F.   PERSONNEL CHANGES DURING THE PLAN PERIOD

     Employment status changes by a Participant during the Plan Period shall be
     treated in the following manner:

     1.   NEW HIRE, TRANSFER WITHIN THE COMPANY, PROMOTION, ACQUISITIONS.  A
          newly hired employee, an employee transferred within the Company or
          promoted during the Plan Period to a position qualifying for
          participation, or employees deemed eligible by the Administrator as a
          result of an acquisition or merger, may be recommended for a pro rata
          Bonus based upon the percentage of the Plan Period the employee is in
          an eligible position.  To be considered, the employee must hold a
          qualifying position for at least one (1) calendar quarter during the
          Plan Period.  Employees newly hired (including as a result of an
          acquisition or merger) or newly promoted after October 1 of any Plan
          Period shall not be eligible for a Bonus for the relevant Plan Period.

      2.  REINSTATEMENTS/REHIRES.  An employee who terminates, either
          voluntarily or involuntarily, and is subsequently rehired may be
          eligible for a pro rata Bonus, provided that the reinstated employee
          held a qualifying position in the relevant Plan Period for at least
          thirteen weeks.  To be eligible for a Bonus payout, the employee must
          be an active employee at the time the Bonus is paid.  The decision to
          pay a Bonus in this situation shall be made at the sole discretion of
          the Administrator.

      3.  DEMOTION.  No bonus will be paid to an employee who has been demoted
          during the Plan Period because of performance.  If the demotion is due
          to an organization change, or is on a voluntary basis, a full or a pro
          rata Bonus may be made provided the employee is otherwise qualified
          for a Bonus as stated in Section E.  The decision to pay a Bonus in
          this situation shall be made at the sole discretion of the
          Administrator and the Bonus, if any, will normally be paid at the time
          set forth in Section H.

      4.  TERMINATION AS A RESULT OF DEATH, PERMANENT DISABILITY, RETIREMENT OR
          4TH QUARTER REDUCTION IN FORCE.  Participants who terminate employment
          prior to the payment of a Bonus, as a result of death, permanent
          disability or retirement, or as a result of a reduction in force
          during the 4th quarter of the Plan Period may receive a pro rata Bonus
          at the sole discretion of the Administrator.  These awards, if any,
          will be paid at the time set forth in Section H.

      5.  OTHER TERMINATIONS.  A Participant or other employee who is
          involuntarily terminated and/or voluntarily resigns from the Company
          before the Bonus is paid for any Plan Period will not be eligible to
          receive a Bonus for such Plan Period, unless he/she is eligible for an
          award due to reinstatement/rehire.

      6.  LEAVE OF ABSENCE.  An employee whose status as an active employee is
          changed during the Plan Period or before the Bonus is actually paid
          due to a leave of absence may be considered for a full or pro rata
          Bonus payment if the employee has been a Plan Participant 


                                      3
<PAGE>


          for at least one (1) calendar quarter and is actively employed as of
          the end of the Plan Period and at the time the Bonus is paid.
          Normally, leaves of absence of thirty (30) days or

     less will not impact the Bonus payment.  Leaves of absence greater than
     thirty (30) days may result in a pro-rated bonus.  The decision to pay such
     a Bonus in these situations will be made at the sole discretion of the
     Administrator and the Bonus, if any, will be paid at the time set forth in
     Section H.


G.   DETERMINATION OF BONUS AND ELIGIBILITY FOR PAYMENT

     After the completion of the Plan Period (and preliminary financial
     statements are available), the Bonuses shall be calculated by the
     Administrator according to the Plan Guidelines.  Only employees actively
     employed with the Company on the date the Bonuses are paid, whose overall
     performance appraisal for the Plan Period is "Achieves Expectations" or
     higher (or similar classification used by the Company in the assessment of
     employee performance) are eligible for payment unless otherwise determined
     by Section F.


H.   PAYMENT OF INDIVIDUAL BONUSES

     1.   TIMING AND FORM.  Unless otherwise determined by the Administrator,
          Bonuses will be paid on or before the Company's normally occurring pay
          date closest to March 10th of the calendar year following the Plan
          Period.  Bonuses will be paid in a lump sum and in cash.

     2.   WITHHOLDING.  The Company will deduct the amounts required by law to
          be withheld for federal, state and local income and employment taxes
          for all Bonus payments.  In addition to such tax withholding, eligible
          participants in the Company's 401(k) plan will have an amount deducted
          from his or her Bonus payment equal to the elected contribution amount
          in effect at the time of Bonus payment.  The Company may provide a
          match of the 401(k) contribution to the extent then provided under the
          terms of the WellPoint Salary Deferral Savings Plan.

     3.   PLAN FUNDING.  Aggregate payouts under the Plan will be based upon the
          Company achieving its internal projections for earnings per share.
          Business group and business unit bonus pools will be allocated based
          on performance against specific goals.  Aggregate payouts under the
          Plan will be funded based on the following performance scale:

                80% of Plan                           70%
                100% of Plan                         100%
                110% of Plan or greater              150%
</TABLE>

     4.   SOURCE.  All payments under the Plan will be paid by the Company (on
          behalf of itself and its Affiliates) from its general assets.  No
          person will have any right or interest under the Plan 


                                      4

          that is superior in any manner to the right of any other general and
          unsecured creditor of the Company.

I.   IMPACT ON BENEFIT PLANS

     To the extent permitted by law, and the terms of the Company's benefit
     plans, Bonus payments under the Plan will be treated as compensation for
     purpose of a Plan participant's benefit calculations. Bonus payments will
     not affect a participant's (a) coverage under any Company group insurance
     plan; or (b) the contributions or the benefits under any group plan or any
     kind heretofore or hereafter in effect, under which the availability or
     amount of benefits is related to compensation.


J.   TERMINATION OR AMENDMENT OF THE PLAN

     1.   GENERAL PROVISIONS.  The CEO, with the approval of the Compensation
          Committee of the Board of Directors, may at any time terminate or make
          any amendment to the Plan without prior notice to Participants.  There
          can be no oral modifications to the Plan and only modifications in
          writing will be honored.

     2.   DISCRETIONARY NATURE OF THE PLAN.  Notwithstanding anything else in
          this Plan, Bonus awards are paid at the discretion of the
          Administrator, and are not a part of a Participant's salary.  The
          Administrator retains the discretion to increase awards of the total
          bonus opportunity of all participants, as well as to decrease or
          eliminate awards to individuals if the Administrator deems such action
          is appropriate.

     3.   EXTRAORDINARY TRANSACTIONS.  Without the consent of any Participant,
          the CEO may, with the agreement of the Compensation Committee of the
          Company's Board of Directors, modify the Plan at any time to reflect
          extraordinary transactions or occurrences affecting the Company (e.g.,
          changes to the capital structure or other significant reorganization
          of the Company, divestiture of a subsidiary, acquisition or
          discontinuance of a material business or product line, changes in
          accounting procedures/policies, or governmental changes in the
          financing of health care delivery, etc.).  Any such modification will
          be designed to prevent the dilution or enlargement of benefits under
          this Plan.


K.   MISCELLANEOUS

     Nothing in this Plan will be construed as a guarantee of a Bonus or as an
     accrued right to receive a Bonus or a portion of a Bonus or a Bonus
     payment.  Nothing in this Plan shall be construed as creating a contract of
     employment.  No Bonus payable under this Plan may be alienated or assigned.
