law, to (i) establish, amend, suspend or waive such rules and regulations and

sole discretion of the Committee, (y) may be made at any time and (z) shall be
final, binding and conclusive for all purposes on all persons, including, but
not limited to, Participants and their legal representatives and beneficiaries,
and employees of the Company.
 
         (b)      Determinations Made Prior to Each Performance Period. At any
time ending on or before the 90th calendar day of each Performance Period, the
Committee shall:
 
                  (i)      with respect to Annual Incentive Awards, (A)
         designate all Participants and their Target Awards for such Performance
         Period, and (B) establish one or more Performance Thresholds, based
         solely on EPS; and
 
                  (ii)     with respect to Performance Awards, (A) designate all
         Participants, their target and maximum awards for such Performance
         Period, and (B) establish the objective performance factors for each
         Participant for that Performance Period on the basis of one or more of
         the criteria set forth in Section 6(a) below.
 
         (c)      Certification. Following the close of each Performance Period
and prior to payment of any amount to any Participant under the Plan, the
Committee must certify in writing:
 
                  (i)      with respect to Annual Incentive Awards, (A) the
         Company's Earnings and EPS for that Performance Period and (B) as to
         the attainment of all other factors upon which any payments to a
         Participant for that Performance Period are to be based; and
 
                  (ii)     with respect to Performance Awards, as to the
         attainment of all factors (including the performance factors for a
         Participant) upon which any payments to a Participant for that
         Performance Period are to be based.
 
SECTION 5.        ANNUAL INCENTIVE AWARDS.
 
         From time to time, the Committee may grant annual incentive awards
under the Plan payable to Participants in cash (an "Annual Incentive Award").
Annual Incentive Awards shall be granted in accordance with the following
provisions:
 
         (a)      Formula. In the event that the Company's EPS for a Performance
Period is equal to or exceeds a designated Performance Threshold for that
Performance Period, then each Participant shall receive an Annual Incentive
Award for that Performance Period in an amount not greater than
 
                                       3
 
<PAGE>
 
                  (i)      the Participant's Base Salary for the Performance
                           Period, multiplied by
 
                  (ii)     the Participant's Target Award for the Performance
                           Period;
 
provided, however, that in the event that the Company's EPS for a Performance
Period exceeds the highest designated Performance Threshold for that Performance
Period, then each Participant shall receive an Annual Incentive Award for that
Performance Period in an amount not greater than the Maximum Annual Incentive
Award for that Performance Period.
 
         (b)      Limitations.
 
                  (i)      Discretionary Reduction. The Committee shall retain
         sole and full discretion to reduce by any amount the Annual Incentive
         Award otherwise payable to any Participant under this Plan.
 
                  (ii)     Continued Employment. No Annual Incentive Award shall
         be paid to a Participant who is not actively employed by the Company at
         the time the Annual Incentive Award otherwise would be paid except in
         the case of retirement, death or permanent disability. If a Participant
         retires before the end of a Performance Period or after the end of a
         Performance Period but before an Annual Incentive Award is paid, the
         Committee may, in its discretion, determine that the Participant shall
         be paid a pro rated portion of the Annual Incentive Award that the
         Participant would have received but for such retirement. If a
         Participant dies or becomes permanently and totally disabled before the
         end of a Performance Period or after the end of a Performance Period
         but before an Annual Incentive Award is paid, the Committee may, in its
         discretion, determine that the Participant (or, in the case of death,
         the Participant's estate) shall be paid a pro rated portion of the
         Annual Incentive Award that the Participant would have received but for
         such death or disability. The Committee shall determine the
         Participant's date of disability in a manner consistent with Company
         practices.
 
                  (iii)    Maximum Payments. No Participant shall receive an
         Annual Incentive Award under this Plan for any Performance Period in
         excess of the Maximum Annual Incentive Award for that Performance
         Period.
 
         (c)      Payment of Annual Incentive Award. Subject to any deferred
compensation election pursuant to any such plans of the Company applicable
hereto, benefits shall be paid to the Participant in cash as soon as
administratively feasible upon the completion of a Performance Period, after the
Committee has certified that the Performance Threshold has been attained,
determined the Maximum Annual Incentive Award for that Performance Period and
made the other certifications provided for in Section 4(c)(i) hereof.
 
SECTION 6.        PERFORMANCE AWARDS.
 
         From time to time, the Committee may grant Performance Awards under the
Plan payable in cash or in shares of the Company, other securities or other
property (a "Performance Award"). Performance Awards that are payable in shares
of the Company, other securities or other property shall be payable pursuant to
the UnitedHealth Group Incorporated 2002 Stock Incentive Plan. Performance
Awards shall be "qualified performance-based compensation"
 
                                       4
 
<PAGE>
 
within the meaning of Section 162(m) of the Code. Notwithstanding any other
provision of this Plan to the contrary, the following additional requirements
shall apply to all Performance Awards made to any Participant under this Plan:
 
         (a)      Business Criteria. The business criteria to be used for
purposes of establishing performance goals for Performance Awards, the
attainment of which may determine the amount and/or vesting with respect to
Performance Awards, will be selected from the following alternatives (unless
and until the Committee proposes for shareholder approval and the Company's
shareholders approve a change in such criteria), each of which may be based on
absolute standards or comparisons versus specified companies or groups of
companies and may be applied at individual or various organizational levels
(for example, the Company as a whole or identified business units, segments or
the like): revenue growth, Return on Equity, operating cash flows, Earnings per
Share, and operating margin.
 
         In the event that Code Section 162(m) or applicable tax and/or
securities laws change to permit Committee discretion to alter the governing
performance measures without disclosing to shareholders and obtaining
shareholder approval of such changes and without thereby exposing the Company to
potentially adverse tax or other legal consequences, the Committee shall have
the sole discretion to make such changes without obtaining shareholder approval.
 
         (b)      Target and Range; Maximum Performance Award. The target and
range of a Participant's possible Performance Awards established by the
Committee shall be between zero and 300% of the Participant's average base
compensation. For this purpose, average base compensation shall be the
Participant's total salary earned during the applicable Performance Period (or
such lower amount as determined by the Committee) divided by the number of years
in the Performance Period. The maximum bonus which may be paid to any
Participant pursuant to any Performance Award with respect to any Performance
Period shall not exceed $10,000,000.
 
         (c)      Payment of Performance Awards. Performance Awards shall be
paid no later than three months following the conclusion of the applicable
Performance Period. The Committee may, in its discretion, reduce the amount of a
payout otherwise to be made in connection with a Performance Award, but may not
exercise discretion to increase such amount. If permitted by applicable law,
payments of Performance Awards may be deferred into the Company's Executive
Savings Plan in accordance with rules established by the Committee.
 
         (d)      Certain Events. No Performance Award shall be paid to a
Participant who is not actively employed by the Company at the time the
Performance Award otherwise would be paid except in the case of retirement as
provided for in (e) below, death or disability as provided for in (f) below, or
in the event of a Change in Control as provided for in (g) below.
 
         (e)      If a Participant retires before the end of a Performance
Period or after the end of a Performance Period but before a Performance Award
is paid, the Committee may, in its discretion, determine that the Participant
shall be paid a pro rated portion of the Performance Award that the Participant
would have received but for such retirement. In such event, (i) the pro
rationing shall be based on the portion of such Performance Period prior to the
Participant's retirement, and (ii) the measurement of Company and Participant
performance shall be based on
 
                                       5
 
<PAGE>
 
performance through the end of the fiscal year of the Company which ends closest
to the Participant's date of retirement. The Committee shall determine the
Participant's date of retirement in a manner consistent with Company practices.
Any such pro rated Performance Award shall be paid at the same time as other
Performance Awards with respect to the applicable Performance Period.
 
         (f)      If a Participant dies or becomes permanently and totally
disabled before the end of a Performance Period or after the end of a
Performance Period but before a Performance Award is paid, the Committee may, in
its discretion, determine that the Participant (or, in the case of death, the
Participant's estate) shall be paid a pro rated portion of the Performance Award
that the Participant would have received but for such death or disability. In
such event, (i) the pro rationing shall be based on the portion of such
Performance Period prior to the Participant's date of death or disability, and
(ii) the measurement of Company and Participant performance shall be based on
performance through the end of the fiscal year of the Company which ends closest
to such date. The Committee shall determine the Participant's date of disability
in a manner consistent with Company practices. Any such pro rated Performance
Award shall be paid at the same time as other Performance Awards with respect to
the applicable Performance Period.
 
         (g)      If a Change in Control (as defined below) occurs during a
Performance Period or after the end of a Performance Period but before a
Performance Award is paid, the Company or its successor shall pay each
Participant a pro rated portion of the maximum Performance Award for which such
Participant is eligible with respect to each such Performance Period. Such pro
rationing shall be based on the proportion of each such Performance Period
through the date of such Change in Control. Any such Performance Awards shall be
paid within 90 days of the occurrence of the event constituting such Change in
Control, or, if a timely deferral election is then in effect, shall be deferred
into the Company's Executive Savings Plan. Any such Performance Award shall be
paid regardless of whether the Participant is actively employed by the Company
at the time the Performance Award is to be paid.
 
"Change in Control" means the occurrence of any of the following events:
 
                  (i)      The acquisition by any person, entity or "group,"
         within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities

         or any employee benefit plan of the Company and/or one or more of its
         affiliates, of beneficial ownership (within the meaning of Rule 13d-3
         promulgated under the Securities Exchange Act of 1934) of 20% or more
         of either the then outstanding shares of the Company's Common Stock or

                  (ii)     Individuals who, as of January 1, 2002 constitute the

         becoming a Director subsequent to January 1, 2002 whose nomination for
 
                                       6
 
<PAGE>
 
         election was approved in advance by a vote of at least three-quarters
         of the Continuing Directors (other than a nomination of an individual
         whose initial assumption of office is in connection with an actual or
         threatened solicitation with respect to the election or removal of the
         Directors of the Company, as such terms are used in Rule 14a-11 of
