(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

                            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
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: 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:

any time at its sole discretion.

ADMINISTRATIVE FEE

Federated Services Company ("FServ"), under the Administrative Services

this voluntary waiver 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 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.      PERFORMANCE COMPARISONS

                            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.

                           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:

                  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.

                            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 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 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.

                  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.      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:

     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

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

     five largest Standard Metropolitan Statistical Areas. If more than one rate
     is offered, the lowest rate is used. Account minimums and compounding
     methods may vary.
   
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 of
economic, financial, and political developments and their effect on the
securities market. Such discussions may take the form of commentary on these
developments by portfolio managers and their views and analysis on how such
developments could affect the funds. In addition, advertising and sales
literature may quote statistics and give general information about the mutual
fund industry, including the growth of the industry, from sources such as the

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.

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 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

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 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:

INVESTMENT ADVISORY FEE AND OTHER TRANSACTIONS WITH AFFILIATES

INVESTMENT ADVISORY FEE

Federated Management, the Fund's investment adviser (the "Adviser"), receives
for its services an annual investment advisory fee equal to 0.20% of the Fund's
average daily net assets. The Adviser may voluntarily choose to waive any
portion of its fee. The Adviser can modify or terminate this voluntary waiver at
any time at its sole discretion.

ADMINISTRATIVE FEE

Federated Services Company ("FServ"), under the Administrative Services
Agreement, provides the Fund with administrative personnel and services. The fee

this voluntary waiver at any time at its sole discretion.

TRANSFER AND DIVIDEND DISBURSING AGENT FEES AND EXPENSES

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

PORTFOLIO ACCOUNTING FEES

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.

APPENDIX

STANDARD & POOR'S RATINGS GROUP SHORT-TERM MUNICIPAL OBLIGATION RATINGS

A-- Standard & Poor's Ratings Group (S&P) note rating reflects the liquidity
concerns and market access risks unique to notes.

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

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

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

S&P assigns dual ratings to all long-term debt issues that have as part of their
provisions a variable rate demand feature. The first 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.

(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 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.

                            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.

(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 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 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.

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 a portion of the shareholder services fee. The shareholder service
provider can terminate this voluntary waiver at any time at its sole discretion.

(3) The total operating expenses would have been 0.55% absent the voluntary
waivers of portions 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 Capital 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.

                            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.

                       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.

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.      PERFORMANCE

(See Notes which are an integral part of the Financial Statements)

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.

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.

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 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 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.

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.

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.      MONEY MARKET OBLIGATIONS TRUST MANAGEMENT     Officers

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.

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 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 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:

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.

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.

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 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

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:

INVESTMENT ADVISORY FEE AND OTHER TRANSACTIONS WITH AFFILIATES

INVESTMENT ADVISORY FEE

Federated Administrative Services, the Fund's investment adviser (the
"Adviser"), receives for its services an annual investment advisory fee equal to
0.20% of the Fund's average daily net assets. The Adviser may voluntarily choose
to waive any portion of its fee. The Adviser can modify or terminate this
voluntary waiver at any time at its sole discretion.

ADMINISTRATIVE FEE

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

SHAREHOLDER SERVICES FEE

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

TRANSFER AND DIVIDEND DISBURSING AGENT FEES AND EXPENSES

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

PORTFOLIO ACCOUNTING FEES

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

ORGANIZATIONAL EXPENSES

Organizational expenses of $26,061 were borne initially by the Adviser. The Fund
has agreed to reimburse the Adviser for the organizational expenses during the
five-year period following effective date. For the period ended July 31, 1997,
the Fund paid $3,764 pursuant to this agreement.

GENERAL

Certain of the Officers and Trustees of the Trust are Officers and Directors or

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.      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.
   * Salomon 30-Day Treasury Bill Index is a weekly quote of the most
     representative yields for selected securities, issued by the U.S.
     Treasury, maturing in 30 days.
   * Discount Corporation of New York 30-Day Federal Agencies is a weekly quote
     of the average daily offering price for selected federal agency issues
     maturing in 30 days.

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

                                 Cash II Shares



              The following provisions are hereby incorporated and made part of
         the Distributor's Contract dated March 1, 1994, between Money Market
         Obligations Trust and Federated Securities Corp. with respect to the

     1.    The TrustError! Reference source not found.=business trust "Trust"
           "Corporation" hereby appoints FSC to engage in activities principally
           intended to result in the sale of shares of the above-listed Classes
           ("Shares"). Pursuant to this appointment, FSC is authorized to select
           a group of financial institutions ("Financial Institutions") to sell
           Shares at the current offering price thereof as described and set
           forth in the respective prospectuses of the TrustError! Reference
           source not found.=business trust "Trust" "Corporation" .

     2.    During the term of this Agreement, the TrustError! Reference source
           not found.=business trust "Trust" "Corporation" will pay FSC for
           services pursuant to this Agreement, a monthly fee computed at the
           annual rate of 0.25% of the average aggregate net asset value of the
           Shares held during the month. For the month in which this Agreement
           becomes effective or terminates, there shall be an appropriate
           proration of any fee payable on the basis of the number of days that
           the Agreement is in effect during the month.

     3.    FSC may from time-to-time and for such periods as it deems
           appropriate reduce its compensation to the extent any Class' expenses
           exceed such lower expense limitation as FSC may, by notice to the
           TrustError! Reference source not found.=business trust "Trust"
           "Corporation" , voluntarily declare to be effective.

     4.    FSC will enter into separate written agreements with various firms to
           provide certain of the services set forth in Paragraph 1 herein. FSC,
           in its sole discretion, may pay Financial Institutions a periodic fee
           in respect of Shares owned from time to time by their clients or
           customers. The schedules of such fees and the basis upon which such
           fees will be paid shall be determined from time to time by FSC in its
           sole discretion.

     5.   FSC will  prepare  reports  to the Board of  TrusteesError!  Reference
          source  not  found.=business  trust  "Trustees"   "Directors"  of  the
          TrustError!   Reference  source  not  found.=business   trust  "Trust"
          "Corporation" on a quarterly basis showing amounts expended  hereunder
          including  amounts paid to Financial  Institutions and the purpose for
          such expenditures.

              In consideration of the mutual covenants set forth in the
