This Prospectus sets forth concisely information about the above-referenced
Portfolios that an investor needs to know before investing. Please read this
Prospectus carefully, and keep it on file for future reference.     
   
A Statement of Additional Information dated October 30, 1995, has been filed
with the Securities and Exchange Commission and is available upon request and
without charge by writing the Distributor, SEI Financial Services Company, 680
East Swedesford Road, Wayne, Pennsylvania 19087-1658, or by calling 1-800-342-
5734. The Statement of Additional Information is incorporated into this
Prospectus by reference.     
   
SEI Liquid Asset Trust (the "Trust") is an open-end management investment
company certain classes of which offer financial institutions a convenient
means of investing their own funds, or funds for which they act in a fiduciary,
agency or custodial capacity, in one or more professionally managed diversified
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
offers Class A shares of each of the Trust's five money market portfolios
(each, 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.
 
- --------------------------------------------------------------------------------
   
THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION, NOR HAS THE SECURITIES
AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE AC-
CURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE CONTRARY IS A
CRIMINAL OFFENSE.     
    
 THE TRUST'S SHARES ARE NOT DEPOSITS OR OBLIGATIONS OF, OR GUARANTEED
 OR ENDORSED BY, ANY BANK. THE SHARES ARE NOT FEDERALLY INSURED BY
 THE FEDERAL DEPOSIT INSURANCE CORPORATION, THE FEDERAL RESERVE BOARD
 OR ANY OTHER GOVERNMENT AGENCY. INVESTMENT IN THE SHARES INVOLVES
 RISK, INCLUDING POSSIBLE LOSS OF THE PRINCIPAL AMOUNT INVESTED.

1 The Manager has agreed contractually to waive its fee in an amount that
  limits the total operating expenses of such Portfolio to not more than .44%
  of its average net assets, except for the Institutional Cash Portfolio for
  which the 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,
  Institutional Cash and Money Market Portfolios, would be .45%, .45%, .45%,
  .39% and .45%, respectively, and, total operating expenses for the Treasury
  Securities, Government Securities, Prime Obligation and Money Market
  Portfolios would be .53%, .53%, .53%, and .53%, respectively, for the fiscal
  year ended June 30, 1995. Additional information may be found under "The
  Manager and Shareholder Servicing Agent," "The Adviser" and "Distribution."
         
2 The 12b-1 fees shown reflect each Portfolio's current 12b-1 budget for
  reimbursement of expenses except that there has been a waiver of any 12b-1
  fees for the Institutional Cash Portfolio. Absent this waiver, total
  operating expenses for the Institutional Cash Portfolio would be .48%.     
   
3 Other Expenses for the Money Market Portfolio are based on estimated amounts
  for the current fiscal year.

THE EXAMPLE SHOULD NOT BE CONSIDERED A REPRESENTATION OF FUTURE EXPENSES.
ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN. The purpose of this
table is to assist the investor in understanding the various costs and expenses
that may be directly or indirectly borne by investors in the Portfolios. A
person who purchases shares through a financial institution may be charged
separate fees by that institution. The information set forth in the foregoing
table and example relates only to the Portfolios' Class A shares. 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. Additional information regarding these differences may be found
under "The Manager and Shareholder Servicing Agent," "The Adviser" and
"Distribution." Long-term shareholders may eventually pay more than the
economic equivalent of the maximum front-end sales charges otherwise permitted
by the Rules of Fair Practice (the "Rules") of the National Association of
Securities Dealers, Inc. (the "NASD").

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. The quality, maturity and
                  diversification requirements of the Government Securities
                  and Prime Obligation Portfolios are more restrictive than
                  those imposed by Rule 2a-7. If Shareholders of these
                  Portfolios elect to be governed by Rule 2a-7 in the future,
                  the Portfolios will become subject to the Rule 2a-7
                  restrictions applicable to the Trust's other Portfolios.
                  Rule 2a-7's 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 and securities rated by only one NRSRO 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, 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 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. 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 to above, see
                  "Description of Permitted Investments and Risk Factors" and
                  the Statement of Additional Information.     
 
INVESTMENT LIMITATIONS _________________________________________________________
                     
                  The investment objective and investment limitations are
                  fundamental policies of the 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.     
 
                                                                    6
<PAGE>
 
                     
                     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 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.

                  .03%, respectively, of their relative net assets.     
 
                                                                    8

DISTRIBUTION ___________________________________________________________________
                     
                  SEI Financial Services Company (the "Distributor"), a
                  wholly-owned subsidiary of SEI, serves as each Portfolio's
                  distributor pursuant to a distribution agreement (the
                  "Distribution Agreement") with the Trust. Each Class of the
                  Trust has adopted a distribution plan (the "Class A Plan"
                  and "Class D Plan," and, collectively, the "Plans") pursuant
                  to Rule 12b-1 under the Investment Company Act of 1940 (the
                  "1940 Act").     
                     
                     The Class A Plan provides for reimbursement for expenses
                  incurred by the Distributor, provided those expenses are
                  permissible as to both type and amount under a budget
                  adopted by the Board of Trustees, including those who are
                  not interested persons and have no financial interest in the
                  Plan or any related agreement ("Qualified Trustees").
                  Pursuant to state law, the Distributor has voluntarily
                  agreed to limit the distribution-related expenses of the
                  Class A shares of each Portfolio to .25%. Currently, the
                  budget (shown here as a percentage of average daily net
                  assets) for each Portfolio is set at an annual rate of .04%.
                         
                     Distribution-related expenses reimbursable to the
                  Distributor under the budget include those related to the
                  costs of the printing of reports, prospectuses, notices and
                  similar materials for persons other than current
                  shareholders, federal and state securities law registration
                  and the cost of complying with such laws in the distribution
                  of the Trust's shares, advertising expenses and promotional
                  and sales expenses including expenses for travel,
                  communication and compensation and benefits for sales
                  personnel. Distribution expenses not attributable to a
                  specific Portfolio are allocated among each of the
                  Portfolios of the Trust on the basis of their average net
                  assets. The Trust is not obligated to reimburse the
                  Distributor for any expenditures in excess of the approved
                  budget.     
                     
                     It is possible that an institution may offer different
                  classes of shares to its customers and thus receive
                  different compensation with respect to different classes.
                  These financial institutions may also charge separate fees
                  to their customers.     
                     
                     The Trust may execute brokerage or other agency
                  transactions through the Distributor for which the
                  Distributor may receive compensation.     
                     
                     The Distributor may, from time to time in its sole
                  discretion, institute one or more promotional incentive
                  programs, which will be paid for by the Distributor from the
                  sales charge it receives or from any other source available
                  to it. 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 shares of the Portfolios, and also will be
                  offered uniformly to all dealers, predicated upon the amount
                  of shares of the Portfolios sold by such dealer.     
 
 
                                                                    9

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 restricting wire transfers.     
                     
                     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 value of the Portfolio's
                  investments and other assets, less any liabilities, by the
                  total 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     
 
                                                                    10

                  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.     
                     
                     For each Portfolio, the performance of the Class A shares
                  will normally be higher than the performance of the Class D
                  shares of that 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.     
 
                                                                    11
<PAGE>
 
 
                     
Tax Status of     Each Portfolio is treated as a separate entity for federal
the Portfolios    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 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     Each Portfolio distributes substantially all of its net
Distributions     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.     
                         
                                                                    12

                     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   The management and affairs of the Trust are supervised by
Trust             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       Shareholder inquiries should be directed to the Manager, SEI
Inquiries         Financial Management Corporation, 680 East Swedesford Road,
                  Wayne, Pennsylvania 19087-1658.     
                     
Dividends         The dividends of Class A shares will normally be higher than
                  on Class D shares of each Portfolio because of the
                  additional distribution and transfer agent expenses charged
                  to Class D shares.     
                     
                     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     
 
                                                                    13

                  excess of net long-term capital gain over net short-term
                  capital loss) realized, if any, are distributed at least
                  annually.

                  serves as custodian of the Trust's assets and as wire agent
                  of the Trust. The Custodian holds cash, securities and other

DESCRIPTION OF PERMITTED INVESTMENTS AND RISK FACTORS __________________________
                     
                  The following is a description of certain of the permitted
                  investments for the 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 or securities of U.S. and London
                  branches of foreign banks. 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,     
                            
                                                                    14

                  seizure of foreign deposits, currency controls, interest
                  limitations or other governmental restrictions which might
                  affect payment of principal or interest. Additionally, there
                  may be less public information available about foreign banks
                  and their branches. Foreign branches of foreign banks are
                  not regulated by U.S. banking authorities and generally are
                  not bound by accounting, auditing and financial reporting
                  standards comparable to U.S. banks. However, the Adviser
                  attempts to minimize these risks by investing only in those
                  instruments which satisfy the high quality and maturity
                  restrictions applicable to a Portfolio.     
                     
Illiquid          Illiquid securities are securities which cannot be sold or
Securities        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.     
                     
Repurchase        Repurchase agreements are agreements by which a Portfolio
Agreements        obtains a security and simultaneously commits to return the
                  security to the seller at an agreed upon price on an agreed
                  upon date. The custodian will hold the security as
                  collateral for the repurchase agreement. 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 or if the
                  Portfolio realizes a loss on the sale of the collateral. 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        Restricted Securities are securities that may not be sold
Securities        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   Certain federal agencies, such as the Government National
Agency            Mortgage Association ("GNMA"), have been established as
Obligations       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, its 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     U.S. Treasury obligations consist of bills, notes and bonds
Obligations       issued by the U.S. Treasury and separately traded interest
                  and principal component parts of such obligations that are
                      
                                                                    15

                  transferable through the federal book-entry system known as
                  Separately Traded Registered Interest and Principal
                  Securities ("STRIPS").
                     
                     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      Certain of the obligations purchased by a Portfolio may
Floating Rate     carry variable or floating rates of interest and may involve
Instruments       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   When-issued or delayed delivery transactions involve the
Delayed           purchase of an instrument with payment and delivery taking
Delivery          place in the future. Delivery of and payment for these
Securities        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.
                      
                                                                    16

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 contractually to waive a portion of its fee in order
  to limit total operating expenses for Class D shares of the Portfolio to not
  more than .84% of its average daily net assets. Absent these contractual
  provisions, management/advisory fees, 12b-1 fees and total operating expenses
  as a percentage of net assets, respectively, would have been .45%, .29% and
  .93% for the Treasury Securities Portfolio. Additional information may be
  found under "The Manager and Shareholder Servicing Agent," "The Adviser" and
  "Distribution."     
   
3 The 12b-1 fee shown reflects the Portfolio's current 12b-1 budget for
  reimbursement of expenses. The maximum 12b-1 fee payable by Class D shares
  for the Portfolio is .55%.

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 is to assist the investor in understanding the various costs and
expenses that may be directly or indirectly borne by investors in Class D
shares of the Portfolio. A person who purchases shares through an account with
a financial institution may be charged separate fees by that institution. 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 distribution costs. Additional information may be found under "The
Manager and Shareholder Servicing Agent," "The Adviser" and "Distribution."
Long-term shareholders may pay more than the economic equivalent of the maximum
front-end sales charge otherwise permitted by the Rules of Fair Practice of the
National Association of Securities Dealers, Inc. (the "NASD").

Exchange?        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

                 terminate the exchange privilege, upon 60 days' notice. The
                 Trust also reserves the right to deny an exchange request

                         INVESTMENT
                         OBJECTIVES AND
                         POLICIES?
    
 The Portfolio's investment objective is a statement of what it seeks to
 achieve. It is important to make sure that the investment objective matches
 your own financial needs and circumstances. The investment policies section
 spells out the types of securities in which the Portfolio invests.     
 ................................................................................

   
INVESTMENT OBJECTIVE AND POLICIES _________________________________________     
 
TREASURY         The investment objective of the Treasury Securities 
SECURITIES       Portfolio is to preserve principal value and maintain 
PORTFOLIO        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. In addition, the Portfolio may
                 only invest in securities (other than U.S. Government
                 Securities) rated in one of the two highest categories for
                 short-term securities by at least two nationally recognized
                 statistical rating organizations ("NRSROs") (or by one NRSRO
                 if only one NRSRO has rated the security), or, if unrated,
                 determined by the Adviser (in accordance with procedures
                 adopted by the Trust's Board of Trustees) to be of equivalent
                 quality to rated securities in which the Portfolio may
                 invest. Purchases of unrated securities and securities rated
                 by only one NRSRO 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, 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. The
                 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 limited to the greater of 1% of
                 the Portfolio's total assets or $1 million.     
                        
                    
                    The Portfolio may purchase securities on a when-issued or
                 delayed delivery basis.     
 
                                                                 9

                  permitted investments, see "Description of Permitted
                  Investments and Risk Factors" and the Statement of
                  Additional Information.     
 
INVESTMENT LIMITATIONS _________________________________________________________
                     
                  The investment objective and investment limitations are
                  fundamental policies of the Portfolio. Fundamental policies
                  cannot be changed with respect to the Portfolio without the
                  consent of the holders of a majority of the Trust's or the
                  Portfolio's outstanding shares. It is a fundamental policy
                  of the Portfolio to use its best efforts to maintain a
                  constant net asset value of $1.00 per share.     
                     
                  The Portfolio may not:     
                     
                  1. Purchase securities of any issuer (except securities
                     issued or guaranteed by the U.S. Government, its agencies
                     or instrumentalities and any securities guaranteed
                     thereby) if as a result more than 5% of 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 Portfolio may invest
                     up to 25% of its total assets without regard to this
                     restriction as permitted by Rule 2a-7.     
                     
                  2. Purchase any securities which would cause more than 25%
                     of the total assets of the Portfolio based on 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.     
                     
                  3. Borrow money except for temporary or emergency purposes
                     and then only in an amount not exceeding 10% of the value
                     of the total assets of the Portfolio. 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
                  Information.
 
                                                                    10

                  a Massachusetts general partnership, of which the following
                  persons are managing partners: Robert W. Doran, Duncan M.
                  McFarland and John B. Neff.
                     
                     John C. Keogh, Senior Vice President of the Adviser,
                  serves as portfolio manager to the Portfolio. He has been an
                  investment professional with the Adviser since 1983, and has
                  served as portfolio manager to the Treasury Securities
                  Portfolio since July 1994. Prior to that date, he assisted
                  the portfolio manager in the management of the Portfolio.
                      
                      
                     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 Portfolio
                  up to $500 million, and .02% of such 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, 1995, the
                  Treasury Securities Portfolio paid advisory fees, after fee
                  waivers, of .03% of its relative net assets.     
                         
DISTRIBUTION ___________________________________________________________________
       
                    
                  SEI Financial Services Company (the "Distributor"), a
                  wholly-owned subsidiary of SEI, serves as each Portfolio's
                  distributor pursuant to a distribution agreement (the
                  "Distribution Agreement") with the Trust. Each Class of the
                  Trust has adopted a distribution plan (the "Class A Plan"
                  and "Class D Plan," and, collectively, the "Plans") pursuant
                  to Rule 12b-1 under the Investment Company Act of 1940 (the
                  "1940 Act").     
                     
                     The Class D Plan provides for reimbursement for expenses
                  incurred by the Distributor, in an amount not to exceed .30%
                  of the average daily net assets of each Portfolio on an
                  annualized basis, and provided those expenses are
                  permissible as to both type and amount under a budget
                  adopted by the Board of Trustees, including those who are
                  not interested persons and have no financial interest in the
                  Plan or any related agreement ("Qualified Trustees").
                  Currently, the budget (shown here as a percentage of average
                  daily net assets) for each Portfolio is set at an annual
                  rate of .04%.     
                     
                     Distribution-related expenses reimbursable to the
                  Distributor under the budget include those related to the
                  costs of the printing of reports, prospectuses, notices and
                  similar materials for persons other than current
                  shareholders, advertising expenses and promotional and sales
                  expenses including expenses for travel, communication and
                  compensation and benefits for sales personnel. Distribution
                  expenses not attributable to a specific portfolio of the
                  Trust are allocated among each of the portfolios of the
                  Trust based on the basis of their relative average net
                  assets. The Trust is not obligated to reimburse the
                  Distributor for any expenditures in excess of the approved
                  budget.     
                     
                     The Class D Plan, in addition to providing for the
                  reimbursement payments described above, provides for
                  payments to the Distributor at an annual rate of .25% of
                  each Portfolio's average daily net assets attributable to
                  Class D shares. This additional 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     
 
                                                                    12

                  receives during any year may therefore be higher or lower
                  than its actual expenses. These additional 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 additional 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 the
                  sales charge it receives or from any other source available
                  to it. 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 shares of the Portfolios, and also will be
                  offered uniformly to all dealers, predicated upon the amount
                  of shares of the Portfolios sold by such dealer.     
                         
       
PERFORMANCE ____________________________________________________________________
       
                    
                  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 assumed to be reinvested. The "effective
                  yield" will be slightly higher than the "current yield"
                  because of the compounding effect of this assumed
                  reinvestment.     
 
                                                                    13

[SYMBOL APPEARS HERE]    DISTRIBUTIONS
 
 The Portfolio distributes income dividends and capital gains. Income dividends
 represent the earnings from the Portfolio's investments; capital gains dis-
 tributions occur when investments in the Portfolio are sold for more than the
 original purchase price.

                    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 is treated as a separate entity for federal 
the Portfolio:   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    The Portfolio will distribute substantially all of its net 
Distributions:   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     
 
                                                                 14
<PAGE>
 
                     
                  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.     
                     
                     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.

                 order.                                                         
                                                                                
Maintaining a    Due to the relatively high cost of handling small            
Minimum          investments, the Portfolio reserves the right to redeem, at  
Account          net asset value, the shares of any shareholder if, because of
Balance          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.     
 
                                                                 16

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       The net asset value per share of the Portfolio is determined
Asset Value is    by dividing the total market value of its investments and  
Determined        other assets, less any liabilities, by the total number of 
                  outstanding shares of that 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 charged to each class and the incremental transfer    
                  agent fees charged to Class D shares.                       
                  
Signature         The Transfer Agent may require that the signatures on the
Guarantees        written request be guaranteed. You should be able to obtain
                  a signature guarantee from a bank, broker, dealer, certain
                  credit unions, securities exchange or association, clearing
                  agency or savings association. Notaries public cannot
                  guarantee signatures. The signature guarantee requirement
                  will be waived if all of the following conditions apply: (1)
                  the redemption is for not more than $5,000 worth of shares,
                  (2) the redemption check is payable to the shareholder(s) of
                  record, and (3) the redemption check is mailed to the
                  shareholder(s) at his or her address of record. The Trust
                  and the Transfer Agent reserve the right to amend these
                  requirements without notice.
                                                                             
Telephone/Wire    Redemption orders may be placed by telephone. Neither the  
Instructions      Trust nor the Transfer Agent will be responsible for any   
                  loss, liability, cost or expense for acting upon wire      
                  instructions or upon telephone instructions that it        
                  reasonably believes to be genuine. The Trust and the       
                  Transfer Agent will each employ reasonable procedures to   
                  confirm that instructions communicated by telephone are    
                  genuine, including requiring a form of personal            
                  identification prior to acting upon instructions received by
                  telephone and recording telephone instructions. If market  
                  conditions are extraordinarily active, or other            
                  extraordinary circumstances exist, and you experience      
                  difficulties placing redemption orders by telephone and may

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. Shareholders may purchase shares
                  in Portfolios through two separate classes: Class A and
                  Class D, which provide for variation in distribution and
                  transfer agent costs, voting rights, dividends, and the
                  imposition of a sales charge on the Class D shares. 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 portfolios: Government
                  Securities Portfolio, Institutional Cash Portfolio, Prime
                  Obligation Portfolio, and Money Market Portfolio. Additional
                  information pertaining to the Trust may be obtained by
                  writing to SEI Financial Management Corporation, 680 East
                  Swedesford Road, Wayne, Pennsylvania 19087-1658, or by
                  calling 1-800-437-6016. All consideration received by the
                  Trust 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
                  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   The management and affairs of the Trust are supervised by
Trust             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.     
 
                                                                    18

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            
                  The dividends of Class D shares will normally be lower than
                  on Class A shares of the Portfolio because of the additional
                  distribution and transfer agent expenses charged to Class D
                  shares. 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.

                  of the Trust. The Custodian holds cash, securities and other

DESCRIPTION OF PERMITTED INVESTMENTS AND RISK FACTORS __________________________
                     
                  The following is a description of certain of the permitted
                  investments for the Portfolio, and the associated risk
                  factors:     
                  
Repurchase        Repurchase agreements are agreements by which a Portfolio
Agreements        obtains a security and simultaneously commits to return the
                  security to the seller at an agreed upon price on an agreed
                  upon date. The custodian will hold the security as
                  collateral for the repurchase agreement. The Portfolio bears
                  a risk of loss in the event the other party defaults on its
                      
                                                                    19

                  obligations and the Portfolio is delayed or prevented from
                  exercising its right to dispose of the collateral or if the
                  Portfolio realizes a loss on the sale of the collateral. 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     U.S. Treasury Obligations consist of bills, notes and bonds
Obligations       issued by the U.S. Treasury and separately traded interest
                  and principal component parts of such obligations that are
                  transferable through the federal book-entry system known as
                  Separately Traded Registered Interest and Principal
                  Securities ("STRIPS").     
                     
                  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   When-issued or delayed delivery transactions involve the
Delayed           purchase of an instrument with payment and delivery taking
Delivery          place in the future. Delivery of and payment for these
Securities        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 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.
    
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.


                                      S-3
<PAGE>
 
    
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
stable, margin and principal is secure.  While the various protective elements
are likely to change, such changes as can be visualized are most unlikely to
impair the fundamentally strong position of such issues.  Bonds rated Aa 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 rated 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 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 U.S. dollar
denominated obligations of 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       

                                      S-4
<PAGE>
 
    
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.      
    
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.      
    
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 ("WMC" or 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, CoreStates Bank, N.A. (the "Custodian") or its agent must
take possession of the underlying collateral.  However, if the seller defaults,
the Portfolios could realize a loss on the sale of the underlying security to
the extent the proceeds of the sale are less than the resale price.  In
addition, even though the Bankruptcy Code provides protection for most
repurchase agreements, if the seller should be involved in bankruptcy or
insolvency proceedings, the Portfolios may incur 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 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       

                                      S-5
<PAGE>
 
    
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, 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.,
Government National Mortgage Association), 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., Federal National Mortgage Association).
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 AND SHAREHOLDER SERVICING AGENT
    
The Management Agreement, dated October 31, 1986, provides that SEI Financial
Management Corporation (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 wholly-owned subsidiary of SEI Corporation ("SEI"), was organized
as a Delaware corporation in 1969, and has its principal business offices at 680
East Swedesford Road, Wayne, Pennsylvania 19087-1658.  Alfred P. West, Jr.,
Henry H. Greer and Carmen V. Romeo constitute the Board of Directors of the
Manager.  Mr. West serves as the Chairman of the Board of Directors, President
and Chief Executive Officer of SEI.  Mr. Greer serves as Director, President and
Chief Operating Officer of SEI.  SEI and its subsidiaries 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 also serves as manager/administrator to these other
mutual funds: SEI Daily Income Trust; SEI Tax Exempt Trust; SEI Index Funds; SEI
Institutional Managed Trust; SEI International Trust; Stepstone Funds; The
Compass Capital Group; FFB Lexicon Funds; The Advisors' Inner Circle Fund; The
Pillar Funds; CUFUND; STI Classic Funds; CoreFunds, Inc.; First American Funds,

Morgan Grenfell Investment Trust; Inventor Funds; Insurance Investment Products
Trust; Bishop Street Funds; Conestoga Family of Funds; The Achievement Funds
Trust; CrestFunds, Inc.(C); and STI Classic Variable Trust.      
    
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, 1993, 1994 and 1995, the Portfolios paid
fees to the Manager as follows:

THE ADVISER
    
The Trust and Wellington Management Company ("WMC") 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
the Adviser, or by the Adviser on 90 days' written notice to the Trust.

WMC, Adviser to the Portfolios, is entitled to a fee for its investment advisory
services, which is calculated daily and paid monthly at the following annual
rates:  .075% of the 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.      
    
For the fiscal years ended June 30, 1993, 1994 and 1995 the Portfolios paid WMC

DISTRIBUTION
    
The Trust has adopted a Distribution Agreement for the Portfolios dated November
29, 1982.  The Trust has also adopted a Class A Distribution Plan (the "Class A
Plan") and a Class D Distribution Plan (the "Class D Plan" and, together with
the Class A Plan, the "Plans") for the Portfolios 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 Plans
and the Distribution Agreement are in the best interests of the Shareholders.
Continuance of the Plans must be approved annually by a majority of the Trustees
of the Trust, and by a majority of the trustees who are not "interested persons"
of the Trust as that term is defined in the 1940 Act, and who have no direct or
indirect financial interest in the operation of a Distribution Plan or in any
agreements related thereto ("Qualified Trustees").  The Plans require that
quarterly written reports of amounts spent under the Plans and the purposes of
such expenditures be furnished to and reviewed by the Trustees.  The Plans may
not be amended to increase materially the amount which may be spent thereunder
without approval by a majority of the outstanding shares of the Portfolio
affected.  All material amendments of the Plans will require approval by a
majority of the Trustees of the Trust and of the Qualified Trustees.      
    
For the fiscal year ended June 30, 1995, the Portfolios incurred the following
distribution expenses:

*Messrs. Nesher and Doran are Trustees who may be deemed to be "interested
 persons" of the Trust as the term is defined in the 1940 Act.      
    
**Retired as of December, 1994.      


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.


                                     S-11
<PAGE>
 
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.

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      
    
1.   The Government Securities and Prime Obligations Portfolios may not purchase
     obligations with remaining maturities of more than 365 days and must
     maintain an average dollar-weighted portfolio maturity of more than 90
     days.      

    
ADDITIONAL RESTRICTIONS      
    
The following are non-fundamental investment limitations that are currently
required by one or more states in which the Trust sells shares of the
Portfolios.  These limitations are in addition to, and in some cases more
restrictive than, the fundamental and non-fundamental investment limitations
listed above.  A limitation may be changed or eliminated without shareholder
approval if the relevant state changes or eliminates its policy regarding such
investment restriction.  As long as a Portfolio's shares are registered for sale
in such states, it may not:      
    
1.   Invest more than 10% of its total assets in illiquid securities, including
     securities which are not readily marketable or are restricted.      
    
2.   Invest more than 15% of its assets in restricted securities.  For purposes
     of this limitation, securities exempted from registration under the 1933
     Act, including Section 4(2) commercial paper, are considered to be
     restricted securities.      


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, 1995 the Portfolios' yield and effective
yield were as follows:

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 comparable quality in accordance with
guidelines established by the Trustees.  The Trustees must approve or ratify the
purchase of any unrated securities or securities rated by only one rating
organization.  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      


                                     S-14
<PAGE>
 
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 be 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 in order to realize the difference between the sales charge imposed
under the Letter of Intent and the sales charge that would have otherwise been
imposed.      

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
     

                                     S-15
<PAGE>
 
    
fund is considered a "wash sale" and results in the inability to recognize
currently all or a portion of a loss realized on the original redemption for
federal income tax purposes.  The investor must notify the Transfer Agent at the
time the trade is placed that the transaction is a reinvestment.      
    
Exchange Privilege: 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 Daily Income 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.
    
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      


                                     S-16
<PAGE>
 
    
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.



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.


                                     S-17
<PAGE>
 
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.
    
For the Trust's fiscal years ended June 30, 1993, 1994 and 1995, 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 October 5, 1995, 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.

NOTES TO FINANCIAL STATEMENTS
- -------------------------------------------------------------------------
SEI Liquid Asset Trust--June 30, 1995
1. ORGANIZATION
 
SEI Liquid Asset Trust (the "Trust") was organized as a Massachusetts business
trust under a Declaration of Trust dated July 20, 1981.
  The Trust is registered under the Investment Company Act of 1940, as amended,
as a diversified, open-end management investment company with five portfolios:
the Treasury Securities Portfolio, the Government Securities Portfolio, the
Prime Obligation Portfolio, the Institutional Cash Portfolio and the Money Mar-
ket Portfolio (the "Portfolios"). The Trust is registered to offer Class A
shares of the portfolios and Class D (formerly the ProVantage Funds) shares of
the Treasury Securities Portfolio and the Prime Obligation Portfolio. The as-
sets of each Portfolio are segregated and a shareholder's interest is limited
to the Portfolio in which shares are held. As of June 30, 1995 the Money Market
Portfolio had not commenced operations.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
The following is a summary of significant accounting policies followed by the
Trust.
  Security Valuation--Investment securities are stated at amortized cost, which
approximates market value. Under this valuation method, purchase discounts and
premiums are accreted and amortized ratably to maturity and are included in in-
terest income.
  Federal Income Taxes--It is each Portfolio's intention to continue to qualify
as a regulated investment company and distribute all of its taxable income. Ac-
cordingly, no provision for Federal income taxes is required.
  Repurchase Agreements--Securities pledged as collateral for Repurchase Agree-
ments are held by the Portfolio's custodian bank until maturity of the Repur-
chase Agreement. Provisions of the Agreement and procedures adopted by the Man-
ager of the Trust ensure that the market value of the collateral, including ac-
crued interest thereon, is sufficient in the event of default by the
counterparty.
  The Trust also invests in tri-party repurchase agreements. Securities held as
collateral for tri-party repurchase agreements are maintained in a segregated
account by the broker's custodian bank until maturity of the repurchase agree-
ment. Provisions of the agreements ensure that the market value of the collat-
eral, including accrued interest thereon, is sufficient in the event of de-
fault.
  If the counterparty defaults and the value of the collateral declines or if
the counterparty enters an insolvency proceeding, realization of the collateral
by the Trust may be delayed or limited.
  Discount and Premium Amortization--All amortization is calculated using the
effective interest method over the holding period of the security. Amortization
of premiums and discounts is currently included in interest income.
  Expenses--Expenses of the Trust which are not directly associated to a spe-
cific Portfolio are allocated on the basis of relative net asset value of the
affected Portfolios.
  Classes--Expenses of a class of shares of beneficial interest are borne by
that class. Income, expenses and realized gains/losses are allocated to the re-
spective classes on the basis of relative daily net assets.
  Other--Security transactions are accounted for on the date the securities are
purchased or sold. Costs used in determining realized gains and losses on the
sale of investment securities are those of the specific securities sold. Dis-
tributions from net investment income are declared on a daily basis and are
payable on the first business day of the following month. Any net realized cap-
ital gains of the Portfolios are distributed to the shareholders of the af-
fected Portfolios annually.
 
3. MANAGEMENT, INVESTMENT ADVISORY AND DISTRIBUTION AGREEMENTS
 
SEI Financial Management Corporation (the "Manager") provided management, ad-
ministrative and shareholder services to the Trust for an annual fee, which is
calculated daily and paid monthly, of .42% of the average daily net assets of
each Portfolio with the exception of the Institutional Cash Portfolio for which
the fee is calculated at an annual rate of .36%. The Manager has agreed to bear
certain expenses of the Trust so that the total expenses do not exceed .44% of
average daily net assets annually. For the fiscal year ended June 30, 1995 the
manage-

ment fee was $10,636,000 of which $2,332,000 was waived by the Manager in ac-
cordance with the expense limitation discussed above.
  In addition, the Trust and the Manager have entered into a separate Transfer
Agent Agreement with respect to Class D shares under which DST Systems, Inc. is
entitled to a fee of .15% of the average daily net assets of Class D plus out-
of-pocket costs.
  Wellington Management Company serves as the Investment Adviser of the Trust.
For its services, the Investment Adviser receives an annual fee equal to .075%
of the Trust's average daily net asset value up to $500 million and .02% of
such net asset value in excess of $500 million. At June 30, 1995, the Invest-
ment Adviser was a holder of beneficial interest in the Trust. The fees of the
Investment Adviser are paid monthly.
  SEI Financial Services Company ("SFS") acts as the distributor of the shares
of the Trust under a Distribution Agreement and Distribution Plans which pro-
vide for the Trust to reimburse SFS for its distribution expenses. Reimburse-
ment for expenses incurred by SFS may not exceed .30% of a Portfolio's average
daily net assets. Distribution expenses include, among other items, the compen-
sation and benefits of sales personnel incurred by SFS in connection with the
promotion and sale of shares. Distribution expenses not attributable to a spe-
cific Portfolio are allocated among the Portfolios on the basis of their rela-
tive average daily net assets.
  In addition, the Treasury Securities Portfolio and the Prime Obligation Port-
folio have registered an additional class of shares, Class D shares, for which
a separate distribution plan has been adopted. The Class D Distribution Plan
(the "Class D" Plan) provides for additional payments to the distributor of
 .25% of each of the Class D shares average daily net assets. As of the fiscal
year end, SFS is taking a fee under the Class D Plan of only .20% of each of
the Class D average daily net assets.
 
4. TRANSACTIONS WITH AFFILIATES
 
  Certain officers and/or Trustees of the Trust are also officers and/or Direc-
tors of the Manager or SFS. Compensation of officers and affiliated Trustees of
the Trust is paid by the Manager and/or SFS.
  CoreStates N.A., which is a Trust shareholder, acts as Custodian and Wire
Agent for the Trust.
 
5. CAPITAL LOSS CARRYOVERS

REPORT OF INDEPENDENT ACCOUNTANTS
- --------------------------------------------------------------------------------
To the Board of Trustees and Shareholders of 
SEI Liquid Asset Trust:
 
In our opinion, the accompanying statement of net assets and statement of
assets and liabilities, and the related statements of operations and of changes
in net assets and the financial highlights present fairly, in all material
respects, the financial position of the Treasury Securities Portfolio, the
Government Securities Portfolio, the Prime Obligation Portfolio, the
Institutional Cash Portfolio and the Money Market Portfolio (constituting SEI
Liquid Asset Trust, hereafter referred to as the "Trust") at June 30, 1995, the
results of each of their operations, the changes in each of their net assets
and the financial highlights for each of the respective periods presented, in
conformity with generally accepted accounting principles. These financial
statements and financial highlights (hereafter referred to as "financial
statements") are the responsibility of the Trust's management; our
responsibility is to express an opinion on these financial statements based on
our audits. We conducted our audits of these financial statements in accordance
with generally accepted auditing standards which require that we plan and
perform the audit to obtain reasonable assurance about whether the financial
statements are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements, assessing the accounting principles used and significant estimates
made by management, and evaluating the overall financial statement
presentation. We believe that our audits, which included confirmation of
securities at June 30, 1995, by correspondence with the custodian, provide a
reasonable basis for the opinion expressed above.

  Item 27. Indemnification:
    
     Article VIII of the Agreement and Declaration of Trust filed as Exhibit 1
  to the Registration Statement is filed herewith. Insofar as indemnification
  for liabilities arising under the     

                                      C-2
<PAGE>
 
  Securities Act of 1933 may be permitted to trustees, directors, officers and
  controlling persons of the Registrant by the Registrant pursuant to the
  Declaration of Trust or otherwise, the Registrant is aware that in the opinion
  of the Securities and Exchange Commission, such indemnification is against
  public policy as expressed in the Act and, therefore, is unenforceable. In the
  event that a claim for indemnification against such liabilities (other than
  the payment by the Registrant of expenses incurred or paid by trustees,
  directors, officers or controlling persons of the Registrant in connection
  with the successful defense of any act, suit or proceeding) is asserted by
  such trustees, directors, officers or controlling persons in connection with
  the shares being registered, the Registrant will, unless in the opinion of its
  counsel the matter has been settled by controlling precedent, submit to a
  court of appropriate jurisdiction the question whether such indemnification by
  it is against public policy as expressed in the Act and will be governed by
  the final adjudication of such issues.

  Item 28.  Business and Other Connections of Investment Adviser:
      
  The list required by this Item 28 of officers and partners of Wellington
  Management Company, together with information as to any other business,
  profession, vocation or employment of a substantial nature engaged in by such
  officers and partners during the past two years, is incorporated by reference
  to Schedules A and D of Form ADV, filed by Wellington Management Company
  pursuant to the Investment Advisers Act of 1940 (SEC File No. 801-15908).

      of the Registrant also acts as a principal underwriter, distributor or

<PAGE>
 
                                  ARTICLE III

                                    Shares
                                    ------

Division of Beneficial Interest
- -------------------------------

     Section 1.  The Shares of the Trust shall be issued in one or more series 
     ---------
as the Trustees may, without shareholder approval, authorize. Each series shall 
be preferred over all other series in respect of the assets allocated to that 
series. The beneficial interest in each series shall at all times be divided 
into Shares, without par value, each of which shall represent an equal 
proportionate interest in the series with each other Share of the same series, 
none having priority or preference over another. The number of Shares authorized
shall be unlimited, and the Shares so authorized may be represented in part by 
fractional shares. The Trustees may from time to time divide or combine the 
Shares of any series into a greater or lesser number without thereby changing 
the proportionate beneficial interests in the series.

Ownership of Shares
- --------------------

     Section 2.  The ownership of Shares shall be recorded on the books of 
     ---------
the Trust or its transfer or similar agent. No certificates certifying the 
ownership of Shares shall be issued except as the Trustees may otherwise 
determine from time to time. The Trustees may make such rules as they consider 
appropriate for the issuance of Share certificates, the transfer of Shares and 
similar matters. The record books of the Trust as kept by the Trust or any 
transfer or similar agent of the Trust, as the case may be, shall be conclusive 
as to who are the Shareholders of each series and as to the number of Shares of 
each series held from time to time by each Shareholder.

Investments in the Trust; Assets of the Series
- ----------------------------------------------

     Section 3.  The Trustees may accept investments in the Trust from such 
     ---------
persons and on such terms and, subject to any requirements of law, for such 
consideration, which may consist of cash or tangible or intangible property or a
combination thereof, as they may from time to time authorize.

     All consideration received by the Trust for the issue or sale of Shares of 
each series, together with all income, earnings, profits, and proceeds thereof, 
including any proceeds derived from the sale, exchange or liquidation thereof, 
and any funds or payments derived from any reinvestment of such proceeds in 
whatever form the same may be, shall irrevocably belong to the series of Shares
with respect to which the same were received by the Trust for all purposes, 
subject only to the rights of creditors, and shall be so handled upon the books 
of account of the Trust and are herein referred to as "assets of" such series.

                                     - 3 -
<PAGE>
 
No Preemptive Rights
- --------------------

     Section 4.  Shareholders shall have no preemptive or other right to 
     ---------
receive, purchase or subscribe for any additional Shares or other securities 
issued by the Trust.

Status of Shares and Limitation of Personal Liability
- -----------------------------------------------------

     Section 5.  Shares shall be deemed to be personal property giving only the 
     ---------
rights provided in this instrument. Every shareholder by virtue of having become
a Shareholder shall be held to have expressly assented and agreed to the terms 
of the Declaration of Trust and to have become a party thereto. The death of a 
Shareholder during the continuance of the Trust shall not operate to terminate 
the same nor entitle the representative of any deceased Shareholder to an 
accounting or to take any action in court or elsewhere against the Trust or 
the Trustees, but only to the rights of said decedent under this Trust. 
Ownership of Shares shall not entitle the Shareholder to any title in or to the 
whole or any part of the Trust property or right to call for a partition or 
division of the same or for an accounting, nor shall the ownership of Shares 
constitute the Shareholders partners. Neither the Trust nor the Trustees, nor 
any officer, employee or agent of the Trust shall have any power to bind 
personally any Shareholder, nor except as specifically provided herein to call 
upon any Shareholder for the payment of any sum of money or assessment 
whatsoever other than such as the Shareholder may at any time personally agree 
to pay.

                                  ARTICLE IV

                                 The Trustees
                                 ------------

Election 
- --------

     Section 1.  The number of Trustees shall be fixed by the Trustees, except 
     ---------
that there shall be not less than three nor more than fifteen Trustees. Any 
vacancies occurring in the Board of Trustees may be filled by the Trustees if, 
immediately after filling any such vacancy, at least two-thirds of the Trustees 
then holding office would have been elected to such office by the Shareholders. 
In the event that at any time less than a majority of the Trustees then holding

                                   ARTICLE V

                   Shareholder's Voting Powers and Meetings
                   ----------------------------------------

Voting Powers
- -------------

     Section 1.  The Shareholders shall have power to vote only (i) for the 
     ---------
election or removal of Trustees as provided in Article IV, Section 1, (ii) with 
respect to any investment advisor or manager as provided in Article IV, 
Section 7, (iii) with respect to any termination of the Trust to the extent and 
as provided in Article IX, Section 4, (iv) with respect to any amendment of this
Declaration of Trust to the extent and as provided in Article IX, Section 7, (v)
to the same extent as the stockholders of a Massachusetts business corporation
as to

                                     - 9 -
<PAGE>
 
whether or not a court action proceeding or claim should or should not be 
brought or maintained derivatively or as a class action on behalf of the Trust 
or the Shareholders, and (vi) with respect to such additional matters relating 
to the Trust as may be required by law, this Declaration of Trust, the By-laws 
or any registration of the Trust with the Commission (or any successor agency 
or any state, or as the Trustees may consider necessary or desirable.

     Each whole Share shall be entitled to one vote as to any matter on which it
is entitled to vote and each fractional Share shall be entitled to a 
proportionate fractional vote. On any matter submitted to a vote of Shareholders
all Shares of the Trust then entitled to vote, irrespective of series, shall be 
voted in the aggregate and not by series, except (1) when required by the 1940 
Act, Shares shall be voted by individual series, in which event, unless 
otherwise required by the 1940 Act, a vote of Shareholders of all shares of the 
Trust, irrespective of series, shall not be required; and (2) when the Trustees 
have determined that the matter affects only the interests of one or more 
series, then only Shareholders of the such series shall be entitled to vote 
thereon. There shall be no cumulative voting in the election of Trustees. Shares
may be voted in person or by proxy.

     A proxy with respect to Shares held in the name of two or more persons 
shall be valid if executed by any one of them unless at or prior to the exercise
of the proxy the Trust receives a specific written notice to the contrary from 
any one of them. A proxy purporting to be executed by or on behalf of a 
Shareholder shall be deemed valid unless challenged at or prior to its exercise 
and the burden of proving invalidity shall rest on the challenger.

     Until Shares are issued, the Trustees may exercise all rights of 
Shareholders and may take any action required by-law, this Declaration of Trust 
or the By-Laws to be taken by Shareholders.

Voting Power and Meetings
- -------------------------

     Section 2.  Meetings of Shareholders of the Trust or of any series may be 
     ---------
called by the Trustees, or such other person or persons as may be specific in 
the By-Laws, and held from time to time for the purpose of taking action upon 
any matter requiring the vote or the authority of the Shareholders of the Trust 
or any series as herein provided or upon any other matter deemed by the Trustees
to be necessary or desirable. Meetings of Shareholders of the Trust or of any 
series shall be called by the Trustees or such other person or persons as may be
specified in the By-Laws upon written application by Shareholders holding at 
least 10% of the outstanding Shares of the Trust, if Shareholders 

                                    - 10 -
<PAGE>
 
of all series are required hereunder to vote in the aggregate and not by 
individual series at such meeting, or of any series, if Shareholders of such 
series are entitled hereunder to vote by individual series at such meeting, 
requesting that a meeting be called for a purpose requiring action by the 
Shareholders as provided herein or in the By-Laws. The Shareholders shall be 
entitled to at least seven days' written notice of any meeting of the 
Shareholders.

Quorum and Required Vote
- ------------------------

     Section 3.  A majority of the Shares entitled to vote shall be a quorum for
     ---------
the transaction of business at a Shareholders' meeting, except that where any 
provision of law or of this Declaration of Trust permits or requires that 
holders of any series shall vote as a series, then a majority of the aggregate 
number of Shares of that series entitled to vote shall be necessary to 
constitute a quorum for the transaction of business by that series. Any lesser 
number, however, shall be sufficient for adjournments. Any adjourned session or 
sessions may be held within a reasonable time after the date set for the 
original meeting without the necessity of further notice.

     Except when a larger vote is required by any provisions of this Declaration
of Trust or the By-Laws, a majority of the Shares voted on any matter shall 
decide such matter and a plurality shall elect a Trustee, provided that where 
any provision of law or of this Declaration of Trust permits or requires that 
the holders of any series shall vote as a series, then a majority of the Shares 
of that series voted on the matter shall decide that matter insofar as that 
series is concerned.

Action by Written Consent
- -------------------------

     Section 4.  Any action taken by Shareholders may be taken without a meeting
     ---------
if a majority of Shareholders entitled to vote on the matter (or such larger 
vote as shall be required by any provision of this Declaration of Trust or the 
By-Laws) consent to the action in writing and such written consents are filed 
with the records of the meetings of Shareholders. Such consent shall be treated 
for all purposes as a vote taken at a meeting of Shareholders.

Additional Provisions
- ---------------------

     Section 5.  The By-Laws may include further provisions for Shareholders' 
     ---------
votes and meetings and related matters.

                                  ARTICLE VI

                  Distributions, Redemptions and Repurchases,
                     and Determination of Net Asset Value
                  -------------------------------------------

Distributions
- -------------

     Section 1.  The Trustees may, but need not, each year distribute to the 
     ---------
Shareholders of each series such income and gains, accrued or realized, as 
the Trustees may determine, after providing for actual and accrued expenses and 
liabilities (including such reserves as the Trustees may establish) determined 
in accordance with good accounting practices. The Trustees shall have full 
discretion to determine which items shall be treated as income and which items 
as capital and their determination shall be binding upon the Shareholders. 
Distributions of each year's income of each series, if any be made, may be made 
in one or more payments, which shall be in Shares, in cash or otherwise and on a
date or dates determined by the Trustees. At any time and from time to time in 
their discretion, the Trustees may distribute to the Shareholders of any one or 
more series as of a record date or dates determined by the Trustees, in Shares, 
in cash or otherwise, all or part of any gains, realized on the sale or 
disposition of property of the Trust or otherwise, or all or part of any other 
principal of the Trust. Each distribution pursuant to this Section 1 shall be 
made ratably according to the number of Shares of the series held by the several
Shareholders on the applicable record date thereof, provided that no 
distributions need be made on Shares purchased pursuant to orders received, or 
for which payment is made, after such time or times as the Trustees may 
determine. Any such distribution paid in Shares will be paid at the net asset 
value thereof as determined in accordance with this Declaration of Trust.

Redemptions and Repurchases
- ---------------------------

     Section 2.  Any holder of Shares of the Trust may by presentation of a 
     ---------
written request, together with his certificates, if any, for such Shares, in
proper form for transfer, at the office of the Trust or the Manager or at a
principal office of a transfer or shareholder service agent appointed by the
Trust, redeem his Shares for the net asset value thereof determined and computed
in accordance with the provisions of this Section 2 and the provisions of
Section 5 of Article VI of this Declaration of Trust.

     Upon receipt by the Trust, the Manager or its transfer or shareholder 
service agent of such written request for redemption of Shares, such Shares 
shall be redeemed at the net asset value per share of the particular series next

                                    - 12 -
<PAGE>
 
determined after such Shares are tendered in proper form for transfer to the 
Trust or determined as of such other time fixed by the Trustees as may be 
permitted or required by the 1940 Act, provided that no such tender shall be 
required in the case of Shares for which a certificate or certificates have not 
been issued, and in such case such Shares shall be redeemed at the net asset 
value per share of the particular series next determined after such demand has 
been received or determined at such other time fixed by the Trustees as may be 
permitted or required by the 1940 Act.

     The obligation of the Trust to redeem its Shares of each series as set 
forth in this Section 2 shall be subject to the conditions that during any time 
of emergency, as hereinafter defined, such obligation may be suspended by the 
Trust by or under authority of the Trustees for such period or periods during 
such time of emergency as shall be determined by or under authority of the 
Trustees. If there is such a suspension, any Shareholder may withdraw any demand
for redemption and any tender of Shares which has been received by the Trust 
during any such period and any tender of Shares the applicable net asset value 
of which would but for such suspension be calculated as of a time during such 
period. Upon such withdrawal, the Trust shall return to the Shareholder the 
certificates therefor, if any. For the purposes of any such suspension "time of 
emergency" shall mean, either with respect of all Shares or any series of 
Shares, any period during which:

           a.  the New York Stock Exchange is closed other than for customary 
     weekend and holiday closing; or

           b.  the Trustees or authorized officers of the Trust shall have 
     determined, in compliance with any applicable rules and regulations of the 
     Securities and Exchange Commission, either that trading on the New York 
     Stock Exchange is restricted, or that an emergency exists as a result of 
     which (i) disposal by the Trust of securities owned by it is not reasonably
     practicable or (ii) it is not reasonably practicable for the Trust fairly 
     to determine the current value of its net assets; or

           c.  The suspension or postponement of such obligations is permitted 
     by order of the Securities and Exchange Commission.

     The Trust may also purchase, repurchase or redeem Shares in accordance with
such other methods, upon such other terms and subject to such other conditions 
as the Trustees may from time to time authorize at a price not exceeding the net
asset value of such Shares in effect when the purchase or repurchase or any 
contract to purchase or repurchase is made.

                                    - 13 -

Payment in Kind
- ---------------

     Section 3.  Subject to any generally applicable limitation imposed by the 
     ---------
Trustees, any payment on redemption, purchase or repurchase by the Trust of 
Shares may, if authorized by the Trustees, be made wholly or partly in kind, 
instead of in cash. Such payment in kind shall be made by distributing 
securities or other property, constituting, in the opinion of the Trustees, a 
fair representation of the various types of securities and other property then 
held by the series of Shares being redeemed purchased or repurchased (but not 
necessarily involving a portion of each of the series' holdings) and taken at 
their value used in determining the net asset value of the Shares in respect of 
which payment is made.

Additional Provisions Relating to Redemptions and Repurchases
- -------------------------------------------------------------

     Section 4.  The completion of redemption, purchase or repurchase of Shares 
     ---------
shall constitute a full discharge of the Trust and the Trustees with respect to 
such Shares and the Trustees may require that any certificate or certificates 
issued by the Trust to evidence the ownership of such Shares shall be 
surrendered to the Trustees for cancellation or notation.

Determination of Net Asset Value
- --------------------------------

     Section 5.  The term "net asset value" of the Shares of each series shall 
     ---------
mean: (i) the value of all the assets of such series; (ii) less total
liabilities of such series; (iii) divided by the number of Shares of such series
outstanding, in each case at the time of each determination. The "number of
Shares of such series outstanding" for the purposes of such computation shall be
exclusive of any Shares of such series to be redeemed, purchased or repurchased
by the Trust and not then redeemed, purchased or repurchased as to which the
price has been determined, but shall include Shares of such series presented for
redemption, purchase or repurchase by the Trust and not then redemmed, purchased
repurchased as to which the price has not been determined and Shares of such
series the sale of which has been confirmed. Any fractions involved in the
computation of net asset value per share shall be adjusted to the nearer cent
unless the Trustees shall determine to adjust such fraction of a cent.

     The Trustees, or any officer, or officers or agent of the Trust designated 
for the purpose by the Trustees shall determine the net asset value of the 
Shares of each series, and the Trustees shall fix the time as of which the net 
asset value of the Shares of each series shall be determined and shall fix the 
periods during which any such net asset value shall be effective as to sales, 
redemptions and repurchases of, and other transactions in, the Shares of such 
series, except as such times and periods of any such transaction may be fixed by
other provisions of this Declaration of Trust or by the By-Laws.

                                    - 14 -




<PAGE>
 
     In valuing the portfolio investments of any series for determination of net
asset value per share of such series, securities for which market quotations are
readily available shall be valued at prices which, in the opinion of the
Trustees or any officer, or officers or agent of the Trust designated for the
purpose by the Trustees, most nearly represent the market value of such
securities which may, but need not, be the most recent bid price obtained from
one or more of the market makers for such securities; other securities and
assets be valued at fair value as determined by or pursuant to the direction of
the Trustees. Notwithstanding the foregoing short-term debt obligations,
commercial paper, and repurchase agreements may be, but need not be, valued on
the basis of quoted yields for securities of comparable maturity, quality and
type, or on the basis of amortized cost. In the determination of net asset value
of any series, dividends receivable and accounts receivable for investments sold
and for Shares sold shall be stated at the amounts to be received therefor; and
income receivable accrued daily on bonds and notes owned shall be stated at the
amount to be received. Any other assets shall be stated at fair value as
determined by the Trustees or such officer, officers or agent pursuant to the
Trustees' authority, except that no value shall be assigned to good will,
furniture, lists, reports, statistics or other noncurrent assets other than real
estate. Liabilities of any series for accounts payable, for investments
purchased and for Shares tendered for redemption, purchase or repurchase by the
Trust and not then redeemed, purchased or repurchased as to which the price has
been determined shall be stated at the amounts payable therefor. In determining
net asset value of any series, the person or persons making such determination
on behalf of the Trust may include in liabilities such reserves, estimated
accrued expenses and contingencies as such person or persons may in its, his or
their best judgment deem fair and reasonable under the circumstances. Any income
dividends and gains distributions payable by the Trust shall be deducted as of
such time or times on the record date therefor as the Trustees shall determine.

     The manner of determining the net assets of any series or of determining 
the net asset value of the Shares of any series may from time to time be altered
as necessary or desirable in the judgment of the Trustees to conform to any 
other method prescribed or permitted by any applicable law or regulation or 
generally accepted accounting practice.

     Determinations in accordance with Section 5 made in good faith shall be 
binding on all parties concerned.

Maintenance of Constant Net Asset Value
- ---------------------------------------

     Section 6.  The Trust will use its best efforts to maintain the net asset 
     ---------
value per share of each series at $1.00. In the event that the Trust, or any 
series, incurs a 


                                    - 15 -






<PAGE>
 
loss or liability, which the Trustees, in their sole discretion, determine to be
significant with respect to the maintenance by the Trust of a constant net asset
value of $1.00 per share for each series, the Trustees shall have the power (i) 
to reduce the number of shares of the Trust, or the series, as the case may be,
by that number of full and fractional shares which represent the amount of such 
loss or liability, by reducing the number of shares in the account of each 
Shareholder of the Trust or the series, as the case may be, on a pro rata basis;
(ii) to offset the pro rata share of such loss or liability from the accrued 
dividend account of each Shareholder of the Trust or the series, as the case may
be, and/or (iii) to cause to be recorded on the books of the Trust or the 
series, as the case may be, an asset account in the amount of any such loss or 
liability, which account may be reduced by the amount of dividends declared 
thereafter upon the shares of the Trust or the series, as the case may be, 
outstanding on the day any such loss or liability is incurred, until such asset 
account is reduced to zero.

                          Compensation and Limitation
                           of Liability of Trustees
                          ---------------------------

Compensation
- ------------

     Section 1. The Trustees as such shall be entitled to reasonable 
     ---------
compensation from the Trust; they may fix the amount of their compensation. 
Nothing herein shall in any way prevent the employment of any Trustee for 
advisory, management, legal, accounting, investment banking or other services 
and payment for the same by the Trust.

Limitation of Liability
- -----------------------

     Section 2. The Trustees shall not be responsible or liable in any event for
     ---------
any neglect or wrongdoing of any officer, agent, employee, investment advisor or
manager, principal underwriter or custodian, nor shall any Trustee be
responsible for the act or omission of any other Trustee, but nothing herein
contained shall protect any Trustee against any liability to which he or she
would otherwise be subject by reason of willful misfeasance, bad faith, gross
negligence or reckless disregard of the duties involved in the conduct of his or
her office.
 
     Every note, bond, contract, instrument, certificate, Share or undertaking 
and every other act or thing whatsoever executed or done by or on behalf of the 
Trust or the Trustees or any of them in connection with the Trust shall be 
conclusively deemed to have been executed or done only in or with respect to 
their or his or her capacity as Trustees or Trustee, and such Trustees or 
Trustee shall not be personally liable thereon.

                                 ARTICLE VIII

                                Indemnification
                                ---------------

     Subject to the exceptions and limitations contained in this Article, every 
person who is or has been, a Trustee or officer of the Trust shall be 
indemnified by the Trust to the fullest extent permitted by law against 
liability and against all expenses reasonably incurred or paid by him in 
connection with any claim, action, suit or proceeding in which he becomes 
involved as a party or otherwise by virtue of his being or having been a Trustee
or officer and against amounts paid or incurred by him in settlement thereof.

     No indemnification shall be provided hereunder to a Trustee or officer:

     (a)  against any liability to the Trust or its stockholders by reason of a
          final adjudication by the court or other body before which the
          proceeding was brought that he engaged in willful misfeasance, bad
          faith, gross negligence or reckless disregard of the duties involved
          in the conduct of his office;

     (b)  with respect to any matter as to which he shall have been finally
          adjudicated not to have acted in good faith in the reasonable belief
          that his action was in the best interests of the Trust;

     (c)  in the event of a settlement or other disposition, not involving a
          final adjudication as provided in paragraph (a) or (b), resulting in a
          payment by a Trustee or officer, unless there has been either a
          determination that such director or officer did not engage in willful
          misfeasance, bad faith, gross negligence or reckless disregard of the
          duties involved in the conduct of his office by the court or other
          body approving the settlement or other disposition or a reasonable
          determination, based on a review of readily available facts (as
          opposed to a full trial-type inquiry) that he did not engage in such
          conduct:

          (i)  by a vote of a majority of the Disinterested Trustees acting on
               the matter (provided that a majority of the Disinterested
               Trustees then in office act on the matter); or

         (ii)  by written opinion of independent legal counsel.

                                    - 17 -
<PAGE>

     The rights of indemnification hereinafter provided may be insured against 
by policies maintained by the Trust, shall be severable, shall not affect any 
other rights to which any Trustee or officer may now or hereafter be entitled, 
shall continue as to a person who has ceased to be such Trustee or officer and 
shall inure to the benefit of the heirs, executors and administrators of such a 
person. Nothing contained herein shall affect any rights to indemnification to 
which Trust personnel other than Trustees and officers may be entitled by 
contract or otherwise under law.

     Expenses of preparation and presentation of a defense to any claim, action,
suit or proceeding of the character described in the last paragraph of this 
Article shall be advanced by the Trust prior to final disposition thereof upon 
receipt of an undertaking by or on behalf of the recipient to repay such amount 
if it is ultimately determined that he is not entitled to indemnification under 
this Article, provided that either:
         
     (a)  such undertaking is secured by a surety bond or some other 
     appropriate security or the Trust shall be insured against losses arising 
     out of any such advances; or       

     (b)  a majority of the Disinterested Trustees acting on the matter 
     (provided that a majority of the Disinterested Trustees then in office act 
     on the matter) or independent legal counsel in a written opinion shall 
     determine, based upon a review of the readily available facts (as opposed 
     to a full trial-type inquiry), that there is reason to believe that the 
     recipient ultimately will be found entitled to indemnification.

     As used in this Article, a "Disinterested Trustee" is one (i) who is not an
"interested person" of the Trust (as defined by the Investment Company Act of 
1940) (including anyone who has been exempted from being an "interested person" 
by any rule, regulation or order of the Securities and Exchange Commission), and
(ii) against whom none of such actions, suits or other proceedings or another 
action, suit or other proceeding on the same or similar grounds is then or has 
been pending.

     As used in this Article, the words "claim", "action", "suit" or 
"proceeding" shall apply to all claims, actions, suits or proceedings (civil, 
criminal or other, including appeals), actual or threatened; and the words 
"liability" and "expenses" shall include without limitation, attorneys' fees, 
costs, judgments, amounts paid in settlement, fines, penalties and other 
liabilities.

     "In case of any Shareholder or former Shareholder shall be held to be 
personally liable solely by reason of his or her being or having been a 
Shareholder and not because of his or her acts or omissions or for some other 
reason, the Shareholder or former Shareholder (or his or her heirs, executors, 
administrators or other legal representatives or in the case of a corporation or
other entity, its corporate or other general successor) shall be entitled out 
of the assets of the Trust to be held harmless from and indemnified against all
loss and expense arising from such liability."

Trustees, Shareholders, etc. Not Personally Liable; Notice      
- ----------------------------------------------------------

     Section 1.  All persons extending credit to, contracting with or having any
     ---------
claim against the Trust shall look only to the assets of the Trust for payment 
under such credit, contract or claim; and neither the Shareholders not the 
Trustees, nor any of the Trust's officers, employees or agents, whether past, 
present or future, shall be personally liable therefor. Nothing in this 
Declaration of Trust shall protect any Trustee against any liability to which 
such Trustee would otherwise be subject by reason of willful misfeasance, bad 
faith, gross negligence or reckless disregard of the duties involved in the 
conduct of the office of the Trustees.

     Every note, bond, contract, instrument, certificate or undertaking made or 
issued by the Trustees or by any officers or officer shall give notice that this
Declaration of Trust is on file with the Secretary of The Commonwealth of 
Massachusetts and shall recite that the same was executed or made by or on 
behalf of the Trust or by them as Trustees or Trustee or as officers or officer 
and not individually and that the obligations of such instrument are not binding
upon any of them or the Shareholders individually but are binding only upon the 
assets and property of the Trust, and may contain such further recital as he or 
she or they may deem appropriate, but the omission thereof shall not operate to 
bind any Trustees or Trustee or officers or officer or Shareholders or 
Shareholder individually.

Trustee's Good Faith Action, Expert Advice, No Bond or Surety
- -------------------------------------------------------------

     Section 2.  The exercise by the Trustees of their powers and discretions 
     ---------
hereunder shall be binding upon everyone interested. A Trustee shall be liable 
for his or her own willful misfeasance, bad faith, gross negligence or reckless 
disregard of the duties involved in the conduct of the office

 of Trustee, and for nothing else, and shall not be liable for errors of 
judgment or mistakes of fact or law. The Trustees may take advice of counsel or 
other experts with respect to the meaning and operation of this Declaration of 
Trust, and shall be under no liability for any act or omission in accordance 
with such advice or for failing to follow such advice. The Trustees shall not be
required to give any bond as such, nor any surety if a bond is required.

Liability of Third Persons Dealing with Trustees
- ------------------------------------------------

     Section 3.  No person dealing with the Trustees shall be bound to make any
     ---------
inquiry concerning the validity of any transaction made or to be made by the 
Trustees or to see to the application of any payments made or property 
transferred to the Trust or upon its order.

Duration and Termination of Trust
- ---------------------------------

     Section 4.  Unless terminated as provided herein, the Trust shall continue
     ---------
without limitation of time. The Trust may be terminated at any time by vote of 
Shareholders holding at least a majority of the Shares entitled to vote or by 
the Trustees by written notice to the Shareholders. Any series of Shares may be 
terminated at any time by vote of Shareholders holding at least a majority of 
the Shares of such series entitled to vote or by the Trustees by written notice 
to the Shareholders of such series.

     Upon termination of the Trust or of any one or more series of Shares, after
paying or otherwise providing for all charges, taxes, expenses and liabilities, 
whether due or accrued or anticipated, of the particular series as may be 
determined by the Trustees, the Trust shall in accordance with such procedures 
as the Trustees consider appropriate reduce the remaining assets to 
distributable form in cash or shares or other securities, or any combination 
thereof, and distribute the proceeds to the Shareholders of the series involved,
ratably according to the number of Shares of such series held by the several 
Shareholders of such series on the date of termination.

Filing of Copies, References, Headings
- --------------------------------------

     Section 5.  The original or a copy of this instrument and of each amendment
     ---------
hereto shall be kept at the office of the Trust where it may be inspected by any
Shareholder. A copy of this instrument and of each amendment hereto shall be 
filed by the Trust with the Secretary of The Commonwealth of Massachusetts and 
with the Boston City Clerk, as well as any other governmental office where such 
filing may from time to time be required. Anyone dealing with the Trust may

rely on a certificate by an officer of the Trust as to whether or not any such 
amendments have been made and as to any matters in connection with the Trust 
hereunder; and, with the same effect as if it were the original, may rely on a 
copy certified by an officer of the Trust to be a copy of this instrument or of 
any such amendments. In this instrument and in any such amendment, references to
this instrument, and all expressions like "herein", "hereof", and "hereunder", 
shall be deemed to refer to this instrument as amended from time to time. 
Headings are placed herein for convenience of reference only and shall not be 
taken as a part hereof or control or affect the meaning, construction or effect 
of this instrument. This instrument may be executed in any number of 
counterparts each of which shall be deemed an original.

Applicable Law
- --------------

     Section 6.  This Declaration of Trust is made in The Commonwealth of 
     ---------
Massachusetts, and it is created under and is to be governed by and construed 
and administered according to the laws of said Commonwealth. The Trust shall be 
of the type commonly called a Massachusetts business trust, and without limiting
the provisions hereof, the Trust may exercise all powers which are ordinarily 
exercised by such a trust.

Amendments
- ----------

     Section 7.  This Declaration of Trust may be amended at any time by an 
     ---------
instrument in writing signed by a majority of the then Trustees when authorized 
so to do by vote of Shareholders holding a majority of the Shares entitled to 
vote, except that an amendment which shall affect the holders of one or more 
series of Shares but not the holders of all outstanding series shall be 
authorized by vote of the Shareholders holding a majority of the Shares entitled
to vote of each series affected and no vote of Shareholders of a series not 
affected shall be required. Amendments having the purpose of changing the name 
of the Trust or of supplying any omission, curing any ambiguity or curing, 
correcting or supplimenting any defective or inconsistent provision contained 
herein shall not require authorization by Shareholder vote.


     IN WITNESS WHEREOF, the undersigned have hereunto set their hands and seals
in the City of Boston, Massachusetts for themselves and their assigns, as of the
day and year first above written.

                   WRITTEN INSTRUMENT AMENDING THE AGREEMENT
                           AND DECLARATION OF TRUST



     The undersigned, being at least a majority of the Trustees of TrustFunds 
Liquid Asset Trust, a business trust organized under the laws of the 
Commonwealth of Massachusetts pursuant to an Agreement and Declaration of Trust 
dated July 20, 1981 (the "Declaration of Trust"), and being authorized by the 
Unitholders of said Trust to effect this amendment, do hereby amend pursuant 
to Article IX, Section 7 of the Declaration of Trust, effective upon the signing
of this instrument, the Declaration of Trust as follows:

     Article III, Section 1, Article IV, Section 7, and Article V, Section 1 are
hereby amended in their entirety to read as follows:

                                  ARTICLE III

                                    Shares

Division of Beneficial Interest

     Section 1.  The Shares of the Trust shall be issued in one or more series 
as the Trustees may, without shareholder approval, authorize. Each series shall 
be preferred over all other series in respect of the assets allocated to that 
series. The beneficial interest in each series shall at all times be divided 
into Shares, without par value, each of which shall represent an equal 
proportionate interest in the series with each other Share of the same series, 
none having priority or preference over another. The number of Shares authorized
shall be unlimited, and the Shares so authorized may be represented in part by 
fractional shares. The Trustees may from time to time divide or combine the 
Shares of any series or class into a greater or lesser number without thereby 
changing the proportionate beneficial interests in the series or class.

                                  ARTICLE IV

                                 The Trustees

Advisory, Management and Distribution

     Section 7.  The Trustees may, at any time and from time to time, contract 
for exclusive or nonexclusive advisory and/or


<PAGE>
 

management services with SEI Financial Management Corporation (the "Manager"), a
Delaware corporation, and/or any other corporation, trust, association or other 
organization, every such contract to comply with such requirements and 
restrictions as may be set forth in the By-Laws; and any such contract may 
contain such other terms interpretive of or in addition to said requirements and
restrictions as the Trustees may determine, including, without limitation, 
authority to determine from time to time what investments shall be purchased, 
held, sold, or exchanged and what portion, if any, of the assets of the Trust 
shall be held uninvested and to make changes in the Trust's investments. The 
Trustees may also, at any time and from time to time, contract with any other 
corporation, trust, association or other organization, appointing it exclusive 
or nonexclusive distributor or principal underwriter for the Shares, every such
contract to comply with such requirements and restrictions as may be set forth 
in the By-Laws; and any such contract may contain such other terms interpretive 
of or in addition to said requirements and restrictions as the Trustees may 
determine.

     The fact that:
     
           (i)  any of the Shareholders, Trustees or officers of the Trust is a 
     shareholder, director, officer, partner, trustee, employee, manager,
     advisor, principal underwriter, or distributor or agent of or for any
     corporation, trust, association, or other organization, or of or for any
     parent or affiliate of any organization, with which an advisory or
     management or principal underwriter's or distributor's contract, or
     transfer, Shareholder services or other agency contract may have been or
     may hereafter be made, or that any such organization, or any parent or
     affiliate thereof, is a Shareholder or has an interest in the Trust, or
     that

           (ii) any corporation, trust, association or other organization with
     which an advisory or management or principal underwriter's or distributor's
     contract, or transfer, Shareholder services or other agency contract may
     have been or may hereafter be made also has an advisory or management
     contract, or principal underwriter's or distributor's contract, or
     transfer, Shareholder services or other agency contract with one or more
     other corporations, trusts, associations, or other organizations, or has
     other businesses or interests.
     

shall not affect the validity of any such contract or disqualify any 
Shareholder, trustee or officer of the Trust from voting upon or executing the 
same or create any liability or accountability to the Trust or its Shareholders.

                                   ARTICLE V

                   Shareholders' Voting Powers and Meetings

Voting Powers

     Section 1. The Shareholders shall have power to vote only (i) for the 
election or removal of Trustees as provided in Article IV, Section 1, (ii) with 
respect to the approval of any investment advisory contract as provided in 
Article IV, Section 7, (iii) with respect to any termination of the Trust to the
extent and as provided in Article IX, Section 4, (iv) with respect to any 
amendment of this Declaration of Trust to the extent and as provided in Article 
IX, Section 7, (v) to the same extent as the stockholders of a Massachusetts 
business corporation as to whether or not a court action, proceeding or claim 
should or should not be brought or maintained derivatively or as a class action 
on behalf of the Trust or the Shareholders, and (vi) with respect to such 
additional matters relating to the Trust as may be required by law, this 
Declaration of Trust, the By-Laws or any registration of the Trust with the 
Commission (or any successor agency) or any state, or as the Trustees may 
consider necessary or desirable.

     Each whole Share shall be entitled to one vote as to any matter on which it
is entitled to vote and each fractional Share shall be entitled to a
proportionate fractional vote. On any matter submitted to a vote of Shareholders
all Shares of the Trust then entitled to vote, irrespective of series, shall be
voted in the aggregate and not by series, except (i) when required by the 1940
Act, Shares shall be voted by individual series, in which event, unless
otherwise required by the 1940 Act, a vote of Shareholders of all shares of the
Trust, irrespective of series, shall not be required; and (2) when the Trustees
have determined that the matter affects only the interests of one or more
series, than only Shareholders of such series shall be entitled to vote thereon.
There shall be no cumulative voting in the election of Trustees. Shares may be
voted in person or by proxy.

     A proxy with respect to Shares held in the name of two or more persons 
shall be valid if executed by any one of them unless at or prior to the exercise
of the proxy the Trust receives a specific written notice to the contrary from 
any of them. A proxy purporting to be executed by or on behalf of a Shareholder 
shall be deemed valid unless challenged at or prior to its exercise and the 
burden of proving invalidity shall rest on the challenger.

     Until Shares are issued, the Trustees may exercise all rights of 
Shareholders and may take any action required by law, this Declaration of Trust 
or the By-Laws to be taken by Shareholders.

hands hereunder as of this 10th day of December, 1986.

                            INVESTMENT ADVISORY AGREEMENT
                            -----------------------------

AGREEMENT made this 30th day of October, 1985 by and between TrustFunds Liquid 
Asset Trust, a Massachusetts business trust (the "Trust"), a Wellington 
Management Company/Thorndike, Doran, Paine & Lewis, a Massachusetts partnership 
(the "Adviser").

WHEREAS, the Trust is an open-end, diversified management investment company 
registered under the Investment Company Act of 1940, as amended, consisting of 
several series of shares, each having its own investment policies; and

WHEREAS, the Trust has retained SEI Financial Management Corporation (the 
"Manager") to provide administration of the Trust's operations, subject to the 
control of the Board of Trustees;

WHEREAS, the Trust desires to retain the Adviser to render investment management
services to the Trust with respect to its Treasury Portfolio, Agency Portfolio, 
Commercial Portfolio and Prime Obligation Portfolio and such other portfolios as
the Trust and the Adviser may agree on (the "Portfolios") and the Adviser is 
will to render such services;

NOW, THEREFORE, in consideration of mutual covenants herein contained, the 
parties hereto agree as follows:

     1. Duties of Adviser. The Trust employs the Adviser to manage the
     investment and reinvestment of the assets, and to continuously review,
     supervise, and administer the investment program of the Portfolios, to
     determine in its discretion the securities to be purchased or sold, to
     provide the Manager and the Trust with records concerning the Adviser's
     activities which the Trust is required to maintain, and to render regular
     reports to the Manager and to the Trust's officers and Trustees concerning
     the Adviser's discharge of the foregoing responsibilities. The Adviser
     shall discharge the foregoing responsibilities subject to the control of
     the officers and the Trustees of the Trust and in compliance with such
     policies as the Trustees may from time to time establish, and in compliance
     with the objectives, policies, and limitations for each such Portfolio set
     forth in the Trust's prospectus from time to time, and applicable laws and
     regulations. The Adviser accepts such employment and agrees, at its own
     expense, to render the services and to provide the office space,
     furnishings and equipment and the personnel required by it to perform the
     services on the terms and for the compensation provided herein.
<PAGE>
 
     2. Portfolio Transactions. The Adviser is authorized to select the brokers
     or dealers that will execute the purchases and sales of portfolio
     securities for the Portfolios and is directed to use its best efforts to
     obtain the best net results as described in the Trust's prospectus from
     time to time. The Adviser will promptly communicate to the Manager and to
     the officers and the Trustees of the Trust such information relating to
     portfolio transactions as they may reasonably request.

     3. Compensation of the Advisor. For the services to be rendered by the
     Adviser as provided in Sections 1 and 2 of this Agreement, the Trust shall
     pay to the Adviser at the end of each month, a fee calculated by applying a
     daily rate, based on the following annual percentage rates, to the Assets
     (hereinafter defined):

            .075% on the first $500 million of Assets;
            .02% on the Assets in excess of $500 million.

     The terms "Assets" shall mean the daily net assets of the Portfolios
     managed by the Adviser. The fee, as determined above, shall be based on
     average Assets for the month involved (less any assets of such Portfolios
     held in non-interest bearing special deposits with a Federal Reserve Bank).

     4. Other Services. At the request of the Trust or the Manager, the Adviser
     in its discretion may make available to the Trust, office facilities,
     equipment, personnel, and other services. Such office facilities,
     equipment, personnel, and services shall be provided for or rendered by the
     Adviser and billed to the Trust or the Manager at the Adviser's costs.

     5. Reports. The Trust and the Adviser agree to furnish to each other, if
     applicable, current prospectuses, proxy statements, reports to
     shareholders, certified copies of their financial statements, and such
     other information with regard to their affairs as each may reasonably
     request.

     6. Status of Adviser. The services of the Adviser to the Trust are not to
     be deemed exclusive, and the Adviser shall be free to render similar
     services to others so long as its services to the Trust are not impaired
     thereby. The Adviser shall be deemed to be an independent contractor and
     shall, unless otherwise expressly provided or authorized, have no authority
     to act for or represent the Trust in any way or otherwise be deemed an
     agent of the Trust.

     7. Certain Records. Any records required to be maintained and preserved
     pursuant to the provisions of Rule 31a-1 and Rule 31a-2 promulgated under
     the Investment Company Act which are prepared


<PAGE>
 
     or maintained by the Adviser on behalf of the Trust are the property of the
     Trust and will be surrendered promptly to the Trust on request.

     8. Liability of Adviser. No provision of this Agreement shall be deemed to
     protect the Adviser against any liability to the Trust or its shareholders
     to which it might otherwise be subject by reason of any willful
     misfeasance, bad faith, or gross negligence in the performance of its
     duties or the reckless disregard of its obligations under this Agreement.

     9. Permissible Interests. Trustees, agents, and shareholders of the Trust
     are or may be interested in the Adviser (or any successor thereof) as
     directors, partners, officers, or shareholders or otherwise; directors,
     partners, officers, agents, and shareholders of the Adviser are or may be
     interested in the Trust as Trustees, shareholders or otherwise; and the
     Adviser (or any successor) is or may be interested in the Trust as a
     shareholder or otherwise.

     10. Duration and Termination. This Agreement, unless sooner terminated as
     provided herein, shall continue as to each Portfolio until October 30,
     1987, and thereafter, for periods of one year so long as such continuance
     thereafter is specifically approved at least annually (a) by the vote of a
     majority of those Trustees of the Trust who are not parties to this
     Agreement or interested persons of any such party, cast in person at a
     meeting called for the purpose of voting on such approval, and (b) by the
     Trustees of the Trust or by vote of a majority of the outstanding voting
     securities of each Portfolio; provided, however, that if the shareholders
     of any Portfolio fail to approve the Agreement as provided herein, the
     Adviser may continue to serve hereunder in the manner and to the extent
     permitted by the Investment Company Act of 1940 and rules thereunder. The
     foregoing requirement that continuance of this Agreement be "specifically
     approved at least annually" shall be construed in a manner consistent with
     the Investment Company Act of 1940 and the rules and regulations
     thereunder. This Agreement may be terminated as to any Portfolio at any
     time, without the payment of any penalty by vote of a majority of the
     Trustees of the Trust or by vote of a majority of the outstanding voting
     securities of the Portfolio on not less than 30 days nor more than 60 days
     written notice to the adviser, or by the Adviser at any time without the
     payment of any penalty, on 90 days written notice to the Trust. This
     Agreement will automatically and immediately terminate in the event of its
     assignment. Any notice under this Agreement shall be given in writing,
     addressed and delivered, or mailed postpaid, to the other party at any
     office of such party.

<PAGE>
 
      As used in this Section 10, the terms "assignment", "interested persons",
      and a "vote of a majority of the outstanding voting securities" shall have
      the respective meanings set forth in the Investment Company Act of 1940
      and the rules and regulations thereunder; subject to such exemptions as
      may be granted by the Securities and Exchange Commission under said Act.

      11. Severability. If any provision of this Agreement shall be held or made
      invalid by a court decision, statute, rule or otherwise, the remainder of
      this Agreement shall not be affected thereby.

A copy of the Declaration of Trust of the Trust is on file with the Secretary of
The Commonwealth of Massachusetts, and notice is hereby given that this 
instrument is executed on behalf of the Trustees of the Trust as Trustees, and 
are not binding upon any of the Trustees, officers, or shareholders of the Trust
individually but binding only upon the assets and property of the Trust.

IN WITNESS WHEREOF, the Parties hereto have caused this Agreement to be executed
as of the day and year first written above.

                             MANAGEMENT AGREEMENT

      THIS AGREEMENT is made as of this 31st day of October, 1986 by and between
TrustFunds Liquid Asset Trust (the "Trust"), a Massachusetts business trust, and
SEI Financial Management Corporation (the "Manager"), a Delaware corporation.

      WHEREAS the Trust is a diversified open-end investment company registered 
under the Investment Company Act of 1940, as amended (the "1940 Act"); and

      WHEREAS the Manager is willing to provide, or oversee the performance of 
others who will provide management, administrative, transfer agent and 
unitholder servicing services to the Trust's Treasury Portfolio, Agency 
Portfolio, Commercial Portfolio, Prime Obligation Portfolio, Institutional Cash 
Portfolio, and such other portfolios as the Trust and the Manager may agree on 
(collectively, "Portfolios"), on the terms and conditions hereinafter set forth;

      NOW, THEREFORE, in consideration of the premises and the covenants 
hereinafter contained, the Trust and the Manager hereby agree as follows:

      ARTICLE 1.  Retention of the Manager.  The Trust hereby retains the 
                  ------------------------
Manager to act as the Manager and Unitholder Servicing Agent of the Portfolios 
and to furnish the Portfolios with the management, administrative, transfer 
agent and unitholder servicing services as set forth below. The Manager hereby 
accepts such employment to perform the duties set forth below. The Manager 
shall, for all purposes herein, be deemed to be an independent contractor and, 
unless otherwise expressly provided or authorized, shall have no authority to 
act for or represent the Trust in any way and shall not be deemed an agent of 
the Trust. All of the Manager's duties shall be subject always to the 
objectives, policies and restrictions contained in the Trust's current 
registration statement under the 1940 Act, to the Trust's Declaration of Trust 
and By-Laws, to the provisions of the 1940 Act, and to any other guidelines that
may be established by the Trust's Trustees. The Manager shall calculate the 
daily net asset value of the Portfolios in accordance with the procedures 
prescribed in the Trust's Registration Statement and such other procedures as 
may be established by the Trustees of the Trust.

      ARTICLE 2.  Evaluation Services.  The Manager shall oversee and monitor 
                  -------------------
the performance of the Portfolios' investment adviser and shall furnish to the 
Trust such information, evaluations, analyses and opinions regarding said 
performance as the Trustees may, from time to time, reasonably request; 
provided, however, that the Manager shall have no authority to make and shall 
not make investment decisions for the Portfolios nor furnish any advice with 
respect to the desireability of making such investment decisions.
<PAGE>
 
      ARTICLE 3.  Transfer Agent Services.  The Manager will act as Transfer 
                  -----------------------
Agent for the Portfolios and, as such, will record in an account (the "Account")
the total number of units of beneficial interest ("Units") of each Portfolio 
issued and outstanding from time to time and will maintain Unit transfer records
in which it will note the names and registered addresses of Unitholders, and the
number of Units from time to time owned by each of them. Each Unitholder will be
assigned one or more account numbers. The Manager is authorized to set up 
accounts and record transactions in the accounts on the basis of instructions 
received from Unitholders when accompanied by remittance in appropriate amount 
as provided in the Trust's then current prospectus. The Trust will not issue 
certificates representing its Units. Whenever Units are purchased or issued, the
Manager shall credit the Account with the Units issued, and credit the proper 
number of Units to the appropriate Unitholder. Likewise, whenever the Manager 
has occasion to redeem Units owned by a Unitholder, the Trust authorizes the 
Manager to process the transaction by making appropriate entries in its Unit 
transfer records and debiting the Account.

      Upon receipt by the Trust's Wire Agent (currently the United States 
National Bank of Oregon) on behalf of the Manager of funds through the Federal 
Reserve wire system or conversion into Federal funds of funds transmitted by 
other means, for the purchase of Units in accordance with the Trust's current 
prospectus, the Manager shall notify the Trust of such deposits on a daily 
basis. The Manager shall credit the Unitholder's account with the number of 
units purchased according to the price of the Units in effect for such purchases
determined in the manner set forth in the Trust's then current prospectus. The 
Manager shall process each order for the redemption of Units from or on behalf 
of a Unitholder, and shall cause cash proceeds to be wired in Federal funds. The
requirements as to instruments of transfer and other documentation, the 
applicable redemption price and the time of payment shall be as provided in the 
then current prospectus, subject to such supplemental requirements consistent 
with such prospectus as may be established by mutual agreement between the Trust
and Manager. If the Manager or the Trust determines that a request for 
redemption does not comply with the requirements for redemption, the Manager 
shall promptly so notify the Unitholder, together with the reason therefor, and 
shall effect such redemption at the price next determined after receipt of 
documents complying with said standards. On each day that the Trust's custodian 
banks and the New York Stock Exchange are open for business ("Business Day"), 
the Manager shall notify the Custodian of the amount of cash or other assets 
required to meet payments made pursuant to the provisions of this paragraph, and
the Trust shall instruct the Custodian to make available from time to time 
sufficient funds or other assets therefor. The authority of the Manager to 
perform its responsibilities under this paragraph shall be suspended upon 
receipt by it of notification from the Securities and Exchange Commission or the
Trustees of the suspension of the determination of the Trust's net asset value.


                                     - 2 -

     In registering transfers, the Manager may rely upon the opinion of counsel 
in not requiring complete documentation, in registering transfers without 
inquiry into adverse claims, in delaying registration for purposes of such 
inquiry, or in refusing registration where in its judgment an adverse claim 
requires such refusal.

     The Trust warrants that it has or shall deliver to the Manager, as transfer
agent:
    
     (a)  a copy of the Declaration of Trust of the Trust, incorporating all 
amendments thereto, certified by the Secretary or Assistant Secretary of the 
Trust;

and continuing existence of the Trust, (ii) the legality of its outstanding 
Units of beneficial interest, and (iii) the number of units authorized for 
issuance and that upon issuance they will be validly issued; and 

     (c)  the Trust's Secretary's or Assistant Secretary's certificate as to the
authorized outstanding Units of the Trust, its address to which notices may be 
sent, the names and specimen signatures of its officers who are authorized to 
sign instructions or requests to the Manager on behalf of the Trust, and the 
name and address of legal counsel to the Trust. In the event of any future 
amendment or change in respect of any of the foregoing, prompt written 
notification of such change shall be given by the Trust to the Manager, together
with copies of all relevant resolutions, instruments or other documents, 
specimen signatures, certificates, opinions or the like as the Manger may deem 
necessary or appropriate.

     ARTICLE 4.  Dividend Disbursing Agent. The Manager shall act as Dividend 
                 -------------------------
Disbursing Agent for the Trust and, as such, in accordance with the provisions 
of the Trust's Declaration of Trust and then current prospectus, shall prepare 
and wire or credit income and capital gains distributions to Unitholders. The 
Trust agrees that it shall promptly inform the Manager of the declaration of any
dividend or distribution of its Units, and that on or before the payment date of
a distribution, it shall instruct the Custodian to make available, at the 
instruction of the Dividend Disbursing Agent, sufficient funds for the cash 
amount to be paid out. If a Unitholder is entitled to receive additional Units 
by virtue of any such distribution or dividend, appropriate credits will be made
to the Unitholder's account.

     ARTICLE 5.  Other Administrative Services. in addition to the services 
                 -----------------------------
described above, the Manager shall perform or supervise the performance by 
others of other administrative services in connection with the operations of the

selection of and conduct relations with custodians, depositories, accountants, 
underwriters, brokers and dealers, corporate

fiduciaries, insurers, banks and persons in any other capacity deemed to be 
necessary or desirable for the Portfolios' operation. The Manager shall provide 
the Trust with regulatory reporting and related bookkeeping services, all 
necessary office space, equipment, personnel compensation and facilities 
(including facilities for Unitholders' and Trustees' meetings) for handling the 
affairs of the Portfolios and such other services as the Manager shall, from 
time to time, determine to be necessary to perform its obligations under this 
Agreement. The Manager shall make reports to the Trust's Trustees concerning the
performance of its obligations hereunder; furnish advice and recommendations 
with respect to other aspects of the business and affairs of the Portfolios as 
the Trust shall determine desirable; and shall provide the Portfolios' 
Unitholders with the reports described in the Trust's current prospectus. Also, 
the Manager will perform other services for the Trust as agreed to from time to 
time, including, but not limited to, preparation and mailing of appropriate 
federal income tax forms; mailing the annual reports of the Trust; preparing 
an annual list of Unitholders; furnishing the Trust with such reports regarding 
the sale and redemption of Units as may be required in order to comply with 
federal and state securities law; and mailing notices of Unitholders' meetings, 
proxies and proxy statements, for all of which the Trust will pay the Manager's 
out-of-pocket expenses.

      ARTICLE 6.  Allocation of Charges and Expenses.
                  ----------------------------------

      (A)  The Manager.  The Manager shall furnish at its own expense the 
           -----------
executive, supervisory and clerical personnel necessary to perform its 
obligations under this Agreement. The Manager shall also provide the items which
it is obligated to provide under this Agreement, and shall pay all compensation,
if any, of officers of the Trust as well as all Trustees of the Trust who are 
affiliated persons of the Manager or of any affiliated corporation; provided, 
however, that unless otherwise specifically provided, the Manager shall not be 
obligated to pay the compensation of any employee of the Manager retained by the
Trustees of the Trust to perform services on behalf of the Trust.

      (B)  The Trust.  The Trust assumes and shall pay or cause to be paid all 
           ---------
other expenses of the Trust not otherwise allocated herein, including, without 
limitation, organizational costs, taxes, expenses for legal and auditing 
services, the expenses of preparing (including typesetting), printing and

     ARTICLE 7.  Compensation of the Manager
                 ---------------------------

     (A)  Management Fee.  For the services to be rendered, the facilities 
          --------------
furnished and the expenses assumed by the Manager pursuant to this Agreement, 
the Trust shall pay to the Manager compensation at an annual rate specified in 
the Schedules which are attached hereto and made a part of this Agreement 
("Schedules").  Such compensation shall be calculated and accrued daily, and 
paid to the Manager monthly (subject to any expenses to be borne by the Manager 
under Article 7(B) herein).  If this Agreement becomes effective subsequent to 
the first day of a month or terminates before the last day of a month, the 
Manager's compensation for that part of the month in which this Agreement is in 
effect shall be prorated in a manner consistent with the calculation of the 
fees as set forth above.  Payment of the Manager's compensation for the 
preceding month shall be made promptly after completion of the 
computations by paragraph (B) of this Article 7.

     (B)  Excess Expenses.  If the expenses of any Portfolio for any fiscal year
          ---------------
(including fees and other amounts payable to the Manager, but excluding 
interest, taxes, brokerage costs, litigation and other extraordinary costs) as 
calculated every Business Day would exceed (i) the annual rate for any Portfolio
as specified in the attached Schedules or (ii) the expense limitations imposed 
on investment companies by any applicable stature or regulatory authority of any
jurisdiction in which Units are qualified for offer and sale, the Manager shall 
bear such excess cost of such portfolio.  However, the Manager will not bear 
expenses of the Trust or any Portfolio thereof to an extent which would result 
in the Trust's inability to qualify as a regulated investment company under 
provisions of the Internal Revenue Code.  Payment of expenses by the Manager 
pursuant to this Article 7(B) shall be settled on a monthly basis (subject to 
fiscal year end reconciliation) by a reduction in the fee payable to Manager for
such month pursuant to Article 7(A) above and, if such reduction shall be 
insufficient to offset such expenses, by reimbursing the Trust.  Any excess 
expenses borne under Article 7(B)(i) (including any fees waived by the Manager) 
or such excess expenses of the Trust borne by the Manager since May 25, 1984
pursuant to earlier agreements between the Manager and the Trust may be 
recovered by the Manager from the Trust when such recovery would not cause the
applicable Portfolio's expenses to exceed the expense limitation set forth in 
the attached Schedules.

     (C)  Compensation From Transactions.  The Trust hereby authorizes any 
          ------------------------------
entity or person associated with the Manager which is a member of a national 
securities exchange to effect any transaction on the exchange for the account of
the Trust which is permitted by Section 11(a) of the Securities Exchange Act of 
1934 and Rule 11a2-2(T) thereunder, and the Trust hereby consents to the 
retention of compensation for such transactions in accordance with Rule 
11a2-2(T)(a)(2)(iv).

                                      -5-

<PAGE>
 
     (D)  Survival of Compensation Rates. All rights of compensation under this 
          ------------------------------
Agreement shall survive the termination of this Agreement.

     ARTICLE 8.  Limitation of Liability of the Manager. The duties of the 
                 --------------------------------------
Manager shall be confined to those expressly set forth herein, and no implied
duties are assumed by or may be asserted against the Manager hereunder. The
Manager shall not be liable for any error of judgment or mistake of law or for
any loss arising out of any investment or for any act or omission in carrying 
out its duties hereunder, except a loss resulting from willful misfeasance, bad
faith or gross negligence in the performance of its duties, or by reason of
reckless disregard of its obligations and duties hereunder, except as may
otherwise be provided under provisions of applicable state law which cannot be
waived or modified hereby. (As used in this Article 8, the term "Manager" shall
include directors, officers and employees and other corporate agents of the
Manager as well as that corporation itself.) So long as the Manager acts in good
faith and with due diligence and without gross negligence, the Trust assumes
full responsibility and shall indemnify the Manager and hold it harmless from
and against any and all actions, suits and claims, whether groundless or
otherwise, and from and against any and all losses, damages, costs, charges,
reasonable counsel fees, and disbursements, payments, expenses and liabilities
(including reasonable investigation expenses) arising directly or indirectly out
of said management and transfer, dividend disbursing and unitholder servicing
agency relationship to the Trust or any other service rendered to the Trust
hereunder. The indemnity and defense provisions set forth herein shall
indefinitely survive the termination of this Agreement. The rights hereunder
shall include the right to reasonable advances of defense expenses in the event
of any pending or threatened litigation with respect to which indemnification
hereunder may ultimately be merited. In order that the indemnification provision
contained herein shall apply, however, it is understood that if in any case the
Trust may be asked to indemnify or hold the Manager harmless, the Trust shall be
fully and promptly advised of all pertinent facts concerning the situation in
question, and it is further understood that the Manager will use all reasonable
care to identify and notify the Trust promptly concerning any situation which
presents or appears likely to present the probability of such a claim for
indemnification against the Trust, but failure to do so in good faith shall not
affect the rights thereunder.

     The Manager may apply to the Trust at any time for instructions and may 
consult counsel for the Trust or its own counsel and with accountants and other 
experts with respect to any matter arising in connection with the Manager's 
duties, and the Manager shall not be liable or accountable for any action taken 
or omitted by it in good faith in accordance with such instruction or with the 
opinion of such counsel, accountants or other experts. Also, the Manager shall
be protected in acting upon any document which it reasonably believes to be
genuine and to have been signed by the proper person or persons.

                                     - 6 -
<PAGE>
 
Nor shall the Manager be held to have notice of any change of authority of any 
officer, employee or agent of the Trust until receipt of written notice thereof 
from the Trust.

      ARTICLE 9.  Activities of the Manager.  The services of the Manager 
                  -------------------------
rendered to the Trust are not to be deemed to be exclusive. The Manager is free 
to render such services to others and to have other businesses and interests. It
is understood that Trustees, officers, employees and Unitholders of the Trust 
are or may be or become interested in the Manager, as directors, officers, 
employees and shareholders or otherwise and that directors, officers, employees 
and shareholders of the Manager and its counsel are or may be or become 
similarly interested in the Trust, and that the Manager may be or become 
interested in the Trust as a Unitholder or otherwise.

      ARTICLE 10.  Duration and Termination of this Agreement.  This Agreement, 
                   ------------------------------------------
unless terminated sooner as provided herein, 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 this Agreement or 
interested persons of any such party, cast in person at a Board of Trustees 
meeting called for the purpose of voting on such approval. This 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 hereto. Any notice under this Agreement shall be given in writing, 
addressed and delivered, or mailed postpaid, to the other party at the 
designated mailing address of such party.

      This Agreement shall not be assignable by either party without the written
consent of the other party.

      ARTICLE 11.  Amendments.  This Agreement may be amended by the parties 
                   ----------
hereto only if such amendment is specifically approved (i) by the vote of a 
majority of the Trustees of the Trust, who are not parties to this Agreement or 
interested persons of any such party, cast in person at a Board of Trustees 
meeting called for the purpose of voting on such approval. For special cases, 
the parties hereto may amend such procedures set forth herein as may be 
appropriate or practical under the circumstances, and the Manager may 
conclusively assume that any special procedure which has been approved by the 
Trust does not conflict with or violate any requirements of its Declaration of

                            DISTRIBUTION AGREEMENT

     THIS AGREEMENT is made this 29th day of November, 1982, between TrustFunds 
Liquid Asset Trust, a Massachusetts business trust ("Trust"), and SEI Financial 
Services Company, a Pennsylvania corporation ("Distributor").

     NOW THEREFORE, in consideration of the mutual covenants hereinafter 
contained, the Trust and Distributor hereby agree as follows:

     1.  Sale of Units.  The Trust grants to the Distributor the right to sell 
         -------------
units of the Trust, as agent and on behalf of the Trust, during the term of 
this Agreement and subject to the registration requirements of the Securities 
Act of 1933, as amended (the "Act"), and of the laws governing the sale of 
securities in the various states ("Blue Sky laws").

     2.  Sale of Units by the Trust.  The rights granted to the Distributor 
         --------------------------
shall be nonexclusive, and the Trust reserves the right to sell its units 
directly to investors on applications received and processed by the Trust's 
Transfer Agent.

     3.  Solicitation of Sales.  In consideration of these rights granted to the
         ---------------------
Distributor, the Distributor agrees to use all reasonable efforts, consistent 
with its other business, to obtain purchasers for shares of the Trust, provided,
however, that the Distributor shall not be

<PAGE>
 
prevented from entering into like arrangements with other issuers. The 
provisions of this paragraph do not obligate the Distributor to register as a 
broker or dealer under the Blue Sky laws of any jurisdiction which it determines
would be unreasonable to do so or to maintain its registration in any 
jurisdiction in which it is now registered. 

     4.  Authorized Representations. The Distributor is not authorized by the 
         --------------------------
Trust to give any information or to make any representations other than those 
contained in the appropriate registration statements or prospectuses filed with 
the Securities and Exchange Commission under the Act (as these registration 
statements and prospectuses may be amended from time to time), or contained in 
unitholder reports or other material that may be prepared by or on behalf of 
the Trust for the Distributor's use. The Distributor may prepare and distribute 
sales literature and other material as it may deem appropriate, provided it has 
been cleared with the Trust.

     5.  Portfolio Securities. Portfolio securities of the Trust may not be 
         --------------------
bought or sold by or through the Distributor.

     6.  Registration of Shares. The Trust agrees that it will take all action 
         ----------------------
necessary to register shares under the Act so that there will be available for 
sale the number of units the Distributor may reasonably be expected to sell. 
The Trust shall make available to the Distributor such 

                                     - 2 -

<PAGE>
 
number of copies of its currently effective prospectus as the Distributor may 
reasonably request.  The Trust shall furnish to the Distributor copies of all
information, financial statements and other papers which the Distributor may
reasonably request for use in connection with the distribution of units of the 
Trust.

     7.  Expenses.  The Trust shall pay all fees and expenses (a) in connection 
         --------
with the  preparation, setting in type and filing of any registration statement 
and prospectus under the 1933 Act and amendments for the issue of its units, (b)
of preparing, setting in type, printing and mailing any report or other 
communication to unitholders of the Trust in their capacity as such, and (c) of 
preparing, setting in type, printing and mailing prospectuses sent annually to 
existing unitholders.  To the extent provided in the Trust's annual budget under
its Distribution Plan, the Trust shall reimburse the Distributor for (i) the 
cost of prospectuses, reports to unitholders, sales literature and other 
materials for potential investors, (ii) costs of complying with state and 
foreign securities laws pertaining to the distribution of units, (iii) 
advertising, and (iv) expenses incurred in selling units.  To the extent not so 
provided, the Distributor shall pay expenses of (x) any supplemental sales 
literature used by the Distributor in connection with such offering, and (y) 
advertising in connection with such offering.


                                      -3-

     8.  Indemnification.  The Trust agrees to indemnify and hold harmless the 
         ---------------
Distributor and each of its directors and officers and each person, if any, who 
controls the Distributor within the meaning of Section 15 of the Act against any
loss, liability, claim, damages or expense (including the reasonable cost of 
investigating or defending any alleged loss, liability, claim, damages, or 
expense and reasonable counsel fees incurred in connection therewith), arising 
by reason of any person acquiring any shares, based upon the ground that the 
registration statement, prospectus, unitholder reports or other information 
filed or made public by the Trust (as from time to time amended), included an 
untrue statement of a material fact or omitted to state a material fact required
to be stated or necessary in order to make the statements not misleading.  
However, the Trust does not agree to indemnify the Distributor or hold it 
harmless to the extent that the statement or omission was made in reliance upon,
and in conformity with, information furnished to the Trust by or on behalf of 
the Distributor.  In no case (i) is the indemnity of the Trust in favor of the
Distributor or any person indemnified to be deemed to protect the Distributor or
any person against any liability to the Trust or its unitholders to which the 
Distributor or such person would otherwise by subject by reason of wilful 
misfeasance, bad faith or gross negligence in the performance of its duties or 
by reason of its reckless


                                      -4-
<PAGE>
 
disregard of its obligations and duties under this Agreement, or (ii) is the 
Trust to be liable under its indemnity agreement contained in this paragraph 
with respect to any claim made against the Distributor or any person indemnified
unless the Distributor or any person shall have notified the Trust in writing of
the claim within a reasonable time after the summons or other first written 
notification giving information of the nature of the claim shall have been 
served upon the Distributor or any person (or after the Distributor or the 
person shall have received notice of service on any designated agent). However, 
failure to notify the Trust of any claim shall not relieve the Trust from any 
liability which it may have to the Distributor or any person against whom such 
action is brought otherwise than on account of its indemnity agreement contained
in this paragraph. The Trust shall be entitled to participate at its own expense
in the defense, or if it so elects, to assume the defense of any suit brought to
enforce any claims, but if the Trust elects to assume the defense, the defense 
shall be conducted by counsel chosen by it and satisfactory to the Distributor 
or person or persons, defendant or defendants in the suit. In the event the 
Trust elects to assume the defense of any suit and retain counsel, the 
Distributor, officers or directors or controlling person or persons, defendant 
or defendants in the suit, shall bear the fees and expenses of any additional 
counsel retained by 

                                     - 5 -
<PAGE>
 
them.  If the Trust does not elect to assume the defense of any suit, it will 
reimburse the Distributor, officers or directors or controlling person or 
persons, defendant or defendants in the suit, for the reasonable fees and 
expenses of any counsel retained by them.  The Trust agrees to notify the 
Distributor promptly of the commencement of any litigation or proceedings 
against it or any of its officers or Trustees in connection with the issuance or
sale of any of the shares.

     The Distributor also covenants and agrees that it will indemnify and hold
harmless the Trust and each of its Trustees and officers and each person, if 
any, who controls the Trust within the meaning of Section 15 of the Act, against
any loss, liability, damages, claim or expense (including the reasonable cost of
investigating or defending any alleged loss, liability, damages, claim or 
expense and reasonable counsel fees incurred in connection therewith) arising by
reason of any person acquiring any shares, based upon the Act or any other
statute or common law, alleging any wrongful act of the Distributor or any of
its employees or alleging that the registration statement, prospectus,
unitholder reports or other information filed or made public by the Trust (as
from time to time amended), included an untrue statement of a material fact or
omitted to state a material fact required to be stated or necessary in order to
make the statements not misleading, insofar as the statement


                                      -6-
<PAGE>

     
or omission was made in reliance upon, and in conformity with information 
furnished to the Trust by or on behalf of the Distributor. In no case (i) is the
indemnity of the Distributor in favor of the Trust or any person indemnified to 
be deemed to protect the Trust or any person against any liability to which the 
Trust or such person would otherwise be subject by reason of wilful misfeasance,
bad faith or gross negligence in the performance of its duties or by reason of 
its reckless disregard of its obligations and duties under this Agreement, or 
(ii) is the Distributor to be liable under its indemnity agreement contained in 
this paragraph with respect to any claim made against the Trust or any person 
indemnified unless the Trust or person, as the case may be, shall have notified 
the Distributor in writing of the claim within a reasonable time after the 
summons or other first written notification giving information of the nature of 
the claim shall have been served upon the Trust or any person (or after the 
Trust or such person shall have received notice of service on any designated 
agent). However, failure to notify the Distributor of any claim shall not 
relieve the Distributor from any liability which it may have to the Trust or 
any person against whom the action is brought otherwise than on account of its 
indemnity agreement contained in this paragraph. In the case of any notice to 
the Distributor, it shall be entitled to participate, at its own expense, in the
defense or, if it so      

                                     - 7 -
<PAGE>
 
elects, to assume the defense of any suit brought to enforce the claim, but if 
the Distributor elects to assume the defense, the defense shall be conducted by 
counsel chosen by it and satisfactory to the Trust, to its officers and Trustees
and to any controlling person or persons, defendant or defendants in the suit.  
In the event that the Distributor elects to assume the defense of any suit and
retain counsel, the Trust or controlling persons, defendant or defendants in the
suit, shall bear the fees and expenses of any additional counsel retained by 
them.  If the Distributor does not elect to assume the defense of any suit, it 
will reimburse the Trust, officers and Trustees or controlling person or 
persons, defendant or defendants in the suit, for the reasonable fees and 
expenses of any counsel retained by them.  The Distributor agrees to notify the 
Trust promptly of the commencement of any litigation or proceedings against it 
in connection with issue and sale of any of the units.

      9.  Effective Date.  This Agreement shall be effective upon its execution 
          --------------
or upon such later date as shall be agreed upon by the President of the Trust 
and the President of the Distributor, and unless terminated as  provided, shall 
continue in force for two (2) years from the date of its execution and 
thereafter from year to year, provided continuance after the two (2) year period
is approved by (i) either the vote of a majority of the Trustees of the Trust


                                      -8-
<PAGE>
 
or the vote of a majority of the outstanding voting securities of the Trust, and
(ii) the vote of a majority of those Trustees of the Trust who are not parties 
to this Agreement or interested persons of any party, case in person at a 
meeting called for the purpose of voting on the approval. This Agreement shall 
automatically terminate, in the event of its assignment. As used in this 
paragraph the terms "vote of a majority of the outstanding voting 
securities," "assignment," and "interested person," shall have the respective 
meanings specified in the Investment Company Act of 1940 as now in effect or as 
hereafter amended. In addition to termination by failure to approve continuance 
or by assignment, this Agreement may at any time be terminated by either party 
upon not less than sixty days' prior written notice to the other party.

     10. Notices. Any notice required or permitted to be given by either party
         -------
to the other shall be deemed sufficient if sent by registered or certified 
mail, postage prepaid, addressed by the party giving notice to the other party
at the last address furnished by the other party to the party giving notice: if
to the Trust, at 28 State Street, Boston, Massachusetts, and if to the
Distributor, at 680 E. Swedesford Road, Wayne, Pennsylvania 19087.

     11. Limitation of Liability. A copy of the Declaration of Trust of the 
         -----------------------

given that this Agreement is executed on behalf of the Trustees of the Trust as 
Trustees, and not individually and that the obligations of this instrument are 
not binding upon any of the Trustees, officers or unitholders of the Trust 
individually but binding only upon the assets and property of the Trust.

     IN WITNESS, the Trust and Distributor have each duly executed this 
Agreement, as of the day and year above written.

                              CUSTODIAN AGREEMENT


This Agreement, dated 1st day of September 1981 made by and between TrustFunds 
Liquid Asset Trust (the Fund), a business trust operating as an open end 
investment company, duly organized under the laws of the Commonwealth of 
Massachusetts and The Philadelphia National Bank (PNB), a national bank;

                                  WITNESSETH:

WHEREAS, the Fund desires to appoint The Philadelphia National Bank as custodian
of its Securities and cash, and The Philadelphia National Bank is willing to act
in such capacity upon the terms and conditions herein set forth; and

WHEREAS, The Philadelphia National Bank in its capacity as custodian hereunder 
will also collect and apply the dividends and interest on said Securities in the
manner and to the extent herein set forth;

NOW, THEREFORE, in consideration of the premises and of the mutual covenants 
herein contained, the parties hereto, intending to be legally bound, do hereby 
agree as follows:


SECTION 1.  The terms as defined in this Section wherever used in this 
Agreement, or in any amendment or supplement hereto, shall have the meanings 
herein specified unless the context otherwise requires.

CUSTODIAN:  The term Custodian shall mean The Philadelphia National Bank in its 
capacity as custodian under this Agreement.

PROPER INSTRUCTIONS:  For purposes of this Agreement the Custodian shall be 
deemed to have received Proper Instructions upon receipt of written, telephone 
or telegraphic instructions from a person or persons reasonably believed by the 
Custodian to be a person or persons authorized from time to time by the trustees
of the Fund or by the Board of Directors of an investment adviser for the Fund 
to give the particular class of instructions.  Telephone or telegraphic 
instructions shall be confirmed in writing by such person or persons as said 
Trustees or said Board of Directors shall have from time to time authorized to 
give the particular class of instructions in question.  The Custodian may act 
upon telephone or telegraphic instructions without awaiting receipt of written 
confirmation, and shall not be liable for Fund's or such investment adviser's 
failure to confirm such instructions in writing.

SECURITIES:  The term Securities shall mean bonds, debentures, notes, 
certificates of deposit, evidences of indebtedness, and other securities and 
investments from time to time owned by the Fund.
<PAGE>
 
SHAREHOLDERS: The term Shareholders shall mean the registered owners from time 
to time of the Shares of the Fund in accordance with the registry records 
maintained by the Fund or agents on its behalf.

SHARES: The term Shares of the Fund shall mean the shares of beneficial interest
of the Fund.

SECTION 2. The Fund shall from time to time file with the Custodian a certified 
copy of each resolution of its Board of Trustees authorizing the person or 
persons to give Proper Instructions (as defined in SECTION 1) and specifying the
class of instructions that may be given by each person to the Custodian under 
this Agreement, together with certified signatures of such persons authorized to
sign, which shall constitute conclusive evidence of the authority of the 
officers and signatories designated therein to act, and shall be considered in 
full force and effect with the Custodian fully protected in acting in reliance 
thereon until it receives written notice to the contrary; provided, however, 
that if the certifying officer is authorized to give Proper Instructions, the 
certification shall be also signed by a second officer of the Fund.

SECTION 3. The Fund hereby appoints the Custodian as custodian of the Securities
of the Fund and cash from time to time on deposit hereunder, to be held by the 
Custodian and applied as provided in this Agreement. The Custodian hereby 
accepts such appointment subject to the terms and conditions hereinafter 
provided. Such Securities and cash shall, however, be segregated from the assets
of others and shall be and remain the sole property of the Fund and the 
Custodian shall have only the bare custody thereof. The Securities held by the 
Custodian shall, unless payable to bearer, be registered in the name of the 
Custodian or in the name of its nominee. Securities, excepting bearer 
securities, delivered from time to time to the Custodian upon purchase or 
otherwise shall in all cases be in due form for transfer or already registered 
as above provided.

SECTION 4. The Fund will initially deposit with the Custodian the Securities 
owned by the Fund at the time this Agreement becomes effective. Thereafter the 
Fund will cause to be deposited with the Custodian additional Securities as the 
same are purchased or otherwise acquired from time to time.

The Fund will make an initial deposit of cash to be held and applied by the 
Custodian hereunder. Thereafter the Fund will cause to be deposited with the 
Custodian hereunder (i) the net proceeds of Securities sold from time to time 
and (ii) the applicable net asset value of Shares sold from time to time whether
representing initial issue, other stock or reinvestments of dividends and/or 
distributions payable to Shareholders.
<PAGE>
 
The Fund warrants that it shall keep all of its Securities, similar 
investments, cash proceeds and other cash assets of the Fund in the custody of 
the Custodian, except where permitted to otherwise keep, deposit, loan, pledge 
or otherwise dispose of or maintain such assets in accordance with applicable 
law.

SECTION 5. The Custodian will collect from time to time the dividends and 
interest on the Securities held by it hereunder and will deposit the same in the
Fund's account. The Custodian is authorized to advance or pay out of said
account accrued interest on bonds purchased and dividends on securities sold and
like items. In the event that any dividends or interest payments are received by
the Fund, the Fund will endorse to the Custodian, or cause to be endorsed,
dividend and interest checks and will issue appropriate orders to the issuers of
the Securities to pay dividends and interest to the Custodian. Subject to proper
reserves for interest owing on Securities sold and like items, the Custodian
will disburse the money from time to time on deposit in the account to or upon
the order of the Fund as it may from time to time direct in accordance with this
Agreement.

SECTION 6. The Custodian is hereby authorized and directed to disburse cash from
time to time as follows:

     (a)  to pay the proper compensation and expenses of Custodian upon receipt 
of Proper Instructions;

     (b)  to transfer to the Transfer Agent or other dividend disbursing agent 
to pay dividends and/or distributions which may be authorized by the Fund upon 
receipt of Proper Instructions;

     (c)  to pay, or provide the Fund with money to pay, if any, taxes upon 
receipt of Proper Instructions;

     (d)  for the purpose of completing the purchase of Securities purchased by 
the Fund, upon receipt of (i) Proper Instructions specifying the Securities and 
stating the purchase price, and the name of the broker, investment banker or 
other party to or upon whose order the purchase price is to be paid; and (ii) 
upon receipt of such Securities by the Custodian or, in the case of a purchase 
effected through a Securities System, in accordance with Section 8 hereof;

     (e)  for the purpose of redeeming or purchasing Shares upon receipt of 
Proper Instructions stating the applicable redemption amounts payable, to the 
Transfer Agent or other appropriate party;
<PAGE>

Department of the Treasury and certain Federal agencies, collectively referred 
to herein as "Securities System" in accordance with applicable Federal Reserve 
Board and Securities and Exchange Commission rules and regulations, if any, and 
subject to the following provisions:

     1)   The Custodian may keep Securities of the Fund in a Securities System
          provided that such Securities are represented in an account
          ("Account") of the Custodian in the Securities System which shall not
          include any assets of the Custodian other than assets held as a
          fiduciary, custodian, or otherwise for customers.

     2)   The records of the Custodian with respect to Securities of the Fund
          which are maintained in a Securities System shall identify by book-
          entry those Securities belonging to the Fund.

     3)   The Custodian shall pay for Securities purchased for the account of
          the Fund upon (i) receipt of advice from the Securities System that
          such Securities have been transferred to the Account, and (ii) the
          making of an entry on the records of the Custodian to reflect such
          payment and transfer for the account of the Fund. The Custodian shall
          transfer Securities sold for the account of the Fund upon (i) receipt
          of advice from the Securities System that payment for such Securities
          has been transferred to the Account, and (ii) the making of an entry
          on the records of the Custodian to reflect such transfer and payment
          for the account of the Fund. Copies of all advices from the Securities
          System of transfers of Securities for the account of the Fund shall
          identify the Fund, be maintained for the Fund by the Custodian and be
          provided to the Fund at its request. The Custodian shall furnish the
          Fund confirmation of each transfer to or from the account of the Fund
          in the form of a written advice or notice and shall furnish to the
          Fund copies of daily transaction sheets reflecting each day's
          transaction for the account of the Fund on the next business day.
<PAGE>
 
     4)   The Custodian shall provide the Fund with any report obtained by the
          Custodian on the Securities System's internal accounting control and
          procedures for safeguarding securities deposited in the Securities
          System.

     5)   The Custodian shall have received an initial certificate of the
          Secretary or an Assistant Secretary that the Trustees of the Fund have
          approved the initial use of a particular Securities System and the
          Custodian shall receive an annual certificate of the Secretary or an
          Assistant Secretary that the Trustees have reviewed the use by the
          Fund of such Securities System, as required in each case by Rule 17f-4
          under the Investment Company Act of 1940, as amended.

     6)   Anything to the contrary in this Agreement notwithstanding, the
          Custodian shall be liable to the Fund for any loss or damage to the
          Fund resulting from use of the Securities System by reason of any
          negligence, misfeasance or misconduct of the Custodian or any of its
          agents or of any of its or their employees or from any failure of the
          Custodian or any such agent to enforce effectively such rights as it
          may have against the Securities System; at the election of the Fund,
          it shall be entitled to be subrogated to the rights of the Custodian
          with respect to any claim against the Securities System or any other
          person which the Custodian may have as a consequence of any such loss
          or damage if and to the extent that the Fund has not been made whole
          for any such loss or damage.

SECTION 9.  The Custodian's compensation shall be as set forth in Schedule A 
hereto attached, or as shall be set forth in amendments to such schedule 
approved by the Fund and the Custodian.

SECTION 10.  The Custodian shall forward to the Fund proxies, proxy statements, 
annual reports, conversion notices, call notices, or other notices or written 
materials sent to the registered owners of securities and actually received by 
the Custodian (hereafter referred to as "notices and materials"), excluding only
certificates representing securities and dividend and interest payments. 
Responsibility for taking action thereon is the sole responsibility of the Fund 
and its investment advisor, and not the responsibility of the Custodian. Upon 
actual receipt by the Custodian or warrants or rights issued in connection with 
the assets of the Fund, the Custodian shall enter on its ledgers appropriate 
notations indicating such receipt and shall forward notice thereof to the Fund, 
but shall have no obligation whatsoever to take any action of any kind with 
respect to such warrants or rights except upon receipt of Proper Instructions 
authorizing the exercise or sale of such warrants or rights.
<PAGE>
 
SECTION 11. The Custodian assumes only the usual duties or obligations normally
performed by custodians of mutual funds. It specifically assumes no
responsibility for the management, investment or reinvestment of the Securities
from time to time owned by the Fund whether or not on deposit hereunder, it
being understood that the responsibility for the proper and timely management,
investment and reinvestment of said Securities shall be that of the Fund and its
investment advisors.

In connection with its functions under this Agreement, the Custodian shall:

     (a) obtain a "due bill" for dividends, interest or other distributions of
the issuer, due the purchaser in connection with Securities delivered to the
Custodian;
 
     (b) render to the Fund a daily report of all monies received or paid on 
behalf of the Fund and such listings of Securities held by the Custodian for the
account of the Fund as may from time to time be requested by the Fund.

     (c) execute ownership and other certificates and affidavits for all Federal
and State tax purposes in connection with the collection of bond and note
coupons;

     (d) present for payment on the date of payment all coupons and other period
income items requiring presentation;

     (e) monitor and record the collection of funds in accounts maintained by
the Custodian, in the name of the Fund on the same day as received;

     (f) in accordance with the manager's directions as to allocation of the
securities to separate portfolios designated by the Fund, the Custodian shall
maintain records showing the respective securities comprising each such
portfolio.

     (g) create, maintain and retain all records relating to its activities and 
obligations under this Agreement in such manner as will meet the obligations of 
the Fund with respect to said Custodian activities and obligations under
generally accepted accounting principles. All records maintained by the
Custodian in connection with the performance of its duties under this Agreement
will remain the property of the Fund and in the event of termination of this
Agreement will be relinquished to the Fund.

If the Custodian does not receive payment for items due under subsection (a), 
(d), or (e) within a reasonable time after it has made proper demand for the 
same, it shall so notify the Fund in writing, including copies of all demand
letters, any written responses thereto, and memoranda of all oral responses
thereto and to telephonic demands, and await Proper Instructions; the Custodian
shall not be obliged to take legal action for collection except by its consent
and unless and until reasonably indemnified to its satisfaction. The Custodian
shall also notify the Fund as soon as
<PAGE>
 
reasonably practicable whenever income due on Securities is not collected in due
course.

The Custodian shall not be liable for any taxes, assessments, or governmental 
charges which may be levied or assessed upon the Securities held by it 
hereunder, or upon the income therefrom or otherwise whatsoever. The Custodian 
may pay any such tax, assessment or charge and reimburse itself out of the 
monies of the Fund or out of the Securities held hereunder.

SECTION 12.  No liability of any kind shall be attached to or incurred by the 
Custodian by reason of its custody of the funds, assets, or shares held by it 
from time to time under this Agreement, or otherwise by reason of its position 
as custodian hereunder except only for its own negligence, bad faith, or willful
misconduct in the performance of its duties as specifically set forth in the 
Agreement. Without limiting the generality of the foregoing sentence, the 
Custodian:

     (a)  may rely upon the advice of counsel, who may be counsel for the Fund 
or for the Custodian, and upon statements or accountants, brokers and other 
persons believed by it in good faith to be expert in the matters upon which they
are consulted; and for any action taken or suffered in good faith based upon 
such advice or statements the Custodian shall not be liable to anyone;

     (b)  shall not be liable for anything done or suffered to be done in good 
faith in accordance with any request or advice of, or based upon information 
furnished by, the Fund or its authorized officers or agents;

     (c)  is authorized to accept a certificate of the Secretary or Assistant 
Secretary of the Fund, or Proper Instructions, to the effect that a resolution 
in the form submitted has been duly adopted by its Board of Trustees or by the 
Shareholders, as conclusive evidence that such resolution has been duly adopted 
and is in full force and effect;

     (d)  may rely and shall be protected in acting upon any signature, written 
(including telegraph or other mechanical) instructions, request, letter of 
transmittal, certificate, opinion of counsel, statement, instrument, report, 
notice, consent, order, or other paper or document reasonably believed by it to 
be genuine and to have been signed, forwarded or presented by the purchaser, 
Fund or other proper party or parties.

SECTION 13.  The Fund, its successors and assigns hereby indemnify and hold 
harmless the Custodian, its successors and assigns, of and from any and all 
liability whatsoever arising out of or in connection with the Custodian's 
status, acts, or omissions under this Agreement, except only for liability 
arising out of the Custodian's own negligence, bad faith, or willful misconduct 
in the performance of 
<PAGE>
 
its duties specifically set forth in this Agreement. Without limiting the 
generality of the foregoing, the Fund, its successors and assigns do hereby 
fully indemnify and hold harmless the Custodian, it successors and assigns, from
any and all loss, liability, claims, demand, actions, suits and expenses of any 
nature as the same may arise from the failure of the Fund to comply with any 
law, rule, regulation or order of the United States, any State or any other 
jurisdiction, governmental authority, body, or board relating to the sale, 
registration, qualification of shares of any beneficial interest in the Fund, or
from the failure of the Fund to perform any duty or obligation under this 
Agreement.

Upon written request of the Custodian, the Fund shall assume the entire defense 
of any claim subject to the foregoing indemnity, or the joint defense with the 
Custodian of such claim, as the Custodian shall request. The indemnities and 
defense provisions of this SECTION 13 shall indefinitely survive termination of 
this Agreement.

SECTION 14.  The Custodian shall provide the Fund, at such times as the Fund may
reasonably require, with accountants' reports on the accounting system, internal
accounting control and procedures for safeguarding securities, including 
securities deposited and/or maintained in a Securities System, relating to the 
services provided by the Custodian under this Agreement; such reports, which 
shall be of sufficient scope and in sufficient detail to provide reasonable 
assurance that any material inadequacies would be disclosed, shall state in 
detail material inadequacies disclosed by such examination, and, if there are no
such inadequacies, shall so state. Notwithstanding the foregoing the Custodian 
shall not be required by the provisions of this Section 14 to have such a 
report, which is not required for other purposes, prepared by independent public
accountants, unless the Fund agrees to reimburse the Custodian for the 
reasonable charges of such independent public accountants for preparing such 
report.

SECTION 15.  This Agreement may be amended from time to time without notice to 
or approval of the Shareholders by a supplemental agreement executed by the Fund
and the Custodian and amending and supplementing this Agreement in the manner 
mutually agreed.

SECTION 16.  Either the Fund or the Custodian may give one hundred twenty (120) 
days written notice to the other of the termination of this Agreement, such 
termination to take effect at the time specified in the notice. In case such 
notice of termination is given either by the Fund or by the Custodian, the 
Trustees of the Fund shall, by resolution duly adopted, promptly appoint a 
Successor Custodian which Successor Custodian shall be a bank, trust company, or
a bank and trust company in good standing, with legal capacity to accept custody
of the securities of a mutual fund. Upon receipt of written notice from the Fund
of the appointment of such successor and upon receipt of Proper Instructions, 
the Custodian shall deliver such 
<PAGE>
 
Securities and cash as it may then be holding hereunder directly to and only to
the Successor Custodian. Unless or until a Successor Custodian has been
appointed as above provided, the Custodian then acting shall continue to act as
Custodian under this Agreement.

Every Successor Custodian appointed hereunder shall execute and deliver an
appropriate written acceptance of its appointment and shall thereupon become
vested with the rights, powers, obligations and custody of its predecessor
Custodian. The Custodian ceasing to act shall nevertheless, upon request of the
Fund and the Successor Custodian and upon payment of its charges and
disbursements, execute an instrument in form approved by its counsel
transferring to the Successor Custodian all the predecessor Custodian's rights,
duties, obligations and custody.

In case the Custodian shall consolidate with or merge into any other
corporation, the corporation remaining after or resulting from such
consolidation or merger shall ipso facto, without the execution of filing of any
papers or other documents, succeed to and be substituted for the Custodian with
like effect as though originally named as such.


SECTION 17. This Agreement shall take effect when assets of the Fund are first 
delivered to the Custodian.


SECTION 18. This Agreement may be executed in two or more counterparts, each of 
which when so executed shall be deemed to be an original, but such counterparts 
shall together constitute but one and the same instrument.


SECTION 19. The Custodian may, at any time or times appoint (and may at any time
remove) and other bank or trust company which is itself qualified under the 
Investment Company Act of 1940, as amended, to act as a custodian, as its agent 
to carry out such of the provisions of this Agreement as the Custodian may from 
time to time direct, provided, however, that the appointment of such agent shall
not relieve the Custodian of any of its responsibilities under this Agreement.


SECTION 20. A copy of the Declaration of Trust of the Fund is on file with the 
Secretary of The Commonwealth of Massachusetts, and notice is hereby given that 
this instrument is executed on behalf of the Trustees of the Fund as Trustees 
and not individually and that the obligations of this instrument are not binding
upon any of the Trustees, officers or shareholders of the Fund individually but 
binding only upon the assets and property of the Fund.


SECTION 21. The Custodian shall create and maintain all records relating to its
activities and obligations under this Agreement in such manner as will meet the
obligations of the Fund under the Investment Company Act of 1940, with
particular attention to Section
<PAGE>
 
31 thereof and Rules 31a-1 and 31a-2 thereunder, applicable Federal and state 
tax laws and any other law or administrative rules or procedures which may be 
applicable to the Fund.

Subject to security requirements of the Custodian applicable to its own
employees having access to similar records within the Custodian and such
regulations as to the conduct of such monitors as may be reasonably imposed by
the Custodian after prior consultation with an officer of the Fund the books and
records of the Custodian pertaining to its actions under this Agreement shall be
open to inspection and audit at any reasonable times by officers of, attorneys
for, and auditors employed by, the Fund.

SECTION 22.  Nothing contained in this Agreement is intended to or shall require
the Custodian in any capacity hereunder to perform any functions or duties on 
any holiday or other day of special observance on which the Custodian is closed.
Functions or duties normally scheduled to be performed on such days shall be 
performed on, and as of, the next business day the Custodian is open.

SECTION 23.  This Agreement shall extend to and shall be binding upon the 
parties hereto and their respective successors and assigns; provided, however, 
that this Agreement shall not be assignable by the Fund without the written 
consent of the Custodian, or by the Custodian without the written consent of the
Fund, authorized or approved by a resolution of its Board of Trustees.

IN WITNESS WHEREOF, the Fund and the Custodian have caused this Agreement to be 
signed by their respective officers as of the day and year first above written.

Board and Securities and Exchange Commission rules and regulations, if any, and 
subject to the following provisions:

     1)  The Secondary Custodian may keep Securities of the Fund in a Securities
         System provided that such Securities

                                      -5-
<PAGE>
 
         are represented in an account ("Account") of the Secondary Custodian in
         the Securities System which shall not include any assets of the
         Secondary Custodian other than assets held as a fiduciary, custodian,
         or otherwise for customers.

     2)  The records of the Secondary Custodian with respect to Securities of 
         the Fund which are maintained in a Securities System shall identify by 
         book-entry those Securities belonging to the Fund.

     3)  The Secondary Custodian shall pay for Securities purchased for the 
         account of the Fund upon (i) receipt of advice from the Securities
         System that such Securities have been transferred to the Account, and

         Securities for the account of the Fund shall identify the Fund, be
         maintained for the Fund by the Secondary Custodian and be provided to
         the Fund at its request. The Secondary Custodian shall furnish the Fund
         confirmation of each transfer to or from the account of the Fund in the
         form of a written advice or notice and shall furnish to the Fund copies

     4)  The Secondary Custodian shall provide the Fund with any report obtained

                                      -6-

     6)   Anything to the contrary in this Agreement notwithstanding, the
          Secondary Custodian shall be liable to the Fund for any loss or damage
          to the fund resulting from use of the Securities System by reason of
          any negligence, misfeasance or misconduct of the Secondary Custodian
          or any of its agents or of any of its or their employees or from any
          failure of the Secondary Custodian or any such agent to enforce
          effectively such rights as it may have against the Securities System;
          at the election of the Fund, it shall be entitled to be subrogated to
          the rights of the Secondary Custodian with respect to any claim
          against the Securities System or any other person which the Secondary
          Custodian may have as a consequence of any such loss or damage if and
          to the extent that the Fund has not been made whole for any such loss
          or damage.

SECTION 9.  The Secondary Custodian's compensation shall be as negotiated 
between the Secondary Custodian and the Fund.

SECTION 10.  The Secondary Custodian shall forward to the Fund proxies, proxy 
statements, annual reports, conversion notices, call notices, or other notices 
or written materials sent to the registered owners of securities and actually 
received by the Secondary Custodian (hereafter referred to as "notices and 
materials"), excluding only certificates representing securities and dividend 
and interest payments. Responsibility for taking action thereon is the sole 
responsibility of the Fund and its investment adviser, and not the
responsibility of the Secondary Custodian. Upon actual receipt by the Secondary
Custodian of warrants or rights issued in connection with the assets of the
Fund, the Secondary Custodian shall enter on its ledgers appropriate notations
indicating such receipt and shall forward notice thereof to the Fund, but shall
have no obligation whatsoever to take any action of any kind with respect to
such warrants or rights except upon receipt of Proper Instructions authorizing
the exercise or sale of such warrants or rights.

SECTION 11.  The Secondary Custodian assumes only the usual duties or 
obligations normally performed by custodians of mutual funds. It specifically 
assumes no responsibility for the management, investment or reinvestment of the 
Securities from time to time owned by the Fund whether or not on deposit 
hereunder, it being understood that the responsibility for the proper and timely
management, investment and reinvestment of said Securities shall be that of the
Fund and its investment advisers.

                                      -7-

In connection with its functions under this Agreement, the Secondary Custodian 
shall:

     (a)  obtain a "due bill" for dividends, interest or other distributions of 
the issuer, due the purchaser in connection with Securities delivered to the 
Secondary Custodian;

     (b)  render to the Fund a daily report of all monies received or paid on 
behalf of the Fund and such listings of Securities held by the Secondary 
Custodian for the account of the Fund as may from time to time be requested by 
the Fund.

     (c)  execute ownership and other certificates and affidavits for all 
Federal and State tax purposes in connection with the collection of bond and 
note coupons;

     (d)  present for payment on the date of payment all coupons and other

     (e)  monitor and record the collection of funds in accounts maintained by 
the Secondary Custodian, in the name of the Fund on the same day as received;

     (f)  in accordance with the manager's directions as to allocation of the 
securities to separate portfolios designated by the Fund, the Secondary 
Custodian shall maintain records showing the respective securities comprising 
each such portfolio.

     (g)  create, maintain and retain all records relating to its activities and
obligations under this Agreement in such manner as will meet the obligations of 
the Fund with respect to said Secondary Custodian activities and obligations 
under generally accepted accounting principles. All records maintained by the 
Secondary Custodian in connection with the performance of its duties under this 
Agreement will remain the property of the Fund and in the event of termination 
of this Agreement will be relinquished to the Fund.

If the Secondary Custodian does not receive payment for items due under 
subsection (a), (d), or (e) within a reasonable time after it has made proper 
demands for the same, it shall so notify the Fund in writing, including copies 
of all demand letters, any written responses thereto, and memoranda of all oral 
responses thereto and to telephonic demands, and await Proper Instructions; the 
Secondary Custodian shall not be obliged to take legal action for collection 
except by its consent and unless and until reasonably indemnified to its 
satisfaction. The Secondary Custodian shall also notify the Fund as soon as 
reasonably practicable whenever income due on Securities is not collected in due
course.

                                      -8-
<PAGE>
 
The Secondary Custodian shall not be liable for any taxes, assessments, or 
governmental charges, which may be levied or assessed upon the Securities held 
by it hereunder, or upon the income therefrom or otherwise whatsoever. The 
Secondary Custodian may pay any such tax, assessment or charge and reimburse 
itself out of the monies of the fund or out of the Securities held hereunder.

SECTION 12.  No liability of any kind shall be attached to or incurred by the 
Secondary Custodian by reason of its custody of the funds, assets, or shares 
held by it from time to time under this Agreement, or otherwise by reason of its
position as secondary custodian hereunder except only for its own negligence, 
bad faith, or willful misconduct in the performance of its duties as 
specifically set forth in the Agreement. Without limiting the generality of the 
foregoing sentence, the Secondary Custodian:

     (a)  may rely upon the advice of counsel, who may be counsel for the Fund
or for the Secondary Custodian, and upon statements of accountants, brokers and
other persons believed by it in good faith to be expert in the matters upon
which they are consulted; and for any action taken or suffered in good faith
based upon such advice or statements the Secondary Custodian shall not be liable
to anyone;

     (b)  shall not be liable for anything done or suffered to be done in good 
faith in accordance with any request or advice of, or based upon information 
furnished by, the Fund or its authorized officers or agents;

     (c)  is authorized to accept a certificate of the Secretary or Assistant 
Secretary of the Fund, or Proper Instructions, to the effect that a resolution 
in the form submitted has been duly adopted by its Board of Trustees or by the 
Shareholders, as conclusive evidence that such resolution has been duly adopted 
and is in full force and effect;

     (d)  may rely and shall be protected in acting upon any signature, written 
(including telegraph or other mechanical) instructions, request, letter of 
transmittal, certificate, opinion of counsel, statement, instrument, report, 
notice, consent, order, or other paper or document reasonably believed by it to 
be genuine and to have been signed, forwarded or presented by the purchaser, 
Fund or other proper party or parties.

SECTION 13.  The Fund, its successors and assigns hereby indemnify and hold 
harmless the Secondary Custodian, its successors and assigns, of and from any 
and all liability whatsoever arising out of or in connection with the Secondary

                                      -9-
     
<PAGE>
 
Custodian's status, acts, or omissions under this Agreement except only for 
liability arising out of the Secondary Custodian's own negligence, bad faith, or
willful misconduct in the performance of its duties specifically set forth in 
this Agreement. Without limiting the generality of the foregoing, the Fund, its 
successors and assigns do hereby fully indemnify and hold harmless the Secondary
Custodian, its successors and assigns, from any and all loss, liability, claims,
demand, actions, suits and expenses of any nature as the same may arise from the
failure of the Fund to comply with any law, rule, regulation or order of the
United States, any State of any other jurisdiction, governmental authority,
body, or board relating to the sale, registration, qualification of shares of
any beneficial interest in the Fund, or from the failure of the Fund to perform
any duty or obligation under this Agreement.

Upon written request of the Secondary Custodian, the Fund shall assume the 
entire defense of any claim subject to the foregoing indemnity, or the joint 
defense with the Secondary Custodian of such claim, as the Secondary Custodian 
shall request. The indemnities and defense provisions of this SECTION 13 shall 
indefinitely survive termination of this Agreement.

SECTION 14. The Secondary Custodian shall provide the Fund, at such times as the
Fund may reasonably require, with accountants' reports on the accounting system,
internal accounting control and procedures for safeguarding securities,
including securities deposited and/or maintained in a Securities System,
relating to the services provided by the Secondary Custodian under this
Agreement; such reports, which shall be of sufficient scope and in sufficient
detail to provide reasonable assurance that any material inadequacies would be
disclosed, shall state in detail material inadequacies disclosed by such
examination, and, if there are no such inadequacies, shall so state.
Notwithstanding the foregoing the Secondary Custodian shall not be required by
the provisions of this Section 14 to have such a report, which is not required
for other purposes, prepared by independent public accountants, unless the Fund
agrees to reimburse the Secondary Custodian for the reasonable charges of such
independent public accountants for preparing such report.

SECTION 15. This Agreement may be amended from time to time without notice to or
approval of the Shareholders by a supplemental agreement executed by the Fund 
and the Secondary Custodian and amending and supplementing this Agreement in the
manner mutually agreed.

SECTION 16. Either the Fund or the Secondary Custodian may give one hundred 
twenty (120) days written notice to the other of the 

                                     -10-
<PAGE>
 
termination of this Agreement, such termination to take effect at the time 
specified in the notice.

In case the Secondary Custodian shall consolidate with or merge into any other 
corporation, the corporation remaining after or resulting from such 
consolidation or merger shall ipso facto, without the execution of filing of any
papers or other documents, succeed to and be substituted for the Secondary 
Custodian with like effect as though originally named as such.

SECTION 17.  This Agreement shall take effect when assets of the Fund are first 
delivered to the Secondary Custodian.

SECTION 18.  This Agreement may be executed in two or more counterparts, each of
which when so executed shall be deemed to be an original, but such counterparts 
shall together constitute but one and the same instrument.

SECTION 19.  The Secondary Custodian may, at any time or times appoint (and may 
at any time remove) any other bank or trust company which is itself qualified 
under the Investment Company Act of 1940, as amended, to act as a custodian, as 
its agent to carry out such of the provisions of this Agreement as the Secondary
Custodian may from time to time direct, provided, however, that the appointment 
of such agent shall not relieve the Secondary Custodian of any of its 
responsibilities under this Agreement.

SECTION 20.  A copy of the Declaration of Trust of the Fund is on file with the 
Secretary of The Commonwealth of Massachusetts, and notice is hereby given that 
this instrument is executed on behalf of the Trustees of the Fund as Trustees 
and not individually and that the obligations of this instrument are not binding
upon any of the Trustees, officers or shareholders of the Fund individually but 
binding only upon the assets and property of the Fund.

SECTION 21.  The Secondary Custodian shall create and maintain all records 
relating to its activities and obligations under this Agreement in such manner 
as will meet the obligations of the Fund under the Investment Company Act of 
1940, with particular attention to Section 31 thereof and Rules 31a-1 and 31a-2 
thereunder, applicable Federal and State tax laws and any other law or 
administrative rules or procedures which may be applicable to the Fund.

                                     -11-
<PAGE>
 
Subject to security requirements of the Secondary Custodian applicable to its 
own employees having access to similar records within the Secondary Custodian 
and such regulations as to the conduct of such monitors as may be reasonably 
imposed by the Secondary Custodian after prior consultation with an officer of 
the Fund the books and records of the Secondary Custodian pertaining to its 
actions under this Agreement shall be open to inspection and audit at any 
reasonable times by officers of, attorneys for, and auditors employed by, the 
Fund.

SECTION 22.  This Agreement shall extend to and shall be binding upon the 
parties hereto and their respective successors and assigns; provided, however, 
that this Agreement shall not be assignable by the Fund without the written 
consent of the Secondary Custodian, or by the Secondary Custodian without the 
written consent of the Fund, authorized or approved by a resolution of its Board
of Trustees.

IN WITNESS WHEREOF, the Fund and the Secondary Custodian have caused this 
Agreement to be signed by their respective officers as of the day and year first
above written.

open-end investment company registered under the Investment Company Act of 1940,
as amended ("1940 Act"); and

     WHEREAS, the Trustees of the Trust have determined that there is a

                                  Rule 18f-3
                              Multiple Class Plan

                                March 22, 1993


          SEI Liquid Asset Trust (the "Trust"), a registered investment company
that currently consists of five separately-managed portfolios and which may
consist of additional portfolios in the future to the extent listed on Schedule
A hereto, (each a "Portfolio" and, collectively, the "Portfolios"), have elected
to rely on Rule 18f-3 under the Investment Company Act of 1940, as amended (the
"1940 Act") in offering multiple classes of units of beneficial interest
("shares") in each Portfolio.  The Plan sets forth the differences among
classes, including shareholder services, distribution arrangements, expense
allocations, and conversion or exchange options.

A.   Attributes of Share Classes

          The rights of each existing class of the Portfolios (i.e., Class A,
                                                               ----          
and Class D) shall be as set forth in the resolutions and related materials of
the Trust's Board adopted pursuant to the order dated September 9, 1993,
obtained by SEI Liquid Asset Trust, et al. (Inv. Co. Act Release No. IC-19698),
                                    -- ---                                     
and attached hereto as Exhibits A - C.

          With respect to any class of shares of a Portfolio created after the
date hereof, each share of a Portfolio will represent an equal pro rata interest
                                                               --- ----         
in the Portfolio and will have identical terms and conditions, except that: (i)
each new class will have a different class name (or other designation) that
identifies the class as separate from any other class; (ii) each class will
separately bear any distribution expenses ("distribution fees") in connection
with a plan adopted pursuant to Rule 12b-1 under the 1940 Act (a "Rule 12b-1
Plan"), and will separately bear any non-Rule 12b-1 Plan service payments
("service fees") that are made under any servicing agreement entered into with
respect to that class; (iii) each class may bear, consistent with rulings and
other published statements of position by the Internal Revenue Service, the
expenses of the Portfolio's operations which are directly attributable to such
class ("Class Expenses"); and (iv) shareholders of the class will have exclusive
voting rights regarding the Rule 12b-1 Plan and the servicing agreements
relating to such class, and will have separate voting rights on any matter
submitted to shareholders in which the interests of that class differ from the
interests of any other class.
<PAGE>
 
B.   Expense Allocations

          Expenses of each existing class and of each class created after the
date hereof shall be allocated as follows:  (i) distribution and shareholder
servicing payments associated with any Rule 12b-1 Plan or servicing agreement
relating to each class of shares are (or will be) borne exclusively by that
class; (ii) any incremental transfer agency fees relating to a particular class
are (or will be) borne exclusively by that class; and (iii) Class Expenses
relating to a particular class are (or will be) borne exclusively by that class.

          Until and unless changed by the  Board, the methodology and procedures
for calculating the net asset value of the various classes of shares and the
proper allocation of income and expenses among the various classes of shares
shall be as set forth in the "Report" rendered by Coopers & Lybrand L.L.P.

C.   Amendment of Plan; Periodic Review

          This Plan must be amended to properly describe (through additional
exhibits hereto or otherwise) each new class of shares approved by the Board
after the date hereof.

          The Board of the Corporation, including a majority of the independent
Directors, must periodically review this Plan for its continued appropriateness,
and must approve any material amendment of the Plan as it relates to any class
of any Portfolio covered by the Plan.

  discretion. Absent the waiver of management fees, management/advisory fees

The purpose of this table is to assist the investor in understanding the
various costs and expenses that may be directly or indirectly borne by
investors in the Portfolios. A person who purchases shares through a financial
institution may be charged separate fees by that institution. The information
set forth in the foregoing table and example relates only to the Portfolios'
Class A shares. The Treasury Securities Portfolio and Prime Obligation
Portfolio also offer ProVantage Funds shares, which are subject to the same
expenses except that ProVantage Funds shares bear sales loads and different
distribution costs. Additional information may be found under "The Manager and
Shareholder Servicing Agent", "The Adviser" and "Distribution".
Long-term shareholders may eventually pay more than the economic equivalent of
the maximum front-end sales charges otherwise permitted by the Rules of Fair
Practice (the "Rules") of the National Association of Securities Dealers, Inc.

DISTRIBUTION ___________________________________________________________________
                  SEI Financial Services Company (the "Distributor"), 680 East
                  Swedesford Road, Wayne, PA 19087, a wholly-owned subsidiary
                  of SEI, acts as distributor. Each class of the Trust has a
                  separate distribution plan for its Class A shares (the
                  "Class A Plan") pursuant to Rule 12b-1 under the Investment
                  Company Act of 1940, as amended (the "1940 Act").
                     As provided in the distribution agreement and Plan the
                  Trust pays the Distributor at an annual rate of up to .30%
                  of the average daily net assets of each Portfolio, provided
                  those expenses are permissible as to both type and amount
                  under a budget. The budget must be approved and monitored by
                  the Trustees, including those who are not interested persons
                  and have no financial interest in the Plan or any related
                  agreement ("Qualified Trustees").
                     Distribution related expenses reimbursable to the
                  Distributor under the budget include those related to the
                  costs of advertising and sales materials, the costs of
                  federal and state securities law registration, advertising
                  expenses and promotional and sales expenses including

                  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.
                     With respect to investments in 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 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.
                     Sales, exchange, or redemption of Portfolio shares is a
                  taxable transaction to the shareholder.

1 A charge, currently $10.00, is imposed on wires of redemption proceeds of the
  Portfolio's ProVantage Funds shares.
2 The operating expenses for the Prime Obligation Portfolio set forth in this
  table reflect the expenses expected to be incurred by that Portfolio's
  ProVantage Funds shares for the fiscal year ending June 30, 1995.
3 The Manager has contractually agreed to waive a portion of its fee in order
  to limit total operating expenses for ProVantage Funds shares of each
  Portfolio to not more than .84% of its average daily net assets. Absent these
  contractual provisions, management/advisory, 12b-1 fees and total operating
  expenses as a percentage of net assets, respectively, would have been .45%,
  .28% and .86% for the Treasury Securities Portfolio, and .45%, .28% and .86%
  for the Prime Obligation Portfolio. Additional information may be found under
  "The Manager and Shareholder Servicing Agent", "The Adviser" and

An investor in the ProVantage Fund
shares of the Portfolios would pay
the following expenses on a $1,000
investment assuming (1) imposition of
the maximum sales load (2) 5% annual
return and (3) redemption at the end
of each time period:

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 is to assist the investor in understanding the
various costs and expenses that may be directly or indirectly borne by
investors in ProVantage Funds shares of each Portfolio. A person who purchases
shares through an account with a financial institution may be charged separate
fees by that institution. The information set forth in the foregoing table and
example relates only to the ProVantage Funds shares. Each Portfolio also offers
Class A shares, which are subject to the same expenses, except there are no
sales charges, different distribution costs and no transfer agent costs.
Additional information may be found under "The Manager and Shareholder
Servicing Agent", "The Adviser" and "Distribution".
The rules of the Securities and Exchange Commission require that the maximum
sales charge be reflected in the above table. However, certain investors
qualify for reduced sales charges. See "Purchase of Shares".
Long-term shareholders may pay more than the economic equivalent of the maximum

                  Each Portfolio may not:
                  1. Purchase securities of any issuer (except securities
                     issued or guaranteed by the U.S. Government, its agencies
                     or instrumentalities) if as a result more than 5% of
                     total assets of the Portfolio would be invested in the
                     securities of such issuer. This limitation applies to 75%
                     of each Portfolio's total assets.
                  2. Purchase any securities which would cause more than 25%
                     of the total assets of the Portfolio, based on fair
                     market value at the time of such purchase, to be invested
                     in the securities of one or more issuers conducting their
                     principal business activities in the same industry,
                     provided that this limitation does not apply to
                     investments in (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 
AND SHAREHOLDER 
SERVICING AGENT ________________________________________________________________
 
                  SEI Financial Management Corporation (the "Manager"), 680
                  East Swedesford Road, Wayne, PA 19087, a wholly-owned
                  subsidiary of SEI Corporation ("SEI"), provides the Trust
                  with overall management services, regulatory reporting, all
                  necessary office space, equipment, personnel and facilities
                  and for acting as transfer agent, dividend disbursing agent,
                  and shareholder servicing agent.
                     The Manager is entitled to a fee, calculated daily and
                  paid monthly at an annual rate of .42% of the average daily
                  net assets of each of the Treasury Securities and Prime
                  Obligation Portfolios. The Manager 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 daily net assets of the ProVantage Funds
                  shares of each Portfolio on an annualized basis. For the
                  fiscal year ended June 30, 1994, each Portfolio paid the
                  Manager fees (shown here as a percentage of average daily
                  net assets after fee waivers) of .35%.
                     In addition, the Trust and the Manager have entered into
                  a separate transfer agent agreement with respect to the
                  ProVantage Funds under which the Manager is entitled to a
                  fee of .15% of the average daily net assets of each
                  Portfolio offering ProVantage Funds shares plus out-of-
                  pocket costs.

DISTRIBUTION ___________________________________________________________________
                  SEI Financial Services Company (the "Distributor"), 680 East
                  Swedesford Road, Wayne, PA 19087, a wholly-owned subsidiary
                  of SEI, acts as distributor. Each class of the Trust has a
                  separate distribution plan (individually, the "Class A Plan"
                  and "ProVantage Funds Plan"; collectively, the "Plans")
                  pursuant to Rule 12b-1 under the Investment Company Act of
                  1940, as amended (the "1940 Act").
                     As provided in the distribution agreement and Plan for
                  each class, the Trust pays the Distributor at an annual rate
                  of up to .30% of the average daily net assets of each
                  Portfolio, provided those expenses are permissible as to
                  both type and amount under a budget approved and monitored
                  quarterly by the Trustees, including those who are not
                  interested persons and have no financial interest in the
                  Plans or any related agreement ("Qualified Trustees").
                     Distribution related expenses reimbursable to the
                  Distributor under the budget include those related to the
                  costs of advertising and sales materials, the costs of
                  federal and state securities law registration, advertising
                  expenses and promotional and sales expenses including
                  expenses for travel, communication and compensation and
                  benefits for sales personnel. The Trust is not obligated to
                  reimburse the Distributor for any expenditures in excess of
                  the approved budget. Currently, the budget for each
                  Portfolio is set at an annual rate of .03% of its average
                  daily net assets. Distribution expenses not attributable to
                  a specific portfolio are allocated among each of the
                  portfolios of the Trust based on average net assets.
                     The ProVantage Funds Plan, in addition to providing for
                  the reimbursement payments described above, provides for
                  payments to the Distributor at an annual rate of .25% of
                  each Portfolio average daily net assets attributable to
                  ProVantage Funds shares. These additional 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 additional payments
                  may be used to compensate the Distributor for its services
                  in connection with distribution assistance or provision of
                  shareholder services, and some or all of it may be used to
                  pay financial institutions and intermediaries such as banks,
                  savings and loan associations, insurance companies, and
                  investment counselors, broker-dealers and the Distributor's
                  affiliates and subsidiaries for services or reimbursement of
                  expenses incurred in connection with distribution assistance
                  or provision of shareholder services. If the Distributor's
                  expenses are less than its fees under the ProVantage Funds
                  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 additional "compensation" payment
                  under the ProVantage Funds Plan at a rate of only .20% of
                  each Portfolio's average daily net assets, on an annualized
                  basis, attributable to ProVantage Funds shares.

                     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 the
                  sales charge it receives or from any other source available
                  to it. 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.
                     The Trust may also execute brokerage or other agency
                  transactions through the Distributor for which the
                  Distributor may receive usual and customary compensation.
                  The Trust intends to operate the Plans in accordance with
                  their terms and with the NASD Rules concerning sales
                  charges.
 
PERFORMANCE ____________________________________________________________________
                  For any Portfolio, the performance of the ProVantage Funds
                  shares will normally be lower than the performance on the
                  Class A shares of that Portfolio because of additional
                  distribution and transfer agent expenses charged to
                  ProVantage Funds shares.
                     From time to time, each Portfolio may advertise its
                  "current yield" and "effective compound yield". These
                  figures are based on historical earnings and are not
                  intended to indicate future performance. No representation
                  can be made concerning actual future yields or returns. The
                  "current yield" of a Portfolio refers to the income
                  generated by an investment over a seven-day period which is
                  then "annualized". That is, the amount of income generated
                  by the investment during that week is assumed to be
                  generated each week over a 52-week period and is shown as a
                  percentage of the investment. The "effective yield" is
                  calculated similarly but, when annualized, the income earned
                  by an investment in the Portfolio 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 other mutual funds tracked by mutual fund rating
                  services (such as Lipper Analytical), financial and business
                  publications and periodicals, broad groups of comparable
                  mutual funds, to unmanaged indices which may assume
                  investment of dividends but generally do not reflect
                  deductions for administrative and management costs or to
                  other investment alternatives. The Portfolios may also quote
                  financial and business publications and periodicals as they
                  relate to fund management, investment philosophy and
                  investment techniques.

                  will be waived if all of the following conditions apply: (1)
                  the redemption is for not more than $5,000 worth of shares,
                  (2) the redemption check is payable to the shareholder(s) of
                  record, and (3) the redemption check is mailed to the
                  shareholder(s) at his or her address of record. The Trust
                  and the Transfer Agent reserve the right to amend these
                  requirements without notice.
Telephone/Wire    Redemption orders may be placed by telephone. Neither the
Instructions      Trust nor the Transfer Agent will be responsible for any
                  loss, liability, cost or expense for acting upon wire
                  instructions or upon telephone instructions that it
                  reasonably believes to be genuine. The Trust and the 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, and you experience
                  difficulties placing redemption orders by telephone, you may
                  wish to consider placing your order by other means.
Systematic        Please note that if withdrawals exceed income dividends,
Withdrawal Plan   your invested principal in the account will be depleted.
("SWP")           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      An account may be closed by providing written notice to the
your Account      Transfer Agent. You may also close your account by telephone
                  if you have previously elected telephone options on your
                  account application.
 
GENERAL 
INFORMATION ____________________________________________________________________
The Trust         SEI 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. Shareholders may purchase shares
                  in Portfolios through two separate classes: Class A and
                  ProVantage Funds, which provide for variation in
                  distribution and transfer agent costs, voting rights,
                  dividends, and the imposition of a sales charge on the
                  ProVantage Funds. This Prospectus offers the ProVantage
                  Funds shares of the Trust's Treasury Securities Portfolio
                  and Prime Obligation Portfolio (the "Portfolios"). In
                  addition to the Portfolios, the Trust consists of the
                  following portfolios: Government Securities Portfolio,
                  Institutional Cash Portfolio, and Money Market Portfolio.
                  Additional information pertaining to the Trust may be

                  received by the Trust 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
                  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   The management and affairs of the Trust are supervised by
Trust             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. 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 information
                  semiannually and audited financial statements annually. The
                  Trust furnishes proxy statements and other reports to
                  shareholders of record.
Shareholder       Shareholder inquiries should be directed to the Manager, SEI
Inquiries         Financial Management Corporation, P.O. Box 451, Wayne, PA,
                  19087.
Dividends         The dividends of ProVantage Funds shares will normally be
                  lower than on Class A shares of each Portfolio because of
                  the additional distribution and transfer agent expenses
                  charged to ProVantage Funds shares. Substantially all of the
                  net investment income (exclusive of capital gains) of each
                  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, if any, are
                  distributed at least annually.
                     Shareholders in the Portfolios 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 Portfolios are paid by
                  the Portfolios 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.

                                ProVantage Funds


     WHEREAS, SEI Liquid Asset Trust (the "Trust") is engaged in business as an
open-end investment company registered under the Investment Company Act of 1940,
as amended ("1940 Act"); and

     WHEREAS, the Trustees of the Trust have determined that there is a
reasonable likelihood that the following Distribution Plan will benefit the
Trust's ProVantage Funds Class and the owners of units of beneficial interest
("Shareholders") in the Trust's ProVantage Funds Class;

     NOW, THEREFORE, the Trustees of the Trust hereby adopt this Distribution
Plan pursuant to Rule 12b-1 under the 1940 Act.

     Section 1.  The Trust has adopted this ProVantage Funds Distribution Plan
     ----------

issuer.

     Section 2.  The Trust may incur expenses for the items stipulated in
     ----------                                                          
Section 3 of this Plan in an amount equal to .30% of the average daily net
assets of the ProVantage Funds of the Portfolios.  All expenditures pursuant to
this Plan shall be made only pursuant to authorization by the President, any
Vice President or the Treasurer of the Trust.  If there should be more than one
series of Trust shares, expenses incurred pursuant to this Plan shall be

net asset values, unless otherwise determined by a majority of the Qualified
Trustees.

In addition, the Trust will pay the Distributor a fee on the ProVantage Funds of
the Portfolios up to the amount set forth on Exhibit A.  The Distributor may use
this fee for (i) compensation for it 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.

limited to, the following:


     (a) The incremental printing costs incurred in producing for and
         distributing to

by a vote of at least a majority of the outstanding voting securities of the
Trust's ProVantage Funds Class; and (b) together with any related agreements, by
votes of the majority of both (i) the Trustees of the Trust and (ii) the

specifically approved at least annually in the manner provided in Part (b) of
Section 4 herein for the approval of this Plan.

     Section 6.  Any person authorized to direct the disposition of monies paid

or payable by the Trust pursuant to this Plan or any related agreement shall
provide to the Trustees of the Trust, at least quarterly, a written report of
the amounts so expended and the purposes for which such expenditures were made.

     Section 7.  This Plan may be terminated at any time by the vote of a
     ----------
