income with liquidity and security of principal. The Fund invests 
in those obligations issued or guaranteed as to principal and 
interest by the U.S. government or by agencies or

investors for certain services they provide to the beneficial 
owners of such shares. See "Management of the Fund_Service 
Organizations."

* 	The Expense Summary above has been restated to reflect 
current 
expected fees and the Fund's Investment Adviser's and 
Administrator's 
voluntary fee waivers and expense reimbursement arrangements in 
effect for 
the Fund's fiscal year ending January 31, 1995.




	In order to maintain a competitive expense ratio during 
1994, the Funds' Investment Adviser and Administrator have 
voluntarily agreed to waive fees and reimburse expenses if and to 
the extent that total operating expenses (other than taxes, 
interest, brokerage fees and commissions, Rule 12b-1 fees and 
extraordinary expenses) exceed .16% of average daily net assets 
through December 31, 1994. For 1995 and thereafter, the Investment 
Adviser and Administrator intend to continue voluntarily 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. 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 Investment 
Adviser and Administrator total .20% of average daily net assets. 
Absent fee waivers and reimbursement of expenses, the Total Fund 
Operating Expenses of Class A, Class B and Class C are expected to 
be .36%, .61% and .71%, respectively, of the Fund's average daily 
net assets.

INVESTMENT OBJECTIVE AND POLICIES

In General

	The Fund's investment objective is to provide current income 
with liquidity and security of principal. The Fund, which operates 
as a diversified investment company, invests in obligations issued 
or guaranteed as to principal and interest by the U.S. government 
or by agencies or instrumentalities thereof the interest income 
from which, under current law, generally may not be subject to 
state income tax by reason of federal law, including securities 
issued by the U.S. Treasury and by certain agencies or 
instrumentalities such as the Federal Home Loan Bank, Federal Farm 
Credit Banks Funding Corp. and the Student Loan Marketing 
Association. Investors in a particular state that imposes an 
income tax should determine through consultation with their own 
tax advisors whether such interest income, when distributed by the 
Fund, will be considered by the state to have retained exempt 
status, and whether the Fund's capital gain and other income, if 
any, when distributed will be subject to the state's income tax. 
See "Taxes." Due to state income tax considerations, the Fund will 
not enter into repurchase agreements. 

	The Fund invests only in securities that are purchased with 
and payable in U.S. dollars (i.e., U.S. dollar denominated 
securities) and that have (or, pursuant to regulations adopted by 
the Securities and Exchange Commission, are deemed to have) 
remaining maturities of 13 months or less at the date of purchase 
by the Fund. The Fund maintains a dollar-weighted average 
portfolio maturity of 90 days or less. 

	Securities issued or guaranteed by the U.S. government, its 
agencies and 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 such 
securities may vary during the period a shareholder owns shares of 
the Fund. The Fund may from time to time engage in portfolio 
trading for liquidity purposes, in order to enhance its yield or 
if otherwise deemed advisable. In selling portfolio securities 
prior to maturity, the Fund may realize a price higher or lower 
than that paid to acquire any given security, depending upon 
whether interest rates have decreased or increased since its 
acquisition. 

	The 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 
Fund 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 Fund expects that commitments to purchase 
when-issued securities will not exceed 25% of the value of its 
total assets absent unusual market conditions. The Fund does not 
intend to purchase when-issued securities for speculative purposes 
but only in furtherance of its investment objective. 

	There can be no assurance that the Fund will achieve its 
investment objective. 

Investment Limitations

	The Fund's investment objective and the policies described 
above may be changed by the Trust's Board of Trustees without a 
vote of shareholders. If there is a change in the investment 
objective, investors should consider whether the Fund remains an 
appropriate investment in light of their then current financial 
position and needs. The Fund's investment limitations summarized 
below may not be changed without the affirmative vote of the 
holders of a majority of its outstanding shares. (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 Objective and Policies.")

The Fund may not: 1.Borrow money except from banks for temporary 
purposes and then in an amount not exceeding 10% of the value of 
the Fund's total assets, or mortgage, pledge or hypothecate its 
assets except in connection with any such borrowing and in amounts 
not in excess of the lesser of the dollar amounts borrowed or 10% 
of the value of the Fund's total assets at the time of such 
borrowing. Additional investments will not be made when borrowings 
exceed 5% of the Fund's assets. 2.Make loans except that the Fund 
may purchase or hold debt obligations in accordance with its 
investment objective and policies. 

PURCHASE AND REDEMPTION OF SHARES

Purchase Procedures

	Shares of the Fund 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 by the Fund only on days on which 
both Lehman Brothers 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. Orders received prior to noon, 
Eastern time, for which payment has been received by Boston Safe 
Deposit and Trust Company ("Boston Safe"), the Fund's Custodian, 
will be executed at noon. Orders received between noon and 1:00 
P.M., Eastern time, will be executed at 1:00 P.M., Eastern time, 
if payment has been received by Boston Safe by 1:00 P.M., Eastern 
time, and will be executed at 4:00 P.M. if payment has been 
received by 4:00 P.M. Orders received after 1:00 P.M., and orders 
for which payment has not been received by 4:00 P.M., Eastern 
time, will not be accepted and notice thereof will be given to the 
institution placing the order. Payment for Fund shares may be made 
only in federal funds immediately available to Boston Safe. 
(Payment for orders which are not received or accepted by Lehman 
Brothers will be returned after prompt inquiry to the sending 
institution.) The Fund may in its discretion reject any order for 
shares. 

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

	Conflict of interest restrictions may apply to an 
institution's receipt of compensation paid by the Fund on 
fiduciary funds that are invested in Class B or Class C shares. 
See also "Management of the Fund_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 Securities and Exchange Commission, the 
Department of Labor or state securities commissions, should 
consult their legal advisers before investing fiduciary funds in 
Class B or Class C shares. 

	

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

Redemption Procedures

	Redemption orders must be transmitted to Lehman Brothers by 
telephone at 1-800-851-3134. Payment for redeemed shares for which 
a redemption order is received by Lehman Brothers prior to 
1:00 P.M., Eastern time, on a day that both Lehman Brothers and 
the Federal Reserve Bank of Boston are open for business is 
normally made in federal funds wired to the redeeming shareholder 
on the same business day. Payment for other redemption orders 
which are received after 1:00 P.M., Eastern time, is normally 
wired in federal funds on the next business day following 
redemption. 

	Shares are redeemed at the net asset value per share next 
determined after Lehman Brothers' receipt of the redemption order. 
While the Fund intends to use its best efforts to maintain its 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. To allow the Fund's Investment Adviser to manage the 
Fund 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. 

	The Fund reserves the right to wire redemption proceeds 
within seven days after receiving the redemption order if, in the 
judgment of the Investment Adviser, an earlier payment could 
adversely affect the Fund. The Fund 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 Fund 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." 

Valuation of Shares_Net Asset Value

	The Fund's net asset value per share for purposes of pricing 
purchase and redemption orders is determined by the Fund's 
Administrator as of noon, 1:00 P.M. and 4:00 P.M., Eastern time, 
on each weekday, with the exception of those holidays on which 
either Lehman Brothers or the Federal Reserve Bank of Boston is 
closed. Currently, one or both of these institutions 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, 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 the Fund is 
calculated by adding the value of all securities and other assets 
belonging to the Fund, subtracting liabilities and dividing the 
result by the total number of the Fund's outstanding shares. In 
computing net asset value, the Fund uses the amortized cost method 
of valuation as described in the Statement of Additional 
Information under "Additional Purchase and Redemption 
Information." The 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 the Trust's other 
investment portfolios. 

Other Matters

	Fund shares are sold and redeemed without charge by the 
Fund. 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 shares on behalf of its 
customers is responsible for transmitting orders to Lehman 
Brothers in accordance with its customer agreements. 

DIVIDENDS

	Investors of the Fund are entitled to dividends and 
distributions arising only from the net investment income and 
capital gains, if any, earned on its investments held by the Fund. 
The Fund's net investment income is declared daily as a dividend 
to shares held of record at the close of business on the day of 
declaration. Shares begin accruing dividends on the day the 
purchase order for the shares is effected 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 a shareholder's shares of a particular 
class. The Fund does 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 share of the Fund share, except that 
Class B and Class C shares bear all the expense of fees paid to 
Service Organizations. As a result, at any given time, the net 
yield on Class B and Class C shares will be .25% and .35%, 
respectively, lower than the net yield on Class A shares. 

	Institutional investors may elect to have their dividends 
reinvested in additional full and fractional shares of the same 
class 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 as the Fund's Distributor at 260 Franklin Street, 15th 
Floor, Boston, Massachusetts 02110-9624 and will become effective 
after its receipt by the Distributor with respect to dividends 
paid. 

	The Shareholder Services Group, Inc. ("TSSG"), 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
	The Fund qualified in its last taxable year and intends to 
qualify in future years as a "regulated investment company" under 
the Internal Revenue Code of 1986, as amended (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 the 
Fund distribute to its investors at least 90% of its investment 
company taxable income for such year. In general, the Fund's 
investment company taxable income will be its taxable income 
(including interest) 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. The 
Fund intends to distribute substantially all of its investment 
company taxable income each year. Such distributions will be 
taxable as ordinary income to the Fund's 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 the Fund's distributions will be eligible 
for the dividends received deduction for corporations. The Fund 
does not expect to realize long-term capital gains and, therefore, 
does not contemplate payment of any "capital gain dividends" as 
described in the Code. 

	Dividends declared in October, November or December of any 
year payable to investors of record on a specified date in such 
months will be deemed to have been received by the investors and 
paid by the Fund on December 31 of such year in the event such 
dividends are actually paid during January of the following year. 

	To the extent permissible by federal and state law, the Fund 
is structured to provide investors with income that is exempt or 
excluded from taxation at the state and local level. Substantially 
all dividends paid to investors residing in certain states will be 
exempt or excluded from state income tax. Many states, by statute, 
judicial decision or administrative action, have taken the 
position that dividends of a regulated investment company such as 
the Fund that are attributable to interest on obligations of the 
U.S. Treasury and certain U.S. government agencies and 
instrumentalities are the functional equivalent of interest from 
such obligations and are, therefore, exempt from state and local 
income taxes. Investors should be aware of the application of 
their state and local tax laws to investments in the Fund. 

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

MANAGEMENT OF THE FUND

	The business and affairs of the Fund 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 Fund, including agreements 
with its Distributor, Investment Adviser, Administrator, Custodian 
and Transfer Agent. The day-to-day operations of the Fund are 
delegated to the Fund's Investment Adviser and Administrator. The 
Statement of Additional Information relating to the Fund contains 
general background information regarding each Trustee and 
executive officer of the Trust. 

Distributor

	Lehman Brothers, located at Three World Financial Center, 
New York, New York 10285, is the Distributor of the Fund's shares. 
Lehman Brothers is a wholly-owned subsidiary of Lehman Brothers 
Holdings, Inc. ("Holdings").  Prior to May 31, 1994, all of the 
issued and outstanding common stock (representing 92% of the 
voting stock) of Holdings was held by American Express Company.  
On May 31, 1994, American Express distributed to holders of common 
stock of American Express all outstanding shares of common stock 
of Holdings.  As of May 31, 1994, Nippon Life Insurance Company 
owned 11.2% 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 Fund. 

Investment Adviser_Lehman Brothers Global Asset Management Inc.
	Lehman Brothers Global Asset Management Inc. ("LBGAM"), 
located at 3 World Financial Center, New York, New York 10285, 
serves as the Fund's Investment Adviser. LBGAM is a wholly owned 
subsidiary of Holdings. LBGAM, together with other Lehman Brother 
investment advisory affiliates, serves as Investment Adviser to 
investment companies and private accounts and has assets under 
management of approximately $15 billion as of March 31, 1994. 

	As Investment Adviser to the Fund, LBGAM will among other 
things, participate in the formulation of the Fund's investment 
policies, analyze economic trends affecting the Fund, and monitor 
and evaluate the Fund's investment objective and policies and the 
Fund's investment performance. For its services LBGAM is entitled 
to receive a monthly fee from the Fund at the annual rate of .10% 
of the value of the Fund's average daily net assets. For the 
period February 8, 1993 (commencement of operations) to 
January 31, 1994, LBGAM received no advisory fees from the Fund. 

Administrator and Transfer Agent_The Shareholder Service Group, 
Inc.

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

Custodian_Boston Safe Deposit and Trust Company

	Boston Safe, a wholly owned subsidiary of The Boston 
Company, Inc., located at One Boston Place, Boston, Massachusetts 
02108, serves as the Fund's Custodian. 

Service Organizations

	Financial institutions, such as banks, savings and loan 
associations and other such institutions ("Service Organizations") 
and/or institutional customers of Service Organizations may 
purchase Class B or Class C shares. These shares are identical in 
all respects to Class A shares except that they bear the fees 
described below and enjoy certain exclusive voting rights on 
matters relating to these fees. The Fund will enter into an 
agreement with each Service Organization whose customers 
("Customers") are the beneficial owners of Class B or Class C 
shares that requires the Service Organization to provide certain 
services to Customers in consideration of the Fund's payment of 
service fees at the annual rate of .25% or .35%, respectively of 
the average daily net asset value of the respective Class 
beneficially owned by Customers. Such services, which are 
described more fully in the Statement of Additional Information 
under "Management of the Fund_Service Organizations," may include 
aggregating and processing purchase and redemption requests from 
Customers and placing net purchase and redemption orders with 
Lehman Brothers; processing dividend payments from the Fund on 
behalf of Customers; providing information periodically to 
Customers showing their positions in shares; arranging for bank 
wires; responding to Customer inquiries relating to the services 
provided by the Service Organization and handling correspondence; 
acting as shareholder of record and nominee; and providing 
reasonable assistance in connection with the distribution of 
shares to Customers. Services provided with respect to Class B 
shares will generally be more limited than those provided with 
respect to Class C shares. Under the terms of the agreements, 
Service Organizations are required to provide to their Customers a 
schedule of any fees that they may charge Customers in connection 
with their investments in Class B or Class C shares. Class A 
shares are sold to financial institutions that have not entered 
into servicing agreements with the Fund in connection with their 
investments. A salesperson and any person entitled to receive 
compensation for selling or servicing shares of the Fund may 
receive different compensation for selling or servicing one Class 
of shares over another Class. 

Expenses

	The Fund bears all of its own expenses. The 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, Securities and Exchange Commission 
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, 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. The 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 during 1994, LBGAM and TSSG have agreed 
voluntarily to reimburse the Fund if and to the extent that the 
Fund's total operating expenses (other than taxes, interest, 
brokerage fees and commissions, Rule 12b-1 fees under the 1940 Act 
and extraordinary expenses) exceed .16% of average daily net 
assets through December 31, 1994. The Investment Adviser and 
Administrator intend to continue voluntarily to waive fees to the 
extent necessary to maintain an annualized expense ratio at a 
level no greater than .18% of average daily net assets thereafter. 
This voluntary reimbursement will not be changed unless investors 
are provided at least 60 days' advance notice. In addition, these 
service providers have agreed to reimburse the Fund to the extent 
required by applicable state law for certain expenses that are 
described in the Statement of Additional Information relating to 
the Fund. Any fees charged by Service Organizations or other 
institutional investors to their customers in connection with 
investments in Fund shares are not reflected in the Fund's 
expenses. 

YIELDS

	From time to time the "yields", "effective yields" and 
"tax-equivalent yields" for Class A, Class B and Class C shares 
may be quoted in advertisements or in reports to investors. Yield 
figures are based on historical earnings and are not intended to 
indicate future performance. The "yield" quoted in advertisements 
for a particular class or sub-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 week 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 or sub-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 the 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." Yield quotations are computed separately for each 
Class of shares. 

	The Fund's yields 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 IBC/Donoghue's Money Fund Report, The Wall 
Street Journal and The New York Times, reports prepared by Lipper 
Analytical Service, Inc. and publications of a local or regional 
nature. 

	The 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. Since holders of Class B or 
Class C shares bear the service fees for services provided by 
Service Organizations, the net yield on such shares can be 
expected at any given time to be lower than the net yield on 
Class A shares. 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 the Fund's 
expenses or yields. The methods used to compute the Fund's yields 
are described in more detail in the Statement of Additional 
Information. Investors may call 1-800-238-2560 (Class A shares 
code: 004; Class B shares code: 104; Class C shares code: 204) 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 offers thirteen portfolios: Prime Money Market Fund 
(Class A, Class B and Class C), Prime Value Money Market Fund 
(Class A, Class B, Class C and Class D), Government Obligations 
Money Market Fund (Class A, Class B, Class C and Class D) 100% 
Government Obligations Money Market Fund (Class A, Class B and 
Class C), Treasury Instruments Money Market Fund (Class A, Class B 
and Class C), Treasury Instruments Money Market Fund II (Class A, 
Class B and Class C), 100% Treasury Instruments Money Market Fund 
(Class A, Class B and Class C), Tax-Free Money Market Fund 
(Class A, Class B and Class C), Municipal Money Market Fund 
(Class A, Class B, Class C and Class D), California Municipal 
Money Market Fund (Class A, Class B and Class C), New York 
Municipal Money Market Fund (Class A, Class B and Class C), 
Floating Rate U.S. Government Fund (Premier and Select Shares) and 
Short Duration U.S. Government Fund (Premier and Select Shares). 
Shares of the New York Municipal Money Market Fund are not 
currently sold to the public. 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 on 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, 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 that only Class B or Class C shares, as the case 
may be, 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. 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. (See the Statement of Additional Information 
under "Miscellaneous" 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 Expense Summary above has been restated to reflect 
current expected fees and the Fund's Investment Adviser's and 
Administrator's voluntary fee waiver and expense reimbursement 
arrangements in effect for the Fund's fiscal year ending 
January 31, 1995. 



	In order to maintain a competitive expense ratio during 
1994, the Fund's Investment Adviser and Administrator have 
voluntarily agreed to waive fees and reimburse expenses if and to 
the extent that total operating expenses (other than taxes, 
interest, brokerage fees and commissions, Rule 12b-1 fees and 
extraordinary expenses) exceed .16% of average daily net assets 
through December 31, 1994. For 1995 and thereafter, the Investment 
Adviser and Administrator intend to continue voluntarily 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. The voluntary 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 Investment Adviser and 
Administrator total .20% of average daily  net assets. Absent fee 
waivers and reimbursement of expenses, the Total Fund Operating 
Expenses of Class A, Class B and Class C are expected to be .37%, 
.62% and .72%, respectively, of the Fund's average daily net 
assets.

INVESTMENT OBJECTIVE AND POLICIES

In General

	The Fund's investment objective is to provide investors with 
as high a level of current income exempt from federal income tax 
and, to the extent possible, from California state personal income 
tax as is consistent with relative stability of principal. All or 
a portion of the Fund's dividends may be a specific tax preference 
item for purposes of the federal individual and corporate 
alternative minimum taxes. 

	In pursuing its investment objective, the Fund, which 
operates as a non-diversified investment company, invests 
substantially all of its assets in debt obligations issued by or 
on behalf of the State of California and other states, territories 
and possessions of the United States, the District of Columbia and 
their respective authorities, agencies, instrumentalities and 
political sub-divisions, and tax-exempt derivative securities such 
as tender option bonds, participations, beneficial interests in 
trusts and partnership interests (collectively "Municipal 
Obligations"). Dividends paid by the Fund that are derived from 
interest on obligations that are exempt from taxation under the 
Constitution or statutes of California ("California Municipal 
Obligations") are exempt from regular federal income tax and 
California state personal income tax. California Municipal 
Obligations include municipal securities issued by the State of 
California and its political sub-divisions. Dividends derived from 
interest on Municipal Obligations other than California Municipal 
Obligations are exempt from federal income tax but may be subject 
to California state personal income tax. The Fund expects that, 
except during temporary defensive periods, the Fund's assets will 
be invested primarily in California Municipal Obligations, 
although the amount of the Fund's assets invested in such 
securities will vary from time to time. At least 50% of the Fund's 
assets must be invested in such obligations and Federal 
Obligations (as defined under "Taxes" below) at the close of each 
quarter of its taxable year so as to permit the Fund to pay 
dividends that are exempt from California state personal income 
tax. Dividends, regardless of their source, may be subject to 
local taxes. 

 Price and Portfolio Maturity.  The Fund will not knowingly 
purchase securities the interest on which is subject to regular 
federal income tax. (See, however, "Taxes" below concerning 
treatment of exempt-interest dividends paid by the Fund for 
purposes of the federal alternative minimum tax applicable to 
particular classes of investors.) Except during temporary 
defensive periods, the Fund will invest substantially all, but in 
no event less than 80%, of its total assets in Municipal 
Obligations with remaining maturities of thirteen months or less 
as determined in accordance with the rules of the Securities and 
Exchange Commission. The Fund maintains a dollar-weighted average 
portfolio maturity of 90 days or less. The Fund follows these 
policies to maintain a constant net asset value of $1.00 per 
share, although there is no assurance it can do so on a continuing 
basis. The Fund may hold uninvested cash reserves pending 
investment during temporary defensive periods, including when 
suitable tax-exempt obligations are unavailable. Uninvested cash 
reserves will not earn income. 

 Portfolio Quality and Diversification.  The Fund will purchase 
only Municipal Obligations which are "Eligible Securities" (as 
defined by the Securities and Exchange Commission) and which 
present minimal credit risks as determined by the Investment 
Adviser pursuant to guidelines approved by the Trust's Board of 
Trustees. Eligible Securities consist of (i) instruments that are 
rated at the time of purchase in one of the top two rating 
categories by at least two unaffiliated nationally recognized 
statistical rating organizations ("NRSROs"), (ii) instruments 
rated in one of the top two rating categories by one such NRSRO 
(if only one such organization rates the instrument), 
(iii) instruments issued by issuers with short-term debt having 
such ratings, and (iv) unrated instruments determined by the 
Investment Adviser, pursuant to procedures approved by the Board 
of Trustees, to be of comparable quality. The Appendix to the 
Statement of Additional Information includes a description of 
applicable NRSRO ratings. 

Investment Limitations

	There can be no assurance that the Fund will achieve its 
investment objective. The Fund's investment objective and the 
policies described herein may be changed by the Trust's Board of 
Trustees without the affirmative vote of the holders of a majority 
of the Fund's outstanding shares, except that the Fund's policy of 
investing at least 80% of its assets in Municipal Obligations and 
the following investment limitations are fundamental and may not 
be changed without such a vote of shareholders. (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 Objective and Policies.") 

	The Fund may not:

	1.	Borrow money except from banks for temporary purposes 
and then in amounts not exceeding 10% of the value of the Fund's 
assets; or mortgage, pledge or hypothecate its assets except in 
connection with any such borrowing and in amounts not in excess of 
the lesser of the dollar amounts borrowed or 10% of the value of 
the Fund's total assets at the time of such borrowing. Additional 
investments will not be made 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 purchase to be 
invested in the securities of issuers conducting their principal 
business activities in the same industry; provided that this 
limitation shall not apply to Municipal Obligations or 
governmental guarantees of Municipal Obligations; and provided 
further that, for the purpose of this limitation only, industrial 
development bonds that are considered to be issued by 
non-governmental users (see the third investment limitation below) 
shall not be deemed to be Municipal Obligations; and provided, 
further, that there is no limitation with respect to investments 
in U.S. government securities. 

	3.	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 (a) up to 50% of the 
value of the Fund's assets may be invested without regard to this 
5% limitation; provided that no more than 25% of the value of the 
Fund's assets are invested in the securities of any one issuer and 
(b) this 5% limitation does not apply to U.S. government 
securities. For purposes of this limitation, a security is 
considered to be issued by the governmental entity (or entities) 
whose assets and revenues back the security, or, with respect to a 
private activity bond that is backed only by the assets and 
revenues of a non-governmental user, by such non-governmental 
user. In certain circumstances, the guarantor of a guaranteed 
security may also be considered to be an issuer in connection with 
such guarantee, except that a guarantee of a security shall not be 
deemed to be a security issued by the guarantor when the value of 
all securities issued and guaranteed by the guarantor and owned by 
the Fund does not exceed 10% of the value of the Fund's total 
assets. 

	Opinions relating to the validity of Municipal Obligations 
and to the exemption of interest thereon from federal income tax 
(and, with respect to California Municipal Obligations, to the 
exemption of interest thereon from California state personal 
income tax) are rendered by bond counsel to the respective issuers 
at the time of issuance, and opinions relating to the validity of 
and the tax-exempt status of payments received by the Fund from 
tax-exempt derivatives are rendered by counsel to the respective 
sponsors of such derivatives. The Fund and its Investment Adviser 
will rely on such opinions and will not review independently the 
underlying proceedings relating to the issuance of Municipal 
Obligations, the creation of any tax-exempt derivatives or the 
bases for such opinions. 

Types of Municipal Obligations

	The two principal classifications of Municipal Obligations 
which may be held by the Fund 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 may include private activity bonds. Such bonds may be 
issued by or on behalf of public authorities to finance various 
privately operated facilities, and are not payable from the 
unrestricted revenues of the issuer. As a result, the credit 
quality of private activity bonds is frequently related directly 
to the credit standing of private corporations or other entities. 

	The Tax Reform Act of 1986 substantially revised provisions 
of prior law affecting the issuance and use of proceeds of certain 
tax-exempt obligations. A new definition of private activity bonds 
was applied to many types of bonds, including those which were 
industrial development bonds under prior law. Interest on private 
activity bonds is tax-exempt only if the bonds fall within certain 
defined categories of qualified private activity bonds and meet 
the requirements specified in those respective categories. The Act 
generally did not change the tax treatment of bonds issued to 
finance governmental operations. The changes generally apply to 
bonds issued after August 15, 1986, with certain transitional 
rule exemptions. As used in this Prospectus, the term "private 
activity bonds" also includes industrial development revenue bonds 
issued pursuant to the Internal Revenue Code of 1986, as amended. 

	The Fund's portfolio may also include "moral obligation" 
securities, which are normally issued by special purpose public 
authorities. If the issuer of moral obligation securities is 
unable to meet its debt service obligations from current revenues, 
it may draw on a reserve fund, the restoration of which is a moral 
commitment but not a legal obligation of the state or municipality 
that created the issuer. 

Other Investment Practices

	Municipal Obligations purchased by the Fund may include 
variable rate demand notes. Such notes may not be rated by credit 
rating agencies, but unrated notes purchased by the Fund will be 
determined by the Fund's Investment Adviser to be of comparable 
quality at the time of purchase to rated instruments purchasable 
by the Fund. Where necessary to ensure that a note is an Eligible 
Security, the Fund will require that the issuer's obligation to 
pay the principal of the note be backed by a conditional 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 Fund, the 
Fund may, upon the 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, in 
some instances, make it difficult for the Fund to dispose of a 
variable rate demand note if the issuer were to default on its 
payment obligation or during periods that the Fund is not entitled 
to exercise its demand rights, and the Fund could, for this or 
other reasons, suffer a loss to the extent of the default. While, 
in general, the Fund will invest only in securities that mature 
within thirteen months of purchase, the Fund may invest in 
variable rate demand notes which have nominal maturities in excess 
of thirteen months, if such instruments carry demand features that 
comply with conditions established by the Securities and Exchange 
Commission. 

	The Fund may also purchase Municipal Obligations 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 Fund 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 Fund expects that 
commitments to purchase when-issued securities will not exceed 25% 
of the value of its total assets absent unusual market conditions. 
The Fund does not intend to purchase when-issued securities for 
speculative purposes but only in furtherance of its investment 
objective. 

	In addition, the Fund may acquire "stand-by commitments" 
with respect to Municipal Obligations held in its portfolio. Under 
a stand-by commitment, a dealer agrees to purchase at the Fund's 
option specified Municipal Obligations at a specified price. The 
Fund will acquire stand-by commitments solely to facilitate 
portfolio liquidity and does not intend to exercise its rights 
thereunder for trading purposes. 

	The Fund 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 Fund's Investment 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 
Fund may purchase tender option bonds with different types of 
ownership, payment, credit and/or liquidity arrangements. 

	The Fund may acquire custodial receipts or certificates 
underwritten by securities dealers or banks that evidence 
ownership of future interest payments, principal payments or both, 
on certain municipal obligations. The underwriter of these 
certificates or receipts typically purchases municipal obligations 
and deposits the obligations in an irrevocable trust or custodial 
account with a custodian bank, which then issues receipts or 
certificates that evidence ownership of the periodic unmatured 
coupon payments and the final principal payment on the 
obligations. Although under the terms of a custodial receipt, the 
Fund would be typically authorized to assert its rights directly 
against the issuer of the underlying obligation, the Fund could be 
required to assert through the custodian bank those rights as may 
exist against the underlying issuer. Thus, in the event the 
underlying issuer fails to pay principal and/or interest when due, 
the Fund may be subject to delays, expenses and risks that are 
greater than those that would have been involved if the Fund had 
purchased a direct obligation of the issuer. In addition, in the 
event that the trust or custodial account in which the underlying 
security has been deposited is determined to be an association 
taxable as a corporation instead of a non-taxable entity, the 
yield on the underlying security would be reduced in recognition 
of any taxes paid. 

	The Fund may purchase from financial institutions tax-exempt 
participation interests in Municipal Obligations. A participation 
interest gives the 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. The 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 Obligation, plus accrued 
interest. The Fund will invest no more than 5% of its total assets 
in participation interests. 

	The Fund will not knowingly invest more than 10% of the 
value of its 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). 
The Fund 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"). The Fund 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 Fund 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 normally is 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 10% limitation on investment in illiquid 
securities. The Fund's Investment Adviser will monitor the 
liquidity of such restricted securities under the supervision of 
the Board of Trustees. See "Investment Objective and 
Policies_Additional Information and Investment Practices_Illiquid 
Securities" in the Statement of Additional Information. 

Risk Factors

	The Fund intends to follow the diversification standards set 
forth in the Investment Company Act of 1940, as amended (the "1940 
Act"), except to the extent, in the judgment of the Investment 
Adviser, that non-diversification is appropriate in order to 
maximize the percentage of the Fund's assets that are California 
Municipal Obligations. The investment return on a non-diversified 
portfolio typically is dependent upon the performance of a smaller 
number of issuers relative to the number of issuers held in a 
diversified portfolio. In the event of changes in the financial 
condition or in the market's assessment of certain issuers, the 
Fund's maintenance of large positions in the obligations of a 
small number of issuers may affect the value of the Fund's 
portfolio to a greater extent than that of a diversified 
portfolio. 

	Although the Fund does not presently intend to do so on a 
regular basis, it may invest more than 25% of its assets in 
Municipal Obligations the interest on which is paid solely from 
revenues on similar projects if such investment is deemed 
necessary or appropriate by the Fund's Investment Adviser. To the 
extent that the Fund's assets are concentrated in Municipal 
Obligations payable from revenues on similar projects, are issued 
by issuers located in California or are private activity bonds, 
the Fund will be subject to the particular risks presented by such 
state, projects and bonds to a greater extent than it would be if 
the Fund's assets were not so concentrated. 

	The Fund's ability to achieve its investment objective is 
dependent upon various factors, including the ability of the 
issuers of California Municipal Obligations to meet their 
continuing payment obligations with respect to the municipal 
obligations in a timely manner. Currently, the State of California 
and many other issuers of California Municipal Obligations are 
experiencing financial and budgetary problems which could affect 
their ability to meet their financial obligations in a timely 
manner. Any resulting reductions in the creditworthiness of 
issuers of California Municipal Obligations could adversely affect 
the market values and marketability of California Municipal 
Obligations, and, consequently, the net asset value of the Fund's 
portfolio. 

	On July 15, 1992 and July 6, 1992, respectively, Standard & 
Poor's Corporation and Moody's Investors Service, Inc., citing the 
State of California's deteriorating financial position, lowered 
their ratings of the State's general obligation bonds from AA and 
Aa2, respectively, to A+ and Aa, respectively. 

	Certain California constitutional amendments, legislative 
measures, executive orders, administrative regulations and voter 
initiatives could result in certain adverse consequences affecting 
California Municipal Obligations. Significant financial and other 
considerations relating to the Fund's investments in California 
Municipal Obligations are summarized in the Statement of 
Additional Information. 

	The value of the Fund's portfolio securities can be expected 
to vary inversely with changes in prevailing interest rates.

PURCHASE AND REDEMPTION OF SHARES

Purchase Procedures

	Shares of the Fund 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 by the Fund only on a day on which 
both Lehman Brothers 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. Orders received prior to noon, 
Eastern time (9:00 A.M., Pacific time), for which payment has been 
received by Boston Safe Deposit and Trust Company ("Boston Safe"), 
the Fund's Custodian, will be executed at noon. Orders received 
prior to noon for which payment is received between noon and 
4:00 P.M., Eastern time (1:00 P.M., Pacific time), will be 
executed at 4:00 P.M., Eastern time. Orders received after noon, 
and orders for which payment has not been received by 4:00 P.M., 
Eastern time (1:00 P.M., Pacific time), will not be accepted and 
notice thereof will be given to the institution placing the order. 
Payment for Fund shares may be made only in federal funds 
immediately available to Boston Safe. (Payment for orders which 
are not received or accepted by Lehman Brothers will be returned 
after prompt inquiry to the sending institution.) The Fund may in 
its discretion reject any order for shares. 

	The minimum aggregate initial investment by an institution 
in the investment portfolios that comprise the Trust is $1 million 
(with not less than $25,000 invested in any one investment 
portfolio offered by the Trust); 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. 

	Conflict of interest restrictions may apply to an 
institution's receipt of compensation paid by the Fund in 
connection with the investment of fiduciary funds in Class B or 
Class C shares. See also "Management of the Fund_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 Securities and 
Exchange Commission, the Department of Labor or state securities 
commissions, are urged to consult their legal advisers before 
investing in Class B or Class C shares. 

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

Redemption Procedures

	Redemption orders must be transmitted to Lehman Brothers by 
telephone at 1-800-851-3134. Payment for redeemed shares for which 
a redemption order is received by Lehman Brothers before noon, 
Eastern time (9:00 A.M., Pacific time) on a day that both Lehman 
Brothers and the Federal Reserve Bank of Boston are open for 
business is normally made in federal funds wired to the redeeming 
shareholder on the same business day. Payment for redeemed shares 
for which a redemption order is received by Lehman Brothers after 
noon, Eastern time (9:00 A.M., Pacific time), on such a business 
day is normally made in federal funds wired to the redeeming 
shareholder on the next business day following redemption. The 
Fund reserves the right to wire redemption proceeds within seven 
days after receiving the redemption order if, in the judgment of 
the investment adviser and/or sub-investment adviser, an earlier 
payment could adversely affect the Fund. 

	Shares are redeemed at the net asset value per share next 
determined after Lehman Brothers' receipt of the redemption order. 
While the Fund intends to use its best efforts to maintain its 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. To allow the Fund's Investment Adviser to manage the 
Fund 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. 

	The Fund reserves the right to wire redemption proceeds 
within seven days after receiving the redemption order if, in the 
judgement of the Investment Advisor, an earlier payment could 
adversely affect the Fund. The Fund shall have the right to redeem 
shares involuntarily 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 Fund may redeem 
shares involuntarily or suspend the right of redemption as 
permitted under the 1940 Act, or under certain special 
circumstances described in the Statement of Additional Information 
under "Additional Purchase and Redemption Information." 

Valuation of Shares_Net Asset Value

	The Fund's net asset value per share for purposes of pricing 
purchase and redemption orders is determined by the Fund's 
Administrator as of noon and 4:00 P.M., Eastern time (1:00 P.M., 
Pacific time) 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. Currently, one or both 
of these institutions are closed on 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 the Fund is 
calculated by adding the value of all securities and other assets 
belonging to the Fund, subtracting liabilities and dividing the 
result by the number of the Fund's outstanding shares. Portfolio 
securities are valued on the basis of amortized cost. Under this 
method, the Fund values a portfolio security at cost on the date 
of purchase and thereafter assumes a constant amortization of any 
discount or premium until maturity of the security. As a result, 
the value of the 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 periods during which 
values, as determined by amortized cost, are higher or lower than 
the amount the Fund would receive if it sold the securities. The 
Fund's net asset value for purposes of pricing purchase and 
redemption orders is determined independently of the net asset 
value of the shares of the Trust's other investment portfolios. 

Other Matters

	Fund shares are sold and redeemed without charge by the 
Fund. Institutional investors purchasing or holding Fund shares 
for their customers' 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 shares on behalf of its 
customers is responsible for transmitting orders to Lehman 
Brothers in accordance with its customer agreements. 

DIVIDENDS

	Investors of the Fund are entitled to dividends and 
distributions arising only from the net investment income and 
capital gains, if any, earned on investments held by the Fund. The 
Fund's net investment income is declared daily as a dividend to 
shares held of record at the close of business on the day of 
declaration. Shares begin accruing dividends on the day the 
purchase order for the shares is effected 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 Fund does 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 Class B and Class 
C shares bear all the expenses of fees paid to Service 
Organizations. As a result, at any given time, the net yield on 
Class B and Class C shares will be .25% and .35%, respectively, 
lower than the net yield on Class A shares. 

	Institutional investors may elect to have their dividends 
reinvested in additional full and fractional shares of the same 
class 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 the Fund's Distributor at 260 Franklin Street, 
15th Floor, Boston, Massachusetts 02110-9624, and will become 
effective with respect to dividends paid after its receipt by 
TSSG. 

	The Shareholder Services Group, Inc. ("TSSG"), 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 and California tax qualification. 

TAXES

	

	The Fund qualified in its last taxable year and intends to 
qualify in future years as a "regulated investment company" under 
the Internal Revenue Code of 1986, as amended (the "Code"). A 
regulated investment company is exempt from federal income and 
California franchise and income taxes on amounts distributed to 
its shareholders. Qualification as a regulated investment company 
under the Code for a taxable year requires, among other things, 
that the Fund distribute to its investors at least the sum of 90% 
of its exempt-interest income net of certain deductions and 90% of 
its investment company taxable income for such year. Dividends 
derived from exempt-interest income (known as "exempt-interest 
dividends") 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. (See the 
Statement of Additional Information under "Additional Information 
Concerning Taxes.") 

	The 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 their federal 
alternative minimum taxable income for purposes of determining 
liability (if any) for the 24% alternative minimum tax applicable 
to individuals and the 20% alternative minimum tax and the 
environmental tax applicable to corporations. Corporate investors 
must also take all exempt-interest dividends into account in 
determining certain adjustments for 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 or 
Railroad Retirement Act benefits should note that all 
exempt-interest dividends will be taken into account in 
determining the taxability of such benefits. 

	Dividends that are paid by the Fund to non-corporate 
investors and are derived from interest on California Municipal 
Obligations (as defined above) or Federal Obligations are also 
exempt from California state personal income tax. For this 
purpose, Federal Obligations are obligations the interest on which 
is excludable from gross income for state income tax purposes 
under the Constitution or laws of the United States. However, 
dividends paid to corporate investors subject to California state 
franchise tax or California state corporate income tax will be 
taxed as ordinary income to such investors, notwithstanding that 
all or a portion of such dividends is exempt from California state 
personal income tax. Moreover, to the extent that the Fund's 
dividends are derived from interest on debt obligations other than 
California Municipal Obligations or Federal Obligations, such 
dividends will be subject to California state personal income tax, 
even though such dividends may be exempt for federal income tax 
purposes. 

	Except as noted with respect to California state personal 
income tax, dividends and distributions paid to investors that are 
derived from income on Municipal Obligations may be taxable income 
under state or local law even though all or a portion of such 
distributions may be derived from interest on tax-exempt 
obligations that, if paid directly to investors, would be 
tax-exempt income. To the extent, if any, that dividends paid to 
investors are derived from taxable income or from long-term or 
short-term capital gains, such dividends will not be exempt from 
federal income tax or California state personal income tax, 
whether paid in the form of cash or additional shares, and may 
also be subject to other state and local taxes. 

	Dividends declared in October, November or December of any 
year payable to investors of record on a specified date in such 
months will be deemed to have been received by the investors and 
paid by the Fund on December 31 of such year in the event such 
dividends are actually paid during January of the following year. 

	Investors will be advised at least annually as to the 
federal income tax as well as the California state personal income 
tax, status and consequences of dividends and distributions made 
each year. 

	The foregoing is only a brief summary of some of the 
important tax considerations generally affecting the Fund and its 
investors. No attempt is made to present a detailed explanation of 
the federal, state or local income tax treatment of the Fund or 
its investors, and this discussion is not intended as a substitute 
for careful tax planning. Accordingly, potential investors in the 
Fund should consult their tax advisors with specific reference to 
their own tax situations.

MANAGEMENT OF THE FUND

	The business and affairs of the Fund 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 Fund, including agreements 
with its Distributor, Investment Adviser, Administrator, Custodian 
and Transfer Agent. The day-to-day operations of the Fund are 
delegated to the Fund's Investment Adviser and Administrator. The 
Statement of Additional Information relating to the Fund 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 the Fund's shares. 
Lehman Brothers is a wholly-owned subsidiary of Lehman Brothers 
Holdings Inc. ("Holdings"). Prior to May 31, 1994, all of the 
issued and outstanding common stock (representing 92% of the 
voting stock) of Holdings was held by American Express Company. On 
May 31, 1994, American Express distributed to holders of common 
stock of American Express all outstanding shares of common stock 
of Holdings. As of May 31, 1994, Nippon Life Insurance Company 
owned 11.2% of the outstanding voting securities of Holdings. 
Lehman Brothers, a leading full service investment firm, meets the

policies, analyze economic trends affecting the Fund, and monitor 
and evaluate the Fund's investment objective and policies and the 
Fund's investment performance. For its services LBGAM is entitled 
to receive a monthly fee from the Fund at the annual rate of .10% 
of the value of the Fund's average daily net assets. For the 
period February 8, 1993 (commencement of operations) to 
January 31, 1994, LBGAM received no advisory fees from the Fund. 

Administrator and Transfer Agent_The Shareholder Services Group, 
Inc.

	

	The Shareholder Services Group, Inc. ("TSSG"), located at 
One Exchange Place, 53 State Street, Boston, Massachusetts 02109, 
serves as the Fund's Administrator and Transfer Agent. TSSG is a

Custodian_Boston Safe Deposit and Trust Company

	Boston Safe, a wholly owned subsidiary of The Boston Company

serves as the Fund's Custodian. 

Service Organizations

	Financial institutions such as banks, savings and loan 
associations and other such institutions ("Service Organizations") 
and/or institutional customers of Service Organizations may 
purchase Class B or Class C shares. These shares are identical in 
all respects to Class A shares except that they bear the fees 
described below and enjoy certain exclusive voting rights on 
matters relating to these fees. The Fund will enter into an 
agreement with each Service Organization whose customers 
("Customers") are the beneficial owners of Class B or Class C 
shares that requires the Service Organization to provide certain 
services to Customers in consideration of the Fund's payment of 
service fees at the annual rate of .25% or .35%, respectively, of 
the average daily net asset value of the respective Class 
beneficially owned by the Customers. Such services, which are 
described more fully in the Statement of Additional Information 
under "Management of the Fund_Service Organizations," may 

include aggregating and processing purchase and redemption 
requests from Customers and placing net purchase and redemption 
orders with Lehman Brothers; processing dividend payments from the 
Fund on behalf of Customers; providing information periodically to 
Customers showing their positions in shares; arranging for bank 
wires; responding to Customer inquiries relating to the services 
provided by the Service Organization and handling correspondence; 
acting as shareholder of record and nominee; and providing 
reasonable assistance in connection with the distribution of 
shares to Customers. Services provided with respect to Class B 
shares will generally be more limited than those provided with 
respect to Class C shares. Under the terms of the agreements, 
Service Organizations are required to provide to their Customers a 
schedule of any fees that they may charge to their Customers in 
connection with their investments in Class B or Class C shares. 
Class A shares are sold to financial institutions that have not 
entered into such servicing agreements with the Fund in connection 
with its investments. A salesperson and any other person entitled 
to receive compensation for selling or servicing shares of the 
Fund may receive different compensation for selling or servicing 
one Class of shares over another Class. 

Expenses

	The Fund bears all of its own expenses. The 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, Securities and Exchange Commission 
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, 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. The 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 during 1994, LBGAM and TSSG have agreed 
voluntarily to reimburse the Fund if and to the extent that the 
Fund's total operating expenses (other than taxes, interest, 
brokerage fees and commissions, Rule 12b-1 fees under the 1940 Act 
and extraordinary expenses) exceed .16% of average daily net 
assets through December 31, 1994. The Investment Adviser and 
Administrator intend to continue voluntarily to waive fees to the 
extent necessary to maintain an annualized expense ratio at a 
level no greater than .18% of average daily net assets thereafter. 
This voluntary reimbursement will not be changed unless investors 
are provided at least 60 days' advance notice. In addition, these 
service providers have agreed to reimburse the Fund to the extent 
required by applicable state law for certain expenses that are 
described in the Statement of Additional Information relating to 
the Fund. Any fees charged by Service Organizations or other 
institutional investors to their customers in connection with 
investments in Fund shares are not reflected in the Fund's 
expenses. 

YIELDS

	

	From time to time the "yields," "effective yields" and 
"tax-equivalent yields" of its Class A, Class B and Class C shares 
may be quoted in advertisements or in reports to investors. Yield 
quotations are computed separately for each Class of shares. The 
"yield" quoted in advertisements for a particular class or 
sub-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 week is assumed to be generated each week 
over a 52-week 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 of Fund shares 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 the Fund's 
tax-free yield. It is calculated by increasing the Fund's yield 
(calculated as above) by the amount necessary to reflect the 
payment of federal and California income taxes at a stated rate. 
The "tax-equivalent yield" will always be higher than the "yield." 

	The Fund's yields 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, 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. For example, such data are reported in national 
financial publications such as IBC/Donoghue's Money Fund Report, 
Ibbotson Associates of Chicago, The Wall Street Journal and The 
New York Times, reports prepared by Lipper Analytical 
Services, Inc. and publications of a local or regional nature. 

	The 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. Since holders of Class B or 
Class C shares bear the service fees for services provided by 
Service Organizations, the net yield on such shares can be 
expected at any given time to be lower than the net yield on 
Class A shares. 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 the Fund's 
expenses or yields. The methods used to compute the Fund's yields 
are described in more detail in the Statement of Additional 
Information. Investors may call 1-800-238-2560 (Class A shares 
code: 010; Class B shares code: 110; Class C shares code: 210) to 
obtain current yield information. 

DESCRIPTION OF SHARES

	The Trust was organized as a Massachusetts business trust 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 classes of shares. 
The Trust is an open-end management investment company, which 
offers thirteen portfolios: Prime Money Market Fund (Class A, 
Class B and Class C), Prime Value Money Market Fund (Class A, 
Class B, Class C and Class D), Government Obligations Money Market 
Fund (Class A, Class B, Class C and Class D), 100% Government 
Obligations Money Market Fund (Class A, Class B and Class C), 
Treasury Instruments Money Market Fund (Class A, Class B and 
Class C), Treasury Instruments Money Market Fund II (Class A, 
Class B and Class C), 100% Treasury Instruments Money Market Fund 
(Class A, Class B and Class C), Tax-Free Money Market Fund 
(Class A, Class B and Class C), Municipal Money Market Fund 
(Class A, Class B, Class C and Class D), California Municipal 
Money Market Fund (Class A, Class B and Class C), New York 
Municipal Money Market Fund (Class A, Class B and Class C), 
Floating Rate U.S. Government Fund (Premier and Select Shares) and 
Short Duration U.S. Government Fund (Premier and Select Shares). 
Shares of the New York Municipal Money Market Fund are not 
currently sold to the public. 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 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, 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 that only Class B or Class C shares, as the case 
may be, 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. Further, 
shareholders of all of the Fund and of the Trust's other 
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 investors 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 Expense Summary above has been restated to reflect 
current expected fees and the Fund's Investment Adviser's and 
Administrator's voluntary fee waiver and expense reimbursement 
arrangements in effect for the Fund's fiscal year ending 
January 31, 1995.



	In order to maintain a competitive expense ratio during 
1994, the Fund's Investment Adviser and Administrator have 
voluntarily agreed to waive fees and reimburse expenses if and to 
the extent that total operating expenses (other than taxes, 
interest, brokerage fees and commissions, Rule 12b-1 fees and 
extraordinary expenses) exceed .16% of average daily net assets 
through December 31, 1994. For 1995 and thereafter, the Investment 
Adviser and Administrator intend to continue voluntarily 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. 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 Investment 
Adviser and Administrator total .20% of average daily net assets. 
Absent fee waivers, the Total Fund Operating Expenses of Class A, 
Class B and Class C are expected to be .25%, .50% and .60%, 
respectively, of the Fund's average daily net assets.

INVESTMENT OBJECTIVE AND POLICIES

In General

	The Fund's investment objective is to provide current income 
with liquidity and security of principal. The Fund, which operates 
as a diversified investment company, 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. The Fund 
invests only in securities which are purchased with and payable in 
U.S. dollars (i.e., U.S. dollar denominated securities) and which 
have (or, pursuant to regulations adopted by the Securities and 
Exchange Commission, are deemed to have) remaining maturities of 
12 months or less at the date of purchase by the Fund. The Fund 
maintains a dollar-weighted average portfolio maturity of 90 days 
or less. 

	The "instrumentalities" or "agencies" of the U.S. government 
the obligations of which may be purchased by the Fund include: the 
Central Bank for Cooperatives, Export-Import Bank of the United 
States, Farmers Home Administration, Federal Farm Credit Banks, 
Federal Financing Bank, Federal Home Loan Banks, Federal Home Loan 
Mortgage Corporation, Federal Housing Administration, Federal 
Intermediate Credit Banks, Federal Land Banks, Federal National 
Mortgage Association, Financing Corporation, General Services 
Administration, Government National Mortgage Association, Maritime 
Administration, Private Export Funding Corp., Resolution Trust 
Corporation, Small Business Administration, Student Loan Marketing 
Association, Tennessee Valley Authority, U.S. Postal Service and 
Washington, D.C. Armory Board. Some obligations issued or 
guaranteed by agencies or instrumentalities of the U.S. Government 
are backed by the full faith and credit of the United States; 
others are backed by the right of the issuer to borrow from the 
U.S. Treasury or are backed only by the credit of the agency or 
instrumentality issuing the obligation. 

	Securities issued or guaranteed by the U.S. government, its 
agencies and 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 such 
securities may vary during the period a shareholder owns shares of 
the Fund. Certain government securities held by the Fund may have 
remaining maturities exceeding 12 months if such securities 
provide for adjustments in their interest rates not less 
frequently than every 12 months. 

	The Fund may invest in zero coupon U.S. Treasury securities, 
which are Treasury notes and bonds that have been stripped of 
their unmatured interest coupons, the coupons themselves and 
receipts or certificates representing interests in such stripped 
debt obligations and coupons. A zero coupon security pays no 
interest to its holder during its life and is sold at a discount 
to its face value at maturity. The amount of the discount 
fluctuates with the market price of the security. The market 
prices of zero coupon securities generally are more volatile than 
the market prices of securities that pay interest periodically and 
are likely to respond to a greater degree to changes in interest 
rates than non-zero coupon securities having similar maturities 
and credit qualities. Although zero coupon securities do not make 
interest payments, for tax purposes a portion of the difference 
between a zero coupon security's maturity value and its purchase 
price is taxable income of the Fund each year and distributed to 
Fund shareholders. Distributions to shareholders with respect to 
taxable income on zero coupon securities will reduce cash 
available for the purchase of income producing securities. 

	The Fund may purchase government securities from financial 
institutions, such as banks and broker-dealers, subject to the 
seller's agreement to repurchase them at an agreed upon time and 
price ("repurchase agreements"). The securities subject to a 
repurchase agreement may bear maturities exceeding 12 months, 
provided the repurchase agreement itself matures in one year or 
less. The Fund will not invest more than 10% of the value of its 
net assets in repurchase agreements which do not provide for 
settlement within 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 Fund to possible loss because of 
adverse market action or delay in connection with the disposition 
of the underlying obligations. 

	The 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 Fund would sell portfolio securities to financial 
institutions and agree to repurchase them at an agreed upon date 
and price. The Fund would consider entering into reverse 
repurchase agreements to avoid otherwise selling securities during 
unfavorable market conditions to meet redemptions. Reverse 
repurchase agreements involve the risk that the market value of 
the portfolio securities sold by the Fund may decline below the 
price of the securities the Fund is obligated to repurchase. 

	The 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 
Fund 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 Fund expects that commitments to purchase 
when-issued securities will not exceed 25% of the value of its 
total assets absent unusual market conditions. The Fund does not 
intend to purchase when-issued securities for speculative purposes 
but only in furtherance of its investment objective. 

	The Fund may also lend its portfolio securities to financial 
institutions in accordance with the investment restrictions 
described below. The Fund may lend portfolio securities against 
collateral consisting of cash or securities which are consistent 
with the Fund's permitted investments, which is equal at all times 
to at least 100% of the value of the securities loaned. There is 
no limitation on the amount of securities that may be loaned. Such 
loans would involve risks of delay in receiving additional 
collateral or in recovering the securities loaned or even loss of 
rights in the collateral should the borrower of the securities 
fail financially. However, loans will be made only to borrowers 
deemed by the Fund's Investment Adviser to be of good standing and 
only when, in the adviser's judgment, the income to be earned from 
the loans justifies the attendant risks. 

	There can be no assurance that the Fund will achieve its 
investment objective. 

Investment Limitations

	The Fund's investment objective and policies described above 
are not fundamental and may be changed by the Trust's Board of 
Trustees without a vote of shareholders. If there is a change in 
the investment objective, investors should consider whether the 
Fund remains an appropriate investment in light of their then 
current financial position and needs. The Fund's borrowing 
limitation summarized below may not be changed without the 
affirmative vote of the holders of a majority of its outstanding 
shares. (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 Objective 
and Policies.") 

	The Fund may not borrow money except from banks for 
temporary purposes and then in an amount not exceeding 10% of the 
value of the Fund's total assets, or mortgage, pledge or 
hypothecate its assets except in connection with any such 
borrowing and in amounts not in excess of the lesser of the dollar 
amounts borrowed or 10% of the value of the Fund's total assets at 
the time of such borrowing. Additional investments will not be 
made when borrowings exceed 5% of the Fund's assets.

PURCHASE AND REDEMPTION OF SHARES

Purchase Procedures

	Shares of the Fund 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 by the Fund only on days on which 
both Lehman Brothers and the Federal Reserve Bank of Boston are 
open for business and must be transmitted to Lehman Brothers, by 
telephone at 800-851-3134. Orders received prior to noon, Eastern 
time, for which payment has been received by Boston Safe Deposit 
and Trust Company ("Boston Safe"), the Fund's Custodian, will be 
executed at noon. Orders received between noon and 3:00 P.M., 
Eastern time, will be executed at 3:00 P.M., Eastern time, if 
payment has been received by Boston Safe by 3:00 P.M. and will be 
executed at 4:00 P.M. if payment has been received by 4:00 P.M. 
Orders received after 3:00 P.M., and orders for which payment has 
not been received by 4:00 P.M., Eastern time, will not be accepted 
and notice thereof will be given to the institution placing the 
order. Payments for Fund shares may be made only in federal funds 
immediately available to Boston Safe. (Payment for orders which 
are not received or accepted by Lehman Brothers will be returned 
after prompt inquiry to the sending institution.) The Fund may in 
its discretion reject any order for shares. 

	 The minimum aggregate initial investment by an institution 
in the investment portfolios that comprise the Trust is $1 million 
(with not less than $25,000 invested in any one investment 
portfolio offered by the Trust); 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. 

	Conflict of interest restrictions may apply to an 
institution's receipt of compensation paid by the Fund on 
fiduciary funds that are invested in Class B or Class C shares. 
See also "Management of the Fund_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 Securities and Exchange Commission, the 
Department of Labor or state securities commissions, are urged to 
consult their legal advisers before investing fiduciary funds in 
Class B or Class C shares. 

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

Redemption Procedures

	Redemption orders must be transmitted to Lehman Brothers by 
telephone at 1-800-851-3134. Payment for redeemed shares for which 
a redemption order is received by Lehman Brothers before 
3:00 P.M., Eastern time, on a day that both Lehman Brothers and 
the Federal Reserve Bank of Boston are open for business is 
normally made in federal funds wired to the redeeming shareholder 
on the same business day. Payment for other redemption orders 
which are received between 3:00 P.M. and 4:00 P.M., Eastern time, 
is normally wired in federal funds on the next business day 
following redemption. 

	Shares are redeemed at the net asset value per share next 
determined after Lehman Brothers' receipt of the redemption order. 
While the Fund intends to use its best efforts to maintain its 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. To allow the Fund's Investment Adviser to manage the 
Fund 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. 

	The Fund reserves the right to wire redemption proceeds 
within seven days after receiving the redemption order if, in the 
judgment of the Investment Adviser, an earlier payment could 
adversely affect the Fund. The Fund 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 Fund 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." 

Valuation of Shares_Net Asset Value

	The Fund's net asset value per share for purposes of pricing 
purchase and redemption orders is determined by the Fund's 
Administrator as of noon, 3:00 P.M. and 4:00 P.M., Eastern time, 
on each weekday, with the exception of those holidays on which 
either Lehman Brothers or the Federal Reserve Bank of Boston is 
closed. Currently, one or both of these institutions 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 the Fund 
is calculated by adding the value of all securities and other 
assets of the Fund, subtracting liabilities and dividing the 
result by the total number of the Fund's outstanding shares 
(irrespective of class or sub-class). In computing net asset 
value, the Fund uses the amortized cost method of valuation as 
described in the Statement of Additional Information under 
"Additional Purchase and Redemption Information." The 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 the Trust's other investment portfolios. 

Other Matters

	Fund shares are sold and redeemed without charge by the 
Fund. 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 shares on behalf of its 
customers is responsible for transmitting orders to Lehman 
Brothers in accordance with its customer agreements. 

DIVIDENDS

	

	Investors of the Fund are entitled to dividends and 
distributions arising only from the net investment income and 
capital gains, if any, earned on its investments. The Fund's net 
investment income is declared daily as a dividend to its 
shareholders of record at the close of business on the day of 
declaration. Shares begin accruing dividends on the day the 
purchase order for the shares is effected 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 Fund does 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 Class B and 
Class C shares bear all the expense of fees paid to Service 
Organizations. As a result, at any given time, the net yield on 
Class B and Class C shares will be .25% and .35%, respectively, 
lower than the net yield on Class A shares. 

	Institutional investors may elect to have their dividends 
reinvested in additional full and fractional shares of the same 
class 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 the Fund's Distributor, 260 Franklin Street, 15th 
Floor, Boston, Massachusetts 02110-9624, and will become effective 
after its receipt by the Distributor with respect to dividends 
paid. 

	The Shareholder Services Group, Inc. ("TSSG"), 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

	

	The Fund qualified in its last taxable year and intends to 
qualify in future years as a "regulated investment company" under 
the Internal Revenue Code of 1986, as amended (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 the 
Fund distribute to its investors at least 90% of its investment 
company taxable income for such year. In general, the Fund's 
investment company taxable income will be its taxable income 
(including interest) 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. The 
Fund intends to distribute substantially all of its investment 
company taxable income each year. Such distributions will be 
taxable as ordinary income to the Fund's 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 the Fund's distributions will be eligible 
for the dividends received deduction for corporations. The Fund 
does not expect to realize long-term capital gains and therefore 
does not expect to distribute any "capital gain dividends" as 
described in the Code. 

	Dividends declared in October, November or December of any 
year payable to investors of record on a specified date in such 
months will be deemed to have been received by the investors and 
paid by the Fund on December 31 of such year in the event such 
dividends are actually paid during January of the following year. 

	Many states, by statute, judicial decision or administrative 
action, have taken the position that dividends of a regulated 
investment company such as the Fund that are attributable to 
interest on obligations of the U.S. Treasury and certain U.S. 
government agencies and instrumentalities are the functional 
equivalent of interest from such obligations and are, therefore, 
exempt from state and local income taxes. 

	The Fund will provide investors annually with information 
about the portion of dividends from the Fund derived from U.S. 
Treasury and U.S. government agency obligations. Investors should 
be aware of the application of their state and local tax laws to 
investments in the Fund. 

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

MANAGEMENT OF THE FUND

	The business and affairs of the Fund 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 Fund, including agreements 
with its Distributor, Investment Adviser, Administrator, Custodian 
and Transfer Agent. The day-to-day operations of the Fund are 
delegated to the Fund's Investment Adviser and Administrator. The 
Statement of Additional Information relating to the Fund 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 the Fund's shares. 
Lehman Brothers is a wholly-owned subsidiary of Lehman Brothers 
Holdings Inc. ("Holdings"). Prior to May 31, 1994, all of the 
issued and outstanding common stock (representing 92% of the 
voting stock) of Holdings was held by American Express Company. On 
May 31, 1994, American Express distributed to holders of common 
stock of American Express all outstanding shares of common stock 
of Holdings. As of May 31, 1994, Nippon Life Insurance Company 
owned 11.2% 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 Fund. 

Investment Adviser_Lehman Brothers Global Asset Management Inc.

	Lehman Brothers Global Asset Management Inc. ("LBGAM"), 
located at 3 World Financial Center, New York, New York 10285, 
serves as the 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 $15 billion as of March 31, 1994. 

	As Investment Adviser to the Fund, LBGAM will among other 
things, participate in the formulation of the Fund's investment 
policies, analyze economic trends affecting the Fund, and monitor 
and evaluate the Fund's investment objective and policies and the 
Fund's investment performance.  For its services LBGAM is entitled 
to receive a monthly fee from the Fund at the annual rate of .10% 
of the value of the Fund's average daily net assets. For the 
period February 8, 1993 (commencement of operations) to 
January 31, 1994, LBGAM received no advisory fees from the Fund. 

Administrator and Transfer Agent_The Shareholder Services Group, 
Inc.

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

Custodian_Boston Safe Deposit and Trust Company

	Boston Safe, a wholly owned subsidiary of The Boston 
Company, Inc., located at One Boston Place, Boston, Massachusetts 
02108, serves as the Fund's Custodian. 

Service Organizations

	Financial institutions, such as banks, savings and loan 
associations and other such institutions ("Service Organizations") 
and/or institutional customers of Service Organizations may 
purchase Class B or Class C shares. These shares are identical in 
all respects to Class A shares except that they bear the fees 
described below and enjoy certain exclusive voting rights on 
matters relating to these fees. The Fund will enter into an 
agreement with each Service Organization whose customers 
("Customers") are the beneficial owners of Class B or Class C 
shares that requires the Service Organization to provide certain 
services to Customers in consideration of the Fund's payment of 
service fees at the annual rate of .25% or .35%, respectively, of 
the average daily net asset value of the respective Class 
beneficially owned by the Customers. Such services, which are 
described more fully in the Statement of Additional Information 
under "Management of the Fund_Service Organizations," may include 
aggregating and processing purchase and redemption requests from 
Customers and placing net purchase and redemption orders with 
Lehman Brothers; processing dividend payments from the Fund on 
behalf of Customers; providing information periodically to 
Customers showing their positions in shares; arranging for bank 
wires; responding to Customer inquiries relating to the services 
provided by the Service Organization and handling correspondence; 
acting as shareholder of record and nominee; and providing 
reasonable assistance in connection with the distribution of 
shares to Customers. Services provided with respect to Class B 
shares will generally be more limited than those provided with 
respect to Class C shares. Under the terms of the agreements, 
Service Organizations are required to provide to their Customers a 
schedule of any fees that they may charge to the Customers in 
connection with their investment in Class B or Class C shares. 
Class A shares are sold to financial institutions that have not 
entered into servicing agreements with the Fund in connection with 
their investments. A salesperson and any other person entitled to 
receive compensation for selling or servicing shares of the Fund 
may receive different compensation for selling or servicing one 
Class of shares over another Class. 

Expenses

	The Fund bears all of its own expenses. The 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, Securities and Exchange Commission 
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, 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. The 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 during 1994, LBGAM and TSSG have agreed 
voluntarily to reimburse the Fund if and to the extent that the 
Fund's total operating expenses (other than taxes, interest, 
brokerage fees and commissions, Rule 12b-1 fees under the 1940 Act 
and extraordinary expenses) exceed .16% of average daily net 
assets through December 31, 1994. The Investment Adviser and 
Administrator intend to continue voluntarily to waive fees to the 
extent necessary to maintain an annualized expense ratio at a 
level no greater than .18% of average daily net assets thereafter. 
This voluntary reimbursement will not be changed unless investors 
are provided at least 60 days' advance notice. In addition, these 
service providers have agreed to reimburse the Fund to the extent 
required by applicable state law for certain expenses that are 
described in the Statement of Additional Information relating to 
the Fund. Any fees charged by Service Organizations or other 
institutional investors to their customers in connection with 
investments in Fund shares are not reflected in the Fund's 
expenses. 

YIELDS

	From time to time the "yields" and "effective yields" for 
Class A, Class B and Class C shares may be quoted in 
advertisements or in reports to investors. The "yield" quoted in 
advertisements for a particular class or sub-class 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 class or 
sub-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 Fund's yields may be compared to those of other mutual 
funds with similar objectives, 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 IBC/Donoghue's Money Fund Report, The Wall 
Street Journal and The New York Times, reports prepared by Lipper 
Analytical Service, Inc. and publications of local or regional 
nature. 

	The Fund's yield figures for a Class of shares represents 
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. Since holders of Class B or 
Class C shares bear all service fees for services provided by 
Service Organizations, the net yield on such shares can be 
expected at any given time to be lower than the net yield on 
Class A shares. 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 the Fund's 
expenses or yields. The methods used to compute the Fund's yields 
are described in more detail in the Statement of Additional 
Information. Investors may call 1-800-238-2560 (Class A shares 
code: 003; Class B shares code: 103; Class C shares code: 203) to 
obtain current yield information. 

DESCRIPTION OF SHARES

	

	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 offers thirteen portfolios: Prime Money Market Fund 
(Class A, Class B and Class C), Prime Value Money Market Fund 
(Class A, Class B, Class C and Class D), Government Obligations 
Money Market Fund (Class A, Class B, Class C and Class D), 100% 
Government Obligations Money Market Fund (Class A, Class B and 
Class C), Treasury Instruments Money Market Fund (Class A, Class B 
and Class C), Treasury Instruments Money Market Fund II (Class A, 
Class B and Class C), 100% Treasury Instruments Money Market Fund 
(Class A, Class B and Class C), Tax-Free Money Market Fund 
(Class A, Class B and Class C), Municipal Money Market Fund 
(Class A, Class B, Class C and Class D), California Municipal 
Money Market Fund (Class A, Class B and Class C), New York 
Municipal Money Market Fund (Class A, Class B and Class C), 
Floating Rate U.S. Government Fund (Premier and Select Shares) and 
Short Duration U.S. Government Fund (Premier and Select Shares). 
Shares of the New York Municipal Money Market Fund are not 
currently sold to the public. The Declaration of Trust further 
authorizes the Trustees to classify or reclassify any class of 
shares into one or more sub-classes.

May 31, 1994



	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, 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 that only Class B or Class C shares, as the case 
may be, 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. 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. (See the Statement of Additional Information 
under "Miscellaneous" 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.

possible restrictions on their transferability, see "Purchase and 
Redemption of Shares."

PROSPECTUS

Municipal Money Market Fund

An Investment Portfolio Offered By
Lehman Brothers Institutional Funds Group Trust

	Lehman Brothers Institutional Funds Group Trust (the 
"Trust") is a no-load, open-end, management investment company. 
The shares described in this Prospectus represent interests in the 
Municipal Money Market Fund portfolio (the "Fund"), one of a 
family of portfolios of the Trust. 

	The Fund's investment objective is to provide investors with 
as high a level of current income exempt from federal income tax 
as is consistent with relative stability of principal. The Fund 
invests substantially all of its assets in short-term tax-exempt 
obligations issued by state and local governments and tax-exempt 
derivative securities. All or a portion of the Fund's dividends 
may be a specific preference item for purposes of the federal 
individual and corporate alternative minimum taxes. 

	Fund shares may not be purchased by individuals directly, 
but institutional investors may purchase shares for accounts 
maintained by individuals. The Fund currently offers three classes 
of shares. In addition to Class A shares, institutional investors 
may purchase on behalf of their customers Class B or Class C 
shares which accrue daily dividends in the same manner as Class A 
shares but bear all fees payable by the Fund to institutional 
investors for certain services they provide to the beneficial 
owners of such shares. See "Management of the Fund_Service 
Organizations." 

	Lehman Brothers Inc. ("Lehman Brothers") sponsors the Fund 
and acts as Distributor of its shares. Lehman Brothers Global 
Asset Management Inc. serves as the Fund's Investment Adviser.

	Shares of the Fund are not deposits or obligations of, or 
guaranteed or endorsed by, any bank, and such shares are not 
federally insured by the Federal Deposit Insurance Corporation, 
the Federal Reserve Board or any other government agency. Shares 
of the Fund involve certain investment risks, including the 
possible loss of principal. An investment in the Fund is neither 
insured nor guaranteed by the U.S. government. There can be no 
assurance that it will be able to maintain its net asset value of 
$1.00 per share.

* 	The Expense Summary above has been restated to reflect 
current expected fees and the Fund's Investment Adviser's and 
Administrator's voluntary fee waiver and expense reimbursement 
arrangements in effect for the Fund's fiscal year ending 
January 31, 1995.



	In order to maintain a competitive expense ratio during 
1994, the Fund's Investment Adviser and Administrator have 
voluntarily agreed to waive fees and reimburse expenses if and to 
the extent that total operating expenses (other than taxes, 
interest, brokerage fees and commissions, Rule 12b-1 fees and 
extraordinary expenses) exceed .16% of average daily net assets 
through December 31, 1994. For 1995 and thereafter, the Investment 
Adviser and Administrator intend to continue voluntarily 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. 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 Investment 
Adviser and Administrator total .20% of average daily net assets. 
Absent fee waivers, the Total Fund Operating Expenses of Class A, 
Class B and Class C are expected to be .24%, .49% and .59%, 
respectively, of the Fund's average daily net assets.

INVESTMENT OBJECTIVE AND POLICIES

In General

	The Fund's investment objective is to provide investors with 
as high a level of current income exempt from federal income tax 
as is consistent with relative stability of principal. All or a 
portion of the Fund's dividends may be a specific preference item 
for purposes of the federal individual and corporate alternative 
minimum taxes. 

	In pursuing its investment objective, the Fund, which 
operates as a diversified investment company, invests 
substantially all of its assets in a diversified portfolio 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"). The Fund will not 
knowingly purchase securities the interest on which is subject to 
federal income tax. (See, however, "Taxes" below concerning 
treatment of exempt-interest dividends paid by the Fund for 
purposes of the federal alternative minimum tax applicable to 
particular categories of investors.) 

	Opinions relating to the validity of Municipal Obligations 
and to the exemption of interest thereon from federal income tax 
are rendered by bond counsel to the respective issuers at the time 
of issuance, and opinions relating to the validity of and the 
tax-exempt status of payments received by the Fund from tax-exempt 
derivative securities are rendered by counsel to the respective 
sponsors of such securities. The Fund and its Investment Adviser 
will rely on such opinions and will not review independently the 
underlying proceedings relating to the issuance of Municipal 
Obligations, the creation of any tax-exempt derivative securities 
or the bases for such opinions. 

 Portfolio Quality and Diversification.  The Fund will purchase 
only Municipal Obligations which are "Eligible Securities" (as 
defined by the Securities and Exchange Commission) and which 
present minimal credit risks as determined by the Investment 
Adviser pursuant to guidelines approved by the Trust's Board of 
Trustees. Eligible Securities consist of (i) securities that 
either (a) have short-term debt ratings at the time of purchase 
within the two highest rating categories assigned by at least two 
unaffiliated nationally recognized statistical rating 
organizations ("NRSROs") (or one NRSRO if the security was rated 
by only one NRSRO), or (b) are issued by issuers with such 
ratings, and (ii) certain securities that are unrated (including 
securities of issuers that have long-term but not short-term 
ratings) but are of comparable quality as determined by the 
Investment Adviser pursuant to guidelines approved by the Trust's 
Board of Trustees. The Appendix to the Statement of Additional 
Information includes a description of applicable NRSRO ratings. 

	Except during temporary defensive periods, the Fund will 
invest substantially all, but in no event less than 80%, of its 
total assets in Municipal Obligations with remaining maturities of 
thirteen months or less as determined in accordance with the 
rules of the Securities and Exchange Commission. The Fund 
maintains a dollar-weighted average portfolio maturity of 90 days 
or less. The Fund may hold uninvested cash reserves pending 
investment, 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. 

Investment Limitations

	There can be no assurance that the Fund will achieve its 
investment objective. The investment limitations enumerated below 
and the Fund's policy of investing at least 80% of its total 
assets in Municipal Obligations are fundamental and may not be 
changed by the Trust's Board of Trustees without the affirmative 
vote of the holders of a majority of the Fund's outstanding 
shares. The Fund's investment objective and other investment 
policies described above may be changed by the Board of Trustees 
at any time. If there is a change in the investment objective, 
investors should consider whether the Fund remains an appropriate 
investment in light of their then current financial position and 
needs. (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 Objective 
and Policies.") 

	The Fund may not: 

	1.	Borrow money except from banks for temporary purposes 
and then in amounts not exceeding 10% of the value of the Fund's 
assets; or mortgage, pledge or hypothecate any assets except in 
connection with any such borrowing and in amounts not in excess of 
the lesser of the dollar amounts borrowed or 10% of the value of 
the Fund's total assets at the time of such borrowing. Additional 
investments will not be made 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 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. 

	3.	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, provided that there is no limitation with respect 
to investments in U.S. government securities. 

Types of Municipal Obligations

	The two principal classifications of Municipal Obligations 
which may be held by the Fund 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 are not payable 
from the unrestricted revenues of the issuer. Consequently, the 
credit quality of private activity bonds is usually directly 
related to the credit standing of the corporate user of the 
facility involved. 

	The Tax Reform Act of 1986 substantially revised provisions 
of prior law affecting the issuance and use of proceeds of certain 
tax-exempt obligations. A new definition of private activity bonds 
was applied to many types of bonds, including those which were 
industrial development bonds under prior law. Interest on private 
activity bonds is tax-exempt only if the bonds fall within certain 
defined categories of qualified private activity bonds and meet 
the requirements specified in those respective categories. The Act 
generally did not change the tax treatment of bonds issued to 
finance governmental operations. The changes generally apply to 
bonds issued after August 15, 1986, with certain transitional rule 
exemptions. As used in this Prospectus, the term "private activity 
bonds" also includes industrial development revenue bonds issued 
pursuant to the Internal Revenue Code of 1986, as amended. 

	The Fund's portfolio may also include "moral obligation" 
bonds, which are normally issued by special purpose public 
authorities. If the issuer of moral obligation bonds is unable to 
meet its debt service obligations from current revenues, it may 
draw on a reserve fund, the restoration of which is a moral 
commitment but not a legal obligation of the state or municipality 
which created the issuer. 

Other Investment Practices

	Municipal Obligations purchased by the Fund may include 
variable rate demand notes. Such notes may not be rated by credit 
rating agencies, but unrated notes purchased by the Fund will be 
determined by the Fund's Investment Adviser to be of comparable 
quality at the time of purchase to rated instruments purchasable 
by the Fund. Where necessary to ensure that a note is an Eligible 
Security, the Fund will require that the issuer's obligation to 
pay the principal of the note be backed by a  conditional 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 Fund, the 
Fund may, upon the 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, in 
some instances, make it difficult for the Fund to dispose of a 
variable rate demand note if the issuer were to default on its 
payment obligation or during periods that the Fund is not entitled 
to exercise its demand rights, and the Fund could, for this or 
other reasons, suffer a loss to the extent of the default. While, 
in general, the Fund will invest only in securities that mature 
within thirteen months of purchase, the Fund may invest in 
variable rate demand notes which have nominal maturities in excess 
of thirteen months, if such instruments carry demand features that 
comply with conditions established by the Securities and Exchange 
Commission. 

	The Fund may also purchase Municipal Obligations 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 Fund 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 Fund expects that 
commitments to purchase when-issued securities will not exceed 25% 
of the value of its total assets absent unusual market conditions. 
The Fund does not intend to purchase when-issued securities for 
speculative purposes but only in furtherance of its investment 
objective. 

	In addition, the 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 the 
Fund's option specified Municipal Obligations at a specified 
price. The Fund will acquire stand-by commitments solely to 
facilitate portfolio liquidity and does not intend to exercise its 
rights thereunder for trading purposes. 

	Although the Fund may invest more than 25% of its net assets 
in (i) Municipal Obligations whose issuers are in the same state 
and (ii) 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, are issued by issuers 
located in the same state or are private activity bonds, 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. 

	The Fund 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 Fund's Investment 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 
Fund may purchase tender option bonds with different types of 
ownership, payment, credit, and/or liquidity arrangements. 

	The Fund may acquire custodial receipts or certificates 
underwritten by securities dealers or banks that evidence 
ownership of future interest payments, principal payments or both, 
on certain municipal obligations. The underwriter of these 
certificates or receipts typically purchases municipal obligations 
and deposits the obligations in an irrevocable trust or custodial 
account with a Custodian bank, which then issues receipts or 
certificates that evidence ownership of the periodic unmatured 
coupon payments and the final principal payment on the 
obligations. Although under the terms of a custodial receipt, the 
Fund would be typically authorized to assert its rights directly 
against the issuer of the underlying obligation, the Fund could be 
required to assert through the Custodian bank those rights as may 
exist against the underlying issuer. Thus, in the event the 
underlying issuer fails to pay principal and/or interest when due, 
the Fund may be subject to delays, expenses and risks that are 
greater than those that would have been involved if the Fund had 
purchased a direct obligation of the issuer. In addition, in the 
event that the trust or custodial account in which the underlying 
security has been deposited is determined to be an association 
taxable as a corporation instead of a non-taxable entity, the 
yield on the underlying security would be reduced in recognition 
of any taxes paid. 

	The Fund may purchase from financial institutions tax-exempt 
participation interests in Municipal Obligations. A participation 
interest gives the 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. The 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 Obligation, plus accrued 
interest. The Fund will invest no more than 5% of its total assets 
in participation interests. 

	The Fund will not knowingly invest more than 10% of the 
value of its 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). 
The Fund 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"). The Fund 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 Fund 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 normally is 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 10% limitation on investment in illiquid 
securities. The Fund's Investment Adviser will monitor the 
liquidity of such restricted securities under the supervision of 
the Board of Trustees. See "Investment Objective and 
Policies_Additional Information and Investment Practices_Illiquid 
Securities" in the Statement of Additional Information. 

	The value of the Fund's portfolio securities can be expected 
to vary inversely with changes in prevailing interest rates. 

PURCHASE AND REDEMPTION OF SHARES

Purchase Procedures

	Shares of the Fund 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 by the Fund only on days on which 
both Lehman Brothers 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. Orders received prior to noon, 
Eastern time, for which payment has been received by Boston Safe 
Deposit and Trust Company ("Boston Safe"), the Fund's Custodian, 
will be executed at noon. Orders received prior to noon for which 
payment is received between noon and 4:00 P.M., Eastern time, will 
be executed at 4:00 P.M. Orders received after noon, and orders 
for which payment has not been received by 4:00 P.M., Eastern 
time, will not be accepted and notice thereof will be given to the 
institution placing the order. Payment for Fund shares may be made 
only in federal funds immediately available to Boston Safe. 
(Payment for orders which are not received or accepted by Lehman 
Brothers will be returned after prompt inquiry to the sending 
institution.) The Fund may in its discretion reject any order for 
shares. 

	The minimum aggregate initial investment by an institution 
in the investment portfolios that comprise the Trust is $1 million 
(with not less than $25,000 invested in any one investment 
portfolio offered by the Trust); 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. 

	Conflict of interest restrictions may apply to an 
institution's receipt of compensation paid by the Fund in 
connection with the investment of fiduciary funds in Class B or 
Class C shares. See also "Management of the Fund_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 Securities and 
Exchange Commission, the Department of Labor or state securities 
commissions, are urged to consult their legal advisers before 
investing fiduciary funds in Class B or Class C shares. 

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

	Redemption orders must be transmitted to Lehman Brothers by 
telephone at 1-800-851-3134. Payment for redeemed shares for which 
a redemption order is received by Lehman Brothers before noon, 
Eastern time, on a day that both Lehman Brothers and the Federal 
Reserve Bank of Boston are open for business is normally made in 
federal funds wired to the redeeming investor on the same business 
day. Payment for redeemed shares for which a redemption order is 
received by Lehman Brothers after noon, Eastern time, on such a 
business day is normally made in federal funds wired to the 
redeeming investor on the next business day following redemption. 

	Shares are redeemed at the net asset value per share next 
determined after Lehman Brothers' receipt of the redemption order. 
While the Fund intends to use its best efforts to maintain its 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. To allow the Fund's Investment Adviser to manage the 
Fund 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. 

	The Fund reserves the right to wire redemption proceeds 
within seven days after receiving the redemption order if, in the 
judgment of the Investment Adviser, an earlier payment could 
adversely affect the Fund. The Fund shall have the right to redeem 
shares involuntarily in any account at its 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 Fund 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." 

Valuation of Shares_Net Asset Value

	The Fund's net asset value per share for purposes of pricing 
purchase and redemption orders is determined by the Fund's 
Administrator as of noon and 4:00 P.M., Eastern time, on each 
weekday, with the exception of those holidays on which either 
Lehman Brothers or the Federal Reserve Bank of Boston is closed. 
Currently, one or both of these institutions 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 the Fund 
is calculated by adding the value of all securities and other 
assets of the Fund, subtracting liabilities and dividing the 
result by the total number of the Fund's outstanding shares 
(irrespective of class or sub-class). In computing net asset 
value, the Fund uses the amortized cost method of valuation as 
described in the Statement of Additional Information under 
"Additional Purchase and Redemption Information." The Fund's net 
asset value per share for purposes of pricing purchase and 
redemption orders is determined independently of the net asset 
value of the Trust's other investment portfolios. 

Other Matters

	Fund shares are sold and redeemed without charge by the 
Fund. Institutional investors purchasing or holding Fund shares 
for their customers' 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 the Fund are entitled to dividends and 
distributions arising only from the net investment income and 
capital gains, if any, earned on its investments held by the Fund. 
The Fund's net investment income is declared daily as a dividend 
to shareholders of record at the close of business on the day of 
declaration. As a result, at any given time, the net yield on 
Class B and Class C shares will be .25% and .35%, respectively, 
lower than the net yield on Class A shares. Shares begin accruing 
dividends on the day the purchase order for the shares is effected 
and continue to accrue dividends through the day 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 Fund does 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 share of the Fund 
irrespective of class, except that Class B or Class C shares bear 
all the expense of fees paid to Service Organizations. 

	Institutional investors may elect to have their dividends 
reinvested in additional full and fractional shares of the same 
class 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 the Fund's Distributor, at 260 Franklin Street, 
15th Floor, Boston, Massachusetts 02110-9624, and will become 
effective after its receipt by the Distributor with respect to 
dividends paid. 

	The Shareholder Services Group, Inc. ("TSSG"), 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

	The Fund qualified in its last taxable year and intends to 
qualify in future years as a "regulated investment company" under 
the Internal Revenue Code of 1986, as amended (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 the 
Fund distribute to its investors at least 90% of its 
exempt-interest income net of certain deductions and 90% of its 
investment company taxable income for such year. Dividends derived 
from exempt-interest income 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. (See the Statement of Additional Information under 
"Additional Information Concerning Taxes.") 

	The 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 their federal 
alternative minimum taxable income for purposes of determining 
liability (if any) for the 24% alternative minimum tax applicable 
to individuals and the 20% alternative minimum tax and the 
environmental tax applicable to corporations. 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 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. Under state or local law, the Fund's distributions of net 
investment income may be taxable to investors as dividend income 
even though a substantial portion of such distributions may be 
derived from interest on tax-exempt obligations which, if realized 
directly, would be exempt from such income taxes. 

	Dividends declared in October, November or December of any 
year payable to shareholders of record on a specified date in such 
months will be deemed to have been received by the investors and 
paid by the Fund on December 31 of such year in the event such 
dividends are actually paid during January of the following year. 

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

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

MANAGEMENT OF THE FUND

	The business and affairs of the Fund 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 Fund, including agreements 
with its Distributor, Investment Adviser, Administrator, Custodian 
and Transfer Agent. The day- to-day operations of the Fund are 
delegated to the Fund's Investment Adviser and Administrator. The 
Statement of Additional Information relating to the Fund 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 the Fund's shares. 
Lehman Brothers is a wholly-owned subsidiary of Lehman Brothers 
Holdings Inc. ("Holdings"). Prior to May 31, 1994, all of the 
issued and outstanding common stock (representing 92% of the 
voting stock) of Holdings was held by American Express Company. On 
May 31, 1994, American Express distributed to holders of common 
stock of American Express all outstanding shares of common stock 
of Holdings. As of May 31, 1994, Nippon Life Insurance Company 
owned 11.2% 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 Fund. 

Investment Adviser_Lehman Brothers Global Asset Management Inc.

	Lehman Brothers Global Asset Management Inc. ("LBGAM"), 
located at 3 World Financial Center, New York, New York 10285, 
serves as the Fund's Investment Adviser. LBGAM is a wholly owned 
subsidiary of Holdings. LBGAM, together with other Lehman Brothers 
investment advisory affiliates, serves as Investment Advisor to 
investment companies private accounts and has assets under 
management of approximately $15 billion as of March 31, 1994. 

	As Investment Adviser to the Fund, LBGAM will among other 
things, participate in the formulation of the Fund's investment 
policies, analyze economic trends affecting the Fund and monitor 
and evaluate the Fund's investment objective and policies and the 
Fund's investment performance. For its services LBGAM is entitled 
to receive a monthly fee from the Fund at the annual rate of .10% 
of the value of the Fund's average daily net assets. For the 
period February 8, 1993 (commencement of operations) to 
January 31, 1994, LBGAM received no advisory fees from the Fund. 

Administrator and Transfer Agent_The Shareholder Services Group, 
Inc.

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

Custodian_Boston Safe Deposit and Trust Company

	Boston Safe, a wholly owned subsidiary of The Boston 
Company, Inc., located at One Boston Place, Boston, Massachusetts 
02108, serves as the Fund's Custodian. 

Service Organizations

	Financial institutions such as banks, savings and loan 
associations and other such institutions ("Service Organizations") 
and/or institutional customers of Service Organizations may 
purchase Class B or Class C shares. These shares are identical in 
all respects to Class A shares except that they bear the fees 
described below and enjoy certain exclusive voting rights on 
matters relating to these fees. The Fund will enter into an 
agreement with each Service Organization whose customers 
("Customers") are the beneficial owners of Class B or Class C 
shares that requires the Service Organization to provide certain 
services to Customers in consideration of the Fund's payment of 
service fees at the annual rate of .25% or .35%, respectively, of 
the average daily net asset value of the respective Class 
beneficially owned by the Customers. Such services, which are 
described more fully in the Statement of Additional Information 
under "Management of the Fund_Service Organizations," may include 
aggregating and processing purchase and redemption requests from 
Customers and placing net purchase and redemption orders with 
Lehman Brothers; processing dividend payments from the Fund on 
behalf of Customers; providing information periodically to 
Customers showing their positions in shares; arranging for bank 
wires; responding to Customer inquiries relating to the services 
provided by the Service Organization and handling correspondence; 
acting as investor of record and nominee; and providing reasonable 
assistance in connection with the distribution of shares to 
Customers. Services provided with respect to Class B shares will 
generally be more limited than those provided with respect to 
Class C Shares. Under the terms of the agreements, Service 
Organizations are required to provide to their Customers a 
schedule of any fees that they may charge Customers in connection 
with their investments in Class B or Class C shares. Class A 
shares are sold to financial institutions that have not entered 
into servicing agreements with the Fund in connection with their 
investments. A salesperson and any other person entitled to 
receive compensation for selling or servicing shares of the Fund 
may receive different compensation for selling or servicing one 
Class of shares over another Class. 

Expenses

	The Fund bears all of its own expenses. The 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, Securities and Exchange Commission 
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, 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. The 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 during 1994; LBGAM and TSSG have agreed 
voluntarily to reimburse the Fund if and to the extent that the 
Fund's total operating expenses (other than taxes, interest, 
brokerage fees and commissions, Rule 12b-1 fees under the 1940 Act 
and extraordinary expenses) exceed .16% of average daily net 
assets through December 31, 1994. The Investment Adviser and 
Administrator intend to continue voluntarily to waive fees to the 
extent necessary to maintain an annualized expense ratio at a 
level no greater than .18% of average daily net assets thereafter. 
This voluntary reimbursement will not be changed unless investors 
are provided at least 60 days' advance notice. In addition, these 
service providers have agreed to reimburse the Fund to the extent 
required by applicable state law for certain expenses that are 
described in the Statement of Additional Information relating to 
the Fund. Any fees charged by Service Organizations or other 
institutional investors to their customers in connection with 
investments in Fund shares are not reflected in the Fund's 
expenses. 

YIELDS

	From time to time, the "yields," and "effective yields" for 
Class A, Class B or Class C shares may be quoted in advertisements 
or in reports to investors. Yield quotations are computed 
separately for each Class of shares. The "yield" quoted in 
advertisements for each a particular class or sub-class of shares 
refers to the income generated by an investment in such shares of 
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 or sub-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 the Fund's 
tax-free yield for each class or sub-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." 

	The Fund's yields 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 IBC/Donoghue's Money Fund Report, Ibbotson 
Associates of Chicago, The Wall Street Journal and The New York 
Times, reports prepared by Lipper Analytical Services, Inc. and 
publications of a local or regional nature. 

	The 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. Since holders of Class B and 
Class C shares bear the service fees for services provided by 
Service Organizations, the net yield on such shares can be 
expected at any given time to be lower than the net yield on 
Class A shares. 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 the Fund's 
expenses or yields. The methods used to compute the Fund's yields 
are described in more detail in the Statement of Additional 
Information. Investors may call 1-800-238-2560 (Class A shares 
code: 009; Class B shares code: 109; Class C shares code: 209) to 
obtain current yield information. 

DESCRIPTION OF SHARES

	The Trust was organized as a Massachusetts business trust 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 classes of shares. 
The Trust is an open-end management investment company, which 
offers thirteen portfolios; Prime Money Market Fund (Class A, 
Class B and Class C), Prime Value Money Market Fund (Class A, 
Class B, Class C and Class D), Government Obligations Money Market 
Fund (Class A, Class B, Class C and Class D), 100% Government 
Obligations Money Market Fund (Class A, Class B and Class C), 
Treasury Instruments Money Market Fund (Class A, Class B and 
Class C), Treasury Instruments Money Market Fund II (Class A, 
Class B and Class C), 100% Treasury Instruments Money Market Fund 
(Class A, Class B and Class C), Tax-Free Money Market Fund 
(Class A, Class B and Class C), Municipal Money Market Fund 
(Class A, Class B, Class C and Class D), California Municipal 
Money Market Fund (Class A, Class B and Class C), New York 
Municipal Money Market Fund (Class A, Class B and Class C), 
Floating Rate U.S. Government Fund (Preimer and Select Shares) and 
Short Duration U.S. Government Fund (Preimer and Select Shares.) 
Shares of the New York Municipal Money Market Fund are not 
currently sold to the public. 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 investors except as required by the 1940 Act or other 
applicable law. The Trust will call a meeting of investors for the 
purpose of voting upon the question of removal of a member of the 
Board of Trustees upon written request of investors 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, 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 that only Class B or Class C shares, as the case 
may be, will be entitled to vote on matters submitted to a vote of 
investors pertaining to the Fund's arrangements with Service 
Organizations with respect to the relevant Class. Further, 
investors of all of the Fund and 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 
investors 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."

expected fees and the Fund's Investment Adviser's and 
Administrator's 
voluntary fee waiver and expense reimbursement arrangements in 
effect for 
the Fund's fiscal year ending January 31, 1995.




	In order to maintain a competitive expense ratio during 
1994, the Funds' Investment Adviser and Administrator have 
voluntarily agreed to waive fees and reimburse expenses if and to 
the extent that total operating expenses (other than taxes, 
interest, brokerage fees and commissions, Rule 12b-1 fees and 
extraordinary expenses) exceed .16% of average daily net assets 
through December 31, 1994. For 1995 and thereafter, the Investment 
Adviser and Administrator intend to continue voluntarily 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. The voluntary fee waiver and fee 
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 Investment 
Adviser and Administrator total .20% of average daily net assets. 
Absent fee waivers, the Total Fund Operating Expenses of Class A, 
Class B and Class C are expected to be .24%, .49% and .59%, 
respectively, of the Fund's average daily net assets.

INVESTMENT OBJECTIVE AND POLICIES

In General

	The Fund's investment objective is to provide current income 
and stability of principal. In pursuing its investment objective, 
the Fund, which operates as a diversified investment portfolio, 
invests 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. 

 Price and Portfolio Maturity.  The Fund invests only in 
securities that are purchased with and payable in U.S. dollars and 
that have (or, pursuant to regulations adopted by the Securities 
and Exchange Commission, will be deemed to have) remaining 
maturities of thirteen months or less at the date of purchase by 
the Fund. The Fund maintains a dollar-weighted average portfolio 
maturity of 90 days or less. The Fund follows these policies to 
maintain a constant net asset value of $1.00 per share, although 
there is no assurance that it can do so on a continuing basis. 

 Portfolio Quality and Diversification.  The Fund will limit its 
portfolio investments to securities that the Trust's 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 ratings 
with respect to other short-term debt securities and comparable 
unrated securities. "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 
Corporation, Moody's Investors Service, Inc., 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. The 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.

	The following descriptions illustrate the kinds of 
instruments in which the Fund invests: 

	The Fund may purchase U.S. bank and bank holding company 
obligations such as commercial paper, notes, certificates of 
deposit, bankers' acceptances and time deposits, including 
instruments issued or supported by the credit of domestic banks or 
savings institutions having total assets at the time of purchase 
in excess of $1 billion. The Fund may also make interest- bearing 
savings deposits in commercial and savings banks in amounts not in 
excess of 5% of the Fund's assets. 

	The Fund may invest in commercial paper and other short-term 
obligations. The Fund may not invest in commercial paper or 
obligations of foreign issuers. 

	The Fund may purchase variable or floating rate notes, which 
are unsecured instruments that provide for adjustments in the 
interest rate on certain reset dates or whenever a specified 
interest rate index changes, respectively. Such notes may not be 
actively traded in a secondary market, but, in some cases, the 
Fund may be able to resell such notes in the dealer market. 
Variable and floating notes typically are rated by credit rating 
agencies, and their issuers must satisfy the same quality criteria 
as set forth above. The Fund invests in variable or floating rate 
notes only when the Investment Adviser deems the investment to 
involve minimal credit risk. 

	The Fund may purchase instruments from financial 
institutions, such as banks and broker- dealers, subject to the 
seller's agreement to repurchase them at an agreed upon time and 
price ("repurchase agreements"). 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. 
Default by the seller would, however, expose the Fund to possible 
loss because of adverse market action or delay in connection with 
the disposition of the underlying obligations. 
	The Fund may also 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 Fund 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 Fund expects that commitments to 
purchase when-issued securities will not exceed 25% of the value 
of its total assets absent unusual market conditions. The Fund 
does not intend to purchase when-issued securities for speculative 
purposes but only in furtherance of its investment objective. 

	The Fund may purchase obligations issued or guaranteed by 
the U.S. government or its agencies and instrumentalities. 
Obligations of certain agencies and instrumentalities of the U.S. 
government are backed by the full faith and credit of the United 
States. Others are backed by the right of the issuer to borrow 
from the U.S. Treasury or are backed only by the credit of the 
agency or instrumentality issuing the obligation. 

	In addition, the Fund may, when deemed appropriate in light 
of the Fund's investment objective, invest in high quality, 
short-term obligations issued by the state and local governmental 
issuers which carry yields that are competitive with those of 
other types of money market instruments of comparable quality. 

	The Fund will not knowingly invest more than 10% of the 
value of its total 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). 
The Fund 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"). The Fund 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 Fund 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 normally is 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 10% limitation on investment in illiquid 
securities. 

	There can be no assurance that the Fund will achieve its 
investment objective. 

Investment Limitations

	The Fund's investment objective and the policies described 
above are not fundamental and may be changed by the Trust's Board 
of Trustees without a vote of shareholders. If there is a change 
in the investment objective, investors should consider whether the 
Fund remains an appropriate investment in light of their then 
current financial position and needs. The Fund's investment 
limitations summarized below may not be changed without the 
affirmative vote of the holders of a majority of its outstanding 
shares. (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 Objective 
and Policies.")

The Fund may not: 1.Borrow money, except from banks for temporary 
purposes and then in amounts not in excess of 10% of the value of 
the Fund's assets at the time of such borrowing; or pledge any 
assets except in connection with any such borrowing and in amounts 
not in excess of the lesser of the dollar amounts borrowed or 10% 
of the value of the Fund's assets at the time of such borrowing. 
Additional investments will not be made 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 
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 obligations and obligations of domestic banks. 

PURCHASE AND REDEMPTION OF SHARES

Purchase Procedures

	Shares of the Fund 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 Lehman 
Brothers 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. Orders received prior to noon, Eastern time, 
for which payment has been received by Boston Safe Deposit and 
Trust Company ("Boston Safe"), the Fund's Custodian, will be 
executed at noon. Orders received between noon and 3:00 P.M., 
Eastern time, will be executed at 3:00 P.M., Eastern time, if 
payment has been received by Boston Safe by 3:00 P.M. and will be 
executed at 4:00 P.M. if payment has been received by 4:00 P.M. 
Orders received after 3:00 P.M., and orders for which payment has 
not been received by 4:00 P.M., Eastern time, will not be 
accepted, and notice thereof will be given to the institution 
placing the order. Payment for Fund shares may be made only in 
federal funds immediately available to Boston Safe. (Payment for 
orders which are not received or accepted by Lehman Brothers will 
be returned after prompt inquiry to the sending institution.) The 
Fund may in its discretion reject any order for shares. 

	The minimum aggregate initial investment by an institution 
in the investment portfolios that comprise the Trust is $1 million 
(with not less than $25,000 invested in any one investment 
portfolio offered by the Trust); 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. 

	Conflict of interest restrictions may apply to an 
institution's receipt of compensation paid by the Fund on 
fiduciary funds that are invested in Class B or Class C shares. 
See also "Management of the Fund_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 Securities and Exchange Commission, the 
Department of Labor or state securities commissions, are urged to 
consult their legal advisers before investing fiduciary funds in 
Class B or Class C shares. 

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

Redemption Procedures

	Redemption orders must be transmitted to Lehman Brothers by 
telephone at 1-800-851-3134. Payment for redeemed shares for which 
a redemption order is received by Lehman Brothers before 
3:00 P.M., Eastern time, on a day that both Lehman Brothers and 
the Federal Reserve Bank of Boston are open for business is 
normally made in federal funds wired to the redeeming shareholder 
on the same business day. Payment for redemption orders which are 
received between 3:00 P.M. and 4:00 P.M., Eastern time, is 
normally wired in federal funds on the next business day following 
redemption. 

	Shares are redeemed at the net asset value per share next 
determined after Lehman Brothers' receipt of the redemption order. 
While the Fund intends to use its best efforts to maintain its 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. To allow the Fund's Investment Adviser to manage the 
Fund 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. 

	The Fund reserves the right to wire redemption proceeds 
within seven days after receiving the redemption order if, in the 
judgment of the Investment Adviser, an earlier payment could 
adversely affect the Fund. The Fund 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 Fund 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." 

Valuation of Shares_Net Asset Value

	The Fund's net asset value per share for purposes of pricing 
purchase and redemption orders is determined by the Fund's 
Administrator as of noon, 3:00 P.M. and 4:00 P.M., Eastern time, 
on each weekday, with the exception of those holidays on which 
either Lehman Brothers or the Federal Reserve Bank of Boston is 
closed. Currently, one or both of these institutions 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 by adding the value of all securities and 
other assets of the Fund, subtracting liabilities, and dividing 
the result by the total number of the Fund's outstanding shares 
(irrespective of class or sub-class). In computing net asset 
value, the Fund uses the amortized cost method of valuation as 
described in the Statement of Additional Information under 
"Additional Purchase and Redemption Information." The 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 the Trust's other investment portfolios. 

Other Matters

	Fund shares are sold and redeemed without charge by the 
Fund. 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 the Fund are entitled to dividends and 
distributions arising only from the net investment income and 
capital gains, if any, earned on investments held by the Fund. The 
Fund's net investment income is declared daily as a dividend to 
shares held of record at the close of business on the day of 
declaration. Shares begin accruing dividends on the day the 
purchase order for the shares is executed and continue to accrue 
dividends through, and including, the day before the redemption 
order for the shares is executed. 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 Fund does 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 Class B and 
Class C shares bear all the expense of fees paid to Service 
Organizations. As a result, at any given time, the net yield on 
Class B and Class C shares will be .25% and .35%, respectively, 
lower than the net yield on Class A shares. 

	Institutional shareholders 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 the Fund's Distributor, at 260 Franklin Street, 
15th Floor, Boston, Massachusetts 02110-9624, and will become 
effective after its receipt by the Distributor, with respect to 
dividends paid. 

	The Shareholder Services Group, Inc. ("TSSG"), 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

	

	The Fund qualified in its last taxable year and intends to 
qualify in future years as a "regulated investment company" under 
the Internal Revenue Code of 1986, as amended (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 the 
Fund distribute to its investors at least 90% of its investment 
company taxable income for such year. In general, the 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 gain for the taxable year over the net 
short-term capital loss, if any, for such year. The 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 
the Fund's distributions will be eligible for the dividends 
received deduction for corporations. The Fund does not expect to 
realize long-term capital gains and, therefore, does not 
contemplate payment of any "capital gain dividends" as described 
in the Code. 

	Dividends declared in October, November or December of any 
year payable to investors of record on a specified date in such 
months will be deemed to have been received by the investors and 
paid by the Fund on December 31 of such year in the event such 
dividends are actually paid during January of the following year. 

	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 the 
Fund and its investors. No attempt is made to present a detailed 
explanation of the federal, state or local income tax treatment of 
the Fund or its investors, and this discussion is not intended as 
a substitute for careful tax planning. Accordingly, potential 
investors in the Fund should consult their tax advisers with 
specific reference to their own tax situation. 

MANAGEMENT OF THE FUND

	The business and affairs of the Fund 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 Fund, including agreements 
with its Distributor, Investment Adviser, Administrator, Custodian 
and Transfer Agent. The day-to-day operations of the Fund are 
delegated to the Fund's Investment Adviser and Administrator. The 
Statement of Additional Information relating to the Fund 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 the Fund's shares. 
Lehman Brothers is a wholly-owned subsidiary of Lehman Brothers 
Holdings Inc. ("Holdings"). Prior to May 31, 1994, all of the 
issued and outstanding common stock (representing 92% of the 
voting stock) of Holdings was held by American Express Company. On 
May 31, 1994, American Express distributed to holders of common 
stock of American Express all outstanding shares of common stock 
of Holdings. As of May 31, 1994, Nippon Life Insurance Company 
owned 11.2% 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 Fund. 

Investment Adviser_Lehman Brothers Global Asset Management Inc.

	Lehman Brothers Global Asset Management Inc. ("LBGAM"), 
located at 3 World Financial Center, New York, New York 10285, 
serves as the Fund's Investment Adviser. LBGAM is a wholly owned 
subsidiary of Holdings. LBGAM, together with the other Lehman 
Brothers investment advisory affiliates serves as Investment 
Adviser to investment companies and private accounts and has 
assets under management of approximately $15 billion as of March 
31, 1994. 

	As Investment Adviser to the Fund, LBGAM will among other 
things, participate in the formulation of the Fund's investment 
policies, analyze economic trends affecting the Fund and monitor 
and evaluate the Fund's investment objective and policies and the 
Fund's investment performance. For its services LBGAM is entitled 
to receive a monthly fee from the Fund at the annual rate of .10% 
of the value of the Fund's average daily net assets. For the 
period February 8, 1993 (commencement of operations) to 
January 31, 1994, LBGAM received no advisory fees from the Fund.

Administrator and Transfer Agent_The Shareholder Services 
Group, Inc.

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

	Boston Safe, a wholly owned subsidiary of The Boston 
Company, Inc., located at One Boston Place, Boston, Massachusetts 
02108, serves as the Fund's Custodian. 

Service Organizations

	Financial institutions, such as banks, savings and loan 
associations and other such institutions ("Service Organizations") 
and/or institutional customers of Service Organizations may 
purchase Class B or Class C shares. These shares are identical in 
all respects to Class A shares except that they bear the fees 
described below and enjoy certain exclusive voting rights on 
matters relating to these fees. The Fund will enter into an 
agreement with each Service Organization whose customers 
("Customers") are the beneficial owners of Class B or Class C 
shares that requires the Service Organization to provide certain 
services to Customers in consideration of the Fund's payment of 
service fees at the annual rate of .25% or .35%, respectively, of 
the average daily net asset value of the respective Class 
beneficially owned by Customers. Such services, which are 
described more fully in the Statement of Additional Information 
under "Management of the Fund_Service Organizations," may include 
aggregating and processing purchase and redemption requests from 
Customers and placing net purchase and redemption orders with 
Lehman Brothers; processing dividend payments from the Fund on 
behalf of Customers; providing information periodically to 
Customers showing their positions in shares; arranging for bank 
wires; responding to Customer inquiries relating to the services 
provided by the Service Organization and handling correspondence; 
acting as shareholder of record and nominee; and providing 
reasonable assistance in connection with the distribution of 
shares to Customers. Services provided with respect to Class B 
shares will generally be more limited than those provided with 
respect to Class C shares. Under the terms of the agreements, 
Service Organizations are required to provide to their Customers a 
schedule of any fees that they may charge Customers in connection 
with their investments in Class B or Class C shares. Class A 
shares are sold to financial institutions that have not entered 
into servicing agreements with the Fund in connection with their 
investments. A salesperson and any other person entitled to 
receive compensation for selling or servicing shares of the Fund 
may receive different compensation for selling or servicing one 
Class of shares over another Class. 

Expenses

	The Fund bears all its own expenses. The 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, Securities and Exchange Commission 
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, 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. The 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 during 1994, LBGAM and TSSG have agreed 
voluntarily to  reimburse the Fund if and to the extent that the 
Fund's total operating expenses (other than taxes, interest, 
brokerage fees and commissions, Rule 12b-1 fees under the 1940 Act 
and extraordinary expenses) exceed .16% of average daily net 
assets through December 31, 1994. The Investment Adviser and 
Administrator intend to continue voluntarily to waive fees to the 
extent necessary to maintain an annualized expense ratio at a 
level no greater than .18% of average daily net assets thereafter. 
This voluntary reimbursement will not be changed unless investors 
are provided at least 60 days' advance notice. In addition, these 
service providers have agreed to reimburse the Fund to the extent 
required by applicable state law for certain expenses that are 
described in the Statement of Additional Information relating to 
the Fund. Any fees charged by Service Organizations or other 
institutional investors to their customers in connection with 
investments in Fund shares are not reflected in the Fund's 
expenses. 
May 31, 1994



YIELDS From time to time the "yields" and "effective yields" for 
Class A, Class B and Class C shares may be quoted in 
advertisements or in reports to investors. Yield quotations are 
computed separately for each Class of shares. The "yield" quoted 
in advertisements for a particular class or sub-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 or sub-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 Fund's yields 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 IBC/Donoghue's Money Fund Report, The Wall 
Street Journal and The New York Times, reports prepared by Lipper 
Analytical Service, Inc. and publications of a local or regional 
nature. 

	The 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. Since holders of Class B or 
Class C shares bear the service fees for services provided by 
Service Organizations, the net yield on such shares can be 
expected at any given time to be lower than the net yield on 
Class A shares. 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 the Fund's 
expenses or yields. The methods used to compute the Fund's yields 
are described in more detail in the Statement of Additional 
Information. Investors may call 1-800-238-2560 (Class A shares 
code: 001; Class B shares code: 101; Class C shares code: 201) to 
obtain current yield information. 

DESCRIPTION OF SHARES 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 offers thirteen portfolios: Prime Money Market Fund 
(Class A, Class B and Class C), Prime Value Money Market Fund 
(Class A, Class B, Class C and Class D), Government Obligations 
Money Market Fund (Class A, Class B, Class C and Class D), 100% 
Government Obligations Money Market Fund (Class A, Class B and 
Class C), Treasury Instruments Money Market Fund (Class A, Class B 
and Class C), Treasury Instruments Money Market Fund II (Class A, 
Class B and Class C), 100% Treasury Instruments Money Market Fund 
(Class A, Class B and Class C), Tax-Free Money Market Fund 
(Class A, Class B and Class C), Municipal Money Market Fund 
(Class A, Class B, Class C and Class D), California Municipal 
Money Market Fund (Class A, Class B and Class C), New York 
Municipal Money Market Fund (Class A, Class B and Class C), 
Floating Rate U.S. Government Fund (Premier and Select Shares) and 
Short Duration U.S. Government Fund (Premier and Select Shares). 
Shares of the New York Municipal Money Market Fund are not 
currently sold to the public. 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 that only Class B or Class C shares, as the case 
may be, 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. Further, 
shareholders of the Fund and of the Trust's other 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. (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 Expense Summary above has been restated to reflect 
current expected fees and the Fund's Investment Adviser's and 
Administrator's voluntary fee waiver and expense reimbursement 
arrangements in effect for the Fund's fiscal year ending 
January 31, 1995. 

	In order to maintain a competitive expense ratio during 
1994, the Fund's Investment Adviser and Administrator have 
voluntarily agreed to waive fees and reimburse expenses if and to 
the extent that total operating expenses (other than taxes, 
interest, brokerage fees and commissions, Rule 12b-1 fees and 
extraordinary expenses) exceed .16% of average daily net assets 
through December 31, 1994. For 1995 and thereafter, the Investment 
Adviser and Administrator intend to continue voluntarily 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. 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 Investment 
Adviser and Administrator total .20% of average daily net assets. 
Absent fee waivers, the Total Fund Operating Expenses of Class A, 
Class B and Class C are expected to be .24%, .49% and .59%, 
respectively, of the Fund's average daily net assets.

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 following shares:

INVESTMENT OBJECTIVE AND POLICIES

In General

	The Fund's investment objective is to provide current income 
and stability of principal. In pursuing its investment objective, 
the Fund, which operates as a diversified investment portfolio, 
invests in a broad range of short-term instruments, including U.S. 
government and U.S. and foreign bank and commercial obligations 
and repurchase agreements relating to such obligations. 

 Price and Portfolio Maturity.  The Fund invests only in 
securities that are purchased with and payable in U.S. dollars and 
that have (or, pursuant to regulations adopted by the Securities 
and Exchange Commission, will be deemed to have) remaining 
maturities of thirteen months or less at the date of purchase by 
the Fund. The Fund maintains a dollar-weighted average portfolio 
maturity of 90 days or less. The Fund follows these policies to 
maintain a constant net asset value of $1.00 per share, although 
there is no assurance that it can do so on a continuing basis. 

 Portfolio Quality and Diversification.  The Fund will limit its 
portfolio investments to securities that the Trust's 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. "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 
Corporation, Moody's Investors Service, Inc., 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. 

	The 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, the 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 asset in the Second Tier 
Securities of any one issuer. The Fund 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. 

	The following descriptions illustrate the kinds of 
instruments in which the Fund invests: 

	The 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 banks or savings institutions having total 
assets at the time of purchase in excess of $1 billion. The Fund 
may also make interest-bearing savings deposits in commercial and 
savings banks in amounts not in excess of 5% of its assets. 

	The Fund may invest in commercial paper and other short-term 
obligations. The Fund may invest without limit in commercial paper 
and obligations of foreign issuers. 

	The 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 Investment Adviser deem 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. 

	The Fund may purchase variable or floating rate notes, which 
are unsecured instruments that provide for adjustments in the 
interest rate on certain reset dates or whenever a specified 
interest rate index changes, respectively. Such notes may not be 
actively traded in a secondary market but, in some cases, the Fund 
may be able to resell such notes in the dealer market. Variable 
and floating rate notes typically are rated by credit rating 
agencies, and their issuers must satisfy the same quality criteria 
as set forth above. The Fund invests in variable or floating rate 
notes only when the Investment Adviser deems the investment to 
involve minimal credit risk. 

	The Fund may purchase instruments from financial 
institutions, such as banks and broker-dealers, subject to the 
seller's agreement to repurchase them at an agreed upon time and 
price ("repurchase agreements"). The seller under a repurchase 
agreement will be required to maintain the value of the securities 
subject to the agreement at an amount not less than the repurchase 
price. Default by the seller would, however, expose the Fund to 
possible loss because of adverse market action or delay in 
connection with the disposition of the underlying obligations. 

	The Fund may also 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 Fund 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 Fund expects that commitments to 
purchase when-issued securities will not exceed 25% of the value 
of its total assets absent unusual market conditions. The Fund 
does not intend to purchase when-issued securities for speculative 
purposes but only in furtherance of its investment objective. 

	The Fund may purchase obligations issued or guaranteed by 
the U.S. government or its agencies and instrumentalities. 
Obligations of certain agencies and instrumentalities of the U.S. 
government are backed by the full faith and credit of the United 
States. Others are backed by the right of the issuer to borrow 
from the U.S. Treasury or are backed only by the credit of the 
agency or instrumentality issuing the obligation. 

	In addition, the Fund may, when deemed appropriate in light 
of the Fund's investment objective, invest in high quality, 
short-term obligations issued by state and local governmental 
issuers which carry yields that are competitive with those of 
other types of money market instruments of comparable quality. 

	The Fund will not knowingly invest more than 10% of the 
value of its total 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). 
The Fund 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"). The Fund 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 Fund 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 normally is 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 10% limitation on investment in illiquid 
securities. 

	There can be no assurance that the Fund will achieve its 
investment objective. 

Investment Limitations

	

	The Fund's investment objective and the policies described 
above are not fundamental and may be changed by the Trust's Board 
of Trustees without a vote of shareholders. If there is a change 
in the investment objective, investors should consider whether the 
Fund remains an appropriate investment in light of their then 
current financial position and needs. The Fund's investment 
limitations summarized below may not be changed without the 
affirmative vote of the holders of a majority of its outstanding 
shares. (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 Objective 
and Policies.")

The Fund may not: 

	1.	Borrow money, except from banks for temporary purposes 
and then in amounts not in excess of 10% of the value of the 
Fund's assets at the time of such borrowing; or pledge any assets 
except in connection with any such borrowing and in amounts not in 
excess of the lesser of the dollar amounts borrowed or 10% of the 
value of the Fund's assets at the time of such borrowing. 
Additional investments will not be made when borrowings exceed 5% 
of the Fund's assets. 

	2.	Purchase any securities which would cause, at the time 
of purchase, less than 25% of the value of its total assets to be 
invested in obligations of issuers in the banking industry or in 
obligations, such as repurchase agreements, secured by such bank 
obligations (unless the Fund is in a temporary defensive position) 
or which would cause, at the time of purchase, 75% or more of the 
value of its total assets to be invested in the obligations of 
issuers in any other industry, provided that there is no 
limitation with respect to investments in U.S. government 
obligations. 

PURCHASE AND REDEMPTION OF SHARES

Purchase Procedures

	

	Shares of the Fund 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 Lehman 
Brothers 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. Orders received prior to noon, Eastern time, 
for which payment has been received by Boston Safe Deposit and 
Trust Company ("Boston Safe"), the Fund's Custodian,  will be 
executed at noon. Orders received between noon and 3:00 P.M., 
Eastern time, will be executed at 3:00 P.M., Eastern time, if 
payment has been received by Boston Safe by 3:00 P.M. and will be 
executed at 4:00 P.M., if payment has been received by 4:00 P.M. 
Orders received after 3:00 P.M., and orders for which payment has 
not been received by 4:00 P.M., Eastern time, will not be 
accepted, and notice thereof will be given to the institution 
placing the order. Payment for Fund shares may be made only in 
federal funds immediately available to Boston Safe. (Payment for 
orders which are not received or accepted by Lehman Brothers will 
be returned after prompt inquiry to the sending institution.) The 
Fund may in its discretion reject any order for shares. 

	The minimum aggregate initial investment by an institution 
in the investment portfolios that comprise the Trust is $1 million 
(with not less than $25,000 invested in any one investment 
portfolio offered by the Trust); 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. 

	Conflict of interest restrictions may apply to an 
institution's receipt of compensation paid by the Fund in 
connection with the investment of fiduciary funds in Class B or 
Class C shares. See also "Management of the Fund_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 Securities and 
Exchange Commission, the Department of Labor or state securities 
commissions, are urged to consult their legal advisers before 
investing fiduciary funds in Class B or Class C shares. 

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

Redemption Procedures

	Redemption orders must be transmitted to Lehman Brothers by 
telephone at 1-800-851-3134. Payment for redeemed shares for which 
a redemption order is received by Lehman Brothers before 
3:00 P.M., Eastern time, on a day that both Lehman Brothers and 
the Federal Reserve Bank of Boston are open for business is 
normally made in federal funds wired to the redeeming shareholder 
on the same business day. Payment for redemption orders which are 
received between 3:00 P.M. and 4:00 P.M., Eastern time, is 
normally wired in federal funds on the next business day following 
redemption. 

	Shares are redeemed at the net asset value per share next 
determined after Lehman Brothers' receipt of the redemption order. 
While the Fund intends to use its best efforts to maintain its 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. To allow the Fund's Investment Adviser to manage the 
Fund effectively, investors are strongly urged to initiate all 
investments or redemptions of Fund shares as early in the day as 
possible to notify Lehman Brothers at least one day in advance of 
transactions in excess of $5 million. 

	The Fund reserves the right to wire redemption proceeds 
within seven days after receiving the redemption order if, in the 
judgment of the Investment Adviser, an earlier payment could 
adversely affect the Fund. The Fund 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 Fund 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." 

Valuation of Shares_Net Asset Value

	The Fund's net asset value per share for purposes of pricing 
purchase and redemption orders is determined by the Fund's 
Administrator as of noon, 3:00 P.M. and 4:00 P.M., Eastern time, 
on each weekday, with the exception of those holidays on which 
either Lehman Brothers or the Federal Reserve Bank of Boston is 
closed. Currently, one or both of these institutions 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 by adding the value of all securities and 
other assets of the Fund, subtracting liabilities, and dividing 
the result by the total number of the Fund's outstanding shares 
(irrespective of class or sub-class). In computing net asset 
value, the Fund uses the amortized cost method of valuation as 
described in the Statement of Additional Information under 
"Additional Purchase and Redemption Information." The 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 the Trust's other investment portfolios. 

Other Matters

	Fund shares are sold and redeemed without charge by the 
Fund. 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 the Fund are entitled to dividends and 
distributions arising only from the net investment income and 
capital gains, if any, earned on investments held by the Fund. The 
Fund's net investment income is declared daily as a dividend to 
shares held of record at the close of business on the day of 
declaration. Shares begin accruing dividends on the day the 
purchase order for the shares is effected 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 Fund does 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 Class B and 
Class C shares bear all the expense of fees paid to Service 
Organizations. As a result, at any given time, the net yield on 
Class B and Class C shares will be .25% and .35%, respectively, 
lower than the net yield on Class A shares. 

	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 the Fund's Distributor, 260 Franklin Street, 
15th Floor, Boston, Massachusetts 02110-9624, and will become 
effective after its receipt by the Distributor, with respect to 
dividends paid. 

	The Shareholder Services Group, Inc. ("TSSG"), 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

	The Fund qualified in its last taxable year and intends to 
qualify in future years as a "regulated investment company" under 
the Internal Revenue Code of 1986, as amended (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 the 
Fund distribute to its investors at least 90% of its investment 
company taxable income for such year. In general, the 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 gain for the taxable year over the net 
short-term capital loss, if any, for such year. The 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 
the Fund's distributions will be eligible for the dividends 
received deduction for corporations. The Fund does not expect to 
realize long-term capital gains and, therefore, does not 
contemplate payment of any "capital gain dividends" as described 
in the Code. 

	Dividends declared in October, November or December of any 
year payable to investors of record on a specified date in such 
months will be deemed to have been received by the investors and 
paid by the Fund on December 31 of such year in the event such 
dividends are actually paid during January of the following year. 

	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 the 
Fund and its shareholders. No attempt is made to present a 
detailed explanation of the federal, state or local income tax 
treatment of the Fund or its investors, and this discussion is not 
intended as a substitute for careful tax planning. Accordingly, 
potential investors in the Fund should consult their tax advisers 
with specific reference to their own tax situation. 

MANAGEMENT OF THE FUND

	The business and affairs of the Fund 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 Fund, including agreements 
with its Distributor, Investment Adviser, Administrator, Custodian 
and Transfer Agent. The day-to-day operations of the Fund are 
delegated to the Fund's Investment Adviser and Administrator. The 
Statement of Additional Information relating to the Fund 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 the Fund's shares. 
Lehman Brothers is a wholly-owned subsidiary of Lehman Brothers 
Holdings Inc. ("Holdings"). Prior to May 31, 1994, all of the 
issued and outstanding common stock (representing 92% of the 
voting stock) of Holdings was held by American Express Company. On 
May 31, 1994, American Express distributed to holders of common 
stock of American Express all outstanding shares of common stock 
of Holdings. As of May 31, 1994, Nippon Life Insurance Company 
owned 11.2% 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 Fund. 

Investment Adviser_Lehman Brothers Global Asset Management Inc.

	Lehman Brothers Global Asset Management Inc. ("LBGAM"), 
located at 3 World Financial Center, New York, New York 10285, 
serves as the Fund's Investment Adviser. LBGAM is a wholly owned 
subsidiary of Holdings. LBGAM, together with other Lehman Brother 
investment advisory affiliates, serves as Investment Adviser to 
investment companies and private accounts and has assets under 
management of approximately $15 billion as of March 31, 1994. 

	As Investment Adviser to the Fund, LBGAM will among other 
things, participate in the formulation of the Fund's investment 
policies, analyze economic trends affecting the Fund and monitor 
and evaluate the Fund's investment objective and policies and the 
Fund's investment performance. For its services LBGAM is entitled 
to receive a monthly fee from the Fund at the annual rate of .10% 
of the value of the Fund's average daily net assets. For the 
period February 8, 1993 (commencement of operations) to 
January 31, 1994, LBGAM received no advisory fees from the Fund. 

Administrator and Transfer Agent_The Shareholder Services Group, 
Inc.

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

Custodian_Boston Safe Deposit and Trust Company

	Boston Safe, a wholly owned subsidiary of The Boston 
Company, Inc., located at One Boston Place, Boston, Massachusetts 
02108, serves as the Fund's Custodian. 

Service Organizations

	Financial institutions, such as banks, savings and loan 
associations and other such institutions ("Service Organizations") 
and/or institutional customers of Service Organizations may 
purchase Class B or Class C shares. These shares are identical in 
all respects to Class A shares except that they bear the fees 
described below and enjoy certain exclusive voting rights on 
matters relating to these fees. The Fund will enter into an 
agreement with each Service Organization whose customers 
("Customers") are the beneficial owners of Class B or Class C 
shares that requires the Service Organization to provide certain 
services to Customers in consideration of the Fund's payment of 
service fees at the annual rate of .25% or .35%, respectively, of 
the average daily net asset value of the respective Class 
beneficially owned by Customers. Such services, which are 
described more fully in the Statement of Additional Information 
under "Management of the Fund_Service Organizations," may include 
aggregating and processing purchase and redemption requests from 
Customers and placing net purchase and redemption orders with 
Lehman Brothers; processing dividend payments from the Fund on 
behalf of Customers; providing information periodically to 
Customers showing their positions in shares; arranging for bank 
wires; responding to Customer inquiries relating to the services 
provided by the Service Organization and handling correspondence; 
acting as shareholder of record and nominee; and providing 
reasonable assistance in connection with the distribution of 
shares to Customers. Services provided with respect to Class B 
shares will generally be more limited than those provided with 
respect to Class C shares. Under the terms of the agreements, 
Service Organizations are required to provide to their Customers a 
schedule of any fees that they may charge Customers in connection 
with their investments in Class B or Class C shares. Class A 
shares are sold to financial institutions that have not entered 
into servicing agreements with the Fund in connection with their 
investments. A salesperson and any other person entitled to 
receive compensation for selling or servicing shares of the Fund 
may receive different compensation for selling or servicing one 
Class of shares over another Class. 

Expenses

	The Fund bears all its own expenses. The 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, Securities and Exchange Commission 
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, 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. The 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 during 1994, LBGAM and TSSG have agreed 
voluntarily to reimburse the Fund if and to the extent that the 
Fund's total operating expenses (other than taxes, interest, 
brokerage fees and commissions, Rule 12b-1 fees under the 1940 Act 
and extraordinary expenses) exceed .16% of average daily net 
assets through December 31, 1994. The Investment Adviser and 
Administrator intend to continue voluntarily to waive fees to the 
extent necessary to maintain an annualized expense ratio at a 
level no greater than .18% of average daily net assets thereafter. 
This voluntary reimbursement will not be changed unless investors 
are provided at least 60 days' advance notice. In addition, these 
service providers have agreed to reimburse the Fund to the extent 
required by applicable state law for certain expenses that are 
described in the Statement of Additional Information relating to 
the Fund. Any fees charged by Service Organizations or other 
institutional investors to their customers in connection with 
investments in Fund shares are not reflected in the Fund's 
expenses. 

YIELDS

	From time to time, the "yields" and "effective yields" for 
Class A, Class B and Class C 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 or sub-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 or sub-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 Fund's yields 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 IBC/Donoghue's Money Fund Report, The Wall 
Street Journal and The New York Times, reports prepared by Lipper 
Analytical Service, Inc. and publications of a local or regional 
nature. 

	The 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. Since holders of Class B or 
Class C shares bear the service fees for services provided by 
Service Organizations, the net yield on such shares can be 
expected at any given time to be lower than the net yield on 
Class A shares. 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 the 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 the Fund's yields are described in more 
detail in the Statement of Additional Information. Investors may 
call 1-800-238-2560 (Class A shares code: 001; Class B shares 
code: 101; Class C shares code: 201) 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 offers thirteen portfolios: Prime Money Market Fund 
(Class A, Class B and Class C), Prime Value Money Market Fund 
(Class A, Class B, Class C and Class D), Government Obligations 
Money Market Fund (Class A, Class B, Class C and Class D), 100% 
Government Obligations Money Market Fund (Class A, Class B and 
Class C), Treasury Instruments Money Market Fund (Class A, Class B 
and Class C), Treasury Instruments Money Market Fund II (Class A, 
Class B and Class C), 100% Treasury Instruments Money Market Fund 
(Class A, Class B and Class C), Tax-Free Money Market Fund 
(Class A, Class B, Class C), Municipal Money Market Fund (Class A, 
Class B, Class C and Class D), California Municipal Money Market 
Fund (Class A, Class B and Class C), New York Municipal Money 
Market Fund (Class A, Class B and Class C), Floating Rate U.S. 
Government Fund (Premier and Select Shares) and Short Duration 
U.S. Government Fund (Premier and Select Shares). Shares of the 
New York Municipal Money Market Fund are not currently sold to the 
public. 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 that only Class B or Class C shares, as the case 
may be, 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. Further, 
shareholders of the Fund and of the Trust's other 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. (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

* 	The Expense Summary above has been restated to reflect 
current expected fees and the Fund's Investment Adviser's and 
Administrator's voluntary fee waiver and expense reimbursement 
arrangements in effect for the Fund's fiscal year ending 
January 31, 1995. 



	In order to maintain a competitive expense ratio during 
1994, the Fund's Investment Adviser and Administrator have 
voluntarily agreed to waive fees and reimburse expenses if and to 
the extent that total operating expenses (other than taxes, 
interest, brokerage fees and commissions, Rule 12b-1 fees and 
extraordinary expenses) exceed .16% of average daily net assets 
through December 31, 1994. For 1995 and thereafter, the Investment 
Adviser and Administrator intend to continue voluntarily 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. The voluntary fee waiver and expense 
reimbursement  arrangements described above will not be changed 
unless investors are provided at least 60 days' advance notice. 
The maximum annual contractual fees payable to the Investment 
Adviser and Administrator total .20% of average daily net assets. 
Absent fee waivers, the Total Fund Operating Expenses of Class A, 
Class B and Class C are expected to be .26%, .51% and .61%, 
respectively, of the Funds' average daily net assets.

INVESTMENT OBJECTIVE AND POLICIES

In General

	The Fund's investment objective is 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 its investment objective, the Fund, which 
operates as a diversified investment company, invests 
substantially all of its assets in a diversified portfolio 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"). The Fund will not 
knowingly purchase securities the interest on which is subject to 
federal income tax. Although it has no present intent to do so, 
however, the Fund may invest up to 20% of its assets in securities 
the income from which may be a specific tax preference item for 
purposes of the federal individual and corporate alternative 
minimum tax. See "Taxes." 

	Opinions relating to the validity of Municipal Obligations 
and to the exemption of interest thereon from federal income tax 
are rendered by bond counsel to the respective issuers at the time 
of issuance, and opinions relating to the validity of and the 
tax-exempt status of payments received by the Fund from tax-exempt 
derivative securities are rendered by counsel to the respective 
sponsors of such securities. The Fund and its Investment Adviser 
will rely on such opinions and will not review independently the 
underlying proceedings relating to the issuance of Municipal 
Obligations, the creation of any tax-exempt derivative securities 
or the bases for such opinions. 

 Portfolio Quality and Diversification.  The Fund will purchase 
only Municipal Obligations which are "First Tier Eligible 
Securities" (as defined by the Securities and Exchange Commission) 
and which present minimal credit risks as determined by the 
Investment Adviser pursuant to guidelines approved by the Trust's 
Board of Trustees. First Tier Eligible Securities consist of 
(i) securities that either (a) have short-term debt ratings at the 
time of purchase within the highest rating category assigned by at 
least two unaffiliated nationally recognized statistical rating 
organizations ("NRSROs") (or one NRSRO if the security was rated 
by only one NRSRO), or (b) are issued by issuers with such 
ratings, and (ii) certain securities that are unrated (including 
securities of issuers that have long-term but not short-term 
ratings) but are of comparable quality as determined by the 
Investment Adviser and/or sub-Investment Adviser pursuant to 
guidelines approved by the Trust's Board of Trustees. The Appendix 
to the Statement of Additional Information includes a description 
of applicable NRSRO ratings. 

	Except during temporary defensive periods, the Fund will 
invest substantially all, but in no event less than 80%, of its 
total assets in obligations the interest on which is exempt from 
federal income tax with remaining maturities of thirteen months or 
less as determined in accordance with the rules of the Securities 
and Exchange Commission. The Fund maintains a dollar-weighted 
average portfolio maturity of 90 days or less. The Fund may hold 
uninvested cash reserves pending investment, 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. 

Investment Limitations

	There can be no assurance that the Fund will achieve its 
investment objective. The investment limitations enumerated below 
and the Fund's policy of investing at least 80% of its total 
assets in obligations the interest on which is exempt from federal 
income tax are fundamental and may not be changed by the Trust's 
Board of Trustees without the affirmative vote of the holders of a 
majority of the Fund's outstanding shares. The Fund's investment 
objective and other investment policies described above may be 
changed by the Board of Trustees at any time. If there is a change 
in the investment objective, investors should consider whether the 
Fund remains an appropriate investment in light of their then 
current financial position and needs. (A complete list of the 
investment limitations that cannot be changed without a vote of 
investors is contained in the Statement of Additional Information 
under "Investment Objective and Policies.") 

	The Fund may not: 

	1.	Borrow money except from banks for temporary purposes 
and then in amounts not in excess of 10% of the value of the 
Fund's assets at the time of such borrowing; or mortgage, pledge 
or hypothecate any assets except in connection with any such 
borrowing and in amounts not in excess of the lesser of the dollar 
amounts borrowed or 10% of the value of the Fund's total assets at 
the time of such borrowing. Additional investments will not be 
made 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 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. 

	3.	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, provided that there is no limitation with respect 
to investments in U.S. government securities. 

Types of Municipal Obligations

	The two principal classifications of Municipal Obligations 
which may be held by the Fund 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 are not payable 
from the unrestricted revenues of the issuer. Consequently, the 
credit quality of private activity bonds is usually directly 
related to the credit standing of the corporate user of the 
facility involved. 

	The Tax Reform Act of 1986 substantially revised provisions 
of prior law affecting the issuance and use of proceeds of certain 
tax-exempt obligations. A new definition of private activity bonds 
was applied to many types of bonds, including those which were 
industrial development bonds under prior law. Interest on private 
activity bonds is tax-exempt only if the bonds fall within certain 
defined categories of qualified private activity bonds and meet 
the requirements specified in those respective categories. The Act 
generally did not change the tax treatment of bonds issued to 
finance governmental operations. The changes generally apply to 
bonds issued after August 15, 1986, with certain transitional rule 
exemptions. As used in this Prospectus, the term "private activity 
bonds" also includes industrial development revenue bonds issued 
pursuant to the Internal Revenue Code of 1986, as amended. 

	The Fund's portfolio may also include "moral obligation" 
bonds, which are normally issued by special purpose public 
authorities. If the issuer of moral obligation bonds is unable to 
meet its debt service obligations from current revenues, it may 
draw on a reserve fund, the restoration of which is a moral 
commitment but not a legal obligation of the state or municipality 
which created the issuer. 

Other Investment Practices

	Municipal Obligations purchased by the Fund may include 
variable rate demand notes. Such notes may not be rated by credit 
rating agencies, but unrated notes purchased by the Fund will be 
determined by the Fund's Investment Adviser to be of comparable 
quality at the time of purchase to rated instruments purchasable 
by the Fund. Where necessary to ensure that a note is a First Tier 
Eligible Security, the Fund will require that the issuer's 
obligation to pay the principal of the note be backed by a 
conditional 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 
Fund, the Fund may, upon the 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, in some instances, make it difficult for the Fund 
to dispose of a variable rate demand note if the issuer were to 
default on its payment obligation or during periods that the Fund 
is not entitled to exercise its demand rights, and the Fund could, 
for this or other reasons, suffer a loss to the extent of the 
default. While, in general, the Fund will invest only in 
securities that mature within thirteen months of purchase, the 
Fund may invest in variable rate demand notes which have nominal 
maturities in excess of thirteen months, if such instruments carry 
demand features that comply with conditions established by the 
Securities and Exchange Commission. 

	The Fund may also purchase Municipal Obligations 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 Fund 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 Fund expects that 
commitments to purchase when-issued securities will not exceed 25% 
of the value of its total assets absent unusual market conditions. 
The Fund does not intend to purchase when-issued securities for 
speculative purposes but only in furtherance of its investment 
objective. 

	In addition, the 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 the 
Fund's option specified Municipal Obligations at a specified 
price. The Fund will acquire stand-by commitments solely to 
facilitate portfolio liquidity and does not intend to exercise its 
rights thereunder for trading purposes. 

	Although the Fund may invest more than 25% of its net assets 
in (i) Municipal Obligations whose issuers are in the same state 
and (ii) 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, are issued by issuers 
located in the same state or are private activity bonds, 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. 

	The Fund 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 Fund's Investment 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 
Fund may purchase tender option bonds with different types of 
ownership, payment, credit, and/or liquidity arrangements. 

	The Fund may acquire custodial receipts or certificates 
underwritten by securities dealers or banks that evidence 
ownership of future interest payments, principal payments or both, 
on certain municipal obligations. The underwriter of these 
certificates or receipts typically purchases municipal obligations 
and deposits the obligations in an irrevocable trust or custodial 
account with a custodian bank, which then issues receipts or 
certificates that evidence ownership of the periodic unmatured 
coupon payments and the final principal payment on the 
obligations. Although under the terms of a custodial receipt, the 
Fund would be typically authorized to assert its rights directly 
against the issuer of the underlying obligation, the Fund could be 
required to assert through the custodian bank those rights as may 
exist against the underlying issuer. Thus, in the event the 
underlying issuer fails to pay principal and/or interest when due, 
the Fund may be subject to delays, expenses and risks that are 
greater than those that would have been involved if the Fund had 
purchased a direct obligation of the issuer. In addition, in the 
event that the trust or custodial account in which the underlying 
security has been deposited is determined to be an association 
taxable as a corporation instead of a non-taxable entity, the 
yield on the underlying security would be reduced in recognition 
of any taxes paid. 

	The Fund may purchase from financial institutions tax-exempt 
participation interests in Municipal Obligations. A participation 
interest gives the 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. The 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 Obligation, plus accrued 
interest. The Fund will invest no more than 5% of its total assets 
in participation interests. 

	The Fund will not knowingly invest more than 10% of the 
value of its 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). 
The Fund 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"). The Fund 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 Fund 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 normally is 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 10% limitation on investment in illiquid 
securities. The Fund's Investment Adviser will monitor the 
liquidity of such restricted securities under the supervision of 
the Board of Trustees. See "Investment Objective and 
Policies_Additional Information and Investment Practices_Illiquid 
Securities" in the Statement of Additional Information. 

	The value of the Fund's portfolio securities can be expected 
to vary inversely with changes in prevailing interest rates.

institution placing the order. Payment for Fund shares may be made 
only in federal funds immediately available to Boston Safe. 
(Payment for orders which are not received or accepted by Lehman 
Brothers will be returned after prompt inquiry to the sending 
institution.) The Fund may in its discretion reject any order for 
shares. 

	The minimum aggregate initial investment by an institution 
in the investment portfolios that comprise the Trust is $1 million 
(with not less than $25,000 invested in any one investment 
portfolio offered by the Trust); 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. 

	Conflict of interest restrictions may apply to an 
institution's receipt of compensation paid by the Fund in 
connection with the investment of fiduciary funds in Class B or 
Class C shares. See also "Management of the Fund_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 Securities and 
Exchange Commission, the Department of Labor or state securities 
commissions, are urged to consult their legal advisers before 
investing fiduciary funds in Class B or Class C shares. 

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

Redemption Procedures

	Redemption orders must be transmitted to Lehman Brothers by 
telephone at 1-800-851-3134. Payment for redeemed shares for which 
a redemption order is received by Lehman Brothers before noon, 
Eastern time, on a day that both Lehman Brothers and the Federal 
Reserve Bank of Boston are open for business is normally made in 
federal funds wired to the redeeming investor on the same business 
day. Payment for redeemed shares for which a redemption order is 
received by Lehman Brothers after noon, Eastern time, on such a 
business day is normally made in federal funds wired to the 
redeeming investor on the next business day following redemption. 

	Shares are redeemed at the net asset value per share next 
determined after Lehman Brothers' receipt of the redemption order. 
While the Fund intends to use its best efforts to maintain its net 
asset value per share at $1.00, the net 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. To allow the Fund's Investment Adviser to manage the 
Fund 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. 

	The Fund reserves the right to wire redemption proceeds 
within seven days after receiving the redemption order if, in the 
judgment of the Investment Adviser, an earlier payment could 
adversely affect the Fund. The Fund 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 Fund 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." 

Valuation of Shares_Net Asset Value

	The Fund's net asset value per share for purposes of pricing 
purchase and redemption orders is determined by the Fund's 
Administrator as of noon and 4:00 P.M., Eastern time, 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. Currently, one or both of these institutions 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 the Fund 
is calculated by adding the value of all securities and other 
assets of the Fund, subtracting liabilities, and dividing the 
result by the total number of the Fund's outstanding shares 
(irrespective of class or sub-class). In computing net asset 
value, the Fund uses the amortized cost method of valuation as 
described in the Statement of Additional Information under 
"Additional Purchase and Redemption Information." The Fund's net 
asset value per share for purposes of pricing purchase and 
redemption orders is determined independently of the net asset 
value of the Trust's other investment portfolios. 

Other Matters

	Fund shares are sold and redeemed without charge by the 
Fund. 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 the Fund are entitled to dividends and 
distributions arising only from the net investment income and 
capital gains, if any, earned on investments held by the Fund. The 
Fund's net investment income is declared daily as a dividend to 
shareholders of record at the close of business on the day of 
declaration. Shares begin accruing dividends on the day the 
purchase order for the shares is effected 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 Fund does 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 Class B and 
Class C shares bear all the expense of fees paid to Service 
Organizations. As a result, at any given time, the net yield on 
Class B and Class C shares will be .25% and .35%, respectively, 
lower than the net yield on Class A shares. 

	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 the Fund's Distributor, at 260 Franklin Street, 
15th Floor, Boston, Massachusetts 02110-9624, and will become 
effective after its receipt by the Distributor, with respect to 
dividends paid. 

	The Shareholder Services Group, Inc. ("TSSG"), 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

	The Fund qualified in its last taxable year and intends to 
qualify in future years as a "regulated investment company" under 
the Internal Revenue Code of 1986, as amended (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 the 
Fund distribute to its investors at least the sum of 90% of its 
exempt-interest income net of certain deductions and 90% of its 
investment company taxable income for such year. Dividends derived 
from exempt-interest income 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. (See the Statement of Additional Information under 
"Additional Information Concerning Taxes.") 

	If the Fund should hold 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 their federal 
alternative minimum taxable income for purposes of determining 
liability (if any) for the 24% alternative minimum tax applicable 
to individuals and the 20% alternative minimum tax and the 
environmental tax applicable to corporations. 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 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. Under state or local law, the Fund's distributions of net 
investment income may be taxable to investors as dividend income 
even though a substantial portion of such distributions may be 
derived from interest on tax-exempt obligations which, if realized 
directly, would be exempt from such income taxes. 

	Dividends declared in October, November or December of any 
year payable to investors of record on a specified date in such 
months will be deemed to have been received by the investors and 
paid by the Fund on December 31 of such year in the event such 
dividends are actually paid during January of the following year. 

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

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

MANAGEMENT OF THE FUND

	The business and affairs of the Fund 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 Fund, including agreements 
with its Distributor, Investment Adviser, Administrator, Custodian 
and Transfer Agent. The day-to-day operations of the Fund are 
delegated to the Fund's Investment Adviser and Administrator. The 
Statement of Additional Information relating to the Fund 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 the Fund's shares. 
Lehman Brothers is a wholly-owned subsidiary of Lehman Brothers 
Holdings Inc. ("Holdings"). Prior to May 31, 1994, all of the 
issued and outstanding common stock (representing 92% of the 
voting stock) of Holdings was held by American Express Company. On 
May 31, 1994, American Express distributed to holders of common 
stock of American Express all outstanding shares of common stock 
of Holdings. As of May 31, 1994, Nippon Life Insurance Company 
owned 11.2% 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 Fund. 

Investment Adviser_Lehman Brothers Global Asset Management Inc.

	Lehman Brothers Global Asset Management Inc. ("LBGAM"), 
located at 3 World Financial Center, New York, New York, 10285, 
serves as the 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 $15 billion as of March 31, 1994. 

	As Investment Adviser to the Fund, LBGAM will among other 
things, participate in the formulation of the Fund's investment 
policies, analyze economic trends affecting the Fund and monitor 
and evaluate the Fund's investment objective and policies and the 
Fund's investment performance. For its services LBGAM is entitled 
to receive a monthly fee from the Fund at the annual rate of .10% 
of the value of the Fund's average daily net assets. For the 
period February 8, 1993 (commencement of operations) to 
January 31, 1994, LBGAM received no advisory fees from the Fund. 

Administrator and Transfer Agent_The Shareholder Services Group, 
Inc.

	The Shareholder Services Group, Inc. ("TSSG"), located at 
One Exchange Place, 53 State Street, Boston, Massachusetts 02109, 
serves as the Fund's Administrator and Transfer Agent. TSSG is a 
wholly owned subsidiary of First Data Corporation. As 
Administrator, TSSG calculates the net asset value of the Fund's 
shares and generally assists in all aspects of the Fund's 
administration and operation. As compensation for TSSG's services 

as Administrator, TSSG is entitled to receive from the Fund a 
monthly fee at the annual rate of .10% of the value of the Fund's 
average daily net assets. TSSG is also entitled to receive a fee 
from the Fund for its services as Transfer Agent. TSSG pays Boston 
Safe, the Fund's Custodian, a portion of its monthly 
administration fee for custody services rendered to the Fund. 

Custodian_Boston Safe Deposit and Trust Company

	Boston Safe, a wholly owned subsidiary of The Boston 
Company, Inc., located at One Boston Place, Boston, Massachusetts 
02108, serves as the Fund's Custodian.

Service Organizations

	Financial institutions such as banks, savings and loan 
associations and other such institutions ("Service Organizations") 
and/or institutional customers of Service Organizations may 
purchase Class B or Class C shares. These shares are identical in 
all respects to Class A shares except that they bear the fees 
described below and enjoy certain exclusive voting rights on 
matters relating to these fees. The Fund will enter into an 
agreement with each Service Organization whose customers 
("Customers") are the beneficial owners of Class B or Class C 
shares that requires the Service Organization to provide certain 
services to Customers in consideration of the Fund's payment of 
service fees at the annual rate of .25% or .35%, respectively of 
the average daily net asset value of the respective Class 
beneficially owned by Customers. Such services, which are 
described more fully in the Statement of Additional Information 
under "Management of the Fund_Service Organizations," may include 
aggregating and processing purchase and redemption requests from 
Customers and placing net purchase and redemption orders with 
Lehman Brothers; processing dividend payments from the Fund on 
behalf of Customers; providing information periodically to 
Customers showing their positions in shares; arranging for bank 
wires; responding to Customer inquiries relating to the services 
provided by the Service Organization and handling correspondence; 
acting as investor of record and nominee; and providing reasonable 
assistance in connection with the distribution of shares to 
Customers. Services provided with respect to Class B shares will 
generally be more limited than those provided with respect to 
Class C shares. Under the terms of the agreements, Service 
Organizations are required to provide to their Customers a 
schedule of any fees that they may charge Customers in connection 
with their investments in Class B or Class C shares. Class A 
shares are sold to financial institutions that have not entered 
into servicing agreements with the Fund in connection with their 
investments. A salesperson and any other person entitled to 
receive compensation for selling or servicing shares of the Fund 
may receive different compensation for selling or servicing one 
Class of shares over another Class. 

Expenses

	The Fund bears all of its own expenses. The 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, Securities and Exchange Commission 
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, transfer agent and dividend disbursing agent, Service 
Organization fees, certain insurance premiums, outside auditing 
and legal expenses, costs of investor reports and investor 
meetings and any extraordinary expenses. The 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 during 1994, LBGAM and TSSG have agreed 
voluntarily to reimburse the Fund if and to the extent that the 
Fund's total operating expenses (other than taxes, interest, 
brokerage fees and commissions, Rule 12b-1 fees under the 1940 Act 
and extraordinary expenses) exceed .16% of average daily net 
assets through December 31, 1994. The Investment Adviser and 
Administrator intend to continue voluntarily to waive fees to the 
extent necessary to maintain an annualized expense ratio at a 
level no greater than .18% of average daily net assets thereafter. 
This voluntary reimbursement will not be changed unless investors 
are at a level provided at least 60 days' advance notice. In 
addition, these service providers have agreed to reimburse the 
Fund to the extent required by applicable state law for certain 
expenses that are described in the Statement of Additional 
Information relating to the Fund. Any fees charged by Service 
Organizations or other institutional investors to their customers 
in connection with investments in Fund shares are not reflected in 
the Fund's expenses. 

YIELDS

	From time to time, the "yields," "effective yields" and 
"tax-equivalent yields" for Class A, Class B or Class C shares may 
be quoted in advertisements or in reports to investors. Yield 
quotations are computed separately for each Class of shares. The 
"yield" quoted in advertisements for a particular class or 
sub-class of shares refers to the income generated by an 
investment in such shares of 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 or sub-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 the Fund's 
tax-free yield for each class or sub-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 ." 

	The Fund's yields 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, 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. For example, such data are reported in national 
financial publications such as IBC/Donoghue's Money Fund Report, 
Ibbotson Associates of Chicago, The Wall Street Journal and The 
New York Times, reports prepared by Lipper Analytical Services, 
Inc. and publications of a local or regional nature. 

	The 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. Since holders of Class B and 
Class C shares bear the service fees for services provided by 
Service Organizations, the net yield on such shares can be 
expected at any given time to be lower than the net yield on 
Class A shares. 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 the Fund's 
expenses or yields. The methods used to compute the Fund's yields 
are described in more detail in the Statement of Additional 
Information. Investors may call 1-800-238-2560 (Class A shares 
code: 008; Class B shares code: 108; Class C shares code: 208) to 
obtain current yield information. 

DESCRIPTION OF SHARES

	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 offers thirteen portfolios: Prime Money Market Fund 
(Class A, Class B and Class C), Prime Value Money Market Fund 
(Class A, Class B, Class C and Class D), Government Obligations 
Money Market Fund (Class A, Class B, Class C and Class D), 100% 
Government Obligations Money Market Fund (Class A, Class B and 
Class C), Treasury Instruments Money Market Fund (Class A, Class B 
and Class C), Treasury Instruments Money Market Fund II (Class A, 
Class B and Class C), 100% Treasury Instruments Money Market Fund 
(Class A, Class B and Class C), Tax-Free Money Market Fund 
(Class A, Class B and Class C), Municipal Money Market Fund 
(Class A, Class B, Class C and Class D), California Municipal 
Money Market Fund (Class A, Class B and Class C), New York 
Municipal Money Market Fund (Class A, Class B and Class C), 
Floating Rate U.S. Government Fund (Premier and Select Shares), 
and Short Duration U.S. Government Fund (Premier and Select 
Shares). Shares of the New York Municipal Money Market Fund are 
not currently sold to the public. 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 investors except as required by the 1940 Act or other 
applicable law. The Trust will call a meeting of investors for the 
purpose of voting upon the question of removal of a member of the 
Board of Trustees upon written request of investors 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, 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 that only Class B or Class C shares, as the case 
may be, will be entitled to vote on matters submitted to a vote of 
investors pertaining to the Fund's arrangements with Service 
Organizations with respect to the relevant Class. Further, 
investors of all of the Fund and 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 
investors 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.) Investors 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."

BACKGROUND AND EXPENSE INFORMATION

	The following Expense Summary lists the costs and expenses 
that an investor in the Fund can expect to incur during the Fund's 
current fiscal year ending January 31, 1995. The Fund offers three 
separate classes of shares. Shares of each class represent equal, 
pro rata interests in the Fund and accrue daily dividends in the 
same manner except that Class B and C shares bear fees payable by 
the Fund (at the rate of .25% and .35% per annum, respectively) to

* 	The Expense Summary above has been restated to reflect the 
Fund's Investment Adviser's and Administrator's Voluntary 
reimbursement arrangements in effect for the Fund's fiscal year 
ending January 31, 1995. With respect to Class A, Class B and 
Class C share for the month of January, 1995, the Total Fund 
Operating Expenses including reimbursement of expenses are 
anticipated to be .18%, .43%, and .53%, respectively.

	In order to maintain a competitive expense ratio during 
1994, the Funds' Investment Adviser and Administrator have 
voluntarily agreed to reimburse the Fund if and to the extent that 
total operating expenses (other than taxes, interest, brokerage 
fees and commissions, Rule 12b-1 fees and extraordinary expenses) 
exceed .16% of average daily net assets through December 31, 1994. 
For the years 1995-1997, the Investment Adviser and Administrator 
intend to continue voluntarily to reimburse the Fund to the extent 
necessary to maintain an annualized expense ratio at a level no 
greater than .18% of average daily net assets. The voluntary 
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 Investment 
Adviser and Administrator total .20% of average daily net assets. 
Absent reimbursement of expenses, the Total Fund Operating 
Expenses of Class A, Class B and Class C would be .25%, .50% and 
.60%, respectively, of the Fund's average daily net assets.

#	Total net assets for Class B was $100 at January 31, 1994.

INVESTMENT OBJECTIVE AND POLICIES

	The Fund's investment objective is current income with 
liquidity and security of principal. The Fund, which operates as a 
diversified investment company, invests solely in direct 
obligations of the U.S. Treasury, such as Treasury bills and notes 
and repurchase agreements relating to direct Treasury obligations. 
The Fund invests only in securities which are purchased with and 
payable in U.S. dollars (i.e., U.S. dollar denominated securities) 
and which have (or, pursuant to regulations adopted by the 
Securities and Exchange Commission, are deemed to have) remaining 
maturities of 13 months or less at the date of purchase by the 
Fund. The Fund maintains a dollar-weighted average portfolio 
maturity of 90 days or less. 

	Securities issued or guaranteed by the U.S. Government have 
historically involved little risk of loss of principal if held to 
maturity. However, due to fluctuations in interest rates, the 
market value of such securities may vary during the period a 
shareholder owns shares of the Fund. Certain government securities 
held by the Fund may have remaining maturities exceeding thirteen 
months if such securities provide for adjustments in their 
interest rates not less frequently than every thirteen months. 

	The Fund may purchase government securities from financial 
institutions, such as banks and broker-dealers, subject to the 
seller's agreement to repurchase them at an agreed upon time and 
price ("repurchase agreements"). The Fund will not invest more 
than 10% of the value of its net assets in repurchase agreements 
which do not provide for settlement within 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 Fund to 
possible loss because of adverse market action or delay in 
connection with the disposition of the underlying obligations. 

	The 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 Fund would sell portfolio securities to financial 
institutions and agree to repurchase them at an agreed upon date 
and price. The Fund would consider entering into reverse 
repurchase agreements to avoid otherwise selling securities during 
unfavorable market conditions to meet redemptions. Reverse 
repurchase agreements involve the risk that the market value of 
the portfolio securities sold by the Fund may decline below the 
price of the securities the Fund is obligated to repurchase. 

	The 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 
Fund 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 Fund expects that commitments to purchase 
when-issued securities will not exceed 25% of the value of its 
total assets absent unusual market conditions. The Fund does not 
intend to purchase when-issued securities for speculative purposes 
but only in furtherance of its investment objective. 

	The Fund may also lend its portfolio securities to financial 
institutions in accordance with the investment restrictions 
described below. The Fund may lend portfolio securities against 
collateral consisting of cash or securities which are consistent 
with the Fund's permitted investments, which is equal at all times 
to at least 100% of the value of the securities loaned. There is 
no limitation on the amount of securities that may be loaned. Such 
loans would involve risks of delay in receiving additional 
collateral or in recovering the securities loaned or even loss of 
rights in the collateral should the borrower of the securities 
fail financially. However, loans  will be made only to borrowers 
deemed by the Fund's investment adviser to be of good standing and 
only when, in the adviser's judgment, the income to be earned from 
the loans justifies the attendant risks. 

	There can be no assurance that the Fund will achieve its 
investment objective. 

Investment Limitations

	The Fund's investment objective and policies described above 
are not fundamental and may be changed by the Trust's Board of 
Trustees without a vote of shareholders. If there is a change in 
the investment objective, shareholders should consider whether the 
Fund remains an appropriate investment in light of their then 
current financial position and needs. The Fund's borrowing 
limitation summarized below may not be changed without the 
affirmative vote of the holders of majority of its outstanding 
shares. (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 Objective 
and Policies.") 

	The Fund may not borrow money except from banks for 
temporary purposes and then in an amount not exceeding 10% of the 
value of the Fund's total assets, or mortgage, pledge or 
hypothecate its assets except in connection with any such 
borrowing and in amounts not in excess of the lesser of the dollar 
amounts borrowed or 10% of the value of the Fund's total assets at 
the time of such borrowing. Additional investments will not be 
made when borrowings exceed 5% of the Fund's assets. 

PURCHASE AND REDEMPTION OF SHARES

Purchase Procedures

	Shares of the Fund 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 by the Fund only on days on which 
both Lehman Brothers and the Federal Reserve Bank of Boston are 
open for business and must be transmitted to Lehman Brothers, by 
telephone at 800-851-3134. Orders received before noon, Eastern 
time, for which payment has been received by Boston Safe Deposit 
and Trust Company ("Boston Safe"), the Fund's custodian, will be 
executed at noon. Orders received between noon and 3:00 P.M., 
Eastern time, will be executed at 3:00 P.M., Eastern time, if 
payment has been received by Boston Safe by 3:00 P.M. and will be 
executed at 4:00 P.M. if payment has been received by 4:00 P.M.  
Orders received after 3:00 P.M. and orders for which payment has 
not been received by 4:00 P.M., Eastern time, will not be accepted 
and notice thereof will be given to the institution placing the 
order. Payment for Fund shares may be made only in federal funds 
immediately available to Boston Safe. (Payment for orders which 
are not received or accepted by Lehman Brothers will be returned 
after prompt inquiry to the sending institution.) The Fund may in 
its discretion reject any order for shares. 

	The minimum aggregate initial investment by an institution 
in the investment portfolios that comprise the Trust is $1 million 
(with not less than $25,000 invested in any one investment 
portfolio offered by the Trust); 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. 

	Conflict of interest restrictions may apply to an 
institution's receipt of compensation paid by the Fund on 
fiduciary funds that are invested in Class B or Class C shares. 
See also "Management of the Fund_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 Securities and Exchange Commission, the 
Department of Labor or state securities commissions, should 
consult their legal advisors before investing fiduciary funds in 
Class B or Class C shares. 

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

Redemption Procedures

	Redemption orders must be transmitted to Lehman Brothers at 
1-800-581-3134. Payment for redeemed shares for which a redemption 
order is received by Lehman Brothers before 3:00 P.M., Eastern 
time, on a day that both Lehman Brothers and the Federal Reserve 
Bank of Boston are open for business is normally made in federal 
funds wired to the redeeming shareholder on the same business day. 
Payment for other redemption orders which are received between 
3:00 P.M. and 4:00 P.M., Eastern time, is normally wired in 
federal funds on the next business day following redemption. 

	Shares are redeemed at the net asset value per share next 
determined after Lehman Brothers' receipt of the redemption order. 
While the Fund intends to use its best efforts to maintain its net 
asset value per share at $1.00, the proceeds paid to a shareholder 
upon redemption may be more or less than the amount invested 
depending upon a share's net asset value at the time of 
redemption. To allow the Fund's investment adviser and 
sub-investment adviser to manage the Fund 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. 

	The Fund reserves the right to wire redemption proceeds 
within seven days after receiving the redemption order if, in the 
judgment of the Investment Adviser, an earlier payment could 
adversely affect the Fund. The Fund 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 sixty days' 
prior written notice to the shareholder. Any such redemption shall 
be effected at the net asset value per share next determined after 
the redemption order is entered. If during the sixty-day period 
the shareholder increases the value of its account to $10,000 or 
more, no such redemption shall take place. In addition, the Fund 
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." 

Valuation of Shares_Net Asset Value

	The Fund's net asset value per share for purposes of pricing 
purchase and redemption orders is determined by the Fund's 
administrator as of noon, 3:00 P.M. and 4:00 P.M., Eastern time, 
on each weekday, with the exception of those holidays on which 
either Lehman Brothers or the Federal Reserve Bank of Boston is 
closed. Currently, one or both of these institutions are closed on 
customary national business holidays of New Year's Day, Martin 
Luther King, Jr. Day, Presidents' Day (Washington's Birthday), 
Good Friday, Memorial Day (observed), Independence Day (observed), 
Labor Day, Columbus Day, 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 the Fund is 
calculated by adding the value of all securities and other assets 
belonging to the Fund, subtracting liabilities and dividing the 
result by the total number of the Fund's outstanding shares. In 
computing net asset value, the Fund uses the amortized cost method 
of valuation as described in the Statement of Additional 
Information under "Additional Purchase and Redemption 
Information." The 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 the Trust's other 
investment portfolios. 

Other Matters

	Fund shares are sold and redeemed without charge by the 
Fund. 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 shares on behalf of its 
customers is responsible for transmitting orders to Lehman 
Brothers in accordance with its customer agreements. 

MANAGEMENT OF THE FUND

	The business and affairs of the Fund 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 Fund, including agreements 
with its Distributors, Investment Adviser, Administrator, 
Custodian and Transfer Agent. The day-to-day operations of the 
Fund are delegated to the Fund's Investment Adviser and 
Administrator. The Statement of Additional Information relating to 
the Fund contains general background information regarding each 
Trustee and executive officer of the Trust. 

Distributor

	Lehman Brothers, located at Three World Financial Center, 
New York, New York 10285, is the Distributor of the Fund's shares. 
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 Fund. 

Investment Adviser_Lehman Brothers Global Asset Management Inc.

	Lehman Brothers Global Asset Management Inc. ("LBGAM"), 
located at 3 World Financial Center, New York, New York 10285, 
serves as the Fund's Investment Adviser. LBGAM is a wholly owned 
subsidiary of Lehman Brothers Holdings Inc. ("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 in excess of 
$15 billion. 

	As Investment Adviser to the Fund, LBGAM will, among other 
things, participate in the formulation of the Fund's investment 
policies, analyze economic trends affecting the Fund and monitor 
and evaluate the Fund's investment objective and policies and the 
Fund's performance. For its services LBGAM will be paid a monthly 
fee by the Fund at the annual rate of .10% of the value of the 
Fund's average daily net assets. For the period February 8, 1993 
(commencement of operations) to January 31, 1994, LBGAM received 
an advisory fee from the Fund in the amount of .      % of average 
daily net assets. 

Administrator and Transfer Agent_Shareholder Services Group

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

Custodian_Boston Safe Deposit and Trust Company

	Boston Safe, a wholly owned subsidiary of The Boston 
Company, Inc., located at One Boston Place, Boston, Massachusetts 
02108, serves as the Fund's Custodian. 

Service Organizations

	Institutional investors, such as banks, savings and loan 
associations and other financial institutions ("Service 
Organizations") and/or institutional customers of Service 
Organizations may purchase Class B or Class C shares.  These 
shares are identical in all respects to Class A shares except that 
they bear the fees described below and enjoy certain exclusive 
voting rights on matters relating to these fees. The Fund will 
enter into an agreement with each Service Organization whose 
customers ("Customers") are the beneficial owners of Class B or 
Class C shares that requires the Service Organization to provide 
certain services to Customers in consideration of the Fund's 
payment of service fees at the annual rate of .25% or .35%, 
respectively of the average daily net asset value of the 
respective class beneficially owned by Customers. Such 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 Customers and placing net purchase and redemption 
orders with Lehman Brothers; processing dividend payments from the 
Fund on behalf of Customers; providing information periodically to 
Customers showing their positions in shares; arranging for bank 
wires; responding to customer inquiries relating to the services 
provided by the Service Organization and handling correspondence; 
and acting as shareholder of record and nominee; and providing 
reasonable assistance in connection with the distribution of 
shares to Customers. Services provided with respect to Class B 
shares will generally be more limited than those provided with 
respect to Class C shares. Under the terms of the agreements, 
Service Organizations are required to provide to their Customers a 
schedule of any fees that they may charge Customers in connection 
with their investments in Class B or Class C shares. Class A 
shares are sold to institutions that have not entered into 
servicing agreements with the Fund in connection with their 
investments. A salesperson and any other person entitled to 
receive compensation for selling or servicing shares of the Fund 
may receive different compensation for selling or servicing one 
Class of shares over another Class. 

Expenses

	The Fund bears all of its own expenses. The 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, Securities and Exchange Commission 
fees, state securities qualification fees, costs of preparing and 
printing prospectuses for regulatory purposes and for distribution 
to shareholders, advisory and administration fees, charges of the 
custodian, 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. The 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 during 1994, LBGAM, and TSSG have agreed 
voluntarily to reimburse the Fund if and to the extent that the 
Fund's total operating expenses (other than taxes, interest, 
brokerage fees and commissions, Rule 12b-1 fees under the 1940 Act 
and extraordinary expenses) exceed .16% of average daily net 
assets through December 31, 1994. The investment adviser and 
administrator intend to continue voluntarily to reimburse the Fund 
to the extent necessary to maintain an annualized expense ratio at 
a level no greater than .18% of average daily net assets 
thereafter. This voluntary reimbursement will not be changed 
unless shareholders are provided at least 60 days' advance notice. 
In addition, these service providers have agreed to reimburse the 
Fund to the extent required by applicable state law for certain 
expenses that are described in the Statement of Additional 
Information relating to the Fund. Any fees charged by Service 
Organizations or other institutional investors to their customers 
in connection with investments in Fund shares are not reflected in 
the Fund's expenses. 

DIVIDENDS

	Shareholders of the Fund are entitled to dividends and 
distributions arising only from the net investment income and 
capital gains, if any, earned on its investments held by the Fund. 
The Fund's net investment income is declared daily as a dividend 
to shares held of record at the close of business on the day of 
declaration. Shares begin accruing dividends on the day the 
purchase order for the shares is effected 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 a shareholder's shares of a particular 
class. The Fund does 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 share of the Fund except that Class B and 
Class C shares bear all the expense of fees paid to Service 
Organizations. As a result, at any given time, the net yield on 
Class B and Class C shares will be .25% and .35%, respectively, 
lower than the net yield on Class A shares. 

	Institutional shareholders may elect to have their dividends 
reinvested in additional full and fractional shares of the same 
class 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 the Fund's Distributor at 260 Franklin Street, 
15th Floor, Boston, Massachusetts 02110-9624, and will become 
effective after its receipt by TSSG with respect to dividends 
paid. 

	TSSG, as transfer agent, will send each Fund shareholder or 
its authorized representative an annual statement designating the 
amount, if any, of any dividends and distributions made during 
each year and their federal tax qualification. 

TAXES

	The Fund qualified in its last taxable year and intends to 
qualify each year as a "regulated investment company" under the 
Internal Revenue Code of 1986, as amended (the "Code"). A 
regulated investment company is exempt from federal income tax on 
amounts distributed to its shareholders. 

	Qualification as a regulated investment company under the 
Code for a taxable year requires, among other things, that the 
Fund distribute to its shareholders at least 90% of its investment 
company taxable income for such year. In general, the Fund's 
investment company taxable income will be its taxable income 
(including interest) 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. The 
Fund intends to distribute substantially all of its investment 
company taxable income each year. Such distributions will be 
taxable as ordinary income to the Fund's shareholders 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 the Fund's distributions will be eligible 
for the dividends received deduction for corporations. The Fund 
does not expect to realize long-term capital gains and therefore 
does not expect to distribute any "capital gain dividends" as 
described in the Code. 

	Dividends declared in October, November or December of any 
year payable to shareholders of record on a specified date in such 
months will be deemed to have been received by the shareholders 
and paid by the Fund on December 31 of such year in the event such 
dividends are actually paid during January of the following year. 

	Many states, by statute, judicial decision or administrative 
action, have taken the position that dividends of a regulated 
investment company such as the Fund that are attributable to 
interest on obligations of the U.S. Treasury and certain 
U.S. Government agencies and instrumentalities are the functional 
equivalent of interest from such obligations and are, therefore, 
exempt from state and local income taxes.

	The Fund will provide investors annually with information 
about the portion of dividends from the Fund derived from 
U.S. Treasury and U.S. Government agency obligations. Investors 
should be aware of the application of their state and local tax 
laws to investments in the Fund.

	The foregoing is only a brief summary of some of the 
important federal tax considerations generally affecting the Fund 
and its shareholders. As indicated above, IRAs receive special tax 
treatment. No attempt is made to present a detailed explanation of 
the federal, state or local income tax treatment of the Fund or 
its shareholders and this discussion is not intended as a 
substitute for careful tax planning. Accordingly, potential 
investors in the Fund should consult their tax advisors with 
specific reference to their own tax situation. 

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 offers twelve portfolios: Prime Money Market Fund (Class A, 
Class B and Class C), Prime Value Money Market Fund (Class A, 
Class B, Class C and Class D), Government Obligations Money Market 
Fund (Class A, Class B, Class C and Class D), 100% Government 
Obligations Money Market Fund (Class A, Class B and Class C), 
Treasury Instruments Money Market Fund II (Class A, Class B and 
Class C), 100% Treasury Instruments Money Market Fund (Class A, 
Class B and Class C), Tax-Free Money Market Fund (Class A, Class B 
and Class C), Municipal Money Market Fund (Class A, Class B, 
Class C and Class D), California Municipal Money Market Fund 
(Class A, Class B and Class C), New York Municipal Money Market 
Fund (Class A, Class B and Class C), Floating Rate U.S. Government 
Fund (Class A and Class B) and Short Duration U.S. Government Fund 
(Class A and Class B). Shares of the New York Municipal Money 
Market Fund are not currently sold to the public. The Declaration 
of Trust further authorizes the trustees to classify or reclassify 
any class of shares into one or more sub-classes. 

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

	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, shares will be 
fully paid and nonassessable. 

	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 that only Class B or Class C shares, as the case 
may be, 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. 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. (See the Statement of Additional Information 
under "Miscellaneous" 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." 

YIELDS

	From time to time the "yields" and "effective yields" for 
Class A, Class B and Class C shares may be quoted in 
advertisements or in reports to investors. Yield figures are based 
on historical earnings and are not intended to indicate future 
performance. The "yield" quoted in advertisements for a particular 
class or sub-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 week 
over a 52-week period or one-year 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 or sub-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. Yield 
quotations are computed separately for each Class of shares. 

	The Fund's yields may be compared to those of other mutual 
funds with similar objectives, to stock or 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 IBC/Donoghue's Money Fund Report, The Wall 
Street Journal and The New York Times, reports prepared by Lipper 
Analytical Service, Inc. and  publications of a local or regional 
nature. 

	The 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. Since holders of Class B or 
Class C shares bear the service fees for services provided by 
Service Organizations, the net yield on such shares can be 
expected at any given time to be lower than the net yield on 
Class A shares. 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 the Fund's 
expenses or yields. The methods used to compute the Fund's yields 
are described in more detail in the Statement of Additional 
Information. Investors may call 800-238-2560 (Class A shares code: 
005; Class B shares code: 105; Class C shares code: 205) to obtain 
current yield information.
