</TABLE>

(1) The management fee has been reduced to reflect the voluntary waiver of a
    portion of the management fee. The adviser can terminate this voluntary
    waiver at any time at its sole discretion. The maximum management fee is
    0.20%.

(2) The shareholder services fee has been reduced to reflect the voluntary
    waiver of the shareholder services fee. The shareholder service provider
    can terminate this voluntary waiver at any time at its sole discretion.
    The maximum shareholder services fee is 0.25%.

(3) The total operating expenses would have been 0.55% absent the voluntary
    waiver of a portion of the management fee and the shareholder services
    fee.

The purpose of this table is to assist an investor in understanding the
various costs and expenses that a shareholder of the Institutional Shares of
the Fund will bear, either directly or indirectly. For more complete
descriptions of the various costs and expenses, see "Fund Information" and
"How to Purchase Shares." Wire-transferred redemptions of less than $5,000
may be subject to additional fees.

EXAMPLE

You would pay the following expenses on a $1,000 investment, assuming (1) 5%
annual return and (2) redemption at the end of each time period.

1 Year            $2
3 Years           $6
5 Years          $11
10 Years         $26

THE ABOVE EXAMPLE SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR
FUTURE EXPENSES. ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN.

                            GENERAL INFORMATION

The Trust was established as a Massachusetts business trust under a
Declaration of Trust dated October 3, 1988. The Declaration of Trust permits
the Trust to offer separate series of shares representing interests in
separate portfolios of securities. The shares in any one portfolio may be
offered in separate classes. With respect to this Fund, as of the date of
this prospectus, the Board of Trustees (the "Trustees") has established two
classes of shares known as Institutional Shares and Institutional Service
Shares. This prospectus relates only to Institutional Shares of the Fund,
which are designed primarily for entities holding shares in an agency or
fiduciary capacity, financial institutions, financial intermediaries, and
institutional investors as a convenient means of accumulating an interest in
a professionally managed portfolio investing only in short-term U.S.
government securities. A minimum initial investment of $1,000,000 is
required.

The Fund attempts to stabilize the value of a share at $1.00. Shares are
currently sold and redeemed at that price.

                           INVESTMENT INFORMATION

INVESTMENT OBJECTIVE

The investment objective of the Fund is to provide current income consistent
with stability of principal. This investment objective cannot be changed
without shareholder approval. While there is no assurance that the Fund will
achieve its investment objective, it endeavors to do so by complying with
the diversification and other requirements of Rule 2a-7 under the Investment
Company Act of 1940 which regulates money market mutual funds and by
following the investment policies described in this prospectus.

INVESTMENT POLICIES

The Fund pursues its investment objective by investing only in a portfolio
of U.S. government securities maturing in 13 months or less. The average
maturity of the securities in the Fund's portfolio, computed on a
dollar-weighted basis, will be 90 days or less. Unless indicated otherwise,
the investment policies may be changed by the Trustees without shareholder
approval. Shareholders will be notified before any material change in these
policies becomes effective.

ACCEPTABLE INVESTMENTS

The Fund invests only in U.S. government securities. These instruments are
either issued or guaranteed by the U.S. government, its agencies, or
instrumentalities. These securities include, but are not limited to:

* direct obligations of the U.S. Treasury, such as U.S. Treasury bills,
  notes, and bonds;

* notes, bonds, and discount notes issued or guaranteed by U.S. government
  agencies and instrumentalities supported by the full faith and credit of the
  United States;

* notes, bonds, and discount notes of U.S. government agencies or
  instrumentalities which receive or have access to federal funding; and

* notes, bonds, and discount notes of other U.S. government
  instrumentalities supported only by the credit of the instrumentalities.

Some obligations issued or guaranteed by agencies or instrumentalities of
the U.S. government are backed by the full faith and credit of the U.S.
Treasury. No assurances can be given that the U.S. government will provide
financial support to other agencies or instrumentalities, since it is not
obligated to do so. These instrumentalities are supported by:

* the issuer's right to borrow an amount limited to a specific line of
  credit from the U.S. Treasury;

* discretionary authority of the U.S. government to purchase certain
  obligations of an agency or instrumentality; or

* the credit of the agency or instrumentality.

REPURCHASE AGREEMENTS

Certain securities in which the Fund invests may be purchased pursuant to
repurchase agreements. Repurchase agreements are arrangements in which
banks, broker/dealers, and other recognized financial institutions sell
securities to the Fund and agree at the time of sale to repurchase them at a
mutually agreed upon time and price. To the extent that the seller does not
repurchase the securities from the Fund, the Fund could receive less than
the repurchase price on any sale of such securities.

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

The Fund may purchase securities on a when-issued or delayed delivery basis.
These transactions are arrangements in which the Fund purchases securities
with payment and delivery scheduled for a future time. The seller's failure
to complete these transactions may cause the Fund to miss a price or yield
considered to be advantageous. Settlement dates may be a month or more after
entering into these transactions, and the market values of the securities
purchased may vary from the purchase prices.

The Fund may dispose of a commitment prior to settlement if the adviser
deems it appropriate to do so. In addition, the Fund may enter into
transactions to sell its purchase commitments to third parties at current
market values and simultaneously acquire other commitments to purchase
similar securities at later dates. The Fund may realize short-term profits
or losses upon the sale of such commitments.

LENDING OF PORTFOLIO SECURITIES

In order to generate additional income, the Fund may lend its portfolio
securities on a short-term or long-term basis, or both, to broker/dealers,
banks, or other institutional borrowers of securities. The Fund will only
enter into loan arrangements with broker/dealers, banks, or other
institutions which the adviser has determined are creditworthy under
guidelines established by the Fund's Trustees and will receive collateral at
all times equal to at least 100% of the value of the securities loaned.
There is the risk that when lending portfolio securities, the securities may
not be available to the Fund on a timely basis and the Fund may, therefore,
lose the opportunity to sell the securities at a desirable price. In
addition, in the event that a borrower of securities would file for
bankruptcy or become insolvent, disposition of the securities may be delayed
pending court action.

INVESTMENT LIMITATIONS

The Fund will not borrow money directly or through reverse repurchase
agreements (arrangements in which the Fund sells a money market instrument
for a percentage of its cash value with an agreement to buy it back on a set
date) or pledge securities except, under certain circumstances, the Fund may
borrow up to one-third of the value of its total assets and pledge up to 15%
of the value of those assets to secure such borrowings.

The above investment limitations cannot be changed without shareholder
approval. As a matter of non-fundamental policy, the Fund does not intend to
engage in reverse repurchase agreements. The Fund will notify shareholders
prior to any change in this policy. The following limitation, however, may
be changed by the Trustees without shareholder approval. Shareholders will
be notified before any material change in this limitation becomes effective.

The Fund will not invest more than 10% of its net assets in illiquid
securities, including repurchase agreements providing for settlement in more
than seven days after notice.

                              FUND INFORMATION

MANAGEMENT OF THE FUND

BOARD OF TRUSTEES

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

INVESTMENT ADVISER

Investment decisions for the Fund are made by Federated Management, the
Fund's investment adviser, subject to direction by the Trustees. The adviser
continually conducts investment research and supervision for the Fund and is
responsible for the purchase and sale of portfolio instruments.

ADVISORY FEES

The adviser receives an annual investment advisory fee equal to 0.20% of the
Fund's average daily net assets. The adviser may voluntarily choose to waive
a portion of its fee or reimburse other expenses of the Fund, but reserves
the right to terminate such waiver or reimbursement at any time at its sole
discretion.

ADVISER'S BACKGROUND

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

Federated Management and other subsidiaries of Federated Investors serve as
investment advisers to a number of investment companies and private
accounts. Certain other subsidiaries also provide administrative services to
a number of investment companies. With over $110 billion invested across
over 300 funds under management and/or administration by its subsidiaries,
as of December 31, 1996, Federated Investors is one of the largest mutual
fund investment managers in the United States. With more than 2,000
employees, Federated continues to be led by the management who founded the
company in 1955. Federated funds are presently at work in and through 4,500
financial institutions nationwide.

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

DISTRIBUTION OF INSTITUTIONAL SHARES

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

SHAREHOLDER SERVICES

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

SUPPLEMENTAL PAYMENTS TO FINANCIAL INSTITUTIONS

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

ADMINISTRATION OF THE FUND

ADMINISTRATIVE SERVICES

Federated Services Company, a subsidiary of Federated Investors, provides
administrative personnel and services (including certain legal and financial
reporting services) necessary to operate the Fund at an annual rate which
relates to the average aggregate daily net assets of all funds advised by

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

                              NET ASSET VALUE

The Fund attempts to stabilize the net asset value of shares at $1.00 by
valuing the portfolio securities using the amortized cost method. The net
asset value per share is determined by subtracting liabilities attributable
to Institutional Shares from the value of Fund assets attributable to
Institutional Shares, and dividing the remainder by the number of
Institutional Shares outstanding. The Fund cannot guarantee that its net
asset value will always remain at $1.00 per share.

The net asset value is determined at 5:00 p.m. (Eastern time), Monday
through Friday, except on New Year's Day, Martin Luther King Day,
Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day,
Thanksgiving Day, and Christmas Day.

                           HOW TO PURCHASE SHARES

Shares are sold at their net asset value, without a sales charge, next
determined after an order is received, on days on which the New York Stock
Exchange is open for business. Shares may be purchased either by wire or by
check. The Fund reserves the right to reject any purchase request.

To make a purchase, open an account by calling Federated Securities Corp.
Information needed to establish the account will be taken by telephone. The
minimum initial investment is $1,000,000. However, an account may be opened
with a smaller amount as long as the minimum is reached within one year of
opening the account. Financial institutions may impose different minimum
investment requirements on their customers.

PURCHASING SHARES BY WIRE

Shares may be purchased by Federal Reserve wire by calling the Fund before
5:00 p.m. (Eastern time) to place an order. The order is considered received
immediately. Payment by federal funds must be received before 5:00 p.m.
(Eastern time) that day. Federal funds should be wired as follows: Federated
Shareholder Services Company, c/o State Street Bank and Trust Company,
Boston, MA; Attention: EDGEWIRE; For Credit to: Government Obligations Fund
- -- Institutional Shares; Fund Number (this number can be found on the
account statement or by contacting the Fund); Group Number or Order Number;
Nominee or Institution Name; and ABA Number 011000028. Shares cannot be
purchased by wire on holidays when wire transfers are restricted. Questions
on wire purchases should be directed to your shareholder services
representative at the telephone number listed on your account statement.

PURCHASING SHARES BY CHECK

Shares may be purchased by sending a check to Federated Shareholder Services
Company, P.O. Box 8600, Boston, MA 02266-8600. The check should be made
payable to: Government Obligations Fund -- Institutional Shares. 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.

INVEST-BY-PHONE

Once an account has been opened, a shareholder may use invest-by-phone for
investments if an authorization form has been filed with Federated
Shareholder Services Company, the transfer agent for shares of the Fund.
Approximately two weeks after sending the form to Federated Shareholder
Services Company, the shareholder may call Federated Shareholder Services
Company to purchase shares. Federated Shareholder Services Company will send
a request for monies to the shareholder's commercial bank, savings bank, or
credit union ("bank") via the Automated Clearing House. The shareholder's
bank, which must be an Automated Clearing House member, will then forward
the monies to Federated Shareholder Services Company. The purchase is
normally entered the next business day after the initial phone request. For
further information and an application, call the Fund.

                            HOW TO REDEEM SHARES

Shares are redeemed at their net asset value next determined after Federated
Shareholder Services Company receives the redemption request. Redemptions
will be made on days on which the Fund computes its net asset value.
Redemption requests must be received in proper form and can be made as
described below.

REDEEMING SHARES BY TELEPHONE

Redemptions in any amount may be made by calling the Fund provided the Fund
has a properly completed authorization form. These forms can be obtained
from Federated Securities Corp. Proceeds from redemption requests received
before 5:00 p.m. (Eastern time) will be wired the same day to the
shareholder's account at a domestic commercial bank which is a member of the
Federal Reserve System, but will not include that day's dividend. Proceeds
from redemption requests on holidays when wire transfers are restricted will
be wired the following business day. Questions about telephone redemptions on
days when wire transfers are restricted should be directed to your
shareholder services representative at the telephone number listed on your
account statement.

Telephone instructions may be recorded and if reasonable procedures are not
followed by the Fund, it may be liable for losses due to unauthorized or
fraudulent telephone instructions.

In the event of drastic economic or market changes, a shareholder may
experience difficulty in redeeming by telephone. If this occurs, "Redeeming
Shares by Mail" should be considered. If at any time the Fund shall
determine it necessary to terminate or modify the telephone redemption
privilege, shareholders would be promptly notified.

REDEEMING SHARES BY MAIL

Shares may be redeemed in any amount by mailing a written request to:
Federated Shareholder Services Company, P.O. Box 8600, Boston, MA
02266-8600. If share certificates have been issued, they should be sent
unendorsed with the written request by registered or certified mail to the
address noted above.

The written request should state: the Fund name and the class designation;
the account name as registered with the Fund; the account number; and the
number of shares to be redeemed or the dollar amount requested. All owners
of the account must sign the request exactly as the shares are registered.
Normally, a check for the proceeds is mailed within one business day, but in
no event more than seven days, after the receipt of a proper written
redemption request. Dividends are paid up to and including the day that a
redemption request is processed.

Shareholders requesting a redemption of any amount to be sent to an address
other than that on record with the Fund or a redemption payable other than
to the shareholder of record must have their signatures guaranteed by a
commercial or savings bank, trust company or savings association whose
deposits are insured by an organization which is administered by the Federal
Deposit Insurance Corporation; a member firm of a domestic stock exchange;
or any other "eligible guarantor institution," as defined in the Securities
Exchange Act of 1934. The Fund does not accept signatures guaranteed by a
notary public.

                       ACCOUNT AND SHARE INFORMATION

DIVIDENDS

Dividends are declared daily and paid monthly. Dividends are automatically
reinvested on payment dates in additional shares of the Fund unless cash
payments are requested by writing to the Fund. Shares purchased by wire
before 5:00 p.m. (Eastern time) begin earning dividends that day. Shares
purchased by check begin earning dividends the day after the check is
converted into federal funds.

CAPITAL GAINS

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 will distribute in cash or additional shares any
realized net long-term capital gains at least once every 12 months.

CONFIRMATIONS AND ACCOUNT STATEMENTS

Shareholders will receive detailed confirmations of transactions (except for
systematic program transactions). In addition, shareholders will receive
periodic statements reporting all account activity, including dividends
paid. The Fund will not issue share certificates.

ACCOUNTS WITH LOW BALANCES

Due to the high cost of maintaining accounts with low balances, the Fund may
redeem shares in any account, except accounts maintained by retirement
plans, and pay the proceeds to the shareholder if the account balance falls
below a required minimum value of $1,000,000 due to shareholder redemptions.
Before shares are redeemed to close an account, the shareholder is notified
in writing and allowed 30 days to purchase additional shares to meet the
minimum requirement.

VOTING RIGHTS

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

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

                              TAX INFORMATION

FEDERAL INCOME TAX

The Fund will pay no federal income tax because it expects to meet
requirements of the Internal Revenue Code applicable to regulated investment
companies and to receive the special tax treatment afforded to such
companies. The Fund will be treated as a single, separate entity for federal
income tax purposes so that income (including capital gains) and losses
realized by the Trust's other portfolios will not be combined for tax
purposes with those realized by the Fund.

Unless otherwise exempt, shareholders are required to pay federal income tax
on any dividends and other distributions received. This applies whether
dividends and distributions are received in cash or as additional shares.

STATE AND LOCAL TAXES

In the opinion of Houston, Donnelly & Meck, counsel to the Trust, Fund
shares may be subject to personal property taxes imposed by counties,
municipalities, and school districts in Pennsylvania to the extent that the
portfolio securities in the Fund would be subject to such taxes if owned
directly by residents of those jurisdictions.

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

                          OTHER CLASSES OF SHARES

The Fund also offers other classes. Institutional Service Shares are sold at
net asset value primarily to financial institutions, financial
intermediaries, and other institutional investors, and are subject to a
minimum initial investment of $1,000,000.

All classes are subject to certain of the same expenses.

Institutional Service Shares are distributed with no 12b-1 Plan but are
subject to shareholder services fees.

Expense differences between classes may affect the performance of each
class.

To obtain more information and a prospectus for any other class, investors
may call 1-800-341-7400.

                          PERFORMANCE INFORMATION

From time to time, the Fund advertises its yield, effective yield and total
return. The performance figures will be calculated separately for each class
of shares.

Yield represents the annualized rate of income earned on an investment over
a seven-day period. It is the annualized dividends earned during the period
on an investment shown as a percentage of the investment. The effective
yield is calculated similarly to the yield, but when annualized, the income
earned by an investment is assumed to be reinvested daily. The effective
yield will be slightly higher than the yield because of the compounding
effect of this assumed reinvestment.

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

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

                       NOTES TO FINANCIAL STATEMENTS
                         GOVERNMENT OBLIGATIONS FUND

                               JULY 31, 1997

ORGANIZATION

Money Market Obligations Trust (the "Trust") is registered under the
Investment Company Act of 1940, as amended (the "Act") as an open-end,
management investment company. The Trust consists of six portfolios. The
financial statements included herein are only those of Government
Obligations Fund (the "Fund"). The financial statements of the other
portfolios are presented separately. The assets of each portfolio are
segregated and a shareholder's interest is limited to the portfolio in which
shares are held. The investment objective of the Fund is to provide current
income consistent with stability of principal.

The Fund offers two classes of shares: Institutional Shares and
Institutional Service Shares.

SIGNIFICANT ACCOUNTING POLICIES

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

INVESTMENT VALUATIONS

The Fund uses the amortized cost method to value its portfolio securities in
accordance with Rule 2a-7 under the Act.

REPURCHASE AGREEMENTS

It is the policy of the Fund to require the custodian bank to take
possession, to have legally segregated in the Federal Reserve Book Entry
System, or to have segregated within the custodian bank's vault, all
securities held as collateral under repurchase agreement transactions.
Additionally, procedures have been established by the Fund to monitor, on a
daily basis, the market value of each repurchase agreement's collateral to
ensure that the value of collateral at least equals the repurchase price to
be paid under the repurchase agreement transaction.

The Fund will only enter into repurchase agreements with banks and other
recognized financial institutions, such as broker/
dealers, which are deemed by the Fund's adviser to be creditworthy pursuant
to the guidelines and/or standards reviewed or established by the Board of
Trustees (the "Trustees"). Risks may arise from the potential inability of
counterparties to honor the terms of the repurchase agreement. Accordingly,
the Fund could receive less than the repurchase price on the sale of
collateral securities.

INVESTMENT INCOME, EXPENSES AND DISTRIBUTIONS

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

FEDERAL TAXES

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

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

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

USE OF ESTIMATES

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

OTHER

Investment transactions are accounted for on the trade date.

SHARES OF BENEFICIAL INTEREST

The Declaration of Trust permits the Trustees to issue an unlimited number
of full and fractional shares of beneficial interest (without par value) for
each class of shares. At July 31, 1997, capital paid-in aggregated
$4,230,260,373. Transactions in shares were as follows:

                  REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Shareholders and Board of Trustees of
MONEY MARKET OBLIGATIONS TRUST
(Government Obligations Fund):

We have audited the accompanying statement of assets and liabilities of
Government Obligations Fund (an investment portfolio of Money Market
Obligations Trust, a Massachusetts business trust), including the schedule
of portfolio investments, as of July 31, 1997, the related statement of
operations for the year then ended, the statement of changes in net assets
for each of the two years in the period then ended, and the financial
highlights for the periods presented. These financial statements and
financial highlights are the responsibility of the Trust's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements and
financial highlights are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures
in the financial statements. Our procedures included confirmation of
securities owned as of July 31, 1997, by correspondence with the custodian
and brokers. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits provide
a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of
Government Obligations Fund (an investment portfolio of Money Market
Obligations Trust) as of July 31, 1997, the results of its operations for
the year then ended, the changes in its net assets for each of the two years
in the period then ended, and its financial highlights for the periods
presented, in conformity with generally accepted accounting principles.

(1) The management fee has been reduced to reflect the voluntary waiver of a
    portion of the management fee. The adviser can terminate this voluntary
    waiver at any time at its sole discretion. The maximum management fee is
    0.20%.

(2) The total operating expenses would have been 0.55% absent the voluntary
    waiver of a portion of the management fee.

The purpose of this table is to assist an investor in understanding the
various costs and expenses that a shareholder of the Institutional Service
Shares of the Fund will bear, either directly or indirectly. For more
complete descriptions of the various costs and expenses, see "Fund
Information" and "How to Purchase Shares." Wire-transferred redemptions of
less than $5,000 may be subject to additional fees.

EXAMPLE

You would pay the following expenses on a $1,000 investment, assuming (1) 5%
annual return and (2) redemption at the end of each time period.

 1 Year         $ 5
 3 Years        $14
 5 Years        $25
 10 Years       $57

THE ABOVE EXAMPLE SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR
FUTURE EXPENSES. ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN.

                            GENERAL INFORMATION

The Trust was established as a Massachusetts business trust under a
Declaration of Trust dated October 3, 1988. The Declaration of Trust permits
the Trust to offer separate series of shares representing interests in
separate portfolios of securities. The shares in any one portfolio may be
offered in separate classes. With respect to this Fund, as of the date of
this prospectus, the Board of Trustees (the "Trustees") has established two
classes of shares known as Institutional Service Shares and Institutional
Shares. This prospectus relates only to Institutional Service Shares of the
Fund, which are designed primarily for financial institutions, financial
intermediaries, and institutional investors as a convenient means of
accumulating an interest in a professionally managed portfolio investing
only in short-term U.S. government securities. A minimum initial investment
of $1,000,000 is required.

The Fund attempts to stabilize the value of a share at $1.00. Shares are
currently sold and redeemed at that price.

                           INVESTMENT INFORMATION

INVESTMENT OBJECTIVE

The investment objective of the Fund is to provide current income consistent
with stability of principal. This investment objective cannot be changed
without shareholder approval. While there is no assurance that the Fund will
achieve its investment objective, it endeavors to do so by complying with
the diversification and other requirements of Rule 2a-7 under the Investment
Company Act of 1940 which regulates money market mutual funds and by
following the investment policies described in this prospectus.

INVESTMENT POLICIES

The Fund pursues its investment objective by investing only in a portfolio
of U.S. government securities maturing in 13 months or less. The average
maturity of the securities in the Fund's portfolio, computed on a
dollar-weighted basis, will be 90 days or less. Unless indicated otherwise,
the investment policies may be changed by the Trustees without shareholder
approval. Shareholders will be notified before any material change in these
policies becomes effective.

ACCEPTABLE INVESTMENTS

The Fund invests only in U.S. government securities. These instruments are
either issued or guaranteed by the U.S. government, its agencies, or
instrumentalities. These securities include, but are not limited to:

* direct obligations of the U.S. Treasury, such as U.S. Treasury bills,
  notes, and bonds;

* notes, bonds, and discount notes issued or guaranteed by U.S. government
  agencies and instrumentalities supported by the full faith and credit of the
  United States;

* notes, bonds, and discount notes of U.S. government agencies or
  instrumentalities which receive or have access to federal funding; and

* notes, bonds, and discount notes of other U.S. government
  instrumentalities supported only by the credit of the instrumentalities.

Some obligations issued or guaranteed by agencies or instrumentalities of
the U.S. government are backed by the full faith and credit of the U.S.
Treasury. No assurances can be given that the U.S. government will provide
financial support to other agencies or instrumentalities, since it is not
obligated to do so. These instrumentalities are supported by:

* the issuer's right to borrow an amount limited to a specific line of
  credit from the U.S. Treasury;

* discretionary authority of the U.S. government to purchase certain
  obligations of an agency or instrumentality; or

* the credit of the agency or instrumentality.

REPURCHASE AGREEMENTS

Certain securities in which the Fund invests may be purchased pursuant to
repurchase agreements. Repurchase agreements are arrangements in which
banks, broker/dealers, and other recognized financial institutions sell
securities to the Fund and agree at the time of sale to repurchase them at a
mutually agreed upon time and price. To the extent that the seller does not
repurchase the securities from the Fund, the Fund could receive less than
the repurchase price on any sale of such securities.

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

The Fund may purchase securities on a when-issued or delayed delivery basis.
These transactions are arrangements in which the Fund purchases securities
with payment and delivery scheduled for a future time. The seller's failure
to complete these transactions may cause the Fund to miss a price or yield
considered to be advantageous. Settlement dates may be a month or more after
entering into these transactions, and the market values of the securities
purchased may vary from the purchase prices.

The Fund may dispose of a commitment prior to settlement if the adviser
deems it appropriate to do so. In addition, the Fund may enter into
transactions to sell its purchase commitments to third parties at current
market values and simultaneously acquire other commitments to purchase
similar securities at later dates. The Fund may realize short-term profits
or losses upon the sale of such commitments.

LENDING OF PORTFOLIO SECURITIES

In order to generate additional income, the Fund may lend its portfolio
securities on a short-term or long-term basis, or both, to broker/dealers,
banks, or other institutional borrowers of securities. The Fund will only
enter into loan arrangements with broker/dealers, banks, or other
institutions which the adviser has determined are creditworthy under
guidelines established by the Fund's Trustees and will receive collateral at
all times equal to at least 100% of the value of the securities loaned.
There is the risk that when lending portfolio securities, the securities may
not be available to the Fund on a timely basis and the Fund may, therefore,
lose the opportunity to sell the securities at a desirable price. In
addition, in the event that a borrower of securities would file for
bankruptcy or become insolvent, disposition of the securities may be delayed
pending court action.

INVESTMENT LIMITATIONS

The Fund will not borrow money directly or through reverse repurchase
agreements (arrangements in which the Fund sells a money market instrument
for a percentage of its cash value with an agreement to buy it back on a set
date) or pledge securities except, under certain circumstances, the Fund may
borrow up to one-third of the value of its total assets and pledge up to 15%
of the value of those assets to secure such borrowings.

The above investment limitations cannot be changed without shareholder
approval. As a matter of non-fundamental policy, the Fund does not intend to
engage in reverse repurchase agreements. The Fund will notify shareholders
prior to any change in this policy. The following limitation, however, may
be changed by the Trustees without shareholder approval. Shareholders will
be notified before any material change in this limitation becomes effective.

The Fund will not invest more than 10% of its net assets in illiquid
securities, including repurchase agreements providing for settlement in more
than seven days after notice.

                              FUND INFORMATION

MANAGEMENT OF THE FUND

BOARD OF TRUSTEES

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

INVESTMENT ADVISER

Investment decisions for the Fund are made by Federated Management, the
Fund's investment adviser, subject to direction by the Trustees. The adviser
continually conducts investment research and supervision for the Fund and is
responsible for the purchase and sale of portfolio instruments.

  ADVISORY FEES
 
  The adviser receives an annual investment advisory fee equal to 0.20% of the
  Fund's average daily net assets. The adviser may voluntarily choose to waive
  a portion of its fee or reimburse other expenses of the Fund, but reserves
  the right to terminate such waiver or reimbursement at any time at its sole
  discretion.
 
  ADVISER'S BACKGROUND
 
  Federated Management, a Delaware business trust, organized on April 11,
  1989, is a registered investment adviser under the Investment Advisers Act
  of 1940. It is a subsidiary of Federated Investors. All of the Class A
  (voting) shares of Federated Investors are owned by a trust, the trustees of
  which are John F. Donahue, Chairman and Trustee of Federated Investors, Mr.
  Donahue's wife, and Mr. Donahue's son, J. Christopher Donahue, who is
  President and Trustee of Federated Investors.
 
  Federated Management and other subsidiaries of Federated Investors serve as
  investment advisers to a number of investment companies and private
  accounts. Certain other subsidiaries also provide administrative services to
  a number of investment companies. With over $110 billion invested across
  over 300 funds under management and/or administration by its subsidiaries,
  as of December 31, 1996, Federated Investors is one of the largest mutual
  fund investment managers in the United States. With more than 2,000
  employees, Federated continues to be led by the management who founded the
  company in 1955. Federated funds are presently at work in and through 4,500
  financial institutions nationwide.
 
Both the Trust and the adviser have adopted strict codes of ethics governing
the conduct of all employees who manage the Fund and its portfolio
securities. These codes recognize that such persons owe a fiduciary duty to
the Fund's shareholders and must place the interests of shareholders ahead
of the employees' own interests. Among other things, the codes: require
preclearance and periodic reporting of personal securities transactions;
prohibit personal transactions in securities being purchased or sold, or
being considered for purchase or sale, by the Fund; prohibit purchasing
securities in initial public offerings; and prohibit taking profits on
securities held for less than sixty days. Violations of the codes are
subject to review by the Trustees, and could result in severe penalties.

DISTRIBUTION OF INSTITUTIONAL SERVICE SHARES

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

SHAREHOLDER SERVICES

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

SUPPLEMENTAL PAYMENTS TO FINANCIAL INSTITUTIONS

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

ADMINISTRATION OF THE FUND

ADMINISTRATIVE SERVICES

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

 MAXIMUM            AVERAGE AGGREGATE
   FEE               DAILY NET ASSETS

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

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

                              NET ASSET VALUE

The Fund attempts to stabilize the net asset value of shares at $1.00 by
valuing the portfolio securities using the amortized cost method. The net
asset value per share is determined by subtracting liabilities attributable
to Institutional Service Shares from the value of Fund assets attributable
to Institutional Service Shares, and dividing the remainder by the number of
Institutional Service Shares outstanding. The Fund cannot guarantee that its
net asset value will always remain at $1.00 per share.

The net asset value is determined at 5:00 p.m. (Eastern time), Monday
through Friday, except on New Year's Day, Martin Luther King Day,
Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day,
Thanksgiving Day, and Christmas Day.

                           HOW TO PURCHASE SHARES

Shares are sold at their net asset value, without a sales charge, next
determined after an order is received, on days on which the New York Stock
Exchange is open for business. Shares may be purchased either by wire or by
check. The Fund reserves the right to reject any purchase request.

To make a purchase, open an account by calling Federated Securities Corp.
Information needed to establish the account will be taken by telephone. The
minimum initial investment is $1,000,000. However, an account may be opened
with a smaller amount as long as the minimum is reached within one year of
opening the account. Financial institutions may impose different minimum
investment requirements on their customers.

PURCHASING SHARES BY WIRE

Shares may be purchased by Federal Reserve wire by calling the Fund before
5:00 p.m. (Eastern time) to place an order. The order is considered received
immediately. Payment by federal funds must be received before 5:00 p.m.
(Eastern time) that day. Federal funds should be wired as follows: Federated
Shareholder Services Company, c/o State Street Bank and Trust Company,
Boston, MA; Attention: EDGEWIRE; For Credit to: Government Obligations Fund
- -- Institutional Service Shares; Fund Number (this number can be found on
the account statement or by contacting the Fund); Group Number or Order
Number; Nominee or Institution Name; and ABA Number 011000028. Shares cannot
be purchased by wire on holidays when wire transfers are restricted.
Questions on wire purchases should be directed to your shareholder services
representative at the telephone number listed on your account statement.

PURCHASING SHARES BY CHECK

Shares may be purchased by sending a check to Federated Shareholder Services
Company, P.O. Box 8600, Boston, MA 02266-8600. The check should be made
payable to: Government Obligations Fund -- Institutional Service Shares.
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.

INVEST-BY-PHONE

Once an account has been opened, a shareholder may use invest-by-phone for
investments if an authorization form has been filed with Federated
Shareholder Services Company, the transfer agent for shares of the Fund.
Approximately two weeks after sending the form to Federated Shareholder
Services Company, the shareholder may call Federated Shareholder Services
Company to purchase shares. Federated Shareholder Services Company will send
a request for monies to the shareholder's commercial bank, savings bank, or
credit union ("bank") via the Automated Clearing House. The shareholder's
bank, which must be an Automated Clearing House member, will then forward
the monies to Federated Shareholder Services Company. The purchase is
normally entered the next business day after the initial phone request. For
further information and an application, call the Fund.

                            HOW TO REDEEM SHARES

Shares are redeemed at their net asset value next determined after Federated
Shareholder Services Company receives the redemption request. Redemptions
will be made on days on which the Fund computes its net asset value.
Redemption requests must be received in proper form and can be made as
described below.

REDEEMING SHARES BY TELEPHONE

Redemptions in any amount may be made by calling the Fund provided the Fund
has a properly completed authorization form. These forms can be obtained
from Federated Securities Corp. Proceeds from redemption requests received
before 5:00 p.m. (Eastern time) will be wired the same day to the
shareholder's account at a domestic commercial bank which is a member of the
Federal Reserve System, but will not include that day's dividend. Proceeds
from redemption requests on holidays when wire transfers are restricted will
be wired the following business day. Questions about telephone redemptions
on days when wire transfers are restricted should be directed to your
shareholder services representative at the telephone number listed on your
account statement.

Telephone instructions may be recorded and if reasonable procedures are not
followed by the Fund, it may be liable for losses due to unauthorized or
fraudulent telephone instructions.

In the event of drastic economic or market changes, a shareholder may
experience difficulty in redeeming by telephone. If this occurs, "Redeeming
Shares by Mail" should be considered. If at any time the Fund shall
determine it necessary to terminate or modify the telephone redemption
privilege, shareholders would be promptly notified.

REDEEMING SHARES BY MAIL

Shares may be redeemed in any amount by mailing a written request to:
Federated Shareholder Services Company, P.O. Box 8600, Boston, MA
02266-8600. If share certificates have been issued, they should be sent
unendorsed with the written request by registered or certified mail to the
address noted above.

The written request should state: the Fund name and the class designation;
the account name as registered with the Fund; the account number; and the
number of shares to be redeemed or the dollar amount requested. All owners
of the account must sign the request exactly as the shares are registered.
Normally, a check for the proceeds is mailed within one business day, but in
no event more than seven days, after the receipt of a proper written
redemption request. Dividends are paid up to and including the day that a
redemption request is processed.

Shareholders requesting a redemption of any amount to be sent to an address
other than that on record with the Fund or a redemption payable other than
to the shareholder of record must have their signatures guaranteed by a
commercial or savings bank, trust company or savings association whose
deposits are insured by an organization which is administered by the Federal
Deposit Insurance Corporation; a member firm of a domestic stock exchange;
or any other "eligible guarantor institution," as defined in the Securities
Exchange Act of 1934. The Fund does not accept signatures guaranteed by a
notary public.

                       ACCOUNT AND SHARE INFORMATION

DIVIDENDS

Dividends are declared daily and paid monthly. Dividends are automatically
reinvested on payment dates in additional shares of the Fund unless cash
payments are requested by writing to the Fund. Shares purchased by wire
before 5:00 p.m. (Eastern time) begin earning dividends that day. Shares
purchased by check begin earning dividends the day after the check is
converted into federal funds.

CAPITAL GAINS

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 will distribute in cash or additional shares any
realized net long-term capital gains at least once every 12 months.

CONFIRMATIONS AND ACCOUNT STATEMENTS

Shareholders will receive detailed confirmations of transactions (except for
systematic program transactions). In addition, shareholders will receive
periodic statements reporting all account activity, including dividends
paid. The Fund will not issue share certificates.

ACCOUNTS WITH LOW BALANCES

Due to the high cost of maintaining accounts with low balances, the Fund may
redeem shares in any account, except accounts maintained by retirement
plans, and pay the proceeds to the shareholder if the account balance falls
below a required minimum value of $1,000,000 due to shareholder redemptions.
Before shares are redeemed to close an account, the shareholder is notified
in writing and allowed 30 days to purchase additional shares to meet the
minimum requirement.

VOTING RIGHTS

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

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

                              TAX INFORMATION

FEDERAL INCOME TAX

The Fund will pay no federal income tax because it expects to meet
requirements of the Internal Revenue Code applicable to regulated investment
companies and to receive the special tax treatment afforded to such
companies. The Fund will be treated as a single, separate entity for federal
income tax purposes so that income (including capital gains) and losses
realized by the Trust's other portfolios will not be combined for tax
purposes with those realized by the Fund.

Unless otherwise exempt, shareholders are required to pay federal income tax
on any dividends and other distributions received. This applies whether
dividends and distributions are received in cash or as additional shares.

STATE AND LOCAL TAXES

In the opinion of Houston, Donnelly & Meck, counsel to the Trust, Fund
shares may be subject to personal property taxes imposed by counties,
municipalities, and school districts in Pennsylvania to the extent that the
portfolio securities in the Fund would be subject to such taxes if owned
directly by residents of those jurisdictions.

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

                          OTHER CLASSES OF SHARES

The Fund also offers other classes. Institutional Shares are sold at net
asset value primarily to financial institutions, financial intermediaries,
institutional investors, and entities holding shares in an agency or
fiduciary capacity, and are subject to a minimum initial investment of
$1,000,000.

All classes are subject to certain of the same expenses.

Institutional Shares are distributed with no 12b-1 Plan but are subject to
shareholder services fees.

Expense differences between classes may affect the performance of each
class.

To obtain more information and a prospectus for any other class, investors
may call 1-800-341-7400.

                          PERFORMANCE INFORMATION

From time to time, the Fund advertises its yield, effective yield and total
return. The performance figures will be calculated separately for each class
of shares.

Yield represents the annualized rate of income earned on an investment over
a seven-day period. It is the annualized dividends earned during the period
on an investment shown as a percentage of the investment. The effective
yield is calculated similarly to the yield, but when annualized, the income
earned by an investment is assumed to be reinvested daily. The effective
yield will be slightly higher than the yield because of the compounding
effect of this assumed reinvestment.

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

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

                       NOTES TO FINANCIAL STATEMENTS
                         GOVERNMENT OBLIGATIONS FUND

                               JULY 31, 1997

ORGANIZATION

Money Market Obligations Trust (the "Trust") is registered under the
Investment Company Act of 1940, as amended (the "Act") as an open-end,
management investment company. The Trust consists of six portfolios. The
financial statements included herein are only those of Government
Obligations Fund (the "Fund"). The financial statements of the other
portfolios are presented separately. The assets of each portfolio are
segregated and a shareholder's interest is limited to the portfolio in which
shares are held. The investment objective of the Fund is to provide current
income consistent with stability of principal.

The Fund offers two classes of shares: Institutional Shares and
Institutional Service Shares.

SIGNIFICANT ACCOUNTING POLICIES

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

INVESTMENT VALUATIONS

The Fund uses the amortized cost method to value its portfolio securities in
accordance with Rule 2a-7 under the Act.

REPURCHASE AGREEMENTS

It is the policy of the Fund to require the custodian bank to take
possession, to have legally segregated in the Federal Reserve Book Entry
System, or to have segregated within the custodian bank's vault, all
securities held as collateral under repurchase agreement transactions.
Additionally, procedures have been established by the Fund to monitor, on a
daily basis, the market value of each repurchase agreement's collateral to
ensure that the value of collateral at least equals the repurchase price to
be paid under the repurchase agreement transaction.

The Fund will only enter into repurchase agreements with banks and other
recognized financial institutions, such as broker/
dealers, which are deemed by the Fund's adviser to be creditworthy pursuant
to the guidelines and/or standards reviewed or established by the Board of
Trustees (the "Trustees"). Risks may arise from the potential inability of
counterparties to honor the terms of the repurchase agreement. Accordingly,
the Fund could receive less than the repurchase price on the sale of
collateral securities.

INVESTMENT INCOME, EXPENSES AND DISTRIBUTIONS

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

FEDERAL TAXES

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

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

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

USE OF ESTIMATES

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

OTHER

Investment transactions are accounted for on the trade date.

SHARES OF BENEFICIAL INTEREST

The Declaration of Trust permits the Trustees to issue an unlimited number
of full and fractional shares of beneficial interest (without par value) for
each class of shares. At July 31, 1997, capital paid-in aggregated
$4,230,260,373. Transactions in shares were as follows:

                  REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Shareholders and Board of Trustees of
MONEY MARKET OBLIGATIONS TRUST
(Government Obligations Fund):

We have audited the accompanying statement of assets and liabilities of
Government Obligations Fund (an investment portfolio of Money Market
Obligations Trust, a Massachusetts business trust), including the schedule
of portfolio investments, as of July 31, 1997, the related statement of
operations for the year then ended, the statement of changes in net assets
for each of the two years in the period then ended, and the financial
highlights for the periods presented. These financial statements and
financial highlights are the responsibility of the Trust's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements and
financial highlights are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures
in the financial statements. Our procedures included confirmation of
securities owned as of July 31, 1997, by correspondence with the custodian
and brokers. An audit also includes assessing the accounting principles used
and significant estimates made by management, as well as evaluating the
overall financial statement presentation. We believe that our audits provide
a reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of
Government Obligations Fund (an investment portfolio of Money Market
Obligations Trust) as of July 31, 1997, the results of its operations for
the year then ended, the changes in its net assets for each of the two years
in the period then ended, and its financial highlights for the periods
presented, in conformity with generally accepted accounting principles.

INVESTMENT POLICIES

Unless indicated otherwise, the policies described below may be changed by
the Board of Trustees (the "Trustees") without shareholder approval.
Shareholders will be notified before any material change in these policies
becomes effective.

ACCEPTABLE INVESTMENTS

Some of the short-term U.S. government securities the Fund may purchase
carry variable interest rates. These securities have a rate of interest
subject to adjustment at least annually. This adjusted interest rate
ordinarily is tied to some objective standard, such as the 91-day U.S.
Treasury bill rate. Variable interest rates will reduce the changes in the
market value of such securities from their original purchase prices.
Accordingly, the potential for capital appreciation or capital depreciation
should not be greater than that of fixed-interest-rate U.S. government
securities having maturities equal to the interest rate adjustment dates of
the variable-rate U.S. government securities. The Fund may purchase
variable-rate U.S. government securities upon the determination by the
Trustees that the interest rate as adjusted will cause the instrument to
have a current market value that approximates its par value on the
adjustment date.

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

These transactions are made to secure what is considered to be an
advantageous price or yield for the Fund. No fees or other expenses, other
than normal transaction costs, are incurred. However, liquid assets of the
Fund in a dollar amount sufficient to make payment for the securities to be
purchased are: segregated on the Fund's records at the trade date; marked to
market daily; and maintained until the transaction is settled. The Fund does
not intend to engage in when-issued and delayed delivery transactions to an
extent that would cause the segregation of more than 20% of the total value
of its assets.

REPURCHASE AGREEMENTS

The Fund believes that under the regular procedures normally in effect for
custody of the Fund's portfolio securities subject to repurchase agreements,
a court of competent jurisdiction would rule in favor of the Fund and allow
retention or disposition of such securities. The Fund will only enter into
repurchase agreements with banks and other recognized financial
institutions, such as broker/dealers, which are deemed by the Fund's adviser
to be creditworthy pursuant to guidelines established by the Trustees.

REVERSE REPURCHASE AGREEMENTS

The Fund may also enter into reverse repurchase agreements. These
transactions are similar to borrowing cash. In a reverse repurchase
agreement, the Fund transfers possession of a portfolio instrument in return
for a percentage of the instrument's market value in cash and agrees that on
a stipulated date in the future the Fund will repurchase the portfolio
instrument by remitting the original consideration plus interest at an
agreed-upon rate. The use of reverse repurchase agreements may enable the
Fund to avoid selling portfolio instruments at a time when a sale may be
deemed to be disadvantageous, but does not ensure this result. However,
liquid assets of the Fund, in a dollar amount sufficient to make payment for
the securities to be purchased, are: segregated on the Fund's records at the
trade date; marked to market daily; and maintained until the transaction is
settled.

LENDING OF PORTFOLIO SECURITIES

The collateral received when the Fund lends portfolio securities must be
valued daily and, should the market value of the loaned securities increase,
the borrower must furnish additional collateral to the Fund. During the time
portfolio securities are on loan, the borrower pays the Fund any dividends
or interest paid on such securities. Loans are subject to termination at the
option of the Fund or the borrower. The Fund may pay reasonable
administrative and custodial fees in connection with a loan and may pay a
negotiated portion of the interest earned on the cash or equivalent
collateral to the borrower or placing broker.

INVESTMENT LIMITATIONS

SELLING SHORT AND BUYING ON MARGIN

The Fund will not sell any securities short or purchase any securities on
margin but may obtain such short-term credits as are necessary for clearance
of transactions.

ISSUING SENIOR SECURITIES AND BORROWING MONEY

The Fund will not issue senior securities except that the Fund may borrow
money directly or through reverse repurchase agreements in amounts up to
one-third of the value of its total assets, including the amounts borrowed.

The Fund will not borrow money or engage in reverse repurchase agreements
for investment leverage, but rather as a temporary, extraordinary, or
emergency measure or to facilitate management of the portfolio by enabling
the Fund to meet redemption requests when the liquidation of portfolio
securities is deemed to be inconvenient or disadvantageous. The Fund will
not purchase any securities while borrowings in excess of 5% of the value of
its total assets are outstanding. During the period any reverse repurchase
agreements are outstanding, the Fund will restrict the purchase of portfolio
securities to money market instruments maturing on or before the expiration
date of the reverse repurchase agreements, but only to the extent necessary
to assure completion of the reverse repurchase agreements.

PLEDGING ASSETS

The Fund will not mortgage, pledge, or hypothecate any assets except to
secure permitted borrowings. In those cases, it may pledge assets having a
market value not exceeding the lesser of the dollar amounts borrowed or 15%
of the value of total assets of the Fund at the time of the pledge.

LENDING CASH OR SECURITIES

The Fund will not lend any of its assets, except portfolio securities. This
shall not prevent the Fund from purchasing or holding bonds, debentures,
notes, certificates of indebtedness or other debt securities, entering into
repurchase agreements or engaging in other transactions where permitted by
its investment objective, policies, and limitations or the Trust's
Declaration of Trust.

INVESTING IN COMMODITIES

The Fund will not purchase or sell commodities, commodity contracts, or
commodity futures contracts.

INVESTING IN REAL ESTATE

The Fund will not purchase or sell real estate, including limited
partnership interests although it may invest in securities of issuers whose
business involves the purchase or sale of real estate or in securities which
are secured by real estate or interests in real estate.

UNDERWRITING

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

CONCENTRATION OF INVESTMENTS

The Fund will not invest 25% or more of the value of its total assets in any
one industry. However, the Fund may invest 25% or more of the value of its
total assets in cash, cash items, or 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. The
U.S. government is not considered to be an industry.

DIVERSIFICATION OF INVESTMENTS

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, or 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) if as a result more than
5% of the value of its total assets would be invested in the securities of
that issuer, or if it would own more than 10% of the outstanding voting
securities of that issuer.

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

INVESTING IN ILLIQUID SECURITIES

The Fund will not invest more than 10% of the value of its net assets in
illiquid securities including repurchase agreements providing for settlement
in more than seven days after notice.

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.

INVESTING FOR CONTROL

The Fund will not invest in securities of a company for the purpose of
exercising control or management.

INVESTING IN OPTIONS

The Fund will not invest in puts, calls, straddles, spreads, or any
combination of them.

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.

The Fund did not borrow money or pledge securities in excess of 5% of the
value of its net assets during the last fiscal year and has no present
intent to do so during the coming fiscal year.

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, which regulates
money market mutual funds. The Fund will determine the effective maturity of
its investments according to Rule 2a-7. The Fund may change these
operational policies to reflect changes in the laws and regulations without
the approval of its shareholders.

TRUSTEE LIABILITY

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

INVESTMENT ADVISORY SERVICES

INVESTMENT ADVISER

The Fund's investment adviser is Federated Management. It is a subsidiary of
Federated Investors. All the voting securities of Federated Investors are
owned by a trust, the trustees of which are John F. Donahue, his wife and
his son, J. Christopher Donahue.

The adviser shall not be liable to the Trust, the Fund, or any shareholder
of the Fund for any losses that may be sustained in the purchase, holding,
or sale of any security or for anything done or omitted by it, except acts
or omissions involving willful misfeasance, bad faith, gross negligence, or
reckless disregard of the duties imposed upon it by its contract with the
Fund.

ADVISORY FEES

For its advisory services, Federated Management receives an annual
investment advisory fee as described in the prospectus. For the fiscal years
ended July 31, 1997, 1996, and 1995, the adviser earned $6,777,523,
$5,061,781, and $2,842,786, respectively, of which $3,522,148, $2,827,496,
and $2,063,842, respectively, were waived.

BROKERAGE TRANSACTIONS

When selecting brokers and dealers to handle the purchase and sale of
portfolio instruments, the adviser looks for prompt execution of the order
at a favorable price. In working with dealers, the adviser will generally
use those who are recognized dealers in specific portfolio instruments,
except when a better price and execution of the order can be obtained
elsewhere. The adviser makes decisions on portfolio transactions and selects
brokers and dealers subject to guidelines established by the Trustees. The
adviser may select brokers and dealers who offer brokerage and research
services. These services may be furnished directly to the Fund or to the
adviser and may include: advice as to the advisability of investing in
securities; security analysis and reports; economic studies; industry
studies; receipt of quotations for portfolio evaluations; and similar
services. Research services provided by brokers and dealers may be used by
the adviser or its affiliates in advising the Fund and other accounts. To
the extent that receipt of these services may supplant services for which
the adviser or its affiliates might otherwise have paid, it would tend to
reduce their expenses. The adviser and its affiliates exercise reasonable
business judgment in selecting brokers who offer brokerage and research
services to execute securities transactions. They determine in good faith
that commissions charged by such persons are reasonable in relationship to
the value of the brokerage and research services provided. During the fiscal
years ended July 31, 1997, 1996, and 1995, the Fund paid no brokerage
commissions.

Although investment decisions for the Fund are made independently from those
of the other accounts managed by the adviser, investments of the type the
Fund may make may also be made by those other accounts. When the Fund and
one or more other accounts managed by the adviser are prepared to invest in,
or desire to dispose of, the same security, available investments or
opportunities for sales will be allocated in a manner believed by the
adviser to be equitable to each. In some cases, this procedure may adversely
affect the price paid or received by the Fund or the size of the position
obtained or disposed of by the Fund. In other cases, however, it is believed
that coordination and the ability to participate in volume transactions will
be to the benefit of the Fund.

OTHER SERVICES

FUND ADMINISTRATION

Federated Services Company, a subsidiary of Federated Investors, provides
administrative personnel and services to the Fund for a fee as described in
the prospectus. From March 1, 1994 to March 1, 1996, Federated
Administrative Services, a subsidiary of Federated Investors, served as the
Fund's Administrator. For purposes of this Statement of Additional
Information, Federated Services Company and Federated Administrative
Services may hereinafter collectively be referred to as the
"Administrators." For the fiscal years ended July 31, 1997, 1996, and 1995,
the Administrators earned $2,559,413, $1,914,143, and $1,075,995,
respectively.

CUSTODIAN AND PORTFOLIO ACCOUNTANT

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

TRANSFER AGENT

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

INDEPENDENT PUBLIC ACCOUNTANTS

The independent public accountants for the Fund are Arthur Andersen LLP,
Pittsburgh, Pennsylvania.

SHAREHOLDER SERVICES

This arrangement permits the payment of fees to Federated Shareholder
Services to cause services to be provided which are necessary for the
maintenance of shareholder accounts and to encourage personal services to
shareholders by a representative who has knowledge of the shareholder's
particular circumstances and goals. These activities and services may
include but are not limited to providing office space, equipment, telephone
facilities, and various clerical, supervisory, computer, and other personnel
as necessary or beneficial to establish and maintain shareholder accounts
and records; processing purchase and redemption transactions and automatic
investments of client account cash balances; answering routine client
inquiries; and assisting clients in changing dividend options, account
designations, and addresses.

By adopting the Shareholder Services Agreement, the Trustees expect that the
Fund will benefit by: (1) providing personal services to shareholders; (2)
investing shareholder assets with a minimum of delay and administrative
detail; (3) enhancing shareholder recordkeeping systems; and (4) responding
promptly to shareholders' requests and inquiries concerning their accounts.

For the fiscal year ended July 31, 1997, the Fund earned shareholder service
fees on behalf of Institutional Shares and Institutional Service Shares in
the amounts of $6,307,126 and $2,164,778, respectively, $0 and $2,164,778 of
which, respectively, was paid to financial institutions.

DETERMINING NET ASSET VALUE

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 Rule 2a-7 (the "Rule")
promulgated by the Securities and Exchange Commission under the Investment
Company Act of 1940. 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.

REDEMPTION IN KIND

The Fund is obligated to redeem shares solely in cash up to $250,000 or 1%
of the Fund's net asset value, whichever is less, for any one shareholder
within a 90-day period. Any redemption beyond this amount will also be in
cash unless the Trustees determine that further payments should be in kind.
In such cases, the Fund will pay all or a portion of the remainder of the
redemption in portfolio instruments valued in the same way as the Fund
determines net asset value. The portfolio instruments will be selected in a
manner that the Trustees deem fair and equitable. Redemption in kind is not
as liquid as a cash redemption. If redemption is made in kind, shareholders
who sell these securities could receive less than the redemption value and
could incur certain transaction costs.

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. These documents require notice of this disclaimer
to be given in each agreement, obligation, or instrument the Trust or its
Trustees enter into or sign.

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.

THE FUND'S TAX STATUS

To qualify for the special tax treatment afforded to regulated investment
companies, the Fund must, among other requirements: derive at least 90% of
its gross income from dividends, interest, and gains from the sale of
securities; derive less than 30% of its gross income from the sale of
securities held less than three months; invest in securities within certain
statutory limits; and distribute to its shareholders at least 90% of its net
income earned during the year.

PERFORMANCE INFORMATION

Performance depends upon such variables as: portfolio quality; average
portfolio maturity; type of instruments in which the portfolio is invested;
changes in interest rates; changes in expenses; and the relative amount of
cash flow. To the extent that financial institutions and broker/dealers
charge fees in connection with services provided in conjunction with an
investment in shares of the Fund, the performance will be reduced for those
shareholders paying those fees.

YIELD

The yield is calculated based upon the seven days ending on the day of the
calculation, called the "base period." This yield is computed 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.

For the seven-day period ended July 31, 1997, the yield for Institutional
Shares was 5.50%, and the yield for Institutional Service Shares was 5.25%.


EFFECTIVE YIELD

The effective yield is calculated by compounding the unannualized base
period return by: adding 1 to the base period return; raising the sum to the
365/7th power; and subtracting 1 from the result.

For the seven-day period ended July 31, 1997, the effective yield for
Institutional Shares was 5.65%, and the effective yield for Institutional
Service Shares was 5.38%


TOTAL RETURN

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

For the one-year and five-year periods ended July 31, 1997, and for the
period from March 31, 1990 (date of initial public investment) through July
31, 1997, the average annual total returns were 5.43%, 4.63% and 5.16%,
respectively, for Institutional Shares. For the one-year period ended July
31, 1997, and for the period from August 1, 1994 (date of initial public
investment) to July 31, 1997, the average annual total returns were 5.16%
and 5.23%, respectively, for Institutional Service Shares.

</TABLE>

(1) The management fee has been reduced to reflect the voluntary waiver of a
    portion of the management fee. The adviser can terminate this voluntary
    waiver at any time at its sole discretion. The maximum management fee is
    0.20%.

    waiver of the shareholder services fee. The shareholder service provider
    can terminate this voluntary waiver at any time at its sole discretion. The
    maximum shareholder services fee is 0.25%

(3) The total operating expenses would have been 0.56% absent the voluntary
    waiver of a portion of the management fee and the shareholder services fee.

The purpose of this table is to assist an investor in understanding the
various costs and expenses that a shareholder of Institutional Shares of the
Fund will bear, either directly or indirectly. For more complete
descriptions of the various costs and expenses, see "Fund Information" and
"How to Purchase Shares." Wire-transferred redemptions of less than $5,000

                            GENERAL INFORMATION

The Trust was established as a Massachusetts business trust under a
Declaration of Trust dated October 3, 1988. The Declaration of Trust permits
the Trust to offer separate series of shares representing interests in
separate portfolios of securities. The shares in any one portfolio may be
offered in separate classes. With respect to this Fund, as of the date of
this prospectus, the Board of Trustees (the "Trustees") has established two
classes of shares known as Institutional Shares and Institutional Service
Shares. This prospectus relates only to Institutional Shares of the Fund,
which are designed primarily for entities holding shares in an agency or
fiduciary capacity, financial institutions, financial intermediaries and
institutional investors as a convenient means of accumulating an interest in
a professionally managed portfolio investing in short-term money market
securities. A minimum initial investment of $1,000,000 over a one-year
period is required.

The Fund attempts to stabilize the value of a share at $1.00. Shares are
currently sold and redeemed at that price.

                           INVESTMENT INFORMATION

INVESTMENT OBJECTIVE

The investment objective of the Fund is to provide current income consistent
with stability of principal. This investment objective cannot be changed
without shareholder approval. While there is no assurance that the Fund will
achieve its investment objective, it endeavors to do so by complying with
the diversification and other requirements of Rule 2a-7 under the Investment
Company Act of 1940 which regulates money market mutual funds and by
following the investment policies described in this prospectus.

INVESTMENT POLICIES

The Fund pursues its investment objective by investing in a portfolio of
money market securities maturing in 13 months or less. The average maturity
of the securities in the Fund's portfolio, computed on a dollar-weighted
basis, will be 90 days or less. Unless indicated otherwise, the investment
policies may be changed by the Trustees without shareholder approval.
Shareholders will be notified before any material change in these policies
becomes effective.

ACCEPTABLE INVESTMENTS

The Fund invests in high quality money market instruments that are either
rated in the highest short-term rating category by one or more nationally
recognized statistical rating organizations ("NRSROs") or are of comparable
quality to securities having such ratings. Examples of these instruments
include, but are not limited to:

* domestic issues of corporate debt obligations, including variable rate
  demand notes;

* commercial paper (including Canadian Commercial Paper and Europaper);

* certificates of deposit, demand and time deposits, bankers' acceptances
  and other instruments of domestic and foreign banks and other deposit
  institutions ("Bank Instruments");

* short-term credit facilities;

* asset-backed securities;

* obligations issued or guaranteed as to payment of principal and interest
  by the U.S. government or one of its agencies or instrumentalities; and

* other money market instruments.

The Fund invests only in instruments denominated and payable in U.S.
dollars.

VARIABLE RATE DEMAND NOTES

  Variable rate demand notes are long-term debt instruments that have variable
  or floating interest rates and provide the Fund with the right to tender the
  security for repurchase at its stated principal amount plus accrued
  interest. Such securities typically bear interest at a rate that is intended
  to cause the securities to trade at par. The interest rate may float or be
  adjusted at regular intervals (ranging from daily to annually), and is
  normally based on a published interest rate or interest rate index. Most
  variable rate demand notes allow the Fund to demand the repurchase of the
  security on not more than seven days prior notice. Other notes only permit
  the Fund to tender the security at the time of each interest rate adjustment
  or at other fixed intervals. See "Demand Features." The Fund treats variable
  rate demand notes as maturing on the later of the date of the next interest
  rate adjustment or the date on which the Fund may next tender the security
  for repurchase.
 
  BANK INSTRUMENTS
 
  The Fund only invests in Bank Instruments either issued by an institution
  having capital, surplus and undivided profits over $100 million, or insured
  by the Bank Insurance Fund ("BIF") or the Savings Association Insurance Fund
  ("SAIF"). Bank Instruments may include Eurodollar Certificates of Deposit
  ("ECDs"), Yankee Certificates of Deposit ("Yankee CDs") and Eurodollar Time
  Deposits ("ETDs"). The Fund will treat securities credit enhanced with a
  bank's letter of credit as Bank Instruments.
 
  ASSET-BACKED SECURITIES
 
  Asset-backed securities are securities issued by special purpose entities
  whose primary assets consist of a pool of loans or accounts receivable. The
  securities may take the form of beneficial interests in special purpose
  trusts, limited partnership interests, or commercial paper or other debt
  securities issued by a special purpose corporation. Although the securities
  often have some form of credit or liquidity enhancement, payments on the
  securities depend predominantly upon collections of the loans and
  receivables held by the issuer.
 
  SHORT-TERM CREDIT FACILITIES
 
  The Fund may enter into, or acquire participations in, short-term borrowing
  arrangements with corporations, consisting of either a short-term revolving
  credit facility or a master note agreement payable upon demand. Under these
  arrangements, the borrower may reborrow funds during the term of the
  facility. The Fund treats any commitments to provide such advances as a
  standby commitment to purchase the borrower's notes.
 
REPURCHASE AGREEMENTS

Certain securities in which the Fund invests may be purchased pursuant to
repurchase agreements. Repurchase agreements are arrangements in which
banks, broker/dealers, and other recognized financial institutions sell
securities to the Fund and agree at the time of sale to repurchase them at a
mutually agreed upon time and price. To the extent that the seller does not
repurchase the securities from the Fund, the Fund could receive less than
the repurchase price on any sale of such securities.

CREDIT ENHANCEMENT

Certain of the Fund's acceptable investments may be credit-enhanced by a
guaranty, letter of credit, or insurance. Any bankruptcy, receivership,
default, or change in the credit quality of the party providing the credit
enhancement will adversely affect the quality and marketability of the
underlying security and could cause losses to the Fund and affect its share
price.

DEMAND FEATURES

The Fund may acquire securities that are subject to puts and standby
commitments ("demand features") to purchase the securities at their
principal amount (usually with accrued interest) within a fixed period
(usually seven days) following a demand by the Fund. The demand feature may
be issued by the issuer of the underlying securities, a dealer in the
securities, or by another third party, and may not be transferred separately
from the underlying security. The Fund uses these arrangements to provide
the Fund with liquidity and not to protect against changes in the market
value of the underlying securities. The bankruptcy, receivership, or default
by the issuer of the demand feature, or a default on the underlying security
or other event that terminates the demand feature before its exercise, will
adversely affect the liquidity of the underlying security. Demand features
that are exercisable even after a payment default on the underlying security
may be treated as a form of credit enhancement.

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

The Fund may purchase securities on a when-issued or delayed delivery basis.
These transactions are arrangements in which the Fund purchases securities
with payment and delivery scheduled for a future time. The seller's failure
to complete these transactions may cause the Fund to miss a price or yield
considered to be advantageous. Settlement dates may be a month or more after
entering into these transactions, and the market values of the securities
purchased may vary from the purchase prices.

The Fund may dispose of a commitment prior to settlement if the adviser
deems it appropriate to do so. In addition, the Fund may enter into
transactions to sell its purchase commitments to third parties at current
market values and simultaneously acquire other commitments to purchase
similar securities at later dates. The Fund may realize short-term profits
or losses upon the sale of such commitments.

LENDING OF PORTFOLIO SECURITIES

In order to generate additional income, the Fund may lend its portfolio
securities on a short-term or long-term basis, or both, to broker/dealers,
banks, or other institutional borrowers of securities. The Fund will only
enter into loan arrangements with broker/dealers, banks, or other
institutions which the adviser has determined are creditworthy under
guidelines established by the Fund's Trustees and will receive collateral at
all times equal to at least 100% of the value of the securities loaned.
There is the risk that when lending portfolio securities, the securities may
not be available to the Fund on a timely basis and the Fund may, therefore,
lose the opportunity to sell the securities at a desirable price. In
addition, in the event that a borrower of securities would file for
bankruptcy or become insolvent, disposition of the securities may be delayed
pending court action.

RESTRICTED AND ILLIQUID SECURITIES
 
The Fund may invest in restricted securities, and, as a matter of
fundamental investment policy which cannot be changed without shareholder
approval, will limit such investments to 10% of its net assets. This
restriction is not applicable to commercial paper issued under Section 4(2)
of the Securities Act of 1933. Restricted securities are any securities in
which the Fund may invest pursuant to its investment objective and policies
but which are subject to restrictions on resale under federal securities
law. Under criteria established by the Trustees, certain restricted
securities are determined to be liquid. As a matter of non-fundamental
investment policy, to the extent that restricted securities are not
determined to be liquid, the Fund will limit their purchase, together with
other illiquid securities, including non-negotiable time deposits, and
repurchase agreements providing for settlement in more than seven days after
notice, to 10% of its net assets.

CONCENTRATION OF INVESTMENTS

As a matter of policy which cannot be changed without shareholder approval,
the Fund will generally invest 25% or more of its total assets in commercial
paper issued by finance companies. The finance companies in which the Fund
intends to invest can be divided into two categories, commercial finance
companies and consumer finance companies. Commercial finance companies are
principally engaged in lending to corporations or other businesses. Consumer
finance companies are primarily engaged in lending to individuals. Captive
finance companies or finance subsidiaries which exist to facilitate the
marketing and financial activities of their parent will, for purposes of
industry concentration, be classified in the industry of their parent's
corporation. In addition, the Fund may invest 25% or more of the value of
its total assets in instruments issued by a U.S. branch of a domestic bank
or savings association having capital, surplus, and undivided profits in
excess of $100,000,000 at the time of investment. Concentrating investments
in one industry may subject the Fund to more risk than if it did not
concentrate.

INVESTMENT RISKS

ECDs, ETDs, Yankee CDs, Canadian Commercial Paper, and Europaper are subject
to different risks than domestic obligations of domestic banks or
corporations. Examples of these risks include international economic and
political developments, foreign governmental restrictions that may adversely
affect the payment of principal or interest, foreign withholding or other
taxes on interest income, difficulties in obtaining or enforcing a judgment
against the issuing entity, and the possible impact of interruptions in the
flow of international currency transactions. Risks may also exist for ECDs,
ETDs, and Yankee CDs because the banks issuing these instruments, or their
domestic or foreign branches, are not necessarily subject to the same
regulatory requirements that apply to domestic banks, such as reserve
requirements, loan limitations, examinations, accounting, auditing,
recordkeeping, and the public availability of information. These factors
will be carefully considered by the Fund's adviser in selecting investments
for the Fund.

INVESTMENT LIMITATIONS

The Fund will not borrow money directly or through reverse repurchase
agreements (arrangements in which the Fund sells a money market instrument
for a percentage of its cash value with an agreement to buy it back on a set
date) or pledge securities except, under certain circumstances, the Fund may
borrow up to one-third of the value of its total assets and pledge up to 15%
of the value of those assets to secure such borrowings. These investment
limitations cannot be changed without shareholder approval.

                              FUND INFORMATION

MANAGEMENT OF THE FUND

BOARD OF TRUSTEES

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

INVESTMENT ADVISER

Investment decisions for the Fund are made by Federated Management, the
Fund's investment adviser, subject to direction by the Trustees. The adviser
continually conducts investment research and supervision for the Fund and is
responsible for the purchase and sale of portfolio instruments.

  ADVISORY FEES
 
  The adviser receives an annual investment advisory fee equal to 0.20% of the
  Fund's average daily net assets. The adviser may voluntarily choose to waive
  a portion of its fee or reimburse other expenses of the Fund, but reserves
  the right to terminate such waiver or reimbursement at any time at its sole
  discretion.
 
  ADVISER'S BACKGROUND
 
  Federated Management, a Delaware business trust, organized on April 11,
  1989, is a registered investment adviser under the Investment Advisers Act
  of 1940. It is a subsidiary of Federated Investors. All of the Class A
  (voting) shares of Federated Investors are owned by a trust, the trustees of
  which are John F. Donahue, Chairman and Trustee of Federated Investors, Mr.
  Donahue's wife, and Mr. Donahue's son, J. Christopher Donahue, who is
  President and Trustee of Federated Investors.
 
  Federated Management and other subsidiaries of Federated Investors serve as
  investment advisers to a number of investment companies and private
  accounts. Certain other subsidiaries also provide administrative services to
  a number of investment companies. With over $110 billion invested across
  over 300 funds under management and/or administration by its subsidiaries,
  as of December 31, 1996, Federated Investors is one of the largest mutual
  fund investment managers in the United States. With more than 2,000
  employees, Federated continues to be led by the management who founded the
  company in 1955. Federated funds are presently at work in and through 4,500
  financial institutions nationwide.
 
Both the Trust and the adviser have adopted strict codes of ethics governing
the conduct of all employees who manage the Fund and its portfolio
securities. These codes recognize that such persons owe a fiduciary duty to
the Fund's shareholders and must place the interests of shareholders ahead
of the employees' own interests. Among other things, the codes: require
preclearance and periodic reporting of personal securities transactions;
prohibit personal transactions in securities being purchased or sold, or
being considered for purchase or sale, by the Fund; prohibit purchasing
securities in initial public offerings; and prohibit taking profits on
securities held for less than sixty days. Violations of the codes are
subject to review by the Trustees, and could result in severe penalties.

DISTRIBUTION OF INSTITUTIONAL SHARES

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

SHAREHOLDER SERVICES

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

SUPPLEMENTAL PAYMENTS TO FINANCIAL INSTITUTIONS

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

ADMINISTRATION OF THE FUND

ADMINISTRATIVE SERVICES

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

MAXIMUM             AVERAGE AGGREGATE
  FEE               DAILY NET ASSETS

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

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

                              NET ASSET VALUE

The Fund attempts to stabilize the net asset value of shares at $1.00 by
valuing the portfolio securities using the amortized cost method. The net
asset value per share is determined by subtracting liabilities attributable
to Institutional Shares from the value of Fund assets attributable to
Institutional Shares, and dividing the remainder by the number of
Institutional Shares outstanding. The Fund cannot guarantee that its net
asset value will always remain at $1.00 per share.

The net asset value is determined at 5:00 p.m. (Eastern time) Monday through
Friday, except on New Year's Day, Martin Luther King Day, Presidents' Day,
Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day,
and Christmas Day.

                           HOW TO PURCHASE SHARES

Shares are sold at their net asset value, without a sales charge, next
determined after an order is received, on days on which the New York Stock
Exchange is open for business. Shares may be purchased either by wire or by
check. The Fund reserves the right to reject any purchase request.

To make a purchase, open an account by calling Federated Securities Corp.
Information needed to establish the account will be taken by telephone. The
minimum initial investment is $1,000,000. However, an account may be opened
with a smaller amount as long as the minimum is reached within one year of
opening the account. Financial institutions may impose different minimum
investment requirements on their customers.

PURCHASING SHARES BY WIRE

Shares may be purchased by Federal Reserve wire by calling the Fund before
5:00 p.m. (Eastern time) to place an order. The order is considered received
immediately. Payment by federal funds must be received before 5:00 p.m.
(Eastern time) that day. Federal funds should be wired as follows: Federated
Shareholder Services Company, c/o State Street Bank and Trust Company,
Boston, MA; Attention: EDGEWIRE; For Credit to: Prime Obligations Fund --
Institutional Shares; Fund Number (this number can be found on the account
statement or by contacting the Fund); Group Number or Order Number; Nominee
or Institution Name; and ABA Number 011000028. Shares cannot be purchased by
wire on holidays when wire transfers are restricted. Questions on wire
purchases should be directed to your shareholder services representative at
the telephone number listed on your account statement.

PURCHASING SHARES BY CHECK

Shares may be purchased by sending a check to Federated Shareholder Services
Company, P.O. Box 8600, Boston, MA 02266-8600. The check should be made
payable to: Prime Obligations Fund -- Institutional Shares. 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.

INVEST-BY-PHONE

Once an account has been opened, a shareholder may use invest-by-phone for
investments if an authorization form has been filed with Federated
Shareholder Services Company, the transfer agent for shares of the Fund.
Approximately two weeks after sending the form to Federated Shareholder
Services Company, the shareholder may call Federated Shareholder Services
Company to purchase shares. Federated Shareholder Services Company will send
a request for monies to the shareholder's commercial bank, savings bank, or
credit union ("bank") via the Automated Clearing House. The shareholder's
bank, which must be an Automated Clearing House member, will then forward
the monies to Federated Shareholder Services Company. The purchase is
normally entered the next business day after the initial phone request. For
further information and an application, call the Fund.

                            HOW TO REDEEM SHARES

Shares are redeemed at their net asset value next determined after Federated
Shareholder Services Company receives the redemption request. Redemptions
will be made on days on which the Fund computes its net asset value.
Redemption requests must be received in proper form and can be made as
described below.

REDEEMING SHARES BY TELEPHONE

Redemptions in any amount may be made by calling the Fund provided the Fund
has a properly completed authorization form. These forms can be obtained
from Federated Securities Corp. Proceeds from redemption requests received
before 5:00 p.m. (Eastern time) will be wired the same day to the
shareholder's account at a domestic commercial bank which is a member of the
Federal Reserve System, but will not include that day's dividend. Proceeds
from redemption requests on holidays when wire transfers are restricted will
be wired the following business day. Questions about telephone redemptions
on days when wire transfers are restricted should be directed to your
shareholder services representative at the telephone number listed on your
account statement.

Telephone instructions may be recorded and if reasonable procedures are not
followed by the Fund, it may be liable for losses due to unauthorized or
fraudulent telephone instructions.

In the event of drastic economic or market changes, a shareholder may
experience difficulty in redeeming by telephone. If this occurs, "Redeeming
Shares by Mail" should be considered. If at any time the Fund shall
determine it necessary to terminate or modify the telephone redemption
privilege, shareholders would be promptly notified.

REDEEMING SHARES BY MAIL

Shares may be redeemed in any amount by mailing a written request to:
Federated Shareholder Services Company, P.O. Box 8600, Boston, MA
02266-8600. If share certificates have been issued, they should be sent
unendorsed with the written request by registered or certified mail to the
address noted above.

The written request should state: the Fund name and the class designation;
the account name as registered with the Fund; the account number; and the
number of shares to be redeemed or the dollar amount requested. All owners
of the account must sign the request exactly as the shares are registered.
Normally, a check for the proceeds is mailed within one business day, but in
no event more than seven days, after the receipt of a proper written
redemption request. Dividends are paid up to and including the day that a
redemption request is processed.

Shareholders requesting a redemption of any amount to be sent to an address
other than that on record with the Fund or a redemption payable other than
to the shareholder of record must have their signatures guaranteed by a
commercial or savings bank, trust company or savings association whose
deposits are insured by an organization which is administered by the Federal
Deposit Insurance Corporation; a member firm of a domestic stock exchange;
or any other "eligible guarantor institution," as defined in the Securities
Exchange Act of 1934. The Fund does not accept signatures guaranteed by a
notary public.

                       ACCOUNT AND SHARE INFORMATION

DIVIDENDS

Dividends are declared daily and paid monthly. Dividends are automatically
reinvested on payment dates in additional shares of the Fund unless cash
payments are requested by writing to the Fund. Shares purchased by wire
before 5:00 p.m. (Eastern time) begin earning dividends that day. Shares
purchased by check begin earning dividends the day after the check is
converted into federal funds.

CAPITAL GAINS

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 will distribute in cash or additional shares any
realized net long-term capital gains at least once every 12 months.

CONFIRMATIONS AND ACCOUNT STATEMENTS

Shareholders will receive detailed confirmations of transactions (except for
systematic program transactions). In addition, shareholders will receive
periodic statements reporting all activity, including dividends paid. The
Fund will not issue share certificates.

ACCOUNTS WITH LOW BALANCES

Due to the high cost of maintaining accounts with low balances, the Fund may
redeem shares in any account, except accounts maintained by retirement
plans, and pay the proceeds to the shareholder if the account balance falls
below a required minimum value of $1,000,000 due to shareholder redemptions.
Before shares are redeemed to close an account, the shareholder is notified
in writing and allowed 30 days to purchase additional shares to meet the
minimum requirement.

VOTING RIGHTS

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

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

                              TAX INFORMATION

FEDERAL INCOME TAX

The Fund will pay no federal income tax because it expects to meet
requirements of the Internal Revenue Code applicable to regulated investment
companies and to receive the special tax treatment afforded to such
companies. The Fund will be treated as a single, separate entity for federal
income tax purposes so that income (including capital gains) and losses
realized by the Trust's other portfolios will not be combined for tax
purposes with those realized by the Fund.

Unless otherwise exempt, shareholders are required to pay federal income tax
on any dividends and other distributions received. This applies whether
dividends and distributions are received in cash or as additional shares.

STATE AND LOCAL TAXES

In the opinion of Houston, Donnelly & Meck, counsel to the Trust, Fund
shares may be subject to personal property taxes imposed by counties,
municipalities, and school districts in Pennsylvania to the extent that the
portfolio securities in the Fund would be subject to such taxes if owned
directly by residents of those jurisdictions.

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

                          OTHER CLASSES OF SHARES

The Fund also offers other classes. Institutional Service Shares are sold at
net asset value primarily to financial institutions, financial
intermediaries and institutional investors and are subject to a minimum
initial investment of $1,000,000.

All classes are subject to certain of the same expenses.

Institutional Service Shares are distributed with no 12b-1 Plan but are
subject to shareholder services fees.

Expense differences between classes may affect the performance of each
class.

To obtain more information and a prospectus for any other class, investors
may call 1-800-341-7400.

                          PERFORMANCE INFORMATION

From time to time, the Fund advertises its yield, effective yield and total
return. The performance figures will be calculated separately for each class
of shares.

Yield represents the annualized rate of income earned on an investment over
a seven-day period. It is the annualized dividends earned during the period
on an investment shown as a percentage of the investment. The effective
yield is calculated similarly to the yield, but when annualized, the income
earned by an investment is assumed to be reinvested daily. The effective
yield will be slightly higher than the yield because of the compounding
effect of this assumed reinvestment.

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

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

                       NOTES TO FINANCIAL STATEMENTS

                           PRIME OBLIGATIONS FUND
                               JULY 31, 1997

ORGANIZATION

Money Market Obligations Trust (the "Trust") is registered under the
Investment Company Act of 1940, as amended (the "Act") as an open-end,
management investment company. The Trust consists of six portfolios. The
financial statements included herein are only those of Prime Obligations
Fund (the "Fund"), a diversified portfolio. The financial statements of the
other portfolios are presented separately. The assets of each portfolio are
segregated and a shareholder's interest is limited to the portfolio in which
shares are held. The investment objective of the Fund is to provide current
income consistent with stability of principal.

The Fund offers two classes of shares: Institutional Shares and
Institutional Service Shares.

SIGNIFICANT ACCOUNTING POLICIES

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

INVESTMENT VALUATIONS

The Fund uses the amortized cost method to value its portfolio securities in
accordance with Rule 2a-7 under the Act.

REPURCHASE AGREEMENTS

It is the policy of the Fund to require the custodian bank to take
possession, to have legally segregated in the Federal Reserve Book Entry
System, or to have segregated within the custodian bank's vault, all
securities held as collateral under repurchase agreement transactions.
Additionally, procedures have been established by the Fund to monitor, on a
daily basis, the market value of each repurchase agreement's collateral to
ensure that the value of collateral at least equals the repurchase price to
be paid under the repurchase agreement transaction.

The Fund will only enter into repurchase agreements with banks and other
recognized financial institutions, such as broker/dealers, which are deemed
by the Fund's adviser to be creditworthy pursuant to the guidelines and/or
standards reviewed or established by the Board of Trustees (the "Trustees").
Risks may arise from the potential inability of counterparties to honor the
terms of the repurchase agreement. Accordingly, the Fund could receive less
than the repurchase price on the sale of collateral securities.

INVESTMENT INCOME, EXPENSES AND DISTRIBUTIONS

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

FEDERAL TAXES

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

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

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

RESTRICTED SECURITIES

Restricted securities are securities that may only be resold upon
registration under federal securities laws or in transactions exempt from
such registration. Many restricted securities may be resold in the secondary
market in transactions exempt from registration. In some cases, the
restricted securities may be resold without registration upon exercise of a
demand feature. Such restricted securities may be determined to be liquid
under criteria established by the Trustees. The Fund will not incur any
registration costs upon such resales. Restricted securities are valued at
amortized cost in accordance with Rule 2a-7 under the Act.

Additional information on each restricted security held at July 31, 1997 is
as follows:

Travelers Insurance Company                  2/20/1997            44,000,000

USE OF ESTIMATES

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

OTHER

Investment transactions are accounted for on the trade date.

SHARES OF BENEFICIAL INTEREST

The Declaration of Trust permits the Trustees to issue an unlimited number
of full and fractional shares of beneficial interest (without par value) for
each class of shares. At July 31, 1997, capital paid-in aggregated
$5,825,079,379. Transactions in shares were as follows:

                  REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Shareholders of Board of Trustees of
MONEY MARKET OGLIBATIONS TRUST
(Prime Obligations Fund):

We have audited the accompanying statement of assets and liabilities of
Prime Obligations Fund (an investment portfolio of Money Market Obligations
Trust, a Massachusetts business trust), including the schedule of portfolio
investments, as of July 31, 1997, the related statement of operations for
the year then ended, the statement of changes in net assets for each of the
two years in the period then ended, and the financial highlights for the
periods presented. These financial statements and financial highlights are
the responsibility of the Trust's management. Our responsibility is to
express an opinion on these financial statements and financial highlights
based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements and
financial highlights are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures
in the financial statements. Our procedures included confirmation of
securities owned as of July 31, 1997, by correspondence with the custodian.
An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of
Prime Obligations Fund (an investment portfolio of Money Market Obligations
Trust) as of July 31, 1997, the results of its operations for the year then
ended, the changes in its net assets for each of the two years in the period

                            GENERAL INFORMATION

The Trust was established as a Massachusetts business trust under a
Declaration of Trust dated October 3, 1988. The Declaration of Trust permits
the Trust to offer separate series of shares representing interests in
separate portfolios of securities. The shares in any one portfolio may be
offered in separate classes. With respect to this Fund, as of the date of
this prospectus, the Board of Trustees (the "Trustees") has established two
classes of shares known as Institutional Service Shares and Institutional
Shares. This prospectus relates only to Institutional Service Shares of the
Fund, which are designed primarily for financial institutions, financial
intermediaries and institutional investors as a convenient means of
accumulating an interest in a professionally managed portfolio investing in
short-term money market securities. A minimum initial investment of
$1,000,000 over a one-year period is required.

The Fund attempts to stabilize the value of a share at $1.00. Shares are
currently sold and redeemed at that price.

                           INVESTMENT INFORMATION

INVESTMENT OBJECTIVE

The investment objective of the Fund is to provide current income consistent
with stability of principal. This investment objective cannot be changed
without shareholder approval. While there is no assurance that the Fund will
achieve its investment objective, it endeavors to do so by complying with
the diversification and other requirements of Rule 2a-7 under the Investment
Company Act of 1940 which regulates money market mutual funds and by
following the investment policies described in this prospectus.

INVESTMENT POLICIES

The Fund pursues its investment objective by investing in a portfolio of
money market securities maturing in 13 months or less. The average maturity
of the securities in the Fund's portfolio, computed on a dollar-weighted
basis, will be 90 days or less. Unless indicated otherwise, the investment
policies may be changed by the Trustees without shareholder approval.
Shareholders will be notified before any material change in these policies
becomes effective.

ACCEPTABLE INVESTMENTS

The Fund invests in high quality money market instruments that are either
rated in the highest short-term rating category by one or more nationally
recognized statistical rating organizations ("NRSROs") or are of comparable
quality to securities having such ratings. Examples of these instruments
include, but are not limited to:

* domestic issues of corporate debt obligations, including variable rate
  demand notes;

* commercial paper (including Canadian Commercial Paper and Europaper);

* certificates of deposit, demand and time deposits, bankers' acceptances
  and other instruments of domestic and foreign banks and other deposit
  institutions ("Bank Instruments");

* short-term credit facilities;

* asset-backed securities;

* obligations issued or guaranteed as to payment of principal and interest
  by the U.S. government or one of its agencies or instrumentalities; and

* other money market instruments.

The Fund invests only in instruments denominated and payable in U.S.
dollars.

  VARIABLE RATE DEMAND NOTES
 
  Variable rate demand notes are long-term debt instruments that have variable
  or floating interest rates and provide the Fund with the right to tender the
  security for repurchase at its stated principal amount plus accrued
  interest. Such securities typically bear interest at a rate that is intended
  to cause the securities to trade at par. The interest rate may float or be
  adjusted at regular intervals (ranging from daily to annually), and is
  normally based on a published interest rate or interest rate index. Most
  variable rate demand notes allow the Fund to demand the repurchase of the
  security on not more than seven days prior notice. Other notes only permit
  the Fund to tender the security at the time of each interest rate adjustment
  or at other fixed intervals. See "Demand Features." The Fund treats variable
  rate demand notes as maturing on the later of the date of the next interest
  rate adjustment or the date on which the Fund may next tender the security
  for repurchase.
 
  BANK INSTRUMENTS
 
  The Fund only invests in Bank Instruments either issued by an institution
  having capital, surplus and undivided profits over $100 million, or insured
  by the Bank Insurance Fund ("BIF") or the Savings Association Insurance Fund
  ("SAIF"). Bank Instruments may include Eurodollar Certificates of Deposit
  ("ECDs"), Yankee Certificates of Deposit ("Yankee CDs") and Eurodollar Time
  Deposits ("ETDs"). The Fund will treat securities credit enhanced with a
  bank's letter of credit as Bank Instruments.
 
  ASSET-BACKED SECURITIES
 
  Asset-backed securities are securities issued by special purpose entities
  whose primary assets consist of a pool of loans or accounts receivable. The
  securities may take the form of beneficial interests in special purpose
  trusts, limited partnership interests, or commercial paper or other debt
  securities issued by a special purpose corporation. Although the securities
  often have some form of credit or liquidity enhancement, payments on the
  securities depend predominantly upon collections of the loans and
  receivables held by the issuer.
 
  SHORT-TERM CREDIT FACILITIES
 
  The Fund may enter into, or acquire participations in, short-term borrowing
  arrangements with corporations, consisting of either a short-term revolving
  credit facility or a master note agreement payable upon demand. Under these
  arrangements, the borrower may reborrow funds during the term of the
  facility. The Fund treats any commitments to provide such advances as a
  standby commitment to purchase the borrower's notes.
 
REPURCHASE AGREEMENTS
 
Certain securities in which the Fund invests may be purchased pursuant to
repurchase agreements. Repurchase agreements are arrangements in which
banks, broker/dealers, and other recognized financial institutions sell
securities to the Fund and agree at the time of sale to repurchase them at a
mutually agreed upon time and price. To the extent that the seller does not
repurchase the securities from the Fund, the Fund could receive less than
the repurchase price on any sale of such securities.

CREDIT ENHANCEMENT

Certain of the Fund's acceptable investments may be credit-enhanced by a
guaranty, letter of credit, or insurance. Any bankruptcy, receivership,
default, or change in the credit quality of the party providing the credit
enhancement will adversely affect the quality and marketability of the
underlying security and could cause losses to the Fund and affect its share
price.

DEMAND FEATURES

The Fund may acquire securities that are subject to puts and standby
commitments ("demand features") to purchase the securities at their
principal amount (usually with accrued interest) within a fixed period
(usually seven days) following a demand by the Fund. The demand feature may
be issued by the issuer of the underlying securities, a dealer in the
securities, or by another third party, and may not be transferred separately
from the underlying security. The Fund uses these arrangements to provide
the Fund with liquidity and not to protect against changes in the market
value of the underlying securities. The bankruptcy, receivership, or default
by the issuer of the demand feature, or a default on the underlying security
or other event that terminates the demand feature before its exercise, will
adversely affect the liquidity of the underlying security. Demand features
that are exercisable even after a payment default on the underlying security
may be treated as a form of credit enhancement.

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

The Fund may purchase securities on a when-issued or delayed delivery basis.
These transactions are arrangements in which the Fund purchases securities
with payment and delivery scheduled for a future time. The seller's failure
to complete these transactions may cause the Fund to miss a price or yield
considered to be advantageous. Settlement dates may be a month or more after
entering into these transactions, and the market values of the securities
purchased may vary from the purchase prices.

The Fund may dispose of a commitment prior to settlement if the adviser
deems it appropriate to do so. In addition, the Fund may enter into
transactions to sell its purchase commitments to third parties at current
market values and simultaneously acquire other commitments to purchase
similar securities at later dates. The Fund may realize short-term profits
or losses upon the sale of such commitments.

LENDING OF PORTFOLIO SECURITIES

In order to generate additional income, the Fund may lend its portfolio
securities on a short-term or long-term basis, or both, to broker/dealers,
banks, or other institutional borrowers of securities. The Fund will only
enter into loan arrangements with broker/dealers, banks, or other
institutions which the adviser has determined are creditworthy under
guidelines established by the Fund's Trustees and will receive collateral at
all times equal to at least 100% of the value of the securities loaned.
There is the risk that when lending portfolio securities, the securities may
not be available to the Fund on a timely basis and the Fund may, therefore,
lose the opportunity to sell the securities at a desirable price. In
addition, in the event that a borrower of securities would file for
bankruptcy or become insolvent, disposition of the securities may be delayed
pending court action.

RESTRICTED AND ILLIQUID SECURITIES

The Fund may invest in restricted securities, and, as a matter of
fundamental investment policy which cannot be changed without shareholder
approval, will limit such investments to 10% of its net assets. This
restriction is not applicable to commercial paper issued under Section 4(2)
of the Securities Act of 1933. Restricted securities are any securities in
which the Fund may invest pursuant to its investment objective and policies
but which are subject to restrictions on resale under federal securities
law. Under criteria established by the Trustees, certain restricted
securities are determined to be liquid. As a matter of non-fundamental
investment policy, to the extent that restricted securities are not
determined to be liquid, the Fund will limit their purchase, together with
other illiquid securities, including non-negotiable time deposits, and
repurchase agreements providing for settlement in more than seven days after
notice, to 10% of its net assets.

CONCENTRATION OF INVESTMENTS

As a matter of policy which cannot be changed without shareholder approval,
the Fund will generally invest 25% or more of its total assets in commercial
paper issued by finance companies. The finance companies in which the Fund
intends to invest can be divided into two categories, commercial finance
companies and consumer finance companies. Commercial finance companies are
principally engaged in lending to corporations or other businesses. Consumer
finance companies are primarily engaged in lending to individuals. Captive
finance companies or finance subsidiaries which exist to facilitate the
marketing and financial activities of their parent will, for purposes of
industry concentration, be classified in the industry of their parent's
corporation. In addition, the Fund may invest 25% or more of the value of
its total assets in instruments issued by a U.S. branch of a domestic bank
or savings association having capital, surplus, and undivided profits in
excess of $100,000,000 at the time of investment. Concentrating investments
in one industry may subject the Fund to more risk than if it did not
concentrate.

INVESTMENT RISKS

ECDs, ETDs, Yankee CDs, Canadian Commercial Paper, and Europaper are subject
to different risks than domestic obligations of domestic banks or
corporations. Examples of these risks include international economic and
political developments, foreign governmental restrictions that may adversely
affect the payment of principal or interest, foreign withholding or other
taxes on interest income, difficulties in obtaining or enforcing a judgment
against the issuing entity, and the possible impact of interruptions in the
flow of international currency transactions. Risks may also exist for ECDs,
ETDs, and Yankee CDs because the banks issuing these instruments, or their
domestic or foreign branches, are not necessarily subject to the same
regulatory requirements that apply to domestic banks, such as reserve
requirements, loan limitations, examinations, accounting, auditing,
recordkeeping, and the public availability of information. These factors
will be carefully considered by the Fund's adviser in selecting investments
for the Fund.

INVESTMENT LIMITATIONS

The Fund will not borrow money directly or through reverse repurchase
agreements (arrangements in which the Fund sells a money market instrument
for a percentage of its cash value with an agreement to buy it back on a set
date) or pledge securities except, under certain circumstances, the Fund may
borrow up to one-third of the value of its total assets and pledge up to 15%
of the value of those assets to secure such borrowings. These investment
limitations cannot be changed without shareholder approval.

                              FUND INFORMATION

MANAGEMENT OF THE FUND

BOARD OF TRUSTEES

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

INVESTMENT ADVISER

Investment decisions for the Fund are made by Federated Management, the
Fund's investment adviser, subject to direction by the Trustees. The adviser
continually conducts investment research and supervision for the Fund and is
responsible for the purchase and sale of portfolio instruments.

  ADVISORY FEES
 
  The adviser receives an annual investment advisory fee equal to 0.20% of the
  Fund's average daily net assets. The adviser may voluntarily choose to waive
  a portion of its fee or reimburse other expenses of the Fund, but reserves
  the right to terminate such waiver or reimbursement at any time at its sole
  discretion.
 
  ADVISER'S BACKGROUND
 
  Federated Management, a Delaware business trust, organized on April 11,
  1989, is a registered investment adviser under the Investment Advisers Act
  of 1940. It is a subsidiary of Federated Investors. All of the Class A
  (voting) shares of Federated Investors are owned by a trust, the trustees of
  which are John F. Donahue, Chairman and Trustee of Federated Investors, Mr.
  Donahue's wife, and Mr. Donahue's son, J. Christopher Donahue, who is
  President and Trustee of Federated Investors.
 
  Federated Management and other subsidiaries of Federated Investors serve as
  investment advisers to a number of investment companies and private
  accounts. Certain other subsidiaries also provide administrative services to
  a number of investment companies. With over $110 billion invested across
  over 300 funds under management and/or administration by its subsidiaries,
  as of December 31, 1996, Federated Investors is one of the largest mutual
  fund investment managers in the United States. With more than 2,000
  employees, Federated continues to be led by the management who founded the
  company in 1955. Federated funds are presently at work in and through 4,500
  financial institutions nationwide.
 
Both the Trust and the adviser have adopted strict codes of ethics governing
the conduct of all employees who manage the Fund and its portfolio
securities. These codes recognize that such persons owe a fiduciary duty to
the Fund's shareholders and must place the interests of shareholders ahead
of the employees' own interests. Among other things, the codes: require
preclearance and periodic reporting of personal securities transactions;
prohibit personal transactions in securities being purchased or sold, or
being considered for purchase or sale, by the Fund; prohibit purchasing
securities in initial public offerings; and prohibit taking profits on
securities held for less than sixty days. Violations of the codes are
subject to review by the Trustees, and could result in severe penalties.

DISTRIBUTION OF INSTITUTIONAL SERVICE SHARES

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

SHAREHOLDER SERVICES

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

SUPPLEMENTAL PAYMENTS TO FINANCIAL INSTITUTIONS

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

ADMINISTRATION OF THE FUND

ADMINISTRATIVE SERVICES

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

MAXIMUM                AVERAGE AGGREGATE
  FEE                   DAILY NET ASSETS

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

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

                              NET ASSET VALUE

The Fund attempts to stabilize the net asset value of shares at $1.00 by
valuing the portfolio securities using the amortized cost method. The net
asset value per share is determined by subtracting liabilities attributable
to Institutional Service Shares from the value of Fund assets attributable
to Institutional Service Shares, and dividing the remainder by the number of
Institutional Service Shares outstanding. The Fund cannot guarantee that its
net asset value will always remain at $1.00 per share.

The net asset value is determined at 5:00 p.m. (Eastern time), Monday
through Friday, except on New Year's Day, Martin Luther King Day,
Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day,
Thanksgiving Day, and Christmas Day.

                           HOW TO PURCHASE SHARES

Shares are sold at their net asset value, without a sales charge, next
determined after an order is received, on days on which the New York Stock
Exchange is open for business. Shares may be purchased either by wire or by
check. The Fund reserves the right to reject any purchase request.

To make a purchase, open an account by calling Federated Securities Corp.
Information needed to establish the account will be taken by telephone. The
minimum initial investment is $1,000,000. However, an account may be opened
with a smaller amount as long as the minimum is reached within one year of
opening the account. Financial institutions may impose different minimum
investment requirements on their customers.

PURCHASING SHARES BY WIRE

Shares may be purchased by Federal Reserve wire by calling the Fund before
5:00 p.m. (Eastern time) to place an order. The order is considered received
immediately. Payment by federal funds must be received before 5:00 p.m.
(Eastern time) that day. Federal funds should be wired as follows: Federated
Shareholder Services Company, c/o State Street Bank and Trust Company,
Boston, MA; Attention: EDGEWIRE; For Credit to: Prime Obligations
Fund--Institutional Service Shares; Fund Number (this number can be found on
the account statement or by contacting the Fund); Group Number or Order
Number; Nominee or Institution Name; and ABA Number 011000028. Shares cannot
be purchased by wire on holidays when wire transfers are restricted.
Questions on wire purchases should be directed to your shareholder services
representative at the telephone number listed on your account statement.

PURCHASING SHARES BY CHECK

Shares may be purchased by sending a check to Federated Shareholder Services
Company, P.O. Box 8600, Boston, MA 02266-8600. The check should be made
payable to: Prime Obligations Fund -- Institutional Service Shares. 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.

INVEST-BY-PHONE

Once an account has been opened, a shareholder may use invest-by-phone for
investments if an authorization form has been filed with Federated
Shareholder Services Company, the transfer agent for shares of the Fund.
Approximately two weeks after sending the form to Federated Shareholder
Services Company, the shareholder may call Federated Shareholder Services
Company to purchase shares. Federated Shareholder Services Company will send
a request for monies to the shareholder's commercial bank, savings bank, or
credit union ("bank") via the Automated Clearing House. The shareholder's
bank, which must be an Automated Clearing House member, will then forward
the monies to Federated Shareholder Services Company. The purchase is
normally entered the next business day after the initial phone request. For
further information and an application, call the Fund.

                            HOW TO REDEEM SHARES

Shares are redeemed at their net asset value next determined after Federated
Shareholder Services Company receives the redemption request. Redemptions
will be made on days on which the Fund computes its net asset value.
Redemption requests must be received in proper form and can be made as
described below.

REDEEMING SHARES BY TELEPHONE

Redemptions in any amount may be made by calling the Fund provided the Fund
has a properly completed authorization form. These forms can be obtained
from Federated Securities Corp. Proceeds from redemption requests received
before 5:00 p.m. (Eastern time) will be wired the same day to the
shareholder's account at a domestic commercial bank which is a member of the
Federal Reserve System, but will not include that day's dividend. Proceeds
from redemption requests on holidays when wire transfers are restricted will
be wired the following business day. Questions about telephone redemptions
on days when wire transfers are restricted should be directed to your
shareholder services representative at the telephone number listed on your
account statement.

Telephone instructions may be recorded and if reasonable procedures are not
followed by the Fund, it may be liable for losses due to unauthorized or
fraudulent telephone instructions.

In the event of drastic economic or market changes, a shareholder may
experience difficulty in redeeming by telephone. If this occurs, "Redeeming
Shares by Mail" should be considered. If at any time the Fund shall
determine it necessary to terminate or modify the telephone redemption
privilege, shareholders would be promptly notified.

REDEEMING SHARES BY MAIL

Shares may be redeemed in any amount by mailing a written request to:
Federated Shareholder Services Company, P.O. Box 8600, Boston, MA
02266-8600. If share certificates have been issued, they should be sent
unendorsed with the written request by registered or certified mail to the
address noted above.

The written request should state: the Fund name and the class designation;
the account name as registered with the Fund; the account number; and the
number of shares to be redeemed or the dollar amount requested. All owners
of the account must sign the request exactly as the shares are registered.
Normally, a check for the proceeds is mailed within one business day, but in
no event more than seven days, after the receipt of a proper written
redemption request. Dividends are paid up to and including the day that a
redemption request is processed.

Shareholders requesting a redemption of any amount to be sent to an address
other than that on record with the Fund or a redemption payable other than
to the shareholder of record must have their signatures guaranteed by a
commercial or savings bank, trust company or savings association whose
deposits are insured by an organization which is administered by the Federal
Deposit Insurance Corporation; a member firm of a domestic stock exchange;
or any other "eligible guarantor institution," as defined in the Securities
Exchange Act of 1934. The Fund does not accept signatures guaranteed by a
notary public.

                       ACCOUNT AND SHARE INFORMATION

DIVIDENDS

Dividends are declared daily and paid monthly. Dividends are automatically
reinvested on payment dates in additional shares of the Fund unless cash
payments are requested by writing to the Fund. Shares purchased by wire
before 5:00 p.m. (Eastern time) begin earning dividends that day. Shares
purchased by check begin earning dividends the day after the check is
converted into federal funds.

CAPITAL GAINS

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 will distribute in cash or additional shares any
realized net long-term capital gains at least once every 12 months.

CONFIRMATIONS AND ACCOUNT STATEMENTS

Shareholders will receive detailed confirmations of transactions (except for
systematic program transactions). In addition, shareholders will receive
periodic statements reporting all account activity, including dividends
paid. The Fund will not issue share certificates.

ACCOUNTS WITH LOW BALANCES

Due to the high cost of maintaining accounts with low balances, the Fund may
redeem shares in any account, except accounts maintained by retirement
plans, and pay the proceeds to the shareholder if the account balance falls
below a required minimum value of $1,000,000 due to shareholder redemptions.
Before shares are redeemed to close an account, the shareholder is notified
in writing and allowed 30 days to purchase additional shares to meet the
minimum requirement.

VOTING RIGHTS

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

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

                              TAX INFORMATION

FEDERAL INCOME TAX

The Fund will pay no federal income tax because it expects to meet
requirements of the Internal Revenue Code applicable to regulated investment
companies and to receive the special tax treatment afforded to such
companies. The Fund will be treated as a single, separate entity for federal
income tax purposes so that income (including capital gains) and losses
realized by the Trust's other portfolios will not be combined for tax
purposes with those realized by the Fund.

Unless otherwise exempt, shareholders are required to pay federal income tax
on any dividends and other distributions received. This applies whether
dividends and distributions are received in cash or as additional shares.

STATE AND LOCAL TAXES

In the opinion of Houston, Donnelly & Meck, counsel to the Trust, Fund
shares may be subject to personal property taxes imposed by counties,
municipalities, and school districts in Pennsylvania to the extent that the
portfolio securities in the Fund would be subject to such taxes if owned
directly by residents of those jurisdictions.

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

                          OTHER CLASSES OF SHARES

The Fund also offers other classes. Institutional Shares are sold at net
asset value primarily to entities holding shares in an agency or fiduciary
capacity, financial institutions, financial intermediaries and institutional
investors and are subject to a minimum initial investment of $1,000,000.

All classes are subject to certain of the same expenses.

Institutional Shares are distributed with no 12b-1 Plan but are subject to
shareholder services fees.

Expense differences between classes may affect the performance of each
class.

To obtain more information and a prospectus for any other class, investors
may call 1-800-341-7400.

                          PERFORMANCE INFORMATION

From time to time, the Fund advertises its yield, effective yield and total
return. The performance figures will be calculated separately for each class
of shares.

Yield represents the annualized rate of income earned on an investment over
a seven-day period. It is the annualized dividends earned during the period
on an investment shown as a percentage of the investment. The effective
yield is calculated similarly to the yield, but when annualized, the income
earned by an investment is assumed to be reinvested daily. The effective
yield will be slightly higher than the yield because of the compounding
effect of this assumed reinvestment.

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

From time to time, advertisements for the Fund may refer to ratings,
rankings, and other information in certain financial publications and/or

The Fund uses the amortized cost method to value its portfolio securities in
accordance with Rule 2a-7 under the Act.

REPURCHASE AGREEMENTS

It is the policy of the Fund to require the custodian bank to take
possession, to have legally segregated in the Federal Reserve Book Entry
System, or to have segregated within the custodian bank's vault, all
securities held as collateral under repurchase agreement transactions.
Additionally, procedures have been established by the Fund to monitor, on a
daily basis, the market value of each repurchase agreement's collateral to
ensure that the value of collateral at least equals the repurchase price to
be paid under the repurchase agreement transaction.

The Fund will only enter into repurchase agreements with banks and other
recognized financial institutions, such as broker/dealers, which are deemed
by the Fund's adviser to be creditworthy pursuant to the guidelines and/or
standards reviewed or established by the Board of Trustees (the "Trustees").
Risks may arise from the potential inability of counterparties to honor the
terms of the repurchase agreement. Accordingly, the Fund could receive less
than the repurchase price on the sale of collateral securities.

INVESTMENT INCOME, EXPENSES AND DISTRIBUTIONS

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

FEDERAL TAXES

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

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

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

RESTRICTED SECURITIES

Restricted securities are securities that may only be resold upon
registration under federal securities laws or in transactions exempt from
such registration. Many restricted securities may be resold in the secondary
market in transactions exempt from registration. In some cases, the
restricted securities may be resold without registration upon exercise of a
demand feature. Such restricted securities may be determined to be liquid
under criteria established by the Trustees. The Fund will not incur any
registration costs upon such resales. Restricted securities are valued at
amortized cost in accordance with Rule 2a-7 under the Act.

Additional information on each restricted security held at July 31, 1997 is

USE OF ESTIMATES

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

OTHER

Investment transactions are accounted for on the trade date.

of full and fractional shares of beneficial interest (without par value) for
each class of shares. At July 31, 1997, capital paid-in aggregated

                  REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Shareholders of Board of Trustees of
MONEY MARKET OGLIBATIONS TRUST
(Prime Obligations Fund):

We have audited the accompanying statement of assets and liabilities of
Prime Obligations Fund (an investment portfolio of Money Market Obligations
Trust, a Massachusetts business trust), including the schedule of portfolio
investments, as of July 31, 1997, the related statement of operations for
the year then ended, the statement of changes in net assets for each of the
two years in the period then ended, and the financial highlights for the
periods presented. These financial statements and financial highlights are
the responsibility of the Trust's management. Our responsibility is to
express an opinion on these financial statements and financial highlights
based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements and
financial highlights are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures
in the financial statements. Our procedures included confirmation of
securities owned as of July 31, 1997, by correspondence with the custodian.
An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of
Prime Obligations Fund (an investment portfolio of Money Market Obligations
Trust) as of July 31, 1997, the results of its operations for the year then
ended, the changes in its net assets for each of the two years in the period
then ended, and its financial highlights for the periods presented, in
conformity with generally accepted accounting principles.

INVESTMENT POLICIES

Unless indicated otherwise, the policies described below may be changed by
the Board of Trustees (the "Trustees") without shareholder approval.
Shareholders will be notified before any material change in these policies
becomes effective.

ACCEPTABLE INVESTMENTS

When determining whether a security presents minimal credit risks, the
investment adviser will consider the creditworthiness of: the issuer of the
security; the issuer of any demand feature applicable to the security; or
any guarantor of either the security or any demand feature.

U.S. GOVERNMENT SECURITIES

The types of U.S. government securities in which the Fund may invest
generally include direct obligations of the U.S. Treasury (such as U.S.
Treasury bills, notes, and bonds) and obligations issued or guaranteed by
U.S. government agencies or instrumentalities. These securities are backed
by:

   * the full faith and credit of the U.S. Treasury;
   * the issuer's right to borrow from the U.S. Treasury;
   * the discretionary authority of the U.S. government to purchase certain
     obligations of agencies or instrumentalities; or
   * the credit of the agency or instrumentality issuing the obligations.

BANK INSTRUMENTS

The instruments of banks and savings associations whose deposits are insured
by the Bank Insurance Fund ("BIF") or the Savings Association Insurance Fund
("SAIF"), such as certificates of deposit, demand and time deposits, savings
shares, and bankers' acceptances, are not necessarily guaranteed by those
organizations. In addition to domestic bank instruments, the Fund may invest
in: Eurodollar Certificates of Deposit issued by foreign branches of U.S. or
foreign banks; Eurodollar Time Deposits, which are U.S. dollar-denominated
deposits in foreign branches of U.S. or foreign banks; Canadian Time
Deposits, which are U.S. dollar-denominated deposits issued by branches of
major Canadian banks located in the United States; and Yankee Certificates
of Deposit, which are U.S. dollar-denominated certificates of deposit issued
by U.S. branches of foreign banks and held in the United States.

RATINGS

An NRSRO's highest rating category is determined without regard for
sub-categories and gradations. For example, securities rated A-1 or A-1+ by
Standard & Poor's Ratings Group ("S&P"), Prime-1 by Moody's Investors
Service, Inc. ("Moody's"), or F-1 (+ or -) by Fitch Investors Service, Inc.
("Fitch") are all considered rated in the highest short-term rating
category. The Fund will follow applicable regulations in determining whether
a security rated by more than one NRSRO can be treated as being in the
highest short-term rating category; currently, such securities must be rated
by two NRSROs in their highest rating category. See "Regulatory Compliance."

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

These transactions are made to secure what is considered to be an
advantageous price or yield for the Fund. No fees or other expenses, other
than normal transaction costs, are incurred. However, liquid assets of the
Fund in a dollar amount sufficient to make payment for the securities to be
purchased are: segregated on the Fund's records at the trade date; marked to
market daily; and maintained until the transaction is settled. The Fund does
not intend to engage in when-issued and delayed delivery transactions to an
extent that would cause the segregation of more than 20% of the total value
of its assets.

REPURCHASE AGREEMENTS

The Fund believes that under the regular procedures normally in effect for
custody of the Fund's portfolio securities subject to repurchase agreements,
a court of competent jurisdiction would rule in favor of the Fund and allow
retention or disposition of such securities. The Fund will only enter into
repurchase agreements with banks and other recognized financial
institutions, such as broker/dealers, which are deemed by the Fund's adviser
to be creditworthy pursuant to guidelines established by the Trustees.

RESTRICTED AND ILLIQUID SECURITIES

The Fund may invest in commercial paper issued in reliance on the exemption
from registration afforded by Section 4(2) of the Securities Act of 1933.
Section 4(2) commercial paper is restricted as to disposition under federal
securities law, and is generally sold to institutional investors, such as
the Fund, who agree that they are purchasing the paper for investment
purposes and not with a view to public distribution. Any resale by the
purchaser must be in an exempt transaction. Section 4(2) commercial paper is
normally resold to other institutional investors like the Fund through or
with the assistance of the issuer or investment dealers who make a market in
Section 4(2) commercial paper, thus providing liquidity. The Fund believes
that Section 4(2) commercial paper and possibly certain other restricted
securities which meet the criteria for liquidity established by the Trustees
of the Fund are quite liquid. The Fund intends, therefore, to treat the
restricted securities which meet the criteria for liquidity established by
the Trustees, including Section 4(2) commercial paper, as determined by the
Fund's investment adviser, as liquid and not subject to the investment
limitation applicable to illiquid securities.

REVERSE REPURCHASE AGREEMENTS

The Fund may also enter into reverse repurchase agreements. These
transactions are similar to borrowing cash. In a reverse repurchase
agreement, the Fund transfers possession of a portfolio instrument in return
for a percentage of the instrument's market value in cash and agrees that on
a stipulated date in the future the Fund will repurchase the portfolio
instrument by remitting the original consideration plus interest at an
agreed-upon rate. The use of reverse repurchase agreements may enable the
Fund to avoid selling portfolio instruments at a time when a sale may be
deemed to be disadvantageous, but does not ensure this result. However,
liquid assets of the Fund, in a dollar amount sufficient to make payment for
the securities to be purchased, are: segregated on the Fund's records at the
trade date; marked to market daily; and maintained until the transaction is
settled.

CREDIT ENHANCEMENT

The Fund typically evaluates the credit quality and ratings of
credit-enhanced securities based upon the financial condition and ratings of
the party providing the credit enhancement (the "credit enhancer"), rather
than the issuer. Generally, the Fund will not treat credit-enhanced
securities as being issued by the credit enhancer for diversification
purposes. However, under certain circumstances applicable regulations may
require the Fund to treat securities as having been issued by both the
issuer and the credit enhancer.

LENDING OF PORTFOLIO SECURITIES

The collateral received when the Fund lends portfolio securities must be
valued daily and, should the market value of the loaned securities increase,
the borrower must furnish additional collateral to the Fund. During the time
portfolio securities are on loan, the borrower pays the Fund any dividends
or interest paid on such securities. Loans are subject to termination at the
option of the Fund or the borrower. The Fund may pay reasonable
administrative and custodial fees in connection with a loan and may pay a
negotiated portion of the interest earned on the cash or equivalent
collateral to the borrower or placing broker.

INVESTMENT LIMITATIONS

SELLING SHORT AND BUYING ON MARGIN

The Fund will not sell any securities short or purchase any securities on
margin but may obtain such short-term credits as are necessary for clearance
of transactions.

ISSUING SENIOR SECURITIES AND BORROWING MONEY

The Fund will not issue senior securities except that the Fund may borrow
money directly or through reverse repurchase agreements in amounts up to
one-third of the value of its total assets, including the amounts borrowed.

The Fund will not borrow money or engage in reverse repurchase agreements
for investment leverage, but rather as a temporary, extraordinary, or
emergency measure or to facilitate management of the portfolio by enabling
the Fund to meet redemption requests when the liquidation of portfolio
securities is deemed to be inconvenient or disadvantageous. The Fund will
not purchase any securities while borrowings in excess of 5% of the value of
its total assets are outstanding. During the period any reverse repurchase
agreements are outstanding, the Fund will restrict the purchase of portfolio
securities to money market instruments maturing on or before the expiration
date of the reverse repurchase agreements, but only to the extent necessary
to assure completion of the reverse repurchase agreements.

PLEDGING ASSETS

The Fund will not mortgage, pledge, or hypothecate any assets except to
secure permitted borrowings. In those cases, it may pledge assets having a
market value not exceeding the lesser of the dollar amounts borrowed or 15%
of the value of total assets of the Fund at the time of the pledge.

LENDING CASH OR SECURITIES

The Fund will not lend any assets, except portfolio securities. This shall
not prevent the Fund from purchasing or holding bonds, debentures, notes,
certificates of indebtedness, or other debt securities; entering into
repurchase agreements; or engaging in other transactions permitted by its
investment objective, policies, and limitations, or the Trust's Declaration
of Trust.

INVESTING IN COMMODITIES

The Fund will not purchase or sell commodities, commodity contracts, or
commodity futures contracts.

INVESTING IN REAL ESTATE

The Fund will not purchase or sell real estate, although it may invest in
securities of issuers whose business involves the purchase or sale of real
estate or in securities which are secured by real estate or interests in
real estate.

UNDERWRITING

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

CONCENTRATION OF INVESTMENTS

The Fund will not invest 25% or more of the value of its total assets in any
one industry except that the Fund will generally invest 25% or more of the
value of its total assets in commercial paper issued by finance companies.
The Fund may invest 25% or more of the value of its total assets in cash,
cash items, (including demand deposits issued by a U.S. branch of a domestic
bank or savings and loan having capital, surplus, and undivided profits in
excess of $100,000,000 at the time of investment), or securities issued or
guaranteed by the government of the United States or its agencies, or
instrumentalities or instruments secured by these money market instruments,
such as repurchase agreements.

DIVERSIFICATION OF INVESTMENTS

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, or 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) if as a result more than
5% of the value of its total assets would be invested in the securities of
that issuer.

RESTRICTED SECURITIES

The Fund will not invest more than 10% of the value of its net assets in
securities which are subject to legal or contractual restrictions on resale,
except for commercial paper issued under Section 4 (2) of the Securities Act
of 1933.

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

INVESTING IN ILLIQUID SECURITIES

The Fund will not invest more than 10% of the value of its net assets in
illiquid securities, including certain restricted securities not determined
to be liquid under criteria established by the Trustees, non-negotiable time
deposits, and repurchase agreements providing for settlement in more than
seven days after notice.

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.

INVESTING FOR CONTROL

The Fund will not invest in securities of a company for the purpose of
exercising control or management.

INVESTING IN OPTIONS

The Fund will not invest in puts, calls, straddles, spreads, or any
combination of them.

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.

The Fund did not borrow money or pledge securities in excess of 5% of the
value of its net assets during the last fiscal year and has no present
intent to do so during the coming fiscal year.

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, which regulates
money market mutual funds. The Fund also will determine the effective
maturity of its investments, as well as its ability to consider a security
as having received the requisite short-term ratings by NRSROs, according to
Rule 2a-7. The Fund may change these operational policies to reflect changes
in the laws and regulations without the approval of its shareholders.

TRUSTEE LIABILITY

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

INVESTMENT ADVISORY SERVICES

INVESTMENT ADVISER

The Fund's investment adviser is Federated Management. It is a subsidiary of
Federated Investors. All the voting securities of Federated Investors are
owned by a trust, the trustees of which are John F. Donahue, his wife, and
his son, J. Christopher Donahue.

The adviser shall not be liable to the Trust, the Fund, or any shareholder
of the Fund 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.

ADVISORY FEES

For its advisory services, Federated Management receives an annual
investment advisory fee as described in the prospectus. For the fiscal years
ended July 31, 1997, 1996, and 1995, the adviser earned $10,030,131,
$7,504,715, and $4,370,903, respectively, of which $5,562,429, $4,114,750,
and $2,828,160, respectively, were waived.

BROKERAGE TRANSACTIONS

When selecting brokers and dealers to handle the purchase and sale of
portfolio instruments, the adviser looks for prompt execution of the order
at a favorable price. In working with dealers, the adviser will generally
use those who are recognized dealers in specific portfolio instruments,
except when a better price and execution of the order can be obtained
elsewhere. The adviser makes decisions on portfolio transactions and selects
brokers and dealers subject to guidelines established by the Trustees. The
adviser may select brokers and dealers who offer brokerage and research
services. These services may be furnished directly to the Fund or to the
adviser and may include: advice as to the advisability of investing in
securities; security analysis and reports; economic studies; industry
studies; receipt of quotations for portfolio evaluations; and similar
services. Research services provided by brokers and dealers may be used by
the adviser or its affiliates in advising the Fund and other accounts. To
the extent that receipt of these services may supplant services for which
the adviser or its affiliates might otherwise have paid, it would tend to
reduce their expenses. The adviser and its affiliates exercise reasonable
business judgment in selecting brokers who offer brokerage and research
services to execute securities transactions. They determine in good faith
that commissions charged by such persons are reasonable in relationship to
the value of the brokerage and research services provided. During the fiscal
years ended July 31, 1997, 1996, and 1995, the Fund paid no brokerage
commissions.

Although investment decisions for the Fund are made independently from those
of the other accounts managed by the adviser, investments of the type the
Fund may make may also be made by those other accounts. When the Fund and
one or more other accounts managed by the adviser are prepared to invest in,
or desire to dispose of, the same security, available investments or
opportunities for sales will be allocated in a manner believed by the
adviser to be equitable to each. In some cases, this procedure may adversely
affect the price paid or received by the Fund or the size of the position
obtained or disposed of by the Fund. In other cases, however, it is believed
that coordination and the ability to participate in volume transactions will
be to the benefit of the Fund.

OTHER SERVICES

FUND ADMINISTRATION

Federated Services Company, a subsidiary of Federated Investors, provides
administrative personnel and services to the Fund for a fee as described in
the prospectus. From March 1, 1994, to March 1, 1996, Federated
Administrative Services, a subsidiary of Federated Investors, served as the
Fund's Administrator. For purposes of this Statement of Additional
Information, Federated Services Company and Federated Administrative
Services may hereinafter collectively be referred to as the
"Administrators." For the fiscal years ended July 31, 1997, 1996, and 1995,
the Administrators earned $3,787,706, $2,837,919, and $1,654,387,
respectively.

CUSTODIAN AND PORTFOLIO ACCOUNTANT

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

TRANSFER AGENT

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

INDEPENDENT PUBLIC ACCOUNTANTS

The independent public accountants for the Fund are Arthur Andersen LLP,
Pittsburgh, Pennsylvania.

SHAREHOLDER SERVICES

This arrangement permits the payment of fees to Federated Shareholder
Services to cause services to be provided which are necessary for the
maintenance of shareholder accounts and to encourage personal services to
shareholders by a representative who has knowledge of the shareholder's
particular circumstances and goals. These activities and services may
include but are not limited to providing office space, equipment, telephone
facilities, and various clerical, supervisory, computer, and other personnel
as necessary or beneficial to establish and maintain shareholder accounts
and records; processing purchase and redemption transactions and automatic
investments of client account cash balances; answering routine client
inquiries; and assisting clients in changing dividend options, account
designations, and addresses.

By adopting the Shareholder Services Agreement, the Trustees expect that the
Fund will benefit by: (1) providing personal services to shareholders; (2)
investing shareholder assets with a minimum of delay and administrative
detail; (3) enhancing shareholder recordkeeping systems; and (4) responding
promptly to shareholders' requests and inquiries concerning their accounts.

For the fiscal year ended July 31, 1997, the Fund earned shareholder service
fees on behalf of Institutional Shares and Institutional Service Shares in
the amounts of $8,188,378 and $4,349,287, respectively, $0 and $4,349,287 of
which, respectively, was paid to financial institutions.

DETERMINING NET ASSET VALUE

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 Rule 2a-7 (the "Rule")
promulgated by the Securities and Exchange Commission under the Investment
Company Act of 1940. 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.

REDEMPTION IN KIND

The Fund is obligated to redeem shares solely in cash up to $250,000 or 1%
of the Fund's net asset value, whichever is less, for any one shareholder
within a 90-day period. Any redemption beyond this amount will also be in
cash unless the Trustees determine that further payments should be in kind.
In such cases, the Fund will pay all or a portion of the remainder of the
redemption in portfolio instruments valued in the same way as the Fund
determines net asset value. The portfolio instruments will be selected in a
manner that the Trustees deem fair and equitable. Redemption in kind is not
as liquid as a cash redemption. If redemption is made in kind, shareholders
who sell these securities could receive less than the redemption value and
could incur certain transaction costs.

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. These documents require notice of this disclaimer
to be given in each agreement, obligation, or instrument the Trust or its
Trustees enter into or sign.

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.

THE FUND'S TAX STATUS

To qualify for the special tax treatment afforded to regulated investment
companies, the Fund must, among other requirements: derive at least 90% of
its gross income from dividends, interest, and gains from the sale of
securities; derive less than 30% of its gross income from the sale of
securities held less than three months; invest in securities within certain
statutory limits; and distribute to its shareholders at least 90% of its net
income earned during the year.

PERFORMANCE INFORMATION

Performance depends upon such variables as: portfolio quality; average
portfolio maturity; type of instruments in which the portfolio is invested;
changes in interest rates; changes in expenses; and the relative amount of
cash flow. To the extent that financial institutions and broker/dealers
charge fees in connection with services provided in conjunction with an
investment in shares of the Fund, the performance will be reduced for those
shareholders paying those fees.

YIELD

The yield is calculated based upon the seven days ending on the day of the
calculation, called the "base period." This yield is computed 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.

For the seven-day period ended July 31, 1997, the yield for Institutional
Shares and Institutional Service Shares was 5.49%, and 5.24%, respectively.

EFFECTIVE YIELD

The effective yield is calculated by compounding the unannualized
base-period return by: adding 1 to the base-period return; raising the sum
to the 365/7th power; and subtracting 1 from the result.

For the seven-day period ended July 31, 1997, the effective yield for
Institutional Shares and Institutional Service Shares was 5.64% and 5.38%,
respectively.

TOTAL RETURN

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

Prior to the creation of separate classes of shares, for the one-year and
five-year periods ended July 31, 1997, and for the period from May 26, 1990,
(start of performance) to July 31, 1997, the average annual total returns
were 5.45%, 4.67%, and 5.22%, respectively, for Institutional Shares.

For the one-year period ended July 31, 1997, and for the period from July 5,
1994, (date of initial public offering) through July 31, 1997, the average
annual total returns were 5.19% and 5.27%, respectively, for Institutional
Service Shares.

complete view of the Fund's performance. When comparing performance,
investors should consider all relevant factors such as the composition of
any index used, prevailing market conditions, portfolio compositions of

GENERAL INFORMATION

The Trust was established as a Massachusetts business trust under a
Declaration of Trust dated October 3, 1988. The Declaration of Trust permits
the Trust to offer separate series of shares representing interests in
separate portfolios of securities. The shares in any one portfolio may be
offered in separate classes. With respect to this Fund, as of the date of
this prospectus, the Board of Trustees (the "Trustees") has established two
classes of shares known as Institutional Shares and Institutional Service
Shares. This prospectus relates only to Institutional Shares of the Fund,
which are designed primarily for entities holding shares in an agency or
fiduciary capacity, financial institutions, financial intermediaries and
institutional investors as a convenient means of accumulating an interest in
a professionally managed portfolio investing primarily in short-term
municipal securities. The Fund may not be a suitable investment for
retirement plans because it invests in municipal securities. A minimum
initial investment of $1,000,000 over a one-year period is required.

The Fund attempts to stabilize the value of a share at $1.00. Shares are
currently sold and redeemed at that price.

INVESTMENT INFORMATION

INVESTMENT OBJECTIVE

The investment objective of the Fund is to provide dividend income exempt
from federal regular income tax consistent with stability of principal. This
investment objective cannot be changed without shareholder approval. While
there is no assurance that the Fund will achieve its investment objective,
it endeavors to do so by complying with the diversification and other
requirements of Rule 2a-7 under the Investment Company Act of 1940 which
regulates money market mutual funds and by following the investment policies
described in this prospectus.

INVESTMENT POLICIES

The Fund pursues its investment objective by investing in a portfolio of
municipal securities maturing in 13 months or less. The average maturity of
the securities in the Fund's portfolio, computed on a dollar-weighted basis,
will be 90 days or less. As a matter of investment policy, which cannot be
changed without shareholder approval, at least 80% of the Fund's annual
interest income will be exempt from federal regular income tax. (Federal
regular income tax does not include the federal individual alternative
minimum tax or the federal alternative minimum tax for corporations.) Unless
indicated otherwise, the investment policies may be changed by the Trustees
without shareholder approval. Shareholders will be notified before any
material change in these policies becomes effective.

ACCEPTABLE INVESTMENTS

The Fund invests primarily in debt obligations issued by or on behalf of
states, territories, and possessions of the United States, including the
District of Columbia, and any political subdivision or financing authority
of any of these, the income from which is, in the opinion of qualified legal
counsel, exempt from federal regular income tax ("Municipal Securities").
Examples of Municipal Securities include, but are not limited to:

   * tax and revenue anticipation notes issued to finance working capital
     needs in anticipation of receiving taxes or other revenues;
   * bond anticipation notes that are intended to be refinanced through a
     later issuance of longer-term bonds;
   * municipal commercial paper and other short-term notes;
   * variable rate demand notes;
   * municipal bonds (including bonds having serial maturities and
     pre-refunded bonds) and leases; and
   * participation, trust, and partnership interests in any of the foregoing
     obligations.

VARIABLE RATE DEMAND NOTES

Variable rate demand notes are long-term debt instruments that have variable
or floating interest rates and provide the Fund with the right to tender the
security for repurchase at its stated principal amount plus accrued
interest. Such securities typically bear interest at a rate that is intended
to cause the securities to trade at par. The interest rate may float or be
adjusted at regular intervals (ranging from daily to annually), and is
normally based on a published interest rate or interest rate index. Most
variable rate demand notes allow the Fund to demand the repurchase of the
security on not more than seven days prior notice. Other notes only permit
the Fund to tender the security at the time of each interest rate adjustment
or at other fixed intervals. See "Demand Features." The Fund treats variable
rate demand notes as maturing on the later of the date of the next interest
rate adjustment or the date on which the Fund may next tender the security
for repurchase.

PARTICIPATION INTERESTS

The Fund may purchase interests in Municipal Securities from financial
institutions such as commercial and investment banks, savings associations,
and insurance companies. These interests may take the form of
participations, beneficial interests in a trust, partnership interests or
any other form of indirect ownership that allows the Fund to treat the
income from the investment as exempt from federal income tax. The Fund
invests in these participation interests in order to obtain credit
enhancement or demand features that would not be available through direct
ownership of the underlying Municipal Securities.

MUNICIPAL LEASES

Municipal leases are obligations issued by state and local governments or
authorities to finance the acquisition of equipment and facilities. They may
take the form of a lease, an installment purchase contract, a conditional
sales contract, or a participation interest in any of the above. Lease
obligations may be subject to periodic appropriation. Municipal leases are
subject to certain specific risks in the event of default or failure of
appropriation.

CREDIT ENHANCEMENT

Certain of the Fund's acceptable investments may be credit-enhanced by a
guaranty, letter of credit, or insurance. Any bankruptcy, receivership,
default, or change in the credit quality of the party providing the credit
enhancement will adversely affect the quality and marketability of the
underlying security and could cause losses to the Fund and affect its share
price. The Fund may have more than 25% of its total assets invested in
securities credit-enhanced by banks.

DEMAND FEATURES

The Fund may acquire securities that are subject to puts and standby
commitments ("demand features") to purchase the securities at their
principal amount (usually with accrued interest) within a fixed period
(usually seven days) following a demand by the Fund. The demand feature may
be issued by the issuer of the underlying securities, a dealer in the
securities, or by another third party, and may not be transferred separately
from the underlying security. The Fund uses these arrangements to provide
the Fund with liquidity and not to protect against changes in the market
value of the underlying securities. The bankruptcy, receivership, or default
by the issuer of the demand feature, or a default on the underlying security
or other event that terminates the demand feature before its exercise, will
adversely affect the liquidity of the underlying security. Demand features
that are exercisable even after a payment default on the underlying security
may be treated as a form of credit enhancement.

The Fund may purchase securities on a when-issued or delayed delivery basis.
These transactions are arrangements in which the Fund purchases securities
with payment and delivery scheduled for a future time. The seller's failure
to complete these transactions may cause the Fund to miss a price or yield
considered to be advantageous. Settlement dates may be a month or more after
entering into these transactions, and the market values of the securities
purchased may vary from the purchase prices.

The Fund may dispose of a commitment prior to settlement if the adviser
deems it appropriate to do so. In addition, the Fund may enter into
transactions to sell its purchase commitments to third parties at current
market values and simultaneously acquire other commitments to purchase
similar securities at later dates. The Fund may realize short-term profits
or losses upon the sale of such commitments.

RESTRICTED AND ILLIQUID SECURITIES

The Fund may invest in restricted securities, and, as a matter of
fundamental investment policy which cannot be changed without shareholder
approval, will limit such investments to 10% of its net assets. This
restriction is not applicable to restricted securities determined to be
liquid under criteria established by the Trustees. Restricted securities are
any securities in which the Fund may invest pursuant to its investment
objective and policies but which are subject to restrictions on resale under
federal securities law. As a matter of non-fundamental investment policy,
the Fund will limit investments in illiquid securities, including restricted
securities not determined to be liquid, and non-negotiable time deposits, to
10% of its net assets.

TEMPORARY INVESTMENTS

From time to time, when the investment adviser determines that market
conditions call for a temporary defensive posture, the Fund may invest in
tax-exempt or taxable securities, all of comparable quality to other
securities in which the Fund invests, such as: obligations issued by or on
behalf of municipal or corporate issuers; obligations issued or guaranteed
by the U.S. government, its agencies, or instrumentalities; instruments
issued by a U.S. branch of a domestic bank or other deposit institutions
having capital, surplus, and undivided profits in excess of $100,000,000 at
the time of investment; and repurchase agreements (arrangements in which the
organization selling the Fund a temporary investment agrees at the time of
sale to repurchase it at a mutually agreed upon time and price).

Although the Fund is permitted to make taxable, temporary investments, there
is no current intention to do so. However, the interest from certain
Municipal Securities is subject to the federal alternative minimum tax.

MUNICIPAL SECURITIES

Municipal Securities are generally issued to finance public works, such as
airports, bridges, highways, housing, hospitals, mass transportation
projects, schools, streets, and water and sewer works. They are also issued
to repay outstanding obligations, to raise funds for general operating
expenses, and to make loans to other public institutions and facilities.

Municipal Securities include industrial development bonds issued by or on
behalf of public authorities to provide financing aid to acquire sites or
construct and equip facilities for privately or publicly owned corporations.
The availability of this financing encourages these corporations to locate
within the sponsoring communities and thereby increases local employment.

The two principal classifications of Municipal Securities are "general
obligation" and "revenue" bonds. General obligation bonds are secured by the
issuer's pledge of its full faith and credit and taxing power for the
payment of principal and interest. Interest on and principal of revenue
bonds, however, are payable only from the revenue generated by the facility
financed by the bond or other specified sources of revenue. Revenue bonds do
not represent a pledge of credit or create any debt of or charge against the
general revenues of a municipality or public authority. Industrial
development bonds are typically classified as revenue bonds.

INVESTMENT RISKS

Yields on Municipal Securities depend on a variety of factors, including:
the general conditions of the short-term municipal note market and of the
municipal bond market; the size of the particular offering; the maturity of
the obligations; and the rating of the issue. The ability of the Fund to
achieve its investment objective also depends on the continuing ability of
the issuers of Municipal Securities and participation interests, or the
credit enhancers of either, to meet their obligations for the payment of
interest and principal when due. In addition, from time to time, the supply
of Municipal Securities acceptable for purchase by the Fund could become
limited.

The Fund may invest in Municipal Securities which are repayable out of
revenue streams generated from economically related projects or facilities
and/or whose issuers are located in the same state. Sizable investments in
these Municipal Securities could involve an increased risk to the Fund
should any of these related projects or facilities experience financial
difficulties.

Obligations of issuers of Municipal Securities are subject to the provisions
of bankruptcy, insolvency, and other laws affecting the rights and remedies
of creditors. In addition, the obligations of such issuers may become
subject to laws enacted in the future by Congress, state legislators, or
referenda extending the time for payment of principal and/or interest, or
imposing other constraints upon enforcement of such obligations or upon the
ability of states or municipalities to levy taxes. There is also the
possibility that, as a result of litigation or other conditions, the power
or ability of any issuer to pay, when due, the principal of and interest on
its municipal securities may be materially affected. The Fund's
concentration in Municipal Securities may entail a greater level of risk
than other types of money market funds.

INVESTMENT LIMITATIONS

The Fund will not borrow money or pledge securities except, under certain
circumstances, the Fund may borrow up to one-third of the value of its total
assets and pledge up to 15% of the value of these assets to secure such
borrowings. These investment limitations cannot be changed without
shareholder approval.

FUND INFORMATION

MANAGEMENT OF THE FUND

BOARD OF TRUSTEES

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

INVESTMENT ADVISER

Investment decisions for the Fund are made by Federated Management, the
Fund's investment adviser, subject to direction by the Trustees. The adviser
continually conducts investment research and supervision for the Fund and is
responsible for the purchase and sale of portfolio instruments.

ADVISORY FEES

The adviser receives an annual investment advisory fee equal to 0.20% of the
Fund's average daily net assets. The adviser may voluntarily choose to waive
a portion of its fee or reimburse other expenses of the Fund, but reserves
the right to terminate such waiver or reimbursement at any time at its sole
discretion.

ADVISER'S BACKGROUND

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

Federated Management and other subsidiaries of Federated Investors serve as
investment advisers to a number of investment companies and private
accounts. Certain other subsidiaries also provide administrative services to
a number of investment companies. With over $110 billion invested across
over 300 funds under management and/or administration by its subsidiaries,
as of December 31, 1996, Federated Investors is one of the largest mutual
fund investment managers in the United States. With more than 2,000
employees, Federated continues to be led by the management who founded the
company in 1955. Federated funds are presently at work in and through 4,500
financial institutions nationwide.

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

DISTRIBUTION OF INSTITUTIONAL SHARES

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

SHAREHOLDER SERVICES

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

SUPPLEMENTAL PAYMENTS TO FINANCIAL INSTITUTIONS

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

ADMINISTRATION OF THE FUND

ADMINISTRATIVE SERVICES

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

 MAXIMUM         AVERAGE AGGREGATE
   FEE            DAILY NET ASSETS
 0.150%      on the first $250 million
 0.125%       on the next $250 million
 0.100%       on the next $250 million
 0.075% on assets in excess of $750 million

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

NET ASSET VALUE

The Fund attempts to stabilize the net asset value of shares at $1.00 by
valuing the portfolio securities using the amortized cost method. The net
asset value per share is determined by subtracting liabilities attributable
to Institutional Shares from the value of Fund assets attributable to
Institutional Shares, and dividing the remainder by the number of
Institutional Shares outstanding. The Fund cannot guarantee that its net
asset value will always remain at $1.00 per share.

The net asset value is determined at 12:00 noon, 3:00 p.m. (Eastern time),
and as of the close of trading (normally 4:00 p.m., Eastern time) on the New
York Stock Exchange, Monday through Friday, except on New Year's Day, Martin
Luther King Day, Presidents' Day, Good Friday, Memorial Day, Independence
Day, Labor Day, Thanksgiving Day, and Christmas Day.

HOW TO PURCHASE SHARES

Shares are sold at their net asset value, without a sales charge, next
determined after an order is received, on days on which the New York Stock
Exchange is open for business. Shares may be purchased either by wire or by
check. The Fund reserves the right to reject any purchase request.

To make a purchase, open an account by calling Federated Securities Corp.
Information needed to establish the account will be taken by telephone. The
minimum initial investment is $1,000,000. However, an account may be opened
with a smaller amount as long as the minimum is reached within one year of
opening the account. Financial institutions may impose different minimum
investment requirements on their customers.

PURCHASING SHARES BY WIRE

Shares may be purchased by Federal Reserve wire by calling the Fund before
3:00 p.m. (Eastern time) to place an order. The order is considered received
immediately. Payment by federal funds must be received before 3:00 p.m.
(Eastern time) that day. Federal funds should be wired as follows: Federated
Shareholder Services Company, c/o State Street Bank and Trust Company,
Boston, MA; Attention: EDGEWIRE; For Credit to: Tax-Free Obligations
Fund--Institutional Shares; Fund Number (this number can be found on the
account statement or by contacting the Fund); Group Number or Order Number;
Nominee or Institution Name; and ABA Number 011000028. Shares cannot be
purchased by wire on holidays when wire transfers are restricted. Questions
on wire purchases should be directed to your shareholder services
representative at the telephone number listed on your account statement.

PURCHASING SHARES BY CHECK

Shares may be purchased by sending a check to Federated Shareholder Services
Company, P.O. Box 8600, Boston, MA 02266-8600. The check should be made
payable to: Tax-Free Obligations Fund--Institutional Shares. 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.

INVEST-BY-PHONE

Once an account has been opened, a shareholder may use invest-by-phone for
investments if an authorization form has been filed with Federated
Shareholder Services Company, the transfer agent for shares of the Fund.
Approximately two weeks after sending the form to Federated Shareholder
Services Company, the shareholder may call Federated Shareholder Services
Company to purchase shares. Federated Shareholder Services Company will send
a request for monies to the shareholder's commercial bank, savings bank, or
credit union ("bank") via the Automated Clearing House. The shareholder's
bank, which must be an Automated Clearing House member, will then forward
the monies to Federated Shareholder Services Company. The purchase is
normally entered the next business day after the initial phone request. For
further information and an application, call the Fund.

HOW TO REDEEM SHARES

Shares are redeemed at their net asset value next determined after Federated
Shareholder Services Company receives the redemption request. Redemptions
will be made on days on which the Fund computes its net asset value.
Redemption requests must be received in proper form and can be made as
described below.

REDEEMING SHARES BY TELEPHONE

Redemptions in any amount may be made by calling the Fund provided the Fund
has a properly completed authorization form. These forms can be obtained
from Federated Securities Corp. Proceeds from redemption requests received
before 12:00 noon (Eastern time) will be wired the same day to the
shareholder's account at a domestic commercial bank which is a member of the
Federal Reserve System, but will not include that day's dividend. Proceeds
from redemption requests received after that time include that day's
dividend but will be wired the following business day. Proceeds from
redemption requests on holidays when wire transfers are restricted will be
wired the following business day. Questions about telephone redemptions on
days when wire transfers are restricted should be directed to your
shareholder services representative at the telephone number listed on your
account statement.

Telephone instructions may be recorded and if reasonable procedures are not
followed by the Fund, it may be liable for losses due to unauthorized or
fraudulent telephone instructions.

In the event of drastic economic or market changes, a shareholder may
experience difficulty in redeeming by telephone. If this occurs, "Redeeming
Shares by Mail" should be considered. If at any time the Fund shall
determine it necessary to terminate or modify the telephone redemption
privilege, shareholders would be promptly notified.

REDEEMING SHARES BY MAIL

Shares may be redeemed in any amount by mailing a written request to:
Federated Shareholder Services Company, P.O. Box 8600, Boston, MA
02266-8600. If share certificates have been issued, they should be sent
unendorsed with the written request by registered or certified mail to the
address noted above.

The written request should state: the Fund name and the class designation;
the account name as registered with the Fund; the account number; and the
number of shares to be redeemed or the dollar amount requested. All owners
of the account must sign the request exactly as the shares are registered.
Normally, a check for the proceeds is mailed within one business day, but in
no event more than seven days, after the receipt of a proper written
redemption request. Dividends are paid up to and including the day that a
redemption request is processed.

Shareholders requesting a redemption of any amount to be sent to an address
other than that on record with the Fund or a redemption payable other than
to the shareholder of record must have their signatures guaranteed by a
commercial or savings bank, trust company or savings association whose
deposits are insured by an organization which is administered by the Federal
Deposit Insurance Corporation; a member firm of a domestic stock exchange;
or any other "eligible guarantor institution," as defined in the Securities
Exchange Act of 1934. The Fund does not accept signatures guaranteed by a
notary public.

ACCOUNT AND SHARE INFORMATION

DIVIDENDS

Dividends are declared daily and paid monthly. Dividends are automatically
reinvested on payment dates in additional shares of the Fund unless cash
payments are requested by writing to the Fund. Shares purchased by wire
before 3:00 p.m. (Eastern time) begin earning dividends that day. Shares
purchased by check begin earning dividends the day after the check is
converted into federal funds.

CAPITAL GAINS

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 will distribute in cash or additional shares any
realized net long-term capital gains at least once every 12 months.

CONFIRMATIONS AND ACCOUNT STATEMENTS

Shareholders will receive detailed confirmations of transactions (except for
systematic program transactions). In addition, shareholders will receive
periodic statements reporting all account activity, including dividends
paid. The Fund will not issue share certificates.

ACCOUNTS WITH LOW BALANCES

Due to the high cost of maintaining accounts with low balances, the Fund may
redeem shares in any account and pay the proceeds to the shareholder if the
account balance falls below a required minimum value of $1,000,000 due to
shareholder redemptions. Before shares are redeemed to close an account, the
shareholder is notified in writing and allowed 30 days to purchase
additional shares to meet the minimum requirement.

VOTING RIGHTS

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

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

TAX INFORMATION

FEDERAL INCOME TAX

The Fund will pay no federal income tax because it expects to meet
requirements of the Internal Revenue Code applicable to regulated investment
companies and to receive the special tax treatment afforded to such
companies. The Fund will be treated as a single, separate entity for federal
income tax purposes so that income (including capital gains) and losses
realized by the Trust's other portfolios will not be combined for tax
purposes with those realized by the Fund.

Shareholders are not required to pay the federal regular income tax on any
dividends received from the Fund that represent net interest on tax-exempt
municipal bonds. However, under the Tax Reform Act of 1986, dividends
representing net interest earned on certain "private activity" bonds issued
after August 7, 1986, may be included in calculating the federal individual
alternative minimum tax or the federal alternative minimum tax for
corporations. The Fund may purchase, within the limits of its investment
policies, all types of municipal bonds, including private activity bonds.

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

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

These tax consequences apply whether dividends are received in cash or as
additional shares.

STATE AND LOCAL TAXES

In the opinion of Houston, Donnelly & Meck, counsel to the Trust, Fund
shares may be subject to personal property taxes imposed by counties,
municipalities, and school districts in Pennsylvania to the extent that the
portfolio securities in the Fund would be subject to such taxes if owned
directly by residents of those jurisdictions.

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

OTHER CLASSES OF SHARES

The Fund also offers other classes. Institutional Service Shares are sold at
net asset value primarily to financial institutions, financial
intermediaries and institutional investors and are subject to a minimum
initial investment of $1,000,000.

All classes are subject to certain of the same expenses.

Institutional Service Shares are distributed with no 12b-1 Plan but are
subject to shareholder services fees.

Expense differences between classes may affect the performance of each
class.

To obtain more information and a prospectus for any other class, investors
may call 1-800-341-7400.

PERFORMANCE INFORMATION

From time to time, the Fund advertises its yield, effective yield,
tax-equivalent yield, and total return. The performance figures will be
calculated separately for each class of shares.

Yield represents the annualized rate of income earned on an investment over
a seven-day period. It is the annualized dividends earned during the period
on an investment shown as a percentage of the investment. The effective
yield is calculated similarly to the yield, but when annualized, the income
earned by an investment is assumed to be reinvested daily. The effective
yield will be slightly higher than the yield because of the compounding
effect of this assumed reinvestment. The tax-equivalent yield is calculated
similarly to the yield, but is adjusted to reflect the taxable yield that
would have to be earned to equal the Fund's tax-exempt yield, assuming a
specific tax rate.

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

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

(a) The Fund may only invest in securities rated in one of the two highest
short-term rating categories by nationally recognized statistical rating
organizations ("NRSROs") or unrated securities of comparable quality. An
NRSRO's two highest rating categories are determined without regard for
sub-categories and gradations. For example, securities rated SP-1+, SP-1 or
SP-2 by Standard & Poor's Corporation, MIG-1, or MIG-2 by Moody's Investors
Service, Inc., F-1+, F-1, and F-2 by Fitch Investors Service, Inc. are all
considered rated in one of the two highest short-term rating categories.

Securities rated in the highest short-term rating category (and unrated
securities of comparable quality) are identified as First Tier securities.
Securities rated in the second highest short-term rating category (and
unrated securities of comparable quality) are identified as Second Tier
securities. The Fund follows applicable regulations in determining whether a
security is rated and whether a security rated by multiple NRSROs in
different rating categories should be identified as a First or Second Tier
security.

At July 31 1997, the portfolio securities were rated as follows:

Tier Rating Percent Based on Total Market Value (Unaudited)

 FIRST TIER   SECOND TIER
   100.00%       0.00%
(b) Denotes a restricted security which is subject to restrictions on resale
under Federal Securities laws. At July 31, 1997, these securities amounted
to $9,360,000 which represents 0.5% of net assets.

(c) Cost for federal tax purposes $2,054,030,605.

Note: The categories of investments are shown as a percentage of net assets
($2,062,163,006) at July 31, 1997.

NOTES TO FINANCIAL STATEMENTS

TAX-FREE OBLIGATIONS FUND

JULY 31, 1997

ORGANIZATION

Money Market Obligations Trust (the "Trust") is registered under the
Investment Company Act of 1940, as amended (the "Act") as an open-end,
management investment company. The Trust consists of six portfolios. The
financial statements included herein are only those of Tax-Free Obligations
Fund (the "Fund"). The financial statements of the other portfolios are
presented separately. The assets of each portfolio are segregated and a
shareholder's interest is limited to the portfolio in which shares are held.
The investment objective of the Fund is to provide dividend income exempt
from federal regular income tax consistent with stability of principal.

The Fund offers two classes of shares: Institutional Shares and
Institutional Service Shares.

SIGNIFICANT ACCOUNTING POLICIES

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

INVESTMENT VALUATIONS

The Fund uses the amortized cost method to value its portfolio securities in
accordance with Rule 2a-7 under the Act.

INVESTMENT INCOME, EXPENSES AND DISTRIBUTIONS

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

Income and capital gain distributions are determined in accordance with
income tax regulations which may differ from generally accepted accounting
principles. These differences are primarily due to differing book/tax
treatments of partnerships. The following reclassifications have been made
to the financial statements.

         INCREASE (DECREASE)
    UNDISTRIBUTED    ACCUMULATED
   NET INVESTMENT   NET REALIZED
       INCOME            LOSS
      $24,515         $(24,515)

Net investment income, net realized gains/losses, and net assets were not
affected by this reclassification.

FEDERAL TAXES

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

At July 31, 1997, the Fund, for federal tax purposes, had a capital loss
carryforward of $163,650, which will reduce the Fund's taxable income
arising from future net realized gain on investments, if any, to the extent
permitted by the Code, and thus will reduce the amount of the distributions
to shareholders which would otherwise be necessary to relieve the Fund of
any liability for federal tax. Pursuant to the Code, such capital loss
carryforward will expire as follows:

 EXPIRATION YEAR        EXPIRATION AMOUNT
           2001              $580
           2002            19,220
           2004            36,269
           2005           107,581

Additionally, net capital losses of $16,488 attributable to security
transactions incurred after October 31, 1996, are treated as arising on the
first day of the Fund's next taxable year.

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

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

RESTRICTED SECURITIES

Restricted securities are securities that may only be resold upon
restoration under federal securities laws or in transactions exempt from
such registration. Many restricted securities may be resold in the secondary
market in transactions exempt from registration upon exercise or a demand
feature. Such restricted securities may be determined to be liquid under
criteria established by the Board of Directors. The Fund will not incur any
registration costs upon such resales. Restricted securities are valued at
amortized cost in accordance with Rule 2a-7 under the Investment Company Act
of 1940.

Additional information on the restricted security held at July 31, 1997, is
as follows:

 SECURITY                             ACQUISITION DATE   ACQUISITION COST
 Delaware County, PA (Series 1993G)       12/2/1996         $9,360,000

USE OF ESTIMATES

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

OTHER

Investment transactions are accounted for on the trade date.

SHARES OF BENEFICIAL INTEREST

The Declaration of Trust permits the Trustees to issue an unlimited number
of full and fractional shares of beneficial interest (without par value) for
each class of shares. At July 31, 1997, capital paid-in aggregated
$2,062,261,061.

Transactions in shares were as follows:

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Shareholders and Board of Trustees of MONEY MARKET OBLIGATIONS TRUST
(Tax-Free Obligations Fund):

We have audited the accompanying statement of assets and liabilities of
Tax-Free Obligations Fund (an investment portfolio of Money Market
Obligations Trust, a Massachusetts business trust), including the schedule
of portfolio investments, as of July 31, 1997, the related statement of
operations for the year then ended, the statement of changes in net assets
for each of the two years in the period then ended, and the financial
highlights for the periods presented. These financial statements and
financial highlights are the responsibility of the Trust's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements and
financial highlights are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures
in the financial statements. Our procedures included confirmation of
securities owned as of July 31, 1997, by correspondence with the custodian.
An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of
Tax-Free Obligations Fund (an investment portfolio of Money Market
Obligations Trust) as of July 31, 1997, the results of its operations for
the year then ended, the changes in its net assets for each of the two years
in the period then ended, and its financial highlights for the periods
presented, in conformity with generally accepted accounting principles.

GENERAL INFORMATION

The Trust was established as a Massachusetts business trust under a
Declaration of Trust dated October 3, 1988. The Declaration of Trust permits
the Trust to offer separate series of shares representing interests in
separate portfolios of securities. The shares in any one portfolio may be
offered in separate classes. With respect to this Fund, as of the date of
this prospectus, the Board of Trustees (the "Trustees") has established two
classes of shares known as Institutional Service Shares and Institutional
Shares. This prospectus relates only to Institutional Service Shares of the
Fund, which are designed primarily for financial institutions, financial
intermediaries, and institutional investors as a convenient means of
accumulating an interest in a professionally managed portfolio investing
primarily in short-term municipal securities. The Fund may not be a suitable
investment for retirement plans because it invests in municipal securities.
A minimum initial investment of $1,000,000 over a one-year period is
required.

The Fund attempts to stabilize the value of a share at $1.00. Shares are
currently sold and redeemed at that price.

INVESTMENT INFORMATION

INVESTMENT OBJECTIVE

The investment objective of the Fund is to provide dividend income exempt
from federal regular income tax consistent with stability of principal. This
investment objective cannot be changed without shareholder approval. While
there is no assurance that the Fund will achieve its investment objective,
it endeavors to do so by complying with the diversification and other
requirements of Rule 2a-7 under the Investment Company Act of 1940 which
regulates money market mutual funds and by following the investment policies
described in this prospectus.

INVESTMENT POLICIES

The Fund pursues its investment objective by investing in a portfolio of
municipal securities maturing in 13 months or less. The average maturity of
the securities in the Fund's portfolio, computed on a dollar-weighted basis,
will be 90 days or less. As a matter of investment policy, which cannot be
changed without shareholder approval, at least 80% of the Fund's annual
interest income will be exempt from federal regular income tax. (Federal
regular income tax does not include the federal individual alternative
minimum tax or the federal alternative minimum tax for corporations.) Unless
indicated otherwise, the investment policies may be changed by the Trustees
without shareholder approval. Shareholders will be notified before any
material change in these policies becomes effective.

ACCEPTABLE INVESTMENTS

The Fund invests primarily in debt obligations issued by or on behalf of
states, territories, and possessions of the United States, including the
District of Columbia, and any political subdivision or financing authority
of any of these, the income from which is, in the opinion of qualified legal
counsel, exempt from federal regular income tax ("Municipal Securities").
Examples of Municipal Securities include, but are not limited to:

   * tax and revenue anticipation notes issued to finance working capital
     needs in anticipation of receiving taxes or other revenues;
   * bond anticipation notes that are intended to be refinanced through a
     later issuance of longer-term bonds;
   * municipal commercial paper and other short-term notes;
   * variable rate demand notes;
   * municipal bonds (including bonds having serial maturities and
     pre-refunded bonds) and leases; and
   * participation, trust, and partnership interests in any of the foregoing
     obligations.

VARIABLE RATE DEMAND NOTES

Variable rate demand notes are long-term debt instruments that have variable
or floating interest rates and provide the Fund with the right to tender the
security for repurchase at its stated principal amount plus accrued
interest. Such securities typically bear interest at a rate that is intended
to cause the securities to trade at par. The interest rate may float or be
adjusted at regular intervals (ranging from daily to annually), and is
normally based on a published interest rate or interest rate index. Most
variable rate demand notes allow the Fund to demand the repurchase of the
security on not more than seven days prior notice. Other notes only permit
the Fund to tender the security at the time of each interest rate adjustment
or at other fixed intervals. See "Demand Features." The Fund treats variable
rate demand notes as maturing on the later of the date of the next interest
rate adjustment or the date on which the Fund may next tender the security
for repurchase.

PARTICIPATION INTERESTS

The Fund may purchase interests in Municipal Securities from financial
institutions such as commercial and investment banks, savings associations,
and insurance companies. These interests may take the form of
participations, beneficial interests in a trust, partnership interests or
any other form of indirect ownership that allows the Fund to treat the
income from the investment as exempt from federal income tax. The Fund
invests in these participation interests in order to obtain credit
enhancement or demand features that would not be available through direct
ownership of the underlying Municipal Securities.

MUNICIPAL LEASES

Municipal leases are obligations issued by state and local governments or
authorities to finance the acquisition of equipment and facilities. They may
take the form of a lease, an installment purchase contract, a conditional
sales contract, or a participation interest in any of the above. Lease
obligations may be subject to periodic appropriation. Municipal leases are
subject to certain specific risks in the event of default or failure of
appropriation.

CREDIT ENHANCEMENT

Certain of the Fund's acceptable investments may be credit-enhanced by a
guaranty, letter of credit, or insurance. Any bankruptcy, receivership,
default, or change in the credit quality of the party providing the credit
enhancement will adversely affect the quality and marketability of the
underlying security and could cause losses to the Fund and affect its share
price. The Fund may have more than 25% of its total assets invested in
securities credit-enhanced by banks.

DEMAND FEATURES

The Fund may acquire securities that are subject to puts and standby
commitments ("demand features") to purchase the securities at their
principal amount (usually with accrued interest) within a fixed period
(usually seven days) following a demand by the Fund. The demand feature may
be issued by the issuer of the underlying securities, a dealer in the
securities, or by another third party, and may not be transferred separately
from the underlying security. The Fund uses these arrangements to provide
the Fund with liquidity and not to protect against changes in the market
value of the underlying securities. The bankruptcy, receivership, or default
by the issuer of the demand feature, or a default on the underlying security
or other event that terminates the demand feature before its exercise, will
adversely affect the liquidity of the underlying security. Demand features
that are exercisable even after a payment default on the underlying security
may be treated as a form of credit enhancement.

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

The Fund may purchase securities on a when-issued or delayed delivery basis.
These transactions are arrangements in which the Fund purchases securities
with payment and delivery scheduled for a future time. The seller's failure
to complete these transactions may cause the Fund to miss a price or yield
considered to be advantageous. Settlement dates may be a month or more after
entering into these transactions, and the market values of the securities
purchased may vary from the purchase prices.

The Fund may dispose of a commitment prior to settlement if the adviser
deems it appropriate to do so. In addition, the Fund may enter into
transactions to sell its purchase commitments to third parties at current
market values and simultaneously acquire other commitments to purchase
similar securities at later dates. The Fund may realize short-term profits
or losses upon the sale of such commitments.

RESTRICTED AND ILLIQUID SECURITIES

The Fund may invest in restricted securities, and, as a matter of
fundamental investment policy which cannot be changed without shareholder
approval, will limit such investments to 10% of its net assets. This
restriction is not applicable to restricted securities determined to be
liquid under criteria established by the Trustees. Restricted securities are
any securities in which the Fund may invest pursuant to its investment
objective and policies but which are subject to restrictions on resale under
federal securities law. As a matter of non-fundamental investment policy,
the Fund will limit investments in illiquid securities including restricted
securities not determined to be liquid, and non-negotiable time deposits, to
10% of its net assets.

TEMPORARY INVESTMENTS

From time to time, when the investment adviser determines that market
conditions call for a temporary defensive posture, the Fund may invest in
tax-exempt or taxable securities, all of comparable quality to other
securities in which the Fund invests, such as: obligations issued by or on
behalf of municipal or corporate issuers; obligations issued or guaranteed
by the U.S. government, its agencies, or instrumentalities; instruments
issued by a U.S. branch of a domestic bank or other deposit institutions
having capital, surplus, and undivided profits in excess of $100,000,000 at
the time of investment; and repurchase agreements (arrangements in which the
organization selling the Fund a temporary investment agrees at the time of
sale to repurchase it at a mutually agreed upon time and price).

Although the Fund is permitted to make taxable, temporary investments, there
is no current intention to do so. However, the interest from certain
Municipal Securities is subject to the federal alternative minimum tax.

MUNICIPAL SECURITIES

Municipal Securities are generally issued to finance public works, such as
airports, bridges, highways, housing, hospitals, mass transportation
projects, schools, streets, and water and sewer works. They are also issued
to repay outstanding obligations, to raise funds for general operating
expenses, and to make loans to other public institutions and facilities.

Municipal Securities include industrial development bonds issued by or on
behalf of public authorities to provide financing aid to acquire sites or
construct and equip facilities for privately or publicly owned corporations.
The availability of this financing encourages these corporations to locate
within the sponsoring communities and thereby increases local employment.

The two principal classifications of Municipal Securities are "general
obligation" and "revenue" bonds. General obligation bonds are secured by the
issuer's pledge of its full faith and credit and taxing power for the
payment of principal and interest. Interest on and principal of revenue
bonds, however, are payable only from the revenue generated by the facility
financed by the bond or other specified sources of revenue. Revenue bonds do
not represent a pledge of credit or create any debt of or charge against the
general revenues of a municipality or public authority. Industrial
development bonds are typically classified as revenue bonds.

INVESTMENT RISKS

Yields on Municipal Securities depend on a variety of factors, including:
the general conditions of the short-term municipal note market and of the
municipal bond market; the size of the particular offering; the maturity of
the obligations; and the rating of the issue. The ability of the Fund to
achieve its investment objective also depends on the continuing ability of
the issuers of Municipal Securities and participation interests, or the
credit enhancers of either, to meet their obligations for the payment of
interest and principal when due. In addition, from time to time, the supply
of Municipal Securities acceptable for purchase by the Fund could become
limited.

The Fund may invest in Municipal Securities which are repayable out of
revenue streams generated from economically related projects or facilities
and/or whose issuers are located in the same state. Sizable investments in
these Municipal Securities could involve an increased risk to the Fund
should any of these related projects or facilities experience financial
difficulties.

Obligations of issuers of Municipal Securities are subject to the provisions
of bankruptcy, insolvency, and other laws affecting the rights and remedies
of creditors. In addition, the obligations of such issuers may become
subject to laws enacted in the future by Congress, state legislators, or
referenda extending the time for payment of principal and/or interest, or
imposing other constraints upon enforcement of such obligations or upon the
ability of states or municipalities to levy taxes. There is also the
possibility that, as a result of litigation or other conditions, the power
or ability of any issuer to pay, when due, the principal of and interest on
its municipal securities may be materially affected. The Fund's
concentration in Municipal Securities may entail a greater level of risk
than other types of money market funds.

INVESTMENT LIMITATIONS

The Fund will not borrow money or pledge securities except, under certain
circumstances, the Fund may borrow up to one-third of the value of its total
assets and pledge up to 15% of the value of those assets to secure such
borrowings. These investment limitations cannot be changed without
shareholder approval.

FUND INFORMATION

MANAGEMENT OF THE FUND

BOARD OF TRUSTEES

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

INVESTMENT ADVISER

Investment decisions for the Fund are made by Federated Management, the
Fund's investment adviser, subject to direction by the Trustees. The adviser
continually conducts investment research and supervision for the Fund and is
responsible for the purchase and sale of portfolio instruments.

Advisory Fees

The adviser receives an annual investment advisory fee equal to 0.20% of the
Fund's average daily net assets. The adviser may voluntarily choose to waive
a portion of its fee or reimburse other expenses of the Fund, but reserves
the right to terminate such waiver or reimbursement at any time at its sole
discretion.

Adviser's Background

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

Federated Management and other subsidiaries of Federated Investors serve as
investment advisers to a number of investment companies and private
accounts. Certain other subsidiaries also provide administrative services to
a number of investment companies. With over $110 billion invested across
over 300 funds under management and/or administration by its subsidiaries,
as of December 31, 1996, Federated Investors is one of the largest mutual
fund investment managers in the United States. With more than 2,000
employees, Federated continues to be led by the management who founded the
company in 1955. Federated funds are presently at work in and through 4,500
financial institutions nationwide.

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

DISTRIBUTION OF INSTITUTIONAL SERVICE SHARES

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

SHAREHOLDER SERVICES

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

SUPPLEMENTAL PAYMENTS TO FINANCIAL INSTITUTIONS

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

ADMINISTRATION OF THE FUND

ADMINISTRATIVE SERVICES

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

 MAXIMUM            AVERAGE AGGREGATE
   FEE               DAILY NET ASSETS
 0.150%         on the first $250 million
 0.125%          on the next $250 million
 0.100%          on the next $250 million
 0.075%    on assets in excess of $750 million
The administrative fee received during any fiscal year shall be at least
$125,000 per portfolio and $30,000 per each additional class of shares.
Federated Services Company may choose voluntarily to waive a portion of its
fee.

NET ASSET VALUE

The Fund attempts to stabilize the net asset value of shares at $1.00 by
valuing the portfolio securities using the amortized cost method. The net
asset value per share is determined by subtracting liabilities attributable
to Institutional Service Shares from the value of Fund assets attributable
to Institutional Service Shares, and dividing the remainder by the number of
Institutional Service Shares outstanding. The Fund cannot guarantee that its
net asset value will always remain at $1.00 per share.

The net asset value is determined at 12:00 noon, 3:00 p.m. (Eastern time),
and as of the close of trading (normally 4:00 p.m., Eastern time) on the New
York Stock Exchange, Monday through Friday, except on New Year's Day, Martin
Luther King Day, Presidents' Day, Good Friday, Memorial Day, Independence
Day, Labor Day, Thanksgiving Day, and Christmas Day.

HOW TO PURCHASE SHARES

Shares are sold at their net asset value, without a sales charge, next
determined after an order is received, on days on which the New York Stock
Exchange is open for business. Shares may be purchased either by wire or by
check. The Fund reserves the right to reject any purchase request.

To make a purchase, open an account by calling Federated Securities Corp.
Information needed to establish the account will be taken by telephone. The
minimum initial investment is $1,000,000. However, an account may be opened
with a smaller amount as long as the minimum is reached within one year of
opening the account. Financial institutions may impose different minimum
investment requirements on their customers.

PURCHASING SHARES BY WIRE

Shares may be purchased by Federal Reserve wire by calling the Fund before
3:00 p.m. (Eastern time) to place an order. The order is considered received
immediately. Payment by federal funds must be received before 3:00 p.m.
(Eastern time) that day. Federal funds should be wired as follows: Federated
Shareholder Services Company, c/o State Street Bank and Trust Company,
Boston, MA; Attention: EDGEWIRE; For Credit to: Tax-Free Obligations Fund --
Institutional Service Shares; Fund Number (this number can be found on the
account statement or by contacting the Fund); Group Number or Order Number;
Nominee or Institution Name; and ABA Number 011000028. Shares cannot be
purchased by wire on holidays when wire transfers are restricted. Questions
on wire purchases should be directed to your shareholder services
representative at the telephone number listed on your account statement.

PURCHASING SHARES BY CHECK

Shares may be purchased by sending a check to Federated Shareholder Services
Company, P.O. Box 8600, Boston, MA 02266-8600. The check should be made
payable to: Tax-Free Obligations Fund -- Institutional Service Shares.
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.

INVEST-BY-PHONE

Once an account has been opened, a shareholder may use invest-by-phone for
investments if an authorization form has been filed with Federated
Shareholder Services Company, the transfer agent for shares of the Fund.
Approximately two weeks after sending the form to Federated Shareholder
Services Company, the shareholder may call Federated Shareholder Services
Company to purchase shares. Federated Shareholder Services Company will send
a request for monies to the shareholder's commercial bank, savings bank, or
credit union ("bank") via the Automated Clearing House. The shareholder's
bank, which must be an Automated Clearing House member, will then forward
the monies to Federated Shareholder Services Company. The purchase is
normally entered the next business day after the initial phone request. For
further information and an application, call the Fund.

HOW TO REDEEM SHARES

Shares are redeemed at their net asset value next determined after Federated
Shareholder Services Company receives the redemption request. Redemptions
will be made on days on which the Fund computes its net asset value.
Redemption requests must be received in proper form and can be made as
described below.

REDEEMING SHARES BY TELEPHONE

Redemptions in any amount may be made by calling the Fund provided the Fund
has a properly completed authorization form. These forms can be obtained
from Federated Securities Corp. Proceeds from redemption requests received
before 12:00 noon (Eastern time) will be wired the same day to the
shareholder's account at a domestic commercial bank which is a member of the
Federal Reserve System, but will not include that day's dividend. Proceeds
from redemption requests received after that time include that day's
dividend but will be wired the following business day. Proceeds from
redemption requests on holidays when wire transfers are restricted will be
wired the following business day. Questions about telephone redemptions on
days when wire transfers are restricted should be directed to your
shareholder services representative at the telephone number listed on your
account statement.

Telephone instructions may be recorded and if reasonable procedures are not
followed by the Fund, it may be liable for losses due to unauthorized or
fraudulent telephone instructions.

In the event of drastic economic or market changes, a shareholder may
experience difficulty in redeeming by telephone. If this occurs, "Redeeming
Shares By Mail" should be considered. If at any time the Fund shall
determine it necessary to terminate or modify the telephone redemption
privilege, shareholders would be promptly notified.

REDEEMING SHARES BY MAIL

Shares may be redeemed in any amount by mailing a written request to:
Federated Shareholder Services Company, P.O. Box 8600, Boston, MA
02266-8600. If share certificates have been issued, they should be sent
unendorsed with the written request by registered or certified mail to the
address noted above.

The written request should state: the Fund name and the class designation;
the account name as registered with the Fund; the account number; and the
number of shares to be redeemed or the dollar amount requested. All owners
of the account must sign the request exactly as the shares are registered.
Normally, a check for the proceeds is mailed within one business day, but in
no event more than seven days, after the receipt of a proper written
redemption request. Dividends are paid up to and including the day that a
redemption request is processed.

Shareholders requesting a redemption of any amount to be sent to an address
other than that on record with the Fund or a redemption payable other than
to the shareholder of record must have their signatures guaranteed by a
commercial or savings bank, trust company or savings association whose
deposits are insured by an organization which is administered by the Federal
Deposit Insurance Corporation; a member firm of a domestic stock exchange;
or any other "eligible guarantor institution," as defined in the Securities
Exchange Act of 1934. The Fund does not accept signatures guaranteed by a
notary public.

ACCOUNT AND SHARE INFORMATION

DIVIDENDS

Dividends are declared daily and paid monthly. Dividends are automatically
reinvested on payment dates in additional shares of the Fund unless cash
payments are requested by writing to the Fund. Shares purchased by wire
before 3:00 p.m. (Eastern time) begin earning dividends that day. Shares
purchased by check begin earning dividends the day after the check is
converted into federal funds.

CAPITAL GAINS

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 will distribute in cash or additional shares any
realized net long-term capital gains at least once every 12 months.

CONFIRMATIONS AND ACCOUNT STATEMENTS

Shareholders will receive detailed confirmations of transactions (except for
systematic program transactions). In addition, shareholders will receive
periodic statements reporting all account activity, including dividends
paid. The Fund will not issue share certificates.

ACCOUNTS WITH LOW BALANCES

Due to the high cost of maintaining accounts with low balances, the Fund may
redeem shares in any account and pay the proceeds to the shareholder if the
account balance falls below a required minimum value of $1,000,000 due to
shareholder redemptions. Before shares are redeemed to close an account, the
shareholder is notified in writing and allowed 30 days to purchase
additional shares to meet the minimum requirement.

VOTING RIGHTS

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

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

TAX INFORMATION

FEDERAL INCOME TAX

The Fund will pay no federal income tax because it expects to meet
requirements of the Internal Revenue Code applicable to regulated investment
companies and to receive the special tax treatment afforded to such
companies. The Fund will be treated as a single, separate entity for federal
income tax purposes so that income (including capital gains) and losses
realized by the Trust's other portfolios will not be combined for tax
purposes with those realized by the Fund.

Shareholders are not required to pay the federal regular income tax on any
dividends received from the Fund that represent net interest on tax-exempt
municipal bonds. However, under the Tax Reform Act of 1986, dividends
representing net interest earned on certain "private activity" bonds issued
after August 7, 1986, may be included in calculating the federal individual
alternative minimum tax or the federal alternative minimum tax for
corporations. The Fund may purchase, within the limits of its investment
policies, all types of municipal bonds, including private activity bonds.

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

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

These tax consequences apply whether dividends are received in cash or as
additional shares.

STATE AND LOCAL TAXES

In the opinion of Houston, Donnelly & Meck, counsel to the Trust, Fund
shares may be subject to personal property taxes imposed by counties,
municipalities, and school districts in Pennsylvania to the extent that the
portfolio securities in the Fund would be subject to such taxes if owned
directly by residents of those jurisdictions.

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

OTHER CLASSES OF SHARES

The Fund also offers other classes. Institutional Shares are sold at net
asset value primarily to entities holding shares in an agency or fiduciary
capacity, financial institutions, financial intermediaries, and
institutional investors and are subject to a minimum initial investment of
$1,000,000.

All classes are subject to certain of the same expenses.

Institutional Shares are distributed with no 12b-1 Plan but are subject to
shareholder services fees.

Expense differences between classes may affect the performance of each
class.

To obtain more information and a prospectus for any other class, investors
may call 1-800-341-7400.

PERFORMANCE INFORMATION

From time to time, the Fund advertises its yield, effective yield,
tax-equivalent yield, and total return. The performance figures will be
calculated separately for each class of shares.

Yield represents the annualized rate of income earned on an investment over
a seven-day period. It is the annualized dividends earned during the period
on an investment shown as a percentage of the investment. The effective
yield is calculated similarly to the yield, but when annualized, the income
earned by an investment is assumed to be reinvested daily. The effective
yield will be slightly higher than the yield because of the compounding
effect of this assumed reinvestment. The tax-equivalent yield is calculated
similarly to the yield, but is adjusted to reflect the taxable yield that
would have to be earned to equal the Fund's tax-exempt yield, assuming a
specific tax rate.

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

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

(a) The Fund may only invest in securities rated in one of the two highest
short-term rating categories by nationally recognized statistical rating
organizations ("NRSROs") or unrated securities of comparable quality. An
NRSRO's two highest rating categories are determined without regard for
sub-categories and gradations. For example, securities rated SP-1+, SP-1 or
SP-2 by Standard & Poor's Corporation, MIG-1, or MIG-2 by Moody's Investors
Service, Inc., F-1+, F-1, and F-2 by Fitch Investors Service, Inc. are all
considered rated in one of the two highest short-term rating categories.

Securities rated in the highest short-term rating category (and unrated
securities of comparable quality) are identified as First Tier securities.
Securities rated in the second highest short-term rating category (and
unrated securities of comparable quality) are identified as Second Tier
securities. The Fund follows applicable regulations in determining whether a
security is rated and whether a security rated by multiple NRSROs in
different rating categories should be identified as a First or Second Tier
security.

At July 31 1997, the portfolio securities were rated as follows:

Tier Rating Percent Based on Total Market Value (Unaudited)

 FIRST TIER   SECOND TIER
   100.00%       0.00%
(b) Denotes a restricted security which is subject to restrictions on resale
under Federal Securities laws. At July 31, 1997, these securities amounted
to $9,360,000 which represents 0.5% of net assets.

(c) Cost for federal tax purposes $2,054,030,605.

Note: The categories of investments are shown as a percentage of net assets
($2,062,163,006) at July 31, 1997.

NOTES TO FINANCIAL STATEMENTS
TAX-FREE OBLIGATIONS FUND

JULY 31, 1997

ORGANIZATION

Money Market Obligations Trust (the "Trust") is registered under the
Investment Company Act of 1940, as amended (the "Act") as an open-end,
management investment company. The Trust consists of six portfolios. The
financial statements included herein are only those of Tax-Free Obligations
Fund (the "Fund"). The financial statements of the other portfolios are
presented separately. The assets of each portfolio are segregated and a
shareholder's interest is limited to the portfolio in which shares are held.
The investment objective of the Fund is to provide dividend income exempt
from federal regular income tax consistent with the stability of principal.

The Fund offers two classes of shares: Institutional Shares and
Institutional Service Shares.

SIGNIFICANT ACCOUNTING POLICIES

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

INVESTMENT VALUATIONS

The Fund uses the amortized cost method to value its portfolio securities in
accordance with Rule 2a-7 under the Act.

INVESTMENT INCOME, EXPENSES AND DISTRIBUTIONS

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

Income and captial gain distributions are determined in accordance with
income tax regulations which may differ from generally accepted accounting
principles. These differences are primarily due to differing book/tax
treatments of partnerships. The following reclassifications have been made
to the financial statements.

        INCREASE(DECREASE)
   UNDISTRIBUTED    ACCUMULATED
   NET INVESTMENT   NET REALIZED
       INCOME          LOSS
      $24,515       $(24,515)
Net investment income, net realized gains/losses, and net assets were not
affected by this reclassification.

FEDERAL TAXES

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

At July 31, 1997, the Fund, for federal tax purposes, had a capital loss
carryforward of $163,650, which will reduce the Fund's taxable income
arising from future net realized gain on investments, if any, to the extent
permitted by the Code, and thus will reduce the amount of the distributions
to shareholders which would otherwise be necessary to relieve the Fund of
any liability for federal tax. Pursuant to the Code, such capital loss
carryforward will expire as follows:

 EXPIRATION YEAR       EXPIRATION AMOUNT
      2001                 $     580
      2002                    19,220
      2004                    36,269
      2005                   107,581
Additionally, net capital losses of $16,488 attributable to security
transactions incurred after October 31, 1996 are treated as arising on the
first day of the Fund's next taxable year.

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

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

RESTRICTED SECURITIES

Restricted securities are securities that may only be resold upon
restoration under federal securities laws or in transactions exempt from
such registration. Many restricted securities may be resold in the secondary
market in transactions exempt from registration upon exercise or a demand
feature. Such restricted securities may be determined to be liquid under
criteria established by the Board of Directors. The Fund will not incur any
registration costs upon such resales. Restricted securities are valued at
amortized cost in accordance with Rule 2a-7 under the Investment Company Act
of 1940.

Additional information on the restricted security held at July 31, 1997 is
as follows:

 SECURITY                             ACQUISITION DATE   ACQUISITION COST
 Delaware County, PA (Series 1993G)       12/2/1996         $9,360,000

USE OF ESTIMATES

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

OTHER

Investment transactions are accounted for on the trade date.

SHARES OF BENEFICIAL INTEREST

The Declaration of Trust permits the Trustees to issue an unlimited number
of full and fractional shares of beneficial interest (without par value) for
each class of shares. At July 31, 1997, capital paid-in aggregated
$2,062,261,061.

Transactions in shares were as follows:

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Shareholders and Board of Trustees of MONEY MARKET OBLIGATIONS TRUST
(Tax-Free Obligations Fund):

We have audited the accompanying statement of assets and liabilities of
Tax-Free Obligations Fund (an investment portfolio of Money Market
Obligations Trust, a Massachusetts business trust), including the schedule
of portfolio investments, as of July 31, 1997, the related statement of
operations for the year then ended, the statement of changes in net assets
for each of the two years in the period then ended, and the financial
highlights for the periods presented. These financial statements and
financial highlights are the responsibility of the Trust's management. Our
responsibility is to express an opinion on these financial statements and
financial highlights based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to
obtain reasonable assurance about whether the financial statements and
financial highlights are free of material misstatement. An audit includes
examining, on a test basis, evidence supporting the amounts and disclosures
in the financial statements. Our procedures included confirmation of
securities owned as of July 31, 1997, by correspondence with the custodian.
An audit also includes assessing the accounting principles used and
significant estimates made by management, as well as evaluating the overall
financial statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights referred
to above present fairly, in all material respects, the financial position of
Tax-Free Obligations Fund (an investment portfolio of Money Market
Obligations Trust) as of July 31, 1997, the results of its operations for
the year then ended, the changes in its net assets for each of the two years
in the period then ended, and its financial highlights for the periods
presented, in conformity with generally accepted accounting principles.

INVESTMENT POLICIES

Unless indicated otherwise, the policies described below may be
changed by the Board of Trustees (the "Trustees") without shareholder
approval. Shareholders will be notified before any material change in
these policies becomes effective.

ACCEPTABLE INVESTMENTS

When determining whether a security presents minimal credit risks, the
investment adviser will consider the creditworthiness of: the issuer
of the security; the issuer of any demand feature applicable to the
security; or any guarantor of either the security or any demand
feature.

PARTICIPATION INTERESTS

The financial institutions from which the Fund purchases participation
interests frequently provide or secure from another financial
institution irrevocable letters of credit or guarantees and give the
Fund the right to demand payment of the principal amounts of the
participation interests plus accrued interest on short notice (usually
within seven days). The municipal securities subject to the
participation interests are not limited to the Fund's maximum maturity
requirements so long as the participation interests include the right
to demand payment from the issuers of those interests. By purchasing
these participation interests, the Fund is buying a security meeting
the maturity and quality requirements of the Fund and also is
receiving the tax-free benefits of the underlying securities.

MUNICIPAL LEASES

The Fund may purchase municipal securities in the form of
participation interests that represent an undivided proportional
interest in lease payments by a governmental or nonprofit entity. The
lease payments and other rights under the lease provide for and secure
payments on the certificates. Lease obligations may be limited by
municipal charter or the nature of the appropriation for the lease.
Furthermore, a lease may provide that the participants cannot
accelerate lease obligations upon default. The participants would only
be able to enforce lease payments as they became due. In the event of
a default or failure of appropriation, unless the participation
interests are credit enhanced, it is unlikely that the participants
would be able to obtain an acceptable substitute source of payment.

In determining the liquidity of municipal lease securities, the
investment adviser, under the authority delegated by the Trustees,
will base its determination on the following factors: whether the
lease can be terminated by the lessee; the potential recovery, if any,
from a sale of the leased property upon termination of the lease; the
lessee's general credit strength (e.g., its debt, administrative,
economic and financial characteristics and prospects); the likelihood
that the lessee will discontinue appropriating funding for the leased
property because the property is no longer deemed essential to its
operations (e.g., the potential for an "event of non-appropriation");
and any credit enhancement or legal recourse provided upon an event of
non-appropriation or other termination of the lease.

RATINGS

The securities in which the Fund invests must be rated in the highest
short-term rating category by one or more nationally recognized
statistical rating organizations ("NRSROs") or be of comparable
quality to securities having such ratings. An NRSRO's highest rating
category is determined without regard for sub-categories and
gradations. For example, securities rated SP-1+ or SP-1 by Standard &
Poor's Ratings Group ("S&P"), MIG-1 by Moody's Investors Service, Inc.
("Moody's"), or F-1+ or F-1 by Fitch Investors Service, Inc. ("Fitch")
are all considered rated in the highest short-term rating category.
The Fund will follow applicable regulations in determining whether a
security rated by more than one NRSRO can be treated as being in the
highest short-term rating category; currently, such securities must be
rated by two NRSROs in their highest rating category. See "Regulatory
Compliance."

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

These transactions are made to secure what is considered to be an
advantageous price or yield for the Fund. No fees or other expenses,
other than normal transaction costs, are incurred. However, liquid
assets of the Fund in a dollar amount sufficient to make payment for
the securities to be purchased are: segregated on the Fund's records
at the trade date; marked to market daily; and maintained until the
transaction is settled. The Fund does not intend to engage in
when-issued and delayed delivery transactions to an extent that would
cause the segregation of more than 20% of the total value of its
assets.

REPURCHASE AGREEMENTS

Certain securities in which the Fund invests may be purchased pursuant
to repurchase agreements. Repurchase agreements are arrangements in
which banks, broker/dealers, and other recognized financial
institutions sell securities to the Fund and agree at the time of sale
to repurchase them at a mutually agreed upon time and price. To the
extent that the seller does not repurchase the securities from the
Fund, the Fund could receive less than the repurchase price on any
sale of such securities. The Fund or its custodian will take
possession of the securities subject to repurchase agreements, and
these securities will be marked to market daily. In the event that a
defaulting seller filed for bankruptcy or became insolvent,
disposition of such securities by the Fund might be delayed pending
court action. The Fund believes that under the regular procedures
normally in effect for custody of the Fund's portfolio securities
subject to repurchase agreements, a court of competent jurisdiction
would rule in favor of the Fund and allow retention or disposition of
such securities. The Fund will only enter into repurchase agreements
with banks and other recognized financial institutions, such as
broker/dealers, which are deemed by the Fund's adviser to be
creditworthy pursuant to guidelines established by the Trustees.

RESTRICTED AND ILLIQUID SECURITIES

The Fund may invest in commercial paper issued in reliance on the
exemption from registration afforded by Section 4(2) of the Securities
Act of 1933. Section 4(2) commercial paper is restricted as to
disposition under federal securities law, and is generally sold to
institutional investors, such as the Fund, who agree that they are
purchasing the paper for investment purposes and not with a view to
public distribution. Any resale by the purchaser must be in an exempt
transaction. Section 4(2) commercial paper is normally resold to other
institutional investors like the Fund through or with the assistance
of the issuer or investment dealers who make a market in Section 4(2)
commercial paper, thus providing liquidity. The Fund believes that
Section 4(2) commercial paper and possibly certain other restricted
securities which meet the criteria for liquidity established by the
Trustees of the Fund are quite liquid. The Fund intends, therefore, to
treat the restricted securities which meet the criteria for liquidity
established by the Trustees, including Section 4(2) commercial paper,
as determined by the Fund's investment adviser, as liquid and not
subject to the investment limitation applicable to illiquid
securities.

CREDIT ENHANCEMENT

The Fund typically evaluates the credit quality and ratings of
credit-enhanced securities based upon the financial condition and
ratings of the party providing the credit enhancement (the "credit
enhancer"), rather than the issuer. However, credit-enhanced
securities will not be treated as having been issued by the credit
enhancer for diversification purposes, unless the Fund has invested
more than 10% of its assets in securities issued, guaranteed or
otherwise credit enhanced by the credit enhancer, in which case the
securities will be treated as having been issued by both the issuer
and the credit enhancer.

The Fund may have more than 25% of its total assets invested in
securities credit enhanced by banks.

INVESTMENT LIMITATIONS

SELLING SHORT AND BUYING ON MARGIN

The Fund will not sell any securities short or purchase any securities
on margin but may obtain such short-term credits as are necessary for
clearance of transactions.

ISSUING SENIOR SECURITIES AND BORROWING MONEY

The Fund will not issue senior securities except that the Fund may
borrow money in amounts up to one-third of the value of its total
assets, including the amounts borrowed.

The Fund will not borrow money for investment leverage, but rather as
a temporary, extraordinary, or emergency measure or to facilitate
management of the portfolio by enabling the Fund to meet redemption
requests when the liquidation of portfolio securities is deemed to be
inconvenient or disadvantageous. The Fund will not purchase any
securities while borrowings in excess of 5% of the value of its total
assets are outstanding.

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 15% of the value of total assets of the
fund at the time of the pledge.

LENDING CASH OR SECURITIES

The Fund will not lend any of its assets. This shall not prevent the
Fund from purchasing or holding bonds, debentures, notes, certificates
of indebtedness or other debt securities or engaging in other
transactions where permitted by its investment objective, policies,
and limitations or the Declaration of Trust.

INVESTING IN COMMODITIES

The Fund will not purchase or sell commodities, commodity contracts,
or commodity futures contracts.

INVESTING IN REAL ESTATE

The Fund will not purchase or sell real estate, although it may invest
in securities of issuers whose business involves the purchase or sale
of real estate or in securities which are secured by real estate or
interests in real estate.

UNDERWRITING

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

CONCENTRATION OF INVESTMENTS

The Fund will not purchase securities if, as a result of such
purchase, 25% or more of the value of its total assets would be
invested in any one industry, or in industrial development bonds or
other securities, the interest upon which is paid from revenues of
similar types of projects. The Fund may invest, as temporary
investments, 25% or more of the value of its total assets in cash or
cash items, securities issued or guaranteed by the U.S. Government its
agencies or instrumentalities or instruments secured by these money
market instruments, such as repurchase agreements. The Fund does not
intend to purchase securities that would increase the percentage of
its assets invested in the securities of governmental subdivisions
located in any one state, territory, or U.S. possession to 25% or
more. However, the Fund may invest 25% or more of the value of its
assets in tax-exempt project notes guaranteed by the U.S. government,
regardless of the location of the issuing municipality. If the value
of the Fund's assets invested in securities of a governmental
subdivision changes because of changing values, the Fund will not be
required to make any reduction in its holdings.

DIVERSIFICATION OF INVESTMENTS

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, or 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) if as a result more than 5% of the value of its total
assets would be invested in the securities of that issuer, or if it
would own more than 10% of the outstanding voting securities of that
issuer.

Under this limitation, each governmental subdivision, including states
and the District of Columbia, territories, possessions of the United
States, or their political subdivisions, agencies, authorities,
instrumentalities, or similar entities, will be considered a separate
issuer if its assets and revenues are separate from those of the
governmental body creating it and the security is backed only by its
own assets and revenues. Industrial development bonds backed only by
the assets and revenues of a nongovernmental user are considered to be
issued solely by that user.

INVESTING IN RESTRICTED SECURITIES

The Fund will not invest more than 10% of its total assets in
securities subject to restrictions on resale under federal securities
law, except for restricted securities determined to be liquid under
criteria established by the Trustees.

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

INVESTING IN ILLIQUID SECURITIES

The Fund will not invest more than 10% of the value of its net assets
in illiquid securities including certain restricted securities not
determined to be liquid under criteria established by the Trustees and
non-negotiable time deposits.

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.

INVESTING FOR CONTROL

The Fund will not invest in securities of a company for the purpose of
exercising control or management.

INVESTING IN OPTIONS

The Fund will not invest in puts, calls, straddles, spreads, or any
combination of them.

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.

The Fund did not borrow money or pledge securities in excess of 5% of
the value of its net assets during the last fiscal year and has no
present intent to do so during the coming fiscal year.

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, which regulates money market mutual funds.
The Fund will determine the effective maturity of its investments, as
well as its ability to consider a security as having received the
requisite short-term ratings by NRSROs, according to Rule 2a-7. The
Fund may change these operational policies to reflect changes in the
laws and regulations without the approval of its shareholders.

TRUSTEE LIABILITY

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

INVESTMENT ADVISORY SERVICES

INVESTMENT ADVISER

The Fund's investment adviser is Federated Management. It is a subsidiary of
Federated Investors. All the voting securities of Federated Investors are
owned by a trust, the trustees of which are John F. Donahue, his wife and
his son, J. Christopher Donahue.

The adviser shall not be liable to the Trust, the Fund, or any
shareholder of the Fund 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.

ADVISORY FEES

For its advisory services, Federated Management receives an annual
investment advisory fee as described in the prospectus. For the fiscal
years ended July 31, 1997, 1996, and 1995, the adviser earned
$4,284,365, $3,668,956, and $2,318,805, respectively, of which
$2,116,877, $2,000,281, and $1,581,210, respectively, were waived.

BROKERAGE TRANSACTIONS

When selecting brokers and dealers to handle the purchase and sale of
portfolio instruments, the adviser looks for prompt execution of the
order at a favorable price. In working with dealers, the adviser will
generally use those who are recognized dealers in specific portfolio
instruments, except when a better price and execution of the order can
be obtained elsewhere. The adviser makes decisions on portfolio
transactions and selects brokers and dealers subject to guidelines
established by the Trustees. The adviser may select brokers and
dealers who offer brokerage and research services. These services may
be furnished directly to the Fund or to the adviser and may include:
advice as to the advisability of investing in securities; security
analysis and reports; economic studies; industry studies; receipt of
quotations for portfolio evaluations; and similar services. Research
services provided by brokers and dealers may be used by the adviser or
its affiliates in advising the Fund and other accounts. To the extent
that receipt of these services may supplant services for which the
adviser or its affiliates might otherwise have paid, it would tend to
reduce their expenses. The adviser and its affiliates exercise
reasonable business judgment in selecting brokers who offer brokerage
and research services to execute securities transactions. They
determine in good faith that commissions charged by such persons are
reasonable in relationship to the value of the brokerage and research
services provided. During the fiscal years ended July 31, 1997, 1996,
and 1995, the Fund paid no brokerage commissions.

Although investment decisions for the Fund are made independently from
those of the other accounts managed by the adviser, investments of the
type the Fund may make may also be made by those other accounts. When
the Fund and one or more other accounts managed by the adviser are
prepared to invest in, or desire to dispose of, the same security,
available investments or opportunities for sales will be allocated in
a manner believed by the adviser to be equitable to each. In some
cases, this procedure may adversely affect the price paid or received
by the Fund or the size of the position obtained or disposed of by the
Fund. In other cases, however, it is believed that coordination and
the ability to participate in volume transactions will be to the
benefit of the Fund.

OTHER SERVICES

FUND ADMINISTRATION

Federated Services Company, a subsidiary of Federated Investors,
provides administrative personnel and services to the Fund for a fee
as described in the prospectus. From March 1, 1994 to March 1, 1996,
Federated Administrative Services, a subsidiary of Federated
Investors, served as the Fund's Administrator. For purposes of this
Statement of Additional Information, Federated Services Company and
Federated Administrative Services may hereinafter collectively be
referred to as the "Administrators." For the fiscal years ended July
31, 1997, 1996, and 1995, the Administrators earned $1,617,952,
$1,387,430, and $877,668, respectively.

CUSTODIAN AND PORTFOLIO ACCOUNTANT

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

TRANSFER AGENT

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

INDEPENDENT PUBLIC ACCOUNTANTS

The independent public accountants for the Fund are Arthur Andersen
LLP, Pittsburgh, PA.

SHAREHOLDER SERVICES

This arrangement permits the payment of fees to Federated Shareholder
Services to cause services to be provided which are necessary for the
maintenance of shareholder accounts and to encourage personal services
to shareholders by a representative who has knowledge of the
shareholder's particular circumstances and goals. These activities and
services may include but are not limited to providing office space,
equipment, telephone facilities, and various clerical, supervisory,
computer, and other personnel as necessary or beneficial to establish
and maintain shareholder accounts and records; processing purchase and
redemption transactions and automatic investments of client account
cash balances; answering routine client inquiries; and assisting
clients in changing dividend options, account designations, and
addresses.

By adopting the Shareholder Services Agreement, the Trustees expect
that the Fund will benefit by: (1) providing personal services to
shareholders; (2) investing shareholder assets with a minimum of delay
and administrative detail; (3) enhancing shareholder recordkeeping
systems; and (4) responding promptly to shareholders' requests and
inquiries concerning their accounts.

For the fiscal year ended July 31, 1997, the Fund earned shareholder
service fees on behalf of Institutional Shares and Institutional
Service Shares in the amounts of $4,151,037 and $1,204,420,
respectively, $0 and $1,204,420 of which, respectively, was paid to
financial institutions.

DETERMINING NET ASSET VALUE

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 Rule
2a-7 (the "Rule") promulgated by the Securities and Exchange
Commission under the Investment Company Act of 1940. 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.

REDEMPTION IN KIND

The Fund is obligated to redeem shares solely in cash up to $250,000
or 1% of the Fund's net asset value, whichever is less, for any one
shareholder within a 90-day period. Any redemption beyond this amount
will also be in cash unless the Trustees determine that further
payments should be in kind. In such cases, the Fund will pay all or a
portion of the remainder of the redemption in portfolio instruments
valued in the same way as the Fund determines net asset value. The
portfolio instruments will be selected in a manner that the Trustees
deem fair and equitable. Redemption in kind is not as liquid as a cash
redemption. If redemption is made in kind, shareholders who sell these
securities could receive less than the redemption value and could
incur certain transaction costs.

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. These documents
require notice of this disclaimer to be given in each agreement,
obligation, or instrument the Trust or its Trustees enter into or
sign.

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.

THE FUND'S TAX STATUS

To qualify for the special tax treatment afforded to regulated
investment companies, the Fund must, among other requirements: derive
at least 90% of its gross income from dividends, interest, and gains
from the sale of securities; derive less than 30% of its gross income
from the sale of securities held less than three months; invest in
securities within certain statutory limits; and distribute to its
shareholders at least 90% of its net income earned during the year.

PERFORMANCE INFORMATION

Performance depends upon such variables as: portfolio quality; average
portfolio maturity; type of instruments in which the portfolio is
invested; changes in interest rates; changes in expenses; and the
relative amount of cash flow. To the extent that financial
institutions and broker/dealers charge fees in connection with
services provided in conjunction with an investment in shares of the
Fund, the performance will be reduced for those shareholders paying
those fees.

YIELD

The yield is calculated based upon the seven days ending on the day of
the calculation, called the "base period." This yield is computed 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.

For the seven-day period ended July 31, 1997, the yield for
Institutional Shares and Institutional Service Shares was 3.51%, and
3.26%, respectively.

EFFECTIVE YIELD

The effective yield is calculated by compounding the unannualized base
period return by: adding 1 to the base period return; raising the sum
to the 365/7th power; and subtracting 1 from the result.

For the seven-day period ended July 31, 1997, the effective yield for
Institutional Shares and Institutional Service Shares was 3.57%, and
3.32%, respectively.

TAX-EQUIVALENT YIELD

The tax-equivalent yield of the Fund is calculated similarly to the
yield but is adjusted to reflect the taxable yield that the Fund would
have had to earn to equal its actual yield, assuming 28% tax rate (the
maximum effective federal rate for individuals) and assuming that the
income is 100% tax exempt.

For the seven-day period ended July 31, 1997, the tax-equivalent yield
for Institutional Shares and Institutional Service Shares was 4.96%,
and 4.26%, respectively.

TAX-EQUIVALENCY TABLE

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

Note: The maximum marginal tax rate for each bracket was used in
calculating the taxable yield equivalent. Furthermore, additional
state and local taxes paid on comparable taxable investments were not
used to increase federal deductions.

The chart above is for illustrative purposes only. It is not an
indicator of past or future performance of Fund shares.

* Some portion of the Fund's income may be subject to the federal
alternative minimum tax and state and local income taxes.

TOTAL RETURN

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

The Fund's average annual total returns for the one-year and five-year
periods, and for the period from December 12, 1989, (start of
performance) to July 31, 1997, were 3.49%, 3.13%, and 3.70%,
respectively for Institutional Shares.

The Fund's average annual total returns for the one-year period and
for the period from July 5, 1994, (date of initial public offering) to
July 31, 1997, were 3.24% and 3.28%, respectively, for Institutional
Service Shares.

PERFORMANCE COMPARISONS

Investors may use financial publications and/or indices to obtain a
more complete view of the Fund's performance. When comparing
performance, investors should consider all relevant factors such as
the composition of any index used, prevailing market conditions,
portfolio compositions of other funds, and methods used to value
portfolio securities and compute offering price. The financial
publications and/or indices which the Fund uses in advertising may
include:

   * Lipper 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.

   * IBC/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.

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

   * Salomon 30-Day CD Index compares rate levels of 30-day
     certificates of deposit from the top ten prime representative
     banks.

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

ECONOMIC AND MARKET INFORMATION

Advertising and sales literature for the Fund may include discussions

rating (long-term rating) addresses the likelihood of repayment of
principal and interest when due, and the second rating (short-term
rating) describes the demand characteristics. Several examples are
AAA/A-l+, AA/A-I+, A/A-1. (The definitions for the long-term and the
short-term ratings are provided below.)

COMMERCIAL PAPER (CP) RATINGS

An S&P commercial paper rating is a current assessment of the
likelihood of timely payment of debt having an original maturity of no
more than 365 days.

A-1-- This highest category indicates that the degree of safety
regarding timely payment is strong. Those issues determined to possess
extremely strong safety characteristics are denoted with a plus sign
(+) designation.

A-2-- Capacity for timely payment on issues with this designation is
satisfactory. However, the relative degree of safety is not as high as
for issues designated A-1.

LONG-TERM DEBT RATINGS

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

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

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

MOODY'S INVESTORS SERVICE, INC., SHORT-TERM MUNICIPAL OBLIGATIONS RATINGS

Moody's Investor Service, Inc. (Moody's) short-term ratings are
designated Moody's Investment Grade (MIG or VMIG) (see below). The
purpose of the MIG or VMIG ratings is to provide investors with a
simple system by which the relative investment qualities of short-term
obligations may be evaluated.

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

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

VARIABLE RATE DEMAND NOTES (VRDNS) AND TENDER OPTION BONDS (TOBS) RATINGS

Short-term ratings on issues with demand features are differentiated
by the use of the VMIG symbol to reflect such characteristics as
payment upon periodic demand rather than fixed maturity dates and
payment relying on external liquidity. In this case, two ratings are
usually assigned, (for example, Aaa/VMIG-1); the first representing an
evaluation of the degree of risk associated with scheduled principal
and interest payments, and the second representing an evaluation of
the degree of risk associated with the demand feature. The VMIG rating
can be assigned a 1 or 2 designation using the same definitions
described above for the MIG rating.

COMMERCIAL PAPER (CP) RATINGS

P-1-- Issuers rated Prime-1 (or related supporting institutions) have
a superior capacity for repayment of short-term promissory
obligations. Prime-1 repayment capacity will normally be evidenced by
the following characteristics: leading market positions in well
established industries, high rates of return on funds employed,
conservative capitalization structure with moderate reliance on debt
and ample asset protection, broad margins in earning coverage of fixed
financial charges and high internal cash generation, well-established
access to a range of financial markets and assured sources of
alternate liquidity.

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

LONG-TERM DEBT RATINGS

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

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

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

NR-- Indicates that both the bonds and the obligor or credit enhancer
are not currently rated by S&P or Moody's with respect to short-term
indebtedness. However, management considers them to be of comparable
quality to securities rated A-1 or P-1.

NR(1)-- The underlying issuer/obligor/guarantor has other outstanding
debt rated "AAA" by S&P or "Aaa" by Moody's.

NR(2)-- The underlying issuer/obligor/guarantor has other outstanding
debt rated "AA" by S&P or "Aa" by Moody's.

NR(3)-- The underlying issuer/obligor/guarantor has other outstanding
debt rated "A" by S&P or Moody's.

FITCH INVESTORS SERVICE, INC. SHORT-TERM DEBT RATING DEFINITIONS

F-1+-- Exceptionally Strong Credit Quality. Issues assigned this
rating are regarded as having the strongest degree of assurance for
timely payment.

F-1-- Very Strong Credit Quality. Issues assigned this rating reflect
an assurance for timely payment, only slightly less in degree than
issues rated F-1+.

F-2-- Good Credit Quality. Issues carrying this rating have a
satisfactory degree of assurance for timely payment, but the margin of
safety is not as great as for issues assigned F-1+ and F-1 ratings.

                            GENERAL INFORMATION

The Trust was established as a Massachusetts business trust under a
Declaration of Trust dated October 3, 1988. The Declaration of Trust
permits the Trust to offer separate series of shares representing
interests in separate portfolios of securities. The shares in any one
portfolio may be offered in separate classes. With respect to this
Fund, as of the date of this prospectus, the Board of Trustees (the
"Trustees") has established three classes of shares known as
Institutional Shares, Institutional Service Shares, and Institutional
Capital Shares. This prospectus relates only to Institutional Shares
of the Fund, which are designed primarily for entities holding shares
in an agency or fiduciary capacity, financial institutions, financial
intermediaries and institutional investors as a convenient means of
accumulating an interest in a professionally managed portfolio
investing in short-term U.S. Treasury securities. A minimum initial
investment of $1,000,000 over a one-year period is required.

The Fund attempts to stabilize the value of a share at $1.00. Shares
are currently sold and redeemed at that price.

                           INVESTMENT INFORMATION

INVESTMENT OBJECTIVE

The investment objective of the Fund is current income consistent with
stability of principal. This investment objective cannot be changed
without shareholder approval. While there is no assurance that the
Fund will achieve its investment objective, it endeavors to do so by
complying with the diversification and other requirements of Rule 2a-7
under the Investment Company Act of 1940 which regulates money market
mutual funds and by following the investment policies described in
this prospectus.

INVESTMENT POLICIES

The Fund pursues its investment objective by investing only in a
portfolio of U.S. Treasury securities maturing in 13 months or less.
The average maturity of the securities in the Fund's portfolio,
computed on a dollar-weighted basis, will be 90 days or less. Unless
indicated otherwise, the investment policies may be changed by the
Trustees without shareholder approval. Shareholders will be notified
before any material change in these policies becomes effective.

ACCEPTABLE INVESTMENTS

The Fund invests only in U.S. Treasury securities, which are fully
guaranteed as to principal and interest by the United States.

REPURCHASE AGREEMENTS

Certain securities in which the Fund invests may be purchased pursuant
to repurchase agreements. Repurchase agreements are arrangements in
which banks, broker/dealers, and other recognized financial
institutions sell securities to the Fund and agree at the time of sale
to repurchase them at a mutually agreed upon time and price. To the
extent that the seller does not repurchase the securities from the
Fund, the Fund could receive less than the repurchase price on any
sale of such securities.

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

The Fund may purchase securities on a when-issued or delayed delivery
basis. These transactions are arrangements in which the Fund purchases
securities with payment and delivery scheduled for a future time. The
seller's failure to complete these transactions may cause the Fund to
miss a price or yield considered to be advantageous. Settlement dates
may be a month or more after entering into these transactions, and the
market values of the securities purchased may vary from the purchase
prices.

The Fund may dispose of a commitment prior to settlement if the
adviser deems it appropriate to do so. In addition, the Fund may enter
into transactions to sell its purchase commitments to third parties at
current market values and simultaneously acquire other commitments to
purchase similar securities at later dates. The Fund may realize
short-term profits or losses upon the sale of such commitments.

LENDING OF PORTFOLIO SECURITIES

In order to generate additional income, the Fund may lend its
portfolio securities on a short-term or long-term basis, or both, to
broker/dealers, banks, or other institutional borrowers of securities.
The Fund will only enter into loan arrangements with broker/dealers,
banks, or other institutions which the adviser has determined are
creditworthy under guidelines established by the Fund's Trustees and
will receive collateral at all times equal to at least 100% of the
value of the securities loaned. There is the risk that when lending
portfolio securities, the securities may not be available to the Fund
on a timely basis and the Fund may, therefore, lose the opportunity to
sell the securities at a desirable price. In addition, in the event
that a borrower of securities would file for bankruptcy or become
insolvent, disposition of the securities may be delayed pending court
action.

INVESTMENT LIMITATIONS

The Fund will not borrow money or pledge securities except, under
certain circumstances, the Fund may borrow up to one-third of the
value of its total assets and pledge up to 15% of the value of those
assets to secure such borrowings.

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

The Fund will not invest more than 10% of its net assets in illiquid
securities, including repurchase agreements providing for settlement
in more than seven days after notice.

                              FUND INFORMATION

MANAGEMENT OF THE FUND

BOARD OF TRUSTEES

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

INVESTMENT ADVISER

Investment decisions for the Fund are made by Federated Management,
the Fund's investment adviser, subject to direction by the Trustees.
The adviser continually conducts investment research and supervision
for the Fund and is responsible for the purchase and sale of portfolio
instruments.

ADVISORY FEES

The adviser receives an annual investment advisory fee equal to 0.20%
of the Fund's average daily net assets. The adviser may voluntarily
choose to waive a portion of its fee or reimburse other expenses of
the Fund, but reserves the right to terminate such waiver or
reimbursement at any time at its sole discretion.

ADVISER'S BACKGROUND

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

Federated Management and other subsidiaries of Federated Investors
serve as investment advisers to a number of investment companies and
private accounts. Certain other subsidiaries also provide
administrative services to a number of investment companies. With over
$110 billion invested across over 300 funds under management and/or
administration by its subsidiaries, as of December 31, 1996, Federated
Investors is one of the largest mutual fund investment managers in the
United States. With more than 2,000 employees, Federated continues to
be led by the management who founded the company in 1955. Federated
funds are presently at work in and through 4,500 financial
institutions nationwide.

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

DISTRIBUTION OF INSTITUTIONAL SHARES

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

Investors.

SHAREHOLDER SERVICES

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

SUPPLEMENTAL PAYMENTS TO FINANCIAL INSTITUTIONS

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

ADMINISTRATION OF THE FUND

ADMINISTRATIVE SERVICES

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

 MAXIMUM            AVERAGE AGGREGATE
   FEE              DAILY NET ASSETS

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

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

                              NET ASSET VALUE

The Fund attempts to stabilize the net asset value of shares at $1.00
by valuing the portfolio securities using the amortized cost method.
The net asset value per share is determined by subtracting liabilities
attributable to Institutional Shares from the value of Fund assets
attributable to Institutional Shares, and dividing the remainder by
the number of Institutional Shares outstanding. The Fund cannot
guarantee that its net asset value will always remain at $1.00 per
share.

The net asset value is determined at 5:00 p.m. (Eastern time), Monday
through Friday, except on New Year's Day, Martin Luther King Day,
Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor
Day, Thanksgiving Day, and Christmas Day.

                           HOW TO PURCHASE SHARES

Shares are sold at their net asset value, without a sales charge, next
determined after an order is received, on days on which the New York
Stock Exchange is open for business. Shares may be purchased either by
wire or by check. The Fund reserves the right to reject any purchase
request.

To make a purchase, open an account by calling Federated Securities
Corp. Information needed to establish the account will be taken by
telephone. The minimum initial investment is $1,000,000. However, an
account may be opened with a smaller amount as long as the minimum is
reached within one year of opening the account. Financial institutions
may impose different minimum investment requirements on their
customers.

PURCHASING SHARES BY WIRE

Shares may be purchased by Federal Reserve wire by calling the Fund
before 5:00 p.m. (Eastern time) to place an order. The order is
considered received immediately. Payment by federal funds must be
received before 5:00 p.m. (Eastern time) that day. Federal funds
should be wired as follows: Federated Shareholder Services Company,
c/o State Street Bank and Trust Company, Boston, MA; Attention:
EDGEWIRE; For Credit to: Treasury Obligations Fund--Institutional
Shares; Fund Number (this number can be found on the account statement
or by contacting the Fund); Group Number or Order Number; Nominee or
Institution Name; and ABA Number 011000028. Shares cannot be purchased
by wire on holidays when wire transfers are restricted. Questions on
wire purchases should be directed to your shareholder services
representative at the telephone number listed on your account
statement.

PURCHASING SHARES BY CHECK

Shares may be purchased by sending a check to Federated Shareholder
Services Company, P.O. Box 8600, Boston, MA 02266-8600. The check
should be made payable to: Treasury Obligations Fund--Institutional
Shares. 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.

INVEST-BY-PHONE

Once an account has been opened, a shareholder may use invest-by-phone
for investments if an authorization form has been filed with Federated
Shareholder Services Company, the transfer agent for shares of the
Fund. Approximately two weeks after sending the form to Federated
Shareholder Services Company, the shareholder may call Federated
Shareholder Services Company to purchase shares. Federated Shareholder
Services Company will send a request for monies to the shareholder's
commercial bank, savings bank, or credit union ("bank") via the
Automated Clearing House. The shareholder's bank, which must be an
Automated Clearing House member, will then forward the monies to
Federated Shareholder Services Company. The purchase is normally
entered the next business day after the initial phone request. For
further information and an application, call the Fund.

                            HOW TO REDEEM SHARES

Shares are redeemed at their net asset value next determined after
Federated Shareholder Services Company receives the redemption
request. Redemptions will be made on days on which the Fund computes
its net asset value. Redemption requests must be received in proper
form and can be made as described below.

REDEEMING SHARES BY TELEPHONE

Redemptions in any amount may be made by calling the Fund provided the
Fund has a properly completed authorization form. These forms can be
obtained from Federated Securities Corp. Proceeds from redemption
requests received before 5:00 p.m. (Eastern time) will be wired the
same day to the shareholder's account at a domestic commercial bank
which is a member of the Federal Reserve System, but will not include
that day's dividend. Proceeds from redemption requests on holidays
when wire transfers are restricted will be wired the following
business day. Questions about telephone redemptions on days when wire
transfers are restricted should be directed to your shareholder
services representative at the telephone number listed on your account
statement.

Telephone instructions may be recorded and if reasonable procedures
are not followed by the Fund, it may be liable for losses due to
unauthorized or fraudulent telephone instructions.

In the event of drastic economic or market changes, a shareholder may
experience difficulty in redeeming by telephone. If this occurs,
"Redeeming Shares by Mail" should be considered. If at any time the
Fund shall determine it necessary to terminate or modify the telephone
redemption privilege, shareholders would be promptly notified.

REDEEMING SHARES BY MAIL

Shares may be redeemed in any amount by mailing a written request to:
Federated Shareholder Services Company, P.O. Box 8600, Boston, MA
02266-8600. If share certificates have been issued, they should be
sent unendorsed with the written request by registered or certified
mail to the address noted above.

The written request should state: the Fund name and the class
designation; the account name as registered with the Fund; the account
number; and the number of shares to be redeemed or the dollar amount
requested. All owners of the account must sign the request exactly as
the shares are registered. Normally, a check for the proceeds is
mailed within one business day, but in no event more than seven days,
after the receipt of a proper written redemption request. Dividends
are paid up to and including the day that a redemption request is
processed.

Shareholders requesting a redemption of any amount to be sent to an
address other than that on record with the Fund or a redemption
payable other than to the shareholder of record must have their
signatures guaranteed by a commercial or savings bank, trust company
or savings association whose deposits are insured by an organization
which is administered by the Federal Deposit Insurance Corporation; a
member firm of a domestic stock exchange; or any other "eligible
guarantor institution," as defined in the Securities Exchange Act of
1934. The Fund does not accept signatures guaranteed by a notary
public.

                       ACCOUNT AND SHARE INFORMATION

DIVIDENDS

Dividends are declared daily and paid monthly. Dividends are
automatically reinvested on payment dates in additional shares of the
Fund unless cash payments are requested by writing to the Fund. Shares
purchased by wire before 5:00 p.m. (Eastern time) begin earning
dividends that day. Shares purchased by check begin earning dividends
the day after the check is converted into federal funds.

CAPITAL GAINS

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 will distribute in cash or
additional shares any realized net long-term capital gains at least
once every 12 months.

CONFIRMATIONS AND ACCOUNT STATEMENTS

Shareholders will receive detailed confirmations of transactions
(except for systematic program transactions). In addition,
shareholders will receive periodic statements reporting all account
activity, including dividends paid. The Fund will not issue share
certificates.

ACCOUNTS WITH LOW BALANCES

Due to the high cost of maintaining accounts with low balances, the
Fund may redeem shares in any account, except accounts maintained by
retirement plans, and pay the proceeds to the shareholder if the
account balance falls below a required minimum value of $1,000,000 due
to shareholder redemptions. Before shares are redeemed to close an
account, the shareholder is notified in writing and allowed 30 days to
purchase additional shares to meet the minimum requirement.

VOTING RIGHTS

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

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

                              TAX INFORMATION

FEDERAL INCOME TAX

The Fund will pay no federal income tax because it expects to meet
requirements of the Internal Revenue Code applicable to regulated
investment companies and to receive the special tax treatment afforded
to such companies. The Fund will be treated as a single, separate
entity for federal income tax purposes so that income (including
capital gains) and losses realized by the Trust's other portfolios
will not be combined for tax purposes with those realized by the Fund.

Unless otherwise exempt, shareholders are required to pay federal
income tax on any dividends and other distributions received. This
applies whether dividends and distributions are received in cash or as
additional shares.

STATE AND LOCAL TAXES

In the opinion of Houston, Donnelly & Meck, counsel to the Trust, Fund
shares may be subject to personal property taxes imposed by counties,
municipalities, and school districts in Pennsylvania to the extent
that the portfolio securities in the Fund would be subject to such
taxes if owned directly by residents of those jurisdictions.

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

                          OTHER CLASSES OF SHARES

The Fund also offers other classes. Institutional Service Shares and
Institutional Capital Shares are sold at net asset value primarily to
financial institutions, financial intermediaries and institutional
investors and are subject to a minimum initial investment of
$1,000,000.

All classes are subject to certain of the same expenses.

Institutional Service Shares are distributed with no 12b-1 Plan but
are subject to shareholder services fees.

Institutional Capital Shares are distributed with no 12b-1 Plan but
are subject to shareholder services fees.

Expense differences between classes may affect the performance of each
class.

To obtain more information and a prospectus for any other class,
investors may call 1-800-341-7400.

                          PERFORMANCE INFORMATION

From time to time, the Fund advertises its yield, effective yield and
total return. The performance figures will be calculated separately
for each class of shares.

Yield represents the annualized rate of income earned on an investment
over a seven-day period. It is the annualized dividends earned during
the period on an investment shown as a percentage of the investment.
The effective yield is calculated similarly to the yield, but when
annualized, the income earned by an investment is assumed to be
reinvested daily. The effective yield will be slightly higher than the
yield because of the compounding effect of this assumed reinvestment.

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

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

                       NOTES TO FINANCIAL STATEMENTS

                          TREASURY OBLIGATIONS FUND

                               JULY 31, 1997

ORGANIZATION

Money Market Obligations Trust (the "Trust") is registered under the
Investment Company Act of 1940, as amended (the "Act") as an open-end,
management investment company. The Trust consists of six portfolios.
The financial statements included herein are only those of Treasury
Obligations Fund (the "Fund"), a diversified portfolio. The financial
statements of the other portfolios are presented separately. The
assets of each portfolio are segregated and a shareholder's interest
is limited to the portfolio in which shares are held. The investment
objective of the Fund is current income consistent with stability of
principal.

The Fund offers three classes of shares: Institutional Shares, Institutional
Service Shares, and Institutional Capital Shares. Effective April 14, 1997,
the Trust added Institutional Capital Shares.

SIGNIFICANT ACCOUNTING POLICIES

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

INVESTMENT VALUATIONS

The Fund uses the amortized cost method to value its portfolio
securities in accordance with Rule 2a-7 under the Act.

REPURCHASE AGREEMENTS

It is the policy of the Fund to require the custodian bank to take
possession, to have legally segregated in the Federal Reserve Book
Entry System, or to have segregated within the custodian bank's vault,
all securities held as collateral under repurchase agreement
transactions. Additionally, procedures have been established by the
Fund to monitor, on a daily basis, the market value of each repurchase
agreement's collateral to ensure that the value of collateral at least
equals the repurchase price to be paid under the repurchase agreement
transaction.

The Fund will only enter into repurchase agreements with banks and
other recognized financial institutions, such as broker/dealers, which
are deemed by the Fund's adviser to be creditworthy pursuant to the
guidelines and/or standards reviewed or established by the Board of
Trustees (the "Trustees"). Risks may arise from the potential
inability of counterparties to honor the terms of the repurchase
agreement. Accordingly, the Fund could receive less than the
repurchase price on the sale of collateral securities.

INVESTMENT INCOME, EXPENSES AND DISTRIBUTIONS

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

FEDERAL TAXES

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

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

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

USE OF ESTIMATES

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

OTHER

Investment transactions are accounted for on the trade date.

SHARES OF BENEFICIAL INTEREST

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

Transactions in shares were as follows:

                  REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Shareholders and Board of Trustees of
MONEY MARKET OBLIGATIONS TRUST

(Treasury Obligations Fund):

We have audited the accompanying statement of assets and liabilities
of Treasury Obligations Fund (an investment portfolio of Money Market
Obligations Trust, a Massachusetts business trust), including the
schedule of portfolio investments, as of July 31, 1997, the related
statement of operations for the year then ended, the statement of
changes in net assets for each of the two years in the period then
ended, and the financial highlights for the periods presented. These
financial statements and financial highlights are the responsibility
of the Trust's management. Our responsibility is to express an opinion
on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements
and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts
and disclosures in the financial statements. Our procedures included
confirmation of securities owned as of July 31, 1997, by
correspondence with the custodian. An audit also includes assessing
the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements and financial highlights
referred to above present fairly, in all material respects, the
financial position of Treasury Obligations Fund (an investment
portfolio of Money Market Obligations Trust) as of July 31, 1997, the
results of its operations for the year then ended, the changes in its
net assets for each of the two years in the period then ended, and its
financial highlights for the periods presented, in conformity with
generally accepted accounting principles.

                            GENERAL INFORMATION

The Trust was established as a Massachusetts business trust under a
Declaration of Trust dated October 3, 1988. The Declaration of Trust
permits the Trust to offer separate series of shares representing
interests in separate portfolios of securities. The shares in any one
portfolio may be offered in separate classes. With respect to this
Fund, as of the date of this prospectus, the Board of Trustees (the
"Trustees") has established three classes of shares known as
Institutional Shares, Institutional Service Shares, and Institutional
Capital Shares. This prospectus relates only to Institutional Service
Shares of the Fund, which are designed primarily for financial
institutions, financial intermediaries and institutional investors as
a convenient means of accumulating an interest in a professionally
managed portfolio investing in short-term U.S. Treasury securities. A
minimum initial investment of $1,000,000 over a one-year period is
required.

The Fund attempts to stabilize the value of a share at $1.00. Shares
are currently sold and redeemed at that price.

                           INVESTMENT INFORMATION

INVESTMENT OBJECTIVE

The investment objective of the Fund is current income consistent with
stability of principal. This investment objective cannot be changed
without shareholder approval. While there is no assurance that the
Fund will achieve its investment objective, it endeavors to do so by
complying with the diversification and other requirements of Rule 2a-7
under the Investment Company Act of 1940 which regulates money market
mutual funds and by following the investment policies described in
this prospectus.

INVESTMENT POLICIES

The Fund pursues its investment objective by investing only in a
portfolio of U.S. Treasury securities maturing in 13 months or less.
The average maturity of the securities in the Fund's portfolio,
computed on a dollar-weighted basis, will be 90 days or less. Unless
indicated otherwise, the investment policies may be changed by the
Trustees without shareholder approval. Shareholders will be notified
before any material change in these policies becomes effective.

ACCEPTABLE INVESTMENTS

The Fund invests only in U.S. Treasury securities, which are fully
guaranteed as to principal and interest by the United States.

REPURCHASE AGREEMENTS

Certain securities in which the Fund invests may be purchased pursuant
to repurchase agreements. Repurchase agreements are arrangements in
which banks, broker/dealers, and other recognized financial
institutions sell securities to the Fund and agree at the time of sale
to repurchase them at a mutually agreed upon time and price. To the
extent that the seller does not repurchase the securities from the
Fund, the Fund could receive less than the repurchase price on any
sale of such securities.

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

The Fund may purchase securities on a when-issued or delayed delivery
basis. These transactions are arrangements in which the Fund purchases
securities with payment and delivery scheduled for a future time. The
seller's failure to complete these transactions may cause the Fund to
miss a price or yield considered to be advantageous. Settlement dates
may be a month or more after entering into these transactions, and the
market values of the securities purchased may vary from the purchase
prices.

The Fund may dispose of a commitment prior to settlement if the
adviser deems it appropriate to do so. In addition, the Fund may enter
into transactions to sell its purchase commitments to third parties at
current market values and simultaneously acquire other commitments to
purchase similar securities at later dates. The Fund may realize
short-term profits or losses upon the sale of such commitments.

LENDING OF PORTFOLIO SECURITIES

In order to generate additional income, the Fund may lend its
portfolio securities on a short-term or long-term basis, or both, to
broker/dealers, banks, or other institutional borrowers of securities.
The Fund will only enter into loan arrangements with broker/dealers,
banks, or other institutions which the adviser has determined are
creditworthy under guidelines established by the Fund's Trustees and
will receive collateral at all times equal to at least 100% of the
value of the securities loaned. There is the risk that when lending
portfolio securities, the securities may not be available to the Fund
on a timely basis and the Fund may, therefore, lose the opportunity to
sell the securities at a desirable price. In addition, in the event
that a borrower of securities would file for bankruptcy or become
insolvent, disposition of the securities may be delayed pending court
action.

INVESTMENT LIMITATIONS

The Fund will not borrow money or pledge securities except, under
certain circumstances, the Fund may borrow up to one-third of the
value of its total assets and pledge up to 15% of the value of those
assets to secure such borrowings.

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

The Fund will not invest more than 10% of its net assets in illiquid
securities, including repurchase agreements providing for settlement
in more than seven days after notice.

                              FUND INFORMATION

MANAGEMENT OF THE FUND

BOARD OF TRUSTEES

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

INVESTMENT ADVISER

Investment decisions for the Fund are made by Federated Management,
the Fund's investment adviser, subject to direction by the Trustees.
The adviser continually conducts investment research and supervision
for the Fund and is responsible for the purchase and sale of portfolio
instruments.

ADVISORY FEES

The adviser receives an annual investment advisory fee equal to 0.20%
of the Fund's average daily net assets. The adviser may voluntarily
choose to waive a portion of its fee or reimburse other expenses of
the Fund, but reserves the right to terminate such waiver or
reimbursement at any time at its sole discretion.

ADVISER'S BACKGROUND

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

Federated Management and other subsidiaries of Federated Investors
serve as investment advisers to a number of investment companies and
private accounts. Certain other subsidiaries also provide
administrative services to a number of investment companies. With
over$110 billion invested across over 300 funds under management
and/or administration by its subsidiaries, as of December 31, 1996,
Federated Investors is one of the largest mutual fund investment
managers in the United States. With more than 2,000 employees,
Federated continues to be led by the management who founded the
company in 1955. Federated funds are presently at work in and through
4,500 financial institutions nationwide.

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

DISTRIBUTION OF INSTITUTIONAL SERVICE SHARES

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

Federated Investors.

SHAREHOLDER SERVICES

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

SUPPLEMENTAL PAYMENTS TO FINANCIAL INSTITUTIONS

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

ADMINISTRATION OF THE FUND

ADMINISTRATIVE SERVICES

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

MAXIMUM                AVERAGE AGGREGATE
  FEE                  DAILY NET ASSETS

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

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

                              NET ASSET VALUE

The Fund attempts to stabilize the net asset value of shares at $1.00
by valuing the portfolio securities using the amortized cost method.
The net asset value per share is determined by subtracting liabilities
attributable to Institutional Service Shares from the value of Fund
assets attributable to Institutional Service Shares, and dividing the
remainder by the number of Institutional Service Shares outstanding.
The Fund cannot guarantee that its net asset value will always remain
at $1.00 per share.

The net asset value is determined at 5:00 p.m. (Eastern time), Monday
through Friday, except on New Year's Day, Martin Luther King Day,
Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor
Day, Thanksgiving Day, and Christmas Day.

                           HOW TO PURCHASE SHARES

Shares are sold at their net asset value, without a sales charge, next
determined after an order is received, on days on which the New York
Stock Exchange is open for business. Shares may be purchased either by
wire or by check. The Fund reserves the right to reject any purchase
request.

To make a purchase, open an account by calling Federated Securities
Corp. Information needed to establish the account will be taken by
telephone. The minimum initial investment is $1,000,000. However, an
account may be opened with a smaller amount as long as the minimum is
reached within one year of opening the account. Financial institutions
may impose different minimum investment requirements on their
customers.

PURCHASING SHARES BY WIRE

Shares may be purchased by Federal Reserve wire by calling the Fund
before 5:00 p.m. (Eastern time) to place an order. The order is
considered received immediately. Payment by federal funds must be
received before 5:00 p.m. (Eastern time) that day. Federal funds
should be wired as follows: Federated Shareholder Services Company,
c/o State Street Bank and Trust Company, Boston, MA; Attention:
EDGEWIRE; For Credit to: Treasury Obligations Fund -- Institutional
Service Shares; Fund Number (this number can be found on the account
statement or by contacting the Fund); Group Number or Order Number;
Nominee or Institution Name; and ABA Number 011000028. Shares cannot
be purchased by wire on holidays when wire transfers are restricted.
Questions on wire purchases should be directed to your shareholder
services representative at the telephone number listed on your account
statement.

PURCHASING SHARES BY CHECK

Shares may be purchased by sending a check to Federated Shareholder
Services Company, P.O. Box 8600, Boston, MA 02266-8600. The check
should be made payable to: Treasury Obligations Fund--Institutional
Service Shares. 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.

INVEST-BY-PHONE

Once an account has been opened, a shareholder may use invest-by-phone
for investments if an authorization form has been filed with Federated
Shareholder Services Company, the transfer agent for shares of the
Fund. Approximately two weeks after sending the form to Federated
Shareholder Services Company, the shareholder may call Federated
Shareholder Services Company to purchase shares. Federated Shareholder
Services Company will send a request for monies to the shareholder's
commercial bank, savings bank, or credit union ("bank") via the
Automated Clearing House. The shareholder's bank, which must be an
Automated Clearing House member, will then forward the monies to
Federated Shareholder Services Company. The purchase is normally
entered the next business day after the initial phone request. For
further information and an application, call the Fund.

                            HOW TO REDEEM SHARES

Shares are redeemed at their net asset value next determined after
Federated Shareholder Services Company receives the redemption
request. Redemptions will be made on days on which the Fund computes
its net asset value. Redemption requests must be received in proper
form and can be made as described below.

REDEEMING SHARES BY TELEPHONE

Redemptions in any amount may be made by calling the Fund provided the
Fund has a properly completed authorization form. These forms can be
obtained from Federated Securities Corp. Proceeds from redemption
requests received before 5:00 p.m. (Eastern time) will be wired the
same day to the shareholder's account at a domestic commercial bank
which is a member of the Federal Reserve System, but will not include
that day's dividend. Proceeds from redemption requests on holidays
when wire transfers are restricted will be wired the following
business day. Questions about telephone redemptions on days when wire
transfers are restricted should be directed to your shareholder
services representative at the telephone number listed on your account
statement.

Telephone instructions may be recorded and if reasonable procedures
are not followed by the Fund, it may be liable for losses due to
unauthorized or fraudulent telephone instructions.

In the event of drastic economic or market changes, a shareholder may
experience difficulty in redeeming by telephone. If this occurs,
"Redeeming Shares by Mail" should be considered. If at any time the
Fund shall determine it necessary to terminate or modify the telephone
redemption privilege, shareholders would be promptly notified.

REDEEMING SHARES BY MAIL

Shares may be redeemed in any amount by mailing a written request to:
Federated Shareholder Services Company, P.O. Box 8600, Boston, MA
02266-8600. If share certificates have been issued, they should be
sent unendorsed with the written request by registered or certified
mail to the address noted above.

The written request should state: the Fund name and the class
designation; the account name as registered with the Fund; the account
number; and the number of shares to be redeemed or the dollar amount
requested. All owners of the account must sign the request exactly as
the shares are registered. Normally, a check for the proceeds is
mailed within one business day, but in no event more than seven days,
after the receipt of a proper written redemption request. Dividends
are paid up to and including the day that a redemption request is
processed.

Shareholders requesting a redemption of any amount to be sent to an
address other than that on record with the Fund or a redemption
payable other than to the shareholder of record must have their
signatures guaranteed by a commercial or savings bank, trust company
or savings association whose deposits are insured by an organization
which is administered by the Federal Deposit Insurance Corporation; a
member firm of a domestic stock exchange; or any other "eligible
guarantor institution," as defined in the Securities Exchange Act of
1934. The Fund does not accept signatures guaranteed by a notary
public.

                       ACCOUNT AND SHARE INFORMATION

DIVIDENDS

Dividends are declared daily and paid monthly. Dividends are
automatically reinvested on payment dates in additional shares of the
Fund unless cash payments are requested by writing to the Fund. Shares
purchased by wire before 5:00 p.m. (Eastern time) begin earning
dividends that day. Shares purchased by check begin earning dividends
the day after the check is converted into federal funds.

CAPITAL GAINS

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 will distribute in cash or
additional shares any realized net long-term capital gains at least
once every 12 months.

CONFIRMATIONS AND ACCOUNT STATEMENTS

Shareholders will receive detailed confirmations of transactions
(except for systematic program transactions). In addition,
shareholders will receive periodic statements reporting all account
activity, including dividends paid. The Fund will not issue share
certificates.

ACCOUNTS WITH LOW BALANCES

Due to the high cost of maintaining accounts with low balances, the
Fund may redeem shares in any account, except accounts maintained by
retirement plans, and pay the proceeds to the shareholder if the
account balance falls below a required minimum value of $1,000,000 due
to shareholder redemptions. Before shares are redeemed to close an
account, the shareholder is notified in writing and allowed 30 days to
purchase additional shares to meet the minimum requirement.

VOTING RIGHTS

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

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

                              TAX INFORMATION

FEDERAL INCOME TAX

The Fund will pay no federal income tax because it expects to meet
requirements of the Internal Revenue Code applicable to regulated
investment companies and to receive the special tax treatment afforded
to such companies. The Fund will be treated as a single, separate
entity for federal income tax purposes so that income (including
capital gains) and losses realized by the Trust's other portfolios
will not be combined for tax purposes with those realized by the Fund.

Unless otherwise exempt, shareholders are required to pay federal
income tax on any dividends and other distributions received. This
applies whether dividends and distributions are received in cash or as
additional shares.

STATE AND LOCAL TAXES

In the opinion of Houston, Donnelly & Meck, counsel to the Trust, Fund
shares may be subject to personal property taxes imposed by counties,
municipalities, and school districts in Pennsylvania to the extent
that the portfolio securities in the Fund would be subject to such
taxes if owned directly by residents of those jurisdictions.

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

                          OTHER CLASSES OF SHARES

The Fund also offers other classes. Institutional Shares are sold at
net asset value primarily to entities holding shares in an agency or
fiduciary capacity, financial institutions, financial intermediaries
and institutional investors and are subject to a minimum initial
investment of $1,000,000. Institutional Capital Shares are sold at net
asset value primarily to financial institutions, financial
intermediaries and institutional investors and are subject to a
minimum initial investment of $1,000,000.

All classes are subject to certain of the same expenses.

Institutional Shares are distributed with no 12b-1 Plan but are
subject to shareholder services fees.

Institutional Capital Shares are distributed with no 12b-1 Plan but
are subject to shareholder services fees.

Expense differences between classes may affect the performance of each
class.

To obtain more information and a prospectus for any other class,
investors may call 1-800-341-7400.

                          PERFORMANCE INFORMATION

From time to time, the Fund advertises its yield, effective yield and
total return. The performance figures will be calculated separately
for each class of shares.

Yield represents the annualized rate of income earned on an investment
over a seven-day period. It is the annualized dividends earned during
the period on an investment shown as a percentage of the investment.
The effective yield is calculated similarly to the yield, but when
annualized, the income earned by an investment is assumed to be
reinvested daily. The effective yield will be slightly higher than the
yield because of the compounding effect of this assumed reinvestment.

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

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

                       NOTES TO FINANCIAL STATEMENTS

                          TREASURY OBLIGATIONS FUND

                               JULY 31, 1997

ORGANIZATION

Money Market Obligations Trust (the "Trust") is registered under the
Investment Company Act of 1940, as amended (the "Act") as an open-end,
management investment company. The Trust consists of six portfolios.
The financial statements included herein are only those of Treasury
Obligations Fund (the "Fund"), a diversified portfolio. The financial
statements of the other portfolios are presented separately. The
assets of each portfolio are segregated and a shareholder's interest
is limited to the portfolio in which shares are held. The investment
objective of the Fund is current income consistent with stability of
principal.

The Fund offers three classes of shares: Institutional Shares, Institutional
Service Shares, and Institutional Capital Shares. Effective April 14, 1997,
the Trust added Institutional Capital Shares.

SIGNIFICANT ACCOUNTING POLICIES

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

INVESTMENT VALUATIONS

The Fund uses the amortized cost method to value its portfolio
securities in accordance with Rule 2a-7 under the Act.

REPURCHASE AGREEMENTS

It is the policy of the Fund to require the custodian bank to take
possession, to have legally segregated in the Federal Reserve Book
Entry System, or to have segregated within the custodian bank's vault,
all securities held as collateral under repurchase agreement
transactions. Additionally, procedures have been established by the
Fund to monitor, on a daily basis, the market value of each repurchase
agreement's collateral to ensure that the value of collateral at least
equals the repurchase price to be paid under the repurchase agreement
transaction.

The Fund will only enter into repurchase agreements with banks and
other recognized financial institutions, such as broker/dealers, which
are deemed by the Fund's adviser to be creditworthy pursuant to the
guidelines and/or standards reviewed or established by the Board of
Trustees (the "Trustees"). Risks may arise from the potential
inability of counterparties to honor the terms of the repurchase
agreement. Accordingly, the Fund could receive less than the
repurchase price on the sale of collateral securities.

INVESTMENT INCOME, EXPENSES AND DISTRIBUTIONS

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

FEDERAL TAXES

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

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

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

USE OF ESTIMATES

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

OTHER

Investment transactions are accounted for on the trade date.

SHARES OF BENEFICIAL INTEREST

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

Transactions in shares were as follows:

                  REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Shareholders and Board of Trustees of
MONEY MARKET OBLIGATIONS TRUST

(Treasury Obligations Fund):

We have audited the accompanying statement of assets and liabilities
of Treasury Obligations Fund (an investment portfolio of Money Market
Obligations Trust, a Massachusetts business trust), including the
schedule of portfolio investments, as of July 31, 1997, the related
statement of operations for the year then ended, the statement of
changes in net assets for each of the two years in the period then
ended, and the financial highlights for the periods presented. These
financial statements and financial highlights are the responsibility
of the Trust's management. Our responsibility is to express an opinion
on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements
and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts
and disclosures in the financial statements. Our procedures included
confirmation of securities owned as of July 31, 1997, by
correspondence with the custodian. An audit also includes assessing
the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements and financial highlights
referred to above present fairly, in all material respects, the
financial position of Treasury Obligations Fund (an investment
portfolio of Money Market Obligations Trust) as of July 31, 1997, the
results of its operations for the year then ended, the changes in its
net assets for each of the two years in the period then ended, and its
financial highlights for the periods presented, in conformity with
generally accepted accounting principles.

                            GENERAL INFORMATION

The Trust was established as a Massachusetts business trust under a
Declaration of Trust dated October 3, 1988. The Declaration of Trust
permits the Trust to offer separate series of shares representing
interests in separate portfolios of securities. The shares in any one
portfolio may be offered in separate classes. With respect to this
Fund, as of the date of this prospectus, the Board of Trustees (the
"Trustees") has established three classes of shares known as
Institutional Shares, Institutional Service Shares, and Institutional
Capital Shares. This prospectus relates only to Institutional Capital
Shares of the Fund, which are designed primarily for financial
institutions, financial intermediaries and institutional investors as
a convenient means of accumulating an interest in a professionally
managed portfolio investing in short-term U.S. Treasury securities. A
minimum initial investment of $1,000,000 over a one-year period is
required.

The Fund attempts to stabilize the value of a share at $1.00. Shares
are currently sold and redeemed at that price.

                           INVESTMENT INFORMATION

INVESTMENT OBJECTIVE

The investment objective of the Fund is current income consistent with
stability of principal. This investment objective cannot be changed
without shareholder approval. While there is no assurance that the
Fund will achieve its investment objective, it endeavors to do so by
complying with the diversification and other requirements of Rule 2a-7
under the Investment Company Act of 1940 which regulates money market
mutual funds and by following the investment policies described in
this prospectus.

INVESTMENT POLICIES

The Fund pursues its investment objective by investing only in a
portfolio of U.S. Treasury securities maturing in 13 months or less.
The average maturity of the securities in the Fund's portfolio,
computed on a dollar-weighted basis, will be 90 days or less. Unless
indicated otherwise, the investment policies may be changed by the
Trustees without shareholder approval. Shareholders will be notified
before any material change in these policies becomes effective.

ACCEPTABLE INVESTMENTS

The Fund invests only in U.S. Treasury securities, which are fully
guaranteed as to principal and interest by the United States.

REPURCHASE AGREEMENTS

Certain securities in which the Fund invests may be purchased pursuant
to repurchase agreements. Repurchase agreements are arrangements in
which banks, broker/dealers, and other recognized financial
institutions sell securities to the Fund and agree at the time of sale
to repurchase them at a mutually agreed upon time and price. To the
extent that the seller does not repurchase the securities from the
Fund, the Fund could receive less than the repurchase price on any
sale of such securities.

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

The Fund may purchase securities on a when-issued or delayed delivery
basis. These transactions are arrangements in which the Fund purchases
securities with payment and delivery scheduled for a future time. The
seller's failure to complete these transactions may cause the Fund to
miss a price or yield considered to be advantageous. Settlement dates
may be a month or more after entering into these transactions, and the
market values of the securities purchased may vary from the purchase
prices.

The Fund may dispose of a commitment prior to settlement if the
adviser deems it appropriate to do so. In addition, the Fund may enter
into transactions to sell its purchase commitments to third parties at
current market values and simultaneously acquire other commitments to
purchase similar securities at later dates. The Fund may realize
short-term profits or losses upon the sale of such commitments.

LENDING OF PORTFOLIO SECURITIES

In order to generate additional income, the Fund may lend its
portfolio securities on a short-term or long-term basis, or both, to
broker/dealers, banks, or other institutional borrowers of securities.
The Fund will only enter into loan arrangements with broker/dealers,
banks, or other institutions which the adviser has determined are
creditworthy under guidelines established by the Fund's Trustees and
will receive collateral at all times equal to at least 100% of the
value of the securities loaned. There is the risk that when lending
portfolio securities, the securities may not be available to the Fund
on a timely basis and the Fund may, therefore, lose the opportunity to
sell the securities at a desirable price. In addition, in the event
that a borrower of securities would file for bankruptcy or become
insolvent, disposition of the securities may be delayed pending court
action.

INVESTMENT LIMITATIONS

The Fund will not borrow money or pledge securities except, under
certain circumstances, the Fund may borrow up to one-third of the
value of its total assets and pledge up to 15% of the value of those
assets to secure such borrowings.

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

The Fund will not invest more than 10% of its net assets in illiquid
securities, including repurchase agreements providing for settlement
in more than seven days after notice.

                              FUND INFORMATION

MANAGEMENT OF THE FUND

BOARD OF TRUSTEES

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

INVESTMENT ADVISER

Investment decisions for the Fund are made by Federated Management,
the Fund's investment adviser, subject to direction by the Trustees.
The adviser continually conducts investment research and supervision
for the Fund and is responsible for the purchase and sale of portfolio
instruments.

ADVISORY FEES

The adviser receives an annual investment advisory fee equal to 0.20%
of the Fund's average daily net assets. The adviser may voluntarily
choose to waive a portion of its fee or reimburse other expenses of
the Fund, but reserves the right to terminate such waiver or
reimbursement at any time at its sole discretion.

ADVISER'S BACKGROUND

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

Federated Management and other subsidiaries of Federated Investors
serve as investment advisers to a number of investment companies and
private accounts. Certain other subsidiaries also provide
administrative services to a number of investment companies. With over
$110 billion invested across over 300 funds under management and/or
administration by its subsidiaries, as of December 31, 1996, Federated
Investors is one of the largest mutual fund investment managers in the
United States. With more than 2,000 employees, Federated continues to
be led by the management who founded the company in 1955. Federated
funds are presently at work in and through 4,500 financial
institutions nationwide.

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

DISTRIBUTION OF INSTITUTIONAL CAPITAL SHARES

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

Federated Investors.

SHAREHOLDER SERVICES

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

SUPPLEMENTAL PAYMENTS TO FINANCIAL INSTITUTIONS

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

ADMINISTRATION OF THE FUND

ADMINISTRATIVE SERVICES

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

MAXIMUM                      AVERAGE AGGREGATE
  FEE                        DAILY NET ASSETS

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

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

                              NET ASSET VALUE

The Fund attempts to stabilize the net asset value of shares at $1.00
by valuing the portfolio securities using the amortized cost method.
The net asset value per share is determined by subtracting liabilities
attributable to Institutional Capital Shares from the value of Fund
assets attributable to Institutional Capital Shares, and dividing the
remainder by the number of Institutional Capital Shares outstanding.
The Fund cannot guarantee that its net asset value will always remain
at $1.00 per share.

The net asset value is determined at 5:00 p.m. (Eastern time), Monday
through Friday, except on New Year's Day, Martin Luther King Day,
Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor
Day, Thanksgiving Day, and Christmas Day.

                           HOW TO PURCHASE SHARES

Shares are sold at their net asset value, without a sales charge, next
determined after an order is received, on days on which the New York
Stock Exchange is open for business. Shares may be purchased either by
wire or by check. The Fund reserves the right to reject any purchase
request.

To make a purchase, open an account by calling Federated Securities
Corp. Information needed to establish the account will be taken by
telephone. The minimum initial investment is $1,000,000. However, an
account may be opened with a smaller amount as long as the minimum is
reached within one year of opening the account. Financial institutions
may impose different minimum investment requirements on their
customers.

PURCHASING SHARES BY WIRE

Shares may be purchased by Federal Reserve wire by calling the Fund
before 5:00 p.m. (Eastern time) to place an order. The order is
considered received immediately. Payment by federal funds must be
received before 5:00 p.m. (Eastern time) that day. Federal funds
should be wired as follows: Federated Shareholder Services Company,
c/o State Street Bank and Trust Company, Boston, MA; Attention:
EDGEWIRE; For Credit to: Treasury Obligations Fund--Institutional
Capital Shares; Fund Number (this number can be found on the account
statement or by contacting the Fund); Group Number or Order Number;
Nominee or Institution Name; and ABA Number 011000028. Shares cannot
be purchased by wire on holidays when wire transfers are restricted.
Questions on wire purchases should be directed to your shareholder
services representative at the telephone number listed on your account
statement.

PURCHASING SHARES BY CHECK

Shares may be purchased by sending a check to Federated Shareholder
Services Company, P.O. Box 8600, Boston, MA 02266-8600. The check
should be made payable to: Treasury Obligations Fund -- Institutional
Capital Shares. 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.

INVEST-BY-PHONE

Once an account has been opened, a shareholder may use invest-by-phone
for investments if an authorization form has been filed with Federated
Shareholder Services Company, the transfer agent for shares of the
Fund. Approximately two weeks after sending the form to Federated
Shareholder Services Company, the shareholder may call Federated
Shareholder Services Company to purchase shares. Federated Shareholder
Services Company will send a request for monies to the shareholder's
commercial bank, savings bank, or credit union ("bank") via the
Automated Clearing House. The shareholder's bank, which must be an
Automated Clearing House member, will then forward the monies to
Federated Shareholder Services Company. The purchase is normally
entered the next business day after the initial phone request. For
further information and an application, call the Fund.

                            HOW TO REDEEM SHARES

Shares are redeemed at their net asset value next determined after
Federated Shareholder Services Company receives the redemption
request. Redemptions will be made on days on which the Fund computes
its net asset value. Redemption requests must be received in proper
form and can be made as described below.

REDEEMING SHARES BY TELEPHONE

Redemptions in any amount may be made by calling the Fund provided the
Fund has a properly completed authorization form. These forms can be
obtained from Federated Securities Corp. Proceeds from redemption
requests received before 5:00 p.m. (Eastern time) will be wired the
same day to the shareholder's account at a domestic commercial bank
which is a member of the Federal Reserve System, but will not include
that day's dividend. Proceeds from redemption requests on holidays
when wire transfers are restricted will be wired the following
business day. Questions about telephone redemptions on days when wire
transfers are restricted should be directed to your shareholder
services representative at the telephone number listed on your account
statement.

Telephone instructions may be recorded and if reasonable procedures
are not followed by the Fund, it may be liable for losses due to
unauthorized or fraudulent telephone instructions.

In the event of drastic economic or market changes, a shareholder may
experience difficulty in redeeming by telephone. If this occurs,
"Redeeming Shares by Mail" should be considered. If at any time the
Fund shall determine it necessary to terminate or modify the telephone
redemption privilege, shareholders would be promptly notified.

REDEEMING SHARES BY MAIL

Shares may be redeemed in any amount by mailing a written request to:
Federated Shareholder Services Company, P.O. Box 8600, Boston, MA
02266-8600. If share certificates have been issued, they should be
sent unendorsed with the written request by registered or certified
mail to the address noted above.

The written request should state: the Fund name and the class
designation; the account name as registered with the Fund; the account
number; and the number of shares to be redeemed or the dollar amount
requested. All owners of the account must sign the request exactly as
the shares are registered. Normally, a check for the proceeds is
mailed within one business day, but in no event more than seven days,
after the receipt of a proper written redemption request. Dividends
are paid up to and including the day that a redemption request is
processed.

Shareholders requesting a redemption of any amount to be sent to an
address other than that on record with the Fund or a redemption
payable other than to the shareholder of record must have their
signatures guaranteed by a commercial or savings bank, trust company
or savings association whose deposits are insured by an organization
which is administered by the Federal Deposit Insurance Corporation; a
member firm of a domestic stock exchange; or any other "eligible
guarantor institution," as defined in the Securities Exchange Act of
1934. The Fund does not accept signatures guaranteed by a notary
public.

                       ACCOUNT AND SHARE INFORMATION

DIVIDENDS

Dividends are declared daily and paid monthly. Dividends are
automatically reinvested on payment dates in additional shares of the
Fund unless cash payments are requested by writing to the Fund. Shares
purchased by wire before 5:00 p.m. (Eastern time) begin earning
dividends that day. Shares purchased by check begin earning dividends
the day after the check is converted into federal funds.

CAPITAL GAINS

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 will distribute in cash or
additional shares any realized net long-term capital gains at least
once every 12 months.

CONFIRMATIONS AND ACCOUNT STATEMENTS

Shareholders will receive detailed confirmations of transactions
(except for systematic program transactions). In addition,
shareholders will receive periodic statements reporting all account
activity, including dividends paid. The Fund will not issue share
certificates.

ACCOUNTS WITH LOW BALANCES

Due to the high cost of maintaining accounts with low balances, the
Fund may redeem shares in any account, except accounts maintained by
retirement plans, and pay the proceeds to the shareholder if the
account balance falls below a required minimum value of $1,000,000 due
to shareholder redemptions. Before shares are redeemed to close an
account, the shareholder is notified in writing and allowed 30 days to
purchase additional shares to meet the minimum requirement.

VOTING RIGHTS

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

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

As of September 4, 1997, Excelsior-Henderson Motorcycle Manufacturing
Company, 607 W. Travelers Trail, Burnsville, MN, owned 63.46% of the
voting securities of the Fund, and, therefore, may, for certain
purposes, be deemed to control the Fund and be able to affect the
outcome of certain matters presented for a vote of shareholders.

                              TAX INFORMATION

FEDERAL INCOME TAX

The Fund will pay no federal income tax because it expects to meet
requirements of the Internal Revenue Code applicable to regulated
investment companies and to receive the special tax treatment afforded
to such companies. The Fund will be treated as a single, separate
entity for federal income tax purposes so that income (including
capital gains) and losses realized by the Trust's other portfolios
will not be combined for tax purposes with those realized by the Fund.

Unless otherwise exempt, shareholders are required to pay federal
income tax on any dividends and other distributions received. This
applies whether dividends and distributions are received in cash or as
additional shares.

STATE AND LOCAL TAXES

In the opinion of Houston, Donnelly & Meck, counsel to the Trust, Fund
shares may be subject to personal property taxes imposed by counties,
municipalities, and school districts in Pennsylvania to the extent
that the portfolio securities in the Fund would be subject to such
taxes if owned directly by residents of those jurisdictions.

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

                          OTHER CLASSES OF SHARES

The Fund also offers other classes. Institutional Shares are sold at
net asset value primarily to entities holding shares in an agency or
fiduciary capacity, financial institutions, financial intermediaries
and institutional investors and are subject to a minimum initial
investment of $1,000,000. Institutional Service Shares are sold at net
asset value primarily to financial institutions, financial
intermediaries and institutional investors and are subject to a
minimum initial investment of $1,000,000.

All classes are subject to certain of the same expenses.

Institutional Shares are distributed with no 12b-1 Plan but are
subject to shareholder services fees.

Institutional Service Shares are distributed with no 12b-1 Plan but
are subject to shareholder services fees.

Expense differences between classes may affect the performance of each
class.

To obtain more information and a prospectus for any other class,
investors may call 1-800-341-7400.

                          PERFORMANCE INFORMATION

From time to time, the Fund advertises its yield, effective yield and
total return. The performance figures will be calculated separately
for each class of shares.

Yield represents the annualized rate of income earned on an investment
over a seven-day period. It is the annualized dividends earned during
the period on an investment shown as a percentage of the investment.
The effective yield is calculated similarly to the yield, but when
annualized, the income earned by an investment is assumed to be
reinvested daily. The effective yield will be slightly higher than the
yield because of the compounding effect of this assumed reinvestment.

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

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

                               JULY 31, 1997

ORGANIZATION

Money Market Obligations Trust (the "Trust") is registered under the
Investment Company Act of 1940, as amended (the "Act") as an open-end,
management investment company. The Trust consists of six portfolios.
The financial statements included herein are only those of Treasury
Obligations Fund (the "Fund"), a diversified portfolio. The financial
statements of the other portfolios are presented separately. The
assets of each portfolio are segregated and a shareholder's interest
is limited to the portfolio in which shares are held. The investment
objective of the Fund is current income consistent with stability of
principal.

The Fund offers three classes of shares: Institutional Shares, Institutional
Service Shares, and Institutional Capital Shares. Effective April 14, 1997,
the Trust added Institutional Capital Shares.

SIGNIFICANT ACCOUNTING POLICIES

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

INVESTMENT VALUATIONS

The Fund uses the amortized cost method to value its portfolio
securities in accordance with Rule 2a-7 under the Act.

REPURCHASE AGREEMENTS

It is the policy of the Fund to require the custodian bank to take
possession, to have legally segregated in the Federal Reserve Book
Entry System, or to have segregated within the custodian bank's vault,
all securities held as collateral under repurchase agreement
transactions. Additionally, procedures have been established by the
Fund to monitor, on a daily basis, the market value of each repurchase
agreement's collateral to ensure that the value of collateral at least
equals the repurchase price to be paid under the repurchase agreement
transaction.

The Fund will only enter into repurchase agreements with banks and
other recognized financial institutions, such as broker/dealers, which
are deemed by the Fund's adviser to be creditworthy pursuant to the
guidelines and/or standards reviewed or established by the Board of
Trustees (the "Trustees"). Risks may arise from the potential
inability of counterparties to honor the terms of the repurchase
agreement. Accordingly, the Fund could receive less than the
repurchase price on the sale of collateral securities.

INVESTMENT INCOME, EXPENSES AND DISTRIBUTIONS

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

FEDERAL TAXES

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

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

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

USE OF ESTIMATES

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

OTHER

Investment transactions are accounted for on the trade date.

SHARES OF BENEFICIAL INTEREST

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

                  REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Shareholders and Board of Trustees of
MONEY MARKET OBLIGATIONS TRUST

(Treasury Obligations Fund):

We have audited the accompanying statement of assets and liabilities
of Treasury Obligations Fund (an investment portfolio of Money Market
Obligations Trust, a Massachusetts business trust), including the
schedule of portfolio investments, as of July 31, 1997, the related
statement of operations for the year then ended, the statement of
changes in net assets for each of the two years in the period then
ended, and the financial highlights for the periods presented. These
financial statements and financial highlights are the responsibility
of the Trust's management. Our responsibility is to express an opinion
on these financial statements and financial highlights based on our
audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements
and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts
and disclosures in the financial statements. Our procedures included
confirmation of securities owned as of July 31, 1997, by
correspondence with the custodian. An audit also includes assessing
the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements and financial highlights
referred to above present fairly, in all material respects, the
financial position of Treasury Obligations Fund (an investment
portfolio of Money Market Obligations Trust) as of July 31, 1997, the
results of its operations for the year then ended, the changes in its
net assets for each of the two years in the period then ended, and its
financial highlights for the periods presented, in conformity with
generally accepted accounting principles.

INVESTMENT POLICIES

Unless indicated otherwise, the policies described below may be
changed by the Board of Trustees (the "Trustees") without shareholder
approval. Shareholders will be notified before any material change in
these policies becomes effective.

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

These transactions are made to secure what is considered to be an
advantageous price or yield for the Fund. No fees or other expenses,
other than normal transaction costs, are incurred. However, liquid
assets of the Fund in a dollar amount sufficient to make payment for
the securities to be purchased are: segregated on the Fund's records
at the trade date; marked to market daily; and maintained until the
transaction is settled. The Fund does not intend to engage in
when-issued and delayed delivery transactions to an extent that would
cause the segregation of more than 20% of the total value of its
assets.

REPURCHASE AGREEMENTS

The Fund believes that under the regular procedures normally in effect
for custody of the Fund's portfolio securities subject to repurchase
agreements, a court of competent jurisdiction would rule in favor of
the Fund and allow retention or disposition of such securities. The
Fund will only enter into repurchase agreements with banks and other
recognized financial institutions, such as broker/dealers, which are
deemed by the Fund's adviser to be creditworthy pursuant to guidelines
established by the Trustees.

LENDING OF PORTFOLIO SECURITIES

The collateral received when the Fund lends portfolio securities must
be valued daily and, should the market value of the loaned securities
increase, the borrower must furnish additional collateral to the Fund.
During the time portfolio securities are on loan, the borrower pays
the Fund any dividends or interest paid on such securities. Loans are
subject to termination at the option of the Fund or the borrower. The
Fund may pay reasonable administrative and custodial fees in
connection with a loan and may pay a negotiated portion of the
interest earned on the cash or equivalent collateral to the borrower
or placing broker.

INVESTMENT LIMITATIONS

SELLING SHORT AND BUYING ON MARGIN

The Fund will not sell any securities short or purchase any securities
on margin but may obtain such short-term credits as are necessary for
clearance of transactions.

ISSUING SENIOR SECURITIES AND BORROWING MONEY

The Fund will not issue senior securities except that the Fund may
borrow money in amounts up to one-third of the value of its total
assets, including the amounts borrowed.

The Fund will not borrow money for investment leverage, but rather as
a temporary, extraordinary, or emergency measure or to facilitate
management of the portfolio by enabling the Fund to meet redemption
requests when the liquidation of portfolio securities is deemed to be
inconvenient or disadvantageous. The Fund will not purchase any
securities while borrowings in excess of 5% of the value of its total
assets are outstanding.

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 15% of the value of total assets of the
Fund at the time of the pledge.

LENDING CASH OR SECURITIES

The Fund will not lend any of its assets, except portfolio securities.
This shall not prevent the Fund from purchasing or holding bonds,
debentures, notes, certificates of indebtedness or other debt
securities, entering into repurchase agreements, or engaging in
transactions permitted by its investment objective, policies, and
limitations or Declaration of Trust.

INVESTING IN COMMODITIES

The Fund will not purchase or sell commodities, commodity contracts,
or commodity futures contracts.

INVESTING IN REAL ESTATE

The Fund will not purchase or sell real estate, including limited
partnership interests.

UNDERWRITING

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

CONCENTRATION OF INVESTMENTS

The Fund will not invest 25% or more of the value of its total assets
in any one industry. However, the Fund may invest 25% or more of the
value of its total assets in cash, cash items, or 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.

DIVERSIFICATION OF INVESTMENTS

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, or 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) if as a result more than 5% of the value of its total
assets would be invested in the securities of that issuer, or if it
would own more than 10% of the outstanding voting securities of that
issuer.

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

INVESTING IN ILLIQUID SECURITIES

The Fund will not invest more than 10% of the value of its net assets
in illiquid securities, including certain restricted securities not
determined to be liquid under criteria established by the Trustees and
repurchase agreements providing for settlement in more than seven days
after notice.

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.

INVESTING FOR CONTROL

The Fund will not invest in securities of a company for the purpose of
exercising control or management.

INVESTING IN OPTIONS

The Fund will not invest in puts, calls, straddles, spreads, or any
combination of them.

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.

The Fund did not borrow money or pledge securities in excess of 5% of
the value of its net assets during the last fiscal year and has no
present intent to do so during the coming fiscal year.

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, which regulates money market mutual funds.
The Fund will determine the effective maturity of its investments
according to Rule 2a-7. The Fund may change these operational policies
to reflect changes in the laws and regulations without the approval of
its shareholders.

TRUSTEE LIABILITY

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

INVESTMENT ADVISORY SERVICES

INVESTMENT ADVISER

The Fund's investment adviser is Federated Management. It is a subsidiary of
Federated Investors. All the voting securities of Federated Investors are
owned by a trust, the trustees of which are John F. Donahue, his wife and
his son, J. Christopher Donahue.

The adviser shall not be liable to the Trust, the Fund, or any
shareholder of the Fund for any losses that may be sustained in the
purchase, holding, or sale of any security or for anything done or
omitted by it, except acts or omissions involving willful misfeasance,
bad faith, gross negligence, or reckless disregard of the duties
imposed upon it by its contract with the Fund.

ADVISORY FEES

For its advisory services, Federated Management receives an annual
investment advisory fee as described in the prospectus. For the fiscal
years ended July 31, 1997, 1996, and 1995, the adviser earned
$13,886,919, $11,303,978, and $6,522,177, respectively, of which
$6,879,101, $5,936,217, and $3,742,710, respectively, were waived.

BROKERAGE TRANSACTIONS

When selecting brokers and dealers to handle the purchase and sale of
portfolio instruments, the adviser looks for prompt execution of the
order at a favorable price. In working with dealers, the adviser will
generally use those who are recognized dealers in specific portfolio
instruments, except when a better price and execution of the order can
be obtained elsewhere. The adviser makes decisions on portfolio
transactions and selects brokers and dealers subject to guidelines
established by the Trustees. The adviser may select brokers and
dealers who offer brokerage and research services. These services may
be furnished directly to the Fund or to the adviser and may include:
advice as to the advisability of investing in securities; security
analysis and reports; economic studies; industry studies; receipt of
quotations for portfolio evaluations; and similar services. Research
services provided by brokers and dealers may be used by the adviser or
its affiliates in advising the Fund and other accounts. To the extent
that receipt of these services may supplant services for which the
adviser or its affiliates might otherwise have paid, it would tend to
reduce their expenses. The adviser and its affiliates exercise
reasonable business judgment in selecting brokers who offer brokerage
and research services to execute securities transactions. They
determine in good faith that commissions charged by such persons are
reasonable in relationship to the value of the brokerage and research
services provided. During the fiscal years ended July 31, 1997, 1996,
and 1995, the Fund paid no brokerage commissions.

Although investment decisions for the Fund are made independently from
those of the other accounts managed by the adviser, investments of the
type the Fund may make may also be made by those other accounts. When
the Fund and one or more other accounts managed by the adviser are
prepared to invest in, or desire to dispose of, the same security,
available investments or opportunities for sales will be allocated in
a manner believed by the adviser to be equitable to each. In some
cases, this procedure may adversely affect the price paid or received
by the Fund or the size of the position obtained or disposed of by the
Fund. In other cases, however, it is believed that coordination and
the ability to participate in volume transactions will be to the
benefit of the Fund.

OTHER SERVICES

FUND ADMINISTRATION

Federated Services Company, a subsidiary of Federated Investors,
provides administrative personnel and services to the Fund for a fee
as described in the prospectus. From March 1, 1994 to March 1, 1996,
Federated Administrative Services, a subsidiary of Federated
Investors, served as the Fund's Administrator. For purposes of this
Statement of Additional Information, Federated Services Company and
Federated Administrative Services may hereinafter collectively be
referred to as the "Administrators." For the fiscal years ended July
31, 1997, 1996, and 1995, the Administrators earned $5,244,250,
$4,274,511, and $2,468,644, respectively.

CUSTODIAN AND PORTFOLIO ACCOUNTANT

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

TRANSFER AGENT

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

INDEPENDENT PUBLIC ACCOUNTANTS

The independent public accountants for the Fund are Arthur Andersen
LLP, Pittsburgh, PA.

SHAREHOLDER SERVICES

This arrangement permits the payment of fees to Federated Shareholder
Services to cause services to be provided which are necessary for the
maintenance of shareholder accounts and to encourage personal services
to shareholders by a representative who has knowledge of the
shareholder's particular circumstances and goals. These activities and
services may include but are not limited to providing office space,
equipment, telephone facilities, and various clerical, supervisory,
computer, and other personnel as necessary or beneficial to establish
and maintain shareholder accounts and records; processing purchase and
redemption transactions and automatic investments of client account
cash balances; answering routine client inquiries; and assisting
clients in changing dividend options, account designations, and
addresses.

By adopting the Shareholder Services Agreement, the Trustees expect
that the Fund will benefit by: (1) providing personal services to
shareholders; (2) investing shareholder assets with a minimum of delay
and administrative detail; (3) enhancing shareholder recordkeeping
systems; and (4) responding promptly to shareholders' requests and
inquiries concerning their accounts.

For the fiscal year ended July 31, 1997, the Fund earned shareholder
service fees on behalf of the Institutional Shares, Institutional
Service Shares, and Institutional Capital Shares in the amounts of
$12,135,054, $5,214,861, and $8,734, respectively, $0, $5,214,861, and
$3,494 of which were paid to financial institutions, respectively.

DETERMINING NET ASSET VALUE

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 Rule
2a-7 (the "Rule") promulgated by the Securities and Exchange
Commission under the Investment Company Act of 1940. 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.

REDEMPTION IN KIND

The Fund is obligated to redeem shares solely in cash up to $250,000
or 1% of the Fund's net asset value, whichever is less, for any one
shareholder within a 90-day period. Any redemption beyond this amount
will also be in cash unless the Trustees determine that further
payments should be in kind. In such cases, the Fund will pay all or a
portion of the remainder of the redemption in portfolio instruments
valued in the same way as the Fund determines net asset value. The
portfolio instruments will be selected in a manner that the Trustees
deem fair and equitable. Redemption in kind is not as liquid as a cash
redemption. If redemption is made in kind, shareholders who sell these
securities could receive less than the redemption value and could
incur certain transaction costs.

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. These documents
require notice of this disclaimer to be given in each agreement,
obligation, or instrument the Trust or its Trustees enter into or
sign.

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.

THE FUND'S TAX STATUS

To qualify for the special tax treatment afforded to regulated
investment companies, the Fund must, among other requirements: derive
at least 90% of its gross income from dividends, interest, and gains
from the sale of securities; derive less than 30% of its gross income
from the sale of securities held less than three months; invest in
securities within certain statutory limits; and distribute to its
shareholders at least 90% of its net income earned during the year.

PERFORMANCE INFORMATION

Performance depends upon such variables as: portfolio quality; average
portfolio maturity; type of instruments in which the portfolio is
invested; changes in interest rates; changes in expenses; and the
relative amount of cash flow. To the extent that financial
institutions and broker/dealers charge fees in connection with
services provided in conjunction with an investment in shares of the
Fund, the performance will be reduced for those shareholders paying
those fees.

YIELD

The yield is calculated based upon the seven days ending on the day of
the calculation, called the "base period." This yield is computed 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.

For the seven-day period ended July 31, 1997, the yield for
Institutional Shares, Institutional Service Shares and Institutional
Capital Shares, respectively, was 5.46%, 5.21%, and 5.36%,
respectively.

EFFECTIVE YIELD

The effective yield is calculated by compounding the unannualized base
period return by: adding 1 to the base period return; raising the sum
to the 365/7th power; and subtracting 1 from the result.

For the seven-day period ended July 31, 1997, the effective yield for
Institutional Shares, Institutional Service Shares and Institutional
Capital Shares, respectively, was 5.61%, 5.35%, and 5.51%,
respectively.

TOTAL RETURN

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

Prior to the creation of separate classes of shares, for the one-year
and five-year periods ended July 31, 1997 and for the period from
December 12, 1989 (start of performance) through July 31, 1997, the
average annual total returns were 5.36%, 4.57% and 5.20%,
respectively, for Institutional Shares.

For the one-year period ended July 31, 1997 and for the period from
July 5, 1994 (date of initial public offering) through July 31, 1997,
the average annual total returns were 5.10% and 5.17%, respectively,
for Institutional Service Shares.

Cumulative total return reflects the total performance over a specific
period of time. For the period from April 14, 1997 (date of initial
public investment) through July 31, 1997, the cumulative total return
for Institutional Capital Shares was 1.58%. These total returns are
representative of only 4 months of activity since the date of initial
public investment.

GENERAL INFORMATION

The Trust was established as a Massachusetts business trust under a
Declaration of Trust dated October 3, 1988. The Declaration of Trust
permits the Trust to offer separate series of shares representing
interests in separate portfolios of securities. The shares in any one
portfolio may be offered in separate classes. With respect to this
Fund, as of the date of this prospectus, the Board of Trustees (the
"Trustees") has established two classes of shares known as Cash II
Shares and Institutional Service Shares. This prospectus relates only
to Cash II Shares of the Fund, which are designed primarily for the
retail customers of financial institutions as a convenient means of
accumulating an interest in a professionally managed portfolio
investing in short-term money market securities. A minimum initial
investment of $25,000 over a 90-day period is required except for
retirement plans.

The Fund attempts to stabilize the value of a share at $1.00. Shares
are currently sold and redeemed at that price.

INVESTMENT INFORMATION

INVESTMENT OBJECTIVE

The investment objective of the Fund is stability of principal and
current income consistent with stability of principal. This investment
objective cannot be changed without shareholder approval. While there
is no assurance that the Fund will achieve its investment objective,
it endeavors to do so by complying with the diversification and other
requirements of Rule 2a-7 under the Investment Company Act of 1940
which regulates money market mutual funds and by following the
investment policies described in this prospectus.

INVESTMENT POLICIES

The Fund pursues its investment objective by investing in a portfolio
of money market instruments maturing in 13 months or less. The average
maturity of the money market instruments in the Fund's portfolio,
computed on a dollar-weighted basis, will be 90 days or less. Unless
indicated otherwise, the investment policies may not be changed by the
Trustees without shareholder approval.

ACCEPTABLE INVESTMENTS

The Fund invests in high quality money market instruments that are
either rated in the highest short-term rating category by one or more
nationally recognized statistical rating organizations ("NRSROs") or
are of comparable quality to securities having such ratings. Examples
of these instruments include, but are not limited to:

   * instruments of domestic and foreign banks and savings and loans
     (such as certificates of deposit, demand and time deposits,
     savings shares, and bankers' acceptances) if they have capital,
     surplus, and undivided profits of over $100,000,000, or if the
     principal amount of the instrument is insured by the Bank
     Insurance Fund ("BIF") which is administered by the Federal
     Deposit Insurance Corporation ("FDIC") or the Savings Association
     Insurance Fund ("SAIF") which is administered by the FDIC. These
     instruments may include Eurodollar Certificates of Deposit
     ("ECDs"), Yankee Certificates of Deposit ("Yankee CDs"), and
     Eurodollar Time Deposits ("ETDs");

   * commercial paper rated A-1 by Standard & Poor's Ratings Group,
     Prime-1 by Moody's Investors Service, Inc., or F-1 by Fitch
     Investors Service, and unrated but of comparable quality,
     including Canadian Commercial Paper ("CCPs") and Europaper.

   * marketable obligations issued or guaranteed by the U.S. government, its
     agencies, or instrumentalities; and

   * repurchase agreements.

The Fund invests only in instruments denominated and payable in U.S.
dollars.

REPURCHASE AGREEMENTS

Certain securities in which the Fund invests may be purchased pursuant
to repurchase agreements. Repurchase agreements are arrangements in
which banks, broker/dealers, and other recognized financial
institutions sell U. S. government securities or certificates of
deposit to the Fund and agree, at the time of sale, to repurchase them
at a mutually agreed upon time and price within one year from the date
of acquisition. The Fund or its custodian will take possession of the
securities subject to repurchase agreements and these securities will
be marked to market daily. To the extent that the original seller does
not repurchase the securities from the Fund, the Fund could receive
less than the repurchase price on any sale of such securities.

CREDIT ENHANCEMENT

Certain of the Fund's acceptable investments may be credit-enhanced by
a guaranty, letter of credit, or insurance. Any bankruptcy,
receivership, default or change in the credit quality of the party
providing the credit enhancement will adversely affect the quality and
marketability of the underlying security and could cause losses to the
Fund and affect its share price.

DEMAND FEATURES

As a matter of non-fundamental policy, the Fund may acquire securities
that are subject to puts and standby commitments ("demand features")
to purchase the securities at their principal amount (usually with
accrued interest) within a fixed period (usually seven days) following
a demand by the Fund. The demand feature may be issued by the issuer
of the underlying securities, a dealer in the securities, or by
another third party, and may not be transferred separately from the
underlying security. The Fund uses these arrangements to provide the
Fund with liquidity and not to protect against changes in the market
value of the underlying securities. The bankruptcy, receivership, or
default by the issuer of the demand feature, or a default on the
underlying security or other event that terminates the demand feature
before its exercise, will adversely affect the liquidity of the
underlying security. Demand features that are exercisable even after a
payment default on the underlying security may be treated as a form of
credit enhancement.

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

The Fund may purchase short-term U.S. government obligations on a
when-issued or delayed delivery basis. These transactions are
arrangements in which the Fund purchases securities with payment and
delivery scheduled for a future time. The Fund engages in when-issued
and delayed delivery transactions only for the purpose of acquiring
portfolio securities consistent with the Fund's investment objective
and policies, not for investment leverage. In when-issued and delayed
delivery transactions, the Fund relies on the seller to complete the
transaction. The seller's failure to deliver the securities may cause
the Fund to miss a price or yield considered to be advantageous.
Settlement dates may be a month or more after entering into these
transactions, and the market values of the securities purchased may
vary from the purchase prices.

As a matter of operating policy, the Fund may dispose of a commitment
prior to settlement if the adviser deems it appropriate to do so. In
addition, the Fund may enter into transactions to sell its purchase
commitments to third parties at current market values and
simultaneously acquire other commitments to purchase similar
securities at later dates. The Fund may realize short-term profits or
losses upon the sale of such commitments.

RESTRICTED AND ILLIQUID SECURITIES

The Fund may invest in restricted securities and as a matter of
fundamental investment policy which may not be changed without
shareholder approval, will limit such investments to 10% of its net
assets. This restriction is not applicable to commercial paper issued
under Section 4(2) of the Securities Act of 1933. Restricted
securities are any securities in which the Fund may invest pursuant to
its investment objective and policies but which are subject to
restrictions on resale under federal securities law. In addition, as a
matter of fundamental policy, the Fund will limit investments in
illiquid securities, including restricted securities determined not to
be liquid and repurchase agreements providing for settlement in more
than seven days after notice, to 10% of its net assets. Certain
instruments in which the Fund may invest, such as ETDs and repurchase
agreements with maturities of more than seven days, could be
considered illiquid.

INVESTMENT RISKS

ECDs, ETDs, Yankee CDs, Canadian Commercial Paper, and Europaper are
subject to different risks than domestic obligations of domestic banks
or corporations. Examples of these risks include international
economic and political developments, foreign governmental restrictions
that may adversely affect the payment of principal or interest,
foreign withholding or other taxes on interest income, difficulties in
obtaining or enforcing a judgment against the issuing entity, and the
possible impact of interruptions in the flow of international currency
transactions. Risks may also exist for ECDs, ETDs, and Yankee CDs
because the banks issuing these instruments, or their domestic or
foreign branches, are not necessarily subject to the same regulatory
requirements that apply to domestic banks, such as reserve
requirements, loan limitations, examinations, accounting, auditing,
recordkeeping, and the public availability of information. These
factors will be carefully considered by the Fund's adviser in
selecting investments for the Fund.

INVESTMENT LIMITATIONS

The Fund will not borrow money directly or through reverse repurchase
agreements (arrangements in which the Fund sells a money market
instrument for a percentage of its cash value with an agreement to buy
it back on a set date) or pledge securities except, under certain
circumstances, the Fund may borrow up to one-third of the value of its
total assets and pledge up to 10% of the value of its total assets to
secure such borrowings. These investment limitations cannot be changed
without shareholder approval.

FUND INFORMATION

MANAGEMENT OF THE FUND

BOARD OF TRUSTEES

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

INVESTMENT ADVISER

Investment decisions for the Fund are made by Federated Management,
the Fund's investment adviser, subject to direction by the Trustees.
The adviser continually conducts investment research and supervision
for the Fund and is responsible for the purchase and sale of portfolio
instruments.

ADVISORY FEES

The adviser receives an annual investment advisory fee equal to 0.50%
of the Fund's average daily net assets. The adviser may voluntarily
choose to waive a portion of its fee or reimburse other expenses of
the Fund, but reserves the right to terminate such waiver or
reimbursement at any time at its sole discretion.

ADVISER'S BACKGROUND

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

Federated Management and other subsidiaries of Federated Investors
serve as investment advisers to a number of investment companies and
private accounts. Certain other subsidiaries also provide
administrative services to a number of investment companies. With over
$110 billion invested across over 300 funds under management and/or
administration by its subsidiaries, as of December 31, 1996, Federated
Investors is one of the largest mutual fund investment managers in the
United States. With more than 2,000 employees, Federated continues to
be led by the management who founded the company in 1955. Federated
funds are presently at work in and through 4,500 financial
institutions nationwide.

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

DISTRIBUTION OF CASH II SHARES

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

DISTRIBUTION PLAN AND SHAREHOLDER SERVICES

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

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

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

SUPPLEMENTAL PAYMENTS TO FINANCIAL INSTITUTIONS

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

ADMINISTRATION OF THE FUND

ADMINISTRATIVE SERVICES

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

 MAXIMUM         AVERAGE AGGREGATE
   FEE            DAILY NET ASSETS

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

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

NET ASSET VALUE

The Fund attempts to stabilize the net asset value of shares at $1.00
by valuing the portfolio securities using the amortized cost method.
The net asset value per share is determined by subtracting liabilities
attributable to Cash II Shares from the value of Fund assets
attributable to Cash II Shares, and dividing the remainder by the
number of Cash II Shares outstanding. The Fund cannot guarantee that
its net asset value will always remain at $1.00 per share.

The net asset value is determined at 5:00 p.m. (Eastern time), Monday
through Friday, except on New Year's Day, Martin Luther King Day,
Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor
Day, Thanksgiving Day, and Christmas Day.

HOW TO PURCHASE SHARES

Shares are sold at their net asset value, without a sales charge, next
determined after an order is received, on days which the New York
Stock Exchange is open for business. Shares may be purchased as
described below, either through a financial institution (such as a
bank or broker/dealer) or by wire or by check directly from the Fund,
with a minimum initial investment of $25,000 or more over a 90-day
period. Financial institutions may impose different minimum investment
requirements on their customers.

In connection with any sale, Federated Securities Corp. may from time
to time offer certain items of nominal value to any shareholder or
investor. The Fund reserves the right to reject any purchase request.
An account must be established at a financial institution or by
completing, signing, and returning the new account form available from
the Fund before shares can be purchased.

PURCHASING SHARES THROUGH A FINANCIAL INSTITUTION

Investors may purchase shares through a financial institution which
has a sales agreement with the distributor. Orders are considered
received when the Fund receives payment by wire or converts payment by
check from the financial institution into federal funds. It is the
financial institution's responsibility to transmit orders promptly.
Financial institutions may charge additional fees for their services.

PURCHASING SHARES BY WIRE

Shares may be purchased by wire by calling the Fund before 5:00 p.m.
Eastern time to place an order. The order is considered received
immediately. Payment by federal funds must be received before 5:00
p.m. Eastern time in order to begin earning dividends that same day.
Federal funds should be wired as follows: Federated Shareholder
Services Company, c/o State Street Bank and Trust Company, Boston, MA;
Attention: EDGEWIRE; For Credit to: Automated Cash Management
Trust--Cash II Shares; Fund Number (this number can be found on the
account statement or by contacting the Fund); Group Number or Order
Number; Nominee or Institution Name; and ABA Number 011000028. Shares
cannot be purchased by wire on holidays when wire transfers are
restricted. Questions on wire purchases should be directed to your
shareholder services representative at the telephone number listed on
your account statement.

PURCHASING SHARES BY CHECK

Shares may be purchased by sending a check to Federated Shareholder
Services Company, P.O. Box 8600, Boston, MA 02266-8600. The check
should be made payable to Automated Cash Management Trust--Cash II
Shares. Please include an account number on the check. 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.

INVEST-BY-PHONE

Once an account has been opened, a shareholder may use invest-by-phone
for investments if an authorization form has been filed with Federated
Shareholder Services Company, the transfer agent for shares of the
Fund. Approximately two weeks after sending the form to Federated
Shareholder Services Company, the shareholder may call Federated
Shareholder Services Company to purchase shares. Federated Shareholder
Services Company will send a request for monies to the shareholder's
commercial bank, savings bank, or credit union ("bank") via the
Automated Clearing House. The shareholder's bank, which must be an
Automated Clearing House member, will then forward the monies to
Federated Shareholder Services Company. The purchase is normally
entered the next business day after the initial phone request. For
further information and an application, call the Fund.

BY DIRECT DEPOSIT

Shareholders of the Fund may have their Social Security, Railroad
Retirement, VA Compensation or Pension, Civil Service Retirement, and
certain other retirement payments invested directly into their Fund
account. Shareholders must complete an application and file it with
Federated Shareholder Services Company prior to use of this program.
Allow 60 to 90 days for the application to be processed.

AUTOMATIC INVESTMENTS

Investors may establish accounts with their financial institutions to
have cash accumulations automatically invested in the Fund. The
investments may be made on predetermined dates or when the investor's
account reaches a certain level. Participating financial institutions
are responsible for prompt transmission of orders relating to the
program, and they may charge for their services. Investors should read
this prospectus along with the financial institution's agreement or
literature describing these services and fees.

SUBACCOUNTING SERVICES

Financial institutions are encouraged to open single master accounts.
A subaccounting system is available through the transfer agent to
minimize internal recordkeeping requirements. The transfer agent
charges a fee based on the level of subaccounting services rendered.
Financial institutions 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 provided which may be related
to the ownership of Fund shares. This prospectus should, therefore, be
read together with any agreement between the customer and the
financial institution with regard to the services provided, the fees
charged for those services, and any restrictions and limitations
imposed.

SPECIAL PURCHASE FEATURES

SYSTEMATIC INVESTMENT PROGRAM

A minimum of $100 can be automatically withdrawn periodically from the
shareholder's checking account at an Automated Clearing House ("ACH")
member and invested in Fund shares. Shareholders should contact their
financial institution or the Fund to participate in this program.

HOW TO REDEEM SHARES

Shares are redeemed at their net asset value next determined after
Federated Shareholder Services Company receives the redemption
request. Redemptions will be made on days on which the Fund computes
its net asset value. Redemption requests must be received in proper
form and can be made as described below.

REDEEMING SHARES THROUGH A FINANCIAL INSTITUTION

Shares may be redeemed by contacting the shareholder's financial
institution. Shares will be redeemed at the net asset value next
determined after Federated Shareholder Services Company receives the
redemption request. According to the shareholder's instructions,
redemption proceeds can be sent to the financial institution or to the
shareholder by check or by wire. The financial institution is
responsible for promptly submitting redemption requests and providing
proper written redemption instructions. Customary fees and commissions
may be charged by the financial institution for this service.

REDEEMING SHARES BY TELEPHONE

Redemptions in minimum amounts of $1,000 may be made by calling the
Fund provided the Fund has a properly completed authorization form.
These forms can be obtained from Federated Securities Corp. Proceeds
from redemption requests received before 5:00 p.m. (Eastern time) will
be wired the same day to the shareholder's account at a domestic
commercial bank which is a member of the Federal Reserve System, but
will not include that day's dividend. Proceeds from redeemed shares
purchased by check or through ACH will not be wired until that method
of payment has cleared. Proceeds from redemption requests on holidays
when wire transfers are restricted will be wired the following
business day. Questions about telephone redemptions on days when wire
transfers are restricted should be directed to your shareholder
services representative at the telephone number listed on your account
statement.

Telephone instructions may be recorded and if reasonable procedures
are not followed by the Fund, it may be liable for losses due to
unauthorized or fraudulent telephone instructions.

In the event of drastic economic or market changes, a shareholder may
experience difficulty in redeeming by telephone. If this occurs,
"Redeeming Shares by Mail" should be considered. If at any time the
Fund shall determine it necessary to terminate or modify the telephone
redemption privilege, shareholders would be promptly notified.

REDEEMING SHARES BY MAIL

Shares may be redeemed in any amount by mailing a written request to:
Federated Shareholder Services Company, P.O. Box 8600, Boston, MA
02266-8600. If share certificates have been issued, they should be
sent unendorsed with the written request by registered or certified
mail to the address noted above.

The written request should state: the Fund name and the class
designation; the account name as registered with the Fund; the account
number; and the number of shares to be redeemed or the dollar amount
requested. All owners of the account must sign the request exactly as
the shares are registered. Normally, a check for the proceeds is
mailed within one business day, but in no event more than seven days,
after the receipt of a proper written redemption request. Dividends
are paid up to and including the day that a redemption request is
processed.

Shareholders requesting a redemption of any amount to be sent to an
address other than that on record with the Fund or a redemption
payable other than to the shareholder of record must have their
signatures guaranteed by a commercial or savings bank, trust company
or savings association whose deposits are insured by an organization
which is administered by the Federal Deposit Insurance Corporation; a
member firm of a domestic stock exchange; or any other "eligible
guarantor institution," as defined in the Securities Exchange Act of
1934. The Fund does not accept signatures guaranteed by a notary
public.

SPECIAL REDEMPTION FEATURES

CHECK WRITING

Upon request, a checking account will be established to allow
shareholders to redeem their Fund shares. Shareholder accounts will
continue to receive the daily dividend declared on the shares to be
redeemed until the check is presented to UMB Bank, N.A., the bank
responsible for administering the check writing program, for payment.
However, checks should never be made payable or sent to UMB Bank, N.A.
or the Fund to redeem shares, and a check may not be written to close
an account.

DEBIT CARD

Upon request, a debit account will be established. This account allows
shareholders to redeem shares by using a debit card. A fee will be
charged to the account for this service.

SYSTEMATIC WITHDRAWAL PROGRAM

If a shareholder's account has a value of at least $25,000, other than
retirement accounts subject to required minimum distributions, a
systematic withdrawal program may be established whereby automatic
redemptions are made from the account and transferred electronically
to any commercial bank, savings bank, or credit union that is an ACH
member. Shareholders may apply for participation in this program
through their financial institutions or the Fund.

ACCOUNT AND SHARE INFORMATION

DIVIDENDS

Dividends are declared daily and paid monthly. Dividends are
automatically reinvested on payment dates in additional shares of the
Fund unless cash payments are requested by writing to the Fund. Shares
purchased by wire before 5:00 p.m. (Eastern time) begin earning
dividends that day. Shares purchased by check begin earning dividends
the day after the check is converted into federal funds.

CAPITAL GAINS

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 will distribute in cash or
additional shares any realized net long-term capital gains at least
once every 12 months.

CONFIRMATIONS AND ACCOUNT STATEMENTS

Shareholders will receive detailed confirmations of transactions
(except for systematic program transactions). In addition,
shareholders will receive periodic statements reporting all account
activity, including dividends paid. The Fund will not issue share
certificates.

ACCOUNTS WITH LOW BALANCES

Due to the high cost of maintaining accounts with low balances, the
Fund may redeem shares in any account, except accounts maintained by
retirement plans, and pay the proceeds to the shareholder if the
account balance falls below a required minimum value of $10,000 due to
shareholder redemptions. Before shares are redeemed to close an
account, the shareholder is notified in writing and allowed 30 days to
purchase additional shares to meet the minimum requirement.

VOTING RIGHTS

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

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

TAX INFORMATION

FEDERAL INCOME TAX

The Fund will pay no federal income tax because it expects to meet
requirements of the Internal Revenue Code applicable to regulated
investment companies and to receive the special tax treatment afforded
to such companies. The Fund will be treated as a single, separate
entity for federal income tax purposes so that income (including
capital gains) and losses realized by the Trust's other portfolios
will not be combined for tax purposes with those realized by the Fund.

Unless otherwise exempt, shareholders are required to pay federal
income tax on any dividends and other distributions received. This
applies whether dividends and distributions are received in cash or as
additional shares.

STATE AND LOCAL TAXES

In the opinion of Houston, Donnelly & Meck, counsel to the Trust, Fund
shares may be subject to personal property taxes imposed by counties,
municipalities, and school districts in Pennsylvania to the extent
that the portfolio securities in the Fund would be subject to such
taxes if owned directly by residents of those jurisdictions.

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

OTHER CLASSES OF SHARES

The Fund also offers other classes. Institutional Service Shares are
sold at net asset value primarily to retail and private banking
customers of financial institutions and are subject to a minimum
initial investment of $25,000.

All classes are subject to certain of the same expenses.

Institutional Service Shares are distributed with no 12b-1 Plan but
are subject to shareholder services fees.

Expense differences between classes may affect the performance of each
class.

To obtain more information and a prospectus for any other class,
investors may call 1-800-341-7400.

PERFORMANCE INFORMATION

From time to time, the Fund advertises its yield, effective yield and
total return. The performance figures will be calculated separately
for each class of shares.

Yield represents the annualized rate of income earned on an investment
over a seven-day period. It is the annualized dividends earned during
the period on an investment shown as a percentage of the investment.
The effective yield is calculated similarly to the yield, but when
annualized, the income earned by an investment is assumed to be
reinvested daily. The effective yield will be slightly higher than the
yield because of the compounding effect of this assumed reinvestment.

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

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

NOTES TO FINANCIAL STATEMENTS

AUTOMATED CASH MANAGEMENT TRUST

JULY 31, 1997

ORGANIZATION

Money Market Obligations Trust (the "Trust") is registered under the
Investment Company Act of 1940, as amended (the "Act") as an open-end,
management investment company. The Trust consists of six portfolios.
The financial statements included herein are only those of Automated
Cash Management Trust (the "Fund"). The financial statements of the
other portfolios are presented separately. The assets of each
portfolio are segregated and a shareholder's interest is limited to
the portfolio in which shares are held. The investment objective of
the Fund is stability of principal and current income consistent with
stability of principal.

The Fund offers two classes of shares: Institutional Service Shares and Cash
II Shares.

Effective September 27, 1996, the Trust added Cash II Shares.

SIGNIFICANT ACCOUNTING POLICIES

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

INVESTMENT VALUATIONS

The Fund uses the amortized cost method to value its portfolio
securities in accordance with Rule 2a-7 under the Act.

REPURCHASE AGREEMENTS

It is the policy of the Fund to require the custodian bank to take
possession, to have legally segregated in the Federal Reserve Book
Entry System, or to have segregated within the custodian bank's vault,
all securities held as collateral under repurchase agreement
transactions. Additionally, procedures have been established by the
Fund to monitor, on a daily basis, the market value of each repurchase
agreement's collateral to ensure that the value of collateral at least
equals the repurchase price to be paid under the repurchase agreement
transaction.

The Fund will only enter into repurchase agreements with banks and
other recognized financial institutions, such as broker/dealers, which
are deemed by the Fund's adviser to be creditworthy pursuant to the
guidelines and/or standards reviewed or established by the Board of
Trustees (the "Trustees"). Risks may arise from the potential
inability of counterparties to honor the terms of the repurchase
agreement. Accordingly, the Fund could receive less than the
repurchase price on the sale of collateral securities.

INVESTMENT INCOME, EXPENSES AND DISTRIBUTIONS

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

FEDERAL TAXES

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

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

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

RESTRICTED SECURITIES

Restricted securities are securities that may only be resold upon
registration under federal securities laws or in transactions exempt
from such registration. Many restricted securities may be resold in
the secondary market in transactions exempt from registration. In some
cases, the restricted securities may be resold without registration
upon exercise of a demand feature. Such restricted securities may be
determined to be liquid under criteria established by the Trustees.
The Fund will not incur any registration costs upon such resales.
Restricted securities are valued at amortized cost in accordance with
Rule 2a-7 under the Investment Company Act of 1940.

Additional information on each restricted security held at July 31,
1997 is as follows:

 Travelers Insurance Company, 5.841%             2/20/1997       44,000,000

USE OF ESTIMATES

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

OTHER

Investment transactions are accounted for on the trade date.

SHARES OF BENEFICIAL INTEREST

The Declaration of Trust permits the Trustees to issue an unlimited
number of full and fractional shares of beneficial interest (without
par value) for each class of shares. At July 31, 1997, capital paid-in
aggregated $2,104,248,881. Transactions in capital stock were as
follows:

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Shareholders and Board of Trustees of MONEY MARKET OBLIGATIONS
TRUST (Automated Cash Management Trust):

We have audited the accompanying statement of assets and liabilities
of Automated Cash Management Trust (an investment portfolio of Money
Market Obligations Trust, a Massachusetts business trust), including
the schedule of portfolio investments, as of July 31, 1997, the
related statement of operations for the year then ended, the statement
of changes in net assets for each of the two years in the period then
ended, and the financial highlights for each of the two years in the
period then ended, and for the period from May 1, 1995, to July 31,
1995. These financial statements and financial highlights are the
responsibility of the Trust's management. Our responsibility is to
express an opinion on these financial statements and financial
highlights based on our audits. The financial highlights for Automated
Cash Management Trust--Institutional Service Shares for the periods
ended April 30, 1987, through April 30, 1994, were audited by other
auditors whose report dated June 9, 1994, expressed an unqualified
opinion on those financial highlights.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements
and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts
and disclosures in the financial statements. Our procedures included
confirmation of securities owned as of July 31, 1997, by
correspondence with the custodian. An audit also includes assessing
the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements and financial highlights
referred to above present fairly, in all material respects, the
financial position of Automated Cash Management Trust (an investment
portfolio of Money Market Obligations Trust) as of July 31, 1997, and
the results of its operations for the year then ended, the changes in
its net assets for each of the two years in the period then ended, and
its financial highlights for each of the two years in the period then
ended and for the period from May 1, 1995, to July 31, 1995, in
conformity with generally accepted accounting principles.

GENERAL INFORMATION

The Trust was established as a Massachusetts business trust under a
Declaration of Trust dated October 3, 1988. The Declaration of Trust
permits the Trust to offer separate series of shares representing
interests in separate portfolios of securities. The shares in any one
portfolio may be offered in separate classes. With respect to this
Fund, as of the date of this prospectus, the Board of Trustees (the
"Trustees") has established two classes of shares known as
Institutional Service Shares and Cash II Shares. This prospectus
relates only to Institutional Service Shares of the Fund, which are
designed primarily for retail and private banking customers of
financial institutions as a convenient means of accumulating an
interest in a professionally managed portfolio investing in short-term
money market securities. A minimum initial investment of $25,000 over
a 90-day period is required except for retirement plans.

The Fund attempts to stabilize the value of a share at $1.00. Shares
are currently sold and redeemed at that price.

INVESTMENT INFORMATION

INVESTMENT OBJECTIVE

The investment objective of the Fund is stability of principal and
current income consistent with stability of principal. This investment
objective cannot be changed without shareholder approval. While there
is no assurance that the Fund will achieve its investment objective,
it endeavors to do so by complying with the diversification and other
requirements of Rule 2a-7 under the Investment Company Act of 1940
which regulates money market mutual funds and by following the
investment policies described in this prospectus.

INVESTMENT POLICIES

The Fund pursues its investment objective by investing in a portfolio
of money market instruments maturing in 13 months or less. The average
maturity of the money market instruments in the Fund's portfolio,
computed on a dollar-weighted basis, will be 90 days or less. Unless
indicated otherwise, the investment policies may not be changed by the
Trustees without shareholder approval.

ACCEPTABLE INVESTMENTS

The Fund invests in high quality money market instruments that are
either rated in the highest short-term rating category by one or more
nationally recognized statistical rating organizations ("NRSROs") or
are of comparable quality to securities having such ratings. Examples
of these instruments include, but are not limited to:

   * instruments of domestic and foreign banks and savings and loans
     (such as certificates of deposit, demand and time deposits,
     savings shares, and bankers' acceptances) if they have capital,
     surplus, and undivided profits of over $100,000,000, or if the
     principal amount of the instrument is insured by the Bank
     Insurance Fund ("BIF") which is administered by the Federal
     Deposit Insurance Corporation ("FDIC") or the Savings Association
     Insurance Fund ("SAIF") which is administered by the FDIC. These
     instruments may include Eurodollar Certificates of Deposit
     ("ECDs"), Yankee Certificates of Deposit ("Yankee CDs"), and
     Eurodollar Time Deposits ("ETDs");

   * commercial paper rated A-1 by Standard & Poor's Ratings Group,
     Prime-1 by Moody's Investors Service,Inc., or F-1 by Fitch
     Investors Service, and unrated but of comparable quality,
     including Canadian Commercial Paper ("CCPs") and Europaper.

   * marketable obligations issued or guaranteed by the U.S. government, its
     agencies, or instrumentalities; and

   * repurchase agreements.

The Fund invests only in instruments denominated and payable in U.S.
dollars.

REPURCHASE AGREEMENTS

Certain securities in which the Fund invests may be purchased pursuant
to repurchase agreements. Repurchase agreements are arrangements in
which banks, broker/dealers, and other recognized financial
institutions sell U. S. government securities or certificates of
deposit to the Fund and agree, at the time of sale, to repurchase them
at a mutually agreed upon time and price within one year from the date
of acquisition. The Fund or its custodian will take possession of the
securities subject to repurchase agreements and these securities will
be marked to market daily. To the extent that the original seller does
not repurchase the securities from the Fund, the Fund could receive
less than the repurchase price on any sale of such securities.

CREDIT ENHANCEMENT

Certain of the Fund's acceptable investments may be credit-enhanced by
a guaranty, letter of credit, or insurance. Any bankruptcy,
receivership, default or change in the credit quality of the party
providing the credit enhancement will adversely affect the quality and
marketability of the underlying security and could cause losses to the
Fund and affect its share price.

DEMAND FEATURES

As a matter of non-fundamental investment policy, the Fund may acquire
securities that are subject to puts and standby commitments ("demand
features") to purchase the securities at their principal amount
(usually with accrued interest) within a fixed period (usually seven
days) following a demand by the Fund. The demand feature may be issued
by the issuer of the underlying securities, a dealer in the
securities, or by another third party, and may not be transferred
separately from the underlying security. The Fund uses these
arrangements to provide the Fund with liquidity and not to protect
against changes in the market value of the underlying securities. The
bankruptcy, receivership, or default by the issuer of the demand
feature, or a default on the underlying security or other event that
terminates the demand feature before its exercise, will adversely
affect the liquidity of the underlying security. Demand features that
are exercisable even after a payment default on the underlying
security may be treated as a form of credit enhancement.

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

The Fund may purchase short-term U.S. government obligations on a
when-issued or delayed delivery basis. These transactions are
arrangements in which the Fund purchases securities with payment and
delivery scheduled for a future time. The Fund engages in when-issued
and delayed delivery transactions only for the purpose of acquiring
portfolio securities consistent with the Fund's investment objective
and policies, not for investment leverage. In when-issued and delayed
delivery transactions, the Fund relies on the seller to complete the
transaction. The seller's failure to deliver the securities may cause
the Fund to miss a price or yield considered to be advantageous.
Settlement dates may be a month or more after entering into these
transactions, and the market values of the securities purchased may
vary from the purchase prices.

As a matter of operating policy, the Fund may dispose of a commitment
prior to settlement if the adviser deems it appropriate to do so. In
addition, the Fund may enter into transactions to sell its purchase
commitments to third parties at current market values and
simultaneously acquire other commitments to purchase similar
securities at later dates. The Fund may realize short-term profits or
losses upon the sale of such commitments.

RESTRICTED AND ILLIQUID SECURITIES

The Fund may invest in restricted securities and as a matter of
fundamental investment policy which may not be changed without
shareholder approval, will limit such investments to 10% of its net
assets. This restriction is not applicable to commercial paper issued
under Section 4(2) of the Securities Act of 1933. Restricted
securities are any securities in which the Fund may invest pursuant to
its investment objective and policies but which are subject to
restrictions on resale under federal securities law. In addition, as a
matter of fundamental policy, the Fund will limit investments in
illiquid securities, including restricted securities determined not to
be liquid and repurchase agreements providing for settlement in more
than seven days after notice, to 10% of its net assets. Certain
instruments in which the Fund may invest, such as ETDs and repurchase
agreements with maturities of more than seven days, could be
considered illiquid.

INVESTMENT RISKS

ECDs, ETDs, Yankee CDs, Canadian Commercial Paper, and Europaper are
subject to different risks than domestic obligations of domestic banks
or corporations. Examples of these risks include international
economic and political developments, foreign governmental restrictions
that may adversely affect the payment of principal or interest,
foreign withholding or other taxes on interest income, difficulties in
obtaining or enforcing a judgment against the issuing entity, and the
possible impact of interruptions in the flow of international currency
transactions. Risks may also exist for ECDs, ETDs, and Yankee CDs
because the banks issuing these instruments, or their domestic or
foreign branches, are not necessarily subject to the same regulatory
requirements that apply to domestic banks, such as reserve
requirements, loan limitations, examinations, accounting, auditing,
recordkeeping, and the public availability of information. These
factors will be carefully considered by the Fund's adviser in
selecting investments for the Fund.

INVESTMENT LIMITATIONS

The Fund will not borrow money directly or through reverse repurchase
agreements (arrangements in which the Fund sells a money market
instrument for a percentage of its cash value with an agreement to buy
it back on a set date) or pledge securities except, under certain
circumstances, the Fund may borrow up to one-third of the value of its
total assets and pledge up to 10% of the value of its total assets to
secure such borrowings. These investment limitations cannot be changed
without shareholder approval.

FUND INFORMATION

MANAGEMENT OF THE FUND

BOARD OF TRUSTEES

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

INVESTMENT ADVISER

Investment decisions for the Fund are made by Federated Management,
the Fund's investment adviser, subject to direction by the Trustees.
The adviser continually conducts investment research and supervision
for the Fund and is responsible for the purchase and sale of portfolio
instruments.

Advisory Fees

The adviser receives an annual investment advisory fee equal to 0.50%
of the Fund's average daily net assets. The adviser may voluntarily
choose to waive a portion of its fee or reimburse other expenses of
the Fund, but reserves the right to terminate such waiver or
reimbursement at any time at its sole discretion.

Adviser's Background

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

Federated Management and other subsidiaries of Federated Investors
serve as investment advisers to a number of investment companies and
private accounts. Certain other subsidiaries also provide
administrative services to a number of investment companies. With over
$110 billion invested across over 300 funds under management and/or
administration by its subsidiaries, as of December 31, 1996, Federated
Investors is one of the largest mutual fund investment managers in the
United States. With more than 2,000 employees, Federated continues to
be led by the management who founded the company in 1955. Federated
funds are presently at work in and through 4,500 financial
institutions nationwide.

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

DISTRIBUTION OF INSTITUTIONAL SERVICE SHARES

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

Federated Investors.

SHAREHOLDER SERVICES

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

SUPPLEMENTAL PAYMENTS TO FINANCIAL INSTITUTIONS

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

ADMINISTRATION OF THE FUND

ADMINISTRATIVE SERVICES

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

 MAXIMUM         AVERAGE AGGREGATE
   FEE            DAILY NET ASSETS

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

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

NET ASSET VALUE

The Fund attempts to stabilize the net asset value of shares at $1.00
by valuing the portfolio securities using the amortized cost method.
The net asset value per share is determined by subtracting liabilities
attributable to Institutional Service Shares from the value of Fund
assets attributable to Institutional Service Shares, and dividing the
remainder by the number of Institutional Service Shares outstanding.
The Fund cannot guarantee that its net asset value will always remain
at $1.00 per share.

The net asset value is determined at 5:00 p.m. (Eastern time), Monday
through Friday, except on New Year's Day, Martin Luther King Day,
Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor
Day, Thanksgiving Day, and Christmas Day.

HOW TO PURCHASE SHARES

Shares are sold at their net asset value, without a sales charge, next
determined after an order is received, on days which the New York
Stock Exchange is open for business. Shares may be purchased as
described below, either through a financial institution (such as a
bank or broker/dealer) or by wire or by check directly from the Fund,
with a minimum initial investment of $25,000 or more over a 90-day
period. Financial institutions may impose different minimum investment
requirements on their customers.

In connection with any sale, Federated Securities Corp. may from time
to time offer certain items of nominal value to any shareholder or
investor. The Fund reserves the right to reject any purchase request.
An account must be established at a financial institution or by
completing, signing, and returning the new account form available from
the Fund before shares can be purchased.

PURCHASING SHARES THROUGH A FINANCIAL INSTITUTION

Investors may purchase shares through a financial institution which
has a sales agreement with the distributor. Orders are considered
received when the Fund receives payment by wire or converts payment by
check from the financial institution into federal funds. It is the
financial institution's responsibility to transmit orders promptly.
Financial institutions may charge additional fees for their services.

PURCHASING SHARES BY WIRE

Shares may be purchased by wire by calling the Fund before 5:00 p.m.
Eastern time to place an order. The order is considered received
immediately. Payment by federal funds must be received before 5:00
p.m. Eastern time in order to begin earning dividends that same day.
Federal funds should be wired as follows: Federated Shareholder
Services Company, c/o State Street Bank and Trust Company, Boston, MA;
Attention: EDGEWIRE; For Credit to: Automated Cash Management
Trust--Institutional Service Shares; Fund Number (this number can be
found on the account statement or by contacting the Fund); Group
Number or Order Number; Nominee or Institution Name; and ABA Number
011000028. Shares cannot be purchased by wire on holidays when wire
transfers are restricted. Questions on wire purchases should be
directed to your shareholder services representative at the telephone
number listed on your account statement.

PURCHASING SHARES BY CHECK

Shares may be purchased by sending a check to Federated Shareholder
Services Company, P.O. Box 8600, Boston, MA 02266-8600. The check
should be made payable to Automated Cash Management
Trust--Institutional Service Shares. Please include an account number
on the check. 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.

INVEST-BY-PHONE

Once an account has been opened, a shareholder may use invest-by-phone
for investments if an authorization form has been filed with Federated
Shareholder Services Company, the transfer agent for shares of the
Fund. Approximately two weeks after sending the form to Federated
Shareholder Services Company, the shareholder may call Federated
Shareholder Services Company to purchase shares. Federated Shareholder
Services Company will send a request for monies to the shareholder's
commercial bank, savings bank, or credit union ("bank") via the
Automated Clearing House. The shareholder's bank, which must be an
Automated Clearing House member, will then forward the monies to
Federated Shareholder Services Company. The purchase is normally
entered the next business day after the initial phone request. For
further information and an application, call the Fund.

BY DIRECT DEPOSIT

Shareholders of the Fund may have their Social Security, Railroad
Retirement, VA Compensation or Pension, Civil Service Retirement, and
certain other retirement payments invested directly into their Fund
account. Shareholders must complete an application and file it with
Federated Shareholder Services Company prior to use of this program.
Allow 60 to 90 days for the application to be processed.

AUTOMATIC INVESTMENTS

Investors may establish accounts with their financial institutions to
have cash accumulations automatically invested in the Fund. The
investments may be made on predetermined dates or when the investor's
account reaches a certain level. Participating financial institutions
are responsible for prompt transmission of orders relating to the
program, and they may charge for their services. Investors should read
this prospectus along with the financial institution's agreement or
literature describing these services and fees.

SUBACCOUNTING SERVICES

Financial institutions are encouraged to open single master accounts.
A subaccounting system is available through the transfer agent to
minimize internal recordkeeping requirements. The transfer agent
charges a fee based on the level of subaccounting services rendered.
Financial institutions 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 provided which may be related
to the ownership of Fund shares. This prospectus should, therefore, be
read together with any agreement between the customer and the
financial institution with regard to the services provided, the fees
charged for those services, and any restrictions and limitations
imposed.

SPECIAL PURCHASE FEATURES

SYSTEMATIC INVESTMENT PROGRAM

A minimum of $100 can be automatically withdrawn periodically from the
shareholder's checking account at an Automated Clearing House ("ACH")
member and invested in Fund shares. Shareholders should contact their
financial institution or the Fund to participate in this program.

HOW TO REDEEM SHARES

Shares are redeemed at their net asset value next determined after
Federated Shareholder Services Company receives the redemption
request. Redemptions will be made on days on which the Fund computes
its net asset value. Redemption requests must be received in proper
form and can be made as described below.

REDEEMING SHARES THROUGH A FINANCIAL INSTITUTION

Shares may be redeemed by contacting the shareholder's financial
institution. Shares will be redeemed at the net asset value next
determined after Federated Shareholder Services Company receives the
redemption request. According to the shareholder's instructions,
redemption proceeds can be sent to the financial institution or to the
shareholder by check or by wire. The financial institution is
responsible for promptly submitting redemption requests and providing
proper written redemption instructions. Customary fees and commissions
may be charged by the financial institution for this service.

REDEEMING SHARES BY TELEPHONE

Redemptions in any amount may be made by calling the Fund provided the
Fund has a properly completed authorization form. These forms can be
obtained from Federated Securities Corp. Proceeds from redemption
requests before 5:00 p.m. (Eastern time) will be wired the same day to
the shareholder's account at a domestic commercial bank which is a
member of the Federal Reserve System, but will not include that day's
dividend. Proceeds from redeemed shares purchased by check or through
ACH will not be wired until that method of payment has cleared.
Proceeds from redemption requests on holidays when wire transfers are
restricted will be wired the following business day. Questions about
telephone redemptions on days when wire transfers are restricted
should be directed to your shareholder services representative at the
telephone number listed on your account statement.

Telephone instructions may be recorded and if reasonable procedures
are not followed by the Fund, it may be liable for losses due to
unauthorized or fraudulent telephone instructions.

In the event of drastic economic or market changes, a shareholder may
experience difficulty in redeeming by telephone. If this occurs,
"Redeeming Shares by Mail" should be considered. If at any time the
Fund shall determine it necessary to terminate or modify the telephone
redemption privilege, shareholders would be promptly notified.

REDEEMING SHARES BY MAIL

Shares may be redeemed in any amount by mailing a written request to:
Federated Shareholder Services Company, P.O. Box 8600, Boston, MA
02266-8600. If share certificates have been issued, they should be
sent unendorsed with the written request by registered or certified
mail to the address noted above.

The written request should state: the Fund name and the class
designation; the account name as registered with the Fund; the account
number; and the number of shares to be redeemed or the dollar amount
requested. All owners of the account must sign the request exactly as
the shares are registered. Normally, a check for the proceeds is
mailed within one business day, but in no event more than seven days,
after the receipt of a proper written redemption request. Dividends
are paid up to and including the day that a redemption request is
processed.

Shareholders requesting a redemption of any amount to be sent to an
address other than that on record with the Fund or a redemption
payable other than to the shareholder of record must have their
signatures guaranteed by a commercial or savings bank, trust company
or savings association whose deposits are insured by an organization
which is administered by the Federal Deposit Insurance Corporation; a
member firm of a domestic stock exchange; or any other "eligible
guarantor institution," as defined in the Securities Exchange Act of
1934. The Fund does not accept signatures guaranteed by a notary
public.

SPECIAL REDEMPTION FEATURES

CHECK WRITING

Upon request, a checking account will be established to allow
shareholders to redeem their Fund shares. Shareholder accounts will
continue to receive the daily dividend declared on the shares to be
redeemed until the check is presented to UMB Bank, N.A., the bank
responsible for administering the check writing program, for payment.
However, checks should never be made payable or sent to UMB Bank, N.A.
or the Fund to redeem shares, and a check may not be written to close
an account.

DEBIT CARD

Upon request, a debit account will be established. This account allows
shareholders to redeem shares by using a debit card. A fee will be
charged to the account for this service.

SYSTEMATIC WITHDRAWAL PROGRAM

If a shareholder's account has a value of at least $25,000, other than
retirement accounts subject to required minimum distributions, a
systematic withdrawal program may be established whereby automatic
redemptions are made from the account and transferred electronically
to any commercial bank, savings bank, or credit union that is an ACH
member. Shareholders may apply for participation in this program
through their financial institutions or the Fund.

ACCOUNT AND SHARE INFORMATION

DIVIDENDS

Dividends are declared daily and paid monthly. Dividends are
automatically reinvested on payment dates in additional shares of the
Fund unless cash payments are requested by writing to the Fund. Shares
purchased by wire before 5:00 p.m. (Eastern time) begin earning
dividends that day. Shares purchased by check begin earning dividends
the day after the check is converted into federal funds.

CAPITAL GAINS

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 will distribute in cash or
additional shares any realized net long-term capital gains at least
once every 12 months.

CONFIRMATIONS AND ACCOUNT STATEMENTS

Shareholders will receive detailed confirmations of transactions
(except for systematic program transactions). In addition,
shareholders will receive periodic statements reporting all account
activity, including dividends paid. The Fund will not issue share
certificates.

ACCOUNTS WITH LOW BALANCES

Due to the high cost of maintaining accounts with low balances, the
Fund may redeem shares in any account, except accounts maintained by
retirement plans, and pay the proceeds to the shareholder if the
account balance falls below a required minimum value of $25,000 due to
shareholder redemptions. Before shares are redeemed to close an
account, the shareholder is notified in writing and allowed 30 days to
purchase additional shares to meet the minimum requirement.

VOTING RIGHTS

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

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

TAX INFORMATION

FEDERAL INCOME TAX

The Fund will pay no federal income tax because it expects to meet
requirements of the Internal Revenue Code applicable to regulated
investment companies and to receive the special tax treatment afforded
to such companies. The Fund will be treated as a single, separate
entity for federal income tax purposes so that income (including
capital gains) and losses realized by the Trust's other portfolios
will not be combined for tax purposes with those realized by the Fund.

Unless otherwise exempt, shareholders are required to pay federal
income tax on any dividends and other distributions received. This
applies whether dividends and distributions are received in cash or as
additional shares.

STATE AND LOCAL TAXES

In the opinion of Houston, Donnelly & Meck, counsel to the Trust, Fund
shares may be subject to personal property taxes imposed by counties,
municipalities, and school districts in Pennsylvania to the extent
that the portfolio securities in the Fund would be subject to such
taxes if owned directly by residents of those jurisdictions.

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

OTHER CLASSES OF SHARES

The Fund also offers other classes. Cash II Shares are sold at net
asset value primarily to retail customers of financial institutions
and are subject to a minimum initial investment of $25,000.

All classes are subject to certain of the same expenses.

Cash II Shares are distributed under a 12b-1 Plan adopted by the Fund
and also are subject to shareholder services fees.

Expense differences between classes may affect the performance of each
class.

To obtain more information and a prospectus for any other class,
investors may call 1-800-341-7400.

PERFORMANCE INFORMATION

From time to time, the Fund advertises its yield, effective yield and
total return. The performance figures will be calculated separately
for each class of shares.

Yield represents the annualized rate of income earned on an investment
over a seven-day period. It is the annualized dividends earned during
the period on an investment shown as a percentage of the investment.
The effective yield is calculated similarly to the yield, but when
annualized, the income earned by an investment is assumed to be
reinvested daily. The effective yield will be slightly higher than the
yield because of the compounding effect of this assumed reinvestment.

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

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

NOTES TO FINANCIAL STATEMENTS

AUTOMATED CASH MANAGEMENT TRUST

JULY 31, 1997

ORGANIZATION

Money Market Obligations Trust (the "Trust") is registered under the
Investment Company Act of 1940, as amended (the "Act") as an open-end,
management investment company. The Trust consists of six portfolios.
The financial statements included herein are only those of Automated
Cash Management Trust (the "Fund"). The financial statements of the
other portfolios are presented separately. The assets of each
portfolio are segregated and a shareholder's interest is limited to
the portfolio in which shares are held. The investment objective of
the Fund is stability of principal and current income consistent with
stability of principal.

The Fund offers two classes of shares: Institutional Service Shares and Cash
II Shares.

Effective September 27, 1996, the Trust added Cash II Shares.

SIGNIFICANT ACCOUNTING POLICIES

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

INVESTMENT VALUATIONS

The Fund uses the amortized cost method to value its portfolio
securities in accordance with Rule 2a-7 under the Act.

REPURCHASE AGREEMENTS

It is the policy of the Fund to require the custodian bank to take
possession, to have legally segregated in the Federal Reserve Book
Entry System, or to have segregated within the custodian bank's vault,
all securities held as collateral under repurchase agreement
transactions. Additionally, procedures have been established by the
Fund to monitor, on a daily basis, the market value of each repurchase
agreement's collateral to ensure that the value of collateral at least
equals the repurchase price to be paid under the repurchase agreement
transaction.

The Fund will only enter into repurchase agreements with banks and
other recognized financial institutions, such as broker/dealers, which
are deemed by the Fund's adviser to be creditworthy pursuant to the
guidelines and/or standards reviewed or established by the Board of
Trustees (the "Trustees"). Risks may arise from the potential
inability of counterparties to honor the terms of the repurchase
agreement. Accordingly, the Fund could receive less than the
repurchase price on the sale of collateral securities.

INVESTMENT INCOME, EXPENSES AND DISTRIBUTIONS

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

FEDERAL TAXES

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

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

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

RESTRICTED SECURITIES

Restricted securities are securities that may only be resold upon
registration under federal securities laws or in transactions exempt
from such registration. Many restricted securities may be resold in
the secondary market in transactions exempt from registration. In some
cases, the restricted securities may be resold without registration
upon exercise of a demand feature. Such restricted securities may be
determined to be liquid under criteria established by the Trustees.
The Fund will not incur any registration costs upon such resales.
Restricted securities are valued at amortized cost in accordance with
Rule 2a-7 under the Investment Company Act of 1940.

Additional information on each restricted security held at July 31,
1997 is as follows:

USE OF ESTIMATES

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

OTHER

Investment transactions are accounted for on the trade date.

number of full and fractional shares of beneficial interest (without
par value) for each class of shares. At July 31, 1997, capital paid-in
aggregated $2,104,248,881. Transactions in capital stock were as

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Shareholders and Board of Trustees of MONEY MARKET OBLIGATIONS
TRUST (Automated Cash Management Trust):

We have audited the accompanying statement of assets and liabilities
of Automated Cash Management Trust (an investment portfolio of Money
Market Obligations Trust, a Massachusetts business trust), including
the schedules of portfolio investments, as of July 31, 1997, the
related statement of operations for the year then ended, the statement
of changes in net assets for each of the two years in the period then
ended, and the financial highlights for each of the two years in the
period then ended, and for the period from May 1, 1995, to July 31,
1995. These financial statements and financial highlights are the
responsibility of the Trust's management. Our responsibility is to
express an opinion on these financial statements and financial
highlights based on our audits. The financial highlights for Automated
Cash Management Trust--Institutional Service Shares for the periods
ended April 30, 1987, through April 30, 1994, were audited by other
auditors whose report dated June 9, 1994, expressed an unqualified
opinion on those financial highlights.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements
and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts
and disclosures in the financial statements. Our procedures included
confirmation of securities owned as of July 31, 1997, by
correspondence with the custodian. An audit also includes assessing
the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis
for our opinion.

In our opinion, the financial statements and financial highlights

FUND HISTORY

Effective July 30, 1994, Automated Cash Management Trust was
reorganized into an investment portfolio of Money Market Obligations
Trust. The Trust is registered under the Investment Company Act of
1940 as an open-end, management investment company. The Trust consists
of six diversified portfolios.

INVESTMENT POLICIES

Unless indicated otherwise, the policies described below may not be
changed by the Board of Trustees (the "Trustees") without shareholder
approval. Shareholders will be notified before any material change in
these policies becomes effective.

ACCEPTABLE INVESTMENTS

When determining whether a security presents minimal credit risks, the
investment adviser will consider the creditworthiness of: the issuer
of the security; the issuer of any demand feature applicable to the
security; or any guarantor of either the security or any demand
feature.

U.S. GOVERNMENT SECURITIES

The types of U.S. government securities in which the Fund may invest
generally include direct obligations of the U.S. Treasury (such as U.S.
Treasury bills, notes, and bonds) and obligations issued or guaranteed by
U.S. government agencies or instrumentalities. These securities are backed
by:

   * the full faith and credit of the U.S. Treasury;
   * the issuer's right to borrow from the U.S. Treasury;

   * the discretionary authority of the U.S. government to purchase certain
     obligations of agencies or instrumentalities; or

   * the credit of the agency or instrumentality issuing the obligations.

BANK INSTRUMENTS

The instruments of banks and savings associations whose deposits are
insured by the Bank Insurance Fund ("BIF") or the Savings Association
Insurance Fund ("SAIF"), such as certificates of deposit, demand and
time deposits, savings shares, and bankers' acceptances, are not
necessarily guaranteed by those organizations. In addition to domestic
bank instruments, the Fund may invest in: Eurodollar Certificates of
Deposit issued by foreign branches of U.S. or foreign banks;
Eurodollar Time Deposits, which are U.S. dollar-denominated deposits
in foreign branches of U.S. or foreign banks; Canadian Time Deposits,
which are U.S. dollar-denominated deposits issued by branches of major
Canadian banks located in the United States; and Yankee Certificates
of Deposit, which are U.S. dollar-denominated certificates of deposit
issued by U.S. branches of foreign banks and held in the United
States.

RATINGS

An NRSRO's highest rating category is determined without regard for
sub-categories and gradations. For example, securities rated A-1 or A-1+ by
Standard & Poor's Ratings Group ("S&P"), Prime-1 by Moody's Investors
Service, Inc. ("Moody's"), or F-1 (+ or -) by Fitch Investors Service, Inc.
("Fitch") are all considered rated in the highest short-term rating
category. The Fund will follow applicable regulations in determining whether
a security rated by more than one NRSRO can be treated as being in the
highest short-term rating category; currently, such securities must be rated
by two NRSROs in their highest rating category. See "Regulatory Compliance."

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

These transactions are made to secure what is considered to be an
advantageous price or yield for the Fund. No fees or other expenses,
other than normal transaction costs, are incurred. However, liquid
assets of the Fund in a dollar amount sufficient to make payment for
the securities to be purchased are: segregated on the Fund's records
at the trade date; marked to market daily; and maintained until the
transaction is settled.

REPURCHASE AGREEMENTS

The Fund or its custodian will take possession of the securities
subject to repurchase agreements, and these securities will be marked
to market daily. In the event that a defaulting seller filed for
bankruptcy or became insolvent, disposition of such securities by the
Fund might be delayed pending court action. The Fund believes that
under the regular procedures normally in effect for custody of the
Fund's portfolio securities subject to repurchase agreements, a court
of competent jurisdiction would rule in favor of the Fund and allow
retention or disposition of such securities. The Fund will only enter
into repurchase agreements with banks and other recognized financial
institutions, such as broker/dealers, which are deemed by the Fund's
adviser to be creditworthy pursuant to guidelines established by the
Trustees.

RESTRICTED AND ILLIQUID SECURITIES

The Fund may invest in commercial paper issued in reliance on the
exemption from registration afforded by Section 4(2) of the Securities
Act of 1933. Section 4(2) commercial paper is restricted as to
disposition under federal securities law, and generally is sold to
institutional investors, such as the Fund, who agree that they are
purchasing the paper for investment purposes and not with a view to
public distribution. Any resale by the purchaser must be in an exempt
transaction. Section 4(2) commercial paper normally is resold to other
institutional investors like the Fund through or with the assistance
of the issuer or investment dealers who make a market in Section 4(2)
commercial paper, thus providing liquidity. The Fund believes that
Section 4(2) commercial paper and possibly certain other restricted
securities which meet the criteria for liquidity established by the
Trustees of the Fund are quite liquid. The Fund intends, therefore, to
treat the restricted securities which meet the criteria for liquidity
established by the Trustees, including Section 4(2) commercial paper,
as determined by the Fund's investment adviser, as liquid and not
subject to the investment limitation applicable to illiquid
securities. In addition, because Section 4(2) commercial paper is
liquid, the Fund intends to not subject such paper to the limitation
applicable to restricted securities.

REVERSE REPURCHASE AGREEMENTS

The Fund may also enter into reverse repurchase agreements. These
transactions are similar to borrowing cash. In a reverse repurchase
agreement, the Fund transfers possession of a portfolio instrument in
return for a percentage of the instrument's market value in cash and
agrees that on a stipulated date in the future the Fund will
repurchase the portfolio instrument by remitting the original
consideration plus interest at an agreed-upon rate. The use of reverse
repurchase agreements may enable the Fund to avoid selling portfolio
instruments at a time when a sale may be deemed to be disadvantageous,
but does not ensure this result. However, liquid assets of the Fund,
in a dollar amount sufficient to make payment for the securities to be
purchased, are: segregated on the Fund's records at the trade date;
marked to market daily; and maintained until the transaction is
settled.

CREDIT ENHANCEMENT

The Fund typically evaluates the credit quality and ratings of
credit-enhanced securities based upon the financial condition and
ratings of the party providing the credit enhancement (the "credit
enhancer"), rather than the issuer. However, credit-enhanced
securities will not be treated as having been issued by the credit
enhancer for diversification purposes unless the Fund has invested
more than 10% of its assets in securities issued, guaranteed or
otherwise credit enhanced by the credit enhancer, in which case the
securities will be treated as having been issued by both the issuer
and the credit enhancer. The Fund may have more than 25% of its total
assets invested in securities credit enhanced by banks.

INVESTMENT LIMITATIONS

SELLING SHORT AND BUYING ON MARGIN

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

ISSUING SENIOR SECURITIES AND BORROWING MONEY

The Fund will not issue senior securities except that the Fund may
borrow money directly or through reverse repurchase agreements in
amounts up to one-third of the value of its total assets, including
the amounts borrowed.

The Fund will not borrow money or engage in reverse repurchase
agreements for investment leverage, but rather as a temporary,
extraordinary, or emergency measure or to facilitate management of the
portfolio by enabling the Fund to meet redemption requests when the
liquidation of portfolio securities is deemed to be inconvenient or
disadvantageous. The Fund will not purchase any securities while
borrowings in excess of 5% of the value of its total assets are
outstanding.

PLEDGING ASSETS

The Fund will not mortgage, pledge, or hypothecate any assets except
as necessary to secure permitted borrowings. In those cases, it may
mortgage, pledge or hypothecate assets having a market value not
exceeding the lesser of the dollar amounts borrowed or 10% of the
value of total assets at the time of the borrowing.

LENDING CASH OR SECURITIES

The Fund will not lend any of its assets, except that it may purchase
or hold money market instruments, including repurchase agreements,
permitted by its investment objective and policies.

INVESTING IN COMMODITIES, MINERALS, OR REAL ESTATE

The Fund will not invest in commodities, commodity contracts, oil,
gas, or other mineral programs or real estate, except that it may
purchase money market instruments issued by companies that invest in
or sponsor interests.

UNDERWRITING

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

CONCENTRATION OF INVESTMENTS

The Fund will not purchase money market instruments if, as a result of
such purchase, more than 25% of the value of its total assets would be
invested in one industry. However, investing in bank instruments (such
as time and demand deposits and certificates of deposit), U.S.
government obligations, or instruments secured by these money market
instruments, such as repurchase agreements, shall not be considered
investments in any one industry.

ACQUIRING SECURITIES

The Fund will not acquire the voting securities of any issuer. It will
not invest in securities issued by any other investment company,
except as part of a merger, consolidation, or other acquisition. It
will not invest in securities of a company for the purpose of
exercising control or management.

DIVERSIFICATION OF INVESTMENTS

The Fund will not purchase securities issued by any one issuer having
a value of more than 5% of the value of its total assets except cash
or cash items, repurchase agreements, and U.S. government obligations.

INVESTING IN RESTRICTED SECURITIES

The Fund will not invest in securities which are subject to
restrictions on resale under federal securities laws except that the
Fund may invest up to 10% of its net assets in high-quality securities
subject to such restrictions. This limitation is not applicable to
commercial paper issued under Section 4(2) of the Securities Act of
1933.

INVESTING IN NEW ISSUERS

The Fund will not invest more than 5% of the value of its total assets
in money market instruments of unseasoned issuers, including their
predecessors, that have been in operation for less than three years.

INVESTING IN OPTIONS

The Fund will not invest in puts, calls, straddles, spreads, or any
combination of them.

INVESTING IN ISSUERS WHOSE SECURITIES ARE OWNED BY OFFICERS AND TRUSTEES

The Fund will not purchase or retain the securities of any issuer if
the officers and Trustees of the Trust or its investment adviser,
owning individually more than 0.50 of 1% of the issuer's securities,
together beneficially own more than 5% of the issuer's securities.

The above limitations cannot be changed without shareholder approval.

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.

The Fund did not borrow money or pledge securities in excess of 5% of
the value of its net assets during the last fiscal year and has no
present intent to do so during the coming fiscal year.

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, which regulates money market mutual funds.
For example, with limited exceptions, Rule 2a-7 prohibits the
investment of more than 5% of the Fund's total assets in the
securities of any one issuer, although the Fund's investment
limitation only requires such 5% diversification with respect to 75%
of its assets. The Fund will invest more than 5% of its assets in any
one issuer only under the circumstances permitted by Rule 2a-7. The
Fund also will determine the effective maturity of its investments, as
well as its ability to consider a security as having received the
requisite short-term ratings by NRSROs, according to Rule 2a-7. The
Fund may change these operational policies to reflect changes in the
laws and regulations without the approval of its shareholders.

TRUSTEE LIABILITY

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

INVESTMENT ADVISORY SERVICES

INVESTMENT ADVISER

The Fund's investment adviser is Federated Management. It is a subsidiary of
Federated Investors. All the voting securities of Federated Investors are
owned by a trust, the trustees of which are John F. Donahue, his wife and
his son, J. Christopher Donahue.

The adviser shall not be liable to the Automated Cash Management
Trust, the Fund, or any shareholder of the Fund 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
Automated Cash Management Trust.

ADVISORY FEES

For its advisory services, Federated Management receives an annual
investment advisory fee as described in the prospectus. For the fiscal
years ended July 31, 1997 and 1996, the adviser earned $9,287,875 and
$6,308,051, respectively, of which $5,899,812 and $3,773,437,
respectively, were waived. For the fiscal year ended April 30, 1995,
and for the period from April 30, 1995 to July 31, 1995, the adviser
earned $5,173,695 and $1,348,977, respectively, of which $3,374,156
and $1,049,124 were waived, respectively.

BROKERAGE TRANSACTIONS

When selecting brokers and dealers to handle the purchase and sale of
portfolio instruments, the adviser looks for prompt execution of the
order at a favorable price. In working with dealers, the adviser will
generally use those who are recognized dealers in specific portfolio
instruments, except when a better price and execution of the order can
be obtained elsewhere. The adviser makes decisions on portfolio
transactions and selects brokers and dealers subject to guidelines
established by the Trustees. The adviser may select brokers and
dealers who offer brokerage and research services. These services may
be furnished directly to the Fund or to the adviser and may include:
advice as to the advisability of investing in securities; security
analysis and reports; economic studies; industry studies; receipt of
quotations for portfolio evaluations; and similar services. Research
services provided by brokers and dealers may be used by the adviser or
its affiliates in advising the Fund and other accounts. To the extent
that receipt of these services may supplant services for which the
adviser or its affiliates might otherwise have paid, it would tend to
reduce their expenses. The adviser and its affiliates exercise
reasonable business judgment in selecting brokers who offer brokerage
and research services to execute securities transactions. They
determine in good faith that commissions charged by such persons are
reasonable in relationship to the value of the brokerage and research
services provided. During the fiscal years ended July 31, 1997 and
1996, the fiscal year ended April 30, 1995, and the period from April
30, 1995, to July 31, 1995, the Fund paid no brokerage commissions.

Although investment decisions for the Fund are made independently from
those of the other accounts managed by the adviser, investments of the
type the Fund may make may also be made by those other accounts. When
the Fund and one or more other accounts managed by the adviser are
prepared to invest in, or desire to dispose of, the same security,
available investments or opportunities for sales will be allocated in
a manner believed by the adviser to be equitable to each. In some
cases, this procedure may adversely affect the price paid or received
by the Fund or the size of the position obtained or disposed of by the
Fund. In other cases, however, it is believed that coordination and
the ability to participate in volume transactions will be to the
benefit of the Fund.

OTHER SERVICES

FUND ADMINISTRATION

Federated Services Company, a subsidiary of Federated Investors,
provides administrative personnel and services to the Fund for a fee
as described in the prospectus. From March 1, 1994, to March 1, 1996,
Federated Administrative Services, a subsidiary of Federated
Investors, served as the Fund's Administrator. For purposes of this
Statement of Additional Information, Federated Services Company and
Federated Administrative Services may hereinafter collectively be
referred to as the "Administrators." For the fiscal years ended July
31, 1997 and 1996, the Administrators earned $1,402,868 and $954,191,
respectively. For the fiscal year ended April 30, 1995, and for the
period from April 30, 1995, to July 31, 1995, the Administrators
earned $783,297 and $204,235, respectively.

CUSTODIAN AND PORTFOLIO ACCOUNTANT

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

TRANSFER AGENT

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

INDEPENDENT PUBLIC ACCOUNTANTS

The independent public accountants for the Fund are Arthur Andersen
LLP, Pittsburgh, Pennsylvania.

DISTRIBUTION PLAN AND SHAREHOLDER SERVICES

With respect to Cash II Shares, the Fund has adopted a Plan pursuant
to Rule 12b-1 which was promulgated by the Securities and Exchange
Commission pursuant to the Investment Company Act of 1940. Both Cash
II Shares and Institutional Service Shares operate subject to
shareholder servicing agreements.

These arrangements permit the payment of fees to financial
institutions, the distributor, and Federated Shareholder Services, to
stimulate distribution activities and to cause services to be provided
to shareholders by a representative who has knowledge of the
shareholder's particular circumstances and goals. These activities and
services may include but are not limited to marketing efforts;
providing office space, equipment, telephone facilities, and various
clerical, supervisory, computer, and other personnel as necessary or
beneficial to establish and maintain shareholder accounts and records;
processing purchase and redemption transactions and automatic
investments of client account cash balances; answering routine client
inquiries; and assisting clients in changing dividend options, account
designations, and addresses.

By adopting the Plan, the Trustees expect that the Fund will be able
to achieve a more predictable flow of cash for investment purposes and
to meet redemptions. This will facilitate more efficient portfolio
management and assist the Fund in seeking to achieve its investment
objectives. By identifying potential investors whose needs are served
by the Fund's objectives, and properly servicing these accounts, the
Fund may be able to curb sharp fluctuations in rates of redemptions
and sales.

Other benefits, which may be realized under either arrangement, may
include: (1) providing personal services to shareholders; (2)
investing shareholder assets with a minimum of delay and
administrative detail; (3) enhancing shareholder recordkeeping
systems; and (4) responding promptly to shareholders' requests and
inquiries concerning their accounts.

For the fiscal year ended July 31, 1997, payments for Cash II Shares
in the amount of $1,245,101 were made pursuant to the Plan, $806,956
of which was paid to financial institutions. In addition, for the
fiscal year ended July 31, 1997, the Fund paid shareholder service
fees on behalf of Institutional Service Shares and Cash II Shares in
the amounts of $3,398,836 and $1,245,101, respectively, $95,168 and $0
of which were waived, respectively.

DETERMINING NET ASSET VALUE

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 Rule
2a-7 (the "Rule") promulgated by the Securities and Exchange
Commission under the Investment Company Act of 1940. 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.

REDEMPTION IN KIND

The Fund is obligated to redeem shares solely in cash up to $250,000
or 1% of the Fund's net asset value, whichever is less, for any one
shareholder within a 90-day period. Any redemption beyond this amount
will also be in cash unless the Trustees determine that further
payments should be in kind. In such cases, the Fund will pay all or a
portion of the remainder of the redemption in portfolio instruments
valued in the same way as the Fund determines net asset value. The
portfolio instruments will be selected in a manner that the Trustees
deem fair and equitable. Redemption in kind is not as liquid as a cash
redemption. If redemption is made in kind, shareholders who sell these
securities could receive less than the redemption value and could
incur certain transaction costs.

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. These documents
require notice of this disclaimer to be given in each agreement,
obligation, or instrument the Trust or its Trustees enter into or
sign.

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.

THE FUND'S TAX STATUS

To qualify for the special tax treatment afforded to regulated
investment companies, the Fund must, among other requirements: derive
at least 90% of its gross income from dividends, interest, and gains
from the sale of securities; derive less than 30% of its gross income
from the sale of securities held less than three months; invest in
securities within certain statutory limits; and distribute to its
shareholders at least 90% of its net income earned during the year.

PERFORMANCE INFORMATION

Performance depends upon such variables as: portfolio quality; average
portfolio maturity; type of instruments in which the portfolio is
invested; changes in interest rates; changes in expenses; and the
relative amount of cash flow. To the extent that financial
institutions and broker/dealers charge fees in connection with
services provided in conjunction with an investment in shares of the
Fund, the performance will be reduced for those shareholders paying
those fees.

YIELD

The yield is calculated based upon the seven days ending on the day of
the calculation, called the "base period." This yield is computed 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.

For the seven-day period ended July 31, 1997, the yield for Cash II
Shares was 4.96%, and the yield for Institutional Service Shares was
5.13%.

EFFECTIVE YIELD

The effective yield is calculated by compounding the unannualized
base-period return by: adding 1 to the base-period return; raising the
sum to the 365/7th power; and subtracting 1 from the result.

For the seven-day period ended July 31, 1997, the effective yield for
Cash II Shares was 5.08%, and the effective yield for Institutional
Service Shares was 5.26%.

TOTAL RETURN

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

The average annual total returns for the Institutional Service Shares
of the Fund for the one-, five-, and ten-year periods ended July 31,
1997, were 5.09%, 4.31%, and 5.69%, respectively.

Cumulative total return reflects the total performance over a specific
period of time. For the period from September 27, 1996 (date of
initial public investment) through July 31, 1997, the cumulative total
return for Cash II Shares was 4.14%. These total returns are
representative of only ten months of activity since the date of
initial public investment.

PERFORMANCE COMPARISONS

Investors may use financial publications and/or indices to obtain a
more complete view of the Fund's performance. When comparing
performance, investors should consider all relevant factors such as
the composition of any index used, prevailing market conditions,
portfolio compositions of other funds, and methods used to value
portfolio securities and compute offering price. The financial
publications and/or indices which the Fund uses in advertising may
include:

   * Lipper 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.

   * IBC/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.

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

   * Salomon 30-Day CD Index compares rate levels of 30-day
     certificates of deposit from the top ten prime representative
     banks.

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

ECONOMIC AND MARKET INFORMATION

GENERAL INFORMATION

The Trust was established as a Massachusetts business trust under a
Declaration of Trust dated October 3, 1988. The Declaration of Trust
permits the Trust to offer separate series of shares representing
interests in separate portfolios of securities. The shares in any one
portfolio may be offered in separate classes. With respect to this
Fund, as of the date of this prospectus, the Board of Trustees (the
"Trustees") has established two classes of shares known as
Institutional Shares and Institutional Service Shares. This prospectus
relates only to Institutional Shares of the Fund, which are designed
primarily for entities holding shares in an agency or fiduciary
capacity, financial institutions, financial intermediaries, and
institutional investors as a convenient means of accumulating an
interest in a professionally managed portfolio investing only in
short-term U.S. government securities. A minimum initial investment of
$1,000,000 is required.

The Fund attempts to stabilize the value of a share at $1.00. Shares
are currently sold and redeemed at that price.

INVESTMENT INFORMATION

INVESTMENT OBJECTIVE

The investment objective of the Fund is to provide current income
consistent with stability of principal and liquidity. This investment
objective cannot be changed without shareholder approval. While there
is no assurance that the Fund will achieve its investment objective,
it endeavors to do so by complying with the diversification and other
requirements of Rule 2a-7 under the Investment Company Act of 1940
which regulates money market mutual funds and by following the
investment policies described in this prospectus.

INVESTMENT POLICIES

The Fund pursues its investment objective by investing only in a
portfolio of U.S. government securities maturing in 13 months or less.
The average maturity of the securities in the Fund's portfolio,
computed on a dollar-weighted basis, will be 90 days or less. Unless
indicated otherwise, the investment policies may be changed by the
Trustees without shareholder approval. Shareholders will be notified
before any material change in these policies becomes effective.

The Fund will limit its investments to investments which, if owned
directly, pay interest exempt from state personal income tax.
Therefore, dividends paid by the Fund may be exempt from state
personal income tax.

ACCEPTABLE INVESTMENTS

The Fund invests only in U.S. government securities. These instruments are
either issued or guaranteed by the U.S. government, its agencies, or
instrumentalities. These securities include, but are not limited to:

   * direct obligations of the U.S. Treasury, such as U.S. Treasury bills,
     notes, and bonds;

   * notes, bonds, and discount notes issued or guaranteed by U.S.
     government agencies and instrumentalities supported by the full faith
     and credit of the United States;

   * notes, bonds, and discount notes of U.S. government agencies or
     instrumentalities which receive or have access to federal funding; and

   * notes, bonds, and discount notes of other U.S. government
     instrumentalities supported only by the credit of the

     instrumentalities.

Some obligations issued or guaranteed by agencies or instrumentalities of
the U.S. government are backed by the full faith and credit of the U.S.
Treasury. No assurances can be given that the U.S. government will provide
financial support to other agencies or instrumentalities, since it is not
obligated to do so. These instrumentalities are supported by:

   * the issuer's right to borrow an amount limited to a specific line of
     credit from the U.S. Treasury;

   * discretionary authority of the U.S. government to purchase certain
     obligations of an agency or instrumentality; or

   * the credit of the agency or instrumentality.

AGENCY MASTER DEMAND NOTES

The Fund may enter into master demand notes with various federal
agencies and instrumentalities. Under a master demand note, the Fund
has the right to increase or decrease the amount of the note on a
daily basis within specified maximum and minimum amounts. Master
demand notes also normally provide for full or partial repayment upon
seven or more days notice by either the Fund or the borrower and bear
interest at a variable rate. The Fund relies on master demand notes,
in part, to provide daily liquidity. To the extent that the Fund
cannot obtain liquidity through master demand notes, it may be
required to maintain a larger cash position, invest more assets in
securities with current maturities or dispose of assets at a gain or
loss to maintain sufficient liquidity.

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

The Fund may purchase securities on a when-issued or delayed delivery
basis. These transactions are arrangements in which the Fund purchases
securities with payment and delivery scheduled for a future time. The
seller's failure to complete these transactions may cause the Fund to
miss a price or yield considered to be advantageous. Settlement dates
may be a month or more after entering into these transactions, and the
market values of the securities purchased may vary from the purchase
prices.

The Fund may dispose of a commitment prior to settlement if the
adviser deems it appropriate to do so. In addition, the Fund may enter
into transactions to sell its purchase commitments to third parties at
current market values and simultaneously acquire other commitments to
purchase similar securities at later dates. The Fund may realize
short-term profits or losses upon the sale of such commitments.

INVESTMENT LIMITATIONS

The Fund will not borrow money directly or through reverse repurchase
agreements (arrangements in which the Fund sells a money market
instrument for a percentage of its cash value with an agreement to buy
it back on a set date) or pledge securities except, under certain
circumstances, the Fund may borrow up to one-third of the value of its
total assets and pledge assets to secure such borrowings.

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

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

FUND INFORMATION

MANAGEMENT OF THE FUND

BOARD OF TRUSTEES

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

INVESTMENT ADVISER

Investment decisions for the Fund are made by Federated Administrative
Services, the Fund's investment adviser, subject to direction by the
Trustees. The adviser continually conducts investment research and
supervision for the Fund and is responsible for the purchase and sale
of portfolio instruments.

Advisory Fees

The adviser receives an annual investment advisory fee equal to 0.20%
of the Fund's average daily net assets. The adviser may voluntarily
choose to waive a portion of its fee or reimburse other expenses of
the Fund, but reserves the right to terminate such waiver or
reimbursement at any time at its sole discretion.

Adviser's Background

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

Federated Administrative Services and other subsidiaries of Federated
Investors serve as investment advisers to a number of investment
companies and private accounts. Certain other subsidiaries also
provide administrative services to a number of investment companies.
With over $110 billion invested across over 300 funds under management
and/or administration by its subsidiaries, as of December 31, 1996,
Federated Investors is one of the largest mutual fund investment
managers in the United States. With more than 2,000 employees,
Federated continues to be led by the management who founded the
company in 1955. Federated funds are presently at work in and through
4,500 financial institutions nationwide.

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

DISTRIBUTION OF INSTITUTIONAL SHARES

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

Investors.

SHAREHOLDER SERVICES

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

SUPPLEMENTAL PAYMENTS TO FINANCIAL INSTITUTIONS

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

ADMINISTRATION OF THE FUND

ADMINISTRATIVE SERVICES

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

 MAXIMUM         AVERAGE AGGREGATE
   FEE            DAILY NET ASSETS

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

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

NET ASSET VALUE

The Fund attempts to stabilize the net asset value of shares at $1.00
by valuing the portfolio securities using the amortized cost method.
The net asset value per share is determined by subtracting liabilities
attributable to Institutional Shares from the value of Fund assets
attributable to Institutional Shares, and dividing the remainder by
the number of Institutional Shares outstanding. The Fund cannot
guarantee that its net asset value will always remain at $1.00 per
share.

The net asset value is determined at 1:00 p.m. (Eastern time) and as
of the close of trading (normally 4:00 p.m., Eastern time) on the New
York Stock Exchange, Monday through Friday, except on New Year's Day,
Martin Luther King Day, Presidents' Day, Good Friday, Memorial Day,
Independence Day,

Labor Day, Thanksgiving Day, and Christmas Day.

HOW TO PURCHASE SHARES

Shares are sold at their net asset value, without a sales charge, next
determined after an order is received, on days on which the New York
Stock Exchange is open for business. Shares may be purchased either by
wire or by check. The Fund reserves the right to reject any purchase
request.

To make a purchase, open an account by calling Federated Securities
Corp. Information needed to establish the account will be taken by
telephone. The minimum initial investment is $1,000,000. However, an
account may be opened with a smaller amount as long as the minimum is
reached within one year of opening the account. Financial institutions
may impose different minimum investment requirements on their
customers.

PURCHASING SHARES BY WIRE

Shares may be purchased by Federal Reserve wire by calling the Fund
before 2:00 p.m. (Eastern time) to place an order. The order is
considered received immediately. Payment by federal funds must be
received before 2:00 p.m. (Eastern time) that day. Federal funds
should be wired as follows: Federated Shareholder Services Company,
c/o State Street Bank and Trust Company, Boston, MA; Attention:
EDGEWIRE; For Credit to: Government Obligations Tax-Managed
Fund--Institutional Shares; Fund Number (this number can be found on
the account statement or by contacting the Fund); Group Number or
Order Number; Nominee or Institution Name; and ABA Number 011000028.
Shares cannot be purchased by wire on holidays when wire transfers are
restricted. Questions on wire purchases should be directed to your
shareholder services representative at the telephone number listed on
your account statement.

PURCHASING SHARES BY CHECK

Shares may be purchased by sending a check to Federated Shareholder
Services Company, P.O. Box 8600, Boston, MA 02266-8600. The check
should be made payable to: Government Obligations Tax-Managed
Fund--Institutional Shares. 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.

INVEST-BY-PHONE

Once an account has been opened, a shareholder may use invest-by-phone
for investments if an authorization form has been filed with Federated
Shareholder Services Company, the transfer agent for shares of the
Fund. Approximately two weeks after sending the form to Federated
Shareholder Services Company, the shareholder may call Federated
Shareholder Services Company to purchase shares. Federated Shareholder
Services Company will send a request for monies to the shareholder's
commercial bank, savings bank, or credit union ("bank") via the
Automated Clearing House. The shareholder's bank, which must be an
Automated Clearing House member, will then forward the monies to
Federated Shareholder Services Company. The purchase is normally
entered the next business day after the initial phone request. For
further information and an application, call the Fund.

HOW TO REDEEM SHARES

Shares are redeemed at their net asset value next determined after
Federated Shareholder Services Company receives the redemption
request. Redemptions will be made on days on which the Fund computes
its net asset value. Redemption requests must be received in proper
form and can be made as described below.

REDEEMING SHARES BY TELEPHONE

Redemptions in any amount may be made by calling the Fund provided the
Fund has a properly completed authorization form. These forms can be
obtained from Federated Securities Corp. Proceeds from redemption
requests received before 2:00 p.m. (Eastern time) will be wired the
same day to the shareholder's account at a domestic commercial bank
which is a member of the Federal Reserve System, but will not include
that day's dividend. Proceeds from redemption requests received after
that time include that day's dividend but will be wired the following
business day. Under limited circumstances, arrangements may be made
with the distributor for same-day payment of proceeds, without that
day's dividend, for redemption requests received after 2:00 p.m.
(Eastern time). Proceeds from redemption requests on holidays when
wire transfers are restricted will be wired the following business
day. Questions about telephone redemptions on days when wire transfers
are restricted should be directed to your shareholder services
representative at the telephone number listed on your account
statement.

Telephone instructions may be recorded and if reasonable procedures
are not followed by the Fund, it may be liable for losses due to
unauthorized or fraudulent telephone instructions.

In the event of drastic economic or market changes, a shareholder may
experience difficulty in redeeming by telephone. If this occurs,
"Redeeming Shares by Mail" should be considered. If at any time the
Fund shall determine it necessary to terminate or modify the telephone
redemption privilege, shareholders would be promptly notified.

REDEEMING SHARES BY MAIL

Shares may be redeemed in any amount by mailing a written request to:
Federated Shareholder Services Company, P.O. Box 8600, Boston, MA
02266-8600. If share certificates have been issued, they should be
sent unendorsed with the written request by registered or certified
mail to the address noted above.

The written request should state: the Fund name and the class
designation; the account name as registered with the Fund; the account
number; and the number of shares to be redeemed or the dollar amount
requested. All owners of the account must sign the request exactly as
the shares are registered. Normally, a check for the proceeds is
mailed within one business day, but in no event more than seven days,
after the receipt of a proper written redemption request. Dividends
are paid up to and including the day that a redemption request is
processed.

Shareholders requesting a redemption of any amount to be sent to an
address other than that on record with the Fund or a redemption
payable other than to the shareholder of record must have their
signatures guaranteed by a commercial or savings bank, trust company
or savings association whose deposits are insured by an organization
which is administered by the Federal Deposit Insurance Corporation; a
member firm of a domestic stock exchange; or any other "eligible
guarantor institution," as defined in the Securities Exchange Act of
1934. The Fund does not accept signatures guaranteed by a notary
public.

ACCOUNT AND SHARE INFORMATION

DIVIDENDS

Dividends are declared daily and paid monthly. Dividends are
automatically reinvested on payment dates in additional shares of the
Fund unless cash payments are requested by writing to the Fund. Shares
purchased by wire before 2:00 p.m. (Eastern time) begin earning
dividends that day. Shares purchased by check begin earning dividends
the day after the check is converted into federal funds.

CAPITAL GAINS

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 will distribute in cash or
additional shares any realized net long-term capital gains at least
once every 12 months.

CONFIRMATIONS AND ACCOUNT STATEMENTS

Shareholders will receive detailed confirmations of transactions
(except for systematic program transactions). In addition,
shareholders will receive periodic statements reporting all account
activity, including dividends paid. The Fund will not issue share
certificates.

ACCOUNTS WITH LOW BALANCES

Due to the high cost of maintaining accounts with low balances, the
Fund may redeem shares in any account, except accounts maintained by
retirement plans, and pay the proceeds to the shareholder if the
account balance falls below a required minimum value of $1,000,000 due
to shareholder redemptions. Before shares are redeemed to close an
account, the shareholder is notified in writing and allowed 30 days to
purchase additional shares to meet the minimum requirement.

VOTING RIGHTS

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

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

TAX INFORMATION

FEDERAL INCOME TAX

The Fund will pay no federal income tax because it expects to meet
requirements of the Internal Revenue Code applicable to regulated
investment companies and to receive the special tax treatment afforded
to such companies. The Fund will be treated as a single, separate
entity for federal income tax purposes so that income (including
capital gains) and losses realized by the Trust's other portfolios
will not be combined for tax purposes with those realized by the Fund.

Unless otherwise exempt, shareholders are required to pay federal
income tax on any dividends and other distributions received. This
applies whether dividends and distributions are received in cash or as
additional shares.

STATE AND LOCAL TAXES

In the opinion of Houston, Donnelly & Meck, counsel to the Trust, Fund
shares may be subject to personal property taxes imposed by counties,
municipalities, and school districts in Pennsylvania to the extent
that the portfolio securities in the Fund would be subject to such
taxes if owned directly by residents of those jurisdictions.

The Fund will limit its investments to those which, if owned directly,
pay interest exempt from state personal income tax. However, under the
laws of some states, the net investment income distributed by the Fund
may be taxable to shareholders. Shareholders are urged to consult
their own tax advisers regarding the status of their accounts under
state and local tax laws.

OTHER CLASSES OF SHARES

The Fund also offers other classes. Institutional Service Shares are
sold at net asset value primarily to financial institutions, financial
intermediaries and institutional investors, and are subject to a

Institutional Service Shares are distributed with no 12b-1 Plan but
are subject to shareholder services fees.

Expense differences between classes may affect the performance of each
class.

investors may call 1-800-341-7400.

PERFORMANCE INFORMATION

From time to time, the Fund advertises its yield, effective yield and
total return. The performance figures will be calculated separately
for each class of shares.

Yield represents the annualized rate of income earned on an investment
over a seven-day period. It is the annualized dividends earned during
the period on an investment shown as a percentage of the investment.
The effective yield is calculated similarly to the yield, but when
annualized, the income earned by an investment is assumed to be
reinvested daily. The effective yield will be slightly higher than the
yield because of the compounding effect of this assumed reinvestment.

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

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

NOTES TO FINANCIAL STATEMENTS

GOVERNMENT OBLIGATIONS TAX-MANAGED FUND

JULY 31, 1997

ORGANIZATION

Money Market Obligations Trust (the "Trust") is registered under the
Investment Company Act of 1940, as amended (the "Act") as an open-end,
management investment company. The Trust consists of six portfolios.
The financial statements included herein are only those of Government
Obligations Tax-Managed Fund (the "Fund"). The financial statements of
the other portfolios are presented separately. The assets of each
portfolio are segregated and a shareholder's interest is limited to
the portfolio in which shares are held. The investment objective of
the Fund is to provide current income consistent with stability of
principal and liquidity.

The Fund offers two classes of shares: Institutional Shares and
Institutional Service Shares.

SIGNIFICANT ACCOUNTING POLICIES

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

INVESTMENT VALUATIONS

The Fund uses the amortized cost method to value its portfolio
securities in accordance with Rule 2a-7 under the Act.

INVESTMENT INCOME, EXPENSES AND DISTRIBUTIONS

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

FEDERAL TAXES

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

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

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

DEFERRED EXPENSES

The costs incurred by the Fund with respect to registration of its
shares in its first fiscal year, excluding the initial expense of
registering its shares, have been deferred and are being amortized
using the straight-line method over a period of five years from the
Fund's commencement date.

USE OF ESTIMATES

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

OTHER

Investment transactions are accounted for on the trade date.

SHARES OF BENEFICIAL INTEREST

The Declaration of Trust permits the Trustees to issue an unlimited
number of full and fractional shares of beneficial interest (without
par value) for each class of shares. At July 31, 1997, capital paid-in
aggregated $931,777,644. Transactions in shares were as follows:

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Shareholders and Board of Trustees of MONEY MARKET OBLIGATIONS
TRUST (Government Obligations Tax-Managed Fund):

We have audited the accompanying statement of assets and liabilities
of Government Obligations Tax-Managed Fund (an investment portfolio of
Money Market Obligations Trust, a Massachusetts business trust),
including the schedule of portfolio investments, as of July 31, 1997,
the related statement of operations for the year then ended, the
statement of changes in net assets for each of the two years in the
period then ended, and the financial highlights for the periods
presented. These financial statements and financial highlights are the
responsibility of the Trust's management. Our responsibility is to
express an opinion on these financial statements and financial
highlights based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements
and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts
and disclosures in the financial statements. Our procedures included
confirmation of securities owned as of July 31, 1997, by
correspondence with the custodian and brokers. An audit also includes
assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights
referred to above present fairly, in all material respects, the
financial position of Government Obligations Tax-Managed Fund (an
investment portfolio of Money Market Obligations Trust) as of July 31,
1997, the results of its operations for the year then ended, the
changes in its net assets for each of the two years in the period then
ended, and its financial highlights for the periods presented, in
conformity with generally accepted accounting principles.

GENERAL INFORMATION

The Trust was established as a Massachusetts business trust under a
Declaration of Trust dated October 3, 1988. The Declaration of Trust
permits the Trust to offer separate series of shares representing
interests in separate portfolios of securities. The shares in any one
portfolio may be offered in separate classes. With respect to this
Fund, as of the date of this prospectus, the Board of Trustees (the
"Trustees") has established two classes of shares known as
Institutional Service Shares and Institutional Shares. This prospectus
relates only to Institutional Service Shares of the Fund, which are
designed primarily for financial institutions, financial
intermediaries, and institutional investors as a convenient means of
accumulating an interest in a professionally managed portfolio
investing only in short-term U.S. government securities. A minimum
initial investment of $1,000,000 is required.

The Fund attempts to stabilize the value of a share at $1.00. Shares
are currently sold and redeemed at that price.

INVESTMENT INFORMATION

INVESTMENT OBJECTIVE

The investment objective of the Fund is to provide current income
consistent with stability of principal and liquidity. This investment
objective cannot be changed without shareholder approval. While there
is no assurance that the Fund will achieve its investment objective,
it endeavors to do so by complying with the diversification and other
requirements of Rule 2a-7 under the Investment Company Act of 1940
which regulates money market mutual funds and by following the
investment policies described in this prospectus.

INVESTMENT POLICIES

The Fund pursues its investment objective by investing only in a
portfolio of U.S. government securities maturing in 13 months or less.
The average maturity of the securities in the Fund's portfolio,
computed on a dollar-weighted basis, will be 90 days or less. Unless
indicated otherwise, the investment policies may be changed by the
Trustees without shareholder approval. Shareholders will be notified
before any material change in these policies becomes effective.

The Fund will limit its investments to investments which, if owned
directly, pay interest exempt from state personal income tax.
Therefore, dividends paid by the Fund may be exempt from state
personal income tax.

The Fund invests only in U.S. government securities. These instruments are
either issued or guaranteed by the U.S. government, its agencies, or
instrumentalities. These securities include, but are not limited to:

   * direct obligations of the U.S. Treasury, such as U.S. Treasury bills,
     notes, and bonds;

   * notes, bonds, and discount notes issued or guaranteed by U.S.
     government agencies and instrumentalities supported by the full faith
     and credit of the United States;

   * notes, bonds, and discount notes of U.S. government agencies or
     instrumentalities which receive or have access to federal funding; and

   * notes, bonds, and discount notes of other U.S. government
     instrumentalities supported only by the credit of the

     instrumentalities.

Some obligations issued or guaranteed by agencies or instrumentalities of
the U.S. government are backed by the full faith and credit of the U.S.
Treasury. No assurances can be given that the U.S. government will provide
financial support to other agencies or instrumentalities, since it is not
obligated to do so. These instrumentalities are supported by:

   * the issuer's right to borrow an amount limited to a specific line of
     credit from the U.S. Treasury;

   * discretionary authority of the U.S. government to purchase certain
     obligations of an agency or instrumentality; or

   * the credit of the agency or instrumentality.

AGENCY MASTER DEMAND NOTES

The Fund may enter into master demand notes with various federal
agencies and instrumentalities. Under a master demand note, the Fund
has the right to increase or decrease the amount of the note on a
daily basis within specified maximum and minimum amounts. Master
demand notes also normally provide for full or partial repayment upon
seven or more days notice by either the Fund or the borrower and bear
interest at a variable rate. The Fund relies on master demand notes,
in part, to provide daily liquidity. To the extent that the Fund
cannot obtain liquidity through master demand notes, it may be
required to maintain a larger cash position, invest more assets in
securities with current maturities or dispose of assets at a gain or
loss to maintain sufficient liquidity.

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

The Fund may purchase securities on a when-issued or delayed delivery
basis. These transactions are arrangements in which the Fund purchases
securities with payment and delivery scheduled for a future time. The
seller's failure to complete these transactions may cause the Fund to
miss a price or yield considered to be advantageous. Settlement dates
may be a month or more after entering into these transactions, and the
market values of the securities purchased may vary from the purchase
prices.

The Fund may dispose of a commitment prior to settlement if the
adviser deems it appropriate to do so. In addition, the Fund may enter
into transactions to sell its purchase commitments to third parties at
current market values and simultaneously acquire other commitments to
purchase similar securities at later dates. The Fund may realize
short-term profits or losses upon the sale of such commitments.

INVESTMENT LIMITATIONS

The Fund will not borrow money directly or through reverse repurchase
agreements (arrangements in which the Fund sells a money market
instrument for a percentage of its cash value with an agreement to buy
it back on a set date) or pledge securities except, under certain
circumstances, the Fund may borrow up to one-third of the value of its
total assets and pledge assets to secure such borrowings.

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

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

FUND INFORMATION

MANAGEMENT OF THE FUND

BOARD OF TRUSTEES

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

INVESTMENT ADVISER

Investment decisions for the Fund are made by Federated Administrative
Services, the Fund's investment adviser, subject to direction by the
Trustees. The adviser continually conducts investment research and
supervision for the Fund and is responsible for the purchase and sale
of portfolio instruments.

Advisory Fees

The adviser receives an annual investment advisory fee equal to 0.20%
of the Fund's average daily net assets. The adviser may voluntarily
choose to waive a portion of its fee or reimburse other expenses of
the Fund, but reserves the right to terminate such waiver or
reimbursement at any time at its sole discretion.

Adviser's Background

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

Federated Administrative Services and other subsidiaries of Federated
Investors serve as investment advisers to a number of investment
companies and private accounts. Certain other subsidiaries also
provide administrative services to a number of investment companies.
With over $110 billion invested across over 300 funds under management
and/or administration by its subsidiaries, as of December 31, 1996,
Federated Investors is one of the largest mutual fund investment
managers in the United States. With more than 2,000 employees,
Federated continues to be led by the management who founded the
company in 1955. Federated funds are presently at work in and through
4,500 financial institutions nationwide.

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

DISTRIBUTION OF INSTITUTIONAL SERVICE SHARES

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

Federated Investors.

SHAREHOLDER SERVICES

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

SUPPLEMENTAL PAYMENTS TO FINANCIAL INSTITUTIONS

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

ADMINISTRATION OF THE FUND

ADMINISTRATIVE SERVICES

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

 MAXIMUM         AVERAGE AGGREGATE
   FEE            DAILY NET ASSETS

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

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

NET ASSET VALUE

The Fund attempts to stabilize the net asset value of shares at $1.00
by valuing the portfolio securities using the amortized cost method.
The net asset value per share is determined by subtracting liabilities
attributable to Institutional Service Shares from the value of Fund
assets attributable to Institutional Service Shares, and dividing the
remainder by the number of Institutional Service Shares outstanding.
The Fund cannot guarantee that its net asset value will always remain
at $1.00 per share.

The net asset value is determined at 1:00 p.m. (Eastern time) and as
of the close of trading (normally 4:00 p.m., Eastern time) on the New
York Stock Exchange, Monday through Friday, except on New Year's Day,
Martin Luther King Day, Presidents' Day, Good Friday, Memorial Day,
Independence Day,

Labor Day, Thanksgiving Day, and Christmas Day.

HOW TO PURCHASE SHARES

Shares are sold at their net asset value, without a sales charge, next
determined after an order is received, on days on which the New York
Stock Exchange is open for business. Shares may be purchased either by
wire or by check. The Fund reserves the right to reject any purchase
request.

To make a purchase, open an account by calling Federated Securities
Corp. Information needed to establish the account will be taken by
telephone. The minimum initial investment is $1,000,000. However, an
account may be opened with a smaller amount as long as the minimum is
reached within one year of opening the account. Financial institutions
may impose different minimum investment requirements on their
customers.

PURCHASING SHARES BY WIRE

Shares may be purchased by Federal Reserve wire by calling the Fund
before 2:00 p.m. (Eastern time) to place an order. The order is
considered received immediately. Payment by federal funds must be
received before 2:00 p.m. (Eastern time) that day. Federal funds
should be wired as follows: Federated Shareholder Services Company,
c/o State Street Bank and Trust Company, Boston, MA; Attention:
EDGEWIRE; For Credit to: Government Obligations Tax-Managed
Fund--Institutional Service Shares; Fund Number (this number can be
found on the account statement or by contacting the Fund); Group
Number or Order Number; Nominee or Institution Name; and ABA Number
011000028. Shares cannot be purchased by wire on holidays when wire
transfers are restricted. Questions on wire purchases should be
directed to your shareholder services representative at the telephone
number listed on your account statement.

PURCHASING SHARES BY CHECK

Shares may be purchased by sending a check to Federated Shareholder
Services Company, P.O. Box 8600, Boston, MA 02266-8600. The check
should be made payable to: Government Obligations Tax-Managed
Fund--Institutional Service Shares. 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.

INVEST-BY-PHONE

Once an account has been opened, a shareholder may use invest-by-phone
for investments if an authorization form has been filed with Federated
Shareholder Services Company, the transfer agent for shares of the
Fund. Approximately two weeks after sending the form to Federated
Shareholder Services Company, the shareholder may call Federated
Shareholder Services Company to purchase shares. Federated Shareholder
Services Company will send a request for monies to the shareholder's
commercial bank, savings bank, or credit union ("bank") via the
Automated Clearing House. The shareholder's bank, which must be an
Automated Clearing House member, will then forward the monies to
Federated Shareholder Services Company. The purchase is normally
entered the next business day after the initial phone request. For
further information and an application, call the Fund.

HOW TO REDEEM SHARES

Shares are redeemed at their net asset value next determined after
Federated Shareholder Services Company receives the redemption
request. Redemptions will be made on days on which the Fund computes
its net asset value. Redemption requests must be received in proper
form and can be made as described below.

REDEEMING SHARES BY TELEPHONE

Redemptions in any amount may be made by calling the Fund provided the
Fund has a properly completed authorization form. These forms can be
obtained from Federated Securities Corp. Proceeds from redemption
requests received before 2:00 p.m. (Eastern time) will be wired the
same day to the shareholder's account at a domestic commercial bank
which is a member of the Federal Reserve System, but will not include
that day's dividend. Proceeds from redemption requests received after
that time include that day's dividend but will be wired the following
business day. Under limited circumstances, arrangements may be made
with the distributor for same-day payment of proceeds, without that
day's dividend, for redemption requests received after 2:00 p.m.
(Eastern time). Proceeds from redemption requests on holidays when
wire transfers are restricted will be wired the following business
day. Questions about telephone redemptions on days when wire transfers
are restricted should be directed to your shareholder services
representative at the telephone number listed on your account
statement.

Telephone instructions may be recorded and if reasonable procedures
are not followed by the Fund, it may be liable for losses due to
unauthorized or fraudulent telephone instructions.

In the event of drastic economic or market changes, a shareholder may
experience difficulty in redeeming by telephone. If this occurs,
"Redeeming Shares by Mail" should be considered. If at any time the
Fund shall determine it necessary to terminate or modify the telephone
redemption privilege, shareholders would be promptly notified.

REDEEMING SHARES BY MAIL

Shares may be redeemed in any amount by mailing a written request to:
Federated Shareholder Services Company, P.O. Box 8600, Boston, MA
02266-8600. If share certificates have been issued, they should be
sent unendorsed with the written request by registered or certified
mail to the address noted above.

The written request should state: the Fund name and the class
designation; the account name as registered with the Fund; the account
number; and the number of shares to be redeemed or the dollar amount
requested. All owners of the account must sign the request exactly as
the shares are registered. Normally, a check for the proceeds is
mailed within one business day, but in no event more than seven days,
after the receipt of a proper written redemption request. Dividends
are paid up to and including the day that a redemption request is
processed.

Shareholders requesting a redemption of any amount to be sent to an
address other than that on record with the Fund or a redemption
payable other than to the shareholder of record must have their
signatures guaranteed by a commercial or savings bank, trust company
or savings association whose deposits are insured by an organization
which is administered by the Federal Deposit Insurance Corporation; a
member firm of a domestic stock exchange; or any other "eligible
guarantor institution," as defined in the Securities Exchange Act of
1934. The Fund does not accept signatures guaranteed by a notary
public.

ACCOUNT AND SHARE INFORMATION

DIVIDENDS

Dividends are declared daily and paid monthly. Dividends are
automatically reinvested on payment dates in additional shares of the
Fund unless cash payments are requested by writing to the Fund. Shares
purchased by wire before 2:00 p.m. (Eastern time) begin earning
dividends that day. Shares purchased by check begin earning dividends
the day after the check is converted into federal funds.

CAPITAL GAINS

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 will distribute in cash or
additional shares any realized net long-term capital gains at least
once every 12 months.

CONFIRMATIONS AND ACCOUNT STATEMENTS

Shareholders will receive detailed confirmations of transactions
(except for systematic program transactions). In addition,
shareholders will receive periodic statements reporting all account
activity, including dividends paid. The Fund will not issue share
certificates.

ACCOUNTS WITH LOW BALANCES

Due to the high cost of maintaining accounts with low balances, the
Fund may redeem shares in any account, except accounts maintained by
retirement plans, and pay the proceeds to the shareholder if the
account balance falls below a required minimum value of $1,000,000 due
to shareholder redemptions. Before shares are redeemed to close an
account, the shareholder is notified in writing and allowed 30 days to
purchase additional shares to meet the minimum requirement.

VOTING RIGHTS

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

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

TAX INFORMATION

FEDERAL INCOME TAX

The Fund will pay no federal income tax because it expects to meet
requirements of the Internal Revenue Code applicable to regulated
investment companies and to receive the special tax treatment afforded
to such companies. The Fund will be treated as a single, separate
entity for federal income tax purposes so that income (including
capital gains) and losses realized by the Trust's other portfolios
will not be combined for tax purposes with those realized by the Fund.

Unless otherwise exempt, shareholders are required to pay federal
income tax on any dividends and other distributions received. This
applies whether dividends and distributions are received in cash or as
additional shares.

STATE AND LOCAL TAXES

In the opinion of Houston, Donnelly & Meck, counsel to the Trust, Fund
shares may be subject to personal property taxes imposed by counties,
municipalities, and school districts in Pennsylvania to the extent
that the portfolio securities in the Fund would be subject to such
taxes if owned directly by residents of those jurisdictions.

The Fund will limit its investments to those which, if owned directly,
pay interest exempt from state personal income tax. However, under the
laws of some states, the net investment income distributed by the Fund
may be taxable to shareholders. Shareholders are urged to consult
their own tax advisers regarding the status of their accounts under
state and local tax laws.

OTHER CLASSES OF SHARES

The Fund also offers other classes. Institutional Shares are sold at
net asset value primarily to financial institutions, financial
intermediaries, institutional investors, and entities holding shares
in an agency or fiduciary capacity, and are subject to a minimum
initial investment of $1,000,000.

All classes are subject to certain of the same expenses.

Institutional Shares are distributed with no 12b-1 Plan but are
subject to shareholder services fees.

Expense differences between classes may affect the performance of each
class.

To obtain more information and a prospectus for any other class,
investors may call 1-800-341-7400.

PERFORMANCE INFORMATION

From time to time, the Fund advertises its yield, effective yield and
total return. The performance figures will be calculated separately
for each class of shares.

Yield represents the annualized rate of income earned on an investment
over a seven-day period. It is the annualized dividends earned during
the period on an investment shown as a percentage of the investment.
The effective yield is calculated similarly to the yield, but when
annualized, the income earned by an investment is assumed to be
reinvested daily. The effective yield will be slightly higher than the
yield because of the compounding effect of this assumed reinvestment.

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

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

NOTES TO FINANCIAL STATEMENTS

GOVERNMENT OBLIGATIONS TAX-MANAGED FUND

JULY 31, 1997

ORGANIZATION

Money Market Obligations Trust (the "Trust") is registered under the
Investment Company Act of 1940, as amended (the "Act") as an open-end,
management investment company. The Trust consists of six portfolios.
The financial statements included herein are only those of Government
Obligations Tax-Managed Fund (the "Fund"). The financial statements of
the other portfolios are presented separately. The assets of each
portfolio are segregated and a shareholder's interest is limited to
the portfolio in which shares are held. The investment objective of
the Fund is to provide current income consistent with stability of
principal and liquidity.

The Fund offers two classes of shares: Institutional Shares and
Institutional Service Shares.

SIGNIFICANT ACCOUNTING POLICIES

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

INVESTMENT VALUATIONS

The Fund uses the amortized cost method to value its portfolio
securities in accordance with Rule 2a-7 under the Act.

INVESTMENT INCOME, EXPENSES AND DISTRIBUTIONS

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

FEDERAL TAXES

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

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

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

DEFERRED EXPENSES

The costs incurred by the Fund with respect to registration of its
shares in its first fiscal year, excluding the initial expense of
registering its shares, have been deferred and are being amortized
using the straight-line method over a period of five years from the
Fund's commencement date.

USE OF ESTIMATES

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

OTHER

Investment transactions are accounted for on the trade date.

SHARES OF BENEFICIAL INTEREST

The Declaration of Trust permits the Trustees to issue an unlimited
number of full and fractional shares of beneficial interest (without
par value) for each class of shares. At July 31, 1997, capital paid-in
aggregated $931,777,644. Transactions in shares were as follows:

can modify or terminate this voluntary waiver at any time at its sole
discretion.

ADMINISTRATIVE FEE

Federated Services Company ("FServ"), under the Administrative

at any time at its sole discretion.

TRANSFER AND DIVIDEND DISBURSING AGENT FEES AND EXPENSES

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS

To the Shareholders and Board of Trustees of MONEY MARKET OBLIGATIONS
TRUST (Government Obligations Tax-Managed Fund):

We have audited the accompanying statement of assets and liabilities
of Government Obligations Tax-Managed Fund (an investment portfolio of
Money Market Obligations Trust, a Massachusetts business trust),
including the schedule of portfolio investments, as of July 31, 1997,
the related statement of operations for the year then ended, the
statement of changes in net assets for each of the two years in the
period then ended, and the financial highlights for the periods
presented. These financial statements and financial highlights are the
responsibility of the Trust's management. Our responsibility is to
express an opinion on these financial statements and financial
highlights based on our audits.

We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit
to obtain reasonable assurance about whether the financial statements
and financial highlights are free of material misstatement. An audit
includes examining, on a test basis, evidence supporting the amounts
and disclosures in the financial statements. Our procedures included
confirmation of securities owned as of July 31, 1997, by
correspondence with the custodian and brokers. An audit also includes
assessing the accounting principles used and significant estimates
made by management, as well as evaluating the overall financial
statement presentation. We believe that our audits provide a
reasonable basis for our opinion.

In our opinion, the financial statements and financial highlights
referred to above present fairly, in all material respects, the
financial position of Government Obligations Tax-Managed Fund (an
investment portfolio of Money Market Obligations Trust) as of July 31,
1997, the results of its operations for the year then ended, the
changes in its net assets for each of the two years in the period then
ended, and its financial highlights for the periods presented, in
conformity with generally accepted accounting principles.

INVESTMENT POLICIES

Unless indicated otherwise, the policies described below may be
changed by the Board of Trustees (the "Trustees") without shareholder
approval. Shareholders will be notified before any material change in
these policies becomes effective.

ACCEPTABLE INVESTMENTS

Some of the short-term U.S. government securities the Fund may
purchase carry variable interest rates. These securities have a rate
of interest subject to adjustment at least annually. This adjusted
interest rate is ordinarily tied to some objective standard, such as
the 91-day U.S. Treasury bill rate. Variable interest rates will
reduce the changes in the market value of such securities from their
original purchase prices. Accordingly, the potential for capital
appreciation or capital depreciation should not be greater than that
of fixed-interest-rate U.S. government securities having maturities
equal to the interest rate adjustment dates of the variable-rate U.S.
government securities. The Fund may purchase variable-rate U.S.
government securities upon the determination by the Trustees that the
interest rate as adjusted will cause the instrument to have a current
market value that approximates its par value on the adjustment date.

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

These transactions are made to secure what is considered to be an
advantageous price or yield for the Fund. No fees or other expenses,
other than normal transaction costs, are incurred. However, liquid
assets of the Fund in a dollar amount sufficient to make payment for
the securities to be purchased are: segregated on the Fund's records
at the trade date; marked to market daily; and maintained until the
transaction is settled. The Fund does not intend to engage in
when-issued and delayed delivery transactions to an extent that would
cause the segregation of more than 20% of the total value of its
assets.

REVERSE REPURCHASE AGREEMENTS

The Fund may also enter into reverse repurchase agreements. These
transactions are similar to borrowing cash. In a reverse repurchase
agreement, the Fund transfers possession of a portfolio instrument in
return for a percentage of the instrument's market value in cash and
agrees that on a stipulated date in the future the Fund will
repurchase the portfolio instrument by remitting the original
consideration plus interest at an agreed-upon rate. The use of reverse
repurchase agreements may enable the Fund to avoid selling portfolio
instruments at a time when a sale may be deemed to be disadvantageous,
but does not ensure this result. However, liquid assets of the Fund,
in a dollar amount sufficient to make payment for the securities to be
purchased, are: segregated on the Fund's records at the trade date;
marked to market daily; and maintained until the transaction is
settled.

INVESTMENT LIMITATIONS

SELLING SHORT AND BUYING ON MARGIN

The Fund will not sell any securities short or purchase any securities
on margin but may obtain such short-term credits as are necessary for
clearance of transactions.

ISSUING SENIOR SECURITIES AND BORROWING MONEY

The Fund will not issue senior securities except that the Fund may
borrow money directly or through reverse repurchase agreements in
amounts up to one-third of the value of its total assets, including
the amounts borrowed.

The Fund will not borrow money or engage in reverse repurchase
agreements for investment leverage, but rather as a temporary,
extraordinary, or emergency measure or to facilitate management of the
portfolio by enabling the Fund to meet redemption requests when the
liquidation of portfolio securities is deemed to be inconvenient or
disadvantageous. The Fund will not purchase any securities while
borrowings in excess of 5% of the value of its total assets are
outstanding. During the period any reverse repurchase agreements are
outstanding, the Fund will restrict the purchase of portfolio
securities to money market instruments maturing on or before the
expiration date of the reverse repurchase agreements, but only to the
extent necessary to assure completion of the reverse repurchase
agreements.

PLEDGING ASSETS

The Fund will not mortgage, pledge, or hypothecate any assets except
as necessary to secure permitted borrowings.

LENDING CASH OR SECURITIES

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

INVESTING IN COMMODITIES

The Fund will not purchase or sell commodities, commodity contracts,
or commodity futures contracts.

INVESTING IN REAL ESTATE

The Fund will not purchase or sell real estate, including limited
partnership interests, although it may invest in securities of issuers
whose business involves the purchase or sale of real estate or in
securities which are secured by real estate or interests in real
estate.

UNDERWRITING

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

CONCENTRATION OF INVESTMENTS

The Fund will not invest 25% or more of the value of its total assets in any
one industry. The U.S. government is not considered to be an industry.

DIVERSIFICATION OF INVESTMENTS

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, or 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) if as a result more than 5% of the value of its total
assets would be invested in the securities of that issuer, or if it
would own more than 10% of the outstanding voting securities of that
issuer.

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

INVESTING IN ILLIQUID SECURITIES

The Fund will not invest more than 10% of the value of its net assets
in illiquid securities.

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.

INVESTING FOR CONTROL

The Fund will not invest in securities of a company for the purpose of
exercising control or management.

INVESTING IN OPTIONS

The Fund will not invest in puts, calls, straddles, spreads, or any
combination of them.

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.

The Fund did not borrow money or pledge securities in excess of 5% of
the value of its net assets during the last fiscal year and has no
present intent to do so during the coming fiscal year.

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, which regulates money market mutual funds.
The Fund will determine the effective maturity of its investments
according to Rule 2a-7. The Fund may change these operational policies
to reflect changes in the laws and regulations without the approval of
its shareholders.

TRUSTEE LIABILITY

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

INVESTMENT ADVISORY SERVICES

INVESTMENT ADVISER

The Fund's investment adviser is Federated Administrative Services. It is a
subsidiary of Federated Investors. All the voting securities of Federated
Investors are owned by a trust, the trustees of which are John F. Donahue,

his wife and his son, J. Christopher Donahue.

The adviser shall not be liable to the Trust, the Fund, or any
shareholder of the Fund for any losses that may be sustained in the
purchase, holding, or sale of any security or for anything done or
omitted by it, except acts or omissions involving willful misfeasance,
bad faith, gross negligence, or reckless disregard of the duties
imposed upon it by its contract with the Fund.

ADVISORY FEES

For its advisory services, Federated Administrative Services receives
an annual investment advisory fee as described in the prospectus. For
the fiscal years ended July 31, 1997 and 1996, and for the period from
May 30, 1995 (date of initial public investment) to July 31, 1995, the
adviser earned $1,452,990, $692,278, and $24,484, respectively, of
which $923,964, $664,948, and $24,484, respectively, were waived.

BROKERAGE TRANSACTIONS

When selecting brokers and dealers to handle the purchase and sale of
portfolio instruments, the adviser looks for prompt execution of the
order at a favorable price. In working with dealers, the adviser will
generally use those who are recognized dealers in specific portfolio
instruments, except when a better price and execution of the order can
be obtained elsewhere. The adviser makes decisions on portfolio
transactions and selects brokers and dealers subject to guidelines
established by the Trustees. The adviser may select brokers and
dealers who offer brokerage and research services. These services may
be furnished directly to the Fund or to the adviser and may include:
advice as to the advisability of investing in securities; security
analysis and reports; economic studies; industry studies; receipt of
quotations for portfolio evaluations; and similar services. Research
services provided by brokers and dealers may be used by the adviser or
its affiliates in advising the Fund and other accounts. To the extent
that receipt of these services may supplant services for which the
adviser or its affiliates might otherwise have paid, it would tend to
reduce their expenses. The adviser and its affiliates exercise
reasonable business judgment in selecting brokers who offer brokerage
and research services to execute securities transactions. They
determine in good faith that commissions charged by such persons are
reasonable in relationship to the value of the brokerage and research
services provided. During the fiscal years ended July 31, 1997 and
1996, and for the period from May 30, 1995 (date of initial public
investment) to July 31, 1995, the Fund paid no brokerage commissions.

Although investment decisions for the Fund are made independently from
those of the other accounts managed by the adviser, investments of the
type the Fund may make may also be made by those other accounts. When
the Fund and one or more other accounts managed by the adviser are
prepared to invest in, or desire to dispose of, the same security,
available investments or opportunities for sales will be allocated in
a manner believed by the adviser to be equitable to each. In some
cases, this procedure may adversely affect the price paid or received
by the Fund or the size of the position obtained or disposed of by the
Fund. In other cases, however, it is believed that coordination and
the ability to participate in volume transactions will be to the
benefit of the Fund.

OTHER SERVICES

FUND ADMINISTRATION

Federated Services Company, a subsidiary of Federated Investors,
provides administrative personnel and services to the Fund for a fee
as described in the prospectus. From March 1, 1994 to March 1, 1996,
Federated Administrative Services, a subsidiary of Federated
Investors, served as the Fund's Administrator. For purposes of this
Statement of Additional Information, Federated Services Company and
Federated Administrative Services may hereinafter collectively be
referred to as the "Administrators." For the fiscal years ended July
31, 1997 and 1996, and for the period from May 30, 1995 (date of
initial public investment) to July 31, 1995, the Administrators earned
$548,677, $261,681, and $26,329, respectively.

CUSTODIAN AND PORTFOLIO ACCOUNTANT

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

TRANSFER AGENT

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

INDEPENDENT PUBLIC ACCOUNTANTS

The independent public accountants for the Fund are Arthur Andersen
LLP, Pittsburgh, Pennsylvania.

SHAREHOLDER SERVICES

This arrangement permits the payment of fees to Federated Shareholder
Services to cause services to be provided which are necessary for the
maintenance of shareholder accounts and to encourage personal services
to shareholders by a representative who has knowledge of the
shareholder's particular circumstances and goals. These activities and
services may include but are not limited to providing office space,
equipment, telephone facilities, and various clerical, supervisory,
computer, and other personnel as necessary or beneficial to establish
and maintain shareholder accounts and records; processing purchase and
redemption transactions and automatic investments of client account
cash balances; answering routine client inquiries; and assisting
clients in changing dividend options, account designations, and
addresses.

By adopting the Shareholder Services Agreement, the Trustees expect
that the Fund will benefit by: (1) providing personal services to
shareholders; (2) investing shareholder assets with a minimum of delay
and administrative detail; (3) enhancing shareholder recordkeeping
systems; and (4) responding promptly to shareholders' requests and
inquiries concerning their accounts.

For the fiscal year ended July 31, 1997, the Fund earned shareholder
service fees on behalf of Institutional Shares and Institutional
Service Shares in the amounts of $746,763 and $1,069,476,
respectively, $0 and $1,069,476 of which, respectively, was paid to
financial institutions.

DETERMINING NET ASSET VALUE

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 Rule
2a-7 (the "Rule") promulgated by the Securities and Exchange
Commission under the Investment Company Act of 1940. 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.

REDEMPTION IN KIND

The Fund is obligated to redeem shares solely in cash up to $250,000
or 1% of the Fund's net asset value, whichever is less, for any one
shareholder within a 90-day period. Any redemption beyond this amount
will also be in cash unless the Trustees determine that further
payments should be in kind. In such cases, the Fund will pay all or a
portion of the remainder of the redemption in portfolio instruments
valued in the same way as the Fund determines net asset value. The
portfolio instruments will be selected in a manner that the Trustees
deem fair and equitable. Redemption in kind is not as liquid as a cash
redemption. If redemption is made in kind, shareholders who sell these
securities could receive less than the redemption value and could
incur certain transaction costs.

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. These documents
require notice of this disclaimer to be given in each agreement,
obligation, or instrument the Trust or its Trustees enter into or
sign.

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.

THE FUND'S TAX STATUS

To qualify for the special tax treatment afforded to regulated
investment companies, the Fund must, among other requirements: derive
at least 90% of its gross income from dividends, interest, and gains
from the sale of securities; derive less than 30% of its gross income
from the sale of securities held less than three months; invest in
securities within certain statutory limits; and distribute to its
shareholders at least 90% of its net income earned during the year.

PERFORMANCE INFORMATION

Performance depends upon such variables as: portfolio quality; average
portfolio maturity; type of instruments in which the portfolio is
invested; changes in interest rates; changes in expenses; and the
relative amount of cash flow. To the extent that financial
institutions and broker/dealers charge fees in connection with
services provided in conjunction with an investment in shares of the
Fund, the performance will be reduced for those shareholders paying
those fees.

YIELD

The yield is calculated based upon the seven days ending on the day of
the calculation, called the "base period." This yield is computed 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.

For the seven-day period ended July 31, 1997, the yields for
Institutional Shares and Institutional Service Shares were 5.35% and
5.10%, respectively.

EFFECTIVE YIELD

The effective yield is calculated by compounding the unannualized base
period return by: adding 1 to the base period return; raising the sum
to the 365/7th power; and subtracting 1 from the result.

For the seven-day period ended July 31, 1997, the effective yields for
Institutional Shares and Institutional Service Shares were 5.50% and
5.23%, respectively.

TOTAL RETURN

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

For the one-year period ended July 31, 1997, and for the period from
June 2, 1995 (date of initial public investment) through July 31,
1997, the average annual total returns were 5.35% and 5.46%,
respectively, for Institutional Shares.

For the one-year period ended July 31, 1997, and for the period from
May 30, 1995 (date of initial public investment) through July 31,
1997, the average annual total returns were 5.09% and 5.20%,
respectively, for Institutional Service Shares.
