  Total Institutional Service Shares Operating Expenses (3)     0.45%

(1) The estimated management fee has been reduced to  reflect  the  anticipated 
    voluntary waiver of a portion of the management fee. The  adviser can 
    terminate this voluntary waiver at any time at its sole discretion. The 
    maximum management fee is 0.20%.
(2) The Institutional Service Shares have no present intention of paying or 
    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  0.56% absent the anticipated voluntary waiver of a portion of the 
    management fee.

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

EXAMPLE                                                    1 year  3 years 
You would pay the following expenses on a $1,000 
investment assuming (1) 5% annual return and (2) 
redemption at the end of each time period. 
                                                            $5       $14

   The above example should not be considered a representation of past or 
future expenses. Actual expenses may be greater or  less than those shown. 
This example  is 
based on estimated data for the Fund's fiscal year ending July 31, 1994.
  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  only in short-term 
U.S. government  securities. A  minimum  initial investment  of  $25,000 is  
required. 
Eligibility for  investment in  the Trust  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:

   Maximum Administrative           Average Aggregate Daily Net Assets
           Fee                               of the Fund                      
        .15 of 1%                   on the first $250 million
        .125 of 1%                  on the next $250 million
        .10 of 1%                   on the next $250 million
        .075 of 1%                  on assets in excess of $750 million

The administrative fee received  during any fiscal  year shall be  at least 
$125,000 per portfolio  and $30,000  per each  additional class  of shares.  
Federated Administrative Services may choose voluntarily to waive a portion 
of its fee.
Custodian.  State Street  Bank and Trust Company,  Boston, Massachusetts is  
custodian for the securities and cash of the Fund.
Transfer Agent and Dividend Disbursing Agent.   Federated Services Company, 
Boston, Massachusetts is  transfer agent  for the  shares of,  and dividend  
disbursing agent for the Fund. 
Legal Counsel.  Legal counsel is provided by Houston, Houston and Donnelly, 
Pittsburgh, Pennsylvania and Dickstein, Shapiro and Morin, Washington, D.C. 
Independent Public Accountants. The independent  public accountants for the 
Fund are Arthur Andersen & Co., Pittsburgh, Pennsylvania.
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.  
(Eastern 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., (Eastern time) to  place an order.  The order is  considered received 
immediately. Payment by  federal funds must  be received  before 3:00 p.m.,  
(Eastern time) that day.  Federal funds should  be wired as  follows: 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 
Trust 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.  (Eastern 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 (Eastern  time), the proceeds will  be wired the 
same day to the shareholder's account at a domestic commercial bank which is 
a member of the Federal Reserve System,  and those shares redeemed will not 
be entitled to that day's dividend. A daily dividend will be paid on shares 
redeemed if the  redemption request is  received after  12:00 noon (Eastern  
time). However, the proceeds are not wired until the following business day. 
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., Eastern 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.
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. 
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.

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  more than 10% of  the value of its  net assets in 
illiquid  securities,   including  repurchase   agreements   providing  for   
settlement more than seven days after notice.
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 instruments issued 
by a U.S.  branch of a  domestic bank or  savings and  loan having capital,  
surplus, and undivided  profits in  excess of  $100,000,000 at the  time of  
investment 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 3l, l993, l992  and l991, 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  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 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:

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

 (2) The Institutional Service Shares have no present intention of paying
     or 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 0.54% absent the  anticipated voluntary waiver of a 
     portion  of the management fee.

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

EXAMPLE                                                    1 year  3 years 
You would pay the following expenses on a $1,000 
investment assuming (1) 5% annual return and 
(2) redemption at the end of each time period.                $5      $14

    The above example should not  be considered a representation of past or 
future expenses. Actual expenses may be greater or  less than those shown. 
This example is based on estimated data for the Fund's fiscal year ending 
July 31, 1994.
    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 Trust  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.
In addition, the  Fund may  invest 25% or  more of  the value of  its total  
assets in instruments issued by a U.S. branch of a domestic bank or savings 
and loan  having  capital,  surplus, and  undivided  profits  in  excess of  
$100,000,000 at the time of investment. 
Investment Risks
ECDs, ETDs, Yankee CDs, 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:

   Maximum Administrative           Average Aggregate Daily Net Assets
           Fee                             of the Fund                      
        .15 of 1%                on the first $250 million
        .125 of 1%               on the next $250 million
        .10 of 1%                on the next $250 million
        .075 of 1%               on assets in excess of $750 million

The administrative fee received  during any fiscal  year shall be  at least 
$125,000 per portfolio  and $30,000  per each  additional class  of shares.  
Federated Administrative Services may choose voluntarily to waive a portion 
of its fee.
Custodian.  State Street  Bank and Trust Company,  Boston, Massachusetts is  
custodian for the securities and cash of the Fund.
Transfer Agent and Dividend Disbursing Agent.   Federated Services Company, 
Boston, Massachusetts is  transfer agent  for the  shares of,  and dividend  
disbursing agent for the Fund. 
Legal Counsel.  Legal counsel is provided by Houston, Houston and Donnelly, 
Pittsburgh, Pennsylvania and Dickstein, Shapiro and Morin, Washington, D.C. 
Independent Public Accountants. The independent  public accountants for the 
Fund are Arthur Andersen & Co., Pittsburgh, Pennsylvania.
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.  
(Eastern 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., (Eastern time) to  place an order.  The order is  considered received 
immediately. Payment by  federal funds must  be received  before 3:00 p.m.,  
(Eastern time) that day.  Federal funds should  be wired as  follows: 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 
Trust 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.  (Eastern 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 (Eastern  time), the proceeds will  be wired the 
same day to the shareholder's account at a domestic commercial bank which is 
a member of the Federal Reserve System,  and those shares redeemed will not 
be entitled to that day's dividend. A daily dividend will be paid on shares 
redeemed if the  redemption request is  received after  12:00 noon (Eastern  
time). However, the proceeds are not wired until the following business day. 
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., Eastern 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.
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. 
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.

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 re purchase 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 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 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 instruments issued 
by a U.S.  branch of a  domestic bank or  savings and  loan having capital,  
surplus, and undivided  profits in  excess of  $100,000,000 at the  time of  
investment 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 not 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 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 3l, l993, l992  and l991, 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  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. 
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:

Appendix
STANDARD AND POOR'S CORPORATION CORPORATE BOND RATING DEFINITIONS
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., CORPORATE BOND RATING DEFINITIONS
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.
STANDARD & POOR'S CORPORATION COMMERCIAL PAPER RATING DEFINITIONS
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. COMMERCIAL PAPER RATING DEFINITIONS
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.
FITCH INVESTORS SERVICE, INC. SHORT-TERM DEBT RATING DEFINITIONS 
F-1+ _ Exceptionally Strong Credit Quality. Issues assigned this rating are 
regarded as having the strongest degree of assurance for timely payment.
F-1 _ Very Strong  Credit Quality. Issues  assigned this rating  reflect an 
assurance for timely payment only slightly less in degree than issues rated 
"F-1+."
F-2 _ Good Credit Quality. Issues carrying  this rating have a satisfactory 
degree of assurance for timely payment, but the  margin of safety is not as 
great as the "F-1+" and "F-1" categories.

(1) The  estimated  management fee  has  been  reduced to  reflect  the

    adviser can terminate this voluntary waiver at any time at its  sole 
    discretion. The maximum management fee is 0.20%.

(2) The Institutional Service Shares have no present intention of paying or 
    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  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 purpose  of this table  is to  assist an investor  in understanding the  
various costs  and expenses  that  a shareholder  of Institutional  Service  
Shares of  the Fund  will bear,  either  directly or  indirectly. For  more  
complete descriptions of the various costs and  expenses, see "Investing in 
the Fund" and "Trust Information." Wire-transferred redemptions of less than 
$5,000 may be subject to additional fees.

EXAMPLE                                                   1 year  3 years 
You would pay the following expenses on a $1,000 
investment assuming (1) 5% annual return and (2) 
redemption at the end of each time period.                 $5      $14

 The above  example should  not be  considered a  representation of  past or  
future expenses. Actual expenses may be greater or  less than those shown. 
This example is based on estimated data for the Fund's fiscal year ending 
July 31, 1994.

 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 Trust  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. Municipal leases  are obligations issued  by state and 
   local governments or authorities to finance the acquisition of equipment 
   and facilities.  They  may take  the  form of  a  lease, an  installment  
   purchase contract,  a  conditional sales  contract,  or  a participation  
   interest in any of the above.
Ratings.  The  securities in which  the Fund invests  must be  rated in the  
highest short-term  rating category  by one  or more  nationally recognized  
statistical rating organizations ("NRSROs") or be  of comparable quality to 
securities having  such  ratings. An  NRSRO's  highest  rating category  is  
determined without regard  for sub-categories and  gradations. For example,  
securities rated SP-1+  or SP-1 by  Standard &  Poor's 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.
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:

 Maximum Administrative           Average Aggregate Daily Net Assets
           Fee                        of the Fund                      
        .15 of 1%                on the first $250 million
        .125 of 1%               on the next $250 million
        .10 of 1%                on the next $250 million
        .075 of 1%               on assets in excess of $750 million

The administrative fee received  during any fiscal  year shall be  at least 
$125,000 per portfolio  and $30,000  per each  additional class  of shares.  
Federated Administrative Services may choose voluntarily to waive a portion 
of its fee.
Custodian.  State Street  Bank and Trust Company,  Boston, Massachusetts is  
custodian for the securities and cash of the Fund.
Transfer Agent and Dividend Disbursing Agent.   Federated Services Company, 
Boston, Massachusetts is  transfer agent  for the  shares of,  and dividend  
disbursing agent for the Fund. 
Legal Counsel.  Legal counsel is provided by Houston, Houston and Donnelly, 
Pittsburgh, Pennsylvania and Dickstein, Shapiro and Morin, Washington, D.C. 
Independent Public Accountants. The independent  public accountants for the 
Fund are Arthur Andersen & Co., Pittsburgh, Pennsylvania.
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.  
(Eastern 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., (Eastern time) to  place an order.  The order is  considered received 
immediately. Payment by  federal funds must  be received  before 3:00 p.m.,  
(Eastern time) that day.  Federal funds should  be wired as  follows: 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 Fund_Institutional Service Shares to: Tax-Free 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 
Trust 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.  (Eastern 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 (Eastern  time), the proceeds will  be wired the 
same day to the shareholder's account at a domestic commercial bank which is 
a member of the Federal Reserve System,  and those shares redeemed will not 
be entitled to that day's dividend. A daily dividend will be paid on shares 
redeemed if the  redemption request is  received after  12:00 noon (Eastern  
time). However, the proceeds are not wired until the following business day. 
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 
25.4% of the voting securities of the  Fund, and First Union National Bank, 
Charlotte, North Carolina owned 25.2% 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.
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. 
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.

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
The Fund may  purchase municipal  securities in  the form  of participation  
interests that  represent  an  undivided  proportional  interest  in  lease  
payments by a governmental or nonprofit entity. The lease payments and other 
rights under the lease provide for and secure payments on the certificates. 
Lease obligations may be limited by municipal  charter or the nature of the 
appropriation for  the lease.  Furthermore, a  lease  may provide  that the  
participants  cannot  accelerate   lease  obligations  upon   default.  The   
participants would only be  able to enforce  lease payments as  they became 
due. In the  event of  a default  or failure  of appropriation,  unless the  
participation interests  are  credit  enhanced,  it  is  unlikely that  the  
participants would be  able to  obtain an  acceptable substitute  source of  
payment.
In determining the liquidity of municipal  lease securities, the investment 
adviser, under the authority delegated by the  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. 
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 case 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 instruments issued 
by a U.S.  branch of a  domestic bank or  savings and  loan having capital,  
surplus, and undivided  profits in  excess of  $100,000,000 at the  time of  
investment 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 issued  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 not 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 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 3l,  l993, l992  and l991,  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  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.
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  ___%  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.
[Insert table]
Note: The maximum marginal tax rate for each bracket was used in calculating 
the taxable yield equivalent. The chart  above is for illustrative purposes  
only. It is not an indicator of past or future performance of the Fund.
*Some portion of the Fund's income may be subject to the federal alternative 
minimum tax and state and local taxes.
Total Return
Average annual total return is the average  compounded rate of return for a 
given period that would  equate a $1,000  initial investment to  the ending 
redeemable value  of  that  investment.  The  ending  redeemable  value  is  
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:

Appendix
STANDARD AND POOR'S CORPORATION CORPORATE BOND RATING DEFINITIONS
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., CORPORATE BOND RATING DEFINITIONS
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.
STANDARD & POOR'S CORPORATION COMMERCIAL PAPER RATING DEFINITIONS
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. COMMERCIAL PAPER RATING DEFINITIONS
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.
FITCH INVESTORS SERVICE, INC. SHORT-TERM DEBT RATING DEFINITIONS 
F-1+ _ Exceptionally Strong Credit Quality. Issues assigned this rating are 
regarded as having the strongest degree of assurance for timely payment.
F-1 _ Very Strong  Credit Quality. Issues  assigned this rating  reflect an 
assurance for timely payment only slightly less in degree than issues rated 
"F-1+."
F-2 _ Good Credit Quality. Issues carrying  this rating have a satisfactory 
degree of assurance for timely payment, but the  margin of safety is not as 
great as the "F-1+" and "F-1" categories.

  less than the average amount shown.
  The purpose of this table is  to assist an investor in  understanding the 
various costs  and expenses  that  a shareholder  of  Institutional Service  
Shares of  the Fund  will  bear, either  directly or  indirectly.  For more  
complete descriptions of the various costs  and expenses, see "Investing in

  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

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 Trust  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:

  Maximum Administrative           Average Aggregate Daily Net Assets
           Fee                           of the Fund                      
        .15 of 1%                   on the first $250 million
        .125 of 1%                  on the next $250 million
        .10 of 1%                   on the next $250 million
        .075 of 1%                  on assets in excess of $750 million
The administrative fee received  during any fiscal  year shall be  at least 
$125,000 per portfolio  and $30,000  per each  additional class  of shares.  
Federated Administrative Services may choose voluntarily to waive a portion 
of its fee.
Custodian.  State Street  Bank and Trust Company,  Boston, Massachusetts is  
custodian for the securities and cash of the Fund.
Transfer Agent and Dividend Disbursing Agent.   Federated Services Company, 
Boston, Massachusetts is  transfer agent  for the  shares of,  and dividend  
disbursing agent for the Fund. 
Legal Counsel.  Legal counsel is provided by Houston, Houston and Donnelly, 
Pittsburgh, Pennsylvania and Dickstein, Shapiro and Morin, Washington, D.C. 
Independent Public Accountants. The independent  public accountants for the 
Fund are Arthur Andersen & Co., Pittsburgh, Pennsylvania.
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.  
(Eastern 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., (Eastern time) to  place an order.  The order is  considered received 
immediately. Payment by  federal funds must  be received  before 3:00 p.m.,  
(Eastern time) that day.  Federal funds should  be wired as  follows: 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 
Trust 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.  (Eastern 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 (Eastern  time), the proceeds will  be wired the 
same day to the shareholder's account at a domestic commercial bank which is 
a member of the Federal Reserve System,  and those shares redeemed will not 
be entitled to that day's dividend. A daily dividend will be paid on shares 
redeemed if the  redemption request is  received after  12:00 noon (Eastern  
time). However, the proceeds are not wired until the following business day. 
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., Eastern 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.
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. 
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.

* 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.

   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 ratio of expenses and net  investment income would have been 
   0.27% and 3.04%, 0.28% and 4.41%, 0.29% and  6.56%, and 0.35% and 8.01%,

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  more than 15% of  the value of its  net assets in 
illiquid  securities,   including  repurchase   agreements   providing  for   
settlement more than seven days after notice.
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 instruments issued 
by a U.S.  branch of a  domestic bank or  savings and  loan having capital,  
surplus, and undivided  profits in  excess of  $100,000,000 at the  time of  
investment 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 issued  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 not 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. 
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:

                      MONEY MARKET OBLIGATIONS TRUST
  
                          DISTRIBUTOR'S CONTRACT
  
        AGREEMENT made this 1st day of March, 1994, by and between MONEY 
  MARKET OBLIGATIONS TRUST (the "Trust"), a Massachusetts business trust, 
  and FEDERATED SECURITIES CORP. ("FSC"), a Pennsylvania corporation.
  
        In consideration of the mutual covenants hereinafter contained, it 
  is hereby agreed by and between the parties hereto as follows:
  
        1.    The Trust hereby appoints FSC as its agent to sell and 
  distribute shares of the Trust which may be offered in one or more 
  series (the "Funds") consisting of one or more classes (the "Classes") 
  of shares (the "Shares"), as described and set forth on one or more 
  exhibits to this Agreement, at the current offering price thereof as 
  described and set forth in the current Prospectuses of the Trust.  FSC 
  hereby accepts such appointment and agrees to provide such other 
  services for the Trust, if any, and accept such compensation from the 
  Trust, if any, as set forth in the applicable exhibit to this Agreement.
  
        2.    The sale of any Shares may be suspended without prior notice 
  whenever in the judgment of the Trust it is in its best interest to do 
  so.  
  
        3.    Neither FSC nor any other person is authorized by the Trust 
  to give any information or to make any representation relative to any 
  Shares other than those contained in the Registration Statement, 
  Prospectuses, or Statements of Additional Information ("SAIs") filed 
  with the Securities and Exchange Commission, as the same may be amended 
  from time to time, or in any supplemental information to said 
  Prospectuses or SAIs approved by the Trust.  FSC agrees that any other 
  information or representations other than those specified above which it 
  or any dealer or other person who purchases Shares through FSC may make 
  in connection with the offer or sale of Shares, shall be made entirely 
  without liability on the part of the Trust.  No person or dealer, other 
  than FSC, is authorized to act as agent for the Trust for any purpose.  
  FSC agrees that in offering or selling Shares as agent of the Trust, it 
  will, in all respects, duly conform to all applicable state and federal 
  laws and the rules and regulations of the National Association of 
  Securities Dealers, Inc., including its Rules of Fair Practice.  FSC 
  will submit to the Trust copies of all sales literature before using the 
  same and will not use such sales literature if disapproved by the Trust.
  
        4.    This Agreement is effective with respect to each Class as of 
  the date of execution of the applicable exhibit and shall continue in 
  effect with respect to each Class presently set forth on an exhibit and 
  any subsequent Classes added pursuant to an exhibit during the initial 
  term of this Agreement for one year from the date set forth above, and 
  thereafter for successive periods of one year if such continuance is 
  approved at least annually by the Trustees of the Trust including a 
  majority of the members of the Board of Trustees of the Trust who are 
  not interested persons of the Trust and have no direct or indirect 
  financial interest in the operation of any Distribution Plan relating to 
  the Trust or in any related documents to such Plan (the "Disinterested 
  Trustees") cast in person at a meeting called for that purpose.  If a 
  Class is added after the first annual approval by the Trustees as 
  described above, this Agreement will be effective as to that Class upon 
  execution of the applicable exhibit and will continue in effect until 
  the next annual approval of this Agreement by the Trustees and 
  thereafter for successive periods of one year, subject to approval as 
  described above.
  
        5.    This Agreement may be terminated with regard to a particular 
  Fund or Class at any time, without the payment of any penalty, by the 
  vote of a majority of the Disinterested Trustees or by a majority of the 
  outstanding voting securities of the particular Fund or Class on not 
  more than sixty (60) days' written notice to any other party to this 
  Agreement.  This Agreement may be terminated with regard to a particular 
  Fund or Class by FSC on sixty (60) days' written notice to the Trust.
  
        6.    This Agreement may not be assigned by FSC and shall 
  automatically terminate in the event of an assignment by FSC as defined 
  in the Investment Company Act of 1940, as amended, provided, however, 
  that FSC may employ such other person, persons, corporation or 
  corporations as it shall determine in order to assist it in carrying out 
  its duties under this Agreement.  
  
        7.    FSC shall not be liable to the Trust 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 
  by this Agreement.  
  
        8.    This Agreement may be amended at any time by mutual 
  agreement in writing of all the parties hereto, provided that such 
  amendment is approved by the Trustees of the Trust including a majority 
  of the Disinterested Trustees of the Trust cast in person at a meeting 
  called for that purpose.  
  
        9.    This Agreement shall be construed in accordance with and 
  governed by the laws of the Commonwealth of Pennsylvania.  
  
        10.   (a)   Subject to the conditions set forth below, the Trust 
  agrees to indemnify and hold harmless FSC and each person, if any, who 
  controls FSC within the meaning of Section 15 of the Securities Act of 
  1933 and Section 20 of the Securities Act of 1934, as amended, against 
  any and all loss, liability, claim, damage and expense whatsoever 
  (including but not limited to any and all expenses whatsoever reasonably 
  incurred in investigating, preparing or defending against any 
  litigation, commenced or threatened, or any claim whatsoever) arising 
  out of or based upon any untrue statement or alleged untrue statement of 
  a material fact contained in the Registration Statement, any 
  Prospectuses or SAIs (as from time to time amended and supplemented) or 
  the omission or alleged omission therefrom of a material fact required 
  to be stated therein or necessary to make the statements therein not 
  misleading, unless such statement or omission was made in reliance upon 
  and in conformity with written information furnished to the Trust about 
  FSC by or on behalf of FSC expressly for use in the Registration 
  Statement, any Prospectuses and SAIs or any amendment or supplement 
  thereof.  
  
                    If any action is brought against FSC or any 
  controlling person thereof with respect to which indemnity may be sought 
  against the Trust pursuant to the foregoing paragraph, FSC shall 
  promptly notify the Trust in writing of the institution of such action 
  and the Trust shall assume the defense of such action, including the 
  employment of counsel selected by the Trust and payment of expenses.  
  FSC or any such controlling person thereof shall have the right to 
  employ separate counsel in any such case, but the fees and expenses of 
  such counsel shall be at the expense of FSC or such controlling person 
  unless the employment of such counsel shall have been authorized in 
  writing by the Trust in connection with the defense of such action or 
  the Trust shall not have employed counsel to have charge of the defense 
  of such action, in any of which events such fees and expenses shall be 
  borne by the Trust.  Anything in this paragraph to the contrary 
  notwithstanding, the Trust shall not be liable for any settlement of any 
  such claim of action effected without its written consent.  The Trust 
  agrees promptly to notify FSC of the commencement of any litigation or 
  proceedings against the Trust or any of its officers or Trustees or 
  controlling persons in connection with the issue and sale of Shares or 
  in connection with the Registration Statement, Prospectuses, or SAIs.  
  
              (b)   FSC agrees to indemnify and hold harmless the Trust, 
  each of its Trustees, each of its officers who have signed the 
  Registration Statement and each other person, if any, who controls the 
  Trust within the meaning of Section 15 of the Securities Act of 1933, 
  but only with respect to statements or omissions, if any, made in the 
  Registration Statement or any Prospectus, SAI, or any amendment or 
  supplement thereof in reliance upon, and in conformity with, information 
  furnished to the Trust about FSC by or on behalf of FSC expressly for 
  use in the Registration Statement or any Prospectus, SAI, or any 
  amendment or supplement thereof.  In case any action shall be brought 
  against the Trust or any other person so indemnified based on the 
  Registration Statement or any Prospectus, SAI, or any amendment or 
  supplement thereof, and with respect to which indemnity may be sought 
  against FSC, FSC shall have the rights and duties given to the Trust, 
  and the Trust and each other person so indemnified shall have the rights 
  and duties given to FSC by the provisions of subsection (a) above.  
  
                    (c)   Nothing herein contained shall be deemed to 
  protect any person against liability to the Trust or its shareholders to 
  which such person would otherwise be subject by reason of willful 
  misfeasance, bad faith or gross negligence in the performance of the 
  duties of such person or by reason of the reckless disregard by such 
  person of the obligations and duties of such person under this 
  Agreement.  
  
                    (d)   Insofar as indemnification for liabilities may 
  be permitted pursuant to Section 17 of the Investment Company Act of 
  1940, as amended, for Trustees, officers, FSC and controlling persons of 
  the Trust by the Trust pursuant to this Agreement, the Trust is aware of 
  the position of the Securities and Exchange Commission as set forth in 
  the Investment Company Act Release No. IC-11330.  Therefore, the Trust 
  undertakes that in addition to complying with the applicable provisions 
  of this Agreement, in the absence of a final decision on the merits by a 
  court or other body before which the proceeding was brought, that an 
  indemnification payment will not be made unless in the absence of such a 
  decision, a reasonable determination based upon factual review has been 
  made (i) by a majority vote of a quorum of non-party Disinterested 
  Trustees, or (ii) by independent legal counsel in a written opinion that 
  the indemnitee was not liable for an act of willful misfeasance, bad 
  faith, gross negligence or reckless disregard of duties.  The Trust 
  further undertakes that advancement of expenses incurred in the defense 
  of a proceeding (upon undertaking for repayment unless it is ultimately 
  determined that indemnification is appropriate) against an officer, 
  Trustee, FSC or controlling person of the Trust will not be made absent 
  the fulfillment of at least one of the following conditions: (i) the 
  indemnitee provides security for his undertaking; (ii) the Trust is 
  insured against losses arising by reason of any lawful advances; or 
  (iii) a majority of a quorum of non-party Disinterested Trustees or 
  independent legal counsel in a written opinion makes a factual 
  determination that there is reason to believe the indemnitee will be 
  entitled to indemnification.  
  
        11.   FSC is hereby expressly put on notice of the limitation of 
  liability as set forth in Article XI of the Declaration of Trust and 
  agrees that the obligations assumed by the Trust pursuant to this 
  Agreement shall be limited in any case to the Trust and its assets and 
  FSC shall not seek satisfaction of any such obligation from the 
  shareholders of the Trust, the Trustees, officers, employees or agents 
  of the Trust, or any of them.
  
        12.   If at any time the Shares of any Fund are offered in two or 
  more Classes, FSC agrees to adopt compliance standards as to when a 
  class of shares may be sold to particular investors.
  
        13.   This Agreement will become binding on the parties hereto 
  upon the execution of the attached exhibits to the Agreement.

  Money Market Obligations Trust and Federated Securities Corp. with 
  respect to Classes of the Funds set forth above.
  
        1.    The Trust hereby appoints FSC to engage in activities 
  principally intended to result in the sale of shares of the above-listed 
  Classes (the "Shares").  Pursuant to this appointment, FSC is authorized 
  to select a group of brokers (the "Brokers") to sell Shares at the 
  current offering price thereof as described and set forth in the 
  respective prospectuses of the Trust, and to render administrative 
  support services to the Trust and its shareholders.  In addition, FSC is 
  authorized to select a group of administrators ("Administrators") to 
  render administrative support services to the Trust and its 
  shareholders.
  
        2.    Administrative support services may include, but are not 
  limited to, the following functions:  1) account openings:  the Broker 
  or Administrator communicates account openings via computer terminals 
  located on the Broker's or Administrator's premises; 2) account

  transactions are entered through the Broker's or Administrator's own 
  personal computer or through the use of a toll-free telephone number; 4) 
  enter redemption transactions:  Broker or Administrator enters 
  redemption transactions in the same manner as purchases; 5) account 
  maintenance:  Broker or Administrator provides or arranges to provide 
  accounting support for all transactions.  Broker or Administrator also 
  wires funds and receives funds for Trust share purchases and 
  redemptions, confirms and reconciles all transactions, reviews the 
  activity in the Trust's accounts, and provides training and supervision 
  of its personnel; 6) interest posting:  Broker or Administrator posts 
  and reinvests dividends to the Trust's accounts; 7) prospectus and

        3.    During the term of this Agreement, the Trust will pay FSC 
  for services pursuant to this Agreement, a monthly fee computed at the 
  annual rate of up to 0.25% of the average aggregate net asset value of 
  the Institutional Service Shares of the Government Obligations Fund, 
  Prime Obligations Fund, Tax-Free Obligations Fund, and Treasury 
  Obligations Fund held during the month.  For the month in which this 
  Agreement becomes effective or terminates, there shall be an appropriate 
  proration of any fee payable on the basis of the number of days that the 
  Agreement is in effect during the month.
  
        4.    FSC may from time-to-time and for such periods as it deems 
  appropriate reduce its compensation to the extent any Classes' expenses 
  exceed such lower expense limitation as FSC may, by notice to the Trust, 
  voluntarily declare to be effective.
  
         5.   FSC will enter into separate written agreements with various 
  firms to provide certain of the services set forth in Paragraph 1 
  herein.  FSC, in its sole discretion, may pay Brokers and Administrators 
  a periodic fee in respect of Shares owned from time to time by their 
  clients or customers.  The schedules of such fees and the basis upon 
  which such fees will be paid shall be determined from time to time by 
  FSC in its sole discretion.
  
        6.    FSC will prepare reports to the Board of Trustee of the 
  Trust on a quarterly basis showing amounts expended hereunder including 
  amounts paid to Brokers and Administrators and the purpose for such 
  payments.
