portfolios of securities. Some portfolios offer separate classes of units of
beneficial interest that differ from each other primarily in the allocation of
certain distribution expenses and minimum investment amounts. This Prospectus

a "Portfolio" and, together, the "Portfolios") listed above.
 
AN INVESTMENT IN A PORTFOLIO IS NEITHER INSURED NOR GUARANTEED BY THE U.S.
GOVERNMENT, AND THERE CAN BE NO ASSURANCE THAT A PORTFOLIO WILL BE ABLE TO
MAINTAIN A STABLE NET ASSET VALUE OF $1.00 PER SHARE.

EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION, NOR HAS THE SECURITIES

(1) The Manager has agreed to waive its fee in an amount necessary to limit the
    total operating expenses of each Portfolio to not more than .44% of its
    average net assets. In the case of the Institutional Cash Portfolio, this
    waiver is voluntary and may be terminated at any time in the Manager's sole
    discretion. Absent this waiver, management/advisory fees for the Treasury
    Securities, Government Securities, Prime Obligation and Money Market
    Portfolios, would be .45%, .45%, .45%, and .45%, respectively.
    Management/Advisory fees have been restated to reflect reductions in fee
    waivers.
(2) Total Other Expenses for the Money Market Portfolio are based on estimated
    amounts for the current fiscal year.
(3) The Distributor has waived, on a voluntary basis, all or a portion of its
    shareholder servicing fee, and the Shareholder Servicing Expenses shown
    reflect this waiver. The Distributor reserves the right to terminate its
    waiver at any time in its sole discretion. Absent such waiver, Shareholder
    Servicing Expenses would be .25% for each of the Portfolios.
(4) Absent waivers, Total Operating Expenses for the Treasury Securities,
    Government Securities, Prime Obligation, Institutional Cash and Money Market
    Portfolios would be .75%, .75%, .75%, .69%, and .75%, respectively.
    Additional information may be found under "The Manager," "The Adviser" and

THE EXAMPLE SHOULD NOT BE CONSIDERED A REPRESENTATION OF 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 Class A shares of the Portfolios. The Treasury Securities
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," "The Adviser" and "Distribution
and Shareholder Servicing".

                      obligations and obligations issued or guaranteed as to
                      principal and interest by the agencies or
                      instrumentalities of the U.S. Government; (vi) U.S. dollar
                      denominated obligations of foreign governments, including
                      Canadian and Provincial Government and Crown Agency
                      obligations; (vii) repurchase agreements involving any of
                      the foregoing obligations; and (viii) custodial receipts
                      representing investments in component parts of U.S.
                      Treasury obligations.
                             There can be no assurance that the Portfolios will
                      achieve their respective investment objectives.

GENERAL
INVESTMENT
POLICIES
 
                      In purchasing obligations, each Portfolio complies with
                      the requirements of Rule 2a-7 under the 1940 Act, as that
                      Rule may be amended from time to time. These requirements
                      currently provide that each 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, each 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 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. Purchases of unrated securities will
                      be ratified by the Trust's Board of Trustees.
                             Securities rated in the highest rating category
                      (e.g., A-1 by S&P) by at least two NRSROs (or by one NRSRO
                      if only one NRSRO has rated the security, or, if unrated,
                      determined by the Adviser to be of comparable quality) are
                      "first tier" securities. 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. Each Portfolio will invest, in the aggregate,
                      no more than 5% of its assets in second tier securities,
                      and any investment in any one second tier security is
                      limited to the greater of 1% of a Portfolio's total assets
                      or $1 million.
                             The quality, maturity and diversification
                      requirements of the Government Securities and Prime
                      Obligation Portfolios are more restrictive than those
                      imposed by Rule 2a-7. The Government Securities and Prime
                      Obligation Portfolios may only purchase securities with a
                      remaining maturity of 365 days or less, and, as a matter
                      of non-fundamental policy, will maintain a dollar-weighted
                      average portfolio maturity of 90 days or less. If
                      Shareholders of these Portfolios elect to modify the
                      Portfolios' investment limitations in the future, the
                      Portfolios could take advantage of certain provisions in
                      the Rule that are more liberal than the Portfolios'
                      policies and that are followed by the Trust's other
                      Portfolios.
                             The Money Market and Prime Obligation Portfolios
                      may invest up to 10% of their net assets in illiquid
                      securities. However, restricted securities, including Rule
                      144A securities and Section 4(2) commercial paper, that
                      meet the criteria established by the Board of Trustees of
                      the Trust will be considered liquid.

                             Each Portfolio may purchase securities on a
                      when-issued or delayed delivery basis.
                             For additional information regarding the
                      Portfolios' permitted investments and the ratings referred

                      Risk Factors" and the Statement of Additional Information.
 
INVESTMENT
LIMITATIONS
 
                      The investment objective and certain of the investment
                      limitations are fundamental policies of the Portfolios.
                      Fundamental policies cannot be changed with respect to 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 each Portfolio to use
                      its best efforts to maintain a constant net asset value of
                      $1.00 per share. In addition, it is a fundamental policy
                      of each of the Government Securities and Prime Obligation
                      Portfolios to invest its assets solely in the securities
                      listed as appropriate investments for that Portfolio.
 
                      Each Portfolio may not:
                      1. Purchase securities of any issuer (except securities
                         issued or guaranteed by the U.S. Government, its
                         agencies or instrumentalities and any securities
                         guaranteed thereby) if as a result more than 5% of the
                         total assets of the Portfolio (based on fair market
                         value at the time of investment) would be invested in
                         the securities of such issuer; provided, however, that
                         the Treasury Securities, Money Market and Institutional
                         Cash Portfolios may temporarily invest up to 25% of
                         their 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 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 (a) domestic banks and (b) 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 that Portfolio. This
                         borrowing provision is included solely to facilitate
                         the orderly sale of portfolio securities to accommodate
                         substantial redemption requests if they should occur
                         and is not for investment purposes. All borrowings will
                         be repaid before making additional investments for that
                         Portfolio and any interest paid on such borrowings will
                         reduce the income of that 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 ("SEI Management"), provides the Trust
                      with overall management services, regulatory reporting,
                      all necessary office space, equipment, personnel and
                      facilities, and acts as dividend disbursing agent and
                      shareholder servicing agent. SEI Management also serves as
                      transfer agent (the "Transfer Agent") to certain classes
                      of the Trust.
                             For its management services, SEI Management is
                      entitled to a fee, which is calculated daily and paid
                      monthly, at an annual rate of .42% of the average daily
                      net assets of each Portfolio, except the Institutional
                      Cash Portfolio, for which SEI Management is entitled to a
                      fee of .36% of the Portfolio's average daily net assets.
                      SEI Management has contractually agreed to waive all or a
                      portion of its fee with respect to each Portfolio, except
                      the Institutional Cash Portfolio, in order to limit the
                      total operating expenses of the Class A shares of such
                      Portfolios to not more than .44% of its average daily net
                      assets. For the Institutional Cash Portfolio only, this
                      waiver is voluntary and may be terminated at any time in
                      SEI Management's sole discretion.
                             For the fiscal year ended June 30, 1996, the
                      Treasury Securities, Government Securities, Prime
                      Obligation, and Institutional Cash Portfolios paid
                      management fees, after waivers, of .33%, .33%, .33% and
                      .36%, respectively, of their average daily net assets. As
                      of June 30, 1996, the Money Market Portfolio had not
                      commenced operations.
 
THE ADVISER
 
                      Wellington Management Company, LLP (the "Adviser"), 75
                      State Street, Boston, Massachusetts 02109, serves as the
                      investment adviser to each Portfolio. The Adviser, under
                      an investment advisory agreement with the Trust, invests
                      the assets of the Portfolios and continuously reviews,
                      supervises and administers each Portfolio's investment
                      program, subject to the supervision of, and policies
                      established by, the Trustees of the Trust.
                             As of September 30, 1996, the Adviser had
                      investment management authority with respect to
                      approximately $123.8 billion of assets, including the
                      assets of the Trust and SEI Daily Income Trust, which is
                      an open-end management investment company administered by
                      the Manager. The Adviser is a professional investment

                      investment companies, employee benefit plans, endowments,
                      foundations, and other institutions and individuals. The
                      Adviser's predecessor organizations have provided
                      investment advisory services to investment companies since
                      1933, and to investment counseling clients since 1960. The
                      Adviser is a Massachusetts limited liability partnership,
                      of which the following persons are managing partners:

                             The Adviser is entitled to a fee, which is
                      calculated daily and paid monthly, at an annual rate of
                      .075% of the combined average daily net assets of the
                      Trust's Portfolios up to $500 million, and .02% of such
                      average daily net assets in excess of $500 million. Such
                      fees are allocated daily among the Portfolios of the Trust
                      on the basis of their relative net assets. For the fiscal
                      year ended June 30, 1996, the Treasury Securities,
                      Government Securities, Prime Obligation, and Institutional
                      Cash Portfolios paid advisory fees, after fee waivers, of
                      .03%, .03%, .03%, and .00%, respectively, of their
                      relative net assets. As of June 30, 1996, the Money Market
                      Portfolio had not commenced operations.
 
DISTRIBUTION
AND SHAREHOLDER
SERVICING
 
                      SEI Financial Services Company (the "Distributor"), a
                      wholly-owned subsidiary of SEI Corporation, serves as each
                      Portfolio's distributor pursuant to a distribution
                      agreement with the Trust. The Portfolios have adopted a
                      shareholder service plan for their Class A shares (the
                      "Class A Plan"). The Treasury Securities Portfolio has
                      adopted a distribution plan for its Class D shares (the
                      "Class D Plan") pursuant to Rule 12b-1 under the
                      Investment Company Act of 1940, as amended (the "1940
                      Act").
                             Under the Class A Plan, 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
                      Class A 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 Class A Plan, the
                      Distributor may retain as a profit any difference between
                      the fee it receives and the amount it pays to third
                      parties. The Distributor is currently waiving all
                      shareholder servicing fees payable under the Class A Plan
                      for each Portfolio.
                             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 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 Class A shares of the
                      Portfolios 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 may
                      impose an earlier cut-off time for receipt of purchase
                      orders directed through them to allow time for processing
                      and transmittal of these orders to the Transfer Agent for
                      effectiveness on the same day. Financial institutions
                      which purchase shares for the accounts of their customers
                      may impose separate charges on these customers for account
                      services. Shares of the Portfolios 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 on which wire transfers are restricted.
                             Shareholders who desire to purchase shares must
                      place their orders with the Transfer Agent prior to 2:00
                      p.m., Eastern time (12:00 p.m., Eastern time for the
                      Institutional Cash Portfolio), 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 after
                      each purchase or redemption 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 each Portfolio is
                      determined by dividing the total market
 
                                       11
<PAGE>   12
 
                      value of the Portfolio's investments and other assets,
                      less any liabilities, by the total number of outstanding
                      shares of that Portfolio. Net asset value per share is
                      determined daily as of 2:00 p.m., Eastern time (12:00
                      p.m., Eastern time for the Institutional Cash Portfolio),
                      on each Business Day.
                             Shareholders who desire to redeem shares of a
                      Portfolio must place their redemption orders with the
                      Transfer Agent prior to 2:00 p.m., Eastern time (12:00
                      p.m., Eastern time for the Institutional Cash Portfolio),
                      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 redemptions will be made as promptly as
                      possible and, in any event, within seven days after the
                      redemption order is received.
                             Purchase and redemption orders may be placed by
                      telephone. Neither the Trust nor the Trust's 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 Trust's 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 Portfolios may advertise "current
                      yield" and "effective compound yield." These figures will
                      fluctuate, as they are based on historical earnings and
                      are not intended to indicate future performance. The
                      "current yield" of the Portfolios 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 an 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.
                             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 performance of the Class A shares will normally
                      be higher than the performance of the Class D shares of
                      the Portfolio because of 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, state, or local income tax treatment of
                      the Portfolios or their shareholders. In addition, state
                      and local tax consequences of an investment in a 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 Portfolios     Each Portfolio is treated as a separate entity for federal
                      tax purposes and is not combined with the Trust's other
                      Portfolios. Each Portfolio intends to qualify for the
                      special tax treatment afforded regulated investment
                      companies under Subchapter M of the Internal Revenue Code
                      of 1986, as amended, so as to be relieved of federal
                      income tax on net investment company taxable income and
                      net capital gains (the excess of net long-term capital
                      gain over net short-term capital losses) distributed to
                      shareholders.
 
Tax Status
of Distributions      Each Portfolio distributes substantially all of its net
                      investment income (including net short-term capital gains)
                      to shareholders. Dividends from a Portfolio's net
                      investment income are taxable to its shareholders as
                      ordinary income (whether received in cash or in additional
                      shares). Distributions of net capital gains are taxable as
                      long-term capital gains, regardless of how long
                      shareholders have held their shares and regardless of
                      whether the distributions are received in cash or in
                      additional shares. Dividends and distributions of capital
                      gains paid by each Portfolio do not qualify for the
                      dividends-received deduction for corporate shareholders.
                      Each Portfolio will provide annual reports to shareholders
                      of the federal income tax status of all distributions.
                             Dividends declared by a Portfolio in October,
                      November or December of any year and payable to
                      shareholders of record on a date in such a month will be
                      deemed to have been paid by the Portfolio and received by
                      the shareholders on December 31 of the year declared if
                      paid by the Portfolio at any time during the following
                      January.
                             Each Portfolio intends to make sufficient
                      distributions prior to the end of each calendar year to
                      avoid liability for the federal excise tax applicable to
                      regulated investment companies.

                             With respect to investments in U.S. Treasury
                      STRIPS, which are sold at original issue discount and thus
                      do not make periodic cash interest payments, each
                      Portfolio will be required to include as part of its
                      current income, the imputed interest on such obligations
                      even though the Portfolio has not received any interest
                      payments on such obligations during that period. Because
                      each Portfolio distributes all of its net investment
                      income to its shareholders, a Portfolio may have to sell
                      portfolio securities in order to distribute such imputed
                      income, which may occur at a time when the Adviser would
                      not have chosen to sell such securities and, which may
                      result in a taxable gain or loss.
                             Investment income received by the Portfolios on
                      direct U.S. Government obligations is exempt from tax at
                      the state level when received directly by a Portfolio, and
                      may be exempt, depending on the state, when received by a
                      shareholder as income dividends from any Portfolio
                      provided certain state-specific conditions are satisfied.
                      Interest received on repurchase agreements collateralized
                      by U.S. Government obligations normally is not exempt from
                      state taxation. Each Portfolio will inform shareholders
                      annually of the percentage of income and distributions
                      derived from direct U.S. Government obligations.
                      Shareholders should consult their tax advisers to
                      determine whether any portion of the income dividends
                      received from a Portfolio is considered tax exempt in
                      their particular states.
                             Each sale, exchange, or redemption of any
                      Portfolio's shares is a taxable transaction to the
                      shareholder.
 
GENERAL
INFORMATION
 
The Trust             SEI Liquid Asset Trust (the "Trust") was organized as a
                      Massachusetts business trust under a Declaration of Trust
                      dated July 20, 1981. The Declaration of Trust permits the
                      Trust to offer separate Portfolios of shares and different
                      classes of each Portfolio. All consideration received by
                      the Trust for shares of any portfolio and all assets of
                      such portfolio belong to that portfolio or class and are
                      subject to liabilities related thereto.
                             The Trust pays its expenses, including fees of its
                      service providers, audit and legal expenses, expenses of
                      preparing prospectuses, proxy solicitation material and
                      reports to shareholders, costs of custodial services and
                      registering the shares under federal and state securities
                      laws, pricing, insurance expenses, litigation and other
                      extraordinary expenses, brokerage costs, interest charges,
                      taxes and organization expenses.
 
Trustees of the Trust The management and affairs of the Trust are supervised by
                      the Trustees under the laws of the Commonwealth of
                      Massachusetts. The Trustees have approved contracts under
                      which, as described above, certain companies provide
                      essential management services to the Trust.

Voting Rights         Each share held entitles the shareholder of record to one
                      vote. The shareholders of each Portfolio or class of the
                      Trust will vote separately on matters relating solely to
                      that Portfolio or class. 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.
                             As of August 1, 1996, Vose & Co. and Repub & Co.
                      owned a controlling interest (as defined by the Investment
                      Company Act of 1940) in the Trust's Government Securities
                      Portfolio.
 
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 each Portfolio is periodically
                      declared and paid as a dividend. 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 (the excess of net
                      long-term capital gain over net short-term capital loss)
                      realized, if any, are distributed at least annually.

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:
 
Bank Notes            Bank notes are notes used to represent debt obligations
                      issued by banks in large denominations.
 
Bankers' Acceptance   A bankers' acceptance is a bill of exchange or time drafts
                      drawn on and accepted by a commercial bank. It is used by
                      corporations to finance the shipment and storage of goods
                      and to furnish dollar exchange. Maturities are generally
                      six months or less.
 
Certificates of 
  Deposit             Certificates of deposit are negotiable interest-bearing
                      instruments 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 have penalties for early withdrawal.
 
Commercial Paper      Commercial paper is the term used to designate unsecured
                      short-term promissory notes issued by municipalities,
                      corporations and other entities. Maturities on these
                      issues vary from one to 270 days. Section 4(2) commercial
                      paper is issued in reliance on an exemption from
                      registration under Section 4(2) of the Securities Act of
                      1933 (the "1933 Act"), and is generally sold to
                      institutional investors who purchase for investment. Any
                      resale of such commercial paper must be in an exempt
                      transaction, usually to an institutional investor through
                      the issuer or investment dealers who make a market in such
                      commercial paper.
 
Demand Instruments    Demand instruments are instruments which may involve a
                      conditional or unconditional demand feature which permits
                      the holder to demand payment of the principal amount of
                      the instrument. They may include variable amount master
                      demand notes.
 
Foreign Securities    The Money Market Portfolio may invest in U.S. dollar
                      denominated obligations of issuers domiciled outside of
                      the United States ("Yankees"), securities issued by
                      foreign branches of U.S. commercial banks and of U.S. and
                      London branches of foreign banks, and obligations and
                      securities of foreign governments, including Canadian and
                      Provincial Government and Crown Agency obligations.
                      Investments in such instruments involve risks that are
                      different from investments in securities of U.S. banks.
                      These risks may include future unfavorable political and
                      economic developments, possible withholding taxes, seizure
                      of foreign deposits, currency controls, interest
                      limitations or other governmental restrictions which might
                      affect payment of principal or interest. Foreign branches
                      of foreign banks are not regulated by U.S. banking
                      authorities and generally are not bound by accounting,
 
                                       16

                      auditing and financial reporting standards comparable
                      to U.S. banks. Additionally, there may be less public
                      information available about foreign banks and their
                      branches. However, the Adviser attempts to minimize these
                      risks by investing only in those instruments which
                      satisfy the quality and maturity restrictions applicable
                      to the Portfolio.
 
Illiquid Securities   Illiquid securities are securities which cannot be sold or
                      disposed of within seven business days at approximately
                      the value at which they are being carried on a Portfolio's
                      books. Illiquid securities may include demand instruments
                      with demand notice periods exceeding seven days for which
                      there is no secondary market, and repurchase agreements
                      with maturities over seven days in length.
 
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.
                             Municipal Securities include both municipal notes
                      and municipal bonds. 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.
                             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 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 a
                      facility's user to meet its financial obligations and the
                      pledge, if any, of real and personal property as security
                      for such payment.
                             Taxable Municipal Securities: Taxable Municipal
                      Securities are Municipal Securities the interest on which
                      is not exempt from federal income tax. Taxable Municipal
                      Securities include "private activity bonds" that are
                      issued by or on behalf of states or political subdivisions
                      thereof to finance privately-owned or operated facilities
                      for business and manufacturing, housing, sports, and
                      pollution control and to finance activities of and
                      facilities for charitable institutions. Private activity
                      bonds are also used to finance public facilities such as
                      airports, mass transit systems, ports, parking lots, and
                      low income housing. The payment of the principal and
                      interest on
 
                                       17
<PAGE>   18
 
                      private activity bonds is not backed by a pledge of tax
                      revenues, and is dependent solely on the ability of the
                      facility's user to meet its financial obligations, and
                      may be secured by a pledge of real and personal property
                      so financed. Interest on these bonds may not be exempt
                      from federal income tax.
 
Repurchase Agreements Repurchase agreements are agreements by which a Portfolio
                      obtains a security and simultaneously commits to return
                      the security to the seller at an agreed upon price on an
                      agreed upon date within a number of days from the date of
                      purchase. The Portfolio or its agent will have actual or
                      constructive possession of the securities held as
                      collateral for the repurchase agreement. Collateral must
                      be maintained at a value at least equal to 100% of the
                      resale price. A 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. A Portfolio will enter into repurchase
                      agreements only with financial institutions deemed to
                      present minimal risk of bankruptcy during the term of the
                      agreement based on established guidelines. Repurchase
                      agreements are considered loans under the 1940 Act.
 
Restricted Securities Restricted securities are securities that may not be sold
                      freely to the public absent registration under the 1933
                      Act, or an exemption from registration.
 
Time Deposits         Time deposits are non-negotiable receipts issued by a bank
                      in exchange for the deposit of funds. Similar to a
                      certificate of deposit, a time deposit earns a specified
                      rate of interest over a definite period of time; however,
                      it cannot be traded in the secondary market.
 
U.S. Government 
 Agency Obligations   Certain federal agencies, such as the Government National
                      Mortgage Association ("GNMA"), have been established as
                      instrumentalities of the U.S. Government to supervise and
                      finance certain types of activities. Issues of these
                      agencies, while not direct obligations of the U.S.
                      Government, are either backed by the full faith and credit
                      of the United States (such as GNMA securities) or
                      supported by the issuing agency's right to borrow from the
                      Treasury. The issues of other agencies are supported only
                      by the credit of the instrumentality (such as Federal
                      National Mortgage Association securities). Any guarantee
                      by the U.S. Government agencies or instrumentalities of
                      all securities in which a Portfolio invests guarantees
                      only the payment of principal and interest on the
                      guaranteed security and does not guarantee the yield or
                      value of the security or the yield or value of shares of
                      that Portfolio.
 
U.S. Treasury
Obligations           U.S. Treasury obligations consist of bills, notes and
                      bonds issued by the U.S. Treasury, as well as separately
                      traded interest and principal component parts of such
                      obligations, known as Separately Traded Registered
                      Interest and Principal Securities ("STRIPS"), that are
                      transferable through the federal book-entry system.
 
                                       18
<PAGE>   19
 
                             STRIPS are sold as zero coupon securities, which
                      means that they are sold at a substantial discount and
                      redeemed at face value at their maturity date without
                      interim payments of interest or principal. This discount
                      is accreted over the life of the security, and such
                      accretion will constitute the income earned on the
                      security for both accounting and tax purposes. Because of
                      these features, such securities may be subject to greater
                      interest rate volatility than interest-paying investments.
                      See also "Taxes."
 
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. A 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 a 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, a Portfolio may dispose of a when-issued
                      security or forward commitment prior to settlement if the
                      Adviser deems it appropriate to do so.

INVESTMENT
OBJECTIVE AND
POLICIES              The Treasury Securities Portfolio seeks to preserve
                      principal value and maintain a high degree of liquidity

(1)  A charge, currently $10.00, is imposed on wires of redemption proceeds of
     the Portfolio's Class D shares.
(2)  The Manager has agreed to waive its fee in an amount necessary to limit the
     total operating expenses for Class D shares of the Portfolio to not more
     than .84% of its average daily net assets. Absent this waiver,
     management/advisory fees, would have been .45%. The Portfolio's
     Management/Advisory fees have been restated to reflect reductions in fee
     waivers.
(3)  The Distributor has waived, on a voluntary basis, all or a portion of its
     12b-1 fee, and the 12b-1 Fees shown reflect this waiver. The Distributor
     reserves its right to terminate this waiver at any time in its sole
     discretion. Absent such waiver, 12b-1 Fees would be .25% for the Portfolio.
(4)  Absent waivers, Total Operating Expenses of the Class D shares of the
     Portfolio would be .90%. Additional information may be found under "The
     Manager and Shareholder Servicing Agent," "The Adviser" and "Distribution."

An investor in the Class D shares of the Portfolio would pay the following expenses on
  a $1,000 investment assuming (1) a 5% annual return and (2) redemption at the end of
  each time period:
    Treasury Securities Portfolio                                                          $ 8      $ 25      $ 44       $98

</TABLE>
 
THE EXAMPLE SHOULD NOT BE CONSIDERED A REPRESENTATION OF FUTURE EXPENSES. ACTUAL
EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN.
 
The information set forth in the foregoing table and example relates only to the
Class D shares. The Portfolio also offers Class A shares, which are subject to
the same expenses, except there are no transfer agent costs, and there are
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 "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 charge
otherwise permitted by the Conduct Rules of the National Association of
Securities Dealers, Inc. (the "NASD").

YOUR ACCOUNT AND DOING BUSINESS
WITH US
 
Class D shares of the Portfolio are sold on a continuous basis and may be
purchased directly from the Trust's Distributor, SEI Financial Services Company.

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 DISTRIBUTOR  Application forms can be obtained by calling
                      1-800-437-6016. Class D shares of the Portfolio are

                      application and a check (or other negotiable bank
                      instrument or money order) payable to "Class D (Treasury
                      Securities 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

Automatic
Investment Plan
("AIP")               You may systematically buy Class D shares through
                      deductions from your checking or savings account, 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 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
                      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.
                             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.

                                                     When making an exchange,
                                                     you authorize the sale
                                                     of your shares of one or
                                                     more Portfolios in order

                                                     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.

HOW TO SELL SHARES
THROUGH THE
DISTRIBUTOR
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. A wire redemption charge
                      (presently $10.00) will be deducted 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 request or if the check cannot be honored
                      because of insufficient funds or other valid reasons.

INVESTMENT
OBJECTIVE AND
POLICIES
 
TREASURY SECURITIES
PORTFOLIO             The investment objective of the Treasury Securities 
                      Portfolio is to preserve principal value and maintain a
                      high degree of liquidity while providing current income.
                             The Treasury Securities Portfolio invests
                      exclusively in U.S. Treasury obligations and repurchase
                      agreements involving such obligations. The repurchase
                      agreement dealers selected for the Treasury Securities
                      Portfolio must meet certain creditworthiness criteria
                      established by Standard & Poor's Corporation ("S&P").
                             There can be no assurance that the Portfolio
                      will achieve its investment objective.
 
GENERAL
INVESTMENT
POLICIES
 
                      In purchasing obligations, the Portfolio complies with the
                      requirements of Rule 2a-7 under 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.

                                                     to make sure that the
                                                     investment objective
                                                     matches your own

                         assets of the Portfolio (based on fair market value at
                         the time of investment) would be invested in the
                         securities of such issuer; provided, however, that the
                         Portfolio may temporarily invest up to 25% of its
                         total assets without regard to this restriction as
                         permitted by Rule 2a-7.

                         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 (a) domestic banks and (b)
                         obligations issued or guaranteed by the U.S. Government
                         or its agencies and instrumentalities.

                         value of the total assets of the Portfolio. This
                         borrowing provision is included solely to facilitate
                         the orderly sale of portfolio securities to accommodate
                         substantial redemption requests if they should occur
                         and is not for investment purposes. All borrowings will
                         be repaid before making additional investments for the
                         Portfolio 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

                             For its management services, SEI Management is
                      entitled to a fee, which is calculated daily and paid
                      monthly, at an annual rate of .42% of the average daily
                      net assets of the Treasury Securities Portfolio. SEI
                      Management has contractually agreed to waive a portion of
                      its fee in order to limit total operating expenses on an
                      annualized basis to not more than .84% of the average

                      an annualized basis. For the fiscal year ended June 30,
                      1996, the Portfolio paid management fees, after fee
                      waivers, of .33% of the Portfolio's average daily net
                      assets.

                      of the Trust.
                             As of September 30,
                      1996, the Adviser had

                      authority with respect to
                      approximately $123.8 billion
                      of assets, including the
                      assets of the Trust and SEI

                      investment advisory services to investment companies since
                      1933, and to investment counseling clients since 1960. The

                      SEI Financial Services Company (the "Distributor"), a
                      wholly-owned subsidiary of SEI Corporation, serves as each
                      Portfolio's distributor pursuant to a distribution
                      agreement (the "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 Investment Company Act of 1940, as amended (the

                      servicing plan for its Class A shares (the "Class A

                                                     adviser manages the

                                                     conditions, and

                      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 the 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 the 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. Currently, the Distributor is taking this
                      compensation payment under the Class D Plan at a rate of
                      .20% of the Portfolio's average daily net assets, on an
                      annualized basis, attributable to Class D shares.
                             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
                      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.

                      From time to time, the Portfolio may advertise "current
                      yield" and "effective compound yield." These figures will
                      fluctuate, as they 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 an 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
 
                                       12
<PAGE>   33
 
                      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 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.
                             For the Portfolio, the performance of the Class A
                      shares will normally be higher than the performance of the
                      Class D shares of the Portfolio because of 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, state, or local income tax treatment of
                      the Portfolio or its shareholders. In addition, 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
                      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, so as to be relieved of
                      federal income tax on net investment company taxable
                      income and net capital gains (the excess of net long-term
                      capital gain over net short-term capital losses)
                      distributed to shareholders.
 
Tax Status
of Distributions
                      The Portfolio will distribute substantially all of its net
                      investment income (including net short-term capital gains)
                      and net capital gain to shareholders. Dividends from net
                      investment company taxable income are taxable to
                      shareholders as ordinary income, whether received in cash
                      or in additional shares, to the extent of the Portfolio's
                      earning and profits. Distributions of net capital gains
                      are taxable to shareholders as long-term capital gains
                      regardless of how long shareholders have held their shares
                      and regardless of whether the distributions are received
                      in cash or

                      in additional shares. Dividends and distributions of
                      capital gains paid by the Portfolio do not qualify for
                      the dividends-received deduction for corporate
                      shareholders. The Portfolio will make annual reports to
                      shareholders on the federal income tax status of all
                      distributions.
                             Dividends declared by the Portfolio in October,
                      November or December of any year and payable to
                      shareholders of record on a date in such a month will be
                      deemed to have been paid by the Portfolio and received by
                      the shareholders on December 31 of the year declared if
                      paid by the Portfolio at any time during the following
                      January.

                                                     [SYMBOL]  DISTRIBUTIONS
 
                                                     The Portfolio
                                                     distributes income
                                                     dividends and capital
                                                     gains. Income dividends
                                                     represent the earnings
                                                     from the Portfolio's
                                                     investments; capital
                                                     gains distributions
                                                     occur when investments
                                                     in the Portfolio are
                                                     sold for more than the
                                                     original purchase price.
                             The Portfolio intends to make sufficient
                      distributions prior to the end of each calendar year, to
                      avoid liability for the federal excise tax applicable to
                      regulated investment companies.
                             With respect to investments in U.S. Treasury
                      STRIPS, which are sold at original issue discount and thus
                      do not make periodic cash interest payments, the Portfolio
                      will be required to include as part of its current income
                      the imputed interest on such obligations even though the
                      Portfolio has not received any interest payments on such
                      obligations during that period. Because the Portfolio
                      distributes all of its net investment income to its
                      shareholders, the Portfolio may have to sell portfolio
                      securities to distribute such imputed income, which may
                      occur at a time when the Adviser would not have chosen to
                      sell such securities and, which may result in a taxable
                      gain or loss.
                             Investment income received by the Portfolio on
                      direct U.S. Government obligations is exempt from tax at
                      the state level when received directly by the Portfolio
                      and may be exempt, depending on the state, when received
                      by a shareholder as income dividends from the Portfolio
                      provided certain state-specific conditions are satisfied.
                      Interest received on repurchase agreements collateralized
                      by U.S. Government obligations normally is not exempt from
                      state taxation. The Portfolio will inform shareholders
                      annually of the percentage of income and distributions
                      derived from direct U.S. Government obligations.
                      Shareholders should consult their tax advisers to
                      determine whether any portion of the income dividends
                      received from the Portfolio is considered tax exempt in
                      their particular states.
                             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 ("Business
                      Days"). However, shares of the Portfolio cannot be
                      purchased by Federal Reserve wire on Federal holidays. All
                      purchase, exchange and redemption requests received in
                      "good order" will be effective as of the Business Day
                      received by the Transfer 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.
                             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 that 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 10 or more 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"). 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
Net Asset Value
is Determined
                      The net asset value per share of the Portfolio is
                      determined by dividing the total market value of its
                      investments and other assets, less any liabilities, by the
                      total number of outstanding shares of the Portfolio.
                      Although the methodology and procedures for determining
                      net asset value per share are identical for both classes
                      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/or shareholder servicing
                      fees charged to each class and the 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. A Notary public
                      cannot guarantee signatures. The signature guarantee
                      requirement will be waived if all of the following
                      conditions apply: (1) the redemption is for not more than
                      $5,000 worth of shares, (2) the redemption check is
                      payable to the shareholder(s) of record, and (3) the
                      redemption check is mailed to the shareholder(s) at his or
                      her address of record. The Trust and the Transfer Agent
                      reserve the right to amend these requirements without
                      notice.

Telephone/Wire
Instructions          Redemption orders may be placed by telephone. Neither the
                      Trust nor the Transfer Agent will be responsible for any
                      loss, liability, cost or expense for acting upon wire
                      instructions 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 and
                      may wish to consider placing orders by other means.
 
Systematic
Withdrawal
Plan ("SWP")
                      Please note that if withdrawals exceed income dividends,
                      your invested principal in the account will be depleted.
                      Thus, depending upon the frequency and amounts of the
                      withdrawal payments and/or any fluctuations in the net
                      asset value per share, your original investment could be
                      exhausted entirely. To participate in the SWP, you must
                      have your dividends automatically reinvested. You may
                      change or cancel the SWP at any time, upon written notice
                      to the Transfer Agent.
 
How to
Close your Account    An account may be closed by providing written notice to
                      the Transfer Agent. You may also close your account by
                      telephone if you have previously elected telephone options
                      on your account application.
 
GENERAL

The Trust             SEI Liquid Asset Trust was organized as a Massachusetts
                      business trust under a Declaration of Trust dated July 20,
                      1981. The Declaration of Trust permits the Trust to offer
                      separate Portfolios of shares and different classes of
                      each Portfolio. Shareholders may purchase shares in
                      Portfolios through two separate classes: Class A and Class
                      D, which provide for variation in distribution,
                      shareholder servicing and transfer agent costs, voting
                      rights, dividends. This Prospectus offers the Class D
                      shares of the Trust's Treasury Securities Portfolio. In
                      addition to the Portfolio, the Trust consists of the
                      following other portfolios: Government Securities
                      Portfolio, Institutional Cash Portfolio, Prime Obligation
                      Portfolio, and Money Market Portfolio. Additional

                      for shares of any Portfolio or class and all assets of
                      such Portfolio or class belong to that Portfolio or class
                      and are 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

                      expenses, litigation and other extraordinary expenses,

                      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 of the
                      Trust will vote separately on matters relating solely to
                      that Portfolio or class. 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 DST Systems,
                      Inc., P.O. Box 419240, Kansas City, MO 64141-6240.
 
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.
                      Currently, capital gains (the excess of net long-term
                      capital gain over net short-term capital loss) realized,
                      if any, are distributed at least annually.
                             Shareholders in the Portfolio 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.
                             Dividends and distributions of the Portfolio are
                      paid by the Portfolio on a per-share basis. The value of
                      each share will be reduced by the amount of any such
                      payment. If shares are purchased shortly before the record
                      date for a dividend or the distribution of capital gains,
                      a shareholder will pay the full price for the shares and
                      receive some portion of the price back as a taxable
                      dividend or 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:
 
Repurchase Agreements Repurchase agreements are agreements by which the
                      Portfolio obtains a security and simultaneously commits to
                      return the security to the seller at an agreed upon price
                      on an agreed upon date within a number of days from the
                      date of purchase. The Portfolio or its agent will have
                      actual or constructive possession of the securities held
                      as collateral for the repurchase agreement. Collateral
                      must be maintained at a value at least equal to 100% of
                      the resale price. 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 Portfolio will enter into repurchase
                      agreements only with financial institutions deemed to
                      present minimal risk of bankruptcy during the term of the
                      agreement based on established guidelines. Repurchase
                      agreements are considered loans under the 1940 Act.
 
U.S. Treasury
Obligations           U.S. Treasury Obligations consist of bills, notes and
                      bonds issued by the U.S. Treasury, as well as separately
                      traded interest and principal component parts of such
                      obligations, known as Separately Traded Registered
                      Interest and Principal Securities ("STRIPS"), that are
                      transferable through the federal book-entry system.
                             STRIPS are sold as zero coupon securities which
                      means that they are sold at a substantial discount and
                      redeemed at face value at their maturity date without
                      interim cash payments of interest or principal. This
                      discount is accreted over the life of the security, and
                      such accretion will constitute the income earned on the
                      security for both accounting and tax purposes. Because of
                      these features, such securities may be subject to greater
                      interest rate volatility than interest paying permitted
                      investments. See also "Taxes."

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 the Portfolio
                      generally purchases securities on a when-issued or forward
                      commitment basis with the intention of actually acquiring
                      securities, the Portfolio may dispose of a when-issued
                      security or forward commitment prior to settlement if the
                      Adviser deems it appropriate to do so.

THE TRUST

SEI Liquid Asset Trust (the "Trust") is a diversified, open-end management
investment company established as a Massachusetts business trust pursuant to a
Declaration of Trust dated July 20, 1981. The Declaration of Trust permits the
Trust to offer separate series ("portfolios") of units of beneficial interest
("shares") and separate classes of portfolios.  Except for differences between
Class A and Class D shares pertaining to distribution and shareholder servicing
plans, voting rights, dividends and transfer agent expenses, each share of each
portfolio represents an equal proportionate interest in that portfolio with
each other share of that portfolio.

This Statement of Additional Information relates to the shares of the following
Portfolios:  Treasury Securities, Government Securities, Prime Obligation,
Institutional Cash and Money Market Portfolios (each a "Portfolio" and,
together, the "Portfolios"), and any classes of the Portfolios.

DESCRIPTION OF PERMITTED INVESTMENTS

COMMERCIAL PAPER --  The Prime Obligation and Money Market Portfolios may
invest in commercial paper.  Commercial paper is the term used to designate
unsecured, short-term promissory notes issued by corporations and other
entities.

COMMERCIAL PAPER RATINGS -- The following descriptions of commercial paper
ratings have been published by Standard & Poor's Corporation ("S&P"), Moody's
Investors Service, Inc. ("Moody's"), Fitch Investors Service, Inc. ("Fitch"),
Duff & Phelps, Inc. ("Duff"), Thomson BankWatch ("Thomson") and IBCA Limited
and IBCA, Inc. (together, "IBCA").

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 and 2 to indicate the relative degree of safety.  Issues rated
A-1+ are those with an "overwhelming degree" of credit protection.  Those rated
A-1, the highest rating category, reflect a "very strong" degree of safety
regarding timely payment.  Those rated A-2, the second highest rating category,
reflect a safety regarding timely payment, but not as high as A-1.

Moody's employs two designations, judged to be high grade commercial paper, to
indicate the relative repayment capacity of rated issuers as follows:

         Prime-1 Superior Quality
         Prime-2 Strong Quality

The rating Fitch-1 (Highest Grade) is the highest commercial paper rating
assigned by Fitch.  Paper rated Fitch-1 is regarded as having the strongest
degree of assurance for timely payment.  The rating Fitch-2 (Very Good Grade)
is the second highest commercial paper rating assigned by Fitch which reflects
an assurance of timely payment only slightly lower in degree than the strongest
issues.





                                      S-2
<PAGE>   43
The rating Duff-1 is the highest commercial paper rating assigned by Duff.
Paper rated Duff-1 is regarded as having very high certainty of timely payment
with excellent liquidity factors which are supported by ample asset protection.
Risk factors are minor.  Paper rated Duff-2, the second highest rating
category, is regarded as having good certainty of timely payment, good access
to capital markets and sound liquidity factors and company fundamentals.  Risk
factors are small.

The rating TBW-1 is the highest commercial paper rating assigned by Thomson.
Paper rated TBW-1 indicates a very high likelihood that principal and interest
will be paid on a timely basis.  The rating TBW-2 is the second-highest rating
assigned category by Thomson.  The relative degree of safety regarding timely
repayment of principal and interest is strong.  However, the relative degree of
safety is not as high as for issues rated TBW-1.

The designation A1, the highest rating category established by IBCA, indicates
that the obligation is supported by a very strong capacity for timely
repayment.  Those obligations rated A1+ are supported by the highest capacity
for timely repayment.  Obligations rated A2, the second highest rating
category, are supported by a strong capacity for timely repayment, although
such capacity may be susceptible to adverse changes in business, economic or
financial conditions.

DESCRIPTION OF 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 rate 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 degree.

Bonds which are rated Aaa by Moody's are judged to be 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
sable, 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 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 of protection may not be as
large as in Aaa securities or fluctuation of protective elements may be of
greater amplitude or there may be other elements present which make the
long-term risks appear somewhat larger than in Aaa securities.

Bonds rated AAA are judged by Fitch to be strictly high grade, broadly
marketable, suitable for investment by trustees and fiduciary institutions
liable to but slight market fluctuation other than through changes in the money
rate.  The prime feature of an AAA bond is a showing of earnings several times
or many times interest requirements, with such stability of applicable earnings
that safety is beyond reasonable question whatever changes occur in conditions.
Bonds rate AA are judged by Fitch to be of safety virtually beyond question and
are readily salable, whose merits are not unlike those of the AAA class, but
whose margin of safety is less strikingly broad.  The issue





                                      S-3
<PAGE>   44
may be the obligation of a small company, strongly secured but influenced as to
rating by the lesser financial power of the enterprise and more local type
market.

Bonds rated Duff-1 are judged by Duff to be of the highest credit quality with
negligible risk factors; only slightly more than U.S. Treasury debt.  Bonds
rated Duff-2, are judged by Duff to be of high credit quality with strong
protection factors.  Risk is modest but may vary slightly from time to time
because of economic conditions.

Bonds which are rated AAA are judged by Thomson to be of the highest category.
The ability to repay principal and interest on a timely basis is very high.
Bonds rated AA are judged by Thomson to be of a superior ability to repay
principal and interest on a timely basis, with limited incremental risk
compared to issues rated in the highest category.

Obligations rated AAA by IBCA have the lowest expectation of investment risk.
Capacity for timely repayment of principal and interest is substantial, such
that adverse changes in business, economic or financial conditions are unlikely
to increase investment risk significantly.  Obligations for which there is a
very low expectation of investment risk are rated AA by IBCA.  Capacity for
timely repayment of principal and interest is substantial.  Adverse changes in
business, economic or financial conditions may increase investment risk albeit
not very significantly.

FOREIGN SECURITIES -- The Money Market Portfolio may invest in U.S. dollar
denominated obligations of foreign issuers, including foreign branches of U.S.
commercial banks, and of U.S. and London branches of foreign banks.  These
instruments may subject the Portfolio to investment risks that differ in some
respects from those related to investments in obligations of U.S. domestic
issuers.  Such risks include future adverse political and economic
developments, the possible imposition of withholding taxes on interest or other
income, possible seizure, nationalization, or expropriation of foreign
deposits, the possible establishment of exchange controls or taxation at the
source, greater fluctuations in value due to changes in exchange rates, or the
adoption of other foreign governmental restrictions which might adversely
affect the payment of principal and interest on such obligations.  Such
investments may also entail higher custodial fees and sales commissions than
domestic investments.  Foreign issuers of securities or obligations are often
subject to accounting treatment and engage in business practices different from
those respecting domestic issuers of similar securities or obligations.
Foreign branches of U.S. banks and foreign banks may be subject to less
stringent reserve requirements than those applicable to domestic branches of
U.S. banks.

GNMA SECURITIES -- The Prime Obligation, Money Market and Government Securities
Portfolios may invest in securities issued by the Government National Mortgage
Association ("GNMA"), a wholly-owned U.S. Government Securities corporation
which guarantees the timely payment of principal and interest.  However, any
premiums paid to purchase these instruments are not subject to GNMA guarantees.
The market value and interest yield of these instruments can vary due to market
interest rate fluctuations and early prepayments of underlying mortgages.





                                      S-4
<PAGE>   45
These securities represent ownership in a pool of Federally insured mortgage
loans.  GNMA certificates consist of underlying mortgages with a maximum
maturity of 30 years.  However, due to scheduled and unscheduled principal
payments, GNMA certificates have a shorter average maturity and, therefore,
less principal volatility than a comparable 30-year mortgage-backed bond. Since
prepayment rates vary widely, it is not possible to accurately predict the
average maturity of a particular GNMA pool.  The scheduled monthly interest and
principal payments relating to mortgages in the pool will be "passed through"
to investors.  GNMA securities differ from conventional bonds in that principal
is paid back to the certificate holders over the life of the loan rather than
at maturity.  As a result, the Portfolios will receive monthly scheduled
payments of principal and interest. In addition, the Portfolios may receive
unscheduled principal payments representing prepayments on the underlying
mortgages.  Any prepayments will be reinvested at the then-prevailing interest
rate.

Although GNMA certificates may offer yields higher than those available from
other types of U.S. Government Securities, GNMA certificates may be less
effective than other types of securities as a means of "locking in" attractive
long-term rates because of the prepayment feature.  Due to this prepayment
feature, GNMA certificates tend not to increase in value as much as most other
debt securities when interest rates decline.

MUNICIPAL SECURITIES --The Money Market Portfolio may invest in Municipal
Securities.  The two principal classifications of Municipal Securities are
"general obligation" and "revenue" issues.  General obligation issues are
issues involving the credit of an issuer possessing taxing power and are
payable from the issuer's general unrestricted revenues, although the
characteristics and method of enforcement of general obligation issues may vary
according to the law applicable to the particular issuer.  Revenue issues are
payable only from the revenues derived from a particular facility or class of
facilities or other specific revenue source.  A Portfolio may also invest in
"moral obligation" issues, which are normally issued by special purpose
authorities.  Moral obligation issues are not backed by the full faith and
credit of the state but are generally backed by the agreement of the issuing
authority to request appropriations from the state legislative body.  Municipal
Securities include debt obligations issued by governmental entities to obtain
funds for various public purposes, such as the construction of a wide range of
public facilities, the refunding of outstanding obligations, the payment of
general operating expenses, and the extension of loans to other public
institutions and facilities.  Certain private activity bonds that are issued by
or on behalf of public authorities to finance various privately-owned or
operated facilities are included within the term "Municipal Securities."
Private activity bonds and industrial development bonds are generally revenue
bonds, the credit and quality of which are directly related to the credit of
the private user of the facilities.

Municipal Securities may also include general obligation notes, tax
anticipation notes, bond anticipation notes, revenue anticipation notes,
project notes, certificates of indebtedness, demand notes, tax-exempt
commercial paper, construction loan notes and other forms of short-term,
tax-exempt loans.  Such instruments are issued with a short-term maturity in
anticipation of the receipt of tax funds, the proceeds of bond placements or
other revenues.  Project notes are issued by a





                                      S-5
<PAGE>   46
state or local housing agency and are sold by the Department of Housing and
Urban Development.  While the issuing agency has the primary obligation with
respect to its project notes, they are also secured by the full faith and
credit of the United States through agreements with the issuing authority which
provide that, if required, the federal government will lend the issuer an
amount equal to the principal of and interest on the project notes.

The quality of Municipal Securities, both within a particular classification
and between classifications, will vary, and the yields on Municipal Securities
depend upon a variety of factors, including general money market conditions,
the financial condition of the issuer (or other entity whose financial
resources are supporting the securities), general conditions of the municipal
bond market, the size of a particular offering, the maturity of the obligation
and the rating(s) of the issue.  In this regard, it should be emphasized that
the ratings of any nationally recognized statistical rating organization
("NRSRO") are general and are not absolute standards of quality.  Municipal
Securities with the same maturity, interest rate and rating(s) may have
different yields, while Municipal Securities of the same maturity and interest
rate with different rating(s) may have the same yield.

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

MUNICIPAL NOTE RATINGS:  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 and such securities have strong
protection afforded by established cash flows, superior liquidity support
and/or demonstrated access to the market for refinancing.  Short-term Municipal
Securities rated MIG-2 and VMIG-2 are of high quality and their margins of
protection are ample, although not so large as in the preceding group.

An S&P note rating reflects the liquidity concerns and market access risks
unique to notes.  Notes due in three years or less will likely receive a note
rating.  Notes maturing beyond three years will most likely receive a long-term
debt rating.  The following criteria will be used in making that assessment.

         o       Amortization schedule (the larger the final maturity relative
                 to other maturities, the more likely it will be treated as a
                 note).

         o       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).





                                      S-6
<PAGE>   47
Note rate 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.

REPURCHASE AGREEMENTS -- The Treasury Securities, Government Securities, Prime
Obligation, and Money Market Portfolios may enter into repurchase agreements,
which 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 involved bears a
risk of loss in the event that the other party to a repurchase agreement
defaults on its obligations and the Portfolio is delayed or prevented from
exercising its rights to dispose of the securities held as collateral.
Wellington Management Company, LLP (the "Adviser") enters into repurchase
agreements only with financial institutions which it deems to present minimal
risk of bankruptcy during the term of the agreement based on guidelines
established by 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 Adviser monitors compliance with this requirement.
Under all repurchase agreements entered into by the Portfolios, the Portfolios
will take actual or constructive 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 delay and costs
in selling the security and may suffer a loss of principal and interest if the
Portfolios are treated as an unsecured creditor.

U.S. GOVERNMENT AGENCY OBLIGATIONS -- The Government Securities, Prime
Obligation, and Money Market Portfolios may invest in obligations of agencies
of the United States Government, which consist of obligations issued by, among
others, the Export Import Bank of the United States, Farmers Home
Administration, Federal Farm Credit Bank, Federal Housing Administration,
Government National Mortgage Association, Maritime Administration, Small
Business Administration, and The Tennessee Valley Authority.  The Government
Securities, Prime Obligation, and Money Market Portfolios may purchase
securities guaranteed by the Government National Mortgage Association, which
represent participation in Veterans Administration and Federal Housing
Administration backed mortgage pools.  Obligations of instrumentalities of the
United States Government include securities issued by, among others, Federal
Home Loan Banks, Federal Home Loan Mortgage Corporation, Federal Intermediate
Credit Banks, Federal Land Banks,





                                      S-7
<PAGE>   48
Federal National Mortgage Association and the United States Postal Service.
Some of these securities are supported by the full faith and credit of the
United States Treasury (e.g., GNMA Securities), others are supported by the
right of the issuer to borrow from the Treasury, and still others are supported
only by the credit of the instrumentality (e.g., FNMA 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 the value of the obligation prior to maturity.  The Portfolios do not
intend to purchase securities issued by the World Bank, the Inter-American
Development Bank or the Asian Development Bank.

VARIABLE OR FLOATING RATE INSTRUMENTS -- Each Portfolio may invest in variable
or floating rate instruments, which may involve a demand feature and may
include variable amount master demand notes which may or may not be backed by
bank letters of credit.  Variable or floating rate instruments bear interest at
a rate which varies with changes in market rates.  The holder of an instrument
with a demand feature may tender the instrument back to the issuer at par prior
to maturity.  A variable amount master demand note is issued pursuant to a
written agreement between the issuer and the holder, its amount may be
increased by the holder or decreased by the holder or issuer, it is payable on
demand, and the rate of interest varies based upon an agreed formula.  The
quality of the underlying credit must, in the opinion of the Adviser, be
equivalent to the quality ratings applicable to permitted investments for each
Portfolio.  The Adviser will monitor on an ongoing basis the earning power,
cash flow, and liquidity ratios of the issuers of such instruments and will
similarly monitor the ability of an issuer of a demand instrument to pay
principal and interest on demand.

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 Management Agreement, unless terminated sooner as provided therein, shall
remain in effect for two years after the date of the Agreement and shall
continue in effect for successive periods of one year if such continuance is
specifically approved at least annually (i) by the Trustees of the Trust and
(ii) by the vote of a majority of the Trustees of the Trust, who are not
parties to the Management Agreement or interested persons (as that term is
defined in the Investment Company Act of 1940, as amended (the "1940 Act")) of
any such party, cast in person at a Board of Trustees meeting called for the
purpose of voting on such approval.  The Agreement may be terminated at any
time and without penalty by the Trustees of the Trust or by the Manager on not
less than 30 days' nor more than 60 days' written notice to the other party
thereto.  Any notice under the Management Agreement shall be given in writing,
addressed and delivered, or mailed postpaid, to the other party at the
designated mailing address of such party.

The Manager, a Delaware business trust, has its principal business offices at
680 East Swedesford Road, Wayne, Pennsylvania 19087-1658.  SEI Financial
Management Corporation ("SFM"), a wholly-owned subsidiary of SEI Corporation
("SEI"), is the owner of all of the beneficial interests in the Manager.  SEI
and its affiliates, 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 Manager 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 American Funds, Inc., First
American Investment Funds, Inc., Inventor Funds, Inc., Marquis Funds(R),
Monitor Funds, Morgan Grenfell Investment Trust, The PBHG Funds, Inc., The
Pillar Funds, Profit Funds Investment Trust, Rembrandt Funds(R), Santa Barbara
Group of Mutual Funds, Inc., 1784 Funds(R), SEI Asset Allocation Trust,  SEI
Daily Income Trust, SEI Index Funds, SEI Institutional Investments Trust, SEI
Institutional Managed Trust, SEI International Trust, SEI Tax Exempt Trust,
Stepstone Funds, STI Classic Funds, STI Classic Variable Trust, and Turner
Funds.

The Manager has agreed contractually to waive its fee in order to limit
operating expenses of the Portfolios to not more than .44% of average net
assets of the Class A shares and .84% of average net assets of the Class D
shares.  As to the Institutional Cash Portfolio only, this waiver is voluntary
and may be terminated at any time.  Shareholders will be notified in advance if
and when the waiver is terminated.  The Manager will not be required to bear
expenses of any Portfolio to an extent which would result in the Portfolio's
inability to qualify as a regulated investment company under provisions of the
Internal Revenue Code of 1986, as amended (the "Code"). The term "expenses" is
defined in such laws or regulations, and generally excludes brokerage
commissions, distribution expenses, taxes, interest, litigation and
extraordinary expenses.

For the fiscal years ended June 30, 1994, 1995 and 1996, the Portfolios paid
fees to the Manager as follows:

THE ADVISER

The Trust and Wellington Management Company, LLP ("the Adviser") have entered
into an investment advisory agreement (the "Advisory Agreement") dated October
30, 1985. The Advisory Agreement provides that the Adviser shall not be
protected against any liability to the Trust or its shareholders by reason of
willful misfeasance, bad faith or gross negligence on its part in the
performance of its duties or from reckless disregard of its obligations or
duties thereunder.

The continuance of the Advisory Agreement after the first two (2) years of the
Agreement must be specifically approved at least annually (i) by the vote of a
majority of the outstanding shares of that Portfolio or by the Trustees, and
(ii) by the vote of a majority of the Trustees who are not parties to the
Advisory Agreement or "interested persons" of any party thereto, cast in person
at a meeting called for the purpose of voting on such approval.  The Advisory
Agreement will terminate automatically in the event of its assignment, and is
terminable at any time without penalty by the Trustees of the Trust or, with
respect to a Portfolio, by a majority of the outstanding shares of that
Portfolio, on not less than 30 days' nor more than 60 days' written notice to

Trust's daily net assets up to $500 million, and .02% of the Trust's daily net
assets in excess of $500 million.  The fee is allocated among the Portfolios
based upon their relative net assets.

DISTRIBUTION AND SHAREHOLDER SERVICING

The Trust has adopted a Distribution Agreement for the Portfolios dated
November 29, 1982.  The Trust has also adopted a Class D Distribution Plan (the
"Class D Plan") for the Treasury Securities Portfolio in accordance with Rule
12b-1 under the 1940 Act, which regulates the 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 Class D Plan and the Distribution Agreement are in the best
interests of the Shareholders.  Continuance of the Class D Plan 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 Class D Plan requires that quarterly written
reports of amounts spent under the Plan and the purposes of such expenditures
be furnished to and reviewed by the Trustees.  The Class D Plan 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.  All
material amendments of the Class D Plan will require approval by a majority of
the Trustees of the Trust and of the Qualified Trustees.

The Class D Plan provides that the Trust will pay the Distributor a fee on the
Class D 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 adopted a shareholder servicing plan for its Class A shares
(the "Class A Plan").  Under this 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.

For the fiscal year ended June 30, 1996, the Portfolios incurred the following
distribution expenses:

FUNDAMENTAL INVESTMENT LIMITATIONS

The following investment limitations are fundamental policies of each Portfolio
which cannot be changed with respect to a Portfolio without the consent of the
holders of a majority of that Portfolio's outstanding shares.  The term
"majority of outstanding shares" means the vote of (i) 67% or more of a
Portfolio's shares present at a meeting, if not more than 50% of the
outstanding shares of a Portfolio are present or represented by proxy, or (ii)
more than 50% of a Portfolio's outstanding shares, whichever is less.

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 the total assets of
         that Portfolio. This borrowing provision is included solely to
         facilitate the orderly sale of portfolio securities to accommodate
         substantial redemption requests if they should occur and is not for
         investment purposes. All borrowings by a Portfolio will be repaid
         before making additional investments for that Portfolio and any
         interest on such borrowings will reduce the income of that Portfolio.

2.       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 total assets.

3.       Pledge, mortgage or hypothecate assets except to secure temporary
         borrowings, as described in the Prospectus, in aggregate amounts not
         to exceed 10% of the net assets of such Portfolio taken at fair market
         value at the time such loan is incurred.

4.       Invest in companies for the purpose of exercising control.

5.       Acquire more than 10% of the voting securities of any one issuer.

6.       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 purchase obligations issued by companies which invest in
         real estate, real estate limited partnerships, commodities or
         commodities contracts.

7.       Make short sales of securities, maintain a short position or purchase
         securities on margin, except that a Portfolio may obtain short-term
         credits as necessary for the clearance of security transactions.

8.       Act as an underwriter of securities of other issuers except as it may
         be deemed an underwriter in selling a portfolio security.





                                      S-16
<PAGE>   57
9.       Purchase securities of other investment companies except as permitted
         by the 1940 Act and the rules and regulations thereunder and, in any
         event, may not purchase securities of other open-end investment
         companies.  Under these rules and regulations, the Portfolios are
         prohibited from acquiring the securities of other investment companies
         if, as a result of such acquisition, a Portfolio owns more than 3% of
         the total voting stock of an investment company; securities issued by
         any one investment company represent more than 5% of the total
         Portfolio assets; or securities (other than treasury stock) issued by
         all investment companies represent more than 10% of the total assets
         of a Portfolio.  These investment companies typically incur fees that
         are separate from those fees incurred directly by a Portfolio.  A
         Portfolio's purchase of such investment companies results in the
         layering of expenses such that shareholders would indirectly bear a
         proportionate share of such investment companies' expenses, including
         advisory fees.

10.      Issue senior securities (as defined in the Investment Company Act of
         1940) except in connection with  permitted borrowings as described in
         the Prospectus and this Statement of Additional Information or as
         permitted by rule, regulation or order of the Securities and Exchange
         Commission.

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 U.S. Government, its agencies
         or instrumentalities, or (ii) municipal securities which are rated by
         at least two nationally recognized municipal bond rating services, if,
         as a result, more than 5% of the total assets (taken at fair market
         value) of the Portfolio would be invested in such securities.

13.      Purchase warrants, puts, calls, straddles, spreads or combinations
         thereof.

14.      Invest in interests in oil, gas or other mineral exploration or
         development programs.

15.      Purchase restricted securities (securities which must be registered
         under the Securities Act of 1933 before they may be offered or sold to
         the public) or other illiquid securities except as described in the
         Prospectus and this Statement of Additional Information.

Except with respect to the limitation on investing in illiquid securities, the
foregoing percentages will apply at the time of the purchase of a security and
shall not be considered violated unless an excess or deficiency occurs or
exists immediately after and as a result of a purchase of such security.

NON-FUNDAMENTAL INVESTMENT LIMITATIONS

The following investment limitation is a non-fundamental policy of the Trust
and may be changed without shareholder approval.

1.       The Government Securities and Prime Obligations Portfolios must
         maintain an average dollar-weighted portfolio maturity of 90 days or
         less.

PERFORMANCE

From time to time, each Portfolio may advertise its yield. These figures will
be based on historical earnings and are not intended to indicate future
performance.

The current yield of each Portfolio is calculated daily based upon the seven
days ending on the date of calculation ("base  period").  The yield is computed
by determining the net change (exclusive of capital changes) in the value of a
hypothetical pre-existing shareholder account having a balance of one share at
the beginning of the period, subtracting a hypothetical charge reflecting
deductions from shareholder accounts and dividing such net change by the value
of the account at the beginning of the same period to obtain the base period
return and multiplying the result by (365/7).  Realized and unrealized gains
and losses are not included in the calculation of the yield.

The Portfolios compute their effective compound yield by determining the net
changes, exclusive of capital changes, in the value of a hypothetical
pre-existing account having a balance of one share at the beginning of the
period, subtracting a hypothetical charge reflecting deductions from
shareholder accounts, and dividing the difference by the value of the account
at the beginning of the base period to obtain the base period return, and then
compounding the base period return by adding 1, raising the sum to a power
equal to 365 divided by 7, and subtracting 1 from the result, according to the
following formula:  Effective Yield = [(Base Period Return + 1)365/7 - 1].  The
current and the effective yields reflect the reinvestment of net income earned
daily on portfolio assets.

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 seven-day period ended June 30, 1996 the Portfolios' yield and
effective yield were as follows:

</TABLE>



DETERMINATION OF NET ASSET VALUE

Securities of the 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 a Portfolio
would receive if it sold the instrument.  During periods of declining interest
rates, the daily yield of a Portfolio may tend to be higher than a like
computation made by a company with identical investments utilizing a method of
valuation based upon market prices and estimates of market prices for all of
its portfolio securities.  Thus, if the use of amortized cost by the Trust
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.

The Trust's use of amortized cost valuation and the maintenance of the net
asset value of each Portfolio 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 in the
Portfolio 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
Adviser will determine that an obligation presents minimal credit risks or that
unrated instruments are of





                                      S-19
<PAGE>   60
comparable quality in accordance with guidelines established by the Trustees.
The Trustees must approve or ratify the purchase of any unrated securities.  In
addition, investments in second tier securities are subject to the further
constraints that (i) no more than 5% of a Portfolio's assets may be invested in
such securities in the aggregate, and (ii) any investment in such securities of
one issuer is limited to the greater of 1% of the Portfolio's total assets or
$1 million.  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.

PURCHASE AND REDEMPTION OF SHARES

Purchases and redemptions of shares of the Funds may be made on any day the New
York Stock Exchange is open for business.  Currently, the following holidays
are observed by the Trust:  New Year's Day, Presidents' Day, Good Friday,
Memorial Day, Independence Day, Labor Day, Thanksgiving Day and Christmas Day.

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 by order permit.  The
Trust also reserves the right to suspend sales of shares of the Portfolio for
any period during which the New York Stock Exchange, the Manager, the Adviser,
the Distributor and/or the Custodian are not open for business.

State Securities laws regarding sub-administrators may differ from the
interpretations of federal law expressed herein and banks and financial
institutions acting in that capacity may be required to register as dealers
pursuant to state law.

SHAREHOLDER SERVICES (CLASS D SHARES)

STOP-PAYMENT REQUESTS: 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.

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 certain eligible portfolios reaches a
discount level.  See "Purchase and Redemption of Shares" in the Prospectuses
for the sales charge on quantity purchases.

LETTER OF INTENT:  The reduced sales shares 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 holder in escrow by the Manager 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 of 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.

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 Portfolios and/or classes in which such
automatic investments are to be made and consider the differences in investment
objectives and policies before making any investment.

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 Portfolio 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.





                                      S-21
<PAGE>   62
EXCHANGE PRIVILEGE: Some or all of the shares of the Portfolio for which
payment has been received (i.e., an established account) may be exchanged, at
their net asset value, plus any applicable sales charge, for Class D shares of
the Trust, SEI Tax Exempt Trust, SEI International Trust and SEI Institutional
Managed Trust or at their net asset value for Class D shares of other
portfolios of such trusts that do not have sales charges.  Exchanges will be
made only after proper instructions in writing or by telephone (an "Exchange
Request") are received for an established account by the Distributor.

A shareholder may exchange a Portfolio's Class D shares, 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 to be exchanged and the purchase of the
shares of the other Portfolio.  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, as defined in the Prospectuses of
the Trust, prior to the close of the New York Stock Exchange, the exchange
will be effective 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
Portfolios, and thus the purchase of shares of the other 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

The following is only a summary of certain tax considerations generally
affecting a Portfolio and its shareholders, and is not intended as a substitute
for careful tax planning.  Shareholders are urged to consult their tax advisors
with specific reference to their own tax situations, including their state and
local tax liabilities.

FEDERAL INCOME TAXES

The following discussion of federal income tax consequences is based on the
Internal Revenue Code of 1986, as amended (the "Code"), and the regulations
issued thereunder as in effect on the date of this Statement of Additional
Information.  New legislation, as well as administrative changes or court
decisions, may significantly change the conclusions expressed herein, and may
have a retroactive effect with respect to the transactions contemplated herein.





                                      S-22
<PAGE>   63
Each Portfolio intends to qualify as a regulated investment company ("RIC") as
defined under Subchapter M of the Code. By following such a policy, each of the
Portfolios expects to eliminate or reduce to a nominal amount the federal
income taxes to which such Portfolio may be subject.

In order to qualify for treatment as a RIC, a Portfolio must distribute
annually to its shareholders at least the sum of 90% of its net interest income
excludable from gross income plus 90% of its investment company taxable income
(generally, net investment income plus net short-term capital gain) (the
"Distribution Requirement") and also must meet several additional requirements.
Among these requirements are the following: (i) at least 90% of a Portfolio's
gross income each taxable year must be derived from dividends, interest,
payments with respect to securities loans, and gains from the sale or other
disposition of stock or securities, or other income derived with respect to its
business of investing in such stock or securities; (ii) less than 30% of a
Portfolio's gross income each taxable year must be derived from the sale or
other disposition of stocks, securities or certain other investments held for
less than three months; (iii) at the close of each quarter of a Portfolio's
taxable year, at least 50% of the value of its total assets must be represented
by cash and cash items, U.S. government securities, securities of other RIC's,
and other securities, with such other securities limited, in respect of any one
issuer, to an amount that does not exceed 5% of the value of a Portfolio's
assets and that does not represent more than 10% of the outstanding voting
securities of such issuer; and (iv) at the close of each quarter of a
Portfolio's taxable year, not more than 25% of the value of its assets may be
invested in securities (other than U.S. government securities or the securities
of other RIC's) of any one issuer or of two or more issuers which are engaged
in the same, similar or related trades or businesses if the Portfolio owns at
least 20% of the voting power of such issuers.

Notwithstanding the Distribution Requirement described above, which only
requires a Portfolio to distribute at least 90% of its annual investment
company taxable income and does not require any minimum distribution of net
capital gain (the excess of net long-term capital gain over net short-term
capital loss), a Portfolio will 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 for that year 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.

If capital gain distributions have been made with respect to shares that are
sold at a loss after being held for six months or less, the loss is treated as
a long-term capital loss to the extent of the previous capital gain
distributions.

If a Portfolio fails to qualify as a RIC for any year, all of its taxable
income will be subject to tax at regular corporate rates without any deduction
for distributions to shareholders, and its distributions (including capital
gains distributions) will be taxable as ordinary income dividends to its
shareholders, subject to the dividends received deduction for corporate
shareholders.  Otherwise, distributions to shareholders generally will not be
eligible for the dividends received deduction.





                                      S-23
<PAGE>   64
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 state and
local law, distributions by the Portfolio to shareholders and the ownership of
shares may be subject to state and local taxes.

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 Adviser is 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 Adviser
generally seeks 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 Securities and Exchange Commission.

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 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 Adviser under the
Advisory Agreements, and the expenses of the 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.  Where possible, the 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 generally are traded on a net basis and
normally do not 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.

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 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.





                                      S-24
<PAGE>   65
For the Trust's fiscal years ended June 30, 1994, 1995 and 1996, no brokerage
fees were paid.

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 of a Portfolio upon liquidation of that
Portfolio entitles a shareholder to a pro rata share in the net assets of that
Portfolio, after taking into account certain 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.  Any consideration received by the Trust for shares of any
additional Portfolio and assets in which such consideration is invested would
belong to that Portfolio and would be subject to the liabilities related
thereto.  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 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 willful 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 the Trust could, under
certain circumstances, be held personally liable for the obligations of the
Trust.  However, the possibility of the shareholders' incurring financial loss
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.  The Declaration of Trust provides for indemnification out of the
Trust's property for any shareholder held personally liable for the obligations
of the Trust.

5% SHAREHOLDERS

As of  August 1, 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.
