EMPLOYMENT AGREEMENT
                                      
     This Agreement is made effective this 19th day of May, 1998 (the 
"Effective Date") by and between Arnold H. Kaplan ("Executive") and United 
HealthCare Services, Inc. ("UHS") (when used in this Agreement, UHS includes 
any affiliated entity of UHS) 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    set forth in this Agreement and, except as specifically superseded by 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 his positions as the Chief Financial Officer of United 
    HealthCare Corporation ("UHC") or such other senior executive level 
    responsibilities as are reasonably assigned to Executive by his 
    supervisor from time-to-time. As Chief Financial Officer, Executive will 
    report directly to UHC's Senior Executive Vice President, such 
    executive's successor, or another member of UHC's Office of the 
    Chairman, excluding, however, any Chief Administrative Officer that may 
    from time to time be appointed by UHC and serve as a member of the 
    Office of the Chairman. Executive agrees to devote substantially all of 
    his business time and energy to the performance of his duties in a 
    diligent and proper manner. UHS acknowledges that Executive shall 
    maintain his permanent residence in Emmaus, Pennsylvania.
    
2.  COMPENSATION.

    A.  BASE SALARY. Executive shall initially be paid a base annual salary 
    in the amount of $375,000 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.
    
    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, as long as Executive remains employed by UHS:
    
    1. Executive will be entitled to participate in the UHC Management 
    Incentive Program. Executive's minimum initial participation will be 75% 
    of Executive's base annual salary. For 1998, Executive's payment, before 
    applicable withholding and deductions, shall not be less than $141,000. 
    For 1999, Executive's payment, before applicable withholding and 
    deductions, shall not be less than the sum of $141,000 and half of the 
    product of the "factor" applied to Executive's functional unit and 
    Executive's then participation factor.
    
    2.  Executive will be entitled to participate in the UHC Long Term 
    Incentive Plan. Executive's participation shall include UHS' start up 
    cycle and first cycle on a time-calculated pro rata basis beginning 
    on the Effective Date.

    3. Executive will be entitled to participate in the UHC Stock Option 
    Plan from and after the Effective Date without any proration or other 
    limitation based on length of tenure. While not contractually binding, 
    UHC has advised Executive that currently executive comparable to 
    Executive annually receive options to purchase



    approximately 25,000 shares of UHC Common Stock. Pursuant to the UHC 
    Stock Option Plan, Executive will receive an initial option grant to 
    purchase 75,000 shares of UHC Common Stock at an exercise price of 
    $52.25, which option grant will vest equally over a four-year period on 
    the anniversary of Executive's employment. Options granted to Executive, 
    including the initial option grant described above, will fully vest upon 
    Executive's retirement or any other termination of this Agreement, other 
    than a termination for Cause as herein defined. Options granted to 
    Executive, once vested, shall remain exercisable for the remaining term 
    of the option, subject to any forfeiture or "clawback" provisions in any 
    option. Any stock options granted to Executive will provide that upon a 
    UHC change of control all options granted to Executive shall be deemed 
    fully vested.
    
    C.  INITIAL BONUS. As an additional incentive payment, UHS agrees to pay 
    Executive a one-time payment of $50,000, less all applicable withholding 
    and deductions provided that Executive commences employment no later 
    than July 1, 1998. This payment will be made approximately one month 
    following the date on which Executive commences active employment 
    hereunder.
    
    D.  MOVING ALLOWANCE. UHS will provide Executive with relocation benefits 
    equal to $75,000 in accordance with UHS policies previously provided to 
    Executive. In addition, for a period of six months following July 1, 
    1998, UHS will reimburse Executive for reasonable transition expenses 
    that Executive incurs. UHS will reimburse Executive the cost of any 
    federal and state income taxes payable with respect to the payments made 
    under this paragraph.
    
    E.  EMPLOYEE BENEFITS. The Executive shall be eligible to participate in 
    UHS's other employee benefit plan, 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. Without 
    limiting the generality of the foregoing. Executive will be entitled to 
    receive a monthly benefit payment of $1,200, a one-time payment of $750 
    for business related expenses, and annual financial planning benefits up 
    to $6,000, all in accordance with the terms and conditions of such plans 
    and programs.
    
    F.  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. The term of this Agreement shall begin on the Effective Date 
    and shall continue unless and until terminated as set forth in 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 or terminate this Agreement
        by giving written notice of termination which is received by Executive 
        at least 30 days before the effective date of termination of employment 
        or of this Agreement, as the case may be.
        
        3. Executive may terminate his employment by giving written notice of 
        termination of employment which is received by UHS at least 30 days 
        before the effective date of termination of employment.
        
        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

                                      2



    disability which renders Executive incapable of performing Executive's 
    duties. UHS has the sole discretion to determine whether Executive is 
    permanently or totally disabled with the meaning of this Section 3B4.
    
C.  SEVERANCE EVENTS AND COMPENSATION. In the event (i) Executive's 
employment with UHS is terminated by UHS pursuant to Section 3B2 and without 
Cause or (ii) a Change in Employment occurs which Executive elects to treat 
as a termination of Executive's employment under Section 3B2 ((i) and (ii) 
are collectively referred to as the "Severance Events"), then:

    1.  For the "Severance Period," as hereinafter defined, Executive shall 
    receive biweekly payments equal to the greater of (a)(i) the quotient of 
    $1,000,000 and 36 if the Severance Event occurs within 24 months of the 
    Effective Date or (ii) the quotient of $700,000 and 24 if the Severance 
    Event occurs more than 24 months after the Effective Date but within 36 
    months of the Effective Date and (b) and amount equal to 1/26 of (i) 
    Executive's annualized base salary at the effective date of termination, 
    plus (ii) one-half of the total of any bonus or incentive compensation 
    (but not including any special or one-time bonus or incentive 
    compensation payments) paid or payable to Executive for the two most 
    recent calendar years or other periods generally used by UHS to determine 
    such bonus or incentive compensation, or if Executive has been eligible 
    for such bonus or incentive compensation payments for less than two such 
    periods, the last such payment paid or payable to Executive (the amounts 
    paid pursuant to (a) or (b) are referred to as the "Severance 
    Compensation"). The Severance Compensation shall be reduced by any 
    compensation which Executive receives or reasonably could have received in 
    each biweekly period as a result of employment or work as an independent 
    contractor elsewhere. Executive shall promptly disclose to UHS any such 
    compensation. For purposes of this Agreement, the "Severance Period" 
    shall equal: 13 months if a Severance Event occurs within 24 months of 
    the Effective Date; 12 months if a Severance Event occurs more than 24 
    but within 36 months of the Effective Date; and such period of time as 
    is consistent with UHS' then prevailing severance policies for executive 
    officers comparable to the Executive if a Severance Event occurs more 
    than 36 months after the Effective Date. Any payments hereunder will be 
    reduced by 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. If a Severance Event occurs 
    more than 36 months after the Effective Date in connection with a change 
    of control of UHC Executive shall receive Severance Compensation equal to 
    the greater of $700,000 or such amount as is payable in accordance with 
    UHC's prevailing policies.

    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 an amount equal to UHS's employer 
    contribution for similarly situated active employees' coverages under 
    such benefit plans. During the Severance Period Executive's share of 
    coverage costs for such benefit plans shall be deducted automatically 
    through after-tax payroll deduction from the Severance Compensation.
    
    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. Executive shall be paid a portion of the Management Incentive Program 
    payments for the year in which termination of this Agreement occurs and 
    shall also be entitled to a position of the payments under the Long-Term 
    Incentive Plan. Payments shall be prorated based on the time at which 
    this Agreement terminates and shall be paid promptly following their 
    determination in accordance with the plan.

                                      3



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 owned 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.

D.  DEFINITION AND PROCEDURE.

    1.  For purposes of this Agreement, "Cause" shall mean (a) the 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 on material matters by UHS, (b) material violations of UHS's 
    Code of Conduct or (c) the commission of any criminal act or act of 
    fraud or dishonesty by Executive in connection with Executive's 
    employment by UHS. Prior to the termination of Executive's employment 
    under subsection (a) of this Cause definition. UHS shall provide 
    Executive with a 30 day notice specifying the basis for Cause. If the 
    Cause described in the notice is cured to UHS's reasonable satisfaction 
    prior to the end of the 30 day notice period, Executive's employment 
    shall not be terminated on that basis.
    
    2.  For purposes of this Agreement a "Change in Employment" shall be 
    deemed to have occurred (a) if (i) Executive's duties are materially 
    adversely changed 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, 
    and (b) if in each case under subsections (a) (i), (ii), and (iii), 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. Executive may elect to treat 
    a Change in Employment as a termination of employment by UHS. 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 
    definitely 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.
    
4.  PROPERTY RIGHTS, CONFIDENTIALITY, NON-SOLICIT AND NON-COMPETE PROVISIONS.

    A.  UHS's PROPERTY.

    own time, during the term of this Agreement. Executive assigns all 
    rights to all such inventions and works of authorship to UHS. Executive

     be valuable, confidential and proprietary and it shall be considered

     Agreement and at all times thereafter Executive shall not use such  
     Confidential Information or disclose it to other persons or entities
