Risk/Return Bar Chart and Table
The Bar Chart and Performance Table below reflect historical performance data
for Automated Government Cash Reserves (the "Former Fund") prior to its
reorganization into the Fund, which is a newly created portfolio of Money Market
Obligations Trust (the "Trust"). On the date of the reorganization, ________,
1999, the Former Fund was dissolved and its net assets (inclusive of liabilities
recorded on the Former Fund's records) were transferred to the Fund.

The graphic presentation displayed here consists of a bar chart representing the
annual total returns of the Former Fund as of the calendar year-end for each of
eight years.

The `y' axis reflects the "% Total Return" beginning with "0" and increasing in
increments of 1% up to 6%.

The `x' axis represents calculation periods from the earliest first full
calendar year end of the Former Fund's start of business through the calendar
year ended December 31, 1998. The light gray shaded chart features eight
distinct vertical bars, each shaded in charcoal, and each visually representing
by height the total return percentages for the calendar year stated directly at
its base. The calculated total return percentage for the Former Fund for each
calendar year is stated directly at the top of each respective bar, for the
calendar years 1991 through 1998. The percentages noted are: 5.60%, 3.29%,
2.71%, 3.81%, 5.45%, 4.89%, 5.04% and 4.96%.

Historically, the Former Fund has maintained a constant $1.00 net asset value
per share. The bar chart shows the variability of the Former Fund's total
returns on a calendar year-end basis.

The Former Fund's Shares were not sold subject to a sales charge (load). The
total returns displayed above are based upon the net asset value.

The Former Fund's total return from January 1, 1999 to March 31, 1999 was 1.08%.

Within the period shown in the Chart, the Former Fund's highest quarterly return
was 1.54% (quarter ended March 31, 1991). Its lowest quarterly return was 0.66%
(quarters ended March 31, 1993 and June 30, 1993).

The following table represents the Fund's Average Annual Total Returns for the
calendar periods ending December 31, 1998.


Average Annual Total Return Table
Calendar Period       Fund
1 Year                4.96%
5 Years               4.83%
Start of Performance1 4.80%

1 The Former Fund's start of performance date was February 2, 1990. The Former
Fund's 7-Day Net Yield as of December 31, 1998 was 4.54%.

Investors may call the Fund at 1-800-341-7400 to acquire the current 7-Day Net
Yield.

Past performance does not necessarily predict future performance. This
information provides you with historical performance information so that you can
analyze whether the Fund's investment risks are balanced by its potential
rewards.

2  The adviser expects to voluntarily waive a portion of the management fee. The
   adviser can terminate this anticipated voluntary waiver at any time. The
   management fee paid by the Fund (after the anticipated voluntary waiver) is
   expected to be 0.23% for the fiscal year ending April 30, 2000.

   Automated Government Cash Reserves, the Former Fund, as a portfolio of Money
   Market Obligations Trust, the Total Annual Fund Operating Expenses and Total
   Actual Annual Fund Operating Expenses (after waivers) were 0.86% and 0.59%,
   respectively.



Example
The following Example is intended to help you compare the cost of investing in
the Fund with the cost of investing in other mutual funds.
  The Example assumes that you invest $10,000 in the Fund for the time periods
indicated and then redeem all of your Shares at the end of those periods. The
Example also assumes that your investment has a 5% return each year and that the
Fund's operating expenses are before waivers as estimated in the table and
remain the same. Although your actual costs may be higher or lower, based on
these assumptions your costs would be:

         1 Year       3 Years        5 Years       10 Years

<PAGE>



WHAT ARE THE FUND'S INVESTMENT STRATEGIES?
The Fund invests only in a portfolio of U.S. Treasury and government agency
securities maturing in 397 days or less. The dollar-weighted average maturity of
the Fund's portfolio will be 90 days or less.

The adviser targets a dollar-weighted average portfolio maturity range based
upon its interest rate outlook. The adviser formulates its interest rate outlook
by analyzing a variety of factors, such as:

o current U.S. economic activity and the economic outlook ;

o current short-term interest rates;

o the Federal Reserve Board's policies regarding short-term interest rates, and

o    the  potential  effects of foreign  economic  activity  on U.S.  short-term
     interest rates.

The adviser generally shortens the portfolio's dollar-weighted average maturity
when it expects interest rates to rise and extends the maturity when it expects
interest rates to fall. The adviser selects securities used to lengthen or
shorten the portfolio's dollar-weighted average maturity by comparing the
returns currently offered by different investments to their historical and
expected returns.


WHAT ARE THE PRINCIPAL SECURITIES IN WHICH THE FUND INVESTS?
Fixed Income Securities

Fixed income securities pay interest, dividends or distributions at a specified
rate. The rate may be a fixed percentage of the principal or adjusted
periodically. In addition, the issuer of a fixed income security must repay the
principal amount of the security, normally within a specified time. The Fund
invests in the following types of fixed income securities.

     Treasury securities

     Treasury securities are direct obligations of the federal government of the
United States.

     Agency securities

     Agency securities are issued or guaranteed by a federal agency or other
     government sponsored entity acting under federal authority (a GSE). The
     United States supports some GSEs with its full faith and credit. Other GSEs
     receive support through federal subsidies, loans or other benefits. A few
     GSEs have no explicit financial support, but are regarded as having implied
     support because the federal government sponsors their activities.


WHAT ARE THE SPECIFIC RISKS OF INVESTING IN THE FUND?

Although there are many factors that may affect an investment in the Fund, the
principal risk of investing in a U.S. government money market fund is described
below.

Interest Rate Risk

Prices of fixed income securities rise and fall in response to changes in the
interest rate paid by similar securities. Generally, when interest rates rise,
prices of fixed income securities fall. However, market factors, such as demand
for particular fixed income securities, may cause the price of certain fixed
income securities to fall while the prices of other securities rise or remain
unchanged.

Interest rate changes have a greater effect on the price of fixed income
securities with longer maturities. Money market funds try to minimize this risk
by purchasing short-term securities.


WHAT DO SHARES COST?

You can purchase or redeem Shares any day the New York Stock Exchange (NYSE) is
open. The Fund attempts to stabilize the net asset value (NAV) of its Shares at
$1.00 by valuing the portfolio securities using the amortized cost method. The
Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The
Fund does not charge a front-end sales charge. NAV is determined at 12:00 noon,
1:00 p.m. (Eastern time) and as of the end of regular trading (normally 4:00
p.m. Eastern time) each day the NYSE is open.

The required minimum initial investment for Fund Shares is $25,000. There is no
required minimum subsequent investment amount.

An account may be opened with a smaller amount as long as the $25,000 minimum is
reached within 90 days. An institutional investor's minimum investment is
calculated by combining all accounts it maintains with the Fund. Accounts
established through investment professionals may be subject to a smaller minimum
investment amount. Keep in mind that investment professionals may charge you
fees for their services in connection with your Share transactions.


HOW IS THE FUND SOLD?

The Fund's Distributor markets the Shares described in this prospectus to
institutional investors, such as corporations, unions, hospitals, insurance
companies and municipalities, or individuals, directly or through investment
professionals.

The  Distributor  and its  affiliates  may pay out of their assets other amounts
(including  items of material value) to investment  professionals  for marketing
and servicing  Shares.  The Distributor is a subsidiary of Federated  Investors,
Inc. (Federated).


HOW TO PURCHASE SHARES

You may purchase Shares through an investment professional or directly from the
Fund. The Fund reserves the right to reject any request to purchase Shares.


THROUGH AN INVESTMENT PROFESSIONAL
o        Establish an account with the investment professional; and

o  Submit your purchase order to the investment professional before 2:00
   (Eastern time). You will receive that day's dividend if the investment
   professional forwards the order to the Fund and the Fund receives payment by
   2:00 (Eastern time). You will become the owner of Shares and receive
   dividends when the Fund receives your payment.

Investment professionals should send payments according to the instructions in
the sections "By Wire" or "By Check."


DIRECTLY FROM THE FUND

o    Establish  your account with the Fund by submitting a completed New Account
     Form; and

o        Send your payment to the Fund by Federal Reserve wire or check.

You will become the owner of Shares after the Fund receives your wire or your
check. If your check does not clear, your purchase will be canceled and you
could be liable for any losses or fees the Fund or its transfer agent incurs.

An institution may establish an account and place an order by calling the Fund
and will become a shareholder after the Fund receives the order.


By Wire Send your wire to:

   State Street Bank and Trust Company

requires a street address, mail it to:

   Federated Shareholder Services Company

Payment  should be made in U.S.  dollars and drawn on a U.S. bank. The Fund will
not accept  third-party  checks (checks originally payable to someone other than
you or The Federated Funds).

Orders by mail are considered received when payment by check is converted into
federal funds (normally the business day after the check is received) and Shares
begin earning dividends the next day.


BY Automatic Investments
You may establish an account with your financial institution to automatically
purchase Shares on pre-determined dates or when your bank account reaches a
certain level. Under this program, participating financial institutions are
responsible for prompt transmission of orders and may charge you for this
service. You should read this prospectus along with your financial institution's
agreement or materials describing this service.


BY AUTOMATED CLEARING HOUSE (ACH)
Once you have opened an account, you may purchase additional Shares through a
depository institution that is an ACH member. This purchase option can be
established by completing the appropriate sections of the New Account Form.


RETIREMENT INVESTMENTS
You may purchase Shares as retirement investments (such as qualified plans and
IRAs or transfer or rollover of assets). Call your investment professional or
the Fund for information on retirement investments. We suggest that you discuss
retirement investments with your tax adviser. You may be subject to an annual
IRA account fee.




<PAGE>



HOW TO REDEEM SHARES

You should redeem Shares:

o    through an  investment  professional  if you  purchased  Shares  through an
     investment professional; or

o        directly from the Fund if you purchased Shares directly from the Fund.


THROUGH AN INVESTMENT PROFESSIONAL
Submit your redemption request to your investment professional by the end of
regular trading on the NYSE (normally 4:00 p.m. Eastern time). Investment
professionals are responsible for promptly submitting redemption requests and
providing proper written redemption instructions as outlined below.


DIRECTLY FROM THE FUND

By Telephone
You may redeem Shares by calling the Fund once you have completed the
appropriate authorization form for telephone transactions.

If you call before 2:00 p.m. (Eastern time) your redemption will be wired to you
the same day. You will not receive that day's dividend.

If you call after 2:00 p.m. (Eastern time) your redemption will be wired to you
the following business day. You will receive that day's dividend.


By Mail
You may redeem Shares by mailing a written request to the Fund.

Your redemption request will be processed on the day the Fund receives your
written request in proper form. Dividends are paid up to and including the day
that a redemption request is processed.

Send requests by mail to:
   Federated Shareholder Services Company
   P.O. Box 8600
   Boston, MA 02266-8600
Send requests by private courier or overnight delivery service to:

   Federated Shareholder Services Company
   1099 Hingham Street
   Rockland, MA 02370-3317 All requests must include:

o        Fund Name and Share Class, account number and account registration;

o        amount to be redeemed; and

o        signatures of all Shareholders exactly as registered.

Call your investment professional or the Fund if you need special instructions.


Signature Guarantees Signatures must be guaranteed if:

o    your  redemption  will be sent to an  address  other  than the  address  of
     record;

o    your  redemption  will be sent to an  address  of record  that was  changed
     within the last 30 days; or

o    a redemption is payable to someone other than the shareholder(s) of record.

A signature guarantee is designed to protect your account from fraud. Obtain a
signature guarantee from a bank or trust company, savings association, credit
union or broker, dealer, or securities exchange member. A notary public cannot
provide a signature guarantee.


PAYMENT METHODS FOR REDEMPTIONS
Your redemption proceeds will be mailed by check to your address of record. The
following payment options are available if you complete the appropriate section
of the New Account Form or an Account Service Options Form. These payment
options require a signature guarantee if they were not established when the
account was opened:

o    an electronic  transfer to your account at a financial  institution that is
     an ACH member; or

o wire payment to your account at a domestic commercial bank that is a Federal
Reserve System member.


Redemption in Kind
Although the Fund intends to pay Share redemptions in cash, it reserves the
right to pay the redemption price in whole or in part by a distribution of the
Fund's portfolio securities.


LIMITATIONS ON REDEMPTION PROCEEDS
Redemption proceeds normally are wired or mailed within one business day after
receiving a request in proper form. Payment may be delayed up to seven days:

o        to allow your purchase to clear;

o        during periods of market volatility; or

o when a shareholder's trade activity or amount adversely impacts the Fund's
ability to manage its assets.

You will not accrue interest or dividends on uncashed checks from the Fund if
those checks are undeliverable and returned to the Fund.


REDEMPTIONS FROM RETIREMENT ACCOUNTS
In the absence of your specific instructions, 10% of the value of your
redemption from a retirement account in the Fund may be withheld for taxes. This
withholding only applies to certain types of retirement accounts.


CHECKWRITING
You may request checks to redeem your Fund Shares. Your account will continue to
receive the daily dividend declared on the Shares being redeemed until the check
is presented for payment.


DEBIT CARD
You may request a debit card account that allows you to redeem Shares. There is
an annual fee for this service that the Fund will automatically deduct from your
account.




ADDITIONAL CONDITIONS

Telephone Transactions
The Fund will record your telephone instructions. If the Fund does not follow
reasonable procedures, it may be liable for losses due to unauthorized or
fraudulent telephone instructions.


Share Certificates
The Fund no longer issues share certificates. If you are redeeming Shares
represented by certificates previously issued by the Fund, you must return the
certificates with your written redemption request. For your protection, send
your certificates by registered or certified mail, but do not endorse them.


ACCOUNT AND SHARE INFORMATION


Account Activity
You will receive periodic statements reporting all account activity, including
dividends and capital gains paid.


DIVIDENDS AND CAPITAL GAINS
The Fund declares any dividends daily and pays them monthly to shareholders. If
you purchase shares by wire, you begin earning dividends on the day your wire is
received. If you purchase shares by check, you begin earning dividends on the
business day after the Fund receives your check. In either case, you earn
dividends through the day your redemption request is received.

The Fund does not expect to realize any capital gains or losses. If capital
gains or losses were to occur, they could result in an increase or decrease in
dividends. The Fund pays any capital gains at least annually. Your dividends and
capital gains distributions will be automatically reinvested in additional
Shares without a sales charge, unless you elect cash payments.


ACCOUNTS WITH LOW BALANCES
Due to the high cost of maintaining accounts with low balances, non-retirement
accounts may be closed if redemptions cause the account balance to fall below
the minimum initial investment amount. Before an account is closed, you will be
notified and allowed 30 days to purchase additional Shares to meet the minimum.


TAX INFORMATION
The Fund sends an annual statement of your account activity to assist you in
completing your federal, state and local tax returns. Fund distributions of
dividends and capital gains are taxable to you whether paid in cash or
reinvested in the Fund. Dividends are taxable as ordinary income; capital gains
are taxable at different rates depending upon the length of time the Fund holds
its assets.

Fund distributions are expected to be primarily dividends. Redemptions are
taxable sales. Please consult your tax adviser regarding your federal, state,
and local tax liability.


WHO MANAGES THE FUND?

The Board of Trustees governs the Fund. The Board selects and oversees the
Adviser, Federated Investment Management Company. The Adviser manages the Fund's
assets, including buying and selling portfolio securities. The Adviser's address
is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 175 mutual
funds and separate accounts, which total approximately $111 billion in assets as
of December 31, 1998. Federated was established in 1955 and is one of the
largest mutual fund investment managers in the United States with approximately
1,900 employees. More than 4,000 investment professionals make Federated Funds
available to their customers.


Advisory Fees
The Adviser receives an annual investment advisory fee of 0.50% of the Fund's
average daily net assets. The Adviser may voluntarily waive a portion of its fee
or reimburse the Fund for certain operating expenses.


Year 2000 Readiness
The "Year 2000" problem is the potential for computer errors or failures because
certain computer systems may be unable to interpret dates after December 31,
1999 or experience other date-related problems. The Year 2000 problem may cause
systems to process information incorrectly and could disrupt businesses, such as
the Fund, that rely on computers.

While it is impossible to determine in advance all of the risks to the Fund, the
Fund could experience interruptions in basic financial and operational
functions. Fund shareholders could experience errors or disruptions in Fund
share transactions or Fund communications.

The Fund's service providers are making changes to their computer systems to fix
any Year 2000 problems. In addition, they are working to gather information from
third-party providers to determine their Year 2000 readiness.

Year 2000 problems would also increase the risks of the Fund's investments. To
assess the potential effect of the Year 2000 problem, the Adviser is reviewing
information regarding the Year 2000 readiness of issuers of securities the Fund
may purchase. The financial impact of these issues for the Fund is still being
determined. There can be no assurance that potential Year 2000 problems would
not have a material adverse effect on the Fund.

HOW IS THE FUND ORGANIZED?

The Fund is a diversified portfolio of Money Market Obligations Trust (Trust).
The Trust is an open-end, management investment company that was established
under the laws of the Commonwealth of Massachusetts on October 3, 1988. The
Trust may offer separate series of shares representing interests in separate
portfolios of securities. The Fund, which was established on December 7, 1989,
was reorganized as a portfolio of the Trust on ______________, 1999. The Fund's
investment adviser is Federated Investment Management Company.


SECURITIES IN WHICH THE FUND INVESTS

In pursuing its investment strategy, the Fund may invest in the following
securities for any purpose that is consistent with its investment objective.


SECURITIES DESCRIPTIONS AND TECHNIQUES
Fixed Income Securities
Fixed income securities pay interest, dividends or distributions at a specified
rate. The rate may be a fixed percentage of the principal or adjusted
periodically. In addition, the issuer of a fixed income security must repay the
principal amount of the security, normally within a specified time. Fixed income
securities provide more regular income than equity securities. However, the
returns on fixed income securities are limited and normally do not increase with
the issuer's earnings. This limits the potential appreciation of fixed income
securities as compared to equity securities. A security's yield measures the
annual income earned on a security as a percentage of its price. A security's
yield will increase or decrease depending upon whether it costs less (a
discount) or more (a premium) than the principal amount. If the issuer may
redeem the security before its scheduled maturity, the price and yield on a
discount or premium security may change based upon the probability of an early
redemption. Securities with higher risks generally have higher yields. The
following describes the types of fixed income securities in which the Fund
invests.
     Treasury Securities
     Treasury securities are direct obligations of the federal government of the
     United States. Treasury securities are generally regarded as having the
     lowest credit risks. Agency Securities Agency securities are issued or
     guaranteed by a federal agency or other government sponsored entity acting
     under federal authority (a GSE). The United States supports some GSEs with
     its full faith and credit. Other GSEs receive support through federal
     subsidies, loans or other benefits. A few GSEs have no explicit financial
     support, but are regarded as having implied support because the federal
     government sponsors their activities. Agency securities are generally
     regarded as having low credit risks, but not as low as treasury securities.

     Zero Coupon Securities
     Zero coupon securities do not pay interest or principal until final
     maturity unlike debt securities that provide periodic payments of interest
     (referred to as a coupon payment). Investors buy zero coupon securities at
     a price below the amount payable at maturity. The difference between the
     purchase price and the amount paid at maturity represents interest on the
     zero coupon security. Investors must wait until maturity to receive
     interest and principal, which increases the interest rate risks and credit
     risks of a zero coupon security.

     There are many forms of zero coupon securities. Some are issued at a
     discount and are referred to as zero coupon or capital appreciation bonds.
     Others are created from interest bearing bonds by separating the right to
     receive the bond's coupon payments from the right to receive the bond's
     principal due at maturity, a process known as coupon stripping. In
     addition, some securities give the issuer the option to deliver additional
     securities in place of cash interest payments, thereby increasing the
     amount payable at maturity. These are referred to as pay-in-kind or PIK
     securities.

Special Transactions
     Delayed Delivery Transactions
     Delayed delivery transactions, including when issued transactions, are
     arrangements in which the Fund buys securities for a set price, with
     payment and delivery of the securities scheduled for a future time. During
     the period between purchase and settlement, no payment is made by the Fund
     to the issuer and no interest accrues to the Fund. The Fund records the
     transaction when it agrees to buy the securities and reflects their value
     in determining the price of its shares. Settlement dates may be a month or
     more after entering into these transactions so that the market values of
     the securities bought may vary from the purchase prices. Therefore, delayed
     delivery transactions create interest rate risks for the Fund. Delayed
     delivery transactions also involve credit risks in the event of a
     counterparty default. Asset Coverage In order to secure its obligations in
     connection with special transactions, the Fund will either own the
     underlying assets, enter into an offsetting transaction or set aside
     readily marketable securities with a value that equals or exceeds the
     Fund's obligations. Unless the Fund has other readily marketable assets to
     set aside, it cannot trade assets used to secure such obligations without
     terminating a special transaction. This may cause the Fund to miss
     favorable trading opportunities or to realize losses on special
     transactions.

INVESTMENT RISKS

There are many factors which may affect an investment in the Fund. The Fund's
principal risks are described in its prospectus. Additional risk factors are
outlined below.


Credit Risk
Credit risk is the possibility that an issuer will default on a security by
failing to pay interest or principal when due. If an issuer defaults, the Fund
will lose money.

Credit risk includes the possibility that a party to a transaction involving the
Fund will fail to meet its obligations. This could cause the Fund to lose the
benefit of the transaction or prevent the Fund from selling or buying other
securities to implement its investment strategy.

INVESTMENT LIMITATIONS

Diversification

With respect to securities comprising 75% of the value of its total assets, the
Fund will not purchase securities of any one issuer (other than cash; cash
items; securities issued or guaranteed by the government of the United States or
its agencies or instrumentalities and repurchase agreements collateralized by
such U.S. government securities; and securities of other investment companies)
if, as a result, more than 5% of the value of its total assets would be invested
in securities of that issuer, or the Fund would own more than 10% of the
outstanding voting securities of that issuer.

Concentration

The Fund will not make investments that will result in the concentration of its
investments in the securities of issuers primarily engaged in the same industry.
Government securities, municipal securities and bank instruments are not deemed
to constitute an industry.

Issuing Senior Securities and Borrowing Money

The Fund may borrow money, directly or indirectly, and issue senior securities
to the maximum extent permitted under the 1940 Act.

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 pledge.



<PAGE>


Lending Cash or Securities

The Fund will not lend any of its assets, except that it may purchase or hold
U.S. government securities as permitted by its investment objective, policies
and limitations or Declaration of Trust.

Investing in Real Estate

The Fund may not purchase or sell real estate, provided that this restriction
does not prevent the Fund from investing in issuers which invest, deal, or
otherwise engage in transactions in real estate or interests therein, or
investing in securities that are secured by real estate or interests therein.
The Fund may exercise its rights under agreements relating to such securities,
including the right to enforce security interests and to hold real estate
acquired by reason of such enforcement until that real estate can be liquidated
in an orderly manner.

Underwriting Securities

The Fund may not underwrite the securities of other issuers, except that the
Fund may engage in transactions involving the acquisition, disposition or resale
of its portfolio securities, under circumstances where it may be considered to
be an underwriter under the Securities Act of 1933.

Investing in Commodities

The Fund may not purchase or sell physical commodities, provided that the Fund
may purchase securities of companies that deal in commodities.

The above limitations cannot be changed unless authorized by the "vote of a
majority of its outstanding voting securities," as defined by the Investment
Company Act. The following limitations, however, may be changed by the Board
without shareholder approval. Shareholders will be notified before any material
change in these limitations becomes effective.

Buying on Margin

The Fund will not purchase securities on margin, provided that the Fund may
obtain short-term credits necessary for the clearance of purchases and sales of
securities.

Investing in Illiquid Securities

The Fund will not purchase securities for which there is no readily available
market, or enter into repurchase agreements or purchase time deposits maturing
in more than seven days, if immediately after and as a result, the value of such
securities would exceed, in the aggregate, 10% of the Fund's net assets.

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.

For purposes of the above limitations, the Fund considers certificates of
deposit and demand and time deposits issued by a U.S. branch of a domestic bank
or savings association having capital, surplus, and undivided profits in excess
of $100,000,000 at the time of investment to be "cash items." Except with
respect to borrowing money, if a percentage limitation is adhered to at the time
of 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 limitation.

For purposes of the above policy concerning concentration, in conformity with an
SEC position, the Fund considers "bank instruments" to be limited to instruments
of domestic banks.

Regulatory Compliance

The Fund may follow non-fundamental operational policies that are more
restrictive than its fundamental investment limitations, as set forth in the
prospectus and this Statement of Additional Information, in order to comply with
applicable laws and regulations, including the provisions of and regulations
under the Investment Company Act of 1940. In particular, the Fund will comply
with the various requirements of Rule 2a-7 (the "Rule"), which regulates money
market mutual funds. The Fund will determine the effective maturity of its
investments according to the Rule. The Fund may change these operational
policies to reflect changes in the laws and regulations without the approval of
its shareholders.


DETERMINING MARKET VALUE OF SECURITIES
The Trustees have decided that the best method for determining the value of
portfolio instruments is amortized cost. Under this method, portfolio
instruments are valued at the acquisition cost as adjusted for amortization of
premium or accumulation of discount rather than at current market value.
Accordingly, neither the amount of daily income nor the net asset value is
affected by any unrealized appreciation or depreciation of the portfolio. In
periods of declining interest rates, the indicated daily yield on shares of the
Fund computed by dividing the annualized daily income on the Fund's portfolio by
the net asset value computed as above may tend to be higher than a similar
computation made by using a method of valuation based upon market prices and
estimates. In periods of rising interest rates, the opposite may be true.

The Fund's use of the amortized cost method of valuing portfolio instruments
depends on its compliance with certain conditions in the Rule. Under the Rule,
the Trustees must establish procedures reasonably designed to stabilize the net
asset value per share, as computed for purposes of distribution and redemption,
at $1.00 per share, taking into account current market conditions and the Fund's
investment objective. The procedures include monitoring the relationship between
the amortized cost value per share and the net asset value per share based upon
available indications of market value. The Trustees will decide what, if any,
steps should be taken if there is a difference of more than 0.5 of 1% between
the two values. The Trustees will take any steps they consider appropriate (such
as redemption in kind or shortening the average portfolio maturity) to minimize
any material dilution or other unfair results arising from differences between
the two methods of determining net asset value.


HOW IS THE FUND SOLD?

Under the  Distributor's  Contract  with the Fund,  the  Distributor  (Federated
Securities Corp.) offers Shares on a continuous, best-efforts basis.


SHAREHOLDER SERVICES
The Fund may pay Federated Shareholder Services Company, a subsidiary of
Federated Investors, Inc. (Federated), for providing shareholder services and
maintaining shareholder accounts. Federated Shareholder Services Company may
select others to perform these services for their customers and may pay them
fees.


SUPPLEMENTAL PAYMENTS
Investment professionals may be paid fees out of the assets of the Distributor
and/or Federated Shareholder Services Company (but not out of Fund assets). The
Distributor and/or Federated Shareholder Services Company may be reimbursed by
the Adviser or its affiliates.

Investment professionals receive such fees for providing distribution-related or
shareholder services such as sponsoring sales, providing sales literature,
conducting training seminars for employees, and engineering sales-related
computer software programs and systems. Also, investment professionals may be
paid cash or promotional incentives, such as reimbursement of certain expenses
relating to attendance at informational meetings about the Fund or other special
events at recreational-type facilities, or items of material value. These
payments will be based upon the amount of Shares the investment professional
sells or may sell and/or upon the type and nature of sales or marketing support
furnished by the investment professional.


SUBACCOUNTING SERVICES

Certain investment professionals may wish to use the transfer agent's
subaccounting system to minimize their internal recordkeeping requirements. The
transfer agent may charge a fee based on the level of subaccounting services
rendered. Investment professionals holding Shares in a fiduciary, agency,
custodial, or similar capacity may charge or pass through subaccounting fees as
part of or in addition to normal trust or agency account fees. They may also
charge fees for other services that may be related to the ownership of Shares.
This information should, therefore, be read together with any agreement between
the customer and the investment professional about the services provided, the
fees charged for those services, and any restrictions and limitations imposed.


REDEMPTION IN KIND

Although the Fund intends to pay Share redemptions in cash, it reserves the
right, as described below, to pay the redemption price in whole or in part by a
distribution of the Fund's portfolio securities.

Because the Fund has elected to be governed by Rule 18f-1 under the Investment
Company Act of 1940, the Fund is obligated to pay Share redemptions to any one
shareholder in cash only up to the lesser of $250,000 or 1% of the net assets
represented by such Share class during any 90-day period.

Any Share redemption payment greater than this amount will also be in cash
unless the Fund's Board determines that payment should be in kind. In such a
case, the Fund will pay all or a portion of the remainder of the redemption in
portfolio securities, valued in the same way as the Fund determines its NAV. The
portfolio securities will be selected in a manner that the Fund's Board deems
fair and equitable and, to the extent available, such securities will be readily
marketable.

Redemption in kind is not as liquid as a cash redemption. If redemption is made
in kind, shareholders receiving the portfolio securities and selling them before
their maturity could receive less than the redemption value of the securities
and could incur certain transaction costs.


MASSACHUSETTS PARTNERSHIP LAW

Under certain circumstances, shareholders may be held personally liable as
partners under Massachusetts law for obligations of the Trust. To protect its
shareholders, the Trust has filed legal documents with Massachusetts that
expressly disclaim the liability of its shareholders for acts or obligations of
the Trust.

In the unlikely event a shareholder is held personally liable for the Trust's
obligations, the Trust is required by the Declaration of Trust to use its
property to protect or compensate the shareholder. On request, the Trust will
defend any claim made and pay any judgment against a shareholder for any act or
obligation of the Trust. Therefore, financial loss resulting from liability as a
shareholder will occur only if the Trust itself cannot meet its obligations to
indemnify shareholders and pay judgments against them.


ACCOUNT AND SHARE INFORMATION


VOTING RIGHTS
Each share of the Fund gives the shareholder one vote in Trustee elections and
other matters submitted to shareholders for vote.

 All Shares of the Trust have equal voting rights, except that in matters
affecting only a particular Fund or class, only Shares of that Fund or class are
entitled to vote.

Trustees may be removed by the Board or by shareholders at a special meeting. A
special meeting of shareholders will be called by the Board upon the written
request of shareholders who own at least 10% of the Trust's outstanding shares
of all series entitled to vote.

As of ______________, the following shareholders owned of record, beneficially,
or both, 5% or more of outstanding Shares:


TAX INFORMATION


FEDERAL INCOME TAX
The Fund intends to meet requirements of Subchapter M of the Internal Revenue
Code applicable to regulated investment companies. If these requirements are not
met, it will not receive special tax treatment and will pay federal income tax.

The Fund will be treated as a single, separate entity for federal income tax
purposes so that income earned and capital gains and losses realized by the
Trust's other portfolios will be separate from those realized by the Fund.


WHO MANAGES AND PROVIDES SERVICES TO THE FUND?


BOARD OF TRUSTEES
The Board is responsible for managing the Trust's business affairs and for
exercising all the Trust's powers except those reserved for the shareholders.
Information about each Board member is provided below and includes each
person's: name, address, birth date, present position(s) held with the Trust,
principal occupations for the past five years and positions held prior to the
past five years, total compensation received as a Trustee from the Trust for its
most recent fiscal year, and the total compensation received from the Federated
Fund Complex for the most recent calendar year. The Trust is comprised of
fifteen Funds and The Federated Fund Complex is comprised of 56 investment
companies, whose investment advisers are affiliated with the Trust's Adviser.

As of ___________, 1999, the Fund's Board and Officers as a group owned less
than 1% of the Fund's outstanding shares.

+Mr. Donahue is the father of J. Christopher Donahue, President of the Trust.

++Messrs. Cunningham , Mansfield, and Walsh became members of the Board of
Trustees on January 1, 1999. They did not earn any fees for serving the Fund
Complex since these fees are reported as of the end of the last calendar year.
They did not receive any fees as of the fiscal year end of the Trust.


INVESTMENT ADVISER
The Adviser conducts investment research and makes investment decisions for the
Fund.

The Adviser is a wholly owned subsidiary of Federated.

The Adviser shall not be liable to the Trust or any Fund 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 Trust.


Other Related Services
Affiliates of the Adviser may, from time to time, provide certain electronic
equipment and software to institutional customers in order to facilitate the
purchase of Fund Shares offered by the Distributor.


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. 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. In selecting among firms believed to meet these
criteria, the Adviser may give consideration to those firms which have sold or
are selling Shares of the Fund and other funds distributed by the Distributor
and its affiliates. The Adviser makes decisions on portfolio transactions and
selects brokers and dealers subject to review by the Fund's Board.


Research Services
Investment decisions for the Fund are made independently from those of other
accounts managed by the Adviser. When the Fund and one or more of those accounts
invests in, or disposes of, the same security, available investments or
opportunities for sales will be allocated among the Fund and the account(s) in a
manner believed by the Adviser to be equitable. While the coordination and
ability to participate in volume transactions may benefit the Fund, it is
possible that this procedure could adversely impact the price paid or received
and/or the position obtained or disposed of by the Fund.


ADMINISTRATOR

personnel and services (including certain legal and financial reporting
services) necessary to operate the Fund. Federated Services Company provides
these at the following annual rate of the average aggregate daily net assets of

reimburse the Fund for expenses.

services with respect to the Fund's portfolio investments for a fee based on
Fund assets plus out-of-pocket expenses.

HOW DOES THE FUND MEASURE PERFORMANCE?

The Fund may advertise Share performance by using the Securities and Exchange
Commission's (SEC) standard method for calculating performance applicable to all
mutual funds. The SEC also permits this standard performance information to be
accompanied by non-standard performance information.

Unless otherwise stated, any quoted Share performance reflects the effect of
non-recurring charges, such as maximum sales charges, which, if excluded, would
increase the total return and yield. The performance of Shares depends upon such
variables as: portfolio quality; average portfolio maturity; type and value of
portfolio securities; changes in interest rates; changes or differences in the
Fund's or any class of Shares' expenses; and various other factors.

Share performance fluctuates on a daily basis largely because net earnings
fluctuate daily. Both net earnings and offering price per Share are factors in
the computation of yield and total return.

TOTAL RETURN
Total return represents the change (expressed as a percentage) in the value of
Shares over a specific period of time, and includes the investment of income and
capital gains distributions.

The average annual total return for Shares 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 NAV 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 the annual reinvestment of all
dividends and distributions.


YIELD
The yield of Shares is based upon the seven days ending on the day of the
calculation, called the "base period." This yield is calculated by: determining
the net change in the value of a hypothetical account with a balance of one
Share at the beginning of the base period, with the net change excluding capital
changes but including the value of any additional Shares purchased with
dividends earned from the original one Share and all dividends declared on the
original and any purchased Shares; dividing the net change in the account's
value by the value of the account at the beginning of the base period to
determine the base period return; and multiplying the base period return by
365/7. The effective yield is calculated by compounding the unannualized
base-period return by: adding one to the base-period return, raising the sum to
the 365/7th power; and subtracting one from the result.

To the extent investment professionals and broker/dealers charge fees in
connection with services provided in conjunction with an investment in Shares,
the Share performance is lower for shareholders paying those fees.




PERFORMANCE COMPARISONS
Advertising and sales literature may include:

o........references  to ratings,  rankings,  and financial  publications  and/or
     performance comparisons of Shares to certain indices;

o  charts, graphs and illustrations using the Fund's returns, or returns in
   general, that demonstrate investment concepts such as tax-deferred
   compounding, dollar-cost averaging and systematic investment;

o  discussions of economic, financial and political developments and their

in which it invests, to a variety of other investments, including federally
insured bank products such as bank savings accounts, certificates of deposit,
and Treasury bills.

The Fund may quote information from reliable sources regarding individual
countries and regions, world stock exchanges, and economic and demographic
statistics.

Risk/Return Bar Chart and Table
The Bar Chart and Performance Table below reflect historical performance data
for Automated Treasury Cash Reserves (the "Former Fund") prior to its
reorganization into the Fund, which is a newly created portfolio of Money Market
Obligations Trust (the "Trust"). On the date of the reorganization, ________,
1999, the Former Fund was dissolved and its net assets (inclusive of liabilities
recorded on the Former Fund's records) were transferred to the Fund.

The graphic presentation displayed here consists of a bar chart representing the
annual total returns of the Former Fund as of the calendar year-end for each of
seven years.

The `y' axis reflects the "% Total Return" beginning with "0" and increasing in
increments of 1% up to 6%.

The `x' axis represents calculation periods from the earliest first full
calendar year end of the Former Fund's start of business through the calendar
year ended December 31, 1998. The light gray shaded chart features seven
distinct vertical bars, each shaded in charcoal, and each visually representing
by height the total return percentages for the calendar year stated directly at
its base. The calculated total return percentage for the Former Fund for each
calendar year is stated directly at the top of each respective bar, for the
calendar years 1992 through 1998. The percentages noted are: 3.12%, 2.60%,
3.52%, 5.22%, 4.74%, 4.75% and 4.65%.

Historically, the Former Fund has maintained a constant $1.00 net asset value
per share. The bar chart shows the variability of the Former Fund's total
returns on a calendar year-end basis.

The Former Fund's Shares were not sold subject to a sales charge (load). The
total returns displayed above are based upon the net asset value.

The Former Fund's total return from January 1, 1999 to March 31, 1999 was 0.99%.

Within the period shown in the Chart, the Former Fund's highest quarterly return
was 1.32% (quarter ended June 30, 1995). Its lowest quarterly return was 0.61%
(quarter ended June 30, 1993).


Average Annual Total Return Table
The following table represents the Fund's Average Annual Total Returns for the
calendar periods ending December 31, 1998.

2  The adviser expects to voluntarily waive a portion of the management fee. The
   adviser can terminate this anticipated voluntary waiver at any time. The
   management fee paid by the Fund (after the anticipated voluntary waiver) is
   expected to be 0.24% for the fiscal year ended April 30, 2000.

   termiminate this anticipated voluntary reduction at any time. The shareholder
   services fee paid by the Fund (after the anticipated voluntary reduction) is
   expected to be 0.22% for the fiscal year ending April 30, 2000.

   Market Obligations Trust, the Total Annual Fund Operating Expenses and Total
   Actual Annual Fund Operating Expenses (after waivers) were 0.89% and 0.59%,
   respectively.



Example
The following Example is intended to help you compare the cost of investing in
the Fund's Shares with the cost of investing in other mutual funds.
  The Example assumes that you invest $10,000 in the Fund's Shares for the time
periods indicated and then redeem all of your Shares at the end of those
periods. The Example also assumes that your investment has a 5% return each year
and that the Fund's Shares operating expenses are before waivers as estimated in
the table and remain the same. Although your actual costs may be higher or
lower, based on these assumptions your costs would be:

Fund    1 Year       3 Years        5 Years       10 Years
           $90          $281           $488         $1,084



<PAGE>



WHAT ARE THE FUND'S INVESTMENT STRATEGIES?
The Fund invests only in a portfolio of U.S. Treasury securities maturing in 397
days or less. The dollar-weighted average maturity of the Fund's portfolio will
be 90 days or less.

The adviser targets a dollar-weighted average portfolio maturity range based
upon its interest rate outlook. The adviser formulates its interest rate outlook
by analyzing a variety of factors, such as:

o........current U.S. economic activity and the economic outlook,

o        current short-term interest rates,

o    the Federal Reserve Board's policies regarding  short-term  interest rates,
     and

o    the  potential  effects of foreign  economic  activity  on U.S.  short-term
     interest rates.

The adviser generally shortens the portfolio's dollar-weighted average maturity
when it expects interest rates to rise and extends the maturity when it expects
interest rates to fall. The adviser selects securities used to lengthen or
shorten the portfolio's dollar-weighted average maturity by comparing the
returns currently offered by different investments to their historical and
expected returns.


WHAT ARE THE PRINCIPAL SECURITIES IN WHICH THE FUND INVESTS?

U.S. Treasury Securities

U.S. Treasury securities are direct obligations of the federal government of the
United States. U.S. Treasury securities pay interest, dividends or distributions
at a specified  rate.  The rate may be a fixed  percentage  of the  principal or
adjusted  periodically.  In addition, the U.S. Treasury must repay the principal
amount of the security, normally within a specified time.


WHAT ARE THE SPECIFIC RISKS OF INVESTING IN THE FUND?

Although there are many factors that may affect an investment in the Fund, the
principal risk of investing in a U.S. Treasury money market fund is described
below.

Interest Rate Risks

Prices of fixed income securities rise and fall in response to changes in the
interest rate paid by similar securities. Generally, when interest rates rise,
prices of fixed income securities fall. However, market factors, such as the
demand for particular fixed income securities, may cause the price of certain
fixed income securities to fall while the prices of other securities rise or
remain unchanged.

Interest rate changes have a greater effect on the price of fixed income
securities with longer maturities. Money market funds try to minimize this risk
by purchasing short-term securities.


WHAT DO SHARES COST?

You can purchase or redeem Shares any day the New York Stock Exchange (NYSE) is
open. The Fund attempts to stabilize the net asset value (NAV) of its Shares at
$1.00 by valuing the portfolio securities using the amortized cost method. The
Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The
Fund does not charge a front-end sales charge. NAV is determined at 12:00 noon
and 1:00 p.m. (Eastern time) and as of the end of regular trading (normally 4:00
p.m. Eastern time) each day the NYSE is open.

The required minimum initial investment for Fund Shares is $25,000. There is no
required minimum subsequent investment amount.

An account may be opened with a smaller amount as long as the $25,000 minimum is
reached within 90 days. An institutional investor's minimum investment is
calculated by combining all accounts it maintains with the Fund. Accounts
established through investment professionals may be subject to a smaller minimum
investment amount. Keep in mind that investment professionals may charge you
fees for their services in connection with your Share transactions.


HOW IS THE FUND SOLD?

The Fund's Distributor markets the Shares described in this prospectus to
institutional investors, such as banks, fiduciaries, custodians of public funds,
corporations, unions, hospitals, insurance companies and municipalities, or
individuals, directly or through investment professionals.

The  Distributor  and its  affiliates  may pay out of their assets other amounts
(including  items of material value) to investment  professionals  for marketing
and servicing  Shares.  The Distributor is a subsidiary of Federated  Investors,
Inc. (Federated).

o wire payment to your account at a domestic commercial bank that is a Federal
Reserve System member.


Redemption in Kind
Although the Fund intends to pay Share redemptions in cash, it reserves the
right to pay the redemption price in whole or in part by a distribution of the
Fund's portfolio securities.


LIMITATIONS ON REDEMPTION PROCEEDS
Redemption proceeds normally are wired or mailed within one business day after
receiving a request in proper form. Payment may be delayed up to seven days:

o        to allow your purchase to clear;

o        during periods of market volatility; or

o when a shareholder's trade activity or amount adversely impacts the Fund's
ability to manage its assets.

You will not accrue interest or dividends on uncashed checks from the Fund if
those checks are undeliverable and returned to the Fund.


REDEMPTIONS FROM RETIREMENT ACCOUNTS
In the absence of your specific instructions, 10% of the value of your
redemption from a retirement account in the Fund may be withheld for taxes. This
withholding only applies to certain types of retirement accounts.


ADDITIONAL CONDITIONS

Telephone Transactions
The Fund will record your telephone instructions. If the Fund does not follow
reasonable procedures, it may be liable for losses due to unauthorized or
fraudulent telephone instructions.


Share Certificates
The Fund no longer issues share certificates. If you are redeeming Shares
represented by certificates previously issued by the Fund, you must return the
certificates with your written redemption request. For your protection, send
your certificates by registered or certified mail, but do not endorse them.

ACCOUNT AND SHARE INFORMATION


Account Activity
You will receive periodic statements reporting all account activity, including
dividends and capital gains paid.


DIVIDENDS AND CAPITAL GAINS
The Fund declares any dividends daily and pays them monthly to shareholders. If
you purchase Shares by wire, you begin earning dividends on the day your wire is
received. If you purchase Shares by check, you begin earning dividends on the
business day after the Fund receives your check. In either case, you earn
dividends through the day your redemption request is received.

The Fund does not expect to realize any capital gains or losses. If capital
gains or losses were to occur, they could result in an increase or decrease in
dividends. The Fund pays any capital gains at least annually. Your dividends and
capital gains distributions will be automatically reinvested in additional
Shares without a sales charge, unless you elect cash payments.


ACCOUNTS WITH LOW BALANCES
Due to the high cost of maintaining accounts with low balances, non-retirement
accounts may be closed if redemptions cause the account balance to fall below
the minimum initial investment amount. Before an account is closed, you will be
notified and allowed 30 days to purchase additional Shares to meet the minimum.


TAX INFORMATION
The Fund sends an annual statement of your account activity to assist you in
completing your federal, state and local tax returns. Fund distributions of
dividends and capital gains are taxable to you whether paid in cash or
reinvested in the Fund. Dividends are taxable as ordinary income; capital gains
are taxable at different rates depending upon the length of time the Fund holds
its assets.

Fund distributions are expected to be primarily dividends. Redemptions are
taxable sales. Please consult your tax adviser regarding your federal, state,
and local tax liability.


WHO MANAGES THE FUND?

The Board of Trustees governs the Fund. The Board selects and oversees the
Adviser, Federated Investment Management Company. The Adviser manages the Fund's
assets, including buying and selling portfolio securities. The Adviser's address
is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 175 mutual
funds and separate accounts, which total approximately $111 billion in assets as
of December 31, 1998. Federated was established in 1955 and is one of the
largest mutual fund investment managers in the United States with approximately
1,900 employees. More than 4,000 investment professionals make Federated Funds
available to their customers.


Advisory Fees
The Adviser receives an annual investment advisory fee of 0.50% of the Fund's
average daily net assets. The Adviser may voluntarily waive a portion of its fee
or reimburse the Fund for certain operating expenses.


Year 2000 Readiness
The "Year 2000" problem is the potential for computer errors or failures because
certain computer systems may be unable to interpret dates after December 31,
1999. The Year 2000 problem may cause systems to process information incorrectly
and could disrupt businesses, such as the Fund, that rely on computers.

While it is impossible to determine in advance all of the risks to the Fund, the
Fund could experience interruptions in basic financial and operational
functions. Fund shareholders could experience errors or disruptions in Fund
share transactions or Fund communications.

The Fund's service providers are making changes to their computer systems to fix
any Year 2000 problems. In addition, they are working to gather information from
third-party providers to determine their Year 2000 readiness.

Year 2000 problems would also increase the risks of the Fund's investments. To
assess the potential effect of the Year 2000 problem, the Adviser is reviewing
information regarding the Year 2000 readiness of issuers of securities the Fund
may purchase. The financial impact of these issues for the Fund is still being
determined. There can be no assurance that potential Year 2000 problems would
not have a material adverse effect on the Fund.

HOW IS THE FUND ORGANIZED?

The Fund is a diversified portfolio of Money Market Obligations Trust (Trust).
The Trust is an open-end, management investment company that was established
under the laws of the Commonwealth of Massachusetts on October 3, 1988. The
Trust may offer separate series of shares representing interests in separate
portfolios of securities. The Fund, which was established on December 7, 1989,
was reorganized as a portfolio of the Trust on July ____, 1999. The Fund's
investment adviser is Federated Investment Management Company.


SECURITIES IN WHICH THE FUND INVESTS

In pursuing its investment strategy, the Fund may invest in the following
securities for any purpose that is consistent with its investment objective.


SECURITIES DESCRIPTIONS AND TECHNIQUES
Fixed Income Securities

Fixed income securities pay interest, dividends or distributions at a specified
rate. The rate may be a fixed percentage of the principal or adjusted
periodically. In addition, the issuer of a fixed income security must repay the
principal amount of the security, normally within a specified time. Fixed income
securities provide more regular income than equity securities. However, the
returns on fixed income securities are limited and normally do not increase with
the issuer's earnings. This limits the potential appreciation of fixed income
securities as compared to equity securities.

A security's yield measures the annual income earned on a security as a
percentage of its price. A security's yield will increase or decrease depending
upon whether it costs less (a discount) or more (a premium) than the principal
amount. If the issuer may redeem the security before its scheduled maturity, the
price and yield on a discount or premium security may change based upon the
probability of an early redemption. Securities with higher risks generally have
higher yields.

The following describes the types of fixed income securities in which the Fund
invests.

     Treasury Securities
     Treasury  securities are direct  obligations of the federal  government of
          the United  States.  Treasury  securities are generally
     regarded as having the lowest credit risks.
     Zero Coupon Securities

     Zero coupon securities do not pay interest or principal until final
     maturity unlike debt securities that provide periodic payments of interest
     (referred to as a coupon payment). Investors buy zero coupon securities at
     a price below the amount payable at maturity. The difference between the
     purchase price and the amount paid at maturity represents interest on the
     zero coupon security. Investors must wait until maturity to receive
     interest and principal, which increases the interest rate risks and credit
     risks of a zero coupon security.

     There are many forms of zero coupon securities. Some are issued at a
     discount and are referred to as zero coupon or capital appreciation bonds.
     Others are created from interest bearing bonds by separating the right to
     receive the bond's coupon payments from the right to receive the bond's
     principal due at maturity, a process known as coupon stripping. In
     addition, some securities give the issuer the option to deliver additional
     securities in place of cash interest payments, thereby increasing the
     amount payable at maturity. These are referred to as pay-in-kind or PIK
     securities.



<PAGE>


Special Transactions
     Delayed Delivery Transactions
     Delayed delivery transactions, including when issued transactions, are
     arrangements in which the Fund buys securities for a set price, with
     payment and delivery of the securities scheduled for a future time. During
     the period between purchase and settlement, no payment is made by the Fund
     to the issuer and no interest accrues to the Fund. The Fund records the
     transaction when it agrees to buy the securities and reflects their value
     in determining the price of its shares. Settlement dates may be a month or
     more after entering into these transactions so that the market values of
     the securities bought may vary from the purchase prices. Therefore, delayed
     delivery transactions create interest rate risks for the Fund. Delayed
     delivery transactions also involve credit risks in the event of a
     counterparty default. Asset Coverage In order to secure its obligations in
     connection with special transactions, the Fund will either own the
     underlying assets, enter into an offsetting transaction or set aside
     readily marketable securities with a value that equals or exceeds the
     Fund's obligations. Unless the Fund has other readily marketable assets to
     set aside, it cannot trade assets used to secure such obligations without
     terminating a special transaction. This may cause the Fund to miss
     favorable trading opportunities or to realize losses on special
     transactions.

INVESTMENT RISKS
There are many factors which may affect an investment in the Fund. The Fund's
principal risks are described in its prospectus. Additional risk factors are
outlined below.

Credit Risk
Credit risk is the possibility that an issuer will default on a security by
failing to pay interest or principal when due. If an issuer defaults, the Fund
will lose money.

Credit risk includes the possibility that a party to a transaction involving the
Fund will fail to meet its obligations. This could cause the Fund to lose the
benefit of the transaction or prevent the Fund from selling or buying other
securities to implement its investment strategy.

INVESTMENT LIMITATIONS

Diversification

With respect to securities comprising 75% of the value of its total assets, the
Fund will not purchase securities of any one issuer (other than cash; cash
items; securities issued or guaranteed by the government of the United States or
its agencies or instrumentalities and repurchase agreements collateralized by
such U.S. government securities; and securities of other investment companies)
if, as a result, more than 5% of the value of its total assets would be invested
in securities of that issuer, or the Fund would own more than 10% of the
outstanding voting securities of that issuer.

Concentration

The Fund will not make investments that will result in the concentration of its
investments in the securities of issuers primarily engaged in the same industry.
Government securities, municipal securities and bank instruments are not deemed
to constitute an industry.





<PAGE>


Issuing Senior Securities and Borrowing Money

The Fund may borrow money, directly or indirectly, and issue senior securities
to the maximum extent permitted under the 1940 Act.

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 pledge.

Lending Cash or Securities

The Fund will not lend any of its assets, except that it may purchase or hold
U.S. Treasury obligations, as permitted by its investment objective, policies,
and limitations or Declaration of Trust.

Investing in Real Estate

The Fund may not purchase or sell real estate, provided that this restriction
does not prevent the Fund from investing in issuers which invest, deal, or
otherwise engage in transactions in real estate or interests therein, or
investing in securities that are secured by real estate or interests therein.
The Fund may exercise its rights under agreements relating to such securities,
including the right to enforce security interests and to hold real estate
acquired by reason of such enforcement until that real estate can be liquidated
in an orderly manner.

Underwriting Securities

The Fund may not underwrite the securities of other issuers, except that the
Fund may engage in transactions involving the acquisition, disposition or resale
of its portfolio securities, under circumstances where it may be considered to
be an underwriter under the Securities Act of 1933.

Investing in Commodities

The Fund may not purchase or sell physical commodities, provided that the Fund
may purchase securities of companies that deal in commodities.

The above limitations cannot be changed unless authorized by the "vote of a
majority of its outstanding voting securities," as defined by the Investment
Company Act. The following limitations, however, may be changed by the Board
without shareholder approval. Shareholders will be notified before any material
change in these limitations becomes effective.

Buying on Margin

The Fund will not purchase securities on margin, provided that the Fund may
obtain short-term credits necessary for the clearance of purchases and sales of
securities.

Investing in Illiquid Securities

The Fund will not purchase securities for which there is no readily available
market, or enter into repurchase agreements or purchase time deposits maturing
in more than seven days, if immediately after and as a result, the value of such
securities would exceed, in the aggregate, 10% of the Fund's net assets.

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.

For purposes of the above policy concerning concentration, in conformity with an
SEC position, the Fund considers "bank instruments" to be limited to instruments
of domestic banks.

For purposes of the above limitations, the Fund considers certificates of
deposit and demand and time deposits issued by a U.S. branch of a domestic bank
or savings association having capital, surplus, and undivided profits in excess
of $100,000,000 at the time of investment to be "cash items." Except with
respect to borrowing money, if a percentage limitation is adhered to at the time
of 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 limitation.



<PAGE>


Regulatory Compliance

The Fund may follow non-fundamental operational policies that are more
restrictive than its fundamental investment limitations, as set forth in the
prospectus and this Statement of Additional Information, in order to comply with
applicable laws and regulations, including the provisions of and regulations
under the Investment Company Act of 1940. In particular, the Fund will comply
with the various requirements of Rule 2a-7 (the "Rule"), which regulates money
market mutual funds. The Fund will determine the effective maturity of its
investments according to the Rule. The Fund may change these operational
policies to reflect changes in the laws and regulations without the approval of
its shareholders.


DETERMINING MARKET VALUE OF SECURITIES

The Trustees have decided that the best method for determining the value of
portfolio instruments is amortized cost. Under this method, portfolio
instruments are valued at the acquisition cost as adjusted for amortization of
premium or accumulation of discount rather than at current market value.
Accordingly, neither the amount of daily income nor the net asset value is
affected by any unrealized appreciation or depreciation of the portfolio. In
periods of declining interest rates, the indicated daily yield on shares of the
Fund computed by dividing the annualized daily income on the Fund's portfolio by
the net asset value computed as above may tend to be higher than a similar
computation made by using a method of valuation based upon market prices and
estimates. In periods of rising interest rates, the opposite may be true.

The Fund's use of the amortized cost method of valuing portfolio instruments
depends on its compliance with certain conditions in the Rule. Under the Rule,
the Trustees must establish procedures reasonably designed to stabilize the net
asset value per share, as computed for purposes of distribution and redemption,
at $1.00 per share, taking into account current market conditions and the Fund's
investment objective. The procedures include monitoring the relationship between
the amortized cost value per share and the net asset value per share based upon
available indications of market value. The Trustees will decide what, if any,
steps should be taken if there is a difference of more than 0.5 of 1% between
the two values. The Trustees will take any steps they consider appropriate (such
as redemption in kind or shortening the average portfolio maturity) to minimize
any material dilution or other unfair results arising from differences between
the two methods of determining net asset value.




HOW IS THE FUND SOLD?

Under the  Distributor's  Contract  with the Fund,  the  Distributor  (Federated
Securities Corp.) offers Shares on a continuous, best-efforts basis.


SHAREHOLDER SERVICES
The Fund may pay Federated Shareholder Services Company, a subsidiary of
Federated Investors, Inc. (Federated), for providing shareholder services and
maintaining shareholder accounts. Federated Shareholder Services Company may
select others to perform these services for their customers and may pay them
fees.


SUPPLEMENTAL PAYMENTS
Investment professionals may be paid fees out of the assets of the Distributor
and/or Federated Shareholder Services Company (but not out of Fund assets). The
Distributor and/or Federated Shareholder Services Company may be reimbursed by
the Adviser or its affiliates.

Investment professionals receive such fees for providing distribution-related or
shareholder services such as sponsoring sales, providing sales literature,
conducting training seminars for employees, and engineering sales-related
computer software programs and systems. Also, investment professionals may be
paid cash or promotional incentives, such as reimbursement of certain expenses
relating to attendance at informational meetings about the Fund or other special
events at recreational-type facilities, or items of material value. These
payments will be based upon the amount of Shares the investment professional
sells or may sell and/or upon the type and nature of sales or marketing support
furnished by the investment professional.


SUBACCOUNTING SERVICES

Certain investment professionals may wish to use the transfer agent's
subaccounting system to minimize their internal recordkeeping requirements. The
transfer agent may charge a fee based on the level of subaccounting services
rendered. Investment professionals holding Shares in a fiduciary, agency,
custodial, or similar capacity may charge or pass through subaccounting fees as
part of or in addition to normal trust or agency account fees. They may also
charge fees for other services that may be related to the ownership of Shares.
This information should, therefore, be read together with any agreement between
the customer and the investment professional about the services provided, the
fees charged for those services, and any restrictions and limitations imposed.


REDEMPTION IN KIND

Although the Fund intends to pay Share redemptions in cash, it reserves the
right, as described below, to pay the redemption price in whole or in part by a
distribution of the Fund's portfolio securities.

Because the Fund has elected to be governed by Rule 18f-1 under the Investment
Company Act of 1940, the Fund is obligated to pay Share redemptions to any one
shareholder in cash only up to the lesser of $250,000 or 1% of the net assets
represented by such Share class during any 90-day period.

Any Share redemption payment greater than this amount will also be in cash
unless the Fund's Board determines that payment should be in kind. In such a
case, the Fund will pay all or a portion of the remainder of the redemption in
portfolio securities, valued in the same way as the Fund determines its NAV. The
portfolio securities will be selected in a manner that the Fund's Board deems
fair and equitable and, to the extent available, such securities will be readily
marketable.

Redemption in kind is not as liquid as a cash redemption. If redemption is made
in kind, shareholders receiving the portfolio securities and selling them before
their maturity could receive less than the redemption value of the securities
and could incur certain transaction costs.


MASSACHUSETTS PARTNERSHIP LAW

Under certain circumstances, shareholders may be held personally liable as
partners under Massachusetts law for obligations of the Trust. To protect its
shareholders, the Trust has filed legal documents with Massachusetts that
expressly disclaim the liability of its shareholders for acts or obligations of
the Trust.

In the unlikely event a shareholder is held personally liable for the Trust's
obligations, the Trust is required by the Declaration of Trust to use its
property to protect or compensate the shareholder. On request, the Trust will
defend any claim made and pay any judgment against a shareholder for any act or
obligation of the Trust. Therefore, financial loss resulting from liability as a
shareholder will occur only if the Trust itself cannot meet its obligations to
indemnify shareholders and pay judgments against them.


ACCOUNT AND SHARE INFORMATION


VOTING RIGHTS
Each share of the Fund gives the shareholder one vote in Trustee elections and
other matters submitted to shareholders for vote.

 All Shares of the Trust have equal voting rights, except that in matters
affecting only a particular Fund or class, only Shares of that Fund or class are
entitled to vote.

Trustees may be removed by the Board or by shareholders at a special meeting. A
special meeting of shareholders will be called by the Board upon the written
request of shareholders who own at least 10% of the Trust's outstanding shares
of all series entitled to vote.

As of ___________, the following shareholders owned of record beneficially, or
both, 5% or more of outstanding Shares:


TAX INFORMATION


FEDERAL INCOME TAX
The Fund intends to meet requirements of Subchapter M of the Internal Revenue
Code applicable to regulated investment companies. If these requirements are not
met, it will not receive special tax treatment and will pay federal income tax.

The Fund will be treated as a single, separate entity for federal income tax
purposes so that income earned and capital gains and losses realized by the
Trust's other portfolios will be separate from those realized by the Fund.


WHO MANAGES AND PROVIDES SERVICES TO THE FUND?


BOARD OF TRUSTEES
The Board is responsible for managing the Trust's business affairs and for
exercising all the Trust's powers except those reserved for the shareholders.
Information about each Board member is provided below and includes each
person's: name, address, birth date, present position(s) held with the Trust,
principal occupations for the past five years and positions held prior to the
past five years, total compensation received as a Trustee from the Trust for its
most recent fiscal year, and the total compensation received from the Federated
Fund Complex for the most recent calendar year. The Trust is comprised of
fifteen Funds and the Federated Fund Complex is comprised of 56 investment
companies, whose investment advisers are affiliated with the Trust's Adviser.

As of ___________, 1999, the Fund's Board and Officers as a group owned less
than 1% of the Fund's outstanding shares.

An asterisk (*) denotes a Trustee who is deemed to be an interested person as
defined in the Investment Company Act of 1940. The following symbol (#) denotes

INVESTMENT ADVISER
The Adviser conducts investment research and makes investment decisions for the
Fund.

The Adviser is a wholly-owned subsidiary of Federated.

The Adviser shall not be liable to the Trust or any Fund 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 Trust.


Other Related Services
Affiliates of the Adviser may, from time to time, provide certain electronic
equipment and software to institutional customers in order to facilitate the
purchase of Fund Shares offered by the Distributor.


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. 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. In selecting among firms believed to meet these
criteria, the Adviser may give consideration to those firms which have sold or
are selling Shares of the Fund and other funds distributed by the Distributor
and its affiliates. The Adviser makes decisions on portfolio transactions and
selects brokers and dealers subject to review by the Fund's Board.


Research Services
Investment decisions for the Fund are made independently from those of other
accounts managed by the Adviser. When the Fund and one or more of those accounts
invests in, or disposes of, the same security, available investments or
opportunities for sales will be allocated among the Fund and the account(s) in a
manner believed by the Adviser to be equitable. While the coordination and
ability to participate in volume transactions may benefit the Fund, it is
possible that this procedure could adversely impact the price paid or received
and/or the position obtained or disposed of by the Fund.

HOW DOES THE FUND MEASURE PERFORMANCE?

The Fund may advertise Share performance by using the Securities and Exchange
Commission's (SEC) standard method for calculating performance applicable to all
mutual funds. The SEC also permits this standard performance information to be
accompanied by non-standard performance information.

Unless otherwise stated, any quoted Share performance reflects the effect of
non-recurring charges, such as maximum sales charges, which, if excluded, would
increase the total return and yield. The performance of Shares depends upon such
variables as: portfolio quality; average portfolio maturity; type and value of
portfolio securities; changes in interest rates; changes or differences in the
Fund's or any class of Shares' expenses; and various other factors.

Share performance fluctuates on a daily basis largely because net earnings
fluctuate daily. Both net earnings and offering price per Share are factors in
the computation of yield and total return.

- -------------------------------------------------------------------------------

TOTAL RETURN
Total return represents the change (expressed as a percentage) in the value of
Shares over a specific period of time, and includes the investment of income and
capital gains distributions.

The average annual total return for Shares 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 NAV 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 the annual reinvestment of all
dividends and distributions.


YIELD
The yield of Shares is based upon the seven days ending on the day of the
calculation, called the "base period." This yield is calculated by: determining
the net change in the value of a hypothetical account with a balance of one
Share at the beginning of the base period, with the net change excluding capital
changes but including the value of any additional Shares purchased with
dividends earned from the original one Share and all dividends declared on the
original and any purchased Shares; dividing the net change in the account's
value by the value of the account at the beginning of the base period to
determine the base period return; and multiplying the base period return by
365/7. The effective yield is calculated by compounding the unannualized
base-period return by: adding one to the base-period return, raising the sum to
the 365/7th power; and subtracting one from the result.

To the extent investment professionals and broker/dealers charge fees in
connection with services provided in conjunction with an investment in Shares,
the Share performance is lower for shareholders paying those fees.




PERFORMANCE COMPARISONS
Advertising and sales literature may include:

o........references  to ratings,  rankings,  and financial  publications  and/or
     performance comparisons of Shares to certain indices;

o  charts, graphs and illustrations using the Fund's returns, or returns in

in which it invests, to a variety of other investments, including federally
insured bank products such as bank savings accounts, certificates of deposit,
and Treasury bills.

The Fund may quote information from reliable sources regarding individual

Risk/Return Bar Chart and Table
The Bar Chart and Performance Table below reflect historical performance data
for Institutional Shares of U.S. Treasury Cash Reserves (the "Former Fund")
prior to its reorganization into the Fund, which is a newly created portfolio of
Money Market Obligations Trust (the "Trust"). On the date of the reorganization,
________, 1999, the Former Fund was dissolved and its net assets (inclusive of
liabilities recorded on the Former Fund's records) were transferred to the Fund.

The graphic presentation displayed here consists of a bar chart representing the
annual total returns of the Former Fund's Institutional Shares as of the
calendar year-end for each of seven years.

The `y' axis reflects the "% Total Return" beginning with "0" and increasing in
increments of 1% up to 6%.

The `x' axis represents calculation periods from the earliest first full
calendar year end of the Former Fund's start of business through the calendar
year ended December 31, 1998. The light gray shaded chart features seven
distinct vertical bars, each shaded in charcoal, and each visually representing

   adviser can terminate this anticipated voluntary waiver at any time. The
   management fee paid by the Fund (after the anticipated voluntary waiver) is
   expected to be 0.10% for the fiscal year ending April 30, 2000.

   Fee paid (after the anticipated voluntary waiver) is expected to be 0.00% for
   the fiscal year ending April 30, 2000.

   Annual Fund Operating Expenses (after waivers) for the Former Fund's
   Institutional Shares were 0.75% and 0.20%, respectively.


Example
The following Example is intended to help you compare the cost of investing in
the Fund's Institutional Shares with the cost of investing in other mutual
funds.
  The Example assumes that you invest $10,000 in the Fund's Institutional Shares
for the time periods indicated and then redeem all of your Shares at the end of
those periods. The Example also assumes that your investment has a 5% return
each year and that the Fund's Institutional Shares operating expenses are before
waivers as estimated in the table and remain the same. Although your actual
costs may be higher or lower, based on these assumptions your costs would be:
                       1 Year       3 Years        5 Years       10 Years
Institutional Shares      $78          $243           $422           $942



<PAGE>



WHAT ARE THE FUND'S INVESTMENT STRATEGIES?
The Fund invests only in a portfolio of U.S. Treasury securities maturing in 397
days or less. The dollar-weighted average maturity of the Fund's portfolio will
be 90 days or less.

The adviser targets a dollar-weighted average portfolio maturity range based
upon its interest rate outlook. The adviser formulates its interest rate outlook
by analyzing a variety of factors, such as:

o........current U.S. economic activity and the economic outlook,

o        current short-term interest rates,

o    the Federal Reserve Board's policies regarding  short-term  interest rates,
     and

o    the  potential  effects of foreign  economic  activity  on U.S.  short-term
     interest rates.

The adviser generally shortens the portfolio's dollar-weighted average maturity
when it expects interest rates to rise and extends the maturity when it expects
interest rates to fall. The adviser selects securities used to lengthen or
shorten the portfolio's dollar-weighted average maturity by comparing the
returns currently offered by different investments to their historical and
expected returns.


WHAT ARE THE PRINCIPAL SECURITIES IN WHICH THE FUND INVESTS?
U.S. Treasury Securities

U.S. Treasury securities are direct obligations of the federal government of the
United States. U.S. Treasury securities pay interest, dividends or distributions
at a specified  rate.  The rate may be a fixed  percentage  of the  principal or
adjusted  periodically.  In addition, the U.S. Treasury must repay the principal
amount of the security, normally within a specified time.


WHAT ARE THE SPECIFIC RISKS OF INVESTING IN THE FUND?
Although there are many factors that may affect an investment in the Fund, the
principal risk of investing in a U.S. Treasury money market fund is described
below.

Interest Rate Risks

Prices of fixed income securities rise and fall in response to changes in the
interest rate paid by similar securities. Generally, when interest rates rise,
prices of fixed income securities fall. However, market factors, such as the
demand for particular fixed income securities, may cause the price of certain
fixed income securities to fall while the prices of other securities rise or
remain unchanged.

Interest rate changes have a greater effect on the price of fixed income
securities with longer maturities. Money market funds try to minimize this risk
by purchasing short-term securities.


WHAT DO SHARES COST?

You can purchase or redeem Shares any day the New York Stock Exchange (NYSE) is
open. The Fund attempts to stabilize the net asset value (NAV) of its Shares at
$1.00 by valuing the portfolio securities using the amortized cost method. The
Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The
Fund does not charge a front-end sales charge. NAV is determined at 12:00 noon
and 1:00 p.m. (Eastern time) and as of the end of regular trading (normally 4:00
p.m. Eastern time) each day the NYSE is open.

The required minimum initial investment for Fund Shares is $25,000. There is no
required minimum subsequent investment amount.

An account may be opened with a smaller amount as long as the $25,000 minimum is
reached within 90 days. An institutional investor's minimum investment is
calculated by combining all accounts it maintains with the Fund. Accounts
established through investment professionals may be subject to a smaller minimum
investment amount. Keep in mind that investment professionals may charge you
fees for their services in connection with your Share transactions.


HOW IS THE FUND SOLD?

The Fund offers two share classes: Institutional Shares and Institutional
Service Shares, each representing interests in a single portfolio of securities.
This prospectus relates only to Institutional Shares. Each share class has
different expenses, which affect their performance. Contact your investment
professional or call 1-800-341-7400 for more information concerning the other
class.

The Fund's Distributor markets the Shares described in this prospectus to
institutional investors, such as banks, fiduciaries, custodians of public funds,
corporations, unions, hospitals, insurance companies and municipalities, or
individuals, directly or through investment professionals.

The  Distributor  and its  affiliates  may pay out of their assets other amounts
(including  items of material value) to investment  professionals  for marketing
and servicing  Shares.  The Distributor is a subsidiary of Federated  Investors,
Inc. (Federated).


HOW TO PURCHASE SHARES

You may purchase Shares through an investment professional or directly from the
Fund. The Fund reserves the right to reject any request to purchase Shares.


THROUGH AN INVESTMENT PROFESSIONAL
o        Establish an account with the investment professional; and

o  Submit your purchase order to the investment professional before 2:00
   (Eastern time). You will receive that day's dividend if the investment
   professional forwards the order to the Fund and the Fund receives payment by
   2:00 (Eastern time). You will become the owner of Shares and receive
   dividends when the Fund receives your payment.

Investment professionals should send payments according to the instructions in
the sections "By Wire" or "By Check."


DIRECTLY FROM THE FUND

o    Establish  your account with the Fund by submitting a completed New Account
     Form; and

o        Send your payment to the Fund by Federal Reserve wire or check.

You will become the owner of Shares after the Fund receives your wire or your
check. If your check does not clear, your purchase will be canceled and you
could be liable for any losses or fees the Fund or its transfer agent incurs.

An institution may establish an account and place an order by calling the Fund
and will become a shareholder after the Fund receives the order.

HOW TO REDEEM SHARES

You should redeem Shares:

THROUGH AN INVESTMENT PROFESSIONAL
Submit your redemption request to your investment professional by the end of
regular trading on the NYSE (normally 4:00 p.m. Eastern time). Investment
professionals are responsible for promptly submitting redemption requests and
providing proper written redemption instructions as outlined below.

By Telephone
You may redeem Shares by calling the Fund once you have completed the
appropriate authorization form for telephone transactions.

If you call before 2:00 p.m. (Eastern time) your redemption will be wired to you
the same day. You will not receive that day's dividend.

If you call after 2:00 p.m. (Eastern time) your redemption will be wired to you
the following business day. You will receive that day's dividend.

   P.O. Box 8600
   Boston, MA 02266-8600
Send requests by private courier or overnight delivery service to:

   Federated Shareholder Services Company

     record;

o    your  redemption  will be sent to an  address  of record  that was  changed
     within the last 30 days; or

signature guarantee from a bank or trust company, savings association, credit
union or broker, dealer, or securities exchange member. A notary public cannot
provide a signature guarantee.


PAYMENT METHODS FOR REDEMPTIONS
Your redemption proceeds will be mailed by check to your address of record. The
following payment options are available if you complete the appropriate section
of the New Account Form or an Account Service Options Form. These payment
options require a signature guarantee if they were not established when the
account was opened:

o    an electronic  transfer to your account at a financial  institution that is
     an ACH member; or

o wire payment to your account at a domestic commercial bank that is a Federal
Reserve System member.


Redemption in Kind
Although the Fund intends to pay Share redemptions in cash, it reserves the
right to pay the redemption price in whole or in part by a distribution of the
Fund's portfolio securities.


LIMITATIONS ON REDEMPTION PROCEEDS
Redemption proceeds normally are wired or mailed within one business day after
receiving a request in proper form. Payment may be delayed up to seven days:

o        to allow your purchase to clear;

o        during periods of market volatility; or

o when a shareholder's trade activity or amount adversely impacts the Fund's
ability to manage its assets.

You will not accrue interest or dividends on uncashed checks from the Fund if
those checks are undeliverable and returned to the Fund.


ADDITIONAL CONDITIONS

Telephone Transactions
The Fund will record your telephone instructions. If the Fund does not follow
reasonable procedures, it may be liable for losses due to unauthorized or
fraudulent telephone instructions.


Share Certificates
The Fund no longer issues share certificates. If you are redeeming Shares
represented by certificates previously issued by the Fund, you must return the
certificates with your written redemption request. For your protection, send
your certificates by registered or certified mail, but do not endorse them.


ACCOUNT AND SHARE INFORMATION


Account Activity
You will receive periodic statements reporting all account activity, including
dividends and capital gains paid.


DIVIDENDS AND CAPITAL GAINS
The Fund declares any dividends daily and pays them monthly to shareholders. If
you purchase Shares by wire, you begin earning dividends on the day your wire is
received. If you purchase Shares by check, you begin earning dividends on the
business day after the Fund receives your check. In either case, you earn
dividends through the day your redemption request is received.

The Fund does not expect to realize any capital gains or losses. If capital
gains or losses were to occur, they could result in an increase or decrease in
dividends. The Fund pays any capital gains at least annually. Your dividends and
capital gains distributions will be automatically reinvested in additional
Shares without a sales charge, unless you elect cash payments.


ACCOUNTS WITH LOW BALANCES
Due to the high cost of maintaining accounts with low balances, accounts may be
closed if redemptions cause the account balance to fall below the minimum
initial investment amount. Before an account is closed, you will be notified and
allowed 30 days to purchase additional Shares to meet the minimum.


TAX INFORMATION
The Fund sends an annual statement of your account activity to assist you in
completing your federal, state and local tax returns. Fund distributions of
dividends and capital gains are taxable to you whether paid in cash or
reinvested in the Fund. Dividends are taxable as ordinary income; capital gains
are taxable at different rates depending upon the length of time the Fund holds
its assets.

Fund distributions are expected to be primarily dividends. Redemptions are
taxable sales. Please consult your tax adviser regarding your federal, state,
and local tax liability.


WHO MANAGES THE FUND?

The Board of Trustees governs the Fund. The Board selects and oversees the
Adviser, Federated Investment Management Company. The Adviser manages the Fund's
assets, including buying and selling portfolio securities. The Adviser's address
is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 175 mutual
funds and separate accounts, which total approximately $111 billion in assets as
of December 31, 1998. Federated was established in 1955 and is one of the
largest mutual fund investment managers in the United States with approximately
1,900 employees. More than 4,000 investment professionals make Federated Funds
available to their customers.


Advisory Fees
The Adviser receives an annual investment advisory fee of 0.40% of the Fund's
average daily net assets. The Adviser may voluntarily waive a portion of its fee
or reimburse the Fund for certain operating expenses.


Year 2000 Readiness
The "Year 2000" problem is the potential for computer errors or failures because
certain computer systems may be unable to interpret dates after December 31,
1999 or experience other date-related problems. The Year 2000 problem may cause
systems to process information incorrectly and could disrupt businesses, such as
the Fund, that rely on computers.

While it is impossible to determine in advance all of the risks to the Fund, the
Fund could experience interruptions in basic financial and operational
functions. Fund shareholders could experience errors or disruptions in Fund
share transactions or Fund communications.

The Fund's service providers are making changes to their computer systems to fix
any Year 2000 problems. In addition, they are working to gather information from
third-party providers to determine their Year 2000 readiness.

Year 2000 problems would also increase the risks of the Fund's investments. To
assess the potential effect of the Year 2000 problem, the Adviser is reviewing
information regarding the Year 2000 readiness of issuers of securities the Fund
may purchase. The financial impact of these issues for the Fund is still being
determined. There can be no assurance that potential Year 2000 problems would
not have a material adverse effect on the Fund.

Risk/Return Bar Chart and Table
The Bar Chart and Performance Table below reflect historical performance data
for Institutional Service Shares of U.S. Treasury Cash Reserves (the "Former
Fund") prior to its reorganization into the Fund, which is a newly created
portfolio of Money Market Obligations Trust (the "Trust"). On the date of the
reorganization, ________, 1999, the Former Fund was dissolved and its net assets
(inclusive of liabilities recorded on the Former Fund's records) were
transferred to the Fund.

The graphic presentation displayed here consists of a bar chart representing the
annual total returns of the Former Fund's Institutional Service Shares as of the
calendar year-end for each of four years.

The `y' axis reflects the "% Total Return" beginning with "0" and increasing in
increments of 1% up to 6%.

The `x' axis represents calculation periods from the earliest first full
calendar year end of the Former Fund's start of business through the calendar
year ended December 31, 1998. The light gray shaded chart features four distinct
vertical bars, each shaded in charcoal, and each visually representing by height
the total return percentages for the calendar year stated directly at its base.
The calculated total return percentage for the Former Fund's Institutional
Service Shares for each calendar year is stated directly at the top of each
respective bar, for the calendar years 1995 through 1998. The percentages noted
are: 5.34%, 4.86%, 4.91% and 4.79%.

Historically, the Former Fund has maintained a constant $1.00 net asset value
per share. The bar chart shows the variability of the Former Fund's
Institutional Service Shares total returns on a calendar year-end basis.

The Former Fund's Institutional Service Shares were not sold subject to a sales
charge (load). The total returns displayed above are based upon the net asset
value.

The Former Fund's Institutional Service Shares total return from January 1, 1999
to March 31, 1999 was 1.02%.

Within the period shown in the Chart, the Former Fund's Institutional Service
Shares highest quarterly return was 1.35% (quarter ended June 30, 1995). Its
lowest quarterly return was 1.08% (quarter ended December 31, 1998).


Average Annual Total Return Table
The following table represents the Fund's Institutional Service Shares Average
Annual Total Returns for the calendar periods ending December 31, 1998.

Calendar Period       Institutional Service

   the Distribution (12b-1) Fee at any time at its sole discretion. The
   Distribution (12b-1) Fee paid ( after the anticipated voluntary waiver) by
   the Fund is expected to be 0.00% for the fiscal year ending April 30, 2000.

4  For the fiscal year ended April 30, 1999, prior to the reorganization of U.S.
   Treasury Cash Reserves, the Former Fund, as a portfolio of Money Market
   Obligations Trust, the Total Annual Fund Operating Expenses and Total Actual
   Annual Fund Operating Expenses (after waivers) for Institutional Service
   Shares was 1.00% and 0.45%, respectively.

Example
The following Example is intended to help you compare the cost of investing in
the Fund's Institutional Service Shares with the cost of investing in other
mutual funds.
  The Example assumes that you invest $10,000 in the Fund's Institutional
Service Shares for the time periods indicated and then redeem all of your Shares
at the end of those periods. The Example also assumes that your investment has a
5% return each year and that the Fund's Institutional Service Shares operating
expenses are before waivers as estimated in the table and remain the same.
Although your actual costs may be higher or lower, based on these assumptions
your costs would be:
                               1 Year       3 Years        5 Years      10 Years

<PAGE>



WHAT ARE THE FUND'S INVESTMENT STRATEGIES?

The Fund invests only in a portfolio of U.S. Treasury securities maturing in 397
days or less. The dollar-weighted average maturity of the Fund's portfolio will
be 90 days or less.

The adviser targets a dollar-weighted average portfolio maturity range based
upon its interest rate outlook. The adviser formulates its interest rate outlook
by analyzing a variety of factors, such as:

o........current U.S. economic activity and the economic outlook,

o        current short-term interest rates,

o    the Federal Reserve Board's policies regarding  short-term  interest rates,
     and

o    the  potential  effects of foreign  economic  activity  on U.S.  short-term
     interest rates.

The adviser generally shortens the portfolio's dollar-weighted average maturity
when it expects interest rates to rise and extends the maturity when it expects
interest rates to fall. The adviser selects securities used to lengthen or
shorten the portfolio's dollar-weighted average maturity by comparing the
returns currently offered by different investments to their historical and
expected returns.


WHAT ARE THE PRINCIPAL SECURITIES IN WHICH THE FUND INVESTS?
U.S. Treasury Securities

U.S. Treasury securities are direct obligations of the federal government of the
United States. U.S. Treasury securities pay interest, dividends or distributions
at a specified  rate.  The rate may be a fixed  percentage  of the  principal or
adjusted  periodically.  In addition, the U.S. Treasury must repay the principal
amount of the security, normally within a specified time.


WHAT ARE THE SPECIFIC RISKS OF INVESTING IN THE FUND?
Although there are many factors that may affect an investment in the Fund, the
principal risk of investing in a U.S. Treasury money market fund is described
below.

Interest Rate Risks

Prices of fixed income securities rise and fall in response to changes in the
interest rate paid by similar securities. Generally, when interest rates rise,
prices of fixed income securities fall. However, market factors, such as the
demand for particular fixed income securities, may cause the price of certain
fixed income securities to fall while the prices of other securities rise or
remain unchanged.

Interest rate changes have a greater effect on the price of fixed income
securities with longer maturities. Money market funds try to minimize this risk
by purchasing short-term securities.


WHAT DO SHARES COST?

You can purchase or redeem Shares any day the New York Stock Exchange (NYSE) is
open. The Fund attempts to stabilize the net asset value (NAV) of its Shares at
$1.00 by valuing the portfolio securities using the amortized cost method. The
Fund cannot guarantee that its NAV will always remain at $1.00 per Share. The
Fund does not charge a front-end sales charge. NAV is determined at 12:00 noon
and 1:00 p.m. (Eastern time) and as of the end of regular trading (normally 4:00
p.m. Eastern time) each day the NYSE is open.

The required minimum initial investment for Fund Shares is $25,000. There is no
required minimum subsequent investment amount.

An account may be opened with a smaller amount as long as the $25,000 minimum is
reached within 90 days. An institutional investor's minimum investment is
calculated by combining all accounts it maintains with the Fund. Accounts
established through investment professionals may be subject to a smaller minimum
investment amount. Keep in mind that investment professionals may charge you
fees for their services in connection with your Share transactions.


HOW IS THE FUND SOLD?

The Fund offers two share classes: Institutional Service Shares and
Institutional Shares, each representing interests in a single portfolio of
securities. This prospectus relates only to Institutional Service Shares. Each
share class has different expenses, which affect their performance. Contact your
investment professional or call 1-800-341-7400 for more information concerning
the other class.

The Fund's Distributor markets the Shares described in this prospectus to
accounts for which financial institutions act in an agency or fiduciary
capacity, or individuals, directly or through investment professionals.

When the Distributor receives marketing fees, it may pay some or all of them to
investment professionals. The Distributor and its affiliates may pay out of
their assets other amounts (including items of material value) to investment
professionals for marketing and servicing Shares. The Distributor is a
subsidiary of Federated Investors, Inc. (Federated).


RULE 12B-1 PLAN
The Fund has adopted a Rule 12b-1 Plan, which allows it to pay marketing fees to
the Distributor and investment professionals for the sale, distribution and
customer servicing of the Fund's Institutional Service Shares. Because these
Shares pay marketing fees on an ongoing basis, your investment cost may be
higher over time than other shares with different sales charges and marketing
fees.


HOW TO PURCHASE SHARES

You may purchase Shares through an investment professional or directly from the
Fund. The Fund reserves the right to reject any request to purchase Shares.


THROUGH AN INVESTMENT PROFESSIONAL
o        Establish an account with the investment professional; and

o  Submit your purchase order to the investment professional before 2:00

   professional forwards the order to the Fund and the Fund receives payment by
   2:00 (Eastern time). You will become the owner of Shares and receive
   dividends when the Fund receives your payment.

Investment professionals should send payments according to the instructions in
the sections "By Wire" or "By Check."

     Form; and

o        Send your payment to the Fund by Federal Reserve wire or check.

You will become the owner of Shares after the Fund receives your wire or your
check. If your check does not clear, your purchase will be canceled and you

and will become a shareholder after the Fund receives the order.

Fund's portfolio securities.


LIMITATIONS ON REDEMPTION PROCEEDS
Redemption proceeds normally are wired or mailed within one business day after
receiving a request in proper form. Payment may be delayed up to seven days:

o        to allow your purchase to clear;

o        during periods of market volatility; or

o when a shareholder's trade activity or amount adversely impacts the Fund's
ability to manage its assets.

You will not accrue interest or dividends on uncashed checks from the Fund if
those checks are undeliverable and returned to the Fund.


ADDITIONAL CONDITIONS

Telephone Transactions
The Fund will record your telephone instructions. If the Fund does not follow
reasonable procedures, it may be liable for losses due to unauthorized or
fraudulent telephone instructions.


Share Certificates
The Fund no longer issues share certificates. If you are redeeming Shares
represented by certificates previously issued by the Fund, you must return the
certificates with your written redemption request. For your protection, send
your certificates by registered or certified mail, but do not endorse them.

ACCOUNT AND SHARE INFORMATION


Account Activity
You will receive periodic statements reporting all account activity, including
dividends and capital gains paid.


DIVIDENDS AND CAPITAL GAINS
The Fund declares any dividends daily and pays them monthly to shareholders. If
you purchase Shares by wire, you begin earning dividends on the day your wire is
received. If you purchase Shares by check, you begin earning dividends on the
business day after the Fund receives your check. In either case, you earn
dividends through the day your redemption request is received.

The Fund does not expect to realize any capital gains or losses. If capital
gains or losses were to occur, they could result in an increase or decrease in
dividends. The Fund pays any capital gains at least annually. Your dividends and
capital gains distributions will be automatically reinvested in additional
Shares without a sales charge, unless you elect cash payments.


ACCOUNTS WITH LOW BALANCES
Due to the high cost of maintaining accounts with low balances, accounts may be
closed if redemptions cause the account balance to fall below the minimum
initial investment amount. Before an account is closed, you will be notified and
allowed 30 days to purchase additional Shares to meet the minimum.


TAX INFORMATION
The Fund sends an annual statement of your account activity to assist you in
completing your federal, state and local tax returns. Fund distributions of
dividends and capital gains are taxable to you whether paid in cash or
reinvested in the Fund. Dividends are taxable as ordinary income; capital gains
are taxable at different rates depending upon the length of time the Fund holds
its assets.

Fund distributions are expected to be primarily dividends. Redemptions are
taxable sales. Please consult your tax adviser regarding your federal, state,
and local tax liability.


WHO MANAGES THE FUND?

The Board of Trustees governs the Fund. The Board selects and oversees the
Adviser, Federated Investment Management Company. The Adviser manages the Fund's
assets, including buying and selling portfolio securities. The Adviser's address
is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 175 mutual
funds and separate accounts, which total approximately $111 billion in assets as
of December 31, 1998. Federated was established in 1955 and is one of the
largest mutual fund investment managers in the United States with approximately
1,900 employees. More than 4,000 investment professionals make Federated Funds
available to their customers.


Advisory Fees
The Adviser receives an annual investment advisory fee of 0.40% of the Fund's
average daily net assets. The Adviser may voluntarily waive a portion of its fee
or reimburse the Fund for certain operating expenses.


Year 2000 Readiness
The "Year 2000" problem is the potential for computer errors or failures because
certain computer systems may be unable to interpret dates after December 31,
1999 or experience other date-related problems. The Year 2000 problem may cause
systems to process information incorrectly and could disrupt businesses, such as
the Fund, that rely on computers.

While it is impossible to determine in advance all of the risks to the Fund, the
Fund could experience interruptions in basic financial and operational
functions. Fund shareholders could experience errors or disruptions in Fund
share transactions or Fund communications.

The Fund's service providers are making changes to their computer systems to fix
any Year 2000 problems. In addition, they are working to gather information from
third-party providers to determine their Year 2000 readiness.

Year 2000 problems would also increase the risks of the Fund's investments. To
assess the potential effect of the Year 2000 problem, the Adviser is reviewing
information regarding the Year 2000 readiness of issuers of securities the Fund
may purchase. The financial impact of these issues for the Fund is still being
determined. There can be no assurance that potential Year 2000 problems would
not have a material adverse effect on the Fund.

HOW IS THE FUND ORGANIZED?

The Fund is a diversified portfolio of Money Market Obligations Trust (Trust).
The Trust is an open-end, management investment company that was established
under the laws of the Commonwealth of Massachusetts on October 3, 1988. The
Trust may offer separate series of shares representing interests in separate
portfolios of securities. The Fund, which was established on December 7, 1989,
was reorganized as a portfolio of the Trust on July ____ 1999. The Fund's
investment adviser is Federated Investment Management Company.


SECURITIES IN WHICH THE FUND INVESTS

In pursuing its investment strategy, the Fund may invest in the following
securities for any purpose that is consistent with its investment objective.


SECURITIES DESCRIPTIONS AND TECHNIQUES
Fixed Income Securities

Fixed income securities pay interest, dividends or distributions at a specified
rate. The rate may be a fixed percentage of the principal or adjusted
periodically. In addition, the issuer of a fixed income security must repay the
principal amount of the security, normally within a specified time. Fixed income
securities provide more regular income than equity securities. However, the
returns on fixed income securities are limited and normally do not increase with
the issuer's earnings. This limits the potential appreciation of fixed income
securities as compared to equity securities.

A security's yield measures the annual income earned on a security as a
percentage of its price. A security's yield will increase or decrease depending
upon whether it costs less (a discount) or more (a premium) than the principal
amount. If the issuer may redeem the security before its scheduled maturity, the
price and yield on a discount or premium security may change based upon the
probability of an early redemption. Securities with higher risks generally have
higher yields.

The following describes the types of fixed income securities in which the Fund
invests.

     Treasury Securities
     Treasury securities are direct obligations of the federal government of the
     United States. Treasury securities are generally regarded as having the
     lowest credit risks. Zero Coupon Securities Zero coupon securities do not
     pay interest or principal until final maturity unlike debt securities that
     provide periodic payments of interest (referred to as a coupon payment).
     Investors buy zero coupon securities at a price below the amount payable at
     maturity. The difference between the purchase price and the amount paid at
     maturity represents interest on the zero coupon security. Investors must
     wait until maturity to receive interest and principal, which increases the
     interest rate risks and credit risks of a zero coupon security. There are
     many forms of zero coupon securities. Some are issued at a discount and are
     referred to as zero coupon or capital appreciation bonds. Others are
     created from interest bearing bonds by separating the right to receive the
     bond's coupon payments from the right to receive the bond's principal due
     at maturity, a process known as coupon stripping. In addition, some
     securities give the issuer the option to deliver additional securities in
     place of cash interest payments, thereby increasing the amount payable at
     maturity. These are referred to as pay-in-kind or PIK securities.


<PAGE>


Special Transactions
     Delayed Delivery Transactions
     Delayed delivery transactions, including when issued transactions, are
     arrangements in which the Fund buys securities for a set price, with
     payment and delivery of the securities scheduled for a future time. During
     the period between purchase and settlement, no payment is made by the Fund
     to the issuer and no interest accrues to the Fund. The Fund records the
     transaction when it agrees to buy the securities and reflects their value
     in determining the price of its shares. Settlement dates may be a month or
     more after entering into these transactions so that the market values of
     the securities bought may vary from the purchase prices. Therefore, delayed
     delivery transactions create interest rate risks for the Fund. Delayed
     delivery transactions also involve credit risks in the event of a
     counterparty default. Asset Coverage In order to secure its obligations in
     connection with special transactions, the Fund will either own the
     underlying assets, enter into an offsetting transaction or set aside
     readily marketable securities with a value that equals or exceeds the
     Fund's obligations. Unless the Fund has other readily marketable assets to
     set aside, it cannot trade assets used to secure such obligations without
     terminating a special transaction. This may cause the Fund to miss
     favorable trading opportunities or to realize losses on special
     transactions.

INVESTMENT RISKS

There are many factors which may affect an investment in the Fund. The Fund's
principal risks are described in its prospectus. Additional risk factors are
outlined below.


Credit Risk
Credit risk is the possibility that an issuer will default on a security by
failing to pay interest or principal when due. If an issuer defaults, the Fund
will lose money. Credit risk includes the possibility that a party to a
transaction involving the Fund will fail to meet its obligations. This could
cause the Fund to lose the benefit of the transaction or prevent the Fund from
selling or buying other securities to implement its investment strategy.


INVESTMENT LIMITATIONS

Diversification

With respect to securities comprising 75% of the value of its total assets, the
Fund will not purchase securities of any one issuer (other than cash; cash
items; securities issued or guaranteed by the government of the United States or
its agencies or instrumentalities and repurchase agreements collateralized by
such U.S. government securities; and securities of other investment companies)
if, as a result, more than 5% of the value of its total assets would be invested
in securities of that issuer, or the Fund would own more than 10% of the
outstanding voting securities of that issuer.

Concentration

The Fund will not make investments that will result in the concentration of its
investments in the securities of issuers primarily engaged in the same industry.
Government securities, municipal securities and bank instruments are not deemed
to constitute an industry.



<PAGE>


Issuing Senior Securities and Borrowing Money

The Fund may borrow money, directly or indirectly, and issue senior securities
to the maximum extent permitted under the 1940 Act.

Pledging Assets

The Fund will not mortgage, pledge, or hypothecate any assets except as
necessary 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 pledge.

Lending Cash or Securities

The Fund will not lend any of its assets, except that it may purchase or hold
U.S. Treasury obligations as permitted by its investment objective, policies and
limitations or Declaration of Trust.

Investing in Real Estate

The Fund may not purchase or sell real estate, provided that this restriction
does not prevent the Fund from investing in issuers which invest, deal, or
otherwise engage in transactions in real estate or interests therein, or
investing in securities that are secured by real estate or interests therein.
The Fund may exercise its rights under agreements relating to such securities,
including the right to enforce security interests and to hold real estate
acquired by reason of such enforcement until that real estate can be liquidated
in an orderly manner.

Underwriting Securities

The Fund may not underwrite the securities of other issuers, except that the
Fund may engage in transactions involving the acquisition, disposition or resale
of its portfolio securities, under circumstances where it may be considered to
be an underwriter under the Securities Act of 1933.

Investing in Commodities

The Fund may not purchase or sell physical commodities, provided that the Fund
may purchase securities of companies that deal in commodities.

The above limitations cannot be changed unless authorized by the "vote of a
majority of its outstanding voting securities," as defined by the Investment
Company Act. The following limitations, however, may be changed by the Board
without shareholder approval. Shareholders will be notified before any material
change in these limitations becomes effective.

Buying on Margin

The Fund will not purchase securities on margin, provided that the Fund may
obtain short-term credits necessary for the clearance of purchases and sales of
securities.

Investing in Illiquid Securities

The Fund will not purchase securities for which there is no readily available
market, or enter into repurchase agreements or purchase time deposits maturing
in more than seven days, if immediately after and as a result, the value of such
securities would exceed, in the aggregate, 10% of the Fund's net assets.

Investing in Securities of Other Investment Companies

The Fund will not acquire securities of other investment companies, except as
part of a merger, consolidation, or other acquisition.

For purposes of the above limitations, the Fund considers certificates of
deposit and demand and time deposits issued by a U.S. branch of a domestic bank
or savings association having capital, surplus, and undivided profits in excess
of $100,000,000 at the time of investment to be "cash items." Except with
respect to borrowing money, if a percentage limitation is adhered to at the time
of 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 limitation.

For purposes of the above policy concerning concentration, in conformity with an
SEC position, the Fund considers "bank instruments" to be limited to instruments
of domestic banks.



<PAGE>


Regulatory Compliance

The Fund may follow non-fundamental operational policies that are more
restrictive than its fundamental investment limitations, as set forth in each
prospectus and this Statement of Additional Information, in order to comply with
applicable laws and regulations, including the provisions of and regulations
under the Investment Company Act of 1940. In particular, the Fund will comply
with the various requirements of Rule 2a-7 (the "Rule"), which regulates money
market mutual funds. The Fund will determine the effective maturity of its
investments according to the Rule. The Fund may change these operational
policies to reflect changes in the laws and regulations without the approval of
its shareholders.


DETERMINING MARKET VALUE OF SECURITIES

The Trustees have decided that the best method for determining the value of
portfolio instruments is amortized cost. Under this method, portfolio
instruments are valued at the acquisition cost as adjusted for amortization of
premium or accumulation of discount rather than at current market value.
Accordingly, neither the amount of daily income nor the net asset value is
affected by any unrealized appreciation or depreciation of the portfolio. In
periods of declining interest rates, the indicated daily yield on shares of the
Fund computed by dividing the annualized daily income on the Fund's portfolio by
the net asset value computed as above may tend to be higher than a similar
computation made by using a method of valuation based upon market prices and
estimates. In periods of rising interest rates, the opposite may be true.

The Fund's use of the amortized cost method of valuing portfolio instruments
depends on its compliance with certain conditions in the Rule. Under the Rule,
the Trustees must establish procedures reasonably designed to stabilize the net
asset value per share, as computed for purposes of distribution and redemption,
at $1.00 per share, taking into account current market conditions and the Fund's
investment objective. The procedures include monitoring the relationship between
the amortized cost value per share and the net asset value per share based upon
available indications of market value. The Trustees will decide what, if any,
steps should be taken if there is a difference of more than 0.5 of 1% between
the two values. The Trustees will take any steps they consider appropriate (such
as redemption in kind or shortening the average portfolio maturity) to minimize
any material dilution or other unfair results arising from differences between
the two methods of determining net asset value.




WHAT DO SHARES COST?

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.


HOW IS THE FUND SOLD?

Under the  Distributor's  Contract  with the Fund,  the  Distributor  (Federated
Securities Corp.) offers Shares on a continuous, best-efforts basis.


RULE 12B-1 PLAN
As a compensation-type plan, the Rule 12b-1 Plan is designed to pay the
Distributor (who may then pay investment professionals such as banks,
broker/dealers, trust departments of banks, and registered investment advisers)
for marketing activities (such as advertising, printing and distributing
prospectuses, and providing incentives to investment professionals) to promote
sales of Shares so that overall Fund assets are maintained or increased. This
helps the Fund achieve economies of scale, reduce per share expenses, and
provide cash for orderly portfolio management and Share redemptions. In
addition, the Fund's service providers that receive asset-based fees also
benefit from stable or increasing Fund assets.

The Fund may compensate the Distributor more or less than its actual marketing
expenses. In no event will the Fund pay for any expenses of the Distributor that
exceed the maximum Rule 12b-1 Plan fee.

For some classes of Shares, the maximum Rule 12b-1 Plan fee that can be paid in
any one year may not be sufficient to cover the marketing related expenses the
Distributor has incurred. Therefore, it may take the Distributor a number of
years to recoup these expenses.


SHAREHOLDER SERVICES
The Fund may pay Federated Shareholder Services Company, a subsidiary of
Federated Investors, Inc. (Federated), for providing shareholder services and
maintaining shareholder accounts. Federated Shareholder Services Company may
select others to perform these services for their customers and may pay them
fees.


SUPPLEMENTAL PAYMENTS
Investment professionals may be paid fees out of the assets of the Distributor
and/or Federated Shareholder Services Company (but not out of Fund assets). The
Distributor and/or Federated Shareholder Services Company may be reimbursed by
the Adviser or its affiliates.

Investment professionals receive such fees for providing distribution-related or
shareholder services such as sponsoring sales, providing sales literature,
conducting training seminars for employees, and engineering sales-related
computer software programs and systems. Also, investment professionals may be
paid cash or promotional incentives, such as reimbursement of certain expenses
relating to attendance at informational meetings about the Fund or other special
events at recreational-type facilities, or items of material value. These
payments will be based upon the amount of Shares the investment professional
sells or may sell and/or upon the type and nature of sales or marketing support
furnished by the investment professional.


SUBACCOUNTING SERVICES

Certain investment professionals may wish to use the transfer agent's
subaccounting system to minimize their internal recordkeeping requirements. The
transfer agent may charge a fee based on the level of subaccounting services
rendered. Investment professionals holding Shares in a fiduciary, agency,
custodial, or similar capacity may charge or pass through subaccounting fees as
part of or in addition to normal trust or agency account fees. They may also
charge fees for other services that may be related to the ownership of Shares.
This information should, therefore, be read together with any agreement between
the customer and the investment professional about the services provided, the
fees charged for those services, and any restrictions and limitations imposed.


REDEMPTION IN KIND

Although the Fund intends to pay Share redemptions in cash, it reserves the
right, as described below, to pay the redemption price in whole or in part by a
distribution of the Fund's portfolio securities.

Because the Fund has elected to be governed by Rule 18f-1 under the Investment
Company Act of 1940, the Fund is obligated to pay Share redemptions to any one
shareholder in cash only up to the lesser of $250,000 or 1% of the net assets
represented by such Share class during any 90-day period.

Any Share redemption payment greater than this amount will also be in cash
unless the Fund's Board determines that payment should be in kind. In such a
case, the Fund will pay all or a portion of the remainder of the redemption in
portfolio securities, valued in the same way as the Fund determines its NAV. The
portfolio securities will be selected in a manner that the Fund's Board deems
fair and equitable and, to the extent available, such securities will be readily
marketable.

Redemption in kind is not as liquid as a cash redemption. If redemption is made
in kind, shareholders receiving the portfolio securities and selling them before
their maturity could receive less than the redemption value of the securities
and could incur certain transaction costs.


MASSACHUSETTS PARTNERSHIP LAW

Under certain circumstances, shareholders may be held personally liable as
partners under Massachusetts law for obligations of the Trust. To protect its
shareholders, the Trust has filed legal documents with Massachusetts that
expressly disclaim the liability of its shareholders for acts or obligations of
the Trust.

In the unlikely event a shareholder is held personally liable for the Trust's
obligations, the Trust is required by the Declaration of Trust to use its
property to protect or compensate the shareholder. On request, the Trust will
defend any claim made and pay any judgment against a shareholder for any act or
obligation of the Trust. Therefore, financial loss resulting from liability as a
shareholder will occur only if the Trust itself cannot meet its obligations to
indemnify shareholders and pay judgments against them.


ACCOUNT AND SHARE INFORMATION


VOTING RIGHTS
Each share of the Fund gives the shareholder one vote in Trustee elections and
other matters submitted to shareholders for vote.

 All Shares of the Trust have equal voting rights, except that in matters
affecting only a particular Fund or class, only Shares of that Fund or class are
entitled to vote.

Trustees may be removed by the Board or by shareholders at a special meeting. A
special meeting of shareholders will be called by the Board upon the written
request of shareholders who own at least 10% of the Trust's outstanding shares
of all series entitled to vote.

As of ___________, the following shareholders owned of record, beneficially, or
both, 5% or more of outstanding Shares:


TAX INFORMATION


FEDERAL INCOME TAX
The Fund intends to meet requirements of Subchapter M of the Internal Revenue
Code applicable to regulated investment companies. If these requirements are not
met, it will not receive special tax treatment and will pay federal income tax.

The Fund will be treated as a single, separate entity for federal income tax
purposes so that income earned and capital gains and losses realized by the
Trust's other portfolios will be separate from those realized by the Fund.


WHO MANAGES AND PROVIDES SERVICES TO THE FUND?


BOARD OF TRUSTEES
The Board is responsible for managing the Trust's business affairs and for
exercising all the Trust's powers except those reserved for the shareholders.

Fund Complex for the most recent calendar year. The Trust is comprised of
fifteen Funds and The Federated Fund Complex is comprised of 56 investment
companies, whose investment advisers are affiliated with the Trust's Adviser.

As of ___________, 1999, the Fund's Board and Officers as a group owned less
than 1% of the Fund's outstanding shares.

An asterisk (*) denotes a Trustee who is deemed to be an interested person as
defined in the Investment Company Act of 1940. The following symbol (#) denotes

INVESTMENT ADVISER
The Adviser conducts investment research and makes investment decisions for the
Fund.

The Adviser is a wholly owned subsidiary of Federated.

The Adviser shall not be liable to the Trust or any Fund 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 Trust.


Other Related Services
Affiliates of the Adviser may, from time to time, provide certain electronic
equipment and software to institutional customers in order to facilitate the
purchase of Fund Shares offered by the Distributor.


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. 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. In selecting among firms believed to meet these
criteria, the Adviser may give consideration to those firms which have sold or
are selling Shares of the Fund and other funds distributed by the Distributor

selects brokers and dealers subject to review by the Fund's Board.

accounts managed by the Adviser. When the Fund and one or more of those accounts
invests in, or disposes of, the same security, available investments or
opportunities for sales will be allocated among the Fund and the account(s) in a
manner believed by the Adviser to be equitable. While the coordination and
ability to participate in volume transactions may benefit the Fund, it is
possible that this procedure could adversely impact the price paid or received
and/or the position obtained or disposed of by the Fund.

HOW DOES THE FUND MEASURE PERFORMANCE?

The Fund may advertise Share performance by using the Securities and Exchange
Commission's (SEC) standard method for calculating performance applicable to all
mutual funds. The SEC also permits this standard performance information to be
accompanied by non-standard performance information.

Unless otherwise stated, any quoted Share performance reflects the effect of
non-recurring charges, such as maximum sales charges, which, if excluded, would
increase the total return and yield. The performance of Shares depends upon such
variables as: portfolio quality; average portfolio maturity; type and value of
portfolio securities; changes in interest rates; changes or differences in the
Fund's or any class of Shares' expenses; and various other factors.

Share performance fluctuates on a daily basis largely because net earnings
fluctuate daily. Both net earnings and offering price per Share are factors in
the computation of yield and total return.

TOTAL RETURN
Total return represents the change (expressed as a percentage) in the value of
Shares over a specific period of time, and includes the investment of income and
capital gains distributions.

The average annual total return for Shares 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 NAV 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 the annual reinvestment of all
dividends and distributions.


YIELD
The yield of Shares is based upon the seven days ending on the day of the
calculation, called the "base period." This yield is calculated by: determining
the net change in the value of a hypothetical account with a balance of one
Share at the beginning of the base period, with the net change excluding capital
changes but including the value of any additional Shares purchased with
dividends earned from the original one Share and all dividends declared on the
original and any purchased Shares; dividing the net change in the account's
value by the value of the account at the beginning of the base period to
determine the base period return; and multiplying the base period return by
365/7. The effective yield is calculated by compounding the unannualized
base-period return by: adding one to the base-period return, raising the sum to
the 365/7th power; and subtracting one from the result.

To the extent investment professionals and broker/dealers charge fees in
connection with services provided in conjunction with an investment in Shares,
the Share performance is lower for shareholders paying those fees.




PERFORMANCE COMPARISONS
Advertising and sales literature may include:

o    references  to  ratings,   rankings,   and  financial  publications  and/or
     performance comparisons of Shares to certain indices;

o  charts, graphs and illustrations using the Fund's returns, or returns in
   general, that demonstrate investment concepts such as tax-deferred
   compounding, dollar-cost averaging and systematic investment;

o  discussions of economic, financial and political developments and their
   impact on the securities market, including the portfolio manager's views on
   how such developments could impact the Funds; and

o information about the mutual fund industry from sources such as the Investment
Company Institute.

The Fund may compare its performance, or performance for the types of securities
in which it invests, to a variety of other investments, including federally
insured bank products such as bank savings accounts, certificates of deposit,
and Treasury bills.

The Fund may quote information from reliable sources regarding individual
countries and regions, world stock exchanges, and economic and demographic
statistics.

You may use financial publications and/or indices to obtain a more complete view
of Share performance. When comparing performance, you should consider all
relevant factors such as the composition of the 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:

oLipper Analytical  Services,  Inc. ranks funds in various fund categories based
     on total return, which assumes the reinvestment of all income dividends and
     capital gains distributions, if any.

oIBC/Donoghue's Money Fund Report publishes annualized yields of money market
funds weekly. Donoghue's Money Market Insight publication reports monthly and
12-month-to-date investment results for the same money funds.

oMoney, a monthly magazine, regularly ranks money market funds in various
categories based on the latest available seven-day effective yield.

oSalomon 30-Day Treasury Bill Index is a weekly quote of the most representative
yields for selected securities, issued by the U.S. Treasury, maturing in 30
days.

Example
This Example is intended to help you compare the cost of investing in the Fund's
Class A Shares and Class B Shares with the cost of investing in other mutual
funds.
  The Example assumes that you invest $10,000 in the Fund's Class A Shares and
Class B Shares for the time periods indicated and then redeem all of your Shares
at the end of those periods. Expenses assuming no redemption are also shown for
Class B Shares. The Example also assumes that your investment has a 5% return
each year and that the Fund's Class A Shares and Class B Shares operating
expenses are before waivers as estimated in the table and remain the same.
Although your actual costs may be higher or lower, based on these assumptions
your costs would be: Share Class 1 Year 3 Years 5 Years 10 Years Class A Shares
Expenses assuming redemption $120 $375 $649 $1,432 Class B Shares Expenses
assuming redemption $763 $1,044 $1,274 $2,254 Expenses assuming no redemption

WHAT ARE THE FUND'S INVESTMENT STRATEGIES?
The Fund invests primarily in a portfolio of U.S. Treasury and government agency
securities with a maturity of 397 days or less. The dollar-weighted average
maturity of the Fund's portfolio will be 90 days or less.

The adviser targets a dollar-weighted average portfolio maturity range based
upon its interest rate outlook. The adviser formulates its interest rate outlook
by analyzing a variety of factors, such as:

o current U.S. economic activity and the economic outlook ;

o current short-term interest rates;

o the Federal Reserve Board's policies regarding short-term interest rates; and

o    the  potential  effects of foreign  economic  activity  on U.S.  short-term
     interest rates.

The adviser generally shortens the portfolio's dollar-weighted average maturity
when it expects interest rates to rise and extends the maturity when it expects
interest rates to fall. The adviser selects securities used to lengthen or
shorten the portfolio's dollar-weighted average maturity by comparing the
returns currently offered by different investments to their historical and
expected returns.


WHAT ARE THE PRINCIPAL SECURITIES IN WHICH THE FUND INVESTS?
Fixed Income Securities

Fixed income securities pay interest, dividends or distributions at a specified
rate. The rate may be a fixed percentage of the principal or adjusted
periodically. In addition, the issuer of a fixed income security must repay the
principal amount of the security, normally within a specified time. The Fund
invests in the following types of fixed income securities.

     Treasury securities

     Treasury securities are direct obligations of the federal government of the
United States.

     Agency securities

     Agency securities are issued or guaranteed by a federal agency or other
     government sponsored entity acting under federal authority (a GSE). The
     United States supports some GSEs with its full faith and credit. Other GSEs
     receive support through federal subsidies, loans or other benefits. A few
     GSEs have no explicit financial support, but are regarded as having implied
     support because the federal government sponsors their activities.

     Bank Instruments
     Bank instruments are securities of banks and savings associations the
     principal amount of which is fully insured by the FDIC or FSLIC.
Repurchase Agreements

Repurchase agreements are transactions in which the Fund buys a security from a
dealer or bank and agrees to sell the security back at a mutually agreed upon
time and price. The repurchase price exceeds the sale price, reflecting the
Fund's return on the transaction. This return is unrelated to the interest rate
on the underlying security. The Fund will enter into repurchase agreements only
with banks and other recognized financial institutions, such as securities
dealers, deemed creditworthy by the Adviser. Repurchase agreements are subject
to credit risks.



<PAGE>


Delayed Delivery Transactions

Delayed delivery transactions, including when issued transactions, are
arrangements in which the Fund buys securities for a set price, with payment and
delivery of the securities scheduled for a future time. During the period
between purchase and settlement, no payment is made by the Fund to the issuer
and no interest accrues to the Fund. The Fund records the transaction when it
agrees to buy the securities and reflects their value in determining the price
of its shares. Settlement dates may be a month or more after entering into these
transactions so that the market values of the securities bought may vary from
the purchase prices. Therefore, delayed delivery transactions create interest
rate risks for the Fund. Delayed delivery transactions also involve credit risks
in the event of a counterparty default.

Investing in Securities of Other Investment Companies
The Fund may invest its assets in securities of other investment companies,
including the securities of affiliated money market funds, as an efficient means
of carrying out its investment policies and managing its uninvested cash.

WHAT ARE THE SPECIFIC RISKS OF INVESTING IN THE FUND?
Although there are many factors that may affect an investment in the Fund, the
principal risks of investing in a U.S. government money market fund are
described below.

Interest Rate Risk

Prices of fixed income securities rise and fall in response to changes in the
interest rate paid by similar securities. Generally, when interest rates rise,
prices of fixed income securities fall. However, market factors, such as demand
for particular fixed income securities, may cause the price of certain fixed
income securities to fall while the prices of other securities rise or remain
unchanged.

Interest rate changes have a greater effect on the price of fixed income
securities with longer maturities. Money market funds try to minimize this risk
by purchasing short-term securities.

Credit Risk

Credit risk includes the possibility that a party to a transaction involving the
Fund will fail to meet its obligations. This could cause the Fund to lose the
benefit of the transaction or prevent the Fund from selling or buying other
securities to implement its investment strategy.


WHAT DO SHARES COST?

You can purchase, redeem or exchange Shares any day the New York Stock Exchange
(NYSE) is open. The Fund attempts to stabilize the net asset value (NAV) of its
Shares at $1.00 by valuing the portfolio securities using the amortized cost
method. The Fund cannot guarantee that its NAV will always remain at $1.00 per
Share. The Fund does not charge a front-end sales charge. NAV is determined at
12:00 noon and 3:00 p.m. (Eastern time) and as of the end of regular trading
(normally 4:00 p.m. Eastern time) each day the NYSE is open.

The required minimum initial investment for Fund Shares is $1,500. However, the
minimum investment for a retirement account in any class is $250. Subsequent
investments must be in amounts of at least $100.

An account may be opened with a smaller amount as long as the $1,500 minimum,
and, in the case of retirement accounts, the $250 minimum, is reached within 90
days. An institutional investor's minimum investment is calculated by combining
all accounts it maintains with the Fund. Accounts established through investment
professionals may be subject to a smaller minimum investment amount. Keep in
mind that investment professionals may charge you fees for their services in
connection with your Share transactions.




<PAGE>



SALES CHARGE WHEN YOU REDEEM
Your redemption proceeds may be reduced by a sales charge, commonly referred to
as a contingent deferred sales charge (CDSC).

Class B Shares
Shares Held Up To:                                  CDSC
1 year                                                 5.50%
2 years                                                4.75%
3 years                                                4.00%
4 years                                                3.00%
5 years                                                2.00%
6 years                                                1.00%
7 years or more                                        0.00%

You will not be charged a CDSC when redeeming Shares:

o        purchased with reinvested dividends or capital gains;

o    purchased within 120 days of redeeming Shares of an equal or lesser amount;

o  that you exchanged into the same share class of another Federated Fund where
   the shares were held for the applicable CDSC holding period (other than a
   money market fund);

o    purchased  through  investment  professionals  who did not receive advanced
     sales payments; or

o    if, after you purchase Shares, you become disabled as defined by the IRS.

In addition, you will not be charged a CDSC:

     o    if the Fund  redeems  your  Shares and  closes  your  account  for not
          meeting the minimum balance requirement;

o        if your redemption is a required retirement plan distribution;

o        upon the death of the last surviving shareholder of the account.

If your redemption qualifies, you or your investment professional should notify
the Distributor at the time of redemption to eliminate the CDSC. If the
Distributor is not notified, the CDSC will apply.

To keep the sales charge as low as possible, the Fund redeems your Shares in
this order:

o        Shares that are not subject to a CDSC; and

o  Shares held the longest (to determine the number of years your Shares have
   been held, include the time you held shares of other Federated Funds that
   have been exchanged for Shares of this Fund); and

The CDSC is then calculated using the share price at the time of purchase or
redemption, whichever is lower.


HOW IS THE FUND SOLD?

The Fund offers two share classes: Class A Shares and Class B Shares, each
representing interests in a single portfolio of securities.

The Fund's Distributor markets the Shares described in this prospectus to
institutions or individuals, directly or through investment professionals.

When the Distributor receives marketing fees, it may pay some or all of them to
investment professionals. The Distributor and its affiliates may pay out of
their assets other amounts (including items of material value) to investment
professionals for marketing and servicing Shares. The Distributor is a
subsidiary of Federated Investors, Inc. (Federated).


RULE 12B-1 PLAN
The Fund has adopted a Rule 12b-1 Plan, which allows it to pay marketing fees to
the Distributor and investment professionals for the sale, distribution and
customer servicing of the Fund's Class B Shares. Because Class B Shares pay
marketing fees on an ongoing basis, your investment cost may be higher over time
than other shares with different sales charges and marketing fees.


HOW TO PURCHASE SHARES

You may purchase Shares through an investment professional, directly from the
Fund, or through an exchange from another Federated Fund. The Fund reserves the
right to reject any request to purchase or exchange Shares. Where the Fund
offers more than one share class and you do not specify the class choice on your
New Account Form or form of payment (e.g., Federal Reserve wire or check) you
automatically will receive Class A Shares.


THROUGH AN INVESTMENT PROFESSIONAL
o        Establish an account with the investment professional; and

o  Submit your purchase order to the investment professional before 3:00 p.m.
   (Eastern time). You will receive that day's dividend if the investment
   professional forwards the order to the Fund and the Fund receives payment by
   3:00 p.m. (Eastern time). You will become the owner of Shares and receive
   dividends when the Fund receives your payment.

Investment professionals should send payments according to the instructions in
the sections "By Wire" or "By Check."


DIRECTLY FROM THE FUND

     o    Establish  your  account with the Fund by  submitting a completed  New
          Account Form; and

o        Send your payment to the Fund by Federal Reserve wire or check.

You will become the owner of Shares after the Fund receives your wire or your
check. If your check does not clear, your purchase will be canceled and you
could be liable for any losses or fees the Fund or its transfer agent incurs.

An institution may establish an account and place an order by calling the Fund
and will become a shareholder after the Fund receives the order.


By Wire Send your wire to:

   State Street Bank and Trust Company
   Boston, MA
   Dollar Amount of Wire
   ABA Number 011000028
   Attention: EDGEWIRE
   Wire Order Number, Dealer Number, or Group Number
   Nominee/Institution Name
   Fund Name and Number and Account Number
You cannot purchase Shares by wire on holidays when wire transfers are
restricted.

Payment should be made in U.S. dollars and drawn on a U.S. bank. The Fund will
not accept third-party checks (checks originally payable to someone other than

by check is converted into federal funds (normally the business day after the
check is received) and Shares begin earning dividends the next day.


THROUGH AN EXCHANGE
You may purchase Shares through an exchange from the same Share class of another
Federated Fund. You must meet the minimum initial investment requirement for
purchasing Shares and both accounts must have identical registrations.


BY SYSTEMATIC INVESTMENT PROGRAM
Once you have opened an account, you may automatically purchase additional
Shares on a regular basis by completing the Systematic Investment Program (SIP)
section of the New Account Form or by contacting the Fund or your investment
professional. The minimum investment amount for SIPs is $50.


BY AUTOMATED CLEARING HOUSE (ACH)
Once you have opened an account, you may purchase additional Shares through a
depository institution that is an ACH member. This purchase option can be
established by completing the appropriate sections of the New Account Form.


RETIREMENT INVESTMENTS
You may purchase Shares as retirement investments (such as qualified plans and
IRAs or transfer or rollover of assets). Call your investment professional or
the Fund for information on retirement investments. We suggest that you discuss
retirement investments with your tax adviser. You may be subject to an annual
IRA account fee.


HOW TO REDEEM AND EXCHANGE SHARES

You should redeem or exchange Shares:

     o    through an investment  professional if you purchased Shares through an
          investment professional; or

o        directly from the Fund if you purchased Shares directly from the Fund.


THROUGH AN INVESTMENT PROFESSIONAL
Submit your redemption or exchange request to your investment professional by
the end of regular trading on the NYSE (normally 4:00 p.m. Eastern time).
Investment professionals are responsible for promptly submitting redemption
requests and providing proper written redemption instructions as outlined below.




<PAGE>



DIRECTLY FROM THE FUND

By Telephone
You may redeem or exchange Shares by calling the Fund once you have completed
the appropriate authorization form for telephone transactions.

If you call before 12:00 noon (Eastern time) your redemption will be wired to
you the same day. You will not receive that day's dividend.

If you call after 12:00 noon (Eastern time) your redemption will be wired to you
the following business day. You will receive that day's dividend. Under limited
circumstances, arrangements may be made with the Distributor for same-day
payment of redemption proceeds, without that day's dividend, for redemption
requests received before 2:00 p.m. (Eastern time).


By Mail
You may redeem or exchange Shares by mailing a written request to the Fund.

Your redemption request will be processed on the day the Fund receives your
written request in proper form. Dividends are paid up to and including the day
that a redemption request is processed.

Send requests by mail to:

   Federated Shareholder Services Company
   P.O. Box 8600
   Boston, MA 02266-8600
Send requests by private courier or overnight delivery service to:

   Federated Shareholder Services Company
   1099 Hingham Street
   Rockland, MA 02370-3317 All requests must include:

o        Fund Name and Share Class, account number and account registration;

o        amount to be redeemed or exchanged;

o        signatures of all Shareholders exactly as registered; and

o if exchanging, the Fund Name and Share Class, account number and account
registration into which you are exchanging.

Call your investment professional or the Fund if you need special instructions.


Signature Guarantees Signatures must be guaranteed if:

     o    your  redemption  will be sent to an address other than the address of
          record;

     o    your  redemption will be sent to an address of record that was changed
          within the last 30 days;

     o    a redemption  is payable to someone other than the  shareholder(s)  of
          record; or

o if exchanging (transferring) into another fund with a different shareholder
registration.

A signature guarantee is designed to protect your account from fraud. Obtain a
signature guarantee from a bank or trust company, savings association, credit
union or broker, dealer, or securities exchange member. A notary public cannot
provide a signature guarantee.


PAYMENT METHODS FOR REDEMPTIONS
Your redemption proceeds will be mailed by check to your address of record. The
following payment options are available if you complete the appropriate section
of the New Account Form or an Account Service Options Form. These payment
options require a signature guarantee if they were not established when the
account was opened:

     o    an electronic transfer to your account at a financial institution that
          is an ACH member; or

o wire payment to your account at a domestic commercial bank that is a Federal
Reserve System member.


Redemption in Kind
Although the Fund intends to pay Share redemptions in cash, it reserves the
right to pay the redemption price in whole or in part by a distribution of the
Fund's portfolio securities.


LIMITATIONS ON REDEMPTION PROCEEDS
Redemption proceeds normally are wired or mailed within one business day after
receiving a request in proper form. Payment may be delayed up to seven days:

o        to allow your purchase to clear;

o        during periods of market volatility; or

o when a shareholder's trade activity or amount adversely impacts the Fund's
ability to manage its assets.

You will not accrue interest or dividends on uncashed checks from the Fund if
those checks are undeliverable and returned to the Fund.


REDEMPTIONS FROM RETIREMENT ACCOUNTS
In the absence of your specific instructions, 10% of the value of your
redemption from a retirement account in the Fund may be withheld for taxes. This
withholding only applies to certain types of retirement accounts.


EXCHANGE PRIVILEGES
You may exchange Shares of the Fund into Shares of the same class of another
Federated Fund. To do this, you must:

o        ensure that the account registrations are identical;

o        meet any minimum initial investment requirements; and

o        receive a prospectus for the fund into which you wish to exchange.

An exchange is treated as a redemption and a subsequent purchase, and is a
taxable transaction.

The Fund may modify or terminate the exchange privilege at any time. The Fund's
management or investment adviser may determine from the amount, frequency and
pattern of exchanges that a shareholder is engaged in excessive trading that is
detrimental to the Fund and other shareholders. If this occurs, the Fund may
terminate the availability of exchanges to that shareholder and may bar that
shareholder from purchasing other Federated Funds.


SYSTEMATIC WITHDRAWAL/exchange PROGRAM
You may automatically redeem or exchange Shares in a minimum amount of $100 on a
regular basis. Complete the appropriate section of the New Account Form or an
Account Service Options Form or contact your investment professional or the
Fund. Your account value must meet the minimum initial investment amount at the
time the program is established. This program may reduce, and eventually
deplete, your account. Payments should not be considered yield or income.




<PAGE>



Systematic Withdrawal Program (SWP) On Class B Shares You will not be charged a
CDSC on SWP redemptions if:

o        you redeem 12% or less of your account value in a single year;

o        you reinvest all dividends and capital gains distributions; and

o  your account has at least a $10,000 balance when you establish the SWP. (You
   cannot aggregate multiple Class B Share accounts to meet this minimum
   balance).

You will be subject to a CDSC on redemption amounts that exceed the 12% annual
limit. In measuring the redemption percentage, your account is valued when you
establish the SWP and then annually at calendar year-end. You can redeem
monthly, quarterly, or semi-annually.

For SWP accounts established prior to April 1, 1999, your account must be at
least one year old in order to be eligible for the waiver of the CDSC.


CHECKWRITING  (Class A Shares only)
You may request checks to redeem your Class A Shares. Your account will continue
to receive the daily dividend declared on the Class A Shares being redeemed
until the check is presented for payment.


DEBIT CARD (Class A Shares only)
You may request a debit card account that allows you to redeem Class A Shares.
There is an annual fee for this service that the Fund will automatically deduct
from your account.


ADDITIONAL CONDITIONS

Telephone Transactions
The Fund will record your telephone instructions. If the Fund does not follow
reasonable procedures, it may be liable for losses due to unauthorized or
fraudulent telephone instructions.


Share Certificates
The Fund no longer issues share certificates. If you are redeeming or exchanging
Shares represented by certificates previously issued by the Fund, you must
return the certificates with your written redemption or exchange request. For
your protection, send your certificates by registered or certified mail, but do
not endorse them.


ACCOUNT AND SHARE INFORMATION


Account Activity
You will receive periodic statements reporting all account activity, including
systematic transactions, dividends and capital gains paid.


DIVIDENDS AND CAPITAL GAINS
The Fund declares any dividends daily and pays them monthly to shareholders. If
you purchase Shares by wire, you begin earning dividends on the day your wire is
received. If you purchase Shares by check, you begin earning dividends on the
business day after the Fund receives your check. In either case, you earn
dividends through the day your redemption request is received.

The Fund does not expect to realize any capital gains or losses. If capital
gains or losses were to occur, they could result in an increase or decrease in
dividends. The Fund pays any capital gains at least annually. Your dividends and
capital gains distributions will be automatically reinvested in additional
Shares without a sales charge, unless you elect cash payments.


ACCOUNTS WITH LOW BALANCES
Due to the high cost of maintaining accounts with low balances, non-retirement
accounts may be closed if redemptions or exchanges cause the account balance to
fall below the minimum initial investment amount. Before an account is closed,
you will be notified and allowed 30 days to purchase additional Shares to meet
the minimum.


TAX INFORMATION
The Fund sends an annual statement of your account activity to assist you in
completing your federal, state and local tax returns. Fund distributions of
dividends and capital gains are taxable to you whether paid in cash or
reinvested in the Fund. Dividends are taxable as ordinary income; capital gains
are taxable at different rates depending upon the length of time the Fund holds
its assets.

Fund distributions are expected to be primarily dividends. Redemptions and
exchanges are taxable sales. Please consult your tax adviser regarding your
federal, state, and local tax liability.


WHO MANAGES THE FUND?

The Board of Trustees governs the Fund. The Board selects and oversees the
Adviser, Federated Investment Management Company. The Adviser manages the Fund's
assets, including buying and selling portfolio securities. The Adviser's address
is Federated Investors Tower, 1001 Liberty Avenue, Pittsburgh, PA 15222-3779.

The Adviser and other subsidiaries of Federated advise approximately 175 mutual
funds and separate accounts, which total approximately $111 billion in assets as
of December 31, 1998. Federated was established in 1955 and is one of the
largest mutual fund investment managers in the United States with approximately
1,900 employees. More than 4,000 investment professionals make Federated Funds
available to their customers.


advisory fees
The Adviser receives an annual investment advisory fee based on the Fund's
average daily net assets as shown in the chart below. The Adviser may
voluntarily waive a portion of its fee or reimburse the Fund for certain
operating expenses.


                                    Fee as
Average Daily                      Percentage of
  Net Assets               Average Daily Net Assets
First $500 million                          0.500%

Second $500 million                 0.475%

Third $500 million                  0.450%

Fourth $500 million                 0.425%

Over $2 billion                     0.400%


Year 2000 Readiness
The "Year 2000" problem is the potential for computer errors or failures because
certain computer systems may be unable to interpret dates after December 31,
1999 or experience other date-related problems. The Year 2000 problem may cause
systems to process information incorrectly and could disrupt businesses, such as
the Fund, that rely on computers.

While it is impossible to determine in advance all of the risks to the Fund, the
Fund could experience interruptions in basic financial and operational
functions. Fund shareholders could experience errors or disruptions in Fund
share transactions or Fund communications.

The Fund's service providers are making changes to their computer systems to fix
any Year 2000 problems. In addition, they are working to gather information from
third-party providers to determine their Year 2000 readiness.

Year 2000 problems would also increase the risks of the Fund's investments. To
assess the potential effect of the Year 2000 problem, the Adviser is reviewing
information regarding the Year 2000 readiness of issuers of securities the Fund
may purchase.

The financial impact of these issues for the Fund is still being determined.
There can be no assurance that potential Year 2000 problems would not have a
material adverse effect on the Fund.

HOW IS THE FUND ORGANIZED?

The Fund is a diversified portfolio of Money Market Obligations Trust (Trust).
The Trust is an open-end, management investment company that was established
under the laws of the Commonwealth of Massachusetts on October 3, 1988. The
Trust may offer separate series of shares representing interests in separate
portfolios of securities. The Fund, which was established on August 30, 1979,
was reorganized as a portfolio of the Trust on July _____ 1999. The Fund's
investment adviser is Federated Investment Management Company.


SECURITIES IN WHICH THE FUND INVESTS

In pursuing its investment strategy, the Fund may invest in the following
securities for any purpose that is consistent with its investment objective.


SECURITIES DESCRIPTIONS AND TECHNIQUES
Fixed Income Securities
Fixed income securities pay interest, dividends or distributions at a specified
rate. The rate may be a fixed percentage of the principal or adjusted
periodically. In addition, the issuer of a fixed income security must repay the
principal amount of the security, normally within a specified time. Fixed income
securities provide more regular income than equity securities. However, the
returns on fixed income securities are limited and normally do not increase with
the issuer's earnings. This limits the potential appreciation of fixed income
securities as compared to equity securities. A security's yield measures the
annual income earned on a security as a percentage of its price. A security's
yield will increase or decrease depending upon whether it costs less (a
discount) or more (a premium) than the principal amount. If the issuer may
redeem the security before its scheduled maturity, the price and yield on a
discount or premium security may change based upon the probability of an early
redemption. Securities with higher risks generally have higher yields. The
following describes the types of fixed income securities in which the Fund
invests.
     Treasury Securities
     Treasury securities are direct obligations of the federal government of the
     United States. Treasury securities are generally regarded as having the
     lowest credit risks. Agency Securities Agency securities are issued or
     guaranteed by a federal agency or other government sponsored entity acting
     under federal authority (a GSE). The United States supports some GSEs with
     its full faith and credit. Other GSEs receive support through federal
     subsidies, loans or other benefits. A few GSEs have no explicit financial
     support, but are regarded as having implied support because the federal
     government sponsors their activities. Agency securities are generally
     regarded as having low credit risks, but not as low as treasury securities.
     Bank Instruments Bank instruments are securities of banks and savings
     associations the principal amount of which is fully insured by the FDIC or
     FSLIC.

Investing in Securities of Other Investment Companies
The Fund may invest its assets in securities of other investment companies,
including the securities of affiliated money market funds, as an efficient means
of carrying out its investment policies and managing its uninvested cash.

Special Transactions
     Repurchase Agreements
     Repurchase agreements are transactions in which the Fund buys a security
     from a dealer or bank and agrees to sell the security back at a mutually
     agreed upon time and price. The repurchase price exceeds the sale price,
     reflecting the Fund's return on the transaction. This return is unrelated
     to the interest rate on the underlying security. The Fund will enter into
     repurchase agreements only with banks and other recognized financial
     institutions, such as securities dealers, deemed creditworthy by the
     Adviser. The Fund's custodian or subcustodian will take possession of the
     securities subject to repurchase agreements. The Adviser or subcustodian
     will monitor the value of the underlying security each day to ensure that
     the value of the security always equals or exceeds the repurchase price.
     Repurchase agreements are subject to credit risks. Delayed Delivery
     Transactions Delayed delivery transactions, including when issued
     transactions, are arrangements in which the Fund buys securities for a set
     price, with payment and delivery of the securities scheduled for a future
     time. During the period between purchase and settlement, no payment is made
     by the Fund to the issuer and no interest accrues to the Fund. The Fund
     records the transaction when it agrees to buy the securities and reflects
     their value in determining the price of its shares. Settlement dates may be
     a month or more after entering into these transactions so that the market
     values of the securities bought may vary from the purchase prices.
     Therefore, delayed delivery transactions create interest rate risks for the
     Fund. Delayed delivery transactions also involve credit risks in the event
     of a counterparty default. Asset Coverage In order to secure its
     obligations in connection with special transactions, the Fund will either
     own the underlying assets, enter into an offsetting transaction or set
     aside readily marketable securities with a value that equals or exceeds the
     Fund's obligations. Unless the Fund has other readily marketable assets to
     set aside, it cannot trade assets used to secure such obligations without
     terminating a special transaction. This may cause the Fund to miss
     favorable trading opportunities or to realize losses on special
     transactions.

INVESTMENT RISKS
There are many factors which may affect an investment in the Fund. The Fund's
principal risks are described in its prospectus. Additional risk factors are
outlined below.

Credit Risk

Credit risk is the possibility that an issuer will default on a security by
failing to pay interest or principal when due. If an issuer defaults, the Fund
will lose money.


INVESTMENT LIMITATIONS

Diversification

With respect to securities comprising 75% of the value of its total assets, the
Fund will not purchase securities of any one issuer (other than cash; cash
items; securities issued or guaranteed by the government of the United States or
its agencies or instrumentalities and repurchase agreements collateralized by
such U.S. government securities; and securities of other investment companies)
if, as a result, more than 5% of the value of its total assets would be invested
in securities of that issuer, or the Fund would own more than 10% of the
outstanding voting securities of that issuer.

Concentration

The Fund will not make investments that will result in the concentration of its
investments in the securities of issuers primarily engaged in the same industry.
Government securities, municipal securities and bank instruments are not deemed
to constitute an industry.



<PAGE>


Issuing Senior Securities and Borrowing Money

The Fund may borrow money, directly or indirectly, and issue senior securities
to the maximum extent permitted under the 1940 Act.

Lending Cash or Securities

The Fund may not make loans, provided that this restriction does not prevent the
Fund from purchasing debt obligations, entering into repurchase agreements,
lending its assets to broker/dealers or institutional investors and investing in
loans, including assignments and participation interests.

Investing in Real Estate

The Fund may not purchase or sell real estate, provided that this restriction
does not prevent the Fund from investing in issuers which invest, deal, or
otherwise engage in transactions in real estate or interests therein, or
investing in securities that are secured by real estate or interests therein.
The Fund may exercise its rights under agreements relating to such securities,
including the right to enforce security interests and to hold real estate
acquired by reason of such enforcement until that real estate can be liquidated
in an orderly manner.

Investing in Commodities

The Fund may not purchase or sell physical commodities, provided that the Fund
may purchase securities of companies that deal in commodities.

Underwriting Securities

The Fund may not underwrite the securities of other issuers, except that the
Fund may engage in transactions involving the acquisition, disposition or resale
of its portfolio securities, under circumstances where it may be considered to
be an underwriter under the Securities Act of 1933.

The above limitations cannot be changed unless authorized by the "vote of a
majority of its outstanding voting securities," as defined by the Investment
Company Act. The following limitations, however, may be changed by the Board
without shareholder approval. Shareholders will be notified before any material
change in these limitations becomes effective.

Pledging Assets

The Fund will not mortgage, pledge or hypothecate any of its assets, provided
that this shall not apply to the transfer of securities in connection with any
permissible borrowing or to collateral arrangements in connection with
permissible activities.

Buying on Margin

The Fund will not purchase securities on margin, provided that the Fund may
obtain short-term credits necessary for the clearance of purchases and sales of
securities.

Investing in Illiquid Securities

The Fund will not purchase securities for which there is no readily available
market, or enter into repurchase agreements or purchase time deposits maturing
in more than seven days, if immediately after and as a result, the value of such
securities would exceed, in the aggregate, 10% of the Fund's net assets.

For purposes of the above policy concerning concentration, in conformity with an
SEC position, the Fund considers "bank instruments" to be limited to instruments
of domestic banks.

Regulatory Compliance

The Trust may follow non-fundamental operational policies that are more
restrictive than its fundamental investment limitations, as set forth in the
prospectus and this Statement of Additional Information, in order to comply with
applicable laws and regulations, including the provisions of and regulations
under the Investment Company Act of 1940. In particular, the Trust will comply
with the various requirements of Rule 2a-7 (the "Rule"), which regulates money
market mutual funds. The Trust will determine the effective maturity of its
investments according to the Rule. The Trust may change these operational
policies to reflect changes in the laws and regulations without the approval of
its shareholders.


DETERMINING MARKET VALUE OF SECURITIES
The Trustees have decided that the best method for determining the value of
portfolio instruments is amortized cost. Under this method, portfolio
instruments are valued at the acquisition cost as adjusted for amortization of
premium or accumulation of discount rather than at current market value.
Accordingly, neither the amount of daily income nor the net asset value is
affected by any unrealized appreciation or depreciation of the portfolio. In
periods of declining interest rates, the indicated daily yield on shares of the
Fund computed by dividing the annualized daily income on the Fund's portfolio by
the net asset value computed as above may tend to be higher than a similar
computation made by using a method of valuation based upon market prices and
estimates. In periods of rising interest rates, the opposite may be true.

The Fund's use of the amortized cost method of valuing portfolio instruments
depends on its compliance with certain conditions in the Rule. Under the Rule,
the Trustees must establish procedures reasonably designed to stabilize the net
asset value per share, as computed for purposes of distribution and redemption,
at $1.00 per share, taking into account current market conditions and the Fund's
investment objective. The procedures include monitoring the relationship between
the amortized cost value per share and the net asset value per share based upon
available indications of market value. The Trustees will decide what, if any,
steps should be taken if there is a difference of more than 0.5 of 1% between
the two values. The Trustees will take any steps they consider appropriate (such
as redemption in kind or shortening the average portfolio maturity) to minimize
any material dilution or other unfair results arising from differences between
the two methods of determining net asset value.


WHAT DO SHARES COST?

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.


REDUCING OR ELIMINATING THE CONTINGENT DEFERRED SALES CHARGE
These reductions or eliminations are offered because: no sales commissions have
been advanced to the investment professional selling Shares; the shareholder has
already paid a Contingent Deferred Sales Charge (CDSC); or nominal sales efforts
are associated with the original purchase of Shares.

Upon notification to the Distributor or the Fund's transfer agent, no CDSC will
be imposed on redemptions:

o    following  the death or  post-purchase  disability,  as  defined in Section
     72(m)(7)  of the  Internal  Revenue  Code of 1986,  of the  last  surviving
     shareholder;

o  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;

o    which  are  qualifying  redemptions  of Class B Shares  under a  Systematic
     Withdrawal Program;

o    of Shares  that  represent  a  reinvestment  within  120 days of a previous
     redemption;

o  of Shares held by the Trustees, employees, and sales representatives of the
   Fund, the Adviser, the Distributor and their affiliates; employees of any
   investment professional that sells Shares according to a sales agreement with
   the Distributor; and the immediate family members of the above persons; and

o  of Shares originally purchased through a bank trust department, a registered
   investment adviser or retirement plans where the third party administrator
   has entered into certain arrangements with the Distributor or its affiliates,
   or any other investment professional, to the extent that no payments were
   advanced for purchases made through these entities.




<PAGE>



HOW IS THE FUND SOLD?

Under the  Distributor's  Contract  with the Fund,  the  Distributor  (Federated
Securities Corp.) offers Shares on a continuous, best-efforts basis.


RULE 12B-1 PLAN
As a compensation-type plan, the Rule 12b-1 Plan is designed to pay the
Distributor (who may then pay investment professionals such as banks,
broker/dealers, trust departments of banks, and registered investment advisers)
for marketing activities (such as advertising, printing and distributing
prospectuses, and providing incentives to investment professionals) to promote
sales of Shares so that overall Fund assets are maintained or increased. This
helps the Fund achieve economies of scale, reduce per share expenses, and
provide cash for orderly portfolio management and Share redemptions. In
addition, the Fund's service providers that receive asset-based fees also
benefit from stable or increasing Fund assets.

The Fund may compensate the Distributor more or less than its actual marketing
expenses. In no event will the Fund pay for any expenses of the Distributor that
exceed the maximum Rule 12b-1 Plan fee.

For some classes of Shares, the maximum rule 12b-1 Plan fee that can be paid in
any one year may not be sufficient to cover the marketing related expenses the
Distributor has incurred. Therefore, it may take the Distributor a number of
years to recoup these expenses.

Federated and its subsidiaries may benefit from arrangements where the Rule
12b-1 Plan fees related to Class B Shares may be paid to third parties who have
advanced commissions to investment professionals.


SHAREHOLDER SERVICES
The Fund may pay Federated Shareholder Services Company, a subsidiary of
Federated Investors, Inc. (Federated), for providing shareholder services and
maintaining shareholder accounts. Federated Shareholder Services Company may
select others to perform these services for their customers and may pay them
fees.


SUPPLEMENTAL PAYMENTS
Investment professionals may be paid fees out of the assets of the Distributor
and/or Federated Shareholder Services Company (but not out of Fund assets). The
Distributor and/or Federated Shareholder Services Company may be reimbursed by
the Adviser or its affiliates.

Investment professionals receive such fees for providing distribution-related or
shareholder services such as sponsoring sales, providing sales literature,
conducting training seminars for employees, and engineering sales-related
computer software programs and systems. Also, investment professionals may be
paid cash or promotional incentives, such as reimbursement of certain expenses
relating to attendance at informational meetings about the Fund or other special
events at recreational-type facilities, or items of material value. These
payments will be based upon the amount of Shares the investment professional
sells or may sell and/or upon the type and nature of sales or marketing support
furnished by the investment professional.


SUBACCOUNTING SERVICES

Certain investment professionals may wish to use the transfer agent's
subaccounting system to minimize their internal recordkeeping requirements. The
transfer agent may charge a fee based on the level of subaccounting services
rendered. Investment professionals holding Shares in a fiduciary, agency,
custodial, or similar capacity may charge or pass through subaccounting fees as
part of or in addition to normal trust or agency account fees. They may also
charge fees for other services that may be related to the ownership of Shares.
This information should, therefore, be read together with any agreement between
the customer and the investment professional about the services provided, the
fees charged for those services, and any restrictions and limitations imposed.


REDEMPTION IN KIND

Although the Fund intends to pay Share redemptions in cash, it reserves the
right, as described below, to pay the redemption price in whole or in part by a
distribution of the Fund's portfolio securities.

Because the Fund has elected to be governed by Rule 18f-1 under the Investment
Company Act of 1940, the Fund is obligated to pay Share redemptions to any one
shareholder in cash only up to the lesser of $250,000 or 1% of the net assets
represented by such Share class during any 90-day period.

Any Share redemption payment greater than this amount will also be in cash
unless the Fund's Board determines that payment should be in kind. In such a
case, the Fund will pay all or a portion of the remainder of the redemption in
portfolio securities, valued in the same way as the Fund determines its NAV. The
portfolio securities will be selected in a manner that the Fund's Board deems
fair and equitable and, to the extent available, such securities will be readily
marketable.

Redemption in kind is not as liquid as a cash redemption. If redemption is made
in kind, shareholders receiving the portfolio securities and selling them before
their maturity could receive less than the redemption value of the securities
and could incur certain transaction costs.


MASSACHUSETTS PARTNERSHIP LAW

Under certain circumstances, shareholders may be held personally liable as
partners under Massachusetts law for obligations of the Trust. To protect its
shareholders, the Trust has filed legal documents with Massachusetts that
expressly disclaim the liability of its shareholders for acts or obligations of
the Trust.

In the unlikely event a shareholder is held personally liable for the Trust's
obligations, the Trust is required by the Declaration of Trust to use its
property to protect or compensate the shareholder. On request, the Trust will
defend any claim made and pay any judgment against a shareholder for any act or
obligation of the Trust. Therefore, financial loss resulting from liability as a
shareholder will occur only if the Trust itself cannot meet its obligations to
indemnify shareholders and pay judgments against them.


ACCOUNT AND SHARE INFORMATION


VOTING RIGHTS
Each share of the Fund gives the shareholder one vote in Trustee elections and
other matters submitted to shareholders for vote.

All Shares of the Fund have equal voting rights, except that in matters
affecting only a particular Fund or class, only Shares of the Fund or class are
entitled to vote.

Trustees may be removed by the Board or by shareholders at a special meeting. A
special meeting of shareholders will be called by the Board upon the written
request of shareholders who own at least 10% of the Fund's outstanding shares of
all series entitled to vote.

As of _________, 1999, the following shareholders owned of record, beneficially,
or both, 5% or more of outstanding Shares:
- -------------------------

Shareholders owning 25% or more of outstanding Shares may be in control and be
able to affect the outcome of certain matters presented for a vote of
shareholders.




<PAGE>



TAX INFORMATION


FEDERAL INCOME TAX
The Fund intends to meet requirements of Subchapter M of the Internal Revenue
Code applicable to regulated investment companies. If these requirements are not
met, it will not receive special tax treatment and will pay federal income tax.

The Fund will be treated as a single separate entity for federal income tax
purposes so that income earned and capital gains and losses realized by the
Trust's other portfolios will be separate from those realized by the Fund.

INVESTMENT ADVISER
The Adviser conducts investment research and makes investment decisions for the
Fund.

The Adviser is a wholly owned subsidiary of Federated.

The Adviser shall not be liable to the Trust or any Fund 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 Trust.


Other Related Services
Affiliates of the Adviser may, from time to time, provide certain electronic
equipment and software to institutional customers in order to facilitate the
purchase of Fund Shares offered by the Distributor.


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. 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. In selecting among firms believed to meet these
criteria, the Adviser may give consideration to those firms which have sold or
are selling Shares of the Fund and other funds distributed by the Distributor
and its affiliates. The Adviser makes decisions on portfolio transactions and
selects brokers and dealers subject to review by the Fund's Board.


Research Services
Investment decisions for the Fund are made independently from those of other
accounts managed by the Adviser. When the Fund and one or more of those accounts
invests in, or disposes of, the same security, available investments or
opportunities for sales will be allocated among the Fund and the account(s) in a
manner believed by the Adviser to be equitable. While the coordination and
ability to participate in volume transactions may benefit the Fund, it is
possible that this procedure could adversely impact the price paid or received
and/or the position obtained or disposed of by the Fund.

personnel and services (including certain legal and financial reporting
services) necessary to operate the Fund. Federated Services Company provides

Federated Services Company may voluntarily waive a portion of its fee and may
reimburse the Fund for expenses.

Federated Services Company also provides certain accounting and recordkeeping
services with respect to the Fund's portfolio investments for a fee based on
Fund assets plus out-of-pocket expenses.

HOW DOES THE FUND MEASURE PERFORMANCE?

The Fund may advertise Share performance by using the Securities and Exchange
Commission's (SEC) standard method for calculating performance applicable to all
mutual funds. The SEC also permits this standard performance information to be
accompanied by non-standard performance information.

Unless otherwise stated, any quoted Share performance reflects the effect of
non-recurring charges, such as maximum sales charges, which, if excluded, would
increase the total return and yield. The performance of Shares depends upon such
variables as: portfolio quality; average portfolio maturity; type and value of
portfolio securities; changes in interest rates; changes or differences in the
Fund's or any class of Shares' expenses; and various other factors.

Share performance fluctuates on a daily basis largely because net earnings
fluctuate daily. Both net earnings and offering price per Share are factors in
the computation of yield and total return.

TOTAL RETURN
Total return represents the change (expressed as a percentage) in the value of
Shares over a specific period of time, and includes the investment of income and
capital gains distributions.

The average annual total return for Shares 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 NAV 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 the annual reinvestment of all
dividends and distributions.

YIELD

The yield of Shares is based upon the seven days ending on the day of the
calculation, called the "base period." This yield is calculated by: determining
the net change in the value of a hypothetical account with a balance of one
Share at the beginning of the base period, with the net change excluding capital
changes but including the value of any additional Shares purchased with
dividends earned from the original one Share and all dividends declared on the
original and any purchased Shares; dividing the net change in the account's
value by the value of the account at the beginning of the base period to
determine the base period return; and multiplying the base period return by
365/7. The effective yield is calculated by compounding the unannualized
base-period return by: adding one to the base-period return, raising the sum to
the 365/7th power; and subtracting one from the result.

To the extent investment professionals and broker/dealers charge fees in
connection with services provided in conjunction with an investment in Shares,
the Share performance is lower for shareholders paying those fees.
