 ABOUT THE FUNDS
                                        1
 FUND, MARKET, AND RISK CHARACTERISTICS: WHAT TO EXPECT
 ----------------------------------------------------------
   To help you decide whether these funds are appropriate for you, this section
   reviews their investment objectives, strategies, and potential risks.
 
 
 What is each fund's objective?
 
   Cash Reserves Fund  The fund seeks preservation of capital and liquidity and,
   consistent with these, the highest possible current income.
 
   Limited-Term Bond Fund  The fund seeks a high level of income consistent with
   moderate fluctuations in principal value.
 
   GNMA Fund  The fund seeks a high level of income and maximum credit
   protection by investing at least 65% of total assets in GNMA securities
   backed by the full faith and credit of the U.S. government.
 
 
 What is each fund's principal investment strategy?
 
   
   Cash Reserves Fund  The fund, which is managed to provide a stable share
   price of $1.00, invests in high-quality, U.S. dollar-denominated money market
   securities of U.S. and foreign issuers. The fund's average weighted maturity
   will not exceed 90 days, and its yield will fluctuate with changes in
   short-term interest rates. In selecting securities, fund managers may examine
   the relationships among yields on various types and maturities of money
   market securities in the context of their outlook for interest rates. For
   example, commercial paper often offers a yield advantage over Treasury bills.
   And if rates are expected to fall, longer maturities, which typically have
   higher yields than shorter maturities, may be purchased to try to preserve
   the fund's income level. Conversely, shorter maturities may be favored if
   rates are expected to rise.    
 
   Limited-Term Bond Fund  The fund invests at least 65% of total assets in
   short- and intermediate-term bonds. There are no maturity limitations on
   individual securities purchased, but the fund's dollar-weighted average
   effective maturity (discussed later in this section) will not exceed five
   years. Targeting effective maturity provides additional flexibility in
   portfolio management but, all else being equal, could result in higher
   volatility than would be true of a fund targeting a stated maturity or
   maturity range.
 
   
   At least 90% of the fund's portfolio will consist of investment-grade
   securities rated in the four highest credit categories (AAA, AA, A, BBB) by
   at least one national rating agency or the equivalent from T. Rowe Price when
   other ratings are not available. In an effort to enhance yield, up to 10% of
   assets can be invested in below-investment-grade securities, commonly
   referred to as "junk" bonds, including those with the lowest rating. These
   holdings may include    
<PAGE>
 
   
T. ROWE PRICE                                     
   mortgage-backed securities, derivatives, and foreign investments. The fund's
   income level should be higher than the money fund's, but its share price will
   vary.
 
   Within this broad structure, investment decisions reflect the manager's
   outlook for interest rates and the economy as well as the prices and yields
   of the various securities. For example, if rates are expected to fall, the
   manager may seek longer-term securities (within the fund's program) that
   would provide higher yields and appreciation potential. And if, for instance,
   the economic outlook is positive, the manager may take advantage of the 10%
   "basket" for noninvestment-grade bonds.
 
   GNMA Fund  We will invest at least 65% of total assets in mortgage-backed
   securities issued by the Government National Mortgage Association (GNMA), an
   agency of the Department of Housing and Urban Development. These securities
   represent "pools" of mortgage loans that are either guaranteed by the Federal
   Housing Administration or the Veterans Administration. Mortgage lenders pool
   individual home mortgages to back a certificate or bond, which is then sold
   to investors. Interest and principal payments from the underlying mortgages
   are passed through to investors.
 
   GNMA guarantees the timely payment of interest and principal on its
   securities, a guarantee backed by the U.S. Treasury. GNMAs generally offer
   higher yields than Treasuries of similar maturity, for reasons explained in
   the next section. 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.
 
   
   Up to 35% of assets can be invested in other types of high-quality securities
   (AAA or AA), which are not guaranteed by the U.S. government, such as
   privately issued mortgage securities and corporate bonds. The fund may also
   purchase derivatives. The fund's effective maturity generally will vary
   between three and 12 years and will be influenced by principal prepayments of
   GNMA and other mortgage-backed securities.    
 
   In selecting securities, fund managers may weigh the characteristics of
   various types of mortgage securities and examine yield relationships in the
   context of their outlook for interest rates and the economy. For example, if
   rates are expected to fall, mortgage securities expected to have
   below-average prepayment rates may be purchased and assets may also be
   allocated to Treasury notes or bonds, which may appreciate in that
   environment.

RUNNING H/F 1
   
   The funds may sell holdings for a variety of reasons, such as to adjust a
   portfolio's average maturity or quality, or to shift assets into
   higher-yielding securities.    
 
  . For details about each fund's investment program, please see the Investment
   Policies and Practices section.
 
 
 What are the main risks of investing in the funds?
 
   Cash Reserves Fund
   
   Since money market funds are managed to maintain a constant $1.00 share
   price, they should have little risk of principal loss. However, there is no
   assurance the fund will avoid principal losses if fund holdings default or
   interest rates rise sharply in an unusually short period. In addition, the
   fund's yield will vary; it is not fixed for a specific period like the yield
   on a bank certificate of deposit. This should be an advantage when interest
   rates are rising but not when rates are falling. An investment in the fund is
   not insured or guaranteed by the Federal Deposit Insurance Corporation (FDIC)
   or any other government agency. Although the fund seeks to preserve the value
   of your investment at $1.00 per share, it is possible to lose money by
   investing in the fund.    
 
   GNMA and Limited-Term Bond Funds
  . Interest rate risk  This is the decline in bond prices that accompanies a
   rise in the overall level of interest rates, as shown in Table 4 in this
   section. This is the major source of risk for investors in these funds.
   However, because short-term bond funds are less sensitive to interest rate
   increases or decreases than longer-term bond funds, price volatility for the
   Limited-Term Bond Fund is expected to be relatively modest. Interest rate
   risk also will be greater for the GNMA Fund to the extent it invests in the
   forward market.
 
   
  . Credit risk  This is the chance that any of the funds' holdings will have
   its credit rating downgraded or will default (fail to make scheduled interest
   or principal payments), potentially reducing the fund's income level and
   share price. While the Limited-Term Bond Fund's overall credit quality is
   high, its medium-quality securities are more susceptible to adverse economic
   conditions. The fund's investments in junk bonds should, and some of its BBB
   securities may also, be regarded as speculative.The GNMA Fund's exposure to
   credit risk is significantly less since the fund invests primarily in GNMAs,
   which are backed by the full faith and credit of the U.S. government. The
   remaining 35% of assets are high quality but not necessarily government
   backed.
 
  . The funds may continue to hold a security that has been downgraded after
   purchase.    
 
  . Prepayment risk and extension risk  Because each fund can invest in
   mortgage-backed securities, it has special risks related to changing interest
   rates. These risks should generally be significantly more pronounced for the
   GNMA Fund. A mortgage-backed bond, unlike most other bonds, can be hurt when
   interest
<PAGE>
 
T. ROWE PRICE
   rates fall, because homeowners tend to refinance and prepay principal. The
   loss of high-yielding underlying mortgages and the reinvestment of proceeds
   at lower interest rates can reduce the bond's potential price gain in
   response to falling interest rates, can reduce the bond's yield, or even
   cause the bond's price to fall below what an investor paid for it, resulting
   in a capital loss. Any of these developments could cause a decrease in the
   fund's income, share price, or total return.
 
   
   Extension risk refers to a rise in interest rates that causes a fund's
   average maturity to lengthen unexpectedly due to a drop in mortgage
   prepayments. This would increase the fund's sensitivity to rising rates and
   its potential for price declines.
 
  . Derivatives risk  Shareholders are also exposed to the possibility that our
   investments in these complex and volatile instruments could affect each
   fund's share price. In addition to CMOs and better-known instruments such as
   futures and options, other derivatives used in limited fashion by the funds
   include interest-only (IO) and principal-only (PO) securities known as
   "strips." The value of these instruments is derived from underlying
   securities such as mortgage-backed bonds. All these instruments can be highly
   volatile, and their value can fall dramatically in response to rapid or
   unexpected changes in the mortgage or interest rate environment.    
 
   Cash Reserves and Limited-Term Bond Funds
   
  . Foreign investing risk  To the extent each fund holds foreign bonds, it will
   be subject to special risks whether the bonds are denominated in U.S. dollars
   or foreign currencies. These risks include potentially adverse political and
   economic developments overseas, greater volatility, less liquidity, and the
   possibility that foreign currencies will decline against the dollar, lowering
   the value of securities denominated in those currencies and possibly the
   fund's share price. Currency risk affects each fund to the extent that it
   holds nondollar foreign bonds.    
 
   As with any mutual fund, there can be no guarantee the funds will achieve
   their objectives.
 
   
  . The yield of each fund will fluctuate with changing market conditions and
   interest rate levels. The bond funds' share prices will fluctuate as interest
   rates change, so when you sell your shares, you may lose money.    
 
 
 How can I tell which fund is most appropriate for me?
 
   Consider your investment goals, your time horizon for achieving them, and
   your tolerance for risk. These funds may be appropriate for you if you seek
   higher yields for the fixed income portion of your portfolio and can meet the
   funds' $25,000 initial purchase requirement. Use the table entitled
   Differences Among Funds, which summarizes each fund's main characteristics,
   to help choose a fund (or funds) for your particular needs. For example, only
   the
<PAGE>
 
RUNNING H/F 1
   money fund is designed to provide principal stability, which makes it a good
   choice for you if the stability and accessibility of your investment are more
   important than the opportunity for higher income or total return. However, if
   you are investing for the highest possible income and can tolerate some price
   fluctuation, you should consider a longer-term bond fund. The funds may be
   used for both regular and tax-deferred accounts, such as IRAs.
 
  . The bond funds should not represent your complete investment program or be
   used for short-term trading purposes.
 
 
 How has each fund performed in the past?
 
   
   The bar charts and the average annual total return table indicate risk by
   illustrating how much returns can differ from one year to the next. Each
   fund's past performance is no guarantee of its future returns.    
 
   The funds can also experience short-term performance swings, as shown in the
   following charts by the best and worst calendar quarter returns during the
   years depicted in the charts.

 OTHER INFORMATION ABOUT THE FUNDS
 ----------------------------------------------------------
 
 What are the funds' potential rewards?
 
  . Cash Reserves Fund  offers a relatively secure, liquid investment for money
   you may need for occasional or unexpected expenses and for money awaiting
   investment in longer-term bond or stock funds. In addition to preserving
   capital, the fund seeks to provide the highest possible income available from
   low-risk, short-term securities.
 
  . Limited-Term Bond Fund's income level should generally be above that of a
   money market fund, but less than that of a long-term bond fund. Its share
   price should fluctuate less than a longer-term bond fund. The manager seeks
   to adjust the fund's weighted average maturity to increase total returns when
   interest rates fall and to minimize the effects of rising rates.
 
  . GNMA Fund's emphasis on mortgage-backed bonds is designed to offer higher
   income than is available from U.S. Treasury securities without any decrease
   in credit quality. In addition, when interest rates rise, GNMAs may have
   better overall returns than Treasury and corporate issues, although they may
   not do as well when rates decline.
 
 
 How do the Summit Funds achieve their low-cost advantage?
 
   The advantage reflects their more favorable ratio of expenses to assets. The
   $25,000 initial purchase requirement means that the average account balance
   in each Summit Fund is high. Since shareholder recordkeeping costs - a
   substantial portion of fund expenses - are basically the same for all sizes
   of accounts, a fund with larger account balances can spread the expenses over
   more investment dollars, achieving a low overall expense ratio. Expenses are
   deducted from fund assets before dividends are paid, as explained previously,
   so lower costs result in higher dividends for Summit Fund shareholders.
<PAGE>
 
T. ROWE PRICE
 How does the portfolio manager try to reduce risk?
 
   Consistent with each fund's objective, the portfolio manager uses various
   tools to try to reduce risk and increase total return, including:
 
  . Diversification of assets to reduce the impact of a single holding on a
   fund's net asset value.
 
  . Thorough credit research by our own analysts.
 
  . Adjustment of fund duration to try to reduce the drop in price when interest
   rates rise or to benefit from the rise in price when rates fall. Duration is
   a measure of a fund's sensitivity to interest rate changes.
 
 
 Is there other information I can review before making a decision?
 
   
   Investment Policies and Practices in Section 3 discusses various types of
   portfolio securities the funds may purchase as well as types of management
   practices the funds may use.    
 
 
 SOME BASICS OF FIXED INCOME INVESTING
 ----------------------------------------------------------
 
 Is a fund's yield fixed or will it vary?
 
   It will vary. The yield is calculated every day by dividing a fund's net
   income per share, expressed at annual rates, by the share price. Since both
   income and share price will fluctuate, a fund's yield will also vary.
   (Although money fund prices are stable, income is variable.)
 
 
 Is yield the same as total return?
 
   Not for bond funds. The total return reported for a fund is the result of
   reinvested distributions (income and capital gains) and the change in share
   price for a given time period. Income is always a positive contributor to
   total return and can enhance a rise in share price or serve as an offset to a
   drop in share price. Since money funds are managed to maintain a stable share
   price, their yield and total return should be the same.
 
 
 What is credit quality and how does it affect yield?
 
   Credit quality refers to a bond issuer's expected ability to make all
   required interest and principal payments on time. Because highly rated
   issuers represent less risk, they can borrow at lower interest rates than
   less creditworthy issuers. Therefore, a fund investing in high-quality
   securities should have a lower yield than an otherwise comparable fund
   investing in lower-quality securities.
<PAGE>
 
RUNNING H/F 1
 What is meant by a bond fund's maturity?
 
   
   Every bond has a stated maturity date when the issuer must repay the bond's
   entire principal value to the investor. However, many bonds are "callable,"
   meaning their principal can be repaid earlier, on or after specified call
   dates. Bonds are most likely to be called when interest rates are falling
   because the issuer can refinance at a lower rate, just as a homeowner
   refinances a mortgage. In that environment, a bond's "effective maturity" is
   usually its nearest call date. For example, the rate at which homeowners pay
   down their mortgage principal determines the effective maturity of
   mortgage-backed bonds.    
 
   A bond mutual fund has no real maturity, but it does have a weighted average
   maturity and an average effective maturity. This number is an average of the
   stated or effective maturities of the underlying bonds, with each bond's
   maturity "weighted" by the percentage of fund assets it represents. Funds
   that target effective maturities normally use the effective, rather than
   stated, maturities of the bonds in the portfolio when computing the average.
   This provides additional flexibility in portfolio management but, all else
   being equal, could result in higher volatility than a fund targeting a stated
   maturity or maturity range.
 
 
 What is meant by a bond fund's duration?
 
   Duration is a calculation that seeks to measure the price sensitivity of a
   bond or a bond fund to changes in interest rates. It measures this
   sensitivity more accurately than maturity because it takes into account the
   time value of cash flows generated over the bond's life. Future interest and
   principal payments are discounted to reflect their present value and then are
   multiplied by the number of years they will be received to produce a value
   expressed in years - the duration. Effective duration takes into account call
   features and sinking fund payments that may shorten a bond's life.
 
   Since duration can also be computed for bond funds, you can estimate the
   effect of interest rates on share price by multiplying fund duration by an
   expected change in interest rates. For example, the price of a bond fund with
   a duration of five years would be expected to fall approximately 5% if rates
   rose by one percentage point. (T. Rowe Price bond fund shareholder reports
   show duration.)
 
 
 How is a bond's price affected by changes in interest rates?
 
   When interest rates rise, a bond's price usually falls, and vice versa. In
   general, the longer a bond's maturity, the greater the price increase or
   decrease in response to a given change in rates, as shown in Table 4.

T. ROWE PRICE
   
 The table reflects yields on Treasury securities as of December 31, 1998. The
 table may not be as representative of price changes for other types of bonds,
 including mortgage-backed securities, because of prepayments. This is an
 illustration and does not represent expected yields or share price changes of
 any T. Rowe Price fund.    
 
   Since the average effective maturity of bonds held by the Limited-Term Bond
   Fund is expected to be no more than five years, the fund's share price, like
   the value of the underlying bonds in its portfolio, should fluctuate less
   than a fund that holds bonds with longer average effective maturities. If
   mortgage prepayments should accelerate in a falling interest rate
   environment, GNMA securities may appreciate less than shown in the example
   above. The amount of appreciation would depend on the characteristics of the
   mortgages, such as their coupon or maturity.
 
 
 Do money market securities react to changes in interest rates?
 
   Yes. As interest rates change, the prices of money market securities
   fluctuate, but changes are usually small because of their very short
   maturities. Investments are typically held until maturity in a money fund to
   help the fund maintain a $1.00 share price.

 PRICING SHARES AND RECEIVING SALE PROCEEDS
 ----------------------------------------------------------
   Here are some procedures you should know when investing in a T. Rowe Price
   fund.
 
 
 How and when shares are priced
 
   Bond and money funds
   The share price (also called "net asset value" or NAV per share) for the
   funds 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. Current market values are used to price
   fund shares. Amortized cost is used to value money fund securities.
 
   
  . 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 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
 
  . When filling out the New Account Form, you may wish to give yourself the
   widest range of options for receiving proceeds from a sale.
 
   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
<PAGE>
 
T. ROWE PRICE
   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 each 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 are exchanging into
   another fund, your purchase order will be priced at that fund's NAV on the
   fifth business day after the exchange. If you are exchanging into a bond or
   money fund, your new investment will not begin to earn dividends until the
   sixth business day.    
 
  . If for some reason we cannot accept your request to sell shares, we will
   contact you.
 
 
 
 USEFUL INFORMATION ON DISTRIBUTIONS AND TAXES
 ----------------------------------------------------------
  . 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.
 
   Income dividends
  . Bond funds declare 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.
 
  . Dividends are paid 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
<PAGE>
 
RUNNING H/F 1
   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.
 
  . Money funds declare income dividends daily to shareholders of record as of
   12 noon ET on that day. Wire purchase orders received before 12 noon ET
   receive the dividend for that day. Other purchase orders receive the dividend
   on the next business day after payment has been received.
 
   Capital gains
  . Since money funds are managed to maintain a constant share price, they are
   not expected to make capital gain distributions.
 
  . 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
 
  . 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.
 
   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.
<PAGE>
 
T. ROWE PRICE
   Taxes on fund distributions
  . The following summary does not apply to retirement accounts, such as IRAs,
   which are not subject to current tax.
 
   
   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 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, and long-term gains on securities held more
   than 12 months are taxed at a maximum rate of 20%. If you realized a loss on
   the sale or exchange of fund shares that you held six months or less, your
   short-term loss will be reclassified to a long-term loss to the extent of any
   long-term capital gain distribution received during the period you held the
   shares.    
 
  . Distributions are taxable whether reinvested in additional shares or
   received in cash.
 
   Tax effect of buying shares before a capital gain 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 taxable distributions.
 
 
 
 TRANSACTION PROCEDURES AND SPECIAL REQUIREMENTS
 ----------------------------------------------------------
  . 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 each fund or transfer agent, and the fund
   can redeem shares you own in this or another identically registered T. Rowe
   Price fund as reimbursement. Each fund and its agents have the right to
   reject or cancel any purchase, exchange, or redemption due to nonpayment.
<PAGE>
 
RUNNING H/F 1
   U.S. dollars
   All purchases must be paid for in U.S. dollars; checks must be drawn on U.S.
   banks.
 
 
 Sale (Redemption) Conditions
 
   Holds on immediate redemptions: 10-day hold
   If you sell shares that you just purchased and paid for by check or ACH
   transfer, the funds 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. If, during the
   clearing period, we receive a check drawn against your bond or money market
   account, it will be returned marked "uncollected." (The 10-day hold does not
   apply to the following: purchases 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 boxes that state 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 or computer are
   genuine; they 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. 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
 
  . 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.

   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 nonmoney fund are
   not exempt); and 2) systematic purchases or redemptions (see Information
   About Your 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.
 
  . 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 $10,000. If your balance
   is below $10,000 for three months or longer, we have the right to close your
   account after giving you 60 days in which to increase your balance.
 
 
 Signature Guarantees
 
  . 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:
<PAGE>
 
RUNNING H/F 1
  . 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 Summit Funds, Inc. (the "corporation") was incorporated in
   Maryland in 1993 and is a "diversified, open-end investment company," or
   mutual fund. Mutual funds pool money received from shareholders and invest it
   to try to achieve specified objectives.
 
   Currently, the corporation consists of three series: the Summit Cash Reserves
   Fund, the Summit Limited-Term Bond Fund, and the Summit GNMA Fund, each of
   which represents a separate class of shares and has different objectives and
   investment policies. Each of the Summit Funds was established in 1993.
 
  . Shareholders benefit from T. Rowe Price's 62 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 director 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
   instructions on voting by mail or telephone, or on the Internet.

 Who runs the funds?
 
   General Oversight
   
   The corporation is governed by a Board of Directors that meets regularly to
   review each fund's investments, performance, expenses, and other business
   affairs. The Board elects the corporation's officers. The policy of the
   corporation is that a majority of Board members are independent of T. Rowe
   Price Associates, Inc. (T. Rowe Price).    
 
  . All decisions regarding the purchase and sale of fund investments are made
   by T. Rowe Price  -  specifically by each fund's portfolio managers.
 
   Portfolio Management
   Each fund has an Investment Advisory Committee whose chairman has day-to-day
   responsibility for managing the fund and works with the committee in
   developing and executing the fund's investment program. The Investment
   Advisory Committees comprise the following members:
 
  . Cash Reserves Fund  Edward A. Wiese, Chairman, Patrice Berchtenbreiter Ely,
   Brian E. Burns, Robert P. Campbell, James M. McDonald, Joan R. Potee, Robert
   M. Rubino, and Gwendolyn G. Wagner. Mr. Wiese joined T. Rowe Price in 1984
   and has been managing investments since 1985.
 
  . Limited-Term Bond Fund  Edward A. Wiese, Chairman, Robert P. Campbell,
   Christy M. DiPietro, Charles B. Hill, Cheryl A.Mickel, Robert M. Rubino,
   Thomas E. Tewksbury, and Gwendolyn G. Wagner. Mr. Wiese joined T. Rowe Price
   in 1984 and has been managing investments since 1985.
 
  . GNMA Fund  Deborah L. Boyer, Chairman, Connice A. Bavely, Heather R. Landon,
   James M. McDonald, Edmund M. Notzon, and Gwendolyn G. Wagner. Ms. Boyer
   joined T. Rowe Price in 1996, and from 1993 - 1996 was an assistant vice
   president and government bond trader for First Chicago Capital Markets.
 
   The Management Fee
   
   Each fund pays T. Rowe Price an annual all-inclusive fee based on its average
   daily net assets. The funds calculate and accrue the fee daily. The fees for
   the funds for their most recent fiscal years were 0.45% for Cash Reserves,
   0.55% for Limited-Term Bond, and 0.60% for GNMA.    
 
 
 
 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.
<PAGE>
 
T. ROWE PRICE
 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 total
   return figures, which may be compared with various indices, other performance
   measures, or other mutual funds.
 
 
 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
 
   
   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 price at
   the end of the given period. 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.    
 
   For bond funds, the advertised or Securities and Exchange Commission (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.
 
   The money fund may advertise a current yield, reflecting the latest seven-day
   income annualized, or an "effective" yield, which assumes the income has been
   reinvested in the fund.

 INVESTMENT POLICIES AND PRACTICES
 ----------------------------------------------------------
   This section takes a detailed look at some of the types of securities each
   fund may hold in its portfolio and the various kinds of investment practices
   that may be used in day-to-day portfolio management. The funds' investment
   programs are subject to further restrictions and risks described in the
   Statement of Additional Information.
 
   Shareholder approval is required to substantively change a fund's objectives
   and certain investment restrictions noted in the following section as
   "fundamental policies." The managers also follow certain "operating
   policies," which can be changed without shareholder approval. However,
   significant changes are discussed with shareholders in fund reports. Each
   fund adheres to applicable investment restrictions and policies at the time
   it makes an investment. A later change in circumstances will not require the
   sale of an investment if it was proper at the time it was made.
 
   Each fund's holdings of certain kinds of investments cannot exceed maximum
   percentages of total assets, which are set forth in this prospectus. For
   instance, the bond funds are not permitted to invest more than 10% of total
   assets in hybrid instruments. While these restrictions provide a useful level
   of detail about a fund's investment program, investors should not view them
   as an accurate gauge of the potential risk of such investments. For example,
   in a given period, a 5% investment in hybrid instruments could have
   significantly more of an impact on each bond fund's share price than its
   weighting in the portfolio. The net effect of a particular investment depends
   on its volatility and the size of its overall return in relation to the
   performance of all the fund's other investments.
 
   Changes in the funds' holdings, the funds' performance, and the contribution
   of various investments are discussed in the shareholder reports sent to you.
 
  . Fund managers have considerable leeway in choosing investment strategies and
   selecting securities they believe will help each fund achieve its objective.
 
 
 Types of Portfolio Securities
 
   
   In seeking to meet their investment objectives, the funds may invest in any
   type of security or instrument whose investment characteristics are
   consistent with the funds' investment programs. For the bond funds, but not
   the money fund, these investments may include potentially high-risk
   derivatives (described in this section). The following pages describe various
   types of portfolio securities and investment management practices of the
   funds.    
 
   Fundamental policy A fund will not purchase a security if, as a result, with
   respect to 75% of its total assets, more than 5% of its total assets would be
   invested in securities of a single issuer or more than 10% of the voting
   securities
<PAGE>
 
T. ROWE PRICE
   of the issuer would be held by the fund. These limitations do not apply to a
   fund's purchases of securities issued or guaranteed by the U.S. government,
   its agencies, or instrumentalities.
 
   Operating policy (money fund only)  Except as permitted by Rule 2a-7 under
   the Investment Company Act of 1940, the money fund will not purchase a
   security if, as a result, more than 5% of its total assets would be invested
   in securities of a single issuer. Under Rule 2a-7, the 5% limit, among other
   things, does not apply to purchases of U.S. government securities or
   securities subject to certain types of guarantees. Additionally, the fund may
   invest up to 25% of its total assets in the first tier securities (as defined
   by Rule 2a-7) of a single issuer for a period of up to three business days.
 
   Bonds
   A bond is an interest-bearing security -  an IOU - issued by companies or
   governmental units. The issuer has a contractual obligation to pay interest
   at a stated rate on specific dates and to repay principal (the bond's face
   value) on a specified date. An issuer may have the right to redeem or "call"
   a bond before maturity, and the investor may have to reinvest the proceeds at
   lower market rates.
 
   A bond's annual interest income, set by its coupon rate, is usually fixed for
   the life of the bond. Its yield (income as a percent of current price) will
   fluctuate to reflect changes in interest rate levels. A bond's price usually
   rises when interest rates fall, and vice versa, so its yield stays current.
 
   Bonds may be unsecured (backed by the issuer's general creditworthiness only)
   or secured (also backed by specified collateral).
 
   Certain bonds have interest rates that are adjusted periodically. These
   interest rate adjustments tend to minimize fluctuations in the bonds'
   principal values. The maturity of those securities may be shortened under
   certain specified conditions.
 
   Bonds may be designated as senior or subordinated obligations. Senior
   obligations generally have the first claim on a corporation's earnings and
   assets and, in the event of liquidation, are paid before subordinated debt.
 
   Money Market Securities
   The main types of money market securities in which the funds can invest are:
 
  . Commercial paper Unsecured promissory notes that corporations typically
   issue to finance current operations and other expenditures.
 
  . Treasury bills Debt obligations sold at discount and repaid at face value by
   the U.S. Treasury. Bills mature in one year or less and are backed by the
   full faith and credit of the U.S. government.
 
  . Certificates of deposit Receipts for funds deposited at banks that guarantee
   a fixed interest rate over a specified time period.
<PAGE>
 
RUNNING H/F 1
  . Repurchase agreements Contracts, usually involving U.S. government
   securities, that require one party to repurchase securities at a fixed price
   on a designated date.
 
  . Banker's acceptances Bank-issued commitments to pay for merchandise sold in
   the import/export market.
 
  . Agency notes Debt obligations of agencies sponsored by the U.S. government
   that are not backed by the full faith and credit of the United States.
 
  . Medium-term notes Unsecured corporate debt obligations that are continuously
   offered in a broad range of maturities and structures.
 
  . Bank notes Unsecured obligations of a bank that rank on an equal basis with
   other kinds of deposits but do not carry FDIC insurance.
 
   Derivatives
   A derivative is a financial instrument whose value is derived from an
   underlying security, such as a stock or bond, or from a market benchmark such
   as an interest rate index. Many types of investments representing a wide
   range of potential risks and rewards are derivatives, including conventional
   instruments such as callable bonds, futures, and options, as well as more
   exotic investments such as stripped mortgage securities and structured notes.
   Investment managers have used derivatives for many years.
 
   We invest in derivatives only if the expected risks and rewards are
   consistent with each fund's objective, policies, and overall risk profile
   described in this prospectus. We use derivatives in situations where they may
   enable each fund to increase yield, hedge against a decline in principal,
   invest in other asset classes more efficiently and at a lower cost, or adjust
   duration.
 
   The bond funds will not invest in any high-risk, highly leveraged derivative
   that we believe would cause the portfolios to be more volatile than 1) an
   intermediate-term investment-grade bond for the Limited-Term Bond Fund; or 2)
   a long-term investment-grade bond for the GNMA Fund.
 
   Asset-Backed Securities
   An underlying pool of assets, such as credit card or automobile trade
   receivables or corporate loans or bonds, backs these bonds and provides the
   interest and principal payments to investors. On occasion, the pool of assets
   may also include a swap obligation, which is used to change the cash flows on
   the underlying assets. As an example, a swap may be used to allow floating
   rate assets to back a fixed rate obligation. Credit quality depends primarily
   on the quality of the underlying assets, the level of credit support, if any,
   provided by the issuer, and the credit quality of the swap counterparty, if
   any. The underlying assets (i.e., loans) are subject to prepayments, which
   can shorten the securities' weighted average life and may lower their return.
   The value of these securities also may
<PAGE>
 
T. ROWE PRICE
   change because of actual or perceived changes in the creditworthiness of the
   originator, the servicing agent, the financial institution providing the
   credit support, or the swap counterparty. There is no limit on each fund's
   investment in these securities.
 
   Mortgage-Backed Securities (bond funds)
   
   The funds may invest in a variety of mortgage-backed securities, which
   include:    
 
  . GNMA Certificates GNMA certificates evidence interests in a pool of
   underlying mortgages with a maximum life of 15 or 30 years. However, due to
   both scheduled and unscheduled principal payments, GNMA certificates have a
   shorter average life and, therefore, less principal volatility than a
   comparable 30-year bond. Since prepayment rates vary widely, it is not
   possible to accurately predict the average life of a particular GNMA pool.
   However, it is standard industry practice to treat new issues of GNMA
   certificates as 30-year mortgage-backed securities having an average life of
   no greater than 12 years. Because the expected average life is a better
   indicator of the maturity characteristics of GNMA certificates, principal
   volatility and yield may be more comparable to 10-year Treasury bonds.
 
  . GNMA Project Pass-Through Securities These securities are issued by GNMA for
   multifamily projects, i.e., low to moderate income housing, nursing homes,
   apartment rehabilitation, housing for the elderly or handicapped, and the
   like. Unlike GNMA "modified pass-through certificates," these bonds provide
   call protection for a term stated in the issue. The project loans can be made
   to either private enterprise or nonprofit groups. There are penalties
   assessed for prepayments during the call-protected period, creating a
   disincentive for early prepayment. These bonds incorporate the same
   standardized procedures as single-family pass-through certificates, and full
   and timely payment of principal and interest is guaranteed by GNMA.
 
   Operating policy The GNMA Fund will invest at least 65% of its assets in GNMA
   mortgage-backed securities.
 
  . Collateralized Mortgage Obligations (CMOs) CMOs are debt securities that are
   fully collateralized by a portfolio of mortgages or mortgage-backed
   securities. All interest and principal payments from the underlying mortgages
   are passed through to the CMOs in such a way as to create, in most cases,
   more definite maturities than is the case with the underlying mortgages. CMOs
   may pay fixed or variable rates of interest, and certain CMOs have priority
   over others with respect to the receipt of prepayments.
 
   Operating policy The Limited-Term Bond and GNMA Funds may invest up to 20%
   and 30% of their assets, respectively, in CMOs.
 
  . Stripped Mortgage Securities Stripped mortgage securities (a type of
   potentially high-risk derivative) are created by separating the interest and
   principal payments
<PAGE>
 
RUNNING H/F 1
   generated by a pool of mortgage-backed securities or a CMO to create
   additional classes of securities. Generally, one class receives only interest
   payments (IOs), and another receives principal payments (POs). Unlike with
   other mortgage-backed securities and POs, the value of IOs tends to move in
   the same direction as interest rates. The funds can use IOs as a hedge
   against falling prepayment rates (interest rates are rising) and/or a bear
   market environment. POs can be used as a hedge against rising prepayment
   rates (interest rates are falling) and/or a bull market environment. IOs and
   POs are acutely sensitive to interest rate changes and to the rate of
   principal prepayments.
 
   A rapid or unexpected increase in prepayments can severely depress the price
   of IOs, while a rapid or unexpected decrease in prepayments could have the
   same effect on POs. These securities are very volatile in price and may have
   lower liquidity than most other mortgage-backed securities. Certain
   non-stripped CMOs may also exhibit these qualities, especially those that pay
   variable rates of interest that adjust inversely with, and more rapidly than,
   short-term interest rates. In addition, if interest rates rise rapidly and
   prepayment rates slow more than expected, certain CMOs, in addition to losing
   value, can exhibit characteristics of longer-term securities and become more
   volatile. There is no guarantee the funds' investments in CMOs, IOs, or POs
   will be successful, and the funds' total returns could be adversely affected
   as a result.
 
   Operating policy The bond funds may invest up to 10% of their total assets in
   stripped mortgage securities.
 
   Hybrid Instruments (bond funds)
   These instruments (a type of potentially high-risk derivative) can combine
   the characteristics of securities, futures, and options. For example, the
   principal amount or interest rate of a hybrid could be tied (positively or
   negatively) to the price of some commodity, currency, or securities index or
   another interest rate (each a "benchmark"). Hybrids can be used as an
   efficient means of pursuing a variety of investment goals, including currency
   hedging, duration management, and increased total return. Hybrids may not
   bear interest or pay dividends. The value of a hybrid or its interest rate
   may be a multiple of a benchmark and, as a result, may be leveraged and move
   (up or down) more steeply and rapidly than the benchmark. These benchmarks
   may be sensitive to economic and political events, such as commodity
   shortages and currency devaluations, which cannot be readily foreseen by the
   purchaser of a hybrid. Under certain conditions, the redemption value of a
   hybrid could be zero. Thus, an investment in a hybrid may entail significant
   market risks that are not associated with a similar investment in a
   traditional, U.S. dollar-denominated bond that has a fixed principal amount
   and pays a fixed rate or floating rate of interest. The purchase of hybrids
   also exposes the funds to the credit risk of the issuer of the hybrid. These
   risks may cause significant fluctuations in the net asset value of the funds.
<PAGE>
 
T. ROWE PRICE
  . Hybrids can have volatile prices and limited liquidity, and their use by the
   funds may not be successful.
 
   Operating policy The bond funds may invest up to 10% of their total assets in
   hybrid instruments.
 
   High-Yield, High-Risk Investing (Limited-Term Bond Fund)
   The total return and yield of lower-quality (high-yield, high-risk) bonds,
   commonly referred to as "junk," can be expected to fluctuate more than the
   total return and yield of higher-quality bonds. Junk bonds (those rated below
   BBB or in default) are regarded as predominantly speculative with respect to
   the issuer's ability to meet principal and interest payments. Successful
   investment in lower-medium- and low-quality bonds involves greater investment
   risk and is highly dependent on T. Rowe Price's credit analysis. A real or
   perceived economic downturn, or rising interest rates, could cause a decline
   in high-yield bond prices by lessening the ability of issuers to make
   principal and interest payments. These bonds are often thinly traded and can
   be more difficult to sell and value accurately than high-quality bonds.
   Because objective pricing data may be less available, judgment may play a
   greater role in the valuation process.
 
   Operating policy The Limited-Term Bond Fund will not purchase a non-
   investment-grade debt security (or junk bond) if immediately after such
   purchase the fund would have more than 10% of its total assets invested in
   such securities.
 
   Private Placements
   These securities are sold directly to a small number of investors, usually
   institutions. Unlike public offerings, such securities are not registered
   with the SEC. Although certain of these securities may be readily sold, for
   example, under Rule 144A, others may be illiquid, and their sale may involve
   substantial delays and additional costs.
 
   Operating policy  The bond funds may invest up to 15% of their net assets
   (10% for the money fund) in illiquid securities.
 
   Foreign Securities (Cash Reserves and Limited-Term Bond Funds)
   The Limited-Term Bond Fund may invest in foreign securities, including
   nondollar-denominated securities traded outside of the U.S. The Cash Reserves
   and Limited-Term Bond Funds may invest without limitation in
   dollar-denominated securities of foreign issuers. Such investments increase a
   portfolio's diversification and may enhance return, but they also involve
   some special risks such as exposure to potentially adverse local political
   and economic developments; nationalization and exchange controls; potentially
   lower liquidity and higher volatility; possible problems arising from
   accounting, disclosure, settlement, and
<PAGE>
 
RUNNING H/F 1
   regulatory practices that differ from U.S. standards; and the chance that
   fluctuations in foreign exchange rates will decrease the investment's value
   (favorable changes can increase its value). To the extent the funds invest in
   developing countries, these risks are increased.
 
   Operating policy The Limited-Term Bond and Cash Reserves Funds may invest
   without limitation in U.S. dollar-denominated debt securities of foreign
   issuers, foreign branches of U.S. banks, and U.S. branches of foreign banks.
   The Limited-Term Bond Fund may invest up to 10% of its total assets
   (excluding reserves) in non-U.S. dollar-denominated fixed income securities
   principally traded in financial markets outside the U.S.
 
 
 Types of Management Practices
 
   Reserve Position (bond funds)
   Each fund will hold a certain portion of its assets in money market reserves.
   Each fund's reserve position is expected to consist primarily of shares of
   one or more T. Rowe Price internal money market funds. Short-term,
   high-quality U.S. and foreign dollar-denominated money market securities,
   including repurchase agreements, may also be held. For temporary, defensive
   purposes, the funds may invest without limitation in money market reserves.
   The effect of taking such a position is that the fund may not achieve its
   investment objective. The reserve position provides flexibility in meeting
   redemptions, expenses, and the timing of new investments and can serve as a
   short-term defense during periods of unusual market volatility.
 
   Borrowing Money and Transferring Assets
   Each fund can borrow money from banks and other Price funds as a temporary
   measure for emergency purposes, to facilitate redemption requests, or for
   other purposes consistent with each fund's investment objective and program.
   Such borrowings may be collateralized with fund assets, subject to
   restrictions.
 
   Fundamental policy  Borrowings may not exceed 33/1//\\/3/\\% of total fund
   assets.
 
   Operating policy  Each fund may not transfer as collateral any portfolio
   securities except as necessary in connection with permissible borrowings or
   investments, and then such transfers may not exceed 33/1//\\/3/\\% of the
   fund's total assets. Each fund may not purchase additional securities when
   borrowings exceed 5% of total assets.
 
   Futures and Options (bond funds)
   
   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    
<PAGE>
 
   
T. ROWE PRICE                                     
   predetermined price in the future. Each fund may buy and sell futures and
   options contracts for any number of reasons, including: to manage its
   exposure to changes in interest rates, bond prices, and foreign currencies;
   as an efficient means of adjusting its overall exposure to certain markets;
   in an effort to enhance income; to protect the value of portfolio securities;
   as a cash management tool; and to adjust portfolio duration. The 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; their
   prices can be highly volatile. Using them could lower each fund's total
   return, and the potential loss from the use of futures can exceed each fund's
   initial investment in such contracts.
 
   Operating policies  Futures: Initial margin deposits and premiums on options
   used for non-hedging purposes will not equal more than 5% of each fund's net
   asset value. Options on securities: The total market value of securities
   against which each fund writes call or put options may not exceed 25% of its
   total assets. Each fund will not commit more than 5% of its total assets to
   premiums when purchasing call or put options.
 
   Interest Rate Swaps (bond funds)
   The funds may enter into various interest rate transactions (a type of
   potentially high-risk derivative investment), such as interest rate swaps and
   the purchase or sale of interest rate caps, collars, and floors, to preserve
   a return or spread on a particular investment or portion of its portfolio, to
   create synthetic securities, or to structure transactions designed for other
   purposes.
 
   Operating policy  The bond funds may invest up to 10% of their total assets
   in interest rate swaps.
 
   Managing Foreign Currency Risk (Limited-Term Bond Fund)
   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."
   The 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 the 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 the fund's total return could be reduced.
 
   Operating policy The Limited-Term Bond Fund will not commit more than 10% of
   its total assets to forward currency contracts.

RUNNING H/F 1
   Lending of Portfolio Securities
   Like other mutual funds, each fund 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, each fund could experience delays in recovering its securities
   and possibly capital losses.
 
   Fundamental policy  The value of loaned securities may not exceed
   33/1//\\/3/\\% of total fund assets.
 
   When-Issued Securities (all funds) and Forwards (bond funds)
   The funds may purchase securities on a when-issued or delayed delivery basis
   or may purchase or sell securities on a forward commitment basis. There is no
   limit on each fund's investment in these securities. The price of these
   securities is fixed at the time of the commitment to buy, but delivery and
   payment can take place a month or more later. During the interim period, the
   market value of the securities can fluctuate, and no interest accrues to the
   purchaser. At the time of delivery, the value of the securities may be more
   or less than the purchase or sale price. To the extent each fund remains
   fully or almost fully invested (in securities with a remaining maturity of
   more than one year) at the same time it purchases these securities, there
   will be greater fluctuations in the fund's net asset value than if the fund
   did not purchase them.
 
   Portfolio Turnover (bond funds)
   Although the funds will not generally trade for short-term profits,
   circumstances may warrant a sale without regard to the length of time a
   security was held. A high turnover rate may increase transaction costs and
   result in additional taxable gains. The Limited-Term Bond and GNMA Funds'
   annualized portfolio turnover rates for the fiscal years ended October 31 are
   listed in Table 5.

   Bond Ratings and High-Yield Bonds
   The credit quality of most bond issues is evaluated by rating agencies such
   as Moody's and Standard & Poor's on the basis of the issuer's ability to meet
   all required interest and principal payments. The highest ratings are
   assigned to issuers perceived to be the best credit risks. T. Rowe Price
   research analysts also evaluate all portfolio holdings of each fund,
   including those rated by outside agencies. Other things being equal,
   lower-rated bonds have higher yields due to greater risk. High-yield bonds,
   also called "junk" bonds, are those rated below BBB.

   Table 6 shows the rating scale used by the major rating agencies, and Table 7
   provides an explanation of quality ratings. T. Rowe Price considers publicly
   available ratings but emphasizes its own credit analysis when selecting
   investments.

 Year 2000 Processing Issue
 
   Many computer programs 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 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, organizations, governmental entities, and markets in which the T.
   Rowe Price funds invest will be affected by the Year 2000 issue, but at this
   time the funds cannot predict the degree of impact. For funds that invest in
   foreign markets, especially emerging markets, it is possible foreign
   companies and

   markets will not be as prepared for Year 2000 as domestic companies and
   markets. To the extent the effect of Year 2000 is negative, a fund's returns
   could be reduced.
 
 
 
 FINANCIAL HIGHLIGHTS
 ----------------------------------------------------------
   Table 8, 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 fund's financial statements, which are
   included in its annual report and are incorporated by reference into the
   Statement of Additional Information (available upon request). The total
   returns in the table represent the rate that an investor would have earned or
   lost on an investment in each fund (assuming reinvestment of all dividends
   and distributions). The financial statements in the annual report were
   audited by the funds' independent accountants, PricewaterhouseCoopers LLP.

(3) to refuse any purchase or exchange order; (4) to cancel or rescind any
purchase or exchange order (including, but not limited to, orders deemed to
result in excessive trading, market timing, fraud, or 5% ownership) upon notice
to the shareholder within five business days of the trade or if the written

to freeze any account and suspend account services when notice has been received
of a dispute between the registered or beneficial account owners or there is
reason to believe a fraudulent transaction may occur; (6) to otherwise modify

 ABOUT THE FUNDS
                                        1
 FUND, MARKET, AND RISK CHARACTERISTICS: WHAT TO EXPECT
 ----------------------------------------------------------
   To help you decide whether these funds are appropriate for you, this section
   reviews their investment objectives, strategies, and potential risks.
 
 
 What is each fund's objective?
 
   Municipal Money Market Fund  The fund seeks preservation of capital and
   liquidity and, consistent with these, the highest possible current income
   exempt from federal income taxes.
 
   Municipal Intermediate Fund  The fund seeks the highest level of income
   exempt from federal income taxes consistent with moderate price fluctuation.
 
   Municipal Income Fund  The fund seeks a high level of income exempt from
   federal income taxes.
 
 
 What is each fund's principal investment strategy?
 
   Municipal Money Market Fund  The fund, which is managed to provide a stable
   share price of $1.00, invests in high-quality municipal securities whose
   income is expected to be exempt from federal income taxes. The fund's
   weighted average maturity will not exceed 90 days, and its yield will
   fluctuate with changes in short-term interest rates.
 
   In selecting securities, fund managers may examine the relationships among
   yields on various types and maturities of money market securities in the
   context of their outlook for interest rates. For example, if we expect rates
   to fall, longer maturities, which typically have higher yields than shorter
   maturities, may be purchased to try to preserve the fund's income level.
   Conversely, shorter maturities may be favored if rates are expected to rise.
 
   
   Municipal Intermediate Fund  We will invest at least 65% of total assets in
   investment-grade tax-exempt securities. There are no maturity limitations on
   individual securities, but the fund's weighted average effective maturity
   will normally range between five and 10 years. Targeting effective maturity
   gives the fund manager additional flexibility. At least 90% of the fund's
   portfolio will consist of investment-grade tax-exempt securities rated in the
   four highest credit categories (AAA, AA, A, BBB) by at least one national
   rating agency or the equivalent from T. Rowe Price when other ratings are not
   available. To enhance income, we may invest up to 10% of the fund's total
   assets in below-investment-grade "junk" bonds, including those with the
   lowest ratings. The fund's income should be higher than the Money Market
   Fund's, but its share price will vary.    
<PAGE>
 
T. ROWE PRICE
   Within this broad structure, investment decisions reflect the manager's
   outlook for interest rates and the economy as well as the prices and yields
   of various securities. For example, if we expect rates to fall, the manager
   may buy longer-term securities to provide higher yield and appreciation
   potential. And if, for instance, our economic outlook is positive, the
   manager may take advantage of the 10% "basket" for noninvestment-grade bonds.
 
   
   Municipal Income Fund  We will invest at least 65% of total assets in
   long-term, investment-grade tax-exempt bonds rated from AAA to BBB by at
   least one national rating agency or rated the equivalent by T. Rowe Price if
   other ratings are not available. To enhance income, we may invest up to 20%
   of the fund's total assets in noninvestment-grade "junk" bonds. We may buy
   securities of any maturity, and we expect the fund's weighted average
   maturity to be 15 years or longer. The fund's income should be higher than
   the Intermediate Fund's, but its share price should fluctuate more.
 
  . A significant portion of each fund's assets may be invested in securities
   subject to the alternative minimum tax.
 
   The fund manager decides to buy or sell different types of securities based
   on the same criteria that apply to the Intermediate Fund, except that the
   average maturities in this fund will be longer and the component of
   noninvestment-grade bonds may go as high as 20%.

   The Intermediate and Income Funds may use derivatives to manage interest rate
   risk.
 
   The funds may sell holdings for a variety of reasons, such as to adjust a
   portfolio's average maturity or quality or to shift assets into
   higher-yielding securities.

   Policies and Practices section.
 
 
 What are the main risks of investing in the funds?
 
   Municipal Money Market Fund  Since money market funds are managed to maintain
   a constant $1.00 share price, they should have little risk of principal loss.
   However, there is no assurance the fund will avoid principal losses if fund
   hold-

ABOUT THE FUNDS
   ings default or interest rates rise sharply in an unusually short period. In
   addition, the fund's yield will vary; it is not fixed for a specific period
   like the yield on a bank certificate of deposit. This should be an advantage
   when interest rates are rising but not when rates are falling. An investment
   in the fund is not insured or guaranteed by the Federal Deposit Insurance
   Corporation (FDIC) or any other government agency. Although the fund seeks to
   preserve the value of your investment at $1.00 per share, it is possible to
   lose money by investing in the fund.
 
   Municipal Intermediate Fund and Municipal Income Fund  These funds are
   subject to the usual risks of fixed income investing:
 
   
  . Interest rate risk  This is the decline in bond prices that accompanies a
   rise in the overall level of interest rates, as shown in Table 5 in this
   section. It is the major source of risk for investors in these two funds.
   Because shorter-term bond funds are less sensitive to interest rate increases
   or decreases than longer-term bond funds, price volatility for the
   Intermediate Fund is expected to be lower than for the Income Fund. However,
   by targeting effective maturity, the Intermediate Fund could experience
   greater volatility than if it focused on a stated maturity or maturity range.
 
  . Credit risk  This is the chance that any of the funds' holdings will have
   their credit ratings downgraded or will default (fail to make scheduled
   interest or principal payments), potentially reducing the fund's income level
   and share price. While the funds will focus on investment-grade bonds,
   holdings of medium- and lower-quality securities are more susceptible to
   adverse economic conditions. The funds' investments in junk bonds should, and
   some of their BBB securities may also, be regarded as speculative. Finally,
   adverse developments in a particular state could result in price declines for
   a fund with significant investments in that state.    
 
  . Political risk  This is the risk that a significant restructuring of federal
   income tax rates, or even serious discussion of the issue in Congress, could
   cause municipal bond prices to fall. The value of tax-exempt income strongly
   influences the demand for municipal bonds, and lower tax rates would reduce
   their advantage.
 
   
  . Derivatives risk  To the extent the funds use these instruments, they may be
   exposed to additional volatility and potential losses.    
 
   As with any mutual fund, there can be no guarantee the funds will achieve
   their objectives.
 
  . The yield of each fund will fluctuate with changing market conditions and
   interest rate levels. The bond funds' share prices will fluctuate as interest
   rates change, so when you sell your shares, you may lose money.

 How can I tell which fund is most appropriate for me?
 
   
   Consider your investment goals, your time horizon for achieving them, and
   your tolerance for risk. The funds can be used to generate income or to
   diversify a stock portfolio. The higher your tax bracket, the more likely
   tax-exempt securities are appropriate. If a Summit Municipal Fund's
   tax-exempt yield is higher than the after-tax yield on a taxable bond or
   money fund, and you can meet the $25,000 minimum for initial purchases, the
   funds could be appropriate for you. Use the table entitled Differences Among
   Funds, which summarizes each fund's main characteristics, to help choose a
   fund (or funds) for your particular needs. For example, only the money fund
   is designed to provide principal stability, which makes it a good choice for
   you if the stability and accessibility of your investment are more important
   than the opportunity for higher income or total return. However, if you are
   investing for the highest possible income and can tolerate some price
   fluctuation, you should consider a longer-term bond fund. The funds are not
   appropriate for tax-deferred accounts, such as IRAs.    
 
  . The bond funds should not represent your complete investment program or be
   used for short-term trading purposes.

 OTHER INFORMATION ABOUT THE FUNDS
 ----------------------------------------------------------
 
 What are the funds' potential rewards?
 
   
   The regular income dividends you receive from the funds should be exempt from
   federal income taxes, and your state may not tax that portion of each fund's
   income earned on the state's own obligations (if any). Lower expenses enable
   the funds to pay higher dividends.    
 
  . Municipal Money Market Fund  offers a relatively secure, liquid investment
   for money you may need for occasional or unexpected expenses and for money
   awaiting investment in longer-term bond or stock funds. In addition to
   preserving capital, the fund seeks to provide the highest possible tax-exempt
   income available from low-risk, short-term municipal securities.
 
  . Municipal Intermediate Fund's  income level should generally be above that
   of the money market fund but lower than that of the Municipal Income Fund.
   Its
<PAGE>
 
ABOUT THE FUNDS
   share price should fluctuate less than that of a long-term bond fund. By
   focusing on investment-grade securities, the fund's credit risk should be
   reduced.
 
  . Municipal Income Fund  should provide the highest income of the three funds
   and also the greatest potential for price appreciation when interest rates
   fall. By the same token, however, its price will decline the most if rates
   should rise. Investors in the fund should have a relatively long time horizon
   to ride out the ups and downs of interest rate cycles.
 
 
 How do the Summit Funds achieve their low-cost advantage?
 
   The advantage reflects their more favorable ratio of expenses to assets. The
   $25,000 initial purchase requirement means that the average account balance
   in each Summit Fund is high. Since shareholder recordkeeping costs - a
   substantial portion of fund expenses - are basically the same for all sizes
   of accounts, a fund with larger account balances can spread the expenses over
   more investment dollars, achieving a low overall expense ratio. Expenses are
   deducted from fund assets before dividends are paid, as explained previously,
   so lower costs result in higher dividends for Summit Fund shareholders.
 
 
 How does the portfolio manager try to reduce risk?
 
   Consistent with each fund's objective, the portfolio manager uses various
   tools to try to reduce risk and increase total return, including:
 
  . Diversification of assets to reduce the impact of a single holding on a
   fund's net asset value.
 
  . Thorough credit research by our own analysts.
 
  . Adjustment of fund duration to try to reduce the drop in price when interest
   rates rise or to benefit from the rise in price when rates fall. Duration is
   a measure of a fund's sensitivity to interest rate changes.
 
 
 Is there other information I can review before making a decision?
 
   
   Investment Policies and Practices in Section 3 discusses various types of
   portfolio securities the funds may purchase as well as types of management
   practices the funds may use.    
 
 
 Some characteristics of municipal securities
 
 
 Who issues municipal securities?
 
   State and local governments and governmental authorities sell notes and bonds
   (usually called "municipals") to pay for public projects and services.
<PAGE>
 
T. ROWE PRICE
 Who buys municipal securities?
 
   Individuals are the primary investors, and a principal way they invest is
   through mutual funds. Prices of municipals may be affected by major changes
   in cash flows of money into or out of municipal funds. For example,
   substantial and sustained redemptions from municipal bond funds could result
   in lower prices for these securities.
 
 
 What is tax-free about municipal bonds and bond funds?
 
   The regular income dividends you receive from the fund should be exempt from
   regular federal income taxes. In addition, your state may not tax that
   portion of the fund's income earned on the state's own obligations (if any).
   However, capital gains distributed by the funds are taxable to you. (See
   Useful Information on Distributions and Taxes for details.)
 
  . Municipal securities are also called "tax-exempts" because the interest
   income they provide is usually exempt from federal income taxes.
 
 
 Is interest income from municipal issues always exempt from federal taxes?
 
   
   No. Since 1986 income from so-called "private activity" municipals has been
   subject to the federal alternative minimum tax (AMT). For instance, some
   bonds financing projects such as airports, stadiums, and student loan
   programs fall into this category. These bonds carry higher yields than
   regular municipals. Shareholders subject to the AMT must include income
   derived from private activity bonds in their AMT calculation. Relatively few
   taxpayers are required to pay the tax. The funds will seek to invest a
   significant portion of their assets in municipals subject to the AMT in order
   to enhance yield. The portion of income subject to the AMT will be reported
   annually to shareholders. (Please see Distributions and Taxes - Taxes on Fund
   Distributions.)    
 
   Additionally, under highly unusual circumstances, the IRS may determine that
   a bond issued as tax-exempt should in fact be taxable. If a fund were to hold
   such a bond, the fund could have to distribute taxable income or reclassify
   as taxable income previously distributed as tax-free.
 
 
 Why are yields on municipals usually below those on otherwise comparable
 taxable securities?
 
   Since the income provided by most municipals is exempt from federal taxation,
   investors are willing to accept lower yields on a municipal bond than on an
   otherwise similar (in quality and maturity) taxable bond.
 
 
 How can I tell if a tax-free or taxable fund is suitable for me?
 
   
   The primary factor is your expected federal income tax rate. The higher your
   tax bracket, the more likely tax-exempts will be appropriate. If a municipal
   fund's tax-exempt yield is higher than the after-tax yield on a taxable bond
   or    
<PAGE>
 
   
ABOUT THE FUNDS                                   
   money fund, then your income will be higher in the municipal fund. To find
   what a taxable fund would have to yield to equal the yield on a municipal
   fund, divide the municipal fund's yield by one minus your tax rate. For quick
   reference, the next table shows a range of taxable-equivalent yields.

 What are the major differences between money market and bond funds?
 
  . Price  Bond funds have fluctuating share prices. Money market funds are
   managed to maintain a stable share price.
 
  . Maturity  Short- and intermediate-term bond funds have longer average
   maturities (from one to 10 years) than money market funds (90 days or less).
   Longer-term bond funds have the longest average maturities (10 years or
   more).
 
  . Income  Short- and intermediate-term bond funds typically offer more income
   than money market funds and less income than longer-term bond funds.
 
 
 
 SOME BASICS OF FIXED INCOME INVESTING
 ----------------------------------------------------------
 
 Is a fund's yield fixed or will it vary?
 
   It will vary. The yield is calculated every day by dividing a fund's net
   income per share, expressed at annual rates, by the share price. Since both
   income and share price will fluctuate, a fund's yield will also vary.
   (Although money fund prices are stable, income is variable.)
 
 
 Is yield the same as total return?
 
   Not for bond funds. The total return reported for a fund is the result of
   reinvested distributions (income and capital gains) and the change in share
   price for a given time period. Income is always a positive contributor to
   total return and
<PAGE>
 
T. ROWE PRICE
   can enhance a rise in share price or serve as an offset to a drop in share
   price. Since money funds are managed to maintain a stable share price, their
   yield and total return should be the same.
 
 
 What is credit quality and how does it affect yield?
 
   Credit quality refers to a bond issuer's expected ability to make all
   required interest and principal payments on time. Because highly rated
   issuers represent less risk, they can borrow at lower interest rates than
   less creditworthy issuers. Therefore, a fund investing in high-quality
   securities should have a lower yield than an otherwise comparable fund
   investing in lower-quality securities.
 
 
 What is meant by a bond fund's maturity?
 
   
   Every bond has a stated maturity date when the issuer must repay the bond's
   entire principal value to the investor. However, many bonds are "callable,"
   meaning their principal can be repaid earlier, on or after specified call
   dates. Bonds are most likely to be called when interest rates are falling
   because the issuer can refinance at a lower rate, just as a homeowner
   refinances a mortgage. In that environment, a bond's "effective maturity" is
   usually its nearest call date.    
 
   A bond mutual fund has no real maturity, but it does have a weighted average
   maturity and an average effective maturity. This number is an average of the
   stated or effective maturities of the underlying bonds, with each bond's
   maturity "weighted" by the percentage of fund assets it represents. Funds
   that target effective maturities normally use the effective, rather than
   stated, maturities of the bonds in the portfolio when computing the average.
   This provides additional flexibility in portfolio management but, all else
   being equal, could result in higher volatility than a fund targeting a stated
   maturity or maturity range.
 
 
 What is meant by a bond fund's duration?
 
   Duration is a calculation that seeks to measure the price sensitivity of a
   bond or a bond fund to changes in interest rates. It measures this
   sensitivity more accurately than maturity because it takes into account the
   time value of cash flows generated over the bond's life. Future interest and
   principal payments are discounted to reflect their present value and then are
   multiplied by the number of years they will be received to produce a value
   expressed in years - the duration. Effective duration takes into account call
   features and sinking fund payments that may shorten a bond's life.
 
   Since duration can also be computed for bond funds, you can estimate the
   effect of interest rates on share price by multiplying fund duration by an
   expected change in interest rates. For example, the price of a bond fund with
   a duration of five years would be expected to fall approximately 5% if rates
   rose by one percentage point. (T. Rowe Price bond fund shareholder reports
   show duration.)

ABOUT THE FUNDS
 How is a municipal's price affected by changes in interest rates?
 
   
   When interest rates rise, a bond's price usually falls, and vice versa. In
   general, the longer a bond's maturity, the greater the price increase or
   decrease in response to a given change in rates, as shown in Table 5.

 changes of any T. Rowe Price fund.
 
 
 Do money market securities react to changes in interest rates?
 
   Yes. As interest rates change, the prices of money market securities
   fluctuate, but changes are usually small because of their very short
   maturities. Investments are typically held until maturity in a money fund to
   help the fund maintain a $1.00 share price.

 PRICING SHARES AND RECEIVING SALE PROCEEDS
 ----------------------------------------------------------
   Here are some procedures you should know when investing in a T. Rowe Price
   fund.
 
 
 How and when shares are priced
 
   Bond and money funds
   The share price (also called "net asset value" or NAV per share) for each
   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. Current market values are used to price
   bond fund shares. Amortized cost is used to value money fund securities.
 
   
  . 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 may
   differ for institutional 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
 
  . When filling out the New Account Form, you may wish to give yourself the
   widest range of options for receiving proceeds from a sale.
 
   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
<PAGE>
 
ABOUT YOUR ACCOUNT
   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 each 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 are exchanging into
   another fund, your purchase order will be priced at that fund's NAV on the
   fifth business day after the exchange. If you are exchanging into a bond or
   money fund, your new investment will not begin to earn dividends until the
   sixth business day.    
 
  . If for some reason we cannot accept your request to sell shares, we will
   contact you.
 
 
 
 USEFUL INFORMATION ON DISTRIBUTIONS AND TAXES
 ----------------------------------------------------------
  . 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.
 
   Income dividends
  . Bond funds declare 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.
 
  . Dividends are paid 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
<PAGE>
 
T. ROWE PRICE
   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.
 
  . Money funds declare income dividends daily to shareholders of record as of
   12 noon ET on that day. Wire purchase orders received before 12 noon ET
   receive the dividend for that day. Other purchase orders receive the dividend
   on the next business day after payment has been received.
 
   Capital gains
  . Since money funds are managed to maintain a constant share price, they are
   not expected to make capital gain distributions.
 
  . 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
 
  . You will be sent timely information for your tax filing needs.
 
   Although the regular monthly income dividends you receive from each fund are
   expected to be exempt from federal income taxes, 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.
 
   Note: You must report your total tax-exempt income on IRS Form 1040. The IRS
   uses this information to help determine the tax status of any Social Security
   payments you may have received during the year. For shareholders who receive
   Social Security benefits, the receipt of tax-exempt interest may increase the
   portion of benefits that are subject to tax.
 
   If a fund invests in certain "private activity" bonds, shareholders who are
   subject to the alternative minimum tax (AMT) must include income generated by
   these bonds in their AMT computation. The portion of your fund's income that
   should be included in your AMT calculation, if any, will be reported to you
   in January.
 
   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. If you realize a
   loss on the sale or exchange of fund shares held six months or less, your
   capital loss is reduced by the tax-exempt dividends received on those shares.
<PAGE>
 
ABOUT YOUR ACCOUNT
   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
   In January, you will be sent Form 1099-DIV indicating the tax status of any
   capital gain distributions made to you. This information will also be
   reported to the IRS. A fund's capital gain distributions are generally
   taxable to you for the year in which they were paid. Dividends are expected
   to be tax-exempt.
 
   
   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, and long-term gains on securities held more
   than 12 months are taxed at a maximum rate of 20%. If you realized a loss on
   the sale or exchange of fund shares that you held six months or less, your
   short-term loss will be reclassified to a long-term loss to the extent of any
   long-term capital gain distribution received during the period you held the
   shares.    
 
   A portion of the capital gains realized on the sale of market discount bonds
   with maturities beyond one year may be treated as ordinary income and cannot
   be offset by other capital losses. Therefore, to the extent each fund invests
   in these securities, the likelihood of a taxable gain distribution will be
   increased.
 
  . Distributions are taxable whether reinvested in additional shares or
   received in cash.
 
   Tax effect of buying shares before a capital gain 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. There-
<PAGE>
 
T. ROWE PRICE
   fore, 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
   taxable distributions.
 
 
 
 TRANSACTION PROCEDURES AND SPECIAL REQUIREMENTS
 ----------------------------------------------------------
  . 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 each fund or transfer agent, and the fund
   can redeem shares you own in this or another identically registered T. Rowe
   Price fund as reimbursement. Each 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
 
   
   Holds on immediate redemptions: 10-day hold    
   If you sell shares that you just purchased and paid for by check or ACH
   transfer, the funds 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. If, during the
   clearing period, we receive a check drawn against your bond or money market
   account, it will be returned marked "uncollected." (The 10-day hold does not
   apply to the following: purchases 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 boxes that state 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 or computer are
   genuine; they are not liable for acting on these instructions. If these
   procedures are not followed, it is the opin-    
<PAGE>
 
   
ABOUT YOUR ACCOUNT                                
   ion of certain regulatory agencies that the funds and their agents may be
   liable for any losses that may result from acting on the instructions. 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
 
  . 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 nonmoney fund are
   not exempt); and 2) systematic purchases or redemptions (see Information
   About Your 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.
 
  . 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 $10,000. If your balance
   is below $10,000 for three months or longer, we have the right to close your
   account after giving you 60 days in which to increase your balance.
<PAGE>
 
T. ROWE PRICE
 Signature Guarantees
 
  . 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 Summit Municipal Funds, Inc. (the "corporation") was
   incorporated in Maryland in 1993 and is a "diversified, open-end investment
   company," or mutual fund. Mutual funds pool money received from shareholders
   and invest it to try to achieve specified objectives.
 
   Currently, the corporation consists of three series: the Summit Municipal
   Money Market Fund, the Summit Municipal Intermediate Fund, and the Summit
   Municipal Income Fund, each of which represents a separate class of shares
   and has different objectives and investment policies. Each of the Summit
   Funds was established in 1993.
 
  . Shareholders benefit from T. Rowe Price's 62 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 director 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
   instructions on voting by mail or telephone, or on the Internet.
<PAGE>
 
T. ROWE PRICE
 Who runs the funds?
 
   General Oversight
   
   The corporation is governed by a Board of Directors that meets regularly to
   review each fund's investments, performance, expenses, and other business
   affairs. The Board elects the corporation's officers. The policy of the
   corporation is that a majority of Board members are independent of T. Rowe
   Price Associates, Inc. (T. Rowe Price).    
 
  . All decisions regarding the purchase and sale of fund investments are made
   by T. Rowe Price  -  specifically by each fund's portfolio managers.
 
   Portfolio Management
   Each fund has an Investment Advisory Committee whose chairman has day-to-day
   responsibility for managing the fund and works with the committee in
   developing and executing the fund's investment program. The Investment

   The Management Fee
   
   Each fund pays T. Rowe Price an annual all-inclusive fee based on its average
   daily net assets. The funds calculate and accrue the fee daily. The fees for
   the funds for their most recent fiscal years were 0.45% for the Money Fund
   and 0.50% for the Intermediate and Income Funds.

 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 total
   return figures, which may be compared with various indices, other performance
   measures, or other mutual funds.
 
 
 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
 
   
   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 price at
   the end of the given period. 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.    
 
   For bond funds, the advertised or Securities and Exchange Commission (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.
<PAGE>
 
T. ROWE PRICE
   The money fund may advertise a current yield, reflecting the latest seven-day
   income annualized, or an "effective" yield, which assumes the income has been
   reinvested in the fund.
 
 
 
 INVESTMENT POLICIES AND PRACTICES
 ----------------------------------------------------------
   This section takes a detailed look at some of the types of securities the
   funds may hold in their portfolios and the various kinds of investment
   practices that may be used in day-to-day portfolio management. Each fund's
   investment program is subject to further restrictions and risks described in
   the Statement of Additional Information.
 
   Shareholder approval is required to substantively change a fund's objective
   and certain investment restrictions noted in the following section as
   "fundamental policies." The managers also follow certain "operating
   policies," which can be changed without shareholder approval. However,
   significant changes are discussed with shareholders in fund reports. Each
   fund adheres to applicable investment restrictions and policies at the time
   it makes an investment. A later change in circumstances will not require the
   sale of an investment if it was proper at the time it was made.
 
   The funds' holdings of certain kinds of investments cannot exceed maximum
   percentages of total assets, which are set forth in this prospectus. For
   instance, the bond funds are not permitted to invest more than 10% of total
   assets in residual interest bonds. While these restrictions provide a useful
   level of detail about the funds' investment programs, investors should not
   view them as an accurate gauge of the potential risk of such investments. For
   example, in a given period, a 5% investment in residual interest bonds could
   have significantly more of an impact on a fund's share price than its
   weighting in the portfolio. The net effect of a particular investment depends
   on its volatility and the size of its overall return in relation to the
   performance of all the funds' other investments.
 
   Changes in the funds' holdings, the funds' performance, and the contribution
   of various investments are discussed in the shareholder reports sent to you.
 
  . Fund managers have considerable leeway in choosing investment strategies and
   selecting securities they believe will help each fund achieve its objective.
 
 
 Types of Portfolio Securities
 
   
   In seeking to meet its investment objective, each fund may invest in any type
   of municipal security or instrument whose investment characteristics are
   consistent with its investment program. For the bond funds, but not the money
   fund,

MORE ABOUT THE FUNDS                              
   these investments may include potentially high-risk derivatives (described in
   this section). The following pages describe various types of portfolio
   securities and investment management practices of the funds.
 
   Fundamental policy  Each fund will not purchase a security if, as a result,
   with respect to 75% of its total assets, more than 5% of its total assets
   would be invested in securities of a single issuer, or if more than 10% of
   the outstanding voting securities of the issuer would be held by each fund.
   These limitations do not apply to a fund's purchase of securities issued or
   guaranteed by the U.S. government, its agencies, or instrumentalities.
 
   Operating policy (money fund only)  Except as permitted by Rule 2a-7 under
   the Investment Company Act of 1940, the money fund will not purchase a
   security if, as a result, more than 5% of its total assets would be invested
   in securities of a single issuer. Under Rule 2a-7, the 5% limit, among other
   things, does not apply to purchases of U.S. government securities or
   securities subject to certain types of guarantees. Additionally, the fund may
   invest up to 25% of its total assets in the first tier securities (as defined
   by Rule 2a-7) of a single issuer for a period of up to three business days.
 
   Municipal Securities
   Each fund's assets are invested primarily in various tax-free municipal debt
   securities. The issuers have a contractual obligation to pay interest at a
   stated rate on specific dates and to repay principal (the bond's face value)
   on a specified date or dates. An issuer may have the right to redeem or
   "call" a bond before maturity, and the funds may have to reinvest the
   proceeds at lower rates.
 
   There are two broad categories of municipal bonds. General obligation bonds
   are backed by the issuer's "full faith and credit," that is, its full taxing
   and revenue raising power. Revenue bonds usually rely exclusively on a
   specific revenue source, such as charges for water and sewer service, to
   generate money for debt service.
 
  . In purchasing municipals, the funds rely on the opinion of the issuer's bond
   counsel regarding the tax-exempt status of the investment.
 
   Private Activity Bonds and Taxable Securities
   While income from most municipals is exempt from federal income taxes, the
   income from certain types of so-called private activity bonds (a type of
   revenue bond) may be subject to the alternative minimum tax (AMT). However,
   only persons subject to the AMT pay this tax. Private activity bonds may be
   issued for purposes such as housing or airports or to benefit a private
   company. (Being subject to the AMT does not mean the investor necessarily
   pays this tax. For further information, please see Distributions and Taxes.)
<PAGE>
 
T. ROWE PRICE
   Operating policy  Each fund may invest without limit in bonds subject to the
   AMT.
 
   Operating policy  During periods of abnormal market conditions, for temporary
   defensive purposes, the funds may invest without limit in high-quality,
   short-term securities whose income is subject to federal income tax.
 
   In addition to general obligation and revenue bonds, the funds' investments
   may include, but are not limited to, the following types of securities:
 
   Municipal Lease Obligations
   A lease is not a full faith and credit obligation of the issuer and is
   usually backed only by the borrowing government's unsecured pledge to make
   annual appropriations for lease payments. There have been challenges to the
   legality of lease financing in numerous states and, from time to time,
   certain municipalities have considered not appropriating money for lease
   payments. In deciding whether to purchase a lease obligation, the funds would
   assess the financial condition of the borrower, the merits of the project,
   the level of public support for the project, and the legislative history of
   lease financing in the state. These securities may be less readily marketable
   than other municipals. The funds may also purchase unrated lease obligations.
 
   Securities With "Puts" or Other Demand Features
   Some longer-term municipals give the investor the right to "put" or sell the
   security at par (face value) within a specified number of days following the
   investor's request - usually one to seven days. This demand feature enhances
   a security's liquidity by shortening its effective maturity and enables it to
   trade at a price equal to or very close to par. The money fund typically
   purchases a significant number of these securities. If a demand feature
   terminates prior to being exercised, the funds may be forced to hold the
   longer-term security, which could experience substantially more volatility.
 
   Securities With Credit Enhancements
  . Letters of credit  Letters of credit are issued by a third party, usually a
   bank, to enhance liquidity and ensure repayment of principal and any accrued
   interest if the underlying municipal security should default.
 
  . T. Rowe Price periodically reviews the credit quality of the insurer.
 
  . Municipal Bond Insurance  This insurance, which is usually purchased by the
   bond issuer from a private, nongovernmental insurance company, provides an
   unconditional and irrevocable guarantee that the insured bond's principal and
   interest will be paid when due. Insurance does not guarantee the price of the
   bond or the share price of any fund. The credit rating of an insured bond
   reflects the credit rating of the insurer, based on its claims-paying
   ability.
<PAGE>
 
MORE ABOUT THE FUNDS
   The obligation of a municipal bond insurance company to pay a claim extends
   over the life of each insured bond. Although defaults on insured municipal
   bonds have been low to date and municipal bond insurers have met their
   claims, there is no assurance this will continue. A higher-than-expected
   default rate could strain the insurer's loss reserves and adversely affect
   its ability to pay claims to bondholders, such as the funds. The number of
   municipal bond insurers is relatively small, and not all of them have the
   highest rating.
 
  . Standby Purchase Agreements  A Standby Bond Purchase Agreement (SBPA) is a
   liquidity facility provided to pay the purchase price of bonds that cannot be
   remarketed. The obligation of the liquidity provider (usually a bank) is only
   to advance funds to purchase tendered bonds that cannot be remarketed and
   does not cover principal or interest under any other circumstances. The
   liquidity provider's obligations under the SBPA are usually subject to
   numerous conditions, including the continued creditworthiness of the
   underlying borrower.
 
   Private Placements
   Each fund may seek to enhance its yield through the purchase of private
   placements. These securities are sold through private negotiations, usually
   to institutions or mutual funds, and may have resale restrictions. Their
   yields are usually higher than comparable public securities to compensate the
   investor for their limited marketability.
 
   Operating policy  Each bond fund may invest up to 15% (10% for the money
   fund) of its net assets in illiquid securities, including unmarketable
   private placements.
 
   High-Yield, High-Risk Investing (bond funds)
   The total return and yield of lower-quality (high-yield, high-risk) bonds,
   commonly referred to as "junk," can be expected to fluctuate more than the
   total return and yield of higher-quality bonds. Junk bonds (those rated below
   BBB or in default) are regarded as predominantly speculative with respect to
   the issuer's ability to meet principal and interest payments. Successful
   investment in lower-medium- and low-quality bonds involves greater investment
   risk and is highly dependent on T. Rowe Price's credit analysis. A real or
   perceived economic downturn, or rising interest rates, could cause a decline
   in high-yield bond prices by lessening the ability of issuers to make
   principal and interest payments. These bonds are often thinly traded and can
   be more difficult to sell and value accurately than high-quality bonds.
   Because objective pricing data may be less available, judgment may play a
   greater role in the valuation process.
 
   
   Operating policy  The Intermediate and Income Funds may invest up to 10% and
   20%, respectively, of total assets in below-investment-grade bonds, including
   those with the lowest rating.

T. ROWE PRICE
   Synthetic or Derivative Securities
   
  . Derivatives  A derivative is a financial instrument whose value is derived
   from an underlying security, such as a stock or bond, or from a market
   benchmark such as an interest rate index. Many types of investments
   representing a wide range of potential risks and rewards are derivatives,
   including conventional instruments such as callable bonds, futures, and
   options, as well as more exotic investments such as stripped mortgage
   securities and structured notes. Investment managers have used derivatives
   for many years.    
 
   We invest in derivatives only if the expected risks and rewards are
   consistent with each fund's objective, policies, and overall risk profile
   described in this prospectus. We use derivatives in situations where they may
   enable each fund to increase yield, hedge against a decline in principal,
   invest in other asset classes more efficiently and at a lower cost, or adjust
   duration.
 
   
   The bond funds will not invest in any high-risk, highly leveraged derivative
   that we believe would cause the portfolios to be more volatile than 1) an
   intermediate-term investment-grade bond for the Intermediate Fund; or, 2)  a
   long-term investment-grade bond for the Income Fund.    
 
  . Residual Interest Bonds (bond funds)  (These are a type of potentially
   high-risk derivative.) The income stream provided by an underlying bond is
   divided to create two securities, one short term and one long term. The
   interest rate on the short-term component is reset by an index or auction
   process normally every seven to 35 days. After income is paid on the
   short-term securities at current rates, the residual income goes to the
   long-term securities. Therefore, rising short-term interest rates result in
   lower income for the longer-term portion, and vice versa. The longer-term
   bonds can be very volatile and may be less liquid than other municipals of
   comparable maturity. The funds will invest only in securities deemed
   tax-exempt by a nationally recognized bond counsel, but there is no guarantee
   the interest will be exempt because the IRS has not issued a definitive
   ruling on the matter.
 
   Operating policy  Each bond fund may invest up to 10% of its total assets in
   residual interest bonds.
 
   
  . Participation Interests  This term covers various types of securities
   created by converting fixed rate bonds into short-term, variable rate
   certificates. These securities have been developed in the secondary market to
   meet the demand for short-term, tax-exempt securities. The funds will invest
   only in securities deemed tax-exempt by a nationally recognized bond counsel,
   but there is no guarantee the interest will be exempt because the IRS has not
   issued a definitive ruling on the matter. There is no limit on the amount
   that the funds can invest in these securities.    
<PAGE>
 
MORE ABOUT THE FUNDS
  . Embedded Interest Rate Swaps and Caps (bond funds)  In a fixed rate,
   long-term municipal bond with an interest rate swap attached to it, the
   bondholder usually receives the bond's fixed coupon payment as well as a
   variable rate payment that represents the difference between a fixed rate for
   the term of the swap (which is typically shorter than the bond it is attached
   to) and a variable rate short-term municipal index. The bondholder receives
   excess income when short-term rates remain below the fixed interest rate swap
   rate. If short-term rates rise above the fixed income swap rate, the
   bondholder's income is reduced. At the end of the interest rate swap term,
   the bond reverts to a single fixed coupon payment.
 
   An embedded interest rate cap allows the bondholder to receive payments
   whenever short-term rates rise above a level established at the time of
   purchase. They normally are used to hedge against rising short-term interest
   rates.
 
   Both instruments may be volatile and of limited liquidity, and their use may
   adversely affect a fund's total return.
 
   Operating policy  Each bond fund may invest up to 10% of its total assets in
   embedded interest rate swaps and caps.
 
   Municipal Warrants (bond funds)
   Municipal warrants are essentially call options on municipal bonds. In
   exchange for a premium, they give the purchaser the right, but not the
   obligation, to purchase a municipal bond in the future. The bond funds might
   purchase a warrant to lock in forward supply in an environment where the
   current issuance of bonds is sharply reduced. Like options, warrants may
   expire worthless and they may have reduced liquidity.
 
   Operating policy  Each bond fund may invest up to 2% of its total assets in
   municipal warrants.
 
 
 Types of Management Practices
 
   Reserve Position (bond funds)
   
   Each fund will hold a portion of its assets in short-term, tax-exempt money
   market securities maturing in one year or less. The reserve position provides
   flexibility in meeting redemptions, expenses, and the timing of new
   investments; can help in structuring each fund's weighted average maturity;
   and serves as a short-term defense during periods of unusual market
   volatility. Each fund's reserve position can consist of shares of one or more
   T. Rowe Price internal money market funds as well as short-term,
   investment-grade securities, including tax-exempt commercial paper, municipal
   notes, and short-term maturity bonds. Some of these securities may have
   adjustable, variable, or floating rates. For temporary, defensive purposes,
   each fund may invest without limitation in money market reserves. The effect
   of taking such a position is that the fund may not achieve its investment
   objective.    
<PAGE>
 
T. ROWE PRICE
   When-Issued Securities (all funds) and Forwards (bond funds)
   New issues of municipals are often sold on a "when-issued" basis, that is,
   delivery and payment take place 15 - 45 days after the buyer has agreed to
   the purchase. Some bonds, called "forwards," have longer-than-standard
   settlement dates, typically six to 24 months. When buying these securities,
   each fund will maintain cash or high-grade marketable securities held by its
   custodian equal in value to its commitment for these securities. Each fund
   does not earn interest on when-issued and forward securities until
   settlement, and the value of the securities may fluctuate between purchase
   and settlement. Municipal "forwards" typically carry a substantial yield
   premium to compensate the buyer for their greater interest rate, credit, and
   liquidity risks.
 
   Interest Rate Futures (bond funds)
   
   Futures (a type of potentially high-risk derivative) are often used to manage
   risk because they enable the investor to buy or sell an asset in the future
   at an agreed-upon price. Specifically, the funds may use futures (and options
   on futures) for any number of reasons, including: to hedge against a
   potentially unfavorable change in interest rates and to adjust their exposure
   to the municipal bond market; to protect portfolio value; in an effort to
   enhance income; as a cash management tool; and to adjust portfolio duration.
   The use of futures for hedging and non-hedging purposes may not always be
   successful. Their prices can be highly volatile, using them could lower a
   fund's total return, and the potential loss from their use could exceed a
   fund's initial exposure to such contracts.    
 
   Operating policy  Initial margin deposits on futures and premiums on options
   used for non-hedging purposes may equal up to 5% of a bond fund's net asset
   value.
 
   Borrowing Money and Transferring Assets
   Each fund can borrow money from banks and other Price funds as a temporary
   measure for emergency purposes, to facilitate redemption requests, or for
   other purposes consistent with each fund's investment objective and program.
   Such borrowings may be collateralized with fund assets, subject to
   restrictions.
 
   Fundamental policy  Borrowings may not exceed 33/1//\\/3/\\% of total fund
   assets.
 
   Operating policy  Each fund may not transfer as collateral any portfolio
   securities except as necessary in connection with permissible borrowings or
   investments, and then such transfers may not exceed 33/1//\\/3/\\% of the
   fund's total assets. Each fund may not purchase additional securities when
   borrowings exceed 5% of total assets.
 
   Portfolio Turnover (bond funds)
   
   Each fund generally purchases securities with the intention of holding them
   for investment; however, when market conditions or other circumstances
   warrant, securities may be purchased and sold without regard to the length of
   time held.    
<PAGE>
 
   
MORE ABOUT THE FUNDS                              
   Due to the nature of each fund's investment program, a fund's portfolio
   turnover rate may exceed 100%. Although the funds do not expect to generate
   any taxable income, a high turnover rate may increase transaction costs and
   may affect taxes paid by shareholders to the extent capital gains are
   distributed. The funds' portfolio turnover rates for the previous three
   fiscal years are shown in Table 6.

   Sector Concentration
   
   It is possible that each fund could have a considerable amount of assets (25%
   or more) in securities that would tend to respond similarly to particular
   economic or political developments. An example would be hospital bonds or
   securities of a single state.    
 
   Operating policy  Each fund may invest up to 25% of total assets in
   industrial development bonds of projects in the same industry (such as solid
   waste, nuclear utility, or airlines). Bonds which are refunded with escrowed
   U.S. government securities are not subject to the 25% limitation.
 
   Credit-Quality Considerations
   The credit quality of most bond issues is evaluated by rating agencies such
   as Moody's and Standard & Poor's on the basis of the issuer's ability to meet
   all required interest and principal payments. The highest ratings are
   assigned to issuers perceived to be the best credit risks. T. Rowe Price
   research analysts also evaluate all portfolio holdings of each fund,
   including those rated by outside agencies. Other things being equal,
   lower-rated bonds have higher yields due to greater risk. High-yield bonds,
   also called "junk" bonds, are those rated below BBB.

T. ROWE PRICE
 Year 2000 Processing Issue
 
   Many computer programs 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 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, organizations, governmental entities, and markets in which the T.
   Rowe Price funds invest will be affected by the Year 2000 issue, but at this
   time the funds cannot predict the degree of impact. For funds that invest in
   foreign markets, especially emerging markets, it is possible foreign
   companies and markets will not be as prepared for Year 2000 as domestic
   companies and markets. To the extent the effect of Year 2000 is negative, a
   fund's returns could be reduced.

 FINANCIAL HIGHLIGHTS
 ----------------------------------------------------------
   
   Table 9, 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 fund's financial statements, which are
   included in its annual report and are incorporated by reference into the
   Statement of Additional Information (available upon request). The total
   returns in the table represent the rate that an investor would have earned or
   lost on an investment in each fund (assuming reinvestment of all dividends
   and distributions). The financial statements in the annual report were
   audited by the funds' independent accountants, PricewaterhouseCoopers LLP.

investment minimums; (2) to accept initial purchases by telephone or mailgram;
(3) to refuse any purchase or exchange order; (4) to cancel or rescind any
purchase or exchange order (including, but not limited to, orders deemed to
result in excessive trading, market timing, fraud, or 5% ownership) upon notice
to the shareholder within five business days of the trade or if the written

to freeze any account and suspend account services when notice has been received
of a dispute between the registered or beneficial account owners or there is
reason to believe a fraudulent transaction may occur; (6) to otherwise modify

outstanding shares of the fund, except upon approval of the fund's management.

 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. References to the following are as indicated:

 RISK FACTORS FOR SUMMIT INCOME FUNDS
 -------------------------------------------------------------------------------
   Reference is also made to the sections entitled "Types of Securities" and
   "Portfolio Management Practices" for discussions of the risks associated with
   the investments and practices described therein as they apply to the Fund.
 
   Cash Reserves Fund
 
   
   The Money Fund will limit its purchases of portfolio instruments to those
   U.S. dollar-denominated securities which the Fund's Board of Directors
   determines present minimal credit risk, and which are Eligible Securities as
   defined in Rule 2a-7 under the 1940 Act. Eligible Securities are generally
   securities which have been rated (or whose issuer has been rated or whose
   issuer has comparable securities rated) in one of the two highest short-term
   rating categories (which may include sub-categories) by nationally recognized
   statistical rating organizations or, in the case of any instrument that is
   not so rated, is of comparable high quality as determined by T. Rowe Price
   pursuant to written guidelines established under the supervision of the
   Fund's Board of Directors. In addition, the Fund may treat variable and
   floating rate instruments with demand features as short-term securities
   pursuant to Rule 2a-7 under the 1940 Act.    
 
   There can be no assurance that the Fund will achieve its investment
   objectives or be able to maintain its net asset value per share at $1.00. The
   price of the Fund is not guaranteed or insured, and its yield is not fixed.
   While the Fund invests in high-grade money market instruments, investment in
   the Fund is not without risk even if all portfolio instruments are paid in
   full at maturity. An increase in interest rates could reduce the value of the
   Fund's portfolio investments, and a decline in interest rates could increase
   the value.
 
   Limited-Term Bond Fund
 
   Because of its investment policy, the Fund may or may not be suitable or
   appropriate for all investors. The Fund is not a money market fund and is not
   an appropriate investment for those whose primary objective is principal
   stability. There is risk in all investment. The Fund is designed for the
   investor who seeks to participate in a diversified portfolio of short- and
   intermediate-term investment grade bonds and other debt securities (up to 10%
   of which may be below investment grade) which provide a higher rate of income
   than a money market fund and less risk of capital fluctuation than a
   portfolio of long-term debt securities. The value of the portfolio securities
   of the Fund will fluctuate based upon market conditions. Although the Fund
   seeks to reduce risk by investing in a diversified portfolio, such
   diversification does not eliminate all risk. There can, of course, be no
   assurance that the Fund will achieve these results.
 
   GNMA Fund
 
   The Fund may or may not be suitable or appropriate for all investors. The
   Fund is designed for investors seeking the highest current income and credit
   protection available from investment in securities which are backed by the
   full faith and credit of the U.S. government and other securities rated
   within the highest two credit categories established by a nationally
   recognized public rating agency, or, if unrated, of equivalent quality as
   determined by T. Rowe Price. Consistent with a long-term financial investment
   approach, investors in the Fund should not rely on the Fund for their
   short-term financial needs. The value of the portfolio securities of the Fund
   will fluctuate based upon market conditions. Although the Fund seeks to
   reduce risk by investing in a diversified portfolio, such diversification
   does not eliminate all risk. There can, of course, be no assurance that the
   Fund will achieve these results.
 
   Because they consist of underlying mortgages, GNMA securities may not be an
   effective means of "locking in" long-term interest rates due to the need for
   the Fund to reinvest scheduled and unscheduled principal payments. The
   incidence of unscheduled principal prepayments is also likely to increase in
   mortgage pools owned by the Fund when prevailing mortgage loan rates fall
   below the mortgage rates of the securities underlying the individual pool.
   The effect of such prepayments in a falling rate environment is to (1) cause
   the Fund to reinvest principal payments at the then lower prevailing interest
   rate, and (2) reduce the potential for capital appreciation beyond the face
   amount of the security and adversely affect the return to the Fund.
   Conversely, in a rising interest rate environment such prepayments can be
   reinvested at higher prevailing
 
 
<PAGE>
 
   interest rates which will reduce the potential effect of capital depreciation
   to which bonds are subject when interest rates rise. In addition, prepayments
   of mortgage securities purchased at a premium (or discount) will cause such
   securities to be paid off at par, resulting in a loss (gain) to the Fund. T.
   Rowe Price will actively manage the Fund's portfolio in an attempt to reduce
   the risk associated with investment in mortgage-backed securities.
 
 
                                Debt Obligations
 
   
   Yields on short-, intermediate-, and long-term debt securities are dependent
   on a variety of factors, including the general conditions of the money and
   bond markets, the size of a particular offering, the maturity of the
   obligation, and the credit quality and rating of the issue. Debt securities
   with longer maturities tend to have higher yields and are generally subject
   to potentially greater capital appreciation and depreciation than obligations
   with shorter maturities and lower yields. The market prices of debt
   securities usually vary, depending upon available yields. An increase in
   interest rates will generally reduce the value of portfolio debt securities,
   and a decline in interest rates will generally increase the value of
   portfolio debt securities. The ability of the Fund to achieve its investment
   objective is also dependent on the continuing ability of the issuers of the
   debt securities in which the Fund invests to meet their obligations for the
   payment of interest and principal when due. Although the Fund seeks to reduce
   risk by portfolio diversification, credit analysis, and attention to trends
   in the economy, industries and financial markets, such efforts will not
   eliminate all risk. There can, of course, be no assurance that the Fund will
   achieve its investment objective.    
 
   After purchase by the Fund, a debt security may cease to be rated or its
   rating may be reduced below the minimum required for purchase by the Fund.
   For the Money Funds, the procedures set forth in Rule 2a-7, under the 1940
   Act, may require the prompt sale of any such security. For the other Funds,
   neither event will require a sale of such security by the Fund. However, T.
   Rowe Price will consider such event in its determination of whether the Fund
   should continue to hold the security. To the extent that the ratings given by
   Moody's or S&P may change as a result of changes in such organizations or
   their rating systems, the Fund will attempt to use comparable ratings as
   standards for investments in accordance with the investment policies
   contained in the prospectus. When purchasing unrated securities, T. Rowe
   Price, under the supervision of the Fund's Board of Directors, determines
   whether the unrated security is of a quality comparable to that which the
   Fund is allowed to purchase.
 
   Securities backed by the full faith and credit of the United States (for
   example, GNMA and U.S. Treasury securities) are generally considered to be
   among the most, if not the most, creditworthy investments available. While
   the U.S. government has honored its credit obligations continuously for the
   last 200 years, political events in 1995 and 1996, at times, called into
   question whether the United States would default on its obligations. Such an
   event would be unprecedented and there is no way to predict its results on
   the securities markets or the Funds. However, it is very likely default by
   the U.S. would result in losses to the Funds.
 
   Mortgage Securities--All Funds except Cash Reserves Fund
   Mortgage-backed securities differ from conventional bonds in that principal
   is paid back over the life of the security rather than at maturity. As a
   result, the holder of a mortgage-backed security (i.e., the Fund) receives
   monthly scheduled payments of principal and interest, and may receive
   unscheduled principal payments representing prepayments on the underlying
   mortgages. The incidence of unscheduled principal prepayments is also likely
   to increase in mortgage pools owned by the Fund when prevailing mortgage loan
   rates fall below the mortgage rates of the securities underlying the
   individual pool. The effect of such prepayments in a falling rate environment
   is to (1) cause the Fund to reinvest principal payments at the then lower
   prevailing interest rate, and (2) reduce the potential for capital
   appreciation beyond the face amount of the security. Conversely, the Fund may
   realize a gain on prepayments of mortgage pools trading at a discount. Such
   prepayments will provide an early return of principal which may then be
   reinvested at the then higher prevailing interest rate.
 
   The market value of adjustable rate mortgage securities ("ARMs"), like other
   U.S. government securities, will generally vary inversely with changes in
   market interest rates, declining when interest rates rise and rising when
   interest rates decline. Because of their periodic adjustment feature, ARMs
   should be more sensitive to short-term interest rates than long-term rates.
   They should also display less volatility than long-term
 
 
<PAGE>
 
   mortgage-backed securities. Thus, while having less risk of a decline during
   periods of rapidly rising rates, ARMs may also have less potential for
   capital appreciation than other investments of comparable maturities.
   Interest rate caps on mortgages underlying ARM securities may prevent income
   on the ARM from increasing to prevailing interest rate levels and cause the
   securities to decline in value. In addition, to the extent ARMs are purchased
   at a premium, mortgage foreclosures and unscheduled principal prepayments may
   result in some loss of the holders' principal investment to the extent of the
   premium paid. On the other hand, if ARMs are purchased at a discount, both a
   scheduled payment of principal and an unscheduled prepayment of principal
   will increase current and total returns and will accelerate the recognition
   of income which when distributed to shareholders will be taxable as ordinary
   income.
 
   Limited-Term Bond Fund
 
   Special Risks of High-Yield Investing The Fund may invest in low-quality
   bonds commonly referred to as "junk bonds." Junk bonds are regarded as
   predominantly speculative with respect to the issuer's continuing ability to
   meet principal and interest payments. Because investment in low- and
   lower-medium-quality bonds involves greater investment risk, to the extent
   the Fund invests in such bonds, achievement of its investment objective will
   be more dependent on T. Rowe Price's credit analysis than would be the case
   if the Fund were investing in higher-quality bonds. High-yield bonds may be
   more susceptible to real or perceived adverse economic conditions than
   investment-grade bonds. A projection of an economic downturn, or higher
   interest rates, for example, could cause a decline in high-yield bond prices
   because the advent of such events could lessen the ability of highly
   leveraged issuers to make principal and interest payments on their debt
   securities. In addition, the secondary trading market for high-yield bonds
   may be less liquid than the market for higher-grade bonds, which can
   adversely affect the ability of a Fund to dispose of its portfolio
   securities. Bonds for which there is only a "thin" market can be more
   difficult to value inasmuch as objective pricing data may be less available
   and judgment may play a greater role in the valuation process.
 
 
 
 RISK FACTORS FOR SUMMIT MUNICIPAL FUNDS
 -------------------------------------------------------------------------------
   Reference is also made to the sections entitled "Types of Securities" and
   "Portfolio Management Practices" for discussions of the risks associated with
   the investments and practices described therein as they apply to the Fund.
 
 
                              Municipal Securities
 
   The Funds are designed for investors who, because of their tax bracket, can
   benefit from investment in municipal bonds whose income is exempt from
   federal taxes. The Funds are not appropriate for qualified retirement plans
   where income is already tax deferred.
 
   
   Yields on municipal securities are dependent on a variety of factors,
   including the general conditions of the money market and the municipal bond
   market, the size of a particular offering, the maturity of the obligations,
   and the rating of the issue. Municipal securities with longer maturities tend
   to produce higher yields and are generally subject to potentially greater
   capital appreciation and depreciation than obligations with shorter
   maturities and lower yields. The market prices of municipal securities
   usually vary, depending upon available yields. An increase in interest rates
   will generally reduce the value of portfolio investments, and a decline in
   interest rates will generally increase the value of portfolio investments.
   The ability of all the Funds to achieve their investment objectives is also
   dependent on the continuing ability of the issuers of municipal securities in
   which the Funds invest to meet their obligations for the payment of interest
   and principal when due. The ratings of Moody's, S&P, and Fitch IBCA, Inc.
   ("Fitch") represent their opinions as to the quality of municipal securities
   which they undertake to rate. Ratings are not absolute standards of quality;
   consequently, municipal securities with the same maturity, coupon, and rating
   may have different yields. There are variations in municipal securities, both
   within a particular classification and between classifications, depending on
   numerous factors. It should also be pointed out that, unlike other types of
    
 
 
<PAGE>
 
   
   investments, municipal securities have traditionally not been subject to
   regulation by, or registration with, the SEC, although there have been
   proposals which would provide for regulation in the future.    
 
   The federal bankruptcy statutes relating to the debts of political
   subdivisions and authorities of states of the United States provide that, in
   certain circumstances, such subdivisions or authorities may be authorized to
   initiate bankruptcy proceedings without prior notice to or consent of
   creditors, which proceedings could result in material and adverse changes in
   the rights of holders of their obligations.
 
   Proposals have been introduced in Congress to restrict or eliminate the
   federal income tax exemption for interest on municipal securities, and
   similar proposals may be introduced in the future. Proposed "Flat Tax" and
   "Value Added Tax" proposals would also have the effect of eliminating the tax
   preference for municipal securities. Some of the past proposals would have
   applied to interest on municipal securities issued before the date of
   enactment, which would have adversely affected their value to a material
   degree. If such a proposal were enacted, the availability of municipal
   securities for investment by the Funds and the value of a Fund's portfolio
   would be affected and, in such an event, a Fund would reevaluate its
   investment objectives and policies.
 
   Although the banks and securities dealers with which the Fund will transact
   business will be banks and securities dealers that T. Rowe Price believes to
   be financially sound, there can be no assurance that they will be able to
   honor their obligations to the Fund with respect to such securities.
 
   Municipal Bond Insurance All of the Funds may purchase insured bonds from
   time to time. Municipal bond insurance provides an unconditional and
   irrevocable guarantee that the insured bond's principal and interest will be
   paid when due. The guarantee is purchased from a private, non-governmental
   insurance company.
 
   There are two types of insured securities that may be purchased by the Funds:
   bonds carrying either (1) new issue insurance; or (2) secondary insurance.
   New issue insurance is purchased by the issuer of a bond in order to improve
   -------------------
   the bond's credit rating. By meeting the insurer's standards and paying an
   insurance premium based on the bond's principal value, the issuer is able to
   obtain a higher credit rating for the bond. Once purchased, municipal bond
   insurance cannot be canceled, and the protection it affords continues as long
   as the bonds are outstanding and the insurer remains solvent.
 
   The Funds may also purchase bonds that carry secondary insurance purchased by
                                                -------------------
   an investor after a bond's original issuance. Such policies insure a security
   for the remainder of its term. Generally, the Funds expect that portfolio
   bonds carrying secondary insurance will have been insured by a prior
   investor. However, the Funds may, on occasion, purchase secondary insurance
   on their own behalf.
 
   Each of the municipal bond insurance companies has established reserves to
   cover estimated losses. Both the method of establishing these reserves and
   the amount of the reserves vary from company to company. The risk that a
   municipal bond insurance company may experience a claim extends over the life
   of each insured bond. Municipal bond insurance companies are obligated to pay
   a bond's interest and principal when due if the issuing entity defaults on
   the insured bond. Although defaults on insured municipal bonds have been low
   to date, there is no assurance this low rate will continue in the future. A
   higher than expected default rate could deplete loss reserves and adversely
   affect the ability of a municipal bond insurer to pay claims to holders of
   insured bonds, such as the Fund.
 
   Municipal Money Market Fund
 
   
   The Money Fund will limit its purchases of portfolio instruments to those
   U.S. dollar-denominated securities which the Fund's Board of Directors
   determines present minimal credit risk, and which are Eligible Securities as
   defined in Rule 2a-7 under the 1940 Act. Eligible Securities are generally
   securities which have been rated (or whose issuer has been rated or whose
   issuer has comparable securities rated) in one of the two highest short-term
   rating categories (which may include sub-categories) by nationally recognized
   statistical rating organizations or, in the case of any instrument that is
   not so rated, is of comparable high quality as determined by T. Rowe Price
   pursuant to written guidelines established under the supervision of the
   Fund's Board of Directors. In addition, the Fund may treat variable and
   floating rate instruments with demand features as short-term securities
   pursuant to Rule 2a-7 under the 1940 Act.    
 
 
<PAGE>
 
   There can be no assurance that the Fund will achieve its investment
   objectives or be able to maintain its net asset value per share at $1.00. The
   price of the Fund is not guaranteed or insured, and its yield is not fixed.
   While the Fund invests in high-grade money market instruments, investment in
   the Fund is not without risk even if all portfolio instruments are paid in
   full at maturity. An increase in interest rates could reduce the value of the
   Fund's portfolio investments, and a decline in interest rates could increase
   the value.
 
   The price stability and liquidity of the Money Fund may not be equal to that
   of a taxable money market fund which exclusively invests in short-term
   taxable money market securities. The taxable money market is a broader and
   more liquid market with a greater number of investors, issuers, and market
   makers than the short-term municipal securities market. The weighted average
   maturity of the fund varies: the shorter the average maturity of a portfolio,
   the less its price will be impacted by interest rate fluctuations.
 
   Intermediate and Income Funds
 
   Because of their investment policies, the Intermediate and Income Funds may
   not be suitable or appropriate for all investors. The Funds are designed for
   investors who wish to invest in long-term funds for income, and who would
   benefit, because of their tax bracket, from receiving income that is exempt
   from federal income taxes. The Intermediate and Income Funds' investment
   programs permit the purchase of investment-grade securities that do not meet
   the high-quality standards of the Money Funds. Since investors generally
   perceive that there are greater risks associated with investment in
   lower-quality securities, the yield from such securities normally exceeds
   those obtainable from higher-quality securities. In addition, the principal
   value of long term lower-rated securities generally will fluctuate more
   widely than higher-quality securities. Lower-quality investments entail a
   higher risk of default--that is, the nonpayment of interest and principal by
   the issuer than higher-quality investments. The value of the portfolio
   securities of the Intermediate and Income Funds will fluctuate based upon
   market conditions. Although these Funds seek to reduce credit risk by
   investing in a diversified portfolio, such diversification does not eliminate
   all risk. These Funds are also not intended to provide a vehicle for
   short-term trading purposes.
 
 
                                Debt Obligations
 
   
   Yields on short-, intermediate-, and long-term debt securities are dependent
   on a variety of factors, including the general conditions of the money and
   bond markets, the size of a particular offering, the maturity of the
   obligation, and the credit quality and rating of the issue. Debt securities
   with longer maturities tend to have higher yields and are generally subject
   to potentially greater capital appreciation and depreciation than obligations
   with shorter maturities and lower yields. The market prices of debt
   securities usually vary, depending upon available yields. An increase in
   interest rates will generally reduce the value of portfolio debt securities,
   and a decline in interest rates will generally increase the value of
   portfolio debt securities. The ability of the Fund to achieve its investment
   objective is also dependent on the continuing ability of the issuers of the
   debt securities in which the Fund invests to meet their obligations for the
   payment of interest and principal when due. Although the Fund seeks to reduce
   risk by portfolio diversification, credit analysis, and attention to trends
   in the economy, industries and financial markets, such efforts will not
   eliminate all risk. There can, of course, be no assurance that the Fund will
   achieve its investment objective.    
 
   After purchase by the Fund, a debt security may cease to be rated or its
   rating may be reduced below the minimum required for purchase by the Fund.
   For the Money Funds, the procedures set forth in Rule 2a-7, under the 1940
   Act, may require the prompt sale of any such security. For the other Funds,
   neither event will require a sale of such security by the Fund. However, T.
   Rowe Price will consider such event in its determination of whether the Fund
   should continue to hold the security. To the extent that the ratings given by
   Moody's or S&P may change as a result of changes in such organizations or
   their rating systems, the Fund will attempt to use comparable ratings as
   standards for investments in accordance with the investment policies
   contained in the prospectus. When purchasing unrated securities, T. Rowe
   Price, under the supervision of the Fund's Board of Directors, determines
   whether the unrated security is of a quality comparable to that which the
   Fund is allowed to purchase.
 
   Special Risks of High-Yield Investing The Fund may invest in low-quality
   bonds commonly referred to as "junk bonds." Junk bonds are regarded as
   predominantly speculative with respect to the issuer's continuing
 
 
<PAGE>
 
   ability to meet principal and interest payments. Because investment in low-
   and lower-medium-quality bonds involves greater investment risk, to the
   extent the Fund invests in such bonds, achievement of its investment
   objective will be more dependent on T. Rowe Price's credit analysis than
   would be the case if the Fund were investing in higher-quality bonds.
   High-yield bonds may be more susceptible to real or perceived adverse
   economic conditions than investment-grade bonds. A projection of an economic
   downturn, or higher interest rates, for example, could cause a decline in
   high-yield bond prices because the advent of such events could lessen the
   ability of highly leveraged issuers to make principal and interest payments
   on their debt securities. In addition, the secondary trading market for
   high-yield bonds may be less liquid than the market for higher-grade bonds,
   which can adversely affect the ability of a Fund to dispose of its portfolio
   securities. Bonds for which there is only a "thin" market can be more
   difficult to value inasmuch as objective pricing data may be less available
   and judgment may play a greater role in the valuation process.
 
 
 
 INVESTMENT PROGRAM
 -------------------------------------------------------------------------------
   All Summit Income Funds
 
 
                               Types of Securities
 
   Set forth below is additional information about certain of the investments
   described in the Fund's prospectus.
 
 
                           Adjustable Rate Securities
 
   Generally, the maturity of a security is deemed to be the period remaining
   until the date (noted on the face of the instrument) on which the principal
   amount must be paid, or in the case of an instrument called for redemption,
   the date on which the redemption payment must be made. However, certain
   securities may be issued with adjustable interest rates that are reset
   periodically by predetermined formulas or indexes in order to minimize
   movements in the principal value of the investment. In accordance with Rule
   2a-7 under the 1940 Act. Such securities may have long-term maturities, but
   may be treated as a short-term investment under certain conditions.
   Generally, as interest rates decrease or increase, the potential for capital
   appreciation or depreciation on these securities is less than for fixed rate
   obligations. These securities may take the following forms:
 
  . Variable Rate Securities A variable rate instrument is one whose terms
   provide for the adjustment of its interest rate on set dates and which, upon
   each adjustment until the final maturity of the instrument or the period
   remaining until the principal amount can be recovered through demand, can
   reasonably be expected to have a market value which approximates its
   amortized cost. A variable rate instrument, the principal amount of which is
   scheduled to be paid in 397 calendar days or less, is deemed to have a
   maturity equal to the earlier of the period remaining until the next
   readjustment of the interest rate or the period remaining until the principal
   amount can be recovered through demand. A variable rate instrument the
   principal amount of which is scheduled to be paid in more than 397 calendar
   days and which is subject to a demand feature which entitles the purchaser to
   receive the principal amount of the underlying security or securities, either
   (i) at any time upon notice of no more than 30 days, or (ii) at specified
   intervals not exceeding 397 calendar days and upon no more than 30 days'
   notice ("Demand Feature"), is deemed to have a maturity equal to the longer
   of the period remaining until the next readjustment of the interest rate or
   the period remaining until the principal amount can be recovered through
   demand. A government security that is a variable rate security where the
   variable rate is readjusted no less frequently than every 762 calendar days
   is deemed to have a maturity equal to the period remaining until the next
   readjustment of the interest rate.
 
  . Floating Rate Securities A floating rate security provides for the
   adjustment of its interest rates whenever a specified interest rate changes
   and which, at any time until the final maturity of the instrument or the
   period remaining until the principal amount can be recovered through demand,
   can reasonably be expected to have a market value that approximates its
   amortized cost. A floating rate security, the principal amount of which must
   unconditionally be paid in 397 calendar days or less is deemed to have a
   maturity of one day. A floating rate security, the principal amount of which
   is scheduled to be paid in more than 397 calendar days, that is
 
 
<PAGE>
 
   subject to a Demand Feature is deemed to have a maturity equal to the period
   remaining until the principal amount can be recovered through demand. A
   government security that is a floating rate security is deemed to have a
   remaining maturity of one day.
 
  . Put Option Bonds Long-term obligations with maturities longer than one year
   may provide purchasers an optional or mandatory tender of the security at par
   value at predetermined intervals, often ranging from one month to several
   years (e.g., a 30-year bond with a five-year tender period). These
   instruments are deemed to have a maturity equal to the period remaining to
   the put date.
 
 
             When-Issued Securities and Forward Commitment Contracts
 
   The price of such securities, which may be expressed in yield terms, is fixed
   at the time the commitment to purchase is made, but delivery and payment take
   place at a later date. Normally, the settlement date occurs within 90 days of
   the purchase for When-Issueds, but may be substantially longer for Forwards.
   During the period between purchase and settlement, no payment is made by the
   Fund to the issuer and no interest accrues to the Fund. The purchase of these
   securities will result in a loss if their value declines prior to the
   settlement date. This could occur, for example, if interest rates increase
   prior to settlement. The longer the period between purchase and settlement,
   the greater the risks are. At the time the Fund makes the commitment to
   purchase these securities, it will record the transaction and reflect the
   value of the security in determining its net asset value. The Fund will cover
   these securities by maintaining cash, liquid, high-grade debt securities, or
   other suitable cover as permitted by the SEC with its custodian bank equal in
   value to commitments for them during the time between the purchase and the
   settlement. Therefore, the longer this period, the longer the period during
   which alternative investment options are not available to the Fund (to the
   extent of the securities used for cover). Such securities either will mature
   or, if necessary, be sold on or before the settlement date.
 
   To the extent the Fund remains fully or almost fully invested (in securities
   with a remaining maturity of more than one year) at the same time it
   purchases these securities, there will be greater fluctuations in the Fund's
   net asset value than if the Fund did not purchase them.
 
 
                             Money Market Securities
 
   The money market securities that the Funds may invest in are generally
   limited to those described below.
 
  . U.S. Government Obligations Bills, notes, bonds, and other debt securities
   issued by the U.S. Treasury. These are direct obligations of the U.S.
   government and differ mainly in the length of their maturities.
 
  . U.S. Government Agency Securities Issued or guaranteed by U.S.
   government-sponsored enterprises and federal agencies. These include
   securities issued by the Federal National Mortgage Association, Government
   National Mortgage Association, Federal Home Loan Bank, Federal Land Banks,
   Farmers Home Administration, Banks for Cooperatives, Federal Intermediate
   Credit Banks, Federal Financing Bank, Farm Credit Banks, the Small Business
   Association, and the Tennessee Valley Authority. Some of these securities are
   supported by the full faith and credit of the U.S. Treasury; the remainder
   are supported only by the credit of the instrumentality, which may or may not
   include the right of the issuer to borrow from the Treasury.
 
  . Bank Obligations Certificates of deposit, bankers' acceptances, and other
   short-term debt obligations. Certificates of deposit are short-term
   obligations of commercial banks. A bankers' acceptance is a time draft drawn
   on a commercial bank by a borrower, usually in connection with international
   commercial transactions. Certificates of deposit may have fixed or variable
   rates. The Fund may invest in U.S. banks, foreign branches of U.S. banks,
   U.S. branches of foreign banks, and foreign branches of foreign banks.
 
  . Short-Term Corporate Debt Securities Outstanding nonconvertible corporate
   debt securities (e.g., bonds and debentures) which have one year or less
   remaining to maturity. Corporate notes may have fixed, variable, or floating
   rates.
 
  . Commercial Paper Short-term promissory notes issued by corporations
   primarily to finance short-term credit needs. Certain notes may have floating
   or variable rates.
 
 
<PAGE>
 
  . Foreign Government Securities Issued or guaranteed by a foreign government,
   province, instrumentality, political subdivision, or similar unit thereof.
   However, the Cash Reserves Fund will only purchase these securities if they
   are payable in U.S. dollars.
 
  . Savings and Loan Obligations Negotiable certificates of deposit and other
   short-term debt obligations of savings and loan associations.
 
  . Supranational Agencies Securities of certain supranational entities, such as
   the International Development Bank.
 
  . Determination of Maturity of Money Market Securities The Money Fund may only
   purchase securities which at the time of investment have remaining maturities
   of 397 calendar days or less. The other Funds may also purchase money market
   securities. In determining the maturity of money market securities, Funds
   will follow the provisions of Rule 2a-7 under the 1940 Act.
 
  . First Tier Money Market Securities Defined At least 95% of the Cash Reserves
   Fund's total assets will be maintained in first tier money market securities.
   First tier money market securities are those which are described as First
   Tier Securities under Rule 2a-7 of the 1940 Act. These include any security
   with a remaining maturity of 397 days or less that is rated (or that has been
   issued by an issuer that is rated with respect to a class of short-term debt
   obligations, or any security within that class that is comparable in priority
   and security with the security) by any two nationally recognized statistical
   rating organizations (NRSROs) (or if only one NRSRO has issued a rating, that
   NRSRO) in the highest rating category for short-term debt obligations (within
   which there may be sub-categories). First Tier Securities also include
   unrated securities comparable in quality to rated securities, as determined
   by T. Rowe Price pursuant to written guidelines established in accordance
   with Rule 2a-7 under the 1940 Act under the supervision of the Fund's Board
   of Directors.
 
 
                             Asset-Backed Securities
 
   Each fund may invest a portion of its assets in debt obligations known as
   asset-backed securities.
 
   The credit quality of most asset-backed securities depends primarily on the
   credit quality of the assets underlying such securities, how well the entity
   issuing the security is insulated from the credit risk of the originator or
   any other affiliated entities and the amount and quality of any credit
   support provided to the securities. The rate of principal payment on
   asset-backed securities generally depends on the rate of principal payments
   received on the underlying assets which in turn may be affected by a variety
   of economic and other factors. As a result, the yield on any asset-backed
   security is difficult to predict with precision and actual yield to maturity
   may be more or less than the anticipated yield to maturity. Asset-backed
   securities may be classified as pass-through certificates or collateralized
   obligations.
 
   Pass-through certificates are asset-backed securities which represent an
   undivided fractional ownership interest in an underlying pool of assets.
   Pass-through certificates usually provide for payments of principal and
   interest received to be passed through to their holders, usually after
   deduction for certain costs and expenses incurred in administering the pool.
 
   Because pass-through certificates represent an ownership interest in the
   underlying assets, the holders thereof bear directly the risk of any defaults
   by the obligors on the underlying assets not covered by any credit support.
   See "Types of Credit Support."
 
   Asset-backed securities issued in the form of debt instruments, also known as
   collateralized obligations, are generally issued as the debt of a special
   purpose entity organized solely for the purpose of owning such assets and
   issuing such debt. Such assets are most often trade, credit card or
   automobile receivables. The assets collateralizing such asset-backed
   securities are pledged to a trustee or custodian for the benefit of the
   holders thereof. Such issuers generally hold no assets other than those
   underlying the asset-backed securities and any credit support provided. As a
   result, although payments on such asset-backed securities are obligations of
   the issuers, in the event of defaults on the underlying assets not covered by
   any credit support (see "Types of
 
 
<PAGE>
 
   Credit Support"), the issuing entities are unlikely to have sufficient assets
   to satisfy their obligations on the related asset-backed securities.
 
  . Methods of Allocating Cash Flows While many asset-backed securities are
   issued with only one class of security, many asset-backed securities are
   issued in more than one class, each with different payment terms. Multiple
   class asset-backed securities are issued for two main reasons. First,
   multiple classes may be used as a method of providing credit support. This is
   accomplished typically through creation of one or more classes whose right to
   payments on the asset-backed security is made subordinate to the right to
   such payments of the remaining class or classes. See "Types of Credit
   Support." Second, multiple classes may permit the issuance of securities with
   payment terms, interest rates or other characteristics differing both from
   those of each other and from those of the underlying assets. Examples include
   so-called "strips" (asset-backed securities entitling the holder to
   disproportionate interests with respect to the allocation of interest and
   principal of the assets backing the security), and securities with class or
   classes having characteristics which mimic the characteristics of
   non-asset-backed securities, such as floating interest rates (i.e., interest
   rates which adjust as a specified benchmark changes) or scheduled
   amortization of principal.
 
   Asset-backed securities in which the payment streams on the underlying assets
   are allocated in a manner different than those described above may be issued
   in the future. The Fund may invest in such asset-backed securities if such
   investment is otherwise consistent with its investment objectives and
   policies and with the investment restrictions of the Fund.
 
  . Types of Credit Support Asset-backed securities are often backed by a pool
   of assets representing the obligations of a number of different parties. To
   lessen the effect of failures by obligors on underlying assets to make
   payments, such securities may contain elements of credit support. Such credit
   support falls into two classes: liquidity protection and protection against
   ultimate default by an obligor on the underlying assets. Liquidity protection
   refers to the provision of advances, generally by the entity administering
   the pool of assets, to ensure that scheduled payments on the underlying pool
   are made in a timely fashion. Protection against ultimate default ensures
   ultimate payment of the obligations on at least a portion of the assets in
   the pool. Such protection may be provided through guarantees, insurance
   policies or letters of credit obtained from third parties "external credit
   enhancement", through various means of structuring the transaction "internal
   credit enhancement" or through a combination of such approaches. Examples of
   asset-backed securities with credit support arising out of the structure of
   the transaction include "senior-subordinated securities" (multiple class
   asset-backed securities with certain classes subordinate to other classes as
   to the payment of principal thereon, with the result that defaults on the
   underlying assets are borne first by the holders of the subordinated class)
   and asset-backed securities that have "reserve funds" (where cash or
   investments, sometimes funded from a portion of the initial payments on the
   underlying assets, are held in reserve against future losses) or that have
   been "over collateralized" (where the scheduled payments on, or the principal
   amount of, the underlying assets substantially exceeds that required to make
   payment of the asset-backed securities and pay any servicing or other fees).
   The degree of credit support provided on each issue is based generally on
   historical information respecting the level of credit risk associated with
   such payments. Depending upon the type of assets securitized, historical
   information on credit risk and prepayment rates may be limited or even
   unavailable. Delinquency or loss in excess of that anticipated could
   adversely affect the return on an investment in an asset-backed security.
 
  . Automobile Receivable Securities The Fund may invest in asset-backed
   securities which are backed by receivables from motor vehicle installment
   sales contracts or installment loans secured by motor vehicles ("Automobile
   Receivable Securities"). Since installment sales contracts for motor vehicles
   or installment loans related thereto ("Automobile Contracts") typically have
   shorter durations and lower incidences of prepayment, Automobile Receivable
   Securities generally will exhibit a shorter average life and are less
   susceptible to prepayment risk.
 
   Most entities that issue Automobile Receivable Securities create an
   enforceable interest in their respective Automobile Contracts only by filing
   a financing statement and by having the servicer of the Automobile Contracts,
   which is usually the originator of the Automobile Contracts, take custody
   thereof. In such circumstances, if the servicer of the Automobile Contracts
   were to sell the same Automobile Contracts to
 
 
<PAGE>
 
   another party, in violation of its obligation not to do so, there is a risk
   that such party could acquire an interest in the Automobile Contracts
   superior to that of the holders of Automobile Receivable Securities. Also,
   although most Automobile Contracts grant a security interest in the motor
   vehicle being financed, in most states the security interest in a motor
   vehicle must be noted on the certificate of title to create an enforceable
   security interest against competing claims of other parties. Due to the large
   number of vehicles involved, however, the certificate of title to each
   vehicle financed, pursuant to the Automobile Contracts underlying the
   Automobile Receivable Security, usually is not amended to reflect the
   assignment of the seller's security interest for the benefit of the holders
   of the Automobile Receivable Securities. Therefore, there is the possibility
   that recoveries on repossessed collateral may not, in some cases, be
   available to support payments on the securities. In addition, various state
   and federal securities laws give the motor vehicle owner the right to assert
   against the holder of the owner's Automobile Contract certain defenses such
   owner would have against the seller of the motor vehicle. The assertion of
   such defenses could reduce payments on the Automobile Receivable Securities.
 
  . Credit Card Receivable Securities The Fund may invest in asset-backed
   securities backed by receivables from revolving credit card agreements
   ("Credit Card Receivable Securities"). Credit balances on revolving credit
   card agreements ("Accounts") are generally paid down more rapidly than are
   Automobile Contracts. Most of the Credit Card Receivable Securities issued
   publicly to date have been Pass-Through Certificates. In order to lengthen
   the maturity of Credit Card Receivable Securities, most such securities
   provide for a fixed period during which only interest payments on the
   underlying Accounts are passed through to the security holder and principal
   payments received on such Accounts are used to fund the transfer to the pool
   of assets supporting the related Credit Card Receivable Securities of
   additional credit card charges made on an Account. The initial fixed period
   usually may be shortened upon the occurrence of specified events which signal
   a potential deterioration in the quality of the assets backing the security,
   such as the imposition of a cap on interest rates. The ability of the issuer
   to extend the life of an issue of Credit Card Receivable Securities thus
   depends upon the continued generation of additional principal amounts in the
   underlying account during the initial period and the non-occurrence of
   specified events. An acceleration in cardholders' payment rates or any other
   event which shortens the period during which additional credit card charges
   on an Account may be transferred to the pool of assets supporting the related
   Credit Card Receivable Security could shorten the weighted average life and
   yield of the Credit Card Receivable Security.
 
   Credit cardholders are entitled to the protection of a number of state and
   federal consumer credit laws, many of which give such holder the right to set
   off certain amounts against balances owed on the credit card, thereby
   reducing amounts paid on Accounts. In addition, unlike most other
   asset-backed securities, Accounts are unsecured obligations of the
   cardholder.
 
  . Other Assets Asset-backed securities backed by assets other than those
   described above, including, but not limited to, small-business loans and
   accounts receivable, equipment leases, commercial real estate loans, boat
   loans and manufacturing housing loans. The Fund may invest in such securities
   in the future if such investment is otherwise consistent with its investment
   objective and policies.
 
   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.
 
 
                        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% (10% for Cash Reserves) of the value
 
 
<PAGE>
 
   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, 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% (10% for Cash Reserves) 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 will consider the trading markets for the
   specific security taking into account the unregistered nature of a Rule 144A
   security. In addition, T. Rowe Price could consider the following: (1)
   frequency of trades and quotes; (2) number of dealers and potential
   purchases; (3) dealer undertakings to make a market; and (4) the 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% (10% for Cash Reserves) 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.    
 
   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.
 
 
                           Mortgage-Related Securities
 
   Limited-Term Bond and GNMA Funds
 
   Mortgage-related securities in which the Fund may invest include, but are not
   limited to, those described below.
 
  . Mortgage-Backed Securities Mortgage-backed securities are securities
   representing an interest in a pool of mortgages. The mortgages may be of a
   variety of types, including adjustable rate, conventional 30-year fixed rate,
   graduated payment, and 15-year. Principal and interest payments made on the
   mortgages in the underlying mortgage pool are passed through to the Fund.
   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.
 
  . U.S. Government Agency Mortgage-Backed Securities These are obligations
   issued or guaranteed by the United States government or one of its agencies
   or instrumentalities, such as the Government National Mortgage Association
   ("Ginnie Mae" or "GNMA"), the Federal National Mortgage Association ("Fannie
   Mae" or "FNMA") the Federal Home Loan Mortgage Corporation ("Freddie Mac" or
   "FHLMC"), and the Federal Agricultural Mortgage Corporation ("Farmer Mac" or
   "FAMC"). FNMA, FHLMC, and FAMC obligations are not backed by the full faith
   and credit of the U.S. government as GNMA certificates are, but they are
   supported by the instrumentality's right to borrow from the United States
   Treasury. U.S. Government Agency Mortgage-Backed Certificates provide for the
   pass-through to investors of their pro-rata share of monthly payments
   (including any prepayments) made by the individual borrowers on the pooled
   mortgage loans, net of any fees paid to the guarantor of such securities and
   the servicer of the underlying mortgage loans. Each of GNMA, FNMA, FHLMC, and
   FAMC guarantees timely distributions of interest to certificate holders. GNMA
   and FNMA guarantee timely distributions of scheduled principal. FHLMC has in
   the past
 
 
<PAGE>
 
   guaranteed only the ultimate collection of principal of the underlying
   mortgage loan; however, FHLMC now issues mortgage-backed securities (FHLMC
   Gold PCS) which also guarantee timely payment of monthly principal
   reductions.
 
  . Ginnie Mae Certificates Ginnie Mae is a wholly owned corporate
   instrumentality of the United States within the Department of Housing and
   Urban Development. The National Housing Act of 1934, as amended (the "Housing
   Act"), authorizes Ginnie Mae to guarantee the timely payment of the principal
   of and interest on certificates that are based on and backed by a pool of
   mortgage loans insured by the Federal Housing Administration under the
   Housing Act, or Title V of the Housing Act of 1949 ("FHA Loans"), or
   guaranteed by the Department of Veterans Affairs under the Servicemen's
   Readjustment Act of 1944, as amended ("VA Loans"), or by pools of other
   eligible mortgage loans. The Housing Act provides that the full faith and
   credit of the United States government is pledged to the payment of all
   amounts that may be required to be paid under any guaranty. In order to meet
   its obligations under such guaranty, Ginnie Mae is authorized to borrow from
   the United States Treasury with no limitations as to amount.
 
  . Fannie Mae Certificates Fannie Mae is a federally chartered and privately
   owned corporation organized and existing under the Federal National Mortgage
   Association Charter Act of 1938. FNMA Certificates represent a pro-rata
   interest in a group of mortgage loans purchased by Fannie Mae. FNMA
   guarantees the timely payment of principal and interest on the securities it
   issues. The obligations of FNMA are not backed by the full faith and credit
   of the U.S. government.
 
  . Freddie Mac Certificates Freddie Mac is a corporate instrumentality of the
   United States created pursuant to the Emergency Home Finance Act of 1970, as
   amended (the "FHLMC Act"). Freddie Mac Certificates represent a pro-rata
   interest in a group of mortgage loans (a "Freddie Mac Certificate") purchased
   by Freddie Mac. Freddie Mac guarantees timely payment of interest and
   principal on certain securities it issues and timely payment of interest and
   eventual payment of principal on other securities it issues. The obligations
   of Freddie Mac are obligations solely of Freddie Mac and are not backed by
   the full faith and credit of the U.S. government.
 
  . Farmer Mac Certificates Farmer Mac is a federally chartered instrumentality
   of the United States established by Title VIII of the Farm Credit Act of
   1971, as amended ("Charter Act"). Farmer Mac was chartered primarily to
   attract new capital for financing of agricultural real estate by making a
   secondary market in certain qualified agricultural real estate loans. Farmer
   Mac provides guarantees of timely payment of principal and interest on
   securities representing interests in, or obligations backed by, pools of
   mortgages secured by first liens on agricultural real estate ("Farmer Mac
   Certificates"). Similar to Fannie Mae and Freddie Mac, Farmer Mac
   Certificates are not supported by the full faith and credit of the U.S.
   government; rather, Farmer Mac may borrow from the U.S. Treasury to meet its
   guaranty obligations.
 
   As discussed above, prepayments on the underlying mortgages and their effect
   upon the rate of return of a mortgage-backed security, is the principal
   investment risk for a purchaser of such securities, like the Fund. Over time,
   any pool of mortgages will experience prepayments due to a variety of
   factors, including (1) sales of the underlying homes (including
   foreclosures), (2) refinancings of the underlying mortgages, and (3)
   increased amortization by the mortgagee. These factors, in turn, depend upon
   general economic factors, such as level of interest rates and economic
   growth. Thus, investors normally expect prepayment rates to increase during
   periods of strong economic growth or declining interest rates, and to
   decrease in recessions and rising interest rate environments. Accordingly,
   the life of the mortgage-backed security is likely to be substantially
   shorter than the stated maturity of the mortgages in the underlying pool.
   Because of such variation in prepayment rates, it is not possible to predict
   the life of a particular mortgage-backed security, but FHA statistics
   indicate that 25- to 30-year single family dwelling mortgages have an average
   life of approximately 12 years. The majority of Ginnie Mae Certificates are
   backed by mortgages of this type, and, accordingly, the generally accepted
   practice treats Ginnie Mae Certificates as 30-year securities which prepay in
   full in the 12th year. FNMA and Freddie Mac Certificates may have differing
   prepayment characteristics.
 
 
<PAGE>
 
   Fixed rate mortgage-backed securities bear a stated "coupon rate" which
   represents the effective mortgage rate at the time of issuance, less certain
   fees to GNMA, FNMA and FHLMC for providing the guarantee, and the issuer for
   assembling the pool and for passing through monthly payments of interest and
   principal.
 
   Payments to holders of mortgage-backed securities consist of the monthly
   distributions of interest and principal less the applicable fees. The actual
   yield to be earned by a holder of mortgage-backed securities is calculated by
   dividing interest payments by the purchase price paid for the mortgage-backed
   securities (which may be at a premium or a discount from the face value of
   the certificate).
 
   Monthly distributions of interest, as contrasted to semiannual distributions
   which are common for other fixed interest investments, have the effect of
   compounding and thereby raising the effective annual yield earned on
   mortgage-backed securities. Because of the variation in the life of the pools
   of mortgages which back various mortgage-backed securities, and because it is
   impossible to anticipate the rate of interest at which future principal
   payments may be reinvested, the actual yield earned from a portfolio of
   mortgage-backed securities will differ significantly from the yield estimated
   by using an assumption of a certain life for each mortgage-backed security
   included in such a portfolio as described above.
 
  . Collateralized Mortgage Obligations (CMOs) CMOs are bonds that are
   collateralized by whole loan mortgages or mortgage pass-through securities.
   The bonds issued in a CMO deal are divided into groups, and each group of
   bonds is referred to as a "tranche." Under the traditional CMO structure, the
   cash flows generated by the mortgages or mortgage pass-through securities in
   the collateral pool are used to first pay interest and then pay principal to
   the CMO bondholders. The bonds issued under a CMO structure are retired
   sequentially as opposed to the pro-rata return of principal found in
   traditional pass-through obligations. Subject to the various provisions of
   individual CMO issues, the cash flow generated by the underlying collateral
   (to the extent it exceeds the amount required to pay the stated interest) is
   used to retire the bonds. Under the CMO structure, the repayment of principal
   among the different tranches is prioritized in accordance with the terms of
   the particular CMO issuance. The "fastest-pay" tranche of bonds, as specified
   in the prospectus for the issuance, would initially receive all principal
   payments. When that tranche of bonds is retired, the next tranche, or
   tranches, in the sequence, as specified in the prospectus, receive all of the
   principal payments until they are retired. The sequential retirement of bond
   groups continues until the last tranche, or group of bonds, is retired.
   Accordingly, the CMO structure allows the issuer to use cash flows of long
   maturity, monthly-pay collateral to formulate securities with short,
   intermediate and long final maturities and expected average lives.
 
   In recent years, new types of CMO structures have evolved. These include
   floating rate CMOs, planned amortization classes, accrual bonds and CMO
   residuals. These newer structures affect the amount and timing of principal
   and interest received by each tranche from the underlying collateral. Under
   certain of these new structures, given classes of CMOs have priority over
   others with respect to the receipt of prepayments on the mortgages.
   Therefore, depending on the type of CMOs in which the Fund invests, the
   investment may be subject to a greater or lesser risk of prepayment than
   other types of mortgage-related securities.
 
   The primary risk of any mortgage security is the uncertainty of the timing of
   cash flows. For CMOs, the primary risk results from the rate of prepayments
   on the underlying mortgages serving as collateral. An increase or decrease in
   prepayment rates (resulting from a decrease or increase in mortgage interest
   rates) will affect the yield, average life and price of CMOs. The prices of
   certain CMOs, depending on their structure and the rate of prepayments, can
   be volatile. Some CMOs may also not be as liquid as other securities.
 
  . U.S. Government Agency Multiclass Pass-Through Securities Unlike CMOs, U.S.
   Government Agency Multiclass Pass-Through Securities, which include FNMA
   Guaranteed REMIC Pass-Through Certificates and FHLMC Multi-Class Mortgage
   Participation Certificates, are ownership interests in a pool of Mortgage
   Assets. Unless the context indicates otherwise, all references herein to CMOs
   include multiclass pass-through securities.
 
  . Multi-Class Residential Mortgage Securities Such securities represent
   interests in pools of mortgage loans to residential home buyers made by
   commercial banks, savings and loan associations or other financial
   institutions. Unlike GNMA, FNMA and FHLMC securities, the payment of
   principal and interest on Multi--
 
 
<PAGE>
 
   Class Residential Mortgage Securities is not guaranteed by the U.S.
   government or any of its agencies. Accordingly, yields on Multi-Class
   Residential Mortgage Securities have been historically higher than the yields
   on U.S. government mortgage securities. However, the risk of loss due to
   default on such instruments is higher since they are not guaranteed by the
   U.S. government or its agencies. Additionally, pools of such securities may
   be divided into senior or subordinated segments. Although subordinated
   mortgage securities may have a higher yield than senior mortgage securities,
   the risk of loss of principal is greater because losses on the underlying
   mortgage loans must be borne by persons holding subordinated securities
   before those holding senior mortgage securities.
 
  . Privately Issued Mortgage-Backed Certificates These are pass-through
   certificates issued by non-governmental issuers. Pools of conventional
   residential mortgage loans created by such issuers generally offer a higher
   rate of interest than government and government-related pools because there
   are no direct or indirect government guarantees of payment. Timely payment of
   interest and principal of these pools is, however, generally supported by
   various forms of insurance or guarantees, including individual loan, title,
   pool and hazard insurance. The insurance and guarantees are issued by
   government entities, private insurance or the mortgage poolers. Such
   insurance and guarantees and the creditworthiness of the issuers thereof will
   be considered in determining whether a mortgage-related security meets the
   Fund's quality standards. The Fund may buy mortgage-related securities
   without insurance or guarantees if through an examination of the loan
   experience and practices of the poolers, the investment manager determines
   that the securities meet the Fund's quality standards.
 
   
  . Stripped Mortgage-Backed Securities These instruments are a type of
   potentially high-risk derivative. They represent interests in a pool of
   mortgages, the cash flow of which has been separated into its interest and
   principal components. "IOs" (interest only securities) receive the interest
   portion of the cash flow while "POs" (principal only securities) receive the
   principal portion. IOs and POs are usually structured as tranches of a CMO.
   Stripped Mortgage-Backed Securities may be issued by U.S. government agencies
   or by private issuers similar to those described above with respect to CMOs
   and privately issued mortgage-backed certificates. As interest rates rise and
   fall, the value of IOs tends to move in the same direction as interest rates.
   The value of the other mortgage-backed securities described herein, like
   other debt instruments, will tend to move in the opposite direction compared
   to interest rates. Under the Code, POs may generate taxable income from the
   current accrual of original issue discount, without a corresponding
   distribution of cash to the Fund.    
 
   The cash flows and yields on IO and PO classes are extremely sensitive to the
   rate of principal payments (including prepayments) on the related underlying
   mortgage assets. In the case of IOs, prepayments affect the amount, but not
   the timing, of cash flows provided to the investor. In contrast, prepayments
   on the mortgage pool affect the timing, but not the amount, of cash flows
   received by investors in POs. For example, a rapid or slow rate of principal
   payments may have a material adverse effect on the prices of IOs or POs,
   respectively. If the underlying mortgage assets experience greater than
   anticipated prepayments of principal, an investor may fail to fully recoup
   its initial investment in an IO class of a stripped mortgage-backed security,
   even if the IO class is rated AAA or Aaa or is derived from a full faith and
   credit obligation. Conversely, if the underlying mortgage assets experience
   slower than anticipated prepayments of principal, the price on a PO class
   will be affected more severely than would be the case with a traditional
   mortgage-backed security.
 
   The staff of the SEC has advised the Fund that it believes the Fund should
   treat IOs and POs, other than government-issued IOs or POs backed by fixed
   rate mortgages, as illiquid securities and, accordingly, limit its
   investments in such securities, together with all other illiquid securities,
   to 15% of the Fund's net assets. Under the staff's position, the
   determination of whether a particular government-issued IO and PO backed by
   fixed rate mortgages may be made on a case by case basis under guidelines and
   standards established by the Fund's Board of Directors. The Fund's Board of
   Directors has delegated to T. Rowe Price the authority to determine the
   liquidity of these investments based on the following guidelines: the type of
   issuer; type of collateral, including age and prepayment characteristics;
   rate of interest on coupon relative to current market rates and the effect of
   the rate on the potential for prepayments; complexity of the issue's
   structure, including the number of tranches; size of the issue and the number
   of dealers who make a market in the IO or PO. The
 
 
<PAGE>
 
   Fund will treat nongovernment-issued IOs and POs not backed by fixed or
   adjustable rate mortgages as illiquid unless and until the SEC staff modifies
   its position.
 
  . Adjustable Rate Mortgage Securities ARMs, like fixed rate mortgages, have a
   specified maturity date, and the principal amount of the mortgage is repaid
   over the life of the mortgage. Unlike fixed rate mortgages, the interest rate
   on ARMs is adjusted at regular intervals based on a specified, published
   interest rate "index" such as a Treasury rate index. The new rate is
   determined by adding a specific interest amount, the "margin," to the
   interest rate of the index. Investment in ARM securities allows the Fund to
   participate in changing interest rate levels through regular adjustments in
   the coupons of the underlying mortgages, resulting in more variable current
   income and lower price volatility than longer-term fixed rate mortgage
   securities. The ARM securities in which the Fund expects to invest will
   generally adjust their interest rates at regular intervals of one year or
   less. ARM securities are a less effective means of locking in long-term rates
   than fixed rate mortgages since the income from adjustable rate mortgages
   will increase during periods of rising interest rates and decline during
   periods of falling rates.
 
  . Characteristics of Adjustable Rate Mortgage Securities The interest rates
   paid on the mortgages underlying ARM securities are reset at regular
   intervals by adding an interest rate margin to a specified interest rate
   index. There are three main categories of indices: those based on U.S.
   Treasury securities such as the constant maturity treasury rate (CMT); those
   derived from a calculated measure such as a cost of funds index (COFI) or a
   moving average of mortgage rates; and those based on certain actively traded
   or prominent short-term rates such as the LIBOR. Some indices, such as the
   one-year constant maturity Treasury rate, closely mirror changes in interest
   rate levels. Others, such as COFI, tend to lag behind changes in market rate
   levels but reset monthly, thus tending to be somewhat less volatile. Such a
   delay in adjusting to changes in interest rates may cause securities owned by
   the fund to increase or decrease in value, particularly during periods
   between interest adjustment dates.
 
   ARMs will frequently have caps and floors which limit the maximum amount by
   which the interest rate to the residential borrower may move up or down,
   respectively, each adjustment period and over the life of the loan. Interest
   rate caps on ARM securities may cause them to decrease in value in an
   increasing interest rate environment. Such caps may also prevent their income
   from increasing to levels commensurate with prevailing interest rates.
   Conversely, interest rate floors on ARM securities may cause their income to
   remain higher than prevailing interest rate levels and result in an increase
   in the value of such securities. However, this increase may be tempered by
   the acceleration of prepayments.
 
   Mortgage securities generally have a maximum maturity of up to 30 years.
   However due to the adjustable rate feature of ARM securities, their prices
   are considered to have volatility characteristics which approximate the
   average period of time until the next adjustment of the interest rate. As a
   result, the principal volatility of ARM securities may be more comparable to
   short- and intermediate-term securities than to longer term fixed rate
   mortgage securities. Prepayments however, will increase their principal
   volatility. See also the discussion of Mortgage-Backed Securities.
 
  . Other Mortgage-Related Securities The Fund expects that governmental,
   government-related or private entities may create mortgage loan pools
   offering pass-through investments in addition to those described above. The
   mortgages underlying these securities may be alternative mortgage
   instruments, that is, mortgage instruments whose principal or interest
   payments may vary or whose terms to maturity may differ from customary
   long-term fixed rate mortgages. As new types of mortgage-related securities
   are developed and offered to investors, the investment manager will,
   consistent with the Fund's objective, policies and quality standards,
   consider making investments in such new types of securities.

                               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"). Generally, a Hybrid Instrument will be a debt security,
   preferred stock,
 
 
<PAGE>
 
   depository share, trust certificate, certificate of deposit, or other
   evidence of indebtedness on which a portion of or all interest payments,
   and/or the principal or stated amount payable at maturity, redemption, or
   retirement, is determined by reference to prices, changes in prices, or
   differences between prices, of securities, currencies, intangibles, goods,
   articles, or commodities (collectively "Underlying Assets") or by another
   objective index, economic factor, or other measure, such as interest rates,
   currency exchange rates, commodity indices, and securities indices
   (collectively "Benchmarks"). 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.
 
   Hybrid Instruments can be an efficient means of creating exposure to a
   particular market, or segment of a market, with the objective of enhancing
   total return. For example, a Fund may wish to take advantage of expected
   declines in interest rates in several European countries, but avoid the
   transaction costs associated with buying and currency-hedging the foreign
   bond positions. One solution would be to purchase a U.S. dollar-denominated
   Hybrid Instrument whose redemption price is linked to the average three-year
   interest rate in a designated group of countries. The redemption price
   formula would provide for payoffs of greater than par if the average interest
   rate was lower than a specified level, and payoffs of less than par if rates
   were above the specified level. Furthermore, the Fund could limit the
   downside risk of the security by establishing a minimum redemption price so
   that the principal paid at maturity could not be below a predetermined
   minimum level if interest rates were to rise significantly. The purpose of
   this arrangement, known as a structured security with an embedded put option,
   would be to give the Fund the desired European bond exposure while avoiding
   currency risk, limiting downside market risk, and lowering transactions
   costs. Of course, there is no guarantee that the strategy will be successful,
   and the Fund could lose money if, for example, interest rates do not move as
   anticipated or credit problems develop with the issuer of the Hybrid.
 
   The risks of investing in Hybrid Instruments reflect a combination of the
   risks of investing in securities, options, futures and currencies. Thus, an
   investment in a Hybrid Instrument may entail significant risks that are not
   associated with a similar investment in a traditional debt instrument that
   has a fixed principal amount, is denominated in U.S. dollars, or bears
   interest either at a fixed rate or a floating rate determined by reference to
   a common, nationally published benchmark. The risks of a particular Hybrid
   Instrument will, of course, depend upon the terms of the instrument, but may
   include, without limitation, the possibility of significant changes in the
   Benchmarks or the prices of Underlying Assets to which the instrument is
   linked. Such risks generally depend upon factors which are unrelated to the
   operations or credit quality of the issuer of the Hybrid Instrument and which
   may not be readily foreseen by the purchaser, such as economic and political
   events, the supply and demand for the Underlying Assets, and interest rate
   movements. In recent years, various Benchmarks and prices for Underlying
   Assets have been highly volatile, and such volatility may be expected in the
   future. Reference is also made to the discussion of futures, options, and
   forward contracts herein for a discussion of the risks associated with such
   investments.
 
   Hybrid Instruments are potentially more volatile and carry greater market
   risks than traditional debt instruments. Depending on the structure of the
   particular Hybrid Instrument, changes in a Benchmark may be magnified by the
   terms of the Hybrid Instrument and have an even more dramatic and substantial
   effect upon the value of the Hybrid Instrument. Also, the prices of the
   Hybrid Instrument and the Benchmark or Underlying Asset 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). The latter scenario may result if "leverage" is
   used to structure the Hybrid Instrument. Leverage risk occurs when the Hybrid
   Instrument is structured so that a given change in a Benchmark or Underlying
   Asset is multiplied to produce a greater value change in the Hybrid
   Instrument, thereby magnifying the risk of loss as well as the potential for
   gain.
 
   
   Hybrid Instruments may also carry liquidity risk since the instruments are
   often "customized" to meet the portfolio needs of a particular investor, and
   therefore, the number of investors that are willing and able to buy    
 
 
<PAGE>
 
   
   such instruments in the secondary market may be smaller than that for more
   traditional debt securities. In addition, because the purchase and sale of
   Hybrid Instruments could take place in an over-the-counter market without the
   guarantee of a central clearing organization or in a transaction between the
   Fund and the issuer of the Hybrid Instrument, the creditworthiness of the
   counter party of issuer of the Hybrid Instrument would be an additional risk
   factor which the Fund would have to consider and monitor. 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.    
 
   The various risks discussed above, particularly the market risk of such
   instruments, may in turn cause significant fluctuations in the net asset
   value of the Fund. Accordingly, the Fund will limit its investments in Hybrid
   Instruments to 10% of total assets. However, because of their volatility, it
   is possible that the Fund's investment in Hybrid Instruments will account for
   more than 10% of the Fund's return (positive or negative).
 
   All Summit Municipal Funds
 
 
                               Types of Securities
 
   Set forth below is additional information about certain of the investments
   described in the Fund's prospectus.
 
 
                              Municipal Securities
 
   Subject to the investment objectives and programs described in the prospectus
   and the additional investment restrictions described in this Statement of
   Additional Information, each Fund's portfolio may consist of any combination
   of the various types of municipal securities described below or other types
   of municipal securities that may be developed. The amount of each Fund's
   assets invested in any particular type of municipal security can be expected
   to vary.
 
   The term "municipal securities" means obligations issued by or on behalf of
   states, territories, and possessions of the United States and the District of
   Columbia and their political subdivisions, agencies and instrumentalities, as
   well as certain other persons and entities, the interest from which is exempt
   from federal income tax. In determining the tax-exempt status of a municipal
   security, the Fund relies on the opinion of the issuer's bond counsel at the
   time of the issuance of the security. However, it is possible this opinion
   could be overturned, and as a result, the interest received by the Fund from
   such a security might not be exempt from federal income tax.
 
   Municipal securities are classified by maturity as notes, bonds, or
   adjustable rate securities.
 
 
                                 Municipal Notes
 
   Municipal notes generally are used to provide short-term operating or capital
   needs and generally have maturities of one year or less. Municipal notes
   include:
 
  . Tax Anticipation Notes Tax anticipation notes are issued to finance working
   capital needs of municipalities. Generally, they are issued in anticipation
   of various seasonal tax revenue, such as income, property, use and business
   taxes, and are payable from these specific future taxes.
 
  . Revenue Anticipation Notes Revenue anticipation notes are issued in
   expectation of receipt of other types of revenue, such as federal or state
   revenues available under the revenue sharing or grant programs.
 
  . Bond Anticipation Notes Bond anticipation notes are issued to provide
   interim financing until long-term financing can be arranged. In most cases,
   the long-term bonds then provide the money for the repayment of the notes.
 
  . Tax-Exempt Commercial Paper Tax-exempt commercial paper is a short-term
   obligation with a stated maturity of 270 days or less. It is issued by state
   and local governments or their agencies to finance seasonal working capital
   need or as short-term financing in anticipation of longer-term financing.
 
  . Municipal Bonds Municipal bonds, which meet longer-term capital needs and
   generally have maturities of more than one year when issued, have two
   principal classifications: general obligation bonds and revenue
 
 
<PAGE>
 
   bonds. Two additional categories of potential purchases are lease revenue
   bonds and pre-refunded/escrowed to maturity bonds. Another type of municipal
   bond is referred to as an Industrial Development Bond.
 
  . General Obligation Bonds Issuers of general obligation bonds include states,
   counties, cities, towns, and special districts. The proceeds of these
   obligations are used to Fund a wide range of public projects, including
   construction or improvement of schools, public buildings, highways and roads,
   and general projects not supported by user fees or specifically identified
   revenues. The basic security behind general obligation bonds is the issuer's
   pledge of its full faith and credit and taxing power for the payment of
   principal and interest. The taxes that can be levied for the payment of debt
   service may be limited or unlimited as to the rate or amount of special
   assessments. In many cases voter approval is required before an issuer may
   sell this type of bond.
 
  . Revenue Bonds The principal security for a revenue bond is generally the net
   revenues derived from a particular facility, or enterprise, or in some cases,
   the proceeds of a special charge or other pledged revenue source. Revenue
   bonds are issued to finance a wide variety of capital projects including:
   electric, gas, water and sewer systems; highways, bridges, and tunnels; port
   and airport facilities; colleges and universities; and hospitals. Revenue
   bonds are sometimes used to finance various privately operated facilities
   provided they meet certain tests established for tax-exempt status.
 
   Although the principal security behind these bonds may vary, many provide
   additional security in the form of a mortgage or debt service reserve Fund.
   Some authorities provide further security in the form of the state's ability
   (without obligation) to make up deficiencies in the debt service reserve
   Fund. Revenue bonds usually do not require prior voter approval before they
   may be issued.
 
  . Lease Revenue Bonds Municipal borrowers may also finance capital
   improvements or purchases with tax-exempt leases. The security for a lease is
   generally the borrower's pledge to make annual appropriations for lease
   payments. The lease payment is treated as an operating expense subject to
   appropriation risk and not a full faith and credit obligation of the issuer.
   Lease revenue bonds are generally considered less secure than a general
   obligation or revenue bond and often do not include a debt service reserve
   Fund. To the extent the Fund's Board determines such securities are illiquid,
   they will be subject to the Fund's limit on illiquid securities. There have
   also been certain legal challenges to the use of lease revenue bonds in
   various states.
 
   The liquidity of such securities will be determined based on a variety of
   factors which may include, among others: (1) the frequency of trades and
   quotes for the obligation; (2) the number of dealers willing to purchase or
   sell the security and the number of other potential buyers; (3) the
   willingness of dealers to undertake to make a market in the security; (4) the
   nature of the marketplace trades, including the time needed to dispose of the
   security, the method of soliciting offers, and the mechanics of transfer; and
   (5) the rating assigned to the obligation by an established rating agency or
   T. Rowe Price.
 
  . Pre-refunded/Escrowed to Maturity Bonds Certain municipal bonds have been
   refunded with a later bond issue from the same issuer. The proceeds from the
   later issue are used to defease the original issue. In many cases the
   original issue cannot be redeemed or repaid until the first call date or
   original maturity date. In these cases, the refunding bond proceeds typically
   are used to buy U.S. Treasury securities that are held in an escrow account
   until the original call date or maturity date. The original bonds then become
   "pre-refunded" or "escrowed to maturity" and are considered as high-quality
   investments. While still tax-exempt, the security is the proceeds of the
   escrow account. To the extent permitted by the SEC and the Internal Revenue
   Service, a Fund's investment in such securities refunded with U.S. Treasury
   securities will, for purposes of diversification rules applicable to the
   Fund, be considered as an investment in the U. S. Treasury securities.
 
  . Private Activity Bonds Under current tax law all municipal debt is divided
   broadly into two groups: governmental purpose bonds and private activity
   bonds. Governmental purpose bonds are issued to finance traditional public
   purpose projects such as public buildings and roads. Private activity bonds
   may be issued by a state or local government or public authority but
   principally benefit private users and are considered taxable unless a
   specific exemption is provided.
 
 
<PAGE>
 
   The tax code currently provides exemptions for certain private activity bonds
   such as not-for-profit hospital bonds, small-issue industrial development
   revenue bonds and mortgage subsidy bonds, which may still be issued as
   tax-exempt bonds. Some, but not all, private activity bonds are subject to
   alternative minimum tax.
 
  . Industrial Development Bonds Industrial development bonds are considered
   Municipal Bonds if the interest paid is exempt from federal income tax. They
   are issued by or on behalf of public authorities to raise money to finance
   various privately operated facilities for business and manufacturing,
   housing, sports, and pollution control. These bonds are also used to finance
   public facilities such as airports, mass transit systems, ports, and parking.
   The payment of the principal and interest on such bonds is dependent solely
   on the ability of the facility's user to meet its financial obligations and
   the pledge, if any, of real and personal property so financed as security for
   such payment.
 
 
                           Adjustable Rate Securities
 
   Generally, the maturity of a security is deemed to be the period remaining
   until the date (noted on the face of the instrument) on which the principal
   amount must be paid, or in the case of an instrument called for redemption,
   the date on which the redemption payment must be made. However, certain
   securities may be issued with adjustable interest rates that are reset
   periodically by predetermined formulas or indexes in order to minimize
   movements in the principal value of the investment. In accordance with Rule
   2a-7 under the 1940 Act. Such securities may have long-term maturities, but
   may be treated as a short-term investment under certain conditions.
   Generally, as interest rates decrease or increase, the potential for capital
   appreciation or depreciation on these securities is less than for fixed rate
   obligations. These securities may take the following forms:
 
  . Variable Rate Securities A variable rate instrument is one whose terms
   provide for the adjustment of its interest rate on set dates and which, upon
   each adjustment until the final maturity of the instrument or the period
   remaining until the principal amount can be recovered through demand, can
   reasonably be expected to have a market value which approximates its
   amortized cost. A variable rate instrument, the principal amount of which is
   scheduled to be paid in 397 calendar days or less, is deemed to have a
   maturity equal to the earlier of the period remaining until the next
   readjustment of the interest rate or the period remaining until the principal
   amount can be recovered through demand. A variable rate instrument the
   principal amount of which is scheduled to be paid in more than 397 calendar
   days and which is subject to a demand feature which entitles the purchaser to
   receive the principal amount of the underlying security or securities, either
   (i) at any time upon notice of no more than 30 days, or (ii) at specified
   intervals not exceeding 397 calendar days and upon no more than 30 days'
   notice ("Demand Feature"), is deemed to have a maturity equal to the longer
   of the period remaining until the next readjustment of the interest rate or
   the period remaining until the principal amount can be recovered through
   demand. A government security that is a variable rate security where the
   variable rate is readjusted no less frequently than every 762 calendar days
   is deemed to have a maturity equal to the period remaining until the next
   readjustment of the interest rate.
 
  . Floating Rate Securities A floating rate security provides for the
   adjustment of its interest rates whenever a specified interest rate changes
   and which, at any time until the final maturity of the instrument or the
   period remaining until the principal amount can be recovered through demand,
   can reasonably be expected to have a market value that approximates its
   amortized cost. A floating rate security, the principal amount of which must
   unconditionally be paid in 397 calendar days or less is deemed to have a
   maturity of one day. A floating rate security, the principal amount of which
   is scheduled to be paid in more than 397 calendar days, that is subject to a
   Demand Feature is deemed to have a maturity equal to the period remaining
   until the principal amount can be recovered through demand. A government
   security that is a floating rate security is deemed to have a remaining
   maturity of one day.
 
  . Put Option Bonds Long-term obligations with maturities longer than one year
   may provide purchasers an optional or mandatory tender of the security at par
   value at predetermined intervals, often ranging from one month to several
   years (e.g., a 30-year bond with a five-year tender period). These
   instruments are deemed to have a maturity equal to the period remaining to
   the put date.
 
 
<PAGE>
 
  . Participation Interests The Funds may purchase from third parties
   participation interests in all or part of specific holdings of municipal
   securities. The purchase may take different forms: in the case of short-term
   securities, the participation may be backed by a liquidity facility that
   allows the interest to be sold back to the third party (such as a trust,
   broker or bank) for a predetermined price of par at stated intervals. The
   seller may receive a fee from the Funds in connection with the arrangement.
 
   In the case of longer-term bonds, the Funds may purchase interests in a pool
   of municipal bonds or a single municipal bond or lease without the right to
   sell the interest back to the third party.
 
   The Funds will not purchase participation interests unless a satisfactory
   opinion of counsel or ruling of the Internal Revenue Service has been issued
   that the interest earned from the municipal securities on which the Funds
   holds participation interests is exempt from federal income tax to the Funds.
   However, there is no guarantee the IRS would treat such interest income as
   tax-exempt.
 
 
                             When-Issued Securities
 
   New issues of municipal securities are often offered on a when-issued basis;
   that is, delivery and payment for the securities normally takes place 15 to
   45 days or more after the date of the commitment to purchase. The payment
   obligation and the interest rate that will be received on the securities are
   each fixed at the time the buyer enters into the commitment. A Fund will only
   make a commitment to purchase such securities with the intention of actually
   acquiring the securities. However, a Fund may sell these securities before
   the settlement date if it is deemed advisable as a matter of investment
   strategy. Each Fund will maintain cash, high-grade marketable debt securities
   or other suitable cover with its custodian bank equal in value to commitments
   for when-issued securities. Such securities either will mature or, if
   necessary, be sold on or before the settlement date. Securities purchased on
   a when-issued basis and the securities held in a Fund's portfolio are subject
   to changes in market value based upon the public perception of the
   creditworthiness of the issuer and changes in the level of interest rates
   (which will generally result in similar changes in value, i.e., both
   experiencing appreciation when interest rates decline and depreciation when
   interest rates rise). Therefore, to the extent a Fund remains fully invested
   or almost fully invested at the same time that it has purchased securities on
   a when-issued basis, there will be greater fluctuations in its net asset
   value than if it solely set aside cash to pay for when-issued securities. In
   the case of the Money Fund, this could increase the possibility that the
   market value of the Fund's assets could vary from $1.00 per share. In
   addition, there will be a greater potential for the realization of capital
   gains, which are not exempt from federal income tax. When the time comes to
   pay for when-issued securities, a Fund will meet its obligations from
   then-available cash flow, sale of securities or, although it would not
   normally expect to do so, from sale of the when-issued securities themselves
   (which may have a value greater or less than the payment obligation). The
   policies described in this paragraph are not fundamental and may be changed
   by a Fund upon notice to its shareholders.
 
 
                  Investment in Taxable Money Market Securities
 
   Although the Funds expect to be solely invested in municipal securities, for
   temporary defensive purposes they may elect to invest in the taxable money
   market securities listed below (without limitation) when such action is
   deemed to be in the best interests of shareholders. The interest earned on
   these money market securities is not exempt from federal income tax and may
   be taxable to shareholders as ordinary income.
 
  . U.S. Government Obligations Bills, notes, bonds, and other debt securities
   issued by the U.S. Treasury. These are direct obligations of the U.S.
   government and differ mainly in the length of their maturities.
 
  . U.S. Government Agency Securities Issued or guaranteed by U.S.
   government-sponsored enterprises and federal agencies. These include
   securities issued by the Federal National Mortgage Association, Government
   National Mortgage Association, Federal Home Loan Bank, Federal Land Banks,
   Farmers Home Administration, Banks for Cooperatives, Federal Intermediate
   Credit Banks, Federal Financing Bank, Farm Credit Banks, the Small Business
   Association, and the Tennessee Valley Authority. Some of these securities are
   supported by the full faith and credit of the U.S. Treasury; the remainder
   are supported only by the credit of the instrumentality, which may or may not
   include the right of the issuer to borrow from the Treasury.
 
 
<PAGE>
 
  . Bank Obligations Certificates of deposit, bankers' acceptances, and other
   short-term debt obligations. Certificates of deposit are short-term
   obligations of commercial banks. A bankers' acceptance is a time draft drawn
   on a commercial bank by a borrower, usually in connection with international
   commercial transactions. Certificates of deposit may have fixed or variable
   rates. The Fund may invest in U.S. banks, foreign branches of U.S. banks,
   U.S. branches of foreign banks, and foreign branches of foreign banks.
 
  . Short-Term Corporate Debt Securities Outstanding nonconvertible corporate
   debt securities (e.g., bonds and debentures) which have one year or less
   remaining to maturity. Corporate notes may have fixed, variable, or floating
   rates.
 
  . Commercial Paper Short-term promissory notes issued by corporations
   primarily to finance short-term credit needs. Certain notes may have floating
   or variable rates.
 
  . Foreign Government Securities Issued or guaranteed by a foreign government,
   province, instrumentality, political subdivision, or similar unit thereof.
 
  . Savings and Loan Obligations Negotiable certificates of deposit and other
   short-term debt obligations of savings and loan associations.
 
  . Supranational Agencies Securities of certain supranational entities, such as
   the International Development Bank.
 
  . Determination of Maturity of Money Market Securities The Money Fund may only
   purchase securities which at the time of investment have remaining maturities
   of 397 calendar days or less. The other Funds may also purchase money market
   securities. In determining the maturity of money market securities, Funds
   will follow the provisions of Rule 2a-7 under the 1940 Act.
 
   Intermediate and Income Funds
 
  . Residual Interest Bonds are a type of high-risk derivative. The Funds may
   purchase municipal bond issues that are structured as two-part, residual
   interest bond and variable rate security offerings. The issuer is obligated
   only to pay a fixed amount of tax-free income that is to be divided among the
   holders of the two securities. The interest rate for the holders of the
   variable rate securities will be determined by an index or auction process
   held approximately every seven to 35 days while the bondholders will receive
   all interest paid by the issuer minus the amount given to the variable rate
   security holders and a nominal auction fee. Therefore, the coupon of the
   residual interest bonds, and thus the income received, will move inversely
   with respect to short-term, seven- to 35-day tax-exempt interest rates. There
   is no assurance that the auction will be successful and that the variable
   rate security will provide short-term liquidity. The issuer is not obligated
   to provide such liquidity. In general, these securities offer a significant
   yield advantage over standard municipal securities, due to the uncertainty of
   the shape of the yield curve (i.e., short-term versus long-term rates) and
   consequent income flows.
 
   Unlike many adjustable rate securities, residual interest bonds are not
   necessarily expected to trade at par and in fact present significant market
   risks. In certain market environments, residual interest bonds may carry
   substantial premiums or be at deep discounts. This is a relatively new
   product in the municipal market with limited liquidity to date.
 
  . Embedded Interest Rate Swaps and Caps In a fixed rate, long-term municipal
   bond with an interest rate swap attached to it, the bondholder usually
   receives the bond's fixed coupon payment as well as a variable rate payment
   that represents the difference between a fixed rate for the term of the swap
   (which is typically shorter than the bond it is attached to) and a variable
   rate, short-term municipal index. The bondholder receives excess income when
   short-term rates remain below the fixed interest rate swap rate. If
   short-term rates rise above the fixed income swap rate, the bondholder's
   income is reduced. At the end of the interest rate swap term, the bond
   reverts to a single fixed coupon payment. Embedded interest rate swaps
   enhance yields, but also increase interest rate risk.
 
   An embedded interest rate cap allows the bondholder to receive payments
   whenever short-term rates rise above a level established at the time of
   purchase. They normally are used to hedge against rising short-term
 
 
<PAGE>
 
   interest rates. Both instruments may be volatile and of limited liquidity,
   and their use may adversely affect the Fund's total return. Each Fund will
   not invest more than 5% of its total assets in these instruments.
 
   The Funds may invest in other types of derivative instruments as they become
   available.
 
   For the purpose of the Funds' investment restrictions, the identification of
   the "issuer" of municipal securities which are not general obligation bonds
   is made by the Funds' investment manager, T. Rowe Price, on the basis of the
   characteristics of the obligation as described above, the most significant of
   which is the source of Funds for the payment of principal and interest on
   such 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.
 
   Intermediate and Income Funds
 
 
                                    Forwards
 
   The Funds may purchase bonds on a when-issued basis with longer than standard
   settlement dates, in some cases exceeding one to two years. In such cases,
   the Funds must execute a receipt evidencing the obligation to purchase the
   bond on the specified issue date, and must segregate cash internally to meet
   that forward commitment. Municipal "forwards" typically carry a substantial
   yield premium to compensate the buyer for the risks associated with a long
   when-issued period, including: shifts in market interest rates that could
   materially impact the principal value of the bond, deterioration in the
   credit quality of the issuer, loss of alternative investment options during
   the when-issued period, changes in tax law or issuer actions that would
   affect the exempt interest status of the bonds and prevent delivery, failure
   of the issuer to complete various steps required to issue the bonds, and
   limited liquidity for the buyer to sell the escrow receipts during the
   when-issued period.
 
 
 
 PORTFOLIO MANAGEMENT PRACTICES
 -------------------------------------------------------------------------------
   All Funds
 
 
                         Lending of Portfolio Securities
 
   Securities loans are made to broker-dealers or institutional investors or
   other persons, pursuant to agreements requiring that the loans be
   continuously secured by collateral at least equal at all times to the value
   of the securities lent, marked to market on a daily basis. The collateral
   received will consist of cash, U.S. government securities, letters of credit
   or such other collateral as may be permitted under its investment program.
   While the securities are being lent, the Fund will continue to receive the
   equivalent of the interest or dividends paid by the issuer on the securities,
   as well as interest on the investment of the collateral or a fee from the
   borrower. The Fund has a right to call each loan and obtain the securities,
   within such period of time which coincides with the normal settlement period
   for purchases and sales of such securities in the respective markets. The
   Fund will not have the right to vote on securities while they are being lent,
   but it will call a loan in anticipation of any important vote. The risks in
   lending portfolio securities, as with other extensions of secured credit,
   consist of possible delay in receiving additional collateral or in the
   recovery of the securities or possible loss of rights in the collateral
   should the borrower fail financially. Loans will only be made to firms deemed
   by T. Rowe Price to be of good standing and will not be made unless, in the
   judgment of T. Rowe Price, the consideration to be earned from such loans
   would justify the risk.
 
 
                         Interfund Borrowing and Lending
 
   
   The Fund is a party to an exemptive order received from the SEC on December
   8, 1998, that permits it to borrow money from and/or lend money to other
   funds in the T. Rowe Price complex ("Price Funds"). All loans are set at an
   interest rate between the rate charged on overnight repurchase agreements and
   short-term bank loans. All loans are subject to numerous conditions designed
   to ensure fair and equitable treatment of all    
 
 
<PAGE>
 
   
   participating funds. The program is subject to the oversight and periodic
   review of the Boards of Directors of the Price Funds.    
 
 
                              Repurchase Agreements
 
   Each Fund may enter into repurchase agreements through which investors (such
   as the Fund) purchases a security (the "underlying security") from a
   well-established securities dealer or a bank which is a member of the Federal
   Reserve System. Any such dealer or bank will be on T. Rowe Price's approved
   list.   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. Each Fund will only enter into repurchase
   agreements where (i) (A) Cash Reserves Fund--the underlying securities are
                            ------------------
   either U.S. government securities or securities that, at the time the
   repurchase agreement is entered into, are rated in the highest rating
   category by the requisite number of NRSROs (as required by Rule 2a-7 under
   the 1940 Act) and otherwise are of the type (excluding maturity limitations)
   which the Fund's investment guidelines would allow it to purchase directly
   (however, the underlying securities will either be U.S. government securities
   or securities which, at the time the repurchase agreement is entered into,
   are rated in the highest rating category by public rating agencies), (B)
   Limited-Term and GNMA Funds--the underlying securities are of the type
   ---------------------------
   (excluding maturity limitations) which each 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 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,
   a 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.
 
 
                          Reverse Repurchase Agreements
 
   Although the Fund has no current intention of engaging in reverse repurchase
   agreements, the Fund reserves the right to do so. Reverse repurchase
   agreements are ordinary repurchase agreements in which a Fund is the seller
   of, rather than the investor in, securities, and agrees to repurchase them at
   an agreed upon time and price. Use of a reverse repurchase agreement may be
   preferable to a regular sale and later repurchase of the securities because
   it avoids certain market risks and transaction costs. A reverse repurchase
   agreement may be viewed as a type of borrowing by the Fund, subject to
   Investment Restriction (1). (See "Investment Restrictions.")
 
   Limited-Term Bond and GNMA Funds
 
 
                              Money Market Reserves
 
   It is expected that the Fund will invest its cash reserves primarily in one
   or more money market funds established for the exclusive use of the T. Rowe
   Price family of mutual funds and other clients of T. Rowe Price and
   Price-Fleming. Currently, two such money market funds are in
   operation-Reserve Investment Fund ("RIF") and Government Reserve Investment
   Fund ("GRF"), each a series of the Reserve Investment Funds, Inc. Additional
   series may be created in the future. These funds were created and operate
   under an Exemptive Order issued by the SEC (Investment Company Act Release
   No. IC-22770, July 29, 1997).
 
   Both funds must comply with the requirements of Rule 2a-7 under the 1940 Act
   governing money market funds. The RIF invests at least 95% of its total
   assets in prime money market instruments receiving the highest credit rating.
   The GRF invests primarily in a portfolio of U.S. government-backed
   securities, primarily U.S. Treasuries, and repurchase agreements thereon.
 
   The RIF and GRF provide a very efficient means of managing the cash reserves
   of the Fund. While neither RIF or GRF pay an advisory fee to the Investment
   Manager, they will incur other expenses. However, the RIF and
 
 
<PAGE>
 
   GRF are expected by T. Rowe Price to operate at very low expense ratios. The
   Fund will only invest in RIF or GRF to the extent it is consistent with its
   objective and program.
 
   Neither fund is insured or guaranteed by the U.S. government, and there is no
   assurance they will maintain a stable net asset value of $1.00 per share.

   Limited-Term Bond and GNMA Funds
 
 
                          Writing Covered Call Options
 
   The Fund may write (sell) American or European style "covered" call options
   and purchase options to close out options previously written by the Fund. In
   writing covered call options, the Fund expects to generate additional premium
   income which should serve to enhance the Fund's total return and reduce the
   effect of any price decline of the security or currency involved in the
   option. Covered call options will generally be written on securities or
   currencies which, in T. Rowe Price's opinion, are not expected to have any
   major price increases or moves in the near future but which, over the long
   term, are deemed to be attractive investments for the Fund.
 
   A call option gives the holder (buyer) the "right to purchase" a security or
   currency at a specified price (the exercise price) at expiration of the
   option (European style) or at any time until a certain date (the expiration
   date) (American style). So long as the obligation of the writer of a call
   option continues, he may be assigned an exercise notice by the broker-dealer
   through whom such option was sold, requiring him to deliver the underlying
   security or currency against payment of the exercise price. This obligation
   terminates upon the expiration of the call option, or such earlier time at
   which the writer effects a closing purchase transaction by repurchasing an
   option identical to that previously sold. To secure his obligation to deliver
   the underlying security or currency in the case of a call option, a writer is
   required to deposit in escrow the underlying security or currency or other
   assets in accordance with the rules of a clearing corporation.
 
   The Fund will write only covered call options. This means that the Fund will
   own the security or currency subject to the option or an option to purchase
   the same underlying security or currency, having an exercise price equal to
   or less than the exercise price of the "covered" option, or will establish
   and maintain with its custodian for the term of the option, an account
   consisting of cash, U.S. government securities, other liquid high-grade debt
   obligations, or other suitable cover as permitted by the SEC having a value
   equal to the fluctuating market value of the optioned securities or
   currencies.
 
   Portfolio securities or currencies on which call options may be written will
   be purchased solely on the basis of investment considerations consistent with
   the Fund's investment objective. The writing of covered call options is a
   conservative investment technique believed to involve relatively little risk
   (in contrast to the writing of naked or uncovered options, which the Fund
   will not do), but capable of enhancing the Fund's total return. When writing
   a covered call option, a Fund, in return for the premium, gives up the
   opportunity for profit from a price increase in the underlying security or
   currency above the exercise price, but conversely retains the risk of loss
   should the price of the security or currency decline. Unlike one who owns
   securities or currencies not subject to an option, the Fund has no control
   over when it may be required to sell the underlying securities or currencies,
   since it may be assigned an exercise notice at any time prior to the
   expiration of its obligation as a writer. If a call option which the Fund has
   written expires, the Fund will realize a gain in the amount of the premium;
   however, such gain may be offset by a decline in the market value of the
   underlying security or currency during the option period. If the call option
   is exercised, the Fund will realize a gain or loss from the sale of the
   underlying security or currency. The Fund does not consider a security or
   currency covered by a call to be "pledged" as that term is used in the Fund's
   policy which limits the pledging or mortgaging of its assets.
 
   The premium received is the market value of an option. The premium the Fund
   will receive from writing a call option will reflect, among other things, the
   current market price of the underlying security or currency, the relationship
   of the exercise price to such market price, the historical price volatility
   of the underlying
 
 
<PAGE>
 
   security or currency, and the length of the option period. Once the decision
   to write a call option has been made, T. Rowe Price, in determining whether a
   particular call option should be written on a particular security or
   currency, will consider the reasonableness of the anticipated premium and the
   likelihood that a liquid secondary market will exist for those options. The
   premium received by the Fund for writing covered call options will be
   recorded as a liability of the Fund. This liability will be adjusted daily to
   the option's current market value, which will be the latest sale price at the
   time at which the net asset value per share of the Fund is computed (close of
   the New York Stock Exchange), or, in the absence of such sale, the latest
   asked price. The option will be terminated upon expiration of the option, the
   purchase of an identical option in a closing transaction, or delivery of the
   underlying security or currency upon the exercise of the option.
 
   Closing transactions will be effected in order to realize a profit on an
   outstanding call option, to prevent an underlying security or currency from
   being called, or, to permit the sale of the underlying security or currency.
   Furthermore, effecting a closing transaction will permit the Fund to write
   another call option on the underlying security or currency with either a
   different exercise price or expiration date or both. If the Fund desires to
   sell a particular security or currency from its portfolio on which it has
   written a call option, or purchased a put option, it will seek to effect a
   closing transaction prior to, or concurrently with, the sale of the security
   or currency. There is, of course, no assurance that the Fund will be able to
   effect such closing transactions at favorable prices. If the Fund cannot
   enter into such a transaction, it may be required to hold a security or
   currency that it might otherwise have sold. When the Fund writes a covered
   call option, it runs the risk of not being able to participate in the
   appreciation of the underlying securities or currencies above the exercise
   price, as well as the risk of being required to hold on to securities or
   currencies that are depreciating in value. This could result in higher
   transaction costs. The Fund will pay transaction costs in connection with the
   writing of options to close out previously written options. Such transaction
   costs are normally higher than those applicable to purchases and sales of
   portfolio securities.
 
   Call options written by the Fund will normally have expiration dates of less
   than nine months from the date written. The exercise price of the options may
   be below, equal to, or above the current market values of the underlying
   securities or currencies at the time the options are written. From time to
   time, the Fund may purchase an underlying security or currency for delivery
   in accordance with an exercise notice of a call option assigned to it, rather
   than delivering such security or currency from its portfolio. In such cases,
   additional costs may be incurred.
 
   The Fund will realize a profit or loss from a closing purchase transaction if
   the cost of the transaction is less or more than the premium received from
   the writing of the option. Because increases in the market price of a call
   option will generally reflect increases in the market price of the underlying
   security or currency, any loss resulting from the repurchase of a call option
   is likely to be offset in whole or in part by appreciation of the underlying
   security or currency owned by the Fund.
 
   The Fund will not write a covered call option if, as a result, the aggregate
   market value of all portfolio securities or currencies covering written call
   or put options exceeds 25% of the market value of the Fund's net assets. In
   calculating the 25% limit, the Fund will offset, against the value of assets
   covering written calls and puts, the value of purchased calls and puts on
   identical securities or currencies with identical maturity dates.
 
 
                           Writing Covered Put Options
 
   The Fund may write American or European style covered put options and
   purchase options to close out options previously written by the Fund. A put
   option gives the purchaser of the option the right to sell, and the writer
   (seller) has the obligation to buy, the underlying security or currency at
   the exercise price during the option period (American style) or at the
   expiration of the option (European style). So long as the obligation of the
   writer continues, he may be assigned an exercise notice by the broker-dealer
   through whom such option was sold, requiring him to make payment to the
   exercise price against delivery of the underlying security or currency. The
   operation of put options in other respects, including their related risks and
   rewards, is substantially identical to that of call options.
 
   The Fund would write put options only on a covered basis, which means that
   the Fund would maintain in a segregated account cash, U.S. government
   securities, other liquid high-grade debt obligations, or other
 
 
<PAGE>
 
   suitable cover as determined by the SEC, in an amount not less than the
   exercise price or the Fund will own an option to sell the underlying security
   or currency subject to the option having an exercise price equal to or
   greater than the exercise price of the "covered" option at all times while
   the put option is outstanding. (The rules of a clearing corporation currently
   require that such assets be deposited in escrow to secure payment of the
   exercise price.)
 
   The Fund would generally write covered put options in circumstances where T.
   Rowe Price wishes to purchase the underlying security or currency for the
   Fund's portfolio at a price lower than the current market price of the
   security or currency. In such event the Fund would write a put option at an
   exercise price which, reduced by the premium received on the option, reflects
   the lower price it is willing to pay. Since the Fund would also receive
   interest on debt securities or currencies maintained to cover the exercise
   price of the option, this technique could be used to enhance current return
   during periods of market uncertainty. The risk in such a transaction would be
   that the market price of the underlying security or currency would decline
   below the exercise price less the premiums received. Such a decline could be
   substantial and result in a significant loss to the Fund. In addition, the
   Fund, because it does not own the specific securities or currencies which it
   may be required to purchase in exercise of the put, cannot benefit from
   appreciation, if any, with respect to such specific securities or currencies.
 
   The Fund will not write a covered put option if, as a result, the aggregate
   market value of all portfolio securities or currencies covering put or call
   options exceeds 25% of the market value of the Fund's net assets. In
   calculating the 25% limit, the Fund will offset, against the value of assets
   covering written puts and calls, the value of purchased puts and calls on
   identical securities or currencies with identical maturity dates.
 
 
                             Purchasing Put Options
 
   The Fund may purchase American or European style put options. As the holder
   of a put option, the Fund has the right to sell the underlying security or
   currency at the exercise price at any time during the option period (American
   style) or at the expiration of the option (European style). The Fund may
   enter into closing sale transactions with respect to such options, exercise
   them or permit them to expire. The Fund may purchase put options for
   defensive purposes in order to protect against an anticipated decline in the
   value of its securities or currencies. An example of such use of put options
   is provided next.
 
   The Fund may purchase a put option on an underlying security or currency (a
   "protective put") owned by the Fund as a defensive technique in order to
   protect against an anticipated decline in the value of the security or
   currency. Such hedge protection is provided only during the life of the put
   option when the Fund, as the holder of the put option, is able to sell the
   underlying security or currency at the put exercise price regardless of any
   decline in the underlying security's market price or currency's exchange
   value. For example, a put option may be purchased in order to protect
   unrealized appreciation of a security or currency where T. Rowe Price deems
   it desirable to continue to hold the security or currency because of tax
   considerations. The premium paid for the put option and any transaction costs
   would reduce any capital gain otherwise available for distribution when the
   security or currency is eventually sold.
 
   The Fund may also purchase put options at a time when the Fund does not own
   the underlying security or currency. By purchasing put options on a security
   or currency it does not own, the Fund seeks to benefit from a decline in the
   market price of the underlying security or currency. If the put option is not
   sold when it has remaining value, and if the market price of the underlying
   security or currency remains equal to or greater than the exercise price
   during the life of the put option, the Fund will lose its entire investment
   in the put option. In order for the purchase of a put option to be
   profitable, the market price of the underlying security or currency must
   decline sufficiently below the exercise price to cover the premium and
   transaction costs, unless the put option is sold in a closing sale
   transaction.
 
   The Fund will not commit more than 5% of its assets to premiums when
   purchasing put and call options. The premium paid by the Fund when purchasing
   a put option will be recorded as an asset of the Fund. This asset will be
   adjusted daily to the option's current market value, which will be the latest
   sale price at the time at which the net asset value per share of the Fund is
   computed (close of New York Stock Exchange), or, in the absence of such sale,
   the latest bid price. This asset will be terminated upon expiration of the
   option, the
 
 
<PAGE>
 
   selling (writing) of an identical option in a closing transaction, or the
   delivery of the underlying security or currency upon the exercise of the
   option.
 
 
                             Purchasing Call Options
 
   The Fund may purchase American or European style call options. As the holder
   of a call option, the Fund has the right to purchase the underlying security
   or currency at the exercise price at any time during the option period
   (American style) or at the expiration of the option (European style). The
   Fund may enter into closing sale transactions with respect to such options,
   exercise them or permit them to expire. The Fund may purchase call options
   for the purpose of increasing its current return or avoiding tax consequences
   which could reduce its current return. The Fund may also purchase call
   options in order to acquire the underlying securities or currencies. Examples
   of such uses of call options are provided next.
 
   Call options may be purchased by the Fund for the purpose of acquiring the
   underlying securities or currencies for its portfolio. Utilized in this
   fashion, the purchase of call options enables the Fund to acquire the
   securities or currencies at the exercise price of the call option plus the
   premium paid. At times the net cost of acquiring securities or currencies in
   this manner may be less than the cost of acquiring the securities or
   currencies directly. This technique may also be useful to the Fund in
   purchasing a large block of securities or currencies that would be more
   difficult to acquire by direct market purchases. So long as it holds such a
   call option rather than the underlying security or currency itself, the Fund
   is partially protected from any unexpected decline in the market price of the
   underlying security or currency and in such event could allow the call option
   to expire, incurring a loss only to the extent of the premium paid for the
   option.
 
   The Fund will not commit more than 5% of its assets to premiums when
   purchasing call and put options. The Fund may also purchase call options on
   underlying securities or currencies it owns in order to protect unrealized
   gains on call options previously written by it. A call option would be
   purchased for this purpose where tax considerations make it inadvisable to
   realize such gains through a closing purchase transaction. Call options may
   also be purchased at times to avoid realizing losses.
 
 
                        Dealer (Over-the-Counter) Options
 
   The Fund may engage in transactions involving dealer options. Certain risks
   are specific to dealer options. While the Fund would look to a clearing
   corporation to exercise exchange-traded options, if the Fund were to purchase
   a dealer option, it would rely on the dealer from whom it purchased the
   option to perform if the option were exercised. Failure by the dealer to do
   so would result in the loss of the premium paid by the Fund as well as loss
   of the expected benefit of the transaction.
 
   Exchange-traded options generally have a continuous liquid market while
   dealer options have none. Consequently, the Fund will generally be able to
   realize the value of a dealer option it has purchased only by exercising it
   or reselling it to the dealer who issued it. Similarly, when the Fund writes
   a dealer option, it generally will be able to close out the option prior to
   its expiration only by entering into a closing purchase transaction with the
   dealer to which the Fund originally wrote the option. While the Fund will
   seek to enter into dealer options only with dealers who will agree to and
   which are expected to be capable of entering into closing transactions with
   the Fund, there can be no assurance that the Fund will be able to liquidate a
   dealer option at a favorable price at any time prior to expiration. Until the
   Fund, as a covered dealer call option writer, is able to effect a closing
   purchase transaction, it will not be able to liquidate securities (or other
   assets) or currencies used as cover until the option expires or is exercised.
   In the event of insolvency of the contra party, the Fund may be unable to
   liquidate a dealer option. With respect to options written by the Fund, the
   inability to enter into a closing transaction may result in material losses
   to the Fund. For example, since the Fund must maintain a secured position
   with respect to any call option on a security it writes, the Fund may not
   sell the assets which it has segregated to secure the position while it is
   obligated under the option. This requirement may impair a Fund's ability to
   sell portfolio securities or currencies at a time when such sale might be
   advantageous.
 
   
   The Staff of the SEC has taken the position that purchased dealer options and
   the assets used to secure the written dealer options are illiquid securities.
   The Fund may treat the cover used for written Over-the-Counter ("OTC")
   options as liquid if the dealer agrees that the Fund may repurchase the OTC
   option it has written    
 
 
<PAGE>
 
   
   for a maximum price to be calculated by a predetermined formula. In such
   cases, the OTC option would be considered illiquid only to the extent the
   maximum repurchase price under the formula exceeds the intrinsic value of the
   option.    
 
   Intermediate and Income Funds
 
   The Funds have no current intention of investing in options on securities,
   although they reserve the right to do so. Appropriate disclosure would be
   added to the Funds' prospectus and Statement of Additional Information when
   and if the Funds decide to invest in options.
 
 
                           Interest Rate Transactions
 
   Limited-Term Bond and GNMA Funds
 
   The Funds may enter into various interest rate transactions such as interest
   rate swaps and the purchase or sale of interest rate caps and floors, to
   preserve a return or spread on a particular investment or portion of its
   portfolio, to create synthetic securities, or to structure transactions
   designed for other non-speculative purposes.
 
   Interest rate swaps involve the exchange by the Funds with third parties of
   its respective commitments to pay or receive interest, e.g., an exchange of
   floating rate payments for fixed rate payments. The purchase of an interest
   rate cap entitles the purchaser, to the extent that a specified index exceeds
   a predetermined interest rate, to receive payments of interest on a
   contractually based principal amount from the party selling the interest rate
   cap. The purchase of an interest rate floor entitles the purchaser, to the
   extent that a specified index falls below a predetermined interest rate, to
   receive payments of interest on a contractually based principal amount from
   the party selling the interest rate floor. In circumstances in which T. Rowe
   Price anticipates that interest rates will decline, the Funds might, for
   example, enter into an interest rate swap as the floating rate payor. In the
   case where the Funds purchase such an interest rate swap, if the floating
   rate payments fell below the level of the fixed rate payment set in the swap
   agreement, the Funds counterparties would pay the Funds' amounts equal to
   interest computed at the difference between the fixed and floating rates over
   the national principal amount. Such payments would offset or partially offset
   the decrease in the payments the Funds would receive in respect of floating
   rate assets being hedged. In the case of purchasing an interest rate floor,
   if interest rates declined below the floor rate, the Funds would receive
   payments from the counterparties which would wholly or partially offset the
   decrease in the payments they would receive in respect of the financial
   instruments being hedged.
 
   The Funds will usually enter into interest rate swaps on a net basis, i.e.,
   the two payment streams are netted out, with the Funds receiving or paying,
   as the case may be, only the net amount of the two payments. The net amount
   of the excess, if any, of the Funds' obligations over its entitlements with
   respect to each interest rate swap will be accrued on a daily basis and an
   amount of cash or high-quality liquid securities having an aggregate net
   asset value at least equal to the accrued excess will be maintained in an
   account by the Funds' custodian. If the Funds enter into an interest rate
   swap on other than a net basis, the Funds would maintain an account in the
   full amount accrued on a daily basis of the Funds' obligations with respect
   to the swap. To the extent the Funds sells (i.e., writes) caps and floors, it
   will maintain in an account cash or high-quality liquid debt securities
   having an aggregate net asset value at least equal to the full amount,
   accrued on a daily basis, of the Funds' obligations with respect to any caps
   or floors. The Funds will not enter into any interest rate swap, cap or floor
   transaction unless the unsecured senior debt or the claims paying ability of
   the counterparty thereto is rated at least A by S&P. T. Rowe Price will
   monitor the creditworthiness of counterparties on an ongoing basis. If there
   is a default by the other parties to such a transaction, the Fund will have
   contractual remedies pursuant to the agreements related to the transaction.
 
   The swap market has grown substantially in recent years with a large number
   of banks and investment banking firms acting both as principals and as agents
   utilizing standardized swap documentation. T. Rowe Price has determined that,
   as a result, the swap market has become relative liquid. The Funds may enter
   into interest rate swaps only with respect to positions held in its
   portfolio. Interest rate swaps do not involve the delivery of securities or
   other underlying assets or principal. Accordingly, the risk of loss with
   respect to
 
 
<PAGE>
 
   interest rate swaps is limited to the net amount of interest payments that
   the Funds are contractually obligated to make. If the other parties to
   interest rate swaps default, the Funds' risk of loss consists of the net
   amount of interest payments that the Funds are contractually entitled to
   receive. Since interest rate swaps are individually negotiated, the Funds
   expects to achieve an acceptable degree of correlation between its right to
   receive interest on loan interests and its right and obligation to receive
   and pay interest pursuant to interest rate swaps.
 
   The aggregate purchase price of caps and floor held by the Funds may not
   exceed 10% of the Funds' total assets. The Funds may sell (i.e., write) caps
   and floors without limitation, subject to the account coverage requirement
   described above.

   Transactions in Futures
 
   The Fund may enter into futures contracts including stock index, interest
   rate, and currency futures ("futures" or "futures contracts").
 
   Limited-Term Bond and GNMA Funds
 
   Interest rate or currency futures contracts may be used as a hedge against
   changes in prevailing levels of interest rates or currency exchange rates in
   order to establish more definitely the effective return on securities or
   currencies held or intended to be acquired by the Fund. In this regard, the
   Fund could sell interest rate or currency futures as an offset against the
   effect of expected increases in interest rates or currency exchange rates and
   purchase such futures as an offset against the effect of expected declines in
   interest rates or currency exchange rates.
 
   The Fund will enter into futures contracts which are traded on national or
   foreign futures exchanges, and are standardized as to maturity date and
   underlying financial instrument. Futures exchanges and trading in the United
   States are regulated under the Commodity Exchange Act by the CFTC. Although
   techniques other than the sale and purchase of futures contracts could be
   used for the above-referenced purposes, futures contracts offer an effective
   and relatively low cost means of implementing the Fund's objectives in these
   areas.

   The Fund may enter into futures contracts. Interest rate futures contracts
   may be used as a hedge against changes in prevailing levels of interest rates
   in order to establish more definitely the effective return on securities held

   futures as an offset against the effect of expected increases in interest
   rates and purchase such futures as an offset against the effect of expected
   declines in interest rates. Futures can also be used as an efficient means of
   regulating a Fund's exposure to the market.
 
   The Fund will enter into futures contracts which are traded on national
   futures exchanges and are standardized as to maturity date and underlying
   financial instrument. A public market exists in futures contracts covering
   various taxable fixed income securities as well as municipal bonds. Futures
   exchanges and trading in the United States are regulated under the Commodity
   Exchange Act by the CFTC. Although techniques other than the sale and
   purchase of futures contracts could be used for the above-referenced
   purposes, futures contracts offer an effective and relatively low cost means
   of implementing the Fund's objectives in these areas.
 
   All Funds (other than the Money Funds)
 
   Regulatory Limitations
   If the Fund purchases or sells futures contracts or related options which do
   not qualify as bona fide hedging under applicable CFTC rules, the aggregate
   initial margin deposits and premium required to establish those positions
   cannot exceed 5% of the liquidation value of the Fund after taking into
   account unrealized profits and unrealized losses on any such contracts it has
   entered into; provided, however, that in the case of an
 
 
<PAGE>
 
   option that is in-the-money at the time of purchase, the in-the-money amount
   may be excluded in calculating the 5% limitation. For purposes of this
   policy, options on futures contracts and foreign currency options traded on a
   commodities exchange will be considered "related options." This policy may be
   modified by the Board of Directors without a shareholder vote and does not
   limit the percentage of the Fund's assets at risk to 5%.
 
   In instances involving the purchase of futures contracts or the writing of
   call or put options thereon by the Fund, an amount of cash, liquid assets, or
   other suitable cover as permitted by the SEC, equal to the market value of
   the futures contracts and options thereon (less any related margin deposits),
   will be identified by the Fund to cover the position, or alternative cover
   (such as owning an offsetting position) will be employed. Assets used as
   cover or held in an identified account cannot be sold while the position in
   the corresponding option or future is open, unless they are replaced with
   similar assets. As a result, the commitment of a large portion of a Fund's
   assets to cover or identified accounts could impede portfolio management or
   the Fund's ability to meet redemption requests or other current obligations.
 
   If the CFTC or other regulatory authorities adopt different (including less
   stringent) or additional restrictions, the Fund would comply with such new
   restrictions.
 
   Trading in Futures Contracts
   A futures contract provides for the future sale by one party and purchase by
   another party of a specified amount of a specific financial instrument (e.g.,
   units of a stock index) for a specified price, date, time and place
   designated at the time the contract is made. Brokerage fees are incurred when
   a futures contract is bought or sold and margin deposits must be maintained.
   Entering into a contract to buy is commonly referred to as buying or
   purchasing a contract or holding a long position. Entering into a contract to
   sell is commonly referred to as selling a contract or holding a short
   position.
 
   Unlike when the Fund purchases or sells a security, no price would be paid or
   received by the Fund upon the purchase or sale of a futures contract. Upon
   entering into a futures contract, and to maintain the Fund's open positions
   in futures contracts, the Fund would be required to deposit with its
   custodian in a segregated account in the name of the futures broker an amount
   of cash, or liquid assets known as "initial margin." The margin required for
   a particular futures contract is set by the exchange on which the contract is
   traded, and may be significantly modified from time to time by the exchange
   during the term of the contract. Futures contracts are customarily purchased
   and sold on margins that may range upward from less than 5% of the value of
   the contract being traded.
 
   If the price of an open futures contract changes (by increase in the case of
   a sale or by decrease in the case of a purchase) so that the loss on the
   futures contract reaches a point at which the margin on deposit does not
   satisfy margin requirements, the broker will require an increase in the
   margin. However, if the value of a position increases because of favorable
   price changes in the futures contract so that the margin deposit exceeds the
   required margin, the broker will pay the excess to the Fund.
 
   These subsequent payments, called "variation margin," to and from the futures
   broker, are made on a daily basis as the price of the underlying assets
   fluctuate, making the long and short positions in the futures contract more
   or less valuable, a process known as "marking to market."
 
   Although certain futures contracts, by their terms, require actual future
   delivery of and payment for the underlying instruments, in practice most
   futures contracts are usually closed out before the delivery date. Closing
   out an open futures contract purchase or sale is effected by entering into an
   offsetting futures contract sale or purchase, respectively, for the same
   aggregate amount of the identical securities and the same delivery date. If
   the offsetting purchase price is less than the original sale price, the Fund
   realizes a gain; if it is more, the Fund realizes a loss. Conversely, if the
   offsetting sale price is more than the original purchase price, the Fund
   realizes a gain; if it is less, the Fund realizes a loss. The transaction
   costs must also be included in these calculations. There can be no assurance,
   however, that the Fund will be able to enter into an offsetting transaction
   with respect to a particular futures contract at a particular time. If the
   Fund is not able to enter into an offsetting transaction, the Fund will
   continue to be required to maintain the margin deposits on the futures
   contract.
 
 
<PAGE>
 
   As an example of an offsetting transaction in which the underlying instrument
   is not delivered, the contractual obligations arising from the sale of one
   contract of September Treasury bills on an exchange may be fulfilled at any
   time before delivery of the contract is required (i.e., on a specified date
   in September, the "delivery month") by the purchase of one contract of
   September Treasury bills on the same exchange. In such instance, the
   difference between the price at which the futures contract was sold and the
   price paid for the offsetting purchase, after allowance for transaction
   costs, represents the profit or loss to the Fund.
 
   Intermediate and Income Funds
 
   It is possible that the Fund's hedging activities will occur primarily
   through the use of municipal bond index futures contracts since the
   uniqueness of that index contract should better correlate with the Fund's
   portfolio and thereby be more effective. However, there may be times when it
   is deemed in the best interest of shareholders to engage in the use of
   Treasury bond futures, and the Fund reserves the right to use Treasury bond
   futures at any time. Use of these futures could occur, as an example, when
   both the Treasury bond contract and municipal bond index futures contract are
   correlating well with municipal bond prices, but the Treasury bond contract
   is trading at a more advantageous price making the hedge less expensive with
   the Treasury bond contract than would be obtained with the municipal bond
   index futures contract. The Fund's activity in futures contracts generally
   will be limited to municipal bond index futures contracts and Treasury bond
   and note contracts.

               Special Risks of Transactions in Futures Contracts
 
  . Volatility and Leverage The prices of futures contracts are volatile and are
   influenced, among other things, by actual and anticipated changes in the
   market and interest rates, which in turn are affected by fiscal and monetary
   policies and national and international political and economic events.
 
   Most United States futures exchanges limit the amount of fluctuation
   permitted in futures contract prices during a single trading day. The daily
   limit establishes the maximum amount that the price of a futures contract may
   vary either up or down from the previous day's settlement price at the end of
   a trading session. Once the daily limit has been reached in a particular type
   of futures contract, no trades may be made on that day at a price beyond that
   limit. The daily limit governs only price movement during a particular
   trading day and therefore does not limit potential losses, because the limit
   may prevent the liquidation of unfavorable positions. Futures contract prices
   have occasionally moved to the daily limit for several consecutive trading
   days with little or no trading, thereby preventing prompt liquidation of
   futures positions and subjecting some futures traders to substantial losses.
 
   Margin deposits required on futures trading are low. As a result, a
   relatively small price movement in a futures contract may result in immediate
   and substantial loss, as well as gain, to the investor. For example, if at
   the time of purchase, 10% of the value of the futures contract is deposited
   as margin, a subsequent 10% decrease in the value of the futures contract
   would result in a total loss of the margin deposit, before any deduction for
   the transaction costs, if the account were then closed out. A 15% decrease
   would result in a loss equal to 150% of the original margin deposit, if the
   contract were closed out. Thus, a purchase or sale of a futures contract may
   result in losses in excess of the amount invested in the futures contract.
 
  . Liquidity The Fund may elect to close some or all of its futures positions
   at any time prior to their expiration. The Fund would do so to reduce
   exposure represented by long futures positions or short futures positions.
   The Fund may close its positions by taking opposite positions which would
   operate to terminate the Fund's position in the futures contracts. Final
   determinations of variation margin would then be made, additional cash would
   be required to be paid by or released to the Fund, and the Fund would realize
   a loss or a gain.
 
   Futures contracts may be closed out only on the exchange or board of trade
   where the contracts were initially traded. Although the Fund intends to
   purchase or sell futures contracts only on exchanges or boards of trade where
   there appears to be an active market, there is no assurance that a liquid
   market on an exchange or board of trade will exist for any particular
   contract at any particular time. In such event, it might not be possible to
   close a futures contract, and in the event of adverse price movements, the
   Fund would continue to
 
 
<PAGE>
 
   be required to make daily cash payments of variation margin. However, in the
   event futures contracts have been used to hedge the underlying instruments,
   the Fund would continue to hold the underlying instruments subject to the
   hedge until the futures contracts could be terminated. In such circumstances,
   an increase in the price of underlying instruments, if any, might partially
   or completely offset losses on the futures contract. However, as described
   next, there is no guarantee that the price of the underlying instruments
   will, in fact, correlate with the price movements in the futures contract and
   thus provide an offset to losses on a futures contract.
 
  . Hedging Risk A decision of whether, when, and how to hedge involves skill
   and judgment, and even a well-conceived hedge may be unsuccessful to some
   degree because of unexpected market behavior, market or interest rate trends.
   There are several risks in connection with the use by the Fund of futures
   contracts as a hedging device. One risk arises because of the imperfect
   correlation between movements in the prices of the futures contracts and
   movements in the prices of the underlying instruments which are the subject
   of the hedge. T. Rowe Price will, however, attempt to reduce this risk by
   entering into futures contracts whose movements, in its judgment, will have a
   significant correlation with movements in the prices of the Fund's underlying
   instruments sought to be hedged.
 
   Successful use of futures contracts by the Fund for hedging purposes is also
   subject to T. Rowe Price's ability to correctly predict movements in the
   direction of the market. It is possible that, when the Fund has sold futures
   to hedge its portfolio against a decline in the market, the index, indices,
   or instruments underlying futures might advance and the value of the
   underlying instruments held in the Fund's portfolio might decline. If this
   were to occur, the Fund would lose money on the futures and also would
   experience a decline in value in its underlying instruments. However, while
   this might occur to a certain degree, T. Rowe Price believes that over time
   the value of the Fund's portfolio will tend to move in the same direction as
   the market indices used to hedge the portfolio. It is also possible that, if
   the Fund were to hedge against the possibility of a decline in the market
   (adversely affecting the underlying instruments held in its portfolio) and
   prices instead increased, the Fund would lose part or all of the benefit of
   increased value of those underlying instruments that it has hedged, because
   it would have offsetting losses in its futures positions. In addition, in
   such situations, if the Fund had insufficient cash, it might have to sell
   underlying instruments to meet daily variation margin requirements. Such
   sales of underlying instruments might be, but would not necessarily be, at
   increased prices (which would reflect the rising market). The Fund might have
   to sell underlying instruments at a time when it would be disadvantageous to
   do so.
 
   In addition to the possibility that there might be an imperfect correlation,
   or no correlation at all, between price movements in the futures contracts
   and the portion of the portfolio being hedged, the price movements of futures
   contracts might not correlate perfectly with price movements in the
   underlying instruments due to certain market distortions. First, all
   participants in the futures market are subject to margin deposit and
   maintenance requirements. Rather than meeting additional margin deposit
   requirements, investors might close futures contracts through offsetting
   transactions, which could distort the normal relationship between the
   underlying instruments and futures markets. Second, the margin requirements
   in the futures market are less onerous than margin requirements in the
   securities markets and, as a result, the futures market might attract more
   speculators than the securities markets do. Increased participation by
   speculators in the futures market might also cause temporary price
   distortions. Due to the possibility of price distortion in the futures market
   and also because of imperfect correlation between price movements in the
   underlying instruments and movements in the prices of futures contracts, even
   a correct forecast of general market trends by T. Rowe Price might not result
   in a successful hedging transaction over a very short time period.
 
   Limited-Term Bond and GNMA Funds
 
 
                          Options on Futures Contracts
 
   The Fund may purchase and sell options on the same types of futures in which
   it may invest.
 
   Options (another type of potentially high-risk derivative) on futures are
   similar to options on underlying instruments except that options on futures
   give the purchaser the right, in return for the premium paid, to assume a
   position in a futures contract (a long position if the option is a call and a
   short position if the option
 
 
<PAGE>
 
   is a put), rather than to purchase or sell the futures contract, at a
   specified exercise price at any time during the period of the option. Upon
   exercise of the option, the delivery of the futures position by the writer of
   the option to the holder of the option will be accompanied by the delivery of
   the accumulated balance in the writer's futures margin account which
   represents the amount by which the market price of the futures contract, at
   exercise, exceeds (in the case of a call) or is less than (in the case of a
   put) the exercise price of the option on the futures contract. Purchasers of
   options who fail to exercise their options prior to the exercise date suffer
   a loss of the premium paid.
 
   As an alternative to writing or purchasing call and put options on stock
   index futures, the Fund may write or purchase call and put options on
   financial indices. Such options would be used in a manner similar to the use
   of options on futures contracts. From time to time, a single order to
   purchase or sell futures contracts (or options thereon) may be made on behalf
   of the Fund and other T. Rowe Price Funds. Such aggregated orders would be
   allocated among the Funds and the other T. Rowe Price Funds in a fair and
   nondiscriminatory manner.
 
   Intermediate and Income Funds
 
 
                          Options on Futures Contracts
 
   The Fund might trade in municipal bond index option futures or similar
   options on futures developed in the future. In addition, the Fund may also
   trade in options on futures contracts on U.S. government securities and any
   U.S. government securities futures index contract which might be developed.
   In the opinion of T. Rowe Price, there is a high degree of correlation in the
   interest rate, and price movements of U.S. government securities and
   municipal securities. However, the U.S. government securities market and
   municipal securities markets are independent and may not move in tandem at
   any point in time.
 
   The Fund may purchase put options on futures contracts to hedge its portfolio
   of municipal securities against the risk of rising interest rates, and the
   consequent decline in the prices of the municipal securities it owns. The
   Funds will also write call options on futures contracts as a hedge against a
   modest decline in prices of the municipal securities held in the Fund's
   portfolio. If the futures price at expiration of a written call option is
   below the exercise price, the Fund will retain the full amount of the option
   premium, thereby partially hedging against any decline that may have occurred
   in the Fund's holdings of debt securities. If the futures price when the
   option is exercised is above the exercise price, however, the Fund will incur
   a loss, which may be wholly or partially offset by the increase of the value
   of the securities in the Fund's portfolio which were being hedged.
 
   Writing a put option on a futures contract serves as a partial hedge against
   an increase in the value of securities the Fund intends to acquire. If the
   futures price at expiration of the option is above the exercise price, the
   Fund will retain the full amount of the option premium which provides a
   partial hedge against any increase that may have occurred in the price of the
   debt securities the Fund intends to acquire. If the futures price when the
   option is exercised is below the exercise price, however, the Fund will incur
   a loss, which may be wholly or partially offset by the decrease in the price
   of the securities the Fund intends to acquire.
 
   Options (another type of potentially high-risk derivative) on futures are
   similar to options on underlying instruments except that options on futures
   give the purchaser the right, in return for the premium paid, to assume a
   position in a futures contract (a long position if the option is a call and a
   short position if the option is a put), rather than to purchase or sell the
   futures contract, at a specified exercise price at any time during the period
   of the option. Upon exercise of the option, the delivery of the futures
   position by the writer of the option to the holder of the option will be
   accompanied by the delivery of the accumulated balance in the writer's
   futures margin account which represents the amount by which the market price
   of the futures contract, at exercise, exceeds (in the case of a call) or is
   less than (in the case of a put) the exercise price of the option on the
   futures contract. Purchasers of options who fail to exercise their options
   prior to the exercise date suffer a loss of the premium paid.
 
 
<PAGE>
 
   From time to time a single order to purchase or sell futures contracts (or
   options thereon) may be made on behalf of the Fund and other T. Rowe Price
   Funds. Such aggregated orders would be allocated among the Fund and the other
   T. Rowe Price Funds in a fair and non-discriminatory manner.
 
   All Funds (other than the Money Funds)
 
 
          Special Risks of Transactions in Options on Futures Contracts
 
   
   The risks described under "Special Risks in Transactions on Futures
   Contracts" are substantially the same as the risks of using options on
   futures. If the Fund were to write an option on a futures contract, it would
   be required to deposit and maintain initial and variation margin in the same
   manner as a regular futures contract. In addition, where the Fund seeks to
   close out an option position by writing or buying an offsetting option
   covering the same index, underlying instrument or contract and having the
   same exercise price and expiration date, its ability to establish and close
   out positions on such options will be subject to the maintenance of a liquid
   secondary market. Reasons for the absence of a liquid secondary market on an
   exchange include the following: (1) there may be insufficient trading
   interest in certain options; (2) restrictions may be imposed by an exchange
   on opening transactions or closing transactions or both; (3) trading halts,
   suspensions or other restrictions may be imposed with respect to particular
   classes or series of options, or underlying instruments; (4) unusual or
   unforeseen circumstances may interrupt normal operations on an exchange; (5)
   the facilities of an exchange or a clearing corporation may not at all times
   be adequate to handle current trading volume; or (6) one or more exchanges
   could, for economic or other reasons, decide or be compelled at some future
   date to discontinue the trading of options (or a particular class or series
   of options), in which event the secondary market on that exchange (or in the
   class or series of options) would cease to exist, although outstanding
   options on the exchange that had been issued by a clearing corporation as a
   result of trades on that exchange would continue to be exercisable in
   accordance with their terms. There is no assurance that higher than
   anticipated trading activity or other unforeseen events might not, at times,
   render certain of the facilities of any of the clearing corporations
   inadequate, and thereby result in the institution by an exchange of special
   procedures which may interfere with the timely execution of customers'
   orders.    
 
   In the event no such market exists for a particular contract in which the
   Fund maintains a position, in the case of a written option, the Fund would
   have to wait to sell the underlying securities or futures positions until the
   option expires or is exercised. The Fund would be required to maintain margin
   deposits on payments until the contract is closed. Options on futures are
   treated for accounting purposes in the same way as the analogous option on
   securities are treated.
 
   In addition, the correlation between movements in the price of options on
   futures contracts and movements in the price of the securities hedged can
   only be approximate. This risk is significantly increased when an option on a
   U.S. government securities future or an option on some type of index future
   is used as a proxy for hedging a portfolio consisting of other types of
   securities. Another risk is that the movements in the price of options on
   futures contract and the value of the call increases by more than the
   increase in the value of the securities held as cover, the Fund may realize a
   loss on the call which is not completely offset by the appreciation in the
   price of the securities held as cover and the premium received for writing
   the call.
 
   The successful use of options on futures contracts requires special expertise
   and techniques different from those involved in portfolio securities
   transactions. A decision of whether, when and how to hedge involves skill and
   judgment, and even a well-conceived hedge may be unsuccessful to some degree
   because of unexpected market behavior or interest rate trends. During periods
   when municipal securities market prices are appreciating, the Fund may
   experience poorer overall performance than if it had not entered into any
   options on futures contracts.
 
   General Considerations Transactions by the Fund in options on futures will be
   subject to limitations established by each of the exchanges, boards of trade
   or other trading facilities governing the maximum number of options in each
   class which may be written or purchased by a single investor or group of
   investors acting in concert, regardless of whether the options are written on
   the same or different exchanges, boards of trade or other trading facilities
   or are held or written in one or more accounts or through one or more
 
 
<PAGE>
 
   brokers. Thus, the number of contracts which the Fund may write or purchase
   may be affected by contracts written or purchased by other investment
   advisory clients of T. Rowe Price. An exchange, board of trade or other
   trading facility may order the liquidations of positions found to be in
   excess of these limits, and it may impose certain other sanctions.
 
 
                    Additional Futures and Options Contracts
 
   Although the Fund has no current intention of engaging in futures or options
   transactions other than those described above, it reserves the right to do
   so. Such futures and options trading might involve risks which differ from
   those involved in the futures and options described above.
 
   Limited-Term Bond Fund
 
 
                           Foreign Futures and Options
 
   Participation in foreign futures and foreign options transactions involves
   the execution and clearing of trades on or subject to the rules of a foreign
   board of trade. Neither the National Futures Association nor any domestic
   exchange regulates activities of any foreign boards of trade, including the
   execution, delivery and clearing of transactions, or has the power to compel
   enforcement of the rules of a foreign board of trade or any applicable
   foreign law. This is true even if the exchange is formally linked to a
   domestic market so that a position taken on the market may be liquidated by a
   transaction on another market. Moreover, such laws or regulations will vary
   depending on the foreign country in which the foreign futures or foreign
   options transaction occurs. For these reasons, when the Fund trades foreign
   futures or foreign options contracts, it may not be afforded certain of the
   protective measures provided by the Commodity Exchange Act, the CFTC's
   regulations and the rules of the National Futures Association and any
   domestic exchange, including the right to use reparations proceedings before
   the CFTC and arbitration proceedings provided by the National Futures
   Association or any domestic futures exchange. In particular, funds received
   from the Fund for foreign futures or foreign options transactions may not be
   provided the same protections as funds received in respect of transactions on
   United States futures exchanges. In addition, the price of any foreign
   futures or foreign options contract and, therefore, the potential profit and
   loss thereon may be affected by any variance in the foreign exchange rate
   between the time the Fund's order is placed and the time it is liquidated,
   offset or exercised.
 
 
                          Foreign Currency Transactions
 
   A forward foreign currency exchange contract involves an obligation to
   purchase or sell a specific currency at a future date, which may be any fixed
   number of days from the date of the contract agreed upon by the parties, at a
   price set at the time of the contract. These contracts are principally traded
   in the interbank market conducted directly between currency traders (usually
   large, commercial banks) and their customers. A forward contract generally
   has no deposit requirement, and no commissions are charged at any stage for
   trades.
 
   The Fund may enter into forward contracts for a variety of purposes in
   connection with the management of the foreign securities portion of its
   portfolio. The Fund's use of such contracts would include, but not be limited
   to, the following:
 
   First, when the Fund enters into a contract for the purchase or sale of a
   security denominated in a foreign currency, it may desire to "lock in" the
   U.S. dollar price of the security. By entering into a forward contract for
   the purchase or sale, for a fixed amount of dollars, of the amount of foreign
   currency involved in the underlying security transactions, the Fund will be
   able to protect itself against a possible loss resulting from an adverse
   change in the relationship between the U.S. dollar and the subject foreign
   currency during the period between the date the security is purchased or sold
   and the date on which payment is made or received.
 
   Second, when T. Rowe Price believes that one currency may experience a
   substantial movement against another currency, including the U.S. dollar, it
   may enter into a forward contract to sell or buy the amount of the former
   foreign currency, approximating the value of some or all of the Fund's
   portfolio securities denominated in such foreign currency. Alternatively,
   where appropriate, the Fund may hedge all or part of its foreign currency
   exposure through the use of a basket of currencies or a proxy currency where
   such currency
 
 
<PAGE>
 
   or currencies act as an effective proxy for other currencies. In such a case,
   the Fund may enter into a forward contract where the amount of the foreign
   currency to be sold exceeds the value of the securities denominated in such
   currency. The use of this basket hedging technique may be more efficient and
   economical than entering into separate forward contracts for each currency
   held in the Fund. The precise matching of the forward contract amounts and
   the value of the securities involved will not generally be possible since the
   future value of such securities in foreign currencies will change as a
   consequence of market movements in the value of those securities between the
   date the forward contract is entered into and the date it matures. The
   projection of short-term currency market movement is extremely difficult, and
   the successful execution of a short-term hedging strategy is highly
   uncertain. Under normal circumstances, consideration of the prospect for
   currency parties will be incorporated into the longer term investment
   decisions made with regard to overall diversification strategies. However, T.
   Rowe Price believes that it is important to have the flexibility to enter
   into such forward contracts when it determines that the best interests of the
   Fund will be served.
 
   Third, the Fund may use forward contracts when the Fund wishes to hedge out
   of the dollar into a foreign currency in order to create a synthetic bond or
   money market instrument-the security would be issued in U.S. dollars but the
   dollar component would be transformed into a foreign currency through a
   forward contract.
 
   The Fund may enter into forward contacts for any other purpose consistent
   with the Fund's investment objective and program. However, the Fund will not
   enter into a forward contract, or maintain exposure to any such contract(s),
   if the amount of foreign currency required to be delivered thereunder would
   exceed the Fund's holdings of liquid, high-grade debt securities, currency
   available for cover of the forward contract(s) or other suitable cover as
   permitted by the SEC. In determining the amount to be delivered under a
   contract, the Fund may net offsetting positions.
 
   At the maturity of a forward contract, the Fund may sell the portfolio
   security and make delivery of the foreign currency, or it may retain the
   security and either extend the maturity of the forward contract (by "rolling"
   that contract forward) or may initiate a new forward contract.
 
   If the Fund retains the portfolio security and engages in an offsetting
   transaction, the Fund will incur a gain or a loss (as described below) to the
   extent that there has been movement in forward contract prices. If the Fund
   engages in an offsetting transaction, it may subsequently enter into a new
   forward contract to sell the foreign currency. Should forward prices decline
   during the period between the Fund's entering into a forward contract for the
   sale of a foreign currency and the date it enters into an offsetting contract
   for the purchase of the foreign currency, the Fund will realize a gain to the
   extent the price of the currency it has agreed to sell exceeds the price of
   the currency it has agreed to purchase. Should forward prices increase, the
   Fund will suffer a loss to the extent of the price of the currency it has
   agreed to purchase exceeds the price of the currency it has agreed to sell.
 
   The Fund's dealing in forward foreign currency exchange contracts will
   generally be limited to the transactions described above. However, the Fund
   reserves the right to enter into forward foreign currency contracts for
   different purposes and under different circumstances. Of course, the Fund is
   not required to enter into forward contracts with regard to its foreign
   currency-denominated securities and will not do so unless deemed appropriate
   by T. Rowe Price. It also should be realized that this method of hedging
   against a decline in the value of a currency does not eliminate fluctuations
   in the underlying prices of the securities. It simply establishes a rate of
   exchange at a future date. Additionally, although such contracts tend to
   minimize the risk of loss due to a decline in the value of the hedged
   currency, at the same time, they tend to limit any potential gain which might
   result from an increase in the value of that currency.
 
   Although the Fund values its assets daily in terms of U.S. dollars, it does
   not intend to convert its holdings of foreign currencies into U.S. dollars on
   a daily basis. It will do so from time to time, and investors should be aware
   of the costs of currency conversion. Although foreign exchange dealers do not
   charge a fee for conversion, they do realize a profit based on the difference
   (the "spread") between the prices at which they are buying and selling
   various currencies. Thus, a dealer may offer to sell a foreign currency to
   the Fund at one rate, while offering a lesser rate of exchange should the
   Fund desire to resell that currency to the dealer.

    Federal Tax Treatment of Options, Futures Contracts, and Forward Foreign
                               Exchange Contracts
 
   Limited-Term Bond and GNMA Funds
 
   The discussion herein may refer to transactions in which the GNMA Fund does
   not engage. The Fund's prospectus sets forth the types of transactions
   permissible for the Fund.
 
   The Fund may enter into certain options, futures, and forward foreign
   exchange contracts, including options and futures on currencies, which will
   be treated as Section 1256 contracts or straddles.
 
   Transactions that are considered Section 1256 contracts will be considered to
   have been closed at the end of the Fund's fiscal year and any gains or losses
   will be recognized for tax purposes at that time. Such gains or losses from
   the normal closing or settlement of such transactions will be characterized
   as 60% long-term capital gain (taxable at a maximum rate of 20%) or loss and
   40% short-term capital gain or loss regardless of the holding period of the
   instrument (ordinary income or loss for foreign exchange contracts). The Fund
   will be required to distribute net gains on such transactions to shareholders
   even though it may not have closed the transaction and received cash to pay
   such distributions.
 
   Options, futures and forward foreign exchange contracts, including options
   and futures on currencies, which offset a foreign dollar denominated bond or
   currency position may be considered straddles for tax purposes, in which case
   a loss on any position in a straddle will be subject to deferral to the
   extent of unrealized gain in an offsetting position. The holding period of
   the securities or currencies comprising the straddle will be deemed not to
   begin until the straddle is terminated. The holding period of the security
   offsetting an "in-the-money qualified covered call" option on an equity
   security will not include the period of time the option is outstanding.
 
   Losses on written covered calls and purchased puts on securities, excluding
   certain "qualified covered call" options on equity securities, may be
   long-term capital losses, if the security covering the option was held for
   more than 12 months prior to the writing of the option.
 
   In order for the Fund to continue to qualify for federal income tax treatment
   as a regulated investment company, at least 90% of its gross income for a
   taxable year must be derived from qualifying income, i.e., dividends,
   interest, income derived from loans of securities, and gains from the sale of
   securities or currencies. Tax regulations could be issued limiting the extent
   that net gain realized from option, futures or foreign forward exchange
   contracts on currencies is qualifying income for purposes of the 90%
   requirement.
 
   As a result of the "Taxpayer Relief Act of 1997," entering into certain
   options, futures contracts, or forward contracts may result in the
   "constructive sale" of offsetting stocks or debt securities of the Fund.
 
   Intermediate and Income Funds
 
   Although the Fund invests almost exclusively in securities that generate
   income that is exempt from federal income taxes, the Fund may enter into
   certain option, futures, and foreign exchange contracts, including options
   and futures on currencies, which will be treated as Section 1256 contracts or
   straddles that are not exempt from such taxes. Therefore, use of the
   investment techniques described above could result in taxable income to
   shareholders of the Fund.
 
   Transactions which are considered Section 1256 contracts will be considered
   to have been closed at the end of the Fund's fiscal year and any gains or
   losses will be recognized for tax purposes at that time. Gains or losses
   recognized from the normal closing or settlement of such transactions will be
   characterized as 60% long-term capital gain or loss and 40% short-term
   capital gain or loss, without regard to the holding period of the contract.
   The Fund will be required to distribute net gains on such transactions to
   shareholders even though it may not have closed the transaction and received
   cash to pay such distributions.
 
   Options, futures and forward foreign exchange contracts, including options
   and futures on currencies, which offset a foreign dollar denominated bond or
   currency position may be considered straddles for tax purposes, in which case
   a loss on any position in a straddle will be subject to deferral to the
   extent of unrealized gain in an offsetting position. The holding period of
   the securities or currencies comprising the straddle will be deemed not to
   begin until the straddle is terminated. The holding period of the security
   offsetting an "in-the--
 
 
<PAGE>
 
   money qualified covered call" option on an equity security will not include
   the period of time the option is outstanding.
 
   Losses on written covered calls and purchased puts on securities, excluding
   certain "qualified covered call" options on equity securities, may be
   long-term capital losses, if the security covering the option was held for
   more than 12 months prior to the writing of the option.
 
   In order for the Fund to continue to qualify for federal income tax treatment
   as a regulated investment company, at least 90% of its gross income for a
   taxable year must be derived from qualifying income, i.e., dividends,
   interest, income derived from loans of securities, and gains from the sale of
   securities or currencies. Tax regulations could be issued limiting the extent
   that net gain realized from option, futures or foreign forward exchange
   contracts on currencies is qualifying income for purposes of the 90%
   requirement.
 
   As a result of the "Taxpayer Relief Act of 1997," entering into certain
   options, futures contracts, or forward contracts may result in the
   "constructive sale" of offsetting stocks or debt securities of the Fund.

   (4) Loans Make loans, although the Fund may (i) lend portfolio securities and
       participate in an interfund lending program with other Price Funds

       if, as a result, with respect to 75% of the value of its total assets,
       more than 5% of the value of the Fund's total assets would be invested in

   (6) Percent Limit on Share Ownership of Any One Issuer Purchase a security
       if, as a result, with respect to 75% of the value of the Fund's total
       assets, more than 10% of the outstanding voting securities of any issuer
       would be held by the Fund (other than obligations issued or guaranteed by
       the U.S. government, its agencies or instrumentalities);
 
   (7) Real Estate Purchase or sell real estate, including limited partnership

   (8) Senior Securities Issue senior securities except in compliance with the
       1940 Act;

                                      NOTES
 
       The following Notes should be read in connection with the above-described
       fundamental policies. The Notes are not fundamental policies.
 
       With respect to investment restriction (1), the Cash Reserves and the

       currency contracts or hybrid investments to be commodities.
 
       For purposes of investment restriction (3), U.S., state or local
       governments, or related agencies or instrumentalities, are not considered
       an industry. Industries are determined by reference to the
       classifications of industries set forth in the Fund's semiannual and
       annual reports. It is the position of the Staff of the SEC that foreign
       governments are industries for purposes of this restriction.
 
   All Summit Municipal Funds
 
       For purposes of investment restriction (5), the Fund will treat bonds
       which are refunded with escrowed U.S. government securities as U.S.
       government securities.
 
   All Funds
 
 
                               Operating Policies
 
   As a matter of operating policy, the Fund may not:

   (2) Control of Portfolio Companies Invest in companies for the purpose of
       exercising management or control;
 
   (3) Futures Contracts Purchase a futures contract or an option thereon, if,
       with respect to positions in futures or options on futures which do not
       represent bona fide hedging, the aggregate initial margin and premiums on
       such options would exceed 5% of the Fund's net asset value;
 
   (4) Illiquid Securities Purchase illiquid securities if, as a result, more
       than 15% (10% for Cash Reserves and Municipal Money Market Funds) of its

<PAGE>
 
   (5) Investment Companies Purchase securities of open-end or closed-end
       investment companies except (i) in compliance with the 1940 Act; (ii)

       Funds; or (iii) in the case of the Money Funds, only securities of other
       money market funds;
 
   (6) Margin Purchase securities on margin, except (i) for use of short-term
       credit necessary for clearance of purchases of portfolio securities and
       (ii) it may make margin deposits in connection with futures contracts or

       33/1//\\/3/\\% of the Fund's total assets at the time of borrowing or
       investment;
 
   (8) 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%

       programs;
 
   (9) Options, etc. Invest in puts, calls, straddles, spreads, or any
       combination thereof, except to the extent permitted by the prospectus and
       Statement of Additional Information;
 
   (10) Short Sales Effect short sales of securities; or
 
   (11) Warrants Invest in warrants if, as a result thereof, more than 10% (for
       the Summit Income Funds) or 2% (for the Summit Municipal Funds) of the
       value of the net assets of the Fund would be invested in warrants.
 
 
                                      NOTES
 
       With respect to investment restriction (5), the Funds have no current
       intention of purchasing the securities of other investment companies.
       Duplicate fees could result from any such purchases.
 
   All Funds
 
   Notwithstanding anything in the above fundamental and operating restrictions
   to the contrary, the Fund may invest all of its assets in a single investment
   company or a series thereof in connection with a "master-feeder" arrangement.
   Such an investment would be made where the Fund (a "Feeder"), and one or more
   other Funds with the same investment objective and program as the Fund,
   sought to accomplish its investment objective and program by investing all of
   its assets in the shares of another investment company (the "Master"). The
   Master would, in turn, have the same investment objective and program as the
   Fund. The Fund would invest in this manner in an effort to achieve the
   economies of scale associated with having a Master fund make investments in
   portfolio companies on behalf of a number of Feeder funds.

   directors, has been authorized by its respective Board of Directors to
   exercise all powers of the Board to manage the Funds in the intervals between
   meetings of the Board, except the powers prohibited by statute from being

   a group, owned less than 1% of the outstanding shares of the Fund.
 
   As of January 29, 1999, no shareholder beneficially owned more than 5% of the
   outstanding shares of the Fund.
 
 
 
 INVESTMENT MANAGEMENT SERVICES
 -------------------------------------------------------------------------------
   Services
   Under the Management Agreement, T. Rowe Price provides the Fund with
   discretionary investment services. Specifically, T. Rowe Price is 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 is
   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. In addition to these services, T.
   Rowe Price 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 employees to serve as officers,
   directors, and committee members of the Fund without cost to the Fund.
 
   The Management Agreement also provides that T. Rowe Price, 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 Fee
   Each Fund pays T. Rowe Price an annual all-inclusive fee (the "Fee") as
   follows:
<TABLE>

Municipal Money Market                                                   0.45

Municipal Income                                                         0.50
</TABLE>
 
 
   The Fee is paid monthly to T. Rowe Price on the first business day of the
   next succeeding calendar month and is the sum of the Daily Fee accruals for
   each month. The Daily Fee accrual for any particular day is calculated by
   multiplying the fraction of one (1) over the number of calendar days in the
   year by the appropriate Fee and multiplying this product by the net assets of
   the Fund for that day, as 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.
 
 
<PAGE>
 
   The Management Agreement between each Fund and T. Rowe Price provides that T.
   Rowe Price will pay all expenses of each Fund's operations, except interest,
   taxes, brokerage commissions, and other charges incident to the purchase,
   sale or lending of the Fund's portfolio securities, directors' fees and
   expenses (including counsel fees and expenses) and such non-recurring or
   extraordinary expenses that may arise, including the costs of actions, suits
   or proceedings to which the Fund is a party and the expenses the Fund may
   incur as a result of its obligation to provide indemnification to its
   officers, directors and agents. However, the Board of Directors for the Funds
   reserves the right to impose additional fees against shareholder accounts to
   defray expenses which would otherwise be paid by T. Rowe Price under the
   management agreement. The Board does not anticipate levying such charges;
   such a fee, if charged, may be retained by the Fund or paid to T. Rowe Price.
 
   The following chart sets forth the total management fees, if any, paid to T.
   Rowe Price by each Fund during the last three years:

 DISTRIBUTOR FOR THE FUNDS
 -------------------------------------------------------------------------------
   Investment Services, a Maryland corporation formed in 1980 as a wholly owned
   subsidiary of T. Rowe Price, serves as the Fund's distributor. Investment
   Services is registered as a broker-dealer under the Securities Exchange Act
   of 1934 and is a member of the National Association of Securities Dealers,
   Inc. The offering of the Fund's shares is continuous.
 
   Investment Services is located at the same address as the Fund and T. Rowe
   Price-100 East Pratt Street, Baltimore, Maryland 21202.
 
   Investment Services serves as distributor to the Fund pursuant to an
   Underwriting Agreement ("Underwriting Agreement"), which provides that the
   Fund will pay all fees and expenses in connection with: necessary state
   filings; preparing, setting in type, printing, and mailing its prospectuses
   and reports to shareholders; and issuing its shares, including expenses of
   confirming purchase orders.
 
   The Underwriting Agreement provides that Investment Services will pay all
   fees and expenses in connection with: printing and distributing prospectuses
   and reports for use in offering and selling Fund shares; preparing, setting
   in type, printing, and mailing all sales literature and advertising;
   Investment Services' federal and state registrations as a broker-dealer; and
   offering and selling Fund shares, except for those fees and expenses
   specifically assumed by the Fund. Investment Services' expenses are paid by
   T. Rowe Price.
 
   Investment Services acts as the agent of the Fund in connection with the sale
   of its shares in the various states in which Investment Services is qualified
   as a broker-dealer. Under the Underwriting Agreement, Investment Services
   accepts orders for Fund shares at net asset value. No sales charges are paid
   by investors or the Fund.
 
 
 
 CUSTODIAN
 -------------------------------------------------------------------------------
   State Street Bank and Trust Company is the custodian for the Fund's
   securities and cash, but it does not participate in the Fund's investment
   decisions. Portfolio securities purchased in the U.S. are maintained in the
 
 
<PAGE>
 
   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, or any central depository system allowed by federal law. In
   addition, the Summit Municipal Funds are authorized to maintain certain of
   its securities, in particular, variable rate demand note, in uncertificated
   form, in the proprietary deposit systems of various dealers in municipal
   securities. State Street Bank and the Limited-Term 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 by the Fund's Board of Directors in
   accordance with regulations under the 1940 Act. The 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.
 
   All Funds
 
 
 SHAREHOLDER SERVICES
 -------------------------------------------------------------------------------
   
   T. Rowe Price Services, Inc., another wholly owned subsidiary, acts as the
   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
   and both subsidiaries are paid fees for their 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 of their execution.
   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; 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.
 
 
 
 PORTFOLIO TRANSACTIONS
 -------------------------------------------------------------------------------
   Investment or Brokerage Discretion
   Decisions with respect to the purchase and sale of portfolio securities on
   behalf of the Fund are made by T. Rowe Price. T. Rowe Price is also
   responsible for implementing these decisions, including the negotiation of
   commissions and the allocation of portfolio brokerage and principal business.
   The Fund's purchases and sales of fixed income portfolio securities are
   normally done on a principal basis and do not involve the payment of a
   commission although they may involve the designation of selling concessions.
   That part of the discussion below relating solely to brokerage commissions
   would not normally apply to the Fund. However, it is included because T. Rowe
   Price does manage a significant number of common stock portfolios which do
 
 
<PAGE>
 
   engage in agency transactions and pay commissions and because some research
   and services resulting from the payment of such commissions may benefit the
   Fund.
 
 
                      How Brokers and Dealers Are Selected
 
   Fixed Income Securities
   Fixed income securities are generally purchased from the issuer or a primary
   market-maker acting as principal for the securities on a net basis, with no
   brokerage commission being paid by the client although the price usually
   includes an undisclosed compensation. Transactions placed through dealers
   serving as primary market-makers reflect the spread between the bid and asked
   prices. Securities may also be purchased from underwriters at prices which
   include underwriting fees.
 
   With respect to equity and fixed income securities, T. Rowe Price may effect
   principal transactions on behalf of the Fund with a broker or dealer who
   furnishes brokerage and/or research services, designate any such broker or
   dealer to receive selling concessions, discounts or other allowances, or
   otherwise deal with any such broker or dealer in connection with the
   acquisition of securities in underwritings. T. Rowe Price may receive
   research services in connection with brokerage transactions, including
   designations in a fixed price offerings.
 
 
 How Evaluations Are Made of the Overall Reasonableness of Brokerage Commissions
                                      Paid
 
   On a continuing basis, T. Rowe Price seeks to determine what levels of
   commission rates are reasonable in the marketplace for transactions executed
   on behalf of the Fund. In evaluating the reasonableness of commission rates,
   T. Rowe Price considers: (a) historical commission rates, both before and
   since rates have been fully negotiable; (b) rates which other institutional
   investors are paying, based on available public information; (c) rates quoted
   by brokers and dealers; (d) the size of a particular transaction, in terms of
   the number of shares, dollar amount, and number of clients involved; (e) the
   complexity of a particular transaction in terms of both execution and
   settlement; (f) the level and type of business done with a particular firm
   over a period of time; and (g) the extent to which the broker or dealer has
   capital at risk in the transaction.
 
 
       Descriptions of Research Services Received From Brokers and Dealers
 
   T. Rowe Price receives a wide range of research services from brokers and
   dealers. These services include information on the economy, industries,
   groups of securities, individual companies, statistical information,
   accounting and tax law interpretations, political developments, legal
   developments affecting portfolio securities, technical market action, pricing
   and appraisal services, credit analysis, risk measurement analysis,
   performance analysis and analysis of corporate responsibility issues. These
   services provide both domestic and international perspective. Research
   services are received primarily in the form of written reports, computer
   generated services, telephone contacts and personal meetings with security
   analysts. In addition, such services may be provided in the form of meetings
   arranged with corporate and industry spokespersons, economists, academicians
   and government representatives. In some cases, research services are
   generated by third parties but are provided to T. Rowe Price by or through
   broker-dealers.
 
   Research services received from brokers and dealers are supplemental to T.
   Rowe Price's own research effort and, when utilized, are subject to internal
   analysis before being incorporated by T. Rowe Price into its investment
   process. As a practical matter, it would not be possible for T. Rowe Price's
   Equity Research Division to generate all of the information presently
   provided by brokers and dealers. T. Rowe Price pays cash for certain research
   services received from external sources. T. Rowe Price also allocates
   brokerage for research services which are available for cash. While receipt
   of research services from brokerage firms has not reduced T. Rowe Price's
   normal research activities, the expenses of T. Rowe Price could be materially
   increased if it attempted to generate such additional information through its
   own staff. To the extent that research services of value are provided by
   brokers or dealers, T. Rowe Price may be relieved of expenses which it might
   otherwise bear.
 
   T. Rowe Price has a policy of not allocating brokerage business in return for
   products or services other than brokerage or research services. In accordance
   with the provisions of Section 28(e) of the Securities Exchange Act of 1934,
   T. Rowe Price may from time to time receive services and products which serve
   both research and non-research functions. In such event, T. Rowe Price makes
   a good faith determination of the anticipated
 
 
<PAGE>
 
   research and non-research use of the product or service and allocates
   brokerage only with respect to the research component.
 
 
              Commissions to Brokers Who Furnish Research Services
 
   Certain brokers and dealers who provide quality brokerage and execution
   services also furnish research services to T. Rowe Price. With regard to the
   payment of brokerage commissions, T. Rowe Price has adopted a brokerage
   allocation policy embodying the concepts of Section 28(e) of the Securities
   Exchange Act of 1934, which permits an investment adviser to cause an account
   to pay commission rates in excess of those another broker or dealer would
   have charged for effecting the same transaction, if the adviser determines in
   good faith that the commission paid is reasonable in relation to the value of
   the brokerage and research services provided. The determination may be viewed
   in terms of either the particular transaction involved or the overall
   responsibilities of the adviser with respect to the accounts over which it
   exercises investment discretion. Accordingly, while T. Rowe Price cannot
   readily determine the extent to which commission rates or net prices charged
   by broker-dealers reflect the value of their research services, T. Rowe Price
   would expect to assess the reasonableness of commissions in light of the
   total brokerage and research services provided by each particular broker. T.
   Rowe Price may receive research, as defined in Section 28(e), in connection
   with selling concessions and designations in fixed price offerings in which
   the Funds participate.
 
 
                         Internal Allocation Procedures
 
   T. Rowe Price has a policy of not precommitting a specific amount of business
   to any broker or dealer over any specific time period. Historically, the
   majority of brokerage placement has been determined by the needs of a
   specific transaction such as market-making, availability of a buyer or seller
   of a particular security, or specialized execution skills. However, T. Rowe
   Price does have an internal brokerage allocation procedure for that portion
   of its discretionary client brokerage business where special needs do not
   exist, or where the business may be allocated among several brokers or
   dealers which are able to meet the needs of the transaction.
 
   Each year, T. Rowe Price assesses the contribution of the brokerage and
   research services provided by brokers or dealers, and attempts to allocate a
   portion of its brokerage business in response to these assessments. Research
   analysts, counselors, various investment committees, and the Trading
   Department each seek to evaluate the brokerage and research services they
   receive from brokers or dealers and make judgments as to the level of
   business which would recognize such services. In addition, brokers or dealers
   sometimes suggest a level of business they would like to receive in return
   for the various brokerage and research services they provide. Actual
   brokerage received by any firm may be less than the suggested allocations but
   can, and often does, exceed the suggestions, because the total business is
   allocated on the basis of all the considerations described above. In no case
   is a broker or dealer excluded from receiving business from T. Rowe Price
   because it has not been identified as providing research services.
 
 
                                  Miscellaneous
 
   T. Rowe Price's brokerage allocation policy is consistently applied to all
   its fully discretionary accounts, which represent a substantial majority of
   all assets under management. Research services furnished by brokers or
   dealers through which T. Rowe Price effects securities transactions may be
   used in servicing all accounts (including non-Fund accounts) managed by T.
   Rowe Price. Conversely, research services received from brokers or dealers
   which execute transactions for the Fund are not necessarily used by T. Rowe
   Price exclusively in connection with the management of the Fund.
 
   From time to time, orders for clients may be placed through a computerized
   transaction network.
 
   The Fund does not allocate business to any broker-dealer on the basis of its
   sales of the Fund's shares. However, this does not mean that broker-dealers
   who purchase Fund shares for their clients will not receive business from the
   Fund.
 
   Some of T. Rowe Price's other clients have investment objectives and programs
   similar to those of the Fund. T. Rowe Price may occasionally make
   recommendations to other clients which result in their purchasing or selling
   securities simultaneously with the Fund. As a result, the demand for
   securities being purchased or the
 
 
<PAGE>
 
   supply of securities being sold may increase, and this could have an adverse
   effect on the price of those securities. It is T. Rowe Price's policy not to
   favor one client over another in making recommendations or in placing orders.
   T. Rowe Price frequently follows the practice of grouping orders of various
   clients for execution which generally results in lower commission rates being
   attained. In certain cases, where the aggregate order is executed in a series
   of transactions at various prices on a given day, each participating client's
   proportionate share of such order reflects the average price paid or received
   with respect to the total order. T. Rowe Price has established a general
   investment policy that it will ordinarily not make additional purchases of a
   common stock of a company for its clients (including the T. Rowe Price Funds)
   if, as a result of such purchases, 10% or more of the outstanding common
   stock of such company would be held by its clients in the aggregate.
 
   At the present time, T. Rowe Price does not recapture commissions or
   underwriting discounts or selling group concessions in connection with
   taxable securities acquired in underwritten offerings. T. Rowe Price does,
   however, attempt to negotiate elimination of all or a portion of the
   selling-group concession or underwriting discount when purchasing tax-exempt
   municipal securities on behalf of its clients in underwritten offerings.
 
   Limited-Term Bond Fund
 
 
                  Transactions With Related Brokers and Dealers
 
   
   As provided in the Investment Management Agreement between the Fund and T.
   Rowe Price, T. Rowe Price is responsible not only for making decisions with
   respect to the purchase and sale of the Fund's portfolio securities, but also
   for implementing these decisions, including the negotiation of commissions
   and the allocation of portfolio brokerage and principal business. It is
   expected that T. Rowe Price will often place orders for the Fund's portfolio
   transactions with broker-dealers through the trading desks of certain
   affiliates of Robert Fleming Holdings Limited ("Robert Fleming"), an
   affiliate of Price-Fleming. Robert Fleming, through Copthall Overseas
   Limited, a wholly owned subsidiary, owns 25% of the common stock of
   Price-Fleming. Fifty percent of the common stock of Price-Fleming is owned by
   TRP Finance, Inc., a wholly owned subsidiary of T. Rowe Price, and the
   remaining 25% is owned by Jardine Fleming Holdings Limited, a subsidiary of
   Jardine Fleming Group Limited ("JFG"). JFG is 50% owned by Robert Fleming and
   50% owned by Jardine Matheson Holdings Limited ("Jardine Matheson"). Subject
   to regulatory approvals, Flemings expects to acquire Jardine Matheson's half
   interest in Jardine Fleming during the first half of 1999. Upon completion of
   this transaction, Flemings will own 100% of Jardine Fleming. The affiliates
   through whose trading desks such orders may be placed include Fleming
   Investment Management Limited ("FIM"), and Robert Fleming & Co. Limited
   ("RF&Co."). FIM and RF&Co. are wholly owned subsidiaries of Robert Fleming.
   These trading desks will operate under strict instructions from the Fund's
   portfolio manager with respect to the terms of such transactions. Neither
   Robert Fleming, JFG, nor their affiliates will receive any commission, fee,
   or other remuneration for the use of their trading desks, although orders for
   a Fund's portfolio transactions may be placed with affiliates of Robert
   Fleming and JFG who may receive a commission.    
 
   The Board of Directors of the Fund has authorized T. Rowe Price to utilize
   certain affiliates of Robert Fleming and JFG in the capacity of broker in
   connection with the execution of the Fund's portfolio transactions. Other
   affiliates of Robert Fleming Holding and JFG also may be used. Although it
   does not believe that the Fund's use of these brokers would be subject to
   Section 17(e) of the 1940 Act, the Board of Directors of the Fund has agreed
   that the procedures set forth in Rule 17e-1 under that Act will be followed
   when using such brokers.
 
   The above-referenced authorization was made in accordance with Section 17(e)
   of the 1940 Act and Rule 17e-1 thereunder which require the Funds'
   independent Directors to approve the procedures under which brokerage
   allocation to affiliates is to be made and to monitor such allocations on a
   continuing basis. It is not expected that any portion of the commissions,
   fees, brokerage, or similar payments received by the affiliates of Robert
   Fleming in such transactions will be recaptured by the Funds. The Directors
   have reviewed and from time to time may continue to review whether other
   recapture opportunities are legally permissible and available and, if they
   appear to be, determine whether it would be advisable for a Fund to seek to
   take advantage of them.

 PRICING OF SECURITIES
 -------------------------------------------------------------------------------
   All Funds except Cash Reserves and Municipal Money Market Funds
 
   Fixed income securities are generally traded in the over-the-counter market.
   Investments in securities with remaining maturities of one year or more are
   stated at fair value using a bid-side valuation as furnished by dealers who
   make markets in such securities or by an independent pricing service, which
   considers yield or price of bonds of comparable quality, coupon, maturity,
   and type, as well as prices quoted by dealers who make markets in such
   securities. Investments in mutual funds are valued at the closing net asset
   value per share of the mutual fund on the day of valuation. (For the
   Limited-Term and GNMA Funds) Domestic securities with remaining maturities
   less than one year are stated at fair value which is determined by using a
   matrix system that establishes a value for each security based on bid-side
   money market yields.
 
   There are a number of pricing services available, and the Board of Directors,
   on the basis of an ongoing evaluation of these services, may use or may
   discontinue the use of any pricing service in whole or part.
 
   Securities or other assets for which the above valuation procedures are
   deemed not to reflect fair value will be appraised at prices deemed best to
   reflect their fair value. Such determinations will be made in good faith by
   or under the supervision of officers of each Fund as authorized by the Board
   of Directors.
 
   Limited-Term Bond Fund
 
   For the purposes of determining the Fund's net asset value per share, the
   U.S. dollar value of all assets and liabilities initially expressed in
   foreign currencies is determined by using the mean of the bid and offer
   prices of such currencies against U.S. dollars quoted by a major bank.
 
 
<PAGE>
 
   Cash Reserves and Municipal Money Market Funds
   Securities are valued at amortized cost.
 
 
         Maintenance of Money Fund's Net Asset Value Per Share at $1.00
 
   It is the policy of the Fund to attempt to maintain a net asset value of
   $1.00 per share by using the amortized cost method of valuation permitted by
   Rule 2a-7 under the 1940 Act. Under this method, securities are valued by
   reference to the Fund's acquisition cost as adjusted for amortization of
   premium or accumulation of discount rather than by reference to their market
   value. Under Rule 2a-7:
 
   (a) The Board of Directors must establish written procedures reasonably
       designed, taking into account current market conditions and the Fund's
       investment objectives, to stabilize the Fund's net asset value per share,
       as computed for the purpose of distribution, redemption and repurchase,
       at a single value;
 
   (b) The Fund must (i) maintain a dollar-weighted average portfolio maturity
       appropriate to its objective of maintaining a stable price per share,
       (ii) not purchase any instrument with a remaining maturity greater than
       397 days, and (iii) maintain a dollar-weighted average portfolio maturity
       of 90 days or less;
 
   (c) The Fund must limit its purchase of portfolio instruments, including
       repurchase agreements, to those U.S. dollar-denominated instruments which
       the Fund's Board of Directors determines present minimal credit risks,
       and which are eligible securities as defined by Rule 2a-7; and
 
   (d) The Board of Directors must determine that (i) it is in the best interest
       of the Fund and its shareholders to maintain a stable net asset value per
       share under the amortized cost method; and (ii) the Fund will continue to
       use the amortized cost method only so long as the Board of Directors
       believes that it fairly reflects the market based net asset value per
       share.
 
   Although the Fund believes that it will be able to maintain its net asset
   value at $1.00 per share under most conditions, there can be no absolute
   assurance that it will be able to do so on a continuous basis. If the Fund's
   net asset value per share declined, or was expected to decline, below $1.00
   (rounded to the nearest one cent), the Board of Directors of the Fund might
   temporarily reduce or suspend dividend payments in an effort to maintain the
   net asset value at $1.00 per share. As a result of such reduction or
   suspension of dividends, an investor would receive less income during a given
   period than if such a reduction or suspension had not taken place. Such
   action could result in an investor receiving no dividend for the period
   during which he holds his shares and in his receiving, upon redemption, a
   price per share lower than that which he paid. On the other hand, if the
   Fund's net asset value per share were to increase, or were anticipated to
   increase above $1.00 (rounded to the nearest one cent), the Board of
   Directors of the Fund might supplement dividends in an effort to maintain the
   net asset value at $1.00 per share.
 
 
 
 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
 
 
<PAGE>
 
   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 SEC (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, dividends and 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 Code.    
 
   All Summit Income Funds
 
   A portion of the dividends paid by the Fund may be eligible for the
   dividends-received deduction for corporate shareholders. 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.
 
   All Summit Municipal Funds
 
   Generally, dividends paid by the Funds are not eligible for the
   dividends-received deduction applicable to corporate shareholders. For tax
   purposes, it does not make any difference whether dividends and capital gain
   distributions are paid in cash or in additional shares. Each Fund must
   declare dividends equal to at least 90% of net tax-exempt income (as of its
   year-end) to permit pass-through of tax-exempt income to shareholders, and
   98% of capital gains (as of October 31) in order to avoid a federal excise
   tax, and 100% of capital gains (as of its tax year-end) to avoid federal
   income tax.
 
   All Funds
 
   At the time of your purchase, the Fund's net asset value may reflect
   undistributed capital gains or net unrealized appreciation of securities held
   by the Fund. A subsequent distribution to you of such amounts, although
   constituting a return of your investment, would be taxable as a capital gain
   distribution. 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).
 
 
                        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
 
 
<PAGE>
 
   shareholder is a nonresident alien individual who was physically present in
   the U.S. during the tax year for more than 182 days.
 
   Limited-Term Bond Fund
 
 
                        Foreign Currency Gains and Losses
 
   Foreign currency gains and losses, including the portion of gain or loss on
   the sale of debt securities attributable to foreign exchange rate
   fluctuations, are taxable as ordinary income. If the net effect of these
   transactions is a gain, the ordinary income dividend paid by the Fund will be
   increased. If the result is a loss, the income dividend paid by the Fund will
   be decreased, or to the extent such dividend has already been paid, it may be
   classified as a return of capital. Adjustments to reflect these gains and
   losses will be made at the end of the Fund's taxable year.
 
   To the extent the Limited-Term Bond Fund invests in foreign securities, the
   following would apply:
 
 
                      Passive Foreign Investment Companies
 
   The Fund may purchase the securities of certain foreign investment funds or
   trusts called passive foreign investment companies. Such trusts have been the
   only or primary way to invest in certain countries. In addition to bearing
   their proportionate share of the trust's expenses (management fees and
   operating expenses), shareholders will also indirectly bear similar expenses
   of such trusts. Capital gains on the sale of such holdings are considered
   ordinary income regardless of how long the fund held its investment. In
   addition, the Fund may be subject to corporate income tax and an interest
   charge on certain dividends and capital gains earned from these investments,
   regardless of whether such income and gains are distributed to shareholders.
 
   To avoid such tax and interest, the Fund intends to treat these securities as
   sold on the last day of its fiscal year and recognize any gains for tax
   purposes at that time; deductions for losses are allowable only to the extent
   of any gains resulting from these deemed sales for prior taxable years. Such
   gains and losses will be treated as ordinary income. The Fund will be
   required to distribute any resulting income even though it has not sold the
   security and received cash to pay such distributions.
 
 
 
 YIELD INFORMATION
 -------------------------------------------------------------------------------
   Cash Reserves and Municipal Money Market Funds
   The Fund's current and historical yield for a period is calculated by
   dividing the net change in value of an account (including all dividends
   accrued and dividends reinvested in additional shares) by the account value
   at the beginning of the period to obtain the base period return. This base
   period return is divided by the number of days in the period than multiplied
   by 365 to arrive at the annualized yield for that period. The Fund's
   annualized compound yield for such period is compounded by dividing the base
   period return by the number of days in the period, and compounding that
   figure over 365 days.
 
   Limited-Term Bond, Municipal Intermediate-Term, and Municipal Income Funds
   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 SEC. 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, state, and/or city or local income
   tax rates. 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.
 
 
<PAGE>
 
   GNMA Fund
 
   
   In conformity with regulations of the SEC, an income factor is calculated for
   each security in the portfolio based upon the security's coupon rate. The
   income factors are then adjusted for any gains or losses which have resulted
   from prepayments of principal during the period. The income factors are then
   totalled 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.
   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.

 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 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.

                         Outside Sources of Information
 
   
   From time to time, in reports and promotional literature: (1) the Fund's
   total return performance, ranking, or any other measure of the Fund's
   performance may be compared to any one or combination of the following: (a) a
   broad-based index; (b) other groups of mutual funds, including T. Rowe Price
   Funds, tracked by independent research firms ranking entities, or financial
   publications; (c) indices of securities comparable to those in which the Fund
   invests; (2) the Consumer Price Index (or any other measure for inflation,
   government statistics, such as GNP may be used to illustrate investment
   attributes of the Fund or the general economic, business, investment, or
   financial environment in which the Fund operates; (3) various financial,
   economic and market statistics developed by brokers, dealers and other
   persons may be used to illustrate aspects of the Fund's performance; (4) the
   effect of tax-deferred compounding on the Fund's investment returns, or on
   returns in general in both qualified and nonqualified retirement plans or any
   other tax advantage product, may be illustrated by graphs, charts, etc.; and
   (5) the sectors or industries in which the Fund invests may be compared to
   relevant indices or surveys in order to evaluate the Fund's historical
   performance or current or potential value with respect to the particular
   industry or sector.    
 
 
                               Other Publications
 
   
   From time to time, in newsletters and other publications issued by Investment
   Services, T. Rowe Price mutual fund portfolio managers may discuss economic,
   financial and political developments in the U.S. and abroad and how these
   conditions have affected or may affect securities prices or the Fund;
   individual securities within the Fund's portfolio; and their philosophy
   regarding the selection of individual stocks, including why specific stocks
   have been added, removed or excluded from the Fund's portfolio.    
 
 
                           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 and/or Investment Services 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.
 
 
<PAGE>
 
   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 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 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
 
 
<PAGE>
 
   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 1940 Act.
 
 
 
 FEDERAL REGISTRATION OF SHARES
 -------------------------------------------------------------------------------
   The Fund's shares are registered for sale under the 1933 Act. Registration of
   the Fund's shares is not required under any state law, but the Fund is
   required to make certain filings with and pay fees to the states in order to
   sell its shares in the states.

 RATINGS OF COMMERCIAL PAPER
 -------------------------------------------------------------------------------
   All Summit Income Funds
 
   Moody's Investors Service, Inc. The rating of Prime-1 is the highest
   commercial paper rating assigned by Moody's. Among the factors considered by
   Moody's in assigning rating are the following: valuation of the management of
   the issuer; economic evaluation of the issuer's industry or industries and an
   appraisal of speculative-type risks which may be inherent in certain areas;
   evaluation of the issuer's products in relation to competition and customer
   acceptance; liquidity; amount and quality of long-term debt; trend of
   earnings over a period of 10 years; financial strength of the parent company
   and the relationships which exist with the issuer; and recognition by the
   management of obligations which may be present or may arise as a result of
   public interest questions and preparations to meet such obligations. These
   factors are all considered in determining whether the commercial paper is
   rated P1, P2, or P3.
 
   Standard & Poor's Corporation Commercial paper rated A (highest quality) by
   S&P has the following characteristics: liquidity ratios are adequate to meet
   cash requirements; long-term senior debt is rated "A" or better, although in
   some cases "BBB" credits may be allowed. The issuer has access to at least
   two additional channels of borrowing. Basic earnings and cash flow have an
   upward trend with allowance made for unusual circumstances. Typically, the
   issuer's industry is well established and the issuer has a strong position
   within the industry. The reliability and quality of management are
   unquestioned. The relative strength or weakness of the above factors
   determines whether the issuer's commercial paper is rated A1, A2, or A3.
 
   Fitch IBCA, Inc. Fitch 1-Highest grade Commercial paper assigned this rating
   is regarded as having the strongest degree of assurance for timely payment.
   Fitch 2-Very good grade Issues assigned this rating reflect an assurance of
   timely payment only slightly less in degree than the strongest issues.

   Moody's Investors Services, Inc. P-1 superior capacity for repayment. P-2
   strong capacity for repayment. P-3 acceptable capacity for repayment of
   short-term promissory obligations.
 
   Standard & Poor's Corporation A-1 highest category, degree of safety
   regarding timely payment is strong. Those issues determined to possess
   extremely strong safety characteristics are denoted with a plus sign (+)
   designation. A-2 satisfactory capacity to pay principal and interest. A-3
   adequate capacity for timely payment, but are vulnerable to adverse effects
   of changes in circumstances than higher-rated issues. B and C speculative
   capacity to pay principal and interest.
 
   Fitch IBCA, Inc. F-1+ exceptionally strong credit quality, strongest degree
   of assurance for timely payment. F-1 very strong credit quality. F-2 good
   credit quality, having a satisfactory degree of assurance for timely payment.
   F-3 fair credit quality, assurance for timely payment is adequate but adverse
   changes could cause the securities to be rated below investment grade. F-5
   weak credit quality, having characteristics suggesting a minimal degree of
   assurance for timely payment.

 RATINGS OF CORPORATE DEBT SECURITIES
 -------------------------------------------------------------------------------
 
                        Moody's Investors Services, Inc.
 
   Aaa-Bonds rated Aaa are judged to be of the best quality. They carry the
   smallest degree of investment risk and are generally referred to as "gilt
   edge."
 
   Aa-Bonds rated Aa are judged to be of high quality by all standards. Together
   with the Aaa group they comprise what are generally know as high-grade bonds.
 
   A-Bonds rated A possess many favorable investment attributes and are to be
   considered as upper medium-grade obligations.
 
 
<PAGE>
 
   Baa-Bonds rated Baa are considered as medium-grade obligations, i.e., they
   are neither highly protected nor poorly secured. Interest payments and
   principal security appear adequate for the present but certain protective
   elements may be lacking or may be characteristically unreliable over any
   great length of time. Such bonds lack outstanding investment characteristics
   and in fact have speculative characteristics as well.
 
   Ba-Bonds rated Ba are judged to have speculative elements: their futures
   cannot be considered as well assured. Often the protection of interest and
   principal payments may be very moderate and thereby not well safeguarded
   during both good and bad times over the future. Uncertainty of position
   characterize bonds in this class.
 
   B-Bonds rated B generally lack the characteristics of a desirable investment.
   Assurance of interest and principal payments or of maintenance of other terms
   of the contract over any long period of time may be small.
 
   Caa-Bonds rated Caa are of poor standing. Such issues may be in default or
   there may be present elements of danger with respect to principal or
   interest.
 
   Ca-Bonds rated Ca represent obligations which are speculative in a high
   degree. Such issues are often in default or have other marked short-comings.
 
   C-Bonds rated C represent the lowest-rated, and have extremely poor prospects
   of attaining investment standing.
 
 
                          Standard & Poor's Corporation
 
   AAA-This is the highest rating assigned by Standard & Poor's to a debt
   obligation and indicates an extremely strong capacity to pay principal and
   interest.
 
   AA-Bonds rated AA also qualify as high-quality debt obligations. Capacity to
   pay principal and interest is very strong.
 
   A-Bonds rated A have a strong capacity to pay principal and interest,
   although they are somewhat more susceptible to the adverse effects of changes
   in circumstances and economic conditions.
 
   BBB-Bonds rated BBB are regarded as having an adequate capacity to pay
   principal and interest. Whereas they normally exhibit adequate protection
   parameters, adverse economic conditions or changing circumstances are more
   likely to lead to a weakened capacity to pay principal and interest for bonds
   in this category than for bonds in the A category.
 
   BB, B, CCC, CC, C-Bonds rated BB, B, CCC, and CC are regarded on balance, as
   predominantly speculative with respect to the issuer's capacity to pay
   interest and repay principal. BB indicates the lowest degree of speculation
   and CC the highest degree of speculation. While such bonds will likely have
   some quality and protective characteristics, these are outweighed by large
   uncertainties or major risk exposures to adverse conditions.
 
   D-In default.
 
 
                                Fitch IBCA, Inc.
 
   AAA-High grade, broadly marketable, suitable for investment by trustees and
   fiduciary institutions, and liable to but slight market fluctuation other
   than through changes in the money rate. The prime feature of a "AAA" bond is
   the showing of earnings several times or many times interest requirements for
   such stability of applicable interest that safety is beyond reasonable
   question whenever changes occur in conditions. Other features may enter, such
   as wide margin of protection through collateral, security or direct lien on
   specific property. Sinking funds or voluntary reduction of debt by call or
   purchase or often factors, while guarantee or assumption by parties other
   than the original debtor may influence their rating.
 
   AA-Of safety virtually beyond question and readily salable. Their merits are
   not greatly unlike those of "AAA" class but a bond so rated may be junior
   though of strong lien, or the margin of safety is less strikingly broad.
 
 
<PAGE>
 
   The issue may be the obligation of a small company, strongly secured, but
   influenced as to rating by the lesser financial power of the enterprise and
   more local type of market.
 
   A-Bonds rated A are considered to be investment grade and of high credit
   quality. The obligor's ability to pay interest and repay principal is
   considered to be strong, but may be more vulnerable to adverse changes in
   economic conditions and circumstances than bonds with higher ratings.
 
   BBB-Bonds rated BBB are considered to be investment grade and of satisfactory
   credit quality. The obligor's ability to pay interest and repay principal is
   considered to be adequate. Adverse changes in economic conditions ad
   circumstances, however, are more likely to have adverse impact on these
   bonds, and therefore impair timely payment. The likelihood that the ratings
   of these bonds will fall below investment grade is higher than for bonds with
   higher ratings.
 
   BB, B, CCC, CC, and C are regarded on balance as predominantly speculative
   with respect to the issuer's capacity to repay interest and repay principal
   in accordance with the terms of the obligation for bond issues not in
   default. BB indicates the lowest degree of speculation and C the highest
   degree of speculation. The rating takes into consideration special features
   of the issue, its relationship to other obligations of the issuer, and the
   current and prospective financial condition and operating performance of the
   issuer.
