The purpose of the expense table and example is to assist the investor in
understanding the various costs and expenses that may be directly or indirectly
borne by investors in the Portfolio's Class A and Class B shares. The Portfolio
also offers Class C shares, which are subject to the same expenses, except that
Class C shares bear different shareholder servicing costs. A person who
purchases shares through an account with a financial institution may be charged
separate fees by that institution. Additional information may be found under

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, either meet
                      rating requirements imposed by Rule 2a-7 or, if not rated,
                      are determined to be of comparable quality by Weiss, Peck
                      & Greer, L.L.C., the Portfolio's investment adviser (the
                      "Adviser or "WPG"). 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
 
                                        5                                      
<PAGE>   6
 
                      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
                      securities (other than U.S. Government 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 (in accordance with
                      procedures adopted by the Trust's Board of Trustees) to be
                      of equivalent quality to rated securities in which the
                      Portfolio may invest. 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.
                             Although the Portfolio is governed by Rule 2a-7,
                      its investment policies are more restrictive than those
                      imposed by that Rule.
                             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. 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. However,
                      the Portfolio generally intends to be fully invested in
                      federally tax-exempt securities. The Portfolio will not
                      invest more than 10% of its total assets in securities
                      which are considered to be illiquid.
                             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
 
                                        6

                      Federal Reserve System or the Federal Deposit Insurance
                      Corporation and that 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.
 
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, 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 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 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, 1996, 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. WPG has been active since its founding
                      in managing portfolios of tax exempt securities. As of
                      September 30, 1996, total assets under management were
                      approximately $13 billion. The principal business address
                      of the Adviser is One New York Plaza, New York, New York
                      10004.
                             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, 1996 the Portfolio paid
                      advisory fees, after waivers, of .04% of its relative net
                      assets.

DISTRIBUTION
AND SHAREHOLDER
SERVICING
 
                      SEI Financial Services Company (the "Distributor"), a
                      wholly owned subsidiary of SEI Investments Company
                      ("SEI"), 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 Portfolio will pay the
                      Distributor 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. 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.
                             Under the Class B shareholder service plan, the
                      Portfolio will pay shareholder service fees to the
                      Distributor 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
                      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. Certain financial institutions offering
                      shares to their customers may be required to register as
                      dealers pursuant to state laws.
                             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 in its sole
                      discretion, institute one or more promotional incentive
                      programs, which will be paid by the Distributor from its
                      own resources. Under any such program, the Distributor
                      will provide promotional incentives, in the form of cash
                      or other compensation, including merchandise, airline
                      vouchers, trips and vacation packages, to all dealers
                      selling shares of the Portfolios. Such promotional
                      incentives will be offered uniformly to all dealers and
                      predicated upon the amount of shares of the Portfolio sold
                      by the dealer.
 
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. Institutions that use certain SEI
                      proprietary systems may place orders electronically
                      through those systems. State securities laws may require
                      banks and financial institutions purchasing shares for
                      their customers to register as dealers pursuant to state
                      laws. 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 are offered only to residents of states
                      in which the shares are eligible for purchase.
                             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 2:00 p.m., Eastern time 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 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
 
                                       10

                      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 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
 
                                       11                                      
<PAGE>   12
 
                      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 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.
                             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. 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
 
                                       13

                      Municipal Portfolio, Kansas Tax Free Income 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, 680 E. Swedesford Road, Wayne,
                      Pennsylvania, 19087.
 
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. 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,
 
                                       15

                      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 risk.
 
U.S. Government
Obligations           Obligations issued by the U.S. Treasury or issued or
                      guaranteed by agencies of the U.S. Government, including,
                      among others, the Federal Farm Credit Bank, the Federal
                      Housing Administration and the Small Business
                      Administration, and obligations issued or guaranteed by
                      instrumentalities of the U.S. Government, including, among
                      others, the Federal Home Loan Mortgage Corporation, the
                      Federal Land Banks and the U.S. Post Service. 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., Federal National Mortgage Association securities).
                      Guarantees of principal by agencies or instrumentalities
                      of the U.S. Government may be a guarantee of payment at
                      the maturity of the obligation so that in the event of a
                      default prior to maturity there might not be a market and
                      thus no means of realizing on the obligation prior to
                      maturity. Guarantees as to the timely payment of principal
                      and interest do not extend to the value or yield of these
                      securities not to the value of the Fund's shares.
 
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
 
                                       16                                      
<PAGE>   17
 
                      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, high grade debt
                      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.

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, either meet
                      the rating requirements imposed by Rule 2a-7 or, if not
                      rated, are determined to be of comparable quality by
                      Weiss, Peck & Greer, L.L.C., the Portfolio's investment
                      adviser (the "Adviser" or "WPG"). 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
 
                                        4                                      +
<PAGE>   24
 
                      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.
 
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
                      securities (other than U.S. Government 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 (in accordance with
                      procedures adopted by the Trust's Board of Trustees) to be
                      of equivalent quality to rated securities in which the
                      Portfolio may invest. 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.
                             Although the Portfolio is governed by Rule 2a-7,
                      its investment policies are more restrictive than those
                      imposed by that Rule.
                             The Portfolio may purchase securities on a
                      "when-issued" basis, and reserves the right to engage in
                      transactions involving standby commitments. 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. However,
                      the Portfolio generally intends to be fully invested in
                      federally tax-exempt securities. The Portfolio will not
                      invest more than 10% of its total assets in securities
                      which are considered to be illiquid.
                             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

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 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,
 
                                        6                                      +

                      equipment, personnel and facilities, and serves as
                      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 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 August 31, 1996, 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. WPG has been active since its founding
                      in managing portfolios of tax exempt securities. As of
                      September 30, 1996, total assets under management were
                      approximately $13 billion. The principal business address
                      of the Adviser is One New York Plaza, New York, New York
                      10004.
                             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, 1996 the Portfolio paid
                      advisory fees, after waivers, of .04% of its relative net
                      assets.
 
DISTRIBUTION
AND SHAREHOLDER
SERVICING
 
                      SEI Financial Services Company (the "Distributor"), a
                      wholly owned subsidiary of SEI Investments Company
                      ("SEI"), serves as the Portfolio's distributor pursuant to
                      a distribution agreement (the "Distribution Agreement")
                      with the Trust.
 
                                        7                                      +

                             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 C shareholder service plans, the
                      Portfolio will pay shareholder service fees to the
                      Distributor 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 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. Certain financial institutions offering
                      shares to their customers may be required to register as
                      dealers pursuant to state laws.
                             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 in its sole
                      discretion, institute one or more promotional incentive
                      programs, which will be paid by the Distributor from its
                      own resources. Under any such program, the Distributor
                      will provide promotional incentives, in the form of cash
                      or other compensation, including merchandise, airline
                      vouchers, trips and vacation packages, to all dealers
                      selling shares of the Portfolios. Such promotional
                      incentives will be offered uniformly to all dealers and
                      predicated upon the amount of shares of the Portfolio sold
                      by the dealer.

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. Institutions that use certain SEI
                      proprietary systems may place orders electronically
                      through those systems. State securities laws may require
                      banks and financial institutions purchasing shares for
                      their customers to register as dealers pursuant to state
                      laws. 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 are offered only to residents of states
                      in which the shares are eligible for purchase.
                             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 2:00 p.m., Eastern time 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 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 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),
 
                                       10                                      +

                      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 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
 
                                       11                                      +

                      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.
                             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. 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,
                      Kansas Tax Free Income 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.

                      Pennsylvania, 19087.
 
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. 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
 
                                       14                                      +

                      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 risk.
 
U.S. Government
Obligations           Obligations issued by the U.S. Treasury or issued or
                      guaranteed by agencies of the U.S. Government, including,
                      among others, the Federal Farm Credit Bank, the Federal
                      Housing Administration and the Small Business
                      Administration, and obligations issued or guaranteed by
                      instrumentalities of the U.S. Government, including, among
                      others, the Federal Home Loan Mortgage Corporation, the
                      Federal Land Banks and the U.S. Post Service. 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., Federal National Mortgage Association securities).
                      Guarantees of principal by agencies or instrumentalities
                      of the U.S. Government may be a guarantee of payment at
                      the maturity of the obligation so that in the event of a
                      default prior to maturity there might not be a market and
                      thus no means of realizing on the obligation prior to
                      maturity. Guarantees as to the timely payment of principal
                      and interest do not extend to the value or yield of these
                      securities not to the value of the Fund's shares.
 
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, high grade debt
                      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.

THE EXAMPLE SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE
EXPENSES. ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN.
 
The purpose of the expense table and example is to assist the investor in
understanding the various costs and expenses that may be directly or indirectly
borne by investors in the Portfolio's Class A shares. The Portfolio also offers
Class D shares, which are subject to the same expenses, except that Class D
shares bear different distribution and transfer agent costs. A person who
purchases shares through a financial institution may be charged separate fees by
that institution. Additional information regarding these differences may be
found under "The Manager," "Distribution and Shareholder Servicing" and "The
Adviser."

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, either meet
                      the rating requirements imposed by Rule 2a-7 or, if not
                      rated, are determined to be of comparable quality by
                      Weiss, Peck & Greer, L.L.C., the Portfolio's investment
                      adviser (the "Adviser"). 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                                      +

                      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
                      securities (other than U.S. Government 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 (in accordance with
                      procedures adopted by the Trust's Board of Trustees) to be
                      of equivalent quality to rated securities in which the
                      Portfolio may invest. 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.
                             Although the Portfolio is governed by Rule 2a-7,
                      its investment policies are more restrictive than those
                      imposed by that Rule.
                             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 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 alternative minimum tax. However, the
                      Portfolio generally intends to be fully invested in
                      federally tax-exempt securities. The Portfolio will not
                      invest more than 10% of its net assets in illiquid
                      securities.
                             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)
                      that are members of the Federal Reserve System or

                      published financial statements at the time of investment;
                      and repurchase agreements involving any of the foregoing
                      obligations.

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 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, dividend disbursing agent,
                      and shareholder servicing agent.

<PAGE>   46
 
                             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, 1996, 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, supervises and
                      administers the Portfolio's investment program. The
                      Adviser is independent of the Manager and SEI, 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 portfolios of tax exempt securities. As of
                      September 30, 1996, total assets under management were
                      approximately $13 billion. The principal business address
                      of the Adviser is One New York Plaza, New York, New York
                      10004.
                             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, 1996, the Portfolio
                      paid advisory fees, after waivers, of .04% of its relative
                      daily net assets.
 
DISTRIBUTION
AND SHAREHOLDER
SERVICING
 
                      SEI Financial Services Company (the "Distributor"), a
                      wholly-owned subsidiary of SEI Investments Company
                      ("SEI"), serves as the Portfolio's distributor pursuant to
                      a distribution agreement with the Trust. The Portfolio has
                      adopted a distribution plan for its Class D shares (the
                      "Class D Plan") pursuant to Rule 12b-1 under the 1940 Act.

                             The Portfolio has adopted a shareholder servicing
                      plan for Class A shares (the "Service Plan") under which a
                      shareholder servicing fee of up to .25% of average daily
                      net assets attributable to Class A shares will be paid to
                      the Distributor. 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.
                             In addition, the Distributor may, from time to time
                      in its sole discretion, institute one or more promotional
                      incentive programs, which will be paid by the Distributor
                      from its own resources. Under any such program, the
                      Distributor will provide promotional incentives, in the
                      form of cash or other compensation, including merchandise,
                      airline vouchers, trips and vacation packages, to all
                      dealers selling shares of the Portfolio. Such promotional
                      incentives will be offered uniformly to all dealers and
                      predicated upon the amount of shares of the Portfolio sold
                      by the dealer.
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. Institutions that use certain SEI
                      proprietary systems may place orders electronically
                      through those systems. State securities laws may require
                      banks and financial institutions purchasing shares for
                      their customers to register as dealers pursuant to state
                      laws. 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 are offered only to residents
                      of states in which the shares are eligible for purchase.
                             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 2:00 p.m., Eastern time 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,
                      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 order will be effective on the next Business
                      Day.
                             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 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 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.
                             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.

                      Portfolio is not deductible for federal income tax
                      purposes. 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.

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, Kansas Tax Free Income 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 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. 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.

                      Trust. Arthur Andersen LLP serves as the independent
                      public accountants of the Trust.

                      the Trust. The Custodian holds cash, securities and other

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 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, including,
                      among others, the Federal Farm Credit Bank, the Federal
                      Housing Administration and the Small Business
                      Administration, and obligations issued or guaranteed by
                      instrumentalities of the U.S. Government, including, among
                      others, the Federal Home Loan Mortgage Corporation, the
                      Federal Land Banks and the U.S. Post Service. 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., Federal National Mortgage
 
                                       14                                      +

                      Association securities). Guarantees of principal by
                      agencies or instrumentalities of the U.S. Government may
                      be a guarantee of payment at the maturity of the
                      obligation so that in the event of a default prior to
                      maturity there might not be a market and thus no means of
                      realizing on the obligation prior to maturity. Guarantees
                      as to the timely payment of principal and interest do not
                      extend to the value or yield of these securities not to
                      the value of the Fund's shares.
 
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, high grade debt
                      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.

YOUR ACCOUNT
AND DOING BUSINESS
WITH US               You may open an account with just $1,000, and make
                      additional investments with as little as $100. Redemptions
                      of the Portfolio's shares are made at net asset value per
                      share. See "Your Account and Doing Business With Us."

DIVIDENDS             Substantially all of the net
                      investment income (exclusive
                      of capital gains) of the
                      Portfolio is distributed in 
                      the form of dividends that 
                      will be declared daily and paid
                      monthly on the first Business
                      Day of each month. Any
                      realized net capital gain is
                      distributed at least
                      annually. Distributions are
                      paid in additional shares
                      unless the shareholder elects
                      to take the payment in cash.
                      See "General Information--

THE EXAMPLE SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE EXPENSE.
ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN.
 
The purpose of the expense table and example is to assist the investor in
understanding the various costs and expenses that may be directly or indirectly
borne by investors in the Portfolio's Class D shares. The Portfolio also offers
Class A shares, which are subject to the same expenses as the Portfolio's Class
D shares, except that Class A shares bear different shareholder servicing and
transfer agent costs. A person that purchases shares through an account with a
financial institution may be charged separate fees by the financial institution.

Agent," "Distribution," and "The Adviser."
 
Long-term shareholders may pay more than the economic equivalent of the maximum
front end sales charges permitted by the Conduct Rules of the National

HOW TO BUY, SELL
AND EXCHANGE
SHARES THROUGH
INTERMEDIARIES        Class D shares of the Portfolio may be purchased through
                      Intermediaries which provide various levels of shareholder
                      services to their customers. Contact your Intermediary for
                      information about the services available to you and for
                      specific instructions on how to buy,
                      sell and exchange shares. To
                      allow for processing and
                      transmittal of orders to the
                      Transfer 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
                      shareholder services and any
                      charges will be provided to
                      the customer by the
                      Intermediary. Certain of these Intermediaries may be
                      required to register as broker-dealers under state law.
                             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.
 
HOW TO BUY SHARES
FROM THE TRANSFER
AGENT
                      Account application forms may be obtained by calling
                      1-800-437-6016. Class D shares of the Portfolio are
                      offered only to residents of states in which the shares
                      are eligible for purchase.
 
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. 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 shares are
                      purchased by check, redemption proceeds will be forwarded
                      only upon collection of payment for such shares;
                      collection of payment may take up to 15 days.

                                                     Any entity, such as a
                                                     bank, broker-dealer,
                                                     other financial

                                                     or organization which
                                                     has entered into an
                                                     arrangement with the
                                                     Distributor to sell
                                                     Class D shares to its
                                                     customers.

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.
 
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.
                             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. Telephone
                      exchanges will also be accepted if you previously elected
                      this option on your account application.
 
                                                               HOW DOES AN

                                                     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.

                             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
By Mail
                      To sell your shares, a written request for redemption in
                      good order must be received by the Transfer 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.
                             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.
 
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
                                                               WHAT IS A

                                                     A signature guarantee
                                                     verifies the
                                                     authenticity of your
                                                     signature and may be

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, either meet
                      the rating requirements imposed by Rule 2a-7 or, if not
                      rated, are determined to be of comparable quality by
                      Weiss, Peck & Greer, L.L.C., the Portfolio's investment
                      adviser (the "Adviser"). 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

                                                     The Portfolio's
                                                     investment objective is
                                                     a statement of what it
                                                     seeks to achieve. It is
                                                     important to make sure
                                                     that the investment
                                                     objective matches your
                                                     own financial needs and
                                                     circumstances. The

                      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.
 
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
                      securities (other than U.S. Government 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 (in accordance with
                      procedures adopted by the Trust's Board of Trustees) to be
                      of equivalent quality to rated securities in which the
                      Portfolio may invest. 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.
                             Although the Portfolio is governed by Rule 2a-7,
                      its investment policies are more restrictive than those
                      imposed by that Rule.
                             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.
                             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
 
                                       10

                      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 the foregoing obligations.
                             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.
 
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,
                         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
AND SHAREHOLDER
SERVICING AGENT
 
                      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 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, 1996, the
                      Portfolio paid management fees, after waivers, of .36% of
                      its average daily net assets.
                             The Trust and DST Systems, Inc., 1004 Baltimore
                      Street, 2nd Floor, Kansas City, Missouri, 64105 ("DST"),
                      have entered into a separate transfer agent agreement,

                                                     activities and is

                      management were approximately $13 billion. The principal
                      business address of the Adviser is One New York Plaza, New
                      York, New York 10004.

                             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, 1996, the Portfolio
                      paid advisory fees, after waivers, of .04% of its relative
                      net assets.
 
DISTRIBUTION
 
                      SEI Financial Services Company (the "Distributor"), a
                      wholly-owned subsidiary of SEI Investments Company
                      ("SEI"), 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 in its sole
                      discretion, institute one or more promotional incentive
                      programs, which will be paid for by the Distributor

                      from the sales charge it receives or from its own
                      resources. Under any such program, the Distributor will
                      provide promotional incentives, in the form of cash or
                      other compensation, including merchandise, airline
                      vouchers, trips and vacation packages, to all dealers
                      selling shares of the Portfolio. Such promotional
                      incentives will be offered uniformly to all shares of the
                      Portfolio and also will be offered uniformly to all
                      dealers, predicated upon the amount of shares of the
                      Portfolio sold by such dealer.
 
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 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.
                             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

                      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.

                             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. 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.

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"). However, shares of the Portfolio cannot be
                      purchased by Federal Reserve wire on federal holidays
                      restricting wire transfers. 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 receives the order and, in the case of a purchase
                      request, payment before 2:00 p.m., Eastern time. 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 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 of the redemption order.
 
How the               The net asset value per share of the Portfolio is
Net Asset Value       determined by dividing the total market value of its
is Determined         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        Redemption orders may be placed by telephone. Neither the
Instructions          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, and you experience
                      difficulties placing redemption orders by telephone, you
                      may wish to consider placing your order by other means.

                      your original investment could be exhausted entirely. To
                      participate in the SWP, you must have your dividends

                      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

                      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:

                      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

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 shareholders'
                      approval will be sought for certain changes in the
                      operation of the
 
                                       19

                      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 Street, 2nd
                      Floor, 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.

                      Trust. Arthur Andersen LLP serves as the independent
                      public 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 obligation 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 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, including,
                      among others, the Federal Farm Credit Bank, the Federal
                      Housing Administration and the Small Business
                      Administration, and obligations issued or guaranteed by
                      instrumentalities of the U.S. Government, including, among
                      others, the Federal Home Loan Mortgage Corporation, the
                      Federal Land Banks and the U.S. Post Service. 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., Federal National Mortgage Association securities).
                      Guarantees of principal by agencies or instrumentalities
                      of the U.S. Government may be a guarantee of payment at
                      the maturity of the obligation so that in the event of a
                      default prior to maturity there might not be a market and
                      thus no means of realizing on the obligation prior to
                      maturity. Guarantees as to the timely payment of principal
                      and interest do not extend to the value or yield of these
                      securities not to the value of the Fund's shares.
 
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, high grade debt
                      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.

THE EXAMPLE SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE
EXPENSES. ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN.
 
The purpose of the expense table and example is to assist the investor in
understanding the various costs and expenses that may be directly or indirectly
borne by investors in the Portfolio's Class A, Class B and Class C shares. The
Portfolio also offers Class G shares, which are subject to the same expenses,
except for different distribution and shareholder servicing expenses. A person
who purchases shares through a financial institution may be charged separate
fees by that institution. Additional information may be found under "The
Manager," "The Adviser" and "Distribution and Shareholder Servicing."
 
Long-term shareholders may pay more than the economic equivalent of the maximum
front end sales charges permitted the Conduct Rules of the National Association
of Securities Dealers, Inc.

INVESTMENT
OBJECTIVES 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 (including
                      repurchase agreements, U.S. Treasury securities and
                      instruments of certain U.S. commercial banks or savings
                      and loan institutions).
                             The Adviser will not invest more than 25% of
                      Portfolio 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
 
                                        4                                      
<PAGE>   87
 
                       categories: public housing authorities; general
                       obligations of states and localities; state and local
                       housing finance authorities or municipal utilities
                       systems.
 
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
                      securities (other than U.S. Government 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 (in accordance with
                      procedures adopted by the Trust's Board of Trustees) to be
                      of equivalent quality to rated securities in which the
                      Portfolio may invest. 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.
                             Although the Portfolio is governed by Rule 2a-7,
                      its investment policies are more restrictive than those
                      imposed by that Rule.
                             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.

                      investments and ratings, see the "Description of Permitted
                      Investments and Risk Factors" and the Statement of

RISK
FACTORS
 
California Risk Factors
                      The Portfolio's concentration in investments in California
                      municipal securities involves greater risks than other
                      types of money market funds. Certain risks are inherent in
                      the Portfolio's investments in California municipal
                      securities. These risks result from (1) amendments to the
                      California Constitution and other statutes that limit the
                      taxing and spending authority of California government
                      entities, (2) the general financial condition of the State
                      of California, and (3) a variety of California laws and
                      regulations that may affect, directly or indirectly,
                      California 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. A more complete description of these risks is
                      contained in the Statement of Additional Information.
                             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.
 
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.
 
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, 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 .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, 1996, the Portfolio paid management fees,
                      after waivers, of .20% 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 programs of the Portfolio. The
                      Adviser is independent of the Manager and SEI 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 portfolios of tax exempt securities. As of
                      September 30, 1996, total assets under management were
                      approximately $13 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 WPG, has been
                      associated with WPG'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, 1996, the Portfolio paid advisory fees, after
                      waivers, of .04% of its relative net assets.
 
DISTRIBUTION
AND SHAREHOLDER
SERVICING
 
                      SEI Financial Services Company (the "Distributor"), a
                      wholly owned subsidiary of SEI Investments Company
                      ("SEI"), 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 such third party.
                             Under the Class A plan, the Portfolio will pay the
                      Distributor 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
                      Portfolio will pay shareholder service fees to the
                      Distributor 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 compensation with respect to different classes.
                      These financial institutions may also charge separate fees
                      to their customers. Certain financial institutions
                      offering shares to their customers may be required to
                      register as dealers pursuant to state laws.
                             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 in its sole
                      discretion, institute one or more promotional incentive
                      programs, which will be paid by the Distributor from its
                      own resources. Under any such program, the Distributor
                      will provide promotional incentives, in the form of cash
                      or other compensation, including merchandise, airline
                      vouchers, trips and vacation packages, to all dealers
                      selling shares of the Portfolio. Such promotional
                      incentives will be offered uniformly to all dealers and
                      predicated upon the amount of shares of the Portfolio sold
                      by the dealer.
 
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. Institutions that use certain SEI
                      proprietary systems may place orders electronically
                      through those systems. State securities laws may require
                      banks and financial institutions purchasing shares for
                      their customers to register as dealers pursuant to state
                      laws. 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 are offered only to residents of states
                      in which the shares are eligible for purchase.
                             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. The Trust reserves
                      the right to reject a purchase order when the
 
                                        9

                      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 liability, 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, the
                      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.
                             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
 
                                       10                                      
<PAGE>   93
 
                       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
                       Class G shares because of the additional distribution
                       and/or shareholder servicing expenses charged to Class B,
                       Class C and Class G 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.
 
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 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. 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% 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 Trust
                      consists of the following portfolios: Tax Free Portfolio,
                      Institutional Tax Free Portfolio, Intermediate-Term
                      Municipal Portfolio, Pennsylvania Municipal Portfolio,
                      Kansas Tax Free Income 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. 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.
                             The dividends on Class A shares of the Portfolio
                      are normally higher than those on Class B, Class C or
                      Class G shares because of the additional distribution
                      and/or shareholder servicing expenses charged to Class B,
                      Class C and Class G 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
                      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 risk.
 
U.S. Government
Obligations           Obligations issued by the U.S. Treasury or issued or
                      guaranteed by agencies of the U.S. Government, including,
                      among others, the Federal Farm Credit Bank, the Federal
                      Housing Administration and the Small Business
                      Administration, and obligations issued or guaranteed by
                      instrumentalities of the U.S. Government, including, among
                      others, the Federal Home Loan Mortgage Corporation, the
                      Federal Land Banks and the U.S. Post Service. 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., Federal National Mortgage Association securities).
                      Guarantees of principal by agencies or instrumentalities
                      of the U.S. Government may be a guarantee of payment at
                      the maturity of the obligation so that in the event of a
                      default prior to maturity there might not be a market and
                      thus no means of realizing on the obligation prior to
                      maturity. Guarantees as to the timely payment of principal
                      and interest do not extend to the value or yield of these
                      securities not to the value of the Fund's shares.
 
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, high grade debt
                      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.

SEI Tax Exempt Trust (the "Trust") is an open-end investment management company,

portfolio.

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.

INVESTMENT
OBJECTIVES 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"
                      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 in taxable
                      money market securities (including repurchase agreements,
                      U.S. Treasury securities and instruments of certain U.S.
                      commercial banks or savings and loan institutions).
                             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.
 
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
                      securities (other than U.S. Government 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 (in accordance with
                      procedures adopted by the Trust's Board of Trustees) to be
                      of equivalent quality to rated securities in which the
                      Portfolio may invest. 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.
                             Although the Portfolio is governed by Rule 2a-7,
                      its investment policies are more restrictive than those
                      imposed by that Rule.
                             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 California
                      municipal securities involves greater risks than other
                      types of money market funds. These risks result from (1)
                      amendments to the California Constitution and other
                      statutes that limit the taxing and spending authority of
                      California government entities, (2) the general financial
                      condition of the State of California, and (3) a variety of
                      California laws and regulations that may affect, directly
                      or indirectly, California 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. A more complete description of these
                      risks is contained in the Statement of Additional
                      Information.
                             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.
 
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.

                      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, 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 .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 G shares of the Portfolio (as a
                      percentage of the Portfolio's average daily net assets
                      attributable to Class G 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, 1996,
                      the Portfolio paid management fees, after waivers, of .20%
                      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 programs 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, 1996, total assets under management
                      were approximately $13 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 WPG, has been
                      associated with WPG'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, 1996, the Portfolio paid advisory fees, after
                      waivers, of .04% of its relative net assets.
 
DISTRIBUTION
AND SHAREHOLDER
SERVICING
 
                      SEI Financial Services Company (the "Distributor"), a
                      wholly owned subsidiary of SEI Investments Company
                      ("SEI"), serves as the Portfolio's distributor pursuant to
                      a distribution agreement (the "Distribution Agreement")
                      with the Trust.
                             The Rule 12b-1 Plan applicable to Class G shares of
                      the Portfolio ("Class G Plan") provides for payments to
                      the Distributor at an annual rate of .50% of the
                      Portfolio's average daily net assets attributable to Class
                      G 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 Class G 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 "Class G Service Plan") under which firms,
                      including the Distributor, that provide shareholder
                      services may receive compensation therefor. Under the
                      Class G Service Plan, the Portfolio will pay shareholder
                      service fees to the Distributor 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,
                      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 provide
                      those services itself or may enter into arrangements under
                      which third
 
                                        8                                      +

parties provide such services and are compensated by the Distributor. The
Distributor may retain as a profit any difference between the fee it receives
and the amount it pays such third party.
                             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 compensation with respect to different
                      classes. These financial institutions may also charge
                      separate fees to their customers. Certain financial
                      institutions offering shares to their customers may be
                      required to register as dealers pursuant to state laws.
                             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 in its sole
                      discretion, institute one or more promotional incentive
                      programs, which will be paid by the Distributor from its
                      own resources. Under any such program, the Distributor
                      will provide promotional incentives, in the form of cash
                      or other compensation, including merchandise, airline
                      vouchers, trips and vacation packages, to all dealers
                      selling shares of the Portfolio. Such promotional
                      incentives will be offered uniformly to all dealers and
                      predicated upon the amount of shares of the Portfolio sold
                      by the dealer.
 
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. Institutions that use certain SEI
                      proprietary systems may place orders electronically
                      through those systems. State securities laws may require
                      banks and financial institutions purchasing shares for
                      their customers to register as dealers pursuant to state
                      laws. 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 are offered only to residents of states
                      in which the shares are eligible for purchase.
                             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 liability, 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.
                             The market value of the portfolio security is
                      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 of 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 most recently quoted bid price on each
                      Business Day.
                             Shareholders who desire to redeem shares of the
                      Portfolio must place their redemption orders with the
                      Transfer Agent prior to the calculation of net asset value
                      on any Business Day in order to be effective on that day.
                      Otherwise, the redemption orders will be effective on the
                      next Business Day. Payment for redemption orders from the
                      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 (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
                      Class G shares because of the additional distribution
                      and/or shareholder servicing expenses charged to Class B,
                      Class C and Class G 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.
 
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
 
                                       11                                      +

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.
                             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. 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.
 
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,
 
                                       13                                      +

Institutional Tax Free Portfolio, Intermediate-Term Municipal Portfolio,
Pennsylvania Municipal Portfolio, Kansas Tax Free Income 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, 680 E. Swedesford Road, Wayne,
                      Pennsylvania, 19087.
 
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 by the
                      Portfolio on the first Business Day of each 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.

                             The dividends on Class A shares of the Portfolio
                      are normally higher than those on Class B, Class C or
                      Class G shares because of the additional distribution
                      and/or shareholder servicing expenses charged to Class B,
                      Class C and Class G 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 and U.S. branches of foreign banks; (ii) U.S.
                      Treasury obligations and obligations issued by the
                      agencies and instrumentalities of the U.S. Government;
                      (iii) high-quality commercial paper issued by U.S. and
                      foreign corporations; (iv) debt obligations with a
                      maturity of one year or less issued by corporations that
                      issue high-quality commercial paper; and (v) 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 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, including,
                      among others, the Federal Farm Credit Bank, the Federal
                      Housing Administration, and the Small Business
                      Administration and obligations issued or guaranteed by
                      instrumentalities of the U.S. Government, including, among
                      others, the Federal Home Loan Mortgage Corporation, the
                      Federal Land Banks and the U.S. Post Service. 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., Federal National Mortgage Association securities).
                      Guarantees of principal by agencies or instrumentalities
                      of the U.S. Government may be a guarantee of payment at
                      the maturity of the obligation so that in the event of a
                      default prior to maturity there might not be a market and
                      thus no means of realizing on the obligation prior to
                      maturity. Guarantees as to the timely payment of principal
                      and interest do not extend to the value or yield of these
                      securities not to the value of the Fund's shares.

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, high grade debt
                      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.

INVESTMENT
OBJECTIVE 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.
                             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
 
                                        4

                      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. The Portfolio will 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 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.

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 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, 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 .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
 
                                        6                                      
<PAGE>   128
 
                      ended August 31, 1996, the Portfolio paid management fees,
                      after waivers, of .20% of its average daily net assets.

                      subsidiary of SEI Investments Company ("SEI"), a financial
                      services company located in Wayne, Pennsylvania. The

                      banks, institutional investors, investment advisers and
                      insurance companies. Affiliates of SFM have provided
                      consulting advice to institutional investors for more than
                      20 years, including advice regarding the selection and
                      evaluation of investment advisers. SFM currently serves as
                      manager or administrator to more than 39 investment
                      companies, including more than 290 portfolios, which
                      investment companies have more than $66 billion in assets
                      as of September 30, 1996.
                             SFM acts as the investment adviser to the Portfolio
                      and operates as a "manager of managers." As Adviser, SFM
                      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
                      SFM, 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 of SFM, which
                      evaluate quantitatively and qualitatively the
                      sub-advisers' skills and investment results in managing
                      assets for specific asset classes, investment styles and
                      strategies. Subject to Board review, SFM allocates and,
                      when appropriate, reallocates the Portfolio's assets to
                      the sub-advisers, monitors and evaluates the sub-advisers'
                      performance, and oversees sub-adviser compliance with the
                      Portfolio's investment objectives, policies and
                      restrictions. SFM HAS THE ULTIMATE RESPONSIBILITY FOR THE
                      INVESTMENT PERFORMANCE OF THE PORTFOLIO DUE TO ITS
                      RESPONSIBILITY TO OVERSEE SUB-ADVISERS AND RECOMMEND THEIR
                      HIRING, TERMINATION AND REPLACEMENT.
                             For these advisory services, SFM 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, 1996, the
                      Portfolio paid advisory fees, after waivers, of .33% of
                      its average daily net assets. SFM pays the sub-advisers
                      out its investment advisory fees.
                             SFM has obtained an exemptive order from the
                      Securities and Exchange Commission ("SEC") that permits
                      SFM, with the approval of the Trust's Board of Trustees,
                      to retain sub-advisers unaffiliated with SFM 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 SFM 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 Financial Services Company (the "Distributor"), a
                      wholly-owned subsidiary of SEI, 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 a
                      shareholder servicing fee of up to .25% of average daily
                      net assets attributable to Class A shares will be paid to
                      the Distributor. 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.
                             In addition, the Distributor may, from time to time
                      in its sole discretion, institute one or more promotional
                      incentive programs, which will be paid by the Distributor
                      from its own resources. Under any such program, the
                      Distributor will provide promotional incentives, in the
                      form of cash or other compensation, including merchandise,
                      airline vouchers, trips and vacation packages, to all
                      dealers selling shares of the Portfolio. Such promotional
                      incentives will be offered uniformly to all dealers and
                      predicated upon the amount of shares of the Portfolio sold
                      by the dealer.
 
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. Institutions that use certain SEI
                      proprietary systems may place orders electronically
                      through those systems. State securities laws may require
                      banks and financial institutions purchasing shares for
                      their customers to register as dealers pursuant to state
                      laws. 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 are offered only to residents of states
                      in which the shares are eligible for purchase.
                             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 close of trading on the New
                      York Stock Exchange (presently 4:00 p.m. Eastern time) 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 on the next
                      Business Day following the date 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 liability, 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. Although the methodology and
                      procedures for determining net asset value per share are
                      identical for all classes of the Portfolio, the net asset
                      value of one class may differ from that of another class
                      because of the different distribution fees charged to each
                      class.
                             The market value of each security is 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 of the pricing service and its valuation
                      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 most recently quoted bid price 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 the
                      close of trading on the New York Stock Exchange (presently
                      4:00 p.m. Eastern time) 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.
                             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

                      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
                      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.

                             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. 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, Kansas Tax
                      Free Income 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 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
 
                                       13

                      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, 680 E. Swedesford Road, Wayne,
                      Pennsylvania, 19087.
 
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.

Public Accountants    Morgan, Lewis & Bockius LLP serves as counsel to the
                      Trust. Arthur Andersen LLP serves as the independent
                      public 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
 
                                       14
<PAGE>   136
 
                      (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 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, including,
                      among others, the Federal Farm Credit Bank, the
 
                                       15
<PAGE>   137
 
                      Federal Housing Administration and the Small Business
                      Administration, and obligations issued or guaranteed by
                      instrumentalities of the U.S. Government, including, among
                      others, the Federal Home Loan Mortgage Corporation, the
                      Federal Land Banks and the U.S. Post Service. 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., Federal National Mortgage Association securities).
                      Guarantees of principal by agencies or instrumentalities
                      of the U.S. Government may be a guarantee of payment at
                      the maturity of the obligation so that in the event of a
                      default prior to maturity there might not be a market and
                      thus no means of realizing on the obligation prior to
                      maturity. Guarantees as to the timely payment of principal
                      and interest do not extend to the value or yield of these
                      securities not to the value of the Fund's shares.
 
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, high grade debt
                      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.

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, 1996 has been filed
with the Securities and Exchange Commission and is available upon request and
without charge by writing the Distributor, SEI Financial Services Company, 680
East Swedesford Road, Wayne, Pennsylvania 19087, 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 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 OR ANY STATE SECURITIES COMMISSION, NOR HAS THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES 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.

                      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, 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 maintain a
                      dollar-weighted average portfolio maturity of seven years
                      or less. Each security purchased will have an average
                      maturity of no longer than fifteen years.
 
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
                      (including repurchase agreements, U.S. Treasury securities
                      and obligations of certain U.S. commercial banks or
                      savings and loan institutions).
                             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,
                      either meet the rating requirements imposed by Rule 2a-7
                      or, if not rated, are determined to be of comparable
                      quality by Weiss, Peck & Greer L.L.C., this Portfolio's
                      investment adviser. 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
                      securities (other than U.S. Government 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 (in accordance with
                      procedures adopted by the Trust's Board of Trustees) to be
                      of equivalent quality to rated securities in which the
                      Money Market Portfolio may invest. 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.
                             Although the Money Market Portfolio is governed by
                      Rule 2a-7, its investment policies are more restrictive
                      than those imposed by that Rule.
                             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.
 
RISK FACTORS
 
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 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 other types of money market funds
                      because the concentration in securities of relatively few
                      Pennsylvania municipal issuers. 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
                         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 investment
                      limitations are set forth in the Statement of Additional
                      Information.

                      space, equipment, personnel and facilities, and serves as
                      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 .35% of the average daily net assets of the
                      Fixed 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

                      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,
                      1996, the Fixed Income and Money Market Portfolios paid
                      management fees, after waivers, of .24% and .27%,
                      respectively, of their average daily net assets.

                      is calculated daily and paid monthly, at an annual rate of

                      daily net assets.
 
DISTRIBUTION
AND SHAREHOLDER
SERVICING
 
                      SEI Financial Services Company (the "Distributor"), a
                      wholly owned subsidiary of SEI Investments Company
                      ("SEI"), 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 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, a Portfolio will pay the
                      Distributor 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, a Portfolio will pay
                      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 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. Certain financial institutions offering
                      shares to their customers may be required to register as
                      dealers pursuant to state laws.
                             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 in its sole
                      discretion, institute one or more promotional incentive
                      programs, which will be paid by the Distributor from its
                      own resources. Under any such program, the Distributor
                      will provide promotional incentives, in the form of cash
                      or other compensation, including merchandise, airline
                      vouchers, trips and vacation packages, to all dealers
                      selling shares of the Portfolios. Such promotional
                      incentives will be offered uniformly to all dealers and
                      predicated upon the amount of shares of the Portfolios
                      sold by the dealer.
 
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. Institutions that
                      use certain SEI proprietary systems may place orders
                      electronically through those systems. State securities
                      laws may require banks and financial institutions
                      purchasing shares for their customers to register as
                      dealers pursuant to state laws. 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 either Portfolio are offered only
                      to residents of states in which the shares are eligible
                      for purchase.
                             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
                      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 a specified time on any
                      Business Day for the order to be accepted on that Business
                      Day; the specified time is 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)

                      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
                      liability, 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.
                             Although the methodology and procedures for
                      determining net asset value per share are identical for
                      all classes of a Portfolio, the net asset value per share
                      of one class of the Fixed Income Portfolio may differ from
                      that of another class because of the different fees
                      charged to each class. 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 market value of each portfolio security of the
                      Fixed Income Portfolio is 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 of 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 most recently quoted bid
                      price on each Business Day.
                             Shareholders who desire to redeem shares of a
                      Portfolio must place their redemption orders with the

                      redemption order is received. Payment for redemption

                      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 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 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.
                             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
 
                                       13
<PAGE>   153
 
                      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 of the Money Market
                      Portfolio.
                             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 will normally be
                      higher than that of Class B or Class C shares 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.
 
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
 
                                       14                                      +

                      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 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. 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.

                             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.
 
State 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 or the United
                      States. 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.
                             Shares of the Portfolios are exempt from
                      Pennsylvania county personal property taxes to the extent
                      that the Portfolios' investments consist of obligations
                      which are themselves exempt from taxation in Pennsylvania.
                             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, Kansas
                      Tax Free Income 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 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, 680 E. Swedesford Road, Wayne,
                      Pennsylvania, 19087.
 
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
 
                                       17                                      +

                      to receive that day's dividend. The Money Market Portfolio
                      pays dividends on the first Business Day of each 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.

                      Trust. Arthur Andersen LLP serves as the independent

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
 
                                       18                                      +

                      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 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, including,
                      among others, the Federal Farm Credit Bank, the Federal
                      Housing Administration and the Small Business
                      Administration, and obligations issued or guaranteed by
                      instrumentalities of the U.S. Government, including, among
                      others, the Federal Home Loan Mortgage Corporation, the
                      Federal Land Banks and the U.S. Post Service. 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., Federal National Mortgage Association securities).
                      Guarantees of principal by agencies or instrumentalities
                      of the U.S. Government may be a guarantee of payment at
                      the maturity of the obligation so that in the event of a
                      default prior to maturity there might not be a market and
                      thus no means of realizing on the obligation prior to
                      maturity.
 
                                       19                                      +

                      Guarantees as to the timely payment of principal and
                      interest do not extend to the value or yield of these
                      securities not to the value of the Fund's shares.
 
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. The Portfolio will maintain with the
                      custodian a separate account with liquid, high grade debt
                      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. 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.

                              SEI TAX EXEMPT TRUST

                        KANSAS TAX FREE INCOME PORTFOLIO

                       SUPPLEMENT DATED DECEMBER 31, 1996
                   TO THE PROSPECTUS DATED DECEMBER 31, 1996

THIS SUPPLEMENT TO THE PROSPECTUS CONTAINS INFORMATION BEYOND THAT CONTAINED IN
THE PROSPECTUS AND SHOULD BE READ IN CONJUNCTION WITH THE PROSPECTUS.

At a meeting held on November 25, 1996, the Board of Trustees of SEI Tax Exempt
Trust (the "Trust") determined that it was in the best interests of
shareholders of the Trust's Kansas Tax Free Income Portfolio (the "Portfolio")
to reorganize the Portfolio with and into the INTRUST Funds Trust Kansas
Tax-Exempt Bond Fund (the "INTRUST Fund"), a newly-formed series of INTRUST
Funds Trust, a newly-organized management investment company. In accordance
with an agreement and plan of reorganization approved by the Trust's Board of
Trustees, the assets of the Portfolio will be transferred to the INTRUST Fund
in exchange for shares of the INTRUST Fund, and these shares will thereafter be
distributed to the shareholders of the Portfolio in liquidation of the
Portfolio.

The Portfolio will be reorganized with and effectively merged into the INTRUST
Fund only upon approval by shareholders of the Portfolio. It is anticipated
that the Board of Trustees of the Trust will call for a shareholder meeting to
be held in the second quarter of 1997, at which shareholders of the Portfolio
will be asked to approve an agreement and plan of reorganization relating to
the proposed reorganized transaction involving the Portfolio. Proxy materials
will be distributed to shareholders in advance of the meeting.

INVESTMENT
OBJECTIVE AND
POLICIES
 
                      The Portfolio's investment objective is to preserve
                      capital while producing current income for the investor
                      that is exempt from both federal and Kansas state income
                      taxes. There can be no assurance that the Portfolio will
                      meet its investment objective.
                             Under normal conditions the Portfolio will invest
                      at least 80% of its net assets in municipal obligations
                      which produce interest that is, in the opinion of bond
                      counsel for the issuer, exempt from federal income tax
                      (collectively, "Municipal Securities"). This investment
                      policy is a fundamental policy of the Portfolio. At least
                      65% of the Portfolio's total assets will be invested in
                      Municipal Securities which are exempt from Kansas state
                      income taxes. The remainder of the Portfolio may be
                      invested in Municipal Securities of other states. Under
                      normal conditions, the Portfolio will also invest at least
                      80% of its net assets in securities the income from which
                      is not subject to the federal alternative minimum tax.
                      Although it has no present intention of doing so, the
                      Portfolio may invest up to 20% of its assets in taxable
                      securities for defensive purposes or when sufficient tax
                      exempt securities considered appropriate by INTRUST, N.A.,
                      the Portfolio's investment adviser (the "Adviser"), are
                      not available for purchase.
                             The Portfolio will maintain a dollar-weighted
                      average portfolio maturity of seven years to twelve years.
                      However, when the Adviser determines that the market
                      conditions so warrant, the Portfolio can maintain an
                      average weighted maturity of less than seven years.
                             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
                      Adviser: (i) municipal bonds rated A or better by Standard
                      and Poor's Corporation ("S&P") or Moody's Investors
                      Service, Inc. ("Moody's"), and a maximum of 10% of the
                      Portfolio's total assets in municipal bonds rated BBB by
                      S&P or Baa by Moody's; (ii) municipal notes rated at least
                      SP-2 by S&P or MIG-2 or V-MIG-2 by Moody's; and (iii)
                      tax-exempt commercial paper rated at least A-1 by S&P or
                      Prime-1 by Moody's. Municipal notes rated SP-2 by S&P have
                      satisfactory capacity to pay principal and interest;
 
                                        4                                      +
<PAGE>   168
 
notes rated MIG-2 or VMIG-2 by Moody's are considered to be of high quality.
Bonds rated BBB by S&P have an adequate capacity to pay interest and repay
principal; bonds rated Baa by Moody's are considered to be medium-grade
obligations (i.e., neither highly protected nor poorly secured) and have
speculative characteristics.
                             For a description of the permitted investments and
                      ratings, see the "Description of Permitted Investments and
                      Risk Factors" and the Statement of Additional Information.
 
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 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. The Portfolio will not invest more than 10% of
                      its total assets in securities which are considered to be
                      illiquid.
                             The taxable 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; certificates
                      of deposit, bankers acceptances and time deposits 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 the
                      foregoing obligations.
 
Kansas Risk Factors   Under normal conditions, the Portfolio will be primarily
                      invested in municipal obligations which produce income
                      which is exempt from federal and Kansas state income
                      taxes. Accordingly, the Portfolio will have considerable
                      investments in Kansas municipal obligations, and will be
                      more susceptible to factors which adversely affect issuers
                      of Kansas obligations than a mutual fund which does not
                      have as great a concentration in the municipal obligations
                      of one particular state. Such factors include the
                      financial difficulties of Kansas, its counties,
                      municipalities and school districts, if any. See "Special
                      Considerations Relating to Kansas Municipal Securities" in

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 securities of any issuer (except the
                         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 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 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, 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 .15% of the average daily net assets of the
                      Portfolio. For the fiscal year ended August 31, 1996, the
                      Portfolio paid management fees, after waivers, of .15% of
                      its average daily net assets.
 
THE ADVISER
 
                      INTRUST Bank, N.A. in Wichita, formerly First National
                      Bank in Wichita (the "Adviser"), serves as the Portfolio's
                      investment adviser under an advisory agreement
 
                                        6                                      +

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 majority-owned subsidiary of
                      INTRUST Financial Corporation (formerly First Bancorp of
                      Kansas), a bank holding company. The Adviser is a national
                      banking association which provides a full range of banking
                      and trust services to clients. As of September 30, 1996,
                      total assets under management were approximately $1.2
                      billion. The principal place of business address of the
                      Adviser is 105 North Main Street, Box One, Wichita, Kansas
                      67201.
                             Michael Colgan, Vice President and Trust Investment
                      Officer for the Adviser since 1985, has managed the
                      portfolio of the Kansas Tax Free Income Portfolio since
                      December 1990.
                             The Adviser is entitled to a fee, which is
                      calculated daily and paid monthly, at an annual rate of
                      .30% of the average daily net assets of the Portfolio. The
                      Adviser may waive its fee, in its discretion, for
                      competitive purposes. In addition, the Adviser has
                      voluntarily agreed to waive a portion of its fee to limit
                      the total operating expenses to not more than .21% of the
                      average daily net assets for Class A and no more than .51%
                      of the average daily net assets for Class B on an
                      annualized basis. The Adviser reserves the right, in its
                      sole discretion, to terminate this voluntary fee waiver at
                      any time. For the fiscal year ended August 31, 1996, the
                      Portfolio paid advisory fees, after waivers, of .00% of
                      its relative net assets.
 
DISTRIBUTION
AND SHAREHOLDER
SERVICING
 
                      SEI Financial Services Company (the "Distributor"), a
                      wholly owned subsidiary of SEI Investments Company
                      ("SEI"), 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 and B 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 Portfolio will pay the
                      Distributor 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 Portfolio will pay
                      shareholder service fees to the Distributor 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 plan, Class
                      B shares will pay administrative services fees of up to
                      .05% of the average daily net assets of the 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 the Portfolio and thus receive
                      compensation with respect to different classes. These
                      financial institutions may also charge separate fees to
                      their customers. Certain financial institutions offering
                      shares to their customers may be required to register as
                      dealers pursuant to state laws.
                             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 in its sole
                      discretion, institute one or more promotional incentive
                      programs, which will be paid by the Distributor from its
                      own resources. Under any such program, the Distributor
                      will provide promotional incentives, in the form of cash
                      or other compensation, including merchandise, airline
                      vouchers, trips and vacation packages, to all dealers
                      selling shares of the Portfolios. Such promotional
                      incentives will be offered uniformly to all dealers and
                      predicated upon the amount of shares of the Portfolio sold
                      by the dealer.
 
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. Institutions that use certain SEI
                      proprietary systems may place orders electronically
                      through those systems. State securities laws may require
                      banks and financial institutions purchasing shares for
                      their customers to register as dealers pursuant to state
                      laws. 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 are offered only to
residents of states in which the shares are eligible for purchase.
                             Shares of the Portfolio may be purchased or
                      redeemed on days on which the New York Stock Exchange is
                      open for business ("Business Day"). 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 close of trading on the New
                      York Stock Exchange (presently 4:00 p.m. Eastern time) 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 on the next
                      Business Day following the date 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 liability, 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. 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 shareholder
                      servicing fees charged to each class.
                             The market value of each security is 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 of the pricing service and its valuation
                      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 most recently quoted bid price 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 the
                      close of trading on the New York Stock Exchange (presently
                      4:00 p.m. Eastern time) 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,
                      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 an 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. 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 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 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
 
                                       10                                      +

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.
                             The performance of Class A shares will normally be
                      higher than that of Class B shares because of the
                      additional administrative services expenses charged to
                      Class B 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.
 
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 ("RICs") 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
 
                                       11                                      +

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 RICs.
                             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. 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.
 
State Taxes           The following is a general, abbreviated summary of certain
                      of the provisions of the Kansas tax code presently in
                      effect as they directly govern the taxation of
                      shareholders subject to Kansas personal income tax. These
                      provisions are subject to change by legislative or
                      administrative action, and any such change may be
                      retroactive.
                             Under Kansas law, interest on all obligations
                      issued by the State of Kansas or its political
                      subdivisions after December 31, 1987 is excluded from
                      Kansas adjusted gross income in determining Kansas tax
                      liability, and interest from obligations issued prior to
                      January 1, 1988, is exempt from Kansas income tax only if
                      there is statutory authority exempting the interest from
                      the particular obligations in question. For Kansas income
                      tax purposes, interest on the above-described
 
                                       12                                      +

residents.
 
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: Intermediate-Term
                      Municipal Portfolio, Tax Free Portfolio, Institutional Tax
                      Free Portfolio, California Tax Exempt 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 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, 680 E. Swedesford Road, Wayne,

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.
                             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.
                             The dividends on Class A shares are normally higher
                      than on Class B shares of the Portfolio because of the
                      additional administrative services expenses charged to
                      Class B 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

                      behalf of public authorities to obtain funds to provide

                             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 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, including,
                      among others, the Federal Farm Credit Bank, the Federal
                      Housing Administration and the Small Business
                      Administration, and obligations issued or guaranteed by
                      instrumentalities of the U.S. Government, including, among
                      others, the Federal Home Loan Mortgage Corporation, the
                      Federal Land Banks and the U.S. Post Service. 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., Federal National Mortgage
 
                                       15                                      +

Association securities). Guarantees of principal by agencies or
instrumentalities of the U.S. Government may be a guarantee of payment at the
maturity of the obligation so that in the event of a default prior to maturity
there might not be a market and thus no means of realizing on the obligation
prior to maturity. Guarantees as to the timely payment of principal and interest
do not extend to the value or yield of these securities not to the value of the
Fund's shares.
 
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, high grade debt
                      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.

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
 
                                        3                                      +

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.
                             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
 
New York 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
                      (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. Both the
                      State and the City are experiencing significant 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.
                      These may have the effect of impairing the ability of the
                      issuers of New York municipal securities to pay interest
                      on, or repay the principal of, such securities. A more
                      complete description of these risks is contained in the
                      Statement of Additional Information.
 
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 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.
                      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, 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 .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. serves as the Portfolio's
                      investment adviser under an advisory agreement with 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.

Adviser is One New York Plaza, New York, NY 10004.
                             S. Blake Miller, CFA, and Nancy J. Neiman act as
                      the portfolio managers for the Portfolio. Mr. Miller, an

                      Tax Exempt Fixed Income group since 1988, and its
                      predecessor since 1986. Ms. Neiman, an Associate Principal

                             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, 1996, the Portfolio had not commenced
                      operations.
 
DISTRIBUTION
AND SHAREHOLDER
SERVICING
 
                      SEI Financial Services Company (the "Distributor"), a
                      wholly-owned subsidiary of SEI Investments Company
                      ("SEI"), 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 a
                      shareholder servicing fee of up to .25% of average daily
                      net assets attributable to Class A shares will be paid to
                      the Distributor. 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.
                             In addition, the Distributor may, from time to time
                      in its sole discretion, institute one or more promotional
                      incentive programs, which will be paid by the Distributor
                      from its own resources. Under any such program, the
                      Distributor will provide promotional incentives, in the
                      form of cash or other compensation, including merchandise,
                      airline vouchers, trips and vacation packages, to all
                      dealers selling shares of the Portfolio. Such promotional
                      incentives will be offered uniformly to all dealers and
                      predicated upon the amount of shares of the Portfolio sold
                      by the dealer.
 
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. Institutions that use certain SEI
                      proprietary systems may place orders electronically
                      through those systems. State securities laws may require
                      banks and financial institutions purchasing shares for
                      their customers to register as dealers pursuant to state
                      laws. 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 are offered only to residents of states
                      in which the shares are eligible for purchase.
                             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 close of trading on the New
                      York Stock Exchange (presently 4:00 p.m. Eastern time) 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 on the next
                      Business Day following the date 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 liability, 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.
                             The market value of each security is 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 of the pricing service and its valuation
                      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 most recent quoted bid price 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 the
                      close of trading on the New York Stock Exchange (presently
                      4:00 p.m. Eastern time) 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.

                             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 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.
                             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.
                             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. Furthermore, the Portfolio may not be an
                      appropriate investment for persons (including corporations
                      and other business entities) who are "substantial

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.
 
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.
                             Exempt-interest 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 or any territory or
                      possession of the United States 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.
                             Shareholders should consult their tax advisers
                      concerning the state and local tax consequences of
                      investment in the Portfolio, which may differ from the
                      federal income tax consequences described above.
 
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, Kansas Tax
                      Free Income 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
 
                                       12                                      +

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.

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.
                             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 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 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, including,
                      among others, the Federal Farm Credit Bank, the Federal
                      Housing Administration and the Small Business
                      Administration, and obligations issued or guaranteed by
                      instrumentalities of the U.S. Government, including, among
                      others, the Federal Home Loan Mortgage Corporation, the
                      Federal Land Banks and the U.S. Post Service. 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., Federal National Mortgage Association securities).
                      Guarantees of principal by agencies or instrumentalities
                      of the U.S. Government may be a guarantee of payment at
                      the maturity of the obligation so that in the event of a
                      default prior to maturity there might not be a market and
                      thus no means of realizing on the obligation prior to
                      maturity. Guarantees as to the timely payment of principal
                      and interest do not extend to the value or yield of these
                      securities not to the value of the Fund's shares.
 
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, high grade debt
                      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.

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, Kansas Tax Free Income 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 Class G 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

ALL PORTFOLIOS

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 the
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 the 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 the 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").

                                       S-2
<PAGE>   204
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 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. The Portfolio or its agent will have actual or constructive possession
of the securities held as collateral for the repurchase agreement. The 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 the 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-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, the issuer, or a third party (the "writer") at an

                                       S-3
<PAGE>   205
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, Pennsylvania Municipal
and Kansas Tax Free Income 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. 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-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, high grade 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. 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.

                                       S-5
<PAGE>   207
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, Pennsylvania Tax Free
      and Kansas Tax Free Income 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 any 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.

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.

                                       S-6
<PAGE>   208
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, the Kansas Tax
      Free Income 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 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 Kansas Tax Free Income Portfolio and New York
Intermediate-Term Municipal Portfolio and 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.

                                       S-7
<PAGE>   209
AMENDMENTS TO THE CALIFORNIA CONSTITUTION AND RELATED STATUTES. Certain of the
California Municipal Securities may be obligations of issuers who rely in whole
or in part on ad valorem real property taxes as a source of revenue. On June 6,
1978, California voters approved an amendment to the California Constitution
known as Proposition 13, which added Article XIIIA to the California
Constitution. The effect of Article XIIIA is to limit ad valorem taxes on real
property, and to restrict the ability of taxing entities to increase real
property tax revenues. On November 7, 1978, California voters approved
Proposition 8, and on June 3, 1986, California voters approved Proposition 46,
both of which amended Article XIIIA. Article XIIIA may require further
interpretation by both the Legislature and the courts to determine its
applicability to specific situations involving the State and local taxing
authorities.

OTHER RELEVANT CALIFORNIA LAWS. A wide variety of California laws and
regulations may affect, directly or indirectly, the payment of interest on, or
the repayment of the principal of, California Municipal Securities in which the
Portfolio may invest. The impact of such laws and regulations on particular
California Municipal Securities may vary depending upon numerous factors
including, among others, the particular type of Municipal Security involved, the
public purpose funded by the Municipal Security and the nature and extent of
insurance or other security for payment of principal and interest on the
Municipal Security. For example, California Municipal Securities which are
payable only from the revenues derived from a particular facility may be
adversely affected by California laws or regulations which make it more
difficult for the particular facility to generate revenues sufficient to pay
such interest and principal, including, among others, laws and regulations which
limit the amount of fees, rates or other charges which may be imposed for use of
the facility or which increase competition among facilities of that type or
which limit or otherwise have the effect of reducing the use of such facilities
generally, thereby reducing the revenues generated by the particular facility.
California Municipal Securities, the payment of interest and principal on which
is insured in whole or in part by a California governmentally created fund, may
be adversely affected by California laws or regulations which restrict the
aggregate insurance proceeds available for payment of principal and interest in
the event of a default on such Municipal Securities.

THE GENERAL FINANCIAL CONDITION OF THE STATE OF CALIFORNIA. Since the start of
the 1990-91 Fiscal Year, the State has faced the worst economic, fiscal, and
budget conditions since the 1930s. Construction, manufacturing (especially
aerospace), exports and financial services, among others, have all been severely
affected.

The recession has seriously affected State tax revenues, which basically mirror
economic conditions. It also caused increased expenditures for health and
welfare programs. The State has been facing a structural imbalance in its budget
with the largest programs supported by the General Fund - K-12 schools and
community colleges, health and welfare, and corrections - growing at rates
significantly higher than the growth rates for the principal revenue sources of
the General Fund. As a result, the State has experienced recurring budget
deficits.

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 KANSAS MUNICIPAL SECURITIES

STATE DEBT. The State does not issue general obligation debt but has issued
certificates of participation which are subject to annual legislative
appropriation. The State has also issued revenue bonds for the Highway and
Turnpike systems, for various Regents system higher education facilities and for
various state agency projects.

LOCAL GOVERNMENT DEBT. Local government in Kansas consists of numerous
individual units. Each unit is distinct and independent of other local units,
although they may overlap geographically. These various local governmental units
are empowered by statute to issue general obligation and/or revenue supported
debt. The degree to which

                                       S-8
<PAGE>   210
overlapping debt exists will vary considerably across the state and is a factor
in evaluating the risk involved in a given bond issue. Debt can be levied by
counties, cities or townships, schools and districts (e.g., fire, sewer, rural
water, drainage, etc.). The county treasurer is authorized to collect for and
remit to the various issuers in the county the tax receipts due.

TAX LAW CHANGES. The State Legislature passed a statute that made all Kansas
bond issues dated after December 31, 1987 exempt from Kansas income taxes. Prior
to the passage of that statute only certain issues, primarily state and
industrial development revenue bonds were exempt from Kansas income tax. This
change in the law has made the Kansas municipal bond market more homogenous and
deeper rather than segmented by tax status, as was the case previously. The
change has increased the number and amount of high quality, rated issues
available in the Kansas income tax-exempt market. The Legislature could change
the situation by reverting to a narrower base of Kansas income tax-exempt
issues, perhaps in response to budgetary constraints. This would make it more
difficult for the Kansas Tax Free Income Portfolio to invest in Kansas income
tax-exempt issues and would likely decrease the yield on the Portfolio's
subsequent purchases.

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. These grants include disbursements for elementary,
secondary and higher education, social services, drug abuse control, and mass
transportation programs.

STATE DEBT. Under the State Constitution, the State may not, with limited
exceptions for emergencies, undertake long term borrowing (i.e., borrowing for
more than one year) unless the borrowing is authorized in a specific amount for
a single work or purpose by the Legislature and approved by the voters. There is
no limitation on the amount of long term debt that may be so authorized and
subsequently incurred by the State. The State may undertake short term
borrowings without voter approval (i) in the anticipation of the receipt of
taxes and revenues, by issuing tax and revenue anticipation notes, and (ii) in
anticipation of the receipt of proceeds from the sale of duly authorized but
unissued bonds, by issuing bond anticipation notes. The State Constitution
provides that the State may guarantee the repayment of certain borrowings to
carry out designated projects by the New York State Thruway Authority, the Job
Development Authority and the Port Authority of New York and New Jersey.

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 and
continues to require significant financial assistance from the State.

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. Revenues not required
to be deposited in another fund are deposited in the General Fund.
Pennsylvania's major expenditures include funding for education and public
health and human services.

COMMONWEALTH DEBT. Current constitutional provisions permit Pennsylvania to
issue the following types of debt: (i) debt to suppress insurrection or
rehabilitate areas affected by disaster, (ii) electorate approved debt, (iii)
debt for capital projects subject to an aggregate debt limit of 1.75 times the
annual average tax revenues of the preceding

                                       S-9
<PAGE>   211
five fiscal years and (iv) tax anticipation notes payable in the fiscal year of
issuance. All debt except tax anticipation notes must be amortized in
substantial and regular amounts.

Pennsylvania engages in short-term borrowing to fund expenses within a fiscal
year through the sale of tax anticipation notes which must mature within the
fiscal year of issuance. The principal amount issued, when added to that already
outstanding, may not exceed in the aggregate 20% of the revenues estimated to
accrue to the appropriate fund in the fiscal year. The Commonwealth is not
permitted to fund deficits between fiscal years with any form of debt. All
year-end deficit balances must be funded within the succeeding fiscal year's
budget. Pending the issuance of bonds, Pennsylvania may issue bond anticipation
notes subject to the applicable statutory and constitutional limitations
generally imposed on bonds. The term of such borrowings may not exceed three
years. The Commonwealth currently has no bond anticipation notes outstanding.

STATE-RELATED OBLIGATIONS. Certain state-created agencies have statutory
authorization to incur debt for which legislation providing for state
appropriations to pay debt service thereon is not required. The debt of these
agencies is supported by assets of, or revenues derived from, the various
projects financed and the debt of such agencies is not an obligation of
Pennsylvania although some of the agencies are indirectly dependent on
Commonwealth appropriations.

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. An authority is organized by a municipality acting singly or
jointly with another municipality and is governed by a Board appointed by the
governing unit of the creating municipality or municipalities. Typically,
authorities are established to acquire, own and lease or operate one or more
projects and to borrow money and issue revenue bonds to finance them.

THE MANAGER

The Management Agreement provides that SEI Fund Management (the "Manager") shall
not be liable for any error of judgment 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.

The Manager, a Delaware business trust, has its principal business offices at
Oaks, Pennsylvania 19452. SEI Financial Management Corporation ("SFM"), a
wholly-owned subsidiary of SEI Investments Company ("SEI"), is the owner of all
beneficial interest in the Manager. SEI and its subsidiaries, including the
Manager, are leading providers of funds evaluation services, trust accounting
systems, and brokerage and information services to financial institutions,
institutional investors and money managers. The Manager and its affiliates also
serve as administrator to the following other mutual funds: The Achievement
Funds Trust; The Advisors' Inner Circle Fund; The Arbor Fund; ARK Funds; Bishop
Street Funds; CoreFunds, Inc.; CrestFunds, Inc.; CUFUND; FMB Funds, Inc.; First

DISTRIBUTION AND SHAREHOLDER SERVICING

The Trust has adopted Distribution Plans for Class D and Class G 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-12
<PAGE>   214
The Plans provide that the Trust will pay the Distributor a fee on the Class D
and Class G 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 Class G 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, 1996, 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

                                      S-17
<PAGE>   219
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,
Kansas Tax Free Income 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)]degree symbol - 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.

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, 1996, the end of the Trust's most recent
fiscal year, the money market Portfolios' current effective and tax-equivalent
yields were as follows:

*Not in operation during the period.

From time to time, the Intermediate-Term Municipal, Pennsylvania Municipal,
Kansas Tax Free Income 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.

Based on the foregoing, the average annual total returns for the Portfolios from
inception through August 31, 1996 and for the one, five and ten year periods
ended August 31, 1996 were as follows:

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

                                      S-20
<PAGE>   222
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 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, Kansas
Tax Free Income and New York Intermediate-Term Municipal Portfolios are 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

                                      S-21
<PAGE>   223
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.

In calculating the sales charge rates applicable to current purchases of Class D
shares, members of the following affinity groups and clients of the following
broker-dealers, each of which has entered into an agreement with the
Distributor, are entitled to the following percentage-based discounts from the
otherwise applicable sales charge:

SHAREHOLDER SERVICES

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.

The following is a description of plans and privileges by which the sales
charges imposed on the Class D shares of the Tax Free Portfolio may be reduced.

RIGHT OF ACCUMULATION: A shareholder qualifies for cumulative quantity discounts
when his new investment, together with the current market value of all holdings
of that shareholder in the Portfolios reaches a discount level. See "Additional
Information About Doing Business With Us" in the Prospectuses for the sales
charge on quantity purchases.

LETTER OF INTENT: The reduced sales charges are also applicable to the aggregate
amount of purchases made by any such purchaser previously enumerated within a
13-month period pursuant to a written Letter of Intent provided by the
Distributor, and not legally binding on the signer or a Portfolio which provides
for the holding in escrow by the Distributor of 5% of the total amount intended
to be purchased until such purchase is completed within the 13-month period. A
Letter of Intent may be dated to include shares purchased up to 90 days prior to
the date the Letter of Intent is signed. The 13-month period begins on the date
of the earliest purchase. If the intended investment is not completed, the
Manager will surrender an appropriate number of the escrowed shares for
redemption in order to realize the difference.

DISTRIBUTION INVESTMENT OPTION: Distributions of dividends and capital gains
made by the Portfolios may be automatically invested in shares of one of the
Portfolios if shares of the Portfolio are available for sale. Such investments
will be subject to initial investment minimums, as well as additional purchase
minimums. A shareholder considering the Distribution Investment Option should
obtain and read the prospectus of the other Portfolios and consider the
differences in objectives and policies before making any investment.

                                      S-22
<PAGE>   224
REINSTATEMENT PRIVILEGE: A shareholder who has redeemed shares of any of the
Portfolios has a one-time right to reinvest the redemption proceeds in shares of
the Portfolios at their net asset value as of the time of reinvestment. Such a
reinvestment must be made within 30 days of the redemption and is limited to the
amount of the redemption proceeds. Although redemptions and repurchases of
shares are taxable events, a reinvestment within such 30-day period in the same
fund is considered a "wash sale" and results in the inability to recognize
currently all or a portion of a loss realized on the original redemption for
federal income tax purposes. The investor must notify the Transfer Agent at the
time the trade is placed that the transaction is a reinvestment.

EXCHANGE PRIVILEGE: A shareholder may exchange the shares of these Portfolios,
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.

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.

                                      S-23
<PAGE>   225
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 alterna
tive 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 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"

                                      S-24
<PAGE>   226
(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. 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 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 year ended August 31, 1996 the Portfolios paid brokerage fees as
follows:

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, 1995 and 1996, 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 Class G 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.

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

                                      S-28
<PAGE>   230
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 6, 1996, 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.
