                              GENERAL INFORMATION

The Trust was established as a Massachusetts business trust under a Declaration
of Trust dated May 8, 1981. The Declaration of Trust permits the Trust to offer
separate series of shares of beneficial interest representing interests in
separate portfolios of securities. The shares in any one portfolio may be
offered in separate classes. As of the date of this prospectus, the Board of
Trustees (the "Trustees") has established two classes of shares of the Trust,
known as Institutional Shares and Institutional Service Shares. This prospectus
relates only to Institutional Shares (the "Shares") of the Trust.

Shares of the Trust are sold primarily to accounts for which financial
institutions act in a fiduciary or agency capacity, or other accounts where the
financial institution maintains master accounts with an aggregate investment of
at least $400 million in certain funds which are advised or distributed by
affiliates of Federated Investors, Inc. An investment in the Trust serves as a
convenient means of accumulating an interest in a professionally managed,
diversified portfolio of municipal securities. A minimum initial investment of
$25,000 over a 90-day period is required. The Trust may not be a suitable
investment for retirement plans since it invests in municipal securities.

Shares are currently sold and redeemed at net asset value without a sales charge
imposed by the Trust.


Year 2000 Statement

Like other mutual funds and business organizations worldwide, the Trust's
service providers (among them, the adviser, distributor, administrator and
transfer agent) must ensure that their computer systems are adjusted to properly
process and calculate date-related information from and after January 1, 2000.
Many software programs and, to a lesser extent, the computer hardware in use
today cannot distinguish the year 2000 from the year 1900. Such a design flaw
could have a negative impact in the handling of securities trades, pricing and
accounting services. The Trust and its service providers are actively working on
necessary changes to computer systems to deal with the year 2000 issue and
believe that systems will be year 2000 compliant when required. Analysis
continues regarding the financial impact of instituting a year 2000 compliant
program on the Trust's operations

                             INVESTMENT INFORMATION

Investment Objective

The investment objective of the Trust is to provide dividend income which is
exempt from federal regular income tax. Interest income of the Trust that is
exempt from federal regular income tax retains its tax-free status when
distributed to the Trust's shareholders. The Trust attempts to achieve its
investment objective by investing at least 80% of its net assets in a
diversified portfolio of municipal securities or by investing its assets so that
at least 80% of its income will be tax-exempt. While there is no assurance that
the Trust will achieve its investment objective, it endeavors to do so by
following the investment policies described in this prospectus. The investment
objective, and the above investment policy, cannot be changed without approval
of shareholders.

Investment Policies

The investment policies described below may be changed by the Trustees without
shareholder approval. Shareholders will be notified before any material change
in these policies becomes effective.

Acceptable Investments
The municipal securities in which the Trust invests are:

 . debt obligations issued by or on behalf of any state, territory, or possession
  of the United States, including the District of Columbia, or any political
  subdivision of any of these, including industrial development bonds, the
  interest from which is, in the opinion of bond counsel for the issuers or in
  the opinion of officers of the Trust and/or the investment adviser to the
  Trust, exempt from federal regular income tax; and

 . participation interests, as described below, in any of the above obligations.

Average Maturity

The dollar-weighted average maturity of the Trust's portfolio of municipal
securities will be less than three years. For purposes of determining the
dollar-weighted average maturity of the Trust's portfolio, the maturity of a
municipal security will be its ultimate maturity, unless it is probable that the
issuer of the security will take advantage of maturity-shortening devices such
as a call, refunding, or redemption provision, in which case the maturity date
will be the date on which it is probable that the security will be called,
refunded, or redeemed. If the municipal security includes the right to demand
payment, the maturity of the security for purposes of determining the Trust's
dollar-weighted average maturity will be the period remaining until the
principal amount of the security can be recovered by exercising the right to
demand payment.

Characteristics
The municipal securities in which the Trust invests are:

 . rated within the four highest ratings for municipal securities by Moody's
  Investors Service, Inc. ("Moody's") (Aaa, Aa, A, or Baa) or by Standard &
  Poor's ("S&P") and Fitch IBCA, Inc. ("Fitch") (AAA, AA, A, or BBB);

 . guaranteed at the time of purchase by the U.S. government as to the payment
  of principal and interest;

 . rated at the time of purchase within the two highest ratings categories of
  Moody's short-term municipal securities ratings, (MIG1/VMIG1, MIG2/VMIG2) or
  Moody's municipal commercial paper ratings, (P-1, P-2) or S&P's municipal note
  rating, (SP-1, SP-2) or S&P's municipal commercial paper and short-term
  ratings, (A-1, A-2); or

 . unrated, if at the time of purchase, determined by the Trust's investment
 adviser to be of comparable quality to municipal securities as stated above.

Changes in economic or other circumstances are more likely to lead to weakened
capacity to make principal and interest payments than higher rated securities.

Downgraded securities will be evaluated on a case-by-case basis by the adviser.
The adviser will determine whether or not the security continues to be an
acceptable investment. If not, the security will be sold. The prices of fixed
income securities fluctuate inversely to the direction of interest rates. A
description of the rating categories is contained in the Appendix to the
Statement of Additional Information.

Participation Interests

The Trust may purchase participation interests from financial institutions such
as commercial banks, savings associations, and insurance companies. These
participation interests give the Trust an undivided interest in municipal
securities. The financial institutions from which the Trust purchases
participation interests frequently provide or secure irrevocable letters of
credit or guarantees to assure that the participation interests are of high
quality. The Trustees will determine that participation interests meet the
prescribed quality standards for the Trust.

Variable Rate Municipal Securities

Some of the municipal securities which the Trust purchases may have variable
interest rates. Variable interest rates are ordinarily based on a published
interest rate or interest rate index or some similar standard, such as the 91-
day U.S. Treasury bill rate. Variable rate municipal securities will be treated
as maturing on the date of the next scheduled

adjustment to the interest rate for purposes of determining the dollar-weighted
average maturity of the portfolio.


Inverse Floaters

The Trust may invest in securities known as "inverse floaters" which represent
interests in municipal securities. The Trust intends to purchase inverse
floaters to assist in pursuing its investment objective. These obligations pay
interest rates that vary inversely with changes in the interest rates of
specified short-term municipal securities or an index of short-term municipal
securities. The interest rates on inverse floaters will typically decline as
short-term market interest rates increase and increase as short-term market
rates decline. Inverse floaters will generally respond to changes in market
interest rates more rapidly than fixed-rate long-term securities (typically
twice as fast). As a result, the market values of inverse floaters will
generally be more volatile than the market values of fixed-rate municipal
securities. Typically, the portion of the portfolio invested in inverse floaters
will be subject to additional volatility.


Financial Futures

The Trust may purchase and sell interest rate and index financial futures
contracts. These financial futures contracts may be used to hedge all or a
portion of its portfolio against changes in the market value of portfolio
securities and interest rates, provide additional liquidity, and accomplish its
current strategies in a more expeditious fashion. Financial futures contracts
call for the delivery of particular debt instruments at a certain time in the
future. The seller of the contract agrees to make delivery of the type of
instrument called for in the contract and the buyer agrees to take delivery of
the instrument at the specified future time.

As a matter of investment policy, which may be changed without shareholder
approval, the Trust may not purchase or sell futures contracts if immediately
thereafter the sum of the amount of margin deposits on the Trust's existing
futures positions would exceed 5% of the market value of the Trust's total
assets. When the Trust purchases futures contracts, an amount of municipal
securities, cash or cash equivalents, equal to the underlying commodity value of
the futures contracts (less any related margin deposits), will be deposited in a
segregated account with the Trust's custodian (or the broker, if legally
permitted) to collateralize the position.


Risks
When the Trust uses financial futures, there is a risk that the prices of the
securities subject to the futures contracts may not correlate perfectly with the
prices of the securities in the Trust's portfolio. This may cause the futures
contract to react differently than the portfolio securities to market changes.
In addition, the Trust's investment adviser could be incorrect in its
expectations about the direction or extent of market factors such as interest
rate movements. In these events, the Trust may lose money on the futures
contract. It is not certain that a secondary market for positions in futures
contracts will exist at all times. Although the investment adviser will consider
liquidity before entering into futures transactions, there is no assurance that
a liquid secondary market on an exchange or otherwise will exist for any
particular futures contract at any particular time. The Trust's ability to
establish and close out futures positions depends on this secondary market.

When-Issued and Delayed Delivery Transactions

The Trust may purchase municipal securities on a when-issued or delayed delivery
basis. These transactions are arrangements in which the Trust purchases
securities with payment and delivery scheduled for a future time. The seller's
failure to complete these transactions may cause the Trust to miss a price or
yield considered to be advantageous. Settlement dates may be a month or more
after entering into these transactions, and the market values of the securities
purchased may vary from the purchase prices. The Trust may dispose of a
commitment prior to settlement if the adviser deems it appropriate to do so. In
addition, the Trust may enter into transactions to sell its purchase commitments
to third parties at current market values and simultaneously acquire other
commitments to purchase similar securities at later dates. The Trust may realize
short-term profits or losses upon the sale of such commitments.


Investing in Securities of Other Investment Companies

The Trust may invest its assets in securities of other investment companies as
an efficient means of carrying out its investment policies. It should be noted
that investment companies incur certain expenses, such as management fees, and,
therefore, any investment by the Trust in shares of other investment companies
may be subject to such duplicate expenses.

Temporary Investments

From time to time on a temporary basis, when the investment adviser determines
that market conditions call for a temporary defensive posture, the Trust may
invest in short-term temporary investments which may or may not be exempt from
federal income tax. Temporary investments include: tax-exempt variable and
floating rate demand notes; tax-free commercial paper; other temporary municipal
securities; obligations issued or guaranteed by the U.S. government, its
agencies or instrumentalities; other debt securities; commercial paper;
certificates of deposit of domestic branches of U.S. banks; and repurchase
agreements (arrangements in which the organization selling the Trust a security
agrees at the time of sale to repurchase it at a mutually agreed upon time and
price).

There are no rating requirements applicable to temporary investments with the
exception of temporary municipal securities which are subject to the same rating
requirements as all other municipal securities in which the Trust invests.
However, the investment adviser will limit temporary investments to those it
considers to be of comparable quality to the acceptable investments of the
Trust.

Although the Trust is permitted to make taxable, temporary investments, there is
no current intention of generating income subject to federal regular income tax.

Municipal Securities

Municipal securities are generally issued to finance public works such as
airports, bridges, highways, housing, hospitals, mass transportation projects,
schools, streets, and water and sewer works. They are also issued to repay
outstanding obligations, to raise funds for general operating expenses, and to
make loans to other public institutions and facilities. Municipal securities
include industrial development bonds issued by or on behalf of public
authorities to provide financing aid to acquire sites or construct and equip
facilities for privately or publicly owned corporations. The availability of
this financing encourages these corporations to locate within the sponsoring
communities and thereby increases local employment. The two principal
classifications of municipal securities are "general obligation" and "revenue"
bonds. General obligation bonds are secured by the issuer's pledge of its full
faith and credit and taxing power for the payment of principal and interest.
Interest on and principal of revenue bonds, however, are payable only from the
revenue generated by the facility financed by the bond or other specified
sources of revenue. Revenue bonds do not represent a pledge of credit or create
any debt of or charge against the general revenues of a municipality or public
authority. Industrial development bonds are typically classified as revenue
bonds.

Investment Risks

Yields on municipal securities depend on a variety of factors, including: the
general conditions of the money market and the taxable and municipal bond
markets; the size of the particular offering; the maturity of the obligations;
and the rating of the issue. The ability of the Trust to achieve its investment
objective also depends on the continuing ability of the issuers of municipal
securities and participation interests, or the guarantors of either, to meet
their obligations for the payment of interest and principal when due.

Investment Limitations
The Trust will not:

 . Invest more than 5% of its total assets in securities of one issuer (except
  cash and cash items and U.S. government obligations); or

 . borrow money or pledge securities except, under certain circumstances, the
  Trust may borrow up to one-third of the value of its total assets and pledge
  up to 10% of the value of those assets to secure such borrowings.

The above investment limitations cannot be changed without shareholder approval.
The following limitations, however, can be changed by the Trustees without
shareholder approval. Shareholders will be notified before any material change
in these limitations becomes effective.

The Trust will not:

 . Commit more than 15% of its net assets to illiquid obligations; or

 .invest more than 5% of its total assets in industrial development bonds of
 issuers that have a record of less than three years of continuous operations.


                               TRUST INFORMATION

Management of the Trust
Board of Trustees

The Trust is managed by a Board of Trustees. The Trustees are responsible for
managing the Trust's business affairs and for exercising all the Trust's powers
except those reserved for the shareholders. The Executive Committee of the Board
of Trustees handles the Board's responsibilities between meetings of the Board.

Investment Adviser

Investment decisions for the Trust are made by Federated Management, the Trust's
investment adviser (the "Adviser"), subject to direction by the Trustees. The
Adviser continually conducts investment research and supervision for the Trust
and is responsible for the purchase or sale of portfolio instruments, for which
it receives an annual fee from the Trust.

 Advisory Fees

 The Trust's Adviser receives an annual investment advisory fee equal to 0.40%
 of the Trust's average daily net assets. Under the investment advisory
 contract, the Adviser will reimburse the Trust the amount, limited to the
 amount of the advisory fee, by which the Trust's aggregate annual operating
 expenses, including its investment advisory fee, but excluding interest, taxes,
 brokerage commissions, expenses of registering and qualifying the Trust and its
 shares under federal and state laws and regulations, expenses of withholding
 taxes, and extraordinary expenses, exceed 0.45% of its average daily net
 assets. This does not include reimbursement to the Trust of any expenses
 incurred by shareholders who use the transfer agent's subaccounting facilities.

Distribution of Institutional Shares

Federated Securities Corp. is the principal distributor for Institutional
Shares. It is a Pennsylvania corporation organized on November 14, 1969, and is
the principal distributor for a number of investment companies. Federated
Securities Corp. is a subsidiary of Federated Investors, Inc.

Administration of the Trust
Administrative Services

Federated Services Company, a subsidiary of Federated Investors, Inc., provides
administrative personnel and services (including certain legal and financial
reporting services) necessary to operate the Trust. Federated Services Company
provides these at an annual rate which relates to the average aggregate daily
net assets of all funds advised by subsidiaries ofFederated Investor, Inc.
("Federated Funds") as specifiedbelow:

  Maximum             Average Aggregate
    Fee               Daily Net Assets
- ---------     ------------------------------------
  0.150%           on the first $250 million

  0.125%           on the next $250 million

  0.100%           on the next $250 million

  0.075%       on assets in excess of $750 million

The administrative fee received during any fiscal year shall be at least
$125,000 per portfolio and $30,000 per each additional class of shares.
Federated Services Company may choose voluntarily to waive a portion of its fee.

Shareholder Services

The Trust has entered into a Shareholder Services Agreement with Federated
Shareholder Services, a subsidiary of Federated Investors, Inc., under which the
Trust may make payments up to 0.25% of the average daily net asset value of its
shares, computed at an annual rate, to obtain certain personal services for
shareholders and to maintain shareholder accounts. From time to time and for
such periods as deemed appropriate, the amount stated above may be reduced
voluntarily. Under the Shareholder Services Agreement, Federated Shareholder
Services will either perform shareholder services directly or will select
financial institutions to perform shareholder services. Financial institutions
will receive fees based upon shares owned by their clients or customers. The
schedules of such fees and the basis upon which fees will be paid will be
determined from time to time by the Trust and Federated Shareholder Services.

Supplemental Payments to Financial Institutions

In addition to payments made pursuant to the Distribution Plan and Shareholder
Services Agreement, Federated Securities Corp. and Federated Shareholder
Services, from their own assets, may pay financial institutions supplemental
fees for the performance of substantial sales services, distribution-related
support services, or shareholder services. The support may include sponsoring
sales, educational and training seminars for their employees, providing sales
literature, and engineering computer software programs that emphasize the
attributes of the Trust. Such assistance will be predicated upon the amount of
shares the financial institution sells or may sell, and/or upon the type and
nature of sales or marketing support furnished by the financial institution. Any
payments made by the distributor may be reimbursed by the Trust's investment
adviser or its affiliates.

                                NET ASSET VALUE

The Trust's net asset value per Share fluctuates. The net asset value for Shares
is determined by adding the interest of the Shares in the market value of all
securities and other assets of the Trust, subtracting the interest of the Shares
in the liabilities of the Trust and those attributable to Shares, and dividing
the remainder by the total number of Shares outstanding. The net asset value for
Shares may differ from that of Institutional Service Shares due to the variance
in daily net income realized by each class. Such variance will reflect only
accrued net income to which the shareholders of a particular class are entitled.

                       INVESTING IN INSTITUTIONAL SHARES

Share Purchases
Shares are sold on days on which the New York Stock Exchange and the Federal
Reserve wire system are open for business. Shares may be purchased either by
wire or by mail.

To purchase Shares, open an account by calling Federated Securities Corp.
Information needed to establish the account will be taken over the telephone.
The Trust reserves the right to reject any purchase request. By Wire To purchase
Shares by Federal Reserve wire, call the Trust before 4:00 p.m. (Eastern time)
to place an order. The order is considered received immediately. Payment by
federal funds must be received before 3:00 p.m. (Eastern time) on the next
business day following the order. Federal funds should be wired as follows:
Federated Shareholder Services Company, c/oState Street Bank and Trust Company,
Boston, Massachusetts; Attention: EDGEWIRE; For Credit to: Federated Short-Term
Municipal Trust--Institutional Shares; Trust Number (this number can be found on
the account statement or by contacting the Trust); Group Number or Wire Order
Number; Nominee or Institution Name; and ABA Number 011000028. Shares cannot be
purchased on days on which the New York Stock Exchange is closed and on federal
holidays restricting wire transfers. Questions on wire purchases should be
directed to your shareholder services representative at the telephone number
listed on your account statement.

By Mail
To purchase Shares by mail, send a check made payable to Federated Short-Term
Municipal Trust--Institutional Shares to: Federated Shareholder Services
Company, P.O. Box 8600, Boston, Massachusetts 02266-8600. Orders by mail are
considered received when payment by check is converted into federal funds. This
is normally the next business day after the check is received.

Minimum Investment Required

The minimum initial investment in Shares is $25,000 plus any financial
intermediary's fee, if applicable. However, an account may be opened with a
smaller amount as long as the $25,000 minimum is reached within 90 days. The
minimum investment for an institutional investor will be calculated by combining
all accounts it maintains with the Trust. Accounts established through a
financial intermediary may be subject to a smaller minimum investment.

What Shares Cost

Shares are sold at their net asset value next determined after an order is
received. There is no sales charge imposed by the Trust. Investors who purchase
Shares through a financial intermediary may be charged a service fee by that
financial intermediary.

The net asset value is determined as of the close of trading (normally 4:00
p.m., Eastern time) on the New York Stock Exchange, Monday through Friday,
except on (i) days on which there are not sufficient changes in the value of the
Trust's portfolio securities that its net asset value might be materially
affected; (ii) days during which no Shares are tendered for redemption and no
orders to purchase Shares are received; or (iii) the following holidays: New
Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial
Day, Independence Day, Labor Day, Thanksgiving Day, and Christmas Day.

Confirmations and Account Statements

Shareholders will receive detailed confirmations of transactions. In addition,
shareholders will receive periodic statements reporting all account activity,
including dividends paid. The Trust will not issue share certificates.

Dividends

Dividends are declared daily and paid monthly. Dividends are declared just prior
to determining net asset value. If an order for Shares is placed on the
preceding business day, Shares purchased by wire begin earning dividends on the
business day wire payment is received by State Street Bank. If the order for
Shares and payment by wire are received on the same day, Shares begin earning
dividends on the next business day. Shares purchased by check begin earning
dividends on the business day after the check is converted, upon instruction of
the transfer agent, into federal funds. Dividends are automatically reinvested
in additional Shares unless cash payments are requested by contacting the Trust.

Capital Gains
Distributions of net realized long-term capital gains realized by the Trust, if
any, will be made at least annually.

                         REDEEMING INSTITUTIONAL SHARES

The Trust redeems Shares at their net asset value next determined after the
Trust receives the redemption request. Investors who redeem Shares through a
financial intermediary may be charged a service fee by that financial
intermediary. Redemptions may be made on days on which the Trust computes its
net asset value. Redemption requests must be received in proper form and can be
made by telephone request or by written request.

Telephone Redemption

Shareholders may redeem their Shares by telephoning the Trust before 4:00 p.m.
(Eastern time). The proceeds will normally be wired the following business day,
but in no event more than seven days, to the shareholder's account at a domestic
commercial bank that is a member of the Federal Reserve System. If at any time
the Trust shall determine it necessary to terminate or modify this method of
redemption, shareholders would be promptly notified.

An authorization form permitting the Trust to accept telephone requests must
first be completed. It is recommended that investors request this privilege at
the time of their initial application. If not completed at the time of initial
application, authorization forms and information on this service can be obtained
through Federated Securities Corp. Telephone redemption instructions may be
recorded. If reasonable procedures are not followed by the Trust, it may be
liable for losses due to unauthorized or fraudulent telephone instructions.

In the event of drastic economic or market changes, a shareholder may experience
difficulty in redeeming by telephone. If such a case should occur, another
method of redemption, such as "Written Requests," should be considered.

Written Requests

Shares may also be redeemed by sending a written request to Federated
Shareholder Services Company, P.O. Box 8600, Boston, Massachusetts 02266-8600.
Call the Trust for specific instructions before redeeming by letter. The
shareholder will be asked to provide in the request his name, the Trust name and
class of shares, his account number, and the Share or dollar amount requested.
If Share certificates have been issued, they should be sent unendorsed with the
written request by registered or certified mail to the address noted above.

Signatures

Shareholders requesting a redemption of any amount to be sent to an address
other than that on record with the Trust, or a redemption payable other than to
the shareholder of record must have their signatures guaranteed by:

 . a trust company or commercial bank whose deposits are insured by the Bank
  Insurance Fund, which is administered by the Federal Deposit Insurance
  Corporation ("FDIC");

 . a member of the New York, American, Boston, Midwest, or Pacific Stock
  Exchange;

 . a savings bank or savings association whose deposits are insured by the
  Savings Association Insurance Fund, which is administered by the FDIC; or

 . any other "eligible guarantor institution" as defined in the Securities
  Exchange Act of 1934, as amended.

The Trust does not accept signatures guaranteed by a notarypublic.

The Trust and its transfer agent have adopted standards for accepting signature
guarantees from the above institutions. The Trust may elect in the future to
limit eligible signature guarantors to institutions that are members of a
signature guarantee program. The Trust and its transfer agent reserve the right
to amend these standards at any time without notice.

Receiving Payment
Normally, a check for the proceeds is mailed within one business day, but in no
event more than seven days, after receipt of a proper written redemption
request.

Accounts with Low Balances

Due to the high cost of maintaining accounts with low balances, the Trust may
redeem Shares in any account and pay the proceeds to the shareholder if the
account balance falls below a required minimum value of $25,000 due to
shareholder redemptions. This requirement does not apply, however, if the
balance falls below $25,000 because of changes in the Trust's net asset value.
Before Shares are redeemed to close an account, the shareholder is notified in
writing and allowed 30 days to purchase additional Shares to meet the minimum
requirement.

                            SHAREHOLDER INFORMATION

Voting Rights

Each Share of the Trust gives the shareholder one vote in Trustee elections and
other matters submitted to shareholders for vote. All shares of all classes of
each portfolio in the Trust have equal voting rights except that in matters
affecting only a particular portfolio or class, only shares of that portfolio or
class are entitled to vote. As a Massachusetts business trust, the Trust is not
required to hold annual shareholder meetings. Shareholder approval will be
sought only for certain changes in the Trust's operation and for the election of
Trustees under certain circumstances.

Trustees may be removed by the Trustees or by shareholders at a special meeting.
A special meeting of shareholders shall be called for this purpose by the
Trustees upon written request of shareholders owning at least 10% of the
outstanding shares of the Trust entitled to vote.

                                TAX INFORMATION

Federal Income Tax

The Trust will pay no federal income tax because it expects to meet requirements
of the Internal Revenue Code of 1986, as amended, applicable to regulated
investment companies and to receive the special tax treatment afforded to such
companies.

Shareholders are not required to pay the federal regular income tax on any
dividends received from the Trust that represent net interest on tax-exempt
municipal bonds. However, dividends representing net interest earned on some
municipal bonds may be included in calculating the federal individual
alternative minimum tax or the federal alternative minimum tax for corporations.

The alternative minimum tax, equal to up to 28% of alternative minimum taxable
income for individuals and 20% for corporations, applies when it exceeds the
regular tax for the taxable year. Alternative minimum taxable income is equal to
the regular taxable income of the taxpayer increased by certain "tax preference"
items not included in regular taxable income and reduced by only a portion of
the deductions allowed in the calculation of the regular tax.

Interest on certain "private activity" bonds issued after August 7, 1986, is
treated as a tax preference item for both individuals and corporations. Unlike
traditional governmental purpose municipal bonds, which finance roads, schools,
libraries, prisons and other public facilities, private activity bonds provide
benefits to private parties. The Trust may purchase all types of municipal
bonds, including private activity bonds. Thus, while the Trust has no present
intention of purchasing any private activity bonds, should it purchase any such
bonds, a portion of the Trust's dividends may be treated as a tax preference
item.

In addition, in the case of a corporate shareholder, dividends of the Trust
which represent interest on municipal bonds may be subject to the 20% corporate
alternative minimum tax because the dividends are included in a corporation's
"adjusted current earnings." The corporate alternative minimum tax treats 75% of
the excess of a taxpayer's pre-tax "adjusted current earnings" over the
taxpayer's alternative minimum taxable income as a tax preference item.
"Adjusted current earnings" is based upon the concept of a corporation's
"earnings and profits." Since "earnings and profits" generally includes the full
amount of any Trust dividend, and alternative minimum taxable income does not
include the portion of the Trust's dividend attributable to municipal bonds
which are not private activity bonds, the difference will be included in the
calculation of the corporation's alternative minimum tax.

Dividends of the Trust representing net interest income earned on some temporary
investments and any realized net short-term gains are taxed as ordinary income.

These tax consequences apply whether dividends are received in cash or as
additional Shares. Information on the tax status of dividends and distributions
is provided annually.

State and Local Taxes

Because interest received by the Trust may not be exempt from all state and
local income taxes, shareholders may be required to pay state and local taxes on
dividends received from the Trust. Shareholders are urged to consult their own
tax advisers regarding the status of their accounts under state and local tax
laws.

                            PERFORMANCE INFORMATION

From time to time the Trust advertises its total return, yield, and tax-
equivalent yield for Institutional Shares.

Total return represents the change, over a specific period of time, in the value
of an investment in Shares of the Trust after reinvesting all income and capital
gain distributions. It is calculated by dividing that change by the initial
investment and is expressed as a percentage.

The yield of Shares of the Trust is calculated by dividing the net investment
income per share (as defined by the Securities and Exchange Commission) earned
by Shares over a thirty-day period by the maximum offering price per share of
Shares on the last day of the period. This number is then annualized using
semi-annual compounding. The tax-equivalent yield of Shares is calculated
similarly to the yield, but is adjusted to reflect the taxable yield that Shares
would have had to earn to equal its actual yield, assuming a specific tax rate.
The yield and the tax-equivalent yield do not necessarily reflect income
actually earned by Shares and, therefore, may not correlate to the dividends or
other distributions paid to shareholders.

The Trust is sold without any sales charge or other similar non-recurring
charges.

Total return, yield, and tax-equivalent yield will be calculated separately for
Shares and Institutional Service Shares.

From time to time, advertisements for the Trust may refer to ratings, rankings
and other information in certain financial publications and/or compare the
Trust's performance to certain indices.

                            OTHER CLASSES OF SHARES

The Trust also offers another class of shares called Institutional Service
Shares.

Institutional Service Shares are sold primarily to retail and private banking
customers of financial institutions at net assetvalue and are subject to a
minimum initial investment of$25,000.

Institutional Shares and Institutional Service Shares are subject to certain of
the same expenses; however, Institutional Service Shares are distributed
pursuant to a 12b-1 Plan adopted by the Trust whereby the distributor is paid a
fee of up to 0.25% of the Institutional Service Shares' average daily net
assets.

Expense differences between Institutional Shares and Institutional Service
Shares may affect the performace of eachclass.

Financial institutions and brokers providing sales and/or administrative
services may receive different compensation depending upon which class of shares
of the Trust is sold.

The stated advisory fee is the same for both classes of shares.

To obtain more information and a prospectus for Institutional Service Shares,
investors may call 1-800-341-7400.

                         NOTES TO FINANCIAL STATEMENTS

                      Federated Short-Term Municipal Trust
                                 June 30, 1998

Organization

Federated Short-Term Municipal Trust (the "Trust") is registered under the
Investment Company Act of 1940, as amended (the "Act"), as a diversified,
open-end management investment company. The Trust offers two classes of shares:
Institutional Shares and Institutional Service Shares. The investment objective
of the Trust is to provide dividend income which is exempt from federal regular
income tax. The Trust pursues this investment objective by investing in a
portfolio of municipal securities with a dollar-weighted average maturity of
less than three years.

Significant Accounting Policies

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements. These
policies are in conformity with generally accepted accounting principles.

Investment Valuations

Municipal bonds are valued by an independent pricing service, taking into
consideration yield, liquidity, risk, credit quality, coupon, maturity, type of
issue, and any other factors or market data the pricing service deems relevant.
Short-term securities are valued at the prices provided by an independent
pricing service. However, short-term securities with remaining maturities of
sixty days or less at the time of purchase may be valued at amortized cost,
which approximates fair market value.

Investment Income, Expenses and Distributions

Interest income and expenses are accrued daily. Bond premium and discount, if
applicable, are amortized as required by the Internal Revenue Code, as amended
(the "Code"). Distributions to shareholders are recorded on the ex-dividend
date.

Income and capital gain distributions are determined in accordance with income
tax regulations which may differ from generally accepted accounting principles.
These differences are primarily due to expired capital loss carryforwards. The
following reclassification has been made to the financial statements.

          Increase (Decrease)
- -------------------------------------
                   Accumulated Net
Paid In Capital  Realized Gain (Loss)
- -------------------------------------
   ($1,720,574)  $1,720,574

Federal Taxes

It is the Trust's policy to comply with the provisions of the Code applicable to
regulated investment companies and to distribute to shareholders each year
substantially all of its income. Accordingly, no provisions for federal tax are
necessary.

At June 30, 1998, the Trust, for federal tax purposes, had a capital loss
carryforward of $4,030,794 which will reduce the Trust's taxable income arising
from future net realized gain on investments, if any, to the extent permitted by
the Code, and thus will reduce the amount of the distributions to shareholders
which would otherwise be necessary to relieve the Trust of any liability for
federal tax. Pursuant to the Code, such capital loss carryforward will expire as
follows:

                     2005                               $  170,193
 When-Issued and Delayed Delivery Transactions
</TABLE>

The Trust may engage in when-issued or delayed delivery transactions. The Trust
records when-issued securities on the trade date and maintains security
positions such that sufficient liquid assets will be available to make payment
for the securities purchased. Securities purchased on a when-issued or delayed
delivery basis are marked to market daily and begin earning interest on the
settlement date.

Use of Estimates

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts of assets, liabilities, expenses and revenues reported in the
financial statements. Actual results could differ from those estimated.

Other
Investment transactions are accounted for on the trade date.

Shares of Beneficial Interest
The Declaration of Trust permits the Trustees to issue an unlimited number of
full and fractional shares of beneficial interest (without par value) for each
class of shares.

Transactions in shares were as follows:

Investment Advisory Fee and Other Transactions with Affiliates
Investment Advisory Fee

Federated Management, the Trust's investment adviser (the "Adviser"), receives
for its services an annual investment advisory fee equal to 0.40% of the Trust's
average daily net assets. The Adviser will waive, to the extent of its advisory
fee, the amount, if any, by which the Trust's aggregate annual operating
expenses (excluding interest, taxes, brokerage commissions, expenses of
registering and qualifying the Trust and its shares under federal and state laws
and regulations, expenses of withholding taxes, and extraordinary expenses)
exceed 0.45% of average daily net assets of the Trust.

Administrative Fee

Federated Services Company ("FServ"), under the Administrative Services
Agreement, provides the Trust with administrative personnel and services. The
fee paid to FServ is based on the level of average aggregate daily net assets of
all funds advised by subsidiaries of Federated Investors, Inc. for the period.
The administrative fee received during the period of the Administrative Services
Agreement shall be at least $125,000 per portfolio and $30,000 per each
additional class of shares.

Distribution Services Fee

The Trust has adopted a Distribution Plan (the "Plan") pursuant to Rule 12b-1
under the Act. Under the terms of the Plan, the Trust will compensate Federated
Securities Corp. ("FSC"), the principal distributor, from the net assets of the
Trust to finance activities intended to result in the sale of the Trust's
Institutional Service Shares. The Plan provides that the Trust may incur
distribution expenses of up to 0.25% of the average daily net assets of the
Institutional Service Shares, annually, to compensate FSC. The distributor may
voluntarily choose to waive any portion of its fee. The distributor can modify
or terminate this voluntary waiver at any time at its sole discretion.

Shareholder Services Fee

Under the terms of a Shareholder Services Agreement with Federated Shareholder
Services ("FSS"), the Trust will pay FSS up to 0.25% of average daily net assets
of the Trust for the period. The fee paid to FSS is used to finance certain
services for shareholders and to maintain shareholder accounts. FSS may
voluntarily choose to waive any portion of its fee. FSS can modify or terminate
this voluntary waiver at any time at its sole discretion.

Transfer and Dividend Disbursing Agent Fees and Expenses

FServ, through its subsidiary, Federated Shareholder Services Company ("FSSC")
serves as transfer and dividend disbursing agent for the Trust. The fee paid to
FSSC is based on the size, type, and number of accounts and transactions made by
shareholders.

Portfolio Accounting Fees

FServ maintains the Trust's accounting records for which it receives a fee. The
fee is based on the level of the Trust's average daily net assets for the
period, plus out-of-pocket expenses.

General
Certain of the Officers and Trustees of the Trust are Officers and Directors or
Trustees of the above companies.

Year 2000 (unaudited)

Similar to other financial organizations, the Trust could be adversely affected
if the computer systems used by the Trust's service providers do not properly
process and calculate date-related information and data from and after January

believe are reasonably designed to address the Year 2000 issue with respect to

General Information About the Trust
The Trust was established as a Massachusetts business trust under a Declaration
of Trust dated May 8, 1981. The name of the Trust was Federated
Short-Intermediate Municipal Trust prior to August 23, 1993. On August 23, 1993,
the shareholders of the Trust voted to change the name of the Trust to
Short-Term Municipal Trust. On December 15, 1994, the name of the Trust was
changed from Short-Term Municipal Trust to Federated Short-Term Municipal Trust.

Shares of the Trust are offered in two classes, known as Institutional Shares
and Institutional Service Shares (individually and collectively referred to as
"Shares," as the context may require). This Statement of Additional Information
relates to the above-mentioned Shares of the Trust.

Investment Objective and Policies
The investment objective of the Trust is to provide dividend income which is
exempt from federal regular income tax.

Acceptable Investments

The Trust attempts to achieve its investment objective by investing at least 80%
of its net assets in a diversified portfolio of municipal securities or by
investing its assets so that at least 80% of its income will be tax exempt. The
investment objective and the policy stated above cannot be changed without the
approval of shareholders. The investment policies described below may be changed
without shareholder approval.

   Characteristics

      The municipal securities in which the Trust invests have the
      characteristics set forth in the prospectuses. The Trust may use similar
      services or ratings other than Moody's Investors Service, Inc. ("Moody's")
      Standard & Poor's ("S&P"), or Fitch IBCA, Inc. ("Fitch"). If a security's
      rating is reduced below the required minimum after the Trust has purchased
      it, the Trust is not required to sell the security, but may consider doing
      so. If ratings made by Moody's, S&P, or Fitch change because of changes in
      those organizations or in their rating systems, the Trust will try to use
      comparable ratings as standards in accordance with the investment policies
      described in the Shares' prospectuses.

   Participation Interests

      The financial institutions from which the Trust purchases participation
      interests frequently provide or secure from another financial institution
      irrevocable letters of credit or guarantees and give the Trust the right
      to demand payment of the principal amounts of the participation interests
      plus accrued interest on short notice (usually within seven days). These
      financial institutions may charge certain fees in connection with their
      repurchase commitments, including a fee equal to the excess of the
      interest paid on the municipal securities over the negotiated yield at
      which the participation interests were purchased by the Trust. By
      purchasing participation interests having a seven day demand feature, the
      Trust is buying a security meeting the quality requirements of the Trust
      and also is receiving the tax-free benefits of the underlying securities.

   Variable Rate Municipal Securities

      Variable interest rates generally reduce changes in the market value of
      municipal securities from their original purchase prices. Accordingly, as
      interest rates decrease or increase, the potential for capital
      appreciation or depreciation is less for variable rate municipal
      securities than for fixed income obligations. Many municipal securities
      with variable interest rates purchased by the Trust are subject to
      repayment of principal (usually within seven days) on the Trust's demand.
      For purposes of determining the Trust's average maturity, the maturities
      of these variable rate demand municipal securities (including
      participation interests) are the longer of the periods remaining until the
      next readjustment of their interest rates or the periods remaining until
      their principal amounts can be recovered by exercising the right to demand
      payment. The terms of these variable rate demand instruments require
      payment of principal and accrued interest from the issuer of the municipal
      obligations, the issuer of the participation interests, or a guarantor of
      either issuer.

Futures Transactions

A futures contract is a firm commitment by two parties: the seller who agrees to
make delivery of the specific type of security called for in the contract
("going short") and the buyer who agrees to take delivery of the security
("going long") at a certain time in the future. In the fixed income securities
market, price moves inversely to interest rates. A rise in rates means a drop in
price. Conversely, a drop in rates means a rise in price. In order to hedge its
holdings of fixed income securities against a rise in market interest rates, the
Trust could enter into contracts to deliver securities at a predetermined price
(i.e., "go short") to protect itself against the possibility that the prices of
its fixed income securities may decline during the Trust's anticipated holding
period. The Trust would agree to purchase securities in the future at a
predetermined price (i.e., "go long") to hedge against a decline in market
interest rates.

   "Margin" in Futures Transactions

      Unlike the purchase or sale of a security, the Trust does not pay or
      receive money upon the purchase or sale of a futures contract. Rather, the
      Trust is required to deposit an amount of "initial margin" in liquid
      securities with its custodian (or the broker, if legally permitted). The
      nature of initial margin in futures transactions is different from that of
      margin in securities transactions in that futures contract initial margin
      does not involve the borrowing of funds by the Trust to finance the
      transactions. Initial margin is in the nature of a performance bond or
      good faith deposit on the contract which is returned to the Trust upon
      termination of the futures contract, assuming all contractual obligations
      have been satisfied.

      A futures contract held by the Trust is valued daily at the official
      settlement price of the exchange on which it is traded. Each day the Trust
      pays or receives cash, called "variation margin," equal to the daily
      change in value of the futures contract. This process is known as "marking
      to market." Variation margin does not represent a borrowing or loan by the
      Trust but is instead settlement between the Trust and the broker of the
      amount one would owe the other if the futures contract expired. In
      computing its daily net asset value ("NAV"), the Trust will mark-to-market
      its open futures positions.

When-Issued and Delayed Delivery Transactions

These transactions are made to secure what is considered to be an advantageous
price and yield for the Trust. Settlement dates may be a month or more after
entering into these transactions, and the market values of the securities
purchased may vary from the purchase prices. No fees or other expenses, other
than normal transaction costs, are incurred. However, liquid assets of the Trust
sufficient to make payment for the securities to be purchased are segregated on
the Trust's records at the trade date. These securities are marked to market
daily and maintained until the transaction is settled. The Trust does not intend
to engage in when-issued and delayed delivery transactions to the extent that
would cause the segregation of more than 20% of the total value of its assets.

Investing in Securities of Other Investment Companies

The Trust may invest in the securities of affiliated money market funds as an
efficient means of managing the Trust's uninvested cash.

Portfolio Turnover

The Trust will not attempt to set or meet a portfolio turnover rate since any
turnover would be incidental to transactions undertaken in an attempt to achieve
the Trust's investment objective. During the fiscal years ended June 30, 1998
and 1997, the portfolio turnover rates were 33% and 50%, respectively.

Investment Limitations
   Diversification of Investments

      The Trust will not purchase the securities of any issuer (except cash and
      cash instruments and securities issued or guaranteed by the United States
      government, its agencies and instrumentalities) if, as a result, more than
      5 percent of its total assets would be invested in the securities of such
      issuer. For purposes of this limitation, each governmental subdivision,
      i.e., state, territory, possession of the United States or any political
      subdivision of any of the foregoing, including agencies, authorities,
      instrumentalities, or similar entities, or of the District of Columbia,
      shall be considered a separate issuer if its assets and revenues are
      separate from those of the governmental body creating it and the security
      is backed only by its own assets and revenues. In the case of an
      industrial development bond, if the security is backed only by the assets
      and revenues of a non-governmental user, then such non-governmental user
      will be deemed to be the sole issuer. If, however, in the case of an
      industrial development bond or governmental issued security, a
      governmental or some other entity guarantees the security, such guarantee
      would be considered a separate security issued by the guarantor as well as
      the other issuer (as above defined) subject to limited exclusions allowed
      by the Investment Company Act of 1940.

   Borrowing Money

      The Trust will not borrow money except as a temporary measure for
      extraordinary or emergency purposes and then (a) only in amounts not in
      excess of 5% of the value of its total assets or (b) in an amount up to
      one-third of the value of its total assets, including the amount borrowed.
      (This borrowing provision is not for investment leverage but solely to
      facilitate management of the portfolio by enabling the Trust to meet
      redemption requests when the liquidation of portfolio securities would be
      inconvenient or disadvantageous.) While any such borrowings are
      outstanding, no net purchases of investment securities will be made by the
      Trust. If, due to market fluctuations or other reasons, the value of the
      Trust's assets falls below 300% of its borrowings, the Trust will reduce
      its borrowings within three business days. To do this, the Trust may have
      to sell a portion of its investments at a time when it may be
      disadvantageous to do so.

   Pledging Assets

      The Trust will not mortgage, pledge, or hypothecate its assets except to
      secure permitted borrowings. In those cases, it may mortgage, pledge, or
      hypothecate assets having a market value not exceeding 10% of the value of
      total assets at the time of the borrowing.

   Underwriting

      The Trust will not underwrite any issue of securities, except as it may be
      deemed to be an underwriter under the Securities Act of 1933 in connection
      with the sale of securities in accordance with its investment objective,
      policies, and limitations.

   Investing in Real Estate

      The Trust will not buy or sell real estate, although it may invest in
municipal securities secured by real estate or interests in real estate.

   Investing in Commodities or Minerals

      The Trust will not buy or sell commodities, commodity contracts, or oil,
gas, or other mineral exploration or development programs.

   Making Loans

      The Trust will not make loans, but may acquire publicly or nonpublicly
      issued municipal securities as permitted by its investment objective,
      policies, and limitations.



<PAGE>


   Selling Short and Buying on Margin

      The Trust will not sell any securities short or purchase any securities on
      margin but may obtain such short-term credits as may be necessary for
      clearance of purchases and sales of securities.

   Issuing Senior Securities

      The Trust will not issue senior securities, except as permitted by its
investment objective and policies.

 The above investment limitations cannot be changed without shareholder
 approval. The following limitations, however, may be changed by the Trustees
 without shareholder approval. Shareholders will be notified before any material
 change in these limitations becomes effective.

   Acquiring Securities

      The Trust will not acquire voting securities, except as part of a merger,
consolidation, reorganization, or acquisition of assets.

   Investing in Illiquid Securities

      The Trust will not invest more than 15% of the value of its net assets in
      illiquid securities, including repurchase agreements providing for
      settlement in more than seven days after notice and certain restricted
      securities.

   The Trust does not intend to purchase securities if, as a result of such
   purchase, more than 25% of the value of its assets would be invested in the
   securities of governmental subdivisions located in any one state, territory,
   or possession of the United States.

   Except with respect to borrowing money, if a percentage limitation is adhered
   to at the time of the investment, a later increase or decrease in percentage
   resulting from any change in value or net assets will not result in violation
   of such restriction.

   The Trust did not borrow money, pledge securities or invest in illiquid
   securities or restricted securities in excess of 5% of the value of its total
   assets during the last fiscal year and has no present intent to do so in the
   coming fiscal year.

   For purposes of this limitation, the Trust considers cash instruments and
   items to be instruments issued by a U.S. branch of a domestic bank or savings
   association having capital, surplus, and undivided profits in excess of
   $100,000,000 at the time of the investment.

*    Information is furnished for the fiscal year ended June 30, 1998.

     one portfolio.

  The information is provided for the last calendar year.



Trustee Liability

The Trust's Declaration of Trust provides that the Trustees will not be liable
for errors of judgment or mistakes of fact or law. However, they are not
protected against any liability to which they would otherwise be subject by
reason of willful misfeasance, bad faith, gross negligence, or reckless
disregard of the duties involved in the conduct of their office.

Investment Advisory Services
Adviser to the Trust

The Trust's investment adviser is Federated Management (the "Adviser"). It is a
subsidiary of Federated Investors, Inc. All of the securities of Federated
Investors, Inc. are owned by a trust, the trustees of which are John F. Donahue,
his wife, and his son, J. Christopher Donahue. The Adviser shall not be liable
to the Trust or its shareholders for any losses that may be sustained in the
purchase, holding, or sale of any security, for anything done or omitted by it,
except acts or omissions involving willful misfeasance, bad faith, gross
negligence, or reckless disregard of the duties imposed upon it by its contract
with the Trust.

Advisory Fees
For its advisory services, Federated Management receives an annual investment
advisory fee as described in the prospectuses. During the fiscal years ended
June 30, 1998, 1997, and 1996, the Trust's adviser earned $799,123, $866,632,
and $837,213, respectively, which were reduced by $256,084, $293,339, and
$266,026, respectively, because of undertakings to limit the Trust's expenses.

Brokerage Transactions
When selecting brokers and dealers to handle the purchase and sale of portfolio
instruments, the adviser looks for prompt execution of the order at a favorable
price. In working with dealers, the adviser will generally use those who are
recognized dealers in specific portfolio instruments, except when a better price
and execution of the order can be obtained elsewhere. The adviser makes
decisions on portfolio transactions and selects brokers and dealers subject to
guidelines established by the Trustees. The adviser may select brokers and
dealers who offer brokerage and research services. These services may be
furnished directly to the Trust or to the adviser and may include: advice as to
the advisability of investing in securities; security analysis and reports;
economic studies; industry studies; receipt of quotations for portfolio
evaluations; and similar services. Research services provided by brokers and
dealers may be used by the adviser or its affiliates in advising the Trust and
other accounts. To the extent that receipt of these services may supplant
services for which the adviser or its affiliates might otherwise have paid, it
would tend to reduce their expenses. The adviser and its affiliates exercise
reasonable business judgment in selecting brokers who offer brokerage and
research services to execute securities transactions. They determine in good
faith that commissions charged by such persons are reasonable in relationship to
the value of the brokerage and research services provided. During the fiscal
years ended June 30, 1998, 1997 and 1996, the Trust paid no brokerage
commissions. Although investment decisions for the Trust are made independently
from those of the other accounts managed by the adviser, investments of the type
the Trust may make may also be made by those other accounts. When the Trust and
one or more other accounts managed by the adviser are prepared to invest in, or
desire to dispose of, the same security, available investments or opportunities
for sales will be allocated in a manner believed by the adviser to be equitable
to each. In some cases, this procedure may adversely affect the price paid or
received by the Trust or the size of the position obtained or disposed of by the
Trust. In other cases, however, it is believed that coordination and the ability
to participate in volume transactions will be to the benefit of the Trust.

Other Services
Trust Administration
Federated Services Company, a subsidiary of Federated Investors, Inc., provides
administrative personnel and services to the Trust for a fee as described in the
prospectuses. From March 1, 1994 to March 1, 1996, Federated Administrative
Services, a subsidiary of Federated Investors, Inc., served as the Trust's
Administrator. For purposes of this Statement of Additional Information,
Federated Services Company and Federated Administrative Services may hereinafter
collectively be referred to as the "Administrators." For the fiscal years ended
June 30, 1998, 1997, and 1996, the Administrators earned $155,000, $163,655, and
$158,326, respectively.

Custodian and Portfolio Accountant
State Street Bank and Trust Company, Boston, MA, is custodian for the securities
and cash of the Trust. Federated Services Company, Pittsburgh, PA, provides
certain accounting and recordkeeping services with respect to the Trust's
portfolio of investments. The fee paid for this service is based upon the level
of the Trust's average net assets for the period plus out-of-pocket expenses.

Transfer Agent
Federated Services Company, through its registered transfer agent, Federated
Shareholder Services Company, maintains all necessary shareholder records. For
its services, the transfer agent receives a fee based on size, type, number of
accounts and transactions made by shareholders.

Independent Public Accountants

The independent auditors for the Trust are Arthur Andersen LLP, Pittsburgh, PA.

Purchasing Shares
Shares are sold at their net asset value without a sales charge on days the New
York Stock Exchange is open for business. The procedure for purchasing Shares is
explained in the respective prospectuses under "Investing in Institutional
Shares" or "Investing in Institutional Service Shares."

Distribution Plan (Institutional  Service Shares Only) and Shareholder  Services
Agreement

These arrangements permit the payment of fees to financial institutions, the
distributor, and Federated Shareholder Services to stimulate distribution
activities and to cause services to be provided to shareholders by a
representative who has knowledge of the shareholder's particular circumstances
and goals. These activities and services may include, but are not limited to,
marketing efforts; providing office space, equipment, telephone facilities, and
various clerical, supervisory, computer, and other personnel as necessary or
beneficial to establish and maintain shareholder accounts and records;
processing purchase and redemption transactions and automatic investments of
client account cash balances; answering routine client inquiries; and assisting
clients in changing dividend options, account designations, and addresses. With
respect to the Institutional Service Shares, by adopting the Distribution Plan,
the Board of Trustees expects that the Trust will be able to achieve a more
predictable flow of cash for investment purposes and to meet redemptions. This
will facilitate more efficient portfolio management and assist the Trust in
pursuing its investment objectives. By identifying potential investors whose
needs are served by the Trust's objectives, and properly servicing these
accounts, it may be possible to curb sharp fluctuations in rates of redemptions
and sales. Other benefits, which may be realized under either arrangement, may
include: (1) providing personal services to shareholders; (2) investing
shareholder assets with a minimum of delay and administrative detail; (3)
enhancing shareholder recordkeeping systems; and (4) responding promptly to
shareholders' requests and inquiries concerning their accounts.

For the fiscal year ended June 30, 1998, payments in the amount of $22,281 were
made pursuant to the Distribution Plan (Institutional Service Shares only) of
which $21,390 was waived. In addition, for this period, the Trust paid
shareholder service fees in the amount of $477,166, of which $477,166 was waived
for Institutional Shares and $22,281, of which $891 was waived for Institutional
Service Shares.

Determining Net Asset Value
Net asset value generally changes each day. The days on which the net asset
value is calculated by the Trust are described in each respective prospectus.

Valuing Municipal Securities

The Trustees use an independent pricing service to value municipal securities.
The independent pricing service takes into consideration: yield; stability;
risk; quality; coupon rate; maturity; type of issue; trading characteristics;
special circumstances of a security or trading market; and any other factors or
market data it considers relevant in determining valuations for normal
institutional size trading units of debt securities and does not rely
exclusively on quoted prices.

Use of Amortized Cost

The Trustees have decided that the fair value of municipal securities authorized
to be purchased by the Trust with remaining maturities of 60 days or less at the
time of purchase shall be their amortized cost value, unless the particular
circumstances of the security indicate otherwise. Under this method, portfolio
instruments and assets are valued at the acquisition cost as adjusted for
amortization of premium or accumulation of discount rather than at current
market value. The Executive Committee continually assesses this method of
valuation and recommends changes where necessary to assure that the Trust's
portfolio instruments are valued at their fair value as determined in good faith
by the Trustees.

Redeeming Shares
The Trust redeems Shares at the next computed net asset value after the Trust
receives the redemption request. Redemption procedures are explained in each
respective prospectus under "Redeeming Institutional Shares" or "Redeeming
Institutional Service Shares." Although State Street Bank does not charge for
telephone redemptions, it reserves the right to charge a fee for the cost of
wire-transferred redemptions of less than $5,000.

Redemption in Kind

Although the Trust intends to redeem shares in cash, it reserves the right under
certain circumstances to pay the redemption price in whole or in part by a
distribution of securities from the Trust's portfolio. Redemption in kind will
be made in conformity with applicable Securities and Exchange Commission rules,
taking such securities at the same value employed in determining net asset value
and selecting the securities in a manner the Trustees determine to be fair and
equitable.

The Trust has elected to be governed by Rule 18f-1 of the Investment Company Act
of 1940 under which the Trust is obligated to redeem shares for any one
shareholder in cash only up to a lesser of $250,000 or 1% of a class's net asset
value during any 90-day period.

Massachusetts Partnership Law
Under certain circumstances, shareholders may be held personally liable as
partners under Massachusetts law for acts or obligations of the Trust. To
protect shareholders, the Trust has filed legal documents with Massachusetts
that expressly disclaim the liability of its shareholders for such acts or
obligations of the Trust. These documents require notice of this disclaimer to
be given in each agreement, obligation, or instrument that the Trust or its
Trustees enter into or sign on behalf of the Trust. In the unlikely event a
shareholder is held personally liable for the Trust's obligations, the Trust is
required to use its property to protect or compensate the shareholder. On
request, the Trust will defend any claim made and pay any judgment against a
shareholder for any act or obligation of the Trust. Therefore, financial loss
resulting from liability as a shareholder will occur only if the Trust itself
cannot meet its obligations to indemnify shareholders and pay judgments against
them from its assets.

Tax Status
The Trust's Tax Status

The Trust will pay no federal income tax because it expects to meet the
requirements of Subchapter M of the Internal Revenue Code of 1986, as amended,
applicable to regulated investment companies and to receive the special tax
treatment afforded to such companies. To qualify for this treatment, the Trust
must, among other requirements:

  o derive at least 90% of its gross income from dividends, interest, and gains 
    from the sale of securities;

  o invest in securities within certain statutory limits; and

  o distribute to its shareholders at least 90% of its net income earned during 
    the year.

Total Return
The average annual total return for each class of shares of the Trust is the
average compounded rate of return for a given period that would equate a $1,000
initial investment to the ending redeemable value of that investment. The ending
redeemable value is computed by multiplying the number of shares owned at the
end of the period by the net asset value per share at the end of the period. The
number of shares owned at the end of the period is based on the number of shares
purchased at the beginning of the period with $1,000, adjusted over the period
by any additional shares, assuming monthly reinvestment of all dividends and
distributions.

The Trust's average annual total returns for Institutional Shares for the
one-year, five-year, and ten-year periods ended June 30, 1998, were 4.68%,
4.07%, and 4.96%, respectively. The Trust's average annual total return for
Institutional Service Shares for the fiscal year ended June 30, 1998 and for the
period since inception (August 31, 1993, date of initial public offering), to
June 30, 1998 was 4.41% and 3.85% respectively.

Yield
The Trust's yields for the thirty-day period ended June 30, 1998, for
Institutional Shares and Institutional Service Shares were 3.78% and 3.53%,
respectively.

The yield for both classes of shares of the Trust is determined by dividing the
net investment income per share (as defined by the Securities and Exchange
Commission) earned by either class of shares over a thirty-day period by the
maximum offering price per share of either class on the last day of the period.
This value is then annualized using semi-annual compounding. This means that the
amount of income generated during the thirty-day period is assumed to be
generated each month over a twelve-month period and is reinvested every six
months. The yield does not necessarily reflect income actually earned by the
Trust because of certain adjustments required by the Securities and Exchange
Commission and, therefore, may not correlate to the dividends or other
distributions paid to shareholders.

To the extent that financial intermediaries charge fees in connection with
services provided in conjunction with an investment in either class of shares,
performance will be reduced for those shareholders paying those fees.

Tax-Equivalent Yield
The Trust's tax-equivalent yields for the thirty-day period ended June 30, 1998,
for Institutional Shares and Institutional Service Shares were 5.25% and 4.90%,
respectively.

The tax-equivalent yield of the Trust is calculated similarly to the yield, but
is adjusted to reflect the taxable yield that the Trust would have had to earn
to equal its actual yield, assuming the shareholder is in the 28% tax-bracket
and that income is 100% tax-exempt.

Tax-Equivalency Table

The Trust may also use a tax-equivalency table in advertising and sales
literature. The interest earned by the municipal bonds in the Trust's portfolio
generally remains free from federal regular income tax,* and is often free from
state and local taxes as well. As the table below indicates, a "tax-free"
investment is an attractive choice for investors, particularly in times of
narrow spreads between tax-free and taxable yields.

taxable yield equivalent.

Performance Comparisons
The performance of both classes of Shares depends upon such variables as:

  o portfolio quality;

  o average portfolio maturity;

  o type of instruments in which the portfolio is invested;

  o changes in interest rates and market value of portfolio securities;

  o changes in the Trust's expenses or either class of Shares' expenses; and

  o various other factors.

Either class of Shares' performance fluctuates on a daily basis largely because
net earnings and offering price per share fluctuate daily. Both net earnings and
offering price per share are factors in the computation of yield and total
return. Investors may use financial publications and/or indices to obtain a more
complete view of the Trust's performance. When comparing performance, investors
should consider all relevant factors, such as the composition of any index used,
prevailing market conditions, portfolio compositions of other funds, and methods
used to value portfolio securities and compute offering price. The financial
publications and/or indices which the Trust uses in advertising may include:

  o Lipper Analytical Services, Inc., ranks funds in various fund categories by
    making comparative calculations using total return. Total return assumes the
    reinvestment of all capital gains distributions and income dividends and
    takes into account any change in offering price over a specific period of
    time. From time to time, the Trust will quote its Lipper ranking in the
    "intermediate municipal bond funds" category in advertising and sales
    literature.

  o The Lehman Brothers Municipal Index/1-Year is an unmanaged index of
    municipal bonds issued after January 1, 1991 with a minimum credit rating of
    at least Baa, which have been issued as part of a deal of at least $50
    million, have a maturity value of at least $3 million and mature in at least
    1, but not more than 2 years. As of January 1996, the index also includes
    zero coupon bonds and bonds subject to the Alternative Minimum Tax.

  o The Lehman Brothers Municipal Index/3 Year is an unmanaged index of
    municipal bonds issued after January 1, 1991 with a minimum credit rating of
    at least Baa, which have been issued as part of a deal of at least $50
    million, have a maturity value of at least $3 million, and a maturity range
    of 1-5 years. As of January 1996, the index also includes zero coupon bonds
    and bonds subject to the Alternative Minimum Tax.

  o Morningstar, Inc., An independent rating service, is the publisher of the
    bi-weekly Mutual Fund Values. Mutual Fund Values rates more than 1,000
    NASDAQ-listed mutual funds of all types, according to their risk-adjusted
    returns. The maximum rating is five stars, and ratings are effective for two
    weeks.

Advertising and other promotional literature may include charts, graphs and
other illustrations using the Trust's returns, or returns in general, that
demonstrate basic investment concepts such as tax-deferred compounding,
dollar-cost averaging and systematic investment. In addition, the Trust can
compare its performance, or performance for the types of securities in which it
invests, to a variety of other investments, such as bank savings accounts,
certificates of deposit, and Treasury bills.

Economic and Market Information

Advertising and sales literature for the Trust may include discussions of
economic, financial and political developments and their effect on the
securities market. Such discussions may take the form of commentary on these
developments by the Trust portfolio managers and their views and analysis on how
such developments could affect the Trust. In addition, advertising and sales
literature may quote statistics and give general information about the mutual
fund industry, including the growth of the industry, from sources such as the
Investment Company Institute.

Appendix
Standard and Poor's ("S&P") Municipal Bond Ratings

AAA--Debt rated "AAA" has the highest rating assigned by S&P. Capacity to pay
interest and repay principal is extremely strong.

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

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

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

NR--Indicates that no public rating has been requested, that there is
insufficient information on which to base a rating, or that S&P does not rate a
particular type of obligation as a matter of policy.

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

Moody's Investors Services, Inc. ("Moody's") Municipal Bond Ratings

Aaa--Bonds which are rated Aaa are judged to be of the best quality. They carry
the smallest degree of investment risk and are generally referred to as "gilt
edged." Interest payments are protected by a large or by an exceptionally stable
margin and principal is secure. While the various protective elements are likely
to change, such changes as can be visualized are most unlikely to impair the
fundamentally strong position of such issues.

Aa--Bonds which are rated Aa are judged to be of high quality by all standards.
Together with the Aaa group they comprise what are generally known as high grade
bonds. They are rated lower than the best bonds because margins of protection
may not be as large as in Aaa securities or fluctuation of protective elements
may be of greater amplitude or there may be other elements present which make
the long-term risks appear somewhat larger than in Aaa securities.

A--Bonds which are rated A possess many favorable investment attributes and are
to be considered as upper medium grade obligations. Factors giving security to
principal and interest are considered adequate but elements may be present which
suggest a susceptibility to impairment sometime in the future.

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

NR--Not rated by Moody's.

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

Fitch IBCA, Inc. ("Fitch") Investment Grade Bond Ratings

AAA--Bonds considered to be investment grade and of the highest credit quality.
The obligor has an exceptionally strong ability to pay interest and repay
principal, which is unlikely to be affected by reasonably foreseeable events.

AA--Bonds considered to be investment grade and of very high credit quality. The
obligor's ability to pay interest and repay principal is very strong, although
not quite as strong as bonds rated "AAA." Because bonds rated in the "AAA" and
"AA" categories are not significantly vulnerable to foreseeable future
developments, short-term debt of these issuers is generally rated "F-1+."

A--Bonds considered to be investment grade and of high credit quality. The
obligor's ability to pay interest and repay principal is considered strong, but
may be more vulnerable to adverse changes in economic conditions and
circumstances than bonds with higher ratings.

BBB--Bonds considered to be investment grade and of satisfactory credit quality.

NR--NR indicates that Fitch does not rate the specific issue.

Plus (+) or Minus (-): Plus and minus signs are used with a rating symbol to
indicate the relative position of a credit within the rating category. Plus and
minus signs, however, are not used in the "AAA" category.

Standard and Poor's Municipal Note Ratings

SP-1--Very strong or strong capacity to pay principal and interest. Those issues
determined to possess overwhelming safety characteristics will be given a plus
sign (+) designation.

SP-2--Satisfactory capacity to pay principal and interest.

Moody's Investors Services, Inc. Short-Term Loan Ratings

MIG1/VMIG1--This designation denotes best quality. There is present strong
protection by established cash flows, superior liquidity support or demonstrated
broad based access to the market for refinancing.

MIG2/VMIG2--This designation denotes high quality. Margins of protection are
ample although not so large as in the preceding group.

Standard and Poor's Commercial Paper Ratings

A-1--This highest category indicates that the 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--Capacity for timely payment on issues with this designation is
satisfactory. However, the relative degree of safety is not as high for issues
designated A-1.

Moody's Investors Services, Inc. Commercial Paper Ratings

P-1--Issuers rated P-1 (or related supporting institutions) have a superior
capacity for repayment of short-term promissory obligations. P-1 repayment
capacity will normally be evidenced by the following characteristics:

  o leading market positions in well-established industries;

  o high rates of return on funds employed;

  o conservative capitalization structure with moderate reliance on debt and 
    ample asset protection;

  o broad margins in earning coverage of fixed financial charges and high 
    internal cash generation; and

  o well-established access to a range of financial markets and assured sources
of alternative liquidity.

P-2--Issuers rated P-2 (or related supporting institutions) have a strong
capacity for repayment of short-term promissory obligations. This will normally
be evidenced by many of the characteristics cited above, but to a lesser degree.
Earnings trends and coverage ratios, while sound, will be more subject to
variation. Capitalization characteristics, while still appropriate, may be more
affected by external conditions. Ample alternate liquidity is maintained.

GENERAL INFORMATION

The Trust was established as a Massachusetts business trust under a Declaration
of Trust dated May 8, 1981. The Declaration of Trust permits the Trust to offer
separate series of shares of beneficial interest representing interests in
separate portfolios of securities. The shares in any one portfolio may be
offered in separate classes. As of the date of this prospectus, the Board of
Trustees (the "Trustees") has established two classes of shares of the Trust,
known as Institutional Service Shares and Institutional Shares. This prospectus
relates only to Institutional Service Shares (the "Shares") of the Trust.


Shares of the Trust are sold primarily to retail and private banking customers
of financial institutions as a convenient means of accumulating an interest in a
professionally managed, diversified portfolio of municipal securities. A minimum
initial investment of $25,000 over a 90-day period is required. The Trust may
not be a suitable investment for retirement plans since it invests in municipal
securities.

Shares are currently sold and redeemed at net asset value without a sales charge
imposed by the Trust.


Year 2000 Statement

Like other mutual funds and business organizations worldwide, the Trust's
service providers (among them, the adviser, distributor, administrator and
transfer agent) must ensure that their computer systems are adjusted to properly
process and calculate date-related information from and after January 1, 2000.
Many software programs and, to a lesser extent, the computer hardware in use
today cannot distinguish the year 2000 from the year 1900. Such a design flaw
could have a negative impact in the handling of securities trades, pricing and
accounting services. The Trust and its service providers are actively working on
necessary changes to computer systems to deal with the year 2000 issue and
believe that systems will be year 2000 compliant when required. Analysis
continues regarding the financial impact of instituting a year 2000 compliant
program on the Trust's operations


                             INVESTMENT INFORMATION

Investment Objective

The investment objective of the Trust is to provide dividend income which is
exempt from federal regular income tax. Interest income of the Trust that is
exempt from federal regular income tax retains its tax-free status when
distributed to the Trust's shareholders. The Trust attempts to achieve its
investment objective by investing at least 80% of its net assets in a
diversified portfolio of municipal securities or by investing its assets so that
at least 80% of its income will be tax-exempt. While there is no assurance that
the Trust will achieve its investment objective, it endeavors to do so by
following the investment policies described in this prospectus. The investment
objective, and the above investment policy, cannot be changed without approval
of shareholders.

Investment Policies

The investment policies described below may be changed by the Trustees without
shareholder approval. Shareholders will be notified before any material change
in these policies becomes effective.

Acceptable Investments

The municipal securities in which the Trust invests are:

 .  debt obligations issued by or on behalf of any state, territory, or
   possession of the United States, including the District of Columbia, or any
   political subdivision of any of these, including industrial development
   bonds, the interest from which is, in the opinion of bond counsel for the
   issuers or in the opinion of officers of the Trust and/or the investment
   adviser to the Trust, exempt from federal regular income tax; and

 .  participation interests, as described below, in any of the above obligations.

Average Maturity

The dollar-weighted average maturity of the Trust's portfolio of municipal
securities will be less than three years. For purposes of determining the
dollar-weighted average maturity of the Trust's portfolio, the maturity of a
municipal security will be its ultimate maturity, unless it is probable that the
issuer of the security will take advantage of maturity-shortening devices such
as a call, refunding, or redemption provision, in which case the maturity date
will be the date on which it is probable that the security will be called,
refunded, or redeemed. If the municipal security includes the right to demand
payment, the maturity of the security for purposes of determining the Trust's
dollar-weighted average maturity will be the period remaining until the
principal amount of the security can be recovered by exercising the right to
demand payment.

Characteristics

The municipal securities in which the Trust invests are:

 .  rated within the four highest ratings for municipal securities by Moody's
   Investors Service, Inc. ("Moody's") (Aaa, Aa, A, or Baa) or by Standard &
   Poor's ("S&P") and Fitch IBCA, Inc. ("Fitch") (AAA, AA, A, or BBB);

 .  guaranteed at the time of purchase by the U.S. government as to the payment
   of principal and interest;

 .  rated at the time of purchase within the two highest ratings categories of
   Moody's short-term municipal securities ratings, (MIG1/VMIG1, MIG2/VMIG2) or
   Moody's municipal commercial paper ratings, (P-1, P-2) or S&P's municipal
   note rating, (SP-1, SP-2) or S&P's municipal commercial paper and short-term
   ratings, (A-1, A-2); or

 .  unrated, if at the time of purchase, determined by the Trust's investment
   adviser to be of comparable quality to municipal securities as stated above.

Changes in economic or other circumstances are more likely to lead to weakened
capacity to make principal and interest payments higher than securities.


Downgraded securities will be evaluated on a case by case basis by the adviser.
The adviser will determine whether or not the security continues to be an
acceptable investment. If not, the security will be sold. The prices of fixed
income securities fluctuate inversely to the direction of interest rates. A
description of the rating categories is contained in the Appendix to the
Statement of Additional Information.

Participation Interests

The Trust may purchase participation interests from financial institutions such
as commercial banks, savings associations, and insurance companies. These
participation interests give the Trust an undivided interest in municipal
securities. The financial institutions from which the Trust purchases
participation interests frequently provide or secure irrevocable letters of
credit or guarantees to assure that the participation interests are of high
quality. The Trustees will determine that participation interests meet the
prescribed quality standards for the Trust.

Variable Rate Municipal Securities

SOME OF THE MUNICIPAL SECURITIES WHICH THE TRUST PURCHASES MAY HAVE VARIABLE
INTEREST RATES. VARIABLE INTEREST RATES ARE ORDINARILY BASED ON A PUBLISHED
INTEREST RATE OR INTEREST RATE INDEX OR SOME SIMILAR STANDARD, SUCH AS THE 91-
DAY U.S. TREASURY BILL RATE. VARIABLE RATE MUNICIPAL SECURITIES WILL BE TREATED
AS MATURING ON THE DATE OF THE NEXT SCHEDULED ADJUSTMENT TO THE INTEREST RATE
FOR PURPOSES OF DETERMINING THE DOLLAR-WEIGHTED AVERAGE MATURITY OF THE
PORTFOLIO.


Inverse Floaters

The Trust may invest in securities known as "inverse floaters" which represent
interests in municipal securities. The Trust intends to purchase inverse
floaters to assist in pursuing its investment objective. These obligations pay
interest rates that vary inversely with changes in the interest rates of
specified short-term municipal securities or an index of short-term municipal
securities. The interest rates on inverse floaters will typically decline as
short-term market interest rates increase and increase as short-term market
rates decline. Inverse floaters will generally respond to changes in market
interest rates more rapidly than fixed-rate long-term securities (typically
twice as fast). As a result, the market values of inverse floaters will
generally be more volatile than the market values of fixed-rate municipal
securities. Typically, the portion of the portfolio invested in inverse floaters
will be subject to additional volatility.

Financial Futures

The Trust may purchase and sell interest rate and index financial futures
contracts. These financial futures contracts may be used to hedge all or a
portion of its portfolio against changes in the market value of portfolio
securities and interest rates, provide additional liquidity, and accomplish its
current strategies in a more expeditious fashion. Financial futures contracts
call for the delivery of particular debt instruments at a certain time in the
future. The seller of the contract agrees to make delivery of the type of
instrument called for in the contract and the buyer agrees to take delivery of
the instrument at the specified future time.

As a matter of investment policy, which may be changed without shareholder
approval, the Trust may not purchase or sell futures contracts if immediately
thereafter the sum of the amount of margin deposits on the Trust's existing
futures positions would exceed 5% of the market value of the Trust's total
assets. When the Trust purchases futures contracts, an amount of municipal
securities, cash or cash equivalents, equal to the underlying commodity value of
the futures contracts (less any related margin deposits), will be deposited in a
segregated account with the Trust's custodian (or the broker, if legally
permitted) to collateralize the position.

 Risks

 When the Trust uses financial futures, there is a risk that the prices of the
 securities subject to the futures contracts may not correlate perfectly with
 the prices of the securities in the Trust's portfolio. This may cause the
 futures contract to react differently than the portfolio securities to market
 changes. In addition, the Trust's investment adviser could be incorrect in its
 expectations about the direction or extent of market factors such as interest
 rate movements. In these events, the Trust may lose money on the futures
 contract. It is not certain that a secondary market for positions in futures
 contracts will exist at all times. Although the investment adviser will
 consider liquidity before entering into futures transactions, there is no
 assurance that a liquid secondary market on an exchange or otherwise will exist
 for any particular futures contract at any particular time. The Trust's ability
 to establish and close out futures positions depends on this secondary market.


When-Issued and Delayed Delivery Transactions

The Trust may purchase municipal securities on a when-issued or delayed delivery
basis. These transactions are arrangements in which the Trust purchases
securities with payment and delivery scheduled for a future time. The seller's
failure to complete these transactions may cause the Trust to miss a price or
yield considered to be advantageous. Settlement dates may be a month or more
after entering into these transactions, and the market values of the securities
purchased may vary from the purchase prices. The Trust may dispose of a
commitment prior to settlement if the adviser deems it appropriate to do so. In
addition, the Trust may enter into transactions to sell its purchase commitments
to third parties at current market values and simultaneously acquire other
commitments to purchase similar securities at later dates. The Trust may realize
short-term profits or losses upon the sale of such commitments.


Investing in Securities of Other Investment Companies

The Trust may invest its assets in securities of other investment companies as
an efficient means of carrying out its investment policies. It should be noted
that investment companies incur certain expenses, such as management fees, and,
therefore, any investment by the Trust in shares of other investment companies
may be subject to such duplicate expenses.


Temporary Investments

From time to time on a temporary basis, when the investment adviser determines
that market conditions call for a temporary defensive posture, the Trust may
invest in short-term temporary investments which may or may not be exempt from
federal income tax. Temporary investments include: tax-exempt variable and
floating rate demand notes; tax-free commercial paper; other temporary municipal
securities; obligations issued or guaranteed by the U.S. government, its
agencies or instrumentalities; other debt securities; commercial paper;
certificates of deposit of domestic branches of U.S. banks; and repurchase
agreements (arrangements in which the organization selling the Trust a security
agrees at the time of sale to repurchase it at a mutually agreed upon time and
price).

There are no rating requirements applicable to temporary investments with the
exception of temporary municipal securities which are subject to the same rating
requirements as all other municipal securities in which the Trust invests.
However, the investment adviser will limit temporary investments to those it
considers to be of comparable quality to the acceptable investments of the
Trust.

Although the Trust is permitted to make taxable, temporary investments, there is
no current intention of generating income subject to federal regular income tax.

Municipal Securities

Municipal securities are generally issued to finance public works such as
airports, bridges, highways, housing, hospitals, mass transportation projects,
schools, streets, and water and sewer works. They are also issued to repay
outstanding obligations, to raise funds for general operating expenses, and to
make loans to other public institutions and facilities. Municipal securities
include industrial development bonds issued by or on behalf of public
authorities to provide financing aid to acquire sites or construct and equip
facilities for privately or publicly owned corporations. The availability of
this financing encourages these corporations to locate within the sponsoring
communities and thereby increases local employment. The two principal
classifications of municipal securities are "general obligation" and "revenue"
bonds. General obligation bonds are secured by the issuer's pledge of its full
faith and credit and taxing power for the payment of principal and interest.
Interest on and principal of revenue bonds, however, are payable only from the
revenue generated by the facility financed by the bond or other specified
sources of revenue. Revenue bonds do not represent a pledge of credit or create
any debt of or charge against the general revenues of a municipality or public
authority. Industrial development bonds are typically classified as revenue
bonds.

Investment Risks

Yields on municipal securities depend on a variety of factors, including: the
general conditions of the money market and the taxable and municipal bond
markets; the size of the particular offering; the maturity of the obligations;
and the rating of the issue. The ability of the Trust to achieve its investment
objective also depends on the continuing ability of the issuers of municipal
securities and participation interests, or the guarantors of either, to meet
their obligations for the payment of interest and principal when due.

Investment Limitations
The Trust will not:


 .  Invest more than 5% of its total assets in securities of one issuer (except
   cash and cash items and U.S. government obligations); or


 .  borrow money or pledge securities except, under certain circumstances, the
   Trust may borrow up to one-third of the value of its total assets and pledge
   up to 10% of the value of those assets to secure such borrowings.

The above investment limitations cannot be changed without shareholder approval.
The following limitations, however, can be changed by the Trustees without
shareholder approval. Shareholders will be notified before any material change
in these limitations becomes effective.

The Trust will not:

 .  Commit more than 15% of its net assets to illiquid obligations; or

 .  invest more than 5% of its total assets in industrial development bonds of
   issuers that have a record of less than three years of continuous operations.

                               TRUST INFORMATION

Management of the Trust
Board of Trustees

The Trust is managed by a Board of Trustees. The Trustees are responsible for
managing the Trust's business affairs and for exercising all the Trust's powers
except those reserved for the shareholders. The Executive Committee of the Board
of Trustees handles the Board's responsibilities between meetings of the Board.

Investment Adviser

Investment decisions for the Trust are made by Federated Management, the Trust's
investment adviser (the "Adviser"), subject to direction by the Trustees. The
Adviser continually conducts investment research and supervision for the Trust
and is responsible for the purchase or sale of portfolio instruments, for which
it receives an annual fee from the Trust.

Advisory Fees

 The Trust's Adviser receives an annual investment advisory fee equal to 0.40%
 of the Trust's average daily net assets. Under the investment advisory
 contract, the Adviser will reimburse the Trust the amount, limited to the
 amount of the advisory fee, by which the Trust's aggregate annual operating
 expenses, including its investment advisory fee, but excluding interest, taxes,
 brokerage commissions, expenses of registering and qualifying the Trust and its
 shares under federal and state laws and regulations, expenses of withholding
 taxes, and extraordinary expenses, exceed 0.45% of its average daily net
 assets. Any accrued shareholder services fees and/or distribution plan fees are
 considered to be outside this contractual expense limitation. Further, the
 limitation does not include reimbursement to the Trust of any expenses incurred
 by shareholders who use the transfer agent's subaccounting facilities.


Adviser's Background

 Federated Management, a Delaware business trust organized on April 11, 1989, is
 a registered investment adviser under the Investment Advisers Act of 1940. It
 is a subsidiary of Federated Investors, Inc. All of the Class A (voting) shares
 of Federated Investors, Inc. are owned by a trust, the trustees of which are
 John F. Donahue, Chairman and Director of Federated Investors, Inc., Mr.
 Donahue's wife, and Mr. Donahue's son, J. Christopher Donahue, who is President
 and Director of Federated Investors, Inc.


Federated Management and other subsidiaries of Federated Investors, Inc. serve
as investment advisers to a number of investment companies and private accounts.
Certain other subsidiaries also provide administrative services to a number of
investment companies. With over $120 billion invested across more than 300 funds
under management and/or administration by its subsidiaries, as of December 31,
1997, Federated Investors, Inc. is one of the largest mutual fund investment
managers in the United States. With more than 2,000 employees, Federated
continues to be led by the management who founded the company in 1955. Federated
funds are presently at work in and through approximately 4,000 financial
institutions nationwide.

Both the Trust and the Adviser have adopted strict codes of ethics governing the
conduct of all employees who manage the Trust and its portfolio securities.
These codes recognize that such persons owe a fiduciary duty to the Trust's
shareholders and must place the interests of shareholders ahead of the
employees' own interest. Among other things, the codes: require preclearance and
periodic reporting of personal securities transactions; prohibit personal
transactions in securities being purchased or sold, or being considered for
purchase or sale, by the Trust; prohibit purchasing securities in initial public
offerings; and prohibit taking profits on securities held for less than sixty
days. Violations of the codes are subject to review by the Trustees and could
result in severe penalties.


Jeff A. Kozemchak has been the Trust's portfolio manager since June 1996. Mr.
Kozemchak joined Federated Investors, Inc. or its predecessor in 1987 and has

Distribution of Institutional Service Shares

Federated Securities Corp. is the principal distributor for Institutional
Service Shares. It is a Pennsylvania corporation organized on November 14, 1969,
and is the principal distributor for a number of investment companies. Federated
Securities Corp. is a subsidiary of Federated Investors, Inc.


Distribution Plan and Shareholder Services

Under a distribution plan adopted in accordance with Rule 12b-1 under the
Investment Company Act of 1940 (the "Plan"), the distributor may be paid a fee
by the Trust in an amount computed at an annual rate of up to 0.25% of the
average daily net asset value of the Shares. The distributor may select
financial institutions such as banks, fiduciaries, custodians for public funds,
investment advisers, and broker/dealers to provide sales services or
distribution-related support services as agents for their clients or customers.

The Plan is a compensation-type plan. As such, the Trust makes no payments to
the distributor except as described above. Therefore, the Trust does not pay for
unreimbursed expenses of the distributor, including amounts expended by the
distributor in excess of amounts received by it from the Trust, interest,
carrying, or other financing charges in connection with excess amounts expended,
or the distributor's overhead expenses. However, the distributor may be able to
recover such amounts or may earn a profit from future payments made by the Trust
under the Plan.


In addition, the Trust has entered into a Shareholder Services Agreement with
Federated Shareholder Services, a subsidiary of Federated Investors, Inc., under
which the Trust may make payments up to 0.25% of the average daily net asset
value of its shares to obtain certain personal services for shareholders and to
maintain shareholder accounts. From time to time and for such periods as deemed
appropriate, the amount stated above may be reduced voluntarily. Under the
Shareholder Services Agreement, Federated Shareholder Services will either
perform shareholder services directly or will select financial institutions to
perform shareholder services. Financial institutions will receive fees based
upon shares owned by their clients or customers. The schedules of such fees and
the basis upon which fees will be paid will be determined from time to time by
the Trust and Federated Shareholder Services.


Supplemental Payments to Financial Institutions

In addition to payments made pursuant to the Distribution Plan and Shareholder
Services Agreement, Federated Securities Corp. and Federated Shareholder
Services, from their own assets, may pay financial institutions supplemental
fees for the performance of substantial sales services, distribution-related
support services, or shareholder services. The support may include sponsoring
sales, educational and training seminars for their employees, providing sales
literature, and engineering computer software programs that emphasize the
attributes of the Trust. Such assistance will be predicated upon the amount of
shares the financial institution sells or may sell, and/or upon the type and
nature of sales or marketing support furnished by the financial institution. Any
payments made by the distributor may be reimbursed by the Adviser or its
affiliates.

Administration of the Trust
Administrative Services

Federated Services Company, a subsidiary of Federated Investors, Inc., provides
administrative personnel and services (including certain legal and financial
reporting services) necessary to operate the Trust. Federated Services Company
provides these at an annual rate which relates to the average aggregate daily
net assets of all funds advised by subsidiaries of Federated Investors, Inc.
("Federated Funds") as specified below:

Maximum               Average Aggregate
  Fee                 Daily Net Assets

0.150%           on the first $250 million
0.125%           on the next $250 million
0.100%           on the next $250 million
0.075%     on assets in excess of $750 million

The administrative fee received during any fiscal year shall be at least
$125,000 per portfolio and $30,000 per each additional class of shares.
Federated Services Company may choose voluntarily to waive a portion of its fee.

                                NET ASSET VALUE

The Trust's net asset value per Share fluctuates. The net asset value for Shares
is determined by adding the interest of the Shares in the market value of all
securities and other assets of the Trust, subtracting the interest of the Shares
in the liabilities of the Trust and those attributable to Shares, and dividing
the remainder by the total number of Shares outstanding. The net asset value for
Shares may differ from that of Institutional Shares due to the variance in daily
net income realized by each class. Such variance will reflect only accrued net
income to which the shareholders of a particular class are entitled.

                   INVESTING IN INSTITUTIONAL SERVICE SHARES

Share Purchases

Shares are sold on days on which the New York Stock Exchange and the Federal
Reserve wire system are open for business. Shares may be purchased either by
wire or by mail.

To purchase Shares, open an account by calling Federated Securities Corp.
Information needed to establish the account will be taken over the telephone.
The Trust reserves the right to reject any purchase request.

By Wire

To purchase Shares by Federal Reserve wire, call the Trust before 4:00 p.m.
(Eastern time) to place an order. The order is considered received immediately.
Payment by federal funds must be received before 3:00 p.m. (Eastern time) on the
next business day following the order. Federal funds should be wired as follows:
Federated Shareholder Services Company, c/o State Street Bank and Trust Company,
Boston, Massachusetts; Attention: EDGEWIRE; For Credit to: Federated Short-Term
Municipal Trust--Institutional Service Shares; Trust Number (this number can be
found on the account statement or by contacting the Trust); Group Number or Wire
Order Number; Nominee or Institution Name; and ABA Number 011000028. Shares
cannot be purchased on days on which the New York Stock Exchange is closed and
on federal holidays restricting wire transfers. Questions on wire purchases
should be directed to your shareholder services representative at the telephone
number listed on your account statement.

By Mail

To purchase Shares by mail, send a check made payable to Federated Short-Term
Municipal Trust--Institutional Service Shares to: Federated Shareholder Services
Company, P.O. Box 8600, Boston, Massachusetts 02266-8600. Orders by mail are
considered received when payment by check is converted into federal funds. This
is normally the next business day after the check is received.

Minimum Investment Required

The minimum initial investment in Shares is $25,000 plus any financial
intermediary's fee, if applicable. However, an account may be opened with a
smaller amount as long as the $25,000 minimum is reached within 90 days. The
minimum investment for an institutional investor will be calculated by combining
all accounts it maintains with the Trust. Accounts established through a
financial intermediary may be subject to a smaller minimum investment.

What Shares Cost

Shares are sold at their net asset value next determined after an order is
received. There is no sales charge imposed by the Trust. Investors who purchase
Shares through a financial intermediary may be charged an additional service fee
by that financial intermediary.


The net asset value is determined as of the close of trading (normally 4:00
p.m., Eastern time) on the New York Stock Exchange Monday through Friday, except
on (i) days on which there are not sufficient changes in the value of the
Trust's portfolio securities that its net asset value might be materially
affected; (ii) days during which no Shares are tendered for redemption and no
orders to purchase Shares are received; or (iii) the following holidays: New
Year's Day, Martin Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial
Day, Independence Day, Labor Day, Thanksgiving Day, and Christmas Day.

Confirmations and Account Statements

SHAREHOLDERS WILL RECEIVE DETAILED CONFIRMATIONS OF TRANSACTIONS. IN ADDITION,
SHAREHOLDERS WILL RECEIVE PERIODIC STATEMENTS REPORTING ALL ACCOUNT ACTIVITY,
INCLUDING DIVIDENDS PAID. THE TRUST WILL NOT ISSUE SHARE CERTIFICATES.


Dividends

Dividends are declared daily and paid monthly. Dividends are declared just prior
to determining net asset value. If an order for Shares is placed on the
preceding business day, Shares purchased by wire begin earning dividends on the
business day wire payment is received by State Street Bank. If the order for
Shares and payment by wire are received on the same day, Shares begin earning
dividends on the next business day. Shares purchased by check begin earning
dividends on the business day after the check is converted, upon instruction of
the transfer agent, into federal funds. Dividends are automatically reinvested
in additional Shares unless cash payments are requested by contacting the Trust.

Capital Gains

Distributions of net realized long-term capital gains realized by the Trust, if
any, will be made at least annually.

                     REDEEMING INSTITUTIONAL SERVICE SHARES

The Trust redeems Shares at their net asset value next determined after the
Trust receives the redemption request. Investors who redeem Shares through a
financial intermediary may be charged a service fee by that financial
intermediary. Redemptions may be made on days on which the Trust computes its
net asset value. Redemption requests must be received in proper form and can be
made by telephone request or by written request.

Telephone Redemption

Shareholders may redeem their Shares by telephoning the Trust before 4:00 p.m.
(Eastern time). The proceeds will normally be wired the following business day,
but in no event more than seven days, to the shareholder's account at a domestic
commercial bank that is a member of the Federal Reserve System. If at any time
the Trust shall determine it necessary to terminate or modify this method of
redemption, shareholders would be promptly notified.

An authorization form permitting the Trust to accept telephone requests must
first be completed. It is recommended that investors request this privilege at
the time of their initial application. If not completed at the time of initial
application, authorization forms and information on this service can be obtained
through Federated Securities Corp. Telephone redemption instructions may be
recorded. If reasonable procedures are not followed by the Trust, it may be
liable for losses due to unauthorized or fraudulent telephone instructions.

In the event of drastic economic or market changes, a shareholder may experience
difficulty in redeeming by telephone. If such a case should occur, another
method of redemption, such as "Written Requests," should be considered.

Written Requests

Shares may also be redeemed by sending a written request to Federated
Shareholder Services Company, P.O. Box 8600, Boston, Massachusetts 02266-8600.
Call the Trust for specific instructions before redeeming by letter. The
shareholder will be asked to provide in the request his name, the Trust name and
class of shares, his account number, and the share or dollar amount requested.
If Share certificates have been issued, they should be sent unendorsed with the
written request by registered or certified mail to the address noted above.

Signatures

Shareholders requesting a redemption of any amount to be sent to an address
other than that on record with the Trust, or a redemption payable other than to
the shareholder of record must have their signatures guaranteed by:

 .  a trust company or commercial bank whose deposits are insured by the Bank
   Insurance Fund, which is administered by the Federal Deposit Insurance
   Corporation ("FDIC");

 .  a member of the New York, American, Boston, Midwest, or Pacific Stock
   Exchange;

 .  a savings bank or savings association whose deposits are insured by the
   Savings Association Insurance Fund, which is administered by the FDIC; or

 .  any other "eligible guarantor institution" as defined in the Securities
   Exchange Act of 1934, as amended.

The Trust does not accept signatures guaranteed by a notary public.

The Trust and its transfer agent have adopted standards for accepting signature
guarantees from the above institutions. The Trust may elect in the future to
limit eligible signature guarantors to institutions that are members of a
signature guarantee program. The Trust and its transfer agent reserve the right
to amend these standards at any time without notice.

Receiving Payment

Normally, a check for the proceeds is mailed within one business day, but in no
event more than seven days, after receipt of a proper written redemption
request.

Accounts with Low Balances

Due to the high cost of maintaining accounts with low balances, the Trust may
redeem Shares in any account and pay the proceeds to the shareholder if the
account balance falls below a required minimum value of $25,000 due to
shareholder redemptions. This requirement does not apply, however, if the
balance falls below $25,000 because of changes in the Trust's net asset value.
Before Shares are redeemed to close an account, the shareholder is notified in
writing and allowed 30 days to purchase additional Shares to meet the minimum
requirement.

                            SHAREHOLDER INFORMATION

Voting Rights

Each Share of the Trust gives the shareholder one vote in Trustee elections and
other matters submitted to shareholders for vote. All shares of all classes of
each portfolio in the Trust have equal voting rights except that in matters
affecting only a particular portfolio or class only shares of that portfolio or
class are entitled to vote. As a Massachusetts business trust, the Trust is not
required to hold annual shareholder meetings. Shareholder approval will be
sought only for certain changes in the Trust's operation and for the election of
Trustees under certain circumstances.

Trustees may be removed by the Trustees or by shareholders at a special meeting.
A special meeting of shareholders shall be called for this purpose by the
Trustees upon written request of shareholders owning at least 10% of the
outstanding shares of the Trust entitled to vote.

                                TAX INFORMATION

Federal Income Tax

The Trust will pay no federal income tax because it expects to meet requirements
of the Internal Revenue Code of 1986, as amended, applicable to regulated
investment companies and to receive the special tax treatment afforded to such
companies.

Shareholders are not required to pay the federal regular income tax on any
dividends received from the Trust that represent net interest on tax-exempt
municipal bonds. However, dividends representing net interest earned on some
municipal bonds may be included in calculating the federal individual
alternative minimum tax or the federal alternative minimum tax for corporations.

The alternative minimum tax, equal to up to 28% of alternative minimum taxable
income for individuals and 20% for corporations, applies when it exceeds the
regular tax for the taxable year. Alternative minimum taxable income is equal to
the regular taxable income of the taxpayer increased by certain "tax preference"
items not included in regular taxable income and reduced by only a portion of
the deductions allowed in the calculation of the regular tax.

Interest on certain "private activity" bonds issued after August 7, 1986, is
treated as a tax preference item for both individuals and corporations. Unlike
traditional governmental purpose municipal bonds, which finance roads, schools,
libraries, prisons and other public facilities, private activity bonds provide
benefits to private parties. The Trust may purchase all types of municipal
bonds, including private activity bonds. Thus, while the Trust has no present
intention of purchasing any private activity bonds, should it purchase any such
bonds, a portion of the Trust's dividends may be treated as a tax preference
item.

In addition, in the case of a corporate shareholder, dividends of the Trust
which represent interest on municipal bonds may be subject to the 20% corporate
alternative minimum tax because the dividends are included in a corporation's
"adjusted current earnings." The corporate alternative minimum tax treats 75% of
the excess of a taxpayer's pre-tax "adjusted current earnings" over the
taxpayer's alternative minimum taxable income as a tax preference item.
"Adjusted current earnings" is based upon the concept of a corporation's
"earnings and profits." Since "earnings and profits" generally includes the full
amount of any Trust dividend, and alternative minimum taxable income does not
include the portion of the Trust's dividend attributable to municipal bonds
which are not private activity bonds, the difference will be included in the
calculation of the corporation's alternative minimum tax.

Dividends of the Trust representing net interest income earned on some temporary
investments and any realized net short-term gains are taxed as ordinary income.

These tax consequences apply whether dividends are received in cash or as
additional Shares. Information on the tax status of dividends and distributions
is provided annually.

State and Local Taxes

Because interest received by the Trust may not be exempt from all state and
local income taxes, shareholders may be required to pay state and local taxes on
dividends received from the Trust.

Shareholders are urged to consult their own tax advisers regarding the status of
their accounts under state and local tax laws.


                            PERFORMANCE INFORMATION

From time to time the Trust advertises its total return, yield, and tax-
equivalent yield for Institutional Service Shares.

TOTAL RETURN REPRESENTS THE CHANGE, OVER A SPECIFIC PERIOD OF TIME, IN THE VALUE
OF AN INVESTMENT IN SHARES OF THE TRUST AFTER REINVESTING ALL INCOME AND CAPITAL
GAIN DISTRIBUTIONS. IT IS CALCULATED BY DIVIDING THAT CHANGE BY THE INITIAL
INVESTMENT AND IS EXPRESSED AS A PERCENTAGE.

The yield of Shares of the Trust is calculated by dividing the net investment
income per share (as defined by the Securities and Exchange Commission) earned
by Shares over a thirty-day period by the maximum offering price per share of
Shares on the last day of the period. This number is then annualized using
semi-annual compounding. The tax-equivalent yield of Shares is calculated
similarly to the yield, but is adjusted to reflect the taxable yield that Shares
would have had to earn to equal its actual yield, assuming a specific tax rate.
The yield and the tax-equivalent yield do not necessarily reflect income
actually earned by Shares and, therefore, may not correlate to the dividends or
other distributions paid to shareholders.

The Trust is sold without any sales charge or other similar non-recurring
charges.

Total return, yield, and tax-equivalent yield will be calculated separately for
Shares and Institutional Shares.

From time to time, advertisements for the Trust may refer to ratings, rankings
and other information in certain financial publications and/or compare the
Trust's performance to certain indices.

                            OTHER CLASSES OF SHARES

The Trust also offers another class of shares called Institutional Shares.

Institutional Shares are sold primarily to accounts for which financial
institutions act in a fiduciary or agency capacity, or other accounts where the
financial institution maintains master accounts with an aggregate investment of
at least $400 million in certain funds which are advised or distributed by
affiliates of Federated Investors, Inc.

Institutional Service Shares and Institutional Shares are subject to certain of
the same expenses; however, Institutional Shares are sold at net asset value,
distributed without a 12b-1 Plan, and are subject to a minimum initial
investment of $25,000. Expense differences between Institutional Service Shares
and Institutional Shares may affect the performance of each class.

Financial institutions and brokers providing sales and/or administrative
services may receive different compensation depending upon which class of shares
of the Trust is sold.

The stated advisory fee is the same for both classes of shares.

To obtain more information and a prospectus for Institutional Shares, investors
may call 1-800-341-7400.

                         NOTES TO FINANCIAL STATEMENTS

                      FEDERATED SHORT-TERM MUNICIPAL TRUST
                                 JUNE 30, 1998

Organization

Federated Short-Term Municipal Trust (the "Trust") is registered under the
Investment Company Act of 1940, as amended (the "Act"), as a diversified,
open-end management investment company. The Trust offers two classes of shares:
Institutional Shares and Institutional Service Shares. The investment objective
of the Trust is to provide dividend income which is exempt from federal regular
income tax. The Trust pursues this investment objective by investing in a
portfolio of municipal securities with a dollar-weighted average maturity of
less than three years.

Significant Accounting Policies

The following is a summary of significant accounting policies consistently
followed by the Trust in the preparation of its financial statements. These
policies are in conformity with generally accepted accounting principles.

Investment Valuations

Municipal bonds are valued by an independent pricing service, taking into
consideration yield, liquidity, risk, credit quality, coupon, maturity, type of
issue, and any other factors or market data the pricing service deems relevant.
Short-term securities are valued at the prices provided by an independent
pricing service. However, short-term securities with remaining maturities of
sixty days or less at the time of purchase may be valued at amortized cost,
which approximates fair market value.

Investment Income, Expenses and Distributions

Interest income and expenses are accrued daily. Bond premium and discount, if
applicable, are amortized as required by the Internal Revenue Code, as amended
(the "Code"). Distributions to shareholders are recorded on the ex-dividend
date.

Income and capital gain distributions are determined in accordance with income
tax regulations which may differ from generally accepted accounting principles.
These differences are primarily due to expired capital loss carryforwards. The
following reclassification has been made to the financial statements.

        Increase (Decrease)
                   Accumulated Net
Paid In Capital  Realized Gain (Loss)
 ($1,720,574)         $1,720,574

Federal Taxes

It is the Trust's policy to comply with the provisions of the Code applicable to
regulated investment companies and to distribute to shareholders each year
substantially all of its income. Accordingly, no provisions for federal tax are
necessary.

At June 30, 1998, the Trust, for federal tax purposes, had a capital loss
carryforward of $4,030,794 which will reduce the Trust's taxable income arising
from future net realized gain on investments, if any, to the extent permitted by
the Code, and thus will reduce the amount of the distributions to shareholders
which would otherwise be necessary to relieve the Trust of any liability for
federal tax. Pursuant to the Code, such capital loss carryforward will expire as
follows:

<TABLE>

Expiration Year                  Expiration Amount
<S>                              <C>

2001                               $   62,121
2003                               $1,189,491
2004                               $2,597,123
2005                               $  170,193

When-Issued and Delayed Delivery Transactions
</TABLE>

The Trust may engage in when-issued or delayed delivery transactions. The Trust
records when-issued securities on the trade date and maintains security
positions such that sufficient liquid assets will be available to make payment
for the securities purchased. Securities purchased on a when-issued or delayed
delivery basis are marked to market daily and begin earning interest on the
settlement date.

Use of Estimates

The preparation of financial statements in conformity with generally accepted
accounting principles requires management to make estimates and assumptions that
affect the amounts of assets, liabilities, expenses and revenues reported in the
financial statements. Actual results could differ from those estimated.

Other
Investment transactions are accounted for on the trade date.

Shares of Beneficial Interest
The Declaration of Trust permits the Trustees to issue an unlimited number of
full and fractional shares of beneficial interest (without par value) for each
class of shares.

Transactions in shares were as follows:

Investment Advisory Fee and Other Transactions with Affiliates
Investment Advisory Fee

Federated Management, the Trust's investment adviser (the "Adviser"), receives
for its services an annual investment advisory fee equal to 0.40% of the Trust's
average daily net assets. The Adviser will waive, to the extent of its advisory
fee, the amount, if any, by which the Trust's aggregate annual operating
expenses (excluding interest, taxes, brokerage commissions, expenses of
registering and qualifying the Trust and its shares under federal and state laws
and regulations, expenses of withholding taxes, and extraordinary expenses)
exceed 0.45% of average daily net assets of the Trust.

Administrative Fee

Federated Services Company ("FServ"), under the Administrative Services
Agreement, provides the Trust with administrative personnel and services. The
fee paid to FServ is based on the level of average aggregate daily net assets of
all funds advised by subsidiaries of Federated Investors, Inc. for the period.
The administrative fee received during the period of the Administrative Services
Agreement shall be at least $125,000 per portfolio and $30,000 per each
additional class of shares.

Distribution Services Fee

The Trust has adopted a Distribution Plan (the "Plan") pursuant to Rule 12b-1
under the Act. Under the terms of the Plan, the Trust will compensate Federated
Securities Corp. ("FSC"), the principal distributor, from the net assets of the
Trust to finance activities intended to result in the sale of the Trust's
Institutional Service Shares. The Plan provides that the Trust may incur
distribution expenses of up to 0.25% of the average daily net assets of the
Institutional Service Shares, annually, to compensate FSC. The distributor may
voluntarily choose to waive any portion of its fee. The distributor can modify
or terminate this voluntary waiver at any time at its sole discretion.

Shareholder Services Fee

Under the terms of a Shareholder Services Agreement with Federated Shareholder
Services ("FSS"), the Trust will pay FSS up to 0.25% of average daily net assets
of the Trust for the period. The fee paid to FSS is used to finance certain
services for shareholders and to maintain shareholder accounts. FSS may
voluntarily choose to waive any portion of its fee. FSS can modify or terminate
this voluntary waiver at any time at its sole discretion.

Transfer and Dividend Disbursing Agent Fees and Expenses

FServ, through its subsidiary, Federated Shareholder Services Company ("FSSC")
serves as transfer and dividend disbursing agent for the Trust. The fee paid to
FSSC is based on the size, type, and number of accounts and transactions made by
shareholders.

Portfolio Accounting Fees

FServ maintains the Trust's accounting records for which it receives a fee. The
fee is based on the level of the Trust's average daily net assets for the
period, plus out-of-pocket expenses.

General

Certain of the Officers and Trustees of the Trust are Officers and Directors or
Trustees of the above companies.

Year 2000 (unaudited)

Similar to other financial organizations, the Trust could be adversely affected
if the computer systems used by the Trust's service providers do not properly
process and calculate date-related information and data from and after January
1, 2000. The Trust's Adviser and Administrator are taking measures that they
believe are reasonably designed to address the Year 2000 issue with respect to
computer systems that they use and to obtain reasonable assurances that
comparable steps are being taken by each of the Trust's other service providers.
At this time, however, there can be no assurance that these steps will be
sufficient to avoid any adverse impact to the Trust.

Investment Transactions

Purchases and sales of investments, excluding short-term securities, for the
period ended June 30, 1998, were as follows:

Purchases         $64,894,259
Sales             $93,851,888

                   REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Shareholders and Board of Trustees of
FEDERATED SHORT-TERM MUNICIPAL TRUST

We have audited the accompanying statement of assets and liabilities of
Federated Short-Term Municipal Trust (a Massachusetts business trust), including
the schedule of portfolio of investments as of June 30, 1998, and the related
statement of operations for the year then ended, the statement of changes in net
assets for each of the two years in the period then ended, and the financial
highlights (see pages 2 and 12 of the prospectus) for each of the periods
presented. These financial statements and financial highlights are the
responsibility of the Trust's management. Our responsibility is to express an
opinion on these financial statements and financial highlights based on our
audits. We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of securities owned as of June
30, 1998, by corespndence with the custodian. An audit also includes assessing
the accounting principles used and significant estimates made by management, as
well as evaluating the overall financial statement presentation. We believe that
our audits provide a reasonable basis for our opinion. In our opinion, the
financial statements and financial highlights referred to above present fairly,
in all material respects, the financial position of Federated Short-Term
Municipal Trust as of June 30, 1998, the results of its operations for the year
then ended, the changes in its net assets for each of the two years in the
period then ended, and the financial highlights for the periods presented, in
conformity with generally accepted accounting principles.
