                           IMPORTANT INFORMATION FOR
                   KEMPER SHORT-INTERMEDIATE GOVERNMENT FUND
 
YOUR FUND WILL HOST A JOINT SPECIAL MEETING OF SHAREHOLDERS ON WEDNESDAY,
DECEMBER 16, 1998, IN BOSTON, MASSACHUSETTS. THE PURPOSE IS TO VOTE ON CERTAIN
IMPORTANT PROPOSALS AFFECTING YOUR FUND.
 
THE FIRST FEW PAGES OF THIS BOOKLET SUMMARIZE THE PROPOSALS AND EXPLAIN THE
PROXY PROCESS -- INCLUDING HOW TO CAST YOUR VOTES. BEFORE YOU VOTE, PLEASE READ
THE FULL TEXT OF THE PROXY STATEMENT FOR A COMPLETE UNDERSTANDING OF THE
PROPOSALS.
 
Q.  WHAT ARE SHAREHOLDERS BEING ASKED TO VOTE ON AT THE UPCOMING SPECIAL
    SHAREHOLDER MEETING ON DECEMBER 16, 1998?
 
A.  The Board of Trustees for the Kemper Short-Intermediate Government Fund (the
    "Short-Intermediate Fund") has called a Special Shareholder Meeting for
    December 16, 1998 at which you will be asked to vote on the approval of a
    new investment management agreement and a reorganization (the
    "Reorganization") of your fund into the Kemper Adjustable Rate U.S.
    Government Fund (the "Adjustable Rate Fund"). As part of the Reorganization,
    Adjustable Rate Fund shareholders will be asked to vote on a new investment
    objective and revisions to certain investment policies. The Adjustable Rate
    Fund would then be renamed as the Kemper Short-Term U.S. Government Fund
    (the "Combined Fund"). Consummation of the Reorganization is contingent upon
    the approval of shareholders of the Adjustable Rate Fund of a new investment
    objective and policies.
 
Q.  ARE THERE ANY DIFFERENCES BETWEEN THE FUNDS?
 
A.  The Short-Intermediate Fund seeks, with equal emphasis, high current income
    and preservation of capital from a portfolio composed primarily of short and
    intermediate-term U.S. Government securities. The Adjustable Rate Fund
    currently seeks high current income consistent with low volatility of
    principal from a portfolio composed primarily of adjustable rate U.S.
    Government securities. The Combined Fund will seek high current income and
    preservation of capital from a portfolio composed primarily of short-term
    U.S. Government securities and have a target maturity of less than three
    years.
 
Q.  WHAT ADVANTAGES WILL THE REORGANIZATION PRODUCE FOR FUND SHAREHOLDERS?
 
A.  We expect the proposed Reorganization to (i) lower operating expenses as a
    percentage of net assets due to the Combined Fund's larger net assets and
    greater economies of scale; (ii) reduce interest rate risk as the Combined
    Fund will have a maturity range of 1-3 years versus a maturity of 2-5 years
    for the Short-Intermediate Fund, and (iii) potentially increase income and
    total return potential as the Combined Fund will have the ability to invest
    a portion of its assets in lower quality non-U.S. Government securities.
 
Q.  WHAT IS THE TIMETABLE FOR THE REORGANIZATION?
 
A.  The Joint Special Meeting is scheduled for December 16, 1998. Shareholders
    of record as of September 22, 1998 will be eligible to vote their shares at
    the Joint Special Meeting. If approved, the Reorganization is expected to
    close as soon as practicable after the Joint Special Meeting of
    Shareholders.
 
Q.  WILL I RECEIVE NEW SHARES IN EXCHANGE FOR MY CURRENT SHARES?
 
A.  Yes. Upon approval and completion of the Reorganization, shareholders of the
    Short-Intermediate Fund will exchange their shares for shares of the
    Adjustable Rate Fund based upon a specified exchange ratio determined by the
    ratio of the respective net asset values of the funds. You will receive
    Adjustable Rate Fund shares whose aggregate value at the time of issuance
    will equal the aggregate value of your Short-Intermediate Fund shares on
    that date.
<PAGE>   4
 
Q.  IF I OWN SHARES IN CERTIFICATE FORM, WILL I NEED TO EXCHANGE THEM FOR
    CERTIFICATES OF MY NEW FUND?
 
A.  Certificates for Adjustable Rate Fund shares will not be issued
    automatically as part of the Reorganization, although we will send you
    certificates upon request. If you currently own Short-Intermediate Fund
    shares in certificate form, you will need to return these certificates to
    Kemper in order to receive new certificates for your Adjustable Rate Fund
    shares.
 
    If you prefer, however, you may exchange your certificates for book entry
    shares. These shares are held in a convenient computerized system that
    enables shareholders to receive a complete and accurate record of their
    holdings without having to worry about the safekeeping of certificates or
    the expense involved with replacing a lost or stolen certificate.
 
    Regardless of the way you choose to hold your shares after the
    Reorganization, certificates should be returned to the fund's shareholder
    service agent by certified mail as soon as possible.
 
Q.  WILL I HAVE TO PAY ANY FEES OR EXPENSES IN CONNECTION WITH THE
    REORGANIZATION?
 
A.  No. The expenses associated with the Reorganization will be borne by Scudder
    Kemper Investments, Inc., the investment adviser for the Funds.
 
Q.  HOW DO MANAGEMENT FEES AND OTHER FUND OPERATING EXPENSES COMPARE BETWEEN THE
    TWO FUNDS?
 
A.  The investment management fee schedules for the funds are the same. Fund
    management expects that the overall expenses, as a percentage of net assets,
    will decrease reflecting the larger net assets and greater economies of
    scale of the Combined Fund.
 
Q.  WILL THIS REORGANIZATION CREATE A TAXABLE EVENT FOR ME?
 
A.  The Reorganization is intended to be done on a tax-free basis for federal
    income tax purposes. Therefore, you will recognize no gain or loss for
    federal income tax purposes as a result of the Reorganization. In addition,
    the tax basis and holding period of the Adjustable Rate Fund shares you
    receive will be the same as the tax basis and holding period of your
    Short-Intermediate Fund shares.
 
Q.  CAN I EXCHANGE OR REDEEM MY SHORT-INTERMEDIATE FUND SHARES BEFORE THE
    REORGANIZATION TAKES PLACE?
 
A.  You may exchange your Short-Intermediate Fund shares for shares of any other
    Kemper Fund, or redeem your shares, at any time. If you choose to do so,
    your request will be treated as a normal exchange or redemption of shares
    (subject to any applicable deferred sales charge) and will be a taxable
    transaction for federal income tax purposes.
 
Q.  WHAT ELSE WILL I BE VOTING ON?
 
A.  You will also be asked to vote on the approval of a new investment
    management agreement.
 
Q.  WHY AM I BEING ASKED TO VOTE ON A NEW INVESTMENT MANAGEMENT AGREEMENT?
 
A.  Zurich Insurance Company ("Zurich"), which is the majority owner of your
    Fund's adviser, Scudder Kemper Investments, Inc. ("Scudder Kemper"), has
    combined its businesses with the financial services businesses of B.A.T.
    Industries p.l.c. ("B.A.T"). The resulting company, Zurich Financial
    Services ("Zurich Financial Services"), has become Zurich's parent company.
    Although this transaction will not affect the operations of Scudder Kemper
    or your Fund, we are asking the Fund's shareholders to approve a new
    investment management agreement to assure that there is no interruption in
    the services Scudder Kemper provides to your Fund.
 
    As a result of the Zurich-B.A.T transaction, the former shareholders of
    B.A.T indirectly own a 43% interest in Zurich through a new holding company,
    Allied Zurich p.l.c. This change in ownership of Zurich may be deemed to
    have caused a "change in control" of Scudder Kemper, even though Scudder
    Kemper's operations will not change as a result. The Investment Company Act
    of 1940, which regulates investment companies such as your Fund, requires
    that fund shareholders approve a new investment management agreement
    whenever there is a change in control of a fund's adviser (even in the most
    technical, definitional sense). Pursuant to an exemptive order issued by the
<PAGE>   5
 
    Securities and Exchange Commission, your Fund entered into a new investment
    management agreement, subject to receipt of shareholder approval within 150
    days. Accordingly, we are seeking shareholder approval of the new investment
    management agreement with your Fund.
 
Q.  HOW WILL THE ZURICH-B.A.T TRANSACTION AFFECT ME AS A FUND SHAREHOLDER?
 
A.  We do not expect the transaction to affect you as a Fund shareholder. The
    new investment management agreement is identical to the former investment
    management agreement, except for the dates of execution and termination.
    Similarly, the other service arrangements between your Fund and Scudder
    Kemper or affiliates of Scudder Kemper will not be affected. If shareholders
    do not approve the new investment management agreement, the agreement will
    terminate and the Board Members of your Fund will take such action as they
    deem to be in the best interests of your Fund and its shareholders.
 
Q.  HAS THE FUND'S BOARD OF TRUSTEES APPROVED THE PROPOSAL?
 
A.  The Board of Trustees for the Short-Intermediate Fund has unanimously agreed
    that the new investment management agreement and the Reorganization are in
    your best interests and recommends that you vote in favor of them.
 
Q.  HOW DO I VOTE MY SHARES?
 
A.  You can vote your shares by completing and signing the enclosed proxy
    card(s), and mailing them in the enclosed postage-paid envelope. If you need
    any assistance, or have any questions regarding the proposals or how to vote
    your shares, please call your financial adviser or Kemper at (800)    -
     weekdays from 7:00 a.m. to 7:00 p.m. Central time.
 
Q.  WILL KEMPER CONTACT ME?
 
A.  You may receive a call to verify that you received your proxy materials and
    to answer any questions you may have about the Reorganization.
 
    THE BOARD MEMBERS OF YOUR FUND, INCLUDING THOSE WHO ARE NOT AFFILIATED WITH
    THE FUND, SCUDDER KEMPER OR ZURICH, RECOMMEND THAT YOU VOTE FOR APPROVAL OF
    THE REORGANIZATION AND FOR APPROVAL OF THE NEW INVESTMENT MANAGEMENT
    AGREEMENT.

Q.  WHAT ARE SHAREHOLDERS BEING ASKED TO VOTE ON AT THE UPCOMING SPECIAL
    SHAREHOLDER MEETING ON DECEMBER 16, 1998?
 
A.  The Board of Trustees for the Kemper Adjustable Rate U.S. Government Fund
    (the "Adjustable Rate Fund") has called a Special Shareholder Meeting for
    December 16, 1998 at which you will be asked to vote on the approval of a
    new investment management agreement and, in connection with a reorganization
    of the Kemper Short-Intermediate Government Fund (the "Short-Intermediate

Q.  WHAT IS HAPPENING WITH THE REORGANIZATION?
 
A.  The Board of Trustees for the Short-Intermediate Fund has called a Special
    Shareholder Meeting for December 16, 1998 at which its shareholders will be
    asked to vote on the approval of a new investment management agreement and a
    reorganization (the "Reorganization") of the Short-Intermediate Fund into
    the Adjustable Rate Fund. Consummation of the Reorganization is contingent
    upon shareholders of the Adjustable Rate Fund approving changes to its
    investment objective and policies. As a part of these changes, the
    Adjustable Rate Fund would be renamed as the Kemper Short-Term U.S.
    Government Fund (the "Combined Fund").
<PAGE>   7
 
Q.  WHAT ADVANTAGES WILL THE REORGANIZATION PRODUCE FOR FUND SHAREHOLDERS?
 
A.  We expect the proposed Reorganization to lower operating expenses as a
    percentage of net assets due to the Combined Fund's larger net assets and
    greater economies of scale.
 
Q.  WHAT IS THE TIMETABLE FOR THE REORGANIZATION?
 
A.  The Joint Special Meeting of Shareholders is scheduled for December 16,
    1998. Shareholders of record as of September 22, 1998 will be eligible to
    vote their shares at the Joint Special Meeting. If approved, the
    Reorganization is expected to close as soon as practicable after the Joint
    Special Meeting of Shareholders.
 
Q.  WILL I HAVE TO PAY ANY FEES OR EXPENSES IN CONNECTION WITH THE
    REORGANIZATION?
 
A.  No. The expenses associated with the Reorganization will be borne by Scudder
    Kemper Investments, Inc., the investment adviser for the Funds.
 
Q.  WHAT ARE THE PROPOSED NEW INVESTMENT OBJECTIVES AND POLICIES?
 
A.  In connection with the Reorganization, you are being asked to approve a new
    investment objective and policies that will give the Adjustable Rate Fund
    greater flexibility to invest in fixed rate U.S. government securities and,
    to a limited extent, in other lower quality non-U.S. government securities.
    The Adjustable Rate Fund's new investment objective will be to seek high
    current income and preservation of capital.
 
Q.  WHAT ADVANTAGES WILL THE CHANGING OF THE INVESTMENT OBJECTIVE AND POLICIES
    PRODUCE FOR FUND SHAREHOLDERS?
 
A.  The new investment policies of the Adjustable Rate Fund would provide more
    diversification of investment choice and give the Adviser greater
    flexibility to invest in short-term fixed income U.S. Government securities
    and, to a limited extent, in lower quality non-U.S. Government securities.
    While this change in approach may result in more volatility of principal,
    the Adviser believes that the greater flexibility to invest in lower quality
    non-U.S. Government securities could potentially increase income and total
    return.
 
Q.  HAS THE FUND'S BOARD OF TRUSTEES APPROVED THE PROPOSALS?
 
A.  The Board of Trustees for the Adjustable Rate Fund has unanimously agreed
    that the new investment management agreement and the new investment
    objective and policies are in your best interests and recommends that you

PROSPECTUS/PROXY STATEMENT
 
KEMPER ADJUSTABLE RATE U.S. GOVERNMENT FUND
 
RELATING TO THE ACQUISITION OF ASSETS AND LIABILITIES OF
KEMPER SHORT-INTERMEDIATE GOVERNMENT FUND
 
This Prospectus/Proxy Statement is being furnished to shareholders of the Kemper
Short-Intermediate Government Fund (the "Short-Intermediate Fund" or a "Fund"),
a series of the Kemper Portfolios (the "Trust"), a Massachusetts business trust,
and the shareholders of the Kemper Adjustable Rate U.S. Government Fund, an
open-end management investment company organized as a Massachusetts business
trust (the "Adjustable Rate Fund" which may also sometimes be referred to as a
"Fund" or a "Trust") and relates to the special meeting of shareholders of the
Funds to be held at the offices of Scudder Kemper Investments, Inc., 13th Floor,
Two International Place in Boston, Massachusetts on Wednesday, December 16, 1998
at 10:00 a.m., Eastern Time and at any and all adjournments thereof (the
"Special Meeting"). Shareholders of record as of the close of business on
September 22, 1998 are entitled to vote at the Special Meeting or any
adjournment thereof. A primary purpose of the Special Meeting is to approve or
disapprove the proposed reorganization of the Short-Intermediate Fund into the
Adjustable Rate Fund (the "Reorganization"). The Reorganization would result in
shareholders of the Short-Intermediate Fund in effect exchanging their Class A,
B and C shares of the Short-Intermediate Fund for corresponding Class A, B and C
shares of the Adjustable Rate Fund. The purpose of the Reorganization is to
permit the shareholders of the Short-Intermediate Fund to (i) lower gross
operating expenses as a percentage of net assets due to the combined funds'
larger net assets and greater economies of scale; (ii) reduce interest rate risk
as the new fund will have a maturity range of 1-3 years versus a maturity of 2-5
years for the Short-Intermediate Fund, and (iii) potentially increase income and
total return as the new fund will have the ability to invest a portion of its
assets in lower quality non-U.S. Government securities.
 
At the Special Meeting, shareholders of both Funds will also vote on the
approval of a new investment management agreement created by consummation of the
B.A.T Transaction and shareholders of the Adjustable Rate Fund will vote on a
new investment objective and the revision of certain investment policies.
 
The investment objective of the Adjustable Rate Fund is to provide high current
income consistent with low volatility of principal. In connection with the
Reorganization, shareholders of the Adjustable Rate Fund will be asked to
approve a change in the Fund's investment objective. If approved, the new
investment objective of the Fund will be to seek high current income and
preservation of capital and the Fund will be renamed the Kemper Short-Term U.S.
Government Fund. There can be no assurance that the Adjustable Rate Fund will
achieve its investment objective. The address, principal executive office and
telephone number of the Funds is 222 South Riverside Plaza, Chicago, Illinois
60606, (312) 437-7000 or (800) 621-1048. The enclosed proxy and this
Prospectus/Proxy Statement are first being sent to shareholders of the funds on
or about                1998.

OFFENSE.
 
This Prospectus/Proxy Statement sets forth concisely the information
shareholders of the Short-Intermediate Fund should know before voting on the

Rate Fund) and constitutes an offering of Class A, B or C shares of beneficial
interest, of the Adjustable Rate Fund only. Please read it carefully and retain
it for future reference. A Statement of Additional Information dated

PROPOSAL 1. APPROVAL OF NEW INVESTMENT MANAGEMENT AGREEMENTS
 
THE BOARD RECOMMENDS THAT YOU VOTE "FOR" THE APPROVAL OF NEW INVESTMENT
MANAGEMENT AGREEMENTS.
 
INTRODUCTION.
 
Scudder Kemper Investments, Inc. acts as the Adviser to both Funds (the
"Adviser") pursuant to investment management agreements entered into by both
Funds and the Adviser. The investment management agreement in effect between
each Fund and the Adviser prior to the consummation of the transaction between
Zurich Insurance Company ("Zurich") and B.A.T Industries plc ("B.A.T") (the
"Zurich-B.A.T Transaction" or the "Transaction"), which is described below, is
referred to in this Proxy Statement as a "Former Investment Management
Agreement." The investment management agreement currently in effect between both
Funds and the Adviser was executed as of the consummation of the Zurich-B.A.T
Transaction and is referred to in this Proxy Statement as a "New Investment
Management Agreement," collectively, the "New Investment Management Agreements"
and, together with Former Investment Management Agreements, the "Investment
Management Agreements."
 
On June 26, 1997, one of the Adviser's predecessors, Scudder, Stevens & Clark,
Inc. ("Scudder"), entered into an agreement with Zurich pursuant to which
Scudder and Zurich agreed to form an alliance. On December 31, 1997, Zurich
acquired a majority interest in Scudder, and Zurich Kemper Investments, Inc.
("Kemper"), a Zurich subsidiary and Adviser of both Funds, became part of
Scudder. Scudder's name was changed to Scudder Kemper Investments, Inc. The
transaction between Scudder and Zurich (the "Scudder-Zurich Transaction")
resulted in the termination of each Fund's investment management agreement with
Kemper. However, the Former Investment Management Agreement between both Funds
and Scudder Kemper was approved by the Board of each Fund and by each Fund's
shareholders.
 
THE ZURICH-B.A.T TRANSACTION.
 
On December 22, 1997, Zurich and B.A.T entered into a definitive agreement (the
"Merger Agreement") pursuant to which businesses of Zurich (including Zurich's
almost 70% ownership interest in the Adviser) were to be combined with the
financial services businesses of B.A.T. On October 12, 1997, Zurich and B.A.T
had confirmed that they were engaged in discussions concerning a possible
business combination; on October 16, 1997, Zurich and B.A.T announced that they
had entered into an Agreement in Principle, dated as of October 15, 1997. The
Merger Agreement superseded the Agreement in Principle.
 
In order to effect this combination, Zurich and B.A.T first reorganized their
operations. Zurich became a subsidiary of a new Swiss holding company, Zurich
Allied AG, and Zurich shareholders became Zurich Allied AG shareholders. At the
same time, B.A.T separated its financial services business from its tobacco-
related businesses by spinning off to its shareholders a new British company,
Allied Zurich p.l.c., which now holds B.A.T's financial services businesses.
 
Zurich Allied AG then contributed its interest in Zurich, and Allied Zurich
p.l.c. contributed the B.A.T financial services businesses, to a jointly owned
company, Zurich Financial Services ("Zurich Financial Services"). As a result,
upon the completion of the Transaction, the former Zurich shareholders initially
became the owners (through Zurich Allied AG) of 57% of the voting stock of
Zurich Financial Services, and former B.A.T shareholders now own (through Allied
Zurich p.l.c.) 43% of the voting stock of Zurich Financial Services. Zurich
Financial Services now owns Zurich and the financial services businesses
previously owned by B.A.T.
 
CORPORATE GOVERNANCE.
 
At the closing of the Zurich-B.A.T Transaction, the parties entered into a
governing agreement that establishes the corporate governance structure for
Zurich Allied AG, Allied Zurich p.l.c. and Zurich Financial Services (the
"Governing Agreement").
 
The Board of Directors of Zurich Financial Services consists of ten members,
five of whom were initially selected by Zurich and five by B.A.T. Mr. Rolf
Hueppi, Zurich's current Chairman and Chief Executive Officer, became Chairman
and Chief Executive Officer of Zurich Financial Services. In addition to his
vote
                                        1
<PAGE>   15
 
by virtue of his position on the Board of Directors, as Chairman Mr. Hueppi will
have a tie-breaking vote on all matters except recommendations of the Audit
Committee, recommendations of the Remuneration Committee in respect of the
remuneration of the Chairman and the CEO, appointment and removal of the
Chairman and CEO, appointments to the Nominations, Audit and Remuneration
Committees and nominations to the Board of Directors not made through the
Nominations Committee.
 
The Group Management Board of Zurich Financial Services has been given
responsibility by the Board of Directors for the executive management of Zurich
Financial Services and has wide authority for such purpose. Of the 11 initial
members of the Group Management Board, eight are current members of the
Corporate Executive Board of Zurich (including Mr. Edmond D. Villani, CEO of the
Adviser, who is responsible for Global Asset Management for Zurich Financial
Services), and three are current B.A.T executives.
 
The Board of Directors of Zurich Allied AG initially consists of 11 members,
eight of whom are current Zurich directors and three of whom were proposed by
B.A.T. The Board of Directors of Allied Zurich p.l.c. also initially consists of
11 members, eight of whom are current B.A.T directors and three of whom were
proposed by Zurich. The parties have agreed that, as soon as possible, the Board
of Directors of Zurich Financial Services, Zurich Allied AG and Allied Zurich
p.l.c. will have identical membership.
 
Shareholder resolutions of Zurich Financial Services in general require approval
by at least 58% of all shares outstanding.
 
The Governing Agreement also contains provisions relating to dividend
equalization and provisions intended to ensure equal treatment of Zurich Allied
AG and Allied Zurich p.l.c. shareholders in the event of a takeover bid for
either company.
 
The B.A.T financial services businesses, which, since the closing of the
Transaction, are owned by Zurich Financial Services, include: the Farmers Group
of Insurance companies; the Eagle Star insurance business, primarily in the
U.K.; Allied-Dunbar, one of the leading U.K. unit-linked life insurance and
pensions companies; and Threadneedle Asset Management, which was formed
initially to manage the investment assets of Eagle Star and Allied-Dunbar, and
which, at December 31, 1997, had $58.8 billion under management. Overall, at
year-end 1997, the financial services businesses of B.A.T had $79 billion in
assets under management, including $18 billion in third party assets.
 
Zurich has informed each Fund that the financial services businesses of B.A.T do
not include any of B.A.T's tobacco businesses and that, after careful review,
Zurich has concluded that the tobacco-related liabilities connected with B.A.T's
tobacco business should not adversely affect Zurich or the present Zurich
subsidiaries, including the Adviser.
 
Governance arrangements that were put in place at the time of acquisition of
Zurich's 70% interest in the Adviser (which are discussed below under "Adviser")
remain unaffected by the Transaction. These arrangements preclude the making of
certain major decisions affecting the Adviser without the approval of the
directors of the Adviser elected by the non-Zurich shareholders of the Adviser.
 
Consummation of the Zurich-B.A.T Transaction may be deemed to have constituted
an "assignment," as that term is defined in the 1940 Act, of each Fund's Former
Investment Management Agreement with the Adviser. As required by the 1940 Act,
each of the Former Investment Management Agreements provided for its automatic
termination in the event of its assignment. Accordingly, a New Investment
Management Agreement between each Fund and the Adviser was approved by the Board
members of each Fund and is now being proposed for approval by shareholders of
both Funds. The Adviser has received an exemptive order from the Securities and
Exchange Commission (the "SEC" or the "Commission"), permitting it to implement,
without prior shareholder approval, the New Investment Management Agreements for
a period of up to 150 days after the consummation of the Transaction, which
occurred on September 7, 1998. A copy of the master form of the New Investment
Management Agreement is attached hereto as Exhibit A. In accordance with the
exemptive order, the advisory fees paid by both Funds to the Adviser under a New
Investment Management Agreement have been held in an interest-bearing escrow
account, and both Funds will continue to deposit such fees in escrow until
shareholder approval of a New

                                        2
<PAGE>   16
 
Investment Management Agreement. If an agreement is not approved, the fees shall
be returned to the applicable Fund. THE NEW INVESTMENT MANAGEMENT AGREEMENT IS
SUBSTANTIALLY IDENTICAL TO THE FORMER INVESTMENT MANAGEMENT AGREEMENT, EXCEPT
FOR THE DATES OF EXECUTION AND TERMINATION. The material terms of the Former
Investment Management Agreements are described under "Description of the
Investment Management Agreements" below.
 
BOARD RECOMMENDATION.
 
On July 16, 1998, the Boards of both Funds met and the Board members, including
the Board members who are not parties to such agreement or "interested persons"
(as defined under the 1940 Act) (the "Non-Interested Trustees" or
"Non-Interested Board members") of any such party, voted to approve the New
Investment Management Agreements and to recommend approval to the shareholders
of each applicable Fund.
 
For information about Board deliberations and the reasons for their
recommendation, please see "Board Evaluation" near the end of this Item 1.
 
DESCRIPTION OF THE INVESTMENT MANAGEMENT AGREEMENTS.
 
Under the Investment Management Agreements, the Adviser provides both Funds with
continuing investment management services. The Adviser also determines which
securities should be purchased, held, or sold, and what portion of both Funds'
assets should be held uninvested, subject to each Declaration of Trust, By-Laws,
investment objectives, policies and restrictions, the provisions of the 1940
Act, and such policies and instructions as the Trustees may have determined.
 
Both Investment Management Agreements provide that the Adviser will provide
continuing management of the assets of both Funds in accordance with each Fund's
investment objectives, policies and restrictions, furnish at its expense office
space and facilities to both Funds and render administrative services on behalf
of each Fund necessary for both Funds' operations and not provided by persons
not parties to the agreement including, but not limited to, preparing reports to
and meeting materials for the Board and reports and notices to Fund
shareholders; supervising, negotiating contractual arrangements with, to the
extent appropriate, and monitoring the performance of various third-party and
affiliated service providers to both Funds (such as both Funds' accounting

accountants, attorneys, printers, underwriters, brokers and dealers, insurers
and others) and other persons in any capacity deemed necessary or desirable to
Fund operations; preparing and making filings with the SEC and other regulatory
and self-regulatory organizations, including but not limited to, preliminary and
definitive proxy materials, post-effect amendments to the registration
statement, semi-annual reports on Form N-SAR; overseeing the tabulation of
proxies by both Funds' transfer agent; assisting in the preparation and filing
of both Funds' federal, state and local tax returns; preparing and filing both

relations matters; monitoring the valuation of portfolio securities and the
calculation of net asset value; monitoring the registration of shares of both
Funds under applicable federal and state securities laws; maintaining or causing

shareholders' and other meetings, and their expenses incurred in connection with
litigation and the legal obligation they may have to indemnify officers and
Trustees with respect thereto. Both Funds are also responsible for the
maintenance of books and records which are required to be maintained by both

individual consent to serve and to any limitations imposed by law. Both Funds
are responsible for the fees and expenses (specifically including travel
expenses relating to Fund business) of Trustees not affiliated with the Adviser.
Under the Investment Management Agreements, the Adviser also pays both Funds'
share of payroll taxes, as well as expenses, such as travel expenses (or an
appropriate portion thereof), of Trustees and officers of both Funds who are
directors, officers or employees of the Adviser.
 
For the services and facilities furnished, both Funds pay a monthly investment
management fee based upon the value of each Fund's average daily net assets. See
"PROPOSAL 2. APPROVAL OF THE REORGANIZATION -- Comparison of the Combined Fund
with the Short-Intermediate Fund -- ADVISORY AND OTHER FEES." During the fiscal
year ended August 31, 1998, the Adjustable Rate Fund paid $415,000 and during
the fiscal year ended September 30, 1998, the Short-Intermediate Fund paid
$920,000 to the Adviser.
 
Each Investment Management Agreement further provides that the Adviser shall be
liable for any error of judgement or mistake of law suffered by either Fund or
of any loss resulting from willful misfeasance, bad faith or gross negligence on
the part of the Adviser in the performance of its duties under such agreement.
The Investment Management Agreements also provide that purchase and sale
opportunities, which are suitable for more than one client of the Adviser, will
be allocated by the Adviser in an equitable manner.
 
Each Investment Management Agreement may be terminated without penalty upon
sixty (60) days written notice by either party. Both Funds may agree to
terminate their Investment Management Agreement either by a vote of a majority
of the outstanding voting securities of both Funds, or by a vote of their Board.
An Investment Management Agreement may also be terminated at any time without
penalty by the vote of a majority of the outstanding voting securities of either
Fund or by a vote of the Board if a court establishes that the Adviser or any of
its officers or Trustees has taken any action resulting in a breach of the
Adviser's
 
                                        4
<PAGE>   18
 
covenants under the Investment Management Agreement. As stated above, an
Investment Management Agreement automatically terminates in the event of its
assignment.
 
The Adviser has acted as Adviser for both Funds since December 31, 1997. Each
Former Investment Management Agreement is dated December 31, 1997, and was last
approved for continuance by the respective Board on January 20, 1998. The
shareholders of both Funds approved a Former Investment Management Agreement on
December 3, 1997. Each Former Investment Management Agreement continues until
March 1, 1999. Each Former Investment Management Agreement was last submitted to
shareholders for approval in connection with the Zurich/Scudder alliance.
 
NEW INVESTMENT MANAGEMENT AGREEMENTS.
 
The New Investment Management Agreement for both Funds is dated as of the
consummation of the Transaction, which occurred on September 7, 1998. Both New
Investment Management Agreements will be in effect for an initial term ending on
March 1, 1999, and may continue thereafter from year to year only if
specifically approved at least annually by the vote of "a majority of the
outstanding voting securities" of the respective Fund, or by its Board and, in
either event, the vote of a majority of the Non-interested Board members, cast
in person at a meeting called for such purpose. At meetings held on September
18, 1998 the Board of both Funds, including a majority of the Non-Interested
Trustees, approved the continuance of both New Investment Management Agreements
through September 30, 1999. In the event that shareholders of a Fund do not
approve a New Investment Management Agreement, it will terminate. In such event,
the Board of such Fund will take such action as it deems to be in the best
interests of the Fund and its shareholders.
 
DIFFERENCES BETWEEN THE FORMER AND NEW INVESTMENT MANAGEMENT AGREEMENT.
 
The New Investment Management Agreements are substantially identical to the
Former Investment Management Agreements, except for the dates of execution and
termination.

In connection with the Scudder-Zurich Transaction (described above), pursuant to
which Zurich acquired a two-thirds interest in Scudder for $866.7 million in
cash in December 1997, Daniel Pierce, a Director of both Funds, sold 85.4% of
his holdings in Scudder to Zurich in cash.
 
Pursuant to the Security Holders Agreement which was entered into in connection
with Scudder-Zurich transaction), the Board of Directors of the Adviser consists
of four directors designated by ZHCA and ZKIH and three directors designated by
Management Representatives.
 
The Security Holders Agreement requires the approval of a majority of the
Scudder-designated Trustees for certain decisions, including changing the name
of the Adviser, effecting an initial public offering before April 15, 2005,
causing the Adviser to engage substantially in non-investment management and
related business, making material acquisitions or divestitures, making material
changes in the Adviser's capital structure, dissolving or liquidating the
Adviser, or entering into certain affiliated transactions with Zurich. The
Security Holders Agreement also provides for various put and call rights with
respect to Adviser's stock held by persons who were employees of the Adviser at
the time of the Scudder-Zurich Transaction, limitations on Zurich's ability to
purchase other asset management companies outside of the Adviser, rights of
Zurich to repurchase the Adviser's stock upon termination of employment of the
Adviser's personnel, and registration rights for stock held by stockholders of
Scudder continuing after the Scudder-Zurich Transaction.
 
Directors, officers and employees of the Adviser from time to time may enter
into transactions with various banks, including both Funds' custodian bank. It
is Adviser's opinion that the terms and conditions of those transactions will
not be influenced by existing or potential custodial or other Fund
relationships.
 
Investors Fiduciary Trust Company ("IFTC"), 801 Pennsylvania, Kansas City,
Missouri 64105, is both Funds' transfer agent and dividend-paying agent.
Pursuant to a services agreement with IFTC, Kemper

<PAGE>   20
 
Service Company ("KSvC"), an affiliate of the Adviser, serves as Shareholder
Service Agent of both Funds for which IFTC serves as transfer and
dividend-paying agent and, as such, performs all of IFTC's duties as transfer
agent and dividend-paying agent. IFTC receives as transfer agent, and pays to
KSvC, annual account fees plus account set up, maintenance, transaction and
out-of-pocket expense reimbursement. Kemper Distributors, Inc. ("KDI"), a
subsidiary of the Adviser, provides information and administrative services for
shareholders of both Funds pursuant to administrative services agreements. KDI
is also the principal underwriter and distributor of both Funds' shares and acts
as agent of both Funds in the sale of its shares. For the Class B shares and
Class C shares of each Fund, KDI receives a Rule 12b-1 distribution fee of 0.75%
of average daily net assets of each such class.
 
KSvC and KDI will continue to provide transfer agency and underwriting,
administrative and distribution services, respectively, to the Funds, as
described above, under the current arrangements if the New Investment Management
Agreements are approved.
 
Exhibit B sets forth (for both Funds' last fiscal year end, unless otherwise
noted) the fees and other information regarding investment companies advised by
the Adviser.
 
BROKERAGE COMMISSIONS ON PORTFOLIO TRANSACTIONS.
 
To the maximum extent feasible, the Adviser places orders for portfolio
transactions through Scudder Investors Services, Inc. ("SIS"), Two International
Place, Boston, Massachusetts 02110, which in turn places orders on behalf of the
Funds with issuers, underwriters or other brokers and dealers. SIS is a
corporation registered as a broker/dealer and a subsidiary of the Adviser. In
selecting brokers and dealers with which to place portfolio transactions for a
Fund, the Adviser may consider sales of shares of the Funds and of other funds
managed by the Adviser or its affiliates. When it can be done consistently with
the policy of obtaining the most favorable net results, the Adviser may place
such orders with brokers and dealers who supply research, market and statistical
information to a Fund or to the Adviser. SIS does not receive any commissions,
fees or other remuneration from the Funds for this service. Allocation of
portfolio transactions is supervised by the Adviser.
 
BOARD EVALUATION.
 
Both Boards met on July 21, 1998 to consider the Transaction and its effects on
its Fund. The Boards met with senior management personnel of the Adviser. Both
Boards had the assistance of legal counsel, who prepared, among other things, an
analysis of the Board's fiduciary obligations. As a result of their review and
consideration of the Transaction and the proposed new investment management
agreement, the Board of both Funds voted unanimously to approve a New Investment
Management Agreement and to recommend it to the shareholders of their respective
Funds for approval.
 
In connection with its review, the Adviser represented to the Boards that: the
Transaction will have no effect on the operational management of either Fund;
the Transaction will not result in any change in the management or operations of
the Adviser; there will not be any increase in the advisory fee or any change in
any other provision, other than the term of the investment management agreement
as a result of the Transaction; the Transaction will not adversely affect the
Adviser's financial condition; and the Transaction should expand the Adviser's
global asset management capabilities and enhance the Adviser's research
capabilities, particularly with respect to the United Kingdom and Europe.
 
In connection with its deliberations, both Boards obtained certain assurances
from Zurich, including the following:
 
     - Zurich has provided to the Board such information as is reasonably
       necessary to evaluate a New Investment Management and other agreements.
 
     - Zurich looks upon the Adviser as the core of Zurich's global asset
       management strategy. With that focus, Zurich will devote to the Adviser
       and its affairs all attention and resources that are necessary to provide
       for its respective fund top quality investment management, shareholder,
       administrative and product distribution services.

                                        7
<PAGE>   21
 
     - The Transaction will not result in any change in either Fund's investment
       objectives or policies.
 
     - The Transaction will not result in any change in either management or
       operations of the Adviser or its subsidiaries.
 
     - The Transaction is not expected to result in any adverse change in the
       investment management or operations of its respective fund; and Zurich
       neither plans nor proposes, for the foreseeable future, to make any
       material change in the manner in which investment advisory services or
       other services are rendered to such Fund which has the potential to have
       a material adverse affect upon such Fund.
 
     - Zurich is committed to the continuance, without interruption, of services
       to the Funds of the type and quality currently provided by the Adviser
       and its subsidiaries, or superior thereto.
 
     - Zurich plans to maintain or enhance the Adviser facilities and
       organization.
 
     - In order to retain and attract key personnel, Zurich intends for the
       Adviser to maintain overall compensation policies and practices at market
       levels or better.
 
     - Zurich intends to maintain the distinct brand identity of the Kemper and
       Scudder Funds and is committed to strengthening and enhancing both brands
       and the distribution channels for both families of Funds, while
       maintaining their separate brand identity.
 
     - Zurich will promptly advise the Boards of decisions materially affecting
       the Adviser organization as they relate to its respective Fund. Neither
       this, nor any of the other above commitments will be altered by Zurich
       without the Board's prior consideration.
 
Zurich assured both Boards that it intends to comply with Section 15(f) of the
1940 Act. Section 15(f) provides a non-exclusive safe harbor for an investment
adviser to an investment company or any of its affiliated persons to receive any
amount or benefit in connection with a change in control of the investment
adviser so long as two conditions are met. First, for a period of three years
after the Transaction, at least 75% of the board members of the investment
company must not be "interested persons" of such investment adviser. The
composition of the Board of both Funds, currently and as proposed, would be in
compliance with this provision of Section 15(f). Second, an "unfair burden" must
not be imposed upon the investment company as a result of such transaction or
any express or implied terms, conditions or understandings applicable thereto.
The term "unfair burden" is defined in Section 15(f) to include any arrangement
during the two-year period after the Transaction whereby the investment adviser,
or any interested person of any such adviser, receives or is entitled to receive
any compensation, directly or indirectly, from the investment company or its
shareholders (other than fees for bona fide investment advisory or other
services) or from any person in connection with the purchase or sale of
securities or other property to, from or on behalf of the investment company
(other than bona fide ordinary compensation as principal underwriter for such
investment company). Zurich has advised the Boards that it is not aware of any
express or implied term, condition, arrangement or understanding that would
impose an "unfair burden" on any Fund as a result of the Transaction. Zurich has
agreed that it, and its affiliates, will take no action that would have the
effect of imposing an "unfair burden" on any Fund as a result of the
Transaction. In furtherance thereof, Zurich has undertaken to pay the costs of
preparing and distributing proxy materials to and of holding the meeting of each
Fund's shareholders as well as other fees and expenses in connection with the
Transaction, including the fees and expenses of legal counsel to both Funds and
the Non-Interested Board members.
 
Both Boards also considered whether tobacco-related liability connected with
B.A.T's tobacco business could adversely affect the Adviser and the services
provided to the Funds (See "Corporate Governance" above).
 
In evaluating the New Investment Management Agreements, both Boards took into
account that the fees and expenses payable by its Fund under a New Investment
Management Agreement are the same as under the Former Investment Management
Agreements, that the services provided to both Funds are the same and that the
other terms, except for the dates of execution and termination, are
substantially similar. Both

                                        8
<PAGE>   22
 
Boards also took into consideration that the portfolio managers and research
personnel would continue their functions with the Adviser after the Transaction.
Both Boards noted that, in previously approving the Former Investment Management
Agreements, both Boards had considered a number of factors, including: the
nature and quality of services provided by the Adviser; investment performance,
both of each Fund itself and relative to that of competitive investment
companies; investment management fees and expense ratios of both Funds and
competitive investment companies; the Adviser profitability from managing both
Funds; fall-out benefits to the Adviser from its relationship to both Funds,
including revenues derived from services provided to both Funds by affiliates of
the Adviser; and the potential benefits to the Adviser and to both Funds and its
shareholders of receiving research services from broker/dealer firms in
connection with the allocation of portfolio transactions to such firms.
 
Both Boards discussed the Transaction with the senior management of the Adviser
and Zurich and among themselves. Both Boards considered that Zurich is a large,
well-established company with substantial resources, and, as noted above, has
undertaken to devote such resources to the Adviser as are necessary to provide
both Funds with top quality services.
 
As a result of their review and consideration of the Transaction and the New
Investment Management Agreements, at is meeting on July 16, 1998, the Board of
both Funds voted unanimously to approve the New Investment Management Agreements
and to recommend it to the shareholders of both Funds for their approval.
 
FUND ACCOUNTING AGENT.
 
Scudder Fund Accounting Corporation is responsible for determining the net asset
value per share and maintaining the portfolio and general accounting records of
both Funds. Scudder Fund Accounting Corporation currently provides such services
at no fee.

PROPOSAL 2. APPROVAL OF THE REORGANIZATION (SHORT-INTERMEDIATE FUND ONLY)
 
A. SUMMARY
 
THE FOLLOWING IS A SUMMARY OF, AND IS QUALIFIED BY REFERENCE TO, THE MORE
COMPLETE INFORMATION CONTAINED IN THIS PROSPECTUS/PROXY STATEMENT AND THE
INFORMATION ATTACHED HERETO OR INCORPORATED HEREIN BY REFERENCE (INCLUDING THE
AGREEMENT AND PLAN OF REORGANIZATION). AS DISCUSSED MORE FULLY BELOW AND
ELSEWHERE IN THIS PROSPECTUS/PROXY STATEMENT, THE BOARD OF TRUSTEES FOR THE
SHORT-INTERMEDIATE FUND (THE "BOARD") BELIEVES THE PROPOSED REORGANIZATION (AS
DEFINED HEREIN) IS IN THE BEST INTERESTS OF SHAREHOLDERS OF THE
SHORT-INTERMEDIATE FUND AND WOULD NOT RESULT IN DILUTION OF SHAREHOLDERS'
INTEREST. AS A RESULT OF THE REORGANIZATION, SHAREHOLDERS OF THE
SHORT-INTERMEDIATE FUND WOULD ACQUIRE AN INTEREST IN THE COMBINED FUND (AS
DEFINED HEREIN).
 
Shareholders should read the entire Prospectus/Proxy Statement carefully
together with the Adjustable Rate Fund Prospectus incorporated herein by
reference and accompanying this Prospectus/Proxy Statement. This
Prospectus/Proxy Statement constitutes an offering of Class A, B and C shares of
the Combined Fund only.
 
THE REORGANIZATION
 
This Prospectus/Proxy Statement is being furnished to shareholders of the
Short-Intermediate Fund in connection with the proposed combination of the Fund
with and into the Adjustable Rate Fund pursuant to the terms and conditions of
the Agreement and Plan of Reorganization dated September 18, 1998 between the
Trust and the Adjustable Rate Fund (the "Agreement"). The Agreement provides
that the Short-Intermediate Fund would (i) transfer all of its assets to the
Adjustable Rate Fund in exchange solely for Class A, B and C shares of the
Adjustable Rate Fund and the Adjustable Rate Fund's assumption of the
liabilities of the Short-Intermediate Fund, (ii) distribute to each shareholder
of the Short-Intermediate Fund shares of the respective class of shares of the
Adjustable Rate Fund equal in value to their existing shares of the Fund as a
distribution in liquidation of the Fund, (iii) be liquidated, dissolved and
terminated as a series of the Kemper Portfolios in accordance with the Trust's
Declaration of Trust promptly following the Closing (as defined herein) and (iv)
the Adjustable Rate Fund would change its name to the Kemper Short-Term U.S.
Government Fund (the "Reorganization"). The Agreement also provides that the
Reorganization is contingent upon the approval of the shareholders of the
Adjustable Rate Fund of a new investment objective and policies. The Adjustable
Rate Fund as modified and combined with the Short-Intermediate Fund will be
referred to as the "Combined Fund."
 
The Board of Trustees of the Kemper Portfolios has determined that the
Reorganization is in the best interests of the Short-Intermediate Fund and that
the interests of existing shareholders of the Short-Intermediate Fund will not
be diluted as a result of the Reorganization. The Board of Kemper Portfolios
unanimously approved the Reorganization and the Agreement on September 18, 1998.
 
The Adviser will pay all of the Funds' costs associated with the Reorganization.
 
The Board is asking shareholders of the Short-Intermediate Fund to approve the
Reorganization at the Special Meeting to be held on December 16, 1998. If
shareholders of the Short-Intermediate Fund approve the Reorganization, it is
expected that the Closing of the Reorganization will be after the close of
business on                      , but it may be at a different time as
described herein.
 
THE BOARD RECOMMENDS THAT YOU VOTE "FOR" THE REORGANIZATION. FOR THE
SHORT-INTERMEDIATE FUND, APPROVAL OF THE REORGANIZATION REQUIRES THE FAVORABLE
VOTE OF THE HOLDERS OF A MAJORITY OF THE OUTSTANDING SHARES ENTITLED TO VOTE.
SEE "VOTING INFORMATION AND REQUIREMENTS" BELOW.
 
REASONS FOR THE PROPOSED REORGANIZATION
 
The Board believes that the proposed Reorganization would be in the best
interests of the Short-Intermediate Fund because it would permit the
shareholders of the Fund to (i) lower operating expenses as a percentage of net
assets due to the Combined Fund's larger net assets and greater economies of
scale;
 
                                       10
<PAGE>   24
 
(ii) reduce interest rate risk as the Combined Fund will have a maturity range
of 1-3 years versus a maturity of 2-5 years for the Short-Intermediate Fund, and
(iii) potentially increase income and total return as the Combined Fund will
have the ability to invest a portion of its assets in lower quality non-U.S.
Government securities.
 
In determining whether to recommend approval of the Reorganization to
shareholders of the Short-Intermediate Fund, the Board considered a number of
factors, including, but not limited to: (i) the expenses and advisory fees
applicable to the Short-Intermediate Fund and the Adjustable Rate Fund before
the Reorganization and the estimated expense ratios of the Combined Fund after
the Reorganization; (ii) the investment performance of the Short-Intermediate
Fund compared to the Adjustable Rate Fund; (iii) the terms and conditions of the
Agreement and whether the Reorganization would result in dilution of the
Short-Intermediate Fund's shareholder interests; (iv) the economies of scale
potentially realized through the combination of the Funds; (v) the compatibility
of the Funds' investment objectives; (vi) the compatibility of the Funds'
service features available to shareholders, including the retention of
applicable holding periods and exchange privileges; (vii) the future growth
prospects of the Short-Intermediate Fund; and (viii) the anticipated federal
income tax consequences of the Reorganization.
 
In this regard, the Board reviewed information provided by the Adviser relating
to the anticipated impact on the shareholders of the Short-Intermediate Fund as
a result of the Reorganization. The Board considered the probability that the
increase in asset levels of the combined fund after the Reorganization would
result in the following potential benefits for shareholders of the
Short-Intermediate Fund, although there can, of course, be no assurances in this
regard:
 
A.ECONOMIES OF SCALE. The combination is expected to create a Fund with total
  assets of approximately $230 million, with greater potential for increased
  assets and lower expenses.
 
B.PORTFOLIO MANAGEMENT PROCESS. The current managers of both the
  Short-Intermediate Fund and the Adjustable Rate Fund would be retained as the
  portfolio management team.
 
C.TRACK RECORD. For reporting purposes, the Combined Fund would retain the
  Adjustable Rate Fund track record, which extends back to 1987.
 
Based upon these and other factors, the Board unanimously determined that the
Reorganization is in the best interests of the Short-Intermediate Fund.
 
COMPARISON OF THE COMBINED FUND WITH THE SHORT-INTERMEDIATE FUND
 
INVESTMENT OBJECTIVES. The investment objective of the Combined Fund will be to
seek high current income and preservation of capital. The investment objective
of the Short-Intermediate Fund is to seek, with equal emphasis, high current
income and preservation of capital from a portfolio composed primarily of short
and intermediate-term U.S. Government securities.
 
INVESTMENT POLICIES. The Combined Fund will invest 100% of its total assets in
U.S. dollar-denominated securities and at least 65% of its total assets in
securities issued or guaranteed by the U.S. Government, its agencies or
instrumentalities, including repurchase agreements of such securities ("U.S.
Government Securities"). Under normal conditions, the Combined Fund would
maintain a dollar-weighted average portfolio maturity of less than three years.
The remaining 35% of the Combined Fund's assets could be invested in non-U.S.
Government Securities, including private collateralized mortgage obligations or
asset-backed securities rated investment grade quality (Baa or higher) by
Moody's Investor Service, Inc. ("Moody's") or (BBB or higher) by Standard &
Poor's Corporation ("S&P") and other fixed income securities (including debt and
preferred stock issues, convertibles and assignments and participations in
loans) with ratings of single-B or higher by Moody's or S&P or non-rated of
comparable quality in the opinion of the Adviser, with a 10% maximum limitation
on non-investment grade corporate debt securities. The Combined Fund would be
able to engage in financial futures, options, swaps (including caps, floors and
collars) and forward contracts transactions.
 
                                       11

The Short-Intermediate Fund, as a fundamental policy, invests at least 65% of is
total assets in U.S. Government Securities and repurchase agreements of U.S.
Government Securities. Under normal market conditions, the Fund will maintain a

rated at the time of purchase within the four highest grades by either Moody's
(Aaa, Aa, A or Baa) or S&P (AAA, AA, A or BBB); commercial paper that is rated
at the time of purchase within the two highest grades by either Moody's (Prime-1
or Prime-2) or S&P (A-1 or A-2); (c) bank certificates of deposit (including
term deposits) or bankers' acceptances issued by domestic banks (including their
foreign branches) and Canadian chartered banks having total assets in excess of
$1 billion; and (d) repurchase agreements with respect to any of the foregoing.

As of August 31, 1998, the Short-Intermediate Fund was invested in [more/less]
higher-rated securities than the Adjustable Rate Fund. Generally, on August 31,
1998, the average portfolio credit quality was       for the Short-Intermediate
Fund and       for the Adjustable Rate Fund. As discussed above, higher-rated
securities generally have less credit risk than lower rated securities.

(1) The SEC 30-Day Yield is computed in accordance with SEC rules by dividing
    the net investment income per share (computed in accordance with a
    standardized method prescribed by the rules) earned during the 30-day period
    by the maximum offering price.
 
The total returns and yields are not necessarily indicative of future results.
The performance of an investment company is the result of conditions in the
securities markets, portfolio management and operating expenses. Although
information such as that shown above is useful in reviewing a fund's performance
and in providing some basis for comparison with other investment alternatives,
it should not be used for comparison with other investments using different
reinvestment assumptions or time periods and would not be representative of the
Combined Fund operating with a different objective and policies.
 
INVESTMENT ADVISER. The Combined Fund will be, and the Short-Intermediate Fund
is, managed by the Adviser. The Adviser's principal office is located at 345
Park Avenue, New York, New York 10154. The Adviser is described fully above in
Proposal 1.
 
ADVISORY AND OTHER FEES. The contractual advisory fees of the Combined Fund will
be the same as those of the Short-Intermediate Fund. Pursuant to an investment
management agreement the Combined Fund will pay the Adviser an annual management
fee at the rates set forth below, which rates are the same rates currently being
paid by the Short-Intermediate Fund:

For the fiscal year ended August 31, 1998 the Adjustable Rate Fund paid the
Adviser $415,000. For a complete description of the advisory services provided
to the Adjustable Rate Fund, see the section of the Adjustable Rate Fund
Prospectus entitled "INVESTMENT MANAGER AND UNDERWRITER -- Investment Manager."
 
For the fiscal year ended September 30, 1998 the Short-Intermediate Fund paid
the Adviser $920,000. For a complete description of the advisory services
provided to the Short-Intermediate Fund, see the section of the
Short-Intermediate Fund Prospectus entitled "INVESTMENT MANAGER AND UNDERWRITER
- --Investment Manager."
 
UNDERWRITING AND DISTRIBUTION. The Combined Fund has distribution and service
plans which are substantially identical to those adopted by the
Short-Intermediate Fund (the "Distribution and Service Plans"). Pursuant to an
underwriting and distribution services agreement ("distribution agreement") with
the Combined Fund, Kemper Distributors, Inc. ("KDI"), 222 South Riverside Plaza,
Chicago, Illinois 60606, a wholly owned subsidiary of the Adviser, is the
principal underwriter and distributor of the Combined Fund's shares and acts as
agent of the Combined Fund in the sale of its shares. KDI will bear all its
expenses of providing services pursuant to the distribution agreement, including
the payment of any commissions. KDI provides for the preparation of advertising
or sales literature and bears the cost of printing and mailing prospectuses to
persons other than shareholders. KDI will bear the cost of qualifying and
maintaining the qualification of Combined Fund shares for sale under the
securities laws of the various states and the Combined Fund will bear the
expense of registering its shares with the Securities and Exchange Commission.
KDI may enter into related selling group agreements with various broker-
dealers, including affiliates of KDI, that provide distribution services to
investors. KDI also may provide some of the distribution services.
 
     CLASS A SHARES. KDI will receive no compensation from the Combined Fund as
     principal underwriter for Class A shares and will pay all expenses of
     distribution of the Combined Fund's Class A shares under the distribution
     agreements not otherwise paid by dealers or other financial services firms.
     KDI will retain the sales charge upon the purchase of shares and will pay
     or allow concessions or discounts to firms for the sale of the Combined
     Fund's shares.
 
     CLASS B SHARES. For its services under the distribution agreement, KDI will
     receive a fee from the Combined Fund, payable monthly, at the annual rate
     of .75% of average daily net assets of the Combined Fund attributable to
     Class B shares. This fee will be accrued daily as an expense of Class B
     shares. KDI will also receive any contingent deferred sales charges. KDI
     currently compensates firms for sales of Class B shares at a commission
     rate of 3.75%.
 
     CLASS C SHARES. For its services under the distribution agreement, KDI will
     receive a fee from the Combined Fund, payable monthly, at the annual rate
     of .75% of average daily net assets of each Fund attributable to Class C
     shares. This fee will be accrued daily as an expense of Class C shares. KDI
     will advance to firms the first year distribution fee at a rate of .75% of
     the purchase price of Class C shares. For periods after the first year, KDI
     currently pays firms for sales of Class C shares a distribution fee,
     payable quarterly, at an annual rate of .75% of net assets attributable to
     Class C shares maintained and serviced by the firm and the fee continues
     until terminated by KDI or a Fund. KDI will also receive any contingent
     deferred sales charges.
 
RULE 12B-1 PLAN. The Combined Fund will have Rule 12b-1 plans that provide for
fees payable as an expense of the Class B shares and the Class C shares that are
used by KDI to pay for distribution services for those classes, which are
approved and reviewed separately for the Class B shares and the Class C shares
in accordance with Rule 12b-1 under the 1940 Act, which regulates the manner in
which an investment company may, directly or indirectly, bear the expenses of
distributing its shares.
 
ADMINISTRATIVE SERVICES. KDI also provides information and administrative
services for shareholders of each Fund pursuant to administrative services
agreements ("administrative agreements"). KDI may enter into related
arrangements with various broker-dealer firms and other service or
administrative firms ("firms"), that provide services and facilities for their
customers or clients who are investors of the Funds. Such administrative
services and assistance may include, but are not limited to, establishing and
maintaining accounts and records, processing purchase and redemption
transactions, answering routine inquiries
                                       14
<PAGE>   28
 
regarding each Fund and its special features and such other administrative
services as may be agreed upon from time to time and permitted by applicable
statute, rule or regulation. KDI bears all its expenses of providing services
pursuant to the administrative agreement, including the payment of any service
fees. For services under the administrative agreements, each Fund pays KDI a
fee, payable monthly, at an annual rate of up to .25% of average daily net
assets of Class A, B and C shares of such Fund. With respect to Class A shares,
KDI then pays each firm a service fee at an annual rate of (a) in the case of
the Short-Intermediate Fund up to .25% of net assets and in the case of the
Adjustable Rate Fund up to .15% of net assets of those accounts that it
maintains and services for each Fund attributable to shares acquired prior to
October 1, 1993, and (b) up to .25% of net assets of those accounts that it
maintains and services for each Fund attributable to Class A shares acquired on
or after October 1, 1993. With respect to Class B shares and Class C shares, KDI
pays each firm a service fee, normally payable quarterly, at an annual rate of
up to .25% of net assets of those accounts in the Fund that it maintains and
services attributable to Class B shares and Class C shares, respectively. Firms
to which service fees may be paid include affiliates of KDI.
 
     CLASS A SHARES. For Class A shares, a firm becomes eligible for the service
     fee based on assets in the accounts in the month following the month of
     purchase and the fee continues until terminated by KDI or a Fund. The fees
     are calculated monthly and normally paid quarterly.
 
     CLASS B AND CLASS C SHARES. KDI currently advances to firms the first year
     service fee at a rate of up to .25% of the purchase price of such shares.
     For periods after the first year, KDI currently intends to pay firms a
     service fee at a rate of up to .25% (calculated monthly and normally paid
     quarterly) of the net assets attributable to Class B and Class C shares
     maintained and serviced by the firm and the fee continues until terminated
     by KDI or the Fund.
 
KDI also may provide some of the above services and may retain any portion of
the fee under the administrative agreements not paid to firms to compensate
itself for administrative functions performed for each Fund. Currently, the
administrative services fee payable to KDI is based only upon Fund assets in
accounts for which a firm provides administrative services and it is intended
that KDI will pay all the administrative services fee that it receives from each
Fund to firms in the form of service fees. The effective administrative services
fee rate to be charged against all assets of each Fund while this procedure is
in effect will depend upon the proportion of Fund assets that is in accounts for
which a firm provides administrative services as well as, with respect to Class
A shares (except for the Short-Intermediate Fund), the date when shares
representing such assets were purchased. In addition, KDI may, from time to
time, from its own resources, pay certain firms additional amounts for ongoing
administrative services and assistance provided to their customers and clients
who are shareholders of the Funds.
 
CUSTODIAN, TRANSFER AGENT AND SHAREHOLDER SERVICE AGENT. Investors Fiduciary
Trust Company ("IFTC"), 801 Pennsylvania Avenue, Kansas City, Missouri 64105, as
custodian, and State Street Bank and Trust Company, 225 Franklin Street, Boston,
Massachusetts 02110, as sub-custodian, have custody of all securities and cash

Pursuant to a services agreement with IFTC, Kemper Service Company ("KSvC") an
affiliate of the Adviser, serves as "Shareholder Service Agent" of the Funds and
as such, performs all of IFTC's duties as transfer agent and dividend-paying
agent. The Combined Fund has adopted the same arrangements. For a description of
shareholder service agent fees payable to the Shareholder Service Agent, see
"INVESTMENT MANAGER AND UNDERWRITER -- Custodian, Transfer Agent and Shareholder
Service Agent" in the Statement of Additional Information.
 
PORTFOLIO TRANSACTIONS. The Adviser places all orders for purchases and sales of
a Fund's securities. Subject to seeking best execution of orders, the Adviser
may consider sales of shares of a Fund and other funds managed by the Adviser or
its affiliates as a factor in selecting broker-dealers. See "PORTFOLIO
TRANSACTIONS" in the Statement of Additional Information.
 
The tables below set forth (i) the fees and expenses paid by the Adjustable Rate

Class C shares of the Combined Fund and the Short-Intermediate Fund have no
initial sales charges but are subject to a Rule 12b-1 distribution fee and a 1%
contingent deferred sales charge on redemptions made within one year of
purchase.
 
No contingent deferred sales charge will be imposed on Class B and Class C
shares of the Short-Intermediate Fund in connection with the Reorganization. The
holding period and conversion period for Class B and Class C shares of the
Combined Fund received in connection with the Reorganization will be measured
from the earlier of the time (i) the holder purchased such shares from the
Short-Intermediate Fund or (ii) the holder purchased such shares from any other
Kemper Fund and subsequently exchanged them for shares of the Short-Intermediate
Fund.

The stock transfer books of the Short-Intermediate Fund will be permanently
closed as of the date of Closing. Only redemption requests and transfer
instructions received in proper form by the close of business on the day prior
to the date of Closing will be fulfilled by the Short-Intermediate Fund.
Redemption requests or transfer instructions received by the Short-Intermediate
Fund after that date will be treated by the Fund as requests for the redemption
or instructions for transfer of the shares of the Combined Fund credited to the
accounts of the shareholders of the Short-Intermediate Fund. Redemption requests
or transfer instructions received by the Short-Intermediate Fund after the close
of business on the day prior to the date of Closing will be forwarded to the

- -------------------------
(1) The pro forma figures reflect the effect of the Short-Intermediate Fund
    Reorganization.
 
B. RISK FACTORS
 
SIMILARITY OF RISKS
 
The Combined Fund, as a non-fundamental policy, will invest 100% of its total
assets in U.S. dollar-denominated securities and 65% of its total assets in U.S.
Government Securities and repurchase agreements of such securities. The
Short-Intermediate Fund, as a fundamental policy, invests at least 65% of is
total assets in U.S. Government Securities and repurchase agreements of U.S.
Government Securities. U.S. Government Securities of the type in which the Funds
may invest have historically involved little risk of loss of principal if held
to maturity. The government guarantee of the U.S. Government Securities in the
Funds' portfolio, however, does not guarantee the net asset value of the shares
of the Fund. There are market risks inherent in all investments in securities
and the value of an investment in the Fund will fluctuate over time. Normally,
the value of the Funds' investment varies inversely with changes in interest
rates. For example, as interest rates rise the value of the Funds' investments
will tend to decline, and as interest rates fall the value of the Funds'
investments will tend to increase. In addition, the potential for appreciation
in the event of a decline in interest rates may be limited or negated by
increased principal prepayments in respect to certain mortgage-backed
securities.
 
DIFFERENCES IN RISKS
 
The remaining 35% of the Combined Fund's assets could be invested in private
collateralized mortgage obligations or asset-backed securities of investment
grade quality and other fixed income securities with ratings of single-B or
higher (or, if unrated, of comparable quality in the opinion of the Adviser)
with a 10% maximum limitation on non-investment grade securities. Lower-rated
and non-rated fixed-income securities, which are commonly referred to as "junk
bonds," have widely varying characteristics and quality. These lower rated
securities are considered, on balance, as predominantly speculative with respect
 
                                       21
<PAGE>   35
 
to capacity to pay interest and repay principal in accordance with the terms of
the obligations and generally will involve more credit risk than securities in
the higher rating categories.
 
Up to 35% of the assets of the Short-Intermediate Fund may be invested in fixed
income securities other than U.S. Government Securities. Such other fixed income
securities include: (a) corporate debt securities that are rated at the time of
purchase within the four highest grades by either Moody's (Aaa, Aa, A or Baa) or
S&P (AAA, AA, A or BBB); commercial paper that is rated at the time of purchase
within the two highest grades by either Moody's (Prime-1 or Prime-2) or S&P (A-1
or A-2); (c) bank certificates of deposit (including term deposits) or bankers'
acceptances issued by domestic banks (including their foreign branches) and
Canadian chartered banks having total assets in excess of $1 billion; and (d)
repurchase agreements with respect to any of the foregoing. Corporate debt
securities rated within the four highest grades by Moody's or S&P are generally
considered to be "investment grade." Like higher rated securities, securities
rated in the BBB or Baa categories are considered to have adequate capacity to
pay principal and interest, although they may have fewer protective provisions
than higher rated securities and thus may be adversely affected by severe
economic circumstances and are considered to have speculative characteristics.
 
The Combined Fund will be able to engage in financial futures, options, swaps
(including caps, floors and collars) and forward contracts transactions. The
Short-Intermediate Fund may engage in options or financial futures transactions
in connection with attempts to hedge its portfolio investments and not for
speculation. For a description of the risks associated with such investments see
the section of the Funds' Prospectus entitled "INVESTMENT OBJECTIVES, POLICIES
AND RISK FACTORS -- ADDITIONAL INFORMATION."
 
The Combined Fund will have a targeted average maturity of less than three
years. The Short-Intermediate Fund has a targeted average maturity of two to
five years. For more information on the actual maturity of the
Short-Intermediate Fund see "Comparison of the Combined Fund with the
Short-Intermediate Fund -- MATURITY AND DURATION." Funds with longer average
maturities and durations will generally be subject to greater interest rate
risk.
 
C. THE PROPOSED REORGANIZATION
 
The material features of the Agreement are summarized below. This summary does
not purport to be complete and is subject in all respects to the provisions of,
and is qualified in its entirety by reference to, the Agreement attached as
Appendix A to the Reorganization SAI, a copy of which may be obtained without
charge by calling the Funds at (800) 621-1048 and asking for the "Reorganization
SAI."
 
TERMS OF THE AGREEMENT
 
Pursuant to the Agreement, the Adjustable Rate Fund, an open-end management
investment company organized as a business trust, would acquire all of the
assets and the liabilities of the Short-Intermediate Fund on the date of the
Closing in consideration for Class A, B and C shares of the Adjustable Rate
Fund.
 
Subject to the Short-Intermediate Fund's shareholders approving the
Reorganization and the approval by the shareholders of the Adjustable Rate Fund
of a new investment objective and new investment policies, the closing (the
"Closing") will occur on [                     ] or such later date as soon as
practicable thereafter as the Adjustable Rate Fund and the Short-Intermediate
Fund may mutually agree.
 
On the date of the Closing, the Short-Intermediate Fund will transfer to the
Adjustable Rate Fund all of its assets and liabilities. The Adjustable Rate Fund
will in turn transfer to the Short-Intermediate Fund a number of its Class A, B
and C shares equal in value to the value of the net assets of the Fund,
transferred to the Adjustable Rate Fund as of the date of the Closing, as
determined in accordance with the valuation method described in the Adjustable
Rate Fund's then current prospectus. In order to minimize any potential for
undesirable federal income and excise tax consequences in connection with the
Reorganization, the Adjustable Rate Fund and the Short-Intermediate Fund may
individually distribute on or before the Closing all or substantially all of
their respective undistributed net investment income (including net capital
gains) as of such date.
                                       22
<PAGE>   36
 
The Short-Intermediate Fund will distribute in complete liquidation the Class A,
B and C shares of the Adjustable Rate Fund to the shareholders of the respective
class of the Fund promptly after the Closing and then will be liquidated,
dissolved and terminated as a series of the Trust in accordance with Kemper
Portfolios' Declaration of Trust.
 
The Short-Intermediate Fund has made certain standard representations and
warranties to the Adjustable Rate Fund regarding its capitalization, status and
conduct of business.
 
Unless waived in accordance with the Agreement, the obligations of the parties
to the Agreement are conditioned upon, among other things:
 
     1. the approval of the Reorganization by shareholders of the
        Short-Intermediate Fund;
 
     2. the approval by the shareholders of the Adjustable Rate Fund of a new
        investment objective and new investment policies;
 
     3. the absence of any rule, regulation, order, injunction or proceeding
        preventing or seeking to prevent the consummation of the transactions
        contemplated by the Agreement;
 
     4. the receipt of all necessary approvals, registrations and exemptions
        under federal and state laws;
 
     5. the truth in all material respects as of the Closing of the
        representations and warranties of the parties and performance and
        compliance in all material respects with the parties' agreements,
        obligations and covenants required by the Agreement;
 
     6. the effectiveness under applicable law of the registration statement of
        the Adjustable Rate Fund of which this Prospectus/Proxy Statement forms
        a part and the absence of any stop orders under the Securities Act of
        1933, as amended, pertaining thereto; and
 
     7. the receipt of opinions of counsel relating to, among other things, the
        tax-free nature of the Reorganization for federal income tax purposes.
 
The Agreement may be terminated or amended with respect to the Reorganization by
the mutual consent of the parties either before or after approval thereof by the
shareholders of the Short-Intermediate Fund, provided that no such amendment
after such approval shall be made if it would have a material adverse affect on
the interests of the Fund's shareholders. The Agreement also may be terminated
by the non-breaching party if there has been a material misrepresentation,
material breach of any representation or warranty, material breach of contract
or failure of any condition to Closing.
 
The Board recommends that you vote to approve the Reorganization, as it believes
the Reorganization is in the best interests of the Short-Intermediate Fund and
that the interests of existing shareholders will not be diluted as a result of
consummation of the proposed Reorganization.
 
DESCRIPTION OF SECURITIES TO BE ISSUED
 
SHARES OF BENEFICIAL INTEREST. Beneficial interests in the Adjustable Rate Fund
being offered hereby are represented by transferable Class A, B and C shares, no
par value per share. The Declaration of Trust of the Adjustable Rate Fund
permits the trustees, as they deem necessary or desirable, to create one or more
separate investment portfolios and to issue a separate series of shares for each
portfolio and, subject to compliance with the 1940 Act, to further subdivide the
shares of a series into one or more classes of shares for such portfolio.
 
VOTING RIGHTS OF SHAREHOLDERS. Holders of shares of the Adjustable Rate Fund are
entitled to one vote per share on matters as to which they are entitled to vote;
however, separate votes generally are taken by each series on matters affecting
an individual series.
 
The Adjustable Rate Fund operates as an open-end management investment company
registered with the SEC under the 1940 Act. In addition to the specific voting
rights described above, shareholders of the Adjustable Rate Fund are entitled,
under current law, to vote with respect to certain other matters, including
changes in fundamental investment policies and restrictions and the ratification
of the selection
                                       23
<PAGE>   37
 
of independent auditors. Moreover, under the 1940 Act, shareholders owning not
less than 10% of the outstanding shares of the Adjustable Rate Fund may request
that the board of trustees call a shareholders' meeting for the purpose of
voting upon the removal of trustee(s).
 
CONTINUATION OF SHAREHOLDER ACCOUNTS AND PLANS; SHARE CERTIFICATES
 
If the Reorganization is approved, the Adjustable Rate Fund will establish an
account for each Short-Intermediate Fund's shareholder containing the
appropriate number of shares of the Adjustable Rate Fund. The shareholder
services and shareholder programs of the Adjustable Rate Fund and the Short-
Intermediate Fund are substantially identical. Shareholders of the
Short-Intermediate Fund who are accumulating shares of the Short-Intermediate
Fund under the dividend reinvestment plan, or who are receiving payment under
the systematic withdrawal plan with respect to shares of the Short-Intermediate
Fund, will retain the same rights and privileges after the Reorganization in
connection with the Adjustable Rate Fund Class A, B or C shares received in the
Reorganization through substantially identical plans maintained by the
Adjustable Rate Fund. Investors Fiduciary Trust Company ("IFTC"), as custodian,
and State Street Bank and Trust Company, as sub-custodian, have custody of all
securities and cash of both Funds.
 
Upon approval of the Reorganization, shareholders of the Short-Intermediate Fund
who currently own shares in certificate form are asked to surrender these shares
to the Short-Intermediate Fund's shareholder service agent, KSvC.
Short-Intermediate Fund shareholders must submit a written request to IFTC in
order to receive certificates for their Adjustable Rate Fund shares. No
certificates for Adjustable Rate Fund shares will be issued as part of the
Reorganization except upon request.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
The following is a general discussion of the material federal income tax
consequences of the Reorganization to shareholders of the Short-Intermediate
Fund and shareholders of the Adjustable Rate Fund. The discussion set forth
below is for general information only and may not apply to a holder subject to
special treatment under the Internal Revenue Code of 1986, as amended (the
"Code"), such as a holder that is a bank, an insurance company, a dealer in
securities, a tax-exempt organization, a foreign person or that acquired its
Class A, B and C shares of the Short-Intermediate Fund pursuant to the exercise
of employee stock options or otherwise as compensation. It is based upon the
Code, legislative history, Treasury regulations, judicial authorities, published
positions of the Internal Revenue Service (the "Service") and other relevant
authorities, all as in effect on the date hereof and all of which are subject to
change or different interpretations (possibly on a retroactive basis). This
summary is limited to shareholders who hold their Short-Intermediate Fund shares
as capital assets. No advance rulings have been or will be sought from the
Service regarding any matter discussed in this Prospectus/Proxy Statement.
Accordingly, no assurances can be given that the Service could not successfully
challenge the intended federal income tax treatment described below.
Shareholders should consult their own tax advisers to determine the specific
federal income tax consequences of all transactions relating to the
Reorganization, as well as the effects of state, local and foreign tax laws and
possible changes to the tax laws.
 
The Reorganization is intended to qualify as a "reorganization" within the
meaning of Section 368(a)(1) of the Code. It is a condition to the Closing of
the Reorganization that the Kemper Portfolios and the Adjustable Rate Fund
receive an opinion from Vedder, Price, Kaufman & Kammholz ("Vedder Price")
substantially to the effect that for federal income tax purposes:
 
     1. The acquisition by the Adjustable Rate Fund of the assets of the
        Short-Intermediate Fund in exchange solely for Class A, B and C shares
        of the Adjustable Rate Fund and the assumption by the Adjustable Rate
        Fund of the liabilities of the Short-Intermediate Fund will qualify as
        tax-free reorganization within the meaning of Section 368(a)(1)(C) of
        the Code.
 
     2. No gain or loss will be recognized by the Short-Intermediate Fund or the
        Adjustable Rate Fund upon the transfer to the Adjustable Rate Fund of
        the assets of the Short-Intermediate Fund in
 
                                       24
<PAGE>   38
 
exchange solely for the Class A, B and C shares of the Adjustable Rate Fund and
the assumption by the Adjustable Rate Fund of the liabilities of the
Short-Intermediate Fund.
 
     3. The Adjustable Rate Fund's basis in the Short-Intermediate Fund's assets
        received in the Reorganization will equal the basis of such assets in
        the hands of the Short-Intermediate Fund immediately prior to the
        transfer, and the Adjustable Rate Fund's holding period of such assets
        will, in each instance, include the period during which the assets were
        held by the Short-Intermediate Fund.
 
     4. No gain or loss will be recognized by the shareholders of the
        Short-Intermediate Fund upon the exchange of their shares of the
        Short-Intermediate Fund for the Class A, B and C shares of the
        Adjustable Rate Fund.
 
     5. The aggregate tax basis in the Class A, B and C shares of the Adjustable
        Rate Fund received by the shareholders of the Short-Intermediate Fund
        will be the same as the aggregate tax basis of the shares of the
        Short-Intermediate Fund surrendered in exchange therefor.
 
     6. The holding period of the Class A, B and C shares of the Adjustable Rate
        Fund received by the shareholders of the Short-Intermediate Fund will
        include the holding period of the shares of the Short-Intermediate Fund
        surrendered in exchange therefor provided such surrendered shares of the
        Short-Intermediate Fund are held as capital assets by such shareholder.
 
In rendering its opinions, Vedder Price will rely upon certain representations
of the management of the Adjustable Rate Fund and the Short-Intermediate Fund
and assume that the Reorganization will be consummated as described in the
Agreement and that redemptions of shares of the Short-Intermediate Fund
occurring prior to the Closing and post-Closing redemptions of shares of the
Short-Intermediate Fund that are received in the Reorganization will consist
solely of redemptions in the ordinary course of business.
 
The Adjustable Rate Fund intends to be taxed under the rules applicable to
regulated investment companies as defined in Section 851 of the Code, which are
the same rules currently applicable to the Short-Intermediate Fund and its
shareholders.
 
EXPENSES
 
Expenses for the Reorganization will be paid by the Adviser.
 
As noted above, shareholders of the Short-Intermediate Fund may redeem their
shares or exchange their shares for shares of certain other open-end mutual
funds distributed by KDI at any time prior to the closing of the Reorganization.
See the Section of the Adjustable Rate Fund and the Short-Intermediate Fund
Prospectus entitled "SPECIAL FEATURES". Redemptions and exchanges of shares
generally are taxable transactions for federal income tax purposes, unless your
account is not subject to taxation, such as an individual retirement account or
other tax-qualified retirement plan. Shareholders should consult with their own
tax advisers regarding the federal, state and local tax consequences of
potential transactions.
 
LEGAL MATTERS
 
Certain legal matters concerning the federal income tax consequences of the
Reorganization and issuance of Class A, B and C shares of the Adjustable Rate
Fund will be passed on by Vedder, Price, Kaufman & Kammholz, 222 North LaSalle
Street, Chicago, Illinois 60601.

D. RECOMMENDATION OF THE BOARD
 
The Board of the Kemper Portfolios has unanimously approved the Agreement and
has determined that participation in the Reorganization is in the best interests
of the Short-Intermediate Fund. THE BOARD OF TRUSTEES UNANIMOUSLY RECOMMENDS
THAT SHAREHOLDERS VOTE "FOR" THE PROPOSED REORGANIZATION.
 
                                       26
<PAGE>   40
 
PROPOSAL 3. APPROVAL OF NEW INVESTMENT OBJECTIVE AND THE REVISION OF CERTAIN
            FUNDAMENTAL INVESTMENT POLICIES (ADJUSTABLE RATE FUND ONLY)
 
THE BOARD RECOMMENDS THAT YOU VOTE "FOR" THE APPROVAL OF A NEW INVESTMENT
OBJECTIVE AND THE REVISION OF CERTAIN FUNDAMENTAL INVESTMENT POLICIES.
 
In connection with the reorganization of the Short-Intermediate Fund into the
Adjustable Rate Fund, you are being asked to approve a new investment objective
and policies that will give the Adjustable Rate Fund greater flexibility to
invest in fixed rate U.S. government securities and broaden the ability of the
Adjustable Rate Fund to invest in other lower quality non-U.S. government
securities. The Adviser believes that the proposed new investment policies of
the Adjustable Rate Fund will provide more diversification of investment choices
and could increase the potential for higher income and better total returns. If
Proposal 3 is approved these new investment objective and policies of the
Adjustable Rate Fund will be non-fundamental and the Adjustable Rate Fund will
change its name to the Kemper Short-Term U.S. Government Fund.
 
Also, you will be asked to approve other changes to the Adjustable Rate Fund's
fundamental policies. The 1940 Act requires an investment company to adopt
policies governing certain specified activities, which can be changed only by a
shareholder vote. Policies that cannot be changed or eliminated without a
shareholder vote are referred to in this Proxy Statement as "fundamental"
policies. The purposes of this Proposal are to eliminate the requirement of
shareholder approval to change policies except where required by the 1940 Act
and to provide the maximum permitted flexibility in those policies that do
require shareholder approval. Management has advised the Board that some of the
Adjustable Rate Fund's fundamental policies that are not required to be such
under the 1940 Act were adopted in the past as a result of now rescinded
regulatory requirements and no longer serve any useful purpose. Management
believes that other fundamental policies, as well as the classification of the
Adjustable Rate Fund's investment objective(s) as fundamental, are unnecessary
because the provisions of the 1940 Act or Federal tax law, together with the
disclosure requirements of the Federal securities laws, provide adequate
safeguards for a fund and its shareholders. The Proposal is described in more
detail below.
 
This Proposal is sub-divided into the following four sections:
 
(A) NEW INVESTMENT OBJECTIVE AND POLICIES AND ELIMINATION OF SHAREHOLDER
APPROVAL REQUIREMENT TO AMEND INVESTMENT OBJECTIVE AND CERTAIN FUNDAMENTAL
POLICIES. The first section of this Proposal seeks shareholder approval to
change the Adjustable Rate Fund's investment objective and policies. The new
investment objective and policies will eliminate the requirement that under
normal market conditions the Adjustable Rate Fund will invest at least 65% of
its total assets in adjustable rate securities issued or guaranteed by the U.S.
Government, its agencies or instrumentalities. Instead the new investment
objective and policies would give the Adjustable Rate Fund greater flexibility
to invest in fixed rate U.S. government securities and broaden the ability of
the Adjustable Rate Fund to invest in other lower quality non-U.S. government
securities. The Adviser believes that, while the change in approach may result
in more volatility of principal, the broadened investment flexibility to invest
in lower quality non-U.S. Government securities could provide the potential for
greater income and total returns. In addition, eliminating the shareholder vote
requirement for amending the investment objective and policies of the Adjustable
Rate Fund is intended to enhance the Adjustable Rate Fund's investment
flexibility in the event of changing circumstances.
 
(B) ELIMINATION OF SHAREHOLDER APPROVAL REQUIREMENT TO AMEND INVESTMENT
POLICIES. The Adjustable Rate Fund currently requires shareholder approval to
amend "investment objectives and fundamental policies." The second section of
this Proposal seeks shareholder approval of the elimination of the shareholder
vote requirement for amending "policies" which are not otherwise specifically
identified as fundamental. Management believes that categorizing all policies as
fundamental restricts the Adjustable Rate Fund's investment flexibility and its
ability to respond to changing regulatory and industry conditions.
 
                                       27
<PAGE>   41
 
(C) REVISION OF CERTAIN FUNDAMENTAL INVESTMENT POLICIES MANDATED BY THE 1940
ACT. Each of the fundamental policies proposed for revision relates to an
activity that the 1940 Act requires be governed by a fundamental policy. Each
proposed revision is, in general, intended to provide the Adjustable Rate Fund's
Board with the maximum flexibility permitted under the 1940 Act, and to promote
simplicity among the Adjustable Rate Fund's policies.
 
(D) ELIMINATION OF SHAREHOLDER APPROVAL TO CHANGE OTHER FUNDAMENTAL
POLICIES. This Proposal seeks to eliminate certain policies that are
specifically designated as fundamental but which are not required to be
fundamental under the 1940 Act. The Board of the Adjustable Rate Fund
anticipates adopting certain of these policies as non-fundamental. Any policy
that is not designated as fundamental can be modified or eliminated by the
Board, and, as indicated below, management intends to recommend to the Board the
elimination of several of them as being inappropriate or unnecessary under
current conditions.
 
Each proposed policy is identified in bold-type below.
 
The Adjustable Rate Fund's current fundamental policies are set forth in Exhibit
D. Changes in fundamental policies that are approved by shareholders, as well as
changes in non-fundamental policies that are adopted by a Board, will be
reflected in the Adjustable Rate Fund's prospectus and other disclosure
documents. Any change in the method of operation of the Adjustable Rate Fund
will require prior Board approval. Except as specifically indicated below, the
Board of the Adjustable Rate Fund does not presently intend to change the
investment policies of the Adjustable Rate Fund.
 
Approval of each item of this Proposal with respect to the Adjustable Rate Fund
requires the affirmative vote of a majority of the outstanding voting
securities, as defined above, of the Adjustable Rate Fund. If the shareholders
of the Adjustable Rate Fund fail to approve the proposed revisions or
elimination of any fundamental policy, the current such policy will remain in
effect.
 
A. NEW INVESTMENT OBJECTIVE AND POLICIES AND ELIMINATION OF SHAREHOLDER APPROVAL
   REQUIREMENT TO AMEND INVESTMENT OBJECTIVE AND CERTAIN FUNDAMENTAL POLICIES.
 
PROPOSAL 3.1:
 
The language in the current prospectus for the Adjustable Rate Fund provides
that "the Adjustable Rate Fund seeks high current income consistent with low
volatility of principal." -- is to be replaced by -- "THE ADJUSTABLE RATE FUND
SEEKS HIGH CURRENT INCOME AND PRESERVATION OF CAPITAL."
 
Currently the Adjustable Rate Fund Prospectus provides: "[u]nder normal market
conditions the [Adjustable Rate] Fund will, as a fundamental policy, invest at
least 65% of its total assets in adjustable rate securities issued or guaranteed
by the U.S. Government, its agencies or representatives ("U.S. Government
Securities")."
 
Currently the Adjustable Rate Fund Prospectus also provides: "the [Adjustable
Rate] Fund may also invest up to 35% of its total assets in securities other
than adjustable rate U.S. Government Securities including, without limitation,
primary issued mortgage-backed securities, commercial paper and other debt
obligations of corporations and other business organizations, certificates of
deposits, banker's acceptances and time deposits and other debt securities such
as convertible securities and preferred stocks. These securities will, at the
time of purchase, be rated within the two highest grades (Aaa or Aa) assigned by
Moody's Investor Service, Inc. ("Moody's") or (AAA or AA) by Standard & Poor's
Corporation ("S&P"), or will be non-rated but of comparable quality in the
opinion of the Adviser."
 
IF THIS ITEM IS APPROVED BY SHAREHOLDERS, THE ADJUSTABLE RATE FUND PROSPECTUS
WILL PROVIDE: "THE FUND WILL INVEST 100% OF ITS TOTAL ASSETS IN U.S.
DOLLAR-DENOMINATED SECURITIES AND NORMALLY AT LEAST 65% OF ITS TOTAL ASSETS IN
SECURITIES ISSUED OR GUARANTEED BY THE U.S. GOVERNMENT, ITS AGENCIES OR
INSTRUMENTALITIES, INCLUDING REPURCHASE AGREEMENTS OF SUCH SECURITIES ("U.S.
GOVERNMENT SECURITIES"). UNDER NORMAL CONDITIONS, THE FUND WILL MAINTAIN A
DOLLAR WEIGHTED AVERAGE PORTFOLIO MATURITY OF LESS THAN THREE YEARS. THE FUND
MAY ALSO INVEST UP TO 35% OF ITS TOTAL ASSETS IN SECURITIES OTHER THAN U.S.
GOVERNMENT SECURITIES. SUCH NON-U.S. GOVERNMENT SECURITIES INCLUDE, BUT ARE NOT
LIMITED TO, PRIVATE CMO'S AND OTHER ASSET-BACKED
 
                                       28
<PAGE>   42
 
SECURITIES RATED INVESTMENT GRADE (BA OR HIGHER) BY MOODY'S INVESTORS SERVICE,
INC. ("MOODY'S") OR (BB OR HIGHER) BY STANDARD & POOR'S CORPORATION ("S&P") AND
IN OTHER FIXED INCOME SECURITIES RATED SINGLE-B OR HIGHER BY MOODY'S OR S&P OR
UNRATED SECURITIES OF COMPARABLE QUALITY IN THE OPINION OF THE ADVISER, PROVIDED
THAT THE FUND WILL INVEST ONLY UP TO 10% OF ITS TOTAL ASSETS IN CORPORATE DEBT
SECURITIES RATED BELOW INVESTMENT GRADE. THE FUND MAY INVEST IN ANY NON-RATED
SECURITIES THAT ARE DETERMINED TO BE OF COMPARABLE QUALITY IN THE OPINION OF THE
ADVISER."
 
Management believes that the proposed new investment objective and policies of
the Adjustable Rate Fund will provide more diversification of investment choice.
While the Adjustable Rate Fund would still be allowed to invest in adjustable
rate securities, the Adviser would have greater flexibility to use other
short-term fixed income investments. Although the change in investment approach
may result in more volatility of principal, the Adviser believes that the
ability to invest in lower quality non-U.S. Government Securities could
potentially result in higher income and total returns.
 
IF THIS PROPOSAL IS APPROVED BY THE SHAREHOLDERS, THE INVESTMENT OBJECTIVE OF
THE ADJUSTABLE RATE FUND AND THE POLICIES IDENTIFIED ABOVE IN THE ADJUSTABLE
RATE FUND PROSPECTUS WILL NOT BE CLASSIFIED AS FUNDAMENTAL.
 
Management believes that leaving the power to modify investment objectives up to
the discretion of the Board would strengthen the Adjustable Rate Fund's ability
to respond to changing circumstances. The Board of the Adjustable Rate Fund does
not presently intend to further modify any investment objective, other than in
connection with this Proposal, and would disclose any such future changes to
applicable shareholders by amending the Adjustable Rate Fund's Prospectus and
Statement of Additional Information.
 
B. ELIMINATION OF SHAREHOLDER APPROVAL TO AMEND INVESTMENT POLICIES
 
PROPOSAL 3.2:
 
IF THIS PROPOSAL IS APPROVED BY THE SHAREHOLDERS OF THE ADJUSTABLE RATE FUND,
THE "INVESTMENT POLICIES" OF THE ADJUSTABLE RATE FUND WILL NOT BE CLASSIFIED AS
FUNDAMENTAL EXCEPT AS OTHERWISE PROVIDED IN THIS PROSPECTUS/PROXY STATEMENT.
 
This proposal is intended to provide the Adjustable Rate Fund with clarity of
disclosure and the investment flexibility necessary to respond to changing
circumstances by eliminating the shareholder vote requirement for amending
"investment policies" which are not specifically identified as fundamental. The
Adjustable Rate Fund's Prospectus currently contains a statement that
characterizes all "investment policies" as fundamental. Management believes that
this current statement is overbroad. The current statement unnecessarily
restricts the Adjustable Rate Fund's flexibility and may make it more difficult
to respond to changing conditions. Management believes that removing the
fundamental characterization of all policies not otherwise specifically
identified as fundamental is consistent with industry standards and would allow
the Adjustable Rate Fund and its Board to modify operating policies in light of
changes in the investment management industry, market conditions and the
regulatory environment, but only consistent with applicable law, the Adjustable
Rate Fund's investment objective and its clearly-identified fundamental
policies.
 
C. REVISION OF CERTAIN FUNDAMENTAL INVESTMENT POLICIES MANDATED BY THE 1940 ACT
 
DIVERSIFICATION
 
PROPOSAL 3.3:
 
IF THIS PROPOSAL IS APPROVED BY THE SHAREHOLDERS OF THE ADJUSTABLE RATE FUND,
THE ADJUSTABLE RATE FUND WILL REMAIN A "DIVERSIFIED" FUND UNDER THE 1940 ACT,
BUT WILL NOT BE SUBJECT TO ADDITIONAL REQUIREMENTS THAT ARE MORE RESTRICTIVE
THAN THE 1940 ACT.
 
The Adjustable Rate Fund is currently classified as a diversified open-end
investment company. Under the 1940 Act, a fund is "diversified" if, with respect
to 75% of its total assets, it may not invest more than 5% of the value of its
total assets in securities issued by any one issuer or purchase more than 10% of
the voting securities of any one issuer, except in each case in U.S. Government
securities or securities issued by
                                       29
<PAGE>   43
 
other investment companies. Currently, the Adjustable Rate Fund has adopted
additional diversification policies.
 
Under the current diversification policies, the Adjustable Rate Fund may not
invest more than 5% of its assets in the securities of any one issuer, except
U.S. Government securities. The Adjustable Rate Fund's policies also contain a
separate restriction prohibiting the purchase of more than 10% of the voting
securities of any one issuer. Accordingly, the elimination of the separate
diversification policies for the Adjustable Rate Fund means that the Adjustable
Rate Fund must comply with only the 1940 Act diversification requirements. As a
result, the elimination of the separate diversification policies that apply to
100% of the value of the Adjustable Rate Fund total assets will cause the
Adjustable Rate Fund to have less restrictive diversification requirements.
 
BORROWING
 
PROPOSAL 3.4:
 
IF THIS PROPOSAL IS APPROVED BY SHAREHOLDERS OF THE ADJUSTABLE RATE FUND, THE
ADJUSTABLE RATE FUND MAY NOT BORROW MONEY, EXCEPT AS PERMITTED UNDER THE
INVESTMENT COMPANY ACT OF 1940, AS AMENDED, AND AS INTERPRETED OR MODIFIED BY
REGULATORY AUTHORITY HAVING JURISDICTION, FROM TIME TO TIME.
 
The current policy of the Adjustable Rate Fund prohibits borrowing money, except
as a temporary measure for extraordinary or emergency purposes, in which case
the Adjustable Rate Fund may borrow up to one-third of the value of its total
assets. Additionally, the Adjustable Rate Fund may not borrow for leverage or
make investments while borrowings are outstanding.
 
The proposed policy would permit the Adjustable Rate Fund to engage in borrowing
in a manner and to the full extent permitted by applicable law. The 1940 Act
requires borrowings to have 300% assets coverage, which means, in effect, that a
Fund would be permitted to borrow up to an amount equal to 50% of its total
assets under the proposed borrowing policy. Additionally, under the proposed
policy, the Adjustable Rate Fund would not be limited to borrowing for temporary
or emergency purposes, could borrow for leverage, and could purchase securities
for investment while borrowings are outstanding. However, the Board has no
current intention of authorizing any of these practices. If the Board authorized
the Adjustable Rate Fund to borrow for leverage, such borrowings would increase
the Adjustable Rate Fund's volatility and the risk of loss in a declining
market.
 
SENIOR SECURITIES
 
PROPOSAL 3.5:
 
IF THIS PROPOSAL IS APPROVED BY SHAREHOLDERS OF THE ADJUSTABLE RATE FUND, THE
ADJUSTABLE RATE FUND MAY NOT ISSUE SENIOR SECURITIES, EXCEPT AS PERMITTED UNDER
THE INVESTMENT COMPANY ACT OF 1940, AS AMENDED, AND AS INTERPRETED OR MODIFIED
BY REGULATORY AUTHORITY HAVING JURISDICTION, FROM TIME TO TIME.
 
The current policy of the Adjustable Rate Fund prohibits the issuance of senior
securities (i.e., securities which are obligations or instruments evidencing
indebtedness) except as permitted under the 1940 Act. The proposed policy
re-words the current policy without making any material changes.
 
CONCENTRATION
 
PROPOSAL 3.6:
 
IF THIS PROPOSAL IS APPROVED BY SHAREHOLDERS OF THE ADJUSTABLE RATE FUND, THE
ADJUSTABLE RATE FUND MAY NOT CONCENTRATE ITS INVESTMENTS IN A PARTICULAR
INDUSTRY, AS THAT TERM IS USED IN THE INVESTMENT COMPANY ACT OF 1940, AS
AMENDED, AND AS INTERPRETED OR MODIFIED BY REGULATORY AUTHORITY HAVING
JURISDICTION, FROM TIME TO TIME.
 
While the 1940 Act does not define what constitutes "concentration" in an
industry, the staff of the Commission takes the position that investment of more
than 25% of a Fund's assets in an industry constitutes concentration. If a Fund
concentrates in an industry, it must at all times have more than 25%
 
                                       30
<PAGE>   44
 
of its assets invested in that industry, and if its policy is not to
concentrate, as is the case with each of the Adjustable Rate Funds, it may not
invest more than 25% of its assets in the applicable industry, unless, in either
case, the Fund discloses the specific conditions under which it will change from
concentrating to not concentrating or vice versa.
 
The Adjustable Rate Fund's current policy in effect prohibits the purchase of
securities if it would result in more than 25% of the Adjustable Rate Fund's
total assets being invested in the same industry. For the Adjustable Rate Fund,
there are expectations for U.S. Government securities, including collateralized
obligations. In some cases, what constitutes an industry for the purposes of
this restriction is included in the policy itself. A Fund is permitted to adopt
reasonable definitions of what constitutes an industry, or it may use standard
classifications promulgated by the Commission, or some combination thereof.
Because a Fund may create its own reasonable industry classifications,
management believes that it is not necessary to include such matters in the
fundamental policy of the Adjustable Rate Fund.
 
UNDERWRITING OF SECURITIES
 
PROPOSAL 3.7:
 
IF THIS PROPOSAL IS APPROVED BY SHAREHOLDERS OF THE ADJUSTABLE RATE FUND, THE
ADJUSTABLE RATE FUND MAY NOT ENGAGE IN THE BUSINESS OF UNDERWRITING SECURITIES
ISSUED BY OTHERS, EXCEPT TO THE EXTENT THAT A FUND MAY BE DEEMED TO BE AN
UNDERWRITER IN CONNECTION WITH THE DISPOSITION OF PORTFOLIO SECURITIES.
 
The proposed underwriting policy has been re-worded without making any material
changes.
 
INVESTMENT IN REAL ESTATE
 
PROPOSAL 3.8:
 
IF THIS PROPOSAL IS APPROVED BY SHAREHOLDERS OF THE ADJUSTABLE RATE FUND, THE
ADJUSTABLE RATE FUND MAY NOT PURCHASE OR SELL REAL ESTATE, WHICH TERM DOES NOT
INCLUDE SECURITIES OF COMPANIES WHICH DEAL IN REAL ESTATE OR MORTGAGES OR
INVESTMENTS SECURED BY REAL ESTATE OR INTERESTS THEREIN, EXCEPT THAT THE FUND
RESERVES FREEDOM OF ACTION TO HOLD AND TO SELL REAL ESTATE ACQUIRED AS A RESULT
OF THE FUND'S OWNERSHIP OF SECURITIES.
 
The proposed real estate policy re-words the current policies without making any
material changes.
 
PURCHASE OF COMMODITIES
 
PROPOSAL 3.9:
 
IF THIS PROPOSAL IS APPROVED BY SHAREHOLDERS OF THE ADJUSTABLE RATE FUND, THE
ADJUSTABLE RATE FUND MAY NOT PURCHASE PHYSICAL COMMODITIES OR CONTRACTS RELATING
TO PHYSICAL COMMODITIES.
 
The Adjustable Rate Fund's current policies prohibit the purchase or sale of
commodities or commodity contracts. These policies may contain exceptions for
financial futures contracts and options on such contracts. Under the proposed
policy, the Adjustable Rate Fund would be prohibited from purchasing only
physical commodities or contracts relating to physical commodities.
 
LENDING
 
PROPOSAL 3.10:
 
IF THIS PROPOSAL IS APPROVED BY SHAREHOLDERS OF THE ADJUSTABLE RATE FUND, THE
ADJUSTABLE RATE FUND MAY NOT MAKE LOANS EXCEPT AS PERMITTED UNDER THE INVESTMENT
COMPANY ACT OF 1940, AS AMENDED, AND AS INTERPRETED OR MODIFIED BY REGULATORY
AUTHORITY HAVING JURISDICTION FROM TIME TO TIME.
 
The Adjustable Rate Fund's current lending policy prohibits making loans to
others except that the Adjustable Rate Fund may purchase debt obligations or
repurchase agreements and it may lend its portfolio securities in accordance
with its investment objective and policies. The proposed policy, unlike the
current policy, does not specify the particular types of lending in which the
Adjustable Rate Fund is permitted to engage; instead, the proposed policy
permits the Adjustable Rate Fund to lend in a manner
 
                                       31
<PAGE>   45
 
and to an extent permitted by applicable law. The proposed change would,
therefore, permit the Adjustable Rate Fund, subject to the receipt of any
necessary regulatory approval and Board authorization, to enter into lending
arrangements, including lending agreements under which the Adjustable Rate Fund
advised by Scudder Kemper could for temporary purposes lend money directly to
and borrow money directly from each other through a credit facility. The
Adjustable Rate Fund believes that the flexibility provided by this policy
change could possibly reduce the Adjustable Rate Fund's borrowing costs and
enhance its ability to earn higher rates of interest on short-term lendings in
the event that the Board determines that such arrangements are warranted in
light of the Adjustable Rate Fund's particular circumstances.
 
D. ELIMINATION OF SHAREHOLDER APPROVAL TO CHANGE OTHER FUNDAMENTAL POLICIES
 
Certain of the policies listed below (Margin Purchases and Short Sales, Assets,
Pledging of Assets and Purchases of Voting Securities) were initially adopted by
the Adjustable Rate Fund due to state securities law requirements that are no
longer in effect. Except as otherwise stated, if shareholders approve the
elimination of these policies as fundamental, management will recommend to the
Board that they eliminate these policies entirely as being unnecessary.
 
MARGIN PURCHASES AND SHORT SALES
 
PROPOSAL 3.11:
 
IF THIS PROPOSAL IS ADOPTED BY SHAREHOLDERS OF THE ADJUSTABLE RATE FUND, THE
ADJUSTABLE RATE FUND WILL NOT HAVE A FUNDAMENTAL RESTRICTION ON MARGIN PURCHASES
AND SHORT SALES.
 
The Adjustable Rate Fund is currently either prohibited from (1) making
purchases on margin and/or making short sales, unless the Adjustable Rate Fund
has the right to obtain securities equivalent in kind and amount to those sold
and unless not more than 10% of the Adjustable Rate Fund's total assets is held
as collateral for such sales at any one time, or (2) making margin purchases and
short sales, except to obtain short-term credits necessary for clearance of
transactions, and in the case of margin deposits, in connection with financial
futures and options transactions. If elimination of this restriction is approved
by shareholders, the Adjustable Rate Fund's potential use of margin transactions
beyond transactions in futures and options and for the clearance of purchases
and sales of securities, including the use of margin in ordinary securities
transactions, would be generally limited by the current position taken by the
staff of the SEC that margin transactions with respect to securities are
prohibited under Section 18 of the 1940 Act because they create senior
securities. "Margin transactions" involve the purchase of securities with money
borrowed from a broker, with cash or eligible securities being used as
collateral against the loan. The Adjustable Rate Fund's ability to engage in
margin transactions is also limited by its borrowing policies, which permit the
Adjustable Rate Fund to borrow money only as permitted by applicable law.
 
PLEDGING OF ASSETS
 
PROPOSAL 3.12:
 
IF THIS PROPOSAL IS ADOPTED BY SHAREHOLDERS OF THE ADJUSTABLE RATE FUND, THE
ADJUSTABLE RATE FUND WILL NOT HAVE A FUNDAMENTAL RESTRICTION ON PLEDGING OF
ASSETS.
 
The Adjustable Rate Fund is currently prohibited from pledging, mortgaging or
hypothecating more than 15% of its total assets and then only to secure
borrowings. The collateral arrangements with respect to options, financial
futures and delayed delivery transactions and any margin payments in connection
with such transactions are not deemed to be pledges or other encumbrances.
Management believes that, in the interest of simplicity, elimination of these
policies is appropriate and will provide the Adjustable Rate Fund with greater
operational flexibility.

PURCHASES OF SECURITIES
 
PROPOSAL 3.13:
 
IF THIS PROPOSAL IS ADOPTED BY SHAREHOLDERS OF THE ADJUSTABLE RATE FUND, THE
ADJUSTABLE RATE FUND WILL NOT HAVE A FUNDAMENTAL RESTRICTION ON PURCHASES OF
SECURITIES.
 
The Adjustable Rate Fund is prohibited with respect to 100% of its assets from
purchasing more than 10% of the securities of a single issuer. Additionally, the
Adjustable Rate Fund is a "diversified" Fund and is therefore limited to
purchasing, with respect to 75% of its assets, not more than 10% of the voting
securities of a single issuer.
 
PURCHASES OF OPTIONS AND WARRANTS
 
PROPOSAL 3.14:
 
IF THIS PROPOSAL IS ADOPTED BY SHAREHOLDERS OF THE ADJUSTABLE RATE FUND, THE
ADJUSTABLE RATE FUND WILL NOT HAVE A FUNDAMENTAL RESTRICTION ON PURCHASES OF
OPTIONS AND WARRANTS.
 
The Adjustable Rate Fund is currently prohibited from writing, purchasing or
selling options on more than 25% of Fund's net assets and is restricted from
investing more than 5% of the Fund's net assets on premiums on put and call
options except for purchases and sales of options on financial contracts.
Management believes that, in the interest of simplicity, the elimination of
these policies is appropriate and will provide the Adjustable Rate Fund with
greater investment flexibility.

B. SHAREHOLDER PROPOSALS
 
As a general matter, the Adjustable Rate Fund does not intend to hold future
regular annual or special meetings of its shareholders unless required by the
1940 Act. In the event the Reorganization is not consummated, the
Short-Intermediate Fund does not intend to hold future regular annual or special
meetings of its shareholders unless required by the 1940 Act. A shareholder
wishing to submit a proposal for inclusion in the Fund's proxy statement for the
next meeting of shareholders pursuant to Rule 14a-8 under the Securities
Exchange Act of 1934 should send such written proposal to the Secretary of the
Fund within a reasonable time before the solicitation of proxies for such
meeting. The timely submission of a proposal, however, does not guarantee its
inclusion. A shareholder wishing to provide notice in the manner prescribed by
Rule 14a-4(c)(1) to the Fund of a proposal submitted outside of the process of
Rule 14a-8 must submit such written notice to the Secretary of the Fund within a
reasonable time before the solicitation of proxies for such meeting. Timely
submission of a proposal does not necessarily mean that such proposal will be
included.

C. VOTING INFORMATION AND REQUIREMENTS
 
Holders of shares of the Short-Intermediate Fund are entitled to one vote per
share on matters as to which they are entitled to vote. The Short-Intermediate
Fund does not utilize cumulative voting. Holders of shares of the Adjustable
Rate Fund are entitled to one vote per share on matters as to which they are
entitled to vote. The Adjustable Rate Fund does not utilize cumulative voting.
 
Each valid proxy will be voted in accordance with the instructions on the proxy
and as the persons named in the proxy determine on such other business as may
come before the Special Meeting. If no instructions are given, the proxy will be
voted as recommended by the Board on each Proposal. Shareholders who execute
proxies may revoke them at any time before they are voted, either by writing to
the Funds or in person at the time of the Special Meeting. Proxies given by
telephone or electronically transmitted instruments may be counted if obtained
pursuant to procedures designed to verify that such instructions have been
authorized.
 
Proposal 1 (both Funds), approval of new investment management agreements, and
Proposal 3 (Adjustable Rate Fund only), approval of a new investment objective
and the revision of certain fundamental investment policies, require the
affirmative vote of a "majority of the outstanding voting securities", as
defined in the 1940 Act. The term "majority of the outstanding voting
securities" as defined in the 1940 Act means: the affirmative vote of the lesser
of (1) 67% of the voting securities of a Fund present at the meeting if more
than 50% of the outstanding voting securities of a fund are present in person or
by proxy or (2) more than 50% of the outstanding voting securities of a fund.
Proposal 2, approval of the Reorganization, requires the affirmative vote of a
majority of the outstanding shares of the Short-Intermediate Fund entitled to
vote. Approval of Proposal 2 by shareholders of the Short-Intermediate Fund is
conditional upon approval of Proposal 3 by shareholders of the Adjustable Rate
Fund.
 
In tallying shareholder votes, abstentions and broker non-votes (i.e., shares
held by brokers or nominees as to which (i) instructions have not been received
from the beneficial owners or persons entitled to vote and (ii) the broker or
nominee does not have discretionary voting power on a particular matter) will be
counted for determining whether a quorum is present for purposes of convening
the Special Meeting and will be considered present at the Special Meeting. On
Proposals 1 and 3, abstentions will have the effect of an "AGAINST" vote on each
Proposal. Broker non-votes will have the effect of an "AGAINST" vote on each
proposal if such vote is determined on the basis of obtaining the affirmative
vote of more than 50% of the outstanding voting securities. Broker non-votes
will not constitute "FOR" or "AGAINST" votes, and will be disregarded in
determining the voting securities "present" on each of these Proposals if such
vote is determined on the basis of the affirmative vote of 67% of the voting
securities of each of the Funds present at the Special Meeting. On Proposal 2,
abstentions and broker non-votes will have the effect of a "AGAINST" vote.
 
At least 30% of the shares of each Fund must be present, in person or by proxy,
in order to constitute a quorum. Thus the Special Meeting could not take place
on its scheduled date if less than 30% of the shares of each Fund were
presented. If, by the time scheduled for the meeting, a quorum of shareholders
of each Fund is not present or if a quorum is present but sufficient votes in
favor of any of the Proposals are not received, the persons named as proxies
currently intend to propose one or more adjournments of the meeting for the
Funds to permit further soliciting of proxies from shareholders. Any such
adjournment will require the affirmative vote of a majority of the shares of the
Funds present (in person or by proxy). The persons named as proxies will vote in
favor of any such adjournment if they determine that such adjournment and
additional solicitation are reasonable and in the interest of the Funds'
shareholders.
 
The cost of preparing, printing and mailing the enclosed proxy card and proxy
statement and all other costs incurred in connection with the solicitation of
proxies, including any additional solicitation made by letter, telephone or
telegraph, will be paid by Zurich or its affiliates. In addition to solicitation
by mail, certain officers and representatives of each Fund, officers and
employees of Scudder Kemper and certain financial services firms and their
representatives, who will receive no extra compensation for their services, may
solicit proxies by telephone, telegram or personally.

<PAGE>   49
 
Shareholder Communications Corporation ("SCC") has been engaged to assist in the
solicitation of proxies. As the Special Meeting date approaches, certain
shareholders of each Fund may receive a telephone call from a representative of
SCC if their votes have not yet been received. Authorization to permit SCC to
execute proxies may be obtained by telephonic or electronically transmitted
instructions from shareholders of each Fund. Proxies that are obtained
telephonically will be recorded in accordance with the procedures set forth
below. The Trustees believe that these procedures are reasonably designed to
ensure that the identity of the shareholder casting the vote is accurately
determined and that the voting instructions of the shareholder are accurately
determined.
 
In all cases where a telephonic proxy is solicited, the SCC representative is
required to ask for each shareholder's full name, address, social security or
employer identification number, title (if the shareholder is authorized to act
on behalf of an entity, such as a corporation), and the number of shares owned,
and to confirm that the shareholder has received the proxy materials in the
mail. If the information solicited agrees with the information provided to SCC,
then the SCC representative has the responsibility to explain the process, read
the Proposals on the proxy card, and ask for the shareholder's instructions on
the Proposals. The SCC representative, although he or she is permitted to answer
questions about the process, is not permitted to recommend to the shareholder
how to vote, other than to read any recommendation set forth in the proxy
statement. SCC will record the shareholder's instructions on the card. Within 72
hours, the shareholder will be sent a letter or mailgram to confirm his or her
vote and asking the shareholder to call SCC immediately if his or her
instructions are not correctly reflected in the confirmation.
 
If a shareholder wishes to participate in the Special Meeting, but does not wish
to give a proxy by telephone, the shareholder may still submit the proxy card
originally sent with the proxy statement or attend in person. Should
shareholders required additional information regarding the proxy or replacement
proxy cards, they may contact SCC toll-free at 1-800-733-8481, ext. 429. Any
proxy given by a shareholder, whether in writing or by telephone, is revocable
until voted at the Special Meeting.
 
THE BOARD OF DIRECTORS OF EACH FUND RECOMMENDS THAT SHAREHOLDERS VOTE "FOR" ALL
PROPOSALS FOR WHICH THEY ARE ENTITLED TO VOTE.
 
               , 1998
 
                  PLEASE SIGN AND RETURN YOUR PROXY PROMPTLY.
 
                 YOUR VOTE IS IMPORTANT AND YOUR PARTICIPATION
              IN THE AFFAIRS OF YOUR FUND DOES MAKE A DIFFERENCE.

                        INVESTMENT MANAGEMENT AGREEMENT
 
Ladies and Gentlemen:
 
     [Name of Fund] (the "Fund") has been established as a Massachusetts
business trust to engage in the business of an investment company. The Fund has
issued shares of beneficial interest (the "Shares").
 
     The Fund has selected you to act as the investment manager of the Fund and
to provide certain other services, as more fully set forth below, and you have
indicated that you are willing to act as such investment manager and to perform
such services under the terms and conditions hereinafter set forth. Accordingly,
the Fund agrees with you as follows:
 
          1.  Delivery of Documents.  The Fund engages in the business of
     investing and reinvesting its assets in the manner and in accordance with
     its investment objectives, policies and restrictions. The Fund has
     furnished you with copies properly certified or authenticated of each of
     the following documents related to the Fund:
 
             (a) The Declaration of Trust ("Declaration"), as amended to date.
 
             (b) By-Laws of the Fund as in effect on the date hereof (the "By-
        Laws").
 
             (c) Resolutions of the Trustees of the Fund and the shareholders of
        the Fund selecting you as investment manager and approving the form of
        this Agreement.
 
          The Fund will furnish you from time to time with copies, properly
     certified or authenticated, of all amendments of or supplements, if any, to
     the foregoing.
 
          2.  Portfolio Management Services.  As manager of the assets of the
     Fund, you shall provide continuing investment management of the assets of
     the Fund in accordance with its investment objectives, policies and
     restrictions;
 
                                       A-1
<PAGE>   51
 
     the applicable provisions of the Investment Company Act of 1940 (the "1940
     Act") and the Internal Revenue Code of 1986, as amended, (the "Code")
     relating to regulated investment companies and all rules and regulations
     thereunder; and all other applicable federal and state laws and regulations
     of which you have knowledge; subject always to policies and instructions
     adopted by the Fund's Board of Trustees. In connection therewith, you shall
     use reasonable efforts to manage the Fund so that it will qualify as a
     regulated investment company under Subchapter M of the Code and regulations
     issued thereunder. The Fund shall have the benefit of the investment
     analysis and research, the review of current economic conditions and trends
     and the consideration of long-range investment policy generally available
     to your investment advisory clients. In managing the Fund in accordance
     with the requirements set forth in this section 2, you shall be entitled to
     receive and act upon advice of counsel to the Fund. You shall also make
     available to the Fund promptly upon request all of the Fund's investment
     records and ledgers as are necessary to assist the Fund in complying with
     the requirements of the 1940 Act and other applicable laws. To the extent
     required by law, you shall furnish to regulatory authorities having the
     requisite authority any information or reports in connection with the
     services provided pursuant to this Agreement which may be requested in
     order to ascertain whether the operations of the Fund are being conducted
     in a manner consistent with applicable laws and regulations.
 
          You shall determine the securities, instruments, investments,
     currencies, repurchase agreements, futures, options and other contracts
     relating to investments to be purchased, sold or entered into by the Fund
     and place orders with broker-dealers, foreign currency dealers, futures
     commission merchants or others pursuant to your determinations and all in
     accordance with Fund policies. You shall determine what portion of the
     Fund's portfolio shall be invested in securities and other assets and what
     portion, if any, should be held uninvested.
 
          You shall furnish to the Fund's Board of Trustees periodic reports on
     the investment performance of the Fund and on the performance of your
     obligations pursuant to this Agreement, and you shall supply such
     additional reports and information as the Fund's officers or Board of
     Trustees shall reasonably request.
 
          3.  Administrative Services.  In addition to the portfolio management
     services specified above in section 2, you shall furnish at your expense
     for the use of the Fund such office space and facilities in the United
     States as the Fund may require for its reasonable needs, and you (or one or
     more of your affiliates designated by you) shall render to the Fund
     administrative services on behalf of the Fund necessary for operating as a
     closed-end investment company and not provided by persons not parties to
     this Agreement including, but not limited to, preparing reports to and
     meeting materials for the Fund's Board of Trustees and reports and notices

     the Fund's business, subject to the direction and control of the Fund's

     you or to diminish the obligations of any agent of the Fund or any other
     person not a party to this Agreement which is obligated to provide services
     to the Fund.
 
          4.  Allocation of Charges and Expenses.  Except as otherwise
     specifically provided in this section 4, you shall pay the compensation and
     expenses of all Trustees, officers and executive employees of the Fund
     (including the Fund's share of payroll taxes) who are affiliated persons of
     you, and you shall make available, without expense to the Fund, the
     services of such of your directors, officers and employees as may duly be
     elected officers of the Fund, subject to their individual consent to serve
     and
 
                                       A-3
<PAGE>   53
 
     to any limitations imposed by law. You shall provide at your expense the
     portfolio management services described in section 2 hereof and the
     administrative services described in section 3 hereof.
 
          You shall not be required to pay any expenses of the Fund other than
     those specifically allocated to you in this section 4. In particular, but
     without limiting the generality of the foregoing, you shall not be
     responsible, except to the extent of the reasonable compensation of such of
     the Fund's Trustees and officers as are directors, officers or employees of
     you whose services may be involved, for the following expenses of the Fund:
     organization expenses of the Fund (including out of-pocket expenses, but
     not including your overhead or employee costs); fees payable to you and to
     any other Fund advisors or consultants; legal expenses; auditing and
     accounting expenses; maintenance of books and records which are required to
     be maintained by the Fund's custodian or other agents of the Fund;
     telephone, telex, facsimile, postage and other communications expenses;

     in connection with membership in investment company trade organizations;
     fees and expenses of the Fund's accounting agent for which the Fund is
     responsible pursuant to the terms of the Fund Accounting Services
     Agreement, custodians, subcustodians, transfer agents, dividend disbursing
     agents and registrars; payment for portfolio pricing or valuation services
     to pricing agents, accountants, bankers and other specialists, if any;
     expenses of preparing share certificates and, except as provided below in
     this section 4, other expenses in connection with the issuance, offering,
     distribution, sale, redemption or repurchase of securities issued by the
     Fund; expenses relating to investor and public relations; expenses and fees
     of registering or qualifying Shares of the Fund for sale; interest charges,
     bond premiums and other insurance expense; freight, insurance and other
     charges in connection with the shipment of the Fund's portfolio securities;
     the compensation and all expenses (specifically including travel expenses
     relating to Fund business) of Trustees, officers and employees of the Fund
     who are not affiliated persons of you; brokerage commissions or other costs
     of acquiring or disposing of any portfolio securities of the Fund; expenses
     of printing and distributing reports, notices and dividends to
     shareholders; expenses of printing and mailing Prospectuses and statements
     of additional information of the Fund and supplements thereto; costs of
     stationery; any litigation expenses; indemnification of Trustees and
     officers of the Fund; and costs of shareholders' and other meetings.
 
          5.  Management Fee.  For all services to be rendered, payments to be
     made and costs to be assumed by you as provided in sections 2, 3, and 4
     hereof, the Fund shall pay you in United States Dollars on the last day of
     each month the unpaid balance of a fee equal to the excess of (a) 1/12 of [
     ] of 1 percent of the average weekly net assets of the Fund for such month;
     over (b) any compensation waived by you from time to time (as more fully
     described below). You shall be entitled to receive during any
                                       A-4
<PAGE>   54
 
     month such interim payments of your fee hereunder as you shall request,
     provided that no such payment shall exceed 75 percent of the amount of your
     fee then accrued on the books of the Fund and unpaid.
 
          The net asset value of the Fund shall be calculated at such time or
     times as the Trustees may determine in accordance with the provisions of
     the 1940 Act. On each day when net asset value is not calculated, the net
     asset value shall be deemed to be the net asset value as of the close of
     business on the last day on which such calculation was made for the purpose
     of the foregoing computations.
 
          You may waive all or a portion of your fees provided for hereunder and
     such waiver shall be treated as a reduction in purchase price of your
     services. You shall be contractually bound hereunder by the terms of any
     publicly announced waiver of your fee, or any limitation of the Fund's
     expenses, as if such waiver or limitation were fully set forth herein.
 
          6.  Avoidance of Inconsistent Position; Services Not Exclusive.  In
     connection with purchases or sales of portfolio securities and other
     investments for the account of the Fund, neither you nor any of your
     directors, officers or employees shall act as a principal or agent or
     receive any commission. You or your agent shall arrange for the placing of
     all orders for the purchase and sale of portfolio securities and other
     investments for the Fund's account with brokers or dealers selected by you
     in accordance with Fund policies. If any occasion should arise in which you
     give any advice to clients of yours concerning the Shares of the Fund, you
     shall act solely as investment counsel for such clients and not in any way
     on behalf of the Fund.
 
          Your services to the Fund pursuant to this Agreement are not to be
     deemed to be exclusive and it is understood that you may render investment
     advice, management and services to others. In acting under this Agreement,
     you shall be an independent contractor and not an agent of the Fund.
     Whenever the Fund and one or more other accounts or investment companies
     advised by you have available funds for investment, investments suitable
     and appropriate for each shall be allocated in accordance with procedures
     believed by you to be equitable to each entity. Similarly, opportunities to
     sell securities shall be allocated in a manner believed by you to be
     equitable. The Fund recognizes that in some cases this procedure may
     adversely affect the size of the position that may be acquired or disposed
     of for the Fund.
 
          7.  Limitation of Liability of Manager.  As an inducement to your
     undertaking to render services pursuant to this Agreement, the Fund agrees
     that you shall not be liable under this Agreement for any error of judgment
     or mistake of law or for any loss suffered by the Fund in connection with
     the matters to which this Agreement relates, provided that nothing in this
     Agreement shall be deemed to protect or purport to protect you against any
     liability to the Fund or its shareholders to which you would otherwise be
 
                                       A-5
<PAGE>   55
 
     subject by reason of willful misfeasance, bad faith or gross negligence in
     the performance of your duties, or by reason of your reckless disregard of
     your obligations and duties hereunder.
 
          8.  Duration and Termination of This Agreement.  This Agreement shall
     remain in force until September 30, 1999, and continue in force from year
     to year thereafter, but only so long as such continuance is specifically
     approved at least annually (a) by the vote of a majority of the Trustees
     who are not parties to this Agreement or interested persons of any party to
     this Agreement, cast in person at a meeting called for the purpose of
     voting on such approval, and (b) by the Trustees of the Fund, or by the
     vote of a majority of the outstanding voting securities of the Fund. The
     aforesaid 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 and any applicable
     SEC exemptive order therefrom.
 
          This Agreement may be terminated with respect to the Fund at any time,
     without the payment of any penalty, by the vote of a majority of the
     outstanding voting securities of the Fund or by the Fund's Board of
     Trustees on 60 days' written notice to you, or by you on 60 days' written
     notice to the Fund. This Agreement shall terminate automatically in the
     event of its assignment.
 
          This Agreement may be terminated with respect to the Fund at any time
     without the payment of any penalty by the Board of Trustees or by vote of a
     majority of the outstanding voting securities of the Fund in the event that
     it shall have been established by a court of competent jurisdiction that
     you or any of your officers or directors has taken any action which results
     in a breach of your covenants set forth herein.
 
          9.  Amendment of this Agreement.  No provision of this Agreement may
     be changed, waived, discharged or terminated orally, but only by an
     instrument in writing signed by the party against whom enforcement of the
     change, waiver, discharge or termination is sought, and no amendment of
     this Agreement shall be effective until approved in a manner consistent
     with the 1940 Act and rules and regulations thereunder and any applicable
     SEC exemptive order therefrom.
 
          10.  Limitation of Liability for Claims.  The Declaration, a copy of
     which, together with all amendments thereto, is on file in the Office of
     the Secretary of the Commonwealth of Massachusetts, provides that the name
     "[name of Fund]" refers to the Trustees under the Declaration collectively
     as Trustees and not as individuals or personally, and that no shareholder
     of the Fund, or Trustee, officer, employee or agent of the Fund, shall be
     subject to claims against or obligations of the Fund to any extent
     whatsoever, but that the Fund estate only shall be liable.
 
                                       A-6
<PAGE>   56

 
          You are hereby expressly put on notice of the limitation of liability
     as set forth in the Declaration and you agree that the obligations assumed
     by the Fund pursuant to this Agreement shall be limited in all cases to the
     Fund and its assets, and you shall not seek satisfaction of any such
     obligation from the shareholders or any shareholder of the Fund, or from
     any Trustee, officer, employee or agent of the Fund.
 
          11.  Miscellaneous.  The captions in this Agreement are included for
     convenience of reference only and in no way define or limit any of the
     provisions hereof or otherwise affect their construction or effect. This
     Agreement may be executed simultaneously in two or more counterparts, each
     of which shall be deemed an original, but all of which together shall
     constitute one and the same instrument.
 
          In interpreting the provisions of this Agreement, the definitions
     contained in Section 2(a) of the 1940 Act (particularly the definitions of
     "affiliated person," "assignment" and "majority of the outstanding voting
     securities"), as from time to time amended, shall be applied, subject,
     however, to such exemptions as may be granted by the SEC by any rule,
     regulation or order.
 
          This Agreement shall be construed in accordance with the laws of the
     Commonwealth of Massachusetts, provided that nothing herein shall be
     construed in a manner inconsistent with the 1940 Act, or in a manner which
     would cause the Fund to fail to comply with the requirements of Subchapter
     M of the Code.
 
          This Agreement shall supersede all prior investment advisory or
     management agreements entered into between you and the Fund.
 
          If you are in agreement with the foregoing, please execute the form of
     acceptance on the accompanying counterpart of this letter and return such
     counterpart to the Fund, whereupon this letter shall become a binding
     contract effective as of the date of this Agreement.
 
                                Yours very truly,
 
                                [Name of Fund]

NOTES: Scudder Kemper agreed to waive its management fee and absorb certain
operating expenses during a portion of the fiscal year ended August 31, 1992.
Thereafter, these expenses were gradually reinstated from December 31, 1992
through January 31, 1994. Without this agreement, the ratios of expenses and net
investment income to average net assets for Class A shares would have been .99%
and 3.90% for the year ended August 31, 1994.
 
Total return does not reflect the effect of any sales charges.

                  ADJUSTABLE RATE FUND'S FUNDAMENTAL POLICIES
 
THE ADJUSTABLE RATE FUND MAY NOT, AS A FUNDAMENTAL POLICY:
 
(1) Purchase securities of any issuer (other than obligations of, or guaranteed
by, the U.S. Government, its agencies or instrumentalities) if, as a result,
more than 5% of the total value of the Fund's assets would be invested in
securities of that issuer.
 
(2) Purchase more than 10% of any class of voting securities of any issuer.
 
(3) Make loans to others provided that the Fund may purchase debt obligations or
repurchase agreements and it may lend its securities in accordance with its
investment objective and policies.
 
(4) Borrow money except as a temporary measure for extraordinary or emergency
purposes, and then only in an amount up to one-third of the value of its total
assets, in order to meet redemption requests without immediately selling any
portfolio securities. If, for any reason, the current value of the Fund's total
assets falls below an amount equal to three times the amount of its indebtedness
from money borrowed, the Fund will, within three days (not including Sundays and
holidays), reduce its indebtedness to the extent necessary. The Fund will not
borrow for leverage purposes and will not purchase securities or make
investments while borrowings are outstanding.
 
(5) Pledge, hypothecate, mortgage or otherwise encumber more than 15% of its
total assets and then only to secure borrowings permitted by restriction 4
above. (The collateral arrangements with respect to options, financial futures

prospectus.
 
PURCHASE OF SHARES
 
Effective June 30, 1998, the net asset value transfer privilege is eliminated.
The net asset value transfer privilege provides for the purchase of Class A
shares at net asset value to the extent the amount invested represents the net
proceeds from a redemption of shares of a mutual fund that Scudder Kemper
Investments, Inc. or an affiliate does not serve as investment manager provided
that: (a) the investor has previously paid either an initial sales charge in
connection with the purchase of the non-Kemper Fund shares redeemed or a
contingent deferred sales charge in connection with the redemption of the
non-Kemper Fund shares, and (b) the purchase of Fund shares is made within 90
days after the date of such redemption.
 
REDEMPTION OR REPURCHASE OF SHARES -- CONTINGENT DEFERRED SALES CHARGE -- CLASS

The waiver of the contingent deferred sales charge for Class C shares has been
expanded to include the following exception.
 
     Redemption of shares purchased through a dealer-sponsored asset allocation
     program maintained on an omnibus record-keeping system provided the dealer
     of record had waived the advance of the first year administrative services
     and distribution fees applicable to such shares and has agreed to receive
     such fees quarterly.

INVESTMENT MANAGER AND UNDERWRITER
 
Pursuant to the terms of an agreement, Zurich Insurance Company ("Zurich"), the
parent of the Funds' investment adviser, Zurich Kemper Investments, Inc. ("ZKI")
and Scudder, Stevens & Clark, Inc. ("Scudder") have formed a new global
investment organization by combining Scudder's business with that of ZKI, and
Scudder has changed its name to Scudder Kemper Investments, Inc. ("Scudder
Kemper"). As a result of the transaction, Zurich owns approximately 70% of
Scudder Kemper, with the balance owned by Scudder Kemper's officers and
employees. Scudder Kemper, 280 Park Avenue, 40th floor, New York, New York
10017, now manages in excess of $200 billion.
 
Because the transaction between Scudder and Zurich resulted in the assignment of
each Fund's investment management agreement between ZKI and each respective
Fund, each of those agreements was deemed to be automatically terminated upon
consummation of the transaction. In anticipation of the transaction, however,
new investment management agreements between each Fund and Scudder Kemper were
approved
<PAGE>   70
 
by each respective Fund's Board of Trustees. A special meeting of shareholders
(the "Special Meeting") of each Fund was held in December, 1997, at which time
the shareholders also approved the new investment management agreements. The new
investment management agreements (each an "Investment Management Agreement" and,
collectively, the "Investment Management Agreements") are all effective as of
December 31, 1997 and will be in effect for an initial term ending on the same
date as would the corresponding previous investment management agreement.
 
Each Fund's Investment Management Agreement is substantially similar to the
corresponding investment management agreement terminated by the transaction,
except that Scudder Kemper is the new investment adviser to each Fund, the
management fee (except with respect to Kemper Small Capitalization Equity Fund
and Kemper Aggressive Growth Fund) is calculated monthly at 1/12 of the
applicable annual rate based upon the average daily net assets for such month,
and, for each Fund except Kemper Municipal Bond Fund, Kemper U.S. Government
Securities Fund and Kemper California Tax-Free Income Fund, the expense
limitation has been deleted because there are no longer any state expense
limitations in effect. In addition, for Funds investing in foreign securities,
except for Kemper International Fund, Kemper Global Income Fund, and Kemper
Asian Growth Fund, each Fund's respective sub-advisory agreement with Zurich
Investment Management Limited ("ZIML") has been terminated and Scudder Kemper
has assumed the duties previously performed by ZIML under each such Fund's
respective sub-advisory agreement. For Kemper Value Plus Growth Fund, the Fund's
sub-advisory agreement with Zurich Kemper Value Advisors, Inc. ("ZKVA") has been
terminated and Scudder Kemper has assumed the duties previously performed by
ZKVA under the Fund's sub-advisory agreement.
 
In addition, under a separate agreement between each Fund and Scudder Fund
Accounting Corporation ("SFAC"), a subsidiary of Scudder Kemper, SFAC, rather
than each Fund's investment manager, will compute the net asset value for each
Fund. SFAC does not charge the Funds for this service; however, subject to Board
approval, at some time in the future, SFAC may seek payment for its services
under this agreement.
 
CAPITAL STRUCTURE
 
Pending shareholder approval, except for Kemper Technology Fund, Kemper U.S.
Government Securities Fund, Kemper High Yield Opportunity Fund, Kemper Municipal
Bond Fund, Kemper California Tax-Free Income Fund, Kemper Florida Tax-Free
Income Fund, Kemper Michigan Tax-Free Income Fund, Kemper New Jersey Tax-Free
Income Fund, Kemper New York Tax-Free Income Fund, Kemper Ohio Tax-Free Income
Fund, and Kemper Pennsylvania Tax-Free Income Fund, which have obtained
shareholder approval, rather than invest in securities directly, each of the
Funds may in the future seek to achieve its investment objective by pooling its
assets with assets of other mutual funds for investment in another investment
company having the same investment objective and substantially the same
investment policies and restrictions as such Fund. The purpose of such an
arrangement is to achieve greater operational efficiencies and to reduce costs.
It is expected that any such investment company will be managed by Scudder
Kemper in substantially the same manner as the corresponding Fund. Shareholders
of each Fund will be given at least 30 days' prior notice of any such
investment, although they will not be entitled to vote on the action. Such
investment would be made only if the Trustees determine it to be in the best
interests of the respective Fund and its shareholders.

The following disclosure replaces the "Net Asset Value" section of each
Prospectus except the Kemper Equity Funds/Value Style Prospectus. The following
effective dates apply: June 1998 for Kemper Aggressive Growth Fund, Kemper Blue
Chip Fund, Kemper Target Equity Fund -- Kemper Retirement Fund Series VII and
Kemper Total Return Fund; and July 1998 for Kemper Asian Growth Fund. The
following disclosure will be effective prior to the close of the third calendar
quarter of 1998 for the remainder of the Funds.
 
     NET ASSET VALUE
 
     The net asset value per share of a Fund is the value of one share and is
     determined separately for each class by dividing the value of a Fund's net
     assets attributable to the class by the number of shares of that class
     outstanding. The per share net asset value of each of Class B and Class C
     shares of the Fund will generally be lower than that of the Class A shares
     of a Fund because of the higher expenses borne by the Class B and Class C
     shares. The net asset value of shares of a Fund is computed as of the close
     of regular trading (the "value time") on the New York Stock Exchange (the
     "Exchange") on each day the Exchange is open for trading. The Exchange is
     scheduled to be closed on the following holidays: New Year's Day, Martin
     Luther King, Jr. Day, Presidents' Day, Good Friday, Memorial Day,
     Independence Day, Labor Day, Thanksgiving and Christmas.
 
     Portfolio securities for which market quotations are readily available are
     generally valued at market value as of the value time in the manner
     described below. All other securities may be valued at fair value as
     determined in good faith by or under the direction of the Board.
 
     With respect to the Funds with securities listed primarily on foreign
     exchanges, such securities may trade on days when the Fund's net asset
     value is not computed; and therefore, the net asset value of a Fund may be
     significantly affected on days when the investor has no access to the Fund.
 
     An exchange-traded equity security is valued at its most recent sale price.
     Lacking any sales, the security is valued at the calculated mean between
     the most recent bid quotation and the most recent asked quotation (the
     "Calculated Mean"). Lacking a Calculated Mean, the security is valued at
     the most recent bid quotation. An equity security which is traded on The
     Nasdaq Stock Market Inc. ("Nasdaq") is valued at its most recent sale
     price. Lacking any sales, the security is valued at the most recent bid
     quotation. The value of an equity security not quoted on Nasdaq, but traded
     in another over-the-counter market, is its most recent sale price. Lacking
     any sales, the security is valued at the Calculated Mean. Lacking a
     Calculated Mean, the security is valued at the most recent bid quotation.
 
     Debt securities are valued at prices supplied by a pricing agent(s) which
     reflect broker/dealer supplied valuations and electronic data processing
     techniques. Money market instruments purchased with an original maturity of
     sixty days or less, maturing at par, shall be valued at amortized cost,
     which the Board believes approximates market value. If it is not possible
     to value a particular debt security pursuant to these valuation methods,
     the
<PAGE>   75
 
     value of such security is the most recent bid quotation supplied by a bona
     fide marketmaker. If it is not possible to value a particular debt security
     pursuant to the above methods, the investment manager of the particular
     fund may calculate the price of that debt security, subject to limitations
     established by the Board.
 
     An exchange-traded options contract on securities, currencies, futures and
     other financial instruments is valued at its most recent sale price on such
     exchange. Lacking any sales, the options contract is valued at the
     Calculated Mean. Lacking any Calculated Mean, the options contract is
     valued at the most recent bid quotation in the case of a purchased options
     contract, or the most recent asked quotation in the case of a written
     options contract. An options contract on securities, currencies and other
     financial instruments traded over-the-counter is valued at the most recent
     bid quotation in the case of a purchased options contract and at the most
     recent asked quotation in the case of a written options contract. Futures
     contracts are valued at the most recent settlement price. Foreign currency
     exchange forward contracts are valued at the value of the underlying
     currency at the prevailing exchange rate on the valuation date.
 
     If a security is traded on more than one exchange, or upon one or more
     exchanges and in the over-the-counter market, quotations are taken from the
     market in which the security is traded most extensively.
 
     If, in the opinion of the Valuation Committee of the Board of Trustees, the
     value of a portfolio asset as determined in accordance with these
     procedures does not represent the fair market value of the portfolio asset,
     the value of the portfolio asset is taken to be an amount which, in the
     opinion of the Valuation Committee, represents fair market value on the
     basis of all available information. The value of other portfolio holdings
     owned by a Fund is determined in a manner which, in the discretion of the
     Valuation Committee, most fairly reflects market value of the property on
     the valuation date.
 
     Following the valuations of securities or other portfolios assets in terms
     of the currency in which the market quotation used is expressed ("Local
     Currency"), the value of these portfolio assets in terms of U.S. dollars is
     calculated by converting the Local Currency into U.S. dollars at the
     prevailing currency exchange rate on the valuation date.

Manager and Underwriter" on page 23 in the Prospectus dated March 1, 1998 for
Kemper Asian Growth Fund, Kemper Europe Fund, Kemper Global Income Fund and
Kemper International Fund.
 
     INVESTMENT MANAGER AND UNDERWRITER
 
     Zurich Investment Management Limited ("ZIML") has been serving as
     sub-adviser for the Kemper Asian Growth Fund, Kemper Europe Fund, Kemper
     Global Income Fund and Kemper International Fund pursuant to sub-advisory
     agreements with Scudder Kemper Investments, Inc. ("Scudder
<PAGE>   76
 
     Kemper"), the Funds' investment manager. ZIML, which was previously a
     wholly owned subsidiary of Zurich Insurance Company, is now a wholly owned
     subsidiary of Scudder Kemper and is now known as Scudder Investments (U.K.)
     Limited (the "Sub-Adviser"). As a result of this ownership change, for
     Kemper Europe Fund, Kemper Global Income Fund and Kemper International
     Fund, new sub-advisory agreements, which were previously approved by
     shareholders, have been entered into between Scudder Kemper and the
     Sub-Adviser on the same terms as the previous agreements, which terminated
     automatically. The sub-advisory agreement for Kemper Asian Growth Fund also
     terminated automatically upon this ownership change but a new agreement has
     not been implemented for that Fund, which will be managed solely by Scudder
     Kemper.
 
The following text replaces information in the section entitled "Investment
Manager and Underwriter" on page 23 in the Prospectus dated March 1, 1998 for
Kemper Asian Growth Fund, Kemper Europe Fund, Kemper Global Income Fund and
Kemper International Fund.
 
     Stephen P. Dexter and Marc. J. Slendebroek have been the co-lead portfolio
     managers for the Kemper International Fund since June 1998. Mr. Dexter
     joined Scudder Kemper in 1986 and is a Senior Vice President. He received a
     B.A. in Economics and an M.B.A. in Finance from the University of
     Wisconsin. Mr. Slendebroek joined the Sub-Adviser in September 1994 and is

The following text replaces the section and heading entitled "Investment
Objectives, Policies and Risk Factors -- Depository Receipts" on page 20 in the
Prospectus dated May 6, 1998 for Kemper Contrarian Fund, Kemper-Dreman High
Return Equity Fund, Kemper Small Cap Value Fund, and Kemper Small Cap Relative
Value Fund:
 
     FOREIGN COMPANIES
 
     Each Fund may invest up to 20% of its assets in securities of foreign
     companies through the acquisition of American Depository Receipts ("ADRs"),
     as well as through the purchase of securities of foreign companies that are
     publicly traded in the United States. ADRs are bought
<PAGE>   77
 
     and sold in the United States and are issued by domestic banks. ADRs
     represent the right to receive securities of foreign issuers deposited in
     the domestic bank or a correspondent bank. ADRs do not eliminate all of the
     risk inherent in investing in the securities of foreign issuers, such as
     changes in foreign currency exchange rates. However, by investing in ADRs
     rather than directly in foreign issuers' stock, the Fund avoids currency
     risks during the settlement period. In general, there is a large, liquid
     market in the United States for most ADRs.
 
The following text replaces the third paragraph in the section entitled
"Investment Objectives, Policies and Risk Factors -- Selection of Investments"
on page 11 in the Prospectus dated April 1, 1998 for Kemper Contrarian Fund,
Kemper-Dreman High Return Equity Fund, and Kemper Small Cap Value Fund:
 
     SELECTION OF INVESTMENTS
 
     Fundamental analysis is used on companies that initially look promising.
     Earnings and cash flow analysis as well as a company's conventional
     dividend payout ratio are important to this process. Typically, the Funds
     will consist of approximately 25 to 50 stocks, diversified by both sector
     and industry, although, as noted above, the High Return Equity Fund may,
     from time to time, concentrate its assets in one or more market sectors.
     Most investments will be in securities of domestic companies, but, the
     Funds may also invest up to 20% of their assets in securities of foreign
     companies through the acquisition of American Depository Receipts ("ADRs")
     as well as through the purchase of securities of foreign companies that are
     publicly traded in the United States. ADRs are receipts issued by a U.S.
     bank or trust company evidencing ownership of underlying securities issued
     by a foreign issuer. ADRs may be listed on a national securities exchange
     or may be traded in the over-the-counter market. While it is anticipated
     that under normal circumstances all Funds will be fully invested, in order
     to conserve assets during temporary defensive periods when the investment
     manager deems it appropriate, each Fund may invest up to 50% of its assets
     in cash or defensive-type securities, such as high-grade debt securities,
     securities of the U.S. Government or its agencies and high quality money
     market instruments, including repurchase agreements. Investments in such
     interest bearing securities will be for temporary defensive purposes only.
 
The following text replaces the third and fourth paragraphs in the section
entitled "Investment Objectives, Policies and Risk Factors -- Kemper
Value+Growth Fund" on page 21 in the Prospectus dated February 1, 1998 for
Kemper Value+Growth Fund:
 
     VALUE+GROWTH FUND
 
     The allocation between growth and value stocks in the Fund's portfolio will
     be made by the investment manager's Quantitative Research Department with
     the help of a proprietary model that evaluates macro-economic factors such
     as the strength of the economy, interest rates and special factors
     concerning growth and value stocks. Historically, the performance
<PAGE>   78
 
     of growth and value stocks has tended to be counter-cyclical, i.e., when
     one was in favor, the other was out of favor relative to the equity market
     in general. Through the allocation process, the investment manager will
     seek to weight the portfolio more heavily in the type of stocks that are
     believed to present greater return opportunities at the time. The neutral
     allocation between growth and value stocks would be 50%/50%. The allocation
     to growth or value may be up to 75% at any time. Allocation decisions are
     normally based upon long-term considerations and changes would normally be
     expected to be gradual. There is no assurance that the allocation process
     will improve investment results.
 
     In managing both the growth and value portions of the portfolio, the
     investment manager emphasizes stock selection and fundamental research in
     seeking to enhance long-term performance potential. The investment manager
     considers a number of qualitative and quantitative factors in considering
     whether to invest in a growth or value stock including return on equity,
     earnings growth, price to earnings, price to book value and price to cash
     flow ratios, dividend yield, level of debt, good management and industry
     leadership. Typically stocks of both types will have a market
     capitalization in excess of $1 billion.

     INVESTMENT MANAGER AND UNDERWRITER
 
     Philip S. Fortuna is the lead portfolio manager for the Kemper Horizon
     Fund, Kemper Value+Growth Fund, and Kemper Quantitative Equity Fund. Mr.
     Fortuna joined Scudder Kemper in 1986 and is a Managing Director. He served
     as Director of Quantitative Services from 1987 to 1993 and Director of
     Investment Operations from 1993 to 1995. From 1995 to 1997, he was involved
     in global planning and new product development in addition to his portfolio
     management responsibilities. Mr. Fortuna currently oversees all of Scudder
     Kemper's quantitative activities.

On December 22, 1997, Zurich Insurance Company ("Zurich") entered into an
agreement with B.A.T. Industries p.l.c. ("B.A.T") pursuant to which the
financial services businesses of B.A.T will be combined with Zurich's businesses
(including Zurich's 70% interest in Scudder Kemper Investments, Inc. ("Scudder
Kemper")) to form a new global insurance and financial services company known as
Zurich Financial Services. After the transaction is completed, by way of a dual
holding company structure, current Zurich shareholders will own approximately
57% of the new organization, with the balance owned by B.A.T's current
shareholders.
 
The transaction is expected to close in the third quarter of 1998. Upon
consummation of the transaction, each Fund's investment management agreement
with Scudder Kemper will be deemed to have been assigned and, therefore, will
terminate. Each Board has approved new investment management agreements with
Scudder Kemper, which are substantially identical to the current investment
management agreements, except for the dates of execution and termination. Each
new investment management agreement is to become effective upon the termination
of the current investment management agreement. Each Board will seek shareholder
approval of the new investment management agreements through a proxy
solicitation that is currently scheduled to conclude in mid-December.

SUMMARY
 
INVESTMENT OBJECTIVES. The eight open-end, diversified, management investment
companies or portfolios thereof (the "Funds") covered in this combined
prospectus are as follows:
 
KEMPER ADJUSTABLE RATE U.S. GOVERNMENT FUND (the "Adjustable Rate Fund") seeks
high current income consistent with low volatility of principal.
 
KEMPER DIVERSIFIED INCOME FUND (the "Diversified Fund") seeks a high current
return.
 
KEMPER U.S. GOVERNMENT SECURITIES FUND (the "Government Fund") seeks high
current income, liquidity and security of principal.
 
KEMPER HIGH YIELD FUND (the "High Yield Fund") seeks the highest level of
current income obtainable from a professionally managed, diversified portfolio
of fixed income securities which the Fund's investment manager considers
consistent with reasonable risk.
 
KEMPER HIGH YIELD OPPORTUNITY FUND (the "Opportunity Fund") seeks total return
through high current income and capital appreciation.
 
KEMPER INCOME AND CAPITAL PRESERVATION FUND (the "Income and Capital Fund")
seeks as high a level of current income as is consistent with prudent investment
management, preservation of capital and ready marketability of its portfolio.
 
KEMPER U.S. MORTGAGE FUND (the "Mortgage Fund") seeks maximum current return
from U.S. Government securities.
 
KEMPER SHORT-INTERMEDIATE GOVERNMENT FUND (the "Short-Intermediate Government
Fund") seeks, with equal emphasis, high current income and preservation of
capital from a portfolio composed primarily of short and intermediate-term U.S.
Government securities.
 
Each Fund may engage in options and financial futures transactions. The
Diversified, High Yield, Income and Capital and Opportunity Funds each may
invest a portion of its assets in foreign securities and engage in related
foreign currency transactions. See "Investment Objectives, Policies and Risk
Factors."
 
RISK FACTORS. There is no assurance that the investment objective of any Fund
will be achieved and investment in each Fund includes risks that vary in kind
and degree depending upon the investment policies of that Fund. The returns and
net asset value of each Fund will fluctuate. Investors should note that
investments in high yield securities by certain Funds (principally the
Diversified, High Yield and Opportunity Funds) entail relatively greater risk of
loss of income and principal than investments in higher rated securities and
market prices of high yield securities may fluctuate more than market prices of
higher rated securities. Foreign investments by certain Funds involve risk and
opportunity considerations not typically associated with investing in U.S.
companies. The U.S. Dollar value of a foreign security tends to decrease when
the value of the U.S. Dollar rises against the foreign currency in which the
security is denominated and tends to increase when the value of the U.S. Dollar
falls against such currency. Thus, the U.S. Dollar value of foreign securities
in a Fund's portfolio, and the Fund's net asset value, may change in response to
changes in currency exchange rates even though the value of the foreign
securities in local currency terms may not have changed. A Fund's investments in
foreign securities may be in developed countries or in countries considered by
the Fund's investment manager to be developing or "emerging" markets, which
involve exposure to economic structures that are generally less diverse and
mature than in the United States, and to political systems that may be less
stable. There are special risks associated with options, financial futures,
foreign currency and other derivative transactions and there is no assurance
that use of those investment techniques will be successful. The Opportunity Fund
may borrow money for leverage purposes, which can exaggerate the effect on its
net asset value of any increase or decrease in the market value of the Fund's
portfolio. The government guarantee of the U.S. Government securities in which
certain Funds invest (principally
 
                                        1
<PAGE>   82
 
the Adjustable Rate, Government, Mortgage and Short-Intermediate Government
Funds) does not guarantee the market value of the shares of such Funds.
Normally, the value of investments in U.S. Government securities, as with most
debt securities, varies inversely with changes in interest rates. See
"Investment Objectives, Policies and Risk Factors."
 
PURCHASES AND REDEMPTIONS. Each Fund provides investors with the option of
purchasing shares in the following ways:
 
<TABLE>
<S>                                         <C>
Class A Shares............................  Offered at net asset value plus a maximum sales charge of
                                            4.5% (3.5% for the Adjustable Rate and Short-Intermediate
                                            Government Funds) of the offering price. Reduced sales
                                            charges apply to purchases of $100,000 or more. Class A
                                            shares purchased at net asset value under the Large Order
                                            NAV Purchase Privilege may be subject to a 1% contingent
                                            deferred sales charge if redeemed within one year of
                                            purchase and a .50% contingent deferred sales charge if
                                            redeemed during the second year of purchase.
Class B Shares............................  Offered at net asset value, subject to a Rule 12b-1
                                            distribution fee and a contingent deferred sales charge that
                                            declines from 4% to zero on certain redemptions made within
                                            six years of purchase. Class B shares automatically convert
                                            into Class A shares (which have lower ongoing expenses) six
                                            years after purchase.
Class C Shares............................  Offered at net asset value without an initial sales charge,
                                            but subject to a Rule 12b-1 distribution fee and a 1%
                                            contingent deferred sales charge on redemptions made within
                                            one year of purchase. Class C shares do not convert into
                                            another class.
</TABLE>
 
Each class of shares represents interests in the same portfolio of investments
of a Fund. The minimum initial investment is $1,000 and each investment
thereafter must be at least $100. Shares are redeemable at net asset value,
which may be more or less than original cost, subject to any applicable
contingent deferred sales charge. See "Purchase of Shares" and "Redemption or
Repurchase of Shares."
 
INVESTMENT MANAGER AND UNDERWRITER. Zurich Kemper Investments, Inc. ("ZKI")
serves as investment manager for each Fund. ZKI is paid an investment management
fee by each Fund based upon the average daily net assets of that Fund at an
effective annual rate that differs for each Fund. Zurich Investment Management
Limited ("ZIML"), an affiliate of ZKI, is the sub-adviser for each of the
Diversified, High Yield, Income and Capital and Opportunity Funds and is paid by
ZKI a fee of .30% of the portion of the average daily net assets of that Fund
allocated by ZKI to ZIML for management. ZIML is not expected to continue as
sub-adviser after the closing of the acquisition of Scudder, Stevens & Clark,
Inc. ("Scudder") by Zurich Insurance Company ("Zurich"). For further details see
"Investment Manager and Underwriter." Kemper Distributors, Inc. ("KDI"), a
wholly owned subsidiary of ZKI, is principal underwriter and administrator for
each Fund. For Class B shares and Class C shares, KDI receives a Rule 12b-1
distribution fee of .75 of 1% of average daily net assets. KDI also receives the
amount of any contingent deferred sales charges paid on the redemption of
shares. Administrative services are provided to shareholders under
administrative services agreements with KDI. Each Fund pays an administrative
services fee at the annual rate of up to .25 of 1% of average daily net assets
of each class of the Fund, which KDI pays to various broker-dealer firms and
other service or administrative firms. See "Investment Manager and Underwriter."
 
DIVIDENDS. Each Fund normally distributes monthly dividends of net investment
income and distributes any net realized capital gains at least annually. Income
and capital gain dividends of a Fund are automatically reinvested in additional
shares of that Fund, without a sales charge, unless the shareholder makes a
different election. See "Dividends and Taxes."
 
GENERAL. In the opinion of the staff of the Securities and Exchange Commission,
the use of this combined prospectus may make each Fund liable for any
misstatement or omission in this prospectus regardless of the particular Fund to
which it pertains.

(5) As a result of the accrual of 12b-1 fees, long-term shareholders may pay
    more than the economic equivalent of the maximum initial sales charges
    permitted by the National Association of Securities Dealers.
(6) "Other Expenses" have been estimated for the Opportunity Fund for the
    current fiscal year. These expenses include estimated interest expense of
    .60% of average net assets. Interest expense represents interest paid by the
    Opportunity Fund on borrowings for the purpose of making additional
    portfolio investments. Excluding interest expense, "Total Operating
    Expenses" would be for Class A, 1.25%, for Class B, 2.13%, and for Class C,
    2.10%.

Securities and Exchange Commission. This hypothetical rate of return is not
intended to be representative of past or future performance of any Fund. THE
EXAMPLE SHOULD NOT BE CONSIDERED TO BE A REPRESENTATION OF PAST OR FUTURE
EXPENSES. ACTUAL EXPENSES MAY BE GREATER OR LESS THAN THOSE SHOWN.

(a) ZKI agreed to waive its management fee and to absorb certain other operating
expenses of the Adjustable Rate Fund through December 31, 1992. Thereafter,
these expenses were gradually reinstated through January 31, 1994. Without this
agreement, the ratio of expenses to average net assets and the ratio of net
investment income to average net assets for Class A Shares would have been .99%
and 3.90%, respectively, for fiscal 1994, .95% and 4.70%, respectively, for
fiscal 1993, and .90% and 6.40%, respectively, for fiscal 1992.

NOTES FOR ALL FUNDS:
 
Total return does not reflect the effect of any sales charges. The Adjustable
Rate, Diversified, Government and Income and Capital Funds are separate
Massachusetts business trusts. The Mortgage and Short-Intermediate Government
Funds are separate portfolios of Kemper Portfolios, a Massachusetts business
trust, and the High Yield and Opportunity Funds are separate portfolios of
Kemper High Yield Series, a Massachusetts business trust. See "Capital
Structure."
 
The Opportunity Fund (not shown above) commenced operations on October 1, 1997.
 
INVESTMENT OBJECTIVES, POLICIES AND RISK FACTORS
 
The following information sets forth each Fund's investment objective and
policies. Each Fund's returns and net asset value will fluctuate and there is no
assurance that any Fund will achieve its objective.
 
ADJUSTABLE RATE FUND. The Adjustable Rate Fund seeks high current income
consistent with low volatility of principal. Under normal market conditions, the
Fund will, as a fundamental policy, invest at least 65% of its total assets in
adjustable rate securities issued or guaranteed by the U.S. Government, its
agencies or instrumentalities ("U.S. Government Securities"). See "Government
Fund" below concerning U.S. Government Securities and the risks related to those
securities, including the fact that the government guarantee of such securities
in the Fund's portfolio does not guarantee the net asset value of the Fund's
shares. The Fund is designed for the investor who seeks a higher yield than a
stable price money market fund or an insured bank certificate of deposit and
less fluctuation in net asset value than a longer-term bond fund; unlike money
market funds, however, the Fund does not seek to maintain a stable net asset
value and, unlike an insured bank certificate of deposit, the Fund's shares are
not insured. There is no assurance that the Fund will achieve its objective.
 
                                       14

Adjustable rate securities bear interest at rates that adjust at periodic
intervals in response to changes in market levels of interest rates generally.
As the interest rates are reset periodically, yields on such securities will
gradually align themselves to reflect changes in market interest rates. The
adjustable interest rate feature of the securities in which the Fund invests
generally will act as a buffer to reduce sharp changes in the Fund's net asset
value in response to normal interest rate fluctuations. As the interest rates on
the Fund's investments are reset periodically, yields of portfolio securities
will gradually align themselves to reflect changes in market rates and should
cause the net asset value of the Fund's shares to fluctuate less dramatically
than it would if the Fund invested in long-term, fixed rate securities.
Adjustable rate securities allow the Fund to participate in increases in
interest rates through periodic adjustments in the interest rate resulting in
both higher current yields and lower price fluctuations. During periods of
declining interest rates, of course, the coupon rates may readjust downward,
resulting in lower yields to the Fund. Further, because of this feature, the
value of adjustable rate mortgages is unlikely to rise during periods of
declining interest rates to the same extent as fixed rate instruments. As with
other mortgage-backed securities, interest rate declines may result in
accelerated prepayment of mortgages, and the proceeds from such prepayments must
be reinvested at lower prevailing interest rates. However, during periods of
rising interest rates, changes in the coupon rate lag behind changes in the
market rate, possibly resulting in a lower net asset value until the coupon
resets to market rates. Thus, investors could suffer some principal loss if they
sold their shares of the Fund before the interest rates on portfolio investments
are adjusted to reflect current market rates. During periods of extreme
fluctuations in interest rates, the Fund's net asset value will fluctuate as
well.
 
The Fund may invest without limit in Mortgage-Backed Securities, as described
under "Mortgage Fund" below. Mortgage-Backed Securities can have either a fixed
rate of interest or an adjustable rate. Adjustable rate mortgage securities in
which the Fund generally invests would have the same characteristics as
described above with respect to adjustable rate securities. In addition, since
most mortgage securities in the Fund's portfolio will generally have annual
reset caps of 100 to 200 basis points (1-2%), fluctuation in interest rates
above these levels could cause such mortgage securities to "cap out" and to
behave more like long-term, fixed rate debt securities.
 
To help protect the value of the Fund's portfolio primarily from interest rate
fluctuations, the Fund may engage in interest rate swaps and other swap-related
products such as interest rate "caps" and "floors." The Fund will enter into
these transactions normally to preserve a return or spread on a particular
investment or portion of its portfolio or to protect against any increase in the
price of securities the Fund anticipates purchasing. There is no assurance that
these transactions will be successful. The Fund will not sell interest rate caps
or floors that it does not own. See "Additional Investment Information--Interest
Rate Swaps and Swap-Related Products" below.
 
The Fund may also invest up to 35% of its total assets in securities other than
adjustable rate U.S. Government Securities including, without limitation,
privately issued Mortgage-Backed Securities, commercial paper and other debt
obligations of corporations and other business organizations, certificates of
deposit, bankers' acceptances and time deposits and other debt securities such
as convertible securities and preferred stocks. These securities will, at the
time of purchase, be rated within the two highest grades (Aaa or Aa) assigned by
Moody's Investors Service, Inc. ("Moody's"), or (AAA or AA) by Standard & Poor's
Corporation ("S&P"), or will be non-rated but of comparable quality in the
opinion of the investment manager.
 
The Fund also may invest in obligations collateralized by a portfolio or pool of
mortgages, Mortgage-Backed Securities, U.S. Government Securities or other
assets and may engage in options and financial futures transactions, securities
lending, delayed delivery transactions and other portfolio strategies. See
"Additional Investment Information" below.
 
Additional information concerning the Adjustable Rate Fund appears in the
"Interest Rate Swaps, Caps and Floors" and "Additional Information--Adjustable
Rate Securities" sections under "Investment Policies and Techniques" in the
Statement of Additional Information.
 
DIVERSIFIED FUND.  The Diversified Fund seeks high current return. The Fund
pursues its objective by investing primarily in fixed income securities and
dividend-paying common stocks and by writing options. Current return includes
interest income, common stock dividends and any net short-term gains.
 
                                       15
<PAGE>   96
 
Investment in fixed income securities will include corporate debt obligations,
U.S. and Canadian Government securities, obligations of U.S. and Canadian
banking institutions, convertible securities, preferred stocks, and cash and
cash equivalents, including repurchase agreements. Investment in equity
securities will primarily be in dividend-paying common stocks. The percentage of
assets invested in fixed income and equity securities will vary from time to
time depending upon the judgment of the investment manager as to general market
and economic conditions, trends in yields and interest rates and changes in
fiscal or monetary policies. The Fund may invest up to 50% of its total assets
in foreign securities that are traded principally in securities markets outside
the United States. Foreign securities present certain risks in addition to those
presented by domestic securities, including risks associated with currency
fluctuations, possible imposition of foreign governmental regulations or taxes
adversely affecting portfolio securities and generally different degrees of
liquidity, market volatility and availability of information. See "Special Risk
Factors--Foreign Securities" below.
 
The Fund may invest without limit in high yield, fixed income securities,
commonly referred to as "junk bonds," that are in the lower rating categories
and those that are non-rated. The high yield, fixed income securities (debt and
preferred stock issues, including convertibles and assignments or participations
in loans) in which the Fund may invest normally offer a current yield or yield
to maturity that is significantly higher than the yield available from
securities rated in the four highest categories assigned by S&P or Moody's. The
characteristics of the securities in the Fund's portfolio, such as the maturity
and the type of issuer, will affect yields and yield differentials, which vary
over time. The actual yield realized by the investor is subject, among other
things, to the Fund's expenses and the investor's transaction costs.
 
The Fund may also purchase options on securities and index options, purchase and
sell financial futures contracts and options on financial futures contracts,
engage in foreign currency transactions, engage in delayed delivery transactions
and lend its portfolio securities. See "Special Risk Factors--Foreign
Securities" and "Additional Investment Information" below. Under normal market
conditions, the Fund will invest at least 65% of its total assets in income
producing investments. In periods of unusual market conditions, the Fund may,
for defensive purposes, temporarily retain all or any part of its assets in cash
or cash equivalents.
 
There are market and investment risks with any security and the value of an
investment in the Fund will fluctuate over time. In seeking to achieve its
investment objective, the Fund will invest in fixed income securities based on
the investment manager's analysis without relying on any published ratings. The
Fund will invest in a particular fixed income security if in the investment
manager's view, the increased yield offered, regardless of published ratings, is
sufficient to compensate for a reasonable element of assumed risk. Since
investments will be based upon the investment manager's analysis rather than
upon published ratings, achievement of the Fund's goals may depend more upon the
abilities of the investment manager than would otherwise be the case.
Investments in lower rated or non-rated securities, while generally providing
greater income and opportunity for gain than investments in higher rated
securities, entail greater risk of loss of income and principal. See "Special
Risk Factors--High Yield (High Risk) Bonds" below and "Appendix--Ratings of
Investments" in the Statement of Additional Information.
 
Since interest rates vary with changes in economic, market, political and other
conditions, there can be no assurance that historic interest rates are
indicative of rates that may prevail in the future. The values of fixed income
securities in the Fund's portfolio will fluctuate depending upon market factors
and inversely with current interest rate levels. The market value of equity
securities in the Fund's portfolio will also fluctuate with market and other
conditions.
 
GOVERNMENT FUND. The Government Fund seeks high current income, liquidity and
security of principal by investing in obligations issued or guaranteed by the
U.S. Government or its agencies, and by obtaining rights to acquire such
securities. The Fund's yield and net asset value will fluctuate and there can be
no assurance that the Fund will attain its objective.
 
The Fund intends to invest some or all of its assets in Government National
Mortgage Association ("GNMA") Certificates of the modified pass-through type.
These GNMA Certificates are debt securities issued by a mortgage
 
                                       16
<PAGE>   97
 
banker or other mortgagee and represent an interest in one or a pool of
mortgages insured by the Federal Housing Administration or guaranteed by the
Veterans Administration. GNMA guarantees the timely payment of monthly
installments of principal and interest on modified pass-through Certificates at
the time such payments are due, whether or not such amounts are collected by the
issuer of these Certificates on the underlying mortgages.
 
The National Housing Act provides that the full faith and credit of the United
States is pledged to the timely payment of principal and interest by GNMA of
amounts due on these GNMA Certificates, and an assistant attorney general of the
United States has rendered an opinion that this guarantee by GNMA is a general
obligation of the United States backed by its full faith and credit.
 
Mortgages included in single family residential mortgage pools backing an issue
of GNMA Certificates have a maximum maturity of 30 years. Scheduled payments of
principal and interest are made to the registered holders of GNMA Certificates
(such as the Fund) each month. Unscheduled prepayments of mortgages included in
these pools occur as a result of the prepayment or refinancing of such mortgages
by homeowners or as a result of the foreclosure of such mortgages. Such
prepayments are passed through to the registered holders of GNMA Certificates
with the regular monthly payments of principal and interest, which has the
effect of reducing future payments on such Certificates. That portion of monthly
payments received by the Fund which represents interest and discount will be
included in the Fund's net investment income. See "Dividends and Taxes."
Principal payments on a GNMA Certificate will be reinvested by the Fund.
 
The balance of the Fund's assets, other than those invested in GNMA Certificates
and options and financial futures contracts as discussed below, will be invested
in obligations issued or guaranteed by the United States or by its agencies.
There are two broad categories of U.S. Government-related debt instruments: (a)
direct obligations of the U.S. Treasury, and (b) securities issued or guaranteed
by U.S. Government agencies. Examples of direct obligations of the U.S. Treasury
are Treasury Bills, Notes, Bonds and other debt securities issued by the U.S.
Treasury. These instruments are backed by the "full faith and credit" of the
United States. They differ primarily in interest rates, the length of maturities
and the dates of issuance. Some obligations issued or guaranteed by agencies of
the U.S. Government are backed by the full faith and credit of the United States
(such as Maritime Administration Title XI Ship Financing Bonds and Agency for
International Development Housing Guarantee Program Bonds) and others are backed
only by the rights of the issuer to borrow from the U.S. Treasury (such as
Federal Home Loan Bank Bonds and Federal National Mortgage Association Bonds).
With respect to securities supported only by the credit of the issuing agency or
by an additional line of credit with the U.S. Treasury, there is no guarantee
that the U.S. Government will provide support to such agencies and such
securities may involve risk of loss of principal and interest. U.S. Government
Securities may include "zero coupon" securities that have been stripped by the
U.S. Government of their unmatured interest coupons (see "Investment Policies
and Techniques--Zero Coupon Government Securities" in the Statement of
Additional Information for a discussion of their features and risks) and
collateralized obligations issued or guaranteed by a U.S. Government agency or
instrumentality (see "Collateralized Obligations" below).
 
U.S. Government Securities of the type in which the Fund may invest have
historically involved little risk of loss of principal if held to maturity. The
government guarantee of the U.S. Government Securities in the Fund's portfolio,
however, does not guarantee the net asset value of the shares of the Fund. There
are market risks inherent in all investments in securities and the value of an
investment in the Fund will fluctuate over time. Normally, the value of the
Fund's investments varies inversely with changes in interest rates. For example,
as interest rates rise the value of the Fund's investments will tend to decline,
and as interest rates fall the value of the Fund's investments will tend to
increase. In addition, the potential for appreciation in the event of a decline
in interest rates may be limited or negated by increased principal prepayments
in respect to certain Mortgage-Backed Securities, such as GNMA Certificates.
Prepayments of high interest rate Mortgage-Backed Securities during times of
declining interest rates will tend to lower the return of the Fund and may even
result in losses to the Fund if some securities were acquired at a premium.
Moreover, during periods of rising interest rates, prepayments of
Mortgage-Backed Securities may decline, resulting in the extension of the Fund's
average portfolio maturity. As a result, the Fund's portfolio may experience
greater volatility during periods of rising interest rates than under normal
market

conditions. With respect to U.S. Government Securities supported only by the
credit of the issuing agency or by an additional line of credit with the U.S.
Treasury, there is no guarantee that the U.S. Government will provide support to
such agencies and such securities may involve risk of loss of principal and
interest. The Fund will not invest in Mortgage-Backed Securities issued by
private issuers.
 
The Fund may also write (sell) and purchase options on securities, index
options, financial futures contracts and options on financial futures contracts
in connection with attempts to hedge its portfolio investments and not for
speculation. See "Additional Investment Information" below.
 
HIGH YIELD FUND. The primary objective of the High Yield Fund is to achieve the
highest level of current income obtainable from a professionally managed,
diversified portfolio of fixed income securities which the investment adviser
considers consistent with reasonable risk. As a secondary objective, the Fund
will seek capital gain where consistent with its primary objective.
 
The high yield, fixed income securities (debt and preferred stock issues,
including convertibles and assignments or participations in loans) in which the
Fund intends to invest are commonly referred to as "junk bonds" and normally
offer a current yield or yield to maturity that is significantly higher than the
yield available from securities rated in the four highest categories assigned by
S&P or Moody's. The characteristics of the securities in the Fund's portfolio,
such as the maturity and the type of issuer, will affect yields and yield
differentials, which vary over time. The actual yield realized by the investor
is subject, among other things, to the Fund's expenses and the investor's
transaction costs.
 
There are market and investment risks with any security and the value of an
investment in the Fund may fluctuate over time. In seeking to achieve its
investment objectives, the Fund will invest in fixed income securities based on
the investment manager's analysis without relying on published ratings. The Fund
will invest in a particular security if in the view of the investment manager
the increased yield offered, regardless of published ratings, is sufficient to
compensate for a reasonable element of assumed risk. Since investments will be
based upon the investment manager's analysis rather than upon published ratings,
achievement of the Fund's goals may depend more upon the abilities of the
investment manager than would otherwise be the case. Investment in high yield
securities, while providing greater income and opportunity for gain than
investment in higher rated securities, entails relatively greater risk of loss
of income and principal. See "Special Risk Factors--High Yield (High Risk)
Bonds" below and "Appendix--Ratings of Investments" in the Statement of
Additional Information.
 
As a secondary objective, the Fund will seek capital gain where consistent with
its primary objective. However, the Fund intends to hold portfolio securities to
maturity unless yields on alternative investments, based on current market
prices, are more attractive than those on securities held in the Fund's
portfolio or unless the investment manager determines defensive strategies
should be implemented.
 
The Fund anticipates that under normal circumstances 90 to 100% of its assets
will be invested in fixed income securities (debt and preferred stock issues,
including convertibles). The Fund may invest in common stocks, rights or other
equity securities when consistent with the Fund's objectives, but will generally
hold such equity investments only as a result of purchases of unit offerings of
fixed income securities which include such securities or in connection with an
actual or proposed conversion or exchange of fixed income securities.
 
The Fund may invest all or a portion of its assets in money market instruments
such as obligations of the U.S. Government, its agencies or instrumentalities;
other debt securities rated within the three highest grades by Moody's or S&P;
commercial paper rated within the two highest grades by either of such rating
services; bank certificates of deposit or bankers' acceptances of domestic or
Canadian chartered banks having total assets in excess of $1 billion; and any of
the foregoing investments subject to short-term repurchase agreements (an
instrument under which the purchaser acquires ownership of the underlying
obligation and the seller agrees, at the time of sale, to repurchase the
obligation at a mutually agreed upon time and price). The Fund may also purchase
and sell options on securities, index options, financial futures contracts and
options on financial futures contracts in connection with attempts to hedge its
portfolio investments and not for speculation; and it may purchase
 
                                       18
<PAGE>   99
 
foreign securities and engage in foreign currency transactions. See "Special
Risk Factors--Foreign Securities" and "Additional Investment Information" below.
 
INCOME AND CAPITAL FUND. The Income and Capital Fund seeks as high a level of
current income as is consistent with prudent investment management, preservation
of capital and ready marketability of its portfolio by investing primarily in a
diversified portfolio of investment grade debt securities. Specifically, at
least 90% of the Fund's assets will be invested in the following categories: (a)
corporate debt securities which are rated Aaa, Aa, A or Baa by Moody's or AAA,
AA, A or BBB by S&P; (b) obligations of, or guaranteed by, the United States,
its agencies or instrumentalities; (c) obligations (payable in U.S. Dollars) of,
or guaranteed by, the government of Canada or any instrumentality or political
subdivision thereof; (d) commercial paper rated Prime-1 or Prime-2 by Moody's or
A-1 or A-2 by S&P; (e) bank certificates of deposit or bankers' acceptances
issued by domestic or Canadian chartered banks having total deposits in excess
of $1 billion; (f) options on securities, index options, financial futures
contracts and options on financial futures contracts as described under
"Additional Investment Information" in connection with attempts to hedge its
portfolio investments and not for speculation; and (g) cash and cash
equivalents.
 
There are market and investment risks with any security and the value of an
investment in the Fund may fluctuate over time. Normally, the value of the
Fund's investments varies inversely with changes in interest rates. There can be
no assurance that the objective of the Fund will be achieved. Corporate debt
securities rated within the four highest grades by Moody's or S&P are generally
considered to be "investment grade." Like higher rated securities, securities
rated in the BBB or Baa categories are considered to have adequate capacity to
pay principal and interest, although they may have fewer protective provisions
than higher rated securities and thus may be adversely affected by severe
economic circumstances and are considered to have speculative characteristics.
The Fund may invest up to 10% of its total assets in fixed income securities
that are rated below BBB by S&P and Baa by Moody's or are non-rated. For a
discussion of lower rated and non-rated securities, commonly referred to as
"junk bonds," and related risks, see "Special Risk Factors--High Yield (High
Risk) Bonds" below and "Appendix--Ratings of Investments" in the Statement of
Additional Information. The Fund may also invest in foreign securities and
engage in foreign currency transactions. See "Special Risk Factors--Foreign
Securities" below.
 
MORTGAGE FUND. The Mortgage Fund seeks maximum current return from a portfolio
of U.S. Government Securities. Additionally, the Fund may engage in options and
financial futures transactions which relate to U.S. Government Securities and
may purchase or sell securities on a when-issued or delayed delivery basis. See
"Additional Investment Information" below for a discussion of such transactions
applicable to the Fund.
 
As a non-fundamental policy, at least 65% of the Fund's total assets normally
will be invested in "Mortgage-Backed Securities." Mortgage-Backed Securities are
securities that directly or indirectly represent a participation in, or are
secured by and payable from, mortgage loans secured by real property. There are
currently three basic types of Mortgage-Backed Securities: (a) those issued or
guaranteed by the U.S. Government or one of its agencies or instrumentalities,
such as the Government National Mortgage Association ("Ginnie Mae" or "GNMA"),
the Federal National Mortgage Association ("Fannie Mae" or "FNMA") and the
Federal Home Loan Mortgage Corporation ("Freddie Mac" or "FHLMC"); (b) those
issued by private issuers that represent an interest in or are collateralized by
Mortgage-Backed Securities issued or guaranteed by the U.S. Government or one of
its agencies or instrumentalities; and (c) those issued by private issuers that
represent an interest in or are collateralized by whole mortgage loans or
Mortgage-Backed Securities without a government guarantee but usually having
some form of private credit enhancement. The dominant issuers or guarantors of
Mortgage-Backed Securities today are GNMA, FNMA and FHLMC. GNMA creates mortgage
securities from pools of government guaranteed or insured (Federal Housing
Authority or Veterans Administration) mortgages originated by mortgage bankers,
commercial banks, and savings and loan associations. FNMA and FHLMC issue
Mortgage-Backed Securities from pools of conventional and federally insured
and/or guaranteed residential mortgages obtained from various entities,
including savings and loan associations, savings banks, commercial banks, credit
 
                                       19
<PAGE>   100
 
unions and mortgage bankers. Mortgage-Backed Securities issued by GNMA, FNMA and
FHLMC are considered U.S. Government Securities. The Fund will not invest in
Mortgage-Backed Securities issued by private issuers.
 
U.S. Government Securities of the type in which the Fund may invest have
historically involved little risk of loss of principal if held to maturity. The
government guarantee of the securities in the Fund, however, does not guarantee
the net asset value of the shares of the Fund. There are market risks inherent
in all investments in securities and the value of an investment in the Fund will
fluctuate over time. Normally, the value of the Fund's investments varies
inversely with changes in interest rates. For example, as interest rates rise,
the value of the Fund's investments will tend to decline and, as interest rates
fall, the value of the Fund's investments will tend to increase. In addition,
the potential for appreciation in the event of a decline in interest rates may
be limited or negated by increased principal prepayments in respect to certain
Mortgage-Backed Securities, such as GNMA Certificates. Prepayment of high
interest rate Mortgage-Backed Securities during times of declining interest
rates will tend to lower the return of the Fund and may even result in losses to
the Fund if some securities were acquired at a premium. Moreover, during periods
of rising interest rates, prepayments of Mortgage-Backed Securities may decline,
resulting in the extension of the Fund's average portfolio maturity. As a
result, the Fund's portfolio may experience greater volatility during periods of
rising interest rates than under normal market conditions.
 
OPPORTUNITY FUND. The Opportunity Fund seeks total return through high current
income and capital appreciation. The Fund will invest primarily in fixed income
securities and under normal market conditions, the Fund will, invest at least
65% of its total assets in high yield, fixed income securities. The Fund
anticipates that under normal conditions approximately 80 to 90% of its total
assets will be held in high yield, fixed income securities.
 
The high yield, fixed income securities (debt and preferred stock issues,
including convertibles and assignments or participations in loans) in which the
Fund intends to invest are commonly referred to as "junk bonds" and normally
offer a current yield or yield to maturity that is significantly higher than the
yield available from securities rated in the four highest categories assigned by
S&P or Moody's. The characteristics of the securities in the Fund's portfolio,
such as the maturity and the type of issuer, will affect yields and yield
differentials, which vary over time. The actual yield realized by the investor
is subject, among other things, to the Fund's expenses and the investor's
transaction costs.
 
There are market and investment risks with any security and the value of an
investment in the Fund may fluctuate over time. In seeking to achieve its
investment objective, the Fund will invest in fixed income securities based on
the investment manager's analysis without relying on published ratings. The Fund
will invest in a particular security if in the view of the investment manager
the increased yield offered, regardless of published ratings, is sufficient to
compensate for a reasonable element of assumed risk. Since investments will be
based upon the investment manager's analysis rather than upon published ratings,
achievement of the Fund's goals may depend more upon the abilities of the
investment manager than would otherwise be the case. Investment in high yield
securities, while providing greater income and opportunity for gain than
investment in higher rated securities, entails relatively greater risk of loss
of income and principal. See "Special Risk Factors--High Yield (High Risk)
Bonds" below and "Appendix--Ratings of Investments" in the Statement of
Additional Information.
 
The Fund may invest up to a maximum of 20% of its total assets in common stocks,
rights or other equity securities; generally of companies that issue high yield,
fixed income securities. The Fund anticipates that under normal circumstances
approximately 10% of its total assets will be in equity securities.
 
The Fund may borrow money for leverage purposes, which can exaggerate the effect
on its net asset value for any increase or decrease in the market value of the
Fund's portfolio. Money borrowed for leveraging will be limited to 20% of the
total assets of the Fund, including the amount borrowed. The Fund anticipates
that under normal conditions, the Fund would keep the leverage portion under 10%
of its total assets. These borrowings are subject to interest costs which may or
may not be recovered by the return received on the securities purchased. Under
certain circumstances, the interest costs may exceed the return received on the
securities purchased.
 
                                       20
<PAGE>   101
 
To help protect the value of the Fund's portfolio primarily from interest rate
fluctuations, the Fund may engage in interest rate swaps and other swap-related
products such as interest rate "caps" and "floors." The Fund will enter into
these transactions normally to preserve a return or spread on a particular
investment or portion of its portfolio or to protect against any increase in the
price of securities the Fund anticipates purchasing. There is no assurance that
these transactions will be successful. The Fund will not sell interest rate caps
or floors that it does not own. See "Additional Investment Information--Interest
Rate Swaps and Swap-Related Products" below.
 
When a defensive position is deemed advisable, all or a significant portion of
the Fund's assets may be held temporarily in cash or defensive type securities,
such as high-grade debt securities, securities of the U.S. Government or its
agencies and high quality money market instruments, including repurchase
agreements. The Fund may also: (i) purchase foreign securities and engage in
foreign currency transactions and (ii) purchase and sell options on securities,
index options, financial futures contracts and options on financial futures
contracts. See "Special Risk Factors--Foreign Securities" and "Additional
Investment Information" below.
 
SHORT-INTERMEDIATE GOVERNMENT FUND. The Short-Intermediate Government Fund
seeks, with equal emphasis, high current income and preservation of capital from
a portfolio composed primarily of short and intermediate-term U.S. Government
Securities. Under normal market conditions, the Fund will, as a fundamental
policy, invest at least 65% of its total assets in U.S. Government Securities
and repurchase agreements of U.S. Government Securities. See "Government Fund"
above for a discussion of U.S. Government Securities and the risks related to
those securities, including the fact that the government guarantee of U.S.
Government Securities in the Fund does not guarantee the net asset value of the
shares of the Fund.
 
Under normal market conditions, the Fund will maintain a Dollar-weighted average
portfolio maturity of more than two years but less than five years. The maturity
of a security held by the Fund will generally be considered to be the time
remaining until repayment of the principal amount of such security, except that
the maturity of a security may be considered to be a shorter period in the case
of (a) contractual rights to dispose of a security, because such rights limit
the period during which the Fund bears a market risk with respect to the
security, and (b) Mortgage-Backed Securities, because of possible prepayment of
principal on the mortgages underlying such securities. Short and
intermediate-term securities generally are more stable and less susceptible to
principal decline than longer term securities. While short and intermediate-term
securities in most cases offer lower yields than securities with longer
maturities, the Fund will seek to enhance income through limited investment in
fixed income securities other than U.S. Government Securities. The investment
manager believes that investment in short and intermediate-term securities
allows the Fund to seek both high current income and preservation of capital.
There is, however, no assurance that the Fund's objective will be achieved. The
return and net asset value of the Fund will fluctuate over time.
 
Up to 35% of the total assets of the Fund may be invested in fixed income
securities other than U.S. Government Securities. Such other fixed income
securities include: (a) corporate debt securities that are rated at the time of
purchase within the four highest grades by either Moody's (Aaa, Aa, A, or Baa)
or S&P (AAA, AA, A, or BBB); (b) commercial paper that is rated at the time of
purchase within the two highest grades by either Moody's (Prime-1 or Prime-2) or
S&P (A-1 or A-2); (c) bank certificates of deposit (including term deposits) or
bankers' acceptances issued by domestic banks (including their foreign branches)
and Canadian chartered banks having total assets in excess of $1 billion; and
(d) repurchase agreements with respect to any of the foregoing. Corporate debt
securities rated within the four highest grades by Moody's or S&P are generally
considered to be "investment grade." Like higher rated securities, securities
rated in the BBB or Baa categories are considered to have adequate capacity to
pay principal and interest, although they may have fewer protective provisions
than higher rated securities and thus may be adversely affected by severe
economic circumstances and are considered to have speculative characteristics.
 
During temporary defensive periods when the investment manager deems it
appropriate, the Fund may invest all or a portion of its assets in cash or
short-term high quality money market instruments, including short-term U.S.
 
                                       21
<PAGE>   102
 
Government Securities and repurchase agreements with respect to such securities.
The yields on these securities tend to be lower than the yields on other
securities to be purchased by the Fund.
 
The Fund may purchase or sell securities on a when-issued or delayed delivery
basis. The Fund may invest in collateralized obligations which, consistent with
the limitations reflected above, may be privately issued or may be issued or
guaranteed by U.S. Government agencies or instrumentalities. The Fund also may
engage in options or financial futures transactions in connection with attempts
to hedge its portfolio investments and not for speculation. See "Additional
Investment Information" below.
 
SPECIAL RISK FACTORS--HIGH YIELD (HIGH RISK) BONDS. As stated above, the
Diversified Fund may, and the High Yield and Opportunity Funds do, invest a
substantial portion of their assets in fixed income securities offering high
current income. Subject to its specific investment objective and policies as
described above, the Income and Capital Fund may invest up to 10% of its assets
in such securities. Such high yield (high risk), fixed income securities
ordinarily will be in the lower rating categories (securities rated below the
fourth category) of recognized rating agencies or will be non-rated. Lower-rated
and non-rated securities, which are commonly referred to as "junk bonds," have
widely varying characteristics and quality. These lower rated and non-rated
fixed income securities are considered, on balance, as predominantly speculative
with respect to capacity to pay interest and repay principal in accordance with
the terms of the obligation and generally will involve more credit risk than
securities in the higher rating categories. Accordingly, an investment in the
Diversified, High Yield or Opportunity Funds may not constitute a complete
investment program and may not be appropriate for all investors.
 
The market values of such securities tend to reflect individual corporate
developments to a greater extent than do those of higher rated securities, which
react primarily to fluctuations in the general level of interest rates. Such
lower rated securities also are more sensitive to economic conditions than are
higher rated securities. Adverse publicity and investor perceptions regarding
lower rated bonds, whether or not based on fundamental analysis, may depress the
prices for such securities. These and other factors adversely affecting the
market value of high yield securities will adversely affect each Fund's net
asset value.
 
The investment philosophy of the Diversified, High Yield and Opportunity Funds
with respect to high yield (high risk) bonds is based upon the premise that over
the long term a broadly diversified portfolio of high yield fixed income
securities should, even taking into account possible losses, provide a higher
net return than that achievable on a portfolio of higher rated securities. The
Funds seek to achieve the highest yields possible while reducing relative risk
through (a) broad diversification, (b) credit analysis by the investment manager
of the issuers in which the Funds invest, (c) purchase of high yield securities
at discounts from par or stated value when practicable and (d) monitoring and
seeking to anticipate changes and trends in the economy and financial markets
that might affect the prices of portfolio securities. The investment manager's
judgment as to the "reasonableness" of the risk involved in any particular
investment will be a function of its experience in managing fixed income
investments and its evaluation of general economic and financial conditions, a
specific issuer's business and management, cash flow, earnings coverage of
interest and dividends, ability to operate under adverse economic conditions,
and fair market value of assets, and of such other considerations as the
investment manager may deem appropriate. The investment manager, while seeking
maximum current yield, will monitor current corporate developments with respect
to portfolio securities and potential investments and to broad trends in the
economy. In some circumstances, defensive strategies may be implemented to
preserve or enhance capital even at the sacrifice of current yield. Defensive
strategies, which may be used singly or in any combination, may include, but are
not limited to, investments in discount securities or investments in money
market instruments as well as futures and options strategies.
 
High yield (high risk) securities frequently are issued by corporations in the
growth stage of their development. They may also be issued in connection with a
corporate reorganization or a corporate takeover. Companies that issue such high
yielding securities often are highly leveraged and may not have available to
them more traditional methods of financing. Therefore, the risk associated with
acquiring the securities of such issuers generally is greater than is the case
with higher rated securities. For example, during an economic downturn or
recession,
 
                                       22
<PAGE>   103
 
highly leveraged issuers of high yield securities may experience financial
stress. During such periods, such issuers may not have sufficient revenues to
meet their interest payment obligations. The issuer's ability to service its
debt obligations may also be adversely affected by specific corporate
developments, or the issuer's inability to meet specific projected business
forecasts, or the unavailability of additional financing. The risk of loss from
default by the issuer is significantly greater for the holders of high yield
securities because such securities are generally unsecured and are often
subordinated to other creditors of the issuer. Although some risk is inherent in
all securities ownership, holders of fixed income securities have a claim on the
assets of the issuer prior to the holders of common stock. Therefore, an
investment in fixed income securities generally entails less risk than an
investment in common stock of the same issuer.
 
A Fund may have difficulty disposing of certain high yield (high risk)
securities because they may have a thin trading market. Because not all dealers
maintain markets in all high yield securities, the Funds anticipate that such
securities could be sold only to a limited number of dealers or institutional
investors. The lack of a liquid secondary market may have an adverse effect on
the market price and a Fund's ability to dispose of particular issues and may
also make it more difficult for a Fund to obtain accurate market quotations for
purposes of valuing the Fund's assets. Market quotations generally are available
on many high yield issues only from a limited number of dealers and may not
necessarily represent firm bids of such dealers or prices for actual sales.
 
Zero coupon securities and pay-in-kind bonds involve additional special
considerations. Zero coupon securities are debt obligations that do not entitle
the holder to any periodic payments of interest prior to maturity or a specified
cash payment date when the securities begin paying current interest (the "cash
payment date") and therefore are issued and traded at a discount from their face
amount or par value. The market prices of zero coupon securities are generally
more volatile than the market prices of securities that pay interest
periodically and are likely to respond to changes in interest rates to a greater
degree than do securities paying interest currently having similar maturities
and credit quality. Zero coupon, pay-in-kind or deferred interest bonds carry
additional risk in that, unlike bonds that pay interest throughout the period to
maturity, a Fund will realize no cash until the cash payment date unless a
portion of such securities is sold and, if the issuer defaults, a Fund may
obtain no return at all on its investment.
 
Current federal income tax law requires the holder of a zero coupon security or
of certain pay-in-kind bonds (bonds which pay interest through the issuance of
additional bonds) to accrue income with respect to these securities prior to the
receipt of cash payments. To maintain its qualification as a regulated
investment company and avoid liability for federal income and excise taxes, a
Fund will be required to distribute income accrued with respect to these
securities and may be required to dispose of portfolio securities under
disadvantageous circumstances in order to generate cash to satisfy these
distribution requirements.
 
Additional information concerning high yield (high risk) securities appears
under "Appendix--Portfolio Composition of High Yield Bonds" below and
"Appendix--Ratings of Investments" in the Statement of Additional Information.
 
SPECIAL RISK FACTORS--FOREIGN SECURITIES. The Diversified, High Yield, Income
and Capital and Opportunity Funds have the discretion to invest a portion of
their assets in foreign securities that are traded principally in securities
markets outside the United States. These Funds currently limit investment in
foreign securities not publicly traded in the United States to 50% of total
assets in the case of the Diversified Fund and 25% of total assets in the case
of the High Yield, Income and Capital and Opportunity Funds. These Funds may
also invest without limit in U.S. Dollar denominated American Depository
Receipts ("ADRs"), which are bought and sold in the United States and are not
subject to the preceding limitation. In connection with their foreign securities
investments, these Funds may, to a limited extent, engage in foreign currency
exchange, options and futures transactions as a hedge and not for speculation.
See "Additional Investment Information--Options and Financial Futures
Transactions and Foreign Currency Transactions." The Short-Intermediate
Government Fund may, subject to its quality standards, invest in U.S.
Dollar-denominated securities of foreign issuers.
 
                                       23
<PAGE>   104
 
Foreign securities involve currency risks. The U.S. Dollar value of a foreign
security tends to decrease when the value of the U.S. Dollar rises against the
foreign currency in which the security is denominated and tends to increase when
the value of the U.S. Dollar falls against such currency. Fluctuations in
exchange rates may also affect the earning power and asset value of the foreign
entity issuing the security. Dividend and interest payments may be repatriated
based on the exchange rate at the time of disbursement or payment, and
restrictions on capital flows may be imposed. Losses and other expenses may be
incurred in converting between various currencies.
 
Foreign securities may be subject to foreign government taxes that reduce their
attractiveness. Other risks of investing in such securities include political or
economic instability in the country involved, the difficulty of predicting
international trade patterns and the possible imposition of exchange controls.
The prices of such securities may be more volatile than those of domestic
securities and the markets for such securities may be less liquid. In addition,
there may be less publicly available information about foreign issuers than
about domestic issuers. Many foreign issuers are not subject to uniform
accounting, auditing and financial reporting standards comparable to those
applicable to domestic issuers. There is generally less regulation of stock
exchanges, brokers, banks and listed companies abroad than in the United States.
With respect to certain foreign countries, there is a possibility of
expropriation or diplomatic developments that could affect investment in these
countries.
 
EMERGING MARKETS. A Fund's investments in foreign securities may be in developed
countries or in countries considered by the Fund's investment manager to be
developing or "emerging" markets, which involve exposure to economic structures
that are generally less diverse and mature than in the United States, and to
political systems that may be less stable. A developing or emerging market
country can be considered to be a country that is in the initial stages of its
industrialization cycle. Currently, emerging markets generally include every
country in the world other than the United States, Canada, Japan, Australia, New
Zealand, Hong Kong, Singapore and most Western European countries. Currently,
investing in many emerging markets may not be desirable or feasible because of
the lack of adequate custody arrangements for a Fund's assets, overly burdensome
repatriation and similar restrictions, the lack of organized and liquid
securities markets, unacceptable political risks or other reasons. As
opportunities to invest in securities in emerging markets develop, a Fund may
expand and further broaden the group of emerging markets in which it invests. In
the past, markets of developing or emerging market countries have been more
volatile than the markets of developed countries; however, such markets often
have provided higher rates of return to investors. The investment manager
believes that these characteristics can be expected to continue in the future.
 
Many of the risks described above relating to foreign securities generally will
be greater for emerging markets than for developed countries. For instance,
economies in individual developing markets may differ favorably or unfavorably
from the U.S. economy in such respects as growth of gross domestic product,
rates of inflation, currency depreciation, capital reinvestment, resource
self-sufficiency and balance of payments positions. Many emerging markets have
experienced substantial rates of inflation for many years. Inflation and rapid
fluctuations in inflation rates have had and may continue to have very negative
effects on the economies and securities markets of certain developing markets.
Economies in emerging markets generally are dependent heavily upon international
trade and, accordingly, have been and may continue to be affected adversely by
trade barriers, exchange controls, managed adjustments in relative currency
values and other protectionist measures imposed or negotiated by the countries
with which they trade. These economies also have been and may continue to be
affected adversely by economic conditions in the countries with which they
trade.
 
Also, the securities markets of developing countries are substantially smaller,
less developed, less liquid and more volatile than the securities markets of the
United States and other more developed countries. Disclosure, regulatory and
accounting standards in many respects are less stringent than in the United
States and other developed markets. There also may be a lower level of
monitoring and regulation of developing markets and the activities of investors
in such markets, and enforcement of existing regulations has been extremely
limited.
 
In addition, brokerage commissions, custodial services and other costs relating
to investment in foreign markets generally are more expensive than in the United
States; this is particularly true with respect to emerging markets. Such markets
have different settlement and clearance procedures. In certain markets there
have been times when
 
                                       24
<PAGE>   105
 
settlements have been unable to keep pace with the volume of securities
transactions, making it difficult to conduct such transactions. Such settlement
problems may cause emerging market securities to be illiquid. The inability of a
Fund to make intended securities purchases due to settlement problems could
cause the Fund to miss attractive investment opportunities. Inability to dispose
of a portfolio security caused by settlement problems could result either in
losses to a Fund due to subsequent declines in value of the portfolio security
or, if a Fund has entered into a contract to sell the security, could result in
possible liability to the purchaser. Certain emerging markets may lack clearing
facilities equivalent to those in developed countries. Accordingly, settlements
can pose additional risks in such markets and ultimately can expose a Fund to
the risk of losses resulting from a Fund's inability to recover from a
counterparty.
 
The risk also exists that an emergency situation may arise in one or more
emerging markets as a result of which trading securities may cease or may be
substantially curtailed and prices for a Fund's portfolio securities in such
markets may not be readily available. A Fund's portfolio securities in the
affected markets will be valued at fair value determined in good faith by or
under the direction of the Board of Trustees.
 
Investment in certain emerging market securities is restricted or controlled to
varying degrees. These restrictions or controls may at times limit or preclude
foreign investment in certain emerging market securities and increase the costs
and expenses of a Fund. Emerging markets may require governmental approval for
the repatriation of investment income, capital or the proceeds of sales of
securities by foreign investors. In addition, if a deterioration occurs in an
emerging market's balance of payments, the market could impose temporary
restrictions on foreign capital remittances.
 
FIXED INCOME. Since most foreign fixed income securities are not rated, a Fund
will invest in foreign fixed income securities based on the investment manager's
analysis without relying on published ratings. Since such investments will be
based upon the investment manager's analysis rather than upon published ratings,
achievement of a Fund's goals may depend more upon the abilities of the
investment manager than would otherwise be the case.
 
The value of the foreign fixed income securities held by a Fund, and thus the
net asset value of the Fund's shares, generally will fluctuate with (a) changes
in the perceived creditworthiness of the issuers of those securities, (b)
movements in interest rates, and (c) changes in the relative values of the
currencies in which a Fund's investments in fixed income securities are
denominated with respect to the U.S. Dollar. The extent of the fluctuation will
depend on various factors, such as the average maturity of a Fund's investments
in foreign fixed income securities, and the extent to which a Fund hedges its
interest rate, credit and currency exchange rate risks. Many of the foreign
fixed income obligations in which a Fund will invest will have long maturities.
A longer average maturity generally is associated with a higher level of
volatility in the market value of such securities in response to changes in
market conditions.
 
Investments in sovereign debt, including Brady Bonds, involve special risks.
Brady Bonds are debt securities issued under a plan implemented to allow debtor
nations to restructure their outstanding commercial bank indebtedness. Foreign
governmental issuers of debt or the governmental authorities that control the
repayment of the debt may be unable or unwilling to repay principal or pay
interest when due. In the event of default, there may be limited or no legal
recourse in that, generally, remedies for defaults must be pursued in the courts
of the defaulting party. Political conditions, especially a sovereign entity's
willingness to meet the terms of its fixed income securities, are of
considerable significance. Also, there can be no assurance that the holders of
commercial bank loans to the same sovereign entity may not contest payments to
the holders of sovereign debt in the event of default under commercial bank loan
agreements. In addition, there is no bankruptcy proceeding with respect to
sovereign debt on which a sovereign has defaulted, and a Fund may be unable to
collect all or any part of its investment in a particular issue.
 
Foreign investment in certain sovereign debt is restricted or controlled to
varying degrees, including requiring governmental approval for the repatriation
of income, capital or proceed of sales by foreign investors. These restrictions
or controls may at times limit or preclude foreign investment in certain
sovereign debt or increase the costs and expenses of a Fund. A significant
portion of the sovereign debt in which a Fund may invest is issued as
 
                                       25
<PAGE>   106
 
part of debt restructuring and such debt is to be considered speculative. There
is a history of defaults with respect to commercial bank loans by public and
private entities issuing Brady Bonds. All or a portion of the interest payments
and/or principal repayment with respect to Brady Bonds may be uncollateralized.
 
PRIVATIZED ENTERPRISES. Investments in foreign securities may include securities
issued by enterprises that have undergone or are currently undergoing
privatization. The governments of certain foreign countries have, to varying
degrees, embarked on privatization programs contemplating the sale of all or
part of their interests in state enterprises. A Fund's investments in the
securities of privatized enterprises include privately negotiated investments in
a government or state-owned or controlled company or enterprise that has not yet
conducted an initial equity offering, investments in the initial offering of
equity securities of a state enterprise or former state enterprise and
investments in the securities of a state enterprise following its initial equity
offering.
 
In certain jurisdictions, the ability of foreign entities, such as a Fund, to
participate in privatizations may be limited by local law, or the price or terms
on which the Fund may be able to participate may be less advantageous than for
local investors. Moreover, there can be no assurance that governments that have
embarked on privatization programs will continue to divest their ownership of
state enterprises, that proposed privatizations will be successful or that
governments will not re-nationalize enterprises that have been privatized.
 
In the case of the enterprises in which a Fund may invest, large blocks of the
stock of those enterprises may be held by a small group of stockholders, even
after the initial equity offerings by those enterprises. The sale of some
portion or all of those blocks could have an adverse effect on the price of the
stock of any such enterprise.
 
Prior to making an initial equity offering, most state enterprises or former
state enterprises go through an internal reorganization or management. Such
reorganizations are made in an attempt to better enable these enterprises to
compete in the private sector. However, certain reorganizations could result in
a management team that does not function as well as the enterprises's prior
management and may have a negative effect on such enterprise. In addition, the
privatization of an enterprise by its government may occur over a number of
years, with the government continuing to hold a controlling position in the
enterprise even after the initial equity offering for the enterprise.
 
Prior to privatization, most of the state enterprises in which a Fund may invest
enjoy the protection of and receive preferential treatment from the respective
sovereigns that own or control them. After making an initial equity offering
these enterprises may no longer have such protection or receive such
preferential treatment and may become subject to market competition from which
they were previously protected. Some of these enterprises may not be able to
effectively operate in a competitive market and may suffer losses or experience
bankruptcy due to such competition.
 
DEPOSITORY RECEIPTS. For many foreign securities, there are U.S. Dollar
denominated ADRs, which are bought and sold in the United States and are issued
by domestic banks. ADRs represent the right to receive securities of foreign
issuers deposited in the domestic bank or a correspondent bank. ADRs do not
eliminate all the risk inherent in investing in the securities of foreign
issuers, such as changes in foreign currency exchange rates. However, by
investing in ADRs rather than directly in foreign issuers' stock, the Fund
avoids currency risks during the settlement period. In general, there is a
large, liquid market in the United States for most ADRs. The Funds may also
invest in securities of foreign issuers in the form of European Depository
Receipts ("EDRs") and Global Depository Receipts ("GDRs") which are receipts
evidencing an arrangement with a European bank similar to that for ADRs and are
designed for use in the European and other foreign securities markets. EDRs and
GDRs are not necessarily denominated in the currency of the underlying security.
 
ADDITIONAL INVESTMENT INFORMATION. A Fund will not normally engage in the
trading of securities for the purpose of realizing short-term profits, but will
adjust its portfolio as considered advisable in view of prevailing or
anticipated market conditions and its investment objective. Accordingly, a Fund
may sell fixed income securities in anticipation of a rise in interest rates and
purchase such securities for inclusion in its portfolio in anticipation of a
decline in interest rates. Frequency of portfolio turnover will not be a
limiting factor should the investment
 
                                       26
<PAGE>   107
 
manager deem it desirable to purchase or sell securities. The portfolio turnover
rates for the Funds (except the Opportunity Fund) are listed under "Financial
Highlights." It is anticipated that, under normal circumstances, the portfolio
turnover rate for the Opportunity Fund will not exceed 300%. High portfolio
turnover (over 100%) involves correspondingly greater brokerage commissions or
other transaction costs. Higher portfolio turnover may result in the realization
of greater net short-term capital gains. See "Dividends and Taxes" in the
Statement of Additional Information.
 
A Fund (other than the Adjustable Rate and Short-Intermediate Government Funds)
may take full advantage of the entire range of maturities of fixed income
securities and may adjust the average maturity of its portfolio from time to
time, depending upon its assessment of relative yields on securities of
different maturities and its expectations of future changes in interest rates.
Thus, the average maturity of a Fund's portfolio may be relatively short (under
5 years, for example) at some times and relatively long (over 10 years, for
example) at other times. Generally, since shorter term debt securities tend to
be more stable than longer term debt securities, the portfolio's average
maturity will be shorter when interest rates are expected to rise and longer
when interest rates are expected to fall. The effective Dollar-weighted average
portfolio maturity of the Adjustable Rate Fund generally will range from less
than one year to five years. The effective Dollar-weighted average portfolio
maturity of the Short-Intermediate Government Fund generally will be more than
two years but less than five years.
 
The Adjustable Rate, Mortgage and Short-Intermediate Government Funds each may
not borrow money except as a temporary measure for extraordinary or emergency
purposes and then only in an amount up to one-third of the value of its total
assets in order to meet redemption requests without immediately selling any
portfolio securities. If, for any reason, the current value of a Fund's total
assets falls below an amount equal to three times the amount of its indebtedness
from money borrowed, the Fund will, within three days (not including Sundays and
holidays), reduce its indebtedness to the extent necessary. A Fund will not
borrow for leverage purposes. The Adjustable Rate Fund may pledge up to 15% of
its total assets to secure any such borrowings.
 
The Diversified, Government, High Yield and Income and Capital Funds may each
borrow money only for temporary or emergency purposes and not for leverage
purposes, and then only in an amount up to 5% of its assets, in order to meet
redemption requests without immediately selling any portfolio securities or
other assets. These Funds, except for the Government Fund, may not pledge their
assets in an amount exceeding the amount of the borrowings secured by such
pledge. The Government Fund may pledge up to 7 1/2% of its assets to secure any
such borrowings.
 
The maximum amount that the Opportunity Fund may borrow is one-third of the
value of its assets (including the amount borrowed). As a temporary measure for
extraordinary or emergency purposes, the Opportunity Fund may borrow money up to
one-third of the value of its total assets (including the amount borrowed) in
order to meet redemption requests without immediately selling any portfolio
securities. The Opportunity Fund may also borrow money up to 20% of the value of
its total assets (including the amount borrowed) for leverage purposes. See
"Investment Objectives, Policies and Risk Factors--Opportunity Fund" above.
 
A Fund will not purchase illiquid securities, including repurchase agreements
maturing in more than seven days, if, as a result thereof, more than 15% of the
Fund's net assets, valued at the time of the transaction, would be invested in
such securities, except that the Mortgage Fund may not purchase illiquid
securities if more than 10% of its total assets would be invested in such
securities. See "Investment Policies and Techniques--Over-the-Counter Options"
in the Statement of Additional Information for a description of the extent to
which over-the-counter traded options are in effect considered as illiquid for
purposes of a Fund's limit on illiquid securities. Each Fund may invest in
securities eligible for resale pursuant to Rule 144A under the Securities Act of
1933. This rule permits otherwise restricted securities to be sold to certain
institutional buyers, such as the Funds. Such securities may be illiquid and
subject to a Fund's limitation on illiquid securities. A "Rule 144A" security
may be treated as liquid, however, if so determined pursuant to procedures
adopted by the Board of Trustees. Investing in Rule 144A securities could have
the effect of increasing the level of illiquidity in a Fund to the extent that
qualified institutional buyers become uninterested for a time in purchasing Rule
144A securities.
 
                                       27

Each Fund has adopted certain fundamental investment restrictions which are
presented in the Statement of Additional Information and that, together with the
investment objective and policies of a Fund (for the Adjustable Rate and
Opportunity Funds, however, only those policies specifically designated in this
prospectus as fundamental), cannot be changed without approval by holders of a
majority of its outstanding voting shares. As defined in the Investment Company
Act of 1940 ("1940 Act"), this means the lesser of the vote of (a) 67% of the
shares of a Fund present at a meeting where more than 50% of the outstanding
shares are present in person or by proxy; or (b) more than 50% of the
outstanding shares of a Fund. Policies of the Adjustable Rate and Opportunity
Funds that are neither designated as fundamental nor incorporated into any of
the fundamental investment restrictions referred to above may be changed by the
Board of Trustees of the Fund without shareholder approval.
 
INTEREST RATE SWAPS AND SWAP-RELATED PRODUCTS. As stated above, the Adjustable
Rate and Opportunity Funds may engage in interest rate swaps and other
swap-related products. Swap agreements can take many different forms and are
known by a variety of names. The Adjustable Rate and Opportunity Funds are not
limited to any particular form of swap agreement if the investment manager
determines it is consistent with a fund's investment objective and policies.
 
Interest rate swaps are the exchange by the Fund with another party of their
respective commitments to pay or receive interest with respect to a notional
(agreed upon) principal amount, for example, an exchange of floating rate
payments for fixed rate payments. Interest rate swaps are generally entered into
to permit the party seeking a floating or fixed rate obligation, as the case may
be, the opportunity to acquire such obligation at a lower rate than is directly
available in the credit market. The success of such a transaction depends in
large part on the availability of fixed rate obligations at a low enough coupon
rate to cover the cost involved.
 
The purchase of an interest rate cap entitles the purchaser, to the extent that
a specified index exceeds a predetermined interest rate, to receive payments of
interest on a notional principal amount from the party selling the interest rate
cap. The purchase of an interest rate floor entitles the purchaser, to the
extent that a specified index falls below a predetermined interest rate, to
receive payments of interest on a notional principal amount from the party
selling such interest rate floor.
 
Additional information concerning interest rate swaps and swap-related products
is contained in the Statement of Additional Information under "Investment
Policies and Techniques--Interest Rate Swaps and Swap-Related Products."
 
OPTIONS AND FINANCIAL FUTURES TRANSACTIONS. A Fund may deal in options on
securities and securities indexes, which options may be listed for trading on a
national securities exchange or traded over-the-counter. In connection with
their foreign securities investments, the Diversified, High Yield, Income and
Capital and Opportunity Funds may also purchase and sell foreign currency
options.
 
The Diversified and Mortgage Funds may write (sell) covered call options on up
to 100% of net assets and may write (sell) secured put options on up to 50% of
net assets. The Adjustable Rate, Government, High Yield, Income and Capital and
Opportunity Funds each may write (sell) covered call and secured put options on
up to 25% of its net assets. Each such Fund may purchase put and call options
provided that no more than 5% of its net assets may be invested in premiums on
such options.
 
A call option gives the purchaser the right to buy, and the writer the
obligation to sell, the underlying security or other asset at the exercise price
during or at the end of the option period. A put option gives the purchaser the
right to sell, and the writer the obligation to buy, the underlying security or
other asset at the exercise price during or at the end of the option period. The
writer of a covered call owns securities or other assets that are acceptable for
escrow and the writer of a secured put invests an amount not less than the
exercise price in eligible securities or other assets to the extent that it is
obligated as a writer. If a call written by a Fund is exercised, the Fund
foregoes any possible profit from an increase in the market price of the
underlying security or other asset over the exercise price plus the premium
received. In writing puts, there is a risk that a Fund may be required to take
delivery of the underlying security or other asset at a disadvantageous price.
 
                                       28
<PAGE>   109
 
Over-the-counter traded options ("OTC options") differ from exchange traded
options in several respects. They are transacted directly with dealers and not
with a clearing corporation, and there is a risk of non-performance by the
dealer as a result of the insolvency of such dealer or otherwise, in which event
a Fund may experience material losses. However, in writing options the premium
is paid in advance by the dealer. OTC options are available for a greater
variety of securities and other assets, and a wider range of expiration dates
and exercise prices, than for exchange traded options.
 
A Fund may engage in financial futures transactions. Financial futures contracts
are commodity contracts that obligate the long or short holder to take or make
delivery of a specified quantity of a financial instrument, such as a security,
or the cash value of a securities index during a specified future period at a
specified price. A Fund will "cover" futures contracts sold by the Fund and
maintain in a segregated account certain liquid assets in connection with
futures contracts purchased by the Fund as described under "Investment Policies
and Techniques" in the Statement of Additional Information. In connection with
their foreign securities investments, the Diversified, High Yield, Income and
Capital and Opportunity Funds may also engage in foreign currency financial
futures transactions. A Fund will not enter into any futures contracts or
options on futures contracts if the aggregate of the contract value of the
outstanding futures contracts of the Fund and futures contracts subject to
outstanding options written by the Fund and, for each of the Adjustable Rate and
Opportunity Funds, the aggregate notional (agreed upon) principal amount of
interest rate swaps, would exceed 50% of the total assets of the Fund.
 
The Funds may engage in financial futures transactions and may use index options
as an attempt to hedge against market risks. For example, if a Fund owned
long-term bonds and interest rates were expected to rise, it could sell
financial futures contracts. If interest rates did increase, the value of the
bonds in the Fund would decline, but this decline would be offset in whole or in
part by an increase in the value of the Fund's futures contracts. If, on the
other hand, long-term interest rates were expected to decline, the Fund could
hold short-term debt securities and benefit from the income earned by holding
such securities, while at the same time the Fund could purchase futures
contracts on long-term bonds or the cash value of a securities index. Thus, the
Fund could take advantage of the anticipated rise in the value of long-term
bonds without actually buying them. The futures contracts and short-term debt
securities could then be liquidated and the cash proceeds used to buy long-term
bonds.
 
Futures contracts entail risks. If the investment manager's judgment about the
general direction of interest rates, markets or exchange rates is wrong, the
overall performance may be poorer than if no such contracts had been entered
into. There may be an imperfect correlation between movements in prices of
futures contracts and portfolio assets being hedged. In addition, the market
prices of futures contracts may be affected by certain factors. For example, if
participants in the futures market elect to close out their contracts rather
than meet margin requirements, distortions in the normal relationship between
the underlying assets and futures market could result. Price distortions also
could result if investors in futures contracts decide to make or take delivery
of underlying securities or other assets rather than engage in closing
transactions because of the resultant reduction in the liquidity of the futures
market. In addition, because, from the point of view of speculators, margin
requirements in the futures market are less onerous than margin requirements in
the cash market, increased participation by speculators in the futures market
could cause temporary price distortions. Due to the possibility of price
distortions in the futures market and because of the imperfect correlation
between movements in the prices of securities or other assets and movements in
the prices of futures contracts, a correct forecast of market trends by the
investment manager still may not result in a successful hedging transaction. If
any of these events should occur, a Fund could lose money on the financial
futures contracts and also on the value of its portfolio assets. The costs
incurred in connection with futures transactions could reduce a Fund's return.
 
Index options involve risks similar to those risks relating to transactions in
financial futures contracts described above. Also, an option purchased by a Fund
may expire worthless, in which case a Fund would lose the premium paid therefor.
 
                                       29
<PAGE>   110
 
A Fund may engage in futures transactions only on commodities exchanges or
boards of trade. A Fund will not engage in transactions in index options,
financial futures contracts or related options for speculation, but only as an
attempt to hedge against changes in interest rates or market conditions
affecting the values of securities which the Fund owns or intends to purchase.
 
FOREIGN CURRENCY TRANSACTIONS. The Diversified, High Yield, Income and Capital
and Opportunity Funds may each invest a limited portion of its assets in
securities denominated in foreign currencies. These Funds may engage in foreign
currency transactions in connection with their investments in foreign securities
but will not speculate in foreign currency exchange.
 
The value of the foreign securities investments of a Fund measured in U.S.
Dollars may be affected favorably or unfavorably by changes in foreign currency
exchange rates and exchange control regulations, and the Fund may incur costs in
connection with conversions between various currencies. A Fund will conduct its
foreign currency exchange transactions either on a spot (i.e., cash) basis at
the spot rate prevailing in the foreign currency exchange market, or through
forward contracts to purchase or sell foreign currencies. A forward foreign
currency exchange contract involves an obligation to purchase or sell a specific
currency at a future date, which may be any fixed number of days from the date
of the contract agreed upon by the parties, at a price set at the time of the
contract. These contracts are traded directly between currency traders (usually
large commercial banks) and their customers.
 
When a Fund enters into a contract for the purchase or sale of a security
denominated in a foreign currency, it may want to establish the U.S. Dollar cost
or proceeds, as the case may be. By entering into a forward contract in U.S.
Dollars for the purchase or sale of the amount of foreign currency involved in
an underlying security transaction, the Fund is able to protect itself against a
possible loss between trade and settlement dates resulting from an adverse
change in the relationship between the U.S. Dollar and such foreign currency.
However, this tends to limit potential gains that might result from a positive
change in such currency relationships. A Fund may also hedge its foreign
currency exchange rate risk by engaging in foreign currency financial futures
and options transactions.
 
When the investment manager believes that the currency of a particular foreign
country may suffer a substantial decline against the U.S. Dollar, it may enter
into a forward contract to sell an amount of foreign currency approximating the
value of some or all of the Fund's securities denominated in such foreign
currency. The forecasting of short-term currency market movement is extremely
difficult and whether such a short-term hedging strategy will be successful is
highly uncertain.
 
It is impossible to forecast with absolute precision the market value of
portfolio securities at the expiration of a contract. Accordingly, it may be
necessary for a Fund to purchase additional currency on the spot market (and
bear the expense of such purchase) if the market value of the security is less
than the amount of foreign currency the Fund is obligated to deliver when a
decision is made to sell the security and make delivery of the foreign currency
in settlement of a forward contract. Conversely, it may be necessary to sell on
the spot market some of the foreign currency received upon the sale of the
portfolio security if its market value exceeds the amount of foreign currency
the Fund is obligated to deliver.
 
A Fund will not enter into forward contracts or maintain a net exposure in such
contracts where the Fund would be obligated to deliver an amount of foreign
currency in excess of the value of the Fund's securities or other assets
denominated in that currency. The Diversified, High Yield, Income and Capital
and Opportunity Funds do not intend to enter into forward contracts for the
purchase of a foreign currency if they would have more than 15% of the value of
their total assets committed to such contracts. The Funds segregate cash or
liquid securities to the extent required by applicable regulation in connection
with forward foreign currency exchange contracts entered into for the purchase
of a foreign currency. A Fund generally does not enter into a forward contract
with a term longer than one year.
 
                                       30
<PAGE>   111
 
DERIVATIVES. In addition to options and financial futures transactions,
consistent with its objective, each Fund may invest in a broad array of
financial instruments and securities in which the value of the instrument or
security is "derived" from the performance of an underlying asset or a
"benchmark" such as a security index, an interest rate or a foreign currency
("derivatives"). Derivatives are most often used to manage investment risk, to
increase or decrease exposure to an asset class or benchmark (as a hedge or to
enhance return), or to create an investment position indirectly (often because
it is more efficient or less costly than direct investment). The types of
derivatives used by each Fund and the techniques employed by the investment
manager may change over time as new derivatives and strategies are developed or
regulatory changes occur.
 
SPECIAL RISK FACTORS--OPTIONS, FUTURES, FOREIGN CURRENCIES AND OTHER
DERIVATIVES. The Statement of Additional Information contains further
information about the characteristics, risks and possible benefits of options,
futures, foreign currency and other derivative transactions. See "Investment
Policies and Techniques" in the Statement of Additional Information. The
principal risks are: (a) possible imperfect correlation between movements in the
prices of options, currencies, futures or other derivatives contracts and
movements in the prices of the securities or currencies hedged, used for cover
or that the derivatives intended to replicate; (b) lack of assurance that a
liquid secondary market will exist for any particular option, futures, foreign
currency or other derivatives contract at any particular time; (c) the need for
additional skills and techniques beyond those required for normal portfolio
management; (d) losses on futures contracts resulting from market movements not
anticipated by the investment manager; and (e) the possible non-performance of
the counter-party to the derivative contract.
 
DELAYED DELIVERY TRANSACTIONS. Any of the Funds may purchase or sell portfolio
securities on a when-issued or delayed delivery basis. When-issued or delayed
delivery transactions involve a commitment by a Fund to purchase or sell
securities with payment and delivery to take place in the future (not to exceed
120 days from trade date for the Government Fund) in order to secure what is
considered to be an advantageous price or yield to the Fund at the time of
entering into the transaction. The value of fixed yield securities to be
delivered in the future will fluctuate as interest rates vary. Because a Fund is
required to set aside cash or other liquid securities to satisfy its commitments
to purchase when-issued or delayed delivery securities, flexibility to manage
the Fund's investments may be limited if commitments to purchase when-issued or
delayed delivery securities were to exceed 25% of the value of its assets.
 
To the extent a Fund engages in when-issued or delayed delivery transactions, it
will do so for the purpose of acquiring portfolio securities consistent with the
Fund's investment objective and policies. A Fund reserves the right to sell
these securities before the settlement date if deemed advisable.
 
In when-issued or delayed delivery transactions, delivery of the securities
occurs beyond normal settlement periods, but the Fund would not pay for such
securities or start earning interest on them until they are delivered. However,
when the Fund purchases securities on a when-issued or delayed delivery basis,
it immediately assumes the risks of ownership, including the risk of price
fluctuation. Failure to deliver a security purchased on a when-issued or delayed
delivery basis may result in a loss or missed opportunity to make an alternative
investment. Depending on market conditions, the Fund's when-issued and delayed
delivery purchase commitments could cause its net asset value per share to be
more volatile, because such securities may increase the amount by which its
total assets, including the value of when-issued and delayed delivery securities
it holds, exceed its net assets.
 
REPURCHASE AGREEMENTS. Each Fund may invest in repurchase agreements, under
which it acquires ownership of a security and the broker-dealer or bank agrees
to repurchase the security at a mutually agreed upon time and price, thereby
determining the yield during the Fund's holding period. In the event of a
bankruptcy or other default of a seller of a repurchase agreement, the Fund
might have expenses in enforcing its rights, and could experience losses,
including a decline in the value of the underlying securities and loss of
income. The securities underlying a repurchase agreement will be
marked-to-market every business day so that the value of such securities is at
least equal to the investment value of the repurchase agreement, including any
accrued interest thereon. In addition, the Fund must take physical possession of
the security or receive written confirmation of the purchase and a custodial or
safekeeping receipt from a third party or be recorded as the owner of the
security through the Federal
 
                                       31
<PAGE>   112
 
Reserve Book-Entry System. Repurchase agreements will be limited to transactions
with financial institutions believed by the investment manager to present
minimal credit risk. The investment manager will monitor on an on-going basis
the creditworthiness of the broker-dealers and banks with which the Funds may
engage in repurchase agreements. Repurchase agreements maturing in more than
seven days will be considered as illiquid for purposes of the Funds' limitations
on illiquid securities.
 
LENDING OF PORTFOLIO SECURITIES. Consistent with applicable regulatory
requirements, the Funds (other than the Government Fund) may lend securities
(principally to broker-dealers) without limit where such loans are callable at
any time and are continuously secured by segregated collateral (cash or other
liquid securities) equal to no less than the market value, determined daily, of
the securities loaned. The Funds will receive amounts equal to dividends or
interest on the securities loaned. The Funds will also earn income for having
made the loan. Any cash collateral pursuant to these loans will be invested in
short-term money market instruments. As with other extensions of credit, there
are risks of delay in recovery or even loss of rights in the collateral should
the borrower of the securities fail financially. However, the loans would be
made only to firms deemed by the investment manager to be of good standing, and
when the investment manager believes the potential earnings to justify the
attendant risk. Management will limit such lending to not more than one-third of
the value of a Fund's total assets.
 
COLLATERALIZED OBLIGATIONS. Subject to its investment objective and policies, a
Fund may purchase collateralized obligations, including interest only ("IO") and
principal only ("PO") securities. A collateralized obligation is a debt security
issued by a corporation, trust or custodian, or by a U.S. Government agency or
instrumentality, that is collateralized by a portfolio or pool of mortgages,
Mortgage-Backed Securities, U.S. Government Securities or other assets. The
issuer's obligation to make interest and principal payments is secured by the
underlying pool or portfolio of securities. Collateralized obligations issued or
guaranteed by a U.S. Government agency or instrumentality, such as the Federal
Home Loan Mortgage Corporation, are considered U.S. Government Securities for
purposes of this prospectus. Privately-issued collateralized obligations
collateralized by a portfolio of U.S. Government Securities are not direct
obligations of the U.S. Government or any of its agencies or instrumentalities
and are not considered U.S. Government Securities for purposes of this
prospectus. A variety of types of collateralized obligations are available
currently and others may become available in the future.
 
Since the collateralized obligations may be issued in classes with varying
maturities and interest rates, the investor may obtain greater predictability of
maturity than with direct investments in mortgage-backed securities. Classes
with shorter maturities may have lower volatility and lower yield while those
with longer maturities may have higher volatility and higher yield. This
provides the investor with greater control over the characteristics of the
investment in a changing interest rate environment. With respect to interest
only and principal only securities, an investor has the option to select from a
pool of underlying collateral the portion of the cash flows that most closely
corresponds to the investor's forecast of interest rate movements. These
instruments tend to be highly sensitive to prepayment rates on the underlying
collateral and thus place a premium on accurate prepayment projections by the
investor.
 
A Fund may invest in collateralized obligations whose yield floats inversely
against a specified index rate. These "inverse floaters" are more volatile than
conventional fixed or floating rate collateralized obligations and the yield
thereon, as well as the value thereof, will fluctuate in inverse proportion to
changes in the index upon which interest rate adjustments are based. As a
result, the yield on an inverse floater will generally increase when market
yields (as reflected by the index) decrease and decrease when market yields
increase. The extent of the volatility of inverse floaters depends on the extent
of anticipated changes in market rates of interest. Generally, inverse floaters
provide for interest rate adjustments based upon a multiple of the specified
interest index, which further increases their volatility. The degree of
additional volatility will be directly proportional to the size of the multiple
used in determining interest rate adjustments.
 
Additional information concerning collateralized obligations is contained in the
Statement of Additional Information under "Investment Policies and
Techniques--Collateralized Obligations."

INVESTMENT MANAGER. Zurich Kemper Investments, Inc. ("ZKI"), 222 South Riverside
Plaza, Chicago, Illinois 60606, is the investment manager of each Fund and
provides each Fund with continuous professional investment supervision. ZKI is
one of the largest investment managers in the country and has been engaged in
the management of investment funds for more than forty-nine years. ZKI and its
affiliates provide investment advice and manage investment portfolios for the
Kemper Funds, affiliated insurance companies and other corporate, pension,
profit-sharing and individual accounts representing approximately $89 billion
under management (including approximately $16 billion in U.S. Government

and financial services in property/casualty and life insurance, reinsurance and
structured financial solutions as well as asset management.
 
Zurich Insurance Company ("Zurich") has entered into a definitive agreement with
Scudder, Stevens & Clark, Inc. ("Scudder") pursuant to which Zurich will acquire
approximately 70% of Scudder. Upon completion of the transaction, Scudder will
change its name to Scudder Kemper Investments, Inc. ("SKI"), and ZKI will be
combined with SKI. Because the transaction would constitute an assignment of the
Funds' investment management agreements with ZKI under the Investment Company
Act of 1940, ZKI sought approval of new agreements. The Funds' boards and
shareholders have approved new agreements with SKI. If any remaining
contingencies are timely met, the transaction is expected to close December 31,
1997. Zurich will own 69.5% of SKI and senior employees of SKI will hold the
remaining 30.5%. SKI will be headquartered in New York City and the chief
executive officer of SKI will be Edmond D. Villani, Scudder's president and
chief executive officer.
 
Responsibility for overall management of each Fund rests with its Board of
Trustees and officers. Professional investment supervision is provided by ZKI.
The investment management agreements provide that ZKI shall act as each Fund's
investment adviser, manage its investments and provide it with various services
and facilities. Zurich Investment Management Limited ("ZIML"), 1 Fleet Place,
London, U.K. EC4M 7RQ, an affiliate of ZKI, is the sub-adviser for the
Diversified, High Yield, Income and Capital and Opportunity Funds. ZIML is an
indirect subsidiary of Zurich Insurance Company and has served as sub-adviser
for mutual funds since December, 1996 and investment adviser for certain
institutional accounts since August, 1988. Under the terms of the Sub-Advisory
Agreement between ZIML and ZKI, ZIML renders investment advisory and management
services with regard to such portion of the Fund's portfolio as may be allocated
to ZIML by ZKI from time to time for management of foreign securities, including
foreign currency transactions and related investments. ZKI pays ZIML for its
services a sub-advisory fee, payable monthly at the annual rate of .30% of the
portion of the average daily net assets of the Fund allocated by ZKI to ZIML for
management. ZIML is not expected to continue as sub-adviser after the closing of
the acquisition of Scudder by Zurich.

PRINCIPAL UNDERWRITER. Pursuant to an underwriting and distribution services
agreement ("distribution agreement") with each Fund, Kemper Distributors, Inc.
("KDI"), 222 South Riverside Plaza, Chicago, Illinois 60606, a wholly owned
subsidiary of ZKI, is the principal underwriter and distributor of each Fund's
shares and acts as agent of each Fund in the sale of its shares. KDI bears all
its expenses of providing services pursuant to the distribution agreement,
including the payment of any commissions. KDI provides for the preparation of
advertising or sales literature and bears the cost of printing and mailing
prospectuses to persons other than shareholders. KDI bears the cost of
qualifying and maintaining the qualification of Fund shares for sale under the
securities laws of the various states and each Fund bears the expense of
registering its shares with the Securities and Exchange Commission. KDI may
enter into related selling group agreements with various broker-dealers,
 
                                       34
<PAGE>   115
 
including affiliates of KDI, that provide distribution services to investors.
KDI also may provide some of the distribution services.
 
CLASS A SHARES. KDI receives no compensation from the Funds as principal
underwriter for Class A shares and pays all expenses of distribution of each
Fund's Class A shares under the distribution agreements not otherwise paid by
dealers or other financial services firms. As indicated under "Purchase of
Shares," KDI retains the sales charge upon the purchase of shares and pays or
allows concessions or discounts to firms for the sale of each Fund's shares.
 
CLASS B SHARES. For its services under the distribution agreement, KDI receives
a fee from each Fund, payable monthly, at the annual rate of .75% of average
daily net assets of each Fund attributable to Class B shares. This fee is
accrued daily as an expense of Class B shares. KDI also receives any contingent
deferred sales charges. See "Redemption or Repurchase of Shares--Contingent
Deferred Sales Charge--Class B Shares." KDI currently compensates firms for
sales of Class B shares at a commission rate of 3.75%.
 
CLASS C SHARES. For its services under the distribution agreement, KDI receives
a fee from each Fund, payable monthly, at the annual rate of .75% of average
daily net assets of each Fund attributable to Class C shares. This fee is
accrued daily as an expense of Class C shares. KDI currently advances to firms
the first year distribution fee at a rate of .75% of the purchase price of Class
C shares. For periods after the first year, KDI currently pays firms for sales
of Class C shares a distribution fee, payable quarterly, at an annual rate of
 .75% of net assets attributable to Class C shares maintained and serviced by the
firm and the fee continues until terminated by KDI or a Fund. KDI also receives
any contingent deferred sales charges. See "Redemption or Repurchase of
Shares--Contingent Deferred Sales Charge--Class C Shares."
 
RULE 12B-1 PLAN. Since each distribution agreement provides for fees payable as
an expense of the Class B shares and the Class C shares that are used by KDI to
pay for distribution services for those classes, that agreement is approved and
reviewed separately for the Class B shares and the Class C shares in accordance
with Rule 12b-1 under the 1940 Act, which regulates the manner in which an
investment company may, directly or indirectly, bear the expenses of
distributing its shares. As of December 1997, each Fund's Rule 12b-1 Plan has
been separated from its distribution agreement. The table below shows amounts
paid in connection with each Fund's Rule 12b-1 Plan during its 1997 fiscal year
(except the Opportunity Fund, which commenced operations on October 1, 1997).

If a Rule 12b-1 Plan (the "Plan") is terminated in accordance with its terms,
the obligation of a Fund to make payments to KDI pursuant to the Plan will cease
and the Fund will not be required to make any payments past the termination
date. Thus, there is no legal obligation for the Fund to pay any expenses
incurred by KDI in excess of its fees under a Plan, if for any reason the Plan
is terminated in accordance with its terms. Future fees under the Plan may or
may not be sufficient to reimburse KDI for its expenses incurred.
 
ADMINISTRATIVE SERVICES. KDI also provides information and administrative
services for shareholders of each Fund pursuant to administrative services
agreements ("administrative agreements"). KDI may enter into related
arrangements with various broker-dealer firms and other service or
administrative firms ("firms"), that provide
 
                                       35
<PAGE>   116
 
services and facilities for their customers or clients who are investors of the
Funds. Such administrative services and assistance may include, but are not
limited to, establishing and maintaining accounts and records, processing
purchase and redemption transactions, answering routine inquiries regarding each
Fund and its special features and such other administrative services as may be
agreed upon from time to time and permitted by applicable statute, rule or
regulation. KDI bears all its expenses of providing services pursuant to the
administrative agreement, including the payment of any service fees. For
services under the administrative agreements, each Fund pays KDI a fee, payable
monthly, at an annual rate of up to .25% of average daily net assets of Class A,
B and C shares of such Fund. With respect to Class A shares, KDI then pays each
firm a service fee at an annual rate of (a) up to .15% of net assets (.25% for
the Mortgage and Short-Intermediate Government Funds) of those accounts that it
maintains and services for each Fund attributable to shares acquired prior to
October 1, 1993, and (b) up to .25% of net assets of those accounts that it
maintains and services for each Fund attributable to Class A shares acquired on
or after October 1, 1993. With respect to Class B shares and Class C shares, KDI
pays each firm a service fee, normally payable quarterly, at an annual rate of
up to .25% of net assets of those accounts in the Fund that it maintains and
services attributable to Class B shares and Class C shares, respectively. Firms
to which service fees may be paid include affiliates of KDI.
 
CLASS A SHARES. For Class A shares, a firm becomes eligible for the service fee
based on assets in the accounts in the month following the month of purchase and
the fee continues until terminated by KDI or a Fund. The fees are calculated
monthly and normally paid quarterly.
 
CLASS B AND CLASS C SHARES. KDI currently advances to firms the first year
service fee at a rate of up to .25% of the purchase price of such shares. For
periods after the first year, KDI currently intends to pay firms a service fee
at a rate of up to .25% (calculated monthly and normally paid quarterly) of the
net assets attributable to Class B and Class C shares maintained and serviced by
the firm and the fee continues until terminated by KDI or the Fund.
 
KDI also may provide some of the above services and may retain any portion of
the fee under the administrative agreements not paid to firms to compensate
itself for administrative functions performed for each Fund. Currently, the
administrative services fee payable to KDI is based only upon Fund assets in
accounts for which a firm provides administrative services and it is intended
that KDI will pay all the administrative services fee that it receives from each
Fund to firms in the form of service fees. The effective administrative services
fee rate to be charged against all assets of each Fund while this procedure is
in effect will depend upon the proportion of Fund assets that is in accounts for
which a firm provides administrative services as well as, with respect to Class
A shares (except for the Mortgage and Short-Intermediate Government Funds), the
date when shares representing such assets were purchased. In addition, KDI may,
from time to time, from its own resources, pay certain firms additional amounts
for ongoing administrative services and assistance provided to their customers
and clients who are shareholders of the Funds.
 
CUSTODIAN, TRANSFER AGENT AND SHAREHOLDER SERVICE AGENT. Investors Fiduciary
Trust Company ("IFTC"), 801 Pennsylvania Avenue, Kansas City, Missouri 64105, as
custodian, and State Street Bank and Trust Company, 225 Franklin Street, Boston,
Massachusetts 02110, as sub-custodian, have custody of all securities and cash
of each Fund maintained in the United States. For Funds that invest in foreign
securities, The Chase Manhattan Bank, Chase MetroTech Center, Brooklyn, New York
11245, as custodian, has custody of all securities and cash of each Fund held
outside the United States. IFTC also is the Funds' transfer agent and
dividend-paying agent. Pursuant to a services agreement with IFTC, Kemper
Service Company ("KSvC"), an affiliate of ZKI, serves as "Shareholder Service
Agent" of the Funds and as such, performs all of IFTC's duties as transfer agent
and dividend-paying agent. For a description of shareholder service agent fees
payable to the Shareholder Service Agent, see "Investment Manager and
Underwriter" in the Statement of Additional Information.
 
PORTFOLIO TRANSACTIONS. ZKI and ZIML place all orders for purchases and sales of
a Fund's securities. Subject to seeking best execution of orders, ZKI and ZIML
may consider sales of shares of a Fund and other funds managed by ZKI or its
affiliates as a factor in selecting broker-dealers. See "Portfolio Transactions"
in the Statement of Additional Information.

DIVIDENDS AND TAXES
 
DIVIDENDS. Each Fund normally declares and distributes monthly dividends of net
investment income and distributes any net realized capital gains at least
annually.
 
Dividends paid by a Fund as to each class of its shares will be calculated in
the same manner, at the same time and on the same day. The level of income
dividends per share (as a percentage of net asset value) will be lower for Class
B and Class C shares than for Class A shares primarily as a result of the
distribution services fee applicable to Class B and Class C shares.
Distributions of capital gains, if any, will be paid in the same amount for each
class.
 
Income dividends and capital gain dividends, if any, of a Fund will be credited
to shareholder accounts in full and fractional shares of the same class of that
Fund at net asset value, except that, upon written request to the Shareholder
Service Agent, a shareholder may select one of the following options:
 
(1) To receive income and short-term capital gain dividends in cash and
    long-term capital gain dividends in shares of the same class at net asset
    value; or
 
(2) To receive income and capital gain dividends in cash.
 
Any dividends of a Fund that are reinvested normally will be reinvested in
shares of the same class of that same Fund. However, upon written request to the
Shareholder Service Agent, a shareholder may elect to have dividends of a Fund
invested in shares of the same class of another Kemper Fund at the net asset
value of such class of such other fund. See "Special Features--Class A
Shares--Combined Purchases" for a list of such other Kemper Funds. To use this
privilege of investing dividends of a Fund in shares of another Kemper Fund,
shareholders must maintain a minimum account value of $1,000 in the Fund
distributing the dividends. The Funds reinvest dividend checks (and future
dividends) in shares of that same Fund and class if checks are returned as
undeliverable. Dividends and other distributions in the aggregate amount of $10
or less are automatically reinvested in shares of the same Fund unless the
shareholder requests that such policy not be applied to the shareholder's
account.
 
TAXES.  Each Fund intends to continue to qualify as a regulated investment
company under Subchapter M of the Internal Revenue Code (the "Code") and, if so
qualified, will not be liable for federal income taxes to the extent its
earnings are distributed. Dividends derived from net investment income and net
short-term capital gains are taxable to shareholders as ordinary income and
long-term capital gain dividends are taxable to shareholders as long-term
capital gain regardless of how long the shares have been held and whether
received in cash or shares. Long-term capital gain dividends received by
individual shareholders are taxed at a maximum rate of 20% on gains realized by
a Fund from securities held more than 18 months and at a maximum rate of 28% on
gains realized by a Fund from securities held more than 12 months but not more
than 18 months. Dividends declared in October, November or December to
shareholders of record as of a date in one of those months and paid during the
following January are treated as paid on December 31 of the calendar year
declared. A portion of the dividends paid by the Diversified, High Yield or
Opportunity Funds may qualify for the dividends received deduction available to
corporate shareholders. However, it is anticipated that only a small portion, if
any, of the dividends paid by such Funds will so qualify. No portion of the
dividends paid by the Adjustable Rate, Government, Income and Capital, Mortgage
or Short-Intermediate Government Funds will qualify for the dividends received
deduction.
 
A dividend received shortly after the purchase of shares reduces the net asset
value of the shares by the amount of the dividend and, although in effect a
return of capital, will be taxable to the shareholder. If the net asset value of
shares were reduced below the shareholder's cost by dividends representing gains
realized on sales of securities, such dividends would be a return of investment
though taxable as stated above.
 
Fund dividends that are derived from interest on direct (but not guaranteed)
obligations of the U.S. Government and certain of its agencies and
instrumentalities may be exempt from state and local taxes in certain states. In
other states, arguments can be made that such distributions should be exempt
from state and local taxes based on federal law, 31 U.S.C. Section 3124, and the
U.S. Supreme Court's interpretation of that provision in AMERICAN
 
                                       37
<PAGE>   118
 
BANK AND TRUST CO. v. DALLAS COUNTY, 463 U.S. 855 (1983). Shareholders should
consult their tax advisers regarding the possible exclusion of such portion of
their dividends for state and local income tax purposes.
 
Each Fund is required by law to withhold 31% of taxable dividends and redemption
proceeds paid to certain shareholders who do not furnish a correct taxpayer
identification number (in the case of individuals, a social security number) and
in certain other circumstances. Trustees of qualified retirement plans and
403(b)(7) accounts are required by law to withhold 20% of the taxable portion of
any distribution that is eligible to be "rolled over." The 20% withholding
requirement does not apply to distributions from Individual Retirement Accounts
("IRAs") or any part of a distribution that is transferred directly to another
qualified retirement plan, 403(b)(7) account, or IRA. Shareholders should
consult with their tax advisers regarding the 20% withholding requirement.
 
After each transaction, shareholders will receive a confirmation statement
giving complete details of the transaction except that statements will be sent
quarterly for transactions involving dividend reinvestment and periodic
investment and redemption programs. Information for income tax purposes,
including information regarding any foreign taxes and credits, will be provided
after the end of the calendar year. Shareholders are encouraged to retain copies
of their account confirmation statements or year-end statements for tax
reporting purposes, including information regarding any foreign taxes and
credits. However, those who have incomplete records may obtain historical
account transaction information at a reasonable fee.
 
When more than one shareholder resides at the same address, certain reports and
communications to be delivered to such shareholders may be combined in the same
mailing package, and certain duplicate reports and communications may be
eliminated. Similarly, account statements to be sent to such shareholders may be
combined in the same mailing package or consolidated into a single statement.
However, a shareholder may request that the foregoing policies not be applied to
the shareholder's account.
 
NET ASSET VALUE
 
For each Fund, the net asset value per share is determined separately for each
class by dividing the value of the Fund's net assets attributable to that class
by the number of shares of that class outstanding. The per share net asset value
of the Class B and Class C shares of a Fund will generally be lower than that of
the Class A shares of the Fund because of the higher expenses borne by the Class
B and Class C shares. Fixed income securities are valued by using market
quotations, or independent pricing services that use prices provided by market
makers or estimates of market values obtained from yield data relating to
instruments or securities with similar characteristics. Portfolio securities
that are primarily traded on a domestic securities exchange or securities listed
on the NASDAQ National Market are valued at the last sale price on the exchange
or market where primarily traded or listed or, if there is no recent sale price
available, at the last current bid quotation. Portfolio securities that are
primarily traded on foreign securities exchanges are generally valued at the
preceding closing values of such securities on their respective exchanges where
primarily traded. A security that is listed or traded on more than one exchange
is valued at the quotation on the exchange determined to be the primary market
for such security by the Board of Trustees or its delegates. Securities not so
traded or listed are valued at the last current bid quotation if market
quotations are available. Equity options are valued at the last sale price
unless the bid price is higher or the ask price is lower, in which event such
bid or asked price is used. Exchange traded fixed income options, financial
futures and options thereon are valued at the settlement price established each
day by the board of trade or exchange on which they are traded. Over-the-counter
traded options, swap agreements and swap-related products are valued based upon
current prices provided by market makers. Financial futures and options thereon
are valued at the settlement price established each day by the board of trade or
exchange on which they are traded. Other securities and assets are valued at
fair value as determined in good faith by the Board of Trustees. Because of the
need to obtain prices as of the close of trading on various exchanges throughout
the world, the calculation of net asset value of a Fund investing in foreign
securities does not necessarily take place contemporaneously with the
determination of the prices of the Fund's foreign securities, which may be made
prior to the determination of net asset value. For purposes of determining the
net asset value of a Fund investing

                                       38
<PAGE>   119
 
in foreign securities, all assets and liabilities initially expressed in foreign
currency values will be converted into U.S. Dollar values at the mean between
the bid and offered quotations of such currencies against U.S. Dollars as last
quoted by a recognized dealer. If an event were to occur, after the value of a
security was so established but before the net asset value per share was
determined, which was likely to materially change the net asset value, then that
security would be valued using fair value determinations by the Board of
Trustees or its delegates. On each day the New York Stock Exchange (the
"Exchange") is open for trading, the net asset value is determined as of the
earlier of 3:00 p.m. Chicago time or the close of the Exchange.
 
PURCHASE OF SHARES
 
ALTERNATIVE PURCHASE ARRANGEMENTS. Class A shares of each Fund are sold to
investors subject to an initial sales charge. Class B shares are sold without an
initial sales charge but are subject to higher ongoing expenses than Class A
shares and a contingent deferred sales charge payable upon certain redemptions.
Class B shares automatically convert to Class A shares six years after issuance.
Class C shares are sold without an initial sales charge but are subject to
higher ongoing expenses than Class A shares, are subject to a contingent
deferred sales charge payable upon certain redemptions within the first year
following purchase, and do not convert into another class. When placing purchase
orders, investors must specify whether the order is for Class A, Class B or
Class C shares.
 
The primary distinctions among the classes of each Fund's shares lie in their
initial and contingent deferred sales charge structures and in their ongoing
expenses, including asset-based sales charges in the form of Rule 12b-1
distribution fees. These differences are summarized in the table below. See,
also, "Summary of Expenses." Each class has distinct advantages and
disadvantages for different investors, and investors may choose the class that
best suits their circumstances and objectives.

The minimum initial investment for each Fund is $1,000 and the minimum
subsequent investment is $100. The minimum initial investment for an Individual
Retirement Account is $250 and the minimum subsequent investment is $50. Under
an automatic investment plan, such as Bank Direct Deposit, Payroll Direct
Deposit or Government Direct Deposit, the minimum initial and subsequent
investment is $50. These minimum amounts may be changed at any time in
management's discretion. In order to begin accruing income dividends as soon as
possible, purchasers may wire payment to United Missouri Bank of Kansas City,
N.A., 10th and Grand Avenue, Kansas City, Missouri 64106.
 
Share certificates will not be issued unless requested in writing and may not be
available for certain types of account registrations. It is recommended that
investors not request share certificates unless needed for a specific purpose.
You cannot redeem shares by telephone or wire transfer or use the telephone
exchange privilege if share certificates have been issued. A lost or destroyed
certificate is difficult to replace and can be expensive to the shareholder (a
bond worth 2% or more of the certificate value is normally required).

 ** Redemption of shares may be subject to a contingent deferred sales charge as
    discussed below.
*** Commission is payable by KDI as discussed below.
 
Each Fund receives the entire net asset value of all its Class A shares sold.
KDI, the Funds' principal underwriter, retains the sales charge on sales of
Class A shares from which it allows discounts from the applicable public
offering price to investment dealers, which discounts are uniform for all
dealers in the United States and its territories. The normal discount allowed to
dealers is set forth in the above table. Upon notice to all dealers with whom it
has sales agreements, KDI may reallow up to the full applicable sales charge, as
shown in the above table, during periods and for transactions specified in such
notice and such reallowances may be based upon attainment of minimum sales
levels. During periods when 90% or more of the sales charge is reallowed, such
dealers may be deemed to be underwriters as that term is defined in the
Securities Act of 1933.
 
Class A shares of a Fund may be purchased at net asset value to the extent that
the amount invested represents the net proceeds from a redemption of shares of a
mutual fund for which ZKI or an affiliate does not serve as investment manager
("non-Kemper Fund") provided that: (a) the investor has previously paid either
an initial sales charge in connection with the purchase of the non-Kemper Fund
shares redeemed or a contingent deferred
 
                                       40
<PAGE>   121
 
sales charge in connection with the redemption of the non-Kemper Fund shares,
and (b) the purchase of Fund shares is made within 90 days after the date of
such redemption. To make such a purchase at net asset value, the investor or the
investor's dealer must, at the time of purchase, submit a request that the
purchase be processed at net asset value pursuant to this privilege. KDI may in
its discretion compensate firms for sales of Class A shares under this privilege
at a commission rate of .50% of the amount of Class A shares purchased. The
redemption of the shares of the non-Kemper fund is, for federal income tax
purposes, a sale upon which a gain or loss may be realized.
 
Class A shares of a Fund may be purchased at net asset value by: (a) any
purchaser provided that the amount invested in such Fund or other Kemper Mutual
Funds listed under "Special Features--Class A Shares--Combined Purchases" totals
at least $1,000,000 including purchases of Class A shares pursuant to the
"Combined Purchases," "Letter of Intent" and "Cumulative Discount" features
described under "Special Features;" or (b) a participant-directed qualified
retirement plan described in Code Section 401(a) or a participant-directed
non-qualified deferred compensation plan described in Code Section 457 or a
participant-directed qualified retirement plan described in Code Section
403(b)(7) which is not sponsored by a K-12 school district, provided in each
case that such plan has not less than 200 eligible employees (the "Large Order
NAV Purchase Privilege"). Redemption within two years of shares purchased under
the Large Order NAV Purchase Privilege may be subject to a contingent deferred
sales charge. See "Redemption or Repurchase of Shares--Contingent Deferred Sales
Charge--Large Order NAV Purchase Privilege."
 
KDI may in its discretion compensate investment dealers or other financial
services firms in connection with the sale of Class A shares of a Fund at net
asset value in accordance with the Large Order NAV Purchase Privilege up to the
following amounts: 1.00% of the net asset value of shares sold on amounts up to
$5 million, .50% on the next $45 million and .25% on amounts over $50 million.
The commission schedule will be reset on a calendar year basis for sales of
shares pursuant to the Large Order NAV Purchase Privilege to employer sponsored
employee benefit plans using the subaccount record keeping system made available
through KSvC. For purposes of determining the appropriate commission percentage
to be applied to a particular sale, KDI will consider the cumulative amount
invested by the purchaser in a Fund and other Kemper Mutual Funds listed under
"Special Features--Class A Shares--Combined Purchases," including purchases
pursuant to the "Combined Purchases," "Letter of Intent" and "Cumulative
Discount" features referred to above. The privilege of purchasing Class A shares
of a Fund at net asset value under the Large Order NAV Purchase Privilege is not
available if another net asset value purchase privilege also applies.
 
Effective on February 1, 1996, Class A shares of a Fund or any other Kemper
Mutual Fund listed under "Special Features--Class A Shares--Combined Purchases"
may be purchased at net asset value in any amount by members of the plaintiff
class in the proceeding known as HOWARD AND AUDREY TABANKIN, ET AL. V. KEMPER
SHORT-TERM GLOBAL INCOME FUND, ET AL., Case No. 93 C 5231 (N.D. IL). This
privilege is generally non-transferrable and continues for the lifetime of
individual class members and for a ten year period for non-individual class
members. To make a purchase at net asset value under this privilege, the
investor must, at the time of purchase, submit a written request that the
purchase be processed at net asset value pursuant to this privilege specifically
identifying the purchaser as a member of the "Tabankin Class." Shares purchased
under this privilege will be maintained in a separate account that includes only
shares purchased under this privilege. For more details concerning this
privilege, class members should refer to the Notice of (1) Proposed Settlement
with Defendants; and (2) Hearing to Determine Fairness of Proposed Settlement,
dated August 31, 1995, issued in connection with the aforementioned court
proceeding. For sales of Fund shares at net asset value pursuant to this
privilege, KDI may at its discretion pay investment dealers and other financial
services firms a concession, payable quarterly, at an annual rate of up to .25%
of net assets attributable to such shares maintained and serviced by the firm. A
firm becomes eligible for the concession based upon assets in accounts
attributable to shares purchased under this privilege in the month after the
month of purchase and the concession continues until terminated by KDI. The
privilege of purchasing Class A shares of a Fund at net asset value under this
privilege is not available if another net asset value purchase privilege also
applies.

Class A shares may be sold at net asset value in any amount to: (a) officers,
trustees, directors, employees (including retirees) and sales representatives of
a Fund, its investment manager, its principal underwriter or certain affiliated
companies, for themselves or members of their families; (b) registered
representatives and employees of broker-dealers having selling group agreements
with KDI and officers, directors and employees of service agents of the Funds,
for themselves or their spouses or dependent children; (c) shareholders who
owned shares of Kemper Value Fund, Inc. ("KVF") on September 8, 1995, and have
continuously owned shares of KVF (or a Kemper Fund acquired by exchange of KVF
shares) since that date, for themselves or members of their families, and (d)
any trust or pension, profit-sharing or other benefit plan for only such
persons. Class A shares may be sold at net asset value in any amount to selected
employees (including their spouses and dependent children) of banks and other
financial services firms that provide administrative services related to order
placement and payment to facilitate transactions in shares of the Funds for
their clients pursuant to an agreement with KDI or one of its affiliates. Only
those employees of such banks and other firms who as part of their usual duties
provide services related to transactions in Fund Class A shares may purchase
Fund shares at net asset value hereunder. Class A shares may be sold at net
asset value in any amount to unit investment trusts sponsored by Ranson &
Associates, Inc. In addition, unitholders of unit investment trusts sponsored by
Ranson & Associates, Inc. or its predecessors may purchase a Fund's Class A
shares at net asset value through reinvestment programs described in the
prospectuses of such trusts that have such programs. Class A shares of a Fund
may be sold at net asset value through certain investment advisers registered
under the Investment Advisers Act of 1940 and other financial services firms
that adhere to certain standards established by KDI, including a requirement
that such shares be sold for the benefit of their clients participating in an
investment advisory program under which such clients pay a fee to the investment
adviser or other firm for portfolio management and other services. Such shares
are sold for investment purposes and on the condition that they will not be
resold except through redemption or repurchase by the Funds. The Funds may also
issue Class A shares at net asset value in connection with the acquisition of
the assets of or merger or consolidation with another investment company, or to
shareholders in connection with the investment or reinvestment of income and
capital gain dividends.
 
Class A shares of a Fund may be purchased at net asset value by persons who
purchase such shares through bank trust departments that process such trades
through an automated, integrated mutual fund clearing program provided by a
third party clearing firm.
 
Class A shares of a Fund may be purchased at net asset value in any amount by
certain professionals who assist in the promotion of Kemper Funds pursuant to
personal services contracts with KDI, for themselves or members of their
families. KDI in its discretion may compensate financial services firms for
sales of Class A shares under this privilege at a commission rate of .50% of the
amount of Class A shares purchased.
 
Class A shares of a Fund may be purchased at net asset value by persons who
purchase shares of the Fund through KDI as part of an automated billing and wage
deduction program administered by RewardsPlus of America for the benefit of
employees of participating employer groups.
 
The sales charge scale is applicable to purchases made at one time by any
"purchaser" which includes: an individual; or an individual, his or her spouse
and children under the age of 21; or a trustee or other fiduciary of a single
trust estate or single fiduciary account; or an organization exempt from federal
income tax under Section 501(c)(3) or (13) of the Code; or a pension,
profit-sharing or other employee benefit plan whether or not qualified under
Section 401 of the Code; or other organized group of persons whether
incorporated or not, provided the organization has been in existence for at
least six months and has some purpose other than the purchase of redeemable
securities of a registered investment company at a discount. In order to qualify
for a lower sales charge, all orders from an organized group will have to be
placed through a single investment dealer or other firm and identified as
originating from a qualifying purchaser.
 
DEFERRED SALES CHARGE ALTERNATIVE--CLASS B SHARES. Investors choosing the
deferred sales charge alternative may purchase Class B shares at net asset value
per share without any sales charge at the time of purchase. Since Class B shares
are being sold without an initial sales charge, the full amount of the
investor's purchase payment will be invested in Class B shares for his or her
account. A contingent deferred sales charge may be imposed upon
 
                                       42

redemption of Class B shares. See "Redemption or Repurchase of
Shares--Contingent Deferred Sales Charge--Class B Shares."
 
KDI compensates firms for sales of Class B shares at the time of sale at a
commission rate of up to 3.75% of the amount of Class B shares purchased. KDI is
compensated by each Fund for services as distributor and principal underwriter
for Class B shares. See "Investment Manager and Underwriter."
 
Class B shares of a Fund will automatically convert to Class A shares of the
same Fund six years after issuance on the basis of the relative net asset value
per share. Class B shareholders of the Funds who originally acquired their
shares as Initial Shares of Kemper Portfolios, formerly known as Kemper
Investment Portfolios ("KIP"), hold them subject to the same conversion period
schedule as that of their KIP Portfolio. Class B shares originally representing
Initial Shares of a KIP Portfolio will automatically convert to Class A shares
of the applicable Fund six years after issuance of the Initial Shares for shares
issued on or after February 1, 1991 and seven years after issuance of the
Initial Shares for shares issued before February 1, 1991. The purpose of the
conversion feature is to relieve holders of Class B shares from the distribution
services fee when they have been outstanding long enough for KDI to have been
compensated for distribution related expenses. For purposes of conversion to
Class A shares, shares purchased through the reinvestment of dividends and other
distributions paid with respect to Class B shares in a shareholder's Fund
account will be converted to Class A shares on a pro rata basis.
 
PURCHASE OF CLASS C SHARES. The public offering price of the Class C shares of a
Fund is the next determined net asset value. No initial sales charge is imposed.
Since Class C shares are sold without an initial sales charge, the full amount
of the investor's purchase payment will be invested in Class C shares for his or
her account. A contingent deferred sales charge may be imposed upon the
redemption of Class C shares if they are redeemed within one year of purchase.
See "Redemption or Repurchase of Shares--Contingent Deferred Sales Charge--Class
C Shares." KDI currently advances to firms the first year distribution fee at a
rate of .75% of the purchase price of such shares. For periods after the first
year, KDI currently intends to pay firms for sales of Class C shares a
distribution fee, payable quarterly, at an annual rate of .75% of net assets
attributable to Class C shares maintained and serviced by the firm. KDI is
compensated by each Fund for services as distributor and principal underwriter
for Class C shares. See "Investment Manager and Underwriter."
 
WHICH ARRANGEMENT IS BETTER FOR YOU? The decision as to which class of shares
provides a more suitable investment for an investor depends on a number of
factors, including the amount and intended length of the investment. Investors
making investments that qualify for reduced sales charges might consider Class A
shares. Investors who prefer not to pay an initial sales charge and who plan to
hold their investment for more than six years might consider Class B shares.
Investors who prefer not to pay an initial sales charge but who plan to redeem
their shares within six years might consider Class C shares. Orders for Class B
shares or Class C shares for $500,000 or more will be declined. Orders for Class
B shares or Class C shares by employer sponsored employee benefit plans using
the subaccount record keeping system made available through the Shareholder
Service Agent will be invested instead in Class A shares at net asset value
where the combined subaccount value in a Fund or other Kemper Mutual Funds
listed under "Special Features--Class A Shares--Combined Purchases" is in excess
of $5 million including purchases pursuant to the "Combined Purchases," "Letter
of Intent" and "Cumulative Discount" features described under "Special
Features." For more information about the three sales arrangements, consult your
financial representative or the Shareholder Service Agent. Financial services
firms may receive different compensation depending upon which class of shares
they sell.
 
GENERAL. Banks and other financial services firms may provide administrative
services related to order placement and payment to facilitate transactions in
shares of a Fund for their clients, and KDI may pay them a transaction fee up to
the level of the discount or commission allowable or payable to dealers, as
described above. Banks are currently prohibited under the Glass-Steagall Act
from providing certain underwriting or distribution services. Banks or other
financial services firms may be subject to various state laws regarding the
services described above and may be required to register as dealers pursuant to
state law. If banking firms were prohibited from acting in any capacity or
providing any of the described services, management would consider what action,
if any, would be
 
                                       43
<PAGE>   124
 
appropriate. KDI does not believe that termination of a relationship with a bank
would result in any material adverse consequences to a Fund.
 
KDI may, from time to time, pay or allow to firms a 1% commission on the amount
of shares of a Fund sold by the firm under the following conditions: (i) the
purchased shares are held in a Kemper IRA account, (ii) the shares are purchased
as a direct "roll over" of a distribution from a qualified retirement plan
account maintained on a participant subaccount record keeping system provided by
KSvC, (iii) the registered representative placing the trade is a member of
ProStar, a group of persons designated by KSvC in acknowledgement of their
dedication to the employee benefit plan area and (iv) the purchase is not
otherwise subject to a commission.
 
In addition to the discounts or commissions described above, KDI will, from time
to time, pay or allow additional discounts, commissions or promotional
incentives, in the form of cash or other compensation, to firms that sell shares
of the Funds. Non-cash compensation includes luxury merchandise and trips to
luxury resorts. In some instances, such discounts, commissions or other
incentives will be offered only to certain firms that sell or are expected to
sell during specified time periods certain minimum amounts of shares of the
Funds or other funds underwritten by KDI.
 
Orders for the purchase of shares of a Fund will be confirmed at a price based
on the net asset value of that Fund next determined after receipt by KDI of the
order accompanied by payment. However, orders received by dealers or other
financial services firms prior to the determination of net asset value (see "Net
Asset Value") and received by KDI prior to the close of its business day will be
confirmed at a price based on the net asset value effective on that day ("trade
date"). The Funds reserve the right to determine the net asset value more
frequently than once a day if deemed desirable. Dealers and other financial
services firms are obligated to transmit orders promptly. Collection may take
significantly longer for a check drawn on a foreign bank than for a check drawn
on a domestic bank. Therefore, if an order is accompanied by a check drawn on a
foreign bank, funds must normally be collected before shares will be purchased.
See "Purchase and Redemption of Shares" in the Statement of Additional
Information.
 
Investment dealers and other firms provide varying arrangements for their
clients to purchase and redeem the Funds' shares. Some may establish higher
minimum investment requirements than set forth above. Firms may arrange with
their clients for other investment or administrative services. Such firms may
independently establish and charge additional amounts to their clients for such
services, which charges would reduce the clients' return. Firms also may hold
the Funds' shares in nominee or street name as agent for and on behalf of their
customers. In such instances, the Funds' transfer agent will have no information
with respect to or control over the accounts of specific shareholders. Such
shareholders may obtain access to their accounts and information about their
accounts only from their firm. Certain of these firms may receive compensation
from the Funds through the Shareholder Service Agent for recordkeeping and other
expenses relating to these nominee accounts. In addition, certain privileges
with respect to the purchase and redemption of shares or the reinvestment of
dividends may not be available through such firms. Some firms may participate in
a program allowing them access to their clients' accounts for servicing
including, without limitation, transfers of registration and dividend payee
changes; and may perform functions such as generation of confirmation statements
and disbursement of cash dividends. Such firms, including affiliates of KDI, may
receive compensation from the Funds through the Shareholder Service Agent for
these services. This prospectus should be read in connection with such firms'
material regarding their fees and services.
 
The Funds reserve the right to withdraw all or any part of the offering made by
this prospectus and to reject purchase orders. Also, from time to time, each
Fund may temporarily suspend the offering of any class of its shares to new
investors. During the period of such suspension, persons who are already
shareholders of such class of the Fund normally are permitted to continue to
purchase additional shares of such class and to have dividends reinvested.
 
Shareholders should direct their inquiries to KSvC, 811 Main Street, Kansas
City, Missouri 64105-2005 or to the firm from which they received this
prospectus.

REDEMPTION OR REPURCHASE OF SHARES
 
GENERAL. Any shareholder may require a Fund to redeem his or her shares. When
shares are held for the account of a shareholder by the Funds' transfer agent,
the shareholder may redeem them by sending a written request with signatures
guaranteed to Kemper Mutual Funds, Attention: Redemption Department, P.O. Box
419557, Kansas City, Missouri 64141-6557. When certificates for shares have been
issued, they must be mailed to or deposited with the Shareholder Service Agent,
along with a duly endorsed stock power and accompanied by a written request for
redemption. Redemption requests and a stock power must be endorsed by the
account holder with signatures guaranteed by a commercial bank, trust company,
savings and loan association, federal savings bank, member firm of a national
securities exchange or other eligible financial institution. The redemption
request and stock power must be signed exactly as the account is registered
including any special capacity of the registered owner. Additional documentation
may be requested, and a signature guarantee is normally required, from
institutional and fiduciary account holders, such as corporations, custodians
(e.g., under the Uniform Transfers to Minors Act), executors, administrators,
trustees or guardians.
 
The redemption price for shares of a Fund will be the net asset value per share
of that Fund next determined following receipt by the Shareholder Service Agent
of a properly executed request with any required documents as described above.
Payment for shares redeemed will be made in cash as promptly as practicable but
in no event later than seven days after receipt of a properly executed request
accompanied by any outstanding share certificates in proper form for transfer.
When a Fund is asked to redeem shares for which it may not have yet received
good payment (i.e., purchases by check, EXPRESS-Transfer or Bank Direct
Deposit), it may delay transmittal of redemption proceeds until it has
determined that collected funds have been received for the purchase of such
shares, which will be up to 10 days from receipt by a Fund of the purchase
amount. The redemption within two years of Class A shares purchased at net asset
value under the Large Order NAV Purchase Privilege may be subject to a
contingent deferred sales charge (see "Purchase of Shares--Initial Sales Charge
Alternative--Class A Shares"), the redemption of Class B shares within six years
may be subject to a contingent deferred sales charge (see "Contingent Deferred
Sales Charge--Class B Shares" below), and the redemption of Class C shares
within the first year following purchase may be subject to a contingent deferred
sales charge (see "Contingent Deferred Sales Charge--Class C Shares" below).
 
Because of the high cost of maintaining small accounts, effective January 1998,
the Funds may assess a quarterly fee of $9 on an account with a balance below
$1,000 for the quarter. The fee will not apply to accounts enrolled in an
automatic investment program, Individual Retirement Accounts or employer
sponsored employee benefit plans using the subaccount record keeping system made
available through the Shareholder Service Agent.
 
Shareholders can request the following telephone privileges: expedited wire
transfer redemptions and EXPRESS-Transfer transactions (see "Special Features")
and exchange transactions for individual and institutional accounts and
pre-authorized telephone redemption transactions for certain institutional
accounts. Shareholders may choose these privileges on the account application or
by contacting the Shareholder Service Agent for appropriate instructions. Please
note that the telephone exchange privilege is automatic unless the shareholder
refuses it on the account application. A Fund or its agents may be liable for
any losses, expenses or costs arising out of fraudulent or unauthorized
telephone requests pursuant to these privileges unless the Fund or its agents
reasonably believe, based upon reasonable verification procedures, that the
telephonic instructions are genuine. The SHAREHOLDER WILL BEAR THE RISK OF LOSS,
including loss resulting from fraudulent or unauthorized transactions, as long
as the reasonable verification procedures are followed. The verification
procedures include recording instructions, requiring certain identifying
information before acting upon instructions and sending written confirmations.
 
TELEPHONE REDEMPTIONS. If the proceeds of the redemption (prior to the
imposition of any contingent deferred sales charge) are $50,000 or less and the
proceeds are payable to the shareholder of record at the address of record,
normally a telephone request or a written request by any one account holder
without a signature guarantee is sufficient for redemptions by individual or
joint account holders, and trust, executor and guardian account holders
(excluding custodial accounts for gifts and transfers to minors), provided the
trustee, executor
 
                                       45
<PAGE>   126
 
or guardian is named in the account registration. Other institutional account
holders and guardian account holders of custodial accounts for gifts and
transfers to minors may exercise this special privilege of redeeming shares by
telephone request or written request without signature guarantee subject to the
same conditions as individual account holders and subject to the limitations on
liability described under "General" above, provided that this privilege has been
pre-authorized by the institutional account holder or guardian account holder by
written instruction to the Shareholder Service Agent with signatures guaranteed.
Telephone requests may be made by calling 1-800-621-1048. Shares purchased by
check or through EXPRESS-Transfer or Bank Direct Deposit may not be redeemed
under this privilege of redeeming shares by telephone request until such shares
have been owned for at least 10 days. This privilege of redeeming shares by
telephone request or by written request without a signature guarantee may not be
used to redeem shares held in certificated form and may not be used if the
shareholder's account has had an address change within 30 days of the redemption
request. During periods when it is difficult to contact the Shareholder Service
Agent by telephone, it may be difficult to use the telephone redemption
privilege, although investors can still redeem by mail. The Funds reserve the
right to terminate or modify this privilege at any time.
 
REPURCHASES (CONFIRMED REDEMPTIONS). A request for repurchase may be
communicated by a shareholder through a securities dealer or other financial
services firm to KDI, which each Fund has authorized to act as its agent. There
is no charge by KDI with respect to repurchases; however, dealers or other firms
may charge customary commissions for their services. Dealers and other financial
services firms are obligated to transmit orders promptly. The repurchase price
will be the net asset value of the Fund next determined after receipt of a
request by KDI. However, requests for repurchases received by dealers or other
firms prior to the determination of net asset value (see "Net Asset Value") and
received by KDI prior to the close of KDI's business day will be confirmed at
the net asset value effective on that day. The offer to repurchase may be
suspended at any time. Requirements as to stock powers, certificates, payments
and delay of payments are the same as for redemptions.
 
EXPEDITED WIRE TRANSFER REDEMPTIONS. If the account holder has given
authorization for expedited wire redemption to the account holder's brokerage or
bank account, shares of a Fund can be redeemed and proceeds sent by federal wire
transfer to a single previously designated account. Requests received by the
Shareholder Service Agent prior to the determination of net asset value will
result in shares being redeemed that day at the net asset value of the Fund
effective on that day and normally the proceeds will be sent to the designated
account the following business day. Delivery of the proceeds of a wire
redemption request of $250,000 or more may be delayed by the Fund for up to
seven days if ZKI deems it appropriate under then current market conditions.
Once authorization is on file, the Shareholder Service Agent will honor requests
by telephone at 1-800-621-1048 or in writing, subject to the limitations on
liability described under "General" above. The Funds are not responsible for the
efficiency of the federal wire system or the account holder's financial services
firm or bank. The Funds currently do not charge the account holder for wire
transfers. The account holder is responsible for any charges imposed by the
account holder's firm or bank. There is a $1,000 wire redemption minimum
(including any contingent deferred sales charge). To change the designated
account to receive wire redemption proceeds, send a written request to the
Shareholder Service Agent with signatures guaranteed as described above or
contact the firm through which shares of the Fund were purchased. Shares
purchased by check or through EXPRESS-Transfer or Bank Direct Deposit may not be
redeemed by wire transfer until such shares have been owned for at least 10
days. Account holders may not use this privilege to redeem shares held in
certificated form. During periods when it is difficult to contact the
Shareholder Service Agent by telephone, it may be difficult to use the expedited
redemption privilege. The Funds reserve the right to terminate or modify this
privilege at any time.
 
CONTINGENT DEFERRED SALES CHARGE--LARGE ORDER NAV PURCHASE PRIVILEGE. A
contingent deferred sales charge may be imposed upon redemption of Class A
shares that are purchased under the Large Order NAV Purchase Privilege as
follows: 1% if they are redeemed within one year of purchase and .50% if they
are redeemed during the second year following purchase. The charge will not be
imposed upon redemption of reinvested dividends or share appreciation. The
charge is applied to the value of the shares redeemed excluding amounts not
subject to the charge. The contingent deferred sales charge will be waived in
the event of: (a) redemptions by a participant-directed qualified retirement
plan described in Code Section 401(a) or a participant-directed non-qualified
 
                                       46
<PAGE>   127
 
deferred compensation plan described in Code Section 457 or a
participant-directed qualified retirement plan described in Code Section
403(b)(7) which is not sponsored by a K-12 school district; (b) redemptions by
employer sponsored employee benefit plans using the subaccount record keeping
system made available through the Shareholder Service Agent; (c) redemption of
shares of a shareholder (including a registered joint owner) who has died; (d)
redemption of shares of a shareholder (including a registered joint owner) who
after purchase of the shares being redeemed becomes totally disabled (as
evidenced by a determination by the federal Social Security Administration); (e)
redemptions under a Fund's Systematic Withdrawal Plan at a maximum of 10% per
year of the net asset value of the account; and (f) redemptions of shares whose
dealer of record at the time of the investment notifies KDI that the dealer
waives the commission applicable to such Large Order NAV Purchase.
 
CONTINGENT DEFERRED SALES CHARGE--CLASS B SHARES. A contingent deferred sales
charge may be imposed upon redemption of Class B shares. There is no such charge
upon redemption of any share appreciation or reinvested dividends on Class B
shares. The charge is computed at the following rates applied to the value of
the shares redeemed excluding amounts not subject to the charge.

The contingent deferred sales charge will be waived: (a) in the event of the
total disability (as evidenced by a determination by the federal Social Security
Administration) of the shareholder (including a registered joint owner)
occurring after the purchase of the shares being redeemed, (b) in the event of
the death of the shareholder (including a registered joint owner), (c) for
redemptions made pursuant to a systematic withdrawal plan (see "Special
Features--Systematic Withdrawal Plan" below) and (d) for redemptions made
pursuant to any IRA systematic withdrawal based on the shareholder's life
expectancy including, but not limited to, substantially equal periodic payments
described in Internal Revenue Code Section 72(t)(2)(A)(iv) prior to age 59 1/2;
and (e) for redemptions to satisfy required minimum distributions after age
70 1/2 from an IRA account (with the maximum amount subject to this waiver being
based only upon the shareholder's Kemper IRA accounts). The contingent deferred
sales charge will also be waived in connection with the following redemptions of
shares held by employer sponsored employee benefit plans maintained on the
subaccount record keeping system made available by the Shareholder Service
Agent: (a) redemptions to satisfy participant loan advances (note that loan
repayments constitute new purchases for purposes of the contingent deferred
sales charge and the conversion privilege), (b) redemptions in connection with
retirement distributions (limited at any one time to
 
                                       47
<PAGE>   128
 
10% of the total value of plan assets invested in a Fund), (c) redemptions in
connection with distributions qualifying under the hardship provisions of the
Internal Revenue Code and (d) redemptions representing returns of excess
contributions to such plans.
 
CONTINGENT DEFERRED SALES CHARGE--CLASS C SHARES. A contingent deferred sales
charge of 1% may be imposed upon redemption of Class C shares if they are
redeemed within one year of purchase. The charge will not be imposed upon
redemption of reinvested dividends or share appreciation. The charge is applied
to the value of the shares redeemed excluding amounts not subject to the charge.
The contingent deferred sales charge will be waived: (a) in the event of the
total disability (as evidenced by a determination by the federal Social Security
Administration) of the shareholder (including a registered joint owner)
occurring after the purchase of the shares being redeemed, (b) in the event of
the death of the shareholder (including a registered joint owner), (c) for
redemptions made pursuant to a systematic withdrawal plan (limited to 10% of the
net asset value of the account during the first year, see "Special
Features--Systematic Withdrawal Plan"), (d) for redemptions made pursuant to any
IRA systematic withdrawal based on the shareholder's life expectancy including,
but not limited to, substantially equal periodic payments described in Internal
Revenue Code Section 72(t)(2)(A)(iv) prior to age 59 1/2, (e) for redemptions to
satisfy required minimum distributions after age 70 1/2 from an IRA account
(with the maximum amount subject to this waiver being based only upon the
shareholder's Kemper IRA accounts), (f) for any participant-directed redemption
of shares held by employer sponsored employee benefit plans maintained on the
subaccount record keeping system made available by the Shareholder Service Agent
and (g) redemption of shares by an employer sponsored employee benefit plan that
offers funds in addition to Kemper Funds and whose dealer of record has waived
the advance of the first year administrative service and distribution fees
applicable to such shares and agrees to receive such fees quarterly.
 
CONTINGENT DEFERRED SALES CHARGE--GENERAL. The following example will illustrate
the operation of the contingent deferred sales charge. Assume that an investor
makes a single purchase of $10,000 of a Fund's Class B shares and that 16 months
later the value of the shares has grown by $1,000 through reinvested dividends
and by an additional $1,000 in appreciation to a total of $12,000. If the
investor were then to redeem the entire $12,000 in share value, the contingent
deferred sales charge would be payable only with respect to $10,000 because
neither the $1,000 of reinvested dividends nor the $1,000 of share appreciation
is subject to the charge. The charge would be at the rate of 3% ($300) because
it was in the second year after the purchase was made.
 
The rate of the contingent deferred sales charge is determined by the length of
the period of ownership. Investments are tracked on a monthly basis. The period
of ownership for this purpose begins the first day of the month in which the
order for the investment is received. For example, an investment made in
December, 1997 will be eligible for the second year's charge if redeemed on or
after December 1, 1998. In the event no specific order is requested, the
redemption will be made first from shares representing reinvested dividends and
then from the earliest purchase of shares. KDI receives any contingent deferred
sales charge directly.
 
REINVESTMENT PRIVILEGE. A shareholder who has redeemed Class A shares of a Fund
or any other Kemper Mutual Fund listed under "Special Features--Class A
Shares--Combined Purchases" (other than shares of the Kemper Cash Reserves Fund
purchased directly at net asset value) may reinvest up to the full amount
redeemed at net asset value at the time of the reinvestment in Class A shares of
a Fund or of the other listed Kemper Mutual Funds. A shareholder of a Fund or
other Kemper Mutual Fund who redeems Class A shares purchased under the Large
Order NAV Purchase Privilege (see "Purchase of Shares--Initial Sales Charge
Alternative--Class A Shares") or Class B shares or Class C shares and incurs a
contingent deferred sales charge may reinvest up to the full amount redeemed at
net asset value at the time of the reinvestment in Class A shares, Class B
shares or Class C shares, as the case may be, of a Fund or of other Kemper
Mutual Funds. The amount of any contingent deferred sales charge also will be
reinvested. These reinvested shares will retain their original cost and purchase
date for purposes of the contingent deferred sales charge. Also, a holder of
Class B shares who has redeemed shares may reinvest up to the full amount
redeemed, less any applicable contingent deferred sales charge that may have
been imposed upon the redemption of such shares, at net asset value in Class A
shares of a Fund or of the other Kemper Mutual Funds listed under "Special
Features--Class A Shares--Combined Purchases." Purchases through

the reinvestment privilege are subject to the minimum investment requirements
applicable to the shares being purchased and may only be made for Kemper Mutual
Funds available for sale in the shareholder's state of residence as listed under
"Special Features--Exchange Privilege." The reinvestment privilege can be used
only once as to any specific shares and reinvestment must be effected within six
months of the redemption. If a loss is realized on the redemption of a Funds'
shares, the reinvestment in the same Fund may be subject to the "wash sale"
rules if made within 30 days of the redemption, resulting in a postponement of
the recognition of such loss for federal income tax purposes. The reinvestment
privilege may be terminated or modified at any time.

which are not considered "Kemper Mutual Funds" for purposes hereof. For purposes
of the Combined Purchases feature described above as well as for the Letter of
Intent and Cumulative Discount features described below, employer sponsored
employee benefit plans using the subaccount record keeping system made available
through the Shareholder Service Agent may include: (a) Money Market Funds as
"Kemper Mutual Funds," (b) all classes of shares of any Kemper Mutual Fund, and
(c) the value of any other plan investments, such as guaranteed investment
contracts and employer stock, maintained on such subaccount record keeping
system.
 
CLASS A SHARES -- LETTER OF INTENT. The same reduced sales charges for Class A
shares, as shown in the applicable prospectus, also apply to the aggregate
amount of purchases of such Kemper Mutual Funds listed above made by any
purchaser within a 24-month period under a written Letter of Intent ("Letter")
provided by KDI. The Letter, which imposes no obligation to purchase or sell
additional Class A shares, provides for a price adjustment depending upon the
actual amount purchased within such period. The Letter provides that the first
purchase following execution of the Letter must be at least 5% of the amount of
the intended purchase, and that 5% of the amount of the intended purchase
normally will be held in escrow in the form of shares pending completion of the
intended purchase. If the total investments under the Letter are less than the
intended amount and thereby qualify only for a higher sales charge than actually
paid, the appropriate number of escrowed shares are redeemed and the proceeds
used toward satisfaction of the obligation to pay the increased sales charge.
The Letter for an employer sponsored employee benefit plan maintained on the
subaccount record keeping system available through the Shareholder Service Agent
may have special provisions regarding payment of any increased sales charge
resulting from a failure to complete the intended purchase under the Letter. A
shareholder may include the value (at the maximum offering price) of all shares
of such Kemper Mutual Funds held of record as of the initial purchase date under
the Letter as an "accumulation credit" toward the completion of the Letter, but
no price adjustment will be made on such shares. Only investments in Class A
shares of a Fund are included for this privilege.
 
CLASS A SHARES -- CUMULATIVE DISCOUNT. Class A shares of a Fund may also be
purchased at the rate applicable to the discount bracket attained by adding to
the cost of shares of a Fund being purchased, the value of all Class A shares of
the above mentioned Kemper Mutual Funds (computed at the maximum offering price
at the time of the purchase for which the discount is applicable) already owned
by the investor.

<PAGE>   130
 
CLASS A SHARES -- AVAILABILITY OF QUANTITY DISCOUNTS. An investor or the
investor's dealer or other financial services firm must notify the Shareholder
Service Agent or KDI whenever a quantity discount or reduced sales charge is
applicable to a purchase. Upon such notification, the investor will receive the
lowest applicable sales charge. Quantity discounts described above may be
modified or terminated at any time.
 
EXCHANGE PRIVILEGE. Shareholders of Class A, Class B and Class C shares may
exchange their shares for shares of the corresponding class of other Kemper
Mutual Funds in accordance with the provisions below.
 
CLASS A SHARES. Class A shares of the Kemper Mutual Funds and shares of the
Money Market Funds listed under "Special Features--Class A Shares--Combined
Purchases" above may be exchanged for each other at their relative net asset
values. Shares of Money Market Funds and the Kemper Cash Reserves Fund that were
acquired by purchase (not including shares acquired by dividend reinvestment)
are subject to the applicable sales charge on exchange. Series of Kemper Target
Equity Fund are available on exchange only during the Offering Period for such
series as described in the applicable prospectus. Cash Equivalent Fund,
Tax-Exempt California Money Market Fund, Cash Account Trust, Investors Municipal
Cash Fund and Investors Cash Trust are available on exchange but only through a
financial services firm having a services agreement with KDI.
 
Class A shares of a Fund purchased under the Large Order NAV Purchase Privilege
may be exchanged for Class A shares of another Kemper Mutual Fund or a Money
Market Fund under the exchange privilege described above without paying any
contingent deferred sales charge at the time of exchange. If the Class A shares
received on exchange are redeemed thereafter, a contingent deferred sales charge
may be imposed in accordance with the foregoing requirements provided that the
shares redeemed will retain their original cost and purchase date for purposes
of the contingent deferred sales charge.
 
CLASS B SHARES. Class B shares of a Fund and Class B shares of any other Kemper
Mutual Fund listed under "Special Features --Class A Shares--Combined Purchases"
may be exchanged for each other at their relative net asset values. Class B
shares may be exchanged without any contingent deferred sales charge being
imposed at the time of exchange. For purposes of the contingent deferred sales
charge that may be imposed upon the redemption of the Class B shares received on
exchange, amounts exchanged retain their original cost and purchase date.
 
CLASS C SHARES. Class C shares of a Fund and Class C shares of any other Kemper
Mutual Fund listed under "Special Features--Class A Shares--Combined Purchases"
may be exchanged for each other at their relative net asset values. Class C
shares may be exchanged without a contingent deferred sales charge being imposed
at the time of exchange. For determining whether there is a contingent deferred
sales charge that may be imposed upon the redemption of the Class C shares
received by exchange, they retain the cost and purchase date of the shares that
were originally purchased and exchanged.
 
GENERAL. Shares of a Kemper Mutual Fund with a value in excess of $1,000,000
(except Kemper Cash Reserves Fund) acquired by exchange from another Kemper
Mutual Fund, or from a Money Market Fund, may not be exchanged thereafter until
they have been owned for 15 days (the "15 Day Hold Policy"). For purposes of
determining whether the 15 Day Hold Policy applies to a particular exchange, the
value of the shares to be exchanged shall be computed by aggregating the value
of shares being exchanged for all accounts under common control, direction, or
advice, including without limitation, accounts administered by a financial
services firm offering market timing, asset allocation or similar services. The
total value of shares being exchanged must at least equal the minimum investment
requirement of the Kemper Fund into which they are being exchanged. Exchanges
are made based on relative dollar values of the shares involved in the exchange.
There is no service fee for an exchange; however, dealers or other firms may
charge for their services in effecting exchange transactions. Exchanges will be
effected by redemption of shares of the fund held and purchase of shares of the
other fund. For federal income tax purposes, any such exchange constitutes a
sale upon which a gain or loss may be realized, depending upon whether the value
of the shares being exchanged is more or less than the shareholder's adjusted
cost basis of such shares. Shareholders interested in exercising the exchange
privilege may obtain prospectuses of the other funds from dealers, other firms
or KDI. Exchanges may be accomplished by a written request to KSvC, Attention:
Exchange Department, P.O. Box 419557, Kansas City, Missouri 64141-6557, or by
telephone if the
 
                                       50
<PAGE>   131
 
shareholder has given authorization. Once the authorization is on file, the
Shareholder Service Agent will honor requests by telephone at 1-800-621-1048,
subject to the limitations on liability under "Redemption or Repurchase of
Shares -- General." Any share certificates must be deposited prior to any
exchange of such shares. During periods when it is difficult to contact the
Shareholder Service Agent by telephone, it may be difficult to use the telephone
exchange privilege. The exchange privilege is not a right and may be suspended,
terminated or modified at any time. Except as otherwise permitted by applicable
regulations, 60 days' prior written notice of any termination or material change
will be provided. Exchanges may only be made for funds that are available for
sale in the shareholder's state of residence. Currently, Tax-Exempt California
Money Market Fund is available for sale only in California and the portfolios of
Investors Municipal Cash Fund are available for sale only in certain states.
 
SYSTEMATIC EXCHANGE PRIVILEGE. The owner of $1,000 or more of any class of the
shares of a Kemper Mutual Fund or Money Market Fund may authorize the automatic
exchange of a specified amount ($100 minimum) of such shares for shares of the
same class of another such Kemper Fund. If selected, exchanges will be made
automatically until the privilege is terminated by the shareholder or the other
Kemper Fund. Exchanges are subject to the terms and conditions described above
under "Exchange Privilege" except that the $1,000 minimum investment requirement
for the Kemper Fund acquired on exchange is not applicable. This privilege may
not be used for the exchange of shares held in certificated form.
 
EXPRESS-TRANSFER. EXPRESS-Transfer permits the transfer of money via the
Automated Clearing House System (minimum $100 and maximum $50,000) from a
shareholder's bank, savings and loan, or credit union account to purchase shares
in a Fund. Shareholders can also redeem shares (minimum $100 and maximum
$50,000) from their Fund account and transfer the proceeds to their bank,
savings and loan, or credit union checking account. Shares purchased by check or
through EXPRESS-Transfer or Bank Direct Deposit may not be redeemed under this
privilege until such shares have been owned for at least 10 days. By enrolling
in EXPRESS-Transfer, the shareholder authorizes the Shareholder Service Agent to
rely upon telephone instructions from ANY PERSON to transfer the specified
amounts between the shareholder's Fund account and the predesignated bank,
savings and loan or credit union account, subject to the limitations on
liability under "Redemption or Repurchase of Shares -- General." Once enrolled
in EXPRESS-Transfer, a shareholder can initiate a transaction by calling
Shareholder Services toll free at 1-800-621-1048 Monday through Friday, 8:00
a.m. to 3:00 p.m. Chicago time. Shareholders may terminate this privilege by
sending written notice to KSvC, P.O. Box 419415, Kansas City, Missouri
64141-6415. Termination will become effective as soon as the Shareholder Service
Agent has had a reasonable time to act upon the request. EXPRESS-Transfer cannot
be used with passbook savings accounts or for tax-deferred plans such as
Individual Retirement Accounts ("IRAs").
 
BANK DIRECT DEPOSIT. A shareholder may purchase additional shares of a Fund
through an automatic investment program. With the Bank Direct Deposit Purchase
Plan, investments are made automatically (minimum $50 maximum $50,000) from the
shareholder's account at a bank, savings and loan or credit union into the
shareholder's Fund account. By enrolling in Bank Direct Deposit, the shareholder
authorizes the Fund and its agents to either draw checks or initiate Automated
Clearing House debits against the designated account at a bank or other
financial institution. This privilege may be selected by completing the
appropriate section on the Account Application or by contacting the Shareholder
Service Agent for appropriate forms. A shareholder may terminate his or her Plan
by sending written notice to KSvC, P.O. Box 419415, Kansas City, Missouri
64141-6415. Termination by a shareholder will become effective within thirty
days after the Shareholder Service Agent has received the request. A Fund may
immediately terminate a shareholder's Plan in the event that any item is unpaid
by the shareholder's financial institution. The Funds may terminate or modify
this privilege at any time.
 
PAYROLL DIRECT DEPOSIT AND GOVERNMENT DIRECT DEPOSIT. A shareholder may invest
in a Fund through Payroll Direct Deposit or Government Direct Deposit. Under
these programs, all or a portion of a shareholder's net pay or government check
is automatically invested in a Fund account each payment period. A shareholder
may terminate participation in these programs by giving written notice to the
shareholder's employer or government agency, as appropriate. (A reasonable time
to act is required.) A Fund is not responsible for the efficiency of the
employer or government agency making the payment or any financial institutions
transmitting payments.
 
                                       51
<PAGE>   132
 
SYSTEMATIC WITHDRAWAL PLAN. The owner of $5,000 or more of a class of a Fund's
shares at the offering price (net asset value plus, in the case of Class A
shares, the initial sales charge) may provide for the payment from the owner's
account of any requested dollar amount up to $50,000 to be paid to the owner or
a designated payee monthly, quarterly, semiannually or annually. The $5,000
minimum account size is not applicable to Individual Retirement Accounts. The
minimum periodic payment is $100. The maximum annual rate at which Class B
shares may be redeemed (and Class A shares purchased under the Large Order NAV
Purchase Privilege and Class C shares in their first year following the
purchase) under a systematic withdrawal plan is 10% of the net asset value of
the account. Shares are redeemed so that the payee will receive payment
approximately the first of the month. Any income and capital gain dividends will
be automatically reinvested at net asset value. A sufficient number of full and
fractional shares will be redeemed to make the designated payment. Depending
upon the size of the payments requested and fluctuations in the net asset value
of the shares redeemed, redemptions for the purpose of making such payments may
reduce or even exhaust the account.
 
The purchase of Class A shares while participating in a systematic withdrawal
plan will ordinarily be disadvantageous to the investor because the investor
will be paying a sales charge on the purchase of shares at the same time that
the investor is redeeming shares upon which a sales charge may have already been
paid. Therefore, a Fund will not knowingly permit additional investments of less
than $2,000 if the investor is at the same time making systematic withdrawals.
KDI will waive the contingent deferred sales charge on redemptions of Class A
shares purchased under the Large Order NAV Purchase Privilege, Class B shares
and Class C shares made pursuant to a systematic withdrawal plan. The right is
reserved to amend the systematic withdrawal plan on 30 days' notice. The plan
may be terminated at any time by the investor or the Funds.
 
TAX-SHELTERED RETIREMENT PLANS. The Shareholder Service Agent provides
retirement plan services and documents and KDI can establish investor accounts
in any of the following types of retirement plans:
 
- - Individual Retirement Accounts ("IRAs") with IFTC as custodian. This includes
  Savings Incentive Match Plan for Employees of Small Employers ("SIMPLE"), IRA
  accounts and Simplified Employee Pension Plan ("SEP") IRA accounts and
  prototype documents.
 
- - 403(b)(7) Custodial Accounts also with IFTC as custodian. This type of plan is
  available to employees of most non-profit organizations.
 
- - Prototype money purchase pension and profit-sharing plans may be adopted by
  employers. The maximum annual contribution per participant is the lesser of
  25% of compensation or $30,000.
 
Brochures describing the above plans as well as model defined benefit plans,
target benefit plans, 457 plans, 401(k) plans, SIMPLE 401(k) plans and materials
for establishing them are available from the Shareholder Service Agent upon
request. The brochures for plans with IFTC as custodian describe the current
fees payable to IFTC for its services as custodian. Investors should consult
with their own tax advisers before establishing a retirement plan.
 
PERFORMANCE
 
A Fund may advertise several types of performance information for a class of
shares, including "yield" and "average annual total return" and "total return."
Performance information will be computed separately for Class A, Class B and
Class C shares. Each of these figures is based upon historical results and is
not representative of the future performance of any class of a Fund. A Fund with
fees or expenses being waived or absorbed by ZKI may also advertise performance
information before and after the effect of the fee waiver or expense absorption.
 
A Fund's yield is a measure of the net investment income per share earned over a
specific one month or 30-day period expressed as a percentage of the maximum
offering price of the Fund's shares at the end of the period. Yield is an
annualized figure, which means that it is assumed that a Fund generates the same
level of net
 
                                       52
<PAGE>   133
 
investment income over a one year period. Net investment income is assumed to be
compounded semiannually when it is annualized.
 
Average annual total return and total return figures measure both the net
investment income generated by, and the effect of any realized and unrealized
appreciation or depreciation of, the underlying investments in a Fund's
portfolio for the period referenced, assuming the reinvestment of all dividends.
Thus, these figures reflect the change in the value of an investment in a Fund
during a specified period. Average annual total return will be quoted for at
least the one, five and ten year periods ending on a recent calendar quarter (or
if such periods have not yet elapsed, at the end of a shorter period
corresponding to the life of the Fund for performance purposes). Average annual
total return figures represent the average annual percentage change over the
period in question. Total return figures represent the aggregate percentage or
dollar value change over the period in question.
 
A Fund's performance may be compared to that of the Consumer Price Index or
various unmanaged bond indexes including, but not limited to, the Salomon
Brothers High Grade Corporate Bond Index, the Lehman Brothers Adjustable Rate
Index, the Lehman Brothers Aggregate Bond Index, the Lehman Brothers Government/
Corporate Bond Index, the Salomon Brothers Long-Term High Yield Index, the
Salomon Brothers 30 Year GNMA Index and the Merrill Lynch Market Weighted Index
and may also be compared to the performance of other mutual funds or mutual fund
indexes with similar objectives and policies as reported by independent mutual
fund reporting services such as Lipper Analytical Services, Inc. ("Lipper").
Lipper performance calculations are based upon changes in net asset value with
all dividends reinvested and do not include the effect of any sales charges.
 
Information may be quoted from publications such as MORNINGSTAR, INC., THE WALL
STREET JOURNAL, MONEY MAGAZINE, FORBES, BARRON'S, FORTUNE, THE CHICAGO TRIBUNE,
USA TODAY, INSTITUTIONAL INVESTOR and REGISTERED REPRESENTATIVE. Also, investors
may want to compare the historical returns of various investments, performance
indexes of those investments or economic indicators, including but not limited
to stocks, bonds, certificates of deposit and other bank products, money market
funds and U.S. Treasury obligations. Bank product performance may be based upon,
among other things, the BANK RATE MONITOR National Index(TM) or various
certificate of deposit indexes. Money market fund performance may be based upon,
among other things, the IBC/Donoghue's Money Fund Report(R) or Money Market
Insight(R), reporting services on money market funds. Performance of U.S.
Treasury obligations may be based upon, among other things, various U.S.
Treasury bill indexes. Certain of these alternative investments may offer fixed
rates of return and guaranteed principal and may be insured. Economic indicators
may include, without limitation, indicators of market rate trends and cost of
funds, such as Federal Home Loan Bank Board 11th District Cost of Funds Index
("COFI").
 
A Fund may depict the historical performance of the securities in which the Fund
may invest over periods reflecting a variety of market or economic conditions
either alone or in comparison with alternative investments, performance indexes
of those investments or economic indicators. A Fund may also describe its
portfolio holdings and depict its size or relative size compared to other mutual
funds, the number and make-up of its shareholder base and other descriptive
factors concerning the Fund.
 
The yield or price volatility of a Fund (particularly the Adjustable Rate Fund)
may be compared to various securities, such as U.S. Government Securities, or
indexes, such as the COFI referred to above or the Constant Maturity Treasury
Index ("CMT") published by the Federal Reserve Board. A Fund may include in its
sales literature and shareholder reports a quotation of the current
"distribution rate" for the Fund. Distribution rate is simply a measure of the
level of dividends distributed for a specified period. It differs from yield,
which is a measure of the income actually earned by the Fund's investments, and
from total return, which is a measure of the income actually earned by, plus the
effect of any realized and unrealized appreciation or depreciation of, such
investments during the period. Distribution rate is, therefore, not intended to
be a complete measure of performance. Distribution rate may sometimes be greater
than yield since, for instance, it may include gains from the sale of options or
other short-term and possibly long-term gains (which may be non-recurring) and
may not
 
                                       53
<PAGE>   134
 
include the effect of amortization of bond premiums. As reflected under
"Investment Objectives, Policies and Risk Factors--Additional Investment
Information," option writing can limit the potential for capital appreciation.
 
Class A shares of each Fund are sold at net asset value plus a maximum sales
charge of 4.5% of the offering price (3.5% for the Adjustable Rate and
Short-Intermediate Government Funds). While the maximum sales charge is normally
reflected in a Fund's Class A performance figures, certain total return
calculations may not include such charge and those results would be reduced if
it were included. Class B shares and Class C shares are sold at net asset value.
Redemptions of Class B shares within the first six years after purchase may be
subject to a contingent deferred sales charge that ranges from 4% during the
first year to 0% after six years. Redemption of Class C shares within the first
year after purchase may be subject to a 1% contingent deferred sales charge.
Average annual total return figures do, and total return figures may, include
the effect of the contingent deferred sales charge for the Class B shares and
Class C shares that may be imposed at the end of the period in question.
Performance figures for the Class B shares and Class C shares not including the
effect of the applicable contingent deferred sales charge would be reduced if it
were included.
 
Each Fund's returns and net asset value will fluctuate and shares of a Fund are
redeemable by an investor at the then current net asset value, which may be more
or less than original cost. Redemption of Class B shares and Class C shares may
be subject to a contingent deferred sales charge as described above. Additional
information concerning each Fund's performance appears in the Statement of
Additional Information. Additional information about each Fund's performance
also appears in its Annual Report to Shareholders, which is available without
charge from the applicable Fund.
 
CAPITAL STRUCTURE
 
The Adjustable Rate, Diversified, Government, Income and Capital Funds, and High
Yield Series are open-end management investment companies, organized as separate
business trusts under the laws of Massachusetts. The Adjustable Rate Fund was
organized as a business trust under the laws of Massachusetts on May 28, 1987.
Prior to January 1, 1992, the Fund was known as "Kemper Enhanced Government
Income Fund." The Diversified Fund was organized as a business trust under the
laws of Massachusetts on October 24, 1985. Effective January 31, 1986, that Fund
pursuant to a reorganization succeeded to the assets and liabilities of Kemper
Option Income Fund, Inc., a Maryland corporation organized in 1977. Prior to
February 1, 1989, the Fund was known as "Kemper Option Income Fund." The
Government Fund was organized as a business trust under the laws of
Massachusetts on October 24, 1985. Effective January 31, 1986, that Fund
pursuant to a reorganization succeeded to the assets and liabilities of Kemper
U.S. Government Securities Fund, Inc., a Maryland corporation (formerly known as
Kemper Fund For Government Guaranteed Securities, Inc.) organized in 1980 as
successor to a Pennsylvania business trust organized in 1977. The High Yield and
Opportunity Funds are separate series, or "Portfolios," of Kemper High Yield
Series. The High Yield Series was organized as a business trust under the laws
of Massachusetts on October 24, 1985 with a single portfolio. Effective January
31, 1986, that Trust, pursuant to a reorganization succeeded to the assets and
liabilities of Kemper High Yield Fund, Inc., a Maryland corporation organized in
1977. Prior to October 1, 1997, the Trust was known as Kemper High Yield Fund.
The Income and Capital Fund was organized as a business trust under the laws of
Massachusetts on October 24, 1985. Effective January 31, 1986, that Fund
pursuant to a reorganization succeeded to the assets and liabilities of Kemper
Income and Capital Preservation Fund, Inc., a Maryland corporation organized in
1972. The Mortgage and Short-Intermediate Government Funds are separate series,
or "Portfolios", of Kemper Portfolios ("KP"), an open-end management investment
company organized as a business trust under the laws of Massachusetts on August
9, 1985. Effective November 20, 1987, KP pursuant to a reorganization succeeded
to the assets and liabilities of Investment Portfolios, Inc., a Maryland
corporation organized on March 26, 1982. After such reorganization, KP was known
as Investment Portfolios until February 1, 1991, and thereafter until May 28,
1994, as Kemper Investment Portfolios, when the name of KP became "Kemper
Portfolios." Until December 1, 1989, the Mortgage Fund was known as the
"Government Plus Portfolio" and prior to May 28, 1994, the Mortgage
 
                                       54
<PAGE>   135
 
Fund was known as the "Government Portfolio." Prior to May 28, 1994, the
Short-Intermediate Government Fund was known as the Short-Intermediate
Government Portfolio.
 
Each Trust may issue an unlimited number of shares of beneficial interest in one
or more series or "Portfolios," all having no par value, which may be divided by
the Board of Trustees into classes of shares. The Board of Trustees of each
Trust may authorize the issuance of additional classes and additional Portfolios
if deemed desirable, each with its own investment objective, policies and
restrictions. Since the Trusts may offer multiple Portfolios, each is known as a
"series company." Shares of a Portfolio have equal noncumulative voting rights
and equal rights with respect to dividends, assets and liquidation of such
Portfolio and are subject to any preferences, rights or privileges of any
classes of shares of the Portfolio. Currently, each Portfolio offers four
classes of shares. These are Class A, Class B and Class C shares, as well as
Class I shares, which have different expenses, that may affect performance, and
are available for purchase exclusively by the following investors: (a)
tax-exempt retirement plans of ZKI and its affiliates; and (b) the following
investment advisory clients of ZKI and its investment advisory affiliates that
invest at least $1 million in a Portfolio: (1) unaffiliated benefit plans, such
as qualified retirement plans (other than individual retirement accounts and
self-directed retirement plans); (2) unaffiliated banks and insurance companies
purchasing for their own accounts; and (3) endowment funds of unaffiliated
non-profit organizations. Shares of each Portfolio have equal noncumulative
voting rights except that Class B and Class C shares have separate and exclusive
voting rights with respect to each Portfolio's Rule 12b-1 Plan. Shares of each
class also have equal rights with respect to dividends, assets and liquidation
subject to any preferences (such as resulting from different Rule 12b-1
distribution fees), rights or privileges of any classes of shares of a
Portfolio. Shares of each Portfolio are fully paid and nonassessable when
issued, are transferable without restriction and have no preemptive or
conversion rights. The Trusts are not required to hold annual shareholder
meetings and do not intend to do so. However, they will hold special meetings as
required or deemed desirable for such purposes as electing trustees, changing
fundamental policies or approving an investment management agreement. Subject to
the Agreement and Declaration of Trust of each Trust, shareholders may remove
trustees. If shares of more than one Portfolio for any Trust are outstanding,
shareholders will vote by Portfolio and not in the aggregate or by class except
when voting in the aggregate is required under the 1940 Act, such as for the
election of trustees, or when voting by class is appropriate.

APPENDIX--PORTFOLIO COMPOSITION OF HIGH YIELD BONDS
 
The table below reflects the composition by quality rating of the portfolios of
the Diversified, High Yield and Opportunity Funds. Percentages for each Fund
reflect the net asset weighted average of the percentage for each category on
the last day of each month in the twelve month period ended October 31, 1997
(the one-month period for the Opportunity Fund). The table reflects the
percentage of total net assets represented by fixed income securities rated by
Moody's Investors Service, Inc. ("Moody's") or Standard & Poor's Corporation
("S&P"), by unrated fixed income securities and by other assets. The percentage
shown reflects the higher of the Moody's or S&P rating. U.S. Government
securities, whether or not rated, are reflected as Aaa and AAA (highest
quality). Cash equivalents include money market instruments, repurchase
agreements, net payables and receivables, treasuries with a maturity of less
than one year and cash. Other assets include options, financial futures
contracts and equity securities. As noted under "Investment Objectives, Policies
and Risk Factors" the Diversified, High Yield and Opportunity Funds invest in
high yielding, fixed income securities without relying upon published ratings.
The allocations in the table are not necessarily representative of the
composition of the portfolios at other times. Portfolio composition will change
over time.

The description of each bond quality category set forth in the table above is
intended to be a general guide and not a definitive statement as to how Moody's
and S&P define such rating category. A more complete description of the rating
categories is set forth under "Appendix--Ratings of Investments" in the
Statement of Additional Information. The ratings of Moody's and S&P represent
their opinions as to the quality of the securities that they undertake to rate.
It should be emphasized, however, that ratings are relative and subjective and
are not absolute standards of quality.

                      AGREEMENT AND PLAN OF REORGANIZATION
 
This Agreement and Plan of Reorganization (the "Agreement") is made as of
September 18, 1998, by and between the Kemper Adjustable Rate U.S. Government
Fund (the "Acquiring Fund") an open-end management investment company organized
as a business trust formed under the laws of the Commonwealth of Massachusetts,

                                  WITNESSETH:
 
WHEREAS, the Board of Trustees of the Acquiring Fund and the Acquired Fund
Trust, on behalf of the Acquired Fund, have determined that entering into this
Agreement for the Acquiring Fund to acquire the assets and liabilities of the
Acquired Fund is in the best interests of the shareholders of each respective
fund; and
 
WHEREAS, the parties intend that this transaction qualify as a reorganization
within the meaning of Section 368(a)(1) of the Internal Revenue Code of 1986, as
amended (the "Code");
 
NOW, THEREFORE, in consideration of the mutual promises contained herein, and
intending to be legally bound hereby, the parties hereto agree as follows:
 
1. PLAN OF TRANSACTION.
 
     a. TRANSFER OF ASSETS. Upon satisfaction of the conditions precedent set
     forth in Sections 7 and 8 hereof, the Acquired Fund will convey, transfer
     and deliver to the Acquiring Fund at the closing, provided for in Section 2
     hereof, all of the existing assets of the Acquired Fund (including accrued
     interest to the Closing Date), free and clear of all liens, encumbrances
     and claims whatsoever (the assets so transferred collectively being
     referred to as the "Assets").
 
     b. CONSIDERATION. In consideration thereof, the Acquiring Fund agrees that
     on the Closing Date, defined in Section 2 hereof, the Acquiring Fund will
     (i) deliver to the Acquired Fund, full and fractional Class A, Class B,
     Class C shares of beneficial interest of the Acquiring Fund having net
     asset values per share in an amount equal to the aggregate dollar value of
     the Assets net of any liabilities of the Acquired Fund described in Section
     3E hereof (the "Liabilities") determined pursuant to Section 3A of this
     Agreement (collectively, the "Acquiring Fund Shares") and (ii) assume all
     of the Acquired Fund's Liabilities. The calculation of full and fractional
     Class A, Class B and Class C shares of beneficial interest of the Acquiring
     Fund to be exchanged shall be carried out to no less than two (2) decimal
     places. On the Closing Date, the Acquiring Fund shall deliver to the
     Acquired Fund the Acquiring Fund Shares in the amount determined pursuant
     to this Section 1B and the Acquired Fund thereafter shall, in order to
     effect the distribution of such shares to the Acquired Fund's shareholders
     in liquidation of the Acquired Fund and in exchange for the shareholders'
     shares of the Acquired Fund, instruct the Acquiring Fund to register the
     pro rata interest in the Acquiring Fund Shares (in full and fractional
     shares) of each of the holders of record of shares of the Acquired Fund in
     accordance with their holdings of other Class A, Class B or Class C shares
     and shall provide as part of such instruction a complete and updated list
     of such holders (including addresses and taxpayer identification numbers),
     and the Acquiring Fund agrees promptly to comply with said instruction. The
     Acquiring Fund shall have no obligation to inquire as to the validity,
     propriety or correctness of such instruction, but shall assume that such
     instruction is valid, proper and correct. All Acquiring Fund Shares
     delivered to the Acquired Fund in exchange for such Assets shall be
     delivered at net asset value without sales load, commission or other
     similar fee being imposed.

CLOSING DATE. The closing shall be [                     ] or such later date as
the parties may mutually agree (the "Closing Date").
 
3. PROCEDURE FOR REORGANIZATION.
 
     a. VALUATION. The value of the Assets and Liabilities of the Acquired Fund
     to be transferred and assumed, respectively, by the Acquiring Fund shall be
     computed as of the Closing Date, in the manner set forth in the most recent
     Prospectus and Statement of Additional Information of the Acquiring Fund
     (collectively, the "Acquiring Fund Prospectus"), copies of which have been
     delivered to the Acquired Fund.
 
     b. DELIVERY OF FUND ASSETS. The Assets shall be delivered to [INVESTORS
     FIDUCIARY TRUST COMPANY, 801 PENNSYLVANIA AVENUE, KANSAS CITY, MISSOURI
     64105], as custodian for the Acquiring Fund (the "Custodian") for the
     benefit of the Acquiring Fund, duly endorsed in proper form for transfer in
     such condition as to constitute a good delivery thereof, free and clear of
     all liens, encumbrances and claims whatsoever, in accordance with the
     custom of brokers, and shall be accompanied by all necessary state stock
     transfer stamps.
 
     c. FAILURE TO DELIVER SECURITIES. If the Acquired Fund is unable to make
     delivery pursuant to Section 3B hereof to the Custodian of any of the
     Acquired Fund's securities for the reason that any of such securities
     purchased by the Acquired Fund have not yet been delivered to it by the
     Acquired Fund's broker or brokers, then, in lieu of such delivery, the
     Acquired Fund shall deliver to the Custodian, with respect to said
     securities, executed copies of an agreement of assignment and due bills
     executed on behalf of said broker or brokers, together with such other
     documents as may be required by the Acquiring Fund or Custodian, including
     brokers' confirmation slips.
 
     d. SHAREHOLDER ACCOUNTS. The Acquiring Fund, in order to assist the
     Acquired Fund in the distribution of the Acquiring Fund Shares to the
     Acquired Fund shareholders after delivery of the Acquiring Fund Shares to
     the Acquired Fund, will establish pursuant to the request of the Acquired
     Fund an open account with the Acquiring Fund for each shareholder of the
     Acquired Fund and, upon request by the Acquired Fund, shall transfer to
     such account the exact number of full and fractional Class A, Class B and
     Class C shares of the Acquiring Fund then held by the Acquired Fund
     specified in the instruction provided pursuant to Section 2 hereof. The
     Acquiring Fund is not required to issue certificates representing Acquiring
     Fund Shares. Upon liquidation or dissolution of the Acquired Fund,
     certificates representing shares of beneficial interest stock of the
     Acquired Fund shall become null and void.
 
     e. LIABILITIES. The Liabilities shall include all of Acquired Fund's
     liabilities, debts, obligations, and duties of whatever kind or nature,
     whether absolute, accrued, contingent, or otherwise, whether or not arising
     in the ordinary course of business, whether or not determinable at the
     Closing Date, and whether or not specifically referred to in this
     Agreement.
 
     f. EXPENSES. The expenses associated with the transactions contemplated
     herein will be borne by Scudder Kemper Investments, Inc., investment
     manager for the Funds.
 
     g. LIQUIDATION AND DISSOLUTION. As soon as practicable after the Closing
     Date but in no event later than one year after the Closing Date, the Board
     of Trustees of the Acquired Fund Trust and the Acquired Fund shall take all
     necessary and proper action to completely liquidate and terminate the
     Acquired Fund as a series in accordance with Massachusetts law and the
     Acquiring Fund Trust's Declaration of Trust. Immediately after the Closing
     Date, the stock transfer books relating to the Acquired Fund shall be
     closed and no transfer of shares shall thereafter be made on such books.

     being conducted, except authorizations which the failure to so obtain would
     not have a material adverse effect on the Acquired Fund.
 
     b. REGISTRATION. The Acquired Fund Trust is registered under the Investment
     Company Act of 1940, as amended (the "1940 Act") as an open-end management
     company and such registration has not been revoked or rescinded. The

     Acquired Fund Trust and the Acquired Fund are in compliance in all material
     respects with the 1940 Act and the rules and regulations thereunder. All of

     and not subject to pre-emptive or dissenters' rights.
 
     c. AUDITED FINANCIAL STATEMENTS. The statement of assets and liabilities
     and the portfolio of investments and the related statements of operations
     and changes in net assets of the Acquired Fund audited as of and for the
     fiscal year ended September 30, 1997, true and complete copies of which
     have been heretofore furnished to the Acquiring Fund, fairly represent the
     financial condition and the results of operations of the Acquired Fund as
     of and for their respective dates and periods in conformity with generally
     accepted accounting principles applied on a consistent basis during the
     periods involved.
 
     d. FINANCIAL STATEMENTS. The Acquired Fund shall furnish to the Acquiring

     1998; and (ii)] within five (5) business days after the Closing Date, an
     unaudited statement of assets and liabilities as of and for the interim
     period ending on the Closing Date; such financial statements will represent
     fairly the financial position and portfolio of investments and the results
     of the Acquired Fund's operations as of, and for the period ending on, the
     dates of such statements in conformity with generally accepted accounting
     principles applied on a consistent basis during the periods involved and
     the results of its operations and changes in financial position for the
     periods then ended; and such financial statements shall be certified by the
     Treasurer of the Acquired Fund as complying with the requirements hereof.
 
     e. CONTINGENT LIABILITIES. There are no contingent Liabilities of the
     Acquired Fund not disclosed in the financial statements delivered pursuant
     to Sections 4C and 4D which would materially affect the Acquired Fund's
     financial condition, and there are no legal, administrative, or other
     proceedings pending or, to its knowledge, threatened against the Acquired
     Fund which would, if adversely determined, materially affect the Acquired
     Fund's financial condition. All Liabilities were incurred by the Acquired
     Fund in the ordinary course of its business.
 
     f. MATERIAL AGREEMENTS. The Acquired Fund is in compliance with all
     material agreements, rules, laws, statutes, regulations and administrative
     orders affecting its operations or its assets; and except as referred to in

     Fund and Acquiring Fund from the date of the Agreement up to and including

     portfolio, the resulting portfolio will meet the Acquiring Fund's
     investment objective, policies and restrictions, as set forth in the
     Acquiring Fund's Prospectus, a copy of which has been delivered to the
     Acquired Fund.
 
     g. DISTRIBUTION OF THE SHARES. On the Closing Date, the Acquired Fund
     covenants that it shall cause to be distributed the Acquiring Fund Shares
     in the proper pro rata amount for the benefit of Acquired Fund's
     shareholders and such that the Acquired Fund shall not continue to hold

     the 1940 Act. The Acquired Fund covenants further that, pursuant to Section
     3G, it shall liquidate and dissolve as promptly as practicable after the
     Closing Date. The Acquired Fund covenants to use all reasonable efforts to

     in the distribution of said shares.
 
     h. BROKERS OR FINDERS. Except as disclosed in writing to the other party
     prior to the date hereof, each of the Acquired Fund and the Acquiring Fund

     other firm or person is or will be entitled to any broker's or finder's fee
     or any other commission or similar fee in connection with any of the

     other harmless from and against any all claims, liabilities or obligations
     with respect to any such fees, commissions or expenses asserted by any
     person to be due or payable in connection with any of the transactions
     contemplated by this Agreement on the basis of any act or statement alleged

     k. TAX STATUS OF REORGANIZATION. The intention of the parties is that the
     transaction will qualify as a reorganization within the meaning of Section
     368(a) of the Code. Neither the Acquired Fund Trust, the Acquiring Fund nor
     the Acquired Fund shall take any action, or cause any action to be taken
     (including, without limitation, the filing of any tax return) that is
     inconsistent with such treatment or results in the failure of the
     transaction to qualify as a reorganization within meaning of Section 368(a)
     of the Code. At or prior to the Closing Date, the Acquired Fund Trust, the
     Acquiring Fund and the Acquired Fund will take such action, or cause such
     action to be taken, as is reasonably necessary to enable Vedder, Price,
     Kaufman & Kammholz, counsel to both Funds, to render the tax opinion
     contemplated herein.
 
     l. DECLARATION OF DIVIDEND. At or immediately prior to the Closing Date,
     the Acquired Fund may declare and pay to its stockholders a dividend or
     other distribution in an amount large enough so that it will have

     investment

     taxable year through the Closing Date.

     material respects as of the Closing Date, and as of the Closing Date there
     shall have been no material adverse change in the financial condition,
     results of operations, business properties or assets of the Acquiring Fund,
     and the Acquired Fund shall have received a certificate of an authorized

     Acquired Fund so stating. The Acquiring Fund shall have performed and

     by this Agreement shall be in effect, nor shall any proceeding by any
     state, local or federal government agency or entity asking any of the
     foregoing be pending. There shall not be any action taken or any statute,
     rule, regulation or order enacted, entered, enforced or deemed applicable
     to the transactions contemplated by this Agreement, which makes the

     which has a material adverse effect on business operations of the Acquiring
     Fund.
 
     g. TAX OPINION. The Acquired Fund shall have obtained an opinion from
     Vedder, Price, Kaufman & Kammholz, counsel for the Acquired Fund, dated as

     described in Section 368(a) of the Code, substantially in the form attached
     as Annex A.
 
     h. OPINION OF COUNSEL. The Acquired Fund shall have received the opinion of
     Vedder, Price, Kaufman & Kammholz, counsel for the Acquiring Fund, dated as
     of the Closing Date, addressed to the Acquired Fund substantially in the
     form and to the effect that (i) the Acquiring Fund is duly organized and
     existing under the laws of the Commonwealth of Massachusetts as a voluntary
     association with transferable shares of beneficial interest commonly
     referred to as a "Massachusetts business trust"; (ii) the Acquiring Fund is
     registered as an open-end management company under the 1940 Act, (iii) this
     Agreement and the reorganization provided for herein and the execution of
     this Agreement have been duly authorized and approved by all requisite
     action of the Acquiring Fund and this Agreement has been duly executed and
     delivered by the Acquiring Fund and (assuming the Agreement is a valid and
     binding obligation of the other parties thereto) is a valid and binding
     obligation of the Acquiring Fund, except as such enforceability may be
     limited by bankruptcy, insolvency,
 
                                       A-9
<PAGE>   149
 
     fraudulent transfer, reorganization, moratorium or similar law affecting
     creditors' rights generally, or by general principals of equity (regardless
     of whether enforcement is sought in a proceeding at equity at law); (iv)
     neither the execution or delivery by the Acquiring Fund of this Agreement
     nor the consummation by the Acquiring Fund of the transactions contemplated
     thereby contravene the Acquiring Fund's Declaration of Trust, or, to the
     best of their knowledge, violate any provision of any statute or any
     published regulation or any judgment or order disclosed to it by the
     Acquiring Fund as being applicable to the Acquiring Fund, (v) to the best
     of their knowledge based solely on the certificate of an appropriate
     officer of the Acquiring Fund attached hereto, there is no pending or
     threatened litigation which would have the effect of prohibiting any
     material business practice or the acquisition of any material property or
     the conduct of any material business of the Acquiring Fund or might have a
     material adverse effect on the value of any assets of the Acquiring Fund;
     (vi) the Acquiring Fund Shares have been duly authorized and upon issuance
     thereof in accordance with this Agreement will, subject to certain matters
     regarding the liability of a shareholder of a Massachusetts business trust,
     be validly issued, fully paid and nonassessable; (vii) except as to
     financial statements and schedules and other financial and statistical data
     included or incorporated by reference therein and subject to usual and
     customary qualifications with respect to Rule 10b-5 type opinions, as of
     the effective date of the Registration Statement filed pursuant to the
     Agreement, the portions thereof pertaining to the Acquiring Fund comply as
     to form in all material respects with the requirements of the Securities
     Act, the Securities Exchange Act and the 1940 Act and the rules and
     regulations of the SEC thereunder and no facts have come to counsel's
     attention which would cause them to believe that as of the effectiveness of
     the portions of the Registration Statement applicable to the Acquiring
     Fund, the Registration Statement contained any untrue statement of a
     material fact or omitted to state any material fact required to be stated
     therein or necessary to make the statements therein not misleading, and
     (viii) to the best of its knowledge and information and subject to the
     qualifications set forth below, the execution and delivery by the Acquiring
     Fund of the Agreement and the consummation of the transactions therein
     contemplated do not require, under the laws of the Commonwealth of
     Massachusetts, laws of the State of Illinois or the federal laws of the
     United States, the consent, approval, authorization, registration,
     qualification or order of, or filing with, any court or governmental agency
     or body (except such as have been obtained). Counsel need express no
     opinion, however, as to any such consent, approval, authorization,
     registration, qualification, order or filing (a) which may be required as a
     result of the involvement of parties to the Agreement in the transactions
     contemplated by the Agreement because of their legal or regulatory status
     or because of any other facts specifically pertaining to them; (b) the
     absence of which does not deprive the Acquired Fund of any material benefit
     under the Agreement; or (c) which can be readily obtained without
     significant delay or expense to the Acquired Fund, without loss to the
     Acquired Fund of any material benefit under the Agreement and without any
     material adverse effect on the Acquired Fund during the period such
     consent, approval, authorization, registration, qualification or order was
     obtained. The foregoing opinion relates only to consents, approvals,
     authorizations, registrations, qualifications, orders or filings under (a)
     laws which are specifically referred to in this opinion, (b) laws of the
     Commonwealth of Massachusetts, laws of the State of Illinois or the federal
     laws of the United States which, in counsel's experience, are normally
     applicable to transactions of th e type provided for in the Agreement and
     (c) court orders and judgments disclosed to counsel by the Acquiring Fund
     in connection with the opinion. In addition, although counsel need not
     specifically have considered the possible applicability to the Acquiring
     Fund of any other laws, orders or judgments, nothing has come to their
     attention in connection with their representation of the Acquiring Fund in
     this transaction that has caused them to conclude that any other consent,
     approval, authorization, registration, qualification, order or filing is
     required. In giving the opinions set forth above, counsel may state that it
     is relying on certificates of officers of the Acquiring Fund with regard to
     matters of fact and certain certificates and written statements of
     government officers with respect to the good standing of the Acquiring Fund
     and on the opinion of Ropes & Gray as to matters of Massachusetts law.

<PAGE>   150
 
     warranties set forth in Section 5 are true and correct on the Closing Date,
     together with certified copies of the resolutions adopted by the Board of

     in the business, results of operations, assets or financial condition or

     changes in the ordinary course of its business, which has had a material

8. CONDITIONS TO OBLIGATIONS OF ACQUIRING FUND.
 
The obligations of the Acquiring Fund hereunder with respect to the consummation
of the Reorganization are subject to the satisfaction, or written waiver by the
Acquiring Fund of the following conditions:
 
     a. ACQUIRED FUND SHAREHOLDER APPROVAL. This Agreement and the transactions
     contemplated herein shall have been approved by the affirmative vote of the
     holders of at least a majority of the outstanding shares of beneficial
     interest of the Acquired Fund.
 
     b. ACQUIRING FUND SHAREHOLDER APPROVAL. A new investment objective and
     policies shall have been approved by a majority of the outstanding voting
     securities of the Acquiring Fund.
 
     c. REPRESENTATIONS, WARRANTIES AND AGREEMENTS. Each of the representations
     and warranties of the Acquired Fund contained herein shall be true in all
     material respects as of the Closing Date, and as of the Closing Date there
     shall have been no material adverse change in the financial condition,
     results of operations, business, properties or assets of the Acquired Fund,
     and the Acquiring Fund shall have received a certificate of an authorized
     officer of the Acquired Fund satisfactory in form and substance to the
     Acquiring Fund so stating. The Acquired Fund shall have performed and
     complied in all material respects with all agreements, obligations and
     covenants required by this Agreement to be so performed or complied with by
     them on or prior to the Closing Date.
 
     d. REGISTRATION STATEMENT EFFECTIVE. The Registration Statement shall have

     consummation of the transactions contemplated by this Agreement shall be in
     effect, nor shall any proceeding by any state, local or federal government
     agency or entity seeking any of the foregoing be pending. There shall not
     be any action taken, or any statute, rule, regulation or order enacted,
     entered, enforced or deemed applicable to the transactions contemplated by
     this Agreement, which makes the consummation of the transactions
     contemplated by this Agreement illegal.
 
     g. TAX OPINION. The Acquiring Fund shall have obtained an opinion from
     Vedder, Price, Kaufman & Kammholz, counsel for the Acquired Fund, dated as
     of the Closing Date, addressed to the Acquiring Fund, Acquired Fund Trust,
     Acquired Fund and Acquiring Fund, that the consummation of the transactions
     set forth in this Agreement comply with the requirements of a
     reorganization as described in Section 368(a) of the Code substantially in
     the form attached as Annex A.
 
     h. OPINION OF COUNSEL. The Acquiring Fund shall have received the opinion
     of Vedder, Price, Kaufman & Kammholz, counsel for the Acquired Fund Trust
     and the Acquired Fund, dated as of the Closing Date, addressed to the
     Acquiring Fund, substantially in the form and to the effect that: (i) the
     Acquired Fund Trust is duly organized and existing under the laws of the
     Commonwealth of Massachusetts as a voluntary association with transferable
     shares of beneficial interest commonly referred to as a "Massachusetts
     business trust"; (ii) the Board of Trustees of the Acquired Fund Trust has
     duly designated the Acquired Fund as a series of the Acquired Fund Trust
     pursuant to the terms of the Declaration of Trust of the Acquired Fund
     Trust, (iii) the Acquired Fund Trust is registered as an open-end
     management company under the 1940 Act; (iv) this Agreement and the
     reorganization provided for herein and the execution of this Agreement have
     been duly authorized by all requisite
 
                                      A-11
<PAGE>   151
 
     action of the Acquired Fund Trust and this Agreement has been duly executed
     and delivered by the Acquired Fund Trust on behalf of the Acquired Fund and
     (assuming the Agreement is a valid and binding obligation of the other
     parties thereto) is a valid and binding obligation of the Acquired Fund,
     except as such enforceability may be limited by bankruptcy, insolvency,
     fraudulent transfer, reorganization, moratorium or similar law affecting
     creditors' rights generally, or by general principals of equity (regardless
     of whether enforcement is sought in a proceeding at equity or law); (v)
     neither the execution or delivery by the Acquired Fund Trust on behalf of
     the Acquired Fund of this Agreement nor the consummation by the Acquired
     Fund Trust or Acquired Fund of the transactions contemplated thereby
     contravene the Acquired Fund Trust's Declaration of Trust or, to their
     knowledge, violate any provision of any statute, or any published
     regulation or any judgment or order disclosed to them by the Acquired Fund
     Trust as being applicable to the Acquired Fund Trust or Acquired Fund; (vi)
     to the best of their knowledge based solely on the certificate of an
     appropriate officer of the Acquired Fund attached thereto, there is no
     pending, or threatened litigation involving the Acquired Fund except as
     disclosed therein; (vii) except as to financial statements and schedules
     and other financial and statistical data included or incorporated by
     reference therein and subject to usual and customary qualifications with
     respect to Rule 10b-5 type opinions, as of the effective date of the
     Registration Statement filed pursuant to the Agreement, the portions
     thereof pertaining to the Acquired Fund comply as to form in all material
     respects with their requirements of the Securities Act, the Securities
     Exchange Act and the 1940 Act and the rules and regulations of the SEC
     thereunder and no facts have come to counsel's attention which cause them
     to believe that as of the effectiveness of the portions of the Registration
     Statement applicable to the Acquired Fund, the Registration Statement
     contained any untrue statement of a material fact or omitted to state any
     material fact required to be stated therein or necessary to make the
     statements therein not misleading, and (viii) to their knowledge and
     subject to the qualifications set forth below, the execution and delivery
     by the Acquired Fund Trust on behalf of the Acquired Fund of the Agreement
     and the consummation of the transactions therein contemplated do not
     require, under the laws of the Commonwealth of Massachusetts, laws of the
     State of Illinois or the federal laws of the United States, the consent,
     approval, authorization, registration, qualification or order of, or filing
     with, any court or governmental agency or body (except such as have been
     obtained), except for the filing of an amendment to the Acquired Fund
     Trust's Designation of Series in connection with the termination of the
     Acquired Fund. Counsel need express no opinion, however, as to any such
     consent, approval, authorization, registration, qualification, order or
     filing (a) which may be required as a result of the involvement of other
     parties to the Agreement in the transactions contemplated by the Agreement
     because of their legal or regulatory status or because of any other facts
     specifically pertaining to them; (b) the absence of which does not deprive
     the Acquiring Fund of any material benefit under such agreements; or (c)
     which can be readily obtained without significant delay or expense to the
     Acquiring Fund, without loss to the Acquiring Fund of any material benefit
     under the Agreement and without any material adverse effect on them during
     the period such consent, approval authorization, registration,
     qualification or order was obtained. The foregoing opinion relates only to
     consents, approvals, authorizations, registrations, qualifications, orders
     or filings under (a) laws which are specifically referred to in the
     opinion, (b) laws of the Commonwealth of Massachusetts, laws of the State
     of Illinois or the federal laws of the United States which, in our
     experience, are normally applicable to transactions of the type provided
     for in the Agreement and (c) court orders and judgments disclosed to
     counsel by the Acquired Fund in connection with the opinion. In addition,
     although counsel need not specifically consider the possible applicability
     to the Acquired Fund of any other laws, orders or judgments, nothing has
     come to their attention in connection with their representation of the
     Acquired Fund in this transaction that has caused them to conclude that any
     other consent, approval, authorization, registration, qualification, order
     or filing is required. In giving the opinion set forth above, counsel may
     state that it is relying on certificates of officers of the Acquired Fund
     with regard to matters of fact and certain certificates and written
     statutes of government officers with respect to the good standing of the
     Acquired Fund and on the opinion of Ropes & Gray as to matters of
     Massachusetts law.

Gentlemen:
 
You have requested our opinion regarding certain federal income tax consequences
of the proposed reorganization ("Reorganization") of Kemper Short-Intermediate
Government Fund ("Acquired Fund"), a separate portfolio of Kemper Portfolios, an
open-end management investment company organized as a business trust under the
laws of the Commonwealth of Massachusetts ("Acquired Trust") into Kemper
Adjustable Rate U.S. Government Fund ("Acquiring Fund"), an open-end management
investment company organized as a business trust under the laws of the
Commonwealth of Massachusetts. The Reorganization contemplates the acquisition
by the Acquiring Fund of substantially all the assets of the Acquired Fund in
exchange for voting shares of beneficial interest ("shares") of the Acquiring
Fund and the assumption of the Acquired Fund's liabilities. Thereafter, the
shares of the Acquiring Fund will be distributed to the shareholders of the
Acquired Fund and the Acquired Fund will be completely liquidated and
terminated. The foregoing will be accomplished pursuant to an Agreement and Plan
of Reorganization, dated as of                (the "Plan"), entered into by the
Acquired Trust, on behalf of the Acquired Fund, and the Acquiring Fund.
 
In rendering this opinion, we have reviewed and relied upon statements made to
us by certain of your officers. We have also examined certificates of such
officers and such other agreements, documents, and corporate records that have
been made available to us and such other matters as we have deemed relevant for
purposes of this opinion. In such examination, we have assumed the genuineness
of all signatures, the authenticity of all documents submitted to us as
originals, the conformity to originals of all documents submitted to us as
copies and the authenticity of the originals of such latter documents.
 
Our opinion is based, in part, on the assumption that the proposed
Reorganization described herein will occur in accordance with the agreements and
the facts and representations set forth or referred to in this opinion letter,
and that such facts and representations are accurate as of the date hereof and
will be accurate on the effective date of the Reorganization (the "Effective
Time"). As more fully discussed below, we have also assumed in issuing our
opinion that the shareholders of the Acquired Fund do not have any plan or
intention to dispose of a certain number of the Acquiring Fund shares received
by them in the Reorganization. We have undertaken no independent investigation
of the accuracy of the facts, representations and assumptions set forth or
referred to herein.
 
For the purposes indicated above, and based upon the facts, assumptions and
conditions as set forth herein, and the representations made to us by duly
authorized officers on behalf of the Acquired Fund and the Acquiring Fund in a
letter dated                , 1998, it is our opinion that:
 
     (1) The acquisition by the Acquiring Fund of substantially all the assets
     of the Acquired Fund in exchange solely for Acquiring Fund voting shares
     and the assumption by the Acquiring Fund of the Acquired Fund's
     liabilities, if any, followed by the distribution by the Acquired Fund of
     the Acquiring Fund shares to the shareholders of the Acquired Fund in
     exchange for their Acquired Fund shares in complete liquidation of the
     Acquired Fund, will constitute a "reorganization" within the meaning of
     Section 368 (a)(1) C) of the Internal Revenue Code of 1986, as amended (the
     "Code"), and the Acquiring Fund and the Acquired Fund will each be "a party
     to a reorganization" within the meaning of Section 368(b) of the Code;
 
                                       A-1

     (2) The Acquired Fund shareholders will recognize no gain or loss upon the
     exchange of all of their Acquired Fund shares for Acquiring Fund shares in
     complete liquidation of the Acquired Fund (Code Section 354(a)(1));
 
     (3) No gain or loss will be recognized by the Acquired Fund upon the
     transfer of substantially all its assets to the Acquiring Fund in exchange
     solely for Acquiring Fund shares and the assumption by the Acquiring Fund
     of the Acquired Fund's liabilities, if any, and with respect to the
     subsequent distribution of those Acquiring Fund shares to the Acquired Fund
     shareholders in complete liquidation of the Acquired Fund (Code Section
     361);
 
     (4) No gain or loss will be recognized by the Acquiring Fund upon the
     acquisition of substantially all the Acquired Fund's assets in exchange
     solely for Acquiring Fund shares and the assumption of the Acquired Fund's
     liabilities, if any (Code Section 1032(a));
 
     (5) The basis of the assets acquired by the Acquiring Fund will be, in each
     instance, the same as the basis of those assets immediately before the
     transfer when such assets were held by the Acquired Fund, and the holding
     period of such assets acquired by the Acquiring Fund will include the
     holding period thereof when such assets were held by the Acquired Fund
     (Code Sections 362(b) and 1223(2));
 
     (6) The basis of the Acquiring Fund shares to be received by the Acquired
     Fund shareholders upon liquidation of the Acquired Fund will be, in each
     instance, the same as the basis of the Acquired Fund shares surrendered in
     exchange therefor (Code Section 358(a)(1)); and
 
     (7) The holding period of the Acquiring Fund shares to be received by the
     Acquired Fund shareholders will include the period during which the
     Acquired Fund shares to be surrendered in exchange therefor were held,
     provided such Acquired Fund shares were held as capital assets by those
     shareholders on the date of the exchange (Code Section 1223(1)).
 
                                     FACTS
 
Our opinion is based upon the above referenced representations and the following
facts and assumptions, any alteration of which could adversely affect our
conclusions.
 
The Acquired Fund has been registered and operated since it commenced operations
as a series of an open-end, management investment company under the Investment
Company Act of 1940, 15 U.S.C. Section 80a, et seq. (the "1940 Act"). The
Acquired Fund has qualified and will qualify as a regulated investment company
under Section 851 of the Code for each of its taxable years, and has distributed
and will distribute all or substantially all its income so that it and its
shareholders have been and will be taxed in accordance with Section 852 of the
Code.
 
The Acquiring Fund is registered, has operated, and will continue to operate an
open-end, management investment company under the 1940 Act. It has qualified as
a regulated investment company under Section 851 of the Code for each of its
taxable years and anticipates so qualifying for all future years, and has
distributed and will distribute all or substantially all its income so that it
and its shareholders will be taxed in accordance with Section 852 of the Code.
 
Upon satisfaction of certain terms and conditions set forth in the Plan on or
before the Effective Time, the following will occur: (a) the Acquiring Fund will
acquire substantially all the assets of the Acquired Fund in exchange for the
Acquiring Fund's assumption of substantially all the liabilities of the Acquired
Fund and the issuance of Acquiring Fund shares to the Acquired Fund; (b) the
Acquiring Fund shares will be distributed to the shareholders of the Acquired
Fund in exchange for their Acquired Fund shares; and

(c) the Acquired Fund will be dissolved and liquidated. The assets of the
Acquired Fund to be acquired by the Acquiring Fund consist primarily of short
and intermediate-term U.S. Government securities, cash and other securities held
in the Acquired Fund's portfolio.
 
As soon as practicable after the Effective Time, the Acquired Fund will be
liquidated and will distribute the newly issued Acquiring Fund shares it
receives pro rata to its shareholders of record in exchange for such
shareholders' interests in the Acquired Fund. The liquidation and distribution
will be accomplished by opening accounts on the books of the Acquiring Fund in
the names of the shareholders of the Acquired Fund (on a class by class basis)
and transferring to those shareholder accounts the pro rata number of Acquiring
Fund shares of each respective class as was previously credited to the Acquired
Fund on the books.
 
As a result of the Reorganization, every shareholder of the Acquired Fund will
own Acquiring Fund shares that would have an aggregate per share net asset value
immediately after the Effective Time equal to the aggregate per share net asset
value of that shareholder's Acquired Fund shares immediately prior to the
Effective Time. Since the Acquiring Fund shares issued to the shareholders of
the Acquired Fund will be issued at net asset value in exchange for the net
assets of the Acquired Fund having a value equal to the aggregate per share net
asset value of those Acquiring Fund shares so issued, the net asset value of the
Acquiring Fund shares should remain virtually unchanged by the Reorganization.
 
[THE INVESTMENT OBJECTIVES OF THE ACQUIRING FUND WILL BE SUBSTANTIALLY SIMILAR
TO THOSE OF THE ACQUIRED FUND AND THE ACQUIRING FUND WILL CONTINUE THE HISTORIC
BUSINESS OF THE ACQUIRED FUND OR USE A SIGNIFICANT PORTION OF THE ACQUIRED
FUND'S HISTORIC ASSETS IN ITS BUSINESS.]
 
The management of the Acquired Fund has represented to us that, to the best of
their knowledge, there is no current plan or intention on the part of any
Acquired Fund shareholders to sell, exchange, or otherwise dispose of a number
of Acquiring Fund shares received in the Reorganization that would reduce the
ownership by shareholders of the Acquired Fund to a number of shares of
Acquiring Fund having a value, as of the Effective Time, of less than 50 percent
of all the formerly outstanding shares of the Acquired Fund as of the same time.
In issuing our opinion, we have assumed that there is, in fact, no such plan or
intention. If such assumption were inaccurate, it could adversely affect the
opinions contained herein.
 
In approving the Reorganization, the Board of Trustees of the Acquired Trust
identified certain benefits that are likely to result from combining the funds,
including administrative and operating efficiencies, and greater portfolio
diversity. The Board also considered the possible risks and costs of combining
the funds and determined that the Reorganization is likely to provide benefits
to the shareholders of the fund that outweigh the costs incurred.
 
                                   CONCLUSION
 
Based on the foregoing, it is our opinion that the acquisition by the Acquiring
Fund, pursuant to the Plan, of substantially all the assets and liabilities of
the Acquired Fund in exchange for voting shares of the Acquiring Fund will
qualify as a reorganization under Code Section 368(a)(1)(C).
 
Our opinions set forth above with respect to (1) the nonrecognition of gain or
loss to the Acquired Fund and the Acquiring Fund, (2) the basis and holding
period of the assets received by the Acquiring Fund, (3) the nonrecognition of
gain or loss to the Acquired Fund shareholders upon the receipt of the Acquiring
Fund shares, and (4) the basis and holding period of the Acquiring Fund shares
received by the Acquired Fund shareholders, follow as a matter of law from the
opinion that the acquisition under the Plan will qualify as a reorganization
under Code Section 368(a)(1)(C).

The opinions expressed in this letter are based on the Code, the Income Tax
Regulations promulgated by the Treasury Department thereunder and judicial
authority reported as of the date hereof. We have also considered the position
of the Internal Revenue Service (the "Service") reflected in published and
private rulings. Although we are not aware of any pending changes to these
authorities that would alter our opinions, there can be no assurances that
future legislative or administrative changes, court decisions or Service
interpretations will not significantly modify the statements or opinions
expressed herein.
 
Our opinions are limited to those federal income tax issues specifically
considered herein and are addressed to and are only for the benefit of the
Acquired Fund, the Acquired Trust and the Acquiring Fund. We do not express any
opinion as to any other federal income tax issues, or any state or local law
issues, arising from the transactions contemplated by the Plan. Although the
discussion herein is based upon our best interpretation of existing sources of
law and expresses what we believe a court would properly conclude if presented
with these issues, no assurance can be given that such interpretations would be
followed if they were to become the subject of judicial or administrative
proceedings.
 
We hereby consent to the filing of this opinion as an Exhibit to the
Registration Statement and to the use of our name under the captions "Proposal
No. 1--The Proposed Reorganization--Certain federal Income Tax Consequences" and
"Legal Matters" in the Prospectus/Proxy Statement contained in such Registration
Statement. In giving such consent, we do not thereby concede that we are within
the category of persons whose consent is required under Section 7 of the
Securities Act of 1933, as amended, or the rules and regulations of the
Securities and Exchange Commission thereunder.

The following disclosure supplements information in each Fund's Statement of
Additional Information.
 
PURCHASE AND REDEMPTION OF SHARES
 
The Fund has authorized certain members of the National Association of
Securities Dealers, Inc. ("NASD"), other than Kemper Distributors, Inc. ("KDI"),
to accept purchase and redemption orders for the Fund's shares. Those brokers
may also designate other parties to accept purchase and redemption orders on the
Fund's behalf. Orders for purchase or redemption will be deemed to have been
received by the Fund when such brokers or their authorized designees accept the
orders. Subject to the terms of the contract between the Fund and the broker,
ordinarily orders will be priced at the Fund's net asset value next computed
after acceptance by such brokers or their authorized designees. Further, if
purchases or redemptions of the Fund's shares are arranged and settlement is
made at an investor's election through any other authorized NASD member, that
member may, at its discretion, charge a fee for that service. The Board of
Trustees or Directors as the case may be ("Board") of the Fund and KDI each has
the right to limit the amount of purchases by, and to refuse to sell to, any
person. The Board and KDI may suspend or terminate the offering of shares of the
Fund at any time for any reason.

INVESTMENT RESTRICTIONS
 
Each Fund has adopted certain fundamental investment restrictions which,
together with the investment objective and fundamental policies of such Fund,
cannot be changed without approval of a majority of its outstanding voting
shares. As defined in the Investment Company Act of 1940, this means the lesser
of the vote of (a) 67% of the shares of the Fund present at a meeting where more
than 50% of the outstanding shares are present in person or by proxy or (b) more
than 50% of the outstanding shares of the Fund.
 
THE ADJUSTABLE RATE FUND MAY NOT, AS A FUNDAMENTAL POLICY:
 
(1) Purchase securities of any issuer (other than obligations of, or guaranteed
by, the U.S. Government, its agencies or instrumentalities) if, as a result,
more than 5% of the total value of the Fund's assets would be invested in
securities of that issuer.
 
(2) Purchase more than 10% of any class of voting securities of any issuer.
 
(3) Make loans to others provided that the Fund may purchase debt obligations or
repurchase agreements and it may lend its securities in accordance with its
investment objective and policies.
 
(4) Borrow money except as a temporary measure for extraordinary or emergency
purposes, and then only in an amount up to one-third of the value of its total
assets, in order to meet redemption requests without immediately selling any
portfolio securities. If, for any reason, the current value of the Fund's total
assets falls below an amount equal to three times the amount of its indebtedness
from money borrowed, the Fund will, within three days (not including Sundays and
holidays), reduce its indebtedness to the extent necessary. The Fund will not
borrow for leverage purposes and will not purchase securities or make
investments while borrowings are outstanding.
 
(5) Pledge, hypothecate, mortgage or otherwise encumber more than 15% of its
total assets and then only to secure borrowings permitted by restriction 4
above. (The collateral arrangements with respect to options, financial futures
and delayed delivery transactions and any margin payments in connection
therewith are not deemed to be pledges or other encumbrances.)
 
(6) Purchase securities on margin, except to obtain such short-term credits as
may be necessary for the clearance of transactions; however, the Fund may make
margin deposits in connection with options and financial futures transactions.
 
(7) Make short sales of securities or maintain a short position for the account
of the Fund unless at all times when a short position is open it owns an equal
amount of such securities or owns securities which, without payment of any
further consideration, are convertible into or exchangeable for securities of
the same issue as, and equal in amount to, the securities sold short and unless
not more than 10% of the Fund's total assets is held as collateral for such
sales at any one time.
 
(8) Write or sell put or call options, combinations thereof or similar options
on more than 25% of the Fund's net assets; nor may the Fund purchase put or call
options if more than 5% of the Fund's net assets would be invested in premiums
on put and call options, combinations thereof or similar options; however, the
Fund may buy or sell options on financial futures contracts.
 
(9) Purchase securities (other than securities of the U.S. Government, its
agencies or instrumentalities including collateralized obligations thereof) if
as a result of such purchase 25% or more of the Fund's total assets would be
invested in any one industry.
 
(10) Invest in commodities or commodity futures contracts, although it may buy
or sell financial futures contracts and options on such contracts; or in real
estate, although it may invest in securities which are secured by real estate
and securities of issuers which invest or deal in real estate.
 
                                       B-2
<PAGE>   171
 
(11) Underwrite securities issued by others except to the extent the Fund may be
deemed to be an underwriter, under the federal securities laws, in connection
with the disposition of portfolio securities.
 
(12) Issue senior securities except as permitted under the Investment Company
Act of 1940.
 
If a percentage restriction is adhered to at the time of investment, a later
increase or decrease in percentage beyond the specified limit resulting from a
change in values or net assets will not be considered a violation. The Fund did
not borrow money as permitted by investment restriction number 4 in the latest
fiscal year and it has no present intention of borrowing during the current
year. The Fund has adopted the following non-fundamental restrictions, which may
be changed by the Board of Trustees without shareholder approval. The Adjustable
Rate Fund may not:
 
(i) Invest for the purpose of exercising control or management of another
issuer.
 
(ii) Invest more than 15% of its net assets in illiquid securities.
 
THE DIVERSIFIED FUND MAY NOT, AS A FUNDAMENTAL POLICY:
 
(1) With respect to 75% of the Fund's total assets, purchase securities of any
issuer (other than securities issued or guaranteed by the U.S. Government or any
of its agencies or instrumentalities) if, as a result, (a) more than 5% of the
Fund's total assets would be invested in securities of that issuer, or (b) the
Fund would hold more than 10% of the outstanding voting securities of that
issuer.
 
(2) Lend money or securities, provided that the making of time or demand
deposits with banks and the purchase of debt securities such as bonds,
debentures, commercial paper, repurchase agreements and short-term obligations
in accordance with its objective and policies are not prohibited and the Fund
may lend its portfolio securities as described in the prospectus.
 
(3) Borrow money except for temporary or emergency purposes (but not for the
purpose of purchase of investments) and then only in an amount not to exceed 5%
of the Fund's net assets; or pledge the Fund's securities or receivables or

INVESTMENT POLICIES AND TECHNIQUES
 
GENERAL. Each Fund may engage in options and financial futures and other
derivatives transactions in accordance with its respective investment objectives
and policies. Each such Fund intends to engage in such transactions if it
appears to the investment manager to be advantageous to do so in order to pursue
its investment objective and also to hedge against the effects of market risks
but not for speculative purposes. The use of futures and options, and possible
benefits and attendant risks, are discussed below along with information
concerning other investment policies and techniques.
 
OPTIONS ON SECURITIES. A Fund may write (sell) "covered" call options on
securities as long as it owns the underlying securities subject to the option or
an option to purchase the same underlying securities, having an exercise price
equal to or less than the exercise price of the "covered" option, or will
establish and maintain for the term of the option a segregated account
consisting of cash or other liquid securities ("eligible securities") to the
extent required by applicable regulation in connection with the optioned
securities. A Fund may write "covered" put options provided that, as long as the
Fund is obligated as a writer of a put option, the Fund will own an option to
sell the underlying securities subject to the option, having an exercise price
equal to or greater than the exercise price of the "covered" option, or it will
deposit and maintain in a segregated account eligible securities having a value
equal to or greater than the exercise price of the option. A call option gives
the purchaser the right to buy, and the writer the obligation to sell, the
underlying security at the exercise price during or at the end of the option
period. A put option gives the purchaser the right to sell, and the writer the
obligation to buy, the underlying security at the exercise price during or at
the end of the option period. The premium received for writing an option will
reflect, among other things, the current market price of the underlying
security, the relationship of the exercise price to such market price, the price
volatility of the underlying security, the option period, supply and demand and
interest rates. The Funds may write or purchase spread options, which are
options for which the exercise price may be a fixed dollar spread or yield
spread between the security underlying the option and another security that is
used as a bench mark. The exercise price of an option may be below, equal to or
above the current market value of the underlying security at the time the option
is written. The buyer of a put who also owns the related security is protected
by ownership of a put option against any decline in that security's price below
the exercise price less the amount paid for the option. The ability to purchase
put options allows a Fund to protect capital gains in an appreciated security it
owns, without being required to actually sell that security. At times a Fund
would like to establish a position in a security upon which call options are
available. By purchasing a call option, a Fund is able to fix the cost of
acquiring the security, this being the cost of the call plus the exercise price
of the option. This procedure also provides some protection from an unexpected
downturn in the market, because a Fund is only at risk for the amount of the
premium paid for the call option which it can, if it chooses, permit to expire.
 
During the option period the covered call writer gives up the potential for
capital appreciation above the exercise price should the underlying security
rise in value, and the secured put writer retains the risk of loss should the
underlying security decline in value. For the covered call writer, substantial
appreciation in the value of the underlying security would result in the
security being "called away." For the secured put writer, substantial
depreciation in the value of the underlying security would result in the
security being "put to" the writer. If a covered call option expires
unexercised, the writer realizes a gain in the amount of the premium received.
If the covered call option writer has to sell the underlying security because of
the exercise of a call option, it realizes a gain or loss from the sale of the
underlying security, with the proceeds being increased by the amount of the
premium.
 
If a secured put option expires unexercised, the writer realizes a gain from the
amount of the premium. If the secured put writer has to buy the underlying
security because of the exercise of the put option, the secured put writer
incurs an unrealized loss to the extent that the current market value of the
underlying security is less than the exercise price of the put option. However,
this would be offset in whole or in part by gain from the premium received.

OVER-THE-COUNTER OPTIONS.  As indicated in the prospectus (see "Investment
Objectives, Policies and Risk Factors"), the Funds may deal in over-the-counter
traded options ("OTC options"). OTC options differ from exchange traded options
in several respects. They are transacted directly with dealers and not with a
clearing corporation, and there is a risk of nonperformance by the dealer as a
result of the insolvency of such dealer or otherwise, in which event a Fund may
experience material losses. However, in writing options the premium is paid in
advance by the dealer. OTC options are available for a greater variety of
securities, and a wider range of expiration dates and exercise prices, than are
exchange traded options. Since there is no exchange, pricing is normally done by
reference to information from market makers, which information is carefully
monitored by the investment manager and verified in appropriate cases.
 
A writer or purchaser of a put or call option can terminate it voluntarily only
by entering into a closing transaction. In the case of OTC options, there can be
no assurance that a continuous liquid secondary market will exist for any
particular option at any specific time. Consequently, a Fund may be able to
realize the value of an OTC option it has purchased only by exercising it or
entering into a closing sale transaction with the dealer that issued it.
Similarly, when a Fund writes an OTC option, it generally can close out that
option prior to its expiration only by entering into a closing purchase
transaction with the dealer to which the Fund originally wrote it. If a covered
call option writer cannot effect a closing transaction, it cannot sell the
underlying security until the option expires or the option is exercised.
Therefore, a covered call option writer of an OTC option may not be able to sell
an underlying security even though it might otherwise be advantageous to do so.
Likewise, a secured put writer of an OTC option may be unable to sell the
securities pledged to secure the put for other investment purposes while it is
obligated as a put writer. Similarly, a purchaser of such put or call option
might also find it difficult to terminate its position on a timely basis in the
absence of a secondary market.
 
The Funds understand the position of the staff of the Securities and Exchange
Commission ("SEC") to be that purchased OTC options and the assets used as
"cover" for written OTC options are illiquid securities. The investment manager
disagrees with this position and has found the dealers with which it engages in
OTC options transactions generally agreeable to and capable of entering into
closing transactions. The Funds have adopted procedures for engaging in OTC
options for the purpose of reducing any potential adverse effect of such
transactions upon the liquidity of the Funds' portfolios. A brief description of
such procedures is set forth below.
 
A Fund will only engage in OTC options transactions with dealers that have been
specifically approved by the investment manager pursuant to procedures adopted
by the Fund's Board of Trustees. The investment manager believes that the
approved dealers should be able to enter into closing transactions if necessary
and, therefore, present minimal credit risks to a Fund. The investment manager
will monitor the creditworthiness of the approved dealers on an ongoing basis. A
Fund currently will not engage in OTC options transactions if the amount
invested by the Fund in OTC options, plus a "liquidity charge" related to OTC
options written by the Fund, plus the amount invested by the Fund in illiquid
securities, would exceed 15% of the Fund's net assets (10% of total assets for
the Mortgage Fund). The "liquidity charge" referred to above is computed as
described below.
 
The Funds anticipate entering into agreements with dealers to which a Fund sells
OTC options. Under these agreements a Fund would have the absolute right to
repurchase the OTC options from the dealer at any time at a price no greater
than a price established under the agreements (the "Repurchase Price"). The
"liquidity charge" referred to above for a specific OTC option transaction will
be the Repurchase Price related to the OTC option less the intrinsic value of
the OTC option. The intrinsic value of an OTC call option for such purposes will
be the amount by which the current market value of the underlying security
exceeds the exercise price. In the case of an OTC put option, intrinsic value
will be the amount by which the exercise price exceeds the current market value
of the underlying security. If there is no such agreement requiring a dealer to
allow the Fund to repurchase a specific OTC option written by the Fund, the
"liquidity charge" will be the current market value of the assets serving as
"cover" for such OTC option.

OPTIONS ON SECURITIES INDICES. A Fund also may purchase and write call and put
options on securities indices in an attempt to hedge against market conditions
affecting the value of securities that the Fund owns or intends to purchase, and
not for speculation. Through the writing or purchase of index options, a Fund
can achieve many of the same objectives as through the use of options on
individual securities. Options on securities indices are similar to options on a
security except that, rather than the right to take or make delivery of a
security at a specified price, an option on a securities index gives the holder
the right to receive, upon exercise of the option, an amount of cash if the
closing level of the securities index upon which the option is based is greater
than, in the case of a call, or less than, in the case of a put, the exercise
price of the option. This amount of cash is equal to such difference between the
closing price of the index and the exercise price of the option. The writer of
the option is obligated, in return for the premium received, to make delivery of
this amount. Unlike security options, all settlements are in cash and gain or
loss depends upon price movements in the market generally (or in a particular
industry or segment of the market), rather than upon price movements in
individual securities. Price movements in securities that the Fund owns or
intends to purchase will probably not correlate perfectly with movements in the
level of an index since the prices of such securities may be affected by
somewhat different factors and, therefore, the Fund bears the risk that a loss
on an index option would not be completely offset by movements in the price of
such securities.
 
When a Fund writes an option on a securities index, it will segregate, and
mark-to-market, eligible securities to the extent required by applicable
regulation. In addition, where the Fund writes a call option on a securities
index at a time when the contract value exceeds the exercise price, the Fund
will segregate and mark-to-market, until the option expires or is closed out,
cash or cash equivalents equal in value to such excess.
 
A Fund may also purchase and sell options on other appropriate indices, as
available, such as foreign currency indices. Options on a securities index
involve risks similar to those risks relating to transactions in financial
futures contracts described below. Also, an option purchased by a Fund may
expire worthless, in which case the Fund would lose the premium paid therefor.
 
FINANCIAL FUTURES CONTRACTS. The Funds may enter into financial futures
contracts for the future delivery of a financial instrument, such as a security,
or an amount of foreign currency or the cash value of a securities index. This
investment technique is designed primarily to hedge (i.e., protect) against
anticipated future changes in market conditions or foreign exchange rates which
otherwise might affect adversely the value of securities or other assets which
the Fund holds or intends to purchase. A "sale" of a futures contract means the
undertaking of a contractual obligation to deliver the securities or the cash
value of an index or foreign currency called for by the contract at a specified
price during a specified delivery period. A "purchase" of a futures contract
means the undertaking of a contractual obligation to acquire the securities or
cash value of an index or foreign currency at a specified price during a
specified delivery period. At the time of delivery, in the case of fixed income
securities pursuant to the contract, adjustments are made to recognize
differences in value arising from the delivery of securities with a different
interest rate than that specified in the contract. In some cases, securities
called for by a futures contract may not have been issued at the time the
contract was written.
 
Although some futures contracts by their terms call for the actual delivery or
acquisition of securities or other assets, in most cases a party will close out
the contractual commitment before delivery of the underlying assets by
purchasing (or selling, as the case may be) on a commodities exchange an
identical futures contract calling for delivery in the same month. Such a
transaction, if effected through a member of an exchange, cancels the obligation
to make or take delivery of the underlying securities or other assets. All
transactions in the futures market are made, offset or fulfilled through a
clearing house associated with the exchange on which the contracts are traded. A
Fund will incur brokerage fees when it purchases or sells contracts, and will be
required to maintain margin deposits. At the time a Fund enters into a futures
contract, it is required to deposit with its custodian, on behalf of the broker,
a specified amount of cash or eligible securities, called "initial margin." The
initial margin required for a futures contract is set by the exchange on which
the contract is traded. Subsequent payments, called "variation margin," to and
from the broker are made on a daily basis as the market price of the futures
contract fluctuates. The costs incurred in connection with futures transactions
could reduce a Fund's return. Futures
 
                                      B-13
<PAGE>   182
 
contracts entail risks. If the investment manager's judgment about the general
direction of markets or exchange rates is wrong, the overall performance may be
poorer than if no such contracts had been entered into.
 
There may be an imperfect correlation between movements in prices of futures
contracts and portfolio assets being hedged. In addition, the market prices of
futures contracts may be affected by certain factors. If participants in the
futures market elect to close out their contracts through offsetting
transactions rather than meet margin requirements, distortions in the normal
relationship between the assets and futures markets could result. Price
distortions could also result if investors in futures contracts decide to make
or take delivery of underlying securities or other assets rather than engage in
closing transactions because of the resultant reduction in the liquidity of the
futures market. In addition, because, from the point of view of speculators, the
margin requirements in the futures markets are less onerous than margin
requirements in the cash market, increased participation by speculators in the
futures market could cause temporary price distortions. Due to the possibility
of price distortions in the futures market and because of the imperfect
correlation between movements in the prices of securities or other assets and
movements in the prices of futures contracts, a correct forecast of market
trends by the investment manager may still not result in a successful hedging
transaction. If any of these events should occur, the Fund could lose money on
the financial futures contracts and also on the value of its portfolio assets.
 
OPTIONS ON FINANCIAL FUTURES CONTRACTS. A Fund may purchase and write call and
put options on financial futures contracts. An option on a futures contract
gives the purchaser the right, in return for the premium paid, to assume a
position in a futures contract at a specified exercise price at any time during
the period of the option. Upon exercise, the writer of the option delivers the
futures contract to the holder at the exercise price. A Fund would be required
to deposit with its custodian initial margin and maintenance margin with respect
to put and call options on futures contracts written by it. A Fund will
establish segregated accounts or will provide cover with respect to written
options on financial futures contracts in a manner similar to that described
under "Options on Securities." Options on futures contracts involve risks
similar to those risks relating to transactions in financial futures contracts
described above. Also, an option purchased by a Fund may expire worthless, in
which case the Fund would lose the premium paid therefor.
 
DELAYED DELIVERY TRANSACTIONS. The Funds may purchase or sell portfolio
securities on a when-issued or delayed delivery basis. When-issued or delayed
delivery transactions involve a commitment by a Fund to purchase or sell
securities with payment and delivery to take place in the future in order to
secure what is considered to be an advantageous price or yield to the Fund at
the time of entering into the transaction. When the Fund enters into a delayed
delivery transaction, it becomes obligated to purchase securities and it has all
of the rights and risks attendant to ownership of a security, although delivery
and payment occur at a later date. The value of fixed income securities to be
delivered in the future will fluctuate as interest rates vary. At the time a
Fund makes the commitment to purchase a security on a when-issued or delayed
delivery basis, it will record the transaction and reflect the liability for the
purchase and the value of the security in determining its net asset value.
Likewise, at the time a Fund makes the commitment to sell a security on a
delayed delivery basis, it will record the transaction and include the proceeds
to be received in determining its net asset value; accordingly, any fluctuations
in the value of the security sold pursuant to a delayed delivery commitment are
ignored in calculating net asset value so long as the commitment remains in
effect. The Fund generally has the ability to close out a purchase obligation on
or before the settlement date, rather than take delivery of the security.
 
To the extent a Fund engages in when-issued or delayed delivery purchases, it
will do so for the purpose of acquiring portfolio securities consistent with the
Fund's investment objective and policies. A Fund reserves the right to sell
these securities before the settlement date if deemed advisable.
 
REGULATORY RESTRICTIONS. To the extent required to comply with applicable
regulation, when purchasing a futures contract, writing a put option or entering
into a delayed delivery purchase or a forward currency exchange purchase, a Fund
will maintain eligible securities in a segregated account. A Fund will use cover
in connection with selling a futures contract.
 
                                      B-14
<PAGE>   183
 
A Fund will not engage in transactions in financial futures contracts or options
thereon for speculation, but only in an attempt to hedge against changes in
interest rates or market conditions affecting the value of securities which the
Fund holds or intends to purchase.
 
FOREIGN CURRENCY OPTIONS. The Diversified, High Yield, Income and Capital and
Opportunity Funds may engage in foreign currency options transactions. A foreign
currency option provides the option buyer with the right to buy or sell a stated
amount of foreign currency at the exercise price at a specified date or during
the option period. A call option gives its owner the right, but not the
obligation, to buy the currency, while a put option gives its owner the right,
but not the obligation, to sell the currency. The option seller (writer) is
obligated to fulfill the terms of the option sold if it is exercised. However,
either seller or buyer may close its position during the option period in the
secondary market for such options any time prior to expiration.
 
A call rises in value if the underlying currency appreciates. Conversely, a put
rises in value if the underlying currency depreciates. While purchasing a
foreign currency option can protect the Fund against an adverse movement in the
value of a foreign currency, it does not limit the gain which might result from
a favorable movement in the value of such currency. For example, if a Fund were
holding securities denominated in an appreciating foreign currency and had
purchased a foreign currency put to hedge against a decline in the value of the
currency, it would not have to exercise its put. Similarly, if the Fund had
entered into a contract to purchase a security denominated in a foreign currency
and had purchased a foreign currency call to hedge against a rise in value of
the currency but instead the currency had depreciated in value between the date
of purchase and the settlement date, the Fund would not have to exercise its
call but could acquire in the spot market the amount of foreign currency needed
for settlement.
 
FOREIGN CURRENCY FUTURES TRANSACTIONS. As part of their financial futures
transactions (see "Financial Futures Contracts" and "Options on Financial
Futures Contracts" above), the Diversified, High Yield, Income and Capital and
Opportunity Funds may use foreign currency futures contracts and options on such
futures contracts. Through the purchase or sale of such contracts, a Fund may be
able to achieve many of the same objectives as through forward foreign currency
exchange contracts more effectively and possibly at a lower cost.
 
Unlike forward foreign currency exchange contracts, foreign currency futures
contracts and options on foreign currency futures contracts are standardized as
to amount and delivery period and are traded on boards of trade and commodities
exchanges. It is anticipated that such contracts may provide greater liquidity
and lower cost than forward foreign currency exchange contracts.
 
FORWARD FOREIGN CURRENCY EXCHANGE CONTRACTS. The Diversified, High Yield, Income
and Capital and Opportunity Funds may engage in forward foreign currency
transactions. A forward foreign currency exchange contract involves an
obligation to purchase or sell a specific currency at a future date, which may
be any fixed number of days ("term") from the date of the contract agreed upon
by the parties, at a price set at the time of the contract. These contracts are
traded directly between currency traders (usually large commercial banks) and
their customers. The investment manager believes that it is important to have
the flexibility to enter into such forward contracts when it determines that to
do so is in the best interests of a Fund. A Fund will not speculate in foreign
currency exchange.
 
If a Fund retains the portfolio security and engages in an offsetting
transaction with respect to a forward contract, the Fund will incur a gain or a
loss (as described below) to the extent that there has been movement in forward
contract prices. If the Fund engages in an offsetting transaction, it may
subsequently enter into a new forward contract to sell the foreign currency.
Should forward prices decline during the period between a Fund's entering into a
forward contract for the sale of foreign currency and the date it enters into an
offsetting contract for the purchase of the foreign currency, the Fund would
realize a gain to the extent the price of the currency it has agreed to sell
exceeds the price of the currency it has agreed to purchase. Should forward
prices increase, the Fund would suffer a loss to the extent the price of the
currency it has agreed to purchase exceeds the price of the currency it has
agreed to sell. Although such contracts tend to minimize the risk of loss due to
a decline in the value of the hedged currency, they also tend to limit any
potential gain that might result should the value of such
 
                                      B-15
<PAGE>   184
 
currency increase. A Fund may have to convert its holdings of foreign currencies
into U.S. Dollars from time to time in order to meet such needs as Fund expenses
and redemption requests. Although foreign exchange dealers do not charge a fee
for conversion, they do realize a profit based on the difference (the "spread")
between the prices at which they are buying and selling various currencies.
 
A Fund will not enter into forward contracts or maintain a net exposure in such
contracts when the Fund would be obligated to deliver an amount of foreign
currency in excess of the value of the Fund's securities or other assets
denominated in that currency. See "Foreign Currency Transactions" under
"Investment Objectives, Policies and Risk Factors--Additional Investment
Information" in the prospectus. A Fund segregates eligible securities to the
extent required by applicable regulation in connection with forward foreign
currency exchange contracts entered into for the purchase of foreign currency.
The Diversified, High Yield, Income and Capital and Opportunity Funds do not
intend to enter into forward contracts for the purchase of a foreign currency if
they would have more than 15% of the value of their total assets committed to
such contracts. A Fund generally will not enter into a forward contract with a
term longer than one year.
 
COLLATERALIZED OBLIGATIONS. A Fund will currently invest in only those
collateralized obligations that are fully collateralized and that meet the
quality standards otherwise applicable to the Fund's investments. Fully
collateralized means that the collateral will generate cash flows sufficient to
meet obligations to holders of the collateralized obligations under even the
most conservative prepayment and interest rate projections. Thus, the
collateralized obligations are structured to anticipate a worst case prepayment
condition and to minimize the reinvestment rate risk for cash flows between
coupon dates for the collateralized obligations. A worst case prepayment
condition generally assumes immediate prepayment of all securities purchased at
a premium and zero prepayment of all securities purchased at a discount.
Reinvestment rate risk may be minimized by assuming very conservative
reinvestment rates and by other means such as by maintaining the flexibility to
increase principal distributions in a low interest rate environment. The
effective credit quality of the collateralized obligations in such instances is
the credit quality of the issuer of the collateral. The requirements as to
collateralization are determined by the issuer or sponsor of the collateralized
obligation in order to satisfy rating agencies, if rated. No Fund currently
intends to invest more than 5% of its total assets in collateralized obligations
that are collateralized by a pool of credit card or automobile receivables or
other types of assets rather than a pool of mortgages, Mortgage-Backed
Securities or U.S. Government Securities. Currently, none of the Funds intends
to invest more than 10% of its total assets in inverse floaters.
 
Payments of principal and interest on the underlying collateral securities are
not passed through directly to the holders of the collateralized obligations as
such. Collateralized obligations often are issued in two or more classes with
varying maturities and stated rates of interest. Because interest and principal
payments on the underlying securities are not passed through directly to holders
of collateralized obligations, such obligations of varying maturities may be
secured by a single portfolio or pool of securities, the payments on which are
used to pay interest on each class and to retire successive maturities in
sequence. These relationships may in effect "strip" the interest payments from
principal payments of the underlying securities and allow for the separate
purchase of either the interest or the principal payments, sometimes called
interest only (IO) and principal only (PO) securities. Collateralized
obligations are designed to be retired as the underlying securities are repaid.
In the event of prepayment on or call of such securities, the class of
collateralized obligation first to mature generally will be paid down first.
Therefore, although in most cases the issuer of collateralized obligations will
not supply additional collateral in the event of such prepayment, there will be
sufficient collateral to secure collateralized obligations that remain
outstanding. It is anticipated that no more than 10% of a Fund's total assets
will be invested in IO and PO securities. Governmentally-issued and
privately-issued IO's and PO's will be considered illiquid for purposes of a
Fund's limitation on illiquid securities, however, the Board of Trustees of a
Fund may adopt guidelines under which governmentally-issued IO's and PO's may be
determined to be liquid.
 
ZERO COUPON GOVERNMENT SECURITIES.  Subject to its investment objective and
policies, a Fund may invest in zero coupon U.S. Government Securities. Zero
coupon bonds are purchased at a discount from the face amount. The buyer
receives only the right to receive a fixed payment on a certain date in the
future and does not receive any
 
                                      B-16
<PAGE>   185
 
periodic interest payments. These securities may include those created directly
by the U.S. Treasury and those created as collateralized obligations through
various proprietary custodial, trust or other relationships (see "Investment
Objectives, Policies and Risk Factors--Additional Investment
Information--Collateralized Obligations" in the prospectus). The effect of
owning instruments which do not make current interest payments is that a fixed
yield is earned not only on the original investment but also, in effect, on all
discount accretion during the life of the obligation. This implicit reinvestment
of earnings at the same rate eliminates the risk of being unable to reinvest
distributions at a rate as high as the implicit yield on the zero coupon bond,
but at the same time eliminates any opportunity to reinvest earnings at higher
rates. For this reason, zero coupon bonds are subject to substantially greater
price fluctuations during periods of changing market interest rates than those
of comparable securities that pay interest currently, which fluctuation is
greater as the period to maturity is longer. Zero coupon bonds created as
collateralized obligations are similar to those created through the U.S.
Treasury, but the former investments do not provide absolute certainty of
maturity or of cash flows after prior classes of the collateralized obligations
are retired. No Fund currently intends to invest more than 5% of its net assets
in zero coupon U.S. Government Securities during the current year.
 
SHORT SALES AGAINST-THE-BOX.  The Adjustable Rate, Diversified and Mortgage
Funds may each make short sales against-the-box. A short sale "against-the-box"
is a short sale in which the Fund owns at least an equal amount of the
securities sold short or securities convertible into or exchangeable for,
without payment of any further consideration, securities of the same issue as,
and at least equal in amount to, the securities sold short. A Fund may engage in
such short sales only to the extent that not more than 10% of the Fund's total
assets (determined at the time of the short sale) is held as collateral for such
sales. No Fund currently intends, however, to engage in such short sales to the
extent that more than 5% of its net assets will be held as collateral therefor
during the current year.
 
INTEREST RATE SWAPS AND SWAP-RELATED PRODUCTS.  Each of the Adjustable Rate and
Opportunity Funds usually will enter into interest rate swaps on a net basis,
i.e., the two payment streams are netted out, with a Fund receiving or paying,
as the case may be, only the net amounts of the two payments. The net amount of
the excess, if any, of the Fund's obligations over its entitlement with respect
to each interest rate swap will be accrued on a daily basis and an amount of
cash or eligible securities having an aggregate net asset value at least equal
to the accrued excess will be maintained in a segregated account by the Fund's
custodian. To the extent that a Fund enters into interest rate swaps on other
than a net basis, the amount maintained in a segregated account will be the full
amount of the Fund's obligations, if any, with respect to such interest rate
swaps, accrued on a daily basis.
 
Each of the Adjustable Rate and Opportunity Funds will not enter into any swap
transaction unless the unsecured senior debt or the claims-paying ability of the
other party thereto is rated in the highest rating category for the Adjustable
Rate Fund, and, within the top three rating categories for the Opportunity Fund,
by at least one nationally recognized rating organization at the time of
entering into such transaction. If there is a default by the other party to such
a transaction, the Fund will have contractual remedies pursuant to the
agreements related to the transaction. The swap market has grown substantially
in recent years with a large number of banks and investment banking firms acting
both as principals and as agents using standardized swap documents. As a result,
the swap market has become relatively liquid. Caps and floors are more recent
innovations for which standardized documents have not yet been developed and,
accordingly, they are less liquid than swaps. It is anticipated that neither the
Adjustable Rate nor Opportunity Fund will invest more than 5% of its total
assets in interest rate caps and floors and that the aggregate notional (agreed
upon) principal amount of interest rate swaps entered into by a Fund and the
aggregate contract value of outstanding futures contracts of a Fund and futures
contracts subject to outstanding options written by a Fund will not exceed 50%
of the Fund's total assets.
 
ADDITIONAL INFORMATION--ADJUSTABLE RATE SECURITIES.  The interest rates paid on
the adjustable rate securities in which the Adjustable Rate Fund invests
generally are readjusted at intervals of one year or less to an increment over
some predetermined interest rate index. There are three main categories of
indices: those based on U.S. Treasury securities, those derived from a
calculated measure such as a cost of funds index or those based on a moving
average of mortgage rates. Commonly used indices include the one-year,
three-year and five-year constant
 
                                      B-17
<PAGE>   186
 
maturity Treasury rates, the three-month Treasury bill rate, the 180-day
Treasury bill rate, rates on longer-term Treasury securities, the 11th District
Federal Home Loan Bank Cost of Funds, the National Median Cost of Funds, the
one-month, three-month, six-month or one-year London Interbank Offered Rate
("LIBOR"), the prime rate of a specific bank or commercial paper rates. Some
indices, such as the one-year constant maturity Treasury rate, closely mirror
changes in market interest rate levels. Others, such as the 11th District Home
Loan Bank Cost of Funds index, tend to lag behind changes in market rate levels
and tend to be somewhat less volatile.
 
The Mortgage-Backed Securities either issued or guaranteed by GNMA, FHLMC or
FNMA ("Certificates") are called pass-through Certificates because a pro rata
share of both regular interest and principal payments (less GNMA's FHLMC's or
FNMA's fees and any applicable loan servicing fees), as well as unscheduled
early prepayments on the underlying mortgage pool, are passed through monthly to
the holder of the Certificate (i.e., the Fund). The principal and interest on
GNMA securities are guaranteed by GNMA and backed by the full faith and credit
of the U.S. Government. FNMA guarantees full and timely payment of all interest
and principal, while FHLMC guarantees timely payment of interest and ultimate
collection of principal. Mortgage-Backed Securities from FNMA and FHLMC are not
backed by the full faith and credit of the United States; however, they are
generally considered to offer minimal credit risks. The yields provided by these
Mortgage-Backed Securities have historically exceeded the yields on other types
of U.S. Government Securities with comparable maturities in large measure due to
the prepayment risk discussed below.
 
If prepayments of principal are made on the underlying mortgages during periods
of rising interest rates, the Adjustable Rate Fund generally will be able to
reinvest such amounts in securities with a higher current rate of return.
However, the Adjustable Rate Fund will not benefit from increases in interest
rates to the extent that interest rates rise to the point where they cause the
current coupon of adjustable rate mortgages held as investments by the
Adjustable Rate Fund to exceed the maximum allowable annual or lifetime reset
limits (or "cap rates") for a particular mortgage. Also, the Adjustable Rate
Fund's net asset value could vary to the extent that current yields on
Mortgage-Backed Securities are different than market yields during interim
periods between coupon reset dates.
 
During periods of declining interest rates, of course, the coupon rates may
readjust downward, resulting in lower yields to the Adjustable Rate Fund.
Further, because of this feature, the value of adjustable rate mortgages is
unlikely to rise during periods of declining interest rates to the same extent
as fixed-rate instruments. As with other Mortgage-Backed Securities, interest
rate declines may result in accelerated prepayment of mortgages, and the
proceeds from such prepayments must be reinvested at lower prevailing interest
rates.
 
One additional difference between adjustable rate mortgages and fixed rate
mortgages is that for certain types of adjustable rate mortgage securities, the
rate of amortization of principal, as well as interest payments, can and does
change in accordance with movements in a specified, published interest rate
index. The amount of interest due to an adjustable rate mortgage security holder
is calculated by adding a specified additional amount, the "margin," to the
index, subject to limitations or "caps" on the maximum and minimum interest that
is charged to the mortgagor during the life of the mortgage or to maximum and
minimum changes to that interest rate during a given period. It is these special
characteristics that are unique to adjustable rate mortgages that the Fund
believes make them attractive investments in seeking to accomplish the
Adjustable Rate Fund's objective.

and trading facilities. ZIML is the subadviser for other Kemper Funds. At times
investment decisions may be made to purchase or sell the same investment
securities for a Fund and for one or more of the other clients managed by ZKI or
its affiliates. When two or more of such clients are simultaneously engaged in
the purchase or sale of the same security through the
 
                                      B-18

same trading facility, the transactions are allocated as to amount and price in
a manner considered equitable to each.
 
National securities exchanges have established limitations governing the maximum
number of options in each class which may be written by a single investor or
group of investors acting in concert. An exchange may order the liquidation of
positions found to be in violation of these limits, and it may impose certain
other sanctions. These position limits may restrict the number of options a Fund
will be able to write on a particular security.
 
The above mentioned factors may have a detrimental effect on the quantities or
prices of securities, options or futures contracts available to a Fund. On the
other hand, the ability of a Fund to participate in volume transactions may
produce better executions for a Fund in some cases.
 
ZKI and ZIML, in effecting purchases and sales of portfolio securities for the
account of a Fund, will implement each Fund's policy of seeking best execution
of orders. ZKI and ZIML may be permitted to pay higher brokerage commissions for
research services as described below. Consistent with this policy, orders for
portfolio transactions are placed with broker-dealer firms giving consideration
to the quality, quantity and nature of each firm's professional services, which
include execution, financial responsibility, responsiveness, clearance
procedures, wire service quotations and statistical and other research
information provided to a Fund and ZKI and its affiliates. Subject to seeking
best execution of an order, brokerage is allocated on the basis of all services
provided. Any research benefits derived are available for all clients of ZKI and
its affiliates. In selecting among firms believed to meet the criteria for
handling a particular transaction, ZKI and ZIML may give consideration to those
firms that have sold or are selling shares of the Funds and of other funds
managed by ZKI or its affiliates, as well as to those firms that provide market,
statistical and other research information to a Fund and ZKI and its affiliates,
although ZKI and ZIML are not authorized to pay higher commissions to firms that
provide such services, except as described below.
 
ZKI and ZIML may in certain instances be permitted to pay higher brokerage
commissions solely for receipt of market, statistical and other research
services as defined in Section 28(e) of the Securities Exchange Act of 1934 and
interpretations thereunder. Such services may include, among other things:
economic, industry or company research reports or investment recommendations;
computerized databases; quotation and execution equipment and software; and
research or analytical computer software and services. Where products or
services have a "mixed use," a good faith effort is made to make a reasonable
allocation of the cost of the products or services in accordance with the
anticipated research and non-research uses and the cost attributable to
non-research use is paid by ZKI or one of its affiliates in cash. Subject to
Section 28(e) and procedures adopted by the Board of Trustees of each Fund, a
Fund (except the Mortgage and Short-Intermediate Government Funds) could pay a
firm that provides research services commissions for effecting a securities
transaction for the Fund in excess of the amount other firms would have charged
for the transaction if ZKI or ZIML determines in good faith that the greater
commission is reasonable in relation to the value of the brokerage and research
services provided by the executing firm viewed in terms either of a particular
transaction or ZKI's or ZIML's overall responsibilities to the Fund and other
clients. Not all of such research services may be useful or of value in advising
a particular Fund. Research benefits will be available for all clients of ZKI
and its affiliates. The investment management fee paid by a Fund to ZKI is not
reduced because these research services are received.

INVESTMENT MANAGER AND UNDERWRITER
 
INVESTMENT MANAGER. Zurich Kemper Investments, Inc. ("ZKI"), 222 South Riverside
Plaza, Chicago, Illinois 60606, is each Fund's investment manager. ZKI is wholly
owned by ZKI Holding Corp. ZKI Holding Corp. is a more than 90% owned subsidiary
of Zurich Holding Company of America, Inc., which is a wholly owned subsidiary
of Zurich Insurance Company, a leading internationally recognized provider of
insurance and financial services in property/casualty and life insurance,
reinsurance and structured financial solutions as well as asset management.
Pursuant to investment management agreements, ZKI acts as each Fund's investment
adviser, manages its investments, administers its business affairs, furnishes
office facilities and equipment, provides clerical, bookkeeping and
administrative services, and permits any of its officers or employees to serve
without compensation as trustees or officers of a Fund if elected to such
positions. Each investment management agreement provides that each Fund pays the
charges and expenses of its operations, including the fees and expenses of the
trustees (except those who are affiliated with ZKI), independent auditors,
counsel, custodian and transfer agent and the cost of share certificates,
reports and notices to shareholders, brokerage commissions or transaction costs,
costs of calculating net asset value, taxes and membership dues. Each Fund bears
the expenses of registration of its shares with the Securities and Exchange
Commission, while Kemper Distributors, Inc. ("KDI"), as principal underwriter,
pays the cost of qualifying and maintaining the qualification of each Fund's
shares for sale under the securities laws of the various states. ZKI has agreed
to reimburse the Government Fund should all operating expenses of the Fund,
including the compensation of ZKI, but excluding taxes, interest, distribution
services fee, extraordinary expenses and brokerage commissions or transaction
costs, exceed 1% of average daily net assets of the fund on an annual basis.
 
The investment management agreements provide that ZKI shall not be liable for
any error of judgment or of law, or for any loss suffered by a Fund in
connection with the matters to which the agreements relate, except a loss
resulting from willful misfeasance, bad faith or gross negligence on the part of
ZKI in the performance of its obligations and duties, or by reason of its
reckless disregard of its obligations and duties under each agreement.
 
Each Fund's investment management agreement continues in effect from year to
year so long as its continuation is approved at least annually by (a) a majority
of the trustees who are not parties to such agreement or interested
 
                                      B-20
<PAGE>   189
 
persons of any such party except in their capacity as trustees of the Fund and
(b) by the shareholders or the Board of Trustees of the Fund. Each Fund's
investment management agreement may be terminated at any time upon 60 days'
notice by either party, or by a majority vote of the outstanding shares of the
Fund, and will terminate automatically upon assignment. If additional Funds
become subject to an investment management agreement, the provisions concerning
continuation, amendment and termination shall be on a Fund by Fund basis.
Additional Funds may be subject to a different agreement.
 
The current investment management fee rates paid by the Funds are in the
prospectus, see "Investment Manager and Underwriter." The investment management
fees paid by each Fund for its last three fiscal years are shown in the table
below (except for the Opportunity Fund which commenced operations on October 1,

FUND SUB-ADVISER. ZIML, 1 Fleet Place, London, U.K. EC4M 7RQ, an affiliate of
ZKI, is the sub-adviser for the foreign securities portion of the Diversified,
High Yield, Opportunity, and Income and Capital Funds. ZIML acts as sub-adviser
pursuant to the terms of a Sub-Advisory Agreement between it and ZKI for each
such Fund.
 
Under the terms of the Sub-Advisory Agreement for a Fund, ZIML renders
investment advisory and management services with regard to that portion of the
Fund's portfolio as may be allocated to ZIML by ZKI from time to time for
management of foreign securities, including foreign currency transactions and
related investments. ZIML may, under the terms of each Sub-Advisory Agreement,
render similar services to others including other investment companies. For its
services, ZIML receives from ZKI a monthly fee at the annual rate of .30% of the
portion of the average daily net assets of each Fund allocated by ZKI to ZIML
for management. ZIML permits any of its officers or employees to serve without
compensation as trustees or officers of the Fund if elected to such positions.
 
Each Sub-Advisory Agreement provides that ZIML will not be liable for any error
of judgment or mistake of law or for any loss suffered by the Fund in connection
with matters to which the Sub-Advisory Agreement relates, except a loss
resulting from willful misfeasance, bad faith or gross negligence on the part of
ZIML in the performance of its duties or from reckless disregard by ZIML of its
obligations and duties under the Sub-Advisory Agreement.
 
Each Sub-Advisory Agreement continues in effect from year to year so long as its
continuation is approved at least annually (a) by a majority of the trustees who
are not parties to such agreement or interested persons of any such party except
in their capacity as trustees of the Fund and (b) by the shareholders or the
Board of Trustees. Each Sub-Advisory Agreement may be terminated at any time for
a Fund upon 60 days notice by ZKI, ZIML or the Board of Trustees, or by a
majority vote of the outstanding shares of the Fund, and will terminate
automatically upon assignment or upon the termination of the Fund's investment
management agreement. If additional Funds become subject to a Sub-Advisory
Agreement, the provisions concerning continuation, amendment and termination
shall be on a Fund-by-Fund basis. Additional Funds may be subject to a different
agreement. The sub-advisory fees paid by ZKI to ZIML for the Diversified, High
Yield and Income and Capital Fund's 1997 fiscal year were $3,821, $0 and $0,
respectively. The Opportunity Fund commenced operations on October 1, 1997.

PRINCIPAL UNDERWRITER. Pursuant to separate underwriting and distribution
services agreements ("distribution agreements"), KDI, a wholly owned subsidiary
of ZKI, is the principal underwriter and distributor for the shares of each Fund
and acts as agent of each Fund in the continuous offering of its shares. KDI
bears all its expenses of providing services pursuant to the distribution
agreement, including the payment of any commissions. Each Fund pays the cost for
the prospectus and shareholder reports to be set in type and printed for
existing shareholders, and KDI, as principal underwriter, pays for the printing
and distribution of copies thereof used in connection with the offering of
shares to prospective investors. KDI also pays for supplementary sales
literature and advertising costs.
 
Each distribution agreement continues in effect from year to year so long as
such continuance is approved for each class at least annually by a vote of the
Board of Trustees of the Fund, including the Trustees who are not interested
persons of the Fund and who have no direct or indirect financial interest in the
agreement. Each agreement automatically terminates in the event of its
assignment and may be terminated for a class at any time without penalty by a
Fund or by KDI upon 60 days notice. Termination by a Fund with respect to a
class may be by vote of a majority of the Board of Trustees, or a majority of
the Trustees who are not interested persons of the Fund and who have no direct
or indirect financial interest in the agreement, or a "majority of the
outstanding voting securities" of the class of the Fund, as defined under the
Investment Company Act of 1940. The agreement may not be amended for a class to
increase the fee to be paid by a Fund with respect to such class without
approval by a majority of the outstanding voting securities of such class of the
Fund and all material amendments must in any event be approved by the Board of
Trustees in the manner described above with respect to the continuation of the
agreement. The provisions concerning the continuation, amendment and termination
of the distribution agreement are on a Fund by Fund basis and for each Fund on a
class by class basis.

CLASS B SHARES AND CLASS C SHARES. Since the distribution agreement provides for
fees charged to Class B and Class C shares that are used by KDI to pay for
distribution services (see the prospectus under "Investment Manager and
Underwriter"), the agreement (the "Plan"), is approved and renewed separately
for the Class B and Class C shares in accordance with Rule 12b-1 under the
Investment Company Act of 1940, which regulates the manner in which an
investment company may, directly or indirectly, bear expenses of distributing
its shares. As of December 1997, each Fund's Rule 12b-1 Plan has been separated
from its distribution agreement.

ADMINISTRATIVE SERVICES. Administrative services are provided to each Fund under
an administrative services agreement ("administrative agreement") with KDI. KDI
bears all its expenses of providing services pursuant to the administrative
agreement between KDI and the Fund, including the payment of service fees. For
the services under the administrative agreement, each Fund pays KDI an
administrative services fee, payable monthly, at the annual rate of up to .25%
of average daily net assets of Class A, B and C shares of the Fund.
 
KDI has entered into related arrangements with various broker-dealer firms and
other service or administrative firms ("firms"), that provide services and
facilities for their customers or clients who are investors of the Fund. The
firms provide such office space and equipment, telephone facilities and
personnel as is necessary or beneficial for providing information and services
to their clients. Such services and assistance may include, but are not limited
to, establishing and maintaining accounts and records, processing purchase and
redemption transactions, answering routine inquiries regarding the Fund,
assistance to clients in changing dividend and investment options, account
designations and addresses and such other administrative services as may be
agreed upon from time to time and permitted by applicable statute, rule or
regulation. With respect to Class A shares, KDI pays each firm a service fee,
normally payable quarterly, at an annual rate of (a) up to .15% (.25% for the
Mortgage and Short-Intermediate Government Funds) of the net assets in Fund
accounts that it maintains and services attributable to Class A shares acquired
prior to October 1, 1993, and (b) up to .25% of net assets of those accounts
that it maintains and services attributable to Class A shares acquired on or
after October 1, 1993, in each case commencing with the month after investment.
With respect to Class B shares and Class C shares, KDI currently advances to
firms the first-year service fee at a rate of up to .25% of the purchase price
of such shares. For periods after the first year, KDI currently intends to pay
firms a service fee at an annual rate of up to .25% (calculated monthly and
normally paid quarterly) of the net assets attributable to Class B and Class C
shares

maintained and serviced by the firm and the fee continues until terminated by
KDI or the Fund. Firms to which service fees may be paid include affiliates of
KDI.
 
The following information concerns the administrative services fee paid by each
Fund to KDI (except the Opportunity Fund which commenced operations on October
1, 1997).

KDI also may provide some of the above services and may retain any portion of
the fee under the administrative agreement not paid to firms to compensate
itself for administrative functions performed for a Fund. Currently, however,
the administrative services fee payable to KDI is based only upon Fund assets in
accounts for which a firm provides administrative services and it is intended
that KDI will pay all the administrative services fee that it receives from a
Fund to firms in the form of service fees. The effective administrative services
fee rate to be charged against all assets of a Fund while this procedure is in
effect will depend upon the proportion of Fund assets that is in accounts for
which a firm of record provides administrative services, as well as (except for
the Mortgage and Short-Intermediate Government Funds), with respect to Class A
shares, the date when shares representing such assets were purchased. The Board
of Trustees of a Fund, in its discretion, may approve basing the fee to KDI on
all Fund assets in the future.
 
Certain trustees or officers of the Funds are also directors or officers of ZKI,
ZIML or KDI as indicated under "Officers and Trustees."

New York 11245, as custodian, has custody of all securities and cash of each
Fund held outside of the United States. They attend to the collection of
principal and income, and payment for and collection of proceeds of securities
bought and sold by each Fund. IFTC is also each Fund's transfer agent and
dividend-paying agent. Pursuant to a services agreement with IFTC, Kemper
Service Company ("KSvC"), an affiliate of ZKI, serves as "Shareholder Service
Agent" of each Fund, and as such, performs all of IFTC's duties as transfer
agent and dividend paying agent. IFTC receives as transfer agent, and pays to
ZKSC, annual account fees of $6 per account plus account set up, transaction and
maintenance charges, annual fees associated with the contingent deferred sales
charge (Class B only) and out-of-pocket expense reimbursement. IFTC's fee is
reduced by certain earnings credits in favor of the Fund. The following shows

audit and report on the Funds' annual financial statements, review certain
regulatory reports and the Funds' federal income tax returns, and perform other
professional accounting, auditing, tax and advisory services when engaged to do
so by the Funds. Shareholders will receive annual audited financial statements
and semi-annual unaudited financial statements.
 
LEGAL COUNSEL. Vedder, Price, Kaufmann & Kammholz, 222 North LaSalle Street,
Chicago, Illinois 60601, serves as legal counsel to each Fund.
 
PURCHASE AND REDEMPTION OF SHARES
 
As described in the Funds' prospectus, shares of a Fund are sold at their public
offering price, which is the net asset value per share of the Fund next
determined after an order is received in proper form plus, with respect to Class
A shares of each Fund, an initial sales charge. The minimum initial investment
is $1,000 and the minimum subsequent investment is $100 but such minimum amounts
may be changed at any time. See the prospectus for certain exceptions to these
minimums. An order for the purchase of shares that is accompanied by a check
drawn on a foreign bank (other than a check drawn on a Canadian bank in U.S.
Dollars) will not be considered in proper form and will not be processed unless
and until the Fund determines that it has received payment of the proceeds of
the check. The time required for such a determination will vary and cannot be
determined in advance.
 
Upon receipt by the Shareholder Service Agent of a request for redemption,
shares of a Fund will be redeemed by the Fund at the applicable net asset value
per share of such Fund as described in the Funds' prospectus.
 
Scheduled variations in or the elimination of the initial sales charge for
purchases of Class A shares or the contingent deferred sales charge for
redemption of Class B or Class C shares by certain classes of persons or through
certain types of transactions as described in the prospectus are provided
because of anticipated economies in sales and sales related efforts.
 
A Fund may suspend the right of redemption or delay payment more than seven days
(a) during any period when the New York Stock Exchange ("Exchange") is closed
other than customary weekend and holiday closings or during any period in which
trading on the Exchange is restricted, (b) during any period when an emergency
exists as a result of which (i) disposal of a Fund's investments is not
reasonably practicable, or (ii) it is not reasonably
 
                                      B-27
<PAGE>   196
 
practicable for the Fund to determine the value of its net assets, or (c) for
such other periods as the Securities and Exchange Commission may by order permit
for the protection of a Fund's shareholders.
 
The conversion of Class B shares to Class A shares may be subject to the
continuing availability of an opinion of counsel, ruling by the Internal Revenue
Service or other assurance acceptable to each Fund to the effect that (a) the
assessment of the distribution services fee with respect to Class B shares and
not Class A shares does not result in the Fund's dividends constituting
"preferential dividends" under the Internal Revenue Code, and (b) that the
conversion of Class B shares to Class A shares does not constitute a taxable
event under the Internal Revenue Code. The conversion of Class B shares to Class
A shares may be suspended if such assurance is not available. In that event, no
further conversions of Class B shares would occur, and shares might continue to
be subject to the distribution services fee for an indefinite period that may
extend beyond the proposed conversion date as described in the prospectus.
 
DIVIDENDS AND TAXES
 
DIVIDENDS. Each Fund normally declares and distributes monthly dividends of net
investment income and distributes any net realized capital gains at least
annually.
 
A Fund may at any time vary its foregoing dividend practices and, therefore,
reserves the right from time to time to either distribute or retain for
reinvestment such of its net investment income and its net short-term and long-
term capital gains as the Board of Trustees of the Fund determines appropriate
under the then current circumstances. In particular, and without limiting the
foregoing, a Fund may make additional distributions of net investment income or
capital gain net income in order to satisfy the minimum distribution
requirements contained in the Internal Revenue Code (the "Code"). Dividends will
be reinvested in shares of the Fund paying such dividends unless shareholders
indicate in writing that they wish to receive them in cash or in shares of other
Kemper Funds as described in the prospectus.
 
The level of income dividends per share (as a percentage of net asset value)
will be lower for Class B and Class C shares than for Class A shares primarily
as a result of the distribution services fee applicable to Class B and Class C
shares. Distributions of capital gains, if any, will be paid in the same amount
for each class.
 
TAXES. Each Fund intends to continue to qualify as a regulated investment
company under Subchapter M of the Code and, if so qualified, will not be liable
for federal income taxes to the extent its earnings are distributed. One of the
Subchapter M requirements to be satisfied is that less than 30% of a Fund's
gross income during its fiscal year must be derived from gains (not reduced by
losses) from the sale or other disposition of securities and certain other
investments held for less than three months. This requirement has been
eliminated by the Taxpayer Relief Act of 1997 for fiscal years beginning after
August 5, 1997. As long as the requirement applies a Fund may be limited in its
options, futures and foreign currency transactions in order to prevent
recognition of such gains.
 
A Fund's options, futures and foreign currency transactions are subject to
special tax provisions that may accelerate or defer recognition of certain gains
or losses, change the character of certain gains or losses, or alter the holding
periods of certain of the Fund's securities.
 
The mark-to-market rules of the Code may require a Fund to recognize unrealized
gains and losses on certain options and futures held by the Fund at the end of
the fiscal year. Under these provisions, 60% of any capital gain or loss
recognized will generally be treated as long-term and 40% as short-term.
However, although certain forward contracts on foreign currency are
marked-to-market, the gain or loss is generally ordinary under Section 988 of
the Code. In addition, the straddle rules of the Code would require deferral of
certain losses realized on positions of a straddle to the extent that the Fund
had unrealized gains in offsetting positions at year end.
 
Gains and losses attributable to fluctuations in the value of foreign currencies
will be characterized generally as ordinary gain or loss under Section 988 of
the Code. For example, if a Fund sold a foreign bond and part of the gain or
loss on the sale was attributable to an increase or decrease in the value of a
foreign currency, then the
 
                                      B-28
<PAGE>   197
 
currency gain or loss may be treated as ordinary income or loss. If such
transactions result in greater net ordinary income, the dividends paid by the
Fund will be increased; if the result of such transactions is lower net ordinary
income, a portion of dividends paid could be classified as a return of capital.
 
At August 31, 1997 the Adjustable Rate Fund had an accumulated net realized
capital loss for federal income tax purposes of approximately $10,622,000, which
is available to offset future taxable capital gains. If not applied, the
carryover expires during the period 1998 through 2004. The Fund does not intend
to distribute realized capital gains until the capital loss carryover is
exhausted.
 
At October 31, 1997 the Diversified Fund had an accumulated net realized capital
loss for federal income tax purposes of approximately $126,968,000, which is
available to offset future taxable capital gains. If not applied, the carryover
expires during the period 1998 through 2003. The Fund does not intend to
distribute realized capital gains until the capital loss carryover is exhausted.
 
At October 31, 1997, the Government Fund had an accumulated net realized capital
loss for federal income tax purposes of approximately $679,036,000, which is
available to offset future taxable capital gains. If not applied, the carryover
expires during the period 1998 through 2004. The Fund does not intend to
distribute realized capital gains until the capital loss carryover is exhausted.
 
At October 31, 1997, the Income and Capital Fund had an accumulated net realized
capital loss for federal income tax purposes of approximately $16,124,000, which
is available to offset future taxable capital gains. If not applied, the
carryover expires during the period 2002 through 2003. The Fund does not intend
to distribute realized capital gains until the capital loss carryover is
exhausted.
 
At September 30, 1997, the High Yield Fund had an accumulated net realized
capital loss for federal income tax purposes of approximately $151,654,000,
which is available to offset future taxable capital gains. If not applied, the
carryover expires during the period 1998 through 2006. The Fund does not intend
to distribute realized capital gains until the capital loss carryover is
exhausted.
 
At September 30, 1997, the Mortgage Fund had an accumulated net realized capital
loss for federal income tax purposes of approximately $894,044,000, which is
available to offset future taxable capital gains. If not applied, the carryover
expires during the period 1998 through 2006. The Fund does not intend to
distribute realized capital gains until the capital loss carryover is exhausted.
 
At September 30, 1997, the Short-Intermediate Government Fund had an accumulated
net realized capital loss for federal income tax purposes of approximately
$22,500,000, which is available to offset future taxable capital gains. If not
applied, the carryover expires during the period 2002 through 2006. The Fund
does not intend to distribute realized capital gains until the capital loss
carryover is exhausted.
 
A 4% excise tax is imposed on the excess of the required distribution for a
calendar year over the distributed amount for such calendar year. The required
distribution is the sum of 98% of a Fund's net investment income for the
calendar year plus 98% of its capital gain net income for the one-year period
ending October 31, plus any undistributed net investment income from the prior
calendar year, plus any undistributed capital gain net income from the one year
period ended October 31 in the prior calendar year, minus any overdistribution
in the prior calendar year. For purposes of calculating the required
distribution, foreign currency gains or losses occurring after October 31 are
taken into account in the following calendar year. Each Fund intends to declare
or distribute dividends during the appropriate periods of an amount sufficient
to prevent imposition of the 4% excise tax.
 
A shareholder who redeems shares of a Fund will recognize capital gain or loss
for federal income tax purposes measured by the difference between the value of
the shares redeemed and the adjusted cost basis of the shares. Any loss
recognized on the redemption of Fund shares held six months or less will be
treated as long-term capital loss to the extent that the shareholder has
received any long-term capital gain dividends on such shares. A shareholder who
has redeemed shares of a Fund (other than shares of the Kemper Cash Reserves
Fund not acquired by exchange from another Kemper Mutual Fund) or other Kemper
Mutual Fund listed in the prospectus
 
                                      B-29
<PAGE>   198
 
under "Special Features--Class A Shares--Combined Purchases" may reinvest the
amount redeemed at net asset value at the time of the reinvestment in shares of
any Fund or in shares of a Kemper Mutual Fund within six months of the
redemption as described in the prospectus under "Redemption or Repurchase of
Shares--Reinvestment Privilege." If redeemed shares were purchased after October
3, 1989 and were held less than 91 days, then the lesser of (a) the sales charge
waived on the reinvested shares, or (b) the sales charge incurred on the
redeemed shares, is included in the basis of the reinvested shares and is not
included in the basis of the redeemed shares. If a shareholder realized a loss
on the redemption or exchange of a Fund's shares and reinvests in shares of the
same Fund within 30 days before or after the redemption or exchange, the
transactions may be subject to the wash sale rules resulting in a postponement
of the recognition of such loss for federal income tax purposes. An exchange of
a Fund's shares for shares of another fund is treated as a redemption and
reinvestment for federal income tax purposes upon which gain or loss may be
recognized.
 
A Fund's investment income derived from foreign securities and certain American
Depositary Receipts may be subject to foreign income taxes withheld at the
source. Because the amount of a Fund's investments in various countries will
change from time to time, it is not possible to determine the effective rate of
such taxes in advance.
 
Shareholders who are non-resident aliens are subject to U.S. withholding tax on
ordinary income dividends (whether received in cash or shares) at a rate of 30%
or such lower rate as prescribed by any applicable tax treaty.
 
PERFORMANCE
 
As described in the prospectus, each Fund's historical performance or return for
a class of shares may be shown in the form of "yield" and "average annual total
return" and "total return" figures. These various measures of performance are
described below. Performance information will be computed separately for each
class. ZKI agreed to waive its management fee and to absorb certain operating
expenses for the Adjustable Rate Fund for the periods and to the extent
specified in this Statement of Additional Information. See "Investment Manager
and Underwriter." Because of this waiver and expense absorption, the performance
results for the Adjustable Rate Fund may be shown with and without the effect of
this waiver and expense absorption. Performance results not giving effect to
waivers and expense absorptions will be lower.
 
Yield is a measure of the net investment income per share earned over a specific
one month or 30-day period expressed as a percentage of the maximum offering
price of a Fund's shares at the end of the period. Average annual total return
and total return measure both the net investment income generated by, and the
effect of any realized or unrealized appreciation or depreciation of, the
underlying investments in the Fund's portfolio.
 
A Fund's yield is computed in accordance with a standardized method prescribed
by rules of the Securities and Exchange Commission. Each Fund's yield shown
below is based on the one month period ended as noted (except for the
Opportunity Fund which commenced operations on October 1, 1997).

Each Fund's yield is computed by dividing the net investment income per share
earned during the specified one month or 30-day period by the maximum offering
price per share (which is net asset value for Class B and Class C shares) on the
last day of the period, according to the following formula:

Where: a = dividends and interest earned during the period.
       b = expenses accrued for the period (net of reimbursements).
       c = the average daily number of shares outstanding during the period that
           were entitled to receive dividends.
 
       d = the maximum offering price per share on the last day of the period
           (which is net asset value for Class B and Class C shares).
 
In computing the foregoing yield, each Fund follows certain standardized
accounting practices specified by Securities and Exchange Commission rules.
These practices are not necessarily consistent with those that each Fund uses to
prepare its annual and interim financial statements in conformity with generally
accepted accounting principles.
 
Each Fund's average annual total return quotation is computed in accordance with
a standardized method prescribed by rules of the Securities and Exchange
Commission. The average annual total return for a Fund for a specific period is
found by first taking a hypothetical $1,000 investment ("initial investment") in
the Fund's shares on the first day of the period, adjusting to deduct the
maximum sales charge (in the case of Class A shares), and computing the
"redeemable value" of that investment at the end of the period. The redeemable
value in the case of Class B shares or Class C shares includes the effect of the
applicable contingent deferred sales charge that may be imposed at the end of
the period. The redeemable value is then divided by the initial investment, and
this quotient is taken to the Nth root (N representing the number of years in
the period) and 1 is subtracted from the result, which is then expressed as a
percentage. The calculation assumes that all income and capital gains dividends
paid by the Fund have been reinvested at net asset value on the reinvestment
dates during the period. Average annual total return may also be calculated
without deducting the maximum sales charge.
 
Calculation of a Fund's total return is not subject to a standardized formula,
except when calculated for purposes of the Fund's "Financial Highlights" table
in the Fund's financial statements and prospectus. Total return performance for
a specific period is calculated by first taking a hypothetical investment
("initial investment") in a Fund's shares on the first day of the period, either
adjusting or not adjusting to deduct the maximum sales charge (in the case of
Class A shares), and computing the "ending value" of that investment at the end
of the period. The total return percentage is then determined by subtracting the
initial investment from the ending value and dividing the remainder by the
initial investment and expressing the result as a percentage. The ending value
in the case of Class B and Class C shares may or may not include the effect of
the applicable contingent deferred sales charge that may be imposed at the end
of the period. The calculation assumes that all income and capital gains
dividends paid by the Fund have been reinvested at net asset value on the
reinvestment dates during the period. Total return may also be shown as the
increased dollar value of the hypothetical investment over the period. Total
return calculations that do not include the effect of the sales charge would be
reduced if such charge were included.
 
A Fund's performance figures are based upon historical results and are not
representative of future performance. Each Fund's Class A shares are sold at net
asset value plus a maximum sales charge of 4.5% of the offering price (3.5% for
the Adjustable Rate and Short-Intermediate Government Funds). Class B and Class
C shares are sold at net asset value. Redemptions of Class B shares may be
subject to a contingent deferred sales charge that is 4% in the first year
following the purchase, declines by a specified percentage each year thereafter
and becomes zero after six years. Redemption of Class C shares may be subject to
a 1% contingent deferred sales charge in the first year following purchase.
Returns and net asset value will fluctuate. Factors affecting each Fund's
performance include general market conditions, operating expenses and investment
management. Any additional fees charged by a dealer or other financial services
firm would reduce the returns described in this section. Shares of each Fund are
redeemable at the then current net asset value, which may be more or less than
original cost.
 
The figures below show performance information for the Funds for various
periods. Comparative information with respect to certain indices is also
included. Please note the differences and similarities between the investments
which a Fund may purchase and the investments measured by the applicable
indices. The Consumer Price Index is

generally considered to be a measure of inflation. The Lehman Brothers
Adjustable Rate Index generally represents the performance of adjustable rate
mortgages during various market conditions. The Lehman Brothers Aggregate Bond
Index generally represents the performance of intermediate and long-term
government bonds and investment grade corporate debt securities and
mortgage-backed securities during various market conditions. The Lehman Brothers
Government/Corporate Bond Index generally represents the performance of
intermediate and long-term government and investment grade corporate debt
securities during various market conditions. The Merrill Lynch Market Weighted
Index generally represents the performance of short- and intermediate-term
Treasury and GNMA securities during various market conditions. The Salomon
Brothers High Grade Corporate Bond Index generally represents the performance of
high grade long-term corporate bonds during various market conditions. The
Salomon Brothers Long-Term High Yield Index generally represents the performance
of high yield debt securities during various market conditions. The Salomon
Brothers 30 Year GNMA Index generally represents the performance of GNMA 30-year
pass-through mortgages. The foregoing bond indices are unmanaged. The market
prices and yields of corporate and government bonds will fluctuate. The net
asset values and returns of each class of shares of the Funds will also
fluctuate. No adjustment has been made for taxes payable on dividends. The
period indicated was one of fluctuating securities prices and interest rates. As
indicated previously, the Opportunity Fund commenced operations on October 1,
1997.

Capital Fund and Mortgage Fund and 3.5% for the Adjustable Rate Fund and
Short-Intermediate Government Fund. The Initial Investment for Class B and Class

based upon the schedule for shares sold currently, see "Redemption or Repurchase
of Shares" in the prospectus. No adjustments were made to Class C shares.

Investors may want to compare the performance of a Fund to that of certificates
of deposit issued by banks and other depository institutions. Certificates of
deposit represent an alternative income producing product. Certificates of
deposit may offer fixed or variable interest rates and principal is guaranteed
and may be insured. Withdrawal of deposits prior to maturity will normally be
subject to a penalty. Rates offered by banks and other depository institutions
are subject to change at any time specified by the issuing institution. The
shares of a Fund are not insured and net asset value as well as yield will
fluctuate. Shares of a Fund are redeemable at net asset value which may be more
or less than original cost. The bonds in which the Funds invest are generally of
longer term than most certificates of deposit and may reflect longer term market
interest rate fluctuations.
 
Investors also may want to compare the performance of a Fund to that of U.S.
Treasury bills, notes or bonds because such instruments represent alternative
income producing products. Treasury obligations are issued in selected
denominations. Rates of Treasury obligations are fixed at the time of issuance
and payment of principal and interest is backed by the full faith and credit of
the U.S. Treasury. The market value of such instruments will generally fluctuate
inversely with interest rates prior to maturity and will equal par value at
maturity. As noted in the prospectus, the government guarantee of the bonds in
the Adjustable Rate, Government, Mortgage and Short-Intermediate Government
Funds does not guarantee the market value of their respective shares. The net
asset value of a Fund will fluctuate. Shares of a Fund are redeemable at net
asset value which may be more or less than original cost. Each Fund's yield will
also fluctuate.
 
From time to time, the Adjustable Rate Fund may compare its yield or price
volatility to various securities, such as U.S. Government Securities, or to
certain indices including, but not limited to, the J.P. Morgan one-, three-, and
five-year constant maturity Treasury yield indices, which are based on estimated
Treasury security yields adjusted to constant maturity and the Federal Home Loan
Bank Board 11th District Cost of Funds Index (COFI), which represents the
weighted average cost of funds for savings institutions in Arizona, California
and Nevada and is based on the one month annualized yield of savings deposits,
Federal Home Loan Advances and other borrowings, such as repurchase agreements.
 
The following tables illustrate an assumed $10,000 investment in Class A shares
of each Fund other than the Mortgage, Opportunity and Short-Intermediate
Government Funds, which includes the current maximum sales charge of 4.5% (3.5%
for the Adjustable Rate Fund), with income and capital gain dividends reinvested
in additional shares. The tables for the Mortgage and Short-Intermediate
Government Funds illustrate an assumed $10,000 investment in Class B shares of
these Funds, with income and capital gain dividends reinvested in additional
shares, and do not include the effect of the contingent deferred sales charge.
Each table covers the period from commencement of operations of the Fund to
December 31, 1996.

SHAREHOLDER RIGHTS
 
The Funds generally are not required to hold meetings of their shareholders.
Under the Agreement and Declaration of Trust of each Fund ("Declaration of
Trust"), however, shareholder meetings will be held in connection with the
following matters: (a) the election or removal of trustees if a meeting is
called for such purpose; (b) the adoption of any contract for which shareholder
approval is required by the Investment Company Act of 1940 ("1940 Act"); (c) any
termination of the Fund or a class to the extent and as provided in the
Declaration of Trust; (d) any amendment of the Declaration of Trust (other than
amendments changing the name of the Fund, supplying any omission, curing any
ambiguity or curing, correcting or supplementing any defective or inconsistent
provision thereof); (e) (with respect to the Mortgage and Short-Intermediate
Government Funds only) as to whether a court action, proceeding or claim should
or should not be brought or maintained derivatively or as a class on behalf of
the Fund or the shareholders, to the same extent as the stockholders of a
Massachusetts business corporation; and (f) such additional matters as may be
required by law, the Declaration of Trust, the By- laws of the Fund, or any
registration of the Fund with the Securities and Exchange Commission or any
state, or as the trustees may consider necessary or desirable. The shareholders
also would vote upon changes in fundamental investment objectives, policies or
restrictions.
 
                                      B-51
<PAGE>   220
 
Each trustee serves until the next meeting of shareholders, if any, called for
the purpose of electing trustees and until the election and qualification of a
successor or until such trustee sooner dies, resigns, retires or is removed by a
majority vote of the shares entitled to vote (as described below) or a majority
of the trustees. In accordance with the 1940 Act (a) each Fund will hold a
shareholder meeting for the election of trustees at such time as less than a
majority of the trustees have been elected by shareholders, and (b) if, as a
result of a vacancy in the Board of Trustees, less than two-thirds of the
trustees have been elected by the shareholders, that vacancy will be filled only
by a vote of the shareholders.
 
Trustees may be removed from office by a vote of the holders of a majority of
the outstanding shares at a meeting called for that purpose, which meeting shall
be held upon the written request of the holders of not less than 10% of the
outstanding shares. Upon the written request of ten or more shareholders who
have been such for at least six months and who hold shares constituting at least
1% of the outstanding shares of a Fund stating that such shareholders wish to
communicate with the other shareholders for the purpose of obtaining the
signatures necessary to demand a meeting to consider removal of a trustee, each
Fund has undertaken to disseminate appropriate materials at the expense of the
requesting shareholders.
 
Each Fund's Declaration of Trust provides that the presence at a shareholder
meeting in person or by proxy of at least 30% of the shares entitled to vote on
a matter shall constitute a quorum. Thus, a meeting of shareholders of a Fund
could take place even if less than a majority of the shareholders were
represented on its scheduled date. Shareholders would in such a case be
permitted to take action which does not require a larger vote than a majority of
a quorum, such as the election of trustees and ratification of the selection of
auditors. Some matters requiring a larger vote under the Declaration of Trust,
such as termination or reorganization of a Fund and certain amendments of the
Declaration of Trust, would not be affected by this provision; nor would matters
which under the 1940 Act require the vote of a "majority of the outstanding
voting securities" as defined in the 1940 Act.
 
Each Fund's Declaration of Trust specifically authorizes the Board of Trustees
to terminate the Fund or any Portfolio or class by notice to the shareholders
without shareholder approval.
 
Under Massachusetts law, shareholders of a Massachusetts business trust could,
under certain circumstances, be held personally liable for obligations of a
Fund. The Declaration of Trust, however, disclaims shareholder liability for
acts or obligations of each Fund and requires that notice of such disclaimer be
given in each agreement, obligation, or instrument entered into or executed by a
Fund or the Fund's trustees. Moreover, the Declaration of Trust provides for
indemnification out of Fund property for all losses and expenses of any
shareholder held personally liable for the obligations of a Fund and each Fund
will be covered by insurance which the trustees consider adequate to cover
foreseeable tort claims. Thus, the risk of a shareholder incurring financial
loss on account of shareholder liability is considered by ZKI remote and not
material, since it is limited to circumstances in which a disclaimer is
inoperative and such Fund itself is unable to meet its obligations.

RATINGS OF INVESTMENTS
 
                            COMMERCIAL PAPER RATINGS
 
Commercial paper rated by Standard & Poor's Corporation ("S&P") has the
following characteristics: Liquidity ratios are adequate to meet cash
requirements. Long-term senior debt is rated "A" or better. The issuer has
access to at least two additional channels of borrowing. Basic earnings and cash
flow have an upward trend with allowance made for unusual circumstances.
Typically, the issuer's industry is well established and the issuer has a strong
position within the industry. The reliability and quality of management are
unquestioned. Relative strength or weakness of the above factors determine
whether the issuer's commercial paper is rated A-1 or A-2.
 
The ratings Prime-1 and Prime-2 are the two highest commercial paper ratings
assigned by Moody's Investors Service, Inc. ("Moody's"). Among the factors
considered by it in assigning ratings are the following: (1) evaluation of the
management of the issuer; (2) economic evaluation of the issuer's industry or
industries and an appraisal of speculative-type risks which may be inherent in
certain areas; (3) evaluation of the issuer's products in relation to
competition and customer acceptance; (4) liquidity; (5) amount and quality of
long-term debt; (6) trend of earnings over a period of ten years; (7) financial
strength of a parent company and the relationships which exist with the issuer;
and (8) recognition by the management of obligations which may be present or may
arise as a result of public interest questions and preparations to meet such
obligations. Relative strength or weakness of the above factors determines
whether the issuer's commercial paper is rated Prime-1 or 2.
 
                                CORPORATE BONDS
                   STANDARD & POOR'S CORPORATION BOND RATINGS
 
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 higher rated issues 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 the 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.
 
BB, B, CCC, CC, C. Debt rated BB, B, CCC, CC and C is regarded, on balance, as
predominantly speculative with respect to capacity to pay interest and repay
principal in accordance with the terms of the obligation. BB indicates the
lowest 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.
 
CI. The rating CI is reserved for income bonds on which no interest is being
paid.
 
D. Debt rated D is in default, and payment of interest and/or repayment of
principal is in arrears.
 
                  MOODY'S INVESTORS SERVICE, INC. BOND 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-edge." 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.
 
                                      B-55
<PAGE>   224
 
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 risks appear somewhat larger than in 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 sometime 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.

                             Massachusetts. The Fund offers four classes of
                             shares. Class A shares are sold to investors
                             subject to an initial sales charge. Class B shares
                             are sold without an initial sales charge but are
                             subject to higher ongoing expenses than Class A
                             shares and a contingent deferred sales charge
                             payable upon certain redemptions. Class B shares
                             automatically convert to Class A shares six years
                             after issuance. Class C shares are sold without an
                             initial sales charge but are subject to higher
                             ongoing expenses than Class A shares and a
                             contingent deferred sales charge payable upon
                             certain redemptions within one year of purchase.
                             Class C Shares do not convert into another class.
                             Class I shares (none sold through February 28,
                             1998) are offered to a limited group of investors,
                             are not subject to initial or contingent deferred
                             sales charges and have lower ongoing expenses than
                             other classes. Differences in class expenses will
                             result in the payment of different per share income
                             dividends by class. All shares of the Fund have
                             equal rights with respect to voting, dividends and
                             assets, subject to class specific preferences.

2    SIGNIFICANT
     ACCOUNTING POLICIES     INVESTMENT VALUATION. Investments are stated at
                             value. Fixed income securities are valued by using
                             market quotations, or independent pricing services
                             that use prices provided by market makers or
                             estimates of market values obtained from yield data
                             relating to instruments or securities with similar
                             characteristics. Exchange traded financial futures
                             and options are valued at the settlement price
                             established each day by the board of trade or
                             exchange on which they are traded. Over-the-counter
                             traded fixed income options are valued based upon
                             prices provided by market makers. Other securities
                             and assets are valued at fair value as determined
                             in good faith by the Board of Trustees.
 
                             INVESTMENT TRANSACTIONS AND INVESTMENT
                             INCOME. Investment transactions are accounted for
                             on the trade date (date the order to buy or sell is
                             executed). Interest income is recorded on the
                             accrual basis and includes discount amortization on
                             all fixed income securities and premium
                             amortization on mortgage-backed securities.
                             Realized gains and losses from investment
                             transactions are reported on an identified cost
                             basis.
 
                             The Fund may purchase securities with delivery or
                             payment to occur at a later date. At the time the
                             Fund enters into a commitment to purchase a
                             security, the transaction is recorded and the value
                             of the security is reflected in the net asset
                             value. The value of the security may vary with
                             market fluctuations. No interest accrues to the
                             Fund until payment takes place. At the time the
                             Fund enters into this type of transaction it is
                             required to segregate cash or other liquid assets
                             equal to the value of the securities purchased. At
                             February 28, 1998, the Fund had $8,113,000 in
                             purchase commitments outstanding (11% of net
                             assets) with a corresponding amount of assets
                             segregated.
 
                             FUND SHARE VALUATION. Fund shares are sold and
                             redeemed on a continuous basis at net asset value
                             (plus an initial sales charge on most sales of
                             Class A shares). Proceeds payable on redemption of
                             Class B and Class C shares will be reduced by the
                             amount of any applicable contingent deferred sales
                             charge. On each day the New York Stock Exchange is
                             open for trading, the net asset value per share is
                             determined as of the earlier of 3:00 p.m. Chicago
                             time or the close of the Exchange. The net asset
                             value per share is determined separately for each
                             class

                             FEDERAL INCOME TAXES. The Fund has complied with
                             the special provisions of the Internal Revenue Code
                             available to investment companies for the six
                             months ended February 28, 1998. The accumulated net
                             realized loss on sales of investments for federal
                             income tax purposes at February 28, 1998, amounting
                             to approximately $10,681,000, is available to
                             offset future taxable gains. If not applied, the
                             loss carryover expires during the period 1998
                             through 2006.
 
                             DIVIDENDS TO SHAREHOLDERS. The Fund declares and
                             pays dividends of net investment income monthly and
                             any net realized capital gains annually, which are
                             recorded on the ex-dividend date. Dividends are
                             determined in accordance with income tax principles
                             which may treat certain transactions differently
                             than generally accepted accounting principles.
 
                             EQUALIZATION ACCOUNTING. A portion of proceeds from
                             sales and cost of redemptions of Fund shares is
                             credited or charged to undistributed net investment
                             income so that income per share available for
                             distribution is not affected by sales or
                             redemptions of shares.

3    TRANSACTIONS
     WITH AFFILIATES         INVESTMENT MANAGER COMBINATION. Effective December
                             31, 1997, Zurich Insurance Company, the parent of
                             Zurich Kemper Investments, Inc. (ZKI), acquired a

                             (Scudder), another major investment manager. As a
                             result of this transaction, the operations of ZKI
                             were combined with Scudder to form a new global
                             investment organization named Scudder Kemper
                             Investments, Inc. (Scudder Kemper). The transaction
                             resulted in the termination of the Fund's
                             investment management agreement with ZKI, however,
                             a new investment management agreement between the

                             Board of Trustees and by the Fund's Shareholders.
                             The new management agreement, which was effective
                             December 31, 1997, is the same in all material
                             respects as the previous management agreement,
                             except that Scudder Kemper is the new investment
                             adviser to the Fund. In addition, the names of the
                             Fund's principal underwriter and shareholder

NOTES: Scudder Kemper agreed to waive its management fee and absorb certain
operating expenses during a portion of the fiscal year ended August 31, 1992.
Thereafter, these expenses were gradually reinstated from December 31, 1992

REPORT OF INDEPENDENT AUDITORS
 
THE BOARD OF TRUSTEES AND SHAREHOLDERS
KEMPER ADJUSTABLE RATE U.S. GOVERNMENT FUND
 
  We have audited the accompanying statement of assets and liabilities,
including the portfolio of investments, of Kemper Adjustable Rate U.S.
Government Fund as of August 31, 1997, the related statement of operations for
the year then ended, the statement of changes in net assets for each of the two
years in the period then ended, and the financial highlights for each of the
fiscal periods since 1993. These financial statements and financial highlights
are the responsibility of the Fund's management. Our responsibility is to
express an opinion on these financial statements and financial highlights based
on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of investments owned as of
August 31, 1997, by correspondence with the custodian and brokers. An audit also
includes assessing the accounting principles used and significant estimates made
by management, as well as evaluating the overall financial statement
presentation. We believe that our audits provide a reasonable basis for our
opinion.
 
  In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of Kemper
Adjustable Rate U.S. Government Fund at August 31, 1997, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended, and the financial highlights for each of
the fiscal periods since 1993, in conformity with generally accepted accounting
principles.

1    DESCRIPTION OF THE
     FUND                    Kemper Adjustable Rate U.S. Government Fund is an
                             open-end management investment company organized as
                             a business trust under the laws of Massachusetts.
                             The Fund offers four classes of shares. Class A
                             shares are sold to investors subject to an initial
                             sales charge. Class B shares are sold without an
                             initial sales charge but are subject to higher
                             ongoing expenses than Class A shares and a
                             contingent deferred sales charge payable upon
                             certain redemptions. Class B shares automatically
                             convert to Class A shares six years after issuance.
                             Class C shares are sold without an initial sales
                             charge but are subject to higher ongoing expenses
                             than Class A shares and a contingent deferred sales
                             charge payable upon certain redemptions within one
                             year of purchase. Class C Shares do not convert
                             into another class. Class I shares (none sold
                             through August 31, 1997) are offered to a limited
                             group of investors, are not subject to initial or
                             contingent deferred sales charges and have lower
                             ongoing expenses than other classes. Differences in
                             class expenses will result in the payment of
                             different per share income dividends by class. All
                             shares of the Fund have equal rights with respect
                             to voting, dividends and assets, subject to class
                             specific preferences.

2    SIGNIFICANT
     ACCOUNTING POLICIES     INVESTMENT VALUATION. Investments are stated at
                             value. Fixed income securities are valued by using
                             market quotations, or independent pricing services
                             that use prices provided by market makers or
                             estimates of market values obtained from yield data
                             relating to instruments or securities with similar
                             characteristics. Exchange traded financial futures
                             and options are valued at the settlement price
                             established each day by the board of trade or
                             exchange on which they are traded. Over-the-counter
                             traded fixed income options are valued based upon
                             prices provided by market makers. Other securities
                             and assets are valued at fair value as determined
                             in good faith by the Board of Trustees.
 
                             INVESTMENT TRANSACTIONS AND INVESTMENT
                             INCOME. Investment transactions are accounted for
                             on the trade date (date the order to buy or sell is
                             executed). Interest income is recorded on the
                             accrual basis and includes discount amortization on
                             all fixed income securities and premium
                             amortization on mortgage-backed securities.
                             Realized gains and losses from investment
                             transactions are reported on an identified cost
                             basis.
 
                             The Fund may purchase securities with delivery or
                             payment to occur at a later date. At the time the
                             Fund enters into a commitment to purchase a
                             security, the transaction is recorded and the value
                             of the security is reflected in the net asset
                             value. The value of the security may vary with
                             market fluctuations. No interest accrues to the
                             Fund until payment takes place. At the time the
                             Fund enters into this type of transaction it is
                             required to segregate cash or other liquid assets
                             equal to the value of the securities purchased. At
                             August 31, 1997, the Fund had $13,443,000 in
                             purchase commitments outstanding (16% of net
                             assets) with a corresponding amount of assets
                             segregated.
 
                             FUND SHARE VALUATION. Fund shares are sold and
                             redeemed on a continuous basis at net asset value
                             (plus an initial sales charge on most sales of
                             Class A shares). Proceeds payable on redemption of
                             Class B and Class C shares will be reduced by the
                             amount of any applicable contingent deferred sales
                             charge. On each day the New York Stock Exchange is
                             open for trading, the net asset value per share is
                             determined as of the earlier of 3:00 p.m. Chicago
                             time or the close of the Exchange. The net asset
                             value per share is determined separately for each
                             class

                             by dividing the Fund's net assets attributable to
                             that class by the number of shares of the class
                             outstanding.
 
                             FEDERAL INCOME TAXES. The Fund has complied with
                             the special provisions of the Internal Revenue Code
                             available to investment companies and therefore no
                             federal income tax provision is required. The
                             accumulated net realized loss on sales of
                             investments for federal income tax purposes at
                             August 31, 1997, amounting to approximately
                             $10,622,000, is available to offset future taxable
                             gains. If not applied, the loss carryover expires
                             during the period 1998 through 2004.
 
                             DIVIDENDS TO SHAREHOLDERS. The Fund declares and
                             pays dividends of net investment income monthly and
                             any net realized capital gains annually, which are
                             recorded on the ex-dividend date. Dividends are
                             determined in accordance with income tax principles
                             which may treat certain transactions differently
                             than generally accepted accounting principles.
 
                             EQUALIZATION ACCOUNTING. A portion of proceeds from
                             sales and cost of redemptions of Fund shares is
                             credited or charged to undistributed net investment
                             income so that income per share available for
                             distribution is not affected by sales or
                             redemptions of shares.

6    FINANCIAL FUTURES
     CONTRACTS               The Fund has entered into exchange traded financial
                             futures contracts in order to protect itself from
                             anticipated market conditions and, as such, bears
                             the risk that arises from entering into these
                             contracts.
 
                             At the time the Fund enters into a futures
                             contract, it is required to make a margin deposit
                             with its custodian. Subsequently, gain or loss is
                             recognized and payments are made on a daily basis
                             between the Fund and its broker as the market value
                             of the futures contract fluctuates. At August 31,
                             1997, the market value of assets pledged by the
                             Fund to cover margin requirements for open futures
                             positions was $89,000. The Fund also had liquid
                             securities in its portfolio in excess of the face
                             amount of the following short futures position open
                             at August 31, 1997:

during a portion of the fiscal year ended August 31, 1992. Thereafter, these
expenses were gradually reinstated from December 31, 1992 through January 31,
1994. Without this agreement, the ratios of expenses and net investment income
to average net assets for Class A shares would have been .99% and 3.90% for the
year ended August 31, 1994, and .95% and 4.70% for the year ended August 31,
1993.
 
Total return does not reflect the effect of any sales charges.

1    DESCRIPTION OF THE
     FUND                    Kemper Short-Intermediate Government Fund is a
                             separate series of Kemper Portfolios, an open-end
                             management investment company organized as a
                             business trust under the laws of Massachusetts. The
                             Fund offers four classes of shares. Class A shares
                             are sold to investors subject to an initial sales
                             charge. Class B shares are sold without an initial
                             sales charge but are subject to higher ongoing
                             expenses than Class A shares and a contingent
                             deferred sales charge payable upon certain
                             redemptions. Class B shares automatically convert
                             to Class A shares six years after issuance. Class C
                             shares are sold without an initial sales charge but
                             are subject to higher ongoing expenses than Class A
                             shares and a contingent deferred sales charge
                             payable upon certain redemptions within one year of
                             purchase. Class C shares do not covert into another
                             class. Class I shares (none sold through March 31,
                             1998) are offered to a limited group of investors,
                             are not subject to initial or contingent deferred
                             sales charges and have lower ongoing expenses than
                             other classes. Differences in class expenses will
                             result in the payment of different per share income
                             dividends by class. All shares of the Fund have
                             equal rights with respect to voting, dividends and
                             assets, subject to class specific preferences.

2    SIGNIFICANT
     ACCOUNTING POLICIES     INVESTMENT VALUATION. Investments are stated at
                             value. Fixed income securities are valued by using
                             market quotations, or independent pricing services
                             that use prices provided by market makers or
                             estimates of market values obtained from yield data
                             relating to instruments or securities with similar
                             characteristics. Financial futures and options are
                             valued at the settlement price established each day
                             by the board of trade or exchange on which they are
                             traded. Over-the-counter traded fixed income
                             options are valued based upon prices provided by
                             market makers. Other securities and assets are
                             valued at fair value as determined in good faith by
                             the Board of Trustees.
 
                             INVESTMENT TRANSACTIONS AND INVESTMENT INCOME.
                             Investment transactions are accounted for on the
                             trade date (date the order to buy or sell is
                             executed). Interest income is recorded on the
                             accrual basis and includes discount amortization on
                             all fixed income securities and premium
                             amortization on mortgage-backed securities.
                             Realized gains and losses from investment
                             transactions are reported on an identified cost
                             basis.
 
                             The Fund may purchase securities with delivery or
                             payment to occur at a later date. At the time the
                             Fund enters into a commitment to purchase a
                             security, the transaction is recorded and the value
                             of the security is reflected in the net asset
                             value. The value of the security may vary with
                             market fluctuations. No interest accrues to the
                             Fund until payment takes place. At the time the
                             Fund enters into this type of transaction it is
                             required to segregate cash or other liquid assets
                             equal to the value of the securities purchased. At
                             March 31, 1998, the Fund had $18,323,000 in
                             purchase commitments outstanding (11% of net
                             assets) with a corresponding amount of assets
                             segregated.
 
                             FUND SHARE VALUATION. Fund shares are sold and
                             redeemed on a continuous basis at net asset value
                             (plus an initial sales charge on most sales of
                             Class A shares). Proceeds payable on redemption of
                             Class B and Class C shares will be reduced by the
                             amount of any applicable contingent deferred sales
                             charge. On each day the New York Stock Exchange is
                             open for trading, the net asset value per share is
                             determined as of the earlier of 3:00 p.m. Chicago
                             time or the close of the Exchange. The net asset
                             value per share is determined separately for each
                             class

                             that class by the number of shares of the class
                             outstanding.
 
                             FEDERAL INCOME TAXES. The Fund has complied with
                             the special provisions of the Internal Revenue Code
                             available to investment companies for the six
                             months ended March 31, 1998. The accumulated net
                             realized loss on sales of investments for federal
                             income tax purposes at March 31, 1998, amounting to
                             approximately $22,519,000, is available to offset
                             future taxable gains. If not applied, the loss
                             carryover expires during the period 2002 through
                             2006.
 
                             DIVIDENDS TO SHAREHOLDERS. The Fund declares and
                             pays dividends of net investment income monthly and
                             any net realized capital gains annually, which are
                             recorded on the ex-dividend date. Dividends are
                             determined in accordance with income tax principles
                             which may treat certain transactions differently
                             from generally accepted accounting principles.
 
                             EQUALIZATION ACCOUNTING. A portion of proceeds from
                             sales and cost of redemptions of Fund shares is
                             credited or charged to undistributed net investment
                             income so that income per share available for
                             distribution is not affected by sales or
                             redemptions of shares.

3    TRANSACTIONS WITH
     AFFILIATES              INVESTMENT MANAGER COMBINATION. Effective December
                             31, 1997, Zurich Insurance Company, the parent of
                             Zurich Kemper Investments, Inc. (ZKI), acquired a
                             majority interest in Scudder, Stevens & Clark, Inc.
                             (Scudder), another major investment manager. As a
                             result of this transaction, the operations of ZKI
                             were combined with Scudder to form a new global
                             investment organization named Scudder Kemper
                             Investments, Inc. (Scudder Kemper). The transaction
                             resulted in the termination of the Fund's
                             investment management agreement with ZKI, however,
                             a new investment management agreement between the
                             Fund and Scudder Kemper was approved by the Fund's
                             Board of Trustees and by the Fund's shareholders.
                             The new management agreement, which was effective
                             December 31, 1997, is the same in all material
                             respects as the previous management agreement,
                             except that Scudder Kemper is the new investment
                             adviser to the Fund. In addition, the names of the
                             Fund's principal underwriter and shareholder
                             service agent were changed to Kemper Distributors,
                             Inc. (KDI) and Kemper Service Company (KSvC),
                             respectively.
 
                             MANAGEMENT AGREEMENT. The Fund has a management
                             agreement with Scudder Kemper, and pays a
                             management fee at an annual rate of .55% of the
                             first $250 million of average daily net assets
                             declining to .40% of average daily net assets in
                             excess of $12.5 billion. The Fund incurred a
                             management fee of $470,000 for the six months ended
                             March 31, 1998.

REPORT OF INDEPENDENT AUDITORS

THE BOARD OF TRUSTEES AND SHAREHOLDERS
KEMPER SHORT-INTERMEDIATE GOVERNMENT FUND
 
  We have audited the accompanying statement of assets and liabilities,
including the portfolio of investments, of Kemper Short-Intermediate Government
Fund, a series of Kemper Portfolios, as of September 30, 1997, the related
statements of operations for the year then ended and changes in net assets for
each of the two years in the period then ended and the financial highlights for
each of the fiscal periods since 1993. These financial statements and financial
highlights are the responsibility of the Fund's management. Our responsibility
is to express an opinion on these financial statements and financial highlights
based on our audits.
 
  We conducted our audits in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements and financial
highlights are free of material misstatement. An audit includes examining, on a
test basis, evidence supporting the amounts and disclosures in the financial
statements. Our procedures included confirmation of investments owned as of
September 30, 1997, by correspondence with the custodian. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audits provide a reasonable basis for our opinion.
 
  In our opinion, the financial statements and financial highlights referred to
above present fairly, in all material respects, the financial position of Kemper
Short-Intermediate Government Fund at September 30, 1997, the results of its
operations for the year then ended, the changes in its net assets for each of
the two years in the period then ended, and the financial highlights for the
fiscal periods since 1993, in conformity with generally accepted accounting
principles.

1    DESCRIPTION OF THE
     FUND                    Kemper Short-Intermediate Government Fund is a
                             separate series of Kemper Portfolios, an open-end
                             management investment company organized as a
                             business trust under the laws of Massachusetts. The
                             Fund offers four classes of shares. Class A shares
                             are sold to investors subject to an initial sales
                             charge. Class B shares are sold without an initial
                             sales charge but are subject to higher ongoing
                             expenses than Class A shares and a contingent
                             deferred sales charge payable upon certain
                             redemptions. Class B shares automatically convert
                             to Class A shares six years after issuance. Class C
                             shares are sold without an initial sales charge but
                             are subject to higher ongoing expenses than Class A
                             shares and a contingent deferred sales charge
                             payable upon certain redemptions within one year of
                             purchase. Class C shares do not covert into another
                             class. Class I shares (none sold through September
                             30, 1997) are offered to a limited group of
                             investors, are not subject to initial or contingent
                             deferred sales charges and have lower ongoing
                             expenses than other classes. Differences in class
                             expenses will result in the payment of different
                             per share income dividends by class. All shares of
                             the Fund have equal rights with respect to voting,
                             dividends and assets, subject to class specific
                             preferences.

2    SIGNIFICANT
     ACCOUNTING POLICIES     INVESTMENT VALUATION. Investments are stated at
                             value. Fixed income securities are valued by using
                             market quotations, or independent pricing services
                             that use prices provided by market makers or
                             estimates of market values obtained from yield data
                             relating to instruments or securities with similar
                             characteristics. Financial futures and options are
                             valued at the settlement price established each day
                             by the board of trade or exchange on which they are
                             traded. Over-the-counter traded fixed income
                             options are valued based upon prices provided by
                             market makers. Other securities and assets are
                             valued at fair value as determined in good faith by
                             the Board of Trustees.
 
                             INVESTMENT TRANSACTIONS AND INVESTMENT INCOME.
                             Investment transactions are accounted for on the
                             trade date (date the order to buy or sell is
                             executed). Interest income is recorded on the
                             accrual basis and includes discount amortization on
                             all fixed income securities and premium
                             amortization on mortgage-backed securities.
                             Realized gains and losses from investment
                             transactions are reported on an identified cost
                             basis.
 
                             The Fund may purchase securities with delivery or
                             payment to occur at a later date. At the time the
                             Fund enters into a commitment to purchase a
                             security, the transaction is recorded and the value
                             of the security is reflected in the net asset
                             value. The value of the security may vary with
                             market fluctuations. No interest accrues to the
                             Fund until payment takes place. At the time the
                             Fund enters into this type of transaction it is
                             required to segregate cash or other liquid assets
                             equal to the value of the securities purchased. At
                             September 30, 1997, the Fund had $15,591,000 in
                             purchase commitments outstanding (9% of net assets)
                             with a corresponding amount of assets segregated.
 
                             FUND SHARE VALUATION. Fund shares are sold and
                             redeemed on a continuous basis at net asset value
                             (plus an initial sales charge on most sales of
                             Class A shares). Proceeds payable on redemption of
                             Class B and Class C shares will be reduced by the
                             amount of any applicable contingent deferred sales
                             charge. On each day the New York Stock Exchange is
                             open for trading, the net asset value per share is
                             determined as of the earlier of 3:00 p.m. Chicago
                             time or the close of the Exchange. The net asset
                             value per share is determined separately for each
                             class

                             FEDERAL INCOME TAXES. The Fund has complied with
                             the special provisions of the Internal Revenue Code
                             available to investment companies and therefore no
                             federal income tax provision is required. The
                             accumulated net realized loss on sales of
                             investments for federal income tax purposes at
                             September 30, 1997, amounting to approximately
                             $22,500,000, is available to offset future taxable
                             gains. If not applied, the loss carryover expires
                             during the period 2002 through 2006.
 
                             DIVIDENDS TO SHAREHOLDERS. The Fund declares and
                             pays dividends of net investment income monthly and
                             any net realized capital gains annually, which are
                             recorded on the ex-dividend date. Dividends are
                             determined in accordance with income tax principles
                             which may treat certain transactions differently
                             from generally accepted accounting principles.
 
                             EQUALIZATION ACCOUNTING. A portion of proceeds from
                             sales and cost of redemptions of Fund shares is
                             credited or charged to undistributed net investment
                             income so that income per share available for
                             distribution is not affected by sales or
                             redemptions of shares.

6    FINANCIAL FUTURES
     CONTRACTS               The Fund has entered into exchange traded financial
                             futures contracts in order to help protect itself
                             from anticipated market conditions and, as such,
                             bears the risk that arises from entering into these
                             contracts.
 
                             At the time the Fund enters into a futures
                             contract, it is required to make a margin deposit
                             with its custodian. Subsequently, gain or loss is
                             recognized and payments are made on a daily basis
                             between the Fund and its broker as the market value
                             of the futures contract fluctuates. At September
                             30, 1997, the market value of assets pledged by the
                             Fund to cover margin requirements for open futures
                             positions was $102,000. The Fund also had liquid
                             securities in its portfolio in excess of the face
                             amount of the following short futures position open
                             at September 30, 1997:

ITEM 15. INDEMNIFICATION
 
Article VIII of the Registrant's Agreement and Declaration of Trust (Exhibit 1
hereto, which is incorporated herein by reference) provides in effect that the
Registrant will indemnify its officers and trustees under certain circumstances.
However, in accordance with Section 17(h) and 17(i) of the Investment Company
Act of 1940 and its own terms, said Article of the Agreement and Declaration of
Trust does not protect any person against any liability to the Registrant or its
shareholders to which he would otherwise be subject by reason of willful
misfeasance, bad faith, gross negligence, or reckless disregard of the duties
involved in the conduct of his office.
 
Insofar as indemnification for liabilities arising under the Securities Act of
1933 may be permitted to trustees, officers, and controlling persons of the
Registrant pursuant to the foregoing provisions, or otherwise, the Registrant
has been advised that, in the opinion of the Securities and Exchange Commission,
such indemnification is against public policy as expressed in the Act and is,
therefore, 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 a trustee, officer, or controlling person of the Registrant in the
successful defense of any action, suit, or proceeding) is asserted by such
trustee, officer, or controlling person in connection with the securities 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 as to whether such indemnification by it is against
public policy as expressed in the Act and will be governed by the final
adjudication of such issue.
 
On June 26, 1997, Zurich Insurance Company ("Zurich"), ZKI Holding Corp.
("ZKIH"), Zurich Kemper Investments, Inc. ("ZKI"), Scudder, Stevens & Clark,
Inc. ("Scudder") and the representatives of the beneficial owners of the capital
stock of Scudder ("Scudder Representatives") entered into a transaction
agreement ("Transaction Agreement") pursuant to which Zurich will become the
majority stockholder in Scudder with an approximately 70% interest, and ZKI will
become a wholly-owned subsidiary of, or be combined with,
Scudder-("Transaction"). In connection with the trustees' evaluation of the
Transaction, Zurich agreed to indemnify the Registrant and the trustees who were
not interested persons of ZKI or Scudder (the "Independent Trustees") for and
against any liability and expenses based upon any action or omission by the
Independent Trustees in connection with their consideration of and action with
respect to the Transaction. In addition, Scudder has agreed to indemnify each
Fund and the Independent Trustees for and against any liability and expenses
based upon any misstatements or omissions by Scudder to the Independent Trustees
in connection with their consideration of the Transaction.
