     per share, of ZIP (the "ZIP Common Stock") issued and outstanding
     immediately prior to the Effective Time shall be converted into and become
     one share of Common Stock, par value $5.00 per share, of the Surviving
     Corporation, which will be duly authorized, validly issued, fully paid and
     nonassessable.
 
          (b) Cancellation of Treasury Stock.  Each share of Common Stock that
     is owned by the Company or by any subsidiary of the Company (other than
     shares held in trust accounts, managed accounts, custodial accounts and the
     like, shares that are beneficially owned by third parties and shares held
     in the ordinary course of business by subsidiaries of the Company that are
     insurance companies or broker-dealers) shall automatically be cancelled and
     retired and shall cease to exist, and no cash or other consideration shall

     outstanding immediately prior to the Effective Time (other than shares to
     be cancelled in accordance with Section 2.1(b) and other than Dissenting

<PAGE>   8

     Convertible Preferred Stock, Series C Cumulative Preferred Stock, Series D
     Index Exchangeable Preferred Stock and Series E Cumulative Convertible
     Preferred Stock, respectively, of the Surviving Corporation. The Series A
     Preferred Stock, Series C Preferred Stock, Series D Preferred Stock and
     Series E Preferred Stock are referred to collectively as the "Company
     Preferred Stock."
 
          (e) Dissenting Shares.  (i) Notwithstanding anything in this Agreement
     to the contrary, shares of Common Stock issued and outstanding immediately
     prior to the Effective Time held by a holder (if any) who has the right to
     demand, and who properly demands, an appraisal of such shares in accordance
     with Section 262 of the DGCL (or any successor provision) ("Dissenting
     Common Shares") shall not be converted into a right to receive Merger
     Consideration unless such holder fails to perfect, withdraws or otherwise
     loses such holder's right to such appraisal, if any. If, after the
     Effective Time, such holder fails to perfect, withdraws or loses such right
     to appraisal, each such share of such holder shall be treated as a share
     that had been converted at the Effective Time into the right to receive
     Merger Consideration in accordance with this Section 2.1. Prior to the
     Effective Time, the Company shall give prompt notice to ZIP of any demands
     received by the Company for appraisal of shares of Common Stock, and ZIP
     shall have the right to participate in and direct all negotiations and
     proceedings with respect to such demands. Prior to the Effective Time, the
     Company shall not, except with the prior written consent of ZIP, make any
     payment with respect to, or settle or offer to settle, any such demands.
 
          (ii) Notwithstanding anything in this Agreement to the contrary,
     shares of Company Preferred Stock issued and outstanding immediately prior
     to the Effective Time held by a holder (if any) who has the right to
     demand, and who properly demands, an appraisal of such shares in accordance
     with Section 262 of the DGCL ("Dissenting Preferred Shares") shall not be
     deemed to remain outstanding as of the Effective Time, in accordance with
     this Section 2.1, unless such holder fails to perfect, withdraws or
     otherwise loses such holder's right to such appraisal, if any. If, after
     the Effective Time, such holder fails to perfect, withdraws or loses any
     such right to appraisal, such shares shall be treated as if they had
     remained outstanding as of the Effective Time, in accordance with this
     Section 2.1. Prior to the Effective Time, the Company shall give prompt
     notice to ZIP of any demands received by the Company for appraisal of
     shares of Company Preferred Stock, and ZIP shall have the right to
     participate in and direct all negotiations and proceedings with respect to
     such demands. Prior to the Effective Time, the Company shall not, except
     with the prior written consent of ZIP, make any payment with respect to, or
     settle or offer to settle, any such demands.
 
          (f) Cancellation and Retirement of Common Stock.  As of the Effective
     Time, all certificates representing shares of Common Stock (other than
     certificates representing shares cancelled in accordance with Section
     2.1(b) and Dissenting Common Shares) issued and outstanding immediately
     prior to the Effective Time, shall no longer be deemed outstanding, and
     each holder of a certificate representing any such shares of Common Stock
     shall cease to have any rights with respect thereto, except the right to
     receive the Merger Consideration upon surrender of such certificate in
     accordance with Section 2.3. At the Effective Time, all certificates
     representing Dissenting Common Shares or Dissenting Preferred Shares issued
     and outstanding immediately prior to the Effective Time shall no longer be
     deemed outstanding and shall cease to have any rights with respect thereto
     except the rights referred to in Section 2.1(e).
 
     SECTION 2.2 Stock Options and Phantom Stock Units.  (a) As of the date
hereof, the unexercisable portion of each outstanding option (other than each
option cancelled as a result of the exercise of the related Phantom Stock Option
(as defined below)) to purchase shares of Common Stock (a "Company Stock
Option") issued under the Kemper Corporation 1982 Incentive Stock Option Plan,
the Kemper Corporation 1985 Amended Stock Option Plan, the Kemper Corporation
1990 Stock Option Plan and the Kemper Corporation Non-Management Directors Stock
Option Plan (collectively, the "Company Stock Option Plans") and each
outstanding Option Associated Phantom
 
                                        3
<PAGE>   9
 
Stock Award (a "Phantom Stock Option") issued (other than each Phantom Stock
Option cancelled in accordance with its terms) under the Kemper Corporation 1995
Executive Incentive Plan (the "1995 Plan") shall become immediately exercisable
in full, subject to all expiration, lapse and other terms and conditions
thereof. Immediately prior to the Effective Time, the unexercisable portion of
each outstanding phantom stock unit issued under the 1995 Plan (each a "Phantom
Stock Unit" and collectively, with the Phantom Stock Options, the "Phantom Stock
Rights") shall become immediately exercisable in full, subject to all
expiration, lapse and other terms and conditions thereof.
 
     (b) Each Company Stock Option (and any rights thereunder) and Phantom Stock
Right (and any rights thereunder) outstanding immediately prior to the Effective
Time shall be cancelled immediately prior to the Effective Time in exchange for
the right to receive an amount in cash equal to the product of (A) the number of
shares of Common Stock subject to such Company Stock Option or such Phantom
Stock Right immediately prior to the Effective Time and (B) the excess, if any,
of (1) the Merger Consideration per share of Common Stock over (2) the per share
exercise price or appreciation base ($0 in the case of the Phantom Stock Units
and $45.125 in the case of the Phantom Stock Options), as the case may be, of
such Company Stock Option or such Phantom Stock Right, to be delivered within
ten business days (subject to receipt by ZIP of an executed consent to the
cancellation of all Company Stock Options and Phantom Stock Rights held by such
Person and to the Anti-dilution Actions (as defined herein)) after the Effective
Time from the Paying Agent (as defined herein) out of the Payment Fund (as
defined herein) subject to the terms and conditions of Section 2.3; provided,
however, that, in no event, shall a Person who holds a Company Stock Option and
a related Phantom Stock Right be entitled to payment in respect of both such
Company Stock Option and related Phantom Stock Right.
 
     SECTION 2.3 Exchange of Certificates.  (a) Paying Agent.  Prior to the
Effective Time, ZIP shall designate a bank or trust company reasonably
satisfactory to the Company to act as paying agent in the Merger (the "Paying
Agent") for the purpose of effecting the exchange of certificates previously
representing shares of Common Stock for the Merger Consideration and paying
amounts due to the holders of the Company Stock Options and the Phantom Stock
Rights. Immediately prior to the Effective Time, for the benefit of the holders
of shares of Common Stock, the holders of shares of Series A Preferred Stock and
Series E Preferred Stock (together, the "Convertible Preferred Stock") and the
holders of the Company Stock Options and the Phantom Stock Rights, ZIP shall
deposit, or cause to be deposited, with or for the account of the Exchange
Agent, cash in an aggregate amount sufficient to pay the aggregate Merger
Consideration (assuming the full conversion of all outstanding shares of Series
A Preferred Stock and Series E Preferred Stock prior to the Effective Time) and
the aggregate cash consideration payable to the holders of the Company Stock
Options and Phantom Stock Rights under Section 2.2.
 
     (b) Exchange Procedures.  (i) Promptly after the Effective Time (but in no
event more than five days thereafter), the Surviving Corporation shall require
the Paying Agent to mail to each holder of record of certificates which
immediately prior to the Effective Time (other than the holders referred to in
Section 2.1(b) or (e)) represented shares of Common Stock which were converted
into the right to receive the Merger Consideration pursuant to Section 2.1, (i)
a letter of transmittal (which shall specify that delivery shall be effected,
and risk of loss and title to the certificates shall pass, only upon delivery of
such certificates to the Exchange Agent and shall be in such form and have such
other provisions as the Surviving Corporation may reasonably specify) and (ii)
instructions for use in effecting the surrender in exchange for the Merger
Consideration to which such holder shall be entitled therefor pursuant to
Section 2.1. Upon surrender to the Paying Agent of such certificate, together
with such letter of transmittal, duly executed, and such other documents as
reasonably may be required by the Paying Agent, and acceptance thereof by the
Paying Agent, the holder of such certificate shall be entitled to receive in
exchange therefore the amount of Merger Consideration that such holder has the
right to receive pursuant to Section 2.1(c) of this Agreement, and such
certificate so surrendered shall forthwith be cancelled. The Paying Agent shall
accept such certificates upon compliance with such reasonable terms and
conditions as the Paying Agent may impose to effect an
 
                                        4
<PAGE>   10
 
orderly exchange thereof in accordance with normal exchange practices. If the
Merger Consideration (or any portion thereof) to be paid in the Merger is to be
delivered to any person other than the person in whose name the certificate
previously representing shares of Common Stock surrendered in exchange therefor
is registered, it shall be a condition to such exchange that the certificate so
surrendered shall be properly endorsed or otherwise be in proper form for
transfer and that the person requesting such exchange shall pay to the Paying
Agent any transfer or other taxes required by reason of the payment of such
Merger Consideration to a person other than the registered holder of the
certificate surrendered, or shall establish to the satisfaction of the Paying
Agent that such tax has been paid or is not applicable. After the Effective
Time, there shall be no further transfer on the records of the Company or its
transfer agent of certificates previously representing shares of Common Stock
and if such certificates are presented to the Company for transfer, they shall
be cancelled against delivery of the Merger Consideration as hereinabove
provided. Until surrendered as contemplated by this Section 2.3(b), each
certificate which immediately prior to the Effective Time represented shares of
Common Stock (other than certificates representing shares cancelled in
accordance with Section 2.1(b) and Dissenting Common Shares), shall be deemed at
any time after the Effective Time to represent only the right to receive upon
such surrender the Merger Consideration, without any interest thereon, as
contemplated by Section 2.1. No interest will be paid or will accrue on the
Merger Consideration.
 
     (ii) Promptly after the Effective Time (but in no event later than five
business days thereafter), the Surviving Corporation shall, if necessary, cause
the Paying Agent to mail to the holders of Company Stock Options and Phantom
Stock Rights a written notice stating that the Surviving Corporation has
deposited with the Paying Agent the aggregate cash consideration payable to the
holders of such options and rights under Section 2.2 and such consideration
shall be delivered to such holder upon receipt by the Surviving Corporation or
ZIP of an executed consent to the cancellation of such options or rights as
described in Section 2.2.
 
     (c) No Further Ownership Rights in Common Stock.  The Merger Consideration
paid upon the surrender for exchange of certificates previously representing
shares of Common Stock in accordance with the terms of this Article II shall be
deemed to have been issued and paid in full satisfaction of all rights
pertaining to the shares of Common Stock previously represented by such
certificates, subject, however, to the Surviving Corporation's obligation (if
any) to pay any dividends or make any other distributions with a record date
prior to the Effective Time which may have been declared by the Company on such
shares of Common Stock in accordance with the terms of this Agreement or prior
to the date of this Agreement and which remain unpaid at the Effective Time.
 
     (d) Termination of Payment Fund.  In the event that a holder of Dissenting
Common Shares or a holder of Dissenting Preferred Shares (representing
Convertible Preferred Stock) perfects his right to payment for such Dissenting
Common Shares or Dissenting Preferred Shares pursuant to Sections 262 of the
DGCL (or any successor provision), the Paying Agent shall release to the
Surviving Corporation cash equal to the Merger Consideration (or the cash
payable upon conversion of the Convertible Preferred Stock) that would have been
paid to such holder under Section 2.1 if such shares were not Dissenting Common
Shares or Dissenting Preferred Shares. Any portion of the Payment Fund which
remains undistributed to the holders of the certificates representing shares of
Common Stock or the Company Stock Options or Phantom Stock Rights for 120 days
after the Effective Time shall be delivered to the Surviving Corporation, upon
demand, and any holders of shares of Common Stock or Company Stock Options or
Phantom Stock Rights who have not theretofore complied with this Article II
shall thereafter look only to the Surviving Corporation and only as general
creditors thereof for payment of their claim for any Merger Consideration (or,
with respect to Company Stock Options and Phantom Stock Rights, consideration
payable pursuant to Section 2.2).
 
     (e) No Liability.  None of Zurich, Insurance Partners, the Surviving
Corporation or the Paying Agent shall be liable to any person in respect of any
cash payable from the Payment Fund delivered to a Governmental Entity (as
defined in Section 3.1(d)) pursuant to any applicable abandoned property,
escheat or similar law. If any certificates which represented shares of Common
Stock shall
 
                                        5
<PAGE>   11
 
not have been surrendered or the former holders of any Company Stock Options or
Phantom Stock Rights shall not have received amounts payable under Section 2.2
prior to five years after the Effective Time (or immediately prior to such
earlier date on which any Merger Consideration in respect of such certificate,
option or right would otherwise escheat to or become the property of any
Governmental Entity), any such cash payable in respect of such certificate,
option or right shall, to the extent permitted by applicable law, become the
property of the Surviving Corporation, free and clear of all claims or interest
of any person previously entitled thereto.
 
     (f) Investment of Payment Fund.  The Paying Agent shall invest the Payment
Fund, as directed by ZIP (and after the Effective Time, the Surviving
Corporation), and any net earnings with respect thereto shall be paid to the
Surviving Corporation as and when requested by the Surviving Corporation;
provided, that, any such investment or any such payment of earnings shall not
delay the receipt by holders of shares of Common Stock of the Merger
Consideration or the receipt by holders of shares of Convertible Preferred Stock
of the amounts to which they are entitled with respect to any shares of
Convertible Preferred Stock theretofore converted in accordance with the terms
thereof or receipt by the holders of Company Stock Options or Phantom Stock
Rights of the consideration payable pursuant to Section 2.2 or otherwise impair
such holders' respective rights hereunder. In the event the Payment Fund shall
realize a loss on any such investment, the Surviving Corporation shall promptly
thereafter deposit in such Payment Fund cash in an amount sufficient to enable
such Payment Fund to satisfy all remaining obligations originally contemplated
to be paid out of such Payment Fund.
 
     (g) Conversion of the Convertible Preferred Stock.  Until the Payment Fund
is terminated pursuant to Section 2.3(d), the Surviving Corporation shall, and
shall require the Paying Agent to, make the Payment Fund available for the
purpose of paying any amounts due with respect to any shares of Convertible
Preferred Stock theretofore converted in accordance with the terms thereof.
 
                                  ARTICLE III
 
                         REPRESENTATIONS AND WARRANTIES

     now being conducted. Each of the Company and each Significant Subsidiary of
     the Company is duly qualified or licensed to do business and is in good
     standing in each jurisdiction in which the nature of its business or the
     ownership or leasing of its properties makes such qualification or
     licensing necessary, other than in such jurisdictions where the failure to
     be so qualified or licensed (individually or in the aggregate) would not
     have a Material Adverse Effect with respect to the Company. The Company has
     delivered to Zurich and Insurance Partners complete and correct copies of
     its Charter and By-laws, as amended to the date of this Agreement. Set
     forth in Section 3.1(a) of the Disclosure Schedule are the names of all
     Real Estate Subsidiaries (with the Excluded Real Estate Subsidiaries noted
     by an asterisk). For purposes of this Agreement, a "Significant Subsidiary"
     of the Company means each of Kemper Securities Holdings, Inc. ("KSH"),
     Kemper Securities, Inc. ("KSI"), Federal Kemper Life Assurance Company
     ("FKLA"), Kemper Financial Companies, Inc. ("KFC"), Kemper Financial
     Services, Inc. ("KFS"), Kemper Investors Life Insurance Company ("KILICO"
     and, together with FKLA, the "Insurance Companies") and any other
     subsidiary of the Company that would constitute a Significant Subsidiary
     within the meaning of Rule 1-02 of Regulation S-X of the Securities and
     Exchange Commission (the "SEC"); provided, however, that KSH, KSI and
     Kemper Clearing Corp. shall be Significant Subsidiaries only so long as
     they are subsidiaries of the Company.

     stock or other equity securities of the Company were issued, reserved for

     and clear of all pledges, claims, liens, charges, encumbrances and security
     interests of any kind or nature whatsoever (collectively, "Liens"). Except
     as set forth above or in Section 3.1(b) of the Disclosure Schedule and
     except as expressly set forth in this Section 3.1(b) with respect to KFC,
     neither the Company nor any Significant Subsidiary of the Company has any
     outstanding option, warrant, subscription or other right, agreement or
     commitment which either (i) obligates the Company or any Significant
     Subsidiary of the Company to issue, sell or transfer, repurchase, redeem or
     otherwise acquire or vote any shares of the capital stock of the Company or
     any Significant Subsidiary of the Company or (ii) restricts the transfer of
     Common Stock. Grants of 116,900 and 95,100 restricted shares of Common
     Stock under the Kemper Corporation 1993 Senior Executive Long-Term
     Incentive Plan by the Board of Directors on May 12, 1993 and April 11,
     1994, respectively, were not approved by the stockholders of the Company
     and such grants expired by their terms and currently do not exist. The
     authorized capital stock of KFC consists of 150,000,000 shares of common
     stock, par value $.10 per share, which shares are divided into 135,000,000
     shares of Class A Common Stock ("KFC Class A Common Stock") and 15,000,000
     shares of Class B Common Stock ("KFC Class B Common Stock"). At the close
     of business on March 31, 1995, (i) 43,268,038 shares of KFC Class A Common
     Stock and 5,831 shares of KFC Class B Common Stock were issued and
     outstanding and, in the case of KFC Class B Common Stock, not subject as of
     such date to mandatory redemption, (ii) 160,595 shares of KFC Class B
     Common Stock were reserved for issuance pursuant to outstanding KFC
     employee stock options (the "KFC Stock Options"), (iii) no shares of
     Preferred Stock of KFC were outstanding and (iv) approximately $32.7
     million aggregate principal amount of KFC's floating rate convertible
     subordinated debentures (the "KFC Debentures") were outstanding, which are
     convertible into an aggregate of 1,153,959 shares of KFC Class B Common
     Stock. Except as set forth in Section 3.1(b) of the Disclosure Schedule,
     since April 1, 1995, KFC has not issued any securities, stock options or
     Phantom Stock Rights other than shares of KFC Class B Common Stock issued
     pursuant to the exercise of KFC Stock Options outstanding on March 31, 1995
     and pursuant to the conversion of KFC Debentures outstanding on March 31,
     1995. All outstanding KFC Debentures are currently redeemable at the option
     of KFC. As determined at December 31, 1994 (after taking into account the
     sale of approximately 55% of the common stock (the "Newco Common Stock") of
     a newly formed company ("Newco") that will be the owner of all the
     outstanding shares of KSH to an employee stock ownership plan (the "ESOP"),
     the sale of approximately 44% of the Newco Common Stock by KFC to the
     Company as payment for intercompany indebtedness, the issuance of
     approximately 1% of the Newco non-voting common stock to the management of
     KSI and the distribution of approximately 44% of the Newco Common Stock by
     the Company to its stockholders pursuant to the terms and conditions set
     forth in Exhibit I to the Disclosure Schedule (collectively, the "ESOP
     Sale"), the merger of KFS into KFS Acquisition Corp. (the "KFS Sale")
     pursuant to the Agreement and Plan of Merger, dated as of the date hereof
     (as amended from time to time, the "KFS Agreement"), between the Company,
     KFS, KFC, Zurich and KFS Acquisition Corp. and the other transactions
     contemplated by this Agreement) in accordance with the terms of KFC's
     Fourth Restated Certificate of Incorporation (the "KFC Charter"), the
     Formula Purchase Price Per Share (as defined in the KFC Charter) for
     repurchases by KFC of shares of the KFC Class B Common Stock would have
     been less than $20 per share. At the Effective Time, all KFC Debentures and
     shares of KFC Class B Common Stock outstanding will be mandatorily
     redeemable by KFC, and all KFC Stock Options will become subject to
     expiration in accordance with their terms, unless ZIP exercises its right
     under Section 6.2(d) to delay the KFS Sale until after the Effective Time
     and provided that Invest Financial Corporation is at least a 50% owned
     subsidiary of KFS at the time of the KFS Sale. After the Effective Time,
     the holders of the KFC Debentures, the KFC Class B Common Stock and the KFC
     Stock Options shall have no rights other than the right to receive payment
     therefor (except, in the case of holders of KFC Stock Options, the right to
     receive shares of KFC Class B Common Stock upon the exercise thereof) in
     accordance with the terms of such securities, unless ZIP exercises its
     right under Section 6.2(d) to delay the KFS Sale until after the Effective
     Time and provided that Invest Financial Corporation is at least a 50% owned
     subsidiary of KFS at the time of

     the KFS Sale. The exercise prices for all KFC Stock Options and the
     conversion prices for all KFC Debentures are $20 or more per share of KFC
     Class B Common Stock and in each case, are set forth in Section 3.1(b) of
     the Disclosure Schedule. As of the date hereof, each share of outstanding
     Series A Preferred Stock is convertible into 2.24718 shares of Common Stock
     and each share of outstanding Series E Preferred Stock is convertible into
     1.0339 shares of Common Stock. Except for the adjustment required as a
     result of the ESOP Sale, no event has occurred that would require the
     conversion prices for the Series A Preferred Stock and the Series E
     Preferred Stock to be adjusted.

     liabilities have been communicated to ZIP, and all such liabilities have
     been allocated in accordance with generally accepted accounting principles
     on the books of the Company and the Company's subsidiaries to which such

     Schedule, with respect to those Benefit Plans that are "welfare plans" (as
     defined in section 3(1) of ERISA) there are no reserves, assets, surpluses

     respect to the Company.
 
          (vi) Except as set forth in Section 3.1(i)(vi) of the Disclosure

     payment or vesting of, or increase the amount of, compensation due to any
     individual; except in the case where any of the foregoing, either
     individually or in the aggregate, would not have a Material Adverse Effect
     with respect to the Company.
 
          (vii) Except as disclosed in Section 3.1(i)(vii) of the Disclosure
     Schedule or where the existence of any of the following, either

          (ix) Within the five year period ending on the date of this Agreement,
     neither the Company nor any member of its "controlled group" (within the
     meaning of Section 4069 of ERISA) has engaged in any transaction which
     could result in liability to any of the parties to this Agreement, or to
     any other members of their respective controlled groups (as above so
     defined), pursuant to Section 4069 of ERISA or otherwise with respect to
     any Benefit Plan maintained by the Company or any other member of its
     controlled group (as above so defined) during such five-year period, but
     not so maintained as of the date of this Agreement, except where the
     existence of such a liability would not have a Material Adverse Effect with
     respect to the Company.
 
          (j) Litigation.  As of the date of this Agreement, except as disclosed
     in Section 3.1(j) of the Disclosure Schedule or the Filed SEC Documents,
     there is no suit, action, proceeding, arbitration or investigation pending
     or, to the knowledge of the Company, threatened against the Company or any
     subsidiary of the Company that, individually or in the aggregate with any
     other such suits, actions, proceedings, arbitrations or investigations,
     could reasonably be expected to have a Material Adverse Effect with respect
     to the Company, nor is there any judgment, decree, injunction, rule or
     order of any Governmental Entity or arbitrator outstanding against the
     Company or any subsidiary of the Company that, individually or in the
     aggregate, could reasonably be expected to have a Material Adverse Effect
     with respect to the Company.
 
          (k) Taxes.  (i) Except as set forth in Section 3.1(k)(i) of the
     Disclosure Schedule, each of the Company, its subsidiaries (other than the
     Excluded Real Estate Subsidiaries) and, to the knowledge of the Company,
     the Excluded Real Estate Subsidiaries has filed all tax returns and reports
     required to be filed by it or requests for extensions to file such returns
     or reports have been timely filed, granted and have not expired. All tax
     returns filed by the Company and each of its subsidiaries are complete and
     accurate except to the extent that such failure to be complete and accurate
     would not have a Material Adverse Effect with respect to the Company. The
     Company and each of its subsidiaries (other than the Excluded Real Estate
     Subsidiaries) and, to the knowledge of the Company, the Excluded Real
     Estate Subsidiaries has paid (or the Company has paid on the subsidiaries'
     behalf) all taxes shown as due on such returns, and the most recent
     financial statements contained in the Filed SEC Documents reflect, in
     management's best judgment, an adequate reserve for all taxes payable by
     the Company and its subsidiaries (other than the Excluded Real Estate
     Subsidiaries) and, to the knowledge of the Company, the Excluded Real
     Estate Subsidiaries for all taxable periods and portions thereof accrued
     through the date of such financial statements.
 
          (ii) Except as set forth on Section 3.1(k)(ii) of the Disclosure
     Schedule, no deficiencies for any taxes have been proposed, asserted,
     assessed or threatened against the Company, any of its subsidiaries (other
     than the Excluded Real Estate Subsidiaries) or, to the knowledge of the
     Company, any of the Excluded Real Estate Subsidiaries that are not
     adequately reserved for and no requests for waivers of the time to assess
     any Federal or Illinois taxes or any other material taxes have been granted
     or are pending. The Federal and Illinois income tax returns of the Company
     and each of its subsidiaries consolidated in such returns have been
     examined by and settled with the United States Internal Revenue Service or
     the Illinois Department of Revenue, as the case may be, or the statute of
     limitations on assessment or collection of any Federal or Illinois income
     taxes due from the Company or any of such subsidiaries has expired, for all
     taxable years of the Company or any of such subsidiaries through the
     taxable year ended December 31, (a) 1986 for Federal income taxes, (b) 1979
     for Illinois insurance unitary income taxes and (c) 1987 for Illinois
     non-insurance unitary income taxes. None of the Company or any such
     subsidiaries has made an election to be treated as a "consenting
     corporation" under Section 341(f) of the Code. Except as previously
     described to Zurich and Insurance Partners, there is no material deferred
     inter-company gain within the meaning of the Treasury Regulations
     promulgated under Section 1502 of the Code.

     state, local and foreign income, property, sales, excise, employment,
     payroll, withholding and other taxes, tariffs or governmental charges of
     any nature whatsoever.
 
          (iv) Each Insurance Company is a "life insurance company" within the
     meaning of section 816 of the Code. All tax reserves of such Insurance
     Companies have been determined in accordance with the requirements of
     section 807 or the Code. Except as set forth in Section 3.1(k)(iv) of the
     Disclosure Schedule, neither of the Insurance Companies is subject to any
     adjustment under Section 807(f) of the Code.
 
          (v) The Company has (i) properly elected to file a life/non-life
     consolidated return under Section 1504(c)(2) of the Code and Treasury
     Regulations Section 1.1502-47, and (ii) will file a life/non-life
     consolidated return for the Company and its consolidated group
     subsidiaries, including KILICO and FKLA, for its 1995 taxable year.
 
          (vi) The amount of the policy-holders' surplus account (as defined in
     Section 815 of the Code) of each of the Insurance Companies is accurately
     set forth in Section 3.1(k)(vi) of the Disclosure Schedule.
 
          (vii) Each of the Kemper Funds (as defined herein) has elected to be
     treated as a "regulated investment company" ("RIC") under the Code, and
     has, since the end of the most recent taxable year of each of such Kemper
     Funds that has been closed and for which the statute of limitations for
     assessment has expired, qualified as a RIC.
 
          (l) No Excess Parachute Payments; Section 162(m) of the Code.  (i)
     Except as disclosed in Section 3.1(l) of the Disclosure Schedule, no
     payment, either individually or in combination with any other payment or
     payments, that could be received (whether in cash or property or the
     vesting of property) as a result of any of the transactions contemplated by
     this Agreement by any employee, officer or director of the Company or any
     of its affiliates who is a "disqualified individual" (as such term is
     defined in proposed Treasury Regulation Section 1.280G-1) under any
     employment, severance or termination agreement, other compensation
     arrangement or Benefit Plan currently in effect will be an "excess
     parachute payment" (as such term is defined in section 280G(b)(1) of the
     Code).
 
          (ii) Except as disclosed in Section 3.1(l) of the Disclosure Schedule,
     the disallowance of a deduction under Section 162(m) of the Code for
     employee remuneration will not apply to any amount paid or payable by the
     Company or any subsidiary (other than an Excluded Real Estate Subsidiary)
     of the Company under any contract, Benefit Plan, program, arrangement or
     understanding currently in effect.
 
          (m) Voting Requirements.  The affirmative vote of the holders of a
     majority of the outstanding shares of Common Stock entitled to vote thereon
     at the Stockholders Meeting with respect to the approval of the Merger is
     the only vote of the holders of any class or series of the Company's
     capital stock necessary to approve this Agreement and the transactions
     contemplated by this Agreement.
 
          (n) Compliance with Applicable Laws.  (i) Each of the Company and its
     subsidiaries and the Kemper Funds (as defined below) has in effect all
     Federal, state, local and foreign governmental approvals, authorizations,
     certificates, filings, franchises, licenses, notices, permits and rights
     ("Permits") necessary for it to own, lease or operate its properties and
     assets and to carry on its business as now conducted, and there has
     occurred no default under any such Permit, except for the lack of Permits
     and for defaults under Permits which lack or default individually or in the
     aggregate would not have a Material Adverse Effect with respect to the
     Company. Except as disclosed in the Filed SEC Documents, the Company and
     its subsidiaries and the Kemper Funds are in compliance with all applicable
     statutes, laws, ordinances, rules, orders and regulations of any
     Governmental Entity, except for possible noncompliance which individually
     or in the aggregate would not have a Material Adverse Effect with respect
     to the Company. Except as
 
                                       16
<PAGE>   22
 
     disclosed in the Filed SEC Documents and except for regular and routine
     examinations by state Governmental Entities charged with supervision of
     insurance companies ("Insurance Regulators"), on the date of this
     Agreement, to the knowledge of the Company, no investigation by any
     Governmental Entity with respect to the Company or any of its subsidiaries
     or any of the Kemper Funds is pending or threatened, other than, in each
     case, those that would not have a Material Adverse Effect with respect to
     the Company. For purposes of this Agreement, the "Kemper Funds" shall mean
     the registered investment companies for which the Company or any subsidiary
     acts as investment adviser or sub-adviser.
 
          (ii) The Annual Statements (including without limitation the Annual
     Statements of any separate accounts) for the year ended December 31, 1994,
     together with all exhibits and schedules thereto, and financial statements
     relating thereto, and any actuarial opinion, affirmation or certification
     filed in connection therewith, and the Quarterly Statements for the periods
     ended after January 1, 1995, together with all exhibits and schedules
     thereto, with respect to each subsidiary of the Company that is a regulated
     insurance company (a "Regulated Insurance Company"), in each case as filed
     with the Insurance Regulator of its jurisdiction of domicile, were prepared
     in conformity with statutory accounting practices prescribed or permitted
     by such Insurance Regulator ("SAP") applied on a consistent basis (except
     as set forth in the notes, exhibits or schedules thereto), present fairly,
     to the extent required by and in conformity with SAP, the statutory
     financial condition of such Regulated Insurance Company at their respective
     dates and the results of operations, changes in capital and surplus and
     cash flow of such Regulated Insurance Company for each of the periods then
     ended, and were correct in all material respects when filed and there were
     no material omissions therefrom when filed. No deficiencies or violations
     material to the financial condition or operations of any Regulated
     Insurance Company have been asserted in writing by any Insurance Regulator
     which have not been cured or otherwise resolved to the satisfaction of such
     Insurance Regulator and which have not been disclosed in writing to Zurich
     and Insurance Partners prior to the date of this Agreement.
 
          (iii) Section 3.1(n)(iii) of the Disclosure Schedule contains a
     complete list of all of the Kemper Funds as of the date of this Agreement.
     The Company or one of its subsidiaries acts as investment adviser pursuant
     to valid, binding and enforceable investment advisory agreements for all
     the Kemper Funds listed in Section 3.1(n)(iii) of the Disclosure Schedule
     (which agreements will terminate upon the consummation of the transactions
     contemplated hereby). Except as set forth on Section 3.1(n)(iii) of the
     Disclosure Schedule, there is no money management operation of the Company
     or any of its subsidiaries outside the United States other than the money
     management operation of Kemper Investment Management Company Limited.
 
          (iv) Since January 1, 1994, each of the Kemper Funds has complied with
     the requirements of all laws, rules and regulations applicable to it
     including, without limitation, the 1940 Act, the Securities Act, the
     Exchange Act, the Commodities Exchange Act, as amended, ERISA, the Code and
     all state Blue Sky laws, and the rules and regulations promulgated under
     the foregoing, and has filed with the SEC and all other appropriate

     thereunder, except any filings customarily made by a distributor or
     principal underwriter on behalf of any Kemper Fund in connection with the
     underwriting, distribution or sale of any Kemper Fund shares that may be
     required pursuant to any applicable securities laws or under any
     governmental or self-regulatory authority, which filings have been made by
     the Company or an affiliate of the Company if the Company or an affiliate
     has acted in such capacity (collectively, the "Fund Filings"), except to
     the extent that any noncompliance or failure to file, either individually
     or in the aggregate, would not have a Material Adverse Effect with respect
     to the Company. The Company has made available to ZIP true and complete
     copies of all Fund Filings. The Fund Filings (A) complied in all material
     respects with the requirements of applicable law and (B) did not (as of
     their respective filing dates, mailing dates or effective dates, as the
     case may be) contain any untrue statement of
 
                                       17
<PAGE>   23

     applicable laws, and the rules and regulations promulgated thereunder
     (collectively, the "Separate Account Filings"). The Separate Account
     Filings (1) complied in all material respects with the requirements of
     applicable law and (2) did not (as of their respective filing dates,
     mailing dates or effective dates, as the case may be) contain any untrue
     statement of a material fact or omit to state a material fact required to
     make the statements therein, in the light of the circumstances under which
     they were made, not misleading.
 
          (vi) All proxy statements to be prepared for use by the Kemper Funds
     in connection with the transactions contemplated by this Agreement and the
     KFS Agreement (including, without limitation, the proxy statements to be
     used for the purpose of soliciting voting instructions from the holders of
     Variable Contracts issued by the Insurance Companies), any written
     information provided by the Company and its subsidiaries to each Board of
     Directors or Trustees or other comparable body of the Kemper Funds in
     connection with this Agreement or the transactions contemplated hereby at
     the time such information is provided and, in the case of a proxy
     statement, the date of the shareholder vote for which such proxy statement
     will be used, as then amended or supplemented, and any information
     disseminated to any advisory clients in respect of the transactions
     contemplated hereby at the time such information is disseminated (other
     than, in each case, for information provided or to be provided by ZIP in
     writing relating to ZIP or its affiliates expressly for use therein), in
     each case, will be accurate and complete in all material respects and will
     not be false or misleading with respect to a material fact, or omit to
     state any material fact required to make the statements therein, in the
     light of the circumstances under which they were made, not misleading or
     necessary to correct any statement in any earlier communication that has
     become false or misleading.
 
          (vii) Each of the Company and each of its subsidiaries (other than the
     Excluded Real Estate Subsidiaries) is, if so required by the nature of its
     business or assets, duly registered with the SEC and the various states as
     a broker-dealer and is duly registered with the Commodity Futures Trading
     Commission and the various states as required as a commodities trading
     advisor or commodity pool operator. Each of the Company and each of its
     subsidiaries (other than the Excluded Real Estate Subsidiaries) is, if so
     required by the nature of its business or assets, duly registered with the
     various states as an investment adviser, other than in such states where
     the failure to be so registered (individually or in the aggregate) would
     not have a Material Adverse Effect with respect to the Company.
 
          (viii) The Company and its subsidiaries have complied with the
     requirements of Section 15(f)(1)(B) of the 1940 Act that there not be
     imposed an "unfair burden" on any of the Kemper Funds as a result of the
     Merger, the KFS Sale or the transactions contemplated hereby or thereby or
     any express or implied terms, conditions or understandings applicable
     thereto.
 
          (o) Fair Value of KFS Sale.  As contemplated by Section 1009 of each
     of (i) the Indenture, dated as of January 15, 1987, between the Company and
     The Chase Manhattan Bank, N.A., as amended and supplemented (the "Chase
     Indenture"), and (ii) the Indenture, dated as of September 15, 1993 between
     the Company and The First National Bank of Chicago, as amended and
     supplemented (the "First Chicago Indenture"), the Board of Directors of the
     Company has,
 
                                       18
<PAGE>   24
 
     by resolution duly adopted in accordance with the DGCL, declared that the
     merger of KFS into KFS Acquisition Corp. in the KFS Sale is for
     consideration at least equal to the fair value thereof.
 
          (p) ESOP Sale.  As of the date hereof, the Company has delivered to
     ZIP true and complete copies of the most recent draft of the Newco S-1. The
     Company and its subsidiaries shall not retain any liabilities (whether
     directly or indirectly through guaranties, keepwell agreements, similar
     arrangements or otherwise) of Newco and its subsidiaries (including,
     without limitation, liabilities attributable to employees, former
     employees, directors and consultants of KSH and its subsidiaries) upon
     completion of the ESOP Sale and shall not incur any liabilities in
     connection with the ESOP Sale other than those liabilities set forth in
     Section 3.1(p) of the Disclosure Schedule. After the Effective Time,
     neither Newco nor any of its subsidiaries shall be permitted to use the
     Kemper name except to the extent set forth in Section 3.1(p) of the
     Disclosure Schedule. Prior to the ESOP Sale, the Board of Directors of the
     Company will have, by resolution duly adopted in accordance with the DGCL,
     stated that none of Newco, KSH or KSI is a Restricted Subsidiary within the
     meaning ascribed to such term in Section 101 of each of the Chase Indenture
     and the First Chicago Indenture. The ESOP Sale and the transfer of Newco
     Common Stock in accordance with Section 2.1 will not result in or cause the
     occurrence of an Event of Default (as defined in the Chase Indenture and
     the First Chicago Indenture) or an event or condition that, with the giving

     the Company, any other party thereto, is in default in any material respect
     under any Reinsurance Agreement and, to the knowledge of the Company, there

     anticipated.

agreement. The Company shall (x) keep ZIP reasonably informed of all material
communications between any such offeror and the Company and (y) deliver to ZIP
additional information, material or documents reasonably requested from time to
time by ZIP in connection with any such offer. All binding agreements with a

agreement, without the prior written consent of ZIP, such consent not to be
unreasonably withheld.

price therefor is not more than $500,000, so long as such purchase price
represents, in the reasonable judgment of the Company, fair value for such
asset.

to be unreasonably withheld.
 
     (h) The Company shall, and shall cause its subsidiaries to, take any action
reasonably requested by ZIP in connection with or pertaining to any real estate
asset owned by the Company or any of its subsidiaries; provided, however, that
if, in the reasonable judgment of the Company or the applicable subsidiary, the
taking of such action would materially decrease the value of such asset, the

the Company, either directly or through a subsidiary, does not have any right or
ability to require such action to be performed. The Company shall not be
obligated to cause any Excluded Real Estate Subsidiaries not to take any action
under either Article IV or V of this Agreement if either (A) such Excluded Real
Estate Subsidiary would violate a fiduciary or legal duty by not taking such
action or (B) the Company, either directly or through a subsidiary, does not
have a right or ability to veto or otherwise consent to such action or if the

reasonable steps to be informed of all material business transactions and
management decisions of the Excluded Real Estate Subsidiaries and to exercise
such rights as the Company has, directly or indirectly, with respect to the
Excluded Real Estate Subsidiaries to effectuate the purposes of the covenants of
Articles IV and V relating to the real estate assets owned by such Excluded Real
Estate Subsidiaries. The Company shall notify ZIP in writing promptly after the
Company learns of any action taken, or proposed to be taken, by the Excluded
Real Estate Subsidiaries which, in the absence of this Section 4.11, would
violate the covenants of Article IV and V of this Agreement.

and Insurance Partners, on the other, shall not, and the Company shall not
permit any of its respective subsidiaries

     SECTION 5.5 Indemnification and Insurance.  ZIP and the Surviving

liability for acts or omissions occurring prior to the Effective Time now
existing in favor of the current or former directors, officers or employees of
the Company and its subsidiaries as provided in their respective certificates of
incorporation or by-laws shall survive the Merger and shall continue in full
force and effect in accordance with their terms for a period of not less than
six years from the Effective Time. ZIP and the Surviving Corporation shall cause
to be maintained for a period of not less than six years from the Effective Time
the Company's current directors' and officers' insurance and indemnification
policy to the extent that it provides coverage for events occurring prior to the
Effective Time (the "D&O Insurance") for all persons who are directors, officers
or employees of the Company or any subsidiary of the Company on the date of this
Agreement, if, or to the extent that, the annual premium therefor would not be
in excess of $3,338,000 (the "Maximum Premium"); provided, however, that ZIP and
the Surviving Corporation may, in lieu of maintaining such existing D&O
Insurance as provided above, cause comparable coverage to be provided under any
policy maintained for the benefit of the directors and officers of Zurich or any
of its major United States subsidiaries, so long as (i) the issuer thereof has
at least an equal claims-paying rating and (ii) the material terms thereof are
no less advantageous than the existing D&O Insurance to the extent commercially
available. If the existing D&O Insurance expires, is terminated or cancelled
during such six-year period, ZIP and the Surviving Corporation shall use all
reasonable efforts to cause to be obtained as much D&O Insurance as can be
obtained for the remainder of such period for an annualized premium not in
excess of the Maximum Premium, on terms and conditions no less advantageous than
the existing D&O Insurance to the extent commercially available.
 
     SECTION 5.6 Public Announcements.  ZIP, Zurich and Insurance Partners, on
the one hand, and the Company, on the other hand, shall consult with each other
before issuing, and provide each other the opportunity to review and comment
upon, any press release or other public statements, including such
communications to employees of the Company or its subsidiaries, with respect to
the transactions contemplated by this Agreement, including the Merger, and shall
not issue any such press release or make any such public statement prior to such
consultation, except as may be required by applicable law or government
regulation or decree, court process or by obligations pursuant to any listing
agreement with any national securities exchange.
 
     SECTION 5.7 No Solicitation.  The Company shall not, nor shall it authorize
or permit any of its affiliates or subsidiaries to, nor shall it or any of its
affiliates or subsidiaries authorize or permit any of their respective officers,
directors or employees, or any investment banker, financial advisor, attorney,
accountant or other advisor or representative retained by the Company or any of
its affiliates or subsidiaries to, directly or indirectly (a) solicit, initiate,
encourage (including by way of furnishing information) or take any other action
to facilitate, any inquiry or the making of any proposal which constitutes, or
may reasonably be expected to lead to, any Transaction Proposal or agree to or
endorse any Transaction Proposal or (b) propose, enter into or participate in
any discussions or negotiations regarding any of the foregoing, or furnish to
any other person any information with respect to its business, properties or
assets or any of the foregoing, or otherwise cooperate in any way with, or
assist or participate in, facilitate or encourage, any effort or attempt by any
other person to do or seek any of the foregoing. Clauses (a) and (b) of the
preceding sentence shall not prohibit the Company from (i) furnishing
information pursuant to an appropriate confidentiality letter concerning the
Company and its businesses, properties or assets to a third party who has made
an unsolicited Transaction Proposal that is a Qualified Proposal, (ii) engaging
in discussions or negotiations with such a third party who has made an
unsolicited Transaction Proposal that is a Qualified Proposal or (iii) following
receipt of a Transaction Proposal, taking and disclosing to its stockholders a
position contemplated by Rule 14e-2(a) under the Exchange Act, but in each case
referred to in the foregoing clauses (i) through (iii) only after the Board of
Directors of the Company concludes in good faith based on the advice of outside
counsel that such action is necessary for the Board of Directors of the Company
to comply with its fiduciary obligations to stockholders under applicable law.
Notwithstanding anything
 
                                       34
<PAGE>   40
 
in this Agreement to the contrary, the Company shall immediately inform ZIP,
Zurich and Insurance Partners orally and in writing of the receipt by it (or any
of the other entities or persons referred to above) after the date hereof of any
Transaction Proposal, or any inquiry which could lead to any Transaction
Proposal or to any termination of this Agreement, the terms and conditions of
such Transaction Proposal or inquiry, and the identity of the person making any
such Transaction Proposal or inquiry. The Company will keep ZIP, Zurich and
Insurance Partners fully informed of the status and details of any such
Transaction Proposal or inquiry, and any response to such proposal or inquiry.
Without limiting the foregoing, it is understood that any violation of the
restrictions set forth in the first sentence of this Section 5.7 by any officer,
director or employee of the Company or any of its subsidiaries or any investment
banker, financial advisors, attorney, accountant, or other advisor or
representative of the Company or any of its subsidiaries, whether or not such
person is purporting to act on behalf of the Company or any of its subsidiaries
or otherwise, shall be deemed to be a breach of this Section 5.7 by the Company.
"Transaction Proposal" means any proposal with respect to any acquisition or
purchase of a substantial amount of assets of, or any equity interest in, the
Company or any of its subsidiaries or any tender offer (including a self tender
offer) or exchange offer, merger, consolidation, business combination, sale of
equity securities, recapitalization, liquidation, dissolution or similar
transaction (whether accomplished by means of bulk reinsurance or otherwise)
involving the Company or any of its subsidiaries or any other transaction the
consummation of which would or could reasonably be expected to impede, interfere
with, prevent or materially delay the Merger, the ESOP Sale, the KFS Sale or any
of the other transactions contemplated by this Agreement or materially dilute
the benefits to ZIP, Zurich and Insurance Partners of the Merger, the ESOP Sale,
the KFS Sale or any of the other transactions contemplated by this Agreement
(other than Permitted Sale Transactions, the sale of any real estate assets
contemplated by Section 4.6 or the conversion or exercise of any outstanding
securities of the Company or any of its subsidiaries in accordance with their
terms). "Qualified Proposal" means any Transaction Proposal that would provide
the holders of the Common Stock with cash and/or readily marketable securities
having a value, in the good faith opinion of the Board of Directors of the
Company following consultation with its independent financial advisors, of more
than the sum of $49.50 per share of Common Stock plus, at any time prior to the
distribution of the Newco Common Stock in connection with the ESOP Sale, the
value of the Newco Common Stock per share of Common Stock to be so distributed.
 
     SECTION 5.8 Fiduciary Duties.  The Board of Directors of the Company shall
not (i) withdraw or modify, or propose to withdraw or modify, in a manner
adverse to ZIP, Zurich or Insurance Partners, the approval or recommendation by
such Board of Directors of this Agreement or the Merger, (ii) approve or
recommend, or propose to approve or recommend, any Transaction Proposal or (iii)
approve the Company entering into any agreement with respect to any Transaction
Proposal (including, without limitation, the commencement of a self tender
offer), unless the Company receives an unsolicited Transaction Proposal from a
third party that is a Qualified Proposal and the Board of Directors of the
Company concludes in good faith based on the advice of outside counsel that in
order to comply with its fiduciary obligations to stockholders under applicable
law, it is necessary for the Board of Directors to withdraw or modify its
approval or recommendation of this Agreement or the Merger, approve or recommend
such Transaction Proposal, enter into an agreement with respect to such
Transaction Proposal or terminate this Agreement. In the event the Board of
Directors of the Company takes any of the foregoing actions, the Company shall,
concurrently with the taking of any such action, pay to Zurich or Insurance
Partners (or their designees) the Section 5.12 Fee, plus all of their
Transaction Expenses as required by Section 5.12. Nothing contained in this
Section 5.8 shall prohibit the Company from taking and disclosing to its
stockholders a position contemplated by Rule 14e-2(a) promulgated under the
Exchange Act or from making any disclosure to the Company's stockholders which,
in the good faith reasonable judgment of the Board of Directors of the Company
based on the advice of outside counsel, is required under applicable law,
provided that the Company does not withdraw or modify, or propose to withdraw or
modify, its position with respect to the Merger or approve or recommend, or
propose to approve or recommend, a Transaction Proposal. Notwithstanding
anything contained in this Agreement to the contrary, any
 
                                       35
<PAGE>   41
 
action by the Board of Directors permitted by this Section 5.8 shall not
constitute a breach of this Agreement by the Company if, concurrently with such
action, the Company pays the Section 5.12 Fee and the Transaction Expenses as
required by this Section 5.8.
 
     SECTION 5.9 Consents, Approvals and Filings.  (a) The Company, ZIP, Zurich
and Insurance Partners will make and cause their respective subsidiaries to make
all necessary filings, as soon as practicable, including, without limitation,
those required under the HSR Act, the Securities Act, the Exchange Act, the 1940
Act, the Advisers Act and applicable state insurance laws in order to facilitate
prompt consummation of the Merger and the other transactions contemplated by
this Agreement. In addition, the Company, ZIP, Zurich and Insurance Partners
will each use their commercially reasonable efforts, and will cooperate fully
with each other (i) to comply as promptly as practicable with all governmental
requirements applicable to the Merger and the other transactions contemplated by
this Agreement, (ii) to obtain as promptly as practicable all necessary permits,
orders or other consents of Governmental Entities and consents of all third
parties necessary for the consummation of the Merger and the other transactions
contemplated by this Agreement and (iii) to obtain consents from Insurance
Regulators with respect to KILICO that provide that the unassigned surplus of
KILICO will be reset to zero at the Effective Time; provided, however, that none
of the Company, the Surviving Corporation, ZIP, KFS Acquisition Corp., Zurich or
Insurance Partners shall be required to comply with any governmental
requirements or permits, orders or other consents of Governmental Entities that
(i) prohibit or restrict the ownership or operation by the Surviving
Corporation, Zurich or Insurance Partners (or any of their respective affiliates
or subsidiaries) of any portion of the Company's business or assets which is
material to the business of the Company and its subsidiaries taken as a whole,
or compels the Surviving Corporation, Zurich or Insurance Partners (or any of
their respective affiliates or subsidiaries) to dispose of or hold separate any
portion of the business of Zurich or Insurance Partners or the Company's
business or assets which is material to the business of the Company and its
subsidiaries taken as a whole, (ii) impose any material limitations on the
ability of Zurich or Insurance Partners or any of their respective affiliates or
subsidiaries effectively to control in any material respect the business and
operations of the Company and its subsidiaries, or (iii) otherwise would
materially adversely affect the Company and its subsidiaries taken as a whole.
Each of the Company, ZIP, Zurich and Insurance Partners shall use all
commercially reasonable efforts to provide such information and communications
to Governmental Entities as such Governmental Entities may reasonably request.
 
     (b) Each of the parties shall provide to the other party copies of all
applications as early as practicable in advance of filing or submission of such
applications to Governmental Entities in connection with this Agreement.
 
     SECTION 5.10 Company Satisfaction of the Conditions of Section 15 of the
1940 Act.  (a) The Company shall, and shall cause each of KFS and the applicable
subsidiaries of KFS (collectively, with KFS, the "Asset Management
Subsidiaries") to, use their commercially reasonable efforts to cause the boards
of trustees/directors of the Kemper Funds (other than Kemper Investors Fund
("KINF")) to approve, and to solicit their respective shareholders as promptly
as practicable with regard to the approval of, new investment advisory
agreements with the Asset Management Subsidiaries acting as investment advisers
for such funds, to be effective on or as promptly as practicable after the
Effective Time, pursuant to the provisions of Section 15 of the 1940 Act, and
consistent with all requirements of the 1940 Act applicable thereto, provided
that such agreements are identical in all respects to the existing agreements
other than the term of the agreement.
 
     (b) The Company shall cause each Insurance Company and KFS to use their
commercially reasonable efforts to cause the board of trustees of KINF to
approve, and to solicit voting instructions from owners of Variable Contracts
issued by the Insurance Companies as promptly as practicable with regard to the
approval of, a new investment advisory agreement with KFS, to be effective on or
as promptly as practicable after the Effective Time, pursuant to the provisions
of Section 15 of the 1940 Act, and consistent with all requirements of the 1940
Act applicable thereto, provided that such agreement is identical in all
respects to the existing agreement other than the term of the agreement.

<PAGE>   42
 
     (c) The Company shall, and shall cause each of the Asset Management
Subsidiaries to, use their commercially reasonable efforts to ensure the
satisfaction of the conditions set forth in Section 15(f) of the 1940 Act with
respect to each of the Kemper Funds (including KINF), including the requirement
that no "unfair burden" (as defined in Section 15(f)(1)(B) of the 1940 Act) be
imposed on any of the Kemper Funds.
 
     SECTION 5.11 Advisory Contract Consents.  As promptly as practicable, the
Company shall cause the non-investment company advisory clients of the Asset
Management Subsidiaries to be informed of the transactions contemplated by this
Agreement and shall give such clients an opportunity to terminate their advisory
contracts with such Asset Management Subsidiaries or any of their affiliates.
Unless written consent is required by the terms of such advisory contracts, ZIP,
Zurich and Insurance Partners agree that the Company may satisfy this obligation
to the extent that applicable law permits insofar as it relates to noninvestment
company advisory clients by providing them with the notice contemplated by the
first sentence of this Section 5.11 and obtaining such clients' consent in the
form of actual or implied consent by way of informing such clients of the Asset
Management Subsidiaries' intention to continue the advisory services, pursuant
to the Asset Management Subsidiaries' existing contracts with such clients,
subject to such clients' right to terminate such contracts within sixty (60)
days of receipt of such notice, and that each such client's consent will be
implied if it continues to accept the services without rejection during such
specified sixty-day period.
 
     SECTION 5.12 Certain Fees and Expenses.  (a) The Company shall pay to
Zurich and Insurance Partners (or their designees) a single fee of $80 million
(the "Section 5.12 Fee"), upon the earlier of demand or at the time specified in
Section 5.8, if (i) this Agreement is terminated pursuant to Section 7.1(b), (c)
or (d) or (ii) the Section 5.12 Fee is payable pursuant to Section 5.8.
 
     (b) If this Agreement is terminated pursuant to Section 7.1(a) or (e),
provided that any such termination pursuant to Section 7.1(e) is based on a
breach of a covenant or agreement or a willful breach of a representation or
warranty on the part of the Company, then the Company shall pay Zurich and
Insurance Partners (or their designees) (i) a single fee of $40 million, upon
demand following the date of such termination and (ii) if within 12 months after
the date of such termination of this Agreement, a transaction contemplated by a
Transaction Proposal shall have occurred or the Company shall have entered into
a definitive agreement relating to a transaction contemplated by a Transaction
Proposal, an additional single fee of $40 million which, in the case such a
transaction shall have occurred, shall be payable upon demand and, in the case
such transaction shall not have occurred, shall be payable upon demand on the
earlier of (x) the date such transaction occurs and (y) six months after a
definitive agreement relating to such transaction has been entered into by the
Company.
 
     (c) If this Agreement is terminated pursuant to Section 7.1(h), (i) or (j),
and such termination is due to the fact that any of the conditions set forth in
Sections 6.1(c), 6.1(e)(i)(b), 6.1(g), 6.2(a) (as qualified below, but without
limiting the provisions of Section 5.12(b) hereof), 6.2(c), 6.2(e), 6.2(i),
6.2(j), 6.2(k) or 6.2(l) have not been satisfied or waived, and if within 12
months after the date of such termination a transaction contemplated by a
Transaction Proposal shall have occurred or the Company shall have entered into
a definitive agreement relating to a transaction contemplated by a Transaction
Proposal, then the Company shall pay Zurich and Insurance Partners (or their
designees) a single fee of $40 million, which, in the case such a transaction
shall have occurred, shall be payable upon demand and, in the case such
transaction shall not have occurred, shall be payable upon demand on the earlier
of (x) the date such transaction occurs and (y) six months after a definitive
agreement relating to such transaction has been entered into by the Company. If
the termination of the Agreement pursuant to Section 7.1(h) (and without
limiting the provisions of Section 5.12(b) hereof) is due to the failure to
satisfy the condition set forth in Section 6.2(a), the payment required by the
preceding sentence shall only be payable if the condition is not satisfied
because of the failure of a representation or warranty to meet the applicable
standard of truthfulness and correctness set forth in said Section 6.2(a) as of
the date of this Agreement.
 
                                       37

     (d) For purposes of this Section 5.12, "Transaction Proposal" shall not

5% of all securities of the Company or such subsidiary entitled to vote
generally in the election of directors.
 
     (e) Whether or not the Merger is consummated or this Agreement is
terminated and in addition to any other amounts payable under this Section 5.12,
the Company agrees to pay all of its Transaction Expenses and the Transaction
Expenses of ZIP, Zurich and Insurance Partners; provided, however, that the
Company shall have no obligation to pay any Transaction Expenses of ZIP, Zurich
and Insurance Partners if (i) ZIP, Zurich or Insurance Partners fails to close
the transactions contemplated hereby after each of the closing conditions set
forth in Sections 6.1 and 6.2 have been fully satisfied (or deemed satisfied
pursuant to Section 6.4) (unless such failure to close occurs as a result of any
action taken by the Company) or (ii) the Company terminates this Agreement
pursuant to Section 7.1(f) (unless the breach by ZIP, Zurich or Insurance
Partners occurs as a result of any action taken by the Company). To the extent
provided for in the preceding sentence, the Transaction Expenses of ZIP, Zurich
and Insurance Partners shall be paid by the Company on the earlier of the
Effective Time, the date of termination of this Agreement, or at the time
specified in Section 5.8. For purposes of this Section 5.12, "Transaction
Expenses" shall mean, with respect to any party, the documented out-of-pocket
expenses (except to the extent expressly set forth below) of such party (whether
or not incurred prior to the date hereof) arising out of, relating to or
incidental to the discussion, evaluation, negotiation, documentation and closing
or potential closing of the Merger, the KFS Sale, the sale of real estate assets
in accordance with Section 4.6, the financing of such transactions, and all
other transactions contemplated by this Agreement (including, without
limitation, the fees, disbursements and other expenses of attorneys (including
allocated in-house attorneys costs), accountants, actuaries, investment bankers,
consultants and any other advisors (which may include fees, disbursements and
other expenses payable to affiliates of Zurich or Insurance Partners), and all
printing costs and filing fees incurred in connection with such transactions);
provided, however, that the Transaction Expenses payable under this Section 5.12
shall not exceed an aggregate of $35 million. For purposes of this Section 5.12,

means Zurich and its affiliates.
 
     (f) In addition to the other provisions of this Section 5.12, upon demand,
the Company agrees to reimburse ZIP, Zurich and Insurance Partners for all
out-of-pocket costs, fees and expenses, including, without limitation, the fees
and disbursements of counsel and the expenses of litigation, incurred in
connection with collecting Transaction Expenses, the Section 5.12 Fee or any
other fee described in this Section 5.12 as a result of any breach by the
Company of its obligations under this Section 5.12.
 
     (g) All amounts payable under this Section 5.12 shall be paid in
immediately available funds to an account or accounts designated by ZIP. The
Company shall not be required to pay the Section 5.12 Fee or the same expense
reimbursement more than once.

business days prior to the date on which the annuities are purchased.
 
     SECTION 5.16 Board Action Relating to Stock Options and Phantom Stock
Rights.  (a) As soon as practicable following the date of this Agreement, the
Board of Directors of the Company (or, if appropriate, any committee
administering a Company Stock Option Plan) shall adopt such resolutions or take
such actions as may be required to cancel outstanding Company Stock Options and
Phantom Stock Rights in accordance with Section 2.2, and the Company shall have
taken such actions prior to the record date of the distribution of Newco Common
Stock contemplated by the ESOP Sale with respect to the Company Stock Options
(other than adjustment of the exercise price of Company Stock Options granted in
April 1994 the exercise price of which is $58 per share, but only to the extent
of an adjustment to the exercise price thereof that does not reduce such
exercise price below $50 per share) and Phantom Stock Rights to preclude any
anti-dilution adjustment (whether to the exercise price, the appreciation base,
the number of shares of Common Stock subject thereto or otherwise) that
otherwise would have occurred as a result of the ESOP Sale (collectively, the
"Anti-dilution Actions") (it being understood that the holders may receive
shares of Newco Common Stock in lieu of such adjustment) and shall make such
other changes to the Company Stock Option Plans and Phantom Stock Rights as it
deems appropriate to give effect to the Merger (subject to the approval of ZIP,
which shall not be unreasonably withheld).
 
     (b) As soon as practicable following the date of this Agreement, the
Company shall cause the Board of Directors of KFC (or, if appropriate, any
committee administering any plan relating to the KFC Stock Options) to take such
actions as may be required to cancel outstanding KFC Stock Options effective as

anti-dilution adjustments with respect to the KFC Stock Options shall be
required in connection with the ESOP Sale).
 
     SECTION 5.17 Lumbermens Series C Preferred Stock.  If, prior to the
Effective Time, Zurich, Insurance Partners and Lumbermens enter into an
agreement relating to the Lumbermens Agreement which involves action, with
respect to the Series C Preferred Stock, in the Merger, that is different than
as contemplated hereby, the Company shall take such actions (including agreeing
to amend this Agreement if necessary), as ZIP reasonably requests, to effectuate
such agreement.
 
     SECTION 5.18 Merger Preferred Stock.  If, prior to the Effective Time, ZIP
requests that the Company authorize one or more new series of Preferred Stock to
be issued in connection with the Merger, the Company shall file a certificate of
designation or certificates of designation, in forms delivered by ZIP and, as to
form, reasonably acceptable to the Company, with respect to such new series of

Effective Time and, if necessary, shall amend this Agreement to permit the
issuance of such Preferred Stock in the Merger.

Controlled Entity shall, if requested by ZIP, use commercially reasonable
efforts to cause any payment to an employee under any contract, Benefit Plan,

payment which otherwise would be disallowed as a deduction under Section 162(m)
of the Code; provided,
 
                                       39
<PAGE>   45
 
however, that such delay shall occur only if not otherwise legally inconsistent
with the terms of any such contract, Benefit Plan, program, arrangement or
understanding. The Surviving Corporation shall make any such delayed payments as
soon as practicable after the Closing Date in accordance with the terms of the
applicable contract, Benefit Plan, program, arrangement or understanding.
 
     (b) For the one year period beginning on the Closing Date, the Surviving
Corporation shall continue to maintain each of the following Benefit Plans: (i)
all qualified "defined contribution" plans (as defined in Section 414(i) of the
Code), (ii) all supplemental plans, to the extent such plans provide benefits
which cannot otherwise be provided, as a result of applicable Code limitations,
under the aforementioned defined contribution plans and (iii) all "welfare
plans" (as defined in section 3(1) of ERISA); provided, however, that the
aforementioned clauses (ii) and (iii) shall only apply with respect to the
lesser of the level of benefits provided (A) on March 13, 1994 (except as
applied to employees of FKLA and with respect to the General Severance Program
included in the employee handbook first distributed on August 12, 1994, such
program as in effect on such date) and (B) immediately prior to the Effective
Time, under such plans (or any predecessor thereof) as then in effect on such
relevant date.
 
     (c) As of the Effective Time, Continuing Employees then participating in
each of the aforementioned defined contribution plans shall have nonforfeitable
rights to receive the amounts then credited to their accounts thereunder, as
thereafter from time to time adjusted for subsequent investment gain and loss
experience thereon; provided, however, that the provisions of this subsection
(c) shall apply with respect to any such plan only to the extent that any
forfeitures thereunder would otherwise not be used to reduce future employer
contributions otherwise to be made thereto.
 
     (d) Each Continuing Employee shall be given full credit for his or her
pre-Effective Time service with the Company and each of its subsidiaries and
predecessor employers, but only to the extent such service is recognized under
the terms of the specific Benefit Plan of the Company or Company subsidiary with
respect to which such service would be taken into account as of the Effective
Time (disregarding any amendment, board of director, benefit plan committee,
plan administrator or other action after the date hereof), for all purposes
(other than for benefit accrual, level of benefits or determination of the rate
or rates of contribution) under each Benefit Plan, program or arrangement
offered to Continuing Employees on or after the Effective Time which corresponds
to the Company or Company subsidiary plan under which such service was credited
prior to the Effective Time.
 
     (e) As used in this Section 5.20, "Continuing Employee" means each employee
of the Company or a subsidiary of the Company as of the Effective Time.
 
     SECTION 5.21 Lumbermens Agreement.  The Company shall keep ZIP informed of
all actions taken by the Company (and its affiliates) and/or, to the extent
known by the Company, Lumbermens (and its affiliates), and all material
communications between the Company and Lumbermens, pursuant to or in connection
with the Lumbermens Agreement or the transactions and events contemplated
thereby. If Lumbermens breaches any obligation under the Lumbermens Agreement,
the Company shall take all actions reasonably requested by ZIP with respect to
the enforcement of such obligation.

                                        1
<PAGE>   5
 
to delay the Closing (i) until another later date (which shall not be later than
January 4, 1996) or (ii) until a date after the consummation of the Kemper
Merger (such third business day or such other date being the "Closing Date").
 
     SECTION 1.3. Effective Time.  Merger Sub shall file with the Secretary of
State of the State of Delaware (the "Delaware Secretary of State") on the
Closing Date (or on such other date as the Company and Merger Sub may agree) a
certificate of merger (the "Certificate of Merger") or other appropriate
documents, executed in accordance with the relevant provisions of the DGCL, and
make all other filings or recordings required under the DGCL in connection with
the Merger. The Merger shall become effective upon the filing of the Certificate
of Merger with the Delaware Secretary of State, or at such later time as is
specified in the Certificate of Merger (the "Effective Time").
 
     SECTION 1.4. Effects of the Merger.  The Merger shall have the effects set
forth in Section 259 of the DGCL.
 
     SECTION 1.5. Certificate of Incorporation; Bylaws.  (a) The Certificate of
Incorporation of Merger Sub (the "Charter"), as in effect immediately prior to
the Effective Time, shall be amended as of the Effective Time so that paragraph
1 of the Charter shall read in its entirety as follows: "1. The name of the
corporation (the "Corporation") is Kemper Financial Services, Inc." and, as so
amended, the Charter shall, from and after the Effective Time, be the
Certificate of Incorporation of the Surviving Corporation until thereafter
changed or amended as provided therein or by applicable law.
 
     (b) The By-laws of Merger Sub as in effect at the Effective Time shall,
from and after the Effective Time, be the By-laws of the Surviving Corporation
until thereafter changed or amended as provided therein or by applicable law.
 
     SECTION 1.6. Directors.  The directors of Merger Sub at the Effective Time
shall, from and after the Effective Time, be the directors of the Surviving
Corporation, until the earlier of their death, resignation or removal or until
their respective successors are duly elected and qualified, as the case may be.
 
     SECTION 1.7. Officers.  The officers of Merger Sub at the Effective Time
shall, from and after the Effective Time, be the officers of the Surviving
Corporation, until the earlier of their death, resignation or removal or until
their respective successors are duly elected and qualified, as the case may be.
 
     SECTION 1.8. Effect on Capital Stock.  At the Effective Time, by virtue of
the Merger and without any action on the part of the holders of (i) any shares
of common stock, par value $10.00 per share, of the Company (the "Common Stock")
or any other shares of capital stock of the Company or (ii) any shares of
capital stock of Merger Sub:
 
          (a) Common Stock of Merger Sub.  Each share of common stock, par value
     $.01 per share, of Merger Sub ("Merger Sub Common Stock") issued and
     outstanding immediately prior to the Effective Time shall remain
     outstanding after the Merger.
 
          (b) Cancellation of Treasury Stock.  Each share of Common Stock issued
     and outstanding immediately prior to the Effective Time that is owned by
     the Company or by any subsidiary of the Company shall automatically be
     cancelled and retired and shall cease to exist, and no cash or other
     consideration shall be delivered or deliverable in exchange therefor.
 
          (c) Conversion of Common Stock.  Each share of Common Stock issued and
     outstanding immediately prior to the Effective Time (other than shares to
     be cancelled in accordance with Section 1.8(b)) shall be converted into the
     right to receive $900,000 per share, without interest (the "Merger
     Consideration").
 
          (d) Cancellation and Retirement of Common Stock.  As of the Effective
     Time, all certificates representing shares of Common Stock, other than
     certificates representing shares to be cancelled in accordance with Section
     1.8(b), issued and outstanding immediately prior to the Effective Time,
     shall no longer be outstanding and shall automatically be cancelled and
     retired and shall
 
                                        2
<PAGE>   6
 
     cease to exist, and each holder of a certificate representing any such
     shares of Common Stock shall cease to have any rights with respect thereto,
     except the right to receive the Merger Consideration upon surrender of such
     certificate.
 
          (e) Payment of Merger Consideration.  Within two business days after
     the Effective Time, upon surrender to the Surviving Corporation of all
     certificates previously representing outstanding shares of Common Stock,
     the Surviving Corporation shall pay the Merger Consideration to the holder
     of such certificates.
 
     SECTION 1.9. Subsequent Actions.  If, at any time after the Effective Time,
the Surviving Corporation shall consider or be advised that any deeds, bills of
sale, assignments, assurances or any other actions or things are necessary or
desirable to vest, perfect or confirm of record or otherwise in the Surviving
Corporation its right, title or interest in, to or under any of the rights,
properties or assets of either of the Company or Merger Sub acquired or to be
acquired by the Surviving Corporation as a result of, or in connection with, the
Merger or otherwise to carry out this Agreement, the officers and directors of
the Surviving Corporation shall be authorized to execute and deliver, in the
name and on behalf of either the Company or Merger Sub, all such deeds, bills of

         REPRESENTATIONS AND WARRANTIES OF THE COMPANY, KFC AND KEMPER
 
     Each of the Company, KFC and Kemper hereby represents and warrants to
Zurich and Merger Sub as follows:

KFC, the Company and each material subsidiary of the Company is a corporation
duly organized, validly existing and in good standing under the laws of the
jurisdiction in which it is incorporated and has the requisite corporate power
and authority to carry on its business as now being conducted. Each of the
Company and each material subsidiary of the Company is duly qualified or
licensed to do business and is in good standing in each jurisdiction in which
the nature of its business or the ownership or leasing of its properties makes
such qualification or licensing necessary, other than in such jurisdictions
where the failure to be so qualified or licensed (individually or in the
aggregate) would not have a Material Adverse Effect with respect to the Company.
The Company has delivered to Zurich complete and correct copies of its
Certificate of Incorporation and By-laws, as amended to the date of this
Agreement.
 
     SECTION 2.2. Capital Structure.  The authorized capital stock of the

on which the stockholders of the Company or any material subsidiary of the
Company may vote are issued or outstanding. Except as disclosed in Section 2.2
of the Disclosure Schedule, all the outstanding shares of capital stock of each

subsidiary of the Company to issue, sell or transfer, repurchase, redeem or
otherwise acquire or vote any shares of the capital stock of the Company or any
material subsidiary of the Company or (ii) restricts the transfer of Common
Stock.
 
     SECTION 2.3. Authority; Noncontravention; Binding Effect.  Each of Kemper,

Agreement, subject, in the case of KFC, to the approval of the stockholders of
KFC. The execution and delivery of this Agreement by Kemper, KFC and the Company
and the consummation by Kemper, KFC and the Company of the transactions
contemplated hereby have been duly authorized by all necessary corporate action
on the part of Kemper, KFC and the Company and by KFC as the sole stockholder of
the Company, subject, in the case of KFC, to the approval of the stockholders of

the statements therein, in the light of the circumstances under which they are

become false or misleading; provided, however, that no representation or
warranty is made by Kemper, KFC or the Company with respect to statements made
in the Information Statement based on information supplied in writing by Zurich

and its related trust is exempt from taxation under Code Section 501(a); (ii)
such Benefit Plan has been maintained and administered at all times in
compliance with its terms and applicable laws and regulations; (iii) no event
has occurred and there exists no circumstance under which the Company could
directly, or indirectly through a Commonly Controlled Entity, incur liability
under ERISA, the Code (including, without limitation, Section 4980B of the Code)
or otherwise (other than routine claims for benefits); (iv) there are no
actions, suits or claims (other than routine claims for benefits) pending or, to

                                        7
<PAGE>   11
 
where the failure thereof, either individually or in the aggregate, would not
have a Material Adverse Effect with respect to the Company.
 
     (d) With respect to each Benefit Plan that is subject to Title IV of ERISA:
except as set forth in Section 2.8(d) of the Disclosure Schedule, (i) as of the
date of the most recent actuarial valuation, the present value of all benefit
liabilities (as defined in ERISA Section 4001(a)(16)) does not exceed the then
current fair market value of the assets of such plan (determined by using the
actuarial assumptions used for the most recent actuarial valuation); (ii) the
Company has not incurred, nor will it incur, directly, or indirectly through a
Commonly Controlled Entity, any liability arising from a plan termination
(including plans that have been formally terminated); (iii) the Company has
complied with all laws, regulations and pronouncements pertaining to the
termination of any such Benefit Plan, including, but not limited to, the
selection of an insurance company to provide benefits under such terminated
Benefit Plan; and (iv) the Company has taken all commercially reasonable actions
to insulate assets of any such Benefit Plan from depreciating in value except in
the case of any of the foregoing where the failure thereof, either individually
or in the aggregate, would not have a Material Adverse Effect with respect to
the Company.
 
     (e) Except as set forth in Section 2.8(e) of the Disclosure Schedule, with
respect to those Benefit Plans that are "welfare plans" (as defined in Section
3(1) of ERISA), there are no reserves, assets, surpluses or prepaid premiums
under any such plans, the existence of which, either individually or in the
aggregate, would have a Material Adverse Effect with respect to the Company.

neither the approval or execution of this Agreement nor the consummation of the
transactions contemplated by this Agreement will (i) entitle any individual to
severance pay or (ii) accelerate the time of payment or vesting of, or increase
the amount of, compensation due to any individual; except in the case where any
of the foregoing, either individually or in the aggregate, would not have a
Material Adverse Effect with respect to the Company.

affecting the business of the Company or any of its subsidiaries, and the
Company and its subsidiaries have not experienced any strike, slowdown or work
stoppage, lockout or other collective labor action within the last three years,
(ii) neither the Company nor any of its subsidiaries is a party to any
collective bargaining agreement or other labor union contract applicable to
employees of the Company or its subsidiaries nor does the Company know of any
activities or proceedings of any labor union to organize any such employees
currently taking place or planned or that have occurred within the last three
years and (iii) there is no representation claim or petition pending before the
National Labor Relations Board and no question concerning representation exists
relating to the employees of the Company and its subsidiaries.
 
     (h) No circumstance described in Part I, Section (g) of Prohibited
Transaction Class Exemption 84-14, as published as amended at 50 Fed. Reg. 41430
(October 10, 1995) has occurred that would prevent the Company from acting as a
"qualified professional asset manager" (as defined in such class exemption).
 
     (i) No guaranteed interest contracts issued by any insurance company that
is currently insolvent, or has been in insolvency proceedings, are held by any
of the Benefit Plans except for such contracts, which, either individually or in
the aggregate, would not have a Material Adverse Effect with respect to the
Company.
 
     (j) Within the five-year period ending on the date of this Agreement,
neither the Company nor any member of its "controlled group" (within the meaning
of Section 4069 of ERISA) has engaged in any transaction which could result in
liability to any of the parties to this Agreement, or to any other
 
                                        8
<PAGE>   12
 
members of their respective controlled groups (as above so defined) pursuant to
Section 4069 of ERISA or otherwise with respect to any Benefit Plan maintained
by the Company or any other member of its controlled group (as above so defined)
during such five-year period, but not so maintained as of the date of this
Agreement, except where the existence of such a liability would not have a
Material Adverse Effect with respect to the Company.
 
     SECTION 2.9. Litigation.  As of the date of this Agreement, except as
disclosed in Section 2.9 of the Disclosure Schedule or the Filed SEC Documents,
there is no suit, action, proceeding, arbitration or investigation pending or,
to the knowledge of Kemper, KFC or the Company, threatened against the Company
or any subsidiary of the Company that, individually or in the aggregate with any
other such suits, actions, proceedings, arbitrations or investigations, could
reasonably be expected to have a Material Adverse Effect with respect to the
Company, nor is there any judgement, decree, injunction, rule or order of any
Governmental Entity or arbitrator outstanding against the Company or any
subsidiary of the Company that, individually or in the aggregate, could
reasonably be expected to have a Material Adverse Effect with respect to the
Company.
 
     SECTION 2.10. Taxes.  (a) Kemper is the common parent of an affiliated
group of corporations (within the meaning of Section 1504(a) of the Code)
eligible to file consolidated federal income tax returns, of which the Company
and each of its subsidiaries is a member. From January 1, 1987 through the
Closing Date, Kemper has included (or, with respect to the taxable year ending
on the Closing Date, will include) the Company and each of its subsidiaries in
its consolidated federal income tax return as a member of the affiliated group
of which Kemper is the common parent.
 
     (b) Except as set forth on Section 2.10(b) of the Disclosure Schedule, each
of the Company and each of its subsidiaries has filed (or joined in the filing
of) all tax returns and reports required to be filed by it or requests for
extensions to file such returns or reports have been timely filed, granted and
have not expired. All tax returns filed by the Company and each of its
subsidiaries (or in which the Company and each of its subsidiaries has joined)
are complete and accurate except to the extent that such failure to be complete
and accurate would not have a Material Adverse effect with respect to the
Company. The Company and each of its subsidiaries has paid (or Kemper has paid
on behalf of the Company and its subsidiaries) all taxes shown as due on such
returns, and the 1994 Company Audited Financial Statements reflect, in
management's best judgment, an adequate reserve for all taxes payable by the
Company and its subsidiaries for all taxable periods and portions thereof
accrued through the date of such financial statements.
 
     (c) Except as set forth on Section 2.10(c) of the Disclosure Schedule, no
deficiencies for any taxes have been proposed, asserted or assessed against the
Company or any of its subsidiaries (or against Kemper in respect of the Company
or any of its subsidiaries) that are not adequately reserved for and no requests
for waivers of the time to assess any federal or Illinois taxes or any other
material taxes have been granted or are pending. The federal and Illinois income
tax returns of Kemper and each of its subsidiaries (including the Company and
its subsidiaries) consolidated in such returns have been examined by and settled
with the United States Internal Revenue Service or the Illinois Department of
Revenue, as the case may be, or the statute of limitations on assessment or
collection of any federal or Illinois income taxes due from Kemper or any of its
subsidiaries (including the Company and its subsidiaries) has expired, for all
taxable years of Kemper or any of its subsidiaries (including the Company and
its subsidiaries) through the taxable year ended December 31, (a) 1986 for
federal income taxes and (b) 1987 for Illinois non-insurance unitary income
taxes. None of the Company or any of its subsidiaries has made an election to be
treated as a "consenting corporation" under Section 341(f) of the Code. Except
as previously described to Zurich, there is no material deferred inter-company
gain within the meaning of the Treasury Regulations promulgated under Section
1502 of the Code.
 
     (d) Each of the Funds has elected to be treated as a "regulated investment
company" ("RIC") under the Code, and has, since the end of the most recent
taxable year of each of such Funds that has been closed and for which the
statute of limitations for assessment has expired, qualified as a RIC.
 
                                        9
<PAGE>   13
 
     (e) As used in this Agreement, "taxes" shall include all federal, state,
local and foreign income, property, sales, excise, employment, payroll,
withholding and other taxes, tariffs or governmental charges of any nature
whatsoever.
 
     SECTION 2.11. No Excess Parachute Payments; Section 162(m) of the
Code.  (a) Except as disclosed in Section 2.11 of the Disclosure Schedule, no
payment, either individually or in combination with any other payments, that

to own, lease or operate its properties and assets and to carry on its business
as now conducted, and there has occurred no default under any such Permit,
except for the lack of Permits and for defaults under Permits which lack or

affiliate of Kemper if Kemper or an affiliate has acted in such capacity

be accurate and complete in all material respects and will not contain any
untrue statement of a material fact, or omit to state any material fact required
to make the statements therein, in the light of the circumstances under which
they were made, not misleading or necessary to correct any statement in any

(c) shall apply with respect to any such plan only to the extent that any
forfeitures thereunder would otherwise not be used to reduce future employer
contributions otherwise to be made thereto.
 
     (d) Each Continuing Employee shall be given full credit for his or her
pre-Effective Time service with the Company and each of its subsidiaries and
predecessor employers, but only to the extent such service is recognized under

plan administrator or other action after the date hereof), for all purposes
(other than for benefit accrual, level of benefits or determination of the rate
or rates of contribution) under each Benefit Plan, program or arrangement
offered to Continuing Employees on or after the Effective Time which corresponds
to the Company or Company subsidiary plan under which such service was credited

     Section 6.4. Satisfaction of Closing Conditions.  If Merger Sub makes an

on which Merger Sub delivers the Section 1.2(b)(i) Notice (the "Preliminary
Closing Date"), a preliminary closing shall take place at the offices of Willkie

at 9:00 a.m., at which Kemper, KFC and the Company shall seek to fulfill all
conditions to the obligations of Zurich and Merger Sub to effect the Merger set
forth in Sections 6.1 and 6.2, (other than Section 6.2(l) of the Kemper Merger
Agreement (which is incorporated by reference pursuant to Section 6.2(a) of this
Agreement) but including, without limitation, the delivery of the officers'
certificates under Sections 6.2(b) and (c)) (the "Preliminary Closing
Conditions"). If Kemper, KFC and the Company shall fulfill all of the

Merger Sub to effect the Merger set forth in Sections 6.2(c), (e), (f), (g) and
(h) of the Kemper Merger Agreement (which are incorporated by reference in this
Agreement pursuant to Section 6.2(a) of this Agreement) shall be deemed to have
been satisfied on the Closing Date and (B) the conditions set forth in Section
6.2(a) of the Kemper Merger Agreement (which is incorporated by reference in
this Agreement pursuant to Section 6.2(a) of this Agreement) and in Section
6.2(b) of this Agreement must be satisfied or waived on the Closing Date, except
that such conditions to the extent they apply to the truth and correctness as of
the Closing Date of the representations and warranties set forth in Sections
3.1(e) through (l), (n), (p) through (u), and (x) through (bb) of the Kemper
Merger Agreement and Sections 2.5 through 2.11 and 2.13 through 2.17 of this
Agreement and Section 2.18 of this Agreement, to the extent that
 
                                       17
<PAGE>   21
 
such Section 2.18 incorporates by reference Sections 3.1(e) through (l), (n),
(p) through (u), and (x) through (bb) of the Kemper Merger Agreement, shall be
deemed to be satisfied on the Closing Date unless the failure to satisfy such
condition is as a result of any willful action or willful inaction by Kemper,
KFC or the Company, any of their subsidiaries or any officers or directors
thereof. If Kemper, KFC and the Company shall fulfill the Preliminary closing
Conditions, then the closing shall occur on a business day specified in a
written notice from Merger Sub to the Company, which shall be not fewer than
three business days after the date on which Merger Sub delivers such notice and
shall be no later than January 4, 1996. If Kemper, KFC and the Company shall not
fulfill all of the Preliminary Closing Conditions on the Preliminary Closing
Date, Kemper, KFC and the Company must fulfill all of the conditions set forth
in Sections 6.1 and 6.2 on the Closing Date as if no preliminary closing
occurred.

     breaching party of notice of such breach; provided, however, that if the

     failure to consummate the Merger is the result of a willful and material
     breach of this Agreement by the party seeking to terminate this Agreement;
 
          (f) by Kemper, if the conditions set forth in Sections 6.1 and 6.3 of
     this Agreement shall not have been satisfied or waived and the Merger shall
     not have been consummated on or before February 29, 1996, unless the
     failure to consummate the Merger is the result of a willful and material
     breach of this Agreement by the party seeking to terminate this Agreement;
     or
 
          (g) by mutual written consent of Zurich and Kemper.
 
     SECTION 7.2. Effect of Termination.  In the event of termination of this
Agreement by either Zurich or Kemper as provided in Section 7.1, this Agreement

3.8, 5.6 of the Kemper Merger Agreement (which is incorporated by reference

material breach of the representations, warranties, covenants or agreements set
forth in this Agreement.

at any time prior to the Effective Time, the parties hereto may modify or amend

the parties may (a) extend the time for the performance of any of the
obligations or other acts of the other parties, (b) waive any inaccuracies in
the representations and warranties of the other parties contained in this
Agreement or in any document delivered pursuant to this Agreement or (c) waive
compliance with any of the agreements or conditions of the other parties

extension or waiver shall be valid only if set forth in an instrument in writing
signed on behalf of such party. The failure of any party to this Agreement to
assert any of its rights under this Agreement or otherwise shall not constitute
a waiver of such rights.

to, this Agreement unless otherwise indicated. The table of contents and
headings contained in this Agreement are for reference purposes only and shall

     SECTION 8.6. Counterparts.  This Agreement may be executed in one or more
counterparts, all of which shall be considered one and the same agreement and
shall become effective when one or more counterparts have been signed by each of
the parties and delivered to the other parties.
 
     SECTION 8.7. Entire Agreement; Third-Party Beneficiaries.  This Agreement
(including the exhibits and Schedules attached hereto) and the other agreements
referred to herein (including, without limitation, the Kemper Merger Agreement)
constitute the entire agreement, and supersede all prior agreements and
understandings, both written and oral, among the parties with respect to the
subject matter of this Agreement. This Agreement is not intended to confer any
rights or remedies upon any person other than the parties hereto.
 
     SECTION 8.8. Governing Law.  This Agreement shall be governed by and
construed in accordance with the laws of the State of Delaware without regard to
conflicts of law principles thereof.
 
     SECTION 8.9. Assignment.  Neither this Agreement nor any of the rights,
interests or obligations under this Agreement shall be assigned, in whole or in
part, by operation of law or otherwise by any of the parties without the prior
written consent of the other parties, and any such assignment that is not
consented to shall be null and void; provided, however, that Zurich shall have

by motion or other request for leave from any such court and (c) agrees that it
will not bring any action relating to this Agreement or any of the transactions
contemplated by this Agreement in any court other than a court of the State of
Delaware or a federal court sitting in the State of Delaware.
 
     SECTION 8.11. Severability.  Whenever possible, each provision or portion
of any provision of this Agreement will be interpreted in such manner as to be
effective and valid under applicable law but if any provision or portion of any
provision of this Agreement is held to be invalid, illegal or
 
                                       21
<PAGE>   25
 
unenforceable in any respect under any applicable law or rule in any
jurisdiction, such invalidity, illegality or unenforceability will not affect
any other provision or portion of any provision in such jurisdiction, and this
Agreement will be reformed, construed and enforced in such jurisdiction as if
such invalid, illegal or unenforceable provision or portion of any provision had
never been contained herein.

          Kemper, Lumbermens and ZIP hereby agree that on the closing date of
     the Merger, (a) the Stock Exchange Agreement shall be amended by deleting
     Section 10.1 in its entirety (other than the definition of Lumbermens
     Businesses set forth in Section 10.1(a)(i)) and, without limitation,
     Zurich, Insurance Partners, Kemper and any of their respective Affiliates
     may, directly or indirectly (whether as principal, agent, independent
     contractor or otherwise) own, operate, control or otherwise carry on a
     business competitive with or substantially similar to any of the Lumbermens
     Businesses and (b) the Stock Exchange Agreement shall be amended by
     deleting Section 10.2 in its entirety (other than the definition of Kemper
     Businesses set forth in Section 10.2(a)(i)) and, without limitation,
     Lumbermens and any of its Affiliates may directly or indirectly (whether as
     principal, agent, independent contractor or otherwise) own, operate,
     control or otherwise carry on a business competitive with or substantially
     similar to any of the Kemper Businesses.
 
          2. Use of Kemper Name.  The parties hereto hereby agree that effective
     on the closing date of the Merger, Annex I of this letter agreement and the
     provisions set forth therein shall be
 
                                        1
<PAGE>   2
 
     binding upon and inure to the benefit of the parties hereto as if set forth
     in full in this letter agreement.
 
          3. Rejected Investment Portfolio Assets.  (a) Reference is made to
     Section 11.1(f) of the Stock Exchange Agreement, pursuant to which
     Lumbermens and Kemper agreed to the payment on the Final Settlement Date of
     the Final Settlement Amount with respect to the Rejected Assets.
     Lumbermens, Kemper and ZIP hereby agree that on the closing date of the
     Merger, Section 11.1(f)(z) of the Stock Exchange Agreement shall be amended
     to read as follows:
 
        "(z) if the Final Settlement Amount is negative, then Lumbermens shall
        deliver to Kemper the absolute value of the Final Settlement Amount by
        either (i) wire transfer of immediately available funds or (ii) if
        Lumbermens owns any shares of Kemper Common Stock on the Final
        Settlement Date, (x) delivering to Kemper a number of shares of Kemper
        Common Stock equal to the absolute value of the Final Settlement Amount
        divided by the Price Per Share or (y) delivering to Kemper a combination
        of cash and shares of Kemper Common Stock sufficient to satisfy the
        absolute value of the Final Settlement Amount. Notwithstanding anything
        in the preceding sentence to the contrary, the amount of cash delivered
        by Lumbermens pursuant to the preceding sentence shall not result in a
        Cash Limitation Fraction of 20 percent or more."
 
          (b) Notwithstanding anything to the contrary set forth in Section
     11.1(f) of the Stock Exchange Agreement, immediately prior to the filing of
     the certificate of merger on the closing date of the Merger (i) Lumbermens
     may deliver to Kemper an aggregate number of shares of Kemper Common Stock
     (the "Prepayment Shares") not greater than the number obtained by dividing
     (x) the Pre-Tax Gain on the sale of any one Rejected Asset by (y) the
     Prepayment Price Per Share (as hereinafter defined) and (ii) the Interim
     Period Amount for the Interim Period in which the Prepayment Shares are
     delivered shall be reduced as of the date such shares are delivered by an
     amount equal to the product of (x) the number of Prepayment Shares
     multiplied by (y) the Prepayment Price Per Share; provided, however, that
     since Lumbermens may wish to deliver to Kemper the Prepayment Shares on a
     date prior to the expected closing date of the Merger (but after October 1,
     1995) (the "Earlier Interim Settlement Date"), (i) Zurich, Insurance
     Partners, ZIP and Lumbermens shall seek to obtain the consent of Kemper to
     the Earlier Interim Settlement Date and (ii) Kemper shall not unreasonably
     withhold its consent to the Earlier Interim Settlement Date if all material
     conditions to the closing of the Merger have been satisfied or waived on
     the Earlier Interim Settlement Date. If Lumbermens delivers to Kemper the
     Prepayment Shares (i) immediately prior to the filing of the certificate of
     merger on the closing date of the Merger, then the Prepayment Price Per
     Share shall be the Merger Consideration (as defined in the Agreement and
     Plan of Merger among Zurich, Insurance Partners, ZIP and Kemper) or (ii) on
     the Earlier Interim Settlement Date, then the Prepayment Price Per Share
     shall be the arithmetical average of the last reported sale price of Kemper
     Common Stock on the New York Stock Exchange for the twenty (20) business
     days preceding the Earlier Interim Settlement Date.
 
          (c) If (i) Lumbermens elects to deliver to Kemper the Prepayment
     Shares as described in subparagraph (b) of this paragraph 3, Lumbermens
     hereby agrees to deliver to ZIP, Zurich and Insurance Partners prior to the
     record date of the Merger written notice of such election and (ii)
     Lumbermens fails to deliver such written notice prior to the record date of
     the Merger, paragraph 3(b) shall terminate and Lumbermens shall have no
     rights thereunder. Zurich, Insurance Partners and ZIP hereby agree to
     deliver at least ten (10) days prior written notice to Lumbermens of the
     record date of the Merger.
 
          (d) Notwithstanding anything to the contrary set forth in Section
     11.1(f) of the Stock Exchange Agreement or in this letter agreement, if (i)
     the Merger is consummated, (ii) the Final Settlement Amount is positive and
     (iii) Kemper Financial Services, Inc. ("KFS") is not a majority-owned
     subsidiary of Kemper on the Final Settlement Date, then to the extent that
     Kemper fails to
 
                                        2
<PAGE>   3
 
     pay to Kemper Reinsurance Company ("KRE") any portion of the Final
     Settlement Amount when due, KFS hereby agrees to pay to KRE, within thirty
     (30) days of the Final Settlement Date, such deficiency, plus any interest
     accrued thereon since the Final Settlement Date.
 
          4. Appraisal Rights; Series C Preferred Stock.  (a) On the date
     hereof, Lumbermens is the holder of all of the issued and outstanding
     shares of Series C Cumulative Preferred Stock, without par value, of Kemper
     (the "Series C Preferred Stock"). Lumbermens hereby agrees and confirms
     that it shall not (i) demand an appraisal of such shares of Series C
     Preferred Stock in connection with the Merger in accordance with Section
     262 of the General Corporation Law of the State of Delaware or (ii)
     transfer or otherwise dispose of such shares without an undertaking from
     such transferee to comply with clauses (i) and (ii) of this paragraph 4(a).
 
          (b) Kemper hereby agrees that after the closing date of the Merger,
     upon thirty (30) days prior written notice from Lumbermens to Kemper, which
     notice may be given not later than ninety (90) days after the occurrence of
     any event specified in clauses (i)-(iii) below, following the earlier to
     occur of (i) a 180-day period during which either (x) at least two of
     Standard & Poor's Ratings Group, Moody's Investors Services, Inc. and Duff
     & Phelps, Inc. or (y) the Securities Valuation Office of the National
     Association of Insurance Commissioners has continuously rated the Series C
     Preferred Stock below investment grade, (ii) the second separate time that
     the condition set forth in clause (i) above is satisfied without regard to
     the 180-day requirement or (iii) the first date (on or after April 1,
     1996), on which quarterly dividends on the Series C Preferred Stock have
     not been paid for two consecutive quarters, Kemper shall immediately
     purchase all of the Series C Preferred Stock owned by Lumbermens at a price
     per share of Series C Preferred Stock equal to $50, plus the amount of all
     dividends accrued and unpaid thereon (the "Series C Preferred Stock
     Purchase Price"); provided, however, that if such quarterly dividends on
     the Series C Preferred Stock have not been paid for two consecutive
     quarters as provided in clause (iii) above, then the thirty-day notice
     period described above shall be reduced to ten (10) days; and provided,
     further, that if and to the extent that Kemper fails to purchase any
     portion of the Series C Preferred Stock when due pursuant to this paragraph
     4(b), Zurich hereby agrees to purchase (or to cause an affiliate of Zurich
     to purchase) from Lumbermens at the Series C Preferred Stock Purchase Price
     all of the Series C Preferred Stock not purchased by Kemper, such purchase
     to occur within five business days after the date on which the Series C
     Preferred Stock Purchase Price was payable by Kemper to Lumbermens.
     Lumbermens hereby agrees to give written notice to Kemper and Zurich ten
     (10) days prior to the initial submission of any request by Lumbermens, on
     and after the closing date of the Merger, to any rating agency, including,
     without limitation, the Securities Valuation Office, for a rating on the
     Series C Preferred Stock and to give prompt written notice to Kemper and
     Zurich of any rating received on the Series C Preferred Stock.
 
          (c) Lumbermens hereby agrees that after the closing date of the
     Merger, upon thirty (30) days written notice to Lumbermens, each of Zurich
     and Kemper shall have the right and option to purchase from Lumbermens and,
     if Zurich or Kemper, as the case may be, exercises such right, Lumbermens
     shall have the obligation to sell, all of the shares of Series C Preferred
     Stock owned by Lumbermens at a price per share equal to the Series C
     Preferred Stock Purchase Price.
 
          (d) Lumbermens hereby agrees that all shares of Series C Preferred
     Stock purchased by Zurich or Kemper, as the case may be, pursuant to this
     paragraph 4 shall be delivered free and clear of all pledges, claims,
     liens, charges, encumbrances and security interests of any kind or nature
     whatsoever (collectively, "Liens") and Lumbermens shall represent and
     warrant to Zurich or Kemper, as the case may be, that such shares of Series
     C Preferred Stock are being transferred free and clear of all Liens.
 
          5. Investment Management Services.  For a period of at least three
     years after the date upon which the acquisition of KFS by Zurich or an
     entity controlled by Zurich is consummated (the
 
                                        3
<PAGE>   4
 
     "Asset Management Sale") and subject to the Investment Advisers Act of
     1940, as amended (the "Advisers Act"), Lumbermens hereby expresses its
     intention to continue to engage KFS, including its subsidiaries, to
     provide, consistent with past practices, professional investment management
     services with respect to not less than 80% of the investment assets of
     Lumbermens (excluding benefit plan assets held in trust) managed by KFS or
     its subsidiaries as of the date hereof on terms and conditions and in
     accordance with definitive agreements mutually acceptable to Lumbermens,
     Zurich and KFS; provided, however, that (i) KFS and its subsidiaries shall
     perform such investment management services only in accordance with the
     investment instructions of Lumbermens and (ii) notwithstanding anything to
     the contrary set forth in this paragraph 5, nothing in this paragraph 5
     shall be construed to delegate to KFS or its subsidiaries any investment
     decision or other function required by the Advisers Act or other legal
     requirement to be exercised by Lumbermens. Lumbermens shall, and shall
     cause each of its Subsidiaries and Affiliates that is a party to an
     investment advisory or management contract with KFS or its subsidiaries to,
     consent to the "assignment" (as defined under the Advisers Act) of their
     respective investment advisory and management contracts upon the
     consummation of the Asset Management Sale. Zurich hereby agrees to notify
     Lumbermens of the closing date of the Asset Management Sale within two days
     thereafter.
 
          6. Kemper Center Building Lease.  Reference is made to Section 15.02
     of the Office Building Lease, dated as of September 1, 1991 (the "Lease"),
     by and between Lumbermens and Kemper. The acquisition of all of the issued
     and outstanding shares of common stock of Kemper by Zurich and Insurance
     Partners as contemplated by the Merger shall be deemed an assignment of the
     Lease. Lumbermens hereby consents to the assignment of the Lease as
     required by Section 15.02 thereof as a result of the Merger.
 
          7. Investment in KFS.  (a) The parties hereto hereby understand that
     in connection with the consummation of the Asset Management Sale and the
     Merger, Lumbermens presently intends, and Zurich presently intends for
     Lumbermens, to invest in KFS an aggregate amount of up to $100 million or
     such lesser amount as is necessary to purchase (i) either 9.9% of the
     shares of common stock of KFS or an amount of convertible preferred stock
     of KFS that is convertible into 9.9% of the shares of common stock of KFS
     and (ii) pro rata with Zurich, all other equity and debt securities
     purchased from KFS by Zurich (the "KFS Investment"). The parties hereto
     shall (i) seek to structure the KFS Investment, if and to the extent
     practicable, through an exchange or contribution of common stock of Kemper,
     the Series C Preferred Stock and/or other Kemper Corporation securities
     owned by Lumbermens and (ii) use reasonable efforts to make the KFS
     Investment a tax-efficient transaction for each of Kemper, KFS and
     Lumbermens that is also satisfactory to Zurich and Kemper from a tax
     perspective.
 
          (b) The parties hereto hereby agree that the terms and conditions
     relating to the KFS Investment shall be set forth in definitive agreements
     to be mutually agreed upon by Lumbermens, Zurich and KFS and that such
     definitive agreements shall provide, among other things, that (i)
     Lumbermens shall receive representation on the Board of Directors of KFS
     that is proportionate to Lumbermens' equity interest in KFS, but in any
     event, at least one individual designated by Lumbermens shall be elected to
     the Board of Directors of KFS, (ii) if Lumbermens purchases shares of
     common stock of KFS in the KFS Investment, the price per share of such
     common stock of KFS paid by Lumbermens shall not exceed the price per share
     of common stock of KFS paid by Zurich in connection with the Asset
     Management Sale, (iii) after the seventh anniversary of the closing date of
     the Asset Management Sale, Lumbermens shall have the right to make a
     written demand to KFS to register under the Securities Act of 1933, as
     amended, all of the shares of capital stock of KFS owned by Lumbermens and
     (iv) if Lumbermens makes the KFS Investment and KFS provides professional
     investment management services with respect to less than 50% of the
     investment assets of Lumbermens (excluding benefit plan assets held in
     trust), then Lumbermens hereby agrees that Zurich or, at the option of
     Zurich, KFS shall have the right to purchase from Lumbermens and, if Zurich
     or KFS, as the case may be, exercises such right,
 
                                        4
<PAGE>   5
 
     Lumbermens shall have the obligation to sell to Zurich or KFS, as the case
     may be, all of the KFS Investment at an aggregate purchase price equal to
     the fair market value thereof.
 
          (c) The parties hereto hereby agree that (i) promptly after the date
     hereof, Kemper shall cause KFS to permit Lumbermens to perform customary
     due diligence with respect to KFS, subject to the execution and delivery by
     Lumbermens of a confidentiality agreement, reasonably satisfactory to
     Kemper, KFS and Lumbermens, and (ii) if Lumbermens requests from Zurich
     information relating to its valuation of KFS (including information
     furnished to Zurich by its financial advisers), then (x) Zurich shall
     consider such request in its reasonable discretion and (y) if Zurich
     complies with such request, any information furnished to Lumbermens by
     Zurich shall be subject to the execution and delivery by Lumbermens of a
     confidentiality agreement, reasonably satisfactory to Zurich and
     Lumbermens. The confidentiality agreements referred to in this subparagraph
     (c) shall provide, among other things, that Lumbermens waives any reliance
     on any information furnished by Kemper, KFS, Zurich, their respective
     Affiliates and Subsidiaries and their respective financial advisers and any
     liability of Kemper, KFS, Zurich, their respective Affiliates and
     Subsidiaries and their respective financial advisers arising out of such
     information so furnished.
 
          (d) The parties hereto hereby understand that if definitive agreements
     relating to the KFS Investment have not been executed within ninety (90)
     days after the date hereof or by such later date to which Zurich may
     consent in writing, which consent shall not be unreasonably withheld, then
     none of the parties hereto shall have any obligations under this paragraph
     7.
 
          8. Agreement on Arbella Tax Issue.  Lumbermens agrees that if (i)
     American Motorists Insurance Company ("AMICO") is entitled, as a result of
     its 1988 payment to Arbella Mutual Insurance Company in the amount of
     $17.85 million, to any deductions, credits, or offsets to income or gains
     in periods beginning after March 31, 1989, and (ii) AMICO, or any other
     member of the Lumbermens Group realizes any tax benefit in any taxable year
     (including, but not limited to, by way of a carryback of any such
     deductions, credits, or offsets to income or gain to periods ending on or
     before March 31, 1989) as a result of such deductions, credits, or offsets
     to income or gain, then Lumbermens will pay Kemper an amount equal to such
     tax benefit, together with any related interest at the applicable rate
     under the Internal Revenue Code of 1986, as amended, or any corresponding
     provision of state or local tax law, as the case may be. Kemper agrees that
     if AMICO is assessed any additional taxes, interest or penalties as a
     result of adjustments to AMICO tax periods through March 31, 1989 relating
     to Arbella, Kemper will pay such additional amounts and will not seek
     recovery from AMICO.
 
          9. Kemper Open Golf Tournament.  Lumbermens hereby agrees to grant
     Kemper, consistent with recent past practice, arrangements and
     understandings, invitational and other related privileges with respect to
     the annual Kemper Open golf tournament.
 
          10. Termination of Other Agreements.  Effective on the closing date of
     the Merger, Lumbermens and Kemper hereby agree that each of (i) the Stock
     Rights Agreement, dated as of March 31, 1989, by and between Lumbermens and
     Kemper, as amended by First Amendment to Stock Rights Agreement, dated as
     of March 18, 1993 (the "Stock Rights Agreement") and (ii) the Sponsors'
     Agreement, dated as of April 1, 1991, by and among Lumbermens, Kemper and
     Kemper Risk Management Services, as amended by First Amendment to the
     Sponsors' Agreement, dated as of August 2, 1993 (the "Sponsors Agreement"),
     other than Article III thereof, shall terminate and be of no further force
     and effect and each of Lumbermens and Kemper shall unconditionally and
     irrevocably release, acquit and forever discharge the other, and each of
     Lumbermens' and Kemper's successors, agents, directors, officers,
     stockholders, employees, representatives, subsidiaries, affiliates and all
     persons acting by, through, under or in concert with any of them or any of
     them, from any and all covenants, agreements, obligations and guarantees
     arising out of the Stock Rights Agreement and the Sponsors Agreement (other
     than Article III thereof).

          11. Restructuring of the Master Limited Partnership.  Lumbermens and
     Kemper hereby agree to restructure KLMLP, L.P. (the "MLP"), and the
     ownership of all direct and indirect debt and/or equity real estate
     interests currently owned by the MLP, on the following terms and
     conditions:
 
             (a) Title to the real property described on Exhibit A attached
        hereto and made a part hereof as "Arbor Hills" shall be transferred to
        Lumbermens.
 
             (b) Title to the real property described on Exhibit A as
        "Riverside" shall be transferred to Lumbermens. Kemper and Lumbermens
        acknowledge and confirm that the Riverside property is encumbered by
        first and second priority mortgages held by The Prudential Insurance
        Company of America ("Prudential"), which mortgages (collectively, the
        "Riverside Mortgage") are cross-collateralized and cross-defaulted with
        first and second priority mortgages (the "Other Mortgages") held by
        Prudential on the properties described on Exhibit A as "Benicia," "Stone
        Road," "One Corporate Centre," "Tustin" and "One ADP Plaza." (Kemper and
        Lumbermens acknowledge and confirm that the original principal amount of
        the note secured by the second priority Riverside Mortgage, which note
        restates, amends and reduces the note secured by the first priority
        Riverside Mortgage (such notes, collectively, the "Riverside Note"), was
        $6,400,000.) Kemper and Lumbermens shall in good faith act diligently
        and use their best efforts (which best efforts shall not include the
        payment of money or, except as expressly set forth below, the incurring
        of any obligations or the giving of any guaranties) to cause Prudential
        to consent to the above-described transfer of title to Riverside (the
        "Riverside Transfer") and to amend the Riverside Mortgage and the Other
        Mortgages so that the Riverside Mortgage is no longer
        cross-collateralized and cross-defaulted as described above, which best
        efforts shall, in the case of Lumbermens, include, without limitation,
        agreeing, in consideration for Prudential's consenting to the Riverside
        Transfer and so amending the Riverside Mortgage, to (i) amend the
        Riverside Mortgage and the notes secured thereby so as to extend the
        maturity date of said notes to June 23, 2000, increase the interest rate
        payable under said notes to a fixed rate equal to one hundred and
        fifteen (115) "basis points" in excess of the interest rate on 5-year
        U.S. Treasury securities as of the date Lumbermens accepts a commitment
        letter from Prudential in which Prudential offers to amend the Riverside
        Mortgage and the Other Mortgages on the terms described in this
        paragraph 11(b), and provide for monthly payments of principal and
        interest on a 25-year amortization schedule, (ii) pay Prudential a fee
        equal to one-quarter of one percent ( 1/4%) of the outstanding principal
        amount of the note secured by the second priority Riverside Mortgage,
        (iii) pay Prudential's legal fees and expenses in connection with the
        above-described amendments to the Riverside Mortgage and the Other
        Mortgages, up to a maximum amount of $10,000 and (iv) personally
        guarantee the indebtedness evidenced by the Riverside Note on terms and
        conditions reasonably satisfactory to Prudential. Whether or not
        Lumbermens makes the election described in paragraph 11(q) with respect
        to Riverside, the properties covered by the Other Mortgages shall remain
        K Properties (as defined in paragraph 11(g)) and the Conveyance
        Transaction with respect to each such K Property shall be consummated in
        accordance with the terms of this paragraph 11; provided, however, that
        from and after the consummation of each such Conveyance Transaction,
        Kemper shall indemnify Lumbermens and its affiliates, and their
        successors and assigns, from and against any and all Losses and Expenses
        incurred by any of them in connection with or arising from any breach by
        Kemper or any of its affiliates of, or default or event of default
        committed by Kemper or any of its affiliates under, the Other Mortgages.
 
             (c) Title to the real properties described on Exhibit A as "Napa
        Valley Corporate Park -- Vacant Land" ("Napa Land") and "Napa Valley
        Corporate Park -- Buildings 3A and 3B" ("L Napa Buildings"; collectively
        with Napa Land, the "L Napa Property") shall be transferred to
        Lumbermens. The L Napa Buildings shall continue, after such transfer, to
        be encumbered by a first priority mortgage held by Kemper Investors Life
        Insurance Company
 
                                        6
<PAGE>   7
 
        ("KILICO") that secures a $2,900,000 non-recourse promissory note having
        a maturity date of May 1, 1996 and an interest rate of nine percent (9%)
        per annum, provided that Lumbermens and KILICO shall execute and deliver
        amendments to such note and mortgage extending said maturity date to
        January 1, 2002 and providing that interest shall accrue (with interest
        at the rate of nine percent (9%) per annum) to the extent there is
        insufficient cash flow from the L Napa Buildings to make the semi-annual
        interest payments currently required. The Napa Land shall continue,
        after such transfer, to be encumbered by a first priority mortgage held
        by KILICO that secures a non-recourse promissory note having an original
        amount of $6,100,000, a current outstanding principal amount of
        approximately $2,300,000 and a maturity date in December, 2002 and that
        currently bears interest at a rate of seven and one-half percent
        (7 1/2%) per annum, provided that Lumbermens and KILICO shall execute
        and deliver amendments to such note and mortgage providing that (i) the
        interest rate under such note shall be seven and one-half percent
        (7 1/2%) per annum, (ii) interest under such note shall be payable as
        set forth in the further provisions of this sentence and in all other
        events shall accrue (with interest at the rate of seven and one-half
        percent (7 1/2%) per annum), (iii) subject to clause (iv) of this
        sentence, until such note is paid in full, if all or a part of the Napa
        Land is sold to a third-party buyer, such mortgage shall be released
        from the property sold if Lumbermens pays to KILICO (or its successors
        and assigns) the lesser of (1) ninety percent (90%) of the net proceeds
        of such sale and (2) the total outstanding principal and accrued
        interest under such note, which lesser amount shall be applied first to
        accrued interest, and then to the outstanding principal, under such note
        and (iv) if the contemplated "Pan-Am Sat" sale is consummated, such
        mortgage shall be released from the land sold if the net proceeds of
        such sale are placed in escrow pursuant to an escrow agreement
        reasonably satisfactory to Kemper and Lumbermens that provides that such
        proceeds shall be used to construct the cul-de-sac and related
        improvements required by the terms of the contemplated Pan-Am Sat sale.
        The parties acknowledge and confirm that Napa Industrial Properties, the
        owner of the L Napa Property, currently owes money to Lumbermens and/or
        its affiliates, and to KFC Portfolio Corp. ("KFCPC"), pursuant to
        various unsecured promissory notes (the "Napa Valley Notes"). Kemper and
        Lumbermens agree that (i) from and after the transfers described in the
        first sentence of this paragraph, the Napa Valley Notes shall be secured
        by a second priority mortgage on the L Napa Property in favor of the
        holders of the Napa Valley Notes, which mortgage and notes shall be
        recourse to the L Napa Property only (subject to a non-recourse
        exception for fraud), shall be recorded simultaneously with such
        transfers and shall contain terms and provisions which are customary for
        second priority mortgages held by institutional lenders and which are
        reasonably agreed to by Kemper and Lumbermens, (ii) all payments
        received under such second priority mortgage shall be distributed pari
        passu to Lumbermens and KFCPC, (iii) all net proceeds of sales of the
        properties secured thereby shall, after all payments required under the
        applicable first priority mortgage (if still remaining) are made, be
        applied towards payment of the Napa Valley Notes in accordance with the
        foregoing clause (ii), (iv) no payments shall be made or due under such
        second priority mortgage and the Napa Valley Notes except pursuant to
        the foregoing clause (iii) and (v) if the first priority mortgage on the
        Napa Land is released from a portion of the Napa Land in accordance with
        the foregoing provisions of this paragraph 11(c), such second priority
        mortgage shall also be released from such land. Kemper acknowledges and
        confirms that the L Napa Property is part of a Kemper Project (as
        defined in that certain Agreement to Form Partnership dated as of March
        18, 1993 by and among Kemper, Lumbermens and certain affiliates of each,
        as amended (the "Formation Agreement")) and that, without limiting the
        further provisions of this paragraph 11(c), the indemnity made by Kemper
        to Lumbermens in Section 29(a) of the Formation Agreement with respect
        to such Kemper Project shall (subject to the last paragraph of Section
        29 of the Formation Agreement and the further provisions of this
        paragraph 11(c)) remain in effect after the transfers described in the
        first sentence of this paragraph 11(c) are made. Kemper and Lumbermens
        acknowledge and confirm that the
 
                                        7
<PAGE>   8
 
        indemnity given by each to the other in Sections 29 and 30 of the
        Formation Agreement shall remain in effect after the consummation of the
        transactions contemplated by this paragraph 11; provided, however, that
        (i) notwithstanding the last sentence of each of said Sections 29 and
        30, the party (the "Indemnitor") indemnifying the other (the
        "Indemnitee") in any particular instance shall not take any action to
        mitigate any Damages and Costs (as defined in the Formation Agreement)
        that could adversely affect the applicable property, or the operation,
        use or value thereof, without the Indemnitee's prior written consent,
        such consent not to be unreasonably withheld (Kemper and Lumbermens
        hereby agree that if such consent is unreasonably withheld, such
        indemnity shall no longer apply with respect to the applicable
        property); (ii) neither Kemper nor Lumbermens may assign its rights
        under such indemnity to a non-affiliated third party, and any such
        assignment shall be void and of no force and effect and (iii) the
        Indemnitee shall promptly notify the Indemnitor whenever it has reason
        to believe that a claim may be made under such indemnity.
 
             (d) Title to the real property described on Exhibit A as "Mason
        Industrial" shall be transferred to Lumbermens.
 
             (e) Title to the real property described on Exhibit A as "Rancho
        Regional" shall be transferred to Lumbermens free and clear of any
        mortgages, pledges and security interests (other than mortgages, pledges
        and security interests held by Lumbermens or any affiliate thereof), and
        Kemper shall take all actions necessary to cause such property to be
        unencumbered by any such mortgages. Simultaneously with such transfer,
        Kemper and Lumbermens (or their applicable affiliates) shall enter into
        an easement agreement (the "Easement Agreement"), on terms and
        conditions reasonably satisfactory to each, granting the owner of Rancho
        Regional the right to construct and maintain a billboard on the property
        known as "Palm Plaza" advertising the contemplated shopping center at
        Rancho Regional, which agreement shall provide that (i) such billboard
        must be, and the construction and maintenance of such billboard must be,
        in material compliance with all applicable leases, so-called "REA's" and
        "CC&R's" and zoning and other laws and governmental requirements, (ii)
        the owner of Rancho Regional shall pay all of the costs and expenses in
        connection with the construction and maintenance of such billboard,
        (iii) Lumbermens and such owner shall jointly and severally indemnify
        and hold harmless the owner of Palm Plaza and its successors and assigns
        from and against any and all Losses and Expenses incurred by any of them
        in connection with or arising from such construction and maintenance
        (provided that such obligation of Lumbermens shall not survive the sale
        or other transfer of Rancho Regional to an entity that is not an
        affiliate of Lumbermens) and (iv) such billboard shall also advertise,
        in a manner (including, without limitation, size, location and
        character) reasonably satisfactory to the owner of Palm Plaza, the
        shopping center at Palm Plaza. The Easement Agreement shall also provide
        that (x) the owner of Palm Plaza, the owner of each other K Property (as
        defined in paragraph 11(g)) located in the "Mello-Roos" District and all
        other Kemper-controlled owners of property in such District
        (collectively with the owner of Palm Plaza and the owner of each other K
        Property in such District, the "Kemper Owners") shall, upon the written
        request of the owner of Rancho Regional, consent to or vote in favor of
        (to the extent such consent or such vote is requested or required by any
        applicable governmental authority) the construction by the owner of
        Rancho Regional of an overpass in the area designated therefor by the
        Village of Temecula and (y) if (1) the owner of Rancho Regional makes
        the above-described written request and (2) a so-called "regional
        shopping center" having at least three department store "anchor" tenants
        is not open for business at Rancho Regional as of the date the first
        payments on the bonds issued to finance construction of such overpass
        become due, Lumbermens and the owner of Rancho Regional shall, until
        such time as at least three such "anchor" tenants are open for business
        in such regional shopping center, jointly and severally indemnify and
        hold harmless the Kemper Owners and their successors and assigns from
        and against any and all Losses and Expenses (including, without
        limitation, any Losses due to special assessments assessed against Palm
        Plaza) incurred by
 
                                        8
<PAGE>   9
 
        any of them in connection with or arising from such overpass or the
        construction thereof (provided that such obligation of Lumbermens shall
        not survive the sale or other transfer of Rancho Regional to an entity
        that is not an affiliate of Lumbermens). Each of Kemper and Lumbermens
        shall diligently and in good faith endeavor to determine the most
        efficient technique, if any, to make the agreements set forth in the
        Easement Agreement binding on the successors and assigns of the
        applicable real property owners, and shall, if commercially reasonable
        to do so, implement such technique.
 
             (f) With respect to the real property described on Exhibit A as
        "Delta Wetlands," Kemper and Lumbermens acknowledge and confirm (i) the
        continuing obligation of KILICO and Lumbermens under the so-called "Term
        Loan B" to make (on a 50%/50% basis) advances totaling $19,177,473 to
        Delta Wetlands Properties, the owner of Delta Wetlands (the "Delta
        Owner") and (ii) their agreement to consummate transactions pursuant to
        which the so-called "equity loans" (the "Equity Loans") made by certain
        affiliates of Kemper and by Lumbermens and certain affiliates thereof
        shown on Exhibit B attached hereto and made a part hereof will be
        secured by a pledge of the MLP's partnership interest in the Delta Owner
        (Kemper and Lumbermens hereby agreeing that if, pursuant to the further
        provisions of this paragraph 11(f) and the provisions of paragraph
        11(m), the MLP's partnership interest in the Delta Owner is transferred
        to a new Kemper-Lumbermens joint venture, the Equity Loans will be
        secured by a pledge of such joint venture's partnership interest in the
        Delta Owner), and will no longer be secured by mortgages on any of the
        properties described on Exhibit A, including, without limitation, the
        property described on Exhibit A as "Hawaii Kai". From and after the date
        hereof, and notwithstanding any provisions to the contrary in the
        Formation Agreement or the Agreement of Limited Partnership of the
        Master Limited Partnership (the "MLP Partnership Agreement"), after all
        payments then due under the mortgage on Delta Wetlands that secures the
        so-called "Term Loan A" and "Term Loan B" are made (the "Delta
        Mortgage") (which payments shall be applied towards payment of Term Loan
        A and Term Loan B on a pari passu basis), all distributions made by the
        Delta Owner to the MLP (or its successor pursuant to the further
        provisions of the paragraph) shall first, be applied towards payment of
        the Equity Loans on a pari passu basis and then, be distributed by the
        MLP (or its successor) 75% to Kemper and/or affiliates thereof and 25%
        to Lumbermens and/or affiliates thereof. As explained in paragraph 11(m)
        below, it may be necessary to transfer the MLP's partnership interest in
        the Delta Owner to a newly-formed Kemper-Lumbermens joint venture. If
        such is the case, Kemper or an affiliate thereof shall hold 75% of the
        partnership interests in such joint venture and Lumbermens or an
        affiliate thereof shall hold 25% of the partnership interests in such
        joint venture. The terms and provisions of the joint venture agreement
        governing such new joint venture shall be diligently negotiated in good
        faith and reasonably agreed to by Kemper and Lumbermens, provided that
        such agreement (i) shall provide for the distributions described above
        and (ii) shall (notwithstanding the 75%-25% ownership structure
        described above) contain governance and management provisions
        substantially similar to the governance and management provisions
        contained in the Formation Agreement and the MLP Partnership Agreement
        (e.g., joint consent needed for all actions and decisions), except that
        Kemper and Lumbermens shall use reasonable efforts to agree on a dispute
        resolution procedure for the joint venture (or for the MLP, if the MLP
        shall continue to own its partnership interest in the Delta Owner after
        the consummation of the transactions contemplated by this paragraph 11).
 
             (g) Title to all real properties listed in Exhibit A and not
        addressed in the foregoing provisions of this paragraph 11, and all real
        properties and direct or indirect debt or equity interests in real
        estate and other assets not listed in Exhibit A that are owned by the
        MLP (the "Non-Exhibit A Properties"), shall be transferred to Kemper.
        The properties being transferred to Lumbermens pursuant to paragraphs
        11(a) through 11(e) above are hereinafter collectively referred to as
        the "L Properties," and all other properties listed on Exhibit A
 
                                        9
<PAGE>   10
 
        (other than Delta Wetlands), together with the Non-Exhibit A Properties,
        are hereinafter collectively referred to as the "K Properties."
 
             (h) Kemper and Lumbermens acknowledge and confirm that the
        respective ownership interests of affiliates of Kemper and affiliates of
        Lumbermens in the so-called "KRDC $75 Million Secured Loan" (the "KRDC
        Loan"), and the obligations of KRDC, Inc. in connection with the KRDC
        Loan shall, subject to the last sentence of this paragraph 11(h),
        continue to be governed by, inter alia, that certain Participation
        Agreement dated December 23, 1986 (the "Participation Agreement") and
        that certain KRDC Distribution Agreement dated October 1, 1994 (the
        "Distribution Agreement"), and that such ownership interests are as
        follows:
 
               KILICO: 20%
               Federal Kemper Life Assurance Company: 20%
               KFCPC: 20%
               AMICO: 20%
               KRE: 20%
 
        In addition, Kemper and Lumbermens acknowledge and confirm that subject
        to the further provisions of this paragraph 11(h), the Distribution
        Agreement, the Participation Agreement and the mortgages and pledges of
        notes and mortgages that secure the KRDC Loan shall remain in place
        after the consummation of the transactions contemplated by this
        paragraph 11. Notwithstanding any provision to the contrary in the
        Participation Agreement or any other document, AMICO and KRE (and their
        successors and assigns) shall, in connection with the sale by KRDC, Inc.
        to a third party of any of the properties covered by a mortgage securing
        said loan (but only if, in connection therewith, each of them receives
        from the net proceeds of such sale its pro rata share of the payment
        under said loan as required by the terms thereof, the Distribution
        Agreement and the Participation Agreement), consent to the discharge or
        reconveyance of such mortgage with respect to the property sold.
 
             (i) From and after January 1, 1995 (the "Effective Date"), (a) no
        monies derived from the operation and management of any L Property shall
        be used to fund any shortfall in connection with the operation and
        management of any K Property or Delta Wetlands, and (b) no monies
        derived from the operation and management of any K Property shall be
        used to fund any shortfall in connection with the operation and
        management of any L Property or Delta Wetlands. Kemper and Lumbermens
        shall promptly make the appropriate adjustments, in connection with
        funds provided during the period from and including the Effective Date
        until the date hereof by the owners of K Properties and L Properties to
        fund L Property, K Property or Delta Wetlands shortfalls, in order to
        cause compliance with the foregoing. Simultaneously with the
        consummation of the transactions described in paragraph 11(g), (i)
        Kemper shall pay Lumbermens an amount equal to all monies provided by
        Lumbermens and it affiliates from the Effective Date until the date of
        such consummation to fund shortfalls in connection with the operation
        and management of K Properties and (ii) Lumbermens shall pay Kemper an
        amount equal to all monies provided by Kemper and its affiliates from
        the Effective Date until the date of such consummation to fund
        shortfalls in connection with the operation and management of L
        Properties. Kemper and Lumbermens acknowledge and confirm that
        shortfalls in connection with the operation and management of L
        Properties from and including the Effective Date until and including
        April 30, 1995 (including, without limitation, shortfalls in connection
        with the operation and management of Kemper Real Estate Management
        Company ("KREMCO") that are allocated to the L Properties) were not more
        than $300,000.
 
             (j) Kemper and Lumbermens acknowledge and confirm that KREMCO's
        Board of Directors has approved certain "incentive bonuses" for KREMCO
        employees.

<PAGE>   11
 
             (k) Whenever in this paragraph 11 it is stated that title to a real
        property shall be transferred, such statement shall mean (i) a
        transaction (a "Conveyance Transaction") shall be consummated pursuant
        to which Kemper (or a designee or designees thereof) or Lumbermens (or a
        designee or designees thereof), as applicable, shall own 100% of the
        equity interests in such real property and in all personal property
        (including, without limitation, all accounts), intangible property and
        all other rights and interests (including, without limitation,
        development rights, but only to the extent transferable) relating to or
        used in connection with such real property or owned by the owner of such
        real property, (ii) except as expressly set forth above and in paragraph
        11(r) below, whichever of Kemper and Lumbermens is not the transferee in
        the Conveyance Transaction shall, prior to or simultaneously with such
        transaction, Eliminate (as defined in paragraph 11(m)) all indebtedness
        (and/or cause any applicable affiliates to Eliminate all indebtedness)
        payable by the owner of such property to it (and/or any affiliates) and
        discharge or reconvey (and/or cause any applicable affiliates to
        discharge or reconvey) any mortgage on such property held by it (and/or
        any affiliates), (iii) the Conveyance Transaction shall be evidenced by
        transfer documents which contain no representations or warranties,
        express or implied, other than representations by the transferor(s) that
        it (or they) has (or have) the authority to execute such documents and
        that it (or they) own the equity interests being transferred (as opposed
        to the underlying property) free and clear of all liens and pledges, and
        (iv) the parties shall execute and deliver all other documents necessary
        or desirable to consummate such Conveyance Transaction and the
        applicable transactions pursuant to clause (ii) of this sentence, which
        documents shall be on terms and conditions reasonably satisfactory to
        Kemper and Lumbermens. Except as expressly set forth in this paragraph
        11, from and after the consummation of a Conveyance Transaction, neither
        Kemper nor any affiliate thereof (if the transferee is Lumbermens), and
        neither Lumbermens nor any affiliate thereof (if the transferee is
        Kemper), shall have any liability in connection with (or shall have any
        property it owns serve as security for) any indebtedness of the owner of
        the applicable property. As of the date of a Conveyance Transaction with
        respect to which Lumbermens is the transferee, the applicable management
        agreement with KREMCO shall be terminated without penalty.
 
             (l) Kemper and Lumbermens acknowledge and confirm that certain
        third-party consents may be required in connection with certain
        Conveyance Transactions (including, without limitation, certain
        bondholder, bond issuer and governmental consents in connection with the
        contemplated Arbor Hill transfer). Kemper and Lumbermens agree that in
        connection with such consents, (i) the transferee under a Conveyance
        Transaction shall be responsible for obtaining all required consents;
        (ii) subject to the provisions of paragraph 11(q) below, each Conveyance
        Transaction shall be consummated in accordance with the terms and
        provisions hereof, regardless of the status of the obtaining of any
        required third-party consents; provided, however, that under no
        circumstances shall the Riverside Transfer be consummated if the consent
        of Prudential described in paragraph 11(b) is not obtained; and (iii)
        the party hereto that is not the transferee under a Conveyance
        Transaction (and all affiliates thereof) shall have no liability in
        connection with the failure to obtain any required third-party consents,
        and the transferee shall indemnify and hold harmless the other party
        hereto, its affiliates and their successors and assigns from and against
        all Losses and Expenses incurred by any of them in connection with or
        arising from such failure. Each of Kemper and Lumbermens shall execute
        such documents and take such actions (or shall cause its applicable
        affiliates to execute such documents and take such actions) as are
        reasonably requested by the other in connection with the obtaining of
        any such third-party consents.
 
             (m) Kemper and Lumbermens shall determine the manner in which each
        Conveyance Transaction, each Elimination of indebtedness and mortgage
        discharge or reconveyance to be consummated prior to or simultaneously
        with each Conveyance Transaction pursuant to clause (ii) of the first
        sentence of paragraph 11(k) above, each transaction to be accom-
 
                                       11
<PAGE>   12
 
        plished prior to or simultaneously with any Conveyance Transaction
        pursuant to paragraph 11(u), and each transaction to be accomplished
        pursuant to paragraph 11(o), shall be accomplished (such determinations
        being hereinafter collectively referred to as the "Method of Transfer
        Determination"). Without limiting the foregoing, (i) a Conveyance
        Transaction may be accomplished by means of a deed (which may be a
        deed-in-lieu of foreclosure or a deed given in exchange for the release,
        discharge or cancellation of indebtedness or as a partnership
        distribution), by means of a transfer of all the partnership interests
        in the owner of the applicable property, or (with respect to the
        Conveyance Transactions pursuant to paragraph 11(g)) by means of a
        transfer by Lumbermens and affiliates thereof of all of their
        partnership interests in the MLP and (ii) to "Eliminate" indebtedness
        means to consummate transactions pursuant to which such indebtedness is
        no longer payable by the owner of the applicable K Property or L
        Property and, if applicable, is no longer secured by a mortgage on such
        property, which transactions may include, but not be limited to, a
        cancellation of the applicable note, an assumption of such note by
        Kemper or an affiliate thereof (in the case of an L Property) or by
        Lumbermens or an affiliate thereof (in the case of a K Property), or an
        assumption of such note by the MLP (in which case, except to the extent
        specifically provided for herein, there shall be no recourse to any
        assets of Kemper or any affiliate thereof (in the case of a K Property)
        or to any assets of Lumbermens or any affiliate thereof (in the case of
        an L Property) in connection with such indebtedness). If Kemper and
        Lumbermens agree that the Conveyance Transactions pursuant to paragraph
        11(g) are to be accomplished by means of a transfer by Lumbermens and
        affiliates thereof of all of their partnership interests in the MLP,
        then (x) the partnership interest of the MLP in the Delta Owner shall be
        transferred to a new Kemper-Lumbermens joint venture as contemplated by
        paragraph 11(f), and (y) the properties as to which Lumbermens makes the
        election described in paragraph 11(q) below (or the equity interests in
        the entities that currently own such properties) shall be transferred to
        a new Kemper-Lumbermens joint venture as contemplated by paragraph
        11(q). In making the Method of Transfer Determination, and in making all
        other decisions, and taking any action, contemplated by this paragraph
        11 (such decisions and actions being referred to herein as "Other
        Decisions and Actions"), Kemper and Lumbermens shall jointly consider
        transfer, income and other tax issues and any other relevant factors in
        order to make the transactions contemplated by this paragraph 11 tax-
        efficient for each of Kemper and Lumbermens. Kemper and Lumbermens
        acknowledge and confirm that the provisions of this paragraph 11 are
        binding notwithstanding the fact that the Method of Transfer
        Determination and the Other Decisions and Actions have not yet been
        made.
 
             (n) The transactions described in paragraphs 11(a) through 11(f)
        shall be consummated as soon as practicable. Subject to paragraph 11(o)
        below, the transactions described in paragraph 11(g) and the third
        sentence of paragraph 11(i) shall be consummated simultaneously with the
        closing of the Merger (or with the satisfaction of the Preliminary
        Closing Conditions on the Preliminary Closing Date (as such terms are
        defined in the Agreement and Plan of Merger described in Section 13
        below), if such satisfaction occurs prior to the closing of the Merger);
        provided, however, that Kemper shall have the right, in its sole and
        absolute discretion upon written notice to Lumbermens, to elect to have
        any such transaction consummated as soon as practicable.
 
             (o) If, any time after the date hereof, a transfer of title
        contemplated by this paragraph 11 has not yet been consummated, but
        Kemper (in the case of a K Property) or Lumbermens (in the case of an L
        Property) desires to sell the property in question (or any equity
        interests therein), the other party hereto shall go-along with such sale
        (and shall cause any applicable affiliates to go-along with such sale),
        and shall take all actions and execute all documents (and shall cause
        any applicable affiliates to take all actions and execute all documents)
        (which actions may include, without limitation, the giving of consents,
        the discharge or reconveyance of mortgages and the Elimination of the
        indebted-

        ness secured thereby) reasonably requested by Kemper or Lumbermens, as
        applicable, in order to cause such sale to be consummated; provided,
        however, that under no circumstances shall Lumbermens or any affiliate
        thereof (in the case of a K Property), or Kemper or any affiliate
        thereof (in the case of an L Property), be required to incur any
        personal liability pursuant to any such document, unless (i) such
        personal liability is in connection with (x) a representation and
        warranty stating that the stock and/or partnership interests of
        Lumbermens and/or its applicable affiliates (in the case of a K
        Property) or Kemper and/or its affiliates (in the case of an L Property)
        in the property being transferred are owned free and clear of all liens
        and pledges or (y) a representation and warranty concerning Lumbermens'
        (and/or its applicable affiliates') authority to execute and deliver any
        documents necessary for such sale (including, without limitation, the
        purchase and sale agreement in connection therewith (Lumbermens hereby
        acknowledging that it understands that it is Kemper's intent that each
        such purchase and sale agreement provide that the seller thereunder
        shall not be obligated to consummate such sale unless and until either
        (i) the Merger is consummated or (ii) the Preliminary Closing Conditions
        are satisfied or waived on the Preliminary Closing Date)), or (ii) the
        other party hereto indemnifies and hold harmless such party or such
        party's affiliate, and the successors and assigns of such party or such
        party's affiliate, from and against any and all Losses and Expenses
        incurred in connection with or arising from such personal liability.
        Notwithstanding the provisions of the Formation Agreement and the MLP
        Partnership Agreement or the existence of any indebtedness payable by
        the owner of the property in question to Lumbermens or affiliates
        thereof (in the case of a K Property), or to Kemper or affiliates
        thereof (in the case of an L Property), all proceeds from the sale of a
        K Property shall be kept and/or distributed to Kemper and all proceeds
        from the sale of an L Property shall be kept and/or distributed to
        Lumbermens; provided, however, that such proceeds shall first be used
        (i) with respect to any L Property, to make required payments under the
        Distribution Agreement (if applicable) and under mortgages covering such
        property (or interests in such mortgages) held by Kemper and/or its
        affiliates which, pursuant to the terms hereof, are not to be discharged
        when the applicable Conveyance Transaction takes place and (ii) with
        respect to any K Property, to make required payments under the
        Distribution Agreement (if applicable) and under mortgages (or interests
        therein) covering such property held by Lumbermens and/or its affiliates
        which, pursuant to the terms hereof, are not to be discharged when the
        applicable Conveyance Transaction takes place. Without limiting the
        foregoing, Lumbermens acknowledges and confirms its consent to the
        transactions described in that certain Term Sheet attached hereto and
        made a part hereof as Exhibit C; provided, however, that Kemper and
        Lumbermens shall determine and negotiate with the third party the manner
        in which the transactions described in such Term Sheet shall be
        accomplished, taking into consideration transfer, income and other tax
        issues and any other relevant factors in order to make the transactions
        contemplated by such Term Sheet tax-efficient for each of Kemper and
        Lumbermens. The provisions of this paragraph 11(o) are subject to the
        penultimate sentence of paragraph 11(m).
 
             (p) Simultaneously with the transfer to Lumbermens of title to the
        last remaining L Property, Lumbermens shall transfer all of its capital
        stock in KREMCO to Kemper or a designee thereof for $10.00 of
        consideration. From and after the date hereof, Kemper shall fund 85% of
        all payments required to be made by KREMCO under that certain Term
        Promissory Note dated August 28, 1992, and Lumbermens shall fund 15% of
        such payments, which payments shall include payment, on the date that
        title to the last remaining L Property is transferred to Lumbermens, of
        all outstanding principal on and accrued interest under such note.
 
             (q) Notwithstanding any of the foregoing provisions of this
        paragraph 11, Lumbermens shall have the right, in its sole and absolute
        discretion on written notice to Kemper, to elect to not have an L
        Property transferred to it as contemplated above, provided that no such
        election can be made after December 31, 1995. If Lumbermens makes any
        such election,
 
                                       13
<PAGE>   14
 
        then (i) the applicable Conveyance Transaction, and any other
        transaction contemplated above relating to the applicable L Property,
        shall not take place and (ii) if, as explained in paragraph 11(m) above,
        it becomes necessary to transfer ownership of such L Property (or
        ownership of the equity interests in the entity that currently owns such
        L Property) to a newly-formed Kemper-Lumbermens joint venture, the terms
        and provisions of the joint venture agreement governing such new joint
        venture shall be diligently negotiated in good faith and reasonably
        agreed to by Kemper and Lumbermens, provided that such agreement shall
        (x) provide that Kemper (and/or certain of its affiliates) shall own 50%
        of the equity interests in such joint venture and Lumbermens (and/or
        certain of its affiliates) shall own 50% of the equity interests in such
        joint venture, (y) provide for distributions and allocations
        substantially similar to the distributions and allocations set forth in
        the MLP Agreement and (z) contain governance and management provisions
        substantially similar to the governance and management provisions
        contained in the Formation Agreement and the MLP Partnership Agreement
        (e.g., joint consent needed for all actions and decisions), except that
        Kemper and Lumbermens shall use reasonable efforts to agree on a dispute
        resolution procedure for the joint venture (or for the MLP, if it does
        not become necessary to transfer ownership of such L Property (or
        ownership of the equity interests in the entity that currently owns such
        L Property) to a newly formed Kemper-Lumbermens joint venture). From and
        after the date that Lumbermens makes any such election, the applicable L
        Property shall be deemed to not be an L Property, and shall not be
        deemed to be a K Property, for all purposes of this paragraph 11 (in
        which case, notwithstanding anything to the contrary contained herein,
        but subject to the proviso clause of this sentence, all debt payable to
        Kemper or Lumbermens or affiliates of either that is owed by the owner
        of such property and/or secured by a mortgage on such property shall
        remain in place and in effect); provided, however, that Lumbermens may,
        simultaneously with such election and in its sole and absolute
        discretion, also elect to have such L Property be deemed to be a K
        Property, which further election shall be binding and effective for all
        purposes of this paragraph 11.
 
             (r) Kemper and Lumbermens acknowledge and confirm (i) their
        agreement to consummate a transaction pursuant to which certain
        promissory notes (the "Hawaii Notes") described on Exhibit D attached
        hereto and made a part hereof as "Second Priority Loans" (which Hawaii
        Notes are held by Lumbermens, and affiliates of Kemper, in the
        percentages indicated on Exhibit D) will be secured by a third priority
        mortgage (the "Hawaii Mortgage") on the portion of Hawaii Kai known as
        "Bishop Estates Land" on terms and conditions reasonably satisfactory to
        Kemper and Lumbermens and (ii) that the rights of the holders of each
        Hawaii Note vis-a-vis the other Hawaii Notes and the notes described on
        Exhibit D as "First Priority Loans" are governed by that certain
        Intercreditor and Subordination Agreement Hawaii Kai (the "Hawaii
        Intercreditor Agreement") dated as of July 1, 1994 by and among
        Lumbermens and certain affiliates of Kemper. Notwithstanding paragraph
        11(k), the Hawaii Notes, the Hawaii Mortgage and the Hawaii
        Intercreditor Agreement shall remain in place and in effect after the
        consummation of the Conveyance Transaction with respect to Hawaii Kai.
 
             (s) The indemnifications made by Kemper and the indemnifications
        made by Lumbermens in this paragraph 11 shall be governed by the
        procedures set forth in Sections 13.3 and 13.4 of the Stock Exchange
        Agreement.
 
             (t) All references in this paragraph 11 to a mortgage shall mean a
        mortgage or a deed of trust, as applicable.
 
             (u) Kemper and Lumbermens acknowledge and confirm that Fidelity
        Life Association ("FLA") may have certain direct or indirect debt or
        equity interests in one or more of the L Properties, and that it is
        contemplated that as part of the transfer of title to any such L
        Property to Lumbermens, (i) any such equity interest of FLA shall be
        transferred to Lumbermens, and (ii) any debt as to which FLA has such an
        interest shall be treated in the
 
                                       14
<PAGE>   15
 
        manner set forth in clause (ii) of the first sentence of paragraph
        11(k). Towards that end, Kemper shall be responsible for obtaining FLA's
        agreement to consummate, on a timely basis, the transactions described
        in paragraphs 11 and 12 in which FLA is involved, including the PGA
        transaction, and otherwise cooperate in connection therewith, and Kemper
        shall indemnify and hold harmless Lumbermens and its successors and
        assigns from and against any and all Losses and Expenses incurred by any
        of them in connection with or arising from the failure to so obtain such
        agreement.
 
          12. Other Real Estate Related Matters.  (a) Kemper and Lumbermens
     shall diligently and in good faith attempt to reach agreement on certain
     issues pertaining to real estate related matters that are not addressed by
     paragraph 11 above but are the topic of ongoing discussions between Kemper
     and Lumbermens. These issues include, without limitation, the items listed
     on Annex II attached hereto. Kemper acknowledges and confirms its consent
     to the transaction with respect to the "PGA" property described on Exhibit
     A to Annex II to this letter agreement.
 
          (b) Notwithstanding anything to the contrary contained in this
     paragraph 12, each of Kemper and Lumbermens hereby expresses its good faith
     intention to cooperate with the other with respect to and not unreasonably
     withhold its consent to the transfer or other disposition by the other and
     the other's Affiliates of, or the write-down of debt on, any of the direct
     and indirect debt and equity real estate related interests of the other and
     the other's Affiliates.
 
          13. Term.  This letter agreement shall become effective upon the
     execution hereof and shall remain in full force and effect from and after
     such date; provided, however, that this letter agreement shall terminate
     and be of no further force and effect on the earlier to occur of (a) the
     date on which the Agreement and Plan of Merger among Zurich, Insurance
     Partners, ZIP and Kemper shall terminate without the Merger having been
     consummated and (b) June 30, 1996, if the Merger has not been consummated
     by such date.
 
          14. Notices.  All notices, requests, claims, demands and other
     communications under this letter agreement shall be in writing and shall be
     deemed given when delivered personally, upon receipt of a transmittal
     confirmation if sent by facsimile or like transmission, and upon receipt of
     proof of delivery when sent by overnight mail or overnight courier to the

companies have signed definitive agreements pursuant to which Kemper
Corporation would be acquired in a merger transaction valued at more than $2.0
billion.

         The definitive agreements include certain modifications to the
agreement in principle announced on April 11, 1995. Kemper stockholders will,
under the terms of the revised agreements, receive consideration of $49.50 per
share, all in cash. Zurich is expected to own approximately 80 percent of
Kemper Corporation, which will consist of its life insurance and real estate

connection with the merger, Zurich Insurance will acquire Kemper Financial
Services (KFS), a leading asset manager with approximately $62 billion in
assets under management.

         In previously announced transaction, Kemper stockholders were to
receive $47.50 in cash and $2.00 in preferred stock.

         Prior to closing, Kemper will complete its previously announced ESOP
sale and related spin-off of its securities brokerage operations. Including the
estimated value of the spin-off, the total value to Kemper stockholders from
these transactions approximates $51.00 per share.

         The definitive agreement is not subject to any financing contingency.
It is, however, subject to, among other things, Kemper Corporation common
stockholder approvals, Kemper mutual fund boards and shareholder approvals,
regulatory approvals, confirmation of the securities brokerage spin-off and
other customary conditions. The transaction is expected to close early in the
fourth quarter of 1995, or, at the option of the Investor Group, in January
1996.

         Rolf Hueppi, chairman, president and chief executive officer of Zurich
Insurance, stated, "With the signing of a definitive agreement, a new era
begins for Kemper Corporation. Adding the financial strength and long term
commitment of Zurich to Kemper's valuable brand name and reputation for
creativity and service will enhance Kemper's position in the asset management
and life insurance industries. We couldn't be more excited about the future of
this dynamic business combination."

         David B. Mathis, chairman and chief executive officer of Kemper
Corporation, stated, "We are pleased with the definitive terms of the
transaction and the Kemper board of directors unanimously concluded that this
agreement is in the best interest of our stockholders. It is now our goal to
continue working toward the closing of this transaction in the most expeditious
manner possible.  The Zurich will be an excellent partner for Kemper."
