SEI Institutional Managed Trust -- March 31, 1995 (Unaudited)



1. ORGANIZATION
 
SEI Institutional Managed Trust (the "Trust") is organized as a Massachusetts
business trust under a Declaration of Trust dated October 20, 1986.
 
2. SIGNIFICANT ACCOUNTING POLICIES
 
The Trust is registered under the Investment Company Act of 1940, as amended,
as an open-end investment company with twelve diversified Portfolios and one
non-diversified portfolio (the "Portfolios"): Large Cap Value, Large Cap
Growth, Small Cap Value, Small Cap Growth, Mid-Cap Growth, Capital Apprecia-
tion, Equity Income, Balanced, Capital Growth, Core Fixed Income, Bond, and
High Yield Bond. The Real Estate Securities Portfolio had not commenced opera-
tions as of March 31, 1995. The Trust is registered to offer Class A, Class B
and Class D shares of the Large Cap Value, Large Cap Growth, Small Cap Value,
Small Cap Growth, Mid-Cap Growth, Capital Appreciation, Equity Income, Bal-
anced, Core Fixed Income, Bond, and High Yield Bond Portfolios. The following
is a summary of the significant accounting policies followed by the Trust.
  Security Valuation--Investments in equity securities which are traded on a
national securities exchange (or reported on NASDAQ national market system) are
stated at the last quoted sales price if readily available for such equity se-
curities on each business day; other equity securities traded in the over-the-
counter market and listed equity securities for which no sale was reported on
that date are stated at the last quoted bid price. Debt obligations with re-
maining maturities in excess of sixty days are valued at the most recently
quoted bid price. Debt obligations with remaining maturities of sixty days or
less are valued at their amortized cost.
  Federal Income Taxes--It is each Portfolio's intention to qualify as a regu-
lated investment company for Federal income tax purposes and distribute all of
its taxable income (including net capital gains). Accordingly, no provision for
Federal income taxes is required.
  Net Asset Value Per Share--Net asset value per share is calculated on a daily
basis by dividing the assets of each Portfolio less its liabilities by the num-
ber of outstanding shares of the Portfolio.
  Repurchase Agreements--Securities pledged as collateral for repurchase agree-
ments are held by each Portfolio's custodian bank until maturity of the Repur-
chase Agreement. Provisions of the Agreement and procedures adopted by the Man-
ager and the Advisers of the Trust ensure that the market value of the collat-
eral, including accrued interest thereon, is sufficient in the event of default
by the counterparty. The Portfolios also invest in tri-party repurchase agree-
ments. Securities held as collateral for tri-party repurchase agreements are
maintained by the broker's custodian bank in a segregated account until matu-
rity of the repurchase agreement. Provisions of the agreements ensure that the
market value of the collateral, including accrued interest thereon, is suffi-
cient in the event of default. If the counterparty defaults and the value of
the collateral declines or if the counterparty enters into an insolvency pro-
ceeding, realization of the collateral by the Portfolios may be delayed or lim-
ited.
  Discount and Premium Amortization--All amortization is calculated using the
effective interest method over the holding period of the security. Amortization
of premiums and discounts is included in interest income.
  Classes--Class-specific expenses are borne by that class of shares. Income,
expenses, and realized and unrealized gains/losses are allocated to the respec-
tive classes on the basis of relative daily net assets.
  Distributions--Distributions from net investment income are paid to Share-
holders monthly for the Large Cap Value, Capital Appreciation, Equity Income,
Balanced, Capital Growth, Core Fixed Income, Bond, and High Yield Bond Portfo-
lios and quarterly for the Large Cap Growth, Small Cap Value, Small Cap Growth,
and Mid-Cap Growth Portfolios. Any net realized capital gains on the sales of
securities by a Portfolio are distributed annually to the Shareholders of that
Portfolio.
  Futures Contracts--The Core Fixed Income Portfolio utilized U.S. Long Bond
futures contracts to a limited extent during the period ended March 31, 1995.
Initial margin deposits of cash or securities
 
                                                                               9

NOTES TO FINANCIAL STATEMENTS (Continued)
- --------------------------------------------------------------------------------
SEI Institutional Managed Trust -- March 31, 1995 (Unaudited)


are made upon entering into futures contracts. The contracts are marked to mar-
ket daily and the resulting changes in value are accounted for as unrealized
gains and losses. Variation margin payments are paid or received, depending
upon whether unrealized losses or gains are incurred. When the contract is
closed, the Portfolio records a realized gain or loss equal to the difference
between the proceeds from (or cost of) the closing transaction and the amount
invested in the contract.
  Risks related to futures contracts include the possibility that there may not
be a liquid market for the contracts, that changes in the values of the con-
tract may not directly correlate with changes in the values of the underlying
securities, and that the counterparty to a contract may default on its obliga-
tion to perform.
  Structured Notes and Indexed Notes--The Core Fixed Income Portfolio may in-
vest in structured notes and indexed notes whose values are linked either di-
rectly or inversely to changes in foreign currency exchange rates, interest
rates, indexes, or other reference instruments. The values of these instruments
may be more volatile than the rates, indexes or instruments to which they re-
fer, but any loss is limited to the amount of the original investment.
  Other--Security transactions are recorded on the trade date of the security
purchase or sale. Cost used in determining net realized capital gains and
losses on the sale of securities are those of the specific securities sold.
Dividend income is recognized on the ex-dividend date, and interest income is
recognized on the accrual basis.

net assets of the Equity Income Portfolio. The Manager and Merus have agreed to
waive their fees proportionately so that the total annual expenses of the Port-
folio will not exceed the lower of the maximum limitations established by cer-
tain states or voluntary expense limitations adopted by the Manager
  Western Asset Management, the adviser of the Core Fixed Income Portfolio, and
Boatmen's Trust Company, the adviser of the Bond Portfolio, are parties to an
investment advisory agreements dated January 19, 1994 and December 29, 1988,
respectively. Under the investment advisory agreements, each adviser receives
an annual fee of .125% of the average daily net assets of the Portfolio.
  CS First Boston Investment Management Corporation ("CS First Boston") serves
as investment sub-adviser to the High Yield Bond Portfolio and is party to an
investment sub-advisory agreement with the Trust dated December 16, 1994. Under
the sub-advisory agreement, CS First Boston is entitled to a fee--paid monthly
by SFM--of .3375% of the average monthly market value of investments under its
management.
  SEI Financial Services Company (the "Distributor"), a wholly-owned subsidiary
of SEI Corporation and a registered broker-dealer, acts as the distributor of
the shares of the Trust under a distribution plan which provides for the Trust
to reimburse the Distributor for distribution expenses. Such expenses may not
exceed .30% of the average daily net assets of the Trust's Class A shares. Dis-
tribution expenses include, among other items, the compensation and benefits of
sales personnel incurred by the Distributor in connection with the promotion
and sale of shares. Distribution expenses are allocated among the Portfolios,
on the basis of their relative average daily net assets. In addition, Portfo-
lios with Class B shares and Class D shares, have separate distribution plans
that provide for additional payments to the Distributor of .30% of each of the
Class B and Class D shares' average daily net assets.
  The Distribution Agreement between the Distributor and the Trust provides
that the Distributor may receive compensation on portfolio transactions ef-
fected for the Trust in accordance with the rules of the Securities and Ex-
change Commission ("SEC"). Accordingly, it is expected that portfolio transac-
tions may result in brokerage commissions being paid to the Distributor. The
SEC rules require that such commissions not exceed usual and customary broker-
age commissions.
 
4. ORGANIZATIONAL COSTS AND TRANSACTIONS WITH AFFILIATES
 
Organizational costs have been capitalized by the Fund and are being amortized
over sixty months commencing with operations. In the event any of the initial
shares are redeemed by any holder thereof during the period that the fund is
amortizing its organizational costs, the redemption proceeds payable to the
holder thereof by the Fund will be reduced by the unamortized organizational
costs in the same ratio as the number of initial shares being redeemed bears to
the number of initial shares outstanding at the time of the redemption.
  Certain officers and/or trustees of the Trust are also officers of the Manag-
er. The Trust pays each unaffiliated Trustee an annual fee for attendance of
quarterly, interim, and committee meetings. Compensation of officers and affil-
iated Trustees of the Trust is paid by the Manager.
  Each of the Portfolios also used the Distributor as an agent in placing re-
purchase agreements. For this service the Distributor retains a portion of the
benefit as a commission. Such commissions for repurchase agreements placed dur-
ing the period ended March 31, 1995, were nominal in the aggregate.

  The market values of the Intermediate Bond, Bond and High Yield Bond Portfo-
lios' investments will change in response to interest rate changes and other
factors. During periods of falling interest rates, the values of fixed income
securities generally rise. Conversely, during periods of rising interest rates,
the values of such securities generally decline. Changes by recognized rating
agencies in the ratings of any fixed income security and in the ability of an
issuer to make payments of interest and principal may also affect the value of
these investments.
  At March 31, 1995 the following Portfolios had available realized capital
losses to offset future net capital gains through fiscal year ended 2003.

Item 27. Indemnification:

Article VIII of the Agreement and Declaration of Trust filed as Exhibit 1 to the
Registration Statement is incorporated by reference. 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.

                                 June 19, 1995

                                  Introduction

          SEI Institutional Managed Trust (the "Trust"), a registered investment
company that currently consists of thirteen (13) separately managed portfolios 
(the Core Fixed Income Portfolio, Bond Portfolio, High Yield Bond Portfolio, 
Large Cap Value Portfolio, Large Cap Growth Portfolio, Small Cap Value 
Portfolio, Small Cap Growth Portfolio, Capital Appreciation Portfolio, Equity 
Income Portfolio, Balanced Portfolio, Mid-Cap Growth Portfolio, Capital Growth 
Portfolio and Real Estate Securities Portfolio) and that may consist of 
additional portfolios in the future as listed on Schedule A hereto (each a 
"Portfolio" and, collectively, the "Portfolios"), have elected to rely on Rule 
18f-3 under the Investment Company Act of 1940, as amended (the "1940 Act") in 
offering multiple classes of units of beneficial interest ("shares") in each 
Portfolio. The Plan sets forth the differences among classes, including 
shareholder services, distribution arrangements, expense allocations, and 
conversion or exchange options.

A.  Attributes of Share Classes

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

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

the servicing agreements relating to such class, and will have separate voting 
rights on any matter submitted to shareholders in which the interests of that 
class differ from the interests of any other class.

B.  Expense Allocations

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

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

C.  Amendment of Plan; Periodic Review

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

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

                            DISTRIBUTION AGREEMENT
                    TRUSTFUNDS INSTITUTIONAL MANAGED TRUST

     THIS AGREEMENT is made as of this 22nd day of January, 1987 between 
TrustFunds Institutional Managed 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 ("SEC") under the Investment Company Act of 
1940, as amended ("1940 Act"), and its Units are registered with the SEC under 
the Securities Act of 1933, as amended ("1933 Act"); and

     WHEREAS 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 Distributor hereby agree as follows:

     ARTICLE 1. Sale of Units. The Trust grants to the Distributor the exclusive
                -------------
right to sell Units of the Trust at the net asset value per Unit, 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 ("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, to obtain purchasers for Units 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.

     ARTICLE 3. 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 Unitholder reports or other material 
that may be prepared by or on behalf of the Trust for the Distributor's use. The
Distributor may prepare and distribute sales literature and other material as it
may deem appropriate, provided that such literature and materials have been 
approved by the Trust prior to their use.

     ARTICLE 4.  Registration of Units.  The Trust agrees that it will take all
                 ---------------------
action necessary to register Units under the federal and state securities 
laws so that there will be available for sale the number of Units the 
Distributor may reasonably be expected to sell. The Trust shall make available 
to the Distributor such number of copies of its currently effective prospectus 
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 Units of the Trust.

     ARTICLE 5.  Compensation.  As compensation for the services performed and 
                 ------------
the expenses assumed by the Distributor under this Agreement, and to the extent
provided in the Trust's Distribution Plan adopted in accordance with Rule 12b-1
under the 1940 Act, the Trust shall reimburse the Distributor for (i) the cost
of prospectuses and statements of additional information, reports to
Unitholders, sales literature and other materials for potential investors, (ii)
the costs of complying with the Federal and state securities laws pertaining to
the distribution of Units, (iii) advertising, and (iv) expenses incurred in
promoting and selling Units, including expenses for travel, communication, and
compensation and benefits of sales personnel. Separate and apart from the
services and compensation provided for under this Agreement, the Distributor may
retain additional compensation that it receives from the Trust on portfolio
transactions that it effects for the Trust in accordance with applicable rules
of the Securities and Exchange Commission.

     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 Units, based upon the ground that the registration statement, 
prospectus, Unitholder reports or other information filed or made public by the 
Trust (as from time to time amended) included an untrue statement of a material
fact or omitted to state a material fact required to be stated or necessary in
order to make the statements made not misleading. However, the Trust does not
agree to indemnify the Distributor or hold it harmless to the extent that the
statement or omission was made in reliance upon, and in conformity with,
information furnished to the Trust by or on behalf of the Distributor.

     In no case (i) is the indemnity of the Trust to be deemed to protect the 
Distributor or any person against any liability to the Trust or its Unitholders 
to which the Distributor or such


                                     - 2 -
<PAGE>
 
person otherwise would be subject by reason of willful misfeasance, bad faith or
gross negligence in the performance of its duties or by reason of its reckless 
disregard of its obligations and duties under this Agreement, or (ii) is the 
Trust to be liable to the Distributor under the 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 Trustees in 
connection with the issuance or sale of any of its Units.

     ARTICLE 7. Indemnification of Trust. The Distributor covenants and agrees
                ------------------------
that it will indemnify and hold harmless the Trust and each of its Trustees and 
officers and each person, if any, who controls the Trust within the meaning of 
Section 15 of the Act, against any loss, liability, damages, claim or expense 
(including the reasonable cost of investigating or defending any alleged loss, 
liability, damages, claim or expense and reasonable counsel fees incurred in 
connection therewith) based upon the 1933 Act or any other statute or common law
and arising by reason of any person acquiring any Units, and alleging a wrongful
act of the Distributor or any of its employees or alleging that the registration
statement, prospectus, Unitholder reports or other information filed or made 
public by the Trust (as from time to time amended) included an untrue statement 
of a material fact or 

                                     - 3 -
<PAGE>
 
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 gross 
negligence in the performance of its duties or by reason of its reckless 
disregard of its obligations and duties under this Agreement, or (ii) is the 
Distributor to be liable under its indemnity agreement contained in this 
paragraph with respect to any claim made against the Trust or any person 
indemnified unless the Trust or person, as the case may be, shall have notified 
the Distributor in writing of the claim within a reasonable time after the 
summons or other first written notification giving information of the nature of 
the claim shall have been served upon the Trust or 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.

     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 Trusts' Units. 

     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 from year to year, provided that 
such annual continuance is approved by (i) either the vote of a majority of the 
Trustees of the Trust, or the vote of a majority of the outstanding voting 
securities of the Trust, and (ii) the vote of

                                     - 4 -

a majority of those Trustees of the Trust who are not parties to this Agreement 
or the Trust's Distribution Plan or interested persons of any such party 
("Qualified Trustees"), 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 SFS, by a vote of a 
majority of Qualified Trustees 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 28 State Street, Boston, Massachusetts 02109, and if to the 
Distributor, 680 E. Swedesford Road, Wayne, Pennsylvania 19087.

     ARTICLE 10. Limitation of Liability. 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 Agreement is executed on 
behalf of the Trustees of the Trust as Trustees and not individually and that 
the obligations of this instrument are not binding upon any of the Trustees, 
officers or unitholders of the Trust individually but binding only upon the 
assets and property of the Trust.

     ARTICLE 11. 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 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.

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

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

          NOW, THEREFORE, the Trustees of the Trust hereby adopt this

assets of the ProVantage Funds of the Portfolios. All expenditures pursuant to 
this Plan shall be made only pursuant to authorization by the President, any 
Vice President or the Treasurer of the Trust. If there should be more than one 
series of Trust shares, expenses incurred pursuant to this Plan shall be 
allocated among the several series of the Trust on the basis of their relative 
net asset values, unless otherwise determined by a majority of the Qualified 
Trustees.

In addition, the Trust will pay the Distributor a fee on the ProVantage Funds of
the Portfolios up to the amount set forth on Exhibit A. The Distributor may use 
this fee for (i) compensation for its services in connection with distribution 
assistance or provision of shareholder services; or (ii) payments to financial 
institutions and intermediaries such as banks, savings and loan associations, 
insurance companies and investment counselors, broker-dealers and the 
Distributor's affiliates and subsidiaries as compensation for services or 
reimbursement of expenses incurred in connection with distribution assistance or
provision of shareholder services.

          ----------
be limited to, the following:

     (b) advertising;

     (c) the costs of preparing, printing and distributing any literature used
         in connection with the offering the Trust's Shares and not covered by
         Section 3(a) of this Plan; and

     (d) expenses incurred in connection with the promotion and sale of the
         Trust's Shares including, without limitation, travel and communication
         expenses and expenses for the compensation of and benefits for sales
         personnel.

     Section 4. This Plan shall not take effect until it has been approved (a)
     ---------
by a vote of at least a majority of the outstanding voting securities of the 
Trust's ProVantage Funds Class; and (b) together with any related agreements, by
votes of the majority of both (i) the Trustees of the Trust and (ii) the 
Qualified Trustees, cast in person at a Board of Trustees meeting called for the
purpose of voting on this Plan or such agreement.

     Section 5. This Plan shall continue in effect for a period of more than one
     ---------
year after it takes effect only for so long as such continuance is specifically 
approved at least annually in the manner provided in Part (b) of Section 4 
herein for the approval of this Plan.

     Section 6. Any person authorized to direct the disposition of monies paid 
     ---------
or payable by the Trust pursuant to this Plan or any related agreement shall 
provide to the Trustees of the Trust, at least quarterly, a written report of 
the amounts so expended and the purposes for which such expenditures were made.

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

of any penalty, by the vote of a majority of the Qualified Trustees or by the 
vote of Shareholders holding a majority of the Trust's outstanding voting 
securities, on not more than 60 days written notice to any other party to the 
agreement; and (b) that such agreement shall terminate automatically in the 
event of its assignment.

     Section 9. This Plan may not be amended to increase materially the amount 
     ---------
of distribution expenses permitted pursuant to Section 2 hereof without the 
approval of Shareholders holding a majority of the outstanding voting securities
of the Trust, and all

(1) The Capital Growth and Real Estate Securities Portfolios offer only Class A
    shares.
(2) SEI Financial Management Corporation ("SFM"), in its capacity as Manager
    for each Portfolio, and certain of the investment advisers and sub-advisers
    (collectively, "advisers") have agreed to waive, on a voluntary basis, a
    portion of their fees, and the management/advisory fees shown reflect these
    voluntary waivers. Such fee waivers are voluntary and may be terminated at
    any time in the sole discretion of each entity that has agreed to waive a
    portion of its fee. Absent such fee waivers, management/advisory fees would
    be: Large Cap Value Portfolio, .70%; Large Cap Growth Portfolio, .75%;
    Small Cap Value Portfolio, 1.00%; Small Cap Growth Portfolio, 1.00%; Mid-
    Cap Growth Portfolio, .95%; Capital Appreciation Portfolio, .75%; Equity
    Income Portfolio, .75%; Balanced Portfolio, .75%; Capital Growth Portfolio,
    .50%; and Real Estate Securities Portfolio, .95%.
(3) The 12b-1 fee shown refers to each Portfolio's current 12b-1 budget for
    reimbursement of expenses and, with respect to the Capital Growth
    Portfolio, after reimbursement by SFM. SFM reserves the right to terminate
    its reimbursement at any time in its sole discretion. Absent such
    reimbursement, the 12b-1 fee would be .01% for the Capital Growth
    Portfolio. The maximum 12b-1 fees payable by Class A shares of each
    Portfolio is .30%.
(4) Other Expenses for the Large Cap Growth and Small Cap Value Portfolios are
    based on estimated amounts for the current fiscal year. Absent SFM's
    reimbursement of its management fee, other expenses for the Capital Growth
    Portfolio would be .03%. SFM reserves the right to terminate its
    reimbursement at any time in its sole discretion.
(5) Absent the voluntary fee waivers described above, total operating expenses
    for the Class A shares of the Portfolios would be: Large Cap Value
    Portfolio, .80%; Large Cap Growth Portfolio, .90%; Small Cap Value
    Portfolio, 1.12%; Small Cap Growth Portfolio, 1.11%; Mid-Cap Growth
    Portfolio, 1.06%; Capital Appreciation Portfolio, .84%; Equity Income
    Portfolio, .84%; Balanced Portfolio, .91%; Capital Growth Portfolio, .54%;
    and Real Estate Securities Portfolio, 1.05%. Additional information may be
    found under "The Advisers and Sub-Advisers" and "The Manager and
    Shareholder Servicing Agent."

</TABLE>
THE EXAMPLE SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE
EXPENSES. ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN.
 
The purpose of the expense table and example is to assist the investor in
understanding the various costs and expenses that may be directly or indirectly
borne by investors in Class A shares of the Portfolios. The information set
forth in the foregoing table and example relates only to each Portfolio's Class
A shares. Certain Portfolios also offer ProVantage Funds shares, which are
subject to the same expenses except that ProVantage Funds shares bear different
distribution costs and additional transfer agent costs and sales loads. A
person who purchases shares through a financial institution may be charged
separate fees by that institution. Additional information may be found under
"The Manager and Shareholder Servicing Agent," "The Advisers and Sub-Advisers"
and "Distribution."
 
Long-term shareholders may eventually pay more than the economic equivalent of
the maximum front-end sales charges otherwise permitted by the Rules of Fair
Practice (the "Rules") of the National Association of Securities Dealers, Inc.
("NASD").

(1) SEI Financial Management Corporation ("SFM"), in its capacity as Manager
    for each Portfolio, and certain of the investment advisers and sub-advisers
    (collectively, "advisers") have agreed to waive, on a voluntary basis, a
    portion of their fees, and the management/advisory fees shown reflect these
    voluntary waivers. Such fee waivers are voluntary and may be terminated at
    any time in the sole discretion of each entity that has agreed to waive a
    portion of its fee. Absent such fee waivers, management/advisory fees would
    be: Large Cap Value Portfolio, .70%; Large Cap Growth Portfolio, .75%;
    Small Cap Value Portfolio, 1.00%; Small Cap Growth Portfolio, 1.00%; Mid-
    Cap Growth Portfolio, .95%; Capital Appreciation Portfolio, .75%; Equity
    Income Portfolio, .75%; and Balanced Portfolio, .75%.
(2) The 12b-1 fees shown include the Large Cap Value, Large Cap Growth, Small
    Cap Value, Small Cap Growth, Mid-Cap Growth, Capital Appreciation, Equity
    Income and Balanced Portfolios' current 12b-1 budget. The maximum 12b-1
    fees payable by Class B shares of these Portfolios are .60%.
(3) Other Expenses for the Large Cap Growth and Small Cap Value Portfolios are
    based on estimated amounts for the current fiscal year.
(4) Absent the voluntary fee waivers described above, total operating expenses
    for the Class B Shares of the Portfolios would be: Large Cap Value

INVESTMENT 
OBJECTIVES AND 
POLICIES _______________________________________________________________________
 
LARGE CAP VALUE   The investment objective of the Large Cap Value Portfolio is
PORTFOLIO         long-term growth of capital and income. There is no
                  assurance that the Portfolio will achieve its investment
                  objective.
                     The Portfolio invests primarily in a diversified
                  portfolio of high quality, income producing common stocks
                  which, in the advisers' opinion, are undervalued in the
                  marketplace at the time of purchase. In general, the
                  advisers characterize high quality securities as those that
                  have above-average returns-on-equity and above average
                  reinvestment rates relative to the stock market in general
                  as measured by the S&P Barra/Value Index. The advisers also
                  consider other factors, such as earnings and dividend growth
                  prospects as well as industry outlook and market share.
                  Under normal conditions, the Portfolio will invest at least
                  65% of its total assets in common stocks of companies with a
                  market capitalization of at least $1 billion.
                     Under normal circumstances the Portfolio, to the extent
                  not invested in the securities described above, may invest
                  in investment grade bonds. Investment grade bonds include
                  securities rated BBB by Standard & Poor's Corporation (S&P")
                  or Baa by Moody's Investors Service, Inc. (Moody's), which
                  may be regarded as having speculative characteristics.
                     The Portfolio's investment adviser is SEI Financial
                  Management Corporation and its investment sub-advisers are
                  LSV Asset Management, Mellon Equity Associates and Merus
                  Capital Management.
 
LARGE CAP         The investment objective of the Large Cap Growth Portfolio
GROWTH            is capital appreciation. There is no assurance that the
PORTFOLIO         Portfolio will achieve its investment objective.
                     Under normal conditions, the Portfolio will invest at
                  least 65% of its total assets in equity securities of large
                  companies (i.e., companies with market capitalizations of
                  more than $1 billion). The Portfolio's advisers will
                  generally select securities of issuers believed to possess
                  significant growth potential. Any remaining assets may be
                  invested in fixed income securities or in equity securities
                  of smaller companies that the Portfolio's advisers

                  advisory fee. The Large Cap Growth and Small Cap Value
                  Portfolios had not commenced operations as of the fiscal
                  year ended September 30, 1994.
 
SUNBANK CAPITAL   SunBank Capital Management, N.A. ("SunBank") serves as
MANAGEMENT,       investment adviser for the Capital Appreciation, Balanced
N.A.              and Capital Growth Portfolios. SunBank was established in
                  1934 and is owned by SunBank, Inc., a wholly-owned
                  subsidiary of Sun Trust Banks, Inc., a bank holding company.
                  As of September 30, 1994, SunBank had discretionary
                  management authority with respect to approximately $11.75
                  billion of assets. The principal business address of SunBank
                  is P.O. Box 3808, Orlando, Florida 32802,
                     Anthony R. Gray is Chairman and Chief Investment Officer
                  of SunBank since 1987, and has managed the Capital
                  Appreciation and Balanced Portfolios since their inception.
                  Mr. Gray joined SunBank in 1979 as Director of Research of
                  the Trust Investment Division.
                     John D. Race is President of SunBank and has managed the
                  Balanced Portfolio since its inception.
                     Thomas Edgar is Senior Vice President of SunBank since
                  1990, and has managed the Capital Growth Portfolio since its
                  inception. Prior to joining SunBank, Mr. Edgar served as
                  Senior Vice President of First Union Bank from 1988 to 1990.
                     SunBank is entitled to a fee, which is calculated daily
                  and paid monthly, at an annual rate of .25% of the Capital
                  Appreciation and Balanced Portfolios' average daily net
                  assets. For the fiscal year ended September 30, 1994, each
                  Portfolio paid SunBank an advisory fee of .25% of its
                  average daily net assets. SunBank is not paid a fee for
                  providing advisory services to the Capital Growth Portfolio.
 
DISTRIBUTION ___________________________________________________________________

                  SEI Financial Services Company (the "Distributor"), a
                  wholly-owned subsidiary of SEI, serves as each Portfolio's
                  distributor pursuant to a distribution agreement (the
                  "Distribution Agreement") with the Trust. Each Portfolio has
                  a distribution plan for its shares (the "Class A Plan,"
                  "Class B Plan" and/or the "ProVantage Plan;" collectively,
                  the "Plans") pursuant to Rule 12b-1 under 1940 Act. The
                  Trust intends to operate the Plans in accordance with their
                  terms and with the NASD rules concerning sales charges.
                     The Distribution Agreement and the Plans provide for
                  reimbursement for expenses incurred by the Distributor in an
                  amount not to exceed .30% of the average daily net assets of
                  each Portfolio on an annualized basis, provided those
                  expenses are permissible as to both type and amount under a
                  budget adopted by the Board of Trustees, including those
                  Trustees who are not interested persons and have no
                  financial interest in the Plans or any related agreement
                  ("Qualified Trustees"). The Class B and ProVantage Plans
                  also provide for additional payments for distribution and
                  shareholder services as described below.
 
<PAGE>
 
                     Distribution-related expenses reimbursable to the
                  Distributor under the budget include those related to the
                  costs of advertising and sales materials, the costs of
                  federal and state securities law registration, advertising
                  expenses and promotional and sales expenses including
                  expenses for travel, communication and compensation and
                  benefits for sales personnel. The Trust is not obligated to
                  reimburse the Distributor for any expenditures in excess of
                  the approved budget. Currently the budget (shown here as a
                  percentage of daily net assets) for each Portfolio is as
                  follows: Large Cap Value Portfolio, 0.05%; Large Cap Growth
                  Portfolio, 0.07%; Small Cap Value Portfolio, 0.07%, Small
                  Cap Growth Portfolio, 0.06%; Mid-Cap Growth Portfolio,
                  0.08%; Capital Appreciation Portfolio, 0.05%; Equity Income
                  Portfolio, 0.06%; Balanced Portfolio, 0.11%; and Real Estate
                  Securities Portfolio, 0.06%. SFM has voluntarily agreed to
                  waive its fee and to reimburse the Capital Growth Portfolio
                  for its expenses in order to limit the operating expenses of
                  the Portfolio to not more than 0.00% on an annualized basis.
                  Distribution expenses not attributable to a specific
                  portfolio are allocated among each of the portfolios of the
                  Trust based on average net assets.
                     The Class B Plan, in addition to providing for the
                  reimbursement payments described above, provides for
                  payments to the Distributor at an annual rate of .30% of the
                  Portfolio's average daily net assets attributable to Class B
                  shares. These additional payments are characterized as
                  "compensation," and are not directly tied to expenses
                  incurred by the Distributor; the payments the Distributor
                  receives during any year may therefore be higher or lower
                  than its actual expenses. This additional payment may be
                  used to compensate financial institutions that provide
                  distribution-related services to their customers.
                     The ProVantage Plan is similar to the Class B Plan
                  described above, but applies only to ProVantage Funds
                  shareholders.
                     It is possible that an institution may offer different
                  classes of shares to its customers and thus receive
                  different compensation with respect to different classes.
                  These financial institutions may also charge separate fees
                  to their customers.
                     The Trust may also execute brokerage or other agency
                  transactions through the Distributor for which the
                  Distributor may receive usual and customary compensation.
                     In addition, the Distributor may, from time to time in
                  its sole discretion, institute one or more promotional
                  incentive programs, which will be paid by the Distributor
                  from the sales charge it receives or from any other source
                  available to it. Under any such program, the Distributor
                  will provide promotional incentives, in the form of cash or
                  other compensation, including merchandise, airline vouchers,
                  trips and vacation packages, to all dealers selling shares
                  of the Portfolios. Such promotional incentives will be
                  offered uniformly to all dealers and predicated upon the
                  amount of shares of the Portfolios sold by the dealer.

PURCHASE AND REDEMPTION OF SHARES ______________________________________________

                  Financial institutions may acquire Class A and/or Class B
                  shares of the Portfolios for their own accounts or as record
                  owner on behalf of fiduciary, agency or custody accounts by
                  placing orders with SFM. Institutions that use certain SEI
                  proprietary systems may place orders electronically through
                  those systems. State securities laws may require banks and
                  financial institutions purchasing shares for their customers
                  to register as dealers pursuant to state laws. Financial
                  institutions may impose an earlier cut-off time for receipt
                  of purchase orders directed through them to allow for
                  processing and transmittal of these orders to SFM for
                  effectiveness the same day. Financial institutions that
                  purchase shares for the accounts of their customers may
                  impose separate charges on these customers for account
                  services. Shares of the Portfolios are offered only to
                  residents of states in which the shares are eligible for
                  purchase.
                     Shares of each Portfolio may be purchased or redeemed on
                  days on which the New York Stock Exchange is open for
                  business ("Business Days").
                     Shareholders who desire to purchase shares for cash must
                  place their orders with SFM 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
                  the Portfolios calculated to three decimal places. The Trust
                  will send shareholders a statement of shares owned after
                  each transaction. The purchase price of shares is the net
                  asset value next determined after a purchase order is
                  received and accepted by the Trust. The net asset value per
                  share of each Portfolio is determined by dividing the total
                  market value of a Portfolio's investment and other assets,
                  less any liabilities, by the total outstanding shares of
                  that Portfolio. Net asset value per share is determined
                  daily as of 4:00 p.m. Eastern time on any Business Day.
                     The market value of each portfolio security is obtained
                  by SFM from an independent pricing service. Securities
                  having maturities of 60 days or less at the time of purchase
                  will be valued using the amortized cost method (described in
                  the Statement of Additional Information). 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.
                     Shareholders who desire to redeem shares of the
                  Portfolios must place their redemption orders with SFM prior
                  to 4:00 p.m. Eastern time on any Business Day. The
 
<PAGE>
 
                  redemption price is the net asset value per share of the
                  Portfolio next determined after receipt by SFM of the
                  redemption order. Payment on redemption will be made as
                  promptly as possible and, in any event, within seven days
                  after the redemption order is received.
                     Purchase and redemption orders may be placed by
                  telephone. Neither the Trust nor SFM 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 SFM 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 Portfolio 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 Portfolio refers to the income
                  generated by a hypothetical investment, net of any sales
                  charge imposed in the case of some of the ProVantage Funds
                  shares, in such Portfolio over a thirty day period. This
                  income is then "annualized," i.e., the income over thirty
                  days is assumed to be generated over one year and is shown
                  as a percentage of the investment.
                     The total return of a Portfolio 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.
                     The performance of Class A shares will normally be higher
                  than for Class B shares and ProVantage Fund shares because
                  of the additional distribution expenses charged to Class B
                  shares and additional distribution expenses, transfer agency
                  expenses and sales charges (when applicable) charged to
                  ProVantage Funds shares.
                     A Portfolio may periodically compare its performance to
                  that of other mutual funds tracked by mutual fund rating
                  services (such as Lipper Analytical) or by financial and
                  business publications and periodicals, broad groups of
                  comparable mutual funds, unmanaged indices which may assume
                  investment of dividends but generally do not reflect
                  deductions for administrative and management costs or to
                  other investment alternatives. A Portfolio may quote
                  Morningstar, Inc., a service that ranks mutual funds on the
                  basis of risk-adjusted performance. A Portfolio may use
                  long-term performance of these capital markets to
                  demonstrate general long-term risk versus reward scenarios
                  and could include the value of a hypothetical investment in
                  any of the capital markets. A Portfolio may also

SEI Institutional Managed Trust (the "Trust") is a mutual fund that offers
shareholders a convenient means of investing their funds in one or more
professionally managed diversified and non-diversified portfolios of
securities. The Large Cap Value, Large Cap Growth, Small Cap Value, Small Cap
Growth, Mid-Cap Growth, Capital Appreciation, Equity Income and Balanced
Portfolios, investment portfolios of the Trust, offer three classes of shares,
Class A shares, Class B shares and ProVantage Funds shares. ProVantage Funds
shares differ from Class A and Class B shares primarily in the imposition of
sales charges and the allocation of certain distribution expenses and transfer
agent fees. ProVantage Funds shares are available through SEI Financial
Services Company (the Trust's distributor) and through participating broker-
dealers, financial institutions and other organizations. This Prospectus offers
the ProVantage Funds shares of one balanced (fixed income and equity) and seven
equity portfolios (the "Portfolios" and each of these a "Portfolio") listed
above.

(1) A charge, currently $10.00, is imposed on wires of redemption proceeds of
    the Portfolios' ProVantage Funds shares.
(2) SEI Financial Management Corporation ("SFM"), in its capacity as Manager
    for each Portfolio, and certain of the investment advisers and sub-advisers
    (collectively, "advisers") have agreed to waive, on a voluntary basis, a
    portion of their fees, and the management/advisory fees shown reflect this
    voluntary waiver. Such fee waivers are voluntary and may be terminated at
    any time in the sole discretion of each entity that has agreed to waive a
    portion of its fee. Absent such fee waiver, management/advisory fees would
    be: Large Cap Value Portfolio, .70%; Large Cap Growth Portfolio, .75%;
    Small Cap Value Portfolio, 1.00%; Small Cap Growth Portfolio, 1.00%; Mid-
    Cap Growth Portfolio, .95%; Capital Appreciation Portfolio, .75%; Equity
    Income Portfolio, .75%; and Balanced Portfolio, .75%;.
(3) The 12b-1 fees shown include both the Portfolios' current 12b-1 budget for
    reimbursement of expenses and the Distributor's voluntary waiver of a
    portion of its compensatory fee. The Distributor reserves the right to
    terminate its waiver at any time in its sole discretion. The maximum 12b-1
    fees payable by the ProVantage Funds shares of each Portfolio are .60%.
(4) Other Expenses for the Large Cap Growth and Small Cap Value Portfolios are
    based on estimated amounts for the current fiscal year.
(5) Absent the voluntary fee waivers described above, total operating expenses
    for ProVantage Funds shares would be: Large Cap Value Portfolio, 1.20%;
    Large Cap Growth Portfolio, 1.35%; Small Cap Value Portfolio, 1.57%; Small
    Cap Growth Portfolio, 1.51%; Mid-Cap Growth Portfolio 1.46%; Capital
    Appreciation Portfolio, 1.24%; Equity Income Portfolio, 1.24%; and Balanced
    Portfolio, 1.31%.

THE EXAMPLE SHOULD NOT BE CONSIDERED A REPRESENTATION OF PAST OR FUTURE
EXPENSES. ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN.
 
The purpose of the expense table and example is to assist the investor in
understanding the various costs and expenses that may be directly or indirectly
borne by investors in ProVantage Funds shares of each Portfolio. A person who
purchases shares through an account with a financial institution may be charged
separate fees by that institution. The information set forth in the foregoing
table and example relates only to the ProVantage Funds shares. Each Portfolio
also offers Class A and Class B shares, which are subject to the same expenses,
except that there are no sales loads, different distribution costs and no
transfer agent costs. Additional information may be found under "The Manager
and Shareholder Servicing Agent," "The Advisers and Sub-Advisers" and
"Distribution."
 
The rules of the Securities and Exchange Commission require that the maximum
sales charge be reflected in the above table. However, certain investors may
qualify for reduced sales charges. See "Purchase of Shares." Long-term
shareholders may pay more than the economic equivalent of the maximum front-end
sales charges otherwise permitted by the Rules of Fair Practice (the "Rules")
of the National Association of Securities Dealers, Inc. ("NASD").

                     John D. Race is President of SunBank and has managed the
                  Balanced Portfolio since its inception.
                     SunBank is entitled to a fee, which is calculated daily
                  and paid monthly, at an annual rate of .25% of the Capital
                  Appreciation and Balanced Portfolios' average daily net
                  assets. For the fiscal year ended September 30, 1994, each
                  Portfolio paid SunBank an advisory fee of .25% of its
                  average daily net assets.
 
DISTRIBUTION ___________________________________________________________________

                  SEI Financial Services Company (the "Distributor"), a
                  wholly-owned subsidiary of SEI, serves as each Portfolio's
                  distributor pursuant to a distribution agreement (the
                  "Distribution Agreement") with the Trust. Each Portfolio has
                  a distribution plan for its shares (the "Class A Plan,"
                  "Class B Plan" and the "ProVantage Plan;" collectively, "the
                  Plans") pursuant to Rule 12b-1 under the 1940 Act. The Trust
                  intends to operate the Plans in accordance with their terms
                  and with the NASD rules concerning sales charges.
                     The Distribution Agreement and the Plans provide for
                  reimbursement for expenses incurred by the Distributor in an
                  amount not to exceed .30% of the average daily net assets of
                  each Portfolio on an annualized basis, provided those
                  expenses are permissible as to both type and amount under a
                  budget, adopted by the Board of Trustees, including those
                  Trustees who are not interested persons and have no
                  financial interest in the Plans or any related agreement
                  ("Qualified Trustees"). The Class B and ProVantage Plans
                  provide for additional payments for distribution and
                  shareholder services as described below.
                     Distribution-related expenses reimbursable to the
                  Distributor under the budget include those related to the
                  costs of advertising and sales materials, the costs of
                  federal and state securities law registration, advertising
                  expenses and promotional and sales expenses including
                  expenses for travel, communication and compensation and
                  benefits for sales personnel. The Trust is not obligated to
                  reimburse the Distributor for any expenditures in excess of
                  the approved budget. Currently the budget (shown here as a
                  percentage of daily net assets) for each Portfolio is as
                  follows: Large Cap Value Portfolio, .05%; Large Cap Growth
                  Portfolio, .07%; Small Cap Value Portfolio, .07%; Small Cap
                  Growth Portfolio, .06%; Mid-Cap Growth Portfolio, .08%;
                  Capital Appreciation Portfolio, .05%; Equity Income
                  Portfolio, .06%; and Balanced Portfolio, .11%. Distribution
                  expenses not attributable to a specific portfolio are
                  allocated among each of the portfolios of the Trust based on
                  average net assets.
                     The ProVantage Plan, in addition to providing for the
                  reimbursement payments described above, provides for
                  payments to the Distributor at an annual rate of .30% of the
                  Portfolio's average daily net assets attributable to
                  ProVantage Funds shares. This additional payment may be used
                  to compensate financial institutions that provide
                  distribution-related services to their customers. These
                  additional payments are characterized as "compensation," and
                  are not directly tied to expenses incurred by the
                  Distributor; the payments the Distributor receives during
                  any year may therefore be higher or lower than its actual
                  expenses.
 
<PAGE>

                     These additional payments may be used to compensate the
                  Distributor for its services in connection with distribution
                  assistance or provision of shareholder services, and some or
                  all of it may be used to pay financial institutions and
                  intermediaries such as banks, savings and loan associations,
                  insurance companies, and investment counselors, broker-
                  dealers and the Distributor's affiliates and subsidiaries
                  for services or reimbursement of expenses incurred in
                  connection with distribution assistance or provision of
                  shareholder services. If the Distributor's expenses are less
                  than its fees under the ProVantage Plan, the Trust will
                  still pay the full fee and the Distributor will realize a
                  profit, but the Trust will not be obligated to pay in excess
                  of the full fee, even if the Distributor's actual expenses
                  are higher. Currently the Distributor is taking this
                  additional compensation payment under the ProVantage Plan at
                  a rate of only .25% of each Portfolio's average daily net
                  assets, on an annualized basis, attributable to ProVantage
                  Funds shares.
                     The Class B Plan is similar to the ProVantage Plan
                  described above except that for each Portfolio, the Class B
                  Plan provides for additional payments to the Distributor of
                  .30% and it applies only to Class B shares. It is possible
                  that an institution may offer different classes of shares to
                  its customers and thus receive different compensation with
                  respect to different classes. These financial institutions
                  may also charge separate fees to their customers.
                     The Trust may also execute brokerage or other agency
                  transactions through the Distributor for which the
                  Distributor may receive usual and customary compensation.
                     In addition, the Distributor may, from time to time in
                  its sole discretion, institute one or more promotional
                  incentive programs, which will be paid by the Distributor
                  from the sales charge it receives or from any other source
                  available to it. Under any such program, the Distributor
                  will provide promotional incentives, in the form of cash or
                  other compensation, including merchandise, airline vouchers,
                  trips and vacation packages, to all dealers selling shares
                  of the Portfolios. Such promotional incentives will be
                  offered uniformly to all dealers and predicated upon the
                  amount of shares of the Portfolios sold by the dealer.
 
PERFORMANCE ____________________________________________________________________

                  From time to time, a Portfolio 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 Portfolio refers to the income
                  generated by a hypothetical investment, net of any sales
                  charge imposed in the case of some of the ProVantage Funds
                  shares, in such Portfolio over a thirty day period. This
                  income is then "annualized," i.e., the income over thirty
                  days is assumed to be generated over one year and is shown
                  as a percentage of the investment.
                     The total return of a Portfolio 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.

                     Dividends and capital gains of each Portfolio 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.
                     The dividends on ProVantage Funds shares will normally be
                  lower than on Class A and Class B shares of a Portfolio
                  because of the additional distribution and transfer agent
                  expenses charged to ProVantage Funds shares.

DESCRIPTION OF 
PERMITTED 
INVESTMENTS AND 
RISK FACTORS ___________________________________________________________________

                  The following is a description of the permitted investment
                  practices for the Portfolios, and the associated risk
                  factors:

American          ADRs are securities, typically issued by U.S. financial
Depositary        institution (a "depositary"), that evidence ownership
Receipts          interests in a security or a pool of securities issued by a
("ADRs")          foreign issuer and deposited with the depositary. ADRs may
                  be available 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 underlying security.
                     Holders of unsponsored depositary receipts 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. ADRs that are not listed or traded on
                  an exchange can be purchased over the counter. Prices for
                  such ADRs are determined by the market makers. The Large Cap
                  Growth and Small Cap Value Portfolios may invest in ADRs.

Bankers'          Bankers' acceptances are bills of exchange or time drafts
Acceptances       drawn on and accepted by a commercial bank. Bankers'
                  acceptances are used by corporations to finance the shipment
                  and storage of goods. Maturities are generally six months or
                  less. All Portfolios may invest in bankers' acceptances.

Certificates of   Certificates of deposit are interest bearing instruments
Deposit           with a specific maturity. They are issued by banks and
                  savings and loan institutions in exchange for the deposit of
                  funds and

     Ms. Krauss then reported that the recently effective new prospectus for the
SEI Institutional Managed Trust discloses that, subject to regulatory approvals,
the Trust will issue new Class B Units which will have the type of distribution
plan described above. Accordingly, she requested Board approval in order to
adopt such a plan with respect to Class B Units of this Trust. Whereupon, upon

                        direct expenses and provides that payments be made to
                        unitholders which provide administrative services.

                        outstanding units of beneficial interest of Class B of
