portfolio.

INVESTMENT OBJECTIVE
AND POLICIES
     ___________________________________________________________________________
 
                     The Portfolio's investment objective is to preserve
                     principal value and maintain a high degree of liquidity
                     while providing current income exempt from federal income
                     taxes. There can be no assurance that the Portfolio will
                     meet its investment objective.
 
                           The Portfolio invests in U.S. dollar denominated
                     municipal securities of issuers located in all fifty
                     states, the District of Columbia, Puerto Rico and other
                     U.S. territories and possessions (collectively, "Municipal
                     Securities"). It is a fundamental policy of the Portfolio
                     to invest at least 80% of its net assets in securities the
                     interest on which is exempt from federal income taxes,
                     based on opinions from bond counsel for the issuers, and
                     the Portfolio will invest, under normal conditions, at
                     least 80% of its net assets in securities the interest on
                     which is not a preference item for purposes of the federal
                     alternative minimum tax.
 
                           The Portfolio may purchase municipal bonds, municipal
                     notes and tax-exempt commercial paper, but only if such
                     securities, at the time of purchase, meet the quality,
                     maturity and diversification requirements imposed by Rule
                     2a-7. See "General Investment Policies."
 
                           The Adviser will not invest more than 25% of
                     Portfolio assets in Municipal Securities (a) whose issuers
                     are located in the same state or (b) the interest on which
                     is derived from revenues of similar type projects. This
                     restriction does not apply to Municipal Securities in any
                     of the following categories: public housing authorities;
                     general obligations of states and localities; state and
                     local housing finance authorities or municipal utilities
                     systems.
 
                           There could be economic, business, or political
                     developments which might affect all Municipal Securities of
                     a similar type. To the extent that a significant portion of
                     the Portfolio's assets are invested in Municipal Securities
                     payable from revenues on similar projects, the Portfolio
                     will be subject to the peculiar risks presented by such
                     projects to a greater extent than it would be if the
                     Portfolio's assets were not so invested. Moreover, in
 
                                                                               4
<PAGE>
                     seeking to attain its investment objective, the Portfolio
                     may invest all or any part of its assets in Municipal
                     Securities that are industrial development bonds.
 
GENERAL INVESTMENT
POLICIES
     ___________________________________________________________________________
 
                     In purchasing obligations, the Portfolio complies with the
                     requirements of Rule 2a-7 under the Investment Company Act
                     of 1940 (the "1940 Act"), as that Rule may be amended from
                     time to time. These requirements currently provide that the
                     Portfolio must limit its investments to securities with
                     remaining maturities of 397 days or less, and must maintain
                     a dollar-weighted average maturity of 90 days or less. In
                     addition, the Portfolio may only invest in eligible
                     securities. In general, this means securities rated in one
                     of the two highest categories for short-term securities by
                     at least two nationally recognized statistical rating
                     organizations ("NRSROs") (or by one NRSRO if only one NRSRO
                     has rated the security), or, if unrated, determined by
                     Weiss, Peck & Greer, L.L.C. (the "Adviser"), to be of
                     equivalent quality. Since the Portfolio often purchases
                     securities supported by credit enhancements from banks and
                     other financial institutions, changes in the credit quality
                     of these institutions could cause losses to the Portfolio
                     and affect its share price.
 
                           Securities rated in the highest rating category
                     (E.G., A-1 by Standard & Poor's Corporation ("S&P")) by at
                     least two NRSROs (or, if unrated, determined by the Adviser
                     to be of comparable quality) are "first tier" securities.
                     Non-first tier securities rated in the second highest
                     rating category (E.G., A-2 by S&P) by at least one NRSRO
                     (or, if unrated, determined by the Adviser to be of
                     comparable quality) are considered to be "second tier"
                     securities. The Portfolio's investments in non-first tier
                     conduit securities will be limited to 5% of the Portfolio's
                     assets. Conduit securities are securities issued to finance
                     non-governmental private projects, such as housing
                     developments and retirement homes, and for which the
                     ultimate obligor is not a governmental issuer.
 
                           The Portfolio may purchase securities on a
                     "when-issued" basis, and reserves the right to engage in
                     transactions involving standby commitments. While the
                     Portfolio generally intends to be fully invested in
                     federally tax-exempt securities, the Portfolio may invest
                     up to 20% of its net assets in taxable money market
                     instruments (including repurchase agreements) and
                     securities the interest on which is a preference item for
                     purposes of the federal alternative minimum tax. The
                     Portfolio will not invest more than 10% of its total assets
                     in securities which are considered to be illiquid.

LIMITATIONS
        ________________________________________________________________________
 
                     The investment objective and investment limitations are
                     fundamental policies of the Portfolio. Fundamental policies
                     cannot be changed with respect to the Trust or the
                     Portfolio without the consent of the holders of a majority
                     of the Trust's or the Portfolio's outstanding shares. It is
                     a fundamental policy of the Portfolio to use its best
                     efforts to maintain a constant net asset value of $1.00 per
                     share.
 
                     THE PORTFOLIO MAY NOT:
 
                     1. Purchase securities of any issuer (except securities
                        issued or guaranteed by the United States Government,
                        its agencies or instrumentalities) if, as a result, more
                        than 5% of the total assets of the Portfolio (based on
                        current market value at the time of investment) would be
                        invested in the securities of such issuer; provided,
                        however, that the Portfolio may invest up to 25% of its
                        total assets without regard to this restriction of, and
                        as permitted by, Rule 2a-7.
 
                     2. Purchase any securities which would cause more than 25%
                        of the total assets of the Portfolio, based on current
                        value at the time of such purchase, to be invested in
                        the securities of one or more issuers conducting their
                        principal business activities in the same industry,
                        provided that this limitation does not apply to
                        investments in obligations issued or guaranteed by the
                        U.S. Government or its agencies and instrumentalities.
 
                     3. Borrow money except for temporary or emergency purposes,
                        and then only in an amount not exceeding 10% of the
                        value of the total assets of the Portfolio. All
                        borrowings will be repaid before making additional
                        investments and any interest paid on such borrowings
                        will reduce the income of the Portfolio.
 
                     The foregoing percentage limitations will apply at the time
                     of the purchase of a security. Additional fundamental
                     investment limitations are set forth in the Statement of
                     Additional Information.
THE MANAGER
          ______________________________________________________________________
 
                     SEI Fund Management (the "Manager" and the "Transfer
                     Agent") provides the Trust with overall management
                     services, regulatory reporting, all necessary office space,
                     equipment, personnel and facilities, and serves as
                     institutional transfer agent and dividend disbursing agent.
 
                           For these services, the Manager is entitled to a fee,
                     which is calculated daily and paid monthly, at an annual
                     rate of .36% of the average daily net assets of the
                     Portfolio. The Manager has voluntarily agreed to waive a
                     portion of its fee in order to limit the total operating
                     expenses to not more than .83% of the average daily net
                     assets of Class C shares of the Portfolio, on an annualized
                     basis. The Manager reserves the right, in its sole
                     discretion, to terminate this voluntary fee waiver at any
                     time. For the fiscal year ended
 
                                                                               6

                     August 31, 1997, the Portfolio paid management fees, after
                     waivers, of .25% of its average daily net assets.
THE ADVISER
         _______________________________________________________________________
 
                     Weiss, Peck & Greer, L.L.C., serves as the Portfolio's
                     investment adviser under an investment advisory agreement
                     with the Trust (the "Advisory Agreement"). Under the
                     Advisory Agreement, the Adviser invests the assets of the
                     Portfolio, and continuously reviews, supervises and
                     administers the Portfolio's investment program. The Adviser
                     is independent of the Manager and discharges its
                     responsibilities subject to the supervision of, and
                     policies set by, the Trustees of the Trust.
 
                           The Adviser is a limited liability company founded as
                     a limited partnership in 1970, and engages in investment
                     management, venture capital management and management
                     buyouts. The Adviser has been active since its founding in
                     managing portfolios of tax exempt securities. As of
                     September 30, 1997, total assets under management were
                     approximately $14.6 billion. The principal business address
                     of the Adviser is One New York Plaza, New York, New York
                     10004.
 
                           Janet Fiorenza acts as the portfolio manager for the
                     Portfolio. Ms. Fiorenza, a Principal of the Adviser, has
                     been associated with the Adviser's Tax Exempt Fixed Income
                     group since 1988, and with its predecessor since 1980.
 
                           For its services, the Adviser is entitled to a fee,
                     which is calculated daily and paid monthly, at an annual
                     rate of .05% of the combined average daily net assets of
                     the money market portfolios of the Trust that are advised
                     by the Adviser up to $500 million, .04% of such assets from
                     $500 million to $1 billion and .03% of such assets in
                     excess of $1 billion. Such fees are allocated daily among
                     these portfolios based on their relative net assets. For
                     the fiscal year ended August 31, 1997, the Portfolio paid
                     advisory fees, after waivers, of .04% of its relative net
                     assets.
 
DISTRIBUTION AND
SHAREHOLDER
SERVICING
      __________________________________________________________________________
 
                     SEI Investments Distribution Co. (the "Distributor"), a
                     wholly owned subsidiary of SEI Investments Company ("SEI
                     Investments"), serves as the Portfolio's distributor
                     pursuant to a distribution agreement (the "Distribution
                     Agreement") with the Trust.
 
                           The Portfolio has adopted plans under which firms,
                     including the Distributor, that provide shareholder and
                     administrative services may receive compensation therefor.
                     The Class A, B and C plans differ in a number of ways,
                     including the amounts that may be paid. Under each plan,
                     the Distributor may provide those services itself or may
                     enter into arrangements under which third parties provide
                     such services and are compensated by the Distributor. Under
                     such arrangements the Distributor may retain as a profit
                     any difference between the fee it receives and the amount
                     it pays such third parties. In addition, the Portfolio may
                     enter into such arrangements directly.
 
                                                                               7
<PAGE>
                           Under the Class C shareholder service plan, the
                     Distributor is entitled to receive shareholder service fees
                     at an annual rate of up to .25% of average daily net assets
                     in return for the Distributor's (or its agent's) efforts in
                     maintaining client accounts; arranging for bank wires;
                     responding to client inquiries concerning services provided
                     or investment; and assisting clients in changing dividend
                     options, account designations and addresses. In addition,
                     under their administrative services plans, Class C shares
                     will pay the Distributor administrative services fees at
                     specified percentages of the average daily net assets of
                     the shares of the Class (up to .25%). Administrative
                     services include sub-accounting; providing information on
                     share positions to clients; forwarding shareholder
                     communications to clients; processing purchase, exchange
                     and redemption orders and processing divided payments.
 
                           It is possible that an institution may offer
                     different classes of shares to its customers and differing
                     services to the Classes of the Portfolio and thus receive
                     compensation with respect to different classes. These
                     financial institutions may also charge separate fees to
                     their customers.
 
                           The Trust may execute brokerage or other agency
                     transactions through the Distributor for which the
                     Distributor may receive compensation.
 
                           The Distributor may, from time to time and at its own
                     expense, provide promotional incentives, in the form of
                     cash or other compensation, to certain financial
                     institutions whose representatives have sold or are
                     expected to sell significant amounts of the Portfolio's
                     shares.
 
PURCHASE AND
REDEMPTION OF SHARES
    ____________________________________________________________________________
 
                     Financial institutions may acquire shares of the Portfolio
                     for their own account, or as a record owner on behalf of
                     fiduciary, agency or custody accounts, by placing orders
                     with the Transfer Agent (or its authorized agent).
                     Institutions that use certain SEI proprietary systems may
                     place orders electronically through those systems.
                     Financial institutions which purchase shares for the
                     accounts of their customers may impose separate charges on
                     these customers for account services. Financial
                     institutions may impose an earlier cut-off time for receipt
                     of purchase orders directed through them to allow for
                     processing and transmittal of these orders to the Transfer
                     Agent for effectiveness on the same day.
 
                           Shares of the Portfolio may be purchased or redeemed
                     on days on which the New York Stock Exchange is open for
                     business ("Business Days"). However, money market fund
                     shares cannot be purchased by Federal Reserve wire on
                     federal holidays restricting wire transfers.
 
                           Shareholders who desire to purchase shares for cash
                     must place their orders with the Transfer Agent (or its
                     authorized agent) prior to the determination of net asset
                     value and in accordance with the procedures described below
                     for the order to be accepted on
 
                                                                               8
<PAGE>
                     that Business Day. Cash investments must be transmitted or
                     delivered in federal funds to the wire agent by the close
                     of business on the same day the order is placed.
 
                           The Trust reserves the right to reject a purchase
                     order when the Transfer Agent determines that it is not in
                     the best interest of the Trust or shareholders to accept
                     such purchase order.
 
                           The Trust will send shareholders a statement of
                     shares owned after each transaction. The purchase price of
                     shares is the net asset value next determined after a
                     purchase order is received and accepted by the Trust, which
                     is expected to remain constant at $1.00. The net asset
                     value per share of the Portfolio is determined by dividing
                     the total value of its investments and other assets, less
                     any liabilities, by the total number of outstanding shares
                     of the Portfolio. The Portfolio's investments will be
                     valued by the amortized cost method described in the
                     Statement of Additional Information. Net asset value per
                     share is determined daily as of 2:00 p.m., Eastern time, on
                     each Business Day.
 
                           Shareholders who desire to redeem shares of the
                     Portfolio must place their redemption orders with the
                     Transfer Agent (or its authorized agent) prior to 12:30
                     p.m., Eastern time, on any Business Day. Otherwise, the
                     redemption order will be effective on the next Business
                     Day. The redemption price is the net asset value per share
                     of the Portfolio next determined after receipt by the
                     Transfer Agent, and effectiveness, of the redemption order.
                     For redemption orders received before 12:30 p.m., Eastern
                     time, on any Business Day, payment will be made the same
                     day by transfer of federal funds. Otherwise, the redemption
                     will be effective on the next Business Day.
 
                           If a shareholder's aggregate balance is less than $45
                     million as a result of redemption or transfer, for a period
                     of seven consecutive days, the Trust reserves the right to
                     redeem that shareholder's shares in the Portfolio for their
                     current net asset value. Before the Trust redeems such
                     shares, the shareholder will be given notice that the value
                     of its shares is less than the minimum amount, and will be
                     allowed sixty days to make an additional investment in an
                     amount that will increase the value of the account to at
                     least $50 million.
 
                           Purchase and redemption orders may be placed by
                     telephone. Neither the Trust nor the Transfer Agent will be
                     responsible for any loss, liability, cost or expense for
                     acting upon wire instructions or upon telephone
                     instructions that it reasonably believes to be genuine. The
                     Trust and the Transfer Agent will each employ reasonable
                     procedures to confirm that instructions communicated by
                     telephone are genuine, including requiring a form of
                     personal identification prior to acting upon instructions
                     received by telephone and recording telephone instructions.
 
                           If market conditions are extraordinarily active, or
                     other extraordinary circumstances exist, shareholders may
                     experience difficulties placing redemption orders by
                     telephone, and may wish to consider placing orders by other
                     means.
 
                                                                               9

PERFORMANCE
          ______________________________________________________________________
 
                     From time to time the Portfolio advertises its "current
                     yield," "tax equivalent yield" and "effective yield." These
                     figures are based on historical earnings and are not
                     intended to indicate future performance. The "current
                     yield" of the Portfolio refers to the income generated by
                     an investment over a seven-day period which is then
                     "annualized." That is, the amount of income generated by
                     the investment during the 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" (also
                     called "effective compound yield") is calculated similarly
                     but, when annualized, the income earned by an investment is
                     assumed to be reinvested. The "effective yield" will be
                     slightly higher than the "current yield" because of the
                     compounding effect of this assumed reinvestment. The "tax
                     equivalent yield" is calculated by determining the rate of
                     return that would have been achieved on a fully taxable
                     investment to produce the after-tax equivalent of the
                     Portfolio's yield, assuming certain tax brackets for a
                     shareholder.
 
                           The Portfolio may periodically compare its
                     performance to that of: (i) other mutual funds tracked by
                     mutual fund rating services (such as Lipper Analytical),
                     financial and business publications and periodicals; (ii)
                     broad groups of comparable mutual funds; (iii) unmanaged
                     indices which may assume investment of dividends but
                     generally do not reflect deductions for administrative and
                     management costs; or (iv) other investment alternatives.
                     The Portfolio may also quote financial and business
                     publications and periodicals as they relate to fund
                     management, investment philosophy and investment
                     techniques.
 
                           The performance of Class A shares will normally be
                     higher than that of Class B and Class C shares because of
                     the additional administrative services expenses charged to
                     Class B and Class C shares.
TAXES
  ______________________________________________________________________________
 
                     The following summary of federal income tax consequences is
                     based on current tax laws and regulations, which may be
                     changed by legislative, judicial or administrative action.
                     No attempt has been made to present a detailed explanation
                     of the federal income tax treatment of the Portfolio or its
                     shareholders, and state and local tax consequences of an
                     investment in the Portfolio may differ from the federal
                     income tax consequences described below. Accordingly,
                     shareholders are urged to consult their tax advisers
                     regarding specific questions as to federal, state and local
                     income taxes. Additional information concerning taxes is
                     set forth in the Statement of Additional Information.
TAX STATUS OF THE
PORTFOLIO
                     The Portfolio is treated as a separate entity for federal
                     income tax purposes and is not combined with the Trust's
                     other portfolios. The Portfolio intends to continue to
                     qualify for the special tax treatment afforded regulated
                     investment companies under Subchapter M of the Internal
                     Revenue Code of 1986, as amended (the "Code"), so as to be
                     relieved of
 
                                                                              10
<PAGE>
                     federal income tax on net investment company taxable income
                     and net capital gain (the excess of net long-term capital
                     gain over net short-term capital loss) distributed to
                     shareholders.
TAX STATUS OF
DISTRIBUTIONS
                     The Portfolio intends to distribute substantially all of
                     its net investment income (including net short-term capital
                     gain) to shareholders. If, at the close of each quarter of
                     its taxable year, at least 50% of the value of the
                     Portfolio's total assets consists of obligations the
                     interest on which is excludable from gross income, the
                     Portfolio may pay "exempt-interest dividends" to its
                     shareholders. Exempt-interest dividends are excludable from
                     a shareholder's gross income for federal income tax
                     purposes but may have certain collateral federal tax
                     consequences including alternative minimum tax
                     consequences. In addition, the receipt of exempt-interest
                     dividends may cause persons receiving Social Security or
                     Railroad Retirement benefits to be taxable on a portion of
                     such benefits. See the Statement of Additional Information.
 
                           Any dividends paid out of income realized by the
                     Portfolio on taxable securities will be taxable to
                     shareholders as ordinary income (whether received in cash
                     or in additional shares) to the extent of the Portfolio's
                     earnings and profits and will not qualify for the
                     dividends-received deduction for corporate shareholders.
                     Distributions to shareholders of net capital gains of the
                     Portfolio also will not qualify for the dividends received
                     deduction and will be taxable to shareholders as long-term
                     capital gain, whether received in cash or additional
                     shares, and regardless of how long a shareholder has held
                     the shares.
 
                           Dividends declared by the Portfolio in October,
                     November or December of any year and payable to
                     shareholders of record on a date in any such month will be
                     deemed to have been paid by the Portfolio and received by
                     the shareholders on December 31 of that year if paid by the
                     Portfolio at any time during the following January. The
                     Portfolio intends to make sufficient distributions prior to
                     the end of each calendar year to avoid liability for the
                     federal excise tax applicable to regulated investment
                     companies.
 
                           Interest on indebtedness incurred or continued by a
                     shareholder in order to purchase or carry shares of the
                     Portfolio is not deductible for federal income tax purposes
                     to the extent that it relates to exempt-interest dividends
                     distributed to the shareholder during the taxable year.
                     Furthermore, the Portfolio may not be an appropriate
                     investment for persons (including corporations and other
                     business entities) who are "substantial users" (or persons
                     related to "substantial users") of facilities financed by
                     industrial development bonds or private activity bonds.
                     Such persons should consult their tax advisers before
                     purchasing shares.
 
                           The Portfolio will report annually to its
                     shareholders the portion of dividends that is taxable and
                     the portion that is tax-exempt based on income received by
                     the Portfolio during the year to which the dividends
                     relate.
 
                           Each sale, exchange, or redemption of the Portfolio's
                     shares is a taxable transaction to the shareholder.
 
                                                                              11

GENERAL INFORMATION
         _______________________________________________________________________
THE TRUST
                     The Trust was organized as a Massachusetts business trust
                     under a Declaration of Trust dated March 15, 1982. The
                     Declaration of Trust permits the Trust to offer separate
                     portfolios of shares and different classes of each
                     portfolio. In addition to the Portfolio, the Trust consists
                     of the following portfolios: Tax Free Portfolio, California
                     Tax Exempt Portfolio, Intermediate-Term Municipal
                     Portfolio, Pennsylvania Municipal Portfolio, New York
                     Intermediate-Term Municipal Portfolio, and Pennsylvania Tax
                     Free Portfolio. All consideration received by the Trust for
                     shares of any portfolio and all assets of such portfolio
                     belong to that portfolio and would be subject to
                     liabilities related thereto.
 
                           The Trust pay its expenses, including fees of its
                     service providers, audit and legal expenses, expenses of
                     preparing prospectuses, proxy solicitation materials and
                     reports to shareholders, costs of custodial services and
                     registering the shares under federal and state securities
                     laws, pricing, insurance expenses, litigation and other
                     extraordinary expenses, brokerage costs, interest charges,
                     taxes and organization expenses.
TRUSTEES OF THE TRUST
                     The management and affairs of the Trust are supervised by
                     the Trustees under the laws of the Commonwealth of
                     Massachusetts. The Trustees have approved contracts under
                     which, as described above, certain companies provide
                     essential services to the Trust.
VOTING RIGHTS
                     Each share held entitles the shareholder of record to one
                     vote. The shareholders of each portfolio or class will vote
                     separately on matters relating solely to that Portfolio or
                     class, such as any distribution plan. As a Massachusetts
                     business trust, the Trust is not required to hold annual
                     meetings of shareholders, but approval will be sought for
                     certain changes in the operation of the Trust and for the
                     election of Trustees under certain circumstances. In
                     addition, a Trustee may be removed by the remaining
                     Trustees or by shareholders at a special meeting called
                     upon written request of shareholders owning at least 10% of
                     the outstanding shares of the Trust. In the event that such
                     a meeting is requested, the Trust will provide appropriate
                     assistance and information to the shareholders requesting
                     the meeting.
REPORTING
                     The Trust issues unaudited financial statements
                     semi-annually and audited financial statements annually.
                     The Trust furnishes proxy statements and other reports to
                     shareholders of record.
SHAREHOLDER INQUIRIES
                     Shareholder inquiries should be directed to the Manager.
                     SEI Fund Management, Oaks, Pennsylvania, 19456.
DIVIDENDS
                     The net investment income (exclusive of capital gains) of
                     the Portfolio is determined and declared on each Business
                     Day as a dividend for shareholders of record as of the
                     close of business on that day. Dividends are paid by the
                     Portfolio in federal funds or in additional shares at the
                     discretion of the shareholder on the first Business Day of
                     each month. Dividends will be paid on the next Business Day
                     to shareholders who redeem all of their
 
                                                                              12
<PAGE>
                     shares of the Portfolio at any time during the month.
                     Currently, capital gains, if any, are distributed at the
                     end of the calendar year.
 
                           Shareholders automatically receive all income
                     dividends and capital gain distributions in additional
                     shares, unless the shareholder has elected to take such
                     payment in cash. Shareholders may change their election by
                     providing written notice to the Manager at least 15 days
                     prior to the distribution.
 
                           The dividends on Class A shares of the Portfolio are
                     normally higher than those on Class B and Class C shares
                     because of the additional administrative services expenses
                     charged to Class B and Class C shares.

DESCRIPTION OF
PERMITTED
INVESTMENTS AND RISK
FACTORS   ______________________________________________________________________
 
                     The following is a description of certain of the permitted
                     investments for the Portfolio, and the associated risk
                     factors:
MONEY MARKET SECURITIES
                     Money market securities are high-quality,
                     dollar-denominated, short-term debt instruments. They
                     consist of: (i) bankers' acceptances, certificates of
                     deposits, notes and time deposits of highly-rated U.S.
                     banks; (ii) U.S. Treasury obligations and obligations
                     issued by the agencies and instrumentalities of the U.S.
                     Government; and (iii) repurchase agreements involving any
                     of the foregoing obligations entered into with highly-rated
                     banks and broker-dealers.
MUNICIPAL SECURITIES
                     Municipal Securities consist of (i) debt obligations issued
                     by or on behalf of public authorities to obtain funds to be
                     used for various public facilities, for refunding
                     outstanding obligations, for general operating expenses and
                     for lending such funds to other public institutions and
                     facilities, and (ii) certain private activity and
                     industrial development bonds issued by or on behalf of
                     public authorities to obtain funds to provide for the
                     construction, equipment, repair or improvement of privately
                     operated facilities.
 
                           General obligation bonds are backed by the taxing
                     power of the issuing municipality. Revenue bonds are backed
                     by the revenues of a project or facility, tolls from a toll
                     bridge, for example. Certificates of participation
                     represent an interest in an underlying obligation or
                     commitment such as an obligation issued in connection with
                     a leasing arrangement. The payment of principal and
                     interest on private activity and industrial
 
                                                                              13
<PAGE>
                     development bonds generally is dependent solely on the
                     ability of the facility's user to meet its financial
                     obligations and the pledge, if any, of real and personal
                     property so financed as security for such payment.
 
                           Municipal notes include general obligation notes, tax
                     anticipation notes, revenue anticipation notes, bond
                     anticipation notes, certificates of indebtedness, demand
                     notes and construction loan notes and participation
                     interests in municipal notes. Municipal bonds include
                     general obligation bonds, revenue or special obligation
                     bonds, private activity and industrial development bonds
                     and participation interests in municipal bonds.
REPURCHASE AGREEMENTS
                     Repurchase agreements are arrangements by which a Portfolio
                     obtains a security and simultaneously commits to return the
                     security to the seller at an agreed upon price (including
                     principal and interest) on an agreed upon date within a
                     number of days from the date of purchase. Repurchase
                     agreements are considered loans under the 1940 Act.
STANDBY COMMITMENTS AND
PUTS
                     Securities subject to standby commitments or puts permit
                     the holder thereof to sell the securities at a fixed price
                     prior to maturity. Securities subject to a standby
                     commitment or put may be sold at any time at the current
                     market price. However, unless the standby commitment or put
                     was an integral part of the security as originally issued,
                     it may not be marketable or assignable; therefore, the
                     standby commitment or put would only have value to the
                     Portfolio owning the security to which it relates. In
                     certain cases, a premium may be paid for a standby
                     commitment or put, which premium will have the effect of
                     reducing the yield otherwise payable on the underlying
                     security. The Portfolio will limit standby commitment or
                     put transactions to institutions believed to present
                     minimal credit risks.
U.S. GOVERNMENT
OBLIGATIONS
                     Obligations issued by the U.S. Treasury or issued or
                     guaranteed by agencies of the U.S. Government and
                     obligations issued or guaranteed by instrumentalities of
                     the U.S. Government. Some of these securities are supported
                     by the full faith and credit of the U.S. Treasury (E.G.,
                     Government National Mortgage Association securities),
                     others are supported by the right of the issuer to borrow
                     from the Treasury (E.G., Federal Farm Credit Bank
                     securities), while still others are supported only by the
                     credit of the instrumentality (E.G., Fannie Mae
                     securities).
VARIABLE AND FLOATING
RATE INSTRUMENTS
                     Certain of the obligations purchased by the Portfolio may
                     carry variable or floating rates of interest and may
                     involve a conditional or unconditional demand feature. Such
                     obligations may include variable amount master demand
                     notes. Such instruments bear interest at rates which are
                     not fixed, but which vary with changes in specified market
                     rates or indices. The interest rates on these securities
                     may be reset daily, weekly, quarterly or at some other
                     interval, and may have a floor or ceiling on interest rate
                     changes. There is a risk that the current interest rate on
                     such obligations may not accurately reflect existing market
                     interest rates. A demand instrument with a demand notice
                     period exceeding seven days may be considered illiquid if
                     there is no secondary market for such security.
 
                                                                              14

WHEN-ISSUED AND DELAYED
DELIVERY SECURITIES
                     When-issued or delayed delivery transactions involve the
                     purchase of an instrument with payment and delivery taking
                     place in the future. Delivery of and payment for these
                     securities may occur a month or more after the date of the
                     purchase commitment. The Portfolio will maintain with the
                     custodian a separate account with liquid securities or cash
                     in an amount at least equal to these commitments. The
                     interest rate realized on these securities is fixed as of
                     the purchase date, and no interest accrues to the Portfolio
                     before settlement.
 
                                                                              15

This Prospectus sets forth concisely information about the above-referenced
Portfolio that an investor needs to know before investing. Please read this
Prospectus carefully, and keep it on file for future reference.
 
A Statement of Additional Information dated December 31, 1997, has been filed

Additional Information is incorporated into this Prospectus by reference.
 
SEI Tax Exempt Trust (the "Trust") is an open-end investment management company,
certain classes of which offer financial institutions a convenient means of
investing their own funds, or funds for which they act in a fiduciary, agency or
custodial capacity, in one or more professionally managed diversified and
non-diversified portfolios of securities. A portfolio may offer separate classes
of shares that differ from each other primarily in the allocation of certain
expenses and minimum investment amounts. This Prospectus offers Class A shares
of the Trust's Tax Free Portfolio (the "Portfolio"), a money market portfolio.
 
AN INVESTMENT IN THE PORTFOLIO IS NEITHER INSURED NOR GUARANTEED BY THE U.S.
GOVERNMENT, AND THERE CAN BE NO ASSURANCE THAT THE PORTFOLIO WILL BE ABLE TO
MAINTAIN A STABLE NET ASSET VALUE OF $1.00 PER SHARE.
 
- --------------------------------------------------------------------------------
 
 THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
 EXCHANGE COMMISSION, NOR HAS THE SECURITIES AND EXCHANGE COMMISSION PASSED
 UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE
 CONTRARY IS A CRIMINAL OFFENSE.
 
 THE TRUST'S SHARES ARE NOT DEPOSITS OR OBLIGATIONS OF, OR GUARANTEED OR
 ENDORSED BY, ANY BANK. THE SHARES ARE NOT FEDERALLY INSURED BY THE FEDERAL
 DEPOSIT INSURANCE CORPORATION, THE FEDERAL RESERVE BOARD OR ANY OTHER
 GOVERNMENT AGENCY. INVESTMENT IN THE SHARES INVOLVES RISK, INCLUDING POSSIBLE

INVESTMENT OBJECTIVE
AND POLICIES
     ___________________________________________________________________________
 
                     The Portfolio's investment objective is to preserve
                     principal value and maintain a high degree of liquidity
                     while providing current income exempt from federal income
                     taxes. There can be no assurance that the Portfolio will
                     meet its investment objective.
 
                           The Portfolio invests in U.S. dollar denominated
                     municipal securities of issuers located in all fifty
                     states, the District of Columbia, Puerto Rico and other
                     U.S. territories and possessions (collectively, "Municipal
                     Securities"). At least 80% of the Portfolio's net assets
                     will be invested in securities the interest on which is
                     exempt from federal income taxes, based on opinions from
                     bond counsel for the issuers. This investment policy is a
                     fundamental policy of the Portfolio. Under normal
                     conditions, the Portfolio will invest at least 80% of its
                     net assets in securities the interest on which is not a
                     preference item for purposes of the federal alternative
                     minimum tax.
 
                           The Portfolio may purchase municipal bonds, municipal
                     notes and tax-exempt commercial paper, but only if such
                     securities, at the time of purchase, meet the quality,
                     maturity and diversification requirements imposed by Rule
                     2a-7. See "General Investment Policies."
 
                           The Adviser will not invest more than 25% of
                     Portfolio assets in Municipal Securities (a) whose issuers
                     are located in the same state or (b) the interest on which
                     is derived from revenues of similar type projects. This
                     restriction does not apply to Municipal Securities in any
                     of the following categories: public housing authorities;
                     general obligations of states and localities; state and
                     local housing finance authorities or municipal utilities
                     systems.
 
                           There could be economic, business, or political
                     developments which might affect all Municipal Securities of
                     a similar type. To the extent that a significant portion of
                     the Portfolio's assets are invested in Municipal Securities
                     payable from revenues on similar projects, the Portfolio
                     will be subject to the peculiar risks presented by such
                     projects to a greater extent than it would be if the
                     Portfolio's assets were not so invested. Moreover, in
                     seeking to attain its investment objective the Portfolio
                     may invest all or any part of its assets in Municipal
                     Securities that are industrial development bonds.
 
                                                                               4

GENERAL INVESTMENT
POLICIES
     ___________________________________________________________________________
 
                     In purchasing obligations, the Portfolio complies with the
                     requirements of Rule 2a-7 under the Investment Company Act
                     of 1940 (the "1940 Act"), as that Rule may be amended from
                     time to time. These requirements currently provide that the
                     Portfolio must limit its investments to securities with
                     remaining maturities of 397 days or less, and must maintain
                     a dollar-weighted average maturity of 90 days or less. In
                     addition, the Portfolio may only invest in eligible
                     securities. In general, this means securities rated in one
                     of the two highest categories for short-term securities by
                     at least two nationally recognized statistical rating
                     organizations ("NRSROs") (or by one NRSRO if only one NRSRO
                     has rated the security), or, if unrated, determined by
                     Weiss, Peck & Greer, L.L.C. (the "Adviser") to be of
                     equivalent quality. Since the Portfolio often purchases
                     securities supported by credit enhancements from banks and
                     other financial institutions, changes in the credit quality
                     of these institutions could cause losses to the Portfolio
                     and affect its share price.
 
                           Securities rated in the highest rating category
                     (E.G., A-1 by Standard & Poor's Corporation ("S&P")) by at
                     least two NRSROs (or, if unrated, determined by the Adviser
                     to be of comparable quality) are "first tier" securities.
                     Non-first tier securities rated in the second highest
                     rating category (E.G., A-2 by S&P) by at least one NRSRO
                     (or, if unrated, determined by the Adviser to be of
                     comparable quality) are considered to be "second tier"
                     securities. The Portfolio's investments in non-first tier
                     conduit securities will be limited to 5% of the Portfolio's
                     assets. Conduit securities are securities issued to finance
                     non-governmental private projects, such as housing
                     developments and retirement homes, and for which the
                     ultimate obligor is not a governmental issuer.
 
                           The Portfolio may invest in variable and floating
                     rate obligations, may purchase securities on a
                     "when-issued" basis, and reserves the right to engage in
                     transactions involving standby commitments. While the
                     Portfolio generally intends to be fully invested in
                     federally tax-exempt securities, the Portfolio may invest
                     up to 20% of its net assets in taxable money market
                     instruments and securities the interest on which is a
                     preference item for purposes of the alternative minimum
                     tax. The Portfolio will not invest more than 10% of its net
                     assets in illiquid securities.
 
                           For a description of the permitted investments and
                     ratings, see the "Description of Permitted Investments and
                     Risk Factors" and the Statement of Additional Information.
 
INVESTMENT
LIMITATIONS
        ________________________________________________________________________
 
                     The investment objective and investment limitations are
                     fundamental policies of the Portfolio. Fundamental policies
                     cannot be changed with respect to the Trust or the
                     Portfolio without the consent of the holders of a majority
                     of the Trust's or the Portfolio's
 
                                                                               5
<PAGE>
                     outstanding shares. It is a fundamental policy of the
                     Portfolio to use its best efforts to maintain a constant
                     net asset value of $1.00 per share.
 
                     THE PORTFOLIO MAY NOT:
 
                     1. Purchase securities of any issuer (except securities
                        issued or guaranteed by the United States Government,
                        its agencies or instrumentalities) if, as a result, more
                        than 5% of the total assets of the Portfolio (based on
                        current market value at the time of investment) would be
                        invested in the securities of such issuer; provided,
                        however, that the Portfolio may invest up to 25% of its
                        total assets without regard to this restriction of, and
                        as permitted by, Rule 2a-7.
 
                     2. Purchase any securities which would cause more than 25%
                        of the total assets of the Portfolio, based on current
                        value at the time of such purchase, to be invested in
                        the securities of one or more issuers conducting their
                        principal business activities in the same industry,
                        provided that this limitation does not apply to
                        investments in obligations issued or guaranteed by the
                        U.S. Government or its agencies and instrumentalities.
 
                     3. Borrow money except for temporary or emergency purposes,
                        and then only in an amount not exceeding 10% of the
                        value of the total assets of the Portfolio. All
                        borrowings will be repaid before making additional
                        investments and any interest paid on such borrowings
                        will reduce the income of the Portfolio.
 
                     The foregoing percentage limitations will apply at the time
                     of the purchase of a security. Additional investment
                     limitations are set forth in the Statement of Additional
                     Information.
THE MANAGER
          ______________________________________________________________________
 
                     SEI Fund Management (the "Manager" and the "Transfer
                     Agent") provides the Trust with overall management
                     services, regulatory reporting, all necessary office space,
                     equipment, personnel and facilities, and serves as
                     institutional transfer agent and dividend disbursing agent.
 
                           For these services, the Manager is entitled to a fee,
                     which is calculated daily and paid monthly, at an annual
                     rate of .36% of the average daily net assets of the
                     Portfolio. The Manager has voluntarily agreed to waive a
                     portion of its fee in order to limit the total operating
                     expenses of the Class A shares of the Portfolio to not more
                     than .45% of the Portfolio's average daily net assets
                     attributable to Class A shares, on an annualized basis. The
                     Manager reserves the right, in its sole discretion, to
                     terminate this voluntary fee waiver at any time. For the
                     fiscal year ended August 31, 1997, the Portfolio paid
                     management fees, after waivers, of .36% of its average
                     daily net assets.
THE ADVISER
         _______________________________________________________________________
 
                     Weiss, Peck & Greer, L.L.C., acts as the Portfolio's
                     investment adviser under an investment advisory agreement
                     with the Trust (the "Advisory Agreement"). Under the
                     Advisory Agreement, the Adviser invests the assets of the
                     Portfolio, and continuously reviews,
 
                                                                               6
<PAGE>
                     supervises and administers the Portfolio's investment
                     program. The Adviser is independent of the Manager and SEI
                     Investments, and discharges its responsibilities subject to
                     the supervision of, and policies set by, the Trustees of
                     the Trust.
 
                           The Adviser is a limited liability company founded as
                     a limited partnership in 1970, and engages in investment
                     management, venture capital management and management
                     buyouts. The Adviser has been active since its founding in
                     managing portfolios of tax exempt securities. As of
                     September 30, 1997, total assets under management were
                     approximately $14.6 billion. The principal business address
                     of the Adviser is One New York Plaza, New York, New York
                     10004.
 
                           Janet Fiorenza acts as the portfolio manager for the
                     Portfolio. Ms. Fiorenza, a Principal of the Adviser, has
                     been associated with the Adviser's Tax Exempt Fixed Income
                     group since 1988, and with its predecessor since 1980.
 
                           For its services, the Adviser is entitled to a fee,
                     which is calculated daily and paid monthly, at an annual
                     rate of .05% of the combined average daily net assets of
                     the money market portfolios of the Trust that are advised
                     by the Adviser up to $500 million, .04% of such assets from
                     $500 million to $1 billion, and .03% of such assets in
                     excess of $1 billion. Such fees are allocated daily among
                     these portfolios based on their relative net assets. For
                     the fiscal year ended August 31, 1997, the Portfolio paid
                     advisory fees, after waivers, of .04% of its relative daily
                     net assets.

                     share positions to clients; forwarding shareholder
                     communications to clients; processing purchase, exchange
                     and redemption orders; and processing dividend payments.
                     Under the Service Plan, the Distributor may retain as a
                     profit any difference between the fee it receives and the
                     amount it pays to third parties.
 
                                                                               7

                           It is possible that an institution may offer
                     different classes of shares to its customers and thus
                     receive different compensation with respect to different
                     classes. These financial institutions may also charge
                     separate fees to their customers.
 
                           The Trust may also execute brokerage or other agency
                     transactions through the Distributor for which the
                     Distributor may receive usual and customary compensation.
 
                           The Distributor may, from time to time and at its own
                     expense, provide promotional incentives, in the form of
                     cash or other compensation, to certain financial
                     institutions whose representatives have sold or are
                     expected to sell significant amounts of the Portfolio's
                     shares.
 
PURCHASE AND
REDEMPTION OF SHARES
    ____________________________________________________________________________
 
                     Financial institutions may acquire shares of the Portfolio
                     for their own account, or as a record owner on behalf of
                     fiduciary, agency or custody accounts, by placing orders
                     with the Transfer Agent (or its authorized agent).
                     Institutions that use certain SEI proprietary systems may
                     place orders electronically through those systems.
                     Financial institutions which purchase shares for the
                     accounts of their customers may impose separate charges on
                     these customers for account services. Financial
                     institutions may impose an earlier cut-off time for receipt
                     of purchase orders directed through them to allow for
                     processing and transmittal of these orders to the Transfer
                     Agent for effectiveness on the same day.
 
                           Shares of the Portfolio may be purchased or redeemed
                     on days on which the New York Stock Exchange is open for
                     business ("Business Days"). However, money market fund
                     shares cannot be purchased by Federal Reserve wire on
                     federal holidays restricting wire transfers.
 
                           Shareholders who desire to purchase shares for cash
                     must place their orders with the Transfer Agent (or its
                     authorized agent) prior to the determination of net asset
                     value and in accordance with the procedures described below
                     for the order to be accepted on that Business Day. Cash
                     investments must be transmitted or delivered in federal
                     funds to the wire agent by the close of business on the
                     same day the order is placed. The Trust reserves the right
                     to reject a purchase order when the Distributor determines
                     that it is not in the best interest of the Trust or
                     shareholders to accept such purchase order.
 
                           The Trust will send shareholders a statement of
                     shares owned after each transaction. The purchase price of
                     shares is the net asset value next determined after a
                     purchase order is received and accepted by the Trust, which
                     is expected to remain constant at $1.00. The net asset
                     value per share of the Portfolio is determined by dividing
                     the total value of its investments and other assets, less
                     any liabilities, by the total number of outstanding shares
                     of the Portfolio. The Portfolio's investments will be
                     valued by the amortized cost method described in the
                     Statement of Additional Information. Net asset value per
                     share is determined daily as of 2:00 p.m., Eastern time, on
                     each Business Day.
 
                                                                               8

                           Shareholders who desire to redeem shares of the
                     Portfolio must place their redemption orders with the
                     Transfer Agent (or its authorized agent) prior to 12:30
                     p.m., Eastern time, on any Business Day. Otherwise, the
                     redemption order will be effective on the next Business
                     Day. The redemption price is the net asset value per share
                     of the Portfolio next determined after receipt by the
                     Transfer Agent, and effectiveness, of the redemption order.
                     For redemption orders received before 12:30 p.m., Eastern
                     time, on any Business Day, payment will be made the same
                     day by transfer of federal funds. Otherwise, the redemption
                     order will be effective on the next Business Day.
 
                           Purchase and redemption orders may be placed by
                     telephone. Neither the Trust nor the Transfer Agent will be
                     responsible for any loss, liability, cost or expense for
                     acting upon wire instructions or upon telephone
                     instructions that it reasonably believes to be genuine. The
                     Trust and the Transfer Agent will each employ reasonable
                     procedures to confirm that instructions communicated by
                     telephone are genuine, including requiring a form of
                     personal identification prior to acting upon instructions
                     received by telephone and recording telephone instructions.
 
                           If market conditions are extraordinarily active, or
                     other extraordinary circumstances exist, shareholders may
                     experience difficulties placing redemption orders by
                     telephone, and may wish to consider placing orders by other
                     means.
PERFORMANCE
          ______________________________________________________________________
 
                     From time to time the Portfolio advertises its "current
                     yield", "tax equivalent yield" and "effective yield." These
                     figures are based on historical earnings and are not
                     intended to indicate future performance. The "current
                     yield" of the Portfolio refers to the income generated by
                     an investment over a seven-day period which is then
                     "annualized." That is, the amount of income generated by
                     the investment during the 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" (also
                     called "effective compound yield") is calculated similarly
                     but, when annualized, the income earned by an investment is
                     assumed to be reinvested. The "effective yield" will be
                     slightly higher than the "current yield" because of the
                     compounding effect of this assumed reinvestment. The "tax
                     equivalent yield" is calculated by determining the rate of
                     return that would have been achieved on a fully taxable
                     investment to produce the after-tax equivalent of the
                     Portfolio's yield, assuming certain tax brackets for a
                     shareholder.
 
                           The Portfolio may periodically compare its
                     performance to that of: (i) other mutual funds tracked by
                     mutual fund rating services (such as Lipper Analytical),
                     financial and business publications and periodicals; (ii)
                     broad groups of comparable mutual funds; (iii) unmanaged
                     indices which may assume investment of dividends but
                     generally do not reflect deductions for administrative and
                     management costs; or (iv) other investment alternatives.
                     The Portfolio may also quote financial and business
                     publications and
 
                                                                               9
<PAGE>
                     periodicals as they relate to fund management, investment
                     philosophy and investment techniques.
 
                           The performance of Class A shares will normally be
                     higher than that of the Class D shares of the Portfolio
                     because of the additional distribution and transfer agent
                     expenses charged to Class D shares.
TAXES
  ______________________________________________________________________________
 
                     The following summary of federal income tax consequences is
                     based on current tax laws and regulations, which may be
                     changed by legislative, judicial or administrative action.
                     No attempt has been made to present a detailed explanation
                     of the federal income tax treatment of the Portfolio or its
                     shareholders, and state and local tax consequences of an
                     investment in the Portfolio may differ from the federal
                     income tax consequences described below. Accordingly,
                     shareholders are urged to consult their tax advisers
                     regarding specific questions as to federal, state and local
                     income taxes. Additional information concerning taxes is
                     set forth in the Statement of Additional Information.
TAX STATUS OF THE
PORTFOLIO
                     The Portfolio is treated as a separate entity for federal
                     income tax purposes and is not combined with the Trust's
                     other portfolios. The Portfolio intends to continue to
                     qualify for the special tax treatment afforded regulated
                     investment companies under Subchapter M of the Internal
                     Revenue Code of 1986, as amended (the "Code"), so as to be
                     relieved of federal income tax on net investment company
                     taxable income and net capital gain (the excess of net
                     long-term capital gain over net short-term capital loss)
                     distributed to shareholders.
TAX STATUS OF
DISTRIBUTIONS
                     The Portfolio intends to distribute substantially all of
                     its net investment income (including net short-term capital
                     gain) to shareholders. If, at the close of each quarter of
                     its taxable year, at least 50% of the value of the
                     Portfolio's total assets consists of obligations the
                     interest on which is excludable from gross income, the
                     Portfolio may pay "exempt-interest dividends" to its
                     shareholders. Exempt-interest dividends are excludable from
                     a shareholder's gross income for federal income tax
                     purposes but may have certain collateral federal tax
                     consequences including alternative minimum tax
                     consequences. In addition, the receipt of exempt-interest
                     dividends may cause persons receiving Social Security or
                     Railroad Retirement benefits to be taxable on a portion of
                     such benefits. See the Statement of Additional Information.
 
                           Any dividends paid out of income realized by the
                     Portfolio on taxable securities will be taxable to
                     shareholders as ordinary income (whether received in cash
                     or in additional shares) to the extent of the Portfolio's
                     earnings and profits and will not qualify for the
                     dividends-received deduction for corporate shareholders.
                     Distributions to shareholders of net capital gains of the
                     Portfolio also will not qualify for the dividends received
                     deduction and will be taxable to shareholders as long-term
                     capital gain, whether received in cash or additional
                     shares, and regardless of how long a shareholder has held
                     the shares.
 
                                                                              10
<PAGE>
                           Dividends declared by the Portfolio in October,
                     November or December of any year and payable to
                     shareholders of record on a date in any such month will be
                     deemed to have been paid by the Portfolio and received by
                     the shareholders on December 31 of that year if paid by the
                     Portfolio at any time during the following January. The
                     Portfolio intends to make sufficient distributions prior to
                     the end of each calendar year to avoid liability for the
                     federal excise tax applicable to regulated investment
                     companies.
 
                           Interest on indebtedness incurred or continued by a
                     shareholder in order to purchase or carry shares of the
                     Portfolio is not deductible for federal income tax purposes
                     to the extent that it relates to exempt-interest dividends
                     distributed to the shareholder during the taxable year.
                     Furthermore, the Portfolio may not be an appropriate
                     investment for persons (including corporations and other
                     business entities) who are "substantial users" (or persons
                     related to "substantial users") of facilities financed by
                     industrial development bonds or private activity bonds.
                     Such persons should consult their tax advisers before
                     purchasing shares.
 
                           The Portfolio will report annually to its
                     shareholders the portion of dividends that is taxable and
                     the portion that is tax-exempt based on income received by
                     the Portfolio during the year to which the dividends
                     relate.
 
                           Each sale, exchange or redemption of the Portfolio's
                     shares is a taxable transaction for the shareholder.
 
GENERAL INFORMATION
         _______________________________________________________________________
THE TRUST
                     The Trust was organized as a Massachusetts business trust
                     under a Declaration of Trust dated March 15, 1982. The
                     Declaration of Trust permits the Trust to offer separate
                     portfolios of shares and different classes of each
                     portfolio. In addition to the Portfolio, the Trust consists
                     of the following portfolios: Institutional Tax Free
                     Portfolio, California Tax Exempt Portfolio,
                     Intermediate-Term Municipal Portfolio, Pennsylvania
                     Municipal Portfolio, New York Intermediate-Term Municipal
                     Portfolio, and Pennsylvania Tax Free Portfolio. All
                     consideration received by the Trust for shares of any
                     portfolio and all assets of such portfolio belong to that
                     portfolio and would be subject to liabilities related
                     thereto.
 
                           The Trust pays its expenses, including fees of its
                     service providers, audit and legal expenses, expenses of
                     preparing prospectuses, proxy solicitation materials and
                     reports to shareholders, costs of custodial services and
                     registering the shares under federal and state securities
                     laws, pricing, insurance expenses, litigation and other
                     extraordinary expenses, brokerage costs, interest charges,
                     taxes and organization expenses.
TRUSTEES OF THE TRUST
                     The management and affairs of the Trust are supervised by
                     the Trustees under the laws of the Commonwealth of
                     Massachusetts. The Trustees have approved contracts under
                     which, as described above, certain companies provide
                     essential services to the Trust.
VOTING RIGHTS
                     Each share held entitles the shareholder of record to one
                     vote. The shareholders of each portfolio or class will vote
                     separately on matters relating solely to that portfolio or
                     class,
 
                                                                              11
<PAGE>
                     such as any distribution plan. As a Massachusetts business
                     trust, the Trust is not required to hold annual meetings of
                     shareholders but approval will be sought for certain
                     changes in the operation of the Trust and for the election
                     of Trustees under certain circumstances. In addition, a
                     Trustee may be removed by the remaining Trustees or by
                     shareholders at a special meeting called upon written
                     request of shareholders owning at least 10% of the
                     outstanding shares of the Trust. In the event that such a
                     meeting is requested, the Trust will provide appropriate
                     assistance and information to the shareholders requesting
                     the meeting.
REPORTING
                     The Trust issues unaudited financial statements
                     semi-annually and audited financial statements annually.
                     The Trust furnishes proxy statements and other reports to
                     shareholders of record.
SHAREHOLDER INQUIRIES
                     Shareholder inquiries should be directed to the Manager.
                     SEI Fund Management, Oaks, Pennsylvania, 19456.
DIVIDENDS
                     The net investment income (exclusive of capital gains) of
                     the Portfolio is determined and declared on each Business
                     Day as a dividend for shareholders of record as of the
                     close of business on that day. Dividends are paid by the
                     Portfolio in federal funds or in additional shares at the
                     discretion of the shareholder on the first Business Day of
                     each month. Dividends will be paid on the next Business Day
                     to shareholders who redeem all of their shares of the
                     Portfolio at any time during the month. Currently, capital
                     gains, if any, are distributed at the end of the calendar
                     year.
 
                           Shareholders automatically receive all income
                     dividends and capital gain distributions in additional
                     shares, unless the shareholder has elected to take such
                     payment in cash. Shareholders may change their election by
                     providing written notice to the Manager at least 15 days
                     prior to the distribution.
 
                           The dividends on Class A shares of the Portfolio are
                     normally higher than those on Class D shares because of the
                     additional distribution and transfer agent expenses charged
                     to Class D shares.

                     accountants of the Trust.

DESCRIPTION OF
PERMITTED
INVESTMENTS AND RISK
FACTORS   ______________________________________________________________________
 
                     The following is a description of certain of the permitted
                     investments for the Portfolio, and the associated risk
                     factors:
MONEY MARKET SECURITIES
                     Money market securities are high-quality,
                     dollar-denominated, short-term debt instruments. They
                     consist of: (i) bankers' acceptances, certificates of
                     deposits, notes and time deposits of highly-rated U.S.
                     banks; (ii) U.S. Treasury obligations and obligations
                     issued by the agencies and instrumentalities of the U.S.
                     Government; and (iii) repurchase agreements involving any
                     of the foregoing obligations entered into with highly-rated
                     banks and broker-dealers.
MUNICIPAL SECURITIES
                     Municipal Securities consist of (i) debt obligations issued
                     by or on behalf of public authorities to obtain funds to be
                     used for various public facilities, for refunding
                     outstanding obligations, for general operating expenses and
                     for lending such funds to other public institutions and
                     facilities, and (ii) certain private activity and
                     industrial development bonds issued by or on behalf of
                     public authorities to obtain funds to provide for the
                     construction, equipment, repair or improvement of privately
                     operated facilities.
 
                           General obligation bonds are backed by the taxing
                     power of the issuing municipality. Revenue bonds are backed
                     by the revenues of a project or facility, tolls from a toll
                     bridge, for example. Certificates of participation
                     represent an interest in an underlying obligation or
                     commitment such as an obligation issued in connection with
                     a leasing arrangement. The payment of principal and
                     interest on private activity and industrial development
                     bonds generally is dependent solely on the ability of the
                     facility's user to meet its financial obligations and the
                     pledge, if any, of real and personal property so financed
                     as security for such payment.
 
                           Municipal notes include general obligation notes, tax
                     anticipation notes, revenue anticipation notes, bond
                     anticipation notes, certificates of indebtedness, demand
                     notes and construction loan notes and participation
                     interests in municipal notes. Municipal bonds include
                     general obligation bonds, revenue or special obligation
                     bonds, private activity and industrial development bonds
                     and participation interests in municipal bonds.
REPURCHASE AGREEMENTS
                     Repurchase agreements are arrangements by which a Portfolio
                     obtains a security and simultaneously commits to return the
                     security to the seller at an agreed upon price (including
                     principal and interest) on an agreed upon date within a
                     number of days from the date of purchase. Repurchase
                     agreements are considered loans under the 1940 Act.
STANDBY COMMITMENTS AND
PUTS
                     Securities subject to standby commitments or puts permit
                     the holder thereof to sell the securities at a fixed price
                     prior to maturity. Securities subject to a standby
                     commitment or put may be sold at any time at the current
                     market price. However, unless the standby commitment or put
                     was an integral part of the security as originally issued,
                     it may not be marketable or assignable; therefore, the
                     standby commitment or put would only have value to the
                     Portfolio owning the security to which it relates. In
                     certain cases, a premium
 
                                                                              13
<PAGE>
                     may be paid for a standby commitment or put, which premium
                     will have the effect of reducing the yield otherwise
                     payable on the underlying security. The Portfolio will
                     limit standby commitment or put transactions to
                     institutions believed to present minimal credit risks.
U.S. GOVERNMENT
OBLIGATIONS
                     Obligations issued by the U.S. Treasury or issued or
                     guaranteed by agencies of the U.S. Government and
                     obligations issued or guaranteed by instrumentalities of
                     the U.S. Government. Some of these securities are supported
                     by the full faith and credit of the U.S. Treasury (E.G.,
                     Government National Mortgage Association securities),
                     others are supported by the right of the issuer to borrow
                     from the Treasury (E.G., Federal Farm Credit Bank
                     securities), while still others are supported only by the
                     credit of the instrumentality (E.G., Fannie Mae
                     securities).
VARIABLE AND FLOATING
RATE INSTRUMENTS
                     Certain of the obligations purchased by the Portfolio may
                     carry variable or floating rates of interest and may
                     involve a conditional or unconditional demand feature. Such
                     obligations may include variable amount master demand
                     notes. Such instruments bear interest at rates which are
                     not fixed, but which vary with changes in specified market
                     rates or indices. The interest rates on these securities
                     may be reset daily, weekly, quarterly or at some other
                     interval, and may have a floor or ceiling on interest rate
                     changes. There is a risk that the current interest rate on
                     such obligations may not accurately reflect existing market
                     interest rates. A demand instrument with a demand notice
                     period exceeding seven days may be considered illiquid if
                     there is no secondary market for such security.
WHEN-ISSUED AND DELAYED
DELIVERY SECURITIES
                     When-issued or delayed delivery transactions involve the
                     purchase of an instrument with payment and delivery taking
                     place in the future. Delivery of and payment for these
                     securities may occur a month or more after the date of the
                     purchase commitment. The Portfolio will maintain with the
                     custodian a separate account with liquid securities or cash
                     in an amount at least equal to these commitments. The
                     interest rate realized on these securities is fixed as of
                     the purchase date, and no interest accrues to the Portfolio
                     before settlement.
 
                                                                              14

CALIFORNIA TAX EXEMPT PORTFOLIO
 
- --------------------------------------------------------------------------------
 
This Prospectus sets forth concisely information about the above-referenced
Portfolio that an investor needs to know before investing. Please read this
Prospectus carefully, and keep it on file for future reference.
 
A Statement of Additional Information dated December 31, 1997, has been filed
with the Securities and Exchange Commission and is available upon request and
without charge by writing the Distributor, SEI Investments Distribution Co.,
Oaks, Pennsylvania 19456, or by calling 1-800-342-5734. The Statement of
Additional Information is incorporated into this Prospectus by reference.
 
SEI Tax Exempt Trust (the "Trust") is an open-end investment management company,
certain classes of which offer financial institutions a convenient means of
investing their own funds, or funds for which they act in a fiduciary, agency or
custodial capacity, in one or more professionally managed diversified and
non-diversified portfolios of securities. A portfolio may offer separate classes
of shares that differ from each other primarily in the allocation of certain
expenses and minimum investment amounts. This Prospectus offers Class A, Class B
and Class C shares of the Trust's California Tax Exempt Portfolio, a money
market portfolio (the "Portfolio").
 
AN INVESTMENT IN THE PORTFOLIO IS NEITHER INSURED NOR GUARANTEED BY THE U.S.
GOVERNMENT, AND THERE CAN BE NO ASSURANCE THAT THE PORTFOLIO WILL BE ABLE TO
MAINTAIN A STABLE NET ASSET VALUE OF $1.00 PER SHARE. IN ADDITION, THE PORTFOLIO
MAY INVEST A SIGNIFICANT PERCENTAGE OF ITS ASSETS IN A SINGLE ISSUER, AND
INVESTING IN THE PORTFOLIO MAY BE RISKIER THAN INVESTING IN OTHER TYPES OF MONEY
MARKET FUNDS.
 
- --------------------------------------------------------------------------------
 
 THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
 EXCHANGE COMMISSION, NOR HAS THE SECURITIES AND EXCHANGE COMMISSION PASSED
 UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE
 CONTRARY IS A CRIMINAL OFFENSE.
 
 THE TRUST'S SHARES ARE NOT DEPOSITS OR OBLIGATIONS OF, OR GUARANTEED OR
 ENDORSED BY, ANY BANK. THE SHARES ARE NOT FEDERALLY INSURED BY THE FEDERAL
 DEPOSIT INSURANCE CORPORATION, THE FEDERAL RESERVE BOARD OR ANY OTHER
 GOVERNMENT AGENCY. INVESTMENT IN THE SHARES INVOLVES RISK, INCLUDING POSSIBLE
 LOSS OF THE PRINCIPAL AMOUNT INVESTED.

INVESTMENT OBJECTIVE
AND POLICIES
     ___________________________________________________________________________
 
                     The Portfolio's investment objective is to preserve
                     principal value and maintain a high degree of liquidity
                     while providing current income exempt from federal and, to
                     the extent possible, California state personal income
                     taxes. There can be no assurance that the Portfolio will
                     achieve its investment objective.
 
                           It is a fundamental policy of the Portfolio to
                     invest, under normal conditions, at least 80% of its net
                     assets in municipal securities that produce interest that,
                     in the opinion of bond counsel, is exempt from federal
                     income tax (collectively, "Municipal Securities"), and the
                     Portfolio will invest, under normal conditions, at least
                     80% of its net assets in securities the interest on which
                     is not a preference item for purposes of the federal
                     alternative minimum tax. Under normal conditions, at least
                     65% of the Portfolio's assets will be invested in municipal
                     obligations the interest on which is exempt from California
                     state personal income tax. These constitute municipal
                     obligations of the state of California and its political
                     subdivisions or municipal authorities and municipal
                     obligations issued by territories or possessions of the
                     United States. The Portfolio may invest, under normal
                     conditions, up to 20% of its net assets in (1) Municipal
                     Securities the interest on which is a preference item for
                     purposes of the federal alternative minimum tax (although
                     the Portfolio has no present intention of investing in such
                     securities) and (2) taxable investments. In addition, for
                     temporary defensive purposes when Weiss, Peck & Greer,
                     L.L.C., the Portfolio's investment adviser (the "Adviser"
                     or "WPG"), determines that market conditions warrant, the
                     Portfolio may invest up to 100% of its assets in municipal
                     obligations of states other than California or taxable
                     money market securities.
 
                           The Adviser will not invest more than 25% of the
                     Portfolio's assets in Municipal Securities the interest on
                     which is derived from revenues of similar type projects.
                     This restriction does not apply to Municipal Securities in
                     any of the following categories: public housing
                     authorities; general obligations of states and localities;
                     state and local housing finance authorities or municipal
                     utilities systems.
 
                                                                               4

GENERAL INVESTMENT
POLICIES
     ___________________________________________________________________________
 
                     In purchasing obligations, the Portfolio complies with the
                     requirements of Rule 2a-7 under the Investment Company Act
                     of 1940 (the "1940 Act"), as that Rule may be amended from
                     time to time. These requirements currently provide that the
                     Portfolio must limit its investments to securities with
                     remaining maturities of 397 days or less, and must maintain
                     a dollar-weighted average maturity of 90 days or less. In
                     addition, the Portfolio may only invest in eligible
                     securities. In general, this means securities rated in one
                     of the two highest categories for short-term securities by
                     at least two nationally recognized statistical rating
                     organizations ("NRSROs") (or by one NRSRO if only one NRSRO
                     has rated the security), or, if unrated, determined by the
                     Adviser to be of equivalent quality. Since the Portfolio
                     often purchases securities supported by credit enhancements
                     from banks and other financial institutions, changes in the
                     credit quality of these institutions could cause losses to
                     the Portfolio and affect its share price.
 
                           Securities rated in the highest rating category
                     (E.G., A-1 by Standard & Poor's Corporation ("S&P")) by at
                     least two NRSROs (or, if unrated, determined by the Adviser
                     to be of comparable quality) are "first tier" securities.
                     Non-first tier securities rated in the second highest
                     rating category (E.G., A-2 by S&P) by at least one NRSRO
                     (or, if unrated, determined by the Adviser to be of
                     comparable quality) are considered to be "second tier"
                     securities. The Portfolio's investments in non-first tier
                     conduit securities will be limited to 5% of the Portfolio's
                     assets. Conduit securities are securities issued to finance
                     non-governmental private projects, such as housing
                     developments and retirement homes, and for which the
                     ultimate obligor is not a governmental issuer.
 
                           The Portfolio may purchase municipal bonds, municipal
                     notes and tax-exempt commercial paper, but only if such
                     securities, at the time of purchase, either meet the rating
                     requirements imposed by Rule 2a-7 or, if not rated, are of
                     comparable quality as determined by the Adviser. See
                     "General Investment Policies."
 
                           The portfolio may invest in variable and floating
                     rate obligations, may purchase securities on a
                     "when-issued" basis, and reserves the right to engage in
                     transactions involving standby commitments. The Portfolio
                     will not invest more than 10% of its net assets in illiquid
                     securities.
 
                           For a description of the Portfolio's permitted
                     investments and ratings, see the "Description of Permitted
                     Investments and Risk Factors" and the Statement of

                     MONEY MARKET FUNDS THAT ARE DIVERSIFIED ACROSS ISSUERS
                     LOCATED IN A NUMBER OF STATES. Certain additional risks are
                     inherent in the Portfolio's concentrated
 
                                                                               5

                     investments in California Municipal Securities. These risks
                     result primarily from (1) amendments to the California
                     Constitution and other statutes that limit the taxing and
                     spending authority of California government entities, and
                     (2) a variety of California laws and regulations that may
                     affect, directly or indirectly, the issuer of California
                     Municipal Securities.
 
                           There could be economic, business, or political
                     developments which might affect all Municipal Securities of
                     a similar type. To the extent that a significant portion of
                     the Portfolio's assets are invested in Municipal Securities
                     payable from revenues on similar projects, the Portfolio
                     will be subject to the risks presented by such projects to
                     a greater extent than it would be if the Portfolio's assets
                     were not so invested. Moreover, in seeking to attain its
                     investment objective the Portfolio may invest all or any
                     part of its assets in Municipal Securities that are
                     industrial development bonds.
 
INVESTMENT
LIMITATIONS
        ________________________________________________________________________
 
                     The investment objective and investment limitations are
                     fundamental policies of the Portfolio. Fundamental policies
                     cannot be changed with respect to the Trust or the
                     Portfolio without the consent of the holders of a majority
                     of the Trust's or the Portfolio's outstanding shares. It is
                     a fundamental policy of the Portfolio to use its best
                     efforts to maintain a constant net asset value of $1.00 per
                     share.
 
                     THE PORTFOLIO MAY NOT:
 
                     1. Purchase securities of any issuer (except securities
                        issued or guaranteed by the United States Government,
                        its agencies or instrumentalities) if, as a result, more
                        than 5% of the total assets of the Portfolio (based on
                        current value at the time of investment) would be
                        invested in the securities of such issuer. This
                        restriction applies to 75% of the Portfolio's assets.
 
                     2. Purchase any securities which would cause more than 25%
                        of the total assets of the Portfolio, based on fair
                        market value at the time of such purchase, to be
                        invested in the securities of one or more issuers
                        conducting their principal business activities in the
                        same industry, provided that this limitation does not
                        apply to investments in obligations issued or guaranteed
                        by the United States Government or its agencies and
                        instrumentalities or to investments in tax-exempt
                        securities issued by governments or political
                        subdivisions of governments.
 
                     3. Borrow money except for temporary or emergency purposes
                        and then only in an amount not exceeding 10% of the
                        value of the total assets of the Portfolio. All
                        borrowings will be repaid before making additional
                        investments and any interest paid on such borrowings
                        will reduce the income of the Portfolio.
 
                                                                               6

                     The foregoing percentage limitations will apply at the time
                     of the purchase of a security. Additional fundamental
                     investment limitations are set forth in the Statement of
                     Additional Information.
THE MANAGER
          ______________________________________________________________________
 
                     SEI Fund Management (the "Manager" and the "Transfer
                     Agent") provides the Trust with overall management
                     services, regulatory reporting, all necessary office space,
                     equipment, personnel and facilities, and serves as
                     institutional transfer agent and dividend disbursing agent.
 
                           For these services, the Manager is entitled to a fee,
                     which is calculated daily and paid monthly, at an annual
                     rate of .23% of the average daily net assets of the
                     Portfolio. The Manager has voluntarily agreed to waive a
                     portion of its fees in order to limit the total operating
                     expenses of Class A, Class B and Class C shares of the
                     Portfolio to not more than .28%, .58% and .78% as a
                     percentage of the Portfolio's average daily net assets
                     attributable to Class A, Class B and Class C shares, on an
                     annualized basis, respectively. The Manager reserves the
                     right, in its sole discretion, to terminate these voluntary
                     fee waivers at any time. For the fiscal year ended August
                     31, 1997, the Portfolio paid management fees, after
                     waivers, of .19% of its average daily net assets.

                     Portfolio. Ms. Fiorenza, a Principal of the Adviser, has

                     Group since 1988, and with its predecessor since 1980.
 
                           For its services to the Portfolio, the Adviser is
                     entitled to a fee, which is calculated daily and paid

                     their relative net assets. For the fiscal year ended August
                     31, 1997, the Portfolio paid advisory fees, after waivers,
                     of .04% of its relative net assets.
 
DISTRIBUTION AND
SHAREHOLDER
SERVICING
      __________________________________________________________________________
 
                     SEI Investments Distribution Co. (the "Distributor"), a
                     wholly owned subsidiary of SEI Investments Company ("SEI
                     Investments"), serves as the Portfolio's distributor
                     pursuant to a distribution agreement (the "Distribution
                     Agreement") with the Trust.
 
                           The Portfolio has adopted plans under which firms,
                     including the Distributor, that provide shareholder and
                     administrative services may receive compensation therefor.
                     As discussed below, the Class A, B and C plans differ in a
                     number of ways, including the amounts that may be paid
                     under each plan. The Distributor may provide those services
                     itself or may enter into arrangements under which third
                     parties provide such services and are compensated by the
                     Distributor. Under such arrangements the Distributor may
                     retain as a profit any difference between the fee it
                     receives and the amount it pays to third parties.
 
                           Under the Class A plan, the Distributor is entitled
                     to receive a fee at an annual rate of up to .25% of the
                     average daily net assets of the Portfolio attributable to
                     Class A shares, in return for provision of a broad range of
                     shareholder and administrative services. Under the Class B
                     and Class C shareholder service plans, the Distributor is
                     entitled to receive shareholder service fees at an annual
                     rate of up to .25% of average daily net assets in return
                     for the Distributor's (or its agent's) efforts in
                     maintaining client accounts; arranging for bank wires;
                     responding to client inquiries concerning services provided
                     or investment; and assisting clients in changing dividend
                     options, account designations and addresses. In addition,
                     under their administrative service plans, Class B and Class
                     C shares also pay administrative services fees at specified
                     percentages of the average daily net assets of the shares
                     of the Class (up to .05% and .25%, respectively).
                     Administrative services include sub-accounting; providing
                     information on share positions to clients; forwarding
                     shareholder communications to clients; processing purchase,
                     exchange and redemption orders; and processing dividend
                     payments.
 
                           It is possible that an institution may offer
                     different classes of shares to its customers and differing
                     services to the classes of each Portfolio, and thus receive
                     different compensation with respect to different classes.
                     These financial institutions may also charge separate fees
                     to their customers.
 
                           The Trust may execute brokerage or other agency
                     transactions through the Distributor for which the
                     Distributor may receive usual and customary compensation.
 
                           The Distributor may, from time to time and at its own
                     expense, provide promotional incentives, in the form of
                     cash or other compensation to certain financial
                     institutions whose representatives have sold or are
                     expected to sell significant amounts of the Portfolio's
                     shares.
 
                                                                               8

PURCHASE AND
REDEMPTION OF SHARES
    ____________________________________________________________________________
 
                     Financial institutions may acquire shares of the Portfolio
                     for their own account, or as a record owner on behalf of
                     fiduciary, agency or custody accounts, by placing orders
                     with the Transfer Agent (or its authorized agent).
                     Institutions that use certain SEI proprietary systems may
                     place orders electronically through those systems.
                     Financial institutions may impose an earlier cut-off time
                     for receipt of purchase orders directed through them to
                     allow for processing and transmittal of these orders to the
                     Transfer Agent for effectiveness on the same day. Financial
                     institutions which purchase shares for the accounts of
                     their customers may impose separate charges on these
                     customers for account services.
 
                           Shares of the Portfolio may be purchased or redeemed
                     on days on which the New York Stock Exchange is open for
                     business ("Business Days"). However, money market fund
                     shares cannot be purchased by Federal Reserve wire on
                     Federal holidays on which wire transfers are restricted.
 
                           Shareholders who desire to purchase shares for cash
                     must place their orders with the Transfer Agent (or its
                     authorized agent) prior to the calculation of net asset
                     value on any Business Day for the order to be accepted on
                     that Business Day. Cash investments must be transmitted or
                     delivered in federal funds to the wire agent by the close
                     of business on the same day the order is placed. The Trust
                     reserves the right to reject a purchase order when the
                     Distributor determines that it is not in the best interest
                     of the Trust or shareholders to accept such purchase order.
 
                           The Trust will send shareholders a statement of
                     shares owned after each transaction. The purchase price of
                     shares is the net asset value next determined after a
                     purchase order is received and accepted by the Trust. The
                     purchase price of shares is expected to remain constant at
                     $1.00. The net asset value per share of the Portfolio is
                     determined by dividing the total value of its investments
                     and other assets, less any liabilities, by the total
                     outstanding shares of the Portfolio. The Portfolio's
                     investments will be valued by the amortized cost method
                     described in the Statement of Additional Information. Net
                     asset value per share is determined on each Business Day as
                     of 2:00 p.m., Eastern time.
 
                           Shareholders who desire to redeem shares of the
                     Portfolio must place their redemption orders with the
                     Transfer Agent (or its authorized agent) prior to the
                     calculation of net asset value on any Business Day in order
                     to be effective on that day. Otherwise, redemption orders
                     will be effective on the next Business Day. Payment for
                     redemption orders received before the calculation of net
                     asset value will be made the same day by transfer of
                     federal funds. The redemption price is the net asset value
                     per share of the Portfolio next determined after receipt by
                     the Transfer Agent (or its authorized agent) of an
                     effective redemption order.
 
                                                                               9
<PAGE>
                           Purchase and redemption orders may be placed by
                     telephone. Neither the Trust nor the Transfer Agent will be
                     responsible for any loss, liability, cost or expense for
                     acting upon wire instructions or upon telephone
                     instructions that it reasonably believes to be genuine. The
                     Trust and the Transfer Agent will each employ reasonable
                     procedures to confirm that instructions communicated by
                     telephone are genuine, including requiring a form of
                     personal identification prior to acting upon instructions
                     received by telephone and recording telephone instructions.
 
                           If market conditions are extraordinarily active, or
                     other extraordinary circumstances exist, shareholders may
                     experience difficulties placing redemption orders by
                     telephone, and may wish to consider placing orders by other
                     means.
PERFORMANCE
          ______________________________________________________________________
 
                     From time to time the Portfolio advertises its "current
                     yield," "tax equivalent yield" and "effective yield." These
                     figures are based on historical earnings and are not
                     intended to indicate future performance. The "current
                     yield" of the Portfolio refers to the income generated by
                     an investment over a seven-day period which is then
                     "annualized." That is, the amount of income generated by
                     the investment during the 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" (also
                     called "effective compound yield") is calculated similarly
                     but, when annualized, the income earned by an investment is
                     assumed to be reinvested. The "effective yield" will be
                     slightly higher than the "current yield" because of the
                     compounding effect of this assumed reinvestment. The "tax
                     equivalent yield" is calculated by determining the rate of
                     return that would have been achieved on a fully taxable
                     investment to produce the after-tax equivalent of the
                     Portfolio's yield, assuming certain tax brackets for a
                     shareholder.
 
                           The Portfolio may periodically compare its
                     performance to that of: (i) other mutual funds tracked by
                     mutual fund rating services (such as Lipper Analytical),
                     financial and business publications and periodicals; (ii)
                     broad groups of comparable mutual funds; (iii) unmanaged
                     indices which may assume investment of dividends but
                     generally do not reflect deductions for administrative and
                     management costs; or (iv) other investment alternatives.
 
                           The performance of Class A shares of the Portfolio
                     will normally be higher than that of Class B, Class C or
                     CNI Class shares because of the additional distribution
                     and/or administrative services expenses charged to Class B,
                     Class C and CNI Class shares.
TAXES

                     The following summary of federal and state income tax
                     consequences is based on current tax laws and regulations,
                     which may be changed by legislative, judicial or
                     administrative
 
                                                                              10

                     action. No attempt has been made to present a detailed
                     explanation of the federal, state or local income tax
                     treatment of the Portfolio or its shareholders.
                     Accordingly, shareholders are urged to consult their tax
                     advisers regarding specific questions as to federal, state
                     and local income taxes. Additional information concerning
                     taxes is set forth in the Statement of Additional
                     Information.
TAX STATUS OF EACH
PORTFOLIO
                     The Portfolio is treated as a separate entity for federal
                     income tax purposes and is not combined with the Trust's
                     other portfolios. The Portfolio intends to continue to
                     qualify for the special tax treatment afforded regulated
                     investment companies under Subchapter M of the Internal
                     Revenue Code of 1986, as amended (the "Code"), so as to be
                     relieved of federal income tax on net investment company
                     taxable income and net capital gain (the excess of net
                     long-term capital gain over net short-term capital loss)
                     distributed to shareholders.
TAX STATUS OF
DISTRIBUTIONS
                     The Portfolio intends to distribute substantially all of
                     its net investment income (including net short-term capital
                     gain) to shareholders. If, at the close of each quarter of
                     its taxable year, at least 50% of the value of the
                     Portfolio's total assets consists of obligations the
                     interest on which is excludable from gross income, the
                     Portfolio may pay "exempt-interest dividends" to its
                     shareholders. Exempt-interest dividends are excludable from
                     a shareholder's gross income for federal income tax
                     purposes but may have certain collateral federal tax
                     consequences including alternative minimum tax
                     consequences. In addition, the receipt of exempt-interest
                     dividends may cause persons receiving Social Security or
                     Railroad Retirement benefits to be taxable on a portion of
                     such benefits. See the Statement of Additional Information.
 
                           Any dividends paid out of income realized by the
                     Portfolio on taxable securities will be taxable to
                     shareholders as ordinary income (whether received in cash
                     or in additional shares) to the extent of the Portfolio's
                     earnings and profits and will not qualify for the
                     dividends-received deduction for corporate shareholders.
                     Distributions to shareholders of net capital gains of the
                     Portfolio also will not qualify for the dividends received
                     deduction and will be taxable to shareholders as long-term
                     capital gain, whether received in cash or additional
                     shares, and regardless of how long a shareholder has held
                     the shares.
 
                           Dividends declared by the Portfolio in October,
                     November or December of any year and payable to
                     shareholders of record on a date in any such month will be
                     deemed to have been paid by the Portfolio and received by
                     the shareholders on December 31 of that year if paid by the
                     Portfolio at any time during the following January. The
                     Portfolio intends to make sufficient distributions prior to
                     the end of each calendar year to avoid liability for the
                     federal excise tax applicable to regulated investment
                     companies.
 
                           Interest on indebtedness incurred or continued by a
                     shareholder in order to purchase or carry shares of the
                     Portfolio is not deductible for federal income tax purposes
                     to the extent that it relates to exempt-interest dividends
                     distributed to the shareholder during the taxable year.
                     Furthermore, the Portfolio may not be an appropriate
                     investment
 
                                                                              11

                     for persons (including corporations and other business
                     entities) who are "substantial users" (or persons related
                     to "substantial users") of facilities financed by
                     industrial development bonds or private activity bonds.
                     Such persons should consult their tax advisers before
                     purchasing shares. The Portfolio will report annually to
                     its shareholders the portion of dividends that is taxable
                     and the portion that is tax-exempt based on income received
                     by the Portfolio during the year to which the dividends
                     relate.
 
                           Each sale, exchange or redemption of the Portfolio's
                     shares is a taxable transaction to the shareholder.
CALIFORNIA TAXES
                     The following is a general, abbreviated summary of certain
                     of the provisions of the California Revenue and Taxation
                     Code presently in effect as they directly govern the
                     taxation of shareholders subject to California personal
                     income tax. These provisions are subject to change by
                     legislative or administrative action, and any such change
                     may be retroactive.
 
                           The Portfolio intends to qualify to pay dividends to
                     shareholders that are exempt from California personal
                     income tax ("California exempt-interest dividends"). The
                     Portfolio will qualify to pay California exempt-interest
                     dividends if (1) at the close of each quarter of the
                     Portfolio's taxable year, at least 50% of the value of the
                     Portfolio's total assets consists of obligations the
                     interest on which would be exempt from California personal
                     income tax if the obligations were held by an individual
                     ("California Tax Exempt Obligations") and (2) the Portfolio
                     continues to qualify as a regulated investment company. The
                     Portfolio will notify its shareholders of the amount of
                     exempt-interest dividends each year.
 
                           If the Portfolio qualifies to pay California
                     exempt-interest dividends, dividends distributed to
                     shareholders will be considered California exempt-interest
                     dividends if they meet certain requirements. See the
                     Statement of Additional Information.
 
                           Corporations subject to California franchise tax that
                     invest in the Portfolio may not be entitled to exclude
                     California exempt-interest dividends from income.
 
                           Distributions that do not qualify for treatment as
                     California exempt-interest dividends (including those
                     distributions to shareholders taxable as long-term capital
                     gains for federal income tax purposes) will be taxable to
                     shareholders at ordinary income tax rates for California
                     personal income tax purposes to the extent of the
                     Portfolio's earnings and profits.
 
                           Interest on indebtedness incurred or continued by a
                     shareholder in connection with the purchase of shares of
                     the Portfolio will not be deductible for California
                     personal income tax purposes if the Portfolio distributes
                     California exempt-interest dividends.
 
GENERAL INFORMATION
         _______________________________________________________________________
THE TRUST
                     The Trust was organized as a Massachusetts business trust
                     under a Declaration of Trust dated March 15, 1982. The
                     Declaration of Trust permits the Trust to offer separate
                     portfolios of shares and different classes of each
                     portfolio. In addition to the Portfolios, the
 
                                                                              12
<PAGE>
                     Trust consists of the following portfolios: Tax Free
                     Portfolio, Institutional Tax Free Portfolio,
                     Intermediate-Term Municipal Portfolio, Pennsylvania
                     Municipal Portfolio, New York Intermediate-Term Municipal
                     Portfolio, and Pennsylvania Tax Free Portfolio. All
                     consideration received by the Trust for shares of any
                     portfolio and all assets of such portfolio belong to that
                     portfolio and would be subject to liabilities related
                     thereto.
 
                           The Trust pays its expenses, including fees of its
                     service providers, audit and legal expenses, expenses of
                     preparing prospectuses, proxy solicitation materials and
                     reports to shareholders, costs of custodial services and
                     registering the shares under federal and state securities
                     laws, pricing, insurance expenses, litigation and other
                     extraordinary expenses, brokerage costs, interest charges,
                     taxes and organization expenses.
TRUSTEES OF THE TRUST
                     The management and affairs of the Trust are supervised by
                     the Trustees under the laws of the Commonwealth of
                     Massachusetts. The Trustees have approved contracts under
                     which, as described above, certain companies provide
                     essential services to the Trust.
VOTING RIGHTS
                     Each share held entitles the shareholder of record to one
                     vote. The shareholders of each portfolio or class will vote
                     separately on matters relating solely to that portfolio or
                     class, such as any distribution plan. As a Massachusetts
                     business trust, the Trust is not required to hold annual
                     meetings of shareholders, but approval will be sought for
                     certain changes in the operation of the Trust and for the
                     election of Trustees under certain circumstances. In
                     addition, a Trustee may be removed by the remaining
                     Trustees or by shareholders at a special meeting called
                     upon written request of shareholders owning at least 10% of
                     the outstanding shares of the Trust. In the event that such
                     a meeting is requested, the Trust will provide appropriate
                     assistance and information to the shareholders requesting
                     the meeting.
REPORTING
                     The Trust issues unaudited financial statements
                     semi-annually and audited financial statements annually.
                     The Trust furnishes proxy statements and other reports to
                     shareholders of record.
SHAREHOLDER INQUIRIES
                     Shareholder inquiries should be directed to the Manager.

DIVIDENDS
                     The net investment income (exclusive of capital gains) of
                     the Portfolio is distributed in the form of dividends. The
                     Portfolio declares dividends daily, and shareholders of
                     record at the close of each Business Day will be entitled
                     to receive that day's dividend. Dividends are paid on the
                     first Business Day of each month. Dividends will be paid on
                     the next Business Day to shareholders who redeem all of
                     their shares of the Portfolio at any time during the month.
                     If any net capital gains are realized by the Portfolio,
                     they will be distributed annually. Shareholders
                     automatically receive all income dividends and capital gain
                     distributions in additional shares, unless the shareholder
                     has elected to take such payment in cash. Shareholders may
                     change their election by providing written notice to the
                     Manager at least 15 days prior to the distribution.
 
                                                                              13
<PAGE>
                           The dividends on Class A shares of the Portfolio are
                     normally higher than those on Class B, Class C or CNI Class
                     shares because of the additional distribution and/or
                     administrative services expenses charged to Class B, Class
                     C and CNI Class shares.

                     Government; and (iii) repurchase agreements involving any
                     of the foregoing obligations entered into with highly-rated
                     banks and broker-dealers.
MUNICIPAL SECURITIES
                     Municipal Securities consist of (i) debt obligations issued
                     by or on behalf of public authorities to obtain funds to be
                     used for various public facilities, for refunding
                     outstanding obligations, for general operating expenses and
                     for lending such funds to other public institutions and
                     facilities, and (ii) certain private activity and
                     industrial development bonds issued by or on behalf of
                     public authorities to obtain funds to provide for the
                     construction, equipment, repair or improvement of privately
                     operated facilities.
 
                           General obligation bonds are backed by the taxing
                     power of the issuing municipality. Revenue bonds are backed
                     by the revenues of a project or facility, tolls from a toll
                     bridge, for example. Certificates of participation
                     represent an interest in an underlying obligation or
                     commitment such as an obligation issued in connection with
                     a leasing arrangement. The payment of principal and
                     interest on private activity and industrial development
                     bonds generally is dependent solely on the ability of the
                     facility's user to meet its financial obligations and the
                     pledge, if any, of real and personal property so financed
                     as security for such payment.
 
                           Municipal notes include general obligation notes, tax
                     anticipation notes, revenue anticipation notes, bond
                     anticipation notes, certificates of indebtedness, demand
                     notes and construction loan notes and participation
                     interests in municipal notes. Municipal bonds
 
                                                                              14
<PAGE>
                     include general obligation bonds, revenue or special
                     obligation bonds, private activity and industrial
                     development bonds and participation interests in municipal
                     bonds.
REPURCHASE AGREEMENTS
                     Repurchase agreements are arrangements by which a Portfolio
                     obtains a security and simultaneously commits to return the
                     security to the seller at an agreed upon price (including
                     principal and interest) on an agreed upon date within a
                     number of days from the date of purchase. Repurchase
                     agreements are considered loans under the 1940 Act.
STANDBY COMMITMENTS AND
PUTS
                     Securities subject to standby commitments or puts permit
                     the holder thereof to sell the securities at a fixed price
                     prior to maturity. Securities subject to a standby
                     commitment or put may be sold at any time at the current
                     market price. However, unless the standby commitment or put
                     was an integral part of the security as originally issued,
                     it may not be marketable or assignable; therefore, the
                     standby commitment or put would only have value to the
                     Portfolio owning the security to which it relates. In
                     certain cases, a premium may be paid for a standby
                     commitment or put, which premium will have the effect of
                     reducing the yield otherwise payable on the underlying
                     security. The Portfolio will limit standby commitment or
                     put transactions to institutions believed to present
                     minimal credit risks.
U.S. GOVERNMENT
OBLIGATIONS
                     Obligations issued by the U.S. Treasury or issued or
                     guaranteed by agencies of the U.S. Government and
                     obligations issued or guaranteed by instrumentalities of
                     the U.S. Government. Some of these securities are supported
                     by the full faith and credit of the U.S. Treasury (e.g.,
                     Government National Mortgage Association securities),
                     others are supported by the right of the issuer to borrow
                     from the Treasury (e.g., Federal Farm Credit Bank
                     securities), while still others are supported only by the
                     credit of the instrumentality (e.g., Fannie Mae
                     securities).
VARIABLE AND FLOATING
RATE INSTRUMENTS
                     Certain of the obligations purchased by the Portfolio may
                     carry variable or floating rates of interest and may
                     involve a conditional or unconditional demand feature. Such
                     obligations may include variable amount master demand
                     notes. Such instruments bear interest at rates which are
                     not fixed, but which vary with changes in specified market
                     rates or indices. The interest rates on these securities
                     may be reset daily, weekly, quarterly or at some other
                     interval, and may have a floor or ceiling on interest rate
                     changes. There is a risk that the current interest rate on
                     such obligations may not accurately reflect existing market
                     interest rates. A demand instrument with a demand notice
                     period exceeding seven days may be considered illiquid if
                     there is no secondary market for such security.
WHEN-ISSUED AND DELAYED
DELIVERY SECURITIES
                     When-issued or delayed delivery transactions involve the
                     purchase of an instrument with payment and delivery taking
                     place in the future. Delivery of and payment for these
                     securities may occur a month or more after the date of the
                     purchase commitment. The Portfolio will maintain with the
                     custodian a separate account with liquid securities or cash
                     in an amount at least equal to these commitments. The
                     interest rate realized on these securities is fixed as of
                     the purchase date, and no interest accrues to the Portfolio
                     before settlement.
 
                                                                              15

INVESTMENT
OBJECTIVES AND
POLICIES
     ___________________________________________________________________________
 
                     The Portfolio's investment objective is to seek the highest
                     level of income exempt from federal income taxes that can
                     be obtained, consistent with the preservation of capital,
                     from a diversified portfolio of investment grade municipal
                     securities. There can be no assurance that the Portfolio
                     will achieve its investment objective.
 
                           The Portfolio invests at least 80% of its net assets
                     in municipal securities the interest of which is exempt
                     from federal income taxes (collectively "Municipal
                     Securities"), based on opinions from bond counsel for the
                     issuers. This investment policy is a fundamental policy of
                     the Portfolio. The issuers of these securities can be
                     located in all fifty states, the District of Columbia,
                     Puerto Rico, and other U.S. territories and possessions.
                     Under normal conditions, the Portfolio will invest at least
                     80% of its net assets in securities the interest on which
                     is not a preference item for purposes of the federal
                     alternative minimum tax. Although the advisers have no
                     present intention of doing so, up to 20% of all assets in
                     the Portfolio can be invested in taxable debt securities
                     for defensive purposes or when sufficient tax exempt
                     securities considered appropriate by the advisers are not
                     available for purchase.
 
                           The Portfolio may purchase the following types of
                     municipal obligations, but only if such securities, at the
                     time of purchase, either have the requisite rating, or, if
                     not rated, are of comparable quality as determined by the
                     advisers: (i) municipal bonds rated A or better by Standard
                     and Poor's Corporation ("S&P") or by Moody's Investors
                     Service, Inc. ("Moody's"), and the Portfolio may invest up
                     to 10% of its total assets in municipal bonds rated BBB by
                     S&P or Baa by Moody's; (ii) municipal notes rated at least
                     SP-1 by S&P or MIG-1 or VMIG-1 by Moody's; and (iii)
                     tax-exempt commercial paper rated at least A-1 by S&P or
                     Prime-1 by Moody's. Bonds rated BBB by S&P or Baa by
                     Moody's have speculative characteristics. Municipal
                     obligations owned by the Portfolio which become less than
                     the prescribed investment quality shall be sold at a time
                     when, in the judgment of the advisers, it does not
                     substantially impact the market value of the Portfolio.
 
                           Not more than 25% of Portfolio assets will be
                     invested in (a) Municipal Securities whose issuers are
                     located in the same state and, (b) Municipal Securities the
                     interest on which is derived from revenues of similar type
                     projects. This restriction does not apply to
 
                                                                               4
<PAGE>
                     Municipal Securities in any of the following categories:
                     public housing authorities; general obligations of states
                     and localities; state and local housing finance
                     authorities, or municipal utilities systems.
 
                           There could be economic, business, or political
                     developments which might affect all Municipal Securities of
                     a similar type. To the extent that a significant portion of
                     the Portfolio's assets are invested in Municipal Securities
                     payable from revenues on similar projects, the Portfolio
                     will be subject to the peculiar risks presented by such
                     projects to a greater extent than it would be if the
                     Portfolio's assets were not so invested.
 
                           The Portfolio will typically maintain a
                     dollar-weighted average portfolio maturity of three to ten
                     years. However, when the advisers determine that market
                     conditions so warrant, the Portfolio can maintain an
                     average weighted maturity of less than three years.
 
GENERAL INVESTMENT
POLICIES
     ___________________________________________________________________________
 
                     The Portfolio may invest in variable and floating rate
                     obligations, may purchase securities on a "when-issued"
                     basis, and reserves the right to engage in transactions
                     involving standby commitments. The Portfolio may also
                     purchase other types of tax-exempt instruments as long as
                     they are of a quality equivalent to the long-term bond or
                     commercial paper ratings stated above. Although permitted
                     to do so, the Portfolio has no present intention to invest
                     in repurchase agreements or to purchase securities subject
                     to the federal alternative minimum tax. The Portfolio will
                     not invest more than 15% of its net assets in illiquid
                     securities.
 
                           The taxable securities in which the Portfolio may
                     invest consist of U.S. Treasury obligations; obligations
                     issued or guaranteed by the U.S. Government or by its
                     agencies or instrumentalities whether or not backed by the
                     full faith and credit of the U.S. Government; instruments
                     of U.S. commercial banks or savings and loan institutions
                     (not including foreign branches of U.S. banks or U.S.
                     branches of foreign banks) which are members of the Federal
                     Reserve System or the Federal Deposit Insurance Corporation
                     and which have total assets of $1 billion or more as shown
                     on their last published financial statements at the time of
                     investment; and repurchase agreements involving any of such
                     obligations.
 
                           For a description of the permitted investments and
                     ratings, see the "Description of Permitted Investments and
                     Risk Factors" and the Statement of Additional Information.

                     The investment objective and investment limitations are
                     fundamental policies of the Portfolio. Fundamental policies
                     cannot be changed with respect to the Trust or the
 
                                                                               5

                     Portfolio without the consent of the holders of a majority
                     of the Trust's or the Portfolio's outstanding shares.
 
                     THE PORTFOLIO MAY NOT:
 
                     1. Purchase securities of any issuer (except securities
                        issued or guaranteed by the United States Government,
                        its agencies or instrumentalities and any security
                        guaranteed thereby) if, as a result, more than 5% of the
                        total assets of the Portfolio (based on fair market
                        value at time of investment) would be invested in the
                        securities of such issuer; provided, however, that the
                        Portfolio may invest up to 25% of its total assets
                        without regard to this restriction.
 
                     2. Purchase any securities which would cause more than 25%
                        of the total assets of the Portfolio, based on current
                        value at the time of such purchase, to be invested in
                        the securities of one or more issuers conducting their
                        principal business activities in the same industry,
                        provided that this limitation does not apply to
                        investments in obligations issued or guaranteed by the
                        U.S. Government or its agencies and instrumentalities or
                        to investments in tax-exempt securities issued by
                        governments or political subdivisions of governments.
 
                     3. Borrow money except for temporary or emergency purposes
                        and then only in an amount not exceeding 10% of the
                        value of the total assets of the Portfolio. All
                        borrowings will be repaid before making additional
                        investments and any interest paid on such borrowings
                        will reduce the income of the Portfolio.
 
                     The foregoing percentage limitations will apply at the time
                     of the purchase of a security. Additional fundamental
                     investment limitations are set forth in the Statement of
                     Additional Information.
THE MANAGER
          ______________________________________________________________________
 
                     SEI Fund Management (the "Manager" and the "Transfer
                     Agent") provides the Trust with overall management
                     services, regulatory reporting, all necessary office space,
                     equipment, personnel and facilities, and serves as
                     institutional transfer agent and dividend disbursing agent.
 
                           For these services, the Manager is entitled to a fee,
                     which is calculated daily and paid monthly, at an annual
                     rate of .24% of the average daily net assets of the
                     Portfolio. In addition, the Manager has voluntarily agreed
                     to waive a portion of its fees proportionately in order to
                     limit total operating expenses of the Class A shares of the
                     Portfolio to not more than .60% of the Portfolio's average
                     daily net assets attributable to Class A shares, on an
                     annualized basis. The Manager reserves the right, in its
                     sole discretion, to terminate its waiver at any time. For
                     the fiscal year ended August 31, 1997, the Portfolio paid
                     management fees, after waivers, of .22% of its average
                     daily net assets.
 
                                                                               6

SEI INVESTMENTS
MANAGEMENT CORPORATION
                     SEI Investments Management Corporation ("SIMC") serves as
                     investment adviser to the Portfolio. SIMC is a wholly-owned
                     subsidiary of SEI Investments Company ("SEI Investments"),
                     a financial services company. The principal business
                     address of SIMC and SEI Investments is Oaks, Pennsylvania
                     19456. SEI Investments was founded in 1968 and is a leading
                     provider of investment solutions to banks, institutional

                     Affiliates of SIMC have provided consulting advice to

                     $99.9 billion in assets as of September 30, 1997.
 
                           SIMC acts as the investment adviser to the Portfolio
                     and operates as a "manager of managers." As Adviser, SIMC
                     oversees the investment advisory services provided to the
                     Portfolio and manages the cash portion of the Portfolio's
                     assets. Pursuant to a separate sub-advisory agreement with
                     SIMC, and under the supervision of the Adviser and the
                     Board of Trustees, the sub-adviser is responsible for the
                     day-to-day investment management of all or a discrete
                     portion of the assets of the Portfolio. Sub-advisers are
                     selected based primarily upon the research and
                     recommendations of SIMC, which evaluate quantitatively and

                     sub-adviser compliance with the Portfolio's investment
                     objectives, policies and restrictions. SIMC HAS THE
                     ULTIMATE RESPONSIBILITY FOR THE INVESTMENT PERFORMANCE OF

                           For these advisory services, SIMC is entitled to a
                     fee, which is calculated daily and paid monthly, at an
                     annual rate of .33% of the Portfolio's average daily net
                     assets. For the fiscal year ended August 31, 1997, the
                     Portfolio paid advisory fees, after waivers, of .33% of its
                     average daily net assets. SIMC pays the sub-advisers out
                     its investment advisory fees.
 
                           SIMC and the Trust have obtained an exemptive order
                     from the Securities and Exchange Commission ("SEC") that
                     permits SIMC, with the approval of the Trust's Board of
                     Trustees, to retain sub-advisers unaffiliated with SIMC for
                     the Portfolio without submitting the sub-advisory
                     agreements to a vote of the Portfolio's shareholders. The
                     exemptive relief permits the disclosure of only the
                     aggregate amount payable by SIMC under all such
                     sub-advisory agreements. The Portfolio will notify
                     shareholders in the event of any addition or change in the
                     identity of its sub-advisers.

DISTRIBUTION AND
SHAREHOLDER
SERVICING
      __________________________________________________________________________
 
                     SEI Investments Distribution Co. (the "Distributor"), a
                     wholly-owned subsidiary of SEI Investments, serves as the
                     Portfolio's distributor pursuant to a distribution
                     agreement with the Trust.
 
                           The Portfolio has adopted a shareholder servicing
                     plan for Class A shares (the "Service Plan") under which
                     the Distributor is entitled to receive a shareholder
                     servicing fee of up to .25% of average daily net assets
                     attributable to Class A shares. Under the Service Plan, the
                     Distributor may perform, or may compensate other service
                     providers for performing the following shareholder and
                     administrative services: maintaining client accounts;
                     arranging for bank wires; responding to client inquiries
                     concerning services provided on investments; assisting
                     clients in changing dividend options; account designations
                     and addresses; sub-accounting; providing information on
                     share positions to clients; forwarding shareholder
                     communications to clients; processing purchase, exchange
                     and redemption orders; and processing dividend payments.
                     Under the Service Plan, the Distributor may retain as a
                     profit any difference between the fee it receives and the
                     amount it pays to third parties.
 
                           It is possible that an institution may offer
                     different classes of shares to its customers and thus
                     receive different compensation with respect to different
                     classes. These financial institutions may also charge
                     separate fees to their customers.
 
                           The Trust may also execute brokerage or other agency
                     transactions through the Distributor for which the
                     Distributor may receive usual and customary compensation.
 
                                                                               8
<PAGE>
                           The Distributor may, from time to time and at its own
                     expense, provide promotional incentives, in the form of
                     cash or other compensation to certain financial
                     institutions whose representatives have sold or are
                     expected to sell significant amounts of the Portfolio's
                     shares.
 
PURCHASE AND
REDEMPTION OF SHARES
    ____________________________________________________________________________
 
                     Financial institutions may acquire shares of the Portfolio
                     for their own account, or as a record owner on behalf of
                     fiduciary, agency or custody accounts, by placing orders
                     with the Transfer Agent (or its authorized agent).
                     Institutions that use certain SEI proprietary systems may
                     place orders electronically through those systems.
                     Financial institutions which purchase shares for the
                     accounts of their customers may impose separate charges on
                     these customers for account services. Financial
                     institutions may impose an earlier cut-off time for receipt
                     of purchase orders directed through them to allow for
                     processing and transmittal of these orders to the Transfer
                     Agent for effectiveness on the same day.
 
                           Shares of the Portfolio may be purchased or redeemed
                     on days on which the New York Stock Exchange is open for
                     business ("Business Days").
 
                           Shareholders who desire to purchase shares for cash
                     must place their orders with the Transfer Agent (or its
                     authorized agent) prior to the determination of net asset
                     value and in accordance with the procedures described below
                     for the order to be accepted on that Business Day. Cash
                     investments must be transmitted or delivered in federal
                     funds to the wire agent by the close of business on the
                     same day the order is placed. The Trust reserves the right
                     to reject a purchase order when the Distributor determines
                     that it is not in the best interest of the Trust and/or
                     shareholders to accept such purchase order.
 
                           Purchases will be made in full and fractional shares
                     of the Portfolio calculated to three decimal places. The
                     Trust will send shareholders a statement of shares owned
                     after each transaction. The purchase price of shares is the
                     net asset value next determined after a purchase order is
                     received and accepted by the Trust. The net asset value per
                     share of the Portfolio is determined by dividing the total
                     value of its investments and other assets, less any
                     liabilities, by the total number of outstanding shares of
                     the Portfolio. Net asset value per share is determined
                     daily as of the close of trading on the New York Stock
                     Exchange (presently 4:00 p.m., Eastern time) on each
                     Business Day.
 
                           Information about the market value of each portfolio
                     security may be obtained by the Manager from an independent
                     pricing service. Securities having maturities of 60 days or
                     less at the time of purchase will be valued using the
                     amortized cost method (described in the Statement of
                     Additional Information), which approximates the securities'
                     market value. The pricing service may use a matrix system
                     to determine valuations of fixed income securities. This
                     system considers such factors as security prices, yields,
                     maturities, call features, ratings and developments
                     relating to specific securities in arriving at valuations.
 
                                                                               9
<PAGE>
                     The pricing service may also provide market quotations. The
                     procedures used by the pricing service and its valuations
                     are reviewed by the officers of the Trust under the general
                     supervision of the Trustees. Portfolio securities for which
                     market quotations are available are valued at the last
                     quoted sale price on each Business Day or, if there is no
                     such reported sale, at the most recently quoted bid price.
 
                           Shareholders who desire to redeem shares of the
                     Portfolio must place their redemption orders with the
                     Transfer Agent (or its authorized agent) prior to the
                     determination of net asset value and in accordance with the
                     procedures described below on any Business Day. The
                     redemption price is the net asset value per share of the
                     Portfolio next determined after receipt by the Transfer
                     Agent of the redemption order. Payment on redemption will
                     be made as promptly as possible and, in any event, within
                     five Business Days after the redemption order is received.
 
                           Purchase and redemption orders may be placed by
                     telephone. Neither the Trust nor the Transfer Agent will be
                     responsible for any loss, liability, cost or expense for
                     acting upon wire instructions or upon telephone
                     instructions that it reasonably believes to be genuine. The
                     Trust and the Transfer Agent will each employ reasonable
                     procedures to confirm that instructions communicated by
                     telephone are genuine, including requiring a form of
                     personal identification prior to acting upon instructions
                     received by telephone and recording telephone instructions.
 
                           If market conditions are extraordinarily active, or
                     other extraordinary circumstances exist, shareholders may
                     experience difficulties placing redemption orders by
                     telephone, and may wish to consider placing orders by other
                     means.
PERFORMANCE
          ______________________________________________________________________
 
                     From time to time, the Portfolio may advertise yield, tax
                     equivalent yield and total return. These figures will be
                     based on historical earnings and are not intended to
                     indicate future performance.
 
                           The yield of the Portfolio refers to the annualized
                     income generated by a hypothetical investment in the
                     Portfolio over a specified 30-day period. The yield is
                     calculated by assuming that the income generated by the
                     investment during that period generated each period over
                     one year and is shown as a percentage of the investment. A
                     tax equivalent yield is calculated by determining the rate
                     of return that would have been achieved on a fully taxable
                     investment to produce the after-tax equivalent of the
                     Portfolio's yield, assuming certain tax brackets for a
                     shareholder.
 
                           The total return of the Portfolio refers to the
                     average compounded rate of return to a hypothetical
                     investment for designated time periods (including, but not
                     limited to, the period from which the Portfolio commenced
                     operations through the specified date), assuming that the
                     entire investment is redeemed at the end of each period and
                     assuming the reinvestment of all dividend and capital gain
                     distributions.
 
                                                                              10
<PAGE>
                           The Portfolio may periodically compare its
                     performance to that of: (i) other mutual funds tracked by
                     mutual fund rating services (such as Lipper Analytical),
                     financial and business publications and periodicals; (ii)
                     broad groups of comparable mutual funds; (iii) unmanaged
                     indices which may assume investment of dividends but
                     generally do not reflect deductions for administrative and
                     management costs; or (iv) other investment alternatives.
                     The Portfolio may quote Morningstar, Inc., a service that
                     ranks mutual funds on the basis of risk-adjusted
                     performance, and Ibbotson Associates of Chicago, Illinois,
                     which provides historical returns of the capital markets in
                     the U.S. The Portfolio may use long-term performance of
                     these capital markets to demonstrate general long-term risk
                     versus reward scenarios and could include the value of a
                     hypothetical investment in any of the capital markets. The
                     Portfolio may also quote financial and business
                     publications and periodicals as they relate to fund
                     management, investment philosophy, and investment
                     techniques.
 
                           The Portfolio may quote various measures of
                     volatility and benchmark correlation in advertising and may
                     compare these measures to those of other funds. Measures of
                     volatility attempt to compare historical share price
                     fluctuations or total returns to a benchmark while measures
                     of benchmark correlation indicate how valid a comparative
                     benchmark might be. Measures of volatility and correlation
                     are calculated using averages of historical data and cannot
                     be calculated precisely.
TAXES
  ______________________________________________________________________________
 
                     The following summary of federal income tax consequences is
                     based on current tax laws and regulations, which may be
                     changed by legislative, judicial or administrative action.
                     No attempt has been made to present a detailed explanation
                     of the federal income tax treatment of the Portfolio or its
                     shareholders, and state and local tax consequences of an
                     investment in the Portfolio may differ from the federal
                     income tax consequences described below. Accordingly,
                     shareholders are urged to consult their tax advisers
                     regarding specific questions as to federal, state and local
                     income taxes. Additional information concerning taxes is
                     set forth in the Statement of Additional Information.
TAX STATUS OF THE
PORTFOLIO
                     The Portfolio is treated as a separate entity for federal
                     income tax purposes and is not combined with the Trust's
                     other portfolios. The Portfolio intends to continue to
                     qualify for the special tax treatment afforded regulated
                     investment companies under Subchapter M of the Internal
                     Revenue Code of 1986, as amended (the "Code"), so as to be
                     relieved of federal income tax on net investment company
                     taxable income) and net capital gain (the excess of net
                     long-term capital gain over net short-term capital loss)
                     distributed to shareholders.
TAX STATUS OF
DISTRIBUTIONS
                     The Portfolio intends to distribute substantially all of
                     its net investment income (including net short-term capital
                     gain) to shareholders. If, at the close of each quarter of
                     its taxable year, at least 50% of the value of the
                     Portfolio's total assets consists of obligations the
                     interest on which is excludable from gross income, the
                     Portfolio may pay "exempt-interest
 
                                                                              11

                     dividends" to its shareholders. Exempt-interest dividends
                     are excludable from a shareholder's gross income for
                     federal income tax purposes but may have certain collateral
                     federal tax consequences including alternative minimum tax
                     consequences. In addition, the receipt of exempt-interest
                     dividends may cause persons receiving Social Security or
                     Railroad Retirement benefits to be taxable on a portion of
                     such benefits. See the Statement of Additional Information.
 
                           Any dividends paid out of income realized by the
                     Portfolio on taxable securities will be taxable to
                     shareholders as ordinary income (whether received in cash
                     or in additional shares) to the extent of the Portfolio's
                     earnings and profits and will not qualify for the
                     dividends-received deduction for corporate shareholders.
                     Distributions to shareholders of net capital gains of the
                     Portfolio also will not qualify for the dividends received
                     deduction and will be taxable to shareholders as long-term
                     capital gain, whether received in cash or additional
                     shares, and regardless of how long a shareholder has held
                     the shares.
 
                           Dividends declared by the Portfolio in October,
                     November or December of any year and payable to
                     shareholders of record on a date in any such month will be
                     deemed to have been paid by the Portfolio and received by
                     the shareholders on December 31 of that year if paid by the
                     Portfolio at any time during the following January. The
                     Portfolio intends to make sufficient distributions prior to
                     the end of each calendar year to avoid liability for the
                     federal excise tax applicable to regulated investment
                     companies.
 
                           Interest on indebtedness incurred or continued by a
                     shareholder in order to purchase or carry shares of the
                     Portfolio is not deductible for federal income tax purposes
                     to the extent that it relates to exempt-interest dividends
                     distributed to the shareholder during the taxable year.
                     Furthermore, the Portfolio may not be an appropriate
                     investment for persons (including corporations and other
                     business entities) who are "substantial users" (or persons
                     related to "substantial users") of facilities financed by
                     industrial development bonds or private activity bonds.
                     Such persons should consult their tax advisers before
                     purchasing shares.
 
                           The Portfolio will report annually to its
                     shareholders the portion of dividends that is taxable and
                     the portion that is tax-exempt based on income received by
                     the Portfolio during the year to which the dividends
                     relate.
 
                           Each sale, exchange, or redemption of the Portfolio's
                     shares is a taxable transaction to the shareholder.
 
GENERAL INFORMATION
         _______________________________________________________________________
 
THE TRUST
                     The Trust was organized as a Massachusetts business trust
                     under a Declaration of Trust dated March 15, 1982. The
                     Declaration of Trust permits the Trust to offer separate
                     portfolios of shares and different classes of each
                     portfolio. In addition to the Portfolio, the Trust consists
                     of the following portfolios: Tax Free Portfolio,
                     Institutional Tax Free Portfolio, California Tax Exempt
                     Portfolio, Pennsylvania Municipal Portfolio, New York
                     Intermediate-
 
                                                                              12
<PAGE>
                     Term Municipal Portfolio, and Pennsylvania Tax Free
                     Portfolio. All consideration received by the Trust for
                     shares of any portfolio and all assets of such portfolio
                     belong to that portfolio and would be subject to
                     liabilities related thereto.
 
                           The Trust pays its expenses, including fees of its
                     service providers, audit and legal expenses, expenses of
                     preparing prospectuses, proxy solicitation materials and
                     reports to shareholders, costs of custodial services and
                     registering the shares under federal and state securities
                     laws, pricing, insurance expenses, litigation and other
                     extraordinary expenses, brokerage costs, interest charges,
                     taxes and organization expenses.
TRUSTEES OF THE TRUST
                     The management and affairs of the Trust are supervised by
                     the Trustees under the laws of the Commonwealth of
                     Massachusetts. The Trustees have approved contracts under
                     which, as described above, certain companies provide
                     essential management services to the Trust.
VOTING RIGHTS
                     Each share held entitles the shareholder of record to one
                     vote. The shareholders of each portfolio or class will vote
                     separately on matters relating solely to that portfolio or
                     class, such as any distribution plan. As a Massachusetts
                     business trust, the Trust is not required to hold annual
                     meetings of shareholders, but approval will be sought for
                     certain changes in the operation of the Trust and for the
                     election of Trustees under certain circumstances. In
                     addition, a Trustee may be removed by the remaining
                     Trustees or by shareholders at a special meeting called
                     upon written request of shareholders owning at least 10% of
                     the outstanding shares of the Trust. In the event that such
                     a meeting is requested, the Trust will provide appropriate
                     assistance and information to the shareholders requesting
                     the meeting.
REPORTING
                     The Trust issues unaudited financial statements
                     semi-annually and audited financial statements annually.
                     The Trust furnishes proxy statements and other reports to
                     shareholders of record.
SHAREHOLDER INQUIRIES
                     Shareholder inquiries should be directed to the Manager,
                     SEI Fund Management, Oaks, Pennsylvania, 19456.
DIVIDENDS
                     Substantially all of the net investment income (exclusive
                     of capital gains) of the Portfolio is declared daily and
                     paid monthly as a dividend. Shareholders of record on the
                     last record date of each period will be entitled to receive
                     the dividend distribution, which is generally paid on the
                     10th Business Day of the following month. If any net
                     capital gains are realized, they will be distributed by the
                     Portfolio annually.
 
                           Shareholders automatically receive all income
                     dividends and capital gain distributions in additional
                     shares at the net asset value next determined following the
                     record date, unless the shareholder has elected to take
                     such payment in cash. Shareholders may change their
                     election by providing written notice to the Manager at
                     least 15 days prior to the distribution.

DESCRIPTION OF
PERMITTED
INVESTMENTS AND RISK
FACTORS   ______________________________________________________________________
 
                     The following is a description of certain of the permitted
                     investments for the Portfolio, and the associated risk
                     factors:
MONEY MARKET SECURITIES
                     Money market securities are high-quality,
                     dollar-denominated, short-term debt instruments. They
                     consist of: (i) bankers' acceptances, certificates of
                     deposits, notes and time deposits of highly-rated U.S.
                     banks; (ii) U.S. Treasury obligations and obligations
                     issued by the agencies and instrumentalities of the U.S.
                     Government; and (iii) repurchase agreements involving any
                     of the foregoing obligations entered into with highly-rated
                     banks and broker-dealers.
MUNICIPAL SECURITIES
                     Municipal Securities consist of (i) debt obligations issued
                     by or on behalf of public authorities to obtain funds to be
                     used for various public facilities, for refunding
                     outstanding obligations, for general operating expenses and
                     for lending such funds to other public institutions and
                     facilities, and (ii) certain private activity and
                     industrial development bonds issued by or on behalf of
                     public authorities to obtain funds to provide for the
                     construction, equipment, repair or improvement of privately
                     operated facilities.
 
                           General obligation bonds are backed by the taxing
                     power of the issuing municipality. Revenue bonds are backed
                     by the revenues of a project or facility, tolls from a toll
                     bridge, for example. Certificates of participation
                     represent an interest in an underlying obligation or
                     commitment such as an obligation issued in connection with
                     a leasing arrangement. The payment of principal and
                     interest on private activity and industrial development
                     bonds generally is dependent solely on the ability of the
                     facility's user to meet its financial obligations and the
                     pledge, if any, of real and personal property so financed
                     as security for such payment.
 
                           Municipal notes include general obligation notes, tax
                     anticipation notes, revenue anticipation notes, bond
                     anticipation notes, certificates of indebtedness, demand
                     notes and construction loan notes and participation
                     interests in municipal notes. Municipal bonds include
                     general obligation bonds, revenue or special obligation
                     bonds, private activity and industrial development bonds
                     and participation interests in municipal bonds.
REPURCHASE AGREEMENTS
                     Repurchase agreements are arrangements by which the
                     Portfolio obtains a security and simultaneously commits to
                     return the security to the seller at an agreed upon price
 
                                                                              14
<PAGE>
                     (including principal and interest) on an agreed upon date
                     within a number of days from the date of purchase.
                     Repurchase agreements are considered loans under the 1940
                     Act.
STANDBY COMMITMENTS AND
PUTS
                     Securities subject to standby commitments or puts permit
                     the holder thereof to sell the securities at a fixed price
                     prior to maturity. Securities subject to a standby
                     commitment or put may be sold at any time at the current
                     market price. However, unless the standby commitment or put
                     was an integral part of the security as originally issued,
                     it may not be marketable or assignable; therefore, the
                     standby commitment or put would only have value to the
                     Portfolio owning the security to which it relates. In
                     certain cases, a premium may be paid for a standby
                     commitment or put, which premium will have the effect of
                     reducing the yield otherwise payable on the underlying
                     security. The Portfolio will limit standby commitment or
                     put transactions to institutions believed to present
                     minimal credit risks.
U.S. GOVERNMENT
OBLIGATIONS
                     Obligations issued by the U.S. Treasury or issued or
                     guaranteed by agencies of the U.S. Government, and
                     obligations issued or guaranteed by instrumentalities of
                     the U.S. Government. Some of these securities are supported
                     by the full faith and credit of the U.S. Treasury (e.g.,
                     Government National Mortgage Association securities),
                     others are supported by the right of the issuer to borrow
                     from the Treasury (e.g., Federal Farm Credit Bank
                     securities), while still others are supported only by the
                     credit of the instrumentality (e.g., Fannie Mae
                     securities).
VARIABLE AND FLOATING
RATE INSTRUMENTS
                     Certain of the obligations purchased by the Portfolio may
                     carry variable or floating rates of interest and may
                     involve a conditional or unconditional demand feature. Such
                     obligations may include variable amount master demand
                     notes. Such instruments bear interest at rates which are
                     not fixed, but which vary with changes in specified market
                     rates or indices. The interest rates on these securities
                     may be reset daily, weekly, quarterly or at some other
                     interval, and may have a floor or ceiling on interest rate
                     changes. There is a risk that the current interest rate on
                     such obligations may not accurately reflect existing market
                     interest rates. A demand instrument with a demand notice
                     period exceeding seven days may be considered illiquid if
                     there is no secondary market for such security.
WHEN-ISSUED AND DELAYED
DELIVERY SECURITIES
                     When-issued or delayed delivery transactions involve the
                     purchase of an instrument with payment and delivery taking
                     place in the future. Delivery of and payment for these
                     securities may occur a month or more after the date of the
                     purchase commitment. The Portfolio will maintain with the
                     custodian a separate account with liquid securities or cash
                     in an amount at least equal to these commitments. The
                     interest rate realized on these securities is fixed as of
                     the purchase date, and no interest accrues to the Portfolio
                     before settlement.
 
                                                                              15

This Prospectus sets forth concisely information about the above-referenced
Portfolios that an investor needs to know before investing. Please read this
Prospectus carefully, and keep it on file for future reference.
 
A Statement of Additional Information dated December 31, 1997, has been filed
with the Securities and Exchange Commission and is available upon request and
without charge by writing the Distributor, SEI Investments Distribution Co.,
Oaks, Pennsylvania 19456, or by calling 1-800-342-5734. The Statement of
Additional Information is incorporated into this Prospectus by reference.
 
SEI Tax Exempt Trust (the "Trust") is an open-end management investment company,
certain classes of which offer financial institutions a convenient means of
investing their own funds, or funds for which they act in a fiduciary, agency or
custodial capacity, in one or more professionally managed diversified and
non-diversified portfolios of securities. A portfolio may offer separate classes
of shares that differ from each other primarily in the allocation of certain
expenses and minimum investment amounts. This Prospectus offers Class A shares
of the Trust's Pennsylvania Municipal Portfolio (the "Fixed Income Portfolio"),
and Class A, Class B and Class C shares of the Trust's Pennsylvania Tax Free
Portfolio (the "Money Market Portfolio") (each a "Portfolio" and, together, the
"Portfolios").
 
AN INVESTMENT IN THE PENNSYLVANIA TAX FREE PORTFOLIO IS NEITHER INSURED NOR
GUARANTEED BY THE U.S. GOVERNMENT, AND THERE CAN BE NO ASSURANCE THAT THE
PORTFOLIO WILL BE ABLE TO MAINTAIN A STABLE NET ASSET VALUE OF $1.00 PER SHARE.
IN ADDITION, THE PENNSYLVANIA TAX FREE PORTFOLIO MAY INVEST A SIGNIFICANT
PERCENTAGE OF ITS ASSETS IN A SINGLE ISSUER, AND INVESTING IN THE PORTFOLIO MAY
BE RISKIER THAN INVESTING IN OTHER TYPES OF MONEY MARKET FUNDS.
 
- --------------------------------------------------------------------------------
 
 THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
 EXCHANGE COMMISSION, NOR HAS THE SECURITIES AND EXCHANGE COMMISSION PASSED
 UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE
 CONTRARY IS A CRIMINAL OFFENSE.
 
 THE TRUST'S SHARES ARE NOT DEPOSITS OR OBLIGATIONS OF, OR GUARANTEED OR
 ENDORSED BY, ANY BANK. THE SHARES ARE NOT FEDERALLY INSURED BY THE FEDERAL
 DEPOSIT INSURANCE CORPORATION, THE FEDERAL RESERVE BOARD OR ANY OTHER
 GOVERNMENT AGENCY. INVESTMENT IN THE SHARES INVOLVES RISK, INCLUDING POSSIBLE
 LOSS OF THE PRINCIPAL AMOUNT INVESTED.

OBJECTIVES AND
POLICIES
     ___________________________________________________________________________
PENNSYLVANIA
MUNICIPAL PORTFOLIO
                     The Fixed Income Portfolio's investment objective is to
                     provide current income exempt from both federal and
                     Pennsylvania state income taxes while preserving capital by
                     investing primarily in municipal securities within the
                     guidelines presented below.
 
                           The Fixed Income Portfolio has a fundamental policy,
                     under normal conditions, to be fully invested in
                     obligations which produce interest that is exempt from both
                     federal and Pennsylvania state income tax (state tax-free
                     obligations). Under normal circumstances, the Portfolio
                     will invest at least 90% (and intends to invest 100%) of
                     its net assets in securities the interest on which is not a
                     preference item for purposes of the federal alternative
                     minimum tax. In addition, for temporary defensive purposes
                     when, in the opinion of its investment adviser, such
                     securities are not readily available or of sufficient
                     quality, the Portfolio can invest up to 100% of its assets
                     in securities which pay interest which is exempt only from
                     federal income taxes or in taxable securities as described
                     below.
 
                           The Fixed Income Portfolio may purchase the following
                     types of municipal obligations, but only if such
                     securities, at the time of purchase, either have the
                     requisite rating or, if not rated, are of comparable
                     quality as determined by Morgan Grenfell Capital Management
                     Incorporated, the Portfolio's investment adviser ("Morgan
                     Grenfell"): (i) municipal bonds rated BBB or better by
                     Standard & Poor's Corporation ("S&P") or Baa or better by
                     Moody's Investors Service, Inc. ("Moody's"); (ii) municipal
                     notes rated at least SP-1 by S&P or MIG-1 or VMIG-1 by
                     Moody's; and (iii) tax-exempt commercial paper rated at
                     least A-1 by S&P or Prime-1 by Moody's. Bonds rated BBB by
                     S&P or Baa by Moody's have speculative characteristics.
                     Municipal obligations owned by the Fixed Income Portfolio
                     which become less than the prescribed investment quality
                     will be sold at a time when, in the judgment of Morgan
                     Grenfell, it does not substantially impact the market value
                     of the Portfolio.
 
                           The Fixed Income Portfolio will typically maintain a
                     dollar-weighted average portfolio maturity of seven years
                     or less. Each security purchased will typically have an
                     average maturity of no longer than fifteen years.
 
                                                                               4

PENNSYLVANIA TAX
FREE PORTFOLIO
                     The Money Market Portfolio's investment objective is a high
                     level of current income, free from federal income tax and,
                     to the extent possible, Pennsylvania personal income taxes,
                     consistent with preservation of capital. The Money Market
                     Portfolio will also attempt to maintain a constant net
                     asset value of $1.00 per share.
 
                           It is a fundamental policy of the Money Market
                     Portfolio to invest, under normal conditions, at least 80%
                     of its net assets in municipal securities the interest on
                     which, in the opinion of bond counsel for the issuer, is
                     exempt from federal income tax (collectively, "Municipal
                     Securities"). This Portfolio will, under normal conditions,
                     invest at least 80% of its net assets in securities the
                     interest on which is not a preference item for purposes of
                     the federal alternative minimum tax and invest at least 65%
                     of its total assets in municipal obligations the interest
                     on which is exempt from Pennsylvania personal income tax
                     ("Pennsylvania Securities"). Pennsylvania Securities
                     constitute municipal obligations of the Commonwealth of
                     Pennsylvania and its political subdivisions or municipal
                     authorities, as well as municipal obligations issued by
                     territories or possessions of the United States, such as
                     Puerto Rico. This Portfolio may invest, under normal
                     conditions, up to 20% of its net assets in (1) Municipal
                     Securities the interest on which is a preference item for
                     purposes of the federal alternative minimum tax (although
                     the Portfolio has no present intention of investing in such
                     securities), and (2) taxable securities, including shares
                     of other mutual funds to the extent permitted by
                     regulations of the SEC. In addition, for temporary
                     defensive purposes when its investment adviser determines
                     that market conditions warrant, the Money Market Portfolio
                     may invest up to 100% of its assets in municipal
                     obligations of states other than Pennsylvania or taxable
                     money market instruments.
 
                           The Money Market Portfolio may purchase municipal
                     bonds, municipal notes and tax-exempt commercial paper, but
                     only if such securities, at the time of purchase, meet the
                     quality, maturity and diversification requirements imposed
                     by Rule 2a-7. See "General Investment Policies."
 
                           There can be no assurance that either Portfolio will
                     be able to achieve its investment objective, or that the
                     Money Market Portfolio will be able to maintain a constant
                     $1.00 net asset value per share.
 
GENERAL INVESTMENT
POLICIES
     ___________________________________________________________________________
 
                     In purchasing obligations, the Money Market Portfolio
                     complies with the requirements of Rule 2a-7 under the
                     Investment Company Act of 1940 (the "1940 Act"), as that
                     Rule may be amended from time to time. These requirements
                     currently provide that the Money Market Portfolio must
                     limit its investments to securities with remaining
                     maturities of 397 days or less, and must maintain a
                     dollar-weighted average maturity of 90 days or less. In
                     addition, the Money Market Portfolio may only invest in
                     eligible securities. In general, this means securities
                     rated in one of the two highest categories for short-term
                     securities by at
 
                                                                               5
<PAGE>
                     least two nationally recognized statistical rating
                     organizations ("NRSROs") (or by one NRSRO if only one NRSRO
                     has rated the security), or, if unrated, determined by
                     Weiss, Peck & Greer, L.L.C. (the "Adviser") to be of
                     equivalent quality. Since the Portfolio often purchases
                     securities supported by credit enhancements from banks and
                     other financial institutions, changes in the credit quality
                     of these institutions could cause losses to the Portfolio
                     and affect its share price.
 
                           Securities rated in the highest rating category
                     (e.g., A-1 by S&P) by at least two NRSROs (or, if unrated,
                     determined by the Adviser to be of comparable quality) are
                     "first tier" securities. Non-first tier securities rated in
                     the second highest rating category (e.g., A-2 by S&P) by at
                     least one NRSRO (or, if unrated, determined by the Adviser
                     to be of comparable quality) are considered to be "second
                     tier" securities. The Portfolio's investments in non-first
                     tier conduit securities will be limited to 5% of the
                     Portfolio's assets. Conduit securities are securities
                     issued to finance non-governmental private projects, such
                     as housing developments and retirement homes, and for which
                     the ultimate obligor is not a governmental issuer.
 
                           Neither Portfolio will invest more than 25% of its
                     assets in Municipal Securities the interest on which is
                     derived from revenues of similar type projects. This
                     restriction does not apply to Municipal Securities in any
                     of the following categories: public housing authorities;
                     general obligations of states and localities; state and
                     local housing finance authorities; or municipal utilities
                     systems.
 
                           There could be economic, business, or political
                     developments which might affect all Municipal Securities of
                     a similar type. To the extent that a significant portion of
                     a Portfolio's assets are invested in Municipal Securities
                     payable from revenues on similar projects, the Portfolio
                     will be subject to the peculiar risks presented by such
                     projects to a greater extent than it would be if the
                     Portfolio's assets were not so invested. Moreover, in
                     seeking to attain its investment objective, a Portfolio may
                     invest all or any part of its assets in Municipal
                     Securities that are industrial development bonds.
 
                           Each Portfolio may invest in variable and floating
                     rate obligations, may purchase securities on a
                     "when-issued" basis, and reserves the right to engage in
                     transactions involving standby commitments. The Fixed
                     Income Portfolio may also purchase other types of
                     tax-exempt instruments as long as they are of a quality
                     equivalent to the long-term bond or commercial paper
                     ratings stated above. Although permitted to do so, the
                     Fixed Income Portfolio has no present intention to invest
                     in repurchase agreements. Each Portfolio will not invest
                     more than 10% of its net assets in illiquid securities.
 
                           For a description of the permitted investments and
                     ratings, see the "Description of Permitted Investments and
                     Risk Factors" and the Statement of Additional Information.

PENNSYLVANIA RISK
FACTORS
                     Under normal conditions the Fixed Income Portfolio will be
                     fully invested, and the Money Market Portfolio will invest
                     primarily, in obligations which produce interest income
                     exempt
 
                                                                               6
<PAGE>
                     from federal income tax and Pennsylvania state income tax.
                     Accordingly, each Portfolio will have considerable
                     investments in Pennsylvania municipal obligations. As a
                     result, each Portfolio will be more susceptible to factors
                     which adversely affect issuers of Pennsylvania obligations
                     than a mutual fund which does not have as great a
                     concentration in Pennsylvania municipal obligations.
 
                           An investment in either Portfolio will be affected by
                     the many factors that affect the financial condition of the
                     Commonwealth of Pennsylvania. For example, financial
                     difficulties of the Commonwealth, its counties,
                     municipalities and school districts that hinder efforts to
                     borrow and lower credit ratings are factors which may
                     affect the Portfolio. See "Special Considerations Relating
                     to Pennsylvania Municipal Securities" in the Statement of
                     Additional Information.
NON-DIVERSIFICATION
                     INVESTMENT IN THE MONEY MARKET PORTFOLIO, A NON-DIVERSIFIED
                     MUTUAL FUND, MAY ENTAIL GREATER RISK THAN WOULD INVESTMENT
                     IN MONEY MARKET FUNDS THAT ARE DIVERSIFIED ACROSS ISSUERS
                     LOCATED IN A NUMBER OF STATES BECAUSE OF ITS CONCENTRATION
                     IN MUNICIPAL SECURITIES OF A SINGLE STATE. Any economic,
                     political, or regulatory developments affecting the value
                     of the securities this Portfolio holds could have a greater
                     impact on the total value of the Portfolio's holdings than
                     would be the case if the portfolio securities were
                     diversified among more issuers. The Money Market Portfolio
                     intends to comply with the diversification requirements of
                     Subchapter M of the Internal Revenue Code of 1986, as
                     amended (the "Code"). In accordance with these
                     requirements, the Portfolio will not invest more than 5% of
                     its total assets in any one issuer; this limitation applies
                     to 50% of the Portfolio's total assets.
 
INVESTMENT
LIMITATIONS
        ________________________________________________________________________
 
                     The investment objectives and investment limitations are
                     fundamental policies of the Portfolios. Fundamental
                     policies cannot be changed with respect to the Trust or a
                     Portfolio without the consent of the holders of a majority
                     of the Trust's or that Portfolio's outstanding shares. It
                     is a fundamental policy of the Money Market Portfolio to
                     use its best efforts to maintain a constant net asset value
                     of $1.00 per share.
 
                     NEITHER PORTFOLIO MAY:
 
                     1. Purchase securities of any issuer (except securities
                        issued or guaranteed by the United States Government,
                        its agencies or instrumentalities) if, as a result, more
                        than 5% of the total assets of the Portfolio would be
                        invested in the securities of such issuer. This
                        limitation does not apply to the Money Market Portfolio
                        to the extent permitted by Rule 2a-7.
 
                     2. Purchase any securities which would cause more than 25%
                        of the total assets of the Portfolio, based on current

THE MANAGER
          ______________________________________________________________________

                     Agent") provides the Trust with overall management
                     services, regulatory reporting, all necessary office space,
                     equipment, personnel and facilities, and serves as
                     institutional transfer agent and dividend disbursing agent.
 
                           For these services, the Manager is entitled to a fee,
                     which is calculated daily and paid monthly, at an annual

                     Income Portfolio and .36% of the average daily net assets
                     of the Money Market Portfolio. The Manager has voluntarily
                     waived a portion of its fees in order to limit the total
                     operating expenses of the Fixed Income Portfolio to not
                     more than .48% of that Portfolio's average daily net assets
                     on an annualized basis, and of Class A shares of the Money
                     Market Portfolio to not more than .35% of that Portfolio's
                     average daily net assets on an annualized basis. The
                     Manager reserves the right, in its sole discretion, to
                     terminate these voluntary fee waivers at any time. For the
                     fiscal year ended August 31, 1997, the Fixed Income and
                     Money Market Portfolios paid management fees, after
                     waivers, of .21% and .25%, respectively, of their average
                     daily net assets.

DISTRIBUTION AND
SHAREHOLDER
SERVICING
      __________________________________________________________________________
 
                     SEI Investments Distribution Co. (the "Distributor"), a
                     wholly owned subsidiary of SEI Investments Company ("SEI
                     Investments"), serves as each Portfolio's distributor
                     pursuant to a distribution agreement (the "Distribution
                     Agreement") with the Trust.
 
                           The Portfolios have adopted plans under which firms,
                     including the Distributor, that provide shareholder and
                     administrative services may receive compensation therefor.
                     The Class A, B and C plans differ in a number of ways,
                     including the amounts that may be paid. Under each plan,
                     the Distributor may provide those services itself or may
                     enter into arrangements under which third parties provide
                     such services and are compensated by the Distributor. Under
                     such arrangements the Distributor may retain as a profit
                     any difference
 
                                                                               9

                     between the fee it receives and the amount it pays such
                     third party. In addition, the Portfolios may enter into
                     such arrangements directly.
 
                           Under the Class A plan, the Distributor is entitled
                     to receive a fee at an annual rate of up to .25% of the
                     average daily net assets of such Portfolio attributable to
                     Class A shares, in return for provision of a broad range of
                     shareholder services. Under the Class B and Class C
                     shareholder service plans, the Distributor is entitled to
                     receive shareholder service fees to the Distributor at an
                     annual rate of up to .25% of average daily net assets in
                     exchange for the Distributor's (or its agent's) efforts in
                     maintaining client accounts; arranging for bank wires;
                     responding to client inquiries concerning services provided
                     or investment; and assisting clients in changing dividend
                     options, account designations and addresses. In addition,
                     under their administrative services plans, Class B and
                     Class C shares will pay the Distributor administrative
                     services fees at specified percentages of the average daily
                     net assets of the shares of the Class (up to .05% in the
                     case of the Class B shares and up to .25% in the case of
                     the Class C shares). Administrative services include sub-
                     accounting; providing information on share positions to
                     clients; forwarding shareholder communications to clients;
                     processing purchase, exchange and redemption orders; and
                     processing dividend payments.
 
                           It is possible that an institution may offer
                     different classes of shares to its customers and differing
                     services to the Classes of each Portfolio and thus receive
                     compensation with respect to different classes. These
                     financial institutions may also charge separate fees to
                     their customers.
 
                           The Trust may execute brokerage or other agency
                     transactions through the Distributor for which the
                     Distributor may receive compensation.
 
                           The Distributor may, from time to time and at its own
                     expense, provide promotional incentives, in the form of
                     cash or other compensation to certain financial
                     institutions whose representatives have sold or are
                     expected to sell significant amounts of the Portfolio's
                     shares.
 
PURCHASE AND
REDEMPTION OF SHARES
    ____________________________________________________________________________
 
                     Financial institutions may acquire shares of each Portfolio
                     for their own account, or as a record owner on behalf of
                     fiduciary, agency or custody accounts, by placing orders
                     with the Transfer Agent (or its authorized agent).
                     Institutions that use certain SEI proprietary systems may
                     place orders electronically through those systems.
                     Financial institutions which purchase shares for the
                     accounts of their customers may impose separate charges on
                     these customers for account services. Financial
                     institutions may impose an earlier cut-off time for receipt
                     of purchase orders directed through them to allow for
                     processing and transmittal of these orders to the Transfer
                     Agent for effectiveness on the same day.
 
                                                                              10
<PAGE>
                           Shares of each Portfolio may be purchased or redeemed
                     on days on which the New York Stock Exchange is open for
                     business ("Business Days"). However, Money Market portfolio
                     shares cannot be purchased by Federal Reserve wire on
                     federal holidays restricting wire transfers.
 
                           Shareholders who desire to purchase shares for cash
                     must place their orders with the Transfer Agent (or its
                     authorized agent) prior to the determination of net asset
                     value and in accordance with the procedures described below
                     for the order to be accepted on that Business Day; the
                     specified time is presently 2:00 p.m., Eastern time, for
                     the Money Market Portfolio and the close of trading on the
                     New York Stock Exchange (presently 4:00 p.m., Eastern time)
                     for the Fixed Income Portfolio. Cash investments must be
                     transmitted or delivered in federal funds to the wire agent
                     by the close of business on the same day the order is
                     placed for the Money Market Portfolio and on the next
                     Business Day following the day the order is placed for the
                     Fixed Income Portfolio.
 
                           Purchases will be made in full or fractional shares
                     of the Fixed Income Portfolio calculated to three decimal
                     places. The Trust will send shareholders a statement of
                     shares owned after each transaction. The purchase price of
                     shares is the net asset value next determined after a
                     purchase order is received and accepted by the Trust. The
                     purchase price of shares of the Money Market Portfolio is
                     expected to remain constant at $1.00. The net asset value
                     per share of each Portfolio is determined by dividing the
                     total value of its investments and other assets, less any
                     liabilities, by the total number of outstanding shares of
                     the Portfolio. The Money Market Portfolio's investments
                     will be valued by the amortized cost method described in
                     the Statement of Additional Information. Net asset value
                     per share is determined on each Business Day as of 2:00
                     p.m., Eastern time, for the Money Market Portfolio, and as
                     of the close of trading on the New York Stock Exchange
                     (presently 4:00 p.m., Eastern time) for the Fixed Income
                     Portfolio.
 
                           Information about the market value of each portfolio
                     security of the Fixed Income Portfolio may be obtained by
                     the Manager from an independent pricing service. Securities
                     having maturities of 60 days or less at the time of
                     purchase will be valued using the amortized cost method
                     (described in the Statement of Additional Information),
                     which approximates the securities' market value. The
                     pricing service may use a matrix system to determine
                     valuations of equity and fixed income securities. This
                     system considers such factors as security prices, yields,
                     maturities, call features, ratings and developments
                     relating to specific securities in arriving at valuations.
                     The pricing service may also provide market quotations. The
                     procedures used by the pricing service and its valuations
                     are reviewed by the officers of the Trust under the general
                     supervision of the Trustees. Portfolio securities for which
                     market quotations are available are valued at the last
                     quoted sale price on each Business Day or, if there is no
                     such reported sale, at the most recently quoted bid price.
 
                                                                              11
<PAGE>
                           Shareholders who desire to redeem shares of a
                     Portfolio must place their redemption orders with the
                     Transfer Agent (or its authorized agent) prior to the
                     determination of net asset value and in accordance with the
                     procedures described below on any Business Day. Otherwise,
                     the redemption orders will be effective on the next
                     Business Day. Payment for redemption orders from the Fixed
                     Income Portfolio will be made as promptly as possible and,
                     in any event, within five Business Days after the
                     redemption order is received. Payment for redemption orders
                     from the Money Market Portfolio received before the
                     calculation of net asset value will be made the same day by
                     transfer of federal funds. The redemption price is the net
                     asset value per share of the Portfolio next determined
                     after receipt by the Transfer Agent of an effective
                     redemption order. Financial institutions which redeem
                     shares for the accounts of their customers may impose their
                     own procedures and cut-off times for receipt of redemption
                     requests directed through the financial institution.
 
                           Purchase and redemption orders may be placed by
                     telephone. Neither the Trust nor the Transfer Agent will be
                     responsible for any loss, liability, cost or expense for
                     acting upon wire instructions or upon telephone
                     instructions that it reasonably believes to be genuine. The
                     Trust and the Transfer Agent will each employ reasonable
                     procedures to confirm that instructions communicated by
                     telephone are genuine, including requiring a form of
                     personal identification prior to acting upon instructions
                     received by telephone and recording telephone instructions.
 
                           If market conditions are extraordinarily active, or
                     other extraordinary circumstances exist, shareholders may
                     experience difficulties placing redemption orders by
                     telephone, and may wish to consider placing orders by other
                     means.
PERFORMANCE
          ______________________________________________________________________
 
                     From time to time, the Money Market Portfolio may advertise
                     its "current yield" and "effective yield," and the Fixed
                     Income Portfolio may advertise its yield and total return.
                     Each Portfolio may also advertise a "tax equivalent yield."
                     These figures are based on historical earnings and are not
                     intended to indicate future performance.
 
                           The "current yield" of the Money Market Portfolio
                     refers to the income generated by an investment over a
                     seven-day period which 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 is assumed
                     to be reinvested. The effective yield will be slightly
                     higher than the "current yield" because of the compounding
                     effect of this assumed reinvestment.
 
                           The yield of the Fixed Income Portfolio refers to the
                     annualized income generated by a hypothetical investment,
                     in the Portfolio over a specified 30-day period. The yield
                     is calculated by assuming that the income generated by the
                     investment during that period generated each period over
                     one year and is shown as a percentage of the investment.
 
                                                                              12
<PAGE>
                           The total return of the Fixed Income Portfolio refers
                     to the average compounded rate of return to a hypothetical
                     investment for designated time periods (including, but not
                     limited to, the period from which the Portfolio commenced
                     operations through the specified date), assuming that the
                     entire investment is redeemed at the end of each period and
                     assuming the reinvestment of all dividend and capital gain
                     distributions.
 
                           The "tax equivalent yield" is calculated by
                     determining the rate of return that would have been
                     achieved on a fully taxable investment to produce the
                     after-tax equivalent of a Portfolio's yield, assuming
                     certain tax brackets for a shareholder.
 
                           A Portfolio may periodically compare its performance
                     to that of: (i) other mutual funds tracked by mutual fund
                     rating services (such as Lipper Analytical), financial and
                     business publications and periodicals; (ii) broad groups of
                     comparable mutual funds; (iii) unmanaged indices which may
                     assume investment of dividends but generally do not reflect
                     deductions for administrative and management costs; or (iv)
                     other investment alternatives. The Fixed Income Portfolio
                     may quote Morningstar, Inc., a service that ranks mutual
                     funds on the basis of risk-adjusted performance, and
                     Ibbotson Associates of Chicago, Illinois, which provides
                     historical returns of the capital markets in the U.S. The
                     Fixed Income Portfolio may use long-term performance of
                     these capital markets to demonstrate general long-term risk
                     versus reward scenarios and could include the value of a
                     hypothetical investment in any of the capital markets. The
                     Fixed Income Portfolio may also quote financial and
                     business publications and periodicals as they relate to
                     fund management, investment philosophy, and investment
                     techniques.
 
                           The Fixed Income Portfolio may quote various measures
                     of volatility and benchmark correlation in advertising and
                     may compare these measures to those of other funds.
                     Measures of volatility attempt to compare historical share
                     price fluctuations or total returns to a benchmark while
                     measures of benchmark correlation indicate how valid a
                     comparative benchmark might be. Measures of volatility and
                     correlation are calculated using averages of historical
                     data and cannot be calculated precisely.
 
                           The performance of Class A shares of the Money Market
                     Portfolio will normally be higher than that of Class B or
                     Class C shares of the Portfolio because of the additional
                     administrative services expenses charged to Class B or
                     Class C shares.
TAXES
  ______________________________________________________________________________
 
                     The following summary of federal and state income tax
                     consequences is based on current tax laws and regulations,
                     which may be changed by legislative, judicial or
                     administrative action. No attempt has been made to present
                     a detailed explanation of the federal, state or local
                     income tax treatment of the Portfolio or its shareholders.
                     Accordingly, shareholders are urged to consult their tax
                     advisers regarding specific questions as to federal, state
                     and local income taxes. Additional information concerning
                     taxes is set forth in the Statement of Additional
                     Information.
 
                                                                              13
<PAGE>
TAX STATUS OF EACH
PORTFOLIO
                     Each Portfolio is treated as a separate entity for federal
                     income tax purposes and is not combined with the Trust's
                     other portfolios. Each Portfolio intends to continue to
                     qualify for the special tax treatment afforded regulated
                     investment companies under Subchapter M of the Internal
                     Revenue Code of 1986, as amended (the "Code"), so as to be
                     relieved of federal income tax on net investment company
                     taxable income and net capital gain (the excess of net
                     long-term capital gain over net short-term capital loss)
                     distributed to shareholders.
TAX STATUS OF
DISTRIBUTIONS
                     Each Portfolio intends to distribute substantially all of
                     its net investment income (including net short-term capital
                     gain) to shareholders. If, at the close of each quarter of
                     its taxable year, at least 50% of the value of a
                     Portfolio's total assets consists of obligations the
                     interest on which is excludable from gross income, the
                     Portfolio may pay "exempt-interest dividends" to its
                     shareholders. Exempt-interest dividends are excludable from
                     a shareholder's gross income for federal income tax
                     purposes but may have certain collateral federal tax
                     consequences including alternative minimum tax
                     consequences. In addition, the receipt of exempt-interest
                     dividends may cause persons receiving Social Security or
                     Railroad Retirement benefits to be taxable on a portion of
                     such benefits. See the Statement of Additional Information.
 
                           Any dividends paid out of income realized by a
                     Portfolio on taxable securities will be taxable to
                     shareholders as ordinary income (whether received in cash
                     or in additional shares) to the extent of such Portfolio's
                     earnings and profits and will not qualify for the
                     dividends-received deduction for corporate shareholders.
                     Distributions to shareholders of net capital gains of a
                     Portfolio also will not qualify for the dividends received
                     deduction and will be taxable to shareholders as long-term
                     capital gain, whether received in cash or additional
                     shares, and regardless of how long a shareholder has held
                     the shares.
 
                           Dividends declared by a Portfolio in October,
                     November or December of any year and payable to
                     shareholders of record on a date in any such month will be
                     deemed to have been paid by the Portfolio and received by
                     the shareholders on December 31 of that year if paid by the
                     Portfolio at any time during the following January. Each
                     Portfolio intends to make sufficient distributions prior to
                     the end of each calendar year to avoid liability for the
                     federal excise tax applicable to regulated investment
                     companies.
 
                           Interest on indebtedness incurred or continued by a
                     shareholder in order to purchase or carry shares of a
                     Portfolio is not deductible for federal income tax purposes
                     to the extent that it relates to exempt-interest dividends
                     distributed to the shareholder during the taxable year.
                     Furthermore, the Portfolios may not be an appropriate
                     investment for persons (including corporations and other
                     business entities) who are "substantial users" (or persons
                     related to "substantial users") of facilities financed by
                     industrial development bonds or private activity bonds.
                     Such persons should consult their tax advisers before
                     purchasing shares.
 
                                                                              14
<PAGE>
                           Each Portfolio will report annually to its
                     shareholders the portion of dividends that is taxable and
                     the portion that is tax-exempt based on income received by
                     the Portfolio during the year to which the dividends
                     relate.
 
                           Each sale, exchange or redemption of the Portfolios'
                     shares is a taxable transaction to the shareholders.
PENNSYLVANIA TAXES
                     The following is a general, abbreviated summary of certain
                     of the provisions of the Pennsylvania tax code presently in
                     effect as they directly govern the taxation of shareholders
                     subject to Pennsylvania personal income tax. These
                     provisions are subject to change by legislative or
                     administrative action, and any such change may be
                     retroactive.
 
                           Distributions paid by the Portfolios to shareholders
                     will not be subject to the Pennsylvania personal income tax
                     or to the Philadelphia School District investment net
                     income tax to the extent that the distributions are
                     attributable to interest received by the Portfolio from its
                     investments in (i) obligations issued by the Commonwealth
                     of Pennsylvania, any public authority, commission, board of
                     agency created by the Commonwealth of Pennsylvania or any
                     public authority created by such political subdivision, and
                     (ii) obligations of the United States, the interest and
                     gains from which are statutorily free from state taxation
                     in the Commonwealth. Distributions by the Portfolios to a
                     Pennsylvania resident that are attributable to most other
                     sources will not be exempt from the Pennsylvania personal
                     income tax or (for residents of Philadelphia) the
                     Philadelphia School District investment net income tax.
                     Distributions paid by a Portfolio which are excludable as
                     exempt income for federal tax purposes are not subject to
                     the Pennsylvania corporate net income tax.
 
                           Each Portfolio intends to invest primarily in
                     obligations that produce interest exempt from federal and
                     Pennsylvania taxes. If the Portfolios invest in obligations
                     that pay interest that is not exempt for Pennsylvania
                     purposes but is exempt for federal purposes, a portion of
                     the Portfolios' distributions will be subject to
                     Pennsylvania personal income tax.
 
GENERAL INFORMATION
         _______________________________________________________________________
 
THE TRUST
                     The Trust was organized as a Massachusetts business trust
                     under a Declaration of Trust dated March 15, 1982. The
                     Declaration of Trust permits the Trust to offer separate
                     portfolios of shares and different classes of each
                     portfolio. In addition to the Portfolios, the Trust
                     consists of the following portfolios: Tax Free Portfolio,
                     Institutional Tax Free Portfolio, California Tax Exempt
                     Portfolio, Intermediate-Term Municipal Portfolio, and New
                     York Intermediate-Term Municipal Portfolio. All
                     consideration received by the Trust for shares of any
                     portfolio and all assets of such portfolio belong to that
                     portfolio and would be subject to liabilities related
                     thereto.
 
                           The Trust pays its expenses, including fees of its
                     service providers, audit and legal expenses, expenses of
                     preparing prospectuses, proxy solicitation materials and
                     reports to shareholders, costs of custodial services and
                     registering the shares under federal and state
 
                                                                              15
<PAGE>
                     securities laws, pricing, insurance expenses, litigation
                     and other extraordinary expenses, brokerage costs, interest
                     charges, taxes and organization expenses.
TRUSTEES OF THE TRUST
                     The management and affairs of the Trust are supervised by
                     the Trustees under the laws of the Commonwealth of
                     Massachusetts. The Trustees have approved contracts under
                     which, as described above, certain companies provide
                     essential services to the Trust.
VOTING RIGHTS
                     Each share held entitles the shareholder of record to one
                     vote. The shareholders of each portfolio or class will vote
                     separately on matters relating solely to that portfolio or
                     class, such as any distribution plan. As a Massachusetts
                     business trust, the Trust is not required to hold annual
                     meetings of shareholders, but approval will be sought for
                     certain changes in the operation of the Trust and for the
                     election of Trustees under certain circumstances. In
                     addition, a Trustee may be removed by the remaining
                     Trustees or by shareholders at a special meeting called
                     upon written request of shareholders owning at least 10% of
                     the outstanding shares of the Trust. In the event that such
                     a meeting is requested, the Trust will provide appropriate
                     assistance and information to the shareholders requesting
                     the meeting.
REPORTING
                     The Trust issues unaudited financial statements
                     semi-annually and audited financial statements annually.
                     The Trust furnishes proxy statements and other reports to
                     shareholders of record.
SHAREHOLDER INQUIRIES
                     Shareholder inquiries should be directed to the Manager,
                     SEI Fund Management, Oaks, Pennsylvania, 19456.
DIVIDENDS
                     The net investment income (exclusive of capital gains) of
                     each Portfolio is distributed in the form of dividends. The
                     Money Market Portfolio declares dividends daily, and
                     shareholders of record at the close of each Business Day
                     will be entitled to receive that day's dividend. The Money
                     Market Portfolio pays dividends on the first Business Day
                     of each month. Dividends will be paid on the next Business
                     Day to shareholders who redeem all of their shares of the
                     Money Market Portfolio at any time during the month.
 
                           The Fixed Income Portfolio declares dividends daily,
                     and shareholders of record on the last record date of each
                     period will be entitled to receive the periodic dividend
                     distribution, which is generally paid on the 10th Business
                     Day of the following month. If any net capital gains are
                     realized by either Portfolio, they will be distributed
                     annually. Shareholders automatically receive all income
                     dividends and capital gain distributions in additional
                     shares, unless the shareholder has elected to take such
                     payment in cash. Shareholders may change their election by
                     providing written notice to the Manager at least 15 days
                     prior to the distribution.

DESCRIPTION OF
PERMITTED
INVESTMENTS AND RISK
FACTORS   ______________________________________________________________________
 
                     The following is a description of certain of the permitted
                     investments for the Portfolios, and the associated risk
                     factors:
MONEY MARKET SECURITIES
                     Money market securities are high-quality,
                     dollar-denominated, short-term debt instruments. They
                     consist of: (i) bankers' acceptances, certificates of
                     deposits, notes and time deposits of highly-rated U.S.
                     banks; (ii) U.S. Treasury obligations and obligations
                     issued by the agencies and instrumentalities of the U.S.
                     Government; and (iii) repurchase agreements involving any
                     of the foregoing obligations entered into with highly-rated
                     banks and broker-dealers.
MUNICIPAL SECURITIES
                     Municipal Securities consist of (i) debt obligations issued
                     by or on behalf of public authorities to obtain funds to be
                     used for various public facilities, for refunding
                     outstanding obligations, for general operating expenses and
                     for lending such funds to other public institutions and
                     facilities, and (ii) certain private activity and
                     industrial development bonds issued by or on behalf of
                     public authorities to obtain funds to provide for the
                     construction, equipment, repair or improvement of privately
                     operated facilities.
 
                           General obligation bonds are backed by the taxing
                     power of the issuing municipality. Revenue bonds are backed
                     by the revenues of a project or facility, tolls from a toll
                     bridge, for example. Certificates of participation
                     represent an interest in an underlying obligation or
                     commitment such as an obligation issued in connection with
                     a leasing arrangement. The payment of principal and
                     interest on private activity and industrial development
                     bonds generally is dependent solely on the ability of the
                     facility's user to meet its financial obligations and the
                     pledge, if any, of real and personal property so financed
                     as security for such payment.
 
                           Municipal notes include general obligation notes, tax
                     anticipation notes, revenue anticipation notes, bond
                     anticipation notes, certificates of indebtedness, demand
                     notes and construction loan notes and participation
                     interests in municipal notes. Municipal bonds include
                     general obligation bonds, revenue or special obligation
                     bonds, private activity and industrial development bonds
                     and participation interests in municipal bonds.
REPURCHASE AGREEMENTS
                     Repurchase agreements are arrangements by which a Portfolio
                     obtains a security and simultaneously commits to return the
                     security to the seller at an agreed upon price (including
                     principal and interest) on an agreed upon date within a
                     number of days from the date of purchase. Repurchase
                     agreements are considered loans under the 1940 act.
STANDBY COMMITMENTS AND
PUTS
                     Securities subject to standby commitments or puts permit
                     the holder thereof to sell the securities at a fixed price
                     prior to maturity. Securities subject to a standby
                     commitment or put may be sold at any time at the current
                     market price. However, unless the standby
 
                                                                              17
<PAGE>
                     commitment or put was an integral part of the security as
                     originally issued, it may not be marketable or assignable;
                     therefore, the standby commitment or put would only have
                     value to the Portfolio owning the security to which it
                     relates. In certain cases, a premium may be paid for a
                     standby commitment or put, which premium will have the
                     effect of reducing the yield otherwise payable on the
                     underlying security. The Portfolio will limit standby
                     commitment or put transactions to institutions believed to
                     present minimal credit risks.
U.S. GOVERNMENT
OBLIGATIONS
                     Obligations issued by the U.S. Treasury or issued or
                     guaranteed by agencies of the U.S. Government and
                     obligations issued or guaranteed by instrumentalities of
                     the U.S. Government. Some of these securities are supported
                     by the full faith and credit of the U.S. Treasury (e.g.,
                     Government National Mortgage Association securities),
                     others are supported by the right of the issuer to borrow
                     from the Treasury (e.g., Federal Farm Credit Bank
                     securities), while still others are supported only by the
                     credit of the instrumentality (e.g. Fannie Mae securities).
VARIABLE AND FLOATING
RATE INSTRUMENTS
                     Certain of the obligations purchased by a Portfolio may
                     carry variable or floating rates of interest and may
                     involve a conditional or unconditional demand feature. Such
                     obligations may include variable amount master demand
                     notes. Such instruments bear interest at rates which are
                     not fixed, but which vary with changes in specified market
                     rates or indices. The interest rates on these securities
                     may be reset daily, weekly, quarterly or at some other
                     interval, and may have a floor or ceiling on interest rate
                     changes. There is a risk that the current interest rate on
                     such obligations may not accurately reflect existing market
                     interest rates. A demand instrument with a demand notice
                     period exceeding seven days may be considered illiquid if
                     there is no secondary market for such security.
WHEN-ISSUED AND DELAYED
DELIVERY SECURITIES
                     When-issued or delayed delivery transactions involve the
                     purchase of an instrument with payment and delivery taking
                     place in the future. Delivery of and payment for these
                     securities may occur a month or more after the date of the
                     purchase commitment. Each Portfolio will maintain with the
                     custodian a separate account with liquid securities or cash
                     in an amount at least equal to these commitments. The
                     interest rate realized on these securities is fixed as of
                     the purchase date, and no interest accrues to a Portfolio
                     before settlement.
 
                                                                              18

CALIFORNIA TAX EXEMPT PORTFOLIO
 
- --------------------------------------------------------------------------------
 
This Prospectus sets forth concisely information about the above-referenced
Portfolio that an investor needs to know before investing. Please read this
Prospectus carefully, and keep it on file for future reference.
 
A Statement of Additional Information dated December 31, 1997, has been filed
with the Securities and Exchange Commission, and is available upon request and
without charge by writing the Distributor, SEI Investments Distribution Co.,
Oaks, Pennsylvania 19456, or by calling 1-800-342-5734. The Statement of
Additional Information is incorporated into this Prospectus by reference.
 
SEI Tax Exempt Trust (the "Trust") is an open-end investment management company,
certain classes of which offer financial institutions a convenient means of
investing their own funds, or funds for which they act in a fiduciary, agency or
custodial capacity, in one or more professionally managed diversified and
non-diversified portfolios of securities. A portfolio may offer separate classes
of shares that differ from each other primarily in the allocation of certain
expenses and minimum investment amounts. This Prospectus offers CNI Class shares
of the Trust's California Tax Exempt Portfolio (the "Portfolio"), a money market
portfolio.
 
AN INVESTMENT IN THE PORTFOLIO IS NEITHER INSURED NOR GUARANTEED BY THE U.S.
GOVERNMENT, AND THERE CAN BE NO ASSURANCE THAT THE PORTFOLIO WILL BE ABLE TO
MAINTAIN A STABLE NET ASSET VALUE OF $1.00 PER SHARE. IN ADDITION, THE PORTFOLIO
MAY INVEST A SIGNIFICANT PERCENTAGE OF ITS ASSETS IN A SINGLE ISSUER, AND
INVESTING IN THE PORTFOLIO MAY BE RISKIER THAN INVESTING IN OTHER TYPES OF MONEY
MARKET FUNDS.
 
- --------------------------------------------------------------------------------
 
 THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
 EXCHANGE COMMISSION, NOR HAS THE SECURITIES AND EXCHANGE COMMISSION PASSED
 UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE
 CONTRARY IS A CRIMINAL OFFENSE.
 
 THE TRUST'S SHARES ARE NOT DEPOSITS OR OBLIGATIONS OF, OR GUARANTEED OR
 ENDORSED BY, ANY BANK. THE SHARES ARE NOT FEDERALLY INSURED BY THE FEDERAL
 DEPOSIT INSURANCE CORPORATION, THE FEDERAL RESERVE BOARD OR ANY OTHER
 GOVERNMENT AGENCY. INVESTMENT IN THE SHARES INVOLVES RISK, INCLUDING POSSIBLE
 LOSS OF THE PRINCIPAL AMOUNT INVESTED.

INVESTMENT OBJECTIVE
AND POLICIES
     ___________________________________________________________________________
 
                     The Portfolio's investment objective is to preserve
                     principal value and maintain a high degree of liquidity
                     while providing current income exempt from federal and, to
                     the extent possible, California state personal income
                     taxes. There can be no assurance that the Portfolio will
                     achieve its investment objective.
 
                           It is a fundamental policy of the Portfolio to
                     invest, under normal conditions, at least 80% of its net
                     assets in municipal securities that produce interest that,
                     in the opinion of bond counsel for the issuers, is exempt
                     from federal income tax (collectively, "Municipal
                     Securities"), and the Portfolio will invest, under normal
                     conditions, at least 80% of its net assets in securities
                     the interest on which is not a preference item for purposes
                     of the federal alternative minimum tax. Under normal
                     conditions, at least 65% of the Portfolio's assets will be
                     invested in municipal obligations the interest on which is
                     exempt from California state personal income tax. These
                     constitute municipal obligations of the state of California
                     and its political subdivisions or municipal authorities, as
                     well as municipal obligations issued by territories or
                     possessions of the United States.
 
                           Under normal conditions, the Portfolio may invest, in
                     the aggregate; up to 20% of its net assets in (1) Municipal
                     Securities the interest on which is a preference item for
                     purposes of the federal alternative minimum tax (although
                     the Portfolio has no present intention of investing in such
                     securities) and (2) taxable investments. In addition, for
                     temporary defensive purposes when Weiss, Peck & Greer,
                     L.L.C., the Portfolio's investment adviser (the "Adviser"),
                     determines that market conditions warrant, the Portfolio
                     may invest up to 100% of its assets in municipal
                     obligations of states other than California or in taxable
                     money market securities.
 
                           The Adviser will not invest more than 25% of the
                     Portfolio's assets in Municipal Securities the interest on
                     which is derived from revenues of similar type projects.
                     This restriction does not apply to municipal securities in
                     any of the following categories: public housing
                     authorities; general obligations of states and localities;
                     state and local housing finance authorities or municipal
                     utilities systems.
 
                                                                               4

GENERAL INVESTMENT
POLICIES
     ___________________________________________________________________________
 
                     In purchasing obligations, the Portfolio complies with the
                     requirements of Rule 2a-7 under the Investment Company Act
                     of 1940 (the "1940 Act"), as that Rule may be amended from
                     time to time. These requirements currently provide that the
                     Portfolio must limit its investments to securities with
                     remaining maturities of 397 days or less, and must maintain
                     a dollar-weighted average maturity of 90 days or less. In
                     addition, the Portfolio may only invest in eligible quality
                     securities. In general, this means securities rated in one
                     of the two highest categories for short-term securities by
                     at least two nationally recognized statistical rating
                     organizations ("NRSROs") (or by one NRSRO if only one NRSRO
                     has rated the security), or, if unrated, determined by the
                     Adviser to be of equivalent quality. Since the Portfolio
                     often purchases securities supported by credit enhancements
                     from banks and other financial institutions, changes in the
                     credit quality of these institutions could cause losses to
                     the Portfolio and affect its share price.
 
                           Securities rated in the highest rating category
                     (E.G., A-1 by Standard & Poor's Corporation ("S&P")) by at
                     least two NRSROs (or, if unrated, determined by the Adviser
                     to be of comparable quality) are "first tier" securities.
                     Non-first tier securities rated in the second highest
                     rating category (E.G., A-2 by S&P) by at least one NRSRO
                     (or, if unrated, determined by the Adviser to be of
                     comparable quality) are considered to be "second tier"
                     securities. The Portfolio's investments in non-first tier
                     conduit securities will be limited to 5% of the Portfolio's
                     assets. Conduit securities are securities issued to finance
                     non-governmental private projects, such as housing
                     developments and retirement homes, and for which the
                     ultimate obligor is not a governmental issuer.
 
                           The Portfolio may purchase municipal bonds, municipal
                     notes and tax-exempt commercial paper, but only if such
                     securities, at the time of purchase, either meet the rating
                     requirements imposed by Rule 2a-7 or, if not rated, are of
                     comparable quality as determined by the Adviser. See
                     "General Investment Policies."
 
                           The Portfolio may invest in variable and floating
                     rate obligations, may purchase securities on a
                     "when-issued" basis, and reserves the right to engage in
                     transactions involving standby commitments. The Portfolio
                     will not invest more than 10% of its net assets in
                     securities which are considered illiquid.
 
                           For a description of the Portfolio's permitted
                     investments and ratings, see the "Description of Permitted
                     Investments and Risk Factors" and the Statement of
                     Additional Information.
RISK FACTORS
          ______________________________________________________________________
CALIFORNIA RISK FACTORS
                     THE PORTFOLIO'S CONCENTRATION IN INVESTMENTS IN MUNICIPAL
                     SECURITIES OF A SINGLE STATE INVOLVES GREATER RISKS THAN
                     MONEY MARKET FUNDS THAT ARE DIVERSIFIED ACROSS ISSUERS
                     LOCATED IN A NUMBER OF STATES. These risks result primarily
                     from (1) amendments to the California
 
                                                                               5
<PAGE>
                     Constitution and other statutes that limit the taxing and
                     spending authority of California government entities, and
                     (2) a variety of California laws and regulations that may
                     affect, directly or indirectly, the issuer of California
                     municipal securities.
 
                           There could be economic, business, or political
                     developments which might affect all Municipal Securities of
                     a similar type. To the extent that a significant portion of
                     the Portfolio's assets are invested in Municipal Securities
                     payable from revenues on similar projects, the Portfolio
                     will be subject to the risks presented by such projects to
                     a greater extent than it would be if the Portfolio's assets
                     were not so invested. Moreover, in seeking to attain its
                     investment objective, the Portfolio may invest all or any
                     part of its assets in Municipal Securities that are
                     industrial development bonds.
 
INVESTMENT
LIMITATIONS
        ________________________________________________________________________
 
                     The investment objective and investment limitations are
                     fundamental policies of the Portfolio. Fundamental policies
                     cannot be changed with respect to the Trust or the
                     Portfolio without the consent of the holders of a majority
                     of the Trust's or the Portfolio's outstanding shares. It is
                     a fundamental policy of the Portfolio to use its best
                     efforts to maintain a constant net asset value of $1.00 per
                     share.
 
                     THE PORTFOLIO MAY NOT:
 
                     1. Purchase securities of any issuer (except securities
                        issued or guaranteed by the United States Government,
                        its agencies or instrumentalities) if, as a result, more
                        than 5% of the total assets of the Portfolio (based on
                        current value at the time of investment) would be
                        invested in the securities of such issuer. This
                        restriction applies to 75% of the Portfolio's assets.
 
                     2. Purchase any securities which would cause more than 25%
                        of the total assets of the Portfolio, based on fair
                        market value at the time of such purchase, to be
                        invested in the securities of one or more issuers
                        conducting their principal business activities in the
                        same industry, provided that this limitation does not
                        apply to investments in obligations issued or guaranteed
                        by the United States Government or its agencies and
                        instrumentalities or to investments in tax-exempt
                        securities issued by governments or political
                        subdivisions of governments.
 
                     3. Borrow money except for temporary or emergency purposes
                        and then only in an amount not exceeding 10% of the
                        value of the total assets of the Portfolio. All
                        borrowings will be repaid before making additional
                        investments and any interest paid on such borrowings
                        will reduce the income of the Portfolio.
 
                     The foregoing percentage limitations will apply at the time
                     of the purchase of a security. Additional fundamental
                     investment limitations are set forth in the Statement of
                     Additional Information.
 
                                                                               6

          ______________________________________________________________________
 
                     SEI Fund Management (the "Manager" and the "Transfer
                     Agent") provides the Trust with overall management
                     services, regulatory reporting, all necessary office space,
                     equipment, personnel and facilities, and serves as
                     institutional transfer agent and dividend disbursing agent.
 
                           For these services, the Manager is entitled to a fee,
                     which is calculated daily and paid monthly, at an annual
                     rate of .23% of the average daily net assets of the
                     Portfolio. The Manager has voluntarily agreed to waive a
                     portion of its fees in order to limit the total operating
                     expenses of CNI Class shares of the Portfolio (as a
                     percentage of the Portfolio's average daily net assets
                     attributable to CNI Class shares) to not more than .78%, on
                     an annualized basis. The Manager reserves the right, in its
                     sole discretion, to terminate its voluntary fee waiver at
                     any time. For the fiscal year ended August 31, 1997, the
                     Portfolio paid management fees, after waivers, of .19% of
                     its average daily net assets.
THE ADVISER
         _______________________________________________________________________
 
                     Weiss, Peck & Greer, L.L.C., serves as the Portfolio's
                     investment adviser under an advisory agreement (the
                     "Advisory Agreement") with the Trust. Under the Advisory
                     Agreement, the Adviser invests the assets of the Portfolio,
                     and continuously reviews, supervises and administers the
                     investment program of the Portfolio. The Adviser is
                     independent of the Manager and discharges its
                     responsibilities subject to the supervision of, and
                     policies set by, the Trustees of the Trust.
 
                           The Adviser is a limited liability company founded as
                     a limited partnership in 1970, and engages in investment
                     management, venture capital management and management
                     buyouts. The Adviser has been active since its founding in
                     managing portfolios of tax exempt securities. As of
                     September 30, 1997, total assets under management were
                     approximately $14.6 billion. The principal business address
                     of the Adviser is One New York Plaza, New York, New York
                     10004.
 
                           Janet Fiorenza acts as portfolio manager for the
                     Portfolio. Ms. Fiorenza, a Principal of the Adviser, has
                     been associated with the Adviser's Tax Exempt Fixed Income
                     Group since 1988, and its predecessor since 1980.
 
                           For its services to the Portfolio, the Adviser is
                     entitled to a fee, which is calculated daily and paid
                     monthly, at an annual rate of .05% of the combined average
                     daily net assets of the money market portfolios of the
                     Trust advised by the Adviser up to $500 million, .04% of
                     such assets from $500 million to 1 billion, and .03% of
                     such assets in excess of $1 billion. Such fees are
                     allocated daily among these portfolios on the basis of
                     their relative net assets. For the fiscal year ended August
                     31, 1997, the Portfolio paid advisory fees, after waivers,
                     of .04% of its relative net assets.
 
                                                                               7

DISTRIBUTION AND
SHAREHOLDER
SERVICING
      __________________________________________________________________________
 
                     SEI Investments Distribution Co. (the "Distributor"), a
                     wholly owned subsidiary of SEI Investments Company ("SEI
                     Investments"), serves as the Portfolio's distributor
                     pursuant to a distribution agreement (the "Distribution
                     Agreement") with the Trust.
 
                           The Rule 12b-1 Plan applicable to CNI Class shares of
                     the Portfolio (the "CNI Class Plan") provides for payments
                     to the Distributor at an annual rate of .50% of the
                     Portfolio's average daily net assets attributable to CNI
                     Class shares. This payment is characterized as
                     "compensation," and is not directly tied to expenses
                     incurred by the Distributor; the payment the Distributor
                     receives during any year may therefore be higher or lower
                     than its actual expenses. This payment compensates the
                     Distributor for its services in connection with
                     distribution assistance, and some or all of it may be used
                     to pay financial institutions and intermediaries such as
                     banks, savings and loan associations, insurance companies,
                     and investment counselors, broker-dealers (including the
                     Distributor's affiliates and subsidiaries) for services or
                     reimbursement of expenses incurred in connection with
                     distribution assistance. If the Distributor's expenses are
                     less than its fees under the CNI Class Plan, the Trust will
                     still pay the full fee and the Distributor will realize a
                     profit, but the Trust will not be obligated to pay in
                     excess of the full fee, even if the Distributor's actual
                     expenses are higher.
 
                           The Portfolio has adopted a shareholder servicing
                     plan (the "CNI Class Service Plan") under which firms,
                     including the Distributor, that provide shareholder
                     services may receive compensation therefor. Under the CNI
                     Class Service Plan, the Distributor is entitled to receive
                     shareholder service fees at an annual rate of up to .25% of
                     average daily net assets in return for the Distributor's
                     (or its agent's) efforts in maintaining client accounts;
                     arranging for bank wires; responding to client inquiries
                     concerning services provided or investment; and assisting
                     clients in changing dividend options, account designations
                     and addresses. The Distributor may provide those services
                     itself or may enter into arrangements under which third
                     parties provide such services and are compensated by the
                     Distributor. In addition, the Portfolio has adopted
                     shareholder servicing plans for its Class A, Class B and
                     Class C shares that are similar to the plan described
                     above. The Distributor may retain as a profit any
                     difference between the fee it receives and the amount it
                     pays to third parties.
 
                           It is possible that an institution may offer
                     different classes of shares to its customers and provide
                     differing services to the classes of the Portfolio, and
                     thus receive different compensation with respect to
                     different classes. These financial institutions may also
                     charge separate fees to their customers.
 
                           The Trust may execute brokerage or other agency
                     transactions through the Distributor for which the
                     Distributor may receive compensation.
 
                                                                               8
<PAGE>
                           The Distributor may, from time to time and at its own
                     expense, provide promotional incentives, in the form of
                     cash or other compensation to certain financial
                     institutions whose representatives have sold or are
                     expected to sell significant amounts of the Portfolio's
                     shares.
 
PURCHASE AND
REDEMPTION OF SHARES
    ____________________________________________________________________________
 
                     Financial institutions may acquire shares of the Portfolio
                     for their own account, or as a record owner on behalf of
                     fiduciary, agency or custody accounts, by placing orders
                     with the Transfer Agent (or its authorized agent).
                     Institutions that use certain SEI proprietary systems may
                     place orders electronically through those systems.
                     Financial institutions that purchase shares for the
                     accounts of their customers may impose separate charges on
                     these customers for account services. Financial
                     institutions may impose an earlier cut-off time for receipt
                     of purchase orders directed through them to allow for
                     processing and transmittal of these orders to the Transfer
                     Agent for effectiveness on the same day.
 
                           Shares of the Portfolio may be purchased or redeemed
                     on days on which the New York Stock Exchange is open for
                     business ("Business Days"). However, money market fund
                     shares cannot be purchased by Federal Reserve wire on
                     federal holidays restricting wire transfers. Shareholders
                     who desire to purchase shares for cash must place their
                     orders with the Transfer Agent (or its authorized agent)
                     prior to the calculation of net asset value on any Business
                     Day for the order to be accepted on that Business Day. Cash
                     investments must be transmitted or delivered in federal
                     funds to the wire agent by the close of business on the
                     same day the order is placed for the Portfolio. The Trust
                     reserves the right to reject a purchase order when the
                     Distributor determines that it is not in the best interest
                     of the Trust or shareholders to accept such purchase order.
 
                           The Trust will send shareholders a statement of
                     shares owned after each transaction. The purchase price of
                     shares is the net asset value next determined after a
                     purchase order is received and accepted by the Trust. The
                     purchase price of shares of the Portfolio is expected to
                     remain constant at $1.00. The net asset value per share of
                     the Portfolio is determined by dividing the total value of
                     its investments and other assets, less any liabilities, by
                     the total number of outstanding shares of the Portfolio.
                     The Portfolio's investments will be valued by the amortized
                     cost method described in the Statement of Additional
                     Information. Net asset value per share is determined on
                     each Business Day as of 2:00 p.m., Eastern time.
 
                           Shareholders who desire to redeem shares of the
                     Portfolio must place their redemption orders with the
                     Transfer Agent (or its authorized agent) prior to the
                     determination of net asset value and in accordance with the
                     procedures described below for the order to be accepted on
                     that Business Day. Otherwise, redemption orders will be
                     effective on the next Business Day. Payment for redemption
                     orders from the Portfolio
 
                                                                               9
<PAGE>
                     received before the calculation of net asset value will be
                     made the same day by transfer of federal funds. The
                     redemption price is the net asset value per share of the
                     Portfolio next determined after receipt by the Transfer
                     Agent (or its authorized agent) of an effective redemption
                     order.
 
                           Purchase and redemption orders may be placed by
                     telephone. Neither the Trust nor its transfer agent will be
                     responsible for any loss, liability, cost or expense for
                     acting upon wire instructions or upon telephone
                     instructions that it reasonably believes to be genuine. The
                     Trust and its transfer agent will each employ reasonable
                     procedures to confirm that instructions communicated by
                     telephone are genuine, including requiring a form of
                     personal identification prior to acting upon instructions
                     received by telephone and recording telephone instructions.
 
                           If market conditions are extraordinarily active, or
                     other extraordinary circumstances exist, shareholders may
                     experience difficulties placing redemption orders by
                     telephone, and may wish to consider placing orders by other
                     means.
PERFORMANCE
          ______________________________________________________________________
 
                     From time to time the Portfolio advertises its "current
                     yield," "tax equivalent yield" and "effective yield." These
                     figures are based on historical earnings and are not
                     intended to indicate future performance. The "current
                     yield" of the Portfolio refers to the income generated by
                     an investment over a seven-day period which is then
                     "annualized." That is, the amount of income generated by
                     the investment during the 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" (also
                     called "effective compound yield") is calculated similarly
                     but, when annualized, the income earned by an investment is
                     assumed to be reinvested. The "effective yield" will be
                     slightly higher than the "current yield" because of the
                     compounding effect of this assumed reinvestment. The "tax
                     equivalent yield" is calculated by determining the rate of
                     return that would have been achieved on a fully taxable
                     investment to produce the after-tax equivalent of the
                     Portfolio's yield, assuming certain tax brackets for a
                     shareholder.
 
                           The Portfolio may periodically compare its
                     performance to that of: (i) other mutual funds tracked by
                     mutual fund rating services (such as Lipper Analytical),
                     financial and business publications and periodicals; (ii)
                     broad groups of comparable mutual funds; (iii) unmanaged
                     indices which may assume investment of dividends but
                     generally do not reflect deductions for administrative and
                     management costs; or (iv) other investment alternatives.
 
                           The performance of Class A shares of the Portfolio
                     will normally be higher than that of Class B, Class C or
                     CNI Class shares because of the additional distribution
                     and/or administrative services expenses charged to Class B,
                     Class C and CNI Class shares.
 
                                                                              10

TAXES
  ______________________________________________________________________________
 
                     The following summary of federal and state income tax
                     consequences is based on current tax laws and regulations,
                     which may be changed by legislative, judicial or
                     administrative action. No attempt has been made to present
                     a detailed explanation of the federal, state or local
                     income tax treatment of the Portfolio or its shareholders.
                     Accordingly, shareholders are urged to consult their tax
                     advisers regarding specific questions as to federal, state
                     and local income taxes. Additional information concerning
                     taxes is set forth in the Statement of Additional
                     Information.
TAX STATUS OF THE
PORTFOLIO
                     The Portfolio is treated as a separate entity for federal
                     income tax purposes and is not combined with the Trust's
                     other portfolios. The Portfolio intends to continue to
                     qualify for the special tax treatment afforded regulated
                     investment companies under Subchapter M of the Internal
                     Revenue Code of 1986, as amended (the "Code"), so as to be
                     relieved of federal income tax on net investment company
                     taxable income and net capital gain (the excess of net
                     long-term capital gain over net short-term capital loss)
                     distributed to shareholders.
TAX STATUS OF
DISTRIBUTIONS
                     The Portfolio intends to distribute substantially all of
                     its net investment income (including net short-term capital
                     gain) to shareholders. If, at the close of each quarter of
                     its taxable year, at least 50% of the value of the
                     Portfolio's total assets consists of obligations the
                     interest on which is excludable from gross income, the
                     Portfolio may pay "exempt-interest dividends" to its
                     shareholders. Exempt-interest dividends are excludable from
                     a shareholder's gross income for federal income tax
                     purposes, but may have certain collateral federal tax
                     consequences including alternative minimum tax
                     consequences. In addition, the receipt of exempt-interest
                     dividends may cause persons receiving Social Security or
                     Railroad Retirement benefits to be taxable on a portion of
                     such benefits. See the Statement of Additional Information.
 
                           Any dividends paid out of income realized by the
                     Portfolio on taxable securities will be taxable to
                     shareholders as ordinary income (whether received in cash
                     or in additional shares) to the extent of the Portfolio's
                     earnings and profits and will not qualify for the
                     dividends-received deduction for corporate shareholders.
                     Distributions to shareholders of net capital gains of the
                     Portfolio also will not qualify for the dividends received
                     deduction and will be taxable to shareholders as long-term
                     capital gain, whether received in cash or additional
                     shares, and regardless of how long a shareholder has held
                     the shares.
 
                           Dividends declared by the Portfolio in October,
                     November or December of any year and payable to
                     shareholders of record on a date in any such month will be
                     deemed to have been paid by the Portfolio and received by
                     the shareholders on December 31 of that year if paid by the
                     Portfolio at any time during the following January. The
                     Portfolio intends to make sufficient distributions prior to
                     the end of each calendar year to avoid liability for
                     federal excise tax applicable to regulated investment
                     companies.
 
                                                                              11

                           Interest on indebtedness incurred or continued by a
                     shareholder in order to purchase or carry shares of the
                     Portfolio is not deductible for federal income tax purposes
                     to the extent that it relates to exempt-interest dividends
                     distributed to the shareholders during the taxable year.
                     Furthermore, the Portfolio may not be an appropriate
                     investment for persons (including corporations and other
                     business entities) who are "substantial users" (or persons
                     related to "substantial users") of facilities financed by
                     industrial development bonds or private activity bonds.
                     Such persons should consult their tax advisers before
                     purchasing shares. The Portfolio will report annually to
                     its shareholders the portion of dividends that is taxable
                     and the portion that is tax-exempt based on income received
                     by the Portfolio during the year to which the dividends
                     relate.
 
                           Each sale, exchange or redemption of the Portfolio's
                     shares is a taxable transaction to the shareholder.
CALIFORNIA TAXES
                     The following is a general, abbreviated summary of certain
                     of the provisions of the California Revenue and Taxation
                     Code presently in effect as they directly govern the
                     taxation of shareholders subject to California personal
                     income tax. These provisions are subject to change by
                     legislative or administrative action, and any such change
                     may be retroactive.
 
                           The Portfolio intends to qualify to pay dividends to
                     shareholders that are exempt from California personal
                     income tax ("California exempt-interest dividends"). The
                     Portfolio will qualify to pay California exempt-interest
                     dividends if (1) at the close of each quarter of the
                     Portfolio's taxable year, at least 50 percent of the value
                     of the Portfolio's total assets consists of obligations the
                     interest on which would be exempt from California personal
                     income tax if the obligations were held by an individual
                     ("California Tax Exempt Obligations") and (2) the Portfolio
                     continues to qualify as a regulated investment company. The
                     Portfolio will notify its shareholders of the amount of
                     exempt-interest dividends each year.
 
                           If the Portfolio qualifies to pay California
                     exempt-interest dividends, dividends distributed to
                     shareholders will be considered California exempt-interest
                     dividends if they meet certain requirements. See the
                     Statement of Additional Information.
 
                           Corporations subject to California franchise tax that
                     invest in the Portfolio may not be entitled to exclude
                     California exempt-interest dividends from income.
 
                           Distributions that do not qualify for treatment as
                     California exempt-interest dividends (including those
                     distributions to shareholders taxable as long-term capital
                     gains for federal income tax purposes) will be taxable to
                     shareholders at ordinary income tax rates for California
                     personal income tax purposes to the extent of the
                     Portfolio's earnings and profits.
 
                           Interest on indebtedness incurred or continued by a
                     shareholder in connection with the purchase of shares of
                     the Portfolio will not be deductible for California
                     personal income tax purposes if the Portfolio distributes
                     California exempt-interest dividends.
 
                                                                              12

GENERAL INFORMATION
         _______________________________________________________________________
THE TRUST
                     The Trust was organized as a Massachusetts business trust
                     under a Declaration of Trust dated March 15, 1982. The
                     Declaration of Trust permits the Trust to offer separate
                     portfolios of shares and different classes of each
                     portfolio. In addition to the Portfolio, the Trust consists
                     of the following portfolios: Tax Free Portfolio,
                     Institutional Tax Free Portfolio, Intermediate-Term
                     Municipal Portfolio, Pennsylvania Municipal Portfolio, New
                     York Intermediate-Term Municipal Portfolio, and
                     Pennsylvania Tax Free Portfolio. All consideration received
                     by the Trust for shares of any portfolio and all assets of
                     such portfolio belong to that portfolio and would be
                     subject to liabilities related thereto.
 
                           The Trust pays its expenses, including fees of its
                     service providers, audit and legal expenses, expenses of
                     preparing prospectuses, proxy solicitation materials and
                     reports to shareholders, costs of custodial services and
                     registering the shares under federal and state securities
                     laws, pricing, insurance expenses, litigation and other
                     extraordinary expenses, brokerage costs, interest charges,
                     taxes and organization expenses.
TRUSTEES OF THE TRUST
                     The management and affairs of the Trust are supervised by
                     the Trustees under the laws of the Commonwealth of
                     Massachusetts. The Trustees have approved contracts under
                     which, as described above, certain companies provide
                     essential services to the Trust.
VOTING RIGHTS
                     Each share held entitles the shareholder of record to one
                     vote. The shareholders of each portfolio or class will vote
                     separately on matters relating solely to that portfolio or
                     class, such as any distribution plan. As a Massachusetts
                     business trust, the Trust is not required to hold annual
                     meetings of shareholders, but approval will be sought for
                     certain changes in the operation of the Trust and for the
                     election of Trustees under certain circumstances. In
                     addition, a Trustee may be removed by the remaining
                     Trustees or by shareholders at a special meeting called
                     upon written request of shareholders owning at least 10% of
                     the outstanding shares of the Trust. In the event that such
                     a meeting is requested the Trust will provide appropriate
                     assistance and information to the shareholders requesting
                     the meeting.
REPORTING
                     The Trust issues unaudited financial statements
                     semi-annually and audited financial statements annually.
                     The Trust furnishes proxy statements and other reports to
                     shareholders of record.
SHAREHOLDER INQUIRIES
                     Shareholder inquiries should be directed to the Manager,
                     SEI Fund Management, Oaks, Pennsylvania, 19456.
DIVIDENDS
                     The net investment income (exclusive of capital gains) of
                     the Portfolio is determined and declared on each Business
                     Day as a dividend for shareholders of record as of the
                     close of business on that day. Dividends are paid by the
                     Portfolio in federal funds or in additional shares at the
                     discretion of the shareholder on the first Business Day of
                     each month. Dividends will be paid on the next Business Day
                     to shareholders who redeem all of their
 
                                                                              13
<PAGE>
                     shares of the Portfolio at any time during the month.
                     Currently, capital gains, if any, are distributed at the
                     end of the calendar year.
 
                           Shareholders automatically receive all income
                     dividends and capital gain distributions in additional
                     shares, unless the shareholder has elected to take such
                     payment in cash. Shareholders may change their election by
                     providing written notice to the Manager at least 15 days
                     prior to the distribution.
 
                           The dividends on Class A shares of the Portfolio are
                     normally higher than those on Class B, Class C or CNI Class
                     shares because of the additional distribution and/or
                     administrative services expenses charged to Class B, Class
                     C and CNI Class shares.

DESCRIPTION OF
PERMITTED
INVESTMENTS AND RISK
FACTORS   ______________________________________________________________________
 
                     The following is a description of certain of the permitted
                     investments for the Portfolios, and the associated risk
                     factors:
MONEY MARKET SECURITIES
                     Money market securities are high-quality,
                     dollar-denominated, short-term debt instruments. They
                     consist of: (i) bankers' acceptances, certificates of
                     deposits, notes and time deposits of highly-rated U.S.
                     banks; (ii) U.S. Treasury obligations and obligations
                     issued by the agencies and instrumentalities of the U.S.
                     Government; and (iii) repurchase agreements involving any
                     of the foregoing obligations entered into with highly-rated
                     banks and broker-dealers.
MUNICIPAL SECURITIES
                     Municipal Securities consist of (i) debt obligations issued
                     by or on behalf of public authorities to obtain funds to be
                     used for various public facilities, for refunding
                     outstanding obligations, for general operating expenses and
                     for lending such funds to other public institutions and
                     facilities, and (ii) certain private activity and
                     industrial development bonds issued by or on behalf of
                     public authorities to obtain funds to provide for the
                     construction, equipment, repair or improvement of privately
                     operated facilities.
 
                           General obligation bonds are backed by the taxing
                     power of the issuing municipality. Revenue bonds are backed
                     by the revenues of a project or facility, tolls from a toll
                     bridge, for example. Certificates of participation
                     represent an interest in an underlying obligation or
                     commitment such as an obligation issued in connection with
                     a leasing arrangement. The payment of principal and
                     interest on private activity and industrial
 
                                                                              14
<PAGE>
                     development bonds generally is dependent solely on the
                     ability of the facility's user to meet its financial
                     obligations and the pledge, if any, of real and personal
                     property so financed as security for such payment.
 
                           Municipal notes include general obligation notes, tax
                     anticipation notes, revenue anticipation notes, bond
                     anticipation notes, certificates of indebtedness, demand
                     notes and construction loan notes and participation
                     interests in municipal notes. Municipal bonds include
                     general obligation bonds, revenue or special obligation
                     bonds, private activity and industrial development bonds
                     and participation interests in municipal bonds.
REPURCHASE AGREEMENTS
                     Repurchase agreements are arrangements by which a Portfolio
                     obtains a security and simultaneously commits to return the
                     security to the seller at an agreed upon price (including
                     principal and interest) on an agreed upon date within a
                     number of days from the date of purchase. Repurchase
                     agreements are considered loans under the 1940 Act.
STANDBY COMMITMENTS AND
PUTS
                     Securities subject to standby commitments or puts permit
                     the holder thereof to sell the securities at a fixed price
                     prior to maturity. Securities subject to a standby
                     commitment or put may be sold at any time at the current
                     market price. However, unless the standby commitment or put
                     was an integral part of the security as originally issued,
                     it may not be marketable or assignable; therefore, the
                     standby commitment or put would only have value to the
                     Portfolio owning the security to which it relates. In
                     certain cases, a premium may be paid for a standby
                     commitment or put, which premium will have the effect of
                     reducing the yield otherwise payable on the underlying
                     security. The Portfolio will limit standby commitment or
                     put transactions to institutions believed to present
                     minimal credit risks.
U.S. GOVERNMENT
OBLIGATIONS
                     Obligations issued by the U.S. Treasury or issued or
                     guaranteed by agencies of the U.S. Government and
                     obligations issued or guaranteed by instrumentalities of
                     the U.S. Government. Some of these securities are supported
                     by the full faith and credit of the U.S. Treasury (E.G.,
                     Government National Mortgage Association securities),
                     others are supported by the right of the issuer to borrow
                     from the Treasury (E.G., Federal Farm Credit Bank
                     securities), while still others are supported only by the
                     credit of the instrumentality (E.G., Fannie Mae
                     securities).
VARIABLE AND FLOATING
RATE INSTRUMENTS
                     Certain of the obligations purchased by the Portfolio may
                     carry variable or floating rates of interest and may
                     involve a conditional or unconditional demand feature. Such
                     obligations may include variable amount master demand
                     notes. Such instruments bear interest at rates which are
                     not fixed, but which vary with changes in specified market
                     rates or indices. The interest rates on these securities
                     may be reset daily, weekly, quarterly or at some other
                     interval, and may have a floor or ceiling on interest rate
                     changes. There is a risk that the current interest rate on
                     such obligations may not accurately reflect existing market
                     interest rates. A demand instrument with a demand notice
                     period exceeding seven days may be considered illiquid if
                     there is no secondary market for such security.
 
                                                                              15

WHEN-ISSUED AND DELAYED
DELIVERY SECURITIES
                     When-issued or delayed delivery transactions involve the
                     purchase of an instrument with payment and delivery taking
                     place in the future. Delivery of and payment for these
                     securities may occur a month or more after the date of the
                     purchase commitment. The Portfolio will maintain with the
                     custodian a separate account with liquid securities or cash
                     in an amount at least equal to these commitments. The
                     interest rate realized on these securities is fixed as of
                     the purchase date, and no interest accrues to the Portfolio
                     before settlement.
 
                                                                              16

certain classes of which offer shareholders a convenient means of investing
their funds in one or more professionally managed diversified and non-

Class D shares are available through SEI Investments Distribution Co. (the
Trust's distributor), and through participating broker-dealers, financial
institutions and other organizations. This Prospectus offers Class D shares of
the Trust's Tax Free Portfolio (the "Portfolio"), a money market portfolio.

GOVERNMENT, AND THERE CAN BE NO ASSURANCE THAT THE PORTFOLIO WILL BE ABLE TO
MAINTAIN A STABLE NET ASSET VALUE OF $1.00 PER SHARE.

 EXCHANGE COMMISSION, NOR HAS THE SECURITIES AND EXCHANGE COMMISSION PASSED

 CONTRARY IS A CRIMINAL OFFENSE.
 
 THE TRUST'S SHARES ARE NOT DEPOSITS OR OBLIGATIONS OF, OR GUARANTEED OR
 ENDORSED BY, ANY BANK. THE SHARES ARE NOT FEDERALLY INSURED BY THE FEDERAL
 DEPOSIT INSURANCE CORPORATION, THE FEDERAL RESERVE BOARD OR ANY OTHER

                     which is exempt from federal
                     income taxes. The investment
                     policies of the Portfolio entail

- --------------------------------------------------------------------------------
 
Class D shares of the Portfolio are sold on a continuous basis and may be
purchased directly from the Trust's Transfer Agent, DST Systems, Inc. Shares may
also be purchased through financial institutions, broker-dealers, or other
organizations which have established a dealer agreement or other arrangement
with SEI Investments Distribution Co. ("Intermediaries"). For more information
about the following topics, see "Additional Information About Doing Business
with Us."
- --------------------------------------------------------------------------------
HOW TO BUY, SELL AND
EXCHANGE SHARES
THROUGH
INTERMEDIARIES
                     Class D shares of the Portfolio may be purchased through
                     Intermediaries. Contact your Intermediary for information
                     on how to buy, sell and exchange shares. To allow for
                     processing and transmittal of orders to the Transfer Agent
                     (or its authorized agent) on the
                     same day, Intermediaries may
                     impose earlier cut-off times for
                     receipt of purchase orders.
                     Certain Intermediaries may
                     charge customer account fees.
                     Information concerning any
                     charges will be provided to the
                     customer by the Intermediary.
 
                           The shares you purchase
                     through an Intermediary may be
                     held "of record" by that
                     Intermediary. If you want to
                     transfer the registration of
                     shares beneficially owned by
                     you, but held "of record" by an Intermediary, you should
                     call the Intermediary to request this change.
 ...........................................................................
[>] WHAT IS AN INTERMEDIARY?
ANY ENTITY, SUCH AS A BANK, BROKER-DEALER, OTHER FINANCIAL INSTITUTION,
ASSOCIATION OR ORGANIZATION WHICH HAS ENTERED INTO AN ARRANGEMENT WITH THE
DISTRIBUTOR TO SELL CLASS D SHARES TO ITS CUSTOMERS.
 ...........................................................................
 
HOW TO BUY SHARES
FROM THE TRANSFER
AGENT
                     Account application forms may be obtained by calling
                     1-800-437-6016.
OPENING AN ACCOUNT BY
CHECK
                     You may buy Class D shares by mailing a completed
                     application and a check (or other negotiable bank
                     instrument or money order) to the Transfer Agent (or its
                     authorized agent). All purchases made by check should be in
                     U.S. dollars and made payable to "Class D Shares (Tax Free
                     Portfolio)." If you send a check that does not clear, the
                     purchase will be canceled and you could be liable for any
                     losses or fees incurred. Third-party checks, credit cards,
                     credit card checks and cash will not be accepted. When
                     purchases are made by check (including certified or
                     cashier's checks), redemption proceeds will not be
                     forwarded until the check providing for the investment
                     being redeemed has cleared (which may take up to 15 days).
BY FED WIRE
                     You may buy shares by Fed Wire by calling 1-800-437-6016.
AUTOMATIC INVESTMENT
PLAN ("AIP")
                     You may systematically buy Class D shares through
                     deductions from your checking or savings accounts, provided
                     these accounts are maintained through banks which are part
                     of the Automated Clearing House ("ACH") system. You may
                     purchase shares on a fixed schedule (semi-monthly or
                     monthly) with amounts as low as $25, or as high as
                     $100,000. Upon notice, the amount you commit to the AIP may
                     be changed or canceled at any time. The AIP is subject to
                     account minimum initial purchase amounts and minimum
                     balance maintenance requirements.
 
                                                                               6

EXCHANGING SHARES
WHEN CAN YOU
EXCHANGE SHARES?
                     Once good payment for your shares has been received and
                     accepted (I.E., an account has been established), you may
                     exchange some or all of your shares for Class D shares of
                     the Trust or of SEI Liquid Asset Trust, SEI Daily Income
                     Trust, SEI International Trust and SEI Institutional
                     Managed Trust ("SEI Funds"). Exchanges are made at net
                     asset value plus any applicable sales charge.
WHEN DO SALES CHARGES
APPLY TO AN EXCHANGE?
                     SEI Funds' portfolios that are
                     not money market portfolios
                     currently impose a sales charge
                     on Class D shares. If you
                     exchange into one of these "non-
                     money market" portfolios, you
                     will have to pay a sales charge
                     on any portion of your exchanged
                     Class D shares for which you
                     have not previously paid a sales
                     charge.
 
                           If you previously paid a
                     sales charge on your Class D
                     shares, no additional sales
                     charge will be assessed when you
                     exchange those Class D shares
                     for other Class D shares.
 
                           If you buy Class D shares
                     of a "non-money market" fund and
                     you receive a sales charge
                     waiver, you will be deemed to have paid the sales charge
                     for purposes of this exchange privilege. In calculating any
                     sales charge payable on your exchange, the Trust will
                     assume that the first shares you exchange are those on
                     which you have already paid a sales charge. Sales charge
                     waivers may also be available under certain circumstances
                     described in the SEI Funds' prospectuses.
 ...........................................................................
[>] HOW DOES AN EXCHANGE TAKE PLACE?
WHEN MAKING AN EXCHANGE, YOU AUTHORIZE THE SALE OF YOUR SHARES OF ONE OR MORE
PORTFOLIOS IN ORDER TO PURCHASE THE SHARES OF ANOTHER PORTFOLIO. IN OTHER WORDS,
YOU ARE EXECUTING A SELL ORDER AND THEN A BUY ORDER. THIS SALE OF YOUR SHARES IS
A TAXABLE EVENT WHICH COULD RESULT IN A TAXABLE GAIN OR LOSS.
 ...........................................................................
 
                           The Trust reserves the right to change the terms and
                     conditions of the exchange privilege discussed herein, or
                     to terminate the exchange privilege, upon 60 days' notice.
                     The Trust also reserves the right to deny an exchange
                     request made within 60 days of the purchase of a "non-money
                     market" portfolio.
REQUESTING AN EXCHANGE
OF SHARES
                     To request an exchange, you must provide proper
                     instructions in writing to the Transfer Agent (or its
                     authorized agent). Telephone exchanges will also be
                     accepted if you previously elected this option on your
                     account application.
 
                           In the case of shares held "of record" by an
                     Intermediary but beneficially owned by you, you should
                     contact the Intermediary who will contact the Transfer
                     Agent and effect the exchange on your behalf.
 
HOW TO SELL SHARES
THROUGH THE
TRANSFER AGENT
                     To sell your shares, a written request for redemption in
                     good order must be received by the Transfer Agent (or its
                     authorized agent). Valid written redemption requests will
                     be effective on receipt. All shareholders of record must
                     sign the redemption request. The Transfer Agent may require
                     that the signatures on written requests be guaranteed.
 
                                                                               7

BY MAIL
                     For information about the proper form of redemption
                     requests, call 1-800-437-6016. You may also have the
                     proceeds mailed to an address of record or mailed (or sent
                     by ACH) to a commercial bank account previously designated
                     on the Account Application or specified by written
                     instruction to the Transfer Agent. There is no charge for
                     having redemption requests mailed to a designated bank
                     account.
BY TELEPHONE
                     You may sell your shares by telephone if you previously
                     elected that option on the Account Application. You may
                     have the proceeds mailed to the address of record, wired or
                     sent by ACH to a commercial bank account previously
                     designated on the Account Application.
                     Under most circumstances,
                     payments will be transmitted on
                     the next Business Day following
                     receipt of a valid telephone
                     request for redemption. Wire
                     redemption requests may be made
                     by calling 1-800-437-6016, who
                     will subtract a wire redemption
                     charge (presently $10.00) from
                     the amount of the redemption.
SYSTEMATIC WITHDRAWAL
PLAN ("SWP")
                     You may establish a systematic
                     withdrawal plan for an account
                     with a $10,000 minimum balance.
                     Under the plan, redemptions can
                     be automatically processed from
                     accounts (monthly, quarterly,
                     semi-annually or annually) by
                     check or by ACH with a minimum
                     redemption amount of $50.
 ...........................................................................
[>] WHAT IS A SIGNATURE GUARANTEE?
A SIGNATURE GUARANTEE VERIFIES THE AUTHENTICITY OF YOUR SIGNATURE AND MAY BE
OBTAINED FROM ANY OF THE FOLLOWING: BANKS, BROKERS, DEALERS, CERTAIN CREDIT
UNIONS, SECURITIES EXCHANGE OR ASSOCIATION, CLEARING AGENCY OR SAVINGS
ASSOCIATION. A NOTARY PUBLIC CANNOT PROVIDE A SIGNATURE GUARANTEE.
 ...........................................................................
CHECK-WRITING
                     Check-Writing Service is offered free of charge to Class D
                     shareholders in the Portfolio. You may redeem shares by
                     writing checks on your account for $500 or more. Once you
                     have signed and returned a signature card, you will receive
                     a supply of checks. A check may be made payable to any
                     person, and your account will continue to earn dividends
                     until the check clears.
 
                           Because of the difficulty of determining in advance
                     the exact value of your account, you may not use a check to
                     close your account. The checks are free, but your account
                     will be charged a fee for stopping payment of a check upon
                     your request or if the check cannot be honored because of
                     insufficient funds or other valid reasons.
 
                                                                               8

INVESTMENT OBJECTIVE
AND POLICIES
     ___________________________________________________________________________
 
                     The Portfolio's investment objective is to preserve
                     principal value and maintain a high degree of liquidity
                     while providing current income exempt from federal income
                     taxes. There can be no assurance that the Portfolio will
                     meet its investment objective.
 
                           The Portfolio invests in U.S. dollar denominated
                     municipal securities of issuers located in all fifty
                     states, the District of Columbia, Puerto Rico and other
                     U.S. territories and possessions
                     (collectively, "Municipal
                     Securities"). At least 80% of
                     the Portfolio's net assets will
                     be invested in securities the
                     interest on which is exempt from
                     federal income taxes, based on
                     opinions from bond counsel for
                     the issuers. This investment
                     policy is a fundamental policy
                     of the Portfolio. Under normal
                     conditions, the Portfolio will
                     invest at least 80% of its net
                     assets in securities the
                     interest on which is not a
                     preference item for purposes of
                     the federal alternative minimum
                     tax.
 
                           The Portfolio may purchase
                     municipal bonds, municipal notes
                     and tax-exempt commercial paper,
                     but only if such securities, at
                     the time of purchase, meet the quality, maturity and
                     diversification requirements imposed by Rule 2a-7. See
                     "General Investment Policies."

                           The Adviser will not invest more than 25% of
                     Portfolio assets in Municipal Securities (a) whose issuers
                     are located in the same state or (b) the interest on which
                     is derived from revenues of similar type projects. This
                     restriction does not apply to Municipal Securities in any
                     of the following categories; public housing authorities;
                     general obligations of states and localities; state and
                     local housing finance authorities or municipal utilities
                     systems.
 
                           There could be economic, business, or political
                     developments which might affect all Municipal Securities of
                     a similar type. To the extent that a significant portion of
                     the Portfolio's assets are invested in Municipal Securities
                     payable from revenues on similar projects, the Portfolio
                     will be subject to the peculiar risks presented by such
                     projects to a greater extent than it would be if the
                     Portfolio's assets were not so invested. Moreover, in
                     seeking to attain its investment objective, the Portfolio
                     may invest all or any part of its assets in Municipal
                     Securities that are industrial development bonds.
 
                                                                               9

GENERAL INVESTMENT
POLICIES
     ___________________________________________________________________________
 
                     In purchasing obligations, the Portfolio complies with the
                     requirements of Rule 2a-7 under the Investment Company Act
                     of 1940 (the "1940 Act"), as that Rule may be amended from
                     time to time. These requirements currently provide that the
                     Portfolio must limit its investments to securities with
                     remaining maturities of 397 days or less, and must maintain
                     a dollar-weighted average maturity of 90 days or less. In
                     addition, the Portfolio may only invest in eligible
                     securities. In general, this means securities rated in one
                     of the two highest categories for short-term securities by
                     at least two nationally recognized statistical rating
                     organizations ("NRSROs") (or by one NRSRO if only one NRSRO
                     has rated the security), or, if unrated, determined by
                     Weiss, Peck & Greer, L.L.C. (the "Adviser") to be of
                     equivalent quality. Since the Portfolio often purchases
                     securities supported by credit enhancements from banks and
                     other financial institutions, changes in the credit quality
                     of these institutions could cause losses to the Portfolio
                     and affect its share price.
 
                           Securities rated in the highest rating category
                     (E.G., A-1 by Standard & Poor's Corporation ("S&P")) by at
                     least two NRSROs (or, if unrated, determined by the Adviser
                     to be of comparable quality) are "first tier" securities.
                     Non-first tier securities rated in the second highest
                     rating category (E.G., A-2 by S&P) by at least one NRSRO
                     (or, if unrated, determined by the Adviser to be of
                     comparable quality) are considered to be "second tier"
                     securities. The Portfolio's investments in non-first tier
                     conduit securities will be limited to 5% of the Portfolio's
                     assets. Conduit securities are securities issued to finance
                     non-governmental private projects, such as housing
                     developments and retirement homes, and for which the
                     ultimate obligor is not a governmental issuer.
 
                           The Portfolio may invest in variable and floating
                     rate obligations, may purchase securities on a
                     "when-issued" basis, and reserves the right to engage in
                     transactions involving standby commitments. The Portfolio
                     will not invest more than 10% of its net assets in illiquid
                     securities.
 
                           The Adviser has discretion to invest up to 20% of the
                     Portfolio's assets in taxable money market instruments
                     (including repurchase agreements) and securities the
                     interest on which is a preference item for purposes of the
                     federal alternative minimum tax. However, the Portfolio
                     generally intends to be fully invested in federally
                     tax-exempt securities.

                     Investments and Risk Factors" and the Statement of

LIMITATIONS
        ________________________________________________________________________
 
                     The investment objective and investment limitations are
                     fundamental policies of the Portfolio. Fundamental policies
                     cannot be changed with respect to the Trust or the
                     Portfolio without the consent of the holders of a majority
                     of the Trust's or the Portfolio's outstanding shares. It is
                     a fundamental policy of the Portfolio to use its best
                     efforts to maintain a constant net asset value of $1.00 per
                     share.
 
                     THE PORTFOLIO MAY NOT:
 
                     1. Purchase securities of any issuer (except securities
                        issued or guaranteed by the United States Government,
                        its agencies or instrumentalities) if, as a result, more
                        than 5% of the total assets of the Portfolio (based on
                        current value at the time of investment) would be
                        invested in the securities of such issuer, provided,
                        however, that the Portfolio may invest up to 25% of its
                        total assets without regard to this restriction of, and
                        as permitted by, Rule 2a-7.
 
                     2. Purchase any securities which would cause more than 25%
                        of the total assets of the Portfolio, based on current
                        value at the time of such purchase, to be invested in
                        the securities of one or more issuers conducting their
                        principal business activities in the same industry,
                        provided that this limitation does not apply to
                        investments in obligations issued or guaranteed by the
                        U.S. Government or its agencies and instrumentalities.
 
                     3. Borrow money except for temporary or emergency purposes,
                        and then only in an amount not exceeding 10% of the
                        value of the total assets of the Portfolio. All
                        borrowings will be repaid before making additional
                        investments and any interest paid on such borrowings
                        will reduce the income of the Portfolio.
 
                           The foregoing percentage limitations will apply at
                     the time of the purchase of a security. Additional
                     fundamental investment limitations are set forth in the
                     Statement of Additional Information.

  ______________________________________________________________________________
 
                     SEI Fund Management (the "Manager") provides the Trust with
                     overall management services, regulatory reporting, all
                     necessary office space, equipment, personnel and
                     facilities, and serves as the Trust's institutional
                     transfer agent, dividend disbursing agent, and shareholder
                     servicing agent.
 
                           For these services, the Manager is entitled to a fee,
                     which is calculated daily and paid monthly, at an annual
                     rate of .36% of the average daily net assets of the
                     Portfolio. The Manager has voluntarily waived a portion of
                     its fees in order to limit the total
 
                                                                              11

                     operating expenses of the Class D shares of the Portfolio
                     to not more than .80% of the Portfolio's average daily net
                     assets attributable to Class D shares, on an annualized
                     basis. The Manager reserves the right, in its sole
                     discretion, to terminate this voluntary fee waiver at any
                     time.
 
                           For the fiscal year ended August 31, 1997, the
                     Portfolio paid management fees, after waivers, of .36% of
                     its average daily net assets.
 
                           The Trust and DST Systems, Inc., 1004 Baltimore
                     Avenue, Kansas City, Missouri, 64105 ("DST"), have entered
                     into a separate transfer agent agreement, with respect to
                     the Class D shares of the Portfolio. Under this agreement,
                     DST acts as the transfer agent and dividend disbursing
                     agent (the "Transfer Agent") for the Class D shares of the
                     Trust.

                     Weiss, Peck & Greer, L.L.C., acts as the Portfolio's
                     investment adviser under an advisory agreement with the

                           Janet Fiorenza acts as the portfolio manager for the
                     Portfolio. Ms. Fiorenza, a Principal of the Adviser, has
                     been associated with the Adviser's Tax Exempt Fixed Income
                     group since 1988, and with its predecessor since 1980.
 
                           For its services, the Adviser is entitled to a fee,
                     which is calculated daily and paid monthly, at an annual
                     rate of .05% of the combined average daily net assets of
                     the money market portfolios of the Trust that are advised

                     $500 million to $1 billion, and .03% of such assets in
                     excess of $1 billion. Such fees are allocated daily among

DISTRIBUTION
         _______________________________________________________________________
 
                     SEI Investments Distribution Co. (the "Distributor"), a
                     wholly-owned subsidiary of SEI Investments Company ("SEI
                     Investments"), serves as each Portfolio's distributor
                     pursuant to a distribution agreement (the "Distribution
                     Agreement") with the Trust. The Trust has adopted a
                     distribution plan for its Class D shares (the "Class D
                     Plan,"), pursuant to Rule 12b-1 under the 1940 Act.
 
                           The Class D Plan provides for payments to the
                     Distributor at an annual rate of .25% of the Portfolio's
                     average daily net assets attributable to Class D shares.
                     This payment may be used to compensate financial
                     institutions that provide distribution-related services to
                     their customers. These payments are characterized as
                     "compensation," and are not directly tied to expenses
                     incurred by the Distributor; the payments the Distributor
                     receives during any year may therefore be higher or lower
                     than its actual expenses. These payments compensate the
                     Distributor for its services in connection with
                     distribution assistance or provision of shareholder
                     services, and some or all of it may be used to pay
                     financial institutions and intermediaries such as banks,
                     savings and loan associations, insurance companies, and
                     investment counselors, broker-dealers (including the
                     Distributor's affiliates and subsidiaries) for services or
                     reimbursement of expenses incurred in connection with
                     distribution assistance or provision of shareholder
                     services. If the Distributor's expenses are less than its
                     fees under the Class D Plan, the Trust will still pay the
                     full fee and the Distributor will realize a profit, but the
                     Trust will not be obligated to pay in excess of the full
                     fee, even if the Distributor's actual expenses are higher.
 
                           It is possible that an institution may offer
                     different classes of shares to its customers and thus
                     receive different compensation with respect to different
                     classes. These financial institutions may also charge
                     separate fees to their customers.
 
                           The Trust may execute brokerage or other agency
                     transactions through the Distributor for which the
                     Distributor may receive compensation.
 
                           The Distributor may, from time to time and at its own
                     expense, provide promotional incentives, in the form of
                     cash or other compensation to certain financial
                     institutions whose representatives have sold or are
                     expected to sell significant amounts of the Portfolio's
                     shares.
PERFORMANCE
          ______________________________________________________________________
 
                     From time to time the Portfolio advertises its "current
                     yield," "tax equivalent yield" and "effective yield." These
                     figures are based on historical earnings and are not
                     intended to indicate future performance. The "current
                     yield" of the Portfolio refers to the income generated by
                     an investment over a seven-day period which is then
                     "annualized." That is, the amount of income generated by
                     the investment during the 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" (also
                     called "effective compound yield") is calculated similarly
                     but, when annualized, the income earned by an investment is
                     assumed to be
 
                                                                              13

                     reinvested. The "effective yield" will be slightly higher
                     than the "current yield" because of the compounding effect
                     of this assumed reinvestment. The "tax equivalent yield" is
                     calculated by determining the rate of return that would
                     have been achieved on a fully taxable investment to produce
                     the after-tax equivalent of the Portfolio's yield, assuming
                     certain tax brackets for a shareholder.
 
                           The Portfolio may periodically compare its
                     performance to that of: (i) other mutual funds tracked by
                     mutual fund rating services (such as Lipper Analytical),
                     financial and business publications and periodicals; (ii)
                     broad groups of comparable mutual funds; (iii) unmanaged
                     indices which may assume investment of dividends but
                     generally do not reflect deductions for administrative and
                     management costs; or (iv) other investment alternatives.
                     The Portfolio may also quote financial and business
                     publications and periodicals as they relate to fund
                     management, investment philosophy and investment
                     techniques.
 
                           The performance of Class D shares will normally be
                     lower than that of Class A shares of the Portfolio because
                     of the additional distribution and transfer agent expenses
                     charged to Class D shares.
TAXES
  ______________________________________________________________________________
 
                     The following summary of federal income tax consequences is
                     based on current tax laws and regulations, which may be
                     changed by legislative, judicial or administrative action.
                     No attempt has been made to present a detailed explanation
                     of the federal income tax treatment of the
                     Portfolio or its shareholders,
                     and state and local tax
                     consequences of an investment in
                     the Portfolio may differ from
                     the federal income tax
                     consequences described below.
                     Accordingly, shareholders are
                     urged to consult their tax
                     advisers regarding specific
                     questions as to federal, state
                     and local income taxes.
                     Additional information
                     concerning taxes is set forth in
                     the Statement of Additional
                     Information.
TAX STATUS OF THE
PORTFOLIO:
                     The Portfolio is treated as a separate entity for federal
                     income tax purposes and is not combined with the Trust's
                     other portfolios. The Portfolio intends to continue to
                     qualify for the special tax treatment afforded regulated
                     investment companies under Subchapter M of the Internal
                     Revenue Code of 1986, as amended, (the "Code"), so as to be
                     relieved of federal income tax on net investment company
                     taxable income and net capital gain (the excess of net
                     long-term capital gain over net short-term capital loss)
                     distributed to shareholders.

TAX STATUS OF
DISTRIBUTIONS:
                     The Portfolio intends to
                     distribute substantially all of
                     its net investment income
                     (including net short-term
                     capital gain) to shareholders.
                     If, at the close of each quarter
                     of its taxable year, at least
                     50% of the value of the
                     Portfolio's total assets
                     consists of obligations the
                     interest on which is excludable
                     from gross income, the Portfolio
                     may pay "exempt-interest
                     dividends" to its shareholders.
                     Exempt-interest dividends are
                     excludable from a shareholder's
                     gross income for federal income
                     tax purposes but may have
                     certain collateral federal tax
                     consequences, including alternative minimum tax
                     consequences. In addition, the receipt of exempt-interest
                     dividends may cause persons receiving Social Security or
                     Railroad Retirement benefits to be taxable on a portion of
                     such benefits. See the Statement of Additional Information.

[>] DISTRIBUTIONS
THE PORTFOLIO DISTRIBUTES INCOME DIVIDENDS AND CAPITAL GAINS. INCOME DIVIDENDS
REPRESENT THE EARNINGS FROM THE PORTFOLIO'S INVESTMENTS; CAPITAL GAINS
DISTRIBUTIONS OCCUR WHEN INVESTMENTS IN THE PORTFOLIO ARE SOLD FOR MORE THAN THE

 ...........................................................................
 
                           Any dividends paid out of income realized by the
                     Portfolio on taxable securities will be taxable to
                     shareholders as ordinary income (whether received in cash
                     or in additional shares) to the extent of the Portfolio's
                     earnings and profits and will not qualify for the
                     dividends-received deduction for corporate shareholders.
                     Distributions of net capital gains of the Portfolio also
                     will not qualify for the dividends received deduction and
                     will be taxable to shareholders as long-term capital gains
                     whether received in cash or additional shares, and
                     regardless of how long a shareholder has held the shares.
 
                           Dividends declared by the Portfolio in October,
                     November or December of any year and payable to
                     shareholders of record on a date in any such month will be
                     deemed to have been paid by the Portfolio and received by
                     the shareholders on December 31 of that year if paid by the
                     Portfolio at any time during the following January. The
                     Portfolio intends to make sufficient distributions prior to
                     the end of each calendar year to avoid liability for the
                     federal excise tax applicable to regulated investment
                     companies.
 
                           Interest on indebtedness incurred or continued by a
                     shareholder in order to purchase or carry shares of the
                     Portfolio is not deductible for federal income tax purposes
                     to the extent that it relates to exempt-interest dividends
                     distributed to the shareholder during the taxable year.
                     Furthermore, the Portfolio may not be an appropriate
                     investment for persons (including corporations and other
                     business entities) who are "substantial users" (or persons
                     related to "substantial users") of facilities financed by
                     industrial development bonds or private activity bonds.
                     Such persons should consult their tax advisers before
                     purchasing shares.
 
                           The Portfolio will report annually to its
                     shareholders the portion of dividends that is taxable and
                     the portion that is tax-exempt based on income received by
                     the Portfolio during the year to which the dividends
                     relate.
 
                           Each sale, exchange, or redemption of the Portfolio's
                     shares is a taxable transaction to the shareholder.
 
                                                                              15

INFORMATION ABOUT
DOING BUSINESS
WITH US
    ____________________________________________________________________________
 
BUSINESS DAYS
                     You may buy, sell or exchange shares on days on which the
                     New York Stock Exchange is open for business (a "Business
                     Day"). All purchase, exchange and redemption requests
                     received in "good order" will be effective as of the
                     Business Day received by the Transfer Agent (or its
                     authorized agent) as long as the Transfer Agent (or its
                     authorized agent) receives the order and, in the case of a
                     purchase request, payment before 12:30 p.m., Eastern time,
                     for redemption and exchange requests, and prior to the
                     determination of net asset value per share of the Portfolio
                     for purchase requests. Otherwise the purchase will be
                     effective when payment is received. Broker-dealers may have
                     separate arrangements with the Trust regarding the sale of
                     Class D shares of the Portfolio.
 
                           If an exchange request is
                     for shares of a portfolio whose
                     net asset value is calculated as
                     of a time earlier than 2:00
                     p.m., Eastern time, the exchange
                     request will not be effective
                     until the next Business Day.
                     Anyone who wishes to make an
                     exchange must have received a
                     current prospectus of the
                     portfolio into which the
                     exchange is being made before
                     the exchange will be effected.
MINIMUM INVESTMENTS
                     The minimum initial investment
                     in the Portfolio's Class D
                     shares is $1,000; however, the
                     minimum investment may be waived
                     at the Distributor's discretion.
                     All subsequent purchases must be
                     at least $100 ($25 for payroll
                     deductions authorized pursuant
                     to pre-approved payroll
                     deduction plans). The Trust reserves the right to reject a
                     purchase order when the Distributor determines that it is
                     not in the best interest of the Trust or its shareholders
                     to accept such order.

MAINTAINING A MINIMUM
ACCOUNT BALANCE
                     Due to the relatively high cost of handling small
                     investments, the Portfolio reserves the right to redeem, at
                     net asset value, the shares of any shareholder if, because
                     of redemptions of shares by or on behalf of the
                     shareholder, the account of such shareholder in the
                     Portfolio has a value of less than $1,000, the minimum
                     initial purchase amount. Accordingly, an investor
                     purchasing shares of the Portfolio in only the minimum
                     investment amount may be subject to such involuntary
                     redemption if he or she thereafter redeems any of these
                     shares. Before the Portfolio exercises its right to redeem
                     such shares and to send the proceeds to the shareholder,
                     the shareholder will be given notice that the value of the
                     shares in his or her account is less than the minimum
                     amount and will be allowed 60 days to make an additional
                     investment in the Portfolio in an amount that will increase
 
                                                                              16
<PAGE>
                     the value of the account to at least $1,000. See "Purchase
                     and Redemption of Shares" in the Statement of Additional
                     Information for examples of when the right of redemption
                     may be suspended.
 
                           At various times, the Portfolio may receive a request
                     to redeem shares for which it has not yet received good
                     payment. In such circumstances, redemption proceeds will be
                     forwarded upon collection of payment for the shares;
                     collection of payment may take up to 15 days. The Portfolio
                     intends to pay cash for all shares redeemed, but under
                     abnormal conditions that make payment in cash unwise,
                     payment may be made wholly or partly in portfolio
                     securities with a market value equal to the redemption
                     price. In such cases, an investor may incur brokerage costs
                     in converting such securities to cash.
NET ASSET VALUE
                     An order to buy shares will be executed at a per share
                     price equal to the net asset value next determined after
                     the receipt of the purchase order by the Transfer Agent
                     (the "offering price"). The purchase price of shares is
                     expected to remain constant at $1.00. No certificates
                     representing shares will be issued. An order to sell shares
                     will be executed at the net asset value per share next
                     determined after receipt and effectiveness of a request for
                     redemption in good order. Net asset value per share is
                     determined daily as of 2:00 p.m., Eastern time, on any
                     Business Day. Payment to shareholders for shares redeemed
                     will be made within 7 days after receipt by the Transfer
                     Agent (or its authorized agent) of the redemption order.
 
HOW THE NET ASSET VALUE
IS
DETERMINED
                     The net asset value per share of the Portfolio is
                     determined by dividing the total market value of its
                     investments and other assets, less any liabilities, by the
                     total number of outstanding shares of the Portfolio. The
                     Portfolio's investments will be valued by the amortized
                     cost method described in the Statement of Additional
                     Information. Although the methodology and procedures for
                     determining net asset value per share are identical for
                     each class of the Portfolio, the net asset value per share
                     of one class may differ from that of another class because
                     of the different distribution fees and incremental transfer
                     agent fees charged to Class D shares.
SIGNATURE GUARANTEES
                     The Transfer Agent may require that the signatures on the
                     written request be guaranteed. You should be able to obtain
                     a signature guarantee from a bank, broker, dealer, certain
                     credit unions, securities exchange or association, clearing
                     agency or savings association. Notaries public cannot
                     guarantee signatures. The signature guarantee requirement
                     will be waived if all of the following conditions apply:
                     (1) the redemption is for not more than $5,000 worth of
                     shares, (2) the redemption check is payable to the
                     shareholder(s) of record, and (3) the redemption check is
                     mailed to the shareholder(s) at his or her address of
                     record. The Trust and the Transfer Agent reserve the right
                     to amend these requirements without notice.
TELEPHONE/WIRE
INSTRUCTIONS
                     Redemption orders may be placed by telephone. Neither the
                     Trust nor the Transfer Agent will be responsible for any
                     loss, liability, cost or expense for acting upon wire
                     instructions
 
                                                                              17

                     or upon telephone instructions that it reasonably believes
                     to be genuine. The Trust and the Transfer Agent will each
                     employ reasonable procedures to confirm that instructions
                     communicated by telephone are genuine, including requiring
                     a form of personal identification prior to acting upon
                     instructions received by telephone and recording telephone
                     instructions. If market conditions are extraordinarily
                     active, or other extraordinary circumstances exist, and you
                     experience difficulties placing redemption orders by
                     telephone, you may wish to consider placing your order by
                     other means.
SYSTEMATIC WITHDRAWAL
PLAN ("SWP")
                     Please note that if withdrawals exceed income dividends,
                     your invested principal in the account will be depleted.
                     Thus, depending upon the frequency and amounts of the
                     withdrawal payments and/or any fluctuations in the net
                     asset value per share, your original investment could be
                     exhausted entirely. To participate in the SWP, you must
                     have your dividends automatically reinvested. You may
                     change or cancel the SWP at any time, upon written notice
                     to the Transfer Agent.
HOW TO CLOSE YOUR
ACCOUNT
                     An account may be closed by providing written notice to the
                     Transfer Agent. You may also close your account by
                     telephone if you have previously elected telephone options
                     on your account application.
 
GENERAL INFORMATION
         _______________________________________________________________________
 
THE TRUST
                     SEI Tax Exempt Trust (the"Trust") was organized as a
                     Massachusetts business trust under a Declaration of Trust
                     dated March 15, 1982. The Declaration of Trust permits the
                     Trust to offer separate portfolios of shares and different
                     classes of each portfolio. Shareholders may purchase shares
                     in the Portfolio through two separate classes: Class A and
                     Class D, which provide for variation in distribution and
                     transfer agent costs, voting rights, and dividends. This
                     Prospectus offers Class D shares of the Trust's Tax Free
                     Portfolio. In addition to the Portfolio, the Trust consists
                     of the following portfolios: Institutional Tax Free
                     Portfolio, California Tax Exempt Portfolio,
                     Intermediate-Term Municipal Portfolio, Pennsylvania
                     Municipal Portfolio, New York Intermediate-Term Municipal
                     Portfolio and Pennsylvania Tax Free Portfolio. Additional
                     information pertaining to the Trust may be obtained by
                     writing to SEI Fund Management, Oaks, Pennsylvania 19456,
                     or by calling 1-800-437-6016. All consideration received by
                     the Trust for shares of any portfolio and all assets of
                     such portfolio belong to that portfolio and would be
                     subject to liabilities related thereto.
 
                           The Trust pays its expenses, including fees of its
                     service providers, audit and legal expenses, expenses of
                     preparing prospectuses, proxy solicitation material and
                     reports to shareholders, costs of custodial services and
                     registering the shares under federal and state securities
                     laws, pricing, insurance expenses, litigation and other
                     extraordinary expenses, brokerage costs, interest charges,
                     taxes and organization expenses.
 
                                                                              18

TRUSTEES OF THE TRUST
                     The management and affairs of the Trust are supervised by
                     the Trustees under the laws of the Commonwealth of
                     Massachusetts. The Trustees have approved contracts under
                     which, as described above, certain companies provide
                     essential management services to the Trust.
VOTING RIGHTS
                     Each share held entitles the shareholder of record to one
                     vote. The shareholders of each portfolio or class of the
                     Trust will vote separately on matters relating solely to
                     that portfolio or class, such as any distribution plan. As
                     a Massachusetts business trust, the Trust is not required
                     to hold annual meetings of shareholders, but shareholder
                     approval will be sought for certain changes in the
                     operation of the Trust and for the election of Trustees
                     under certain circumstances. In addition, a Trustee may be
                     removed by the remaining Trustees or by shareholders at a
                     special meeting called upon written request of shareholders
                     owning at least 10% of the outstanding shares of the Trust.
                     In the event that such a meeting is requested, the Trust
                     will provide appropriate assistance and information to the
                     shareholders requesting the meeting.
REPORTING
                     The Trust issues unaudited financial statements
                     semi-annually and audited financial statements annually.
                     The Trust furnishes proxy statements and other reports to
                     shareholders of record.
SHAREHOLDER INQUIRIES
                     Shareholder inquiries should be directed to the Transfer
                     Agent, DST Systems, Inc., 1004 Baltimore Avenue, Kansas
                     City, Missouri, 64141-6240.
DIVIDENDS
                     The net investment income (exclusive of capital gains) of
                     the Portfolio is determined and declared on each Business
                     Day as a dividend for shareholders of record as of the
                     close of business on that day. Dividends are paid by the
                     Portfolio in cash or in additional shares at the discretion
                     of the shareholder on the first Business Day of each month.
                     Currently, capital gains, if any, are distributed at the
                     end of the calendar year.
 
                           The dividends on Class D shares of the Portfolio will
                     normally be lower than those on Class A shares because of
                     the additional distribution and transfer agent expenses
                     charged to Class D shares.
 
                           Shareholders automatically receive all income
                     dividends and capital gain distributions in additional
                     shares, unless the shareholder has elected to take such
                     payment in cash. Shareholders may change their election by
                     providing written notice to the Manager at least 15 days
                     prior to the distribution.
COUNSEL AND INDEPENDENT
PUBLIC ACCOUNTANTS
                     Morgan, Lewis & Bockius LLP serves as counsel to the Trust.
                     Arthur Andersen LLP serves as the independent public
                     accountants of the Trust.
CUSTODIAN AND WIRE AGENT
                     CoreStates Bank, N.A., Broad and Chestnut Streets, P.O. Box
                     7618, Philadelphia, Pennsylvania 19101, serves as custodian
                     of the Trust's assets and acts as wire agent of the Trust.
                     The Custodian holds cash, securities and other assets of
                     the Trust as required by the 1940 Act.

DESCRIPTION OF
PERMITTED
INVESTMENTS AND RISK
FACTORS   ______________________________________________________________________
 
                     The following is a description of certain of the permitted
                     investments for the Portfolio, and the associated risk
                     factors:
MONEY MARKET SECURITIES
                     Money market securities are high-quality,
                     dollar-denominated, short-term debt instruments. They
                     consist of: (i) bankers' acceptances, certificates of
                     deposits, notes and time deposits of highly-rated U.S.
                     banks; (ii) U.S. Treasury obligations and obligations
                     issued by the agencies and instrumentalities of the U.S.
                     Government; and (iii) repurchase agreements involving any
                     of the foregoing obligations entered into with highly-rated
                     banks and broker-dealers.
MUNICIPAL SECURITIES
                     Municipal Securities consist of (i) debt obligations issued
                     by or on behalf of public authorities to obtain funds to be
                     used for various public facilities, for refunding
                     outstanding obligations, for general operating expenses and
                     for lending such funds to other public institutions and
                     facilities, and (ii) certain private activity and
                     industrial development bonds issued by or on behalf of
                     public authorities to obtain funds to provide for the
                     construction, equipment, repair or improvement of privately
                     operated facilities.
 
                           General obligation bonds are backed by the taxing
                     power of the issuing municipality. Revenue bonds are backed
                     by the revenues of a project or facility, tolls from a toll
                     bridge, for example. Certificates of participation
                     represent an interest in an underlying obligation or
                     commitment such as an obligation issued in connection with
                     a leasing arrangement. The payment of principal and
                     interest on private activity and industrial development
                     bonds generally is dependent solely on the ability of the
                     facility's user to meet its financial obligations and the
                     pledge, if any, of real and personal property so financed
                     as security for such payment.
 
                           Municipal notes include general obligation notes, tax
                     anticipation notes, revenue anticipation notes, bond
                     anticipation notes, certificates of indebtedness, demand
                     notes and construction loan notes and participation
                     interests in municipal notes. Municipal bonds include
                     general obligation bonds, revenue or special obligation
                     bonds, private activity and industrial development bonds
                     and participation interests in municipal bonds.
REPURCHASE AGREEMENTS
                     Repurchase agreements are arrangements by which a Portfolio
                     obtains a security and simultaneously commits to return the
                     security to the seller at an agreed upon price (including
                     principal and interest) on an agreed upon date within a
                     number of days from the date of purchase. Repurchase
                     agreements are considered loans under the 1940 Act.
STANDBY COMMITMENTS AND
PUTS
                     Securities subject to standby commitments or puts permit
                     the holder thereof to sell the securities at a fixed price
                     prior to maturity. Securities subject to a standby
                     commitment or put may be sold at any time at the current
                     market price. However, unless the standby
 
                                                                              20
<PAGE>
                     commitment or put was an integral part of the security as
                     originally issued, it may not be marketable or assignable;
                     therefore, the standby commitment or put would only have
                     value to the Portfolio owning the security to which it
                     relates. In certain cases, a premium may be paid for a
                     standby commitment or put, which premium will have the
                     effect of reducing the yield otherwise payable on the
                     underlying security. The Portfolio will limit standby
                     commitment or put transactions to institutions believed to
                     present minimal credit risks.
U.S. GOVERNMENT
OBLIGATIONS
                     Obligations issued by the U.S. Treasury or issued or
                     guaranteed by agencies of the U.S. Government and
                     obligations issued or guaranteed by instrumentalities of
                     the U.S. Government. Some of these securities are supported
                     by the full faith and credit of the U.S. Treasury (E.G.,
                     Government National Mortgage Association securities),
                     others are supported by the right of the issuer to borrow
                     from the Treasury (E.G., Federal Farm Credit Bank
                     securities), while still others are supported only by the
                     credit of the instrumentality (E.G., Fannie Mae
                     securities).
VARIABLE AND FLOATING
RATE INSTRUMENTS
                     Certain of the obligations purchased by the Portfolio may
                     carry variable or floating rates of interest and may
                     involve a conditional or unconditional demand feature. Such
                     obligations may include variable amount master demand
                     notes. Such instruments bear interest at rates which are
                     not fixed, but which vary with changes in specified market
                     rates or indices. The interest rates on these securities
                     may be reset daily, weekly, quarterly or at some other
                     interval and may have a floor or ceiling on interest rate
                     changes. There is a risk that the current interest rate on
                     such obligations may not accurately reflect existing market
                     interest rates. A demand instrument with a demand notice
                     period exceeding seven days may be considered illiquid if
                     there is no secondary market for such security.
WHEN-ISSUED AND DELAYED
DELIVERY SECURITIES
                     When-issued or delayed delivery transactions involve the
                     purchase of an instrument with payment and delivery taking
                     place in the future. Delivery of and payment for these
                     securities may occur a month or more after the date of the
                     purchase commitment. The Portfolio will maintain with the
                     custodian a separate account with liquid securities or cash
                     in an amount at least equal to these commitments. The
                     interest rate realized on these securities is fixed as of
                     the purchase date, and no interest accrues to the Portfolio
                     before settlement.
 
                                                                              21

INVESTMENT OBJECTIVE
AND POLICIES
     ___________________________________________________________________________
 
                     The investment objective of the Portfolio is a high level
                     of current income, exempt from both federal and New York
                     state personal income taxes, consistent with the
                     preservation of principal. There can be no assurance that
                     the Portfolio will achieve its investment objective.
 
                           It is a fundamental policy of the Portfolio to
                     invest, under normal conditions, at least 80% of its net
                     assets in municipal securities that produce interest that,
                     in the opinion of bond counsel to the issuers, is exempt
                     from federal income tax (collectively, "Municipal
                     Securities") and is not a preference item for purposes of
                     the federal alternative minimum tax. Under normal
                     conditions, at least 65% of the Portfolio's assets will be
                     invested in municipal obligations the interest on which is
                     exempt from New York State personal income tax. These
                     include municipal obligations issued by the State of New
                     York and its political subdivisions or any agency or
                     instrumentality of either of the foregoing, as well as
                     municipal obligations issued by territories or possessions
                     of the United States.
 
                           Under normal conditions, the Portfolio may invest, in
                     the aggregate, up to 20% of its net assets in (1) Municipal
                     Securities the interest on which is a preference item for
                     purposes of the federal alternative minimum tax (although
                     the Portfolio has no present intention of investing in such
                     securities) and (2) taxable investments. In addition, for
                     temporary defensive purposes when its investment adviser
                     determines that market conditions warrant, the Portfolio
                     may invest up to 100% of its assets in municipal
                     obligations of states other than New York or taxable money
                     market instruments (including repurchase agreements, U.S.
                     Treasury securities and instruments of certain U.S.
                     commercial banks or savings and loan institutions).
 
                           The Portfolio may purchase the following types of
                     municipal obligations, but only if such securities, at the
                     time of purchase, either have the requisite rating or, if
                     not rated, are determined by Weiss, Peck & Greer, L.L.C.
                     (the "Adviser"), to be of comparable quality: (i) municipal
                     bonds rated BBB or better by Standard and Poor's
                     Corporation ("S&P") or Baa or better by Moody's Investors
                     Service, Inc. ("Moody's"); (ii) municipal notes and
                     certificates of participation which are rated at least SP-2
                     by S&P or MIG-2 or VMIG-2 by Moody's; and (iii) tax-exempt
                     commercial paper rated at least A-2 by S&P or Prime-2 by
                     Moody's. Since the Portfolio often purchases securities
                     supported by credit
 
                                                                               3
<PAGE>
                     enhancements from banks and other financial institutions,
                     changes in the credit quality of these institutions could
                     cause losses to the Portfolio and affect its share price.
 
                           The Portfolio currently contemplates that it will not
                     invest more than 25% of its total assets (at market value
                     at the time of purchase) in Municipal Securities, the
                     interest on which is paid from revenues of projects with
                     similar characteristics. This restriction does not apply to
                     Municipal Securities in any of the following categories:
                     public housing authorities; general obligations of states
                     and localities; state and local housing finance authorities
                     or municipal utilities systems.
 
                           In seeking to attain its investment objective, the
                     Portfolio may invest all or any part of its assets in
                     Municipal Securities that are industrial development bonds.
 
                           Normally, the Portfolio will maintain a
                     dollar-weighted average portfolio maturity of five to ten
                     years; however, under certain circumstances this average
                     weighted maturity may fall below five years. There are no
                     restrictions on the maturity of any single instrument in
                     which the Portfolio may invest. The Portfolio's annual
                     portfolio turnover rate is expected to be less than 100%
                     under normal circumstances. See also "Risk Factors."
 
GENERAL INVESTMENT
POLICIES
     ___________________________________________________________________________
 
                     The Portfolio may invest in variable and floating rate
                     obligations, may purchase securities on a "when-issued"
                     basis, and reserves the right to engage in transactions
                     involving standby commitments. The Portfolio may also
                     purchase other types of tax-exempt instruments as long as
                     they are of a quality equivalent to the long-term bond or
                     commercial paper ratings stated above. The Portfolio will
                     not invest more than 15% of its net assets in illiquid
                     securities.
 
                           The taxable money market instruments in which the
                     Portfolio may invest consist of U.S. Treasury obligations;
                     obligations issued or guaranteed by the U.S. Government or
                     by its agencies or instrumentalities, whether or not backed
                     by the full faith and credit of the U.S. Government;
                     obligations of U.S. commercial banks or savings and loan
                     institutions (not including foreign branches of U.S. banks
                     or U.S. branches of foreign banks) which are members of the
                     Federal Reserve System or Federal Deposit Insurance
                     Corporation and which have total assets of $1 billion or
                     more as shown on their last published financial statements
                     at the time of investment; and repurchase agreements
                     involving any of the foregoing obligations.
 
                           For a description of the permitted investments and
                     ratings, see the "Description of Permitted Investments and
                     Risk Factors" and the Statement of Additional Information.
RISK FACTORS
          ______________________________________________________________________
 
                     The Portfolio's concentration in investments in New York
                     Municipal Securities involves greater risks than if their
                     investments were more diversified. These risks result from
 
                                                                               4
<PAGE>
                     (1) amendments to the New York Constitution and other
                     statutes that limit the taxing and spending authority of
                     New York government entities, (2) the general financial
                     condition of the State of New York, and (3) a variety of
                     New York laws and regulations that may affect, directly or
                     indirectly, New York municipal securities. The ability of
                     issuers of Municipal Securities to pay interest on, or
                     repay principal of, Municipal Securities may be impaired as
                     a result. The Portfolio's yield and share price are
                     sensitive to political and economic developments within the
                     State of New York, and to the financial condition of the
                     State, its public authorities, and political subdivisions,
                     particularly the City of New York. In recent years, both
                     the State and the City experienced financial difficulties
                     related to poor economic performance and recurring
                     deficits. The State's credit standing has been, and could
                     be further, reduced, and its ability to provide assistance
                     to its public authorities and political subdivisions has
                     been, and could be, further impaired.
NON-DIVERSIFICATION
                     In addition to the risks described above arising from
                     concentration, investment in the Portfolio, a
                     non-diversified mutual fund, may entail greater risk than
                     would investment in a diversified investment company
                     because the concentration in Municipal Securities of
                     relatively few issuers could result in greater fluctuation
                     in the total market value of the Portfolio's holdings. Any
                     economic, political, or regulatory developments affecting
                     the value of the securities the Portfolio holds could have
                     a greater impact on the total value of the Portfolio's
                     holdings than would be the case if the portfolio securities
                     were diversified among more issuers. The Portfolio intends
                     to comply with the diversification requirements of
                     Subchapter M of the Internal Revenue Code of 1986, as
                     amended (the "Code"). In accordance with these
                     requirements, the Portfolio will not invest more than 5% of
                     its total assets in any one issuer; this limitation applies
                     to 50% of the Portfolio's total assets.
 
INVESTMENT
LIMITATIONS
        ________________________________________________________________________
 
                     The investment objective and investment limitations are
                     fundamental policies of the Portfolio. Fundamental policies
                     cannot be changed with respect to the Trust or the
                     Portfolio without the consent of the holders of a majority
                     of the Trust's or the Portfolio's outstanding shares.
 
                     THE PORTFOLIO MAY NOT:
 
                     1. Purchase any securities which would cause more than 25%
                        of the total assets of the Portfolio, based on current
                        value at the time of such purchase, to be invested in
                        the securities of one or more issuers conducting their
                        principal business activities in the same industry,
                        provided that this limitation does not apply to
                        investments in obligations issued or guaranteed by the
                        U.S. Government or its agencies and instrumentalities or
                        to investments in tax-exempt securities issued by
                        governments or political subdivisions of governments.
 
                                                                               5
<PAGE>
                     2. Borrow money except for temporary or emergency purposes
                        and then only in an amount not exceeding 10% of the
                        value of the total assets of the Portfolio. All
                        borrowings in excess of 5% of the Portfolio's total
                        assets, will be repaid before making additional
                        investments and any interest paid on such borrowings
                        will reduce the income of the Portfolio.
 
                     The foregoing percentage limitations will apply at the time
                     of the purchase of a security. Additional fundamental
                     investment limitations are set forth in the Statement of
                     Additional Information.
THE MANAGER
          ______________________________________________________________________
 
                     SEI Fund Management (the "Manager" and the "Transfer
                     Agent") provides the Trust with overall management
                     services, regulatory reporting, all necessary office space,
                     equipment, personnel and facilities, and serves as
                     institutional transfer agent and dividend disbursing agent.
 
                           For these services, the Manager is entitled to a fee,
                     which is calculated daily and paid monthly, at an annual
                     rate of .39% of the average daily net assets of the
                     Portfolio. In addition, the Manager and Adviser have
                     voluntarily agreed to waive a portion of their fees
                     proportionately in order to limit total operating expenses
                     of the Class A shares of the Portfolio to not more than
                     .55% of the Portfolio's average daily net assets
                     attributable to Class A shares, on an annualized basis.
                     Each of the Manager and the Adviser reserves the right, in
                     its sole discretion, to terminate its waiver at any time.
THE ADVISER
         _______________________________________________________________________
 
                     Weiss, Peck & Greer, L.L.C. ("WPG"), serves as the
                     Portfolio's investment adviser under an advisory agreement
                     with the Trust (the "Advisory Agreement"). Under the
                     Advisory Agreement, the Adviser invests the assets of the
                     Portfolio, and continuously reviews, supervises and
                     administers the Portfolio's investment program. The Adviser
                     is independent of the Manager and discharges its
                     responsibilities subject to the supervision of, and
                     policies set by, the Trustees of the Trust.
 
                           The Adviser is a limited liability company founded as
                     a limited partnership in 1970, and engages in investment
                     management, venture capital management and management
                     buyouts. WPG has been active since its founding in managing

                           S. Blake Miller, CFA, and Nancy J. Neiman act as the
                     portfolio managers for the Portfolio. Mr. Miller, an
                     Associate Principal of WPG, has been associated with WPG's
                     Tax Exempt Fixed Income group since 1988, and its
                     predecessor since 1986. Ms. Neiman, an Associate Principal
                     of WPG, has been associated with WPG's Tax Exempt Fixed
                     Income group since 1988 and its predecessor since 1985.

                           For its services to the New York Intermediate-Term
                     Municipal Portfolio, the Adviser is entitled to a fee,
                     which is calculated daily and paid monthly, at an annual
                     rate of .18% of the combined average daily net assets of
                     the non-money market portfolios of the Trust advised by the
                     Adviser up to $150 million, and .16% of such assets in
                     excess of $150 million. Such fees are allocated daily among
                     these portfolios on the basis of their relative net assets.
                     The Adviser has voluntarily agreed to waive a portion of
                     its fee, as described under "The Manager." As of August 31,
                     1997, the Portfolio had not commenced operations.
 
DISTRIBUTION AND
SHAREHOLDER
SERVICING
      __________________________________________________________________________
 
                     SEI Investments Distribution Co. (the "Distributor"), a
                     wholly-owned subsidiary of SEI Investments Company ("SEI
                     Investments"), serves as the Portfolio's distributor
                     pursuant to a distribution agreement with the Trust.
 
                           The Portfolio has adopted a shareholder servicing
                     plan for Class A shares (the "Service Plan") under which
                     the Distributor is entitled to receive a shareholder
                     servicing fee of up to .25% of average daily net assets
                     attributable to Class A shares. Under the Service Plan, the
                     Distributor may perform, or may compensate other service
                     providers for performing the following shareholder and
                     administrative services; maintaining client accounts;
                     arranging for bank wires; responding to client inquiries
                     concerning services provided on investments; assisting
                     clients in changing dividend options; account designations
                     and addresses; sub-accounting; providing information on
                     share positions to clients; forwarding shareholder
                     communications to clients; processing purchase, exchange
                     and redemption orders; and processing dividend payments.
                     Under the Service Plan, the Distributor may retain as a
                     profit any difference between the fee it receives and the
                     amount it pays to third parties.
 
                           It is possible that an institution may offer
                     different classes of shares to its customers and thus
                     receive different compensation with respect to different
                     classes. These financial institutions may also charge
                     separate fees to their customers.
 
                           The Trust may also execute brokerage or other agency
                     transactions through the Distributor for which the
                     Distributor may receive usual and customary compensation.
 
                           The Distributor may, from time to time and at its own
                     expense, provide promotional incentives, in the form of
                     cash or other compensation to certain financial
                     institutions whose representatives have sold or are
                     expected to sell significant amounts of the Portfolio's
                     shares.
 
                                                                               7

PURCHASE AND
REDEMPTION OF SHARES
    ____________________________________________________________________________
 
                     Financial institutions may acquire shares of the Portfolio
                     for their own account, or as a record owner on behalf of
                     fiduciary, agency or custody accounts, by placing orders
                     with the Transfer Agent (or its authorized agent).
                     Institutions that use certain SEI proprietary systems may
                     place orders electronically through those systems.
                     Financial institutions which purchase shares for the
                     accounts of their customers may impose separate charges on
                     these customers for account services. Financial
                     institutions may impose an earlier cut-off time for receipt
                     of purchase orders directed through them to allow for
                     processing and transmittal of these orders to the Transfer
                     Agent for effectiveness on the same day.
 
                           Shares of the Portfolio may be purchased or redeemed
                     on days on which the New York Stock Exchange is open for
                     business ("Business Days").
 
                           Shareholders who desire to purchase shares for cash
                     must place their orders with the Transfer Agent (or its
                     authorized agent) prior to the determination of net asset
                     value and in accordance with the procedures described below
                     for the order to be accepted on that Business Day. Cash
                     investments must be transmitted or delivered in federal
                     funds to the wire agent by the close of business on the
                     same day the order is placed. The Trust reserves the right
                     to reject a purchase order when the Distributor determines
                     that it is not in the best interest of the Trust and/or
                     shareholders to accept such purchase order.
 
                           Purchases will be made in full and fractional shares
                     of the Portfolio calculated to three decimal places. The
                     Trust will send shareholders a statement of shares owned
                     after each transaction. The purchase price of shares is the
                     net asset value next determined after a purchase order is
                     received and accepted by the Trust. The net asset value per
                     share of the Portfolio is determined by dividing the total
                     value of its investments and other assets, less any
                     liabilities, by the total number of outstanding shares of
                     the Portfolio. Net asset value per share is determined
                     daily as of the close of trading on the New York Stock
                     Exchange (presently 4:00 p.m., Eastern time) on each
                     Business Day.
 
                           Information about the market value of each portfolio
                     security may be obtained by the Manager from an independent
                     pricing service. Securities having maturities of 60 days or
                     less at the time of purchase will be valued using the
                     amortized cost method (described in the Statement of
                     Additional Information), which approximates the securities'
                     market value. The pricing service may use a matrix system
                     to determine valuations of fixed income securities. This
                     system considers such factors as security prices, yields,
                     maturities, call features, ratings and developments
                     relating to specific securities in arriving at valuations.
                     The pricing service may also provide market quotations. The
                     procedures used by the pricing service and its valuations
                     are reviewed by the officers of the Trust under the general
                     supervision of the Trustees. Portfolio securities for which
                     market quotations are available are valued at the last
                     quoted sale price on each Business Day or, if there is no
                     such reported sale, at the most recently quoted bid price.
 
                                                                               8

                           Shareholders who desire to redeem shares of the
                     Portfolio must place their redemption orders with the
                     Transfer Agent (or its authorized agent) prior to the
                     determination of net asset value and in accordance with the
                     procedures described below on any Business Day. The
                     redemption price is the net asset value per share of the
                     Portfolio next determined after receipt by the Transfer
                     Agent of the redemption order. Payment on redemption will
                     be made as promptly as possible and, in any event, within
                     seven days after the redemption order is received.
 
                           Purchase and redemption orders may be placed by
                     telephone. Neither the Trust nor the Transfer Agent will be
                     responsible for any loss, liability, cost or expense for
                     acting upon wire instructions or upon telephone
                     instructions that it reasonably believes to be genuine. The
                     Trust and the Transfer Agent will each employ reasonable
                     procedures to confirm that instructions communicated by
                     telephone are genuine, including requiring a form of
                     personal identification prior to acting upon instructions
                     received by telephone and recording telephone instructions.
 
                           If market conditions are extraordinarily active, or
                     other extraordinary circumstances exist, shareholders may
                     experience difficulties placing redemption orders by
                     telephone, and may wish to consider placing orders by other
                     means.
PERFORMANCE
          ______________________________________________________________________
 
                     From time to time, the Portfolio may advertise yield, total
                     return and tax equivalent yield. These figures will be
                     based on historical earnings and are not intended to
                     indicate future performance.
 
                           The yield of the Portfolio refers to the annualized
                     income generated by a hypothetical investment in the
                     Portfolio over a specified 30-day period. The yield is
                     calculated by assuming that the same amount of income
                     generated by the investment during that period is generated
                     in each 30-day period over one year and is shown as a
                     percentage of the investment.
 
                           The total return of the Portfolio refers to the
                     average compounded rate of return to a hypothetical
                     investment for designated time periods (including, but not
                     limited to, the period from which the Portfolio commenced
                     operations through the specified date), assuming that the
                     entire investment is redeemed at the end of each period and
                     assuming the reinvestment of all dividend and capital gain
                     distributions. The total return of the Portfolio may also
                     be quoted as a dollar amount or on an aggregate basis, an
                     actual basis.
 
                           The tax equivalent yield is calculated by determining
                     the rate of return that would have been achieved on a fully
                     taxable investment to produce the after-tax equivalent of
                     the Portfolio's yield, assuming certain tax brackets for a
                     shareholder.
 
                           The Portfolio may periodically compare its
                     performance to that of: (i) other mutual funds tracked by
                     mutual fund rating services (such as Lipper Analytical),
                     financial and business publications and periodicals; (ii)
                     broad groups of comparable mutual funds; (iii) unmanaged
                     indices which may assume investment of dividends but
                     generally do not reflect deductions for administrative and
                     management costs; or (iv) other investment
 
                                                                               9

                     alternatives. The Portfolio may quote Morningstar, Inc., a
                     service that ranks mutual funds on the basis of
                     risk-adjusted performance, and Ibbotson Associates of
                     Chicago, Illinois, which provides historical returns of the
                     capital markets in the U.S. The Portfolio may use long-term
                     performance of these capital markets to demonstrate general
                     long-term risk versus reward scenarios and could include
                     the value of a hypothetical investment in any of the
                     capital markets. The Portfolio may also quote financial and
                     business publications and periodicals as they relate to
                     fund management, investment philosophy, and investment
                     techniques.
 
                           The Portfolio may quote various measures of
                     volatility and benchmark correlation in advertising and may
                     compare these measures to those of other funds. Measures of
                     volatility attempt to compare historical share price
                     fluctuations or total returns to a benchmark while measures
                     of benchmark correlation indicate how valid a comparative
                     benchmark might be. Measures of volatility and correlation
                     are calculated using averages of historical data and cannot
                     be calculated precisely.
TAXES
  ______________________________________________________________________________
 
                     The following summary of federal, state and local income
                     tax consequences is based on current tax laws and
                     regulations, which may be changed by legislative, judicial
                     or administrative action. No attempt has been made to
                     present a detailed explanation of the federal, state or
                     local income tax treatment of the Portfolio or its
                     shareholders. Accordingly, shareholders are urged to
                     consult their tax advisers regarding specific questions as
                     to federal, state and local income taxes. Additional
                     information concerning taxes is set forth in the Statement
                     of Additional Information.
TAX STATUS OF THE
PORTFOLIO
                     The Portfolio is treated as a separate entity for federal
                     income tax purposes and is not combined with the Trust's
                     other portfolios. The Portfolio intends to continue to
                     qualify for the special tax treatment afforded regulated
                     investment companies under Subchapter M of the Internal
                     Revenue Code of 1986, as amended (the "Code"), so as to be
                     relieved of federal income tax on net investment company
                     taxable income and net capital gain (the excess of net
                     long-term capital gain over net short-term capital loss)
                     distributed to shareholders.
TAX STATUS OF
DISTRIBUTIONS
                     The Portfolio intends to distribute substantially all of
                     its net investment income (including net short-term capital
                     gain) to shareholders. If, at the close of each quarter of
                     its taxable year, at least 50% of the value of the
                     Portfolio's total assets consists of obligations the
                     interest on which is excludable from gross income, the
                     Portfolio may pay "exempt-interest dividends" to its
                     shareholders. Exempt-interest dividends are excludable from
                     a shareholder's gross income for federal income tax
                     purposes but may have certain collateral federal tax
                     consequences including alternative minimum tax
                     consequences. In addition, the receipt of exempt-interest
                     dividends may cause persons receiving Social Security or
                     Railroad Retirement benefits to be taxable on a portion of
                     such benefits. See the Statement of Additional Information.
 
                                                                              10

                           Any dividends paid out of income realized by the
                     Portfolio on taxable securities will be taxable to
                     shareholders as ordinary income (whether received in cash
                     or in additional shares) to the extent of the Portfolio's
                     earnings and profits and will not qualify for the
                     dividends-received deduction for corporate shareholders.
                     Distributions to shareholders of net capital gains of the
                     Portfolio also will not qualify for the dividends received
                     deduction and will be taxable to shareholders as long-term
                     capital gain, whether received in cash or additional
                     shares, and regardless of how long a shareholder has held
                     the shares.
 
                           Dividends declared by the Portfolio in October,
                     November or December of any year and payable to
                     shareholders of record on a date in any such month will be
                     deemed to have been paid by the Portfolio and received by
                     the shareholders on December 31 of that year if paid by the
                     Portfolio at any time during the following January. The
                     Portfolio intends to make sufficient distributions prior to
                     the end of each calendar year to avoid liability for the
                     federal excise tax applicable to regulated investment
                     companies.
 
                           Interest on indebtedness incurred or continued by a
                     shareholder in order to purchase or carry shares of the
                     Portfolio is not deductible for federal income tax purposes
                     to the extent that it relates to exempt-interest dividends
                     distributed to the shareholders during the taxable year.
                     Furthermore, the Portfolio may not be an appropriate
                     investment for persons (including corporations and other
                     business entities) who are "substantial users" (or persons
                     related to "substantial users") of facilities financed by
                     industrial development bonds or private activity bonds.
                     Such persons should consult their tax advisers before
                     purchasing shares.
 
                           The Portfolio will report annually to its
                     shareholders the portion of dividends that is taxable and
                     the portion that is tax-exempt based on income received by
                     the Portfolio during the year to which the dividends
                     relate.
 
                           Each sale, exchange, or redemption of the Portfolio's
                     shares is a taxable transaction to the shareholder.
NEW YORK STATE AND LOCAL
TAXES
                     The following is a general, abbreviated summary of certain
                     of the provisions of the New York tax code presently in
                     effect as they directly govern the taxation of shareholders
                     subject to New York personal income tax. These provisions
                     are subject to change by legislative or administrative
                     action, and any such change may be retroactive.
 
                           Dividends paid by the Portfolio that are derived from
                     interest on Municipal Securities issued by New York State
                     and the political subdivisions or any agency or
                     instrumentality thereof which interest would be exempt from
                     New York State tax if held by an individual, will be exempt
                     from New York State and New York City personal income
                     taxes, but not corporate franchise taxes. Other dividends
                     and distributions from other Municipal Securities, U.S.
                     Government obligations, taxable income and capital gains
                     will not be exempt from New York State and New York City
                     taxes. In addition, interest or indebtedness incurred by a
                     shareholder to purchase or carry shares of the Portfolio is
                     not deductible for New York personal income tax purposes to
                     the extent that it relates to New York exempt-interest
                     dividends distributed to a shareholder during the taxable
                     year.
 
                                                                              11

GENERAL INFORMATION
         _______________________________________________________________________
THE TRUST
                     The Trust was organized as a Massachusetts business trust
                     under a Declaration of Trust dated March 15, 1982. The
                     Declaration of Trust permits the Trust to offer separate
                     portfolios of shares and different classes of each
                     portfolio. In addition to the Portfolio, the Trust consists
                     of the following portfolios: Tax Free Portfolio,
                     Institutional Tax Free Portfolio, California Tax Exempt
                     Portfolio, Pennsylvania Municipal Portfolio,
                     Intermediate-Term Municipal Portfolio, and Pennsylvania Tax
                     Free Portfolio. All consideration received by the Trust for
                     shares of any portfolio and all assets of such portfolio
                     belong to that portfolio and would be subject to
                     liabilities related thereto.
 
                           The Trust pays its expenses, including fees of its
                     service providers, audit and legal expenses, expenses of
                     preparing prospectuses, proxy solicitation material and
                     reports to shareholders, costs of custodial services and
                     registering the shares under federal and state securities
                     laws, pricing, insurance expenses, litigation and other
                     extraordinary expenses, brokerage costs, interest charges,
                     taxes and organization expenses.
TRUSTEES OF THE TRUST
                     The management and affairs of the Trust are supervised by
                     the Trustees under the laws of the Commonwealth of
                     Massachusetts. The Trustees have approved contracts under
                     which, as described above, certain companies provide
                     essential management services to the Trust.
VOTING RIGHTS
                     Each share held entitles the shareholder of record to one
                     vote. The shareholders of each portfolio or class will vote
                     separately on matters relating solely to that portfolio or
                     class, such as any distribution plan. As a Massachusetts
                     business trust, the Trust is not required to hold annual
                     meetings of shareholders, but approval will be sought for
                     certain changes in the operation of the Trust and for the
                     election of Trustees under certain circumstances. In
                     addition, a Trustee may be removed by the remaining
                     Trustees or by shareholders at a special meeting called
                     upon written request of shareholders owning at least 10% of
                     the outstanding shares of the Trust. In the event that such
                     a meeting is requested, the Trust will provide appropriate
                     assistance and information to the shareholders requesting
                     the meeting.
REPORTING
                     The Trust issues unaudited financial statements
                     semi-annually and audited financial statements annually.
                     The Trust furnishes proxy statements and other reports to
                     shareholders of record.
SHAREHOLDER INQUIRIES
                     Shareholder inquiries should be directed to the Manager,
                     SEI Fund Management, Oaks, Pennsylvania, 19456.
DIVIDENDS
                     Substantially all of the net investment income (exclusive
                     of capital gains) of the Portfolio is periodically declared
                     and paid as a dividend. Shareholders of record on the last
                     record date of each period will be entitled to receive the
                     periodic dividend distribution, which is generally paid on
                     the 10th Business day of the following month. If any net
                     capital gains are realized, they will be distributed by the
                     Portfolio annually.
 
                                                                              12
<PAGE>
                           Shareholders automatically receive all income
                     dividends and capital gain distributions in additional
                     shares, unless the shareholder has elected to take such
                     payment in cash. Shareholders may change their election by
                     providing written notice to the Manager at least 15 days
                     prior to the distribution.

                     accountants of the Trust.

DESCRIPTION OF
PERMITTED
INVESTMENTS AND
RISK FACTORS
          ______________________________________________________________________
 
                     The following is a description of certain of the permitted
                     investments for the Portfolio, and the associated risk
                     factors:
MONEY MARKET SECURITIES
                     Money market securities are high-quality,
                     dollar-denominated, short-term debt instruments. They
                     consist of: (i) bankers' acceptances, certificates of
                     deposits, notes and time deposits of highly-rated U.S.
                     banks; (ii) U.S. Treasury obligations and obligations
                     issued by the agencies and instrumentalities of the U.S.
                     Government and (iii) repurchase agreements involving any of
                     the foregoing obligations entered into with highly-rated
                     banks and broker-dealers.
MUNICIPAL SECURITIES
                     Municipal Securities consist of (i) debt obligations issued
                     by or on behalf of public authorities to obtain funds to be
                     used for various public facilities, for refunding
                     outstanding obligations, for general operating expenses and
                     for lending such funds to other public institutions and
                     facilities, and (ii) certain private activity and
                     industrial development bonds issued by or on behalf of
                     public authorities to obtain funds to provide for the
                     construction, equipment, repair or improvement of privately
                     operated facilities.
                           General obligation bonds are backed by the taxing
                     power of the issuing municipality. Revenue bonds are backed
                     by the revenues of a project or facility, tolls from a toll
                     bridge, for example. Certificates of participation
                     represent an interest in an underlying obligation or
                     commitment such as an obligation issued in connection with
                     a leasing arrangement. The payment of principal and
                     interest on private activity and industrial development
                     bonds generally is dependent solely on the ability of the
                     facility's user to meet its financial obligations and the
                     pledge, if any, of real and personal property so financed
                     as security for such payment.
                           Municipal notes include general obligation notes, tax
                     anticipation notes, revenue anticipation notes, bond
                     anticipation notes, certificates of indebtedness, demand
                     notes and construction loan notes and participation
                     interests in municipal notes. Municipal bonds
 
                                                                              13
<PAGE>
                     include general obligation bonds, revenue or special
                     obligation bonds, private activity and industrial
                     development bonds and participation interests in municipal
                     bonds.
REPURCHASE AGREEMENTS
                     Repurchase agreements are arrangements by which a Portfolio
                     obtains a security and simultaneously commits to return the
                     security to the seller at an agreed upon price (including
                     principal and interest) on an agreed upon date within a
                     number of days from the date of purchase. Repurchase
                     agreements are considered loans under the 1940 Act.
STANDBY COMMITMENTS
AND PUTS
                     Securities subject to standby commitments or puts permit
                     the holder thereof to sell the securities at a fixed price
                     prior to maturity. Securities subject to a standby
                     commitment or put may be sold at any time at the current
                     market price. However, unless the standby commitment or put
                     was an integral part of the security as originally issued,
                     it may not be marketable or assignable; therefore, the
                     standby commitment or put would only have value to the
                     Portfolio owning the security to which it relates. In
                     certain cases, a premium may be paid for a standby
                     commitment or put, which premium will have the effect of
                     reducing the yield otherwise payable on the underlying
                     security. The Portfolio will limit standby commitment or
                     put transactions to institutions believed to present
                     minimal credit risks.
U.S. GOVERNMENT
OBLIGATIONS
                     Obligations issued by the U.S. Treasury or issued or
                     guaranteed by agencies of the U.S. Government and
                     obligations issued or guaranteed by instrumentalities of
                     the U.S. Government. Some of these securities are supported
                     by the full faith and credit of the U.S. Treasury (E.G.,
                     Government National Mortgage Association securities),
                     others are supported by the right of the issuer to borrow
                     from the Treasury (E.G., Federal Farm Credit Bank
                     securities), while still others are supported only by the
                     credit of the instrumentality (E.G., Fannie Mae
                     securities).
VARIABLE AND FLOATING
RATE INSTRUMENTS
                     Certain of the obligations purchased by the Portfolio may
                     carry variable or floating rates of interest and may
                     involve a conditional or unconditional demand feature. Such
                     obligations may include variable amount master demand
                     notes. Such instruments bear interest at rates which are
                     not fixed, but which vary with changes in specified market
                     rates or indices. The interest rates on these securities
                     may be reset daily, weekly, quarterly or at some other
                     interval, and may have a floor or ceiling on interest rate
                     changes. There is a risk that the current interest rate on
                     such obligations may not accurately reflect existing market
                     interest rates. A demand instrument with a demand notice
                     period exceeding seven days may be considered illiquid if
                     there is no secondary market for such security.
WHEN-ISSUED AND DELAYED
DELIVERY SECURITIES
                     When-issued or delayed delivery transactions involve the
                     purchase of an instrument with payment and delivery taking
                     place in the future. Delivery of and payment for these
                     securities may occur a month or more after the date of the
                     purchase commitment. The Portfolio will maintain with the
                     custodian a separate account with liquid securities or cash
                     in an amount at least equal to these commitments. The
                     interest rate realized on these securities is fixed as of
                     the purchase date, and no interest accrues to the Portfolio
                     before settlement.
 
                                                                              14

INVESTMENT OBJECTIVE
AND POLICIES
     ___________________________________________________________________________
 
                     The Portfolio's investment objective is to preserve
                     principal value and maintain a high degree of liquidity
                     while providing current income exempt from federal income
                     taxes. There can be no assurance that the Portfolio will
                     meet its investment objective.
 
                           The Portfolio invests in U.S. dollar denominated
                     municipal securities of issuers located in all fifty
                     states, the District of Columbia, Puerto Rico and other
                     U.S. territories and possessions (collectively, "Municipal
                     Securities"). It is a fundamental policy of the Portfolio
                     to invest at least 80% of its net assets in securities the
                     interest on which is exempt from federal income taxes,
                     based on opinions from bond counsel for the issuers, and
                     the Portfolio will invest, under normal conditions, at
                     least 80% of its net assets in securities the interest on
                     which is not a preference item for purposes of the federal
                     alternative minimum tax.
 
                           The Portfolio may purchase municipal bonds, municipal
                     notes and tax-exempt commercial paper, but only if such
                     securities, at the time of purchase, meet quality, maturity
                     and diversification requirements imposed by Rule 2a-7. See
                     "General Investment Policies."
 
                           The Adviser will not invest more than 25% of
                     Portfolio assets in Municipal Securities (a) whose issuers
                     are located in the same state or (b) the interest on which
                     is derived from revenues of similar type projects. This
                     restriction does not apply to Municipal Securities in any
                     of the following categories: public housing authorities;
                     general obligations of states and localities; state and
                     local housing finance authorities or municipal utilities
                     systems.
 
                           There could be economic, business, or political
                     developments which might affect all Municipal Securities of
                     a similar type. To the extent that a significant portion of
                     the Portfolio's assets are invested in Municipal Securities
                     payable from revenues on similar projects, the Portfolio
                     will be subject to the peculiar risks presented by such
                     projects to a
 
                                                                               4
<PAGE>
                     greater extent than it would be if the Portfolio's assets
                     were not so invested. Moreover, in seeking to attain its
                     investment objective, the Portfolio may invest all or any
                     part of its assets in Municipal Securities that are
                     industrial development bonds.
 
GENERAL INVESTMENT
POLICIES
     ___________________________________________________________________________
 
                     In purchasing obligations, the Portfolio complies with the
                     requirements of Rule 2a-7 under the Investment Company Act
                     of 1940 (the "1940 Act"), as that Rule may be amended from
                     time to time. These requirements currently provide that the
                     Portfolio must limit its investments to securities with
                     remaining maturities of 397 days or less, and must maintain
                     a dollar-weighted average maturity of 90 days or less. In
                     addition, the Portfolio may only invest in eligible
                     securities. In general, this means securities rated in one
                     of the two highest categories for short-term securities by
                     at least two nationally recognized statistical rating
                     organizations ("NRSROs") (or by one NRSRO if only one NRSRO
                     has rated the security), or, if unrated, determined by
                     Weiss, Peck & Greer, L.L.C. (the "Adviser") to be of
                     equivalent quality. Since the Portfolio often purchases
                     securities supported by credit enhancements from banks and
                     other financial institutions, changes in the credit quality
                     of these institutions could cause losses to the Portfolio
                     and affect its share price.
 
                           Securities rated in the highest rating category
                     (e.g., A-1 by Standard & Poor's Corporation ("S&P")) by at
                     least two NRSROs (or, if unrated, determined by the Adviser
                     to be of comparable quality) are "first tier" securities.
                     Non-first tier securities rated in the second highest
                     rating category (e.g., A-2 by S&P) by at least one NRSRO
                     (or, if unrated, determined by the Adviser to be of
                     comparable quality) are considered to be "second tier"
                     securities. The Portfolio's investments in non-first tier
                     conduit securities will be limited to 5% of the Portfolio's
                     assets. Conduit securities are securities issued to finance
                     non-governmental private projects, such as housing
                     developments and retirement homes, and for which the
                     ultimate obligor is not a governmental issuer.
 
                           The Portfolio may purchase securities on a
                     "when-issued" basis, variable and floating rate obligations
                     and reserves the right to engage in transactions involving
                     standby commitments. While the Portfolio generally intends
                     to be fully invested in federally tax-exempt securities,
                     the Portfolio may invest up to 20% of its net assets in
                     taxable money market instruments (including repurchase
                     agreements) and securities the interest on which is a
                     preference item for purposes of the federal alternative
                     minimum tax. The Portfolio will not invest more than 10% of
                     its total assets in securities which are considered to be
                     illiquid.

                     ratings, see the "Description of Permitted Investments and

INVESTMENT
LIMITATIONS
        ________________________________________________________________________
 
                     The investment objective and investment limitations are
                     fundamental policies of the Portfolio. Fundamental policies
                     cannot be changed with respect to the Trust or the
                     Portfolio without the consent of the holders of a majority
                     of the Trust's or the Portfolio's outstanding shares. It is
                     a fundamental policy of the Portfolio to use its best
                     efforts to maintain a constant net asset value of $1.00 per
                     share.
 
                     THE PORTFOLIO MAY NOT:
 
                     1. Purchase securities of any issuer (except securities
                        issued or guaranteed by the United States Government,
                        its agencies or instrumentalities) if, as a result, more
                        than 5% of the total assets of the Portfolio (based on
                        current market value at the time of investment) would be
                        invested in the securities of such issuer; provided,
                        however, that the Portfolio may invest up to 25% of its
                        total assets without regard to this restriction of, and
                        as permitted by, Rule 2a-7.
 
                     2. Purchase any securities which would cause more than 25%
                        of the total assets of the Portfolio, based on current
                        value at the time of such purchase, to be invested in
                        the securities of one or more issuers conducting their
                        principal business activities in the same industry,
                        provided that this limitation does not apply to
                        investments in obligations issued or guaranteed by the
                        U.S. Government or its agencies and instrumentalities.
 
                     3. Borrow money except for temporary or emergency purposes,
                        and then only in an amount not exceeding 10% of the
                        value of the total assets of the Portfolio. All
                        borrowings will be repaid before making additional
                        investments and any interest paid on such borrowings
                        will reduce the income of the Portfolio.
 
                     The foregoing percentage limitations will apply at the time
                     of the purchase of a security. Additional fundamental
                     investment limitations are set forth in the Statement of
                     Additional Information.
THE MANAGER
          ______________________________________________________________________
 
                     SEI Fund Management (the "Manager" and the "Transfer
                     Agent") provides the Trust with overall management
                     services, regulatory reporting, all necessary office space,
                     equipment, personnel and facilities, and serves as
                     institutional transfer agent and dividend disbursing agent.
 
                           For these services, the Manager is entitled to a fee,
                     which is calculated daily and paid monthly, at an annual
                     rate of .36% of the average daily net assets of the
                     Portfolio. The Manager has voluntarily agreed to waive a
                     portion of its fee in order to limit the total operating
                     expenses to not more than .33% of the average daily net
                     assets of the Class A
 
                                                                               6
<PAGE>
                     shares of the Portfolio and not more than .63% of the
                     average daily net assets of the Class B shares of the
                     Portfolio, on an annualized basis. The Manager reserves the
                     right, in its sole discretion, to terminate this voluntary
                     fee waiver at any time. For the fiscal year ended August
                     31, 1997, the Portfolio paid management fees, after
                     waivers, of .25% of its average daily net assets.
THE ADVISER
         _______________________________________________________________________
 
                     Weiss, Peck & Greer, L.L.C., serves as the Portfolio's
                     investment adviser under an investment advisory agreement
                     with the Trust (the "Advisory Agreement"). Under the
                     Advisory Agreement, the Adviser invests the assets of the
                     Portfolio, and continuously reviews, supervises and
                     administers the Portfolio's investment program. The Adviser
                     is independent of the Manager and discharges its
                     responsibilities subject to the supervision of, and
                     policies set by, the Trustees of the Trust.
 
                           The Adviser is a limited liability company founded as
                     a limited partnership in 1970, and engages in investment
                     management, venture capital management and management
                     buyouts. The Adviser has been active since its founding in
                     managing portfolios of tax exempt securities. As of
                     September 30, 1997, total assets under management were
                     approximately $14.6 billion. The principal business address
                     of the Adviser is One New York Plaza, New York, New York
                     10004.
 
                           Janet Fiorenza acts as the portfolio manager for the
                     Portfolio. Ms. Fiorenza, a Principal of the Adviser, has
                     been associated with the Adviser's Tax Exempt Fixed Income
                     group since 1988, and with its predecessor since 1980.
 
                           For its services, the Adviser is entitled to a fee,
                     which is calculated daily and paid monthly, at an annual
                     rate of .05% of the combined average daily net assets of
                     the money market portfolios of the Trust that are advised
                     by the Adviser up to $500 million, .04% of such assets from
                     $500 million to $1 billion and .03% of such assets in
                     excess of $1 billion. Such fees are allocated daily among
                     these portfolios based on their relative net assets. For
                     the fiscal year ended August 31, 1997 the Portfolio paid
                     advisory fees, after waivers, of .04% of its relative net
                     assets.
 
                                                                               7

SERVICING
      __________________________________________________________________________
 
                     SEI Investments Distribution Co. (the "Distributor"), a
                     wholly owned subsidiary of SEI Investments Company ("SEI
                     Investments"), serves as the Portfolio's distributor
                     pursuant to a distribution agreement (the "Distribution
                     Agreement") with the Trust.
 
                           The Portfolio has adopted plans under which firms,
                     including the Distributor, that provide shareholder and
                     administrative services may receive compensation therefor.
                     The Class A, B and C plans differ in a number of ways,
                     including the amounts that may be paid. Under each plan,
                     the Distributor may provide those services itself or may
                     enter into arrangements under which third parties provide
                     such services and are compensated by the Distributor. Under
                     such arrangements the Distributor may retain as a profit
                     any difference between the fee it receives and the amount
                     it pays such third party. In addition, the Portfolio may
                     enter into such arrangements directly.
 
                           Under the Class A plan, the Distributor is entitled
                     to receive a fee at an annual rate of up to .25% of the
                     average daily net assets of the Portfolio attributable to
                     Class A shares, in return for provision of a broad range of
                     shareholder and administrative services. Under the Class B
                     shareholder service plan, the Distributor is entitled to
                     receive shareholder service fees at an annual rate of up to
                     .25% of average daily net assets in return for the
                     Distributor's (or its agent's) efforts in maintaining
                     client accounts; arranging for bank wires; responding to
                     client inquiries concerning services provided or
                     investment; and assisting clients in changing dividend
                     options, account designations and addresses. In addition,
                     under its administrative services plan, Class B shares will
                     pay administrative services fees to the Distributor at
                     specified percentages of the average daily net assets of
                     the shares of the Class (up to .05%). Administrative
                     services include sub-accounting; providing information on
                     share positions to clients; forwarding shareholder
                     communications to clients; processing purchase, exchange
                     and redemption orders and processing dividend payments.
 
                           It is possible that an institution may offer
                     different classes of shares to its customers and differing
                     services to the Classes of the Portfolio and thus receive
                     compensation with respect to different classes. These
                     financial institutions may also charge separate fees to
                     their customers.
 
                           The Trust may execute brokerage or other agency
                     transactions through the Distributor for which the
                     Distributor may receive compensation.
 
                           The Distributor may, from time to time and at its own
                     expense, provide promotional incentives, in the form of
                     cash or other compensation, to certain financial
                     institutions whose representatives have sold or are
                     expected to sell significant amounts of the Portfolio's
                     shares.
 
                                                                               8

PURCHASE AND
REDEMPTION OF SHARES
    ____________________________________________________________________________
 
                     Financial institutions may acquire shares of the Portfolio
                     for their own account, or as a record owner on behalf of
                     fiduciary, agency or custody accounts, by placing orders
                     with the Transfer Agent (or its authorized agent).
                     Institutions that use certain SEI proprietary systems may
                     place orders electronically through those systems.
                     Financial institutions which purchase shares for the
                     accounts of their customers may impose separate charges on
                     these customers for account services. Financial
                     institutions may impose an earlier cut-off time for receipt
                     of purchase orders directed through them to allow for
                     processing and transmittal of these orders to the Transfer
                     Agent for effectiveness on the same day.
 
                           Shares of the Portfolio may be purchased or redeemed
                     on days on which the New York Stock Exchange is open for
                     business ("Business Days"). However, money market fund
                     shares cannot be purchased by Federal Reserve wire on
                     federal holidays restricting wire transfers.
 
                           Shareholders who desire to purchase shares for cash
                     must place their orders with the Transfer Agent (or its
                     authorized agent) prior to the determination of net asset
                     value and in accordance with the procedures described below
                     for the order to be accepted on that Business Day. Cash
                     investments must be transmitted or delivered in federal
                     funds to the wire agent by the close of business on the
                     same day the order is placed. The Trust reserves the right
                     to reject a purchase order when the Transfer Agent
                     determines that it is not in the best interest of the Trust
                     or shareholders to accept such purchase order.
 
                           The Trust will send shareholders a statement of
                     shares owned after each transaction. The purchase price of
                     shares is the net asset value next determined after a
                     purchase order is received and accepted by the Trust, which
                     is expected to remain constant at $1.00. The net asset
                     value per share of the Portfolio is determined by dividing
                     the total value of its investments and other assets, less
                     any liabilities, by the total number of outstanding shares
                     of the Portfolio. The Portfolio's investments will be
                     valued by the amortized cost method described in the
                     Statement of Additional Information. Net asset value per
                     share is determined daily as of 2:00 p.m., Eastern time, on
                     each Business Day.
 
                           Shareholders who desire to redeem shares of the
                     Portfolio must place their redemption orders with the
                     Transfer Agent (or its authorized agent) prior to 12:30
                     p.m., Eastern time, on any Business Day. Otherwise, the
                     redemption order will be effective on the next Business
                     Day. The redemption price is the net asset value per share
                     of the Portfolio next determined after receipt by the
                     Transfer Agent, and effectiveness, of the redemption order.
                     For redemption orders received before 12:30 p.m., Eastern
                     time, on any Business Day, payment will be made the same
                     day by transfer of federal funds. Otherwise, the redemption
                     will be effective on the next Business Day.
 
                                                                               9

                           If a shareholder's aggregate balance is less than $45
                     million as a result of redemption or transfer, for a period
                     of seven consecutive days, the Trust reserves the right to
                     redeem that shareholder's shares in the Portfolio for their
                     current net asset value. Before the Trust redeems such
                     shares, the shareholder will be given notice that the value
                     of its shares is less than the minimum amount and will be
                     allowed sixty days to make an additional investment in an
                     amount that will increase the value of the account to at
                     least $50 million.
 
                           Purchase and redemption orders may be placed by
                     telephone. Neither the Trust nor the Transfer Agent will be
                     responsible for any loss, liability, cost or expense for
                     acting upon wire instructions or upon telephone
                     instructions that it reasonably believes to be genuine. The
                     Trust and the Transfer Agent will each employ reasonable
                     procedures to confirm that instructions communicated by
                     telephone are genuine, including requiring a form of
                     personal identification prior to acting upon instructions
                     received by telephone and recording telephone instructions.
 
                           If market conditions are extraordinarily active, or
                     other extraordinary circumstances exist, shareholders may
                     experience difficulties placing redemption orders by
                     telephone, and may wish to consider placing orders by other
                     means.
PERFORMANCE
          ______________________________________________________________________
 
                     From time to time the Portfolio advertises its "current
                     yield," "tax equivalent yield" and "effective yield." These
                     figures are based on historical earnings and are not
                     intended to indicate future performance. The "current
                     yield" of the Portfolio refers to the income generated by
                     an investment over a seven-day period which is then
                     "annualized." That is, the amount of income generated by
                     the investment during the 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" (also
                     called "effective compound yield") is calculated similarly
                     but, when annualized, the income earned by an investment is
                     assumed to be reinvested. The "effective yield" will be
                     slightly higher than the "current yield" because of the
                     compounding effect of this assumed reinvestment. The "tax
                     equivalent yield" is calculated by determining the rate of
                     return that would have been achieved on a fully taxable
                     investment to produce the after-tax equivalent of the
                     Portfolio's yield, assuming certain tax brackets for a
                     shareholder.
 
                           The Portfolio may periodically compare its
                     performance to that of: (i) other mutual funds tracked by
                     mutual fund rating services (such as Lipper Analytical),
                     financial and business publications and periodicals; (ii)
                     broad groups of comparable mutual funds; (iii) unmanaged
                     indices which may assume investment of dividends but
                     generally do not reflect deductions for administrative and
                     management costs; or (iv) other investment alternatives.
                     The Portfolio may also quote financial and business
                     publications and
 
                                                                              10
<PAGE>
                     periodicals as they relate to fund management, investment
                     philosophy and investment techniques.
 
                           The performance of Class A shares will normally be
                     higher than that of Class B and Class C shares because of
                     the additional administrative services expenses charged to
                     Class B and Class C shares.
TAXES
  ______________________________________________________________________________
 
                     The following summary of federal income tax consequences is
                     based on current tax laws and regulations, which may be
                     changed by legislative, judicial or administrative action.
                     No attempt has been made to present a detailed explanation
                     of the federal income tax treatment of the Portfolio or its
                     shareholders, and state and local tax consequences of an
                     investment in the Portfolio may differ from the federal
                     income tax consequences described below. Accordingly,
                     shareholders are urged to consult their tax advisers
                     regarding specific questions as to federal, state and local
                     income taxes. Additional information concerning taxes is
                     set forth in the Statement of Additional Information.
TAX STATUS OF THE
PORTFOLIO
                     The Portfolio is treated as a separate entity for federal
                     income tax purposes and is not combined with the Trust's
                     other portfolios. The Portfolio intends to continue to
                     qualify for the special tax treatment afforded regulated
                     investment companies under Subchapter M of the Internal
                     Revenue Code of 1986, as amended (the "Code"), so as to be
                     relieved of federal income tax on net investment company
                     taxable income and net capital gain (the excess of net
                     long-term capital gain over net short-term capital loss)
                     distributed to shareholders.
TAX STATUS OF
DISTRIBUTIONS
                     The Portfolio intends to distribute substantially all of
                     its net investment income (including net short-term capital
                     gain) to shareholders. If, at the close of each quarter of
                     its taxable year, at least 50% of the value of the
                     Portfolio's total assets consists of obligations the
                     interest on which is excludable from gross income, the
                     Portfolio may pay "exempt-interest dividends" to its
                     shareholders. Exempt-interest dividends are excludable from
                     a shareholder's gross income for federal income tax
                     purposes but may have certain collateral federal tax
                     consequences including alternative minimum tax
                     consequences. In addition, the receipt of exempt-interest
                     dividends may cause persons receiving Social Security or
                     Railroad Retirement benefits to be taxable on a portion of
                     such benefits. See the Statement of Additional Information.
 
                           Any dividends paid out of income realized by the
                     Portfolio on taxable securities will be taxable to
                     shareholders as ordinary income (whether received in cash
                     or in additional shares) to the extent of the Portfolio's
                     earnings and profits and will not qualify for the
                     dividends-received deduction for corporate shareholders.
                     Distributions to shareholders of net capital gains of the
                     Portfolio also will not qualify for the dividends received
                     deduction and will be taxable to shareholders as long-term
                     capital gain, whether received in cash or additional
                     shares, and regardless of how long a shareholder has held
                     the shares.
 
                                                                              11
<PAGE>
                           Dividends declared by the Portfolio in October,
                     November or December of any year and payable to
                     shareholders of record on a date in any such month will be
                     deemed to have been paid by the Portfolio and received by
                     the shareholders on December 31 of that year if paid by the
                     Portfolio at any time during the following January. The
                     Portfolio intends to make sufficient distributions prior to
                     the end of each calendar year to avoid liability for the
                     federal excise tax applicable to regulated investment
                     companies.
 
                           Interest on indebtedness incurred or continued by a
                     shareholder in order to purchase or carry shares of the
                     Portfolio is not deductible for federal income tax purposes
                     to the extent that it relates to exempt-interest dividends
                     distributed to the shareholder during the taxable year.
                     Furthermore, the Portfolio may not be an appropriate
                     investment for persons (including corporations and other
                     business entities) who are "substantial users" (or persons
                     related to "substantial users") of facilities financed by
                     industrial development bonds or private activity bonds.
                     Such persons should consult their tax advisers before
                     purchasing shares.
 
                           The Portfolio will report annually to its
                     shareholders the portion of dividends that is taxable and
                     the portion that is tax-exempt based on income received by
                     the Portfolio during the year to which the dividends
                     relate.
 
                           Each sale, exchange, or redemption of the Portfolio's
                     shares is a taxable transaction to the shareholder.
 
GENERAL INFORMATION
         _______________________________________________________________________
THE TRUST
                     The Trust was organized as a Massachusetts business trust
                     under a Declaration of Trust dated March 15, 1982. The
                     Declaration of Trust permits the Trust to offer separate
                     portfolios of shares and different classes of each
                     portfolio. In addition to the Portfolio, the Trust consists
                     of the following portfolios: Tax Free Portfolio, California
                     Tax Exempt Portfolio, Intermediate-Term Municipal
                     Portfolio, Pennsylvania Municipal Portfolio, New York

                     shares of any portfolio and all assets of such portfolio
                     belong to that portfolio and would be subject to
                     liabilities related thereto.
 
                           The Trust pay its expenses, including fees of its
                     service providers, audit and legal expenses, expenses of
                     preparing prospectuses, proxy solicitation materials and
                     reports to shareholders, costs of custodial services and
                     registering the shares under federal and state securities
                     laws, pricing, insurance expenses, litigation and other
                     extraordinary expenses, brokerage costs, interest charges,
                     taxes and organization expenses.
TRUSTEES OF THE TRUST
                     The management and affairs of the Trust are supervised by
                     the Trustees under the laws of the Commonwealth of
                     Massachusetts. The Trustees have approved contracts under
                     which, as described above, certain companies provide
                     essential services to the Trust.
 
                                                                              12

VOTING RIGHTS
                     Each share held entitles the shareholder of record to one
                     vote. The shareholders of each portfolio or class will vote
                     separately on matters relating solely to that Portfolio or
                     class, such as any distribution plan. As a Massachusetts
                     business trust, the Trust is not required to hold annual
                     meetings of shareholders, but approval will be sought for
                     certain changes in the operation of the Trust and for the
                     election of Trustees under certain circumstances. In
                     addition, a Trustee may be removed by the remaining
                     Trustees or by shareholders at a special meeting called
                     upon written request of shareholders owning at least 10% of
                     the outstanding shares of the Trust. In the event that such
                     a meeting is requested, the Trust will provide appropriate
                     assistance and information to the shareholders requesting
                     the meeting.
REPORTING
                     The Trust issues unaudited financial statements
                     semi-annually and audited financial statements annually.
                     The Trust furnishes proxy statements and other reports to
                     shareholders of record.
SHAREHOLDER INQUIRIES
                     Shareholder inquiries should be directed to the Manager.
                     SEI Fund Management, Oaks, Pennsylvania, 19456.
DIVIDENDS
                     The net investment income (exclusive of capital gains) of
                     the Portfolio is determined and declared on each Business
                     Day as a dividend for shareholders of record as of the
                     close of business on that day. Dividends are paid by the
                     Portfolio in federal funds or in additional shares at the
                     discretion of the shareholder on the first Business Day of
                     each month. Dividends will be paid on the next Business Day
                     to shareholders who redeem all of their shares of the
                     Portfolio at any time during the month. Currently, capital
                     gains, if any, are distributed at the end of the calendar
                     year.
 
                           Shareholders automatically receive all income
                     dividends and capital gain distributions in additional
                     shares, unless the shareholder has elected to take such
                     payment in cash. Shareholders may change their election by
                     providing written notice to the Manager at least 15 days
                     prior to the distribution.
 
                           The dividends on Class A shares of the Portfolio are
                     normally higher than those on Class B and Class C shares
                     because of the additional administrative services expenses
                     charged to Class B and Class C shares.

DESCRIPTION OF
PERMITTED
INVESTMENTS AND RISK
FACTORS   ______________________________________________________________________
 
                     The following is a description of certain of the permitted
                     investments for the Portfolio, and the associated risk
                     factors:
MONEY MARKET SECURITIES
 
                     Money market securities are high-quality,
                     dollar-denominated, short-term debt instruments. They
                     consist of: (i) bankers' acceptances, certificates of
                     deposits, notes and time deposits of highly-rated U.S.
                     banks; (ii) U.S. Treasury obligations and obligations
                     issued by the agencies and instrumentalities of the U.S.
                     Government; and (iii) repurchase agreements involving any
                     of the foregoing obligations entered into with highly-rated
                     banks and broker-dealers.
MUNICIPAL SECURITIES
 
                     Municipal Securities consist of (i) debt obligations issued
                     by or on behalf of public authorities to obtain funds to be
                     used for various public facilities, for refunding
                     outstanding obligations, for general operating expenses and
                     for lending such funds to other public institutions and
                     facilities, and (ii) certain private activity and
                     industrial development bonds issued by or on behalf of
                     public authorities to obtain funds to provide for the
                     construction, equipment, repair or improvement of privately
                     operated facilities.
 
                           General obligation bonds are backed by the taxing
                     power of the issuing municipality. Revenue bonds are backed
                     by the revenues of a project or facility, tolls from a toll
                     bridge, for example. Certificates of participation
                     represent an interest in an underlying obligation or
                     commitment such as an obligation issued in connection with
                     a leasing arrangement. The payment of principal and
                     interest on private activity and industrial development
                     bonds generally is dependent solely on the ability of the
                     facility's user to meet its financial obligations and the
                     pledge, if any, of real and personal property so financed
                     as security for such payment.
 
                           Municipal notes include general obligation notes, tax
                     anticipation notes, revenue anticipation notes, bond
                     anticipation notes, certificates of indebtedness, demand
                     notes and construction loan notes and participation
                     interests in municipal notes. Municipal bonds include
                     general obligation bonds, revenue or special obligation
                     bonds, private activity and industrial development bonds
                     and participation interests in municipal bonds.
REPURCHASE AGREEMENTS
 
                     Repurchase agreements are arrangements by which a Portfolio
                     obtains a security and simultaneously commits to return the
                     security to the seller at an agreed upon price (including
                     principal and interest) on an agreed upon date within a
                     number of days from the date of purchase. Repurchase
                     agreements are considered loans under the 1940 Act.
 
                                                                              14
<PAGE>
STANDBY COMMITMENTS AND
PUTS
 
                     Securities subject to standby commitments or puts permit
                     the holder thereof to sell the securities at a fixed price
                     prior to maturity. Securities subject to a standby
                     commitment or put may be sold at any time at the current
                     market price. However, unless the standby commitment or put
                     was an integral part of the security as originally issued,
                     it may not be marketable or assignable; therefore, the
                     standby commitment or put would only have value to the
                     Portfolio owning the security to which it relates. In
                     certain cases, a premium may be paid for a standby
                     commitment or put, which premium will have the effect of
                     reducing the yield otherwise payable on the underlying
                     security. The Portfolio will limit standby commitment or
                     put transactions to institutions believed to present
                     minimal credit risks.
U.S. GOVERNMENT
OBLIGATIONS
 
                     Obligations issued by the U.S. Treasury or issued or
                     guaranteed by agencies of the U.S. Government and
                     obligations issued or guaranteed by instrumentalities of
                     the U.S. Government. Some of these securities are supported
                     by the full faith and credit of the U.S. Treasury (e.g.,
                     Government National Mortgage Association securities),
                     others are supported by the right of the issuer to borrow
                     from the Treasury (e.g., Federal Farm Credit Bank
                     securities), while still others are supported only by the
                     credit of the instrumentality (e.g., Fannie Mae
                     securities).
VARIABLE AND FLOATING
RATE INSTRUMENTS
 
                     Certain of the obligations purchased by the Portfolio may
                     carry variable or floating rates of interest and may
                     involve a conditional or unconditional demand feature. Such
                     obligations may include variable amount master demand
                     notes. Such instruments bear interest at rates which are
                     not fixed, but which vary with changes in specified market
                     rates or indices. The interest rates on these securities
                     may be reset daily, weekly, quarterly or at some other
                     interval, and may have a floor or ceiling on interest rate
                     changes. There is a risk that the current interest rate on
                     such obligations may not accurately reflect existing market
                     interest rates. A demand instrument with a demand notice
                     period exceeding seven days may be considered illiquid if
                     there is no secondary market for such security.
WHEN-ISSUED AND DELAYED
DELIVERY SECURITIES
 
                     When-issued or delayed delivery transactions involve the
                     purchase of an instrument with payment and delivery taking
                     place in the future. Delivery of and payment for these
                     securities may occur a month or more after the date of the
                     purchase commitment. The Portfolio will maintain with the
                     custodian a separate account with liquid securities or cash
                     in an amount at least equal to these commitments. The
                     interest rate realized on these securities is fixed as of
                     the purchase date, and no interest accrues to the Portfolio
                     before settlement.
 
                                                                              15

This Prospectus sets forth concisely information about the above-referenced
Portfolio that an investor needs to know before investing. Please read this

with the Securities and Exchange Commission and is available upon request and
without charge by writing the Distributor, SEI Investments Distribution Co.,
Oaks, Pennsylvania 19456, or by calling 1-800-342-5734. The Statement of
Additional Information is incorporated into this Prospectus by reference.
 
SEI Tax Exempt Trust (the "Trust") is an open-end management investment company,
certain classes of which offer financial institutions a convenient means of
investing their own funds, or funds for which they act in a fiduciary, agency or
custodial capacity, in one or more professionally managed diversified and non-
diversified portfolios of securities. A portfolio may offer separate classes of
shares that differ from each other primarily in the allocation of certain
expenses and minimum investment amounts. This Prospectus offers Class B shares
of the Institutional Tax Free Portfolio (the "Portfolio"), a money market
portfolio.
 
AN INVESTMENT IN THE PORTFOLIO IS NEITHER INSURED NOR GUARANTEED BY THE U.S.
GOVERNMENT, AND THERE CAN BE NO ASSURANCE THAT THE PORTFOLIO WILL BE ABLE TO
MAINTAIN A STABLE NET ASSET VALUE OF $1.00 PER SHARE.
 
- --------------------------------------------------------------------------------
 
THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION, NOR HAS THE SECURITIES AND EXCHANGE COMMISSION PASSED UPON
THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY
IS A CRIMINAL OFFENSE.
 
  THE TRUST'S SHARES ARE NOT DEPOSITS OR OBLIGATIONS OF, OR GUARANTEED OR
  ENDORSED BY, ANY BANK. THE SHARES ARE NOT FEDERALLY INSURED BY THE FEDERAL
  DEPOSIT INSURANCE CORPORATION, THE FEDERAL RESERVE BOARD OR ANY OTHER

FINANCIAL HIGHLIGHTS
                  ______________________________________________________________
The following financial highlights for a share outstanding throughout each
period have been derived from the Trust's financial statements which were
audited by Arthur Andersen LLP, independent accountants, whose report thereon,
dated October 17, 1997, was unqualified. This information should be read in

INVESTMENT
OBJECTIVE AND
POLICIES
     ___________________________________________________________________________
 
                      The Portfolio's investment objective is to preserve
                      principal value and maintain a high degree of liquidity
                      while providing current income exempt from federal income
                      taxes. There can be no assurance that the Portfolio will
                      meet its investment objective.
                           The Portfolio invests in U.S. dollar denominated
                      municipal securities of issuers located in all fifty
                      states, the District of Columbia, Puerto Rico and other
                      U.S. territories and possessions (collectively, "Municipal
                      Securities"). It is a fundamental policy of the Portfolio
                      to invest at least 80% of its net assets in securities the
                      interest on which is exempt from federal income taxes,
                      based on opinions from bond counsel for the issuers, and
                      the Portfolio will invest, under normal conditions, at
                      least 80% of its net assets in securities the interest on
                      which is not a preference item for purposes of the federal
                      alternative minimum tax.
                           The Portfolio may purchase municipal bonds, municipal
                      notes and tax-exempt commercial paper, but only if such
                      securities, at the time of purchase, meet quality,
                      maturity and diversification requirements imposed by Rule
                      2a-7. See "General Investment Policies."
                           The Adviser will not invest more than 25% of
                      Portfolio assets in Municipal Securities (a) whose issuers
                      are located in the same state or (b) the interest on which
                      is derived from revenues of similar type projects. This
                      restriction does not apply to Municipal Securities in any
                      of the following categories: public housing authorities;
                      general obligations of states and localities; state and
                      local housing finance authorities or municipal utilities
                      systems.
                           There could be economic, business, or political
                      developments which might affect all Municipal Securities
                      of a similar type. To the extent that a significant
                      portion of the Portfolio's assets are invested in
                      Municipal Securities payable from revenues on similar
                      projects, the Portfolio will be subject to the peculiar
                      risks presented by such projects to a greater extent than
                      it would be if the Portfolio's
 
                                                                               4
<PAGE>
                      assets were not so invested. Moreover, in seeking to
                      attain its investment objective, the Portfolio may invest
                      all or any part of its assets in Municipal Securities that
                      are industrial development bonds.
 
GENERAL
INVESTMENT
POLICIES
     ___________________________________________________________________________
 
                      In purchasing obligations, the Portfolio complies with the
                      requirements of Rule 2a-7 under the Investment Company Act
                      of 1940 (the "1940 Act"), as that Rule may be amended from
                      time to time. These requirements currently provide that
                      the Portfolio must limit its investments to securities
                      with remaining maturities of 397 days or less, and must
                      maintain a dollar-weighted average maturity of 90 days or
                      less. In addition, the Portfolio may only invest in
                      eligible securities. In general, this means securities
                      rated in one of the two highest categories for short-term
                      securities by at least two nationally recognized
                      statistical rating organizations ("NRSROs") (or by one
                      NRSRO if only one NRSRO has rated the security), or, if
                      unrated, determined by Weiss, Peck & Greer, L.L.C. (the
                      "Adviser") to be of equivalent quality. Since the
                      Portfolio often purchases securities supported by credit
                      enhancements from banks and other financial institutions,
                      changes in the credit quality of these institutions could
                      cause losses to the Portfolio and affect its share price.
                           Securities rated in the highest rating category
                      (E.G., A-1 by Standard & Poor's Corporation ("S&P")) by at
                      least two NRSROs (or, if unrated, determined by the
                      Adviser to be of comparable quality) are "first tier"
                      securities. Non-first tier securities rated in the second
                      highest rating category (E.G., A-2 by S&P) by at least one
                      NRSRO (or, if unrated, determined by the Adviser to be of
                      comparable quality) are considered to be "second tier"
                      securities. The Portfolio's investments in non-first tier
                      conduit securities will be limited to 5% of the
                      Portfolio's assets. Conduit securities are securities
                      issued to finance non-governmental private projects, such
                      as housing developments and retirement homes, and for
                      which the ultimate obligor is not a governmental issuer.
                           The Portfolio may purchase securities on a
                      "when-issued" basis, variable and floating rate
                      obligations and reserves the right to engage in
                      transactions involving standby commitments. While the
                      Portfolio generally intends to be fully invested in
                      federally tax-exempt securities, the Portfolio may invest
                      up to 20% of its net assets in taxable money market
                      instruments (including repurchase agreements) and
                      securities the interest on which is a preference item for
                      purposes of the federal alternative minimum tax. The
                      Portfolio will not invest more than 10% of its total
                      assets in securities which are considered to be illiquid.
 
                                                                               5

INVESTMENT
LIMITATIONS
         _______________________________________________________________________
 
                      The investment objective and investment limitations are
                      fundamental policies of the Portfolio. Fundamental
                      policies cannot be changed with respect to the Trust or
                      the Portfolio without the consent of the holders of a
                      majority of the Trust's or the Portfolio's outstanding
                      shares. It is a fundamental policy of the Portfolio to use
                      its best efforts to maintain a constant net asset value of
                      $1.00 per share.
 
                      THE PORTFOLIO MAY NOT:
                      1. Purchase securities of any issuer (except securities
                         issued or guaranteed by the United States Government,
                         its agencies or instrumentalities) if, as a result,
                         more than 5% of the total assets of the Portfolio
                         (based on current market value at the time of
                         investment) would be invested in the securities of such
                         issuer; provided, however, that the Portfolio may
                         invest up to 25% of its total assets without regard to
                         this restriction of, and as permitted by, Rule 2a-7.
                      2. Purchase any securities which would cause more than 25%
                         of the total assets of the Portfolio, based on current
                         value at the time of such purchase, to be invested in
                         the securities of one or more issuers conducting their
                         principal business activities in the same industry,
                         provided that this limitation does not apply to
                         investments in obligations issued or guaranteed by the
                         U.S. Government or its agencies and instrumentalities.
                      3. Borrow money except for temporary or emergency
                         purposes, and then only in an amount not exceeding 10%
                         of the value of the total assets of the Portfolio. All
                         borrowings will be repaid before making additional
                         investments and any interest paid on such borrowings
                         will reduce the income of the Portfolio.
                      The foregoing percentage limitations will apply at the
                      time of the purchase of a security. Additional fundamental
                      investment limitations are set forth in the Statement of
                      Additional Information.

                      SEI Fund Management (the "Manager" and the "Transfer
                      Agent") provides the Trust with overall management
                      services, regulatory reporting, all necessary office
                      space, equipment, personnel and facilities, and serves as
                      institutional transfer agent and dividend disbursing
                      agent.
                           For these services, the Manager is entitled to a fee,
                      which is calculated daily and paid monthly, at an annual
                      rate of .36% of the average daily net assets of the
 
                                                                               6

                      Portfolio. The Manager has voluntarily agreed to waive a
                      portion of its fee in order to limit the total operating
                      expenses to not more than .63% of the average daily net
                      assets of the Class B shares of the Portfolio, on an
                      annualized basis. The Manager reserves the right, in its
                      sole discretion, to terminate this voluntary fee waiver at
                      any time. For the fiscal year ended August 31, 1997, the
                      Portfolio paid management fees, after waivers, of .25% of
                      its average daily net assets.
THE ADVISER
         _______________________________________________________________________
 
                      Weiss, Peck & Greer, L.L.C., serves as the Portfolio's
                      investment adviser under an investment advisory agreement
                      with the Trust (the "Advisory Agreement"). Under the
                      Advisory Agreement, the Adviser invests the assets of the
                      Portfolio, and continuously reviews, supervises and
                      administers the Portfolio's investment program. The
                      Adviser is independent of the Manager and discharges its
                      responsibilities subject to the supervision of, and
                      policies set by, the Trustees of the Trust.
                           The Adviser is a limited liability company founded as
                      a limited partnership in 1970, and engages in investment
                      management, venture capital management and management
                      buyouts. The Adviser has been active since its founding in
                      managing portfolios of tax exempt securities. As of
                      September 30, 1997, total assets under management were
                      approximately $14.6 billion. The principal business
                      address of the Adviser is One New York Plaza, New York,
                      New York 10004.
                           Janet Fiorenza acts as the portfolio manager for the
                      Portfolio. Ms. Fiorenza, a Principal of the Adviser, has
                      been associated with the Adviser's Tax Exempt Fixed Income
                      group since 1988, and with its predecessor since 1980.
                           For its services, the Adviser is entitled to a fee,
                      which is calculated daily and paid monthly, at an annual
                      rate of .05% of the combined average daily net assets of
                      the money market portfolios of the Trust that are advised
                      by the Adviser up to $500 million, .04% of such assets
                      from $500 million to $1 billion and .03% of such assets in
                      excess of $1 billion. Such fees are allocated daily among
                      these portfolios based on their relative net assets. For
                      the fiscal year ended August 31, 1997 the Portfolio paid
                      advisory fees, after waivers, of .04% of its relative net
                      assets.
 
DISTRIBUTION AND
SHAREHOLDER
SERVICING
      __________________________________________________________________________
 
                      SEI Investments Distribution Co. (the "Distributor"), a
                      wholly owned subsidiary of SEI Investments Company ("SEI
                      Investments"), serves as the Portfolio's distributor
                      pursuant to a distribution agreement (the "Distribution
                      Agreement") with the Trust.
                           The Portfolio has adopted plans under which firms,
                      including the Distributor, that provide shareholder and
                      administrative services may receive compensation
 
                                                                               7
<PAGE>
                      therefor. The Class A, B and C plans differ in a number of
                      ways, including the amounts that may be paid. Under each
                      plan, the Distributor may provide those services itself or
                      may enter into arrangements under which third parties
                      provide such services and are compensated by the
                      Distributor. Under such arrangements the Distributor may
                      retain as a profit any difference between the fee it
                      receives and the amount it pays such third parties. In
                      addition, the Portfolio may enter into such arrangements
                      directly.
                           Under the Class B shareholder service plan, the
                      Distributor is entitled to receive shareholder service
                      fees at an annual rate of up to .25% of average daily net
                      assets in return for the Distributor's (or its agent's)
                      efforts in maintaining client accounts; arranging for bank
                      wires; responding to client inquiries concerning services
                      provided or investment; and assisting clients in changing
                      dividend options, account designations and addresses. In
                      addition, under its administrative services plan, Class B
                      shares will pay administrative services fees to the
                      Distributor at specified percentages of the average daily
                      net assets of the shares of the Class (up to .05%).
                      Administrative services include sub-accounting; providing
                      information on share positions to clients; forwarding
                      shareholder communications to clients; processing
                      purchase, exchange and redemption orders and processing
                      dividend payments.
                           It is possible that an institution may offer
                      different classes of shares to its customers and differing
                      services to the Classes of the Portfolio and thus receive
                      compensation with respect to different classes. These
                      financial institutions may also charge separate fees to
                      their customers.
                           The Trust may execute brokerage or other agency
                      transactions through the Distributor for which the
                      Distributor may receive compensation.
                           The Distributor may, from time to time and at its own
                      expense provide promotional incentives, in the form of
                      cash or other compensation, to certain financial
                      institutions whose representatives have sold or are
                      expected to sell significant amounts of the Portfolio's
                      shares.
 
PURCHASE AND
REDEMPTION OF
SHARES
    ____________________________________________________________________________
 
                      Financial institutions may acquire shares of the Portfolio
                      for their own account, or as a record owner on behalf of
                      fiduciary, agency or custody accounts, by placing orders
                      with the Transfer Agent (or its authorized agent).
                      Institutions that use certain SEI proprietary systems may
                      place orders electronically through those systems.
                      Financial institutions which purchase shares for the
                      accounts of their customers may impose separate charges on
                      these customers for account services. Financial
                      institutions may impose an earlier cut-off time for
                      receipt of purchase
 
                                                                               8

                      orders directed through them to allow for processing and
                      transmittal of these orders to the Transfer Agent for
                      effectiveness on the same day.
                           Shares of the Portfolio may be purchased or redeemed
                      on days on which the New York Stock Exchange is open for
                      business ("Business Days"). However, money market fund
                      shares cannot be purchased by Federal Reserve wire on
                      federal holidays restricting wire transfers.
                           Shareholders who desire to purchase shares for cash
                      must place their orders with the Transfer Agent (or its
                      authorized agent) prior to the determination of net asset
                      value and in accordance with the procedures described
                      below for the order to be accepted on that Business Day.
                      Cash investments must be transmitted or delivered in
                      federal funds to the wire agent by the close of business
                      on the same day the order is placed.
                           The Trust reserves the right to reject a purchase
                      order when the Transfer Agent determines that it is not in
                      the best interest of the Trust or shareholders to accept
                      such purchase order.
                           The Trust will send shareholders a statement of
                      shares owned after each transaction. The purchase price of
                      shares is the net asset value next determined after a
                      purchase order is received and accepted by the Trust,
                      which is expected to remain constant at $1.00. The net
                      asset value per share of the Portfolio is determined by
                      dividing the total value of its investments and other
                      assets, less any liabilities, by the total number of
                      outstanding shares of the Portfolio. The Portfolio's
                      investments will be valued by the amortized cost method
                      described in the Statement of Additional Information. Net
                      asset value per share is determined daily as of 2:00 p.m.,
                      Eastern time, on each Business Day.
                           Shareholders who desire to redeem shares of the
                      Portfolio must place their redemption orders with the
                      Transfer Agent (or its authorized agent) prior to 12:30
                      p.m., Eastern time, on any Business Day. Otherwise, the
                      redemption order will be effective on the next Business
                      Day. The redemption price is the net asset value per share
                      of the Portfolio next determined after receipt by the
                      Transfer Agent, and effectiveness, of the redemption
                      order. For redemption orders received before 12:30 p.m.,
                      Eastern time, on any Business Day, payment will be made
                      the same day by transfer of federal funds. Otherwise, the
                      redemption will be effective on the next Business Day.
                           If a shareholder's aggregate balance is less than $45
                      million as a result of redemption or transfer, for a
                      period of seven consecutive days, the Trust reserves the
                      right to redeem that shareholder's shares in the Portfolio
                      for their current net asset value. Before the Trust
                      redeems such shares, the shareholder will be given notice
                      that the value of its shares is less than the minimum
                      amount and will be allowed sixty days to make an
                      additional investment in an amount that will increase the
                      value of the account to at least $50 million.
 
                                                                               9
<PAGE>
                           Purchase and redemption orders may be placed by
                      telephone. Neither the Trust nor the Transfer Agent will
                      be responsible for any loss, liability, cost or expense
                      for acting upon wire instructions or upon telephone
                      instructions that it reasonably believes to be genuine.
                      The Trust and the Transfer Agent will each employ
                      reasonable procedures to confirm that instructions
                      communicated by telephone are genuine, including requiring
                      a form of personal identification prior to acting upon
                      instructions received by telephone and recording telephone
                      instructions.
                           If market conditions are extraordinarily active, or
                      other extraordinary circumstances exist, shareholders may
                      experience difficulties placing redemption orders by
                      telephone, and may wish to consider placing orders by
                      other means.
PERFORMANCE_____________________________________________________________________
 
                      From time to time the Portfolio advertises its "current
                      yield," "tax equivalent yield" and "effective yield."
                      These figures are based on historical earnings and are not
                      intended to indicate future performance. The "current
                      yield" of the Portfolio refers to the income generated by
                      an investment over a seven-day period which is then
                      "annualized." That is, the amount of income generated by
                      the investment during the 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" (also
                      called "effective compound yield") is calculated similarly
                      but, when annualized, the income earned by an investment
                      is assumed to be reinvested. The "effective yield" will be
                      slightly higher than the "current yield" because of the
                      compounding effect of this assumed reinvestment. The "tax
                      equivalent yield" is calculated by determining the rate of
                      return that would have been achieved on a fully taxable
                      investment to produce the after-tax equivalent of the
                      Portfolio's yield, assuming certain tax brackets for a
                      shareholder.
                           The Portfolio may periodically compare its
                      performance to that of: (i) other mutual funds tracked by
                      mutual fund rating services (such as Lipper Analytical),
                      financial and business publications and periodicals; (ii)
                      broad groups of comparable mutual funds; (iii) unmanaged
                      indices which may assume investment of dividends but
                      generally do not reflect deductions for administrative and
                      management costs; or (iv) other investment alternatives.
                      The Portfolio may also quote financial and business
                      publications and periodicals as they relate to fund
                      management, investment philosophy and investment
                      techniques.
                           The performance of Class A shares will normally be
                      higher than that of Class B and Class C shares because of
                      the additional administrative services expenses charged to
                      Class B and Class C shares.
 
                                                                              10

TAXES
  ______________________________________________________________________________
 
                      The following summary of federal income tax consequences
                      is based on current tax laws and regulations, which may be
                      changed by legislative, judicial or administrative action.
                      No attempt has been made to present a detailed explanation
                      of the federal income tax treatment of the Portfolio or
                      its shareholders, and state and local tax consequences of
                      an investment in the Portfolio may differ from the federal
                      income tax consequences described below. Accordingly,
                      shareholders are urged to consult their tax advisers
                      regarding specific questions as to federal, state and
                      local income taxes. Additional information concerning
                      taxes is set forth in the Statement of Additional
                      Information.
TAX STATUS OF THE PORTFOLIO
                      The Portfolio is treated as a separate entity for federal
                      income tax purposes and is not combined with the Trust's
                      other portfolios. The Portfolio intends to continue to
                      qualify for the special tax treatment afforded regulated
                      investment companies under Subchapter M of the Internal
                      Revenue Code of 1986, as amended (the "Code"), so as to be
                      relieved of federal income tax on net investment company
                      taxable income and net capital gain (the excess of net
                      long-term capital gain over net short-term capital loss)
                      distributed to shareholders.
TAX STATUS OF DISTRIBUTIONS
                      The Portfolio intends to distribute substantially all of
                      its net investment income (including net short-term
                      capital gain) to shareholders. If, at the close of each
                      quarter of its taxable year, at least 50% of the value of
                      the Portfolio's total assets consists of obligations the
                      interest on which is excludable from gross income, the
                      Portfolio may pay "exempt-interest dividends" to its
                      shareholders. Exempt-interest dividends are excludable
                      from a shareholder's gross income for federal income tax
                      purposes but may have certain collateral federal tax
                      consequences including alternative minimum tax
                      consequences. In addition, the receipt of exempt-interest
                      dividends may cause persons receiving Social Security or
                      Railroad Retirement benefits to be taxable on a portion of
                      such benefits. See the Statement of Additional
                      Information.
                           Any dividends paid out of income realized by the
                      Portfolio on taxable securities will be taxable to
                      shareholders as ordinary income (whether received in cash
                      or in additional shares) to the extent of the Portfolio's
                      earnings and profits and will not qualify for the
                      dividends-received deduction for corporate shareholders.
                      Distributions to shareholders of net capital gains of the
                      Portfolio also will not qualify for the dividends received
                      deduction and will be taxable to shareholders as long-term
                      capital gain, whether received in cash or additional
                      shares, and regardless of how long a shareholder has held
                      the shares.
                           Dividends declared by the Portfolio in October,
                      November or December of any year and payable to
                      shareholders of record on a date in any such month will be
 
                                                                              11
<PAGE>
                      deemed to have been paid by the Portfolio and received by
                      the shareholders on December 31 of that year if paid by
                      the Portfolio at any time during the following January.
                      The Portfolio intends to make sufficient distributions
                      prior to the end of each calendar year to avoid liability
                      for the federal excise tax applicable to regulated
                      investment companies.
                           Interest on indebtedness incurred or continued by a
                      shareholder in order to purchase or carry shares of the
                      Portfolio is not deductible for federal income tax
                      purposes to the extent that it relates to exempt-interest
                      dividends distributed to the shareholder during the
                      taxable year. Furthermore, the Portfolio may not be an
                      appropriate investment for persons (including corporations
                      and other business entities) who are "substantial users"
                      (or persons related to "substantial users") of facilities
                      financed by industrial development bonds or private
                      activity bonds. Such persons should consult their tax
                      advisers before purchasing shares.
                           The Portfolio will report annually to its
                      shareholders the portion of dividends that is taxable and
                      the portion that is tax-exempt based on income received by
                      the Portfolio during the year to which the dividends
                      relate.
                           Each sale, exchange, or redemption of the Portfolio's
                      shares is a taxable transaction to the shareholder.
 
GENERAL
INFORMATION
         _______________________________________________________________________
THE TRUST
                      The Trust was organized as a Massachusetts business trust
                      under a Declaration of Trust dated March 15, 1982. The
                      Declaration of Trust permits the Trust to offer separate
                      portfolios of shares and different classes of each
                      portfolio. In addition to the Portfolio, the Trust
                      consists of the following portfolios: Tax Free Portfolio,
                      California Tax Exempt Portfolio, Intermediate-Term
                      Municipal Portfolio, Pennsylvania Municipal Portfolio, New
                      York Intermediate-Term Municipal Portfolio, and
                      Pennsylvania Tax Free Portfolio. All consideration
                      received by the Trust for shares of any portfolio and all
                      assets of such portfolio belong to that portfolio and
                      would be subject to liabilities related thereto.
                           The Trust pay its expenses, including fees of its
                      service providers, audit and legal expenses, expenses of
                      preparing prospectuses, proxy solicitation materials and
                      reports to shareholders, costs of custodial services and
                      registering the shares under federal and state securities
                      laws, pricing, insurance expenses, litigation and other
                      extraordinary expenses, brokerage costs, interest charges,
                      taxes and organization expenses.
TRUSTEES OF THE TRUST
                      The management and affairs of the Trust are supervised by
                      the Trustees under the laws of the Commonwealth of
                      Massachusetts. The Trustees have approved contracts
 
                                                                              12

                      under which, as described above, certain companies provide
                      essential services to the Trust.
VOTING RIGHTS
                      Each share held entitles the shareholder of record to one
                      vote. The shareholders of each portfolio or class will
                      vote separately on matters relating solely to that
                      Portfolio or class, such as any distribution plan. As a
                      Massachusetts business trust, the Trust is not required to
                      hold annual meetings of shareholders, but approval will be
                      sought for certain changes in the operation of the Trust
                      and for the election of Trustees under certain
                      circumstances. In addition, a Trustee may be removed by
                      the remaining Trustees or by shareholders at a special
                      meeting called upon written request of shareholders owning
                      at least 10% of the outstanding shares of the Trust. In
                      the event that such a meeting is requested, the Trust will
                      provide appropriate assistance and information to the
                      shareholders requesting the meeting.
REPORTING
                      The Trust issues unaudited financial statements
                      semi-annually and audited financial statements annually.
                      The Trust furnishes proxy statements and other reports to
                      shareholders of record.
SHAREHOLDER INQUIRIES
                      Shareholder inquiries should be directed to the Manager.
                      SEI Fund Management, Oaks, Pennsylvania, 19456.
DIVIDENDS
                      The net investment income (exclusive of capital gains) of
                      the Portfolio is determined and declared on each Business
                      Day as a dividend for shareholders of record as of the
                      close of business on that day. Dividends are paid by the
                      Portfolio in federal funds or in additional shares at the
                      discretion of the shareholder on the first Business Day of
                      each month. Dividends will be paid on the next Business
                      Day to shareholders who redeem all of their shares of the
                      Portfolio at any time during the month. Currently, capital
                      gains, if any, are distributed at the end of the calendar
                      year.
                           Shareholders automatically receive all income
                      dividends and capital gain distributions in additional
                      shares, unless the shareholder has elected to take such
                      payment in cash. Shareholders may change their election by
                      providing written notice to the Manager at least 15 days
                      prior to the distribution.
                           The dividends on Class A shares of the Portfolio are
                      normally higher than those on Class B and Class C shares
                      because of the additional administrative services expenses
                      charged to Class B and Class C shares.

DESCRIPTION
OF PERMITTED
INVESTMENTS
AND RISK FACTORS
               _________________________________________________________________
 
                      The following is a description of certain of the permitted
                      investments for the Portfolio, and the associated risk
                      factors:
MONEY MARKET SECURITIES
                      Money market securities are high-quality,
                      dollar-denominated, short-term debt instruments. They
                      consist of: (i) bankers' acceptances, certificates of
                      deposits, notes and time deposits of highly-rated U.S.
                      banks; (ii) U.S. Treasury obligations and obligations
                      issued by the agencies and instrumentalities of the U.S.
                      Government; and (iii) repurchase agreements involving any
                      of the foregoing obligations entered into with
                      highly-rated banks and broker-dealers.
MUNICIPAL SECURITIES
                      Municipal Securities consist of (i) debt obligations
                      issued by or on behalf of public authorities to obtain
                      funds to be used for various public facilities, for
                      refunding outstanding obligations, for general operating
                      expenses and for lending such funds to other public
                      institutions and facilities, and (ii) certain private
                      activity and industrial development bonds issued by or on
                      behalf of public authorities to obtain funds to provide
                      for the construction, equipment, repair or improvement of
                      privately operated facilities.
                           General obligation bonds are backed by the taxing
                      power of the issuing municipality. Revenue bonds are
                      backed by the revenues of a project or facility, tolls
                      from a toll bridge, for example. Certificates of
                      participation represent an interest in an underlying
                      obligation or commitment such as an obligation issued in
                      connection with a leasing arrangement. The payment of
                      principal and interest on private activity and industrial
                      development bonds generally is dependent solely on the
                      ability of the facility's user to meet its financial
                      obligations and the pledge, if any, of real and personal
                      property so financed as security for such payment.
                           Municipal notes include general obligation notes, tax
                      anticipation notes, revenue anticipation notes, bond
                      anticipation notes, certificates of indebtedness, demand
                      notes and construction loan notes and participation
                      interests in municipal notes. Municipal bonds include
                      general obligation bonds, revenue or special obligation
                      bonds, private activity and industrial development bonds
                      and participation interests in municipal bonds.
REPURCHASE AGREEMENTS
                      Repurchase agreements are arrangements by which a
                      Portfolio obtains a security and simultaneously commits to
                      return the security to the seller at an agreed upon price
                      (including principal and interest) on an agreed upon date
                      within a number of days from the date of purchase.
                      Repurchase agreements are considered loans under the 1940
                      Act.
 
                                                                              14
<PAGE>
STANDBY COMMITMENTS AND PUTS
                      Securities subject to standby commitments or puts permit
                      the holder thereof to sell the securities at a fixed price
                      prior to maturity. Securities subject to a standby
                      commitment or put may be sold at any time at the current
                      market price. However, unless the standby commitment or
                      put was an integral part of the security as originally
                      issued, it may not be marketable or assignable; therefore,
                      the standby commitment or put would only have value to the
                      Portfolio owning the security to which it relates. In
                      certain cases, a premium may be paid for a standby
                      commitment or put, which premium will have the effect of
                      reducing the yield otherwise payable on the underlying
                      security. The Portfolio will limit standby commitment or
                      put transactions to institutions believed to present
                      minimal credit risk.
U.S. GOVERNMENT OBLIGATIONS
                      Obligations issued by the U.S. Treasury or issued or
                      guaranteed by agencies of the U.S. Government and
                      obligations issued or guaranteed by instrumentalities of
                      the U.S. Government. Some of these securities are
                      supported by the full faith and credit of the U.S.
                      Treasury (E.G., Government National Mortgage Association
                      securities), others are supported by the right of the
                      issuer to borrow from the Treasury (E.G., Federal Farm
                      Credit Bank securities), while still others are supported
                      only by the credit of the instrumentality (E.G., Fannie
                      Mae securities).
VARIABLE AND FLOATING RATE INSTRUMENTS
                      Certain of the obligations purchased by the Portfolio may
                      carry variable or floating rates of interest and may
                      involve a conditional or unconditional demand feature.
                      Such obligations may include variable amount master demand
                      notes. Such instruments bear interest at rates which are
                      not fixed, but which vary with changes in specified market
                      rates or indices. The interest rates on these securities
                      may be reset daily, weekly, quarterly or at some other
                      interval, and may have a floor or ceiling on interest rate
                      changes. There is a risk that the current interest rate on
                      such obligations may not accurately reflect existing
                      market interest rates. A demand instrument with a demand
                      notice period exceeding seven days may be considered
                      illiquid if there is no secondary market for such
                      security.
WHEN-ISSUED AND DELAYED DELIVERY SECURITIES
                      When-issued or delayed delivery transactions involve the
                      purchase of an instrument with payment and delivery taking
                      place in the future. Delivery of and payment for these
                      securities may occur a month or more after the date of the
                      purchase commitment. The Portfolio will maintain with the
                      custodian a separate account with liquid securities or
                      cash in an amount at least equal to these commitments. The
                      interest rate realized on these securities is fixed as of
                      the purchase date, and no interest accrues to the
                      Portfolio before settlement.
 
                                                                              15

                                   THE TRUST
 
    SEI Tax Exempt Trust (the "Trust") is an open-end management investment
company established as a Massachusetts business trust pursuant to a Declaration
of Trust dated March 15, 1982. The Declaration of Trust permits the Trust to
offer separate series ("portfolios") of units of beneficial interest ("shares")
and separate classes of portfolios. This Statement of Additional Information
relates to the following portfolios: Tax Free, Institutional Tax Free,
California Tax Exempt, Intermediate-Term Municipal, Pennsylvania Municipal,
Pennsylvania Tax Free, and New York Intermediate-Term Municipal Portfolios (each
a "Portfolio," and collectively, the "Portfolios"), and any different classes of
the Portfolios. Except for differences between the Class A, Class B, Class C,
Class D and CNI Class shares of any Portfolio pertaining to sales loads,
shareholder servicing and administrative services plans, distribution plans,
transfer agency costs, voting rights and/or dividends, each share of each
Portfolio represents an equal proportionate interest in that Portfolio with each
other share of that Portfolio.
 
                      DESCRIPTION OF PERMITTED INVESTMENTS
 
    BANKERS' ACCEPTANCES--Bankers' acceptances are bills of exchange or time
drafts drawn on and accepted by a commercial bank. Bankers' acceptances are
issued by corporations to finance the shipment and storage of goods. Maturities
are generally six months or less.
 
    CERTIFICATES OF DEPOSIT--Certificates of deposit is an interest-bearing
instrument with a specific maturity. They are issued by banks and savings and
loan institutions in exchange for the deposit of funds and normally can be
traded in the secondary market prior to maturity. Certificates of deposit with
penalties for early withdrawal will be considered illiquid.
 
    COMMERCIAL PAPER--Commercial paper is a term used to describe unsecured
short-term promissory notes issued by banks, municipalities, corporations and
other entities. Maturities on these issues vary from one to 270 days.
 
    FIXED INCOME SECURITIES--Fixed income securities are debt obligations issued
by corporations, municipalities and other borrowers. The market value of a
Portfolio's fixed income investments will change in response to interest rate
changes and other factors. During periods of falling interest rates, the values
of outstanding fixed income securities generally rise. Conversely, during
periods of rising interest rates, the values of such securities generally
decline. Changes by recognized rating agencies in the rating of any fixed income
security and in the ability of an issuer to make payments of interest and
principal also affect the value of these investments. Changes in the value of
portfolio securities will not necessarily affect cash income derived from these
securities, but will affect a Portfolio's net asset value.
 
    INVESTMENT COMPANY SHARES--Each Portfolio may invest in shares of other
investment companies, to the extent permitted by applicable law and subject to
certain restrictions set forth in this Statement of Additional Information.
These investment companies typically incur fees that are separate from those
fees incurred directly by a Portfolio. A Portfolio's purchase of such investment
company securities results in the layering of expenses, such that shareholders
would indirectly bear a proportionate share of the operating expenses of such
investment companies, including advisory fees, in addition to paying Portfolio
expenses. Under applicable regulations, a Portfolio is prohibited from acquiring
the securities of another investment company if, as a result of such
acquisition: (1) the Portfolio owns more than 3% of the total voting stock of
the other company; (2) securities issued by any one investment company represent
more than 5% of the Portfolio's total assets; or (3) securities (other than
treasury stock) issued by all investment companies represent more than 10% of
the total assets of the Portfolio.
 
    MUNICIPAL LEASES--Each Portfolio may invest in instruments, or
participations in instruments, issued in connection with lease obligations or
installment purchase contract obligations of municipalities ("municipal lease
obligations"). Although municipal lease obligations do not constitute general
obligations of the issuing municipality, a lease obligation is ordinarily backed
by the municipality's covenant to budget
 
                                      S-2
<PAGE>
for, appropriate funds for, and make the payments due under the lease
obligation. However, certain lease obligations contain "non-appropriation"
clauses, which provide that the municipality has no obligation to make lease or
installment purchase payments in future years unless money is appropriated for
such purpose in the relevant years. Municipal lease obligations are a relatively
new form of financing, and the market for such obligations is still developing.
Municipal leases will be treated as liquid only if they satisfy criteria set
forth in guidelines established by the Board of Trustees, and there can be no
assurance that a market will exist or continue to exist for any municipal lease
obligation.
 
    MUNICIPAL NOTES--Municipal notes consist of general obligation notes, tax
anticipation notes (notes sold to finance working capital needs of the issuer in
anticipation of receiving taxes on a future date), revenue anticipation notes
(notes sold to provide needed cash prior receipt of expected non-tax revenues
from a specific source), bond anticipation notes, tax and revenue anticipation
notes, certificates of indebtedness, demand notes, and construction loan notes.
The maturities of the instruments at the time of issue will generally range from
three months to one year.
 
    MUNICIPAL BONDS--Municipal bonds are debt obligations issued to obtain funds
for various public purposes. A Portfolio may purchase private activity or
industrial development bonds if the interest paid is exempt from federal income
tax. These bonds are issued by or on behalf of public authorities to raise money
to finance various privately-owned or -operated facilities for business and
manufacturing, housing, sports, and pollution control. These bonds are also used
to finance public facilities such as airports, mass transit systems, ports,
parking or sewage or solid waste disposal facilities, as well as certain other
categories. The payment of the principal and interest on such bonds is dependent
solely on the ability of the facility's user to meet its financial obligations
and the pledge, if any, of real and personal property so financed as security
for such payment.
 
    REPURCHASE AGREEMENTS--Repurchase agreements are agreements under which
securities are acquired from a securities dealer or bank subject to resale on an
agreed upon date and at an agreed upon price which includes principal and
interest. Each Portfolio or its agent will have actual or constructive
possession of the securities held as collateral for the repurchase agreement.
Each Portfolio bears a risk of loss in the event the other party defaults on its
obligations and the Portfolio is delayed or prevented from exercising its right
to dispose of the collateral securities, or if the Portfolio realizes a loss on
the sale of the collateral securities. The Advisers or Sub-Adviser will enter
into repurchase agreements on behalf of a Portfolio only with financial
institutions deemed to present minimal risk of bankruptcy during the term of the
agreement based on guidelines established and periodically reviewed by the Board
of Trustees. These guidelines currently permit the Portfolios to enter into
repurchase agreements only with approved banks and primary securities dealers,
as recognized by the Federal Reserve Bank of New York, which have minimum net
capital of $100 million, or with a member bank of the Federal Reserve System.
Repurchase agreements are considered to be loans collateralized by the
underlying security. Repurchase agreements entered into by the Portfolios will
provide that the underlying security at all times shall have a value at least
equal to 102% of the price stated in the agreement. This underlying security
will be marked to market daily. The Advisers or Sub-Adviser will monitor
compliance with this requirement. Under all repurchase agreements entered into
by the Portfolios, the Custodian or its agent must take possession of the
underlying collateral. However, if the seller defaults, the Portfolios could
realize a loss on the sale of the underlying security to the extent the proceeds
of the sale are less than the resale price. In addition, even though the
Bankruptcy Code provides protection for most repurchase agreements, if the
seller should be involved in bankruptcy or insolvency proceedings, the
Portfolios may incur delays and costs in selling the security and may suffer a
loss of principal and interest if the Portfolios are treated as unsecured
creditors.
 
    STANDBY COMMITMENTS AND PUT TRANSACTIONS--The Portfolios reserve the right
to engage in put transactions. The Advisers and Sub-Adviser have the authority
to purchase securities at a price which would result in a yield to maturity
lower than that generally offered by the seller at the time of purchase when the
Portfolios can simultaneously acquire the right to sell the securities back to
the seller,
 
                                      S-3
<PAGE>
the issuer, or a third party (the "writer") at an agreed-upon price at any time
during a stated period or on a certain date. Such a right is generally denoted
as a "standby commitment" or a "put." The purpose of engaging in transactions
involving puts is to maintain flexibility and liquidity to permit the Portfolios
to meet redemptions and remain as fully invested as possible in municipal
securities. The right to put the securities depends on the writer's ability to
pay for the securities at the time the put is exercised. The Portfolios would
limit their put transactions to institutions which the Adviser or Sub-Adviser
believes present minimum credit risks, and the Adviser or Sub-Adviser would use
its best efforts to initially determine and continue to monitor the financial
strength of the sellers of the options by evaluating their financial statements
and such other information as is available in the marketplace. It may, however,
be difficult to monitor the financial strength of the writers because adequate
current financial information may not be available. In the event that any writer
is unable to honor a put for financial reasons, a Portfolio would be a general
creditor (I.E., on a parity with all other unsecured creditors) of the writer.
Furthermore, particular provisions of the contract between a Portfolio and the
writer may excuse the writer from repurchasing the securities; for example, a
change in the published rating of the underlying securities or any similar event
that has an adverse effect on the issuer's credit or a provision in the contract
that the put will not be exercised except in certain special cases, for example,
to maintain portfolio liquidity. A Portfolio could, however, at any time sell
the underlying portfolio security in the open market or wait until the portfolio
security matures, at which time it should realize the full par value of the
security.
 
    The securities purchased subject to a put, may be sold to third persons at
any time, even though the put is outstanding, but the put itself, unless it is
an integral part of the security as originally issued, may not be marketable or
otherwise assignable. Therefore, the put would have value only to the Portfolio.
Sale of the securities to third parties or lapse of time with the put
unexercised may terminate the right to put the securities. Prior to the
expiration of any put option, a Portfolio could seek to negotiate terms for the
extension of such an option. If such a renewal cannot be negotiated on terms
satisfactory to the Portfolio, the Portfolio could, of course, sell the
security. The maturity of the underlying security will generally be different
from that of the put. The Intermediate-Term Municipal and Pennsylvania Municipal
Portfolios will consider the "maturity" of a security subject to a put to be the
first date on which it has the right to demand payment from the writer of the
put although the final maturity of the security is later than such date.
 
    The Trust has received a private letter ruling from the Internal Revenue
Service that, to the extent it purchases securities subject to the right to put
them back to the seller in order to maintain liquidity to meet redemption
requirements, it will be treated as the owner of those securities for federal
income tax purposes. No assurance can be given that legislative, judicial or
administrative changes may not be forthcoming which could modify the Trust's
private letter ruling.
 
    TIME DEPOSITS--Time deposits are non-negotiable receipts issued by a bank in
exchange for the deposit of funds. Like a certificate of deposit, it earns a
specified rate of interest over a definite period of time; however, it cannot be
traded in the secondary market. Time deposits with a withdrawal penalty are
considered to be illiquid securities.
 
    WHEN-ISSUED SECURITIES--These securities involve the purchase of debt
obligations on a when-issued basis, in which case delivery and payment normally
take place within 45 days after the date of commitment to purchase. These
securities are subject to market fluctuation due to changes in market interest
rates, and it is possible that the market value at the time of settlement could
be higher or lower than the purchase price if the general level of interest
rates has changed. Although a Portfolio generally purchases securities on a
when-issued or forward commitment basis with the intention of actually acquiring
securities for its portfolio, a Portfolio may dispose of a when-issued security
or forward commitment prior to settlement if the Adviser deems it appropriate to
do so.
 
    The Portfolios will only make commitments to purchase obligations on a
when-issued basis with the intention of actually acquiring the securities, but
may sell them before the settlement date. The when-
 
                                      S-4
<PAGE>
issued securities are subject to market fluctuation, and no interest accrues to
the purchaser during this period. The payment obligation and the interest rate
that will be received on the securities are each fixed at the time the purchaser
enters into the commitment. Purchasing obligations on a when-issued basis is a
form of leveraging and can involve a risk that the yields available in the
market when the delivery takes place may actually be higher than those obtained
in the transaction itself. In that case there could be an unrealized loss at the
time of delivery.
 
    The Portfolios will establish segregated accounts with the Custodian and
will maintain liquid assets in an amount at least equal in value to the
Portfolios' commitments to purchase when-issued securities.
 
                             DESCRIPTION OF RATINGS
 
    MUNICIPAL NOTE RATINGS.  A Standard & Poor's Corporation ("S&P") note rating
reflects the liquidity concerns and market access risks unique to notes. Notes
due in 3 years or less will likely receive a note rating. Notes maturing beyond
3 years will most likely receive a long-term debt rating. The following criteria
will be used in making that assessment:
 
    - Amortization schedule (the larger the final maturity relative to other
      maturities the more likely it will be treated as a note).
 
    - Source of Payment (the more dependent the issue is on the market for its
      refinancing, the more likely it will be treated as a note).
 
    Note rating symbols are as follows:
 
    SP-1  Very strong or strong capacity to pay principal and interest. Those
issues determined to possess overwhelming safety characteristics will be given a
plus (+) designation.
 
    SP-2  Satisfactory capacity to pay principal and interest.
 
    Moody's Investors Service, Inc. ("Moody's") highest rating for state and
municipal and other short-term notes is MIG-1 and VMIG-1. Short-term municipal
securities rated MIG-1 or VMIG-1 are of the best quality. They have strong
protection from established cash flows of funds for their servicing or from
established and broad-based access to the market for refinancing or both.
Municipal obligations rated MIG-2 and VMIG-2 are high quality. Margins of
protection are ample although not so large as in the preceding group.
 
    MUNICIPAL AND CORPORATE BOND RATINGS.  Bonds rated AAA have the highest
rating S&P assigns to a debt obligation. Such a rating indicates an extremely
strong capacity to pay principal and interest. Bonds rated AA also qualify as
high-quality debt obligations. Capacity to pay principal and interest is very
strong, and in the majority of instances they differ from AAA issues only in
small degrees.
 
    Bonds rated A by S&P have a strong capacity to pay interest and repay
principal although it is somewhat more susceptible to the adverse effects of
changes in circumstances and economic conditions than debt in higher rated
categories. Debt rated BBB is regarded as having an adequate capacity to pay
interest and repay principal. Whereas it normally exhibits adequate protection
parameters, adverse economic conditions or changing circumstances are more
likely to lead to a weakened capacity to pay interest and repay principal for
debt in this category than in higher rated categories.
 
    Bonds which are rated Aaa by Moody's are judged to be of the best quality.
They carry the smallest degree of investment risk and are generally referred to
as "gilt edge." Interest payments are protected by a large, or an exceptionally
stable, margin and principal is secure. While the various protective elements
are likely to change, such changes as can be visualized are most unlikely to
impair the fundamentally strong position of such issues. Bonds rated Aa by
Moody's are judged by Moody's to be of high quality by all standards. Together
with bonds rated Aaa, they comprise what are generally known as high-grade
bonds.
 
                                      S-5
<PAGE>
They are rated lower than the best bonds because margins or protection may not
be as large as in Aaa-rated securities or fluctuation of protective elements may
be of greater amplitude or there may be other elements present which make the
long-term risks appear somewhat larger than in Aaa-rated securities.
 
    Bonds which are rated A by Moody's possess many favorable investment
attributes and are to be considered as upper-medium grade obligations. Factors
giving security to principal and interest are considered adequate, but elements
may be present which suggest a susceptibility to impairment sometime in the
future.
 
    Bonds which are rated Baa by Moody's are considered as medium-grade
obligations (I.E., they are neither highly protected nor poorly secured).
Interest payments and principal security appear adequate for the present but
certain protective elements may be lacking or may be characteristically
unreliable over any great length of time. Such bonds lack outstanding investment
characteristics and in fact have speculative characteristics as well.
 
    COMMERCIAL PAPER RATINGS.  Commercial paper rated A by S&P is regarded by
S&P as having the greatest capacity for timely payment. Issues rated A are
further refined by use of the numbers 1+, 1, 2 and 3 to indicate the relative
degree of safety, issues rated A-1+ are those with an "overwhelming degree" of
credit protection. Those rated A-1 reflect a "very strong" degree of safety
regarding timely payment. Those rated A-2 reflect a "satisfactory" degree of
safety regarding timely payment.
 
    Commercial paper issuers rated Prime-1 or Prime-2 by Moody's are judged by
Moody's to be of "superior" quality and "strong" quality, respectively, on the
basis of relative repayment capacity.
 
                             INVESTMENT LIMITATIONS
 
No Portfolio may:
 
1.  Borrow money except for temporary or emergency purposes and then only in an
    amount not exceeding 10% of the value of total assets. The California Tax
    Exempt Portfolio has a fundamental policy that to the extent such borrowing
    exceeds 5% of the value of the Portfolio's total assets, borrowing will be
    done from a bank and in accordance with the requirements of the 1940 Act.
    This borrowing provision is included solely to facilitate the orderly sale
    of portfolio securities to accommodate heavy redemption requests if they
    should occur and is not for investment purposes. All borrowings of the
    Portfolios, in excess of 5% of its total assets, will be repaid before
    making additional investments and any interest paid on such borrowings will
    reduce income.
 
2.  Purchase securities of other investment companies, except that the
    Intermediate-Term Municipal, Pennsylvania Municipal and Pennsylvania Tax
    Free Portfolios may only purchase securities of money market funds and the
    New York Intermediate-Term Municipal Portfolio may purchase securities of
    other investment companies, in either case, as permitted by the 1940 Act and
    the rules and regulations thereunder.
 
3.  Make loans, except that each Portfolio may purchase or hold debt instruments
    in accordance with its investment objective and policies and may enter into
    repurchase agreements, provided that repurchase agreements maturing in more
    than seven days, restricted securities and other illiquid securities are not
    to exceed, in the aggregate, 10% of the Portfolio's net assets, except for
    the Intermediate-Term Municipal and New York Intermediate-Term Municipal
    Portfolios, for which it cannot exceed 15% of the Portfolio's net assets.
 
4.  Pledge, mortgage or hypothecate assets except to secure temporary borrowings
    permitted by (1) above in aggregate amounts not to exceed 10% of the net
    assets of such Portfolio taken at current value at the time of the
    incurrence of such loan.
 
5.  Invest in companies for the purpose of exercising control.
 
                                      S-6
<PAGE>
 6. Acquire more than 10% of the voting securities of any one issuer.
 
 7. Purchase or sell real estate, real estate limited partnership interests,
    commodities or commodities contracts including futures contracts. However,
    subject to its permitted investments, any Portfolio may invest in municipal
    securities or other obligations secured by real estate or other interests
    therein.
 
 8. Make short sales of securities, maintain a short position or purchase
    securities on margin, except that the Portfolio may obtain short-term
    credits as necessary for the clearance of security transactions.
 
 9. Act as an underwriter of securities of other issuers except as it may be
    deemed an underwriter in selling a portfolio security.
 
10. Issue senior securities (as defined in the 1940 Act) except in connection
    with permitted borrowings as described in the Prospectuses and this
    Statement of Additional Information or as permitted by rule, regulation or
    order of the SEC.
 
11. Purchase or retain securities of an issuer if, to the knowledge of the
    Trust, an officer, trustee, partner or director of the Trust or any
    investment adviser of the Trust owns beneficially more than 1/2 of 1% of the
    shares or securities of such issuer and all such officers, trustees,
    partners and directors owning more than 1/2 of 1% of such shares or
    securities together own more than 5% of such shares or securities.
 
12. Purchase securities of any company which has (with predecessors) a record of
    less than three years continuing operations (except (i) obligations issued
    or guaranteed by the United States Government, its agencies or
    instrumentalities, or (ii) municipal securities which are rated by at least
    two nationally recognized municipal bond rating services or determined by
    the Adviser or Sub-Adviser to be of "high quality") if, as a result, more
    than 5% of the total assets (taken at current value) would be invested in
    such securities.
 
13. Purchase warrants, calls, straddles, spreads or combinations thereof, except
    as permitted by its Prospectus and this Statement of Additional Information.
 
14. Invest in interests in oil, gas or other mineral exploration or development
    programs. The Institutional Tax Free Portfolio and the California Tax Exempt
    Portfolio may not invest in oil, gas or mineral leases.
 
15. Invest more than 25% of total assets in issues within the same state or
    similar type projects (except in specified categories). This investment
    limitation applies to the Intermediate-Term Municipal Portfolio, Tax Free
    Portfolio, Institutional Tax Free Portfolio, and Pennsylvania Municipal
    Portfolio. For the Pennsylvania Municipal Portfolio, this limitation does
    not apply to the extent stated in its investment objective and policies.
 
    The foregoing percentages (except the limitation on borrowing) will apply at
the time of the purchase of a security. These investment limitations and the
investment limitations in each Prospectus are fundamental policies of the Trust
and may not be changed without shareholder approval, except that for the New
York Intermediate-Term Municipal Portfolio investment limitations 2, 4, 8, 11,
12, 13 and 14 are not fundamental and do not require shareholder approval to be
amended. It is a fundamental policy of the Intermediate-Term Municipal and
Pennsylvania Municipal Portfolios to abide by the maturity restrictions and to
invest solely in the permitted investments described in this Statement of
Additional Information and in their respective Prospectuses.

                           STATE SPECIFIC DISCLOSURE
 
    The following information constitutes only a brief summary, and is not
intended as a complete description.
 
SPECIAL CONSIDERATIONS RELATING TO CALIFORNIA MUNICIPAL SECURITIES
 
    The ability of issuers to pay interest on, and repay principal of,
California municipal securities ("California Municipal Securities") may be
affected by (1) amendments to the California Constitution and related statutes
that limit the taxing and spending authority of California government entities,
and related civil actions, (2) a wide variety of California laws and
regulations, and (3) the general financial condition of the State of California.
 
    ADDITIONAL CONSIDERATIONS.  With respect to Municipal Securities issued by
the State of California and its political subdivisions, as well as certain other
governmental issuers such as the Commonwealth of Puerto Rico, the Trust cannot
predict what legislation, if any, may be proposed in the California State
Legislature as regards the California State personal income tax status of
interest on such obligations, or which proposals, if any, might be enacted. Such
proposals, if enacted, might materially adversely affect the availability of
California Municipal Securities for investment by the Portfolios and the value
of the Portfolios' investments.
 
SPECIAL CONSIDERATIONS RELATING TO NEW YORK MUNICIPAL SECURITIES
 
    REVENUES AND EXPENDITURES.  New York's Governmental Funds receive a majority
of their revenues from taxes levied by the State. Investment income, fees and
assessments, abandoned property collections, and other varied sources supply the
balance of the receipts for these Funds. New York's major expenditures are
grants to local governments.
 
    NEW YORK CITY.  The fiscal health of the State is closely related to the
fiscal health of its localities, particularly the City, which has required
significant financial assistance from the State in recent years.
 
SPECIAL CONSIDERATIONS RELATING TO PENNSYLVANIA MUNICIPAL SECURITIES
 
    REVENUES AND EXPENDITURES.  The Constitution of Pennsylvania provides that
operating budget appropriations may not exceed the estimated revenues and
available surplus in the fiscal year for which funds are appropriated. Annual
budgets are enacted for the General Fund and for certain special revenue funds
which represent the majority of expenditures of the Commonwealth. Pennsylvania's
Governmental Funds receive a majority of their revenues from taxes levied by the
Commonwealth. Interest earnings, licenses and fees, lottery ticket sales, liquor
store profits, miscellaneous revenues, augmentations and federal government
grants supply the balance of the receipts of these funds.
 
    LOCAL GOVERNMENT DEBT.  Local government in Pennsylvania consists of
numerous individual units. Each unit is distinct and independent of other local
units, although they may overlap geographically. There is extensive general
legislation applying to local government. Municipalities may also issue revenue
obligations without limit and without affecting their general obligation
borrowing capacity if the obligations are projected to be paid solely from
project revenues. Municipal authorities and industrial development authorities
are also widespread in Pennsylvania.

    The Trust and SEI Fund Management ("SEI Management" or the "Manager") have
entered into a Management Agreement (the "Management Agreement"). The Management
Agreement provides that the Manager shall not be liable for any error of
judgement or mistake of law or for any loss suffered by the Trust in connection
with the matters to which the Management Agreement relates, except a loss
resulting from willful misfeasance, bad faith or gross negligence on the part of
the Manager in the performance of its duties or from reckless disregard of its
duties and obligations thereunder.
 
    The continuance of the Management Agreement must be specifically approved at
least annually (i) by the vote of a majority of the Trustees or by the vote of a
majority of the outstanding voting securities of the Portfolio, and (ii) by the
vote of a majority of the Trustees of the Trust who are not parties to the
Management Agreement or an "interested person" (as that term is defined in the
1940 Act) of any party thereto, cast in person at a meeting called for the
purpose of voting on such approval. The Management Agreement is terminable at
any time as to any Portfolio without penalty by the Trustees of the Trust, by a
vote of a majority of the outstanding shares of the Portfolio or by the Manager
on not less than 30 days' nor more than 60 days' written notice.

                     DISTRIBUTION AND SHAREHOLDER SERVICING
 
    The Trust has adopted Distribution Plans for Class D and CNI Class shares of
the Portfolios (the "Plans") in accordance with the provisions of Rule 12b-1
under the 1940 Act, which regulates circumstances under which an investment
company may directly or indirectly bear expenses relating to the distribution of
its shares. In this regard, the Board of Trustees has determined that the Plans
and the Distribution Agreement are in the best interests of the shareholders.
Continuance of the Plans must be approved annually by a majority of the Trustees
of the Trust and by a majority of the trustees who are not "interested persons"
of the Trust as that term is defined in the 1940 Act and who have no direct or
indirect financial interest in the operation of a Distribution Plan or in any
agreements related thereto ("Qualified Trustees"). The Plans require that
quarterly written reports of amounts spent under the Plans and the purposes of
such expenditures be furnished to and reviewed by the Trustees. The Plans may
not be amended to increase materially the amount which may be spent thereunder
without approval by a majority of the outstanding shares of the Portfolio or
class affected. All material amendments of the Plans will require approval by a
majority of the Trustees of the Trust and of the Qualified Trustees.
 
                                      S-10
<PAGE>
    The Plans provide that the Trust will pay the Distributor a fee on the Class
D and CNI Class shares of the Portfolio. The Distributor may use this fee for:
(i) compensation for its services in connection with distribution assistance or
provision of shareholder services or (ii) payments to financial institutions and
intermediaries such as banks, savings and loan associations, insurance companies
and investment counselors, broker-dealers and the Distributor's affiliates and
subsidiaries as compensation for services or reimbursement of expenses incurred
in connection with distribution assistance or provision of shareholder services.
 
    The Portfolios have also adopted shareholder servicing plans for its Class
A, Class B, Class C and CNI Class shares (the "Service Plans"), and
Administrative Services Plans for its Class B and Class C shares. Under these
Service and Administrative Services Plans, the Distributor may perform, or may
compensate other service providers for performing, the following shareholder and
administrative services: maintaining client accounts; arranging for bank wires;
responding to client inquiries concerning services provided on investments;
assisting clients in changing dividend options, account designations and
addresses; sub-accounting; providing information on share positions to clients;
forwarding shareholder communications to clients; processing purchase, exchange
and redemption orders; and processing dividend payments. Under the Service and
Administrative Services Plans, the Distributor may retain as a profit any
difference between the fee it receives and the amount it pays to third parties.
 
    For the fiscal year ended August 31, 1997, the Portfolios paid the following
amounts pursuant to the Distribution Plans:

                                  PERFORMANCE
 
    From time to time, the Portfolios may advertise yield and/or total return.
These figures will be based on historical earnings and are not intended to
indicate future performance.
 
    The current yield of the Portfolios that are money market funds is
calculated daily based upon the 7 days ending on the date of calculation ("base
period"). The yield is computed by determining the net change (exclusive of
capital changes) in the value of a hypothetical pre-existing shareholder account
having a balance of one share at the beginning of the period, subtracting a
hypothetical charge reflecting deductions from shareholder accounts and dividing
such net change by the value of the account at the beginning of the same period
to obtain the base period return and multiplying the result by (365/7). Realized
and unrealized gains and losses are not included in the calculation of the
yield.
 
    The Portfolios compute their effective compound yield by determining the net
changes, exclusive of capital changes, in the value of a hypothetical
pre-existing account having a balance of one share at the beginning of the
period, subtracting a hypothetical charge reflecting deductions from shareholder
accounts, and dividing the difference by the value of the account at the
beginning of the base period to obtain the base period return, and then
compounding the base period return by adding 1, raising the sum to a power equal
to 365 divided by 7, and subtracting 1 from the result, according to the
following formula: Effective Yield = {(Base Period Return + 1)(365/7)} - 1. The
current and the effective yields reflect the reinvestment of net income earned
daily on portfolio assets.
 
    From time to time, the Intermediate-Term Municipal, Pennsylvania Municipal,
and New York Intermediate-Term Portfolios may advertise yield. These figures
will be based on historical earnings and are not intended to indicate future
performance. The yield of these Portfolios refers to the annualized income
generated by an investment in the Portfolios over a specified 30-day period. The
yield is calculated by assuming that the income generated by the investment
during that period generated each period over one year and is shown as a
percentage of the investment. In particular, yield will be calculated according
to the following formula:
 
    Yield = 2([(a-b)/(cd) + 1)](6) - 1) where a = dividends and interest earned
during the period; b = expenses accrued for the period (net of reimbursement); c
= the current daily number of shares outstanding during the period that were
entitled to receive dividends; and d = the maximum offering price per share on
the last day of the period.
 
                                      S-14
<PAGE>
    Actual yields will depend on such variables as asset quality, average asset
maturity, the type of instruments a Portfolio invests in, changes in interest
rates on money market instruments, changes in the expenses of the Portfolios and
other factors.
 
    Yields are one basis upon which investors may compare the Portfolios with
other money market funds; however, yields of other money market mutual funds and
other investment vehicles may not be comparable because of the factors set forth
above and differences in the methods used in valuing portfolio instruments.
 
    For the 7-day period ended August 31, 1997, the end of the Trust's most
recent fiscal year, the money market Portfolios' current effective and
tax-equivalent yields were as follows:

    From time to time, the Intermediate-Term Municipal, Pennsylvania Municipal
and New York Intermediate-Term Municipal Portfolios may advertise total return.
The total return of a Portfolio refers to the average compounded rate of return
to a hypothetical investment for designated time periods (including, but not
limited to, the period from which the Portfolio commenced operations through the
specified date), assuming that the entire investment is redeemed at the end of
each period. In particular, total return will be calculated according to the
following formula: P(1 + T)n = ERV, where P = a hypothetical initial payment of
$1,000; T = average annual total return; n = number of years; and ERV = ending
redeemable value of a hypothetical $1,000 payment made at the beginning of the
designated time period as of the end of such period.

    Each Portfolio may, from time to time, compare its performance to other
mutual funds tracked by mutual fund rating services, to broad groups of
comparable mutual funds or to unmanaged indices which may assume investment of
dividends but generally do not reflect deductions for sales charges,
administrative and management costs.
 
                        DETERMINATION OF NET ASSET VALUE
 
    Securities of the Tax Free, Institutional Tax Free, California Tax Exempt
and the Pennsylvania Tax Free Portfolios will be valued by the amortized cost
method which involves valuing a security at its cost on the date of purchase and
thereafter (absent unusual circumstances) assuming a constant amortization to
maturity of any discount or premium, regardless of the impact of fluctuations in
general market rates of interest on the value of the instrument. While this
method provides certainty in valuation, it may result in periods during which
value, as determined by this method is higher or lower than the price the Trust
would receive if it sold the instrument. During periods of declining interest
rates, the daily yield of a Portfolio may tend to be higher than a like
computation made by a company with identical investments utilizing a method of
valuation based upon market prices and estimates of market prices for all of its
portfolio securities. Thus, if the use of amortized cost by a Portfolio resulted
in a lower aggregate portfolio value on a particular day, a prospective investor
in a Portfolio would be able to obtain a somewhat higher yield than would result
from investment in a company utilizing solely market values, and existing
shareholders in the Portfolio would experience a lower yield. The converse would
apply in a period of rising interest rates.
 
    A Portfolio's use of amortized cost valuation and the maintenance of the
Portfolio's net asset value at $1.00 are permitted by Rule 2a-7 under the 1940
Act, provided that certain conditions are met. Under Rule 2a-7 a money market
portfolio must maintain a dollar-weighted average maturity of 90 days or less,
and not purchase any instrument having a remaining maturity of more than 397
days. In addition, money market funds may acquire only U.S. dollar denominated
obligations that present minimal credit risks and
 
                                      S-16
<PAGE>
that are "eligible securities," which means they are: (i) rated, at the time of
investment, by at least two nationally recognized statistical rating
organizations (one if it is the only organization rating such obligation) in the
highest short-term rating category or, if unrated, determined to be of
comparable quality (a "first tier security"), or (ii) rated according to the
foregoing criteria in the second highest short-term rating category or, if
unrated, determined to be of comparable quality ("second tier security"). The
Advisers will determine that an obligation presents minimal credit risk or that
unrated instruments are of comparable quality in accordance with guidelines
established by the Trustees. In the event a first tier security of the Tax Free
Portfolio, Institutional Tax Free Portfolio, California Tax Exempt Portfolio or
the Pennsylvania Tax Free Portfolio is downgraded below first tier security
status after purchase, or the Adviser of the of any such Portfolio becomes aware
that an unrated or second tier security has received any rating below the second
highest rating category after purchase, the Portfolio's Adviser will either
dispose of the security within five business days or the Board of Trustees will
reassess whether the security continues to present minimal credit risks. The
Board may also delegate this responsibility to the Portfolio's Adviser with
respect to the downgrade of a first tier security. The regulations also require
the Trustees to establish procedures which are reasonably designed to stabilize
the net asset value per unit at $1.00 for each Portfolio. However, there is no
assurance that the Trust will be able to meet this objective. The Trust's
procedures include the determination of the extent of deviation, if any, of each
Portfolio's current net asset value per unit calculated using available market
quotations from each Portfolio's amortized cost price per unit at such intervals
as the Trustees deem appropriate and reasonable in light of market conditions
and periodic reviews of the amount of the deviation and the methods used to
calculate such deviation. In the event that such deviation exceeds 1/2 of 1%,
the Trustees are required to consider promptly what action, if any, should be
initiated; and, if the Trustees believe that the extent of any deviation may
result in material dilution or other unfair results to shareholders, the
Trustees are required to take such corrective action as they deem appropriate to
eliminate or reduce such dilution or unfair results to the extent reasonably
practicable. In addition, if any Portfolio incurs a significant loss or
liability, the Trustees have the authority to reduce pro rata the number of
shares of that Portfolio in each shareholder's account and to offset each
shareholder's pro rata portion of such loss or liability from the shareholder's
accrued but unpaid dividends or from future dividends.
 
    Securities of the Intermediate-Term Municipal, Pennsylvania Municipal and
New York Intermediate-Term Municipal Portfolios may be valued by the Manager
pursuant to valuations provided by an independent pricing service. The pricing
service relies primarily on prices of actual market transactions as well as
trader quotations. However, the service may also use a matrix system to
determine valuations, which system considers such factors as security prices,
yields, maturities, call features, ratings and developments relating to specific
securities in arriving at valuations. The procedures of the pricing service and
its valuations are reviewed by the officers of the Trust under the general
supervision of the Trustees.
 
                       PURCHASE AND REDEMPTION OF SHARES
 
    The Trust reserves the right to suspend the right of redemption and/or to
postpone the date of payment upon redemption for any period during which trading
on the New York Stock Exchange is restricted, or during the existence of an
emergency (as determined by the SEC by rule or regulation) as a result of which
disposal or evaluation of the portfolio securities is not reasonably
practicable, or for such other periods as the SEC may be order permit. The Trust
also reserves the right to suspend sales of shares of a Portfolio for any period
during which the New York Stock Exchange, the Manager, a Portfolio's Adviser,
the Distributor and/or the Custodian are not open for business.

                      SHAREHOLDER SERVICES--CLASS D SHARES
 
    STOP-PAYMENT REQUESTS (MONEY MARKET PORTFOLIOS ONLY):  Investors may request
a stop payment on checks by providing the Trust with a written authorization to
do so. Oral requests will be accepted provided that the Trust promptly receives
a written authorization. Such requests will remain in effect for six months
unless renewed or canceled. The Trust will use its best efforts to effect
stop-payment instructions, but does not promise or guarantee that such
instructions will be effective. Shareholders requesting stop payment will be
charged a $20 service fee per check which will be deducted from their accounts.
 
    EXCHANGE PRIVILEGE:  A shareholder may exchange the shares of the Tax Free
Portfolio for which good payment has been received, in his account at any time,
regardless of how long he has held his shares.
 
    Each Exchange Request must be in proper form (I.E., if in writing, signed by
the record owner(s) exactly as the shares are registered; if by telephone,
proper account identification is given by the dealer or shareholder of record),
and each exchange must involve either shares having an aggregate value of at
least $1,000 or all the shares in the account. Each exchange involves the
redemption of the shares of a Portfolio (the "Old Portfolio") to be exchanged
and the purchase at net asset value of the shares of the other portfolios (the
"New Portfolios") plus in certain cases, as disclosed in each Prospectus, any
applicable sales charge. Any gain or loss on the redemption of the shares
exchanged is reportable on the shareholder's federal income tax return, unless
such shares were held in a tax-deferred retirement plan or other tax-exempt
account. If the Exchange Request is received by the Distributor in writing or by
telephone on any business day prior to the redemption cut-off time specified in
each Prospectus, the exchange usually will occur on that day if all the
restrictions set forth above have been complied with at that time. However,
payment of the redemption proceeds by the Old Portfolio, and thus the purchase
of shares of the New Portfolios, may be delayed for up to seven days if the
Portfolios determine that such delay would be in the best interest of all of its
shareholders. Investment dealers which have satisfied criteria established by
the Portfolios may also communicate a shareholder's Exchange Request to the
Portfolios subject to the restrictions set forth above. No more than five
exchange requests may be made in any one telephone Exchange Request.
 
                                     TAXES
 
FEDERAL INCOME TAX
 
    The following discussion of federal income tax consequences is based on the
Internal Revenue Code of 1986, as amended (the "Code") and the regulations
issued thereunder as in effect on the date of this Statement of Additional
Information. New legislation, as well as administrative changes or court
decisions, may significantly change the conclusions expressed herein, and may
have a retroactive effect with respect to the transactions contemplated herein.
 
                                      S-18
<PAGE>
    Each Portfolio will decide whether to distribute or retain all or part of
any net capital gains (the excess of net long-term capital gains over net
short-term capital losses) in any year for reinvestment. If any such gains are
retained, the Portfolio will pay federal income tax thereon, and, if the
Portfolio makes an election, the shareholders will include such undistributed
gains in their income and shareholders subject to tax will be able to claim
their share of the tax paid by the Portfolio as a credit against their federal
income tax liability.
 
    A gain or loss realized by a shareholder on the sale or exchange of shares
of a Portfolio held as a capital asset will be capital gain or loss, and such
gain or loss will be long-term if the holding period for the shares exceeds one
year, and otherwise will be short-term. Any loss realized on a sale or exchange
will be disallowed to the extent the shares disposed of are replaced within the
61-day period beginning 30 days before and ending 30 days after the shares are
disposed of. Any loss realized by a shareholder on the disposition of shares
held 6 months or less is treated as a long-term capital loss to the extent of
any distributions of net long-term capital gains received by the shareholder
with respect to such shares or any inclusion of undistributed capital gain with
respect to such shares.
 
    Each Portfolio will generally be subject to a nondeductible 4% federal
excise tax to the extent it fails to distribute by the end of any calendar year
at least 98% of its ordinary income and 98% of its capital gain net income (the
excess of short- and long-term capital gains over short- and long-term capital
losses) for the one-year period ending on October 31 of that year, plus certain
other amounts.
 
    Each Portfolio is required by federal law to withhold 31% of reportable
payments (which may include dividends, capital gains distributions, and
redemptions) paid individual or non-corporate to shareholders who have not
certified on the Account Registration Form or on a separate form supplied by the
Portfolio, that the Social Security or Taxpayer Identification Number provided
is correct and that the shareholder is exempt from backup withholding or is not
currently subject to backup withholding.
 
    Each Portfolio within the Trust is generally treated as a separate
corporation for federal income tax purposes, and thus the provisions of the Code
generally will be applied to each Portfolio separately, rather than to the Trust
as a whole. Net long-term and short-term capital gains, net income, and
operating expenses therefore will be determined separately for each Portfolio.
 
    If a Portfolio fails to qualify as a regulated investment company ("RIC")
for any year, all of its income will be subject to tax at corporate rates, and
its distributions (including capital gains distributions) will be taxable as
ordinary income dividends to its shareholders, subject to the corporate
dividends received deduction for corporate shareholders. No dividends of any
Portfolio are expected to qualify for that deduction.
 
    As noted in the Prospectuses for the Portfolios, exempt-interest dividends
are excludable from a shareholder's gross income for regular federal income tax
purposes. Exempt-interest dividends may nevertheless be subject to the
alternative minimum tax (the "Alternative Minimum Tax") imposed by Section 55 of
the Code or the environmental tax (the "Environmental Tax") imposed by Section
59A of the Code. The Alternative Minimum Tax is imposed at the rate of 26% to
28% in the case of non-corporate taxpayers and at the rate of 20% in the case of
corporate taxpayers, to the extent it exceeds the taxpayer's regular tax
liability. The Environmental Tax is imposed at the rate of 0.12% and applies
only to corporate taxpayers. The Alternative Minimum Tax and the Environmental
Tax may be imposed in two circumstances. First, exempt-interest dividends
derived from certain "private activity bonds" issued after August 7, 1986, will
generally be an item of tax preference and therefore potentially subject to the
Alternative Minimum Tax for both corporate and non-corporate taxpayers and the
Environmental Tax for corporate taxpayers only. The Portfolios intend, when
possible, to avoid investing in private activity bonds. Second, in the case of
exempt-interest dividends received by corporate shareholders, all
exempt-interest dividends, regardless of when the bonds from which they are
derived were issued or whether they are derived from private activity bonds,
will be included in the corporation's "adjusted current earnings," as
 
                                      S-19
<PAGE>
defined in Section 56(g) of the Code, in calculating the corporation's
alternative minimum taxable income for purposes of determining the Alternative
Minimum Tax and the Environmental Tax.
 
    The percentage of income that constitutes "exempt-interest dividends" will
be determined for each year for the Portfolios and will be applied uniformly to
all dividends declared with respect to the Portfolios during that year. This
percentage may differ from the actual percentage for any particular day.
 
    Interest on indebtedness incurred by shareholders to purchase or carry
shares of the Portfolios will not be deductible for federal income tax purposes
to the extent that the Portfolios distribute exempt-interest dividends during
the taxable year. The deduction otherwise allowable to property and casualty
insurance companies for "losses incurred" will be reduced by an amount equal to
a portion of exempt-interest dividends received or accrued during any taxable
year. Certain foreign corporations engaged in a trade or business in the United
States will be subject to a "branch profits tax" on their "dividend equivalent
amount" for the taxable year, which will include exempt-interest dividends.
Certain Subchapter S corporations may also be subject to taxes on their "passive
investment income," which could include exempt-interest dividends. Up to 85% of
the Social Security benefits or railroad retirement benefits received by an
individual during any taxable year will be included in the gross income of such
individual if the individual's "modified adjusted gross income" (which includes
exempt-interest dividends) plus one-half of the Social Security benefits or
railroad retirement benefits received by such individual during that taxable
year exceeds the base amount described in Section 86 of the Code.
 
    Entities or persons who are "substantial users" (or persons related to
"substantial users") of facilities financed by industrial development bonds or
private activity bonds should consult their tax advisors before purchasing
shares of the Portfolios. "Substantial user" is defined generally as including a
"non-exempt person" who regularly uses in a trade or business a part of a
facility financed from the proceeds of industrial development bonds or private
activity bonds.
 
    Issuers of bonds purchased by the Portfolios (or the beneficiary of such
bonds) may have made certain representations or covenants in connection with the
issuance of such bonds to satisfy certain requirements of the Code that must be
satisfied subsequent to the issuance of such bonds. Investors should be aware
that exempt-interest dividends derived from such bonds may become subject to
federal income taxation retroactively to the date of issuance of the bonds to
which such dividends are attributable if such representations are determined to
have been inaccurate or if the issuer of such bonds (or the beneficiary of such
bonds) fails to comply with such covenants.
 
STATE TAXES
 
    A Portfolio is not liable for any income or franchise tax in Massachusetts
if it qualifies as a RIC for federal income tax purposes. Depending upon
applicable state and local law, shareholders of a Portfolio may be exempt from
state and local taxes on distributions of tax-exempt interest income derived
from obligations of the state and/or municipalities in which they reside, but
shareholders may be subject to tax on income derived from obligations of other
jurisdictions. Each Portfolio will make periodic reports to shareholders of the
source of distributions on a state-by-state basis.
 
    If a Portfolio qualifies to pay dividends to shareholders that are exempt
from California personal income tax ("California exempt-interest dividends"),
dividends distributed to shareholders will be considered California
exempt-interest dividends (1) if they are designated as exempt-interest
dividends by the Portfolio in a written notice to shareholders mailed within 60
days of the close of the Portfolio's taxable year and (2) to the extent the
interest received by the Portfolio during the year on California Tax Exempt
Obligations exceeds expenses of the Portfolio that would be disallowed under
California personal income tax law as allocable to tax exempt interest if the
Portfolio were an individual. If the aggregate dividends so designated exceed
the amount that may be treated as California exempt-interest dividends, only
that percentage of each dividend distribution equal to the ratio of aggregate
California exempt-interest dividends to aggregate dividends so designated will
be treated as a California exempt-interest dividend.
 
                                      S-20
<PAGE>
    For taxable years beginning after August 5, 1997, the Taxpayer Relief Act of
1997 repealed the 30 percent gross income test or "short-short" rules (the
"30-percent test") under which a regulated investment company had to derive less
than 30 percent of its gross income from the sale or disposition of certain
short-term assets held for less than three months. However, California has not
yet conformed to this federal legislation. Although the California legislature
may enact tax conforming legislation in 1998 that would be retroactive to August
5, 1997, no assurances can be given that California will provide a dividends
paid deduction to the Portfolio, or treat dividends paid by the Portfolio to its
shareholders as California exempt-interest dividends, if the Portfolio fails to
meet the 30-percent test. It is the intention of the management of the Portfolio
to continue to meet the 30-percent test for all years for which California does
not conform to the federal legislation.
 
    Shareholders should consult their tax advisors concerning the state and
local tax consequences of investments in the Trust, which may differ from the
federal income tax consequences described above.
 
                             PORTFOLIO TRANSACTIONS
 
    The Trust has no obligation to deal with any dealer or group of dealers in
the execution of transactions in portfolio securities. Subject to policies
established by the Trustees, the Advisers and Sub-Adviser are responsible for
placing orders to execute Portfolio transactions. In placing orders, it is the
Trust's policy to seek to obtain the best net results taking into account such
factors as price (including the applicable dealer spread), size, type and
difficulty of the transaction involved, the firm's general execution and
operational facilities, and the firm's risk in positioning the securities
involved. While the Advisers and Sub-Adviser generally seek reasonably
competitive spreads or commissions, the Trust will not necessarily be paying the
lowest spread or commission available. The Trust's policy of investing in
securities with short maturities will result in high portfolio turnover. The
Trust will not purchase portfolio securities from any affiliated person acting
as principal except in conformity with the regulations of the SEC.
 
    The Trust does not expect to use one particular dealer, but, subject to the
Trust's policy of seeking the best net results, dealers who provide supplemental
investment research to the Advisers and Sub-Adviser may receive orders for
transactions by the Trust. Information so received will be in addition to and
not in lieu of the services required to be performed by the Advisers or
Sub-Adviser under the Advisory or Sub-Advisory Agreements, and the expenses of
the Advisers and Sub-Adviser will not necessarily be reduced as a result of the
receipt of such supplemental information.
 
    The money market securities in which certain of the Portfolios invest are
traded primarily in the over-the-counter market. Bonds and debentures are
usually traded over-the-counter, but may be traded on an exchange. Where
possible, a Portfolio's Adviser or Sub-Adviser will deal directly with the
dealers who make a market in the securities involved except in those
circumstances where better prices and execution are available elsewhere. Such
dealers usually are acting as principal for their own account. On occasion,
securities may be purchased directly from the issuer. Money market securities
are generally traded on a net basis, and do not normally involve either
brokerage commissions or transfer taxes. The cost of executing portfolio
securities transactions of the Portfolio will primarily consist of dealer
spreads and underwriting commissions.
 
    It is expected that certain of the Portfolios may execute brokerage or other
agency transactions through the Distributor, a registered broker-dealer, for a
commission, in conformity with the 1940 Act, the Securities Exchange Act of
1934, as amended, and rules of the SEC. Under these provisions, the Distributor
is permitted to receive and retain compensation for effecting portfolio
transactions for a Portfolio on an exchange if a written contract is in effect
between the Distributor and the Trust expressly permitting the Distributor to
receive and retain such compensation. These provisions further require that
commissions paid to the Distributor by the Trust for exchange transactions not
exceed "usual and customary" brokerage commissions. The rules define "usual and
customary" commissions to include amounts which are "reasonable and fair
compared to the commission, fee or other remuneration received or to be received
by other brokers in connection with comparable transactions involving similar
securities
 
                                      S-21
<PAGE>
being purchased or sold on a securities exchange during a comparable period of
time." In addition, the Portfolios may direct commission business to one or more
designated broker-dealers, including the Distributor, in connection with payment
of certain of the Portfolios' expenses by such broker-dealers. The Trustees,
including those who are not "interested persons" of the Trust, have adopted
procedures for evaluating the reasonableness of commissions paid to the
Distributor and will review these procedures periodically.
 
    Since the Trust does not market its shares through intermediary brokers or
dealers, it is not the Trust's practice to allocate brokerage or principal
business on the basis of sales of its shares which may be made through such
firms. However, the Advisers and Sub-Adviser may place portfolio orders with
qualified broker-dealers who recommend the Trust to clients, and may, when a
number of brokers and dealers can provide best price and execution on a
particular transaction, consider such recommendations by a broker or dealer in
selecting among broker-dealers.
 
    The Advisers and Sub-Adviser may, consistent with the interests of the
Portfolios, select brokers on the basis of the research services they provide to
the Adviser or Sub-Adviser. Such services may include analysis of the business
or prospects of a company, industry or economic sector or statistical and
pricing services. Information so received by the Advisers or Sub-Adviser will be
in addition to and not in lieu of the services required to be performed by an
Adviser or Sub-Adviser under the Advisory or Sub-Advisory Agreements. If in the
judgement of an Adviser or Sub-Adviser the Portfolios, or other accounts managed
by the Adviser or Sub-Adviser, will be benefitted by supplemental research
services, the Adviser or Sub-Adviser is authorized to pay brokerage commissions
to a broker furnishing such services which are in excess of commissions which
another broker may have charged for effecting the same transaction. The expenses
of an Adviser or Sub-Adviser will not necessarily be reduced as a result of the
receipt of such supplemental information.
 
    For the fiscal years ended August 31, 1995, 1996, and 1997, the Portfolios
paid no brokerage commissions.
 
    It is expected that the portfolio turnover rate will normally not exceed
100% for any Portfolio. A portfolio turnover rate would exceed 100% if all of
its securities, exclusive of U.S. Government securities and other securities
whose maturities at the time of acquisition are one year or less, are replaced
in the period of one year. Turnover rates may vary from year to year and may be
affected by cash requirements for redemptions and by requirements which enable a
Portfolio to receive favorable tax treatment.
 
    For each of the fiscal years ending August 31, 1996 and 1997, the portfolio
turnover rate for each of the following Portfolios was:

                             DESCRIPTION OF SHARES
 
    The Declaration of Trust authorizes the issuance of an unlimited number of
shares of each Portfolio, each of which represents an equal proportionate
interest in that Portfolio. Each share upon liquidation entitles a shareholder
to a pro rata share in the net assets of that Portfolio, after taking into
account the Class D and CNI Class distribution expenses. Shareholders have no
preemptive rights. The Declaration of Trust provides that the Trustees of the
Trust may create additional portfolios of shares or classes of portfolios. Share
certificates representing the shares will not be issued.

<PAGE>
                       LIMITATION OF TRUSTEES' LIABILITY
 
    The Declaration of Trust provides that a Trustee shall be liable only for
his own willful defaults and, if reasonable care has been exercised in the
selection of officers, agents, employees or administrators, shall not be liable
for any neglect or wrongdoing of any such person. The Declaration of Trust also
provides that the Trust will indemnify its Trustees and officers against
liabilities and expenses incurred in connection with actual or threatened
litigation in which they may be involved because of their offices with the Trust
unless it is determined in the manner provided in the Declaration of Trust that
they have not acted in good faith in the reasonable belief that their actions
were in the best interests of the Trust. However, nothing in the Declaration of
Trust shall protect or indemnify a Trustee against any liability for his wilful
misfeasance, bad faith, gross negligence or reckless disregard of his duties.
 
                             SHAREHOLDER LIABILITY
 
    The Trust is an entity of the type commonly known as a "Massachusetts
business trust." Under Massachusetts law, shareholders of such a Trust could,
under certain circumstances, be held personally liable as partners for the
obligations of the Trust. Even if, however, the Trust were held to be a
partnership, the possibility of the shareholders' incurring financial loss for
that reason appears remote because the Trust's Declaration of Trust contains an
express disclaimer of shareholder liability for obligations of the Trust and
requires that notice of such disclaimer be given in each agreement, obligation
or instrument entered into or executed by or on behalf of the Trust or the
Trustees, and because, the Declaration of Trust provides for indemnification out
of the Trust property for any shareholders held personally liable for the
obligations of the Trust.
 
                                5% SHAREHOLDERS
 
    As of December 1, 1997, the following persons were the only persons who were
record owners (or to the knowledge of the Trust, beneficial owners) of 5% or
more of the shares of the Portfolios. The Trust believes that most of the shares
referred to below were held by the persons indicated in accounts for their
fiduciary, agency, or custodial customers.
