                        SUMMARY OF INVESTMENT OBJECTIVES

           The  investment  objectives of the Funds are  summarized  below.  See
"Investment  Objectives  and  Policies"  beginning  on page 9 for more  detailed
information.

           PRIME MONEY MARKET FUND seeks to provide current income and stability
of principal by investing in a broad range of short-term instruments,  including
U.S.  Government  and  U.S.  bank  and  commercial  obligations  and  repurchase
agreements relating to such obligations.

           PRIME VALUE MONEY  MARKET  FUND seeks to provide  current  income and
stability of principal by investing in a portfolio  consisting  of a broad range
of  short-term  instruments,   including  U.S.  Government  and  U.S.  bank  and
commercial  obligations and repurchase  agreements relating to such obligations.
Under normal market conditions,  at least 25% of the Fund's total assets will be
invested  in  obligations  of issuers in the  banking  industry  and  repurchase
agreements relating to such obligations.

           GOVERNMENT  OBLIGATIONS  MONEY  MARKET FUND seeks to provide  current
income with  liquidity  and  security of  principal  by investing in a portfolio
consisting  of U.S.  Treasury  bills,  notes  and  other  obligations  issued or
guaranteed  by the  U.S.  Government,  its  agencies  or  instrumentalities  and
repurchase agreements relating to such obligations.

           CASH  MANAGEMENT  FUND seeks to provide current income with liquidity
and  security  of  principal  by  investing  in a portfolio  consisting  of U.S.
Treasury bills, notes and other obligations issued or guaranteed as to principal
and  interest by the U.S.  Government,  its  agencies or  instrumentalities  and
repurchase  agreements  relating  to such  obligations.  The Fund is designed to
provide a convenient means for the late day investment of short-term assets held
by  banks,  trust  companies,  corporations,  employee  benefit  plans and other
institutional investors.

           TREASURY  INSTRUMENTS  MONEY MARKET FUND II seeks to provide  current
income with  liquidity  and  security of  principal  by investing in a portfolio
consisting of U.S.  Treasury  bills,  notes and direct  obligations  of the U.S.
Treasury and repurchase agreements relating to direct Treasury obligations.

           TAX-FREE  MONEY  MARKET  FUND  seeks  to  provide  as high a level of
current  income  exempt from federal  taxation as is  consistent  with  relative
stability of principal by  investing  in a portfolio  consisting  of  short-term
tax-exempt   obligations  issued  by  state  and  local  governments  and  other
tax-exempt  securities which are considered "First Tier Eligible  Securities" as
defined in  "Investment  Objectives  and  Policies."  The Fund will not purchase
securities  the  income  from which may be a specific  tax  preference  item for
purposes of federal individual and corporate alternative minimum tax.

           MUNICIPAL  MONEY  MARKET  FUND  seeks to  provide  as high a level of
current  income  exempt from federal  taxation as is  consistent  with  relative
stability of principal by  investing  in a portfolio  consisting  of  short-term
tax-exempt   obligations  issued  by  state  and  local  governments  and  other
tax-exempt  securities which are considered "Eligible  Securities" as defined in
"Investment Objectives and Policies."

      There is no  assurance  that  the  Funds  will  achieve  their  respective
investment objectives.

                       BACKGROUND AND EXPENSE INFORMATION

this  Prospectus.  Each class  represents an equal, pro rata interest in a Fund.
Each Fund's other classes of shares have different  service and/or  distribution
fees and  expenses  from Class A Shares which would  affect the  performance  of
those classes of shares.  Investors may obtain information concerning the Funds'
other classes of shares by calling Lehman Brothers at 1-800-368-5556.

Fund would bear directly or indirectly.  For more complete  descriptions  of the

* The Expense Summary above has been restated to reflect  current  expected fees
  and the  Adviser's  and  Administrator's  voluntary  fee  waiver  and  expense
  reimbursement arrangements currently in effect.

         In order to  maintain a  competitive  expense  ratio,  the  Adviser and
Administrator  have voluntarily  agreed to waive fees and reimburse  expenses to
the extent  necessary  to maintain  an  annualized  expense  ratio at a level no
greater  than .18% of average  daily net assets with  respect to the Funds (.26%
with respect

                                        4

to the Cash Management Fund). The voluntary fee waiver and expense reimbursement
arrangements  described  above  will  not be  changed  unless  shareholders  are
provided at least 60 days' advance notice.  The maximum annual  contractual fees
payable to the Adviser and Administrator  total .30% of average daily net assets
of the Funds.  Absent fee  waivers and  expense  reimbursements,  the Total Fund
Operating Expenses of Class A Shares are expected to be as follows:

                       INVESTMENT OBJECTIVES AND POLICIES

         The  investment  objectives  and  general  policies  of each  Fund  are
described  below.  Specific  investment  techniques  that may be employed by the
Funds are described in a separate  section of this  Prospectus.  See  "Portfolio
Instruments  and  Practices."  Differences  in objectives and policies among the
Funds,  differences in the degree of acceptable risk and tax  considerations are
some of the factors that can be expected to affect the investment return of each
Fund. Because of such factors,  the performance  results of the Funds may differ
even though more than one Fund may utilize the same security selections.

                                        9


<PAGE>


         Unless  otherwise  stated,  the investment  objectives and policies set
forth in this  Prospectus are not fundamental and may be changed by the Board of
Trustees without  shareholder  approval.  If there is a change in the investment
objective and policies of any Fund,  shareholders  should  consider  whether the
Fund remains an appropriate  investment in light of their then-current financial
position and needs. The market value of certain  fixed-rate  obligations held by
the Funds will generally vary inversely with changes in market  interest  rates.
Thus,  the market value of these  obligations  generally  declines when interest
rates  rise and  generally  rises when  interest  rates  decline.  The Funds are
subject to  additional  investment  policies and  restrictions  described in the
Statement of Additional  Information,  some of which are fundamental and may not
be changed without shareholder approval.

         The  Funds  seek to  maintain  a net asset  value of $1.00  per  share,
although  there is no assurance  that they will be able to do so on a continuing
basis.  Each  Fund  operates  as a  diversified  investment  portfolio.  Certain
securities  held by the Funds may have remaining  maturities in excess of stated
limitations  discussed  below if  securities  provide for  adjustments  in their
interest  rates  not less  frequently  than  such  time  limitations.  Each Fund
maintains a dollar-weighted average portfolio maturity of 90 days or less.

         PRIME  MONEY  MARKET  FUND AND PRIME  VALUE  MONEY  MARKET FUND seek to
provide current income and stability of principal.  In pursuing their investment
objectives,  the  Funds  invest  in a broad  range  of  short-term  instruments,
including  U.S.  Government  and  U.S.  bank  and  commercial   obligations  and
repurchase  agreements  relating to such  obligations.  Prime Value Money Market
Fund may also invest in securities of foreign issuers. Each Fund invests only in
securities  that are  payable in U.S.  dollars  and that have (or,  pursuant  to
regulations  adopted by the SEC will be deemed to have) remaining  maturities of
thirteen months or less at the date of purchase by the Fund.

         Both  Funds  invest  in  securities  rated by the  "Requisite  NRSROs."
"Requisite  NRSROs" means (a) any two  nationally-recognized  statistical rating
organizations ("NRSROs") that have issued a rating with respect to a security or
class of debt obligations of an issuer,  or (b) one NRSRO, if only one NRSRO has
issued such a rating at the time that the Fund acquires the security. Currently,
there are six NRSROs: Standard & Poor's, a division of The McGraw-Hill Companies
("S&P"); Moody's Investors Service, Inc. ("Moody's");  Fitch Investors Services,
Inc.;  Duff and Phelps,  Inc.;  IBCA Limited and its affiliate,  IBCA,  Inc. and
Thomson  Bankwatch.  A  discussion  of the ratings  categories  of the NRSROs is
contained in the Appendix to the Statement of Additional Information.

         Prime  Money  Market  Fund will  limit  its  portfolio  investments  to
securities  that the Board of Trustees  determines  present minimal credit risks
and which are "First Tier Eligible Securities" at the time of acquisition by the
Fund. The term First Tier Eligible  Securities  includes securities rated by the
Requisite  NRSROs in the highest  short-term  rating  categories,  securities of
issuers that have  received  such rating with respect to other  short-term  debt
securities and comparable unrated securities.

         Prime Value Money Market Fund will limit its portfolio  investments  to
securities  that the Board of Trustees  determines  present minimal credit risks
and which are "Eligible  Securities" at the time of acquisition by the Fund. The
term Eligible  Securities  includes  securities rated by the Requisite NRSROs in
one of the two highest short-term rating categories,  securities of issuers that
have received such rating with respect to other  short-term  debt securities and
comparable unrated securities.

         Each Fund  generally  may not invest more than 5% of it total assets in
the  securities of any one issuer,  except for U.S.  Government  securities.  In
addition, Prime Value Money Market Fund may not invest more than 5% of its total
assets in Eligible Securities that have not received the highest rating from the
Requisite NRSROs and comparable  unrated  securities  ("Second Tier Securities")
and may  not  invest  more  than  1% of its  total  assets  in the  Second  Tier
Securities  of any one  issuer.  The Funds may invest  more than 5% (but no more
than 25%) of the then-current value of the Fund's total assets in the securities
of a single issuer for a period of up to three business days,  provided that (a)
the  securities  either  are  rated  by the  Requisite  NRSROs  in  the  highest
short-term  rating category or are securities of issuers that have received such
rating  with  respect to other  short-term  debt  securities  or are  comparable
unrated securities, and (b) the Fund does not make more than one such investment
at any one time.

                                       10


<PAGE>


          Each Fund may purchase obligations of issuers in the banking industry,
such as commercial paper,  notes,  certificates of deposit,  bankers acceptances
and time deposits and U.S. dollar denominated instruments issued or supported by
the credit of U.S.  (or foreign in the case of Prime Value  Money  Market  Fund)
banks or savings  institutions  having  total  assets at the time of purchase in
excess of $1 billion. The Funds may also make interest-bearing  savings deposits
in commercial and savings banks in amounts not in excess of 5% of their assets.

         GOVERNMENT  OBLIGATIONS  MONEY MARKET FUND,  CASH  MANAGEMENT  FUND AND
TREASURY  INSTRUMENTS Money Market Fund II seek to provide income with liquidity
and security of principal. Each Fund invests only in securities that are payable
in U.S. dollars and that have (or,  pursuant to regulations  adopted by the SEC,
will be deemed to have)  remaining  maturities of thirteen months or less at the
date  of  purchase  by the  Fund  (twelve  months  in  the  case  of  Government
Obligations Money Market Fund).

         Government  Obligations  Money  Market  Fund and Cash  Management  Fund
invest in obligations issued or guaranteed by the U.S. Government,  its agencies
or instrumentalities (in addition to direct Treasury obligations) and repurchase
agreements  relating to such  obligations.  Cash  Management Fund is designed to
provide a convenient means for the late day investment of short-term assets held
by  institutional  investors  and is not  intended to be a long-term  investment
vehicle.

         Treasury  Instruments  Money  Market  Fund II invests  solely in direct
obligations  of the U.S.  Treasury,  such as  Treasury  bills and notes,  and in
repurchase agreements relating to direct Treasury obligations. The Fund will not
purchase obligations of agencies or instrumentalities of the U.S. Government.

         TAX-FREE  MONEY  MARKET FUND AND  MUNICIPAL  MONEY  MARKET FUND seek to
provide  investors  with as high a level of current  income  exempt from federal
income tax as is consistent  with relative  stability of principal.  In pursuing
their investment objectives,  the Funds invest substantially all of their assets
in diversified  portfolios of short-term tax-exempt  obligations issued by or on
behalf of states, territories and possessions of the United States, the District
of Columbia, and their respective authorities,  agencies,  instrumentalities and
political  subdivisions  and  tax-exempt  derivative  securities  such as tender
option bonds,  participations,  beneficial  interests in trusts and  partnership
interests  (collectively  "Municipal  Obligations").  Each Fund  invests only in
securities  that have (or,  pursuant to regulations  adopted by the SEC, will be
deemed to have)  remaining  maturities of thirteen months or less at the date of
purchase  by the Fund.  The Funds will not  knowingly  purchase  securities  the
interest on which is subject to federal  income  tax.  Except  during  temporary
defensive periods, each Fund will invest substantially all, but in no event less
than 80%, of its net assets in Municipal Obligations. Tax-Free Money Market Fund
will not  invest in  securities  the income  from  which may be a  specific  tax
preference  item for purposes of federal  individual  and corporate  alternative
minimum  tax.  The  Funds  also  have  the  ability  to  enter  into  repurchase
agreements.  Absent emergency or extraordinary  circumstances,  however, neither
Fund  presently  intends  to  engage in  repurchase  transactions,  unless  such
transactions would not generate taxable income to such Funds.

         Both the  Tax-Free  Money Market Fund and  Municipal  Money Market Fund
purchase Municipal Obligations that present minimal credit risk as determined by
the  Adviser  pursuant to  guidelines  approved  by the Board of  Trustees.  The
Municipal Money Market Fund invests in Eligible  Securities  while the Tax- Free
Money Market Fund invests in only First Tier Eligible Securities.  The Funds may
hold uninvested cash reserves pending  investment or during temporary  defensive
periods,  including when suitable tax-exempt obligations are unavailable.  There
is no  percentage  limitation  on  the  amount  of  assets  which  may  be  held
uninvested. Uninvested cash reserves will not earn income.

         Although the Tax-Free Money Market Fund may invest more than 25% of its
net assets in (a) Municipal  Obligations whose issuers are in the same state and
(b) Municipal  Obligations the interest on which is paid solely from revenues of
similar  projects,  it does not presently intend to do so on a regular basis. To
the extent the Fund's assets are concentrated in Municipal  Obligations that are
payable from the revenues of similar  projects or are issued by issuers  located
in the same state,  the Fund will be subject to the peculiar risks  presented by
the laws and economic conditions relating to such states,  projects and bonds to
a greater extent than it would be if its assets were not so concentrated.

                       PORTFOLIO INSTRUMENTS AND PRACTICES

         Investment  strategies  that are  available  to the Funds are set forth
below.  Additional  information concerning certain of these strategies and their
related risks is contained in the Statement of Additional Information.

U.S. GOVERNMENT OBLIGATIONS

         Each Fund (other than Tax-Free  Money Market Fund and  Municipal  Money
Market  Fund)  may  purchase  obligations  issued  or  guaranteed  by  the  U.S.
Government and (except in the case of Treasury Instruments Money Market Fund II)
U.S. Government agencies and instrumentalities.  Securities issued or guaranteed
by the  U.S.  Government  or its  agencies  or  instrumentalities  include  U.S.
Treasury  securities,  which differ in interest  rates,  maturities and times of
issuance.  Treasury bills have initial maturities of one year or less;  Treasury
notes have initial  maturities of one to ten years; and Treasury bonds generally
have initial  maturities of greater than ten years.  Some obligations  issued or
guaranteed  by U.S.  Government  agencies  or  instrumentalities,  for  example,
Government  National  Mortgage  Association   pass-through   certificates,   are
supported  by the full faith and credit of the U.S.  Treasury;  others,  such as
those issued by the Federal  National  Mortgage  Association,  by  discretionary
authority of the U.S.  Government to purchase certain  obligations of the agency
or  instrumentality;  and  others,  such as those  issued  by the  Student  Loan
Marketing  Association,  only by the  credit of the  agency or  instrumentality.
These securities bear fixed,  floating or variable rates of interest.  While the
U.S.  Government  provides  financial support to such U.S.  Government-sponsored
agencies or instrumentalities,  no assurance can be given that it will always do
so,  since  it is not so  obligated  by  law.  The  Funds  will  invest  in such
securities only when they are satisfied that the credit risk with respect to the
issuer is minimal.

         Securities issued or guaranteed by the U.S. Government, its agencies or
instrumentalities have historically involved little risk of loss of principal if
held to maturity.  However,  due to fluctuations  in interest rates,  the market
value of the  securities may vary during the period an investor owns shares of a
Fund.

REPURCHASE AGREEMENTS

         The Funds may agree to purchase securities from financial  institutions
subject to the seller's  agreement to repurchase them at an agreed upon time and
price within one year from the date of  acquisition  ("repurchase  agreements").
The Funds  will not  invest  more  than 10% of the value of their net  assets in
repurchase  agreements  with terms which exceed  seven days.  The seller under a
repurchase  agreement  will be required to maintain the value of the  securities
subject  to the  agreement  at not less  than the  repurchase  price  (including
accrued interest). Default by or bankruptcy of the seller would, however, expose
the  Funds to  possible  loss  because  of  adverse  market  action  or delay in
connection with the disposition of the underlying obligations.

REVERSE REPURCHASE AGREEMENTS

         Each Fund may borrow  funds for  temporary  purposes by  entering  into
reverse  repurchase  agreements in accordance  with the investment  restrictions
described  below.  Pursuant to such  agreements,  the Funds would sell portfolio
securities to financial  institutions  and agree to repurchase them at an agreed
upon date and price. The Funds would consider  entering into reverse  repurchase
agreements to avoid  otherwise  selling  securities  during  unfavorable  market
conditions. Reverse repurchase agreements involve the risk that the market value
of the  securities  sold  by the  Funds  may  decline  below  the  price  of the
securities  the Funds  are  obligated  to  repurchase.  The Funds may  engage in
reverse repurchase agreements provided that the amount of the reverse repurchase
agreements and any other  borrowings  does not exceed  one-third of the value of
the Fund's total assets (including the amount borrowed) less liabilities  (other
than borrowings).

WHEN-ISSUED SECURITIES

         The Funds (other than Tax-Free  Money Market Fund and  Municipal  Money
Market Fund) may  purchase  securities  on a  "when-issued"  basis.  When-issued
securities are securities  purchased for delivery  beyond the normal  settlement
date at a stated price and yield. The Funds will generally not

                                       12


<PAGE>


pay for such  securities  or  start  earning  interest  on them  until  they are
received.  Securities  purchased on a when-issued basis are recorded as an asset
and are subject to changes in value based upon  changes in the general  level of
interest  rates.  The Funds  expect that  commitments  to  purchase  when-issued
securities will not exceed 25% of the value of their total assets absent unusual
market conditions.  The Funds do not intend to purchase  when-issued  securities
for speculative purposes but only in furtherance of their investment objectives.

ILLIQUID SECURITIES

         Prime Money Market Fund, Prime Value Money Market Fund,  Tax-Free Money
Market Fund and Municipal Money Market Fund will not knowingly  invest more than
10% of the value of their  total net assets in  illiquid  securities,  including
time deposits and  repurchase  agreements  having  maturities  longer than seven
days.  Securities that have readily  available market  quotations are not deemed
illiquid  for  purposes  of  this  limitation  (irrespective  of  any  legal  or
contractual  restrictions on resale). Each of the Funds may invest in commercial
obligations  issued in reliance on the so-called "private  placement"  exemption
from  registration  afforded by Section 4(2) of the  Securities  Act of 1933, as
amended ("Section 4(2) paper").  Each of the Funds may also purchase  securities
that are not registered under the Securities Act of 1933, as amended,  but which
can be sold to qualified institutional buyers in accordance with Rule 144A under
that Act  ("Rule  144A  securities").  Section  4(2) paper is  restricted  as to
disposition  under  the  federal  securities  laws,  and  generally  is  sold to
institutional investors such as the Funds who agree that they are purchasing the
paper for investment and not with a view to public  distribution.  Any resale by
the purchaser must be in an exempt  transaction.  Section 4(2) paper is normally
resold  to other  institutional  investors  like the  Fund  through  or with the
assistance of the issuer or investment  dealers who make a market in the Section
4(2) paper,  thus providing  liquidity.  Rule 144A securities  generally must be
sold to other  qualified  institutional  buyers.  If a particular  investment in
Section 4(2) paper or Rule 144A securities is not determined to be liquid,  that
investment  will be included  within the percentage  limitation on investment in
illiquid securities.

FOREIGN SECURITIES

         Prime Value Money Market Fund may invest substantially in securities of
foreign issuers,  including  obligations of foreign banks or foreign branches of
U.S. banks, and debt securities of foreign issuers,  where the Adviser deems the
instrument  to present  minimal  credit risks.  Investments  in foreign banks or
foreign  issuers   present   certain  risks,   including  those  resulting  from
fluctuations  in currency  exchange  rates,  revaluation of  currencies,  future
political  and economic  developments  and the possible  imposition  of currency
exchange  blockages  or other  foreign  governmental  laws or  restrictions  and
reduced  availability of public  information.  Foreign issuers are not generally
subject to uniform accounting,  auditing and financial reporting standards or to
other regulatory practices and requirements applicable to domestic issuers.

ZERO COUPON AND CAPITAL APPRECIATION BONDS

         The Funds may invest in zero  coupon and  capital  appreciation  bonds,
which are debt securities issued or sold at a discount from their face value and
which do not entitle  the holder to any  periodic  payment of interest  prior to
maturity or a specified  redemption  date (or cash payment date).  The amount of
the discount  varies  depending  on the time  remaining  until  maturity or cash
payment date,  prevailing  interest rates, the liquidity of the security and the
perceived credit quality of the issuer.  These securities may also take the form
of debt securities that have been stripped of their unmatured  interest coupons,
the coupons themselves or receipts or certificates representing interest in such
stripped  debt  obligations  or  coupons.  Discounts  with  respect to  stripped
tax-exempt  securities  or their  coupons may be taxable.  The market  prices of
capital appreciation bonds generally are more volatile than the market prices of
interest-bearing  securities  and are likely to  respond to a greater  degree to
changes  in  interest  rates than  interest-bearing  securities  having  similar
maturity and credit quality.

                                       13

U.S. TREASURY STRIPS

         The Prime Money Market Fund, Prime Value Money Market Fund,  Government
Obligations  Money Market Fund, Cash  Management  Fund and Treasury  Instruments
Money  Market Fund II may invest in  separately  traded  principal  and interest
components  of  securities  backed  by the full  faith  and  credit  of the U.S.
Treasury.  The principal and interest  components  of U.S.  Treasury  bonds with
remaining  maturities  of  longer  than ten  years  are  eligible  to be  traded
independently under the Separate Trading of Registered Interest and Principal of
Securities  ("STRIPS")  program.  Under the STRIPS  program,  the  principal and
interest components are separately issued by the U.S. Treasury at the request of
depository  financial  institutions,   which  then  trade  the  component  parts
separately.  Under the stripped bond rules of the Internal Revenue Code of 1986,
as amended (the "Code"),  investments  by the Funds in STRIPS will result in the
accrual of interest income on such  investments in advance of the receipt of the
cash  corresponding to such income. The interest component of STRIPS may be more
volatile  than  that of U.S.  Treasury  bills  with  comparable  maturities.  In
accordance with Rule 2a-7, the Funds' investments in STRIPS are limited to those
with maturity components not exceeding thirteen months.

LENDING OF PORTFOLIO SECURITIES

         Each Fund may lend portfolio securities up to one-third of the value of
its  total   assets  to  U.S.  and  foreign   broker/dealers,   banks  or  other
institutional  borrowers  of  securities  that the  Adviser has  determined  are
creditworthy  under guidelines  established by the Board of Trustees.  The Funds
will receive collateral in the form of cash, letters of credit, or securities of
the U.S.  Government or its agencies  equal to at least 100% of the value of the
securities owned.

VARIABLE AND FLOATING RATE SECURITIES

         The interest  rates payable on certain  securities in which Prime Money
Market Fund, Prime Value Money Market Fund, Government  Obligations Money Market
Fund,  Cash  Management  Fund,  Tax-Free  Money Market Fund and Municipal  Money
Market  Fund may invest are not fixed and may  fluctuate  based upon  changes in
market rates. A variable rate  obligation has an interest rate which is adjusted
at  predesignated  periods.  Interest on a floating rate  obligation is adjusted
whenever  there is a change in the market rate of interest on which the interest
rate  payable  is  based.  Tax-exempt  variable  or  floating  rate  obligations
generally  permit the holders of such obligations to demand payment of principal
from the issuer or a third party at stated intervals. Variable and floating rate
obligations  are less  effective  than  fixed rate  instruments  at locking in a
particular  yield.  Such  obligations  may  fluctuate  in value in  response  to
interest  rate changes if there is a delay  between  changes in market  interest
rates and the interest reset date for the obligation. The Funds will take demand
or reset  features  into  consideration  in  determining  the average  portfolio
duration of the Fund and the  effective  maturity of individual  securities.  In
addition,  the absence of an  unconditional  demand feature  exercisable  within
seven days will require a tax-exempt  variable or floating rate obligation to be
treated as illiquid for purposes of a Fund's limitation on illiquid investments.
The  failure of the  issuer or a third  party to honor its  obligations  under a
demand or put feature might also require a tax-exempt  variable or floating rate
obligation  to be treated as illiquid  for  purposes of a Fund's  limitation  on
illiquid investments.

TAX-EXEMPT COMMERCIAL PAPER

         Tax-Free  Money Market Fund and Municipal  Money Market Fund may invest
in tax-exempt  commercial paper.  Issues of commercial paper typically represent
short-term, unsecured, negotiable promissory notes. These obligations are issued
by state and local  governments  and their agencies to finance  working  capital
needs of  municipalities  or to provide interim  construction  financing and are
paid from general or specific revenues of municipalities or are re-financed with
long-term debt. In some cases,  tax-exempt commercial paper is backed by letters
of credit,  lending  agreements,  note  repurchase  agreements  or other  credit
facility  arrangements  offered by banks or other  institutions.  The Funds will
invest only in tax-exempt  commercial paper rated at least Prime-2 by Moody's or
A-2 by S&P.

MUNICIPAL OBLIGATIONS

         Tax-Free  Money Market Fund and Municipal  Money Market Fund may invest
in the Municipal Obligations described below.

         Municipal  Obligations.  Municipal Obligations include bonds, notes and
other instruments issued by or on behalf of states,  territories and possessions
of the United States  (including  the District of Columbia) and their  political
subdivisions,  agencies or  instrumentalities,  the interest on which is, in the
opinion of bond counsel,  exempt from regular federal income tax (i.e., excluded
from gross income for federal  income tax purposes  but not  necessarily  exempt
from the personal  income  taxes of any state or, with respect to the  Municipal
Money Market  Fund,  from the federal  alternative  minimum  tax).  In addition,
Municipal  Obligations  include  participation  interests in such securities the
interest on which is, in the opinion of bond  counsel for the issuers or counsel
selected by the Adviser,  exempt from regular federal income tax. The definition
of Municipal Obligations includes other types of securities that currently exist
or may be  developed  in the future and that are,  or will be, in the opinion of
counsel,  as described above,  exempt from regular federal income tax,  provided
that  investing  in such  securities  is  consistent  with a  Fund's  investment
objective and policies.

         The two principal classifications of Municipal Obligations which may be
held by the Funds are "general obligation"  securities and "revenue" securities.
General  obligation  securities  are secured by the issuer's  pledge of its full
faith,  credit  and taxing  power for the  payment of  principal  and  interest.
Revenue  securities are payable only from the revenues derived from a particular
facility  or class of  facilities,  or in some  cases,  from the  proceeds  of a
special  excise tax or other  specific  revenue  source  such as the user of the
facility being financed. Revenue securities include private activity bonds which
may be held by the  Municipal  Money  Market Fund and which are not payable from
the unrestricted  revenues of the issuer.  While some private activity bonds are
general  obligation  securities,  the  vast  majority  are  revenue  securities.
Consequently,  the credit quality of private  activity bonds is usually directly
related to the credit  standing of the corporate user of the facility  involved.
Each of the Municipal  Obligations  described  below may take the form of either
general obligation or revenue securities.

         Municipal  Obligations  are often  issued to obtain  funds for  various
public purposes, including the construction of a wide range of public facilities
such as bridges,  highways,  housing,  hospitals, mass transportation,  schools,
streets and water and sewer  works.  Other public  purposes for which  Municipal
Obligations may be issued include refunding outstanding  obligations,  obtaining
funds  for  general  operating  and  obtaining  funds  to lend to  other  public
institutions  and  facilities.  Municipal  Obligations  also include  industrial
development  bonds or, with respect to the Municipal Money Market Fund,  private
activity bonds, which are issued by or on behalf of public authorities to obtain
funds for privately-operated  housing facilities,  airport, mass transit or port
facilities,  sewage disposal,  solid waste disposal or hazardous waste treatment
or disposal  facilities and certain local  facilities  for water supply,  gas or
electricity.  In addition,  proceeds of certain industrial development bonds are
used  for the  construction,  equipment,  repair  or  improvement  of  privately
operated industrial or commercial  facilities.  The interest income from private
activity bonds may subject certain investors to the federal  alternative minimum
tax.

         Municipal Leases, Certificates of Participation and Other Participation
Interests.  The Funds  may  invest  in  municipal  leases  and  certificates  of
participation  in municipal  leases.  A municipal  lease is an obligation in the
form of a lease or  installment  purchase  which is  issued  by a state or local
government to acquire equipment and facilities.  Income from such obligations is
generally exempt from state and local taxes in the state of issuance.  Municipal
leases  frequently  involve  special risks not normally  associated with general
obligation or revenue bonds. Leases and installment purchase or conditional sale
contracts  (which  normally  provide  for  title  to the  leased  asset  to pass
eventually to the governmental  issuer) have evolved as a means for governmental
issuers to acquire property and equipment without meeting the constitutional and
statutory  requirements for the issuance of debt. The debt issuance  limitations
are  deemed  to be  inapplicable  because  of the  inclusion  in many  leases or
contracts of "non-appropriation" clauses that relieve the governmental issuer of
any obligation to make future  payments under the lease or contract unless money
is appropriated for such purpose by the appropriate legislative body on a yearly
or other periodic basis. In addition, such leases or contracts may be subject to
the  temporary  abatement of payments in the event the issuer is prevented  from
maintaining occupancy of the leased premises or utilizing the leased equipment.

                                       15


<PAGE>


Although the  obligation  may be secured by the leased  equipment or facilities,
the disposition of the property in the event of  nonappropriation or foreclosure
might  prove   difficult,   time   consuming  and  costly,   and  result  in  an
unsatisfactory or delayed recoupment of the Fund's original investment.

         Certificates  of  participation   represent   undivided   interests  in
municipal leases,  installment  purchase  agreements or other  instruments.  The
certificates  are typically issued by a trust or other entity which has received
an assignment  of the payments to be made by the state or political  subdivision
under such leases or installment purchase agreements.

         Certain  municipal lease  obligations and certificates of participation
may be deemed illiquid for the purpose of a Fund's  limitation on investments in
illiquid  securities.  Other  municipal lease  obligations  and  certificates of
participation  acquired by the Funds may be determined by the Adviser,  pursuant
to guidelines adopted by the Board of Trustees,  to be liquid securities for the
purpose of such  limitation.  In  determining  the liquidity of municipal  lease
obligations  and  certificates  of  participation,  the Adviser will  consider a
variety  of  factors  including  (a) the  willingness  of dealers to bid for the
security,  (b) the number of dealers  willing to purchase or sell the obligation
and the number of other potential buyers,  (c) the frequency of trades or quotes
for the obligation,  and (d) the nature of marketplace trades. In addition,  the
Adviser  will  consider  factors  unique to  particular  lease  obligations  and
certificates of participation affecting the marketability thereof. These include
the general  creditworthiness  of the issuer,  the  importance  of the  property
covered by the lease to the issuer and the likelihood that the  marketability of
the obligation will be maintained  throughout the time the obligation is held by
the Funds.

         The Funds may also  purchase  participations  in Municipal  Obligations
held by a commercial bank or other financial  institution.  Such  participations
provide  the  Funds  with  the  right to a pro rata  undivided  interest  in the
underlying Municipal  Obligations.  In addition,  such participations  generally
provide the Funds with the right to demand payment,  on not more than seven days
notice, of all or any part of a Fund's participation  interest in the underlying
Municipal Obligation, plus accrued interest. These demand features will be taken
into consideration in determining the effective maturity of such  participations
and the average  portfolio  duration of the Funds. The Funds will only invest in
such  participations  if, in the  opinion  of bond  counsel  for the  issuers or
counsel selected by the Adviser, the interest from such participations is exempt
from regular federal income tax.

         Municipal  Notes.  Municipal  Obligations  purchased  by the  Funds may
include  fixed-rate notes or variable- rate demand notes.  Such notes may not be
rated by credit rating  agencies,  but unrated notes purchased by the Funds will
be determined by the Adviser to be of comparable quality at the time of purchase
to rated instruments purchasable by the Funds. Where necessary to determine that
a note is an Eligible Security or First Tier Eligible  Security,  the Funds will
require the issuer's obligation to pay the principal of the note be backed by an
unconditional  bank letter or line of credit,  guarantee or  commitment to lend.
While  there may be no active  secondary  market  with  respect to a  particular
variable  rate demand note  purchased by the Funds,  the Funds may,  upon notice
specified in the note,  demand  payment of the principal of the note at any time
or during specified  periods not exceeding  thirteen months,  depending upon the
instrument  involved,  and may resell the note at any time to a third party. The
absence of such an active secondary market, however, could make it difficult for
the Funds to dispose  of a  variable  rate  demand  note if the  issuer  were to
default  on its  payment  obligation  or during  periods  that the Funds are not
entitled to exercise their demand rights, and the Funds could, for this or other
reasons, suffer losses to the extent of the default.

         Pre-Refunded   Municipal   Obligations.   The  Funds   may   invest  in
pre-refunded   Municipal   Obligations.   The   principal  of  and  interest  on
pre-refunded  Municipal Obligations are no longer paid from the original revenue
source for the Municipal  Obligations.  Instead,  the source of such payments is
typically an escrow fund  consisting of obligations  issued or guaranteed by the
U.S. Government.  The assets in the escrow fund are derived from the proceeds of
refunding  bonds  issued  by  the  same  issuer  as the  pre-refunded  Municipal
Obligations,  but  usually on terms more  favorable  to the  issuer.  Issuers of
Municipal  Obligations  use this  advance  refunding  technique  to obtain  more
favorable terms with respect to Municipal  Obligations which are not yet subject
to call or redemption by the issuer.  For example,  advance refunding enables an
issuer to refinance debt at lower market  interest  rates,  restructure  debt to
improve cash flow or eliminate restrictive covenants in the indenture or other

                                       16


<PAGE>


governing instrument for the pre-refunded Municipal Obligations. However, except
for a change in the revenue  source from which  principal and interest  payments
are made, the pre-refunded  Municipal  Obligations  remain  outstanding on their
original  terms until they mature or are redeemed by the issuer.  The  effective
maturity of pre-refunded  Municipal  Obligations  will be the redemption date if
the issuer has assumed an  obligation  or indicated its intention to redeem such
obligations on the redemption date. Pre-refunded Municipal Obligations are often
purchased at a price which represents a premium over their face value.

         Tender Option  Bonds.  The Funds may purchase  tender  option bonds.  A
tender  option  bond is a Municipal  Obligation  (generally  held  pursuant to a
custodial arrangement) having a relatively long maturity and bearing interest at
a fixed rate substantially higher than prevailing  short-term  tax-exempt rates,
that has been  coupled  with the  agreement  of a third  party,  such as a bank,
broker-dealer or other financial institution, pursuant to which such institution
grants the security holders the option, at periodic  intervals,  to tender their
securities  to  the  institution   and  receive  the  face  value  thereof.   As
consideration  for providing  the option,  the  financial  institution  receives
periodic fees equal to the difference  between the Municipal  Obligation's fixed
coupon rate and the rate, as determined by a remarketing  or similar agent at or
near the commencement of such period,  that would cause the securities,  coupled
with  the  tender  option,  to  trade  at or  near  par  on  the  date  of  such
determination.  Thus, after payment of this fee, the security holder effectively
holds a demand  obligation  that bears  interest  at the  prevailing  short-term
tax-exempt   rate.   The  Adviser  will   consider  on  an  ongoing   basis  the
creditworthiness of the issuer of the underlying  Municipal  Obligation,  of any
custodian  and of the third  party  provider  of the tender  option.  In certain
instances and for certain  tender option bonds,  the option may be terminable in
the event of a default in payment of  principal  or interest  on the  underlying
Municipal Obligations and for other reasons. Additionally, the above description
of tender  option  bonds is meant only to  provide  an  example of one  possible
structure of such  obligations,  and the Funds may purchase  tender option bonds
with   different   types  of  ownership,   payment,   credit  and/or   liquidity
arrangements.

                             INVESTMENT LIMITATIONS

         The Funds' investment  objectives and policies  described above are not
fundamental  and may be  changed  by the  Board of  Trustees  without  a vote of
shareholders.  If there  is a  change  in the  investment  objective  of a Fund,
shareholders should consider whether the Fund remains an appropriate  investment
in light of  their  then  current  financial  position  and  needs.  The  Funds'
investment   limitations   described  below  may  not  be  changed  without  the
affirmative vote of the holders of a majority of its outstanding  shares.  There
can be no assurance that the Funds will achieve their investment objectives.  (A
complete list of the  investment  limitations  that cannot be changed  without a
vote of  shareholders  is contained in the Statement of  Additional  Information
under "Investment Objectives and Policies.")

         The Funds may not:

         1. Borrow money,  except that a Fund may (i) borrow money for temporary
or emergency  purposes (not for leveraging or investment) from banks, or subject
to specific  authorization  by the SEC,  from funds advised by the Adviser or an
affiliate  of the  Adviser,  and (ii) engage in reverse  repurchase  agreements;
provided that (i) and (ii) in combination  do not exceed  one-third of the value
of the Fund's total assets  (including  the amount  borrowed)  less  liabilities
(other than borrowings).  The Funds may not mortgage,  pledge or hypothecate any
assets  except  in  connection  with  such  borrowings  and  reverse  repurchase
agreements and then only in amounts not exceeding  one-third of the value of the
particular  Fund's total assets at the time of such  borrowing (or, with respect
to the Cash  Management  Fund,  in  amounts  not in excess of the  lesser of the
dollar amounts  borrowed or one-third of the value of the Fund's total assets at
the time of such borrowing).  Additional  investments will not be made by a Fund
when borrowings exceed 5% of the Fund's assets.

         2. Purchase any  securities  which would cause 25% or more of the value
of its  total  assets  at the  time  of  such  purchase  to be  invested  in the
securities of one or more issuers conducting their principal business activities
in the same industry,  except that Prime Value Money Market Fund will invest 25%
or more of the  value of its total  assets  in  obligations  of  issuers  in the
banking industry or in obligations,  such as repurchase  agreements,  secured by
such  obligations  (unless  the  Fund  is in a  temporary  defensive  position);
provided  that  there is no  limitation  with  respect  to  investments  in U.S.
Government  securities  or,  in the case of Prime  Money  Market  Fund,  in bank
instruments issued by domestic banks.

                                       17


<PAGE>


         3.  Make  loans  except  that a Fund  may (i)  purchase  or  hold  debt
obligations in accordance with its investment objective and policies, (ii) enter
into repurchase  agreements for securities,  (iii) lend portfolio securities and
(iv) with the exception of Government  Obligations Money Market Fund, subject to
specific  authorization  by the SEC,  lend money to other  funds  advised by the
Adviser or an affiliate of the Adviser.

         Each Fund may, in the future, seek to achieve its investment  objective
by  investing  all of its assets in a no-load,  open-end  management  investment
company having the same investment  objective and policies and substantially the
same  investment  restrictions  as those  applicable to the Fund. In such event,
each Fund's investment  advisory agreement would be terminated.  Such investment
would be made only if the Trust's Board of Trustees  believes that the aggregate
per share expenses of each class of the Fund and such other  investment  company
will be less than or approximately equal to the expenses which each class of the
Fund  would  incur if the Fund were to  continue  to retain the  services  of an
investment  adviser  for the Fund and the assets of the Fund were to continue to
be invested directly in portfolio securities.

                        PURCHASE AND REDEMPTION OF SHARES

         To allow the  Adviser to manage the Funds  effectively,  investors  are
strongly  urged to initiate all  investments  or  redemptions  of Fund shares as
early in the day as possible and to notify  Lehman  Brothers at least one day in
advance of transactions in excess of $5 million.

PURCHASE PROCEDURES

         Shares of the  Funds  are sold at the net asset  value per share of the
Fund next determined after receipt of a purchase order by Lehman  Brothers,  the
Distributor of the Fund's shares.  Purchase  orders for shares are accepted only
on days on which both the New York Stock  Exchange and the Federal  Reserve Bank
of Boston are open for business and must be transmitted to Lehman  Brothers,  by
telephone at 1-800-851-3134 or through Lehman Brothers ExpressNET,  an automated
order entry system  designed  specifically  for the Trust ("LEX").  Purchases of
shares  will be  effective  and  dividends  will  begin to accrue on the date of
purchase if purchase orders comply with the following schedule.

         Payment for Fund shares may be made only in federal  funds  immediately
available to Boston Safe Deposit and Trust Company ("Boston Safe").  Payment for
orders  which are not received or accepted by Lehman  Brothers  will be returned
after prompt  inquiry to the sending  institution.  A Fund may in its discretion
reject any order for shares.  Any person  entitled to receive  compensation  for
selling or servicing shares of the Funds may receive different  compensation for

         The minimum aggregate initial investment by an institution in the Funds
is $1 million  (with not less than $25,000  invested in any one Fund);  however,
broker-dealers  and other  institutional  investors may set a higher minimum for
their customers.  High net worth investors may purchase shares of the Funds. The
minimum aggregate  initial  investment by a high net worth investor in the Funds
is $5 million. To reach the minimum Trust-wide initial investment,  purchases of
shares  may be  aggregated  over a period  of six  months.  There is no  minimum
subsequent investment.

REDEMPTION PROCEDURES

         Redemption  orders must be transmitted to Lehman  Brothers by telephone

* All times stated are Eastern time.

         Shares are  redeemed at the net asset  value per share next  determined
after Lehman Brothers' receipt of the redemption  order.  While the Funds intend
to use their best efforts to maintain  their net asset value per share at $1.00,
the proceeds  paid to an investor upon  redemption  may be more or less than the
amount  invested  depending  upon a  share's  net  asset  value  at the  time of
redemption.

         The Funds reserve the right to wire  redemption  proceeds  within seven
days after receiving the redemption order if, in the judgment of the Adviser, an
earlier payment could adversely affect the Funds. The Funds shall have the right
to redeem  involuntarily  shares in any  account at their net asset value if the
value of the account is less than $10,000  ($5,000,000 in the case of a high net
worth  investor)  after 60 days' prior written notice to the investor.  Any such
redemption  shall be effected  at the net asset value per share next  determined
after the redemption order is entered.  If during the 60-day period the investor
increases  the value of its account to the required  level,  no such  redemption
shall take place.  In addition,  the Funds may redeem  shares  involuntarily  or
suspend the right of redemption as permitted under the Investment Company Act of
1940,  as amended  (the "1940  Act"),  or under  certain  special  circumstances
described in the Statement of Additional  Information under "Additional Purchase
and Redemption Information."

         The ability to give  telephone  instructions  for the  redemption  (and
purchase or exchange) of shares is  automatically  established  on an investor's
account.  However,  the Funds  reserve  the right to refuse a  redemption  order
transmitted  by telephone if it is believed  advisable to do so.  Procedures for
redeeming  Fund shares by telephone may be modified or terminated at any time by
the Funds or Lehman Brothers.  In addition,  neither the Funds,  Lehman Brothers
nor First Data Investor Services Group, Inc. ("FDISG") will be responsible for

                                       19


<PAGE>


the  authenticity  of telephone  instructions  for the  purchase,  redemption or
exchange of shares where the instructions are reasonably believed to be genuine.
Accordingly,  the investor will bear the risk of loss. The Funds will attempt to
confirm that telephone  instructions are genuine and will use such procedures as
are considered reasonable, including the recording of telephone instructions. To
the  extent  that the Funds  fail to use  reasonable  procedures  to verify  the
genuineness of telephone instructions,  the Funds or their service providers may
be liable for such instructions that prove to be fraudulent or unauthorized.

EXCHANGE PROCEDURES

         The Exchange Privilege enables an investor to exchange shares of a Fund
without  charge for shares of the same class of other Funds which have different
investment objectives that may be of interest to investors.  To use the Exchange
Privilege,  exchange  instructions must be given to Lehman Brothers by telephone
or through LEX. See "Redemption  Procedures." In exchanging  shares, an investor
must meet the minimum initial  investment  requirement of the other Fund and the
shares  involved  must be  legally  available  for sale in the  state  where the
investor resides.  Before any exchange, the investor must also obtain and should
review  a copy of the  current  prospectus  of the  Funds.  Prospectuses  may be
obtained  from  Lehman  Brothers  by  calling  1-800-368-5556.  Shares  will  be
exchanged at the net asset value next  determined  after  receipt of an exchange
request in proper form. The exchange of shares of one Fund for shares of another
Fund is treated for federal income tax purposes as a sale of the shares given in
exchange by the investor and, therefore,  an investor may realize a taxable gain
or loss. The Funds reserve the right to reject any exchange  request in whole or
in part.  The Exchange  Privilege may be modified or terminated at any time upon
notice to investors.

VALUATION OF SHARES -- NET ASSET VALUE

         Each Fund's net asset value per share for purposes of pricing  purchase
and redemption orders is determined by the Fund's Administrator on each weekday,
with the exception of those holidays on which either the New York Stock Exchange
or the Federal  Reserve  Bank of Boston is closed,  according  to the  following
schedule.

* All times stated are Eastern time.

         Currently,  one or both of the New York Stock  Exchange and the Federal
Reserve Bank of Boston are closed on the customary national business holidays of
New Year's Day, Martin Luther King, Jr.'s Birthday  (observed),  Presidents' Day
(Washington's Birthday), Good Friday, Memorial Day, Independence Day, Labor Day,
Columbus Day (observed),  Veterans Day,  Thanksgiving Day and Christmas Day, and
on the

                                       20

preceding  Friday or  subsequent  Monday when one of these  holidays  falls on a
Saturday or Sunday,  respectively.  The net asset value per share of Fund shares
is calculated  separately  for each class by adding the value of all  securities
and other  assets  of the  Fund,  subtracting  class-specific  liabilities,  and
dividing the result by the total  number of the Fund's  outstanding  shares.  In
computing net asset value, each Fund uses the amortized cost method of valuation
as  described in the  Statement  of  Additional  Information  under  "Additional
Purchase  and  Redemption  Information."  A Fund's net asset value per share for
purposes of pricing purchase and redemption  orders is determined  independently
of the net asset values of the shares of each other Fund.

OTHER MATTERS

         Fund  shares  are  sold  and  redeemed  without  charge  by the  Funds.
Institutional  investors  purchasing  or holding Fund shares for their  customer
accounts  may  charge  customers  fees for cash  management  and other  services
provided  in  connection  with their  accounts.  A customer  should,  therefore,
consider the terms of its account with an  institution  before  purchasing  Fund
shares.  An  institution  purchasing  or redeeming  Fund shares on behalf of its
customers  is  responsible  for  transmitting   orders  to  Lehman  Brothers  in
accordance with its customer agreements.

                                    DIVIDENDS

         Investors of a Fund are entitled to dividends and distributions arising
only  from the net  investment  income  and  capital  gains,  if any,  earned on
investments  held by that Fund.  Each Fund's net  investment  income is declared
daily as a dividend  to shares  held of record at the close of  business  on the
date of  declaration.  Shares begin  accruing  dividends on the day the purchase
order for the shares is effective and continue to accrue  dividends  through the
day before such shares are redeemed. Dividends are paid monthly by wire transfer
within five  business  days after the end of the month or within  five  business
days after a redemption  of all of an investor's  shares of a particular  class.
The Funds do not expect to realize net long-term capital gains.

         Dividends  are  determined  in the same manner and are paid in the same
amount  for each Fund  share,  except  that  shares of each  class  bear all the
expenses associated with that specific class.

         Institutional investors may elect to have their dividends reinvested in
additional  full and fractional  shares of the same class of shares with respect
to which such  dividends  are  declared at the net asset value of such shares on
the  payment  date.  Reinvested  dividends  receive  the same tax  treatment  as
dividends paid in cash. Such election,  or any revocation thereof,  must be made
in  writing  to Lehman  Brothers,  260  Franklin  Street,  15th  Floor,  Boston,
Massachusetts 02110-9624,  and will become effective after its receipt by Lehman
Brothers, with respect to dividends paid.

         FDISG,  as Transfer  Agent,  will send each investor or its  authorized
representative  an annual statement  designating the amount of any dividends and
capital gains distributions, if any, made during each year and their federal tax
qualification.

                                      TAXES

         Each Fund  qualified in its last taxable year and intends to qualify in
future years as a  "regulated  investment  company"  under the Code. A regulated
investment  company is exempt from federal income tax on amounts  distributed to
its investors.

         Qualification  as a regulated  investment  company under the Code for a
taxable  year  requires,  among  other  things,  that a Fund  distribute  to its
investors at least 90% of its investment  company  taxable income for such year.
In  general,  a Fund's  investment  company  taxable  income will be its taxable
income  (including  dividends and short-term  capital gains,  if any) subject to
certain  adjustments and excluding the excess of any net long-term capital gains
for the taxable  year over the net  short-term  capital  loss,  if any, for such
year.  Each Fund  intends  to  distribute  substantially  all of its  investment
company taxable income each year. Such distributions will be taxable as ordinary
income to Fund investors who are not currently exempt from

                                       21


<PAGE>


federal  income taxes,  whether such income is received in cash or reinvested in
additional shares. It is anticipated that none of a Fund's distributions will be
eligible for the dividends received deduction for corporations. The Funds do not
expect to realize  long-term  capital gains and,  therefore,  do not contemplate
payment of any "capital gain dividends" as described in the Code.

         Dividends  derived  from  exempt-interest  income from  Tax-Free  Money
Market  Fund and  Municipal  Money  Market  Fund may be  treated  by the  Fund's
investors as items of interest  excludable from their gross income under Section
103(a) of the Code, unless under the circumstances  applicable to the particular
investor the exclusion would be disallowed.

         Municipal  Money Market Fund may hold  without  limit  certain  private
activity bonds issued after August 7, 1986.  Investors must include,  as an item
of  tax  preference,  the  portion  of  dividends  paid  by  the  Fund  that  is
attributable to interest on such bonds in determining liability (if any) for the
federal  alternative  minimum tax.  Noncorporate  taxpayers,  depending on their
individual tax status,  may be subject to  alternative  minimum tax at a blended
rate between 26% and 28%. Corporate  taxpayers may be subject to (1) alternative
minimum tax at a rate of 20% of the excess of their alternative  minimum taxable
income  ("AMTI")  over the  exemption  amount,  and (2) the  environmental  tax.
Corporate investors must also take all exempt-interest dividends into account in
determining   certain   adjustments   for   federal   alternative   minimum  and
environmental tax purposes.  The environmental tax applicable to corporations is
imposed at the rate of .12% on the excess of the corporation's  modified federal
alternative minimum taxable income over $2,000,000.

         To the extent,  if any,  dividends  paid to investors by Tax-Free Money
Market Fund or Municipal  Money  Market Fund are derived from taxable  income or
from long-term or short-term  capital  gains,  such dividends will not be exempt
from federal income tax,  whether such dividends are paid in the form of cash or
additional shares, and may also be subject to state and local taxes.

         In addition  to federal  taxes,  an  investor  may be subject to state,
local or foreign  taxes on payments  received from a Fund. A state tax exemption
may be  available  in some  states to the extent  distributions  of the Fund are
derived from  interest on certain U.S.  Government  securities  or on securities
issued by public  authorities  in the state.  The Funds will  provide  investors
annually with information about federal income tax consequences of distributions
made each year.  Investors should be aware of the application of their state and
local tax laws to investments in the Funds.

Investors  will be advised at least annually as to the federal income tax status
of distributions made to them each year.

         The  foregoing  discussion  is  only a  brief  summary  of  some of the
important  federal  tax  considerations  generally  affecting  a  Fund  and  its
shareholders.  No  attempt  is made to  present a  detailed  explanation  of the
federal,  state or local income tax  treatment of a Fund or its  investors,  and
this  discussion  is not  intended as a  substitute  for  careful tax  planning.
Accordingly,  potential investors in the Funds should consult their tax advisers
with  specific  reference  to their  own tax  situation.  See the  Statement  of
Additional Information for a further discussion of tax consequences of investing
in shares of the Funds.

                             MANAGEMENT OF THE FUNDS

         The business and affairs of the Funds are managed  under the  direction
of  the  Trust's  Board  of  Trustees.  The  Trustees  approve  all  significant
agreements  between the Trust and the persons or companies that furnish services
to the Funds, including agreements with its Distributor, Adviser, Administrator,
Transfer  Agent  and  Custodian.  The  day-to-day  operations  of the  Funds are
delegated to the Funds' Adviser and  Administrator.  The Statement of Additional
Information contains general background  information  regarding each Trustee and
executive officer of the Trust.

DISTRIBUTOR

         Lehman  Brothers,  located at 3 World Financial  Center,  New York, New
York 10285,  is the  Distributor  of each Fund's  shares.  Lehman  Brothers is a
wholly-owned  subsidiary of Lehman Brothers  Holdings Inc.  ("Holdings").  As of
November 30, 1995, FMR Corp. beneficially owned approximately 11.7%, Nippon Life
Insurance Company  beneficially  owned  approximately  5.0% and Prudential Asset
Management  beneficially  owned  approximately  5.0% of the  outstanding  voting
securities of Holdings. Lehman Brothers, a leading full-service investment firm,
meets the diverse  financial needs of individuals,  institutions and governments
around the world. Lehman Brothers has entered into a Distribution Agreement with
the Trust pursuant to which it has the responsibility for distributing shares of
the Funds.

         The Trust has adopted a Plan of  Distribution  with  respect to Class A
shares of the  Funds  pursuant  to Rule  12b-1  under the 1940 Act.  The Plan of
Distribution  does not  provide  for the  payment by the Funds of any Rule 12b-1
fees for  distribution  or shareholder  services for Class A shares but provides
that Lehman Brothers may make payments to assist in the  distribution of Class A
shares out of the other fees  received by it or its  affiliates  from the Funds,
its past profits or any other sources available to it.

INVESTMENT ADVISER -- LEHMAN BROTHERS GLOBAL ASSET MANAGEMENT INC.

         LBGAM,  located at 3 World Financial Center,  New York, New York 10285,
serves as each Fund's Investment Adviser. LBGAM is a wholly-owned  subsidiary of
Holdings.  LBGAM,  together  with  other  Lehman  Brothers  investment  advisory
affiliates,  serves as investment  adviser to  investment  companies and private
accounts  and has assets under  management  of  approximately  $11 billion as of
December 31, 1995.

         As  Adviser  to the Funds,  LBGAM  manages  each  Fund's  portfolio  in
accordance  with  its  investment  objective  and  policies,   makes  investment
decisions  for the Funds,  places  orders to purchase  and sell  securities  and
employs  professional  portfolio  managers and  securities  analysts who provide
research  services to the Funds. For its services LBGAM is entitled to receive a
monthly fee from each Fund at the annual rate of .20% of the value of the Fund's
average daily net assets.

ADMINISTRATOR AND TRANSFER AGENT -- FIRST DATA INVESTOR SERVICES GROUP, INC.

         FDISG (formerly named The Shareholder Services Group, Inc.), located at
One Exchange Place, 53 State Street, Boston, Massachusetts 02109, serves as each
Fund's  Administrator and Transfer Agent. FDISG is a wholly-owned  subsidiary of
First Data Corporation.  As Administrator,  FDISG calculates the net asset value
of each  Fund's  shares  and  generally  assists in all  aspects of each  Fund's
administration   and  operation.   As  compensation   for  FDISG's  services  as
Administrator,  FDISG is entitled to receive from each Fund a monthly fee at the
annual rate of .10% of the value of the Fund's  average daily net assets.  FDISG
is also  entitled  to receive a fee from the Funds for its  services as Transfer
Agent.  FDISG pays Boston Safe, each Fund's Custodian,  a portion of its monthly
administration fee for custody services rendered to the Funds.

         On  May  6,  1994,   FDISG   acquired   the  third  party  mutual  fund
administration  business of The Boston  Company  Advisors,  Inc.,  an  indirect,
wholly-owned  subsidiary of Mellon Bank  Corporation  ("Mellon").  In connection
with the  transaction,  Mellon  assigned  to FDISG  its  agreement  with  Lehman
Brothers (then named Shearson Lehman Brothers Inc.) that Lehman Brothers and its
affiliates,  consistent with their fiduciary duties and assuming certain service
quality   standards  are  met,  would   recommend   FDISG  as  the  provider  of
administration services to the Funds.

This duty to recommend expires on May 21, 2000.

CUSTODIAN -- BOSTON SAFE DEPOSIT AND TRUST COMPANY

         Boston Safe, a wholly-owned subsidiary of Mellon, located at One Boston
Place, Boston,  Massachusetts 02108, serves as each Fund's Custodian.  Under the
terms of the Stock Purchase  Agreement  dated  September 14, 1992 between Mellon
and Lehman Brothers (then named Shearson Lehman Brothers Inc.),  Lehman Brothers
agreed to recommend  Boston Safe as Custodian  of mutual funds  affiliated  with
Lehman  Brothers until May 21, 2000 to the extent  consistent with its fiduciary
duties and other applicable law.

                                       23

EXPENSES

         Each Fund bears all its own expenses.  A Fund's expenses include taxes,
interest,  fees and  salaries of the Trust's  trustees  and officers who are not
directors,  officers or employees of the Fund's service  contractors,  SEC fees,
state   securities   qualification   fees,   costs  of  preparing  and  printing
prospectuses for regulatory purposes and for distribution to investors, advisory
and administration fees, charges of the custodian, administrator, transfer agent
and dividend disbursing agent, certain insurance premiums,  outside auditing and
legal expenses,  costs of shareholder  reports and shareholder  meetings and any
extraordinary  expenses.  Each Fund also pays for brokerage fees and commissions
(if any) in connection  with the purchase and sale of portfolio  securities.  In
order to maintain a competitive  expense  ratio,  the Adviser and  Administrator
have  voluntarily  agreed to waive  fees and  reimburse  expenses  to the extent
necessary  to maintain an  annualized  expense  ratio at a level no greater than
 .18% of average daily net assets with respect to the Funds (.26% with respect to
the Cash Management Fund).  This voluntary waiver and reimbursement  arrangement
will not be changed  unless  investors  are  provided at least 60 days'  advance
notice. In addition,  these service providers have agreed to reimburse the Funds
to the extent  required by  applicable  state law for certain  expenses that are
described  in the  Statement  of  Additional  Information.  Any fees  charged by
Service  Organizations  or other  institutional  investors to their customers in
connection  with  investments  in Fund  shares  are not  reflected  in a  Fund's
expenses.

                             PERFORMANCE AND YIELDS

         From time to time, the "yields" and "effective  yields" with respect to
all Funds,  and  "tax-equivalent  yields" with respect to Tax-Free  Money Market
Fund and  Municipal  Money Market Fund,  may be quoted in  advertisements  or in
reports to shareholders. Yield quotations are computed separately for each class
of shares. The "yield" quoted in advertisements for a particular class of shares
refers to the income  generated by an investment in such shares over a specified
period (such as a seven-day period) identified in the advertisement. This income
is then  "annualized;" that is, the amount of income generated by the investment
during that period is assumed to be generated each such period over a 52-week or
one-year period and is shown as a percentage of the  investment.  The "effective
yield" is calculated  similarly  but, when  annualized,  the income earned by an
investment in a particular  class is assumed to be  reinvested.  The  "effective
yield" will be  slightly  higher  than the  "yield"  because of the  compounding
effect of this assumed reinvestment. The "tax-equivalent yield" demonstrates the
level of taxable yield necessary to produce an after-tax  yield  equivalent to a
Fund's  tax-free yield for each class of shares.  It is calculated by increasing
the yield  (calculated as above) by the amount  necessary to reflect the payment
of federal  taxes at a stated rate.  The  "tax-equivalent  yield" will always be
higher than the "yield."

         A Fund's  performance  may be compared to those of other  mutual  funds
with similar  objectives,  to other relevant indices, or to rankings prepared by
independent  services or other financial or industry  publications  that monitor
the performance of mutual funds. For example, such data are reported in national
financial publications such as Morningstar, Inc., Barron's, IBC/Donoghue's Money
Fund Report(R), The Wall Street Journal and The New York Times; reports prepared
by Lipper  Analytical  Services,  Inc.; and  publications of a local or regional
nature.

         A  Fund's  yield  figures  for  a  class  of  shares   represent   past
performance,  will fluctuate and should not be considered as  representative  of
future results. The yield of any investment is generally a function of portfolio
quality and  maturity,  type of  investment  and  operating  expenses.  Any fees
charged by  institutional  investors  directly to their  customers in connection
with  investments  in Fund  shares are not  reflected  in a Fund's  expenses  or
yields;  and, such fees, if charged,  would reduce the actual return received by
customers on their investments.  The methods used to compute a Fund's yields are
described in more detail in the Statement of Additional  Information.  Investors
may call 1-800-238-2560 to obtain current yield information.

                     DESCRIPTION OF SHARES AND MISCELLANEOUS

         The Trust is a Massachusetts business trust established on November 25,
1992. The Trust's Declaration of Trust authorizes the Board of Trustees to issue
an unlimited number of full and fractional shares of beneficial  interest in the
Trust  and to  classify  or  reclassify  any  unissued  shares  into one or more
additional  classes of shares.  The Trust is an open-end  management  investment
company,  which currently offers seven portfolios.  The Trust has authorized the
issuance  of seven  classes  of  shares  for  Prime  Value  Money  Market  Fund,
Government  Obligations  Money Market Fund and  Municipal  Money Market Fund and
four  classes of shares for Prime  Money  Market  Fund,  Cash  Management  Fund,
Treasury  Instruments  Money Market Fund II and Tax-Free  Money Market Fund. The
issuance  of separate  classes of shares is  intended  to address the  different
service needs of different types of investors.  The Declaration of Trust further
authorizes  the Trustees to classify or reclassify  any class of shares into one
or more sub-classes.

         The  Trust  does  not  presently  intend  to hold  annual  meetings  of
shareholders  except as required by the 1940 Act or other  applicable  law.  The
Trust will call a meeting of  shareholders  for the  purpose of voting  upon the
question of removal of a member of the Board of Trustees upon written request of
shareholders owning at least 10% of the outstanding shares of the Trust entitled
to vote.

         Each Fund share  represents  an equal,  proportionate  interest  in the
assets belonging to the Fund. Each share, which has a par value of $.001, has no
preemptive  or conversion  rights.  When issued for payment as described in this
Prospectus, Fund shares will be fully paid and non-assessable.

         Holders  of the Fund's  shares  will vote in the  aggregate  and not by
class on all matters, except where otherwise required by law and except when the
Board of Trustees  determines  that the matter to be voted upon affects only the
shareholders of a particular class. Further, shareholders of the Funds will vote
in the  aggregate  and not by portfolio  except as otherwise  required by law or
when the Board of Trustees  determines  that the matter to be voted upon affects
only the  interests  of the  shareholders  of a  particular  portfolio  (see the
Statement of Additional  Information  under "Additional  Description  Concerning
Fund Shares" for  examples  where the 1940 Act  requires  voting by  portfolio).
Shareholders  of the Trust are  entitled  to one vote for each full  share  held
(irrespective of class or portfolio) and fractional votes for fractional  shares
held. Voting rights are not cumulative;  and,  accordingly,  the holders of more
than 50% of the aggregate shares of the Trust may elect all of the trustees.

         For  information  concerning the redemption of Fund shares and possible
restrictions on their transferability, see "Purchase and Redemption of Shares."

                        SUMMARY OF INVESTMENT OBJECTIVES

         The  investment  objectives  of the Funds  are  summarized  below.  See
"Investment  Objectives  and  Policies"  beginning  on page 8 for more  detailed
information.

         PRIME MONEY MARKET FUND seeks to provide  current  income and stability
of principal by investing in a broad range of short-term instruments,  including
U.S.  Government  and  U.S.  bank  and  commercial  obligations  and  repurchase
agreements relating to such obligations.

         PRIME  VALUE  MONEY  MARKET  FUND seeks to provide  current  income and
stability of principal by investing in a portfolio  consisting  of a broad range
of  short-term  instruments,   including  U.S.  Government  and  U.S.  bank  and
commercial  obligations and repurchase  agreements relating to such obligations.
Under normal market conditions,  at least 25% of the Fund's total assets will be
invested  in  obligations  of issuers in the  banking  industry  and  repurchase
agreements relating to such obligations.

         GOVERNMENT  OBLIGATIONS  MONEY  MARKET  FUND seeks to  provide  current
income with  liquidity  and  security of  principal  by investing in a portfolio
consisting  of U.S.  Treasury  bills,  notes  and  other  obligations  issued or
guaranteed  by the  U.S.  Government,  its  agencies  or  instrumentalities  and
repurchase agreements relating to such obligations.

         TREASURY  INSTRUMENTS  MONEY  MARKET  FUND II seeks to provide  current
income with  liquidity  and  security of  principal  by investing in a portfolio
consisting of U.S.  Treasury  bills,  notes and direct  obligations  of the U.S.
Treasury and repurchase agreements relating to direct Treasury obligations.

         TAX-FREE  MONEY MARKET FUND seeks to provide as high a level of current
income exempt from federal taxation as is consistent with relative  stability of
principal  by  investing  in a portfolio  consisting  of  short-term  tax-exempt
obligations   issued  by  state  and  local  governments  and  other  tax-exempt
securities which are considered  "First Tier Eligible  Securities" as defined in
"Investment  Objectives and Policies." The Fund will not purchase securities the
income from which may be a specific tax preference  item for purposes of federal
individual and corporate alternative minimum tax.

         MUNICIPAL MONEY MARKET FUND seeks to provide as high a level of current
income exempt from federal taxation as is consistent with relative  stability of
principal  by  investing  in a portfolio  consisting  of  short-term  tax-exempt
obligations   issued  by  state  and  local  governments  and  other  tax-exempt
securities which are considered "Eligible  Securities" as defined in "Investment
Objectives and Policies."

         There is no  assurance  that the Funds will  achieve  their  respective
investment objectives.

                       BACKGROUND AND EXPENSE INFORMATION

         Each Fund currently  offers four classes of shares,  only one of which,
Class B Shares,  is offered by this Prospectus.  Each class represents an equal,
pro rata interest in a Fund.  Each Fund's other classes of shares have different
service  and/or  distribution  fees and expenses from Class B Shares which would
affect  the  performance  of those  classes  of  shares.  Investors  may  obtain
information  concerning the Funds' other classes by calling  Lehman  Brothers at
1-800-368-5556.

         The  purpose  of the  following  table  is to  assist  an  investor  in
understanding  the various  costs and  estimated  expenses that an investor in a
Fund would bear directly or  indirectly.  Certain  institutions  may also charge
their clients fees in connection with investments in Class B Shares,  which fees
are not  reflected in the table below.  For more  complete  descriptions  of the
various costs and expenses, see "Management of the Funds" in this Prospectus and
the Statement of Additional Information.

* The Expense Summary above has been restated to reflect  current  expected fees
  and the  Adviser's  and  Administrator's  voluntary  fee  waiver  and  expense
  reimbursement arrangements currently in effect.

         In order to  maintain a  competitive  expense  ratio,  the  Adviser and
Administrator  have voluntarily  agreed to waive fees and reimburse  expenses to
the extent  necessary  to maintain  an  annualized  expense  ratio at a level no
greater than .43% of average daily net assets (.18%  excluding  Rule 12b-1 fees)
with respect

                                        4

to the Funds.  The voluntary fee waiver and expense  reimbursement  arrangements
described above will not be changed unless shareholders are provided at least 60
days' advance notice. The maximum annual contractual fees payable to the Adviser
and  Administrator  total .30% of average daily net assets of the Funds.  Absent
fee waivers and expense  reimbursements,  the Total Fund  Operating  Expenses of
Class B Shares are expected to be as follows:

                                                    PERCENTAGE OF AVERAGE DAILY
                                                            NET ASSETS

Prime Money Market Fund                                        .60%
Prime Value Money Market Fund                                  .60%
Government Obligations Money Market Fund                       .69%

Municipal Money Market Fund                                    .67%

- ----------
EXAMPLE:  An investor would pay the following  expenses on a $1,000  investment,
assuming  (1) a 5%  annual  return  and (2)  redemption  at the end of each time
period with respect to the Class B Shares:

                   1 YEAR     3 YEARS      5 YEARS       10 YEARS

                       INVESTMENT OBJECTIVES AND POLICIES

         The  investment  objectives  and  general  policies  of each  Fund  are
described  below.  Specific  investment  techniques  that may be employed by the
Funds are described in a separate  section of this  Prospectus.  See  "Portfolio
Instruments  and  Practices."  Differences  in objectives and policies among the
Funds,  differences in the degree of acceptable risk and tax  considerations are
some of the factors that can be expected to affect the investment return of each
Fund. Because of such factors,  the performance  results of the Funds may differ
even though more than one Fund may utilize the same security selections.

         Unless  otherwise  stated,  the investment  objectives and policies set
forth in this  Prospectus are not fundamental and may be changed by the Board of
Trustees without  shareholder  approval.  If there is a change in the investment
objective and policies of any Fund,  shareholders  should  consider  whether the
Fund remains an appropriate  investment in light of their then-current financial
position and needs. The market value of certain  fixed-rate  obligations held by
the Funds will generally vary inversely with changes in market  interest  rates.
Thus,  the market value of these  obligations  generally  declines when interest
rates  rise and  generally  rises when  interest  rates  decline.  The Funds are
subject to  additional  investment  policies and  restrictions  described in the
Statement of Additional  Information,  some of which are fundamental and may not
be changed without shareholder approval.

                                        8

         The  Funds  seek to  maintain  a net asset  value of $1.00  per  share,
although  there is no assurance  that they will be able to do so on a continuing
basis.  Each  Fund  operates  as a  diversified  investment  portfolio.  Certain
securities  held by the Funds may have remaining  maturities in excess of stated
limitations  discussed  below if  securities  provide for  adjustments  in their
interest  rates  not less  frequently  than  such  time  limitations.  Each Fund
maintains a dollar-weighted average portfolio maturity of 90 days or less.

         PRIME  MONEY  MARKET  FUND AND PRIME  VALUE  MONEY  MARKET FUND seek to
provide current income and stability of principal.  In pursuing their investment
objectives,  the  Funds  invest  in a broad  range  of  short-term  instruments,
including  U.S.  Government  and  U.S.  bank  and  commercial   obligations  and
repurchase  agreements  relating to such  obligations.  Prime Value Money Market
Fund may also invest in securities of foreign issuers. Each Fund invests only in
securities  that are  payable in U.S.  dollars  and that have (or,  pursuant  to
regulations  adopted by the SEC will be deemed to have) remaining  maturities of
thirteen months or less at the date of purchase by the Fund.

         Both  Funds  invest  in  securities  rated by the  "Requisite  NRSROs."
"Requisite  NRSROs" means (a) any two  nationally-recognized  statistical rating
organizations ("NRSROs") that have issued a rating with respect to a security or
class of debt obligations of an issuer,  or (b) one NRSRO, if only one NRSRO has
issued such a rating at the time that the Fund acquires the security. Currently,
there are six NRSROs: Standard & Poor's, a division of The McGraw-Hill Companies
("S&P"); Moody's Investors Service, Inc. ("Moody's");  Fitch Investors Services,
Inc.;  Duff and Phelps,  Inc.;  IBCA Limited and its affiliate,  IBCA,  Inc. and
Thomson  Bankwatch.  A  discussion  of the ratings  categories  of the NRSROs is
contained in the Appendix to the Statement of Additional Information.

         Prime  Money  Market  Fund will  limit  its  portfolio  investments  to
securities  that the Board of Trustees  determines  present minimal credit risks
and which are "First Tier Eligible Securities" at the time of acquisition by the
Fund. The term First Tier Eligible  Securities  includes securities rated by the
Requisite  NRSROs in the highest  short-term  rating  categories,  securities of
issuers that have  received  such rating with respect to other  short-term  debt
securities and comparable unrated securities.

         Prime Value Money Market Fund will limit its portfolio  investments  to
securities  that the Board of Trustees  determines  present minimal credit risks
and which are "Eligible  Securities" at the time of acquisition by the Fund. The
term Eligible  Securities  includes  securities rated by the Requisite NRSROs in
one of the two highest short-term rating categories,  securities of issuers that
have received such ratings with respect to other  short-term debt securities and
comparable unrated securities.

         Each Fund  generally  may not invest more than 5% of it total assets in
the  securities of any one issuer,  except for U.S.  Government  securities.  In
addition, Prime Value Money Market Fund may not invest more than 5% of its total
assets in Eligible Securities that have not received the highest rating from the
Requisite NRSROs and comparable  unrated  securities  ("Second Tier Securities")
and may  not  invest  more  than  1% of its  total  assets  in the  Second  Tier
Securities  of any one  issuer.  The Funds may invest  more than 5% (but no more
than 25%) of the then-current value of the Fund's total assets in the securities
of a single issuer for a period of up to three business days,  provided that (a)
the  securities  either  are  rated  by the  Requisite  NRSROs  in  the  highest
short-term  rating category or are securities of issuers that have received such
rating  with  respect to other  short-term  debt  securities  or are  comparable
unrated securities, and (b) the Fund does not make more than one such investment
at any one time.

         Each Fund may purchase  obligations of issuers in the banking industry,
such as commercial paper,  notes,  certificates of deposit,  bankers acceptances
and time deposits and U.S. dollar denominated instruments issued or supported by
the credit of the U.S. (or foreign in the case of Prime Value Money Market Fund)
banks or savings  institutions  having  total  assets at the time of purchase in
excess of $1 billion. The Funds may also make interest-bearing  savings deposits
in commercial and savings banks in amounts not in excess of 5% of their assets.

         GOVERNMENT OBLIGATIONS MONEY MARKET FUND AND TREASURY INSTRUMENTS MONEY
MARKET FUND II seek to provide  income with liquidity and security of principal.
Each Fund invests only in securities  that are payable in U.S.  dollars and that
have (or,  pursuant to  regulations  adopted by the SEC, will be deemed to have)
remaining  maturities of thirteen  months or less at the date of purchase by the
Fund (twelve months in the case of Government Obligations Money Market Fund).

                                        9


<PAGE>


         Government  Obligations Money Market Fund invests in obligations issued
or  guaranteed by the U.S.  Government,  its agencies or  instrumentalities  (in
addition to direct Treasury  obligations) and repurchase  agreements relating to
such obligations.

         Treasury  Instruments  Money  Market  Fund II invests  solely in direct
obligations  of the U.S.  Treasury,  such as  Treasury  bills and notes,  and in
repurchase  agreements  relating to direct Treasury  obligations.  The Fund will
purchase obligations of agencies or instrumentalities of the U.S. Government.

         TAX-FREE  MONEY  MARKET FUND AND  MUNICIPAL  MONEY  MARKET FUND seek to
provide  investors  with as high a level of current  income  exempt from federal
income tax as is consistent  with relative  stability of principal.  In pursuing
their investment objectives,  the Funds invest substantially all of their assets
in diversified  portfolios of short-term tax-exempt  obligations issued by or on
behalf of states, territories and possessions of the United States, the District
of Columbia, and their respective authorities,  agencies,  instrumentalities and
political  subdivisions  and  tax-exempt  derivative  securities  such as tender
option bonds,  participations,  beneficial  interests in trusts and  partnership
interests  (collectively  "Municipal  Obligations").  Each Fund  invests only in
securities  that have (or,  pursuant to regulations  adopted by the SEC, will be
deemed to have)  remaining  maturities of thirteen months or less at the date of
purchase  by the Fund.  The Funds will not  knowingly  purchase  securities  the
interest on which is subject to federal  income  tax.  Except  during  temporary
defensive periods, each Fund will invest substantially all, but in no event less
than 80%, of its net assets in Municipal Obligations. Tax-Free Money Market Fund
will not  invest in  securities  the income  from  which may be a  specific  tax
preference  item for purposes of federal  individual  and corporate  alternative
minimum  tax.  The  Funds  also  have  the  ability  to  enter  into  repurchase
agreements.  Absent emergency or extraordinary  circumstances,  however, neither
Fund  presently  intends  to  engage in  repurchase  transactions,  unless  such
transactions would not generate taxable income to such Funds.

         Both the  Tax-Free  Money Market Fund and  Municipal  Money Market Fund
purchase Municipal Obligations that present minimal credit risk as determined by
the  Adviser  pursuant to  guidelines  approved  by the Board of  Trustees.  The
Municipal  Money Market Fund invests in Eligible  Securities  while the Tax-Free
Money Market Fund invests in only First Tier Eligible Securities.  The Funds may
hold uninvested cash reserves pending  investment or during temporary  defensive
periods,  including when suitable tax-exempt obligations are unavailable.  There
is no  percentage  limitation  on  the  amount  of  assets  which  may  be  held
uninvested. Uninvested cash reserves will not earn income.

         Although the Tax-Free Money Market Fund may invest more than 25% of its
net assets in (a) Municipal  Obligations whose issuers are in the same state and
(b) Municipal  Obligations the interest on which is paid solely from revenues of
similar  projects,  it does not presently intend to do so on a regular basis. To
the extent the Fund's assets are concentrated in Municipal  Obligations that are
payable from the revenues of similar  projects or are issued by issuers  located
in the same state,  the Fund will be subject to the peculiar risks  presented by
the laws and economic conditions relating to such states,  projects and bonds to
a greater extent than it would be if its assets were not so concentrated.

                       PORTFOLIO INSTRUMENTS AND PRACTICES

         Investment  strategies  that are  available  to the Funds are set forth
below.  Additional  information concerning certain of these strategies and their
related risks is contained in the Statement of Additional Information.

Market  Fund)  may  purchase  obligations  issued  or  guaranteed  by  the  U.S.
Government and (except in the case of Treasury Instruments Money Market Fund II)
U.S. Government agencies and instrumentalities.  Securities issued or guaranteed
by the  U.S.  Government  or its  agencies  or  instrumentalities  include  U.S.
Treasury securities,

                                       10

which differ in interest rates, maturities and times of issuance. Treasury bills
have  initial  maturities  of one  year or less;  Treasury  notes  have  initial
maturities  of one to ten years;  and  Treasury  bonds  generally  have  initial
maturities of greater than ten years.  Some obligations  issued or guaranteed by
U.S. Government agencies or instrumentalities,  for example, Government National
Mortgage Association pass-through certificates,  are supported by the full faith
and credit of the U.S.  Treasury;  others,  such as those  issued by the Federal
National Mortgage Association, by discretionary authority of the U.S. Government
to purchase certain  obligations of the agency or  instrumentality;  and others,
such as those  issued by the Student  Loan  Marketing  Association,  only by the
credit of the agency or instrumentality.  These securities bear fixed,  floating
or variable  rates of interest.  While the U.S.  Government  provides  financial
support to such U.S.  Government-sponsored  agencies  or  instrumentalities,  no
assurance  can be given that it will always do so,  since it is not so obligated
by law. The Funds will invest in such  securities  only when they are  satisfied
that the credit risk with respect to the issuer is minimal.

         Securities issued or guaranteed by the U.S. Government, its agencies or
instrumentalities have historically involved little risk of loss of principal if
held to maturity.  However,  due to fluctuations  in interest rates,  the market
value of the  securities may vary during the period an investor owns shares of a
Fund.

REPURCHASE AGREEMENTS

         The Funds may agree to purchase securities from financial  institutions
subject to the seller's  agreement to repurchase them at an agreed upon time and
price within one year from the date of  acquisition  ("repurchase  agreements").
The Funds  will not  invest  more  than 10% of the value of their net  assets in
repurchase  agreements  with terms which exceed  seven days.  The seller under a
repurchase  agreement  will be required to maintain the value of the  securities
subject  to the  agreement  at not less  than the  repurchase  price  (including
accrued interest). Default by or bankruptcy of the seller would, however, expose
the  Funds to  possible  loss  because  of  adverse  market  action  or delay in
connection with the disposition of the underlying obligations.

REVERSE REPURCHASE AGREEMENTS

         Each Fund may borrow  funds for  temporary  purposes by  entering  into
reverse  repurchase  agreements in accordance  with the investment  restrictions
described  below.  Pursuant to such  agreements,  the Funds would sell portfolio
securities to financial  institutions  and agree to repurchase them at an agreed
upon date and price. The Funds would consider  entering into reverse  repurchase
agreements to avoid  otherwise  selling  securities  during  unfavorable  market
conditions. Reverse repurchase agreements involve the risk that the market value
of the  securities  sold  by the  Funds  may  decline  below  the  price  of the
securities  the Funds  are  obligated  to  repurchase.  The Funds may  engage in
reverse repurchase agreements provided that the amount of the reverse repurchase
agreements and any other  borrowings  does not exceed  one-third of the value of
the Fund's total assets (including the amount borrowed) less liabilities  (other
than borrowings).

WHEN-ISSUED SECURITIES

         The Funds (other than Tax-Free  Money Market Fund and  Municipal  Money
Market Fund) may  purchase  securities  on a  "when-issued"  basis.  When-issued
securities are securities  purchased for delivery  beyond the normal  settlement
date at a stated  price and  yield.  The Funds will  generally  not pay for such
securities or start earning interest on them until they are received. Securities
purchased  on a  when-issued  basis are  recorded as an asset and are subject to
changes in value based upon changes in the general level of interest rates.  The
Funds expect that commitments to purchase when-issued securities will not exceed
25% of the value of their total assets absent  unusual  market  conditions.  The
Funds do not intend to purchase when-issued  securities for speculative purposes
but only in furtherance of their investment objectives.

ILLIQUID SECURITIES

         Prime Money Market Fund, Prime Value Money Market Fund,  Tax-Free Money
Market Fund and Municipal Money Market Fund will not knowingly  invest more than
10% of the value of their  total net assets in  illiquid  securities,  including
time deposits and repurchase agreements having maturities longer than seven

                                       11


<PAGE>


days.  Securities that have readily  available market  quotations are not deemed
illiquid  for  purposes  of  this  limitation  (irrespective  of  any  legal  or
contractual  restrictions on resale). Each of the Funds may invest in commercial
obligations  issued in reliance on the so-called "private  placement"  exemption
from  registration  afforded by Section 4(2) of the  Securities  Act of 1933, as
amended ("Section 4(2) paper").  Each of the Funds may also purchase  securities
that are not registered under the Securities Act of 1933, as amended,  but which
can be sold to qualified institutional buyers in accordance with Rule 144A under
that Act  ("Rule  144A  securities").  Section  4(2) paper is  restricted  as to
disposition  under  the  federal  securities  laws,  and  generally  is  sold to
institutional investors such as the Funds who agree that they are purchasing the
paper for investment and not with a view to public  distribution.  Any resale by
the purchaser must be in an exempt  transaction.  Section 4(2) paper is normally
resold  to other  institutional  investors  like the  Fund  through  or with the
assistance of the issuer or investment  dealers who make a market in the Section
4(2) paper,  thus providing  liquidity.  Rule 144A securities  generally must be
sold to other  qualified  institutional  buyers.  If a particular  investment in
Section 4(2) paper or Rule 144A securities is not determined to be liquid,  that
investment  will be included  within the percentage  limitation on investment in
illiquid securities.

FOREIGN SECURITIES

         Prime Value Money Market Fund may invest substantially in securities of
foreign issuers,  including  obligations of foreign banks or foreign branches of
U.S. banks, and debt securities of foreign issuers,  where the Adviser deems the
instrument  to present  minimal  credit risks.  Investments  in foreign banks or
foreign  issuers   present   certain  risks,   including  those  resulting  from
fluctuations  in currency  exchange  rates,  revaluation of  currencies,  future
political  and economic  developments  and the possible  imposition  of currency
exchange  blockages  or other  foreign  governmental  laws or  restrictions  and
reduced  availability of public  information.  Foreign issuers are not generally
subject to uniform accounting,  auditing and financial reporting standards or to
other regulatory practices and requirements applicable to domestic issuers.

ZERO COUPON AND CAPITAL APPRECIATION BONDS

         The Funds may invest in zero  coupon and  capital  appreciation  bonds,
which are debt securities issued or sold at a discount from their face value and
which do not entitle  the holder to any  periodic  payment of interest  prior to
maturity or a specified  redemption  date (or cash payment date).  The amount of
the discount  varies  depending  on the time  remaining  until  maturity or cash
payment date,  prevailing  interest rates, the liquidity of the security and the
perceived credit quality of the issuer.  These securities may also take the form
of debt securities that have been stripped of their unmatured  interest coupons,
the coupons themselves or receipts or certificates representing interest in such
stripped  debt  obligations  or  coupons.  Discounts  with  respect to  stripped
tax-exempt  securities  or their  coupons may be taxable.  The market  prices of
capital appreciation bonds generally are more volatile than the market prices of
interest-bearing  securities  and are likely to  respond to a greater  degree to
changes  in  interest  rates than  interest-bearing  securities  having  similar
maturity and credit quality.

U.S. TREASURY STRIPS

         The Prime Money Market Fund, Prime Value Money Market Fund,  Government
Obligations Money Market Fund and Treasury  Instruments Money Market Fund II may
invest in  separately  traded  principal  and interest  components of securities
backed by the full  faith and credit of the U.S.  Treasury.  The  principal  and
interest  components of U.S. Treasury bonds with remaining  maturities of longer
than ten  years  are  eligible  to be traded  independently  under the  Separate
Trading of Registered  Interest and Principal of Securities  ("STRIPS") program.
Under the STRIPS program,  the principal and interest  components are separately
issued by the U.S. Treasury at the request of depository financial institutions,
which then trade the component parts  separately.  Under the stripped bond rules
of the Internal  Revenue Code of 1986, as amended (the "Code"),  investments  by
the Funds in  STRIPS  will  result in the  accrual  of  interest  income on such
investments in advance of the receipt of the cash  corresponding to such income.
The interest component of STRIPS may be more volatile than that of U.S. Treasury
bills with  comparable  maturities.  In  accordance  with Rule 2a-7,  the Funds'
investments  in  STRIPS  are  limited  to those  with  maturity  components  not
exceeding thirteen months.

                                       12

LENDING OF PORTFOLIO SECURITIES

         Each Fund may lend portfolio securities up to one-third of the value of
its  total   assets  to  U.S.  and  foreign   broker/dealers,   banks  or  other
institutional  borrowers  of  securities  that the  Adviser has  determined  are
creditworthy  under guidelines  established by the Board of Trustees.  The Funds
will receive collateral in the form of cash, letters of credit, or securities of
the U.S.  government or its agencies  equal to at least 100% of the value of the
securities owned.

VARIABLE AND FLOATING RATE SECURITIES

         The interest  rates payable on certain  securities in which Prime Money
Market Fund, Prime Value Money Market Fund, Government  Obligations Money Market
Fund,  Tax-Free Money Market Fund and Municipal Money Market Fund may invest are
not fixed and may fluctuate  based upon changes in market rates. A variable rate
obligation  has an interest  rate which is adjusted  at  predesignated  periods.
Interest on a floating rate obligation is adjusted whenever there is a change in
the  market  rate of  interest  on which the  interest  rate  payable  is based.
Tax-exempt variable or floating rate obligations generally permit the holders of
such obligations to demand payment of principal from the issuer or a third party
at stated  intervals.  Variable and floating rate obligations are less effective
than fixed rate instruments at locking in a particular  yield.  Such obligations
may  fluctuate in value in response to interest rate changes if there is a delay
between  changes in market  interest  rates and the interest  reset date for the
obligation.  The Funds will take demand or reset features into  consideration in
determining  the  average  portfolio  duration  of the  Fund  and the  effective
maturity of individual securities.  In addition, the absence of an unconditional
demand feature  exercisable within seven days will require a tax-exempt variable
or floating  rate  obligation to be treated as illiquid for purposes of a Fund's
limitation on illiquid  investments.  The failure of the issuer or a third party
to honor its  obligations  under a demand or put  feature  might also  require a
tax-exempt  variable or floating  rate  obligation to be treated as illiquid for
purposes of a Fund's limitation on illiquid investments.

TAX-EXEMPT COMMERCIAL PAPER

         Tax-Free  Money Market Fund and Municipal  Money Market Fund may invest
in tax-exempt  commercial paper.  Issues of commercial paper typically represent
short-term, unsecured, negotiable promissory notes. These obligations are issued
by state and local  governments  and their agencies to finance  working  capital
needs of  municipalities  or to provide interim  construction  financing and are
paid from general or specific revenues of municipalities or are re-financed with
long-term debt. In some cases,  tax-exempt commercial paper is backed by letters
of credit,  lending  agreements,  note  repurchase  agreements  or other  credit
facility  arrangements  offered by banks or other  institutions.  The Funds will
invest only in tax-exempt  commercial paper rated at least Prime-2 by Moody's or
A-2 by S&P.

MUNICIPAL OBLIGATIONS

         Tax-Free  Money Market Fund and Municipal  Money Market Fund may invest
in the Municipal Obligations described below.

         Municipal  Obligations.  Municipal Obligations include bonds, notes and
other instruments issued by or on behalf of states,  territories and possessions
of the United States  (including  the District of Columbia) and their  political
subdivisions,  agencies or  instrumentalities,  the interest on which is, in the
opinion of bond counsel,  exempt from regular federal income tax (i.e., excluded
from gross income for federal  income tax purposes  but not  necessarily  exempt
from the personal  income  taxes of any state or, with respect to the  Municipal
Money Market  Fund,  from the federal  alternative  minimum  tax).  In addition,
Municipal  Obligations  include  participation  interests in such securities the
interest on which is, in the opinion of bond  counsel for the issuers or counsel
selected by the Adviser,  exempt from regular federal income tax. The definition
of Municipal Obligations includes other types of securities that currently exist
or may be  developed  in the future and that are,  or will be, in the opinion of
counsel,  as described above,  exempt from regular federal income tax,  provided
that  investing  in such  securities  is  consistent  with a  Fund's  investment
objective and policies.

                                       13


<PAGE>


         The two principal classifications of Municipal Obligations which may be
held by the Funds are "general obligation"  securities and "revenue" securities.
General  obligation  securities  are secured by the issuer's  pledge of its full
faith,  credit  and taxing  power for the  payment of  principal  and  interest.
Revenue  securities are payable only from the revenues derived from a particular
facility  or class of  facilities,  or in some  cases,  from the  proceeds  of a
special  excise tax or other  specific  revenue  source  such as the user of the
facility being financed. Revenue securities include private activity bonds which
may be held by the  Municipal  Money  Market Fund and which are not payable from
the unrestricted  revenues of the issuer.  While some private activity bonds are
general  obligation  securities,  the  vast  majority  are  revenue  securities.
Consequently,  the credit quality of private  activity bonds is usually directly
related to the credit  standing of the corporate user of the facility  involved.
Each of the Municipal  Obligations  described  below may take the form of either
general obligation or revenue securities.

         Municipal  Obligations  are often  issued to obtain  funds for  various
public purposes, including the construction of a wide range of public facilities
such as bridges,  highways,  housing,  hospitals, mass transportation,  schools,
streets and water and sewer  works.  Other public  purposes for which  Municipal
Obligations may be issued include refunding outstanding  obligations,  obtaining
funds for  general  operating  expenses,  and  obtaining  funds to lend to other
public   institutions  and  facilities.   Municipal   Obligations  also  include
industrial  development  bonds or, with  respect to the  Municipal  Money Market
Fund,  private  activity  bonds,  which  are  issued  by or on  behalf of public
authorities to obtain funds for privately-operated housing facilities,  airport,
mass  transit or port  facilities,  sewage  disposal,  solid  waste  disposal or
hazardous  waste treatment or disposal  facilities and certain local  facilities
for  water  supply,  gas  or  electricity.  In  addition,  proceeds  of  certain
industrial development bonds are used for the construction, equipment, repair or
improvement  of privately  operated  industrial  or commercial  facilities.  The
interest income from private activity bonds may subject certain investors to the
federal alternative minimum tax.

         Municipal Leases, Certificates of Participation and Other Participation
Interests.  The Funds  may  invest  in  municipal  leases  and  certificates  of
participation  in municipal  leases.  A municipal  lease is an obligation in the
form of a lease or  installment  purchase  which is  issued  by a state or local
government to acquire equipment and facilities.  Income from such obligations is
generally exempt from state and local taxes in the state of issuance.  Municipal
leases  frequently  involve  special risks not normally  associated with general
obligation or revenue bonds. Leases and installment purchase or conditional sale
contracts  (which  normally  provide  for  title  to the  leased  asset  to pass
eventually to the governmental  issuer) have evolved as a means for governmental
issuers to acquire property and equipment without meeting the constitutional and
statutory  requirements for the issuance of debt. The debt issuance  limitations
are  deemed  to be  inapplicable  because  of the  inclusion  in many  leases or
contracts of "non-appropriation" clauses that relieve the governmental issuer of
any obligation to make future  payments under the lease or contract unless money
is appropriated for such purpose by the appropriate legislative body on a yearly
or other periodic basis. In addition, such leases or contracts may be subject to
the  temporary  abatement of payments in the event the issuer is prevented  from
maintaining  occupancy of the leased premises or utilizing the leased equipment.
Although the  obligation  may be secured by the leased  equipment or facilities,
the disposition of the property in the event of  nonappropriation or foreclosure
might  prove   difficult,   time   consuming  and  costly,   and  result  in  an
unsatisfactory or delayed recoupment of the Fund's original investment.

         Certificates  of  participation   represent   undivided   interests  in
municipal leases,  installment  purchase  agreements or other  instruments.  The
certificates  are typically issued by a trust or other entity which has received
an assignment  of the payments to be made by the state or political  subdivision
under such leases or installment purchase agreements.

         Certain  municipal lease  obligations and certificates of participation
may be deemed illiquid for the purpose of a Fund's  limitation on investments in
illiquid  securities.  Other  municipal lease  obligations  and  certificates of
participation  acquired by the Funds may be determined by the Adviser,  pursuant
to guidelines adopted by the Board of Trustees,  to be liquid securities for the
purpose of such  limitation.  In  determining  the liquidity of municipal  lease
obligations  and  certificates  of  participation,  the Adviser will  consider a
variety  of  factors  including  (a) the  willingness  of dealers to bid for the
security,  (b) the number of dealers  willing to purchase or sell the obligation
and the number of other potential buyers, (c) the

                                       14


<PAGE>


frequency  of  trades  or  quotes  for the  obligation,  and (d) the  nature  of
marketplace  trades.  In addition,  the Adviser will consider  factors unique to
particular lease  obligations and  certificates of  participation  affecting the
marketability thereof. These include the general creditworthiness of the issuer,
the  importance  of the  property  covered  by the lease to the  issuer  and the
likelihood  that  the   marketability  of  the  obligation  will  be  maintained
throughout the time the obligation is held by the Funds.

         The Funds may also  purchase  participations  in Municipal  Obligations
held by a commercial bank or other financial  institution.  Such  participations
provide  the  Funds  with  the  right to a pro rata  undivided  interest  in the
underlying Municipal  Obligations.  In addition,  such participations  generally
provide the Funds with the right to demand payment,  on not more than seven days
notice, of all or any part of a Fund's participation  interest in the underlying
Municipal Obligation, plus accrued interest. These demand features will be taken
into consideration in determining the effective maturity of such  participations
and the average  portfolio  duration of the Funds. The Funds will only invest in
such  participations  if, in the  opinion  of bond  counsel  for the  issuers or
counsel selected by the Adviser, the interest from such participations is exempt
from regular federal income tax.

         Municipal  Notes.  Municipal  Obligations  purchased  by the  Funds may
include  fixed-rate notes or variable-rate  demand notes.  Such notes may not be
rated by credit rating  agencies,  but unrated notes purchased by the Funds will
be determined by the Adviser to be of comparable quality at the time of purchase
to rated instruments purchasable by the Funds. Where necessary to determine that
a note is an Eligible Security or First Tier Eligible  Security,  the Funds will
require the issuer's obligation to pay the principal of the note be backed by an
unconditional  bank letter or line of credit,  guarantee or  commitment to lend.
While  there may be no active  secondary  market  with  respect to a  particular
variable  rate demand note  purchased by the Funds,  the Funds may,  upon notice
specified in the note,  demand  payment of the principal of the note at any time
or during specified  periods not exceeding  thirteen months,  depending upon the
instrument  involved,  and may resell the note at any time to a third party. The
absence of such an active secondary market, however, could make it difficult for
the Funds to dispose  of a  variable  rate  demand  note if the  issuer  were to
default  on its  payment  obligation  or during  periods  that the Funds are not
entitled to exercise their demand rights, and the Funds could, for this or other
reasons, suffer losses to the extent of the default.

         Pre-Refunded   Municipal   Obligations.   The  Funds   may   invest  in
pre-refunded   Municipal   Obligations.   The   principal  of  and  interest  on
pre-refunded  Municipal Obligations are no longer paid from the original revenue
source for the Municipal  Obligations.  Instead,  the source of such payments is
typically an escrow fund  consisting of obligations  issued or guaranteed by the
U.S. Government.  The assets in the escrow fund are derived from the proceeds of
refunding  bonds  issued  by  the  same  issuer  as the  pre-refunded  Municipal
Obligations,  but  usually on terms more  favorable  to the  issuer.  Issuers of
Municipal  Obligations  use this  advance  refunding  technique  to obtain  more
favorable terms with respect to Municipal  Obligations which are not yet subject
to call or redemption by the issuer.  For example,  advance refunding enables an
issuer to refinance debt at lower market  interest  rates,  restructure  debt to
improve cash flow or eliminate  restrictive  covenants in the indenture or other
governing instrument for the pre-refunded Municipal Obligations. However, except
for a change in the revenue  source from which  principal and interest  payments
are made, the pre-refunded  Municipal  Obligations  remain  outstanding on their
original  terms until they mature or are redeemed by the issuer.  The  effective
maturity of pre-refunded  Municipal  Obligations  will be the redemption date if
the issuer has assumed an  obligation  or indicated its intention to redeem such
obligations on the redemption date. Pre-refunded Municipal Obligations are often
purchased at a price which represents a premium over their face value.

         Tender Option  Bonds.  The Funds may purchase  tender  option bonds.  A
tender  option  bond is a Municipal  Obligation  (generally  held  pursuant to a
custodial arrangement) having a relatively long maturity and bearing interest at
a fixed rate substantially higher than prevailing  short-term  tax-exempt rates,
that has been  coupled  with the  agreement  of a third  party,  such as a bank,
broker-dealer or other financial institution, pursuant to which such institution
grants the security holders the option, at periodic  intervals,  to tender their
securities  to  the  institution   and  receive  the  face  value  thereof.   As
consideration  for providing  the option,  the  financial  institution  receives
periodic fees equal to the difference between the Municipal

                                       15


<PAGE>


Obligation's  fixed coupon rate and the rate, as determined by a remarketing  or
similar agent at or near the  commencement of such period,  that would cause the
securities,  coupled with the tender option, to trade at or near par on the date
of such  determination.  Thus,  after  payment of this fee, the security  holder
effectively  holds a demand  obligation  that bears  interest at the  prevailing
short-term  tax-exempt  rate.  The Adviser will consider on an ongoing basis the
creditworthiness of the issuer of the underlying  Municipal  Obligation,  of any
custodian  and of the third  party  provider  of the tender  option.  In certain
instances and for certain  tender option bonds,  the option may be terminable in
the event of a default in payment of  principal  or interest  on the  underlying
Municipal Obligations and for other reasons. Additionally, the above description
of tender  option  bonds is meant only to  provide  an  example of one  possible
structure of such  obligations,  and the Funds may purchase  tender option bonds
with   different   types  of  ownership,   payment,   credit  and/or   liquidity
arrangements.

                             INVESTMENT LIMITATIONS

         The Funds' investment  objectives and policies  described above are not
fundamental  and may be  changed  by the  Board of  Trustees  without  a vote of
shareholders.  If there  is a  change  in the  investment  objective  of a Fund,
shareholders should consider whether the Fund remains an appropriate  investment
in light of  their  then  current  financial  position  and  needs.  The  Funds'
investment   limitations   described  below  may  not  be  changed  without  the
affirmative vote of the holders of a majority of its outstanding  shares.  There
can be no assurance that the Funds will achieve their investment objectives.  (A
complete list of the  investment  limitations  that cannot be changed  without a
vote of  shareholders  is contained in the Statement of  Additional  Information
under "Investment Objectives and Policies.")

         The Funds may not:

         1. Borrow money,  except that a Fund may (i) borrow money for temporary
or emergency  purposes (not for leveraging or investment) from banks, or subject
to specific  authorization  by the SEC,  from funds advised by the Adviser or an
affiliate  of the  Adviser,  and (ii) engage in reverse  repurchase  agreements;
provided that (i) and (ii) in combination  do not exceed  one-third of the value
of the Fund's total assets  (including  the amount  borrowed)  less  liabilities
(other than borrowings).  The Funds may not mortgage,  pledge or hypothecate any
assets  except  in  connection  with  such  borrowings  and  reverse  repurchase
agreements and then only in amounts not exceeding  one-third of the value of the
particular  Fund's  total  assets  at the  time  of such  borrowing.  Additional
investments  will not be made by the  Funds  when  borrowings  exceed  5% of the
Fund's assets.

         2. Purchase any  securities  which would cause 25% or more of the value
of its total assets at the time such  purchase to be invested in the  securities
of one of more issuers  conducting  their principal  business  activities in the
same industry, except that Prime Value Money Market Fund will invest 25% or more
of the value of its total  assets  in  obligations  of  issuers  in the  banking
industry  or in  obligations,  such as  repurchase  agreements,  secured by such
obligations  (unless the Fund is in a temporary  defensive  position);  provided
that there is no  limitation  with  respect to  investments  in U.S.  Government
securities  or, in the case of Prime  Money  Market  Fund,  in bank  instruments
issued by domestic banks.

         3.  Make  loans  except  that a Fund  may (i)  purchase  or  hold  debt
obligations in accordance with its investment objective and policies, (ii) enter
into repurchase  agreements for securities,  (iii) lend portfolio securities and
(iv) with the exception of Government  Obligations Money Market Fund, subject to
specific  authorization  by the SEC,  lend money to other  funds  advised by the
Adviser or an affiliate of the Adviser.

         Each Fund may, in the future, seek to achieve its investment  objective
by  investing  all of its assets in a no-load,  open-end  management  investment
company having the same investment  objective and policies and substantially the
same  investment  restrictions  as those  applicable to the Fund. In such event,
each Fund's investment  advisory agreement would be terminated.  Such investment
would be made only if the Trust's Board of Trustees  believes that the aggregate
per share expenses of each class of the Fund and such

                                       16


<PAGE>


other  investment  company  will be  less  than or  approximately  equal  to the
expenses  which each class of the Fund would  incur if the Fund were to continue
to retain the services of an  investment  adviser for the Fund and the assets of
the Fund were to continue to be invested directly in portfolio securities.

                        PURCHASE AND REDEMPTION OF SHARES

         To allow the  Adviser to manage the Funds  effectively,  investors  are
strongly  urged to initiate all  investments  or  redemptions  of Fund shares as
early in the day as possible and to notify  Lehman  Brothers at least one day in
advance of transactions in excess of $5 million.

PURCHASE PROCEDURES

         Shares of the  Funds  are sold at the net asset  value per share of the
Fund next determined after receipt of a purchase order by Lehman  Brothers,  the
Distributor of the Fund's shares.  Purchase  orders for shares are accepted only
on days on which both the New York Stock  Exchange and the Federal  Reserve Bank
of Boston are open for business and must be transmitted to Lehman  Brothers,  by

         Payment for Fund shares may be made only in federal  funds  immediately
available to Boston Safe Deposit and Trust Company ("Boston Safe").  Payment for
orders  which are not received or accepted by Lehman  Brothers  will be returned
after prompt  inquiry to the sending  institution.  A Fund may in its discretion
reject any order for shares.  Any person  entitled to receive  compensation  for
selling or servicing shares of the Funds may receive different  compensation for
selling or servicing one Class of shares over another Class.

         The minimum aggregate initial investment by an institution in the Funds
is $1 million  (with not less than $25,000  invested in any one Fund);  however,
broker-dealers  and other  institutional  investors may set a higher minimum for
their customers.  To reach the minimum Trust-wide initial investment,  purchases
of shares may be  aggregated  over a period of six  months.  There is no minimum
subsequent investment.

         Conflicts  of  interest  restrictions  may  apply  to an  institution's
receipt of  compensation  paid by the Funds on fiduciary funds that are invested
in Class B Shares. See also "Management of the Funds -- Service  Organizations."
Institutions,  including  banks regulated by the Comptroller of the Currency and
investment  advisers and other money managers subject to the jurisdiction of the
SEC,  the  Department  of Labor or state  securities  commissions,  are urged to
consult their legal advisers before investing fiduciary funds in Class B Shares.

</TABLE>

- ----------
* All times stated are Eastern time.

         Shares are  redeemed at the net asset  value per share next  determined
after Lehman Brothers' receipt of the redemption  order.  While the Funds intend
to use their best efforts to maintain  their net asset value per share at $1.00,
the proceeds  paid to an investor upon  redemption  may be more or less than the
amount  invested  depending  upon a  share's  net  asset  value  at the  time of
redemption.

         The Funds reserve the right to wire  redemption  proceeds  within seven
days after receiving the redemption order if, in the judgment of the Adviser, an
earlier payment could adversely affect the Funds. The Funds shall have the right
to redeem  involuntarily  shares in any  account at their net asset value if the
value of the account is less than $10,000 after 60 days' prior written notice to
the investor.  Any such redemption  shall be effected at the net asset value per
share next  determined  after the  redemption  order is  entered.  If during the
60-day  period the  investor  increases  the value of its  account to $10,000 or
more, no such  redemption  shall take place.  In addition,  the Funds may redeem
shares  involuntarily  or suspend the right of redemption as permitted under the
Investment  Company Act of 1940,  as amended (the "1940 Act"),  or under certain
special circumstances described in the Statement of Additional Information under
"Additional Purchase and Redemption Information."

         The ability to give  telephone  instructions  for the  redemption  (and
purchase or exchange) of shares is  automatically  established  on an investor's
account.  However,  the Funds  reserve  the right to refuse a  redemption  order
transmitted  by telephone if it is believed  advisable to do so.  Procedures for
redeeming  Fund shares by telephone may be modified or terminated at any time by
the Funds or Lehman Brothers.  In addition,  neither the Funds,  Lehman Brothers
nor First Data Investor Services Group,  Inc.  ("FDISG") will be responsible for
the  authenticity  of telephone  instructions  for the  purchase,  redemption or
exchange of shares where the instructions are reasonably believed to be genuine.
Accordingly,  the investor will bear the risk of loss. The Funds will attempt to
confirm that telephone  instructions are genuine and will use such procedures as
are considered reasonable, including the recording of telephone instructions. To
the  extent  that the Funds  fail to use  reasonable  procedures  to verify  the
genuineness of telephone instructions,  the Funds or their service providers may
be liable for such instructions that prove to be fraudulent or unauthorized.

EXCHANGE PROCEDURES

         The Exchange Privilege enables an investor to exchange shares of a Fund
without  charge for shares of the same class of other Funds which have different
investment objectives that may be of interest to investors.  To use the Exchange
Privilege,  exchange  instructions must be given to Lehman Brothers by telephone
or through LEX. See "Redemption  Procedures." In exchanging  shares, an investor
must meet the minimum initial  investment  requirement of the other Fund and the
shares involved must be legally

                                       18


<PAGE>


available for sale in the state where the investor resides. Before any exchange,
the investor must also obtain and should review a copy of the current prospectus
of the Funds.  Prospectuses  may be  obtained  from  Lehman  Brothers by calling
1-800-368-5556.  Shares will be exchanged at the net asset value next determined
after receipt of an exchange  request in proper form.  The exchange of shares of
one Fund for shares of another  Fund is treated for federal  income tax purposes
as a sale of the shares given in exchange by the  investor  and,  therefore,  an
investor  may  realize a taxable  gain or loss.  The Funds  reserve the right to
reject any exchange  request in whole or in part. The Exchange  Privilege may be
modified or terminated at any time upon notice to investors.

VALUATION OF SHARES-NET ASSET VALUE

         Each Fund's net asset value per share for purposes of pricing  purchase
and redemption orders is determined by the Fund's Administrator on each weekday,
with the exception of those holidays on which either the New York Stock Exchange
or the Federal  Reserve  Bank of Boston is closed,  according  to the  following
schedule.

- ----------
* All times stated are Eastern time.

         Currently,  one or both of the New York Stock  Exchange and the Federal
Reserve Bank of Boston are closed on the customary national business holidays of
New Year's Day, Martin Luther King, Jr.'s Birthday  (observed),  Presidents' Day
(Washington's Birthday), Good Friday, Memorial Day, Independence Day, Labor Day,
Columbus Day (observed),  Veterans Day,  Thanksgiving Day and Christmas Day, and
on the preceding Friday or subsequent Monday when one of these holidays falls on
a Saturday or Sunday, respectively. The net asset value per share of Fund shares
is calculated  separately  for each class by adding the value of all  securities
and other  assets  of the  Fund,  subtracting  class-specific  liabilities,  and
dividing the result by the total  number of the Fund's  outstanding  shares.  In
computing net asset value, each Fund uses the amortized cost method of valuation
as  described in the  Statement  of  Additional  Information  under  "Additional
Purchase  and  Redemption  Information."  A Fund's net asset value per share for
purposes of pricing purchase and redemption  orders is determined  independently
of the net asset values of the shares of each other Fund.

OTHER MATTERS

         Fund  shares  are  sold  and  redeemed  without  charge  by the  Funds.
Institutional  investors  purchasing  or holding Fund shares for their  customer
accounts  may  charge  customers  fees for cash  management  and other  services
provided  in  connection  with their  accounts.  A customer  should,  therefore,
consider the terms of its account with an  institution  before  purchasing  Fund
shares.  An  institution  purchasing  or redeeming  Fund shares on behalf of its
customers  is  responsible  for  transmitting   orders  to  Lehman  Brothers  in
accordance with its customer agreements.

                                    DIVIDENDS

         Investors of a Fund are entitled to dividends and distributions arising
only  from the net  investment  income  and  capital  gains,  if any,  earned on
investments  held by that Fund.  Each Fund's net  investment  income is declared
daily as a dividend  to shares  held of record at the close of  business  on the
date of  declaration.  Shares begin  accruing  dividends on the day the purchase
order for the shares is effective and continue to accrue  dividends  through the
day before such shares are redeemed. Dividends are paid monthly by wire transfer
within five  business  days after the end of the month or within  five  business
days after a redemption  of all of an investor's  shares of a particular  class.
The Funds do not expect to realize net long-term capital gains.

         Dividends  are  determined  in the same manner and are paid in the same
amount  for each Fund  share,  except  that  shares of each  class  bear all the
expenses associated with that specific class.

         Institutional investors may elect to have their dividends reinvested in
additional  full and fractional  shares of the same class of shares with respect
to which such  dividends  are  declared at the net asset value of such shares on
the  payment  date.  Reinvested  dividends  receive  the same tax  treatment  as
dividends paid in cash. Such election,  or any revocation thereof,  must be made
in  writing  to Lehman  Brothers,  260  Franklin  Street,  15th  Floor,  Boston,
Massachusetts 02110-9624,  and will become effective after its receipt by Lehman
Brothers, with respect to dividends paid.

         FDISG,  as Transfer  Agent,  will send each investor or its  authorized
representative  an annual statement  designating the amount of any dividends and
capital gains distributions, if any, made during each year and their federal tax
qualification.

                                      TAXES

         Each Fund  qualified in its last taxable year and intends to qualify in
future years as a  "regulated  investment  company"  under the Code. A regulated
investment  company is exempt from federal income tax on amounts  distributed to
its investors.

         Qualification  as a regulated  investment  company under the Code for a
taxable  year  requires,  among  other  things,  that a Fund  distribute  to its
investors at least 90% of its investment  company  taxable income for such year.
In  general,  a Fund's  investment  company  taxable  income will be its taxable
income  (including  dividends and short-term  capital gains,  if any) subject to
certain  adjustments and excluding the excess of any net long-term capital gains
for the taxable  year over the net  short-term  capital  loss,  if any, for such
year.  Each Fund  intends  to  distribute  substantially  all of its  investment
company taxable income each year. Such distributions will be taxable as ordinary
income to Fund investors who are not currently exempt from federal income taxes,
whether such income is received in cash or reinvested in additional  shares.  It
is  anticipated  that none of a Fund's  distributions  will be eligible  for the
dividends  received  deduction  for  corporations.  The  Funds do not  expect to
realize long-term capital gains and,  therefore,  do not contemplate  payment of
any "capital gain dividends" as described in the Code.

         Dividends  derived  from  exempt-interest  income from  Tax-Free  Money
Market  Fund and  Municipal  Money  Market  Fund may be  treated  by the  Fund's
investors as items of interest  excludable from their gross income under Section
103(a) of the Code, unless under the circumstances  applicable to the particular
investor the exclusion would be disallowed.

         Municipal  Money Market Fund may hold  without  limit  certain  private
activity bonds issued after August 7, 1986.  Investors must include,  as an item
of  tax  preference,  the  portion  of  dividends  paid  by  the  Fund  that  is
attributable to interest on such bonds in determining liability (if any) for the
federal  alternative  minimum tax.  Noncorporate  taxpayers,  depending on their
individual tax status,  may be subject to  alternative  minimum tax at a blended
rate between 26% and 28%. Corporate  taxpayers may be subject to (1) alternative
minimum tax at a rate of 20% of the excess of their alternative  minimum taxable
income  ("AMTI")  over the  exemption  amount,  and (2) the  environmental  tax.
Corporate investors must also take all

                                       20


<PAGE>


exempt-interest  dividends into account in determining  certain  adjustments for
federal  alternative  minimum and environmental tax purposes.  The environmental
tax applicable to  corporations  is imposed at the rate of .12% on the excess of
the  corporation's  modified  federal  alternative  minimum  taxable income over
$2,000,000.

         To the extent,  if any,  dividends  paid to investors by Tax-Free Money
Market Fund or Municipal  Money  Market Fund are derived from taxable  income or
from long-term or short-term  capital  gains,  such dividends will not be exempt
from federal income tax,  whether such dividends are paid in the form of cash or
additional shares, and may also be subject to state and local taxes.

         In addition  to federal  taxes,  an  investor  may be subject to state,
local or foreign  taxes on payments  received from a Fund. A state tax exemption
may be  available  in some  states to the extent  distributions  of the Fund are
derived from  interest on certain U.S.  Government  securities  or on securities
issued by public  authorities  in the state.  The Funds will  provide  investors
annually with information about federal income tax consequences of distributions
made each year.  Investors should be aware of the application of their state and
local tax laws to investments in the Funds.

         Investors  will be advised at least  annually as to the federal  income
tax status of distributions made to them each year.

         The  foregoing  discussion  is  only a  brief  summary  of  some of the
important  federal  tax  considerations  generally  affecting  a  Fund  and  its
shareholders.  No  attempt  is made to  present a  detailed  explanation  of the
federal,  state or local income tax  treatment of a Fund or its  investors,  and
this  discussion  is not  intended as a  substitute  for  careful tax  planning.
Accordingly,  potential investors in the Funds should consult their tax advisers
with  specific  reference  to their  own tax  situation.  See the  Statement  of
Additional Information for a further discussion of tax consequences of investing
in shares of the Funds.

                             MANAGEMENT OF THE FUNDS

         The business and affairs of the Funds are managed  under the  direction
of  the  Trust's  Board  of  Trustees.  The  Trustees  approve  all  significant
agreements  between the Trust and the persons or companies that furnish services
to the Funds, including agreements with its Distributor, Adviser, Administrator,
and Transfer  Agent and Custodian.  The  day-to-day  operations of the Funds are
delegated to the Funds' Adviser and  Administrator.  The Statement of Additional
Information contains general background  information  regarding each Trustee and
executive officer of the Trust.

DISTRIBUTOR

         Lehman  Brothers,  located at 3 World Financial  Center,  New York, New

the Trust pursuant to which it has the responsibility for distributing shares of
the Funds.

INVESTMENT ADVISER -- LEHMAN BROTHERS GLOBAL ASSET MANAGEMENT INC.

         LBGAM,  located at 3 World Financial Center,  New York, New York 10285,

affiliates,  serves as investment  adviser to  investment  companies and private
accounts  and has assets under  management  of  approximately  $11 billion as of

         As  Adviser  to the Funds,  LBGAM  manages  each  Fund's  portfolio  in
accordance  with  its  investment  objective  and  policies,   makes  investment
decisions  for the Funds,  places  orders to purchase  and sell  securities  and
employs  professional  portfolio  managers and  securities  analysts who provide
research  services to the Funds. For its services LBGAM is entitled to receive a
monthly fee from each Fund at the annual rate of .20% of the value of the Fund's
average daily net assets.

ADMINISTRATOR AND TRANSFER AGENT -- FIRST DATA INVESTOR SERVICES GROUP, INC.

         FDISG (formerly named The Shareholder Services Group, Inc.), located at
One Exchange Place, 53 State Street, Boston, Massachusetts 02109, serves as each
Fund's  Administrator and Transfer Agent. FDISG is a wholly-owned  subsidiary of
First Data Corporation.  As Administrator,  FDISG calculates the net asset value
of each  Fund's  shares  and  generally  assists in all  aspects of each  Fund's
administration   and  operation.   As  compensation   for  FDISG's  services  as
Administrator,  FDISG is entitled to receive from each Fund a monthly fee at the
annual rate of .10% of the value of the Fund's  average daily net assets.  FDISG
is also  entitled  to receive a fee from the Funds for its  services as Transfer
Agent.  FDISG pays Boston Safe, each Fund's Custodian,  a portion of its monthly
administration fee for custody services rendered to the Funds.

         On  May  6,  1994,   FDISG   acquired   the  third  party  mutual  fund
administration  business of The Boston  Company  Advisors,  Inc.,  an  indirect,
wholly-owned  subsidiary of Mellon Bank  Corporation  ("Mellon").  In connection
with the  transaction,  Mellon  assigned  to FDISG  its  agreement  with  Lehman
Brothers (then named Shearson Lehman Brothers Inc.) that Lehman Brothers and its
affiliates,  consistent with their fiduciary duties and assuming certain service
quality   standards  are  met,  would   recommend   FDISG  as  the  provider  of
administration  services to the Funds. This duty to recommend expires on May 21,
2000.

Place, Boston,  Massachusetts 02108, serves as each Fund's Custodian.  Under the
terms of the Stock Purchase  Agreement  dated  September 14, 1992 between Mellon
and Lehman Brothers (then named Shearson Lehman Brothers Inc.),  Lehman Brothers
agreed to recommend  Boston Safe as Custodian  of mutual funds  affiliated  with
Lehman  Brothers until May 21, 2000 to the extent  consistent with its fiduciary
duties and other applicable law.

SERVICE ORGANIZATIONS

         Under a Plan of  Distribution  (the  "Plan")  adopted  pursuant to Rule
12b-1 under the 1940 Act,  Class B Shares bear fees ("Rule 12b-1 fees")  payable
by the Funds at the aggregate rate of up to .25% (on an annualized basis) of the
average  daily net asset value of such shares to Lehman  Brothers for  providing
certain services to the Funds and holders of Class B Shares. Lehman Brothers may
retain all the payments  made to it under the Plan or may enter into  agreements
with and make payments of up to .25% to  institutional  investors such as banks,
savings  and  loan  associations  and  other  financial  institutions  ("Service
Organizations") for the provision of a portion of such services. These services,
which are described more fully in the Statement of Additional  Information under
"Management  of the Funds -- Service  Organizations,"  include  aggregating  and
processing  purchase and redemption  requests from  shareholders and placing net
purchase  and  redemption  orders  with  Lehman  Brothers;  processing  dividend
payments  from the  Funds  on  behalf  of  shareholders;  providing  information
periodically  to shareholders  showing their positions in shares;  arranging for
bank  wires;  responding  to  shareholder  inquiries  relating  to the  services

allows Lehman Brothers to use its own resources to provide distribution services
and  shareholder  services.  Under  the  terms of  related  agreements,  Service
Organizations  are required to provide to their  shareholders  a schedule of any
fees that they may charge  shareholders in connection with their  investments in
Class B Shares.

EXPENSES

         Each Fund bears all its own expenses.  A Fund's expenses include taxes,
interest,  fees and  salaries of the Trust's  trustees  and officers who are not
directors,  officers or employees of the Fund's service  contractors,  SEC fees,
state   securities   qualification   fees,   costs  of  preparing  and  printing
prospectuses  for  regulatory   purposes  and  for  distribution  to  investors,
advisory,  administration  and  distribution  fees,  charges  of the  custodian,
administrator,   transfer   agent  and  dividend   disbursing   agent,   Service
Organization  fees,  certain  insurance  premiums,  outside  auditing  and legal
expenses,  costs  of  shareholder  reports  and  shareholder  meetings  and  any
extraordinary  expenses.  Each Fund also pays for brokerage fees and commissions
(if any) in connection  with the purchase and sale of portfolio  securities.  In
order to maintain a competitive  expense  ratio,  the Adviser and  Administrator
have  voluntarily  agreed to waive  fees and  reimburse  expenses  to the extent
necessary  to maintain an  annualized  expense  ratio at a level no greater than
 .43% of average daily net assets (.18%  excluding  Rule 12b-1 fees) with respect
to the Funds.  This voluntary waiver and  reimbursement  arrangement will not be
changed  unless  investors  are provided at least 60 days'  advance  notice.  In
addition,  these  service  providers  have agreed to reimburse  the Funds to the
extent required by applicable  state law for certain expenses that are described
in the  Statement  of  Additional  Information.  Any  fees  charged  by  Service
Organizations or other institutional  investors to their customers in connection
with investments in Fund shares are not reflected in a Fund's expenses.

                             PERFORMANCE AND YIELDS

         From time to time, the "yields" and "effective  yields" with respect to
all Funds,  and  "tax-equivalent  yields" with respect to Municipal Money Market
Fund and  Tax-Free  Money  Market Fund,  may be quoted in  advertisements  or in
reports to shareholders. Yield quotations are computed separately for each class
of shares. The "yield" quoted in advertisements for a particular class of shares
refers to the income  generated by an investment in such shares over a specified
period (such as a seven-day period) identified in the advertisement. This income
is then  "annualized;" that is, the amount of income generated by the investment
during that period is assumed to be generated each such period over a 52-week or
one-year period and is shown as a percentage of the  investment.  The "effective
yield" is calculated  similarly  but, when  annualized,  the income earned by an
investment in a particular  class is assumed to be  reinvested.  The  "effective
yield" will be  slightly  higher  than the  "yield"  because of the  compounding
effect of this assumed reinvestment. The "tax-equivalent yield" demonstrates the
level of taxable yield necessary to produce an after-tax  yield  equivalent to a
Fund's  tax-free yield for each class of shares.  It is calculated by increasing
the yield  (calculated as above) by the amount  necessary to reflect the payment
of federal  taxes at a stated rate.  The  "tax-equivalent  yield" will always be
higher than the "yield."

         A Fund's  performance  may be compared to those of other  mutual  funds
with similar  objectives,  to other relevant indices, or to rankings prepared by
independent  services or other financial or industry  publications  that monitor
the performance of mutual funds. For example, such data are reported in national
financial publications such as Morningstar, Inc., Barron's, IBC/Donoghue's Money
Fund Report(,  The Wall Street Journal and The New York Times;  reports prepared
by Lipper  Analytical  Services,  Inc; and  publications  of a local or regional
nature.

         A  Fund's  yield  figures  for  a  class  of  shares   represent   past
performance,  will fluctuate and should not be considered as  representative  of
future results. The yield of any investment is generally a function of portfolio
quality and  maturity,  type of  investment  and  operating  expenses.  Any fees
charged by Service  Organizations or other  institutional  investors directly to
their customers in connection with  investments in Fund shares are not reflected
in a Fund's  expenses or yields;  and, such fees,  if charged,  would reduce the
actual return  received by customers on their  investments.  The methods used to
compute  a Fund's  yields  are  described  in more  detail in the  Statement  of
Additional  Information.  Investors may call  1-800-238-2560  to obtain  current
yield information.

                     DESCRIPTION OF SHARES AND MISCELLANEOUS

         The Trust is a Massachusetts business trust established on November 25,
1992. The Trust's Declaration of Trust authorizes the Board of Trustees to issue
an unlimited number of full and fractional shares of beneficial  interest in the
Trust  and to  classify  or  reclassify  any  unissued  shares  into one or more
additional  classes of shares.  The Trust is an open-end  management  investment
company,  which currently  offers ten  portfolios.  The Trust has authorized the
issuance  of seven  classes  of  shares  for  Prime  Value  Money  Market  Fund,
Government  Obligations  Money Market Fund and  Municipal  Money Market Fund and
four  classes of shares for Prime  Money  Market  Fund,  Cash  Management  Fund,
Treasury  Instruments  Money Market Fund II and Tax-Free  Money Market Fund. The
issuance  of separate  classes of shares is  intended  to address the  different
service needs of different types of investors.  The Declaration of Trust further
authorizes  the Trustees to classify or reclassify  any class of shares into one
or more sub-classes.

         The  Trust  does  not  presently  intend  to hold  annual  meetings  of
shareholders  except as required by the 1940 Act or other  applicable  law.  The
Trust will call a meeting of  shareholders  for the  purpose of voting  upon the
question of removal of a member of the Board of Trustees upon written request of
shareholders owning at least 10% of the outstanding shares of the Trust entitled
to vote.

         Each Fund share  represents  an equal,  proportionate  interest  in the
assets belonging to the Fund. Each share, which has a par value of $.001, has no
preemptive  or conversion  rights.  When issued for payment as described in this
Prospectus, Fund shares will be fully paid and non-assessable.

         Holders  of the Fund's  shares  will vote in the  aggregate  and not by
class on all matters, except where otherwise required by law and except when the
Board of Trustees  determines  that the matter to be voted upon affects only the
shareholders of a particular class. Further, shareholders of the Funds will vote
in the  aggregate  and not by portfolio  except as otherwise  required by law or
when the Board of Trustees  determines  that the matter to be voted upon affects
only the  interests  of the  shareholders  of a  particular  portfolio  (see the
Statement of Additional  Information  under "Additional  Description  Concerning
Fund Shares" for  examples  where the 1940 Act  requires  voting by  portfolio).
Shareholders  of the Trust are  entitled  to one vote for each full  share  held
(irrespective of class or portfolio) and fractional votes for fractional  shares
held. Voting rights are not cumulative;  and,  accordingly,  the holders of more
than 50% of the aggregate shares of the Trust may elect all of the trustees.

         For  information  concerning the redemption of Fund shares and possible
restrictions on their transferability, see "Purchase and Redemption of Shares."

                        SUMMARY OF INVESTMENT OBJECTIVES

         The  investment  objectives  of the Funds  are  summarized  below.  See
"Investment  Objectives  and  Policies"  beginning  on page 7 for more  detailed
information.

         PRIME MONEY MARKET FUND seeks to provide  current  income and stability
of principal by investing in a broad range of short-term instruments,  including
U.S.  Government  and  U.S.  bank  and  commercial  obligations  and  repurchase
agreements relating to such obligations.

         PRIME  VALUE  MONEY  MARKET  FUND seeks to provide  current  income and
stability of principal by investing in a portfolio  consisting  of a broad range
of  short-term  instruments,   including  U.S.  Government  and  U.S.  bank  and
commercial  obligations and repurchase  agreements relating to such obligations.
Under normal market conditions,  at least 25% of the Fund's total assets will be
invested  in  obligations  of issuers in the  banking  industry  and  repurchase
agreements relating to such obligations.

         GOVERNMENT  OBLIGATIONS  MONEY  MARKET  FUND seeks to  provide  current
income with  liquidity  and  security of  principal  by investing in a portfolio
consisting  of U.S.  Treasury  bills,  notes  and  other  obligations  issued or
guaranteed  by the  U.S.  Government,  its  agencies  or  instrumentalities  and
repurchase agreements relating to such obligations.

         TREASURY  INSTRUMENTS  MONEY  MARKET  FUND II seeks to provide  current
income with  liquidity  and  security of  principal  by investing in a portfolio
consisting of U.S.  Treasury  bills,  notes and direct  obligations  of the U.S.
Treasury and repurchase agreements relating to direct Treasury obligations.

         TAX-FREE  MONEY MARKET FUND seeks to provide as high a level of current
income exempt from federal taxation as is consistent with relative  stability of
principal  by  investing  in a portfolio  consisting  of  short-term  tax-exempt
obligations   issued  by  state  and  local  governments  and  other  tax-exempt
securities which are considered  "First Tier Eligible  Securities" as defined in
"Investment  Objectives and Policies." The Fund will not purchase securities the
income from which may be a specific tax preference  item for purposes of federal
individual and corporate alternative minimum tax.

         MUNICIPAL MONEY MARKET FUND seeks to provide as high a level of current
income exempt from federal taxation as is consistent with relative  stability of
principal  by  investing  in a portfolio  consisting  of  short-term  tax-exempt
obligations   issued  by  state  and  local  governments  and  other  tax-exempt
securities which are considered "Eligible  Securities" as defined in "Investment
Objectives and Policies."

         There is no  assurance  that the Funds will  achieve  their  respective
investment objectives.

                       BACKGROUND AND EXPENSE INFORMATION

         Each Fund currently  offers four classes of shares,  only one of which,
Class C Shares,  is offered by this Prospectus.  Each class represents an equal,
pro rata interest in a Fund.  Each Fund's other classes of shares have different
service  and/or  distribution  fees and expenses from Class C Shares which would
affect  the  performance  of those  classes  of  shares.  Investors  may  obtain
information  concerning  the Funds'  other  classes of shares by calling  Lehman
Brothers at 1-800-368-5556.

         The  purpose  of the  following  table  is to  assist  an  investor  in
understanding  the various  costs and  estimated  expenses that an investor in a
Fund would bear directly or  indirectly.  Certain  institutions  may also charge
their clients fees in connection with investments in Class C Shares,  which fees
are not  reflected in the table below.  For more  complete  descriptions  of the
various costs and expenses, see "Management of the Funds" in this Prospectus and
the Statement of Additional Information.

*   The Expense Summary above has been restated to reflect current expected fees
    and the  Adviser's  and  Administrator's  voluntary  fee waiver and  expense
    reimbursement arrangements currently in effect.

         In order to  maintain a  competitive  expense  ratio,  the  Adviser and
Administrator  have voluntarily  agreed to waive fees and reimburse  expenses to
the extent  necessary  to maintain  an  annualized  expense  ratio at a level no
greater than .53% of average daily net assets (.18%  excluding  Rule 12b-1 fees)
with respect

                                        4

to the Funds.  The voluntary fee waiver and expense  reimbursement  arrangements
described above will not be changed unless shareholders are provided at least 60
days' advance notice. The maximum annual contractual fees payable to the Adviser
and  Administrator  total .30% of average daily net assets of the Funds.  Absent

                       INVESTMENT OBJECTIVES AND POLICIES

         The  investment  objectives  and  general  policies  of each  Fund  are
described  below.  Specific  investment  techniques  that may be employed by the
Funds are described in a separate  section of this  Prospectus.  See  "Portfolio
Instruments  and  Practices."  Differences  in objectives and policies among the
Funds,  differences in the degree of acceptable risk and tax  considerations are
some of the factors that can be expected to affect the investment return of each
Fund. Because of such factors,  the performance  results of the Funds may differ
even though more than one Fund may utilize the same security selections.

         Unless  otherwise  stated,  the investment  objectives and policies set
forth in this  Prospectus are not fundamental and may be changed by the Board of
Trustees without  shareholder  approval.  If there is a change in the investment
objective and policies of any Fund,  shareholders  should  consider  whether the
Fund remains an appropriate  investment in light of their then-current financial
position and needs. The market value of certain  fixed-rate  obligations held by
the Funds will generally vary inversely with changes in market  interest  rates.
Thus,  the market value of these  obligations  generally  declines when interest
rates  rise and  generally  rises when  interest  rates  decline.  The Funds are
subject to  additional  investment  policies and  restrictions  described in the
Statement of Additional  Information,  some of which are fundamental and may not
be changed without shareholder approval.

         The  Funds  seek to  maintain  a net asset  value of $1.00  per  share,
although  there is no assurance  that they will be able to do so on a continuing
basis.  Each  Fund  operates  as a  diversified  investment  portfolio.  Certain
securities  held by the Funds may have remaining  maturities in excess of stated
limitations  discussed  below if  securities  provide for  adjustments  in their
interest  rates  not less  frequently  than  such  time  limitations.  Each Fund
maintains a dollar-weighted average portfolio maturity of 90 days or less.

         PRIME  MONEY  MARKET  FUND AND PRIME  VALUE  MONEY  MARKET FUND seek to
provide current income and stability of principal.  In pursuing their investment
objectives,  the  Funds  invest  in a broad  range  of  short-term  instruments,
including  U.S.  Government  and  U.S.  bank  and  commercial   obligations  and
repurchase  agreements  relating to such  obligations.  Prime Value Money Market
Fund may also invest in securities of foreign issuers. Each Fund invests only in
securities  that are  payable in U.S.  dollars  and that have (or,  pursuant  to
regulations  adopted by the SEC will be deemed to have) remaining  maturities of
thirteen months or less at the date of purchase by the Fund.

         Both  Funds  invest  in  securities  rated by the  "Requisite  NRSROs."
"Requisite  NRSROs" means (a) any two  nationally-recognized  statistical rating
organizations ("NRSROs") that have issued a rating with respect to a security or
class of debt obligations of an issuer,  or (b) one NRSRO, if only one NRSRO has
issued such a rating at the time that the Fund acquires the security. Currently,
there are six NRSROs: Standard & Poor's, a division of The McGraw-Hill Companies
("S&P"); Moody's Investors Service, Inc. ("Moody's");  Fitch Investors Services,
Inc.;  Duff and Phelps,  Inc.;  IBCA Limited and its affiliate,  IBCA,  Inc. and
Thomson  Bankwatch.  A  discussion  of the ratings  categories  of the NRSROs is
contained in the Appendix to the Statement of Additional Information.

         Prime  Money  Market  Fund will  limit  its  portfolio  investments  to
securities  that the Board of Trustees  determines  present minimal credit risks
and which are "First Tier Eligible Securities" at the time of acquisition by the
Fund. The term First Tier Eligible  Securities  includes securities rated by the
Requisite  NRSROs in the highest  short-term  rating  categories,  securities of
issuers that have  received  such rating with respect to other  short-term  debt
securities and comparable unrated securities.

         Prime Value Money Market Fund will limit its portfolio  investments  to
securities  that the Board of Trustees  determines  present minimal credit risks
and which are "Eligible  Securities" at the time of acquisition by the Fund. The
term Eligible  Securities  includes  securities rated by the Requisite NRSROs in
one of the two highest short-term rating categories,  securities of issuers that
have received such ratings with respect to other  short-term debt securities and
comparable unrated securities.

         Each Fund  generally  may not invest more than 5% of it total assets in
the  securities of any one issuer,  except for U.S.  Government  securities.  In
addition, Prime Value Money Market Fund may not invest more than 5% of its total
assets in Eligible Securities that have not received the highest rating from the
Requisite

                                        7


<PAGE>


NRSROs and comparable unrated securities  ("Second Tier Securities") and may not
invest more than 1% of its total assets in the Second Tier Securities of any one
issuer.  The  Funds  may  invest  more  than 5% (but  no more  than  25%) of the
then-current  value of the Fund's  total  assets in the  securities  of a single
issuer  for a  period  of up to  three  business  days,  provided  that  (a) the
securities  either are rated by the Requisite  NRSROs in the highest  short-term
rating category or are securities of issuers that have received such rating with
respect  to  other   short-term  debt  securities  or  are  comparable   unrated
securities,  and (b) the Fund does not make more than one such investment at any
one time.

         Each Fund may purchase  obligations of issuers in the banking industry,
such as commercial paper,  notes,  certificates of deposit,  bankers acceptances
and time deposits and U.S. dollar denominated instruments issued or supported by
the credit of the U.S. (or foreign in the case of Prime Value Money Market Fund)
banks or savings  institutions  having  total  assets at the time of purchase in
excess of $1 billion. The Funds may also make interest-bearing  savings deposits
in commercial and savings banks in amounts not in excess of 5% of their assets.

         GOVERNMENT OBLIGATIONS MONEY MARKET FUND AND TREASURY INSTRUMENTS MONEY
MARKET FUND II seek to provide  income with liquidity and security of principal.
Each Fund invests only in securities  that are payable in U.S.  dollars and that
have (or,  pursuant to  regulations  adopted by the SEC, will be deemed to have)
remaining  maturities of thirteen  months or less at the date of purchase by the
Fund (twelve months in the case of Government Obligations Money Market Fund).

         Government  Obligations Money Market Fund invests in obligations issued
or  guaranteed by the U.S.  Government,  its agencies or  instrumentalities  (in
addition to direct Treasury  obligations) and repurchase  agreements relating to
such obligations.

         Treasury  Instruments  Money  Market  Fund II invests  solely in direct
obligations  of the U.S.  Treasury,  such as  Treasury  bills and notes,  and in
repurchase  agreements  relating to direct Treasury  obligations.  The Fund will
purchase obligations of agencies or instrumentalities of the U.S. Government.

         TAX-FREE  MONEY  MARKET FUND AND  MUNICIPAL  MONEY  MARKET FUND seek to
provide  investors  with as high a level of current  income  exempt from federal
income tax as is consistent  with relative  stability of principal.  In pursuing
their investment objectives,  the Funds invest substantially all of their assets
in diversified  portfolios of short-term tax-exempt  obligations issued by or on
behalf of states, territories and possessions of the United States, the District
of Columbia, and their respective authorities,  agencies,  instrumentalities and
political  subdivisions  and  tax-exempt  derivative  securities  such as tender
option bonds,  participations,  beneficial  interests in trusts and  partnership
interests  (collectively  "Municipal  Obligations").  Each Fund  invests only in
securities  that have (or,  pursuant to regulations  adopted by the SEC, will be
deemed to have)  remaining  maturities of thirteen months or less at the date of
purchase  by the Fund.  The Funds will not  knowingly  purchase  securities  the
interest on which is subject to federal  income  tax.  Except  during  temporary
defensive periods, each Fund will invest substantially all, but in no event less
than 80%, of its net assets in Municipal Obligations. Tax-Free Money Market Fund
will not  invest in  securities  the income  from  which may be a  specific  tax
preference  item for purposes of federal  individual  and corporate  alternative
minimum  tax.  The  Funds  also  have  the  ability  to  enter  into  repurchase
agreements.  Absent emergency of extraordinary  circumstances,  however, neither
Fund  presently  intends  to  engage in  repurchase  transactions,  unless  such
transactions would not generate taxable income to such Funds.

         Both the  Tax-Free  Money Market Fund and  Municipal  Money Market Fund
purchase Municipal Obligations that present minimal credit risk as determined by
the  Adviser  pursuant to  guidelines  approved  by the Board of  Trustees.  The
Municipal Money Market Fund invests in Eligible  Securities  while the Tax- Free
Money Market Fund invests in only First Tier Eligible Securities.  The Funds may
hold uninvested cash reserves pending  investment or during temporary  defensive
periods,  including when suitable tax-exempt obligations are unavailable.  There
is no  percentage  limitation  on  the  amount  of  assets  which  may  be  held
uninvested. Uninvested cash reserves will not earn income.

                                        8


<PAGE>


         Although the Tax-Free Money Market Fund may invest more than 25% of its
net assets in (a) Municipal  Obligations whose issuers are in the same state and
(b) Municipal  Obligations the interest on which is paid solely from revenues of
similar  projects,  it does not presently intend to do so on a regular basis. To
the extent the Fund's assets are concentrated in Municipal  Obligations that are
payable from the revenues of similar  projects or are issued by issuers  located
in the same state,  the Fund will be subject to the peculiar risks  presented by
the laws and economic conditions relating to such states,  projects and bonds to
a greater extent than it would be if its assets were not so concentrated.

                       PORTFOLIO INSTRUMENTS AND PRACTICES

         Investment  strategies  that are  available  to the Funds are set forth
below.  Additional  information concerning certain of these strategies and their
related risks is contained in the Statement of Additional Information.

U.S. GOVERNMENT OBLIGATIONS

         Each Fund (other than  Municipal  Money Market Fund and Tax-Free  Money
Market  Fund)  may  purchase  obligations  issued  or  guaranteed  by  the  U.S.
Government and (except in the case of Treasury Instruments Money Market Fund II)
U.S. Government agencies and instrumentalities.  Securities issued or guaranteed
by the  U.S.  Government  or its  agencies  or  instrumentalities  include  U.S.
Treasury  securities,  which differ in interest  rates,  maturities and times of
issuance.  Treasury bills have initial maturities of one year or less;  Treasury
notes have initial  maturities of one to ten years; and Treasury bonds generally
have initial  maturities of greater than ten years.  Some obligations  issued or
guaranteed  by U.S.  Government  agencies  or  instrumentalities,  for  example,
Government  National  Mortgage  Association   pass-through   certificates,   are
supported  by the full faith and credit of the U.S.  Treasury;  others,  such as
those issued by the Federal  National  Mortgage  Association,  by  discretionary
authority of the U.S.  Government to purchase certain  obligations of the agency
or  instrumentality;  and  others,  such as those  issued  by the  Student  Loan
Marketing  Association,  only by the  credit of the  agency or  instrumentality.
These securities bear fixed,  floating or variable rates of interest.  While the
U.S.  Government  provides  financial support to such U.S.  Government-sponsored
agencies or instrumentalities,  no assurance can be given that it will always do
so,  since  it is not so  obligated  by  law.  The  Funds  will  invest  in such
securities only when they are satisfied that the credit risk with respect to the
issuer is minimal.

         Securities issued or guaranteed by the U.S. Government, its agencies or
instrumentalities have historically involved little risk of loss of principal if
held to maturity.  However,  due to fluctuations  in interest rates,  the market
value of the  securities may vary during the period an investor owns shares of a
Fund.

REPURCHASE AGREEMENTS

         The Funds may agree to purchase securities from financial  institutions
subject to the seller's  agreement to repurchase them at an agreed upon time and
price within one year from the date of  acquisition  ("repurchase  agreements").
The Funds  will not  invest  more  than 10% of the value of their net  assets in
repurchase  agreements  with terms which exceed  seven days.  The seller under a
repurchase  agreement  will be required to maintain the value of the  securities
subject  to the  agreement  at not less  than the  repurchase  price  (including
accrued interest). Default by or bankruptcy of the seller would, however, expose
the  Funds to  possible  loss  because  of  adverse  market  action  or delay in
connection with the disposition of the underlying obligations.

REVERSE REPURCHASE AGREEMENTS

         Each Fund may borrow  funds for  temporary  purposes by  entering  into
reverse  repurchase  agreements in accordance  with the investment  restrictions
described  below.  Pursuant to such  agreements,  the Funds would sell portfolio
securities to financial  institutions  and agree to repurchase them at an agreed
upon date and price. The Funds would consider  entering into reverse  repurchase
agreements to avoid  otherwise  selling  securities  during  unfavorable  market
conditions. Reverse repurchase agreements involve the risk

                                        9


<PAGE>


that the market value of the securities  sold by the Funds may decline below the
price of the  securities  the Funds are obligated to  repurchase.  The Funds may
engage in reverse repurchase  agreements provided that the amount of the reverse
repurchase  agreements and any other borrowings does not exceed one-third of the
value  of  the  Fund's  total  assets   (including  the  amount  borrowed)  less
liabilities (other than borrowings).

WHEN-ISSUED SECURITIES

         The Funds (other than Tax-Free  Money Market Fund and  Municipal  Money
Market Fund) may  purchase  securities  on a  "when-issued"  basis.  When-issued
securities are securities  purchased for delivery  beyond the normal  settlement
date at a stated  price and  yield.  The Funds will  generally  not pay for such
securities or start earning interest on them until they are received. Securities
purchased  on a  when-issued  basis are  recorded as an asset and are subject to
changes in value based upon changes in the general level of interest rates.  The
Funds expect that commitments to purchase when-issued securities will not exceed
25% of the value of their total assets absent  unusual  market  conditions.  The
Funds do not intend to purchase when-issued  securities for speculative purposes
but only in furtherance of their investment objectives.

ILLIQUID SECURITIES

         Prime Money Market Fund, Prime Value Money Market Fund,  Tax-Free Money
Market Fund and Municipal Money Market Fund will not knowingly  invest more than
10% of the value of their  total net assets in  illiquid  securities,  including
time deposits and  repurchase  agreements  having  maturities  longer than seven
days.  Securities that have readily  available market  quotations are not deemed
illiquid  for  purposes  of  this  limitation  (irrespective  of  any  legal  or
contractual  restrictions on resale). Each of the Funds may invest in commercial
obligations  issued in reliance on the so-called "private  placement"  exemption
from  registration  afforded by Section 4(2) of the  Securities  Act of 1933, as
amended ("Section 4(2) paper").  Each of the Funds may also purchase  securities
that are not registered under the Securities Act of 1933, as amended,  but which
can be sold to qualified institutional buyers in accordance with Rule 144A under
that Act  ("Rule  144A  securities").  Section  4(2) paper is  restricted  as to
disposition  under  the  federal  securities  laws,  and  generally  is  sold to
institutional investors such as the Funds who agree that they are purchasing the
paper for investment and not with a view to public  distribution.  Any resale by
the purchaser must be in an exempt  transaction.  Section 4(2) paper is normally
resold  to other  institutional  investors  like the  Fund  through  or with the
assistance of the issuer or investment  dealers who make a market in the Section
4(2) paper,  thus providing  liquidity.  Rule 144A securities  generally must be
sold to other  qualified  institutional  buyers.  If a particular  investment in
Section 4(2) paper or Rule 144A securities is not determined to be liquid,  that
investment  will be included  within the percentage  limitation on investment in
illiquid securities.

FOREIGN SECURITIES

         Prime Value Money Market Fund may invest substantially in securities of
foreign issuers,  including  obligations of foreign banks or foreign branches of
U.S. banks, and debt securities of foreign issuers,  where the Adviser deems the
instrument  to present  minimal  credit risks.  Investments  in foreign banks or
foreign  issuers   present   certain  risks,   including  those  resulting  from
fluctuations  in currency  exchange  rates,  revaluation of  currencies,  future
political  and economic  developments  and the possible  imposition  of currency
exchange  blockages  or other  foreign  governmental  laws or  restrictions  and
reduced  availability of public  information.  Foreign issuers are not generally
subject to uniform accounting,  auditing and financial reporting standards or to
other regulatory practices and requirements applicable to domestic issuers.

ZERO COUPON AND CAPITAL APPRECIATION BONDS

         The Funds may invest in zero  coupon and  capital  appreciation  bonds,
which are debt securities issued or sold at a discount from their face value and
which do not entitle  the holder to any  periodic  payment of interest  prior to
maturity or a specified  redemption  date (or cash payment date).  The amount of
the discount  varies  depending  on the time  remaining  until  maturity or cash
payment date,  prevailing  interest rates, the liquidity of the security and the
perceived credit quality of the issuer. These securities may also take the

                                       10


<PAGE>


form of debt  securities  that have been  stripped of their  unmatured  interest
coupons,  the  coupons  themselves  or  receipts  or  certificates  representing
interest in such stripped debt obligations or coupons. Discounts with respect to
stripped  tax-exempt  securities  or their  coupons may be  taxable.  The market
prices of capital appreciation bonds generally are more volatile than the market
prices of  interest-bearing  securities  and are  likely to respond to a greater
degree to changes in  interest  rates than  interest-bearing  securities  having
similar maturity and credit quality.

U.S. TREASURY STRIPS

         The Prime Money Market Fund, Prime Value Money Market Fund,  Government
Obligations Money Market Fund and Treasury  Instruments Money Market Fund II may
invest in  separately  traded  principal  and interest  components of securities
backed by the full  faith and credit of the U.S.  Treasury.  The  principal  and
interest  components of U.S. Treasury bonds with remaining  maturities of longer
than ten  years  are  eligible  to be traded  independently  under the  Separate
Trading of Registered  Interest and Principal of Securities  ("STRIPS") program.
Under the STRIPS program,  the principal and interest  components are separately
issued by the U.S. Treasury at the request of depository financial institutions,
which then trade the component parts  separately.  Under the stripped bond rules
of the Internal  Revenue Code of 1986, as amended (the "Code"),  investments  by
the Funds in  STRIPS  will  result in the  accrual  of  interest  income on such
investments in advance of the receipt of the cash  corresponding to such income.
The interest component of STRIPS may be more volatile than that of U.S. Treasury
bills with  comparable  maturities.  In  accordance  with Rule 2a-7,  the Funds'
investments  in  STRIPS  are  limited  to those  with  maturity  components  not
exceeding thirteen months.

LENDING OF PORTFOLIO SECURITIES

         Each Fund may lend portfolio securities up to one-third of the value of
its  total   assets  to  U.S.  and  foreign   broker/dealers,   banks  or  other
institutional borrowers of securities that the Adviser has determined are credit
worthy under  guidelines  established  by the Board of Trustees.  The Funds will
receive  collateral in the form of cash, letters of credit, or securities of the
U.S.  Government  or its  agencies  equal to at least  100% of the  value of the
securities owned.

VARIABLE AND FLOATING RATE SECURITIES

         The interest  rates payable on certain  securities in which Prime Money
Market Fund, Prime Value Money Market Fund, Government  Obligations Money Market
Fund,  Tax-Free Money Market Fund and Municipal Money Market Fund may invest are
not fixed and may fluctuate  based upon changes in market rates. A variable rate
obligation  has an interest  rate which is adjusted  at  predesignated  periods.
Interest on a floating rate obligation is adjusted whenever there is a change in
the  market  rate of  interest  on which the  interest  rate  payable  is based.
Tax-exempt variable or floating rate obligations generally permit the holders of
such obligations to demand payment of principal from the issuer or a third party
at stated  intervals.  Variable and floating rate obligations are less effective
than fixed rate instruments at locking in a particular  yield.  Such obligations
may  fluctuate in value in response to interest rate changes if there is a delay
between  changes in market  interest  rates and the interest  reset date for the
obligation.  The Funds will take demand or reset features into  consideration in
determining  the  average  portfolio  duration  of the  Fund  and the  effective
maturity of individual securities.  In addition, the absence of an unconditional
demand feature  exercisable within seven days will require a tax-exempt variable
or floating  rate  obligation to be treated as illiquid for purposes of a Fund's
limitation on illiquid  investments.  The failure of the issuer or a third party
to  honor  its  obligations  under a  demand  or put  feature  might  require  a
tax-exempt  variable or floating  rate  obligation to be treated as illiquid for
purposes of a Fund's limitation on illiquid investments.

TAX-EXEMPT COMMERCIAL PAPER

         Tax-Free  Money Market Fund and Municipal  Money Market Fund may invest
in tax-exempt  commercial paper.  Issues of commercial paper typically represent
short-term, unsecured, negotiable promissory notes. These obligations are issued
by state and local governments and their agencies to finance

                                       11


<PAGE>


working  capital  needs of  municipalities  or to provide  interim  construction
financing and are paid from general or specific  revenues of  municipalities  or
are re-financed with long-term debt. In some cases,  tax-exempt commercial paper
is backed by letters of credit,  lending agreements,  note repurchase agreements
or other credit facility  arrangements  offered by banks or other  institutions.
The Funds will invest only in tax-exempt commercial paper rated at least Prime-2
by Moody's or A-2 by S&P.

MUNICIPAL OBLIGATIONS

         Tax-Free  Money Market Fund and Municipal  Money Market Fund may invest
in the Municipal Obligations described below.

         Municipal  Obligations.  Municipal Obligations include bonds, notes and
other instruments issued by or on behalf of states,  territories and possessions
of the United States  (including  the District of Columbia) and their  political
subdivisions,  agencies or  instrumentalities,  the interest on which is, in the
opinion of bond counsel,  exempt from regular federal income tax (i.e., excluded
from gross income for federal  income tax purposes  but not  necessarily  exempt
from the personal  income  taxes of any state or, with respect to the  Municipal
Money Market  Fund,  from the federal  alternative  minimum  tax).  In addition,
Municipal  Obligations  include  participation  interests in such securities the
interest on which is, in the opinion of bond  counsel for the issuers or counsel
selected by the Adviser,  exempt from regular federal income tax. The definition
of Municipal Obligations includes other types of securities that currently exist
or may be  developed  in the future and that are,  or will be, in the opinion of
counsel,  as described above,  exempt from regular federal income tax,  provided
that  investing  in such  securities  is  consistent  with a  Fund's  investment
objective and policies.

         The two principal classifications of Municipal Obligations which may be
held by the Funds are "general obligation"  securities and "revenue" securities.
General  obligation  securities  are secured by the issuer's  pledge of its full
faith,  credit  and taxing  power for the  payment of  principal  and  interest.
Revenue  securities are payable only from the revenues derived from a particular
facility  or class of  facilities,  or in some  cases,  from the  proceeds  of a
special  excise tax or other  specific  revenue  source  such as the user of the
facility being financed. Revenue securities include private activity bonds which
may be held by the  Municipal  Money  Market Fund and which are not payable from
the unrestricted  revenues of the issuer.  While some private activity bonds are
general  obligation  securities,  the  vast  majority  are  revenue  securities.
Consequently,  the credit quality of private  activity bonds is usually directly
related to the credit  standing of the corporate user of the facility  involved.
Each of the Municipal  Obligations  described  below may take the form of either
general obligation or revenue securities.

         Municipal  Obligations  are often  issued to obtain  funds for  various
public purposes, including the construction of a wide range of public facilities
such as bridges,  highways,  housing,  hospitals, mass transportation,  schools,
streets and water and sewer  works.  Other public  purposes for which  Municipal
Obligations may be issued include refunding outstanding  obligations,  obtaining
funds for  general  operating  expenses,  and  obtaining  funds to lend to other
public   institutions  and  facilities.   Municipal   Obligations  also  include
industrial  development  bonds,  or with respect to the  Municipal  Money Market
Fund,  private  activity  bonds,  which  are  issued  by or on  behalf of public
authorities to obtain funds for privately-operated housing facilities,  airport,
mass  transit or port  facilities,  sewage  disposal,  solid  waste  disposal or
hazardous  waste treatment or disposal  facilities and certain local  facilities
for  water  supply,  gas  or  electricity.  In  addition,  proceeds  of  certain
industrial development bonds are used for the construction, equipment, repair or
improvement  of privately  operated  industrial  or commercial  facilities.  The
interest income from private activity bonds may subject certain investors to the
federal alternative minimum tax.

         Municipal Leases, Certificates of Participation and Other Participation
Interests.  The Funds  may  invest  in  municipal  leases  and  certificates  of
participation  in municipal  leases.  A municipal  lease is an obligation in the
form of a lease or  installment  purchase  which is  issued  by a state or local
government to acquire equipment and facilities.  Income from such obligations is
generally exempt from state and local taxes in the state of issuance.  Municipal
leases  frequently  involve  special risks not normally  associated with general
obligation or revenue bonds. Leases and installment purchase or conditional sale
contracts (which

                                       12


<PAGE>


normally  provide  for  title  to the  leased  asset to pass  eventually  to the
governmental issuer) have evolved as a means for governmental issuers to acquire
property  and  equipment  without  meeting  the   constitutional  and  statutory
requirements for the issuance of debt. The debt issuance  limitations are deemed
to be  inapplicable  because of the  inclusion  in many leases or  contracts  of
"non-appropriation"   clauses  that  relieve  the  governmental  issuer  of  any
obligation to make future  payments under the lease or contract  unless money is
appropriated for such purpose by the appropriate legislative body on a yearly or
other periodic  basis.  In addition,  such leases or contracts may be subject to
the  temporary  abatement of payments in the event the issuer is prevented  from
maintaining  occupancy of the leased premises or utilizing the leased equipment.
Although the  obligation  may be secured by the leased  equipment or facilities,
the disposition of the property in the event of  nonappropriation or foreclosure
might  prove   difficult,   time   consuming  and  costly,   and  result  in  an
unsatisfactory or delayed recoupment of the Fund's original investment.

         Certificates  of  participation   represent   undivided   interests  in
municipal leases,  installment  purchase  agreements or other  instruments.  The
certificates  are typically issued by a trust or other entity which has received
an assignment  of the payments to be made by the state or political  subdivision
under such leases or installment purchase agreements.

         Certain  municipal lease  obligations and certificates of participation
may be deemed illiquid for the purpose of a Fund's  limitation on investments in
illiquid  securities.  Other  municipal lease  obligations  and  certificates of
participation  acquired by the Funds may be determined by the Adviser,  pursuant
to guidelines adopted by the Board of Trustees,  to be liquid securities for the
purpose of such  limitation.  In  determining  the liquidity of municipal  lease
obligations  and  certificates  of  participation,  the Adviser will  consider a
variety  of  factors  including  (a) the  willingness  of dealers to bid for the
security,  (b) the number of dealers  willing to purchase or sell the obligation
and the number of other potential buyers,  (c) the frequency of trades or quotes
for the obligation,  and (d) the nature of marketplace trades. In addition,  the
Adviser  will  consider  factors  unique to  particular  lease  obligations  and
certificates of participation affecting the marketability thereof. These include
the general  creditworthiness  of the issuer,  the  importance  of the  property
covered by the lease to the issuer and the likelihood that the  marketability of
the obligation will be maintained  throughout the time the obligation is held by
the Funds.

         The Funds may also  purchase  participations  in Municipal  Obligations
held by a commercial bank or other financial  institution.  Such  participations
provide  the  Funds  with  the  right to a pro rata  undivided  interest  in the
underlying Municipal  Obligations.  In addition,  such participations  generally
provide the Funds with the right to demand payment,  on not more than seven days
notice, of all or any part of a Fund's participation  interest in the underlying
Municipal Obligation, plus accrued interest. These demand features will be taken
into consideration in determining the effective maturity of such  participations
and the average  portfolio  duration of the Funds. The Funds will only invest in
such  participations  if, in the  opinion  of bond  counsel  for the  issuers or
counsel selected by the Adviser, the interest from such participations is exempt
from regular federal income tax.

         Municipal  Notes.  Municipal  Obligations  purchased  by the  Funds may
include  fixed-rate notes or variable-rate  demand notes.  Such notes may not be
rated by credit rating  agencies,  but unrated notes purchased by the Funds will
be determined by the Adviser to be of comparable quality at the time of purchase
to rated instruments purchasable by the Funds. Where necessary to determine that
a note is an Eligible Security or First Tier Eligible  Security,  the Funds will
require the issuer's obligation to pay the principal of the note be backed by an
unconditional  bank letter or line of credit,  guarantee or  commitment to lend.
While  there may be no active  secondary  market  with  respect to a  particular
variable  rate demand note  purchased by the Funds,  the Funds may,  upon notice
specified in the note,  demand  payment of the principal of the note at any time
or during specified  periods not exceeding  thirteen months,  depending upon the
instrument  involved,  and may resell the note at any time to a third party. The
absence of such an active secondary market, however, could make it difficult for
the Funds to dispose  of a  variable  rate  demand  note if the  issuer  were to
default  on its  payment  obligation  or during  periods  that the Funds are not
entitled to exercise their demand rights, and the Funds could, for this or other
reasons, suffer losses to the extent of the default.

                                       13


<PAGE>


         Pre-Refunded   Municipal   Obligations.   The  Funds   may   invest  in
pre-refunded   Municipal   Obligations.   The   principal  of  and  interest  on
pre-refunded  Municipal Obligations are no longer paid from the original revenue
source for the Municipal  Obligations.  Instead,  the source of such payments is
typically an escrow fund  consisting of obligations  issued or guaranteed by the
U.S. Government.  The assets in the escrow fund are derived from the proceeds of
refunding  bonds  issued  by  the  same  issuer  as the  pre-refunded  Municipal
Obligations,  but  usually on terms more  favorable  to the  issuer.  Issuers of
Municipal  Obligations  use this  advance  refunding  technique  to obtain  more
favorable terms with respect to Municipal  Obligations which are not yet subject
to call or redemption by the issuer.  For example,  advance refunding enables an
issuer to refinance debt at lower market  interest  rates,  restructure  debt to
improve cash flow or eliminate  restrictive  covenants in the indenture or other
governing instrument for the pre-refunded Municipal Obligations. However, except
for a change in the revenue  source from which  principal and interest  payments
are made, the pre-refunded  Municipal  Obligations  remain  outstanding on their
original  terms until they mature or are redeemed by the issuer.  The  effective
maturity of pre-refunded  Municipal  Obligations  will be the redemption date if
the issuer has assumed an  obligation  or indicated its intention to redeem such
obligations on the redemption date. Pre-refunded Municipal Obligations are often
purchased at a price which represents a premium over their face value.

         Tender Option  Bonds.  The Funds may purchase  tender  option bonds.  A
tender  option  bond is a Municipal  Obligation  (generally  held  pursuant to a
custodial arrangement) having a relatively long maturity and bearing interest at
a fixed rate substantially higher than prevailing  short-term  tax-exempt rates,
that has been  coupled  with the  agreement  of a third  party,  such as a bank,
broker-dealer or other financial institution, pursuant to which such institution
grants the security holders the option, at periodic  intervals,  to tender their
securities  to  the  institution   and  receive  the  face  value  thereof.   As
consideration  for providing  the option,  the  financial  institution  receives
periodic fees equal to the difference  between the Municipal  Obligation's fixed
coupon rate and the rate, as determined by a remarketing  or similar agent at or
near the commencement of such period,  that would cause the securities,  coupled
with  the  tender  option,  to  trade  at or  near  par  on  the  date  of  such
determination.  Thus, after payment of this fee, the security holder effectively
holds a demand  obligation  that bears  interest  at the  prevailing  short-term
tax-exempt   rate.   The  Adviser  will   consider  on  an  ongoing   basis  the
creditworthiness of the issuer of the underlying  Municipal  Obligation,  of any
custodian  and of the third  party  provider  of the tender  option.  In certain
instances and for certain  tender option bonds,  the option may be terminable in
the event of a default in payment of  principal  or interest  on the  underlying
Municipal Obligations and for other reasons. Additionally, the above description
of tender  option  bonds is meant only to  provide  an  example of one  possible
structure of such  obligations,  and the Funds may purchase  tender option bonds
with   different   types  of  ownership,   payment,   credit  and/or   liquidity
arrangements.

                             INVESTMENT LIMITATIONS

         The Funds' investment  objectives and policies  described above are not
fundamental  and may be  changed  by the  Board of  Trustees  without  a vote of
shareholders.  If there  is a  change  in the  investment  objective  of a Fund,
shareholders should consider whether the Fund remains an appropriate  investment
in light of  their  then  current  financial  position  and  needs.  The  Funds'
investment   limitations   described  below  may  not  be  changed  without  the
affirmative vote of the holders of a majority of its outstanding  shares.  There
can be no assurance that the Funds will achieve their investment objectives.  (A
complete list of the  investment  limitations  that cannot be changed  without a
vote of  shareholders  is contained in the Statement of  Additional  Information
under "Investment Objectives and Policies.")

         The Funds may not:

         1. Borrow money,  except that a Fund may (i) borrow money for temporary
or emergency  purposes (not for leveraging or investment) from banks, or subject
to specific  authorization  by the SEC,  from funds advised by the Adviser or an
affiliate  of the  Adviser,  and (ii) engage in reverse  repurchase  agreements;
provided that (i) and (ii) in combination  do not exceed  one-third of the value
of the Fund's total assets  (including  the amount  borrowed)  less  liabilities
(other than borrowings). The Funds may not mortgage,

                                       14


<PAGE>


pledge or hypothecate  any assets except in connection  with such borrowings and
reverse repurchase  agreements and then only in amounts not exceeding  one-third
of the  value  of the  particular  Fund's  total  assets  at the  time  of  such
borrowing.  Additional  investments  will not be made by a Fund when  borrowings
exceed 5% of the Fund's assets.

         2. Purchase any  securities  which would cause 25% or more of the value
of its  total  assets  at the  time  of  such  purchase  to be  invested  in the
securities of one or more issuers conducting their principal business activities
in the same industry,  except that Prime Value Money Market Fund will invest 25%
or more of the  value of its total  assets  in  obligations  of  issuers  in the
banking industry or in obligations,  such as repurchase  agreements,  secured by
such  obligations  (unless  the  Fund  is in a  temporary  defensive  position);
provided  that  there is no  limitation  with  respect  to  investments  in U.S.
Government  securities  or,  in the case of Prime  Money  Market  Fund,  in bank
instruments issued by domestic banks.

         3.  Make  loans  except  that a Fund  may (i)  purchase  or  hold  debt
obligations in accordance with its investment objective and policies, (ii) enter
into repurchase  agreements for securities,  (iii) lend portfolio securities and
(iv) with the exception of Government  Obligations Money Market Fund, subject to
specific  authorization  by the SEC,  lend money to other  funds  advised by the
Adviser or an affiliate of the Adviser.

         Each Fund may, in the future, seek to achieve its investment  objective
by  investing  all of its assets in a no-load,  open-end  management  investment
company having the same investment  objective and policies and substantially the
same  investment  restrictions  as those  applicable to the Fund. In such event,
each Fund's investment  advisory agreement would be terminated.  Such investment
would be made only if the Trust's Board of Trustees  believes that the aggregate
per share expenses of each class of the Fund and such other  investment  company
will be less than or approximately equal to the expenses which each class of the
Fund  would  incur if the Fund were to  continue  to retain the  services  of an
investment  adviser  for the Fund and the assets of the Fund were to continue to
be invested directly in portfolio securities.

                        PURCHASE AND REDEMPTION OF SHARES

         To allow the  Adviser to manage the Funds  effectively,  investors  are
strongly  urged to initiate all  investments  or  redemptions  of Fund shares as
early in the day as possible and to notify  Lehman  Brothers at least one day in
advance of transactions in excess of $5 million.

PURCHASE PROCEDURES

         Shares of the  Funds  are sold at the net asset  value per share of the
Fund next determined after receipt of a purchase order by Lehman  Brothers,  the
Distributor of the Fund's shares.  Purchase  orders for shares are accepted only
on days on which both the New York Stock  Exchange and the Federal  Reserve Bank
of Boston are open for business and must be transmitted to Lehman  Brothers,  by
telephone at 1-800-851-3134 or through Lehman Brothers ExpressNET,  an automated
order entry system  designed  specifically  for the Trust ("LEX").  Purchases of
shares  will be  effective  and  dividends  will  begin to accrue on the date of
purchase if purchase orders comply with the following schedule.

         Payment for Fund shares may be made only in federal  funds  immediately
available to Boston Safe Deposit and Trust Company ("Boston Safe"). (Payment for
orders  which are not received or accepted by Lehman  Brothers  will be returned
after prompt inquiry to the sending  institution.)  A Fund may in its discretion
reject any order for shares.  Any person  entitled to receive  compensation  for
selling or servicing shares of the Funds may receive different  compensation for
selling or servicing one Class of shares over another Class.

         The minimum aggregate initial investment by an institution in the Funds
is $1 million  (with not less than $25,000  invested in any one Fund);  however,
broker-dealers  and other  institutional  investors may set a higher minimum for
their customers.  To reach the minimum Trust-wide initial investment,  purchases
of shares may be  aggregated  over a period of six  months.  There is no minimum
subsequent investment.

         Conflicts  of  interest  restrictions  may  apply  to an  institution's
receipt of  compensation  paid by the Funds on fiduciary funds that are invested
in Class C Shares. See also "Management of the Funds -- Service  Organizations."
Institutions,  including  banks regulated by the Comptroller of the Currency and
investment  advisers and other money managers subject to the jurisdiction of the
SEC,  the  Department  of Labor or state  securities  commissions,  are urged to
consult their legal advisers before investing fiduciary funds in Class C Shares.

REDEMPTION PROCEDURES

         Redemption  orders must be transmitted to Lehman  Brothers by telephone
at  1-800-851-3134 or through LEX on a day that both the New York Stock Exchange

- ----------
* All times stated are Eastern time.

         Shares are  redeemed at the net asset  value per share next  determined
after Lehman Brothers' receipt of the redemption  order.  While the Funds intend
to use their best efforts to maintain  their net asset value per share at $1.00,
the proceeds  paid to an investor upon  redemption  may be more or less than the
amount  invested  depending  upon a  share's  net  asset  value  at the  time of
redemption.

         The Funds reserve the right to wire  redemption  proceeds  within seven
days after receiving the redemption order if, in the judgment of the Adviser, an
earlier payment could adversely affect the Funds. The Funds shall have the right
to redeem  involuntarily  shares in any  account at their net asset value if the
value of the account is less than $10,000 after 60 days' prior written notice to
the investor.  Any such redemption  shall be effected at the net asset value per
share next  determined  after the  redemption  order is  entered.  If during the
60-day  period the  investor  increases  the value of its  account to $10,000 or
more, no such  redemption  shall take place.  In addition,  the Funds may redeem
shares  involuntarily  or suspend the right of redemption as permitted under the
Investment  Company Act of 1940,  as amended (the "1940 Act"),  or under certain
special circumstances described in the Statement of Additional Information under
"Additional Purchase and Redemption Information."

<PAGE>


         The ability to give  telephone  instructions  for the  redemption  (and
purchase or exchange) of shares is  automatically  established  on an investor's
account.  However,  the Funds  reserve  the right to refuse a  redemption  order
transmitted  by telephone if it is believed  advisable to do so.  Procedures for
redeeming  Fund shares by telephone may be modified or terminated at any time by
the Funds or Lehman Brothers.  In addition,  neither the Funds,  Lehman Brothers
nor First Data Investor Services Group,  Inc.  ("FDISG") will be responsible for
the  authenticity  of telephone  instructions  for the  purchase,  redemption or
exchange of shares where the instructions are reasonably believed to be genuine.
Accordingly,  the investor will bear the risk of loss. The Funds will attempt to
confirm that telephone  instructions are genuine and will use such procedures as
are considered reasonable, including the recording of telephone instructions. To
the  extent  that the Funds  fail to use  reasonable  procedures  to verify  the
genuineness of telephone instructions,  the Funds or their service providers may
be liable for such instructions that prove to be fraudulent or unauthorized.

EXCHANGE PROCEDURES

         The Exchange Privilege enables an investor to exchange shares of a Fund
without  charge for shares of the same class of other Funds which have different
investment objectives that may be of interest to investors.  To use the Exchange
Privilege,  exchange  instructions must be given to Lehman Brothers by telephone
or through LEX. See "Redemption  Procedures." In exchanging  shares, an investor
must meet the minimum initial  investment  requirement of the other Fund and the
shares  involved  must be  legally  available  for sale in the  state  where the
investor resides.  Before any exchange, the investor must also obtain and should
review  a copy of the  current  prospectus  of the  Funds.  Prospectuses  may be
obtained  from  Lehman  Brothers  by  calling  1-800-368-5556.  Shares  will  be
exchanged at the net asset value next  determined  after  receipt of an exchange
request in proper form. The exchange of shares of one Fund for shares of another
Fund is treated for federal income tax purposes as a sale of the shares given in
exchange by the investor and, therefore,  an investor may realize a taxable gain
or loss. The Funds reserve the right to reject any exchange  request in whole or
in part.  The Exchange  Privilege may be modified or terminated at any time upon
notice to investors.

VALUATION OF SHARES -- NET ASSET VALUE

         Each Fund's net asset value per share for purposes of pricing  purchase
and redemption orders is determined by the Fund's Administrator on each weekday,
with the exception of those holidays on which either the New York Stock Exchange
or the Federal  Reserve  Bank of Boston is closed,  according  to the  following
schedule.

* All times stated are Eastern time.

         Currently,  one or both of the New York Stock  Exchange and the Federal
Reserve Bank of Boston are closed on the customary national business holidays of
New Year's Day, Martin Luther King, Jr.'s Birthday  (observed),  Presidents' Day
(Washington's Birthday), Good Friday, Memorial Day, Independence Day,

                                       17


<PAGE>


Labor Day, Columbus Day (observed), Veterans Day, Thanksgiving Day and Christmas
Day, and on the preceding Friday or subsequent Monday when one of these holidays
falls on a Saturday  or Sunday,  respectively.  The net asset value per share of
Fund shares is calculated  separately  for each class by adding the value of all
securities and other assets of the Fund, subtracting class specific liabilities,
and dividing the result by the total number of the Fund's outstanding shares. In
computing net asset value, each Fund uses the amortized cost method of valuation
as  described in the  Statement  of  Additional  Information  under  "Additional
Purchase  and  Redemption  Information."  A Fund's net asset value per share for
purposes of pricing purchase and redemption  orders is determined  independently
of the net asset values of the shares of each other Fund.

OTHER MATTERS

         Fund  shares  are  sold  and  redeemed  without  charge  by the  Funds.
Institutional  investors  purchasing  or holding Fund shares for their  customer
accounts  may  charge  customers  fees for cash  management  and other  services
provided  in  connection  with their  accounts.  A customer  should,  therefore,
consider the terms of its account with an  institution  before  purchasing  Fund
shares.  An  institution  purchasing  or redeeming  Fund shares on behalf of its
customers  is  responsible  for  transmitting   orders  to  Lehman  Brothers  in
accordance with its customer agreements.

                                    DIVIDENDS

         Investors of a Fund are entitled to dividends and distributions arising
only  from the net  investment  income  and  capital  gains,  if any,  earned on
investments  held by that Fund.  Each Fund's net  investment  income is declared
daily as a dividend  to shares  held of record at the close of  business  on the
date of  declaration.  Shares begin  accruing  dividends on the day the purchase
order for the shares is effective and continue to accrue  dividends  through the
day before such shares are redeemed. Dividends are paid monthly by wire transfer
within five  business  days after the end of the month or within  five  business
days after a redemption  of all of an investor's  shares of a particular  class.
The Funds do not expect to realize net long-term capital gains.

         Dividends  are  determined  in the same manner and are paid in the same
amount  for each Fund  share,  except  that  shares of each  class  bear all the
expenses associated with that specific class.

         Institutional investors may elect to have their dividends reinvested in
additional  full and fractional  shares of the same class of shares with respect
to which such  dividends  are  declared at the net asset value of such shares on
the  payment  date.  Reinvested  dividends  receive  the same tax  treatment  as
dividends paid in cash. Such election,  or any revocation thereof,  must be made
in  writing  to Lehman  Brothers,  260  Franklin  Street,  15th  Floor,  Boston,
Massachusetts 02110-9624,  and will become effective after its receipt by Lehman
Brothers, with respect to dividends paid.

         FDISG,  as Transfer  Agent,  will send each investor or its  authorized
representative  an annual statement  designating the amount of any dividends and
capital gains distributions, if any, made during each year and their federal tax
qualification.

                                      TAXES

         Each Fund  qualified in its last taxable year and intends to qualify in
future years as a  "regulated  investment  company"  under the Code. A regulated
investment  company is exempt from federal income tax on amounts  distributed to
its investors.

         Qualification  as a regulated  investment  company under the Code for a
taxable  year  requires,  among  other  things,  that a Fund  distribute  to its
investors at least 90% of its investment  company  taxable income for such year.
In  general,  a Fund's  investment  company  taxable  income will be its taxable
income  (including  dividends and short-term  capital gains,  if any) subject to
certain  adjustments and excluding the excess of any net long-term capital gains
for the taxable  year over the net  short-term  capital  loss,  if any, for such
year.

                                       18


<PAGE>


Each Fund intends to  distribute  substantially  all of its  investment  company
taxable income each year. Such  distributions will be taxable as ordinary income
to Fund  investors  who are not  currently  exempt from  federal  income  taxes,
whether such income is received in cash or reinvested in additional  shares.  It
is  anticipated  that none of a Fund's  distributions  will be eligible  for the
dividends  received  deduction  for  corporations.  The  Funds do not  expect to
realize long-term capital gains and,  therefore,  do not contemplate  payment of
any "capital gain dividends" as described in the Code.

         Dividends  derived  from  exempt-interest  income from  Tax-Free  Money
Market  Fund and  Municipal  Money  Market  Fund may be  treated  by the  Fund's
investors as items of interest  excludable from their gross income under Section
103(a) of the Code, unless under the circumstances  applicable to the particular
investor the exclusion would be disallowed.

         Municipal  Money Market Fund may hold  without  limit  certain  private
activity bonds issued after August 7, 1986.  Investors must include,  as an item
of  tax  preference,  the  portion  of  dividends  paid  by  the  Fund  that  is
attributable to interest on such bonds in determining liability (if any) for the
federal  alternative  minimum tax.  Noncorporate  taxpayers,  depending on their
individual tax status,  may be subject to  alternative  minimum tax at a blended
rate between 26% and 28%. Corporate  taxpayers may be subject to (1) alternative
minimum tax at a rate of 20% of the excess of their alternative  minimum taxable
income  ("AMTI")  over the  exemption  amount,  and (2) the  environmental  tax.
Corporate investors must also take all exempt-interest dividends into account in
determining   certain   adjustments   for   federal   alternative   minimum  and
environmental tax purposes.  The environmental tax applicable to corporations is
imposed at the rate of .12% on the excess of the corporation's  modified federal
alternative  minimum taxable income over $2,000,000.  Investors receiving Social
Security benefits should note that all  exempt-interest  dividends will be taken
into account in determining the taxability of such benefits.

         To the extent,  if any,  dividends  paid to investors by Tax-Free Money
Market Fund or Municipal  Money  Market Fund are derived from taxable  income or
from long-term or short-term  capital  gains,  such dividends will not be exempt
from federal income tax,  whether such dividends are paid in the form of cash or
additional shares, and may also be subject to state and local taxes.

         In addition  to federal  taxes,  an  investor  may be subject to state,
local or foreign  taxes on payments  received from a Fund. A state tax exemption
may be  available  in some  states to the extent  distributions  of the Fund are
derived from  interest on certain U.S.  Government  securities  or on securities
issued by public  authorities  in the state.  The Funds will  provide  investors
annually with information about federal income tax consequences of distributions
made each year.  Investors should be aware of the application of their state and
local tax laws to investments in the Funds.

         Investors  will be advised at least  annually as to the federal  income
tax status of distributions made to them each year.

         The  foregoing  discussion  is  only a  brief  summary  of  some of the
important  federal  tax  considerations  generally  affecting  a  Fund  and  its
shareholders.  No  attempt  is made to  present a  detailed  explanation  of the
federal,  state or local income tax  treatment of a Fund or its  investors,  and
this  discussion  is not  intended as a  substitute  for  careful tax  planning.
Accordingly,  potential investors in the Funds should consult their tax advisers
with  specific  reference  to their  own tax  situation.  See the  Statement  of
Additional Information for a further discussion of tax consequences of investing
in shares of the Funds.

                             MANAGEMENT OF THE FUNDS

         The business and affairs of the Funds are managed  under the  direction
of  the  Trust's  Board  of  Trustees.  The  Trustees  approve  all  significant
agreements  between the Trust and the persons or companies that furnish services
to the Funds, including agreements with its Distributor, Adviser, Administrator,
Transfer  Agent  and  Custodian.  The  day-to-day  operations  of the  Funds are
delegated to the Funds' Adviser and  Administrator.  The Statement of Additional
Information contains general background  information  regarding each Trustee and
executive officer of the Trust.

                                       20


<PAGE>


certain services to the Funds and holders of Class C Shares. Lehman Brothers may
retain all the payments  made to it under the Plan or may enter into  agreements
with and make payments of up to .35% to  institutional  investors such as banks,
savings  and  loan  associations  and  other  financial  institutions  ("Service
Organizations") for the provision of a portion of such services. These services,
which are described more fully in the Statement of Additional  Information under
"Management  of the Funds -- Service  Organizations,"  include  aggregating  and
processing  purchase and redemption  requests from  shareholders and placing net
purchase  and  redemption  orders  with  Lehman  Brothers;  processing  dividend
payments  from the  Funds  on  behalf  of  shareholders;  providing  information
periodically  to shareholders  showing their positions in shares;  arranging for
bank  wires;  responding  to  shareholder  inquiries  relating  to the  services
provided  by  Lehman   Brothers  or  the  Service   Organization   and  handling
correspondence;  and acting as shareholder of record and nominee.  The Plan also
allows Lehman Brothers to use its own resources to provide distribution services
and  shareholder  services.  Under  the  terms of  related  agreements,  Service
Organizations  are required to provide to their  shareholders  a schedule of any
fees that they may charge  shareholders in connection with their  investments in
Class C Shares.

EXPENSES

         Each Fund bears all its own expenses.  A Fund's expenses include taxes,
interest,  fees and  salaries of the Trust's  trustees  and officers who are not
directors,  officers or employees of the Fund's service  contractors,  SEC fees,
state   securities   qualification   fees,   costs  of  preparing  and  printing
prospectuses  for  regulatory   purposes  and  for  distribution  to  investors,
advisory,  administration  and  distribution  fees,  charges  of the  custodian,
administrator,   transfer   agent  and  dividend   disbursing   agent,   Service
Organization  fees,  certain  insurance  premiums,  outside  auditing  and legal
expenses,  costs  of  shareholder  reports  and  shareholder  meetings  and  any
extraordinary  expenses.  Each Fund also pays for brokerage fees and commissions
(if any) in connection  with the purchase and sale of portfolio  securities.  In
order to maintain a competitive  expense  ratio,  the Adviser and  Administrator
have  voluntarily  agreed to waive  fees and  reimburse  expenses  to the extent
necessary  to maintain an  annualized  expense  ratio at a level no greater than
 .53% of average daily net assets (.18%  excluding  Rule 12b-1 fees) with respect
to the Funds.  This voluntary waiver and  reimbursement  arrangement will not be
changed  unless  investors  are provided at least 60 days'  advance  notice.  In
addition,  these  service  providers  have agreed to reimburse  the Funds to the
extent required by applicable  state law for certain expenses that are described
in the  Statement  of  Additional  Information.  Any  fees  charged  by  Service
Organizations or other institutional  investors to their customers in connection
with investments in Fund shares are not reflected in a Fund's expenses.

                             PERFORMANCE AND YIELDS

         From time to time, the "yields" and "effective  yields" with respect to
all Funds and "tax-equivalent yields" with respect to Tax-Free Money Market Fund
and Municipal Money Market Fund, may be quoted in  advertisements  or in reports
to  shareholders.  Yield  quotations  are computed  separately for each class of
shares.  The "yield" quoted in  advertisements  for a particular class of shares
refers to the income  generated by an investment in such shares over a specified
period (such as a seven-day period) identified in the advertisement. This income
is then  "annualized;" that is, the amount of income generated by the investment
during that period is assumed to be generated each such period over a 52-week or
one-year period and is shown as a percentage of the  investment.  The "effective
yield" is calculated  similarly  but, when  annualized,  the income earned by an
investment in a particular  class is assumed to be  reinvested.  The  "effective
yield" will be  slightly  higher  than the  "yield"  because of the  compounding
effect of this assumed reinvestment. The "tax-equivalent yield" demonstrates the
level of taxable yield necessary to produce an after-tax  yield  equivalent to a
Fund's  tax-free yield for each class of shares.  It is calculated by increasing
the yield  (calculated as above) by the amount  necessary to reflect the payment
of federal  taxes at a stated rate.  The  "tax-equivalent  yield" will always be
higher than the "yield."

         A Fund's  performance  may be compared to those of other  mutual  funds
with similar  objectives,  to other relevant indices, or to rankings prepared by
independent  services or other financial or industry  publications  that monitor
the performance of mutual funds. For example, such data are reported in national
financial

                                       21


<PAGE>


publications  such as Morningstar,  Inc.,  Barron's,  IBC/Donoghue's  Money Fund
Report(,  The Wall Street  Journal and The New York Times;  reports  prepared by
Lipper  Analytical  Services,  Inc.;  and  publications  of a local or  regional
nature.

         A  Fund's  yield  figures  for  a  class  of  shares   represent   past
performance,  will fluctuate and should not be considered as  representative  of
future results. The yield of any investment is generally a function of portfolio
quality and  maturity,  type of  investment  and  operating  expenses.  Any fees
charged by Service  Organizations or other  institutional  investors directly to
their customers in connection with  investments in Fund shares are not reflected
in a Fund's  expenses or yields;  and, such fees,  if charged,  would reduce the
actual return  received by customers on their  investments.  The methods used to
compute  a Fund's  yields  are  described  in more  detail in the  Statement  of
Additional  Information.  Investors may call  1-800-238-2560  to obtain  current
yield information.

                     DESCRIPTION OF SHARES AND MISCELLANEOUS

         The Trust is a Massachusetts business trust established on November 25,
1992. The Trust's Declaration of Trust authorizes the Board of Trustees to issue
an unlimited number of full and fractional shares of beneficial  interest in the
Trust  and to  classify  or  reclassify  any  unissued  shares  into one or more
additional  classes of shares.  The Trust is an open-end  management  investment
company,  which currently  offers ten  portfolios.  The Trust has authorized the
issuance  of seven  classes  of  shares  for  Prime  Value  Money  Market  Fund,
Government  Obligations  Money Market Fund and  Municipal  Money Market Fund and
four  classes of shares for Prime  Money  Market  Fund,  Cash  Management  Fund,
Treasury  Instruments  Money Market Fund II and Tax-Free  Money Market Fund. The
issuance  of separate  classes of shares is  intended  to address the  different
service needs of different types of investors.  The Declaration of Trust further
authorizes  the Trustees to classify or reclassify  any class of shares into one
or more sub-classes.

         The  Trust  does  not  presently  intend  to hold  annual  meetings  of
shareholders  except as required by the 1940 Act or other  applicable  law.  The
Trust will call a meeting of  shareholders  for the  purpose of voting  upon the
question of removal of a member of the Board of Trustees upon written request of
shareholders owning at least 10% of the outstanding shares of the Trust entitled
to vote.

         Each Fund share  represents  an equal,  proportionate  interest  in the
assets belonging to the Fund. Each share, which has a par value of $.001, has no
preemptive  or conversion  rights.  When issued for payment as described in this
Prospectus, Fund shares will be fully paid and non-assessable.

         Holders  of the Fund's  shares  will vote in the  aggregate  and not by
class on all matters, except where otherwise required by law and except when the
Board of Trustees  determines  that the matter to be voted upon affects only the
shareholders of a particular class. Further, shareholders of the Funds will vote
in the  aggregate  and not by portfolio  except as otherwise  required by law or
when the Board of Trustees  determines  that the matter to be voted upon affects
only the  interests  of the  shareholders  of a  particular  portfolio  (see the
Statement of Additional  Information  under "Additional  Description  Concerning
Fund Shares" for  examples  where the 1940 Act  requires  voting by  portfolio).
Shareholders  of the Trust are  entitled  to one vote for each full  share  held
(irrespective of class or portfolio) and fractional votes for fractional  shares
held. Voting rights are not cumulative;  and,  accordingly,  the holders of more
than 50% of the aggregate shares of the Trust may elect all of the trustees.

         For  information  concerning the redemption of Fund shares and possible
restrictions on their transferability, see "Purchase and Redemption of Shares."

                        SUMMARY OF INVESTMENT OBJECTIVES

         The  investment  objectives  of the Funds  are  summarized  below.  See
"Investment  Objectives  and  Policies"  beginning  on page 6 for more  detailed
information.


         PRIME MONEY MARKET FUND seeks to provide  current  income and stability
of principal by investing in a broad range of short-term instruments,  including
U.S.  Government  and  U.S.  bank  and  commercial  obligations  and  repurchase
agreements relating to such obligations.


         PRIME  VALUE  MONEY  MARKET  FUND seeks to provide  current  income and
stability of principal by investing in a portfolio  consisting  of a broad range
of  short-term  instruments,   including  U.S.  Government  and  U.S.  bank  and
commercial  obligations and repurchase  agreements relating to such obligations.
Under normal market conditions,  at least 25% of the Fund's total assets will be
invested  in  obligations  of issuers in the  banking  industry  and  repurchase
agreements relating to such obligations.


         GOVERNMENT  OBLIGATIONS  MONEY  MARKET  FUND seeks to  provide  current
income with  liquidity  and  security of  principal  by investing in a portfolio
consisting  of U.S.  Treasury  bills,  notes  and  other  obligations  issued or
guaranteed  by the  U.S.  Government,  its  agencies  or  instrumentalities  and
repurchase agreements relating to such obligations.


         TREASURY  INSTRUMENTS  MONEY  MARKET  FUND II seeks to provide  current
income with  liquidity  and  security of  principal  by investing in a portfolio
consisting of U.S. Treasury bills, notes and direct obligations of the U.S.
Treasury and repurchase agreements relating to direct Treasury obligations.


         TAX-FREE  MONEY MARKET FUND seeks to provide as high a level of current
income exempt from federal taxation as is consistent with relative  stability of
principal  by  investing  in a portfolio  consisting  of  short-term  tax-exempt
obligations   issued  by  state  and  local  governments  and  other  tax-exempt
securities which are considered  "First Tier Eligible  Securities" as defined in
"Investment  Objectives and Policies." The Fund will not purchase securities the
income from which may be a specific tax preference  item for purposes of federal
individual and corporate alternative minimum tax.


         MUNICIPAL MONEY MARKET FUND seeks to provide as high a level of current
income exempt from federal taxation as is consistent with relative  stability of
principal  by  investing  in a portfolio  consisting  of  short-term  tax-exempt
obligations   issued  by  state  and  local  governments  and  other  tax-exempt
securities which are considered "Eligible  Securities" as defined in "Investment
Objectives and Policies."


         There is no  assurance  that the Funds will  achieve  their  respective
investment objectives.

                       BACKGROUND AND EXPENSE INFORMATION

         Each Fund currently  offers four classes of shares,  only one of which,
Class E Shares,  is offered by this Prospectus.  Each class represents an equal,
pro rata interest in a Fund.  Each Fund's other classes of shares have different
service  and/or  distribution  fees and expenses from Class E Shares which would
affect  the  performance  of those  classes  of  shares.  Investors  may  obtain
information  concerning  the Funds'  other  classes of shares by calling  Lehman
Brothers at 1-800-568-5556.

         The  purpose  of the  following  table  is to  assist  an  investor  in
understanding  the various  costs and  estimated  expenses that an investor in a
Fund would bear directly or  indirectly.  Certain  institutions  may also charge
their clients fees in connection with investments in Class E Shares,  which fees
are not  reflected in the table below.  For more  complete  descriptions  of the
various costs and expenses, see "Management of the Funds" in this Prospectus and
the Statement of Additional Information.

*The Expense  Summary above has been restated to reflect  current  expected fees
and  the  Adviser's  and  Administrator's   voluntary  fee  waiver  and  expense
reimbursement arrangements currently in effect.

         In order to  maintain a  competitive  expense  ratio,  the  Adviser and
Administrator  have voluntarily  agreed to waive fees and reimburse  expenses to
the extent  necessary  to maintain  an  annualized  expense  ratio at a level no
greater than .33% of average daily net assets (.18%  excluding  Rule 12b-1 fees)
with respect to the Funds.  The voluntary  fee waiver and expense  reimbursement
arrangements  described  above  will  not be  changed  unless  shareholders  are
provided at least 60 days' advance notice.  The maximum annual  contractual fees
payable to the Adviser and Administrator  total .30% of average daily net assets
of the Funds.  Absent fee  waivers and  expense  reimbursements,  the Total Fund
Operating Expenses of Class E Shares are expected to be as follows:

                       INVESTMENT OBJECTIVES AND POLICIES

         The  investment  objectives  and  general  policies  of each  Fund  are
described  below.  Specific  investment  techniques  that may be employed by the
Funds are described in a separate  section of this  Prospectus.  See  "Portfolio
Instruments  and  Practices."  Differences  in objectives and policies among the
Funds,  differences in the degree of acceptable risk and tax  considerations are
some of the factors that can be expected to affect the investment return of each
Fund. Because of such factors,  the performance  results of the Funds may differ
even though more than one Fund may utilize the same security selections.

         Unless  otherwise  stated,  the investment  objectives and policies set
forth in this  Prospectus are not fundamental and may be changed by the Board of
Trustees without  shareholder  approval.  If there is a change in

                                       6

<PAGE>

the investment objective and policies of any Fund,  shareholders should consider
whether  the  Fund  remains  an   appropriate   investment  in  light  of  their
then-current   financial  position  and  needs.  The  market  value  of  certain
fixed-rate  obligations  held by the Funds will  generally  vary  inversely with
changes in market  interest rates.  Thus, the market value of these  obligations
generally  declines when interest  rates rise and generally  rises when interest
rates  decline.  The Funds are subject to  additional  investment  policies  and
restrictions described in the Statement of Additional Information, some of which
are fundamental and may not be changed without shareholder approval.

         The  Funds  seek to  maintain  a net asset  value of $1.00  per  share,
although  there is no assurance  that they will be able to do so on a continuing
basis.  Each  Fund  operates  as a  diversified  investment  portfolio.  Certain
securities  held by the Funds may have remaining  maturities in excess of stated
limitations  discussed  below if  securities  provide for  adjustments  in their
interest  rates  not less  frequently  than  such  time  limitations.  Each Fund
maintains a dollar-weighted average portfolio maturity of 90 days or less.

         PRIME  MONEY  MARKET  FUND AND PRIME  VALUE  MONEY  MARKET FUND seek to
provide current income and stability of principal.  In pursuing their investment
objectives,  the  Funds  invest  in a broad  range  of  short-term  instruments,
including  U.S.  Government  and  U.S.  bank  and  commercial   obligations  and
repurchase  agreements  relating to such  obligations.  Prime Value Money Market
Fund may also invest in securities of foreign issuers. Each Fund invests only in
securities  that are  payable in U.S.  dollars  and that have (or,  pursuant  to
regulations  adopted by the SEC will be deemed to have) remaining  maturities of
thirteen months or less at the date of purchase by the Fund.

         Both  Funds  invest  in  securities  rated by the  "Requisite  NRSROs."
"Requisite  NRSROs" means (a) any two  nationally-recognized  statistical rating
organizations ("NRSROs") that have issued a rating with respect to a security or
class of debt obligations of an issuer,  or (b) one NRSRO, if only one NRSRO has
issued such a rating at the time that the Fund acquires the security. Currently,
there are six NRSROs: Standard & Poor's, a division of The McGraw-Hill Companies
("S&P"); Moody's Investors Service, Inc. ("Moody's");  Fitch Investors Services,
Inc.;  Duff and Phelps,  Inc.;  IBCA Limited and its affiliate,  IBCA,  Inc. and
Thomson  Bankwatch.  A  discussion  of the ratings  categories  of the NRSROs is
contained in the Appendix to the Statement of Additional Information.

         Prime  Money  Market  Fund will  limit  its  portfolio  investments  to
securities  that the Board of Trustees  determines  present minimal credit risks
and which are "First Tier Eligible Securities" at the time of acquisition by the
Fund. The term First Tier Eligible  Securities  includes securities rated by the
Requisite  NRSROs in the highest  short-term  rating  categories,  securities of
issuers that have  received  such rating with respect to other  short-term  debt
securities and comparable unrated securities.

         Prime Value Money Market Fund will limit its portfolio  investments  to
securities  that the Board of Trustees  determines  present minimal credit risks
and which are "Eligible  Securities" at the time of acquisition by the Fund. The
term Eligible  Securities  includes  securities rated by the Requisite NRSROs in
one of the two highest short-term rating categories,  securities of issuers that
have received such ratings with respect to other  short-term debt securities and
comparable unrated securities.

         Each Fund  generally may not invest more than 5% of its total assets in
the  securities of any one issuer,  except for U.S.  Government  securities.  In
addition, Prime Value Money Market Fund may not invest more than 5% of its total
assets in Eligible Securities that have not received the highest rating from the
Requisite NRSROs and comparable  unrated  securities  ("Second Tier Securities")
and may  not  invest  more  than  1% of its  total  assets  in the  Second  Tier
Securities  of any one  issuer.  The Funds may invest  more than 5% (but no more
than 25%) of the then-current value of the Fund's total assets in the securities
of a single issuer for a period of up to three business days,  provided that (a)
the  securities  either  are  rated  by the  Requisite  NRSROs  in  the  highest
short-term  rating category or are securities of issuers that have received such
rating  with  respect to other  short-term  debt  securities  or are  comparable
unrated securities, and (b) the Fund does not make more than one such investment
at any one time.

         Each Fund may purchase  obligations of issuers in the banking industry,
such as commercial paper,  notes,  certificates of deposit,  bankers acceptances
and time deposits and U.S. dollar denominated instruments issued or supported by
the credit of U.S.  (or foreign in the case of Prime Value  Money  Market  Fund)
banks or savings  institutions  having  total  assets at the time of purchase in
excess of $1 billion. The Funds may also make interest-bearing  savings deposits
in commercial and savings banks in amounts not in excess of 5% of their assets.

         GOVERNMENT OBLIGATIONS MONEY MARKET FUND AND TREASURY INSTRUMENTS MONEY
MARKET FUND II seek to provide  income with liquidity and security of principal.
Each Fund invests only in securities  that are payable in U.S.  dollars and that
have (or,  pursuant to  regulations  adopted by the SEC, will be deemed to have)
remaining  maturities of thirteen  months or less at the date of purchase by the
Fund (twelve months in the case of Government Obligations Money Market Fund).

         Government  Obligations Money Market Fund invests in obligations issued
or  guaranteed by the U.S.  Government,  its agencies or  instrumentalities  (in
addition to direct Treasury  obligations) and repurchase  agreements relating to
such obligations.

         Treasury  Instruments  Money  Market  Fund II invests  solely in direct
obligations  of the U.S.  Treasury,  such as  Treasury  bills and notes,  and in
repurchase agreements relating to direct Treasury obligations. The Fund will not
purchase obligations of agencies or instrumentalities of the U.S. Government.

         TAX-FREE  MONEY  MARKET FUND AND  MUNICIPAL  MONEY  MARKET FUND seek to
provide  investors  with as high a level of current  income  exempt from federal
income tax as is consistent  with relative  stability of principal.  In pursuing
their investment objectives,  the Funds invest substantially all of their assets
in diversified  portfolios of short-term tax-exempt  obligations issued by or on
behalf of states, territories and possessions of the United States, the District
of Columbia, and their respective authorities,  agencies,  instrumentalities and
political  subdivisions  and  tax-exempt  derivative  securities  such as tender
option bonds,  participations,  beneficial  interests in trusts and  partnership
interests  (collectively  "Municipal  Obligations").  Each Fund  invests only in
securities  that have (or,  pursuant to regulations  adopted by the SEC, will be
deemed to have)  remaining  maturities of thirteen months or less at the date of
purchase  by the Fund.  The Funds will not  knowingly  purchase  securities  the
interest on which is subject to federal  income  tax.  Except  during  temporary
defensive periods, each Fund will invest substantially all, but in no event less
than 80%, of its net assets in Municipal Obligations. Tax-Free Money Market Fund
will not invest its assets in securities the income from which may be a specific
tax preference item for purposes of federal individual and corporate alternative
minimum  tax.  The  Funds  also  have  the  ability  to  enter  into  repurchase
agreements.  Absent emergency or extraordinary  circumstances,  however, neither
Fund  presently  intends  to  engage in  repurchase  transactions,  unless  such
transactions would not generate taxable income to such Funds.

         Both the  Tax-Free  Money Market Fund and  Municipal  Money Market Fund
purchase Municipal Obligations that present minimal credit risk as determined by
the  Adviser  pursuant to  guidelines  approved  by the Board of  Trustees.  The
Municipal  Money Market Fund invests in Eligible  Securities  while the Tax-Free
Money Market Fund invests in only First Tier Eligible Securities.  The Funds may
hold uninvested cash reserves pending  investment or during temporary  defensive
periods,  including when suitable tax-exempt obligations are unavailable.  There
is no  percentage  limitation  on  the  amount  of  assets  which  may  be  held
uninvested. Uninvested cash reserves will not earn income.

         Although the Tax-Free Money Market Fund may invest more than 25% of its
net assets in (a) Municipal  Obligations whose issuers are in the same state and
(b) Municipal  Obligations the interest on which is paid solely from revenues of
similar  projects,  it does not presently intend to do so on a regular basis. To
the extent the Fund's assets are concentrated in Municipal  Obligations that are
payable from the revenues of similar  projects or are issued by issuers  located
in the same state,  the Fund will be subject to the peculiar risks  presented by
the laws and economic conditions relating to such states,  projects and bonds to
a greater extent than it would be if its assets were not so concentrated.

                       PORTFOLIO INSTRUMENTS AND PRACTICES

         Investment  strategies  that are  available  to the Funds are set forth
below.  Additional  information concerning certain of these strategies and their
related risks is contained in the Statement of Additional Information.

U.S. GOVERNMENT OBLIGATIONS

         Each Fund (other than Tax-Free  Money Market Fund and  Municipal  Money
Market  Fund)  may  purchase  obligations  issued  or  guaranteed  by  the  U.S.
Government and (except in the case of Treasury Instruments Money Market Fund II)
U.S. Government agencies and instrumentalities.  Securities issued or guaranteed
by the  U.S.  Government  or its  agencies  or  instrumentalities  include  U.S.
Treasury  securities,  which differ in interest  rates,  maturities and times of
issuance.  Treasury bills have initial maturities of one year or less;  Treasury
notes have initial  maturities of one to ten years; and Treasury bonds generally
have initial  maturities of greater than ten years.  Some obligations  issued or
guaranteed  by U.S.  Government  agencies  or  instrumentalities,  for  example,
Government  National  Mortgage  Association   pass-through   certificates,   are
supported  by the full faith and credit of the U.S.  Treasury;  others,  such as
those issued by the Federal  National  Mortgage  Association,  by  discretionary
authority of the U.S.  Government to purchase certain  obligations of the agency
or  instrumentality;  and  others,  such as those  issued  by the  Student  Loan
Marketing  Association,  only by the  credit of the  agency or  instrumentality.
These securities bear fixed,  floating or variable rates of interest.  While the
U.S.  Government  provides  financial support to such U.S.  Government-sponsored
agencies or instrumentalities,  no assurance can be given that it will always do
so,  since  it is not so  obligated  by  law.  The  Funds  will  invest  in such
securities only when they are satisfied that the credit risk with respect to the
issuer is minimal.

         Securities issued or guaranteed by the U.S. Government, its agencies or
instrumentalities have historically involved little risk of loss of principal if
held to maturity.  However,  due to fluctuations  in interest rates,  the market
value of the  securities may vary during the period an investor owns shares of a
Fund.

REPURCHASE AGREEMENTS

         The Funds may agree to purchase securities from financial  institutions
subject to the seller's  agreement to repurchase them at an agreed upon time and
price within one year from the date of  acquisition  ("repurchase  agreements").
The Funds  will not  invest  more  than 10% of the value of their net  assets in
repurchase  agreements  with terms which exceed  seven days.  The seller under a
repurchase  agreement  will be required to maintain the value of the  securities
subject  to the  agreement  at not less  than the  repurchase  price  (including
accrued interest). Default by or bankruptcy of the seller would, however, expose
the  Funds to  possible  loss  because  of  adverse  market  action  or delay in
connection with the disposition of the underlying obligations.

REVERSE REPURCHASE AGREEMENTS

         Each Fund may borrow  funds for  temporary  purposes by  entering  into
reverse  repurchase  agreements in accordance  with the investment  restrictions
described  below.  Pursuant to such  agreements,  the Funds would sell portfolio
securities to financial  institutions  and agree to repurchase them at an agreed
upon date and price. The Funds would consider  entering into reverse  repurchase
agreements to avoid  otherwise  selling  securities  during  unfavorable  market
conditions. Reverse repurchase agreements involve the risk that the market value
of the  securities  sold  by the  Funds  may  decline  below  the  price  of the
securities  the Funds  are  obligated  to  repurchase.  The Funds may  engage in
reverse repurchase agreements provided that the amount of the reverse repurchase
agreements and any other  borrowings  does not exceed  one-third of the value of
the Fund's total assets (including the amount borrowed) less liabilities  (other
than borrowings).

WHEN-ISSUED SECURITIES

         The Funds (other than Tax-Free  Money Market Fund and  Municipal  Money
Market Fund) may  purchase  securities  on a  "when-issued"  basis.  When-issued
securities are securities  purchased for delivery  beyond the normal  settlement
date at a stated  price and  yield.  The Funds will  generally  not pay for such
securities or start earning interest on them until they are received. Securities
purchased  on a  when-issued  basis are  recorded as an asset and are subject to
changes in value based upon changes in the general level of interest rates.  The
Funds expect that commitments to purchase when-issued securities will not exceed
25% of the value of their total assets absent  unusual  market  conditions.  The
Funds do not intend to purchase when-issued  securities for speculative purposes
but only in furtherance of their investment objectives.

ILLIQUID SECURITIES

         Prime Money Market Fund, Prime Value Money Market Fund,  Tax-Free Money
Market Fund and Municipal Money Market Fund will not knowingly  invest more than
10% of the value of their  total net assets in  illiquid  securities,  including
time deposits and  repurchase  agreements  having  maturities  longer than seven
days.  Securities that have readily  available market  quotations are not deemed
illiquid  for  purposes  of  this  limitation  (irrespective  of  any  legal  or
contractual  restrictions on resale). Each of the Funds may invest in commercial
obligations  issued in reliance on the so-called "private  placement"  exemption
from  registration  afforded by Section 4(2) of the  Securities  Act of 1933, as
amended ("Section 4(2) paper").  Each of the Funds may also purchase  securities
that are not registered under the Securities Act of 1933, as amended,  but which
can be sold to qualified institutional buyers in accordance with Rule 144A under
that Act  ("Rule  144A  securities").  Section  4(2) paper is  restricted  as to
disposition  under  the  federal  securities  laws,  and  generally  is  sold to
institutional investors such as the Funds who agree that they are purchasing the
paper for investment and not with a view to public  distribution.  Any resale by
the purchaser must be in an exempt  transaction.  Section 4(2) paper is normally
resold  to other  institutional  investors  like the  Fund  through  or with the
assistance of the issuer or investment  dealers who make a market in the Section
4(2) paper,  thus providing  liquidity.  Rule 144A securities  generally must be
sold to other  qualified  institutional  buyers.  If a particular  investment in
Section 4(2) paper or Rule 144A securities is not determined to be liquid,  that
investment  will be included  within the percentage  limitation on investment in
illiquid securities.

FOREIGN SECURITIES

         Prime Value Money Market Fund may invest substantially in securities of
foreign issuers,  including  obligations of foreign banks or foreign branches of
U.S. banks, and debt securities of foreign issuers,  where the Adviser deems the
instrument  to present  minimal  credit risks.  Investments  in foreign banks or
foreign  issuers   present   certain  risks,   including  those  resulting  from
fluctuations  in currency  exchange  rates,  revaluation of  currencies,  future
political  and economic  developments  and the possible  imposition  of currency
exchange  blockages  or other  foreign  governmental  laws or  restrictions  and
reduced  availability of public  information.  Foreign issuers are not generally
subject to uniform accounting,  auditing and financial reporting standards or to
other regulatory practices and requirements applicable to domestic issuers.

ZERO COUPON AND CAPITAL APPRECIATION BONDS

         The Funds may invest in zero  coupon and  capital  appreciation  bonds,
which are debt securities issued or sold at a discount from their face value and
which do not entitle  the holder to any  periodic  payment of interest  prior to
maturity or a specified  redemption  date (or cash payment date).  The amount of
the discount  varies  depending  on the time  remaining  until  maturity or cash
payment date,  prevailing  interest rates, the liquidity of the security and the
perceived credit quality of the issuer.  These securities may also take the form
of debt securities that have been stripped of their unmatured  interest coupons,
the coupons themselves or receipts or certificates representing interest in such
stripped  debt  obligations  or  coupons.  Discounts  with  respect to  stripped
tax-exempt  securities  or their  coupons may be taxable.  The market  prices of
capital appreciation bonds generally are more volatile than the market prices of
interest-bearing  securities  and are likely to  respond to a greater  degree to
changes  in  interest  rates than  interest-bearing  securities  having  similar
maturity and credit quality.

U.S. TREASURY STRIPS

         The Prime Money Market Fund, Prime Value Money Market Fund,  Government
Obligations Money Market Fund and Treasury  Instruments Money Market Fund II may
invest in  separately  traded  principal  and interest  components of securities
backed by the full  faith and credit of the U.S.  Treasury.  The  principal  and
interest  components of U.S. Treasury bonds with remaining  maturities of longer
than ten  years  are  eligible  to be traded  independently  under the  Separate
Trading of Registered  Interest and Principal of Securities  ("STRIPS") program.
Under the STRIPS program,  the principal and interest  components are separately
issued by the U.S. Treasury at the request of depository financial institutions,
which then trade the component parts  separately.  Under the stripped bond rules
of the Internal  Revenue Code of 1986, as amended (the "Code"),  investments  by
the Funds in  STRIPS  will  result in the  accrual  of  interest  income on such
investments in advance of the receipt of the cash  corresponding to such income.
The interest component of STRIPS may be more volatile than that of U.S. Treasury
bills with  comparable  maturities.  In  accordance  with Rule 2a-7,  the Funds'
investment in STRIPS are limited to those with maturity components not exceeding
thirteen months.

LENDING OF PORTFOLIO SECURITIES

         Each Fund may lend portfolio securities up to one-third of the value of
its total assets to broker/dealers,  banks or other  institutional  borrowers of
securities  that the Adviser has determined are  creditworthy  under  guidelines
established by the Board of Trustees.  The Funds will receive  collateral in the
form of cash,  letters of credit,  or securities  of the U.S.  Government or its
agencies equal to at least 100% of the value of the securities owned.

VARIABLE AND FLOATING RATE SECURITIES

         The interest  rates payable on certain  securities in which Prime Money
Market Fund, Prime Value Money Market Fund, Government  Obligations Money Market
Fund,  Tax-Free Money Market Fund and Municipal Money Market Fund may invest are
not fixed and may fluctuate  based upon changes in market rates. A variable rate
obligation  has an interest  rate which is adjusted  at  predesignated  periods.
Interest on a floating rate obligation is adjusted whenever there is a change in
the  market  rate of  interest  on which the  interest  rate  payable  is based.
Tax-exempt variable or floating rate obligations generally permit the holders of
such obligations to demand payment of principal from the issuer or a third party
at stated  intervals.  Variable and floating rate obligations are less effective
than fixed rate instruments at locking in a particular  yield.  Such obligations
may  fluctuate in value in response to interest rate changes if there is a delay
between  changes in market  interest  rates and the interest  reset date for the
obligation.  The Funds will take demand or reset features into  consideration in
determining  the  average  portfolio  duration  of the  Fund  and the  effective
maturity of individual securities.  In addition, the absence of an unconditional
demand feature  exercisable within seven days will require a tax-exempt variable
or floating  rate  obligation to be treated as illiquid for purposes of a Fund's
limitation on illiquid  investments.  The failure of the issuer or a third party
to honor its  obligations  under a demand or put  feature  might also  require a
tax-exempt  variable or floating  rate  obligation to be treated as illiquid for
purposes of a Fund's limitation on illiquid investments.

TAX-EXEMPT COMMERCIAL PAPER

         Tax-Free  Money Market Fund and Municipal  Money Market Fund may invest
in tax-exempt  commercial paper.  Issues of commercial paper typically represent
short-term, unsecured, negotiable promissory notes. These obligations are issued
by state and local  governments  and their agencies to finance  working  capital
needs of  municipalities  or to provide interim  construction  financing and are
paid from general or specific revenues of municipalities or are re-financed with
long-term debt. In some cases,  tax-exempt commercial paper is backed by letters
of credit,  lending  agreements,  note  repurchase  agreements  or other  credit
facility  arrangements  offered by banks or other  institutions.  The Funds will
invest only in tax-exempt  commercial paper rated at least Prime-2 by Moody's or
A-2 by S&P.

MUNICIPAL OBLIGATIONS

         Tax-Free  Money Market Fund and Municipal  Money Market Fund may invest
in the Municipal Obligations described below.

         Municipal  Obligations.  Municipal Obligations include bonds, notes and
other instruments issued by or on behalf of states,  territories and possessions
of the United States  (including  the District of Columbia) and their  political
subdivisions,  agencies or  instrumentalities,  the interest on which is, in the
opinion of bond counsel,  exempt from regular federal income tax (i.e., excluded
from gross income for federal  income tax purposes  but not  necessarily  exempt
from the personal  income  taxes of any state or, with respect to the  Municipal
Money Market  Fund,  from the federal  alternative  minimum  tax).  In addition,
Municipal  Obligations  include  participation  interests in such securities the
interest on which is, in the opinion of bond  counsel for the issuers or counsel
selected by the Adviser,  exempt from regular federal income tax. The definition
of Municipal Obligations includes other types of securities that currently exist
or may be  developed  in the future and that are,  or will be, in the opinion of
counsel,  as described above,  exempt from regular federal income tax,  provided
that  investing  in such  securities  is  consistent  with a  Fund's  investment
objective and policies.

         The two principal classifications of Municipal Obligations which may be
held by the Funds are "general obligation"  securities and "revenue" securities.
General  obligation  securities  are secured by the issuer's  pledge of its full
faith,  credit  and taxing  power for the  payment of  principal  and  interest.
Revenue  securities are payable only from the revenues derived from a particular
facility  or class of  facilities,  or in some  cases,  from the  proceeds  of a
special  excise tax or other  specific  revenue  source  such as the user of the
facility being financed. Revenue securities include private activity bonds which
may be held by the  Municipal  Money  Market Fund and which are not payable from
the unrestricted  revenues of the issuer.  While some private activity bonds are
general  obligation  securities,  the  vast  majority  are  revenue  securities.
Consequently,  the credit quality of private  activity bonds is usually directly
related to the credit  standing of the corporate user of the facility  involved.
Each of the Municipal  Obligations  described  below may take the form of either
general obligation or revenue securities.

         Municipal  Obligations  are often  issued to obtain  funds for  various
public purposes, including the construction of a wide range of public facilities
such as bridges,  highways,  housing,  hospitals, mass transportation,  schools,
streets and water and sewer  works.  Other public  purposes for which  Municipal
Obligations may be issued include refunding outstanding  obligations,  obtaining
funds for  general  operating  expenses,  and  obtaining  funds to lend to other
public   institutions  and  facilities.   Municipal   Obligations  also  include
industrial  development  bonds,  or with respect to the  Municipal  Money Market
Fund,  private  activity  bonds,  which  are  issued  by or on  behalf of public
authorities to obtain funds for privately-operated housing facilities,  airport,
mass  transit or port  facilities,  sewage  disposal,  solid  waste  disposal or
hazardous  waste treatment or disposal  facilities and certain local  facilities
for  water  supply,  gas  or  electricity.  In  addition,  proceeds  of  certain
industrial development bonds are used for the construction, equipment, repair or
improvement  of privately  operated  industrial  or commercial  facilities.  The
interest income from private activity bonds may subject certain investors to the
federal alternative minimum tax.

         Municipal Leases, Certificates of Participation and Other Participation
Interests.  The Funds  may  invest  in  municipal  leases  and  certificates  of
participation  in municipal  leases.  A municipal  lease is an obligation in the
form of a lease or  installment  purchase  which is  issued  by a state or local
government to acquire equipment and facilities.  Income from such obligations is
generally exempt from state and local taxes in the state of issuance.  Municipal
leases  frequently  involve  special risks not normally  associated with general
obligation or revenue bonds. Leases and installment purchase or conditional sale
contracts  (which  normally  provide  for  title  to the  leased  asset  to pass
eventually to the governmental  issuer) have evolved as a means for governmental
issuers to acquire property and equipment without meeting the constitutional and
statutory  requirements for the issuance of debt. The debt issuance  limitations
are  deemed  to be  inapplicable  because  of the  inclusion  in many  leases or
contracts of "non-appropriation" clauses that relieve the governmental issuer of
any obligation to make future  payments under the lease or contract unless money
is appropriated for such purpose by the appropriate legislative body on a yearly
or other periodic basis. In addition, such leases or contracts may be subject to
the  temporary  abatement of payments in the event the issuer is prevented  from
maintaining  occupancy of the leased premises or utilizing the leased equipment.
Although the  obligation  may be secured by the leased  equipment or facilities,
the disposition of the property in the event of  nonappropriation or foreclosure
might  prove   difficult,   time   consuming  and  costly,   and  result  in  an
unsatisfactory or delayed recoupment of the Fund's original investment.

                                       12
  

<PAGE>

       Certificates  of  participation   represent   undivided   interests  in
municipal leases,  installment  purchase  agreements or other  instruments.  The
certificates  are typically issued by a trust or other entity which has received
an assignment  of the payments to be made by the state or political  subdivision
under such leases or installment purchase agreements.

         Certain  municipal lease  obligations and certificates of participation
may be deemed illiquid for the purpose of a Fund's  limitation on investments in
illiquid  securities.  Other  municipal lease  obligations  and  certificates of
participation  acquired by the Funds may be determined by the Adviser,  pursuant
to guidelines adopted by the Board of Trustees,  to be liquid securities for the
purpose of such  limitation.  In  determining  the liquidity of municipal  lease
obligations  and  certificates  of  participation,  the Adviser will  consider a
variety  of  factors  including  (a) the  willingness  of dealers to bid for the
security,  (b) the number of dealers  willing to purchase or sell the obligation
and the number of other potential buyers,  (c) the frequency of trades or quotes
for the obligation,  and (d) the nature of marketplace trades. In addition,  the
Adviser  will  consider  factors  unique to  particular  lease  obligations  and
certificates of participation affecting the marketability thereof. These include
the general  creditworthiness  of the issuer,  the  importance  of the  property
covered by the lease to the issuer and the likelihood that the  marketability of
the obligation will be maintained  throughout the time the obligation is held by
the Funds.

         The Funds may also  purchase  participations  in Municipal  Obligations
held by a commercial bank or other financial  institution.  Such  participations
provide  the  Funds  with  the  right to a pro rata  undivided  interest  in the
underlying Municipal  Obligations.  In addition,  such participations  generally
provide the Funds with the right to demand payment,  on not more than seven days
notice, of all or any part of a Fund's participation  interest in the underlying
Municipal Obligation, plus accrued interest. These demand features will be taken
into consideration in determining the effective maturity of such  participations
and the average  portfolio  duration of the Funds. The Funds will only invest in
such  participations  if, in the  opinion  of bond  counsel  for the  issuers or
counsel selected by the Adviser, the interest from such participations is exempt
from regular federal income tax.

         Municipal  Notes.  Municipal  Obligations  purchased  by the  Funds may
include  fixed-rate notes or variable-rate  demand notes.  Such notes may not be
rated by credit rating  agencies,  but unrated notes purchased by the Funds will
be determined by the Adviser to be of comparable quality at the time of purchase
to rated instruments purchasable by the Funds. Where necessary to determine that
a note is an Eligible Security or First Tier Eligible  Security,  the Funds will
require the issuer's obligation to pay the principal of the note be backed by an
unconditional  bank letter or line of credit,  guarantee or  commitment to lend.
While  there may be no active  secondary  market  with  respect to a  particular
variable  rate demand note  purchased by the Funds,  the Funds may,  upon notice
specified in the note,  demand  payment of the principal of the note at any time
or during specified  periods not exceeding  thirteen months,  depending upon the
instrument  involved,  and may resell the note at any time to a third party. The
absence of such an active secondary market, however, could make it difficult for
the Funds to dispose  of a  variable  rate  demand  note if the  issuer  were to
default  on its  payment  obligation  or during  periods  that the Funds are not
entitled to exercise their demand rights, and the Funds could, for this or other
reasons, suffer losses to the extent of the default.

         Pre-Refunded   Municipal   Obligations.   The  Funds   may   invest  in
pre-refunded   Municipal   Obligations.   The   principal  of  and  interest  on
pre-refunded  Municipal Obligations are no longer paid from the original revenue
source for the Municipal  Obligations.  Instead,  the source of such payments is
typically an escrow fund  consisting of obligations  issued or guaranteed by the
U.S. Government.  The assets in the escrow fund are derived from the proceeds of
refunding  bonds  issued  by  the  same  issuer  as the  pre-refunded  Municipal
Obligations,  but  usually on terms more  favorable  to the  issuer.  Issuers of
Municipal  Obligations  use this  advance  refunding  technique  to obtain  more
favorable terms with respect to Municipal  Obligations which are not yet subject
to call or redemption by the issuer.  For example,  advance refunding enables an
issuer to refinance debt at lower market  interest  rates,  restructure  debt to
improve cash flow or eliminate  restrictive  covenants in the indenture or other
governing instrument for the pre-refunded Municipal Obligations. However, except
for a change in the revenue  source from which  principal and interest  payments
are made, the pre-refunded  Municipal  Obligations  remain  outstanding on their
original  terms until they mature or are redeemed by the issuer.  The  effective
maturity of pre-refunded  Municipal  Obligations  will be the redemption date if
the issuer has assumed an  obligation  or indicated its intention


                                       13

<PAGE>

to redeem  such  obligations  on the  redemption  date.  Pre-refunded  Municipal
Obligations are often purchased at a price which represents a premium over their
face value.

         Tender Option  Bonds.  The Funds may purchase  tender  option bonds.  A
tender  option  bond is a Municipal  Obligation  (generally  held  pursuant to a
custodial arrangement) having a relatively long maturity and bearing interest at
a fixed rate substantially higher than prevailing  short-term  tax-exempt rates,
that has been  coupled  with the  agreement  of a third  party,  such as a bank,
broker-dealer or other financial institution, pursuant to which such institution
grants the security holders the option, at periodic  intervals,  to tender their
securities  to  the  institution   and  receive  the  face  value  thereof.   As
consideration  for providing  the option,  the  financial  institution  receives
periodic fees equal to the difference  between the Municipal  Obligation's fixed
coupon rate and the rate, as determined by a remarketing  or similar agent at or
near the commencement of such period,  that would cause the securities,  coupled
with  the  tender  option,  to  trade  at or  near  par  on  the  date  of  such
determination.  Thus, after payment of this fee, the security holder effectively
holds a demand  obligation  that bears  interest  at the  prevailing  short-term
tax-exempt   rate.   The  Adviser  will   consider  on  an  ongoing   basis  the
creditworthiness of the issuer of the underlying  Municipal  Obligation,  of any
custodian  and of the third  party  provider  of the tender  option.  In certain
instances and for certain  tender option bonds,  the option may be terminable in
the event of a default in payment of  principal  or interest  on the  underlying
Municipal Obligations and for other reasons. Additionally, the above description
of tender  option  bonds is meant only to  provide  an  example of one  possible
structure of such  obligations,  and the Funds may purchase  tender option bonds
with   different   types  of  ownership,   payment,   credit  and/or   liquidity
arrangements.

                             INVESTMENT LIMITATIONS

         The Funds' investment  objectives and policies  described above are not
fundamental  and may be  changed  by the  Board of  Trustees  without  a vote of
shareholders.  If there  is a  change  in the  investment  objective  of a Fund,
shareholders should consider whether the Fund remains an appropriate  investment
in light of  their  then  current  financial  position  and  needs.  The  Funds'
investment   limitations   described  below  may  not  be  changed  without  the
affirmative vote of the holders of a majority of its outstanding  shares.  There
can be no assurance that the Funds will achieve their investment objectives.  (A
complete list of the  investment  limitations  that cannot be changed  without a
vote of  shareholders  is contained in the Statement of  Additional  Information
under "Investment Objectives and Policies.")

         The Funds may not:

         1. Borrow money,  except that a Fund may (i) borrow money for temporary
or emergency  purposes (not for leveraging or investment) from banks, or subject
to specific  authorization  by the SEC,  from funds advised by the Adviser or an
affiliate  of the  Adviser,  and (ii) engage in reverse  repurchase  agreements;
provided that (i) and (ii) in combination  do not exceed  one-third of the value
of the Fund's total assets  (including  the amount  borrowed)  less  liabilities
(other than borrowings).  The Funds may not mortgage,  pledge or hypothecate any
assets  except  in  connection  with  such  borrowings  and  reverse  repurchase
agreements and then only in amounts not exceeding  one-third of the value of the
particular  Fund's  total  assets  at the  time  of such  borrowing.  Additional
investments  will not be made by a Fund when borrowings  exceed 5% of the Fund's
assets.

         2. Purchase any  securities  which would cause 25% or more of the value
of its  total  assets  at the  time  of  such  purchase  to be  invested  in the
securities of one or more issuers conducting their principal business activities
in the same industry,  except that Prime Value Money Market Fund will invest 25%
or more of the  value of its total  assets  in  obligations  of  issuers  in the
banking industry or in obligations,  such as repurchase  agreements,  secured by
such  obligations  (unless  the  Fund  is in a  temporary  defensive  position);
provided  that  there is no  limitation  with  respect  to  investments  in U.S.
Government  securities  or,  in the case of Prime  Money  Market  Fund,  in bank
instruments issued by domestic banks.

         3.  Make  loans  except  that a Fund  may (i)  purchase  or  hold  debt
obligations in accordance with its investment objective and policies, (ii) enter
into repurchase agreements for securities,  (iii) lend portfolio securities, and
(iv) with the exception of Government  Obligations Money Market Fund, subject to
specific  authorization  by the SEC,  lend money to other  funds  advised by the
Adviser or an affiliate of the Adviser.

                                       14

<PAGE>

         Each Fund may, in the future, seek to achieve its investment  objective
by  investing  all of its assets in a no-load,  open-end  management  investment
company having the same investment  objective and policies and substantially the
same  investment  restrictions  as those  applicable to the Fund. In such event,
each Fund's investment  advisory agreement would be terminated.  Such investment
would be made only if the Trust's Board of Trustees  believes that the aggregate
per share expenses of each class of the Fund and such other  investment  company
will be less than or approximately equal to the expenses which each class of the
Fund  would  incur if the Fund were to  continue  to retain the  services  of an
investment  adviser  for the Fund and the assets of the Fund were to continue to
be invested directly in portfolio securities.

                        PURCHASE AND REDEMPTION OF SHARES

         To allow the  Adviser to manage the Funds  effectively,  investors  are
strongly  urged to initiate all  investments  or  redemptions  of Fund shares as
early in the day as possible and to notify  Lehman  Brothers at least one day in
advance of transactions in excess of $5 million.

PURCHASE PROCEDURES

         Shares of the  Funds  are sold at the net asset  value per share of the
Fund next determined after receipt of a purchase order by Lehman  Brothers,  the
Distributor of the Fund's shares.  Purchase  orders for shares are accepted only
on days on which both the New York Stock  Exchange and the Federal  Reserve Bank
of Boston are open for business and must be transmitted to Lehman  Brothers,  by
telephone at 1-800-851-3134 or through Lehman Brothers ExpressNET,  an automated
order entry system designed  specifically for the Trust ("LEX").  Orders for the
purchase of shares must be made according to the following  schedule.  Purchases
of shares will be effective  and  dividends  will begin to accrue on the date of
purchase if purchase orders comply with the following schedule.

*    All times stated are Eastern time.

         Payment for Fund shares may be made only in federal  funds  immediately
available to Boston Safe Deposit and Trust Company ("Boston Safe").  Payment for
orders  which are not received or accepted by Lehman  Brothers  will be returned
after prompt  inquiry to the sending  institution.  A Fund may in its discretion
reject any order for shares.  Any person  entitled to receive  compensation  for
selling or servicing shares of the Funds may receive different  compensation for
selling or servicing one Class of shares over another Class.

         The minimum aggregate initial investment by an institution in the Funds
is $1 million  (with not less than $25,000  invested in any one Fund);  however,
broker-dealers  and other  institutional  investors may set a higher minimum for
their customers.  To reach the minimum Trust-wide initial investment,  purchases
of shares may be  aggregated  over a period of six  months.  There is no minimum
subsequent investment.

         Conflicts  of  interest  restrictions  may  apply  to an  institution's
receipt of  compensation  paid by the Funds on fiduciary funds that are invested
in Class E Shares.  See also "Management of the Funds - Service  Organizations."
Institutions,  including  banks regulated by the Comptroller of the Currency and
investment  advisers and other money managers subject to the jurisdiction of the
SEC,  the  Department  of Labor or state  securities  commissions,  are urged to
consult their legal advisers before investing fiduciary funds in Class E Shares.

REDEMPTION PROCEDURES

         Redemption  orders must be transmitted to Lehman  Brothers by telephone
at  1-800-851-3134 or through LEX on a day that both the New York Stock Exchange
and the  Federal  Reserve  Bank of Boston  are open for  business.  Payment  for
redeemed shares will be made according to the following schedule.

*All times stated are Eastern time.

         Shares are  redeemed at the net asset  value per share next  determined
after Lehman Brothers' receipt of the redemption  order.  While the Funds intend
to use their best efforts to maintain  their net asset value per share at $1.00,
the proceeds  paid to an investor upon  redemption  may be more or less than the
amount  invested  depending  upon a  share's  net  asset  value  at the  time of
redemption.

         The Funds reserve the right to wire  redemption  proceeds  within seven
days after receiving the redemption order if, in the judgment of the Adviser, an
earlier payment could adversely affect the Funds. The Funds shall have the right
to redeem  involuntarily  shares in any  account at their net asset value if the
value of the account is less than $10,000 after 60 days' prior written notice to
the investor.  Any such redemption  shall be effected at the net asset value per
share next  determined  after the  redemption  order is  entered.  If during the
60-day  period the  investor  increases  the value of its  account to $10,000 or
more, no such  redemption  shall take place.  In addition,  the Funds may redeem
shares  involuntarily  or suspend the right of redemption as permitted under the
Investment  Company Act of 1940,  as amended (the "1940 Act"),  or under certain
special circumstances described in the Statement of Additional Information under
"Additional Purchase and Redemption Information."

         The ability to give  telephone  instructions  for the  redemption  (and
purchase or exchange) of shares is  automatically  established  on an investor's
account.  However,  the Funds  reserve  the right to refuse a  redemption  order
transmitted  by telephone if it is believed  advisable to do so.  Procedures for
redeeming  Fund shares by telephone may be modified or terminated at any time by
the Funds or Lehman Brothers.  In addition,  neither the Funds,  Lehman Brothers
nor FDISG will be responsible for the authenticity of telephone instructions for
the  purchase,  redemption  or exchange  of shares  where the  instructions  are
reasonably believed to be genuine.  Accordingly, the investor will bear the risk
of loss.  The Funds will  attempt to confirm  that  telephone  instructions  are
genuine and will use such procedures as are considered reasonable, including the
recording  of telephone  instructions.  To the extent that the Funds fail to use
reasonable procedures to verify the genuineness of telephone  instructions,  the
Funds or their service  providers may be liable for such instructions that prove
to be fraudulent or unauthorized.

EXCHANGE PROCEDURES

         The Exchange Privilege enables an investor to exchange shares of a Fund
without  charge for shares of the same class of other Funds which have different
investment objectives that may be of interest to investors.  To use the Exchange
Privilege,  exchange  instructions must be given to Lehman Brothers by telephone
or through LEX. See "Redemption  Procedures." In exchanging  shares, an investor
must meet the minimum initial  investment  requirement of the other Fund and the
shares  involved  must be  legally  available  for sale in the  state  where the
investor resides.  Before any exchange, the investor must also obtain and should
review  a copy of the  current  prospectus  of the  Funds.  Prospectuses  may be
obtained  from  Lehman  Brothers  by  calling  1-800-368-5556.  Shares  will  be
exchanged at the net asset value next  determined  after  receipt of an exchange
request in proper form. The exchange of shares of one Fund for shares of another
Fund is treated for federal income tax purposes as a sale of the shares given in
exchange by the investor and, therefore,  an investor may realize a taxable gain
or loss. The Funds reserve the right to reject any exchange  request in whole or
in part.  The Exchange  Privilege may be modified or terminated at any time upon
notice to investors.

VALUATION OF SHARES-NET ASSET VALUE

         Each Fund's net asset value per share for purposes of pricing  purchase
and redemption orders is determined by the Fund's Administrator on each weekday,
with the exception of those holidays on which either the New York Stock Exchange
or the Federal  Reserve  Bank of Boston is closed,  according  to the  following
schedule.

</TABLE>

*All times stated are Eastern time.

         Currently,  one or both of the New York Stock  Exchange and the Federal
Reserve Bank of Boston are closed on the customary national business holidays of
New Year's Day, Martin Luther King, Jr.'s Birthday  (observed),  Presidents' Day
(Washington's Birthday), Good Friday, Memorial Day, Independence Day, Labor Day,
Columbus Day (observed),  Veterans Day,  Thanksgiving Day and Christmas Day, and
on the preceding Friday or subsequent Monday when one of these holidays falls on
a Saturday or Sunday, respectively. The net asset value per share of Fund shares
is calculated  separately  for each class by adding the value of all  securities
and other  assets of the  Fund,  subtracting  class  specific  liabilities,  and
dividing the result by the total  number of the Fund's  outstanding  shares.  In
computing net asset value, each Fund uses the amortized cost method of valuation
as  described in the  Statement  of  Additional  Information  under  "Additional
Purchase  and  Redemption  Information."  A Fund's net asset value per share for
purposes of pricing purchase and redemption  orders is determined  independently
of the net asset values of the shares of each other Fund.

OTHER MATTERS

         Fund  shares  are  sold  and  redeemed  without  charge  by the  Funds.
Institutional  investors  purchasing  or holding Fund shares for their  customer
accounts  may  charge  customers  fees for cash  management  and other  services
provided  in  connection  with their  accounts.  A customer  should,  therefore,
consider the terms of its account with an  institution  before  purchasing  Fund
shares.  An  institution  purchasing  or redeeming  Fund shares on behalf of its
customers  is  responsible  for  transmitting   orders  to  Lehman  Brothers  in
accordance with its customer agreements.

                                    DIVIDENDS

         Investors of a Fund are entitled to dividends and distributions arising
only  from the net  investment  income  and  capital  gains,  if any,  earned on
investments  held by that Fund.  Each Fund's net  investment  income is declared
daily as a dividend  to shares  held of record at the close of  business  on the
date of  declaration.  Shares begin  accruing  dividends on the day the purchase
order for the shares is effective and continue to accrue  dividends  through the
day before such shares are redeemed. Dividends are paid monthly by wire transfer
within five  business  days after the end of the month or within  five  business
days after a redemption  of all of an investor's  shares of a particular  class.
The Funds do not expect to realize net long-term capital gains.

         Dividends  are  determined  in the same manner and are paid in the same
amount  for each Fund  share,  except  that  shares of each  class  bear all the
expenses associated with that specific class.

         Institutional investors may elect to have their dividends reinvested in
additional  full and fractional  shares of the same class of shares with respect
to which such  dividends  are  declared at the net asset value of such shares on
the  payment  date.  Reinvested  dividends  receive  the same tax  treatment  as
dividends paid in cash. Such election,  or any revocation thereof,  must be made
in  writing  to Lehman  Brothers,  260  Franklin  Street,  15th  Floor,  Boston,
Massachusetts 02110-9624,  and will become effective after its receipt by Lehman
Brothers, with respect to dividends paid.

         FDISG,  as Transfer  Agent,  will send each investor or its  authorized
representative  an annual statement  designating the amount of any dividends and
capital gains distributions, if any, made during each year and their federal tax
qualification.

                                      TAXES

         Each Fund  qualified in its last taxable year and intends to qualify in
future years as a  "regulated  investment  company"  under the Code. A regulated
investment  company is exempt from federal income tax on amounts  distributed to
its investors.

         Qualification  as a regulated  investment  company under the Code for a
taxable  year  requires,  among  other  things,  that a Fund  distribute  to its
investors at least 90% of its investment  company  taxable income for such year.
In  general,  a Fund's  investment  company  taxable  income will be its taxable
income  (including  dividends and short-term  capital gains,  if any) subject to
certain  adjustments and excluding the excess of any net long-term capital gains
for the taxable  year over the net  short-term  capital  loss,  if any, for such
year.  Each Fund  intends  to  distribute  substantially  all of its  investment
company taxable income each year. Such distributions will be taxable as ordinary
income to Fund investors who are not currently exempt from federal income taxes,
whether such income is received in cash or reinvested in additional  shares.  It
is  anticipated  that none of a Fund's  distributions  will be eligible  for the
dividends  received  deduction  for  corporations.  The  Funds do not  expect to
realize long-term capital gains and,  therefore,  do not contemplate  payment of
any "capital gain dividends" as described in the Code.

         Dividends  derived  from  exempt-interest  income from  Tax-Free  Money
Market  Fund and  Municipal  Money  Market  Fund may be  treated  by the  Fund's
investors as items of interest  excludable from their gross income under Section
103(a) of the Code, unless under the circumstances  applicable to the particular
investor the exclusion would be disallowed.

         Municipal  Money Market Fund may hold  without  limit  certain  private
activity bonds issued after August 7, 1986.  Investors must include,  as an item
of  tax  preference,  the  portion  of  dividends  paid  by  the  Fund  that  is
attributable to interest on such bonds in determining liability (if any) for the
federal  alternative  minimum tax.  Noncorporate  taxpayers,  depending on their
individual tax status,  may be subject to  alternative  minimum tax at a blended
rate between 26% and 28%. Corporate  taxpayers may be subject to (1) alternative
minimum tax at a rate of 20% of the excess of their alternative  minimum taxable
income  ("AMTI")  over the  exemption  amount,  and (2) the  environmental  tax.
Corporate investors must also take all exempt-interest dividends into account in
determining   certain   adjustments   for   federal   alternative   minimum  and
environmental tax purposes. The


                                       18

<PAGE>

determining  adjustments for federal  alternative  minimum and environmental tax
purposes  environmental tax applicable to corporations is imposed at the rate of
 .12% on the excess of the  corporation's  modified federal  alternative  minimum
taxable income over $2,000,000.

         To the extent,  if any,  dividends  paid to investors by Tax-Free Money
Market Fund or Municipal  Money  Market Fund are derived from taxable  income or
from long-term or short-term  capital  gains,  such dividends will not be exempt
from federal income tax,  whether such dividends are paid in the form of cash or
additional shares, and may also be subject to state and local taxes.

         In addition  to federal  taxes,  an  investor  may be subject to state,
local or foreign  taxes on payments  received from a Fund. A state tax exemption
may be  available  in some  states to the extent  distributions  of the Fund are
derived from  interest on certain U.S.  Government  securities  or on securities
issued by public  authorities  in the state.  The Funds will  provide  investors
annually with information about federal income tax consequences of distributions
made each year.  Investors should be aware of the application of their state and
local tax laws to investments in the Funds.

         Investors  will be advised at least  annually as to the federal  income
tax status of distributions made to them each year.

         The  foregoing  discussion  is  only a  brief  summary  of  some of the
important  federal  tax  considerations  generally  affecting  a  Fund  and  its
shareholders.  No  attempt  is made to  present a  detailed  explanation  of the
federal,  state or local income tax  treatment of a Fund or its  investors,  and
this  discussion  is not  intended as a  substitute  for  careful tax  planning.
Accordingly,  potential investors in the Funds should consult their tax advisers
with  specific  reference  to their  own tax  situation.  See the  Statement  of
Additional Information for a further discussion of tax consequences of investing
in shares of the Funds.

                             MANAGEMENT OF THE FUNDS

         The business and affairs of the Funds are managed  under the  direction
of  the  Trust's  Board  of  Trustees.  The  Trustees  approve  all  significant
agreements  between the Trust and the persons or companies that furnish services
to the Funds, including agreements with its Distributor, Adviser, Administrator,
Transfer  Agent  and  Custodian.  The  day-to-day  operations  of the  Funds are
delegated to the Funds' Adviser and  Administrator.  The Statement of Additional
Information contains general background  information  regarding each Trustee and
executive officer of the Trust.

duties and other applicable law.

SERVICE ORGANIZATIONS

         Under a Plan of  Distribution  (the  "Plan")  adopted  pursuant to Rule
12b-1 under the 1940 Act,  Class E Shares bear fees ("Rule 12b-1 fees")  payable
by the Funds at the aggregate rate of up to .15% (on an annualized basis) of the
average  daily net asset value of such shares to Lehman  Brothers for  providing
certain services to the Funds and holders of Class E Shares. Lehman Brothers may
retain all the payments  made to it under the Plan or may enter into  agreements
with and make payments of up to .15% to  institutional  investors such as banks,
savings  and  loan  associations  and  other  financial  institutions  ("Service
Organizations") for the provision of a portion of such services. These services,
which are described more fully in the Statement of Additional  Information under
"Management  of the Funds -- Service  Organizations,"  include  aggregating  and
processing  purchase and redemption  requests from  shareholders and placing net
purchase  and  redemption  orders  with  Lehman  Brothers;  processing  dividend
payments  from the  Funds  on  behalf  of  shareholders;  providing  information
periodically  to shareholders  showing their positions in shares;  arranging for
bank  wires;  responding  to  shareholder  inquiries  relating  to the  services
provided  by  Lehman   Brothers  or  the  Service   Organization   and  handling
correspondence;  and acting as shareholder of record and nominee.  The Plan also
allows Lehman Brothers to use its own resources to provide distribution services
and  shareholder  services.  Under  the  terms of  related  agreements,  Service
Organizations  are required to provide to their  shareholders  a schedule of any
fees that they may charge  shareholders in connection with their  investments in
Class E Shares.

EXPENSES

         Each Fund bears all its own expenses.  A Fund's expenses include taxes,
interest,  fees and  salaries of the Trust's  trustees  and officers who are not
directors,  officers or employees of the Fund's service  contractors,  SEC fees,
state   securities   qualification   fees,   costs  of  preparing  and  printing
prospectuses  for  regulatory   purposes  and  for  distribution  to  investors,
advisory,  administration  and  distribution  fees,  charges  of the  custodian,
administrator,   transfer   agent  and  dividend   disbursing   agent,   Service
Organization  fees,  certain  insurance  premiums,  outside


                                       20

<PAGE>

auditing  and legal  expenses,  costs of  shareholder  reports  and  shareholder
meetings and any extraordinary  expenses. Each Fund also pays for brokerage fees
and  commissions  (if any) in connection with the purchase and sale of portfolio
securities.  In order to maintain a competitive  expense ratio,  the Adviser and
Administrator  have voluntarily  agreed to waive fees and reimburse  expenses to
the extent  necessary  to maintain  an  annualized  expense  ratio at a level no
greater than .33% of average daily net assets (.18%  excluding  Rule 12b-1 fees)
with respect to the Funds. This voluntary waiver and  reimbursement  arrangement
will not be changed  unless  investors  are  provided at least 60 days'  advance
notice. In addition,  these service providers have agreed to reimburse the Funds
to the extent  required by  applicable  state law for certain  expenses that are
described  in the  Statement  of  Additional  Information.  Any fees  charged by
Service  Organizations  or other  institutional  investors to their customers in
connection  with  investments  in Fund  shares  are not  reflected  in a  Fund's
expenses.

                             PERFORMANCE AND YIELDS

         From time to time, the "yields" and "effective  yields" with respect to
all Funds and "tax-equivalent yields" with respect to Tax-Free Money Market Fund
and  Municipal  Money Market Fund shares may be quoted in  advertisements  or in
reports to shareholders. Yield quotations are computed separately for each class
of shares. The "yield" quoted in advertisements for a particular class of shares
refers to the income  generated by an investment in such shares over a specified
period (such as a seven-day period) identified in the advertisement. This income
is then  "annualized;" that is, the amount of income generated by the investment
during that period is assumed to be generated each such period over a 52-week or
one-year period and is shown as a percentage of the  investment.  The "effective
yield" is calculated  similarly  but, when  annualized,  the income earned by an
investment in a particular  class is assumed to be  reinvested.  The  "effective
yield" will be  slightly  higher  than the  "yield"  because of the  compounding
effect of this assumed reinvestment. The "tax-equivalent yield" demonstrates the
level of taxable yield necessary to produce an after-tax  yield  equivalent to a
Fund's  tax-free yield for each class of shares.  It is calculated by increasing
the yield  (calculated as above) by the amount  necessary to reflect the payment
of federal  taxes at a stated rate.  The  "tax-equivalent  yield" will always be
higher than the "yield."

         A Fund's  performance  may be compared to those of other  mutual  funds
with similar  objectives,  to other relevant indices, or to rankings prepared by
independent  services or other financial or industry  publications  that monitor
the performance of mutual funds. For example, such data are reported in national
financial publications such as Morningstar, Inc., Barron's, IBC/Donoghue's Money
Fund Report(R), The Wall Street Journal and The New York Times; reports prepared
by Lipper  Analytical  Services,  Inc; and  publications  of a local or regional
nature.

         A  Fund's  yield  figures  for  a  class  of  shares   represent   past
performance,  will fluctuate and should not be considered as  representative  of
future results. The yield of any investment is generally a function of portfolio
quality and  maturity,  type of  investment  and  operating  expenses.  Any fees
charged by Service  Organizations or other  institutional  investors directly to
their customers in connection with  investments in Fund shares are not reflected
in a Fund's  expenses or yields;  and, such fees,  if charged,  would reduce the
actual return  received by customers on their  investments.  The methods used to
compute  a Fund's  yields  are  described  in more  detail in the  Statement  of
Additional  Information.  Investors may call  1-800-238-2560  to obtain  current
yield information.

                     DESCRIPTION OF SHARES AND MISCELLANEOUS

         The Trust is a Massachusetts business trust established on November 25,
1992. The Trust's Declaration of Trust authorizes the Board of Trustees to issue
an unlimited number of full and fractional shares of beneficial  interest in the
Trust  and to  classify  or  reclassify  any  unissued  shares  into one or more
additional  classes of shares.  The Trust is an open-end  management  investment
company,  which currently offers seven portfolios.  The Trust has authorized the
issuance  of seven  classes  of  shares  for  Prime  Value  Money  Market  Fund,
Government  Obligations  Money Market Fund and  Municipal  Money Market Fund and
four  classes of shares for Prime  Money  Market  Fund,  Cash  Management  Fund,
Treasury  Instruments  Money Market Fund II, and Tax-Free Money Market Fund. The
issuance  of separate  classes of shares is  intended  to address the  different
service needs of different types of investors.  The Declaration of Trust further
authorizes  the Trustees to classify or reclassify  any class of shares into one
or more sub-classes.

         The  Trust  does  not  presently  intend  to hold  annual  meetings  of
shareholders  except as required by the 1940 Act or other  applicable  law.  The
Trust will call a meeting of  shareholders  for the  purpose of voting  upon the


                                       21

<PAGE>

question of removal of a member of the Board of Trustees upon written request of
shareholders owning at least 10% of the outstanding shares of the Trust entitled
to vote.

         Each Fund share  represents  an equal,  proportionate  interest  in the
assets belonging to the Fund. Each share, which has a par value of $.001, has no
preemptive  or conversion  rights.  When issued for payment as described in this
Prospectus, Fund shares will be fully paid and non-assessable.

         Holders  of the Fund's  shares  will vote in the  aggregate  and not by
class on all matters, except where otherwise required by law and except when the
Board of Trustees  determines  that the matter to be voted upon affects only the
shareholders of a particular class. Further, shareholders of the Funds will vote
in the  aggregate  and not by portfolio  except as otherwise  required by law or
when the Board of Trustees  determines  that the matter to be voted upon affects
only the  interests  of the  shareholders  of a  particular  portfolio  (see the
Statement of Additional  Information  under "Additional  Description  Concerning
Fund Shares" for  examples  where the 1940 Act  requires  voting by  portfolio).
Shareholders  of the Trust are  entitled  to one vote for each full  share  held
(irrespective of class or portfolio) and fractional votes for fractional  shares
held. Voting rights are not cumulative;  and,  accordingly,  the holders of more
than 50% of the aggregate shares of the Trust may elect all of the trustees.

         For  information  concerning the redemption of Fund shares and possible
restrictions on their transferability, see "Purchase and Redemption of Shares."

THE TRUST

	Lehman Brothers Institutional Funds Group Trust (the "Trust") 
is an open-end management investment company. The Trust currently 
includes a family of portfolios, two of which are Prime Money 
Market Fund and Prime Value Money Market Fund (individually, a 
"Fund"; collectively, the "Funds"). 

	Although the Funds have the same Investment Adviser, Lehman 
Brothers Global Asset Management, Inc. (the "Adviser"), and have 
comparable investment objectives, their yields will normally vary 
due to their differing cash flows and their differing types of 
portfolio securities (for example, Prime Value Money Market Fund 
invests in obligations of foreign branches of U.S. banks and 
foreign banks and corporate issuers while Prime Money Market Fund 
does not). 

	THIS STATEMENT OF ADDITIONAL INFORMATION AND THE FUNDS' 
PROSPECTUSES RELATE PRIMARILY TO THE FUNDS AND DESCRIBE ONLY THE 
INVESTMENT OBJECTIVES AND POLICIES, OPERATIONS, CONTRACTS AND OTHER 
MATTERS RELATING TO EACH FUND. INVESTORS WISHING TO OBTAIN SIMILAR 
INFORMATION REGARDING THE TRUST'S OTHER PORTFOLIOS MAY OBTAIN 
INFORMATION DESCRIBING THEM BY CONTACTING LEHMAN BROTHERS AT 
1-800-368-5556.

INVESTMENT OBJECTIVE AND POLICIES

	As stated in the Funds' Prospectuses, the investment objective 
of each Fund is to provide current income and stability of 
principal by investing in a portfolio of money market instruments. 
The following policies supplement the description of each Fund's 
investment objective and policies in the Prospectuses. 

	The Funds are managed to provide stability of capital while 
achieving competitive yields. The Adviser intends to follow a 
value-oriented, research-driven and risk-averse investment 
strategy, engaging in a full range of economic, strategic, credit 
and market-specific analyses in researching potential investment 
opportunities. 

Portfolio Transactions

	Subject to the general control of the Trust's Board of 
Trustees, the Adviser is responsible for, makes decisions with 
respect to and places orders for all purchases and sales of 
portfolio securities for a Fund. The Adviser purchases portfolio 
securities for the Funds either directly from the issuer or from 
dealers who specialize in money market instruments. Such purchases 
are usually without brokerage commissions. In making portfolio 
investments, the Adviser seeks to obtain the best net price and the 
most favorable execution of orders. To the extent that the 
execution and price offered by more than one dealer are comparable, 
the Adviser may, in its discretion, effect transactions in 
portfolio securities with dealers who provide the Trust with 
research advice or other services. 

	The Adviser may seek to obtain an undertaking from issuers of 
commercial paper or dealers selling commercial paper to consider 
the repurchase of such securities from a Fund prior to their 
maturity at their original cost plus interest (interest may 
sometimes be adjusted to reflect the actual maturity of the 
securities) if the Adviser believes that a Fund's anticipated need 
for liquidity makes such action desirable. Certain dealers (but not 
issuers) have charged and may in the future charge a higher price 
for commercial paper where they undertake to repurchase prior to 
maturity. The payment of a higher price in order to obtain such an 
undertaking reduces the yield which might otherwise be received by 
a Fund on the commercial paper. The Trust's Board of Trustees has 
authorized the Adviser to pay a higher price for commercial paper 
where it secures such an undertaking if the Adviser believes that 
the prepayment privilege is desirable to assure a Fund's liquidity 
and such an undertaking cannot otherwise be obtained. 

	Investment decisions for each Fund are made independently from 
those for another of the Trust's portfolios or other investment 
company portfolios or accounts advised by the Adviser. Such other 
portfolios may also invest in the same securities as the Funds. 
When purchases or sales of the same security are made at 
substantially the same time on behalf of such other portfolios, 
transactions are averaged as to price, and available investments 
allocated as to amount, in a manner which the Adviser believes to 
be equitable to each portfolio, including the Funds. In some 
instances, this investment procedure may adversely affect the price 
paid or received by a Fund or the size of the position obtainable 
for a Fund. To the extent permitted by law, the Adviser may 
aggregate the securities to be sold or purchased for a Fund with 
those to be sold or purchased for such other portfolios in order to 
obtain best execution. 

	The Funds will not execute portfolio transactions through, 
acquire portfolio securities issued by, make savings deposits in, 
or enter into repurchase agreements with Lehman Brothers or the 
Adviser or any affiliated person (as such term is defined in the 
Investment Company Act of 1940, as amended (the "1940 Act")) of any 
of them, except to the extent permitted by the Securities and 
Exchange Commission (the "SEC"). In addition, with respect to such 
transactions, securities, deposits and agreements, the Funds will 
not give preference to Service Organizations with which a Fund 
enters into agreements.  (See the Prospectuses, "Management of the 
Fund - Service Organizations"). 

	The Funds may seek profits through short-term trading. Each 
Fund's annual portfolio turnover will be relatively high, but 
brokerage commissions are normally not paid on money market 
instruments and a Fund's portfolio turnover is not expected to have 
a material effect on its net income. Each Fund's portfolio turnover 
rate is expected to be zero for regulatory reporting purposes.

Additional Information on Portfolio Instruments

	With respect to the variable rate notes and variable rate 
demand notes described in the Prospectuses, the Adviser will 
consider the earning power, cash flows and other liquidity ratios 
of the issuers of such notes and will continuously monitor their 
financial ability to meet payment obligations when due. 

	The repurchase price under the repurchase agreements described 
in the Funds' Prospectuses generally equals the price paid by a 
Fund plus interest negotiated on the basis of current short-term 
rates (which may be more or less than the rate on the securities 
underlying the repurchase agreement). The collateral underlying 
each repurchase agreement entered into by the Funds will consist 
entirely of direct obligations of the U.S. government and 
obligations issued or guaranteed by U.S. government agencies or 
instrumentalities. Securities subject to repurchase agreements will 
be held by the Trust's Custodian, sub-custodian or in the Federal 
Reserve/Treasury book-entry system. Repurchase agreements are 
considered to be loans by the Funds under the 1940 Act. 

	As stated in the Funds' Prospectuses, a Fund may purchase 
securities on a "when issued" basis (i.e., for delivery beyond the 
normal settlement date at a stated price and yield). When a Fund 
agrees to purchase when-issued securities, the Custodian will set 
aside cash or liquid portfolio securities equal to the amount of 
the commitment in a separate account. Normally, the Custodian will 
set aside portfolio securities to satisfy a purchase commitment, 
and in such a case that Fund may be required subsequently to place 
additional assets in the separate account in order to ensure that 
the value of the account remains equal to the amount of such Fund's 
commitment. It may be expected that a Fund's net assets will 
fluctuate to a greater degree when it sets aside portfolio 
securities to cover such purchase commitments than when it sets 
aside cash. Because a Fund will set aside cash or liquid assets to 
satisfy its purchase commitments in the manner described, such 
Fund's liquidity and ability to manage its portfolio might be 
affected in the event its commitments to purchase when-issued 
securities ever exceeded 25% of the value of its assets. When a 
Fund engages in when-issued transactions, it relies on the seller 
to consummate the trade. Failure of the seller to do so may result 
in a Fund's incurring a loss or missing an opportunity to obtain a 
price considered to be advantageous. Neither Fund intends to 
purchase when-issued securities for speculative purposes but only 
in furtherance of its investment objective. Each Fund reserves the 
right to sell these securities before the settlement date if it is 
deemed advisable. 

	Examples of the types of U.S. Government obligations that may 
be held by a Fund include, in addition to U.S. Treasury Bills, the 
obligations of the Federal Housing Administration, Farmers Home 
Administration, Export-Import Bank of the United States, Small 
Business Administration, Government National Mortgage Association, 
Federal National Mortgage Association, Federal Financing Bank, 
General Services Administration, Student Loan Marketing 
Association, Central Bank for Cooperatives, Federal Home Loan 
Banks, Federal Home Loan Mortgage Corporation, Federal Intermediate 
Credit Banks, Federal Land Banks, Federal Farm Credit Banks, 
Maritime Administration, Resolution Trust Corporation, Tennessee 
Valley Authority, U.S. Postal Service and Washington D.C. Armory 
Board. 

	For purposes of Prime Value Money Market Fund's investment 
policies with respect to obligations of issuers in the banking 
industry, the assets of a bank or savings institution will be 
deemed to include the assets of its domestic and foreign branches. 
Prime Value Money Market Fund's investments in the obligations of 
foreign branches of U.S. banks and of foreign banks and other 
foreign issuers may subject Prime Value Money Market Fund to 
investment risks that are different in some respects from those of 
investment in obligations of U.S. domestic issuers. Such risks 
include future political and economic developments, the possible 
seizure or nationalization of foreign deposits, the possible 
establishment of exchange controls or the adoption of other foreign 
governmental restrictions which might adversely affect the payment 
of principal and interest on such obligations. In addition, foreign 
branches of U.S. banks and foreign banks may be subject to less 
stringent reserve requirements and foreign issuers generally are 
subject to different accounting, auditing, reporting and record 
keeping standards than those applicable to U.S. issuers. Prime 
Value Money Market Fund will acquire securities issued by foreign 
branches of U.S. banks or foreign issuers only when the Adviser 
believes that the risks associated with such instruments are 
minimal. 

	Among the bank obligations in which the Funds may invest are 
notes issued by banks. These notes, which are exempt from 
registration under federal securities laws, are not deposits of the 
banks and are not insured by the Federal Deposit Insurance 
Corporation or any other insurer. Holders of notes rank on a par 
with other unsecured and unsubordinated creditors of the banks. 
Notes may be sold at par or sold on a discount basis and may bear 
fixed or floating rates of interest. 

	Each Fund may invest in asset-backed and receivable-backed 
securities. Several types of asset-backed and receivable-backed 
securities have been offered to investors, including interests in 
pools of credit card receivables and motor vehicle retail 
installment sales contracts and security interests in the vehicles 
securing the contracts. Payments of principal and interest on these 
securities are passed through to certificate holders. In addition, 
asset-backed securities often carry credit protection in the form 
of extra collateral, subordinate certificates, cash reserve 
accounts and other enhancements. An investor's return on these 
securities may be affected by early prepayment of principal on the 
underlying receivables or sales contracts.  Any asset-backed or 
receivable-backed securities held by the Funds must comply with the 
portfolio maturity and quality requirements contained in Rule 2a-7 
under the 1940 Act. Each Fund will monitor the performance of these 
investments and will not acquire any such securities unless rated 
in the highest rating category by at least two nationally 
recognized statistical rating organizations ("NRSROs"). 

	As stated in the Funds' Prospectuses, each Fund may invest in 
obligations issued by state and local governmental entities. 
Municipal securities are issued by various public entities to 
obtain funds for various public purposes, including the 
construction of a wide range of public facilities, the refunding of 
outstanding obligations, the payment of general operating expenses 
and the extension of loans to public institutions and facilities. 
Private activity bonds that are issued by or on behalf of public 
authorities to finance various privately operated facilities are 
considered to be municipal securities and may be purchased by a 
Fund. Dividends paid by a Fund that are derived from interest on 
such municipal securities would be taxable to that Fund's investors 
for federal income tax purposes. 

	The SEC has adopted Rule 144A under the Securities Act of 
1933, as amended (the "1933 Act"), that allows for a broader 
institutional trading market for securities otherwise subject to 
restrictions on resale to the general public. Rule 144A establishes 
a "safe harbor" from the registration requirements of the 1933 Act 
for resales of certain securities to qualified institutional 
buyers. The Adviser anticipates that the market for certain 
restricted securities such as institutional commercial paper will 
expand further as a result of this regulation and the development 
of automated systems for the trading, clearance and settlement of 
unregistered securities of domestic and foreign issuers, such as 
the PORTAL System sponsored by the National Association of 
Securities Dealers, Inc.

	The Adviser will monitor the liquidity of restricted and other 
illiquid securities under the supervision of the Board of Trustees. 
In reaching liquidity decisions with respect to Rule 144A 
securities, the Adviser will consider, inter alia, the following 
factors: (1) the unregistered nature of a Rule 144A security; 
(2) the frequency of trades and quotes for a Rule 144A security; 
(3) the number of dealers wishing to purchase or sell the Rule 144A 
security and the number of other potential purchasers; (4) dealer 
undertakings to make a market in the Rule 144A security; (5) the 
trading markets for the Rule 144A security; and (6) the nature of 
the Rule 144A security and the nature of the marketplace trades 
(e.g., the time needed to dispose of the Rule 144A security, the 
method of soliciting offers and the mechanics of the transfer). 

	The Appendix to this Statement of Additional Information 
contains a description of the relevant rating symbols used by 
NRSROs for commercial obligations that may be purchased by each 
Fund. 

	 The Funds may invest in mortgage backed securities issued by 
U.S. Government agencies or instrumentalities consisting of 
mortgage pass-through securities or collateralized mortgage 
obligations ("CMOs").  Mortgage pass-through securities in which 
the Funds may invest represent a partial ownership interest in a 
pool of residential mortgage loans and are issued or guaranteed by 
the Government National Mortgage Association ("GNMA"), the Federal 
National Mortgage Association ("FNMA") and the Federal Home Loan 
Mortgage Corporation ("FHLMC").  CMOs are debt obligations 
collateralized by mortgage loans or mortgage pass-through 
securities (collateral collectively referred to as "Mortgage 
Assets").  CMOs in which the Funds may invest are issued by GNMA, 
FNMA and FHLMC.  In a CMO, a series of bonds or certificates are 
usually issued in multiple classes.  Each class of CMOs, often 
referred to as a "tranche," is issued at a specific fixed or 
floating coupon rate and has a stated maturity or final 
distribution date.  Principal prepayments on the Mortgage Assets 
may cause the CMOs to be retired substantially earlier than their 
stated maturities or final distribution dates, resulting in a loss 
of all or part of the premium if any has been paid.  Interest is 
paid or accrues on all classes of the CMOs on a monthly, quarterly 
or semiannual basis.  The Funds expect that mortgage backed 
securities will only be purchased in connection with repurchase 
transactions.

Investment Limitations

	The Funds' Prospectuses summarize certain investment 
limitations that may not be changed without the affirmative vote of 
the holders of a majority of a Fund's outstanding shares (as 
defined below under "Miscellaneous"). Investment limitations 
numbered 1 through 7 may not be changed without such a vote of 
shareholders; investment limitations 8 through 13 may be changed by 
a vote of the Trust's Board of Trustees at any time. 

	A Fund may not: 

 1.	Purchase securities of any one issuer if as a result more than 
5% of the value of the Fund's assets would be invested in the 
securities of such issuer, except that up to 25% of the value of 
the Fund's total assets may be invested without regard to such 5% 
limitation and provided that there is no limitation with respect to 
investments in U.S. Government securities. 

 2.	Borrow money, except that the Fund may (i) borrow money for 
temporary or emergency purposes (not for leveraging or investment) 
from banks or, subject to specific authorization by the SEC, from 
funds advised by the Adviser or an affiliate of the Adviser, and 
(ii) engage in reverse repurchase agreements, provided that (i) and 
(ii) in combination do not exceed one-third of the value of the 
particular Fund's total assets (including the amount borrowed) less 
liabilities (other than borrowings).  A Fund may not mortgage, 
pledge or hypothecate its assets except in connection with such 
borrowings and reverse repurchase agreements and then only in 
amounts not exceeding one-third of the value of the particular 
Fund's total assets.  Additional investments will not be made when 
borrowings exceed 5% of the Fund's assets. 

 3.	Purchase any securities which would cause 25% or more of the 
value of its total assets at the time of such purchase to be 
invested in the securities of one or more issuers conducting their 
principal business activities in the same industry, except that 
Prime Value Money Market Fund will invest 25% or more of the value 
of its total assets in obligations of issuers in the banking 
industry or in obligations, such as repurchase agreements, secured 
by such obligations (unless the Fund is in a temporary defensive 
position); provided that there is no limitation with respect to 
investments in U.S. Government securities or, in the case of Prime 
Money Market Fund, in bank instruments issued by domestic banks. 

 4.	Make loans, except that a Fund may (i) purchase or hold debt 
obligations in accordance with its investment objective and 
policies, (ii) enter into repurchase agreements for securities, 
(iii) lend portfolio securities and (iv) subject to specific 
authorization by the SEC, lend money to other funds advised by the 
Adviser or an affiliate of the Adviser. 

 5.	Act as an underwriter of securities, except insofar as the 
Fund may be deemed an underwriter under applicable securities laws 
in selling portfolio securities. 

 6.	Purchase or sell real estate or real estate limited 
partnerships, provided that the Fund may purchase securities of 
issuers which invest in real estate or interests therein. 

 7.	Purchase or sell commodities contracts, or invest in oil, gas 
or mineral exploration or development programs or in mineral 
leases. 

 8.	Knowingly invest more than 10% of the value of the Fund's 
assets in securities that may be illiquid because of legal or 
contractual restrictions on resale or securities for which there 
are no readily available market quotations. 

 9.	Purchase securities on margin, make short sales of securities 
or maintain a short position. 

10.	Write or sell puts, calls, straddles, spreads or combinations 
thereof. 

11.	Invest in securities if as a result the Fund would then have 
more than 15% (or such lesser amount as set by state securities 
laws) of its total assets in securities of companies (including 
predecessors) with less than three years of continuous operation. 

12.	Purchase securities of other investment companies except as 
permitted under the 1940 Act or in connection with a merger, 
consolidation, acquisition or reorganization. 

13.	Invest in warrants. 

	In order to permit the sale of Fund shares in certain states, 
the Funds may make commitments more restrictive than the investment 
policies and limitations above. Should a Fund determine that any 
such commitments are no longer in its best interests, it will 
revoke the commitment by terminating sales of its shares in the 
state involved. Further, with respect to the above-stated third 
limitation, each Fund will consider wholly owned finance companies 
to be in the industries of their parents, if their activities are 
primarily related to financing the activities of their parents, and 
will divide utility companies according to their services; for 
example, gas, gas transmission, electric and gas, electric and 
telephone will each be considered a separate industry. 

ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

In General

	Information on how to purchase and redeem each Fund's shares 
is included in the Prospectuses. The issuance of shares is recorded 
on a Fund's books, and share certificates are not issued.

	The regulations of the Comptroller of the Currency (the 
"Comptroller") provide that funds held in a fiduciary capacity by a 
national bank approved by the Comptroller to exercise fiduciary 
powers must be invested in accordance with the instrument 
establishing the fiduciary relationship and local law. The Trust 
believes that the purchase of Prime Money Market Fund and Prime 
Value Money Market Fund shares by such national banks acting on 
behalf of their fiduciary accounts is not contrary to applicable 
regulations if consistent with the particular account and proper 
under the law governing the administration of the account. 

	Conflict of interest restrictions may apply to an 
institution's receipt of compensation paid by a Fund on fiduciary 
funds that are invested in a Fund's Class B, Class C or Class E 
shares. Institutions, including banks regulated by the Comptroller 
and investment advisers and other money managers subject to the 
jurisdiction of the SEC, the Department of Labor or state 
securities commissions, are urged to consult their legal advisers 
before investing fiduciary funds in a Fund's Class B, Class C or 
Class E shares. 

	Under the 1940 Act, a Fund may suspend the right of redemption 
or postpone the date of payment upon redemption for any period 
during which the New York Stock Exchange ("NYSE") is closed, other 
than customary weekend and holiday closings, or during which 
trading on the NYSE is restricted, or during which (as determined 
by the SEC by rule or regulation) an emergency exists as a result 
of which disposal or valuation of portfolio securities is not 
reasonably practicable, or for such other periods as the SEC may 
permit. (A Fund may also suspend or postpone the recordation of the 
transfer of its shares upon the occurrence of any of the foregoing 
conditions.) In addition, a Fund may redeem shares involuntarily in 
certain other instances if the Board of Trustees determines that 
failure to redeem may have material adverse consequences to that 
Fund's investors in general. Each Fund is obligated to redeem 
shares solely in cash up to $250,000 or 1% of such Fund's net asset 
value, whichever is less, for any one investor within a 90-day 
period. Any redemption beyond this amount will also be in cash 
unless the Board of Trustees determines that conditions exist which 
make payment of redemption proceeds wholly in cash unwise or 
undesirable. In such a case, a Fund may make payment wholly or 
partly in readily marketable securities or other property, valued 
in the same way as that Fund determines net asset value. See "Net 
Asset Value" below for an example of when such redemption or form 
of payment might be appropriate. Redemption in kind is not as 
liquid as a cash redemption. Investors who receive a redemption in 
kind may incur transaction costs, if they sell such securities or 
property, and may receive less than the redemption value of such 
securities or property upon sale, particularly where such 
securities are sold prior to maturity. 

	Any institution purchasing shares on behalf of separate 
accounts will be required to hold the shares in a single nominee 
name (a "Master Account"). Institutions investing in more than one 
of the Trust's portfolios or classes of shares, must maintain a 
separate Master Account for each Fund's class of shares.  
Sub-accounts may be established by name or number either when the 
Master Account is opened or later. 

Net Asset Value

	Each Fund's net asset value per share is calculated separately 
for each class by dividing the total value of the assets belonging 
to a Fund attributable to a class, less the value of any class-
specific liabilities charged to such Fund, by the total number of 
that Fund's shares of that class outstanding.  "Assets belonging 
to" a Fund consist of the consideration received upon the issuance 
of Fund shares together with all income, earnings, profits and 
proceeds derived from the investment thereof, including any 
proceeds from the sale of such investments, any funds or payments 
derived from any reinvestment of such proceeds, and a portion of 
any general assets of the Trust not belonging to a particular Fund. 
Assets belonging to a Fund are charged with the direct liabilities 
of that Fund and with a share of the general liabilities of the 
Trust allocated on a daily basis in proportion to the relative net 
assets of such Fund and the Trust's other portfolios. 
Determinations made in good faith and in accordance with generally 
accepted accounting principles by the Trust's Board of Trustees as 
to the allocation of any assets or liabilities with respect to a 
Fund are conclusive. 

	As stated in the applicable Prospectuses, in computing the net 
asset value of its shares for purposes of sales and redemptions, 
each Fund uses the amortized cost method of valuation. Under this 
method, a Fund values each of its portfolio securities at cost on 
the date of purchase and thereafter assumes a constant 
proportionate amortization of any discount or premium until 
maturity of the security. As a result, the value of the portfolio 
security for purposes of determining net asset value normally does 
not change in response to fluctuating interest rates. While the 
amortized cost method seems to provide certainty in portfolio 
valuation, it may result in valuations of a Fund's securities which 
are higher or lower than the market value of such securities. 

	In connection with its use of amortized cost valuation, each 
Fund limits the dollar-weighted average maturity of its portfolio 
to not more than 90 days and does not purchase any instrument with 
a remaining maturity of more than thirteen months (397 days) (with 
certain exceptions). The Trust's Board of Trustees has also 
established procedures, pursuant to rules promulgated by the SEC, 
that are intended to stabilize each Fund's net asset value per 
share for purposes of sales and redemptions at $1.00. Such 
procedures include the determination, at such intervals as the 
Board deems appropriate, of the extent, if any, to which a Fund's 
net asset value per share calculated by using available market 
quotations deviates from $1.00 per share. In the event such 
deviation exceeds 1/2 of 1%, the Board will promptly consider what 
action, if any, should be initiated. If the Board believes that the 
amount of any deviation from a Fund's $1.00 amortized cost price 
per share may result in material dilution or other unfair results 
to investors, it will take such steps as it considers appropriate 
to eliminate or reduce to the extent reasonably practicable any 
such dilution or unfair results. These steps may include selling 
portfolio instruments prior to maturity to realize capital gains or 
losses or to shorten a Fund's average portfolio maturity, redeeming 
shares in kind, reducing or withholding dividends, or utilizing a 
net asset value per share determined by using available market 
quotations.

Distributor

	Lehman Brothers acts as the Distributor of each Fund's shares.  
Lehman Brothers, located at 3 World Financial Center, New York, New 
York 10285, is a wholly-owned subsidiary of Lehman Brothers 
Holdings Inc. ("Holdings").  As of December 31, 1995, FMR Corp. 
beneficially owned approximately 11.7%, Nippon Life Insurance 
Company beneficially owned approximately 5.0% and Prudential Asset 
Management beneficially owned approximately 5.0% of the outstanding 
voting securities of Holdings.  Each Fund's shares are sold on a 
continuous basis by Lehman Brothers. The Distributor pays the cost 
of printing and distributing prospectuses to persons who are not 
investors of a Fund (excluding preparation and printing expenses 
necessary for the continued registration of a Fund's shares) and of 
preparing, printing and distributing all sales literature. No 
compensation is payable by a Fund to Lehman Brothers for its 
distribution services. 

	Lehman Brothers is comprised of several major operating 
business units. Lehman Brothers Institutional Funds Group is the 
business group within Lehman Brothers that is primarily responsible 
for the distribution and client service requirements of the Trust 
and its investors. Lehman Brothers Institutional Funds Group has 
been serving institutional clients' investment needs exclusively 
for more than 20 years, emphasizing high quality individualized 
service to clients. 

Investment Adviser

	Lehman Brothers Global Asset Management, Inc. serves as the 
Adviser to each of the Funds.  The Adviser, located at 3 World 
Financial Center, New York, New York 10285, is a wholly-owned 
subsidiary of Holdings.  The investment advisory agreements provide 
that the Adviser is responsible for all investment activities of 
the Funds, including executing portfolio strategy, effecting Fund 
purchase and sale transactions and employing professional portfolio 
managers and security analysts who provide research for the Funds.

	Investment personnel of the Adviser may invest in securities 
for their own account pursuant to a code of ethics that establishes 
procedures for personal investing and restricts certain 
transactions.

	The Investment Advisory Agreement with respect to each of the 
Funds was most recently approved by the Trust's Board of Trustees, 
including a majority of the Trust's "non-interested" Trustees, on 
December 5, 1995 and by shareholders on January 31, 1996.  The 
Investment Advisory Agreements commenced on February 1, 1996 and 
will continue until February 1, 1998 unless terminated or amended 
prior to that date according to its terms.  The Investment Advisory 
Agreements will continue initially  for a two-year period and 
automatically for successive annual periods thereafter provided the 
continuance is approved annually (i) by the Trust's Board of 
Trustees or (ii) by a vote of a "majority" (as defined in the 1940 
Act) of a Fund's outstanding voting securities, except that in 
either event the continuance is also approved by a majority of the 
Trustees of the Trust who are not "interested persons" (as defined 
in the 1940 Act). Each Investment Advisory Agreement may be 
terminated (i) on 60 days' written notice by the Trustees of the 
Trust, (ii) by vote of holders of a majority of a Fund's 
outstanding voting securities, or upon 90 days' written notice by 
Lehman Brothers, or (iii) automatically in the event of its 
assignment (as defined in the 1940 Act).

	Effective February 1, 1996, as compensation for the Adviser's 
services rendered to the Fund, the Adviser is entitled to a fee, 
computed daily and paid monthly, at the annual rate of .20% of the 
average daily net assets of the Fund.  Prior to February 1, 1996, 
the Adviser was entitled to a fee, computed daily and paid monthly, 
at the annual rate of .10% of the average daily net assets of the 
Fund.  For the fiscal period ended January 31, 1994 and for the 
fiscal years ended January 31, 1995 and 1996, the Adviser was 
entitled to receive advisory fees in the following amounts:  the 
Prime Money Market Fund, $1,165,899, $2,386,734 and $4,452,828, 
respectively, and the Prime Value Money Market Fund, $1,106,003, 
$1,858,719, and $2,885,656, respectively.  Waivers by the Adviser 
of advisory fees and reimbursement of expenses to maintain the 
Funds' operating expenses ratios at certain levels amounted to:  
the Prime Money Market Fund, $1,165,899 and $0, respectively, for 
the fiscal period ended January 31, 1994, $1,171,734 and $0, 
respectively, for the fiscal year ended January 31, 1995 and $0.00 
and $0.00, respectively, for the fiscal year ended January 31, 
1996;  and the Prime Value Money Market Fund, $1,106,003 and 
$757,799, respectively for the fiscal period ended January 31, 
1994, $1,388,554 and $0, respectively, for the fiscal year ended 
January 31, 1995  and $0.00 and $0.00, respectively, for the fiscal 
year ended January 31, 1996.  In order to maintain competitive 
expense ratios during 1996 and thereafter, the Adviser and 
Administrator have agreed to voluntary fee waivers and expense 
reimbursements for each of the Funds if total operating expenses 
exceed certain levels.  See "Background and Expense Information" in 
the Prospectuses.

beneficial owner of more than 25% of the outstanding shares of a 
Fund, such investor may be deemed to be a "control person" of that 
Fund for purposes of the 1940 Act.

Administrator and Transfer Agent

	FDISG, a subsidiary of First Data Corporation, is located at 
One Exchange Place, Boston, Massachusetts 02109, and serves as the 
Trust's Administrator and Transfer Agent.  As the Trust's 
Administrator, FDISG has agreed to provide the following services:

rate of .10% of the average daily net assets of each Fund.  FDISG 
pays Boston Safe Deposit and Trust Company ("Boston Safe"), the 
Fund's Custodian, a portion of its monthly administration fee for 
custody services rendered to the Funds.

	Prior to May 6, 1994, The Boston Company Advisors, Inc. 
("TBCA"), a wholly-owned subsidiary of Mellon Bank Corporation 
("Mellon"), served as Administrator of the Funds.  On May 6, 1994, 
FDISG acquired TBCA's third party mutual fund administration 
business from Mellon, and each Fund's administration agreement with 
TBCA was assigned to FDISG.  For the fiscal period ended January 
31, 1994 and the fiscal years ended January 31, 1995 and 1996, the 
Administrator was entitled to receive administration fees in the 
following amounts:  the Prime Money Market Fund - $1,165,899, 
$2,386,734, and $4,452,828 respectively, and the Prime Value Money 
Market Fund - $1,106,003, $1,858,719, and $2,885,656 respectively.  
Waivers by the Administrator of administration fees and 
reimbursement of expenses to maintain the Funds' operating expense 
ratios at certain levels amounted to:  the Prime Money Market Fund 
- - $1,165,899 and $115,300, respectively, for the fiscal period 
ended January 31, 1994; $1,815,227 and $0, respectively, for the 
fiscal year ended January 31, 1995; and $3,282,922 and $0.00 for 
the fiscal year ended January 31, 1996; and the Prime Value Money 
Market Fund - $1,106,003 and $192,939, respectively, for the fiscal 
period ended January 31, 1994; $1,414,970 and $0, respectively, for 
the fiscal period ended January 31, 1995; and $2,127,361 and $0.00 
for the fiscal year ended January 31, 1996.  In order to maintain 
competitive expense ratios during 1996 and thereafter, the Adviser 
and Administrator have agreed to reimburse the Funds if total 
operating expenses exceed certain levels.  See "Background and 
Expense Information" in each Fund's Prospectus.

	Under the transfer agency agreement, FDISG maintains the 
shareholder account records for the Trust, handles certain 
communications between investors and the Trust, distributes 
dividends and distributions payable by the Trust and produces 
statements with respect to account activity for the Trust and its 
investors. For these services, FDISG receives a monthly fee based 
on average net assets and is reimbursed for out-of-pocket expenses. 

Custodian

	Boston Safe, a wholly-owned subsidiary of Mellon, is located 
at One Boston Place, Boston, Massachusetts 02108, and serves as the 
Custodian of the Trust pursuant to a custody agreement. Under the 
custody agreement, Boston Safe holds each Fund's portfolio 
securities and keeps all necessary accounts and records. For its 
services, Boston Safe receives a monthly fee from FDISG based upon 
the month-end market value of securities held in custody and also 
receives securities transaction charges, including out-of-pocket 
expenses. The assets of the Trust are held under bank custodianship 
in compliance with the 1940 Act. 

Service Organizations

	As stated in the Funds' Prospectuses, a Fund will enter into 
an agreement with each financial institution which may purchase 
Class B, Class C or Class E shares. The Fund will enter into an 
agreement with each Service Organization whose customers 
("Customers") are the beneficial owners of Class B, Class C or 
Class E shares that requires the Service Organization to provide 
certain services to Customers in consideration of such Fund's 
payment of .25%, .35% or .15% respectively, of the average daily 
net asset value of the respective Class beneficially owned by the 
Customers. Such services with respect to the Class C shares 
include: (i) aggregating and processing purchase and redemption 
requests from Customers and placing net purchase and redemption 
orders with a Fund's Distributor; (ii) processing dividend payments 
from a Fund on behalf of Customers; (iii ) providing information 
periodically to Customers showing their positions in a Fund's 
shares; (iv) arranging for bank wires; (v) responding to Customer 
inquiries relating to the services performed by the Service 
Organization and handling correspondence; (vi) forwarding investor 
communications from a Fund (such as proxies, investor reports, 
annual and semi-annual financial statements, and dividend, 
distribution and tax notices) to Customers; (vii) acting as 
shareholder of record or nominee; and (viii) other similar account 
administrative services. In addition, a Service Organization at its 
option, may also provide to its Customers of Class C shares (a) a 
service that invests the assets of their accounts in shares 
pursuant to specific or pre-authorized instructions; (b) sub-
accounting with respect to shares beneficially owned by Customers 
or the information necessary for sub-accounting; and (c) 
checkwriting services. Service Organizations that purchase Class C 
shares will also provide assistance in connection with the support 
of the distribution of Class C shares to its Customers, including 
marketing assistance and the forwarding to Customers of sales 
literature and advertising provided by the Distributor of the 
shares.  Holders of Class B shares of a Fund will receive the 
services set forth in (i) and (v) and may receive one or more of 
the services set forth in (ii), (iii), (iv), (vi), (vii) and (viii) 
above.  A Service Organization, at its option, may also provide to 
its Customers of Class B shares services including:  (a) providing 
Customers with a service that invests the assets of their accounts 
in shares pursuant to specific or pre-authorized instruction; 
(b) providing sub-accounting with respect to shares beneficially 
owned by Customers or the information necessary for sub-accounting; 
(c) providing reasonable assistance in connection with the 
distribution of shares to Customers; and (d) providing such other 
similar services as the Fund may reasonably request to the extent 
the Service Organization is permitted to do so under applicable 
statutes, rules, or regulations.  Holders of Class E Shares of a 
Fund will receive the services set forth in (i) and (v), above.  A 
Service Organization, at its option, may also provide to its 
Customers of Class E shares services including those services set 
forth in (ii), (iii), (iv), (vi), (vii) and (viii) above and the 
optional services set forth in (a), (b) and (c) above.

	Each Fund's agreements with Service Organizations are governed 
by a Shareholder Services Plan (the "Plan") that has been adopted 
by the Trust's Board of Trustees under Rule 12b-1 of the 1940 Act.  
Under this Plan, the Board of Trustees reviews, at least quarterly, 
a written report of the amounts expended under each Fund's 
agreements with Service Organizations and the purposes for which 
the expenditures were made. In addition, a Fund's arrangements with 
Service Organizations must be approved annually by a majority of 
the Trust's Trustees, including a majority of the Trustees who are 
not "interested persons" of the Trust as defined in the 1940 Act 
and have no direct or indirect financial interest in such 
arrangements (the "Disinterested Trustees"). 

	The Board of Trustees has approved each Fund's arrangements 
with Service Organizations based on information provided by the 
Trust's service contractors that there is a reasonable likelihood 
that the arrangements will benefit such Fund and its investors by 
affording the Fund greater flexibility in connection with the 
servicing of the accounts of the beneficial owners of its shares in 
an efficient manner. Any material amendment to a Fund's 
arrangements with Service Organizations must be approved by a 
majority of the Trust's Board of Trustees (including a majority of 
the Disinterested Trustees). So long as a Fund's arrangements with 
Service Organizations are in effect, the selection and nomination 
of the members of the Trust's Board of Trustees who are not 
"interested persons" (as defined in the 1940 Act) of the Trust will 
be committed to the discretion of such non-interested Trustees. 

	For the fiscal year ended January 31, 1996, the following 
service fees were paid by Prime Money Market Fund:  Class B shares, 
$966,300.60, Class C shares, $37,692.74, and Class E shares, 
$16,750.28.  For the fiscal year ended January 31, 1995, the 
following service fees were paid by the Prime Money Market Fund:  
Class B shares, $726,035, Class C shares, $60,810, and Class E 
shares, $5,834.  For the period February 8, 1993 (commencement of 
operations) to January 31, 1994, the following service fees were 
paid by the Prime Money Market Fund:  Class B shares, $127,731 and 
Class C shares, $161.  For the fiscal year ended January 31, 1996, 
the following service fees were paid by Prime Value Money Market 
Fund:  Class B shares, $72,844.42, Class C shares, $0.00, and Class 
E shares, $0.00.  For the fiscal year ended January 31, 1995, the 
following service fees were paid by the Prime Value Money Market 
Fund:  Class B shares, $40,846; no service fees were paid with 
respect to Class C or Class E shares.  For the period February 8, 
1993 (commencement of operations) to January 31, 1994, the 
following service fees were paid by the Prime Value Money Market 
Fund:  Class B shares, $21,438; no service fees were paid with 
respect to Class C shares.  Class E shares were not offered by the 
Funds during the fiscal period ended January 31, 1994.

Expenses

	The Funds' expenses include taxes, interest, fees and salaries 
of the Trust's Trustees and Officers who are not directors, 
officers or employees of the Trust's service contractors, SEC fees, 
state securities qualification fees, costs of preparing and 
printing prospectuses for regulatory purposes and for distribution 
to investors, advisory and administration fees, charges of the 
custodian and of the transfer and dividend disbursing agent, 
Service Organization fees, certain insurance premiums, outside 
auditing and legal expenses, costs of investor reports and 
shareholder meetings and any extraordinary expenses. The Funds also 
pay for brokerage fees and commissions (if any) in connection with 
the purchase and sale of portfolio securities.  The Adviser and 
FDISG have agreed that if, in any fiscal year, the expenses borne 
by a Fund exceed the applicable expense limitations imposed by the 
securities regulations of any state in which shares of that Fund 
are registered or qualified for sale to the public, it will 
reimburse that Fund for any excess to the extent required by such 
regulations in the same proportion that each of their fees bears to 
the Fund's aggregate fees for investment advice and administrative 
services. Unless otherwise required by law, such reimbursement 
would be accrued and paid on the same basis that the advisory and 
administration fees are accrued and paid by that Fund.  To each 
Fund's knowledge, of the expense limitations in effect on the date 
of this Statement of Additional Information, none is more 
restrictive than two and one-half percent (2.5%) of the first 
$30 million of a Fund's average net assets, two percent (2%) of the 
next $70 million of the average net assets and one and one-half 
percent (1.5%) of the remaining average net assets.

ADDITIONAL INFORMATION CONCERNING TAXES

	The following summarizes certain additional tax considerations 
generally affecting a Fund and its investors that are not described 
in the Funds' Prospectuses. No attempt is made to present a 
detailed explanation of the tax treatment of a Fund or its 
investors or possible legislative changes, and the discussion here 
and in the applicable Prospectuses is not intended as a substitute 
for careful tax planning.  Investors should consult their tax 
advisers with specific reference to their own tax situation.

	As stated in each Prospectus, each Fund is treated as a 
separate corporate entity under the Code and qualified as a 
regulated investment company under the Code and intends to so 
qualify in future years. In order to so qualify under the Code for 
a taxable year, a Fund must satisfy the distribution requirement 
described in the Prospectuses, derive at least 90% of its gross 
income for the year from certain qualifying sources, comply with 
certain diversification tests and derive less than 30% of its gross 
income for the year from the sale or other disposition of 
securities and certain other investments held for less than three 
months. Interest (including original issue plus accrued market 
discount) received by a Fund at maturity or disposition of a 
security held for less than three months will not be treated as 
gross income derived from the sale or other disposition of such 
security within the meaning of the 30% requirement. However, any 
income in excess of such interest will be treated as gross income 
from the sale or other disposition of securities for this purpose. 

	A 4% non-deductible excise tax is imposed on regulated 
investment companies that fail currently to distribute an amount 
equal to specified percentages of their ordinary taxable income and 
capital gain net income (excess of capital gains over capital 
losses). Each Fund intends to make sufficient distributions or 
deemed distributions of its ordinary taxable income and any capital 
gain net income prior to the end of each calendar year to avoid 
liability for this excise tax.

	If for any taxable year a Fund does not qualify for tax 
treatment as a regulated investment company, all of that Fund's 
taxable income will be subject to tax at regular corporate rates 
without any deduction for distributions to Fund investors. In such 
event, dividend distributions to investors would be taxable as 
ordinary income to the extent of that Fund's earnings and profits, 
and would be eligible for the dividends received deduction in the 
case of corporate shareholders. 

	Each Fund will be required in certain cases to withhold and 
remit to the U.S. Treasury 31% of taxable dividends or 31% of gross 
proceeds realized upon sale paid to its investors who have failed 
to provide a correct tax identification number in the manner 
required, or who are subject to withholding by the Internal Revenue 
Service for failure properly to include on their return payments of 
taxable interest or dividends, or who have failed to certify to a 
Fund that they are not subject to backup withholding when required 
to do so or that they are "exempt recipients." 

	Although each Fund expects to qualify each year as a 
"regulated investment company" and to be relieved of all or 
substantially all federal income tax, depending upon the extent of 
its activities in states and localities in which its offices are 
maintained, in which its agents or independent contractors are 
located or in which it is otherwise deemed to be conducting 
business, a Fund may be subject to the tax laws of such states or 
localities. In addition, in those states and localities which have 
income tax laws, the treatment of the Fund and its investors under 
such laws may differ from the treatment under federal income tax 
laws. Investors are advised to consult their tax advisers 
concerning the application of state and local taxes. 

DIVIDENDS

	Each Fund's net investment income for dividend purposes 
consists of (i) interest accrued and original issue discount earned 
on that Fund's assets, (ii) plus the amortization of market 
discount and minus the amortization of market premium on such 
assets, (iii) less accrued expenses directly attributable to that 
Fund and the general expenses (e.g., legal, accounting and 
trustees' fees) of the Trust prorated to such Fund on the basis of 
its relative net assets. Any realized short-term capital gains may 
also be distributed as dividends to Fund investors. In addition, a 
Fund's Class B, Class C and Class E shares bear exclusively the 
expense of fees paid to Service Organizations with respect to the 
relevant Class of shares. See "Management of the Funds - Service 
Organizations." 

	The Trust uses its best efforts to maintain the net asset 
value per share of each Fund at $1.00. As a result of a significant 
expense or realized or unrealized loss incurred by a Fund, it is 
possible that a Fund's net asset value per share may fall below 
$1.00. 

ADDITIONAL YIELD INFORMATION

	The "yields" and "effective yields" are calculated separately 
for each class of shares of each Fund and in accordance with the 
formulas prescribed by the SEC.  The seven-day yield for each class 
of shares in a Fund is calculated by determining the net change in 
the value of a hypothetical preexisting account in a Fund having a 
balance of one share of the class involved at the beginning of the 
period, dividing the net change by the value of the account at the 
beginning of the period to obtain the base period return, and 
multiplying the base period return by 365/7. The net change in the 
value of an account in a Fund includes the value of additional 
shares purchased with dividends from the original share and 
dividends declared on the original share and any such additional 
shares, net of all fees charged to all shareholder accounts in 
proportion to the length of the base period and the Fund's average 
account size, but does not include gains and losses or unrealized 
appreciation and depreciation. In addition, the effective 
annualized yield may be computed on a compounded basis (calculated 
as described above) with respect to each class of a Fund's shares 
by adding 1 to the base period return, raising the sum to a power 
equal to 365/7, and subtracting 1 from the result. Similarly, based 
on the calculations described above, 30-day (or one-month) yields 
and effective yields may also be calculated. 

	Based on the fiscal year ended January 31, 1996, the yields 
and effective yields for each of the Funds were as follows:

*estimated yield without fee waivers and/or expense reimbursements.

	Class B, Class C and Class E Shares bear the expenses of fees 
paid to Service Organizations. As a result, at any given time, the 
net yield of Class B, Class C and Class E Shares could be up to 
 .25%, .35% and .15% lower than the net yield of Class A Shares, 
respectively.

	From time to time, in advertisements or in reports to 
investors, a Fund's yield may be quoted and compared to that of 
other money market funds or accounts with similar investment 
objectives and to stock or other relevant indices. For example, the 
yield of the Fund may be compared to the IBC/Donoghue's Money Fund 
Average, which is an average compiled by IBC/Donoghue's MONEY FUND 
REPORT of Holliston, MA 01746, a widely recognized independent 
publication that monitors the performance of money market funds, or 
to the average yields reported by the Bank Rate Monitor from money 
market deposit accounts offered by the 50 leading banks and thrift 
institutions in the top five standard metropolitan statistical 
areas. 

	The Funds' yields will fluctuate, and any quotation of yield 
should not be considered as representative of the future 
performance of the Funds. Since yields fluctuate, yield data cannot 
necessarily be used to compare an investment in a Fund's shares 
with bank deposits, savings accounts and similar investment 
alternatives which often provide an agreed or guaranteed fixed 
yield for a stated period of time. Investors should remember that 
performance and yield are generally functions of the kind and 
quality of the investments held in a portfolio, portfolio maturity, 
operating expenses and market conditions. Any fees charged by banks 
with respect to Customer accounts investing in shares of a Fund 
will not be included in yield calculations; such fees, if charged, 
would reduce the actual yield from that quoted. 

ADDITIONAL DESCRIPTION CONCERNING FUND SHARES

	The Trust does not presently intend to hold annual meetings of 
shareholders except as required by the 1940 Act or other applicable 
law. The law under certain circumstances provides shareholders with 
the right to call for a meeting of shareholders to consider the 
removal of one or more Trustees. To the extent required by law, the 
Trust will assist in shareholder communication in such matters. 

	As stated in the Funds' Prospectuses, holders of shares in a 
Fund in the Trust will vote in the aggregate and not by class on 
all matters, except where otherwise required by law and except that 
only a Fund's Class B, Class C and Class E shares, as the case may 
be, will be entitled to vote on matters submitted to a vote of 
shareholders pertaining to that Fund's arrangements with Service 
Organizations with respect to the relevant Class of shares. (See 
"Management of the Funds - Service Organizations.") Further, 
shareholders of each of the Trust's portfolios will vote in the 
aggregate and not by portfolio except as otherwise required by law 
or when the Board of Trustees determines that the matter to be 
voted upon affects only the interests of the shareholders of a 
particular portfolio. Rule 18f-2 under the 1940 Act provides that 
any matter required to be submitted by the provisions of such Act 
or applicable state law, or otherwise, to the holders of the 
outstanding securities of an investment company such as the Trust 
shall not be deemed to have been effectively acted upon unless 
approved by the holders of a majority of the outstanding shares of 
each portfolio affected by the matter. Rule 18f-2 further provides 
that a portfolio shall be deemed to be affected by a matter unless 
it is clear that the interests of each portfolio in the matter are 
identical or that the matter does not affect any interest of the 
portfolio. Under the Rule, the approval of an investment advisory 
agreement or any change in a fundamental investment policy would be 
effectively acted upon with respect to a portfolio only if approved 
by the holders of a majority of the outstanding voting securities 
of such portfolio. However, the Rule also provides that the 
ratification of the selection of independent auditors, the approval 
of principal underwriting contracts and the election of Trustees 
are not subject to the separate voting requirements and may be 
effectively acted upon by shareholders of the investment company 
voting without regard to portfolio.

FINANCIAL STATEMENTS

	The Trust's Annual Report for the fiscal year ended January 
31, 1995 and its Semi-Annual Report for the six months ended July 
31, 1995 are incorporated into this Statement of Additional 
Information by reference in their entirety.

MISCELLANEOUS

Shareholder Vote

	As used in this Statement of Additional Information and the 
Funds' Prospectuses, a "majority of the outstanding shares" of a 
Fund or of any other portfolio means the lesser of (1) 67% of that 
Fund's shares (irrespective of class) or of the portfolio 
represented at a meeting at which the holders of more than 50% of 
the outstanding shares of that Fund or portfolio are present in 
person or by proxy, or (2) more than 50% of the outstanding shares 
of a Fund (irrespective of class) or of the portfolio. 

Shareholder and Trustee Liability

	The Trust is organized as a "business trust" under the laws of 
the Commonwealth of Massachusetts. Shareholders of such a trust 
may, under certain circumstances, be held personally liable (as if 
they were partners) for the obligations of the trust. The 
Declaration of Trust of the Trust provides that shareholders shall 
not be subject to any personal liability for the acts or 
obligations of the Trust and that every note, bond, contract, order 
or other undertaking made by the Trust shall contain a provision to 
the effect that the shareholders are not personally liable 
thereunder. The Declaration of Trust provides for indemnification 
out of the trust property of a Fund of any shareholder of the Fund 
held personally liable solely by reason of being or having been a 
shareholder and not because of any acts or omissions or some other 
reason. The Declaration of Trust also provides that the Trust 
shall, upon request, assume the defense of any claim made against 
any shareholder for any act or obligation of the Trust and satisfy 
any judgment thereon. Thus, the risk of a shareholder incurring 
financial loss beyond the amount invested in a Fund on account of 
shareholder liability is limited to circumstances in which the Fund 
itself would be unable to meet its obligations. 

	The Trust's Declaration of Trust provides further that no 
Trustee of the Trust shall be personally liable for or on account 
of any contract, debt, tort, claim, damage, judgment or decree 
arising out of or connected with the administration or preservation 
of the trust estate or the conduct of any business of the Trust, 
nor shall any Trustee be personally liable to any person for any 
action or failure to act except by reason of bad faith, willful 
misfeasance, gross negligence in performing duties, or by reason of 
reckless disregard for the obligations and duties as Trustee. It 
also provides that all persons having any claim against the 
Trustees or the Trust shall look solely to the trust property for 
payment.  With the exceptions stated, the Declaration of Trust 
provides that a Trustee is entitled to be indemnified against all 
liabilities and expenses reasonably incurred in connection with the 
defense or disposition of any proceeding in which the Trustee may 
be involved or may be threatened with by reason of being or having 
been a Trustee, and that the Trustees have the power, but not the 
duty, to indemnify officers and employees of the Trust unless such 
persons would not be entitled to indemnification if they were in 
the position of Trustee.


APPENDIX

DESCRIPTION OF RATINGS

Commercial Paper Ratings

	Standard & Poor's, a division of The McGraw-Hill Companies 
("Standard & Poor's") commercial paper rating is a current assessment 
of the likelihood of timely payment of debt considered short-term in 
the relevant market. The following summarizes the two highest rating 
categories used by Standard & Poor's for commercial paper: 

	"A-1" - Issue's degree of safety regarding timely payment is 
strong. Those issues determined to possess extremely strong safety 
characteristics are denoted "A-1+." 

	"A-2" - Issue's capacity for timely payment is satisfactory. 
However, the relative degree of safety is not as high as for issues 
designated "A-1." 

	Moody's short-term debt ratings are opinions of the ability of 
issuers to repay punctually senior debt obligations which have an 
original maturity not exceeding one year. The following summarizes 
the two highest rating categories used by Moody's for commercial 
paper: 

	"Prime-1" - Issuer or related supporting institutions are 
considered to have a superior ability for repayment of senior 
short-term debt obligations. Principal repayment capacity will 
normally be evidenced by the following characteristics: leading 
market positions in well-established industries; high rates of return 
on funds employed; conservative capitalization structures with 
moderate reliance on debt and ample asset protection; broad margins 
in earning coverage of fixed financial charges and high internal cash 
generation; and well-established access to a range of financial 
markets and assured sources of alternate liquidity. 

	"Prime-2" - Issuer or related supporting institutions are 
considered to have a strong ability for repayment of senior 
short-term debt obligations. This will normally be evidenced by many 
of the characteristics cited above but to a lesser degree. Earnings 
trends and coverage ratios, while sound, will be more subject to 
variation. Capitalization characteristics, while still appropriate, 
may be more affected by external conditions. Ample alternative 
liquidity is maintained. 

	The two highest rating categories of Duff & Phelps for 
investment grade commercial paper are "D-1" and "D-2." Duff & Phelps 
employs three designations, "D-1+," "D-1" and "D-1-," within the 
highest rating category. The following summarizes the two highest 
rating categories used by Duff & Phelps for commercial paper: 

	"D-1+" - Debt possesses highest certainty of timely payment. 
Short-term liquidity, including internal operating factors and/or 
access to alternative sources of funds, is outstanding, and safety is 
just below risk-free U.S. Treasury short-term obligations. 

	"D-1" - Debt possesses very high certainty of timely payment. 
Liquidity factors are excellent and supported by good fundamental 
protection factors. Risk factors are minor. 

	"D-1-" - Debt possesses high certainty of timely payment. 
Liquidity factors are strong and supported by good fundamental 
protection factors. Risk factors are very small. 

	"D-2" - Debt possesses good certainty of timely payment. 
Liquidity factors and company fundamentals are sound. Although 
ongoing funding needs may enlarge total financing requirements, 
access to capital markets is good. Risk factors are small. 

	Fitch short-term ratings apply to debt obligations that are 
payable on demand or have original maturities of generally up to 
three years. The two highest rating categories of Fitch for 
short-term obligations are "F-1" and "F-2." Fitch employs two 
designations, "F-1+" and "F-1," within the highest rating category. 
The following summarizes some of the rating categories used by Fitch 
for short-term obligations: 

	"F-1+" - Securities possess exceptionally strong credit quality. 
Issues assigned this rating are regarded as having the strongest 
degree of assurance for timely payment. 

	"F-1" - Securities possess very strong credit quality. Issues 
assigned this rating reflect an assurance of timely payment only 
slightly less in degree than issues rated "F-1+." 

	"F-2" - Securities possess good credit quality. Issues carrying 
this rating have a satisfactory degree of assurance for timely 
payment, but the margin of safety is not as great as the "F-1+" and 
"F-1" categories. 

	Fitch may also use the symbol "LOC" with its short-term ratings 
to indicate that the rating is based upon a letter of credit issued 
by a commercial bank. 

	Thomson BankWatch short-term ratings assess the likelihood of an 
untimely payment of principal or interest of debt having a maturity 
of one year or less.  The following summarizes the two highest 
ratings used by Thomson BankWatch: 

	"TBW-1" - This designation represents Thomson BankWatch's 
highest rating category and indicates a very high degree of 
likelihood that principal and interest will be paid on a timely 
basis. 

	"TBW-2" - This designation indicates that while the degree of 
safety regarding timely payment of principal and interest is strong, 
the relative degree of safety is not as high as for issues rated 
"TBW-1." 

	IBCA assesses the investment quality of unsecured debt with an 
original maturity of less than one year which is issued by bank 
holding companies and their principal bank subsidiaries. The highest 
rating category of IBCA for short-term debt is "A." IBCA employs two 
designations, "A1+" and "A1," within the highest rating category. The 
following summarizes the two highest rating categories used by IBCA 
for short-term debt ratings: 

	"A1" - Obligations are supported by the highest capacity for 
timely repayment.  Where issues possess a particularly strong credit 
feature a rating of "A1+" is assigned.

	"A2" - Obligations are supported by a good capacity for timely 
repayment.



Long-Term Debt Ratings

	The following summarizes the ratings used by Standard & Poor's 
for long-term debt: 

	"AAA" - This designation represents the highest rating assigned 
by Standard & Poor's to a debt obligation and indicates an extremely 
strong capacity to pay interest and repay principal. 

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

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

	"BBB" - Debt is regarded as having an adequate capacity to pay 
interest and repay principal.  Whereas such issues normally exhibit 
adequate protection parameters, adverse economic conditions or 
changing circumstances are more likely to lead to a weakened capacity 
to pay interest and repay principal for debt in this category than in 
higher-rated categories.

	"BB," "B," "CCC," "CC," and "C" - Debt that possesses one of 
these ratings is regarded as having predominantly speculative 
characteristics with respect to capacity to pay interest and repay 
principal.  "BB" indicates the least degree of speculation and "CCC" 
the highest degree of speculation.  While such debt will likely have 
some quality and protective characteristics, these are outweighed by 
large uncertainties or major risk exposures to adverse conditions.

	"CI" - This rating is reserved for income bonds on which no 
interest is being paid.

	"D" - Debt is in payment default.  This rating is also used upon 
the filing of a bankruptcy petition if debt service payments are 
jeopardized.

	PLUS (+) or MINUS (-) - The rating of "AA" may be modified by 
the addition of a plus or minus sign to show relative standing within 
this rating category. 

	The following summarizes the ratings used by Moody's for 
long-term debt: 

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

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

	"A" - Bonds possess many favorable investment attributes and are 
to be considered as upper medium grade obligations.  Factors giving 
security to principal and interest are considered adequate but 
elements may be present which suggest a susceptibility to impairment 
sometime in the future.

	"Baa" - Bonds considered medium-grade obligations, i.e., they 
are neither highly protected nor poorly secured. Interest payments 
and principal security appear adequate for the present but certain 
protective elements may be lacking or may be characteristically 
unreliable over any great length of time. Such bonds lack outstanding 
investment characteristics and in fact have speculative 
characteristics as well.

	"Ba," "B," "Caa," "Ca," and "C" - Bonds that possess one of 
these ratings provide questionable protection of interest and 
principal ("Ba" indicates some speculative elements; "B" indicates a 
general lack of characteristics of desirable investment; "Caa" 
represents a poor standing; "Ca" represents obligations which are 
speculative in a high degree; and "C" represents the lowest rated 
class of bonds). "Caa," "Ca" and "C" bonds may be in default.

	Con. (---) - Municipal Bonds for which the security depends upon 
the completion of some act or the fulfillment of some condition are 
rated conditionally. These are bonds secured by (a) earnings of 
projects under construction, (b) earnings of projects unseasoned in 
operation experience, (c) rentals which begin when facilities are 
completed, or (d) payments to which some other limiting condition 
attaches. Parenthetical rating denotes probable credit stature upon 
completion of construction or elimination of basis of condition. 

	Moody's applies numerical modifiers 1, 2 and 3 in generic 
classification of "Aa" in its corporate bond rating system. The 
modifier 1 indicates that the company ranks in the higher end of its 
generic rating category; the modifier 2 indicates a mid-range 
ranking; and the modifier 3 indicates that the company ranks at the 
lower end of its generic rating category. 

	Those municipal bonds in the "Aa" to "B" groups which Moody's 
believes posses the strongest investment attributes are designated by 
the symbols "Aa1," "A1," "Baa1," "Ba1," and "B1."

	The following summarizes the ratings used by Duff & Phelps for 
long-term debt: 

	"AAA" - Debt is considered to be of the highest credit quality. 
The risk factors are negligible, being only slightly more than for 
risk-free U.S. Treasury debt. 

	"AA" - Debt is considered of high credit quality. Protection 
factors are strong. Risk is modest but may vary slightly from time to 
time because of economic conditions. 

	"A" - Debt possesses protection factors which are average but 
adequate.  However, risk factors are more variable and greater in 
periods of economic stress.

	"BBB" - Debt possesses below average Protection factors but such 
protection factors are still considered sufficient for prudent 
investment.  Considerable variability in risk is present during 
economic cycles.

	"BB," "B," "CCC," "DD," and "DP" - Debt that possesses one of 
these ratings is considered to be below investment grade.  Although 
below investment grade, debt rated "BB" is deemed likely to meet 
obligations when due.  Debt rated "B" possesses the risk that 
obligations will not be met when due. Debt rated "CCC" is well below 
investment grade and has considerable uncertainty as to timely 
payment of principal, interest or preferred dividends.  Debt rated 
"DD" is a defaulted debt obligation, and the rating "DP" represents 
preferred stock with dividend averages.

	 To provide more detailed indications of credit quality, the 
"AA," "A," "BBB," "BB" and "B" ratings may be modified by the 
addition of a plus (+) or minus (-) sign to show relative standing 
within these major rating categories. 

	The following summarizes the ratings used by Fitch for bonds: 

	"AAA" - Bonds considered to be investment grade and of the 
highest credit quality. The obligor has an exceptionally strong 
ability to pay interest and repay principal, which is unlikely to be 
affected by reasonably foreseeable events. 

	"AA" - Bonds considered to be investment grade and of very high 
credit quality. The obligor's ability to pay interest and repay 
principal is very strong, although not quite as strong as bonds rated 
"AAA." Because bonds rated in the "AAA" and "AA" categories are not 
significantly vulnerable to foreseeable future developments, 
short-term debt of these issuers is generally rated "F-1+." 

	"A" - Bonds considered to be investment grade and of high credit 
quality.  The obligor's ability to pay interest and repay principal 
is considered to be strong, but may be more vulnerable to adverse 
changes in economic conditions and circumstances than bonds with 
higher ratings.

	"BBB" - Bonds considered to be investment grade and of 
satisfactory credit quality.  The obligor's ability to pay interest 
and repay principal is considered to be adequate.  Adverse changes in 
economic conditions and circumstances, however, are more likely to 
have an adverse impact on these bonds, and therefore, impair timely 
payment.  The likelihood that the ratings of these bonds will fall 
below investment grade is higher than for bonds with higher ratings.

	"BB," "B," "CCC," "CC," "C," "DDD," "DD," and "D" -Bonds that 
possess one of these ratings are considered by Fitch to be 
speculative investments.  The ratings "BB" to "C" represent Fitch's 
assessment of the likelihood of timely payment of principal and 
interest in accordance with the terms of obligation for bond issues 
not in default.  For defaulted bonds, the rating "DDD" to "D" is an 
assessment that bonds should be valued on the basis of the ultimate 
recovery value in liquidation or reorganization of the obligor.

	To provide more detailed indications of credit quality, the 
Fitch ratings from and including "AA" to "C" may be modified by the 
addition of a plus (+) or minus (-) sign to show relative standing 
within these major rating categories. 

	Thomson BankWatch assesses the likelihood of an untimely 
repayment of principal or interest over the term to maturity of 
long-term debt and preferred stock which are issued by United States 
commercial banks, thrifts and non-bank banks; non-United States 
banks; and broker-dealers. The following summarizes the two highest 
rating categories used by Thomson BankWatch for long-term debt 
ratings: 

	"AAA" - This designation represents the highest category 
assigned by Thomson BankWatch to long-term debt and indicates that 
the ability to repay principal and interest on a timely basis is very 
high. 

	"AA" - This designation indicates a superior ability to repay 
principal and interest on a timely basis with limited incremental 
risk versus issues rated in the highest category. 

	"A" - This designation indicates the ability to repay principal 
and interest is strong.  Issues rated "A" could be more vulnerable to 
adverse developments (both internal and external) than obligations 
with higher ratings.

	PLUS (+) or MINUS (-) - The ratings may include a plus or minus 
sign designation which indicates where within the respective category 
the issue is placed. 

	IBCA assesses the investment quality of unsecured debt with an 
original maturity of more than one year which is issued by bank 
holding companies and their principal bank subsidiaries. The 
following summarizes the two highest rating categories used by IBCA 
for long-term debt ratings: 

	"AAA" - Obligations for which there is the lowest expectation of 
investment risk. Capacity for timely repayment of principal and 
interest is substantial such that adverse changes in business, 
economic or financial conditions are unlikely to increase investment 
risk significantly. 

	"AA" - Obligations for which there is a very low expectation of 
investment risk. Capacity for timely repayment of principal and 
interest is substantial. Adverse changes in business, economic or 
financial conditions may increase investment risk albeit not very 
significantly. 

	"A" - Obligations for which there is a low expectation of 
investment risk.  Capacity for timely repayment of principal and 
interest is strong, although adverse changes in business economic or 
financial conditions may lead to increased investment risk.

	IBCA may append a rating of plus (+) or minus (-) to a rating to 
denote relative status within these rating categories. 

Municipal Note Ratings

	A Standard & Poor's rating reflects the liquidity factors and 
market access risks unique to notes due in three years or less. The 
following summarizes the two highest rating categories used by 
Standard & Poor's Corporation for municipal notes: 

	"SP-1" - The issuers of these municipal notes exhibit strong 
capacity to pay principal and interest. Those issues determined to 
possess a very strong capacity to pay are given a plus (+) 
designation. 

	"SP-2" - The issuers of these municipal notes exhibit 
satisfactory capacity to pay principal and interest, with some 
vulnerability to adverse financial and economic changes over the term 
of the notes. 

	Moody's ratings for state and municipal notes and other 
short-term loans are designated Moody's Investment Grade ("MIG"). 
Such ratings recognize the differences between short-term credit risk 
and long-term risk. A short-term rating may also be assigned on an 
issue having a demand feature.  Such ratings will be designated as 
"VMIG."  The following summarizes the two highest ratings used by 
Moody's Investors Service, Inc. for short-term notes: 

	"MIG-1"/"VMIG-1" - This designation denotes best quality.  There 
is strong protection by established cash flows, superior liquidity 
support or demonstrated broad-based access to the market for 
refinancing. 

	"MIG-2"/"VMIG-2" - This designation denotes high quality.  
Margins of protection are ample although not so large as in the 
preceding group. 

	Duff & Phelps and Fitch use the short-term ratings described 
under Commercial Paper Ratings for municipal notes.

THE TRUST

	Lehman Brothers Institutional Funds Group Trust (the "Trust") is 
an open-end management investment company.  The Trust currently 
includes a family of portfolios, three of which are Government 
Obligations Money Market, Cash Management Fund and Treasury 
Instruments Money Market Fund II (individually, a "Fund"; 
collectively, the "Funds"). 

	The securities held by Government Obligations Money Market Fund 
consist of obligations issued or guaranteed by the U.S. Government, 
its agencies or instrumentalities and repurchase agreements relating 
to such obligations. Securities held by Cash Management Fund consist 
of U.S. Treasury bills, notes and obligations issued or guaranteed as 
to principal and interest by the U.S. Government, its agencies or 
instrumentalities and repurchase agreements relating to such 
obligations. Securities held by Treasury Instruments Money Market 
Fund II are limited to U.S. Treasury bills, notes and other direct 
obligations of the U.S. Treasury and repurchase agreements relating 
to direct Treasury obligations. Although all three Funds have the 
same Investment Adviser, Lehman Brothers Global Asset Management, 
Inc. (the "Adviser"), and have comparable investment objectives, 
their yields normally will differ due to their differing cash flows 
and differences in the specific portfolio securities held. 

	THIS STATEMENT OF ADDITIONAL INFORMATION AND THE FUNDS' 
PROSPECTUSES RELATE PRIMARILY TO THE FUNDS AND DESCRIBE ONLY THE 
INVESTMENT OBJECTIVE AND POLICIES, OPERATIONS, CONTRACTS AND OTHER 
MATTERS RELATING TO THE FUNDS. INVESTORS WISHING TO OBTAIN SIMILAR 
INFORMATION REGARDING THE TRUST'S OTHER PORTFOLIOS MAY OBTAIN 
INFORMATION DESCRIBING THEM BY CONTACTING LEHMAN BROTHERS AT 1-
800-368-5556.

INVESTMENT OBJECTIVE AND POLICIES

	As stated in the Funds' Prospectuses, the investment objective 
of the Funds is current income with liquidity and security of 
principal. The following policies supplement the description in the 
Prospectuses of the investment objectives and policies of the Funds. 

	The Funds are managed to provide stability of capital while 
achieving competitive yields. The Adviser intends to follow a 
value-oriented, research-driven and risk-averse investment strategy, 
engaging in a full range of economic, strategic, credit and 
market-specific analyses in researching potential investment 
opportunities. 

Portfolio Transactions

	Subject to the general control of the Trust's Board of Trustees, 
the Adviser is responsible for, makes decisions with respect to and 
places orders for all purchases and sales of portfolio securities for 
the Funds. Purchases of portfolio securities are usually principal 
transactions without brokerage commissions. In making portfolio 
investments, the Adviser seeks to obtain the best net price and the 
most favorable execution of orders. To the extent that the execution 
and price offered by more than one dealer are comparable, the Adviser 
may, in its discretion, effect transactions in portfolio securities 
with dealers who provide the Trust with research advice or other 
services. Although the Funds will not seek profits through short-term 
trading, the Adviser may, on behalf of the Funds, dispose of any 
portfolio security prior to its maturity if it believes such 
disposition is advisable. 

	Investment decisions for the Funds are made independently from 
those for other investment company portfolios advised by the Adviser.  
Such other investment company portfolios may invest in the same 
securities as the Funds. When purchases or sales of the same security 
are made at substantially the same time on behalf of such other 
investment company portfolios, transactions are averaged as to price, 
and available investments allocated as to amount, in a manner which 
the Adviser believes to be equitable to each portfolio, including the 
Funds. In some instances, this investment procedure may adversely 
affect the price paid or received by the Funds or the size of the 
position obtained for the Funds. To the extent permitted by law, the 
Adviser may aggregate the securities to be sold or purchased for the 
Funds with those to be sold or purchased for such other investment 
company portfolios in order to obtain best execution. 

	The Funds will not execute portfolio transactions through, 
acquire portfolio securities issued by, make savings deposits in, or 
enter into repurchase agreements with Lehman Brothers or the Adviser 
or any affiliated person (as such term is defined in the Investment 
Company Act of 1940, as amended (the "1940 Act"), of any of them, 
except to the extent permitted by the Securities and Exchange 
Commission (the "SEC").  In addition, with respect to such 
transactions, securities, deposits and agreements, the Funds will not 
give preference to Service Organizations with which a Fund enters 
into agreements.  (See the Prospectuses, "Management of the Fund-
Service Organizations").

	The Funds may seek profits through short-term trading. The 
Funds' annual portfolio turnover rates will be relatively high, but 
brokerage commissions are normally not paid on money market 
instruments and the Funds' portfolio turnover is not expected to have 
a material effect on the net incomes of the Funds. The portfolio 
turnover rate for each of the Funds is expected to be zero for 
regulatory reporting purposes. 

Additional Information on Investment Practices

	The repurchase price under the repurchase agreements described 
in the Funds' Prospectuses generally equals the price paid by a Fund 
plus interest negotiated on the basis of current short-term rates 
(which may be more or less than the rate on the securities underlying 
the repurchase agreement). Securities subject to repurchase 
agreements will be held by the Funds' Custodian, sub-custodian or in 
the Federal Reserve/Treasury book-entry system. Repurchase agreements 
are considered to be loans by the Funds under the 1940 Act. 

	Whenever the Funds enter into reverse repurchase agreements as 
described in their Prospectuses, they will place in a segregated 
custodian account liquid assets having a value equal to the 
repurchase price (including accrued interest) and will subsequently 
monitor the account to ensure such equivalent value is maintained. 
Reverse repurchase agreements are considered to be borrowings by the 
Funds under the 1940 Act. 

	As stated in the Funds' Prospectuses, the Funds may purchase 
securities on a "when-issued" basis (i.e., for delivery beyond the 
normal settlement date at a stated price and yield). When a Fund 
agrees to purchase when-issued securities, its Custodian will set 
aside cash or liquid portfolio securities equal to the amount of the 
commitment in a separate account. Normally, the Custodian will set 
aside portfolio securities to satisfy a purchase commitment, and in 
such a case such Fund may be required subsequently to place 
additional assets in the separate account in order to ensure that the 
value of the account remains equal to the amount of such Fund's 
commitment. It may be expected that a Fund's net assets will 
fluctuate to a greater degree when it sets aside portfolio securities 
to cover such purchase commitments than when it sets aside cash. 
Because the Funds will set aside cash or liquid assets to satisfy 
their respective purchase commitments in the manner described, such a 
Fund's liquidity and ability to manage its portfolio might be 
affected in the event its commitments to purchase when-issued 
securities ever exceeded 25% of the value of its assets. The Funds do 
not intend to purchase when-issued securities for speculative 
purposes but only in furtherance of their investment objectives. The 
Funds reserve the right to sell the securities before the settlement 
date if it is deemed advisable. 

	When a Fund engages in when-issued transactions, it relies on 
the seller to consummate the trade. Failure of the seller to do so 
may result in a Fund incurring a loss or missing an opportunity to 
obtain a price considered to be advantageous. 

	Each Fund has the ability to lend securities from its portfolio 
to brokers, dealers and other financial organizations. There is no 
investment restriction on the amount of securities that may be 
loaned. A Fund may not lend its portfolio securities to Lehman 
Brothers or its affiliates without specific authorization from the 
SEC. Loans of portfolio securities by a Fund will be collateralized 
by cash, letters of credit or securities issued or guaranteed by the 
U.S. Government or its agencies which will be maintained at all times 
in an amount equal to at least 100% of the current market value of 
the loaned securities (and will be marked to market daily). From time 
to time, a Fund may return a part of the interest earned from the 
investment of collateral received for securities loaned to the 
borrower and/or a third party, which is unaffiliated with the Fund or 
with Lehman Brothers, and which is acting as a "finder." With respect 
to loans by the Funds of their portfolio securities, the Funds would 
continue to accrue interest on loaned securities and would also earn 
income on loans. Any cash collateral received by the Funds in 
connection with such loans would be invested in short-term U.S. 
Government obligations. 

	The Funds may invest in mortgage backed securities issued by 
U.S. Government agencies or instrumentalities consisting of mortgage 
pass-through securities or collateralized mortgage obligations 
("CMOs").  Mortgage pass-through securities in which the Funds may 
invest represent a partial ownership interest in a pool of 
residential mortgage loans and are issued or guaranteed by the 
Government National Mortgage Association ("GNMA"), the Federal 
National Mortgage Association ("FNMA") and the Federal Home Loan 
Mortgage Corporation ("FHLMC").  CMOs are debt obligations 
collateralized by mortgage loans or mortgage pass-through securities 
(collateral collectively referred to as "Mortgage Assets").  CMOs in 
which the Funds may invest are issued by GNMA, FNMA and FHLMC.  In a 
CMO, a series of bonds or certificates are usually issued in multiple 
classes.  Each class of CMOs, often referred to as a "tranche," is 
issued at a specific fixed or floating coupon rate and has a stated 
maturity or final distribution date.  Principal prepayments on the 
Mortgage Assets may cause the CMOs to be retired substantially 
earlier than their stated maturities or final distribution dates, 
resulting in a loss of all or part of the premium if any has been 
paid.  Interest is paid or accrues on all classes of the CMOs on a 
monthly, quarterly or semiannual basis.  The Funds expect that 
mortgage backed securities will only be purchased in connection with 
repurchase transactions.

Investment Limitations

	The Funds' Prospectuses summarize certain investment limitations 
that may not be changed without the affirmative vote of the holders 
of a "majority of the outstanding shares" of the respective Fund (as 
defined below under "Miscellaneous"). Investment limitations numbered 
1 through 7 may not be changed without such a vote of shareholders; 
investment limitations 8 through 13 may be changed by a vote of the 
Trust's Board of Trustees at any time. 

	A Fund may not: 

 1.	Purchase the securities of any issuer if as a result more than 
5% of the value of the Fund's assets would be invested in the 
securities of such issuer, except that 25% of the value of the Fund's 
assets may be invested without regard to this 5% limitation and 
provided that there is no limitation with respect to investments in 
U.S. Government securities. 

 2.	Borrow money except that the Fund may (i) borrow money for 
temporary or emergency purposes (not for leveraging or investment) 
from banks or, subject to specific authorization by the SEC, from 
funds advised by the Adviser or an affiliate of the Adviser, and (ii) 
engage in reverse repurchaase agreements, provided that (i) and (ii) 
in combination do not exceed one-third of the value of the particular 
Fund's total assets (including the amount borrowed) less liabilities 
(other than borrowings).  A Fund may not mortgage, pledge or 
hypothecate its assets except in connection with such borrowings and 
reverse repurchase agreements and then only in amounts not exceeding 
one-third of the value of the particular Fund's total assets.  
Additional investments will not be made when borrowings exceed 5% of 
the Fund's assets.

 3.	Make loans except that a Fund may (i) purchase or hold debt 
obligations in accordance with its investment objective and policies, 
(ii) may enter into repurchase agreements for securities, (iii) may 
lend portfolio securities and (iv) subject to specific authorization 
by the SEC, lend money to other funds advised by the Adviser or an 
affiliate of the Adviser.

 4.	Act as an underwriter, except insofar as the Fund may be deemed 
an underwriter under applicable securities laws in selling portfolio 
securities. 

 5.	Purchase or sell real estate or real estate limited partnerships 
except that the Fund may invest in securities secured by real estate 
or interests therein. 

 6.	Purchase or sell commodities or commodity contracts, or invest 
in oil, gas or mineral exploration or development programs or in 
mineral leases. 

 7.	Purchase any securities which would cause 25% or more of the 
value of its total assets at the time of purchase to be invested in 
the securities of issuers conducting their principal business 
activities in the same industry, provided that there is no limitation 
with respect to investments in U.S. Government securities. 

 8.	Knowingly invest more than 10% of the value of the Fund's assets 
in securities that may be illiquid because of legal or contractual 
restrictions on resale or securities for which there are no readily 
available market quotations. 

 9.	Purchase securities on margin, make short sales of securities or 
maintain a short position. 

10.	Write or sell puts, calls, straddles, spreads or combinations 
thereof. 

11.	Invest in securities if as a result the Fund would then have 
more than 15% (or such lesser amount as set by state securities laws) 
of its total assets in securities of companies (including 
predecessors) with less than three years of continuous operation. 

12.	Purchase securities of other investment companies except as 
permitted under the 1940 Act or in connection with a merger, 
consolidation, acquisition or reorganization. 

13.	Invest in warrants. 

ADDITIONAL PURCHASE AND REDEMPTION INFORMATION

In General

	Information on how to purchase and redeem a Fund's shares, 
including the timing of placing a purchase and redemption order, is 
included in its Prospectus. The issuance of shares is recorded on the 
books of the Funds, and share certificates are not issued.

	The regulations of the Comptroller of the Currency (the 
"Comptroller") provide that funds held in a fiduciary capacity by a 
national bank approved by the Comptroller to exercise fiduciary 
powers must be invested in accordance with the instrument 
establishing the fiduciary relationship and local law. The Trust 
believes that the purchase of Fund shares by such national banks 
acting on behalf of their fiduciary accounts is not contrary to 
applicable regulations if consistent with the particular account and 
proper under the law governing the administration of the account. 

	Conflict of interest restrictions may apply to an institution's 
receipt of compensation paid by the Funds on fiduciary funds that are 
invested in a Fund's Class B, Class C or Class E shares. 
Institutions, including banks regulated by the Comptroller and 
investment advisers and other money managers subject to the 
jurisdiction of the SEC, the Department of Labor or state securities 
commissions, should consult their legal advisers before investing 
fiduciary funds in a Fund's Class B, Class C or Class E shares. 

	Under the 1940 Act, the Funds may suspend the right of 
redemption or postpone the date of payment upon redemption for any 
period during which the New York Stock Exchange ("NYSE") is closed, 
other than customary weekend and holiday closings, or during which 
trading on the NYSE is restricted, or during which (as determined by 
the SEC by rule or regulation) an emergency exists as a result of 
which disposal or valuation of portfolio securities is not reasonably 
practicable, or for such other periods as the SEC may permit. (The 
Funds may also suspend or postpone the recordation of the transfer of 
their shares upon the occurrence of any of the foregoing conditions.)  
	In addition, the Funds may redeem shares involuntarily in 
certain other instances if the Board of Trustees determines that 
failure to redeem may have material adverse consequences to a Fund's 
investors in general. Each Fund is obligated to redeem shares solely 
in cash up to $250,000 or 1% of the Fund's net asset value, whichever 
is less, for any one investor within a 90-day period. Any redemption 
beyond this amount will also be in cash unless the Board of Trustees 
determines that conditions exist which make payment of redemption 
proceeds wholly in cash unwise or undesirable. In such a case, the 
Fund may make payment wholly or partly in readily marketable 
securities or other property, valued in the same way as the Fund 
determines net asset value. See "Net Asset Value" below for an 
example of when such redemption or form of payment might be 
appropriate. Redemption in kind is not as liquid as a cash 
redemption. Investors who receive a redemption in kind may incur 
transaction costs if they sell such securities or property, and may 
receive less than the redemption value of such securities or property 
upon sale, particularly where such securities are sold prior to 
maturity. 

	Any institution purchasing shares on behalf of separate accounts 
will be required to hold the shares in a single nominee name (a 
"Master Account"). Institutions investing in more than one of the 
Trust's portfolios or classes of shares must maintain a separate 
Master Account for each portfolio and class of shares. Sub-accounts 
may be established by name or number either when the Master Account 
is opened or later. 

Net Asset Value

	Each Fund's net asset value per share is calculated separately 
for each class by dividing the total value of the assets belonging to 
a Fund attributable to a class, less the value of any class-specific 
liabilities charged to such Fund, by the total number of that Fund's 
shares of such class outstanding.  "Assets belonging to" a Fund 
consist of the consideration received upon the issuance of shares 
together with all income, earnings, profits and proceeds derived from 
the investment thereof, including any proceeds from the sale, 
exchange or liquidation of such investments, any funds or payments 
derived from any reinvestment of such proceeds, and a portion of any 
general assets of the Trust not belonging to a particular Fund. 
Assets belonging to a particular Fund are charged with the direct 
liabilities of that Fund and with a share of the general liabilities 
of the Trust allocated in proportion to the relative net assets of 
such Fund and the Trust's other portfolios. Determinations made in 
good faith and in accordance with generally accepted accounting 
principles by the Board of Trustees as to the allocations of any 
assets or liabilities with respect to a Fund are conclusive. 

	As stated in the Funds' Prospectuses, in computing the net asset 
value of shares of the Funds for purposes of sales and redemptions, 
the Funds use the amortized cost method of valuation. Under this 
method, the Funds value each of their portfolio securities at cost on 
the date of purchase and thereafter assume a constant proportionate 
amortization of any discount or premium until maturity of the 
security. As a result, the value of a portfolio security for purposes 
of determining net asset value normally does not change in response 
to fluctuating interest rates. While the amortized cost method 
provides certainty in portfolio valuation, it may result in 
valuations for the Funds' securities which are higher or lower than 
the market value of such securities. 

	In connection with their use of amortized cost valuation, each 
of the Funds limits the dollar-weighted average maturity of its 
portfolio to not more than 90 days and does not purchase any 
instrument with a remaining maturity of more than thirteen months 
(with certain exceptions) (12 months in the case of Government 
Obligations Money Market Fund). In determining the average weighted 
portfolio maturity of each Fund, a variable rate obligation that is 
issued or guaranteed by the U.S. Government, or an agency or 
instrumentality thereof, is deemed to have a maturity equal to the 
period remaining until the obligation's next interest rate 
adjustment. The Trust's Board of Trustees has also established 
procedures, pursuant to rules promulgated by the SEC,  that are 
intended to stabilize the net asset value per share of each Fund for 
purposes of sales and redemptions at $1.00. Such procedures include 
the determination at such intervals as the Board deems appropriate, 
of the extent, if any, to which each Fund's net asset value per share 
calculated by using available market quotations deviates from $1.00 
per share. In the event such deviation exceeds 1/2 of 1% with respect 
to a Fund, the Board will promptly consider what action, if any, 
should be initiated. If the Board believes that the amount of any 
deviation from the $1.00 amortized cost price per share of a Fund may 
result in material dilution or other unfair results to investors or 
existing investors, it will take such steps as it considers 
appropriate to eliminate or reduce to the extent reasonably 
practicable any such dilution or unfair results. These steps may 
include selling portfolio instruments prior to maturity; shortening 
the Fund's average portfolio maturity; withholding or reducing 
dividends; redeeming shares in kind; or utilizing a net asset value 
per share determined by using available market quotations.

Distributor

	Lehman Brothers acts as the Distributor of each Funds' shares.  
Lehman Brothers, located at 3 World Financial Center, New York, New 
York 10285, is a wholly-owned subsidiary of Lehman Brothers Holdings 
Inc. ("Holdings").  As of December 31, 1995, FMR Corp. beneficially 
owned approximately 11.7%, Nippon Life Insurance Company beneficially 
owned approximately 5.0% and Prudential Asset Management beneficially 
owned approximately 5.0% of the outstanding voting securities of 
Holdings.  Each Fund's shares are sold on a continuous basis by 
Lehman Brothers.  The Distributor pays the cost of printing and 
distributing prospectuses to persons who are not investors of the 
Funds (excluding preparation and printing expenses necessary for the 
continued registration of a Fund's shares) and of preparing, printing 
and distributing all sales literature. No compensation is payable by 
the Funds to Lehman Brothers for its distribution services. 

	Lehman Brothers is comprised of several major operating business 
units. Lehman Brothers Institutional Funds Group is the business 
group within Lehman Brothers that is primarily responsible for the 
distribution and client service requirements of the Trust and its 
investors. Lehman Brothers Institutional Funds Group has been serving 
institutional clients' investment needs exclusively for more than 20 
years, emphasizing high quality individualized service to clients. 

Investment Adviser

	Lehman Brothers Global Asset Management, Inc. serves as the 
Investment Adviser to each of the Funds.  The Adviser, located at 3 
World Financial Center, New York, New York 10285, is a wholly-owned 
subsidiary of Holdings.  The investment advisory agreements provide 
that the Adviser is responsible for all investment activities of the 
Funds, including executing portfolio strategy, effecting Fund 
purchase and sale transactions and employing professional portfolio 
managers and security analysts who provide research for the Funds.

	Investment personnel of the Adviser may invest in securities for 
their own account pursuant to a code of ethics that establishes 
procedures for personal investing and restricts certain transactions.

	The Investment Advisory Agreement with respect to each of the 
Funds was most recently approved by the Trust's Board of Trustees, 
including a majority of the Trust's "non-interested" Trustees, on 
December 5, 1995 and by shareholders on January 31, 1996.  The 
Investment Advisory Agreements commenced on February 1, 1996 and will 
continue until February 1, 1998 unless terminated or amended prior to 
that date according to its terms.  The Investment Advisory Agreements 
will continue initially for a two-year period and automatically for 
successive annual periods thereafter provided the continuance is 
approved annually (i) by the Trust's Board of Trustees or (ii) by a 
vote of a "majority" (as defined in the 1940 Act) of a Fund's 
outstanding voting securities, except that in either event the 
continuance is also approved by a majority of the Trustees of the 
Trust who are not "interested persons" (as defined in the 1940 Act). 
Each Investment Advisory Agreement may be terminated (i) on 60 days' 
written notice by the Trustees of the Trust, (ii) by vote of holders 
of a majority of a Fund's outstanding voting securities, or upon 90 
days' written notice by Lehman Brothers, or (iii) automatically in 
the event of its assignment (as defined in the 1940 Act).

	Effective February 1, 1996, as compensation for the Adviser's 
services rendered to the Funds, the Adviser is entitled to a fee, 
computed daily and paid monthly, at the annual rate of .20% of the 
average daily net assets of the Fund.  Prior to February 1, 1996, the 
Adviser was entitled to a fee, computed daily and paid monthly, at 
the annual rate of .10% of the average net assets of the Fund.  For 
the fiscal period ended January 31, 1994 and the fiscal years ended 
January 31, 1995 and 1996, the Adviser was entitled to receive 
advisory fees in the following amounts:  the Government Obligations 
Money Market Fund, $72,100, $86,255 and $87,393, respectively, the 
Cash Management Fund, $27,323, $11,931 and $2,930, respectively, and 
the Treasury Instruments Money Market Fund II, $96,737, $357,350 
$408,361, respectively.  Waivers by the Adviser of advisory fees and 
reimbursement of expenses to maintain the Funds' operating expense 
ratios at certain levels amounted to:  the Government Obligations 
Money Market Fund, $72,100 and $163,039, respectively, for the fiscal 
period ended January 31, 1994, $48,079 and $0, respectively, for the 
fiscal year ended January 31, 1995 and $33,786 and $0.00, 
respectively, for the fiscal year ended January 31, 1996; the Cash 
Management Fund, $27,323 and $130,650, respectively, for the fiscal 
year ended January 31, 1994, $11,931 and $45,500, respectively, for 
the fiscal year ended January 31, 1995, and $2,930 and $37,849, 
respectively, for the fiscal year ended January 31, 1996; and the 
Treasury Instruments Money Market Fund II, $96,737 and $173,335, 
respectively for the fiscal period ended January 31, 1994, $231,451 
and $0, respectively, for the fiscal year ended January 31, 1995 and 
$29,150 and $0.00, respectively, for the fiscal year ended January 
31, 1996.  In order to maintain competitive expense ratios during 
1996 and thereafter, the Adviser and Administrator have agreed to 
voluntary fee waivers and expense reimbursements for each of the 
Funds if total operating expenses exceed certain levels.  See 
"Background and Expense Information" in each Fund's Prospectus.

with 99.99% shares held of record.

	As of February 16, 1996, there were no investors in the Class E 
Shares of Treasury Instruments Money Market Fund II and all 
outstanding shares were held by Lehman Brothers.

	As of February 16, 1996, there were no investors in the Class A, 
Class B, or Class C Shares of Cash Management Fund and all

	The investors described above have indicated that they each hold 
their shares on behalf of various accounts and not as beneficial 
owners. To the extent that any investor is the beneficial owner of 
more than 25% of the outstanding shares of a Fund, such investor may 
be deemed to be a "control person" of that Fund for purposes of the 
1940 Act.

Administrator and Transfer Agent

	FDISG, a subsidiary of First Data Corporation, is located at One 
Exchange Place, Boston, Massachusetts 02109, and serves as the 
Trust's Administrator and Transfer Agent.  As the Trust's 
Administrator, FDISG has agreed to provide the following services: 
(i) assist generally in supervising the Funds' operations, providing 
and supervising the operation of an automated data processing system 
to process purchase and redemption orders, providing information 
concerning the Funds to their shareholders of record, handling 
investor problems, supervising the services of employees and

assets of each Fund.  FDISG pays Boston Safe Deposit and Trust 
Company ("Boston Safe"), the Fund's Custodian, a portion of its 
monthly administration fee for custody services rendered to the 
Funds.

	Prior to May 6, 1994, The Boston Company Advisors, Inc. 
("TBCA"), an indirect, wholly-owned subsidiary of Mellon Bank 
Corporation ("Mellon"), served as Administrator of the Funds.  On May 
6, 1994, FDISG acquired TBCA's third party mutual fund administration 
business from Mellon, and each Fund's administration agreement with 
TBCA was assigned to FDISG.  For the fiscal period ended January 31, 
1994 and the fiscal years ended January 31, 1995 and 1996 the 
Administrator was entitled to receive administration fees in the 
following amounts:  the Government Obligations Money Market Fund, 
$72,100, $86,255 and $87,393, respectively, the Cash Management Fund, 
$27,323, $11,931 and $2,930, respectively, and the Treasury 
Instruments Money Market Fund II, $96,737, $357,350 and 408,361, 
respectively.  Waivers by the Administrator of administration fees 
and reimbursement of expenses to maintain the Funds' operating 
expense ratios at certain levels amounted to:  the Government 
Obligations Money Market Fund, $72,100 and $19,087, respectively for 
the fiscal period ended January 31, 1994, $64,842 and $0, 
respectively, for the fiscal year ended January 31, 1995, and $64,487 
and $0.00 for the fiscal year ended January 31, 1996; the Cash 
Management Fund, $27,323 and $9,381, respectively for the fiscal 
period ended January 31, 1994, $9,110 and $0, respectively, for the 
fiscal year ended January 31, 1995, and $2,164 and $0.00 for the 
fiscal year ended January 31, 1996; and the Treasury Instruments 
Money Market Fund II, $96,737 and $42,443, respectively for the 
fiscal period ended January 31, 1994, $269,369 and $0, respectively, 
for the fiscal year ended January 31, 1995 and $301,631 and $0.00 for 
the fiscal year ended January 31, 1996.  In order to maintain 
competitive expense ratios during 1996 and thereafter, the Adviser 
and Administrator have agreed to waive fees or to reimburse the Funds 
if total operating expenses exceed certain levels.  See "Background 
and Expense Information" in each Fund's Prospectus. 

	Under the transfer agency agreement, FDISG maintains the 
investor account records for the Trust, handles certain 
communications between investors and the Trust, distributes dividends 
and distributions payable by the Trust and produces statements with 
respect to account activity for the Trust and its investors. For 
these services, FDISG receives a monthly fee based on average net 
assets and is reimbursed for out-of-pocket expenses.

Custodian

	Boston Safe, a wholly-owned subsidiary of Mellon, is located at 
One Boston Place, Boston, Massachusetts 02108, serves as the 
Custodian of the Trust pursuant to a custody agreement. Under the 
custody agreement, Boston Safe holds each Fund's portfolio securities 
and keeps all necessary accounts and records. For its services, 
Boston Safe receives a monthly fee from FDISG based upon the 
month-end market value of securities held in custody and also 
receives securities transaction charges, including out-of-pocket 
expenses. The assets of the Trust are held under bank custodianship 
in compliance with the 1940 Act. 

Service Organizations

	As stated in the Funds' Prospectuses, a Fund will enter into an 
agreement with each financial institution which may purchase Class B, 
Class C or Class E shares.  The Funds will enter into an agreement 
with each Service Organization whose customers ("Customers") are the 
beneficial owners of Class B, Class C or Class E shares that requires 
the Service Organization to provide certain services to Customers in 
consideration of the Funds' payment of .25%, .35%, or .15%, 
respectively, of the average daily net asset value of the respective 
Class beneficially owned by the Customers.  Such services with 
respect to the Class C shares include: (i) aggregating and processing 
purchase and redemption requests from Customers and placing net 
purchase and redemption orders with a Fund's Distributor; 
(ii) processing dividend payments from the Funds on behalf of 
Customers; (iii) providing information periodically to Customers 
showing their positions in shares; (iv) arranging for bank wires; 
(v) responding to Customer inquiries relating to the services 
performed by the Service Organization and handling correspondence; 
(vi) forwarding investor communications from the Funds (such as 
proxies, investor reports, annual and semi-annual financial 
statements and dividend, distribution and tax notices) to Customers; 
(vii) acting as shareholder of record or nominee; and (viii) other 
similar account administrative services.  In addition, a Service 
Organization at its option, may also provide to its Customers of 
Class C shares (a) a service that invests the assets of their 
accounts in shares pursuant to specific or pre-authorized 
instructions; (b) provide sub-accounting with respect to shares 
beneficially owned by Customers or the information necessary for sub-
accounting; and (c) provide check writing services.  Service 
Organizations that purchase Class C shares will also provide 
assistance in connection with the support of the distribution of 
Class C shares to its Customers, including marketing assistance and 
the forwarding to Customers of sales literature and advertising 
provided by a Distributor of the shares.  Holders of Class B shares 
of a Fund will receive the services set forth in (i) and (v) and may 
receive one or more of the services set forth in (ii), (iii), (iv), 
(vi), (vii) and (viii) above.  A Service Organization, at its option, 
may also provide to its Customers of Class B shares services 
including:  (a) providing Customers with a service that invests the 
assets of their accounts in shares pursuant to specific or pre-
authorized instruction; (b) providing sub-accounting with respect to 
shares beneficially owned by Customers or the information necessary 
for sub-accounting; (c) providing reasonable assistance in connection 
with the distribution of shares to Customers; and (d) providing such 
other similar services as the Fund may reasonably request to the 
extent the Service Organization is permitted to do so under 
applicable statutes, rules, or regulations. Holders of Class E shares 
of a Fund will receive the services set forth in (i) and (v) above.  
A Service Organization, and at its option, may also provide to its 
Customers of Class E shares services including:  those services set 
forth in (ii), (iii), (iv), (vi), (vii) and (viii) above and the 
optional services set forth in (a), (b) and (c) above.

	Each Fund's agreements with Service Organizations are governed 
by a Shareholder Services Plan (the "Plan") that has been adopted by 
the Trust's Board of Trustees under Rule 12b-1 of the 1940 Act.  
Under this Plan, the Board of Trustees reviews, at least quarterly, a 
written report of the amounts expended under the Fund's agreements 
with Service Organizations and the purposes for which the 
expenditures were made. In addition, the Funds' arrangements with 
Service Organizations must be approved annually by a majority of the 
Trust's Trustees, including a majority of the Trustees who are not 
"interested persons" of the Trust as defined in the 1940 Act and have 
no direct or indirect financial interest in such arrangements (the 
"Disinterested Trustees"). 

	The Board of Trustees has approved the Funds' arrangements with 
Service Organizations based on information provided by the Funds' 
service contractors that there is a reasonable likelihood that the 
arrangements will benefit the Funds and their investors by affording 
the Funds greater flexibility in connection with the servicing of the 
accounts of the beneficial owners of their shares in an efficient 
manner. Any material amendment to the Funds' arrangements with 
Service Organizations must be approved by a majority of the Trust's 
Board of Trustees (including a majority of the Disinterested 
Trustees). So long as the Funds' arrangements with Service 
Organizations are in effect, the selection and nomination of the 
members of the Trust's Board of Trustees who are not "interested 
persons" (as defined in the 1940 Act) of the Trust will be committed 
to the discretion of such non-interested Trustees. 

	For the fiscal year ended January 31, 1996, the following 
service fees were paid by Government Obligations Money Market Fund:  
Class B shares, $25,777.60, Class C shares, $3,066.65, and Class E 
shares, $0.00.  For the fiscal year ended January 31, 1995, the 
following service fees were paid by Government Obligations Money 
Market Fund:  Class B shares, $19,702; no service fees were paid with 
respect to Class C or Class E shares.  For the period February 8, 
1993 (commencement of operations) to January 31, 1994, Government 
Obligations Money Market Fund paid $771 in service fees with respect 
to its Class B Shares; no service fees were paid with respect to 
Class C shares.  For the fiscal year ended January 31, 1996, the 
following service fees were paid by Cash Management Fund:  Class B 
shares, $25.62, Class C shares, $0.00, and Class E shares, $0.00.  
For the fiscal year ended January 31, 1995, the following service 
fees were paid by Cash Management Fund:  Class B Shares, $26; Class C 
Shares, $2; no service fees were paid with respect to Class E shares.  
For the period February 8, 1993 (commencement of operations) to 
January 31, 1994, Cash Management Fund did not pay any service fees.  
For the fiscal year ended January 31, 1996, the following service 
fees were paid by Treasury Instruments Money Market Fund II:  Class B 
shares, $80,741.32, Class C shares, $34,595.40, and Class E shares, 
$0.00.  For the fiscal year ended January 31, 1995, the following 
service fees were paid by Treasury Instruments Money Market Fund II:  
Class B Shares, $83,224; no service fees were paid with respect to 
Class C or Class E shares.  For the period February 8, 1993 
(commencement of operations) to January 31, 1994, Treasury 
Instruments Money Market Fund II paid  $35,867 in service fees with 
respect to its Class B Shares; no service fees were paid with respect 
to Class C Shares.  Class E Shares were not offered by the Funds 
during the fiscal period ended January 31, 1994.

Expenses

	The Funds' expenses include taxes, interest, fees and salaries 
of the Trust's Trustees and Officers who are not directors, officers 
or employees of the Trust's service contractors, SEC fees, state 
securities qualification fees, costs of preparing and printing 
prospectuses for regulatory purposes and for distribution to 
investors, advisory, and administration fees, charges of the 
custodian and of the transfer and dividend disbursing agent, Service 
Organization fees, certain insurance premiums, outside auditing and 
legal expenses, costs of investor reports and shareholder meetings 
and any extraordinary expenses.  The Funds also pay for brokerage 
fees and commissions (if any) in connection with the purchase and 
sale of portfolio securities.  The Adviser and FDISG have agreed that 
if, in any fiscal year, the expenses borne by a Fund exceed the 
applicable expense limitations imposed by the securities regulations 
of any state in which shares of the particular Fund are registered or 
qualified for sale to the public, they will reimburse such Fund for 
any excess to the extent required by such regulations in the same 
proportion that each of their fees bears to the Fund's aggregate fees 
for investment advice and administrative services. Unless otherwise 
required by law, such reimbursement would be accrued and paid on the 
same basis that the advisory and administration fees are accrued and 
paid by such Fund.  To the Funds' knowledge, of the expense 
limitations in effect on the date of this Statement of Additional 
Information, none is more restrictive than two and one-half percent 
(2 1/2%) of the first $30 million of a Fund's average net assets, two 
percent (2%) of the next $70 million of the average net assets and 
one and one-half percent (1 1/2%) of the remaining average net 
assets.

ADDITIONAL INFORMATION CONCERNING TAXES

	The following summarizes certain additional tax considerations 
generally affecting each Fund and its investors that are not 
described in each Fund's Prospectus. No attempt is made to present a 
detailed explanation of the tax treatment of the Funds or their 
investors or possible legislative changes, and the discussion here 
and in each Fund's Prospectus is not intended as a substitute for 
careful tax planning. Investors should consult their tax advisers 
with specific reference to their own tax situation. 

	As stated in each Prospectus, each Fund of the Trust is treated 
as a separate corporate entity under the Code and qualified as a 
regulated investment company under the Code and intends to so qualify 
in future years. In order to so qualify for a taxable year, each Fund 
must satisfy the distribution requirement described in its 
Prospectus, derive at least 90% of its gross income for the year from 
certain qualifying sources, comply with certain diversification tests 
and derive less than 30% of its gross income from the sale or other 
disposition of securities and certain other investments held for less 
than three months. Interest (including original issue discount and 
accrued market discount) received by a Fund upon maturity or 
disposition of a security held for less than three months will not be 
treated as gross income derived from the sale or other disposition of 
such security within the meaning of this requirement. However, any 
other income which is attributable to realized market appreciation 
will be treated as gross income from the sale or other disposition of 
securities for this purpose. 

	A 4% nondeductible excise tax is imposed on regulated investment 
companies that fail to distribute currently an amount equal to 
specified percentages of their ordinary taxable income and capital 
gain net income (excess of capital gains over capital losses). Each 
Fund intends to make sufficient distributions or deemed distributions 
of its ordinary taxable income and any capital gain net income each 
calendar year to avoid liability for this excise tax. 

	If for any taxable year a Fund does not qualify for tax 
treatment as a regulated investment company, all of its taxable 
income will be subject to federal income tax at regular corporate 
rates without any deduction for distributions to Fund investors. In 
such event, dividend distributions would be taxable as ordinary 
income to the Fund's investors to the extent of its current and 
accumulated earnings and profits, and would be eligible for the 
dividends received deduction in the case of corporate shareholders. 

	Each Fund will be required in certain cases to withhold and 
remit to the U.S. Treasury 31% of taxable dividends or 31% of gross 
proceeds realized upon sale paid to any investor who has failed to 
provide a correct tax identification number in the manner required, 
or who is subject to withholding by the Internal Revenue Service for 
failure to properly include on his return payments of taxable 
interest or dividends, or who has failed to certify to the Fund that 
he is not subject to backup withholding when required to do so or 
that he is an "exempt recipient." 

	Depending upon the extent of the Funds' activities in states and 
localities in which their offices are maintained, in which their 
agents or independent contractors are located or in which they are 
otherwise deemed to be conducting business, the Funds may be subject 
to the tax laws of such states or localities. In addition, in those 
states and localities which have income tax laws, the treatment of 
the Funds and their investors under such laws may differ from their 
treatment under federal income tax laws. Investors are advised to 
consult their tax advisers concerning the application of state and 
local taxes. 

	The foregoing discussion is based on federal tax laws and 
regulations which are in effect on the date of this Statement of 
Additional Information; such laws and regulations may be changed by 
legislative or administrative action. 

DIVIDENDS

	Net income of each of the Funds for dividend purposes consists 
of (i) interest accrued and original issue discount earned on the 
Fund's assets, (ii) plus the amortization of market discount and 
minus the amortization of market premium on such assets, (iii) less 
accrued expenses directly attributable to the Fund and the general 
expenses (e.g., legal, accounting and trustees' fees) of the Trust 
prorated to the Fund on the basis of its relative net assets. In 
addition, Class B, Class C and Class E shares bear exclusively the 
expense of fees paid to Service Organizations with respect to the 
relevant Class of shares. See "Management of the Funds-Service 
Organizations." With respect to the Cash Management Fund dividends 
may be based on estimates of net interest income for the Fund.  
Actual income may differ from estimates and differences, if any, will 
be included in the calculation of subsequent dividends.

	As stated, the Trust uses its best efforts to maintain the net 
asset value per share of each Fund at $1.00. As a result of a 
significant expense or realized or unrealized loss incurred by either 
of these portfolios, it is possible that the portfolio's net asset 
value per share may fall below $1.00. 

ADDITIONAL YIELD INFORMATION

	The "yields" and "effective yields" are calculated separately 
for each class of shares of each Fund and in accordance with the 
formulas prescribed by the SEC. The seven-day yield for each class of 
shares is calculated by determining the net change in the value of a 
hypothetical pre-existing account in the particular Fund which has a 
balance of one share of the class involved at the beginning of the 
period, dividing the net change by the value of the account at the 
beginning of the period to obtain the base period return, and 
multiplying the base period return by 365/7. The net change in the 
value of an account in a Fund includes the value of additional shares 
purchased with dividends from the original share and dividends 
declared on the original share and any such additional shares, net of 
all fees charged to all investor accounts in proportion to the length 
of the base period and the Fund's average account size, but does not 
include gains and losses or unrealized appreciation and depreciation. 
In addition, an effective annualized yield quotation may be computed 
on a compounded basis with respect to each class of its shares by 
adding 1 to the base period return for the class involved (calculated 
as described above), raising that sum to a power equal to 365/7, and 
subtracting 1 from the result. 

	Similarly, based on the calculations described above, the Funds' 
30-day (or one-month) yields and effective yields may also be 
calculated. Such yields refer to the average daily income generated 
over a 30-day (or one-month) period, as appropriate. 

	Based on the period ended January 31, 1996, the yields and 
effective yields for each of the Funds were as follows:

**estimated yield without fee waivers and/or expense reimbursements

	Class B, Class C and Class E Shares bear the expenses of fees 
paid to Service Organizations. As a result, at any given time, the 
net yield of Class B, Class C and Class E Shares could be up to .25%, 
 .35%, and .15% lower than the net yield of Class A Shares, 
respectively.  

	From time to time, in advertisements or in reports to investors, 
the performance of the Funds may be quoted and compared to that of 
other money market funds or accounts with similar investment 
objectives and to stock or other relevant indices. For example, the 
yields of the Funds may be compared to the Donoghue's Money Fund 
Average, which is an average compiled by IBC/Donoghue's MONEY FUND 
REPORT of Holliston, MA 01746, a widely recognized independent 
publication that monitors the performance of money market funds, or 
to the average yields reported by the Bank Rate Monitor from money 
market deposit accounts offered by the 50 leading banks and thrift 
institutions in the top five standard metropolitan statistical areas. 

	The Funds' yields will fluctuate and any quotation of yield 
should not be considered as representative of the future performance 
of the Funds. Since yields fluctuate, yield data cannot necessarily 
be used to compare an investment in the Funds' shares with bank 
deposits, savings accounts and similar investment alternatives which 
often provide an agreed or guaranteed fixed yield for a stated period 
of time. Investors should remember that performance and yield are 
generally functions of the kind and quality of the investments held 
in a portfolio, portfolio maturity, operating expenses net of waivers 
and expense reimbursements and market conditions. Any fees charged by 
Service Organizations or other institutional investors with respect 
to customer accounts in investing in shares of the Funds will not be 
included in calculations of yield; such fees, if charged, would 
reduce the actual yield from that quoted. 

ADDITIONAL DESCRIPTION CONCERNING FUND SHARES

	The Trust does not presently intend to hold annual meetings of 
shareholders except as required by the 1940 Act or other applicable 
law. The law under certain circumstances provides shareholders with 
the right to call for a meeting of shareholders to consider the 
removal of one or more Trustees. To the extent required by law, the 
Trust will assist in shareholder communication in such matters. 

	As stated in the Prospectuses for the Funds, holders of each 
Fund's shares, will vote in the aggregate and not by class on all 
matters, except where otherwise required by law and except that for 
each Fund only that Fund's Class B, Class C and Class E shares will 
be entitled to vote on matters submitted to a vote of shareholders 
pertaining to the Fund's arrangements with Service Organizations with 
respect to the relevant Class of shares. (See "Management of the 
Funds-Service Organizations"). Further, shareholders of all of the 
Trust's portfolios will vote in the aggregate and not by portfolio 
except as otherwise required by law or when the Board of Trustees 
determines that the matter to be voted upon affects only the 
interests of the shareholders of a particular portfolio. Rule 18f-2 
under the 1940 Act provides that any matter required to be submitted 
by the provisions of such Act or applicable state law, or otherwise, 
to the holders of the outstanding securities of an investment company 
such as the Trust shall not be deemed to have been effectively acted 
upon unless approved by the holders of a majority of the outstanding 
shares of each portfolio affected by the matter. Rule 18f-2 further 
provides that a portfolio shall be deemed to be affected by a matter 
unless it is clear that the interests of each portfolio in the matter 
are identical or that the matter does not affect any interest of the 
portfolio. Under the Rule the approval of an investment advisory 
agreement or any change in a fundamental investment policy would be 
effectively acted upon with respect to a portfolio only if approved 
by the holders of a majority of the outstanding voting securities of 
such portfolio. However, the Rule also provides that the ratification 
of the selection of independent auditors, the approval of principal 
underwriting contracts and the election of Trustees are not subject 
to the separate voting requirements and may be effectively acted upon 
by shareholders of the investment company voting without regard to 
portfolio. 

	On August 22, 1994, the Cash Management Fund changed its name 
from the 100% Government Money Market Fund to the Cash Management 
Fund.





COUNSEL

	Willkie Farr & Gallagher, One Citicorp Center, 153 East 53rd

Farr & Gallagher also serves as counsel to Lehman Brothers.

INDEPENDENT AUDITORS

	Ernst & Young LLP, independent auditors, serve as independent 
auditors to the Fund and render an opinion on each Fund's financial 
statements. Ernst & Young has offices at 200 Clarendon Street,

FINANCIAL STATEMENTS

	The Trust's Annual Report for the fiscal period ended January 
31, 1995 and its Semi-Annual Report for the six-months ended July 31, 
1995 are incorporated into this Statement of Additional Information 
by reference in their entirety.

MISCELLANEOUS

Shareholder Vote

	As used in this Statement of Additional Information and the 
Prospectuses for the Funds, a "majority of the outstanding shares" of 
a Fund or of any other portfolio means the lesser of (1) 67% of the 
shares of such Fund (irrespective of class) or of the portfolio 
represented at a meeting at which the holders of more than 50% of the 
outstanding shares of such Fund or portfolio are present in person or 
by proxy or (2) more than 50% of the outstanding shares of such Fund 
(irrespective of class) or of the portfolio. 

Shareholder and Trustee Liability

	The Trust is organized as a "business trust" under the laws of 
the Commonwealth of Massachusetts. Shareholders of such a trust may, 
under certain circumstances, be held personally liable (as if they 
were partners) for the obligations of the trust. The Declaration of 
Trust of the Trust provides that shareholders of the Funds shall not 
be subject to any personal liability for the acts or obligations of 
the Trust and that every note, bond, contract, order or other 
undertaking made by the Trust shall contain a provision to the effect 
that the shareholders are not personally liable thereunder. The 
Declaration of Trust provides for indemnification out of the trust 
property of a Fund of any shareholder of the Fund held personally 
liable solely by reason of his being or having been a shareholder and 
not because of his acts or omissions or some other reason. The 
Declaration of Trust also provides that the Trust shall, upon 
request, assume the defense of any claim made against any shareholder 
for any act or obligation of the Trust and satisfy any judgment 
thereon. Thus, the risk of a shareholder incurring financial loss 
beyond its investment in a Fund on account of shareholder liability 
is limited to circumstances in which the Fund itself would be unable 
to meet its obligations. 

	The Trust's Declaration of Trust provides further that no 
Trustee, Officer or agent of the Trust shall be personally liable for 
or on account of any contract, debt, tort, claim, damage, judgment or 
decree arising out of or connected with the administration or 
preservation of the trust estate or the conduct of any business of 
the Trust, nor shall any Trustee be personally liable to any person 
for any action or failure to act except by reason of his own bad 
faith, willful misfeasance, gross negligence in the performance of 
his duties or by reason of reckless disregard of his obligations and 
duties as Trustee. It also provides that all persons having any claim 
against the Trustees or the Trust shall look solely to the trust 
property for payment. With the exceptions stated, the Declaration of 
Trust provides that a Trustee is entitled to be indemnified against 
all liabilities and expenses reasonably incurred by him in connection 
with the defense or disposition of any proceeding in which he may be 
involved or with which he may be threatened by reason of his being or 
having been a Trustee, and that the Trustees have the power, but not 
the duty, to indemnify officers and employees of the Trust unless 
such person would not be entitled to indemnification had he been a 
Trustee.

THE TRUST

	Lehman Brothers Institutional Funds Group Trust (the "Trust") is 
an open-end management investment company. The Trust currently 
includes a family of portfolios, two of which are Municipal Money 
Market Fund and Tax-Free Money Market Fund (individually, a "Fund", 
collectively, the "Funds"). 

	Although the Funds have the same Investment Adviser, Lehman 
Brothers Global Asset Management, Inc. (the "Adviser"), and have 
comparable investment objectives, their yields will normally vary due 
to their differing cash flows and their differing types of portfolio 
securities (for example, the Tax-Free Money Market Fund invests only 
in First Tier Eligible Securities whereas the Municipal Money Market 
Fund may invest in Eligible Securities that are not First Tier).

	THIS STATEMENT OF ADDITIONAL INFORMATION AND FUNDS' PROSPECTUSES 
RELATE PRIMARILY TO THE FUNDS AND DESCRIBE ONLY THE INVESTMENT 
OBJECTIVES AND POLICIES, OPERATIONS, CONTRACTS AND OTHER MATTERS 
RELATING TO THE FUNDS. INVESTORS WISHING TO OBTAIN SIMILAR 
INFORMATION REGARDING THE TRUST'S OTHER PORTFOLIOS MAY OBTAIN 
INFORMATION DESCRIBING THEM BY CONTACTING LEHMAN BROTHERS AT 1-
800-368-5556.

INVESTMENT OBJECTIVE AND POLICIES 

	As stated in the Funds' Prospectuses, the investment objective 
of each Fund is to provide as high a level of current income exempt 
from federal income tax as is consistent with relative stability of 
principal. The following policies supplement the description of each 
Fund's investment objective and policies as contained in the 
applicable Prospectus. 

	The Funds are managed to provide stability of capital while 
achieving competitive yields. The Adviser intends to follow a 
value-oriented, research-driven and risk-averse investment strategy, 
engaging in a full range of economic, strategic, credit and 
market-specific analyses in researching potential investment 
opportunities. 

Portfolio Transactions

	Subject to the general control of the Trust's Board of Trustees, 
the Adviser is responsible for, makes decisions with respect to and 
places orders for all purchases and sales of portfolio securities for 
the Funds. Purchases of portfolio securities are usually principal 
transactions without brokerage commissions. In making portfolio 
investments, the Adviser seeks to obtain the best net price and the 
most favorable execution of orders. To the extent that the execution 
and price offered by more than one dealer are comparable, the Adviser 
may, in its discretion, effect transactions in portfolio securities 
with dealers who provide the Trust with research advice or other 
services. 

	Transactions in the over-the-counter market are generally 
principal transactions with dealers, and the costs of such 
transactions involve dealer spreads rather than brokerage 
commissions. With respect to over-the-counter transactions, the 
Funds, where possible, will deal directly with the dealers who make a 
market in the securities involved except in those circumstances where 
better prices and execution are available elsewhere. 

	Investment decisions for each Fund are made independently from 
those for the Trust's other portfolios or other investment company 
portfolios or accounts managed by the Adviser.  Such other portfolios 
may invest in the same securities as the Funds. When purchases or 
sales of the same security are made at substantially the same time on 
behalf of such other portfolios, transactions are averaged as to 
price, and available investments allocated as to amount, in a manner 
which the Adviser believes to be equitable to each portfolio, 
including the Funds. In some instances, this investment procedure may 
adversely affect the price paid or received by the Funds or the size 
of the position obtained for the Funds. To the extent permitted by 
law, the Adviser may aggregate the securities to be sold or purchased 
for the Funds with those to be sold or purchased for such other 
portfolios in order to obtain best execution. 

	The Funds will not execute portfolio transactions through, 
acquire portfolio securities issued by, make savings deposits in, or 
enter into repurchase agreements with Lehman Brothers or the Adviser 
or any affiliated person (as such term is defined in the Investment 
Company Act of 1940, as amended (the "1940 Act")) of any of them, 
except to the extent permitted by the Securities and Exchange 
Commission (the "SEC"). In addition, the Funds will not purchase 
"Municipal Obligations" during the existence of any underwriting or 
selling group relating thereto of which Lehman Brothers or any 
affiliate thereof is a member, except to the extent permitted by the 
SEC. "Municipal Obligations" consist of municipal obligations (as 
defined in each Fund's Prospectus) and tax-exempt derivatives such as 
tender option bonds, participation's, beneficial interests in trusts 
and partnership interests. Under certain circumstances, the Funds may 
be at a disadvantage because of these limitations in comparison with 
other investment company portfolios which have a similar investment 
objective but are not subject to such limitations. Furthermore, with 
respect to such transactions, securities, deposits and agreements a 
Fund will not give preference to Service Organizations with which a 
Fund enters into agreements.  (See the Prospectuses, "Management of 
the Fund-Service Organizations").

	The Funds may participate, if and when practicable, in bidding 
for the purchase of Municipal Obligations directly from an issuer in 
order to take advantage of the lower purchase price available to 
members of a bidding group. A Fund will engage in this practice, 
however, only when the Adviser, in its sole discretion, believes such 
practice to be in a Fund's interest. 

	The Funds may seek profits through short-term trading. Each 
Fund's annual portfolio turnover will be relatively high, but 
brokerage commissions are normally not paid on money market 
instruments and the Funds' portfolio turnover is not expected to have 
a material effect on the net incomes of the Funds. Each Fund's 
portfolio turnover rate is expected to be zero for regulatory 
reporting purposes.

Additional Information on Investment Practices

	Variable and Floating Rate Instruments.  Municipal Obligations 
purchased by the Funds may include variable and floating rate 
instruments, which provide for adjustments in the interest rate on 
certain reset dates or whenever a specified interest rate index 
changes, respectively. Variable and floating rate instruments are 
subject to the credit quality standards described in the 
Prospectuses. In some cases the Funds  may require that the 
obligation to pay the principal of the instrument be backed by a 
letter or line of credit or guarantee. Such instruments may carry 
stated maturities in excess of 397 days provided that the 
maturity-shortening provisions stated in Rule 2a-7 under the 1940 Act 
are satisfied. Although a particular variable or floating rate demand 
instrument may not be actively traded in a secondary market, in some 
cases, the Funds may be entitled to principal on demand and may be 
able to resell such notes in the dealer market. 

	Variable and floating rate demand instruments held by a Fund may 
have maturities of more than thirteen months provided: (i) the Fund 
is entitled to the payment of principal at any time, or during 
specified intervals not exceeding 13 months, upon giving the 
prescribed notice (which may not exceed 30 days), and (ii) the rate 
of interest on such instruments is adjusted at periodic intervals 
which may extend up to 13 months (397 days). Variable and floating 
rate notes that do not provide for payment within seven days may be 
deemed illiquid and subject to the 10% limitation on such 
investments. 

	In determining a Fund's average weighted portfolio maturity and 
whether a variable or floating rate demand instrument has a remaining 
maturity of thirteen months or less, each instrument will be deemed 
by a Fund to have a maturity equal to the longer of the period 
remaining until its next interest rate adjustment or the period 
remaining until the principal amount can be recovered through demand. 
In determining whether an unrated variable or floating rate demand 
instrument is of comparable quality at the time of purchase to 
securities in which a Fund may invest, the Adviser will follow 
guidelines adopted by the Trust's Board of Trustees. 

	Tender Option Bonds.  Each Fund may invest up to 10% of the 
value of its assets in tender option bonds. A Fund will not purchase 
tender option bonds unless (a) the demand feature applicable thereto 
is exercisable by the Fund within 13 months of the date of such 
purchase upon no more than 30 days' notice and thereafter is 
exercisable by the Fund no less frequently than annually upon no more 
than 30 days' notice and (b) at the time of such purchase, the 
Adviser reasonably expects that, (i) based upon its assessment of 
current and historical interest rate trends, prevailing short-term 
tax-exempt rates will not exceed the stated interest rate on the 
underlying Municipal Obligations at the time of the next tender fee 
adjustment and (ii) the circumstances which might entitle the grantor 
of a tender option to terminate the tender option would not occur 
prior to the time of the next tender opportunity. At the time of each 
tender opportunity, a Fund will exercise the tender option with 
respect to any tender option bonds unless the Adviser reasonably 
expects that, (a) based upon its assessment of current and historical 
interest rate trends, prevailing short-term tax-exempt rates will not 
exceed the stated interest rate on the underlying Municipal 
Obligations at the time of the next tender fee adjustment and (b) the 
circumstances which might entitle the grantor of a tender option to 
terminate the tender option would not occur prior to the time of the 
next tender opportunity. The Funds will exercise the tender feature 
with respect to tender option bonds, or otherwise dispose of their 
tender option bonds, prior to the time the tender option is scheduled 
to expire pursuant to the terms of the agreement under which the 
tender option is granted. The Funds otherwise will comply with the 
provisions of Rule 2a-7 under the 1940 Act in connection with the 
purchase of tender option bonds, including, without limitation, the 
requisite determination by the Board of Trustees that the tender 
option bonds in question meet the quality standards described in 
Rule 2a-7. In the event of a default of the Municipal Obligation 
underlying a tender option bond, or the termination of the tender 
option agreement, a Fund would look to the maturity date of the 
underlying security for purposes of compliance with Rule 2a-7 and, if 
its remaining maturity was greater than 13 months, the Fund would 
sell the security as soon as would be practicable. Each Fund will 
purchase tender option bonds only when it is satisfied that (a) the 
custodial and tender option arrangements, including the fee payment 
arrangements, will not adversely affect the tax-exempt status of the 
underlying Municipal Obligations and (b) payment of any tender fees 
will not have the effect of creating taxable income for the Fund. 
Based on the tender option bond arrangement, each Fund expects to 
value the tender option bond at par; however, the value of the 
instrument will be monitored to assure that it is valued at fair 
value. 

	When-Issued Securities.  As stated in the Funds' Prospectuses, 
the Funds may purchase Municipal Obligations on a "when-issued" basis 
(i.e., for delivery beyond the normal settlement date at a stated 
price and yield). When a Fund agrees to purchase when-issued 
securities, the Custodian will set aside cash or liquid portfolio 
securities equal to the amount of the commitment in a separate 
account. Normally, the Custodian will set aside portfolio securities 
to satisfy a purchase commitment, and in such a case that Fund may be 
required subsequently to place additional assets in the separate 
account in order to ensure that the value of the account remains 
equal to the amount of such Fund's commitment. It may be expected 
that a Fund's net assets will fluctuate to a greater degree when it 
sets aside portfolio securities to cover such purchase commitments 
than when it sets aside cash. Because that Fund will set aside cash 
or liquid assets to satisfy its purchase commitments in the manner 
described, such Fund's liquidity and ability to manage its portfolio 
might be affected in the event its commitments to purchase 
when-issued securities ever exceeded 25% of the value of its assets. 
When a Fund engages in when-issued transactions, it relies on the 
seller to consummate the trade. Failure of the seller to do so may 
result in such Fund's incurring a loss or missing an opportunity to 
obtain a price considered to be advantageous. The Funds do not intend 
to purchase when-issued securities for speculative purposes but only 
in furtherance of their investment objective. Each Fund reserves the 
right to sell the securities before the settlement date if it is 
deemed advisable. 

	Stand-By Commitments.  Each Fund may acquire "stand-by 
commitments" with respect to Municipal Obligations held in its 
portfolio. Under a stand-by commitment, a dealer would agree to 
purchase at a Fund's option specified Municipal Obligations at their 
amortized cost value to the Fund plus accrued interest, if any.  
(Stand-by commitments acquired by a Fund may also be referred to as 
"put" options.) Stand-by commitments may be exercisable by a Fund at 
any time before the maturity of the underlying Municipal Obligations 
and may be sold, transferred or assigned only with the instruments 
involved. A Fund's right to exercise stand-by commitments will be 
unconditional and unqualified. 

	The amount payable to a Fund upon its exercise of a stand-by 
commitment will normally be (i) the Fund's acquisition cost of the 
Municipal Obligations (excluding any accrued interest which the Fund 
paid on their acquisition), less any amortized market premium or plus 
any amortized market or original issue discount during the period the 
Fund owned the securities, plus (ii) all interest accrued on the 
securities since the last interest payment date during that period. 

	Each Fund expects that stand-by commitments will generally be 
available without the payment of any direct or indirect 
consideration. However, if necessary or advisable, a Fund may pay for 
a stand-by commitment either separately in cash or by paying a higher 
price for portfolio securities which are acquired subject to the 
commitment (thus reducing the yield to maturity otherwise available 
for the same securities). The total amount paid in either manner for 
outstanding stand-by commitments held by a Fund will not exceed 1/2 
of 1% of the value of that Fund's total assets calculated immediately 
after each stand-by commitment is acquired. 

	Each Fund intends to enter into stand-by commitments only with 
dealers, banks and broker-dealers which, in the opinion of the 
Adviser, present minimal credit risks. A Fund's reliance upon the 
credit of these dealers, banks and broker-dealers will be secured by 
the value of the underlying Municipal Obligations that are subject to 
the commitment. 

	Each Fund would acquire stand-by commitments solely to 
facilitate portfolio liquidity and does not intend to exercise its 
rights thereunder for trading purposes. The acquisition of a stand-by 
commitment would not affect the valuation or assumed maturity of the 
underlying Municipal Obligations, which would continue to be valued 
in accordance with the amortized cost method. Stand-by commitments 
acquired by a Fund would be valued at zero in determining net asset 
value. Where a Fund paid any consideration directly or indirectly for 
a stand-by commitment, its cost would be reflected as unrealized 
depreciation for the period during which the commitment was held by 
that Fund. 

	Participations.  Each Fund may purchase from financial 
institutions tax-exempt participation interests in Municipal 
Obligations. A participation interest gives a Fund an undivided 
interest in the Municipal Obligation in the proportion that the 
Fund's participation interest bears to the total amount of the 
Municipal Obligation. These instruments may have floating or variable 
rates of interest. If the participation interest is unrated, it will 
be backed by an irrevocable letter of credit or guarantee of a bank 
that the Trust's Board of Trustees has determined meets certain 
quality standards or the payment obligation otherwise will be 
collateralized by obligations of the U.S. government and its agencies 
and instrumentalities ("U.S. Government securities") Each Fund will 
have the right, with respect to certain participation interests, to 
demand payment, on a specified number of days' notice, for all or any 
part of the Fund's interest in the Municipal Obligations, plus 
accrued interest. Each Fund will invest no more than 5% of its total 
assets in participation interests. 

	Illiquid Securities.  A Fund may not invest more than 10% of its 
total net assets in illiquid securities, including securities that 
are illiquid by virtue of the absence of a readily available market 
or legal or contractual restrictions on resale. Securities that have 
legal or contractual restrictions on resale but have a readily 
available market are not considered illiquid for purposes of this 
limitation. 

	The SEC has adopted Rule 144A under the Securities Act of 1933, 
as amended (the "1933 Act") which allows for a broader institutional 
trading market for securities otherwise subject to restriction on 
resale to the general public. Rule 144A establishes a "safe harbor" 
from the registration requirements of the 1933 Act for resales of 
certain securities to qualified institutional buyers. The Adviser 
anticipates that the market for certain restricted securities such as 
institutional municipal securities will expand further as a result of 
this regulation and the development of automated systems for the 
trading, clearance and settlement of unregistered securities of 
domestic and foreign issuers, such as the PORTAL system sponsored by 
the National Association of Securities Dealers. 

	The Adviser will monitor on an ongoing basis the liquidity of 
restricted securities under the supervision of the Board of Trustees. 
In reaching liquidity decisions with respect to Rule 144A securities, 
the Adviser will consider, inter alia, the following factors: (1) the 
unregistered nature of a Rule 144A security; (2) the frequency of 
trades and quotes for a Rule 144A security; (3) the number of dealers 
willing to purchase or sell the Rule 144A security and the number of 
other potential purchasers; (4) dealer undertakings to make a market 
in the Rule 144A security; (5) the trading markets for the Rule 144A 
security; and (6) the nature of the Rule 144A security and the nature 
of marketplace trades (including the time needed to dispose of the 
Rule 144A security, methods of soliciting offers and mechanics of 
transfer). 

	The Appendix to this Statement of Additional Information 
contains a description of the relevant rating symbols used by 
nationally recognized statistical rating organizations ("NRSROs") for 
Municipal Obligations that may be purchased by the Funds. 

Investment Limitations

	The Funds' Prospectuses summarize certain investment limitations 
that may not be changed without the affirmative vote of the holders 
of a majority of a Fund's outstanding shares (as defined below under 
"Miscellaneous"). Investment limitations numbered 1 through 7 may not 
be changed without such a vote of shareholders; investment 
limitations 8 through 13 may be changed by a vote of the Trust's 
Board of Trustees at any time. 



	A Fund may not: 

	 1.	Purchase the securities of any issuer if as a result more 
than 5% of the value of the Fund's assets would be invested in the 
securities of such issuer except that up to 25% of the value of the 
Fund's assets may be invested without regard to this 5% limitation 
and provided that there is no limitation with respect to investments 
in U.S. Government securities. 

 2.	Borrow money, except that the Fund may (i) borrow money for 
temporary or emergency purposes (not for leveraging or investment) 
from banks or, subject to specific authorization by the SEC, from 
funds advised by the Adviser or an affiliate of the Adviser, and (ii) 
engage in reverse repurchase agreements, provided that (i) and (ii) 
in combination do not exceed one-third of the value of the particular 
Fund's total assets (including the amount borrowed) less liabilities 
(other than borrowings).  A Fund may not mortgage, pledge or 
hypothecate its assets except in connection with such borrowings and 
reverse repurchase agreements and then only in amounts not exceeding 
one-third of the value of the particular Fund's total assets.  
Additional investments will not be made when borrowings exceed 5% of 
the Fund's assets. 

 3.	Make loans, except that a Fund may (i) purchase or hold debt 
obligations in accordance with its investment objective and policies, 
(ii) enter into repurchase agreements for securities, (iii) lend 
portfolio securities and (iv) subject to specific authorization by 
the SEC, lend money to other funds advised by the Adviser or an 
affiliate of the Adviser. 

	 4.	Act as an underwriter of securities, except insofar as the 
Fund may be deemed an underwriter under applicable securities laws in 
selling portfolio securities. 

	 5.	Purchase or sell real estate or real estate limited 
partnerships, provided that the Fund may purchase securities of 
issuers which invest in real estate or interests therein. 

	 6.	Purchase or sell commodities or commodity contracts, or 
invest in oil, gas or mineral exploration or development programs or 
in mineral leases. 

	 7.	Purchase any securities which would cause 25% or more of 
the value of its total assets at the time of purchase to be invested 
in the securities of issuers conducting their principal business 
activities in the same industry, provided that there is no limitation 
with respect to investments in U.S. Government securities. 

	 8.	Knowingly invest more than 10% of the value of the Fund's 
assets in securities that may be illiquid because of legal or 
contractual restrictions on resale or securities for which there are 
no readily available market quotations. 

	 9.	Purchase securities on margin, make short sales of 
securities or maintain a short position. 

	10.	Write or sell puts, calls, straddles, spreads or 
combinations thereof. 

	11.	Invest in securities if as a result the Fund would then 
have more than 15% (or such lesser amount as set by state securities 
laws) of its total assets in securities of companies (including 
predecessors) with less than three years of continuous operation. 

	12.	Purchase securities of other investment companies except 
as permitted under the 1940 Act or in connection with a merger, 
consolidation, acquisition or reorganization. 

	13.	Invest in warrants. 

	In addition, without the affirmative vote of the holders of a 
majority of a Fund's outstanding shares, such Fund may not change its 
policy of investing at least 80% of its total assets (except during 
temporary defensive periods) in Municipal Obligations in the case of 
Municipal Money Market Fund, and in obligations the interest on which 
is exempt from federal income tax in the case of the Tax-Free Money 
Market Fund. 

	In order to permit the sale of Fund shares in certain states, 
the Funds may make commitments more restrictive than the investment 
policies and limitations above. Should a Fund determine that any such 
commitments are no longer in its best interests, it will revoke the 
commitment by terminating sales of its shares in the state involved.

MUNICIPAL OBLIGATIONS

In General

	Municipal Obligations include debt obligations issued by 
governmental entities to obtain funds for various public purposes, 
including the construction of a wide range of public facilities, the 
refunding of outstanding obligations, the payment of general 
operating expenses and the extension of loans to public institutions 
and facilities. Private activity bonds that are or were issued by or 
on behalf of public authorities to finance various privately operated 
facilities are included within the term Municipal Obligations if the 
interest paid thereon is exempt from federal income tax. Opinions 
relating to the validity of Municipal Obligations and to the 
exemption of interest thereon from federal income taxes are rendered 
by counsel to the issuers or bond counsel to the respective issuing 
authorities at the time of issuance. Neither the Funds nor the 
Adviser will review independently the underlying proceedings relating 
to the issuance of Municipal Obligations or the bases for such 
opinions. 

	The Funds may hold tax-exempt derivatives which may be in the 
form of tender option bonds, participations, beneficial interests in 
a trust, partnership interests or other forms. A number of different 
structures have been used. For example, interests in long-term fixed 
rate Municipal Obligations held by a bank as trustee or custodian are 
coupled with tender option, demand and other features when tax-exempt 
derivatives are created. Together, these features entitle the holder 
of the interest to tender (or put) the underlying Municipal 
Obligation to a third party at periodic intervals and to receive the 
principal amount thereof. In some cases, Municipal Obligations are 
represented by custodial receipts evidencing rights to receive 
specific future interest payments, principal payments or both, on the 
underlying municipal securities held by the custodian. Under such 
arrangements, the holder of the custodial receipt has the option to 
tender the underlying municipal securities at its face value to the 
sponsor (usually a bank or broker-dealer or other financial 
institution), which is paid periodic fees equal to the difference 
between the bond's fixed coupon rate and the rate that would cause 
the bond, coupled with the tender option, to trade at par on the date 
of a rate adjustment. The Funds may hold tax-exempt derivatives, such 
as participation interests and custodial receipts, for Municipal 
Obligations which give the holder the right to receive payment of 
principal subject to the conditions described above. The Internal 
Revenue Service has not ruled on whether the interest received on 
tax-exempt derivatives in the form of participation interests or 
custodial receipts is tax-exempt, and accordingly, purchases of any 
such interests or receipts are based on the opinion of counsel to the 
sponsors of such derivative securities. Neither the Funds nor the 
Adviser will review independently the underlying proceedings related 
to the creation of any tax-exempt derivatives or the bases for such 
opinions. 

	As described in the Funds' Prospectuses, the two principal 
classifications of Municipal Obligations consist of "general 
obligation" and "revenue" issues, and each Fund's portfolio may 
include "moral obligation" issues, which are normally issued by 
special purpose authorities. There are, of course, variations in the 
quality of Municipal Obligations both within a particular 
classification and between classifications, and the yields on 
Municipal Obligations depend upon a variety of factors, including 
general money market conditions, the financial condition of the 
issuer, general conditions of the municipal bond market, the size of 
a particular offering, the maturity of the obligation and the rating 
of the issue. The ratings of NRSROs represent their opinions as to 
the quality of Municipal Obligations. It should be recognized, 
however, that ratings are general and are not absolute standards of 
quality, and Municipal Obligations with the same maturity, interest 
rate and rating may have different yields while Municipal Obligations 
of the same maturity and interest rate with different ratings may 
have the same yield. Subsequent to its purchase by a Fund, an issue 
of Municipal Obligations may cease to be rated or its rating may be 
reduced below the minimum rating required for purchase by the Fund. 
The Adviser will consider such an event in determining whether a Fund 
should continue to hold the obligation. 

	An issuer's obligations under its Municipal Obligations are 
subject to the provisions of bankruptcy, insolvency and other laws 
affecting the rights and remedies of creditors, such as the federal 
Bankruptcy Code, and laws, if any, which may be enacted by federal or 
state legislatures extending the time for payment of principal or 
interest or both, or imposing other constraints upon enforcement of 
such obligations or upon the ability of municipalities to levy taxes. 
The power or ability of an issuer to meet its obligations for the 
payment of interest on and principal of its Municipal Obligations may 
be materially adversely affected by litigation or other conditions. 

	Among other instruments, each Fund may purchase short-term 
General Obligation Notes, Tax Anticipation Notes, Bond Anticipation 
Notes, Revenue Anticipation Notes, Tax-Exempt Commercial Paper, 
Construction Loan Notes and other forms of short-term loans. Such 
notes are issued with a short-term maturity in anticipation of the 
receipt of tax funds, the proceeds of bond placements or other 
revenues. In addition, each Fund may invest in other types of 
tax-exempt instruments such as municipal bonds, private activity 
bonds and pollution control bonds, provided they have remaining 
maturities of 13 months or less at the time of purchase. 

	The payment of principal and interest on most securities 
purchased by a Fund will depend upon the ability of the issuers to 
meet their obligations. The District of Columbia, each state, each of 
their political subdivisions, agencies, instrumentalities, and 
authorities and each multi-state agency of which a state is a member 
is a separate "issuer" as that term is used in this Statement of 
Additional Information and the Funds' Prospectuses. The 
non-governmental user of facilities financed by private activity 
bonds is also considered to be an "issuer." 

ADDITIONAL PURCHASE AND REDEMPTION INFORMATION 

In General

	Information on how to purchase and redeem each Fund's shares is 
included in the applicable Prospectus. The issuance of a Fund's 
shares is recorded on a Fund's books, and share certificates are not 
issued.

	The regulations of the Comptroller of the Currency (the 
"Comptroller") provide that funds held in a fiduciary capacity by a 
national bank approved by the Comptroller to exercise fiduciary 
powers must be invested in accordance with the instrument 
establishing the fiduciary relationship and local law. The Trust 
believes that the purchase of Municipal Money Market Fund or Tax-Free 
Money Market Fund shares by such national banks acting on behalf of 
their fiduciary accounts is not contrary to applicable regulations if 
consistent with the particular account and proper under the law 
governing the administration of the account. 

	Conflict of interest restrictions may apply to an institution's 
receipt of compensation paid by a Fund on fiduciary funds that are 
invested in a Fund's Class B, or Class C or Class E shares. 
Institutions, including banks regulated by the Comptroller and 
investment advisers and other money managers subject to the 
jurisdiction of the SEC, the Department of Labor or state securities 
commissions, are urged to consult their legal advisers before 
investing fiduciary funds in a Fund's Class B, Class C or Class E 
shares. 

	Under the 1940 Act, a Fund may suspend the right of redemption 
or postpone the date of payment upon redemption for any period during 
which the New York Stock Exchange ("NYSE") is closed, other than 
customary weekend and holiday closings, or during which trading on 
the NYSE is restricted, or during which (as determined by the SEC by 
rule or regulation) an emergency exists as a result of which disposal 
or valuation of portfolio securities is not reasonably practicable, 
or for such other periods as the SEC may permit. (A Fund may also 
suspend or postpone the recordation of the transfer of its shares 
upon the occurrence of any of the foregoing conditions.) In addition, 
a Fund may redeem shares involuntarily in certain other instances if 
the Board of Trustees determines that failure to redeem may have 
material adverse consequences to that Fund's investors in general. 
Each Fund is obligated to redeem shares solely in cash up to $250,000 
or 1% of such Fund's net asset value, whichever is less, for any one 
investor within a 90-day period. Any redemption beyond this amount 
will also be in cash unless the Board of Trustees determines that 
conditions exist which make payment of redemption proceeds wholly in 
cash unwise or undesirable. In such a case, a Fund may make payment 
wholly or partly in readily marketable securities or other property, 
valued in the same way as that Fund determines net asset value. See 
"Net Asset Value" below for an example of when such redemption or 
form of payment might be appropriate. Redemption in kind is not as 
liquid as a cash redemption. Shareholders who receive a redemption in 
kind may incur transaction costs, if they sell such securities or 
property, and may receive less than the redemption value of such 
securities or property upon sale, particularly where such securities 
are sold prior to maturity. 

	Any institution purchasing shares on behalf of separate accounts 
will be required to hold the shares in a single nominee name (a 
"Master Account"). Institutions investing in more than one of the 
Trust's portfolios or classes of shares must maintain a separate 
Master Account for each portfolio or class of shares. Sub-accounts 
may be established by name or number either when the Master Account 
is opened or later.

Net Asset Value

	Each Fund's net asset value per share is calculated separately 
for each class by dividing the total value of the assets belonging to 
such Fund attributable to a class, less the value of any class-
specific liabilities charged to such Fund, by the total number of 
that Fund's shares of that class outstanding.  "Assets belonging to" 
a Fund consist of the consideration received upon the issuance of 
Fund shares together with all income, earnings, profits and proceeds 
derived from the investment thereof, including any proceeds from the 
sale, exchange or liquidation of such investments, any funds or 
payments derived from any reinvestment of such proceeds and a portion 
of any general assets of the Trust not belonging to a particular 
Fund. Assets belonging to a Fund are charged with the direct 
liabilities of that Fund and with a share of the general liabilities 
of the Trust allocated on a daily basis in proportion to the relative 
net assets of that Fund and the Trust's other portfolios. 
Determinations made in good faith and in accordance with generally 
accepted accounting principles by the Trust's Board of Trustees as to 
the allocation of any assets or liabilities with respect to a Fund 
are conclusive. 

	As stated in the applicable Prospectus, in computing the net 
asset value of its shares for purposes of sales and redemptions, each 
Fund uses the amortized cost method of valuation. Under this method, 
a Fund values each of its portfolio securities at cost on the date of 
purchase and thereafter assumes a constant proportionate amortization 
of any discount or premium until maturity of the security. As a 
result, the value of a portfolio security for purposes of determining 
net asset value normally does not change in response to fluctuating 
interest rates. While the amortized cost method provides certainty in 
portfolio valuation, it may result in valuations of a Fund's 
securities which are higher or lower than the market value of such 
securities. 

	In connection with its use of amortized cost valuation, each 
Fund limits the dollar-weighted average maturity of its portfolio to 
not more than 90 days and does not purchase any instrument with a 
remaining maturity of more than 13 months (397 days) (with certain 
exceptions). The Trust's Board of Trustees has also established, 
pursuant to rules promulgated by the SEC, procedures that are 
intended to stabilize each Fund's net asset value per share for 
purposes of sales and redemptions at $1.00. Such procedures include 
the determination at such intervals as the Board deems appropriate, 
of the extent, if any, to which a Fund's net asset value per share 
calculated by using available market quotations deviates from $1.00 
per share. In the event such deviation exceeds 1/2 of 1%, the Board 
will promptly consider what action, if any, should be initiated. If 
the Board believes that the amount of any deviation from a Fund's 
$1.00 amortized cost price per share may result in material dilution 
or other unfair results to investors or existing shareholders, it 
will take such steps as its considers appropriate to eliminate or 
reduce to the extent reasonably practicable any such dilution or 
unfair results. These steps may include selling portfolio instruments 
prior to maturity to realize capital gains or losses or to shorten a 
Fund's average portfolio maturity, redeeming shares in kind, reducing 
or withholding dividends, or utilizing a net asset value per share 
determined by using available market quotations.

Distributor

	Lehman Brothers acts as the Distributor of each Fund's shares.  
Lehman Brothers, located at 3 World Financial Center, New York, New 
York 10285, is a wholly-owned subsidiary of Lehman Brothers Holdings 
Inc. ("Holdings").  As of December 31, 1995, FMR Corp. beneficially 
owned approximately 11.7%, Nippon Life Insurance Company beneficially 
owned approximately 5.0% and Prudential Asset Management beneficially 
owned approximately 5.0% of the outstanding voting securities of 
Holdings.  Each Fund's shares are sold on a continuous basis by 
Lehman Brothers.  The Distributor pays the cost of printing and 
distributing prospectuses to persons who are not investors of a Fund 
(excluding preparation and printing expenses necessary for the 
continued registration of a Fund's shares) and of preparing, printing 
and distributing all sales literature. No compensation is payable by 
a Fund to Lehman Brothers for its distribution services. 

	Lehman Brothers is comprised of several major operating business 
units. Lehman Brothers Institutional Funds Group is the business 
group within Lehman Brothers that is primarily responsible for the 
distribution and client service requirements of the Trust and its 
investors. Lehman Brothers Institutional Funds Group has been serving 
institutional clients' investment needs exclusively for more than 20 
years, emphasizing high quality individualized service to clients. 

Investment Adviser

	Lehman Brothers Global Asset Management, Inc. serves as the 
Investment Adviser to each of the Funds.  The Adviser, located at 3 
World Financial Center, New York, New York 10285, is a wholly-owned 
subsidiary of Holdings.  The investment advisory agreements provide 
that the Adviser is responsible for all investment activities of the 
Fund, including executing portfolio strategy, effecting Fund purchase 
and sale transactions and employing professional portfolio managers 
and security analysts who provide research for the Funds.

	Investment personnel of the Adviser may invest in securities for 
their own account pursuant to a code of ethics that establishes 
procedures for personal investing and restricts certain transactions. 

	The Investment Advisory Agreement with respect to each of the 
Funds was most recently approved by the Trust's Board of Trustees, 
including a majority of the Trust's "non-interested" Trustees, on 
December 5, 1995 and by shareholders on January 31, 1996.  The 
Investment Advisory Agreements commenced on February 1, 1996 and will 
continue until February 1, 1998 unless terminated or amended prior to 
that date according to its terms.  The Investment Advisory Agreements 
will continue initially for a two-year period and automatically for 
successive annual periods thereafter provided the continuance is 
approved annually (i) by the Trust's Board of Trustees or (ii) by a 
vote of a "majority" (as defined in the 1940 Act) of a Fund's 
outstanding voting securities, except that in either event the 
continuance is also approved by a majority of the Trustees of the 
Trust who are not "interested persons" (as defined in the 1940 Act). 
Each Investment Advisory Agreement may be terminated (i) on 60 days' 
written notice by the Trustees of the Trust, (ii) by vote of holders 
of a majority of a Fund's outstanding voting securities, or upon 90 
days' written notice by Lehman Brothers, or (iii) automatically in 
the event of its assignment (as defined in the 1940 Act).

	Effective February 1, 1996, as compensation for the Adviser's 
services rendered to the Fund, the Adviser is entitled to a fee, 
computed daily and paid monthly, at the annual rate of .20% of the 
average daily net assets of the Fund.  Prior to February 1, 1996, the 
Adviser was entitled to a fee, computed daily and paid monthly, at 
the annual rate of .10% of the average net assets of the Fund.  For 
the fiscal period ended January 31, 1994 and the fiscal years ended 
January 31, 1995 and 1996, the Adviser was entitled to receive 
advisory fees in the following amounts:  the Municipal Money Market 
Fund, $103,318, $223,512 and $172,515, respectively, and the Tax-Free 
Money Market Fund, $15,640, $59,392 and $76,037, respectively.  
Waivers by the Adviser of advisory fees and reimbursement of expenses 
to maintain the Funds' operating expense ratios at certain levels 
amounted to:  the Municipal Money Market Fund, $103,318 and $133,212, 
respectively, for the fiscal period ended January 31, 1994, $150,715 
and $0, respectively, for the fiscal year ended January 31, 1995 and 
$44,039 and $0.00, respectively, for the fiscal year ended January 
31, 1996; and the Tax-Free Money Market Fund $15,640 and $139,234, 
respectively for the fiscal period ended January 31, 1994, $59,392 
and $9,042, respectively, for the fiscal year ended January 31, 1995 
and $48,697 and $0.00, respectively, for the fiscal year ended 
January 31, 1996.  In order to maintain competitive expense ratios 
during 1996 and thereafter, the Adviser and Administrator have agreed 
to voluntary fee waivers and expense reimbursements for each of the 
Funds if total operating expenses exceed certain levels.  See 
"Background and Expense Information" in each Fund's Prospectus.

record.

	As of February 16, 1996, there were no investors in Class B, 
Class C, or Class E Shares of Tax-Free Money Market Fund and all 
outstanding shares were held by Lehman Brothers.

	The investors described above have indicated that they each hold 
their shares on behalf of various accounts and not as beneficial 
owners. To the extent that any investor is the beneficial owner of 
more than 25% of the outstanding shares of a Fund, such investor may 
be deemed to be a "control person" of that Fund for purposes of the 
1940 Act.

Administrator and Transfer Agent

	FDISG, a subsidiary of First Data Corporation, is located at One 
Exchange Place, Boston, Massachusetts 02109, and serves as the 
Trust's Administrator and Transfer Agent.  As the Trust's 
Administrator, FDISG has agreed to provide the following services: 
(i) assist generally in supervising a Fund's operations, providing 
and supervising the operation of an automated data processing system 
to process purchase and redemption orders, providing information 
concerning a Fund to its investors of record, handling investor 
problems, supervising the services of employees and monitoring the 
arrangements pertaining to a Fund's agreements with Service 
Organizations; (ii) prepare reports to the Funds' investors and 
prepare tax returns and reports to and filings with the SEC; 
(iii) compute the respective net asset value per share of each Fund; 
(iv) provide the services of certain persons who may be elected as

Trustees; and (v) maintain the registration or qualification of a 
Fund's shares for sale under state securities laws.  FDISG is 
entitled to receive, as compensation for its services rendered under 
an administration agreement, an administrative fee, computed daily 
and paid monthly, at the annual rate of .10% of the average daily net 
assets of each Fund.  FDISG pays Boston Safe Deposit and Trust 
Company ("Boston Safe"), the Fund's Custodian, a portion of its 
monthly administration fee for custody services rendered to the 
Funds.

	Prior to May 6, 1994, The Boston Company Advisors, Inc. 
("TBCA"), a wholly-owned subsidiary of Mellon Bank Corporation 
("Mellon"), served as Administrator of the Funds.  On May 6, 1994, 
FDISG acquired TBCA's third party mutual fund administration business 
from Mellon, and each Fund's administration agreement with TBCA was 
assigned to FDISG.  For the fiscal period ended January 31, 1994 and 
the fiscal years ended January 31, 1995 and 1996, the Administrator 
was entitled to receive administration fees in the following amounts:  
the Municipal Money Market Fund, $103,318, $223,512 and $172,515, 
respectively, and the Tax-Free Money Market Fund, $15,640, $59,392 
and $76,037, respectively.  Waivers by the Administrator of 
administration fees and reimbursement of expenses to maintain the 
Funds' operating expense ratios at certain levels amounted to:  the 
Municipal Money Market Fund, $103,318 and $28,669, respectively, for 
the fiscal period ended January 31, 1994, $171,438 and $0, 
respectively, for the fiscal year ended January 31, 1995, and 
$127,184 and $0.00, respectively, for the fiscal year ended January 
31, 1996; and the Tax-Free Money Market Fund, $15,640 and $10,485, 
respectively, for the fiscal period ended January 31, 1994, $44,947 
and $0, respectively, for the fiscal year ended January 31, 1995, and 
$56,170 and $0.00, respectively, for the fiscal year ended January 
31, 1996.  In order to maintain competitive expense ratios during 
1996 and thereafter, the Adviser and Administrator have agreed to 
reimburse the Funds if total operating expenses exceed certain 
levels.  See "Background and Expense Information" in each Fund's 
Prospectus.

	Under the transfer agency agreement, FDISG maintains the 
investor account records for the Trust, handles certain 
communications between investors and the Trust, distributes dividends 
and distributions payable by the Trust and produces statements with 
respect to account activity for the Trust and its investors. For 
these services, FDISG receives a monthly fee based on average net 
assets and is reimbursed for out-of-pocket expenses.

Custodian 

	Boston Safe, a wholly-owned subsidiary of Mellon, is located at 
One Boston Place, Boston, Massachusetts 02108, and serves as the 
Custodian of the Trust pursuant to a custody agreement. Under the 
custody agreement, Boston Safe holds each Fund's portfolio securities 
and keeps all necessary accounts and records. For its services, 
Boston Safe receives a monthly fee from FDISG based upon the 
month-end market value of securities held in custody and also 
receives securities transaction charges, including out-of-pocket 
expenses. The assets of the Trust are held under bank custodianship 
in compliance with the 1940 Act. 

Service Organizations

	As stated in the Funds' Prospectuses, a Fund will enter into an 
agreement with each financial institution which may purchase Class B, 
Class C or Class E shares.  The Fund will enter into an agreement 
with each Service Organization whose customers ("Customers") are the 
beneficial owners of Class B, Class C or Class E shares and that 
requires the Service Organization to provide certain services to 
Customers in consideration of such Fund's payment of  .25%, .35 or 
 .15%, respectively, of the average daily net asset value of the 
respective class held by the Service Organization for the benefit of 
Customers. Such services with respect to the Class C shares include:  
(i) aggregating and processing purchase and redemption requests from 
Customers and placing net purchase and redemption orders with a 
Fund's Distributor; (ii) processing dividend payments from a Fund on 
behalf of Customers; (iii) providing information periodically to 
Customers showing their positions in a Fund's shares; (iv) arranging 
for bank wires; (v) responding to Customer inquiries relating to the 
services performed by the Service Organization and handling 
correspondence; (vi) forwarding investor communications from a Fund 
(such as proxies, investor reports, annual and semi-annual financial 
statements, and dividend, distribution and tax notices) to Customers; 
(vii) acting as shareholder of record or nominee; and (viii) other 
similar account administrative services. In addition, a Service 
Organization at its option, may also provide to its Customers of 
Class C shares (a) a service that invests the assets of their 
accounts in shares pursuant to specific or pre-authorized 
instructions; (b) provide sub-accounting with respect to shares 
beneficially owned by Customers or the information necessary for sub-
accounting; and (c) provide checkwriting services.  Service 
Organizations that purchase Class C shares will also provide 
assistance in connection with the support of the distribution of 
Class C shares to its Customers, including marketing assistance and 
the forwarding to Customers of sales literature and advertising 
provided by the Distributor of the shares.  Holders of Class B shares 
of a Fund will receive the services set forth in (i) and (v) and may 
receive one or more of the services set forth in (ii), (iii), (iv), 
(vi), (vii) and (viii) above.  A Service Organization, at its option, 
may also provide to its Customers of Class B shares services 
including:  (a) providing Customers with a service that invests the 
assets of their accounts in shares pursuant to specific or pre-
authorized instruction; (b) providing sub-accounting with respect to 
shares beneficially owned by Customers or the information necessary 
for sub-accounting; (c) providing reasonable assistance in connection 
with the distribution of shares to Customers; and (d) providing such 
other similar services as the Fund may reasonably request to the 
extent the Service Organization is permitted to do so under 
applicable statutes, rules, or regulations.  Holders of Class E 
shares of a Fund will receive the services set forth in (i) and (v), 
above.  A Service Organization, at its option, may also provide to 
its Customers of Class E shares servicing including those services 
set forth in (ii), (iii), (iv), (vi), (vii) and (viii) above and the 
optional services set forth in (a), (b) and (c), above.

	Each Fund's agreements with Service Organizations are governed 
by a Shareholder Services Plan (the "Plan") that has been adopted by 
the Trust's Board of Trustees pursuant to an exemptive order granted 
by the SEC. Under this Plan, the Board of Trustees reviews, at least 
quarterly, a written report of the amounts expended under each Fund's 
agreements with Service Organizations and the purposes for which the 
expenditures were made. In addition, a Fund's arrangements with 
Service Organizations must be approved annually by a majority of the 
Trust's Trustees, including a majority of the Trustees who are not 
"interested persons" of the Trust as defined in the 1940 Act and have 
no direct or indirect financial interest in such arrangements (the 
"Disinterested Trustees").  

	The Board of Trustees has approved each Fund's arrangements with 
Service Organizations based on information provided by the Trust's 
service contractors that there is a reasonable likelihood that the 
arrangements will benefit such Fund and its investors by affording 
the Fund greater flexibility in connection with the servicing of the 
accounts of the beneficial owners of its shares in an efficient 
manner. Any material amendment to a Fund's arrangements with Service 
Organizations must be approved by a majority of the Trust's Board of 
Trustees (including a majority of the Disinterested Trustees). So 
long as a Fund's arrangements with Service Organizations are in 
effect, the selection and nomination of the members of the Trust's 
Board of Trustees who are not "interested persons" (as defined in the 
1940 Act) of the Trust will be committed to the discretion of such 
non-interested trustees. 

	For the fiscal year ended January 31, 1996, the following 
service fees were paid by Tax-Free Money Market Fund:  Class B 
shares, $0.00, Class C shares, $5,328.63, and Class E shares, $0.00.  
For the fiscal year ended January 31, 1995, the Tax-Free Money Market 
Fund paid $29 in service fees with respect to its Class B shares; no 
service fees were paid by the Fund with respect to Class C or Class E 
shares.  For the fiscal year ended January 31, 1996, the following 
service fees were paid by Municipal Money Market Fund:  Class B 
shares, $14.40, Class C shares, $0.00, and Class E shares, $0.00.  
For the fiscal year ended January 31, 1995, the Municipal Money 
Market Fund did not pay any service fees.  For the fiscal period 
ended January 31, 1994, neither Fund paid any service fees.

Expenses

	The Funds' expenses include taxes, interest, fees and salaries 
of the Trust's Trustees and Officers who are not directors, officers 
or employees of the Trust's service contractors, SEC fees, state 
securities qualification fees, costs of preparing and printing 
prospectuses for regulatory purposes and for distribution to 
investors, advisory, sub-advisory and administration fees, charges of 
the Administrator, Custodian and of the transfer and dividend 
disbursing agent, Service Organization fees, certain insurance 
premiums, outside auditing and legal expenses, costs of investor 
reports and shareholder meetings and any extraordinary expenses. The 
Funds also pay for brokerage fees and commissions (if any) in 
connection with the purchase and sale of portfolio securities.  The 
Adviser and FDISG have agreed that if, in any fiscal year, the 
expenses borne by a Fund exceed the applicable expense limitations 
imposed by the securities regulations of any state in which shares of 
that Fund are registered or qualified for sale to the public, they 
will reimburse the Fund for any excess to the extent required by such 
regulations. Unless otherwise required by law, such reimbursement 
would be accrued and paid on the same basis that the advisory and 
administration fees are accrued and paid by that Fund. To each Fund's 
knowledge, of the expense limitations in effect on the date of this 
Statement of Additional Information, none is more restrictive than 
two and one-half percent (2 1/2%) of the first $30 million of a 
Fund's average net assets, two percent (2%) of the next $70 million 
of the average annual net and one and one-half percent (1 1/2%) of 
the remaining average net assets.

ADDITIONAL INFORMATION CONCERNING TAXES 

	The following summarizes certain additional tax considerations 
generally affecting a Fund and its investors that are not described 
in the Funds' Prospectuses. No attempt is made to present a detailed 
explanation of the tax treatment of a Fund or its investors or 
possible legislative changes, and the discussion here and in the 
applicable Prospectus is not intended as a substitute for careful tax 
planning. Investors should consult their tax advisers with specific 
reference to their own tax situation.  

	As stated in each Prospectus, each Fund is treated as a separate 
corporate entity under the Code and qualified as a regulated 
investment company under the Code and intends to so qualify in future 
years. In order to so qualify for a taxable year, a Fund must satisfy 
the distribution requirement described in the Prospectuses, derive at 
least 90% of its gross income for the year from certain qualifying 
sources, comply with certain diversification requirements and derive 
less than 30% of its gross income for the year from the sale or other 
disposition of securities and certain other investments held for less 
than three months. Interest (including original issue discount and, 
with respect to taxable debt securities, accrued market discount) 
received by a Fund at maturity or disposition of a security held for 
less than three months will not be treated as gross income derived 
from the sale or other disposition of such security within the 
meaning of the 30% requirement. However, any other income which is 
attributable to realized market appreciation will be treated as gross 
income from the sale or other disposition of securities for this 
purpose. 

	As described above and in each Fund's Prospectus, each Fund is 
designed to provide institutions with current tax-exempt interest 
income. A Fund is not intended to constitute a balanced investment 
program and is not designed for investors seeking capital 
appreciation or maximum tax-exempt income irrespective of 
fluctuations in principal. Shares of a Fund would not be suitable for 
tax-exempt institutions and may not be suitable for retirement plans 
qualified under Section 401 of the Code, H.R. 10 plans and individual 
retirement accounts since such plans and accounts are generally 
tax-exempt and, therefore, not only would not gain any additional 
benefit from such Fund's dividends being tax-exempt but also such 
dividends would be taxable when distributed to the beneficiary. In 
addition, a Fund may not be an appropriate investment for entities 
which are "substantial users" of facilities financed by private 
activity bonds or "related persons" thereof. "Substantial user" is 
defined under U.S. Treasury Regulations to include a non-exempt 
person who regularly uses a part of such facilities in his or her 
trade or business and whose gross revenues derived with respect to 
the facilities financed by the issuance of bonds are more than 5% of 
the total revenues derived by all users of such facilities, or who 
occupies more than 5% of the usable area of such facilities or for 
whom such facilities or a part thereof were specifically constructed, 
reconstructed or acquired. "Related persons" include certain related 
natural persons, affiliated corporations, a partnership and its 
partners and an S Corporation and its shareholders. 

	In order for a Fund to pay exempt-interest dividends for any 
taxable year, at the close of each quarter of its taxable year at 
least 50% of the aggregate value of such Fund's assets must consist 
of exempt-interest obligations. After the close of its taxable year, 
a Fund will notify its investors of the portion of the dividends paid 
by such Fund which constitutes an exempt-interest dividend with 
respect to such taxable year. However, the aggregate amount of 
dividends so designated by a Fund cannot exceed the excess of the 
amount of interest exempt from tax under Section 103 of the Code 
received by that Fund for the taxable year over any amounts 
disallowed as deductions under Sections 265 and 171(a)(2) of the 
Code. The percentage of total dividends paid by a Fund with respect 
to any taxable year which qualifies as federal exempt-interest 
dividends will be the same for all investors of that Fund receiving 
dividends for such year. 

	Interest on indebtedness incurred by an investor to purchase or 
carry a Fund's shares is not deductible for federal income tax 
purposes if that Fund distributes exempt-interest dividends during 
the investor's taxable year. 

	While the Funds do not expect to realize long-term capital 
gains, any net realized long-term capital gains will be distributed 
at least annually. Each Fund will generally have no tax liability 
with respect to such gains, and the distributions will be taxable to 
each Fund's investors as long-term capital gains, regardless of how 
long a investor has held such Fund's shares. Such distributions will 
be designated as a capital gain dividend in a written notice mailed 
by the Fund to its investors not later than 60 days after the close 
of a Fund's taxable year. 

	Similarly, while the Funds do not expect to earn any investment 
company taxable income, taxable income earned by each Fund will be 
distributed to its investors. In general, a Fund's investment company 
taxable income will be its taxable income (for example, any 
short-term capital gains) subject to certain adjustments and 
excluding the excess of any net long-term capital gain for the 
taxable year over the net short-term capital loss, if any, for such 
year. A Fund will be taxed on any undistributed investment company 
taxable income of such Fund. To the extent such income is distributed 
by a Fund (whether in cash or additional shares), it will be taxable 
to that Fund's investors as ordinary income. 

	A 4% nondeductible excise tax is imposed on regulated investment 
companies that fail currently to distribute an amount equal to 
specified percentages of their ordinary taxable income and capital 
gain net income (excess of capital gains over capital losses). Each 
Fund intends to make sufficient distributions or deemed distributions 
of any ordinary taxable income and any capital gain net income prior 
to the end of each calendar year to avoid liability for  this excise 
tax. 

	If for any taxable year a Fund does not qualify for tax 
treatment as a regulated investment company, all of that Fund's 
taxable income will be subject to tax at regular corporate rates 
without any deduction for distributions to Fund investors. In such 
event, dividend distributions to investors would be taxable to 
investors to the extent of that Fund's earnings and profits, and 
would be eligible for the dividends received deduction for 
corporations. 

	Each Fund will be required in certain cases to withhold and 
remit to the U.S. Treasury 31% of taxable dividends or 31% of gross 
proceeds realized upon sale paid to its investors who have failed to 
provide a correct tax identification number in the manner required, 
or who are subject to withholding by the Internal Revenue Service for 
failure properly to include on their return payments of taxable 
interest or dividends, or who have failed to certify to a Fund that 
they are not subject to backup withholding when required to do so or 
that they are "exempt recipients." 

	Although each Fund expects to qualify each year as a "regulated 
investment company" and to be relieved of all or substantially all 
federal income taxes, depending upon the extent of its activities in 
states and localities in which its offices are maintained, in which 
its agents or independent contractors are located or in which they 
are otherwise deemed to be conducting business, a Fund may be subject 
to the tax laws of such states or localities. 

DIVIDENDS 

	Each Fund's net investment income for dividend purposes consists 
of (i) interest accrued and discount earned on that Fund's assets, 
(ii) less amortization of market premium on such assets, accrued 
expenses directly attributable to that Fund, and the general expenses 
(e.g., legal, accounting and trustees' fees) of the Trust prorated to 
such Fund on the basis of its relative net assets. The amortization 
of market discount on a Fund's assets is not included in the 
calculation of net income. 

	Realized and unrealized gains and losses on portfolio securities 
are reflected in net asset value. In addition, the Fund's Class B, 
Class C and Class E shares bear exclusively the expense of fees paid 
to Service Organizations with respect to the relevant Class of 
shares. See "Management of the Funds-Service Organizations." 

	As stated, the Trust uses its best efforts to maintain the net 
asset value per share of each Fund at $1.00. As a result of a 
significant expense or realized or unrealized loss incurred by a 
Fund, it is possible that a Fund's net asset value per share may fall 
below $1.00.

ADDITIONAL YIELD INFORMATION 

	The "yields,"  "effective yields" and "tax-equivalent yields" 
are calculated separately for each class of shares of each Fund and 
in accordance with the formulas prescribed by the SEC. The seven-day 
yield for each series of shares in a Fund is calculated by 
determining the net change in the value of a hypothetical preexisting 
account in such Fund which has a balance of one share of the class 
involved at the beginning of the period, dividing the net change by 
the value of the account at the beginning of the period to obtain the 
base period return, and multiplying the base period return by 365/7. 
The net change in the value of an account in a Fund includes the 
value of additional shares purchased with dividends from the original 
share and dividends declared on the original share and any such 
additional shares, net of all fees charged to all investor accounts 
in proportion to the length of the base period and the Fund's average 
account size, but does not include gains and losses or unrealized 
appreciation and depreciation. In addition, the effective yield 
quotations may be computed on a compounded basis (calculated as 
described above) by adding 1 to the base period return for the class 
involved, raising that sum to a power equal to 365/7, and subtracting 
1 from the result. A tax-equivalent yield for each class of a Fund's 
shares is computed by dividing the portion of the yield (calculated 
as above) that is exempt from federal income tax by one minus a 
stated federal income tax rate and adding that figure to that 
portion, if any, of the yield that is not exempt from federal income 
tax. Similarly, based on the calculations described above, 30-day (or 
one-month) yields, effective yields and tax-equivalent yields may 
also be calculated. 



	Based on the period ended January 31, 1996, the yields, effective yields and
 tax-equivalent yields 
for each of the Funds were as follows:

*estimated yield without fee waivers and/or expense reimbursements
Note:  Tax-equivalent yields assume a maximum Federal Tax Rate of 31%.

	Class B, Class C and Class E Shares bear the expenses of fees 
paid to Service Organizations. As a result, at any given time, the 
net yield of Class B, Class C and Class E Shares could be up to .25%, 
 .35% and .15% lower than the net yield of Class A Shares, 
respectively.  

	From time to time, in advertisements or in reports to investors, a Fund's yield
 may be quoted and 
compared to that of other money market funds or accounts with similar investment
 objectives and to stock 
or other relevant indices. For example, the yield of the Fund may be compared to
 the IBC/Donoghue's 
Money Fund Average, which is an average compiled by IBC/Donoghue's MONEY FUND
 REPORT of 
Holliston, MA 01746, a widely recognized independent publication that monitors
 the performance of 
money market funds, or to the average yields reported by the Bank Rate Monitor
 from money market 
deposit accounts offered by the 50 leading banks and thrift institutions in the
 top five standard metropolitan 
statistical areas. 

	Yields will fluctuate, and any quotation of yield should not be 
considered as representative of the future performance of a Fund. 
Since yields fluctuate, yield data for a Fund cannot necessarily be 
used to compare an investment in that Fund's shares with bank 
deposits, savings accounts and similar investment alternatives which 
often provide an agreed or guaranteed fixed yield for a stated period 
of time. Shareholders should remember that performance and yield are 
generally functions of the kind and quality of the investments held 
in a portfolio, portfolio maturity, operating expenses and market 
conditions. Any fees charged by banks with respect to customer 
accounts investing in shares of a Fund will not be included in yield 
calculations; such fees, if charged, would reduce the actual yield 
from that quoted. 

ADDITIONAL DESCRIPTION CONCERNING SHARES

	The Trust does not presently intend to hold annual meetings of 
shareholders except as required by the 1940 Act or other applicable 
law. The law under certain circumstances provides shareholders with 
the right to call for a meeting of shareholders to consider the 
removal of one or more Trustees. To the extent required by law, the 
Trust will assist in shareholder communication in such matters. 

	As stated in the Funds' Prospectuses, holders of shares in a 
Fund will vote in the aggregate and not by class or series on all 
matters, except where otherwise required by law and except that only 
a Fund's Class B, Class C and Class E shares, as the case may be, 
will be entitled to vote on matters submitted to a vote of 
shareholders pertaining to that Fund's arrangements with Service 
Organizations with respect to the relevant Class of shares. (See 
"Management of the Funds-Service Organizations.") Further, 
shareholders of all of the Trust's portfolios will vote in the 
aggregate and not by portfolio except as otherwise required by law or 
when the Board of Trustees determines that the matter to be voted 
upon affects only the interests of the shareholders of a particular 
portfolio. Rule 18f-2 under the 1940 Act provides that any matter 
required to be submitted by the provisions of such Act or applicable 
state law, or otherwise, to the holders of the outstanding securities 
of an investment company such as the Trust shall not be deemed to 
have been effectively acted upon unless approved by the holders of a 
majority of the outstanding shares of each portfolio affected by the 
matter. Rule 18f-2 further provides that a portfolio shall be deemed 
to be affected by a matter unless it is clear that the interests of 
each portfolio in the matter are identical or that the matter does 
not affect any interest of the portfolio. Under the Rule the approval 
of an investment advisory agreement or any change in a fundamental 
investment policy would be effectively acted upon with respect to a 
portfolio only if approved by the holders of a majority of the 
outstanding voting securities of such portfolio. However, the Rule 
also provides that the ratification of the selection of independent 
certified public accountants, the approval of principal underwriting 
contracts and the election of trustees are not subject to the 
separate voting requirements and may be effectively acted upon by 
shareholders of the investment company voting without regard to 
portfolio. 

COUNSEL 

	Willkie Farr & Gallagher, One Citicorp Center, New York, New 
York 10022, serves as counsel to the Trust and will pass upon the 
legality of the shares offered hereby. Willkie Farr & Gallagher also 
serves as counsel to Lehman Brothers. 

INDEPENDENT AUDITORS

	Ernst & Young LLP, independent auditors, serve as auditors to 
each Fund and render an opinion on each Fund's financial statements.  
Ernst & Young has offices at 200 Clarendon Street, Boston, 
Massachusetts 02116-5072.

FINANCIAL STATEMENTS

	The Trust's Annual Report for the fiscal year ended January 31, 
1995 and its Semi-Annual Report for the six-months ended July 31, 
1995 are incorporated into this Statement of Additional Information 
by reference in their entirety.

MISCELLANEOUS

Shareholder Vote

	As used in this Statement of Additional Information and the 
Funds' Prospectuses, a "majority of the outstanding shares" of a Fund 
or of any other portfolio means the lesser of (1) 67% of that Fund's 
shares (irrespective of class) or of the portfolio represented at a 
meeting at which the holders of more than 50% of the outstanding 
shares of that Fund or such portfolio are present in person or by 
proxy or (2) more than 50% of the outstanding shares of a Fund 
(irrespective of class) or of the portfolio. 

Shareholder and Trustee Liability

	The Trust is organized as a "business trust" under the laws of 
the Commonwealth of Massachusetts. Shareholders of such a trust may, 
under certain circumstances, be held personally liable (as if they 
were partners) for the obligations of the Trust. The Declaration of 
Trust of the Trust provides that shareholders shall not be subject to 
any personal liability for the acts or obligations of the Trust and 
that every note, bond, contract, order or other undertaking made by 
the Trust shall contain a provision to the effect that the 
shareholders are not personally liable thereunder. The Declaration of 
Trust provides for indemnification out of the trust property of a 
Fund of any shareholder of the Fund held personally liable solely by 
reason of being or having been a shareholder and not because of any 
acts or omissions or some other reason. The Declaration of Trust also 
provides that the Trust shall, upon request, assume the defense of 
any claim made against any shareholder for any act or obligation of 
the Trust and satisfy any judgment thereon. Thus, the risk of a 
shareholder incurring financial loss beyond the amount invested in a 
Fund on account of shareholder liability is limited to circumstances 
in which the Fund itself would be unable to meet its obligations. 

	The Trust's Declaration of Trust provides further that no 
Trustee of the Trust shall be personally liable for or on account of 
any contract, debt, tort, claim, damage, judgment or decree arising 
out of or connected with the administration or preservation of the 
trust estate or the conduct of any business of the Trust, nor shall 
any Trustee be personally liable to any person for any action or 
failure to act except by reason of bad faith, willful misfeasance, 
gross negligence in performing duties, or by reason of reckless 
disregard for the obligations and duties as Trustee. It also provides 
that all persons having any claim against the Trustees or the Trust 
shall look solely to the trust property for payment. With the 
exceptions stated, the Declaration of Trust provides that a Trustee 
is entitled to be indemnified against all liabilities and expenses 
reasonably incurred in connection with the defense or disposition of 
any proceeding in which the Trustee may be involved or may be 
threatened with by reason of being or having been a Trustee, and that 
the Trustees have the power, but not the duty, to indemnify officers 
and employees of the Trust unless such persons would not be entitled 
to indemnification if they were in the position of Trustee.


APPENDIX

DESCRIPTION OF MUNICIPAL OBLIGATION RATINGS

Commercial Paper Ratings

	Standard & Poor's, a division of The McGraw-Hill Companies 
("Standard & Poor's) commercial paper rating is a current assessment 
of the likelihood of timely payment of debt considered short-term in 
the relevant market.  The following summarizes the two highest rating 
categories used by Standard & Poor's for commercial paper: 

	"A-1" - Issue's degree of safety regarding timely payment is 
strong. Those issues determined to possess extremely strong safety 
characteristics are denoted "A-1+." 

	"A-2" - Issue's capacity for timely payment is satisfactory. 
However, the relative degree of safety is not as high as for issues 
designated "A-1." 

	Moody's short-term debt ratings are opinions of the ability of 
issuers to repay punctually senior debt obligations which have an 
original maturity not exceeding one year. The following summarizes 
the two highest rating categories used by Moody's for commercial 
paper: 

	"Prime-1" - Issuer or related supporting institutions are 
considered to have a superior ability for repayment of senior 
short-term debt obligations.  Principal repayment capacity will 
normally be evidenced by the following characteristics: leading 
market positions in well-established industries; high rates of return 
on funds employed; conservative capitalization structures with 
moderate reliance on debt and ample asset protection; broad margins 
in earning coverage of fixed financial charges and high internal cash 
generation; and well-established access to a range of financial 
markets and assured sources of alternate liquidity. 

	"Prime-2" - Issuer or related supporting institutions are 
considered to have a strong ability for repayment of senior 
short-term debt obligations.  This will normally be evidenced by many 
of the characteristics cited above but to a lesser degree. Earnings 
trends and coverage ratios, while sound, will be more subject to 
variation. Capitalization characteristics, while still appropriate, 
may be more affected by external conditions. Ample alternative 
liquidity is maintained. 

	The two highest rating categories of Duff & Phelps for 
investment grade commercial paper are "D-1" and "D-2." Duff & Phelps 
employs three designations, "D-1+," "D-1" and "D-1-," within the 
highest rating category. The following summarizes the two highest 
rating categories used by Duff & Phelps for commercial paper: 

	"D-1+" - Debt possesses highest certainty of timely payment. 
Short-term liquidity, including internal operating factors and/or 
access to alternative sources of funds, is outstanding, and safety is 
just below risk-free U.S. Treasury short-term obligations. 

	"D-1" - Debt possesses very high certainty of timely payment. 
Liquidity factors are excellent and supported by good fundamental 
protection factors. Risk factors are minor. 

	"D-1-" - Debt possesses high certainty of timely payment. 
Liquidity factors are strong and supported by good fundamental 
protection factors. Risk factors are very small. 

	"D-2" - Debt possesses good certainty of timely payment. 
Liquidity factors and company fundamentals are sound. Although 
ongoing funding needs may enlarge total financing requirements, 
access to capital markets is good. Risk factors are small. 

	Fitch short-term ratings apply to debt obligations that are 
payable on demand or have original maturities of generally up to 
three years. The two highest rating categories of Fitch for 
short-term obligations are "F-1" and "F-2." Fitch employs two 
designations, "F-1+" and "F-1," within the highest rating category. 
The following summarizes some of the rating categories used by Fitch 
for short-term obligations: 

	"F-1+" - Securities possess exceptionally strong credit quality. 
Issues assigned this rating are regarded as having the strongest 
degree of assurance for timely payment. 

	"F-1" - Securities possess very strong credit quality. Issues 
assigned this rating reflect an assurance of timely payment only 
slightly less in degree than issues rated "F-1+." 

	"F-2" - Securities possess good credit quality. Issues carrying 
this rating have a satisfactory degree of assurance for timely 
payment, but the margin of safety is not as great as the "F-1+" and 
"F-1" categories. 

	Fitch may also use the symbol "LOC" with its short-term ratings 
to indicate that the rating is based upon a letter of credit issued 
by a commercial bank. 

	Thomson BankWatch short-term ratings assess the likelihood of an 
untimely payment of principal or interest of debt having a maturity 
of one year or less.  The following summarizes the two highest 
ratings used by Thomson BankWatch: 

	"TBW-1" - This designation represents Thomson BankWatch's 
highest rating category and indicates a very high degree of 
likelihood that principal and interest will be paid on a timely 
basis. 

	"TBW-2" - This designation indicates that while the degree of 
safety regarding timely payment of principal and interest is strong, 
the relative degree of safety is not as high as for issues rated 
"TBW-1." 

	IBCA assesses the investment quality of unsecured debt with an 
original maturity of less than one year which is issued by bank 
holding companies and their principal bank subsidiaries. The highest 
rating category of IBCA for short-term debt is "A." IBCA employs two 
designations, "A1+" and "A1," within the highest rating category. The 
following summarizes the two highest rating categories used by IBCA 
for short-term debt ratings: 

	"A1" - Obligations are supported by the highest capacity for 
timely repayment.  Where issues possess a particularly strong credit 
feature a rating of "A1+" is assigned. 

	"A2" - Obligations are supported by a good capacity for timely 
repayment.



Municipal Long-Term Debt Ratings

	The following summarizes the ratings used by Standard & Poor's 
for municipal long-term debt: 

	"AAA" - This designation represents the highest rating assigned 
by Standard & Poor's to a debt obligation and indicates an extremely 
strong capacity to pay interest and repay principal. 

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

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

	"BBB" - Debt is regarded as having an adequate capacity to pay 
interest and repay principal.  Whereas such issues normally exhibit 
adequate protection parameters, adverse economic conditions or 
changing circumstances are more likely to lead to a weakened capacity 
to pay interest and repay principal for debt in this category than in 
higher-rated categories.

	"BB," "B," "CCC," "CC," and "C" - Debt that possesses one of 
these ratings is regarded as having predominantly speculative 
characteristics with respect to capacity to pay interest and repay 
principal.  "BB" indicates the least degree of speculation and "CCC" 
the highest degree of speculation.  While such debt will likely have 
some quality and protective characteristics, these are outweighed by 
large uncertainties or major risk exposures to adverse conditions.

	"CI" - This rating is reserved for income bonds on which no 
interest is being paid.

	"D" - Debt is in payment default.  This rating is also used upon 
the filing of a bankruptcy petition if debt service payments are 
jeopardized. 

	PLUS (+) or MINUS (-) - The rating of "AA" may be modified by 
the addition of a plus or minus sign to show relative standing within 
this rating category. 

	The following summarizes the ratings used by Moody's for 
municipal long-term debt:

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

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

	"A" - Bonds possess many favorable investment attributes and are 
to be considered as upper medium grade obligations.  Factors giving 
security to principal and interest are considered adequate but 
elements may be present which suggest a susceptibility to impairment 
sometime in the future.

	"Baa" - Bonds considered medium-grade obligations, i.e., they 
are neither highly protected nor poorly secured. Interest payments 
and principal security appear adequate for the present but certain 
protective elements may be lacking or may be characteristically 
unreliable over any great length of time. Such bonds lack outstanding 
investment characteristics and in fact have speculative 
characteristics as well.

	"Ba," "B," "Caa," "Ca," and "C" - Bonds that possess one of 
these ratings provide questionable protection of interest and 
principal ("Ba" indicates some speculative elements; "B" indicates a 
general lack of characteristics of desirable investment; "Caa" 
represents a poor standing; "Ca" represents obligations which are 
speculative in a high degree; and "C" represents the lowest rated 
class of bonds). "Caa," "Ca" and "C" bonds may be in default.

	Con. (---) - Municipal Bonds for which the security depends upon 
the completion of some act or the fulfillment of some condition are 
rated conditionally. These are bonds secured by (a) earnings of 
projects under construction, (b) earnings of projects unseasoned in 
operation experience, (c) rentals which begin when facilities are 
completed, or (d) payments to which some other limiting condition 
attaches. Parenthetical rating denotes probable credit stature upon 
completion of construction or elimination of basis of condition. 

	Moody's applies numerical modifiers 1, 2 and 3 in generic 
classification of "Aa" in its corporate bond rating system. The 
modifier 1 indicates that the company ranks in the higher end of its 
generic rating category; the modifier 2 indicates a mid-range 
ranking; and the modifier 3 indicates that the company ranks at the 
lower end of its generic rating category. 

	Those municipal bonds in the "Aa" to "B" groups which Moody's 
believes posses the strongest investment attributes are designated by 
the symbols "Aa1," "A1," "Baa1," "Ba1," and "B1." 

	The following summarizes the ratings used by Duff & Phelps for 
municipal long-term debt: 

	"AAA" - Debt is considered to be of the highest credit quality. 
The risk factors are negligible, being only slightly more than for 
risk-free U.S. Treasury debt. 

	"AA" - Debt is considered of high credit quality. Protection 
factors are strong. Risk is modest but may vary slightly from time to 
time because of economic conditions. 

	"A" - Debt possesses protection factors which are average but 
adequate.  However, risk factors are more variable and greater in 
periods of economic stress. 

	"BBB" - Debt possesses below average Protection factors but such 
protection factors are still considered sufficient for prudent 
investment.  Considerable variability in risk is present during 
economic cycles. 

	"BB," "B," "CCC," "DD," and "DP" - Debt that possesses one of 
these ratings is considered to be below investment grade.  Although 
below investment grade, debt rated "BB" is deemed likely to meet 
obligations when due.  Debt rated "B" possesses the risk that 
obligations will not be met when due. Debt rated "CCC" is well below 
investment grade and has considerable uncertainty as to timely 
payment of principal, interest or preferred dividends.  Debt rated 
"DD" is a defaulted debt obligation, and the rating "DP" represents 
preferred stock with dividend arrearages. 

	To provide more detailed indications of credit quality, the 
"AA," "A," "BBB," "BB" and "B" ratings may be modified by the 
addition of a plus (+) or minus (-) sign to show relative standing 
within these major rating categories. 

	The following summarizes the ratings used by Fitch for municipal 
bonds: 

	"AAA" - Bonds considered to be investment grade and of the 
highest credit quality. The obligor has an exceptionally strong 
ability to pay interest and repay principal, which is unlikely to be 
affected by reasonably foreseeable events. 

	"AA" - Bonds considered to be investment grade and of very high 
credit quality. The obligor's ability to pay interest and repay 
principal is very strong, although not quite as strong as bonds rated 
"AAA." Because bonds rated in the "AAA" and "AA" categories are not 
significantly vulnerable to foreseeable future developments, 
short-term debt of these issuers is generally rated "F-1+." 

	"A" - Bonds considered to be investment grade and of high credit 
quality.  The obligor's ability to pay interest and repay principal 
is considered to be strong, but may be more vulnerable to adverse 
changes in economic conditions and circumstances than bonds with 
higher ratings.

	"BBB" - Bonds considered to be investment grade and of 
satisfactory credit quality.  The obligor's ability to pay interest 
and repay principal is considered to be adequate.  Adverse changes in 
economic conditions and circumstances, however, are more likely to 
have an adverse impact on these bonds, and therefore, impair timely 
payment.  The likelihood that the ratings of these bonds will fall 
below investment grade is higher than for bonds with higher ratings. 

	"BB," "B," "CCC," "CC," "C," "DDD," "DD," and "D" -Bonds that 
possess one of these ratings are considered by Fitch to be 
speculative investments.  The ratings "BB" to "C" represent Fitch's 
assessment of the likelihood of timely payment of principal and 
interest in accordance with the terms of obligation for bond issues 
not in default.  For defaulted bonds, the rating "DDD" to "D" is an 
assessment that bonds should be valued on the basis of the ultimate 
recovery value in liquidation or reorganization of the obligor.

	To provide more detailed indications of credit quality, the 
Fitch ratings from and including "AA" to "C" may be modified by the 
addition of a plus (+) or minus (-) sign to show relative standing 
within these major rating categories. 

	Thomson BankWatch assesses the likelihood of an untimely 
repayment of principal or interest over the term to maturity of 
long-term debt and preferred stock which are issued by United States 
commercial banks, thrifts and non-bank banks; non-United States 
banks; and broker-dealers. The following summarizes the two highest 
rating categories used by Thomson BankWatch for long-term debt 
ratings: 

	"AAA" - This designation represents the highest category 
assigned by Thomson BankWatch to long-term debt and indicates that 
the ability to repay principal and interest on a timely basis is very 
high. 

	"AA" - This designation indicates a superior ability to repay 
principal and interest on a timely basis with limited incremental 
risk versus issues rated in the highest category. 

	"A" - This designation indicates the ability to repay principal 
and interest is strong.  Issues rated "A" could be more vulnerable to 
adverse developments (both internal and external) than obligations 
with higher ratings. 

	PLUS (+) or MINUS (-) - The ratings may include a plus or minus 
sign designation which indicates where within the respective category 
the issue is placed. 

	IBCA assesses the investment quality of unsecured debt with an 
original maturity of more than one year which is issued by bank 
holding companies and their principal bank subsidiaries. The 
following summarizes the two highest rating categories used by IBCA 
for long-term debt ratings: 

	"AAA" - Obligations for which there is the lowest expectation of 
investment risk. Capacity for timely repayment of principal and 
interest is substantial such that adverse changes in business, 
economic or financial conditions are unlikely to increase investment 
risk significantly. 

	"AA" - Obligations for which there is a very low expectation of 
investment risk. Capacity for timely repayment of principal and 
interest is substantial. Adverse changes in business, economic or 
financial conditions may increase investment risk albeit not very 
significantly. 

	"A" - Obligations for which there is a low expectation of 
investment risk.  Capacity for timely repayment of principal and 
interest is strong, although adverse changes in business economic or 
financial conditions may lead to increased investment risk. 

	IBCA may append a rating of plus (+) or minus (-) to a rating to 
denote relative status within these rating categories. 

Municipal Note Ratings

	A Standard & Poor's rating reflects the liquidity factors and 
market access risks unique to notes due in three years or less. The 
following summarizes the two highest rating categories used by 
Standard & Poor's Corporation for municipal notes: 

	SP-1" - The issuers of these municipal notes exhibit strong 
capacity to pay principal and interest. Those issues determined to 
possess a very strong capacity to pay are given a plus (+) 
designation.

	"SP-2" - The issuers of these municipal notes exhibit 
satisfactory capacity to pay principal and interest, with some 
vulnerability to adverse financial and economic changes over the term 
of the notes.

	Moody's ratings for state and municipal notes and other 
short-term loans are designated Moody's Investment Grade ("MIG"). 
Such ratings recognize the differences between short-term credit risk 
and long-term risk. A short-term rating may also be assigned on an 
issue having a demand feature.  Such ratings will be designated as 
"VMIG."  The following summarizes the two highest ratings used by 
Moody's Investors Service, Inc. for short-term notes: 

	"MIG-1"/"VMIG-1" - This designation denotes best quality.  There 
is strong protection by established cash flows, superior liquidity 
support or demonstrated broad-based access to the market for 
refinancing.

	"MIG-2"/"VMIG-2" - This designation denotes high quality.  
Margins of protection are ample although not so large as in the 
preceding group.

	Duff & Phelps and Fitch use the short-term ratings described 
under Commercial Paper Ratings for municipal notes.
