relationships, and the confidential information UnitedHealth Group has
developed about its customers, providers, products, operations, and services.
As of the Effective Date (as defined in Section 3(a)), this Agreement
supersedes that certain Employment Agreement, effective as of January 1,
1996, and any prior similar agreement or agreements between Executive and

1.  EMPLOYMENT.  UnitedHealth Group hereby employs Executive to serve as its
Chief Executive Officer. Executive shall, during the term of his employment
hereunder and subject to the supervision and control of the Board of

duties, have such power, and exercise such supervision and control with
regard to the business of UnitedHealth Group as are commonly associated with
or appropriate to the office of Chief Executive Officer, including, but not
limited to, the day-to-day general management, supervision and control of all
businesses and operations of UnitedHealth Group and its subsidiaries. In
furtherance thereof, Executive shall report to the Board of Directors, and
all other senior executives of UnitedHealth Group and its subsidiaries shall
report to Executive or as Executive may direct. In addition, Executive shall
perform such other duties of a senior executive nature as the Board of
Directors and Executive from time to time determine to be mutually
acceptable. Executive accepts such employment on the terms and conditions set

         (a)  BASE SALARY. Executive shall initially be paid a minimum base
              annual salary in the amount of $1,600,000 payable bi-weekly. From
              time-to-time the Board of Directors shall review Executive's
              performance and shall consider increasing Executive's
              compensation. Effective on each succeeding January 1 during the

              shares of UnitedHealth Group's Common Stock (the "Annual

              dates as Executive requests by oral notification to the Chair of
              the Compensation and Human Resources Committee (with such
              notification confirmed promptly in writing).  To the extent
              Executive has not otherwise requested the issuance of Annual
              Options representing the right to purchase 325,000 shares in any
              year, Annual Options representing such amount shall be issued as
              of the last business day of such year. The exercise price for the
              Annual Options shall be the closing price for UnitedHealth Group
              Common Stock on the date of issuance. Each Annual Option issued
              pursuant to this Section 2(b) shall vest over a period of four
              years at the rate of 25 percent per year on January 1 of each
              year following the grant of such option, subject to earlier
              vesting as otherwise provided in Section 3 of this Agreement.
              Each Annual Option shall be subject to the terms and conditions
              of UnitedHealth Group's Amended and Restated 1991 Stock and
              Incentive Plan, or any substitute or similar successor plan
              (the "Stock Plan"). Notwithstanding the foregoing provisions of
              this Section 2(b), Executive shall be eligible to receive
              additional awards of nonqualified options, as determined by the
              Board of Directors, in accordance with the normal practices of
              UnitedHealth Group for successful performance.

         (c)  SPECIAL STOCK OPTION GRANT. In addition to the Annual Options
              contemplated by Section 2(b), Executive shall also receive an
              option (the "Special Option") to purchase 1,000,000 shares of
              UnitedHealth Group Common Stock. The Special Option shall be
              substantially in the form of Exhibit 2(c) and shall be subject to
              the terms and conditions of the Stock Plan. The exercise price of
              the Special Option shall be $40.125 per share subject to
              adjustment as provided in the Stock Plan. The Special Option will
              expire on the tenth anniversary of its issuance. The Special
              Option will become exercisable on the ninth anniversary of its
              issuance, subject to acceleration upon the occurrence of certain
              performance events as specified in the Special Option.

              in UnitedHealth Group's incentive bonus and other bonus plans and
              shall be eligible to receive grants or awards pursuant to

              accordance with the terms and conditions of those plans and on a
              basis consistent with that customarily provided for senior
              officers at the highest level of UnitedHealth Group. For purposes
              of the Company's Management Leadership Results Plan or any
              substitute or similar successor plan, Executive's target incentive

         (e)  SPECIAL BONUS. In recognition of Executive's strategic
              accomplishments over the past several years, including Executive's
              leadership in implementing the Company's realignment, in making
              successful startup investments in the health care field, in
              augmenting UnitedHealth Group's senior executive management and
              creating leadership succession, Executive shall be entitled to
              receive a special one-time bonus in the amount of $2,600,000 (the
              "Special Bonus"). The Special Bonus shall be paid in cash or
              UnitedHealth Group Common Stock, as Executive elects, upon
              reasonable notice to the Company. If Executive elects to be paid
              in Common Stock, the shares shall be valued at their closing price
              on the date of payment. The Special Bonus shall be paid on January
              4, 2000, subject only to Executive's continued employment as of
              such date.

         (f)  EMPLOYEE BENEFITS. Executive shall be eligible to participate in

              without limitation, any life, health, dental, short-term and
              long-term disability insurance coverage and any retirement or
              savings plans, in accordance with the terms and conditions of
              those plans and on a basis consistent with that customarily
              provided for senior officers at the highest level of UnitedHealth
              Group. Executive shall also receive other benefits consistent with
              his office and position, which benefits shall include, without
              limitation, an allowance to be determined periodically by the
              Chair of the Compensation and Human Resources Committee, on behalf
              of the Committee, and acceptable to Executive, for security
              considerations (such as home and personal security) and for tax
              and financial planning expenses. Executive may utilize any
              UnitedHealth Group aircraft for Executive's personal business up
              to such amount as represents an income tax benefit to the
              Executive of not more than 10% of Executive's then current base
              salary pursuant to Section 2(a). Executive shall be responsible
              for the payment of all income taxes payable by Executive as a
              result of the personal use of UnitedHealth Group aircraft.

</TABLE>

              Executive will be 100 percent vested in such benefit as of January
              1, 1999. The supplemental benefit shall be paid as a joint and
              survivor annuity, and Executive's Spouse (as hereinafter defined)
              shall be entitled to a benefit, at no cost to Executive, equal to
              50 percent of the benefit payable to Executive upon termination of
              this Agreement. Provided, however, if Executive dies while
              actively employed, his Spouse shall receive a survivor annuity as
              if Executive had terminated this Agreement the day before his
              death. Executive shall have the option to convert such annuity to
              a lump sum payment or such other actuarial equivalent optional
              form of payment if Executive makes an irrevocable election at
              least one year prior to termination of this Agreement or if less
              than one year prior to termination of this Agreement if such
              election is agreeable to UnitedHealth Group in its sole
              discretion. The actuarial equivalent value of any optional form of
              benefit shall be determined on the basis of an interest rate of 4%
              per annum and such other actuarial assumptions as are reasonable
              and agreeable to the Executive and UnitedHealth Group. The
              supplemental benefit shall be payable in accordance with Section 3
              or as the parties otherwise agree. For purposes of this section,
              "Spouse" means the person to whom Executive was legally married on
              the date of Executive's death. If the age difference between
              Executive and Spouse exceeds five years, the benefit payable to
              the Spouse shall be actuarially determined as if the age
              difference between Executive and Spouse were five years.

         (h)  VACATION AND ILLNESS. Executive shall be entitled to paid vacation
              and sick leave benefits each year in accordance with UnitedHealth
              Group's then-current policies and on a basis consistent with that
              customarily provided for senior officers at the highest level of
              UnitedHealth Group.

         (i)  ADDITIONAL INSURANCE. In addition to any other insurance to which
              Executive is entitled to under Section 2(f), UnitedHealth Group
              shall provide and pay for, and Executive shall own, a term life
              insurance policy on Executive in an amount equal to $5,500,000,
              which policy shall include an option for Executive to purchase, at
              Executive's expense, additional term life insurance on Executive
              in an amount equal to $3,200,000, and an individual supplemental
              long term "own occupation" disability insurance policy, which may
              be self-

                                          4

              insured by UnitedHealth Group, providing for monthly disability
              income payments to Executive equal to his then-applicable monthly
              pro rata annual base salary reduced by any monthly payments to
              Executive under other individual or group disability income plans
              or policies provided and paid for by UnitedHealth Group. The
              monthly disability income payments to Executive shall begin at
              such time as Executive becomes Permanently Disabled as defined
              in Section 5(a) and shall continue until Executive ceases to be
              disabled, until five years have elapsed, or until Executive
              reaches age 65. UnitedHealth Group shall compensate Executive
              on an after-tax basis for any additional income taxes payable by
              Executive as a result of UnitedHealth Group's payment of
              premiums with respect to the insurance policies described in this
              subsection.

                           the event of any anticipated tax law change during
                           the payment period that would increase Executive's
                           taxes on such income, Executive may elect to take and
                           receive his remaining compensation under this Section
                           3(d)(i), discounted at an interest rate of 4% per
                           annum to the present value thereof, in a single lump
                           sum payable within thirty days after written request
                           therefor setting forth such anticipated tax law
                           change.

                  (ii)     The percentage of Cash Compensation paid pursuant to
                           the Supplemental Employee Retirement Plan
                           contemplated by Section 2(g) shall be determined as
                           of, and payments under such plan shall commence on,
                           the third anniversary of the termination date as if
                           Executive had been continuously employed by
                           UnitedHealth Group through such third anniversary.

                  (iii)    Executive shall be entitled to continue participation
                           in the health care coverage as provided in Section
                           3(j) below and in all other life insurance or other
                           employee benefit plans of UnitedHealth Group
                           established under Section 2(f) of this Agreement.
                           UnitedHealth Group shall for a period of thirty-six
                           months following the effective date of the
                           termination (A) continue to pay disability coverage
                           premiums or provide disability coverage on a
                           self-funded basis for Executive and his dependents
                           with UnitedHealth Group and Executive sharing the
                           costs associated with such coverage as if Executive
                           were still actively employed by UnitedHealth Group,
                           and (B) maintain and pay the premiums with respect
                           to the additional insurance policies provided for in
                           Section 2(i). Executive shall continue to receive
                           health care coverage as provided in Section 3(j) of
                           this Agreement. If Executive cannot be covered under
                           any of UnitedHealth Group's group plans or policies,
                           UnitedHealth Group shall reimburse Executive for his
                           full cost of obtaining comparable alternative group
                           or individual coverage elsewhere, less any
                           contribution that Executive would have been required
                           to make under UnitedHealth Group's group plans or
                           policies. Executive shall receive any benefits
                           payable under Section 2(f) of this Agreement within
                           sixty days of such termination.

                  (iv)     Any vesting requirements or other conditions that an
                           employee or participant complete a longer period of
                           service or employment as shall otherwise theretofore
                           pertain to any of Executive's rights or

                           the extent vested shall continue to be exercisable in
                           accordance with their terms for a period of up to
                           seventy-two months after termination of Executive's
                           employment subject to earlier termination upon

                           independent public accounting firm. In determining
                           the amount of excise tax which would be payable by
                           Executive pursuant to Section 4999 of the Code, such
                           accounting firm shall take into consideration and
                           apply all non-includible, excludable and exempt
                           amounts of compensation in accordance with Section
                           280G of the Code. The parties shall cooperate fully
                           by promptly providing such accounting firm all
                           information required to complete such
                           determinations. Such determinations shall be set
                           forth in a written statement and analysis thereof
                           issued by such accounting firm which shall be
                           promptly finished to and shall be binding upon the
                           parties. In the event Executive is subject to any
                           audit with respect to the amount of such excise
                           taxes, Executive and UnitedHealth Group will mutually
                           cooperate in contesting such audit; provided that
                           UnitedHealth Group will pay the cost of such contest
                           and will reimburse Executive on an after tax basis
                           for any additional excise taxes payable as a result
                           of such audit and for any income taxable to Executive
                           as a result of UnitedHealth Group paying the cost of
                           such audit and any additional excise taxes. In the
                           event any such audit results in a refund of excise
                           taxes paid, Executive will turn over the refund to
                           UnitedHealth Group less any income taxes incurred by
                           Executive in respect of the receipt of the refund.

         (e)  TERMINATION OF EMPLOYMENT BY EXECUTIVE FOLLOWING A CHANGE IN
              CONTROL. If a Change in Control of UnitedHealth Group occurs and
              either (y) within a period following such Change in Control of six
              months (or such lesser period of time as is acceptable to the
              Company or its successor) and twelve months Executive terminates
              employment under Section 3(b), or (z) at anytime after a Change of
              Control, Executive's employment with UnitedHealth Group is
              terminated by UnitedHealth Group under Section 3(b)(ii) without
              Cause prior to the end of the term of this Agreement or by
              Executive for Good Reason under Section 3(b)(vi) prior to the end
              of the term of this Agreement, then upon termination of
              Executive's employment:

                  (i)      For a period of thirty-six months following the
                           effective date of the termination of employment
                           Executive shall receive biweekly payments equal to
                           1/26 of Executive's annualized Cash Compensation. In
                           the event of any anticipated tax law change during
                           the payment period that would increase Executive's
                           taxes on such income, Executive may elect to take and
                           receive his remaining compensation under this Section
                           3(e)(i), discounted at an interest rate of 4% per
                           annum to the present value thereof, in a single lump
                           sum payable within thirty days after written request
                           therefor setting forth such anticipated tax law
                           change.

                           3(j) below and in all other life insurance or other

                           and conditions of those plans. UnitedHealth Group
                           shall for a period of thirty-six months following the
                           effective date of the termination (A) continue to pay
                           disability coverage premiums or provide disability
                           coverage on a self-funded basis for Executive and his
                           dependents with UnitedHealth Group and Executive
                           sharing the costs associated with such coverage as if
                           Executive were still actively employed by

                           provided in Section 3(j) of this Agreement. If

                           Group's group plans or policies, UnitedHealth Group
                           shall reimburse Executive for his full cost of

                           employee or participant complete a longer period of
                           service or employment as shall otherwise theretofore

                           Option granted pursuant to Section 2(c) which shall
                           already have been fully vested and exercisable upon

                           case may be, subject to accrual, payment or exercise
                           in full, or transfer (unless expressly
                           non-transferable) without regard to such

                           Executive and shall provide Executive with use of
                           Company aircraft for personal business to the same
                           extent Executive could so use such aircraft for
                           personal business prior to termination, all for a
                           period of thirty-six months following termination of
                           employment.

                  (vii)    All accrued and unpaid vacation to the date of
                           termination shall be paid to Executive.

                  (viii)   In the event the payments, the acceleration of
                           vesting of stock options or the provision of any
                           other benefits under this Agreement or the Special
                           Option are "parachute payments" within the meaning
                           of, and the regulations, rulings and procedures
                           under, Sections 280G and 4999 of the Code or other

                           Code at any time applicable thereto, and become
                           subject to excise taxes under Section 4999 of the
                           Code, UnitedHealth Group will pay Executive the
                           amount of such excise taxes plus all federal, state,
                           and local taxes applicable to UnitedHealth Group's
                           payment of such excise taxes, including any
                           additional excise taxes due under Section 4999 of the
                           Code with respect to payments made pursuant to this
                           Section 3(e)(viii). All determinations required by
                           this Section 3(e), upon termination of Executive's
                           employment and at UnitedHealth Group's sole expense,
                           shall forthwith be made by UnitedHealth Group's
                           regularly engaged independent public accounting firm.
                           In determining the amount of excise tax which would
                           be payable by Executive pursuant to Section 4999 of
                           the Code, such accounting firm shall take into
                           consideration and apply all non-includible,
                           excludable and exempt amounts of compensation in
                           accordance with Section 280G of the Code. The parties
                           shall cooperate fully by promptly providing such
                           accounting firm all information required to complete
                           such determinations. Such

                           determinations shall be set forth in a written
                           statement and analysis thereof issued by such
                           accounting firm which shall be promptly furnished
                           to and shall be binding upon the parties. In the
                           event Executive is subject to any audit with respect
                           to the amount of such excise taxes, Executive and
                           UnitedHealth Group will mutually cooperate in
                           contesting such audit; provided that UnitedHealth
                           Group will pay the cost of such contest and will
                           reimburse Executive on an after tax basis for any
                           additional excise taxes payable as a result of such
                           audit and for any income taxable to Executive
                           as a result of UnitedHealth Group paying the cost of
                           such audit and any additional excise taxes. In the
                           event any such audit results in a refund of excise
                           taxes paid, Executive will turn over the refund to
                           UnitedHealth Group less any income taxes incurred by
                           Executive in respect of the receipt of the refund.

         (f)  TERMINATION OF EMPLOYMENT BY EXECUTIVE UPON RETIREMENT. If
              Executive terminates employment under Section 3(b)(iii) without
              Good Reason prior to the end of the term of this Agreement, and at
              the time of termination the Board of Directors of UnitedHealth
              Group or its Compensation and Human Resources Committee determines
              that such termination by Executive constitutes a retirement in
              good standing, then upon the termination of Executive's
              employment:

                  (i)      Unless the Board of Directors of UnitedHealth Group
                           or its Compensation and Human Resources Committee
                           otherwise determine, all cash compensation payable to
                           Executive shall cease as of the date of termination.

                  (ii)     Unless the Board of Directors of UnitedHealth Group
                           or its Compensation and Human Resources Committee
                           otherwise determine, with consent of Executive to
                           continue vesting of the Supplemental Employee
                           Retirement Plan and to defer its payout, Executive
                           shall be entitled to begin receiving payments under
                           the Supplemental Employee Retirement Plan described
                           in Section 2(g) as of the date of retirement.

                  (iii)    Executive shall be entitled to continue participation
                           in the health care coverage as provided in Section
                           3(j) below and all other life insurance or other
                           employee benefit plans of UnitedHealth Group
                           established under Section 2(f) of this Agreement to
                           the extent permitted by applicable law and the terms
                           and conditions of those plans. UnitedHealth group
                           shall for a period of thirty-six months following the
                           effective date of the termination (A) continue to pay

                                       12

                           coverage on a self-funded basis for Executive and his
                           dependents with UnitedHealth Group and Executive
                           sharing the costs associated with such coverage as if
                           Executive were still actively employed by
                           UnitedHealth Group, and (B) maintain and pay the
                           premiums with respect to the additional insurance
                           policies provided for in Section 2(i). Executive
                           shall continue to receive health care coverage as
                           provided in Section 3(j) of this Agreement. If
                           Executive cannot be covered under any of UnitedHealth
                           Group's group plans or policies, UnitedHealth Group
                           shall reimburse Executive for his full cost of
                           obtaining comparable alternative group or individual
                           coverage elsewhere, less any contribution that
                           Executive would have been required to make under
                           UnitedHealth Group's group plans or policies.
                           Executive shall receive any benefits payable under
                           Section 2(f) of this Agreement within sixty days of
                           such termination.

                  (iv)     Any vesting requirements or other conditions that an
                           employee or participant complete a longer period of
                           service or employment as shall otherwise theretofore
                           pertain to any of Executive's rights or benefits
                           under all outstanding options (excluding the Special
                           Option granted pursuant to Section 2(c) unless at the
                           time of retirement the Board of Directors of
                           UnitedHealth Group or its Compensation and Human
                           Resources Committee determines it is appropriate in
                           its discretion to vest all or a portion of the
                           unvested Special Option Shares and excluding any
                           option that specifies it will not vest in this
                           particular instance) or any bonus, incentive
                           compensation, deferred compensation, stock grant,
                           restricted stock, or similar plans, from time to time
                           implemented by UnitedHealth Group or its successor or
                           assign, shall automatically terminate and be of no
                           further force or effect. All such rights and benefits
                           shall continue to be deemed to be fully vested and,
                           as the case may be, subject to accrual, payment or
                           exercise in full, or transfer (unless expressly
                           non-transferable) without regard to such
                           restrictions. Stock options or grants awarded
                           Executive under any of UnitedHealth Group's stock
                           option or grant or similar stock plans to the extent
                           vested shall continue to be exercisable in accordance
                           with their terms for a period of up to seventy-two
                           months after termination of Executive's employment
                           subject to earlier termination upon expiration of the
                           option or grant in accordance with the terms of such
                           option or grant.

                  (v)      UnitedHealth Group shall provide Executive with
                           office, secretarial, and administrative support
                           reasonably customary for executives comparable to
                           Executive and shall provide Executive with use of

                           company aircraft for personal business to the same
                           extent Executive could so use such aircraft for
                           personal business prior to termination, all for a
                           period of thirty-six months following termination of
                           employment.

                  (vi)     All accrued and unpaid vacation to the date of
                           termination shall be paid to Executive.

                  (vii)    In the event the payments, the acceleration of
                           vesting of stock options or the provision of any
                           other benefits under this Agreement are "parachute
                           payments" within the meaning of, and the regulations,
                           rulings and procedures under, Sections 280G and 4999
                           of the Code or other related or successor sections
                           and provisions of the Code at any time applicable
                           thereto, and become subject to excise taxes under
                           Section 4999 of the Code, UnitedHealth Group will pay
                           Executive the amount of such excise taxes plus all
                           federal, state, and local taxes applicable to
                           UnitedHealth Group's payment of such excise taxes,
                           including any additional excise taxes due under
                           Section 4999 of the Code with respect to payments
                           made pursuant to this Section 3(d)(v). All
                           determinations required by this Section 3(f), upon
                           termination of Executive's employment and at
                           UnitedHealth Group's sole expense, shall forthwith be
                           made by UnitedHealth Group's regularly engaged
                           independent public accounting firm. In determining
                           the amount of excise tax which would be payable by
                           Executive pursuant to Section 4999 of the Code, such
                           accounting firm shall take into consideration and
                           apply all non-includible, excludable and exempt
                           amounts of compensation in accordance with Section
                           280G of the Code. The parties shall cooperate fully
                           by promptly providing such accounting firm all
                           information required to complete such determinations.
                           Such determinations shall be set forth in a written
                           statement and analysis thereof issued by such
                           accounting firm which shall be promptly furnished to
                           and shall be binding upon the parties. In the event
                           Executive is subject to any audit with respect to the
                           amount of such excise taxes, Executive and
                           UnitedHealth Group will mutually cooperate in
                           contesting such audit; provided that UnitedHealth
                           Group will pay the cost of such contest and will
                           reimburse Executive on an after tax basis for any
                           additional excise taxes payable as a result of such
                           audit and for any income taxable to Executive as a
                           result of UnitedHealth Group paying the cost of such
                           audit and any additional excise taxes. In the event
                           any such audit results in a refund of excise taxes
                           paid, Executive will turn over the refund to

                           UnitedHealth Group less any income taxes incurred by
                           Executive in respect of the receipt of the refund.

         (g)  TERMINATION OF EMPLOYMENT BY EXECUTIVE WITHOUT GOOD REASON. If
              Executive's employment with UnitedHealth Group is terminated by
              Executive under Section 3(b)(iii) without Good Reason prior to the
              end of the term of this Agreement then upon the termination of
              Executive's employment:

                  (i)      For a period of twenty-four months following the
                           effective date of the termination of employment,
                           Executive shall receive bi-weekly payments equal to
                           1/26 of Executive's annualized Cash Compensation. In
                           the event of any anticipated tax law change during
                           the payment period that would increase Executive's
                           taxes on such income, Executive may elect to take and
                           receive his remaining compensation under this Section
                           3(g)(i), discounted at an interest rate of 4% per
                           annum to the present value thereof, in a single lump
                           sum payable within thirty days after written request
                           therefor setting forth such anticipated tax law
                           change.

                  (ii)     The percentage of Cash Compensation paid pursuant to
                           the Supplemental Employee Retirement Plan
                           contemplated by Section 2(g) shall be determined as
                           of the date of termination. Payments under such plan
                           shall commence on the second anniversary of the
                           termination date.

                  (iii)    Executive's participation in the life insurance or
                           other employee benefit plans of UnitedHealth Group

                           those plans' terms and conditions. Executive shall
                           continue to receive health care coverage as provided
                           in Section 3(j) of this Agreement. Executive shall
                           receive any benefits payable under Section 2(f) of

                           termination.

                  (iv)     Any stock options or grants awarded Executive under

                           effective date of termination and, to the extent
                           vested, shall be exercisable for up to

         (h)  TERMINATION OF EMPLOYMENT IN THE EVENT OF DEATH. If Executive's
              employment with UnitedHealth Group is terminated under Section
              3(b)(iv) due to the death of Executive prior to the end of the
              term of this Agreement then upon the termination of Executive's
              employment:

                  (i)      For a period of twenty-four months following
                           Executive's death, Executive's beneficiaries shall
                           receive bi-weekly payments equal to 1/26 of
                           Executive's annualized Cash Compensation. In the
                           event of any anticipated tax law change during the
                           payment period that would increase Executive's taxes
                           on such income, Executive's beneficiaries may elect
                           to take and receive his remaining compensation under
                           this Section 3(h)(i), discounted at an interest rate
                           of 4% per annum to the present value thereof, in a
                           single lump sum payable within thirty days after
                           written request therefor setting forth such
                           anticipated tax law change.

                  (ii)     The Cash Compensation payable pursuant to the
                           Supplemental Employee Retirement Plan contemplated by
                           Section 2(f) shall commence.

                  (iii)    Executive's beneficiaries shall be entitled to
                           receive all proceeds from the life insurance provided
                           in accordance with this Agreement and any benefit
                           payable under Section 2(f) of this Agreement.
                           Executive's spouse and children shall continue to
                           receive health care coverage as provided in Section
                           3(j) of this Agreement.

                  (iv)     Any stock options or grants awarded Executive under
                           any of UnitedHealth Group's stock option or grant or
                           similar stock plans (excluding the Special Option
                           granted pursuant to Section 2(c) and any other option
                           that specifies it will not vest in this particular
                           instance) shall vest immediately upon Executive's
                           death and shall be exercisable by Executive's
                           beneficiaries for up to thirty-six-months following
                           the effective date of termination subject to earlier
                           termination of the option or grant in accordance with
                           the terms of such option or grant.

                  (v)      All accrued and unpaid vacation to the date of
                           termination shall be paid to Executive's estate.

         (i)  TERMINATION OF EMPLOYMENT IN THE EVENT OF PERMANENT DISABILITY. If
              Executive's employment with UnitedHealth Group is terminated under
              Section 3(b)(iv) due

                                       16

              to the Permanent Disability of Executive prior to the end of the
              term of this Agreement then:

                  (i)      For a period of twenty-four months, Executive shall
                           receive bi-weekly payments equal to 1/26 of
                           Executive's annualized Cash Compensation. In the
                           event of any anticipated tax law change during the
                           payment period that would increase Executive's taxes
                           on such income, Executive may elect to take and
                           receive his remaining compensation under this Section
                           3(i)(i), discounted at an interest rate of 4% per
                           annum to the present value thereof, in a single lump
                           sum payable within thirty days after written request
                           therefor setting forth such anticipated tax law
                           change.

                  (ii)     The Cash Compensation payable pursuant to the
                           Supplemental Employee Retirement Plan contemplated by
                           Section 2(f) shall be determined as of, and the
                           payments shall commence on, the second anniversary of
                           the termination date.

                  (iii)    Executive shall be entitled to receive health care
                           coverage in accordance with Section 3(j) of this
                           Agreement and disability benefits provided under any
                           other employee benefit plans or compensation policies
                           of UnitedHealth Group to executive officers of
                           similar rank in accordance with applicable law and
                           those plans' terms and conditions. Executive shall
                           receive any benefits payable under Section 2(f) of
                           this Agreement within sixty days of such termination.

                  (iv)     Any stock options or grants awarded Executive under
                           any of UnitedHealth Group's stock option or grant or
                           similar stock plans (excluding the special option
                           granted pursuant to Section 2(c) and any other option
                           that specifies it will not vest in this particular
                           instance) shall vest immediately and shall be
                           exercisable for up to thirty-six-months following the
                           effective date of termination subject to earlier
                           termination of such option or grant in accordance
                           with the terms and conditions of such option or
                           grant.

                  (v)      All accrued and unpaid vacation to the date of
                           termination shall be paid to Executive.

         (j)  HEALTH CARE CONTINUATION COVERAGE. Notwithstanding any other
              provision of this Agreement to the contrary, if Executive is
              terminated other than for Cause pursuant to Section 3(b)(v),
              UnitedHealth Group shall continue to provide, at no cost to
              Executive, health care coverage for Executive and his wife for the
              remainder of their lives and for his children until they attain
              age 25,

                                       17
<PAGE>

              substantially as in effect on the date of termination. If
              Executive, his wife, or his children cannot be covered under any
              of UnitedHealth Group's group plans or policies, UnitedHealth
              Group shall reimburse Executive for his full cost of obtaining
              comparable alternative group or individual coverage elsewhere,
              less any contribution that Executive would have been required to
              make under UnitedHealth Group's group health plans or policies.

4.       PROPERTY RIGHTS, CONFIDENTIALITY, NON-SOLICIT AND NON-COMPETE
         PROVISIONS.

         (a) UNITEDHEALTH GROUP'S PROPERTY.

                  (i)      Executive shall promptly disclose to UnitedHealth
                           Group in writing all inventions, discoveries, and
                           works of authorship, whether or not patentable or
                           copyrightable, which are conceived, made, discovered,
                           written, or created by Executive alone or jointly
                           with another person, group or entity, whether during
                           the normal hours of employment at UnitedHealth Group
                           or on Executive's own time, during the term of this
                           Agreement. Executive assigns all rights to all such
                           inventions and works of authorship to UnitedHealth
                           Group. Executive shall give UnitedHealth Group any of
                           the assistance it reasonably requires in order for
                           UnitedHealth Group to perfect, protect and use its
                           rights to inventions and works of authorship.

                           This provision shall not apply to an invention,
                           discovery, or work of authorship for which no
                           equipment, supplies, facility, or trade secret
                           information of UnitedHealth Group was used and which
                           was developed entirely on the Executive's own time
                           and which does not relate to the business of
                           UnitedHealth Group, to UnitedHealth Group's
                           anticipated research or development, or does not
                           result from any work performed by Executive for
                           UnitedHealth Group.

                  (ii)     Executive shall not remove any records, documents, or
                           any other tangible items (excluding Executive's
                           personal property) from the premises of UnitedHealth
                           Group in either original or duplicate form, except as
                           is needed in the ordinary course of conducting
                           business for UnitedHealth Group.

                  (iii)    Executive shall immediately deliver to UnitedHealth
                           Group, upon termination of employment with
                           UnitedHealth Group, or at any other time upon
                           UnitedHealth Group's request, any property, records,
                           documents, and other tangible items (excluding
                           Executive's personal property) in Executive's
                           possession or control, including data incorporated in
                           word processing, computer, and other data storage

                           as defined below.

         (b)  CONFIDENTIAL INFORMATION. During the course of his employment

              organization, strategies, business, and operations and
              UnitedHealth Group's past, current, or potential customers,
              providers, and suppliers. UnitedHealth Group considers such
              expertise, knowledge, and information to be valuable,
              confidential, and proprietary. For purposes of this Agreement,
              "Confidential Information" shall mean non-public information
              concerning the financial data, business strategies, product
              development (and proprietary product data), marketing plans, past,
              current, or potential customers, providers, and suppliers, and
              other proprietary information concerning UnitedHealth Group.
              During this Agreement and at all times thereafter, Executive shall
              not use such Confidential Information or disclose it to other
              persons or entities except as is necessary for the performance of
              Executive's duties for UnitedHealth Group or as has been expressly
              permitted in writing by UnitedHealth Group. Provided, however,
              that the foregoing covenant shall not apply to any information
              possessed by Executive prior to his employment by UnitedHealth
              Group, or to any information which is in or has entered the public
              domain or has been disclosed within any industry segment in which
              UnitedHealth Group or any subsidiary or affiliated company of
              UnitedHealth Group operates by or pursuant to the authority of
              UnitedHealth Group or any subsidiary or affiliated company of
              UnitedHealth Group.

         (c)  NON-SOLICITATION. During (i) the term of this Agreement, (ii) any
              period for which Executive is receiving payments under Sections
              3(d), 3(e), 3(f), or 3(g) of this Agreement, notwithstanding any
              lump-sum payment that Executive might receive under any such
              Section, (iii) any period following the termination of this
              Agreement in which Executive remains employed by UnitedHealth
              Group, and (iv) for a period of one year after the last day of the
              latest of any period described in (i), (ii) or (iii), Executive
              shall not directly or indirectly attempt to hire away any
              then-current employee of UnitedHealth Group or a subsidiary of
              UnitedHealth Group or to persuade any such employee to leave
              employment with UnitedHealth Group.

         (d)  NON-COMPETITION.

                  (i)      During the term of this Agreement and ending one year
                           after the later of (A) any period for which Executive
                           is receiving payments under Section 3(d), 3(e), 3(f),

                           under any such Section or (B) the last day in which
                           Executive remains employed by UnitedHealth Group
                           following termination of this Agreement (the
                           "Restriction Period"), Executive shall not directly
                           or indirectly solicit, divert, or take away from
                           UnitedHealth Group, or attempt to solicit, divert, or
                           take away from UnitedHealth Group, the business of
                           any person, partnership, company, or corporation with

                           affiliated company thereof in which UnitedHealth
                           Group has a more than 20% equity interest (the
                           "UnitedHealth Group Companies"), has established a
                           business or customer relationship; PROVIDED, HOWEVER,
                           that this Section 4(d)(i) shall apply only to the
                           business(es) in which UnitedHealth Group or any of
                           the UnitedHealth Group Companies were engaged prior
                           to or planned to be engaged in within six months
                           after the termination of this Agreement.

                  (ii)     During the Restriction Period, without UnitedHealth
                           Group's prior written consent, Executive shall not
                           engage or participate, either individually or as an
                           employee, consultant or principal, partner, agent,
                           trustee, officer or director of a corporation,
                           partnership, or other business entity, in any
                           business in which UnitedHealth Group or any of the
                           UnitedHealth Group Companies is engaged; PROVIDED,
                           HOWEVER, that this Section 4(d)(ii) shall apply only
                           to businesses whose primary business is in
                           competition with a material business of UnitedHealth
                           Group as of the date of termination of this
                           Agreement.

                  (iii)    Except as otherwise set forth below in Section
                           4(d)(iv), Executive's obligations under this Section
                           4(d) shall remain in effect only so long as
                           UnitedHealth Group continues to make the payments and
                           provide the benefits specified in Section 3(d), 3(e),
                           3(f), or 3(g) notwithstanding any lump sum payment
                           that Executive might receive under any such Section
                           (though UnitedHealth Group shall have no option to
                           discontinue such payments on its own).

                  (iv)     The provisions of this Section 4(d) shall terminate
                           one year after the date of termination of this
                           Agreement if Executive (A) elects not to receive any
                           further payments and benefits specified in Section
                           3(d), 3(e), 3(f), or 3(g), (B) pays to UnitedHealth

                           Executive upon the exercise of UnitedHealth Group
                           stock options (with profits equaling the spread
                           between the exercise price and the fair market value
                           at the close of business on the respective date of
                           exercise) that are accelerated pursuant to any such
                           Section, but only to the extent such options would
                           not otherwise have vested prior to exercise had

                           to any such Section which represents the period of
                           time for which this Section shall no longer remain in
                           effect.

5.       MISCELLANEOUS.

         (a) DEFINITIONS.  For purposes of this Agreement:

                  (i)      "Cash Compensation" means the sum of Executive's base
                           annual compensation together with Executive's
                           incentive compensation as hereinafter determined. In
                           determining base annual compensation, the greater of
                           $1,600,000 or the Executive's highest annualized base
                           salary shall be used. Executive's incentive
                           compensation shall equal the average incentive
                           compensation actually earned by Executive for the two
                           years preceding the date of determination for which
                           an incentive determination has been made.
                           Notwithstanding the foregoing, if Executive's
                           severance compensation is paid pursuant to Sections
                           3(e) or 3(f), then Executive's incentive compensation
                           will equal the greater of the amount determined in
                           accordance with this paragraph or an amount Executive
                           would have been paid at Executive's then target
                           level. In any event, incentive compensation shall
                           include the cash equivalent value at the time earned
                           of any incentive compensation earned and paid or
                           payable in Company Common Stock or other form of
                           consideration. The Special Bonus paid pursuant to
                           Section 2(e) shall be treated as if it were incentive
                           compensation received equally for 1997 and 1998.

                  (ii)     "Cause" means (A) the willful and continued failure
                           by Executive substantially to perform his duties
                           hereunder (other than any such failure resulting from
                           his disability or from termination by Executive for
                           Good Reason), after a written demand for substantial
                           performance is delivered to Executive that
                           specifically identifies the manner in which Executive
                           has not remedied such failure within a reasonable
                           time after receipt of such written notice; (B) a
                           violation of United's Code of Conduct that is
                           materially detrimental to UnitedHealth Group and that
                           Executive has not remedied within a reasonable time
                           after receipt of a written notice from UnitedHealth
                           Group that specifically identifies such violation;
                           (C) the conviction of Executive of a felony; or (D)
                           any other willful and material breach of

                                       21

                           this Agreement by Executive that Executive has not
                           remedied within a reasonable time after receipt of a
                           written notice from UnitedHealth Group that
                           specifically identifies such breach. For purposes of
                           this paragraph, no act, or failure to act, on
                           Executive's part will be deemed "willful" unless
                           done, or omitted to be done, by Executive not in good
                           faith and without reasonable belief that his action
                           or omission was in the best interest of UnitedHealth
                           Group.

                  (iii)    "Change in Control" means (A) the acquisition by an
                           individual, entity or group (within the meaning of
                           Section 13(d)(3) or 14(d)(2) of the Securities
                           Exchange Act of 1934, as amended (the "Exchange
                           Act")) of beneficial ownership (within the meaning of
                           Rule 13d-3 promulgated under the Exchange Act) of 50%
                           or more of the then outstanding shares of common
                           stock of UnitedHealth Group (the "Outstanding Common
                           Stock"); (B) individuals who, as of the date hereof,
                           constitute UnitedHealth Group's Board of Directors
                           (the "Incumbent Board") cease for any reason to
                           constitute at least a majority of the UnitedHealth
                           Group Board of Directors, provided, however, that any
                           individual becoming a director subsequent to the date
                           hereof whose election, or nomination for election by
                           UnitedHealth Group's shareholders, was approved by a
                           vote of at least a majority of the directors then
                           comprising the Incumbent Board shall be considered as
                           though such individual were a member of the Incumbent
                           Board, but excluding, for this purpose, any such
                           individual whose initial assumption of office occurs
                           as a result of either an actual or threatened
                           election contest (as such terms are used in Rule
                           14a-11 of Regulation 14A promulgated under the
                           Exchange Act) or other actual or threatened
                           solicitation of proxies or consents; (C) the approval
                           by the stockholders of UnitedHealth Group of a
                           reorganization, merger or consolidation, in each
                           case, with respect to which the beneficial owners of
                           the Outstanding Common Stock immediately prior to
                           such reorganization, merger or consolidation,
                           beneficially own, directly or indirectly, less than
                           two-thirds of the then outstanding shares of common
                           stock and the combined voting power of the then
                           outstanding voting securities entitled to vote
                           generally in the election of directors of the
                           corporation resulting from such reorganization,
                           merger or consolidation in substantially the same
                           proportions as their ownership, immediately prior to
                           such reorganization, merger or consolidation; or (D)
                           the approval by the stockholders of UnitedHealth
                           Group of (i) a complete liquidation or dissolution of
                           UnitedHealth Group or (ii) the sale or other
                           disposition of all or substantially all of the assets
                           of UnitedHealth Group.

                           forth in Section 4(b).

                  (iv)     "Permanent Disability" means Executive's inability by

                           results in a diminution in such position, authority,
                           duties or responsibilities, excluding for this
                           purpose an isolated, insubstantial and inadvertent

                           written notice from Executive to UnitedHealth Group
                           that specifically identifies such breach; or (G) any
                           failure by UnitedHealth Group to comply with and

                           Agreement. For purposes of the definition of "Good
                           Reason," any good faith determination of "Good
                           Reason" made by the Executive on or after the Change
                           of Control Date shall be conclusive.

                  (vi)     "Spouse" shall have the meaning set forth in Section
                           2(g).

         (b)  ASSIGNMENT. This Agreement shall be binding upon and shall inure
              to the benefit of the parties and their respective legal and
              personal representatives, heirs, successors, and assigns, but may
              not be assigned by either party (except by operation of law upon
              death or disability of Executive) without the prior written
              consent of the other party, provided that any assignment by
              UnitedHealth Group shall not relieve UnitedHealth Group of its
              obligations under this Agreement. UnitedHealth Group will require
              any successor (whether direct or indirect, by purchase, merger,
              consolidation or otherwise) to all or substantially all of its
              business and/or assets to assume expressly and agree to perform
              this Agreement in the same manner and to the same extent that
              UnitedHealth Group is required to perform under this Agreement if
              no such succession had taken place. As used in this Agreement,
              "UnitedHealth Group" shall mean each as hereinbefore defined and
              any successor to its business and/or assets as aforesaid which
              assumes and agrees to perform this Agreement by operation of law,
              or otherwise.

         (c)  NOTICES. All notices under this Agreement shall be in writing and
              shall be deemed to have been duly given if delivered by hand or
              mailed by registered or certified mail, return receipt requested,

                       Executive:

         (d)  ENTIRE AGREEMENT. This Agreement contains the entire understanding
              of the parties with respect to its subject matter and may be
              amended or modified only by a subsequent written amendment
              executed by the parties. This Agreement replaces and supersedes
              any and all prior employment or employment related agreements and
              understandings, including any letters or memos which may

                                       24
<PAGE>

              have been construed as agreements, between Executive and
              UnitedHealth Group or any of its subsidiaries and affiliated
              companies.

         (e)  CHOICE OF LAW. This Agreement shall be construed and interpreted
              under the applicable laws and decisions of the State of Minnesota.

         (f)  WAIVERS. No failure on the part of either party to exercise, and
              no delay in exercising, any right or remedy under this Agreement
              shall operate as a waiver; nor shall any single or partial
              exercise of any right or remedy preclude any other or further
              exercise of any right or remedy.

         (g)  ADEQUACY OF CONSIDERATION. Executive acknowledges and agrees that
              he has received, prior to or contemporaneously with the Effective
              Date, adequate consideration from UnitedHealth Group to enter into
              this Agreement.

         (h)  DISPUTE RESOLUTION AND REMEDIES. Any dispute arising between the
              parties relating to this Agreement or to Executive's employment by
              UnitedHealth Group shall be resolved by binding arbitration held
              in the City of Minneapolis pursuant to the Rules of the American
              Arbitration Association, except as hereinafter expressly modified.
              If the disputing and responding parties are unable to agree upon a
              resolution within forty-five business days after the responding
              party's receipt of written notice from the disputing party setting
              forth the nature of the dispute, within the following ten business
              days the disputing and responding parties shall select a mutually
              acceptable single arbitrator to resolve the dispute or, if the
              parties fail or are unable to do so, each shall within the
              following ten business days select a single arbitrator, and the
              two so selected shall select a third arbitrator within the
              following ten business days. Such single arbitrator or, as the
              case may be, panel of three arbitrators acting by majority
              decision, shall resolve the dispute within sixty days after the
              date such arbitrator, or the last of them so selected, is
              selected, or as soon thereafter as practicable. If either party
              refuses or fails to select an arbitrator within the time therefor,
              the other party may do so on such refusing or failing party's
              behalf. The arbitrators shall have no power to award any punitive
              or exemplary damages or may construe or interpret but shall not
              ignore or vary the terms of this Agreement and shall be bound by
              controlling law. The parties acknowledge that Executive's failure
              to comply with the Confidentiality, Non-Solicit and Non-Compete
              provisions of this Agreement will cause immediate and irreparable
              injury to UnitedHealth Group and that therefore the arbitrators,
              or a court of competent jurisdiction if an arbitration panel
              cannot be immediately convened, will be empowered to provide
              injunctive relief, including temporary or preliminary relief, to
              restrain any such failure to comply. The party not prevailing in
              the proceeding shall bear the costs and expenses thereof,
              including without limitation, the reasonable attorneys' fees of
              the prevailing

                                       25
<PAGE>

              party. The arbitration award or other resolution may be entered
              as a judgment at the request of the prevailing party by any court
              of competent jurisdiction in Minnesota or elsewhere.

         (i)  SURVIVAL. The provisions of Sections 2(f), 2(i), 3(c)-3(j), 4 and
              5 shall survive any termination of this Agreement pursuant to
              Section 3(b).

THIS AGREEMENT CONTAINS A BINDING ARBITRATION PROVISION THAT MAY BE ENFORCED BY
THE PARTIES.

                              EMPLOYMENT AGREEMENT

         This Agreement, effective as of October 13, 1999 (the "Effective
Date"), is made by and between Stephen J. Hemsley ("Executive") and United
HealthCare Corporation ("UnitedHealth Group" or the "Company") for the purpose
of setting forth the terms and conditions of Executive's employment by
UnitedHealth Group and to protect UnitedHealth Group's knowledge, expertise,
customer and provider relationships, and the confidential information
UnitedHealth Group has developed about its customers, providers, products,
operations, and services. Unless the context otherwise requires, when used in
this Agreement all references to "UnitedHealth Group" include any entity
affiliated with UnitedHealth Group.

         1. EMPLOYMENT. UnitedHealth Group hereby employs Executive as the
President of UnitedHealth Group. Executive shall, during the term of his
employment hereunder and subject to the supervision and control of the Chief
Executive Officer of UnitedHealth Group, perform such duties, have such power,
and exercise such supervision and control with regard to the business of
UnitedHealth Group as are commonly associated with or appropriate to the office
of the President. Executive shall report to the Chief Executive Officer of
UnitedHealth Group. Executive accepts such employment on the terms and
conditions set forth in this Agreement and, except as specifically superseded by
this Agreement, subject to all of UnitedHealth Group's policies and procedures,
as changed from time-to-time, in regard to its employees generally. As of the
Effective Date, all other prior employment related agreements between Executive
and UnitedHealth Group shall terminate in their entirety and no longer be of any
force or effect, except for any outstanding stock options or restricted stock
grants which shall continue in accordance with their terms.

         2. COMPENSATION.

         (a) BASE SALARY. Executive shall initially be paid a base annual salary
in the amount of $750,000 payable bi-weekly in accordance with UnitedHealth
Group's then current payroll practices, less all applicable withholdings and
deductions. From time-to-time the Chief Executive Officer shall review
Executive's performance and shall consider increasing Executive's compensation.

         (b) ANNUAL STOCK OPTIONS. Executive shall, each calendar year beginning
with 1999, receive nonqualified stock option grants to purchase a minimum of
150,000 shares of UnitedHealth Group's Common Stock (the "Annual Options"). The
exercise price for each share of common stock underlying the Annual Options
shall be the fair market value of one share of UnitedHealth Group Common Stock
at the time of the grant and vesting of the Annual Options shall be

<PAGE>

in not more than four equal annual installments commencing the year after the
grant based on the achievement of performance goals as determined by the
Board of Directors or a committee thereof, provided that each Annual Option
shall be fully vested on the ninth anniversary of the date of grant and the
Annual Options shall be subject to certain adjustments customary for options
of this type and consistent with UnitedHealth Group's options then being
granted. Each Annual Option shall be in accordance with and subject to the
terms and conditions of the UnitedHealth Group Corporation Amended and
Restated 1991 Stock and Incentive Plan, or any substitute or similar
successor plan (the "Stock Plan"). Notwithstanding the foregoing provisions
of this Section 2(b), the Executive shall be eligible to receive additional
awards of options to purchase shares of UnitedHealth Group stock, as
determined by the Board of Directors or an authorized committee thereof, in
accordance with the normal practices of UnitedHealth Group.

         (c) SPECIAL STOCK OPTION GRANT. In addition to the Annual Options
contemplated by Section 2(b) Executive shall also receive an option (the
"Special Option") to purchase 500,000 shares of UnitedHealth Group Common Stock.
The Special Option shall be substantially in the form of Exhibit 2(c) and shall
be subject to the terms and conditions of the Stock Plan. The exercise price for
the Special Option shall be $40.125 per share, subject to adjustment as provided
in the Stock Plan. The Special Option will expire on the tenth anniversary of
its issuance. The Special Option will become exercisable on the ninth
anniversary of its issuance, subject to acceleration upon the occurrence of
certain performance events as specified in the Special Option.

         (d) BONUS AND STOCK PLANS. Executive shall be eligible to participate
in UnitedHealth Group's incentive bonus and other bonus plans and shall be
eligible to receive grants or awards pursuant to UnitedHealth Group's stock
option and other incentive plans, all in accordance with the terms and
conditions of those plans and on a basis consistent with that customarily
provided for senior officers at the highest level of UnitedHealth Group.
Executive shall be eligible for a target annual payment under UnitedHealth
Group's Management Leadership Results Plan or successor plan of at least 125
percent of his then-current base annual salary.

         (e) SPECIAL BONUS. In recognition of Executive's strategic
accomplishments over the past two years, Executive shall be entitled to receive
a special one-time bonus in the amount of $600,000 (the "Special Bonus"). The
Special Bonus shall be paid in cash or UnitedHealth Group Common Stock, as
Executive elects upon reasonable notice to the Company. If Executive elects to
be paid in Common Stock the shares shall be valued at their closing price on the
date of payment. The Special Bonus shall be paid on January 4, 2000, subject
only to Executive's continued employment as of such date.

                                       2

         (f) EMPLOYEE BENEFITS. Executive shall be eligible to participate in
UnitedHealth Group's other employee benefit plans, including without limitation,
any life, health, dental, short-term and long-term disability insurance coverage
and any retirement or savings plans, in accordance with the terms and conditions
of those plans and on a basis consistent with that customarily provided for
senior officers at the highest level of UnitedHealth Group. Executive shall also
receive other benefits consistent with his office and position, which benefits
shall include, without limitation, an expense allowance the amount of which
shall be determined by the Chief Executive Officer and acceptable to Executive,
to be used for security considerations, such as home and personal security, tax
planning and financial planning expenses.

         (g) SUPPLEMENTAL EMPLOYEE RETIREMENT PLAN. Prior to the end of 2000,
UnitedHealth Group shall use its best efforts to establish and provide Executive
a supplemental retirement benefit plan, the terms of which shall be reasonable
and customary for executives of a similar position in comparably sized companies
(the "Supplemental Retirement Plan").

         (h) VACATION AND ILLNESS. Executive shall be entitled to paid vacation
and sick leave benefits each year in accordance with UnitedHealth Group's
then-current policies and on a basis consistent with that customarily provided
for senior officers at the highest level of UnitedHealth Group.

         (i) ADDITIONAL INSURANCE. In addition to any other insurance to which
Executive is entitled under Section 2(f), UnitedHealth Group shall provide and
pay for, and Executive (or a trust designated by Executive) shall own, a life
insurance policy on Executive in an amount equal to $2,000,000 (the "Life
Insurance"). UnitedHealth Group shall also make available for Executive to
purchase, at Executive's expense, additional life insurance on Executive in an
amount equal to $1,000,000 (the "Supplemental Life Insurance"). UnitedHealth
Group shall also provide for Executive an individual supplemental long term "own
occupation" disability insurance policy, which may be self-insured by
UnitedHealth Group, providing for monthly disability income payments to
Executive equal to 80% of his annual base salary on the Effective Date of this
Agreement, reduced by any monthly payments to Executive under other individual
or group disability income plans or policies provided and paid for by
UnitedHealth Group (the "Supplemental Long-Term Disability Benefit"). To the
extent that such Supplemental Long-Term Disability Benefit is insured,
UnitedHealth Group will increase the compensation of Executive by the amount of
the insurance premiums and Executive (or UnitedHealth Group on behalf of
Executive) will pay such premiums. The Life Insurance and Supplemental Long-Term
Disability Benefit policies called for by this subsection shall be maintained
throughout the term of this Agreement and during the period for which payments
are being made under Section 3(d) and Section 3(g). Executive shall be deemed
permanently disabled for purposes of such policy

                                       3
<PAGE>

if by reason of accident, illness, or injury he is unable to perform any of
the principal duties, responsibilities, or functions of his employment for a
period of 180 consecutive days (the "qualification period") or such shorter
period as provided in the policy for the Supplemental Long-Term Disability
Benefit. The monthly disability income payments to Executive shall begin
immediately after the running of the qualification period and shall continue
throughout the period of Executive's disability for the greater of five years
or until Executive reaches age sixty-five. UnitedHealth Group shall
compensate Executive on an after-tax basis for any additional income taxes
payable by Executive as a result of UnitedHealth Group's payment of premiums
with respect to the insurance policies described in this subsection.

         3. TERM AND TERMINATION.

                           a Change in Control (as defined below) or, in the
                           case of a termination for Good Reason under clause
                           (F) of the definition of Good Reason, within 30
                           months after the Change of Control, then for a period
                           of 12 months following the effective date of the
                           termination of employment, Executive shall receive
                           biweekly payments equal to 1/26 of two times the sum
                           of (A) Executive's annualized highest base salary,
                           plus (B) the average of the bonus or incentive
                           compensation paid or payable to Executive for the two
                           most recent calendar years (excluding any special or
                           one-time bonus or incentive compensation payments),
                           less all applicable withholdings or deductions.
                           Provided, however, in the event of any anticipated
                           tax law change during the payment period that would
                           increase Executive's taxes on

                                       5
<PAGE>

                           such income, Executive may elect to take and
                           receive his remaining compensation under this
                           Section 3(d)(i), discounted at a market rate to
                           the present value thereof, in a single lump sum
                           payable within thirty days after written request
                           therefor setting forth such anticipated tax law
                           change.

                  (ii)     If such termination occurs within one year of a

                           of a termination for Good Reason under clause (F) of
                           the definition of Good Reason, within 30 months after
                           a Change in Control, then for a period of 12 months
                           following the effective date of the termination of
                           employment, Executive shall receive biweekly payments
                           equal to 1/26 of three times the sum of (A)
                           Executive's annualized highest base salary plus (B)
                           the greater of (1) the annual bonus that would be
                           payable to Executive under any incentive compensation
                           plans in which Executive then participates at
                           Executive's then-current target level, or (2) the
                           average of the bonus or incentive compensation paid
                           or payable to Executive for the two most recent
                           calendar years (excluding any special or one-time
                           bonus or incentive compensation payments), less all
                           applicable withholdings or deductions. Provided,
                           however, in the event of any anticipated tax law
                           change during the payment period that would increase
                           Executive's taxes on such income, Executive may elect
                           to take and receive his remaining compensation under
                           this Section 3(d)(ii), discounted at a market rate to
                           the present value thereof, in a single lump sum
                           payable within thirty days after written request
                           therefor setting forth such anticipated tax law
                           change.

                  (iii)    If such termination does not occur within one year of
                           a Change in Control or, in the case of a termination
                           for Good Reason under clause (F) of the definition of
                           Good Reason, within 30 months after a Change in
                           Control, then at the time of termination the Board of
                           Directors, or duly authorized committee, of the
                           Company shall give consideration to vesting otherwise
                           unvested options held by Executive and shall also
                           give consideration to the period of time following
                           termination during which Executive may exercise
                           options held by Executive. If such termination occurs
                           within one year of a Change in Control, or, in the
                           case of a termination for Good Reason under clause
                           (F) of the definition of Good Reason, within 30
                           months after a Change in Control, all options not
                           otherwise vested, including the Special Option issued
                           pursuant to Section 2(c), shall vest upon the change
                           in Control and shall remain exercisable for a period
                           of three years following termination.

                  (iv)     Executive shall be entitled to continue participation
                           in the health care coverage as provided in Section

                           applicable law and those plans' terms and
                           conditions. If Executive cannot be covered under
                           any of UnitedHealth Group's group plans or
                           policies, UnitedHealth Group shall reimburse

                           comparable alternative group or individual
                           coverage elsewhere, less any contribution that
                           Executive would have been required to make under
                           UnitedHealth Group's group plans or policies.
                           UnitedHealth Group shall compensate Executive on
                           an after-tax basis for any additional income taxes
                           payable by Executive as a result of UnitedHealth
                           Group's payment of premiums with respect to the
                           insurance policies described in this subsection.
                           Executive shall receive any benefits payable under
                           Section 2(f) of this Agreement, as well as the
                           supplemental retirement benefit payable under
                           Section 2(g), within sixty days of such
                           termination.

                  (v)      UnitedHealth Group shall pay a reasonable amount for
                           outplacement and job search services for Executive by
                           a firm selected by the Executive and mutually
                           acceptable to UnitedHealth Group.

                  (vi)     All accrued and unpaid vacation to the date of
                           termination shall be paid to the Executive.

                  (vii)    In the event any of the payments, the acceleration of
                           vesting of stock options or the provision of any
                           other benefits under this Agreement or the Special
                           Option are "parachute payments" within the meaning
                           of, and the regulations, rulings and procedures
                           under, Sections 280G and 4999 of the Internal Revenue
                           Code of 1986, as the same from time to time may be
                           amended (the "Code"), or other related or successor
                           sections and provisions of the Code at any time
                           applicable thereto, and become subject to excise
                           taxes under Section 4999 of the Code, UnitedHealth
                           Group will pay Executive the amount of such excise
                           taxes plus all federal, state, and local taxes
                           applicable to UnitedHealth Group's payment of such
                           excise taxes, including any additional excise taxes
                           due under Section 4999 of the Code with respect to
                           payments made pursuant to this Section 3(d)(vii). All
                           determinations required by this Section 3(d), upon
                           termination of Executive's employment and at
                           UnitedHealth Group's sole expense, shall forthwith be
                           made by UnitedHealth Group's regularly engaged
                           independent public accounting firm. In determining
                           the amount of excise tax which would be payable by
                           the Executive pursuant to Section 4999 of the Code,
                           such accounting firm shall take into consideration
                           and apply all non-includible, excludable and exempt
                           amounts of compensation in accordance with Section
                           280G of the Code. The parties shall cooperate fully
                           by promptly providing such accounting firm all
                           information required to

                                       7
<PAGE>

                           complete such determinations. Such determinations
                           shall be set forth in a written statement and
                           analysis thereof issued by such accounting firm
                           which shall be promptly furnished to and shall be
                           binding upon the parties. In the event Executive
                           is subject to any audit with respect to the amount
                           of such excise taxes, Executive and UnitedHealth
                           Group will mutually cooperate in contesting such
                           audit; provided that UnitedHealth Group will pay
                           the cost of such contest and will reimburse
                           Executive on an after tax basis for any additional
                           excise taxes payable as a result of such audit and
                           for any income taxable to Executive as a result of
                           UnitedHealth Group paying the cost of such audit
                           and any additional excise taxes. In the event any
                           such audit results in a refund, Executive will
                           turn over the refund to UnitedHealth Group less
                           any income taxes incurred by Executive in respect
                           of the receipt of the refund.

         (e) TERMINATION OF EMPLOYMENT BY EXECUTIVE WITHOUT GOOD REASON. If
Executive's employment with UnitedHealth Group is terminated by Executive under
Section 3(b)(iii) without Good Reason then upon termination of Executive's
employment:

                  (i) All cash compensation payable to Executive shall cease.

                  (ii) Executive shall be entitled to continue participation in

         benefit plans of UnitedHealth Group, including, without limitation, the
         Supplemental Retirement Plan, Life Insurance, and the Supplemental
         Long-Term Disability Benefit, shall terminate in accordance with
         applicable law and those plans' terms and conditions. Executive shall
         receive any benefits payable under Section 2(f) of this Agreement, as
         well as the benefit under the Supplemental Retirement Plan, within 60
         days of such termination.

                  (iii) All accrued and unpaid vacation to the date of
         termination shall be paid to the Executive.

         (f) TERMINATION OF EMPLOYMENT IN THE EVENT OF DEATH. If Executive's
employment with UnitedHealth Group is terminated under Section 3(b)(iv) due to
the death of Executive then upon termination of Executive's employment:

                  (i) For a period of twelve months from the date of Executive's
         death Executive's beneficiaries shall receive (A) biweekly payments
         equal to 1/26 of Executive's annualized highest base salary as of the
         date of Executive's employment termination, plus (B) the average of the
         bonus or incentive compensation paid or payable to Executive for the
         two most recent calendar years (excluding any special or one-time bonus
         or incentive

                                       8

         compensation payments), less all applicable withholdings or
         deductions. Provided, however, in the event of any anticipated tax
         law change during the payment period that would increase Executive's
         taxes on such income, Executive's beneficiaries may elect to take and
         receive his remaining compensation under this Section 3(f)(i),
         discounted at a market rate to the present value thereof, in a single
         lump sum payable within thirty days after written request therefor
         setting forth such anticipated tax law change.

                  (ii) Executive's beneficiaries shall be entitled to receive
         all proceeds from the Life Insurance and Supplemental Life Insurance,
         if any, provided in accordance with this Agreement and any benefit
         payable under Section 2(f) of this Agreement, as well as the benefits
         under the Supplemental Retirement Plan. Executive's spouse and
         dependent children under age 25 shall continue to receive health care
         coverage as provided in Section 3(i) of this Agreement.

                  (iii) Any stock options or grants awarded Executive under any
         of UnitedHealth Group's stock option or grant or similar stock plans,
         other than the Special Option issued pursuant to Section 2(c), shall
         vest immediately upon Executive's death and shall be exercisable by
         Executive's beneficiaries during a period of three years following the
         termination.

                  (iv) All accrued and unpaid vacation to the date of
         termination shall be paid to the Executive's estate.

         (g) TERMINATION OF EMPLOYMENT IN THE EVENT OF DISABILITY. If
Executive's employment with UnitedHealth Group is terminated under Section
3(b)(iv) due to the permanent disability of Executive then upon termination of
Executive's employment:

                  (i) For a period of twelve months from the effective date of
         Executive's disability Executive shall receive (A) biweekly payments
         equal to 1/26 of Executive's annualized highest base salary as of the
         date of Executive's employment termination, plus (B) the average of the
         bonus or incentive compensation paid or payable to Executive for the
         two most recent calendar years (excluding any special or one-time bonus
         or incentive compensation payments), less all applicable withholdings
         or deductions. Provided, however, in the event of any anticipated tax
         law change during the payment period that would increase Executive's
         taxes on such income, Executive may elect to take and receive his
         remaining compensation under this Section 3(g)(i), discounted at a
         market rate to the present value thereof, in a single lump sum payable
         within thirty days after written request therefor setting forth such
         anticipated tax law change.

                  (ii) Executive, his spouse and children under 25 shall
         continue to receive health care coverage in accordance with Section
         3(i) of this Agreement. Executive shall receive the Supplemental
         Long-Term Disability Disability Benefit under Section 2(i) and any

         compensation policies of UnitedHealth Group to executive officers of
         similar rank in accordance with applicable law and those plans' terms
         and conditions. Executive shall receive any benefits payable under
         Section 2(f) of this Agreement and the benefit under the Supplemental
         Retirement Plan within sixty (60) days of such termination.

                  (iii) Any stock options or grants awarded Executive under any

         (h) DEFINITIONS. For purposes of this Agreement:

                  (i) "Cause" means (A) the willful and continued failure by
         Executive substantially to perform his duties hereunder (other than any
         such failure resulting from his disability or from termination by
         Executive for Good Reason), after a written demand for substantial
         performance is delivered to Executive that specifically identifies the
         manner in which Executive has not substantially performed his duties,
         and Executive has not remedied such failure within a reasonable time
         after receipt of such written notice; (B) a violation of UnitedHealth
         Group's Code of Conduct that is materially detrimental to UnitedHealth
         Group and that Executive has not remedied within a reasonable time
         after receipt of a written notice from UnitedHealth Group that
         specifically identifies such violations; (C) the conviction of
         Executive of a felony; or (D) any other willful and material breach of
         this Agreement by Executive that Executive has not remedied within a
         reasonable time after receipt of a written notice from UnitedHealth
         Group that specifically identifies such breach. For purposes of this
         paragraph, no act, or failure to act, on Executive's part will be
         deemed "willful" unless done, or omitted to be done, by Executive not
         in good faith and without reasonable belief that his action or omission
         was in the best interest of UnitedHealth Group.

                  (ii) "Change in Control" means (A) the acquisition by an
         individual, entity or group (within the meaning of Section 13(d)(3) or

         Act")) of beneficial ownership (within the meaning of Rule 13d-3
         promulgated under the Exchange Act) of 50% or more of the then
         outstanding shares of common stock of UnitedHealth Group (the
         "Outstanding Common Stock"); (B) individuals who, as of the date
         hereof, constitute UnitedHealth Group's Board of Directors (the
         "Incumbent Board") cease for any reason to constitute at least a

         however, that any individual becoming a director subsequent to the
         date hereof whose election, or nomination for election by
         UnitedHealth Group's shareholders, was approved by a vote of at
         least a majority of the directors then comprising the Incumbent
         Board shall be considered as though such individual were a member of
         the Incumbent Board, but excluding, for this purpose, any such
         individual whose initial assumption of office occurs as a result of
         either an actual or threatened election contest (as such terms are
         used in Rule 14a-11 of Regulation 14A promulgated under the Exchange
         Act) or other actual or threatened solicitation of proxies or
         consents; (C) the approval by the stockholders of UnitedHealth Group
         of a reorganization, merger or consolidation, in each case, with
         respect to which the beneficial owners of the Outstanding Common
         Stock immediately prior to such reorganization, merger or
         consolidation, beneficially own, directly or indirectly, less than
         two-thirds of the then outstanding shares of common stock and the
         combined voting power of the then outstanding voting securities
         entitled to vote generally in the election of directors of the
         corporation resulting from such reorganization, merger or
         consolidation in substantially the same proportions as their
         ownership, immediately prior to such reorganization, merger or
         consolidation; or (D) the approval by the stockholders of
         UnitedHealth Group of (i) a complete liquidation or dissolution of
         UnitedHealth Group or (ii) the sale or other disposition of all or
         substantially all of the assets of UnitedHealth Group.

                  (iii) "Good Reason" means (A) the assignment to Executive of
         any duties inconsistent in any respect with Executive's position
         (including status, offices, titles and reporting relationships),
         authority, duties or responsibilities as contemplated by Section 1 or
         any other action by UnitedHealth Group which results in a diminution in
         such position, authority, duties or responsibilities, excluding for
         this purpose an isolated, insubstantial and inadvertent action not
         taken in bad faith and which is remedied by UnitedHealth Group promptly
         after receipt of notice thereof given by Executive; (B) the failure by
         UnitedHealth Group to elect Executive to the position of the President
         or any other action by UnitedHealth Group which results in the
         diminution of Executive's position, authority, duties, or
         responsibilities, excluding an isolated, insubstantial and inadvertent
         action not taken in bad faith and which is remedied by Group promptly
         after receipt of notice thereof given by Executive; (C) any failure of
         UnitedHealth Group

         to pay base salary or incentive compensation or to grant Annual
         Options in accordance with Section 2(a), (b) and (d) or any failure
         by UnitedHealth Group to maintain or provide the plans, programs,
         policies and practices, or benefits described in Section 4(f), (g),
         (h) and (i) on the most favorable basis such plans programs,
         policies and practices were maintained and benefits are provided to

         Minnesota or within twenty-five miles of such current location,
         except for travel reasonably required in the performance of the
         Executive's responsibilities; (E) any purported termination by
         UnitedHealth Group of Executive's employment otherwise than as
         expressly permitted by this Agreement; (F) the resignation or
         termination of William W. McGuire, M.D., as Chief Executive Officer
         of UnitedHealth Group for any reason, provided, however, that the
         initial occurrence of Good Reason by reason of Dr. McGuire's
         termination or resignation shall not exist for the purposes of this
         clause (F) until twelve months after the effective date of such
         resignation or termination by Dr. McGuire; (G) any other material
         breach of this Agreement by UnitedHealth Group that is not remedied
         within a reasonable time after written notice from Executive to
         UnitedHealth Group that specifically identifies such breach; or (H)
         any failure by UnitedHealth Group to comply with and satisfy Section
         5(a) of this Agreement. For purposes of the definition of "Good
         Reason," any good faith determination of "Good Reason" made by the
         Executive on or after the Change of Control Date shall be conclusive.

         (i) HEALTH CARE CONTINUATION COVERAGE. Notwithstanding any other
provision of this Agreement to the contrary, if Executive's employment is
terminated for any reason other than by UnitedHealth Group for Cause,
UnitedHealth Group shall continue to provide, at no cost to Executive, health
care coverage for Executive and his wife until each of them has reached age 65
and for his dependent children until they attain age 25, as in effect on the
date of termination. UnitedHealth Group's obligation so to provide health care
coverage shall cease at such time as Executive becomes eligible for health care
coverage from another employer. If Executive, his wife, or his dependent
children under the age of 25 cannot be covered under any of UnitedHealth Group's
group plans or policies, UnitedHealth Group shall reimburse Executive for his
full cost of obtaining comparable alternative group or individual coverage
elsewhere, less any contribution that Executive would have been required to make
under UnitedHealth Group's group health plans or policies. UnitedHealth Group

4.       PROPERTY RIGHTS, CONFIDENTIALITY, NON-SOLICIT AND NON-COMPETE
PROVISIONS.

         (a)      PROPERTY RIGHTS.

                  (i) Executive shall promptly disclose to UnitedHealth Group in
         writing all inventions, discoveries, and works of authorship, whether
         or not patentable or copyrightable, which are conceived, made,
         discovered, written, or created by Executive alone or jointly with
         another person, group, or entity, whether during the normal hours of
         employment at UnitedHealth Group or on Executive's own time, during the
         term of this Agreement. Executive assigns all rights to all such
         inventions and works of authorship to UnitedHealth Group. Executive
         shall give UnitedHealth Group any of the assistance it reasonably
         requires in order for UnitedHealth Group to perfect, protect and use
         its rights to inventions and works of authorship.

         This provision shall not apply to an invention, discovery, or work of
         authorship for which no equipment, supplies, facility, or trade secret
         information of UnitedHealth Group was used and which was developed
         entirely on the Executive's own time and which does not relate to the
         business of UnitedHealth Group, to UnitedHealth Group's anticipated
         research or development, or does not result from any work performed by
         Executive for UnitedHealth Group.

                  (ii) Executive shall not remove any records, documents, or any
         other tangible items (excluding Executive's personal property) from the
         premises of UnitedHealth Group in either original or duplicate form,
         except as is needed in the ordinary course of conducting business for
         UnitedHealth Group.

                  (iii) Executive shall immediately deliver to UnitedHealth
         Group, upon termination of employment with UnitedHealth Group, or at
         any other time upon UnitedHealth Group's request, any property,
         records, documents, and other tangible items (excluding Executive's
         personal property) in Executive's possession or control, including data
         incorporated in word processing, computer, and other data storage
         media, and all copies of such records, documents, and information,
         including all Confidential Information, as defined below.

         (b) CONFIDENTIAL INFORMATION. During the course of his employment
Executive will develop, become aware of, and accumulate expertise, knowledge,
and information regarding UnitedHealth Group's organization, strategies,
business, and operations and UnitedHealth Group's past, current, or potential
customers, providers, and suppliers. UnitedHealth Group considers such
expertise,

                                      13

<PAGE>

knowledge, and information to be valuable, confidential, and proprietary, and
it shall be considered Confidential Information for purposes of this
Agreement. During this Agreement and at all times thereafter Executive shall
not use such Confidential Information or disclose it to other persons or
entities except as is necessary for the performance of Executive's duties for
UnitedHealth Group or as has been expressly permitted in writing by
UnitedHealth Group. Provided, however, that the foregoing covenant shall not
apply to any information possessed by Executive prior to his employment by
UnitedHealth Group, or to any information which is in or has entered the
public domain or has been disclosed within any industry segment in which
UnitedHealth Group or any subsidiary or affiliated company of UnitedHealth
Group operates by or pursuant to the authority of UnitedHealth Group or any
subsidiary or affiliated company of UnitedHealth Group.

         (c) NON-SOLICITATION. During (i) the term of this Agreement, (ii) any
period for which Executive is entitled to receive payments under Section 3 of
this Agreement, notwithstanding any lump-sum payment that Executive might
receive under Section 3(d)(i) or (ii), (iii) any period following the
termination of this Agreement in which Executive remains employed by
UnitedHealth Group, and (iv) for a period of one year after the last day of the
latest of any period described in (i), (ii) or (iii), Executive shall not
directly or indirectly attempt to hire away any then-current employee of
UnitedHealth Group or a subsidiary of UnitedHealth Group or to persuade any such
employee to leave employment with UnitedHealth Group.

         (d) NON-COMPETITION.

                  (i) During (A) the term of this Agreement, (B) any period for
         which Executive is entitled to receive payments under Section 3 of this
         Agreement, notwithstanding any lump-sum payment that Executive might
         receive under Section 3(d)(i) or (ii), and (C) any period following
         termination of this Agreement in which Executive remains employed by
         UnitedHealth Group (the "Restriction Period"), Executive shall not
         directly or indirectly solicit, divert, or take away from UnitedHealth
         Group, or attempt to solicit, divert, or take away from UnitedHealth
         Group, the business of any person, partnership, company, or corporation
         with which UnitedHealth Group has established a business or customer
         relationship; PROVIDED, HOWEVER, that this Section 4(d)(i) shall apply
         only to the business(es) in which UnitedHealth Group was engaged prior
         to or planned to be engaged in within six months after the termination
         of this Agreement.

                  (ii) During the Restriction Period, without UnitedHealth
         Group's prior written consent, Executive shall not engage or
         participate, either individually or as an employee, consultant or
         principal, partner, agent, trustee, officer or director of a
         corporation, partnership, or other business

                                      14

<PAGE>

         entity, in any business in which UnitedHealth Group or any of the
         UnitedHealth Group Companies is engaged; PROVIDED, HOWEVER, that
         this Section 4(d)(ii) shall apply only to businesses whose primary
         business is in competition with a material business of UnitedHealth
         Group as of the date of termination of this Agreement.

                  (iii) Executive's obligations under this Section 4(d) shall
         remain in effect only so long as UnitedHealth Group continues to make
         the payments and provide the benefits specified in Section 3(d)
         notwithstanding any lump sum payment that Executive might receive under
         Section 3(d)(i) or (ii) (though UnitedHealth Group shall have no option
         to discontinue such payments on its own).

                  (iv) If Executive elects to terminate Executive's employment
         pursuant to Section 3(b)(iii), UnitedHealth Group may elect to have the
         provisions of this Section 4(d) be in effect for up to 12 months
         following the effective date of such resignation if during such period
         UnitedHealth Group makes the payments specified in Section 3(d)(i). To
         be effective UnitedHealth Group shall notify Executive of its intention
         to make payments hereunder within ten days following Executive's notice
         of resignation.

5.       MISCELLANEOUS.

         (a) ASSIGNMENT. This Agreement shall be binding upon and shall inure to
the benefit of the parties and their respective legal and personal
representatives, heirs, successors, and assigns, but may not be assigned by
either party (except by operation of law upon death or disability of Executive
and except that UnitedHealth Group may assign its obligations hereunder to a
wholly owned subsidiary provided that such assignment shall not relieve
UnitedHealth Group of its obligations under this Agreement) without the prior
written consent of the other party. UnitedHealth Group will require any
successor (whether direct or indirect, by purchase, merger, consolidation or
otherwise) to all or substantially all of its business and/or assets to assume
expressly and agree to perform this Agreement in the same manner and to the same
extent that UnitedHealth Group is required to perform under this Agreement if no
such succession had taken place. As used in this Agreement, "UnitedHealth Group"
shall mean each as hereinbefore defined and any successor to its business and/or
assets as aforesaid which assumes and agrees to perform this Agreement by
operation of law, or otherwise.

         (b) NOTICES. All notices under this Agreement shall be in writing and
shall be deemed to have been duly given if delivered by hand or mailed by
registered or certified mail, return receipt requested, postage prepaid, to the
party to receive the same at the address set forth below or at such other
address as may have been furnished by proper notice.

                                        9900 Bren Road East
                                        Minnetonka, MN 55343
                                        Attn:  General Counsel

                  Executive:

         (c) ENTIRE AGREEMENT. This Agreement contains the entire understanding
of the parties with respect to its subject matter and may be amended or modified
only by a subsequent written amendment executed by the parties. This Agreement
replaces and supersedes any and all prior employment or employment related
agreements and understandings, including any letters or memos which may have
been construed as agreements, between Executive and UnitedHealth Group or any of
its subsidiaries and affiliated companies.

         (d) CHOICE OF LAW. This Agreement shall be construed and interpreted
under the applicable laws and decisions of the State of Minnesota.

         (e) WAIVERS. No failure on the part of either party to exercise, and no
delay in exercising, any right or remedy under this Agreement shall operate as a
waiver; nor shall any single or partial exercise of any right or remedy preclude
any other or further exercise of any right or remedy.

         (f) ADEQUACY OF CONSIDERATION. Executive acknowledges and agrees that
he has received, prior to or contemporaneously with the Effective Date, adequate
consideration from UnitedHealth Group to enter into this Agreement.

         (g) DISPUTE RESOLUTION AND REMEDIES. Any dispute arising between the
parties relating to this Agreement or to Executive's employment by UnitedHealth
Group shall be resolved by binding arbitration held in the City of Minneapolis
pursuant to the Rules of the American Arbitration Association, except as
hereinafter expressly modified. If the disputing and responding parties are
unable to agree upon a resolution within forty-five business days after the
responding party's receipt of written notice from the disputing party setting
forth the nature of the dispute, within the following ten business days the
disputing and responding parties shall select a mutually acceptable single
arbitrator to resolve the dispute or, if the parties fail or are unable to do
so, each shall within the following ten business days select a single
arbitrator, and the two so selected shall select a third arbitrator within the
following ten business days. Such single arbitrator or, as the case may be,
panel of three arbitrators acting by majority decision, shall resolve the
dispute within sixty days after the date such arbitrator, or the last of them so
selected, is selected, or as soon thereafter as practicable. If either party
refuses or fails to select an arbitrator within the time therefor, the other
party may do so on such

                                      16

<PAGE>

refusing or failing party's behalf. The arbitrators shall have no power to
award any punitive or exemplary damages or may construe or interpret but
shall not ignore or vary the terms of this Agreement and shall be bound by
controlling law. The parties acknowledge that Executive's failure to comply
with the Confidentiality, Non-Solicit and Non-Compete provisions of this
Agreement will cause immediate and irreparable injury to UnitedHealth Group
and that therefore the arbitrators, or a court of competent jurisdiction if
an arbitration panel cannot be immediately convened, will be empowered to
provide injunctive relief, including temporary or preliminary relief, to
restrain any such failure to comply. The party not prevailing in the
proceeding shall bear the costs and expenses thereof, including without
limitation, the reasonable attorneys' fees of the prevailing party. The
arbitration award or other resolution may be entered as a judgment at the
request of the prevailing party by any court of competent jurisdiction in
Minnesota or elsewhere.

         (h) SURVIVAL. The provision of Sections 2(f), 2(g), 2(i), 3(c)-3(i), 4
and 5 shall survive any termination of this Agreement.

THIS AGREEMENT CONTAINS A BINDING ARBITRATION PROVISION THAT MAY BE ENFORCED BY
THE PARTIES.

         IN WITNESS WHEREOF, this Agreement has been signed by the parties
hereto on the date set forth below.
