PROSPECTUS

California 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 
California Municipal Money Market Fund portfolio (the "Fund"), one 
of a family of portfolios of the Trust. 

	The Fund's investment objective is to provide California 
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 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 shares and 
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 
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.

* 	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 
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 Global Asset Management

	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 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."
