                          CHANGE-OF-CONTROL SUPPLEMENT
                      AND AMENDMENT TO EMPLOYMENT AGREEMENT

                                       FOR
                               J. BARRY GRISWELL

     THIS CHANGE OF CONTROL SUPPLEMENT and AMENDMENT TO EMPLOYMENT AGREEMENT
("Supplement and Amendment") dated as of October 19, 2000 (the "Supplement
Date") is made by and among Principal Mutual Holding Company, an Iowa mutual
holding company (together with all successors thereto, "Mutual"), Principal
Financial Group, Inc., an Iowa corporation, Principal Financial Services, an
Iowa corporation, and Principal Life Insurance Company, an Iowa corporation
(together with all successors thereto, "Life") (each of the foregoing referred
to individually as a "Company" or collectively as "Companies"), and J. BARRY
GRISWELL ("Executive").

                                    RECITALS

     The Companies have determined that it is in the best interests of the
Companies and their members, (and if, at the relevant time, any are stock
companies, their stockholders) to assure that the Companies will have the
continued service of Executive. The Companies also believe it is imperative to
reduce the distraction of Executive that would result from the personal
uncertainties caused by a pending or threatened change of control of Mutual, to
encourage Executive's full attention and dedication to the Companies, and to
provide Executive with compensation and benefits arrangements upon a change of
control which ensure that the expectations of Executive will be satisfied and
are competitive with those of similarly-situated businesses. This Supplement and
Amendment is intended to accomplish these objectives, and to amend Executive's
Employment Agreement with the Companies dated as of May 19,2000 (such agreement
as amended from time to time, and any successors thereto, the "Employment
Agreement") in order to coordinate it with certain provisions that apply in the
event of a Change of Control or Imminent Control Change.

                                      ARTICLE I.

                                 CERTAIN DEFINITIONS

     As used in this Supplement and Amendment, capitalized terms have the

except as indicated below:

     1.1 "Accrued LTIP Bonus" means the amount of any LTIP Bonus earned but
either) deferred or not paid on or prior to the Effective Date, Merger of
Equals Cessation Date, or Termination Date, as applicable.

     1.2 "Accrued Obligations" means, as of any date, the sum of Executive's
Accrued Base Salary, Accrued Annual Bonus, Accrued LTIP Bonus, any accrued but
unpaid paid time off, and any other amounts and benefits which are then due to
be paid or provided to Executive by the Company, but have not yet been paid or
provided (as applicable).

<PAGE>   7

     1.3 "Annual Performance Period" -- see Section 2.2(b).

     1.4 "Annualized Target LTIP Bonus" means, in respect of any Termination
Date, an amount, based on the most recently granted LTIP Award for which the
LTIP Performance Period has not expired or terminated (disregarding for this
purpose the premature termination of any LTIP Performance Period that occurred
on or after the Effective Date), calculated as follows:

          (a) If the most recently granted LTIP Award was granted under the
     1999 Long-Term Performance Plan, the projected target award (stated as a
     percentage of Base Salary) as calculated at the beginning of the three-year
     award cycle which Executive would have been entitled to receive with
     respect to such most recent allocation of performance units as if "Gain
     from Operations" and "Return on Equity" (as such terms are defined in the
     1999 Long-Term Performance Plan) targets had been met.

          (b) If the most recently granted LTIP Award was granted under a New
     LTIP under which consecutive LTIP Performance Periods end each 12 months,
     the Executive's LTIP Target Award with respect to such most recent grant.

          (c) If the most recently granted LTIP Award was granted under a New
     LTIP under which consecutive LTIP Performance Periods end more or less
     frequently than each 12 months, the Executive's LTIP Target Award with
     respect to such most recent grant, multiplied by a fraction, the numerator
     of which is 12 and the denominator of which is the number of whole months
     between payments of LTIP Bonuses.

          (d) If the Executive has no LTIP Awards outstanding with respect to
     which the LTIP Performance Period has not yet ended, the amount shall be
     zero.

     1.5 "Article" means, unless the context otherwise requires, an article of
this Supplement.

     Person, a "25% Owner"); or

          (b) the Mutual Incumbent Directors (determined using the Supplement
     Date as the baseline date) cease for any reason to constitute at least a
     majority of the Board; or

          (d) approval by the members of Mutual, if at the relevant time Mutual
     is a mutual life insurance holding company, or approval by the stockholders
     of Mutual, if at the relevant time Mutual is a stock company, of a plan or
     agreement for the sale or other disposition of all or substantially all of
     the consolidated assets of Mutual or a plan of liquidation of Mutual.

Notwithstanding the foregoing, a Change of Control shall not occur merely as a
result of (i) Demutualization, or (ii) an underwritten initial public offering
of common stock of Mutual as filed with the SEC, unless such initial public
offering results in any SEC Person becoming a 25% Owner. Notwithstanding the
occurrence of any of the foregoing events, a Change of Control shall not occur

     Securities of the Surviving Corporation representing the stated
     percentage of the combined voting power of the then outstanding Voting
     Securities of the Surviving Corporation, in substantially the same
     respective proportions as such Person's ownership of Voting Securities of
     Mutual immediately before such Reorganization Transaction, and

          (b) if at the relevant time Mutual is a stock company, the Persons who
     were the direct or indirect owners of the outstanding common stock and
     Voting Securities of Mutual immediately before such Reorganization
     Transaction became, immediately after the consummation of such
     Reorganization Transaction, the direct or indirect owners of both the
     stated percentage of the then-outstanding common stock of the Surviving
     Corporation and Voting Securities representing the stated percentage of the
     combined voting power of the then-outstanding Voting Securities of the
     Surviving Corporation, in

     stock or restricted stock units and similar awards ("Restricted Shares").
     Notwithstanding the foregoing, if the Effective Date is a Reorganization
     Transaction and if so provided under the agreement pursuant to which the
     Reorganization Transaction is effected, then all Executive Stock Options
     shall (x) be extinguished for such consideration as is provided for vested
     options under such agreement or (y) be converted into options to purchase
     the stock of the Surviving Corporation, and such converted options shall be

                                      -12-

     subject to the same option terms and restrictions as those applicable on
     the Effective Date.

          (b) Merger of Equals. Section 2.3(a) shall not apply in the case of a
     Merger of Equals unless there occurs a Merger of Equals Cessation Date, at
     which time Section 2.3(a) shall be applied by substituting the Merger of
     Equals Cessation Date for the Effective Date wherever such term appears.

          (c) Imminent Control Change Period. Section 2.3(a) and (b) shall not
     apply during an Imminent Control Change Period.

     2.4 Unfunded Deferred Compensation.

          (a) Change of Control that is not a Merger of Equals. On the Effective
     Date, except as provided in Section 2.4(b) or (c) below, Executive shall
     become fully vested in all benefits previously accrued under any deferred
     compensation Plan (including a SERP and any defined contribution excess
     plan) that is not qualified under Section 401(a) of the Code. To the
     extent not so provided under such non-qualified plan, within ten business
     days after the Effective Date, the Company shall pay or cause to be paid to
     Executive a lump-sum cash amount equal to:

               (i) the sum of the Lump-Sum Values of all Maximum Annuities that
          are payable pursuant to all such non-qualified plans that are defined
          benefit Plans, plus

               (ii) the sum of Executive's account balances under all such non-
          qualified plans that are defined contribution Plans.

          (b) Merger of Equals. Section 2.4(a) shall not apply in the case of a
     Merger of Equals unless there occurs a Merger of Equals Cessation Date, at

     Equals Cessation Date for the Effective Date wherever such term appears.

          (c) Imminent Control Change Period. Section 2.4(a) and (b) shall not
     apply during an Imminent Control Change Period.

Executive shall have the opportunity to waive the accelerated vesting and
lump-sum payment at any time prior to the earlier of (i) the 15th day after the
date of an Imminent Control Change or (ii) the 30th day prior to a Change of
Control which is not preceded by an Imminent Control Change; provided, however,
that in no event shall the waiver be allowed on the Effective Date or
thereafter.

     2.5 Pro-rata Annual Bonus.

          (a) Change of Control that is not a Merger of Equals. Except as
     provided in Section 2.5(b) or (c) below, to the extent not so provided by
     the Bonus Plan, the Company shall pay or cause to be paid to Executive
     within ten business days after the Effective Date, a lump-sum cash payment
     equal to the Pro-rata Annual Bonus, in

                                      -13-

     Merger of Equals unless there occurs a Merger of Equals Cessation Date, at
     which time Section 2.6(a) shall be applied by substituting the Merger of
     Equals Cessation Date for the Effective Date.

          (c) Imminent Control Change Period. Section 2.6(a) and (b) shall not
     apply during an Imminent Control Change Period.

                                  ARTICLE III.

                            TERMINATION OF EMPLOYMENT

     3.1 Disability. The provisions of this Section 3.1 and Section 4.8 shall
supersede the provisions of Section 1.17 of the Employment Agreement (definition
of "Disability") and Section 6.2 of the Employment Agreement (Termination for
Retirement, Death or Disability) during the Post-Change Employment Period or any
Imminent Control Change Period but only insofar as such Section 6.2 applies to
termination for Disability.

          (a) During the Post-Change Employment Period or any Imminent Control
     Change Period, the Company may terminate Executive's employment at any time
     because of Executive's Disability by giving Executive or his legal
     representative, as applicable, (i) written notice in accordance with
     Section 9.7 of the Company's intention to terminate Executive's employment
     pursuant to this Section and (ii) a certification of Executive's Disability
     by a physician selected by the Company or its insurers, subject to the
     consent of Executive or Executive's legal representative, which consent
     shall not be unreasonably withheld or delayed. Executive's employment shall
     terminate effective on the 30th day after Executive's receipt of such
     notice (which such 30th day shall be deemed to be the date of the
     Disability) unless, before such 30th day, Executive shall have resumed the
     full-time performance of Executive's duties.

                                      -14-
<PAGE>   20

          (b) "Disability" means any medically determinable physical or mental
     impairment that has lasted for a continuous period of not less than six
     months and can be expected to be permanent or of indefinite duration, and
     that renders Executive unable to perform the duties required under this
     Supplement and Amendment.

     3.2 Death. Executive's employment shall terminate automatically upon
Executive's death during the Post-Change Employment Period or Imminent Control
Change Period.

     3.3 Termination for Cause.

          (a) Post-Change Employment Period. During the Post-Change Employment
     Period (including any portion thereof that qualifies as a Post-Merger of
     Equals Period), the Company may terminate Executive's employment for Cause
     solely in accordance with all of the substantive and procedural provisions
     of this Section 3.3(a). Section 1.11 of the Employment Agreement
     (definition of "Cause") and Section 6.1 of the Employment Agreement
     (Termination for Cause or Other than for Good Reason, etc.) shall be
     inapplicable during any Post-Change Employment Period, insofar as it
     relates to the material contained in this Section 3.3 and Section 4.6,
     except as otherwise provided herein.

               (i) Definition of Cause. For purposes of this section 3.3(a),
          "Cause" has the following meaning:

                    (1) Executive's conviction of, plea of guilty to, or plea of
               nolo contendere to a felony or misdemeanor (other than a
               traffic-related felony or misdemeanor) that involves fraud,
               dishonesty or moral turpitude;

                    (2) Executive's willful and intentional material misconduct
               in the performance or gross neglect of his duties that results in
               substantial financial detriment to a Company or any Affiliate;

                    (3) Executive's habitual neglect of duties (other than
               resulting from Executive's incapacity due to physical or mental
               illness other than habitual abuse of or addiction to alcohol or
               controlled substances) which results in substantial financial
               detriment to any of the Companies or any Affiliate; or

                    (4) Executive's willful and intentional material breach of
               the Employment Agreement or this Supplement and Amendment;

               provided, however, that for purposes of clauses (2), (3) and (4),
               Cause shall not include any one or more of the following:

                    (A) Executive's bad judgment

                    (B) Executive's negligence, other than Executive's habitual
               neglect of duties or gross negligence;

                                      -15-
<PAGE>   21
                    (C) any act or omission believed by Executive in good faith
               to have been in or not opposed to the interest of the Company
               (without intent of Executive to gain, directly or indirectly, a
               profit to which Executive was not legally entitled); or

                    (D) failure to meet performance goals, objectives or
               measures following good faith efforts to meet such goals,
               objectives or measures; and

          further provided that, if a breach of the Employment Agreement or this
          Supplement and Amendment involved an act, or a failure to act, which
          was done, or omitted to be done, by Executive in good faith and with a
          reasonable belief that Executive's act, or failure to act, was in the
          best interests of the Company or was required by applicable law or
          administrative regulation, such breach shall not constitute Cause if,
          within 30 days after Executive is given written notice of such breach
          that specifically refers to this Section, Executive cures such breach
          to the fullest extent that it is curable.

               (ii) Procedural Requirements for Termination for Cause. The
          Company shall strictly observe each of the following procedures:

                    (1) Board Meeting. A meeting of the Board shall be called
               for the stated purpose of determining whether Executive's acts or
               omissions constitute Cause and, if so, whether to terminate
               Executive's employment for Cause.

                    (2) Notice of Consideration, Not less than 30 days prior to
               the date of such meeting the Company shall provide Executive and
               each member of the Board written notice (a "Notice of
               Consideration") of (x) a detailed description of the acts or
               omissions alleged to constitute Cause, (y) the date, time and
               location of such meeting of the Board, and (z) Executive's rights
               under clause (3) below.

                    (3) Opportunity to Present Response. Executive shall have
               the opportunity with or without counsel, at Executive's election,
               an opportunity to be heard and present arguments and evidence on
               Executive's behalf at such a meeting and / or to present to the
               Board a written response to the Notice of Consideration.

                    (4) Cause Determination. Executive's employment may be
               terminated for Cause only if (x) the acts or omissions specified
               in the Notice of Consideration did in fact occur and do
               constitute Cause as defined in this Section, (y) the Board makes
               a specific determination to such effect and to the effect that
               Executive's employment should be terminated for Cause ("Cause
               Determination") and (z) the Company thereafter provides
               Executive with a Notice of Termination which specifies in
               specific detail the basis of such Termination of Employment for
               Cause and which Notice shall be consistent with the reasons set
               forth

                                      -16-
<PAGE>   22
               in the Notice of Consideration. The Cause Determination shall
               require the affirmative vote of at least 66-2/3% of the members
               of the Board.

          (b) Imminent Control Change Period. Except as provided below, this
     Section 3.3 shall not apply during any Imminent Control Change Period.
     Instead, the terms of Section 6.1 of the Employment Agreement shall govern
     a termination of Executive for Cause during an Imminent Control Change
     Period. However, in the case of an Imminent Control Change Period that
     culminates in a Consummation Date, no termination of Executive's employment
     during such Imminent Control Change Period shall be deemed to have been for
     Cause unless all the substantive and procedural provisions of Section
     3.3(b) shall have been satisfied:

               (i) Definition of Cause. For purposes of this Section 3.3(b),
          "Cause" shall have the meaning ascribed to it in Section 3.3(a).

               (ii) Procedural Requirements for Termination for Cause. To
          qualify as a termination for Cause, a termination by the Company
          during the Imminent Control Change Period shall have strictly complied
          with the procedures set forth in Section 3.3(a)(ii), substituting the
          phrase Imminent Control Change Period for Post-Change Employment
          Period wherever it appears.

          (c) Standard of Review. If the Notice of Consideration is given to
     Executive during an Imminent Control Change Period or a Post-Change
     Employment Period, then in the event that the existence of Cause shall
     become an issue in any action or proceeding between the Company and
     Executive, the Company shall, notwithstanding the Cause determination
     referenced in clause (4)(y) of Section 3.3(a)(ii), have the burden of
     establishing that the actions or omissions specified in the Notice of
     Consideration did in fact occur and do constitute Cause and that the
     Company has satisfied the procedural requirements of Section 3.3(a)(ii).

     3.4 Good Reason. During the Post-Change Employment Period (including any
portion thereof that is a Post-Merger of Equals Period), the Executive may
terminate his employment for Good Reason solely in accordance with all of the
substantive and procedural provisions of this Section 3.4. Section 1.21 of the
Employment Agreement (definition of "Good Reason") and Section 6.3 of the
Employment Agreement (Termination Without Cause or for Good Reason) shall be
inapplicable during any Post-Change Employment Period, insofar as it relates to
the material contained in this Section 3.4 and Article IV, except as otherwise
provided herein.

          (a) Change of Control and a Merger of Equals. During the Post-Change
     Employment Period (including any portion thereof that is a Merger of
     Equals), Executive may terminate his employment for Good Reason in
     accordance with the substantive and procedural provisions of this Section
     3.4(a).

               (i) Good Reason Definition. For purposes of this Section 3.4(a),
          "Good Reason" means the occurrence of any one or more of the following
          actions or omissions during the Post-Change Employment Period:

                    (1) any act or omission that would constitute Good Reason as
               defined in Section 1.21 of the Employment Agreement;

                                      -17-
<PAGE>   23
                    (2)  failure to pay Executive's Base Salary in violation of
               Section 2.2(a) or any failure to increase Executive's Base Salary
               to the extent, if any, required by such Section;

                    (3)  any failure to pay Executive's Annual Bonus or any
               reduction in Executive's bonus opportunity, in either case in
               violation of Section 2.2(b);

                    (4)  requiring Executive to be based at any office or
               location other than the location specified in Section 2.1(a);

                   (5) any other material breach of this Supplement and
               Amendment by the Company;

                    (6)  any Termination of Employment by the Company that
               purports to be for Cause, but is not in full compliance with all
               of the substantive and procedural requirements of this Supplement
               and Amendment (any such purported termination shall be treated as
               a Termination of Employment without Cause for all purposes of
               this Supplement and Amendment); or

                    (7)  the failure at any time of a successor to the Company
               explicitly to assume and agree to be bound by this Supplement and
               Amendment.

               (ii) Determination of Good Reason. Any reasonable determination
          by Executive that any of the events specified in subsection (i) above
          has occurred and constitutes Good Reason shall be conclusive and
          binding for all purposes, unless the Company establishes that
          Executive did not have any reasonable basis for such determination.

          (b)  Imminent Control Change Period. Except as provided below, this
     Section 3.4 shall not apply during any Imminent Control Change Period.
     Instead, the terms of Section 6.3 of the Employment Agreement (Termination
     Without Cause or for Good Reason) shall govern a termination by Executive
     for Good Reason during an Imminent Control Change Period. However, in the
     case of an Imminent Control Change Period that culminates in a Consummation
     Date, no termination of Executive's employment during such Imminent Control
     Change Period shall be deemed to have been for Good Reason unless all the
     substantive and procedural provisions of this Section 3.4(b) shall have
     been satisfied:

               (i)  Definition of Good Reason. For purposes of this Section
          3.4(b), "Good Reason" shall have the same meaning as in Section
          3,4(a)(i), except that the act or omission shall have occurred during
          the Imminent Control Change Period.

               (ii) Determination of Good Reason. Executive's determination that
          an event constituting Good Reason as defined in Section
          3.4(a)(i)(2)-(7) has occurred

                                      -18-

<PAGE>   24

          during an Imminent Control Change Period shall not be entitled to any
          presumptive validity or other deference by a court.

          (c)  Notice by Executive. In the event of any Termination of
     Employment by Executive for Good Reason during a Post-Change Employment
     Period (or during an Imminent Control Change Period if Executive intends to
     claim benefits hereunder in the event the Imminent Control Change Period
     culminates in a Consummation Date), Executive shall as soon as practicable
     thereafter notify the Company of the events constituting such Good Reason
     by a Notice of Termination. A delay in the delivery of such Notice of
     Termination or a failure by Executive to include in the Notice of
     Termination any fact or circumstance which contributes to a showing of Good
     Reason shall not waive any right of Executive under this Supplement and
     Amendment or preclude Executive from asserting such fact or circumstance in
     enforcing rights under this Supplement and Amendment; provided that no act
     or omission by the Company shall qualify as Good Reason if Executive's
     Termination of Employment occurs more than 12 months after Executive first
     obtains actual knowledge of such act or omission.

                                   ARTICLE IV.

        COMPANY'S OBLIGATIONS UPON CERTAIN TERMINATIONS OF EMPLOYMENT

     4.1 Termination During the Post-Change Employment Period. If, during the
Post-Change Employment Period (other than during a Post-Merger of Equals Period)
the Company terminates Executive's employment other than for Cause or
Disability, or Executive terminates employment for Good Reason, Section 6.3 of
the Employment Agreement (Termination Without Cause or For Good Reason) shall
not apply, and the Company's sole obligations to Executive under Articles II and
IV shall be as follows:

          (a) Severance Payments. The Company shall pay or provide Executive, in
     addition to all vested rights arising from Executive's employment as
     specified in Article II, a lump-sum cash amount equal to the sum of the
     following, no more than ten business days after the Termination Date:

               (i)  Accrued Obligations. All Accrued Obligations;

               (ii) Prorated Annual Bonus for Year of Termination. Executive's
          Pro-rata Annual Bonus reduced (but not below zero) by the amount of
          any Annual Bonus paid to Executive with respect to the Company's
          fiscal year in which the Termination Date occurs, whether paid under
          Section 2.5 or otherwise;

               (iii) Prorated LTIP Bonus. Executive's Pro-rata LTIP Bonus
          reduced (but not below zero) by the amount of any LTIP Bonus paid to
          Executive with respect to the LTIP Performance Periods not completed
          as of the Termination Date, whether such amount was paid under Section
          2.6 or otherwise;

               (iv)  Additional LTIP Amount. For each LTIP Performance Period
          that is unexpired as of the Date of Termination, Executive shall be
          treated as he would be treated under the LTIP in effect on the
          effective date of the Employment Agreement if (1) he terminated
          employment at age 57 other than for cause (as

                                      -19-
<PAGE>   25

          defined in the LTIP) and (2) he retired ("LTIP Benefit"); provided
          that the discretion of the Committee shall not be exercised so as to
          treat Executive less favorably than other members of Senior
          Management; provided further that if such payment cannot be provided
          under the terms of the LTIP or New LTIP, as applicable, then the
          Company shall pay amounts equal to such LTIP Benefit, reduced by
          amounts actually payable under the LTIP or New LTIP, as applicable, at
          the same time as they otherwise would have been paid;

               (v)  Deferred Pensions and Pension Enhancements. The sum of

                    (1)  all amounts previously deferred by, or accrued to the
               benefit of, Executive under any defined contribution
               non-qualified Plans (as described in Section 2.4), whether vested
               or unvested, together with any accrued earnings thereon, to the
               extent that such amounts and earnings have not been previously
               paid by the Company (whether pursuant to Section 2.4 or
               otherwise) or are provided under the terms of such non- qualified
               Plan; plus

                    (2)  an amount equal to the positive difference, if any,
               between:

                    (A)  the sum of the Lump-Sum Values of each Maximum Annuity
               that would be payable to Executive under any defined benefit Plan
               (whether or not qualified under Section 401(a)) if Executive had:

                              (1)  become fully vested in all such previously-
                              unvested benefits,

                              (2)  accrued a number of years of service (for
                              purposes of determining the amount of such
                              benefits, entitlement to early retirement
                              benefits, and all other purposes of such defined
                              benefit plans) that is three years greater than
                              the number of years of service actually accrued
                              by Executive as of the Termination Date, and

                              (3) received the lump-sum severance benefits
                              specified in Section 4.1(a) (excluding LTip
                              Bonuses and any amounts in respect of Stock
                              Options or Restricted Shares, if any, including
                              severance multiples thereof) as covered
                              compensation in equal monthly installments during
                              the period of three years following the
                              Termination Date, minus

                    (B)  the sum of(x) the Lump-Sum Values of the Maximum
               Annuity benefits actually payable to Executive under each defined
               benefit Plan that is qualified under Section 401(a) of the Code
               and (y) the

                                      -20-
<PAGE>   26

               aggregate amounts previously paid (whether pursuant to Section
               2.4 or otherwise) to Executive under the defined benefit Plans
               (whether or not qualified under Section 401(a) of the Code)
               described in clause (A) of this Section 4.1 (a)(v)(2).

               Notwithstanding the foregoing, the amount payable under this
               Section 4.1(a)(v)(2) with respect to the SERP and Principal
               Pension Plan for Employees in the aggregate, shall not be less
               than the amount to which Executive would be entitled as of the
               Date of Termination under Section 6.3(f) of the Employment
               Agreement (providing for certain benefits if the Date of
               Termination occurs prior to the Executive's 57th birthday).

               (vi) Multiple of Salary, Bonus and LTIP. An amount equal to three
          (3.0) times the sum of (x) Base Salary, (y) the Target Annual Bonus,
          and (z) the Annualized Target LTIP Bonus, each determined as of the
          Termination Date; provided, however, that any reduction in Executive's
          Base Salary or Annual Bonus that would qualify as Good Reason shall be
          disregarded for purposes of this clause (vi); and provided further,
          that the Annualized Target LTIP Bonus in clause (z) of this Section
          4.1(a)(vi) shall not be included in the sum referenced above if the
          Termination Date occurs on or after the third anniversary of the date
          the Company first makes a grant of stock options to a peer executive
          of the Company pursuant to a written employee stock option plan
          applicable to peer executives of the Company; and

               (vii) Unvested Defined Contribution Plan. To the extent not paid
          pursuant to Section 4.1(a)(v), an amount equal to the sum of the value
          of the unvested portion of Executive's accounts or accrued benefits
          under any unqualified or qualified defined contribution retirement
          plan maintained by the Company as of the Termination Date and
          forfeited by Executive by reason of the Termination of Employment.

          (b)  Continuation of Welfare and Fringe Benefits. Until the third
     anniversary of the Termination Date or such later date as any Plan may
     specify, the Company shall continue to provide to Executive and Executive's
     family welfare benefits (including medical, prescription, dental,
     disability, salary continuance, individual life, group life, accidental
     death and travel accident insurance plans and programs) and fringe benefits
     which are at least as favorable as the most favorable Plans of the Company
     applicable to members of Senior Management who are actively employed on the
     Termination Date and their families. The cost of such welfare benefits to
     Executive shall not exceed the cost of such benefits to actively employed
     members of Senior Management as applicable from time to time.

     If the Date of Termination occurs prior to the Executive's 57th birthday,
     Executive shall be entitled to the benefits equivalent to those payable
     under the Principal Welfare Benefit Plan for Employees calculated under the
     terms of such plan as if the Date of Termination occurred after Executive's
     57th birthday, reduced by amounts actually payable under such plan, and if
     either Executive or the Company reasonably believes it is likely that such

                                      -21-
<PAGE>   27

     benefits cannot be provided on a tax-favored basis, the Company shall pay
     the cost of the insurance premium for such benefits.

     Executive's rights under this Section shall be in addition to, and not in
     lieu of, any post-termination continuation coverage or conversion rights
     Executive may have pursuant to applicable law, including continuation
     coverage required by Section 4980 of the Code.

          (c)  Outplacement. The Company shall pay on behalf of Executive
     reasonable fees and costs charged by the outplacement firm selected by
     Executive to provide outplacement services to Executive after the
     Termination Date, within ten business days of its receipt of an invoice
     therefor, subject to a maximum of $30,000.

          (d)  Indemnification, Directors' and Officers' Liability Insurance.
     The provisions of Section 9.4 of the Employment Agreement (Indemnification
     and Insurance) shall continue to apply after the Effective Date.

          (e) Stock Incentive Awards. Immediately prior to the Executive's
     Termination of Employment, Executive shall (i) become fully vested in, and
     may thereafter exercise in whole or in part, in accordance with the terms
     thereof, all outstanding Stock Options and (ii) become fully vested in all
     Restricted Shares.

     4.2 Termination During a Post-Merger of Equals Period. If, during a
Post-Merger of Equals Period, the Company terminates Executive's employment
other than for Cause or Disability, or if Executive terminates employment for
Good Reason, Section 6.3 of the Employment Agreement (Termination Without Cause
or for Good Reason) shall not apply, and the Company's sole obligations to
Executive under Articles II and IV shall be as follows:

          (a) Severance Payments. The Company shall pay or provide Executive, in
     addition to all vested rights arising from Executive's employment as
     specified in Article II, a lump-sum cash amount, no more than thirty
     business days after the Termination Date, equal to the sum of all amounts
     described in Section 4.1(a).

          (b) Continuation of Welfare and Fringe Benefits. Until the third
     anniversary of the Termination Date or such later date as any Plan may
     specify, the Company shall continue to provide to Executive and Executive's
     family welfare benefits and fringe benefits with the same scope and cost as
     described in Section 4.1 (b).

     If the Date of Termination occurs prior to the Executive's 57th birthday,
     Executive shall be entitled to the benefits equivalent to those payable
     under the Principal Welfare Benefit Plan for Employees calculated under the
     terms of such plan as if the Date of Termination occurred after Executive's
     57th birthday, reduced by amounts actually payable under such plan, and if
     either Executive or the Company reasonably believes it is likely that such
     benefits cannot be provided on a tax-favored basis, the Company shall pay
     the cost of the insurance premium for such benefits.

     Executive's rights under this Section shall be in addition to, and not in
     lieu of, any post-termination continuation coverage or conversion rights
     Executive may have pursuant to applicable law, including continuation
     coverage required by Section 4980 of the Code.

                                      -22-
<PAGE>   28

          (c)  Outplacement. The Company shall pay on behalf of Executive
     reasonable fees and costs charged by the outplacement firm selected by the
     Company to provide outplacement services to Executive after the Termination
     Date, within ten business days of its receipt of an invoice therefor,
     subject to a maximum of $30,000.

          (d) Indemnification, Directors' and Officers' Liability Insurance The
     provisions of Section 9.4 of the Employment Agreement (Indemnification and
     Insurance) shall continue to apply during a Post-Merger of Equals Period.

          (e) Stock Incentive Awards. Immediately prior to Executive's
     Termination of Employment, Executive shall (i) become fully vested in, and
     may thereafter exercise in whole or in part, in accordance with the terms
     thereof, all outstanding Stock Options and (ii) become fully vested in all
     Restricted Shares.

     4.3 Termination During an Imminent Control Change Period (with no Change of
Control). If, during an Imminent Control Change Period, the Company terminates
Executive's employment other than for Disability and other than for a reason
that would constitute Cause if there were a Change of Control, or if Executive
terminates employment for a reason that would constitute Good Reason if there
were a Change of Control, and in either case the Imminent Control Change Period
does not culminate in a Consummation Date, the applicable terms of the
Employment Agreement shall govern, except that:

          (a)  Continuation of Welfare Benefits. Until the earlier of(i) the
     third anniversary of the Termination Date or (ii) the last day of the
     Imminent Control Change Period (or such later date as any Plan may
     specify), if it would provide greater benefits to Executive than under the
     Employment Agreement, the Company shall continue to provide to Executive
     and Executive's family welfare benefits with the same scope and cost as
     described in Section 6.3(d) of the Employment Agreement (Termination
     Without Cause or for Good Reason).

          (b)  Outplacement. The Company shall pay on behalf of Executive
     reasonable fees and costs charged by the outplacement firm selected by
     Executive to provide outplacement services to Executive after the
     Termination Date, within ten business days of its receipt of an invoice
     therefor, subject to a maximum of $30,000. All outplacement amounts payable
     on account of a Termination Date which occurred during an Imminent Control
     Change Period will be reduced (but not below zero) by outplacement amounts
     paid to Executive on account of such Termination Date but before payment
     pursuant to this Section 4.3(b).

          (c)  Stock Incentive Awards. In addition to vesting in accordance with
     Section 6.3(g) of the Employment Agreement, Executive's Stock Options
     (whether vested prior to or upon such Termination Date) will:

               (i)  not expire (unless such Stock Options would have so expired
          had Executive remained an employee of the Company) during the Imminent
          Control Change Period; and

                                      -23-
<PAGE>   29

               (ii) continue to be exercisable after the Termination Date to the
          extent provided in the applicable grant agreement or Plan, and
          thereafter, such Stock Options shall not be exercisable during the
          Imminent Control Change Period.

               Upon the date the Imminent Control Change lapses without a
               Consummation Date Executive's vested Stock Options may be
               exercised, in whole or in part, during the 30-day period
               following the lapse of the Imminent Control Change, (but in no
               case shall Stock Options remain exercisable after the date on
               which such Stock Options would have expired if Executive had
               remained an employee of the Company).

     4.4 Termination During an Imminent Control Change Period (which Culminates
in a Change of Control). If, during an Imminent Control Change Period that
culminates in a Consummation Date, the Company terminates Executive's employment
other than for Cause or Disability, or if Executive terminates employment for
Good Reason, the Employment Agreement shall govern prior to the Consummation
Date, and upon the Consummation Date the Company's sole obligations to Executive
under Articles II and IV shall be as follows:

          (a) Severance Payments. The Company shall pay or provide Executive, in
     addition to all vested rights arising from Executive's employment as
     specified in Article II, a lump-sum cash amount equal to the sum of all
     amounts described in Section 4.1(a). Such amount shall be paid no more
     than ten business days after an Effective Date that does not qualify as a
     Merger of Equals and no more than 30 business days after an Effective Date
     which does qualify as a Merger of Equals. Notwithstanding the foregoing,
     all amounts paid pursuant to this Section 4.4(a) shall be reduced (but not
     below zero) by the same or similar amounts paid to Executive on account of
     the Termination of Employment (under this Supplement and Amendment, the
     Employment Agreement, or otherwise), to the extent such amounts would
     reasonably be considered duplicative, prior to the date payment is made
     under this Section 4.4(a).

          (b) Continuation of Welfare Benefits. Until the third anniversary of
     the Termination Date or such later date as any Plan may specify, the
     Company shall continue to provide to Executive and Executive's family
     welfare benefits with the same scope and cost as described in Section
     4.1(b). Notwithstanding the foregoing, all coverage under this Section
     4.4(b) shall be reduced by all coverage provided by the Company to
     Executive on account of the Termination of Employment (under this
     Supplement and Amendment, the Employment Agreement, or otherwise), to the
     extent such amounts would reasonably be considered duplicative, prior to
     the date such benefits are provided under this Section 4.4(b).

     If the Date of Termination occurs prior to the Executive's 57th birthday,
     Executive shall be entitled to the benefits equivalent to those payable
     under the Principal Welfare Benefit Plan for Employees calculated under the
     terms of such plan as if the Date of Termination occurred after Executive's
     57th birthday, reduced by amounts actually payable under such plan, and if
     either Executive or the Company reasonably believes it is likely that such
     benefits cannot be provided on a tax-favored basis, the Company shall pay
     the cost of the insurance premium for such benefits.

                                      -24-
<PAGE>   30

     Executive's rights under this Section shall be in addition to, and not in
     lieu of, any post-termination continuation coverage or conversion rights
     Executive may have pursuant to applicable law, including continuation
     coverage required by Section 4980 of the Code.

          (c)  Outplacement. The Company shall pay on behalf of Executive
     reasonable fees and costs charged by the outplacement firm selected by
     Executive to provide outplacement services to Executive after the
     Termination Date, within ten business days of its receipt of an invoice
     therefor, subject to a maximum of $30,000. Notwithstanding the foregoing,
     all outplacement amounts payable pursuant to this Section 4.4(c) shall be
     reduced (but not below zero) by outplacement amounts paid to Executive on
     account of such Termination Date (under this Supplement and Amendment, the
     Employment Agreement, or otherwise) prior to the date payment is made under
     this Section 4.4(c).

          (d)  Stock Incentive Awards. In addition to vesting in accordance with
     Section 6.3(g) of the Employment Agreement, Executive's vested Stock
     Options (whether vested prior to or upon such Termination Date) shall be
     treated as follows:

               (i)  not expire (unless such Stock Options would have so expired
          had Executive remained an employee of the Company) during the Imminent
          Control Change Period; and

               (ii) continue to be exercisable after the Termination Date to the
          extent provided in the applicable grant agreement or Plan, and
          thereafter, such Stock Options shall not be exercisable during the
          Imminent Control Change Period.

               Upon the Consummation Date, such vested Stock Options may be
               exercised by Executive in whole or in part, during the 30-day
               period following the Consummation Date, (but in no case shall
               Stock Options remain exercisable after the date on which such
               Stock Options would have expired if Executive had remained an
               employee of the Company). Notwithstanding any provision in this
               Section, if the Consummation Date is a Reorganization
               Transaction, and if so provided under the agreement pursuant to
               which the Reorganization Transaction is effected, then all
               Executive's Stock Options shall (a) be extinguished for such
               consideration as is provided for vested options under such
               agreement; or (b) be converted into options to purchase the stock
               of the Surviving Corporation, and such converted options shall be
               subject to the same option terms as those applicable prior to the
               Consummation Date.

     4.5 Waiver and Release. Notwithstanding anything herein to the contrary,
the Company shall have no obligation to Executive under Section 4.1, 4.2, 4.3,
or 4.4 or Article V unless and until Executive executes a release and waiver of
Mutual and the Companies, in substantially the same form as attached hereto as
Exhibit A. This Section 4.5 shall supersede Section 6.5 of the Employment
Agreement (Waiver and Release) insofar as it relates to material contained in
this Section 4.5, effective on the Effective Date.

     4.6 Termination by the Company for Cause. If the Company terminates
Executive's employment for Cause during the Post-Change Employment Period or
Imminent Control Change Period, Section 6.1 of the Employment Agreement
(Termination for Cause or Other than for

                                      -25-
<PAGE>   31

Good Reason, etc.) shall not apply, and the Company's sole obligation to
Executive under Articles II and IV shall be to pay Executive a lump-sum cash
amount equal to all Accrued Obligations determined as of the Termination Date.
The LTIP Bonus shall be governed according to the terms of the LTIP and New
LTIP, as applicable.

     4.7 Termination by Executive Other Than for Good Reason.

          (a)  If Executive terminates employment during the Post-Change
     Employment Period or Imminent Control Change Period other than for
     Retirement, Good Reason, Disability or death, Section 6.2 of the Employment
     Agreement (Termination for Retirement, Death or Disability) shall not
     apply, and the Company's sole obligation to Executive under Articles II and
     IV shall be to pay Executive a lump-sum cash amount equal to all Accrued
     Obligations determined as of the Termination Date. The LTIP Bonus shall be
     governed according to the terms of the LTIP and New LTIP, as applicable.

          (b)  If Executive terminates employment during the Post-Change
     Employment Period or Imminent Control Change Period due to his Retirement,
     Section 6.2 of the Employment Agreement (Termination for Retirement, Death
     or Disability) shall govern.

     4.8 Termination by the Company for Disability. If the Company terminates
Executive's employment by reason of Executive's Disability during the
Post-Change Employment Period or Imminent Control Change Period, Section 6.2 of
the Employment Agreement (Termination for Retirement, Death or Disability) shall
not apply, and Company's sole obligation to Executive under Articles II and IV
shall be as follows:

          (a)  to pay Executive (i) the amount determined in accordance with
     Section 6.2 of the Employment Agreement (Termination for Retirement, Death
     or Disability), and (ii) to the extent not paid under the Employment
     Agreement, a lump-sum cash amount equal to all Accrued Obligations
     determined as of the Termination Date, and

          (b) to provide Executive disability and other benefits after the
     Termination Date that are not less than the most favorable of such benefits
     then available under Plans of the Company to disabled peer executives of
     the Company.

If the Termination Date occurred during an Imminent Control Change Period which
had a Consummation Date which is not also a Merger of Equals or a Post-Change
Employment Period other than a Post-Merger of Equals Period, such disability and
other benefits shall also be no less favorable, in the aggregate, than the most
favorable of the disability and other benefits available to Executive under such
Plans in effect at any time during the 90-day period immediately preceding (1)
the Effective Date if such Termination Date occurred during a Post-Change
Employment Period or (2) the date of the Imminent Control Change if such
Termination Date occurred during an Imminent Control Change Period. The LTIP
Bonus shall be governed according to the terms of the LTIP and New LTIP, as
applicable.

     4.9 If upon Death. If Executive's employment is terminated by reason of
Executive's death during the Post-Change Employment Period or Imminent Control
Change Period, Section 6.2 of the Employment Agreement (Termination for
Retirement, Death or Disability)

                                      -26-
<PAGE>   32

shall not apply, and the Company's sole obligations to Executive under Articles
II and IV shall be as follows:

          (a) to pay Executive's Beneficiary or estate (i) the amount determined
     in accordance with Section 6.2 of the Employment Agreement (Termination for
     Retirement, Death or Disability) and (ii) to the extent not paid under the
     Employment Agreement, a lump-sum cash amount equal to all Accrued
     Obligations; and

          (b) to provide Executive's estate or Beneficiary survivor and other
     benefits that are not less than the most favorable survivor and other
     benefits then available under Plans of the Company to the estates or the
     surviving families of peer executives of the Company.

If the Termination Date occurred during an Imminent Control Change which had a
Consummation Date which is not also a Merger of Equals or a Post-Change
Employment Period other than a Post-Merger of Equals Period, such survivor
benefits shall also be no less favorable, in the aggregate, than the most
favorable of the survivor benefits available to Executive under such Plans in
effect at any time during the go-day period immediately preceding (1) the
Effective Date if such Termination Date occurred during a Post-Change Employment
Period or (2) the date of the Imminent Control Change if such Termination Date
occurred during an Imminent Control Change Period. The LTIP Bonus shall be
governed according to the terms of the LTIP and New LTIP, as applicable.

     4.10 Executive's Election to Waive. Notwithstanding the foregoing
provisions of this Article IV or any provision of the Employment Agreement, if
Executive's employment is terminated during a Post-Change Employment Period
other than for Disability, or other than by the Company for Cause, including
under circumstances entitling Executive to payments and provision of benefits
under Section 4.1 or 4.2., then Executive may waive ("Severance Waiver") all his
rights to such payments and benefits, and all rights to payments and provision
of benefits under Section 6.3 of the Employment Agreement; provided, however
that the Severance Waiver shall not include a waiver of payment or provision of
Executive's Accrued Obligations. Any such Severance Waiver shall be in writing,
and shall be delivered to the Company as provided in Section 9.7 within three
days of such termination of employment (and in any event prior to Executive's
receipt of any payments or benefits). The provisions of Section 7.1 of the
Employment Agreement (Non-Competition) shall not apply from and after the date
the Severance Waiver is duly delivered to the Company.

                                   ARTICLE V.

                       CERTAIN ADDITIONAL PAYMENTS BY THE COMPANY

     5.1 Gross-Up Payment. During the Supplement Term, this Section 5.1 shall
supersede Section 8.1 of the Employment Agreement, effective on an Effective
Date. If at any time or from time to time, it shall be determined by the
Company's independent auditors, but only after an Effective Date, that any
payment or other benefit to Executive pursuant to Article II or Article IV of
this Supplement and Amendment or otherwise ("Potential Parachute Payment") is or
will become subject to the excise tax imposed by Section 4999 of the Code or any
similar tax payable under any United States federal, state, local, foreign or
other law ("Excise Taxes"), then the

                                      -27-
<PAGE>   33

Company shall pay or cause to be paid a tax gross-up payment ("Gross-Up
Payment") with respect to all such Excise Taxes and other Taxes on the Gross-Up
Payment. The Gross-Up Payment shall be an amount equal to the product of

          (a)  The amount of the Excise Taxes (calculated at the effective
     marginal rates of all federal, state, local, foreign or other law),

     multiplied by

          (b) A fraction (the "Gross-Up Multiple"), the numerator or which is
     one (1.0), and the denominator of which is one (1.0) minus the lesser
     of (i) the sum, expressed as a decimal fraction, of the effective marginal
     rates of any Taxes and any Excise Taxes applicable to the Gross-Up Payment
     or (ii) .80. If different rates of tax are applicable to various portions
     of a Gross-Up Payment, the weighted average of such rates shall be used.
     For purposes of this section, Executive shall be deemed to be subject to
     the highest effective marginal rate of Taxes.

The Gross-Up Payment is intended to compensate Executive for all such Excise
Taxes and any other Taxes payable by Executive with respect to the Gross-Up
Payment. The Company shall pay or cause to be paid the Gross-Up Payment to
Executive within ten (10) days of the calculation of such amount, but in no
event after the Executive is required to make payment to the IRS of such Excise
Taxes.

     5.2 Limitation on Gross-Up Payments. This Section 5.2 shall supersede
Section 8.2 of the Employment Agreement, effective on the Supplement Date.

          (a) To the extent possible, any payments or other benefits to
     Executive pursuant to Article II and Article IV of this Supplement and
     Amendment shall be allocated as consideration for Executive's entry into
     the covenants of Article VII of the Employment Agreement (Restrictive
     Covenants).

          (b) Notwithstanding any other provision of this Article V, if the
     aggregate After-Tax Amount (as defined below) of the Potential Parachute
     Payments and Gross-Up Payment that, but for this Section 5.2, would be
     payable to Executive, does not exceed 110% of After-Tax Floor Amount (as
     defined below), then no Gross-Up Payment shall be made to Executive and the
     aggregate amount of Potential Parachute Payments payable to Executive shall
     be reduced (but not below the Floor Amount) to the largest amount which
     would both (i) not cause any Excise Tax to be payable by Executive and (ii)
     not cause any Potential Parachute Payments to become nondeductible by the
     Company by reason of Section 280G of the Code (or any successor provision).
     For purposes of the preceding sentence, Executive shall be deemed to be
     subject to the highest effective marginal rate of Taxes.

          (c) For purposes of this Supplement and Amendment:

               (i)  "After-Tax Amount" means the portion of a specified amount
          that would remain after payment of all Taxes paid or payable by
          Executive in respect of such specified amount;

                                      -28-
<PAGE>   34

              (ii)  "Floor Amount" means the greatest pre-tax amount of
          Potential Parachute Payments that could be paid to Executive without
          causing Executive to become liable for any Excise Taxes in connection
          therewith; and

             (iii) "After-Tax Floor Amount" means the After-Tax Amount of the
          Floor Amount.

     5.3 Additional Gross-up Amounts. If for any reason (whether pursuant to
subsequently enacted provisions of the Code, final regulations or published
rulings of the IRS, or a final judgment of a court of competent jurisdiction)
the Company's independent auditors later determine that the amount of Excise
Taxes payable by Executive is greater than the amount initially determined
pursuant to Section 5.1, then the Company shall, subject to Sections 5.2 and
5.4, pay Executive, within ten (10) days of such determination, or pay to the
IRS as required by applicable law, an amount (which shall also be deemed a
Gross-Up Payment) equal to the product of:

          (a) the sum of (i) such additional Excise Taxes and (ii) any interest,
     penalties, expenses or other costs incurred by Executive as a result of
     having taken a position in accordance with a determination made pursuant to
     Section 5.1 or 5.4,

multiplied by

          (b) the Gross-Up Multiple.

     5.4 Amount Increased or Contested.

          (a) Executive shall notify the Company in writing (an "Executive's
     Notice") of any claim by the IRS or other taxing authority (an "IRS Claim")
     that, if successful, would require the payment by Executive of Excise Taxes
     in respect of Potential Parachute Payments in an amount in excess of the
     amount of such Excise Taxes determined in accordance with Section 5.1.
     Executive's Notice shall include the nature and amount of such IRS
     Claim, the date on which such IRS Claim is due to be paid (the "IRS Claim
     Deadline"), and a copy of all notices and other documents or correspondence
     received by Executive in respect of such IRS Claim. Executive shall give
     the Executive's Notice as soon as practicable, but no later than the
     earlier of (i) 10 days after Executive first obtains actual knowledge of
     such IRS Claim or (ii) five days before the IRS Claim Deadline; provided,
     however, that any failure to give such Executive's Notice shall affect the
     Company's obligations under this Article only to the extent that the
     Company is actually prejudiced by such failure. If at least one business
     day before the IRS Claim Deadline the Company shall:

               (i)  deliver to Executive a written certificate from the
          Company's independent auditors ("Company Certificate") to the effect
          that, notwithstanding the IRS Claim, the amount of Excise Taxes,
          interest or penalties payable by Executive is either zero or an amount
          less than the amount specified in the IRS Claim,

               (ii) pay to Executive, or to the IRS as required by applicable
          law, an amount (which shall also be deemed a Gross-Up Payment) equal
          to difference

                                      -29-
<PAGE>   35

          between the product of (x) amount of Excise Taxes, interest and
          penalties specified in the Company Certificate, if any, multiplied by
          (y) the Gross-Up Multiple, less the portion of such product, if any,
          previously paid to Executive by the Company, and

               (iii) direct Executive pursuant to Section 5.4(d) to contest the
          balance of the IRS Claim,

     then Executive shall pay only the amount, if any, of Excise Taxes, interest
     and penalties specified in the Company Certificate. In no event shall
     Executive pay an IRS Claim earlier than 30 days after having given an
     Executive's Notice to the Company (or, if sooner, the IRS Claim Deadline).

          (b) At any time after the payment by Executive of any amount of Excise
     Taxes, other Taxes or related interest or penalties in respect of Potential
     Parachute Payments (including any such amount equal to or less than the
     amount of such Excise Taxes specified in any Company Certificate, or IRS
     Claim), the Company may in its discretion require Executive to pursue a
     claim for a refund (a "Refund Claim") of all or any portion of such Excise
     Taxes, other Taxes, interest or penalties as may be specified by the
     Company in a written notice to Executive.

          (c) If the Company notifies Executive in writing that the Company
     desires Executive to contest an IRS Claim or to pursue a Refund Claim,
     Executive shall:

               (i)  give the Company all information that it reasonably requests
          in writing from time to time relating to such IRS Claim or Refund
          Claim, as applicable,

               (ii) take such action in connection with such IRS Claim or
          Refund Claim (as applicable) as the Company reasonably requests in
          writing from time to time, including accepting legal representation
          with respect thereto by an attorney selected by the Company, subject
          to the approval of Executive (which approval shall not be unreasonably
          withheld or delayed),

               (iii) cooperate with the Company in good faith to contest such
          IRS Claim or pursue such Refund Claim, as applicable,

               (iv)  permit the Company to participate in any proceedings
          relating to such IRS Claim or Refund Claim, as applicable, and

               (v)   contest such IRS Claim or prosecute Refund Claim (as
          applicable) to a determination before any administrative tribunal, in
          a court of initial jurisdiction and in one or more appellate courts,
          as the Company may from time to time determine in its discretion.

     The Company shall control all proceedings in connection with such IRS Claim
     or Refund Claim (as applicable) and in its discretion may cause Executive
     to pursue or forego any and all administrative appeals, proceedings,
     hearings and conferences with the Internal Revenue Service or other taxing
     authority in respect of such IRS Claim or Refund Claim

                                      -30-
<PAGE>   36

     (as applicable); provided that (i) any extension of the statute of
     limitations relating to payment of taxes for the taxable year of Executive
     relating to the IRS Claim is limited solely to such IRS Claim, (ii) the
     Company's control of the IRS Claim or Refund Claim (as applicable) shall be
     limited to issues with respect to which a Gross-Up Payment would be
     payable, and (iii) Executive shall be entitled to settle or contest, as the
     case may be, any other issue raised by the Internal Revenue Service or
     other taxing authority.

          (d) The Company may at any time in its discretion direct Executive to
     (i) contest the IRS Claim in any lawful manner or (ii) pay the amount
     specified in an IRS Claim and pursue a Refund Claim; provided, however,
     that if the Company directs Executive to pay an IRS Claim and pursue a
     Refund Claim, the Company shall advance the amount of such payment to
     Executive on an interest-free basis and shall indemnify Executive, on an
     after-tax basis, for any Excise Tax or income tax, including related
     interest or penalties, imposed with respect to such advance.

          (e) The Company shall pay directly all legal, accounting and other
     costs and expenses (including additional interest and penalties) incurred
     by the Company or Executive in connection with any IRS Claim or Refund
     Claim, as applicable, and shall indemnify Executive, on an after-tax basis,
     for any Excise Tax or income tax, including related interest and penalties,
     imposed as a result of such payment of costs and expenses.

     5.5 Refunds. If, after the receipt by Executive or the IRS of any payment
or advance of Excise Taxes or other Taxes by the Company pursuant to this
Article, Executive receives any refund with respect to such Excise Taxes,
Executive shall (subject to the Company's complying with any applicable
requirements of Section 5.4) promptly pay the Company the amount of such refund
(together with any interest paid or credited thereon after taxes applicable
thereto). If, after the receipt by Executive of an amount advanced by the
Company pursuant to Section 5.4, or receipt by the IRS of an amount paid by the
Company on behalf of the Executive pursuant to Section 5.4, a determination is
made that Executive shall not be entitled to any refund with respect to such
claim and the Company does not notify Executive in writing of its intent to
contest such determination within 30 days after the Company receives written
notice of such determination, then such advance shall be forgiven and shall not
be required to be repaid and the amount of such advance shall offset, to the
extent thereof, the amount of Gross-Up Payment required to be paid. Any contest
of a denial of refund shall be controlled by Section 5.4(d).

                                   ARTICLE VI.

                    EXPENSES, INTEREST AND DISPUTE RESOLUTION

     6.1 Legal Fees and Other Expenses.

          (a)  If Executive incurs legal fees or other expenses (including
     expert witness and accounting fees and arbitration costs and expenses under
     Section 6.3) in an effort to secure, preserve, establish entitlement to, or
     obtain benefits under this Supplement and Amendment, the Company shall,
     regardless of the outcome of such effort, reimburse Executive on a current
     basis (in accordance with Section 6.1(b)) for such fees and expenses.

                                      -31-
<PAGE>   37

          (b) Reimbursement of legal fees and expenses and gross-up payments
     shall be made monthly within 10 days after Executive's written submission
     of a request for reimbursement together with evidence that such fees and
     expenses were incurred.

          (c) If Executive does not prevail (after exhaustion of all available
     judicial remedies) in respect of a claim by Executive or by the Company
     hereunder, and the Company establishes before a court of competent
     jurisdiction that Executive had no reasonable basis for Executive's claim
     hereunder, or for Executive's response to the Company's claim hereunder, or
     that Executive acted in bad faith, no further reimbursement for legal fees
     and expenses shall be due to Executive in respect of such claim and
     Executive shall refund any amounts previously reimbursed hereunder with
     respect to such claim.

          (d)  In no event shall Executive be entitled to reimbursement under
     this Supplement and Amendment and under the Employment Agreement for the
     same fees, costs or expenses.

          (e)  The Company shall promptly reimburse Executive for all attorneys'
     fees, costs and expenses incurred by Executive in connection with the
     negotiation, execution and delivery of this Supplement and Amendment.

     6.2 Interest. If the Company does not pay any amount due to Executive under
this Supplement and Amendment within ten business days after such amount first
became due and owing, interest shall accrue on such amount from the date it
became due and owing until the date of payment at an annual rate equal to 300
basis points above the base commercial lending rate published in The Wall Street
Journal in effect from time to time during the period of such nonpayment.

     6.3 Binding Arbitration. Any dispute, controversy or claim arising out of
or in connection with or relating to this Supplement and Amendment or any breach
or alleged breach thereof, or any benefit or alleged benefit hereunder, shall be
submitted to and settled by binding arbitration in Des Moines, Iowa, in
accordance with the Commercial Arbitration Rules of the American Arbitration
Association. Any dispute, controversy or claim submitted for resolution shall be
submitted to three (3) arbitrators, each of whom is a nationally recognized
executive compensation specialist. The Company involved in the dispute,
controversy or claim, or Mutual if more than one Company is so involved, shall
select one arbitrator, the Executive shall select one arbitrator and the third
arbitrator shall be selected by the first two arbitrators. Any award rendered
shall be final and conclusive upon the parties and a judgment thereon may be
entered in the highest court of a forum, state or federal, having jurisdiction.
The expenses of the arbitration shall be borne according to Section 6.1. No
arbitration shall be commenced after the date when institution of legal or
equitable proceedings based upon such subject matter would be barred by the
applicable statute of limitations. Notwithstanding anything to the contrary
contained in this Section 6.3 or elsewhere in this Supplement and Amendment,
either party may bring an action in the District Court of Polk County, or the
United States District Court for the Southern District of Iowa, if jurisdiction
there lies, in order to maintain the status quo ante of the parties. The "status
quo ante" is defined as the last peaceable, uncontested status between the
parties. However, neither the party bringing the action nor the party defending
the action thereby waives its right to arbitration of any dispute, controversy
or claim arising out of or in connection or relating to this

                                      -32-
<PAGE>   38

     Supplement and Amendment. Notwithstanding anything to the contrary
     contained in this Section 6.3 or elsewhere in this Supplement and
     Amendment, either party may seek relief in the form of specific
     performance, injunctive or other equitable relief in order to enforce the
     decision of the arbitrator(s). The parties agree that in any arbitration
     commenced pursuant to this Supplement and Amendment, the parties shall be
     entitled to such discovery (including depositions, requests for the
     production of documents and interrogatories) as would be available in a
     federal district court pursuant to Rules 26 through 37 of the Federal Rules
     of Civil Procedure. In the event that either party fails to comply with its
     discovery obligations hereunder, the arbitrator(s) shall have full power
     and authority to compel disclosure or impose sanctions to the full extent
     of Rule 37 of the Federal Rules of Civil Procedure.

                                  Article VII.

                   No Set-off or Mitigation; No Double Payment

     7.1 No Set-off by Company. Executive's right to receive when due the
payments and other benefits provided for under this Supplement and Amendment is
absolute, unconditional and subject to no setoff, counterclaim or legal or
equitable defense. Time is of the essence in the performance by the Company of
its obligations under this Supplement and Amendment. Any claim which the Company
may have against Executive, whether for a breach of this Supplement and
Amendment or otherwise, shall be brought in a separate action or proceeding and
not as part of any action or proceeding brought by Executive to enforce any
rights against the Company under this Supplement and Amendment.

     7.2 No Mitigation. Executive shall not have any duty to mitigate the
amounts payable by the Company under this Supplement and Amendment by seeking
new employment or self-employment following termination. Except as specifically
otherwise provided in this Supplement and Agreement, all amounts payable
pursuant to this Supplement and Agreement shall be paid without reduction
regardless of any amounts of salary, compensation or other amounts which may be
paid or payable to Executive as the result of Executive's employment by another
employer or self-employment.

     7.3 No Double Payment. Notwithstanding any other provision of this
Supplement and Amendment, the Executive shall not be entitled to payment under
both this Supplement and Amendment and the Employment Agreement for the same
type of benefit or payment, to the extent such payment would reasonably be
considered duplicative. Amounts paid hereunder shall be reduced by amounts paid
under the Employment Agreement for the same type of benefit or payment, to the
extent such payment would reasonably be considered duplicative.

                                  ARTICLE VIII.

                            NON-EXCLUSIVITY OF RIGHTS

     8.1 Waiver of Certain Other Rights. To the extent that lump sum cash
severance payments are made to Executive pursuant to Article IV, Executive
hereby waives the right to receive severance payments or severance benefits
under any other Plan or agreement of the Company, including under the Employment
Agreement.

                                      -33-
<PAGE>   39

     8.2 Other Rights. Except as expressly provided in Section 8.1 or elsewhere
in this Supplement and Amendment, this Supplement and Amendment shall not
prevent or limit Executive's continuing or future participation in any benefit,
bonus, incentive or other Plans provided by the Company and for which Executive
may qualify, nor shall this Supplement and Amendment limit or otherwise affect
such rights as Executive may have under any other agreements with the Company.
The applicable provisions of the Employment Agreement (including the provisions
in Article VII (Restrictive Covenants)) shall continue to apply, except as
expressly provided in Sections 8.1 and 4.10 or elsewhere in this Supplement and
Amendment. Amounts which are vested benefits or which Executive is otherwise
entitled to receive under any Plan and any other payment or benefit required by
law at or after the Termination Date shall be payable in accordance with such
Plan or applicable law except as expressly modified by this Supplement and
Amendment.

     8.3 No Right to Continued Employment. Nothing in this Supplement and
Amendment shall guarantee the right of Executive to continue in employment, and
the Companies retain the right to terminate the Executive's employment at any
time for any reason or for no reason.

                                   ARTICLE IX.

                                  MISCELLANEOUS

     9.1 No Assignability. This Supplement and Amendment is personal to
Executive and without the prior written consent of the Company shall not be
assignable by Executive otherwise than by will or the laws of descent and
distribution. This Supplement and Amendment shall inure to the benefit of and be
enforceable by Executive's legal representatives.

     9.2 Successors. This Supplement and Amendment shall inure to the benefit of
and be binding upon the Company and its successors and assigns. The Company will
require any successor (whether direct or indirect, by purchase, merger,
consolidation or otherwise) to all or substantially all of the business or
assets of the Company to assume expressly and agree to perform this Supplement
and Amendment in the same manner and to the same extent that the Company would
be required to perform it if no such succession had taken place. Any successor
to the business or assets of the Company which assumes or agrees to perform this
Supplement and Amendment by operation of law, contract, or otherwise shall be
jointly and severally liable with the Company under this Supplement and
Amendment as if such successor were the Company.

     9.3 Payments to Beneficiary. If Executive dies before receiving amounts to
which Executive is entitled under this Supplement and Amendment, such amounts
shall be paid in a lump sum to Executive's Beneficiary (or estate).

     9.4 Non-Alienation of Benefits. Benefits payable under this Supplement and
Amendment shall not be subject in any manner to anticipation, alienation, sale,
transfer, assignment, pledge, encumbrance, charge, garnishment, execution or
levy of any kind, either voluntary or involuntary, before actually being
received by Executive, and any such attempt to dispose of any right to benefits
payable under this Supplement and Amendment shall be void.

     9.5 Severability. If any one or more Articles, Sections or other portions
of this Supplement and Amendment are declared by any court or governmental
authority to be unlawful or invalid, such unlawfulness or invalidity shall not
serve to invalidate any Article, Section or other portion not so declared to be
unlawful or invalid. Any Article, Section or other portion so declared to be
unlawful or invalid shall be construed so as to effectuate the terms of such
Article, Section or other portion to the fullest extent possible while remaining
lawful and valid.

modified except by written instrument executed by the Company and Executive.

                      PRINCIPAL MUTUAL HOLDING COMPANY AND

                        PRINCIPAL LIFE INSURANCE COMPANY

                     CHANGE-OF-CONTROL EMPLOYMENT AGREEMENT

     THIS AGREEMENT dated as of __________, 2000 (the "Agreement Date") is made
by and among Principal Mutual Holding Company, an Iowa mutual holding company
(together with all successors thereto, "Mutual"), Principal Financial Group,
Inc., an Iowa corporation, Principal Financial Services, Inc., an Iowa
corporation, and Principal Life Insurance Company, an Iowa corporation (together
with all successors thereto, "Life") (each of the foregoing referred to
individually as a "Company" or collectively as "Companies"), and ______________
("Executive").

                                    RECITALS

     The Companies have determined that it is in the best interests of the
Companies and their members, (and if, at the relevant time, any are stock
companies, their stockholders) to assure that the Companies will have the
continued service of Executive. The Companies also believe it is imperative to
reduce the distraction of Executive that would result from the personal
uncertainties caused by a pending or threatened change of control of Mutual, to
encourage Executive's full attention and dedication to the Companies, and to
provide Executive with compensation and benefits arrangements upon a change of
control which ensure that the expectations of Executive will be satisfied and
are competitive with those of similarly-situated businesses. This Agreement is
intended to accomplish these objectives.

                                   ARTICLE I.

                               CERTAIN DEFINITIONS

provided to Executive by the Company, but have not yet been paid or provided (as
applicable).

     1.5  "Affiliate" means any Person that directly or indirectly controls, is
controlled by, or is under common control with, a Company. For purposes of this
definition the term "control" with respect to any Person means the power to

or otherwise.

     1.6  "Agreement Date" -- see the introductory paragraph of this Agreement.

     1.7  "Agreement Term" means the period commencing on the Agreement Date and

Commencing on the first anniversary of the Agreement Date, the Agreement Term

term until, at any time after the first anniversary of the Agreement Date, the
Company delivers written notice (an "Expiration Notice") to Executive that the
Agreement shall expire on a date specified in the Expiration Notice (the
"Expiration Date") that is not less than 24 months after the date the Expiration
Notice is delivered to Executive; provided, however, that if an Effective Date
or an Imminent Control Change occurs before the Expiration Date specified in the
Expiration Notice, then such Expiration Notice shall be void and of no further
effect, provided, however, if such Imminent Control Change does not culminate in
a Consummation Date, then such Expiration Notice shall be reinstated and the
Agreement shall expire on the date originally specified as the Expiration Date,
or if later, the date the Imminent Control Change lapses. Notwithstanding
anything herein to the contrary, the Agreement Term shall end on the second
anniversary of the Effective Date.

     1.8  "Annual Bonus" -- see Section 2.2(b).

purpose the premature termination of any LTIP Performance Period that occurred
on or after the Effective Date), calculated as follows:

          (a) If the most recently granted LTIP Award was granted under the 1999
     Long-Term Performance Plan, the projected target award (stated as a
     percentage of Base Salary) as calculated at the beginning of the three-year
     award cycle which Executive would have been entitled to receive with
     respect to such most recent allocation of performance units as if "Gain
     from Operations" and "Return on Equity" (as such terms are defined in the
     1999 Long-Term Performance Plan) targets had been met.

          (b) If the most recently granted LTIP Award was granted under a New
     LTIP under which consecutive LTIP Performance Periods end each 12 months,
     the Executive's LTIP Target Award with respect to such most recent grant.

          (c) If the most recently granted LTIP Award was granted under a New
     LTIP under which consecutive LTIP Performance Periods end more or less
     frequently than

                                      -2-
<PAGE>   8

     each 12 months, the Executive's LTIP Target Award with respect to such most
     recent grant, multiplied by a fraction, the numerator of which is 12 and
     the denominator of which is the number of whole months between payments of
     LTIP Bonuses.

          (d) If the Executive has no LTIP Awards outstanding with respect to
     which the LTIP Performance Period has not yet ended, the amount shall be

     common stock of Mutual or of Voting Securities representing 25% or more of
     the combined voting power of all Voting Securities of Mutual (such an SEC
     Person, a "25% Owner"); or

          (b) the Mutual Incumbent Directors (determined using the Agreement
     Date as the baseline date) cease for any reason to constitute at least a
     majority of the Board; or

          (c) consummation of a merger, reorganization, consolidation, or
     similar transaction (any of the foregoing, a "Reorganization Transaction")
     where the Continuity of Ownership is not more than 60%; or

          (d) approval by the members of Mutual, if at the relevant time Mutual
     is a mutual life insurance holding company, or approval by the stockholders
     of Mutual, if at the relevant time Mutual is a stock company, of a plan or
     agreement for the sale or other disposition of all or substantially all of
     the consolidated assets of Mutual or a plan of liquidation of Mutual.

Notwithstanding the foregoing, a Change of Control shall not occur merely as a
result of (i) Demutualization, or (ii) an underwritten initial public offering
of common stock of Mutual as filed with the SEC, unless such initial public
offering results in any SEC Person becoming a 25% Owner. Notwithstanding the
occurrence of any of the foregoing events, a Change of Control

                                      -3-

     the Base Salary shall not be reduced and the term "Base Salary" shall
     thereafter refer to the increased amount; provided, however, that Base
     Salary may be reduced as part of

     of a Merger of Equals until the Merger of Equals Cessation Date, if any, at
     which time Section 2.2(c)(i) shall be applied by substituting the Merger of
     Equals Cessation Date for the Effective Date wherever such term appears.

                                      -17-
<PAGE>   23

           (a) During the Post-Change Employment Period or any Imminent Change
     Period, the Company may terminate Executive's employment at any time
     because of Executive's Disability by giving Executive or his legal
     representative, as applicable, (i) written notice in accordance with
     Section 10.8 of the Company's intention to terminate Executive's employment
     pursuant to this Section and (ii) a certification of Executive's Disability
     by a physician selected by the Company or its insurers, subject to the
     consent of Executive or Executive's legal representative, which consent
     shall not be unreasonably withheld or delayed. Executive's employment shall
     terminate effective on the 30th day after Executive's receipt of such
     notice (which such 30th day shall be deemed to be the date of the
     Disability) unless, before such 30th day, Executive shall have resumed the
     full-time performance of Executive's duties.

           (b) "Disability" means any medically determinable physical or mental
     impairment that has lasted for a continuous period of not less than six
     months and can be expected to be permanent or of indefinite duration, and
     that renders Executive unable to perform the duties required under this
     Agreement.

     3.2   Death. Executive's employment shall terminate automatically upon
Executive's death during the Post-Change Employment Period or Imminent Control
Change Period.

     3.3   Termination for Cause.

           (a) Change of Control that is not a Merger of Equals. During the
     Post-Change Employment Period that is not a Post-Merger of Equals Period,
     the Company may terminate Executive's employment for Cause solely in
     accordance with all of the substantive and procedural provisions of this
     Section 3.3(a).

               (i) Definition of Cause. For purposes of this section 3.3(a),
          "Cause" means any one or more of the following:

                    (1) Executive's commission of a felony or other crime
               involving fraud, dishonesty or moral turpitude;

                    (2) Executive's willful or reckless material misconduct in
               the performance of Executive's duties;

                    (3) Executive's habitual neglect of duties; or

                    (4) Executive's willful or intentional breach of this
               Agreement;

          provided, however, that for purposes of clauses (2), (3) and (4),
          Cause shall not include any one or more of the following:

                    (A) Executive's bad judgment

                    (B) Executive's negligence, other than Executive's habitual
               neglect of duties or gross negligence;

                                      -18-
<PAGE>   24

                    (C) any act or omission believed by Executive in good faith
               to have been in or not opposed to the interest of the Company
               (without intent of Executive to gain, directly or indirectly, a
               profit to which Executive was not legally entitled); or

                    (D) failure to meet performance goals, objectives or
               measures following good faith efforts to meet such goals,
               objectives or measures; and

          further provided that, if a breach of this Agreement involved an act,
          or a failure to act, which was done, or omitted to be done, by
          Executive in good faith and with a reasonable belief that Executive's
          act, or failure to act, was in the best interests of the Company or
          was required by applicable law or administrative regulation, such
          breach shall not constitute Cause if, within 30 days after Executive
          is given written notice of such breach that specifically refers to
          this Section, Executive cures such breach to the fullest extent that
          it is curable.

               (ii) Procedural Requirements for Termination for Cause. The
          Company shall strictly observe each of the following procedures:

                    (1) Board Meeting. A meeting of the Board shall be called
               for the stated purpose of determining whether Executive's acts or
               omissions constitute Cause and, if so, whether to terminate
               Executive's employment for Cause.

                    (2) Notice of Consideration. Not less than 30 days prior to
               the date of such meeting the Company shall provide Executive and
               each member of the Board written notice (a "Notice of
               Consideration") of (x) a detailed description of the acts or
               omissions alleged to constitute Cause, (y) the date, time and
               location of such meeting of the Board, and (z) Executive's rights
               under clause (3) below.

                     (3) Opportunity to Present Response. Executive shall have
               the opportunity to appear before the Board in person and, at
               Executive's option, with legal counsel, and/or to present to the
               Board a written response to the Notice of Consideration.

                     (4) Cause Determination. Executive's employment may be
               terminated for Cause only if (x) the acts or omissions specified
               in the Notice of Consideration did in fact occur and do
               constitute Cause as defined in this Section, (y) the Board makes
               a specific determination to such effect and to the effect that
               Executive's employment should be terminated for Cause ("Cause
               Determination") and (z) the Company thereafter provides Executive
               with a Notice of Termination which specifies in specific detail
               the basis of such Termination of Employment for Cause and which
               Notice shall be consistent with the reasons set forth in the
               Notice of Consideration. The Cause Determination shall require
               the affirmative vote of at least 66-2/3% of the members of the
               Board.

                                      -19-
<PAGE>   25

                     (iii) Standard of Review. In the event that the existence
               of Cause shall become an issue in any action or proceeding
               between the Company and Executive, the Company shall,
               notwithstanding the Cause determination referenced in clause
               (4)(y) of Section 3.3(a)(ii), have the burden of establishing
               that the actions or omissions specified in the Notice of
               Consideration did in fact occur and do constitute Cause and that
               the Company has satisfied the procedural requirements of Section
               3.3(a)(ii).

               (b) Merger of Equals. Section 3.3(a) shall not apply in the case
          of a Merger of Equals unless there occurs a Merger of Equals Cessation
          Date, at which time Section 3.3(a) shall apply to any termination for
          Cause during the Post-Change Employment Period for which the Notice of
          Consideration is given on or after the Merger of Equals Cessation
          Date. During any Post-Merger of Equals Period, the Company may
          terminate Executive's employment for Cause solely in accordance with
          all of the substantive and procedural provisions of this Section
          3.3(b).

                    (i) Definition of Cause. For purposes of this Section
               3.3(b), "Cause" shall have the same meaning as in Section
               3.3(a)(i).

                    (ii) Procedural Requirements for Termination for Cause. The
               Company shall strictly observe the procedures set forth in
               Section 3.3(a)(ii), except that

                         (1) If the Notice of Consideration is given to
                    Executive during a Post-Merger of Equals Period, Executive
                    shall have the opportunity to present to the board a written
                    response to the Notice of Consideration, but shall not have
                    the right to appear in person or by counsel before the
                    Board; and

                         (2) The Cause Determination shall require the
                    affirmative vote of a simple majority of the members of the
                    Board.

                    (iii) Standard of Review. If the Notice of Consideration is
               given to Executive during a Post-Merger of Equals Period, then in
               the event that the existence of Cause shall become an issue in
               any action or proceeding between the Company and Executive, the
               Board's Cause determination referenced in clause (4)(y) of
               Section 3.3(a)(ii) shall be binding on all parties.

               (c) Imminent Control Change Period. This Section 3.3 shall not
          apply during any Imminent Control Change Period that does not
          culminate in a Consummation Date. In the case of an Imminent Control
          Change Period that culminates in a Consummation Date, no termination
          of Executive's employment during the Imminent Control Change Period
          shall be deemed to have been for Cause unless all the substantive and
          procedural provisions of Section 3.3(c) shall have been satisfied:

                    (i) Definition of Cause. For purposes of this Section
               3.3(c), "Cause" shall have the meaning as in Section 3.3(a)(i),
               except that, for purposes of clauses

                                      -20-
<PAGE>   26

               (2), (3) and (4) of Section 3.3(a)(i), Cause shall not exclude
               failure to meet performance goals, objectives or measures.

               (ii) Procedural Requirements for Termination for Cause. To
          qualify as a termination for Cause, a termination by the Company
          during the Imminent Control Change Period shall have strictly complied
          with the procedures set forth in Section 3.3(b)(ii), substituting the
          phrase Imminent Control Change Period for Post-Merger of Equals Period
          wherever it appears.

               (iii) Standard of Review. If the Notice of Consideration is given
          to Executive during an Imminent Control Change Period, then in the
          event that the existence of Cause shall become an issue in any action
          or proceeding between the Company and Executive, the Board's Cause
          determination referenced in clause (4)(y) of Section 3.3(a)(ii) shall
          be binding on all parties.

     3.4  Good Reason.

          (a) Change of Control that is not a Merger of Equals. During the
     Post-Change Employment Period that is not a Merger of Equals, Executive may
     terminate his or her employment for Good Reason in accordance with the
     substantive and procedural provisions of this Section 3.4(a).

               (i) Good Reason Definition. For purposes of this Section 3.4(a),
          "Good Reason" means the occurrence of any one or more of the following
          actions or omissions during the Post-Change Employment Period other
          than during a Post-Merger of Equals Period:

                   (1) any failure to pay Executive's Base Salary in violation
               of Section 2.2(a) or any failure to increase Executive's Base
               Salary to the extent, if any, required by such Section;

                   (2) any failure to pay Executive's Annual Bonus or any
               reduction in Executive's bonus opportunity, in either case in
               violation of Section 2.2(b);

                   (3) any material adverse change in Executive's position
               (including offices, titles, or reporting requirements, but not
               reporting responsibilities), authority or duties as contemplated
               by Section 2.1(a)(i);

                   (4) any material reduction in aggregate compensation and
               benefits as provided in Article II;

                   (5) requiring Executive to be based at any office or
               location other than the location specified in Section 2.1(a);

                   (6) any other material breach of this Agreement by the
               Company;

                                      -21-
<PAGE>   27

                    (7) any Termination of Employment by the Company that
               purports to be for Cause, but is not in full compliance with all
               of the substantive and procedural requirements of this Agreement
               (any such purported termination shall be treated as a Termination
               of Employment without Cause for all purposes of this Agreement);
               or

                    (8) the failure at any time of a successor to the Company
               explicitly to assume and agree to be bound by this Agreement.

               (ii) Determination of Good Reason. Any reasonable determination
          by Executive that any of the events specified in subsection (i) above
          has occurred and constitutes Good Reason shall be conclusive and
          binding for all purposes, unless the Company establishes that
          Executive did not have any reasonable basis for such determination.

          (b) Merger of Equals. Section 3.4(a) shall not apply in the case of a
     Merger of Equals unless there occurs a Merger of Equals Cessation Date, at
     which time Section 3.4(a) shall apply to any termination for Good Reason
     during the Post-Change Employment Period for which the event(s)
     constituting Good Reason occurred on or after the Merger of Equals
     Cessation Date. During any Post-Merger of Equals Period, the Executive may
     terminate his or her employment for Good Reason in accordance with the
     substantive and procedural provisions of this Section 3.4(b).

               (i) Definition of Good Reason. For purposes of this Section
          3.4(b), "Good Reason" shall have the same meaning as in Section
          3.4(a)(i), except that (1) the act or omission shall have occurred
          during the Post-Merger of Equals Period, and (2) clauses 3.4(a)(i)(3)
          and (5) shall not apply.

               (ii) Determination of Good Reason. Executive's determination that
          an event constituting Good Reason has occurred during a Post-Merger of
          Equals Period shall not be entitled to any presumptive validity or
          other deference by a court.

          (c) Imminent Control Change Period. This Section 3.4 shall not apply
     during any Imminent Control Change Period that does not culminate in a
     Consummation Date. In the case of an Imminent Control Change Period that
     culminates in a Consummation Date, no termination of Executive's employment
     during the Imminent Control Change Period shall be deemed to have been for
     Good Reason unless all the substantive and procedural provisions of this
     Section 3.4(c) shall have been satisfied:

               (i) Definition of Good Reason. For purposes of this Section
          3.4(b), "Good Reason" shall have the same meaning as in Section
          3.4(a)(i), except that (1) the act or omission shall have occurred
          during the Imminent Control Change Period, and (2) clauses
          3.4(a)(i)(3) and (5) shall not apply.

               (ii) Determination of Good Reason. Executive's determination that
          an event constituting Good Reason has occurred during an Imminent
          Control Change

                                      -22-

          Period shall not be entitled to any presumptive validity or other
          deference by a court.

          (d) Notice by Executive. In the event of any Termination of Employment
     by Executive for Good Reason, Executive shall as soon as practicable
     thereafter notify the Company of the events constituting such Good Reason
     by a Notice of Termination. A delay in the delivery of such Notice of
     Termination or a failure by Executive to include in the Notice of
     Termination any fact or circumstance which contributes to a showing of Good
     Reason shall not waive any right of Executive under this Agreement or
     preclude Executive from asserting such fact or circumstance in enforcing
     rights under this Agreement; provided that no act or omission by the
     Company shall qualify as Good Reason (i) if Executive's Termination of
     Employment occurs more than 12 months after Executive first obtains actual
     knowledge of such act or omission or (ii) during a Post-Merger of Equals
     Period 12 months after the first date on which Executive obtained actual
     knowledge of the fact that no Merger of Equals has occurred or that a
     Merger of Equals Cessation has occurred.

                         (3) received the lump-sum severance benefits specified
                    in Section 4.1(a) (excluding LTIP Bonuses and any amounts

                    compensation in equal monthly installments during the period
                    of three years following the Termination Date,

          benefits actually payable to Executive under each defined-benefit Plan
          that is qualified under Section 401(a) of the Code and (y) the
          aggregate amounts previously paid (whether pursuant to Section 2.4 or

          accrued benefits under any unqualified or qualified defined
          contribution retirement plan maintained by the Company as of the
          Termination Date and forfeited by Executive by reason of the
          Termination of Employment.

          (b) Continuation of Welfare Benefits. Until the third anniversary of
     the Termination Date or such later date as any Plan may specify, the
     Company shall continue to provide to Executive and Executive's family
     welfare benefits (including medical, prescription, dental, disability,
     salary continuance, individual life, group life, accidental death and
     travel accident insurance plans and programs) which are at least as
     favorable as the most favorable Plans of the Company applicable to peer
     executives who are actively employed after the Termination Date and their
     families. The cost of such welfare benefits to Executive shall not exceed
     the cost of such benefits to actively employed peer executives of the
     Company as applicable from time to time. Executive's rights under this
     Section shall be in addition to, and not in lieu of, any post-termination
     continuation coverage or conversion rights Executive may have pursuant to
     applicable law, including continuation coverage required by Section 4980 of
     the Code. Notwithstanding anything herein to the contrary, such welfare

     harmless by the Companies to the greatest extent permitted under applicable
     Iowa law (or the law of the State of incorporation of any successor or
     Surviving Corporation) as the same now exists or may hereafter be amended
     (but, in the case of any such amendment, only to the extent that such
     amendment permits a Company to provide broader indemnification than was
     permitted prior to such amendment) and the Companies' respective by-laws as
     such exist on the Agreement Date if the Executive was, is, or is threatened
     to be, made a party to any pending, completed or threatened action, suit,
     arbitration, alternate dispute resolution mechanism, investigation,
     administrative hearing or any other proceeding whether civil, criminal,
     administrative or investigative, and whether formal or informal, by reason
     of the fact that the Executive is or was, or had agreed to become, a
     director, officer, employee, agent, or fiduciary of a Company or any other
     entity which the Executive is or was serving at the request of a Company
     ("Proceeding"), against all expenses (including all reasonable attorneys'
     fees) and all claims, damages, liabilities and losses incurred or suffered
     by the Executive or to which the Executive may become subject for any
     reason. A Proceeding shall not include any proceeding to the extent it
     concerns or relates to a matter described in Section 6.1(a) (concerning
     reimbursement of

                                      -25-
<PAGE>   31

     certain costs and expenses). Upon receipt from Executive of (i) a written
     request for an advancement of expenses, which Executive reasonably believes
     will be subject to indemnification hereunder and (ii) a written undertaking
     by Executive to repay any such amounts if it shall ultimately be determined
     that Executive is not entitled to indemnification under this Agreement or
     otherwise, Mutual shall advance such expenses to Executive or pay such
     expenses for Executive, all in advance of the final disposition of any such
     matter.

          (e) Directors' and Officers' Liability Insurance. For a period of six
     years after the Termination Date, the Companies shall provide Executive
     with coverage under a directors' and officers' liability insurance policy
     in amounts no less than, and on terms no less favorable than, those
     provided to senior executive officers and directors of the Companies on the
     Effective Date.

          (f) Stock Incentive Awards. Immediately prior to the Executive's
     Termination of Employment, Executive shall (i) become fully vested in, and
     may thereafter exercise in whole or in part, in accordance with the terms
     thereof, all outstanding Stock Options and (ii) become fully vested in all
     Restricted Shares.

     4.2 Termination During a Post-Merger of Equals Period. If, during a
Post-Merger of Equals Period, the Company terminates Executive's employment
other than for Cause or Disability, or if Executive terminates employment for
Good Reason, the Company's sole obligations to Executive under Articles II and
IV shall be as follows:

          (a) Severance Payments. The Company shall pay or provide Executive, in
     addition to all vested rights arising from Executive's employment as
     specified in Article II, a lump-sum cash amount, no more than thirty
     business days after the Termination Date, equal to the sum of all amounts
     described in Section 4.1(a).

          (b) Continuation of Welfare Benefits. Until the third anniversary of
     the Termination Date or such later date as any Plan may specify, the
     Company shall continue to provide to Executive and Executive's family
     welfare benefits with the same scope and cost as described in Section
     4.1(b). Executive's rights under this Section shall be in addition to, and
     not in lieu of, any post-termination continuation coverage or conversion
     rights Executive may have pursuant to applicable law, including
     continuation coverage required by Section 4980 of the Code. Notwithstanding
     anything herein to the contrary, such welfare benefits shall be secondary
     to any similar welfare benefits provided by the Executive's subsequent
     employer (if any).

          (c) Stock Incentive Awards. Immediately prior to the Executive's
     Termination of Employment, Executive shall (i) become fully vested in, and
     may thereafter exercise in whole or in part, in accordance with the terms
     thereof, all outstanding Stock Options and (ii) become fully vested in all
     Restricted Shares.

          (d) Outplacement. The Company shall pay on behalf of Executive
     reasonable fees and costs charged by the outplacement firm selected by the
     Company to provide outplacement services to Executive after the Termination
     Date, within ten business days of its receipt of an invoice therefor,
     subject to a maximum of $30,000.

                                      -26-
<PAGE>   32
          (e) Indemnification. The Executive shall be indemnified and held
     harmless by the Companies to the same extent as provided in Section 4.1(d).

          (f) Directors' and Officers' Liability Insurance. The Companies shall
     provide Executive with Directors' and Officers' Liability Insurance to the
     same extent as provided in Section 4.1(e).

     4.3  Termination During an Imminent Control Change Period (with no Change
of Control). If, during an Imminent Control Change Period, the Company
terminates Executive's employment other than for Disability and other than for a
reason that would constitute Cause if there were a Change of Control, or if
Executive terminates employment for a reason that would constitute Good Reason
if there were a Change of Control, and in either case the Imminent Control
Change Period does not culminate in a Consummation Date, the Company's sole
obligations to Executive under Articles II and IV shall be as follows:

          (a) Continuation of Welfare Benefits. Until the earlier of (i) the
     third anniversary of the Termination Date or (ii) the last day of the
     Imminent Control Change Period (or such later date as any Plan may
     specify), the Company shall continue to provide to Executive and
     Executive's family welfare benefits with the same scope and cost as
     described in Section 4.1(b). Executive's rights under this Section shall
     be considered a part of, and shall therefore reduce, any post-termination
     continuation coverage or conversion rights Executive may have pursuant to
     applicable law, including, continuation coverage required by Section 4980
     of the Code. Notwithstanding anything herein to the contrary, such welfare
     benefits shall be secondary to any similar welfare benefits provided by the
     Executive's subsequent employer (if any).

          (b) Outplacement. The Company shall pay on behalf of Executive
     reasonable fees and costs charged by the outplacement firm selected by the
     Company to provide outplacement services to Executive after the Termination
     Date, within ten business days of its receipt of an invoice therefor,
     subject to a maximum of $30,000. Notwithstanding the foregoing, all
     outplacement amounts payable pursuant to this Section 4.3(b) shall be
     reduced (but not below zero) by outplacement amounts paid to Executive on
     account of a Termination Date prior to the date payment is made under this
     Section 4.3(b).

          (c) Indemnification. The Executive shall be indemnified and held
     harmless by the Companies to the same extent as provided in Section 4.1(d),
     but only during the Imminent Control Change Period.

          (d) Directors' and Officers' Liability Insurance. The Companies shall
     provide the same level of directors' and officers' liability insurance for
     Executive as provided in Section 4.1(e), but only during the Imminent
     Control Change Period.

          (e) Vested Stock Options. Executive's vested Stock Options will:

              (i) not expire (unless such Stock Options would have expired had
          Executive remained an employee of the Company) during the Imminent
          Control Change Period; and

                                      -27-
<PAGE>   33
              (ii) continue to be exercisable after the Termination Date to the
          extent provided in the applicable grant agreement or Plan, and
          thereafter, such Stock Options shall not be exercisable during the
          Imminent Control Change Period.

     Upon the date the Imminent Control Change lapses without a Consummation
     Date Executive's vested Stock Options may be exercised, in whole or in
     part, during the 30-day period following the lapse of the Imminent Control
     Change, (but in no case shall Stock Options remain exercisable after the
     date on which such Stock Options would have expired if Executive had
     remained an employee of the Company).

          (f) Unvested Stock Options. Executive's unvested Stock Options will:

              (i) not expire (unless such Stock Options would have expired had
          Executive remained an employee of the Company) during the Imminent
          Control Change Period; and

              (ii) not continue to vest and not be exercisable during the
          Imminent Control Change Period.

     Upon the date the Imminent Control Change lapses without a Consummation
     Date, such unvested Stock Options will expire.

          (g) Restricted Shares. Executive's unvested Restricted Shares will:

              (i) not be forfeited during the Imminent Control Change Period;
          and

              (ii) not continue to vest during the Imminent Control Change
          Period.

     Upon the date the Imminent Control Change lapses without a Consummation
     Date, such unvested Restricted Stock shall be forfeited.

     4.4 Termination During an Imminent Control Change Period (which Culminates
in a Change of Control). If, during an Imminent Control Change Period that
culminates in a Consummation Date, the Company terminates Executive's employment
other than for Cause or Disability, or if Executive terminates employment for
Good Reason, the Company's sole obligations to Executive under Articles II and
IV shall be as follows:

          (a) Cash Severance Payments. The Company shall pay Executive, in
     addition to all vested rights arising from Executive's employment as
     specified in Article II, a lump-sum cash amount equal to the sum of all
     amounts described in Section 4.1(a). Such amount shall be paid no more than
     ten business days after an Effective Date that does not qualify as a Merger
     of Equals and no more than 30 business days after an Effective Date which
     does qualify as a Merger of Equals. Notwithstanding the foregoing, all
     amounts paid pursuant to this Section 4.4(a) shall be reduced (but not
     below zero) by amounts paid to Executive on account of the Termination of
     Employment, to the extent such amounts would reasonably be considered
     duplicative, prior to the date payment is made under this Section 4.4(a).

<PAGE>   34

          (b) Continuation of Welfare Benefits. Until the third anniversary of
     the Termination Date or such later date as any Plan may specify, the
     Company shall continue to provide to Executive and Executive's family
     welfare benefits with the same scope and cost as described in Section 4.1
     (b). Executive's rights under this Section shall be in addition to, and not
     in lieu of, any post-termination continuation coverage or conversion rights
     Executive may have pursuant to applicable law, including continuation
     coverage required by Section 4980 of the Code. Notwithstanding the
     foregoing, such welfare benefits shall be secondary to any similar welfare
     benefits provided by the Executive's subsequent employer (if any).

          (c) Outplacement. The Company shall pay on behalf of Executive
     reasonable fees and costs charged by the outplacement firm selected by the
     Company to provide outplacement services to Executive after the Termination
     Date, within ten business days of its receipt of an invoice therefor,
     subject to a maximum of $30,000. Notwithstanding the foregoing, all
     outplacement amounts payable pursuant to this Section 4.4(c) shall be
     reduced (but not below zero) by outplacement amounts paid to Executive on
     account of such Termination Date but prior to the date payment is made
     pursuant to this Section 4.4(c).

          (d) Indemnification. The Executive shall be indemnified and held
     harmless by the Companies to the same extent as provided in Section 4.1(d).

          (e) Directors' and Officers' Liability Insurance. The Companies shall
     provide Executive with Directors' and Officers' liability insurance to the
     same extent as provided in Section 4.1(e).

          (f) Unvested Stock Options. Executive's unvested Stock Options will:

              (i) not expire (unless such Stock Options would have so expired
          had Executive remained an employee of the Company) during the Imminent
          Control Change Period;

              (ii) not continue to vest during the Imminent Control Change
          Period; and

              (iii) not be exercisable during the Imminent Control Change
          Period;

     Immediately prior to the Consummation Date, such unvested Stock Options
     shall become fully vested, and may thereupon be exercised in whole or in
     part by the Executive at any time during the 30-day period following the
     Consummation Date (but in no case shall Stock Options remain exercisable
     after the date on which such Stock Options would have expired if Executive
     had remained an employee of the Company). Notwithstanding the foregoing, if
     the Consummation Date is a Reorganization Transaction and if so provided
     under the agreement pursuant to which the Reorganization Transaction is
     effected, then all Executive's Stock Options shall (a) be extinguished for
     such consideration as is provided for vested options under such agreement
     or (b) be converted into options to purchase the stock of the Surviving
     Corporation, and such converted options shall be subject to the same option
     terms and restrictions as those applicable on the Consummation Date.

                                      -29-
<PAGE>   35

          (g) Vested Stock Options. Executive's vested Stock Options will:

              (i) not expire (unless such Stock Options would have so expired
          had Executive remained an employee of the Company) during the Imminent
          Control Change Period; and

              (ii) continue to be exercisable after the Termination Date to the
          extent provided in the applicable grant agreement or Plan, and
          thereafter, such Stock Options shall not be exercisable during the
          Imminent Control Change Period.

     Upon the Consummation Date, such vested. Stock Options may be exercised by
     Executive in whole or in part, during the 30-day period following the
     Consummation Date, (but in no case shall Stock Options remain exercisable
     after the date on which such Stock Options would have expired if Executive
     had remained an employee of the Company). Notwithstanding any provision in
     this Section, if the Consummation Date is a Reorganization Transaction, and
     if so provided under the agreement pursuant to which such Reorganization
     Transaction is effected, then all of the Executive's vested Stock Options
     shall (a) be extinguished for such consideration as is provided for vested
     options under such agreement or (b) be converted into options to purchase
     the stock of the Surviving Corporation, and such converted options shall be
     subject to the same option terms as those applicable on the Consummation
     Date.

          (h) Restricted Shares. Executive's unvested Restricted Shares will:

              (i) not be forfeited during the Imminent Control Change Period;
          and

              (ii) not continue to vest during the Imminent Control Change
          Period.

     Immediately prior to the Consummation Date, Executive shall become fully
     vested in all of Executive's Restricted Stock and within ten business days
     after the Consummation Date, the Company shall deliver to Executive all of
     such shares theretofore held by or on behalf of the Company, which will be
     subject to the same terms which other stockholders of the Company receive
     in the transaction.

     4.5  Waiver and Release. Notwithstanding anything herein to the contrary,
the Company shall have no obligation to Executive under Section 4.1, 4.2, 4.3 or
4.4 or Article V unless and until Executive executes a release and waiver of
Mutual and the Companies, in substantially the same form as attached hereto as
Exhibit A.

     4.6  Termination by the Company for Cause. If the Company terminates
Executive's employment for Cause during the Post-Change Employment Period or
Imminent Control Change Period, the Company's sole obligation to Executive under
Articles II and IV shall be to pay Executive, pursuant to the Company's
then-effective Plans, a lump-sum cash amount equal to all Accrued Obligations
determined as of the Termination Date. The LTIP Bonus shall be governed
according to the terms of the LTIP and New LTIP, as applicable.

     4.7  Termination by Executive Other Than for Good Reason. If Executive
elects to retire or otherwise terminate employment during the Post-Change
Employment Period or Imminent Control Change Period other than for Good Reason,
Disability or death, the

                                      -30-
<PAGE>   36

Company's sole obligation to Executive under Articles II and IV shall be to pay
Executive, pursuant to the Company's then-effective Plans, a lump-sum cash
amount equal to all Accrued Obligations determined as of the Termination Date.
The LTIP Bonus shall be governed according to the terms of the LTIP and New
LTIP, as applicable.

     4.8  Termination by the Company for Disability. If the Company terminates
Executive's employment by reason of Executive's Disability during the
Post-Change Employment Period or Imminent Control Change Period, the Company's
sole obligation to Executive under Articles II and IV shall be as follows:

          (a) to pay Executive, pursuant to the Company's then-effective Plans,
     a lump-sum cash amount equal to all Accrued Obligations determined as of
     the Termination Date, and

          (b) to provide Executive disability and other benefits after the
     Termination Date that are not less than the most favorable of such benefits
     then available under Plans of the Company to disabled peer executives of
     the Company.

If the Termination Date occurred during an Imminent Control Change Period which
had a Consummation Date which is not also a Merger of Equals or a Post-Change
Employment Period other than a Post-Merger of Equals Period, such disability and
other benefits shall also be no less favorable, in the aggregate, than the most
favorable of the disability and other benefits available to Executive under such
Plans in effect at any time during the 90-day period immediately preceding (1)
the Effective Date if such Termination Date occurred during a Post-Change
Employment Period or (2) the date of the Imminent Control Change if such
Termination Date occurred during an Imminent Control Change Period. The LTIP
Bonus shall be governed according to the terms of the LTIP and New LTIP, as
applicable.

     4.9  If upon Death. If Executive's employment is terminated by reason of
Executive's death during the Post-Change Employment Period or Imminent Control
Change Period, the Company's sole obligations to Executive under Articles II and
IV shall be as follows:

          (a) to pay Executive's Beneficiary, pursuant to the Company's
     then-effective Plans, a lump-sum cash amount equal to all Accrued
     Obligations; and

          (b) to provide Executive's Beneficiary survivor and other benefits
     that are not less than the most favorable survivor and other benefits then
     available under Plans of the Company to the estates or the surviving
     families of peer executives of the Company.

If the Termination Date occurred during an Imminent Control Change which had a
Consummation Date which is not also a Merger of Equals or a Post-Change
Employment Period other than a Post-Merger of Equals Period, such survivor
benefits shall also be no less favorable, in the aggregate, than the most
favorable of the survivor benefits available to Executive under such Plans in
effect at any time during the 90-day period immediately preceding (1) the
Effective Date if such Termination Date occurred during a Post-Change Employment
Period or (2) the date of the Imminent Control Change if such Termination Date
occurred during an Imminent Control Change Period. The LTIP Bonus shall be
governed according to the terms of the LTIP and New LTIP, as applicable.

                                   ARTICLE V.

                   CERTAIN ADDITIONAL PAYMENTS BY THE COMPANY

     5.1  Gross-Up Payment. If at any time or from time to time, it shall be
determined by the Company's independent auditors, but only after an Effective
Date, that any payment or other benefit to Executive pursuant to Article II or
Article IV of this Agreement or otherwise ("Potential Parachute Payment") is or
will become subject to the excise tax imposed by Section 4999 of the Code or any
similar tax payable under any United States federal, state, local, foreign or
other law ("Excise Taxes"), then the Company shall pay or cause to be paid a tax
gross-up payment ("Gross-Up Payment") with respect to all such Excise Taxes and
other. Taxes on the Gross-Up Payment. The Gross-Up Payment shall be an amount
equal to the product of

          (a) The amount of the Excise Taxes (calculated at the effective
     marginal rates of all federal, state, local, foreign or other law),

     multiplied by

          (b) A fraction (the "Gross-Up Multiple"), the numerator or which is
     one (1.O), and the denominator of which is one (1.O) minus the lesser
     of (i) the sum, expressed as a decimal fraction, of the effective marginal
     rates of any Taxes and any Excise Taxes applicable to the Gross-Up Payment
     or (ii).80. If different rates of tax are applicable to various portions of
     a Gross-Up Payment, the weighted average of such rates shall be used. For
     purposes of this section, Executive shall be deemed to be subject to the
     highest effective marginal rate of Taxes.

The Gross-Up Payment is intended to compensate Executive for all such Excise
Taxes and any other Taxes payable by Executive with respect to the Gross-Up
Payment. The Company shall pay or cause to be paid the Gross-Up Payment to
Executive within ten (10) days of the calculation of such amount, but in no
event after the Executive makes the payment to the IRS of such Excise Taxes.

     5.2 Limitation on Gross-Up Payments.

         (a) To the extent possible, any payments or other benefits to
     Executive pursuant to Article II and Article IV of this Agreement shall be
     allocated as consideration for Executive's entry into the covenants of
     Article VIII.

         (b) Notwithstanding any other provision of this Article V, if the
     aggregate After-Tax Amount (as defined below) of the Potential Parachute
     Payments and Gross-Up Payment that, but for this Section 5.2, would be
     payable to Executive, does not exceed 110% of After-Tax Floor Amount (as
     defined below), then no Gross-Up Payment shall be made to Executive and the
     aggregate amount of Potential Parachute Payments payable to Executive shall
     be reduced (but not below the Floor Amount) to the largest amount which
     would both (i) not cause any Excise Tax to be payable by Executive and (ii)
     not cause any Potential Parachute Payments to become nondeductible by the
     Company by reason of Section 280G of the Code (or any successor provision).
     For purposes of the preceding sentence, Executive shall be deemed to be
     subject to the highest effective marginal rate of Taxes.

                                      -32-
<PAGE>   38

          (c) For purposes of this Agreement:

              (i) "After-Tax Amount" means the portion of a specified amount
          that would remain after payment of all Taxes paid or payable by
          Executive in respect of such specified amount;

              (ii) "Floor Amount" means the greatest pre-tax amount of Potential
          Parachute Payments that could be paid to Executive without causing
          Executive to become liable for any Excise Taxes in connection
          therewith; and

              (iii) "After-Tax Floor Amount" means the After-Tax Amount of the
          Floor Amount.

     5.3  Additional Gross-up Amounts. If, for any reason (whether pursuant to
subsequently enacted provisions of the Code, final regulations or published
rulings of the IRS, or a final judgment of a court of competent jurisdiction)
the Company's independent auditors later determine that the amount of Excise
Taxes payable by Executive is greater than the amount initially determined
pursuant to Section 5.1, then the Company shall, subject to Sections 5.2 and
5.4, pay Executive, within ten (10) days of such determination, or pay to the
IRS as required by applicable law, an amount (which shall also be deemed a
Gross-Up Payment) equal to the product of:

          (a) the sum of (i) such additional Excise Taxes and (ii) any interest,
     penalties, expenses or other costs incurred by Executive as a result of
     having taken a position in accordance with a determination made pursuant to
     Section 5.1 or 5.4,

     multiplied   by

          (b) the Gross-Up Multiple.

     5.4  Amount Increased or Contested.

          (a) Executive shall notify the Company in writing (an "Executive's
     Notice") of any claim by the IRS or other taxing authority (an "IRS Claim")
     that, if successful, would require the payment by Executive of Excise Taxes
     in respect of Potential Parachute Payments in an amount in excess of the
     amount of such Excise Taxes determined in accordance with Section 5.1.
     Executive's Notice shall include the nature and amount of such IRS Claim,
     the date on which such IRS Claim is due to be paid (the "IRS Claim
     Deadline"), and a copy of all notices and other documents or correspondence
     received by Executive in respect of such IRS Claim. Executive shall give
     the Executive's Notice as soon as practicable, but no later than the
     earlier of (i) 10 days after Executive first obtains actual knowledge of
     such IRS Claim or (ii) five days before the IRS Claim Deadline; provided,
     however, that any failure to give such Executive's Notice shall affect the
     Company's obligations under this Article only to the extent that the
     Company is actually prejudiced by such failure. If at least one business
     day before the IRS Claim Deadline the Company shall:

              (i) deliver to Executive a written certificate from the Company's
          independent auditors ("Company Certificate") to the effect that,
          notwithstanding

                                      -33-
<PAGE>   39

          the IRS Claim, the amount of Excise Taxes, interest or penalties
          payable by Executive is either zero or an amount less than the amount
          specified in the IRS Claim,

              (ii) pay to Executive, or to the IRS as required by applicable
          law, an amount (which shall also be deemed a Gross-Up Payment) equal
          to difference between the product of (x) amount of Excise Taxes,
          interest and penalties specified in the Company Certificate, if any,
          multiplied by (y) the Gross-Up Multiple, less the portion of such
          product, if any, previously paid to Executive by the Company, and

              (iii) direct Executive pursuant to Section 5.4(d) to contest the
          balance of the IRS Claim,

     then Executive shall pay only the amount, if any, of Excise Taxes, interest
     and penalties specified in the Company Certificate. In no event shall
     Executive pay an IRS Claim earlier than 30 business days after having given
     an Executive's Notice to the Company (or, if sooner, the IRS Claim
     Deadline).

          (b) At any time after the payment by Executive of any amount of Excise
     Taxes, other Taxes or related interest or penalties in respect of Potential
     Parachute Payments (including any such amount equal to or less than the
     amount of such Excise Taxes specified in any Company Certificate, or IRS
     Claim), the Company may in its discretion require Executive to pursue a
     claim for a refund (a "Refund Claim") of all or any portion of such Excise
     Taxes, other Taxes, interest or penalties as may be specified by the
     Company in a written notice to Executive.

          (c) If the Company notifies Executive in writing that the Company
     desires Executive to contest an IRS Claim or to pursue a Refund Claim,
     Executive shall:

              (i) give the Company all information that it reasonably requests
          in writing from time to time relating to such IRS Claim or Refund
          Claim, as applicable,

              (ii) take such action in connection with such IRS Claim or Refund
          Claim (as applicable) as the Company reasonably requests in writing
          from time to time, including accepting legal representation with
          respect thereto by an attorney selected by the Company, subject to the
          approval of Executive (which approval shall not be unreasonably
          withheld or delayed),

              (iii) cooperate with the Company in good faith to contest such IRS
          Claim or pursue such Refund Claim, as applicable,

              (iv) permit the Company to participate in any proceedings relating
          to such IRS Claim or Refund Claim, as applicable, and

              (v) contest such IRS Claim or prosecute Refund Claim (as
          applicable) to a determination before any administrative tribunal, in
          a court of initial

                                      -34-
<PAGE>   40

          jurisdiction and in one or more appellate courts, as the Company may
          from time to time determine in its discretion.

     The Company shall control all proceedings in connection with such IRS Claim
     or Refund Claim (as applicable) and in its discretion may cause Executive
     to pursue or forego any and all administrative appeals, proceedings,
     hearings and conferences with the Internal Revenue Service or other taxing
     authority in respect of such IRS Claim or Refund Claim (as applicable);
     provided that (i) any extension of the statute of limitations relating to
     payment of taxes for the taxable year of Executive relating to the IRS
     Claim is limited solely to such IRS Claim, (ii) the Company's control of
     the IRS Claim or Refund Claim (as applicable) shall be limited to issues
     with respect to which a Gross-Up Payment would be payable, and (iii)
     Executive shall be entitled to settle or contest, as the case may be, any
     other issue raised by the Internal Revenue Service or other taxing
     authority.

          (d) The Company may at any time in its discretion direct Executive to
     (i) contest the IRS Claim in any lawful manner or (ii) pay the amount
     specified in an IRS Claim and pursue a Refund Claim; provided, however,
     that if the Company directs Executive to pay an IRS Claim and pursue a
     Refund Claim, the Company shall advance the amount of such payment to
     Executive on an interest-free basis and shall indemnify Executive, on an
     after-tax basis, for any Excise Tax or income tax, including related
     interest or penalties, imposed with respect to such advance.

          (e) The Company shall pay directly all legal, accounting and other
     costs and expenses (including additional interest and penalties) incurred
     by the Company or Executive in connection with any IRS Claim or Refund
     Claim, as applicable, and shall indemnify Executive, on an after-tax basis,
     for any Excise Tax or income tax, including related interest and penalties,
     imposed as a result of such payment of costs and expenses.

     5.5  Refunds. If, after the receipt by Executive or the IRS of any payment
or advance of Excise Taxes or other Taxes by the Company pursuant to this
Article, Executive receives any refund with respect to such Excise Taxes,
Executive shall (subject to the Company's complying with any applicable
requirements of Section 5.4) promptly pay the Company the amount of such refund
(together with any interest paid or credited thereon after taxes applicable
thereto). If, after the receipt by Executive of an amount advanced by the
Company pursuant to Section 5.4 or receipt by the IRS of an amount paid by the
Company on behalf of the Executive pursuant to Section 5.4, a determination is
made that Executive shall not be entitled to any refund with respect to such
claim and the Company does not notify Executive in writing of its intent to
contest such determination within 30 days after the Company receives written
notice of such determination, then such advance shall be forgiven and shall not
be required to be repaid and the amount of such advance shall offset, to the
extent thereof, the amount of Gross-Up Payment required to be paid. Any contest
of a denial of refund shall be controlled by Section 5.4(d).

                                   ARTICLE VI.

                    EXPENSES, INTEREST AND DISPUTE RESOLUTION

     6.1  Legal Fees and Other Expenses.

                                      -35-
<PAGE>   41
          (a) If, after the Agreement Date, Executive incurs legal fees or other
     expenses (including expert witness and accounting fees and arbitration
     costs and expenses under Section 6.3) in an effort to secure, preserve, or
     obtain benefits under this Agreement, the Company shall, regardless of the
     outcome of such effort, reimburse Executive on a current basis (in
     accordance with Section 6.1(b)) for such fees and expenses.

          (b) Reimbursement of legal fees and expenses and gross-up payments
     shall be made monthly within 10 days after Executive's written submission
     of a request for reimbursement together with evidence that such fees and
     expenses were incurred.

          (c) If Executive does not prevail (after exhaustion of all available
     judicial remedies) in respect of a claim by Executive or by the Company
     hereunder, and the Company establishes before a court of competent
     jurisdiction that Executive had no reasonable basis for Executive's claim
     hereunder, or for Executive's response to the Company's claim hereunder, or
     that Executive acted in bad faith, no further reimbursement for legal fees
     and expenses shall be due to Executive in respect of such claim and
     Executive shall refund any amounts previously reimbursed hereunder with
     respect to such claim.

     6.2  Interest. If the Company does not pay any amount due to Executive
under this Agreement within ten business days after such amount first became due
and owing, interest shall accrue on such amount from the date it became due and
owing until the date of payment at an annual rate equal to 300 basis points
above the base commercial lending rate published in The Wall Street Journal in
effect from time to time during the period of such nonpayment.

     6.3  Binding Arbitration. Any dispute, controversy or claim arising out of
or in connection with or relating to this Agreement or any breach or alleged
breach thereof, or any benefit or alleged benefit hereunder, shall be submitted
to and settled by binding arbitration in Des Moines, Iowa, in accordance with
the Commercial Arbitration Rules of the American Arbitration Association. Any
dispute, controversy or claim submitted for resolution shall be submitted to
three (3) arbitrators, each of whom is a nationally recognized executive
compensation specialist. The Company involved in the dispute, controversy or
claim, or Mutual if more than one Company is so involved, shall select one
arbitrator, the Executive shall select one arbitrator and the third arbitrator
shall be selected by the first two arbitrators. Any award rendered shall be
final and conclusive upon the parties and a judgment thereon may be entered in
the highest court of a forum, state or federal, having jurisdiction. The
expenses of the arbitration shall be borne according to Section 6.1. No
arbitration shall be commenced after the date when institution of legal or
equitable proceedings based upon such subject matter would be barred by the
applicable statute of limitations. Notwithstanding anything to the contrary
contained in this Section 6.3 or elsewhere in this Agreement, either party may
bring an action in the District Court of Polk County, or the United States
District Court for the Southern District of Iowa, if jurisdiction there lies, in
order to maintain the status quo ante of the parties. The "status quo ante" is
defined as the last peaceable, uncontested status between the parties. However,
neither the party bringing the action nor the party defending the action thereby
waives its right to arbitration of any dispute, controversy or claim arising out
of or in connection or relating to this Agreement. Notwithstanding anything to
the contrary contained in this Section 6.3 or elsewhere in this Agreement,
either party may seek relief in the form of specific performance, injunctive or
other equitable relief in order to enforce the decision of the arbitrator(s).
The parties agree that

                                      -36-
<PAGE>   42

in any arbitration commenced pursuant to this Agreement, the parties shall be
entitled to such discovery (including depositions, requests for the production
of documents and interrogatories) as would be available in a federal district
court pursuant to Rules 26 through 37 of the Federal Rules of Civil Procedure.
In the event that either party fails to comply with its discovery obligations
hereunder, the arbitrator(s) shall have full power and authority to compel
disclosure or impose sanctions to the full extent of Rule 37 of the Federal
Rules of Civil Procedure.

                                  ARTICLE VII.

                            NO SET-OFF OR MITIGATION

     7.1  No Set-off by Company. Executive's right to receive when due the
payments and other benefits provided for under this Agreement is absolute,
unconditional and subject to no setoff, counterclaim or legal or equitable
defense. Time is of the essence in the performance by the Company of its
obligations under this Agreement. Any claim which the Company may have against
Executive, whether for a breach of this Agreement or otherwise, shall be brought
in a separate action or proceeding and not as part of any action or proceeding
brought by Executive to enforce any rights against the Company under this
Agreement.

     7.2  No Mitigation. Executive shall not have any duty to mitigate the
amounts payable by the Company under this Agreement by seeking new employment or
self-employment following termination. Except as specifically otherwise
provided in this Agreement, all amounts payable pursuant to this Agreement shall
be paid without reduction regardless of any amounts of salary, compensation or
other amounts which may be paid or payable to Executive as the result of
Executive's employment by another employer or self-employment.

                                  ARTICLE VIII.

                       CONFIDENTIALITY AND NONCOMPETITION

     8.1  Confidential Information. The Executive acknowledges that in the
course of performing services for the Companies and Affiliates, he may create,
develop, learn of, receive or contribute non-public information, ideas,
processes, methods, designs, devices, inventions, data, models and other
information relating to the Companies and their Affiliates or their products,
services, businesses, operations, employees or customers, whether in tangible or
intangible form, and that the Companies or their Affiliates desire to protect
and keep secret and confidential, including trade secrets and information from
third parties that the Companies or their Affiliates are obligated to keep
confidential ("Confidential Information"). Confidential Information shall not
include: (i) information that is or becomes generally known through no fault of
Executive; (ii) information received from a third party outside of the Company
that was disclosed without a breach of any confidentiality obligation; or (iii)
information approved for release by written authorization of the Company. The
Executive recognizes that all such Confidential Information is the sole and
exclusive property of the Companies and their Affiliates, and that disclosure of
Confidential Information would cause damage to the Companies and their
Affiliates. The Executive agrees that, except as required by the duties of his
employment with any of the Companies or any of their and/or its Affiliates and
except in connection with enforcing the Executive's rights under this Agreement
or if compelled by a court or governmental agency, in each case provided that
prior written notice is given to Mutual, he will

                                      -37-
<PAGE>   43

not, without the consent of Mutual, willfully disseminate or otherwise disclose,
directly or indirectly, any Confidential Information obtained during his
employment with any of the Companies or their Affiliates, and will take all
necessary precautions to prevent disclosure, to any unauthorized individual or
entity inside or outside the Company, and will not use the Confidential
Information or permit its use for the benefit of Executive or any other person
or entity other than the Companies or the Affiliates These obligations shall
continue during and after the termination of Executive's employment (whether or
not after a Change of Control or an Imminent Control Change).

     8.2  Non-Competition. During the period beginning on the Agreement Date and
ending on the first to occur of (x) the first anniversary of a Termination Date
occurring during a Post-Change Employment Period or Imminent Control Change
Period and caused by (I) a termination of Executive's employment by the
Company other than for Disability or Cause or (II) a Termination of Employment
by Executive for Good Reason, and, in either event of (I) or (II) of this
Section 8.2, Executive receives benefits under Article IV, or (y) a Termination
Date other than that described in clause (x) of this Section 8.2, Executive
shall not at any time, directly or indirectly, in any capacity:

          (a) engage or participate in, become employed by, serve as a director
     of, or render advisory or consulting or other services in connection with,
     any Competitive Business; provided, however, that after the Termination
     Date this Section 8.2 shall not preclude Executive from being an employee
     of, or consultant to, any business unit of a Competitive Business if (i)
     such business unit does not qualify as a Competitive Business in its own
     right and (ii) Executive does not have any direct or indirect involvement
     in, or responsibility for, any operations of such Competitive Business that
     cause it to qualify as a Competitive Business.

          (b) make or retain any financial investment, whether in the form of
     equity or debt, or own any interest, in any Competitive Business. Nothing
     in this subsection shall, however, restrict Executive from making an
     investment in any Competitive Business if such investment does not (i)
     represent more than 1% of the aggregate market value of the outstanding
     capital stock or debt (as applicable) of such Competitive Business, (ii)
     give Executive any right or ability, directly or indirectly, to control or
     influence the policy decisions or management of such Competitive Business,
     and (iii) create a conflict of interest between Executive's duties under
     this Agreement and his interest in such investment.

     8.3  Non-Solicitation. During the period beginning on the Agreement Date
and ending on the first anniversary of any Termination Date, whether or not
after a Change of Control or Imminent Control Change, Executive shall not,
directly or indirectly:

          (a) other than in connection with the good-faith performance of his
     duties as an officer of the Company, encourage any employee or agent of the
     Company to terminate his or her relationship with the Company;

          (b) employ, engage as a consultant or adviser, or solicit the
     employment or engagement as a consultant or adviser, of any employee or
     agent of the Company (other

                                      -38-
<PAGE>   44

     than by the Company or its Affiliates), or cause or encourage any Person to
     do any of the foregoing;

          (c) establish (or take preliminary steps to establish) a business
     with, or encourage others to establish (or take preliminary steps to
     establish) a business with, any employee or agent of the Company; or

          (d) interfere with the relationship of the Company with, or endeavor
     to entice away from the Company, any Person who or which at any time during
     the period commencing one year prior to the Agreement Date was or is a
     material customer or material supplier of, or maintained a material
     business relationship with, the Company.

     8.4  Intellectual Property. During the employment period, whether or not
after a Change of Control or Imminent Control Change, Executive shall disclose
immediately to the Company all ideas, inventions and business plans that he
makes, conceives, discovers or develops alone or with others during the course
of his employment with the Company, including any inventions, modifications,
discoveries, developments, improvements, computer programs, processes, products
or procedures (whether or not protectable upon application by copyright, patent,
trademark, trade secret or other proprietary rights) ("Work Product") that: (i)
relate to the business of the Company or any customer or supplier to the Company
or any of the products or services being developed, manufactured, sold or
otherwise provided by the Company or that may be used in relation therewith; or
(ii) result from tasks assigned to Executive by the Company; or (iii) result
from the use of the premises or personal property (whether tangible or
intangible) owned, leased or contracted for by the Company. Executive agrees
that any Work Product shall be the property of the Company and, if subject to
copyright, shall be considered a "work made for hire" within the meaning of the
Copyright Act of 1976, as amended (the "Act"). If and to the extent that any
such Work Product is found as a matter of law not to be a "work made for hire"
within the meaning of the Act, Executive expressly assigns to the Company all
right, title and interest in and to the Work Product, and all copies thereof,
and the copyright, patent, trademark, trade secret and all their proprietary
rights in the Work Product, without further consideration, free from any claim,
lien for balance due or rights of retention thereto on the part of Executive.

          (a) The Company hereby notifies Executive that the preceding paragraph
     does not apply to any inventions for which no equipment, supplies,
     facility, or trade secret information of the Company was used and which was
     developed entirely on the Executive's own time, unless: (i) the invention
     relates (a) to the Company's business, or (b) to the Company's actual or
     demonstrably anticipated research or development, or (ii) the invention
     results from any work performed by the Executive for the Company.

          (b) Executive agrees that upon disclosure of Work Product to the
     Company, Executive will, during his employment and at any time thereafter,
     at the request and cost of the Company, execute all such documents and
     perform all such acts as the Company or its duly authorized agents may
     reasonably require: (i) to apply for, obtain and vest in the name of the
     Company alone (unless the Company otherwise directs) letters patent,
     copyrights or other analogous protection in any country throughout the
     world, and when so obtained or vested to renew and restore the same; and
     (ii) to defend any opposition

                                      -39-
<PAGE>   45

     proceedings in respect of such applications and any opposition proceedings
     or petitions or applications for revocation of such letters patent,
     copyright or other analogous protection.

          (c) In the event that the Company is unable, after reasonable effort,
     to secure Executive's signature on any letters patent, copyright or other
     analogous protection relating to Work Product, whether because of
     Executive's physical or mental incapacity or for any other reason
     whatsoever, Executive hereby irrevocably designates and appoints the
     Company and its duly authorized officers and agents as his agent and
     attorney-in-fact, to act for and on his behalf to execute and file any such
     application or applications and to do all other lawfully permitted acts to
     further the prosecution and issuance of letters patent, copyright and other
     analogous protection with the same legal force and effect as if personally
     executed by Executive.

     8.5 Reasonableness of Restrictive Covenants.

          (a) Executive acknowledges that the covenants contained in Sections
     8.1, 8.2, 8.3 and 8.4 are reasonable in the scope of the activities
     restricted, the geographic area covered by the restrictions, and the
     duration of the restrictions, and that such covenants are reasonably
     necessary to protect the Company's legitimate interests in its Confidential
     Information and in its relationships with its employees, customers and
     suppliers. Executive further acknowledges such covenants are essential
     elements of this Agreement and that, but for such covenants, the Company
     would not have entered into this Agreement.

          (b) The Company and Executive have each consulted with their
     respective legal counsel and have been advised concerning the
     reasonableness and propriety of such covenants. Executive acknowledges that
     his observance of the covenants contained in Sections 8.1, 8.2, 8.3 and 8.4
     will not deprive him of the ability to earn a livelihood or to support his
     dependents.

     8.6 Right to Injunction; Survival of Undertakings.

          (a) In recognition of the confidential nature of the Confidential
     Information, and in recognition of the necessity of the limited
     restrictions imposed by Sections 8.1, 8.2, 8.3 and 8.4 the parties
     agree that it would be impossible to measure solely in money the damages
     which the Company would suffer if Executive were to breach any of his
     obligations under such Sections. Executive acknowledges that any breach of
     any provision of such Sections would irreparably injure the Company.
     Accordingly, Executive agrees that if he breaches any of the provisions of
     such Sections, the Company shall be entitled, in addition to any other
     remedies to which the Company may be entitled under this Agreement or
     otherwise, to an injunction to be issued by a court of competent
     jurisdiction, to restrain any breach, or threatened breach, of such
     provisions, and Executive hereby waives any right to assert any claim or
     defense that the Company has an adequate remedy at law for any such breach.

          (b) If a court determines that any of the covenants included in this
     Article VIII is unenforceable in whole or in part because of such
     covenant's duration or geographical or other scope, such court shall have
     the power to modify the duration or scope of such

                                      -40-
<PAGE>   46

     provision, as the case may be, so as to cause such covenant as so modified
     to be enforceable.

          (c) All of the provisions of this Article VIII shall survive any
     Termination of Employment without regard to (i) the reasons for such
     termination or (ii) the expiration of the Agreement Term.

          (d) No Company shall have any further obligation to pay or provide
     severance or benefits under Article IV if a court determines that the
     Executive has breached any covenant in this Article VIII.

                                   ARTICLE IX.

                            NON-EXCLUSIVITY OF RIGHTS

     9.1  Waiver of Certain Other Rights. To the extent that lump sum cash
severance payments are made to Executive pursuant to Article IV, Executive
hereby waives the right to receive severance payments or severance benefits
under any other Plan or agreement of the Company.

     9.2 Other Rights. Except as expressly provided in Section 9.1 or elsewhere
in this agreement, this Agreement shall not prevent or limit Executive's
continuing or future participation in any benefit, bonus, incentive or other
Plans provided by the Company and for which Executive may qualify, nor shall
this Agreement limit or otherwise affect such rights as Executive may have under
any other agreements with the Company. Amounts which are vested benefits or
which Executive is otherwise entitled to receive under any Plan and any other
payment or benefit required by law at or after the Termination Date shall be
payable in accordance with such Plan or applicable law except as expressly
modified by this Agreement.

     9.3  No Right to Continued Employment. Nothing in this Agreement shall
guarantee the right of Executive to continue in employment, and the Companies
retain the right to terminate the Executive's employment at any time for any
reason or for no reason.

                                   ARTICLE X.

                                  MISCELLANEOUS

     10.1 No Assignability. This Agreement is personal to Executive and without
the prior written consent of the Company shall not be assignable by Executive
otherwise than by will or the laws of descent and distribution. This Agreement
shall inure to the benefit of and be enforceable by Executive's legal
representatives.

     10.2 Successors. This Agreement shall inure to the benefit of and be
binding upon the Company and its successors and assigns. The Company will
require any successor (whether direct or indirect, by purchase, merger,
consolidation or otherwise) to all or substantially all of the business or
assets of the Company to assume expressly and agree to perform this Agreement in
the same manner and to the same extent that the Company would be required to
perform it if no such succession had taken place. Any successor to the business
or assets of the Company

                                      -41-
<PAGE>   47

which assumes or agrees to perform this Agreement by operation of law, contract,
or otherwise shall be jointly and severally liable with the Company under this
Agreement as if such successor were the Company.

     10.3 Payments to Beneficiary. If Executive dies before receiving amounts to
which Executive is entitled under this Agreement, such amounts shall be paid in
a lump sum to one or more beneficiaries designated in writing by Executive
(each, a "Beneficiary"). If none is so designated, the Executive's estate shall
be his or her Beneficiary.

     10.4 Non-Alienation of Benefits. Benefits payable under this Agreement
shall not be subject in any manner to anticipation, alienation, sale, transfer,
assignment, pledge, encumbrance, charge, garnishment, execution or levy of any
kind, either voluntary or involuntary, before actually being received by
Executive, and any such attempt to dispose of any right to benefits payable
under this Agreement shall be void.

     10.5 Severability. If any one or more Articles, Sections or other portions
of this Agreement are declared by any court or governmental authority to be
unlawful or invalid, such unlawfulness or invalidity shall not serve to
invalidate any Article, Section or other portion not so declared to be unlawful
or invalid. Any Article, Section or other portion so declared to be unlawful or
invalid shall be construed so as to effectuate the terms of such Article,
Section or other portion to the fullest extent possible while remaining lawful
and valid.

     10.6 Amendments. This Agreement shall not be amended or modified except by
written instrument executed by the Company and Executive.

     10.7 Notices. All notices and other communications under this Agreement
shall be in writing and delivered by hand, by nationally-recognized delivery
service that promises overnight delivery, or by first-class registered or

     10.13  Waiver. Executive's failure to insist upon strict compliance with
any provision of this Agreement shall not be deemed a waiver of such provision
or any other provision of this Agreement. A waiver of any provision of this
Agreement shall not be deemed a waiver of any other provision, and any waiver of
any default in any such provision shall not be deemed a waiver of any later
default thereof or of any other provision.

     10.14  Joint and Several Liability. The obligations of the Companies to
Executive under this Agreement shall be joint and several.
