EMPLOYMENT AGREEMENT

    This Agreement is made effective this 20th day of May 1998 (the 
"Effective Date") by and between R. Channing Wheeler ("Executive") and United 
HealthCare Services, Inc. ("UHS"). When used in this Agreement, UHS includes 
any affiliated entity of UHS. This agreement is for the purpose of setting 
forth certain terms and conditions of Executive's employment by UHS and to 
protect UHS's knowledge, expertise, customer relationships and the 
confidential information UHS has developed about its customers, products, 
operations and services. As of the Effective Date, this Agreement supersedes 
any prior employment-related agreement or agreements between Executive and 
UHS or any subsidiary or affiliate of UHS.

1.  EMPLOYMENT AND DUTIES.

    A.  EMPLOYMENT.  UHS hereby directly or through its subsidiaries employs 
Executive. 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forth in this Agreement and, except as specifically superseded by this 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 UHS's policies and procedures in regard to its 
employees.

    B.  DUTIES.  Executive shall perform such duties as are commonly 
associated with the position of the chief executive officer of the Strategic 
Business Services Division of United HealthCare Corporation ("UHC") reporting 
to Stephen Hemsley or another member of the Office of the Chairman or other 
comparable senior executive level position plus such other executive level 
responsibilities as are reasonably assigned to Executive in connection with 
his UHC duties. Executive agrees to devote substantially all of his business 
time and energy to the performance of his duties in a diligent and proper 
manner.

2.  COMPENSATION.

    A.  BASE SALARY.  Executive shall initially be paid a base annual salary 
in the amount of $400,000 payable bi-weekly, less all applicable withholdings 
and deductions. Executive shall receive a periodic performance review from 
his supervisor and consideration for an increase of such base salary, 
provided however that during each year of this Agreement, and subject to 
Executive's performance, the Executive will be treated for increases in base 
salary in the same manner as other executives at Executive's level are 
considered and granted increases in their base salary.

    B.  BONUS AND STOCK PLANS.  Executive shall be eligible to participate in 
UHS's incentive compensation plans and its stock option and grant plans, in 
accordance with the terms and conditions of those plans and applicable laws 
and regulations. Without limiting the generality of the foregoing, Executive 
will be entitled to participate in the UHC Management Incentive Program with 
a target participation of 85% of Executive's base earnings, and Executive 
will also be entitled to participate in the UHC Long Term Incentive Plan, 
subject, in each instance, to the terms and conditions of those plans as



they may be changed in the future. Any stock options granted to Executive will 
provide that upon a UHC or UHS Change of Control (as defined in Section 3D3 
all options granted to Executive shall be deemed fully vested.

    C.  EMPLOYMENT BENEFITS.  The Executive shall be eligible to participate 
in UHS's other employee benefit plans, including without limitation, any 
life, health, dental, short-term and long-term disability insurance coverages 
and any retirement plans, in accordance with the terms and conditions of 
those plans and applicable laws and regulations. UHS will provide, at its 
expense, a car and driver to transport Executive from his residence to the 
UHS offices and back to the Executive's residence on a daily basis, including 
all expenses associated with such transportation, provided however, that the 
expense of this car service to UHS will not exceed $4,500/month. Executive 
shall be entitled to choose the car service to provide these transportation 
services. This car service shall not be treated as a taxable benefit to 
Executive. In the event that Executive is required to pay a tax related to 
this car service, UHS will reimburse the Executive for the amount of the tax. 
Additionally, UHS will provide the Executive with full reimbursement for 
reasonable transportation expenses reasonably related to the discharge of 
Executive's duties connected with his employment by UHS. All of Executive's 
air travel related to his duties hereunder shall be provided by UHS at 
Business Class or First Class Level.

    D.  VACATION; ILLNESS.  Executive shall be entitled to paid vacation and 
sick leave each year in accordance with UHS's then-current policies.

3.  TERM AND TERMINATION.

    A.  TERM.  Unless terminated as set forth in Section 3B, the term of this 
Agreement shall begin on the date of its execution (the "Effective Date") and 
shall continue for an initial term of three years. This contract shall be 
automatically renewed from year to year thereafter for successive one-year 
terms until such time as an election not to renew is made pursuant to Section 
3B.

    B.  TERMINATION OF AGREEMENT AND/OR EMPLOYMENT.

        1.  This Agreement may be terminated at any time by the mutual 
    written agreement of the parties.

        2.  UHS may terminate Executive's employment, terminate this 
    Agreement, or elect not to renew this Agreement for a succeeding one-year 
    term, by giving written notice of termination or nonrenewal which is 
    received by Executive at least 60 days before the effective date of 
    termination or nonrenewal of employment or of this Agreement, as the case 
    may be. A Change in Employment as defined in 3D2 may, upon election by 
    Executive, be deemed to be a Termination of Executive's Employment under 
    this section 3B2.

        3.  Executive may terminate his employment, or elect not to renew this
    Agreement for a succeeding one-year term, by giving written notice of

                                       2




     termination or nonrenewal which is received by UHS at least 60 days 
     before the effective date of termination or nonrenewal of employment or 
     of this Agreement, as the case may be.

         4.  This Agreement shall automatically terminate on the effective 
     date of the termination of Executive's employment or on the date of 
     Executive's death, retirement or permanent and total disability which 
     renders Executive incapable of performing Executive's duties. The 
     Executive's permanent and total disability shall be determined in 
     accordance with the definitions of permanent and total disability as 
     contained in any disability insurance policy applicable to Executive and 
     provided by UHS for the benefit of Executive pursuant to Executive's 
     employment by UHS.

No other provisions of this Agreement withstanding, the termination of this 
Agreement shall not terminate any of UHS's obligations to Executive which by 
their terms would normally be performed after termination, including but not 
limited to UHS's duties under Sections 2B and 3C.

     C.  SEVERANCE EVENTS AND COMPENSATION.  In the event (i) Executive's 
employment with UHS is terminated or this Agreement is not renewed by UHS 
pursuant to Section 3B2 and without Cause, or (ii) Executive's employment 
with UHS is terminated or this Agreement is not renewed by UHS as result of 
Executive's disability pursuant to Section 3B4, or (iii) a Change in 
Employment occurs which Executive elects to treat as a Termination of 
Executive's Employment under Section 3B2 ((i), (ii), and (iii) are 
collectively referred to as the "Severance Events"), then:

         1.  For 12 months following the effective date of the termination of 
     Executive's employment ("Severance Period"). Executive shall receive 
     twenty six biweekly payments each equal to 1/26TH of (a) the highest 
     base salary that Executive earned at any time during the 90 day period 
     immediately prior to the effective date of termination, but in no event 
     less than a base salary of $400,000, less all applicable withholdings 
     or deductions required by law or Executive's elections under any 
     employee benefit plans which Executive continues to participate in under 
     Section 3C2, plus (b) all bonuses that would be payable to Executive 
     under the UHC Management Incentive Program at Executive's current target 
     level, but in no event less than a target level of 85% of base salary 
     ((a) and (b) are collectively referred to as the "Severance 
     Compensation"). Further, UHS management will in good faith and without 
     reservations with regard to establishing precedent, request approval 
     from the Compensation Committee for the payment of the Executive's 
     portion of the payments/benefits under the UHC Long Term Incentive Plan 
     (LTIP) prorated through the effective date of termination. The Executive 
     will not disclose to any other UHS employee this provision for potential 
     participation in the LTIP and if such participation is granted, 
     Executive will keep such LTIP participation confidential.

     For the purposes of calculating Executive's bonus pursuant to Section 
     3C1(b) Executive's severance level annual base salary will be multiplied 
     by the
                                       


                                       3

                                       
     Executive's then bonus target level, provided however that such bonus 
     target level shall not be less than 85%.

     By way of example, if the Executive's base salary for the purposes of 
     calculation of Severance Benefits was $400,000 per year then at the 
     minimum target level of 85% of base salary, the bonus to the Executive 
     would be $400,000 X 85% = $340,000. Executive would receive a gross 
     bonus payment as part of each biweekly Severance Compensation payment of 
     $340,000/26 = $13,076.92.

     Executive's biweekly payments shall be reduced on a net dollar for net 
     dollar basis based on the net amount of compensation which Executive 
     receives in that biweekly period as a result of employment or work as an 
     independent contractor providing consulting or executive services in the 
     Health Care industry. In the event that the Executive's employment with 
     UHS is terminated as a result of disability, injury, or illness and also 
     if during the Severance Period Executive receives disability insurance 
     compensation from a disability plan or policy provided through 
     Executive's employment with UHS, then Executive's biweekly payments 
     shall be similarly reduced on a net dollar for dollar basis based on the 
     net after tax amount of disability insurance payments which the 
     Executive receives for that biweekly period. Executive shall promptly 
     disclose to UHS any such compensation.

          2.  As of the effective date of termination of employment, 
     Executive shall cease to be eligible for all benefit plans maintained by 
     UHS, except as required by federal or state continuation of coverage 
     laws. If Executive elects continuation of coverage under one or more 
     benefit plans subject to such continuation requirements, UHS shall, for 
     the Severance Period, pay on behalf of Executive the same percentage of 
     premium or converge charges that UHS would have paid on behalf of 
     Executive for such benefit plan had Executive remained employed by UHS 
     with participation at the same benefit level.

          3.  During the Severance Period UHS shall pay to an outplacement 
     firm selected by UHS an amount deemed reasonable by UHS for outplacement 
     and job search services for Executive.

          4.  Any unvested stock options or grants awarded Executive under 
     any of UHS's stock option or grant plans shall continue to vest during 
     the Severance Period in accordance with those options' or grants' 
     pre-established or usual vesting schedule.

The payments and benefits to Executive under this Section 3C shall be the 
sole liability of UHS to Executive in the event of a Severance Event and 
shall replace and be in lieu of any payments or benefits which otherwise 
might be owed by UHS under any other severance plan or program and such 
payments and benefits may be conditioned by UHS upon receipt of a release of 
claims from Executive. Solely for purposes of stock options and grants, the 
date of termination of employment shall be the last day of the Severance 
Period.

D.   DEFINITIONS AND PROCEDURE.

     1.  For purposes of this Agreement "Cause" shall mean

         (a)  the failure or refusal of Executive to follow the reasonable 
     directions of UHS's Board of Directors or Executive's supervisor or to 
     perform any duties reasonably required by UHS, or

         (b)  a failure to adequately meet reasonable performance 
     expectations, or

         (c)  material violations of UHS's Code of Conduct, or

         (d)  the commission of any criminal act or act of fraud or dishonesty 
     by Executive in connection with Executive's employment by UHS.

     In the event that UHS elects to terminate Executive's employment under 
     subsections (a) or (b) of this Clause definition, UHS shall give the 
     Executive a written notice of intended termination and shall specify in 
     such notice the basis for Cause. Executive shall have 60 (sixty) days 
     after the receipt of such notice to cure such Cause to UHS's reasonable 
     satisfaction. If the Cause described in the notice is reasonably cured 
     prior to the end of the 60 day period, the notice of intention to 
     terminate employment shall be deemed withdrawn and Executive shall not 
     be terminated for Cause. If the grounds for the Cause is Executive's 
     failure under Section 3D1(a) or (b) and further if that failure is 
     primarily the result of Executive's illness or injury, then if Executive 
     returns to full time service within the sixty day cure period, such 
     return to full time duties will be deemed to have cured the Cause.

     2.  For purposes of this Agreement "Change in Employment" shall be 
         deemed to have occurred if

         (a)   (i)  there is material adverse or detrimental change in the 
     Executive's job description, scope of responsibilities, duties, or 
     reporting level, without Executive's prior consent, or

              (ii)  Executive's salary or benefits are reduced other than as 
         a general reduction of salaries and benefits by UHS, or

             (iii)  without terminating Executive's employment this 
         Agreement is terminated by UHS pursuant to Section 3B2, or

              (iv)  during the first four years immediately following the 
         Effective Date UHS seeks to move Executive's principal place of
                                       

                                       5


         performance of his duties to a place which requires a longer travel 
         time or is farther away from Executive's home in Westport, 
         Connecticut. It is understood that UHS reserves the right to relocate 
         portions of the business and that such relocation in and of itself 
         will not constitute a Change in Employment provided that Executive's 
         principal office is not relocated as a result, or

               (v)  in the event of a Change in Control as defined in 
         Section 3D3, or

              (vi)  in the event that UHS materially breaches any of its 
         obligations to Executive under this Agreement and such breach is 
         not reasonably cured by UHS within 30 days after receipt of written 
         notice from Executive,

     and

         (b)  if in each case under subsections (a) (i), (ii), (iii), (iv), 
     (v), and (vi) in the period beginning 60 days before the time the Change 
     in Employment occurs, Cause does not exist, or if Cause does exist UHS 
     has not given Executive written notice that Cause exists, or if UHS has 
     given Executive written notice that Cause exists, the Executive has 
     reasonably cured such Cause during the 60 (sixty) day notice period,

     then the Executive may elect to treat a Change in Employment as a 
     Termination of Executive's Employment by UHS and as a Severance Event.

     To do so Executive shall send written notice of such election to UHS 
     within 60 days after the date Executive receives notice from UHS or 
     otherwise is definitively informed of the events constituting the Change 
     in Employment. No Change in Employment shall be deemed to have occurred 
     if Executive fails to send the notice of election within the 60 day 
     period. Executive's failure to treat a particular Change in Employment 
     as a termination of employment shall not preclude Executive from 
     treating a subsequent Change in Employment as a termination of 
     employment. The effective date of a Change in Employment termination 
     shall be the date 30 days after UHS receives the written notice of 
     election.

     3.  For purposes of this Agreement "Change of Control" shall mean any of 
the following which occurs subsequent to the Effective Date:

         (a)  any person (as such term is defined under Section 13(d)(3) of 
     the Securities Exchange Act of 1934, as amended (the "Exchange Act")), 
     corporation, or other entity (other than UHS, UHC, or any employee 
     benefit plan sponsored by UHS, UHC, or any of their subsidiaries), is or 
     becomes the beneficial owner (as such term is defined in Rule 13d-3
                                       

                                       6




         under the Exchange Act) of securities of UHS or UHC representing 
         over 50% percent (50%) of the combined voting power of the 
         outstanding securities of UHS or UHC which ordinarily (and apart 
         from rights accruing under special circumstances) have the right to 
         vote in the election of directors (calculated as provided in 
         paragraph (d) of such Rule 13d-3 in the case of rights to acquire 
         UHS's or UHC's securities) (the "Securities"); or

                  (b) as a result of a tender offer, merger, sale of assets 
         or other major transaction, the persons who are directors of UHS or 
         UHC immediately prior to such transaction cease to constitute a 
         majority of the Board of Directors of UHS or UHC (or any successor 
         corporations) immediately after such transaction; or

                  (c) UHS or UHC are merged or consolidated with any other 
         person, firm, corporation or other entity and, as a result, the 
         shareholders of UHS or UHC, as determined immediately before such 
         transaction, own less than eighty percent (80%) of the outstanding 
         Securities of the surviving or resulting entity immediately after 
         such transaction; or

                  (d) a tender offer or exchange offer is made and 
         consummated for the ownership of fifty percent (50%) or more of the 
         outstanding Securities of UHS or UHC; or

                  (e) UHS or UHC transfer substantially all their assets to 
         another person, firm, corporation or other entity that is not a 
         wholly-owned subsidiary of UHC or UHC; or

                  (f) UHS or UHC enter into a management agreement with 
         another person, firm, corporation or other entity that is not a 
         wholly-owned subsidiary of UHS or UHC and such management agreement 
         extends hiring and firing authority over Executive to an individual 
         or organization other than UHS or UHC.

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

         A.   UHS'S PROPERTY.

              1.  Executive shall promptly disclose to UHS 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 UHS 
         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 UHS. Executive shall give UHS any assistance it 
         reasonably requires in order for UHS to perfect, protect, and use its 
         rights to inventions and works of authorship.
                                       

                                       7


              This provision shall not apply to an invention for which no 
         equipment, supplies, facility or trade secret information of UHS was 
         used and which was developed entirely on the Executive's own time and 
         which (1) does not relate to the business of UHS or to UHS's 
         anticipated research or development, or (2) does not result from any 
         work performed by the Executive for UHS.

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

              3.  Executive shall immediately deliver to UHS, upon termination 
         of employment with UHS, or at any other time upon UHS'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 UHS's organization, strategies, 
    business and operations and UHS's past, current or potential customers 
    and suppliers. UHS considers such expertise, 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 UHS 
    or as has been expressly permitted in writing by UHS.

         C.  NON-SOLICITATION.  During (i) the term of this Agreement, (ii) 
    any period for which Executive is receiving payments under Section 3C of 
    this Agreement, and (iii) any period following the termination or 
    expiration of this Agreement during which Executive remains employed by 
    UHS, Executive shall not (y) directly or indirectly attempt to hire away 
    any then-current employee of UHS or a subsidiary of UHS or to persuade 
    any such employee to leave employment with UHS, or (z) directly or 
    indirectly solicit, divert, or take away, or attempt to solicit, divert, 
    or take away, the business of any person, partnership, company or 
    corporation with whom UHS (including any subsidiary or affiliated company 
    in which UHS has a more than 20% equity interest) has established or is 
    actively seeking to establish a business or customer relationship.

         D.  NON-COMPETITION.  During (i) the term of this Agreement, (ii) any 
    period for which Executive is receiving payments under Section 3C of this 
    Agreement, and (iii) any period following the termination or expiration 
    of this Agreement during which Executive remains employed by UHS, 
    Executive shall not, without UHS's prior written consent, within the 
    United States of America, 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 UHS
                                       

                                       8



(including any subsidiary of affiliated company in which UHS has a more than 
20% equity interest) is engaged.

     In the event that Executive elects to terminate Executive's employment 
pursuant to Section 3B3. UHS may elect to have the provisions of this Section 
4D be in effect for up to twelve months following the effective date of such 
resignation if, during the period up to twelve months specified by UHS, UHS 
provides to the Executive all of the Severance Benefits described in Sections 
3C1 through 3C4.

     UHS must send written notice of such election within 10 days after it 
receives written notice of the termination of employment. Executive's biweekly 
payments shall be reduced by a net dollar for net dollar basis based on the 
net amount of compensation which Executive receives in that biweekly period 
as a result of employment or work as an independent contractor providing 
consulting or executive services in the Health Care industry. Executive shall 
promptly disclose to UHS any such compensation.

5.  MISCELLANEOUS.

    A. ASSIGNMENT. This Agreement shall be binding upon and shall insure to 
the benefit of the parties and their successors and assigns, but may not be 
assigned by either party without the prior written consent of the other 
party, except that UHS in its sole discretion may assign this Agreement to an 
entity controlled by UHS at the time of the assignment. If UHS subsequently 
loses or gives up control of the entity to which this Agreement is assigned, 
such entity shall become UHS for all purposes under this Agreement, beginning 
on the date on which UHS loses or gives up control of the entity. Any 
successor to UHS shall be deemed to be UHS for all purposes of this Agreement.

     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.

     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 

                                      9


understandings, including any letters or memos which may have been construed 
as agreements, between the Executive and UHS 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 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/she has received adequate consideration from UHS to enter into this 
Agreement.

     G. MEDIATION. In the event of any dispute between the parties concerning 
this Agreement, both parties agree to participate in good faith in nonbinding 
mediation of that dispute with each party to pay its own attorney's fees and 
costs and the parties to equally divide the costs of the mediator.

     H. DISPUTE RESOLUTION AND REMEDIES. Any dispute arising between the 
parties relating to this Agreement or to Executive's employment by UHS shall 
be resolved by binding arbitration pursuant to the Rules of the American 
Arbitration Association. In no event may the arbitration be initiated more 
than two years after the date one party first gave written notice of the 
dispute to the other party. The arbitrators shall not ignore or vary the 
terms of this Agreement and shall be bound by and apply controlling law, but 
may not in any case award any punitive or exemplary damages.

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 UHS 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.

     I. NO THIRD-PARTY BENEFICIARIES. This Agreement shall not confer or be 
deemed or construed to confer any rights or benefits upon any person other 
than the parties.

     J. ATTORNEY'S FEES. In the event that Executive prevails in any 
controversy, claim or dispute with UHS or UHC or any successor or assignee 
arising out of or relating to this agreement or breach thereof, Executive 
shall also recover reasonable attorney's fees and costs, including attorney's 
fees incurred on or after appeal to attorney's fees incurred after judgment 
in the collection process. Because of the differing financial positions of 
the parties, UHS and UHC shall not be entitled to recover attorney's fees 
from Executive in the event that UHS or UHC is the prevailing party in any 
dispute or action with Executive relating to this agreement.

                                      10
