                         EXECUTIVE SEVERANCE AGREEMENT

     THIS EXECUTIVE SEVERANCE AGREEMENT (the "Agreement") is entered into as of
the 1st day of January, 1999, by and between RightCHOICE Managed Care, Inc., a

     WHEREAS, RightCHOICE has engaged the services of Executive as an "at-will"
employee of RightCHOICE; and

     WHEREAS, RightCHOICE and Executive have entered into an Officer Severance
Agreement dated as of Jan. 1, 1999 (the "Officer Agreement") under which, as a
condition of Executive's employment, Executive has agreed to be bound by certain
covenants set forth in the Officer Agreement and RightCHOICE has agreed to
provide Executive certain severance benefits upon the terms and conditions set
forth in the Officer Agreement;

     WHEREAS, the Compensation Committee of RightCHOICE's Board of Directors
believes that the concerns applicable to senior executives when certain
corporate events occur are such that, in order to facilitate senior executives'
focusing on management issues in a manner that best serves the interests of all
stakeholders, such executives of RightCHOICE should have the protections set
forth herein in the event that a Change in Control, as defined herein, occurs;

     NOW, THEREFORE, in consideration of the mutual promises herein contained,
and intending to be legally bound, the parties hereto do hereby agree as
follows:

                                   SECTION 1
                                   ---------

or nonqualified deferred compensation arrangement or contributed to a welfare
benefit plan pursuant to an election under a cafeteria plan) to Executive by the
Company during a calendar year which is in the most recent five-consecutive-
calendar-year period (or such shorter period of consecutive calendar years
during which Executive has been employed by the Company) ending on or before the
date of a Change in Control:

               (i)  base salary; and

               (ii) payments under any of the following incentive programs:

                         .    Supplemental Income Plan;

                         .    Short Term Public Offering Bonus;

                              RightCHOICE Managed Care, Inc. Board of Directors
                              specifically approves payments under such

For purposes of clarity and without limiting the generality of the foregoing

          -----

     E.   Change in Control. "Change in Control" shall mean the occurrence,
          -----------------
while Executive is employed by Company and this Agreement is in effect, of any
one or more of the following events:

               (i)   the merger, consolidation or other reorganization of
     Company in which any class of the outstanding common stock of Company is
     converted into or exchanged for a different class of securities of the
     Company, a class of securities of any other issuer, except an Affiliate,
     cash or other property (provided, however, that, regardless of anything to
     the contrary in this Agreement, the conversion or exchange of the
     outstanding Class B common stock of RightCHOICE Managed Care, Inc. into or
     for Class A common stock of RightCHOICE Managed Care, Inc. shall not be
     deemed to be a Change in Control);

               (ii)  the sale, lease or exchange of all or substantially all of
     the assets of Company or Parent to any other corporation or entity (except
     an Affiliate);

               (iii) the final adoption, in a manner making such plan legally
     effective without any higher level of approval or action, of a plan of
     complete liquidation and dissolution of the Company or Parent;

               (iv)  the acquisition (other than acquisition pursuant to any
     other clause of this definition) by any person or entity (including without
     limitation a partnership, limited partnership, syndicate or other group),
     of more than fifty (50) percent (based on total voting power) of any class
     of Company's or Parent's outstanding stock (or other equity ownership
     interests); provided, however, that nothing in this Section 2(E)(iv) shall
     be construed as deeming a Change in Control to have occurred if any such
     person or entity that is considered to own more than fifty (50) percent
     (based on total voting power) of such class of Company's or Parent's
     outstanding stock (or other equity ownership interests) prior to such
     acquisition, acquires additional shares of such class of stock (or other
     equity ownership). Where an entity does not have outstanding stock (such as
     the Parent), the above will be deemed to have occurred if a transaction
     occurs in which the entity becomes subject to the direction or oversight by
     a person that is not an Affiliate, and such direction or oversight includes
     the ability of the person to set policy for the entity, and/or govern the
     operations of the Parent, and/or control the entity's assets or the stock
     the entity owns in RightCHOICE Managed Care, Inc.

                                       3
<PAGE>

               (v)   as a result of, or in connection with, a contested election
     of directors of the Company, the persons who were directors of Company
     before such election cease to constitute a majority of the directors of
     Company;

               (vi)  as a result of, or in connection with, an election of
     directors of Parent, the persons who were directors of Parent before such
     election cease to constitute a majority of the directors of Parent; or

               (vii) RightCHOICE Managed Care, Inc. ceasing to have a class of
     its stock listed and actively traded on a nationally recognized stock
     exchange.

In the event that no single transaction or event has occurred that qualifies as
a Change in Control under the foregoing definition, in determining whether a
Change in Control has occurred, a series of transactions and/or events may be
considered to be a single transaction or event; provided, however, that
elections occurring during no more than eighteen (18) months shall be aggregated
for purposes of determining whether a series of transactions or events qualifies
as a Change in Control under Section 2(E)(v) or 2(E)(vi). If a series of
transactions and/or events is deemed to constitute a single transaction or event
constituting a Change in Control under the preceding sentence, such Change in
Control will be deemed to occur on the date of completion of the last
transaction or event included in the series of transactions and/or events
constituting such Change in Control or such earlier date after the beginning of
such series or transactions and/or events as Executive elects. Any person or
entity that is regularly in the business of lending money may, under the terms
of an agreement executed in connection with extending financing, be granted the
right to enforce covenants requiring certain financial ratios or business
practices to be maintained, so long as such requirements are typical of the
covenants required by lenders generally in connection with financing similar to
that provided in connection with such agreement, without a Change in Control
being deemed to have occured. For purposes of this definition only, no entity
shall be considered a Parent or an Affiliate unless such entity had that status
prior to the transaction or event (or the first in a series of transactions
and/or events aggregated as a single transaction or event pursuant to this
paragraph) that would have constituted a Change in Control.

     F.   Code. "Code" shall have the same meaning as that term is given under
          ----
the Officer Agreement.

     G.   Company. "Company" shall mean RightCHOICE, except that, if any person
          -------
or entity other than RightCHOICE employs Executive and is obligated by
agreement, operation of law or otherwise to abide by and be bound by the
provisions of this Agreement, then "Company" shall mean that person or entity;
provided, however, that the substitution of another person or entity as
"Company" under this Agreement shall not be construed as removing from, or
eliminating with respect to, RightCHOICE or any other person or entity that
subsequently employs Executive and becomes bound by the provisions of this
Agreement, any of the

                                       4
<PAGE>

protections, rights and remedies accruing to the "Company" under the provisions
of Section 4 of this Agreement.

     H.   Date of Termination. "Date of Termination" shall mean the effective
          -------------------
date of Executive's termination of employment. If Executive delivers a Notice of
Termination hereunder to Company, then the Date of Termination shall be thirty

to Company in accordance with Section 6(B) hereof; provided, however, that in
such event Company shall have the right to accelerate such Date of Termination
by written notice of such acceleration delivered or mailed to Executive in
accordance with Section 6(B) hereof. If Company delivers or mails a Notice of
Termination hereunder to Executive in accordance with Section 6(B) hereof, then
the Date of Termination shall be the date specified by Company in such Notice of
Termination.

          ----------------------------
mean the benefits described in Section 3(B) hereof.

     M.   Good Reason. "Good Reason" shall mean the occurrence, without the
          -----------
written consent of Executive and within twenty-four (24) months following a
Change in Control, of any one or more of the following events (provided,
however, that none of the following events shall constitute Good Reason if at
the time of the occurrence of such event, or during the three-month period prior
to such occurrence, there is Cause):

                    (i)  the assignment to Executive of any duties or
          responsibilities inconsistent with Executive's status as a senior

          level of performance, or a change to the long-term incentive formula
          that was applicable to Executive immediately prior to the Change in
          Control that reduces the stock options (or other award) at target
          level of performance;

                     (iii) the relocation of Executive's principal place of
          performing his duties as an employee of the Company to a location in
          excess of seventy-five (75) miles from the location that was,
          immediately prior to the Change in Control, Executive's principal
          place of performing his duties as an employee of Company;

                     (iv)  a material reduction in the benefits and perquisites

     O.   Involuntary Termination. "Involuntary Termination" shall mean the
termination of Executive's employment by action of Company within twenty-four

                                       6

                              SEVERANCE BENEFITS
                              ------------------

     A.   Standard Severance Benefits. No benefits shall be payable to Executive
          ---------------------------
under this Agreement unless and until all conditions specified herein are met,
including, without limitation, the occurrence of a Change in Control with the
necessary subsequent effect on Executive's employment. Prior to the occurrence
of a Change in Control, any severance benefits due to Executive upon termination
of employment with Company will be determined solely under the Officer
Agreement. Executive agrees that, if at any time Executive qualifies for
benefits under this Agreement, the Officer Agreement will terminate
automatically and the terms of the Officer Agreement will be given no further

items in this Agreement are determined with reference to such terms), Executive
will have no rights whatsoever arising under or in connection with the Officer
Agreement, no payment of any benefits provided for in the Officer Agreement will
be made to Executive and this Agreement will constitute the sole and exclusive
authority for payment of severance benefits to Executive. Regardless of anything
to the contrary in the preceding sentence, if at any time Executive begins
receiving Standard Severance Benefits, this Agreement will

                                       7

terminate automatically and its terms will be given no further effect
whatsoever, Executive will have no rights whatsoever arising under or in

          ----------------------------
4(D)(ii) hereof, in the event of Executive's Involuntary Termination or Good
Reason Termination, Company shall pay for outplacement services for Executive of
the type customarily provided by Company to senior executives at the time of
Executive's Involuntary Termination or Good Reason Termination and shall pay
Executive an amount equal to the greater of:

               (i)  two (2) times Executive's Annual Compensation; or

               (ii) an amount equal to:

                    (a) three (3) times Executive's Base Pay plus,

                    (b) for a period of twelve (12) months starting on the Date
               of Termination, an amount equal to the portion of the premiums
               (to the extent such premiums are due) for Executive's health,
               dental, vision and life insurance that is equivalent to the
               portion of the premiums for such coverages that the Company pays
               on behalf of similarly situated executives employed by Company
               during such twelve (12) month period.

Such Executive Severance Benefits will commence as soon as practicable following
the Date of Termination, and will be paid in twenty-four (24) substantially
equal monthly installments, in the case of Executive Severance Benefits under
Section 3(B)(i) above, or in thirty-six (36) monthly installments, in the case
of Executive Severance Benefits under Section 3(B)(ii) above, with the first 12
such installments equaling 1/36th of the amount determined under Section
3(B)(ii)(a) plus 1/12th of the amount determined under Section 3(B)(ii)(b) above
and the remaining such installments equaling 1/36th of the amount determined
under Section 3(B)(ii)(a). Company's obligation to pay the amounts specified in
Section 3(B)(ii)(b) above shall be reduced by any and all amounts Company pays
toward Executive's health, dental, vision and life insurance with respect to
periods after the Date of Termination.

     C.   Suspension or Termination of Severance Benefits: Nonentitlement.
          ---------------------------------------------------------------

               (i)  Dispute. If at any time a party to this Agreement notifies
                    -------
     the other party pursuant to Section 6(B) hereof that one party disputes the
     position of the other party with respect to any provision of this
     Agreement, then Company may at any time elect to suspend some or all
     payments hereunder with respect to Executive (or elect not to

                                       8
<PAGE>

     commence such payments if payments have not yet commenced) until such
     dispute is finally resolved either by mutual written agreement of the
     parties or a binding arbitration award pursuant to Section 6(H) hereof. If
     pursuant to such resolution of the dispute, retroactive payments are to be
     made to Executive or payments representing reimbursements are to be made to
     Company, then unless otherwise provided under such resolution, such
     payments shall bear interest at the rate provided in Section 1274(d)(2)(B)
     of the Code commencing at the time such payments would have been made
     absent dispute (in the case of retroactive payments) or commencing at the
     time such payments were made (in the case of reimbursements).

               (ii)  Subsequent Employment. If at any time while Executive is
                     ---------------------
     entitled to Executive Severance Benefits hereunder, Executive is employed
     (including employment by the Company or an Affiliate, employment by any
     other employer or any form of self-employment) then (a) Company may in its
     discretion at any time following the date of commencement of such
     employment, pay to Executive the aggregate remaining amounts to be paid to
     Executive under Section 3(B)(i) or 3(B)(ii)(a) hereof in a lump sum; and
     (b) payments for outplacement services and payments under Section
     3(B)(ii)(b) hereof shall cease as of the date of commencement of such
     employment, but if payments for outplacement services and/or under Section
     3(B)(ii)(b) are made by Company subsequent to such date then Company may
     withhold the amount of any such payments from the amount otherwise to be
     paid pursuant to Section 3(B)(ii)(a) hereof, and Executive shall pay to
     Company on demand any such excess amount not so withheld, with such excess
     amount to bear interest at the rate provided in Section 1274(d)(2)(B) of
     the Code commencing thirty (30) days after such demand.

               (iii) Disability. If Executive is Disabled during any period
                     ----------
     while Executive is entitled to Executive Severance Benefits hereunder,
     then, during any such period that Executive is Disabled, any amounts
     payable under Section 3(B) hereof during such period shall be reduced (but
     not to less than zero) by the amounts paid or to be paid with respect to
     such period to Executive pursuant to any long-term disability plan
     maintained by Company.

               (iv)  Death. If Executive dies during any period while Executive
                     -----
     is entitled to Executive Severance Benefits hereunder, then a lump sum
     amount equal to the total remaining amounts payable to Executive at the
     time of Executive's death under Section 3(B) hereof shall be paid to
     Executive's Designated Beneficiary; provided, however, that such lump sum
     amount shall be reduced, but not to less than zero, by any amounts payable
     on account of Executive's death to any beneficiary designated by Executive
     other than Company under any Company life insurance program.

                                       9
<PAGE>

               (v)  Criminal Charges. If at any time after Executive Severance
                    ----------------
     Benefits become payable hereunder and prior to the completion of the
     payment of such benefits Executive is charged with a felony, or other crime
     involving moral turpitude, which crime relates to activities of Executive
     occurring during the period Executive was employed by Company or its
     predecessor(s) under this Agreement, then Company may suspend such payments
     until such criminal charge is resolved. Company shall resume payments and
     make any retroactive payments (with interest on such retroactive payments
     at the rate provided in Section 1274(d)(2)(B) of the Code) commencing at
     the time such payments would have been made absent suspension under this
     Section 3(C)(v) after such criminal charge is resolved; provided, however,
     that such payments shall cease and no further payments shall be made at any
     time Executive is convicted of, or enters a guilty plea to, such crime by
     or before a court of competent jurisdiction.

     D.   Limitations on Benefits.
          -----------------------

               (i)  Code Limitations. In the event that the aggregate of any
                    ----------------
     amounts payable to or on behalf of Executive under the Agreement and under
     any other plan, agreement or policy of Company or any Affiliate would
     otherwise result in the imposition of tax under Section 4999 of the Code
     due to an excess parachute payment, as determined by Company's independent
     auditors, then the amounts payable to or on behalf of Executive under the
     Agreement shall be reduced to the extent necessary (but not below zero) so
     that such aggregate amounts shall not be a parachute payment. For purposes
     of determining any limitation under this Section 3(D)(ii): (a) no portion
     of any benefit the receipt or enjoyment of which Executive shall have
     effectively waived in writing shall be taken into account, and (b) the
     value of any non-cash benefit or any deferred payment or benefit shall be
     determined by the Company's independent auditors in accordance with the
     principles of Sections 280G(d)(3) and (4) of the Code. If the Company's
     independent auditors determine that payment that would be a parachute
     payment has been made to Executive hereunder, then the excess of (a) the
     amount of such payment actually made hereunder over (b) the amount that
     could be paid hereunder without any amount payable hereunder being a
     parachute payment, shall constitute a loan by Company to Executive, payable
     to Company upon demand with interest at the rate provided in Section
     1274(d)(2)(B) of the Code commencing as of the date or dates of payment by
     Company of such excess amount.

     E.   General Waiver and Release. Notwithstanding any provision to the
          --------------------------
contrary in the Agreement, Executive acknowledges that in addition to other
conditions set forth in the Agreement, Executive Severance Benefits shall be
conditioned upon the prior execution by Executive of a general waiver and
release (hereinafter referred to as "Waiver") as described in this Section 3(E),
and Executive shall not be eligible for Executive Severance Benefits unless and
until Executive has executed the Waiver within ninety (90) days following the
later of Executive's

                                       10
<PAGE>

termination of employment. The Waiver shall be substantially in the form
attached hereto as Exhibit A and shall generally waive all claims Executive has
or may have against Company or an Affiliate, and any successors or predecessors
thereto, and shall release Company and all Affiliates, and any successors and
predecessors thereto, from all liability with respect to any such claims;
provided, however, that Executive shall not waive, and there shall be no release
with respect to, any claim (other than a claim disputing the validity of this
Section 3(E) or the Waiver) of Executive to enforce any one or more of the
provisions of the Agreement.

                                   SECTION 4
                                   ---------
                             EXECUTIVE'S COVENANTS

permit any Confidential Information to be read, duplicated or copied except in

when the duties of Executive as an employee of the Company no longer require
Executive's possession thereof, or whenever Company shall so request, and, in
any event, will promptly return all such Confidential Information if Executive's
employment with Company terminates and will not retain any copies thereof. For

               (i)  Executive agrees that during the term of Executive's
     employment by Company and for a period consisting of the greater of: (i)
     the period over which any Executive Severance Benefits are to be paid under
     this Agreement (whether or not payment is accelerated hereunder), or (ii)

     term of employment and applicable subsequent period are referred to
     collectively herein as the "Noncompetition Period"), Executive will not
     directly or indirectly, without the express prior written consent of
     Company:

                         (a)  own or have any interest in or act as an officer,

          consultant to or independent contractor of, any person, firm,
          corporation, partnership, business trust, limited liability company or

          geographic market which during the Noncompetition Period is engaged in
          competition in any substantial manner with Company or an Affiliate,
          provided Executive in any such capacity directly or indirectly
          performs services in an aspect of such business which is competitive
          with Company or an Affiliate;

                         (b)  divert or attempt to divert clients, customers or
          accounts of Company which are clients, customers or accounts during
          the Noncompetition Period; or

                         (c)  hire, or attempt to solicit to hire, for any other
          person, firm, company, corporation, partnership, business trust,
          limited liability company or any other entity, whether or not owned
          (in whole or in part) by Executive, any current employee of Company as
          of the time of such hire or attempt to solicit to hire or former
          employee of Company who has been employed by Company within the
          twelve-month period immediately preceding the date of such hire or
          attempt to solicit to hire.

     4(C), Executive acknowledges that Company's geographic market is: (a) the

     the protection of the legitimate business interests of Company.

               (iv)  Executive acknowledges that Executive's experience and
     capabilities are such that, notwithstanding the restrictions imposed in
     this Section 4(C), he believes that he can obtain employment reasonably
     equivalent to his position with Company, and an injunction against any
     violation of the provisions of this Section 4(C) will not prevent Executive
     from earning a livelihood reasonably equivalent to that provided through
     his position with Company.

     D.   Certain Remedies.
          ----------------

               (i)   Recognizing that irreparable injury will result to Company
     in the event of the breach or threatened breach of any of the foregoing
     covenants and assurances by Executive contained in this Section 4, and that
     Company's remedies at law for any such breach or threatened breach will be
     inadequate, if after written notice of breach delivered or mailed to
     Executive in accordance with Section 6(B) hereof Executive takes no
     satisfactory action to remedy such breach and abide by this Agreement, or
     absent such notice in the event such breach cannot be remedied, then
     Company, in addition to such other rights or remedies which may be
     available to it (including, without limitation, recovery of monetary
     damages from Executive), shall be entitled to an injunction, including a
     mandatory injunction, to be issued by any court of competent jurisdiction
     ordering compliance with this Agreement or enjoining and restraining
     Executive, and each and every person, firm or company acting in concert or
     participation with Executive, from the continuation of such breach and, in
     addition thereto, Executive shall pay to Company all ascertainable damages,
     including costs and reasonable attorneys' fees, sustained by Company by
     reason of the breach or threatened breach of said covenants and assurances.

               (ii)  In addition to the remedies described in Section 4(D)(i),
     in the event of a material breach of this Agreement by Executive Company
     shall no longer be obligated to pay any benefits to Executive under this
     Agreement.

               (iii) The covenants and obligations of Executive under this
     Section 4 are each independent covenants and are in addition to and not in
     lieu of or exclusive of any other obligations and duties of Executive to
     the Company, whether express or implied in fact or in law.

                          GENERAL WAIVER AND RELEASE
                          --------------------------

     This General Waiver and Release ("Waiver") is made and entered into by and
among __________________ ("Officer") and RightCHOICE Managed Care, Inc.
including its affiliates, officers, directors, agents and employees (the
"Company").

     WHEREAS, Officer's active employment ended on _______________, 19__ and
Officer wants to begin receiving benefits under the Officer Severance Agreement
("Severance Agreement"), previously entered into between Officer and Company;
and

     WHEREAS, among other conditions, the Severance Agreement specifically
requires Officer to execute this Waiver in order to receive such severance
benefits;

     NOW THEREFORE, for and in consideration of the covenants and undertakings
herein set forth, and for other good and valuable consideration, which each
party hereby acknowledges, it is agreed as follows:

     1.   Officer represents and warrants that, as of the date of this Waiver,
to the best of his knowledge, no circumstances exist or have existed which could
result in Officer's termination for Cause or a suspension or termination of
benefits under the Severance Agreement as provided in the Severance Agreement.
Regardless as to the reason for termination, Officer agrees not to apply for
rehire at the Company, it's subsidaries, affiliates or parent.

     2.   Based on the representations and warranties provided by Officer in
clause No. 1 above, Company hereby acknowledges that Officer's termination of
employment with Company
<PAGE>

qualifies as either an Involuntary Termination or a Proper Reason Termination
within the meaning of the Severance Agreement.

     3.   Officer agrees that he will not in any way disparage the Company or
its parent, subsidiary or other affiliated entities, or their respective current
or former officers, directors and/or employees. Officer further agrees that he
will not make or solicit any comments, statements or the like to the media or to
others that may be considered to be derogatory or detrimental to the good name
or business reputation of any of the aforementioned parties or entities. Company
specifically reserves the right to suspend or terminate benefits under the
Severance Agreement, if, subsequent to the execution of this Waiver, Company
becomes aware of information, or an event occurs, which indicates noncompliance
with this section or which would otherwise result in a suspension or termination
of such benefits in accordance with the provisions of the Severance Agreement.

     4.   Officer agrees to, and does hereby, remise, release, and forever
discharge Company, and each and every one of its parent, subsidiary and other
affiliated entities, and their respective agents, officers, executives,
employees, successors, predecessors, attorneys, trustees, directors, and assigns

"Company"), from and with respect to all matters, claims, charges, demands,
damages, causes of action, debts, liabilities, controversies, judgments, and
suits of every kind and nature whatsoever, foreseen or unforeseen, known or
unknown, which have arisen or may arise between Officer and Company including,
but not limited to, those in any way related to Officer's employment and/or
termination.

other charge, claim, complaint, or action to any agency, court, organization, or

to take such action on his behalf) against Company arising out of any actions or
non-actions that have occurred on the part of Company. Such claims, complaints,

(s) 2101, the Civil Rights Act of 1871, 42 U.S.C. (S) 1981, the Family and
Medical Leave Act of 1993, 19 U.S.C. (S) 2601 et seq., the Missouri Human Rights
                                              --
Act, (S) 213.010 RSMo et seq., the Missouri Workers Compensation law, (S) 287
                      ------
RSMo et seq., the Missouri Service Letter Statute, (S) 290.140 RSMo, or any
     ------
other federal, state, or local statutes or ordinances. Officer further agrees
that in the event that any person or entity should bring such a charge, claim,

                                       3
<PAGE>

complaint, or action on his behalf, he hereby waives and forfeits any right to
recovery under said claim and will exercise every good faith effort to have such
claim dismissed. Officer affirms that he has no charge, claim, complaint or
action against Company pending in any government agency or court.

     Notwithstanding the above, Officer shall not waive, and there shall be no
release with respect to, any claim (other than a claim disputing the validity of
section 3(D) of the Severance Agreement or the provisions of this Waiver) of
Officer to enforce any one or more of the provisions of the Severance Agreement.

     5.   Pending Lawsuit. Officer agrees to make himself available upon three
          ---------------
days notice from Company, or its attorneys, to be deposed, to testify at a
hearing or trial or to accede to any other reasonable request by Company in
connection with any lawsuit either currently pending against Company or any
lawsuit filed after Officer's separation that involves issues relating to
Officer's job responsibilities or to decisions made by him during his employment
with Company.

     6.   Injunctive Relief. In the event of a breach or threatened breach of
          -----------------
any of Officer's duties and obligations under this Waiver, Company shall be
entitled, in addition to any other legal or equitable remedies Company may have
in connection therewith (including any right to damages that Company may
suffer), to a temporary, preliminary and/or permanent injunction restraining
such breach or threatened breach.

     7.   Invalidity of Provisions. In the event that any provision of this
          ------------------------
Waiver is adjudicated to be invalid or unenforceable under applicable law, the
validity or enforceability of the remaining provisions shall be unaffected. To
the extent that any provision of this Waiver is

                                       4
<PAGE>

adjudicated to be invalid or unenforceable because it is overbroad, that
provision shall not be void but rather shall be limited only to the extent
required by applicable law and enforced as so limited.

     8.   Knowing and Voluntary Waiver. Officer hereby acknowledges that he is
          ----------------------------
entering into this Waiver knowingly and voluntarily and understands that he is
waiving valuable rights he may otherwise be entitled to.

     9.   Governing Law. This Waiver shall be construed and governed by the laws
          -------------
of the State of Missouri, excluding its choice of law provisions.

     10.  Gender. Provisions in this Waiver used in the masculine gender shall
          ------
also include the feminine gender, as appropriate.

     11.  Successors and Assigns. This Waiver shall be binding upon and inure to
          ----------------------
the benefit of any successors or assigns of Officer or Company.

     12.  Defined Terms. Unless otherwise defined herein, capitalized terms used
          -------------
herein shall have the meanings assigned to them in the Severance Agreement.

     13.  Miscellaneous. The foregoing Waiver constitutes the entire agreement
          -------------
among the parties and there are no other understandings or agreements, written
or oral, among them on this subject. Separate copies of the document shall
constitute original documents which may be signed separately but which together
will constitute one single agreement. This Waiver will not be binding on any
party, however, until signed by all parties or their representatives.
