
 
   Most of the assets will be invested in U.S. common stocks. However, the Fund
   may also purchase other types of securities, for example, foreign securities,
   convertible stocks and bonds, and warrants, when considered consistent with
   the Fund's investment objective and program. The portfolio manager may also
   engage in a variety of investment management practices, such as buying and
   selling futures and options.
 
   
                             International Funds    
 
   T. Rowe Price International Discovery Fund
 
   The Fund's objective is long-term growth of capital through investments
   primarily in common stocks of rapidly growing, small to medium-sized non-U.S.
   companies. Such companies may be found in developed and emerging markets.
   Traditionally, they are more dynamic and offer greater growth potential than
   larger companies, but they are generally riskier because they may have
   limited product lines, capital, and managerial resources. Their securities
   may trade less frequently and with greater price swings. Depending on
   conditions, the Fund's portfolio should be composed of at least 10 countries
   and 100 different companies.
<PAGE>
 
   T. Rowe Price European Stock Fund
 
   The Fund's objective is long-term growth of capital through investments
   primarily in common stocks of both large and small European companies.
   Current income is a secondary objective. The Fund seeks to take advantage of
   opportunities arising from such trends as privatization, the reduction of
   trade barriers, and the potential growth of the emerging economies of Eastern
   Europe. Normally, at least five countries will be represented in the
   portfolio, and investments may be made in any of the countries listed below,
   as well as others as their markets develop.
 
      Primary Emphasis France, Germany, Netherlands, Italy, Spain, Sweden,
      Switzerland, and United Kingdom.
 
      Others Austria, Belgium, Czech Republic, Denmark, Estonia, Finland,
      Greece, Hungary, Ireland, Israel, Latvia, Lithuania, Luxembourg,
      Norway, Poland, Portugal, Russia, Slovakia, and Turkey.
 
   T. Rowe Price New Asia Fund
 
   The Fund's objective is long-term growth of capital through investment in
   large and small companies domiciled or with primary operations in Asia,
   excluding Japan. The Fund may also invest in Pacific Rim countries such as
   Australia and New Zealand.
 
   Countries in which the Fund may invest include those in the following list as
   well as others in the region, such as China, Pakistan, and Vietnam, as their
   markets become more accessible. Investments will represent a minimum of five
   countries.
 
     Primary Emphasis Hong Kong, Indonesia, India, Malaysia, Philippines,
     Singapore, South Korea, Taiwan, Thailand.
 
   T. Rowe Price Japan Fund
 
   The Fund's objective is long-term growth of capital through investments in
   common stocks of large and small companies domiciled or with primary
   operations in Japan. Assets will normally be invested across a wide range of
   industries and companies (both small and large). Investors in a
   single-country fund are fully exposed to that country's economic, stock
   market, and currency cycles, which could increase both its risks and its
   potential rewards compared with a fund invested in several countries or
   regions.
 
   T. Rowe Price Emerging Markets Stock Fund
 
   The Fund's objective is long-term growth of capital through investment
   primarily in common stocks of large and small companies domiciled, or with
   primary operations, in emerging markets. An emerging market includes any
   country defined as emerging or developing by the International Bank for
   Reconstruction and Development (World Bank), the International Finance
   Corporation, or the United Nations. The Fund's investments are expected to be
   diversified geographically across emerging markets in Latin America, Asia,
   Europe, Africa, and the Middle East.
 
   Countries in which the Fund may invest are listed below and others will be
   added as opportunities develop:
 
      Asia China, Hong Kong, Indonesia, India, Korea, Malaysia, Pakistan,
      Philippines, Singapore, Sri Lanka, Taiwan, Thailand, and Vietnam.
 
      Latin America Argentina, Belize, Brazil, Chile, Colombia, Mexico,
      Panama, Peru, and Venezuela.
 
      Europe Austria, Croatia, Czech Republic, Estonia, Greece, Hungary,
      Latvia, Lithuania, Poland, Portugal, Romania, Russia, Slovakia, and
      Turkey.
 
      Africa and the Middle East Botswana, Egypt, Israel, Jordan,
      Mauritius, Morocco, Nigeria, South Africa, Tunisia, and Zimbabwe.
<PAGE>
 
   Emerging market investments rank high on the potential risk and reward
   spectrum because a developing country, much like an emerging-growth company,
   often advances in fits and starts toward developed status, and may or may not
   successfully achieve that status.
 
   T. Rowe Price Latin America Fund
 
   The Fund's objective is long-term growth of capital through investment
   primarily in common stocks of companies domiciled, or with primary
   operations, in Latin America. The Fund expects to invest primarily in Mexico,
   Brazil, Chile, Argentina, Venezuela, Peru, and other markets as opportunities
   arise and conditions permit, including, but not limited to Belize, Colombia,
   Ecuador, and Guatemala. The portfolio is normally expected to invest in at
   least four countries.
 
   The Fund expects to make substantial investments (at times more than 25% of
   total assets) in the telephone companies of various Latin American countries.
   These utilities play a critical role in a country's economic development, but
   their stocks could be adversely affected if trends favoring development were
   to be reversed.
 
   Because Latin America includes many less-developed countries with legacies of
   political instability, investors should read the section on major risks of
   international investing, particularly the discussion of "political and
   economic factors."
 
   T. Rowe Price International Bond Fund
 
   The Fund's objective is to provide high current income and capital
   appreciation by investing in high-quality, nondollar-denominated government
   and corporate bonds outside the U.S. The Fund also seeks to moderate price
   fluctuation by actively managing its maturity structure and currency
   exposure. The Fund will invest at least 65% of its assets in high-quality
   bonds but may invest up to 20% of assets in below investment-grade, high-risk
   bonds, including bonds in default or those with the lowest rating. Up to 20%
   of the Fund's assets may be invested in foreign bonds denominated in dollars,
   such as Brady and other emerging market bonds.
 
   Rowe Price-Fleming International, Inc. ("Price-Fleming"), the Fund's
   investment manager, bases its investment decisions on fundamental market
   factors, currency trends, and credit quality. The Fund generally invests in
   countries where the combination of fixed income returns and currency exchange
   rates appears attractive, or, if the currency trend is unfavorable, where the
   currency risk can be minimized through hedging.
 
   Although the Fund expects to maintain an intermediate to long weighted
   average maturity, it has no maturity restrictions on the overall portfolio or
   on individual securities. Normally, the Fund does not hedge its foreign
   currency exposure back to the dollar, nor involve more than 50% of total
   assets in cross hedging transactions. Therefore, changes in foreign interest
   rates and currency exchange rates are likely to have a significant impact on
   total return and the market value of portfolio securities. Such changes
   provide greater opportunities for capital gains and greater risks of capital
   loss. Price-Fleming attempts to reduce these risks through diversification
   among foreign securities and active management of maturities and currency
   exposures.
 
   T. Rowe Price Emerging Markets Bond Fund
 
   The Fund's objective is to provide high income and capital appreciation. The
   Fund invests at least 65% (and potentially all) of its total assets in the
   government and corporate debt securities of emerging nations. Since these
   countries are less developed and their bonds carry a greater risk of default,
   such bonds are typically below investment grade and would be considered junk
   bonds in the U.S.
 
   The Fund may invest in the lowest-rated bonds, including those in default.
   While these investments may offer significantly greater total returns than
   higher-quality bonds of developed foreign markets, they entail a higher
   degree of risk and are subject to sharp price declines.
 
   There are no maturity restrictions on the Fund. Its weighted average maturity
   normally ranges between five and 10 years, but may vary substantially because
   of market conditions. Under normal circumstances, most of the Fund's total
   assets are expected to be denominated in U.S. dollars, and the Fund will not
   usually hedge foreign currency holdings back to U.S. dollar. Currency
   fluctuations can have a significant impact on the value of the Fund's
   holdings.
<PAGE>
 
   T. Rowe Price International Stock Fund
 
   The Fund's objective is long-term growth of capital through investments
   primarily in common stocks of established, non-U.S. companies. The Fund
   expects to invest substantially all of its assets outside the U.S. and to
   diversify broadly among countries throughout the world - developed and
   emerging.
 
   The Fund expects to invest substantially all of its assets in common stocks.
   However, the Fund may also invest in a variety of other equity-related
   securities, such as preferred stocks, warrants and convertible securities, as
   well as corporate and governmental debt securities, when considered
   consistent with the Fund's investment objective and program. The Fund may
   also engage in a variety of investment management practices, such as buying
   and selling futures and options. Under normal market conditions, the Fund's
   investment in securities other than common stocks is limited to no more than
   35% of total assets. However, for temporary defensive purposes, the Fund may
   invest all or a significant portion of its assets in U.S. government and
   corporate debt obligations. The Fund will not purchase any debt security
   which at the time of purchase is rated below investment grade. This would not
   prevent the Fund from retaining a security downgraded to below investment
   grade after purchase.
 
   Risk Factors of Foreign Investing There are special risks in foreign
   investing. Certain of these risks are inherent in any international mutual
   fund while others relate more to the countries in which the Fund will invest.
   Many of the risks are more pronounced for investments in developing or
   emerging countries, such as many of the countries of Asia, Latin America,
   Eastern Europe, Russia, Africa and the Middle East. Although there is no
   universally accepted definition, a developing country is generally considered
   to be a country which is in the initial stages of its industrialization cycle
   with a per capita gross national product of less than $8,000.
 
  . Political and Economic Factors Individual foreign economies of certain
   countries differ favorably or unfavorably from the United States' economy in
   such respects as growth of gross national product, rate of inflation, capital
   reinvestment, resource self-sufficiency and balance of payments position. The
   internal politics of certain foreign countries are not as stable as in the
   United States. For example, in 1991, the existing government in Thailand was
   overthrown in a military coup. In 1992, there were two military coup attempts
   in Venezuela and in 1992 the President of Brazil was impeached. In 1994-1995,
   the Mexican peso plunged in value setting off a severe crisis in the Mexican
   economy. Asia is still coming to terms with its own crisis and recessionary
   conditions sparked off by widespread currency weakness in late 1997. In
   addition, significant external political risks currently affect some foreign
   countries. Both Taiwan and China still claim sovereignty of one another and
   there is a demilitarized border and hostile relations between North and South
   Korea.
 
   Governments in certain foreign countries continue to participate to a
   significant degree, through ownership interest or regulation, in their
   respective economies. Action by these governments could have a significant
   effect on market prices of securities and payment of dividends. The economies
   of many foreign countries are heavily dependent upon international trade and
   are accordingly affected by protective trade barriers and economic conditions
   of their trading partners. The enactment by these trading partners of
   protectionist trade legislation could have a significant adverse effect upon
   the securities markets of such countries.
 
  . Currency Fluctuations The international funds invest in securities
   denominated in various currencies. Accordingly, a change in the value of any
   such currency against the U.S. dollar will result in a corresponding change
   in the U. S. dollar value of the Fund's assets denominated in that currency.
   Such changes will also affect the Fund's income. Generally, when a given
   currency appreciates against the dollar (the dollar weakens) the value of the
   Fund's securities denominated in that currency will rise. When a given
   currency depreciates against the dollar (the dollar strengthens) the value of
   the Fund's securities denominated in that currency would be expected to
   decline.
 
  . Investment and Repatriation of Restrictions Foreign investment in the
   securities markets of certain foreign countries is restricted or controlled
   in varying degrees. These restrictions limit at times and preclude investment
   in certain of such countries and increase the cost and expenses of the
   international funds. Investments by foreign investors are subject to a
   variety of restrictions in many developing countries. These restrictions may
   take the form of prior governmental approval, limits on the amount or type of
   securities held by foreigners, and limits on the types of companies in which
   foreigners may invest. Additional or different
<PAGE>
 
   restrictions may be imposed at any time by these or other countries in which
   the international funds invest. In addition, the repatriation of both
   investment income and capital from several foreign countries is restricted
   and controlled under certain regulations, including in some cases the need
   for certain government consents. For example, capital invested in Chile
   normally cannot be repatriated for one year.
 
  . Market Characteristics It is contemplated that most foreign securities will
   be purchased in over-the-counter markets or on stock exchanges located in the
   countries in which the respective principal offices of the issuers of the
   various securities are located, if that is the best available market.
   Investments in certain markets may be made through ADRs traded in the United
   States. Foreign stock markets are generally not as developed or efficient as,
   and more volatile than, those in the United States. While growing in volume,
   they usually have substantially less volume than U.S. markets and the Fund's
   portfolio securities may be less liquid and subject to more rapid and erratic
   price movements than securities of comparable U.S. companies. Equity
   securities may trade at price/earnings multiples higher than comparable
   United States securities and such levels may not be sustainable. Commissions
   on foreign stocks are generally higher than commissions on United States
   exchanges, and while there is an increasing number of overseas stock markets
   that have adopted a system of negotiated rates, a number are still subject to
   an established schedule of minimum commission rates. There is generally less
   government supervision and regulation of foreign stock exchanges, brokers,
   and listed companies than in the United States. Moreover, settlement
   practices for transactions in foreign markets may differ from those in United
   States markets. Such differences include delays beyond periods customary in
   the United States and practices, such as delivery of securities prior to
   receipt of payment, which increase the likelihood of a "failed settlement."
   Failed settlements can result in losses to the Fund.
 
  . Investment Funds The international funds may invest in investment funds
   which have been authorized by the governments of certain countries
   specifically to permit foreign investment in securities of companies listed
   and traded on the stock exchanges in these respective countries. The
   international funds' investment in these funds is subject to the provisions
   of the 1940 Act. If the international funds invest in such investment funds,
   the Fund's shareholders will bear not only their proportionate share of the
   expenses of the Fund (including operating expenses and the fees of the
   investment manager), but also will bear indirectly similar expenses of the
   underlying investment funds. In addition, the securities of these investment
   funds may trade at a premium over their net asset value.
 
  . Information and Supervision There is generally less publicly available
   information about foreign companies comparable to reports and ratings that
   are published about companies in the United States. Foreign companies are
   also generally not subject to uniform accounting, auditing and financial
   reporting standards, practices, and requirements comparable to those
   applicable to United States companies. It also is often more difficult to
   keep currently informed of corporate actions which affect the prices of
   portfolio securities.
 
  . Taxes The dividends and interest payable on certain of the international
   funds' foreign portfolio securities may be subject to foreign withholding
   taxes, thus reducing the net amount of income available for distribution to
   the Fund's shareholders.
 
  . Other With respect to certain foreign countries, especially developing and
   emerging ones, there is the possibility of adverse changes in investment or
   exchange control regulations, expropriation or confiscatory taxation,
   limitations on the removal of Funds or other assets of the Funds, political
   or social instability, or diplomatic developments which could affect
   investments by U.S. persons in those countries.
 
  . Eastern Europe and Russia Changes occurring in Eastern Europe and Russia
   today could have long-term potential consequences. As restrictions fall, this
   could result in rising standards of living, lower manufacturing costs,
   growing consumer spending, and substantial economic growth. However,
   investment in the countries of Eastern Europe and Russia is highly
   speculative at this time. Political and economic reforms are too recent to
   establish a definite trend away from centrally planned economies and
   state-owned industries. In many of the countries of Eastern Europe and
   Russia, there is no stock exchange or formal market for securities. Such
   countries may also have government exchange controls, currencies with no
   recognizable market value relative to the established currencies of western
   market economies, little or no experience in trading in securities, no
   financial reporting standards, a lack of a banking and securities
   infrastructure to handle such trading, and a
<PAGE>
 
   legal tradition which does not recognize rights in private property. In
   addition, these countries may have national policies which restrict
   investments in companies deemed sensitive to the country's national interest.
   Further, the governments in such countries may require governmental or
   quasi-governmental authorities to act as custodian of the Fund's assets
   invested in such countries, and these authorities may not qualify as a
   foreign custodian under the Investment Company Act of 1940 and exemptive
   relief from such Act may be required. All of these considerations are among
   the factors which could cause significant risks and uncertainties to
   investment in Eastern Europe and Russia. The Fund will only invest in a
   company located in, or a government of, Eastern Europe and Russia, if it
   believes the potential return justifies the risk.
 
  . Latin America
 
   Inflation Most Latin American countries have experienced, at one time or
   another, severe and persistent levels of inflation, including, in some cases,
   hyperinflation. This has, in turn, led to high interest rates, extreme
   measures by governments to keep inflation in check, and a generally
   debilitating effect on economic growth. Although inflation in many countries
   has lessened, there is no guarantee it will remain at lower levels.
 
   Political Instability The political history of certain Latin American
   countries has been characterized by political uncertainty, intervention by
   the military in civilian and economic spheres, and political corruption. Such
   developments, if they were to reoccur, could reverse favorable trends toward
   market and economic reform, privatization, and removal of trade barriers, and
   result in significant disruption in securities markets.
 
   Foreign Currency Certain Latin American countries may have managed currencies
   which are maintained at artificial levels to the U. S. dollar rather than at
   levels determined by the market. This type of system can lead to sudden and
   large adjustments in the currency which, in turn, can have a disruptive and
   negative effect on foreign investors. For example, in late 1994 the value of
   the Mexican peso lost more than one-third of its value relative to the
   dollar. Certain Latin American countries also restrict the free conversion of
   their currency into foreign currencies, including the U.S. dollar. There is
   no significant foreign exchange market for many currencies and it would, as a
   result, be difficult for the Fund to engage in foreign currency transactions
   designed to protect the value of the Fund's interests in securities
   denominated in such currencies.
 
   Sovereign Debt A number of Latin American countries are among the largest
   debtors of developing countries. There have been moratoria on, and
   reschedulings of, repayment with respect to these debts. Such events can
   restrict the flexibility of these debtor nations in the international markets
   and result in the imposition of onerous conditions on their economies.
 
  . Japan
 
   
   The Japan Fund's concentration of its investments in Japan means the Fund
   will be more dependent on the investment considerations discussed above and
   may be more volatile than a fund which is broadly diversified geographically.
   To the extent any of the other funds also invest in Japan, such investments
   will be subject to these same factors. Additional factors relating to Japan
   include the following:    
 
   Japan has experienced earthquakes and tidal waves of varying degrees of
   severity, and the risks of such phenomena, and damage resulting therefrom,
   continue to exist. Japan also has one of the world's highest population
   densities. A significant percentage of the total population of Japan is
   concentrated in the metropolitan areas of Tokyo, Osaka and Nagoya.
 
   Energy Japan has historically depended on oil for most of its energy
   requirements. Almost all of its oil is imported, the majority from the Middle
   East. In the past, oil prices have had a major impact on the domestic
   economy, but more recently Japan has worked to reduce its dependence on oil
   by encouraging energy conservation and use of alternative fuels. In addition,
   a restructuring of industry, with emphasis shifting from basic industries to
   processing and assembly type industries, has contributed to the reduction of
   oil consumption. However, there is no guarantee this favorable trend will
   continue.
 
   Foreign Trade Overseas trade is important to Japan's economy. Japan has few
   natural resources and must export to pay for its imports of these basic
   requirements. Because of the concentration of Japanese exports in highly
   visible products such as automobiles, machine tools and semiconductors and
   the large trade surpluses
<PAGE>
 
   ensuing therefrom, Japan has had difficult relations with its trading
   partners, particularly the U.S. It is possible that trade sanctions or other
   protectionist measures could impact Japan adversely in both the short- and
   long-term.
 
  . Costs Investors should understand that the expense ratios of the Fund can be
   expected to be higher than investment companies investing in domestic
   securities since the cost of maintaining the custody of foreign securities
   and the rate of advisory fees paid by the Fund is higher.
 
  . Small Companies Small companies may have less experienced management and
   fewer management resources than larger firms. A smaller company may have
   greater difficulty obtaining access to capital markets, and may pay more for
   the capital it obtains. In addition, smaller companies are more likely to be
   involved in fewer market segments, making them more vulnerable to any
   downturn in a given segment. Some of these factors may also apply, to a
   lesser extent, to medium size companies. Some of the smaller companies in
   which the Fund will invest may be in major foreign markets; others may be
   leading companies in emerging countries outside the major foreign markets.
   Securities analysts generally do not follow such securities, which are seldom
   held outside of their respective countries and which may have prospects for
   long-term investment returns superior to the securities of well-established
   and well-known companies. Direct investment in such securities may be
   difficult for United States investors because, among other things,
   information relating to such securities is often not readily available. Of
   course, there are also risks associated with such investments, and there is
   no assurance that such prospects will be realized.
 
   Asia (ex-Japan)
   Political Instability The political history of certain Asian countries has
   been characterized by political uncertainty, intervention by the military in
   civilian and economic spheres, and political corruption. Such developments,
   if they continue to occur, could reverse favorable trends toward market and
   economic reform, privatization and removal of trade barriers and result in
   significant disruption in securities markets.
 
   Foreign Currency Certain Asian countries may have managed currencies which
   are maintained at artificial levels to the U.S. dollar rather than at levels
   determined by the market. This type of system can lead to sudden and large
   adjustments in the currency which, in turn, can have a disruptive and
   negative effect on foreign investors. For example, in 1997 the Thai baht lost
   46.75% of its value against the U.S. dollar. Certain Asian countries also may
   restrict the free conversion of their currency into foreign currencies,
   including the U.S. dollar. There is no significant foreign exchange market
   for certain currencies and it would, as a result, be difficult for the Fund
   to engage in foreign currency transactions designed to protect the value of
   the Fund's interests in securities denominated in such currencies.
 
   Debt A number of Asian companies are highly dependent on foreign loans for
   their operation. In 1997, several Asian countries were forced to negotiate
   loans from the IMF and others that impose strict repayment term schedules and
   require significant economic and financial restructuring.
 
 
                               Types of Securities
 
   Set forth below is additional information about certain of the investments
   described in the Fund's prospectus.
 
 
                              Repurchase Agreements
 
   The Fund may enter into a repurchase agreement through which an investor
   (such as the Fund) purchases a security (known as the "underlying security")
   from a well-established securities dealer or a bank that is a member of the
   Federal Reserve System. Any such dealer or bank will be on T. Rowe Price's
   approved list and have a credit rating with respect to its short-term debt of
   at least A1 by Standard & Poor's Corporation, P1 by Moody's Investors
   Services, Inc., or the equivalent rating by T. Rowe Price. At that time, the
   bank or securities dealer agrees to repurchase the underlying security at the
   same price, plus specified interest. Repurchase agreements are generally for
   a short period of time, often less than a week. Repurchase agreements which
   do not provide for payment within seven days will be treated as illiquid
   securities. The Fund will only enter into repurchase agreements where (i) the
   underlying securities are of the type (excluding maturity limitations) which
   the Fund's investment guidelines would allow it to purchase directly, (ii)
   the market value of the underlying security, including interest accrued, will
   be at all times equal to or exceed the value of the
<PAGE>
 
   repurchase agreement, and (iii) payment for the underlying security is made
   only upon physical delivery or evidence of book-entry transfer to the account
   of the custodian or a bank acting as agent. In the event of a bankruptcy or
   other default of a seller of a repurchase agreement, the Fund could
   experience both delays in liquidating the underlying security and losses,
   including: (a) possible decline in the value of the underlying security
   during the period while the Fund seeks to enforce its rights thereto; (b)
   possible subnormal levels of income and lack of access to income during this
   period; and (c) expenses of enforcing its rights.
 
 
                               Hybrid Instruments
 
   Hybrid Instruments (a type of potentially high-risk derivative) have been
   developed and combine the elements of futures contracts or options with those
   of debt, preferred equity, or a depository instrument (hereinafter "Hybrid
   Instruments"). Often these Hybrid Instruments are indexed to the price of a
   commodity, particular currency, or a domestic or foreign debt or equity
   securities index. Thus, Hybrid Instruments may take a variety of forms,
   including, but not limited to, debt instruments with interest or principal
   payments or redemption terms determined by reference to the value of a
   currency or commodity or securities index at a future point in time,
   preferred stock with dividend rates determined by reference to the value of a
   currency, or convertible securities with the conversion terms related to a
   particular commodity.
 
   
   The risks of investing in Hybrid Instruments reflect a combination of the
   risks of investing in securities, options, futures and currencies, including
   volatility and lack of liquidity. Reference is also made to the discussion of
   futures, options, and forward contracts herein for a discussion of the risks
   associated with such investments. Further, the prices of the Hybrid
   Instrument and the related commodity or currency may not move in the same
   direction or at the same time. Hybrid Instruments may bear interest or pay
   preferred dividends at below market (or even relatively nominal) rates.
   Alternatively, Hybrid Instruments may bear interest at above market rates but
   bear an increased risk of principal loss (or gain). In addition, because the
   purchase and sale of Hybrid Instruments could take place in an
   over-the-counter market or in a private transaction between the Fund and the
   seller of the Hybrid Instrument, the creditworthiness of the contra party to
   the transaction would be a risk factor which the Fund would have to consider.
   Hybrid Instruments also may not be subject to regulation of the Commodities
   Futures Trading Commission ("CFTC"), which generally regulates the trading of
   commodity futures by U.S. persons, the SEC, which regulates the offer and
   sale of securities by and to U.S. persons, or any other governmental
   regulatory authority.    
 
 
                        Illiquid or Restricted Securities
 
   Restricted securities may be sold only in privately negotiated transactions
   or in a public offering with respect to which a registration statement is in
   effect under the Securities Act of 1933 (the "1933 Act"). Where registration
   is required, the Fund may be obligated to pay all or part of the registration
   expenses, and a considerable period may elapse between the time of the
   decision to sell and the time the Fund may be permitted to sell a security
   under an effective registration statement. If, during such a period, adverse
   market conditions were to develop, the Fund might obtain a less favorable
   price than prevailed when it decided to sell. Restricted securities will be
   priced at fair value as determined in accordance with procedures prescribed
   by the Fund's Board of Directors. If, through the appreciation of illiquid
   securities or the depreciation of liquid securities, the Fund should be in a
   position where more than 15% of the value of its net assets is invested in
   illiquid assets, including restricted securities, the Fund will take
   appropriate steps to protect liquidity.
 
   Notwithstanding the above, the Fund may purchase securities which, while
   privately placed, are eligible for purchase and sale under Rule 144A under
   the 1933 Act. This rule permits certain qualified institutional buyers, such
   as the Fund, to trade in privately placed securities even though such
   securities are not registered under the 1933 Act. T. Rowe Price and
   Price-Fleming, under the supervision of the Fund's Board of Directors, will
   consider whether securities purchased under Rule 144A are illiquid and thus
   subject to the Fund's restriction of investing no more than 15% of its net
   assets in illiquid securities. A determination of whether a Rule 144A
   security is liquid or not is a question of fact. In making this
   determination, T. Rowe Price and Price-Fleming will consider the trading
   markets for the specific security taking into account the unregistered nature
   of a Rule 144A security. In addition, Price-Fleming could consider the (1)
   frequency of trades and quotes, (2) number of dealers and potential
   purchases, (3) dealer undertakings to make a market, and (4) the
<PAGE>
 
   nature of the security and of marketplace trades (e.g., the time needed to
   dispose of the security, the method of soliciting offers, and the mechanics
   of transfer). The liquidity of Rule 144A securities would be monitored and,
   if as a result of changed conditions it is determined that a Rule 144A
   security is no longer liquid, the Fund's holdings of illiquid securities
   would be reviewed to determine what, if any, steps are required to assure
   that the Fund does not invest more than 15% of its net assets in illiquid
   securities. Investing in Rule 144A securities could have the effect of
   increasing the amount of the Fund's assets invested in illiquid securities if
   qualified institutional buyers are unwilling to purchase such securities.
 
 
                                    Warrants
 
   The Fund may acquire warrants. Warrants are pure speculation in that they
   have no voting rights, pay no dividends, and have no rights with respect to
   the assets of the corporation issuing them. Warrants basically are options to
   purchase equity securities at a specific price valid for a specific period of
   time. They do not represent ownership of the securities, but only the right
   to buy them. Warrants differ from call options in that warrants are issued by
   the issuer of the security which may be purchased on their exercise, whereas
   call options may be written or issued by anyone. The prices of warrants do
   not necessarily move parallel to the prices of the underlying securities.
 
   There are, of course, other types of securities that are, or may become
   available, which are similar to the foregoing and the Funds may invest in
   these securities.
 
 
                         InterFund Borrowing and Lending
 
   Subject to approval by the Securities and Exchange Commission, and certain
   state regulatory agencies, each Fund may borrow funds from, and certain of
   the Underlying Price Funds may make loans to, and borrow funds from, other
   Price Funds. These Funds have no current intention of engaging in these
   practices at this time.
 
 
 
 SPECIAL CONSIDERATIONS
 -------------------------------------------------------------------------------
   Prospective investors should consider that certain underlying price funds
   (the "Price Funds") may engage in the following:
 
   Foreign Currency Transactions Enter into foreign currency transactions. Since
   investments in foreign companies will usually involve currencies of foreign
   countries, and the International Bond and International Stock Funds, as well
   as certain other Price Funds, will hold Funds in bank deposits in foreign
   custodians during the completion of investment programs, the value of the
   assets of the Price Funds as measured in U.S. dollars may be affected
   favorably or unfavorably by changes in foreign currency exchange rates and
   exchange control regulations, and these Price Funds may incur costs in
   connection with conversions between various currencies. The Price Funds will
   generally conduct their foreign currency exchange transactions either on a
   spot (i.e., cash) basis at the prevailing rate in the foreign currency
   exchange market, or through entering into forward contracts to purchase or
   sell foreign currencies. The Price Funds will generally not enter into a
   forward contract with a term of greater than one year. Although foreign
   currency transactions will be used primarily to protect the Price Funds from
   adverse currency movements, they also involve the risk that anticipated
   currency movements will not be accurately predicted.
 
   Lending Portfolio Securities Lend portfolio securities for the purpose of
   realizing additional income. The Price Funds may lend securities to
   broker-dealers or institutional investors. Any such loan will be continuously
   secured by collateral at least equal to the value of the security loaned.
   Such lending could result in delays in receiving additional collateral or in
   the recovery of the securities or possible loss of rights in the collateral
   should the borrower fail financially.
 
   Futures Contracts and Options (types of potentially high-risk derivatives)
   Enter into interest rate, stock index or currency futures contracts. Certain
   Price Funds may enter into such contracts (or options thereon), or a
   combination of such contracts, (1) as a hedge against changes in prevailing
   levels of interest rates, price
<PAGE>
 
   movements or currency exchange rates in the Price Funds' portfolios in order
   to establish more definitely the effective return on securities or currencies
   held or intended to be acquired by such Price Funds; (2) as an efficient
   means of adjusting the Price Funds' exposure to the markets; or (3) to adjust
   the duration of the Price Funds' portfolios. Initial margin deposits and
   premiums on options used for non-hedging purposes will not equal more than 5%
   of each Price Fund's net asset value. Certain Price Funds may also purchase
   and sell call and put options on securities, currencies and financial and
   stock indices. The aggregate market value of each Fund's currencies or
   portfolio securities covering call or put options will not exceed 25% of a
   Fund's net assets. Futures contracts and options can be highly volatile and
   could result in reduction of a Price Fund's total return and a Price Fund's
   attempt to use such investments for hedging purposes may not be successful.

 INVESTMENT RESTRICTIONS
 -------------------------------------------------------------------------------
   Fundamental policies may not be changed without the approval of the lesser of
   (1) 67% of the Fund's shares present at a meeting of shareholders if the
   holders of more than 50% of the outstanding shares are present in person or
   by proxy or (2) more than 50% of a Fund's outstanding shares. Other
   restrictions in the form of operating policies are subject to change by the
   Fund's Board of Directors without shareholder approval. Any investment
   restriction which involves a maximum percentage of securities or assets shall
   not be considered to be violated unless an excess over the percentage occurs
   immediately after, and is caused by, an acquisition of securities or assets
   of, or borrowings by, the Fund. Calculation of the Fund's total assets for
   compliance with any of the following fundamental or operating policies or any
   other investment restrictions set forth in the Fund's prospectus or Statement
   of Additional Information will not include cash collateral held in connection
   with securities lending activities.
 
 
                              Fundamental Policies
 
   As a matter of fundamental policy, the Fund may not:
 
   
   (1) Borrowing Borrow money, except the Fund may borrow from banks or other
       Price Funds as a temporary measure for extraordinary or emergency
       purposes, and then only in amounts not exceeding 30% of its total assets
       valued at market. The Fund will not borrow in order to increase income
       (leveraging), but only to facilitate redemption requests which might
       otherwise require untimely disposition of portfolio securities. Interest
       paid on any such borrowings will reduce net investment income;    
 
   (2) Commodities (a) Spectrum Growth and Spectrum Income Funds may not
       purchase or sell commodities or commodity or futures contracts;
 
       (b)Spectrum International Fund may not purchase or sell physical
       commodities; except that it may enter into futures contracts and options
       thereon.
 
   (3) Loans Make loans, although the Funds may purchase money market securities
       and enter into repurchase agreements;
 
   (4) Margin Purchase securities on margin, except for use of short-term credit
       necessary for clearance of purchases of portfolio securities;
 
   (5) Mortgaging Mortgage, pledge, hypothecate or, in any manner, transfer any
       security owned by the Funds as security for indebtedness except as may be
       necessary in connection with permissible borrowings, in which event such
       mortgaging, pledging, or hypothecating may not exceed 30% of each Fund's
       total assets, valued at market;
 
   (6) Real Estate Purchase or sell real estate, including limited partnership
       interests therein, unless acquired as a result of ownership of securities
       or other instruments (although each Fund may purchase money
<PAGE>
 
       market securities secured by real estate or interests therein, or issued
       by companies or investment trusts which invest in real estate or
       interests therein);
 
   (7) Senior Securities Issue senior securities;
 
   (8) Short Sales Effect short sales of securities; or
 
   (9) Underwriting Underwrite securities issued by other persons, except to the
       extent that the Fund may be deemed to be an underwriter within the
       meaning of the Securities Act of 1933 in connection with the purchase and
       sale of its portfolio securities in the ordinary course of pursuing its
       investment program.
 
 
                               Operating Policies
 
   As a matter of operating policy, the Fund may not:
 
   (1) Control of Portfolio Companies Invest in companies for the purpose of
       exercising management or control;
 
   (2) Illiquid Securities Purchase illiquid securities if, as a result, more
       than 15% of its net assets would be invested in such securities;
 
   (3) Oil and Gas Programs Purchase participations or other direct interests
       in, or enter into leases with respect to, oil, gas, or other mineral
       exploration or development programs if, as a result thereof, more than 5%
       of the value of the total assets of the Fund would be invested in such
       programs;
 
   (4) Options Invest in options;
 
   (5) Futures Spectrum Income and Spectrum Growth Funds may not invest in
       futures. Spectrum International Fund, though it has no intention at this
       time of investing in futures, reserves the right to do so in the future;
 
   (6) Forward Currency Contracts None of the Funds has the intention of
       investing in forward currency contracts at this time. However, they all
       reserve the right to do so at some point in the future; or
 
   (7) Warrants Invest in warrants.
 
   Pursuant to an Exemptive Order issued by the Securities and Exchange
   Commission (Investment Company Act Release No. IC-21425, October 18, 1995):
   (i) there is no limit on the amount the Fund may own of the total outstanding
   voting securities of registered investment companies which are members of the
   T. Rowe Price family of funds, (ii) each Fund, in accordance with its
   prospectus, may invest more than 5% of its assets in any one such investment
   company, and (iii) each Fund may invest more than 10% of its assets,
   collectively, in registered investment companies which are members of the T.
   Rowe Price family of funds.
 
   Because of their investment objectives and policies, the Funds will each
   concentrate more than 25% of their assets in the mutual fund industry. In
   accordance with the Funds' investment programs set forth in the prospectus,
   each of the Funds may invest more than 25% of its assets in certain of the
   Underlying Price Funds. However, each of the Underlying Price Funds in which
   each Fund will invest (other than New Income, Short-Term Bond, High Yield,
   Latin America, and International Bond Funds) will not concentrate more than
   25% of its total assets in any one industry. The Latin America Fund expects
   to make substantial investments in the telephone companies of various Latin
   America countries (at times more than 25% of total assets). The New Income
   and Short-Term Bond Funds will, under certain conditions, invest up to 50% of
   their assets in any one of the following industries: gas, utility, gas
   transmission utility, electric utility, telephone utility and petroleum. The
   Short-Term Bond, International Bond, and High Yield Funds will each normally
   concentrate 25% or more of their assets in the securities of the banking
   industry when their position in issues maturing in one year or less equals
   35% or more of their total assets.

 MANAGEMENT OF FUNDS    
 -------------------------------------------------------------------------------
   The management of each Fund's business and affairs is the responsibility of
   the Board of Directors for Spectrum Fund. In exercising their
   responsibilities, the Board, among other things, will refer to the Special
   Servicing Agreement (see page 20 and 21) and policies and guidelines included
   in an Application for an Exemptive Order (and accompanying Notice and Order
   issued by the Commission). A majority of Spectrum Fund's directors will be
   non-interested persons as defined in Section 2(a)(19) of the 1940 Act.
   However, the interested directors and the officers of Spectrum Fund, T. Rowe
   Price and Rowe Price-Fleming also serve in similar positions with most of the
   Underlying Price Funds. Thus, if the interests of a Fund and the Underlying
   Price Funds were ever to become divergent, it is possible that a conflict of
   interest could arise and affect how this latter group of persons fulfill
   their fiduciary duties to that Fund and the Underlying Price Funds. The
   directors of Spectrum Fund believe they have structured each Fund to avoid
   these concerns. However, conceivably, a situation could occur where proper
   action for Spectrum Fund or the Growth Fund, Income Fund or International
   Fund separately, could be adverse to the interests of an Underlying Price
   Fund, or the reverse could occur. If such a possibility arises, the directors
   and officers of the affected Funds and T. Rowe Price will carefully analyze
   the situation and take all steps they believe reasonable to minimize and,
   where possible, eliminate the potential conflict. Moreover, limitations on
   aggregate investments in the Underlying Price Funds and other restrictions
   have been adopted by Spectrum Fund to minimize this possibility, and close
   and continuous monitoring will be exercised to avoid, insofar as possible,
   these concerns.
 
   The officers and directors of Spectrum Fund are listed below. Unless
   otherwise noted, the address of each is 100 East Pratt Street, Baltimore,
   Maryland 21202. Except as indicated, each has been an employee of T. Rowe
   Price for more than five years. In the list below, Spectrum Fund's directors
   who are considered "interested persons" of T. Rowe Price, Rowe Price-Fleming,
   or the Fund as defined under Section 2(a)(19) of the Investment Company Act
   of 1940 are noted with an asterisk (*). Mr. Riepe is referred to as an inside
   director by virtue of his directorship and employment by T. Rowe Price.

 INVESTMENT MANAGEMENT SERVICES
 -------------------------------------------------------------------------------
   The business of Spectrum Fund will be conducted by its officers, directors,
   and investment manager in accordance with policies and guidelines set up by
   Spectrum Fund's directors which were included in the Exemptive Order issued
   by the Securities and Exchange Commission (Investment Company Act Release No.
   IC-21425, October 18, 1995).
 
   
   Each Fund will operate at a zero expense ratio. To accomplish this, the
   payment of each Fund's operational expenses is subject to a Special Servicing
   Agreement described below as well as certain undertakings made by T. Rowe
   Price, under its Investment Management Agreement with Spectrum Growth and
   Spectrum Income Funds and Rowe Price-Fleming International, Inc. under its
   Investment Management Agreement with Spectrum International Fund. Fund
   expenses include: shareholder servicing fees and expenses; custodian and
   accounting fees and expenses; legal and auditing fees; expenses of preparing
   and printing prospectuses and shareholder reports; registration fees and
   expenses; proxy and annual meeting expenses, if any; and directors' fees and
   expenses.    
 
   Special Servicing Agreements One Special Servicing Agreement ("Agreement") is
   between and among the Spectrum Fund on behalf of Spectrum Income and Spectrum
   Growth Funds, the underlying funds, and T. Rowe Price. A second Special
   Servicing Agreement is between and among Spectrum Fund, on behalf of Spectrum
   International Fund, the underlying funds, Price-Fleming, and T. Rowe Price.
 
   Each Agreement provides that, if the Board of Directors of any Underlying
   Price Fund determines that such Underlying Fund's share of the aggregate
   expenses of Spectrum Fund is less than the estimated savings to the
   Underlying Price Fund from the operation of Spectrum Fund, the Underlying
   Price Fund will bear those expenses in proportion to the average daily value
   of its shares owned by Spectrum Fund, provided further that no Underlying
   Price Fund will bear such expenses in excess of the estimated savings to it.
   Such savings are expected to result primarily from the elimination of
   numerous separate shareholder accounts which are or would have been invested
   directly in the Underlying Price Funds and the resulting reduction in
   shareholder servicing costs. Although such cost savings are not certain, the
   estimated savings to the Underlying Price Funds generated by the operation of
   Spectrum Fund are expected to be sufficient to offset most, if not all, of
   the expenses incurred by Spectrum Fund.
 
   
   Each Special Servicing Agreement also gives authority to Spectrum Fund to
   utilize the Price name so long as (1) the Special Servicing Agreement is in
   effect, and (2) the assets of the Funds are invested pursuant to each Fund's
   objectives and policies in shares of the various Underlying Price Funds
   (except for such cash or cash items as the directors may determine to
   maintain from time to time to meet current expenses and    
<PAGE>
 
   
   redemptions). The Special Servicing Agreements provide that the Funds will
   utilize assets deposited with the custodian of each Fund from the sale of
   each Fund's shares to promptly purchase shares of the specified Underlying
   Price Funds, and will undertake redemption or exchange of such shares of the
   Underlying Price Funds in the manner provided by the objectives and policies
   of each Fund.
 
   Under the Investment Management Agreements with the Funds, and the Special
   Servicing Agreement, T. Rowe Price, with respect to Spectrum Income and
   Spectrum Growth, and Price-Fleming, with respect to Spectrum International,
   have agreed to bear any expenses of Spectrum Fund which exceed the estimated
   savings to each of the Underlying Price Funds. Of course, shareholders of
   Spectrum Fund will still indirectly bear their fair and proportionate share
   of the cost of operating the Underlying Price Funds in which the Spectrum
   Fund invests because, Spectrum Fund, as a shareholder of the Underlying Price
   Funds, will bear its proportionate share of any fees and expenses paid by the
   Underlying Price Funds. Spectrum Fund, as a shareholder of the selected
   Underlying Price Funds, will benefit only from cost-sharing reductions in
   proportion to its interest in such Underlying Price Funds.    
 
   Services
   Under the Management Agreement with each Fund, T. Rowe Price or Price-Fleming
   as the case may be, provides the Fund with discretionary investment services.
   Specifically, T. Rowe Price and Price-Fleming are responsible for supervising
   and directing the investments of the Fund in accordance with the Fund's
   investment objectives, program, and restrictions as provided in its
   prospectus and this Statement of Additional Information. T. Rowe Price and
   Price-Fleming are also responsible for effecting all security transactions on
   behalf of the Fund, including the negotiation of commissions and the
   allocation of principal business and portfolio brokerage. However, it should
   be understood that the Fund will invest its assets almost exclusively in the
   shares of the Underlying Price Funds and such investments will be made
   without the payment of any commission or other sales charges. In addition to
   these services, T. Rowe Price and Price-Fleming provides the Fund with
   certain corporate administrative services, including: maintaining the Fund's
   corporate existence and corporate records; registering and qualifying Fund
   shares under federal laws; monitoring the financial, accounting, and
   administrative functions of the Fund; maintaining liaison with the agents
   employed by the Fund such as the Fund's custodian and transfer agent;
   assisting the Fund in the coordination of such agents' activities; and
   permitting T. Rowe Price's and Price-Fleming's employees to serve as
   officers, directors, and committee members of the Fund without cost to the
   Fund.
 
   T. Rowe Price and Price-Fleming have agreed not to be paid a management fee
   for performing their services. However, T. Rowe Price and Price-Fleming will
   receive management fees from managing the Underlying Price Funds in which
   Spectrum Fund invests.
 
   Each Fund's Management Agreement also provides that T. Rowe Price or
   Price-Fleming, its directors, officers, employees, and certain other persons
   performing specific functions for the Fund will only be liable to the Fund
   for losses resulting from willful misfeasance, bad faith, gross negligence,
   or reckless disregard of duty.
 
   Management Fees of Underlying Price Funds
   The Underlying Price Fund pays T. Rowe Price or Price-Fleming a fee ("Fee")
   which consists of two components: a Group Management Fee ("Group Fee") and an
   Individual Fund Fee ("Fund Fee"). The Fee is paid monthly to T. Rowe Price or
   Price-Fleming on the first business day of the next succeeding calendar month
   and is calculated as described below.
 
   The monthly Group Fee ("Monthly Group Fee") is the sum of the daily Group Fee
   accruals ("Daily Group Fee Accruals") for each month. The Daily Group Fee
   Accrual for any particular day is computed by multiplying the Price Funds'
   group fee accrual as determined below ("Daily Price Funds' Group Fee
   Accrual") by the ratio of the Price Fund's net assets for that day to the sum
   of the aggregate net assets of the Price Funds for that day. The Daily Price
   Funds' Group Fee Accrual for any particular day is calculated by
<PAGE>
 
   multiplying the fraction of one (1) over the number of calendar days in the
   year by the annualized Daily Price Funds' Group Fee Accrual for that day as
   determined in accordance with the following schedule:

   For the purpose of calculating the Group Fee, the Price Funds include all the
   mutual funds distributed by T. Rowe Price Investment Services, Inc.,
   (excluding the T. Rowe Price Spectrum Funds, and any institutional, index, or
   private label mutual funds). For the purpose of calculating the Daily Price
   Funds' Group Fee Accrual for any particular day, the net assets of each Price
   Fund are determined in accordance with the Funds' prospectus as of the close
   of business on the previous business day on which the Fund was open for
   business.
 
   The monthly Fund Fee ("Monthly Fund Fee") is the sum of the daily Fund Fee
   accruals ("Daily Fund Fee Accruals") for each month. The Daily Fund Fee
   Accrual for any particular day is computed by multiplying the fraction of one
   (1) over the number of calendar days in the year by the individual Fund Fee
   Rate and multiplying this product by the net assets of the Fund for that day,
   as determined in accordance with the Fund's prospectus as of the close of
   business on the previous business day on which the Fund was open for
   business. The individual fund fees and total management fees of the
   Underlying Price Funds are listed in the chart below:

 CUSTODIAN
 -------------------------------------------------------------------------------
   The Underlying Funds of the Spectrum International Fund have entered into a
   Custodian Agreement with The Chase Manhattan Bank, N.A., London, pursuant to
   which portfolio securities which are purchased outside the United States are
   maintained in the custody of various foreign branches of The Chase Manhattan
   Bank and such other custodians, including foreign banks and foreign
   securities depositories as are approved in accordance with regulations under
   the Investment Company Act of 1940. State Street Bank's main office is at 225
   Franklin Street, Boston, Massachusetts 02110. The address for The Chase
   Manhattan Bank, N.A., London is Woolgate House, Coleman Street, London, EC2P
   2HD, England.
 
   State Street Bank and Trust Company, under an agreement with Spectrum Fund,
   on behalf of the Income, Growth, and International Funds, is the custodian
   for the Fund's U.S. securities and cash, but it does not participate in the
   Funds' investment decisions. The Bank maintains shares of the Spectrum Funds
   in the book entry system of such Funds' transfer agent, T. Rowe Price
   Services. The domestic Underlying Funds' portfolio securities purchased in
   the U.S. are maintained in the custody of the Bank and may be entered into
   the Federal Reserve Book Entry System, or the security depository system of
   the Depository Trust Corporation.
 
 
 
 SHAREHOLDER SERVICES
 -------------------------------------------------------------------------------
   The Fund from time to time may enter into agreements with outside parties
   through which shareholders hold Fund shares. The shares would be held by such
   parties in omnibus accounts. The agreements would provide for payments by the
   Fund to the outside party for shareholder services provided to shareholders
   in the omnibus accounts.
 
 
 
 CODE OF ETHICS
 -------------------------------------------------------------------------------
   The Fund's investment adviser (T. Rowe Price) has a written Code of Ethics
   which requires all employees to obtain prior clearance before engaging in
   personal securities transactions. In addition, all employees must report
   their personal securities transactions within 10 days. Employees will not be
   permitted to effect transactions in a security: if there are pending client
   orders in the security; the security has been purchased or sold by a client
   within seven calendar days; the security is being considered for purchase for
   a client; a change has occurred in T. Rowe Price's rating of the security
   within seven calendar days prior to the date of the proposed transaction; or
   the security is subject to internal trading restrictions. In addition,
   employees are prohibited from profiting from short-term trading (e.g.,
   purchases and sales involving the same security within 60 days). Any material
   violation of the Code of Ethics is reported to the Board of the Fund. The
   Board also reviews the administration of the Code of Ethics on an annual
   basis.
 
 
 
 PRICING OF SECURITIES
 -------------------------------------------------------------------------------
   
   The securities of the Underlying Price Funds held by each Fund are valued at
   the closing net asset value per share of each Underlying Price Fund on the
   day of valuation. Assets for which the valuation procedures are inappropriate
   or are deemed not to reflect fair value are stated at fair value as
   determined in good faith by or under the supervision of the officers of the
   Fund, as authorized by the Board of Directors. For the Growth Fund,
   short-term money market investments are valued at amortized cost in local
   currency which, when combined with accrued interest, approximates market
   value. For the International Fund, short-term debt securities are valued at
   amortized cost, which approximates fair market value. For the Income Fund,
   securities with less than one year to maturity are stated at fair value which
   is determined by using a matrix system that establishes a value for each
   security based on money market yields. Also, for the International    
<PAGE>
 
   
   Fund, portfolio securities of the Underlying Funds may be listed on foreign
   exchanges that can open on days when the Underlying Funds do not compute
   their prices. As a result, the Underlying Funds', and consequently the
   Spectrum International Fund's net asset value may be significantly affected
   by trading on days when shareholders cannot make transactions.    
 
 
 
 NET ASSET VALUE PER SHARE
 -------------------------------------------------------------------------------
   The purchase and redemption price of the Fund's shares is equal to the Fund's
   net asset value per share or share price. The Fund determines its net asset
   value per share by subtracting its liabilities (including accrued expenses
   and dividends payable) from its total assets (the market value of the
   securities the Fund holds plus cash and other assets, including income
   accrued but not yet received) and dividing the result by the total number of
   shares outstanding. The net asset value per share of the Fund is normally
   calculated as of the close of trading on the New York Stock Exchange ("NYSE")
   every day the NYSE is open for trading. The NYSE is closed on the following
   days: New Year's Day, Dr. Martin Luther King, Jr. Holiday, Presidents' Day,
   Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day, and
   Christmas Day.
 
   Determination of net asset value (and the offering, sale redemption and
   repurchase of shares) for the Fund may be suspended at times (a) during which
   the NYSE is closed, other than customary weekend and holiday closings, (b)
   during which trading on the NYSE is restricted, (c) during which an emergency
   exists as a result of which disposal by the Fund of securities owned by it is
   not reasonably practicable or it is not reasonably practicable for the Fund
   fairly to determine the value of its net assets, or (d) during which a
   governmental body having jurisdiction over the Fund may by order permit such
   a suspension for the protection of the Fund's shareholders; provided that
   applicable rules and regulations of the Securities and Exchange Commission
   (or any succeeding governmental authority) shall govern as to whether the
   conditions prescribed in (b), (c), or (d) exist.
 
 
 
 DIVIDENDS AND DISTRIBUTIONS
 -------------------------------------------------------------------------------
   Unless you elect otherwise, capital gain distributions, if any, will be
   reinvested on the reinvestment date using the NAV per share of that date. The
   reinvestment date normally precedes the payment date by about 10 days,
   although the exact timing is subject to change.
 
 
 
 TAX STATUS
 -------------------------------------------------------------------------------
   The Fund intends to qualify as a "regulated investment company" under
   Subchapter M of the Internal Revenue Code of 1986, as amended ("Code").
 
   A portion of the dividends paid by the Growth and Income Funds may be
   eligible for the dividends-received deduction for corporate shareholders. The
   dividends of the Spectrum International Fund will not be eligible for this
   deduction, if, as expected, none of the fund's income consists of dividends
   paid by U.S. corporations. Capital gain distributions paid from these Funds
   are never eligible for the dividends-received deduction. For tax purposes, it
   does not make any difference whether dividends and capital gain distributions
   are paid in cash or in additional shares. The Fund must declare dividends by
   December 31 of each year equal to at least 98% of ordinary income (as of
   December 31) and capital gains (as of October 31) in order to avoid a federal
   excise tax and distribute within 12 months 100% of ordinary income and
   capital gains as of December 31 to avoid a federal income tax.
 
   At the time of your purchase, the Fund's net asset value may reflect
   undistributed income (Growth and International Funds), capital gains or net
   unrealized appreciation of securities held by the Fund. A
<PAGE>
 
   subsequent distribution to you of such amounts, although constituting a
   return of your investment, would be taxable. For federal income tax purposes,
   the Fund is permitted to carry forward its net realized capital losses, if
   any, for eight years and realize net capital gains up to the amount of such
   losses without being required to pay taxes on, or distribute, such gains.
 
   If, in any taxable year, the Fund should not qualify as a regulated
   investment company under the code: (i) the Fund would be taxed at normal
   corporate rates on the entire amount of its taxable income, if any, without
   deduction for dividends or other distributions to shareholders; and (ii) the
   Fund's distributions to the extent made out of the Fund's current or
   accumulated earnings and profits would be taxable to shareholders as ordinary
   dividends (regardless of whether they would otherwise have been considered
   capital gain dividends), and, for Spectrum Income and Spectrum Growth Funds,
   would qualify for the 70% deduction for dividends received by corporations.
   However, for Spectrum International Fund, the dividends will not be eligible
   for the 70% deduction for dividends received by corporations, if, as
   expected, none of the Fund's income consists of dividends paid by U.S.
   corporations.
 
 
                        Taxation of Foreign Shareholders
 
   The Code provides that dividends from net income will be subject to U.S. tax.
   For shareholders who are not engaged in a business in the U.S., this tax
   would be imposed at the rate of 30% upon the gross amount of the dividends in
   the absence of a Tax Treaty providing for a reduced rate or exemption from
   U.S. taxation. Distributions of net long-term capital gains realized by the
   Fund are not subject to tax unless the foreign shareholder is a nonresident
   alien individual who was physically present in the U.S. during the tax year
   for more than 182 days.
 
 
 
 YIELD INFORMATION
 -------------------------------------------------------------------------------
 
                              Spectrum Income Fund
 
   An income factor is calculated for each security in the portfolio based upon
   the security's market value at the beginning of the period and yield as
   determined in conformity with regulations of the Securities and Exchange
   Commission. The income factors are then totaled for all securities in the
   portfolio. Next, expenses of the Fund for the period, net of expected
   reimbursements, are deducted from the income to arrive at net income, which
   is then converted to a per share amount by dividing net income by the average
   number of shares outstanding during the period. The net income per share is
   divided by the net asset value on the last day of the period to produce a
   monthly yield which is then annualized. If applicable, a taxable-equivalent
   yield is calculated by dividing this yield by one minus the effective federal
   income tax rate. Quoted yield factors are for comparison purposes only, and
   are not intended to indicate future performance or forecast the dividend per
   share of the Fund.
 
   The yield of the Fund calculated under the above-described method for the
   month ended December 31, 1997, was 6.05%.
 
 
 
 INVESTMENT PERFORMANCE
 -------------------------------------------------------------------------------
 
                            Total Return Performance
 
   The Fund's calculation of total return performance includes the reinvestment
   of all capital gain distributions and income dividends for the period or
   periods indicated, without regard to tax consequences to a shareholder in the
   Fund. Total return is calculated as the percentage change between the
   beginning value of a static account in the Fund and the ending value of that
   account measured by the then current net asset value, including all shares
   acquired through reinvestment of income and capital gain dividends. The
   results shown are historical and should not be considered indicative of the
   future performance of the Fund. Each average
<PAGE>
 
   annual compound rate of return is derived from the cumulative performance of
   the Fund over the time period specified. The annual compound rate of return
   for the Fund over any other period of time will vary from the average.

   From time to time, in newsletters and other publications issued by T. Rowe
   Price Investment Services, Inc., T. Rowe Price mutual fund portfolio managers

                           Other Features and Benefits
 
   The Fund is a member of the T. Rowe Price family of Funds and may help
   investors achieve various long-term investment goals, which include, but are
   not limited to, investing money for retirement, saving for a down payment on
   a home, or paying college costs. To explain how the Fund could be used to
   assist investors in planning for these goals and to illustrate basic
   principles of investing, various worksheets and guides prepared by T. Rowe
   Price Associates, Inc. and/or T. Rowe Price Investment Services, Inc. may be
   made available.
 
 
                       No-Load Versus Load and 12b-1 Funds
 
   Unlike the T. Rowe Price funds, many mutual funds charge sales fees to
   investors or use fund assets to finance distribution activities. These fees
   are in addition to the normal advisory fees and expenses charged by all
   mutual funds. There are several types of fees charged which vary in magnitude
   and which may often be used in combination. A sales charge (or "load") can be
   charged at the time the fund is purchased (front-end load) or at the time of
   redemption (back-end load). Front-end loads are charged on the total amount
   invested. Back-end loads or "redemption fees" are charged either on the
   amount originally invested or on the amount redeemed. 12b-1 plans allow for
   the payment of marketing and sales expenses from fund assets. These expenses
   are usually computed daily as a fixed percentage of assets.
 
   The Fund is a no-load fund which imposes no sales charges or 12b-1 fees.
   No-load funds are generally sold directly to the public without the use of
   commissioned sales representatives. This means that 100% of your purchase is
   invested for you.
 
 
                               Redemptions in Kind
 
   In the unlikely event a shareholder were to receive an in kind redemption of
   portfolio securities of the Fund, brokerage fees could be incurred by the
   shareholder in a subsequent sale of such securities.
 
 
                     Issuance of Fund Shares for Securities
 
   Transactions involving issuance of Fund shares for securities or assets other
   than cash will be limited to (1) bona fide reorganizations; (2) statutory
   mergers; or (3) other acquisitions of portfolio securities that: (a) meet the
   investment objective and policies of the Fund; (b) are acquired for
   investment and not for resale except in accordance with applicable law; (c)
   have a value that is readily ascertainable via listing on or trading in a
   recognized United States or international exchange or market; and (d) are not
   illiquid.
 
 
 
 CAPITAL STOCK
 -------------------------------------------------------------------------------
   The Articles of Incorporation of Spectrum Fund currently establish three
   series (i.e., the Income Fund, the Growth Fund, and the International Fund),
   each of which represents a separate class of the Corporation's shares and has
   different objectives and investment policies. The Articles of Incorporation
   also provide that the Board of Directors may issue additional series of
   shares. Each share of each Fund represents an equal proportionate share in
   that Fund, with each other share, and is entitled to such dividends and
   distributions of income belonging to that Fund as are declared by the
   Directors. In the event of the liquidation of a Fund, each share is entitled
   to a pro rata share of the net assets of that Fund.
 
   The Fund's Charter authorizes the Board of Directors to classify and
   reclassify any and all shares which are then unissued, including unissued
   shares of capital stock into any number of classes or series, each class or
   series consisting of such number of shares and having such designations, such
   powers, preferences, rights, qualifications, limitations, and restrictions,
   as shall be determined by the Board subject to the Investment Company Act and
   other applicable law. The shares of any such additional classes or series
   might therefore differ from the shares of the present class and series of
   capital stock and from each other as to preferences, conversions or other
   rights, voting powers, restrictions, limitations as to dividends,
   qualifications or terms or conditions of redemption, subject to applicable
   law, and might thus be superior or inferior to the capital stock or to other
   classes or series in various characteristics. The Board of Directors may
   increase or decrease the
<PAGE>
 
   aggregate number of shares of stock or the number of shares of stock of any
   class or series that the Fund has authorized to issue without shareholder
   approval.
 
   Except to the extent that the Fund's Board of Directors might provide by
   resolution that holders of shares of a particular class are entitled to vote
   as a class on specified matters presented for a vote of the holders of all
   shares entitled to vote on such matters, there would be no right of class
   vote unless and to the extent that such a right might be construed to exist
   under Maryland law. The Charter contains no provision entitling the holders
   of the present class of capital stock to a vote as a class on any matter.
   Accordingly, the preferences, rights, and other characteristics attaching to
   any class of shares, including the present class of capital stock, might be
   altered or eliminated, or the class might be combined with another class or
   classes, by action approved by the vote of the holders of a majority of all
   the shares of all classes entitled to be voted on the proposal, without any
   additional right to vote as a class by the holders of the capital stock or of
   another affected class or classes.
 
   Shareholders are entitled to one vote for each full share held (and
   fractional votes for fractional shares held) and will vote in the election of
   or removal of directors (to the extent hereinafter provided) and on other
   matters submitted to the vote of shareholders. There will normally be no
   meetings of shareholders for the purpose of electing directors unless and
   until such time as less than a majority of the directors holding office have
   been elected by shareholders, at which time the directors then in office will
   call a shareholders' meeting for the election of directors. Except as set
   forth above, the directors shall continue to hold office and may appoint
   successor directors. Voting rights are not cumulative, so that the holders of
   more than 50% of the shares voting in the election of directors can, if they
   choose to do so, elect all the directors of the Fund, in which event the
   holders of the remaining shares will be unable to elect any person as a
   director. As set forth in the By-Laws of the Fund, a special meeting of
   shareholders of the Fund shall be called by the Secretary of the Fund on the
   written request of shareholders entitled to cast at least 10% of all the
   votes of the Fund entitled to be cast at such meeting. Shareholders
   requesting such a meeting must pay to the Fund the reasonably estimated costs
   of preparing and mailing the notice of the meeting. The Fund, however, will
   otherwise assist the shareholders seeking to hold the special meeting in
   communicating to the other shareholders of the Fund to the extent required by
   Section 16(c) of the Investment Company Act of 1940.
