GENERAL INFORMATION
- --------------------------------------------------------------------------------

   
The  Trust was established as a Massachusetts business trust under a Declaration
of Trust dated May 24, 1985. 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 Board of Trustees (the  "Trustees") has established two classes
of  shares,  Institutional  Shares   and  Institutional  Service  Shares.   This
prospectus relates only to Institutional Shares (the "Shares") of the Fund.
    

   
Shares  of  the  Fund  are  sold  primarily  to  accounts  for  which  financial
institutions act in a fiduciary or  agency capacity, and other accounts where  a
financial  institution maintains master accounts with an aggregate investment of
at least $400 million in certain  mutual funds which are advised or  distributed
by  affiliates  of  Federated  Investors.  Shares  are  also  made  available to
financial intermediaries, public, and private organizations. In addition, Shares
are designed  to  provide an  appropriate  investment for  particular  financial
institutions that are subject to government agency regulations, including credit
unions,  savings associations,  and national  banks. An  investment in  the Fund
serves as a  convenient means of  accumulating an interest  in a  professionally
managed,  diversified portfolio which invests  at least 65% of  the value of its
total assets in U.S. government  securities, all of which government  securities
will  be adjustable  and floating rate  mortgage securities which  are issued or
guaranteed as to payment of principal  and interest by the U.S. government,  its
agencies  or instrumentalities. A  minimum initial investment  of $25,000 over a
90-day period is required.
    

   
Shares are currently sold and redeemed at  net asset value without a sales  load
imposed by the Fund.
    

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

INVESTMENT OBJECTIVE

The  investment objective  of the Fund  is to provide  current income consistent
with minimal  volatility  of principal.  Current  income includes,  in  general,
discount  earned  on U.S.  Treasury bills  and  agency discount  notes, interest
earned on mortgage related securities and other U.S. government securities,  and
short-term  capital gains.  The investment  objective cannot  be changed without
approval of shareholders. The Fund  anticipates that it will experience  minimal
volatility  of principal  due to the  frequent adjustments to  interest rates on
adjustable and floating rate mortgage  securities which comprise the  portfolio.
Of  course, there  can be no  assurance that the  Fund will be  able to maintain
minimal  volatility  of  principal  or  that  it  will  achieve  its  investment
objective.  The Fund endeavors to achieve  its investment objective, however, by
following the investment policies described in this prospectus.

INVESTMENT POLICIES

Except as otherwise noted,  the investment policies described  below may not  be
changed by the Trustees without shareholder approval.

                                       3

The  Fund will limit its investments to those that are permitted for purchase by
federal savings  associations  pursuant  to applicable  rules,  regulations,  or
interpretations of the Office of Thrift Supervision and by federal credit unions
under   the  Federal   Credit  Union  Act   and  the   rules,  regulations,  and
interpretations of the National Credit Union Administration (the "NCUA"). Should
additional permitted investments  be allowed as  a result of  future changes  in
applicable  regulations or  federal laws, the  Fund reserves  the right, without
shareholder approval,  to  make  such investments  consistent  with  the  Fund's
investment  objective,  policies,  and  limitations.  Further,  should  existing
statutes or regulations change so as to cause any securities held by the Fund to
become ineligible for purchase by federal savings associations or federal credit
unions, the Fund will dispose of  those securities at times advantageous to  the
Fund.

As  operated within the above limitations, and pursuant to the Fund's investment
policy, which  may  be  changed  without  shareholder  approval,  to  limit  its
investment  to securities that  are appropriate direct  investments for national
banks, the Fund will also serve as an appropriate vehicle for a national bank as
an investment for its own account.

ACCEPTABLE INVESTMENTS.  The Fund pursues its investment objective by  investing
at  least  65% of  the value  of its  total assets  in a  professionally managed
portfolio of U.S. government securities. As a matter of investment policy, which
may be  changed  without shareholder  approval,  all of  these  U.S.  government
securities  will be adjustable  and floating rate  mortgage securities which are
issued or  guaranteed  as to  payment  of principal  and  interest by  the  U.S.
government, its agencies or instrumentalities.

The  types  of mortgage  securities in  which  the Fund  may invest  include the
following:

    - adjustable rate mortgage securities;

    - collateralized mortgage obligations;

    - real estate mortgage investment conduits; and

    - other securities  collateralized  by  or representing  interests  in  real
      estate  mortgages whose interest rates reset at periodic intervals and are
      issued  or   guaranteed  by   the  U.S.   government,  its   agencies   or
      instrumentalities.

In  addition to  the securities  described above,  the Fund  may also  invest in
direct obligations of the U.S. Treasury, such as U.S. Treasury bills, notes, and
bonds, as well as obligations  of U.S. government agencies or  instrumentalities
which are not collateralized by or represent interests in real estate mortgages,
as described above.

   
The  Fund may also invest in mortgage  related securities, as defined in section
3(a)(41) of the Securities Exchange Act of 1934, as amended, which are issued by
private entities such as investment banking  firms and companies related to  the
construction industry. The privately issued mortgage related securities in which
the Fund may invest include:
    

    - privately issued securities which are collateralized by pools of mortgages
      in  which  each mortgage  is  guaranteed as  to  payment of  principal and
      interest by an agency or instrumentality of the U.S. government;

                                       4

    - privately issued securities which are collateralized by pools of mortgages
      in which payment of  principal and interest are  guaranteed by the  issuer
      and such guarantee is collateralized by U.S. government securities; and

    - other  privately issued securities  in which the  proceeds of the issuance
      are invested in mortgage  backed securities and  payment of the  principal
      and  interest are supported by the credit of any agency or instrumentality
      of the U.S. government.

The privately issued mortgage related securities provide for a periodic  payment
consisting  of  both  interest  and principal.  The  interest  portion  of these
payments will be distributed by the Fund as income, and the capital portion will
be reinvested.

   
The prices of fixed  income securities fluctuate inversely  to the direction  of
interest rates.
    

   
ADJUSTABLE  RATE MORTGAGE SECURITIES  ("ARMS").  ARMs  are pass-through mortgage
securities with adjustable rather than fixed  interest rates. The ARMs in  which
the  Fund  invests  are  issued  by  Government  National  Mortgage  Association
("GNMA"), Federal National Mortgage Association ("FNMA"), and Federal Home  Loan
Mortgage Corporation ("FHLMC") and are actively traded. The underlying mortgages
which  collateralize ARMs  issued by  GNMA are  fully guaranteed  by the Federal
Housing Administration ("FHA")  or Veterans Administration  ("VA"), while  those
collateralizing  ARMs  issued  by  FHLMC  or  FNMA  are  typically  conventional
residential mortgages  conforming  to  strict  underwriting  size  and  maturity
constraints.
    

   
Unlike  conventional bonds, ARMs  pay back principal  over the life  of the ARMs
rather than at maturity.  Thus, a holder  of the ARMs, such  as the Fund,  would
receive  monthly scheduled  payments of principal  and interest  and may receive
unscheduled  principal  payments   representing  payments   on  the   underlying
mortgages.  At the time that a holder of the ARMs reinvests the payments and any
unscheduled prepayments of principal that it receives, the holder may receive  a
rate  of interest which is actually lower than  the rate of interest paid on the
existing ARMs. As a consequence, ARMs may be a less effective means of  "locking
in" long-term interest rates than other types of U.S. government securities.
    

   
Not  unlike  other U.S.  government securities,  the market  value of  ARMs will
generally vary inversely with changes in market interest rates. Thus, the market
value of ARMs generally  declines when interest rates  rise and generally  rises
when interest rates decline.
    

   
While  ARMs generally entail  less risk of  a decline during  periods of rapidly
rising rates, ARMs may  also have less potential  for capital appreciation  than
other   similar  investments  (e.g.,  investments  with  comparable  maturities)
because, as interest rates decline, the likelihood increases that mortgages will
be  prepaid.  Furthermore,  if  ARMs  are  purchased  at  a  premium,   mortgage
foreclosures  and unscheduled  principal payments may  result in some  loss of a
holder's principal investment to the extent of the premium paid. Conversely,  if
ARMs  are purchased at a discount, both  a scheduled payment of principal and an
unscheduled prepayment of principal would increase current and total returns and
would accelerate the  recognition of income,  which would be  taxed as  ordinary
income when distributed to shareholders.
    

                                       5

COLLATERALIZED  MORTGAGE  OBLIGATIONS  ("CMOs").    CMOs  are  bonds  issued  by
single-purpose,  stand-alone  finance  subsidiaries   or  trusts  of   financial
institutions,  government agencies, investment bankers,  or companies related to
the construction industry. CMOs purchased by the Fund may be:

    - collateralized by pools of mortgages in which each mortgage is  guaranteed
      as to payment of principal and interest by an agency or instrumentality of
      the U.S. government;

    - collateralized  by pools  of mortgages in  which payment  of principal and
      interest is guaranteed by the issuer and such guarantee is  collateralized
      by U.S. government securities; or

    - securities  in which the proceeds of the issuance are invested in mortgage
      securities and payment of the principal and interest are supported by  the
      credit of an agency or instrumentality of the U.S. government.

The  Fund will  only purchase  CMOs which  are investment  grade, as  rated by a
nationally recognized statistical rating organization.

REAL ESTATE MORTGAGE  INVESTMENT CONDUITS  ("REMICs).  REMICs  are offerings  of
multiple  class real estate  mortgage-backed securities which  qualify and elect
treatment as such  under provisions  of the  Internal Revenue  Code. Issuers  of
REMICs  may  take several  forms,  such as  trusts,  partnerships, corporations,
associations or a segregated pool of mortgages. Once REMIC status is elected and
obtained, the entity is not subject to federal income taxation. Instead,  income
is  passed through  the entity and  is taxed to  the person or  persons who hold
interests in the REMIC. A REMIC interest must consist of one or more classes  of
"regular interests," some of which may offer adjustable rates (the type in which
the  Fund primarily  invests), and  a single  class of  "residual interests." To
qualify as a REMIC,  substantially all of  the assets of the  entity must be  in
assets directly or indirectly secured principally by real property.

REGULATORY  COMPLIANCE.   In accordance  with the  Rules and  Regulations of the
NCUA, unless the purchase is made solely to reduce interest-rate risk, the  Fund
will  not invest in  any CMO or REMIC  security that meets  any of the following
three tests: (1) the CMO or REMIC  has an expected average life greater than  10
years;  (2) the average life of the CMO or REMIC extends by more than four years
assuming an immediate and  sustained parallel shift in  the yield curve of  plus
300  basis points, or shortens by more  than six years assuming an immediate and
sustained parallel shift in the  yield curve of minus  300 basis points; or  (3)
the  estimated change in the price of the CMO  or REMIC is more than 17%, due to
an immediate and sustained parallel  shift in the yield  curve of plus or  minus
300 basis points.

Neither  test (1)  nor (2) above  apply to  floating or adjustable  rate CMOs or
REMICs with all of the following  characteristics: (a) the interest rate of  the
instrument  is  reset at  least annually;  (b)  the interest  rate is  below the
contractual cap of the instrument; (c)  the instrument is tied to a  widely-used
market rate; and (d) the instrument varies directly (not inversely) and is reset
in proportion with the index's changes.

The  Fund may not purchase  a residual interest in a  CMO or REMIC. In addition,
the Fund will not purchase zero  coupon securities with maturities greater  than
10 years.

                                       6

   
RESETS.  The interest rates paid on the ARMs, CMOs, and REMICs in which the Fund
invests generally are readjusted or reset at intervals of one year or less to an
increment  over  some  predetermined interest  rate  index. There  are  two main
categories of indices: those based on U.S. Treasury securities and those derived
from a calculated measure, such as a cost of funds index or a moving average  of
mortgage  rates. Commonly  utilized indices  include the  one-year and five-year
constant maturity Treasury Note rates,  the three-month Treasury Bill rate,  the
180-day  Treasury  Bill  rate,  rates on  longer-term  Treasury  securities, the
National Median Cost  of Funds,  the one-month or  three-month London  Interbank
Offered  Rate (LIBOR), the  prime rate of  a specific bank,  or commercial paper
rates. Some indices, such as the one-year constant maturity Treasury Note  rate,
closely  mirror  changes in  market  interest rate  levels.  Others tend  to lag
changes in market rate levels and tend to be somewhat less volatile.
    

   
CAPS AND FLOORS.  The underlying  mortgages which collateralize the ARMs,  CMOs,
and  REMICs in which the Fund invests will frequently have caps and floors which
limit the maximum amount by which the loan rate to the residential borrower  may
change up or down: (1) per reset or adjustment interval and (2) over the life of
the  loan.  Some residential  mortgage  loans restrict  periodic  adjustments by
limiting changes  in  the borrower's  monthly  principal and  interest  payments
rather  than limiting  interest rate changes.  These payment caps  may result in
negative amortization.
    

The value of mortgage securities  in which the Fund  invests may be affected  if
market interest rates rise or fall faster and farther than the allowable caps or
floors on the underlying residential mortgage loans. An example of the effect of
caps  and floors  on a residential  mortgage loan  may be found  in the Combined
Statement of  Additional Information.  Additionally,  even though  the  interest
rates  on the underlying residential  mortgages are adjustable, amortization and
prepayments may occur, thereby causing the effective maturities of the  mortgage
securities in which the Fund invests to be shorter than the maturities stated in
the underlying mortgages.

TEMPORARY  INVESTMENTS.  For  defensive purposes only, the  Fund may also invest
temporarily in cash and money market instruments during times of unusual  market
conditions  and  to maintain  liquidity.  Money market  instruments  may include
obligations such as:

    - obligations of the U.S. government  or its agencies or  instrumentalities;
      and

    - repurchase agreements.

REPURCHASE  AGREEMENTS.  Repurchase agreements  are arrangements in which banks,
broker/dealers, and other recognized financial institutions sell U.S. government
securities or other  securities to the  Fund and agree  at the time  of sale  to
repurchase  them at a mutually  agreed upon time and  price within one year from
the date  of  acquisition. To  the  extent that  the  original seller  does  not
repurchase  the securities from the  Fund, the Fund could  receive less than the
repurchase price on any sale of such securities.

LENDING OF PORTFOLIO SECURITIES.   In order to  generate additional income,  the
Fund  may lend portfolio securities  on a short-term or  a long-term basis 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
investment  adviser has determined are creditworthy under guidelines established
by the Fund's Board of Trustees and will

                                       7

receive collateral in the form of cash or U.S. government securities equal to at
least 100% of the value of the securities loaned.

   
There is the risk that when lending portfolio securities, the securities may not
be available to the Fund on a timely basis and the Fund may, therefore, lose the
opportunity to sell  the securities at  a desirable price.  In addition, in  the
event  that  a  borrower  of  securities would  file  for  bankruptcy  or become
insolvent, disposition of the securities may be delayed pending court action.
    

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

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

PORTFOLIO TURNOVER.   The Fund  does not  intend to  invest for  the purpose  of
seeking  short-term profits,  however securities in  its portfolio  will be sold
whenever the Fund's investment  adviser believes it is  appropriate to do so  in
light of the Fund's investment objective, without regard to the length of time a
particular security may have been held.

INVESTMENT LIMITATIONS

The Fund will not:

    - invest   in  stripped  mortgage  securities,  including  securities  which
      represent a share  of only  the interest  payments or  only the  principal
      payments from underlying mortgage related securities;

    - borrow   money   directly   or  through   reverse   repurchase  agreements
      (arrangements in  which  the  Fund  sells a  portfolio  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 net assets and pledge up to
      10% of the value of its total assets to secure such borrowings;

    - lend  any of its assets except portfolio securities up to one-third of the
      value of its total assets;

    - 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. With respect  to
      the  asset-backed securities,  the Fund will  treat the  originator of the
      asset  pool  as  the  company  issuing  the  securities  for  purposes  of
      determining compliance with this limitation.

                                       8

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

The Fund will not:

    - invest  more than 15% of its net  assets in securities which are illiquid,
      including repurchase  agreements providing  for  settlement in  more  than
      seven days after notice.

MANAGEMENT OF THE TRUST

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

INVESTMENT ADVISER.  Pursuant to an investment advisory contract with the Trust,
investment decisions for the Fund are  made by Federated Management, the  Fund's
investment  adviser (the "Adviser"),  subject to direction  by the Trustees. The
Adviser continually conducts  investment research and  supervision for the  Fund
and  is responsible for the purchase or sale of portfolio instruments, for which
it receives an annual fee from the Fund.
    ADVISORY FEES.  The Adviser receives an annual investment advisory fee equal
    to .60  of 1%  of  the Fund's  average daily  net  assets. The  Adviser  may
    voluntarily  choose to waive a portion of  its fee or reimburse the Fund for
    certain operating expenses. This does not include reimbursement to the  Fund
    of  any  expenses  incurred by  shareholders  who use  the  transfer agent's
    subaccounting facilities. The Adviser can terminate this voluntary waiver of
    its advisory fee at any  time in its sole  discretion. The Adviser has  also
    undertaken  to  reimburse  the  Fund for  operating  expenses  in  excess of
    limitations established by certain states.

transactions in  securities being  purchased or  sold, or  being considered  for
purchase  or sale, by the Fund; prohibit purchasing securities in initial public
offerings; and prohibit taking  profits on securities held  for less than  sixty

and could result in severe penalties.
    

DISTRIBUTION OF INSTITUTIONAL SHARES

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

   
SHAREHOLDER SERVICES.    The  Trust  has entered  into  a  Shareholder  Services
Agreement  with  Federated  Shareholder  Services,  a  subsidiary  of  Federated
Investors, under  which the  Trust may  make payments  up to  .25 of  1% of  the
average  daily net  asset value  of the  Trust, computed  at an  annual rate, to
obtain certain personal  services for  shareholders and  provide maintenance  of
shareholder  accounts.  From  time  to  time  and  for  such  periods  as deemed
appropriate, the amount stated above may be reduced voluntarily.
    

   
Under the Shareholder  Services Agreement, Federated  Shareholder Services  will
either   perform  shareholder   services  directly  or   will  select  financial
institutions to perform shareholder services.
    

                                       10

   
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  Trust  and
Federated Shareholder Services.
    

   
SUPPLEMENTAL  PAYMENTS TO  FINANCIAL INSTITUTIONS.   In addition  to payments to
financial institutions  under  the  Shareholder  Services  Agreement,  Federated
Securities  Corp. and Federated Shareholder Services, from their own assets, may
also pay  financial  institutions  supplemental  fees  for  the  performance  of
substantial   sales   services,   distribution-related   support   services,  or
shareholder services. The support may include sponsoring sales, educational  and
training seminars at recreational-type facilities for their employees, providing
sales  literature, and engineering computer software programs that emphasize the
attributes of the Trust. Such assistance  will be predicated upon the amount  of
Shares  the financial institution  sells or may  sell, and/or upon  the type and
nature of sales or marketing support furnished by the financial institution. Any
payments made by  the distributor may  be reimbursed by  the Trust's Adviser  or
it's affiliates.

ADMINISTRATIVE  SERVICES.   Federated Administrative  Services, a  subsidiary of
Federated Investors, provides administrative  personnel and services  (including
certain  legal and financial reporting services)  necessary to operate the Fund.
Federated Administrative Services provides these at an annual rate which relates
to the average aggregate daily net  assets of all funds advised by  subsidiaries
of Federated Investors (the "Federated Funds") as specified below:

INDEPENDENT  AUDITORS.  The independent auditors for  the Fund are Ernst & Young
LLP, Pittsburgh, Pennsylvania.
    

EXPENSES OF THE FUND AND INSTITUTIONAL SHARES

The Fund pays all  of its own  expenses. 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

                                       11

Trust with federal and state securities authorities, Trustees' fees, the cost of
meetings of Trustees, legal fees of the Trust, association membership dues,  and
such non-recurring and extraordinary items as may arise.

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

At  present, no expenses  are allocated to  the Shares as  a class. However, the
Trustees reserve the right to allocate certain expenses to holders of Shares  as
they  deem appropriate (the  "Class Expenses"). In any  case, the 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's net asset value per share fluctuates. The net asset value for  Shares
is  determined by adding the  interest of the Shares in  the market value of all
securities and other assets of the Fund, subtracting the interest of the  Shares
in  the liabilities of the  Fund and those attributable  to Shares, and dividing
the remainder by the total number of Shares outstanding. The net asset value for
Shares will exceed that of Institutional  Service Shares due to the variance  in
daily  net income realized by  each class as a  result of different distribution
charges incurred by  the classes. Such  variance will reflect  only accrued  net
income to which the shareholders of a particular class are entitled.

INVESTING IN INSTITUTIONAL SHARES
- --------------------------------------------------------------------------------

SHARE PURCHASES

Shares are sold on days on which the New York Stock Exchange is open. Shares may
be purchased either by wire or mail.

To  purchase Shares of the Fund, open an account by calling Federated Securities
Corp. Information  needed  to establish  the  account  will be  taken  over  the
telephone. The Fund reserves the right to reject any purchase request.

   
BY  WIRE.  To purchase Shares of the Fund by Federal Reserve wire, call the Fund
before 4:00  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)  on the  next business  day following  the order.  Federal funds
should be wired as  follows: Federated Services Company,  c/o State Street  Bank
and  Trust Company, Boston,  Massachusetts; Attention: EDGEWIRE;  For Credit to:
Federated ARMs
    

                                       12

Fund--Institutional Shares; Fund Number (this number can be found on the account
statement or by contacting the Fund);  Group Number or Order Number; Nominee  or
Institution  Name; ABA Number  011000028. Shares cannot be  purchased on days on
which the New York Stock Exchange is closed and on federal holidays  restricting
wire transfers.

   
BY  MAIL.  To purchase Shares of the Fund  by mail, send a check made payable to
Federated ARMs Fund--Institutional Shares  to: Federated Services Company,  P.O.
Box  8600,  Boston,  Massachusetts  02266-8600. Orders  by  mail  are considered
received after payment by check is converted by the transfer agent's bank, State
Street Bank, into federal  funds. This is normally  the next business day  after
State Street Bank receives the check.
    

MINIMUM INVESTMENT REQUIRED

The  minimum initial investment  in the Fund is  $25,000 plus any non-affiliated
bank or broker's fee, if  applicable. However, an account  may be opened with  a
smaller  amount as  long as the  $25,000 minimum  is reached within  90 days. An
institutional investor's minimum investment will be calculated by combining  all
accounts   it  maintains   with  the   Fund.  Accounts   established  through  a
non-affiliated bank or broker may be subject to a smaller minimum investment.

WHAT SHARES COST

Shares are sold  at their  net asset  value next  determined after  an order  is
received.  There is no sales charge imposed  by the Fund. Investors who purchase
Shares through a  non-affiliated bank  or broker  may be  charged an  additional
service fee by that bank or broker.

   
The  net asset value  is determined as of  the close of  trading ( normally 4:00
p.m., Eastern  time) on  the New  York Stock  Exchange, Monday  through  Friday,
except  on: (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 on which no Shares are tendered for redemption and no orders
to  purchase Shares are  received; and (iii) the  following holidays: New Year's
Day, Presidents' Day, Good  Friday, Memorial Day,  Independence Day, Labor  Day,
Thanksgiving Day, and Christmas Day.
    

EXCHANGING SECURITIES FOR INSTITUTIONAL SHARES

Investors  may exchange certain  U.S. government securities  or a combination of
securities and cash for Shares. The securities  and any cash must have a  market
value  of  at  least $25,000.  The  Fund  reserves the  right  to  determine the
acceptability of securities to be exchanged. Securities accepted by the Fund are
valued in the same manner as the Fund values its assets. Shareholders wishing to
exchange securities should first contact Federated Securities Corp.

SUBACCOUNTING SERVICES

Institutions are encouraged  to open  single master  accounts. However,  certain
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.  Institutions  holding Shares  in a  fiduciary, agency,  custodial, or
similar capacity 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 Shares.  This
prospectus

                                       13

should,  therefore, be read together with any agreement between the customer and
the 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.

Detailed  confirmations  of  each  purchase  or  redemption  are  sent  to  each
shareholder. Monthly confirmations are sent to report dividends paid during  the
month.

DIVIDENDS

Dividends are declared daily and paid monthly. Dividends are declared just prior
to  determining  net  asset value.  If  an order  for  Shares is  placed  on the
preceding business day, Shares purchased by wire begin earning dividends on  the
business  day wire payment  is received by  State Street Bank.  If the order for
Shares and payment by wire  are received on the  same day, Shares begin  earning
dividends  on the  next business  day. Shares  purchased by  check begin earning
dividends on the business day after the check is converted, upon instruction  of
the  transfer agent, into federal  funds. Dividends are automatically reinvested
on payment  dates in  additional Shares  of the  Fund unless  cash payments  are
requested by contacting the Fund.

CAPITAL GAINS

Capital  gains realized by the  Fund, if any, will  be distributed at least once
every twelve months.

REDEEMING INSTITUTIONAL SHARES
- --------------------------------------------------------------------------------

The Fund redeems Shares 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 by telephone request or by written request.

TELEPHONE REDEMPTION

Shareholders  may redeem their  Shares by telephoning the  Fund before 4:00 p.m.
(Eastern time). The proceeds will normally be wired the following business  day,
but  in no event longer than seven days later, to the shareholder's account at a
domestic commercial bank that is a member  of the Federal Reserve System. If  at
any  time the  Fund shall  determine it  necessary to  terminate or  modify this
method of redemption, shareholders would be promptly notified.

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

                                       14

In the  event  of drastic  economic  or  market changes,  the  shareholders  may
experience  difficulty in redeeming  by telephone. If such  a case should occur,
another method  of redemption,  such as  that discussed  in "Written  Requests,"
should be considered.

WRITTEN REQUESTS

   
Shares  may also be redeemed by sending a  written request to the Fund. Call the
Fund for specific instructions before redeeming by letter. The shareholder  will
be asked to provide in the request his name, the Fund name, the class of Shares,
his  account  number,  and  the  share  or  dollar  amount  requested.  If Share
certificates have been  issued, they  should be sent  by insured  mail with  the
written  request  to: Federated  Services Company,  500 Victory  Road-2nd Floor,
North Quincy, Massachusetts 02171.
    
   
SIGNATURES.  Shareholders requesting a redemption of any amount to be sent to an
address other than that on record with  the Fund, or a redemption payable  other
than  to the  shareholder of record  must have signatures  on written redemption
requests guaranteed by:
    

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

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

    - a  savings bank or savings and loan association whose deposits are insured
      by the Savings Association Insurance Fund ("SAIF"), 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 and its transfer agent reserve
the right to amend these standards at any time without notice.

RECEIVING PAYMENT.   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.

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  due  to
shareholder  redemptions.  This  requirement  does not  apply,  however,  if the
balance falls below $25,000 because of changes in the Fund's net asset value.

                                       15

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 Fund gives the  shareholder one vote in Trustee elections and
other matters submitted to shareholders for  vote. All shares of each  portfolio
in  the Trust have equal voting rights  except that, in matters affecting only a
particular Fund  or class,  only shares  of that  particular Fund  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 Fund shall  be called by the Trustees upon the  written
request of shareholders owning at least 10% of the Trust's outstanding shares of
all portfolios entitled to vote.
MASSACHUSETTS PARTNERSHIP LAW

Under  certain  circumstances, shareholders  may  be held  personally  liable as
partners under  Massachusetts law  for  acts or  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 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 from its assets.

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

FEDERAL INCOME TAX

The Fund  will pay  no  federal income  tax because  the  Fund expects  to  meet
requirements  of the Internal Revenue Code,  as amended, applicable to regulated
investment companies and to receive the  special tax treatment afforded to  such
companies.

The  Fund will be  treated as a  single, separate entity  for federal income tax
purposes so that  income (including  capital gains)  and losses  related by  the
Trust's  other portfolios, if  any, will not  be combined for  tax purposes with
those realized by the Fund.
                                       16

Unless otherwise exempt, shareholders are required to pay federal income tax  on
any  dividends and  other distributions, including  capital gains distributions,
received. This applies whether dividends and distributions are received in  cash
or  as additional Shares. Distributions representing long-term capital gains, if
any, will be taxable  to shareholders as long-term  capital gains no matter  how
long the shareholders have held the Shares.

PENNSYLVANIA CORPORATE AND PERSONAL PROPERTY TAXES

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

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

    - Shares  may be  subject to  personal property  taxes imposed  by counties,
      municipalities, and school  districts in Pennsylvania  to the extent  that
      the  Fund's portfolio securities  would be subject to  such taxes if owned
      directly by residents of those jurisdictions.

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

The yield of Institutional Shares is  calculated by dividing the net  investment
income  per share (as defined by  the Securities and Exchange Commission) earned
by Institutional Shares over a thirty-day period by the offering price per share
of Institutional Shares  on the  last day  of the  period. This  number is  then
annualized using semi-annual compounding. The yield does not necessarily reflect
income actually earned by Institutional Shares and, therefore, may not correlate
to the dividends or other distributions paid to shareholders.

The  Institutional  Shares are  sold  without any  sales  load or  other similar
non-recurring charges.

   
Total return and yield  will be calculated  separately for Institutional  Shares
and Institutional Service Shares.
    

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

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

   
The  Fund  also  offers another  class  of shares  called  Institutional Service
Shares. Institutional Service Shares  are sold to  banks and other  institutions
that  hold assets in an agency capacity  and rely upon the distribution services
provided by the distributor  for the marketing  of these shares,  as well as  to
retail  customers of  such institutions,  and are  subject to  a minimum initial
investment of $25,000. Institutional Service Shares are sold at net asset  value
and are distributed pursuant to a Rule 12b-1
    

                                       17

Plan  adopted by the Trust whereby the distributor is paid a fee of .25 of 1% of
the Institutional Service Shares' average net assets.

   
Shares and  Institutional Service  Shares are  subject to  certain of  the  same
expenses.  Expense differences  between Shares and  Institutional Service Shares
may affect the performance of each class.

FEDERATED ARMS FUND
NOTES TO FINANCIAL STATEMENTS
AUGUST 31, 1995
- --------------------------------------------------------------------------------

(1) ORGANIZATION

Federated  ARMs Fund (the "Fund") is registered under the Investment Company Act
of  1940,  as  amended  (the  "Act"),  as  a  diversified,  open-end  management
investment  company. The Fund offers two classes of shares: Institutional Shares
and Institutional Service Shares.

(2) SIGNIFICANT ACCOUNTING POLICIES

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

    INVESTMENT VALUATIONS--Short-term  securities with  remaining maturities  of
    sixty  days or less at the time of purchase may be valued at amortized cost,
    which approximates fair  market value.  All other securities  are valued  at
    prices provided by an independent pricing service.

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

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

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

   
    FEDERAL  TAXES--It is the Fund's policy to comply with the provisions of the
    Code applicable  to  regulated investment  companies  and to  distribute  to
    shareholders  each  year substantially  all of  its income.  Accordingly, no
    provisions for federal tax are necessary. At August 31, 1995, the Fund,  for
    federal  tax purposes, had a capital loss carryforward of $75,715,884, which
    will reduce the Fund's taxable income arising from future net realized  gain
    on investments, if any, to the extent
    

                                       24

FEDERATED ARMS FUND
- --------------------------------------------------------------------------------
    permitted  by the Code, and thus will reduce the amount of the distributions
    to shareholders which would  otherwise be necessary to  relieve the Fund  of
    any  liability  for federal  tax. Pursuant  to the  Code, such  capital loss
    carryforward will expire as follows:

                     <S>                   <C>
                          2001                $1,799,433
                          2002                $16,735,698

</TABLE>

    

   
    Additionally, net  capital losses  of  $9,722,167 attributable  to  security
    transactions  incurred after October 31, 1994  are treated as arising on the
    first day of the Fund's next taxable year.
    

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

   
    DOLLAR ROLL  TRANSACTIONS--The Fund  enters into  dollar roll  transactions,
    with respect to mortgage securities issued by GNMA, FNMA, and FHLMC in which
    the   Fund  sells   mortgage  securities   to  financial   institutions  and
    simultaneously agrees to accept substantially similar (same type, coupon and
    maturity) securities at a  later date at an  agreed upon price. Dollar  roll
    transactions  are short-term  financing arrangements  which will  not exceed
    twelve  months.  The  Fund  will   use  the  proceeds  generated  from   the
    transactions  to  invest in  short-term investments,  which may  enhance the
    Fund's current yield and total return.
    

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

REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
- --------------------------------------------------------------------------------

To the Trustees and Shareholders of
FEDERATED ARMs FUND:

   
We  have  audited  the  accompanying  statement  of  assets  and  liabilities of
Federated ARMs Fund, including  the portfolio of investments,  as of August  31,
1995,  and the  related statement  of operations  for the  year then  ended, the
statement of changes in net assets for each of the two years in the period  then
ended,  and the  financial highlights for  the periods  presented therein. These
financial statements  and financial  highlights are  the responsibility  of  the
Fund's  management.  Our  responsibility  is  to  express  an  opinion  on these
financial statements and financial highlights based on our audits.
    

   
We  conducted  our  audits  in  accordance  with  generally  accepted   auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance  about  whether  the  financial  statements  and  financial
highlights  are free of material misstatement. An audit includes examining, on a
test basis, evidence  supporting the  amounts and disclosures  in the  financial
statements.  Our  procedures included  confirmation  of securities  owned  as of
August 31, 1995, by correspondence with the custodian and brokers. An audit also
includes assessing the accounting principles used and significant estimates made
by  management,  as   well  as  evaluating   the  overall  financial   statement
presentation.  We believe  that our  audits provide  a reasonable  basis for our
opinion.
    

   
In our opinion, the  financial statements and  financial highlights referred  to
above  present  fairly,  in all  material  respects, the  financial  position of
Federated ARMs Fund at August  31, 1995, the results  of its operations for  the
year  then ended, the changes in its net assets for each of the two years in the
period then  ended,  and the  financial  highlights for  the  periods  presented
therein, in conformity with generally accepted accounting principles.
    

                                                               ERNST & YOUNG LLP

  Shareholder Services Fee...................................................      0.25%
        Total Operating Expenses (3)....................................................      0.80%
</TABLE>


(1) The management fee  has been reduced  to reflect the  voluntary waiver of  a
    portion  of the  management fee.  The adviser  can terminate  this voluntary
    waiver at any  time at its  sole discretion. The  maximum management fee  is
    0.60%.

(2) The maximum 12b-1 fee is 0.25%.

   
(3)  The  total operating  expenses in  the  table above  are based  on expenses
    expected during the fiscal year ending August 31, 1996. The total  operating
    expenses  were 0.80% for  the fiscal year  ended August 31,  1995, and would
    have been 1.23% absent the voluntary waivers of a portion of the  management
    fee and 12b-1 fee.
    

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

separate  portfolios  of securities.  The  shares in  any  one portfolio  may be
offered in separate classes. With respect to  this Fund, as of the date of  this
prospectus,  the Board of Trustees (the  "Trustees") has established two classes
of  shares,  Institutional  Service   Shares  and  Institutional  Shares.   This
prospectus  relates only to  Institutional Service Shares  (the "Shares") of the
Fund.
    
Shares of the Fund are designed to  give banks and other institutions that  hold
assets in an agency capacity and rely upon the distribution services provided by
the  distributor  for  the marketing  of  these  Shares, as  well  as  to retail
customers of such institutions, a  convenient means of accumulating an  interest
in a professionally managed, diversified portfolio which invests at least 65% of
the  value  of its  total assets  in  U.S. government  securities, all  of which
government securities will be adjustable  and floating rate mortgage  securities
which  are issued or guaranteed  as to payment of  principal and interest by the
U.S. government, its  agencies or  instrumentalities. In addition,  the Fund  is
designed   to  provide  an  appropriate   investment  for  particular  financial
institutions which  are  subject  to government  agency  regulations,  including
credit  unions,  savings associations,  and  national banks.  A  minimum initial
investment of $25,000 over a 90-day period is required.

   
Shares are currently sold and redeemed at  net asset value without a sales  load
imposed by the Fund.
    

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

INVESTMENT OBJECTIVE

The  investment objective  of the Fund  is to provide  current income consistent
with minimal  volatility  of principal.  Current  income includes,  in  general,
discount  earned  on U.S.  Treasury bills  and  agency discount  notes, interest
earned on mortgage related securities and other U.S. government securities,  and
short-term  capital gains.  The investment  objective cannot  be changed without
approval of shareholders. The Fund  anticipates that it will experience  minimal
volatility  of principal  due to the  frequent adjustments to  interest rates on
adjustable and floating rate mortgage  securities which comprise the  portfolio.
Of  course, there  can be no  assurance that the  Fund will be  able to maintain
minimal  volatility  of  principal  or  that  it  will  achieve  its  investment
objective.  The Fund endeavors to achieve  its investment objective, however, by
following the investment policies described in this prospectus.

INVESTMENT POLICIES

Except as otherwise noted,  the investment policies described  below may not  be
changed by the Trustees without shareholder approval.

The  Fund will limit its investments to those that are permitted for purchase by
federal savings  associations  pursuant  to applicable  rules,  regulations,  or
interpretations of the Office of Thrift Supervision and by federal credit unions
under   the  Federal   Credit  Union  Act   and  the   rules,  regulations,  and
interpretations of the National Credit Union Administration (the "NCUA"). Should
additional permitted investments  be allowed as  a result of  future changes  in
applicable regulations or federal laws, the

                                       3

Fund  reserves the right, without shareholder approval, to make such investments
consistent with  the Fund's  investment  objective, policies,  and  limitations.
Further,  should  existing statutes  or regulations  change so  as to  cause any
securities held by the Fund to become ineligible for purchase by federal savings
associations or federal credit unions, the Fund will dispose of those securities
at times advantageous to the Fund.

As operated within the above limitations, and pursuant to the Fund's  investment
policy,  which  may  be  changed  without  shareholder  approval,  to  limit its
investments to securities that are  appropriate direct investments for  national
banks, the Fund will also serve as an appropriate vehicle for a national bank as
an investment for its own account.

ACCEPTABLE  INVESTMENTS.  The Fund pursues its investment objective by investing
at least  65% of  the value  of its  total assets  in a  professionally  managed
portfolio of U.S. government securities. As a matter of investment policy, which
may  be  changed  without shareholder  approval,  all of  these  U.S. government
securities will be adjustable  and floating rate  mortgage securities which  are
issued  or  guaranteed as  to  payment of  principal  and interest  by  the U.S.
government, its agencies or instrumentalities.

The types  of mortgage  securities in  which  the Fund  may invest  include  the
following:

    - adjustable rate mortgage securities;

    - collateralized mortgage obligations;

    - other  securities  collateralized  by or  representing  interests  in real
      estate mortgages whose interest rates reset at periodic intervals and  are
      issued   or   guaranteed  by   the  U.S.   government,  its   agencies  or
      instrumentalities.

In addition  to the  securities described  above, the  Fund may  also invest  in
direct obligations of the U.S. Treasury, such as U.S. Treasury bills, notes, and
bonds,  as well as obligations of  U.S. government agencies or instrumentalities
which are not collateralized by or represent interests in real estate mortgages,
as described above.

   
The Fund may also invest in  mortgage related securities, as defined in  section
3(a)(41) of the Securities Exchange Act of 1934, as amended, which are issued by
private  entities such as investment banking  firms and companies related to the
construction industry. The privately issued mortgage related securities in which
the Fund may invest include:
    
    - privately issued securities which are collateralized by pools of mortgages
      in which  each mortgage  is  guaranteed as  to  payment of  principal  and
      interest by an agency or instrumentality of the U.S. government;

    - privately issued securities which are collateralized by pools of mortgages
      in  which payment of  principal and interest are  guaranteed by the issuer
      and such guarantee is collateralized by U.S. government securities; and

    - other privately issued securities  in which the  proceeds of the  issuance
      are  invested in mortgage-backed  securities and payment  of the principal
      and interest are supported by the credit of any agency or  instrumentality
      of the U.S. government.

                                       4

The  privately issued mortgage related securities provide for a periodic payment
consisting of  both  interest  and  principal. The  interest  portion  of  these
payments will be distributed by the Fund as income, and the capital portion will
be reinvested.

   
The  prices of fixed  income securities fluctuate inversely  to the direction of
interest rates.
    

   
ADJUSTABLE RATE MORTGAGE  SECURITIES ("ARMs").   ARMs are pass-through  mortgage
securities  with adjustable rather than fixed  interest rates. The ARMs in which
the  Fund  invests  are  issued  by  Government  National  Mortgage  Association
("GNMA"),  Federal National Mortgage Association ("FNMA"), and Federal Home Loan
Mortgage Corporation ("FHLMC") and are actively traded. The underlying mortgages
which collateralize ARMs  issued by  GNMA are  fully guaranteed  by the  Federal
Housing  Administration ("FHA")  or Veterans Administration  ("VA"), while those
collateralizing  ARMs  issued  by  FHLMC  or  FNMA  are  typically  conventional
residential  mortgages  conforming  to  strict  underwriting  size  and maturity
constraints.
    

   
Unlike conventional bonds,  ARMs pay back  principal over the  life of the  ARMs
rather  than at maturity.  Thus, a holder of  the ARMs, such  as the Fund, would
receive monthly scheduled  payments of  principal and interest  and may  receive
unscheduled   principal  payments   representing  payments   on  the  underlying
mortgages. At the time that a holder of the ARMs reinvests the payments and  any
unscheduled  prepayments of principal that it receives, the holder may receive a
rate of interest which is actually lower  than the rate of interest paid on  the
existing  ARMs. As a consequence, ARMs may be a less effective means of "locking
in" long-term interest rates than other types of U.S. government securities.
    

   
Not unlike  other U.S.  government securities,  the market  value of  ARMs  will
generally vary inversely with changes in market interest rates. Thus, the market
value  of ARMs generally  declines when interest rates  rise and generally rises
when interest rates decline.
    

   
While ARMs generally  entail less risk  of a decline  during periods of  rapidly
rising  rates, ARMs may  also have less potential  for capital appreciation than
other  similar  investments  (e.g.,  investments  with  comparable   maturities)
because, as interest rates decline, the likelihood increases that mortgages will
be   prepaid.  Furthermore,  if  ARMs  are  purchased  at  a  premium,  mortgage
foreclosures and unscheduled  principal payments may  result in some  loss of  a
holder's  principal investment to the extent of the premium paid. Conversely, if
ARMs are purchased at a discount, both  a scheduled payment of principal and  an
unscheduled prepayment of principal would increase current and total returns and
would  accelerate the  recognition of income,  which would be  taxed as ordinary
income when distributed to shareholders.
    

COLLATERALIZED  MORTGAGE  OBLIGATIONS  ("CMOs").    CMOs  are  bonds  issued  by
single-purpose,   stand-alone  finance  subsidiaries   or  trusts  of  financial
institutions, government agencies, investment  bankers, or companies related  to
the construction industry. CMOs purchased by the Fund may be:

    - collateralized  by pools of mortgages in which each mortgage is guaranteed
      as to payment of principal and interest by an agency or instrumentality of
      the U.S. government;

    - collateralized by pools  of mortgages  in which payment  of principal  and
      interest  is guaranteed by the issuer and such guarantee is collateralized
      by U.S. government securities; or

                                       5

    - securities in which the proceeds of the issuance are invested in  mortgage
      securities  and payment of the principal and interest are supported by the
      credit of an agency or instrumentality of the U.S. government.

The Fund will  only purchase  CMOs which  are investment  grade, as  rated by  a
nationally recognized statistical rating organization.

REAL  ESTATE MORTGAGE INVESTMENT  CONDUITS ("REMICs").   REMICs are offerings of
multiple class real  estate mortgage-backed securities  which qualify and  elect
treatment  as such  under provisions  of the  Internal Revenue  Code. Issuers of
REMICs may  take  several forms,  such  as trusts,  partnerships,  corporations,
associations or a segregated pool of mortgages. Once REMIC status is elected and
obtained,  the entity is not subject to federal income taxation. Instead, income
is passed through  the entity and  is taxed to  the person or  persons who  hold
interests  in the REMIC. A REMIC interest must consist of one or more classes of
"regular interests," some of which may offer adjustable rates (the type in which
the Fund primarily  invests), and  a single  class of  "residual interests."  To
qualify  as a REMIC,  substantially all of the  assets of the  entity must be in
assets directly or indirectly secured principally by real property.

   
REGULATORY COMPLIANCE.   In accordance  with the  Rules and  Regulations of  the
NCUA,  unless the purchase is made solely to reduce interest-rate risk, the Fund
will not invest in  any CMO or  REMIC security that meets  any of the  following
three  tests: (1) the CMO or REMIC has  an expected average life greater than 10
years; (2) the average life of the CMO or REMIC extends by more than four  years
assuming  an immediate and sustained  parallel shift in the  yield curve of plus
300 basis points, or shortens by more  than six years assuming an immediate  and
sustained  parallel shift in the  yield curve of minus  300 basis points; or (3)
the estimated change in the price of the  CMO or REMIC is more than 17%, due  to
an  immediate and sustained parallel  shift in the yield  curve of plus or minus
300 basis points.
    

Neither test (1)  nor (2) above  apply to  floating or adjustable  rate CMOs  or
REMICs  with all of the following characteristics:  (a) the interest rate of the
instrument is  reset at  least annually;  (b)  the interest  rate is  below  the
contractual  cap of the instrument; (c) the  instrument is tied to a widely-used
market rate; and (d) the instrument varies directly (not inversely) and is reset
in proportion with the index's changes.

The Fund may not purchase  a residual interest in a  CMO or REMIC. In  addition,
the  Fund will not purchase zero  coupon securities with maturities greater than
10 years.

   
RESETS.  The interest rates paid on the ARMs, CMOs, and REMICs in which the Fund
invests generally are readjusted or reset at intervals of one year or less to an
increment over  some  predetermined interest  rate  index. There  are  two  main
categories of indices: those based on U.S. Treasury securities and those derived
from  a calculated measure, such as a cost of funds index or a moving average of
mortgage rates. Commonly  utilized indices  include the  one-year and  five-year
constant  maturity Treasury Note rates, the  three-month Treasury Bill rate, the
180-day Treasury  Bill  rate,  rates on  longer-term  Treasury  securities,  the
National  Median Cost  of Funds, the  one-month or  three-month London Interbank
Offered Rate (LIBOR),  the prime rate  of a specific  bank, or commercial  paper
rates.  Some indices, such as the one-year constant maturity Treasury Note rate,
closely mirror changes in market
    

                                       6

interest rate levels. Others tend to lag changes in market rate levels and  tend
to be somewhat less volatile.

   
CAPS  AND FLOORS.  The underlying  mortgages which collateralize the ARMs, CMOs,
and REMICs in which the Fund invests will frequently have caps and floors  which
limit  the maximum amount by which the loan rate to the residential borrower may
change up or down: (1) per reset or adjustment interval and (2) over the life of
the loan.  Some  residential mortgage  loans  restrict periodic  adjustments  by
limiting  changes  in the  borrower's  monthly principal  and  interest payments
rather than limiting  interest rate changes.  These payment caps  may result  in
negative amortization.
    

The  value of mortgage securities  in which the Fund  invests may be affected if
market interest rates rise or fall faster and farther than the allowable caps or
floors on the underlying residential mortgage loans. An example of the effect of
caps and floors  on a residential  mortgage loan  may be found  in the  Combined
Statement  of  Additional Information.  Additionally,  even though  the interest
rates on the underlying residential  mortgages are adjustable, amortization  and
prepayments  may occur, thereby causing the effective maturities of the mortgage
securities in which the Fund invests to be shorter than the maturities stated in
the underlying mortgages.

TEMPORARY INVESTMENTS.  For  defensive purposes only, the  Fund may also  invest
temporarily  in cash and money market instruments during times of unusual market
conditions and  to  maintain liquidity.  Money  market instruments  may  include
obligations such as:

    - obligations  of the U.S. government  or its agencies or instrumentalities;
      and

    - repurchase agreements.

REPURCHASE AGREEMENTS.  Repurchase agreements  are arrangements in which  banks,
broker/dealers, and other recognized financial institutions sell U.S. government
securities  or other  securities to the  Fund and agree  at the time  of sale to
repurchase them at a mutually  agreed upon time and  price within one year  from
the  date  of acquisition.  To  the extent  that  the original  seller  does not
repurchase the securities from  the Fund, the Fund  could receive less than  the
repurchase price on any sale of such securities.

LENDING  OF PORTFOLIO SECURITIES.   In order to  generate additional income, the
Fund may lend portfolio securities  on a short-term or  a long-term basis 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
investment adviser has determined are creditworthy under guidelines  established
by  the Fund's Board of Trustees and will receive collateral in the form of cash
or U.S.  government securities  equal  to at  least 100%  of  the value  of  the
securities loaned.

   
There is the risk that when lending portfolio securities, the securities may not
be available to the Fund on a timely basis and the Fund may, therefore, lose the
opportunity  to sell the  securities at a  desirable price. In  addition, in the
event that  a  borrower  of  securities would  file  for  bankruptcy  or  become
insolvent, disposition of the securities may be delayed pending court action.
    

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

                                       7

securities with payment and delivery scheduled  for a future time. The  seller's
failure  to complete these  transactions may cause  the Fund to  miss a price or
yield considered to  be advantageous. Settlement  dates may be  a month or  more
after  entering into these transactions, and the market values of the securities
purchased may  vary from  the purchase  prices. Accordingly,  the Fund  may  pay
more/less than the market value of the securities on the settlement date.

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

PORTFOLIO TURNOVER.   The Fund  does not  intend to  invest for  the purpose  of
seeking  short-term profits,  however securities in  its portfolio  will be sold
whenever the Fund's investment  adviser believes it is  appropriate to do so  in
light of the Fund's investment objective, without regard to the length of time a
particular security may have been held.

INVESTMENT LIMITATIONS

The Fund will not:

    - invest   in  stripped  mortgage  securities,  including  securities  which
      represent a share  of only  the interest  payments or  only the  principal
      payments from underlying mortgage related securities;

    - borrow   money   directly   or  through   reverse   repurchase  agreements
      (arrangements in  which  the  Fund  sells a  portfolio  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 net assets and pledge up to
      10% of the value of its total assets to secure such borrowings;

    - lend  any of its assets except portfolio securities up to one-third of the
      value of its total assets; or

    - 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. With respect  to
      the  asset-backed securities,  the Fund will  treat the  originator of the
      asset  pool  as  the  company  issuing  the  securities  for  purposes  of
      determining compliance with this limitation.

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

    - invest  more than 15% of its net  assets in securities which are illiquid,
      including repurchase  agreements providing  for  settlement in  more  than
      seven days after notice.

MANAGEMENT OF THE TRUST

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

INVESTMENT ADVISER.  Pursuant to an investment advisory contract with the Trust,
investment decisions for the Fund are  made by Federated Management, the  Fund's
investment  adviser (the "Adviser"),  subject to direction  by the Trustees. The
Adviser continually conducts  investment research and  supervision for the  Fund
and  is responsible for the purchase or sale of portfolio instruments, for which
it receives an annual fee from the Fund.

    ADVISORY FEES.  The Adviser receives an annual investment advisory fee equal
    to .60  of 1%  of  the Fund's  average daily  net  assets. The  Adviser  may
    voluntarily  choose to waive a portion of  its fee or reimburse the Fund for
    certain operating expenses. This does not include reimbursement to the  Fund
    of  any  expenses  incurred by  shareholders  who use  the  transfer agent's
    subaccounting facilities. The Adviser can terminate this voluntary waiver of
    its advisory fee at any  time in its sole  discretion. The Adviser has  also
    undertaken  to  reimburse  the  Fund for  operating  expenses  in  excess of
    limitations established by certain states.

    ADVISER'S BACKGROUND.    Federated  Management, a  Delaware  business  trust
    organized  on April 11,  1989, is a registered  investment adviser under the

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

DISTRIBUTION OF INSTITUTIONAL SERVICE SHARES

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

   
DISTRIBUTION PLAN AND SHAREHOLDER SERVICES.   Under a distribution plan  adopted
in  accordance with Investment Company Act Rule 12b-1 (the "Distribution Plan"),
the Fund will pay to the distributor an amount, computed at an annual rate of up
to .25 of 1% of the average daily net asset value of the 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  services  or  distribution-related  support
services as agents for their clients or customers.
    

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 amount or may earn a profit  from future payments made by the Fund
under the Distribution Plan.

   
In addition, the Trust  has entered into a  Shareholder Services Agreement  with
Federated Shareholder Services, a subsidiary of Federated Investors, under which
the Trust may make payments up to .25 on 1% of the average daily net asset value
of  the Trust, computed at  an annual rate, to  obtain certain personal services
for shareholders and provide maintenance  of shareholder accounts. From time  to
    

                                       10

   
time  and for such periods as deemed appropriate, the amount stated above may be
reduced voluntarily.
    

   
Under the Shareholder  Services Agreement, Federated  Shareholder Services  will
either   perform  shareholder   services  directly  or   will  select  financial
institutions  to  perform  shareholder  services.  Financial  institutions  will
receive  fees  based  upon  shares  owned by  their  clients  or  customers. The
schedules of such fees and the basis upon  which such fees will be paid will  be
determined from time to time by the Trust and Federated Shareholder Services.
    

   
The Glass-Steagall Act limits the ability of a depository institution (such as a
commercial   bank  or  a  savings  association)  to  become  an  underwriter  or
distributor of securities.  In the  event the  Glass-Steagall Act  is deemed  to
prohibit  depository institutions from acting  in the capacities described above
or should Congress  relax current restrictions  on depository institutions,  the
Trustees will consider appropriate changes in the services.
    

State securities laws governing the ability of depository institutions to act as
underwriters or distributors of securities may differ from interpretations given
to  the Glass-Steagall Act and, therefore,  banks and financial institutions may
be required to register as dealers pursuant to state law.

   
SUPPLEMENTAL PAYMENTS  TO  FINANCIAL  INSTITUTIONS.   In  addition  to  periodic
payments  to financial institutions under  the Distribution Plan and Shareholder
Services  Agreement,  Federated  Securities  Corp.  and  Federated   Shareholder
Services,   from  their  own   assets,  may  also   pay  financial  institutions
supplemental  fees   for  the   performance  of   substantial  sales   services,
distribution-related  support services, or shareholder services. The support may
include sponsoring sales, educational and training seminars at recreational-type
facilities for  their employees,  providing  sales literature,  and  engineering
computer  software programs  that emphasize  the attributes  of the  Trust. Such
assistance  will  be  predicated  upon  the  amount  of  Shares  the   financial
institution  sells or  may sell,  and/or upon  the type  and nature  of sales or
marketing support furnished by the  financial institution. Any payments made  by
the distributor may be reimbursed by the Trust's Adviser or it's affiliates.
    

ADMINISTRATION OF THE FUND

ADMINISTRATIVE  SERVICES.   Federated Administrative  Services, a  subsidiary of
Federated Investors, provides administrative  personnel and services  (including
certain  legal and financial reporting services)  necessary to operate the Fund.
Federated Administrative Services provides these at an annual rate which relates
to the average aggregate daily net  assets of all funds advised by  subsidiaries
of Federated Investors (the "Federated Funds") as specified below:

                                       11

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 ("State Street Bank"),  Boston,
Massachusetts, is custodian for the securities and cash of the Fund.

   
TRANSFER  AGENT  AND DIVIDEND  DISBURSING  AGENT.   Federated  Services Company,
Boston Massachusetts, is  the transfer  agent for the  Shares of  the Fund,  and
dividend disbursing agent for the Fund.
    

INDEPENDENT  AUDITORS.  The independent auditors for  the Fund are Ernst & Young
LLP, Pittsburgh, Pennsylvania.

EXPENSES OF THE FUND AND INSTITUTIONAL SERVICE SHARES

The Fund pays all  of its own  expenses. 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, 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, which relates  to the  Shares. However, the
Trustees reserve the right to allocate certain expenses to holders of Shares  as
they  deem appropriate (the  "Class Expenses"). In any  case, the 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's net asset value per share fluctuates. The net asset value for  Shares
is  determined by adding the  interest of the Shares in  the market value of all
securities and other assets of the Fund, subtracting the interest of the  Shares
in  the liabilities of the  Fund and those attributable  to Shares, and dividing
the remainder by the total number of Shares outstanding. The net asset value for
Institutional Shares will exceed that of Shares due to the variance in daily net
income realized by  each class  as a  result of  different distribution  charges
incurred  by the classes. Such variance will  reflect only accrued net income to
which the shareholders of a particular class are entitled.

                                       12

INVESTING IN INSTITUTIONAL SERVICE SHARES
- --------------------------------------------------------------------------------

SHARE PURCHASES

Shares are sold on days on which the New York Stock Exchange is open. Shares may
be purchased either by wire or mail.

To purchase Shares of the Fund, open an account by calling Federated  Securities
Corp.  Information  needed  to establish  the  account  will be  taken  over the
telephone. The Fund reserves the right to reject any purchase request.

   
BY WIRE.  To purchase Shares of the Fund by Federal Reserve wire, call the  Fund
before  4:00 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)  on the  next business  day following  the order.  Federal  funds
should  be wired as  follows: Federated Services Company,  c/o State Street Bank
and Trust Company,  Boston, Massachusetts; Attention:  EDGEWIRE; For Credit  to:
Federated ARMs 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; ABA Number 011000028. Shares  cannot
be  purchased on  days on  which the New  York Stock  Exchange is  closed and on
federal holidays restricting wire transfers.
    

   
BY MAIL.  To purchase Shares of the  Fund by mail, send a check made payable  to
Federated ARMs Fund-Institutional Service Shares to: Federated Services Company,
P.O.  Box 8600, Boston, Massachusetts 02266-8600.  Orders by mail are considered
received after payment by check is converted by the transfer agent's bank, State
Street Bank, into federal  funds. This is normally  the next business day  after
State Street Bank receives the check.
    

MINIMUM INVESTMENT REQUIRED

The  minimum initial investment  in the Fund is  $25,000 plus any non-affiliated
bank or broker's fee, if  applicable. However, an account  may be opened with  a
smaller  amount as  long as the  $25,000 minimum  is reached within  90 days. An
institutional investor's minimum investment will be calculated by combining  all
accounts   it  maintains   with  the   Fund.  Accounts   established  through  a
non-affiliated bank or broker may be subject to a smaller minimum investment.

WHAT SHARES COST

Shares are sold  at their  net asset  value next  determined after  an order  is
received.  There is no sales charge imposed  by the Fund. Investors who purchase
Shares through a  non-affiliated bank  or broker  may be  charged an  additional
service fee by that bank or broker.

   
The  net asset  value is determined  as of  the close of  trading (normally 4:00
p.m., Eastern  time) on  the New  York Stock  Exchange, Monday  through  Friday,
except  on: (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 on which no Shares are tendered for redemption and no orders
to  purchase Shares are  received; and (iii) the  following holidays: New Year's
Day, Presidents' Day, Good  Friday, Memorial Day,  Independence Day, Labor  Day,
Thanksgiving Day, and Christmas Day.
    

                                       13

EXCHANGING SECURITIES FOR INSTITUTIONAL SERVICE SHARES

Investors  may exchange certain  U.S. government securities  or a combination of
securities and cash for Shares. The securities  and any cash must have a  market
value  of  at  least $25,000.  The  Fund  reserves the  right  to  determine the
acceptability of securities to be exchanged. Securities accepted by the Fund are
valued in the same manner as the Fund values its assets. Shareholders wishing to
exchange securities should first contact Federated Securities Corp.

SUBACCOUNTING SERVICES

Institutions are encouraged  to open  single master  accounts. However,  certain
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.  Institutions  holding Shares  in a  fiduciary, agency,  custodial, or
similar capacity 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 Shares.  This
prospectus  should, therefore, be  read together with  any agreement between the
customer and the  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.

Detailed  confirmations  of  each  purchase  or  redemption  are  sent  to  each
shareholder.  Monthly confirmations are sent to report dividends paid during the
month.

DIVIDENDS
Dividends are declared daily and paid monthly. Dividends are declared just prior
to determining  net  asset value.  If  an order  for  Shares is  placed  on  the
preceding  business day, Shares purchased by wire begin earning dividends on the
business day wire payment  is received by  State Street Bank.  If the order  for
Shares  and payment by wire  are received on the  same day, Shares begin earning
dividends on the  next business  day. Shares  purchased by  check begin  earning
dividends  on the business day after the check is converted, upon instruction of
the transfer agent, into federal  funds. Dividends are automatically  reinvested
on  payment dates  in additional  Shares of  the Fund  unless cash  payments are
requested by contacting the Fund.

CAPITAL GAINS

Capital gains realized by the  Fund, if any, will  be distributed at least  once
every twelve months.

REDEEMING INSTITUTIONAL SERVICE SHARES
- --------------------------------------------------------------------------------

The  Fund redeems Shares 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

                                       14

   
value.  Redemption requests must be  received in proper form  and can be made by
telephone request or by written request.
    

TELEPHONE REDEMPTION

Shareholders may redeem their  Shares by telephoning the  Fund before 4:00  p.m.
(Eastern  time). The proceeds will normally be wired the following business day,
but in no event longer than seven days later, to the shareholder's account at  a
domestic  commercial bank that is a member  of the Federal Reserve System. If at
any time  the Fund  shall determine  it necessary  to terminate  or modify  this
method of redemption, shareholders would be promptly notified.

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

In  the  event  of drastic  economic  or  market changes,  the  shareholders may
experience difficulty in redeeming  by telephone. If such  a case should  occur,
another  method of  redemption, such  as that  discussed in  "Written Requests,"
should be considered.

WRITTEN REQUESTS

   
Shares may also be redeemed by sending  a written request to the Fund. Call  the
Fund  for specific instructions before redeeming by letter. The shareholder will
be asked to provide in the request his name, the Fund name, the class of Shares,
his account  number,  and  the  share  or  dollar  amount  requested.  If  Share
certificates  have been  issued, they  should be sent  by insured  mail with the
written request  to: Federated  Services Company,  500 Victory  Road-2nd  Floor,
North Quincy, MA 02171.
    

   
SIGNATURES.  Shareholders requesting a redemption of any amount to be sent to an
address  other than that on record with  the Fund, or a redemption payable other
than to the  shareholder of record  must have signatures  on written  redemption
requests guaranteed by:
    

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

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

    - a savings bank or savings and loan association whose deposits are  insured
      by  the Savings Association Insurance Fund ("SAIF"), 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 and its transfer agent  reserve
the right to amend these standards at any time without notice.

RECEIVING  PAYMENT.   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.

                                       15

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  due to
shareholder redemptions.  This  requirement  does not  apply,  however,  if  the
balance  falls below $25,000 because  of changes in the  Fund's net asset value.
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 Fund gives the  shareholder one vote in Trustee elections  and
other  matters submitted to shareholders for  vote. All shares of each portfolio
in the Trust have equal voting rights  except that, in matters affecting only  a
particular  Fund or  class, only  shares of  that particular  Fund 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 Fund shall be  called by the Trustees upon the written
request of shareholders owning at least 10% of the Trust's outstanding shares of
all portfolios entitled to vote.

MASSACHUSETTS PARTNERSHIP LAW

Under certain  circumstances,  shareholders may  be  held personally  liable  as
partners  under  Massachusetts law  for  acts or  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 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 from its assets.

                                       16

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

FEDERAL INCOME TAX

The  Fund  will pay  no  federal income  tax because  the  Fund expects  to meet
requirements of the Internal Revenue  Code, as amended, applicable to  regulated
investment  companies and to receive the  special tax treatment afforded to such
companies.

The Fund will be  treated as a  single, separate entity  for federal income  tax
purposes  so that  income (including  capital gains)  and losses  related by the
Trust's other portfolios,  if any, 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, including  capital gains  distributions,
received.  This applies whether dividends and distributions are received in cash
or as additional Shares. Distributions representing long-term capital gains,  if
any,  will be taxable to  shareholders as long-term capital  gains no matter how
long the shareholders have held the Shares.

PENNSYLVANIA CORPORATE AND PERSONAL PROPERTY TAXES

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

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

    - Shares may  be subject  to personal  property taxes  imposed by  counties,
      municipalities,  and school districts  in Pennsylvania to  the extent that
      the Fund's portfolio securities  would be subject to  such taxes if  owned
      directly by residents of those jurisdictions.

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

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

From  time  to  time,  the  Fund  advertises  its  total  return  and  yield for
Institutional Service Shares.

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

The  yield of  Institutional Service  Shares is  calculated by  dividing the net
investment  income  per  share  (as  defined  by  the  Securities  and  Exchange
Commission)  earned by Institutional Service Shares  over a thirty-day period by
the offering price per share of Institutional Service Shares on the last day  of
the  period. This number  is then annualized  using semi-annual compounding. The
yield does  not  necessarily reflect  income  actually earned  by  Institutional
Service  Shares  and, therefore,  may not  correlate to  the dividends  or other
distributions paid to shareholders.

The Institutional  Service Shares  are  sold without  any  sales load  or  other
similar non-recurring charges.

                                       17

   
Total  return and yield will be  calculated separately for Institutional Service
Shares and Institutional Shares.
    

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

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

   
The Fund  also  offers another  class  of shares  called  Institutional  Shares.
Institutional  Shares  are  sold  primarily  to  accounts  for  which  financial
institutions act in a fiduciary or  agency capacity, and other accounts where  a
financial  institution maintains master accounts with an aggregate investment of
at least $400 million in certain  mutual funds which are advised or  distributed
by  affiliates  of  Federated  Investors.  Shares  are  also  made  available to
financial intermediaries, public, and  private organizations. A minimum  initial
investment of $25,000 over a 90-day period is required. Institutional Shares are
sold at net asset value and are distributed without a Rule 12b-1 Plan.
    

   
Shares  and Institutional  Shares are subject  to certain of  the same expenses.
Expense differences  between  Shares and  Institutional  Shares may  affect  the
performance of each class.
    

   
To  obtain more information and a prospectus for Institutional Shares, investors
may call 1-800-235-4669.

FEDERATED ARMS FUND
NOTES TO FINANCIAL STATEMENTS
AUGUST 31, 1995
- --------------------------------------------------------------------------------

(1) ORGANIZATION

Federated  ARMs Fund (the "Fund") is registered under the Investment Company Act
of  1940,  as  amended  (the  "Act"),  as  a  diversified,  open-end  management
investment  company. The Fund offers two classes of shares: Institutional Shares
and Institutional Service Shares.

(2) SIGNIFICANT ACCOUNTING POLICIES

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

    INVESTMENT VALUATIONS--Short-term  securities with  remaining maturities  of
    sixty  days or less at the time of purchase may be valued at amortized cost,
    which approximates fair  market value.  All other securities  are valued  at
    prices provided by an independent pricing service.

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

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

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

   
    FEDERAL  TAXES--It is the Fund's policy to comply with the provisions of the
    Code applicable  to  regulated investment  companies  and to  distribute  to
    shareholders  each  year substantially  all of  its income.  Accordingly, no
    provisions for federal tax are necessary. At August 31, 1995, the Fund,  for
    federal  tax purposes, had a capital loss carryforward of $75,715,884, which
    will reduce the Fund's taxable income arising from future net realized  gain
    on investments, if any, to the extent
    

                                       24

FEDERATED ARMS FUND
- --------------------------------------------------------------------------------
    permitted  by the Code, and thus will reduce the amount of the distributions
    to shareholders which would  otherwise be necessary to  relieve the Fund  of
    any  liability  for federal  tax. Pursuant  to the  Code, such  capital loss
    carryforward will expire as follows:

                     <S>                   <C>
                          2001              1,799,4$33

    Additionally, net  capital losses  of  $9,722,167 attributable  to  security
    transactions  incurred after October 31, 1994  are treated as arising on the
    first day of the Fund's next taxable year.
    

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

   
    DOLLAR ROLL  TRANSACTIONS--The Fund  enters into  dollar roll  transactions,
    with respect to mortgage securities issued by GNMA, FNMA, and FHLMC in which
    the   Fund  sells   mortgage  securities   to  financial   institutions  and
    simultaneously agrees to accept substantially similar (same type, coupon and
    maturity) securities at a  later date at an  agreed upon price. Dollar  roll
    transactions  are short-term  financing arrangements  which will  not exceed
    twelve  months.  The  Fund  will   use  the  proceeds  generated  from   the
    transactions  to  invest in  short-term investments,  which may  enhance the
    Fund's current yield and total return.
    

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

REPORT OF ERNST & YOUNG LLP, INDEPENDENT AUDITORS
- --------------------------------------------------------------------------------

To the Trustees and Shareholders of
FEDERATED ARMs FUND:

   
We  have  audited  the  accompanying  statement  of  assets  and  liabilities of
Federated ARMs Fund, including  the portfolio of investments,  as of August  31,
1995,  and the  related statement  of operations  for the  year then  ended, the
statement of changes in net assets for each of the two years in the period  then
ended,  and the  financial highlights for  the periods  presented therein. These
financial statements  and financial  highlights are  the responsibility  of  the
Fund's  management.  Our  responsibility  is  to  express  an  opinion  on these
financial statements and financial highlights based on our audits.
    

   
We  conducted  our  audits  in  accordance  with  generally  accepted   auditing
standards.  Those standards require that we plan and perform the audit to obtain
reasonable assurance  about  whether  the  financial  statements  and  financial
highlights  are free of material misstatement. An audit includes examining, on a
test basis, evidence  supporting the  amounts and disclosures  in the  financial
statements.  Our  procedures included  confirmation  of securities  owned  as of
August 31, 1995, by correspondence with the custodian and brokers. An audit also
includes assessing the accounting principles used and significant estimates made
by  management,  as   well  as  evaluating   the  overall  financial   statement
presentation.  We believe  that our  audits provide  a reasonable  basis for our
opinion.
    

   
In our opinion, the  financial statements and  financial highlights referred  to
above  present  fairly,  in all  material  respects, the  financial  position of
Federated ARMs Fund at August  31, 1995, the results  of its operations for  the
year  then ended, the changes in its net assets for each of the two years in the
period then  ended,  and the  financial  highlights for  the  periods  presented
therein, in conformity with generally accepted accounting principles.

  AGREEMENT made as of the 1st day of December, 1994, by and between those

having their principal office and place of business at Federated Investors
Tower, Pittsburgh, PA  15222-3779 (the "Trust"), on behalf of the portfolios
(individually referred to herein as a "Fund" and collectively as "Funds") of
the Trust, and FEDERATED SERVICES COMPANY, a Delaware business trust, having
its principal office and place of business at Federated Investors Tower,
Pittsburgh, Pennsylvania 15222-3779 (the "Company").
  WHEREAS, the Trust is registered as an open-end management investment
company under the Investment Company Act of 1940, as amended (the "1940 Act"),
with authorized and issued shares of capital stock or beneficial interest
("Shares"); and
  WHEREAS, the Trust may desire to retain the Company to provide certain
pricing, accounting and recordkeeping services for each of the Funds,
including any classes of shares issued by any Fund ("Classes") if so indicated
on Exhibit 1, and the Company is willing to furnish such services; and
  WHEREAS, the Trust may desire to appoint the Company as its transfer agent,
dividend disbursing agent if so indicated on Exhibit 1, and agent in
connection with certain other activities, and the Company desires to accept
such appointment; and
  WHEREAS, the Trust may desire to appoint the Company as its agent to

of qualified banks if so indicated on Exhibit 1, and the Company desires to
accept such appointment; and
  WHEREAS, from time to time the Trust may desire and may instruct the
Company to subcontract for the performance of certain of its duties and
responsibilities hereunder to State Street Bank and Trust Company or another
agent (the "Agent"); and
  WHEREAS, the words Trust and Fund may be used interchangeably for those
investment companies consisting of only one portfolio;
  NOW THEREFORE, in consideration of the premises and mutual covenants herein
contained, and intending to be legally bound hereby, the parties hereto agree
as follows:
SECTION ONE:  FUND ACCOUNTING.
ARTICLE 1.  APPOINTMENT.
  The Trust hereby appoints the Company to provide certain pricing and
accounting services to the Funds, and/or the Classes, for the period and on
the terms set forth in this Agreement.  The Company accepts such appointment
and agrees to furnish the services herein set forth in return for the
compensation as provided in Article 3 of this Section.
ARTICLE 2.  THE COMPANY'S  DUTIES.
  Subject to the supervision and control of the Trust's Board of Trustees or
Directors ("Board"), the Company will assist the Trust with regard to fund
accounting for the Trust, and/or the Funds, and/or the Classes, and in
connection therewith undertakes to perform the following specific services;
  A.  Value the assets of the Funds using: primarily, market quotations,
      including the use of matrix pricing, supplied by the independent pricing
      services selected by the Company in consultation with the adviser, or
      sources selected by the adviser, and reviewed by the board; secondarily,
      if a designated pricing service does not provide a price for a security
                              -2-
      which the Company believes should be available by market quotation, the
      Company may obtain a price by calling brokers designated by the
      investment adviser of the fund holding the security, or if the adviser
      does not supply the names of such brokers, the Company will attempt on
      its own to find brokers to price those securities; thirdly, for
      securities for which no market price is available, the Pricing Committee
      of the Board will determine a fair value in good faith.  Consistent with
      Rule 2a-4 of the 40 Act, estimates may be used where necessary or
      appropriate.  The Company's obligations with regard to the prices
      received from outside pricing services and designated brokers or other
      outside sources, is to exercise reasonable care in the supervision of
      the pricing agent.  The Company is not the guarantor of the securities
      prices received from such agents and the Company is not liable to the
      Fund for potential errors in valuing a Fund's assets or calculating the
      net asset value per share of such Fund or Class when the calculations
      are based upon such prices.   All of the above sources of prices used as
      described are deemed by the Company to be authorized sources of security
      prices.  The Company provides daily to the adviser the securities prices
      used in calculating the net asset value of the fund, for its use in
      preparing exception reports for those prices on which the adviser has
      comment.  Further, upon receipt of the exception reports generated by
      the adviser, the Company diligently pursues communication regarding
      exception reports with the designated pricing agents.

  B.  Determine the net asset value per share of each Fund and/or Class, at
      the time and in the manner from time to time determined by the Board and
      as set forth in the Prospectus and Statement of Additional Information
      ("Prospectus") of each Fund;
  C.  Calculate the net income of each of the Funds, if any;

                              -3-
  D.  Calculate capital gains or losses of each of the Funds resulting from
      sale or disposition of assets, if any;
  E.  Maintain the general ledger and other accounts, books and financial
      records of the Trust, including for each Fund, and/or Class, as required
      under Section 31(a) of the 1940 Act and the Rules thereunder in
      connection with the services provided by the Company;
  F.  Preserve for the periods prescribed by Rule 31a-2 under the 1940 Act the
      records to be maintained by Rule 31a-1 under the 1940 Act in connection
      with the services provided by the Company.  The Company further agrees
      that all such records it maintains for the Trust are the property of the
      Trust and further agrees to surrender promptly to the Trust such records
      upon the Trust's request;
  G.  At the request of the Trust, prepare various reports or other financial
      documents required by federal, state and other applicable laws and
      regulations; and
  H.  Such other similar services as may be reasonably requested by the Trust.
ARTICLE 3.  COMPENSATION AND ALLOCATION OF EXPENSES.
  A.  The Funds will compensate the Company for its services rendered pursuant
      to Section One of this Agreement in accordance with the fees agreed upon
      from time to time between the parties hereto.  Such fees do not include
      out-of-pocket disbursements of the Company for which the Funds shall
      reimburse the Company upon receipt of a separate invoice.  Out-of-pocket
      disbursements shall include, but shall not be limited to, the items
      agreed upon between the parties from time to time.
  B.  The Fund and/or the Class, and not the Company, shall bear the cost of:
      custodial expenses; membership dues in the Investment Company Institute
      or any similar organization; transfer agency expenses; investment
      advisory expenses; costs of printing and mailing stock certificates,
      Prospectuses, reports and notices; administrative expenses; interest on
      borrowed money; brokerage commissions; taxes and fees payable to
                              -4-

      Directors of the Trust; independent auditors expenses; Federated
      Administrative Services and/or Federated Administrative Services, Inc.

      for work performed related to the Trust, the Funds, or the Classes; law
      firm expenses; or other expenses not specified in this Article 3 which
      may be properly payable by the Funds and/or classes.
  C.  The compensation and out-of-pocket expenses shall be accrued by the Fund
      and shall be paid to the Company no less frequently than monthly, and
      shall be paid daily upon request of the Company.  The Company will
      maintain detailed information about the compensation and out-of-pocket
      expenses by Fund and Class.
  D.  Any schedule of compensation agreed to hereunder, as may be adjusted
      from time to time, shall be dated and signed by a duly authorized
      officer of the Trust and/or the Funds and a duly authorized officer of
      the Company.
  E.  The fee for the period from the effective date of this Agreement with
      respect to a Fund or a Class to the end of the initial month shall be
      prorated according to the proportion that such period bears to the full
      month period.  Upon any termination of this Agreement before the end of
      any month, the fee for such period shall be prorated according to the
      proportion which such period bears to the full month period.  For
      purposes of determining fees payable to the Company, the value of the
      Fund's net assets shall be computed at the time and in the manner
      specified in the Fund's Prospectus.
  F.  The Company, in its sole discretion, may from time to time subcontract
      to, employ or associate with itself such person or persons as the
      Company may believe to be particularly suited to assist it in performing
      services under this Section One.  Such person or persons may be third-
      party service providers, or they may be officers and employees who are
                              -5-
      employed by both the Company and the Funds.  The compensation of such
      person or persons shall be paid by the Company and no obligation shall
      be incurred on behalf of the Trust, the Funds, or the Classes in such
      respect.
SECTION TWO:  SHAREHOLDER RECORDKEEPING.

  As used throughout this Agreement, a "Proper Instruction" means a writing
signed or initialed by one or more person or persons as the Board shall have
from time to time authorized.  Each such writing shall set forth the specific
transaction or type of transaction involved.  Oral instructions will be deemed

ARTICLE 5.  DUTIES OF THE COMPANY.
  The Company shall perform the following services in accordance with Proper
Instructions as may be provided from time to time by the Trust as to any Fund:

                              -6-
      (1)  The Company shall receive orders and payment for the purchase of
           shares and promptly deliver payment and appropriate documentation
           therefore to the custodian of the relevant Fund, (the "Custodian").
           The Company shall notify the Fund and the Custodian on a daily
           basis of the total amount of orders and payments so delivered.
      (2)  Pursuant to purchase orders and in accordance with the Fund's
           current Prospectus, the Company shall compute and issue the
           appropriate number of Shares of each Fund and/or Class and hold
           such Shares in the appropriate Shareholder accounts.
      (3)  For certificated Funds and/or Classes, if a Shareholder or its
           agent requests a certificate, the Company, as Transfer Agent, shall
           countersign and mail by first class mail, a certificate to the
           Shareholder at its address as set forth on the transfer books of
           the Funds, and/or Classes, subject to any Proper Instructions
           regarding the delivery of certificates.
      (4)  In the event that any check or other order for the purchase of
           Shares of the Fund and/or Class is returned unpaid for any reason,
           the Company shall debit the Share account of the Shareholder by the
           number of Shares that had been credited to its account upon receipt
           of the check or other order, promptly mail a debit advice to the
           Shareholder, and notify the Fund and/or Class of its action.  In
           the event that the amount paid for such Shares exceeds proceeds of
           the redemption of such Shares plus the amount of any dividends paid
           with respect to such Shares, the Fund and/the Class or its
           distributor will reimburse the Company on the amount of such
           excess.
  B.  Distribution
      (1)  Upon notification by the Funds of the declaration of any
           distribution to Shareholders, the Company shall act as Dividend

           The Company shall prepare and mail or credit income, capital gain,
           or any other payments to Shareholders.  As the Dividend Disbursing
           Agent, the Company shall, on or before the payment date of any such
           distribution, notify the Custodian of the estimated amount required
           to pay any portion of said distribution which is payable in cash
           and request the Custodian to make available sufficient funds for
           the cash amount to be paid out.  The Company shall reconcile the
           amounts so requested and the amounts actually received with the
           Custodian on a daily basis.  If a Shareholder is entitled to
           receive additional Shares by virtue of any such distribution or
           dividend, appropriate credits shall be made to the Shareholder's
           account, for certificated Funds and/or Classes, delivered where
           requested; and
      (2)  The Company shall maintain records of account for each Fund and

           Shareholders as to the foregoing.

           directions and, if such redemption requests comply with the
           procedures as may be described in the Fund Prospectus or set forth

           therefor to the Custodian.  The Company shall notify the Funds on a
           daily basis of the total amount of redemption requests processed
           and monies paid to the Company by the Custodian for redemptions.
      (2)  At the appropriate time upon receiving redemption proceeds from the
           Custodian with respect to any redemption, the Company shall pay or
           cause to be paid the redemption proceeds in the manner instructed
           by the redeeming Shareholders, pursuant to procedures described in
           the then-current Prospectus of the Fund.
                              -8-
      (3)  If any certificate returned for redemption or other request for
           redemption does not comply with the procedures for redemption
           approved by the Fund, the Company shall promptly notify the
           Shareholder of such fact, together with the reason therefor, and
           shall effect such redemption at the price applicable to the date
           and time of receipt of documents complying with said procedures.

           number of Shares of the Fund and/or Class which are authorized,
           based upon data provided to it by the Fund, and issued and
           outstanding.  The Company shall also provide the Fund on a regular
           basis or upon reasonable request with the total number of Shares
           which are authorized and issued and outstanding, but shall have no
           obligation when recording the issuance of Shares, except as
           otherwise set forth herein, to monitor the issuance of such Shares
           or to take cognizance of any laws relating to the issue or sale of
           such Shares, which functions shall be the sole responsibility of
           the Funds.
      (2)  The Company shall establish and maintain records pursuant to
