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conditions set forth in this Agreement and, except as specifically superseded by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




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


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.

                           plus (B) the average of the bonus or incentive

                           Provided, however, in the event of any anticipated
                           tax law change during the payment period that would
                           increase Executive's taxes on


                                       5


                           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

                           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
                           3(i) below and in the other life insurance or other

                           Agreement, according to and if permitted by
                           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
                           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

                           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


                           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

         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

         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

         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

                  (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

         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.

         termination shall be paid to the Executive.

         (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

         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
         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.

                  (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


                                      11




         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
         Executive on the Effective Date; (D) UnitedHealth Group's requiring
         Executive to be based at any office or location other than its
         principal executive offices at its current location in Minnetonka,
         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
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.

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




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



         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.

         UnitedHealth Group:            300 Opus Center
                                        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



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.
