The information set  forth in the  foregoing table and  example relates only  to

shares  called   Institutional   Shares.  Institutional   Service   Shares   and

Shares."


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 of beneficial interest 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 ("Shares") of the Fund, which are designed
primarily for financial institutions  as a convenient  means of accumulating  an
interest  in a professionally  managed, diversified portfolio  investing only in
short-term U.S. government securities. A  minimum initial investment of  $25,000
is required.

Eligibility   for  investment  in  the  Fund  is  contingent  upon  an  investor
accumulating and maintaining a minimum  aggregate investment of $200,000,000  in
Federated  funds within a twelve-month period.  For this purpose, 1) an investor
is defined as  a financial  institution or its  collective customers,  including
affiliate  financial  institutions  and  their  collective  customers,  or other
institutions that are determined to  qualify by Federated Securities Corp.,  and
2)  Federated funds  are those mutual  funds which are  distributed by Federated
Securities Corp., or are  advised by or administered  by investment advisers  or
administrators  affiliated with Federated  Securities Corp. ("Federated Funds").
An investor's minimum investment  will be calculated  by combining all  accounts
the investor maintains with the Federated Funds, which includes the Trust.

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

INVESTMENT INFORMATION
- --------------------------------------------------------------------------------

INVESTMENT OBJECTIVE

The investment objective of the Fund is current income consistent with stability
of principal. This  investment objective cannot  be changed without  shareholder
approval.  While there is no assurance that the Fund will achieve its investment
objective, it endeavors to do so by following the investment policies  described
in this prospectus.

INVESTMENT POLICIES

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


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

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

    - notes,  bonds,  and  discount  notes   of  U.S.  government  agencies   or
      instrumentalities,  such  as Central  Bank  for Cooperatives,  Farm Credit
      System, Farmers Home  Administration, Federal Farm  Credit Banks,  Federal
      Farm  Credit System, Federal  Home Loan Banks,  Federal Home Loan Mortgage
      Corporation,  Federal  Intermediate  Credit  Banks,  Federal  Land  Banks,
      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, brokers/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.

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, up to one-third of the value of its total assets 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.

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.


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.
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.  Total  assets  under  management   or
    administration  by these and  other subsidiaries of  Federated Investors are
    approximately $70 billion. Federated Investors, which was founded in 1956 as
    Federated Investors, Inc., develops and  manages mutual funds primarily  for
    the  financial industry.  Federated Investors'  track record  of competitive
    performance and  its disciplined,  risk averse  investment philosophy  serve
    approximately  3,500  client  institutions  nationwide.  Through  these same
    client institutions, individual shareholders also  have access to this  same
    level of investment expertise.

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.

DISTRIBUTION AND SHAREHOLDER SERVICES PLANS.  Under a distribution plan  adopted
in  accordance with Investment Company Act Rule 12b-1 (the "Distribution Plan"),
the Fund will pay to  the distributor an amount, computed  at an annual rate  of
.25  of 1%  of the average  daily net  asset value of  the Institutional Service
Shares to finance any  activity which is principally  intended to result in  the
sale  of shares  subject to  the Distribution  Plan. The  distributor may select
financial institutions such as banks, fiduciaries, custodians for public  funds,
investment  advisers, and  broker/dealers to  provide sales  support services as
agents for  their clients  or customers.  In addition,  the Fund  has adopted  a
Shareholder  Services  Plan  (the  "Services  Plan")  under  which  it  will pay
financial institutions an amount  not exceeding .25 of  1% of the average  daily
net  asset value of  the Institutional Service  Shares to provide administrative
support services to their  customers who own  shares of the  Fund. From time  to
time and for such periods as deemed appropriate, the amounts stated above may be
reduced  voluntarily.  Activities  and  services  under  these  arrangements may
include, but are not limited  to, providing advertising and marketing  materials
to  prospective shareholders,  providing personal services  to shareholders, and
maintaining shareholder accounts.

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 or  the
distributor, as appropriate.

The  Distribution Plan is a  compensation-type plan. As such,  the Fund makes no
payments to the distributor except as described above. Therefore, the Fund  does
not pay for unreimbursed expenses of the distributor, including amounts expended
by    the    distributor    in    excess    of    amounts    received    by   it


from the Fund, interest, carrying or other financing charges in connection  with
excess  amounts expended, or  the distributor's overhead  expenses. However, the
distributor may be able to recover such amounts or may earn a profit from future
payments made by the Fund under the Distribution Plan.

ADMINISTRATION OF THE FUND

ADMINISTRATIVE SERVICES.   Federated  Administrative Services,  a subsidiary  of
Federated  Investors,  provides  certain 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
which relates to the average aggregate  daily net assets of all Federated  Funds
as specified below:

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  at 12:00  noon, 3:00  p.m., and  4:00 p.m.
(Boston time) Monday through Friday except on:  (i) days on which there are  not
sufficient  changes in the value of the Fund's portfolio securities that its net
asset value might be materially affected;  (ii) days during which no shares  are
tendered  for redemption and no orders to purchase shares are received; or (iii)
the following holidays: New Year's  Day, 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.,
(Boston  time) to place an order.  The order is considered received immediately.
Payment by federal funds must be  received before 3:00 p.m., (Boston time)  that
day.  Federal funds  should be  wired as  follows: State  Street Bank  and Trust
Company, Boston, Massachusetts; 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:  Government  Obligations
Fund,  P.O.  Box  8602, Boston,  Massachusetts  02266-8602. 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 initial  investment is $25,000.  Eligibility for  investment in the
Fund is  contingent upon  an  investor accumulating  and maintaining  a  minimum
aggregate  investment of $200,000,000  in Federated Funds  within a twelve-month
period.

SUBACCOUNTING SERVICES

Financial institutions are encouraged to  open single master accounts.  However,
certain   financial  institutions   may  wish   to  use   the  transfer  agent's
subaccounting system to minimize their internal recordkeeping requirements.  The
transfer  agent  charges a  fee  based on  the  level of  subaccounting services
rendered. Financial institutions may charge  or pass through subaccounting  fees
as  part of or in addition to normal trust or agency account fees. They may also
charge fees for other services provided which may be related to the ownership of
Fund shares.  This  prospectus should,  therefore,  be read  together  with  any
agreement  between the customer and the financial institution with regard to the
services provided, the fees charged for those services and any restrictions  and
limitations imposed.

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. Shares purchased by wire before
3:00 p.m. (Boston time)  begin earning dividends that  day. Shares purchased  by
check  begin earning  dividends on  the day  after the  check is  converted into
federal funds.  Dividends  are  automatically reinvested  in  additional  Shares
unless cash payments are requested by contacting the Fund.

CAPITAL GAINS

Capital  gains, if any, could result in an increase in dividends. Capital losses
could result in a decrease in dividends. If, for some extraordinary reason,  the
Fund realizes net long-term capital gains, it will distribute them at least once
every 12 months.


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

Shares  are redeemed  at their  net asset value  next determined  after the Fund
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,  P.O.  Box 8602,  Boston,  Massachusetts 02266-8602.  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 certified mail with the written request.

Shareholders requesting a  redemption of $50,000  or more, 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 firm 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 its 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. If the  redemption request is
received before 12:00 noon  (Boston 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 (Boston  time). However,  the
proceeds  are  not  wired  until  the  following  business  day.  Under  limited
circumstances, arrangements may be


made with the distributor for same-day  payment of proceeds, without that  day's
dividend, for redemption requests received before 3:00 p.m., Boston time.

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. Telephone redemption instructions may
be recorded.

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

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 $25,000 or the aggregate
investment in Federated Funds falls  below the required minimum of  $200,000,000
to  be maintained  from and  after twelve  months from  account opening,  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 June 28, 1994, Var &
Co., St. Paul, Minnesota owned  28% of the voting  securities of the Fund,  and,
therefore,  may, for certain purposes, be deemed to control the Fund and be able
to affect the outcome of certain matters presented for a vote of shareholders.
    

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.

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.

PENNSYLVANIA CORPORATE AND PERSONAL PROPERTY TAXES

In the opinion of Houston, Houston & Donnelly, counsel to the Fund:

    - the Fund is  not subject  to Pennsylvania corporate  or personal  property
      taxes; and

    - 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.

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

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

Performance figures  will be  calculated separately  for each  class of  shares.
Because  each class of shares is  subject to different expenses, the performance
of  Institutional  Shares  will  exceed   the  yield  and  effective  yield   of
Institutional Service Shares for the same period.

From time to time the Fund may advertise its performance using certain financial
publications and/or compare its performance to certain indices.

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

Institutional Shares are sold at net asset value to accounts for which financial
institutions   act  in   an  agency   or  fiduciary   capacity.  Investments  in
Institutional Shares are  subject to  a minimum initial  investment of  $25,000.
Institutional Shares are not sold pursuant to a 12b-1 Plan.

Financial  institutions  providing distribution  or administrative  services may
receive different compensation depending upon which class of shares of the  Fund
is sold. The amount of dividends payable to shareholders of Institutional Shares
will  exceed that payable to the shareholders of Institutional Service Shares by
the difference  between class  expenses and  any 12b-1  Plan expenses  borne  by
Institutional  Service  Shares. The  stated advisory  fee is  the same  for both
classes of shares.

INVESTMENT POLICIES
- --------------------------------------------------------------------------------

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

VARIABLE RATE U.S. GOVERNMENT SECURITIES

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

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

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

REPURCHASE AGREEMENTS

The Fund or its custodian will take possession of the securities subject to
repurchase agreements, and these securities will be marked to market daily. In
the event that a defaulting seller filed for bankruptcy or became insolvent,
disposition of such securities by the Fund might be delayed pending court
action. The Fund believes that under the regular procedures normally in effect
for custody of the Fund's portfolio securities subject to repurchase agreements,
a court of competent jurisdiction would rule in favor of the Fund and allow
retention or disposition of such securities. The Fund will only enter into
repurchase agreements with banks and other recognized financial institutions,
such as broker/dealers, which are deemed by the Fund's adviser to be
creditworthy pursuant to guidelines established by the Trustees.

REVERSE REPURCHASE AGREEMENTS

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

LENDING OF PORTFOLIO SECURITIES

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

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

INVESTMENT LIMITATIONS
- --------------------------------------------------------------------------------

SELLING SHORT AND BUYING ON MARGIN

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

ISSUING SENIOR SECURITIES AND BORROWING MONEY

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

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

PLEDGING ASSETS

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

LENDING CASH OR SECURITIES

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

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

INVESTING IN COMMODITIES

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

INVESTING IN REAL ESTATE

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

UNDERWRITING

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

CONCENTRATION OF INVESTMENTS

The Fund will not invest 25% or more of the value of its total assets in any one
industry, except that the Fund may invest 25% or more of the value of its total
assets in cash, cash items, or securities issued or guaranteed by the government
of the United States or its agencies, or instrumentalities and repurchase
agreement collateralized by such U.S. government securities.

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

DIVERSIFICATION OF INVESTMENTS

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

INVESTING IN RESTRICTED SECURITIES

The Fund will not invest in securities subject to restrictions on resale under
federal securities law.

INVESTING IN ILLIQUID SECURITIES

The Fund will not invest more than 10% of the value of its net assets in
illiquid securities.

INVESTING IN SECURITIES OF OTHER INVESTMENT COMPANIES

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

INVESTING IN NEW ISSUERS

The Fund will not invest more than 5% of the value of its total assets in
securities of issuers which have records of less than three years of continuous
operations, including the operation of any predecessor.

INVESTING FOR CONTROL

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

INVESTING IN ISSUERS WHOSE SECURITIES ARE OWNED BY OFFICERS OF THE TRUST

The Fund will not purchase or retain the securities of any issuer if the
Officers and Trustees of the Trust or its investment adviser owning individually
more than .50 of 1% of the issuer's securities together own more than 5% of the
issuer's securities.

INVESTING IN OPTIONS

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

INVESTING IN MINERALS

The Fund will not purchase or sell interests in oil, gas, or other mineral
exploration or development programs or leases, although it may purchase the
securities of issuers which invest in or sponsor such programs.

For purposes of the above limitations, the Fund considers certificates of
deposit and demand and time deposits issued by a U.S. branch of a domestic bank
or savings and loan having capital, surplus, and undivided profits in excess of
$100,000,000 at the time of investment to be "cash items". Except with respect
to borrowing money, if a percentage limitation is adhered to at the time of
investment, a later increase or decrease in percentage resulting from any change
in value or net assets will not result in a violation of such limitation.

The Fund did not borrow money, issue senior securities, pledge securities,
invest in illiquid securities, or engage in when-issued and delayed delivery
transactions or reverse repurchase agreements in excess of 5% of the value of
its net assets during the last fiscal period and has no present intent to do so
during the coming fiscal year.

BROKERAGE TRANSACTIONS
- --------------------------------------------------------------------------------

When selecting brokers and dealers to handle the purchase and sale of portfolio
instruments, the adviser looks for prompt execution of the order at a favorable
price. In working with dealers, the adviser will generally use those who are
recognized dealers in specific portfolio instruments, except when a better price
and execution of the order can be obtained elsewhere. The adviser makes
decisions on portfolio transactions and selects brokers and dealers subject to
guidelines established by the Board of Trustees. The adviser may select brokers
and dealers who offer brokerage and research services. These services may be
furnished directly to the Fund or to the adviser and may include: advice as to
the advisability of investing in securities; security analysis and reports;
economic studies; industry studies; receipt of quotations for portfolio
evaluations; and similar services. Research services

- --------------------------------------------------------------------------------
provided by brokers and dealers may be used by the adviser or its affiliates in
advising the Trust and other accounts. To the extent that receipt of these
services may supplant services for which the adviser or its affiliates might
otherwise have paid, it would tend to reduce their expenses. The adviser and its
affiliates exercise reasonable business judgment in selecting brokers who offer
brokerage and research services to execute securities transactions. They
determine in good faith that commissions charged by such persons are reasonable
in relationship to the value of the brokerage and research services provided.
During the fiscal year(s) ended July 31, 1993, 1992 and 1991, the Trust paid no
brokerage commissions.

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

TRUSTEE LIABILITY

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

INVESTMENT ADVISORY SERVICES
- --------------------------------------------------------------------------------

INVESTMENT ADVISER(S)

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

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

ADVISORY FEES

For its advisory services, Federated Management receives an annual investment
advisory fee as described in the prospectus. For the fiscal years ended July 31,
1993, 1992 and 1991, the Fund's adviser earned $1,343,686, $910,523, and
$434,684, respectively for services provided on behalf of Institutional Shares,
of which $768,184, $552,320, and $434,684, respectively, were voluntarily waived
because of undertakings to limit the Fund's expenses.

    STATE EXPENSE LIMITATIONS

      The adviser has undertaken to comply with the expense limitations
      established by certain states for investment companies whose shares are
      registered for sale in those states. If the Fund's normal operating
      expenses (including the investment advisory fee, but not including
      brokerage commissions, interest, taxes, and extraordinary expenses) exceed
      2 1/2% per year of the first $30 million of average net assets, 2% per
      year of the next $70 million of average net assets, and 1 1/2% per year of
      the remaining average net assets, the adviser will reimburse the Fund for
      its expenses over the limitation.

      If the Fund's monthly projected operating expenses exceed this limitation,
      the investment advisory fee paid will be reduced by the amount of the
      excess, subject to an annual adjustment. If the expense limitation is
      exceeded, the amount to be reimbursed by the adviser will be limited, in
      any single fiscal year, by the amount of the investment advisory fees.

      This arrangement is not part of the advisory contract and may be amended
      or rescinded in the future.

FUND ADMINISTRATION
- --------------------------------------------------------------------------------

Federated Administrative Services, a subsidiary of Federated Investors, provides
administrative personnel and services to the Trust for a fee as described in the
prospectus for each class of shares of the Fund. For the fiscal years ended July
31, 1993, 1992, and 1991, Federated Administrative Services, Inc., the Trust's
former administrator, earned $377,706, $274,492, and $253,110, respectively.
John A. Staley, IV, an officer of the Trust and Dr. Henry J. Gailliot, an
officer of Federated Management, the adviser to the Fund, each hold
approximately 15% and 20%, respectively, of the outstanding common stock of
Commercial Data Services, Inc., a company which provides computer processing
services to Federated Administrative Services, Inc., and Federated
Administrative Services. For the fiscal years ended December 31, 1993, 1992, and
1991, Federated Administrative Services, Inc. paid approximately $161,547,
$201,799, and $170,529, respectively for services provided by Commercial Data
Services, Inc., to the Funds.

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

SHAREHOLDER SERVICES PLAN
- --------------------------------------------------------------------------------

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

DISTRIBUTION PLAN
- --------------------------------------------------------------------------------

With respect to Institutional Service Shares the Fund has adopted a Plan
pursuant to Rule 12b-1 which was promulgated by the Securities and Exchange
Commission pursuant to the Investment Company Act of 1940. The Plan permits the
payment of fees to brokers for distribution and administrative services and to
administrators for administrative services. The Plan is designed to (i)
stimulate brokers to provide distribution and administrative support services to
shareholders and (ii) stimulate administrators to render administrative support
services to shareholders. The administrative services are provided by a
representative who has knowledge of the shareholder's particular circumstances
and goals. By adopting the Plan, the Board of Trustees expects that the Fund
will be able to achieve a more predictable flow of cash for investment purposes
and to meet redemptions. This will facilitate more efficient portfolio
management and assist the Fund in seeking to achieve its investment objectives.
By identifying potential investors whose needs are served by the Fund's
objectives, and properly servicing these accounts, it may be possible to curb
sharp fluctuations in rates of redemptions and sales. Other benefits may
include: (1) an efficient and effective administrative system; (2) a more
efficient use of shareholder assets by having them rapidly invested with a
minimum of delay and administrative detail; and (3) an efficient and reliable
shareholder records system and prompt responses to shareholder requests and
inquiries concerning their accounts.

CUSTODIAN AND PORTFOLIO RECORDKEEPER.  State Street Bank and Trust Company,
Boston, Massachusetts is custodian for the securities and cash of the Fund.
Federated Services Company, Pittsburgh, Pennsylvania provides certain accounting
and recordkeeping services with respect to the Fund's portfolio investments.

DETERMINING NET ASSET VALUE
- --------------------------------------------------------------------------------

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

The Fund's use of the amortized cost method of valuing portfolio instruments
depends on its compliance with certain conditions in Rule 2a-7 (the "Rule")
promulgated by the Securities and Exchange Commission under the Investment
Company Act of 1940. Under the Rule, the Trustees must establish procedures
reasonably designed to stabilize the net asset value per share, as computed for
purposes of distribution and redemption, at $1.00 per share, taking into account
current market conditions and the Fund's investment objective. The procedures
include monitoring the relationship between the amortized cost value per share
and the net asset value per share based upon available indications of market
value. The Trustees will decide what, if any, steps should be taken if there is
a difference of more than 0.5 of 1% between the two values. The Trustees will
take any steps they consider appropriate (such as redemption in kind or
shortening the average portfolio maturity) to minimize any material dilution or
other unfair results arising from differences between the two methods of
determining net asset value.

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

REDEMPTION IN KIND
- --------------------------------------------------------------------------------

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

THE FUND'S TAX STATUS
- --------------------------------------------------------------------------------

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

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

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

YIELD

The Fund calculates its yield based upon the seven days ending on the day of the
calculation, called the "base period." This yield is computed by: determining
the net change in the value of a hypothetical account with a balance of one
share at the beginning of the base period, with the net change excluding capital
changes but including the value of any additional shares purchased with
dividends earned from the original one share and all dividends declared on the
original and any purchased shares; dividing the net change in the account's
value by the value of the account at the beginning of the base period to
determine the base period return; and multiplying the base period return by
365/7.

EFFECTIVE YIELD

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

TOTAL RETURN

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

PERFORMANCE COMPARISONS

Investors may use financial publications and/or indices to obtain a more
complete view of the Fund's performance. When comparing performance, investors
should consider all relevant factors such as the composition of any index used,
prevailing market conditions, portfolio compositions of other funds, and methods
used to

GOVERNMENT OBLIGATIONS FUND
NOTES TO FINANCIAL STATEMENTS
JULY 31, 1993
- --------------------------------------------------------------------------------

(1) ORGANIZATION

Government Obligations Fund (the "Fund") is a diversified portfolio and one of
the portfolios of Money Market Obligations Trust (the "Trust"), a no-load,
open-end, management investment company, which is registered under the
Investment Company Act of 1940, as amended. 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.

(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.

A.  INVESTMENT VALUATIONS--The Board of Trustees ("Trustees") has determined
    that the best method currently available for valuing portfolio securities is
    amortized cost. The Fund's use of the amortized cost method to value its
    portfolio securities is conditioned on its compliance with Rule 2a-7 under
    the Investment Company Act of 1940, as amended.

B.  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 in support of repurchase agreement
    investments. Additionally, procedures have been established by the Fund to
    monitor on a daily basis, the market value of each repurchase agreement's
    underlying securities to ensure the existence of a proper level of
    collateral.

    The Fund will only enter into repurchase agreements with banks and other
    recognized financial institutions such as broker/dealers which are deemed by
    the Fund's adviser to be creditworthy pursuant to guidelines established by
    the Trustees. 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.

C.  INCOME--Interest income is recorded on the accrual basis. Interest income
    includes interest and discount earned (net of premium), including original
    issue discount as required by the Internal Revenue Code, plus realized net
    gains, if any, on portfolio securities.

D.  FEDERAL TAXES--It is the Fund's policy to comply with the provisions of the
    Internal Revenue Code applicable to investment companies and to distribute
    to shareholders each year all of its taxable income. Accordingly, no
    provision for federal tax is necessary.

E.  WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS--The Fund may engage in
    when-issued or delayed delivery transactions. To the extent the Fund engages
    in such transactions, it will do so for the purpose of acquiring portfolio
    securities consistent with its investment objective and policies and not for
    the purpose of investment leverage. The Fund will record a when-issued
    security and the related liability on the trade date. Until the securities
    are received and paid for, the Fund will maintain 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.

F.  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 the shares, have been deferred and are being
    amortized using the straight-line method through December, 1994.

G.  OTHER--Investment transactions are accounted for on the date of the
    transaction.

(3) DIVIDENDS

The Fund computes its net income daily and, immediately prior to the calculation
of its net asset value at the close of business, declares and records dividends
to shareholders of record at the time of the previous computation of the Fund's
net asset value. Payment of dividends is made monthly in cash, or in additional
shares at the net asset value on the payable date.

(5) INVESTMENT ADVISORY FEE AND OTHER TRANSACTIONS WITH AFFILIATES

Federated Management, the Fund's investment adviser ("Adviser"), receives for
its services an annual investment advisory fee equal to 0.20 of 1% of the Fund's
average daily net assets. For the year ended July 31, 1993, the Adviser
voluntarily agreed to waive the amount, limited to the amount of the advisory
fee, by which the Fund's aggregate annual operating expenses (including its
investment advisory fee but excluding interest, taxes, brokerage commissions,
insurance premiums, and extraordinary expenses) exceed 0.20 of 1% of its average
daily net assets. This does not include reimbursement to the Fund of any
expenses incurred by shareholders who use the transfer agent's subaccounting
facilities. The Adviser can terminate this voluntary agreement at any time at
its sole discretion. For the year ended July 31, 1993, the Adviser earned an
investment advisory fee of $1,343,686 of which $768,184 was voluntarily waived
in accordance with such agreement.

Federated Services Company, the Fund's recordkeeper, received for its services a
fee of $93,995 for the year ended July 31, 1993.

Administrative personnel and services were provided at approximate cost by
Federated Administrative Services, Inc. Certain Officers and Trustees of the
Trust are Officers and Directors of the above corporation.

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, 1993, and 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 (see page 2 of the
prospectus) for each of the three years in the period then ended and for the
period from March 31, 1990 (date of initial public investment) to July 31, 1990.
These financial statements and financial highlights are the responsibility of
the Trusts 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 the securities owned as of
July 31, 1993, 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
Government Obligations Fund (an investment portfolio of Money Market Obligations
Trust) as of July 31, 1993, 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 each of the three years in the
period then ended and for the period from March 31, 1990 (date of initial public
investment) to July 31, 1990, in conformity with generally accepted accounting
principles.

Shares."

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 of beneficial interest 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 ("Shares") of the Fund, which are designed
primarily for financial institutions  as a convenient  means of accumulating  an
interest  in  a  professionally  managed,  diversified  portfolio  investing  in
short-term money market securities. A  minimum initial investment of $25,000  is
required.

Eligibility   for  investment  in  the  Fund  is  contingent  upon  an  investor
accumulating and maintaining a minimum  aggregate investment of $200,000,000  in
Federated  funds within a twelve-month period.  For this purpose, 1) an investor
is defined as  a financial  institution or its  collective customers,  including
affiliate  financial  institutions  and  their  collective  customers,  or other
institutions that are determined to  qualify by Federated Securities Corp.,  and
2)  Federated funds  are those mutual  funds which are  distributed by Federated
Securities Corp., or are  advised by or administered  by investment advisers  or
administrators  affiliated with Federated  Securities Corp. ("Federated Funds").
An investor's minimum investment  will be calculated  by combining all  accounts
the investor maintains with the Federated Funds, which includes the Trust.

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

INVESTMENT INFORMATION
- --------------------------------------------------------------------------------

INVESTMENT OBJECTIVE

The investment objective of the Fund is current income consistent with stability
of principal. This  investment objective cannot  be changed without  shareholder
approval.  While there is no assurance that the Fund will achieve its investment
objective, it endeavors to do so by following the investment policies  described
in this prospectus.

INVESTMENT POLICIES

The  Fund pursues its investment objective by  investing in a portfolio of money
market securities maturing  in 13 months  or less. The  average maturity of  the
securities in the Fund's portfolio, computed on a dollar-weighted basis, will be
90  days or less. Unless indicated otherwise, 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
      ("Government Securities"); 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 an interest index or a stated percentage of a prime rate or
another published rate. 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.

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.

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.

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  Corporation ("S&P"),  Prime-1 by  Moody's Investors  Service,
Inc. ("Moody's"), or F-1 (+ or -) by Fitch Investors Service, Inc. ("Fitch") are
all  considered rated in  the highest short-term rating  category. The Fund will
follow applicable regulations in  determining whether a  security rated by  more
than  one  NRSRO  can be  treated  as  being in  the  highest  short-term rating
category; currently,  such securities  must  be rated  by  two NRSROs  in  their
highest rating category. See "Regulatory Compliance."

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  not treat credit enhanced  securities as having been  issued by the credit
enhancer for  diversification  purposes. However,  under  certain  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.

REPURCHASE AGREEMENTS.   Certain securities  in which  the Fund  invests may  be
purchased   pursuant  to   repurchase  agreements.   Repurchase  agreements  are
arrangements in  which banks,  brokers/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.

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.

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, up to one-third of the value of its total assets 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.

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.

CONCENTRATION  OF INVESTMENTS.  Generally, in excess of 50% of the assets of the
Fund will be invested  in commercial paper and  variable rate demand notes.  The
Fund  will 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
certificates  of deposit and demand and time deposits issued by a U.S. branch of
a domestic  bank or  savings and  loan having  capital, surplus,  and  undivided
profits in excess of $100,000,000 at the time of investment.

INVESTMENT RISKS

ECDs,  ETDs, Yankee CDs, CCPs 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.

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.  Total  assets  under  management  or
    administration by these  and other subsidiaries  of Federated Investors  are
    approximately $70 billion. Federated Investors, which was founded in 1956 as
    Federated  Investors, Inc., develops and  manages mutual funds primarily for
    the financial  industry. Federated  Investors' track  record of  competitive
    performance  and its  disciplined, risk  averse investment  philosophy serve
    approximately 3,500  client  institutions  nationwide.  Through  these  same
    client  institutions, individual shareholders also  have access to this same
    level of investment expertise.

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.

DISTRIBUTION  AND SHAREHOLDER SERVICES PLANS.  Under a distribution plan adopted
in accordance with Investment Company Act Rule 12b-1 (the "Distribution  Plan"),
the  Fund will pay to  the distributor an amount, computed  at an annual rate of
.25 of 1%  of the average  daily net  asset value of  the Institutional  Service
Shares  to finance any activity  which is principally intended  to result in the
sale of shares  subject to  the Distribution  Plan. The  distributor may  select
financial  institutions such as banks, fiduciaries, custodians for public funds,
investment advisers, and  broker/dealers to  provide sales  support services  as
agents  for their  clients or  customers. In  addition, the  Fund has  adopted a
Shareholder Services  Plan  (the  "Services  Plan")  under  which  it  will  pay
financial  institutions an amount not  exceeding .25 of 1%  of the average daily
net asset value of  the Institutional Service  Shares to provide  administrative
support  services  to their  customers who  own  shares of  the Fund.  From time

to time and for such periods as deemed appropriate, the amounts stated above may
be reduced voluntarily.  Activities and  services under  these arrangements  may
include,  but are not limited to,  providing advertising and marketing materials
to prospective shareholders,  providing personal services  to shareholders,  and
maintaining shareholder accounts.

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 or the
distributor, as appropriate.

The Distribution Plan is  a compensation-type plan. As  such, the Fund makes  no
payments  to the distributor except as described above. Therefore, the Fund does
not pay for unreimbursed expenses of the distributor, including amounts expended
by the distributor in excess of amounts received by it from the Fund,  interest,
carrying  or other financing charges in connection with excess amounts expended,
or the distributor's overhead expenses. However, the distributor may be able  to
recover  such amounts or may earn a profit from future payments made by the Fund
under the Distribution Plan.

ADMINISTRATION OF THE FUND

ADMINISTRATIVE SERVICES.   Federated  Administrative Services,  a subsidiary  of
Federated  Investors,  provides  certain 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
which relates to the average aggregate  daily net assets of all Federated  Funds
as specified below:

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  allocated to the Shares  as a class are  expenses
under  the Fund's Rule 12b-1 Plan and  Shareholder Services Plan which relate to
the Shares.  However, the  Board  of Trustees  reserves  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  at 12:00  noon, 3:00  p.m., and  4:00 p.m.
(Boston time) Monday through Friday except on:  (i) days on which there are  not
sufficient  changes in the value of the Fund's portfolio securities that its net
asset value might be materially affected;  (ii) days during which no shares  are
tendered  for redemption and no orders to purchase shares are received; or (iii)
the following holidays: New Year's  Day, 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.,
(Boston time) to place an order.  The order is considered received  immediately.
Payment  by federal funds must be received  before 3:00 p.m., (Boston time) that
day. Federal  funds should  be wired  as follows:  State Street  Bank and  Trust
Company,  Boston,  Massachusetts;  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.

BY MAIL.  To purchase  by mail, send a check  made payable to Prime  Obligations
Fund  -- Institutional Service Shares to: Prime Obligations Fund, P.O. Box 8602,
Boston, Massachusetts 02266-8602.  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 initial  investment is  $25,000. Eligibility for  investment in  the
Fund  is  contingent upon  an investor  accumulating  and maintaining  a minimum
aggregate investment of  $200,000,000 in Federated  Funds within a  twelve-month
period.

SUBACCOUNTING SERVICES

Financial  institutions are encouraged to  open single master accounts. However,
certain  financial  institutions   may  wish   to  use   the  transfer   agent's
subaccounting  system to minimize their internal recordkeeping requirements. The
transfer agent  charges a  fee  based on  the  level of  subaccounting  services
rendered.  Financial institutions may charge  or pass through subaccounting fees
as part of or in addition to normal trust or agency account fees. They may  also
charge fees for other services provided which may be related to the ownership of
Fund  shares.  This  prospectus should,  therefore,  be read  together  with any
agreement between the customer and the financial institution with regard to  the
services  provided, the fees charged for those services and any restrictions and
limitations imposed.

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. Shares purchased by wire  before
3:00  p.m. (Boston time)  begin earning dividends that  day. Shares purchased by
check begin  earning dividends  on the  day after  the check  is converted  into
federal  funds.  Dividends  are automatically  reinvested  in  additional Shares
unless cash payments are requested by contacting the Fund.

CAPITAL GAINS

Capital gains, if any, could result in an increase in dividends. Capital  losses
could  result in a decrease in dividends. If, for some extraordinary reason, the
Fund realizes net long-term capital gains, it will distribute them at least once
every 12 months.

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

Shares are redeemed  at their  net asset value  next determined  after the  Fund
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,
P.O. Box  8602, Boston,  Massachusetts 02266-8602.  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 certified mail with the written request.

Shareholders  requesting a  redemption of $50,000  or more, 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 firm 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 its 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. If  the redemption request  is
received  before 12:00 noon (Boston  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  (Boston time).  However, the
proceeds  are  not  wired  until  the  following  business  day.  Under  limited
circumstances,  arrangements  may  be  made with  the  distributor  for same-day
payment of  proceeds,  without  that day's  dividend,  for  redemption  requests
received before 3:00 p.m., Boston time.

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. Telephone redemption instructions may
be recorded.

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.

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

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 $25,000 or the aggregate
investment in Federated Funds falls  below the required minimum of  $200,000,000
to  be maintained  from and  after twelve  months from  account opening,  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 April 28,
1994, Var & Co., St.  Paul, Minnesota, owned 32.3%  of the voting securities  of
the Fund, and, therefore, may for certain purposes be deemed to control the Fund
and  be able to  affect the outcome of  certain matters presented  for a vote of
shareholders.

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.

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.

PENNSYLVANIA CORPORATE AND PERSONAL PROPERTY TAXES

In the opinion of Houston, Houston & Donnelly, counsel to the Fund:

    - the  Fund is  not subject to  Pennsylvania corporate  or personal property
      taxes; and

    - 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.

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

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

Performance  figures will  be calculated  separately for  each class  of shares.
Because each class of shares is  subject to different expenses, the  performance
of   Institutional  Shares  will  exceed  the   yield  and  effective  yield  of
Institutional Service Shares for the same period.

From time  to  time,  the  Fund may  advertise  its  performance  using  certain
financial publications and/or compare its performance with certain indices.

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

Institutional Shares are sold at net asset value to accounts for which financial
institutions   act  in   an  agency   or  fiduciary   capacity.  Investments  in
Institutional Shares are  subject to  a minimum initial  investment of  $25,000.
Institutional Shares are not sold pursuant to a 12b-1 Plan.

Financial  institutions  providing distribution  or administrative  services may
receive different compensation depending upon which class of shares of the  Fund
is sold. The amount of dividends payable to shareholders of Institutional Shares
will  exceed that payable to the shareholders of Institutional Service Shares by
the difference  between class  expenses and  any 12b-1  Plan expenses  borne  by
Institutional  Service  Shares. The  stated advisory  fee is  the same  for both
classes of shares.

INVESTMENT POLICIES
- --------------------------------------------------------------------------------

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

BANK INSTRUMENTS

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

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

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

REPURCHASE AGREEMENTS

The Fund or its custodian will take possession of the securities subject to
repurchase agreements, and these securities will be marked to market daily. In
the event that a defaulting seller filed for bankruptcy or became insolvent,
disposition of such securities by the Fund might be delayed pending court
action. The Fund believes that under the regular procedures normally in effect
for custody of the Fund's portfolio securities subject to repurchase agreements,
a court of competent jurisdiction would rule in favor of the Fund and allow
retention or disposition of such securities. The Fund will only enter into
repurchase agreements with banks and other recognized financial institutions,
such as broker/dealers, which are deemed by the Fund's adviser to be
creditworthy pursuant to guidelines established by the Trustees.

REVERSE REPURCHASE AGREEMENTS

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

U.S. GOVERNMENT OBLIGATIONS

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

    - the full faith and credit of the U.S. Treasury;

    - the issuer's right to borrow from the U.S. Treasury;

    - the discretionary authority of the U.S. government to purchase certain
      obligations of agencies or instrumentalities; or

    - the credit of the agency or instrumentality issuing the obligations.

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

LENDING OF PORTFOLIO SECURITIES

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

INVESTMENT LIMITATIONS
- --------------------------------------------------------------------------------

SELLING SHORT AND BUYING ON MARGIN

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

ISSUING SENIOR SECURITIES AND BORROWING MONEY

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

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

PLEDGING ASSETS

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

LENDING CASH OR SECURITIES

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

INVESTING IN COMMODITIES AND REAL ESTATE

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

UNDERWRITING

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

CONCENTRATION OF INVESTMENTS

The Fund will not invest 25% or more of the value of its total assets in any one
industry except that the Fund will generally invest 25% or more of the value of
its total assets in commercial paper issued by finance companies. The Fund may
invest 25% or more of the value of its total assets in cash, cash items, or
securities

- --------------------------------------------------------------------------------
issued or guaranteed by the government of the United States or its agencies or
instrumentalities and repurchase agreements collateralized by such U.S.
government securities.

DIVERSIFICATION OF INVESTMENTS

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

INVESTING IN RESTRICTED SECURITIES

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

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

INVESTING IN ILLIQUID SECURITIES

The Fund will not invest more than 10% of the value of its net assets in
illiquid securities.

INVESTING IN SECURITIES OF OTHER INVESTMENT COMPANIES

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

INVESTING IN NEW ISSUERS

The Fund will not invest more than 5% of the value of its total assets in
securities of issuers which have records of less than three years of continuous
operations, including the operation of any predecessor.

INVESTING FOR CONTROL

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

INVESTING IN ISSUERS WHOSE SECURITIES ARE OWNED BY OFFICERS OF THE TRUST

The Fund will not purchase or retain the securities of any issuer if the
Officers and Trustees of the Trust or its investment adviser owning individually
more than .50 of 1% of the issuer's securities together own more than 5% of the
issuer's securities.

INVESTING IN OPTIONS

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

INVESTING IN MINERALS

The Fund will not purchase or sell interests in oil, gas, or other mineral
exploration or development programs or leases, although it may purchase the
securities of issuers which invest in or sponsor such programs.

For purposes of the above limitations, the Fund considers certificates of
deposit and demand and time deposits issued by a U.S. branch of a domestic bank
or savings and loan having capital, surplus, and undivided profits in excess of
$100,000,000 at the time of investment to be "cash items." Except with respect
to borrowing money, if a percentage limitation is adhered to at the time of
investment, a later increase or decrease in percentage resulting from any change
in value or net assets will not result in a violation of such limitation.

The Fund did not issue senior securities, pledge securities, invest in illiquid
securities, or engage in when-issued and delayed delivery transactions or
reverse repurchase agreements in excess of 5% of the value of its net assets
during the last fiscal period and has no present intent to do so during the
coming fiscal year.

BROKERAGE TRANSACTIONS
- --------------------------------------------------------------------------------

When selecting brokers and dealers to handle the purchase and sale of portfolio
instruments, the adviser looks for prompt execution of the order at a favorable
price. In working with dealers, the adviser will generally use those

- --------------------------------------------------------------------------------
who are recognized dealers in specific portfolio instruments, except when a
better price and execution of the order can be obtained elsewhere. The adviser
makes decisions on portfolio transactions and selects brokers and dealers
subject to guidelines established by the Board of Trustees. The adviser may
select brokers and dealers who offer brokerage and research services. These
services may be furnished directly to the Fund or to the adviser and may
include: advice as to the advisability of investing in securities; security
analysis and reports; economic studies; industry studies; receipt of quotations
for portfolio evaluations; and similar services. Research services provided by
brokers and dealers may be used by the adviser or its affiliates in advising the
Trust and other accounts. To the extent that receipt of these services may
supplant services for which the adviser or its affiliates might otherwise have
paid, it would tend to reduce their expenses. The adviser and its affiliates
exercise reasonable business judgment in selecting brokers who offer brokerage
and research services to execute securities transactions. They determine in good
faith that commissions charged by such persons are reasonable in relationship to
the value of the brokerage and research services provided. During the fiscal
year(s) ended July 31, 1993, 1992 and 1991, the Trust paid no brokerage
commissions.

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

INVESTMENT ADVISORY SERVICES
- --------------------------------------------------------------------------------

INVESTMENT ADVISER(S)

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

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

ADVISORY FEES

For its advisory services, Federated Management receives an annual investment
advisory fee as described in the prospectus. For the fiscal years ended July 31,
1993, 1992 and 1991, the Fund's adviser earned $2,033,502, $1,227,947, and
$453,389, respectively, for services provided on behalf of Institutional Shares,
of which $955,268, $633,165, and $453,389, respectively, were voluntarily waived
because of undertakings to limit the Fund's expenses.

    STATE EXPENSE LIMITATIONS

      The adviser has undertaken to comply with the expense limitations
      established by certain states for investment companies whose shares are
      registered for sale in those states. If the Fund's normal operating
      expenses (including the investment advisory fee, but not including
      brokerage commissions, interest, taxes, and extraordinary expenses) exceed
      2 1/2% per year of the first $30 million of average net assets, 2% per
      year of the next $70 million of average net assets, and 1 1/2% per year of
      the remaining average net assets, the adviser will reimburse the Fund for
      its expenses over the limitation.

      If the Fund's monthly projected operating expenses exceed this limitation,
      the investment advisory fee paid will be reduced by the amount of the
      excess, subject to an annual adjustment. If the expense limitation is
      exceeded, the amount to be reimbursed by the adviser will be limited, in
      any single fiscal year, by the amount of the investment advisory fees.

      This arrangement is not part of the advisory contract and may be amended
      or rescinded in the future.

FUND ADMINISTRATION
- --------------------------------------------------------------------------------

Federated Administrative Services, a subsidiary of Federated Investors, provides
administrative personnel and services to the Trust for a fee as described in the
prospectus for each class of shares of the Fund. For the fiscal years ended July
31, 1993, 1992, and 1991, Federated Administrative Services, Inc., the Trust's
former administrator, earned $455,288, $283,251, and $248,329, respectively.
John A. Staley, IV, an officer of the Trust and Dr. Henry J. Gailliot, an
officer of Federated Management, the adviser to the Fund, each hold
approximately 15% and 20%,

- --------------------------------------------------------------------------------
respectively, of the outstanding common stock of Commercial Data Services, Inc.,
a company which provides computer processing services to Federated
Administrative Services, Inc., and Federated Administrative Services. For the
fiscal years ended December 31, 1993, 1992, and 1991, Federated Administrative
Services, Inc. paid approximately $161,547, $201,799, and $170,529, respectively
for services provided by Commercial Data Services, Inc., to the Funds.

SHAREHOLDER SERVICES PLAN
- --------------------------------------------------------------------------------

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

DISTRIBUTION PLAN
- --------------------------------------------------------------------------------

With respect to Institutional Service Shares the Fund has adopted a Plan
pursuant to Rule 12b-1 which was promulgated by the Securities and Exchange
Commission pursuant to the Investment Company Act of 1940. The Plan permits the
payment of fees to brokers for distribution and administrative services and to
administrators for administrative services. The Plan is designed to (i)
stimulate brokers to provide distribution and administrative support services to
shareholders and (ii) stimulate administrators to render administrative support
services to shareholders. The administrative services are provided by a
representative who has knowledge of the shareholder's particular circumstances
and goals. By adopting the Plan, the Board of Trustees expects that the Fund
will be able to achieve a more predictable flow of cash for investment purposes
and to meet redemptions. This will facilitate more efficient portfolio
management and assist the Fund in seeking to achieve its investment objectives.
By identifying potential investors whose needs are served by the Fund's
objectives, and properly servicing these accounts, it may be possible to curb
sharp fluctuations in rates of redemptions and sales. Other benefits may
include: (1) an efficient and effective administrative system; (2) a more
efficient use of shareholder assets by having them rapidly invested with a
minimum of delay and administrative detail; and (3) an efficient and reliable
shareholder records system and prompt responses to shareholder requests and
inquiries concerning their accounts.

CUSTODIAN AND PORTFOLIO RECORDKEEPER. State Street Bank and Trust Company,
Boston, Massachusetts is custodian for the securities and cash of the Fund.
Federated Services Company, Pittsburgh, Pennsylvania provides certain accounting
and recordkeeping services with respect to the Fund's portfolio investments.

DETERMINING NET ASSET VALUE
- --------------------------------------------------------------------------------

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

The Fund's use of the amortized cost method of valuing portfolio instruments
depends on its compliance with certain conditions in Rule 2a-7 (the "Rule")
promulgated by the Securities and Exchange Commission under the Investment
Company Act of 1940. Under the Rule, the Trustees must establish procedures
reasonably designed to stabilize the net asset value per share, as computed for
purposes of distribution and redemption, at $1.00 per share, taking into account
current market conditions and the Fund's investment objective. The procedures
include monitoring the relationship between the amortized cost value per share
and the net asset value per share based upon available indications of market
value. The Trustees will decide what, if any, steps should be taken if there is

- --------------------------------------------------------------------------------
a difference of more than 0.5 of 1% between the two values. The Trustees will
take any steps they consider appropriate (such as redemption in kind or
shortening the average portfolio maturity) to minimize any material dilution or
other unfair results arising from differences between the two methods of
determining net asset value.

REDEMPTION IN KIND
- --------------------------------------------------------------------------------

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

THE FUND'S TAX STATUS
- --------------------------------------------------------------------------------

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

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

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

YIELD

The Fund calculates its yield based upon the seven days ending on the day of the
calculation, called the "base period." This yield is computed by: determining
the net change in the value of a hypothetical account with a balance of one
share at the beginning of the base period, with the net change excluding capital
changes but including the value of any additional shares purchased with
dividends earned from the original one share and all dividends declared on the
original and any purchased shares; dividing the net change in the account's
value by the value of the account at the beginning of the base period to
determine the base period return; and multiplying the base period return by
365/7.

EFFECTIVE YIELD

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

TOTAL RETURN

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

PERFORMANCE COMPARISONS

Investors may use financial publications and/or indices to obtain a more
complete view of the Fund's performance. When comparing performance, investors
should consider all relevant factors such as the composition of any index used,
prevailing market conditions, portfolio compositions of other funds, and methods
used to

- --------------------------------------------------------------------------------
value portfolio securities and compute net asset value. The financial
publications and/or indices which the Fund uses in advertising may include:

      methods may vary.

PRIME OBLIGATIONS FUND
NOTES TO FINANCIAL STATEMENTS
JULY 31, 1993
- --------------------------------------------------------------------------------

(1) ORGANIZATION

Prime Obligations Fund (the "Fund") is a diversified portfolio and one of the
portfolios of Money Market Obligations Trust (the "Trust"), a no-load, open-end,
management investment company, which is registered under the Investment Company
Act of 1940, as amended. 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.

(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.

A.  INVESTMENT VALUATIONS--The Board of Trustees ("Trustees") has determined
    that the best method currently available for valuing portfolio securities is
    amortized cost. The Fund's use of the amortized cost method to value its
    portfolio securities is conditioned on its compliance with Rule 2a-7 under
    the Investment Company Act of 1940, as amended.

B.  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 in support of repurchase agreement
    investments. Additionally, procedures have been established by the Fund to
    monitor, on a daily basis, the market value of each repurchase agreement's
    underlying securities to ensure the existence of a proper level of
    collateral.

    The Fund will only enter into repurchase agreements with banks and other
    recognized financial institutions such as broker/dealers which are deemed by
    the Fund's adviser to be creditworthy pursuant to guidelines established by
    the Trustees. 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.

C.  INCOME--Interest income is recorded on the accrual basis. Interest income
    includes interest and discount earned (net of premium), including original
    issue discount as required by the Internal Revenue Code, plus realized net
    gains, if any, on portfolio securities.

D.  FEDERAL TAXES--It is the Fund's policy to comply with the provisions of the
    Internal Revenue Code applicable to investment companies and to distribute
    to shareholders each year all of its taxable income. Accordingly, no
    provision for federal tax is necessary.

E.  WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS--The Fund may engage in
    when-issued or delayed delivery transactions. To the extent the Fund engages
    in such transactions, it will do so for the purpose of acquiring portfolio
    securities consistent with its investment objective and policies and not for
    the purpose of investment leverage. The Fund will record a when-issued
    security and the related liability on the trade date. Until the securities
    are received and paid for, the Fund will maintain 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.

F.  DEFERRED EXPENSES--The costs incurred by the Fund with respect to
    registration of its shares in its first fiscal year, excluding the initial
    expenses of registering the shares, have been deferred and are being
    amortized using the straight-line method through December, 1994.

G.  OTHER--Investment transactions are accounted for on the date of the
    transaction.

(3) DIVIDENDS

The Fund computes its net income daily, and immediately prior to the calculation
of its net asset value at the close of business, declares and records dividends
to shareholders of record at the time of the previous computation of the Fund's
net asset value. Payment of dividends is made monthly in cash, or in additional
shares at the net asset value on the payable date.

(4) SHARES OF BENEFICIAL INTEREST

full and fractional shares of beneficial interest (without par value). At July
31, 1993, capital paid-in aggregated $1,098,159,186. Transactions in Fund shares

(5) INVESTMENT ADVISORY FEE AND OTHER TRANSACTIONS WITH AFFILIATES

Federated Management, the Fund's investment adviser ("Adviser"), receives for
its services an annual investment advisory fee equal to 0.20 of 1% of the Fund's
average daily net assets. For the year ended July 31, 1993, the Adviser
voluntarily agreed to waive the amount, limited to the amount of the advisory
fee, by which the Fund's aggregate annual operating expenses (including its
investment advisory fee but excluding interest, taxes, brokerage commissions,
insurance premiums, and extraordinary expenses) exceed 0.20 of 1% of its average
daily net assets. This does not include reimbursement to the Fund of any
expenses incurred by shareholders who use the transfer agent's subaccounting
facilities. The Adviser can terminate this voluntary agreement at any time in
its sole discretion. For the year ended July 31, 1993, the Adviser earned an
investment advisory fee of $2,033,502 of which $955,268 was voluntarily waived
in accordance with such agreement.

Federated Services Company, the Fund's recordkeeper, received for its services a
fee of $125,198 for the year ended July 31, 1993.

Administrative personnel and services were provided at approximate cost by
Federated Administrative Services, Inc. Certain Officers and Trustees of the
Trust are Officers and Directors of the above corporations.

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, 1993, and 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 (see page 2 of this prospectus)
for each of the three years in the period then ended and for the period from
March 26, 1990 (date of initial public investment) to July 31, 1990. 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 the securities owned as of
July 31, 1993, 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, 1993, 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 each of the three years in the period then
ended and for the period from March 26, 1990 (date of initial public investment)
to July 31, 1990, in conformity with generally accepted accounting principles.

APPENDIX
- --------------------------------------------------------------------------------

                       CORPORATE BOND RATING DEFINITIONS

STANDARD AND POOR'S CORPORATION

AAA--Debt rated AAA has the highest rating assigned by Standard & Poor's
Corporation. Capacity to pay interest and repay principal is extremely strong.
AA-Debt rated AA has a very strong capacity to pay interest and repay principal
and differs from the higher rated issues only in small degree. A-Debt rated A
has a strong capacity to pay interest and repay principal although it is
somewhat more susceptible to the adverse effect of changes in circumstances and
economic conditions than debt in higher rated categories.

MOODY'S INVESTORS SERVICE, INC.

AAA--Bonds which are rated AAA are judged to be of the best quality. They carry
the smallest degree of investment risk and are generally referred to as "gilt
edge." Interest payments are protected by a large or by an exceptionally stable
margin and principal is secure. While the various protective elements are likely
to change, such changes as can be visualized are most unlikely to impair the
fundamentally strong position of such issues. AA-Bonds which are rated AA are
judged to be of high quality by all standards. Together with the AAA group, they
comprise what are generally known as high grade bonds. They are rated lower than
the best bonds because margins of protection may not be as large as in AAA
securities or fluctuation of protective elements may be of greater amplitude or
there may be other elements present which make the long-term risks appear
somewhat larger than in AAA securities. A-Bonds which are rated A possess many
favorable investment attributes and are to be considered as upper medium grade
obligations. Factors giving security to principal and interest are considered
adequate but elements may be present which suggest a susceptibility to
impairment sometime in the future.

                       COMMERCIAL PAPER RATING DEFINITIONS
STANDARD & POOR'S CORPORATION

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

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

MOODY'S INVESTORS SERVICE, INC.

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

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

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

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

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

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

     accruing  the 12b-1  fee during  the period  ending July  31, 1994.  If the
     Institutional Service Shares  were paying  or accruing the  12b-1 fee,  the
     Class  would be able to pay up to 0.25% of its average daily net assets for
     the 12b-1 fee. See "Trust Information".
(3)  The Total Institutional Service Shares Operating Expenses are estimated  to
     be  0.59%  absent the  anticipated  voluntary waiver  of  a portion  of the
     management fee.
*   Total Institutional Service  Shares Expenses are estimated based on  average
expenses  expected to be incurred during the period ending July 31, 1994. During
the course of this period, expenses may be more or less than the average  amount
shown.

    The information set forth in the foregoing table and example relates only to
Institutional Service Shares of the Fund. The Fund also offers another class  of
shares   called   Institutional   Shares.  Institutional   Service   Shares  and
Institutional Shares  are subject  to  certain of  the same  expenses;  however,
Institutional  Shares are  not subject  to a  12b-1 fee.  See "Other  Classes of
Shares."

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 of beneficial interest 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 ("Shares") of the Fund, which are  designed
primarily  for financial institutions  as a convenient  means of accumulating an
interest  in  a  professionally  managed,  diversified  portfolio  investing  in
short-term  money market securities. A minimum  initial investment of $25,000 is
required.

Eligibility  for  investment  in  the  Fund  is  contingent  upon  an   investor
accumulating  and maintaining a minimum  aggregate investment of $200,000,000 in
Federated funds within a twelve-month period.  For this purpose, 1) an  investor
is  defined as  a financial institution  or its  collective customers, including
affiliate financial  institutions  and  their  collective  customers,  or  other
institutions  that are determined to qualify  by Federated Securities Corp., and
2) Federated funds  are those mutual  funds which are  distributed by  Federated
Securities  Corp., or are  advised by or administered  by investment advisers or
administrators affiliated with Federated  Securities Corp. ("Federated  Funds").
An  investor's minimum investment  will be calculated  by combining all accounts
the investor maintains with the Federated Funds, which includes the Trust.

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  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, 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;

    - construction  loan notes insured by the Federal Housing Administration and
      financed by the Federal or Government National Mortgage Associations; 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 an 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.   The Fund may  purchase municipal securities  in the form  of
participation  interests that  represent an  undivided proportional  interest in
lease payments by  a governmental or  nonprofit entity. The  lease payments  and
other   rights  under  the  lease  provide   for  and  secure  payments  on  the
certificates. Lease  obligations may  be  limited by  municipal charter  or  the
nature of the appropriation for the lease. Furthermore, a lease may provide that
the participants cannot

accelerate  lease obligations upon default. The  participants would only be able
to enforce lease  payments as  they became  due. In the  event of  a default  or
failure   of  appropriation,  unless  the  participation  interests  are  credit
enhanced, it  is unlikely  that the  participants  would be  able to  obtain  an
acceptable substitute source of payment.

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  Corporation ("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.

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

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

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 net assets.

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.

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.

    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.

    the  financial industry.  Federated Investors'  track record  of competitive
    performance and  its disciplined,  risk averse  investment philosophy  serve
    approximately  3,500  client  institutions  nationwide.  Through  these same
    client institutions, individual shareholders also  have access to this  same
    level of investment expertise.

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.

DISTRIBUTION AND SHAREHOLDER SERVICES PLANS.  Under a distribution plan  adopted
in  accordance with Investment Company Act Rule 12b-1 (the "Distribution Plan"),
the Fund will pay to  the distributor an amount, computed  at an annual rate  of
.25  of 1%  of the average  daily net  asset value of  the Institutional Service
Shares to finance any  activity which is principally  intended to result in  the
sale  of shares  subject to  the Distribution  Plan. The  distributor may select
financial institutions such as banks, fiduciaries, custodians for public  funds,
investment  advisers, and  broker/dealers to  provide sales  support services as
agents for  their clients  or customers.  In addition,  the Fund  has adopted  a
Shareholder  Services  Plan  (the  "Services  Plan")  under  which  it  will pay
financial institutions an

amount not exceeding  .25 of  1% of  the average daily  net asset  value of  the
Institutional Service Shares to provide administrative support services to their
customers  who own shares of the Fund. From time to time and for such periods as
deemed appropriate,  the  amounts  stated  above  may  be  reduced  voluntarily.
Activities  and  services  under these  arrangements  may include,  but  are not
limited  to,  providing  advertising  and  marketing  materials  to  prospective
shareholders,  providing  personal  services  to  shareholders,  and maintaining
shareholder accounts.

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 or  the
distributor, as appropriate.

The  Distribution Plan is a  compensation-type plan. As such,  the Fund makes no
payments to the distributor except as described above. Therefore, the Fund  does
not pay for unreimbursed expenses of the distributor, including amounts expended
by  the distributor in excess of amounts received by it from the Fund, interest,
carrying or other financing charges in connection with excess amounts  expended,
or  the distributor's overhead expenses. However, the distributor may be able to
recover such amounts or may earn a profit from future payments made by the  Fund
under the Distribution Plan.

Federated Investors,  provides  certain 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
which  relates to the average aggregate daily  net assets of all Federated Funds

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

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

the  Shares.  However, the  Board  of Trustees  reserves  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;

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  at 12:00  noon, 3:00  p.m., and  4:00  p.m.
(Boston  time) Monday through Friday except on:  (i) days on which there are not
sufficient changes in the value of the Fund's portfolio securities that its  net
asset  value might be materially affected; (ii)  days during which no shares are
tendered for redemption and no orders to purchase shares are received; or  (iii)
the  following holidays: New Year's Day,  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.,
(Boston time) to place an order.  The order is considered received  immediately.
Payment  by federal funds must be received  before 3:00 p.m., (Boston time) that
day. Federal  funds should  be wired  as follows:  State Street  Bank and  Trust
Company,  Boston, Massachusetts;  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

8602,  Boston, Massachusetts 02266-8602. 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 initial  investment is  $25,000. Eligibility for  investment in  the
Fund  is  contingent upon  an investor  accumulating  and maintaining  a minimum
aggregate investment of  $200,000,000 in Federated  Funds within a  twelve-month
period.

SUBACCOUNTING SERVICES

Financial  institutions are encouraged to  open single master accounts. However,
certain  financial  institutions   may  wish   to  use   the  transfer   agent's
subaccounting  system to minimize their internal recordkeeping requirements. The
transfer agent  charges a  fee  based on  the  level of  subaccounting  services
rendered.  Financial institutions may charge  or pass through subaccounting fees
as part of or in addition to normal trust or agency account fees. They may  also
charge fees for other services provided which may be related to the ownership of
Fund  shares.  This  prospectus should,  therefore,  be read  together  with any
agreement between the customer and the financial institution with regard to  the
services  provided, the fees charged for those services and any restrictions and
limitations imposed.

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. Shares purchased by wire  before
3:00  p.m. (Boston time)  begin earning dividends that  day. Shares purchased by
check begin  earning dividends  on the  day after  the check  is converted  into
federal  funds.  Dividends  are automatically  reinvested  in  additional Shares
unless cash payments are requested by contacting the Fund.

CAPITAL GAINS

Capital gains, if any, could result in an increase in dividends. Capital  losses
could  result in a decrease in dividends. If, for some extraordinary reason, the
Fund realizes net long-term capital gains, it will distribute them at least once
every 12 months.

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

Shares are redeemed  at their  net asset value  next determined  after the  Fund
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, P.O.  Box  8602, Boston,  Massachusetts  02266-8602. 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 certified mail with the written request. Shareholders requesting a
redemption of $50,000  or more,  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 firm 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 its 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. If  the redemption request  is
received  before 12:00 noon (Boston  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  (Boston time).  However, the
proceeds are not wired until the following business day.

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. Telephone redemption instructions  may
be recorded.

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.

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

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 $25,000 or the aggregate
investment  in Federated Funds falls below  the required minimum of $200,000,000
to be  maintained from  and after  twelve months  from account  opening, 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 June  28, 1994, Var  & Co.,  St. Paul, Minnesota,
owned 25.7%  of the  voting securities  of  the Fund,  and, therefore,  may  for
certain purposes be deemed to control the Fund and be able to affect the outcome
of certain matters presented for a vote of shareholders.
    

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.

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 Fund:

    - the Fund is  not subject  to Pennsylvania corporate  or personal  property
      taxes; and

    - 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.

STATE AND LOCAL TAXES

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

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

From   time  to  time  the  Fund  advertises  its  yield,  effective  yield  and
tax-equivalent yield for 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 Shares' 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.

The performance figures will be calculated separately for each class of  shares.
Because  each  class of  shares  is subject  to  different expenses,  the yield,
effective yield, and  tax-equivalent yield of  Institutional Shares will  exceed
the  yield, effective  yield and  tax-equivalent yield  of Institutional Service
Shares for the same period.

From time  to  time,  the  Fund may  advertise  its  performance  using  certain
financial publications and/or compare its performance to certain indices.

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

Institutional Shares are sold at net asset value to accounts for which financial
institutions   act  in   an  agency   or  fiduciary   capacity.  Investments  in
Institutional Shares are  subject to  a minimum initial  investment of  $25,000.
Institutional Shares are not sold pursuant to a 12b-1 Plan.

Financial  institutions  providing distribution  or administrative  services may
receive different compensation depending upon which class of shares of the  Fund
is sold. The amount of dividends payable to shareholders of Institutional Shares
will  exceed that payable to the shareholders of Institutional Service Shares by
the difference  between class  expenses and  any 12b-1  Plan expenses  borne  by
Institutional  Service  Shares. The  stated advisory  fee is  the same  for both
classes of shares.

INVESTMENT POLICIES
- --------------------------------------------------------------------------------

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

CHARACTERISTICS OF MUNICIPAL SECURITIES.

When determining whether a municipal security presents minimal credit risks, the
investment adviser will consider the creditworthiness of: the issuer of a
municipal security, the issuer of a demand feature if the Fund has the
unconditional right to demand payment for the municipal security, or any
guarantor of payment by either of those issuers.

The Fund is not required to sell a municipal security if the security's rating
is reduced below the required minimum subsequent to the Fund's purchase of the
security. The investment adviser considers this event, however, in its
determination of whether the Fund should continue to hold the security in its
portfolio. If ratings made by Moody's Investors Service, Inc. ("Moody's"),
Standard & Poor's Corporation ("S&P") or Fitch Investors Service, Inc. ("Fitch")
change because of changes in those organizations or in their rating systems, the
Fund will try to use comparable ratings as standards in accordance with the
investment policies described in the Fund's prospectus.

MUNICIPAL LEASES

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

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

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

The Fund may also sell municipal securities on a delayed delivery basis with
settlement taking place more than five days after the sale as a normal form of
portfolio transaction. It is the investment adviser's experience that it is not
unusual in the municipal securities market for settlement periods to be slightly
longer than this period.

TEMPORARY INVESTMENTS

The Fund may also invest in high quality, temporary investments from time to
time for temporary defensive purposes.

                                                                               1
- --------------------------------------------------------------------------------

    REPURCHASE AGREEMENTS

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

INVESTMENT RISKS

Litigation or legislation could affect the validity of certain municipal
securities or their tax-free interest. For example, litigation challenging the
validity of systems of financing public education has been initiated or
adjudicated in a number of states. The Fund will not investigate such
legislation or litigation unless it deems it necessary to do so. To the extent
that litigation or legislation has an adverse effect on the ratings ascribed to
a particular municipal security, there is some protection to the Fund's
shareholders from the Fund's policy of buying only high-rated securities.

INVESTMENT LIMITATIONS

    SELLING SHORT AND BUYING ON MARGIN

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

    ISSUING SENIOR SECURITIES AND BORROWING MONEY

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

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

    PLEDGING ASSETS

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

    LENDING CASH OR SECURITIES

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

    INVESTING IN COMMODITIES AND REAL ESTATE

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

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

    DIVERSIFICATION OF INVESTMENTS

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

      Under this limitation, each governmental subdivision, including states and
      the District of Columbia, territories, possessions of the United States,
      or their political subdivisions, agencies, authorities, instrumentalities,
      or similar entities, will be considered a separate issuer if its assets
      and revenues are separate from those of the governmental body creating it
      and the security is backed only by its own assets and revenues. If in the
      case of an industrial development bond or governmental-issued security, a
      governmental or other entity guarantees the security, such guarantee would
      be considered a separate security issued by the guarantor as well as the
      other issuer, subject to limited exclusions allowed by the Investment
      Company Act of 1940.

    CONCENTRATION OF INVESTMENTS

      The Fund will not purchase securities if, as a result of such purchase,
      25% or more of the value of its total assets would be invested in any one
      industry or in industrial development bonds or other securities, the
      interest upon which is paid from revenues of similar type projects.

      The Fund may invest, as temporary investments, 25% or more of the value of
      its total assets in cash or cash items, securities issued or guaranteed by
      the U.S. government, its agencies or instrumentalities or instruments
      secured by these money market instruments, such as repurchase agreements.

      The Fund does not intend to purchase securities that would increase the
      percentage of its assets invested in the securities of governmental
      subdivisions located in any one state, territory, or U.S. possession to
      25% or more. However, the Fund may invest 25% or more of the value of its
      assets in tax-exempt project notes guaranteed by the U.S. government,
      regardless of the location of the issuing municipality.

      If the value of Fund assets invested in the securities of a governmental
      subdivision changes because of changing values, the Fund will not be
      required to make any reduction in its holdings.

    UNDERWRITING

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

    INVESTING IN RESTRICTED SECURITIES

      The Fund will not invest more than 10% of the value of its net assets in
      securities which are subject to legal or contractual restrictions on
      resale.

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

    INVESTING IN ILLIQUID SECURITIES

      The Fund will not invest more than 10% of the value of its net assets in
      illiquid securities.

    INVESTING IN SECURITIES OF OTHER INVESTMENT COMPANIES

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

    INVESTING IN NEW ISSUERS

      The Fund will not invest more than 5% of the value of its total assets in
      securities of issuers (including companies responsible for paying
      principal and interest on industrial development bonds) which have records
      of less than three years of continuous operations, including the operation
      of any predecessor.

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

    INVESTING FOR CONTROL

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

    INVESTING IN ISSUERS WHOSE SECURITIES ARE OWNED BY OFFICERS OF THE TRUST

      The Fund will not purchase or retain the securities of any issuer if the
      Officers and Trustees of the Trust or its investment adviser owning
      individually more than .50 of 1% of the issuer's securities together own
      more than 5% of the issuer's securities.

    INVESTING IN OPTIONS

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

    INVESTING IN MINERALS

      The Fund will not purchase or sell interests in oil, gas, or other mineral
      exploration or development programs or leases, although it may purchase
      the securities of issuers which invest in or sponsor such programs.

For purposes of the above limitations, the Fund considers certificates of
deposit and demand and time deposits issued by a U.S. branch of a domestic bank
or savings and loan having capital, surplus, and undivided profits in excess of
$100,000,000 at the time of investment to be "cash items". Except with respect
to borrowing money, if a percentage limitation is adhered to at the time of
investment, a later increase or decrease in percentage resulting from any change
in value or net assets will not result in a violation of such limitation.

The Fund did not issue senior securities, pledge securities, invest in illiquid
securities, or engage in when-issued and delayed delivery transactions in excess
of 5% of the value of its net assets during the last fiscal period and has no
present intent to do so during the coming fiscal year.

BROKERAGE TRANSACTIONS
- --------------------------------------------------------------------------------

When selecting brokers and dealers to handle the purchase and sale of portfolio
instruments, the adviser looks for prompt execution of the order at a favorable
price. In working with dealers, the adviser will generally use those who are
recognized dealers in specific portfolio instruments, except when a better price
and execution of the order can be obtained elsewhere. The adviser makes
decisions on portfolio transactions and selects brokers and dealers subject to
guidelines established by the Board of Trustees. The adviser may select brokers
and dealers who offer brokerage and research services. These services may be
furnished directly to the Fund or to the adviser and may include: advice as to
the advisability of investing in securities; security analysis and reports;
economic studies; industry studies; receipt of quotations for portfolio
evaluations; and similar services. Research services provided by brokers and
dealers may be used by the adviser or its affiliates in advising the Trust and
other accounts. To the extent that receipt of these services may supplant
services for which the adviser or its affiliates might otherwise have paid, it
would tend to reduce their expenses. The adviser and its affiliates exercise
reasonable business judgment in selecting brokers who offer brokerage and
research services to execute securities transactions. They determine in good
faith that commissions charged by such persons are reasonable in relationship to
the value of the brokerage and research services provided. During the fiscal
year(s) ended July 31, 1993, 1992 and 1991, the Trust paid no brokerage
commissions.

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

against any liability to which they would otherwise be subject by reason of
willful misfeasance, bad faith, gross negligence, or reckless disregard of the
duties involved in the conduct of their office.

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

INVESTMENT ADVISORY SERVICES
- --------------------------------------------------------------------------------

INVESTMENT ADVISER(S)

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

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

ADVISORY FEES

For its advisory services, Federated Management receives an annual investment
advisory fee as described in the prospectus. For the fiscal years ended July 31,
1993, 1992 and 1991, the Fund's adviser earned $820,734, $469,718 and $295,082,
respectively for services provided on behalf of Institutional Shares, of which
$582,656, $402,871, and $295,082 were voluntarily waived because of undertakings
to limit the Fund's expenses.

    STATE EXPENSE LIMITATIONS

      The adviser has undertaken to comply with the expense limitations
      established by certain states for investment companies whose shares are
      registered for sale in those states.

      If the Fund's normal operating expenses (including the investment advisory
      fee, but not including brokerage commissions, interest, taxes, and
      extraordinary expenses) exceed 2 1/2% per year of the first $30 million of
      average net assets, 2% per year of the next $70 million of average net
      assets, and 1 1/2% per year of the remaining average net assets, the
      adviser will reimburse the Fund for its expenses over the limitation.

      If the Fund's monthly projected operating expenses exceed this limitation,
      the investment advisory fee paid will be reduced by the amount of the
      excess, subject to an annual adjustment. If the expense limitation is
      exceeded, the amount to be reimbursed by the adviser will be limited, in
      any single fiscal year, by the amount of the investment advisory fees.

      This arrangement is not part of the advisory contract and may be amended
      or rescinded in the future.

FUND ADMINISTRATION
- --------------------------------------------------------------------------------

Federated Administrative Services, a subsidiary of Federated Investors, provides
administrative personnel and services to the Trust for a fee as described in the
prospectus for each class of shares of the Fund. For the fiscal years ended July
31, 1993, 1992, and 1991, Federated Administrative Services, Inc., the Trust's
former administrator, earned $284,326, $210,978, and $214,524, respectively.
John A. Staley, IV, an officer of the Trust and Dr. Henry J. Gailliot, an
officer of Federated Management, the adviser to the Fund, each hold
approximately 15% and 20%, respectively, of the outstanding common stock of
Commercial Data Services, Inc., a company which provides computer processing
services to Federated Administrative Services, Inc., and Federated
Administrative Services. For the fiscal years ended December 31, 1993, 1992, and
1991, Federated Administrative Services, Inc. paid approximately $161,547,
$201,799, and $170,529, respectively for services provided by Commercial Data
Services, Inc., to the Funds.

SHAREHOLDER SERVICES PLAN
- --------------------------------------------------------------------------------

With respect to Institutional Service Shares the Fund has adopted a Shareholder
Services Plan. This arrangement permits the payment of fees to Federated
Shareholder Services and, indirectly to financial institutions to cause services
to be provided to shareholders by a representative who has knowledge of the
shareholder's particular circumstances and goals. These activities and services
may include, but are not limited to, providing office space, equipment,
telephone facilities, and various clerical, supervisory, computer, and other
personnel as necessary or beneficial to establish and maintain shareholder
accounts and records; processing purchase and redemption

- --------------------------------------------------------------------------------
transactions and automatic investments of client account cash balances;
answering routine client inquiries; and assisting clients in changing dividend
options, account designation, and addresses.

DISTRIBUTION PLAN
- --------------------------------------------------------------------------------

With respect to Institutional Service Shares the Fund has adopted a Plan
pursuant to Rule 12b-1 which was promulgated by the Securities and Exchange
Commission pursuant to the Investment Company Act of 1940. The Plan permits the
payment of fees to brokers for distribution and administrative services and to
administrators for administrative services. The Plan is designed to (i)
stimulate brokers to provide distribution and administrative support services to
shareholders and (ii) stimulate administrators to render administrative support
services to shareholders. The administrative services are provided by a
representative who has knowledge of the shareholder's particular circumstances
and goals. By adopting the Plan, the Board of Trustees expects that the Fund
will be able to achieve a more predictable flow of cash for investment purposes
and to meet redemptions. This will facilitate more efficient portfolio
management and assist the Fund in seeking to achieve its investment objectives.
By identifying potential investors whose needs are served by the Fund's
objectives, and properly servicing these accounts, it may be possible to curb
sharp fluctuations in rates of redemptions and sales. Other benefits may
include: (1) an efficient and effective administrative system; (2) a more
efficient use of shareholder assets by having them rapidly invested with a
minimum of delay and administrative detail; and (3) an efficient and reliable
shareholder records system and prompt responses to shareholder requests and
inquiries concerning their accounts.

CUSTODIAN AND PORTFOLIO RECORDKEEPER.  State Street Bank and Trust Company,
Boston, Massachusetts is custodian for the securities and cash of the Fund.
Federated Services Company, Pittsburgh, Pennsylvania provides certain accounting
and recordkeeping services with respect to the Fund's portfolio investments.

DETERMINING NET ASSET VALUE
- --------------------------------------------------------------------------------

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

The Fund's use of the amortized cost method of valuing portfolio instruments
depends on its compliance with certain conditions in Rule 2a-7 (the "Rule")
promulgated by the Securities and Exchange Commission under the Investment
Company Act of 1940. Under the Rule, the Trustees must establish procedures
reasonably designed to stabilize the net asset value per share, as computed for
purposes of distribution and redemption, at $1.00 per share, taking into account
current market conditions and the Fund's investment objective. The procedures
include monitoring the relationship between the amortized cost value per share
and the net asset value per share based upon available indications of market
value. The Trustees will decide what, if any, steps should be taken if there is
a difference of more than 0.5 of 1% between the two values. The Trustees will
take any steps they consider appropriate (such as redemption in kind or
shortening the average portfolio maturity) to minimize any material dilution or
other unfair results arising from differences between the two methods of
determining net asset value.

REDEMPTION IN KIND
- --------------------------------------------------------------------------------

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

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

THE FUND'S TAX STATUS
- --------------------------------------------------------------------------------

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

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

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

YIELD

The Fund calculates its yield based upon the seven days ending on the day of the
calculation, called the "base period." This yield is computed by: determining
the net change in the value of a hypothetical account with a balance of one
share at the beginning of the base period, with the net change excluding capital
changes but including the value of any additional shares purchased with
dividends earned from the original one share and all dividends declared on the
original and any purchased shares; dividing the net change in the account's
value by the value of the account at the beginning of the base period to
determine the base period return; and multiplying the base period return by
365/7.

EFFECTIVE YIELD

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

TAX-EQUIVALENT YIELD

The tax-equivalent yield of the Fund is calculated similarly to the yield, but
is adjusted to reflect the taxable yield that the Fund would have had to earn to
equal its actual yield, assuming a 39.6% tax rate (the maximum effective federal
rate for individuals and assuming that income is 100% exempt.

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

TAX-EQUIVALENCY TABLE

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

TOTAL RETURN

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

NOTES TO PORTFOLIO OF INVESTMENTS

                    SHORT-TERM MUNICIPAL OBLIGATION RATINGS

S&P

A Standard & Poor's note rating reflects the liquidity concerns and market
access risks unique to notes.

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

SP-2       Satisfactory capacity to pay principal and interest.
</TABLE>

MOODY'S

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

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

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

                                      AND
                           TENDER OPTION BONDS (TOBS)
                                    RATINGS

S&P

Standard & Poor's assigns dual ratings to all long-term debt issues that have as
part of their provisions a variable rate demand feature. The first rating
(long-term rating) addresses the likelihood of repayment of principal and
interest when due, and the second rating (short-term rating) describes the
demand characteristics. Several examples are AAA/A-1+, AA/A-1+, and A/A-1. (The
definitions for the long-term and the short-term ratings are provided below.)

MOODY'S

Short-term ratings on issues with demand features are differentiated by the use
of the VMIG symbol to reflect such characteristics as payment upon periodic
demand rather than fixed maturity dates and payment relying on external
liquidity.

In this case, two ratings are usually assigned, (for example, Aaa/VMIG-1), with
the first representing an evaluation of the degree of risk associated with
scheduled principal and interest payments, and the second representing an
evaluation of the degree of risk associated with the demand feature. The VMIG
rating can be assigned a 1 or 2 designation using the same definitions described
above for the MIG rating.

                         COMMERCIAL PAPER (CP) RATINGS

S&P

A Standard & Poor's commercial paper rating is a current assessment of the
likelihood of timely payment of debt having an original maturity of no more than
365 days.

<TABLE>
<S>        <C>
A-1        This  designation  indicates  that  the  degree  of  safety  regarding  timely  payment  is  either
           overwhelming or very strong. Those issues determined to possess overwhelming safety characteristics
           are denoted with a plus (+) designation.

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

MOODY'S
P-1        Issuers  rated Prime-1 (or related supporting institutions)  have a superior capacity for repayment
           of short-term promissory obligations.
</TABLE>

TAX-FREE OBLIGATIONS FUND

<S>        <C>
P-2        Issuers rated Prime-2 (or related supporting institutions) have a strong capacity for repayment  of
           short-term promissory obligations.

                                            LONG-TERM DEBT RATINGS

S&P

AAA        Debt rated "AAA" has the highest rating assigned by Standard & Poor's. Capacity to pay interest and
           repay principal is extremely strong.

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

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

MOODY'S

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

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

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

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

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

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

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

TAX-FREE OBLIGATIONS FUND
NOTES TO FINANCIAL STATEMENTS
JULY 31, 1993
- --------------------------------------------------------------------------------

(1) ORGANIZATION

Tax-Free Obligations Fund (the "Fund") is a diversified portfolio and one of the
portfolios of Money Market Obligations Trust (the "Trust"), a no-load, open-end,
management investment company, which is registered under the Investment Company
Act of 1940, as amended. 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.

(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.

A.  INVESTMENT VALUATIONS--The Board of Trustees ("Trustees") has determined
    that the best method currently available for valuing portfolio securities is
    amortized cost. The Fund's use of the amortized cost method to value its
    portfolio securities is conditioned on its compliance with Rule 2a-7 under
    the Investment Company Act of 1940, as amended.

B.  INCOME--Interest income is recorded on the accrual basis. Interest income
    includes interest earned net of premium, and original issue discount as
    required by the Internal Revenue Code.

C.  FEDERAL TAXES--It is the Fund's policy to comply with the provisions of the
    Internal Revenue Code applicable to investment companies and to distribute
    to shareholders each year all of its taxable income. Accordingly, no
    provision for federal tax is necessary. Dividends paid by the Fund
    representing net interest received on tax-exempt municipal securities are
    not includable by shareholders as gross income for federal regular tax
    purposes because the Fund intends to meet certain requirements of the
    Internal Revenue Code applicable to regulated investment companies which
    will enable the Fund to pay tax-exempt interest dividends. The portion of
    such interest, if any, earned on private activity bonds issued after August
    7, 1986 may be considered a tax preference item to shareholders.

D.  WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS--The Fund may engage in
    when-issued or delayed delivery transactions. To the extent the Fund engages
    in such trasnactions, it will do so for the purpose of acquiring portfolio
    securities consistent with its investment objective and policies and not for
    the purpose of investment leverage. The Fund will record a when-issued
    security and the related liability on the trade date. Until the securities
    are received and paid for, the Fund will maintain 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.

E.  DEFERRED EXPENSES--The costs incurred by the Fund with respect to
    registration of its shares in its firsts fiscal year, excluding the initial
    expenses of registering the shares, have been deferred and are being
    amortized using the straight-line method through December, 1994.

F.  OTHER--Investment transactions are accounted for on the date of the
    transaction.

(3) DIVIDENDS

The Fund computes its net income daily and, immediately prior to the calculation
of its net asset value at the close of business, declares and records dividends
to shareholders of record at the time of the previous computation of the Fund's
net asset value. Payment of dividends is made monthly in cash, or in additional
shares at the net asset value on the payable date.

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

(4) SHARES OF BENEFICIAL INTEREST

full and fractional shares of beneficial interest (without par value). At July
31, 1993, capital paid-in aggregated $454,142,623. Transactions in Fund shares

(5) INVESTMENT ADVISORY FEE AND OTHER TRANSACTIONS WITH AFFILIATES

Federated Management, the Fund's investment adviser ("Adviser"), receives for
its services an annual investment advisory fee equal to 0.20 of 1% of the Funds
average daily net assets. For the year ended July 31, 1993, the Adviser
voluntarily agreed to waive the amount, limited to the amount of the advisory
fee, by which the Fund's aggregate annual operating expenses (including its
investment advisory fee but excluding interest, taxes, brokerage commissions,
insurance premiums, and extraordinary expenses) exceed 0.20 of 1% of its average
daily net assets. This does not include reimbursement to the Fund of any
expenses incurred by shareholders who use the transfer agent's subaccounting
facilities. The Adviser can terminate this voluntary agreement at any time in
its sole discretion. For the year ended July 31, 1993, the Adviser earned an
investment advisory fee of $820,734 of which $582,656 was voluntarily waived in
accordance with such agreement.

During the fiscal year ended July 31, 1993, the Fund engaged in purchase and
sale transactions with other funds advised by the Adviser pursuant to Rule 17a-7
of the Investment Company Act of 1940, as amended, amounting to $632,525,000 and
$696,725,000, respectively. These purchases and sales were conducted on an
arms-length basis insofar as they were transacted for cash consideration only,
at independent current market prices and without brokerage commission, fee or
other remuneration.

Federated Services Company, Pittsburgh, Pennsylvania, assumed the role of the
Fund's recordkeeper, as of August 1, 1992. For the fiscal year ended July 31,
1993, Federated Services Company received for its services a fee of $72,752.

Administrative personnel and services were provided at approximate cost by
Federated Administrative Services, Inc. Certain Officers and Trustees of the
Trust are Officers and Directors of the above corporations.

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, 1993, and 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 (see page 2 of the prospectus)
for each of the three years in the period then ended and for the period from
December 12, 1989 (date of initial public investment) to July 31, 1990. These
financial statements and financial highlights are the responsibility of the
Trusts 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 the securities owned as of
July 31, 1993, 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
Tax-Free Obligations Fund (an investment portfolio of Money Market Obligations
Trust) as of July 31, 1993, 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 each of the three years in the
period then ended and for the period from December 12, 1989 (date of initial
public investment) to July 31, 1990, 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 of beneficial interest 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 ("Shares") of the Fund, which are designed
primarily for financial institutions  as a convenient  means of accumulating  an
interest  in  a  professionally  managed,  diversified  portfolio  investing  in
short-term money market securities. A  minimum initial investment of $25,000  is
required.

Eligibility   for  investment  in  the  Fund  is  contingent  upon  an  investor
accumulating and maintaining a minimum  aggregate investment of $200,000,000  in
Federated  funds within a twelve-month period.  For this purpose, 1) an investor
is defined as  a financial  institution or its  collective customers,  including
affiliate  financial  institutions  and  their  collective  customers,  or other
institutions that are determined to  qualify by Federated Securities Corp.,  and
2)  Federated funds  are those mutual  funds which are  distributed by Federated
Securities Corp., or are  advised by or administered  by investment advisers  or
administrators  affiliated with Federated  Securities Corp. ("Federated Funds").
An investor's minimum investment  will be calculated  by combining all  accounts
the investor maintains with the Federated Funds, which includes the Trust.

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

INVESTMENT INFORMATION
- --------------------------------------------------------------------------------

INVESTMENT OBJECTIVE

The investment objective of the Fund is current income consistent with stability
of principal. This  investment objective cannot  be changed without  shareholder
approval.  While there is no assurance that the Fund will achieve its investment
objective, it endeavors to do so by 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.
They mature in 13 months  or less from the date  of acquisition unless they  are
purchased under a repurchase agreement that provides for

repurchase  by the seller within one year from the date of acquisition. The Fund
may also purchase these instruments on a when-issued or delayed delivery basis.

REPURCHASE AGREEMENTS.   Certain securities  in which  the Fund  invests may  be
purchased   pursuant  to   repurchase  agreements.   Repurchase  agreements  are
arrangements in  which banks,  brokers/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.

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.  Total  assets  under  management   or
    administration  by these and  other subsidiaries of  Federated Investors are
    approximately $70 billion. Federated Investors, which was founded in 1956 as
    Federated Investors, Inc., develops and  manages mutual funds primarily  for
    the  financial industry.  Federated Investors'  track record  of competitive
    performance and  its disciplined,  risk averse  investment philosophy  serve
    approximately  3,500  client  institutions  nationwide.  Through  these same
    client institutions, individual shareholders also  have access to this  same
    level of investment expertise.

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.

DISTRIBUTION AND SHAREHOLDER SERVICES PLANS.  Under a distribution plan  adopted
in  accordance with Investment Company Act Rule 12b-1 (the "Distribution Plan"),
the Fund will pay to  the distributor an amount, computed  at an annual rate  of
.25  of 1%  of the average  daily net  asset value of  the Institutional Service
Shares to finance any  activity which is principally  intended to result in  the
sale  of shares  subject to  the Distribution  Plan. The  distributor may select
financial institutions such as banks, fiduciaries, custodians for public  funds,
investment  advisers, and  broker/dealers to  provide sales  support services as
agents for  their clients  or customers.  In addition,  the Fund  has adopted  a
Shareholder  Services  Plan  (the  "Services  Plan")  under  which  it  will pay
financial institutions an amount  not exceeding .25 of  1% of the average  daily
net  asset value of  the Institutional Service  Shares to provide administrative
support services  to their  customers who  own  shares of  the Fund.  From  time

to time and for such periods as deemed appropriate, the amounts stated above may
be  reduced voluntarily.  Activities and  services under  these arrangements may
include, but are not limited  to, providing advertising and marketing  materials
to  prospective shareholders,  providing personal services  to shareholders, and
maintaining shareholder accounts.

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 or  the
distributor, as appropriate.

The  Distribution Plan is a  compensation-type plan. As such,  the Fund makes no
payments to the distributor except as described above. Therefore, the Fund  does
not pay for unreimbursed expenses of the distributor, including amounts expended
by  the distributor in excess of amounts received by it from the Fund, interest,
carrying or other financing charges in connection with excess amounts  expended,
or  the distributor's overhead expenses. However, the distributor may be able to
recover such amounts or may earn a profit from future payments made by the  Fund
under the Distribution Plan.

ADMINISTRATION OF THE FUND

ADMINISTRATIVE  SERVICES.   Federated Administrative  Services, a  subsidiary of
Federated Investors,  provides  certain 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
which  relates to the average aggregate daily  net assets of all Federated Funds
as specified below:

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  allocated to the Shares  as a class are expenses
under the Fund's Rule 12b-1 Plan  and Shareholder Services Plan which relate  to
the  Shares.  However, the  Board  of Trustees  reserves  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  at 12:00  noon, 3:00  p.m., and  4:00  p.m.
(Boston  time) Monday through Friday except on:  (i) days on which there are not
sufficient changes in the value of the Fund's portfolio securities that its  net
asset  value might be materially affected; (ii)  days during which no shares are
tendered for redemption and no orders to purchase shares are received; or  (iii)
the  following holidays: New Year's Day,  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.,
(Boston  time) to place an order.  The order is considered received immediately.
Payment by federal funds must be  received before 3:00 p.m., (Boston time)  that
day.  Federal funds  should be  wired as  follows: State  Street Bank  and Trust
Company, Boston,  Massachusetts; 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.

BY MAIL.  To purchase by mail, send a check made payable to Treasury Obligations
Fund  -- Institutional  Service Shares to:  Treasury Obligations  Fund, P.O. Box
8602, Boston, Massachusetts 02266-8602. 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 initial  investment is $25,000.  Eligibility for  investment in the
Fund is  contingent upon  an  investor accumulating  and maintaining  a  minimum
aggregate  investment of $200,000,000  in Federated Funds  within a twelve-month
period.

SUBACCOUNTING SERVICES

Financial institutions are encouraged to  open single master accounts.  However,
certain   financial  institutions   may  wish   to  use   the  transfer  agent's
subaccounting system to minimize their internal recordkeeping requirements.  The
transfer  agent  charges a  fee  based on  the  level of  subaccounting services
rendered. Financial institutions may charge  or pass through subaccounting  fees
as  part of or in addition to normal trust or agency account fees. They may also
charge fees for other services provided which may be related to the ownership of
Fund shares.  This  prospectus should,  therefore,  be read  together  with  any
agreement  between the customer and the financial institution with regard to the
services provided, the fees charged for those services and any restrictions  and
limitations imposed.

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. Shares purchased by wire before
3:00 p.m. (Boston time)  begin earning dividends that  day. Shares purchased  by
check  begin earning  dividends on  the day  after the  check is  converted into
federal funds.  Dividends  are  automatically reinvested  in  additional  Shares
unless cash payments are requested by contacting the Fund.

CAPITAL GAINS

Capital  Gains, if any, could result in an increase in dividends. Capital losses
could result in a decrease in dividends. If, for some extraordinary reason,  the
Fund realizes net long-term capital gains, it will distribute them at least once
every 12 months.

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

Shares  are redeemed  at their  net asset value  next determined  after the Fund
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,  P.O.  Box 8602,  Boston,  Massachusetts 02266-8602.  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 certified mail with the written request.

Shareholders requesting a  redemption of $50,000  or more, 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 firm 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 its 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. If the  redemption request is
received before 12:00 noon  (Boston 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 (Boston  time). However,  the
proceeds  are  not  wired  until  the  following  business  day.  Under  limited
circumstances, arrangements  may  be  made with  the  distributor  for  same-day
payment  of  proceeds,  without  that day's  dividend,  for  redemption requests
received before 3:00 p.m., (Boston time).

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. Telephone redemption instructions  may
be recorded.

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.

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

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 $25,000 or the aggregate
investment  in Federated Funds falls below  the required minimum of $200,000,000
to be  maintained from  and after  twelve months  from account  opening, 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 applicable to regulated investment companies and to
receive the special tax treatment afforded to such companies.

The  Fund will be  treated as a  single, separate entity  for federal income tax
purposes so that  income (including capital  gains) and losses  realized by  the
Trust's  other  portfolios will  not  be combined  for  tax purposes  with those
realized by the Fund.

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

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

PENNSYLVANIA CORPORATE AND PERSONAL PROPERTY TAXES

In the opinion of Houston, Houston & Donnelly, counsel to the Fund:

    - the Fund is  not subject  to Pennsylvania corporate  or personal  property
      taxes; and

    - 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.

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

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

Yield  represents the annualized rate  of income earned on  an investment over a
seven-day period. It is then 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.

Performance  figures will  be calculated  separately for  each class  of shares.
Because each class of shares is  subject to different expenses, the  performance
of   Institutional  Shares  will  exceed  the   yield  and  effective  yield  of
Institutional Service Shares for the same period.

From time  to  time,  the  Fund may  advertise  its  performance  using  certain
financial publications and/or compare its performance to certain indices.

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

Institutional Shares are sold at net asset value to accounts for which financial
institutions   act  in   an  agency   or  fiduciary   capacity.  Investments  in
Institutional Shares are  subject to  a minimum initial  investment of  $25,000.
Institutional Shares are not sold pursuant to a 12b-1 Plan.

Financial  institutions  providing distribution  or administrative  services may
receive different compensation depending upon which class of shares of the  Fund
is sold. The amount of dividends payable to shareholders of Institutional Shares
will  exceed that payable to the shareholders of Institutional Service Shares by
the difference  between class  expenses and  any 12b-1  Plan expenses  borne  by
Institutional  Service  Shares. The  stated advisory  fee is  the same  for both
classes of shares.

*  Reflects operations for the period from February 23, 1990 (date of initial public investment) to July 31, 1990.
   For the period from the start of business, November 16, 1989, to February 22, 1990, net investment income
   aggregating $.014753 per share ($1,475) was distributed to the Fund's adviser. Such distribution represented the
   net income of the fund prior to the date of initial public investment, February 23, 1990.
(a) Computed on an annualized basis.
(b) For the fiscal years ended July 31, 1993, 1992, and 1991, and the period from the date of initial public
    investment, February 23, 1990, to July 31, 1990, the investment adviser voluntarily waived all or a portion of
    its fee. Had the adviser not undertaken such action, the ratios of expenses and net investment income to average
    net assets would have been 0.27% and 3.04%, 0.28% and 4.41%, 0.29% and 6.56%, and 0.35% and 8.01%, respectively,
    on an annualized basis.

INVESTMENT POLICIES
- --------------------------------------------------------------------------------

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

WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS

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

REPURCHASE AGREEMENTS

The Fund or its custodian will take possession of the securities subject to
repurchase agreements, and these securities will be marked to market daily. In
the event that a defaulting seller filed for bankruptcy or became insolvent,
disposition of such securities by the Fund might be delayed pending court
action. The Fund believes that under the regular procedures normally in effect
for custody of the Fund's portfolio securities subject to repurchase agreements,
a court of competent jurisdiction would rule in favor of the Fund and allow
retention or disposition of such securities. The Fund will only enter into
repurchase agreements with banks and other recognized financial institutions,
such as broker/dealers, which are deemed by the Fund's adviser to be
creditworthy pursuant to guidelines established by the Trustees.

INVESTMENT LIMITATIONS
- --------------------------------------------------------------------------------

SELLING SHORT AND BUYING ON MARGIN

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

ISSUING SENIOR SECURITIES AND BORROWING MONEY

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

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

PLEDGING ASSETS

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

LENDING CASH OR SECURITIES

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

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

INVESTING IN COMMODITIES

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

INVESTING IN REAL ESTATE

The Fund will not purchase or sell real estate, including limited partnership
interests.

UNDERWRITING

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

CONCENTRATION OF INVESTMENTS

The Fund will not invest 25% or more of the value of its total assets in any one
industry, except that the Fund may invest 25% or more of the value of its total
assets in cash, cash items, or securities issued or guaranteed by the government
of the United States or its agencies, or instrumentalities and repurchase
agreement collateralized by such U.S. government securities.

DIVERSIFICATION OF INVESTMENTS

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

INVESTING IN RESTRICTED SECURITIES

The Fund will not invest in securities subject to restrictions on resale under
federal securities law.

INVESTING IN ILLIQUID SECURITIES

The Fund will not invest more than 10% of the value of its net assets in
illiquid securities.

INVESTING IN SECURITIES OF OTHER INVESTMENT COMPANIES

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

INVESTING IN NEW ISSUERS

The Fund will not invest more than 5% of the value of its total assets in
securities of issuers which have records of less than three years of continuous
operations, including the operation of any predecessor.

INVESTING FOR CONTROL

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

INVESTING IN ISSUERS WHOSE SECURITIES ARE OWNED BY OFFICERS OF THE TRUST

The Fund will not purchase or retain the securities of any issuer if the
Officers and Trustees of the Trust or its investment adviser owning individually
more than .50 of 1% of the issuer's securities together own more than 5% of the
issuer's securities.

INVESTING IN OPTIONS

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

INVESTING IN MINERALS

The Fund will not purchase or sell interests in oil, gas, or other mineral
exploration or development programs or leases, although it may purchase the
securities of issuers which invest in or sponsor such programs.

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

- --------------------------------------------------------------------------------
percentage limitation is adhered to at the time of investment, a later increase
or decrease in percentage resulting from any change in value or net assets will
not result in a violation of such limitation.

The Fund did not issue senior securities, pledge securities, invest in illiquid
securities, or engage in when issued and delayed delivery transactions in excess
of 5% of the value of its net assets during the last fiscal period and has no
present intent to do so during the coming fiscal year.

BROKERAGE TRANSACTIONS
- --------------------------------------------------------------------------------

When selecting brokers and dealers to handle the purchase and sale of portfolio
instruments, the adviser looks for prompt execution of the order at a favorable
price. In working with dealers, the adviser will generally use those who are
recognized dealers in specific portfolio instruments, except when a better price
and execution of the order can be obtained elsewhere. The adviser makes
decisions on portfolio transactions and selects brokers and dealers subject to
guidelines established by the Board of Trustees. The adviser may select brokers
and dealers who offer brokerage and research services. These services may be
furnished directly to the Fund or to the adviser and may include: advice as to
the advisability of investing in securities; security analysis and reports;
economic studies; industry studies; receipt of quotations for portfolio
evaluations; and similar services. Research services provided by brokers and
dealers may be used by the adviser or its affiliates in advising the Trust and
other accounts. To the extent that receipt of these services may supplant
services for which the adviser or its affiliates might otherwise have paid, it
would tend to reduce their expenses. The adviser and its affiliates exercise
reasonable business judgment in selecting brokers who offer brokerage and
research services to execute securities transactions. They determine in good
faith that commissions charged by such persons are reasonable in relationship to
the value of the brokerage and research services provided. During the fiscal
year(s) ended July 31, 1993, 1992 and 1991, the Trust paid no brokerage
commissions.

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

TRUSTEE LIABILITY

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

INVESTMENT ADVISORY SERVICES
- --------------------------------------------------------------------------------

INVESTMENT ADVISER(S)

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

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

ADVISORY FEES

For its advisory services, Federated Management receives an annual investment
advisory fee as described in the prospectus. For the fiscal years ended July 3l,
l993, l992 and l991, the Fund's adviser earned $4,563,447, $4,375,739 and
$1,740,856, respectively for services provided on behalf of Institutional
Shares, of which $1,647,164, $1,711,388 and $784,040, respectively, were
voluntarily waived because of undertakings to limit the Fund's expenses.

    STATE EXPENSE LIMITATIONS

      The adviser has undertaken to comply with the expense limitations
      established by certain states for investment companies whose shares are
      registered for sale in those states. If the Fund's normal operating
      expenses (including the investment advisory fee, but not including
      brokerage commissions, interest, taxes,

- --------------------------------------------------------------------------------
      and extraordinary expenses) exceed 2 1/2% per year of the first $30
      million of average net assets, 2% per year of the next $70 million of
      average net assets, and 1 1/2% per year of the remaining average net
      assets, the adviser will reimburse the Fund for its expenses over the
      limitation.

      If the Fund's monthly projected operating expenses exceed this limitation,
      the investment advisory fee paid will be reduced by the amount of the
      excess, subject to an annual adjustment. If the expense limitation is
      exceeded, the amount to be reimbursed by the adviser will be limited, in
      any single fiscal year, by the amount of the investment advisory fees.

      This arrangement is not part of the advisory contract and may be amended
      or rescinded in the future.

FUND ADMINISTRATION
- --------------------------------------------------------------------------------

Federated Administrative Services, a subsidiary of Federated Investors, provides
administrative personnel and services to the Trust for a fee as described in the
prospectus for each class of shares of the Fund. For the fiscal years ended July
31, 1993, 1992, and 1991, Federated Administrative Services, Inc., the Trust's
former administrator, earned $770,936, $660,557 and $445,387, respectively. John
A. Staley, IV, an officer of the Trust and Dr. Henry J. Gailliot, an officer of
Federated Management, the adviser to the Fund, each hold approximately l5% and
20%, respectively, of the outstanding common stock of Commercial Data Services,
Inc., a company which provides computer processing services to Federated
Administrative Services, Inc., and Federated Administrative Services. For the
fiscal years ended December 31, 1993, 1992, and 1991, Federated Administrative
Services, Inc. paid approximately $161,547, $201,799 and $170,529, respectively
for services provided by Commercial Data Services, Inc., to the Funds.

SHAREHOLDER SERVICES PLAN
- --------------------------------------------------------------------------------

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

DISTRIBUTION PLAN
- --------------------------------------------------------------------------------

With respect to Institutional Service Shares the Fund has adopted a Plan
pursuant to Rule 12b-1 which was promulgated by the Securities and Exchange
Commission pursuant to the Investment Company Act of 1940. The Plan permits the
payment of fees to brokers for distribution and administrative services and to
administrators for administrative services. The Plan is designed to (i)
stimulate brokers to provide distribution and administrative support services to
shareholders and (ii) stimulate administrators to render administrative support
services to shareholders. The administrative services are provided by a
representative who has knowledge of the shareholder's particular circumstances
and goals. By adopting the Plan, the Board of Trustees expects that the Fund
will be able to achieve a more predictable flow of cash for investment purposes
and to meet redemptions. This will facilitate more efficient portfolio
management and assist the Fund in seeking to achieve its investment objectives.
By identifying potential investors whose needs are served by the Fund's
objectives, and properly servicing these accounts, it may be possible to curb
sharp fluctuations in rates of redemptions and sales. Other benefits may
include: (1) an efficient and effective administrative system; (2) a more
efficient use of shareholder assets by having them rapidly invested with a
minimum of delay and administrative detail; and (3) an efficient and reliable
shareholder records system and prompt responses to shareholder requests and
inquiries concerning their accounts.

CUSTODIAN AND PORTFOLIO RECORDKEEPER.  State Street Bank and Trust Company,
Boston, Massachusetts is custodian for the securities and cash of the Fund.
Federated Services Company, Pittsburgh, Pennsylvania provides certain accounting
and recordkeeping services with respect to the Fund's portfolio investments.

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

DETERMINING NET ASSET VALUE
- --------------------------------------------------------------------------------

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

The Fund's use of the amortized cost method of valuing portfolio instruments
depends on its compliance with certain conditions in Rule 2a-7 (the "Rule")
promulgated by the Securities and Exchange Commission under the Investment
Company Act of 1940. Under the Rule, the Trustees must establish procedures
reasonably designed to stabilize the net asset value per share, as computed for
purposes of distribution and redemption, at $1.00 per share, taking into account
current market conditions and the Fund's investment objective. The procedures
include monitoring the relationship between the amortized cost value per share
and the net asset value per share based upon available indications of market
value. The Trustees will decide what, if any, steps should be taken if there is
a difference of more than 0.5 of 1% between the two values. The Trustees will
take any steps they consider appropriate (such as redemption in kind or
shortening the average portfolio maturity) to minimize any material dilution or
other unfair results arising from differences between the two methods of
determining net asset value.

REDEMPTION IN KIND
- --------------------------------------------------------------------------------

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

THE FUND'S TAX STATUS
- --------------------------------------------------------------------------------

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

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

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

YIELD

The Fund calculates its yield based upon the seven days ending on the day of the
calculation, called the "base period." This yield is computed by:

    - determining the net change in the value of a hypothetical account with a
      balance of one share at the beginning of the base period, with the net
      change excluding capital changes but including the value of

- --------------------------------------------------------------------------------
      any additional shares purchased with dividends earned from the original
      one share and all dividends declared on the original and any purchased
      shares;

    - dividing the net change in the account's value by the value of the account
      at the beginning of the base period to determine the base period return;
      and

    - multiplying the base period return by (365/7).

EFFECTIVE YIELD

The Fund calculates its effective yield by compounding the unannualized base
period return by:

    - adding 1 to the base period return;

    - raising the sum to the 365/7th power; and

    - subtracting 1 from the result.

TOTAL RETURN

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

TREASURY OBLIGATIONS FUND
NOTES TO FINANCIAL STATEMENTS
JULY 31, 1993
- --------------------------------------------------------------------------------

(1) ORGANIZATION

Treasury Obligations Fund (the "Fund") is a diversified portfolio and one of the
portfolios of Money Market Obligations Trust (the "Trust"), a no-load, open-end,
management investment company, which is registered under the Investment Company
Act of 1940, as amended. 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.

(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.

A.  INVESTMENT VALUATION--The Board of Trustees ("Trustees") has determined that
    the best method currently available for valuing portfolio securities is
    amortized cost. The Fund's use of the amortized cost method to value its
    portfolio securities is conditioned on its compliance with Rule 2a-7 under
    the Investment Company Act of 1940, as amended.

B. 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 in support of repurchase agreement
   investments. Additionally, procedures have been established by the Fund to
   monitor, on a daily basis, the market value of each repurchase agreement's
   underlying securities to ensure the existence of a proper level of
   collateral.

   The Fund will only enter into repurchase agreements with banks and other
   recognized financial institutions such as broker/dealers which are deemed by
   the Fund's adviser to be creditworthy pursuant to guidelines established by
   the Trustees. 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.

C.  INCOME--Interest income is recorded on the accrual basis. Interest income
    includes interest and discount earned (net of premium), including original
    issue discount as required by the Internal Revenue Code, plus realized net
    gains, if any, on portfolio securities.

D.  FEDERAL TAXES--It is the Fund's policy to comply with the provisions of the
    Internal Revenue Code applicable to investment companies and to distribute
    to shareholders each year all of its taxable income. Accordingly, no
    provision for federal tax is necessary.

E.  WHEN-ISSUED AND DELAYED DELIVERY TRANSACTIONS--The Fund may engage in
    when-issued or delayed delivery transactions. To the extent the Fund engages
    in such transactions, it will do so for the purpose of acquiring portfolio
    securities consistent with its investment objectives and policies and not
    for the purpose of investment leverage. The Fund will record a when-issued
    security and the related liability on the trade date. Until the securities
    are received and paid for, the Fund will maintain 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.

F.  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 the shares, have been deferred and are being
    amortized using the straight-line method through December, 1994.

G.  OTHER--Investment transactions are accounted for on the date of the
    transaction.

(3) DIVIDENDS

The Fund computes its net income daily and, immediately prior to the calculation
of its net asset value at the close of business, declares and records dividends
to shareholders of record at the time of the previous computation of the Fund's
net asset value. Payment of dividends is made monthly in cash, or in additional
shares at the net asset value on the payable date.

(5) INVESTMENT ADVISORY FEE AND OTHER TRANSACTIONS WITH AFFILIATES

Federated Management, the Fund's investment adviser ("Adviser"), receives for
its services an annual investment advisory fee equal to 0.20 of 1% of the Fund's
average daily net assets. For the fiscal year ended July 31, 1993, Adviser
voluntarily agreed to waive the amount, limited to the amount of the advisory
fee, by which the Fund's aggregate annual operating expenses (including its
investment advisory fee but excluding interest, taxes, brokerage commissions,
insurance premiums, and extraordinary expenses) exceed 0.20 of 1% of its average
daily net assets. This does not include reimbursement to the Fund of any
expenses incurred by shareholders who use the transfer agent's subaccounting
facilities. Adviser can terminate this voluntary agreement at any time at its
sole discretion. For the fiscal year ended July 31, 1993, Adviser earned an
investment advisory fee of $4,563,447 of which $1,647,164 was voluntarily waived
in accordance with such agreement.

Administrative personnel and services were provided at approximate cost by
Federated Administrative Services, Inc. Certain Officers and Trustees of the
Trust are Officers and Directors of the above corporations.

Federated Services Company, the Funds recordkeeper, received for its services a
fee of $267,644 for the year ended July 31, 1993.

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, 1993, and 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 (see page 2 of the prospectus)
for each of the three years in the period then ended, and for the period from
February 23, 1990 (date of initial public investment) to July 31, 1990. 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, 1993, 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
Treasury Obligations Fund (an investment portfolio of Money Market Obligations
Trust) as of July 31, 1993, 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 each of the three years in the
period then ended and for the period from February 23, 1990 (date of initial
public investment) to July 31, 1990, in conformity with generally accepted
accounting principles.
