PROSPECTUS



   



The shares of Federated Municipal Opportunities Fund, Inc. (the "Fund")

represent interests in a diversified, open-end, management investment

company (a mutual fund) that seeks a high level of current income exempt from

the federal regular income tax by investing primarily in a professionally

managed, diversified portfolio of municipal bonds.



    



THE SHARES OFFERED BY THIS PROSPECTUS ARE NOT DEPOSITS OR OBLIGATIONS OF ANY
BANK, ARE NOT ENDORSED OR GUARANTEED BY ANY BANK, AND ARE NOT INSURED BY THE
FEDERAL DEPOSIT INSURANCE CORPORATION, THE FEDERAL RESERVE BOARD, OR ANY OTHER

INCLUDING THE POSSIBLE LOSS OF PRINCIPAL.



This prospectus contains the information you should read and know before you

invest in Class A Shares, Class B Shares, and Class C Shares of the Fund.

Keep this prospectus for future reference.



THE FUND MAY INVEST PRIMARILY IN LOWER RATED MUNICIPAL BONDS, COMMONLY REFERRED
TO AS "JUNK BONDS." INVESTMENTS OF THIS TYPE ARE SUBJECT TO A GREATER RISK OF
LOSS OF PRINCIPAL AND INTEREST THAN INVESTMENTS IN HIGHER RATED MUNICIPAL
SECURITIES. PURCHASERS SHOULD CAREFULLY ASSESS THE RISKS ASSOCIATED WITH AN
INVESTMENT IN THIS FUND.



The Fund's investment adviser will endeavor to limit these risks through

diversifying the portfolio and through careful credit analysis of individual

issuers.

12b-1 fee during the fiscal year ending August 31, 1999. If the Fund was

paying or accruing the 12b-1 fee, the Fund would be able to pay up to 0.25%

of its average daily net assets for the 12b-1 fee. See "Fund Information."

Long-term shareholders may pay more than the economic equivalent of the

maximum front-end sales charges permitted under the rules of the National

Association of Securities Dealers, Inc.

(3) The contingent deferred sales charge is 5.50% in the first year declining

to 1.00% in the sixth year and 0.00% thereafter. (See "Investing in the

Fund" and "Contingent Deferred Sales Charge.")

(4) Class B Shares convert to Class A Shares (which pay lower ongoing

expenses) approximately eight years after purchase. (See "Conversion of

Class B Shares.")

(5) The contingent deferred sales charge assessed is 1.00% of the lesser of

the original purchase price or the net asset value of shares redeemed within

one year of their purchase date.

The purpose of this table is to assist an investor in understanding the

various costs and expenses that a shareholder of the Fund will bear either

directly or indirectly. For more complete descriptions of the various costs

GENERAL INFORMATION



   



The Fund was incorporated under the laws of the State of Maryland on

November 26, 1986. Shares of the Fund are offered in four classes of shares

known as Class A Shares, Class B Shares, Class C Shares, and Class F Shares

which represent interests in a single portfolio of securities. The Fund is

designed for individuals as a convenient means of accumulating an interest in

a professionally managed, diversified portfolio of high income municipal

bonds. This prospectus relates to Class A Shares, Class B Shares, and Class C

Shares ("Shares") of the Fund.



    



The Fund's current net asset value and offering price may be found in the

mutual funds section of local newspapers under "Federated" and the

appropriate class designation listing.

YEAR 2000 STATEMENT



   



Like other mutual funds and business organizations worldwide, the Fund'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 Fund 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 Fund's operations.



    



INVESTMENT INFORMATION



INVESTMENT OBJECTIVE



The investment objective of the Fund is to provide a high level of current

income which is generally exempt from the federal regular income tax (federal

regular income tax does not include the federal alternative minimum tax). The

investment objective cannot be changed without approval of shareholders.

While there is no assurance that the Fund will achieve its investment

objective, it endeavors to do so by following the investment policies

described in this prospectus.



   



The Fund pursues its investment objective by investing primarily in a

diversified portfolio of municipal bonds. As a matter of fundamental policy,

the Fund invests its assets so that at least 80% of its annual interest

income is exempt from federal regular income tax. As a matter of non-

fundamental policy, under normal circumstances, the Fund will invest

primarily in lower quality municipal bonds. These bonds will usually offer

higher yields than higher rated bonds but involve greater investment risk at

the time of issue. (See "Investment Risks.")



    



INVESTMENT POLICIES



Unless otherwise designated, the investment policies described below may be

changed by the Directors without shareholder approval. Shareholders will be

notified before any material change in these policies becomes effective.



ACCEPTABLE INVESTMENTS



   



Municipal bonds are debt obligations issued by or on behalf of states,

territories, and possessions of the United States, including the District of

Columbia, and their political subdivisions, agencies and instrumentalities,

the interest from which is exempt from the federal regular income tax. It is

likely, however, that shareholders will be required to include interest from

a portion of the municipal bonds owned by the Fund in calculating the federal

individual alternative minimum tax or the federal alternative minimum tax for

corporations.



    



CHARACTERISTICS



The municipal bonds in which the Fund generally invests are rated Baa or

lower by Moody's Investors Service, Inc. ("Moody's") or rated BBB or lower by

Standard & Poor's ("S&P"). The Fund may buy bonds which are unrated but which

the adviser judges to be similar in quality to those rated bonds which it

purchases. (See "High Yield Securities.") A description of the ratings

categories is contained in the Appendix to this prospectus.



   



The Fund may invest any or all of its assets in higher quality tax-exempt

securities when the difference in returns between those securities and lower

quality securities is very narrow or when the adviser expects increased

volatility in interest rates. This may reduce the Fund's current income.



    



WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS



The Fund may purchase securities on a when-issued or delayed delivery basis.

These transactions are arrangements in which the Fund purchases securities

with payment and delivery scheduled for a future time. The seller's failure to

complete these transactions may cause the Fund 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 Fund may dispose of a commitment prior to settlement if the adviser deems

it appropriate to do so. In addition, the Fund 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 Fund may realize short-term profits or losses upon the sale

of such commitments.



INVERSE FLOATERS



The Fund may invest in securities known as "inverse floaters" which represent

interests in municipal securities. The Fund intends to purchase inverse

floaters to assist in duration management and to seek current income. 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 Fund 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 Fund may not purchase or sell futures contracts if immediately

thereafter the sum of the amount of margin deposits on the Fund's existing

futures positions would exceed 5% of the market value of the Fund's total

assets. When the Fund 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 Fund's custodian (or the broker,

if legally permitted) to collateralize the position.



RISKS



When the Fund 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 Fund's portfolio. This may cause the

futures contract to react differently than the portfolio securities to market

changes. In addition, the Fund'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 Fund 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 Fund's

ability to establish and close out futures positions depends on this

secondary market.



TEMPORARY INVESTMENTS



The Fund invests its assets so that at least 80% of its annual interest income

is exempt from the federal regular income tax, except when investing for

"defensive" purposes as described below. This policy cannot be changed

without approval of shareholders. From time to time on a temporary basis, or

when the investment adviser determines that market conditions call for a

temporary defensive posture, the Fund may invest all of its assets in higher

quality tax-exempt or taxable temporary investments. These temporary

investments include: fixed or variable rate notes issued by or on behalf of

municipal or corporate issuers; obligations issued or guaranteed by the

U.S. government, its agencies or instrumentalities; other debt securities;

commercial paper; certificates of deposit of banks; and repurchase agreements

(arrangements in which the organization selling the Fund a bond or temporary

investment 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.

However, the investment adviser will limit temporary investments to those it

considers to be of good quality.



OTHER INVESTMENT TECHNIQUES



The Fund may purchase a right to sell a security held by it back to the issuer

or to another party at an agreed upon price at any time during a stated period

or on a certain date. These rights may be referred to as "liquidity puts" or

"standby commitments."



The Fund may also hedge all or a portion of its investments by entering into

futures contracts or options on them. Any gains realized on futures contracts

and options thereon are taxable. The Fund will notify shareholders before it

engages in these futures transactions.



PORTFOLIO TURNOVER



Although the Fund does not intend to invest for the purpose of seeking short-

term profits, securities in its portfolio will be sold whenever the Fund's

investment adviser believes it is appropriate to do so in light of the Fund's

investment objective, without regard to the length of time a particular

security may have been held.



MUNICIPAL BONDS



Municipal bonds are generally issued to finance public works such as

airports, bridges, highways, housing, hospitals, mass transportation

projects, schools, streets, and water and sewer works. Municipal bonds are

also issued to repay outstanding obligations, to raise funds for general

operating expenses, and to make loans to other public institutions and

facilities. Certain types of "private activity" municipal bonds are issued to

obtain funding for privately operated facilities.



There are two categories of municipal bonds: general obligation and revenue.

General obligation bonds are backed by the taxing power of the issuing

municipality. Revenue bonds are backed by the revenues of a project or

facility. Payment of principal and interest on such bonds is dependent solely

on the revenue generated by the facility financed by the bond or other

specified sources of revenue or collateral. Private activity bonds are

typically one type of "revenue" bonds.



In most cases, lower quality bonds are private activity bonds or other

revenue bonds which are not payable from general tax revenues. The Fund may

invest more than 25% of the value of its assets in private activity bonds

which may result in more than 25% of the Fund's assets being invested in one

industry. It is also possible that the Fund may from time to time invest more

than 25% of its assets in health care facilities revenue obligations, housing

agency revenue obligations or electric utility obligations. Economic,

business, political and other developments generally affecting the revenues

of issuers in such a market segment (for example, proposed legislation or

pending court decisions affecting the financing of projects and market

factors affecting the demand for their services or products) may have a

general adverse impact on all municipal bonds in the segment.



The Fund does not intend to purchase securities if, as a result of such

purchase, more than 25% of the value of its total assets would be invested in

the securities of governmental subdivisions located in any one state,

territory or possession of the United States.



INVESTMENT RISKS



The value of Shares will fluctuate. The amount of this fluctuation is

dependent upon the quality and maturity of the municipal bonds in the Fund's

portfolio as well as on market conditions. Generally speaking, the lower

quality, long-term bonds in which the Fund invests have greater fluctuation

in value than high quality, shorter-term bonds.



Municipal bond prices are interest rate sensitive, which means that their

value varies inversely with market interest rates. Thus, if market interest

rates have increased from the time a bond was purchased, the bond, if sold,

might be sold at a price less than its cost. Similarly, if market interest

rates have declined from the time a bond was purchased, the bond, if sold,

might be sold at a price greater than its cost. (In either instance, if the

bond was held to maturity, no loss or gain normally would be realized as a

result of interim market fluctuations.)



Prices of lower grade bonds also fluctuate with changes in the perceived

quality of the credit of their issuers. Consequently, shares may not be

suitable for persons who cannot assume the somewhat greater risks of capital

depreciation associated with higher tax-exempt income yields. In addition,

lower grade bonds have speculative characteristics. Changes in economic

conditions or other circumstances are more likely to lead to weakened

capacity to make principal and interest payments than higher rated bonds.



A large portion of the Fund's portfolio may be invested in bonds whose

interest payments are from revenues of similar projects (such as housing or

hospitals) or where issuers share the same geographic location. As a result,

the Fund may be more susceptible to similar economic, political or regulatory

developments than would a portfolio of bonds with a greater geographic and

project variety. This susceptibility may result in greater fluctuations in

share price.



Many issuers of municipal bonds which have characteristics of rated bonds

choose to not have their obligations rated. Unrated bonds may carry a greater

risk and a higher yield than rated securities. Although unrated bonds are not

necessarily of lower quality, the market for them may not be as broad as that

for rated bonds since many investors rely solely on the major rating agencies

for credit appraisal.



HIGH YIELD SECURITIES



The Fund invests in municipal securities rated Ba or lower by Moody's or

rated BB or lower by S&P (commonly known as "junk bonds"). There is no

minimal acceptable rating for a security to be purchased or held in the

Fund's portfolio, and the Fund may, from time to time, purchase or hold

securities rated in the lowest rating category or securities in default.



   



Lower rated securities will usually offer higher yields than higher rated

securities. However, there is more risk associated with these investments.

This is because of reduced creditworthiness and increased risk of default.

Regarding lower rated debt securities: (i) an economic downturn may have a

more significant effect on the yield, price and potential for default as

compared to debt securities of higher quality; (ii) the secondary market for

such securities may at times be less liquid or respond more adversely to

negative publicity or investor perceptions, making it more difficult to value

or dispose of the securities; (iii) the likelihood that these securities will

help the Fund achieve its investment objective is more dependent on the

adviser's own credit analysis; and (iv) lower rated debt securities may be

less sensitive to interest rate changes.



    



The Fund may, from time to time, own zero coupon bonds. A zero coupon bond

makes no periodic interest payments and the entire obligation becomes due

only upon maturity. The prices of zero coupon bonds are generally more

sensitive to fluctuations in interest rates than are conventional bonds.

Although these securities pay no interest to holders prior to maturity,

interest on these securities is reported as income to the Fund and

distributed to shareholders.



   



REDUCING RISKS OF LOWER RATED SECURITIES



    



The Fund's investment adviser believes that the risks of investing in lower

rated securities can be reduced. The professional portfolio management

techniques used by the Fund to attempt to reduce these risks include:



CREDIT RESEARCH



When purchasing bonds, rated or unrated, the Fund's investment adviser

performs its own credit analysis in addition to using recognized rating

agencies. This credit analysis considers the economic feasibility of revenue

bond project financing and general purpose borrowings, the financial

condition of the issuer or guarantor with respect to liquidity, cash flow and

ability to meet anticipated debt service requirements, and political

developments that may affect credit quality.



DIVERSIFICATION



The Fund invests in securities of many different issuers to reduce portfolio

risks.



ECONOMIC ANALYSIS



The Fund's adviser also considers trends in the overall economy, in

geographic areas, in various industries, and in the financial markets.



INVESTMENT LIMITATIONS



The Fund will not:



* borrow money directly or through reverse repurchase agreements (arrangements

in which the Fund sells a portfolio instrument for a percentage of its cash

value with an arrangement to buy it back on a set date) or pledge securities

except, under certain circumstances, the Fund may, exclusive of custodian

intra-day cash advances and the collateralization of such advances, 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; or



   



* invest more than 10% of its net assets in securities subject to restrictions

on resale under the Securities Act of 1933, except for certain restricted

securities which meet the criteria for liquidity as established by the

Directors.



    



The above investment limitations cannot be changed without shareholder

approval. The following limitation, however, may be changed by the Directors

without shareholder approval. Shareholders will be notified before any

material change in this limitation becomes effective.



The Fund 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).



NET ASSET VALUE



The Fund's net asset value ("NAV") per Share fluctuates and is based on the

market value of all securities and other assets of the Fund. The NAV for each

class of Shares may differ 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.



All purchases, redemptions and exchanges are processed at the NAV next

determined after the request in proper form is received by the Fund. The NAV

is determined as of the close of trading on the New York Stock Exchange

(normally 4:00 p.m., Eastern time) every day the New York Stock Exchange is

open.

# The contingent deferred sales charge is assessed on Shares redeemed within

one year of their purchase date.



PURCHASING SHARES



Shares of the Fund are sold on days on which the New York Stock Exchange is

open. Shares of the Fund may be purchased as described below, either through

a financial intermediary (such as a bank or broker/dealer) or by sending a

wire or check directly to the Fund. Financial intermediaries may impose

different minimum investment requirements on their customers. An account

must be established with a financial intermediary or by completing, signing,

and returning the new account form available from the Fund before Shares can

be purchased. Shareholders in certain other funds advised and distributed by

affiliates of Federated Investors, Inc. ("Federated Funds") may exchange

their Shares for Shares of the corresponding class of the Fund. The Fund

reserves the right to reject any purchase or exchange request.



In connection with any sale, Federated Securities Corp. may, from time to

time, offer certain items of nominal value to any shareholder or investor.



PURCHASING SHARES THROUGH A FINANCIAL INTERMEDIARY



Orders placed through a financial intermediary are considered received when

the Fund is notified of the purchase order or when payment is converted into

federal funds. Purchase orders through a broker/dealer must be received by

the broker before 4:00 p.m. (Eastern time) and must be transmitted by the

broker to the Fund before 5:00 p.m. (Eastern time) in order for Shares to be

purchased at that day's price. Purchase orders through other financial

intermediaries must be received by the financial intermediary and

transmitted to the Fund before 4:00 p.m. (Eastern time) in order for Shares

to be purchased at that day's price. It is the financial intermediary's

responsibility to transmit orders promptly. Financial intermediaries may

charge fees for their services.



The financial intermediary which maintains investor accounts in Class B

Shares or Class C Shares with the Fund must do so on a fully disclosed basis

unless it accounts for share ownership periods used in calculating the

contingent deferred sales charge (see "Contingent Deferred Sales Charge").

In addition, advance payments made to financial intermediaries may be subject

to reclaim by the distributor for accounts transferred to financial

intermediaries which do not maintain investor accounts on a fully disclosed

basis and do not account for share ownership periods.



PURCHASING SHARES BY WIRE



   



Shares may be purchased by Federal Reserve wire by calling the Fund. All

information needed will be taken over the telephone, and the order is

considered received when State Street Bank receives payment by wire. Federal

funds should be wired as follows: Federated Shareholder Services Company, c/

o State Street Bank and Trust Company, Boston, MA 02266-8600; Attention:

EDGEWIRE; For Credit to: (Fund Name) (Fund Class); (Fund Number-this number

can be found on the account statement or by contacting the Fund); Account

Number; Trade Date and Order Number; Group Number or Dealer Number; Nominee

or Institution Name; and ABA Number 011000028. Shares cannot be purchased by

wire on holidays when wire transfers are restricted.



    



PURCHASING SHARES BY CHECK



Shares may be purchased by mailing a check made payable to the name of the

Fund (designate class of Shares and account number) to: Federated Shareholder

Services Company, P.O. Box 8600, Boston, MA 02266-8600. Orders by mail are

considered received when payment by check is converted into federal funds

(normally the business day after the check is received).



SYSTEMATIC INVESTMENT PROGRAM



Under this program, funds in a minimum amount of $50 may be automatically

withdrawn periodically from the shareholder's checking account at an

Automated Clearing House ("ACH") member and invested in the Fund.

Shareholders should contact their financial intermediary or the Fund to

participate in this program.



CLASS A SHARES



Class A Shares are sold at NAV, plus a sales charge. However:



NO SALES CHARGE IS IMPOSED FOR CLASS A SHARES PURCHASED:



* through financial intermediaries that do not receive sales charge dealer

concessions;



* by Federated Life Members; or



* through "wrap accounts" or similar programs under which clients pay a fee for

services.



IN ADDITION, THE SALES CHARGE CAN BE REDUCED OR ELIMINATED BY:



* purchasing Class A Shares in quantity;



* combining concurrent purchases of Class A Shares



* by you, your spouse, and your children under age 21, or;



* of two or more Federated Funds (other than money market funds);



* accumulating purchases (in calculating the sales charge on an additional

purchase of Class A Shares, you may count the current value of previous

Class A Share purchases still invested in the Fund);



* signing a letter of intent to purchase a specific dollar amount of Class A

Shares within 13 months; or



* using the reinvestment privilege within 120 days of redeeming Class A Shares

of an equal or lesser amount.



Consult a financial intermediary or Federated Securities Corp. for details on

these programs. In order to eliminate the sales charge or receive sales

charge reductions, Federated Securities Corp. must be notified by the

shareholder in writing or by a financial intermediary at the time of

purchase.



DEALER CONCESSION



   



For sales of Class A Shares, the distributor will normally offer to pay a

dealer up to 90% of the applicable sales charge. Any portion of the sales

charge which is not paid to a dealer will be retained by the distributor.

However, the distributor may offer to pay dealers up to 100% of the sales

charge retained by it. Such payments may take the form of cash or promotional

incentives, such as reimbursement of certain expenses of qualified employees

to attend informational meetings about the Fund or other special events at

recreational-type facilities, or items of material value. In some instances,

these incentives will be made available only to dealers whose employees have

sold or may sell a significant amount of Class A Shares. Financial

intermediaries purchasing Class A Shares for their customers in amounts of

$1 million or more are eligible to receive an advance commission from the

distributor based on the following breakpoints:



    



                            ADVANCE

                        COMMISSION AS

                         A PERCENTAGE

                           OF PUBLIC

TRANSACTION AMOUNT      OFFERING PRICE

First $1 - $5 million       0.75%

Next $5 - $20 million       0.50%

Over $20 million            0.25%



For accounts with assets over $1 million, the dealer commission resets

annually to the first breakpoint on the anniversary of the first purchase.



Class A Share purchases under this program may be made by Letter of Intent or

by combining concurrent purchases. The above commission will be paid only on

those purchases that were not previously subject to a front-end sales charge

and dealer commission. Certain retirement accounts may not be eligible for

this program. Financial intermediaries must notify the Fund once an account

reaches $1 million in order to qualify for advance commissions.



A contingent deferred sales charge of 0.75% of the redemption amount applies

to Class A Shares redeemed up to 24 months after purchase if a financial

intermediary received an advance commission on the transaction. Federated

Securities Corp. may pay fees to banks out of the sales charge in exchange

for sales and/or administrative services performed on behalf of the bank's

customers in connection with the establishment of customer accounts and

purchases of Class A Shares.



CLASS B SHARES



Class B Shares are sold at NAV. Under certain circumstances, a contingent

deferred sales charge will be assessed at the time of a redemption. Orders

for $250,000 or more of Class B Shares will automatically be invested in

Class A Shares.



CONVERSION OF CLASS B SHARES



Class B Shares will automatically convert into Class A Shares after eight

full years from the purchase date. Such conversion will be on the basis of

the relative NAVs per Share, without the imposition of any charges. Class B

Shares acquired by exchange from Class B Shares of another Federated Fund

will convert into Class A Shares based on the time of the initial purchase.



CLASS C SHARES



Class C Shares are sold at NAV. A contingent deferred sales charge of 1.00%

will be charged on assets redeemed within the first full 12 months following

purchase.



REDEEMING AND EXCHANGING SHARES



   



Shares of the Fund may be redeemed for cash or exchanged for Shares of the

same class of other Federated Funds on days on which the Fund computes its

NAV. Shares are redeemed at NAV less any applicable contingent deferred sales

charge. Exchanges are made at NAV. Shareholders who desire to automatically

exchange Shares, of a like class, in a pre-determined amount on a monthly,

quarterly, or annual basis, may take advantage of a systematic exchange

privilege. Information on this privilege is available from the Fund or your

financial intermediary. Depending upon the circumstances, a capital gain or

loss may be realized when Shares are redeemed or exchanged.



    



REDEEMING OR EXCHANGING SHARES THROUGH A FINANCIAL INTERMEDIARY



Shares of the Fund may be redeemed or exchanged by contacting your financial

intermediary before 4:00 p.m. (Eastern time). In order for these transactions

to be processed at that day's NAV, financial intermediaries (other than

broker/dealers) must transmit the request to the Fund before 4:00 p.m.

(Eastern time), while broker/dealers must transmit the request to the Fund

before 5:00 p.m. (Eastern time). The financial intermediary is responsible

for promptly submitting transaction requests and providing proper written

instructions. Customary fees and commissions may be charged by the financial

intermediary for this service. Appropriate authorization forms for these

transactions must be on file with the Fund.



REDEEMING OR EXCHANGING SHARES BY TELEPHONE



   



Shares acquired directly from the Fund may be redeemed in any amount, or

exchanged, by calling 1-800-341-7400. Appropriate authorization forms for

these transactions must be on file with the Fund. Shares held in certificate

form must first be returned to the Fund as described in the instructions

under "Redeeming or Exchanging Shares by Mail." Redemption proceeds will

either be mailed in the form of a check to the shareholder's address of

record or wire-transferred to the shareholder's account at a domestic

commercial bank that is a member of the Federal Reserve System. The minimum

amount for a wire transfer is $1,000. Proceeds from redeemed Shares purchased

by check or through an ACH member will not be wired until that method of

payment has cleared.



    



Telephone instructions will be recorded. If reasonable procedures are not

followed by the Fund, 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 this occurs, "Redeeming or Exchanging Shares by Mail" should be

considered. The telephone transaction privilege may be modified or

terminated at any time. Shareholders would be promptly notified.



REDEEMING OR EXCHANGING SHARES BY MAIL



Shares may be redeemed in any amount, or exchanged, by mailing a written

request to: Federated Shareholder Services Company, Fund Name, Share Class,

P.O. Box 8600, Boston, MA 02266-8600. If share certificates have been issued,

they must accompany the written request. It is recommended that certificates

be sent unendorsed by registered or certified mail.



All written requests should state: Fund Name and the Share Class name; the

account name as registered with the Fund; the account number; and the number

of Shares to be redeemed or the dollar amount of the transaction. An exchange

request should also state the name of the Fund into which the exchange is to

be made. All owners of the account must sign the request exactly as the

Shares are registered. A check for redemption proceeds is normally mailed

within one business day, but in no event more than seven days, after receipt

of a proper written redemption request. Dividends are paid up to and

including the day that a redemption or exchange request is processed.



REQUIREMENTS FOR REDEMPTION



Shareholders requesting a redemption of any amount to be sent to an address

other than that on record with the Fund, or a redemption payable other than

to the shareholder of record, must have their signatures guaranteed by a

commercial or savings bank, trust company or savings association whose

deposits are insured by an organization which is administered by the Federal

Deposit Insurance Corporation; a member firm of a domestic stock exchange; or

any other "eligible guarantor institution," as defined in the Securities

Exchange Act of 1934. The Fund does not accept signatures guaranteed by a

notary public.



REQUIREMENTS FOR EXCHANGE



Shareholders must exchange Shares having an NAV equal to the minimum

investment requirements of the fund into which the exchange is being made.

Contact your financial intermediary directly or the Fund for free information

on and prospectuses for the Federated Funds into which your Shares may be

exchanged. Before the exchange, the shareholder must receive a prospectus of

the fund for which the exchange is being made.



Upon receipt of proper instructions and required supporting documents,

Shares submitted for exchange are redeemed and proceeds invested in the same

class of shares of the other fund. Signature guarantees will be required to

exchange between fund accounts not having identical shareholder

registrations. The exchange privilege may be modified or terminated at any

time. Shareholders will be notified of the modification or termination of the

exchange privilege.



SYSTEMATIC WITHDRAWAL PROGRAM



Under this program, Shares are redeemed to provide for periodic withdrawal

payments in an amount directed by the shareholder of not less than $100. To

be eligible to participate in this program, a shareholder must have an

account value of at least $10,000. A shareholder may apply for participation

in this program through his financial intermediary or by calling the Fund.



   



Because participation in this program may reduce, and eventually deplete the

shareholder's investment in the Fund, payments under this program should not

be considered as yield or income. It is not advisable for shareholders to

continue to purchase Class A Shares subject to a sales charge while

participating in this program. A contingent deferred sales charge may be

imposed on Class B and Class C Shares.



SYSTEMATIC WITHDRAWAL PROGRAM ON CLASS B SHARES



A contingent deferred sales charge will not be charged on systematic

withdrawal program redemptions of Class B Shares if:



    



* shares redeemed are 12% or less of the account value in a single year;



* the account is at least one year old;



* all dividends and capital gains distributions are reinvested; and



   



* the account has at least a $10,000 balance when the Systematic Withdrawal

Program is established (multiple Class B Share accounts cannot be

aggregated to meet this minimum balance).



A contingent deferred sales charge will be charged on redemption amounts that

exceed the 12% annual limit. In measuring the redemption percentage, the

account is valued when the Systematic Withdrawal Program is established and

then annually at calendar year-end. Redemptions can be made only at a rate of

1% monthly, 3% quarterly, or 6% semi-annually.



    



CONTINGENT DEFERRED SALES CHARGE



The contingent deferred sales charge will be deducted from the redemption

proceeds otherwise payable to the shareholder and will be retained by the

distributor. Redemptions will be processed in a manner intended to maximize

the amount of redemption which will not be subject to a contingent deferred

sales charge. The contingent deferred sales charge will not be imposed with

respect to Shares acquired through the reinvestment of dividends or

distributions of long-term capital gains. In determining the applicability

of the contingent deferred sales charge, the required holding period for your

new Shares received through an exchange will include the period for which

your original Shares were held.



ELIMINATING THE CONTINGENT DEFERRED SALES CHARGE



Upon written notification to Federated Securities Corp. or the transfer

agent, no contingent deferred sales charge will be imposed on redemptions:



* following the death or disability, as defined in Section 72(m)(7) of the

Internal Revenue Code of 1986, of the last surviving shareholder and any

designated beneficiaries;



* representing minimum required distributions from an Individual Retirement

Account or other retirement plan to a shareholder who has attained the age of

70 1/2;



* which are involuntary redemptions of shareholder accounts that do not comply

with the minimum balance requirements;



* which are qualifying redemptions of Class B Shares under a Systematic

Withdrawal Program;



* which are reinvested in the Fund under the reinvestment privilege;



* of Shares held by Directors, employees and sales representatives of the Fund,

the distributor, or affiliates of the Fund or distributor, employees of any

financial intermediary that sells Shares of the Fund pursuant to a sales

agreement with the distributor, and their immediate family members to the

extent that no payments were advanced for purchases made by these persons;

and



* of Shares originally purchased through a bank trust department, an investment

adviser registered under the Investment Advisers Act of 1940 or retirement

plans where the third party administrator has entered into certain

arrangements with Federated Securities Corp. or its affiliates, or any other

financial intermediary, to the extent that no payments were advanced for

purchases made through such entities.



For more information regarding the elimination of the contingent deferred

sales charge through a Systematic Withdrawal Program, or any of the above

provisions, contact your financial intermediary or the Fund. The Fund

reserves the right to discontinue or modify these provisions. Shareholders

will be notified of such action.



ACCOUNT AND SHARE INFORMATION



CONFIRMATIONS AND ACCOUNT STATEMENTS



Shareholders will receive detailed confirmations of transactions (except for

systematic program transactions). In addition, shareholders will receive

periodic statements reporting all account activity, including dividends

paid. The Fund will not issue share certificates.



DIVIDENDS AND DISTRIBUTIONS



Dividends are declared and paid monthly to all shareholders invested in the

Fund on the record date. Net long-term capital gains realized by the Fund, if

any, will be distributed at least once every twelve months. Dividends and

distributions are automatically reinvested in additional Shares of the Fund

on payment dates at the ex-dividend date without a sales charge, unless

shareholders request cash payments on the new account form or by contacting

the transfer agent.



ACCOUNTS WITH LOW BALANCES



Due to the high cost of maintaining accounts with low balances, the Fund may

close an account by redeeming all Shares and paying the proceeds to the

shareholder if the account balance falls below the applicable minimum

investment amount. Accounts where the balance falls below the minimum due to

NAV changes will not be closed in this manner. Before an account is closed,

the shareholder will be notified and allowed 30 days to purchase additional

Shares to meet the minimum.



FUND INFORMATION



MANAGEMENT OF THE FUND



DIRECTORS



The Fund is managed by the Board of Directors. The Directors are responsible

for managing the Fund's business affairs and for exercising all the Fund's

powers except those reserved for the shareholders. An Executive Committee of

the Directors handles the Director's responsibilities between meetings of the

Directors.



INVESTMENT ADVISER



Investment decisions for the Fund are made by Federated Advisers, the Fund's

investment adviser (the "Adviser"), subject to direction by the Directors.

The Adviser continually conducts investment research and supervision for the

Fund and is responsible for the purchase or sale of portfolio instruments,

for which it receives an annual fee from the Fund.



ADVISORY FEES



The Adviser receives an annual investment advisory fee equal to 0.60% of the

Fund's average daily net assets. The Adviser may voluntarily choose to waive

a portion of its fee or reimburse the fund for certain operating expenses.

The Adviser can terminate this voluntary waiver of its advisory fee at any

time at its sole discretion.



ADVISER'S BACKGROUND



Federated Advisers, 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 Advisers 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. The Federated Funds are presently at work in and through approximately

4,000 financial institutions nationwide.



Mary Jo Ochson has been the Fund's portfolio manager since May 1996.

Ms. Ochson joined Federated Investors, Inc. or its predecessor in 1982 and

has been a Senior Vice President of the Fund's investment adviser since

January 1996. From 1988 through 1995, Ms. Ochson served as a Vice President

of the Fund's investment adviser. Ms. Ochson is a Chartered Financial Analyst

and received her M.B.A. in Finance from the University of Pittsburgh.



J. Scott Albrecht has been the Fund's portfolio manager since May 1996.

Mr. Albrecht joined Federated Investors, Inc. or its predecessor in 1989 and

has been a Vice President of the Fund's investment adviser since 1994. From

1992 to 1994, Mr. Albrecht served as an Assistant Vice President of the

Fund's investment adviser. Mr. Albrecht is a Chartered Financial Analyst and

received his M.S. in Public Management from Carnegie Mellon University.



Both the Corporation and the Adviser have adopted strict codes of ethics

governing the conduct of all employees who manage the Fund and its portfolio

securities. These codes recognize that such persons owe a fiduciary duty to

the Fund'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 Fund; 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 Directors, and could result in severe penalties.



DISTRIBUTION OF SHARES



   



Federated Securities Corp. is the principal distributor for Shares of the

Fund. 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 Investment Company Act

Rule 12b-1 (the "Distribution Plan"), Class A Shares, Class B Shares, and

Class C Shares will pay a fee to the distributor in an amount computed at an

annual rate of 0.25%, 0.75%, and 0.75%, respectively, of the average daily

net assets of each class of Shares to finance any activity which is

principally intended to result in the sale of Shares subject to the

Distribution Plan. For Class C 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. With respect to Class B Shares, because distribution fees to be

paid by the Fund to the distributor may not exceed an annual rate of 0.75%

of each class of Shares' average daily net assets, it will take the

distributor a number of years to recoup the expenses it has incurred for its

sales services and distribution-related support services pursuant to the

Plan. The Fund is not currently making payments for Class A Shares under the

Distribution Plan, nor does it anticipate doing so in the immediate future.



    



The Distribution Plan is a compensation type Plan. As such, the Fund makes no

payments to the distributor, except as described above. Therefore, the Fund

does not pay for unreimbursed expenses of the distributor, including amounts

expended by the distributor in excess of amounts received by it from the

Fund, 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 made by Shares under the Plan.



   



In addition, the Fund has entered into a Shareholder Services Agreement with

Federated Shareholder Services, a subsidiary of Federated Investors, Inc.,

under which the Fund may make payments up to 0.25% of the average daily net

asset value of Class A Shares, Class B Shares, and Class C Shares to obtain

certain personal services for shareholders and for the maintenance of

shareholder accounts. 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

such fees will be paid will be determined from time to time by the Fund and

Federated Shareholder Services.



SUPPLEMENTAL PAYMENTS TO FINANCIAL INSTITUTIONS



In addition to payments made pursuant to the Distribution Plan and

Shareholder Services Agreement, the distributor and Federated Shareholder

Services may pay a supplemental fee from their own assets to financial

institutions as financial assistance for providing substantial sales

services, distribution-related support services, or shareholder services.

The support may include sponsoring sales, educational and training seminars

at recreational-type facilities for their employees, providing sales

literature, and engineering computer software programs that emphasize the

attributes of the Fund. 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 and Federated Shareholder

Services may be reimbursed by the Fund's Adviser or its affiliates.



    



ADMINISTRATION OF THE FUND



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 Fund. Federated

Services Company provides these at an annual rate which relates to the

average aggregate daily net assets of all of the 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.



SHAREHOLDER INFORMATION



Each Share of the Fund gives the shareholder one vote in Director elections

and other matters submitted to shareholders for vote. All Shares of each

portfolio or class in the Fund 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.



Directors may be removed by the Directors or shareholders at a special

meeting. A special meeting of shareholders shall be called by the Directors

upon the written request of shareholders owning at least 10% of the Fund's

outstanding Shares of all series entitled to vote.



   



As of November 5, 1998, the following shareholder of record owned 25% or more

of the outstanding Shares of the Fund: Merrill Lynch Pierce, Fenner & Smith

(as record owner holding Class F Shares for its clients), Jacksonville, FL,

owned approximately 7,368,354 Class F Shares (25.97%) and, therefore, may,

for certain purposes, be deemed to control the Fund and be able to affect the

outcome of certain matters presented for a vote of shareholders.



    



TAX INFORMATION



FEDERAL INCOME TAX



The Fund will pay no federal income tax because it expects to meet

requirements of the Internal Revenue Code 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 Fund that represent net interest on

tax-exempt municipal bonds. However, under the Tax Reform Act of 1986,

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, 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.



   



The Tax Reform Act of 1986 treats interest on certain "private activity"

bonds issued after August 7, 1986, 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 Fund may purchase all types of municipal bonds, including

private activity bonds. Thus, should it purchase any such bonds, a portion of

the Fund's dividends may be treated as a tax preference item.



    



In addition, in the case of a corporate shareholder, dividends of the Fund

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 alternate 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 Fund dividend, and alternative minimum

taxable income does not include the portion of the Fund'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 Fund 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 Fund 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 Fund. 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 Fund advertises its total return, yield, and tax-

equivalent yield for each class of Shares including Class F Shares as

described under "Other Classes of Shares."



Total return represents the change, over a specific period of time, in the

value of an investment in each class of Shares 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 each class of Shares is calculated by dividing the net

investment income per share (as defined by the SEC) earned by each class of

Shares over a thirty-day period by the maximum offering price per share of

each class on the last day of the period. This number is then annualized

using semi-annual compounding. The tax-equivalent yield of each class of

Shares is calculated similarly to the yield, but is adjusted to reflect the

taxable yield that each class 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 each class of Shares

and, therefore, may not correlate to the dividends or other distributions

paid to shareholders. The performance information reflects the effect of the

maximum sales charge and other similar non-recurring charges, such as the

contingent deferred sales charge, which, if excluded, would increase the

total return, yield, and tax-equivalent yield.



    



Total return, yield, and tax-equivalent yield will be calculated separately

for Class A Shares, Class B Shares, Class C Shares, and Class F Shares.



From time to time, advertisements for Class A Shares, Class B Shares, and

Class C Shares may refer to ratings, rankings, and other information in

certain financial publications and/or compare the performance of Class A

Shares, Class B Shares, and Class C Shares to certain indices.



OTHER CLASSES OF SHARES



The Fund also offers another class of shares called Class F Shares. Class F

Shares are sold primarily to customers of financial institutions subject to

a front-end sales charge, a contingent deferred sales charge and a minimum

initial investment of $1,500.



Shares and Class F Shares are subject to certain of the same expenses.

Expense differences, however, between Shares and Class F Shares may affect

the performance of each class.



To obtain more information and a prospectus for Class F Shares, investors may

call 1-800-341-7400 or contact their financial institution.



APPENDIX



MUNICIPAL BOND RATING DEFINITIONS

STANDARD AND POOR'S



AAA-Debt rated "AAA" has the highest rating assigned by Standard & Poor's

("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.



BB-Debt rated "BB" has less near-term vulnerability to default than other

speculative issues. However, it faces major ongoing uncertainties or

exposure to adverse business, financial, or economic conditions which could

lead to inadequate capacity to meet timely interest and principal payments.

The "BB" rating category is also used for debt subordinated to senior debt

that is assigned an actual or implied "BBB" rating.



   



B-Debt rated "B" has a greater vulnerability to default but currently has the

capacity to meet interest payments and principal repayments. Adverse

business, financial, or economic conditions will likely impair capacity or

willingness to pay interest and repay principal. The "B" rating category is

also used for debt subordinated to senior debt that is assigned an actual or

implied "BB" or "BB-" rating.



CCC-Debt rated "CCC" has a currently identifiable vulnerability to default,

and is dependent upon favorable business, financial, and economic conditions

to meet timely payment of interest and repayment of principal. In the event

of adverse business, financial, or economic conditions, it is not likely to

have the capacity to pay interest and repay principal. The "CCC" rating

category is also used for debt subordinated to senior debt that is assigned

an actual or implied "B" or "B-" rating.



CC-The rating "CC" typically is applied to debt subordinated to senior debt

that is assigned an actual or implied "CCC" debt rating.



C-The rating "C" typically is applied to debt subordinated to senior debt

which is assigned an actual or implied "CCC-" debt rating. The "C" rating may

be used to cover a situation where a bankruptcy petition has been filed, but

debt service payments are continued.



D-Debt rated "D" is in payment default. The "D" rating category is used when

debt service payments are not made on the date due even if the applicable

grace period has not expired, unless S&P believes that such payments will be

made during such grace period. The "D" rating also will be used upon the

filing of a bankruptcy petition or the taking of a similar action if debt

service payments are jeopardized.



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 SERVICE, INC.



Aaa-Bonds which are rated "Aaa" are judged to be of the best quality. They

carry the smallest degree of investment risk and are generally referred to as

"gilt 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.



Ba-Bonds which are rated "Ba" are judged to have speculative elements; their

future cannot be considered as well-assured. Often the protection of interest

and principal payments may be very moderate, and thereby not well safeguarded

during both good and bad times over the future. Uncertainty of position

characterizes bonds in this class.



   



B-Bonds which are rated "B" generally lack characteristics of the desirable

investment. Assurance of interest and principal payments or of maintenance of

other terms of the contract over any long period of time may be small.



Caa-Bonds which are rated "Caa" are of poor standing. Such issues may be in

default or there may be present elements of danger with respect to principal

or interest.



Ca-Bonds which are rated "Ca" represent obligations which are speculative in

a high degree. Such issues are often in default or have other marked

shortcomings.



C-Bonds which are rated "C" are the lowest rated class of bonds, and issues

so rated can be regarded as having extremely poor prospects of ever attaining

any real investment standing.



1, 2, OR 3-The ratings from "Aa" to "Caa" may be modified by the addition of

the numbers 1, 2, or 3, to show relative standing in each rating

classification. The modifier 1 indicates that the issue ranks in the higher

end of its 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

rating category.

GENERAL INFORMATION ABOUT THE FUND

   

The Fund was incorporated under the laws of the State of Maryland on

November 26, 1986. It is qualified to do business as a foreign corporation in

Pennsylvania. On March 31, 1996, the Fund changed its name from Fortress

Municipal Income Fund, Inc. to Federated Municipal Opportunities Fund, Inc.



Shares of the Fund are offered in four classes, known as Class A Shares, Class

B Shares, Class C Shares, and Class F Shares (individually and collectively

referred to as "Shares" as the context may require). This Statement of

Additional Information relates to all four of the above-mentioned classes of

Shares.

    

INVESTMENT OBJECTIVE AND POLICIES

The Fund's investment objective is to provide a high level of current income

which is generally exempt from federal regular income tax. The objective

cannot be changed without approval of shareholders.



ACCEPTABLE INVESTMENTS



CHARACTERISTICS



The municipal bonds in which the Fund invests have the characteristics set

forth in the prospectus.



If a bond loses its rating after the Fund has purchased it, the Fund is not

required to drop the bond from the portfolio, but may consider doing so. If

ratings made by Moody's Investors Service, Inc. ("Moody's") or Standard &

Poor's ("S&P") change because of changes in those organizations or in their

rating systems, the Fund will try to use comparable ratings as standards in

accordance with the investment policies described in the Fund's prospectus.



WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS



These transactions are made to secure what is considered to be an

advantageous price or yield for the Fund. No fees or other expenses, other

than normal transaction costs, are incurred. However, liquid assets of the

Fund sufficient to make payment for the securities to be purchased are

segregated on the Fund's records at the trade date. These assets are marked

to market daily and are maintained until the transaction has been settled.

The Fund does not intend to engage in when-issued and delayed delivery

transactions to an extent that would cause the segregation of more than 20%

of the total value of its assets.



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 Fund 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 Fund's anticipated holding period. The Fund 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 Fund does not pay or receive

money upon the purchase or sale of a futures contract. Rather, the Fund is

required to deposit an amount of "initial margin" in municipal securities,

cash or cash equivalents 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 Fund 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 Fund upon

termination of the futures contract, assuming all contractual obligations

have been satisfied.


A futures contract held by the Fund is valued daily at the official

settlement price of the exchange on which it is traded. Each day the Fund

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 Fund

but is instead settlement between the Fund and the broker of the amount one

would owe the other if the futures contract expired. In computing its daily

net asset value, the Fund will mark-to-market its open futures positions.



TEMPORARY INVESTMENTS



The Fund may also invest in temporary investments from time to time for

defensive purposes. The Fund does not presently intend to invest in temporary

investments other than repurchase agreements.



The Fund might invest in temporary investments:



* as a reaction to market conditions;



* while waiting to invest proceeds of sales of shares or portfolio securities,

although generally proceeds from sales of shares will be invested in

municipal bonds as quickly as possible; or



* in anticipation of redemption requests.



The Fund will not purchase temporary investments (other than securities of

the U.S. government, its agencies or instrumentalities) if, as a result of

the purchase, 25% or more of the value of its total assets would be invested

in any one industry. However, the Fund may, for temporary defensive purposes,

invest 25% or more of the value of its assets in cash or cash items,

U.S. Treasury bills or securities issued or guaranteed by the

U.S. government, its agencies or instrumentalities, or instruments secured

by these money market instruments, such as repurchase agreements.



REPURCHASE AGREEMENTS



Repurchase agreements are arrangements in which banks, broker/dealers and

other recognized financial institutions sell U.S. government securities or

certificates of deposit to the Fund and agree at the time of sale to

repurchase them at a mutually agreed upon time and price within one year from

the date of acquisition. The Fund or its custodian will take possession of

the securities subject to repurchase agreements, and these securities will be

marked-to-market daily. To the extent that the original seller does not

repurchase the securities from the Fund, the Fund could receive less than the

repurchase price on any sale of such securities. In the event that such a

defaulting seller filed for bankruptcy or became insolvent, disposition of

such securities by the Fund might be delayed pending court action. The Fund

believes that under the regular procedures normally in effect for custody of

the Fund's portfolio securities subject to repurchase agreements, a court of

competent jurisdiction would rule in favor of the Fund and allow retention or

disposition of such securities. The Fund may only enter into repurchase

agreements with banks and other recognized financial institutions such as

broker/dealers which are found by the Fund's adviser to be creditworthy

pursuant to guidelines established by the Board of Directors. From time to

time, such as when suitable municipal bonds are not available, the Fund may

retain a portion of its assets in cash. Any portion of the Fund's assets

maintained in cash will reduce the amount of assets in municipal bonds and

thereby reduce the Fund's yield.



REVERSE REPURCHASE AGREEMENTS



The Fund may also enter into reverse repurchase agreements. This transaction

is similar to borrowing cash. In a reverse repurchase agreement, the Fund

transfers possession of a portfolio instrument to another person, such as a

financial institution, broker, or dealer, in return for a percentage of the

instrument's market value in cash, and agrees that on a stipulated date in

the future the Fund will repurchase the portfolio instrument by remitting

the original consideration plus interest at an agreed upon rate. The use of

reverse repurchase agreements may enable the Fund to avoid selling portfolio

instruments at a time when a sale may be deemed to be disadvantageous, but

the ability to enter into reverse repurchase agreements does not ensure that

the Fund will be able to avoid selling portfolio instruments at a

disadvantageous time.



When effecting reverse repurchase agreements, liquid assets of the Fund, in a

dollar amount sufficient to make payment for the obligations to be purchased,

are segregated on the Fund's records at the trade date. These assets are

marked to market daily and are maintained until the transaction is settled.



PORTFOLIO TURNOVER



   

The Fund 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 Fund's investment objective. For the fiscal years ended

August 31, 1998, and August 31, 1997, the portfolio turnover rates were 41%,

and 20%, respectively.

    

INVESTMENT LIMITATIONS

BUYING ON MARGIN



The Fund will not purchase any securities on margin, but may obtain such

short-term credits as are necessary for clearance of transactions. The

deposit or payment by the Fund of initial or variation margin in connection

with financial futures contracts or related options transactions is not

considered the purchase of a security on margin.



ISSUING SENIOR SECURITIES AND BORROWING MONEY



The Fund will not issue senior securities except that the Fund may borrow

money and engage in reverse repurchase agreements in amounts up to one-third

of the value of its total assets, including the amounts borrowed.



The Fund will not borrow money or engage in reverse repurchase agreements for

investment leverage, but rather as a temporary, extraordinary, or emergency

measure or to facilitate management of the portfolio by enabling the Fund to

meet redemption requests when the liquidation of portfolio securities is

deemed to be inconvenient or disadvantageous. The Fund will not purchase any

securities while borrowings are outstanding. During the period any reverse

repurchase agreements are outstanding, but only to the extent necessary to

assure completion of the reverse repurchase agreements, the Fund will

restrict the purchase of portfolio instruments to money market instruments

maturing on or before the expiration date of the reverse repurchase

agreements.



PLEDGING ASSETS



The Fund will not mortgage, pledge, or hypothecate any assets except to

secure permitted borrowings. In those cases, it may pledge assets having a

market value not exceeding the lesser of the dollar amounts borrowed or 10%

of the value of total assets at the time of the borrowing. Neither the

deposit of underlying securities and other assets in escrow in connection

with the writing of put or call options on municipal bonds nor margin

deposits for the purchase and sale of financial futures contracts and related

options are deemed to be a pledge.



The preceding limitations regarding buying on margin, borrowing money, and

pledging assets do not apply to intra-day cash advances made by the Fund's

custodian, or the grant of a security interest in securities by the Fund to

its custodian to collateralize such intra-day cash advances, in order to

enable the Fund to settle securities purchases or to redeem Shares of the

Fund.



INVESTING IN REAL ESTATE



The Fund will not buy or sell real estate, although it may invest in

securities of companies whose business involves the purchase or sale of real

estate or in securities which are secured by real estate or interests in real

estate.



INVESTING IN COMMODITIES



The Fund will not purchase or sell commodities, except that the Fund may

purchase and sell financial futures contracts and related options.



UNDERWRITING



The Fund 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 restricted securities which the Fund may purchase pursuant

to its investment objective, policies, and limitations.



LENDING CASH OR SECURITIES



The Fund will not lend any of its assets except portfolio securities up to

one-third of the value of its total assets. This shall not prevent the

purchase or holding of municipal bonds, repurchase agreements, or other

transactions which are permitted by the Fund's investment objective and

policies.



SELLING SHORT



The Fund will not sell securities short.



RESTRICTED SECURITIES



The Fund will not invest more than 10% of its net assets in securities

subject to restrictions on resale under the Securities Act of 1933, except

for certain restricted securities which meet the criteria for liquidity as

established by the Directors.



INVESTING IN SECURITIES OF OTHER INVESTMENT COMPANIES



The Fund will not purchase securities of other investment companies except

as part of a merger, consolidation, or other acquisition.



The above investment limitations cannot be changed without shareholder

approval. The following limitations, however, may be changed by the Directors

without shareholder approval. Shareholders will be notified before any

material change in these limitations becomes effective.



DIVERSIFICATION OF INVESTMENTS



The Fund will not invest more than 5% of its total assets in the securities

of any one issuer (except cash and cash instruments, securities issued or

guaranteed by the U.S. government, its agencies, or instrumentalities or

instruments secured by money market instruments such as repurchase

agreements).



Under this limitation, each governmental subdivision, including states and

the District of Columbia, territories, possessions of the United States or

their political subdivisions, agencies, authorities, instrumentalities, or

similar entities, will 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. Industrial

development bonds backed only by the assets and revenues of a non-

governmental user are considered to be issued solely by that user.



Private activity bonds backed only by the assets and revenues of a non-

governmental user are considered to be issued solely by that user. If, in the

case of a private activity bond or government-issued security, a governmental

or other entity guarantees the security, such guarantee would be considered a

separate security issued by the guarantor as well as the other issuer,

subject to limited exclusions allowed by the Investment Company Act of 1940.



CRITERIA FOR LIQUIDITY OF RESTRICTED SECURITIES



The ability of the Directors to determine the liquidity of certain restricted

securities is permitted under a Securities and Exchange Commission ("SEC")

Staff position set forth in the adopting release for Rule 144A under the

Securities Act of 1933 (the "Rule"). The Rule is a non-exclusive safe-harbor

for certain secondary market transactions involving securities subject to

restrictions on resale under federal securities laws. The secondary market

transactions involving securities subject to restrictions on resale under

federal securities laws. The Rule provides an exemption from registration for

resales of otherwise restricted securities to qualified institutional

buyers. The Rule was expected to further enhance the liquidity of the

secondary market for securities eligible for resale under the Rule. The Fund

believes that the Staff of the SEC has left the question of determining the

liquidity of all restricted securities to the Directors. The Directors may

consider the following criteria in determining the liquidity of certain

restricted securities:



* the frequency of trades and quotes for the security;



* the number of dealers willing to purchase or sell the security and the number

of other potential buyers;



* dealer undertakings to make a market in the security; and



* the nature of the security and the nature of the marketplace trades.



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 a violation of such restriction.



During the past fiscal year, the Fund did not (1) purchase or sell options on

securities, as permitted by the investment limitations, without first

notifying shareholders; (2) purchase "liquidity puts" or "standby

commitments" as described in the prospectus, engage in reverse repurchase

agreements, or borrow money in excess of 5% of the value of its total assets;

or (3) lend portfolio securities. The Fund does not expect to engage in any

of the above activities during the coming fiscal year.



For purposes of its policies and limitations, the Fund considers certificates

of deposit and demand and time deposits issued by a U.S. branch of a domestic

bank or savings and loan having capital, surplus, and undivided profits in

excess of $100,000,000 at the time of investment to be "cash items."

 *Information is furnished for the fiscal year ended August 31, 1998.



 #The aggregate compensation is provided for the Corporation which is

comprised of one portfolio.



 +The information is provided for the last calendar year.



DIRECTOR LIABILITY



The Articles of Incorporation provide that the Directors 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 FUND



The Fund's investment adviser is Federated Advisers (the

"Adviser"). It is a subsidiary of Federated Investors, Inc. All of the voting

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 Fund or any shareholder for any losses

that may be sustained in the purchase, holding, or sale of any security or

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 Fund.



ADVISORY FEES



   

For its advisory services, Federated Advisers receives an annual investment

advisory fee as described in the prospectus. During the fiscal years ended

August 31, 1998, 1997, and 1996, the Fund's Adviser earned $2,736,122,

$2,610,540, and $2,475,132, respectively.

    

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 Directors. The Adviser may

select brokers and dealers who offer brokerage and research services. These

services may be furnished directly to the Fund 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 Fund 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. For the fiscal years ended

August 31, 1998, 1997, and 1996, the Fund paid no brokerage commissions on

brokerage transactions.



Although investment decisions for the Fund are made independently from those

of the other accounts managed by the Adviser, investments of the type the

Fund may make may also be made by those other accounts. When the Fund 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 Fund or the size of the position obtained

or disposed of by the Fund. In other cases, however, it is believed that

coordination and the ability to participate in volume transactions will be to

the benefit of the Fund.



OTHER SERVICES

   

FUND ADMINISTRATION



Federated Services Company, a subsidiary of Federated

Investors, Inc. provides administrative personnel and services to the Fund

for a fee as described in the prospectus. From March 1, 1994, to March 1,

1996, Federated Administrative Services served as the Fund's Administrator.

Prior to March 1, 1994, Federated Administrative Services, Inc. served as the

Fund's Administrator. Both former Administrators are subsidiaries of

Federated Investors, Inc. 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 August 31, 1998, 1997, and 1996,

the Administrators earned $343,950, $328,575, and $311,976.

    



CUSTODIAN AND PORTFOLIO ACCOUNTANT



State Street Bank and Trust Company, Boston, MA, is custodian for the

securities and cash of the Fund. Federated Services Company, Pittsburgh, PA,

provides certain accounting and recordkeeping services with respect to the

Fund's portfolio investments. The fee paid for this service is based upon the

level of the Fund'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 the size, type

and number of accounts and transactions made by shareholders.



INDEPENDENT AUDITORS



The independent auditors for the Fund are Deloitte & Touche LLP, Pittsburgh,

Pennsylvania.



PURCHASING SHARES

Except under certain circumstances described in the respective prospectuses,

Shares are sold at their net asset value (plus a sales charge, if applicable)

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 the Fund" and "Purchasing Shares."



QUANTITY DISCOUNTS AND ACCUMULATED PURCHASES



As described in the prospectuses, larger purchases of the same Share class

reduce or eliminate the sales charge paid. For example, the Fund will combine

all Class A Share purchases made on the same day by the investor, the

investor's spouse, and the investor's children under age 21 when it

calculates the sales charge. This combined purchase option is available

within Class F Shares as well. In addition, the sales charge, if applicable,

is reduced for purchases made at one time by a trustee or fiduciary for a

single trust estate or a single fiduciary account.



If an additional purchase into the same Share class is made, the Fund will

consider the previous purchases still invested in the Fund. For example, if a

shareholder already owns Class A Shares having a current value at the public

offering price of $90,000 and he purchases $10,000 more at the current public

offering price, the sales charge on the additional purchase according to the

schedule now in effect would be 3.75%, not 4.50%.



In addition, the Fund will also combine purchases for the purpose of reducing

the contingent deferred sales charge imposed on Class F Share redemptions.

For example, if a shareholder already owns Class F Shares having current

value at the public offering price of $1 million and purchases an additional

$1 million at the current public offering price, the applicable contingent

deferred sales charge would be reduced to 0.50% of those additional Class F

Shares.



To receive the sales charge reduction, Federated Securities Corp. must be

notified by the shareholder in writing or by his financial intermediary at

the time the purchase is made that Class A Shares or Class F Shares are

already owned or that purchases are being combined. The Fund will reduce or

eliminate the sales charge after it confirms the purchases.



CONCURRENT PURCHASES



Shareholders have the privilege of combining concurrent purchases of the same

Share class of two or more funds in the Federated Complex in calculating the

applicable sales charge.



To receive a sales charge reduction or elimination, Federated Securities

Corp. must be notified by the shareholder in writing or by his financial

intermediary at the time the concurrent purchases are made. The Fund will

reduce or eliminate the sales charge after it confirms the purchases.



LETTER OF INTENT



A shareholder can sign a letter of intent committing to purchase a certain

amount of the same Share class within a 13-month period in order to combine

such purchases in calculating the applicable sales charge. The Fund's

custodian will hold Shares in escrow equal to the maximum applicable sales

charge. If the shareholder completes the commitment, the escrowed Shares will

be released to their account. If the commitment is not completed within 13

months, the custodian will redeem an appropriate number of escrowed Shares to

pay for the applicable sales charge.



The letter of intent for Class F Shares also includes a provision for

reductions in the contingent deferred sales charge and holding period

depending on the amount actually purchased within the 13-month period.



While this letter of intent will not obligate the shareholder to purchase

Class A Shares or Class F Shares, each purchase during the period will be at

the sales charge applicable to the total amount intended to be purchased. At

the time a letter of intent is established, current balances in accounts in

any Class A Shares or Class F Shares of any Federated Funds, excluding money

market accounts, will be aggregated to provide a purchase credit towards

fulfillment of the letter of intent. The letter may be dated as of a prior

date to include any purchase made within the past 90 days. Prior trade prices

will not be adjusted.



REINVESTMENT PRIVILEGE



The reinvestment privilege is available for all Shares of the Fund within the

same Share class.



Class A and Class F shareholders who redeem from the Fund

may reinvest the redemption proceeds back into the same Share class at the

next determined net asset value without any sales charge. The original Shares

must have been subject to a sales charge and the reinvestment must be within

120 days.



Similarly, Class C and Class F shareholders who redeem may reinvest their

redemption proceeds in the same Share class within 120 days. Class B Shares

also may be reinvested within 120 days of redemption, although such

reinvestment will be made into Class A Shares. Shareholders would not be

entitled to a reimbursement of the contingent deferred sales charge if paid

at the time of redemption on any Share class. However, reinvested Shares

would not be subject to a contingent deferred sales charge, if otherwise

applicable, upon later redemption.



In addition, if Shares were reinvested through a financial intermediary, the

financial intermediary would not be entitled to an advanced payment from

Federated Securities Corp. on the reinvested Shares, if otherwise

applicable. Federated Securities Corp. must be notified by the shareholder in

writing or by his financial intermediary of the reinvestment in order to

eliminate a sales charge or a contingent deferred sales charge. If the

shareholder redeems Shares in the Fund, there may be tax consequences.



CONVERSION OF CLASS B SHARES



Class B Shares will automatically convert into Class A Shares on or around

the 15th of the month eight full years from the purchase date and will no

longer be subject to a fee under the distribution plan. For purposes of

conversion to Class A Shares, Shares purchased through the reinvestment of

dividends and distributions paid on Class B Shares will be considered to be

held in a separate sub-account. Each time any Class B Shares in the

shareholder's account (other than those in the sub-account) convert to Class

A Shares, an equal pro rata portion of the Class B Shares in the sub-account

will also convert to Class A Shares. The conversion of Class B Shares to

Class A Shares is subject to the continuing availability of a ruling from

the Internal Revenue Service or an opinion of counsel that such conversions

will not constitute taxable events for federal tax purposes. There can be no

assurance that such ruling or opinion will be available, and the conversion

of Class B Shares to Class A Shares will not occur if such a ruling or

opinion is not available. In such event, Class B Shares would continue to be

subject to higher expenses than Class A Shares for an indefinite period.



DISTRIBUTION PLAN AND SHAREHOLDER SERVICES



   

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.

    



By adopting the Distribution Plan, the Directors expect that the Fund 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 Fund in pursuing its investment objectives. By

identifying potential investors whose needs are served by the Fund'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 period ending August 31, 1998, the Fund paid distribution fees

on behalf of Class B and Class C Shares in the amounts of $220,744 and

$25,747, respectively. In addition, for this period, the Fund paid

shareholder services fees on behalf of Class A Shares, Class B Shares, Class

C Shares, and Class F Shares in the amounts of $252,181, $73,581, $8,582, and

$805,707, respectively.

    



CONVERSION TO FEDERAL FUNDS



It is the Fund's policy to be as fully invested as possible so that maximum

interest may be earned. To this end, all payments from shareholders must be

in federal funds or be converted into federal funds before shareholders begin

to earn dividends. Federated Shareholders Services acts as the shareholder's

agent in depositing checks and converting them to federal funds.



PURCHASES BY SALES REPRESENTATIVES, FUND DIRECTORS, AND EMPLOYEES



The following individuals and their immediate family members may buy Class A

Shares and Class F Shares at net asset value without a sales charge:



* Directors, employees, and sales representatives of the Fund, Federated

Advisers, and Federated Securities Corp. and its affiliates;



* Federated Life Members (Class A Shares only);



* any associated person of an investment dealer who has a sales agreement with

Federated Securities Corp.; and



* trusts, pensions, or profit-sharing plans for these individuals.



These sales are made with the purchaser's written assurance that the purchase

is for investment purposes and that the securities will not be resold except

through redemption by the Fund.



DETERMINING NET ASSET VALUE

The Fund's net asset value per Share fluctuates and is based on the market

value of all securities and other assets of the Fund. The net asset value for

each class of Shares may differ due to the variance in daily net income

realized by each class.



Net asset value is not determined on (i) days on which there are not

sufficient changes in the value of the Fund'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, President's Day, Good Friday, Memorial Day, Independence Day,

Labor Day, Thanksgiving Day, and Christmas Day.



VALUING MUNICIPAL BONDS



The Directors use an independent pricing service to value municipal bonds.

The independent pricing service takes into consideration yield, stability,

risk, quality, coupon rate, maturity, type of issuer, 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 Directors have decided that the fair value of debt securities authorized

to be purchased by the Fund 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 Fund's portfolio instruments are valued at their fair value as

determined in good faith by the Directors.



REDEEMING SHARES

The Fund redeems Shares at the next computed net asset value after the Fund

receives the redemption request. Shareholder redemptions may be subject to a

contingent deferred sales charge. Redemption procedures are explained in the

respective prospectuses under "Redeeming and Exchanging Shares." Although

the transfer agent 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



   

The Fund is obligated to redeem Shares solely in cash up to $250,000 or 1% of

the Fund's net asset value, whichever is less, for any one shareholder within

a 90-day period. Any redemption beyond this amount will also be in cash

unless the Directors determine that further payments should be in kind. In

such cases, the Fund will pay all or a portion of the remainder of the

redemption in portfolio instruments valued in the same way as the Fund

determines net asset value. The portfolio instruments will be selected in a

manner that the Directors deem fair and equitable. Redemption in kind is not

as liquid as a cash redemption. If redemption is made in kind, shareholders

who sell these securities could receive less than the redemption value and

could incur certain transaction costs.

    



CONTINGENT DEFERRED SALES CHARGE



   

In computing the amount of the applicable contingent deferred sales charge,

redemptions are deemed to have occurred in the following order: (1) Shares

acquired through the reinvestment of dividends and long-term capital gains;

(2) Shares held for more than six full years from the date of purchase with

respect to Class B Shares and one full year from the date of purchase with

respect to Class C Shares; (3) Shares held for fewer than six years with

respect to Class B Shares and for less than one full year from the date of

purchase with respect to Class C Shares on a first-in, first-out basis.

    



ELIMINATION OF THE CONTINGENT DEFERRED SALES CHARGE--CLASS B SHARES



   

To qualify for elimination of the contingent deferred sales charge through a

Systematic Withdrawal Program, the redemptions of Class B Shares must be from

an account that is at least 12 months old, has all Fund distributions

reinvested in Fund Shares, and has an account value of at least $10,000 when

the Systematic Withdrawal Program is established. Qualifying redemptions may

not exceed 1% monthly of the account value as periodically determined by the

Fund. The amounts that a shareholder may withdraw under a Systematic

Withdrawal Program that qualify for elimination of the contingent deferred

sales charge may not exceed 12% annually with reference initially to the

value of the Class B Shares upon establishment of the Systematic Withdrawal

Program and then as calculated at the annual valuation date. Redemptions on a

qualifying Systematic Withdrawal Program can be made at a rate of 1% monthly,

3% quarterly, or 6% semi-annually with reference to the applicable account

valuation amount. Amounts that exceed the 12% annual limit for redemption, as

described, may be subject to the contingent deferred sales charge. To the

extent that a shareholder exchanges Shares for Class B Shares of other

Federated Funds, the time for which the exchanged-for Shares are to be held

will be added to the time for which exchanged-from Shares were held for

purposes of satisfying the 12-month holding requirement. However, for

purposes of meeting the $10,000 minimum account value requirement, Class B

Share accounts will be not be aggregated. Any Shares purchased prior to the

termination of this program would have the contingent deferred sales charge

eliminated as provided in the Fund's prospectus at the time of the purchase

of the Shares.

    

TAX STATUS

THE FUND'S TAX STATUS



The Fund will pay no federal income tax because it expects to meet the

requirements of Subchapter M of the Internal Revenue Code applicable to

regulated investment companies and to receive the special tax treatment

afforded to such companies. To qualify for this treatment, the Fund must,

among other requirements:



* derive at least 90% of its gross income from dividends, interest, and gains

from the sale of securities;



* invest in securities within certain statutory limits; and



* distribute to its shareholders at least 90% of its net income earned during

the year.



SHAREHOLDERS' TAX STATUS



No portion of any income dividend paid by the Fund is eligible for the

dividends received deduction available to corporations.



CAPITAL GAINS



Capital gains or losses may be realized on the sale of portfolio securities

and as a result of discounts from par value on securities held to maturity.

Sales would generally be made because of:



* the availability of higher relative yields;



* differentials in market values;



* new investment opportunities;



* changes in creditworthiness of an issuer; or



* an attempt to preserve gains or limit losses.



Distribution of long-term capital gains are taxed as such, whether they are

taken in cash or reinvested and regardless of the length of time the

shareholder has owned the Shares. Any loss by a shareholder on Shares held

for less than six months and sold after a capital gains distribution will be

treated as a long-term capital loss to the extent of the capital gains

distribution.



TOTAL RETURN

The Fund's average annual total returns based on offering price for the

following periods ended August 31, 1998 were:

   

              DATE OF INITIAL                                      SINCE
SHARE CLASS  PUBLIC INVESTMENT  ONE-YEAR  FIVE-YEARS  TEN-YEARS  INCEPTION
Class A          8/5/96           8.91%      --          --        8.17%
Class B          8/5/96           8.08%      --          --        7.34%
Class C          8/5/96           8.11%      --          --        7.36%
Class F          4/10/87          8.91%     5.34%       7.70%      7.46%
    

The average annual total return for all classes of Shares of the Fund 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 offering price 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,

less any applicable sales charge, adjusted over the period by any additional

Shares, assuming a quarterly reinvestment of all dividends and

distributions. Any applicable contingent deferred sales charge is deducted

from the ending value of the investments based on the lesser of the original

purchase price or the offering price of Shares redeemed.



YIELD

The Fund's yields for the thirty-day period ended August 31, 1998, were:

   

SHARE CLASS   YIELD
Class A       4.33%
Class B       3.79%
Class C       3.79%
Class F       4.49%
    



The yield for all classes of Shares of the Fund is determined by dividing the

net investment income per Share (as defined by the SEC) earned by any class

of Shares over a thirty-day period by the maximum offering price per Share of

any class of Shares 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 any class of

Shares because of certain adjustments required by the SEC and, therefore, may

not correlate to the dividends or other distributions paid to shareholders.



To the extent that financial institutions and broker/dealers charge fees in

connection with services provided in conjunction with an investment in any

class of Shares, the performance will be reduced for those shareholders

paying those fees.



TAX-EQUIVALENT YIELD

The Fund's tax-equivalent yields for the thirty-day period ended August 31,

1998, were:

   

SHARE CLASS   YIELD
Class A       6.01%
Class B       5.26%
Class C       5.26%
Class F      6.24%
    



The tax-equivalent yield of the Fund is calculated similarly to the yield,

but is adjusted to reflect the taxable yield that the Fund would have had to

earn to equal its actual yield, assuming a 28% tax and assuming that income is

100% tax-exempt.



TAX-EQUIVALENCY TABLE



The Fund may also use a tax-equivalency table in advertising and sales

literature. The interest earned by the municipal bonds in the Fund'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-exempt" investment is an attractive choice for investors,

particularly in times of narrow spreads between tax-free and taxable yields

PERFORMANCE COMPARISONS

The Fund's performance depends upon such variables as:



* portfolio quality;



* average portfolio maturity;



* type of instruments in which the portfolio is invested;



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



* changes in Fund expenses; and



* various other factors.



The Fund's 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 Fund'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 Fund uses in

advertising may include:

FURTHUR INFORMATION ABOUT THE FUND'S PERFORMANCE IS CONTAINED IN THE FUND'S
ANNUAL REPORT, DATED AUGUST 31, 1998, WHICH CAN BE OBTAINED FREE OF CHARGE.

    



GENERAL INFORMATION



   

The Fund was incorporated under the laws of the State of Maryland on November

26, 1986. Shares of the Fund are offered in four classes of shares known as

Class A Shares, Class B Shares, Class C Shares, and Class F Shares which

represent interests in a single portfolio of securities. The Fund is designed

for individuals as a convenient means of accumulating an interest in a

professionally managed, diversified portfolio of high income municipal bonds.

This prospectus relates to Class F Shares ("Shares") of the Fund.

    



The Fund's current net asset value and offering price may be found in the

mutual funds section of local newspapers under "Federated" and the

appropriate class designation listing.

YEAR 2000 STATEMENT



Like other mutual funds and business organizations worldwide, the Fund'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 Fund 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 Fund's operations.



INVESTMENT INFORMATION



INVESTMENT OBJECTIVE



The investment objective of the Fund is to provide a high level of current

income which is generally exempt from the federal regular income tax (federal

regular income tax does not include the federal alternative minimum tax). The

investment objective cannot be changed without approval of shareholders.

While there is no assurance that the Fund will achieve its investment

objective, it endeavors to do so by following the investment policies

described in this prospectus.



   

The Fund pursues its investment objective by investing primarily in a

diversified portfolio of municipal bonds. As a matter of fundamental

investment policy, the Fund invests its assets so that at least 80% of its

annual interest income is exempt from federal regular income tax. As a matter

of non-fundamental investment policy, under normal circumstances, the Fund

will invest primarily in lower quality municipal bonds. These bonds will

usually offer higher yields than higher rated bonds but involve greater

investment risk at the time of issue. (See "Investment Risks.")

    



INVESTMENT POLICIES



Unless otherwise designated, the investment policies described below may be

changed by the Directors without shareholder approval. Shareholders will be

notified before any material change in these policies becomes effective.



ACCEPTABLE INVESTMENTS



   

Municipal bonds are debt obligations issued by or on behalf of states,

territories and possessions of the United States, including the District of

Columbia, and their political subdivisions, agencies and instrumentalities,

the interest from which is exempt from the federal regular income tax. It is

likely, however, that shareholders will be required to include interest from

a portion of the municipal bonds owned by the Fund in calculating the federal

individual alternative minimum tax or the federal alternative minimum tax for

corporations.

    



CHARACTERISTICS



The municipal bonds in which the Fund generally invests are rated Baa or

lower by Moody's Investors Service, Inc. ("Moody's") or rated BBB or lower by

Standard & Poor's ("S&P"). The Fund may buy bonds which are unrated but which

the adviser judges to be similar in quality to those rated bonds which it

purchases. (See "High Yield Securities.") A description of the ratings

categories is contained in the Appendix to this prospectus.



   

The Fund may invest any or all of its assets in higher quality tax-exempt

securities when the difference in returns between those securities and lower

quality securities is very narrow or when the adviser expects increased

volatility in interest rates. This may reduce the Fund's current income.

    



WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS



The Fund may purchase securities on a when-issued or delayed delivery basis.

These transactions are arrangements in which the Fund purchases securities

with payment and delivery scheduled for a future time. The seller's failure

to complete these transactions may cause the Fund 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 Fund may dispose of a commitment prior to settlement if the adviser deems

it appropriate to do so. In addition, the Fund 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 Fund may realize short-term profits or losses upon the sale

of such commitments.

    



INVERSE FLOATERS



The Fund may invest in securities known as "inverse floaters" which represent

interests in municipal securities. The Fund intends to purchase inverse

floaters to assist in duration management and to seek current income. 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 Fund 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 Fund may not purchase or sell futures contracts if immediately

thereafter the sum of the amount of margin deposits on the Fund's existing

futures positions would exceed 5% of the market value of the Fund's total

assets. When the Fund 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 Fund's custodian (or the broker,

if legally permitted) to collateralize the position.



RISKS



When the Fund 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 Fund's portfolio. This may cause the

futures contract to react differently than the portfolio securities to market

changes. In addition, the Fund'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 Fund 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 Fund's ability to establish and

close out futures positions depends on this secondary market.



TEMPORARY INVESTMENTS



The Fund invests its assets so that at least 80% of its annual interest

income is exempt from the federal regular income tax, except when investing

for "defensive" purposes as described below. This policy cannot be changed

without approval of shareholders. From time to time on a temporary basis, or

when the investment adviser determines that market conditions call for a

temporary defensive posture, the Fund may invest all of its assets in higher

quality tax-exempt or taxable temporary investments. These temporary

investments include: fixed or variable rate notes issued by or on behalf of

municipal or corporate issuers; obligations issued or guaranteed by the U.S.

government, its agencies or instrumentalities; other debt securities;

commercial paper; certificates of deposit of banks; and repurchase

agreements (arrangements in which the organization selling the Fund a bond or

temporary investment 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.

However, the investment adviser will limit temporary investments to those it

considers to be of good quality.



OTHER INVESTMENT TECHNIQUES



The Fund may purchase a right to sell a security held by it back to the issuer

or to another party at an agreed upon price at any time during a stated period

or on a certain date. These rights may be referred to as "liquidity puts" or

"standby commitments."



The Fund may also hedge all or a portion of its investments by entering into

futures contracts or options on them. Any gains realized on futures contracts

and options thereon are taxable. The Fund will notify shareholders before it

engages in these futures transactions.



PORTFOLIO TURNOVER



Although the Fund does not intend to invest for the purpose of seeking short-

term profits, securities in its portfolio will be sold whenever the Fund's

investment adviser believes it is appropriate to do so in light of the Fund's

investment objective, without regard to the length of time a particular

security may have been held.



MUNICIPAL BONDS



Municipal bonds are generally issued to finance public works such as

airports, bridges, highways, housing, hospitals, mass transportation

projects, schools, streets, and water and sewer works. Municipal bonds are

also issued to repay outstanding obligations, to raise funds for general

operating expenses, and to make loans to other public institutions and

facilities. Certain types of "private activity" municipal bonds are issued to

obtain funding for privately operated facilities.



There are two categories of municipal bonds: general obligation and revenue.

General obligation bonds are backed by the taxing power of the issuing

municipality. Revenue bonds are backed by the revenues of a project or

facility. Payment of principal and interest on such bonds is dependent solely

on the revenue generated by the facility financed by the bond or other

specified sources of revenue or collateral. Private activity bonds are

typically one type of "revenue" bonds.



In most cases, lower quality bonds are private activity bonds or other

revenue bonds which are not payable from general tax revenues. The Fund may

invest more than 25% of the value of its assets in private activity bonds

which may result in more than 25% of the Fund's assets being invested in one

industry. It is also possible that the Fund may from time to time invest more

than 25% of its assets in health care facilities revenue obligations, housing

agency revenue obligations or electric utility obligations. Economic,

business, political and other developments generally affecting the revenues

of issuers in such a market segment (for example, proposed legislation or

pending court decisions affecting the financing of projects and market

factors affecting the demand for their services or products) may have a

general adverse impact on all municipal bonds in the segment.



The Fund does not intend to purchase securities if, as a result of such

purchase, more than 25% of the value of its total assets would be invested in

the securities of governmental subdivisions located in any one state,

territory or possession of the United States.



INVESTMENT RISKS



The value of Shares will fluctuate. The amount of this fluctuation is

dependent upon the quality and maturity of the municipal bonds in the Fund's

portfolio as well as on market conditions. Generally speaking, the lower

quality, long-term bonds in which the Fund invests have greater fluctuation

in value than high quality, shorter-term bonds.



Municipal bond prices are interest rate sensitive, which means that their

value varies inversely with market interest rates. Thus, if market interest

rates have increased from the time a bond was purchased, the bond, if sold,

might be sold at a price less than its cost. Similarly, if market interest

rates have declined from the time a bond was purchased, the bond, if sold,

might be sold at a price greater than its cost. (In either instance, if the

bond was held to maturity, no loss or gain normally would be realized as a

result of interim market fluctuations.)



Prices of lower grade bonds also fluctuate with changes in the perceived

quality of the credit of their issuers. Consequently, Shares may not be

suitable for persons who cannot assume the somewhat greater risks of capital

depreciation associated with higher tax-exempt income yields. In addition,

lower grade bonds have speculative characteristics. Changes in economic

conditions or other circumstances are more likely to lead to weakened

capacity to make principal and interest payments than higher rated bonds.



A large portion of the Fund's portfolio may be invested in bonds whose

interest payments are from revenues of similar projects (such as housing or

hospitals) or where issuers share the same geographic location. As a result,

the Fund may be more susceptible to similar economic, political or regulatory

developments than would a portfolio of bonds with a greater geographic and

project variety. This susceptibility may result in greater fluctuations in

share price.



Many issuers of municipal bonds which have characteristics of rated bonds

choose to not have their obligations rated. Unrated bonds may carry a greater

risk and a higher yield than rated securities. Although unrated bonds are not

necessarily of lower quality, the market for them may not be as broad as that

for rated bonds since many investors rely solely on the major rating agencies

for credit appraisal.



HIGH YIELD SECURITIES



The Fund invests in municipal securities rated Ba or lower by Moody's or

rated BB or lower by S&P (commonly known as "junk bonds"). There is no

minimal acceptable rating for a security to be purchased or held in the

Fund's portfolio, and the Fund may, from time to time, purchase or hold

securities rated in the lowest rating category or securities in default.



Lower rated securities will usually offer higher yields than higher rated

securities. However, there is more risk associated with these investments.

This is because of reduced creditworthiness and increased risk of default.

Regarding lower rated debt securities: (i) an economic downturn may have a

more significant effect on the yield, price and potential for default as

compared to debt securities of higher quality; (ii) the secondary market for

such securities may at times be less liquid or respond more adversely to

negative publicity or investor perceptions, making it more difficult to value

or dispose of the securities; (iii) the likelihood that these securities will

help the Fund achieve its investment objective is more dependent on the

adviser's own credit analysis; and (iv) lower rated debt securities may be

less sensitive to interest rate changes.



The Fund may, from time to time, own zero coupon bonds. A zero coupon bond

makes no periodic interest payments and the entire obligation becomes due

only upon maturity. The prices of zero coupon bonds are generally more

sensitive to fluctuations in interest rates than are conventional bonds.

Although these securities pay no interest to holders prior to maturity,

interest on these securities is reported as income to the Fund and

distributed to shareholders.



<R

REDUCING RISKS OF LOWER RATED SECURITIES





The Fund's investment adviser believes that the risks of investing in lower

rated securities can be reduced. The professional portfolio management

techniques used by the Fund to attempt to reduce these risks include:



CREDIT RESEARCH



When purchasing bonds, rated or unrated, the Fund's investment adviser

performs its own credit analysis in addition to using recognized rating

agencies. This credit analysis considers the economic feasibility of revenue

bond project financing and general purpose borrowings, the financial

condition of the issuer or guarantor with respect to liquidity, cash flow and

ability to meet anticipated debt service requirements, and political

developments that may affect credit quality.



DIVERSIFICATION



The Fund invests in securities of many different issuers to reduce portfolio

risks.



ECONOMIC ANALYSIS



The Fund's adviser also considers trends in the overall economy, in

geographic areas, in various industries, and in the financial markets.



INVESTMENT LIMITATIONS



The Fund will not:



* borrow money directly or through reverse repurchase agreements

(arrangements in which the Fund sells a portfolio instrument for a percentage

of its cash value with an arrangement to buy it back on a set date) or pledge

securities except, under certain circumstances, the Fund may, exclusive of

custodian intra-day cash advances and the collateralization of such

advances, 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; or



* invest more than 10% of its net assets in securities subject to

restrictions on resale under the Securities Act of 1933, except for certain

restricted securities which meet the criteria for liquidity as established by

the Directors.



* The above investment limitations cannot be changed without shareholder

approval. The following limitation, however, may be changed by the Directors

without shareholder approval. Shareholders will be notified before any

material change in this limitation becomes effective.



* The Fund 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).



NET ASSET VALUE



The Fund's net asset value ("NAV") per Share fluctuates and is based on the

market value of all securities and other assets of the Fund. The NAV for each

class of Shares may differ 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.



All purchases, redemptions and exchanges are processed at the NAV next

determined after the request in proper form is received by the Fund. The NAV

is determined as of the close of trading on the New York Stock Exchange

(normally 4:00 p.m., Eastern time) every day the New York Stock Exchange is

open.

PURCHASING SHARES



Shares of the Fund are sold on days on which the New York Stock Exchange is

open. Shares of the Fund may be purchased as described below, either through

a financial intermediary (such as a bank or broker/dealer) or by sending a

wire or check directly to the Fund. Financial intermediaries may impose

different minimum investment requirements on their customers. An account

must be established with a financial intermediary or by completing, signing,

and returning the new account form available from the Fund before Shares can

be purchased. Shareholders in Class F Shares of certain other funds advised

and distributed by affiliates of Federated Investors, Inc. ("Federated

Funds") may exchange their Shares for Class F Shares of the Fund. The Fund

reserves the right to reject any purchase or exchange request.



In connection with any sale, Federated Securities Corp. may, from time to

time, offer certain items of nominal value to any shareholder or investor.



PURCHASING SHARES THROUGH A FINANCIAL INTERMEDIARY



Orders placed through a financial intermediary are considered received when

the Fund is notified of the purchase order or when payment is converted into

federal funds. Purchase orders through a broker/dealer must be received by

the broker before 4:00 p.m. (Eastern time) and must be transmitted by the

broker to the Fund before 5:00 p.m. (Eastern time) in order for Shares to be

purchased at that day's price. Purchase orders through other financial

intermediaries must be received by the financial intermediary and transmitted

to the Fund before 4:00 p.m. (Eastern time) in order for Shares to be

purchased at that day's price. It is the financial intermediary's

responsibility to transmit orders promptly. Financial intermediaries may

charge fees for their services.



The financial intermediary which maintains investor accounts in Class F Shares

with the Fund must do so on a fully disclosed basis unless it accounts for

share ownership periods used in calculating the contingent deferred sales

charge (see "Contingent Deferred Sales Charge"). In addition, advance

payments made to financial intermediaries may be subject to reclaim by the

distributor for accounts transferred to financial intermediaries which do not

maintain investor accounts on a fully disclosed basis and do not account for

share ownership periods.



PURCHASING SHARES BY WIRE



   

Shares may be purchased by Federal Reserve wire by calling the Fund. All

information needed will be taken over the telephone, and the order is

considered received when State Street Bank receives payment by wire. Federal

funds should be wired as follows: Federated Shareholder Services Company, c/

o State Street Bank and Trust Company, Boston, MA 02266-8600; Attention:

EDGEWIRE; For Credit to: (Fund Name) (Fund Class); (Fund Number-this number

can be found on the account statement or by contacting the Fund); Account

Number; Trade Date and Order Number; Group Number or Dealer Number; Nominee

or Institution Name; and ABA Number 011000028. Shares cannot be purchased by

wire on holidays when wire transfers are restricted.

    



PURCHASING SHARES BY CHECK



Shares may be purchased by mailing a check made payable to the name of the Fund

(designate class of Shares and account number) to: Federated Shareholder

Services Company, P.O. Box 8600, Boston, MA 02266-8600. Orders by mail are

considered received when payment by check is converted into federal funds

(normally the business day after the check is received).



SYSTEMATIC INVESTMENT PROGRAM



Under this program, funds in a minimum amount of $50 may be automatically

withdrawn periodically from the shareholder's checking account at an

Automated Clearing House ("ACH") member and invested in the Fund.

Shareholders should contact their financial intermediary or the Fund to

participate in this program.



ELIMINATING THE SALES CHARGE



Class F Shares are sold at NAV, plus a sales charge. However:



NO SALES CHARGE IS IMPOSED FOR CLASS F SHARES PURCHASED:



* through bank trust departments or investment advisers registered under the

Investment Advisers Act of 1940 purchasing on behalf of their clients;



* by sales representatives, Directors, and employees of the Fund, Federated

Advisers, Federated Securities Corp. or their affiliates and their immediate

family members;



* by any investment dealer who has a sales agreement with Federated Securities

Corp. and their immediate family members, or by any trusts or pension or

profit-sharing plans for these persons or retirement plans where the third

party administrator has entered into certain arrangements with Federated

Securities Corp. or its affiliates.



IN ADDITION, THE SALES CHARGE CAN BE ELIMINATED BY:



* purchasing Class F Shares in quantity;



* combining concurrent purchases of Class F Shares



   * by you, your spouse, and your children under age 21, or;



   * of two or more Federated Funds (other than money market funds);



* accumulating purchases (in calculating the sales charge on an additional

purchase of Class A Shares, you may count the current value of previous Class

A Share purchases still invested in the Fund);



* signing a letter of intent to purchase a specific dollar amount of Class F

Shares  within 13 months; or



* using the reinvestment privilege within 120 days of redeeming Class F Shares

of an equal or lesser amount.



Consult a financial intermediary or Federated Securities Corp. for details on

these programs. In order to eliminate the sales charge or receive sales

charge reductions, Federated Securities Corp. must be notified by the

shareholder in writing or by a financial intermediary at the time of

purchase.



DEALER CONCESSION



For sales of Shares,  a dealer will normally receive up to 100% of the

appicable sales charge. Any portion of the sales charge which is not paid to

a dealer will be retained by the distributor. However, the distributor may

offer to pay dealers up to 100% of the sales charge retained by it. The sales

charge for Shares sold other than through registered broker/dealers will be

retained by Federated Securities Corp.



Federated Securities Corp. may pay fees to banks out of the sales charge in

exchange for sales and/or administrative services performed on behalf of the

bank's customers in connection with the establishment of customer accounts

and purchases of Shares.



REDEEMING AND EXCHANGING SHARES



   

Shares of the Fund may be redeemed for cash or exchanged for Class F Shares

of other Federated Funds on days on which the Fund computes its NAV. Shares

are redeemed at NAV less any applicable contingent deferred sales charge.

Exchanges are made at NAV. Shareholders who desire to automatically exchange

Shares, of a like Share class, in a pre-determined amount on a monthly,

quarterly, or annual basis, may take advantage of a systematic exchange

privilege. Information on this privilege is available from the Fund or your

financial intermediary. Depending upon the circumstances, a capital gain or

loss may be realized when Shares are redeemed or exchanged.

    



REDEEMING OR EXCHANGING SHARES THROUGH A FINANCIAL INTERMEDIARY



Shares of the Fund may be redeemed or exchanged by contacting your financial

intermediary before 4:00 p.m. (Eastern time). In order for these transactions

to be processed at that day's NAV, financial intermediaries (other than

broker/dealers) must transmit the request to the Fund before 4:00 p.m.

(Eastern time), while broker/dealers must transmit the request to the Fund

before 5:00 p.m. (Eastern time). The financial intermediary is responsible for

promptly submitting transaction requests and providing proper written

instructions. Customary fees and commissions may be charged by the financial

intermediary for this service. Appropriate authorization forms for these

transactions must be on file with the Fund.



REDEEMING OR EXCHANGING SHARES BY TELEPHONE



   

Shares acquired directly from the Fund may be redeemed in any amount, or

exchanged, by calling 1-800-341-7400. Appropriate authorization forms for

these transactions must be on file with the Fund. Shares held in certificate

form must first be returned to the Fund as described in the instructions

under "Redeeming or Exchanging Shares by Mail." Redemption proceeds will

either be mailed in the form of a check to the shareholder's address of

record or wire-transferred to the shareholder's account at a domestic

commercial bank that is a member of the Federal Reserve System. The minimum

amount for a wire transfer is $1,000. Proceeds from redeemed Shares purchased

by check or through an ACH member will not be wired until that method of

payment has cleared.



    



Telephone instructions will be recorded. If reasonable procedures are not

followed by the Fund, 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 this occurs, "Redeeming or Exchanging Shares by Mail" should be

considered. The telephone transaction privilege may be modified or terminated

at any time. Shareholders would be promptly notified.



REDEEMING OR EXCHANGING SHARES BY MAIL



Shares may be redeemed in any amount, or exchanged, by mailing a written

request to: Federated Shareholder Services Company, Fund Name, Share Class,

P.O. Box 8600, Boston, MA 02266-8600. If share certificates have been

issued, they must accompany the written request. It is recommended that

certificates be sent unendorsed by registered or certified mail.



All written requests should state: Fund Name and the Share Class name; the

account name as registered with the Fund; the account number; and the number

of Shares to be redeemed or the dollar amount of the transaction. An exchange

request should also state the name of the Fund into which the exchange is to

be made. All owners of the account must sign the request exactly as the

Shares are registered. A check for redemption proceeds is normally mailed

within one business day, but in no event more than seven days, after receipt

of a proper written redemption request. Dividends are paid up to and

including the day that a redemption or exchange request is processed.



REQUIREMENTS FOR REDEMPTION



Shareholders requesting a redemption of any amount to be sent to an address

other than that on record with the Fund, or a redemption payable other than

to the shareholder of record, must have their signatures guaranteed by a

commercial or savings bank, trust company or savings association whose

deposits are insured by an organization which is administered by the Federal

Deposit Insurance Corporation; a member firm of a domestic stock exchange; or

any other "eligible guarantor institution," as defined in the Securities

Exchange Act of 1934. The Fund does not accept signatures guaranteed by a

notary public.



REQUIREMENTS FOR EXCHANGE



   

Shareholders must exchange Shares having an NAV equal to the minimum

investment requirements of the fund into which the exchange is being made.

Contact your financial intermediary directly or the Fund for free information

on, and prospectuses for, the Federated Funds into which your Shares may be

exchanged. Before the exchange, the shareholder must receive a prospectus of

the fund for which the exchange is being made.

    



Upon receipt of proper instructions and required supporting documents, Shares

submitted for exchange are redeemed and proceeds invested in the same class

of shares of the other fund. Signature guarantees will be required to

exchange between fund accounts not having identical shareholder

registrations. The exchange privilege may be modified or terminated at any

time. Shareholders will be notified of the modification or termination of the

exchange privilege.



SYSTEMATIC WITHDRAWAL PROGRAM



Under this program, Shares are redeemed to provide for periodic withdrawal

payments in an amount directed by the shareholder of not less than $100. To

be eligible to participate in this program, a shareholder must have an

account value of at least $10,000. A shareholder may apply for participation

in this  program through his financial intermediary or by calling the Fund.



Because participation in this program may reduce, and eventually deplete, the

shareholder's investment in the Fund, payments under this program should not

be considered as yield or income. It is not advisable for shareholders to

continue to purchase Class F Shares subject to a sales charge while

participating in this program. A contingent deferred sales charge will be

imposed on Shares redeemed through this program within four years of their

purchase dates.



CONTINGENT DEFERRED SALES CHARGE



The contingent deferred sales charge will be deducted from the redemption

proceeds otherwise payable to the shareholder and will be retained by the

distributor. Redemptions will be processed in a manner intended to maximize

the amount of redemption which will not be subject to a contingent deferred

sales charge. The contingent deferred sales charge will not be imposed with

respect to Shares acquired through the reinvestment of dividends or

distributions of long-term capital gains. In determining the applicability of

the contingent deferred sales charge, the required holding period for your

new Shares received through an exchange will include the period for which

your original Shares were held.



ELIMINATING THE CONTINGENT DEFERRED SALES CHARGE



Upon written notification to Federated Securities Corp. or the transfer

agent, no contingent deferred sales charge will be imposed on redemptions:



* following the death or disability, as defined in Section 72(m)(7) of the

Internal Revenue Code of 1986, of the last surviving shareholder and any

designated beneficiaries;



* representing a total or partial distribution from an Individual Retirement

Account, Keogh Plan, or a custodial account to a shareholder who has attained

the age of 70-1/2;



* representing a total or partial distribution from a qualified plan, other

than an individual Retirement Account, Keogh Plan, or a custodial account

following retirement;



* which are involuntary redemptions of shareholder accounts that do not comply

with the minimum balance requirements;



* which are reinvested in the Fund under the reinvestment privilege;



* of Shares held by Directors, employees and sales representatives of the Fund,

the distributor, or affiliates of the Fund or distributor, employees of any

financial intermediary that sells Shares of the Fund pursuant to a sales

agreement with the distributor, and their immediate family members to the

extent that no payments were advanced for purchases made by these persons;

and



* of Shares originally purchased through a bank trust department, an investment

adviser registered under the Investment Advisers Act of 1940 or retirement

plans where the third party administrator has entered into certain

arrangements with Federated Securities Corp. or its affiliates, or any other

financial intermediary, to the extent that no payments were advanced for

purchases made through such entities.



For more information regarding the contingent deferred sales charge or any of

the above provisions, contact your financial intermediary or the Fund. The

Fund reserves the right to discontinue or modify these provisions.

Shareholders will be notified of such action.



ACCOUNT AND SHARE INFORMATION



CONFIRMATIONS AND ACCOUNT STATEMENTS



Shareholders will receive detailed confirmations of transactions (except for

systematic program transactions). In addition, shareholders will receive

periodic statements reporting all account activity, including dividends paid.

The Fund will not issue share certificates.



DIVIDENDS AND DISTRIBUTIONS



Dividends are declared and paid monthly to all shareholders invested in the

Fund on the record date. Net long-term capital gains realized by the Fund, if

any, will be distributed at least once every twelve months. Dividends and

distributions are automatically reinvested in additional Shares of the Fund

on payment dates at the ex-dividend date NAV without a sales charge, unless

shareholders request cash payments on the new account form or by contacting

the transfer agent.



ACCOUNTS WITH LOW BALANCES



Due to the high cost of maintaining accounts with low balances, the Fund may

close an account by redeeming all Shares and paying the proceeds to the

shareholder if the account balance falls below the applicable minimum

investment amount. Accounts where the balance falls below the minimum due to

NAV changes will not be closed in this manner. Before an account is closed,

the shareholder will be notified and allowed 30 days to purchase additional

Shares to meet the minimum.



FUND INFORMATION



MANAGEMENT OF THE FUND



DIRECTORS



The Fund is managed by the Board of Directors. The Directors are responsible

for managing the Fund's business affairs and for exercising all the Fund's

powers except those reserved for the shareholders. An Executive Committee of

the Directors handles the Director's responsibilities between meetings of

the Directors.



INVESTMENT ADVISER



Investment decisions for the Fund are made by Federated Advisers, the Fund's

investment adviser (the "Adviser"), subject to direction by the Directors.

The Adviser continually conducts investment research and supervision for the

Fund and is responsible for the purchase or sale of portfolio instruments,

for which it receives an annual fee from the Fund.



ADVISORY FEES



The Adviser receives an annual investment advisory fee equal to 0.60% of the

Fund's average daily net assets. The Adviser may voluntarily choose to waive

a portion of its fee or reimburse the Fund for certain operating expenses.

The Adviser can terminate this voluntary waiver of its advisory fee at any

time at its sole discretion.



ADVISER'S BACKGROUND



Federated Advisers, 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 Advisers 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. The Federated Funds are

presently at work in and through approximately 4,000 financial

institutions nationwide.



Mary Jo Ochson has been the Fund's portfolio manager since May 1996. Ms.

Ochson joined Federated Investors, Inc. or its predecessor in 1982 and has

been a Senior Vice President of the Fund's investment adviser since January

1996. From 1988 through 1995, Ms. Ochson served as a Vice President of the

Fund's investment adviser. Ms. Ochson is a Chartered Financial Analyst and

received her M.B.A. in Finance from the University of Pittsburgh.



J. Scott Albrecht has been the Fund's portfolio manager since May 1996. Mr.

Albrecht joined Federated Investors, Inc. or its predecessor in 1989 and has

been a Vice President of the Fund's investment adviser since 1994. From 1992

to 1994, Mr. Albrecht served as an Assistant Vice President of the Fund's

investment adviser. Mr. Albrecht is a Chartered Financial Analyst and

received his M.S. in Public Management from Carnegie Mellon University.



Both the Fund and the Adviser have adopted strict codes of ethics governing

the conduct of all employees who manage the Fund and its portfolio

securities. These codes recognize that such persons owe a fiduciary duty to

the Fund'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 Fund; 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 Directors, and could result in severe penalties.



DISTRIBUTION OF CLASS F SHARES



   

Federated Securities Corp. is the principal distributor for shares of the

Fund. 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 Investment Company Act

Rule 12b-1 (the "Plan"), the distributor may select financial institutions

such as banks, fiduciaries, custodians for public funds, investment advisers

and brokers/dealers to provide sales services or distribution-related support

services as agents for their clients or customers. The Fund is not currently

making payments for Class F Shares under the Distribution Plan, nor does it

anticipate doing so in the immediate future.



The distributor will pay financial institutions a fee based upon Shares

subject to the Plan and owned by their clients or customers. The schedules of

such fees and the basis upon which such fees will be paid will be determined

from time to time by the Directors of the Fund provided that for any period

the total amount of these fees shall not exceed an annual rate of 0.25% of

the average net asset value of shares subject to the Plan held during the

period by clients or customers of financial institutions. The current annual

rate of such fees is 0.25%. Any fees paid by the distributor under the Plan,

will be reimbursed from the assets of the Fund.



   

In addition, the Fund has entered into a Shareholder Services Agreement with

Federated Shareholder Services, a subsidiary of Federated Investors, Inc.,

under which the Fund may make payments up to 0.25% of the average daily net

asset value of the Fund to obtain certain personal services for shareholders

and to provide the maintenance of shareholder accounts. 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 such fees will be paid will be determined from time

to time by the Fund and Federated Shareholder Services.

    



SUPPLEMENTAL PAYMENTS TO FINANCIAL INSTITUTIONS



The distributor will pay brokers and financial institutions, for distribution

and/or administrative services, an amount equal to 1% of the offering price

of the shares acquired by their clients or customers on purchases up to

$1,999,999, 0.50% of the offering price on purchases of $2,000,000 to

$4,999,999, and 0.25% of the offering price on purchases of $5,000,000 or

more. (This fee is in addition to the 1% sales charge on purchases of less

than $1 million.) Any fees paid by the distributor pursuant to these

administrative arrangements will be reimbursed by the Adviser. The

administrator may elect to receive amounts less than those stated, which

would reduce the stated contingent deferred sales charge and/or the holding

period used to calculate the fee.



   

Furthermore, in addition to payments made pursuant to the Plan and

Shareholder Services Agreement, the distributor and Federated Shareholder

Services may pay a supplemental fee from their own assets to financial

institutions as financial assistance for providing substantial sales

services, distribution-related support services, or shareholder services.

The support may include sponsoring sales, educational and training seminars

at recreational-type facilities for their employees, providing sales

literature, and engineering computer software programs that emphasize the

attributes of the Fund. 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 and Federated Shareholder Services may

be reimbursed by the Fund's Adviser or its affiliates.

    



ADMINISTRATION OF THE FUND



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 Fund. Federated

Services Company provides these at an annual rate which relates to the

average aggregate daily net assets of all of the 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.



SHAREHOLDER INFORMATION



Each Share of the Fund gives the shareholder one vote in Director elections

and other matters submitted to shareholders for vote. All Shares of each

portfolio or class in the Fund 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.



Directors may be removed by the Directors or by shareholders at a special

meeting. A special meeting of shareholders shall be called by the Directors

upon the written request of shareholders owning at least 10% of the Fund's

outstanding shares of all series entitled to vote.



   

As of November 5, 1998, the following shareholder of record owned 25% or more

of the outstanding Shares of the Fund: Merrill Lynch Pierce Fenner & Smith

(as record owner holding Class F Shares for its clients), Jacksonville,

Florida, owned approximately 7,368,354 Class F Shares (25.97%) and,

therefore, may, for certain purposes, be deemed to control the Fund and be

able to affect the outcome of certain matters presented for a vote of

shareholders.

    



TAX INFORMATION



FEDERAL INCOME TAX



The Fund will pay no federal income tax because it expects to meet

requirements of the Internal Revenue Code 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 Fund that represent net interest on

tax-exempt municipal bonds. However, under the Tax Reform Act of 1986,

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, 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.



The Tax Reform Act of 1986 treats interest on certain "private activity"

bonds issued after August 7, 1986, 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 Fund may purchase all types of municipal bonds, including

private activity bonds. Thus, should it purchase any such bonds, a portion of

the Fund's dividends may be treated as a tax preference item.



In addition, in the case of a corporate shareholder, dividends of the Fund

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 alternate 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 Fund dividend, and alternative minimum

taxable income does not include the portion of the Fund'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 Fund 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 Fund 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 Fund. 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 Fund advertises its total return, yield, and tax-

equivalent yield for Class F Shares including Class A Shares, Class B Shares,

and Class C Shares as described under "Other Classes of Shares."



Total return represents the change, over a specific period of time, in the

value of an investment in Shares 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 is calculated by dividing the net investment income per

share (as defined by the SEC) earned by the Fund 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 performance information reflects the effect of the maximum sales charge

and other similar non-recurring charges, such as the contingent deferred

sales charge, which, if excluded, would increase the total return, yield, and

tax-equivalent yield.



   

Total return, yield and tax-equivalent yield will be calculated separately

for Class A Shares, Class B Shares, Class C Shares, and Class F Shares.

    



From time to time, advertisements for the Fund may refer to ratings, rankings,

and other information in certain financial publications and/or compare the

Fund's performance to certain indices.



OTHER CLASSES OF SHARES



   

The Fund also offers other classes of shares called Class A Shares, Class B

Shares, and Class C Shares which are all sold primarily to customers of

financial institutions subject to certain differences.

    



Class A Shares are sold at net asset value subject to a front-end sales

charge, and a shareholder services fee, and are distributed pursuant to a

Rule 12b-1 Plan. Investments in Class A Shares are subject to a minimum

initial investment of $500.



Class B Shares are sold at net asset value subject to a contingent deferred

sales charge, a shareholder services fee, and are distributed pursuant to a

Rule 12b-1 Plan. Investments in Class B Shares are subject to a minimum

initial investment of $1,500.



Class C Shares are sold at net asset value subject to a contingent deferred

sales charge, a shareholder services fee, and are distributed pursuant to a

Rule 12b-1 Plan. Investments in Class C Shares are subject to a minimum

investment of $1,500.





   

Class A Shares, Class B Shares, Class C Shares, and Class F Shares are

subject to certain of the same expenses. Expense differences, however,

between Class A Shares, Class B Shares, Class C Shares, and Class F Shares

may affect the performance of each class.



To obtain more information and a combined prospectus for Class A Shares,

Class B Shares, and Class C Shares, investors may call 1-800-341-7400 or

contact their financial institution.

    



APPENDIX



MUNICIPAL BOND RATING DEFINITIONS



STANDARD & POOR'S



AAA--Debt rated "AAA" has the highest rating assigned by Standard &

Poor's("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.



BB--Debt rated "BB" has less near-term vulnerability to default than other

speculative issues. However, it faces major ongoing uncertainties or exposure

to adverse business, financial, or economic conditions which could lead to

inadequate capacity to meet timely interest and principal payments. The "BB"

rating category is also used for debt subordinated to senior debt that is

assigned an actual or implied "BBB" rating.



   



B--Debt rated "B" has a greater vulnerability to default but currently has the

capacity to meet interest payments and principal repayments. Adverse

business, financial, or economic conditions will likely impair capacity or

willingness to pay interest and repay principal. The "B" rating category is

also used for debt subordinated to senior debt that is assigned an actual or

implied "BB" or "BB-" rating.



CCC--Debt rated "CCC" has a currently identifiable vulnerability to default,

and is dependent upon favorable business, financial, and economic conditions

to meet timely payment of interest and repayment of principal. In the event

of adverse business, financial, or economic conditions, it is not likely to

have the capacity to pay interest and repay principal. The "CCC" rating

category is also used for debt subordinated to senior debt that is assigned

an actual or implied "B" or "B-" rating.



CC--The rating "CC" typically is applied to debt subordinated to senior debt

that is assigned an actual or implied "CCC" debt rating.



C--The rating "C" typically is applied to debt subordinated to senior debt

which is assigned an actual or implied "CCC-" debt rating. The "C" rating may

be used to cover a situation where a bankruptcy petition has been filed, but

debt service payments are continued.



D--Debt rated "D" is in payment default. The "D" rating category is used when

debt service payments are not made on the date due even if the applicable

grace period has not expired, unless S&P believes that such payments will be

made during such grace period. The "D" rating also will be used upon the

filing of a bankruptcy petition or the taking of a similar action if debt

service payments are jeopardized.



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.

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.



Ba--Bonds which are "Ba" are judged to have speculative elements; their future

cannot be considered as well-assured. Often the protection of interest and

principal payments may be very moderate, and thereby not well safeguarded

during both good and bad times over the future. Uncertainty of position

characterizes bonds in this class.



   



B--Bonds which are rated "B" generally lack characteristics of the desirable

investment. Assurance of interest and principal payments or of maintenance of

other terms of the contract over any long period of time may be small.



Caa--Bonds which are rated "Caa" are of poor standing. Such issues may be in

default or there may be present elements of danger with respect to principal

or interest.



Ca--Bonds which are rated "Ca" represent obligations which are speculative in

a high degree. Such issues are often in default or have other marked

shortcomings.



C--Bonds which are rated "C" are the lowest rated class of bonds, and issues

so rated can be regarded as having extremely poor prospects of ever attaining

any real investment standing.



1, 2, OR 3--The ratings from "Aa" to "Caa" may be modified by the addition of

the numbers 1, 2, or 3, to show relative standing in each rating

classification. The modifier 1 indicates that the issue ranks in the higher

end of its 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

rating category.
