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 Trustees have
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 financial institutions,
financial intermediaries, and institutional investors as a convenient means of
accumulating an interest in a professionally managed, diversified portfolio
investing 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 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 thirteen 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 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; and

       notes, bonds, and discount notes of U.S. government agencies or
       instrumentalities, such as the: Farm Credit System, including the
       National Bank for Cooperatives, Farm Credit Banks, and Banks for
       Cooperatives; Farmers Home Administration; Federal Home Loan Banks;
       Federal Home Loan Mortgage Corporation; Federal National Mortgage
       Association; Government National Mortgage Association; and Student Loan
       Marketing Association.

Some obligations issued or guaranteed by agencies or instrumentalities of the
U.S. government, such as Government National Mortgage Association participation
certificates, 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.
Accordingly, the Fund may pay more or less than the market value of the
securities on the settlement date.

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 its total assets to secure such borrowings.

   
The above investment limitation 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 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.

REGULATORY COMPLIANCE

   
The Fund may follow non-fundamental operational policies that are more
restrictive than its fundamental investment limitations, as set forth in this
prospectus and its 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, as amended. 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.
    

TRUST INFORMATION
- --------------------------------------------------------------------------------

MANAGEMENT OF THE TRUST

BOARD OF TRUSTEES.  The Trust is managed by a Board of Trustees. The Trustees
are responsible for managing the 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 .20 of 1% of the Fund's average daily net assets. The adviser has
     undertaken to reimburse the Fund up to the amount of the advisory fee for
     operating expenses in excess of limitations established by certain states.
     The adviser also 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.

     more than 250 funds under management and/or administration by its
     subsidiaries, as of December 31, 1995, Federated Investors is one of the
     largest mutual fund investment managers in the United States. With more
     than 1,800 employees, Federated continues to be led by the management who
     founded the company in 1955. Federated funds are presently at work in and
     through 4,000 financial institutions nationwide. More than 100,000
     investment professionals have selected Federated funds for their clients.
    

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 interest. Among other things, the codes: require preclearance and
periodic reporting of personal securities transactions; prohibit personal
transactions in securities being purchased or sold, or being considered for
purchase or sale, by the Fund; prohibit purchasing securities in initial public
offerings; and prohibit taking profits on securities held for less than sixty
days. Violations of the codes are subject to review by the Trustees, and could
result in severe penalties.

DISTRIBUTION OF 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.

   
State securities laws may require certain financial institutions such as
depository institutions to register as dealers.
    

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 .25 of 1% of the average
daily net asset value of the Institutional Shares, computed at an annual rate,
to obtain personal services for shareholders and provide maintenance of
shareholder accounts ("shareholder services"). 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 based upon shares owned by their
clients or customers. 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.
    

ADMINISTRATION OF THE FUND

ADMINISTRATIVE SERVICES.  Federated Administrative Services, a subsidiary of
Federated Investors, provides administrative personnel and services (including
certain legal and financial reporting services) necessary to operate the Fund.
Federated Administrative Services provides these at an annual rate as specified

<TABLE>
<CAPTION>
   MAXIMUM FEE         AVERAGE AGGREGATE DAILY NET ASSETS
<S>                <C>
    .15 of 1%                       on the first $250 million
   .125 of 1%                        on the next $250 million
    .10 of 1%                        on the next $250 million

</TABLE>


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. Average
aggregate daily net assets include those of all mutual funds advised by
affiliates of Federated Investors. Federated Administrative Services may choose
voluntarily to waive a portion of its fee.

CUSTODIAN.  State Street Bank and Trust Company, Boston, MA, is custodian for
the securities and cash of the Fund.

TRANSFER AGENT AND DIVIDEND DISBURSING AGENT.  Federated Services Company,
Boston, MA, is transfer agent for the shares of, and dividend disbursing agent
for, the Fund. Federated Services Company is a subsidiary of Federated
Investors.

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

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 shares from
the value of Fund assets attributable to shares, and dividing the remainder by
the number of 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, Presidents'
Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day,
and Christmas Day.

INVESTING IN THE FUND
- --------------------------------------------------------------------------------

SHARE PURCHASES

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 and the Federal Reserve Wire System are open for business. Shares may
be purchased either by wire or mail. 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.

BY WIRE.  To purchase by Federal Reserve wire, call 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 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.

BY MAIL.  To purchase by mail, send a check made payable to Government
Obligations Fund-- Institutional Shares to: Federated Services Company,
Government Obligations Fund, P.O. Box 8600, Boston, MA 02266-8600. Orders by
mail are considered received when payment by check is converted into federal
funds. This is normally the next business day after the check is received.

MINIMUM INVESTMENT REQUIRED
   
The minimum investment in the Fund is $1,000,000; ordinarily, this will be
achieved by the use of a master account established by the investor. Multiple
master accounts may be maintained by the same investor, but the minimum
investment for each master account will be $1,000,000. The management of the
Fund retains the right to waive the minimum investment requirement for master
acccounts which the management reasonably believes will reach $1,000,000 at some
time within one year of the opening of the account.

CERTIFICATES AND CONFIRMATIONS
    

As transfer agent for the Fund, Federated Services Company maintains a share
account for each shareholder. Share certificates are not issued unless requested
by contacting the Fund or Federated Services Company in writing. Monthly
confirmations are sent to report transactions such as all purchases and
redemptions as well as dividends paid during the month.

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.

REDEEMING SHARES
- --------------------------------------------------------------------------------

Shares are redeemed at their net asset value next determined after Federated
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.

BY MAIL

Shares may be redeemed by sending a written request to: Government Obligations
Fund, Federated Services Company, P.O. Box 8600, Boston, MA 02266-8600. The
written request should state: Government Obligations Fund--Institutional Shares;
shareholder's name; the account number; and the share or dollar amount
requested. Sign the request exactly as the shares are registered. Shareholders
should call the Fund for assistance in redeeming by mail.

If share certificates have been issued, they must be properly endorsed and
should be sent by registered or overnight insured mail with the written request
to Federated Services Company, 500 Victory Road-2nd Floor, North Quincy, MA
02171.

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

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

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

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

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

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

Normally, a check for the proceeds is mailed within one business day, but in no
event more than seven days, after receipt of a proper written redemption
request. Dividends are paid up to and including the day that a redemption
request is processed.

TELEPHONE REDEMPTION

Shares may be redeemed by telephoning the Fund. 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. An
authorization form permitting the Fund to accept telephone requests must first
be completed. Authorization forms and information on this service are available
from Federated Securities Corp.

   
If the redemption request is received before 3:00 p.m. (Eastern time), the
proceeds 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, and those
shares redeemed will not be entitled to that day's dividend. A daily dividend
will be paid on shares redeemed if the redemption request is received after 3:00
p.m. (Eastern time). However, the proceeds are not wired until the following
business day.
    

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

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 mini-mum 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.

SHAREHOLDER INFORMATION
- --------------------------------------------------------------------------------

VOTING RIGHTS

Each share of the Trust gives the shareholder one vote in Trustee elections and
other matters submitted to shareholders for vote. All shares of all classes of
each portfolio in the Trust have equal voting rights, except that in matters
affecting only a particular portfolio or class, only shares of that portfolio or
class are entitled to vote. As a Massachusetts business trust, the Trust is not
required to hold annual shareholder meetings. Shareholder approval will be
sought only for certain changes in the Trust's or the Fund's operation and for
the election of Trustees under certain circumstances. As of September 6, 1995,
Putnam Trust Company, Greenwich, CT, owned approximately 118,529,400 shares
(34.82%) of the voting securities of the Fund's Institutional Service Shares
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.

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

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.

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.

PENNSYLVANIA CORPORATE AND PERSONAL PROPERTY TAXES

In the opinion of Houston, Houston, & Donnelly, 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.

OTHER STATE AND LOCAL TAXES.  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 another class of shares called Institutional Service
Shares. Institutional Service Shares are sold at net asset value primarily to
accounts for which financial institutions act in an agency or fiduciary
capacity, 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 fees 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 1-800-235-4669.

PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------

From time to time, the Fund advertises its yield and effective yield for shares.
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.

Advertisements and sales literature may also refer to total return. 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.

GOVERNMENT OBLIGATIONS FUND
NOTES TO FINANCIAL STATEMENTS
JULY 31, 1995
- --------------------------------------------------------------------------------

(1) 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 diversified 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
Fund offers two classes of shares: Institutional Shares and Institutional
Service Shares.

(2) 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's use of the amortized cost method to value
     its portfolio securities is 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.

     OTHER--Investment transactions are accounted for on the trade date.

(3) SHARES OF BENEFICIAL INTEREST

full and fractional shares of beneficial interest (without par value) for each

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, 1995, 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 our 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, 1995, 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, 1995, the results of its operations for the year then
ended, the changes in its net assets for each of the two years in the period
then ended, and the financial highlights for the periods presented, in
conformity with generally accepted accounting principles.

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 Trustees have
established two classes of shares known as Institutional Shares and
Institutional Service 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,
diversified portfolio investing 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 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 thirteen 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 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; and

       notes, bonds, and discount notes of U.S. government agencies or
       instrumentalities, such as the: Farm Credit System, including the
       National Bank for Cooperatives, Farm Credit Banks, and Banks for
       Cooperatives; Farmers Home Administration; Federal Home Loan Banks;
       Federal Home Loan Mortgage Corporation; Federal National Mortgage
       Association; Government National Mortgage Association; and Student Loan
       Marketing Association.

Some obligations issued or guaranteed by agencies or instrumentalities of the
U.S. government, such as Government National Mortgage Association participation
certificates, 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.
Accordingly, the Fund may pay more or less than the market value of the
securities on the settlement date.

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 its total assets to secure such borrowings.

   
The above investment limitation 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 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.

REGULATORY COMPLIANCE

   
The Fund may follow non-fundamental operational policies that are more
restrictive than its fundamental investment limitations, as set forth in this
prospectus and its 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, as amended. 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.
    
TRUST INFORMATION
- --------------------------------------------------------------------------------

MANAGEMENT OF THE TRUST

BOARD OF TRUSTEES.  The Trust is managed by a Board of Trustees. The Trustees
are responsible for managing the 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 .20 of 1% of the Fund's average daily net assets. The adviser has
     undertaken to reimburse the Fund up to the amount of the advisory fee for
     operating expenses in excess of limitations established by certain states.
     The adviser also 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 $80 billion invested across
     more than 250 funds under management and/or administration by its
     subsidiaries, as of December 31, 1995, Federated Investors is one of the
     largest mutual fund investment managers in the United States. With more
     than 1,800 employees, Federated continues to be led by the management who
     founded the company in 1955. Federated funds are presently at work in and
     through 4,000 financial institutions nationwide. More than 100,000
     investment professionals have selected Federated funds for their clients.
    

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 interest. Among other things, the codes: require preclearance and
periodic reporting of personal securities transactions; prohibit personal
transactions in securities being purchased or sold, or being considered for
purchase or sale, by the Fund; prohibit purchasing securities in initial public
offerings; and prohibit taking profits on securities held for less than sixty
days. Violations of the codes are subject to review by the Trustees, and could
result in severe penalties.

DISTRIBUTION OF 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.

   
State securities laws may require certain financial institutions such as
depository institutions to register as dealers.
    

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 .25 of 1% of the average
daily net asset value of the Institutional Service Shares, computed at an annual
rate, to obtain personal services for shareholders and provide maintenance of
shareholder accounts ("shareholder services"). 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 based upon shares owned by their
clients or customers. 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.

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 shares from
the value of Fund assets attributable to shares, and dividing the remainder by
the number of 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, Presidents'
Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day,
and Christmas Day.

INVESTING IN THE FUND
- --------------------------------------------------------------------------------

SHARE PURCHASES

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 and the Federal Reserve Wire System are open for business. Shares may
be purchased either by wire or mail. 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.

BY WIRE.  To purchase by Federal Reserve wire, call 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 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.

BY MAIL.  To purchase by mail, send a check made payable to Government
Obligations Fund-- Institutional Service Shares to: Federated Services Company,
Government Obligations Fund, P.O. Box 8600, Boston, MA 02266-8600. Orders by
mail are considered received when payment by check is converted into federal
funds. This is normally the next business day after the check is received.

MINIMUM INVESTMENT REQUIRED
   
The minimum investment in the Fund is $1,000,000; ordinarily, this will be
achieved by the use of a master account established by the investor. Multiple
master accounts may be maintained by the same investor, but the minimum
investment for each master account will be $1,000,000. The management of the
Fund retains the right to waive the minimum investment requirement for master
accounts which the management reasonably believes will reach $1,000,000 at some
time within one year of the opening of the account.
    

CERTIFICATES AND CONFIRMATIONS

As transfer agent for the Fund, Federated Services Company maintains a share
account for each shareholder. Share certificates are not issued unless requested
by contacting the Fund or Federated Services Company in writing.

Monthly confirmations are sent to report transactions such as all purchases and
redemptions as well as dividends paid during the month.

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.

REDEEMING SHARES
- --------------------------------------------------------------------------------

Shares are redeemed at their net asset value next determined after Federated
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.

BY MAIL

Shares may be redeemed by sending a written request to: Government Obligations
Fund, Federated Services Company, P.O. Box 8600, Boston, MA 02266-8600. The
written request should state: Government Obligations Fund--Institutional Service
Shares; shareholder's name; the account number; and the share or dollar amount
requested. Sign the request exactly as the shares are registered. Shareholders
should call the Fund for assistance in redeeming by mail.

If share certificates have been issued, they must be properly endorsed and
should be sent by registered or overnight insured mail with the written request
to Federated Services Company, 500 Victory Road--2nd Floor, North Quincy, MA
02171.

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

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

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

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

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

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

Normally, a check for the proceeds is mailed within one business day, but in no
event more than seven days, after receipt of a proper written redemption
request. Dividends are paid up to and including the day that a redemption
request is processed.

TELEPHONE REDEMPTION

Shares may be redeemed by telephoning the Fund. 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. An
authorization form permitting the Fund to accept telephone requests must first
be completed. Authorization forms and information on this service are available
from Federated Securities Corp.

   
If the redemption request is received before 3:00 p.m. (Eastern time), the
proceeds 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, and those
shares redeemed will not be entitled to that day's dividend. A daily dividend
will be paid on shares redeemed if the redemption request is received after 3:00
p.m. (Eastern time). However, the proceeds are not wired until the following
business day.
    

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

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.

SHAREHOLDER INFORMATION
- --------------------------------------------------------------------------------

VOTING RIGHTS

Each share of the Trust gives the shareholder one vote in Trustee elections and
other matters submitted to shareholders for vote. All shares of all classes of
each portfolio in the Trust have equal voting rights, except that in matters
affecting only a particular portfolio or class, only shares of that portfolio or
class are entitled to vote. As a Massachusetts business trust, the Trust is not
required to hold annual shareholder meetings. Shareholder approval will be
sought only for certain changes in the Trust's or the Fund's operation and for
the election of Trustees under certain circumstances. As of September 6, 1995,
Putnam Trust Company, Greenwich, CT, owned approximately 118,529,400 shares
(34.82%) of the voting securities of the Fund's Institutional Service Shares
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.

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

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.

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.

PENNSYLVANIA CORPORATE AND PERSONAL PROPERTY TAXES

In the opinion of Houston, Houston, & Donnelly, 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.

OTHER STATE AND LOCAL TAXES.  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 another class of shares called Institutional Shares.
Institutional Shares are sold at net asset value primarily to accounts for which
financial institutions act in an agency or fiduciary capacity, 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 Shares are distributed with no 12b-1 fees. Currently,
Institutional Shares are accruing no 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 1-800-235-4669.

PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------

From time to time, the Fund advertises its yield and effective yield for shares.
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.
Advertisements and sales literature may also refer to total return. 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.

GOVERNMENT OBLIGATIONS FUND
NOTES TO FINANCIAL STATEMENTS
JULY 31, 1995
- --------------------------------------------------------------------------------

(1) 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 diversified 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
Fund offers two classes of shares: Institutional Shares and Institutional
Service Shares.

(2) 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's use of the amortized cost method to value
     its portfolio securities is 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.

     OTHER--Investment transactions are accounted for on the trade date.

(3) 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, 1995, capital paid-in aggregated $2,265,621,228.
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, 1995, 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 our 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, 1995, 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, 1995, the results of its operations for the year then
ended, the changes in its net assets for each of the two years in the period
then ended, and the financial highlights for the periods presented, in
conformity with generally accepted accounting principles.

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 Trustees have
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 financial institutions,
financial intermediaries, and institutional investors as a convenient means of
accumulating an interest in a professionally managed, diversified portfolio
investing 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 current income consistent with stability
of principal and liquidity. This investment objective cannot be changed without
shareholder approval. The Fund's investment strategy is intended to enable the
Fund to provide shareholders with dividends that are exempt from state and local
income taxation to the extent permissible by federal and state law. While there
is no assurance that the Fund will achieve its investment objective, it
endeavors to do so by following the investment policies described in this
prospectus.

INVESTMENT POLICIES

The Fund pursues its investment objective by investing only in 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 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; and

       notes, bonds, and discount notes of U.S. government agencies or
       instrumentalities, such as the: Farm Credit System, including the
       National Bank for Cooperatives, Farm Credit Banks, and Banks for
       Cooperatives; Farmers Home Administration; Federal Home Loan Banks;

       Federal Home Loan Mortgage Corporation; Federal National Mortgage
       Association; Government National Mortgage Association; and Student Loan
       Marketing Association.

Some obligations issued or guaranteed by agencies or instrumentalities of the
U.S. government, such as Government National Mortgage Association participation
certificates, 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.
Accordingly, the Fund may pay more or less than the market value of the
securities on the settlement date.

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 limitation 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 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.

REGULATORY COMPLIANCE

   
The Fund may follow non-fundamental operational policies that are more
restrictive than its fundamental investment limitations, as set forth in this
prospectus and its 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, as amended. 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.

TRUST INFORMATION
- --------------------------------------------------------------------------------

MANAGEMENT OF THE TRUST

BOARD OF TRUSTEES.  The Trust is managed by a Board of Trustees. The Trustees
are responsible for managing the 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 .20 of 1% of the Fund's average daily net assets. The adviser has
     undertaken to reimburse the Fund up to the amount of the advisory fee for
     operating expenses in excess of limitations established by certain states.
     The adviser also 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 June 14, 1990, 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 $80
     billion invested across more than 250 funds under management and/or
     administration by its subsidiaries, as of December 31, 1995, Federated
     Investors is one of the largest mutual fund investment managers in the
     United States. With more than 1,800 employees, Federated continues to be
     led by the management who founded the company in 1955. Federated funds are
     presently at work in and through 4,000 financial institutions nationwide.
     More than 100,000 investment professionals have selected Federated funds
     for their clients.
    

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 interest. Among other things, the codes: require preclearance and
periodic reporting of personal securities transactions; prohibit personal
transactions in securities being purchased or sold, or being considered for
purchase or sale, by the Fund; prohibit purchasing securities in initial public
offerings; and prohibit taking profits on securities held for less than sixty
days. Violations of the codes are subject to review by the Trustees, and could
result in severe penalties.

DISTRIBUTION OF 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.

   
State securities laws may require certain financial institutions such as
depository institutions to register as dealers.
    

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 .25 of 1% of the average
daily net asset value of Fund shares, computed at an annual rate, to obtain
certain personal services for shareholders and provide maintenance of
shareholder accounts ("shareholder services"). 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.

ADMINISTRATION OF THE FUND

ADMINISTRATIVE SERVICES.  Federated Administrative Services, a subsidiary of
Federated Investors, provides administrative personnel and services (including
certain legal and financial reporting services) necessary to operate the Fund.
Federated Administrative Services provides these at an annual rate as specified
below:
<TABLE>
<CAPTION>
                              AVERAGE AGGREGATE
   MAXIMUM FEE                 DAILY NET ASSETS
<C>                <S>

    .10 of 1%      on the next $250 million
   .075 of 1%      on assets in excess of $750 million
</TABLE>


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. Average
aggregate daily net assets include those of all mutual funds advised by
affiliates of Federated Investors. Federated Administrative Services may choose
voluntarily to waive a portion of its fee.

CUSTODIAN.  State Street Bank and Trust Company, Boston, MA, is custodian for
the securities and cash of the Fund.

TRANSFER AGENT AND DIVIDEND DISBURSING AGENT.  Federated Services Company,
Boston, MA, is transfer agent for the shares of, and dividend disbursing agent
for, the Fund. Federated Services Company is a subsidiary of Federated
Investors.

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

EXPENSES OF THE FUND AND INSTITUTIONAL SHARES

Holders of shares pay their allocable portion of Fund and Trust expenses.

The Trust expenses for which holders of shares pay their allocable portion
include, but are not limited to: the cost of organizing the Trust and continuing
its existence; registering the Trust with federal and state securities
authorities; Trustees' fees; auditors' fees; the cost of meetings of Trustees;
legal fees of the Trust; association membership dues; and such non-recurring and
extraordinary items as may arise.

The Fund expenses for which holders of shares pay their allocable portion
include, but are not limited to: registering the Fund and shares of the Fund;
investment advisory services; taxes and commissions; custodian fees; insurance
premiums; auditors' fees; and such non-recurring and extraordinary items as may
arise.

At present, no expenses are allocated to Institutional Shares as a class.
However, the Trustees reserve the right to allocate certain expenses to holders
of shares as it deems appropriate ("class expenses"). In any case, class
expenses would be limited to: transfer agent fees as identified by the transfer
agent as attributable to holders of shares; printing and postage expenses
related to preparing and distributing materials such as shareholder reports,
prospectuses and proxies to current shareholders; registration fees paid to the
Securities and Exchange Commission and registration fees paid to state
securities commissions; expenses related to administrative personnel and
services as required to support holders of shares; legal fees relating solely to
shares; and Trustees' fees incurred as a result of issues relating solely to
shares.

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 shares from
the value of Fund assets attributable to shares, and dividing the remainder by
the number of 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 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, Presidents' Day, Good Friday, Memorial Day,
Independence Day, Labor Day, Thanksgiving Day, and Christmas Day.
    
INVESTING IN THE FUND
- --------------------------------------------------------------------------------

SHARE PURCHASES

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 and the Federal Reserve Wire System are open for business. Shares may
be purchased either by wire or mail. 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.

BY WIRE.  To purchase by Federal Reserve wire, call the Fund before 1:00 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 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.

BY MAIL.  To purchase by mail, send a check made payable to Government
Obligations Tax-Managed Fund--Institutional Shares to: Federated Services
Company, Government Obligations Tax-Managed Fund, P.O. Box 8600, Boston, MA
02266-8600. Orders by mail are considered received when payment by check is
converted into federal funds. This is normally the next business day after the
check is received.

MINIMUM INVESTMENT REQUIRED
   
The minimum investment in the Fund is $1,000,000; ordinarily, this will be
achieved by the use of a master account established by the investor. Multiple
master accounts may be maintained by the same investor, but the minimum
investment for each master account will be $1,000,000. The management of the
Fund retains the right to waive the minimum investment requirement for master
accounts which the management reasonably believes will reach $1,000,000 at some
time within one year of the opening of the account.
    

CERTIFICATES AND CONFIRMATIONS

       
As transfer agent for the Fund, Federated Services Company maintains a share
account for each shareholder. Share certificates are not issued unless requested
by contacting the Fund or Federated Services Company in writing.

Monthly confirmations are sent to report transactions such as all purchases and
redemptions as well as dividends paid during the month.

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.

REDEEMING SHARES
- --------------------------------------------------------------------------------

Shares are redeemed at their net asset value next determined after Federated
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.

BY MAIL

Shares may be redeemed by sending a written request to: Government Obligations
Tax-Managed Fund, Federated Services Company, P.O. Box 8600, Boston, MA
02266-8600. The written request should state: Government Obligations Tax-Managed
Fund--Institutional Shares; shareholder's name; the account number; and the
share or dollar amount requested. Sign the request exactly as the shares are
registered. Shareholders should call the Fund for assistance in redeeming by
mail.

If share certificates have been issued, they must be properly endorsed and
should be sent by insured mail with the written request to Federated Services
Company, 500 Victory Road--2nd Floor, North Quincy, MA 02171.

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 trust company or commercial bank whose deposits are insured by the Bank
       Insurance Fund which is administered by the Federal Deposit Insurance
       Corporation ("FDIC");
       a member of the New York, American, Boston, Midwest, or Pacific Stock
       Exchanges;

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

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

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

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

Normally, a check for the proceeds is mailed within one business day, but in no
event more than seven days, after receipt of a proper written redemption
request. Dividends are paid up to and including the day that a redemption
request is processed.

TELEPHONE REDEMPTION

Shares may be redeemed by telephoning the Fund. 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. An
authorization form permitting the Fund to accept telephone requests must first
be completed. Authorization forms and information on this service are available
from Federated Securities Corp.

If the redemption request is received before 1:00 p.m. (Eastern time), the
proceeds 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, and those
shares redeemed will not be entitled to that day's dividend. A daily dividend
will be paid on shares redeemed if the redemption request is received after 1:00
p.m. (Eastern time). However, the proceeds are not wired until the following
business day.

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

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.

SHAREHOLDER INFORMATION
- --------------------------------------------------------------------------------

VOTING RIGHTS

Each share of the Trust gives the shareholder one vote in Trustee elections and
other matters submitted to shareholders for vote. All shares of all classes of
each portfolio in the Trust have equal voting rights, except that in matters
affecting only a particular portfolio or class, only shares of that portfolio or
class are entitled to vote. As a Massachusetts business trust, the Trust is not
required to hold annual shareholder meetings. Shareholder approval will be
sought only for certain changes in the Trust's or the Fund's operation and for
the election of Trustees under certain circumstances. As of September 6, 1995,
Citizens Trust Co., Providence, RI, owned approximately 38,117,429 shares
(84.29%) of the voting securities of the Fund's Institutional Shares; and
Anderson & Co., Philadelphia, PA, owned approximately 76,759,107 shares (100%)
of the voting securities of the Fund's Institutional Service Shares 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.

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

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.

TAX INFORMATION
- --------------------------------------------------------------------------------

FEDERAL INCOME TAX

The Fund will pay no federal income tax because it expects to meet requirements
of the Internal Revenue Code, as amended, 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.

PENNSYLVANIA CORPORATE AND PERSONAL PROPERTY TAXES

In the opinion of Houston, Houston, & Donnelly, 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.

OTHER STATE AND LOCAL TAXES.  To the extent permissible by federal and state
law, the Fund is structured to provide shareholders with income that is exempt
or excluded from taxation at the state and local level. Substantially all
dividends paid to shareholders residing in certain states will be exempt or
excluded from state income tax. Many states, by statute, judicial decision or
administrative action, have taken the position that dividends of a regulated
investment company such as the Fund that are attributable to interest on
obligations of the U.S. Treasury and certain U.S. government agencies and
instrumentalities are the functional equivalent of interest from such
obligations and are, therefore, exempt from state and local income taxes.
Shareholders should be aware of the application of their state and local tax
laws to investments in 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 another class of shares called Institutional Service
Shares. Institutional Service Shares are sold at net asset value primarily to
accounts for which financial institutions act in an agency or fiduciary
capacity, 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 fees, 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 1-800-235-4669.

PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------
From time to time, the Fund advertises its yield, effective yield, and total
return for shares. 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.

Advertisements and sales literature may also refer to total return. 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.

GOVERNMENT OBLIGATIONS TAX-MANAGED FUND
NOTES TO FINANCIAL STATEMENTS
JULY 31, 1995
- --------------------------------------------------------------------------------

(1) 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 diversified portfolios. The financial
statements included herein present 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
Fund offers two classes of shares; Institutional Shares and Institutional
Service Shares.

(2) 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's use of the amortized cost method to value
     its portfolio securities is 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 not to exceed a period of five
     years from the Fund's commencement date.

investment advisory fee equal to .20 of 1% of the Fund's average daily net

this voluntary waiver at any time at its sole discretion.

TRANSFER AGENT AND DIVIDEND DISBURSING AGENT FEES AND EXPENSES--Federated
Services Company ("FServ") serves as transfer and dividend disbursing agent for

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.

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, 1995, the related statement of operations,
the statement of changes in net assets, and the financial highlights for the
period from May 30, 1995 (date of initial public investment) 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 audit.

We conducted our audit 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, 1995, 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
audit provides 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, 1995, the results of its operations, the
changes in its net assets, and the financial highlights for the period from May
30, 1995 (date of initial public investment) 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 Trustees have
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, diversified portfolio
investing 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 current income consistent with stability
of principal and liquidity. This investment objective cannot be changed without
shareholder approval. The Fund's investment strategy is intended to enable the
Fund to provide shareholders with dividends that are exempt from state and local
income taxation to the extent permissible by federal and state law. While there
is no assurance that the Fund will achieve its investment objective, it
endeavors to do so by following the investment policies described in this
prospectus.

INVESTMENT POLICIES

The Fund pursues its investment objective by investing only in 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 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; and

       notes, bonds, and discount notes of U.S. government agencies or
       instrumentalities, such as the: Farm Credit System, including the
       National Bank for Cooperatives, Farm Credit Banks, and Banks for
       Cooperatives; Farmers Home Administration; Federal Home Loan Banks;

       Federal Home Loan Mortgage Corporation; Federal National Mortgage
       Association; Government National Mortgage Association; and Student Loan
       Marketing Association.

Some obligations issued or guaranteed by agencies or instrumentalities of the
U.S. government, such as Government National Mortgage Association participation
certificates, 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.
Accordingly, the Fund may pay more or less than the market value of the
securities on the settlement date.

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 limitation 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 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.

REGULATORY COMPLIANCE

   
The Fund may follow non-fundamental operational policies that are more
restrictive than its fundamental investment limitations, as set forth in this
prospectus and its 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, as amended. 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.

TRUST INFORMATION
- --------------------------------------------------------------------------------
MANAGEMENT OF THE TRUST

BOARD OF TRUSTEES.  The Trust is managed by a Board of Trustees. The Trustees
are responsible for managing the 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 .20 of 1% of the Fund's average daily net assets. The adviser has
     undertaken to reimburse the Fund up to the amount of the advisory fee for
     operating expenses in excess of limitations established by certain states.
     The adviser also 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 June 14, 1990, 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 $80
     billion invested across more than 250 funds under management and/or
     administration by its subsidiaries, as of December 31, 1995, Federated
     Investors is one of the largest mutual fund investment managers in the
     United States. With more than 1,800 employees, Federated continues to be
     led by the management who founded the company in 1955. Federated funds are
     presently at work in and through 4,000 financial institutions nationwide.
     More than 100,000 investment professionals have selected Federated funds
     for their clients.
    

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 interest. Among other things, the codes: require preclearance and
periodic reporting of personal securities transactions; prohibit personal
transactions in securities being purchased or sold, or being considered for
purchase or sale, by the Fund; prohibit purchasing securities in initial public
offerings; and prohibit taking profits on securities held for less than sixty
days. Violations of the codes are subject to review by the Trustees, and could
result in severe penalties.

DISTRIBUTION OF 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.

   
State securities laws may require certain financial institutions such as
depository institutions to register as dealers.
    

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 .25 of 1% of the average
daily net asset value of Fund shares, computed at an annual rate, to obtain
certain personal services for shareholders and provide maintenance of
shareholder accounts ("shareholder services"). 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.

ADMINISTRATION OF THE FUND

ADMINISTRATIVE SERVICES.  Federated Administrative Services, a subsidiary of
Federated Investors, provides administrative personnel and services (including
certain legal and financial reporting services) necessary to operate the Fund.
Federated Administrative Services provides these at an annual rate as specified
below:
<TABLE>
<CAPTION>
                              AVERAGE AGGREGATE
   MAXIMUM FEE                 DAILY NET ASSETS
<C>                <S>
    .15 of 1%      on the first $250 million
   .125 of 1%      on the next $250 million
    .10 of 1%      on the next $250 million
   .075 of 1%      on assets in excess of $750 million
</TABLE>


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. Average
aggregate daily net assets include those of all mutual funds advised by
affiliates of Federated Investors. Federated Administrative Services may choose
voluntarily to waive a portion of its fee.

CUSTODIAN.  State Street Bank and Trust Company, Boston, MA, is custodian for
the securities and cash of the Fund.

TRANSFER AGENT AND DIVIDEND DISBURSING AGENT.  Federated Services Company,
Boston, MA, is transfer agent for the shares of, and dividend disbursing agent
for, the Fund. Federated Services Company is a subsidiary of Federated
Investors.

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

EXPENSES OF THE FUND AND INSTITUTIONAL SERVICE SHARES

Holders of shares pay their allocable portion of Fund and Trust expenses.

The Trust expenses for which holders of shares pay their allocable portion
include, but are not limited to: the cost of organizing the Trust and continuing
its existence; registering the Trust with federal and state securities
authorities; Trustees' fees; auditors' fees; the cost of meetings of Trustees;
legal fees of the Trust; association membership dues; and such non-recurring and
extraordinary items as may arise.

The Fund expenses for which holders of shares pay their allocable portion
include, but are not limited to: registering the Fund and shares of the Fund;
investment advisory services; taxes and commissions; custodian fees; insurance
premiums; auditors' fees; and such non-recurring and extraordinary items as may
arise.

At present, the only expenses which are allocated specifically to Institutional
Service Shares as a class are shareholder services fees. However, the Trustees
reserve the right to allocate certain other expenses to holders of shares as it
deems appropriate ("class expenses"). In any case, class expenses would be
limited to: transfer agent fees as identified by the transfer agent as
attributable to holders of shares; printing and postage expenses related to
preparing and distributing materials such as shareholder reports, prospectuses
and proxies to current shareholders; registration fees paid to the Securities
and Exchange Commission and registration fees paid to state securities
commissions; expenses related to administrative personnel and services as
required to support holders of shares; legal fees relating solely to shares; and
Trustees' fees incurred as a result of issues relating solely to shares.

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 shares from
the value of Fund assets attributable to shares, and dividing the remainder by
the number of 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 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, Presidents' Day, Good Friday, Memorial Day,
Independence Day, Labor Day, Thanksgiving Day, and Christmas Day.
    
INVESTING IN THE FUND
- --------------------------------------------------------------------------------

SHARE PURCHASES

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 and the Federal Reserve Wire System are open for business. Shares may
be purchased either by wire or mail. 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.

BY WIRE.  To purchase by Federal Reserve wire, call the Fund before 1:00 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 Services Company, c/o
State Street Bank and Trust Company, Boston, MA; Attention: EDGEWIRE; For Credit
to: Government Obligations Tax-Managed Fund--Institutional Service Shares; Fund
Number (this number can be found on the account statement or by contacting the
Fund); Group Number or Order Number; Nominee or Institution Name; and ABA Number
011000028.

BY MAIL.  To purchase by mail, send a check made payable to Government
Obligations Tax-Managed Fund--Institutional Service Shares to: Federated
Services Company, Government Obligations Tax-Managed Fund, P.O. Box 8600,
Boston, MA 02266-8600. Orders by mail are considered received when payment by
check is converted into federal funds. This is normally the next business day
after the check is received.

MINIMUM INVESTMENT REQUIRED
   
The minimum investment in the Fund is $1,000,000; ordinarily, this will be
achieved by the use of a master account established by the investor. Multiple
master accounts may be maintained by the same investor, but the minimum
investment for each master account will be $1,000,000. The management of the
Fund retains the right to waive the minimum investment requirement for master
accounts which the management reasonably believes will reach $1,000,000 at some
time within one year of the opening of the account.
    
        
CERTIFICATES AND CONFIRMATIONS

As transfer agent for the Fund, Federated Services Company maintains a share
account for each shareholder. Share certificates are not issued unless requested
by contacting the Fund or Federated Services Company in writing.

Monthly confirmations are sent to report transactions such as all purchases and
redemptions as well as dividends paid during the month.

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.

REDEEMING SHARES
- --------------------------------------------------------------------------------

Shares are redeemed at their net asset value next determined after Federated
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.

BY MAIL

Shares may be redeemed by sending a written request to: Government Obligations
Tax-Managed Fund, Federated Services Company, P.O. Box 8600, Boston, MA
02266-8600. The written request should state: Government Obligations Tax-Managed
Fund--Institutional Service Shares; shareholder's name; the account number; and
the share or dollar amount requested. Sign the request exactly as the shares are
registered. Shareholders should call the Fund for assistance in redeeming by
mail.

If share certificates have been issued, they must be properly endorsed and
should be sent by insured mail with the written request to Federated Services
Company, 500 Victory Road-2nd Floor, North Quincy, MA 02171.

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

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

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

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

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

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

Normally, a check for the proceeds is mailed within one business day, but in no
event more than seven days, after receipt of a proper written redemption
request. Dividends are paid up to and including the day that a redemption
request is processed.

TELEPHONE REDEMPTION

Shares may be redeemed by telephoning the Fund. 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. An
authorization form permitting the Fund to accept telephone requests must first
be completed. Authorization forms and information on this service are available
from Federated Securities Corp.

If the redemption request is received before 1:00 p.m. (Eastern time), the
proceeds 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, and those
shares redeemed will not be entitled to that day's dividend. A daily dividend
will be paid on shares redeemed if the redemption request is received after 1:00
p.m. (Eastern time). However, the proceeds are not wired until the following
business day.

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

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.

SHAREHOLDER INFORMATION
- --------------------------------------------------------------------------------

VOTING RIGHTS

Each share of the Trust gives the shareholder one vote in Trustee elections and
other matters submitted to shareholders for vote. All shares of all classes of
each portfolio in the Trust have equal voting rights, except that in matters
affecting only a particular portfolio or class, only shares of that portfolio or
class are entitled to vote. As a Massachusetts business trust, the Trust is not
required to hold annual shareholder meetings. Shareholder approval will be
sought only for certain changes in the Trust's or the Fund's operation and for
the election of Trustees under certain circumstances. As of September 6, 1995,
Citizens Trust Co., Providence, RI, owned approximately 38,117,429 shares
(84.29%) of the voting securities of the Fund's Institutional Shares; and
Anderson & Co., Philadelphia, PA, owned approximately 76,759,107 shares (100%)
of the voting securities of the Fund's Institutional Service Shares 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.

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

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.

TAX INFORMATION
- --------------------------------------------------------------------------------

FEDERAL INCOME TAX

The Fund will pay no federal income tax because it expects to meet requirements
of the Internal Revenue Code, as amended, 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.

PENNSYLVANIA CORPORATE AND PERSONAL PROPERTY TAXES

In the opinion of Houston, Houston, & Donnelly, 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.

OTHER STATE AND LOCAL TAXES.  To the extent permissible by federal and state
law, the Fund is structured to provide shareholders with income that is exempt
or excluded from taxation at the state and local level. Substantially all
dividends paid to shareholders residing in certain states will be exempt or
excluded from state income tax. Many states, by statute, judicial decision or
administrative action, have taken the position that dividends of a regulated
investment company such as the Fund that are attributable to interest on
obligations of the U.S. Treasury and certain U.S. government agencies and
instrumentalities are the functional equivalent of interest from such
obligations and are, therefore, exempt from state and local income taxes.
Shareholders should be aware of the application of their state and local tax
laws to investments in 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 another class of shares called Institutional Shares.
Institutional Shares are sold at net asset value primarily to accounts for which
financial institutions act in an agency or fiduciary capacity, 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 Shares are distributed with no 12b-1 fees. Currently,
Institutional Shares are not accruing 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 1-800-235-4669.

PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------

From time to time, the Fund advertises its yield, effective yield, and total
return for shares. 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.

Advertisements and sales literature may also refer to total return. 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.

GOVERNMENT OBLIGATIONS TAX-MANAGED FUND
NOTES TO FINANCIAL STATEMENTS
JULY 31, 1995
- --------------------------------------------------------------------------------

(1) 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 diversified portfolios. The financial
statements included herein present 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
Fund offers two classes of shares; Institutional Shares and Institutional
Service Shares.

(2) 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's use of the amortized cost method to value
     its portfolio securities is 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 not to exceed a period of five
     years from the Fund's commencement date.

     OTHER--Investment transactions are accounted for on the trade date.

this voluntary waiver at any time at its sole discretion.

TRANSFER AGENT AND DIVIDEND DISBURSING AGENT FEES AND EXPENSES--Federated

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, 1995, the related statement of operations,
the statement of changes in net assets, and the financial highlights for the
period from May 30, 1995 (date of initial public investment) 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 audit.

We conducted our audit 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, 1995, 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
audit provides 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, 1995, the results of its operations, the
changes in its net assets, and the financial highlights for the period from May
30, 1995 (date of initial public investment) 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 Trustees have
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 financial institutions,
financial intermediaries, and institutional investors as a convenient means of
accumulating an interest in a professionally managed, diversified portfolio
investing primarily in short-term money market 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 following the investment policies
described in this prospectus.

INVESTMENT POLICIES

The Fund pursues its investment objective by investing primarily 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, 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.

   
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"), D-1 (+ or -) by Duff & Phelps, 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."
    

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. 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 treat credit-enhanced securities as having been issued by the credit
enhancer for diversification purposes. However, under many circumstances
applicable regulations may require the Fund to treat the securities as having
been issued by both the issuer and the credit enhancer. The bankruptcy,
receivership, or default of the credit enhancer will adversely affect the
quality and marketability of the underlying security.
    

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.
Accordingly, the Fund may pay more or less than the market value of the
securities on the settlement date.

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. Restricted securities are any securities in which the Fund may
otherwise invest pursuant to its investment objective and policies but which are
subject to restrictions on resale under federal securities law. However, the
Fund will limit investments in illiquid securities, including certain restricted
securities not determined by the Trustees to be liquid, non-negotiable time
deposits, and repurchase agreements providing for settlement in more than seven
days after notice, to 10% of its net assets.

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. 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.

CONCENTRATION OF INVESTMENTS.  The Fund may 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. Concentrating investments in any one industry may subject the Fund
to more risk than if it did not concentrate investments.

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 and loan
having capital, surplus, and undivided profits in excess of $100,000,000 at the
time of investment.

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 assets to secure such
borrowings. This investment limitation 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.
    

REGULATORY COMPLIANCE

   
The Fund may follow non-fundamental operational policies that are more
restrictive than its fundamental investment limitations, as set forth in this
prospectus and its 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, as amended. 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 will also 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.
    

TRUST INFORMATION
- --------------------------------------------------------------------------------

MANAGEMENT OF THE TRUST

BOARD OF TRUSTEES.  The Trust is managed by a Board of Trustees. The Trustees
are responsible for managing the 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 .20 of 1% of the Fund's average daily net assets. The adviser has
     undertaken to reimburse the Fund up to the amount of the advisory fee for
     operating expenses in excess of limitations established by certain states.
     The adviser also 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 $80 billion invested across
     more than 250 funds under management and/or administration by its
     subsidiaries, as of December 31, 1995, Federated Investors is one of the
     largest mutual fund investment managers in the United States. With more
     than 1,800 employees, Federated continues to be led by the management who
     founded the company in 1955. Federated funds are presently at work in and
     through 4,000 financial institutions nationwide. More than 100,000
     investment professionals have selected Federated funds for their clients.
    

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 interest. Among other things, the codes: require preclearance and
periodic reporting of personal securities transactions; prohibit personal
transactions in securities being purchased or sold, or being considered for
purchase or sale, by the Fund; prohibit purchasing securities in initial public
offerings; and prohibit taking profits on securities held for less than sixty
days. Violations of the codes are subject to review by the Trustees, and could
result in severe penalties.

DISTRIBUTION OF 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.

   
State securities laws may require certain financial institutions such as
depository institutions to register as dealers.
    

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 .25 of 1% of the average
daily net asset value of the Institutional Shares, computed at an annual rate,
to obtain personal services for shareholders and provide maintenance of
shareholder accounts ("shareholder services"). 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 based upon shares owned by their
clients or customers. 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.
    

ADMINISTRATION OF THE FUND

ADMINISTRATIVE SERVICES.  Federated Administrative Services, a subsidiary of
Federated Investors, provides administrative personnel and services (including
certain legal and financial reporting services) necessary to operate the Fund.
Federated Administrative Services provides these at an annual rate as specified
below:
<TABLE>
<CAPTION>
   MAXIMUM FEE         AVERAGE AGGREGATE DAILY NET ASSETS
<C>                <S>
    .15 of 1%                       on the first $250 million
   .125 of 1%                        on the next $250 million
    .10 of 1%                        on the next $250 million
   .075 of 1%             on assets in excess of $750 million
</TABLE>


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. Average
aggregate daily net assets include those of all mutual funds advised by
affiliates of Federated Investors. Federated Administrative Services may choose
voluntarily to waive a portion of its fee.

CUSTODIAN.  State Street Bank and Trust Company, Boston, MA, is custodian for
the securities and cash of the Fund.

TRANSFER AGENT AND DIVIDEND DISBURSING AGENT.  Federated Services Company,
Boston, MA, is transfer agent for the shares of, and dividend disbursing agent
for, the Fund. Federated Services Company is a subsidiary of Federated
Investors.

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

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 shares from
the value of Fund assets attributable to shares, and dividing the remainder by
the number of 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, Presidents'
Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day,
and Christmas Day.

INVESTING IN THE FUND
- --------------------------------------------------------------------------------

SHARE PURCHASES

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 and the Federal Reserve Wire System are open for business. Shares may
be purchased either by wire or mail. 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.

   
BY WIRE.  To purchase by Federal Reserve wire, call 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 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. The Fund reserves
the right to wire redemption proceeds within seven days of a redemption request
if, in the judgment of the adviser, an earlier payment could adversely affect
the Fund. This procedure may be modified or terminated by the transfer agent or
the Fund.
    

BY MAIL.  To purchase by mail, send a check made payable to Prime Obligations
Fund-Institutional Shares to: Federated Services Company, Prime Obligations
Fund, P.O. Box 8600, Boston, MA 02266-8600. Orders by mail are considered
received when payment by check is converted into federal funds. This is normally
the next business day after the check is received.

MINIMUM INVESTMENT REQUIRED

   
The minimum investment in the Fund is $1,000,000; ordinarily, this will be
achieved by the use of a master account established by the investor. Multiple
master accounts may be maintained by the same investor, but the minimum
investment for each master account will be $1,000,000. The management of the
Fund retains the right to waive the minimum investment requirements for master
acccounts which the management reasonably believes will reach $1,000,000 at some
time within one year of the opening of the account.
    

CERTIFICATES AND CONFIRMATIONS
       
As transfer agent for the Fund, Federated Services Company maintains a share
account for each shareholder. Share certificates are not issued unless requested
by contacting the Fund or Federated Services Company in writing.

Monthly confirmations are sent to report transactions such as all purchases and
redemptions as well as dividends paid during the month.

DIVIDENDS

   
Dividends are declared daily and paid monthly. The amount of dividends declared
by the Fund is based on estimates of net interest income for the Fund. Actual
income may differ from estimates; these differences, if any, will be included in
the calculation of subsequent dividends. 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.

REDEEMING SHARES
- --------------------------------------------------------------------------------

Shares are redeemed at their net asset value next determined after Federated
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.

BY MAIL

Shares may be redeemed by sending a written request to: Prime Obligations Fund,
Federated Services Company, P.O. Box 8600, Boston, MA 02266-8600. The written
request should state: Prime Obligations Fund-Institutional Shares; shareholder's
name; the account number; and the share or dollar amount requested. Sign the
request exactly as the shares are registered. Shareholders should call the Fund
for assistance in redeeming by mail.

If share certificates have been issued, they must be properly endorsed and
should be sent by registered or overnight insured mail with the written request
to Federated Services Company, 500 Victory Road-2nd Floor, North Quincy, MA
02171.

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

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

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

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

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

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

Normally, a check for the proceeds is mailed within one business day, but in no
event more than seven days, after receipt of a proper written redemption
request. Dividends are paid up to and including the day that a redemption
request is processed.

TELEPHONE REDEMPTION

Shares may be redeemed by telephoning the Fund. 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. An
authorization form permitting the Fund to accept telephone requests must first
be completed. Authorization forms and information on this service are available
from Federated Securities Corp.

   
If the redemption request is received before 5:00 p.m. (Eastern time), the
proceeds 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, and those
shares redeemed will not be entitled to that day's dividend. A daily dividend
will be paid on shares redeemed if the redemption request is received after 5:00
p.m. (Eastern time). However, the proceeds are not wired until the following
business day. The Fund reserves the right to wire redemption proceeds within
seven days of a redemption request if, in the judgment of the adviser, an
earlier payment could adversely affect the Fund. This procedure may be modified
or terminated by the transfer agent or the Fund.
    

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

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.

SHAREHOLDER INFORMATION
- --------------------------------------------------------------------------------

VOTING RIGHTS

Each share of the Trust gives the shareholder one vote in Trustee elections and
other matters submitted to shareholders for vote. All shares of all classes of
each portfolio in the Trust have equal voting rights, except that in matters
affecting only a particular portfolio or class, only shares of that portfolio or
class are entitled to vote. As a Massachusetts business trust, the Trust is not
required to hold annual shareholder meetings. Shareholder approval will be
sought only for certain changes in the Trust's or the Fund's operation and for
the election of Trustees under certain circumstances. As of September 6, 1995,
Peoples Bank, Bridgeport, CT, owned approximately 149,257,858 shares (36.34%) of
the voting securities of the Fund's Institutional Service Shares 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.

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

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.

TAX INFORMATION
- --------------------------------------------------------------------------------

FEDERAL INCOME TAX

The Fund will pay no federal income tax because it expects to meet requirements
of the Internal Revenue Code, as amended, 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.

PENNSYLVANIA CORPORATE AND PERSONAL PROPERTY TAXES

In the opinion of Houston, Houston, & Donnelly, 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.

OTHER STATE AND LOCAL TAXES.  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 another class of shares called Institutional Service
Shares. Institutional Service Shares are sold at net asset value primarily to
accounts for which financial institutions act in an agency or fiduciary
capacity, 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 fees 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 1-800-235-4669.

PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------

From time to time, the Fund advertises its yield and effective yield for shares.
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.

Advertisements and sales literature may also refer to total return. 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
NOTES TO FINANCIAL STATEMENTS
JULY 31, 1995
- --------------------------------------------------------------------------------

1. 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, diversified portfolios. The
financial statements presented herein present only those of Prime 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
Fund offers two classes of shares; Institutional Shares and Institutional
Service Shares.

2. 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's use of the amortized cost method to value
     its portfolio securities is 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.

PRIME OBLIGATIONS FUND
- --------------------------------------------------------------------------------

     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.

     OTHER--Investment transactions are accounted for on the trade date.

3. 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, 1995, capital paid-in aggregated $2,958,751,318.

Transactions in shares were as follows:

4. 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 .20 of 1% of the Fund's average daily net assets. The Adviser may
voluntarily choose to waive a portion of its fee. The Adviser can modify or
terminate this voluntary waiver at any time at its sole discretion.

ADMINISTRATIVE FEE--Federated Administrative Services ("FAS") under the
Administrative Services Agreement provides the Fund with administrative
personnel and services. The FAS fee 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 .25 of
1% of average daily net assets of the Fund for the period. This fee is to obtain
certain services for shareholders and to maintain shareholder accounts. FSS may
voluntarily choose to waive a portion of this fee. FSS can modify or terminate
this voluntary waiver at any time at its sole discretion.

TRANSFER AGENT AND DIVIDEND DISBURSING AGENT FEES AND EXPENSES--Federated
Services Company ("FServ") serves as transfer and dividend disbursing agent for
the Fund. This fee 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.

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

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, 1995 is as follows:

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
- --------------------------------------------------------------------------------

To the Shareholders and Board of Trustees of
MONEY MARKET OBLIGATIONS 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, 1995, 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, 1995, 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, 1995, the results of its operations for the year then ended, the
changes in its net assets for each of the two years in the period then ended,
and the financial highlights for the periods presented, in conformity with
generally accepted accounting principles.

                                                             ARTHUR ANDERSEN LLP

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 Trustees have
established two classes of shares known as Institutional Shares and
Institutional Service 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,
diversified portfolio primarily investing in short-term money market 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 following the investment policies
described in this prospectus.

INVESTMENT POLICIES

The Fund pursues its investment objective by investing primarily 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, 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.

   
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"), D-1 (+ or -) by Duffs, 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."
    

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. 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 treat credit-enhanced securities as having been issued by the credit
enhancer for diversification purposes. However, under many circumstances
applicable regulations may require the Fund to treat the securities as having
been issued by both the issuer and the credit enhancer. The bankruptcy,
receivership, or default of the credit enhancer will adversely affect the
quality and marketability of the underlying security.
    

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.
Accordingly, the Fund may pay more or less than the market value of the
securities on the settlement date.

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. Restricted securities are any securities in which the Fund may
otherwise invest pursuant to its investment objective and policies but which are
subject to restrictions on resale under federal securities law. However, the
Fund will limit investments in illiquid securities, including certain restricted
securities not determined by the Trustees to be liquid, non-negotiable time
deposits, and repurchase agreements providing for settlement in more than seven
days after notice, to 10% of its net assets.

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. 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.

CONCENTRATION OF INVESTMENTS.  The Fund may 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. Concentrating investments in any one industry may subject the Fund
to more risk than if it did not concentrate investments.

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 and loan
having capital, surplus, and undivided profits in excess of $100,000,000 at the
time of investment.

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 assets to secure such
borrowings. This investment limitation 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.
    

REGULATORY COMPLIANCE

   
The Fund may follow non-fundamental operational policies that are more
restrictive than its fundamental investment limitations, as set forth in this
prospectus and its 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, as amended. 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 will also 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.
    

TRUST INFORMATION
- --------------------------------------------------------------------------------

MANAGEMENT OF THE TRUST

BOARD OF TRUSTEES.  The Trust is managed by a Board of Trustees. The Trustees
are responsible for managing the 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 .20 of 1% of the Fund's average daily net assets. The adviser has
     undertaken to reimburse the Fund up to the amount of the advisory fee for
     operating expenses in excess of limitations established by certain states.
     The adviser also 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

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 interest. Among other things, the codes: require preclearance and
periodic reporting of personal securities transactions; prohibit personal
transactions in securities being purchased or sold, or being considered for
purchase or sale, by the Fund; prohibit purchasing securities in initial public
offerings; and prohibit taking profits on securities held for less than sixty
days. Violations of the codes are subject to review by the Board of Trustees,
and could result in severe penalties.

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 shares from
the value of Fund assets attributable to shares, and dividing the remainder by
the number of 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, Presidents'
Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day,
and Christmas Day.

INVESTING IN THE FUND
- --------------------------------------------------------------------------------

SHARE PURCHASES

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 and the Federal Reserve Wire System are open for business. Shares may
be purchased either by wire or mail. 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.

   
BY WIRE.  To purchase by Federal Reserve wire, call 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 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.
The Fund reserves the right to wire redemption proceeds within seven days of a
redemption request if, in the judgment of the adviser, an earlier payment could
adversely affect the Fund. This procedure may be modified or terminated by the
transfer agent or the Fund.
    

BY MAIL.  To purchase by mail, send a check made payable to Prime Obligations
Fund-Institutional Service Shares to: Federated Services Company, Prime
Obligations Fund, P.O. Box 8600, Boston, MA 02266-8600. Orders by mail are
considered received when payment by check is converted into federal funds. This
is normally the next business day after the check is received.

MINIMUM INVESTMENT REQUIRED

   
The minimum investment in the Fund is $1,000,000; ordinarily, this will be
achieved by the use of a master account established by the investor. Multiple
master accounts may be maintained by the same investor, but the minimum
investment for each master account will be $1,000,000. The management of the
Fund retains the right to waive the minimum investment requirement for master
accounts which the management reasonably believes will reach $1,000,000 at some
time within one year of the opening of the account.
    

CERTIFICATES AND CONFIRMATIONS
       

As transfer agent for the Fund, Federated Services Company maintains a share
account for each shareholder. Share certificates are not issued unless requested
by contacting the Fund or Federated Services Company in writing.

Monthly confirmations are sent to report transactions such as all purchases and
redemptions as well as dividends paid during the month.

DIVIDENDS

   
Dividends are declared daily and paid monthly. The amount of dividends declared
by the Fund is based on estimates of net interest income for the Fund. Actual
income may differ from estimates; these differences, if any, will be included in
the calculation of subsequent dividends. 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.

REDEEMING SHARES
- --------------------------------------------------------------------------------

Shares are redeemed at their net asset value next determined after Federated
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.

BY MAIL

Shares may be redeemed by sending a written request to: Prime Obligations Fund,
Federated Services Company, P.O. Box 8600, Boston, MA 02266-8600. The written
request should state: Prime Obligations Fund-Institutional Service Shares;
shareholder's name; the account number; and the share or dollar amount
requested. Sign the request exactly as the shares are registered. Shareholders
should call the Fund for assistance in redeeming by mail.

If share certificates have been issued, they must be properly endorsed and
should be sent by registered or overnight insured mail with the written request
to Federated Services Company, 500 Victory Road-2nd Floor, North Quincy, MA
02171.

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

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

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

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

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

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

Normally, a check for the proceeds is mailed within one business day, but in no
event more than seven days, after receipt of a proper written redemption
request. Dividends are paid up to and including the day that a redemption
request is processed.
TELEPHONE REDEMPTION

Shares may be redeemed by telephoning the Fund. 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. An
authorization form permitting the Fund to accept telephone requests must first
be completed. Authorization forms and information on this service are available
from Federated Securities Corp.

   
If the redemption request is received before 5:00 p.m. (Eastern time), the
proceeds 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, and those
shares redeemed will not be entitled to that day's dividend. A daily dividend
will be paid on shares redeemed if the redemption request is received after 5:00
p.m. (Eastern time). However, the proceeds are not wired until the following
business day. The Fund reserves the right to wire redemption proceeds within
seven days of a redemption request if, in the judgment of the adviser, an
earlier payment could adversely affect the Fund. This procedure may be modified
or terminated by the transfer agent or the Fund.
    

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

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.

SHAREHOLDER INFORMATION
- --------------------------------------------------------------------------------

VOTING RIGHTS

Each share of the Trust gives the shareholder one vote in Trustee elections and
other matters submitted to shareholders for vote. All shares of all classes of
each portfolio in the Trust have equal voting rights, except that in matters
affecting only a particular portfolio or class, only shares of that portfolio or
class are entitled to vote. As a Massachusetts business trust, the Trust is not
required to hold annual shareholder meetings. Shareholder approval will be
sought only for certain changes in the Trust's or the Fund's operation and for
the election of Trustees under certain circumstances. As of September 6, 1995,
Peoples Bank, Bridgeport, CT, owned approximately 149,257,858 shares (36.34%) of
the voting securities of the Fund's Institutional Service Shares 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.

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

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.

FEDERAL INCOME TAX

The Fund will pay no federal income tax because it expects to meet requirements
of the Internal Revenue Code, as amended, 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.
PENNSYLVANIA CORPORATE AND PERSONAL PROPERTY TAXES

In the opinion of Houston, Houston, & Donnelly, 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.

OTHER STATE AND LOCAL TAXES.  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 another class of shares called Institutional Shares.
Institutional Shares are sold at net asset value primarily to accounts for which
financial institutions act in an agency or fiduciary capacity, 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 Shares are distributed with no 12b-1 fees. Currently,
Institutional Shares are accruing no 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 1-800-235-4669.

PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------

From time to time, the Fund advertises its yield and effective yield for shares.
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.

Advertisements and sales literature may also refer to total return. 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
NOTES TO FINANCIAL STATEMENTS
JULY 31, 1995
- --------------------------------------------------------------------------------

1. 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, diversified portfolios. The
financial statements presented herein present only those of Prime 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
Fund offers two classes of shares; Institutional Shares and Institutional
Service Shares.

2. 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's use of the amortized cost method to value
     its portfolio securities is 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.

PRIME OBLIGATIONS FUND
- --------------------------------------------------------------------------------

     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.

     OTHER--Investment transactions are accounted for on the trade date.

3. SHARES OF BENEFICIAL INTEREST

REPORT OF INDEPENDENT PUBLIC ACCOUNTANTS
- --------------------------------------------------------------------------------

To the Shareholders and Board of Trustees of
MONEY MARKET OBLIGATIONS 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, 1995, 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, 1995, 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, 1995, the results of its operations for the year then ended, the
changes in its net assets for each of the two years in the period then ended,
and the financial highlights for the periods presented, in conformity with
generally accepted accounting principles.

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 the Fund, as of the date of this prospectus, the Trustees have
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 financial institutions,
financial intermediaries, and institutional investors as a convenient means of
accumulating an interest in a professionally managed, diversified portfolio
investing primarily in short-term municipal securities. The Fund may not be a
suitable investment for retirement plans since it invests in municipal
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 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 following the investment policies described in this
prospectus.

INVESTMENT POLICIES

The Fund pursues its investment objective by investing in a portfolio of
municipal securities (as defined below) maturing in 13 months 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.) 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 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 ("TRANs") issued to finance working
       capital needs in anticipation of receiving taxes or other revenues;

       bond anticipation notes ("BANs") 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 and loan 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.

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 FIN-1+ or FIN-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."

Further, the Fund has the ability but no present intention of investing in:
securities that are rated MIG-2 or VMIG-2 by Moody's, SP-2 by S&P, FIN-2 by
Fitch; tax-exempt commercial paper that is rated P-2 by Moody's, A-2 by S&P, or
F-2 by Fitch; and securities that are not rated but are deemed to be of
comparable quality. Shareholders will be notified should the Fund decide to
invest in these securities.

CREDIT ENHANCEMENT.  Certain of the Fund's acceptable investments may be credit
enhanced by a guaranty, letter of credit, or insurance. 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 bankruptcy,
receivership, or default of the credit enhancer will adversely affect the
quality and marketability of the underlying security.

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.
Accordingly, the Fund may pay more or less than the market value of the
securities on the settlement date.

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. 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 laws. Under criteria
established by the Trustees, certain restricted securities are determined to be
liquid. To the extent that restricted securities are not determined to be
liquid, the Fund will limit their purchase, together with other illiquid
securities, to 10% of its total 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 such as: obligations issued
by or on behalf of municipal or corporate issuers having the same quality
characteristics as described above; 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 institution 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.

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 assets to secure such borrowings. This investment limitation
cannot be changed without shareholder approval.

REGULATORY COMPLIANCE

   
The Fund may follow non-fundamental operational policies that are more
restrictive than its fundamental investment limitations, as set forth in this
prospectus and its 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, as amended. 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.
    

TRUST INFORMATION
- --------------------------------------------------------------------------------

MANAGEMENT OF THE TRUST

BOARD OF TRUSTEES.  The Trust is managed by a Board of Trustees. The Trustees
are responsible for managing the 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 .20 of 1% of the Fund's average daily net assets. The adviser has
     undertaken to reimburse the Fund up to the amount of the advisory fee for
     operating expenses in excess of limitations established by certain states.
     The adviser also 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 $80 billion invested across
     more than 250 funds under management and/or administration by its
     subsidiaries, as of December 31, 1995, Federated Investors is one of the
     largest mutual fund investment managers in the United States. With more
     than 1,800 employees, Federated continues to be led by the management who
     founded the company in 1955. Federated funds are presently at work in and
     through 4,000 financial institutions nationwide. More than 100,000
     investment professionals have selected Federated funds for their clients.
    

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 interest. Among other things, the codes: require preclearance and
periodic reporting of personal securities transactions; prohibit personal
transactions in securities being purchased or sold, or being considered for
purchase or sale, by the Fund; prohibit purchasing securities in initial public
offerings; and prohibit taking profits on securities held for less than sixty
days. Violations of the codes are subject to review by the Trustees, and could
result in severe penalties.

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 shares from
the value of Fund assets attributable to shares, and dividing the remainder by
the number of 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, Presidents'
Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day,
and Christmas Day.

(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 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.

BY MAIL.  To purchase by mail, send a check made payable to Tax-Free Obligations
Fund-- Institutional Shares to: Federated Services Company, Tax-Free Obligations
Fund, P.O. Box 8600, Boston, MA 02266-8600. Orders by mail are considered
received when payment by check is converted into federal funds. This is normally
the next business day after the check is received.

   
MINIMUM INVESTMENT REQUIRED

The minimum investment in the Fund is $1,000,000; ordinarily, this will be
achieved by the use of a master account established by the investor. Multiple
master accounts may be maintained by the same investor, but the minimum
investment for each master account will be $1,000,000. The management of the
Fund retains the right to waive the minimum investment requirement for master
accounts which the management reasonably believes will reach $1,000,000 at some
time within one year of the opening of the account.


CERTIFICATES AND CONFIRMATIONS

    

As transfer agent for the Fund, Federated Services Company maintains a share
account for each shareholder. Share certificates are not issued unless requested
by contacting the Fund or Federated Services Company in writing.

Monthly confirmations are sent to report transactions such as all purchases and
redemptions as well as dividends paid during the month.

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.

REDEEMING SHARES
- --------------------------------------------------------------------------------

Shares are redeemed at their net asset value next determined after Federated
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.

BY MAIL

Shares may be redeemed by sending a written request to: Tax-Free Obligations
Fund, Federated Services Company, P.O. Box 8600, Boston, MA 02266-8600. The
written request should state: Tax-Free Obligations Fund--Institutional Shares;
shareholder's name; the account number; and the share or dollar amount
requested. Sign the request exactly as the shares are registered. Shareholders
should call the Fund for assistance in redeeming by mail.

If share certificates have been issued, they must be properly endorsed and
should be sent by registered or overnight insured mail with the written request
to Federated Services Company, 500 Victory Road--2nd Floor, North Quincy, MA
02171.

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

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

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

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

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

The Fund and the transfer agent have adopted standards for accepting signature
guarantees from the above institutions. The Fund may elect in the future to
limit eligible signature guarantors to

institutions that are members of the signature guarantee program. The Fund and
its transfer agent reserve the right to amend these standards at any time
without notice.

Normally, a check for the proceeds is mailed within one business day, but in no
event more than seven days, after receipt of a proper written redemption
request. Dividends are paid up to and including the day that a redemption
request is processed.

TELEPHONE REDEMPTION
- --------------------------------------------------------------------------------

Shares may be redeemed by telephoning the Fund. 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. An
authorization form permitting the Fund to accept telephone requests must first
be completed. Authorization forms and information on this service are available
from Federated Securities Corp.

   
If the redemption request is received before 12:00 noon (Eastern time), the
proceeds 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, and those
shares redeemed will not be entitled to that day's dividend. A daily dividend
will be paid on shares redeemed if the redemption request is received after
12:00 noon (Eastern time). However, the proceeds are not wired until the
following business day.
    

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

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.

SHAREHOLDER INFORMATION
- --------------------------------------------------------------------------------

VOTING RIGHTS

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

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

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.

TAX INFORMATION
- --------------------------------------------------------------------------------

FEDERAL INCOME TAX

The Fund will pay no federal income tax because it expects to meet requirements
of the Internal Revenue Code, as amended, 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 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.

PENNSYLVANIA CORPORATE AND PERSONAL PROPERTY TAXES

In the opinion of Houston, Houston, & Donnelly, 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.

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

OTHER CLASSES OF SHARES
- --------------------------------------------------------------------------------

   
The Fund also offers another class of shares called Institutional Service
Shares. Institutional Service Shares are sold at net asset value primarily to
accounts for which financial institutions act in an agency or fiduciary
capacity, 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 fees 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 1-800-235-4669.

PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------

From time to time, the Fund advertises its yield, effective yield, and
tax-equivalent yield for shares. 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 tax-exempt yield, assuming a specific tax rate.

Advertisements and sales literature may also refer to total return. 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.

TAX-FREE OBLIGATIONS FUND
NOTES TO FINANCIAL STATEMENTS
JULY 31, 1995
- --------------------------------------------------------------------------------

(1) 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 diversified 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 Fund offers
two classes of shares: Institutional Shares and Institutional Service Shares.

(2) 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's use of the amortized cost method to value
     its portfolio securities is 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.

     At July 31, 1995, the Fund, for federal tax purposes, had a capital loss
     carryforward of $19,800, 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:
<TABLE>
<CAPTION>
    EXPIRATION YEAR         EXPIRATION AMOUNT
<S>                      <C>
         2001                        $580
         2002                     $19,220
</TABLE>


     Additionally, net capital losses of $1,435 attributable to security
     transactions incurred after October 31, 1994 are treated as arising on
     August 1, 1995, the first day of the Fund's next taxable year.

TAX-FREE OBLIGATIONS FUND
- --------------------------------------------------------------------------------

     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.

     OTHER--Investment transactions are accounted for on the trade date.

(3) 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, 1995, capital paid-in aggregated $1,547,494,731.
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, 1995, 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, 1995, by correspondence with the custodian and broker. 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, 1995, the results of its operations for the year then
ended, the changes in its net assets for each of the two years in the period
then ended, and the financial highlights for the periods presented, in
conformity with generally accepted accounting principles.

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 the Fund, as of the date of this prospectus, the Trustees have
established two classes of shares known as Institutional Shares and
Institutional Service 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,
diversified portfolio investing primarily in short-term municipal securities.
The Fund may not be a suitable investment for retirement plans since it invests
in municipal 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 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 following the investment policies described in this
prospectus.

INVESTMENT POLICIES

The Fund pursues its investment objective by investing in a portfolio of
municipal securities (as defined below) maturing in 13 months 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.) 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 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 ("TRANs") issued to finance working
       capital needs in anticipation of receiving taxes or other revenues;

       bond anticipation notes ("BANs") 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 and loan 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.

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 FIN-1+ or FIN-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."

Further, the Fund has the ability but no present intention of investing in:
securities that are rated MIG-2 or VMIG-2 by Moody's, SP-2 by S&P, FIN-2 by
Fitch; tax-exempt commercial paper that is rated P-2 by Moody's, A-2 by S&P, or
F-2 by Fitch; and securities that are not rated but are deemed to be of
comparable quality. Shareholders will be notified should the Fund decide to
invest in these securities.

CREDIT ENHANCEMENT.  Certain of the Fund's acceptable investments may be credit
enhanced by a guaranty, letter of credit, or insurance. 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 bankruptcy,
receivership, or default of the credit enhancer will adversely affect the
quality and marketability of the underlying security.

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.
Accordingly, the Fund may pay more or less than the market value of the
securities on the settlement date.

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. 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 laws. Under criteria
established by the Trustees, certain restricted securities are determined to be
liquid. To the extent that restricted securities are not determined to be
liquid, the Fund will limit their purchase, together with other illiquid
securities, to 10% of its total 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 such as: obligations issued
by or on behalf of municipal or corporate issuers having the same quality
characteristics as described above; 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 institution 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.

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 assets to secure such borrowings. This investment limitation
cannot be changed without shareholder approval.

REGULATORY COMPLIANCE

   
The Fund may follow non-fundamental operational policies that are more
restrictive than its fundamental investment limitations, as set forth in this
prospectus and its 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, as amended. 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.
    

TRUST INFORMATION
- --------------------------------------------------------------------------------

MANAGEMENT OF THE TRUST

BOARD OF TRUSTEES.  The Trust is managed by a Board of Trustees. The Trustees
are responsible for managing the 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 .20 of 1% of the Fund's average daily net assets. The adviser has
     undertaken to reimburse the Fund up to the amount of the advisory fee for
     operating expenses in excess of limitations established by certain states.
     The adviser also 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 $80 billion invested across
     more than 250 funds under management and/or administration by its
     subsidiaries, as of December 31, 1995, Federated Investors is one of the
     largest mutual fund investment managers in the United States. With more
     than 1,800 employees, Federated continues to be led by the management who
     founded the company in 1955. Federated funds are presently at work in and
     through 4,000 financial institutions nationwide. More than 100,000
     investment professionals have selected Federated funds for their clients.
    

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 interest. Among other things, the codes: require preclearance and
periodic reporting of personal securities transactions; prohibit personal
transactions in securities being purchased or sold, or being considered for
purchase or sale, by the Fund; prohibit purchasing securities in initial public
offerings; and prohibit taking profits on securities held for less than sixty
days. Violations of the codes are subject to review by the Trustees, and could
result in severe penalties.

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 shares from
the value of Fund assets attributable to shares, and dividing the remainder by
the number of 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, Presidents' Day, Good Friday, Memorial Day,
Independence Day, Labor Day, Thanksgiving Day, and Christmas Day.

INVESTING IN THE FUND
- --------------------------------------------------------------------------------

SHARE PURCHASES

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 and the Federal Reserve Wire System are open for business. Shares may
be purchased either by wire or mail. 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.

BY WIRE.  To purchase by Federal Reserve wire, call 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 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.

BY MAIL.  To purchase by mail, send a check made payable to Tax-Free Obligations
Fund-- Institutional Service Shares to: Federated Services Company, Tax-Free
Obligations Fund, P.O. Box 8600, Boston, MA 02266-8600. Orders by mail are
considered received when payment by check is converted into federal funds. This
is normally the next business day after the check is received.

MINIMUM INVESTMENT REQUIRED

   
The minimum investment in the Fund is $1,000,000; ordinarily, this will be
achieved by the use of a master account established by the investor. Multiple
master accounts may be maintained by the same investor, but the minimum
investment for each master account will be $1,000,000. The management of the
Fund retains the right to waive the minimum investment requirement for master
accounts which the management reasonably believes will reach $1,000,000 at some
time within one year of the opening of the account.


CERTIFICATES AND CONFIRMATIONS
    

As transfer agent for the Fund, Federated Services Company maintains a share
account for each shareholder. Share certificates are not issued unless requested
by contacting the Fund or Federated Services Company in writing.

Monthly confirmations are sent to report transactions such as all purchases and
redemptions as well as dividends paid during the month.

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.

REDEEMING SHARES
- --------------------------------------------------------------------------------

Shares are redeemed at their net asset value next determined after Federated
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.

BY MAIL

Shares may be redeemed by sending a written request to: Tax-Free Obligations
Fund, Federated Services Company, P.O. Box 8600, Boston, MA 02266-8600. The
written request should state: Tax-Free Obligations Fund--Institutional Service
Shares; shareholder's name; the account number; and the share or dollar amount
requested. Sign the request exactly as the shares are registered. Shareholders
should call the Fund for assistance in redeeming by mail.

If share certificates have been issued, they must be properly endorsed and
should be sent by registered or overnight insured mail with the written request
to Federated Services Company, 500 Victory Road--2nd Floor, North Quincy, MA
02171.

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

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

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

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

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

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

Normally, a check for the proceeds is mailed within one business day, but in no
event more than seven days, after receipt of a proper written redemption
request. Dividends are paid up to and including the day that a redemption
request is processed.

TELEPHONE REDEMPTION

Shares may be redeemed by telephoning the Fund. 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. An
authorization form permitting the Fund to accept telephone requests must first
be completed. Authorization forms and information on this service are available
from Federated Securities Corp.
   
If the redemption request is received before 12:00 noon (Eastern time), the
proceeds 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, and those
shares redeemed will not be entitled to that day's dividend. A daily dividend
will be paid on shares redeemed if the redemption request is received after
12:00 noon (Eastern time). However, the proceeds are not wired until the
following business day.
    

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

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.

SHAREHOLDER INFORMATION
- --------------------------------------------------------------------------------

VOTING RIGHTS

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

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

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.
TAX INFORMATION
- --------------------------------------------------------------------------------

FEDERAL INCOME TAX

The Fund will pay no federal income tax because it expects to meet requirements
of the Internal Revenue Code, as amended, 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 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.

PENNSYLVANIA CORPORATE AND PERSONAL PROPERTY TAXES

In the opinion of Houston, Houston, & Donnelly, 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.

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

OTHER CLASSES OF SHARES
- --------------------------------------------------------------------------------

   
The Fund also offers another class of shares called Institutional Shares.
Institutional Shares are sold at net asset value primarily to accounts for which
financial institutions act in an agency or fiduciary capacity, 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 Shares are distributed with no 12b-1 fees. Currently,
Institutional Shares are accruing no 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 1-800-235-4669.

PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------

From time to time, the Fund advertises its yield, effective yield, and
tax-equivalent yield for shares. 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 tax-exempt yield, assuming a specific tax rate.

Advertisements and sales literature may also refer to total return. 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.

TAX-FREE OBLIGATIONS FUND
NOTES TO FINANCIAL STATEMENTS
JULY 31, 1995
- --------------------------------------------------------------------------------

(1) 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 diversified 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 Fund offers
two classes of shares: Institutional Shares and Institutional Service Shares.

(2) 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's use of the amortized cost method to value
     its portfolio securities is 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.

     At July 31, 1995, the Fund, for federal tax purposes, had a capital loss
     carryforward of $19,800, 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:
<TABLE>
<CAPTION>
    EXPIRATION YEAR         EXPIRATION AMOUNT
<S>                      <C>
         2001                        $580
         2002                     $19,220
</TABLE>


     Additionally, net capital losses of $1,435 attributable to security
     transactions incurred after October 31, 1994 are treated as arising on
     August 1, 1995, the first day of the Fund's next taxable year.

TAX-FREE OBLIGATIONS FUND
- --------------------------------------------------------------------------------

     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.

     OTHER--Investment transactions are accounted for on the trade date.

(3) 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, 1995, capital paid-in aggregated $1,547,494,731.
Transactions in shares were as follows:

TRANSFER AGENT AND DIVIDEND DISBURSING AGENT FEES AND EXPENSES--Federated

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, 1995, 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, 1995, by correspondence with the custodian and broker. 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, 1995, the results of its operations for the year then
ended, the changes in its net assets for each of the two years in the period
then ended, and the financial highlights for the periods presented, in
conformity with generally accepted accounting principles.

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 Trustees have
established two classes of shares known as Institutional Service Shares and
Institutional Shares. This prospectus relates only to Institutional 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, diversified portfolio
investing in short-term U.S. Treasury 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

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.
Accordingly, the Fund may pay more or less than the market value of the
securities on the settlement date.

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 assets to secure such borrowings.

The above investment limitation 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.

REGULATORY COMPLIANCE

   
The Fund may follow non-fundamental operational policies that are more
restrictive than its fundamental investment limitations, as set forth in this
prospectus and its 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, as amended. 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.
    

TRUST INFORMATION
- --------------------------------------------------------------------------------

MANAGEMENT OF THE TRUST

BOARD OF TRUSTEES.  The Trust is managed by a Board of Trustees. The Trustees
are responsible for managing the 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 .20 of 1% of the Fund's average daily net assets. The adviser has
     undertaken to reimburse the Fund up to the amount of the advisory fee for
     operating expenses in excess of limitations established by certain states.
     The adviser also 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 $80 billion invested across more than 250 funds
under management and/or administration by its subsidiaries, as of December 31,
1995, Federated Investors is one of the largest mutual fund investment managers
in the United States. With more than 1,800 employees, Federated continues to be
led by the management who founded the company in 1955. Federated funds are
presently at work in and through 4,000 financial institutions nationwide. More
than 100,000 investment professionals have selected Federated funds for their
clients.
    

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 interest. Among other things, the codes: require preclearance and
periodic reporting of personal securities transactions; prohibit personal
transactions in securities being purchased or sold, or being considered for
purchase or sale, by the Fund; prohibit purchasing securities in initial public
offerings; and prohibit taking profits on securities held for less than sixty
days. Violations of the codes are subject to review by the Trustees, and could
result in severe penalties.

DISTRIBUTION OF 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.

   
State securities laws may require certain financial institutions such as
depository institutions to register as dealers.
    
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 .25 of 1% of the average
daily net asset value of the Institutional Shares, computed at an annual rate,
to obtain personal services for shareholders and provide maintenance of
shareholder accounts ("shareholder services"). 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 based upon shares owned by their
clients or customers. 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.
    

ADMINISTRATION OF THE FUND

ADMINISTRATIVE SERVICES.  Federated Administrative Services, a subsidiary of
Federated Investors, provides administrative personnel and services (including
certain legal and financial reporting services) necessary to operate the Fund.
Federated Administrative Services provides these at an annual rate as specified
below:
<TABLE>
<CAPTION>
   MAXIMUM FEE         AVERAGE AGGREGATE DAILY NET ASSETS
   -----------         ----------------------------------
<C>                <S>
    .15 of 1%                       on the first $250 million
   .125 of 1%                        on the next $250 million
    .10 of 1%                        on the next $250 million
   .075 of 1%             on assets in excess of $750 million
</TABLE>


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. Average
aggregate daily net assets include those of all mutual funds advised by
affiliates of Federated Investors. Federated Administrative Services may choose
voluntarily to waive a portion of its fee.

CUSTODIAN.  State Street Bank and Trust Company, Boston, MA, is custodian for
the securities and cash of the Fund.

TRANSFER AGENT AND DIVIDEND DISBURSING AGENT.  Federated Services Company,
Boston, MA, is transfer agent for the shares of, and dividend disbursing agent
for, the Fund. Federated Services Company is a subsidiary of Federated
Investors.

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

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 shares from
the value of Fund assets attributable to shares, and dividing the remainder by
the number of 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, Presidents'
Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day,
and Christmas Day.

INVESTING IN THE FUND
- --------------------------------------------------------------------------------

SHARE PURCHASES

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 and the Federal Reserve Wire System are open for business. Shares may
be purchased either by wire or mail. 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.

   
BY WIRE.  To purchase by Federal Reserve wire, call 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 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. The Fund
reserves the right to wire redemption proceeds within seven days of a redemption
request if, in the judgment of the adviser, an earlier payment could adversely
affect the Fund. This procedure may be modified or terminated by the transfer
agent or the Fund.
    

BY MAIL.  To purchase by mail, send a check made payable to Treasury Obligations
Fund-- Institutional Shares to: Federated Services Company, Treasury Obligations
Fund, P.O. Box 8600, Boston, MA 02266-8600. Orders by mail are considered
received when payment by check is converted into federal funds. This is normally
the next business day after the check is received.

MINIMUM INVESTMENT REQUIRED

   
The minimum investment in the Fund is $1,000,000; ordinarily, this will be
achieved by the use of a master account established by the investor. Multiple
master accounts may be maintained by the same investor, but the minimum
investment for each master account will be $1,000,000. The management of the
Fund retains the right to waive the minimum investment requirements for master
acccounts which the management reasonably believes will reach $1,000,000 at some
time within one year of the opening of the account.
    
        
CERTIFICATES AND CONFIRMATIONS


As transfer agent for the Fund, Federated Services Company maintains a share
account for each shareholder. Share certificates are not issued unless requested
by contacting the Fund or Federated Services Company in writing.

Monthly confirmations are sent to report transactions such as all purchases and
redemptions as well as dividends paid during the month.

DIVIDENDS

   
Dividends are declared daily and paid monthly. The amount of dividends declared
by the Fund is based on estimates of net interest income for the Fund. Actual
income may differ from estimates; these differences, if any, will be included in
the calculation of subsequent dividends. 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.

REDEEMING SHARES
- --------------------------------------------------------------------------------

Shares are redeemed at their net asset value next determined after Federated
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.

BY MAIL

Shares may be redeemed by sending a written request to: Treasury Obligations
Fund, Federated Services Company, P.O. Box 8600, Boston, MA 02266-8600. The
written request should state: Treasury Obligations Fund-Institutional Shares;
shareholder's name; the account number; and the share or dollar amount
requested. Sign the request exactly as the shares are registered. Shareholders
should call the Fund for assistance in redeeming by mail.

If share certificates have been issued, they must be properly endorsed and
should be sent by registered or overnight insured mail with the written request
to Federated Services Company, 500 Victory Road-2nd Floor, North Quincy, MA
02171.

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

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

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

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

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

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

Normally, a check for the proceeds is mailed within one business day, but in no
event more than seven days, after receipt of a proper written redemption
request. Dividends are paid up to and including the day that a redemption
request is processed.
TELEPHONE REDEMPTION

Shares may be redeemed by telephoning the Fund. 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. An
authorization form permitting the Fund to accept telephone requests must first
be completed. Authorization forms and information on this service are available
from Federated Securities Corp.

   
If the redemption request is received before 5:00 p.m. (Eastern time), the
proceeds 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, and those
shares redeemed will not be entitled to that day's dividend. A daily dividend
will be paid on shares redeemed if the redemption request is received after 5:00
p.m. (Eastern time). However, the proceeds are not wired until the following
business day. The Fund reserves the right to wire redemption proceeds within
seven days of a redemption request if, in the judgment of the adviser, an
earlier payment could adversely affect the Fund. This procedure may be modified
or terminated by the transfer agent or the Fund.
    

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

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.

SHAREHOLDER INFORMATION
- --------------------------------------------------------------------------------

VOTING RIGHTS

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

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

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.

TAX INFORMATION
- --------------------------------------------------------------------------------

FEDERAL INCOME TAX

The Fund will pay no federal income tax because it expects to meet requirements
of the Internal Revenue Code, as amended, 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.

PENNSYLVANIA CORPORATE AND PERSONAL PROPERTY TAXES

In the opinion of Houston, Houston, & Donnelly, 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.

OTHER STATE AND LOCAL TAXES.  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 another class of shares called Institutional Service
Shares. Institutional Service Shares are sold at net asset value primarily to
accounts for which financial institutions act in an agency or fiduciary
capacity, 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 fees 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 1-800-235-4669.

PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------

From time to time, the Fund advertises its yield and effective yield for shares.
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.

Advertisements and sales literature may also refer to total return. 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.

     INVESTMENT VALUATIONS--The Fund's use of the amortized cost method to value
     its portfolio securities is 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 investment 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 paid under the repurchase
     agreement transaction.

     The Fund will only enter into repurchase agreements with banks and other
     recognized financial institutions, such as brokers/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.

TREASURY OBLIGATIONS FUND
- --------------------------------------------------------------------------------

     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 not to exceed a period of five
     years from the Fund's commencement date.

     OTHER--Investment transactions are accounted for on the trade date.

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, 1995, 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, 1995, 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, 1995, the results of its operations for the year then
ended, the changes in its net assets for each of the two years in the period
then ended, and the financial highlights for the periods presented, in
conformity with generally accepted accounting principles.

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 Trustees have
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, diversified portfolio
investing in short-term U.S. Treasury 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 following the investment policies
described in this prospectus.

INVESTMENT POLICIES

The Fund pursues its investment objective by investing only in 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, 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.
Accordingly, the Fund may pay more or less than the market value of the
securities on the settlement date.

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 assets to secure such borrowings.

The above investment limitation 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.

REGULATORY COMPLIANCE

   
The Fund may follow non-fundamental operational policies that are more
restrictive than its fundamental investment limitations, as set forth in this
prospectus and its 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, as amended. 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.
    

TRUST INFORMATION
- --------------------------------------------------------------------------------

MANAGEMENT OF THE TRUST
BOARD OF TRUSTEES.  The Trust is managed by a Board of Trustees. The Trustees
are responsible for managing the 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 .20 of 1% of the Fund's average daily net assets. The adviser has
     undertaken to reimburse the Fund up to the amount of the advisory fee for
     operating expenses in excess of limitations established by certain states.
     The adviser also 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 $80 billion invested across
     more than 250 funds under management and/or administration by its
     subsidiaries, as of December 31, 1995, Federated Investors is one of the
     largest mutual fund investment managers in the United States. With more
     than 1800 employees, Federated continues to be led by the management who
     founded the company in 1955. Federated funds are presently at work in and
     through 4,000 financial institutions nationwide. More than 100,000
     investment professionals have selected Federated funds for their clients.
    

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 interest. Among other things, the codes: require preclearance and
periodic reporting of personal securities transactions; prohibit personal
transactions in securities being purchased or sold, or being considered for
purchase or sale, by the Fund; prohibit purchasing securities in initial public
offerings; and prohibit taking profits on securities held for less than sixty
days. Violations of the codes are subject to review by the Trustees, and could
result in severe penalties.

DISTRIBUTION OF 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.

   
State securities laws may require certain financial institutions such as
depository institutions to register as dealers.
    

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 .25 of 1% of the average
daily net asset value of the Institutional Service Shares, computed at an annual
rate, to obtain personal services for shareholders and provide maintenance of
shareholder accounts ("shareholder services"). 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 based upon shares owned by their
clients or customers. 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.
    

ADMINISTRATION OF THE FUND

Federated Investors, provides administrative personnel and services (including
certain legal and financial reporting services) necessary to operate the Fund.

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 shares from
the value of Fund assets attributable to shares, and dividing the remainder by
the number of 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, Presidents'
Day, Good Friday, Memorial Day, Independence Day, Labor Day, Thanksgiving Day,
and Christmas Day.

INVESTING IN THE FUND
- --------------------------------------------------------------------------------

SHARE PURCHASES

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 and the Federal Reserve Wire System are open for business. Shares may
be purchased either by wire or mail. 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.

   
BY WIRE.  To purchase by Federal Reserve wire, call 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 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.
The Fund reserves the right to wire redemption proceeds within seven days of a
redemption request if, in the judgment of the adviser, an earlier payment could
adversely affect the Fund. This procedure may be modified or terminated by the
transfer agent or the Fund.
    

BY MAIL.  To purchase by mail, send a check made payable to Treasury Obligations
Fund-- Institutional Service Shares to: Federated Services Company, Treasury
Obligations Fund, P.O. Box

8600, Boston, MA 02266-8600. Orders by mail are considered received when payment
by check is converted into federal funds. This is normally the next business day
after the check is received.

MINIMUM INVESTMENT REQUIRED

   
The minimum investment in the Fund is $1,000,000; ordinarily, this will be
achieved by the use of a master account established by the investor. Multiple
master accounts may be maintained by the same investor, but the minimum
investment for each master account will be $1,000,000. The management of the
Fund retains the right to waive the minimum investment requirement for master
accounts which the management reasonably believes will reach $1,000,000 at some
time within one year of the opening of the account.

    
   
 
    
       
CERTIFICATES AND CONFIRMATIONS

As transfer agent for the Fund, Federated Services Company maintains a share
account for each shareholder. Share certificates are not issued unless requested
by contacting the Fund or Federated Services Company in writing.

Monthly confirmations are sent to report transactions such as all purchases and
redemptions as well as dividends paid during the month.

DIVIDENDS

   
Dividends are declared daily and paid monthly. The amount of dividends declared
by the Fund is based on estimates of net interest income for the Fund. Actual
income may differ from estimates; these differences, if any, will be included in
the calculation of subsequent dividends. 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.

REDEEMING SHARES
- --------------------------------------------------------------------------------

Shares are redeemed at their net asset value next determined after Federated
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.

BY MAIL

Shares may be redeemed by sending a written request to: Treasury Obligations
Fund, Federated Services Company, P.O. Box 8600, Boston, MA 02266-8600. The
written request should state: Treasury Obligations Fund--Institutional Service
Shares; shareholder's name; the account number; and the share or dollar amount
requested. Sign the request exactly as the shares are registered. Shareholders
should call the Fund for assistance in redeeming by mail.

If share certificates have been issued, they must be properly endorsed and
should be sent by registered or overnight insured mail with the written request
to Federated Services Company, 500 Victory Road-2nd Floor, North Quincy, MA
02171.

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

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

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

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

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

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

Normally, a check for the proceeds is mailed within one business day, but in no
event more than seven days, after receipt of a proper written redemption
request. Dividends are paid up to and including the day that a redemption
request is processed.

TELEPHONE REDEMPTION

Shares may be redeemed by telephoning the Fund. 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. An
authorization form permitting the Fund to accept telephone requests must first
be completed. Authorization forms and information on this service are available
from Federated Securities Corp.

   
If the redemption request is received before 5:00 p.m. (Eastern time), the
proceeds 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, and those
shares redeemed will not be entitled to that day's dividend. A daily dividend
will be paid on shares redeemed if the redemption request is received after 5:00
p.m. (Eastern time). However, the proceeds are not wired until the following
business day. The Fund reserves the right to wire redemption proceeds within
seven days of a redemption request if, in the judgment of the adviser, an
earlier payment could adversely affect the Fund. . This procedure may be
modified or terminated by the transfer agent or the Fund.
    

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

Mail", should be considered. If at any time the Fund shall determine it
necessary to terminate or modify this method of redemption, shareholders would
be promptly notified.

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.

SHAREHOLDER INFORMATION
- --------------------------------------------------------------------------------

VOTING RIGHTS

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

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

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.

TAX INFORMATION
- --------------------------------------------------------------------------------

FEDERAL INCOME TAX

The Fund will pay no federal income tax because it expects to meet requirements
of the Internal Revenue Code, as amended, 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.

PENNSYLVANIA CORPORATE AND PERSONAL PROPERTY TAXES

In the opinion of Houston, Houston, & Donnelly, 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.

OTHER STATE AND LOCAL TAXES.  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 another class of shares called Institutional Shares.
Institutional Shares are sold at net asset value primarily to accounts for which
financial institutions act in an agency or fiduciary capacity, 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 Shares are distributed with no 12b-1 fees. Currently,
Institutional Shares are accruing no 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 1-800-235-4669.

PERFORMANCE INFORMATION
- --------------------------------------------------------------------------------

From time to time, the Fund advertises its yield and effective yield for shares.
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.

Advertisements and sales literature may also refer to total return. 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.

TREASURY OBLIGATIONS FUND
NOTES TO FINANCIAL STATEMENTS
JULY 31, 1995
- --------------------------------------------------------------------------------

(1) 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 diversified portfolios. The
financial statements included herein are only those of Treasury 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 Fund offers
two classes of shares: Institutional Shares and Institutional Service Shares.

(2) SIGNIFICANT ACCOUNTING POLICIES

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

     INVESTMENT VALUATIONS--The Fund's use of the amortized cost method to value
     its portfolio securities is 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 investment 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 paid under the repurchase
     agreement transaction.

     The Fund will only enter into repurchase agreements with banks and other
     recognized financial institutions, such as brokers/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.

TREASURY OBLIGATIONS FUND
- --------------------------------------------------------------------------------

     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 not to exceed a period of five
     years from the Fund's commencement date.

     OTHER--Investment transactions are accounted for on the trade date.

(3) 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, 1995, capital paid-in aggregated $3,984,922,273.
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, 1995, 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, 1995, 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, 1995, the results of its operations for the year then
ended, the changes in its net assets for each of the two years in the period
then ended, and the financial highlights for the periods presented, in
conformity with generally accepted accounting principles.
