This Prospectus concisely sets forth information about the above-referenced
funds 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 September 30, 1997 has been filed
with the Securities and Exchange Commission (the "SEC") and is available upon
request and without charge by writing the distributor, SEI Investments
Distribution Co., Oaks, Pennsylvania 19456, or by calling 1-800-342-5734. The
Statement of Additional Information is incorporated by reference into this
Prospectus.
    
 
   
SEI Institutional Investments Trust ("SIIT" or the "Trust") is an open-end
management investment company that offers certain institutions with investable
pools of assets that have signed an Investment Management Agreement with SEI
Investments Management Corporation a convenient means of investing in
professionally managed diversified and non-diversified portfolios of securities.
    
 
THE HIGH YIELD BOND FUND INVESTS PRIMARILY, AND MAY INVEST ALL OF ITS ASSETS, IN
LOWER RATED BONDS, COMMONLY REFERRED TO AS "JUNK BONDS." THESE SECURITIES ARE
SPECULATIVE AND ARE SUBJECT TO GREATER RISK OF LOSS OF PRINCIPAL AND INTEREST
THAN ARE INVESTMENTS IN HIGHER RATED BONDS. BECAUSE INVESTMENT IN SUCH
SECURITIES ENTAILS GREATER RISKS, INCLUDING RISK OF DEFAULT, AN INVESTMENT IN
THE HIGH YIELD BOND FUND SHOULD NOT CONSTITUTE A COMPLETE INVESTMENT PROGRAM AND
MAY NOT BE APPROPRIATE FOR ALL INVESTORS. INVESTORS SHOULD CAREFULLY CONSIDER
THE RISKS POSED BY AN INVESTMENT IN THE HIGH YIELD BOND FUND BEFORE INVESTING.
SEE "INVESTMENT OBJECTIVES AND POLICIES," "GENERAL INVESTMENT POLICIES AND RISK
FACTORS -- RISK FACTORS RELATING TO INVESTING IN LOWER RATED SECURITIES" AND THE
"APPENDIX."
 
- --------------------------------------------------------------------------------
 
   
 THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
 EXCHANGE COMMISSION, NOR HAS THE SECURITIES AND EXCHANGE COMMISSION PASSED
 UPON THE ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE
 CONTRARY IS A CRIMINAL OFFENSE.
    
 
 THE TRUST'S SHARES ARE NOT DEPOSITS OR OBLIGATIONS OF, OR GUARANTEED OR
 ENDORSED BY, ANY BANK. THE TRUST'S 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.

ELIGIBLE INVESTORS
               _________________________________________________________________
 
   
                     Eligible investors are principally institutions that have
                     investable pools of assets, including defined benefit
                     plans, defined contribution plans, health care defined
                     benefit plans and board-designated funds, insurance
                     operating funds, foundations, endowments, public plans and
                     Taft-Hartley plans and have entered into an Investment
                     Management Agreement (the "Agreement") with SEI Investments
                     Management Corporation ("SIMC")(collectively, "Eligible
                     Investors").
    
 
   
                           Pursuant to the Agreement, SIMC will consult with
                     each Eligible Investor to define its investment objectives,
                     desired returns and tolerance for risk, and to develop a
                     plan for the allocation of assets among different asset
                     classes. The Agreement sets forth the fee to be paid to
                     SIMC, which is ordinarily expressed as a percentage of the
                     Eligible Investor's assets managed by SIMC. This fee, which
                     is negotiated by the Eligible Investor and SIMC, may
                     include a performance based fee or a fixed-dollar fee for
                     certain specified services. Either the Eligible Investor or
                     SIMC may terminate the Agreement upon written notice as
                     provided in the Agreement.
    
 
   
GENERAL MANAGEMENT OF
THE FUNDS ______________________________________________________________________
    
 
   
                     SIMC (the "Manager") is a wholly-owned subsidiary of SEI
                     Investments Company ("SEI Investments"), a financial
                     services company. The principal business address of SIMC
                     and SEI Investments is Oaks, Pennsylvania, 19456. SEI
                     Investments was founded in 1968, and is a leading provider
                     of investment solutions to banks, institutional investors,
                     investment advisers and insurance companies. Affiliates of
                     SIMC have provided consulting advice to institutional
                     investors for more than 20 years, including advice
                     regarding selection and evaluation of money managers. SIMC
                     currently serves as manager to more than 43 investment
                     companies, including more than 325 funds, with more than
                     $93.9 billion in assets as of May 31, 1997.
    
 
   
                           SIMC is the investment Manager for each of the Funds,
                     and operates as a "manager of managers." As Manager, SIMC
                     oversees the investment advisory services
    
 
                                                                               5

                     provided to the Funds and manages the cash portion of the
                     Funds' assets. Pursuant to separate sub-advisory agreements
                     with SIMC, and under the supervision of the Manager and the
                     Board of Trustees, a number of sub-advisers (the "Money
                     Managers") are responsible for the day-to-day investment
                     management of all or a discrete portion of the assets of
                     the Funds. Money Managers are selected for the Funds based
                     primarily upon the research and recommendations of SIMC,
                     which evaluates quantitatively and qualitatively a Money
                     Manager's skills and investment results in managing assets
                     for specific asset classes, investment styles and
                     strategies.
    
 
   
                           Subject to Board review, SIMC allocates and, when
                     appropriate, reallocates the Funds' assets among Money
                     Managers, monitors and evaluates Money Manager performance,
                     and oversees Money Manager compliance with the Funds'
                     investment objectives, policies and restrictions. SIMC HAS
                     ULTIMATE RESPONSIBILITY FOR THE INVESTMENT PERFORMANCE OF
                     THE FUNDS DUE TO ITS RESPONSIBILITY TO OVERSEE MONEY
                     MANAGERS AND RECOMMEND THEIR HIRING, TERMINATION AND
                     REPLACEMENT.
    
 
   
                           SIMC and the Trust have obtained an exemptive order
                     from the Securities and Exchange Commission (the "SEC")
                     that permits SIMC, with the approval of the Trust's Board
                     of Trustees, to retain Money Managers unaffiliated with
                     SIMC for the Funds without submitting the Money Manager
                     agreements to a vote of the Fund's shareholders. The
                     exemptive relief permits SIMC to disclose only the
                     aggregate amount payable by SIMC to the Money Managers
                     under all such Money Manager agreements for each Fund. The
                     Funds will notify shareholders in the event of any addition
                     or change in the identity of its Money Managers.
    
 
   
                           For its management services, SIMC is entitled to a
                     fee, which is calculated daily and paid monthly, at the
                     following annual rates (shown as a percentage of the
                     average daily net assets of each Fund): Large Cap Fund,
                     .40%; Small Cap Fund, .65%; Core Fixed Income Fund, .30%;
                     High Yield Bond Fund, .49%; International Fixed Income
                     Fund, .45%; Emerging Markets Equity Fund, 1.05%; and
                     International Equity Fund, .51%. SIMC pays the Money
                     Managers a fee out of its advisory fee, which fee is based
                     on a percentage of the average monthly market value of the
                     assets managed by each Money Manager.
    
 
   
                           For the fiscal year ended May 31, 1997, the Large
                     Cap, Small Cap, Core Fixed Income and International Equity
                     Funds paid management fees, after fee waivers, of .24%,
                     .49%, .12% and .35%, respectively, of their average daily
                     net assets. The High Yield Bond, International Fixed Income
                     and Emerging Markets Equity Funds had not commenced
                     operations as of May 31, 1997.
    
 
   
                           SEI Fund Management ("SEI Management" or the
                     "Administrator") provides the Fund with overall
                     administrative services, regulatory reporting, all
                     necessary office space, equipment, personnel and
                     facilities, and acts as dividend disbursing agent. SEI
                     Management also serves as transfer agent (the "Transfer
                     Agent") for the Funds. For these administrative services,
                     SEI Management is entitled to a fee, which is calculated
                     daily and paid monthly, at an annual rate of .05% of the
                     average daily net assets of each Fund.
    
 
                                                                               6

                     SIMC and SEI Management have agreed, on a voluntary basis,
                     to waive a portion of their Management/Administration Fees
                     and/or reimburse Other Expenses to the extent necessary to
                     keep Total Operating Expenses from exceeding current
                     levels. The Total Operating Expenses reflect current fee
                     waivers.
    
 
   
                           For the fiscal year ended May 31, 1997, the Large
                     Cap, Small Cap, Core Fixed Income and International Equity
                     Funds paid administrative fees, after fee waivers, of .02%,
                     .02%, .02% and .03%, respectively, of their average daily
                     net assets. The High Yield Bond, International Fixed Income
                     and Emerging Markets Equity Funds had not commenced
                     operations as of May 31, 1997.
    
 
   
                           SEI Investments Distribution Co. (The "Distributor")
                     serves as each Fund's distributor pursuant to a
                     distribution agreement (the "Distribution Agreement") with
                     the Trust. No compensation is paid to the Distributor under
                     the Distribution Agreement for distribution services for
                     the shares of any Fund.
    
 
   
                           The Fund may execute brokerage or other agency
                     transactions through the Distributor, for which the
                     Distributor may receive compensation.
    
 
   
                           The Distributor may, from time to time and at its own
                     expense, provide promotional incentives, in the form of
                     cash or other compensation, to certain financial
                     institutions whose representatives have sold or are
                     expected to sell significant amounts of the Funds' shares.

INVESTMENT OBJECTIVES
AND POLICIES
     ___________________________________________________________________________
 
                     Each Fund's investment objective and policies are set forth
                     below. See "General Investment Policies and Risk Factors"
                     for information about additional investment practices that
                     some or all of the Funds may employ.
 
LARGE CAP FUND
   
                     The investment objective of the Large Cap Fund is long-term
                     growth of capital and income.
    
 
                           Under normal market conditions, the Fund will invest
                     at least 65% of its total assets in equity securities of
                     large companies (i.e., companies with market
                     capitalizations
 
                                                                              17

                     of more than $1 billion at the time of purchase). Any
                     remaining assets may be invested in investment grade fixed
                     income securities, including variable and floating rate
                     securities, or in equity securities of smaller companies
                     that the Fund's Money Managers believe are appropriate in
                     light of the Fund's objective. The Fund may also purchase
                     illiquid securities, shares of other investment companies,
                     when-issued and delayed-delivery securities and zero coupon
                     obligations. The Fund may also borrow money and lend its
                     securities to qualified borrowers.
    
 
SMALL CAP FUND
   
                     The investment objective of the Small Cap Fund is capital
                     appreciation.
    
 
   
                           Under normal market conditions, the Fund will invest
                     at least 65% of its total assets in the equity securities
                     of smaller companies (i.e., companies with market
                     capitalizations of less than $1 billion at the time of
                     purchase). Any remaining assets may be invested in
                     investment grade fixed income securities, including
                     variable and floating rate securities, or in equity
                     securities of larger companies that the Fund's Money
                     Managers believe are appropriate in light of the Fund's
                     objective. The Fund may also purchase illiquid securities,
                     shares of other investment companies, when-issued and
                     delayed-delivery securities and zero coupon obligations.
                     The Fund may also borrow money and lend its securities to
                     qualified borrowers.
    
 
CORE FIXED INCOME FUND
   
                     The investment objective of the Core Fixed Income Fund is
                     current income consistent with the preservation of capital.
    
 
   
                           Under normal market conditions, the Fund will invest
                     at least 65% of its total assets in investment grade fixed
                     income securities.
    
 
   
                           The Fund may acquire all types of fixed income
                     securities issued by domestic and foreign private and
                     governmental issuers, including mortgage-backed and
                     asset-backed securities and variable and floating rate
                     securities. The Fund may invest not only in traditional
                     fixed income securities, such as bonds and debentures, but
                     in structured securities that make interest and principal
                     payments based upon the performance of specified assets or
                     indices. Structured securities include mortgage-backed
                     securities such as pass-through certificates,
                     collateralized mortgage obligations and interest and
                     principal only components of mortgage-backed securities.
                     The Fund may also invest in mortgage dollar roll
                     transactions, Yankee obligations, illiquid securities,
                     shares of other investment companies, obligations of
                     supranational agencies, warrants, when-issued and delayed-
                     delivery securities and zero coupon obligations. The Fund
                     may also borrow money and lend its securities to qualified
                     borrowers.
    
 
   
                           The Core Fixed Income Fund invests in a portfolio
                     with a dollar-weighted average duration that will, under
                     normal market conditions, stay within plus or minus 20% of
                     what the Money Managers believe to be the average duration
                     of the domestic bond market as a whole. The Money Managers
                     base their analysis of the average duration of the domestic
    
 
                                                                              18
<PAGE>
                     bond market on bond market indices which they believe to be
                     representative. The Money Managers currently use the Lehman
                     Aggregate Bond Index for this purpose.
 
HIGH YIELD BOND FUND
   
                     The investment objective of the High Yield Bond Fund is to
                     maximize total return.
    
 
   
                           Under normal market conditions, the Fund will invest
                     at least 65% of its total assets in fixed income securities
                     that are below investment grade, i.e., rated below the top
                     four rating categories by a NRSRO at the time of purchase,
                     or, if not rated, determined to be of comparable quality by
                     the Fund's Money Manager. Below investment grade securities
                     are commonly referred to as "junk bonds," and generally
                     entail increased credit and market risk. See "Lower Rated
                     Securities" in "General Investment Policies and Risk
                     Factors." The achievement of the Fund's investment
                     objective may be more dependent on the Money Manager's own
                     credit analysis than would be the case if the Fund invested
                     in higher rated securities. There is no bottom limit on the
                     ratings of high yield securities that may be purchased and
                     held by the Fund. These securities may have predominantly
                     speculative characteristics or may be in default. Any
                     remaining assets may be invested in equity, investment
                     grade fixed income and money market securities that the
                     Money Manager believes are appropriate in light of the
                     Fund's objective.
    
 
   
                           The Fund may acquire all types of fixed income
                     securities issued by domestic and foreign private and
                     governmental issuers, including mortgage-backed and
                     asset-backed securities, and variable and floating rate
                     securities. The Fund may also invest in Yankee obligations,
                     illiquid securities, shares of other investment companies,
                     warrants, when-issued and delayed-delivery securities, zero
                     coupon obligations, pay-in-kind and deferred payment
                     securities. The Fund may also borrow money, enter into
                     forward foreign currency contracts, and lend its securities
                     to qualified buyers. The Fund's Money Manager may vary the
                     average maturity of the securities in the Fund without
                     limit, and there is no restriction on the maturity of any
                     individual security.
    
 
   
                           The Fund's Money Manager will consider ratings, but
                     it will perform its own analyses and will not rely
                     principally on ratings. The Fund's Money Manager will
                     consider, among other things, the price of the security and
                     the financial history and condition, the prospects and the
                     management of an issuer in selecting securities for the
                     Fund.
    
 
INTERNATIONAL FIXED INCOME FUND
   
                     The International Fixed Income Fund seeks to provide
                     capital appreciation and current income.
    
 
   
                           Under normal market conditions, the Fund will invest
                     in at least 65% of its total assets in investment grade
                     fixed income securities of issuers located in at least
                     three countries other than the United States.
    
 
   
                           The International Fixed Income Fund may invest its
                     remaining assets in obligations issued or guaranteed as to
                     principal and interest by the United States Government, its
                     agencies or instrumentalities ("U.S. Government
                     securities") and preferred stocks of U.S. and foreign
                     issuers. The Fund also may engage in short selling against
                     the box. The Fund may also invest in securities of
                     companies located in and governments of emerging market
    
 
                                                                              19
<PAGE>
   
                     countries, as defined below. Investments in emerging
                     markets countries will not exceed 5% of the Fund's total
                     assets at the time of purchase. Such investments entail
                     different risks than investments in securities of companies
                     and governments of more developed, stable nations.
    
 
   
                           The Fund may acquire all types of fixed income
                     securities issued by foreign private and governmental
                     issuers, including mortgage-backed and asset-backed
                     securities, and variable and floating rate securities. The
                     Fund may invest in traditional fixed income securities such
                     as bonds and debentures, and in structured securities that
                     derive interest and principal payments from specified
                     assets or indices. All such investments will be in
                     investment grade securities denominated in various
                     currencies, including the European Currency Unit. The Fund
                     may also invest in illiquid securities, shares of other
                     investment companies, obligations of supranational
                     entities, warrants, when-issued and delayed-delivery
                     securities and zero coupon obligations. The Fund may also
                     borrow money, enter into forward foreign currency
                     transactions and swap contracts and lend its securities to
                     qualified buyers.
    
 
   
                           There are no restrictions on the average maturity of
                     the Fund or the maturity of any single instrument.
                     Maturities may vary widely depending on the Fund's Money
                     Managers' assessment of interest rate trends and other
                     economic and market factors.
    
 
                           The Fund is a non-diversified fund. Investment in a
                     non-diversified company may entail greater risk than
                     investment in a diversified company. The Fund's ability to
                     focus its investments on a fewer number of issuers means
                     that economic, political or regulatory developments
                     affecting the Fund's investment securities could have a
                     greater impact on the total value of the Fund than would be
                     the case if the Fund were diversified among more issuers.
                     The Fund intends to comply with the diversification
                     requirements of Subchapter M of the Internal Revenue Code
                     of 1986, as amended (the "Code"). See "Taxes" for
                     additional information.
 
   
                     The Emerging Markets Equity Fund seeks to provide capital
                     appreciation.
    
 
   
                           Under normal market conditions, the Fund will invest
                     at least 65% of its total assets in the equity securities
                     of emerging market issuers. The Fund defines an emerging
                     market country as any country the economy and market of
                     which the World Bank or the United Nations considers to be
                     emerging or developing. The Fund's Money Manager considers
                     emerging market issuers to include companies the securities
                     of which are principally traded in the capital markets of
                     emerging market countries; that derive at least 50% of
                     their total revenue from either goods produced or services
                     rendered in emerging market countries, regardless of where
                     the securities of such companies are principally traded; or
                     that are organized under the laws of and have a principal
                     office in an emerging market country. Under normal market
                     conditions, the Fund maintains investments in at least six
                     emerging market countries and does not invest more than 35%
                     of its total assets in any one country.

EMERGING MARKETS EQUITY FUND
 
   
                           The Fund may invest any remaining assets in
                     investment grade fixed income securities, including
                     variable and floating rate securities, of emerging market
                     governments and companies, and may invest up to 5% of its
                     total assets in securities that are rated below investment
                     grade. Certain securities issued by governments of emerging
                     market countries are or may be eligible for conversion into
                     investments in emerging market companies under debt
                     conversion programs sponsored by such governments. Bonds
                     rated below investment grade are often referred to as "junk
                     bonds." Such securities involve greater risk of default or
                     price volatility than investment grade securities. See
                     "Lower Rated Securities" in "General Investment Policies
                     and Risk Factors."
    
 
                           When in the Fund's Money Manager's opinion there is
                     an insufficient supply of suitable securities from emerging
                     market issuers, the Fund may invest up to 20% of its total
                     assets in the equity securities of non-emerging market
                     companies contained in the Morgan Stanley Capital
                     International Europe, Australia and Far East Index (the
                     "EAFE Index"). These companies typically have larger
                     average market capitalizations than the emerging market
                     companies in which the Fund generally invests.
 
   
                           Securities of non-U.S. issuers purchased by the Fund
                     may be purchased on exchanges in foreign markets, on U.S.
                     registered exchanges or the domestic or foreign
                     over-the-counter markets, and may be purchased in initial
                     public offerings. The Fund may also purchase illiquid
                     securities, including "special situation" securities,
                     shares of other investment companies, obligations of
                     supranational entities, when-issued and delayed-delivery
                     securities and zero coupon obligations. The Fund may also
                     borrow money, enter into forward foreign currency
                     transactions and swap contracts and lend its securities to
                     qualified buyers.
    
 
INTERNATIONAL EQUITY FUND
   
                     The International Equity Fund seeks to provide capital
                     appreciation.
    
 
   
                           Under normal market conditions, the Fund will invest
                     at least 65% of its total assets in the equity securities
                     of non-U.S. issuers located in at least three different
                     countries. Any remaining assets will be invested in U.S. or
                     non-U.S. cash reserves and money market instruments, as
                     well as variable and floating rate securities. The Fund may
                     also purchase illiquid securities, shares of other
                     investment companies, obligations of supranational
                     entities, when-issued and delayed-delivery securities and
                     zero coupon obligations. The Fund may also borrow money,
                     enter into forward foreign currency and swap contracts and
                     lend its securities to qualified buyers.
    
 
   
                           Securities of non-U.S. issuers purchased by the Fund
                     may be purchased on exchanges in foreign markets, on U.S.
                     registered exchanges or the domestic or foreign
                     over-the-counter markets.
    
 
   
                           There can be no assurance that the Funds will achieve
                     their respective investment objectives.

GENERAL INVESTMENT
POLICIES AND RISK
FACTORS
    
    ____________________________________________________________________________
 
   
EQUITY SECURITIES
    
   
                     Equity securities represent ownership interests in a
                     company or corporation and include common stock, preferred
                     stock and warrants and other rights to acquire such
                     instruments and convertible securities. Equity securities
                     also include structured securities whose risk and return
                     characteristics are similar to those of traditional equity
                     securities. Changes in the value of portfolio securities
                     will not necessarily affect cash income derived from these
                     securities, but will affect a Fund's net asset value.
    
 
   
FIXED INCOME SECURITIES
    
   
                     Fixed income securities consist primarily of debt
                     obligations issued by governments, corporations,
                     municipalities and other borrowers, but may also include
                     structured securities that provide for participation
                     interests in debt obligations. The market value of fixed
                     income investments will generally change in response to
                     interest rate changes and other factors. During periods of
                     falling interest rates, the values of outstanding fixed
                     income securities generally rise. Conversely, during
                     periods of rising interest rates, the values of such
                     securities generally decline. Moreover, while securities
                     with longer maturities tend to produce higher yields, the
                     prices of longer maturity securities are also subject to
                     greater market fluctuations as a result of changes in
                     interest rates. Changes by recognized agencies in the
                     rating of any fixed income security and in the ability of
                     an issuer to make payments of interest and principal also
                     affect the value of these investments. Changes in the value
                     of these securities will not affect cash income derived
                     from these securities, but will affect a Fund's net asset
                     value.
    
 
   
                           Fixed income securities are considered investment
                     grade if they are rated in one of the four highest rating
                     categories by a nationally recognized statistical rating
                     organization ("NRSRO"), or, if not rated, are determined to
                     be of comparable quality by the Fund's Money Managers. The
                     "Appendix" to this Prospectus sets forth a description of
                     the bond rating categories of several NRSROs. Ratings of
                     each NRSRO represents its opinion of the safety of
                     principal and interest payments (and not the market risk)
                     of bonds and other fixed income securities it undertakes to
                     rate at the time of issuance. Ratings are not absolute
                     standards of quality and may not reflect changes in an
                     issuer's creditworthiness.
    
 
   
                           Fixed income securities rated BBB or Baa lack
                     outstanding investment characteristics, and have
                     speculative characteristics as well. Fixed income
                     securities rated below investment grade are often referred
                     to as "junk bonds." Such securities involve greater risk of
                     default or price declines than investment grade securities.
                     In the event a security owned by a Fund is downgraded, the
                     adviser will review the situation and take appropriate
                     action with regard to the security.
    
 
   
FOREIGN CURRENCY TRANSACTIONS
    
   
                     The Funds may enter into forward foreign currency contracts
                     to manage its foreign currency exposure and as a hedge
                     against possible variations in foreign exchange rates.
    
 
                                                                              22
<PAGE>
   
                     The Funds may enter into forward foreign currency contracts
                     to hedge a specific security transaction or to hedge a
                     portfolio position. These contracts may be bought or sold
                     to protect the Funds, to some degree, against possible
                     losses resulting from an adverse change in the relationship
                     between foreign currencies and the U.S. dollar. The Funds
                     also may invest in foreign currency futures and in options
                     on currencies.
    
   
LOWER RATED SECURITIES
    
                     The High Yield Bond and Emerging Markets Equity Funds may
                     invest in lower rated securities. Fixed income securities
                     are subject to the risk of an issuer's ability to meet
                     principal and interest payments on the obligation (credit
                     risk), and may also be subject to price volatility due to
                     such factors as interest rate sensitivity, market
                     perception of the creditworthiness of the issuer and
                     general market liquidity (market risk). Lower rated or
                     unrated (i.e., high yield) securities are more likely to
                     react to developments affecting market and credit risk than
                     are more highly rated securities, which primarily react to
                     movements in the general level of interest rates. The
                     market values of fixed income securities tend to vary
                     inversely with the level of interest rates. Yields and
                     market values of high yield securities will fluctuate over
                     time, reflecting not only changing interest rates but the
                     market's perception of credit quality and the outlook for
                     economic growth. When economic conditions appear to be
                     deteriorating, medium to lower rated securities may decline
                     in value due to heightened concern over credit quality,
                     regardless of prevailing interest rates. Investors should
                     carefully consider the relative risks of investing in high
                     yield securities and understand that such securities
                     generally are not meant for short-term investing.
 
                           The high yield market is relatively new and its
                     growth paralleled a long period of economic expansion and
                     an increase in merger, acquisition and leveraged buyout
                     activity. Adverse economic developments can disrupt the
                     market for high yield securities, and severely affect the
                     ability of issuers, especially highly leveraged issuers, to
                     service their debt obligations or to repay their
                     obligations upon maturity which may lead to a higher
                     incidence of default on such securities. In addition, the
                     secondary market for high yield securities, which is
                     concentrated in relatively few market makers, may not be as
                     liquid as the secondary market for more highly rated
                     securities. As a result, a Fund's Money Managers could find
                     it more difficult to sell these securities or may be able
                     to sell the securities only at prices lower than if such
                     securities were widely traded. Furthermore, a Fund may
                     experience difficulty in valuing certain securities at
                     certain times. Prices realized upon the sale of such lower
                     rated or unrated securities, under these circumstances, may
                     be less than the prices used in calculating such Fund's net
                     asset value.
 
                           Prices for high yield securities may be affected by
                     legislative and regulatory developments. These laws could
                     adversely affect a Fund's net asset value and investment
                     practices, the secondary market for high yield securities,
                     the financial condition of issuers
 
                                                                              23
<PAGE>
                     of these securities and the value of outstanding high yield
                     securities. For example, federal legislation requiring the
                     divestiture by federally insured savings and loan
                     associations of their investments in high yield bonds and
                     limiting the deductibility of interest by certain corporate
                     issuers of high yield bonds adversely affected the market
                     in recent years.
 
   
                           Lower rated or unrated fixed income obligations also
                     present risks based on payment expectations. If an issuer
                     calls the obligations for redemption, a Fund may have to
                     replace the security with a lower yielding security,
                     resulting in a decreased return for investors. If a Fund
                     experiences unexpected net redemptions, it may be forced to
                     sell its higher rated securities, resulting in a decline in
                     the overall credit quality of the Fund's investment
                     portfolio and increasing the exposure of the Fund to the
                     risks of high yield securities.
    
 
   
MONEY MARKET
    
SECURITIES
   
                     Each Fund may hold cash reserves and invest in money market
                     instruments (including securities issued or guaranteed by
                     the U.S. Government, its agencies or instrumentalities,
                     repurchase agreements, certificates of deposit and bankers'
                     acceptances issued by banks or savings and loan
                     associations having net assets of at least $500 million as
                     of the end of their most recent fiscal year, high-grade
                     commercial paper and other short-term debt securities)
                     rated at the time of purchase in the top two categories by
                     an NRSRO, or, if not rated, determined by the advisers to
                     be of comparable quality at the time of purchase.
    
OPTIONS AND FUTURES
                     Each Fund may purchase or write options (including options
                     on non-U.S. indices and currencies), futures (including
                     futures on U.S. Treasury obligations and Eurodollar
                     instruments) and options on futures. Risks associated with
                     investing in options and futures may include lack of a
                     liquid secondary market, trading restrictions which may be
                     imposed by an exchange, government regulations which may
                     restrict trading, an imperfect correlation between the
                     prices of securities held by a Fund and the price of an
                     option or future and, in the case of non-U.S. futures and
                     options, the risks of investing in foreign markets
                     generally.
PORTFOLIO TURNOVER RATE
   
                     Each Fund's annual portfolio turnover rate will generally
                     not exceed 150%, except for the Core Fixed Income Fund's
                     portfolio turnover rate, which will generally not exceed
                     300%. Portfolio turnover rates over 100% will result in
                     higher transaction costs and may result in additional taxes
                     for shareholders. See "Taxes."
    
 
   
SECURITIES OF FOREIGN AND EMERGING MARKET ISSUERS
    
   
                     There are certain risks connected with investing in foreign
                     securities. These include risks of adverse political and
                     economic developments (including possible governmental
                     seizure or nationalization of assets), the possible
                     imposition of exchange or currency controls or other
                     governmental restrictions, less uniformity in accounting
                     and reporting requirements, the possibility that there will
                     be less information on such securities and their issuers
                     available to the public, the difficulty of obtaining or
                     enforcing court judgments abroad, restrictions on foreign
                     investments in other jurisdictions, difficulties in
                     effecting repatriation of capital invested abroad and
                     difficulties in transaction settlements and the effect of
                     delay on shareholder equity. Foreign securities may be
                     subject to foreign taxes, and may be less
    
 
                                                                              24

                     marketable than comparable U.S. securities. The value of a
                     Fund's investments denominated in foreign currencies will
                     depend on the relative strengths of those currencies and
                     the U.S. dollar, and a Fund may be affected favorably or
                     unfavorably by changes in the exchange rates or exchange or
                     currency control regulations between foreign currencies and
                     the U.S. dollar. Changes in foreign currency exchange rates
                     also may affect the value of dividends and interest earned,
                     gains and losses realized on the sale of securities and net
                     investment income and gains if any, to be distributed to
                     shareholders by a Fund.
    
 
   
                           A Fund's investments in emerging markets can be
                     considered speculative, and therefore may offer higher
                     potential for gains and losses than investments in
                     developed markets of the world. With respect to any
                     emerging country, there may be a greater potential for
                     nationalization, expropriation or confiscatory taxation,
                     political changes, government regulation, social
                     instability or diplomatic developments (including war)
                     which could affect adversely the economies of such
                     countries or investments in such countries. The economies
                     of developing countries generally are heavily dependent
                     upon international trade and, accordingly, have been and
                     may continue to be adversely affected by trade barriers,
                     exchange or currency controls, managed adjustments in
                     relative currency values and other protectionist measures
                     imposed or negotiated by the countries with which they
                     trade.
    
 
   
                           In addition to the risks of investing in emerging
                     market country debt securities, a Fund's investment in
                     government, government-related and restructured debt
                     instruments are subject to special risks, including the
                     inability or unwillingness to repay principal and interest,
                     requests to reschedule or restructure outstanding debt, and
                     requests to extend additional loan amounts. A Fund may have
                     limited recourse in the event of default on such debt
                     instruments.
    
 
   
TEMPORARY DEFENSIVE INVESTMENTS
    
   
                     For temporary defensive purposes, when the Money Managers
                     determine that market conditions warrant, the Funds may
                     invest up to 100% of their assets in U.S. dollar-
                     denominated fixed income securities or debt obligations and
                     in domestic and foreign money market instruments. In
                     addition, the Funds may invest in the foregoing instruments
                     and hold cash for liquidity purposes.

                     permitted investments, see "Description of Permitted
                     Investments and Risk Factors" in this Prospectus and
                     "Description of Permitted Investments" in the Statement of
                     Additional Information. For a description of the above

INVESTMENT LIMITATIONS
        ________________________________________________________________________
 
                     The investment objectives and certain of the investment
                     limitations are fundamental policies of the Funds.
                     Fundamental policies cannot be changed with respect to the
                     Trust or a Fund without the consent of the holders of a
                     majority of the Trust's or that Fund's outstanding shares.
 
                                                                              25
<PAGE>
                     NO FUND MAY:
 
                     1. With respect to 75% of its total assets, (i) purchase
                       securities of any issuer (except securities issued or
                       guaranteed by the United States Government, its agencies
                       or instrumentalities) if, as a result, more than 5% of
                       its total assets would be invested in the securities of
                       such issuer; or (ii) acquire more than 10% of the
                       outstanding voting securities of any one issuer. This
                       restriction does not apply to the International Fixed
                       Income Fund.
 
                     2. Purchase any securities which would cause more than 25%
                       of its total assets 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 securities
                       issued or guaranteed by the United States Government, its
                       agencies or instrumentalities.
 
                     For purposes of the industry concentration limitation,
                     specified in paragraph 2 above, (i) utility companies will
                     be divided according to their services, for example, gas,
                     gas transmission, electric and telephone will each be
                     considered a separate industry; (ii) financial service
                     companies will be classified according to end users of
                     their services, for example, automobile finance, bank
                     finance and diversified finance will each be considered a
                     separate industry; (iii) supranational agencies will be
                     deemed to be issuers conducting their principal business
                     activities in the same industry; and (iv) governmental
                     issuers within a particular country will be deemed to be
                     conducting their principal business activities in the same
                     industry.
 
                           The foregoing percentage limitations will apply at
                     the time of the purchase of a security. Additional
                     fundamental and non-fundamental investment limitations are
                     set forth in the Statement of Additional Information.
 
PURCHASE AND
REDEMPTION OF SHARES
    ____________________________________________________________________________
 
   
                     Shares of each Fund may be purchased or redeemed on days on
                     which the New York Stock Exchange is open for business
                     (each, a "Business Day").
    
 
   
                           Shareholders who desire to purchase shares for cash
                     must place their orders with the Transfer Agent (or its
                     authorized agent) prior to 4:00 p.m. Eastern time on any
                     Business Day for the order to be accepted on that Business
                     Day. Cash investments must be transmitted or delivered in
                     federal funds to the wire agent on the next Business Day
                     following the 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 its shareholders to accept such purchase order.
    
 
                           Purchases will be made in full and fractional shares
                     of a Fund calculated to three decimal places. The Trust
                     will send shareholders a statement of shares owned after
                     each
 
                                                                              26
<PAGE>
                     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 Fund is determined by dividing the total market value
                     of a Fund's investment and other assets, less any
                     liabilities, by the total number of outstanding shares of
                     that Fund. Net asset value per share is determined daily at
                     the close of business of the New York Stock Exchange
                     (currently 4:00 p.m. Eastern time) on each Business Day.
 
   
                           Information about the market value of each portfolio
                     security may be obtained by SEI Management from an
                     independent pricing service. The pricing service relies
                     primarily on prices of actual market transactions as well
                     as trader quotations. However, the pricing service may use
                     a matrix system to determine valuations of equity and fixed
                     income securities. This system considers such factors as
                     security prices, yields, maturities, call features, ratings
                     and developments relating to specific securities in
                     arriving at valuations. The procedures used by the pricing
                     service and its valuations are reviewed by the officers of
                     the Trust under the general supervision of the Trustees.
                     Securities that have maturities of 60 days or less at the
                     time of purchase will be valued using the amortized cost
                     method (described in the Statement of Additional
                     Information).
    
 
   
                           Shares of a Fund may be purchased in exchange for
                     securities included in the Fund subject to SEI Management's
                     determination that the securities are acceptable.
                     Securities accepted in an exchange will be valued at the
                     market value. All accrued interest and subscription of
                     other rights which are reflected in the market price of
                     accepted securities at the time of valuation become the
                     property of the Trust and must be delivered by the
                     Shareholder to the Trust upon receipt from the issuer.
    
 
   
                           SEI Management will not accept securities for a Fund
                     unless (1) such securities are appropriate for the Fund at
                     the time of the exchange; (2) such securities are acquired
                     for investment and not for resale; (3) the Shareholder
                     represents and agrees that all securities offered to the
                     Trust for the Fund are not subject to any restrictions upon
                     their sale by the Fund under the Securities Act of 1933, or
                     otherwise; (4) such securities are traded on the American
                     Stock Exchange, the New York Stock Exchange or on NASDAQ in
                     an unrelated transaction with a quoted sales price on the
                     same day the exchange valuation is made or, if not listed
                     on such exchanges or on NASDAQ, have prices available from
                     an independent pricing service approved by the Trust's
                     Board of Trustees; and (5) the securities may be acquired
                     under the investment restrictions applicable to the Fund.
    
 
   
                           Shareholders who desire to redeem shares of a Fund
                     must place their redemption orders with the Transfer Agent
                     (or its authorized agent) prior to 4:00 p.m. Eastern time
                     on any Business Day. The redemption price is the net asset
                     value per share of the Fund next determined after receipt
                     by the Transfer Agent of the redemption order. Payment on
                     redemption will be made as promptly as possible and, in any
                     event, within seven days after the redemption order is
                     received.
    
 
                           The Trust intends to generally make redemptions in
                     cash. The Trust may, however, make redemptions in whole or
                     in part by a distribution in kind of readily marketable
 
                                                                              27
<PAGE>
                     securities in lieu of cash. Shareholders may incur
                     brokerage costs on the sale of any such securities so
                     received in payment of redemptions.
 
   
                           Purchase and redemption orders may be placed by
                     telephone. Neither the Trust nor the Transfer Agent will be
                     responsible for any loss, liability, cost or expense for
                     acting upon wire instructions or upon telephone
                     instructions that it reasonably believes to be genuine. The
                     Trust and the Transfer Agent will each employ reasonable
                     procedures to confirm that instructions communicated by
                     telephone are genuine, including requiring a form of
                     personal identification prior to acting upon instructions
                     received by telephone and recording telephone instructions.
    
 
                           If market conditions are extraordinarily active, or
                     other extraordinary circumstances exist, and shareholders
                     experience difficulties placing redemption orders by
                     telephone, shareholders may wish to consider placing their
                     order by other means.
PERFORMANCE
          ______________________________________________________________________
 
                     From time to time, a Fund may advertise yield and total
                     return. These figures will be based on historical earnings
                     and are not intended to indicate future performance. No
                     representation can be made concerning actual yield or
                     future returns. The yield of a Fund refers to the
                     annualized income generated by an investment in the Fund
                     over a specified 30-day period. The yield is calculated by
                     assuming that the same amount of income generated by the
                     investment during that period is generated in each 30-day
                     period over one year and is shown as a percentage of the
                     investment.
 
                           The total return of a Fund refers to the average
                     compounded rate of return on a hypothetical investment for
                     designated time periods, assuming that the entire
                     investment is redeemed at the end of each period and
                     assuming the reinvestment of all dividend and capital gain
                     distributions.
 
   
                           A Fund may periodically compare its performance to
                     that of: (i) other mutual funds tracked by mutual fund
                     rating services (such as Lipper Analytical), or by
                     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. A
                     Fund may quote Morningstar, Inc., a service that ranks
                     mutual funds on the basis of risk-adjusted performance. A
                     Fund may use long-term performance of these capital markets
                     to demonstrate general long-term risk versus reward
                     scenarios and could include the value of a hypothetical
                     investment in any of the capital markets. A Fund may also
                     quote financial and business publications and periodicals
                     as they relate to fund management, investment philosophy
                     and investment techniques.
    
 
                           A Fund may quote various measures of volatility and
                     benchmark correlation in advertising and may compare these
                     measures to those of other funds. Measures of volatility
                     attempt to compare historical share price fluctuations or
                     total returns to a benchmark while measures of benchmark
                     correlation indicate how valid a comparative
 
                                                                              28
<PAGE>
                     benchmark might be. Measures of volatility and correlation
                     are calculated using averages of historical data and cannot
                     be calculated precisely.
TAXES
  ______________________________________________________________________________
 
                     The following summary of federal income tax consequences is
                     based on current tax laws and regulations, which may be
                     changed by legislative, judicial or administrative action.
                     No attempt has been made to present a detailed explanation
                     of the federal, state or local tax treatment of the Funds
                     or their shareholders. Accordingly, shareholders are urged
                     to consult their tax advisers regarding specific questions
                     as to federal, state and local taxes. State and local tax
                     consequences of an investment in a Fund may differ from the
                     federal income tax consequences described below. Additional
                     information concerning taxes is set forth in the Statement
                     of Additional Information.
TAX STATUS OF THE FUNDS
                     Each Fund is treated as a separate entity for federal
                     income tax purposes and is not combined with the Trust's
                     other funds. The Funds intend to qualify for the special
                     tax treatment afforded regulated investment companies
                     ("RICs") under Subchapter M of the Code so as to be
                     relieved of federal income tax on net investment company
                     taxable income and net capital gains (the excess of net
                     long-term capital gain over net short-term capital losses)
                     distributed to shareholders.
TAX STATUS OF DISTRIBUTIONS
   
                     Each Fund distributes substantially all of its net
                     investment income (including net short-term capital gains)
                     to shareholders. Dividends from a Fund'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 to
                     shareholders as gain from the sale or exchange of a capital
                     asset held for more than one year regardless of how long
                     the shareholder has held shares. Dividends distributions of
                     the Core Fixed Income Fund, High Yield Bond Fund,
                     International Fixed Income Fund, Emerging Markets Equity
                     Fund and International Equity Fund will not qualify for the
                     corporate dividends-received deduction. The Funds will
                     provide annual reports to shareholders of the federal
                     income tax status of all distributions.
    
 
                           Dividends declared by a Fund 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 Fund and received by the Shareholders on December 31
                     of the year declared if paid by the Fund at any time during
                     the following January.
 
                           Each Fund intends to make sufficient distributions to
                     avoid liability for the federal excise tax applicable to
                     RICs.
 
                           Investment income received by the Funds from sources
                     within foreign countries may be subject to foreign income
                     taxes withheld at the source. To the extent that a Fund is
                     liable for foreign income taxes so withheld, the Fund
                     intends to operate so as to meet the requirements of the
                     Code to pass through to the shareholders credit for foreign
 
                                                                              29
<PAGE>
                     income taxes paid. Although the Funds intend to meet Code
                     requirements to pass through credit for such taxes, there
                     can be no assurance that the Funds will be able to do so.
 
                           Each sale, exchange or redemption of Fund shares is a
                     taxable transaction to the shareholder.
GENERAL INFORMATION
                  ______________________________________________________________
 
TRUSTEES OF THE TRUST
   
                     The management and affairs of the Trust are supervised by
                     the Trustees under the laws of the Commonwealth of
                     Massachusetts. The Trustees have approved contracts under
                     which, as described above, certain companies provide
                     essential management services to the Trust. All
                     consideration received by the Trust for shares of any fund,
                     and all assets of such fund belong to that fund and would
                     be subject to the liabilities related thereto. The Trust
                     pays its expenses, including the fees of its service
                     providers, audit and legal expenses, expenses of preparing
                     prospectuses, proxy solicitation materials and reports to
                     shareholders, costs of custodial services and registering
                     the shares under federal and state securities laws,
                     pricing, insurance expenses, litigation and other
                     extraordinary expenses, brokerage costs, interest charges,
                     taxes and organizational expenses.
    
VOTING RIGHTS
                     Each share held entitles the shareholder of record to one
                     vote. The shareholders of each Fund will vote separately on
                     matters pertaining solely to that Fund, such as any
                     distribution plan. As a Massachusetts business trust, the
                     Trust is not required to hold annual meetings of
                     shareholders, but approval will be sought for certain
                     changes in the operation of the Trust and for the election
                     of Trustees under certain circumstances. In addition, a
                     Trustee may be removed by the remaining Trustees or by
                     shareholders at a special meeting called upon written
                     request of shareholders owning at least 10% of the
                     outstanding shares of the Trust. In the event that such a
                     meeting is requested, the Trust will provide appropriate
                     assistance and information to the shareholders requesting
                     the meeting.
 
   
                           As of September 1, 1997, Bank of America NT and SA
                     owned a controlling interest (as defined by the Investment
                     Company Act of 1940) in the Trust's International Equity,
                     Core Fixed Income, Large Cap and Small Cap Funds.
    
REPORTING
                     The Trust issues an unaudited financial report
                     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 SEI Fund
                     Management, Oaks, Pennsylvania 19456.
    
DIVIDENDS
                     Substantially all of the net investment income (exclusive
                     of capital gains) of each Fund is periodically declared and
                     paid as a dividend. Dividends currently are paid
                     periodically for the International Fixed Income, Emerging
                     Markets Equity and International Equity Funds, monthly for
                     the Core Fixed Income and High Yield Bond Funds and
                     quarterly for the Small
 
                                                                              30
<PAGE>
                     Cap and Large Cap Funds. Currently, net capital gains for
                     all the Funds (the excess of net long-term capital gain
                     over net short-term capital loss) realized, if any, will be
                     distributed at least annually.
 
   
                           Shareholders automatically receive all income
                     dividends and capital gains 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 SEI Management at
                     least 15 days prior to the distribution.
    
 
                           Dividends and capital gains of each Fund are paid 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 capital
                     gains distributions, a shareholder will pay the full price
                     for the share and receive some portion of the price back as
                     a taxable dividend or distribution.
MASTER/FEEDER OPTION
   
                     The Trust may in the future seek to achieve any Fund's
                     investment objective by investing all of that Fund's assets
                     in another investment company having the same investment
                     objective and substantially the same investment policies
                     and restrictions as those applicable to that Fund. It is
                     expected that any such investment company would be managed
                     by SIMC in substantially the same manner as the existing
                     Fund. The initial shareholder(s) of each Fund voted to vest
                     such authority in the sole discretion of the Trustees and
                     such investment may be made without further approval of the
                     shareholders of the Funds. However, shareholders of the
                     Funds will be given at least 30 days' prior notice of any
                     such investment. Such investment would be made only if the
                     Trustees determine it to be in the best interests of a Fund
                     and its shareholders. In making that determination the
                     Trustees will consider, among other things, the benefits to
                     shareholders and/or the opportunity to reduce costs and
                     achieve operational efficiencies. Although the Funds
                     believe that the Trustees will not approve an arrangement
                     that is likely to result in higher costs, no assurance is
                     given that costs will be materially reduced if this option
                     is implemented.

DESCRIPTION OF
PERMITTED INVESTMENTS
AND
RISK FACTORS
          ______________________________________________________________________
 
                     The following is a description of the permitted investment
                     practices for the Funds, and the associated risk factors:
AMERICAN DEPOSITARY RECEIPTS ("ADRS"), EUROPEAN DEPOSITARY RECEIPTS ("EDRS") AND
GLOBAL DEPOSITARY RECEIPTS ("GDRS")
   
                     ADRs are securities, typically issued by a U.S. financial
                     institution (a "depositary"), that evidence ownership
                     interests in a security or a pool of securities issued by a
                     foreign issuer and deposited with the depositary. ADRs
                     include American Depositary Shares and New York Shares.
                     EDRs, which are sometimes referred to as Continental
                     Depositary Receipts ("CDRs"), are securities, typically
                     issued by a non-U.S. financial institution, that evidence
                     ownership interests in a security or a pool of securities
                     issued by either a U.S. or foreign issuer. GDRs are issued
                     globally and evidence a similar ownership arrangement.
                     Generally, ADRs are designed for trading in the U.S.
                     securities market, EDRs are designed for trading in
                     European securities market and GDRs are designed for
                     trading in non-U.S. securities markets. ADRs, EDRs, CDRs
                     and GDRs may be available for investment through
                     "sponsored" or "unsponsored" facilities. A sponsored
                     facility is established jointly by the issuer of the
                     security underlying the receipt and a depositary, whereas
                     an unsponsored facility may be established by a depositary
                     without participation by the issuer of the receipt's
                     underlying security.
    
ASSET-BACKED SECURITIES
                     Asset-backed securities are secured by non-mortgage assets
                     such as company receivables, truck and auto loans, leases
                     and credit card receivables. Such securities are generally
                     issued as pass-through certificates, which represent
                     undivided fractional ownership interests in the underlying
                     pools of assets. Such securities also may be debt
                     instruments, which are also known as collateralized
                     obligations and are generally issued as the debt of a
                     special purpose entity, such as a trust, organized solely
                     for the purpose of owning such assets and issuing such
                     debt. A Fund may invest in other asset-backed securities
                     that may be created in the future if the Money Managers
                     determine that they are suitable.
CONVERTIBLE SECURITIES
                     Convertible securities are corporate securities that are
                     exchangeable for a set number of another security at a
                     prestated price. Convertible securities typically have
                     characteristics similar to both fixed income and equity
                     securities. Because of the conversion feature, the market
                     value of a convertible security tends to move with the
                     market value of the underlying stock. The value of a
                     convertible security is also affected by prevailing
                     interest rates, the credit quality of the issuer, and any
                     call provisions.
DEMAND INSTRUMENTS
                     Certain instruments may entail a demand feature which
                     permits the holder to demand payment of the principal
                     amount of the instrument. Demand instruments include
                     variable rate demand notes.

DERIVATIVES
   
                     Derivatives are investments that derive their value from
                     other securities, assets or indices. The following may be
                     considered derivative securities: futures, options on
                     futures, options (e.g., puts and calls), swap agreements,
                     mortgage-backed securities (e.g., CMOs, REMICs, IOs and
                     POs), when-issued securities and forward commitments,
                     floating and variable rate securities, convertible
                     securities, "stripped" U.S. Treasury securities (e.g.,
                     receipts and STRIPs), privately issued stripped securities
                     (e.g., TIGRs, TRs and CATS). See elsewhere in this
                     "Description of Permitted Investments and Risk Factors" for
                     discussions of certain of these instruments, and see
                     "Investment Objectives and Policies" for more information
                     about any investment policies and limitations applicable to
                     their use.
    
FORWARD FOREIGN CURRENCY CONTRACTS
   
                     A forward contract involves an obligation to purchase or
                     sell a specific currency amount at a future date, agreed
                     upon by the parties, at a price set at the time of the
                     contract. A Fund may enter into a contract to sell, for a
                     fixed amount of U.S. dollars or other appropriate currency,
                     the amount of foreign currency approximating the value of
                     some or all of the Fund's securities denominated in such
                     foreign currency.
    
 
   
                           At the maturity of a forward contract, the Fund may
                     either sell a fund security and make delivery of the
                     foreign currency, or it may retain the security and
                     terminate its contractual obligation to deliver the foreign
                     currency by purchasing an "offsetting" contract with the
                     same currency trader, obligating it to purchase, on the
                     same maturity date, the same amount of the foreign
                     currency. The Fund may realize a gain or loss from currency
                     transactions.
    
   
FUTURES AND OPTIONS ON FUTURES
    
   
                     Futures contracts provide for the future sale by one party
                     and purchase by another party of a specified amount of a
                     specific security at a specified future time and at a
                     specified price. An option on a futures contract gives the
                     purchaser the right, in exchange for a premium, to assume a
                     position in a futures contract at a specified exercise
                     price during the term of the option. A Fund may use futures
                     contracts and related options for bona fide hedging
                     purposes, to offset changes in the value of securities held
                     or expected to be acquired or be disposed of, to minimize
                     fluctuations in foreign currencies, or to gain exposure to
                     a particular market or instrument. A Fund will minimize the
                     risk that it will be unable to close out a futures contract
                     by only entering into futures contracts which are traded on
                     national futures exchanges.
    
 
   
                           An index futures contract is a bilateral agreement
                     pursuant to which two parties agree to take or make
                     delivery of an amount of cash equal to a specified dollar
                     amount times the difference between the index value at the
                     close of trading of the contract and the price at which the
                     futures contract is originally struck. No physical delivery
                     of the securities comprising the Index is made; generally
                     contracts are closed out prior to the expiration date of
                     the contract.
    
 
   
                           In order to avoid leveraging and related risks, when
                     a Fund invests in futures contracts, it will cover its
                     position by depositing an amount of cash or liquid
                     securities, equal to the market value of the futures
                     positions held, less margin deposits, in a segregated
                     account and that amount will be marked to market on a daily
                     basis.
    
 
                                                                              33
<PAGE>
   
                           A Fund may enter into futures contracts and options
                     on futures contracts traded on an exchange regulated by the
                     Commodities Futures Trading Commission ("CFTC"), as long
                     as, to the extent that such transactions are not for "bona
                     fide hedging purposes," the aggregate initial margin and
                     premiums on such positions (excluding the amount by which
                     such options are in the money) do not exceed 5% of a Fund's
                     net assets.
    
 
   
                           There are risks associated with these activities,
                     including the following: (1) the success of a hedging
                     strategy may depend on an ability to predict movements in
                     the prices of individual securities, fluctuations in
                     markets and movements in interest rates; (2) there may be
                     an imperfect or no correlation between the changes in
                     market value of the securities held by the Fund and the
                     prices of futures and options on futures; (3) there may not
                     be a liquid secondary market for a futures contract or
                     option; (4) trading restrictions or limitations may be
                     imposed by an exchange; and (5) government regulations may
                     restrict trading in futures contracts and futures options.
    
ILLIQUID SECURITIES
   
                     Illiquid securities are securities that cannot be disposed
                     of within seven business days at approximately the price at
                     which they are being carried on the Fund's books. Illiquid
                     securities include demand instruments with a demand notice
                     period exceeding seven days, securities for which there is
                     no active secondary market, and repurchase agreements with
                     durations over 7 days in length.
    
 
   
                           The Emerging Markets Equity Fund's Money Managers
                     believe that carefully selected investments in joint
                     ventures, cooperatives, partnerships, private placements,
                     unlisted securities and other similar situations
                     (collectively, "special situations") could enhance its
                     capital appreciation potential. Investments in special
                     situations may be illiquid, as determined by the Emerging
                     Markets Equity Fund's Money Managers based on criteria
                     approved by the Board of Trustees. To the extent these
                     investments are deemed illiquid, the Emerging Markets
                     Equity Fund's investment in them will be consistent with
                     its 15% restriction on investment in illiquid securities.
    
INVESTMENT COMPANIES
   
                     Because of restrictions on direct investment by U.S.
                     entities in certain countries, investment in other
                     investment companies may be the most practical or only
                     manner in which an international and global fund can invest
                     in the securities markets of those countries. A Fund does
                     not intend to invest in other investment companies unless,
                     in the judgment of its Money Managers, the potential
                     benefits of such investments exceed the associated costs
                     (which includes any investment advisory fees charged by the
                     investment companies) relative to the benefits and costs
                     associated with direct investments in the underlying
                     securities.
    
 
   
                           Investments in closed-end investment companies may
                     involve the payment of substantial premiums above the net
                     asset value of such issuers' fund securities, and are
                     subject to limitations under the 1940 Act. A Fund may incur
                     tax liability to the extent it invests in the stock of a
                     foreign issuer that constitutes a "passive foreign
                     investment company."
    
 
                                                                              34

JUNK BONDS
    
   
                     Bonds rated below investment grade are often referred to as
                     "junk bonds." Such securities involve greater risk of
                     default or price declines than investment grade securities
                     due to changes in the issuer's creditworthiness and the
                     outlook for economic growth. The market for these
                     securities may be less active, causing market price
                     volatility and limited liquidity in the secondary market.
                     This may limit a Fund's ability to sell such securities at
                     their market value. In addition, the market for these
                     securities may also be adversely affected by legislative
                     and regulatory developments. Credit quality in the junk
                     bond market can change suddenly and unexpectedly, and even
                     recently issued credit ratings may not fully reflect the
                     actual risks imposed by a particular security.
    
MONEY MARKET SECURITIES
   
                     Money market securities are high-quality dollar and
                     nondollar-denominated, short-term debt instruments. They
                     consist of: (i) bankers' acceptances, certificates of
                     deposits, notes and time deposits of highly-rated U.S. and
                     foreign banks; (ii) U.S. Treasury obligations and
                     obligations issued or guaranteed by the agencies and
                     instrumentalities of the U.S. Government; (iii)
                     high-quality commercial paper issued by U.S. and foreign
                     corporations; (iv) debt obligations with a maturity of one
                     year or less issued by corporations and governments that
                     issue high-quality commercial paper or similar securities;
                     (v) repurchase agreements involving any of the foregoing
                     obligations entered into with highly-rated banks and
                     broker-dealers; and (vi) foreign government obligations.
    
MORTGAGE-BACKED SECURITIES
                     Mortgage-backed securities are instruments that entitle the
                     holder to a share of all interest and principal payments
                     from mortgages underlying the security. The mortgages
                     backing these securities include conventional fifteen and
                     thirty-year fixed-rate mortgages, graduated payment
                     mortgages, adjustable rate mortgages and balloon mortgages.
                     During periods of declining interest rates, prepayment of
                     mortgages underlying mortgage-backed securities can be
                     expected to accelerate. Prepayment of mortgages which
                     underlie securities purchased at a premium often results in
                     capital losses, while prepayment of mortgages purchased at
                     a discount often results in capital gains. Because of these
                     unpredictable prepayment characteristics, it is often not
                     possible to predict accurately the average life or realized
                     yield of a particular issue.
 
   
                           GOVERNMENT PASS-THROUGH SECURITIES:  These are
                     securities that are issued or guaranteed by a U.S.
                     Government agency representing an interest in a pool of
                     mortgage loans. The primary issuers or guarantors of these
                     mortgage-backed securities are the Government National
                     Mortgage Association ("GNMA"), Fannie Mae and the Federal
                     Home Loan Mortgage Company ("FHLMC"). Fannie Mae and FHLMC
                     obligations are not backed by the full faith and credit of
                     the U.S. Government as GNMA certificates are, but Fannie
                     Mae and FHLMC securities are supported by the
                     instrumentalities' right to borrow from the U.S. Treasury.
                     GNMA, Fannie Mae and FHLMC each guarantee timely
                     distributions of interest to certificate holders. GNMA and
                     Fannie Mae also each guarantee timely distributions of
                     scheduled principal.
    
 
   
                           PRIVATE PASS-THROUGH SECURITIES:  These are
                     mortgage-backed securities issued by a non-governmental
                     entity, such as a trust. While they are generally
                     structured with one or
    
 
                                                                              35
<PAGE>
                     more types of credit enhancement, private pass-through
                     securities typically lack a guarantee by an entity having
                     the credit status of a governmental agency or
                     instrumentality.
 
                           COMMERCIAL MORTGAGE-BACKED SECURITIES ("CMBS"):  CMBS
                     are generally multi-class or pass-through securities backed
                     by a mortgage loan or a pool of mortgage loans secured by
                     commercial property, such as industrial and warehouse
                     properties, office buildings, retail space and shopping
                     malls, multifamily properties and cooperative apartments.
                     The commercial mortgage loans that underlie CMBS have
                     certain distinct characteristics. Commercial mortgage loans
                     are generally not amortizing or not fully amortizing. That
                     is, at their maturity date, repayment of the remaining
                     principal balance or "balloon" is due and is repaid through
                     the attainment of an additional loan of sale of the
                     property. Unlike most single family residential mortgages,
                     commercial real estate property loans often contain
                     provisions which substantially reduce the likelihood that
                     such securities will be prepaid. The provisions generally
                     impose significant prepayment penalties on loans and, in
                     some cases there may be prohibitions on principal
                     prepayments for several years following origination.
 
   
                           COLLATERALIZED MORTGAGE OBLIGATIONS ("CMOS"):  CMOs
                     are debt obligations of multiclass pass-through
                     certificates issued by agencies or instrumentalities of the
                     U.S. Government or by private originators or investors in
                     mortgage loans. In a CMO, series of bonds or certificates
                     are usually issued in multiple classes. Principal and
                     interest paid on the underlying mortgage assets may be
                     allocated among the several classes of a series of a CMO in
                     a variety of ways. Each class of a CMO is issued with a
                     specific fixed or floating coupon rate and has a stated
                     maturity or final distribution date.
    
 
   
                           REMICS:  A REMIC is a CMO that qualifies for special
                     tax treatment under the Code and invests in certain
                     mortgages principally secured by interests in real
                     property. Guaranteed REMIC pass-through certificates
                     ("REMIC Certificates") issued by Fannie Mae or FHLMC
                     represent beneficial ownership interests in a REMIC trust
                     consisting principally of mortgage loans or Fannie Mae,
                     FHLMC or GNMA-guaranteed mortgage pass-through
                     certificates.
    
 
   
                           STRIPPED MORTGAGE-BACKED SECURITIES ("SMBS"):  SMBs
                     are usually structured with two classes that receive
                     specified proportions of the monthly interest and principal
                     payments from a pool of mortgage securities. One class may
                     receive all of the interest payments while the other class
                     may receive all of the principal payments. SMBs are
                     extremely sensitive to changes in interest rates because of
                     the impact thereon of prepayment of principal on the
                     underlying mortgage securities. The market for SMBs is not
                     as fully developed as other markets; SMBs therefore may be
                     illiquid.

MORTGAGE DOLLAR ROLLS
                     Mortgage "dollar rolls," or "covered rolls," are
                     transactions in which a Fund sells securities (usually
                     mortgage-backed securities) and simultaneously contracts to
                     repurchase, typically in 30 or 60 days, substantially
                     similar, but not identical, securities on a specified
                     future date. During the roll period, a Fund forgoes
                     principal and interest paid on such securities. A Fund is
                     compensated by the difference between the current sales
                     price and the forward price for the future purchase (often
                     referred to as the "drop") as well as by the interest
                     earned on the cash proceeds of the initial sale. A "covered
                     roll" is a specific type of mortgage dollar roll for which
                     there is an offsetting cash position or cash equivalent
                     securities position that matures on or before the forward
                     settlement date of the mortgage dollar roll transaction. As
                     used herein the term "mortgage dollar roll" refers to
                     mortgage dollar rolls that are not "covered rolls." At the
                     end of the roll commitment period, a Fund may or may not
                     take delivery of the securities it has contracted to
                     purchase.
OBLIGATIONS OF SUPRANATIONAL ENTITIES
                     Supranational entities are entities established through the
                     joint participation of several governments, and include the
                     Asian Development Bank, the Inter-American Development
                     Bank, International Bank for Reconstruction and Development
                     (World Bank), African Development Bank, European Economic
                     Community, European Investment Bank and the Nordic
                     Investment Bank. The governmental members, or
                     "stockholders," usually make initial capital contributions
                     to the supranational entity and, in many cases, are
                     committed to make additional capital contributions if the
                     supranational entity is unable to repay its borrowings.
OPTIONS
                     A Fund may purchase and write put and call options on
                     indices or securities and enter into related closing
                     transactions. A put option on a security gives the
                     purchaser of the option the right to sell, and the writer
                     of the option the obligation to buy, the underlying
                     security at any time during the option period. A call
                     option on a security gives the purchaser of the option the
                     right to buy, and the writer of the option the obligation
                     to sell, the underlying security at any time during the
                     option period. The premium paid to the writer is the
                     consideration for undertaking the obligations under the
                     option contract.
 
                           Options on an index give the holder the right to
                     receive, upon exercise of the option, an amount of cash if
                     the closing level of the underlying index is greater than
                     (or less than, in the case of puts) the exercise price of
                     the option. Alternatively, a Fund may choose to terminate
                     an option position by entering into a closing transaction.
                     All settlements are in cash, and gain or loss depends on
                     price movements in the particular market represented by the
                     index generally, rather than the price movements in
                     individual securities.
 
                           A Fund that may invest in the securities of a foreign
                     issuer may also purchase and write put and call options on
                     foreign currencies to manage its exposure to exchange
                     rates. Call options on foreign currency written by a Fund
                     will be "covered," which means that the Fund will own an
                     equal amount of the underlying foreign currency. With
                     respect to put options on foreign currency written by a
                     Fund, the Fund will establish a segregated
 
                                                                              37
<PAGE>
                     account with its custodian bank consisting of cash or
                     liquid securities in an amount equal to the amount the Fund
                     would be required to pay upon exercise of the put.
 
                           All options written on indices or securities must be
                     covered. When a Fund writes an option or security on an
                     index, it will establish a segregated account containing
                     cash or liquid securities in an amount at least equal to
                     the market value of the option and will maintain the
                     account while the option is open, or will otherwise cover
                     the transaction.
 
                           RISK FACTORS.  Risks associated with options
                     transactions include: (1) the success of a hedging strategy
                     may depend on an ability to predict movements in the prices
                     of individual securities, fluctuations in markets and
                     movements in interest rates; (2) there may be an imperfect
                     correlation between the movement in prices of options and
                     the securities underlying them; (3) there may not be a
                     liquid secondary market for options; and (4) while a Fund
                     will receive a premium when it writes covered call options,
                     it may not participate fully in a rise in the market value
                     of the underlying security.
PRIVATIZATIONS
                     Privatizations are foreign government programs for selling
                     all or part of the interests in government owned or
                     controlled enterprises. The ability of a U.S. entity to
                     participate in privatizations in certain foreign countries
                     may be limited by local law, or the terms on which the Fund
                     may be permitted to participate may be less advantageous
                     than those applicable for local investors. There can be no
                     assurance that foreign governments will continue to sell
                     their interests in companies currently owned or controlled
                     by them or that privatization programs will be successful.
RECEIPTS
                     Receipts 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 fixed income securities.
REITS
                     REITs are trusts that invest primarily in commercial real
                     estate or real estate-related loans. The value of interests
                     in REITs may be affected by the value of the property owned
                     or the quality of the mortgages held by the trust.
REPURCHASE AGREEMENTS
                     Arrangements by which a Fund obtains a security and
                     simultaneously commits to return the security to the seller
                     at an agreed upon price (including principal and interest)
                     on an agreed upon date within a number of days from the
                     date of purchase. Repurchase agreements are considered
                     loans under the 1940 Act.
SECURITIES LENDING
                     In order to generate additional income, a Fund may lend
                     securities that it owns pursuant to agreements requiring
                     that the loan be continuously secured by collateral
                     consisting of cash, securities of the U.S. Government or
                     its agencies equal to at least 100% of the market value of
                     the loaned securities. A Fund continues to receive interest
                     on the loaned securities while simultaneously earning
                     interest on the investment of cash collateral. Collateral
                     is marked to market daily. There may be risks of delay in
                     recovery of the
 
                                                                              38
<PAGE>
                     securities or even loss of rights in the collateral should
                     the borrower of the securities fail financially or become
                     insolvent.
SHORT SALES
                     A Fund may only sell securities short "against the box." A
                     short sale is "against the box" if, at all times during
                     which the short position is open, the Fund owns at least an
                     equal amount of the securities or securities convertible
                     into, or exchangeable without further consideration for,
                     securities of the same issue as the securities that are
                     sold short.
SWAPS, CAPS, FLOORS AND COLLARS
                     Interest rate swaps, mortgage swaps, currency swaps and
                     other types of swap agreements such as caps, floors and
                     collars are designed to permit the purchaser to preserve a
                     return or spread on a particular investment or portion of
                     its portfolio, and to protect against any increase in the
                     price of securities a Fund anticipates purchasing at a
                     later date.
 
                           Swap agreements will tend to shift a Fund's
                     investment exposure from one type of investment to another.
                     Depending on how they are used, swap agreements may
                     increase or decrease the overall volatility of the Fund's
                     investments and their share price or yield.
U.S. GOVERNMENT AGENCY SECURITIES
                     Obligations issued or guaranteed by agencies of the U.S.
                     Government, including, among others, the Federal Farm
                     Credit Bank, the Federal Housing Administration and the
                     Small Business Administration, and obligations issued or
                     guaranteed by instrumentalities of the U.S. Government,
                     including, among others, the FHLMC, the Federal Land Banks
                     and the U.S. Postal Service. Some of these securities are
                     supported by the full faith and credit of the U.S. Treasury
                     (e.g., GNMA securities), others are supported by the right
                     of the issuer to borrow from the Treasury (e.g., Federal
                     Farm Credit Bank securities), while still others are
                     supported only by the credit of the instrumentality (e.g.,
                     Fannie Mae securities).
U.S. TREASURY OBLIGATIONS
                     U.S. Treasury obligations consist of bills, notes and bonds
                     issued by the U.S. Treasury as well as separately traded
                     interest and principal component parts of such obligations
                     that are transferable through the Federal book-entry
                     Principal Securities ("STRIPS").
U.S. TREASURY RECEIPTS
                     U. S. Treasury receipts are interests in separately traded
                     interest and principal component parts of U.S. Treasury
                     obligations that are issued by banks or brokerage firms and
                     are created by depositing U.S. Treasury notes and
                     obligations into a special account at a custodian bank. The
                     custodian holds the interest and principal payments for the
                     benefit of the registered owners of the certificates of
                     receipts. The custodian arranges for the issuance of the
                     certificates or receipts evidencing ownership and maintains
                     the register.
VARIABLE AND FLOATING RATE INSTRUMENTS
                     Certain obligations may carry variable or floating rates of
                     interest, and may involve a conditional or unconditional
                     demand feature. Such instruments bear interest at rates
                     that 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
                     some other reset period, and may have a floor or ceiling on
                     interest rate changes.
WARRANTS
                     Warrants are instruments giving holders the right, but not
                     the obligation, to buy equity or fixed income securities of
                     a company at a given price during a specified period.
 
                                                                              39

WHEN-ISSUED AND DELAYED DELIVERY SECURITIES, INCLUDING TBA MORTGAGE-BACKED
SECURITIES
                     When-issued or delayed delivery basis transactions involve
                     the purchase of an instrument with payment and delivery
                     taking place in the future. Delivery of and payment for
                     these securities may occur a month or more after the date
                     of the purchase commitment. A Fund will maintain a separate
                     account with liquid securities or cash in an amount at
                     least equal to these commitments. The interest rate
                     realized on these securities is fixed as of the purchase
                     date, and no interest accrues to a Fund before settlement.
YANKEE OBLIGATIONS
                     Yankee obligations ("Yankees") are U.S. dollar-denominated
                     instruments of foreign issuers who either register with the
                     SEC or issue under Rule 144A under the Securities Act of
                     1933. These obligations consist of debt securities
                     (including preferred or preference stock of
                     non-governmental issuers), certificates of deposit, fixed
                     time deposits and bankers' acceptances issued by foreign
                     banks, and debt obligations of foreign governments or their
                     subdivisions, agencies and instrumentalities, international
                     agencies and supranational entities. Some securities issued
                     by foreign governments or their subdivisions, agencies and
                     instrumentalities may not be backed by the full faith and
                     credit of the foreign government.
 
                           The Yankee obligations selected for a Fund will
                     adhere to the same quality standards as those utilized for
                     the selection of domestic debt obligations.
ZERO COUPON, PAY-IN-KIND AND DEFERRED PAYMENT SECURITIES
                     Zero coupon securities are securities that are sold at a
                     discount to par value, and securities on which interest
                     payments are not made during the life of the security. Upon
                     maturity, the holder is entitled to receive the par value
                     of the security. While interest payments are not made on
                     such securities, holders of such securities are deemed to
                     have received "phantom income" annually. Because a Fund
                     will distribute its "phantom income" to shareholders, to
                     the extent that shareholders elect to receive dividends in
                     cash rather than reinvesting such dividends in additional
                     shares, the Fund will have fewer assets with which to
                     purchase income producing securities. Pay-in-kind
                     securities pay interest in either cash or additional
                     securities, at the issuer's option, for a specified period.
                     Pay-in-kind bonds, like zero coupon bonds, are designed to
                     give an issuer flexibility in managing cash flow.
                     Pay-in-kind bonds are expected to reflect the market value
                     of the underlying debt plus an amount representing accrued
                     interest since the last payment. Pay-in-kind bonds are
                     usually less volatile than zero coupon bonds, but more
                     volatile than cash pay securities. Pay-in-kind securities
                     are securities that have interest payable by delivery of
                     additional securities. Upon maturity, the holder is
                     entitled to receive the aggregate par value of the
                     securities. Deferred payment securities are securities that
                     remain zero coupon securities until a predetermined date,
                     at which time the stated coupon rate becomes effective and
                     interest becomes payable at regular intervals.
 
                           To avoid any leveraging concerns, the Fund will place
                     U.S. Government or other liquid securities in a segregated
                     account in an amount sufficient to cover its repurchase
                     obligation. Zero coupon, pay-in-kind and deferred payment
                     securities may be subject to greater fluctuation in value
                     and lesser liquidity in the event of adverse market
                     conditions than comparably rated securities paying cash
                     interest at regular interest payment periods.

APPENDIX--DESCRIPTION OF CORPORATE BOND RATINGS ________________________________
 
DESCRIPTION OF MOODY'S LONG-TERM RATINGS
 
Aaa
     Bonds which are rated Aaa are judged to be of the best quality. They carry
     the smallest degree of investment risk and are generally referred to as
     "gilt edged." Interest payments are protected by a large or by 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.
 
Aa
     Bonds which are rated Aa are judged to be of high quality by all standards.
     Together with the Aaa group 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 risk appear somewhat larger than
     the Aaa securities.
 
A
     Bonds which are rated A possess many favorable investment attributes and
     are to be considered as upper-medium grade obligations. Factors giving
     security to principal and interest are considered adequate, but elements
     may be present which suggest a susceptibility to impairment some time in
     the future.
 
Baa
     Bonds which are rated Baa are considered as medium-grade obligations (i.e.,
     they are neither highly protected nor poorly secured). Interest payments
     and principal security appear adequate for the present but certain
     protective elements may be lacking or may be characteristically unreliable
     over any great length of time. Such bonds lack outstanding investment
     characteristics and in fact have speculative characteristics as well.
 
Ba
     Bonds which are rated Ba are judged to have speculative elements; their
     future cannot be considered as well-assured. Often the protection of
     interest and principal payments may be very moderate and thereby not well
     safeguarded during both good and bad times over the future. Uncertainty of
     position characterizes bonds in this class.
 
B
     Bonds which are rated B generally lack characteristics of the desirable
     investment. Assurance of interest and principal payments or of maintenance
     of other terms of the contract over any long period of time may be small.
 
Caa
     Bonds which are rated Caa are of poor standing. Such issues may be in
     default or there may be present elements of danger with respect to
     principal or interest.
 
Ca
     Bonds which are rated Ca represent obligations which are speculative in a
     high degree. Such issues are often in default or have other marked
     shortcomings.
 
C
     Bonds which are rated C are the lowest rated class of bonds, and issues so
     rated can be regarded as having extremely poor prospects of ever attaining
     any real investment standing.
 
Moody's bond ratings, where specified, are applied to senior bank obligations
and insurance company senior policyholder and claims obligations with an
original maturity in excess of one year. Obligations relying upon support
mechanisms such as letters-of-credit and bonds of indemnity are excluded unless
explicitly rated.
 
                                                                             A-1
<PAGE>
Obligations of a branch of a bank are considered to be domiciled in the country
in which the branch is located. Unless noted as an exception, Moody's rating on
a bank's ability to repay senior obligations extends only to branches located in
countries which carry a Moody's sovereign rating. Such branch obligations are
rated at the lower of the bank's rating or Moody's sovereign rating for the bank
deposits for the country in which the branch is located.
 
When the currency in which an obligation is denominated is not the same as the
currency of the country in which the obligation is domiciled, Moody's ratings do
not incorporate an opinion as to whether payment of the obligation will be
affected by the actions of the government controlling the currency of
denomination. In addition, risk associated with bilateral conflicts between an
investor's home country and either the issuer's home country or the country
where an issuer branch is located are not incorporated into Moody's ratings.
 
Moody's makes no representation that rated bank obligations or insurance company
obligations are exempt from registration under the U.S. Securities Act of 1933
or issued in conformity with any other applicable law or regulation. Nor does
Moody's represent that any specific bank or insurance company obligation is
legally enforceable or is a valid senior obligation of a rated issuer.
 
Moody's ratings are opinions, not recommendations to buy or sell, and their
accuracy is not guaranteed. A rating should be weighed solely as one factor in
an investment decision and you should make your own study and evaluation of any
issuer whose securities or debt obligations you consider buying or selling.
 
NOTE:  Moody's applies numerical modifiers, 1, 2 and 3 in each generic rating
classification from Aa through B in its corporate bond rating system. The
modifier 1 indicates that the security ranks in the higher end of its generic
rating category; the modifier 2 indicates a mid-range ranking; and the modifier
3 indicates that the issue ranks in the lower end of its generic rating
category.
 
DESCRIPTION OF STANDARD & POOR'S LONG-TERM RATINGS
 
INVESTMENT GRADE
 
AAA
     Debt rated 'AAA' has the highest rating assigned by S&P. Capacity to pay
     interest and repay principal is extremely strong.
 
AA
     Debt rated 'AA' has a very strong capacity to pay interest and repay
     principal and differs from the highest rated debt only in small degree.
 
A
     Debt rated 'A' has a strong capacity to pay interest and repay principal,
     although it is somewhat more susceptible to adverse effects of changes in
     circumstances and economic conditions than debt in higher-rated categories.
 
BBB
     Debt rated 'BBB' is regarded as having an adequate capacity to pay interest
     and repay principal. Whereas it normally exhibits adequate protection
     parameters, adverse economic conditions or changing circumstances are more
     likely to lead to a weakened capacity to pay interest and repay principal
     for debt in this category than in higher rated categories.
 
                                                                             A-2
<PAGE>
SPECULATIVE GRADE
 
Debt rated 'BB', 'B', 'CCC', 'CC', and 'C' is regarded as having predominantly
speculative characteristics with respect to capacity to pay interest and repay
principal. 'BB' indicates the least degree of speculation and 'C' the highest
degree of speculation. While such debt will likely have some quality and
protective characteristics, these are outweighed by large uncertainties or major
risk exposures to adverse conditions.
 
BB
     Debt rated 'BB' has less near-term vulnerability to default than other
     speculative grade debt. However, it faces major ongoing uncertainties or
     exposure to adverse business, financial, or economic conditions that could
     lead to inadequate capacity to meet timely interest and principal payments.
     The 'BB' rating category is also used for debt subordinated to senior debt
     that is assigned an actual or implied 'BBB-' rating.
 
B
     Debt rate 'B' has greater vulnerability to default but presently has the
     capacity to meet interest payments and principal repayments. Adverse
     business, financial, or economic conditions would likely impair capacity or
     willingness to pay interest and repay principal. The 'B' rating category
     also is used for debt subordinated to senior debt that is assigned an
     actual or implied 'BB' or 'BB-' rating.
 
CCC
     Debt rated 'CCC' has a current identifiable vulnerability to default, and
     is dependent on favorable business, financial, and economic conditions to
     meet timely payment of interest and repayment of principal. In the event of
     adverse business, financial, or economic conditions, it is not likely to
     have the capacity to pay interest and repay principal. The 'CCC' rating
     category also is used for debt subordinated to senior debt that is assigned
     an actual or implied 'B' or 'B-' rating.
 
CC
     The rating 'CC' is typically applied to debt subordinated to senior debt
     which is assigned an actual or implied 'CCC' rating.
 
C
     The rating 'C' is typically applied to debt subordinated to senior debt
     which is assigned an actual or implied 'CCC-' debt rating. The 'C' rating
     may be used to cover a situation where a bankruptcy petition has been
     filed, but debt service payments are continued.
 
CI
     Debt rated 'CI' is reserved for income bonds on which no interest is being
     paid.
 
D
     Debt is rated 'D' when the issue is in payment default, or the obligor has
     filed for bankruptcy. The 'D' rating is used when interest or principal
     payments are not made on the date due, even if the applicable grace period
     has not expired, unless S&P believes that such payments will be made during
     such grace period.
 
Plus (+) or minus (-): The ratings from 'AA' to 'CCC' may be modified by the
addition of a plus or minus sign to show relative standing within the major
rating categories.
 
DESCRIPTION OF DUFF & PHELPS' LONG-TERM DEBT RATINGS
 
AAA
     Highest credit quality. The risk factors are negligible, being only
     slightly more than for risk-free U.S. Treasury debt.
 
AA+
AA-
     High credit quality. Protection factors are strong. Risk is modest but may
     vary slightly from time to time because of economic conditions.
 
                                                                             A-3
<PAGE>
A+
A-
     Protection factors are average but adequate. However, risk factors are more
     variable and greater in periods of economic stress.
 
BBB+
BBB-
     Below average protection factors but still considered sufficient for
     prudent investment. Considerable variability in risk during economic
     cycles.
 
BB+
BB
BB-
     Below investment grade but deemed likely to meet obligations when due.
     Present or prospective financial protection factors fluctuate according to
     industry conditions or company fortunes. Overall quality may move up or
     down frequently within this category.
 
B+
B
B-
     Below investment grade and possessing risk that obligations will not be met
     when due. Financial protection factors will fluctuate widely according to
     economic cycles, industry conditions and/or company fortunes. Potential
     exists for frequent changes in the rating within this category or into a
     higher or lower rating grade.
 
CCC
     Well below investment grade securities. Considerable uncertainty exists as
     to timely payment of principal, interest or preferred dividends. Protection
     factors are narrow and risk can be substantial with unfavorable economic/
     industry conditions, and/or with unfavorable company developments.
 
DD
     Defaulted debt obligations. Issuer failed to meet scheduled principal
     and/or interest payments.
 
DP
     Preferred stock with dividend arrearages.
 
DESCRIPTION OF FITCH'S LONG-TERM RATINGS
 
INVESTMENT GRADE BOND
 
AAA
     Bonds considered to be investment grade and of the highest credit quality.
     The obligor has an exceptionally strong ability to pay interest and repay
     principal, which is unlikely to be affected by reasonably foreseeable
     events.
 
AA
     Bonds considered to be investment grade and of very high credit quality.
     The obligor's ability to pay interest and repay principal is very strong,
     although not quite as strong as bonds rated 'AAA'. Because bonds rated in
     the 'AAA' and 'AA' categories are not significantly vulnerable to
     foreseeable future developments, short-term debt of these issuers is
     generally rated 'F-1+'.
 
A
     Bonds considered to be investment grade and of high credit quality. The
     obligor's ability to pay interest and repay principal is considered to be
     strong, but may be more vulnerable to adverse changes in economic
     conditions and circumstances than bonds with higher ratings.
 
BBB
     Bonds considered to be investment grade and of satisfactory credit quality.
     The obligor's ability to pay interest and repay principal is considered to
     be adequate. Adverse changes in economic conditions and circumstances,
     however, are more likely to have adverse impact on these bonds, and
     therefore impair timely payment. The likelihood that the ratings of these
     bonds will fall below investment grade is higher than for bonds with higher
     ratings.
 
                                                                             A-4
<PAGE>
SPECULATIVE GRADE BOND
 
BB
     Bonds are considered speculative. The obligor's ability to pay interest and
     repay principal may be affected over time by adverse economic changes.
     However, business and financial alternatives can be identified which could
     assist the obligor in satisfying its debt service requirements.
 
B
     Bonds are considered highly speculative. While bonds in this class are
     currently meeting debt service requirements, the probability of continued
     timely payment of principal and interest reflects the obligor's limited
     margin of safety and the need for reasonable business and economic activity
     throughout the life of the issue.
 
CCC
     Bonds have certain identifiable characteristics which, if not remedied, may
     lead to default. The ability to meet obligations requires an advantageous
     business and economic environment.
 
CC
     Bonds are minimally protected. Default in payment of interest and/or
     principal seems probable over time.
 
C
     Bonds are in imminent default in payment of interest or principal.
 
DDD, DD, AND D
               Bonds are in default on interest and/or principal payments. Such
               bonds are extremely speculative and should be valued on the basis
               of their ultimate recovery value in liquidation or reorganization
               of the obligor. 'DDD' represents the highest potential for
               recovery on these bonds, and 'D' represents the lowest potential
               for recovery.
 
PLUS (+) MINUS (-)
               Plus and minus signs are used with a rating symbol to indicate
               the relative position of a credit within the rating category.
               Plus and minus signs, however, are not used in the 'AAA', 'DDD',
               'DD', or 'D' categories.
 
DESCRIPTION OF IBCA'S LONG-TERM RATINGS
 
AAA
     Obligations for which there is 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 substantially.
 
AA
     Obligations for which there is a very low expectation of investment risk.
     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.
 
A
     Obligations for which there is a low expectation of investment risk.
     Capacity for timely repayment of principal and interest is strong, although
     adverse changes in business, economic or financial conditions may lead to
     increased investment risk.
 
BBB
     Obligations for which there is currently a low expectation of investment
     risk. Capacity for timely repayment of principal and interest is adequate,
     although adverse changes in business, economic or financial conditions are
     more likely to lead to increased investment risk than for obligations in
     other categories.
 
                                                                             A-5
<PAGE>
BB
     Obligations for which there is a possibility of investment risk developing.
     Capacity for timely repayment of principal and interest exists, but is
     susceptible over time to adverse changes in business, economic or financial
     conditions.
 
B
     Obligations for which investment risk exists. Timely repayment of principal
     and interest is not sufficiently protected against adverse changes in
     business, economic or financial conditions.
 
CCC
     Obligations for which there is a current perceived possibility of default.
     Timely repayment of principal and interest is dependent on favorable
     business, economic or financial conditions.
 
CC
     Obligations which are highly speculative or which have a high risk of
     default.
 
C
     Obligations which are currently in default.
 
NOTES:
     "+" or "-" may be appended to a rating to denote relative status within
     major rating categories.
 
      Ratings of BB and below are assigned where it is considered that
speculative characteristics are present.
 
DESCRIPTION OF THOMSON BANKWATCH'S LONG-TERM DEBT RATINGS
 
INVESTMENT GRADE
 
AAA
     The highest category; indicates that the ability to repay principal and
     interest on a timely basis is very high.
 
AA
     The second-highest category; indicates a superior ability to repay
     principal and interest on a timely basis, with limited incremental risk
     compared to issues rated in the highest category.
 
A
     The third-highest category; indicates the ability to repay principal and
     interest is strong. Issues rated "A" could be more vulnerable to adverse
     developments (both internal and external) than obligations with higher
     ratings.
 
BBB
     The lowest investment-grade category; indicates an acceptable capacity to
     repay principal and interest. Issues rated "BBB" are, however, more
     vulnerable to adverse developments (both internal and external) than
     obligations with higher ratings.
 
NON-INVESTMENT GRADE
 
(Issues regarded as having speculative characteristics in the likelihood of
timely repayment of principal and interest.)
 
BB
     While not investment grade, the "BB" rating suggests that the likelihood of
     default is considerably less than for lower-rated issues. However, there
     are significant uncertainties that could affect the ability to adequately
     service debt obligations.
 
B
     Issues rated "B" show a higher degree of uncertainty and therefore greater
     likelihood of default than higher-rated issues. Adverse developments could
     well negatively affect the payment of interest and principal on a timely
     basis.
 
CCC
     Issues rated "CCC" clearly have a high likelihood of default, with little
     capacity to address further adverse changes in financial circumstances.
 
                                                                             A-6
<PAGE>
CC
     "CC" is applied to issues that are subordinate to other obligations rated
     "CCC" and are afforded less protection in the event of bankruptcy or
     reorganization.
 
D
     Default
 
      Ratings in the Long-Term Debt categories may include a plus (+) or minus
(-) designation, which indicates where within the respective category the issue
is placed.

                                   THE TRUST
 
    SEI Institutional Investments Trust (the "Trust") is an open-end management
investment company that has diversified and non-diversified funds. The Trust was
organized as a Massachusetts business trust under a Declaration of Trust dated
March 1, 1995. The Declaration of Trust permits the Trust to offer separate
series ("funds") of units of beneficial interest ("shares") and different
classes of shares. Each share of each fund represents an equal proportionate
interest in that fund with each other share of that fund.
 
    This Statement of Additional Information relates to the following funds:
Large Cap, Small Cap, Core Fixed Income, High Yield Bond, International Fixed
Income, Emerging Markets Equity and International Equity Funds (each a "Fund"
and, together, the "Funds").
 
                      DESCRIPTION OF PERMITTED INVESTMENTS
 
   
    AMERICAN DEPOSITARY RECEIPTS ("ADRS"), EUROPEAN DEPOSITARY RECEIPTS ("EDRS")
AND GLOBAL DEPOSITARY RECEIPTS ("GDRS")--Holders of an unsponsored depositary
receipt generally bear all the costs of the unsponsored facility. The depositary
of an unsponsored facility frequently is under no obligation to distribute
shareholder communications received from the issuer of the deposited security or
to pass through to the holders of the receipts voting rights with respect to the
deposited securities.
    
 
    ASSET-BACKED SECURITIES--securities backed by automobile receivables and
credit-card receivables and other securities backed by other types of
receivables or other assets. Credit support for asset-backed securities may be
based on the underlying assets and/or provided through credit enhancements by a
third party. Credit enhancement techniques include letters of credit, insurance
bonds, limited guarantees (which are generally provided by the issuer),
senior-subordinated structures and overcollateralization. The Core Fixed Income,
High Yield Bond and International Fixed Income Funds may invest in asset-backed
securities.
 
    Asset-backed securities are not issued or guaranteed by the United States
Government or its agencies or instrumentalities; however, the payment of
principal and interest on such obligations may be guaranteed up to certain
amounts and for a certain period by a letter of credit issued by a financial
institution (such as a bank or insurance company) unaffiliated with the issuers
of such securities. The purchase of asset-backed securities raises risk
considerations peculiar to the financing instruments underlying such securities.
For example, there is a risk that another party could acquire an interest in the
obligations superior to that of the holders of the asset-backed securities.
There also is the possibility that recoveries on repossessed collateral may not,
in some cases, be available to support payments on those securities.
Asset-backed securities entail prepayment risk, which may vary depending on the
type of asset, but is generally less than the prepayment risk associated with
mortgage-backed securities. In addition, credit card receivables are unsecured
obligations of the card holder.
 
    The market for asset-backed securities is at a relatively early stage of
development. Accordingly, there may be limited secondary market for such
securities.
 
    BANKERS' ACCEPTANCES--a bill of exchange or time draft 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--a negotiable interest bearing instrument with a
specific maturity. Certificates of deposit 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.
 
                                      S-3
<PAGE>
    COMMERCIAL PAPER--the term used to designate unsecured short-term promissory
notes issued by corporations and other entities. Maturities on these issues vary
from a few days to nine months. (See "Description of Ratings").
 
   
    EQUITY SECURITIES--Equity securities represent ownership interests in a
company or corporation and consist of common stock, preferred stock, warrants
and other rights to acquire such instruments. Equity securities may be listed on
exchanges or traded in the over-the-counter market. Investments in common stocks
are subject to market risks which may cause their prices to fluctuate over time.
The value of convertible securities is also affected by prevailing interest
rates, the credit quality of the issuer and any call provisions. Changes in the
value of fund securities will not necessarily affect cash income derived from
these securities, but will affect a Fund's net asset value.
    
 
   
    Investments in the equity securities of small capitalization companies
involves greater risk than is customarily associated with larger, more
established companies due to the greater business risks of small size, limited
markets and financial resources, narrow product lines and the frequent lack of
depth of management. The securities of small companies are often traded
over-the-counter and may not be traded in volumes typical on a national
securities exchange. Consequently, the securities of smaller companies may have
limited market stability and may be subject to more abrupt or erratic market
movements than securities of larger, more established growth companies or the
market averages in general.
    
 
   
    FOREIGN SECURITIES--may consist of obligations of foreign branches of U.S.
banks and foreign banks, including European Certificates of Deposit, European
Time Deposits, Canadian Time Deposits and Yankee Certificates of Deposit and
investments in Canadian Commercial Paper, foreign securities and Europaper. In
addition, a Fund may invest in American Depositary Receipts ("ADRs") traded on
registered exchanges or NASDAQ. While a Fund expects to invest primarily in
sponsored ADRs, a joint arrangement between the issuer and the depositary, some
ADRs may be unsponsored. These instruments may subject a Fund 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 the exchange rates, or the adoption of other foreign governmental
restrictions which might adversely affect the payment of principal and interest
on such obligations. Such investments may also entail higher custodial fees and
sales commissions than domestic investments. Foreign issuers of securities or
obligations are often subject to accounting treatment and engage in business
practices different from those respecting domestic issuers of similar securities
or obligations. Foreign branches of U.S. banks and foreign banks may be subject
to less stringent reserve requirements than those applicable to domestic
branches of U.S. banks.
    
 
    FORWARD FOREIGN CURRENCY CONTRACTS--involve an obligation to purchase or
sell a specified currency at a future date at a price set at the time of the
contract. Forward currency contracts do not eliminate fluctuations in the values
of fund securities but rather allow a Fund to establish a rate of exchange for a
future point in time.
 
   
    When entering into a contract for the purchase or sale of a security in a
foreign currency, a Fund may enter into a foreign forward currency contract for
the amount of the purchase or sale price to protect against variations, between
the date the security is purchased or sold and the date on which payment is made
or received, in the value of the foreign currency relative to the United States
Dollar or other foreign currency.
    
 
    Also, when the Money Manager anticipates that a particular foreign currency
may decline substantially relative to the United States dollar or other leading
currencies, in order to reduce risk, a Fund may enter into a forward contract to
sell, for a fixed amount, the amount of foreign currency approximating the value
of its securities denominated in such foreign currency. With respect to any such
forward foreign currency contract, it generally will not be possible to match
precisely the amount covered by that contract
 
                                      S-4
<PAGE>
   
and the value of the securities involved due to changes in the values of such
securities resulting from market movements between the date the forward contract
is entered into and the date it matures. In addition, while forward currency
contracts may offer protection from losses resulting from declines in value of a
particular foreign currency, they also limit potential gains which might result
from increases in the value of such currency. A Fund will also incur costs in
connection with forward foreign currency contracts and conversions of foreign
currencies into United States dollars. The Fund will place assets in a
segregated account to assure that its obligations under forward foreign currency
contracts are covered.
    
 
   
    FUTURES AND OPTIONS ON FUTURES--A Fund may enter into futures contracts and
options on futures contracts traded on an exchange regulated by the Commodities
Futures Trading Commission ("CFTC"), as long as, to the extent that such
transactions are not for "bona fide hedging purposes," the aggregate initial
margin and premiums on such positions (excluding the amount by which such
options are in the money) do not exceed 5% of a Fund's net assets. A Fund may
buy and sell futures contracts and related options to manage its exposure to
changing interest rates and securities prices. Some strategies reduce a Fund's
exposure to price fluctuations, while others tend to increase its market
exposure. Futures and options on futures can be volatile instruments and involve
certain risks that could negatively impact a Fund's return.
    
 
    GNMA SECURITIES--securities issued by the Government National Mortgage
Association ("GNMA"), a wholly-owned U.S. Government corporation, are guaranteed
by GNMA as to 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 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, a Fund
will receive monthly scheduled payments of principal and interest. In addition,
a Fund 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.
 
   
    LOWER RATED SECURITIES--lower-rated bonds are commonly referred to as "junk
bonds" or high yield/high risk securities. These securities are rated "Baa" or
"BBB" or lower by an NRSRO. Each Fund may invest in securities rated as low as
"C" by Moody's or "D" by S&P. These ratings indicate that the obligations are
speculative and may be in default. In addition, each Fund may invest in unrated
securities subject to the restrictions stated in the Prospectus.
    
 
    GROWTH OF HIGH YIELD BOND, HIGH-RISK BOND MARKET.  The widespread expansion
of government, consumer and corporate debt within the U.S. economy has made the
corporate sector more vulnerable to economic downturns or increased interest
rates. Further, an economic downturn could severely disrupt the market for lower
rated bonds and adversely affect the value of outstanding bonds and the ability
of the issuers to repay principal and interest.
 
    SENSITIVITY TO INTEREST RATE AND ECONOMIC CHANGES.  Lower rated bonds are
very sensitive to adverse economic changes and corporate developments. During an
economic down turn or substantial period of rising interest rates, highly
leveraged issuers may experience financial stress that would adversely affect
their ability to service their principal and interest payment obligations, to
meet projected business goals,
 
                                      S-5
<PAGE>
and to obtain additional financing. If the issuer of a bond defaulted on its
obligations to pay interest or principal or entered into bankruptcy proceedings,
a Fund may incur losses or expenses in seeking recovery of amounts owed to it.
In addition, periods of economic uncertainty and change can be expected to
result in increased volatility of market prices of high-yield, high-risk bonds
and a Fund's net asset value.
 
    PAYMENT EXPECTATIONS.  High-yield, high-risk bonds may contain redemption or
call provisions. If an issuer exercised these provisions in a declining interest
rate market, a Fund would have to replace the security with a lower yielding
security, resulting in a decreased return for investors. Conversely, a high-
yield, high-risk bond's value will decrease in a rising interest rate market, as
will the value of a Fund's assets. If a Fund experiences significant unexpected
net redemptions, this may force it to sell high-yield, high-risk bonds without
regard to their investment merits, thereby decreasing the asset base upon which
expenses can be spread and possibly reducing the Fund's rate of return.
 
   
    LIQUIDITY AND VALUATION.  There may be little trading in the secondary
market for particular bonds, which may affect adversely a Fund's ability to
value accurately or dispose of such bonds. Adverse publicity and investor
perception, whether or not based on fundamental analysis, may decrease the value
and liquidity of high-yield, high-risk bonds, especially in a thin market.
    
 
    TAXES.  A Fund may purchase debt securities (such as zero-coupon or
pay-in-kind securities) that contain original issue discount. Original issue
discount that accretes in a taxable year is treated as earned by a Fund and
therefore is subject to the distribution requirements of the Internal Revenue
Code of 1986, as amended (the "Code"). Because the original issue discount
earned by a Fund in a taxable year may not be represented by cash income, the
Fund may have to dispose of other securities and use the proceeds to make
distributions to shareholders.
 
   
    MORTGAGE-BACKED SECURITIES--The Funds may invest in mortgage-backed
securities, which represent pools of mortgage loans assembled for sale to
investors by various governmental agencies such as GNMA and government-related
organizations such as Fannie Mae and the Federal Home Loan Mortgage Corporation
("FHLMC"). In addition, the High Yield Bond may invest in pools of mortgage
loans from nongovernmental issuers such as commercial banks, savings and loan
institutions, mortgage bankers, and private mortgage insurance companies.
Although certain mortgage-backed securities are guaranteed by a third party or
otherwise similarly secured, the market value of the security, which may
fluctuate, is not so secured. If a Fund purchases a mortgage-backed security at
a premium, that portion may be lost if there is a decline in the market value of
the security whether resulting from changes in interest rates or prepayments in
the underlying mortgage collateral. As with other interest-bearing securities,
the prices of such securities are inversely affected by changes in interest
rates. However, though the value of a mortgage-backed security may decline when
interest rates rise, the converse is not necessarily true since in periods of
declining interest rates the mortgages underlying the securities are prone to
prepayment. For this and other reasons, a mortgage-backed security's stated
maturity may be shortened by unscheduled prepayments on the underlying mortgages
and, therefore, it is not possible to predict accurately the security's return
to a Fund. In addition, regular payments received in respect of mortgage-backed
securities include both interest and principal. No assurance can be given as to
the return a Fund will receive when these amounts are reinvested.
    
 
    A Fund may also invest in mortgage-backed securities that are collateralized
mortgage obligations structured on pools of mortgage pass-through certificates
or mortgage loans.
 
   
    There are a number of important differences among the agencies and
instrumentalities of the U.S. Government that issue mortgage-backed securities
and among the securities that they issue. Mortgage-backed securities issued by
GNMA include GNMA Mortgage Pass-Through Certificates (also known as "Ginnie
Maes") which are guaranteed as to the timely payment of principal and interest
by GNMA and is backed by the full faith and credit of the United States. GNMA
certificates also are supported by the authority of GNMA to borrow funds from
the U.S. Treasury to make payments under its guarantee. Mortgage-backed
securities issued by Fannie Mae include Fannie Mae Guaranteed Mortgage Pass-
    
 
                                      S-6
<PAGE>
   
Through Certificates (also known as "Fannie Maes") which are solely the
obligations of Fannie Mae and are not backed by or entitled to the full faith
and credit of the United States. Fannie Mae is a government-sponsored
organization owned entirely by private stockholders. Fannie Maes are guaranteed
as to timely payment of the principal and interest by Fannie Mae.
Mortgage-backed securities issued by FHLMC include FHLMC Mortgage Participation
Certificates (also known as "Freddie Macs" or "PCs"). FHLMC is a corporate
instrumentality of the United States, created pursuant to an Act of Congress,
which is owned entirely by Federal Home Loan Banks. Freddie Macs are not
guaranteed by the United States or by any Federal Home Loan Banks and do not
constitute a debt or obligation of the United States or of any Federal Home Loan
Bank. Freddie Macs entitle the holder to timely payment of interest, which is
guaranteed by FHLMC. FHLMC guarantees either ultimate collection or timely
payment of all principal payments on the underlying mortgage loans. FHLMC has in
the past guaranteed only the ultimate collection of principal of the underlying
mortgage loan; however, FHLMC now issues mortgage-backed securities (FHLMC Gold
PCs) which also guarantee timely payment of monthly principal reductions.
Government and private guarantees do not extend to the securities' value, which
is likely to vary inversely with fluctuations in interest rates. When FHLMC does
not guarantee timely payment of principal, FHLMC may remit the amount due on
account of its guarantee of ultimate payment of principal at any time after
default on an underlying mortgage, but in no event later than one year after it
becomes payable. The Core Fixed Income, High Yield Bond and International Fixed
Income Funds may, consistent with their respective investment objectives and
policies, invest in mortgage-backed securities issued or guaranteed by the U.S.
Government or its agencies or instrumentalities. The High Yield Bond Fund may
also purchase mortgage-backed securities issued by non-governmental entities as
set forth in the Prospectus.
    
 
    PARALLEL PAY SECURITIES; PAC BONDS:  Parallel pay CMOs and REMICS are
structured to provide payments of principal on each payment date to more than
one class. These simultaneous payments are taken into account in calculating the
stated maturity date or final distribution date of each class, which must be
retired by its stated maturity date or final distribution date, but may be
retired earlier. It is possible that payments on one class of parallel pay
security may be deferred or subordinated to payments on other classes. Planned
Amortization Class CMOs ("PAC Bonds") generally require payments of a specified
amount of principal on each payment date. PAC Bonds are always parallel pay CMOs
with the required principal payment on such securities having the highest
priority after interest has been paid to all classes.
 
   
    MORTGAGE DOLLAR ROLLS--Mortgage "dollar rolls" are transactions in which
mortgage-backed securities are sold for delivery in the current month and the
seller simultaneously contracts to repurchase substantially similar securities
on a specified future date. Any difference between the sale price and the
purchase price is netted against the interest income foregone on the securities
sold to arrive at an implied borrowing rate. Alternatively, the sale and
purchase transactions can be executed at the same price, with the Fund being
paid a fee as consideration for entering into the commitment to purchase.
Mortgage dollar rolls may be renewed prior to cash settlement and initially may
involve only a firm commitment agreement by the Fund to buy a security. If the
broker-dealer to whom the Fund sells the security becomes insolvent, the Fund's
right to repurchase the security may be restricted. Other risks involved in
entering into mortgage dollar rolls include the risk that the value of the
security may change adversely over the term of the mortgage dollar roll and that
the security the Fund is required to repurchase may be worth less than the
security that the Fund originally held.
    
 
   
    To avoid any leveraging concerns, the Fund will place U.S. Government or
other liquid securities in a segregated account in an amount sufficient to cover
its repurchase obligation.
    
 
    OBLIGATIONS OF SUPRANATIONAL AGENCIES--may be purchased by the Core Fixed
Income, International Fixed Income, Emerging Markets Equity and International
Equity Funds. Currently, each Fund intends to invest only in obligations issued
or guaranteed by the Asian Development Bank, Inter-American Development Bank,
European Coal and Steel Community, European Economic Community, European
Investment Bank and the Nordic Investment Bank.
 
                                      S-7
<PAGE>
   
    OPTIONS--The initial purchase (sale) of an option contract is an "opening
transaction." In order to close out an option position, a Fund may enter into a
"closing transaction," which is simply the sale (purchase) of an option contract
on the same security with the same exercise price and expiration date as the
option contract originally opened. If a Fund is unable to effect a closing
purchase transaction with respect to an option it has written, it will not be
able to sell the underlying security until the option expires or the Fund
delivers the security upon exercise.
    
 
   
    A Fund may purchase put and call options on securities to protect against a
decline in the market value of the securities in its portfolio or to anticipate
an increase in the market value of securities that the Fund may seek to purchase
in the future. A Fund purchasing put and call options pays a premium therefor.
If price movements in the underlying securities are such that exercise of the
options would not be profitable for the Fund, loss of the premium paid may be
offset by an increase in the value of the Fund's securities or by a decrease in
the cost of acquisition of securities by the Fund.
    
 
   
    A Fund may write covered call options on securities as a means of increasing
the yield on its fund and as a means of providing limited protection against
decreases in its market value. When a Fund writes an option, if the underlying
securities do not increase or decrease to a price level that would make the
exercise of the option profitable to the holder thereof, the option generally
will expire without being exercised and the Fund will realize as profit the
premium received for such option. When a call option of which a Fund is the
writer is exercised, the Fund will be required to sell the underlying securities
to the option holder at the strike price, and will not participate in any
increase in the price of such securities above the strike price. When a put
option of which a Fund is the writer is exercised, the Fund will be required to
purchase the underlying securities at a price in excess of the market value of
such securities.
    
 
   
    A segregated account is maintained to cover the difference between the
closing price of the index and the exercise price of the index option, expressed
in dollars multiplied by a specified number. Thus, unlike options on individual
securities, the ability of a Fund to enter into closing transactions depends
upon the existence of a liquid secondary market for such transactions.
    
 
   
    A Fund may purchase and write options on an exchange or over-the-counter.
Over-the-counter options ("OTC options") differ from exchange-traded options in
several respects. They are transacted directly with dealers and not with a
clearing corporation, and therefore entail the risk of non-performance by the
dealer. OTC options are available for a greater variety of securities and for a
wider range of expiration dates and exercise prices than are available for
exchange-traded options. Because OTC options are not traded on an exchange,
pricing is done normally by reference to information from a market maker. It is
the position of the SEC that OTC options are generally illiquid.
    
 
   
    PUT TRANSACTIONS--All of the Funds may purchase securities at a price which
would result in a yield to maturity lower than generally offered by the seller
at the time of purchase when a Fund can simultaneously acquire the right to sell
the securities back to the seller, the issuer or a third party (the "writer") at
an agreed-upon price at any time during a stated period or on a certain date.
Such a right is generally denoted as a "standby commitment" or a "put." The
purpose of engaging in transactions involving puts is to maintain flexibility
and liquidity to permit a Fund to meet redemptions and remain as fully invested
as possible in municipal securities. A Fund reserves the right to engage in put
transactions. The right to put the securities depends on the writer's ability to
pay for the securities at the time the put is exercised. A Fund would limit its
put transactions to institutions which the Fund's Money Managers believe present
minimum credit risks, and the Fund's Money Managers would use their best efforts
to initially determine and continue to monitor the financial strength of the
sellers of the options by evaluating their financial statements and such other
information as is available in the marketplace. It may, however, be difficult to
monitor the financial strength of the writers because adequate current financial
information may not be available. In the event that any writer is unable to
honor a put for financial reasons, a Fund would be a general creditor (I.E., on
a parity with all other unsecured creditors) of the writer. Furthermore,
particular provisions of the contract between a Fund and the writer may excuse
the writer from repurchasing the securities; for example, a change in the
published rating of the underlying municipal securities or
    
 
                                      S-8
<PAGE>
any similar event that has an adverse effect on the issuer's credit or a
provision in the contract that the put will not be exercised except in certain
special cases, for example, to maintain fund liquidity. A Fund could, however,
at any time sell the underlying portfolio security in the open market or wait
until the portfolio security matures, at which time it should realize the full
par value of the security.
 
    The securities purchased subject to a put may be sold to third persons at
any time, even though the put is outstanding, but the put itself, unless it is
an integral part of the security as originally issued, may not be marketable or
otherwise assignable. Therefore, the put would have value only to that
particular Fund. Sale of the securities to third parties or lapse of time with
the put unexercised may terminate the right to put the securities. Prior to the
expiration of any put option, a Fund could seek to negotiate terms for the
extension of such an option. If such a renewal cannot be negotiated on terms
satisfactory to the Fund, the Fund could, of course, sell the portfolio
security. The maturity of the underlying security will generally be different
from that of the put. There will be no limit to the percentage of fund
securities that a Fund may purchase subject to a put but the amount paid
directly or indirectly for puts which are not integral parts of the security as
originally issued will not exceed 1/2 of 1% of the value of the total assets of
such Fund calculated immediately after any such put is acquired. For the purpose
of determining the "maturity" of securities purchased subject to an option to
put, and for the purpose of determining the dollar-weighted average maturity of
a Fund including such securities, the Trust will consider "maturity" to be the
first date on which it has the right to demand payment from the writer of the
put although the final maturity of the security is later than such date.
 
   
    RECEIPTS--interests in separately traded interest and principal component
parts of U.S. Government obligations that are issued by banks or brokerage firms
and are created by depositing U.S. Government obligations into a special account
at a custodian bank. The custodian holds the interest and principal payments for
the benefit of the registered owners of the certificates or receipts. The
custodian arranges for the issuance of the certificates or receipts evidencing
ownership and maintains the register. Receipts include "Treasury Receipts"
("TRs"), "Treasury Investment Growth Receipts" ("TIGRs"), and "Certificates of
Accrual on Treasury Securities" ("CATS"). TIGRs and CATS are interests in
private proprietary accounts while TRs and STRIPS (See "U.S. Treasury
Obligations") are interests in accounts sponsored by the U.S. Treasury. Receipts
are sold as zero coupon securities; for more information, see "Zero Coupon
Securities."
    
 
    REPURCHASE AGREEMENTS--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. A Fund involved bears a
risk of loss in the event that the other party to a repurchase agreement
defaults on its obligations and the Fund is delayed or prevented from exercising
its rights to dispose of the collateral securities. A Fund's Money Managers
enter into repurchase agreements only with financial institutions that they deem
to present minimal risk of bankruptcy during the term of the agreement, based on
guidelines that are periodically reviewed by the Board of Trustees. These
guidelines currently permit each Fund 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 a Fund 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. A Fund's
Money Managers will monitor compliance with this requirement. Under all
repurchase agreements entered into by a Fund, the Custodian or its agent must
take possession of the underlying collateral. However, if the seller defaults, a
Fund 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, a Fund
may incur delay and costs in selling the security and may suffer a loss of
principal and interest if the Fund is treated as an unsecured creditor.
 
                                      S-9
<PAGE>
   
    SECURITIES LENDING--in order to generate additional income, a Fund may lend
the securities in which it is invested pursuant to agreements requiring that the
loans be continuously secured by cash, securities of the U.S. Government or its
agencies, or any combination of cash and such securities, as collateral equal to
at least the market value at all times of the loaned securities. A Fund will
continue to receive interest on the loaned securities while simultaneously
earning interest on the investment of the cash collateral in U.S. Government
securities. However, a Fund will normally pay lending fees to such
broker-dealers and related expenses from the interest earned on invested
collateral. There may be risks of delay in receiving additional collateral or
risks of delay in recovery of the securities or even loss of rights in the
collateral should the borrower of the securities fail financially. However,
loans are made only to borrowers deemed by the Fund's Money Managers to be of
good standing and when, in the judgment of the Fund's Money Managers, the
consideration which can be earned currently from such securities loans justifies
the attendant risk. Any loan may be terminated by either party upon reasonable
notice to the other party. Each Fund may use the Distributor as a broker in
these transactions.
    
 
   
    SHORT SALES--Selling securities short involves selling securities the Fund
does not own (but has borrowed) in anticipation of a decline in the market price
of such securities. To deliver the securities to the buyer, the seller must
arrange through a broker to borrow the securities and, in so doing, the seller
becomes obligated to replace the securities borrowed at their market price at
the time of replacement. In a short sale, the proceeds the seller receives from
the sale are retained by a broker until the seller replaces the borrowed
securities. The seller may have to pay a premium to borrow the securities and
must pay any dividends or interest payable on the securities until they are
replaced.
    
 
    SWAPS, CAPS, FLOORS AND COLLARS--are sophisticated hedging instruments that
typically involve a small investment of cash relative to the magnitude of risk
assumed. As a result, swaps can be highly volatile and have a considerable
impact on a Fund's performance. Swap agreements are subject to risks related to
the counterparty's ability to perform, and may decline in value if the
counterparty's creditworthiness deteriorates. A Fund may also suffer losses if
it is unable to terminate outstanding swap agreements or reduce its exposure
through offsetting transactions. Any obligation a Fund may have under these
types of arrangements will be covered by setting aside liquid, high grade
securities in a segregated account. A Fund will enter into swaps only with
counterparties believed to be creditworthy.
 
   
    In a typical interest rate swap, one party agrees to make regular payments
equal to a floating interest rate times a "notional principal amount," in return
for payments equal to a fixed rate times the same amount, for a specific period
of time. Swaps may also depend on other prices or rates, such as the value of an
index or mortgage prepayment rates.
    
 
   
    In a typical cap or floor agreement, one party agrees to make payments only
under specified circumstances, usually in return for payment of a fee by the
other party.
    
 
    The buyer of an interest rate cap obtains the right to receive payments to
the extent that a specific interest rate exceeds an agreed-upon level, while the
seller of an interest rate floor is obligated to make payments to the extent
that a specified interest rate falls below an agreed-upon level. An interest
rate collar combines elements of buying a cap and selling a floor.
 
    TIME DEPOSITS--a non-negotiable receipt issued by a bank in exchange for the
deposit of funds. Like a certificate of deposit, it earns a specified rate of
interest over a definite period of time; however, it cannot be traded in the
secondary market.
 
    Time deposits with a withdrawal penalty are considered to be illiquid
securities. The High Yield Bond, International Fixed Income, Emerging Markets
Equity and International Equity Funds may invest in time deposits.
 
    U.S. GOVERNMENT AGENCY OBLIGATIONS--agencies of the United States Government
that issue obligations, including, among others, Export Import Bank of the
United States, Farmers Home Administration, Federal Farm Credit System, Federal
Housing Administration, Government National
 
                                      S-10
<PAGE>
Mortgage Association, Maritime Administration, Small Business Administration and
The Tennessee Valley Authority. A Fund may purchase securities issued or
guaranteed by the GNMA which represent participations in Veterans Administration
and Federal Housing Administration backed mortgage pools.
 
   
    Guarantees of principal by agencies or instrumentalities of the U.S.
Government may be a guarantee of payment at the maturity of the obligation so
that in the event of a default prior to maturity there might not be a market and
thus no means of realizing on the obligation prior to maturity. Guarantees as to
the timely payment of principal and interest do not extend to the value or yield
of these securities or to the value of a Fund's shares.
    
 
    U.S. TREASURY OBLIGATIONS--bills, notes and bonds 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"). No
Fund may actively trade STRIPS. STRIPS are sold as zero coupon securities; for
more information, see "Zero Coupon Securities."
 
   
    VARIABLE AND FLOATING RATE INSTRUMENTS--may involve a demand feature and may
include variable amount master demand notes available through the Custodian, or
otherwise. 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 Fund's managers, be equivalent to the
long-term bond or commercial paper ratings applicable to permitted investments
for each Fund. Each Fund's Money Managers 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. 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 exceeding seven
days may be considered illiquid if there is no secondary market for such
security.
    
 
    In case of obligations which include a put feature at the option of the debt
holder, the date of the put may be used as an effective maturity date for the
purpose of determining weighted average fund maturity.
 
   
    WHEN-ISSUED AND DELAYED DELIVERY SECURITIES--involve the purchase of debt
obligations on a when-issued basis, in which case delivery and payment normally
take place within 45 days after the date of commitment to purchase. The payment
obligation and the interest rate that will be received on the securities are
each fixed at the time the purchaser enters into the commitment. 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 Fund generally purchases securities on a
when-issued or forward commitment basis with the intention of actually acquiring
securities, a Fund may dispose of a when-issued security or forward commitment
prior to settlement if it deems it appropriate to do so. When investing in
when-issued securities, a Fund will not accrue income until delivery of the
securities and will invest in such securities only for purposes of actually
acquiring the securities and not for purposes of leveraging.
    
 
   
    One form of when-issued or delayed-delivery security that a Portfolio may
purchase is a "to be announced" ("TBA") mortgage-backed security. A TBA
mortgage-backed security transaction arises when a mortgage-backed security,
such as a GNMA pass-through security, is purchased or sold with specific pools
that will constitute that GNMA pass-through security to be announced on a future
settlement date.
    
 
    Purchasing obligations on a when-issued basis is a form of leveraging and
can involve a risk that the yields available in the market when the delivery
takes place may actually be higher than those obtained in the transaction
itself. In that case there could be an unrealized loss at the time of delivery.
 
                                      S-11
<PAGE>
   
    A Fund will establish a segregated account and maintain liquid assets in an
amount at least equal in value to that Fund's commitments to purchase
when-issued securities. If the value of these assets declines, the Fund involved
will place additional liquid assets in the account on a daily basis so that the
value of the assets in the account is equal to the amount of such commitments.
    
 
   
    ZERO COUPON SECURITIES--STRIPS and receipts (TRs, TIGRs and CATS) are sold
as zero coupon securities, that is, fixed income securities that have been
stripped of their unmatured interest coupons. Zero coupon securities are sold at
a (usually substantial) discount and redeemed at face value at their maturity
date without interim cash payments of interest or principal. The amount of this
discount is accreted over the life of the security, and the accretion
constitutes the income earned on the security for both accounting and tax
purposes. Because of these features, the market prices of zero coupon securities
are generally more volatile than the market prices of securities that have
similar maturity but that pay interest periodically. Zero coupon securities are
likely to respond to a greater degree to interest rate changes than are non-zero
coupon securities with similar maturity and credit qualities.
    
 
   
    Corporate zero coupon securities are: (i) notes or debentures which do not
pay current interest and are issued at substantial discounts from par value, or
(ii) notes or debentures that pay no current interest until a stated dated one
or more years into the future, after which the issuer is obligated to pay
interest until maturity, usually at a higher rate than if interest were payable
from the date of issuance and may also make interest payments in kind (e.g.,
with identical zero coupon securities). Such corporate zero coupon securities,
in addition to the risks identified above, are subject to the risk of the
issuer's failure to pay interest and repay principal in accordance with the
terms of the obligation. A Fund must accrete the discount or interest on
high-yield bonds structured as zero coupon securities as income even though it
does not receive a corresponding cash interest payment until the security's
maturity or payment date. A Fund may have to dispose of its securities under
disadvantageous circumstances to generate cash, or may have to leverage itself
by borrowing cash to satisfy distribution requirements. A Fund accrues income
with respect to the securities prior to the receipt of cash payments.

                             DESCRIPTION OF RATINGS
 
DESCRIPTION OF MOODY'S SHORT-TERM RATINGS
 
    PRIME-1 Issuers rated Prime-1 (or supporting institutions) have a superior
ability for repayment of senior short-term debt obligations. Prime-1 repayment
ability will often be evidenced by many of the following characteristics:
 
    - Leading market positions in well-established industries.
 
    - High rates of return on funds employed.
 
    - Conservative capitalization structure with moderate reliance on debt and
      ample asset protection.
 
    - Broad margins in earnings coverage of fixed financial charges and high
      internal cash generation.
 
    - Well-established access to a range of financial markets and assured
      sources of alternate liquidity.
 
    PRIME-2 Issuers rated Prime-2 (or supporting institutions) have a strong
ability for repayment of senior short-term debt obligations. This will normally
be evidenced by many of the characteristics cited above but to a lesser degree.
Earnings trends and coverage ratios, while sound, may be more subject to
variation. Capitalization characteristics, while still appropriate, may be more
affected by external conditions. Ample alternate liquidity is maintained.
 
    PRIME-3 Issuers rated Prime-3 (or supporting institutions) have an
acceptable ability for repayment of senior short-term obligations. The effect of
industry characteristics and market compositions may be more pronounced.
Variability in earnings and profitability may result in changes in the level of
debt protection measurements and may require relatively high financial leverage.
Adequate alternate liquidity is maintained.
 
    NOT PRIME Issuers rated Not Prime do not fall within any of the Prime rating
categories.
 
STANDARD & POOR'S SHORT-TERM RATINGS
 
<TABLE>
<S>        <C>
A-1        This highest category indicates that the degree of safety regarding timely payment is
           strong. Debt determined to possess extremely strong safety characteristics is denoted
           with a plus sign (+) designation.
A-2        Capacity for timely payment on issues with this designation is satisfactory. However,
           the relative degree of safety is not as high as for issues designated 'A-1'.
A-3        Debt carrying this designation has an adequate capacity for timely payment. It is,
           however, more vulnerable to the adverse effects of changes in circumstances than
           obligations carrying the higher designations.
B          Debt rated 'B' is regarded as having only speculative capacity for timely payment.
C          This rating is assigned to short-term debt obligations with a doubtful capacity for
           payment.
D          This rating indicates that the obligation is in payment default.

DESCRIPTION OF DUFF & PHELPS' SHORT-TERM RATINGS
 
<TABLE>
<S>        <C>
Duff 1+    Highest certainty of timely payment. Short-term liquidity, including internal
           operating factors and/or access to alternative sources of funds, is outstanding,
           and safety is just below risk-free U.S. Treasury short-term obligations.
Duff 1     Very high certainty of timely payment. Liquidity factors are excellent and
           supported by good fundamental protection factors. Risk factors are minor.
Duff 1-    High certainty of timely payment. Liquidity factors are strong and supported by
           good fundamental protection factors. Risk factors are very small.

GOOD GRADE
 
Duff 2     Good certainty of timely payment. Liquidity factors and company fundamentals are
           sound. Although ongoing funding needs may enlarge total financing requirements,
           access to capital markets is good. Risk factors are small.
 
SATISFACTORY GRADE
 
Duff 3     Satisfactory liquidity and other protection factors qualify issue as to investment
           grade. Risk factors are larger and subject to more variation. Nevertheless, timely
           payment is expected.
 
NON-INVESTMENT GRADE
 
Duff 4     Speculative investment characteristics. Liquidity is not sufficient to insure
           against disruption in debt service. Operating factors and market access may be
           subject to a high degree of variation.
 
DEFAULT
 
Duff 5     Issuer failed to meet scheduled principal and/or interest payments.
 
DESCRIPTION OF FITCH'S SHORT-TERM RATINGS
 
F-1+       Exceptionally Strong Credit Quality. Issues assigned this rating are regarded as
           having the strongest degree of assurance for timely payment.
F-1        Very Strong Credit Quality. Issues assigned this rating reflect an assurance of
           timely payment only slightly less in degree than issues rated 'F-1+'
F-2        Good Credit Quality. Issues assigned this rating have a satisfactory degree of
           assurance for timely payment, but the margin of safety is not as great as for
           issues assigned 'F-1+' and 'F-1' ratings.
F-3        Fair Credit Quality. Issues assigned this rating have characteristics suggesting
           that the degree of assurance for timely payment is adequate, however, near-term
           adverse changes could cause these securities to be rated below investment grade.
F-S        Weak Credit Quality. Issues assigned this rating have characteristics suggesting a
           minimal degree of assurance for timely payment and are vulnerable to near-term
           adverse changes in financial and economic conditions.
D          Default. Issues assigned this rating are in actual or imminent payment default.
LOC        The symbol LOC indicates that the rating is based on a letter of credit issued by
           a commercial bank.
 
DESCRIPTION OF IBCA'S SHORT-TERM RATINGS (UP TO 12 MONTHS)
 
A1+        Obligations supported by the highest capacity for timely repayment.
A1         Obligations supported by a strong capacity for timely repayment.
A2         Obligations supported by a satisfactory capacity for timely repayment, although
           such capacity may be susceptible to adverse changes in business, economic, or
           financial conditions.
A3         Obligations supported by an adequate capacity for timely repayment. Such capacity
           is more susceptible to adverse changes in business, economic, or financial
           conditions than for obligations in higher categories.
B          Obligations for which the capacity for timely repayment is susceptible to adverse
           changes in business, economic, or financial conditions.
C          Obligations for which there is an inadequate capacity to ensure timely repayment.
D          Obligations which have a high risk of default or which are currently in default.

DESCRIPTION OF THOMSON BANKWATCH'S SHORT-TERM RATINGS
 
TBW-1      The highest category; indicates a very high likelihood that principal and interest
           will be paid on a timely basis.
TBW-2      The second-highest category; while the degree of safety regarding timely repayment
           of principal and interest is strong, the relative degree of safety is not as high
           as for issues rated "TBW-1".
TBW-3      The lowest investment-grade category; indicates that while the obligation is more
           susceptible to adverse developments (both internal and external) than those with
           higher ratings, the capacity to service principal and interest in a timely fashion
           is considered adequate.
TBW-4      The lowest rating category; this rating is regarded as non-investment grade and
           therefore speculative.

                             INVESTMENT LIMITATIONS
 
FUNDAMENTAL POLICIES
 
    The following investment limitations and the investment limitations in the
Prospectus are fundamental policies of the Trust and may not be changed without
shareholder approval.
 
A Fund may not:
 
1.  Issue any class of senior security or sell any senior security of which it
    is the issuer, except that a Fund may borrow from any bank, provided that
    immediately after any such borrowing there is asset coverage of at least
    300% for all borrowings of the Fund, and further provided that, to the
    extent that such borrowings exceed 5% of a Fund's total assets, all
    borrowings shall be repaid before such Fund makes additional investments.
    The term "senior security" shall not include any temporary borrowings that
    do not exceed 5% of the value of such Fund's total assets at the time the
    Fund makes such temporary borrowing. In addition, investment strategies that
    either obligate a Fund to purchase securities or require a Fund to segregate
    assets will not be considered borrowings or senior securities.
 
2.  Make loans if, as a result, more than 33 1/3% of its total assets would be
    lent to other parties, except that each Fund may (i) purchase or hold debt
    instruments in accordance with its investment objective and policies; (ii)
    enter into repurchase agreements; and (iii) lend its securities.
 
3.  Purchase or sell real estate, physical commodities, or commodities
    contracts, except that each Fund may purchase (i) marketable securities
    issued by companies which own or invest in real estate (including real
    estate investment trusts), commodities, or commodities contracts, and (ii)
    commodities contracts relating to financial instruments, such as financial
    futures contracts and options on such contracts.
 
4.  Act as an underwriter of securities of other issuers except as it may be
    deemed an underwriter in selling a portfolio security.
 
5.  Invest in interests in oil, gas or other mineral exploration or development
    programs and oil, gas or mineral leases.
 
NON-FUNDAMENTAL POLICIES
 
    The following investment limitations are non-fundamental policies of the
Trust and may be changed without shareholder approval.
 
A Fund may not:
 
1.  Pledge, mortgage or hypothecate assets except to secure borrowings permitted
    by the Fund's fundamental limitation on borrowing.
 
2.  Invest in companies for the purpose of exercising control.
 
                                      S-15
<PAGE>
3.  Purchase securities on margin or effect short sales, except that each Fund
    may (i) obtain short-term credits as necessary for the clearance of security
    transactions, (ii) provide initial and variation margin payments in
    connection with transactions involving futures contracts and options on such
    contracts, and (iii) make short sales "against the box" or in compliance
    with the SEC's position regarding the asset segregation requirements of
    section 18 of the 1940 Act.
 
   
4.  Invest its assets in securities of any investment company, except as
    permitted by the 1940 Act.
    
 
   
5.  Purchase or hold illiquid securities, I.E., securities that cannot be
    disposed of for their approximate carrying value in seven days or less
    (which term includes repurchase agreements and time deposits maturing in
    more than seven days) if, in the aggregate, more than 15% of its net assets
    would be invested in illiquid securities.
    
 
   
6.  Purchase securities which are not readily marketable if, in the aggregate,
    more than 15% of its total assets would be invested in such securities.
    
 
   
                      THE ADMINISTRATOR AND TRANSFER AGENT
    
 
   
    The Administration Agreement provides that the Administrator, SEI Fund
Management ("SEI Management" or the "Administrator") 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 Administration Agreement relates,
except a loss resulting from willful misfeasance, bad faith or gross negligence
on the part of SEI Management in the performance of its duties or from reckless
disregard of its duties and obligations thereunder.
    
 
   
    The continuance of the Administration Agreement must be specifically
approved at least annually (i) by the vote of a majority of the Trustees or by
the vote of a majority of the outstanding voting securities of the Fund, and
(ii) by the vote of a majority of the Trustees of the Trust who are not parties
to the Administration Agreement or an "interested person" (as that term is
defined in the 1940 Act) of any party thereto, cast in person at a meeting
called for the purpose of voting on such approval. The Administration Agreement
is terminable at any time as to any Fund without penalty by the Trustees of the
Trust, by a vote of a majority of the outstanding shares of the Fund or by SEI
Management on not less than 30 days' nor more than 60 days' written notice. This
Agreement shall not be assignable by either party without the written consent of
the other party.
    
 
   
    The Administrator, a Delaware business trust, has its principal business
offices at Oaks, Pennsylvania 19456. SEI Investments Management Corporation
("SIMC"), a wholly-owned subsidiary of SEI Investments Company ("SEI
Investments"), is the owner of all beneficial interest in the Administrator. SEI
Investments and its subsidiaries and affiliates, including the Administrator,
are leading providers of funds evaluation services, trust accounting systems,
and brokerage and information services to financial institutions, institutional
investors, and money managers. The Administrator and its affiliates also serve
as administrator to the following other mutual funds: The Achievement Funds
Trust, The Advisors' Inner Circle Fund, The Arbor Fund, ARK Funds, Bishop Street
Funds, Boston 1784 Funds-Registered Trademark-, CoreFunds, Inc., CrestFunds,
Inc., CUFUND, The Expedition Funds, FMB Funds, Inc., First American Funds, Inc.,

Asset Allocation Trust, SEI Daily Income Trust, SEI Index Funds, SEI
Institutional Managed Trust, SEI International Trust, SEI Liquid Asset Trust,
SEI Tax Exempt Trust, STI Classic Funds, STI Classic Variable Trust, and TIP
Funds.
    
 
   
    If operating expenses of any Fund exceed applicable limitations, SEI
Management will pay such excess. SEI Management will not be required to bear
expenses of any Fund to an extent which would result in the Fund'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
    
 
                                      S-16

regulations, and generally excludes brokerage commissions, distribution
expenses, taxes, interest and extraordinary expenses.
    
 
   
    For the fiscal year ended May 31, 1997, the Funds paid fees to SEI
Management as follows:

                       THE MANAGER AND THE MONEY MANAGERS
    
 
   
    The Manager Agreement and certain of the Money Manager Agreements provide
that SEI Investments Management Corporation ("SIMC" or the "Manager")(or any
Money Manager) 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. In addition, certain of the Money Manager
Agreements provide that the Money Manager shall not be protected against any
liability to the Trust or its shareholders by reason of willful misfeasance, bad
faith or negligence on its part in the performance of its duties, or from
reckless disregard of its obligations or duties thereunder.
    
 
   
    The continuance of each Manager and Money Manager Agreement must be
specifically approved at least annually (i) by the vote of a majority of the
outstanding shares of that Fund or by the Trustees, and (ii) by the vote of a
majority of the Trustees who are not parties to such Agreement or "interested
persons" of any party thereto, cast in person at a meeting called for the
purpose of voting on such approval. Each Money Manager 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 Fund, by a
majority of the outstanding shares of that Fund, on not less than 30 days' nor
more than 60 days' written notice to the Manager or Money Manager, or by the
Manager or Money Manager on 90 days' written notice to the Trust.
    
 
   
    SIMC and the Trust have obtained an exemptive order from the SEC that
permits SIMC, with the approval of the Trust's Board of Trustees, to retain
unaffiliated Money Managers for a Fund without submitting the Money Manager

                                  DISTRIBUTION
 
    The Distributor, a wholly-owned subsidiary of SEI, and the Trust are parties
to a distribution agreement ("Distribution Agreement"). The Distribution
Agreement shall be reviewed and ratified at least annually (i) by the Trust's
Trustees or by the vote of a majority of the outstanding shares of the Trust,
and (ii) by the vote of a majority of the Trustees of the Trust who are not
parties to the Distribution Agreement or interested persons (as defined in the
1940 Act) of any party to the Distribution Agreement, cast in person at a
meeting called for the purpose of voting on such approval. The Distribution
Agreement will terminate in the event of any assignment, as defined in the 1940
Act, and is terminable with respect to a particular Fund on not less than sixty
days' notice by the Trust's Trustees, by vote of a majority of the outstanding
shares of such Fund or by the Distributor. The Distributor will receive no
compensation for the distribution of Fund shares.
 
   
    Although banking laws and regulations prohibit banks from distributing
shares of open-end investment companies such as the Trust, according to an
opinion issued to the staff of the SEC by the Office of the Comptroller of the
Currency, financial institutions are not prohibited from acting in other
capacities for investment companies, such as providing shareholder services.
Should future legislative, judicial or administrative action prohibit or
restrict the activities of financial institutions in connection with providing
shareholder services, the Trust may be required to alter materially or
discontinue its arrangements with such financial institutions.

                                  PERFORMANCE
 
   
    From time to time, each Fund may advertise yield and/or total return. These
figures will be based on historical earnings and are not intended to indicate
future performance. The yield of a Fund refers to the annualized income
generated by an investment in such Fund over a specified 30-day period. The
yield is calculated by assuming that the income generated by the investment
during that period generated each period over one year and is shown as a
percentage of the investment. In particular, yield will be calculated according
to the following formula:
    
 
       Yield = 2[(((a-b)/cd) + 1)(6)-1], where a = dividends and interest
       earned during the period; b = expenses accrued for the period (net
       of reimbursement); c = the current daily number of shares
       outstanding during the period that were entitled to receive
       dividends; and d = the maximum offering price per share on the
       last day of the period.
 
   
    Actual yield will depend on such variables as asset quality, average asset
maturity, the type of instruments a Fund invests in, changes in interest rates
on money market instruments, changes in the expenses of the Fund and other
factors. For the 30-day period ending May 31, 1997, the yields for the Large
Cap, Small Cap and Core Fixed Income Funds were 1.58%, 0.82% and 6.43%,
respectively.
    
 
    The total return of a Fund refers to the average compounded rate of return
to a hypothetical investment for designated time periods (including, but not
limited to, the period from which the Fund commenced operations through the
specified date), assuming that the entire investment is redeemed at the end of
each period. In particular, total return will be calculated according to the
following formula:
 
       P(1 + T)(n) = ERV, where P = a hypothetical initial payment of
       $1,000; T = average annual total return; n = number of years; and
       ERV = ending redeemable value of a hypothetical $1,000 payment
       made at the beginning of the designated time period as of the end
       of such period.

    The Funds may, from time to time, compare their performance to other mutual
funds tracked by mutual fund rating services, to broad groups of comparable
mutual funds or to unmanaged indices which may assume investment of dividends
but generally do not reflect deductions for administrative and management costs.
 
    From time to time the Trust may include the names of clients of the Money
Managers in advertisements and/or sales literature for the Trust.
 
                       PURCHASE AND REDEMPTION OF SHARES
 
   
    The purchase and redemption price of shares is the net asset value of each
share. A Fund's securities are valued by SEI Management pursuant to valuations
provided by an independent pricing service (generally the last quoted sale
price). Fund securities listed on a securities exchange for which market
quotations are available are valued at the last quoted sale price on each
Business Day (defined as days on which the New York Stock Exchange is open for
business ("Business Day")) or, if there is no such reported sale, at the most
recently quoted bid price. Unlisted securities for which market quotations are
readily available are valued at the most recently quoted bid price. The pricing
service may also use a matrix system to determine valuations. This system
considers such factors as security prices, yields, maturities, call features,
ratings and developments relating to specific securities in arriving at
valuations. The procedures of the pricing service and its valuations are
reviewed by the officers of the Trust under the general supervision of the
Trustees.
    
 
    It is currently the Trust's policy to pay all redemptions in cash. The Trust
retains the right, however, to alter this policy to provide for redemptions in
whole or in part by a distribution in kind of readily marketable securities held
by a Fund in lieu of cash. Shareholders may incur brokerage charges on the sale
of any such securities so received in payment of redemptions. However, a
shareholder will at all times be entitled to aggregate cash redemptions from all
Funds of the Trust during any 90-day period of up to the lesser of $250,000 or
1% of the Trust's net assets.
 
    A gain or loss for federal income tax purposes may be realized by a taxable
shareholder upon an in-kind redemption depending upon the shareholder's basis in
the shares of the Trust redeemed.
 
   
    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 fund securities is not reasonably practicable, or
for such other periods as the SEC may by order permit. The Trust also reserves
the right to suspend sales of shares of the Funds for any period during which
the New York Stock Exchange, the Manager, the Administrator, the Distributor,
the Money Managers and/or the Custodian are not open for business. Currently,
the following

holidays are observed by the Trust: New Year's Day, Martin Luther King, Jr. Day,
Presidents' Day, Good Friday, Memorial Day, Independence Day, Labor Day,
Thanksgiving Day and Christmas Day.
    
 
   
    The securities may be traded on foreign markets on days other than Business
Days or the net asset value of a Fund may be computed on days when such foreign
markets are closed. In addition, foreign markets may close at times other than
4:00 p.m. Eastern time. As a consequence, the net asset value of a share of a
Fund may not reflect all events that may affect the value of the Fund's foreign
securities unless the Money Managers determine that such events materially
affect net asset value in which case net asset value will be determined by
consideration of other factors.
    
 
                                     TAXES
 
    The following is only a summary of certain additional federal tax
considerations generally affecting the Funds and their shareholders that are not
described in the Funds' Prospectus. No attempt is made to present a detailed
explanation of the federal, state or local tax treatment of the Funds or their
shareholders and the discussion here and in the Funds' Prospectus is not
intended as a substitute for careful tax planning.
 
    This discussion of federal income tax consequences is based on 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 Fund is treated as a separate entity for federal income tax purposes
and is not combined with the Trust's other Funds. Each Fund intends to qualify
as a regulated investment company ("RIC") under Subchapter M of the Code so that
it will be relieved of federal income tax on that part of its income that is
distributed to shareholders. In order to qualify for treatment as a RIC, a Fund
must distribute annually to its shareholders at least 90% of its investment
company taxable income (generally, net investment income plus the excess, if
any, of net short-term capital gain over net long-term capital losses)
("Distribution Requirement") and also must meet several additional requirements.
Among these requirements are the following: (i) at least 90% of a Fund'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, securities or foreign currencies, or other income derived with respect to
its business of investing in such stock or securities or currencies; (ii) at the
close of each quarter of a Fund'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 RICs 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 Fund's assets and that does not represent more than
10% of the outstanding voting securities of such issuer; and (iii) at the close
of each quarter of a Fund'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 RICs) of any one issuer or of two or more issuers which
the Fund controls and which are engaged in the same, similar, or related trades
or businesses.
    
 
    Notwithstanding the Distribution Requirement described above, which only
requires a Fund to distribute at least 90% of its annual investment company
taxable income and does not require any minimum distribution of net capital
gain, a Fund 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 gain over short- and long-term capital
loss) for the one-year period ending on October 31 of that year, plus certain
other amounts. Each Fund intends to make sufficient distributions to avoid
liability for the federal excise tax. A Fund may in certain circumstances be
required to liquidate Fund investments in order to make sufficient distributions
to avoid federal excise tax liability at a time when the investment advisor
might not otherwise have chosen to do so, and liquidation of investments in such
circumstances may affect the ability of a Fund to satisfy the requirements for
qualification as a RIC.
 
                                      S-23
<PAGE>
   
    Any gain or loss recognized on a sale, exchange or redemption of shares of a
Fund by a shareholder who is not a dealer in securities will generally, for
individual shareholders, be treated as a long-term capital gain or loss if the
shares have been held for more than eighteen months, mid-term capital gain if
the shares are held for more than twelve but not more than eighteen months, and
otherwise will be treated as a short-term capital gain or loss. However, if
shares on which a shareholder has received a net capital gain distribution are
subsequently sold, exchanged or redeemed and such shares have been held for six
months or less, any loss recognized will be treated as a long-term capital loss
to the extent of the net capital gain distribution.
    
 
   
    Long-term capital gains are currently taxed at a maximum rate of 20%,
mid-term capital gains are currently taxed at a maximum rate of 28%, and
short-term capital gains are currently taxed at ordinary income tax rates.
    
 
    If a Fund fails to qualify as a RIC for any year, all of its income will be
subject to federal income tax at corporate rates, and its distributions
(including capital gain distributions) generally will be taxable as ordinary
income dividends to its shareholders, subject to the dividends received
deduction for eligible corporate shareholders.
 
    A Fund will be required in certain cases to withhold and remit to the United
States Treasury 31% of amounts payable to any shareholder who (1) has provided
the Fund either an incorrect tax identification number or no number at all, (2)
who is subject to backup withholding by the Internal Revenue Service for failure
to properly report payments of interest or dividends, or (3) who has failed to
certify to the Fund that such shareholder is not subject to backup withholding.
 
    Dividends and interest received by a Fund may be subject to income,
withholding or other taxes imposed by foreign countries and United States
possessions that would reduce the yield on a Fund's securities. Tax conventions
between certain countries and the United States may reduce or eliminate these
taxes. Foreign countries generally do not impose taxes on capital gains with
respect to investments by foreign investors. If more than 50% of the value of a
Fund's total assets at the close of its taxable year consists of securities of
foreign corporations, a Fund will be eligible to, and will, file an election
with the Internal Revenue Service that will enable shareholders, in effect, to
receive the benefit of the foreign tax credit with respect to any foreign and
United States possessions income taxes paid by a Fund. Pursuant to the election,
a Fund will treat those taxes as dividends paid to its shareholders. Each
shareholder will be required to include a proportionate share of those taxes in
gross income as income received from a foreign source and must treat the amount
so included as if the shareholder had paid the foreign tax directly. The
shareholder may then either deduct the taxes deemed paid by him or her in
computing his or her taxable income or, alternatively, use the foregoing
information in calculating the foreign tax credit (subject to significant
limitations) against the shareholder's federal income tax. If a Fund makes the
election, it will report annually to its shareholders the respective amounts per
share of the Fund's income from sources within, and taxes paid to, foreign
countries and United States possessions.
 
STATE TAXES
 
    A Fund is not liable for any income or franchise tax in Massachusetts if it
qualifies as a RIC for federal income tax purposes. Distributions by a Fund to
shareholders and the ownership of shares may be subject to state and local
taxes. Shareholders should consult their own tax advisers regarding the affect
of federal, state and local taxes in their own individual circumstances.
 
   
                             PORTFOLIO TRANSACTIONS
    
 
    Money Managers make decisions to buy or sell securities independently from
one another. Thus, one Money Manager could sell a security at approximately the
same time another Money Manager for the same Fund is purchasing the same type of
security. In addition, when a Money Manager's services are
 
                                      S-24
<PAGE>
terminated and/or a new Money Manager is retained, the new Money Manager may
significantly restructure the Fund's portfolio. These practices may increase the
Funds' portfolio turnover rates, realization of gains or losses, brokerage
commissions and other transaction based costs.
 
    The Trust has no obligation to deal with any dealer or group of dealers in
the execution of transactions in fund securities. Subject to policies
established by the Trustees, the Money Managers are responsible for placing
orders to execute Fund 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 Money
Managers generally seek reasonably competitive spreads or commissions, the Trust
will not necessarily be paying the lowest spread or commission available. The
Trust will not purchase fund securities from any affiliated person acting as
principal except in conformity with the regulations of the SEC.
 
    The money market securities in which a Fund invests are traded primarily in
the over-the-counter market. Bonds and debentures are usually traded
over-the-counter, but may be traded on an exchange. Where possible, the Money
Managers will deal directly with the dealers who make a market in the securities
involved except in those circumstances where better prices and execution are
available elsewhere. Such dealers usually are acting as principal for their own
account. On occasion, securities may be purchased directly from the issuer.
Money market securities are generally traded on a net basis and do not normally
involve either brokerage commissions or transfer taxes. The cost of executing
fund securities transactions of a Fund will primarily consist of dealer spreads
and underwriting commissions.
 
    It is expected that the Funds may execute brokerage or other agency
transactions through the Distributor, a registered broker-dealer, for a
commission, in conformity with the 1940 Act, the Securities Exchange Act of
1934, as amended, and rules of the SEC. Under these provisions, the Distributor
is permitted to receive and retain compensation for effecting fund transactions
for a Fund on an exchange. These provisions further require that commissions
paid to the Distributor by the Trust for exchange transactions not exceed "usual
and customary" brokerage commissions. The rules define "usual and customary"
commissions to include amounts which are "reasonable and fair compared to the
commission, fee or other remuneration received or to be received by other
brokers in connection with comparable transactions involving similar securities
being purchased or sold on a securities exchange during a comparable period of
time." In addition, a Fund may direct commission business to one or more
designated broker-dealers, including the Distributor, in connection with such
broker-dealer's payment of certain of the Fund's expenses. The Trustees,
including those who are not "interested persons" of the Trust, have adopted
procedures for evaluating the reasonableness of commissions paid to the
Distributor and will review these procedures periodically.
 
    Since the Trust does not market its shares through intermediary brokers or
dealers, it is not the Trust's practice to allocate brokerage or principal
business on the basis of sales of its shares which may be made through such
firms. However, the Fund's Money Managers may place fund orders with qualified
broker-dealers who recommend the Trust to clients, and may, when a number of
brokers and dealers can provide best price and execution on a particular
transaction, consider such recommendations by a broker or dealer in selecting
among broker-dealers.
 
    The Trust does not expect to use one particular dealer, but a Fund's Money
Managers may, consistent with the interests of the Fund, select brokers on the
basis of the research services they provide to the Fund's Money Managers. Such
services may include analysis of the business or prospects of a company,
industry or economic sector or statistical and pricing services. Information so
received by the Money Manager will be in addition to and not in lieu of the
services required to be performed by a Fund's Money Managers under the Advisory
and/or Sub-Advisory Agreements. If in the judgement of a Fund's Money Managers
the Funds, or other accounts managed by the Fund's Money Managers, will be
benefitted by supplemental research services, the Fund's Money Managers are
authorized to pay brokerage commissions to a broker furnishing such services
which are in excess of commissions which another broker may have
 
                                      S-25
<PAGE>
charged for effecting the same transaction. The expenses of a Fund's Money
Managers will not necessarily be reduced as a result of the receipt of such
supplemental information.
 
   
    In connection with transactions effected for Funds operating within the
"Manager of Managers" structure, under this policy, SIMC and the various firms
that serve as money managers to certain Funds of the Trust, in the exercise of
joint investment discretion over the assets of a Fund, may direct a portion of a
Fund's brokerage to the Distributor. All such transactions directed to the
Distributor must be accomplished in a manner that is consistent with the Trust's
policy to achieve best net results, and must comply with the Trust's procedures
regarding the execution of transactions through affiliated brokers.
    
 
   
    For the fiscal year ended May 31, 1997, the Funds paid the following
brokerage fees:

                             DESCRIPTION OF SHARES
 
    The Declaration of Trust authorizes the issuance of an unlimited number of
shares of each Fund, each of which represents an equal proportionate interest in
that Fund. Each share upon liquidation entitles a shareholder to a pro rata
share in the net assets of that Fund. Shareholders have no preemptive rights.
The
 
                                      S-26
<PAGE>
Declaration of Trust provides that the Trustees of the Trust may create
additional series of shares or separate classes of funds. 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 or her 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 or her willful misfeasance, bad faith, gross negligence or reckless
disregard of his or her duties.
 
                                     VOTING
 
    Where the Prospectus for the Funds or this Statement of Additional
Information state that an investment limitation or a fundamental policy may not
be changed without shareholder approval, such approval means the vote of (i) 67%
or more of the Fund's shares present at a meeting if the holders of more than
50% of the outstanding shares of the Fund are present or represented by Proxy,
or (ii) more than 50% of the Fund's outstanding shares, whichever is less.
 
                             SHAREHOLDER LIABILITY
 
    The Trust is an entity of the type commonly known as a "Massachusetts
business trust." Under Massachusetts law, shareholders of such a Trust could,
under certain circumstances, be held personally liable as partners for the
obligations of the Trust. Even if, however, the Trust were held to be a
partnership, the possibility of the shareholders' incurring financial loss for
that reason appears remote because the Trust's Declaration of Trust (i) contains
an express disclaimer of shareholder liability for obligations of the Trust and
requires that notice of such disclaimer be given in each agreement, obligation
or instrument entered into or executed by or on behalf of the Trust or the
Trustees, and (ii) provides for indemnification out of the Trust property for
any shareholders held personally liable for the obligations of the Trust.

ITEM 27.  INDEMNIFICATION:
 
    Article VIII of the Agreement and Declaration of Trust is filed as Exhibit 1
to the Registration Statement. Insofar as indemnification for liabilities
arising under the 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, suite 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.

                            INVESTMENT ADVISORY AGREEMENT
                         SEI INSTITUTIONAL INVESTMENTS TRUST

    AGREEMENT made this 14th day of June, 1996, by and between SEI
Institutional Investments Trust, a Massachusetts business trust (the "Trust"),
and SEI Financial Management Corporation, (the "Adviser").

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

    WHEREAS, the Trust desires to retain the Adviser to render investment
management services with respect to its Large Cap, Small Cap, Core Fixed Income,
High Yield Bond, International Fixed Income, Emerging Markets Equity and
International Equity Funds and such other portfolios as the Trust and the
Adviser may agree upon (the "Portfolios"), and the Adviser is willing to render
such services:

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

1.  DUTIES OF THE ADVISER. The Trust employs the Adviser to manage the
    investment and reinvestment of the assets, to hire (subject to the approval
    of the Trust's Board of Trustees and, except as otherwise permitted under
    the terms of any exemptive relief obtained by the Adviser from the
    Securities and Exchange Commission, or by rule or regulation, a majority of
    the outstanding voting securities of any affected Portfolio(s)) and
    thereafter supervise the investment activities of one or more sub-advisers
    deemed necessary to carry out the investment program of any Portfolios of
    the Trust, and to continuously review, supervise and (where appropriate)
    administer the investment program of the Portfolios, to determine in its
    discretion (where appropriate) the securities to be purchased or sold, to
    provide the Administrator and the Trust with records concerning the
    Adviser's activities which the Trust is required to maintain, and to render
    regular reports to the Administrator and to the Trust's officers and
    Trustees concerning the Adviser's discharge of the foregoing
    responsibilities. The retention of a sub-adviser by the Adviser shall not
    relieve the Adviser of its responsibilities under this Agreement.

    The Adviser shall discharge the foregoing responsibilities subject to the
    control of the Board of 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 and statement of additional information, as
    amended from time to time (referred to collectively as the "Prospectus"),
    and applicable laws and regulations. The Trust will furnish the Adviser
    from time to time with copies of all amendments or supplements to the
    Prospectus, if any.

    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 (including any sub-advisers) required by it to
    perform the services on the terms and for the compensation provided herein.
    The Adviser will not, however, pay for the cost of securities, commodities,
    and other investments (including brokerage commissions and other
    transaction charges, if any) purchased or sold for the Trust.


2.  DELIVERY OF DOCUMENTS. The Trust has furnished Adviser with copies properly
    certified or authenticated of each of the following:


                                          1
<PAGE>

    (a)  The Trust's Agreement and Declaration of Trust, as filed with the
    Secretary of State of the Commonwealth of Massachusetts (such Agreement and
    Declaration of Trust, as presently in effect and as it shall from time to
    time be amended, is herein called the "Declaration of Trust");

    (b)  By-Laws of the Trust (such By-Laws, as in effect on the date of this
    Agreement and as amended from time to time, are herein called the
    "By-Laws");

    (c)  Prospectus(es) of the Portfolio(s).

3.  OTHER COVENANTS. The Adviser agrees that it:

    (a)  will comply with all applicable Rules and Regulations of the
    Securities and Exchange Commission and will in addition conduct its
    activities under this Agreement in accordance with other applicable law;

    (b)  will place orders pursuant to its investment determinations for the
    Portfolios either directly with the issuer or with any broker or dealer. In
    executing Portfolio transactions and selecting brokers or dealers, the
    Adviser will use its best efforts to seek on behalf of the Portfolio the
    best overall terms available. In assessing the best overall terms available
    for any transaction, the Adviser shall consider all factors that it deems
    relevant, including the breadth of the market in the security, the price of
    the security, the financial condition and execution capability of the
    broker or dealer, and the reasonableness of the commission, if any, both
    for the specific transaction and on a continuing basis. In evaluating the
    best overall terms available, and in selecting the broker-dealer to execute
    a particular transaction the Adviser may also consider the brokerage and
    research services (as those terms are defined in Section 28(e) of the
    Securities Exchange Act of 1934) provided to the Portfolio and/or other
    accounts over which the Adviser or an affiliate of the Adviser may exercise
    investment discretion. The Adviser is authorized, subject to the prior
    approval of the Trust's Board of Trustees, to pay to a broker or dealer who
    provides such brokerage and research services a commission for executing a
    portfolio transaction for any of the Portfolios which is in excess of the
    amount of commission another broker or dealer would have charged for
    effecting that transaction if, but only if, the Adviser determines in good
    faith that such commission was reasonable in relation to the value of the
    brokerage and research services provided by such broker or dealer - -
    viewed in terms of that particular transaction or terms of the overall
    responsibilities of the Adviser to the Portfolio. In addition, the Adviser
    if authorized to allocate purchase and sale orders for portfolio securities
    to brokers or dealers (including brokers and dealers that are affiliated
    with the Adviser or the Trust's principal underwriter) to take into
    account the sale of shares of the Trust if the Adviser believes that the
    quality of the transaction and the commission are comparable to what they
    would be with other qualified firms. In no instance, however, will any
    Portfolio's securities be purchased from or sold to the Adviser, any
    sub-adviser engaged with respect to that Portfolio, the Trust's principal
    underwriter, or any affiliated person of either the Trust, the Adviser, and
    sub-adviser or the principal underwriter, acting as principal in the
    transaction, except to the extent permitted by the Securities and Exchange
    Commission and the 1940 Act.

4.  COMPENSATION OF THE ADVISER. 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 compensation at the rate(s) specified in the Schedule(s) which
    are attached hereto and made a part of this Agreement. Such compensation
    shall be paid to the Adviser at the end of each month, and calculated by
    applying a 


                                          2
<PAGE>


    daily rate, based on the annual percentage rates as specified in the
    attached Schedule(s), to the assets of the Portfolio. The fee shall be
    based on the average daily net assets for the month involved. The Adviser
    may, in its discretion and from time to time, waive a portion of its fee.

    All rights of compensation under this Agreement for services performed as
    of the termination date shall survive the termination of this Agreement.

5.  EXCESS EXPENSES. If the expenses for any Portfolio for any fiscal year
    (including fees and other amounts payable to the Adviser, but excluding
    interest, taxes, brokerage costs, litigation, and other extraordinary
    costs) as calculated every business day would exceed the expense
    limitations imposed on investment companies by any applicable statute or
    regulatory authority of any jurisdiction in which Shares are qualified for
    offer and sale, the Adviser shall bear such excess cost. 

    However, the Adviser will not bear expenses of the Trust or any Portfolio
    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 Adviser pursuant to this Section 5 shall be settled on a
    monthly basis (subject to fiscal year end reconciliation) by a waiver of
    the Adviser's fees provided for hereunder, and such waiver shall be treated
    as a reduction in the purchase price of the Adviser's services. 

6.  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. The Adviser further agrees to furnish to the Trust, if applicable,
    the same such documents and information pertaining to any sub-adviser as
    the Trust may reasonably request.

7.  STATUS OF THE 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. To the extent that the purchase or sale of securities
    or other investments of any issuer may be deemed by the Adviser to be
    suitable for two or more accounts managed by the Adviser, the available
    securities or investments may be allocated in a manner believed by the
    Adviser to be equitable to each account. It is recognized that in some
    cases this may adversely affect the price paid or received by the Trust or
    the size or position obtainable for or disposed by the Trust or any
    Portfolio.

8.  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 1940 Act which are prepared or maintained by the Adviser (or any
    sub-adviser) on behalf of the Trust are the property of the Trust and will
    be surrendered promptly to the Trust on request. The Adviser further agrees
    to preserve for the periods prescribed in Rule 31a-2 under the 1940 Act
    the records required to be maintained under Rule 31a-1 under the 1940 Act.

9.  LIMITATION OF LIABILITY OF THE ADVISER. The duties of the Adviser shall be
    confined to those expressly set forth herein, and no implied duties are
    assumed by or may be asserted against the Adviser hereunder. The Adviser
    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


                                          3
<PAGE>

    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 Section 9, the term "Adviser" shall
    include directors, officers, employees and other corporate agents of the
    Adviser as well as that corporation itself).

10. 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, officers, shareholders or otherwise;
    and the Adviser (or any successor) is or may be interested in the Trust as
    a shareholder or otherwise subject to the provisions of applicable law. All
    such interests shall be fully disclosed between the parties on an ongoing
    basis and in the Trust's Prospectus as required by law. In addition,
    brokerage transactions for the Trust may be effected through affiliates of
    the Adviser or any sub-adviser if approved by the Board of Trustees,
    subject to the rules and regulations of the Securities and Exchange
    Commission.

11. DURATION AND TERMINATION. This Agreement, unless sooner terminated as
    provided herein, shall remain in effect until two years from date of
    execution, 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 1940 Act and rules and regulations thereunder.
    The foregoing requirement that continuance of this Agreement be
    "specifically approved at least annually" shall be construed in a manner
    consistent with the 1940 Act 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.

    As used in this Section 11, 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 1940 Act and the rules and
    regulations thereunder, subject to such exemptions as may be granted by the
    Securities and Exchange Commission. 

12. GOVERNING LAW. This Agreement shall be governed by the internal laws of the
    Commonwealth of Massachusetts, without regard to conflict of law
    principles; provided, however that nothing herein shall be construed as
    being inconsistent with the 1940 Act. 

13. NOTICE: Any notice, advice or report to be given pursuant to this Agreement
    shall be deemed sufficient if delivered or mailed by registered, certified
    or overnight mail, postage prepaid addressed by the party giving notice to
    the other party at the last address furnished by the other party:

14. 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. 

15. ENTIRE AGREEMENT. This Agreement embodies the entire agreement and
    understanding between the parties hereto, and supersedes all prior
    agreements and understandings relating to this Agreement's subject matter.
    This Agreement may be executed in any number of counterparts, each of which
    shall be deemed to be an original, but such counterparts shall, together,
    constitute only one instrument.

A copy of the Declaration of Trust of the Trust is on file with the Secretary of
State 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
is 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.

No Portfolio of the Trust shall be liable for the obligations of any other
Portfolio of the Trust. Without limiting the generality of the foregoing, the
Adviser shall look only to the assets of a particular Portfolio for payment of
fees for services rendered to that Portfolio.

Where the effect of a requirement of the 1940 Act reflected in any provision of
this Agreement is altered by a rule, regulation or order of the Commission,
whether of special or general application, such provision shall be deemed to
incorporate the effect of such rule, regulation or order.


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

subject to the provisions of Section 7.3, each shareholder shall be entitled 
to a certificate stating the number of shares owned by him or her, in such 
form as shall be prescribed from time to time by the Trustees.  Such

shareholder services agent may either issue receipts therefor or may keep
accounts upon the books of the Trust for the record holders of such shares, who
shall in either case be deemed, for all purposes hereunder, to be the holders of
certificates for such shares as if they had accepted such certificates and shall
be held to have expressly assented and agreed to the terms hereof.

or the mutilation of a share certificate, a duplicate certificate may be issued
in place thereof, upon such terms as the Trustees may prescribe.

time discontinue the issuance of share certificates and may, by written 
notice to each shareholder, require the surrender of share certificates to 
the Trust for cancellation.  Such surrender and cancellation shall not affect 
the ownership of shares in the Trust.

                       SECTION 8.     RECORD DATE

The Trustees may fix in advance a time, which shall not be more than 60 days
before the date of any meeting of shareholders or the date for the payment of
any dividend or making of any other distribution to shareholders, as the record
date for determining the shareholders having the right to notice and to vote at
such meeting and any adjournment thereof or the right to receive such dividend
or distribution, and in such case only shareholders of record on such record
date shall have such right, notwithstanding any transfer of shares on the books
of the Trust after the record date.

presidents or by the treasurer or by whomsoever else shall be designated for
that purpose by the vote of the Trustees and need not bear the seal of the

         equivalent to orders received by the distributor;

         (b)  shares of the Trust may be purchased at not less than net asset 
         value for investment by the investment advisor and by officers and

by the Trust in a system for the central handling of securities operated by 
the Federal Reserve Banks, or established by a national securities exchange 
or national securities association registered with said Commission under the

said Commission, pursuant to which system all securities of any particular 
class or series of any issue deposited with the system are treated as 
fungible and may be transferred or pledged by bookkeeping entry, without 
physical delivery of such securities.

The Trust shall upon the resignation or inability to serve of its custodian or
upon change of the custodian:

condition of the Trust and of the results of its operation, containing all

                        INVESTMENT SUB-ADVISORY AGREEMENT
                       SEI INSTITUTIONAL INVESTMENTS TRUST

     AGREEMENT made this 14th day of June, 1996, by and among SEI Financial
Management Corporation, (the "Adviser") and 1838 Investment Advisors, L.P. (the
"Sub-Adviser").

     WHEREAS, SEI Institutional Investments Trust, a Massachusetts business
trust (the "Trust") is registered as an open-end management investment company
under the Investment Company Act of 1940, as amended (the "1940 Act"); and

     WHEREAS, the Adviser has entered into an Investment Advisory Agreement 
dated June 14, 1996 (the "Advisory Agreement") with the Trust, pursuant to 
which the Adviser will act as investment adviser to the Small Cap Portfolio 
(the "Portfolio"), which is a series of the Trust; and

     WHEREAS, the Adviser, with the approval of the Trust, desires to retain the
Sub-Adviser to provide investment advisory services to the Adviser in connection
with the management of the Portfolio, and the Sub-Adviser is willing to render
such investment advisory services.

     NOW, THEREFORE, the parties hereto agree as follows:

1.   DUTIES OF THE SUB-ADVISER. Subject to supervision by the Adviser and the
     Trust's Board of Trustees, the Sub-Adviser shall manage the investment
     operations of the Portfolio and the composition of the Portfolio, including
     the purchase, retention and disposition of securities and other assets, in
     accordance with the Portfolio's investment objectives, policies and
     restrictions as stated in the Portfolio's prospectus and statement of
     additional information, as currently in effect and as amended or
     supplemented from time to time (referred to collectively as the
     "Prospectus"), and subject to the following:

(a)  The Sub-Adviser shall provide supervision of the Portfolio's investments
     and determine from time to time what investments and securities will be
     purchased, retained or sold by the Portfolio, and what portion of the
     assets will be invested or held uninvested in cash.

(b)  In the performance of its duties and obligations under this Agreement, the
     Sub-Adviser shall act in conformity with the Trust's Declaration of Trust
     (as defined herein) and the Prospectus and with the instructions and
     directions of the Adviser and of the Board of Trustees of the Trust and
     will conform to and comply with the requirements of the 1940 Act, the
     Internal Revenue Code of 1986, and all other applicable federal and state
     laws and regulations, as each is amended from time to time.

(c)  The Sub-Adviser shall determine the securities to be purchased or sold by
     the Portfolio and will place orders with or through such persons, brokers
     or dealers to carry out the policy with respect to brokerage set forth in
     the Portfolio's Registration Statement (as defined herein) and Prospectus
     or as the Board of Trustees or the Adviser may direct from time to time, in
     conformity with federal securities laws. In executing Portfolio
     transactions and selecting brokers or dealers, the Sub-Adviser will use its
     best efforts to seek on behalf of the Portfolio the best overall terms
     available. In assessing the best overall terms available for any
     transaction, the Sub-Adviser shall consider all factors that it deems
     relevant, including the breadth of the market in the security, the price of
     the security, the financial condition and execution capability of the
     broker or dealer, and the reasonableness of the commission, if any, both
     for the specific transaction and on a continuing basis. In evaluating the
     best overall terms available, and in selecting the broker-dealer to execute
     a particular transaction the Sub-Adviser may also consider the brokerage
     and research services (as those terms are defined in Section 28(e) of the
     Securities Exchange Act of 1934) provided to the Portfolio and/or other
     accounts over which the Sub-Adviser or an affiliate of the Sub-Adviser may
     exercise investment discretion. The Sub-Adviser is authorized, subject to
     the prior approval of the Trust's Board of Trustees, to pay to a broker or
     dealer who provides such brokerage and research services a commission for
     executing a portfolio transaction for any of the Portfolios which is in
     excess of the amount of commission another broker or dealer would have
     charged for effecting that transaction if, but only if, the Sub-Adviser
     determines in good faith that such commission was reasonable in relation to
     the value of the brokerage and research services provided by such broker or
     dealer -- viewed in terms of that particular transaction or terms of the
     overall responsibilities of the Sub-Adviser

<PAGE>

     provided to the Portfolio and/or other accounts over which the Sub-Adviser
     or an affiliate of the Sub-Adviser may exercise investment discretion. The
     Sub-Adviser is authorized, subject to the prior approval of the Trust's
     Board of Trustees, to pay to a broker or dealer who provides such brokerage
     and research services a commission for executing a portfolio transaction
     for any of the Portfolios which is in excess of the amount of commission
     another broker or dealer would have charged for effecting that transaction
     if, but only if, the Sub-Adviser determines in good faith that such
     commission was reasonable in relation to the value of the brokerage and
     research services provided by such broker or dealer - - viewed in terms of
     that particular transaction or terms of the overall responsibilities of the
     Sub-Adviser to the Portfolio. In addition, the Sub-Adviser if authorized to
     allocate purchase and sale orders for portfolio securities to brokers or
     dealers (including brokers and dealers that are affiliated with the
     Sub-Adviser or the Trust's principal underwriter) to take into account the
     sale of shares of the Trust if the Sub-Adviser believes that the quality of
     the transaction and the commission are comparable to what they
     would be with other qualified firms. In no instance, however, will any
     Portfolio's securities be purchased from or sold to the Sub-Adviser, the
     Trust's principal underwriter, or any affiliated person of either the 
     Trust, the Sub-Adviser or the principal underwriter, acting as principal 
     in the transaction. except to the extent permitted by the Securities and

     may, in its discretion and from time to time, waive a portion of its fee.

5.   LIMITATION OF LIABILITY OF THE SUB-ADVISER. The Sub-Adviser shall not be
     liable for any error of judgment or for any loss suffered by the Adviser in
     connection with performance of its obligations under this Agreement, except

     receipt of compensation for services (in which case any award of damages
     shall be limited to the period and the amount set forth in Section 36(b)(3)
     of the 1940 Act), or a loss resulting from willful misfeasance, bad faith
     or negligence on the Sub-Adviser's part in the performance of its duties or
     from reckless disregard of its obligations and duties under this Agreement,
     except as may otherwise be provided under provisions of applicable state
     law which cannot be waived or modified hereby.

6.   REPORTS. During the term of this Agreement, the Adviser agrees to furnish
     the Sub-Adviser at its principal office all prospectuses, proxy statements,
     reports to stockholders, sales literature or other materials prepared for
     distribution to stockholders of the Portfolios, the Trust or the public

     agreed) after receipt thereof. The Sub-Adviser's right to object to such
     materials is limited to the portions of such materials that expressly 
     relate to the Sub-Adviser, its services and its clients. The Adviser agrees
     to use its reasonable best efforts to ensure that materials prepared by its
     employees or agents or its affiliates that refer to the Sub-Adviser or its
     clients in any way are consistent with those materials previously approved
     by the Sub-Adviser as referenced in the first sentence of this paragraph.

     performance by the Sub-Adviser of its duties hereunder, provided, however,
     that the Sub-Adviser shall not be required to indemnify or otherwise hold
     the Adviser harmless under this Section 8 where the claim against, or the
     loss, liability or damage experienced by the Adviser, is caused by or is
     otherwise directly related to the Adviser's own willful misfeasance, bad
     faith or negligence, or to the reckless disregard of its duties under this
     Agreement.

9.   DURATION AND TERMINATION. This Agreement shall become effective upon its
     approval by the Trust's Board of Trustees and by the vote of a majority of
     the outstanding voting securities of the Portfolio; provided, however, that
     at any time the Adviser shall have obtained exemptive relief from the SEC
     permitting it to engage a Sub-Adviser without first obtaining approval of
     the Agreement from a majority of the outstanding voting securities of the
     Portfolio(s) involved, the Agreement shall become effective upon its
     approval by the Trust's Board of Trustees. Any Sub-Adviser so selected and
     approved shall be without the protection accorded by shareholder approval
     of an investment adviser's receipt of compensation under Section 36(b) of

     event of a termination of the Adviser's agreement with the Trust. As used
     in this Section 9, the terms "assignment" and "vote of a majority of the
     outstanding voting securities" shall have the respective meanings set forth
     in the 1940 Act and the rules and regulations thereunder, subject to such
     exceptions as may be granted by the Commission under the 1940 Act.

10.  GOVERNING LAW. This Agreement shall be governed by the internal laws of the

     principles; provided, however, that nothing herein shall be construed as
     being inconsistent with the 1940 Act.

11.  SEVERABILITY. Should any part of this Agreement be held invalid by a court 
     decision, statute, rule or otherwise, the remainder of this Agreement shall
     not be affected thereby. This Agreement shall be binding upon and shall

                         SEI INSTITUTIONAL INVESTMENTS TRUST

    AGREEMENT made this 14th day of June 1996, by and among SEI Financial 
Management Corporation, (the "Adviser") and Acadian Asset Management, Inc. 
(the "Sub-Adviser")

    WHEREAS, SEI Institutional Investments Trust, a Massachusetts business 
trust (the "Trust") is registered as an open-end management investment 
company under the Investment Company Act of 1940, as amended (the "1940 
Act"); and

    WHEREAS, the Adviser has entered into an Investment Advisory Agreement 
dated June 14, 1996 (the "Advisory Agreement") with the Trust, pursuant to 
which the Adviser will act as investment adviser to the International Equity 
Portfolio (the "Portfolio"), which is a series of the Trust; and

    WHEREAS, the Adviser, with the approval of the Trust, desires to retain 
the Sub-Adviser to provide investment advisory services to the Adviser in 
connection with the management of the Portfolio, and the Sub-Advisor is 
willing to render such investment advisory services.

NOW, THEREFORE, the parties hereto agree as follows:

1   DUTIES OF THE SUB-ADVISER. Subject to supervision by the Adviser and the  
   Trust's Board of Trustees, the Sub-Adviser shall manage the investment     
operations of the Portfolio and the composition of the Portfolio, including   
  the purchase, retention and disposition of securities and other assets, in  
   accordance with the Portfolio's investment objectives, policies and     
restrictions as stated in the Portfolio's prospectus and statement of     
additional information, as currently in effect and as amended or     
supplemented from time to time (referred to collectively as the     
"Prospectus"), and subject to the following.

(a) The Sub-Adviser shall provide supervision of the Portfolio's investments
    and determine from time to time what investments and securities will be
    purchased, retained or sold by the Portfolio, and what portion of the
    assets will be invested or held uninvested in cash.

(b) In the performance of its duties and obligations under this Agreement, the
    Sub-Adviser shall act in conformity with the Trust's Declaration of Trust
    (as defined herein) and the Prospectus and with the instructions and
    directions of the Adviser and of the Board of Trustees of the Trust and
    will conform to and comply with the requirements of the 1940 Act, the
    Internal Revenue Code of 1986, and all other applicable federal and state
    laws and regulations, as each is amended from time to time

(c) The Sub-Adviser shall determine the securities to be purchased or sold by
    the Portfolio and will place orders with or through such persons, brokers
    or dealers to carry out the policy with respect to brokerage set forth in
    the Portfolio's Registration Statement (as defined herein) and Prospectus
    or as the Board of Trustees or the Adviser may direct from time to time, in
    conformity with federal securities laws. In executing Portfolio
    transactions and selecting brokers or dealers, the Sub-Adviser will use its
    best efforts to seek on behalf of the Portfolio the best overall terms
    available. In assessing the best overall terms available for any
    transaction, the Sub-Adviser shall consider all factors that it deems
    relevant, including the breadth of the market in the security, the pace of
    the security, the financial condition and execution capability of the
    broker or dealer, and the reasonableness of the commission, if any, both
    for the specific transaction and on a continuing basis. In evaluating the
    best overall terms available, and in selecting the broker-dealer to execute
    a particular transaction the Sub-Adviser may also consider the brokerage
    and research services (as those terms are defined in Section 28(e) of the
    securities Exchange Act of 1934)

<PAGE>

    provided to the Portfolio and/or other accounts over which the Sub-Adviser
    or an affiliate of the Sub-Adviser may exercise investment discretion. The
    Sub-Adviser is authorized, subject to the prior approval of the Trust's
    Board of Trustees, to pay to a broker or dealer who provides such brokerage
    and research services a commission for executing a portfolio transaction
    for any of the Portfolios which is in excess of the amount of commission
    another broker or dealer would have charged for effecting that transaction
    if, but only if, the Sub-Adviser determines in good faith that such
    commission was reasonable in relation to the value of the brokerage and
    research services provided by such broker or dealer--viewed in terms of that
    particular transaction or terms of the overall responsibilities of the
    Sub-Adviser to the Portfolio.  In addition, the Sub-Adviser if authorized to
    allocate purchase and sale orders for portfolio securities to brokers or
    dealers (including brokers and dealers that are affiliated with the 
    Sub-Advisor or the Trust's principal underwriter to take into account
    the sale of shares of the Trust if the Sub-Adviser believes that the quality
    of the transaction and the commission are comparable to what they would be
    with other qualified firms.  In no instance, however, will any Portfolio's
    securities be purchased from or sold to the Sub-Adviser, the Trust's
    principal underwriter, or any affiliated person of either the Trust, the
    Sub-Adviser or the principal underwriter, acting as principal in the
    transaction, except to the extent permitted by the Securities and Exchange
    Commission and the 1940 Act.

(d) The Sub-Adviser shall maintain all books and records with respect to the
    Portfolio's portfolio transactions required by subparagraphs (b)(5), (6),
    (7), (9), (10) and (I 1) and paragraph (f) of Rule 31a-1 under the 1940
    Act and shall render to the Adviser or Board of Trustees such periodic and
    special reports as the Adviser or Board of Trustees may reasonably request.

    The Sub-Adviser shall keep the Portfolio's books and records required to be
    maintained by the Sub-Advisor of this Agreement and shall timely furnish to
    the Adviser all information relating to the Sub-Advisor services under this
    Agreement needed by the Adviser to keep the other books and records of the
    Portfolio required by Rule 3la-1 under the 1940 Act. The Sub-Adviser shall
    also furnish to the Adviser any other information that is required to be 
    filled by the Adviser or the Trust with the Securities and Exchange 
    Commission ("SEC") or sent to shareholders under the 1940 Act (including the
    rules adopted thereunder) or any exemptive or other relief that the Adviser
    or the Trust obtains from the SEC. The Sub-Adviser agrees that all records
    that it maintains on behalf of the Portfolio are property of the Portfolio
    and the Sub-Adviser will surrender promptly to the Portfolio any of such
    records upon the Portfolio's Request; provided, however, that the
    Sub-Adviser may retain a copy of such records. In addition, for the
    duration of this Agreement, the Sub-Adviser shall preserve for the periods
    prescribed by Rule 31a-2 under the 1940 Act any such records as are
    required to be maintained by it pursuant to this Agreement, and shall
    transfer said records to any successor Sub-Adviser upon the termination of
    this Agreement (or, if there is no successor Sub-Adviser, to the Adviser).

(e) The Sub-Adviser shall provide the Portfolio's custodian on each business
    day with information relating to all transactions concerning the
    Portfolio's assets and shall provide the Adviser with such information upon
    request of the Adviser.

(f) The investment management services provided by the Sub-Adviser under this
    Agreement are not to be deemed exclusive and the Sub-Adviser shall be free
    to render similar services to others, as long as such services Do not
    impair the services rendered to the Adviser or the Trust.

(g) The Sub-Adviser shall promptly notify the Adviser of any financial
    condition that is likely to impair the Sub-Adviser's ability to fulfill its
    commitment under this Agreement. 

    Services to be furnished by the Sub-Adviser under this Agreement may be
    furnished through the medium of any of the Sub-Adviser's partners,
    officers or employees.

    for all services to be provided to the Portfolio pursuant to the Advisory
    Agreement and shall oversee and review the Sub-Adviser's performance of

    shall be limited to the period and the amount set forth in Section 36(b)(3)
    of the 1940 Act), or a loss resulting from willful misfeasance, bad faith
    or negligence on the Sub-Adviser's part in the performance of its duties or
    from reckless disregard of its obligations and duties under this Agreement,
    except as may otherwise be provided under provisions of applicable state

                        INVESTMENT SUB-ADVISORY AGREEMENT
                       SEI INSTITUTIONAL INVESTMENTS TRUST

     AGREEMENT made this 14th day of June, 1996, by and among SEI Financial
Management Corporation, (the "Adviser") and Alliance Capital Management L.P.
(the "Sub-Adviser").

     WHEREAS, SEI Institutional Investments Trust, a Massachusetts business
trust (the "Trust") is registered as an open-end management investment company
under the Investment Company Act of 1940, as amended (the "1940 Act"); and

     WHEREAS, the Adviser has entered into an Investment Advisory Agreement
dated June 14, 1996 (the "Advisory Agreement") with the Trust, pursuant to which
the Adviser will act as investment adviser to the Large Cap Portfolio (the
"Portfolio"), which is a series of the Trust; and

     WHEREAS, the Adviser, with the approval of the Trust, desires to retain the
Sub-Adviser to provide investment advisory services to the Adviser in connection
with the management of the Portfolio, and the Sub-Adviser is willing to render
such investment advisory services.

     NOW, THEREFORE, the parties hereto agree as follows:

1.   DUTIES OF THE SUB-ADVISER. Subject to supervision by the Adviser and the
     Trust's Board of Trustees, the Sub-Adviser shall manage the investment of
     all of the securities and other assets of the Portfolio entrusted to it
     hereunder, including the purchase, retention and disposition of securities
     and other assets, in accordance with the Portfolio's investment objectives,
     policies and restrictions as stated in the Portfolio's prospectus and
     statement of additional information, as currently in effect and as amended
     or supplemented from time to time (referred to collectively as the
     "Prospectus"), and subject to the following:

(a)  The Sub-Adviser shall provide supervision of the Portfolio's investments
     and determine from time to time what investments and securities will be
     purchased, retained or sold by the Portfolio, and what portion of the
     assets will be invested or held uninvested in cash.

(b)  In the performance of its duties and obligations under this Agreement, the
     Sub-Adviser shall act in conformity with the Trust's Declaration of Trust
     (as defined herein) and the Prospectus and with the instructions and
     directions of the Adviser and of the Board of Trustees of the Trust and
     will conform to and comply with the requirements of the 1940 Act, the
     Internal Revenue Code of 1986, and all other applicable federal and state
     laws and regulations, as each is amended from time to time. The Adviser
     agrees promptly to deliver any amendment or supplement to the Prospectus to
     the Sub-Adviser on an on-going basis, and until the Adviser delivers any
     such amendment or supplement to its Sub-Adviser, the Sub-Adviser shall be
     fully protected in relying on the Prospectus as previously furnished.

(c)  The Sub-Adviser shall determine the securities to be purchased or sold by
     the Portfolio and will place orders with or through such persons, brokers
     or dealers to carry out the policy with respect to brokerage set forth in
     the Portfolio's Registration Statement and Prospectus or as the Board of
     Trustees or the Adviser may direct from time to time, in conformity with
     federal securities laws. In executing Portfolio transactions and selecting
     brokers or dealers, the Sub-Adviser will use its best efforts to seek on
     behalf of the Portfolio the best overall terms available. In assessing the
     best overall terms available for any transaction, the Sub-Adviser shall
     consider all factors that it deems relevant, including the breadth of the
     market in the security, the pace of the security, the financial condition
     and execution capability of the broker or dealer, and the reasonableness of
     the commission, if any, both for the specific transaction and on a
     continuing basis. In evaluating the best overall terms available, and in
     selecting the broker-dealer

<PAGE>

     to execute a particular transaction the Sub-Adviser may also consider the
     brokerage and research services (as those terms are defined in Section
     28(e) of the Securities Exchange Act of 1934) provided to the Portfolio
     and/or other accounts over which the Sub-Adviser or an affiliate of the
     Sub-Adviser may exercise investment discretion. The Sub-Adviser is
     authorized, subject to the prior approval of the Trust's Board of Trustees,
     to pay to a broker or dealer who provides such brokerage and research
     services a commission for executing a portfolio transaction for any of the
     Portfolios which is in excess of the amount of commission another broker or
     dealer would have charged for effecting that transaction if, but only if,
     the Sub-Adviser determines in good faith that such commission was
     reasonable in relation to the value of the brokerage and research services
     provided by such broker or dealer - - viewed in terms of that particular
     transaction or terms of the overall responsibilities of the Sub-Adviser to
     the Portfolio. In addition, the Sub-Adviser is authorized to allocate
     purchase and sale orders for portfolio securities to brokers or dealers
     (including brokers and dealers that are affiliated with the Sub-Adviser or
     the Trust's principal underwriter) to take into account the sale of shares
     of the Trust if the Sub-Adviser believes that the quality of the
     transaction and the commission are comparable to what they would be with
     other qualified firms. In no instance, however, will any Portfolio's
     securities be purchased from or sold to the Sub-Adviser, the Trust's
     principal underwriter, or any affiliated person of either the Trust, the
     Sub-Adviser or the principal underwriter, acting as principal in the
     transaction, except to the extent permitted by the Securities and Exchange
     Commission and the 1940 Act.

(d)  The Sub-Adviser shall maintain all books and records with respect to the
     Portfolio's portfolio transactions required by subparagraphs (b)(5), (6),
     (7), (9), (10) and (11) and paragraph (f) of Rule 31a-1 under the 1940 Act
     and shall render to the Adviser or Board of Trustees such periodic and
     special reports as the Adviser or Board of Trustees may reasonably request.

     The Sub-Adviser shall keep the Portfolio's books and records required to be
     maintained by the Sub-Adviser by this Agreement and shall timely furnish to
     the Adviser all information relating to the Sub-Adviser's services under
     this Agreement needed by the Adviser to keep the other books and records of
     the Portfolio required by Rule 31a-1 under the 1940 Act. The Sub-Adviser
     shall also furnish to the Adviser any other information that is required to
     be filed by the Adviser or the Trust with the Securities and Exchange
     Commission ("SEC") or sent to shareholders under the 1940 Act (including
     the rules adopted thereunder) or any exemptive or other relief that the
     Adviser or the Trust obtains from the SEC. The Sub-Adviser agrees that all
     records that it maintains on behalf of the Portfolio are property of the
     Portfolio and the Sub-Adviser will surrender promptly to the Portfolio any
     of such records upon the Portfolio's request; provided, however, that the
     Sub-Adviser may retain a copy of such records. In addition, for the
     duration of this Agreement, the Sub-Adviser shall preserve for the periods
     prescribed by Rule 31a-2 under the 1940 Act any such records as are
     required to be maintained by it pursuant to this Agreement, and shall
     transfer said records to any successor Sub-Adviser upon the termination of
     his Agreement (or, if there is no successor Sub-Adviser, to the Adviser).

(e)  The Sub-Adviser shall provide the Portfolio's custodian on each business
     day with information relating to all transactions concerning the
     Portfolio's assets and shall provide such information and such periodic or
     special reports as the Adviser or Board of Trustees may reasonably request.

(f)  Adviser understands that the Sub-Adviser now acts, will continue to act and
     may act in the future as investment manager or adviser to fiduciary and
     other managed accounts, and as investment manager or adviser to other
     investment companies, including any offshore entities, or accounts, and the
     Portfolio has no objection to the Sub-Adviser's so acting, provided that
     whenever the Portfolio and one or more other investment companies or
     accounts managed or advised by the Sub-Adviser have available funds for
     investment, investments suitable and appropriate for each will be allocated
     in accordance with a formula believed to be equitable to each company and
     account. The Adviser recognizes that in some cases this procedure may
     adversely affect the size of the position obtainable for the Portfolio. In
     addition, the Adviser understands that the persons employed by the
     Sub-Adviser to assist in the performance of the
<PAGE>

     Sub-Adviser's duties under this Agreement will not devote their full time
     to such service and nothing contained in this Agreement shall be deemed to
     limit or restrict the right of the Sub-Adviser or any affiliate of the
     Sub-Adviser to engage in and devote time and attention to other businesses
     or to render services of whatever kind or nature.

(g)  The Sub-Adviser shall promptly notify the Adviser of any financial
     condition that is likely to impair the Sub-Adviser's ability to fulfill its
     commitment under this Agreement.

     Services to be furnished by the Sub-Adviser under this Agreement may be
     furnished through the medium of any of the Sub-Adviser's partners, officers
     or employees.

2.   DUTIES OF THE ADVISER. The Adviser shall continue to have responsibility
     for all services to be provided to the Portfolio pursuant to the Advisory
     Agreement and shall oversee and review the Sub-Adviser's performance of its
     duties under this Agreement; provided, however, that nothing herein shall
     be construed to relieve the Sub-Adviser of responsibility for compliance
     with the Portfolio's investment objectives, policies, and restrictions, as
     provided in Section 1 hereunder.

3.   DELIVERY OF DOCUMENTS. The Adviser has furnished the Sub-Adviser with
     copies properly certified or authenticated of each of the following
     documents:

(a)  The Trust's Agreement and Declaration of Trust, as filed with the Secretary
     of State of the Commonwealth of Massachusetts (such Agreement and
     Declaration of Trust, as in effect on the date of this Agreement and as
     amended from time to time, herein called the "Declaration of Trust").

(b)  By-Laws of the Trust (such By-Laws, as in effect on the date of this
     Agreement and as amended from time to time, are herein called the
     "By-Laws");

(c)  Prospectus(es) of the Portfolio.

(d)  The Trust's most recent Registration Statement as filed with the Securities
     and Exchange Commission.

4.   COMPENSATION TO THE SUB-ADVISER. For the services to be provided by the
     Sub-Adviser pursuant to this Agreement, the Adviser will pay the
     Sub-Adviser, and the Sub-Adviser agrees to accept as full compensation
     therefor, a sub-advisory fee at the rate specified in Schedule A which is
     attached hereto and made part of this Agreement. The fee will be calculated
     based on the average monthly market value of investments under management
     and will be paid to the Sub-Adviser monthly. The Sub-Adviser may, in its
     discretion and from time to time, waive a portion of its fee

5.   LIMITATION OF LIABILITY OF THE SUB-ADVISER. The Sub-Adviser shall not be
     liable for any error of judgment or for any loss suffered by the Adviser in
     connection with the performance of its obligations under this Agreement,
     except a loss resulting from (i) willful misfeasance, bad faith or
     negligence on the Sub-Adviser's part in the performance of its duties, or
     (ii) reckless disregard of its obligations and duties under this Agreement,
     or (iii) a violation of law or any duty imposed by federal or state law.

6.   REPORTS. During the term of this Agreement, the Adviser agrees to furnish
     the Sub-Adviser at its principal office all prospectuses, proxy statements,
     reports to stockholders, sales literature or other materials prepared for
     distribution to stockholders of the Portfolios, the Trust or the public
     that refer to the Sub-Adviser or its clients in any way prior to use
     thereof and not to use material if the Sub-Adviser reasonably objects in
     writing within five business days (or such other period as may be mutually
     agreed) after receipt thereof. The Sub-Adviser's right to object to such
     materials is limited to the portions of such materials that expressly
     relate to the Sub-Adviser, its services and its clients. The Adviser agrees
     to use

<PAGE>

     its reasonable best efforts to ensure that materials prepared its employees
     or agents or its that refer to the Sub-Adviser or its clients in any way
     are consistent with those materials previously approved by the Sub-Adviser
     as referenced in the first sentence of this paragraph. Sales literature may
     be furnished to the Sub-Adviser by first class or overnight mail, facsimile
     transmission equipment or hand delivery.

7.   CHANGE IN THE SUB-ADVISER'S MEMBERSHIP. The Sub-Adviser agrees that it
     shall notify the Adviser of any change in the membership of the general
     partners of the Sub-Adviser within a reasonable time after such change.

8.   INDEMNIFICATION. The Sub-Adviser shall indemnify and hold harmless the
     Adviser from and against any and all claims, losses, liabilities or damages
     (including reasonable attorney's fees and other related expenses) howsoever
     arising from or in connection with this Agreement or the performance by the
     Sub-Adviser of its duties hereunder; provided, however, that the
     Sub-Adviser shall not be required to indemnify or otherwise hold the
     Adviser harmless under this Section 8 where the claim against, or the 
     loss, liability or damage experienced by the Adviser, is caused by or is
     otherwise directly related to the Adviser's own willful misfeasance, bad
     faith or negligence, or to the reckless disregard of its duties under this
     Agreement.

9.   DURATION AND TERMINATION. This Agreement shall become effective upon its
     approval by the Trust's Board of Trustees and by the vote of a majority of
     the outstanding voting securities of the Portfolio; provided, however, that
     at any time the Adviser shall have obtained exemptive relief from the SEC  
     permitting it to engage a Sub-Adviser without first obtaining approval of
     the Agreement from a majority of the outstanding voting securities of the
     Portfolio(s) involved, the Agreement shall become effective upon its
     approval by the Trust's Board of Trustees. Any Sub-Adviser so selected and
     approved shall be without the protection accorded by shareholder approval
     of an investment adviser's receipt of compensation under Section 36(b) of
     the 1940 Act.

     This Agreement shall continue in effect for a period of more than two years
     from the date hereof only so long as continuance is specifically approved
     at least annually in conformance with the 1940 Act; provided, however, that
     this Agreement may be terminated with respect to the Portfolio (a) by the
     Portfolio at any time, without the payment of any penalty, by the vote of a
     majority of Trustees of the Trust or by the vote of a majority of the
     outstanding voting securities of such Portfolio, (b) by the Adviser at any
     time, without the payment of any penalty, on not more than 60 days' nor
     less than 30 days' written notice to the other party, or (c) by the
     Sub-Adviser at any time, without the payment of any penalty, on 90 days'
     written notice to the other party. This Agreement shall terminate
     automatically and immediately in the event of its assignment, or in the
     event of a termination of the Adviser's agreement with the Trust. As used
     in this Section 9, the terms "assignment" and "vote of a majority of the   
     outstanding voting securities" shall have the respective meanings set forth
     in the 1940 Act and the rules and regulations thereunder, subject to such
     exceptions as may be granted by the Commission under the 1940 Act.

10.  GOVERNING LAW. This Agreement shall be governed by the internal laws of the
     Commonwealth of Massachusetts, without regard to conflict of law
     principles; provided, however, that nothing herein shall be construed as
     being inconsistent with the 1940 Act.

11.  SEVERABILITY. Should any part of this Agreement be held invalid by a court
     decision, statute, rule or otherwise, the remainder of this Agreement shall
     not be affected thereby. This Agreement shall be binding upon and shall
     inure to the benefit of the parties hereto and their respective successors.

12.  NOTICE: Any notice, advice or report to be given pursuant to this Agreement
     shall be deemed sufficient if delivered or mailed by registered, certified
     or overnight mail, postage prepaid addressed by the party

    invested or held uninvested in cash.

(b) In the performance of its duties and obligations under this Agreement, the
    Sub-Adviser shall act in conformity with the investment objectives,
    policies and limitations with respect to the Portfolio set forth in the
    Trust's Declaration of Trust (as defined herein) and the Prospectus and
    with applicable instructions and directions of the Adviser and of the Board
    of Trustees of the Trust and will conform to and comply with the
    requirements of the 1940 Act, the Internal Revenue Code of 1986, and all
    other applicable federal and state laws and regulations, as each is amended
    from time to time.

(c) The Sub-Adviser shall determine the Assets to be purchased or sold by the
    Portfolio as provided in subparagraph (a) and will place orders with or
    through such persons, brokers or dealers, including the Sub-Adviser or
    affiliates thereof, in accordance with the policy with respect to brokerage
    set forth in the Portfolio's Registration Statement and Prospectus or as
    the Trust's Board of Trustees or the Adviser may direct from time to time,
    in conformity with federal securities laws. In executing Portfolio
    transactions and selecting brokers or dealers, the Sub-Adviser will use its
    best efforts to seek on behalf of the Portfolio the best overall terms
    available. In assessing the best overall terms available for any
    transaction, the Sub-Adviser shall consider all factors that it deems
    relevant, including the breadth of the market in the security, the price of
    the security, the financial condition and execution capability of the broker
    or dealer, and the reasonableness of the commission, if any, both for the
    specific transaction and on a continuing basis. In evaluating the best
    overall terms available, and in selecting the broker-dealer to execute a
    particular transaction the Sub-Adviser may also consider the brokerage and
    research services (as those terms are defined in Section 28(e) of the
    Securities Exchange Act of 1934) provided to the Portfolio and/or other
    accounts over which the Sub-Adviser or an affiliate of the Sub-Adviser may
    exercise investment discretion. The Sub-Adviser is authorized to pay to a
    broker or dealer who provides such brokerage and research services a
    commission for executing a portfolio transaction for the Portfolio which is
    in excess of the amount of commission another broker or dealer would have
    charged for effecting that transaction if, but only if, the Sub-Adviser
    determines in good faith that such commission was reasonable in relation to
    the value of the brokerage and research services provided by such broker or
    dealer - - viewed in terms of that particular transaction or in terms of
    the overall

<PAGE>

    responsibilities of the Sub-Adviser to the Portfolio and the accounts as 
    to which the Sub-Adviser excercises investment discretion.  It is recognized
    that the services provided by such brokers or dealers may be useful to the 
    Sub-Adviser in connection with the Sub-Adviser's services to other clients.
    In no instance, however, will any of the Portfolio's Assets be purchased 
    from or sold to the Adviser, Sub-Adviser, the Trust's principal underwriter,
    or any affiliated person of either the Trust, the Sub-Adviser or the 
    principal underwriter, acting as principal in the transaction, except to the
    extent permitted by the Securities and Exchange Commission and the 1940 Act.
    On occasions when the Sub-Adviser deems the purchase or sale of a security
    to be in the best interest of the Portfolio as well as other customers, the
    Sub-Adviser may, to the extent permitted by applicable laws and regulations,
    but shall not be obligated to, aggregate the securities to be sold or
    purchased in order to obtain the best execution and lower brokerage 
    commissions, if any.  In such event, allocation of the securities so 
    purchased or sold, as well as expenses incurred in the transaction, will be 
    made by the Sub-Adviser in the manner it considers to be fair and equitable
    and consistent with its fiduciary obligation to the Portfolio, and, if 
    applicable, to other customers.

    The Adviser acknowledges that in order to comply with federal securities
    laws and related regulatory requirements, there may be periods when the
    Sub-Adviser will not be permitted to initiate or recommend certain types of
    transactions in the securities or issuers for which affiliates of the
    Sub-Adviser are performing investment banking services, and neither the
    Trust nor the Adviser will be advised of that fact. For example, during
    certain periods when affiliates of the Sub-Adviser are engaged in an
    underwriting or other distribution of a company's securities, the
    Sub-Adviser may be prohibited from purchasing or recommending the purchase
    of certain securities of that company for its clients. Similarly, the
    Sub-Adviser may on occasion be prohibited from selling or recommending the
    sale of securities of a company for which affiliates are providing
    investment banking services.

(d) The Sub-Adviser shall maintain all books and records with respect to
    transactions involving the Assets required by subparagraphs (b)(5), (6),
    (7), (9), (10) and (11) and paragraph (f) of Rule 31a-1 under the 1940 Act
    and shall render to the Adviser or the Trust's Board of Trustees such
    periodic and special reports as the Adviser or the Trust's Board of
    Trustees may reasonably request.

    The Sub-Adviser shall keep the books and records relating to the Assets
    required to be maintained by the Sub-Adviser under this Agreement and shall
    timely furnish to the Adviser all information relating to the Sub-Adviser's
    services under this Agreement needed by the Adviser to keep the other books
    and records of the Portfolio required by Rule 31a-1 under the 1940 Act. The
    Sub-Adviser shall also furnish to the Adviser any other information
    relating to the Assets that is required to be filed by the Adviser or the
    Trust with the Securities and Exchange Commission ("SEC") or sent to
    shareholders under the 1940 Act (including the rules adopted thereunder) or
    any exemptive or other relief that the Adviser or the Trust obtains from
    the SEC. The Sub-Adviser agrees that all records that it maintains on
    behalf of the Portfolio are property of the Portfolio and the Sub-Adviser
    will surrender promptly to the Portfolio any of such records upon the
    Portfolio's request; provided, however, that the Sub-Adviser may retain a
    copy of such records. In addition, for the duration of this Agreement, the
    Sub-Adviser shall preserve for the periods prescribed by Rule 31a-2 under
    the 1940 Act any such records as are required to be maintained by it
    pursuant to this Agreement, and shall transfer said records to any
    successor Sub-Adviser upon the termination of this Agreement (or, if there
    is no successor Sub-Adviser, to the Adviser).

(e) The Sub-Adviser shall provide the Portfolio's custodian on each business
    day with information relating to all transactions concerning the Assets and
    shall provide the Adviser with such information upon request of the
    Adviser.

(f) The investment management services provided by the Sub-Adviser under this
    Agreement are not to be deemed exclusive and the Sub-Adviser shall be free
    to render similar services to other clients, as long as such services do
    not impair the services rendered to the Adviser or the Trust. The
    Sub-Adviser may give advice, and take action, with respect to any of its
    other clients that may differ from the advice given, or the time or nature
    of action taken, with respect to the Portfolio. The Sub-Adviser shall have
    no obligation to purchase or sell for the Portfolio or to recommend for
    purchase or sale by the Portfolio, any securities that the Sub-Adviser, its
    principals, affiliates or employees may purchase for themselves or for any
    other clients.

(g) The Sub-Adviser shall promptly notify the Adviser of any financial
    condition that is likely to impair the Sub-Adviser's ability to fulfill its
    commitment under this Agreement.

    Services to be furnished by the Sub-Adviser under this Agreement may be
    furnished through the medium of any of the Sub-Adviser's partners, officers
    or employees.

2.  DUTIES OF THE ADVISER. The Adviser shall continue to have responsibility
    for all services to be provided to the Portfolio pursuant to the Advisory
    Agreement and shall oversee and review the Sub-Adviser's performance of its
    duties under this Agreement; provided, however, that in connection with its
    management of the Assets, nothing herein shall be construed to relieve the
    Sub-Adviser of responsibility for compliance, with respect to the
    Portfolio, with the Trust's Declaration of Trust (as defined herein), the
    Prospectus, the instructions and directions of the Board of Trustees of the
    Trust, the requirements of the 1940 Act, the Internal Revenue Code of 1986,
    and all other applicable federal and state laws and regulations, as each is
    amended from time to time.

3.  DELIVERY OF DOCUMENTS. The Adviser has furnished the Sub-Adviser with
    copies properly certified or authenticated of each of the following
    documents:

(a) The Trust's Agreement and Declaration of Trust, as filed with the Secretary
    of State of the Commonwealth of Massachusetts (such Agreement and
    Declaration of Trust, as in effect on the date of this Agreement and as
    amended from time to time, herein called the "Declaration of Trust");

(b) By-Laws of the Trust (such By-Laws, as in effect on the date of this
    Agreement and as amended from time to time, are herein called the
    "By-Laws");

(c) Prospectus(es) of the Portfolio.

    Copies of any amendments to the above documents will be furnished promptly
    to the Sub-Adviser.

4.  COMPENSATION TO THE SUB-ADVISER. For the services to be provided by the
    Sub-Adviser pursuant to this Agreement, the Adviser will pay the
    Sub-Adviser, and the Sub-Adviser agrees to accept as full compensation
    therefor, a sub-advisory fee at the rate specified in the Schedule(s) which
    is attached hereto and made part of this Agreement. The fee will be
    calculated based on the average monthly market value of the Assets under
    the Sub-Adviser's management and will be paid to the Sub-Adviser monthly.
    Except as may otherwise be prohibited by law or regulation (including any
    then current SEC staff interpretation), the Sub-Adviser may, in its
    discretion and from time to time, waive a portion of its fee.

5.  LIMITATION OF LIABILITY OF THE SUB-ADVISER. The Sub-Adviser shall not be
    liable for any error of judgment or for any loss suffered by the Adviser in
    connection with the performance of its obligations under this Agreement,
    except a loss resulting from a breach of fiduciary duty with respect to the
    receipt of compensation for services (in which case any award of damages
    shall be limited to the period and the amount set forth in Section 36(b)(3)
    of the 1940 Act), or a loss resulting from willful misfeasance, bad faith
    or negligence on the Sub-Adviser's part in the performance of its duties or
    from reckless disregard of its obligations and duties under this Agreement,
    except as may otherwise be provided under provisions of applicable state
    law which cannot be waived or modified hereby.

    The Sub-Adviser shall not be responsible for any loss incurred by reason of
    any act or omission of any broker-dealer; provided, however, that the
    Sub-Adviser shall use reasonable care in its selection and use of brokers
    in effecting transactions for the Portfolio. The Sub-Adviser shall have no
    obligation to seek to obtain any material non-public ("inside") information
    about any issuer of securities, nor to purchase or sell, or to recommend
    for purchase or sale, for the Portfolio the securities of any issuer on the
    basis of any such information as may come into its possession.

    The Adviser acknowledges and agrees that the Sub-Adviser makes no
    representation and warranty, express or implied, that any level of
    performance or investment results will be achieved by the Portfolio or that
    the Portfolio will perform comparably with any standard or index, including
    other clients of the Sub-Adviser whether public or private.

6.  REPORTS. During the term of this Agreement, the Adviser agrees to furnish
    the Sub-Adviser at its principal office all prospectuses, proxy statements,
    reports to stockholders, sales literature or other materials prepared for
    distribution to stockholders of the Portfolios, the Trust or the public that
    refer to the Sub-Adviser or its clients in any way prior to use thereof and
    not to use such material if the Sub-Adviser reasonably objects in writing
    within five business days (or such other period as may be mutually agreed)
    after receipt thereof. The Sub-Adviser's right to object to such materials
    is limited to the portions of such materials that expressly relate to the
    Sub-Adviser; its services and its clients. The Adviser agrees to use its
    reasonable best efforts to ensure that materials prepared by

<PAGE>

    its agents or its affiliates that refer to the Sub-Adviser or its clients
    in any way are consistent with those materials previously approved by the
    Sub-Adviser as referenced in the first sentence of this paragraph. Sales
    literature may be furnished to the Sub-Adviser by first class or overnight
    mail, facsimile transmission equipment or hand delivery.

7.  PORTFOLIO COMPOSITION. The Adviser shall provide (or cause the Trust's
    custodian to provide) timely information to the Sub-Adviser regarding such
    matters as the composition of the Assets and cash available for investment
    in the Portfolio and cash requirements (with respect to the redemption of
    Portfolio shares) and such other information as the parties may reasonably
    agree upon.

8.  EXPENSES. The Sub-Adviser shall bear expenses incurred by it in connection
    with its duties hereunder, including payment for compensation of and office
    space for its officers and employees engaged in providing services
    hereunder, but shall not be responsible for any expenses of the Trust.

9.  CUSTODY. The cash and assets of the Portfolio shall be held by CoreStates
    Bank, N A. (the "Custodian"), which the Adviser hereby represents has
    agreed to act as custodian for the Portfolio. The Sub-Adviser shall at no
    time have custody or physical control of the Assets in the Portfolio. In
    addition, the Sub-Adviser shall not be liable for any act or omission of
    the Custodian. The Sub-Adviser shall give instructions to the Custodian in
    writing or orally (at the discretion of the Custodian) and confirmed in
    writing as soon as practicable thereafter. The Adviser shall instruct the
    Custodian to provide the Sub-Adviser with such periodic reports concerning
    the status of the Portfolio as the Sub-Adviser and the Adviser may agree
    from time to time. The Adviser shall provide the Sub-Adviser with a copy of
    the Portfolio's agreement with the Custodian and any modification thereto
    and will notify the Sub-Adviser in advance of a change in the Custodian.

10. REPRESENTATIONS AND WARRANTIES OF THE ADVISER. The Adviser represents and
    warrants to the Sub-Adviser that (a) the Adviser has the authority to act

    or by which its assets may be bound or any statute or any rule, regulation
    or order of any government agency or body; (e) the Assets of the Portfolio
    do not and will not constitute assets of any employee benefit plan within
    the meaning of Section 3(3) of the Employee Retirement Security Act of 1974
    or Section 4975(e) of the Internal Revenue Code of 1986 and this Agreement
    and the transactions contemplated hereby will not constitute an investment
    by a "benefit plan investor" within the meaning of DOL Reg. Section 2510.3
    -101; and (f) the Adviser has received a copy of Part II of the
    Sub-Adviser's Form ADV as most recently filed with the SEC.

    the Sub-Adviser shall be in writing signed either (a) by a director or
    officer of the Adviser, or (b) by a duly authorized agent of the Adviser.

    signed in the appropriate manner with respect to any instruction, direction

    when acting upon any instrument, certificate or paper the Sub-Adviser
    reasonably believes to be genuine and to be signed or presented by the
    proper person or persons. The Sub-Adviser shall be under no duty to make
    any investigation or inquiry as to any statement contained in any such
    writing and may accept the same as conclusive evidence of the truth and
    accuracy of the statements therein contained.

12. PROXIES, TENDER OFFERS, CLASS ACTIONS, ETC. Subject to any other written
    instructions of the Adviser, the Sub-Adviser is hereby appointed the 
    Adviser's agent and attorney-in-fact on behalf of the Portfolio in its 
    discretion to vote, tender or convert any of the Assets; to execute proxies,
    waivers, consents, account documentation, agreements, contracts, and other
    instruments with respect to the Assets; to endorse, transfer or deliver the
    Assets and to participate in or consent to any class action, plan of
    reorganization, merger, combination, consolidation, liquidation or similar
    plan with reference to the Assets; and the Sub-Adviser shall not incur any
    liability to the Adviser or the Portfolio by reason of any exercise of, or
    failure to exercise, any such discretion. Notwithstanding the provisions of
    this Section 12, if the Sub-Adviser determines that it, or any of its
    affiliates, has an adverse or potentially adverse interest with respect to
    the vote or other requested action, the Sub-Adviser shall so inform the
    Adviser, which shall thereupon become responsible for the determination on
    such vote or other action.

    Sub-Adviser, its officers, directors, employees, agents and each person, if
    any, who controls the Sub-Adviser within the meaning of Section 15 of the 
    Securities Act of 1933 (the "1933 Act") (any and all such persons shall be
    referred to as "Sub-Adviser Indemnified Party"), against any and all 
    claims, losses, liabilities or damages (including reasonable attorney's 
    fees and other related expenses) howsoever arising from or in connection

    hereunder; provided, however, that the Adviser shall not be required to 
    indemnify or otherwise hold any particular Sub-Adviser Indemnified Party 
    harmless under this Section 13 where the claim against, or the loss, 
    liability or damage experienced by the Sub-Adviser Indemnified Party is 
    caused by or is otherwise directly related to such Sub-Adviser Indemnified 
    Party's own willful misfeasance, bad faith or negligence, or to the 
    reckless disregard of its duties under this Agreement.

(b) The Sub-Adviser shall indemnify and hold harmless the Adviser, its
    officers, directors, employees, agents and each person, if any, who
    controls the Adviser within the meaning of Section 15 of the 1933 Act (any
    and all such persons shall be referred to as "Adviser Indemnified Party")
    from and against any and all claims, losses, liabilities or damages
    (including reasonable attorney's fees and other related expenses) howsoever
    arising from or in connection with this Agreement or the performance by the
    Sub-Adviser of its duties hereunder; provided, however, that the
    Sub-Adviser shall not be required to indemnify or otherwise hold any
    particular Adviser Indemnified Party harmless under this Section 13 where

    of any penalty, on 90 days' written notice to the Adviser.  This Agreement 
    shall terminate automatically and immediately in the event of its 
    assignment, or in the event of a termination of the Adviser's agreement with
    the Trust. As used in this Section 14, the terms "assignment" and "vote of a
    majority of the outstanding voting securities" shall have the respective 
    meanings set forth in the 1940 Act and the rules and regulations thereunder,
    subject to such exceptions as may be granted by the SEC under the 1940 Act.

                         SEI INSTITUTIONAL INVESTMENTS TRUST

    AGREEMENT made this 14th day of June, 1996, between SEI Financial
Management Corporation, (the "Adviser") and BlackRock Financial Management, Inc.
(the "Sub-Adviser").

    WHEREAS, SEI Institutional Investments Trust, a Massachusetts business
trust (the "Trust") is registered as an open-end management investment company
under the Investment Company Act of 1940, as amended (the "1940 Act"); and

    WHEREAS, the Adviser has entered into an Investment Advisory Agreement
dated June 14, 1996 (the "Advisory Agreement") with the Trust, pursuant to
which the Adviser will act as investment adviser to the Core Fixed Income
Portfolio (the "Portfolio"), which is a series of the Trust; and

    WHEREAS, the Adviser, with the approval of the Trust, desires to retain the
Sub-Adviser to provide investment advisory services to the Adviser in connection
with the management of the Portfolio, and the Sub-Adviser is willing to render
such investment advisory services.

    NOW, THEREFORE, the parties hereto agree as follows:

    1.   DUTIES OF THE SUB-ADVISER. Subject to supervision by the Adviser and
         the Trust's Board of Trustees, the Sub-Adviser shall manage all of the
         securities and other assets of the Portfolio entrusted to it hereunder
         (the "Assets"), including the purchase, retention and disposition of
         the Assets, in accordance with the Portfolio's investment objectives,
         policies and restrictions as stated in the Portfolio's prospectus and
         statement of additional information, as currently in effect and as
         amended or supplemented from time to time (referred to collectively as
         the "Prospectus"), and subject to the following:

    (a)  The Sub-Adviser shall, in consultation with and subject to the
         direction of the Adviser, determine from time to time what Assets will
         be purchased, retained or sold by the Portfolio, and what portion of
         the Assets will be invested or held uninvested in cash.

    (b)  In the performance of its duties and obligations under this Agreement,
         the Sub-Adviser shall act in conformity with the Trust's Declaration
         of Trust (as defined herein) and the Prospectus and with the
         instructions and directions of the Adviser and of the Board of
         Trustees of the Trust and will conform to and comply with the
         requirements of the 1940 Act, the Internal Revenue Code of 1986, and
         all other applicable federal and state laws and regulations, as each
         is amended from time to time.

    (c)  The Sub-Adviser shall determine the Assets to be purchased or sold by
         the Portfolio as provided in subparagraph (a) and will place orders
         with or through such persons, brokers or dealers to carry out the
         policy with respect to brokerage set forth in the Portfolio's
         Registration Statement (as defined herein) and Prospectus or as the
         Board of Trustees or the Adviser may direct from time to time, in
         conformity with federal securities laws. In executing Portfolio
         transactions and selecting brokers or dealers, the Sub-Adviser will
         use its best efforts to seek on behalf of the Portfolio the best
         overall terms available. In assessing the best overall terms available
         for any transaction, the Sub-Adviser shall consider all factors that
         it deems relevant, including the breadth of the market in the
         security, the price of the security, the financial condition and
         execution capability of the broker or dealer, and the reasonableness
         of the commission, if any, both for the specific transaction and on a
         continuing basis. In evaluating the best overall terms available, and
         in selecting the broker-dealer to execute a particular transaction,
         the Sub-Adviser may also consider the brokerage and research services
         provided (as those terms are defined in Section 28(e)

<PAGE>

         of the Securities Exchange Act of 1934). Consistent with any
         guidelines established by Board of Trustees of the Trust, the
         Sub-Adviser is authorized to pay to a broker or dealer who provides
         such brokerage and research services a commission for executing a
         portfolio transaction for the Portfolio which is in excess of the
         amount of commission another broker or dealer would have charged for
         effecting that transaction if, but only if, the Sub-Adviser determines
         in good faith that such commission was reasonable in relation to the
         value of the brokerage and research services provided by such broker
         or dealer -- viewed in terms of that particular transaction or terms of
         the overall responsibilities of the Sub-Adviser to the Portfolio. In
         addition, the Sub-Adviser if authorized to allocate purchase and sale
         orders for securities to brokers or dealers (including brokers and
         dealers that are affiliated with the Adviser, Sub-Adviser or the 
         Trust's principal underwriter) to take into account the sale of shares
         of the Trust if the Sub-Adviser believes that the quality of the
         transaction and the commission are comparable to what they would be
         with other qualified firms. In no instance, however, will the
         Portfolio's Assets be purchased from or sold to the Adviser,
         Sub-Adviser, the Trust's principal underwriter, or any affiliated
         person of either the Trust, Adviser, the Sub-Adviser or the principal
         underwriter, acting as principal in the transaction, except to the
         extent permitted by the Securities and Exchange Commission ("SEC") and
         the 1940 Act.

    (d)  The Sub-Adviser shall maintain all books and records with respect to
         transactions involving the Assets required by subparagraphs (b)(5),
         (6), (7), (9), (10) and (11) and paragraph (f) of Rule 31a-1 under the
         1940 Act. The Sub-Adviser shall provide to the Adviser or the Board of
         Trustees such periodic and special reports, balance sheets or
         financial information, and such other information with regard to its
         affairs as the Adviser or Board of Trustees may reasonably request. 

         The Sub-Adviser shall keep the books and records relating to the
         Assets required to be maintained by the Sub-Adviser under this
         Agreement and shall timely furnish to the Adviser all information
         relating to the Sub-Adviser's services under this Agreement needed by
         the Adviser to keep the other books and records of the Portfolio
         required by Rule 31a-1 under the 1940 Act. The Sub-Adviser shall also
         furnish to the Adviser any other information relating to the Assets
         that is required to be filed by the Adviser or the Trust with the SEC
         or sent to shareholders under the 1940 Act (including the rules
         adopted thereunder) or any exemptive or other relief that the Adviser
         or the Trust obtains from the SEC. The Sub-Adviser agrees that all
         records that it maintains on behalf of the Portfolio are property of
         the Portfolio and the Sub-Adviser will surrender promptly to the
         Portfolio any of such records upon the Portfolio's request; provided,
         however, that the Sub-Adviser may retain a copy of such records. In
         addition, for the duration of this Agreement, the Sub-Adviser shall
         preserve for the periods prescribed by Rule 31a-2 under the 1940 Act
         any such records as are required to be maintained by it pursuant to
         this Agreement, and shall transfer said records to any successor
         sub-adviser upon the termination of this Agreement (or, if there is no
         successor sub-adviser, to the Adviser).

    (e)  The Sub-Adviser shall provide the Portfolio's custodian on each
         business day with information relating to all transactions concerning
         the Portfolio's Assets and shall provide the Adviser with such
         information upon request of the Adviser.

    (f)  The investment management services provided by the Sub-Adviser under
         this Agreement are not to be deemed exclusive and the Sub-Adviser
         shall be free to render similar services to others, as long as such
         services do not impair the services rendered to the Adviser or the
         Trust.

    (g)  The Sub-Adviser shall promptly notify the Adviser of any financial
         condition that is likely to impair the Sub-Adviser's ability to
         fulfill its commitment under this Agreement.

                                         -2-

    (h)  The Sub-Adviser shall review all proxy solicitation materials and be
         responsible for voting and handling all proxies in relation to the
         securities held in the Portfolio. The Adviser shall instruct the
         custodian and other parties providing services to the Portfolio to
         promptly forward misdirected proxies to the Sub-Adviser.

         Services to be furnished by the Sub-Adviser under this Agreement may
         be furnished through the medium of any of the Sub-Adviser's partners,
         officers or employees.

    2.   DUTIES OF THE ADVISER. The Adviser shall continue to have
         responsibility for all services to be provided to the Portfolio
         pursuant to the Advisory Agreement and shall oversee and review the
         Sub-Adviser's performance of its duties under this Agreement;
         provided, however, that in connection with its management of the
         Assets, nothing herein shall be construed to relieve the Sub-Adviser
         of responsibility for compliance with the Trust's Declaration of Trust
         (as defined herein), the Prospectus, the instructions and directions
         of the Board of Trustees of the Trust, the requirements of the 1940
         Act, the Internal Revenue Code of 1986, and all other applicable
         federal and state laws and regulations, as each is amended from time
         to time.

    3.   DELIVERY OF DOCUMENTS. The Adviser has furnished the Sub-Adviser with
         copies properly certified or authenticated of each of the following
         documents:

    (a)  The Trust's Agreement and Declaration of Trust, as filed with the
         Secretary of State of the Commonwealth of Massachusetts (such
         Agreement and Declaration of Trust, as in effect on the date of this
         Agreement and as amended from time to time, herein called the
         "Declaration of Trust"); 

    (b)  By-Laws of the Trust (such By-Laws, as in effect on the date of this
         Agreement and as amended from time to time, are herein called the
         "By-Laws");

    (c)  Prospectus(es) of the Portfolio.

    4.   COMPENSATION TO THE SUB-ADVISER. For the services to be provided by
         the Sub-Adviser pursuant to this Agreement, the Adviser will pay the
         Sub-Adviser, and the Sub-Adviser agrees to accept as full compensation
         therefor, a sub-advisory fee at the rate specified in the Schedule(s)
         which is attached hereto and made part of this Agreement. The fee will
         be calculated based on the average monthly market value of the Assets
         under the Sub-Adviser's management and will be paid to the Sub-Adviser
         monthly. Except as may otherwise be prohibited by law or regulation
         (including any then current SEC staff interpretation), the Sub-Adviser
         may, in its discretion and from time to time, waive a portion of its
         fee.

    5.   INDEMNIFICATION. The Sub-Adviser shall indemnify and hold harmless the
         adviser from and against any and all claims, losses, liabilities or
         damages (including reasonable attorney's fees and other related
         expenses) howsoever arising from or in connection with the performance
         of the Sub-Adviser's obligations under this Agreement; provided, 
         however, that the Sub-Adviser's obligation under this Section 5 shall
         be reduced to the extent that the claim against, or the loss, liability
         or damage experienced by the Adviser is caused by or is otherwise 
         directly related to the Adviser's own willful misfeasance, bad faith or
         negligence, or to the reckless disregard of its duties under this
         Agreement.

         The Adviser shall indemnify and hold harmless the Sub-Adviser from and
         against any and all claims, losses, liabilities or damages (including
         reasonable attorney's fees and other related

                                         -3-

<PAGE>
         expenses) howsoever arising from or in connection with the
         performance of the Adviser's obligations under this Agreement;
         provided, however, that the Adviser's obligation under this Section 5
         shall be reduced to the extent that the claim against, or the loss,
         liability or damage experienced by the Sub-Adviser, is caused by or is
         otherwise directly related to the Sub-Adviser's own willful
         misfeasance, bad faith or negligence, or to the reckless disregard of
         its duties under this Agreement.

    6.   DURATION AND TERMINATION. This Agreement shall become effective upon
         its approval by the Trust's Board of Trustees and by the vote of a
         majority of the outstanding voting securities of the Portfolio. This
         Agreement shall continue in effect for a period of more than two years
         from the date hereof only so long as continuance is specifically
         approved at least annually in conformance with the 1940 Act; provided,
         however, that this Agreement may be terminated with respect to the
         Portfolio (a) by the Portfolio at any time, without the payment of any
         penalty, by the vote of a majority of Trustees of the Trust or by the
         vote of a majority of the outstanding voting securities of the
         Portfolio and, (b) by the Adviser at any time, without the payment of
         any penalty, on not more than 60 days' nor less than 30 days' written
         notice to the Sub-Adviser, or (c) by the Sub-Adviser at any time,
         without the payment of any penalty, on 90 days' written notice to the 
         Adviser. This Agreement shall terminate automatically and immediately
         in the event of its assignment, or in the event of a termination of the
         Adviser's agreement with the Trust. As used in this Section 6, the
         terms "assignment" and "vote of a majority of the outstanding voting
         securities" shall have the respective meanings set forth in the 1940
         Act and the rules and regulations thereunder, subject to such
         exceptions as may be granted by the Commission under the 1940 Act.

    7.   GOVERNING LAW. This Agreement shall be governed by the internal laws
         of the Commonwealth of Massachusetts, without regard to conflict of
         law principles; provided, however, that nothing herein shall be
         construed as being inconsistent with the 1940 Act.

    8.   SEVERABILITY. Should any part of this Agreement be held invalid by a
         court decision, statute, rule or otherwise, the remainder of this
         Agreement shall not be affected thereby. This Agreement shall be
         binding upon and shall inure to the benefit of the parties hereto and
         their respective successors.

    9.   NOTICE: Any notice, advice or report to be given pursuant to this
         Agreement shall be deemed sufficient if delivered or mailed by

                        INVESTMENT SUB-ADVISORY AGREEMENT
                       SEI INSTITUTIONAL INVESTMENTS TRUST

     AGREEMENT made this 14th day of June, 1996, between SEI Financial
Management Corporation, (the "Adviser") and Boston Partners Asset Management,
L.P. (the "Sub-Adviser").

     WHEREAS, SEI Institutional Investments Trust, a Massachusetts business
trust (the "Trust" ) is registered as an open-end management investment company
under the Investment Company Act of 1940, as amended (the "1940 Act"); and

     WHEREAS, the Adviser has entered into an Investment Advisory Agreement
dated June 14, 1996 (the "Advisory Agreement") with the Trust, pursuant to
which the Adviser will act as investment adviser to the Small Cap Portfolio (the
"Portfolio"), which is a series of the Trust; and

     WHEREAS, the Adviser, with the approval of the Trust, desires to retain the
Sub-Adviser to provide investment advisory services to the Adviser in connection
with the management of the Portfolio, and the Sub-Adviser is willing to render
such investment advisory services.

     NOW, THEREFORE, the parties hereto agree as follows:

1.   DUTIES OF THE SUB-ADVISER. Subject to supervision by the Adviser and the
     Trust's Board of Trustees, the Sub-Adviser shall manage all of the
     securities and other assets of the Portfolio entrusted to it hereunder (the
     "Assets"), including the purchase, retention and disposition of the Assets,
     in accordance with the Portfolio's investment objectives, policies and
     restrictions as stated in the Portfolio's prospectus and statement of
     additional information, as currently in effect and as amended or
     supplemented from time to time (referred to collectively as the
     "Prospectus"), and subject to the following:

(a)  The Sub-Adviser shall, on a discretionary basis, in consultation with and
     subject to the direction of the Adviser, determine from time to time what
     Assets will be purchased, retained or sold by the Portfolio, and what
     portion of the Assets will be invested or held uninvested in cash.

(b)  In the performance of its duties and obligations under this Agreement, the
     Sub-Adviser shall act in conformity with the Trust's Declaration of Trust
     (as defined herein) and the Prospectus and with the instructions and
     directions of the Adviser and of the Board of Trustees of the Trust and
     will conform to and comply with the requirements of the 1940 Act, the
     Internal Revenue Code of 1986, and all other applicable federal and state
     laws and regulations, as each is amended from time to time.

(c)  The Sub-Adviser shall determine the Assets to be purchased or sold by the
     Portfolio as provided in subparagraph (a) and will place orders with or
     through such persons, brokers or dealers to carry out the policy with
     respect to brokerage set forth in the Portfolio's Registration Statement
     (as defined herein) and Prospectus or as the Board of Trustees or the
     Adviser may direct from time to time, in conformity with federal securities
     laws. In executing Portfolio transactions and selecting brokers or dealers,
     the Sub-Adviser will use its best efforts to seek on behalf of the
     Portfolio the best overall terms available. In assessing the best overall
     terms available for any transaction, the Sub-Adviser shall consider all
     factors that it deems relevant, including the breadth of the market in the
     security, the price of the security, the financial condition and execution
     capability of the broker or dealer, and the reasonableness of the
     commission, if any, both for the specific transaction and on a continuing
     basis. In evaluating the best overall terms available, and in selecting the
     broker-dealer to execute a particular transaction, the Sub-Adviser may also
     consider the brokerage and research services provided (as those terms are
     defined in Section 28(e) of the Securities Exchange Act of 1934).
     Consistent with any guidelines established by the Board of Trustees of the
     Trust, the Sub-Adviser is authorized to pay to a broker or dealer who
     provides such brokerage and research services a commission for executing a
     portfolio transaction for the Portfolio which is in excess of the amount of
     commission another broker or dealer would have charged for effecting that
     transaction if, but only if, the Sub-Adviser determines in good faith that
     such commission was reasonable in relation to the value of the brokerage
     and research services provided by such broker or dealer--viewed in terms of
     that particular transaction or terms of the overall responsibilities of the
     Sub-Adviser to the Portfolio.  In addition, the Sub-Adviser if authorized
     to allocate purchase and sale orders for securities to brokers or dealers
<PAGE>

     (including brokers and dealers that are affiliated with the Adviser,
     Sub-Adviser or the Trust's principal underwriter) to take into account the
     sale of shares of the Trust if the Sub-Adviser believes that the quality of
     the transaction and the commission are comparable to what they would be
     with other qualified firms.  In no instance, however, will the Portfolio's
     Assets be purchased from or sold to the Adviser, Sub-Adviser, the Trust's
     principal underwriter, or any affiliated person of either the Trust,
     Adviser, the Sub-Adviser or the principal underwriter, acting as principal
     in the transaction, except to the extent permitted by the Securities and
     Exchange Commission ("SEC") and the 1940 Act.

(d)  The Sub-Adviser shall maintain all books and records with respect to
     transactions involving the Assets required by subparagraphs (b)(5), (6),
     (7), (9), (10) and (11) and paragraph (f) of Rule 31a-1 under the 1940
     Act. The Sub-Adviser shall provide to the Adviser or the Board of Trustees
     such periodic and special reports, balance sheets or financial 
     information, and such other information with regard to its affairs as the 
     Adviser or Board of Trustees may reasonably request.

     The Sub-Adviser shall keep the books and records relating to the Assets
     required to be maintained by the Sub-Adviser under this Agreement and shall
     timely furnish to the Adviser all information relating to the Sub-Adviser's
     services under this Agreement needed by the Adviser to keep the other books
     and records of the Portfolio required by Rule 31a-1 under the 1940 Act. The
     Sub-Adviser shall also furnish to the Adviser any other information
     relating to the Assets that is required to be filed by the Adviser or the
     Trust with the SEC or sent to shareholders under the 1940 Act (including
     the rules adopted thereunder) or any exemptive or other relief that the
     Adviser or the Trust obtains from the SEC.  The Sub-Adviser agrees that all
     records that it maintains on behalf of the Portfolio are property of the
     Portfolio and the Sub-Adviser will surrender promptly to the Portfolio any
     of such records upon the Portfolio's request; provided, however, that the
     Sub-Adviser may retain a copy of such records. In addition, for the
     duration of this Agreement, the Sub-Adviser shall preserve for the periods
     prescribed by Rule 31a-2 under the 1940 Act any such records as are
     required to be maintained by it pursuant to this Agreement, and shall
     transfer said records to any successor sub-adviser upon the termination of
     this Agreement (or, if there is no successor sub-adviser, to the Adviser).

(e)  The Sub-Adviser shall provide the Portfolio's custodian on each business
     day with information relating to all transactions concerning the
     Portfolio's Assets and shall provide the Adviser with such information upon
     request of the Adviser.

(f)  The investment management services provided by the Sub-Adviser under this
     Agreement are not to be deemed exclusive and the Sub-Adviser shall be free

     other clients which may differ from the advice given, or the timing or
     nature of action taken, with respect to the Assets. Nothing in this
     Agreement shall be deemed to impose upon the Sub-Adviser any obligation to
     purchase or sell for the Portfolio any security or other property which
     Sub-Adviser purchases or sells for its own account or for the account of
     any other client.

(g)  The Sub-Adviser shall promptly notify the Adviser of any financial
     condition that is likely to impair the Sub-Adviser's ability to fulfill its

     responsible for voting and handling all proxies in relation to the
     securities held in the Portfolio. The Adviser shall instruct the custodian

     misdirected proxies to the Sub-Adviser.

     Services to be furnished by the Sub-Adviser under this Agreement may be
     furnished through the medium of any of the Sub-Adviser's partners, officers
     or employees.

                        INVESTMENT SUB-ADVISORY AGREEMENT
                       SEI INSTITUTIONAL INVESTMENTS TRUST


     AGREEMENT made this 14th day of June, 1996, between SEI Financial 
Management Corporation, (the "Adviser") and Firstar Investment Research & 
Management Company (the "Sub-Adviser").

     WHEREAS, SEI Institutional Investments Trust, a Massachusetts business 
trust (the "Trust") is registered as an open-end management investment 
company under the Investment Company Act of 1940, as amended (the "1940 
Act"); and

     WHEREAS, the Adviser has entered into an Investment Advisory Agreement 
dated June __, 1996 the "Advisory Agreement") with the Trust, pursuant to which 
the Adviser will act as investment adviser to the Core Fixed Income Portfolio 
(the "Portfolio"), which is a series of the Trust; and

     WHEREAS, the Adviser, with the approval of the Trust, desires to retain 
the Sub-Adviser to provide investment advisory services to the Adviser in 
connection with the management of the Portfolio, and the Sub-Adviser is 
willing to render such investment advisory services.

     NOW, THEREFORE, the parties hereto agree as follows:

1.   DUTIES OF THE SUB-ADVISER. Subject to supervision by the Adviser and the
     Trust's Board of Trustees, the Sub-Adviser shall manage all of the
     securities and other assets of the Portfolio entrusted to it hereunder (the
     "Assets"), including the purchase, retention and disposition of the Assets,
     in accordance with the Portfolio's investment objectives, policies and
     restrictions as stated in the Portfolio's prospectus and statement of
     additional information, as currently in effect and as amended or
     supplemented from time to time (referred to collectively as the
     "Prospectus"), and subject to the following:

(a)  The Sub-Adviser shall, in consultation with and subject to the direction of
     the Adviser, determine from time to time what Assets will be purchased,
     retained or sold by the Portfolio, and what portion of the Assets will be
     invested or held uninvested in cash.

(b)  In the performance of its duties and obligations under this Agreement, the
     Sub-Adviser shall act in conformity with the Trust's Declaration of Trust
     (as defined herein) and the Prospectus and with the instructions and
     directions of the Adviser and of the Board of Trustees of the Trust and
     will conform to and comply with the requirements of the 1940 Act, the
     Internal Revenue Code of 1986, and all other applicable federal and state
     laws and regulations, as each is amended from time to time.

(c)  The Sub-Adviser shall determine the Assets to be purchased or sold by the
     Portfolio as provided in subparagraph (a) and will place orders with or
     through such persons, brokers or dealers to carry out the policy with
     respect to brokerage set forth in the Portfolio's Registration Statement
     (as defined herein) and Prospectus or as the Board of Trustees or the
     Adviser may direct from time to time, in conformity with federal securities
     laws. In executing Portfolio transactions and selecting brokers or dealers,
     the Sub-Adviser will use its best efforts to seek on behalf of the
     Portfolio the best overall terms available. In assessing the best overall
     terms available for any transaction, the Sub-Adviser shall consider all
     factors that it deems relevant, including the breadth of the market in the
     security, the price of the security, the financial condition and execution
     capability of the broker or dealer, and the reasonableness of the
     commission, if any, both for the specific transaction and on a continuing
     basis. In evaluating the best overall terms available, and in selecting the
     broker-dealer to execute a particular transaction, the Sub-Adviser may also
     consider the brokerage and research services provided (as those terms are
     defined in Section 28(e) of the Securities Exchange Act of 1934).
     Consistent with any guidelines established by the Board of Trustees of the
     Trust, the Sub-Adviser is authorized to pay to a broker or dealer who
     provides such brokerage and research services a commission for executing a
     portfolio transaction for the Portfolio which is in excess of the amount of
     commission another broker or dealer would have charged for effecting that
     transaction if, but only if, the Sub-Adviser determines in good faith that
     such commission was reasonable in relation to the value of the brokerage
     and research services provided by such broker or dealer - - viewed in terms
     of that particular transaction or terms of the overall responsibilities of
     the Sub-Adviser to the Portfolio. In addition, the Sub-Adviser if
     authorized to allocate purchase and sale orders for securities to brokers
     or dealers (including brokers and dealers that are affiliated with the
     Adviser, Sub-Adviser or the Trust's principal underwriter) to take into
     account the sale of shares of the Trust if the Sub-Adviser believes that
     the quality of the transaction and the commission are comparable to what
     they would be with other qualified firms. In no instance, however, will the
     Portfolio's Assets be purchased



<PAGE>


     from or sold to the Adviser, Sub-Adviser, the Trust's principal
     underwriter, or any affiliated person of either the Trust, Adviser, the 
     Sub-Adviser or the principal underwriter, acting as principal in the 
     transaction, except to the extent permitted by the Securities and Exchange
     Commission ("SEC") and the 1940 Act.

(d)  The Sub-Adviser shall maintain all books and records with respect to
     transactions involving the Assets required by subparagraphs (b)(5), (6),
     (7), (9), (10) and (11) and paragraph (f) of Rule 31a-1 under the 1940 Act.
     The Sub-Adviser shall provide to the Adviser or the Board of Trustees such
     periodic and special reports, balance sheets or financial information, and
     such other information with regard to its affairs as the Adviser or Board
     of Trustees may reasonably request.

     The Sub-Adviser shall keep the books and records relating to the Assets
     required to be maintained by the Sub-Adviser under this Agreement and shall
     timely furnish to the Adviser all information relating to the Sub-Adviser's
     services under this Agreement needed by the Adviser to keep the other books
     and records of the Portfolio required by Rule 31a-1 under the 1940 Act. 
     The Sub-Adviser shall also furnish to the Adviser any other information
     relating to the Assets that is required to be filed by the Adviser or the
     Trust with the SEC or sent to shareholders under the 1940 Act (including
     the rules adopted thereunder) or any exemptive or other relief that the
     Adviser or the Trust obtains from the SEC. The Sub-Adviser agrees that all
     records that it maintains on behalf of the Portfolio are property of the
     Portfolio and the Sub-Adviser will surrender promptly to the Portfolio any
     of such records upon the Portfolio's request; provided, however, that the
     Sub-Adviser may retain a copy of such records. In addition, for the
     duration of this Agreement, the Sub-Adviser shall preserve for the periods
     prescribed by Rule 31a-2 under the 1940 Act any such records as are
     required to be maintained by it pursuant to this Agreement, and shall
     transfer said records to any successor sub-adviser upon the termination of
     this Agreement (or, if there is no successor sub-adviser to the Adviser).

(e)  The Sub-Adviser shall provide the Portfolio's custodian on each business
     day with information relating to all transactions concerning the
     Portfolio's Assets and shall provide the Adviser with such information upon
     request of the Adviser.

(f)  The investment management services provided by the Sub-Adviser under this
     Agreement are not to be deemed exclusive and the Sub-Adviser shall be free
     to render similar services to others, as long as such services do not 
     impair the services rendered to the Adviser or the Trust.

(g)  The Sub-Adviser shall promptly notify the Adviser of any financial
     condition that is likely to impair the Sub-Adviser's ability to fulfill its
     commitment under this Agreement.

(h)  The Sub-Adviser shall review all proxy solicitation materials and be
     responsible for voting and handling all proxies in relation to the
     securities held in the Portfolio. The Adviser shall instruct the custodian
     and other parties providing services to the Portfolio to promptly forward
     misdirected proxies to the Sub-Adviser.

     Services to be furnished by the Sub-Adviser under this Agreement may be
     furnished through the medium of any of the Sub-Adviser's partners, officers
     or employees.

2.   DUTIES OF THE ADVISER. The Adviser shall continue to have responsibility
     for all services to be provided to the Portfolio pursuant to the Advisory
     Agreement and shall oversee and review the Sub-Adviser's performance of its
     duties under this Agreement; provided, however, that in connection with its
     management of the Assets, nothing herein shall be construed to relieve the
     Sub-Adviser of responsibility for compliance with the Trust's Declaration
     of Trust (as defined herein), the Prospectus, the instructions and
     directions of the Board of Trustees of the Trust, the requirements of the
     1940 Act, the Internal Revenue Code of 1986, and all other applicable
     federal and state laws and regulations, as each is amended from time to
     time.

3.   DELIVERY OF DOCUMENTS. The Adviser has furnished the Sub-Adviser with
     copies properly certified or authenticated of each of the following
     documents:

(a)  The Trust's Agreement and Declaration of Trust, as filed with the Secretary
     of State of the Commonwealth of Massachusetts (such Agreement and
     Declaration of Trust, as in effect on the date of this Agreement and as
     amended from time to time, herein called the "Declaration of Trust");

     Agreement and as amended from time to time, are herein called the 
     "By-Laws");

(c)  Prospectus(es) of the Portfolio.

4.   COMPENSATION TO THE SUB-ADVISER. For the services to be provided by the
     Sub-Adviser pursuant to this Agreement, the Adviser will pay the
     Sub-Adviser, and the Sub-Adviser agrees to accept as full compensation
     therefor, a sub-advisory fee at the rate specified in the Schedule(s) which
     is attached hereto and made part of this Agreement. The fee will be
     calculated based on the average monthly market value of the Assets under
     the Sub-Adviser's management and will be paid to the Sub-Adviser monthly.
     Except as may otherwise be prohibited by law or regulation (including any
     then current SEC staff interpretation), the Sub-Adviser may, in its
     discretion and from time to time, waive a portion of its fee.

5.   INDEMNIFICATION. The Sub-Adviser shall indemnify and hold harmless the
     Adviser from and against any and all claims, losses, liabilities or damages
     (including reasonable attorney's fees and other related expenses) howsoever
     arising from or in connection with the performance of the Sub-Adviser's
     obligations under this Agreement; provided, however, that the Sub-Adviser's
     obligation under this Section 5 shall be reduced to the extent that the
     claim against, or the loss, liability or damage experienced by the Adviser,
     is caused by or is otherwise directly related to the Adviser's own willful
     misfeasance, bad faith or negligence, or to the reckless disregard of its
     duties under this Agreement.

6.   DURATION AND TERMINATION. This Agreement shall become effective upon its
     approval by the Trust's Board of Trustees and by the vote of a majority of
     the outstanding voting securities of the Portfolio.

     years from the date hereof only so long as continuance is specifically 
     approved at least annually in conformance with the 1940 Act; provided,

     vote of a majority of the outstanding voting securities of the Portfolio, 
     (b) by the Adviser at any time, without the payment of any penalty, on not
     more than 60 days' nor less than 30 days' written notice to the

                          INVESTMENT SUB-ADVISORY AGREEMENT
                         SEI INSTITUTIONAL INVESTMENTS TRUST
              
    AGREEMENT made this 14th day of June, 1996, by and among SEI Financial
Management Corporation, (the "Adviser") and IDS Advisory Group Inc. (the 
"Sub-Adviser"). 

    WHEREAS, SEI Institutional Investments Trust, a Massachusetts business
trust (the "Trust") is registered as an open-end management investment company
under the Investment Company Act of 1940, as amended (the "1940  Act"); and

    WHEREAS, the Adviser has entered into an Investment Advisory Agreement
dated June, 1996 (the "Advisory Agreement") with the Trust, pursuant to which
the Adviser will act as investment adviser to the Large Cap Portfolio (the
"Portfolio"), which is a series of the Trust; and

    WHEREAS, the Adviser, with the approval of the Trust, desires to retain the
Sub-Adviser to provide investment advisory services to the Adviser in connection
with the management of the Portfolio, and the Sub-Adviser is willing to render
such investment advisory services.

    NOW, THEREFORE, the parties hereto agree as follows:

1.  DUTIES OF THE SUB-ADVISER.  Subject to supervision by the Adviser and the
    Trust's Board of Trustees, the Sub-Adviser shall manage the investment of
    all of the securities and other assets of the Portfolio entrusted to it
    hereunder, including the purchase, retention and disposition of securities
    and other assets, in accordance with the Portfolio's investment objectives,
    policies and restrictions as stated in the Portfolio's prospectus and
    statement of additional information,  as currently in effect and as amended
    or supplemented from time to time (referred to collectively as the
    "Prospectus"), and subject to the following:

(a) The Sub-Adviser shall provide supervision of the Portfolio's investments
    and determine from time to time  what investments and securities will be
    purchased, retained or sold by the Portfolio, and what portion of the
    assets will be invested or held uninvested in cash.
    
(b) In the performance of its duties and obligations under this Agreement, the
    Sub-Adviser shall act in conformity with the Trust's Declaration of Trust
    (as defined herein) and the Prospectus and with the instructions and
    directions of the Adviser and of the Board of Trustees of the Trust and
    will conform to and comply with the requirements of the 1940 Act, the
    Internal Revenue Code of 1986, and all other applicable federal and state
    laws and regulations, as each is amended from time to time.
    
(c) The Sub-Adviser shall determine the securities to be purchased or sold by
    the Portfolio and will place orders with or through such persons, brokers
    or dealers to carry out the policy with respect to brokerage set forth in
    the Portfolio's Registration Statement and Prospectus or as the Board of
    Trustees or the Adviser may direct from time to time, in conformity with
    federal securities laws.  In executing Portfolio transactions and selecting
    brokers or dealers, the Sub-Adviser will use its best efforts to seek on
    behalf of the Portfolio the best overall terms available.  In assessing the
    best overall terms available for any transaction, the Sub-Adviser shall
    consider all factors that it deems relevant, including the breadth of the
    market in the security, the price of the security, the financial condition
    and execution capability of the 

                                           
<PAGE>

    broker or dealer, and the reasonableness of the commission, if any, both
    for the specific transaction and on a continuing basis.  In evaluating the
    best overall terms available, and in selecting the broker-dealer to execute
    a particular transaction the Sub-Adviser may also consider the brokerage
    and research services (as those terms are defined in Section 28(e) of the
    Securities Exchange Act of 1934) provided to the Portfolio and/or other
    accounts over which the Sub-Adviser or an affiliate of the Sub-Adviser may
    exercise investment discretion.  The Sub-Adviser is authorized, to pay to a
    broker or dealer who provides such brokerage and research services a
    commission for executing a portfolio transaction for any of the Portfolios
    which is in excess of the amount of commission another broker or dealer
    would have charged for effecting that transaction if, but only if, the 
    Sub-Adviser determines in good faith that such commission was reasonable in
    relation to the value of the brokerage and research services provided by
    such broker or dealer - - viewed in terms of that particular transaction or
    terms of the overall responsibilities of the Sub-Adviser to the Portfolio
    and other accounts.  In addition, the Sub-Adviser is authorized to allocate
    purchase and sale orders for portfolio securities to brokers or dealers
    (including brokers and dealers that are affiliated with the Sub-Adviser or
    the Trust's principal underwriter) to take into account the sale of shares
    of the Trust if the Sub-Adviser believes that the quality of the
    transaction and the commission are comparable to what they would be with
    other qualified firms.  In no instance, however, will any Portfolio's
    securities be purchased from or sold to the Sub-Adviser, the Trust's
    principal underwriter, or any affiliated person of either the Trust, the
    Sub-Adviser or the principal underwriter, acting as principal in the
    transaction, except to the extent permitted by the Securities and Exchange
    Commission and the 1940 Act.
     
(d) The Sub-Adviser shall maintain all books and records with respect to the
    Portfolio's portfolio transactions required by subparagraphs (b)(5), (6),
    (7), (9), (10) and (11) and paragraph (f) of Rule 31a-1 under the 1940 Act
    and shall render to the Adviser or Board of Trustees such periodic and
    special reports as the Adviser or Board of Trustees may reasonably request. 
    Upon reasonable request and for purposes of a Securities and Exchange
    Commission or other regulatory inspection, the Adviser will furnish 
    Sub-Adviser with information maintained by it as Adviser to the Portfolio.
    
    The Sub-Adviser shall keep the Portfolio's books and records required to be
    maintained by the Sub-Adviser by this Agreement and shall timely furnish to
    the Adviser all information relating to the Sub-Adviser's services under
    this Agreement needed by the Adviser to keep the other books and records of
    the Portfolio required by Rule 31a-1 under the 1940 Act.  The Sub-Adviser
    shall also furnish to the Adviser any other information that is required to
    be filed by the Adviser or the Trust with the Securities and Exchange
    Commission ("SEC") or sent to shareholders under the 1940 Act (including
    the rules adopted thereunder) or any exemptive or other relief that the
    Adviser or the Trust obtains from the SEC.  The Sub-Adviser agrees that all
    records that it maintains on behalf of the Portfolio are property of the
    Portfolio and the Sub-Adviser will surrender promptly to the Portfolio any
    of such records upon the Portfolio's request; provided, however, that the
    Sub-Adviser may retain a copy of such records.  In addition, for the
    duration of this Agreement, the  Sub-Adviser shall preserve for the periods
    prescribed by Rule  31a-2 under the 1940 Act any such records as are
    required to be maintained by it pursuant to this Agreement, and shall
    transfer said records to any successor Sub-Adviser upon the termination of
    his Agreement (or, if there is no successor 

                                          2
<PAGE>
    Sub-Adviser, to the Adviser).
    
(e) The Sub-Adviser shall provide the Portfolio's custodian on each business
    day with information relating to all transactions concerning the
    Portfolio's assets and shall provide the Adviser with such information upon
    request of the Adviser.
    
(f) The investment management services provided by the Sub-Adviser under this
    Agreement are not to be deemed exclusive and the Sub-Adviser shall be free
    to render similar services to others, as long as such services do not
    impair the services rendered to the Adviser or the Trust.
    
(g) The Sub-Adviser shall promptly notify the Adviser of any financial
    condition that is likely to impair the Sub-Adviser's ability to fulfill its
    commitment under this Agreement.
 
(h) The Sub-Adviser shall review all proxy solicitation materials and be
    responsible for voting and handling all proxies in relation to the
    securities held in the Portfolio.  The Adviser shall instruct custodian and
    other parties providing services to the Portfolio to promptly forward
    misdirected proxies to Sub-Adviser.

    Services to be furnished by the Sub-Adviser under this Agreement may be
    furnished through the medium of any of the Sub-Adviser's partners, officers
    or employees.

2.  DUTIES OF THE ADVISER.  The Adviser shall continue to have responsibility
    for all services to be provided to the Portfolio pursuant to the Advisory
    Agreement and shall oversee and review the Sub-Adviser's performance of its
    duties under this Agreement; provided, however, that nothing herein shall
    be construed to relieve the Sub-Adviser of responsibility for compliance
    with the Portfolio's investment objectives, policies, and restrictions, as
    provided in Section 1 hereunder.

3.  DELIVERY OF DOCUMENTS.  The Adviser has furnished the Sub-Adviser with
    copies properly certified or authenticated of each of the following
    documents:

(a) The Trust's Agreement and Declaration of Trust, as filed with the Secretary
    of State of the Commonwealth of Massachusetts (such Agreement and
    Declaration of Trust, as in effect on the date of this Agreement and as
    amended from time to time, herein called the "Declaration of Trust");
    
(b) By-Laws of the Trust (such By-Laws, as in effect on the date of this
    Agreement and as amended from time to time, are herein called the 
    "By-Laws");
    
(c) Prospectus(es) of the Portfolio.
    
4.  COMPENSATION TO THE SUB-ADVISER.  For the services to be provided by the
    Sub-Adviser pursuant to this Agreement, the Adviser will pay the 
    Sub-Adviser, and the Sub-Adviser agrees to accept as full compensation
    therefor, a sub-advisory fee at the rate specified in the Schedule(s) which
    is attached hereto and made part of this Agreement.  The fee will be 


                                          3
<PAGE>

    calculated based on the average monthly market value of investments under
    management and will be paid to the Sub-Adviser monthly.  The Sub-Adviser
    may, in its discretion and from time to time, waive a portion of its fee.

5.  LIMITATION OF LIABILITY OF THE SUB-ADVISER.  The Sub-Adviser shall not be
    liable for any error of judgment or for any loss suffered by the Adviser in
    connection with the performance of the Sub-Adviser's obligations under this
    Agreement, except a loss resulting from a breach of fiduciary duty with
    respect to the receipt of compensation for services (in which case any
    award of damages shall be limited to the period and the amount set forth in
    Section 36(b)(3) of the 1940 Act), or a loss resulting from willful
    misfeasance, bad faith or negligence on the Sub-Adviser's part in the
    performance of its duties or from reckless disregard of its obligations and
    duties under this Agreement, except as may otherwise be provided under
    provisions of applicable state law which cannot be waived or modified
    hereby.

6.  REPORTS.  During the term of this Agreement, the Adviser agrees to furnish
    the Sub-Adviser at its principal office all prospectuses, proxy statements,
    reports to stockholders, sales literature or other materials prepared for
    distribution to stockholders of the Portfolios, the Trust or the public
    that refer to the Sub-Adviser or its clients in any way prior to use
    thereof and not to use material if the Sub-Adviser reasonably objects in
    writing within five business days (or such other period as may be mutually
    agreed) after receipt thereof.  The Sub-Adviser's right to object to such
    materials is limited to the portions of such materials that expressly
    relate to the Sub-Adviser, its services and its clients.  The Adviser
    agrees to use its reasonable best efforts to ensure that materials prepared
    by its employees or agents or its affiliates that refer to the Sub-Adviser
    or its clients in any way are consistent with those materials previously
    approved by the Sub-Adviser as referenced in the first sentence of this
    paragraph.  Sales literature may be furnished to the Sub-Adviser by first
    class or overnight mail, facsimile transmission equipment or hand delivery.

7.  INDEMNIFICATION.  The Sub-Adviser shall indemnify and hold harmless the
    Adviser from and against any and all claims, losses, liabilities or damages
    (including reasonable attorney's fees and other related expenses) howsoever
    arising from or in connection with the performance by the Sub-Adviser of
    its duties under this Agreement; provided, however, that the Sub-Adviser
    shall not be required to indemnify or otherwise hold the Adviser harmless
    under this Section 7 where the claim against, or the loss, liability or
    damage experienced by the Adviser, is caused by or is otherwise directly
    related to the Adviser's own willful misfeasance, bad faith or negligence,
    or to the reckless disregard of its duties under this Agreement. 

    The Adviser shall indemnify and hold harmless the Sub-Adviser from and
    against any and all claims, losses, liabilities or damages (including
    reasonable attorney's fees and other related expenses) howsoever arising
    from or in connection with the performance by the Adviser of its duties
    under this Agreement; provided, however, that the Adviser shall not be
    required to indemnify  or otherwise hold the Sub-Adviser harmless under
    this Section 7 where the claim against, or the loss, liability or damage
    experienced by the Sub-Adviser, is caused by or is otherwise directly
    related to the Sub-Adviser's own willful misfeasance, bad faith or
    negligence, or to the reckless disregard of its duties under this
    Agreement.

<PAGE>

8.  DURATION AND TERMINATION.  This Agreement shall become effective upon its
    approval by the Trust's Board of Trustees and by the vote of a majority of
    the outstanding voting securities of the Portfolio; provided, however, that
    at any time the Adviser shall have obtained exemptive relief from the SEC
    permitting it to engage a Sub-Adviser without first obtaining approval of
    the Agreement from a majority of the outstanding voting securities of the
    Portfolio(s) involved, the Agreement shall become effective upon its
    approval by the Trust's Board of Trustees.  Any Sub-Adviser so selected and
    approved shall be without the protection accorded by shareholder approval
    of an investment adviser's receipt of compensation under Section 36(b) of
    the 1940 Act.

    This Agreement shall continue in effect for a period of more than two years
    from the date hereof only so long as continuance is specifically approved
    at least annually in conformance with the 1940 Act; provided, however, that
    this Agreement may be terminated with respect to the Portfolio (a) by the
    Portfolio at any time, without the payment of any penalty, by the vote of a
    majority of Trustees of the Trust or by the vote of a majority of the
    outstanding voting securities of such Portfolio, (b) by the Adviser at any
    time, without the payment of any penalty, on not more than 60 days' nor
    less than 30 days' written notice to the other party, or (c) by the 
    Sub-Adviser at any time, without the payment of any penalty, on 90 days'
    written notice to the other party.  This Agreement shall terminate
    automatically and immediately in the event of its assignment, or in the
    event of a termination of the Adviser's agreement with the Trust.  As used
    in this Section 8, the terms "assignment" and "vote of a majority of the
    outstanding voting securities" shall have the respective meanings set forth
    in the 1940 Act and the rules and regulations thereunder, subject to such
    exceptions as may be granted by the Commission under the 1940 Act.

9.  GOVERNING LAW.  This Agreement shall be governed by the internal laws of
    the Commonwealth of Massachusetts, without regard to conflict of law
    principles; provided, however, that nothing herein shall be construed as
    being inconsistent with the 1940 Act.

10. SEVERABILITY.  Should any part of this Agreement be held invalid by a court
    decision, statute, rule or otherwise, the remainder of this Agreement shall
    not be affected thereby.  This Agreement shall be binding upon and shall
    inure to the benefit of the parties hereto and their respective successors.

11. NOTICE.  Any notice, advice or report to be given pursuant to this
    Agreement shall be deemed sufficient if delivered or mailed by registered,
    certified or overnight mail, postage prepaid addressed by the party giving
    notice to the other party at the last address furnished by the other party:

     AGREEMENT made this 14th day of June, 1996, by and among SEI Financial
Management Corporation, (the "Adviser") and LSV Asset Management (the
"Sub-Adviser").

     WHEREAS, SEI Institutional Investments Trust, a Massachusetts business
trust (the "Trust") is registered as an open-end management investment company
under the Investment Company Act of 1940, as amended (the "1940 Act"); and

     WHEREAS, the Adviser has entered into an Investment Advisory Agreement
dated June 14, 1996 (the "Advisory Agreement") with the Trust, pursuant to which

     WHEREAS, the Adviser, with the approval of the Trust, desires to retain the

with the management of the Portfolio, and the Sub-Adviser is willing to render
such investment advisory services.

     NOW THEREFORE, the parties hereto agree as follows:

1.   DUTIES OF THE SUB-ADVISER. Subject to supervision by the Adviser and the
     Trust's Board of Trustees, the Sub-Adviser shall manage the investment
     operations of the Portfolio and the composition of the Portfolio, including
     the purchase, retention and disposition of securities and other assets, in
     accordance with the Portfolio's investment objectives, policies and
     restrictions as stated in the Portfolio's prospectus and statement of
     additional information, as currently in effect and as amended or
     supplemented from time to time (referred to collectively as the
     "Prospectus"), and subject to the following:

(a)  The Sub-Adviser shall provide supervision of the Portfolio's investments
     and determine from time to time what investments and securities will be
     purchased, retained or sold by the Portfolio, and what portion of the 
     assets will be invested or held uninvested in cash.

(b)  In the performance of its duties and obligations under this Agreement, the

     available.  In assessing the best overall terms available for any 
     transaction, the Sub-Adviser shall consider all factors that it deems 
     relevant, including the breadth of the market in the security, the price of
     the security, the financial condition and execution capability of the 
     broker or dealer, and the reasonableness of the commission, if any, both
     for the specific transaction and on a continuing basis. In evaluating the
     best overall terms available, and in selecting the broker-dealer to execute
     a particular transaction the Sub-Adviser may also consider the brokerage
     and research services (as those terms are defined in Section 28(e) of the
     Securities Exchange Act of 1934)
<PAGE>


     provided to the Portfolio and/or other accounts over which the Sub-Adviser
     or an affiliate of the Sub-Adviser may exercise investment discretion. The
     Sub-Adviser is authorized, subject to the prior approval of the Trust's
     Board of Trustees, to pay to a broker or dealer who provides such brokerage
     and research services a commission for executing a portfolio transaction
     for any of the Portfolios which is in excess of the amount of commission
     another broker or dealer would have charged for effecting that transaction
     if, but only if, the Sub-Adviser determines in good faith that such
     commission was reasonable in relation to the value of the brokerage and
     research services provided by such broker or dealer -- in terms of that
     particular transaction or terms of the overall responsibilities of the
     Sub-Adviser to the Portfolio. In addition, the Sub-Adviser if authorized to
     allocate purchase and sale orders for portfolio securities to brokers or
     dealers (including brokers and dealers that are affiliated with the 
     Sub-Adviser or the Trust's principal underwriter) to take into account the 
     sale of shares of the Trust if the Sub-Adviser believes that the quality 
     of the transaction and the commission are comparable to what they would be 
     with other qualified firms. In no instance, however, will any Portfolio's
     securities be purchased from or sold to the Sub-Adviser, the Trust's
     principal underwriter, or any affiliated person of either the Trust, the
     Sub-Adviser or the principal underwriter, acting as principal in the
     transaction, except to the extent permitted by the Securities and Exchange
     Commission and the 1940 Act.

(d)  The Sub-Adviser shall maintain all books and records with respect to the
     Portfolio's portfolio transactions required by subparagraphs (b)(5), (6),
     (7), (9), (10) and (11) and paragraph (f) of Rule 31a-1 under the 1940 Act
     and shall render to the Adviser or Board of Trustees such periodic and
     special reports as the Adviser or Board of Trustees may reasonably request.

     The Sub-Adviser shall keep the Portfolio's books and records required to be
     maintained by the Sub-Adviser of this Agreement and shall timely furnish to
     the Adviser all information relating to the Sub-Adviser's services under
     this Agreement needed by the Adviser to keep the other books and records of
     the Portfolio required by Rule 31a-1 under the 1940 Act. The Sub-Adviser
     shall also furnish to the Adviser any other information that is required to
     be filled by the Adviser or the Trust with the Securities and Exchange
     Commission ("SEC") or sent to shareholders under the 1940 Act (including
     the rules adopted thereunder) or any exemptive or other relief that the
     Adviser or the Trust obtains from the SEC. The Sub-Adviser agrees that all
     records that it maintains on behalf of the Portfolio are property of the
     Portfolio and the Sub-Adviser will surrender promptly to the Portfolio any
     of such records upon the Portfolio's request; provided, however, that the
     Sub-Adviser may retain a copy of such records. In addition, for the
     duration of this Agreement, the Sub-Adviser shall preserve for the periods
     prescribed by Rule 31a-2 under the 1940 Act any such records as are
     required to be maintained by it pursuant to this Agreement, and shall
     transfer said records to any successor Sub-Adviser upon the termination of
     his Agreement (or, if there is no successor Sub-Adviser, to the Adviser).

(e)  The Sub-Adviser shall provide the Portfolio's custodian on each business
     day with information relating to all transactions concerning the
     Portfolio's assets and shall provide the Adviser with such information upon
     request of the Adviser.

(f)  The investment management services provided by the Sub-Adviser under this
     Agreement are not to be deemed exclusive and the Sub-Adviser shall be free
     to render similar services to others, as long as such services do not
     impair the services rendered to the Adviser or the Trust.

(g)  The Sub-Adviser shall promptly notify the Adviser of any financial
     condition that is likely to impair the Sub-Adviser's ability to fulfill its
     commitment under this Agreement.

     Services to be furnished by the Sub-Adviser under this Agreement may be
     furnished through the medium of any of the Sub-Adviser's partners, officers
     or employees.

2.   DUTIES OF THE ADVISER. The Adviser shall continue to have responsibility
     for all services to be provided to the Portfolio pursuant to the Advisory
     Agreement and shall oversee and review the Sub-Adviser's performance of its
     duties under this Agreement; provided, however, that nothing herein shall
     be construed to relieve the Sub-Adviser of responsibility for compliance
     with the Portfolio's investment objectives, policies, and restrictions, as
     provided in Section 1 hereunder.

3.   DELIVERY OF DOCUMENTS. The Adviser has furnished the Sub-Adviser with
     copies properly certified or authenticated of each of the following
     documents:

(a)  The Trust's Agreement and Declaration of Trust, as filed with the Secretary
     of State of the Commonwealth of Massachusetts (such Agreement and
     Declaration of Trust, as in effect on the date of this Agreement and as
     amended from time to time, herein called the "Declaration of Trust");

(b)  By-Laws of the Trust (such By-Laws, as in effect on the date of this
     Agreement and as amended from time to time, are herein called the
     "By-Laws");

(c)  Prospectus(es) of the Portfolio.

4.   COMPENSATION TO THE SUB-ADVISER. For the services to be provided by the
     Sub-Adviser pursuant to this Agreement, the Adviser will pay the
     Sub-Adviser, and the Sub-Adviser agrees to accept as full compensation
     therefor, a sub-advisory fee at the rate specified in the Schedule(s) which
     is attached hereto and made part of this Agreement. The fee will be
     calculated based on the average monthly market value of investments under
     management and will be paid to the Sub-Adviser monthly.  The Sub-Adviser
     may, in its discretion and from time to time, waive a portion of its fee.

5.   LIMITATION OF LIABILITY OF THE SUB-ADVISER. The Sub-Adviser shall not be
     liable for any error of judgment or for any loss suffered by the Adviser in
     connection with performance of its obligations under this Agreement, except
     a loss resulting from a breach of fiduciary duty with respect to the
     receipt of compensation for services (in which case any award of damages
     shall be limited to the period and the amount set forth in Section 36(b)(3)
     of the 1940 Act), or a loss resulting from willful misfeasance, bad faith
     or negligence on the Sub-Adviser's part in the performance of its duties or
     from reckless disregard of its obligations and duties under this Agreement,
     except as may otherwise be provided under provisions of applicable state
     law which cannot be waived or modified hereby.

6.   REPORTS. During the term of this Agreement, the Adviser agrees to furnish
     the Sub-Adviser at its principal office all prospectuses, proxy statements,
     reports to stockholders, sales literature or other materials prepared for
     distribution to stockholders of the Portfolios, the Trust or the public
     that refer to the Sub-Adviser or its clients in any way prior to use
     thereof and not to use material if the Sub-Adviser reasonably objects in
     writing within five business days (or such other period as may be mutually
     agreed) after receipt thereof. The Sub-Adviser's right to object to such
     materials is limited to the portions of such materials that expressly
     relate to the Sub-Adviser, its services and its clients. The Adviser agrees
     to use its reasonable best efforts to ensure that materials prepared by its
     employees or agents or its affiliates that refer to the Sub-Adviser or its
     clients in any way are consistent with those materials previously approved
     by the Sub-Adviser as referenced in the first sentence of this paragraph.
     Sales literature may be furnished to the Sub-Adviser by first class or
     overnight mail, facsimile transmission equipment or hand delivery.

7.   INDEMNIFICATION. The Sub-Adviser shall indemnify and hold harmless the
     Adviser from and against any and all claims, losses, liabilities or damages
     (including reasonable attorney's fees and other related
<PAGE>


     expenses) howsoever arising from or in connection with this Agreement or
     the performance by the Sub-Adviser of its duties hereunder; provided, 
     however, that the Sub-Adviser shall not be required to indemnify or 
     otherwise hold the Adviser harmless under this Section 7 where the claim
     against, or the loss, liability or damage experienced by the Adviser, is 
     caused by or is otherwise directly related to the Adviser's own willful
     misfeasance, bad faith or negligence, or to the reckless disregard of its
     duties under this Agreement.

8.   DURATION AND TERMINATION. This Agreement shall become effective upon its
     approval by the Trust's Board of Trustees and by the vote of a majority of
     the outstanding voting securities of the Portfolio; provided, however, that
     at any time the Adviser shall have obtained exemptive relief from the SEC
     permitting it to engage a Sub-Adviser without first obtaining approval of
     the Agreement from a majority of the outstanding voting securities of the
     Portfolio(s) involved, the Agreement shall become effective upon its
     approval by the Trust's Board of Trustees. Any Sub-Adviser so selected and
     approved shall be without the protection accorded by shareholder approval
     of an investment adviser's receipt of compensation under Section 36(b) of
     the 1940 Act. 

     This Agreement shall continue in effect for a period of more
     than two years from the date hereof only so long as continuance is
     specifically approved at least annually in conformance with the 1940 Act;
     provided, however, that this Agreement may be terminated with respect to
     the Portfolio (a) by the Portfolio at any time, without the payment of any
     penalty, by the vote of a majority of Trustees of the Trust or by the vote
     of a majority of the outstanding voting securities of such Portfolio, (b)
     by the Adviser at any time, without the payment of any penalty, on not more
     than 60 days' nor less than 30 days' written notice to the other party, or
     (c) by the Sub-Adviser at any time, without the payment of any penalty, on
     90 days' written notice to the other party. This Agreement shall terminate
     automatically and immediately in the event of its assignment, or in the
     event of a termination of the Adviser's agreement with the Trust.   As
     used in this Section 8, the terms "assignment" and "vote of a majority of 
     the outstanding voting securities" shall have the respective meanings set 
     forth in the 1940 Act and the rules and regulations thereunder, subject to
     such exceptions as may be granted by the Commission under the 1940 Act.

9.   GOVERNING LAW. This Agreement shall be governed by the internal laws of the
     Commonwealth of Massachusetts, without regard to conflict of law
     principles; provided, however, that nothing herein shall be construed as
     being inconsistent with the 1940 Act.

10.  SEVERABILITY. Should any part of this Agreement be held invalid by a court
     decision, statute, rule or otherwise, the remainder of this Agreement shall
     not be affected thereby. This Agreement shall be binding upon and shall
     inure to the benefit of the parties hereto and their respective successors.

11.  NOTICE: Any notice, advice or report to be given pursuant to this Agreement
     shall be deemed sufficient if delivered or mailed by registered, certified
     or overnight mail, postage prepaid addressed by the party giving notice to
     the other party at the last address furnished by the other party:

                         SEI INSTITUTIONAL INVESTMENTS TRUST

    AGREEMENT made this 14 day of June, 1996, by and among SEI Financial
Management Corporation, (the "Adviser") and Mellon Equity Associates (the
"Sub-Adviser").

    WHEREAS, SEI Institutional Investments Trust, a Massachusetts business
trust (the "Trust") is registered as an open-end management investment company
under the Investment Company Act of 1940, as amended (the "1940 Act"); and

    WHEREAS, the Adviser has entered into an Investment Advisory Agreement
dated June 14, 1996 (the "Advisory Agreement") with the Trust, pursuant to which
the Adviser will act as investment adviser to the Large Cap Portfolio (the
"Portfolio"), which is a series of the Trust; and

    WHEREAS, the Adviser, with the approval of the Trust, desires to retain the
Sub-Adviser to provide investment advisory services to the Adviser in connection
with the management of the Portfolio, and the Sub-Adviser is willing to render
such investment advisory services.

    NOW, THEREFORE, the parties hereto agree as follows:

1.  DUTIES OF THE SUB-ADVISER. Subject to supervision by the Adviser and the
    Trust's Board of Trustees, the Sub-Adviser shall manage the investment
    operations of the Portfolio and the composition of the Portfolio, including
    the purchase, retention and disposition of securities and other assets, in
    accordance with the Portfolio's investment objectives, policies and
    restrictions as stated in the Portfolio's prospectus and statement of
    additional information, as currently in effect and as amended or
    supplemented from time to time (referred to collectively as the
    "Prospectus"), and subject to the following:

(a) The Sub-Adviser shall provide supervision of the Portfolio's investments
    and determine from time to time what investments and securities will be
    purchased, retained or sold by the Portfolio, and what portion of the
    assets will be invested or held uninvested in cash.

(b) In the performance of its duties and obligations under this Agreement, the
    Sub-Adviser shall act in conformity with the Trust's Declaration of Trust
    (as defined herein) and the Prospectus and with the instructions and
    directions of the Adviser and of the Board of Trustees of the Trust and
    will conform to and comply with the requirements of the 1940 Act, the
    Internal Revenue Code of 1986, and all other applicable federal and state
    laws and regulations, as each is amended from time to time.

(c) The Sub-Adviser shall determine the securities to be purchased or sold by
    the Portfolio and will place orders with or through such persons, brokers
    or dealers to carry out the policy with respect to brokerage set forth in
    the Portfolio's Registration Statement and Prospectus or as the Board of
    Trustees or the Adviser may direct from time to time, in conformity with
    federal securities laws. In executing Portfolio transactions and selecting
    brokers or dealers, the Sub-Adviser will use its best efforts to seek on
    behalf of the Portfolio the best overall terms available. In assessing the
    best overall terms available for any transaction, the Sub-Adviser shall
    consider all factors that it deems relevant, which may include the breadth
    of the market in the security, the price of the security, the financial
    condition and execution capability of the broker or dealer, and the
    reasonableness of the commission, if any, both for the specific transaction
    and on a continuing basis. In evaluating the best overall terms available,
    and in selecting the broker-dealer to execute a particular transaction the
    Sub-Adviser may also consider the brokerage and research services (as those
    terms are defined in Section 28(e) of the Securities Exchange Act of 1934)
    provided to the



<PAGE>

    Portfolio and/or other accounts over which the Sub-Adviser or an affiliate
    of the Sub-Adviser may exercise investment discretion. The Sub-Adviser is
    authorized, subject to the prior approval of the Trust's Board of Trustees,
    to pay to a broker or dealer who provides such brokerage and research
    services a commission for executing a portfolio transaction for any of the
    Portfolios which is in excess of the amount of commission another broker or
    dealer would have charged for effecting that transaction if, but only it,
    the Sub-Adviser determines in good faith that such commission was
    reasonable in relation to the value of the brokerage and research services
    provided by such broker or dealer -- viewed in terms of that particular
    transaction or terms of the overall responsibilities of the Sub-Adviser to
    the Portfolio. In addition, the Sub-Adviser is authorized to allocate
    purchase and sale orders for portfolio securities to brokers or dealers
    (including brokers and dealers that are affiliated with the Sub-Adviser or
    the Trust's principal underwriter) to take into account the sale of shares
    of the Trust if the Sub-Adviser believes that the quality of the
    transaction and the commission are comparable to what they would be with
    other qualified firms. In no instance, however, will the Portfolio's
    securities be purchased from or sold to the Sub-Adviser, the Trust's
    principal underwriter, or any affiliated person of either the Trust, the
    Sub-Adviser or the principal underwriter, acting as principal in the
    transaction, except to the extent permitted by the Securities and Exchange
    Commission and the 1940 Act.

(d) The Sub-Adviser shall maintain all books and records with respect to the
    Portfolio's portfolio transactions required by subparagraphs (b)(5), (6),
    (7), (9), (10) and (11) and paragraph (f) of Rule 31a-1 under the 1940 Act
    and shall render to the Adviser or Board of Trustees such periodic and
    special reports as the Adviser or Board of Trustees may reasonably request.

    The Sub-Adviser shall keep the Portfolio's books and records required to be
    maintained by the Sub-Adviser of this Agreement and shall timely furnish to
    the Adviser all information relating to the Sub-Adviser's services under
    this Agreement needed by the Adviser to keep the other books and records of
    the Portfolio required by Rule 31a-1 under the 1940 Act. The Sub-Adviser
    shall also furnish to the Adviser any other information that is required to
    be filed by the Adviser or the Trust with the Securities and Exchange
    Commission ("SEC") or sent to shareholders under the 1940 Act (including
    the rules adopted thereunder) or any exemptive or other relief that the
    Adviser or the Trust obtains from the SEC. The Sub-Adviser agrees that all
    records that it maintains on behalf of the Portfolio are property of the
    Portfolio and the Sub-Adviser will surrender promptly to the Portfolio any
    of such records upon the Portfolio's request; provided, however, that the
    Sub-Adviser may retain a copy of such records. In addition, for the
    duration of this Agreement, the Sub-Adviser shall preserve for the periods
    prescribed by Rule 3la-2 under the 1940 Act any such records as are
    required to be maintained by it pursuant to this Agreement, and shall
    transfer said records to any successor Sub-Adviser upon the termination of
    this Agreement (or, if there is no successor Sub-Adviser, to the Adviser).

(e) The Sub-Adviser shall provide the Portfolio's custodian on each business
    day with information relating to all transactions concerning the
    Portfolio's assets and shall provide the Adviser with such information upon
    request of the Adviser.

(f) The investment management services provided by the Sub-Adviser under this
    Agreement are not to be deemed exclusive and the Sub-Adviser shall be free
    to render similar services to others, as long as such services do not
    impair the services rendered to the Adviser or the Trust.

(g) The Sub-Adviser shall promptly notify the Adviser of any financial
    condition that is likely to impair the Sub-Adviser's ability to fulfill its
    commitment under this Agreement.

<PAGE>

    Services to be furnished by the Sub-Adviser under this Agreement may be
    furnished through the medium of any of the Sub-Adviser's partners, officers 
    or employees.

2.  DUTIES OF THE ADVISER. The Adviser shall continue to have responsibility
    for all services to be provided to the Portfolio pursuant to the Advisory
    Agreement and shall oversee and review the Sub-Adviser's performance of its
    duties under this Agreement; provided, however, that nothing herein shall
    be construed to relieve the Sub-Adviser of responsibility for compliance
    with the Portfolio's investment objectives, policies, and restrictions, as
    provided in Section 1 hereunder. The Adviser hereby covenants to promptly
    provide the Sub-Adviser with copies of any amendment or supplement to the
    Portfolio's Registration Statement as well as all applicable trading
    guidelines and procedures established for the Portfolio.

3.  DELIVERY OF DOCUMENTS. The Adviser has furnished the Sub-Adviser with
    copies properly certified or authenticated of each of the following
    documents:

(a) The Trust's Agreement and Declaration of Trust, as filed with the Secretary
    of State of the Commonwealth of Massachusetts (such Agreement and
    Declaration of Trust, as in effect on the date of this Agreement and as
    amended from time to time, herein called the "Declaration of Trust");

(b) By-Laws of the Trust (such By-Laws, as in effect on the date of this
    Agreement and as amended from time to time, are herein called the "By-
    Laws");

(c) Prospectus(es) of the Portfolio.

(d) The Adviser hereby covenants to promptly furnish the Sub-Adviser with
    copies of any amendments or supplements to such documents.

4.  COMPENSATION TO THE SUB-ADVISER. For the services to be provided by the
    Sub-Adviser pursuant to this Agreement, the Adviser will pay the
    Sub-Adviser, and the Sub-Adviser agrees to accept as full compensation
    therefor, a sub-advisory fee at the rate specified in Schedule A which is
    attached hereto and made part of this Agreement. The fee will be calculated
    based on the average monthly market value of investments under management
    and will be paid to the Sub-Adviser monthly. The Sub-Adviser may, in its
    discretion and from time to time, waive a portion of its fee.

5.  LIMITATION OF LIABILITY OF THE SUB-ADVISER. The Sub-Adviser shall not be
    liable for any error of judgment or for any loss suffered by the Adviser in
    connection with performance of its obligations under this Agreement, except
    a loss resulting from a breach of fiduciary duty with respect to the
    receipt of compensation for services (in which case any award of damages
    shall be limited to the period and the amount set forth in Section 36(b)(3)
    of the 1940 Act), or a loss resulting from willful misfeasance, bad faith
    or negligence on the Sub-Adviser's part in the performance of its duties or
    from reckless disregard of its obligations and duties under this Agreement,
    except as may otherwise be provided under provisions of applicable state
    law which cannot be waived or modified hereby.

6.  REPORTS.  During the term of this Agreement, the Adviser agrees to furnish
    the Sub-Adviser at its principal office all prospectuses, proxy statements,
    reports to stockholders, sales literature or other materials prepared for
    distribution to stockholders of the Portfolios, the Trust or the public
    that refer to the Sub-Adviser or its clients in any way prior to use
    thereof and not to use material

<PAGE>

    if the Sub-Adviser reasonably objects in writing within five business days
    (or such other period as may be mutually agreed) after receipt thereof. The
    Sub-Adviser's right to object to such materials is limited to the portions
    of such materials that expressly relate to the Sub-Adviser, its services
    and its clients. The Adviser agrees to use its reasonable best efforts to
    ensure that materials prepared by its employees or agents or its affiliates
    that refer to the Sub-Adviser or its clients in any way are consistent
    with those materials previously approved by the Sub-Adviser as referenced
    in the first sentence of this paragraph. Sales literature may be furnished
    to the Sub-Adviser by first class or overnight mail, facsimile transmission
    equipment or hand delivery.

7.  INDEMNIFICATION.  The Sub-Adviser shall indemnify and hold harmless the
    Adviser from and against any, and all claims, losses, liabilities or
    damages (including reasonable attorney's fees and other related expenses)
    howsoever arising from or in connection with the performance by the
    Sub-Adviser of its duties under this Agreement; provided, however, that the
    Sub-Adviser shall not be required to indemnify or otherwise hold the
    Adviser harmless under this Section 7 where the claim against, or the loss,
    liability or damage experienced by the Adviser, is caused by or is
    otherwise directly related to the Adviser's own willful misfeasance, bad
    faith or negligence, or to the reckless disregard of its duties under this
    Agreement.

    The Adviser shall indemnify and hold harmless the Sub-Adviser from and
    against any and all claims, losses, liabilities or damages (including
    reasonable attorney's fees and other related expenses) howsoever arising
    from or in connection with the performance by the Adviser of its duties
    under this Agreement; provided, however, that the Adviser shall not be
    required to indemnify or otherwise hold the Sub-Adviser harmless under this
    Section 7 where the claim against, or the loss, liability or damage
    experienced by the Sub-Adviser, is caused by or is otherwise directly
    related to the Sub-Adviser's own willful misfeasance, bad faith or
    negligence, or to the reckless disregard of its duties under this
    Agreement.

8.  DURATION AND TERMINATION. This Agreement shall become effective upon its
    approval by the Trust's Board of Trustees and by the vote of a majority of
    the outstanding voting securities of the Portfolio; provided, however, that
    at any time the Adviser shall have obtained exemptive relief from the SEC
    permitting it to engage a Sub-Adviser without first obtaining approval of
    the Agreement from a majority of the outstanding voting securities of the
    Portfolio involved, the Agreement shall become effective upon its approval
    by the Trust's Board of Trustees. Any Sub-Adviser so selected and approved
    shall be without the protection accorded by shareholder approval of an
    investment adviser's receipt of compensation under Section 36(b) of the
    1940 Act.

    This Agreement shall continue in effect for a period of more than two years
    from the date hereof only so long as continuance is specifically approved
    at least annually in conformance with the 1940 Act; provided, however, that
    this Agreement may be terminated with respect to the Portfolio (a) by the
    Portfolio at any time, without the payment of any penalty, by the vote of a
    majority of Trustees of the Trust or by the vote of a majority of the
    outstanding voting securities of such Portfolio, (b) by the Adviser at any
    time, without the payment of any penalty, on not more than 60 days' nor
    less than 30 days' written notice to the other party, or (c) by the
    Sub-Adviser at any time, without the payment of any penalty, on 90 days'
    written notice to the other party. This Agreement shall terminate
    automatically and immediately in the event of its assignment, or in the
    event of a termination of the Adviser's agreement with the Trust. As used
    in this Section 8, the terms "assignment" and "vote of a majority of the
    outstanding voting securities" shall have the respective meanings set forth
    in the 1940 Act and the rules and regulations thereunder, subject to such
    exceptions as may be granted by the Commission under the 1940 Act.

                         SEI INSTITUTIONAL INVESTMENTS TRUST

    AGREEMENT made this 14th day of June, 1996, between SEI Financial
Management Corporation, (the "Adviser") and Merus-UCA Capital Management, a
division of the Union Bank of California, N.A. (the "Sub-Adviser").

    WHEREAS, SEI Institutional Investments Trust, a Massachusetts business
trust (the "Trust") is registered as an open-end management investment company
under the Investment Company Act of 1940, as amended (the " 1940 Act"); and

   
    WHEREAS, the Adviser has entered into an Investment Advisory Agreement
dated June 14, 1996 (the "Advisory Agreement") with the Trust, pursuant to
which the Adviser will act as investment adviser to the Large Cap Portfolio (the
"Portfolio"), each a series of the Trust; and
    

    WHEREAS, the Adviser, with the approval of the Trust, desires to retain the
Sub-Adviser to provide investment advisory services to the Adviser in connection
with the management of the Portfolio, and the Sub-Adviser is willing to render
such investment advisory services.

    NOW, THEREFORE, the parties hereto agree as follows:
    
1.  DUTIES OF THE SUB-ADVISER. Subject to supervision by the Adviser and the
    Trust's Board of Trustees, the Sub-Adviser shall manage all of the
    securities and other assets of the Portfolio entrusted to it hereunder (the
    "Assets"), including the purchase, retention and disposition of the Assets,
    in accordance with the Portfolio's investment objectives, policies and
    restrictions as stated in the Portfolio's prospectus and statement of
    additional information, as currently in effect and as amended or
    supplemented from time to time (referred to collectively as the
    "Prospectus"), and subject to the following:

    (a)  The Sub-Adviser shall, subject to the direction of the Adviser,
    determine what Assets will be purchased, retained or sold by the Portfolio,
    and what portion of the Assets will be invested or held uninvested in cash.

    (b)  In the performance of its duties and obligations under this Agreement,
    the Sub-Adviser shall act in conformity with the Trust's Declaration of
    Trust (as defined herein) and the Prospectus and with the written
    instructions and directions of the Adviser and of the Board of Trustees of
    the Trust and will conform to and comply with the requirements of the 1940
    Act, the Internal Revenue Code of 1986, and all other applicable federal
    and state laws and regulations, as each is amended from time to time. 

    (c)  The Sub-Adviser shall determine the Assets to be purchased or sold by
    the Portfolio as provided in subparagraph (a) and will place orders with or
    through such persons, brokers or dealers to carry out the policy with
    respect to brokerage set forth in the Portfolio's Registration Statement
    (as defined herein) and Prospectus or as the Board of Trustees or the
    Adviser may direct from time to time, in conformity with federal securities
    laws. In executing Portfolio transactions and selecting brokers or dealers,
    the Sub-Adviser will use its best efforts to seek on behalf of the
    Portfolio the best overall terms available. In assessing the best overall
    terms available for any transaction, the Sub-Adviser shall consider all
    factors that it deems relevant, including the breadth of the market in the
    security, the price of the security, the financial condition and execution


                                          1
<PAGE>

    capability of the broker or dealer, and the reasonableness of the
    commission, if any, both for the specific transaction and on a continuing
    basis. In evaluating the best overall terms available, and in selecting the
    broker-dealer to execute a particular transaction, the Sub-Adviser may also
    consider the brokerage and research services provided (as those terms are
    defined in Section 28(e) of the Securities Exchange Act of 1934).
    Consistent with any guidelines established by the Board of Trustees of the
    Trust, the Sub-Adviser is authorized to pay to a broker or dealer who
    provides such brokerage and research services a commission for executing a
    portfolio transaction for the Portfolio which is in excess of the amount of
    commission another broker or dealer would have charged for effecting that
    transaction if, but only if, the Sub-Adviser determines in good faith that
    such commission was reasonable in relation to the value of the brokerage
    and research services provided by such broker or dealer - - viewed in terms
    of that particular transaction or terms of the overall responsibilities of
    the Sub-Adviser to the Portfolio. In addition, the Sub-Adviser is
    authorized to allocate purchase and sale orders for securities to brokers
    or dealers (including brokers and dealers that are affiliated with the
    Adviser, Sub-Adviser or the Trust's principal underwriter) to take into
    account the sale of shares of the Trust if the Sub-Adviser believes that
    the quality of the transaction and the commission are comparable to what
    they would be with other qualified firms. In no instance, however, will the
    Portfolio's Assets be purchased from or sold to the Adviser, Sub-Adviser,
    the Trust's principal underwriter, or any affiliated person of either the
    Trust, Adviser, the Sub-Adviser or the principal underwriter, acting as
    principal in the transaction, except to the extent permitted by the
    Securities and Exchange Commission ("SEC") and the 1940 Act.

    (d)  The Sub-Adviser shall maintain all books and records with respect to
    transactions involving the Assets required by subparagraphs (b)(5), (6),
    (7), (9), (10) and (11) and paragraph (f) of Rule 31a-1 under the 1940
    Act. The Sub-Adviser shall provide to the Adviser or the Board of Trustees
    such periodic and special reports, balance sheets or financial information,
    and such other information with regard to its affairs as the Adviser or
    Board of Trustees may reasonably request.

    The Sub-Adviser shall keep the books and records relating to the Assets
    required to be maintained by the Sub-Adviser under this Agreement and shall
    timely furnish to the Adviser all information relating to the Sub-Adviser's
    services under this Agreement needed by the Adviser to keep the other books
    and records of the Portfolio required by Rule 31a-1 under the 1940 Act. The
    Sub-Adviser shall also furnish to the Adviser any other information
    relating to the Assets that is required to be filed by the Adviser or the
    Trust with the SEC or sent to shareholders under the 1940 Act (including
    the rules adopted thereunder) or any exemptive or other relief that the
    Adviser or the Trust obtains from the SEC. The Sub-Adviser agrees that all
    records that it maintains on behalf of the Portfolio are property of the
    Portfolio and the Sub-Adviser will surrender promptly to the Portfolio any
    of such records upon the Portfolio's request; provided, however, that the
    Sub-Adviser, may retain a copy of such records. In addition, for the
    duration of this Agreement, the Sub-Adviser shall preserve for the periods
    prescribed by Rule 31a-2 under the 1940 Act any such records as are
    required to be maintained by it pursuant to this Agreement, and shall
    transfer said records to any successor sub-adviser upon the termination of
    this Agreement (or, if there is no successor sub-adviser, to the Adviser).

    (e)  The Sub-Adviser shall provide the Portfolio's custodian on each
    business day with information relating to all transactions concerning the
    Portfolio's Assets and shall provide the Adviser with such information upon
    request of the Adviser.


                                          2
<PAGE>

    (f)  The investment management services provided by the Sub-Adviser under
    this Agreement are not to be deemed exclusive and the Sub-Adviser shall be
    free to render similar services to others, as long as such services do not
    impair the services rendered to the Adviser or the Trust.

    (g)  The Sub-Adviser shall promptly notify the Adviser of any financial
    condition that is likely to impair the Sub-Adviser's ability to fulfill its
    commitment under this Agreement.

    (h)  The Sub-Adviser shall review all proxy solicitation materials and be
    responsible for voting and handling all proxies in relation to the
    securities held in the Portfolio. The Adviser shall instruct the custodian
    and other parties providing services to the Portfolio to promptly forward
    misdirected proxies to the Sub-Adviser.

    Services to be furnished by the Sub-Adviser under this Agreement may be
    furnished through the medium of any of the Sub-Adviser's partners, officers
    or employees.

2.  DUTIES OF THE ADVISER. The Adviser shall continue to have responsibility
    for all services to be provided to the Portfolio pursuant to the Advisory
    Agreement and shall oversee and review the Sub-Adviser's performance of its
    duties under this Agreement; provided, however, that in connection with its
    management of the Assets, nothing herein shall be construed to relieve the
    Sub-Adviser of responsibility for compliance with the Trust's Declaration
    of Trust (as defined herein), the Prospectus, the instructions and
    directions of the Board of Trustees of the Trust, the requirements of the
    1940 Act, the Internal Revenue Code of 1986, and all other applicable
    federal and state laws and regulations, as each is amended from time to
    time.

3.  DELIVERY OF DOCUMENTS. The Adviser has furnished the Sub-Adviser with
    copies properly certified or authenticated of each of the following
    documents: 

    (a)  The Trust's Agreement and Declaration of Trust, as filed with the
    Secretary of State of the Commonwealth of Massachusetts (such Agreement and
    Declaration of Trust, as in effect on the date of this Agreement and as
    amended from time to time, herein called the "Declaration of Trust");

    (b)  By-Laws of the Trust (such By-Laws, as in effect on the date of this
    Agreement and as amended from time to time, are herein called the
    "By-Laws");

    (c) Prospectus(es) of the Portfolio.

4.  COMPENSATION TO THE SUB-ADVISER. For the services to be provided by the
    Sub-Adviser pursuant to this Agreement, the Adviser will pay the
    Sub-Adviser, and the Sub-Adviser agrees to accept as full compensation
    therefor, a sub-advisory fee at the rate specified in the Schedule(s)
    which is attached hereto and made part of this Agreement. The fee will be
    calculated based on the average monthly market value of the Assets under
    the Sub-Adviser's management and will be paid to the Sub-Adviser monthly.
    Except as may otherwise be prohibited by law or regulation (including any
    then current SEC staff interpretation), the Sub-Adviser may, in its
    discretion and from time to time, waive a portion of its fee.

5.  LIMITATION OF LIABILITY OF THE SUB-ADVISER. The Sub-Adviser shall not be
    liable for any error of judgment or for any loss suffered by the Adviser in
    connection with performance of its obligations under this Agreement, except
    a loss resulting from a breach of fiduciary duty with respect to the
    receipt of compensation for services (in which case any award of damages
    shall be limited to the


                                          3
<PAGE>

    period and the amount set forth in Section 36(b)(3) of the 1940 Act), or a
    loss resulting from willful misfeasance, bad faith or negligence on the
    Sub-Adviser's part in the performance of its duties or from reckless
    disregard of its obligations and duties under this Agreement, except as may
    otherwise be provided under provisions of applicable state law which cannot
    be waived or modified hereby.

6.  INDEMNIFICATION. The Sub-Adviser shall indemnify and hold harmless the
    Adviser from and against any and all claims, losses, liabilities or damages
    (including reasonable attorney's fees and other related expenses) howsoever
    arising from or in connection with the performance of the Sub-Adviser's
    obligations under this Agreement; provided, however, that the Sub-Adviser's
    obligation under this Section 6 shall be reduced to the extent that the
    claim against, or the loss, liability or damage experienced by the Adviser,
    is caused by or is otherwise directly related to the Adviser's own willful
    misfeasance, bad faith or negligence, or to the reckless disregard of its
    duties under this Agreement.

    The Adviser shall indemnify and hold harmless the Sub-Adviser from and
    against any and all claims, losses, liabilities or damages (including
    reasonable attorney's fees and other related expenses) howsoever arising
    from or in connection with the performance of the Adviser's obligations

    Trustees of the Trust or by the vote of a majority of the outstanding
    voting securities of the Portfolio, (b) by the Adviser at any time,
    without the payment of any penalty, on not more than 60 days' nor less than
    30 days' written notice to the Sub-Adviser, or (c) by the Sub-Adviser at
    any time, without the payment of any penalty, on 90 days' written notice to
    the Adviser. This Agreement shall terminate automatically and immediately
    in the event of its assignment, or in the event of a termination of the
    Adviser's agreement with the Trust. As used in this Section 7, the terms
    "assignment" and "vote of a majority of the outstanding voting securities"
    shall have the respective meanings set forth in the 1940 Act and the rules
    and regulations thereunder, subject to such exceptions as may be granted by

                          INVESTMENT SUB-ADVISORY AGREEMENT
                         SEI INSTITUTIONAL INVESTMENTS TRUST

    AGREEMENT made this 14th day of June, 1996, by and among SEI Financial
Management Corporation, (the "Adviser") and Montgomery Asset Management, L.P.
(the "Sub-Adviser").

    WHEREAS, SEI Institutional Investments Trust, a Massachusetts business
trust (the "Trust") is registered as an open-end management investment company
under the Investment Company Act of 1940, as amended (the "1940 Act"); and

    WHEREAS, the Adviser has entered into an Investment Advisory Agreement
dated June 14, 1996 (the "Advisory Agreement") with the Trust, pursuant to
which the Adviser will act as investment adviser to the Emerging Markets Equity
Portfolio (the "Portfolio"), which is a series of the Trust; and

    WHEREAS, the Adviser, with the approval of the Trust, desires to retain the
Sub-Adviser to provide investment advisory services to the Adviser in connection
with the management of the Portfolio, and the Sub-Adviser is willing to render
such investment advisory services.

    NOW, THEREFORE, the parties hereto agree as follows:

    1.   DUTIES OF THE SUB-ADVISER. Subject to supervision and direction by the
         Adviser and the Trust's Board of Trustees, the Sub-Adviser shall
         manage on a discretionary basis the investment operation of all of the
         securities and other assets of the Portfolio entrusted to it hereunder
         (the "Assets") and the composition of the Portfolio, including the
         purchase, retention and disposition of the Assets, in accordance with
         the Portfolio's investment objectives, policies and restrictions as
         stated in the Portfolio's prospectus and statement of additional
         information, as currently in effect and as amended or supplemented
         from time to time by written notice to the Sub-Adviser (referred to
         collectively as the "Prospectus"), and subject to the following:

    (a)  The Sub-Adviser shall provide supervision of the Assets and determine
         from time to time what Assets will be purchased, retained or sold by
         the Portfolio, and what portion of the Assets will be invested or held
         uninvested in cash. In furtherance of the forgoing, the Adviser hereby
         designates and appoints the Sub-Adviser as agent and attorney-in-fact
         of the Trust, with authority and without further approval of the
         Adviser (except as expressly provided for herein or as may be required
         by law) to make and execute, in the name and on behalf of the
         Portfolio, all agreements, instruments and other documents and to take
         all such other action which the Sub-Adviser considers necessary or
         advisable to carry out its duties hereunder. By way of example and not
         by way of limitation, in connection with any purchase for the
         Portfolio of securities that are not registered under the Securities
         Act of 1933, as amended (the "Securities Act"), the Sub-Adviser shall
         have authority, among other things to: (i) commit to purchase such 
         securities for the Portfolio on the terms and conditions under which
         such securities are offered; (ii) execute such agreements, instruments
         and documents (including, without limitation, purchase agreements and
         subscription documents), and make such commitments, as may be required
         or otherwise in connection with the purchase and sale or such
         securities; (iii) represent that the Portfolio is an "accredited
         investor" under the Securities Act; and (iv) commit that such
         securities will not be offered or sold by the Portfolio except in
         compliance with the registration requirements of the Securities Act or
         an exemption therefrom. This power-of-attorney is a continuing
         power-of-attorney and shall remain in full force and effect until 
         revoked by the Adviser in writing, but any such revocation shall not 
         affect any transaction initiated prior to receipt by the Sub-Adviser 
         or such notice.

<PAGE>

    (b)  In the performance of its duties and obligations under this 
         Agreement, the Sub-Adviser shall act in conformity with the Trust's
         Declaration of Trust (as defined herein) and the Prospectus and with 
         the instructions and directions of the Adviser and of the Board of
         Trustees of the Trust and will conform to and comply with the
         requirements of the 1940 Act, the Internal Revenue Code of 1986, and
         all other applicable federal and state laws and regulations, as each
         is amended from time to time.

    (c)  The Sub-Adviser shall determine the Assets to be purchased or sold by
         the Portfolio and will place orders with or through such persons,
         brokers or dealers to carry out the policy with respect to brokerage
         set forth in the Portfolio's Prospectus or as the Board of Trustees or
         the Adviser may direct from time to time, in conformity with federal
         securities laws. In executing Portfolio transactions and selecting
         brokers or dealers, the Sub-Adviser will use its best efforts to seek
         on behalf of the Portfolio the best overall terms available. In
         assessing the best overall terms available for any transaction, the
         Sub-Adviser shall consider all factors that it deems relevant,
         including the breadth of the market in the security, the price of the
         security, the financial condition and execution capability of the
         broker or dealer, and the reasonableness of the commission, if any,
         both for the specific transaction and on a continuing basis. In
         evaluating the best overall terms available, and in selecting the
         broker-dealer to execute a particular transaction the Sub-Adviser may
         also consider the brokerage and research services (as those terms are
         defined in Section 28(e) of the Securities Exchange Act of 1934)
         provided to the Portfolio and/or other accounts over which the
         Sub-Adviser or an affiliate of the Sub-Adviser may exercise investment
         discretion. The Sub-Adviser is authorized, subject to the prior
         approval of the Trust's Board of Trustees, to pay to a broker or
         dealer who provides such brokerage and research services a commission
         for executing a portfolio transaction for the Portfolio which is in
         excess of the amount of commission another broker or dealer would have
         charged for effecting that transaction if, but only if, the
         Sub-Adviser determines in good faith that such commission was
         reasonable in relation to the value of the brokerage and research
         services provided by such broker or dealer - - viewed in terms of that
         particular transaction or terms of the overall responsibilities of the
         Sub-Adviser to the Portfolio. In addition, the Sub-Adviser is 
         authorized to allocate purchase and sale orders for portfolio 
         securities to brokers or dealers (including brokers and dealers that
         are affiliated with the Adviser, the Sub-Adviser or the Trust's
         principal underwriter) to take into account the sale of shares of the
         Trust if the Sub-Adviser believes that the quality of the transaction
         and the commission are comparable to what they would be with other
         qualified firms. In no instance, however, will the Portfolio's Assets
         be purchased from or sold to the Adviser, the Sub-Adviser, the Trust's
         principal underwriter, or any affiliated person of either the Trust,
         the Adviser, the Sub-Adviser or the principal underwriter, acting as
         principal in the transaction, except to the extent permitted by the
         Securities and Exchange Commission and the 1940 Act.

    (d)  The Sub-Adviser shall maintain all books and records with respect to
         transactions involving the Assets required by subparagraphs (b)(5),
         (6), (7), (9), (10) and (11) and paragraph (f) of Rule 31a-1 
         under the 1940 Act and shall render to the Adviser or Board of Trustees
         such periodic and special reports as the Adviser or Board of Trustees 
         may reasonably request.

         The Sub-Adviser shall keep the books and records relating to the
         Assets required to be maintained by the Sub-Adviser under this
         Agreement and shall timely furnish to the Adviser all information
         requested by the Adviser relating to the Sub-Adviser's services under
         this Agreement needed by the Adviser to keep the other books and
         records of the Portfolio required by Rule 31a-1 under the 1940 Act.
         Upon request, the Sub-Adviser shall also furnish to the Adviser any
         other information relating to the Assets that is required to be filed
         by the Adviser or the Trust with the Securities and Exchange
         Commission ("SEC") or sent to shareholders under the 1940 Act
         (including the rules adopted thereunder) or any exemptive or other
         relief that the Adviser or the Trust obtains from the SEC. The
         Sub-Adviser agrees that all records that it maintains on behalf of the
         Portfolio are property of the Portfolio and the Sub-Adviser will

                                          2
<PAGE>

         surrender promptly to the Portfolio any of such records upon the
         Portfolio's request,; provided, however, that the Sub-Adviser may
         retain a copy of such records. In addition, for the duration of this
         Agreement, the Sub-Adviser shall preserve for the periods prescribed
         by Rule 31a-2 under the 1940 Act any such records as are required to
         be maintained by it pursuant to this Agreement, and shall transfer
         said records to any successor Sub-Adviser upon the termination of his
         Agreement (or, if there is no successor Sub-Adviser, to the Adviser).

    (e)  The Sub-Adviser shall provide the Portfolio's custodian on each
         business day with information relating to all transactions concerning
         the Portfolio's Assets and shall provide the Adviser with such
         information upon request of the Adviser.

    (f)  The investment management services provided by the Sub-Adviser under
         this Agreement are not to be deemed exclusive and the Sub-Adviser
         shall be free to render similar services to others, as long as such
         services do not impair the services rendered to the Adviser or the
         Trust.

              The Sub-Adviser shall not be obligated to purchase or sell for
         the Portfolio securities which the Sub-Adviser may purchase or sell or
         recommend for purchase or sale for itself or for the portfolios of
         other clients. Moreover, the Adviser acknowledges that circumstances
         may arise under which the Sub-Adviser determines that while it would 
         be both desirable and suitable that a particular security be purchased
         or sold for the account of more than one of the Sub-Adviser's 
         portfolios, there is a limited supply or demand for that security. 
         Under such circumstances, the Adviser acknowledges that, while the 
         Sub-Adviser will seek to allocate the opportunity to purchase or sell 
         that security among those portfolios on an equitable basis (including 
         as between portfolios of the Sub-Adviser's nondiscretionary clients, to
         whom the Sub-Adviser makes recommendations, and portfolios of its
         discretionary clients, such as the Portfolio), the Sub-Adviser shall
         not be required to assure equality of treatment among all of its
         clients (including that that opportunity to purchase or sell that
         security will be proportionately allocated among those portfolios
         according to any particular or predetermined standards or criteria).

              Where, because of the prevailing market conditions, it is not
         possible to receive the same price or time of execution for all of the
         securities or other investments purchased or sold for the Portfolio,
         transactions for the Portfolio may be reported with the average prices
         of those transactions. In certain instances, the Sub-Adviser, in its
         discretion, may place a large order to purchase or sell a particular
         security or other investment for the Portfolio and the accounts of one
         or more other clients. Because of the prevailing market conditions,
         it is frequently not possible to receive the same price or time of
         execution for all of the securities or other investments purchased or
         sold. When this occurs, the Sub-Adviser will average the various prices
         and charge or credit the Portfolio with the average price. In such
         instances, the confirmation for such transaction sent to the Adviser
         will disclose the average price. Upon request, the Sub-Adviser will
         make the underlying records reflecting the actual transaction
         available for the Adviser's inspection.

              The Portfolio may include securities of companies for which
         Montgomery Securities, an affiliate of the Sub-Adviser, acts as
         investment banker or financial adviser or with which it has other
         confidential relationships or in which it maintains a position or
         makes a market or otherwise has an interest. The Adviser appreciates
         that, for good commercial and legal reasons, nonpublic information (a)
         which becomes available to Montgomery Securities through its
         relationships or for any other reason cannot be passed on to the
         Sub-Adviser or the Adviser, or used for the benefit of the Portfolio;
         and (b) which becomes available to the Sub-Adviser for any reason
         cannot be passed onto the Adviser or used for the benefit of the
         Portfolio. The Adviser understands that Montgomery Securities, an
         affiliate of the Sub-Adviser may provide investment banking,
         investment advisory and brokerage services to persons other than the
         Adviser. These activities may result in a conflict between the
         interests of Montgomery

                                          3
<PAGE>

         Securities and the Adviser which, in certain circumstances, may
         restrict the Sub-Adviser from trading or recommending the trading in
         certain securities.

    (g)  The Sub-Adviser shall promptly notify the Adviser of any financial
         condition that is likely to impair the Sub-Adviser's ability to
         fulfill its commitment under this Agreement.

         (h)  The Adviser hereby authorizes the Sub-Adviser to receive and
         confer upon the Sub-Adviser complete discretion to vote proxies
         solicited by or with respect to the issuers of securities in which the
         Assets may be invested from time to time ("Proxies"). The Sub-Adviser
         shall vote all Proxies in a manner which, at the time of any Proxy
         vote is cast, is consistent with the Sub-Adviser's good faith
         judgment. The Adviser shall promptly deliver or cause to be delivered
         to the Sub-Adviser all Proxies, including any information with respect
         thereto, received by the Adviser or the Trust, or by any agent of the
         Adviser or the Trust, including without limitation, any custodian of
         the Assets. The Adviser shall hold the Sub-Adviser harmless for
         failure to vote Proxies, which are not received by, or delivered to,
         the Sub-Adviser in sufficient time to permit the Sub-Adviser to vote
         such Proxies in accordance with the Sub-Adviser's good faith judgment.

         Services to be furnished by the Sub-Adviser under this Agreement may
         be furnished through the medium of any of the Sub-Adviser's partners,
         officers or employees.

    2.   DUTIES OF THE ADVISER. The Adviser shall continue to have
         responsibility for all services to be provided to the Portfolio
         pursuant to the Advisory Agreement and shall oversee and review the
         Sub-Adviser's performance of its duties under this Agreement;
         provided, however, that nothing herein shall be construed to relieve
         the Sub-Adviser of responsibility for compliance with the Portfolio's
         investment objectives, policies, and restrictions, as provided in
         Section 1 hereunder, in connection with its management of the Assets.

    3.   DELIVERY OF DOCUMENTS. The Adviser has furnished the Sub-Adviser with
         copies properly certified or authenticated of each of the following
         documents, and will provide the Sub-Adviser with any amendments
         thereto prior to or immediately upon effectiveness:

    (a)  The Trust's Agreement and Declaration of Trust, as filed with the
         Secretary of State of the Commonwealth of Massachusetts (such
         Agreement and Declaration of Trust, as in effect on the date of this
         Agreement and as amended from time to time, herein called the
         "Declaration of Trust");

    (b)  By-Laws of the Trust (such By-Laws, as in effect on the date of this
         Agreement and as amended from time to time, is herein called the
         "By-Laws");

    (c)  Prospectus(es) of the Portfolio.

    4.   COMPENSATION TO THE SUB-ADVISER. For the services to be provided by
         the Sub-Adviser pursuant to this Agreement, the Adviser will pay the
         Sub-Adviser, and the Sub-Adviser agrees to accept as full compensation
         therefor, a sub-advisory fee at the rate specified in the Schedule(s)
         which is attached hereto and made part of this Agreement. The fee will
         be calculated based on the average monthly market value

                                          4
<PAGE>

         of the Assets under the Sub-Adviser's management and will be paid to
         the Sub-Adviser monthly. The Sub-Adviser may, in its discretion and
         from time to time, waive a portion of its fee.

    5.   LIMITATION OF LIABILITY OF THE SUB-ADVISER. The Sub-Adviser shall not
         be liable for any error of judgment or for any loss suffered by the 
         Adviser in connection with performance of its obligations under this
         Agreement, except a loss resulting from a breach of fiduciary duty
         with respect to the receipt of compensation for services (in which
         case any award of damages shall be limited to the period and the
         amount set forth in Section 36(b)(3) of the 1940 Act), or a loss
         resulting from willful misfeasance, bad faith or negligence on the
         Sub-Adviser's part in the performance of its duties or from reckless
         disregard of its obligations and duties under this Agreement, except
         as may otherwise be provided under provisions of applicable state law
         which cannot be waived or modified hereby.

    6.   REPORTS. During the term of this Agreement, the Adviser agrees to
         furnish the Sub-Adviser at its principal office all prospectuses,
         proxy statements, reports to stockholders, sales literature or other
         materials prepared for distribution to stockholders of the Portfolios,
         the Trust or the public that refer to the Sub-Adviser or its clients in
         any way prior to use thereof and not to use material if the Sub-Adviser
         reasonably objects in writing within five business days (or such other 
         period as may be mutually agreed) after receipt thereof. The 
         Sub-Adviser's right to object to such materials is limited to the 
         portions of such materials that expressly relate to the Sub-Adviser,
         its services and its clients. The Adviser agrees to use its reasonable
         best efforts to ensure that materials prepared by its employees
         or agents or its affiliates that refer to the Sub-Adviser or its 
         clients in any way are consistent with those materials previously
         approved by the Sub-Adviser as referenced in the first sentence of this
         paragraph. Sales literature may be furnished to the Sub-Adviser by 
         first class or overnight mail, facsimile transmission equipment or
         hand delivery.

    7.   INDEMNIFICATION. The Sub-Adviser shall indemnify and hold harmless the
         Adviser from and against any and all claims, losses, liabilities or
         damages (including reasonable attorney's fees and other related
         expenses) howsoever arising from or in connection with a breach by the
         Sub-Adviser of its duties and obligations under this Agreement;
         provided, however, that the Sub-Adviser shall not be required to
         indemnify or otherwise hold the Adviser harmless under this Section 7
         where the claim against, or the loss, liability or damage experienced
         by the Adviser is caused by or is otherwise directly related to the
         Adviser's own willful misfeasance, bad faith or negligence, or to the
         reckless disregard of its duties under this Agreement.

         The Adviser shall indemnify and hold harmless the Sub-Adviser from and
         against any and all claims, losses, liabilities or damages (including
         reasonable attorney's fees and other related expenses) howsoever
         arising from or in connection with a breach by the Adviser of its
         duties and obligations under this Agreement; provided, however, that
         the Adviser shall not be required to indemnify or otherwise hold the 
         Sub-Adviser harmless under this Section 7 where the claim against, or 
         the loss, liability or damage experienced by the Sub-Adviser is caused 
         by or is otherwise directly related to the Sub-Adviser's own willful 
         misfeasance, bad faith or negligence, or to the reckless disregard of
         its duties under this Agreement.

    8.   CUSTODY. The custodian of the assets comprising the Emerging Markets
         Equity Portfolio will be State Street Bank and Trust Company (the
         "Custodian"). The Assets will be maintained by the Custodian in a
         subaccount, separately identified from the other assets of the
         Emerging Markets Equity Portfolio and the Trust. All transactions with
         respect to assets in the Portfolio will be carried out through the 
         Custodian or such other custodians of the Portfolio as approved or
         appointed by the Portfolio.

                                          5

    9.   DURATION AND TERMINATION. This Agreement shall become effective upon 
         its approval by the Trust's Board of Trustees and by the vote of a 
         majority of the outstanding voting securities of the Portfolio; 
         provided, however, that at any time the Adviser shall have obtained 
         exemptive relief from the SEC permitting it to engage a Sub-Adviser 
         without first obtaining approval of the Agreement from a majority of 
         the outstanding voting securities of the Portfolio(s) involved, the 
         Agreement shall become effective upon its approval by the Trust's 
         Board of Trustees. Any Sub-Adviser so selected and approved shall be 
         without the protection accorded by shareholder approval of an 
         investment adviser's receipt of compensation under Section 36(b) of 
         the 1940 Act.

         This Agreement shall continue in effect for a period of more than two
         years from the date hereof only so long as continuance is 
         specifically approved at least annually in conformance with the 1940 
         Act; provided, however, that this Agreement may be terminated with 
         respect to the Portfolio (a) by the Portfolio at any time, without 
         the payment of any penalty, by the vote of a majority of Trustees of 
         the Trust or by the vote of a majority of the outstanding voting 
         securities of the Portfolio, (b) by the Adviser at any time, without 
         the payment of any penalty, on not more than 60 days' nor less than 
         30 days' written notice to the Sub-Adviser, or (c) by the 
         Sub-Adviser at any time, without the payment of any penalty, on 90 
         days' written notice to the Adviser. This Agreement shall terminate 
         automatically and immediately in the event of its assignment, or in 
         the event of a termination of the Adviser's agreement with the 
         Trust. As used in this Section 8, the terms "assignment" and "vote 
         of a majority of the outstanding voting securities" shall have the
         respective meanings set forth in the 1940 Act and the rules and 
         regulations thereunder, subject to such exceptions as may be granted 
         by the Commission under the 1940 Act.

                        INVESTMENT SUB-ADVISORY AGREEMENT
                       SEI INSTITUTIONAL INVESTMENTS TRUST

     AGREEMENT made this 14th day of June, 1996, between SEI Financial
Management Corporation, (the "Adviser") and Nicholas-Applegate Capital
Management (the Sub-Adviser).

     WHEREAS, SEI Institutional Investments Trust, a Massachusetts business
trust (the "Trust") is registered as an open-end management investment company
under the Investment Company Act of 1940, as amended (the "1940 Act"); and

     WHEREAS, the Adviser has entered into an Investment Advisory Agreement
dated June 14, 1996 (the "Advisory Agreement") with the Trust, pursuant to which
the Adviser will act as investment adviser to the Small Cap Portfolio (the
"Portfolio"), which is a series of the Trust; and

     WHEREAS, the Adviser, with the approval of the Trust, desires to retain the
Sub-Adviser to provide investment advisory services to the Adviser in connection
with the management of the Portfolio, and the Sub-Adviser is willing to render
such investment advisory services.

     NOW, THEREFORE, the parties hereto agree as follows:

1.   DUTIES OF THE SUB-ADVISER. Subject to supervision by the Adviser and the
     Trust's Board of Trustees, the Sub-Adviser shall manage all of the
     securities and other assets of the Portfolio entrusted to it hereunder (the
     "Assets"), including the purchase, retention and disposition of the Assets,
     in accordance with the Portfolio's investment objectives, policies and
     restrictions as stated in the Portfolio's prospectus and statement of
     additional information, as currently in effect and as amended or
     supplemented from time to time (referred to collectively as the
     "Prospectus"), and subject to the following:

(a)  The Sub-Adviser shall, in consultation with and subject to the direction of
     the Adviser, determine from time to time what Assets will be purchased,
     retained or sold by the Portfolio, and what portion of the Assets will be
     invested or held uninvested in cash.

(b)  In the performance of its duties and obligations under this Agreement, the
     Sub-Adviser shall act in conformity with the Trust's Declaration of Trust
     (as defined herein) and the Prospectus and with the instructions and
     directions of the Adviser and of the Board of Trustees of the Trust and
     will conform to and comply with the requirements of the 1940 Act, the
     Internal Revenue Code of 1986, and all other applicable federal and state
     laws and regulations, as each is amended from time to time.

(c)  The Sub-Adviser shall determine the Assets to be purchased or sold by the
     Portfolio as provided in subparagraph (a) and will place orders with or
     through such persons, brokers or dealers to carry out the policy with
     respect to brokerage set forth in the Portfolio's Registration Statement
     (as defined herein) and Prospectus or as the Board of Trustees or the
     Adviser may direct from time to time, in conformity with federal securities
     laws. In executing Portfolio transactions and selecting brokers or dealers,
     the Sub-Adviser will use its best efforts to seek on behalf of the
     Portfolio the best overall terms available. In assessing the best overall
     terms available for any transaction, the Sub-Adviser shall consider all
     factors that it deems relevant, including the breadth of the market in the
     security, the price of the security, the financial condition and execution
     capability of the broker or dealer, and the reasonableness of the
     commission, if any, both for the specific transaction and on a continuing
     basis. In evaluating the best overall terms available, and in selecting the
     broker-dealer to execute a particular transaction, the Sub-Adviser may also
<PAGE>

     consider the brokerage and research services provided (as those terms are
     defined in Section 28(e) of the Securities Exchange Act of 1934).
     Consistent with any guidelines established by the Board of Trustees of the
     Trust, the Sub-Adviser is authorized to pay to a broker or dealer who
     provides such brokerage and research services a commission for executing a
     portfolio transaction for the Portfolio which is in excess of the amount of
     commission another broker or dealer would have charged for effecting that
     transaction if, but only if, the Sub-Adviser determines in good faith that
     such commission was reasonable in relation to the value of the brokerage
     and research services provided by such broker or dealer -- viewed in terms
     of that particular transaction or terms of the overall responsibilities of
     the Sub-Adviser to the Portfolio. In addition, the Sub-Adviser if
     authorized to allocate purchase and sale orders for securities to brokers
     or dealers (including brokers and dealers that are affiliated with the
     Adviser, Sub-Adviser or the Trust's principal underwriter) to take into
     account the sale of shares of the Trust if the Sub-Adviser believes that
     the quality of the transaction and the commission are comparable to what
     they would be with other qualified firms. In no instance, however, will the
     Portfolio's Assets be purchased from or sold to the Adviser, Sub-Adviser,
     the Trust's principal underwriter, or any affiliated person of either the
     Trust, Adviser, the Sub-Adviser or the principal underwriter, acting as
     principal in the transaction, except to the extent permitted by the
     Securities and Exchange Commission and the 1940 Act.

(d)  The Sub-Adviser shall maintain all books and records with respect to
     transactions involving the Assets required by subparagraphs (b)(5), (6),
     (7), (9), (10) and (11) and paragraph (f) of Rule 31a-1 under the 1940 Act.
     The Sub-Adviser shall provide to the Adviser or the Board of Trustees such
     periodic and special reports, balance sheets or financial information, and
     such other information with regard to its affairs as the Adviser or Board
     of Trustees may reasonably request.

     The Sub-Adviser shall keep the books and records relating to the Assets
     required to be maintained by the Sub-Adviser under this Agreement and shall
     timely furnish to the Adviser all information relating to the Sub-Adviser's
     services under this Agreement needed by the Adviser to keep the other books
     and records of the Portfolio required by Rule 31a-1 under the 1940 Act. The
     Sub-Adviser shall also furnish to the Adviser any other information
     relating to the Assets that is required to be filed by the Adviser or the
     Trust with the Securities and Exchange Commission ("SEC") or sent to
     shareholders under the 1940 Act (including the rules adopted thereunder) or
     any exemptive or other relief that the Adviser or the Trust obtains from
     the SEC. The Sub-Adviser agrees that all records that it maintains on
     behalf of the Portfolio are property of the Portfolio and the Sub-Adviser
     will surrender promptly to the Portfolio any of such records upon the
     Portfolio's request; provided, however, that the Sub-Adviser may retain a
     copy of such records. In addition, for the duration of this Agreement, the
     Sub-Adviser shall preserve for the periods prescribed by Rule 31a-2 under
     the 1940 Act any such records as are required to be maintained by it
     pursuant to this Agreement, and shall transfer said records to any
     successor Sub-Adviser upon the termination of his Agreement (or, if there
     is no successor Sub-Adviser, to the Adviser).

(e)  The Sub-Adviser shall provide the Portfolio's custodian on each business
     day with information relating to all transactions concerning the
     Portfolio's Assets and shall provide the Adviser with such information upon
     request of the Adviser.

(f)  The investment management services provided by the Sub-Adviser under this
     Agreement are not to be deemed exclusive and the Sub-Adviser shall be free
     to render similar services to others, as long as such services do not
     impair the services rendered to the Adviser or the Trust.
<PAGE>

(g)  The Sub-Adviser shall promptly notify the Adviser of any financial 
     condition that is likely to impair the Sub-Adviser's ability to fulfill its
     commitment under this Agreement. The Sub-Adviser will notify the Adviser of
     any change in its partners within a reasonable time.

(h)  The Sub-Adviser shall review all proxy solicitation materials and be
     responsible for voting and handling all proxies in relation to the
     securities held in the Portfolio. The Adviser shall instruct the custodian
     and other parties providing services to the Portfolio to promptly forward
     misdirected proxies to the Sub-Adviser.

     Services to be furnished by the Sub-Adviser under this Agreement may be
     furnished through the medium of any of the Sub-Adviser's partners, officers
     or employees.

2.   DUTIES OF THE ADVISER. The Adviser shall continue to have responsibility
     for all services to be provided to the Portfolio pursuant to the Advisory
     Agreement and shall oversee and review the Sub-Adviser's performance of its
     duties under this Agreement; provided, however, that in connection with its
     management of the Assets, nothing herein shall be construed to relieve the
     Sub-Adviser of responsibility for compliance with the Trust's Declaration
     of Trust (as defined herein), the Prospectus, the instructions and
     directions of the Board of Trustees of the Trust, the requirements of the
     1940 Act, the Internal Revenue Code of 1986, and all other applicable
     federal and state laws and regulations, as each is amended from time to
     time.

3.   DELIVERY OF DOCUMENTS. The Adviser has furnished the Sub-Adviser with
     copies properly certified or authenticated of each of the following
     documents:

(a)  The Trust's Agreement and Declaration of Trust, as filed with the Secretary
     of State of the Commonwealth of Massachusetts (such Agreement and
     Declaration of Trust, as in effect on the date of this Agreement and as
     amended from time to time, herein called the "Declaration of Trust");

(b)  By-Laws of the Trust (such By-Laws, as in effect on the date of this
     Agreement and as amended from time to time, are herein called the
     "By-Laws");

(c)  Prospectus(es) of the Portfolio.

4.   COMPENSATION TO THE SUB-ADVISER. For the services to be provided by the
     Sub-Adviser pursuant to this Agreement, the Adviser will pay the
     Sub-Adviser, and the Sub-Adviser agrees to accept as full compensation
     therefor, a sub-advisory fee at the rate specified in the Schedule(s) which
     is attached hereto and made part of this Agreement. The fee will be
     calculated based on the average monthly market value of the Assets under
     the Sub-Adviser's management and will be paid to the Sub-Adviser monthly.
     Except as may otherwise be prohibited by law or regulation (including any
     then current SEC staff interpretation), the Sub-Adviser may, in its
     discretion and from time to time, waive a portion of its fee.

5.   LIMITATION OF LIABILITY OF THE SUB-ADVISER. The Sub-Adviser shall not be
     liable for any error of judgment or for any loss suffered by the Adviser in
     connection with the performance of its obligations under this Agreement,
     except a loss resulting from a breach of fiduciary duty with respect to the
     receipt of compensation for services (in which case any award of damages
     shall be limited to the period and the amount set forth in Section 36(b)(3)
     of the 1940 Act), or a loss resulting from willful misfeasance, bad faith
     or negligence on the Sub-Adviser's part in the performance of its duties or
     from reckless disregard of its obligations and duties under this Agreement,
     except as may otherwise be provided under provisions of applicable state
     law which cannot be waived or modified hereby.
<PAGE>

6.   INDEMNIFICATION. The Sub-Adviser shall indemnify and hold harmless the
     Adviser from and against any and all claims, losses, liabilities or damages
     (including reasonable attorney's fees and other related expenses) howsoever
     arising from or in connection with the performance of the Sub-Adviser's
     obligations under this Agreement; provided, however, that the Sub-Adviser's
     obligation under this Section 6 shall be reduced to the extent that the
     claim against, or the loss, liability or damage experienced by the Adviser,
     is caused by or is otherwise directly related to the Adviser's own willful
     misfeasance, bad faith or negligence, or to the reckless disregard of its
     duties under this Agreement.

     The Adviser shall indemnify and hold harmless the Sub-Adviser from and
     against any and all claims, losses, liabilities or damages (including
     reasonable attorney's fees and other related expenses) howsoever arising
     from or in connection with the performance of the Adviser's obligations
     under this Agreement; provided, however, that the Adviser's obligation
     under this Section 6 shall be reduced to the extent that the claim against,

     by or is otherwise directly related to the Sub-Adviser's own willful
     misfeasance, bad faith or negligence, or the reckless disregard of its
     duties under this Agreement.

7.   DURATION AND TERMINATION.  This Agreement shall become effective upon 
     its approval by the Trust's Board of Trustees and by the vote of a 
     majority of the outstanding voting securities of the Portfolio.
     This Agreement shall continue in effect for a period of more than two
     years from the date hereof only so long as continuance is specifically 
     approved at least annually in conformance with the 1940 Act; provided, 
     however, that this Agreement may be terminated with respect to the 
     Portfolio (a) by the Portfolio at any time, without the payment of any 
     penalty, by the vote of a majority of Trustees of the Trust or by the vote
     of a majority of the outstanding voting securities of the Portfolio, (b) by
     the Adviser at any time, without the payment of any penalty, on not more
     than 60 days' nor less than 30 days' written notice to the Sub-Adviser, 
     or (c) by the Sub-Adviser at any time, without the payment of any penalty,
     on 90 days' written notice to the Adviser.  This Agreement shall terminate 
     automatically and immediately in the event of its assignment, or in the 
     event of a termination of the Adviser's agreement with the Trust.  As used
     in this Section 7, the terms "assignment" and "vote of a majority of 
     the outstanding voting securities" shall have the respective meanings set 
     forth in the 1940 Act and the rules and regulations thereunder, subject to 
     such exceptions as may be granted by the Commission under the 1940 Act.

    "Assets"), including the purchase, retention and disposition of the Assets,
    in accordance with the Portfolio's investment objectives, policies and
    restrictions as stated in the Portfolio's prospectus and statement of
    additional information, as currently in effect and as amended or
    supplemented from time to time (referred to collectively as the
    "Prospectus"), and subject to the following:

(a) The Sub-Adviser shall, in consultation with and subject to the direction of
    the Adviser, determine from time to time what Assets will be purchased,
    retained or sold by the Portfolio, and what portion of the Assets will be
    invested or held uninvested in cash.

(b) In the performance of its duties and obligations under this Agreement, the
    Sub-Adviser shall act in conformity with the Trust's Declaration of Trust
    (as defined herein) and the Prospectus and with the instructions and
    directions of the Adviser and of the Board of Trustees of the Trust and
    will conform to and comply with the requirements of the 1940 Act, the
    Internal Revenue Code of 1986, and all other applicable federal and state
    laws and regulations, as each is amended from time to time.

(c) The Sub-Adviser shall determine the Assets to be purchased or sold by the
    Portfolio as provided in subparagraph (a) and will place orders with or
    through such persons, brokers or dealers to carry out the policy with
    respect to brokerage set forth in the Portfolio's Registration Statement
    (as defined herein) and Prospectus or as the Board of Trustees or the
    Adviser may direct from time to time, in conformity with federal securities
    laws.  In executing Portfolio transactions and selecting brokers or
    dealers, the Sub-Adviser will use its best efforts to seek on behalf of the
    Portfolio the best overall terms available.  In assessing the best overall
    terms available for any transaction, the Sub-Adviser shall consider all
    factors that it deems relevant, including the breadth of the market in the
    security, the price of the security, the financial condition and execution
    capability of the broker or dealer, and the reasonableness of the
    commission, if any, both for the specific transaction and on a continuing
    basis.  In evaluating the best overall terms available, and in selecting
    the broker-dealer to execute a particular transaction, the Sub-Adviser may
    also consider the brokerage and research services provided (as those terms
    are defined in Section 28(e) of the Securities Exchange Act of 1934). 
    Consistent with any guidelines established by the Board of Trustees of the
    Trust, the Sub-Adviser is authorized to pay to a broker or dealer who
    provides such brokerage and research services a commission for executing a
    portfolio transaction for the 



<PAGE>

    Portfolio which is in excess of the amount of commission another broker or
    dealer would have charged for effecting that transaction if, but only if,
    the Sub-Adviser determines in good faith that such commission was
    reasonable in relation to the value of the brokerage and research services
    provided by such broker or dealer -- viewed in terms of that particular
    transaction or terms of the overall responsibilities of the Sub-Adviser to
    the Portfolio.  In addition, the Sub-Adviser if authorized to allocate
    purchase and sale orders for securities to brokers or dealers (including
    brokers and dealers that are affiliated with the Adviser, Sub-Adviser or
    the Trust's principal underwriter) to take into account the sale of shares
    of the Trust if the Sub-Adviser believes that the quality of the
    transaction and the commission are comparable to what they would be with
    other qualified firms.  In no instance, however, will the Portfolio's
    Assets be purchased from or sold to the Adviser, Sub-Adviser, the Trust's
    principal underwriter, or any affiliated person of either the Trust,
    Adviser, the Sub-Adviser or the principal underwriter, acting as principal
    in the transaction, except to the extent permitted by the Securities and
    Exchange Commission ("SEC") and the 1940 Act.

(d) The Sub-Adviser shall maintain all books and records with respect to
    transactions involving the Assets required by subparagraphs (b)(5), (6),
    (7), (9), (10) and (11) and paragraph (f) of Rule 31a-1 under the 1940 Act. 
    The Sub-Adviser shall provide to the Adviser or the Board of Trustees such
    periodic and special reports, balance sheets or financial information, and
    such other information with regard to its affairs as the Adviser or Board
    of Trustees may reasonably request.

    The Sub-Adviser shall keep the books and records relating to the Assets
    required to be maintained by the Sub-Adviser under this Agreement and shall
    timely furnish to the Adviser all information relating to the Sub-Adviser's
    services under this Agreement needed by the Adviser to keep the other books
    and records of the Portfolio required by Rule 31a-1 under the 1940 Act. 
    The Sub-Adviser shall also furnish to the Adviser any other information
    relating to the Assets that is required to be filed by the Adviser or the
    Trust with the SEC or sent to shareholders under the 1940 Act (including
    the rules adopted thereunder) or any exemptive or other relief that the
    Adviser or the Trust obtains from the SEC.  The Sub-Adviser agrees that all
    records that it maintains on behalf of the Portfolio are property of the
    Portfolio and the Sub-Adviser will surrender promptly to the Portfolio any
    of such records upon the Portfolio's request; provided, however, that the
    Sub-Adviser may retain a copy of such records.  In addition, for the
    duration of this Agreement, the Sub-Adviser shall preserve for the periods
    prescribed by Rule 31a-2 under the 1940 Act any such records as are
    required to be maintained by it pursuant to this Agreement, and shall
    transfer said records to any successor sub-adviser upon the termination of
    this Agreement (or, if there is no successor sub-adviser, to the Adviser).

(e) The Sub-Adviser shall provide the Portfolio's custodian on each business
    day with information relating to all transactions concerning the
    Portfolio's Assets and shall provide the Adviser with such information upon
    request of the Adviser.

(f) The investment management services provided by the Sub-Adviser under this
    Agreement are not to be deemed exclusive and the Sub-Adviser shall be free
    to render similar services to others, as long as such services do not
    impair the services rendered to the Adviser or the Trust.

(g) The Sub-Adviser shall promptly notify the Adviser of any financial
    condition that is likely to impair the Sub-Adviser's ability to fulfill its
    commitment under this Agreement.

(h) The Sub-Adviser shall review all proxy solicitation materials and be
    responsible for voting and handling all proxies in relation to the
    securities held in the Portfolio.  The Adviser shall instruct the custodian
    and other parties providing services to the Portfolio to promptly forward
    misdirected proxies to the Sub-Adviser.

    Services to be furnished by the Sub-Adviser under this Agreement may be
    furnished through the medium of any of the Sub-Adviser's partners, officers
    or employees.

2.  DUTIES OF THE ADVISER.  The Adviser shall continue to have responsibility
    for all services to be provided to the Portfolio pursuant to the Advisory
    Agreement and shall oversee and review the Sub-Adviser's performance of its
    duties under this Agreement; provided, however, that in connection with its
    management of the Assets, nothing herein shall be construed to relieve the
    Sub-Adviser of responsibility for compliance with the Trust's Declaration
    of Trust (as defined herein), the Prospectus, the instructions and
    directions of the Board of Trustees of the Trust, the requirements of the
    1940 Act, the Internal Revenue Code of 1986, and all other applicable
    federal and state laws and regulations, as each is amended from time to
    time.

3.  DELIVERY OF DOCUMENTS.  The Adviser has furnished the Sub-Adviser with
    copies properly certified or authenticated of each of the following
    documents:

(a) The Trust's Agreement and Declaration of Trust, as filed with the Secretary
    of State of the Commonwealth of Massachusetts (such Agreement and
    Declaration of Trust, as in effect on the date of this Agreement and as
    amended from time to time, herein called the "Declaration of Trust");

(b) By-Laws of the Trust (such By-Laws, as in effect on the date of this
    Agreement and as amended from time to time, are herein called the 
    "By-Laws");

4.  COMPENSATION TO THE SUB-ADVISER.  For the services to be provided by the
    Sub-Adviser pursuant to this Agreement, the Adviser will pay the 
    Sub-Adviser, and the Sub-Adviser agrees to accept as full compensation
    therefor, a sub-advisory fee at the rate specified in the Schedule(s) which
    is attached hereto and made part of this Agreement.  The fee will be
    calculated based on the average monthly market value of the Assets under
    the Sub-Adviser's management and will be paid to the Sub-Adviser monthly. 
    Except as may otherwise be prohibited by law or regulation (including any
    then current SEC staff interpretation), the Sub-Adviser may, in its
    discretion and from time to time, waive a portion of its fee.

5.  INDEMNIFICATION.  The Sub-Adviser shall indemnify and hold harmless the
    Adviser from and against any and all claims, losses, liabilities or damages
    (including reasonable attorney's fees and other related expenses) howsoever
    arising from or in connection with the performance of the Sub-Adviser s
    obligations under this Agreement; provided, however, that the Sub-Adviser s
    obligation under this Section 5 shall be reduced to the extent that the
    claim against, or the loss, liability or damage experienced by the Adviser,
    is caused by or is otherwise directly related to the Adviser's own willful
    misfeasance, bad faith or negligence, or to the reckless disregard of its
    duties under this Agreement. 


6.  DURATION AND TERMINATION.  This Agreement shall become effective upon its
    approval by the Trust's Board of Trustees and by the vote of a majority of
    the outstanding voting securities of the Portfolio.  This Agreement shall
    continue in effect for a period of more than two years from the date hereof
    only so long as continuance is specifically approved at least annually in
    conformance with the 1940 Act; provided, however, that this Agreement may
    be terminated with respect to the Portfolio (a) by the Portfolio at any
    time, without the payment of any penalty, by the vote of a majority of
    Trustees of the Trust or by the vote of a majority of the outstanding
    voting securities of the Portfolio, (b) by the Adviser at any time, without
    the payment of any penalty, on not more than 60 days' nor less than 30
    days' written notice to the Sub-Adviser, or (c) by the Sub-Adviser at any
    time, without the payment of any penalty, on 90 days' written 


                                         -3-

    notice to the Adviser.  This Agreement shall terminate automatically and
    immediately in the event of its assignment, or in the event of a
    termination of the Adviser's agreement with the Trust.  As used in this
    Section 6, the terms "assignment" and "vote of a majority of the
    outstanding voting securities" shall have the respective meanings set forth
    in the 1940 Act and the rules and regulations thereunder, subject to such
    exceptions as may be granted by the SEC under the 1940 Act.

7.  GOVERNING LAW.  This Agreement shall be governed by the internal laws of
    the Commonwealth of Massachusetts, without regard to conflict of law
    principles; provided, however, that nothing herein shall be construed as
    being inconsistent with the 1940 Act.

8.  SEVERABILITY.  Should any part of this Agreement be held invalid by a court
    decision, statute, rule or otherwise, the remainder of this Agreement shall
    not be affected thereby.  This Agreement shall be binding upon and shall

                        INVESTMENT SUB-ADVISORY AGREEMENT
                       SEI INSTITUTIONAL INVESTMENTS TRUST

     AGREEMENT made this 14th day of June, 1996, by and between SEI Financial
Management Corporation (the "Adviser") and Strategic Fixed Income, L.P. (the
"Sub-Adviser").

     WHEREAS, SEI Institutional Investments Trust, a Massachusetts business
trust (the "Trust"), is registered as an open-end management investment company
under the Investment Company Act of 1940, as amended (the "1940 Act"); and

     WHEREAS, the Adviser has entered into an Investment Advisory Agreement
dated June 14, 1996 (the "Advisory Agreement") with the Trust, pursuant to which
the Adviser acts as investment adviser to the International Fixed Income
Portfolio (the "Portfolio"), which is a series of the Trust; and

     WHEREAS, the Adviser, with the approval of the Trust, desires to retain the
Sub-Adviser to provide investment advisory services to the Adviser in connection
with the management of the Portfolio, and the Sub-Adviser is willing to render
such investment advisory services, upon the terms and subject to the conditions
set forth below.

     NOW, THEREFORE, the parties hereto agree as follows:

1.   DUTIES OF THE SUB-ADVISER. Subject to supervision by the Adviser and the
     Trust's Board of Trustees, the Sub-Adviser shall manage all of the
     securities and other assets of the Portfolio entrusted to it by the Adviser
     ("the Assets"), including the purchase, retention and disposition of the
     Assets, in accordance with the Portfolio's investment objectives, policies
     and restrictions as stated in the Portfolio s prospectus and statement of
     additional information, as currently in effect and as amended or
     supplemented from time to time (referred to collectively as the
     "Prospectus"), provided the Sub-Adviser shall be given reasonable advance
     notice of any such amendments and supplements, and subject to the
     following:

(a)  The Sub-Adviser, subject to the direction of the Adviser, and, at the
     request of the Adviser, in consultation with the Adviser, shall determine
     from time to time what Assets will be purchased, retained or disposed of by
     the Portfolio, and what portion of the Assets will be invested or held
     uninvested in cash.

(b)  In the performance of its duties and obligations under this Agreement, the
     Sub-Adviser shall act in conformity with the Trust's Declaration of Trust
     (as defined herein) and the Prospectus and with the instructions and
     directions of the Adviser and of the Board of Trustees of the Trust and
     will conform to and comply with the applicable requirements of the 1940
     Act, the applicable requirements of Subchapter M of the Internal Revenue
     Code of 1986, and all other applicable federal and state laws and
     regulations, as each is amended from time to time; provided, however, that
     in no event shall the Sub-Adviser be obligated to act in conformity with
     and instruction or direction of the Adviser or of the Board of Trustees of
     the Trust if the Sub-Adviser believes in good faith (in consultation with
     counsel, where practicable) that implementation of such instruction or
     direction would involve the Sub-Adviser in a violation of law or willful
     malfeasance, bad faith or gross negligence on its part.

(c)  The Sub-Adviser shall determine the Assets to be purchased or disposed of
     by the Portfolio as provided in subparagraph (a) and will place orders with
     or through such brokers, dealers or banks to carry out the policy with
     respect to brokerage set forth in the Portfolio's


<PAGE>

     Prospectus or as the Board of Trustees or the Adviser may direct from time
     to time, in conformity with federal securities laws. In executing Portfolio
     transactions and selecting brokers, dealers or banks the Sub-Adviser will
     use its best efforts to seek on behalf of the Portfolio the best overall
     terms available. In assessing the best overall terms available for any
     transaction, the Sub-Adviser shall consider all factors that it deems
     relevant, including the breadth of the market in the security, the price of
     the security, the financial condition and execution capability of the
     broker, dealer, or bank and the reasonableness of the commission, if any,
     both for the specific transaction and on a continuing basis.

     The Sub-Adviser is authorized to allocate purchase and sale orders for
     securities to brokers or dealers (including brokers and dealers that are
     affiliated with the Adviser, Sub-Adviser or the Trust's principal
     underwriter) to take into account the sale of shares of the Trust if the
     Sub-Adviser believes that the quality of the transaction and the commission
     are comparable to what they would be with other qualified firms. In no
     instance, however, will the Portfolio s Assets be purchased from or sold to
     the Adviser, Sub-Adviser, the Trust's principal underwriter, or any
     affiliated person of either the Trust, Adviser, the Sub-Adviser or the
     principal underwriter, acting as principal in the transaction, except to
     the extent permitted by or under the 1940 Act or by the Securities and
     Exchange Commission ("SEC").

(d)  The Sub-Adviser shall maintain all books and records with respect to
     transactions involving the Assets required by subparagraphs (b)(5), (6),
     (7), (9), (10) and (11) and paragraph (f) of Rule 31-1 under the 1940 Act
     and shall render to the Adviser or Board of Trustees such periodic and
     special reports as the Adviser or Board of Trustees may reasonably request.

     The Sub-Adviser shall keep the books and records relating to the Assets
     required to be maintained by the Sub-Adviser under this Agreement and shall
     timely furnish to the Adviser, at its request, all information relating to
     the Sub-Adviser's services under this Agreement needed by the Adviser to
     keep the other books and records of the Portfolio required by Rule 31a-1
     under the 1940 Act. The Sub-Adviser shall also furnish to the Adviser, at
     its request, any other information relating to the Assets that is required
     to be filed by the Adviser or the Trust with the SEC or sent to
     shareholders under the 1940 Act (including the rules adopted thereunder) or
     any exemptive or other relief that the Adviser or the Trust obtains from
     the SEC, in each case with respect to the Trust, the Portfolio, or the
     Assets. The Sub-Adviser agrees that all records that it maintains on behalf
     of the Portfolio are property of the Portfolio and the Sub-Adviser will
     surrender promptly to the Portfolio any of such records upon the
     Portfolio's request; provided, however, that the Sub-Adviser may retain a
     copy of such records. In addition, for the duration of this Agreement, the
     Sub-Adviser shall preserve for the periods prescribed by Rule 31a-2 under
     the 1940 Act any such records as are required to be maintained by it
     pursuant to this Agreement, and shall transfer said records to any
     successor Sub-Adviser upon the termination of his Agreement (or, if there
     is no successor Sub-Adviser, to the Adviser); provided, however, that the
     Sub-Adviser may retain a copy of such records.


                                       -2-
<PAGE>


(e)  The Sub-Adviser shall provide the Portfolio's custodian on each business
     day with information relating to all transactions concerning the
     Portfolio's Assets and shall provide the Adviser with such information upon
     request of the Adviser.

(f)  The Sub-Adviser and its partners and its and their respective partners,
     stockholders, directors, officers, employees and agents act, may continue
     to act and in the future may act as investment managers or investment
     advisers to others and may invest for their own accounts, and nothing in
     this Agreement shall in any way be construed or deemed to restrict the
     right of any such person to perform investment management or investment
     advisory services for others or to invest for its own account, and the
     performance of such services for others and such investing shall not be
     deemed to violate or give rise to any duty or obligation to the Trust, the
     Portfolio or the Adviser, except as otherwise provided by law. The
     Sub-Adviser agrees to act in a manner consistent with its fiduciary
     obligation to deal fairly with all clients when taking investment actions.

(g)  The Sub-Adviser shall promptly notify the Adviser of any financial
     condition that is likely to materially impair the Sub-Adviser's ability to
     fulfill its commitment under this Agreement.

(h)  The Sub-Adviser shall review all proxy solicitation materials and be
     responsible for voting and handling all proxies in relation to the
     securities held in the Portfolio. The Adviser shall instruct the custodian
     and other parties providing services to the Portfolio to promptly forward
     misdirected proxies to the Sub-Adviser.

(i)  The Sub-Adviser will notify the Trust and the Adviser of any changes to the
     membership of the Sub-Adviser within a reasonable time after such change.

     Services to be furnished by the Sub-Adviser under this Agreement may be
     furnished through the medium of any of the Sub-Adviser's partners, officers
     or employees, or the officers or employees of the Sub-Adviser's general
     partner.

2.   DUTIES OF THE ADVISER. The Adviser shall continue to have responsibility
     for all services to be provided to the Portfolio pursuant to the Advisory
     Agreement and shall oversee and review the Sub-Adviser's performance of its
     duties under this Agreement; provided, however, that, in connection with
     its management of the Assets, nothing herein shall be construed to relieve
     the Sub-Adviser of responsibility for compliance with the applicable
     provisions of the Trust's Declaration of Trust (as defined herein), the
     applicable provisions of the Prospectus, the instructions and directions of
     the Board of Trustees of the Trust (subject to the provisions of Section
     l(b) hereunder), the applicable requirements of the 1940 Act, the
     applicable requirements of Subchapter M of the Internal Revenue Code of
     1986, and all other applicable federal and state laws and regulations, as
     each is amended from time to time.

3.   DELIVERY OF DOCUMENTS. The Adviser has furnished the Sub-Adviser with
     copies properly certified or authenticated of, and will furnish the
     Sub-Adviser with copies properly certified or authenticated of amendments
     and supplements to, each of the following documents:

     amended from time to time, herein called the "Declaration of Trust");

(b)  By-Laws of the Trust (such By-Laws, as in effect on the date of this
     Agreement and as amended from time to time, are herein called the
     "By-Laws");

4.   COMPENSATION TO THE SUB-ADVISER. For the services to be provided by the
     Sub-Adviser pursuant to this Agreement, the Adviser will pay the
     Sub-Adviser, and the Sub-Adviser agrees to accept as full compensation
     therefor, a sub-advisory tee at the rate specified in the Schedule(s) which
     is attached hereto and made part of this Agreement. The fee will be

     discretion and from time to time, waive a portion of its fee.

     shall be confined to those expressly set forth herein, and no implied

     omission in carrying out its duties hereunder, except a loss resulting from

     part in the performance of its obligations or duties, or from reckless
     disregard of its obligations or duties, under this Agreement, except as may
     otherwise be provided under provisions of applicable state law to the
     extent such provisions cannot be waived or modified hereby. The Adviser
     hereby acknowledges that it considers the Sub-Adviser to be a "corporate

     use thereof and not to use such materials if the Sub-Adviser reasonably
     objects in writing within five business days (or such other period as may
     be mutually agreed) after receipt thereof. The Sub-Adviser s right to
     object to such materials is limited to the portions of such materials that
     expressly relate to the Sub-Adviser, its services or its clients. The
     Adviser agrees to use its reasonable best efforts to ensure that materials

     Sub-Adviser, its services or its clients in any way are consistent with
     those materials previously approved by the Sub-Adviser as referenced in the
     first sentence of this paragraph. Sales literature may be furnished to the
     Sub-Adviser by first class or overnight mail, facsimile transmission
     equipment or hand delivery.

                        INVESTMENT SUB-ADVISORY AGREEMENT
                       SEI INSTITUTIONAL INVESTMENTS TRUST

     AGREEMENT made this 14th day of June, 1996, between SEI Financial
Management Corporation, (the "Adviser") and Wall Street Associates (the
"Sub-Adviser").

     WHEREAS, SEI Institutional Investments Trust, a Massachusetts business
trust (the "Trust") is registered as an open-end management investment company
under the Investment Company Act of 1940, as amended (the "1940 Act"); and

     WHEREAS, the Adviser has entered into an Investment Advisory Agreement 
dated June 14, 1996 (the "Advisory Agreement") with the Trust, pursuant to  
which the Adviser will act as investment adviser to the Small Cap Portfolio 
(the "Portfolio"), which is a series of the Trust; and

     WHEREAS, the Adviser, with the approval of the Trust, desires to retain 
the Sub-Adviser to provide investment advisory services to the Adviser in
connection with the management of the Portfolio, and the Sub-Adviser is willing
to render such investment advisory services.

     NOW, THEREFORE, the parties hereto agree as follows:

1.   DUTIES OF THE SUB-ADVISER. Subject to supervision by the Adviser and the
     Trust's Board of Trustees, the Sub-Adviser shall manage all of the
     securities and other assets of the Portfolio entrusted to it hereunder (the
     "Assets"), including the purchase, retention and disposition of the Assets,
     in accordance with the Portfolio's investment objectives, policies and
     restrictions as stated in the Portfolio's prospectus and statement of
     additional information, as currently in effect and as amended or
     supplemented from time to time (referred to collectively as the
     "Prospectus"), and subject to the following:

(a)  The Sub-Adviser shall, in consultation with and subject to the direction
     of the Adviser, determine from time to time.

(b)  In the performance of its duties and obligations under this Agreement, the
     Sub-Adviser shall act in conformity with the Trust's Declaration of Trust
     (as defined herein) and the Prospectus and with the instructions and
     directions of the Adviser and of the Board of Trustees of the Trust and
     will conform to and comply with the requirements of the 1940 Act, the
     Internal Revenue Code of 1986, and all other applicable federal and state
     laws and regulations, as each is amended from time to time.

(c)  The Sub-Adviser shall determine the Assets to be purchased or sold by the
     Portfolio as provided in subparagraph (a) and will place orders with or
     through such persons, brokers or dealers to carry out the policy with
     respect to brokerage set forth in the Portfolio's Registration Statement
     (as defined herein) and Prospectus or as the Board of Trustees or the
     Adviser may direct from time to time, in conformity with federal securities
     laws. In executing Portfolio transactions and selecting brokers or dealers,
     the Sub-Adviser will use its best efforts to seek on behalf of the
     Portfolio the best overall terms available. In assessing the best overall
     terms available for any transaction, the Sub-Adviser shall consider all
     factors that it deems relevant, including the breadth of the market in the
     security, the price of the security, the financial condition and execution
     capability of the broker or dealer, and the reasonableness of the
     commission, if any, both for the specific transaction and on a continuing
     basis. In evaluating the best overall terms available, and in selecting the
     broker-dealer to execute a particular transaction, the Sub-Adviser may also
     consider the brokerage and research services provided (as those terms are
     defined in Section 28(e) of the Securities Exchange Act of 1934).



<PAGE>


(d)  The Sub-Adviser shall maintain all books and records with respect to
     transactions involving the Assets required by subparagraphs (b)(5), (6),
     (7), (9), (10) and (11) and paragraph (f) of Rule 31a-1 under the 1940 Act.
     The Sub-Adviser shall provide to the Adviser or the Board of Trustees such
     periodic and special reports, balance sheets or financial information, and
     such other information with regard to its affairs as the Adviser or Board
     of Trustees may reasonably request.

     The Sub-Adviser shall keep the books and records relating to the Assets 
     required to be maintained by the Sub-Adviser under this Agreement and 
     shall timely furnish to the Adviser all information relating to the 
     Sub-Adviser's services under this Agreement needed by the Adviser to 
     keep the other books and records of the Portfolio required by Rule 31a-1 
     under the 1940 Act. The Sub-Adviser shall also furnish to the Adviser 
     any other information relating to the Assets that is required to be 
     filed by the Adviser or the Trust with the Securities and Exchange 
     Commission ("SEC") or sent to shareholders under the 1940 Act (including 
     the rules adopted thereunder) or any exemptive or other relief that the 
     Adviser or the Trust obtains from the SEC. The Sub-Adviser agrees that 
     all records that it maintains on behalf of the Portfolio are property of 
     the Portfolio and the Sub-Adviser will surrender promptly to the 
     Portfolio any of such records upon the Portfolio's request; provided, 
     however, that the Sub-Adviser may retain a copy of such records. In 
     addition, for the duration of this Agreement, the Sub-Adviser shall 
     preserve for the periods prescribed by Rule 31a-2 under the 1940 Act any 
     such records as are required to be maintained by it pursuant to this 
     Agreement, and shall transfer said records to any successor Sub-Adviser 
     upon the termination of his Agreement (or, if there is no successor 
     Sub-Adviser, to the Adviser).

(e)  The Sub-Adviser shall provide the Portfolio's custodian on each business 
     day with information relating to all transactions concerning the 
     Portfolio's Assets and shall provide the Adviser with such information 
     upon request of the Adviser.

(f)  The investment management services provided by the Sub-Adviser under this
     Agreement are not to be deemed exclusive and the Sub-Adviser shall be free
     to render similar services to others, as long as such services do not
     impair the services rendered to the Adviser or the Trust.

(g)  The Sub-Adviser shall promptly notify the Adviser of any financial
     condition that is likely to impair the Sub-Adviser's ability to fulfill its
     commitment under this Agreement.

(h)  The Sub-Adviser shall review all proxy solicitation materials and be
     responsible for voting and handling all proxies in relation to the
     securities held in the Portfolio. The Adviser shall instruct the custodian
     and other parties providing services to the Portfolio to promptly forward
     misdirected proxies to the Sub-Adviser.

     Services to be furnished by the Sub-Adviser under this Agreement may be
     furnished through the medium of any of the Sub-Adviser's partners, officers
     or employees.

2.   DUTIES OF THE ADVISER. The Adviser shall continue to have responsibility
     for all services to be provided to the Portfolio pursuant to the Advisory
     Agreement and shall oversee and review the Sub-Adviser's performance of its
     duties under this Agreement; provided, however, that in connection with its
     management of the Assets, nothing herein shall be construed to relieve the
     Sub-Adviser of responsibility for compliance with the Trust's Declaration
     of Trust (as defined herein), the Prospectus, the instructions and
     directions of the Board of Trustees of the Trust, the requirements of the
     1940 Act, the Internal Revenue Code of 1986, and all other applicable
     federal and state laws and regulations, as each is amended from time to
     time.

3.   DELIVERY OF DOCUMENTS. The Adviser has furnished the Sub-Adviser with
     copies properly certified or authenticated of each of the following
     documents:

(a)  The Trust's Agreement and Declaration of Trust, as filed with the Secretary
     of State of the Commonwealth of Massachusetts (such Agreement and
     Deciaration of Trust, as in effect on the date of this Agreement and as
     amended from time to time, herein called the "Declaration of Trust");

(b)  By-Laws of the Trust (such By-Laws, as in effect on the date of this
     Agreement and as amended from time to time, are herein called the
     "By-Laws");

(c)  Prospectus(es) of the Portfolio.

4.   COMPENSATION TO THE SUB-ADVISER. For the services to be provided by the
     Sub-Adviser pursuant to this Agreement, the Adviser will pay the
     Sub-Adviser, and the Sub-Adviser agrees to accept as full compensation
     therefor, a sub-advisory fee at the rate specified in the Schedule(s) which
     is attached hereto and made part of this Agreement. The fee will be
     calculated based on the average monthly market value of the Assets under
     the Sub-Adviser's management and will be paid to the Sub-Adviser monthly.
     Except as may otherwise be prohibited by law or regulation (including any
     then current SEC staff), the Sub-Adviser may, in its discretion and from
     time to time, waive a portion of its fee.

5.   LIMITATION OF LIABILITY OF THE SUB-ADVISER. The Sub-Adviser shall not be
     liable for any error of judgment or for any loss suffered by the Adviser in
     connection with the performance of its obligations under this Agreement,
     except a loss resulting from a breach of fiduciary duty with respect to the
     receipt of compensation for services (in which case any award of damages
     shall be limited to the period and the amount set forth in Section 36(b)(3)
     of the 1940 Act), or a loss resulting from willful misfeasance, bad faith
     or negligence on the Sub-Adviser's part in the performance of its duties or
     from reckless disregard of its obligations and duties under this Agreement,
     except as may otherwise be provided under provisions of applicable state
     law which cannot be waived or modified hereby.

6.   INDEMNIFICATION. The Sub-Adviser shall indemnify and hold harmless the
     Adviser from and against any and all claims, losses, liabilities or damages
     (including reasonable attorney's fees and other related expenses) howsoever
     arising from or in connection with the performance of the Sub-Adviser's
     obligations under this Agreement; the actions of the Sub-Adviser under this
     Agreement by the Sub-Adviser of its duties hereunder; provided, however,
     that the Sub-Adviser's obligation under this Section 6 shall be reduced to
     the extent that the claim against, or the loss, liability or damage
     experienced by the Adviser, is caused by or is otherwise directly related
     to the Adviser's own willful misfeasance, bad faith or negligence, or to
     the reckless disregard of its duties under this Agreement.

7.   DURATION AND TERMINATION. This Agreement shall become effective upon its
     approval by the Trust's Board of Trustees and by the vote of a majority of
     the outstanding voting securities of the Portfolio.

     This Agreement shall continue in effect for a period of more than two years

     Portfolio at any time, without the payment of any penalty, by the vote of a

     time, without the payment of any penalty, on 90 days' written notice to the

     principles; provided, however, that nothing herein shall be construed as

                         SEI INSTITUTIONAL lNVESTMENTS TRUST

    AGREEMENT made this 14th day of June 1996, between SEI Financial Management
Corporation, (the "Adviser") and Western Asset Management Company (the
"Sub-Adviser")

    WHEREAS, SEI Institutional Investments Trust, a Massachusetts business
trust (the "Trust") is registered as an open-end management investment company
under the Investment Company Act of 1940, as amended (the "1940 Act"); and

    WHEREAS, the Adviser has entered into an Investment Advisory Agreement
dated June 14, 1996 (the "Advisory Agreement") with the Trust, pursuant to which
the Adviser will act as investment adviser to the Core Fixed Income Portfolio
(the "Portfolio"), which is a series of the Trust; and

    WHEREAS the Adviser, with the approval of the Trust, desires to retain the
Sub-Adviser to provide investment advisory services to the Adviser in connection
with the management of the Portfolio, and the Sub-Adviser is willing to render
such investment advisory services.

    NOW, THEREFORE. the parties hereto agree as follows:

1.  DUTIES OF THE SUB-ADVISER. Subject to supervision by the Adviser and the
    Trust's Board of Trustees, the Sub-Adviser shall manage all of the
    securities and other assets of the Portfolio entrusted to it hereunder (the
    "Assets"), including the purchase, retention and disposition of the Assets,
    in accordance with the Portfolio's investment objectives, policies and
    restrictions as stated in the Portfolio's prospectus and statement of
    additional information, as currently in effect and as amended or
    supplemented from time to time (referred to collectively as the
    "Prospectus"), and subject to the following:

(a) The Sub-Adviser shall, subject to the Prospectus and any written
    instruction or direction of the Adviser, determine from time to time what
    Assets will be purchased, retained or sold by the Portfolio, and what
    portion of the Assets will be invested or held uninvested in cash.

(b) In the performance of its duties and obligations under this Agreement, the
    Sub-Adviser shall act in conformity with the Trust's Declaration of Trust
    (as defined herein) and the Prospectus and with the instructions and
    directions of the Adviser and of the Board of Trustees of the Trust and
    will conform to and comply with the requirements of the 1940 Act, the
    Internal Revenue Code of 1986, and all other applicable federal and state
    laws and regulations, as each is amended from time to time.

(c) The Sub-Adviser shall determine the Assets to be purchased or sold by the
    Portfolio as provided in subparagraph (a) and will place orders with or
    through such persons, brokers or dealers to carry out the policy with
    respect to brokerage set forth in the Portfolio's Registration Statement
    (as defined herein) and Prospectus or as the Board of Trustees or the
    Adviser may direct from time to time, in conformity with federal securities
    laws. In executing Portfolio transactions and selecting brokers or dealers,
    the Sub-Adviser will use its best efforts to seek on behalf of the
    Portfolio the best overall terms available.  In assessing the best overall
    terms available for any transaction, the Sub-Adviser shall consider all
    factors that it deems relevant, including the breadth of the market in the
    security, the price of the security, the financial condition and execution
    capability of the broker or dealer, and the reasonableness of the
    commission, if any, both for the specific transaction and on a continuing
    basis. In evaluating the best overall terms available, and in selecting the
    broker-dealer to execute a particular transaction, the Sub-Adviser may also
    consider the brokerage and research services provided (as those terms are
    defined in Section 28(e) of the Securities Exchange Act of 1934).
    Consistent with any guidelines established by the Board of Trustees of the
    Trust, the Sub-Adviser is authorized to pay to a broker or dealer who
    provides such brokerage and research services a commission for executing a
    portfolio transaction for the

<PAGE>

    Portfolio which is in excess of the amount of commission another broker or
    dealer would have charged for effecting that transaction if, but only if,
    the Sub-Adviser determines in good faith that such commission was
    reasonable in relation to the value of the brokerage and research services
    provided by such broker or dealer - - viewed in terms of that particular
    transaction or terms of the overall responsibilities of the Sub-Adviser to
    the Portfolio. In addition, the Sub-Adviser if authorized to allocate
    purchase and sale orders for securities to brokers or dealers (including
    brokers and dealers that are affiliated with the Adviser, Sub-Adviser or
    the Trust's principal underwriter) to take into account the sale of shares
    of the Trust if the Sub-Adviser believes that the quality of the
    transaction and the commission are comparable to what they would be with
    other qualified firms. In no instance, however, will the Portfolio's Assets
    be purchased from or sold to the Adviser, Sub-Adviser, the Trust's
    principal underwriter, or any affiliated person of either the Trust,
    Adviser, the Sub-Adviser or the principal underwriter, acting as principal
    in the transaction, except to the extent permitted by the Securities and
    Exchange Commission ("SEC") and the 1940 Act.

(d) The Sub-Adviser shall maintain all books and records with respect to
    transactions involving the Assets required by subparagraphs (b)(5), (6),
    (7), (9), (10) and (11) and paragraph (f) of Rule 31a-1 under the 1940
    Act. The Sub-Adviser shall provide to the Adviser or the Board of Trustees
    such periodic and special reports, balance sheets or financial information,
    and such other information with regard to its affairs as the Adviser or
    Board of Trustees may reasonably request.

    The Sub-Adviser shall keep the books and records relating to the Assets
    required to be maintained by the Sub-Adviser under this Agreement and shall
    timely furnish to the Adviser all information relating to the Sub-Adviser's
    services under this Agreement needed by the Adviser to keep the other books
    and records of the Portfolio required by Rule 31a-1 under the 1940 Act. The
    Sub-Adviser shall also furnish to the Adviser any other information
    relating to the Assets that is required to be filed by the Adviser or the
    Trust with the SEC or sent to shareholders under the 1940 Act (including
    the rules adopted thereunder) or any exemptive or other relief that the
    Adviser or the Trust obtains from the SEC. The Sub-Adviser agrees that all
    records that it maintains on behalf of the Portfolio are property of the
    Portfolio and the Sub-Adviser will surrender promptly to the Portfolio any
    of such records upon the Portfolio's request; provided however, that the
    Sub-Adviser may retain a copy of such records. In addition, for the
    duration of this Agreement, the Sub-Adviser shall preserve for the periods
    prescribed by Rule 31a-2 under the 1940 Act any such records as are
    required to be maintained by it pursuant to this Agreement, and shall
    transfer said records to any successor sub-adviser upon the termination of
    this Agreement (or, if there is no successor sub-adviser, to the Adviser).

(e) The Sub-Adviser shall provide the Portfolio's custodian on each business
    day with information relating to all transactions concerning the
    Portfolio's Assets and shall provide the Adviser with such information upon
    request of the Adviser.

(f) The investment management services provided by the Sub-Adviser under this
    Agreement are not to be deemed exclusive and the Sub-Adviser shall be free
    to render similar services to others, as long as such services do not
    impair the services rendered to the Adviser or the Trust.

(g) The Sub-Adviser shall promptly notify the Adviser of any financial
    condition that is likely to impair the Sub-Adviser's ability to fulfill its
    commitment under this Agreement.

(h) The Sub-Adviser shall review all proxy solicitation materials and be
    responsible for voting and handling all proxies in relation to the
    securities held in the Portfolio. The Adviser shall instruct the custodian
    and other parties providing services to the Portfolio to promptly forward
    misdirected proxies to the Sub-Adviser.

    for all services to be provided to the Portfolio pursuant to the Advisory
    Agreement and shall oversee and review the Sub-Adviser's performance of its
    duties under this Agreement; provided, however, that in connection with its
    management of the Assets, nothing herein shall be construed to relieve the
    Sub-Adviser of responsibility for compliance with the Trust's Declaration
    of Trust (as detained herein), the Prospectus, the instructions and
    directions of the Board of Trustees of the Trust, the requirements of the
    1940 Act, the Internal Revenue Code of 1986 and all other applicable
    federal and state laws and regulations, as each is amended from time to

    Declaration of Trust, as in effect on the date of this Agreement and as
    amended from time to time, herein called the "Declaration of Trust");

(b) By-Laws of the Trust (such By-Laws, as in effect on the date of this
    Agreement and as amended from time to time, are herein called the

4.  COMPENSATION TO THE SUB-ADVISER. For the services to be provided by the
    Sub-Adviser pursuant to this Agreement, the Adviser will pay the
    Sub-Adviser, and the Sub-Adviser agrees to accept as full compensation
    therefor, a sub-advisory fee at the rate specified in the Schedule(s) which
    is attached hereto and made part of this Agreement. The fee will be
    calculated based on the average monthly market value of the Assets under
    the Sub-Adviser's management and will be paid to the Sub-Adviser monthly
    Except as may otherwise be prohibited by law or regulation (including any
    then current SEC staff interpretation), the Sub-Adviser may, in its
    discretion and from time to time, waive a portion of its fee.

5.  INDEMNIFICATION. The Sub-Adviser shall indemnify and hold harmless the
    Adviser from and against any and all claims, losses, liabilities or damages
    (including reasonable attorney's fees and other related expenses) howsoever
    arising from or in connection with the performance of the Sub-Adviser's
    obligations under this Agreement; provided, however, that the Sub-Adviser's
    obligation under this Section 5 shall be reduced to the extent that the
    claim against, or the loss, liability or damage experienced by the Adviser,

    from or in connection with the performance of the Adviser's obligations
    under this Agreement; provided, however, that the Adviser's obligation

    misfeasance, bad faith or negligence, or to the reckless disregard of its

judgment or for any loss suffered by the Adviser in connection with performance

which case any award of damages shall be limited to the period and the amount
set forth in Section 36(b)(3) of the 1940 Act), or a loss resulting from willful
misfeasance, bad faith or negligence on the Sub-Adviser's part in the

    AGREEMENT made this 14th day of June, 1996, between SEI Financial
Management Corporation, (the "Adviser") and First of America Investment
Corporation (the "Sub-Adviser").

    WHEREAS, SEI Institutional Investments Trust, a Massachusetts business
trust (the "Trust") is registered as an open-end management investment company
under the Investment Company Act of 1940, as amended (the "1940  Act"); and

    WHEREAS, the Adviser has entered into an Investment Advisory Agreement
dated December 16, 1994 (the "Advisory Agreement") with the Trust, pursuant to
which the Adviser will act as investment adviser to the Small Cap Growth
Portfolio (the "Portfolio"), which is a series of the Trust; and

    WHEREAS, the Adviser, with the approval of the Trust, desires to retain the
Sub-Adviser to provide investment advisory services to the Adviser in connection
with the management of the Portfolio, and the Sub-Adviser is willing to render
such investment advisory services.

    NOW, THEREFORE, the parties hereto agree as follows:

1.  DUTIES OF THE SUB-ADVISER.  Subject to supervision by the Adviser and the
    Trust's Board of Trustees, the Sub-Adviser shall manage all of the
    securities and other assets of the Portfolio entrusted to it hereunder (the
    "Assets"), including the purchase, retention and disposition of the Assets,
    in accordance with the Portfolio's investment objectives, policies and
    restrictions as stated in the Portfolio's prospectus and statement of
    additional information,  as currently in effect and as amended or
    supplemented from time to time (referred to collectively as the
    "Prospectus"), and subject to the following:

(a) The Sub-Adviser shall, in consultation with and subject to the direction of
    the Adviser, determine from time to time what Assets will be purchased,
    retained or sold by the Portfolio, and what portion of the Assets will be
    invested or held uninvested in cash.

(b) In the performance of its duties and obligations under this Agreement, the
    Sub-Adviser shall act in conformity with the Trust's Declaration of Trust
    (as defined herein) and the Prospectus and with the instructions and
    directions of the Adviser and of the Board of Trustees of the Trust and
    will conform to and comply with the requirements of the 1940 Act, the
    Internal Revenue Code of 1986, and all other applicable federal and state
    laws and regulations, as each is amended from time to time.

(c) The Sub-Adviser shall determine the Assets to be purchased or sold by the
    Portfolio as provided in subparagraph (a) and will place orders with or
    through such persons, brokers or dealers to carry out the policy with
    respect to brokerage set forth in the Portfolio's Registration Statement
    (as defined herein) and Prospectus or as the Board of Trustees or the
    Adviser may direct from time to time, in conformity with federal securities
    laws.  In executing Portfolio transactions and selecting brokers or
    dealers, the Sub-Adviser will use its best efforts to seek on behalf of the
    Portfolio the best overall terms available.  In assessing the best overall
    terms available for any transaction, the Sub-Adviser shall consider all
    factors that it deems relevant, including the breadth of the market in the
    security, the price of the security, the financial condition and execution
    capability of the broker

<PAGE>

    or dealer, and the reasonableness of the commission, if any, both for the
    specific transaction and on a continuing basis.  In evaluating the best
    overall terms available, and in selecting the broker-dealer to execute a
    particular transaction, the Sub-Adviser may also consider the brokerage and
    research services provided (as those terms are defined in Section 28(e) of
    the Securities Exchange Act of 1934).  Consistent with any guidelines
    established by the Board of Trustees of the Trust, the Sub-Adviser is
    authorized to pay to a broker or dealer who provides such brokerage and
    research services a commission for executing a portfolio transaction for
    the Portfolio which is in excess of the amount of commission another broker
    or dealer would have charged for effecting that transaction if, but only
    if, the Sub-Adviser determines in good faith that such commission was
    reasonable in relation to the value of the brokerage and research services
    provided by such broker or dealer - - viewed in terms of that particular
    transaction or terms of the overall responsibilities of the Sub-Adviser to
    the Portfolio.  In addition, the Sub-Adviser is authorized to allocate
    purchase and sale orders for securities to brokers or dealers (including
    brokers and dealers that are affiliated with the Adviser, Sub-Adviser or
    the Trust's principal underwriter) to take into account the sale of shares
    of the Trust if the Sub-Adviser believes that the quality of the
    transaction and the commission are comparable to what they would be with
    other qualified firms.  In no instance, however, will the Portfolio's
    Assets be purchased from or sold to the Adviser, Sub-Adviser, the Trust's
    principal underwriter, or any affiliated person of either the Trust,
    Adviser, the Sub-Adviser or the principal underwriter, acting as principal
    in the transaction, except to the extent permitted by the Securities and
    Exchange Commission ("SEC") and the 1940 Act.

(d) The Sub-Adviser shall maintain all books and records with respect to
    transactions involving the Assets required by subparagraphs (b)(5), (6),
    (7), (9), (10) and (11) and paragraph (f) of Rule 31a-1 under the 1940 Act.
    The Sub-Adviser shall provide to the Adviser or the Board of Trustees such
    periodic and special reports, balance sheets or financial information, and
    such other information with regard to its affairs as the Adviser or Board
    of Trustees may reasonably request.

    The Sub-Adviser shall keep the books and records relating to the Assets
    required to be maintained by the Sub-Adviser under this Agreement and shall
    timely furnish to the Adviser all information relating to the Sub-Adviser's
    services under this Agreement needed by the Adviser to keep the other books
    and records of the Portfolio required by Rule 31a-1 under the 1940 Act.
    The Sub-Adviser shall also furnish to the Adviser any other information
    relating to the Assets that is required to be filed by the Adviser or the
    Trust with the SEC or sent to shareholders under the 1940 Act (including
    the rules adopted thereunder) or any exemptive or other relief that the
    Adviser or the Trust obtains from the SEC.  The Sub-Adviser agrees that all
    records that it maintains on behalf of the Portfolio are property of the
    Portfolio and the Sub-Adviser will surrender promptly to the Portfolio any
    of such records upon the Portfolio's request; provided, however, that the
    Sub-Adviser may retain a copy of such records.  In addition, for the
    duration of this Agreement, the  Sub-Adviser shall preserve for the periods
    prescribed by Rule  31a-2 under the 1940 Act any such records as are
    required to be maintained by it pursuant to this Agreement, and shall
    transfer said records to any successor sub-adviser upon the termination of
    this Agreement (or, if there is no successor sub-adviser, to the Adviser).

(e) The Sub-Adviser shall provide the Portfolio's custodian on each business
    day with information relating to all transactions concerning the
    Portfolio's Assets and shall provide the Adviser with such information upon
    request of the Adviser.

(f) The investment management services provided by the Sub-Adviser under this

    to render similar services to others, as long as such services do not
    impair the services rendered to the Adviser or the Trust.

    for all services to be provided to the Portfolio pursuant to the Advisory
    Agreement and shall oversee and review the Sub-Adviser's performance of its
    duties under this Agreement; provided, however, that in connection with its
    management of the Assets, nothing herein shall be construed to relieve the
    Sub-Adviser of responsibility for compliance with the Trust's Declaration
    of Trust (as defined herein), the Prospectus, the instructions and
    directions of the Board of Trustees of the Trust, the requirements of the
    1940 Act, the Internal Revenue Code of 1986, and all other applicable
    federal and state laws and regulations, as each is amended from time to
    time.

    copies properly certified or authenticated of each of the following
    documents:

    Sub-Adviser, and the Sub-Adviser agrees to accept as full compensation
    therefor, a sub-advisory fee at the rate specified in the Schedule(s) which

    the Sub-Adviser's management and will be paid to the Sub-Adviser monthly.

    then current SEC staff interpretation), the Sub-Adviser may, in its
    discretion and from time to time, waive a portion of its fee.

5.  INDEMNIFICATION.  The Sub-Adviser shall indemnify and hold harmless the
    Adviser from and against any and all claims, losses, liabilities or damages
    (including reasonable attorney's fees and other related expenses) howsoever
    arising from or in connection with the performance of the Sub-Adviser's
    obligations under this Agreement; provided, however, that the Sub-Adviser's
    obligation under this Section 5 shall be reduced to the extent that the
    claim against, or the loss, liability or damage experienced by the Adviser,
    is caused by or is otherwise directly related to the Adviser's own, or any
    other sub-adviser's, willful misfeasance, bad faith or negligence, or to
    the reckless disregard of its duties under this Agreement.

6.  DURATION AND TERMINATION.  This Agreement shall become effective upon its
    approval by the Trust's Board of Trustees and by the vote of a majority of
    the outstanding voting securities of the Portfolio.  This Agreement shall

    only so long as continuance is specifically approved at least annually in
    conformance with the 1940 Act; provided, however, that this Agreement may

    the payment of any penalty, on not more than 60 days' nor less than 30
    days' written notice to the Sub-Adviser, or (c) by the Sub-Adviser at any
    time, without the payment of any penalty, on 90 days' written notice to the
    Adviser.  This Agreement shall terminate automatically and immediately in
    the event of its assignment, or in the event of a termination of the
    Adviser's agreement with the Trust.  As used in this Section 6, the terms
    "assignment" and "vote of a majority of the outstanding voting securities"
    shall have the respective meanings set forth in the 1940 Act and the rules
    and regulations thereunder, subject to such exceptions as may be granted by
    the SEC under the 1940 Act.

7.  GOVERNING LAW.  This Agreement shall be governed by the internal laws of

    principles; provided, however, that nothing herein shall be construed as
    being inconsistent with the 1940 Act.

8.  SEVERABILITY.  Should any part of this Agreement be held invalid by a court
    decision, statute, rule or otherwise, the remainder of this Agreement shall
    not be affected thereby.  This Agreement shall be binding upon and shall
    inure to the benefit of the parties hereto and their respective successors.

                         SEI INSTITUTIONAL INVESTMENTS TRUST

    AGREEMENT made this 14th day of June, 1996, between SEI Financial
Management Corporation, (the "Adviser") and Farrell Wako Global Investment
Management, Inc. (the "Sub-Adviser").

    WHEREAS, SEI Institutional Investments Trust, a Massachusetts business
trust (the "Trust") is registered as an open-end management investment company
under the Investment Company Act of 1940, as amended (the "1940  Act"); and

    WHEREAS, the Adviser has entered into an Investment Advisory Agreement
dated June 14, 1996 (the "Advisory Agreement") with the Trust, pursuant to which
the Adviser will act as investment adviser to the International Equity Portfolio
(the "Portfolio"), which is a series of the Trust; and

    WHEREAS, the Adviser, with the approval of the Trust, desires to retain the
Sub-Adviser to provide investment advisory services to the Adviser in connection
with the management of the Portfolio, and the Sub-Adviser is willing to render
such investment advisory services.

    NOW, THEREFORE, the parties hereto agree as follows:

1.  DUTIES OF THE SUB-ADVISER.  Subject to supervision by the Adviser and the
    Trust's Board of Trustees, the Sub-Adviser shall manage all of the
    securities and other assets of the Portfolio entrusted to it hereunder (the
    "Assets"), including the purchase, retention and disposition of the Assets,
    in accordance with the Portfolio's investment objectives, policies and
    restrictions as stated in the Portfolio's prospectus and statement of
    additional information,  as currently in effect and as amended or
    supplemented from time to time (referred to collectively as the
    "Prospectus"), and subject to the following:

(a) The Sub-Adviser shall, in consultation with and subject to the direction of
    the Adviser, determine from time to time what Assets will be purchased,
    retained or sold by the Portfolio, and what portion of the Assets will be
    invested or held uninvested in cash.

(b) In the performance of its duties and obligations under this Agreement, the
    Sub-Adviser shall act in conformity with the Trust's Declaration of Trust
    (as defined herein) and the Prospectus and with the instructions and
    directions of the Adviser and of the Board of Trustees of the Trust and
    will conform to and comply with the requirements of the 1940 Act, the
    Internal Revenue Code of 1986, and all other applicable federal and state
    laws and regulations, as each is amended from time to time.

(c) The Sub-Adviser shall determine the Assets to be purchased or sold by the
    Portfolio as provided in subparagraph (a) and will place orders with or
    through such persons, brokers or dealers to carry out the policy with
    respect to brokerage set forth in the Portfolio's Registration Statement
    (as defined herein) and Prospectus or as the Board of Trustees or the
    Adviser may direct from time to time, in conformity with federal securities
    laws.  In executing Portfolio transactions and selecting brokers or
    dealers, the Sub-Adviser will use its best efforts to seek on behalf of the
    Portfolio the best overall terms available.  In assessing the best overall
    terms available for any transaction, the Sub-Adviser shall consider all
    factors that it deems relevant, including the breadth of the market in the
    security, the price of the security, the financial condition and execution
    capability of the broker or dealer, and the reasonableness of the
    commission, if any, both for the specific transaction and on a continuing
    basis.  In evaluating the best overall terms available, and in selecting
    the broker-dealer to execute a particular transaction, the Sub-Adviser may
    also consider the brokerage and research services provided (as those terms
    are defined in Section 28(e) of the Securities Exchange Act of 1934).
    Consistent with any guidelines established by the Board of Trustees of the
    Trust, the Sub-Adviser is authorized to pay to a broker or dealer who
    provides such brokerage and research services a commission for executing a
    portfolio transaction for the

<PAGE>

    Portfolio which is in excess of the amount of commission another broker or
    dealer would have charged for effecting that transaction if, but only if,
    the Sub-Adviser determines in good faith that such commission was
    reasonable in relation to the value of the brokerage and research services
    provided by such broker or dealer - - viewed in terms of that particular
    transaction or terms of the overall responsibilities of the Sub-Adviser to
    the Portfolio.  In addition, the Sub-Adviser is authorized to allocate
    purchase and sale orders for securities to brokers or dealers (including
    brokers and dealers that are affiliated with the Adviser, Sub-Adviser or
    the Trust's principal underwriter) to take into account the sale of shares
    of the Trust if the Sub-Adviser believes that the quality of the
    transaction and the commission are comparable to what they would be with
    other qualified firms.  In no instance, however, will the Portfolio's
    Assets be purchased from or sold to the Adviser, Sub-Adviser, the Trust's
    principal underwriter, or any affiliated person of either the Trust,
    Adviser, the Sub-Adviser or the principal underwriter, acting as principal
    in the transaction, except to the extent permitted by the Securities and
    Exchange Commission ("SEC") and the 1940 Act.

(d) The Sub-Adviser shall maintain all books and records with respect to
    transactions involving the Assets required by subparagraphs (b)(5), (6),
    (7), (9), (10) and (11) and paragraph (f) of Rule 31a-1 under the 1940 Act.
    The Sub-Adviser shall provide to the Adviser or the Board of Trustees such
    periodic and special reports, balance sheets or financial information, and
    such other information with regard to its affairs as the Adviser or Board
    of Trustees may reasonably request.

    The Sub-Adviser shall keep the books and records relating to the Assets
    required to be maintained by the Sub-Adviser under this Agreement and shall
    timely furnish to the Adviser all information relating to the Sub-Adviser's
    services under this Agreement needed by the Adviser to keep the other books
    and records of the Portfolio required by Rule 31a-1 under the 1940 Act.
    The Sub-Adviser shall also furnish to the Adviser any other information
    relating to the Assets that is required to be filed by the Adviser or the
    Trust with the SEC" or sent to shareholders under the 1940 Act (including
    the rules adopted thereunder) or any exemptive or other relief that the
    Adviser or the Trust obtains from the SEC.  The Sub-Adviser agrees that all
    records that it maintains on behalf of the Portfolio are property of the
    Portfolio and the Sub-Adviser will surrender promptly to the Portfolio any
    of such records upon the Portfolio's request; provided, however, that the
    Sub-Adviser may retain a copy of such records.  In addition, for the
    duration of this Agreement, the  Sub-Adviser shall preserve for the periods
    prescribed by Rule  31a-2 under the 1940 Act any such records as are
    required to be maintained by it pursuant to this Agreement, and shall
    transfer said records to any successor sub-adviser upon the termination of
    this Agreement (or, if there is no successor sub-adviser, to the Adviser).

(e) The Sub-Adviser shall provide the Portfolio's custodian on each business
    day with information relating to all transactions concerning the
    Portfolio's Assets and shall provide the Adviser with such information upon
    request of the Adviser.

(f) The investment management services provided by the Sub-Adviser under this
    Agreement are not to be deemed exclusive and the Sub-Adviser shall be free
    to render similar services to others, as long as such services do not
    impair the services rendered to the Adviser or the Trust.

(g) The Sub-Adviser shall promptly notify the Adviser of any financial
    condition that is likely to impair the Sub-Adviser's ability to fulfill its
    commitment under this Agreement.

(h) The Sub-Adviser shall review all proxy solicitation materials and be
    responsible for voting and handling all proxies in relation to the
    securities held in the Portfolio.  The Adviser shall instruct the custodian
    and other parties providing services to the Portfolio to promptly forward
    misdirected proxies to the Sub-Adviser.

    furnished through the medium of any of the Sub-Adviser's partners, officers
    or employees.

    for all services to be provided to the Portfolio pursuant to the Advisory
    Agreement and shall oversee and review the Sub-Adviser's performance of its
    duties under this Agreement; provided, however, that in connection with its
    management of the Assets, nothing herein shall be construed to relieve the
    Sub-Adviser of responsibility for compliance with the Trust's Declaration
    of Trust (as defined herein), the Prospectus, the instructions and
    directions of the Board of Trustees of the Trust, the requirements of the
    1940 Act, the Internal Revenue Code of 1986, and all other applicable

    Agreement and as amended from time to time, are herein called the
    "By-Laws");

(c) Prospectus(es) of the Portfolio.

4.  COMPENSATION TO THE SUB-ADVISER.  For the services to be provided by the
    Sub-Adviser pursuant to this Agreement, the Adviser will pay the
    Sub-Adviser, and the Sub-Adviser agrees to accept as full compensation
    therefor, a sub-advisory fee at the rate specified in the Schedule(s) which
    is attached hereto and made part of this Agreement.  The fee will be
    calculated based on the average monthly market value of the Assets under

    Except as may otherwise be prohibited by law or regulation (including any
    then current SEC staff interpretation), the Sub-Adviser may, in its
    discretion and from time to time, waive a portion of its fee.

5.  INDEMNIFICATION.  The Sub-Adviser shall indemnify and hold harmless the
    Adviser from and against any and all claims, losses, liabilities or damages
    (including reasonable attorney's fees and other related expenses) howsoever
    arising from or in connection with the performance of the Sub-Adviser s
    obligations under this Agreement; provided, however, that the Sub-Adviser s
    obligation under this Section 5 shall be reduced to the extent that the

                          INVESTMENT SUB-ADVISORY AGREEMENT
                         SEI INSTITUTIONAL INVESTMENTS TRUST

    AGREEMENT made this 14th day of June, 1996, between SEI Financial
Management Corporation, (the "Adviser") and Seligman Henderson Co. (the
"Sub-Adviser").

    WHEREAS, SEI Institutional Investments Trust, a Massachusetts business
trust (the "Trust") is registered as an open-end management investment company
under the Investment Company Act of 1940, as amended (the "1940  Act"); and

    WHEREAS, the Adviser has entered into an Investment Advisory Agreement
dated June 14, 1996 (the "Advisory Agreement") with the Trust, pursuant to which
the Adviser will act as investment adviser to the International Equity Portfolio
(the "Portfolio"), which is a series of the Trust; and

    WHEREAS, the Adviser, with the approval of the Trust, desires to retain the
Sub-Adviser to provide investment advisory services to the Adviser in connection
with the management of the Portfolio, and the Sub-Adviser is willing to render
such investment advisory services.

    NOW, THEREFORE, the parties hereto agree as follows:

1.  DUTIES OF THE SUB-ADVISER.  Subject to supervision by the Adviser and the
    Trust's Board of Trustees, the Sub-Adviser shall manage all of the
    securities and other assets of the Portfolio entrusted to it hereunder (the
    "Assets"), including the purchase, retention and disposition of the Assets,
    in accordance with the Portfolio's investment objectives, policies and
    restrictions as stated in the Portfolio's prospectus and statement of
    additional information,  as currently in effect and as amended or
    supplemented from time to time (referred to collectively as the
    "Prospectus"), and subject to the following:

(a) The Sub-Adviser shall, in consultation with and subject to the direction of
    the Adviser, determine from time to time what Assets will be purchased,
    retained or sold by the Portfolio, and what portion of the Assets will be
    invested or held uninvested in cash.

(b) In the performance of its duties and obligations under this Agreement, the
    Sub-Adviser shall act in conformity with the Trust's Declaration of Trust
    (as defined herein) and the Prospectus and with the instructions and
    directions of the Adviser and of the Board of Trustees of the Trust and
    will conform to and comply with the requirements of the 1940 Act, the
    Internal Revenue Code of 1986, and all other applicable federal and state
    laws and regulations, as each is amended from time to time.

(c) The Sub-Adviser shall determine the Assets to be purchased or sold by the
    Portfolio as provided in subparagraph (a) and will place orders with or
    through such persons, brokers or dealers to carry out the policy with
    respect to brokerage set forth in the Portfolio's Registration Statement
    (as defined herein) and Prospectus or as the Board of Trustees or the
    Adviser may direct from time to time, in conformity with federal securities
    laws.  In executing Portfolio transactions and selecting brokers or
    dealers, the Sub-Adviser will use its best efforts to seek on behalf of the
    Portfolio the best execution.  In assessing the best execution availability
    for each transaction, the Sub-Adviser shall consider all factors that it
    deems relevant, including the breadth of the market in the security, the
    price of the security, the financial condition and execution and
    operational capability of the broker or dealer, and the reasonableness of
    the commission, if any, both for the specific transaction and on a
    continuing basis.  In evaluating the best execution, and in selecting

<PAGE>

    the broker-dealer to execute a particular transaction, the Sub-Adviser may
    also consider the brokerage and research services provided (as those terms
    are defined in Section 28(e) of the Securities Exchange Act of 1934).
    Consistent with any guidelines established by the Board of Trustees of the
    Trust, the Sub-Adviser is authorized to pay to a broker or dealer who
    provides such brokerage and research services a commission for executing a
    portfolio transaction for the Portfolio which is in excess of the amount of
    commission another broker or dealer would have charged for effecting that
    transaction if, but only if, the Sub-Adviser determines in good faith that
    such commission was reasonable in relation to the value of the brokerage
    and research services provided by such broker or dealer - - viewed in terms
    of that particular transaction or terms of the overall responsibilities of
    the Sub-Adviser to the Portfolio and its other clients.  In addition, the
    Sub-Adviser is authorized to allocate purchase and sale orders for
    securities to brokers or dealers (including brokers and dealers that are
    affiliated with the Adviser, Sub-Adviser or the Trust's principal
    underwriter) to take into account the sale of shares of the Trust if the
    Sub-Adviser believes that the quality of the transaction and the commission
    are comparable to what they would be with other qualified firms.  In no
    instance, however, will the Portfolio's Assets be purchased from or sold to
    the Adviser, Sub-Adviser, the Trust's principal underwriter, or any
    affiliated person of either the Trust, Adviser, the Sub-Adviser or the
    principal underwriter, acting as principal in the transaction, except to
    the extent permitted by the Securities and Exchange Commission ("SEC") and
    the 1940 Act.

(d) The Sub-Adviser shall maintain all books and records with respect to
    transactions involving the Assets required by subparagraphs (b)(5), (6),
    (7), (9), (10) and (11) and paragraph (f) of Rule 31a-1 under the 1940 Act.
    The Sub-Adviser shall provide to the Adviser or the Board of Trustees such
    periodic and special reports, balance sheets or financial information, and
    such other information with regard to its affairs as the Adviser or Board
    of Trustees may reasonably request.

    The Sub-Adviser shall keep the books and records relating to the Assets
    required to be maintained by the Sub-Adviser under this Agreement and shall
    timely furnish to the Adviser all information relating to the Sub-Adviser's
    services under this Agreement needed by the Adviser to keep the other books
    and records of the Portfolio required by Rule 31a-1 under the 1940 Act.
    The Sub-Adviser shall also furnish to the Adviser any other information
    relating to the Assets that is required to be filed by the Adviser or the
    Trust with the SEC or sent to shareholders under the 1940 Act (including
    the rules adopted thereunder) or any exemptive or other relief that the
    Adviser or the Trust obtains from the SEC.  The Sub-Adviser agrees that all
    records that it maintains on behalf of the Portfolio are property of the
    Portfolio and the Sub-Adviser will surrender promptly to the Portfolio any
    of such records upon the Portfolio's request; provided, however, that the
    Sub-Adviser may retain a copy of such records.  In addition, for the
    duration of this Agreement, the  Sub-Adviser shall preserve for the periods
    prescribed by Rule  31a-2 under the 1940 Act any such records as are
    required to be maintained by it pursuant to this Agreement, and shall
    transfer said records to any successor sub-adviser upon the termination of
    this Agreement (or, if there is no successor sub-adviser, to the Adviser).

(e) The Sub-Adviser shall provide the Portfolio's custodian on each business
    day with information relating to all transactions concerning the
    Portfolio's Assets and shall provide the Adviser with such information upon
    request of the Adviser.

(f) The investment management services provided by the Sub-Adviser under this
    Agreement are not to be deemed exclusive and the Sub-Adviser shall be free
    to render similar services to others, as long as such services do not
    impair the services rendered to the Adviser or the Trust.

(g) The Sub-Adviser shall promptly notify the Adviser of any financial
    condition that is likely to impair the Sub-Adviser's ability to fulfill its
    commitment under this Agreement.


                                          2

(h) The Sub-Adviser shall review all proxy solicitation materials and be
    responsible for voting and handling all proxies in relation to the
    securities held in the Portfolio.  The Adviser shall instruct the custodian
    and other parties providing services to the Portfolio to promptly forward
    misdirected proxies to the Sub-Adviser.

    Services to be furnished by the Sub-Adviser under this Agreement may be
    furnished through the medium of any of the Sub-Adviser's partners,
    officers, employees or affiliates.

2.  DUTIES OF THE ADVISER.  The Adviser shall continue to have responsibility
    for all services to be provided to the Portfolio pursuant to the Advisory
    Agreement and shall oversee and review the Sub-Adviser's performance of its
    duties under this Agreement; provided, however, that in connection with its
    management of the Assets, nothing herein shall be construed to relieve the
    Sub-Adviser of responsibility for compliance with the Trust's Declaration
    of Trust (as defined herein), the Prospectus, the instructions and
    directions of the Board of Trustees of the Trust, the requirements of the
    1940 Act, the Internal Revenue Code of 1986, and all other applicable
    federal and state laws and regulations, as each is amended from time to
    time.

3.  DELIVERY OF DOCUMENTS.  The Adviser has furnished the Sub-Adviser with
    copies properly certified or authenticated of each of the following
    documents:

(a) The Trust's Agreement and Declaration of Trust, as filed with the Secretary
    of State of the Commonwealth of Massachusetts (such Agreement and
    Declaration of Trust, as in effect on the date of this Agreement and as
    amended from time to time, herein called the "Declaration of Trust");

(b) By-Laws of the Trust (such By-Laws, as in effect on the date of this
    Agreement and as amended from time to time, are herein called the
    "By-Laws");

(c) Prospectus(es) of the Portfolio.

    The Adviser will promptly furnish to the Sub-Adviser any and all amendments
    or other changes to the documents specified in this Section 3, and the
    Sub-Adviser shall not be charged with complying with any such document or
    amendment not so delivered to the Sub-Adviser, unless the Sub-Adviser
    reasonably should have known the terms of such document or amendment.

4.  COMPENSATION TO THE SUB-ADVISER.  For the services to be provided by the
    Sub-Adviser pursuant to this Agreement, the Adviser will pay the
    Sub-Adviser, and the Sub-Adviser agrees to accept as full compensation
    therefor, a sub-advisory fee at the rate specified in the Schedule(s) which
    is attached hereto and made part of this Agreement.  The fee will be
    calculated based on the average monthly market value of the Assets under
    the Sub-Adviser's management and will be paid to the Sub-Adviser monthly.
    Except as may otherwise be prohibited by law or regulation (including any
    then current SEC staff interpretation), the Sub-Adviser may, in its
    discretion and from time to time, waive a portion of its fee.

5.  INDEMNIFICATION.  The Sub-Adviser shall indemnify and hold harmless the
    Adviser from and against any and all claims, losses, liabilities or damages
    (including reasonable attorney's fees and other related expenses) howsoever
    arising from or in connection with the performance of the Sub-Adviser's
    obligations under this Agreement; provided, however, that the Sub-Adviser's
    obligation under this Section 5 shall be reduced to the extent that the
    claim against, or the loss, liability or damage experienced by the Adviser,
    is caused by or is otherwise directly related to the Adviser's own willful
    misfeasance, bad faith or negligence, or to the reckless disregard of its
    duties under this Agreement.

6.  DURATION AND TERMINATION.  This Agreement shall become effective upon its
    approval by the Trust's Board of Trustees and by the vote of a majority of
    the outstanding voting securities of the Portfolio.  This Agreement shall
    continue in effect for a period of more than two years from the date hereof
    only so long as continuance is specifically approved at least annually in
    conformance with the 1940 Act; provided, however, that this Agreement may
    be terminated with respect to the Portfolio (a) by the Portfolio at any
    time, without the payment of any penalty, by the vote of a majority of

    days' written notice to the Sub-Adviser, or (c) by the Sub-Adviser at any

    Adviser.  This Agreement shall terminate automatically and immediately in
    the event of its assignment, or in the event of a termination of the
    Adviser's agreement with the Trust.  As used in this Section 6, the terms
    "assignment" and "vote of a majority of the outstanding voting securities"
    shall have the respective meanings set forth in the 1940 Act and the rules
    and regulations thereunder, subject to such exceptions as may be granted by
    the SEC under the 1940 Act.

7.  GOVERNING LAW.  This Agreement shall be governed by the internal laws of
    the Commonwealth of Massachusetts, without regard to conflict of law
    principles; provided, however, that nothing herein shall be construed as
    being inconsistent with the 1940 Act.

8.  SEVERABILITY.  Should any part of this Agreement be held invalid by a court
    decision, statute, rule or otherwise, the remainder of this Agreement shall
    not be affected thereby.  This Agreement shall be binding upon and shall

                         SEI INSTITUTIONAL INVESTMENTS TRUST

    AGREEMENT made this 20th day of September, 1996, between SEI Investments
Management Corporation, (the "Adviser") and Furman Selz Capital Management, LLC
(the "Sub-Adviser").

    WHEREAS, SEI Institutional Investments Trust, a Massachusetts business
trust (the "Trust"), is registered as an open-end management investment company
under the Investment Company Act of 1940, as amended (the "1940  Act"); and

    WHEREAS, the Adviser has entered into an Investment Advisory Agreement
dated June 14, 1996  (the "Advisory Agreement") with the Trust, pursuant to
which the Adviser will act as investment adviser to the Small Cap Growth Fund

    WHEREAS, the Adviser, with the approval of the Trust, desires to retain the
Sub-Adviser to provide investment advisory services to the Adviser in connection
with the management of the Portfolio, and the Sub-Adviser is willing to render
such investment advisory services.

    NOW, THEREFORE, the parties hereto agree as follows:

1.  DUTIES OF THE SUB-ADVISER.  Subject to supervision by the Adviser and the
    Trust's Board of Trustees, the Sub-Adviser shall manage all of the
    securities and other assets of the Portfolio entrusted to it hereunder (the
    "Assets"), including the purchase, retention and disposition of the Assets,
    in accordance with the Portfolio's investment objectives, policies and
    restrictions as stated in the Portfolio's prospectus and statement of
    additional information,  as currently in effect and as amended or
    supplemented from time to time (referred to collectively as the
    "Prospectus"), and subject to the following:

(a) The Sub-Adviser shall, in consultation with and subject to the direction of
    the Adviser, determine from time to time what Assets will be purchased,
    retained or sold by the Portfolio, and what portion of the Assets will be
    invested or held uninvested in cash.

(b) In the performance of its duties and obligations under this Agreement, the
    Sub-Adviser shall act in conformity with the Trust's Declaration of Trust
    (as defined herein) and the Prospectus and with the instructions and
    directions of the Adviser and of the Board of Trustees of the Trust and
    will conform to and comply with the requirements of the 1940 Act, the
    Internal Revenue Code of 1986, and all other applicable federal and state
    laws and regulations, as each is amended from time to time.

(c) The Sub-Adviser shall determine the Assets to be purchased or sold by the
    Portfolio as provided in subparagraph (a) and will place orders with or
    through such persons, brokers or dealers to carry out the policy with
    respect to brokerage set forth in the Portfolio's Registration Statement
    (as defined herein) and Prospectus or as the Board of Trustees or the
    Adviser may direct from time to time, in conformity with federal securities
    laws.  In executing Portfolio transactions and selecting brokers or
    dealers, the Sub-Adviser will use its best efforts to seek on behalf of the
    Portfolio the best overall terms available.  In assessing the best overall
    terms available for any transaction, the Sub-Adviser shall consider all
    factors that it deems relevant, including the breadth of the market in the
    security, the price of the security, the financial condition and execution
    capability of the broker or dealer, and the reasonableness of the
    commission, if any, both for the specific transaction and on a continuing
    basis.  In evaluating the best overall terms available, and in selecting
    the broker-dealer to execute a particular transaction, the Sub-Adviser may
    also consider the brokerage and research services provided (as those terms
    are defined in Section 28(e) of the Securities Exchange Act of 1934).

    Trust, the Sub-Adviser is authorized to pay to a broker or dealer who

    Adviser, Sub-Adviser or the Trust's principal underwriter) to take into
    account the sale of shares of the Trust if the Sub-Adviser believes that
    the quality of the transaction and the commission are comparable to what
    they would be with other qualified firms.  In no instance, however, will
    the Portfolio's Assets be purchased from or sold to the Adviser,
    Sub-Adviser, the Trust's principal underwriter, or any affiliated person of
    either the Trust, Adviser, the Sub-Adviser or the principal underwriter,
    acting as principal in the transaction, except to the extent permitted by
    the Securities and Exchange Commission ("SEC") and the 1940 Act.

(d) The Sub-Adviser shall maintain all books and records with respect to
    transactions involving the Assets required by subparagraphs (b)(5), (6),

    The Sub-Adviser shall provide to the Adviser or the Board of Trustees such
    periodic and special reports, balance sheets or financial information, and
    such other information with regard to its affairs as the Adviser or Board
    of Trustees may reasonably request.

    The Sub-Adviser shall keep the books and records relating to the Assets
    required to be maintained by the Sub-Adviser under this Agreement and shall
    timely furnish to the Adviser all information relating to the Sub-Adviser's
    services under this Agreement needed by the Adviser to keep the other books

    records that it maintains on behalf of the Portfolio are property of the
    Portfolio and the Sub-Adviser will surrender promptly to the Portfolio any
    of such records upon the Portfolio's request; provided, however, that the
    Sub-Adviser may retain a copy of such records.  In addition, for the
    duration of this Agreement, the  Sub-Adviser shall preserve for the periods
    prescribed by Rule  31a-2 under the 1940 Act any such records as are
    required to be maintained by it pursuant to this Agreement, and shall
    transfer said records to any successor sub-adviser upon the termination of

    day with information relating to all transactions concerning the
    Portfolio's Assets and shall provide the Adviser with such information upon

(f) The investment management services provided by the Sub-Adviser under this
    Agreement are not to be deemed exclusive and the Sub-Adviser shall be free
    to render similar services to others, as long as such services do not
    impair the services rendered to the Adviser or the Trust.

(g) The Sub-Adviser shall promptly notify the Adviser of any financial
    condition that is likely to impair the Sub-Adviser's ability to fulfill its
    commitment under this Agreement.

(h) The Sub-Adviser shall review all proxy solicitation materials and be
    responsible for voting and handling all proxies in relation to the
    securities held in the Portfolio.  The Adviser shall instruct the custodian
    and other parties providing services to the Portfolio to promptly forward
    misdirected proxies to the Sub-

    Adviser.

    Services to be furnished by the Sub-Adviser under this Agreement may be
    furnished through the medium of any of the Sub-Adviser's partners, officers
    or employees.

2.  DUTIES OF THE ADVISER.  The Adviser shall continue to have responsibility
    for all services to be provided to the Portfolio pursuant to the Advisory
    Agreement and shall oversee and review the Sub-Adviser's performance of its
    duties under this Agreement; provided, however, that in connection with its
    management of the Assets, nothing herein shall be construed to relieve the
    Sub-Adviser of responsibility for compliance with the Trust's Declaration
    of Trust (as defined herein), the Prospectus, the instructions and
    directions of the Board of Trustees of the Trust, the requirements of the
    1940 Act, the Internal Revenue Code of 1986, and all other applicable
    federal and state laws and regulations, as each is amended from time to
    time.

3.  DELIVERY OF DOCUMENTS.  The Adviser has furnished the Sub-Adviser with
    copies properly certified or authenticated of each of the following
    documents:

(a) The Trust's Agreement and Declaration of Trust, as filed with the Secretary
    of State of the Commonwealth of Massachusetts (such Agreement and
    Declaration of Trust, as in effect on the date of this Agreement and as
    amended from time to time, herein called the "Declaration of Trust");

(b) By-Laws of the Trust (such By-Laws, as in effect on the date of this
    Agreement and as amended from time to time, are herein called the
    "By-Laws");

(c) Prospectus(es) of the Portfolio.

4.  COMPENSATION TO THE SUB-ADVISER.  For the services to be provided by the
    Sub-Adviser pursuant to this Agreement, the Adviser will pay the
    Sub-Adviser, and the Sub-Adviser agrees to accept as full compensation
    therefor, a sub-advisory fee at the rate specified in the Schedule(s) which
    is attached hereto and made part of this Agreement.  The fee will be
    calculated based on the average monthly market value of the Assets under
    the Sub-Adviser s management and will be paid to the Sub-Adviser monthly.
    Except as may otherwise be prohibited by law or regulation (including any
    then current SEC staff interpretation), the Sub-Adviser may, in its
    discretion and from time to time, waive a portion of its fee.

5.  INDEMNIFICATION.  The Sub-Adviser shall indemnify and hold harmless the
    Adviser from and against any and all claims, losses, liabilities or damages
    (including reasonable attorney's fees and other related expenses) howsoever
    arising from or in connection with the performance of the Sub-Adviser s
    obligations under this Agreement; provided, however, that the Sub-Adviser s
    obligation under this Section 5 shall be reduced to the extent that the
    claim against, or the loss, liability or damage experienced by the Adviser,
    is caused by or is otherwise directly related to the Adviser's own willful
    misfeasance, bad faith or negligence, or to the reckless disregard of its
    duties under this Agreement.

    from or in connection with the performance of the Adviser's obligations
    under this Agreement; provided, however, that the Adviser's obligation
    under this Section 5 shall be reduced to the extent that the claim against,
    or the loss, liability or damage experienced by the Sub-Adviser, is caused
    by or is otherwise directly related to the Sub-Adviser's own willful
    misfeasance, bad faith or negligence, or to the reckless disregard of its

6.  DURATION AND TERMINATION.  This Agreement shall become effective upon its
    approval by the Trust's Board of Trustees and by the vote of a majority of
    the outstanding voting securities of the Portfolio; provided, however, that
    at any time the Adviser shall have obtained exemptive relief from the
    Securities and Exchange Commission permitting it to engage a Sub-Adviser
    without first obtaining approval of the Agreement from a majority of the
    outstanding voting securities of the Portfolio(s) involved, the Agreement
    shall become effective upon its approval by the Trust's Board of Trustees.
    Any Sub-Adviser so selected and approved shall be without the protection
    accorded by shareholder approval of an investment adviser's receipt of
    compensation under Section 36(b) of the 1940 Act.

    This Agreement shall continue in effect for a period of more than two years
    from the date hereof only so long as continuance is specifically approved
    at least annually in conformance with the 1940 Act; provided, however, that
    this Agreement may be terminated with respect to the Portfolio (a) by the
    Portfolio at any time, without the payment of any penalty, by the vote of a
    majority of Trustees of the Trust or by the vote of a majority of the
    outstanding voting securities of the Portfolio, (b) by the Adviser at any
    time, without the payment of any penalty, on not more than 60 days' nor
    less than 30 days' written notice to the Sub-Adviser, or (c) by the
    Sub-Adviser at any time, without the payment of any penalty, on 90 days'
    written notice to the Adviser.  This Agreement shall terminate
    automatically and immediately in the event of its assignment, or in the
    event of a termination of the Adviser's agreement with the Trust.  As used
    in this Section 6, the terms "assignment" and "vote of a majority of the
    outstanding voting securities" shall have the respective meanings set forth
    in the 1940 Act and the rules and regulations thereunder, subject to such
    exceptions as may be granted by the SEC under the 1940 Act.

7.  GOVERNING LAW.  This Agreement shall be governed by the internal laws of the
    Commonwealth of Massachusetts, without regard to conflict of law principles;
    provided, however, that nothing herein shall be construed as being
    inconsistent with the 1940 Act.

8.  SEVERABILITY.  Should any part of this Agreement be held invalid by a court
    decision, statute, rule or otherwise, the remainder of this Agreement shall
    not be affected thereby.  This Agreement shall be binding upon and shall
    inure to the benefit of the parties hereto and their respective successors.

    shall be deemed sufficient if delivered or mailed by registered, certified
    or overnight mail, postage prepaid addressed by the party giving notice to

                         SEI INSTITUTIONAL INVESTMENTS TRUST

    AGREEMENT made this 30th day of December, 1996, between SEI Investments
Management Corporation, (the "Adviser") and Lazard London International
Investment Management Limited (the "Sub-Adviser").

    WHEREAS, SEI Institutional Investments Trust, a Massachusetts business
trust (the "Trust"), is registered as an open-end management investment company
under the Investment Company Act of 1940, as amended (the "1940  Act"); and

    WHEREAS, the Adviser has entered into an Investment Advisory Agreement
dated June 14, 1996 (the "Advisory Agreement") with the Trust, pursuant to which
the Adviser will act as investment adviser to the International Equity Portfolio
(the "Portfolio"), which is a series of the Trust; and

    WHEREAS, the Adviser, with the approval of the Trust, desires to retain the
Sub-Adviser to provide investment advisory services to the Adviser in connection
with the management of the Portfolio, and the Sub-Adviser is willing to render
such investment advisory services.

    NOW, THEREFORE, the parties hereto agree as follows:

1.  DUTIES OF THE SUB-ADVISER.  Subject to supervision by the Adviser and the
    Trust's Board of Trustees, the Sub-Adviser shall manage all of the
    securities and other assets of the Portfolio entrusted to it hereunder (the
    "Assets"), including the purchase, retention and disposition of the Assets,
    in accordance with the Portfolio's investment objectives, policies and
    restrictions as stated in the Portfolio's prospectus and statement of
    additional information,  as currently in effect and as amended or
    supplemented from time to time (referred to collectively as the
    "Prospectus"), and subject to the following:

(a) The Sub-Adviser shall, in consultation with and subject to the direction of
    the Adviser, determine from time to time what Assets will be purchased,
    retained or sold by the Portfolio, and what portion of the Assets will be
    invested or held uninvested in cash.

(b) In the performance of its duties and obligations under this Agreement, the
    Sub-Adviser shall act in conformity with the Trust's Declaration of Trust
    (as defined herein) and the Prospectus and with the instructions and
    directions of the Adviser and of the Board of Trustees of the Trust and
    will conform to and comply with the requirements of the 1940 Act, the
    Internal Revenue Code of 1986, and all other applicable federal and state
    laws and regulations, as each is amended from time to time.

(c) The Sub-Adviser shall determine the Assets to be purchased or sold by the
    Portfolio as provided in subparagraph (a) and will place orders with or
    through such persons, brokers or dealers to carry out the policy with
    respect to brokerage set forth in the Portfolio's Registration Statement
    (as defined herein) and Prospectus or as the Board of Trustees or the
    Adviser may direct from time to time, in conformity with federal securities
    laws.  In executing Portfolio transactions and selecting brokers or
    dealers, the Sub-Adviser will use its best efforts to seek on behalf of the
    Portfolio the best overall terms available.  In assessing the best overall
    terms available for any transaction, the Sub-Adviser shall consider all
    factors that it deems relevant, including the breadth of the market in the
    security, the price of the security, the financial condition and execution
    capability of the broker or dealer, and the reasonableness of the
    commission, if any, both for the specific transaction and on a continuing
    basis.  In evaluating the best overall terms available, and in selecting
    the broker-dealer to execute a particular transaction, the Sub-Adviser may
    also consider the brokerage and research services provided (as those terms
    are defined in

<PAGE>

    Section 28(e) of the Securities Exchange Act of 1934).  Consistent with any
    guidelines established by the Board of Trustees of the Trust, the
    Sub-Adviser is authorized to pay to a broker or dealer who provides such
    brokerage and research services a commission for executing a portfolio
    transaction for the Portfolio which is in excess of the amount of
    commission another broker or dealer would have charged for effecting that
    transaction if, but only if, the Sub-Adviser determines in good faith that
    such commission was reasonable in relation to the value of the brokerage
    and research services provided by such broker or dealer - - viewed in terms
    of that particular transaction or terms of the overall responsibilities of
    the Sub-Adviser to the Portfolio.  In addition, the Sub-Adviser is
    authorized to allocate purchase and sale orders for securities to brokers
    or dealers (including brokers and dealers that are affiliated with the
    Adviser, Sub-Adviser or the Trust's principal underwriter) to take into
    account the sale of shares of the Trust if the Sub-Adviser believes that
    the quality of the transaction and the commission are comparable to what
    they would be with other qualified firms.  In no instance, however, will
    the Portfolio's Assets be purchased from or sold to the Adviser,
    Sub-Adviser, the Trust's principal underwriter, or any affiliated person of
    either the Trust, Adviser, the Sub-Adviser or the principal underwriter,
    acting as principal in the transaction, except to the extent permitted by
    the Securities and Exchange Commission ("SEC") and the 1940 Act.

(d) The Sub-Adviser shall maintain all books and records with respect to
    transactions involving the Assets required by subparagraphs (b)(5), (6),
    (7), (9), (10) and (11) and paragraph (f) of Rule 31a-1 under the 1940 Act.
    The Sub-Adviser shall provide to the Adviser or the Board of Trustees such
    periodic and special reports, balance sheets or financial information, and
    such other information with regard to its affairs as the Adviser or Board
    of Trustees may reasonably request.

    The Sub-Adviser shall keep the books and records relating to the Assets
    required to be maintained by the Sub-Adviser under this Agreement and shall
    timely furnish to the Adviser all information relating to the Sub-Adviser's
    services under this Agreement needed by the Adviser to keep the other books
    and records of the Portfolio required by Rule 31a-1 under the 1940 Act.
    The Sub-Adviser shall also furnish to the Adviser any other information
    relating to the Assets that is required to be filed by the Adviser or the
    Trust with the SEC or sent to shareholders under the 1940 Act (including
    the rules adopted thereunder) or any exemptive or other relief that the
    Adviser or the Trust obtains from the SEC.  The Sub-Adviser agrees that all
    records that it maintains on behalf of the Portfolio are property of the
    Portfolio and the Sub-Adviser will surrender promptly to the Portfolio any
    of such records upon the Portfolio's request; provided, however, that the
    Sub-Adviser may retain a copy of such records.  In addition, for the
    duration of this Agreement, the  Sub-Adviser shall preserve for the periods
    prescribed by Rule  31a-2 under the 1940 Act any such records as are
    required to be maintained by it pursuant to this Agreement, and shall
    transfer said records to any successor sub-adviser upon the termination of
    this Agreement (or, if there is no successor sub-adviser, to the Adviser).

(e) The Sub-Adviser shall provide the Portfolio's custodian on each business
    day with information relating to all transactions concerning the
    Portfolio's Assets and shall provide the Adviser with such information upon
    request of the Adviser.

(f) The investment management services provided by the Sub-Adviser under this
    Agreement are not to be deemed exclusive and the Sub-Adviser shall be free
    to render similar services to others, as long as such services do not
    impair the services rendered to the Adviser or the Trust.

(g) The Sub-Adviser shall promptly notify the Adviser of any financial
    condition that is likely to impair the Sub-Adviser's ability to fulfill its
    commitment under this Agreement.

(h) The Sub-Adviser shall have discretion over voting and handling all proxies
    in relation to the securities


                                          2
<PAGE>

    held in the Portfolio including, without limitation, whether or not to
    vote.  The Adviser shall instruct the custodian and other parties providing
    services to the Portfolio to promptly forward misdirected proxies to the
    Sub-Adviser.

    Services to be furnished by the Sub-Adviser under this Agreement may be
    furnished through the medium of any of the Sub-Adviser's partners, officers
    or employees.

2.  DUTIES OF THE ADVISER.  The Adviser shall continue to have responsibility
    for all services to be provided to the Portfolio pursuant to the Advisory
    Agreement and shall oversee and review the Sub-Adviser's performance of its
    duties under this Agreement; provided, however, that in connection with its
    management of the Assets, nothing herein shall be construed to relieve the
    Sub-Adviser of responsibility for compliance with the Trust's Declaration
    of Trust (as defined herein), the Prospectus, the instructions and
    directions of the Board of Trustees of the Trust, the requirements of the
    1940 Act, the Internal Revenue Code of 1986, and all other applicable
    federal and state laws and regulations, as each is amended from time to
    time.

3.  DELIVERY OF DOCUMENTS.  The Adviser has furnished the Sub-Adviser with
    copies properly certified or authenticated of each of the following
    documents:

(a) The Trust's Agreement and Declaration of Trust, as filed with the Secretary
    of State of the Commonwealth of Massachusetts (such Agreement and
    Declaration of Trust, as in effect on the date of this Agreement and as
    amended from time to time, herein called the "Declaration of Trust");

(b) By-Laws of the Trust (such By-Laws, as in effect on the date of this
    Agreement and as amended from time to time, are herein called the
    "By-Laws");

(c) Prospectus(es) of the Portfolio.

(d) The Adviser will promptly furnish to the Sub-Adviser any and all amendments
    or other changes to the documents specified in this Section 3, and the
    Sub-Adviser shall not be charged with complying with any such document or
    amendment not so delivered to the Sub-Adviser, unless the Sub-Adviser
    reasonably should have known the terms of such document or amendment.

4.  COMPENSATION TO THE SUB-ADVISER.  For the services to be provided by the
    Sub-Adviser pursuant to this Agreement, the Adviser will pay the
    Sub-Adviser, and the Sub-Adviser agrees to accept as full compensation
    therefor, a sub-advisory fee at the rate specified in the Schedule(s) which
    is attached hereto and made part of this Agreement.  The fee will be
    calculated at the end of each month based on the average of the market
    value of the Assets under the Sub-Adviser s management at the end of the
    preceding month and at the end of the current month, and will be paid to
    the Sub-Adviser monthly.  The fee hereunder shall initially be calculated
    for the period beginning [MONTH DATE, 1997].  Except as may otherwise be
    prohibited by law or regulation (including any then current SEC staff
    interpretation), the Sub-Adviser may, in its discretion and from time to
    time, waive a portion of its fee.

5.  INDEMNIFICATION.  The Sub-Adviser shall indemnify and hold harmless the
    Adviser from and against any and all claims, losses, liabilities or damages
    (including reasonable attorney's fees and other related expenses) howsoever
    arising from or in connection with the performance of the Sub-Adviser s
    obligations under this Agreement; provided, however, that the Sub-Adviser s
    obligation under this Section 5 shall be reduced to the extent that the
    claim against, or the loss, liability or damage experienced by the Adviser,
    is caused by or is otherwise related to the Adviser's own willful
    misfeasance, bad faith or negligence, or to the reckless disregard of its
    duties under this Agreement.

                                DISTRIBUTION AGREEMENT
                         SEI INSTITUTIONAL INVESTMENTS TRUST

    THIS AGREEMENT is made as of this 14th day of June, 1996 between SEI
Institutional Investments Trust (the "Trust"), a Massachusetts business trust,
and SEI Financial Services Company (the "Distributor"), a Pennsylvania
corporation.

    WHEREAS, the Trust is registered as an investment company with the
Securities and Exchange Commission (the "SEC") under the Investment Company Act
of 1940, as amended (the "1940 Act"), and its shares are registered with the SEC
under the Securities Act of 1933, as amended (the "1933 Act"); and

    WHEREAS, the Distributor is registered as a broker-dealer with the SEC
under the Securities Exchange Act of 1934, as amended;

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

    ARTICLE 1. SALE OF SHARES. The Trust grants to the Distributor the
exclusive right to sell shares (the "Shares") of the portfolios (the
"Portfolios") of the Trust at the net asset value per Share, plus any applicable
sales charge in accordance with the Trust's current prospectuses, as agent and
on behalf of the Trust, during the term of this Agreement and subject to the
registration requirements of the 1933 Act, the rules and regulations of the SEC
and the laws governing the sale of securities in the various states (the "Blue
Sky Laws").

    ARTICLE 2. 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, in connection with the distribution of the
Shares of the Trust; provided, however, that the Distributor shall not be
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 when it determines
it would be uneconomical for it to do so or to maintain its registration in any
jurisdiction in which it is now registered nor obligate the Distributor to sell
any particular number of Shares.

    ARTICLE 3. COMPENSATION. As compensation for providing the services under
this Agreement:

    (a)  The Distributor shall receive from the Trust:

         (1) all distribution and service fees, as applicable, at the rate and
         under the terms and conditions set forth in each Distribution and
         Service Plan adopted by the appropriate class of Shares of each of the
         Portfolios, as such Plans may be amended from time to time, and
         subject to any further limitations on such fees as the Board of
         Directors of the Trust may impose;

         (2) all contingent deferred sales charges ("CDSC") applied on
         redemptions of CDSC Class Shares, as applicable, of each Portfolio on
         the terms and subject to such waivers as are described in the Trust's
         Registration Statement and current prospectuses, as amended from time
         to time, or as otherwise required pursuant to applicable law; and

         (3) all front-end sales charges, as applicable, on purchases of
         front-end load Shares of each Portfolio sold subject to such charges
         as described in the Trust's Registration Statement and


<PAGE>


         current prospectuses, as amended from time to time. The Distributor,
         or brokers, dealers and other financial institutions and
         intermediaries that have entered into sub-distribution agreements with
         the Distributor, may collect the gross proceeds derived from the sale
         of such front-end load Shares, remit the net asset value thereof to
         the Trust upon receipt of the proceeds and retain the applicable sales
         charge.

    (b)  The Distributor may reallow any or all of the distribution or service 
         fees, CDSC, and front-end sales charges which it is paid by the Trust 
         to such brokers, dealers and other financial institutions and 
         intermediaries as the Distributor may from time to time determine.

    (c)  The Distributor may transfer its right to the payments described in
    this Article 3 to third persons who provide Trusting to the Distributor,
    provided that any such transfer shall not be deemed a transfer of the
    Distributor's obligations under this Agreement. Upon receipt of direction
    from the Distributor to pay such fees to a transferee, the Trust shall make
    payment in accordance with such direction.

    ARTICLE 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 current registration statements and prospectuses of the
Trust filed with the SEC or contained in Shareholder 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 that such literature and materials have been
prepared in accordance with applicable rules and regulations.

    ARTICLE 5. REGISTRATION OF SHARES. The Trust agrees that it will take all
action necessary to register Shares under the federal and state securities laws
so that there will be available for sale the number of Shares the Distributor
may reasonably be expected to sell and to pay all fees associated with said
registration. The Trust shall make available to the Distributor such number of
copies of its currently effective prospectuses and statement of additional
information 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 Shares of the Trust.

    ARTICLE 6. INDEMNIFICATION OF DISTRIBUTOR. 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 1933 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 and
disbursements incurred in connection therewith), arising by reason of any person
acquiring any Shares, based upon the ground that the registration statement,
prospectus, Shareholder 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 made not misleading. However, the Trust does not
agree to indemnify the Distributor or hold it harmless to the extent that the
statements 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 to be deemed to protect the
Distributor against any liability to the Trust or its Shareholders to which the
Distributor or such person otherwise would be subject by reason of willful
misfeasance, bad faith or 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 Trust to be liable to the Distributor under the


                                          2
<PAGE>


indemnity agreement contained in this paragraph with respect to any claim made
against the Distributor or any person indemnified unless the Distributor or
other 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 such other 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 subject to this indemnity provision. If the Trust elects to 
assume the defense of any such claim, the defense shall be conducted by counsel
chosen by the Trust and satisfactory to the indemnified defendants in the suit
whose approval shall not be unreasonably withheld. In the event that the Trust
elects to assume the defense of any suit and retain counsel, the indemnified
defendants shall bear the fees and expenses of any additional counsel retained
by them. If the Trust does not elect to assume the defense of a suit, it will
reimburse the indemnified defendants for the reasonable fees and expenses of any
counsel retained by the indemnified defendants.

    The Trust agrees to notify the Distributor promptly of the commencement of
any litigation or proceedings against it or any of its officers or Directors in
connection with the issuance or sale of any of its Shares. 

    ARTICLE 7. INDEMNIFICATION OF TRUST. The Distributor covenants and agrees
that it will indemnify and hold harmless the Trust and each of its Directors 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) based upon the 1933 Act or any other statute or common law
and arising by reason of any person acquiring any Shares, and alleging a
wrongful act of the Distributor or any of its employees or alleging that the
registration statement, prospectus, Shareholder 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 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 other person indemnified to be deemed to protect the Trust or any other
person against any liability to which the Trust or such other person would
otherwise be subject by reason of willful misfeasance, bad faith or 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 upon 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.


                                          3
<PAGE>


    The Distributor 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 the claim, but if the Distributor elects to assume the defense, the
defense shall be conducted by counsel chosen by the Distributor and satisfactory
to the indemnified defendants whose approval shall not be unreasonably withheld.
In the event that the Distributor elects to assume the defense of any suit and
retain counsel, the 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 indemnified 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 the issue and sale
of any of the Trust's Shares.

    ARTICLE 8. EFFECTIVE DATE. This Agreement shall be effective upon its
execution, and unless terminated as provided, shall continue in force for one
year from the effective date and thereafter year to year, provided that such
annual continuance is approved by (i) either the vote of a majority of the
Directors of the Trust, or the vote of a majority of the outstanding voting
securities of the Trust, and (ii) the vote of a majority of those Directors of
the Trust who are not parties to this Agreement or the Trust's Distribution Plan
or interested persons of any such party ("Qualified Directors"), cast 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 1940 Act. In addition, this Agreement may at any time be
terminated without penalty by the Distributor, by a vote of a majority of
Qualified Directors or by vote of a majority of the outstanding voting
securities of the Trust upon not less than sixty days prior written notice to
the other party.

    ARTICLE 9. 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 680 East Swedesford Road, Wayne, Pennsylvania, and if to the
Distributor, at 680 East Swedesford Road, Wayne, Pennsylvania 19087.

    ARTICLE 10. LIMITATION OF LIABILITY. A copy of the Articles of
Incorporation of the Trust is on file with the Secretary of State of Maryland,
and notice is hereby given that this Agreement is executed on behalf of the
Directors of the Trust as Directors and not individually and that the
obligations of this instrument are not binding upon any of the Directors,
officers or shareholders of the Trust individually but binding only upon the
assets and property of the Trust.

    ARTICLE 11. GOVERNING LAW. This Agreement shall be construed in accordance
with the laws of the state of Maryland and the applicable provisions of the 1940
Act. To the extent that the applicable laws of the state of Maryland, or any of
the provisions herein, conflict with the applicable provisions of the 1940 Act,
the latter shall control.

    ARTICLE 12. MULTIPLE ORIGINALS. 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.


                                          4

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

                                 CUSTODIAN AGREEMENT
                         SEI INSTITUTIONAL INVESTMENTS TRUST

    This Agreement, dated as of the 17th day of June, 1996 by and between SEI
INSTITUTIONAL INVESTMENTS TRUST (the "Trust"), a business trust duly organized
under the laws of the Commonwealth of Massachusetts and CORESTATES BANK, N.A.
(the "Bank").

                                     WITNESSETH:

    WHEREAS, the Trust desires to appoint the Bank to act as Custodian of its
portfolio securities, cash and other property from time to time deposited with
or collected by the Bank for the Trust;

    WHEREAS, the Bank is qualified and authorized to act as Custodian for the
Trust and the separate series thereof (each a "Fund" and, collectively, the
"Funds"), and is willing to act in such capacity upon the terms and conditions
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:

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

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

DEPOSITORY: The term Depository means any depository service which acts as a
system for the central handling of securities where all securities of any
particular class or series of an issuer deposited within the system are treated
as fungible and may be transferred by bookkeeping entry without physical
delivery.

PROPER INSTRUCTIONS. For purposes of this Agreement, the Custodian shall be
deemed to have received Proper Instructions upon receipt of written (including
instructions received by means of computer terminals or facsimile
transmissions), telephone or telegraphic instructions from a person or persons
authorized from time to time by the Trustees of the Trust to give the particular
class of instructions. Telephone or telegraphic instructions shall be confirmed
in writing by such person or persons as said Trustees 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 the Trust's
failure to confirm such instructions in writing.


                                        - 1 -
<PAGE>

SECURITIES: The term Securities means stocks, bonds, rights, warrants and all
other negotiable or non-negotiable paper issued in certificated or book-entry
form commonly known as "securities" in banking custom or practice.

SHAREHOLDERS: The term Shareholders shall mean the registered owners from time
to time of the Shares of the Trust in accordance with the registry records
maintained by the Trust or agents on its behalf.

SHARES: The term Shares of the Trust shall mean the units of beneficial
interest.

2. The Trust hereby appoints the Custodian as Custodian of the Trust's cash,
Securities and other property, to be held by the Custodian as provided in this
Agreement. The Custodian hereby accepts such appointment subject to the terms
and conditions hereinafter provided. The Bank shall open a separate custodial
account in the name of the Trust on the books and records of the Bank to hold
the Securities of the Trust deposited with, transferred to or collected by the
Bank for the account of the Trust, and a separate cash account to which the Bank
shall credit monies received by the Bank for the account of or from the Trust.
Such cash shall be segregated from the assets of others and shall be and remain
the sole property of the Trust.

3. The Trust 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 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 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 Trust.

4. The Trust will cause to be deposited with the Custodian hereunder 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.

5. The Bank, acting as agent for the Trust, is authorized, directed and
instructed subject to the further provisions of this Agreement:

    (a)  to hold Securities issued only in bearer form in bearer form;

    (b)  to register in the name of the nominee of the Bank, the Bank's
         Depositories, or sub-custodians, (i) Securities issued only in
         registered form, and (ii) Securities issued in both bearer and
         registered form, which are freely interchangeable without penalty;


                                        - 2 -

    (c)  to deposit any Securities which are eligible for deposit (i) with any
         domestic or foreign Depository on such terms and conditions as such
         Depository may require, including provisions for limitation or
         exclusion of liability on the part of the Depository; and (ii) with
         any sub-custodian which the Bank uses, including any subsidiary or
         affiliate of the Bank;

    (d)  (i)     to credit for the account of the Trust all proceeds received
                 and payable on or in respect of the assets maintained
                 hereunder,

         (ii)    to debit the account of the Trust for the cost of acquiring
                 Securities the Bank has received for the Trust, against
                 delivery of such Securities to the Bank,

         (iii)   to present for payment Securities and other obligations
                 (including coupons) upon maturity, when called for
                 redemption, and when income payments are due, and

         (iv)    to make exchanges of Securities which, in the Bank's
                 opinion, are purely ministerial as, for example, the
                 exchange of Securities in temporary form for Securities in
                 definitive form or the mandatory exchange of certificates;

    (e)  to forward to the Trust, and/or any other person designated by the
         Trust, all proxies and proxy materials received by the Bank in
         connection with Securities held in the Trust's account, which have
         been registered in the name of the Bank's nominee, or are being held
         by any Depository, or sub-custodian, on behalf of the Bank;

    (f)  to sell any fractional interest of any Securities which the Bank has
         received resulting from any stock dividend, stock split, distribution,
         exchange, conversion or similar activity;

    (g)  to release the Trust's name, address and aggregate share position to
         the issuers of any domestic Securities in the account of the Trust,
         provided, however, the Trust may instruct the Bank not to provide any
         such information to any issuer;

    (h)  to endorse and collect all checks, drafts or other orders for the
         payment of money received by the Bank for the account of or from the
         Trust;

         automatic reinvestment of all income and capital gains distributions
         on those Securities in new shares (an "Automatic Reinvestment
         Program"), or instruct any Depository holding such Securities to    
         enroll those Securities in an Automatic Reinvestment Program;


                                        - 3 -
<PAGE>

    (j)  at the direction of the Trust, to receive, deliver and transfer
         Securities and make payments and collections of monies in connection
         therewith, enter purchase and sale orders and perform any other acts
         incidental or necessary to the performance of the above acts with
         brokers, dealers or similar agents selected by the Trust, including
         any broker, dealer or similar agent affiliated with the Bank, for the
         account and risk of the Trust in accordance with accepted industry
         practice in the relevant market, provided, however, if it is
         determined that any certificated Securities transferred to a
         Depository or sub-custodian, the Bank, or the Bank's nominee, the
         Bank's sole responsibility for such Securities under this Agreement
         shall be to safekeep the Securities in accordance with Section 11
         hereof; and

    (k)  to notify the Trust and/or any other person designated by the Trust
         upon receipt of notice by the Bank of any call for redemption, tender
         offer, subscription rights, merger, consolidation, reorganization or
         recapitalization which (i) appears in The Wall Street Journal (New
         York edition), The Standard & Poor's Called Bond Record for Preferred
         Stocks, Financial Daily Called Bond Service, The Kenny Services, any
         official notifications from The Depository Trust Company and such
         other publications or services to which the Bank may from time to time
         subscribe, (ii) requires the Bank to act in response thereto, and
         (iii) pertain to Securities belonging to the Trust and held hereunder
         which have been registered in the name of the Bank's nominee or are
         being held by a Depository or sub-custodian on behalf of the Bank.
         Notwithstanding anything contained herein to the contrary, the Trust
         shall have the sole responsibility for monitoring the applicable dates
         on which Securities with put option features must be exercised. All
         solicitation fees payable to the Bank as agent in connection herewith
         will be retained by the Bank unless expressly agreed to the contrary
         in writing by the Bank. 

Notwithstanding anything in this Section to the contrary, the Bank is authorized
to hold Securities for the Trust which have transfer limitations imposed upon
them by the Securities Act of 1933, as amended, or represent shares of mutual
funds (i) in the name of the Trust, (ii) in the name of the Bank's nominee, or
(iii) with any Depository or sub-custodian.

6. 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 Trust and the Custodian. The Bank is authorized to charge the Trust's
account for such compensation. All expenses and taxes payable with respect to
the Securities in the account of the Trust including, without limitation,
commission charges on purchases and sales and the amount of any loss or
liability for stockholders' assessments or otherwise, claimed or asserted
against the bank or against the Bank's nominee by reason of any registration
hereunder shall be charged to the Trust.

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

    (a)  render to the Trust a daily report of all monies received or paid on
         behalf of the Trust; and


                                        - 4 -
<PAGE>

    (b)  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 Trust with respect to said Custodian's activities
         in accordance with 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
         Trust and in the event of termination of this Agreement will be
         relinquished to the Trust.

8. Any Securities deposited with any Depository or with any sub-custodian will
be represented in accounts in the name of the Bank which include only property
held by the Bank as Custodian for customers in which the Bank acts in a
fiduciary or agency capacity.

Should any Securities which are forwarded to the Bank by the Trust, and which
are subsequently deposited to the Bank's account in any Depository or with any
sub-custodian, or which the Trust may arrange to deposit in the Bank's account
in any Depository or with any sub-custodian, not be deemed acceptable for
deposit by such Depository or sub-custodian, for any reason, and as a result
thereof there is a short position in the account of the Bank with the Depository
for such Security, the Trust agrees to furnish the Bank immediately with like
Securities in acceptable form.

9. The Trust represents and warrants that: (i) it has the legal right, power and
authority to execute, deliver and perform this Agreement and to carry out all of
the transactions contemplated hereby; (ii) it has obtained all necessary
authorizations; (iii) the execution, delivery and performance of this Agreement
and the carrying out of any of the transactions contemplated hereby will not be
in conflict with, result in a breach of or constitute a default under any
agreement or other instrument to which the Trust is a party or which is
otherwise known to the Trust; (iv) it does not require the consent or approval
of any governmental agency or instrumentality, except any such consents and
approvals which the Trust has obtained; (v) the execution and delivery of this
Agreement by the Trust will not violate any law, regulation, charter, by-law,
order of any court or governmental agency or judgment applicable to the Trust;
and (vi) all persons executing this Agreement on behalf of the Trust and
carrying out the transactions contemplated hereby on behalf of the Trust are
duly authorized to do so.

In the event any of the foregoing representations should become untrue,
incorrect or misleading, the Trust agrees to notify the Bank immediately in
writing thereof.

10. The Bank represents and warrants that: (i) it has the legal right, power and
authority to execute, deliver and perform this Agreement and to carry out all of
the transactions contemplated hereby; (ii) it has obtained all necessary
authorizations; (iii) the execution, delivery and performance of this Agreement
and the carrying out of any of the transactions contemplated hereby will not be
in conflict with, result in a breach of or constitute a default under any
agreement or other instrument to which the Bank is a party or which is otherwise
known to the Bank; (iv) it does not require the consent or approval of any
governmental agency or instrumentality, except any such consents and approvals
which the Bank has obtained; (v) the


                                        - 5 -
<PAGE>

execution and delivery of this Agreement by the Bank will not violate any law,
regulation, charter, by-law, order of any court or governmental agency or
judgment applicable to the Bank; and (vi) all persons executing this Agreement
on behalf of the Bank and carrying out the transactions contemplated hereby on
behalf of the Bank are duly authorized to do so. In the event that any of the
foregoing representations should become untrue, incorrect or misleading, the
Bank agrees to notify the Trust immediately in writing thereof.

11. All cash and Securities held by the Bank hereunder shall be kept with the
care exercised as to the Bank's own similar property. The Bank may at its option
insure itself against loss from any cause but shall be under no obligation to
insure for the benefit of the Trust.

12. No liability of any kind shall be attached to or incurred by the Custodian
by reason of its custody of the Trust's assets 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 Custodian
Agreement. Without limiting the generality of the foregoing sentence, the
Custodian:

    (a)  may rely upon the advice of counsel for the Trust; 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 Trust or its authorized officers or
         agents;

    (c)  is authorized to accept a certificate of the Secretary or Assistant
         Secretary of the Trust, 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; and

    (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, Trust or other proper
         party or parties.

13. The Trust, its successors and assigns do hereby fully indemnify and hold
harmless the 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 Trust 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
units of


                                        - 6 -
<PAGE>

beneficial interest in the Trust, or from the failure of the Trust to perform
any duty or obligation under this Agreement.

Upon written request of the Custodian, the Trust 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.

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

15. Either the Trust 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 Trust or by the Custodian, the
Trustees of the Trust shall, by resolution duly adopted, promptly appoint a
successor Custodian (the "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 cash and Securities of a mutual fund.
Upon receipt of written notice from the Trust of the appointment of such
Successor Custodian and upon receipt of Proper Instructions, the Custodian shall
deliver such cash and Securities as it may then be holding hereunder directly
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
Trust 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.

Subject to the provisions of Section 21 hereof, 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, PROVIDED, HOWEVER, in every case that said Successor corporation maintains
the qualifications set out in Section 17(f) of the Investment Company Act of
1940, as amended.

16. This Agreement shall take effect when assets of the Trust are first
delivered to the Custodian.

17. 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.


                                        - 7 -

18. A copy of the Declaration of Trust of the Trust is on file with the
Secretary of State 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 not individually and that the obligations of this instrument 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. No
Fund of the Trust shall be liable for the obligations of any other Fund of the
Trust.

19. 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 Trust under the Investment Company Act of 1940, as amended,
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 Trust.

Subject to security requirements of the Custodian applicable to its own
employees having access to similar records within the Custodian, the books and
records of the Custodian pertaining to this Agreement shall be open to
inspection and audit at any reasonable times by officers of, attorneys for, and
auditors employed by, the Trust.

20. 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.

21. 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 Trust without the written consent of
the Custodian, or by the Custodian without the written consent of the Trust,
authorized or approved by a resolution of its Board of Trustees.

22. All communications (other than Proper Instructions which are to be furnished
hereunder to either party, or under any amendment hereto, shall be sent by mail
to the address listed below, provided that in the event that the Bank, in its
sole discretion, shall determine that an emergency exists, the Bank may use such
other means of communications as the Bank deems advisable.

                                  CUSTODIAN CONTRACT

      This Contract between SEI Institutional Investments Trust, a business
trust organized and existing under the laws of Massachusetts, having its
principal place of business at 680 East Swedesford Road, Wayne, Pennsylvania
hereinafter called the "Fund", and State Street Bank and Trust Company, a
Massachusetts trust company, having its principal place of business at 225
Franklin Street, Boston, Massachusetts, 02110, hereinafter called the
"Custodian",

                                     WITNESSETH:

      WHEREAS, the Fund is authorized to issue shares in separate series, with
each such series representing interests in a separate portfolio of securities
and other assets; and

      WHEREAS, the Fund intends to initially offer shares in three series, the
International Fixed Income Fund, Emerging Markets Equity Fund and International
Equity Fund (such series together with all other series subsequently established
by the Fund and made subject to this Contract in accordance with paragraph 17,
being herein referred to as the "Portfolio(s)");

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

1.    EMPLOYMENT OF CUSTODIAN AND PROPERTY TO BE HELD BY IT

      The Fund hereby employs the Custodian as the custodian of the assets of
the Portfolios of the Fund, including securities which the Fund, on behalf of
the applicable Portfolio desires to be held in places within the United States
("domestic securities") and securities it desires to be held outside the United
States ("foreign securities") pursuant to the provisions of the Declaration of
Trust. The Fund on behalf of the Portfolio(s) agrees to deliver to the Custodian
all securities and cash of the Portfolios, and all payments of income, payments
of principal or capital distributions received by it with respect to all
securities owned by the Portfolio(s) from time to time, and the cash
consideration received by it for such new or treasury shares of beneficial
interest of the Fund representing interests in the Portfolios, ("Shares") as may
be issued or sold from time to time. The Custodian shall not be responsible for
any property of a Portfolio held or received by the Portfolio and not delivered
to the Custodian.

      Upon receipt of "Proper Instructions" (within the meaning of Article 5),
the Custodian shall on behalf of the applicable Portfolio(s) from time to time
employ one or more sub-custodians, located in the United States but only in
accordance with an applicable vote by the Board of Trustees of the Fund on
behalf of the applicable Portfolio(s), and provided that the Custodian shall

      Custodian in the Banking Department of the Custodian or in such other
      banks or trust companies as it may in its discretion deem necessary or
      desirable; PROVIDED, however, that 


                                          4
<PAGE>

      every such bank or trust company shall be qualified to act as a custodian
      under the Investment Company Act of 1940 and that each such bank or trust
      company and the funds to be deposited with each such bank or trust
      company shall on behalf of each applicable Portfolio be approved by vote
      of a majority of the Board of Trustees of the Fund. Such funds shall be
      deposited by the Custodian in its capacity as Custodian and shall be
      withdrawable by the Custodian only in that capacity.

2.5   AVAILABILITY OF FEDERAL FUNDS. Upon mutual agreement between the Fund on
      behalf of each applicable Portfolio and the Custodian, the Custodian

      each Portfolio shall be entitled either by law or pursuant to custom in
      the securities business, and shall collect on a timely basis all income
      and other payments with respect to bearer domestic securities if, on the
      date of payment by the issuer, such securities are held by the Custodian
      or its agent thereof and shall credit such income, as collected, to such
      Portfolio's custodian account. Without limiting the generality of the
      foregoing, the Custodian shall detach and present for payment all coupons
      and other income items requiring presentation as and when they become due
      and shall collect interest when due on securities held hereunder. Income
      due each Portfolio on securities loaned pursuant to the provisions of
      Section 2.2 (10) shall be the responsibility of the Fund. The Custodian
      will have no duty or responsibility in connection therewith, other than

            Proper Instructions from the Fund as defined in Article 5;

3.    DUTIES OF THE CUSTODIAN WITH RESPECT TO PROPERTY OF THE FUND HELD OUTSIDE
      OF THE UNITED STATES
      
3.1   APPOINTMENT OF FOREIGN SUB-CUSTODIANS. The Fund hereby authorizes and
      instructs the Custodian to employ as sub-custodians for the Portfolio's
      securities and other assets maintained outside the United States the
      foreign banking institutions and foreign securities depositories
      designated on Schedule A hereto ("foreign sub-custodians"). Upon receipt
      of "Proper Instructions", as defined in Section 5 of this Contract,
      together with a certified resolution of the Fund's Board of Trustees, the
      Custodian and the Fund may agree to amend Schedule A hereto from time to
      time to designate additional foreign banking institutions and foreign
      securities depositories to act as sub-custodian. Upon receipt of Proper
      Instructions, the Fund may instruct the Custodian to cease the employment
      of any one or more such sub-custodians for maintaining custody of the
      Portfolio's assets. 

3.2   ASSETS TO BE HELD. The Custodian shall limit the securities and other
      assets maintained in the custody of the foreign sub-custodians to: (a)
      "foreign securities", as defined in paragraph (c)(1) of Rule 17f-5 under
      the Investment Company Act of 1940, and (b) cash and cash equivalents in
      such amounts as the Custodian or the Fund may determine to be reasonably
      necessary to effect the Portfolio's foreign securities transactions. The
      Custodian shall identify on its books as belonging to the Fund, the
      foreign securities of the Fund held by each foreign sub-custodian. 


                                          10
<PAGE>

3.3   FOREIGN SECURITIES SYSTEMS. Except as may otherwise be agreed upon in
      writing by the Custodian and the Fund, assets of the Portfolios shall be
      maintained in a clearing agency which acts as a securities depository or
      in a book-entry system for the central handling of securities located
      outside the United States (each a "Foreign Securities System") only
      through arrangements implemented by the foreign banking institutions
      serving as sub-custodians pursuant to the terms hereof (Foreign
      Securities Systems and U.S. Securities Systems are collectively referred
      to herein as the "Securities Systems"). Where possible, such arrangements
      shall include entry into agreements containing the provisions set forth
      in Section 3.5 hereof.

3.4   HOLDING SECURITIES. The Custodian may hold securities and other non-cash
      property for all of its customers, including the Fund, with a foreign
      sub-custodian in a single account that is identified as belonging to the
      Custodian for the benefit of its customers, PROVIDED HOWEVER, that (i)
      the records of the Custodian with respect to securities and other
      non-cash property of the Fund which are maintained in such account shall
      identify by book-entry those securities and other non-cash property
      belonging to the Fund and (ii) the Custodian shall require that
      securities and other non-cash property so held by the foreign
      sub-custodian be held separately from any assets of the foreign
      sub-custodian or of others. 

3.5   AGREEMENTS WITH FOREIGN BANKING INSTITUTIONS. Each agreement with a
      foreign banking institution shall provide that: (a) the assets of each
      Portfolio will not be subject to any right, charge, security interest,
      lien or claim of any kind in favor of the foreign banking institution or
      its creditors or agent, except a claim of payment for their safe custody
      or administration; (b) beneficial ownership for the assets of each
      Portfolio will be freely transferable without the payment of money or
      value other than for custody or administration; (c) adequate records will
      be maintained identifying the assets as belonging to each applicable
      Portfolio; (d) officers of or auditors employed by, or other
      representatives of the Custodian, including to the extent permitted under
      applicable law the independent public accountants for the Fund, will be
      given access to the books and records of the foreign banking institution
      relating to its actions under its agreement with the Custodian; and (e)
      assets of the Portfolios held by the foreign sub-custodian will be
      subject only to the instructions of the Custodian or its agents.

3.6   ACCESS OF INDEPENDENT ACCOUNTANTS OF THE FUND. Upon request of the Fund,
      the Custodian will use its best efforts to arrange for the independent
      accountants of the Fund to be afforded access to the books and records of
      any foreign banking institution employed as a foreign sub-custodian
      insofar as such books and records relate to the performance of such
      foreign banking institution under its agreement with the Custodian. 

3.7   REPORTS BY CUSTODIAN. The Custodian will supply to the Fund from time to
      time, as mutually agreed upon, statements in respect of the securities
      and other assets of the Portfolio(s) held by foreign sub-custodians,
      including but not limited to an identification of entities having
      possession of the Portfolio(s) securities and other assets and advices or
      notifications of any transfers of securities to or from each custodial
      account maintained by a 


                                          11
<PAGE>

      foreign banking institution for the Custodian on behalf of each
      applicable Portfolio indicating, as to securities acquired for a
      Portfolio, the identity of the entity having physical possession of such
      securities.

3.8   TRANSACTIONS IN FOREIGN CUSTODY ACCOUNT. (a) Except as otherwise provided
      in paragraph (b) of this Section 3.8, the provision of Sections 2.2 and
      2.7 of this Contract shall apply, MUTATIS MUTANDIS to the foreign
      securities of the Fund held outside the United States by foreign
      sub-custodians.
      
      (b) Notwithstanding any provision of this Contract to the contrary,
      settlement and payment for securities received for the account of each
      applicable Portfolio and delivery of securities maintained for the
      account of each applicable Portfolio may be effected in accordance with
      the customary established securities trading or securities processing
      practices and procedures in the jurisdiction or market in which the
      transaction occurs, including, without limitation, delivering securities
      to the purchaser thereof or to a dealer therefor (or an agent for such
      purchaser or dealer) against a receipt with the expectation of receiving
      later payment for such securities from such purchaser or dealer.
      (c) Securities maintained in the custody of a foreign sub-custodian may
      be maintained in the name of such entity's nominee to the same extent as
      set forth in Section 2.3 of this Contract, and the Fund agrees to hold
      any such nominee harmless from any liability as a holder of record of
      such securities.

3.9   LIABILITY OF FOREIGN SUB-CUSTODIANS. Each agreement pursuant to which the
      Custodian employs a foreign banking institution as a foreign
      sub-custodian shall require the institution to exercise reasonable care
      in the performance of its duties and to indemnify, and hold harmless, the
      Custodian and the Fund from and against any loss, damage, cost, expense,
      liability or claim arising out of or in connection with the institution's
      performance of such obligations. At the election of the Fund, it shall be
      entitled to be subrogated to the rights of the Custodian with respect to
      any claims against a foreign banking institution as a consequence of any
      such loss, damage, cost, expense, liability or claim if and to the extent
      that the Fund has not been made whole for any such loss, damage, cost,
      expense, liability or claim. 

3.10  LIABILITY OF CUSTODIAN. The Custodian shall be liable for the acts or
      omissions of a foreign banking institution to the same extent as set
      forth with respect to sub-custodians generally in this Contract and,
      regardless of whether assets are maintained in the custody of a foreign
      banking institution, a foreign securities depository or a branch of a
      U.S. bank as contemplated by paragraph 3.13 hereof, the Custodian shall
      not be liable for any loss, damage, cost, expense, liability or claim
      resulting from nationalization, expropriation, currency restrictions, or
      acts of war or terrorism or any loss where the sub-custodian has
      otherwise exercised reasonable care. Notwithstanding the foregoing
      provisions of this paragraph 3.10, in delegating custody duties to State
      Street London Ltd., the Custodian shall not be relieved of any
      responsibility to the Fund for any loss due to such delegation, except
      such loss as may result from (a) political risk (including, but not
      limited to, exchange 


                                          12
<PAGE>

      control restrictions, confiscation, expropriation, nationalization,
      insurrection, civil strife or armed hostilities) or (b) other losses
      (excluding a bankruptcy or insolvency of State Street London Ltd. not
      caused by political risk) due to Acts of God, nuclear incident or other
      losses under circumstances where the Custodian and State Street London
      Ltd. have exercised reasonable care.

3.11  REIMBURSEMENT FOR ADVANCES. If the Fund requires the Custodian to advance
      cash or securities for any purpose for the benefit of a Portfolio
      including the purchase or sale of foreign exchange or of contracts for
      foreign exchange, or in the event that the Custodian or its nominee shall
      incur or be assessed any taxes, charges, expenses, assessments, claims or
      liabilities in connection with the performance of this Contract, except
      such as may arise from its or its nominee's own negligent action,
      negligent failure to act or willful misconduct, any property at any time
      held for the account of the applicable Portfolio shall be security
      therefor and should the Fund fail to repay the Custodian promptly, the
      Custodian shall be entitled to utilize available cash and to dispose of
      such Portfolio's assets to the extent necessary to obtain reimbursement.

3.12  MONITORING RESPONSIBILITIES. The Custodian shall furnish annually to the
      Fund, during the month of June, information concerning the foreign
      sub-custodians employed by the Custodian. Such information shall be
      similar in kind and scope to that furnished to the Fund in connection
      with the initial approval of this Contract. In addition, the Custodian
      will promptly inform the Fund in the event that the Custodian learns of a
      material adverse change in the financial condition of a foreign
      sub-custodian or any material loss of the assets of the Fund or in the
      case of any foreign sub-custodian not the subject of an exemptive order
      from the Securities and Exchange Commission is notified by such foreign
      sub-custodian that there appears to be a substantial likelihood that its
      shareholders' equity will decline below $200 million (U.S. dollars or the
      equivalent thereof) or that its shareholders' equity has declined below
      $200 million (in each case computed in accordance with generally accepted
      U.S. accounting principles).

3.13  BRANCHES OF U.S. BANKS. (a) Except as otherwise set forth in this
      Contract, the provisions hereof shall not apply where the custody of the
      Portfolios assets are maintained in a foreign branch of a banking
      institution which is a "bank" as defined by Section 2(a)(5) of the
      Investment Company Act of 1940 meeting the qualification set forth in
      Section 26(a) of said Act. The appointment of any such branch as a
      sub-custodian shall be governed by paragraph 1 of this Contract.

      (b) Cash held for each Portfolio of the Fund in the United Kingdom shall
      be maintained in an interest bearing account established for the Fund
      with the Custodian's London branch, which account shall be subject to the
      direction of the Custodian, State Street London Ltd. or both.

      obligations now or hereafter imposed on the Fund or the Custodian as
      custodian of the Fund by the tax law of the United States of America or
      any state or political subdivision thereof. It shall be the
      responsibility of the Fund to notify the Custodian of the obligations
      imposed on the Fund or the Custodian as custodian of the Fund by the tax
      law of jurisdictions other than those mentioned in the above sentence,
      including responsibility for withholding and other taxes, assessments or
      other governmental charges, certifications and governmental reporting.
      The sole responsibility of the Custodian with regard to such tax law
      shall be to use reasonable efforts to assist the Fund with respect to any
      claim for exemption or refund under the tax law of jurisdictions for
      which the Fund has provided such information.

4.    PAYMENTS FOR SALES OR REPURCHASES OR REDEMPTIONS OF SHARES OF THE FUND

      The Custodian shall receive from the distributor for the Shares or from
the Transfer Agent of the Fund and deposit into the account of the appropriate
Portfolio such payments as are received for Shares of that Portfolio issued or
sold from time to time by the Fund. The Custodian will provide timely
notification to the Fund on behalf of each such Portfolio and the Transfer Agent
of any receipt by it of payments for Shares of such Portfolio.

      From such funds as may be available for the purpose but subject to the
limitations of the Declaration of Trust and any applicable votes of the Board of
Trustees of the Fund pursuant thereto, the Custodian shall, upon receipt of
instructions from the Transfer Agent, make funds available for payment to
holders of Shares who have delivered to the Transfer Agent a request for
redemption or repurchase of their Shares. In connection with the redemption or
repurchase of Shares of a Portfolio, the Custodian is authorized upon receipt of
instructions from the Transfer Agent to wire funds to or through a commercial
bank designated by the redeeming shareholders. In connection with the redemption
or repurchase of Shares of the Fund, the Custodian shall honor checks drawn on
the Custodian by a holder of Shares, which checks have been furnished by the
Fund to the holder of Shares, when presented to the Custodian in accordance with
such procedures and controls as are mutually agreed upon from time to time
between the Fund and the Custodian.

5. PROPER INSTRUCTIONS

      Proper Instructions as used throughout this Contract means a writing
signed or initialled by one or more person or persons as the Board of Trustees
shall have from time to time authorized. Each such writing shall set forth the
specific transaction or type of transaction involved, including a specific
statement of the purpose for which such action is requested. Oral instructions
will be considered Proper Instructions if the Custodian reasonably believes
them to have been given by a person authorized to give such instructions with
respect to the transaction involved. The Fund shall cause all oral
instructions to be confirmed in writing. Upon receipt of a certificate of the
Secretary or an Assistant Secretary as to the authorization by the Board of
Trustees of the Fund accompanied by a detailed description of procedures
approved by the Board of Trustees, Proper Instructions may include
communications effected directly between electro-mechanical or electronic
devices provided that the Board of Trustees and the Custodian are satisfied
that such procedures afford


                                          14
<PAGE>

adequate safeguards for the Portfolios' assets. For purposes of this Section,
Proper Instructions shall include instructions received by the Custodian
pursuant to any three-party agreement which requires a segregated asset account
in accordance with Section 2.12.

6.    ACTIONS PERMITTED WITHOUT EXPRESS AUTHORITY

      The Custodian may in its discretion, without express authority from the
Fund on behalf of each applicable Portfolio:
      
      1)    make payments to itself or others for minor expenses of handling
            securities or other similar items relating to its duties under this
            Contract, PROVIDED that all such payments shall be accounted for to
            the Fund on behalf of the Portfolio;
      
      2)    surrender securities in temporary form for securities in definitive
            form;

            with the sale, exchange, substitution, purchase, transfer and other
            dealings with the securities and property of the Portfolio except
            as otherwise directed by the Board of Trustees of the Fund.

7.    EVIDENCE OF AUTHORITY

      The Custodian shall be protected in acting upon any instructions, notice,
request, consent, certificate or other instrument or paper believed by it to be
genuine and to have been properly executed by or on behalf of the Fund. The
Custodian may receive and accept a certified copy of a vote of the Board of
Trustees of the Fund as conclusive evidence (a) of the authority of any person
to act in accordance with such vote or (b) of any determination or of any
action by the Board of Trustees pursuant to the Declaration of Trust as
described in such vote, and such vote may be considered as in full force and
effect until receipt by the Custodian of written notice to the contrary.

8.    DUTIES OF CUSTODIAN WITH RESPECT TO THE BOOKS OF ACCOUNT AND CALCULATION
      OF NET ASSET VALUE AND NET INCOME

      The Custodian shall cooperate with and supply necessary information to
the entity or entities appointed by the Board of Trustees of the Fund to keep
the books of account of each Portfolio and/or compute the net asset value per
share of the outstanding shares of each Portfolio or, if directed in writing to
do so by the Fund on behalf of the Portfolio, shall itself keep such books of
account and/or compute such net asset value per share. If so directed, the
Custodian shall also calculate daily the net income of the Portfolio as
described in the Fund's currently effective prospectus related to such Portfolio
and shall advise the Fund and the Transfer Agent daily of the total amounts of
such net income and, if instructed in writing by an officer of the Fund to do
so,


                                          15
<PAGE>

shall advise the Transfer Agent periodically of the division of such net income
among its various components. The calculations of the net asset value per share
and the daily income of each Portfolio shall be made at the time or times
described from time to time in the Fund's currently effective prospectus related
to such Portfolio.

9.    RECORDS

      The Custodian shall with respect to each Portfolio create and maintain 
all records relating to its activities and obligations under this Contract 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. All such records shall be the property of 
the Fund and shall at all times during the regular business hours of the 
Custodian be open for inspection by duly authorized officers, employees or 
agents of the Fund and employees and agents of the Securities and Exchange 
Commission. The Custodian shall, at the Fund's request, supply the Fund with 
a tabulation of securities owned by each Portfolio and held by the Custodian 
and shall, when requested to do so by the Fund and for such compensation as 
shall be agreed upon between the Fund and the Custodian, include certificate 
numbers in such tabulations.

10.   OPINION OF FUND'S INDEPENDENT ACCOUNTANT

      The Custodian shall take all reasonable action, as the Fund on behalf of
each applicable Portfolio may from time to time request, to obtain from year to
year favorable opinions from the Fund's independent accountants with respect to
its activities hereunder in connection with the preparation of the Fund's Form
N-1A,, and Form N-SAR or other annual reports to the Securities and Exchange
Commission and with respect to any other requirements of such Commission.

11.   REPORTS TO FUND BY INDEPENDENT PUBLIC ACCOUNTANTS

      The Custodian shall provide the Fund, on behalf of each of the Portfolios
at such times as the Fund may reasonably require, with reports by independent
public accountants on the accounting system, internal accounting control and
procedures for safeguarding securities, futures contracts and options on futures
contracts, including securities deposited and/or maintained in a Securities
System, relating to the services provided by the Custodian under this Contract;
such reports, shall be of sufficient scope and in sufficient detail, as may
reasonably be required by the Fund to provide reasonable assurance that any
material inadequacies would be disclosed by such examination, and, if there are
no such inadequacies, the reports shall so state.

12.   COMPENSATION OF CUSTODIAN

13.   RESPONSIBILITY OF CUSTODIAN

      So long as and to the extent that it is in the exercise of reasonable
care, the Custodian shall not be responsible for the title, validity or
genuineness of any property or evidence of title thereto received by it or
delivered by it pursuant to this Contract and shall be held harmless in acting
upon any notice, request, consent, certificate or other instrument reasonably
believed by it to be genuine and to be signed by the proper party or parties,
including any futures commission merchant acting pursuant to the terms of a
three-party futures or options agreement. The Custodian shall be held to the
exercise of reasonable care in carrying out the provisions of this Contract, but
shall be kept indemnified by and shall be without liability to the Fund for any
action taken or omitted by it in good faith without negligence. It shall be
entitled to rely on and may act upon advice of counsel (who may be counsel for
the Fund) on all matters, and shall be without liability for any action
reasonably taken or omitted pursuant to such advice.

      Except as may arise from the Custodian's own negligence or willful
misconduct or the negligence or willful misconduct of a sub-custodian or agent,
the Custodian shall be without liability to the Fund for any loss, liability,
claim or expense resulting from or caused by; (i) events or circumstances beyond
the reasonable control of the Custodian or any sub-custodian or Securities
System or any agent or nominee of any of the foregoing, including, without
limitation, nationalization or expropriation, imposition of currency controls or
restrictions, the interruption, suspension or restriction of trading on or the
closure of any securities market, power or other mechanical or technological
failures or interruptions, computer viruses or communications disruptions, acts
of war or terrorism, riots, revolutions, work stoppages, natural disasters or
other similar events or acts; (ii) errors by the Fund or the Investment Advisor
in their instructions to the Custodian provided such instructions have been in
accordance with this Contract; (iii) the insolvency of or acts or omissions by a
Securities System; (iv) any delay or failure of any broker, agent or
intermediary, central bank or other commercially prevalent payment or clearing
system to deliver to the Custodian's sub-custodian or agent securities purchased
or in the remittance or payment made in connection with securities sold; (v) any
delay or failure of any company, corporation, or other body in charge or
registering or transferring securities in the name of the Custodian, the Fund,
the Custodian's sub-custodians, nominees or agents or any consequential losses
arising out of such delay or failure to transfer such securities including
non-receipt of bonus, dividends and rights and other accretions or benefits;
(vi) delays or inability to perform its duties due to any disorder in market
infrastructure with respect to any particular security or Securities System; and
(vii) any provision of any present or future law or regulation or order of the
United States of America, or any state thereof, or any other country, or
political subdivision thereof or of any court of competent jurisdiction.

      The Custodian shall be liable for the acts or omissions of a foreign
banking institution to the same extent as set forth with respect to
sub-custodians generally in this Contract.

      If the Fund on behalf of the Portfolio requires the Custodian to take any
action with respect to securities, which action involves the payment of money or
which action may, in the opinion of the Custodian, result in the Custodian or
its nominee assigned to the Fund or the Portfolio being


                                          17
<PAGE>

liable for the payment of money or incurring liability of some other form, the
Fund on behalf of the Portfolio, as a prerequisite to requiring the Custodian to
take such action, shall provide indemnity to the Custodian in an amount and form
satisfactory to it.

      If the Fund requires the Custodian, its affiliates, subsidiaries or
agents, to advance cash or securities for any purpose (including but not limited
to securities settlements, foreign exchange contracts and assumed settlement) or
in the event that the Custodian or its nominee shall incur or be assessed any
taxes, charges, expenses, assessments, claims or liabilities in connection with
the performance of this Contract, except such as may arise from its or its
nominee's own negligent action, negligent failure to act or willful misconduct,
any property at any time held for the account of the applicable Portfolio shall
be security therefor and should the Fund fail to repay the Custodian promptly,
the Custodian shall be entitled to utilize available cash and to dispose of such
Portfolio's assets to the extent necessary to obtain reimbursement.

      In no event shall the Custodian be liable for indirect, special or
consequential damages.

14.   EFFECTIVE PERIOD, TERMINATION AND AMENDMENT

      This Contract shall become effective as of its execution, shall continue
in full force and effect until terminated as hereinafter provided, may be
amended at any time by mutual agreement of the parties hereto and may be

postage prepaid to the other party, such termination to take effect not sooner
than thirty (30) days after the date of such delivery or mailing; PROVIDED,
however that the Custodian shall not with respect to a Portfolio act under
Section 2.10 hereof in the absence of receipt of an initial certificate of the
Secretary or an Assistant Secretary that the Board of Trustees of the Fund has
approved the initial use of a particular Securities System by such Portfolio, as
required by Rule 17f-4 under the Investment Company Act of 1940, as amended and
that the Custodian shall not with respect to a Portfolio act under Section 2.11
hereof in the absence of receipt of an initial certificate of the Secretary or
an Assistant Secretary that the Board of Trustees has approved the initial use
of the Direct Paper System by such Portfolio; PROVIDED FURTHER, however, that
the Fund shall not amend or terminate this Contract in contravention of any
applicable federal or state regulations, or any provision of the Declaration of
Trust, and further provided, that the Fund on behalf of one or more of the
Portfolios may at any time by action of its Board of Trustees (i) substitute
another bank or trust company for the Custodian by giving notice as described
above to the Custodian, or (ii) immediately terminate this Contract in the event
of the appointment of a conservator or receiver for the Custodian by the
Comptroller of the Currency or upon the happening of a like event at the
direction of an appropriate regulatory agency or court of competent
jurisdiction.

Portfolio shall pay to the Custodian such compensation as may be due as of the
date of such termination and shall likewise reimburse the Custodian for its
costs, expenses and disbursements.

15.   SUCCESSOR CUSTODIAN

      If a successor custodian for the Fund, of one or more of the Portfolios
shall be appointed by the Board of Trustees of the Fund, the Custodian shall,
upon termination, deliver to such successor custodian at the office of the
Custodian, duly endorsed and in the form for transfer, all securities of each
applicable Portfolio then held by it hereunder and shall transfer to an account
of the successor custodian all of the securities of each such Portfolio held in
a Securities System.

      If no such successor custodian shall be appointed, the Custodian shall,
in like manner, upon receipt of a certified copy of a vote of the Board of
Trustees of the Fund, deliver at the office of the Custodian and transfer such
securities, funds and other properties in accordance with such vote.

      In the event that no written order designating a successor custodian or
certified copy of a vote of the Board of Trustees shall have been delivered to
the Custodian on or before the date when such termination shall become
effective, then the Custodian shall have the right to deliver to a bank or trust
company, which is a "bank" as defined in the Investment Company Act of 1940,
doing business in Boston, Massachusetts, of its own selection, having an
aggregate capital, surplus, and undivided profits, as shown by its last
published report, of not less than $25,000,000, all securities, funds and other
properties held by the Custodian on behalf of each applicable Portfolio and all
instruments held by the Custodian relative thereto and all other property held
by it under this Contract on behalf of each applicable Portfolio and to transfer
to an account of such successor custodian all of the securities of each such
Portfolio held in any Securities System. Thereafter, such bank or trust company
shall be the successor of the Custodian under this Contract.

      In the event that securities, funds and other properties remain in the
possession of the Custodian after the date of termination hereof owing to
failure of the Fund to procure the certified copy of the vote referred to or of
the Board of Trustees to appoint a successor custodian, the Custodian shall be
entitled to fair compensation for its services during such period as the
Custodian retains possession of such securities, funds and other properties and
the provisions of this Contract relating to the duties and obligations of the
Custodian shall remain in full force and effect.

16.   INTERPRETIVE AND ADDITIONAL PROVISIONS

      In connection with the operation of this Contract, the Custodian and the
Fund on behalf of each of the Portfolios, may from time to time agree on such
provisions interpretive of or in addition to the provisions of this Contract as
may in their joint opinion be consistent with the general tenor of this
Contract. Any such interpretive or additional provisions shall be in a writing
signed by both parties and shall be annexed hereto, PROVIDED that no such
interpretive or additional provisions shall contravene any applicable federal or
state regulations or any provision of the Declaration of Trust of the Fund. No
interpretive or additional provisions made as provided in the preceding sentence
shall be deemed to be an amendment of this Contract.

17.   ADDITIONAL FUNDS

      In the event that the Fund establishes one or more series of Shares in
addition to the International Fixed Income Fund, Emerging Markets Equity Fund
and International Equity Fund with respect to which it desires to have the
Custodian render services as custodian under the terms hereof, it shall so
notify the Custodian in writing, and if the Custodian agrees in writing to
provide such services, such series of Shares shall become a Portfolio hereunder.

18.   MASSACHUSETTS LAW TO APPLY

      This Contract shall be construed and the provisions thereof interpreted
under and in accordance with laws of The Commonwealth of Massachusetts.

19.   PRIOR CONTRACTS

      This Contract supersedes and terminates, as of the date hereof, all prior
contracts between the Fund on behalf of each of the Portfolios and the Custodian
relating to the custody of the Fund's assets.

20.   SHAREHOLDER COMMUNICATIONS ELECTION

      Securities and Exchange Commission Rule 14b-2 requires banks which hold
securities for the account of customers to respond to requests by issuers of
securities for the names, addresses and holdings of beneficial owners of
securities of that issuer held by the bank unless the beneficial owner has
expressly objected to disclosure of this information. In order to comply with
the rule, the Custodian needs the Fund to indicate whether it authorizes the
Custodian to provide the Fund's name, address, and share position to requesting
companies whose securities the Fund owns. If the Fund tells the Custodian "no",
the Custodian will not provide this information to requesting companies. If the
Fund tells the Custodian "yes" or does not check either "yes" or "no" below, the
Custodian is required by the rule to treat the Fund as consenting to disclosure
of this information for all securities owned by the Fund or any funds or
accounts established by the Fund. For the Fund's protection, the Rule prohibits
the requesting company from using the Fund's name and address for any purpose
other than corporate communications. Please indicate below whether the Fund
consents or objects by checking one of the alternatives below.

      YES [ ]     The Custodian is authorized to release the Fund's name,
                  address, and share positions.
      
      NO  [ ]     The Custodian is not authorized to release the Fund's name,
                  address, and share positions.

                               ADMINISTRATION AGREEMENT
                         SEI INSTITUTIONAL INVESTMENTS TRUST

    THIS AGREEMENT is made as of this 14th day of June, 1996, by and between
SEI Institutional Investments Trust, a Massachusetts business trust (the
"Trust"), and SEI Financial Management Corporation (the "Administrator"), a
Delaware Corporation.

    WHEREAS, the Trust is an open-end diversified management investment company
registered under the Investment Company Act of 1940, as amended (the "1940
Act"), consisting of several series of shares of Common Stock; and

    WHEREAS, the Trust desires the Administrator to provide, and the
Administrator is willing to provide, management and administrative services to
such portfolios of the Trust as the Trust and the Administrator may agree on
("Portfolios") and as listed on the schedules attached hereto ("Schedules") and
made a part of this Agreement, on the terms and conditions hereinafter set
forth;

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

Administrator to act as the administrator of the Portfolios and to furnish the
Portfolios with the management and administrative services as set forth in
Article 2 below. The Administrator hereby accepts such employment to perform the
duties set forth below.

    The Administrator 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.

    ARTICLE 2. ADMINISTRATIVE AND ACCOUNTING SERVICES. The Administrator shall

dealers, corporate fiduciaries, insurers, banks and persons in any other
capacity deemed to be necessary or desirable for the Portfolios' operations. The
Administrator shall provide the Trustees of the Trust with such reports
regarding investment performance and compliance with investment policies and
applicable laws, rules and regulations as they may reasonably request but shall
have no responsibility for supervising the performance by any investment adviser
or sub-adviser of its responsibilities. The Administrator may appoint a

Administrator hereunder.

    The Administrator shall provide the Trust with administrative services,
regulatory reporting, fund accounting and related portfolio accounting services,

to time, reasonably request and the Administrator shall, from time to time,
reasonably determine to be necessary to perform its obligations under this
Agreement. In addition, at the request of the Trust's Board of Trustees (the
"Trustees"), the Administrator shall make reports to the Trustees concerning the
performance of its obligations hereunder.


                                                                               1

    ARTICLE 3. ALLOCATION OF CHARGES AND EXPENSES.

    (A)  THE ADMINISTRATOR. The Administrator shall furnish at its own expense
the executive, supervisory and clerical personnel necessary to perform its
obligations under this Agreement. The Administrator 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 Administrator or any affiliated
corporation of the Administrator; provided, however, that unless otherwise
specifically provided, the Administrator shall not be obligated to pay the
compensation of any employee of the Trust retained by the Trustees of the Trust
to perform services on behalf of the Trust.


                                                                              3

charges of investment advisers to the Trust.

    ARTICLE 4. COMPENSATION OF THE ADMINISTRATOR.

    (A)  ADMINISTRATION FEE. For the services to be rendered, the facilities
furnished and the expenses assumed by the Administrator pursuant to this
Agreement, the Trust shall pay to the Administrator compensation at an annual
rate specified in the Schedules. Such compensation shall be calculated and
accrued daily, and paid to the Administrator monthly.

    If this Agreement becomes effective subsequent to the first day of a month
or terminates before the last day of a month, the Administrator'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 Administrator's compensation for the preceding month shall
be made promptly.

    (B)  COMPENSATION FROM TRANSACTIONS. The Trust hereby authorizes any entity
or person associated with the Administrator 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).

    (C)  SURVIVAL OF COMPENSATION RATES. All rights of compensation under this
Agreement for services performed as of the termination date shall survive the
termination of this Agreement.

    ARTICLE 5. LIMITATION OF LIABILITY OF THE ADMINISTRATOR. The duties of the
Administrator shall be confined to those expressly set forth herein, and no
implied duties are assumed by or may be asserted against the Administrator
hereunder. The Administrator 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 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 law which
cannot be waived or modified hereby. (As used in this Article 5, the term
"Administrator" shall include directors, officers, employees and other agents of
the Administrator as well as that corporation itself..)

    So long as the Administrator, or its agents, acts in good faith and with
due diligence and without negligence, the Trust assumes full responsibility and
shall indemnify the Administrator 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


                                                                              4
<PAGE>

(including reasonable investigation expenses) arising directly or indirectly out
of said administration, transfer agency, and dividend disbursing relationships
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
Administrator 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 Administrator 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
hereunder.

    The Trust shall be entitled to participate at its own expense or, if it so
elects, to assume the defense of any suit brought to enforce any claims subject
to this indemnity provision. If the Trust elects to assume the defense of any
such claim, the defense shall be conducted by counsel chosen by the Trust and
satisfactory to the Administrator, whose approval shall not be unreasonably
withheld. In the event that the Trust elects to assume the defense of any suit
and retain counsel, the Administrator shall bear the fees and expenses of any
additional counsel retained by it. If the Trust does not elect to assume the
defense of a suit, it will reimburse the Administrator for the reasonable fees
and expenses of any counsel retained by the Administrator.

    The Administrator 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
Administrator's duties, and the Administrator 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 Administrator shall be protected in acting upon any document
which it reasonably believes to be genuine and to have been signed or presented
by the proper person or persons. Nor shall the Administrator be held to have
notice of any change of authority of any officers, employee or agent of the
Trust until receipt of written notice thereof from the Trust.

    ARTICLE 6. ACTIVITIES OF THE ADMINISTRATOR. The services of the
Administrator rendered to the Trust are not to be deemed to be exclusive. The
Administrator is free to render such services to others and to have other
businesses and interests. It is understood that Trustees, officers, employees
and Shareholders of the Trust are or may be or become interested in the
Administrator, as directors, officers, employees and shareholders or otherwise
and that directors, officers, employees and shareholders of the Administrator
and its counsel are or may be or become similarly interested in the Trust, and
that the Administrator may be or become interested in the Trust as a Shareholder
or otherwise.

    ARTICLE 7. CONFIDENTIALITY. The Administrator agrees on behalf of itself
and its employees to treat confidentially all records and other information
relative to the Trust and its prior, present or potential Shareholders and
relative to the Adviser and its prior, present or potential customers, except,
after prior notification to and approval in writing by the Trust, which approval
shall not be unreasonably withheld and may not be withheld where the
Administrator may be exposed to civil or criminal contempt proceedings for
failure to


                                                                              5
<PAGE>

comply, when requested to divulge such information by duly constituted
authorities, or when so requested by the Trust.

    ARTICLE 8. EQUIPMENT FAILURES. In the event of equipment failures beyond
the Administrator's control, the Administrator shall, at no additional expense
to the Trust, take reasonable steps to minimize service interruptions but shall
have no liability with respect thereto. The Administrator shall develop and
maintain a plan for recovery from equipment failures which may include
contractual arrangements with appropriate parties making reasonable provision
for emergency use of electronic data processing equipment to the extent
appropriate equipment is available.

    ARTICLE 9. COMPLIANCE WITH GOVERNMENTAL RULES AND REGULATIONS. The
Administrator undertakes to comply with all applicable requirements of the 1933
Act, the 1934 Act, the 1940 Act and any laws, rules and regulations of
governmental authorities having jurisdiction with respect to the duties to be
performed by the Administrator hereunder.

    ARTICLE 10. DURATION AND TERMINATION OF THIS AGREEMENT. This Agreement
shall become effective on the date set forth in the Schedules and shall remain
in effect for the initial term of the Agreement (the "Initial Term") and each
renewal term thereof (each, a "Renewal Term"), each as set forth in the
Schedules, unless terminated in accordance with the provisions of this Article
10. This Agreement may be terminated only: (a) by the mutual written agreement
of the parties; (b) by either party hereto on 90 days' written notice, as of the
end of the Initial Term or the end of any Renewal Term; (c) by either party

has not remedied such breach by the specified date; (d) effective upon the
liquidation of the Administrator; or (e) as to any Portfolio or the Trust,
effective upon the liquidation of such Portfolio or the Trust, as the case may
be. For purposes of this Article 10, the term "liquidation" shall mean a
transaction in which the assets of the Administrator, the Trust or a Portfolio
are sold or otherwise disposed of and proceeds therefrom are distributed in cash
to the shareholders in complete liquidation of the interests of such
shareholders in the entity.

    This Agreement shall not be assignable by the Administrator, without the
prior written consent of the Trust, except to an entity that is controlled by,
or under common control, with, the Administrator.

    ARTICLE 11. AMENDMENTS. This Agreement or any part hereof may be changed or
waived only by an instrument in writing signed by the party against which
enforcement of such change or waiver is sought.

    ARTICLE 12. CERTAIN RECORDS. The Administrator shall maintain customary 
records in connection with its duties as specified in this Agreement. Any 
records required to be maintained and preserved pursuant to Rules 31a-1 and 
31a-2 under the 1940 Act which are prepared or maintained by the 
Administrator on behalf of the Trust shall be prepared and maintained at the 
expense of the Administrator, but shall be the property of the Trust and will 
be made available to or surrendered promptly to the Trust on request.

    In case of any request or demand for the inspection of such records by
another party, the Administrator shall notify the Trust and follow the Trust's
instructions as to permitting or refusing such inspection; provided that the
Administrator may exhibit such records to any person in any case where it is
advised by its counsel that it


                                                                              6
<PAGE>

may be held liable for failure to do so, unless (in cases involving potential
exposure only to civil liability) the Trust has agreed to indemnify the
Administrator against such liability.

    ARTICLE 13. DEFINITIONS OF CERTAIN TERMS. The terms "interested person" and
"affiliated person," when used in this Agreement, shall have the respective
meanings specified in the 1940 Act and the rules and regulations thereunder,
subject to such exemptions as may be granted by the Securities and Exchange
Commission.

    ARTICLE 14. NOTICE. 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 c/o Kevin P. Robins, General Counsel, SEI Financial Management
Corporation, 680 East Swedesford Road, Wayne, PA 19087; and if to the
Administrator at 680 East Swedesford Road, Wayne, PA 19087-1658.

    ARTICLE 15. GOVERNING LAW. This Agreement shall be construed in accordance
with the laws of the Commonwealth of Massachusetts and the applicable provisions
of the 1940 Act. To the extent that the applicable laws of the Commonwealth of
Massachusetts, or any of the provisions herein, conflict with the applicable
provisions of the 1940 Act, the latter shall control.

    ARTICLE 16. MULTIPLE ORIGINALS. 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.

    ARTICLE 17. LIMITATION OF LIABILITY. The Administrator is hereby expressly
put on notice of the limitation of liability as set forth in Article XI of the
Trust's Declaration of Trust and agrees that the obligations pursuant to this
Agreement of a particular Portfolio and of the Trust with respect to that
Portfolio shall be limited solely to the assets of that Portfolio, and the
Administrator shall not seek satisfaction of any such obligation from any other
Portfolio, the shareholders of any Portfolio, the Trustees, officers, employees
or agents of the Trust, or any of them.


                                                                              7
<PAGE>

    ARTICLE 18. BINDING AGREEMENT. This Agreement, and the rights and
obligations of the parties and the Portfolios hereunder, shall be binding on,
and inure to the benefit of, the parties and the Portfolios and the respective
successors and assigns of each of them.

    IN WITNESS WHEREOF, the parties hereto have executed and delivered this
Agreement as of the day and year first above written.
