SEPARATION AND RELEASE AGREEMENT


     THIS SEPARATION AND RELEASE AGREEMENT ("Release") is made and entered into
between Travers H. Wills ("I," "Me," and "My") and United HealthCare
Corporation, including its present and former subsidiaries and affiliated
corporations ("Employer").

     RECITALS:

     A.   My employment with Employer will terminate on January 1, 1999. 

     B.   It is the Employer's policy to require employees who receive
separation payments to sign a release of claims.  In exchange for the
consideration set forth in this Agreement, I have agreed to the provisions of
this Agreement and to release Employer from any claims arising out of my
employment or termination of employment.

                                      AGREEMENT

     In consideration of the recitals stated above and the mutual promises made
below, Employer and I agree as follows:

1.   TERMINATION.  My last day of work will be January 1, 1999 and my
     termination shall be effective as of that date.  I agree that I will not be
     entitled to any severance payments under my employment agreement.

2.   PAYMENTS.  Employer will pay me my final payroll check for work through
     January 1, 1999.  I will be eligible for the 1998 MIP and will receive any
     additional payment in accordance with company guidelines.

3.   CONSULTING AGREEMENT.  Employer and I have entered into a consulting
     agreement concurrent herewith in the form attached to this agreement
     pursuant to which I will be entitled to receive monthly payments of $49,000
     through July 1, 2000, all in accordance with such agreement.

4.   ADDITIONAL CONSIDERATION.  As additional consideration for my agreement to
     the terms contained herein, Employer agrees to:  continue to vest through
     December 31, 1999 any unvested stock option grants awarded to me under
     Employer's stock option plans.  Such options shall vest (a) at a rate of at
     least 20% of the total number of shares covered by each such option grant
     on the anniversary date of the option grant for grants made before July 1,
     1996; and (b) at a rate of at least 25% of the total number of shares
     covered by each such option grant on the anniversary date of the option
     grant for grants made after July 1, 1996.  In addition the option grant of
     October 1997 will be considered for vesting by March 31, 2000.  I shall
     have until December 31, 2002 to exercise vested options including options
     that vest through December 31, 1999 and the options vesting in 



     the first quarter of 2000.  Employer also agrees to continue health care 
     coverage in accordance with COBRA for an additional 18 months after the 
     date of termination of employment.  Following the COBRA eligibility period,
     Employer agrees to offer me the ability to purchase health insurance under
     the United HealthCare policy at company rates until I am eligible for
     Medicare or become eligible for other health insurance through new
     employment and similarly agrees to offer my spouse the ability so to
     purchase health insurance until my spouse is eligible for Medicare or
     becomes eligible for other health insurance through new employment.  I
     shall be responsible for the premiums payable with respect to such health
     care coverage.  In addition, Employer agrees to pay me the pro rata share
     of Employer's Long Term Incentive Plan for the two-year period ending
     December 31, 1998.  This payment will be made in the Spring of 1999 in
     accordance with the Long Term Incentive Plan.

5.   RELEASE.  In exchange for these payments, I agree to release Employer from
     all claims, demands, actions or liabilities I may have against Employer of
     whatever kind, including but not limited to those which are related to my
     employment with Employer or the termination of that employment.  I agree
     that this also releases from liability Employer's subsidiary and affiliated
     corporations, their predecessors, and each of their present or former
     agents, directors, officers, employees, representatives, shareholders,
     successors and assigns ("those associated with Employer"), whether in their
     official or individual capacities.  I agree that I have executed this
     Release on my own behalf, and also on behalf of any heirs, agents,
     representatives, successors and assigns that I may have now or in the
     future.

     I also agree that this Release covers claims under any federal, state or
     local statute, regulation or common law doctrine regarding or relating to
     employment discrimination, terms and conditions of employment, or 
     termination of employment including, but not limited to, the following: 
     Title VII of the Civil Rights Act of 1964, the Civil Rights Act of 1866,
     the Civil Rights Act of 1991, the Age Discrimination in Employment Act, 
     the Older Workers Benefit Protection Act, the Rehabilitation Act of 1973,
     the Americans With Disabilities Act, the Employee Retirement Income 
     Security Act of 1974, and all applicable amendments; state human rights or
     fair employment practices laws; breach of contract, promissory estoppel, 
     or any other contract theory; defamation, employment negligence, or any 
     other tort theory; and rights in any welfare benefit plan or any pension 
     or retirement plan sponsored by Employer.  However, this Release does not 
     preclude my right to obtain the vested and non-forfeitable balance in my 
     accounts under any pension or retirement plan sponsored by the Employer 
     or preclude me from exercising my right to continuation coverage or my 
     conversion rights, if any, under Employer's welfare benefit plans. 
     
     I also agree that with respect to any released claim(s), that I will never
     file a lawsuit or demand for arbitration, or institute a claim of any kind
     against Employer, or those associated with Employer, including, but not
     limited to, claims 

                                       2



     related to my employment with Employer or the termination of that 
     employment.  Nothing contained herein, however, shall be construed to
     constitute a waiver of future claims, or to prohibit me from seeking 
     recourse through a government agency.  However, this Release includes a 
     release of my right to file a court action or to seek individual remedies
     or damages in any court action filed by any such government agency and my
     release of these rights shall apply with full force and effect to any 
     proceedings arising from or relating to such recourse including, but not 
     limited to, the right to monetary damages or other individual legal or 
     equitable relief awarded by any governmental agency.
     
     If I violate this Release by breaching any of the promises contained 
     herein, including but not limited to filing a lawsuit or demand for 
     arbitration, or instituting a claim against Employer or those associated 
     with Employer, I agree that I will return all separation payments received
     pursuant to this Release.  I further agree that I will pay all costs and 
     expenses of defending against the suit, arbitration, or claim incurred by
     Employer or those associated with Employer, including reasonable attorneys'
     fees. 

     Nothing in the foregoing release, however, shall be construed to limit
     Employer's obligation to indemnify me for my actions while employed by
     Employer as provided in Employer's governing documents or to limit my 
     ability to pursue a claim against Employer for not complying with its 
     indemnification obligations.
     
6.   PERIOD TO CONSIDER SIGNING RELEASE.  I have been given a period of  
     twenty-one (21) days to consider whether I want to sign this Release.

7.   REVOCATION PERIOD.  This Release does not become effective for a period of
     seven days after it is signed by me and I have the right to revoke it 
     during that period.  Any revocation must be in writing and delivered to 
     Robert J. Backes, Senior Vice President, Human Resources, 9900 Bren Road
     East, MN008-8317, Minnetonka, Minnesota, 55343 within the seven-day 
     period. If this person does not RECEIVE a written revocation by the end 
     of the seven-day period, this Release will become fully enforceable at 
     that time.  I understand that if I revoke this Release, I will not be 
     entitled to receive the additional separation payments.

8.   COOPERATION WITH EMPLOYER.  I agree to cooperate with Employer with respect
     to any administrative or legal investigations or proceedings concerning
     matters that arose during my employment.  My cooperation includes making
     myself available to assist with such matters as requested by Employer.  I
     acknowledge that I am not entitled to further compensation or consideration
     from Employer for such cooperation or assistance, except to the extent any
     witness fees are mandated under federal or state law.

9.   CONSULTING AN ATTORNEY.  I acknowledge that I have been advised to 
     consult with an attorney and that any legal consultation will be at my
     own expense. I have 

                                       3



     had adequate opportunity to consult with an attorney, and I have read
     and understand the terms of this Release and am voluntarily signing this
     Release.

10.  CONFIDENTIALITY.  The terms of this Release will be treated as confidential
     by me and Employer and neither of us shall disclose its terms to anyone

     terms of this Release to its officers and directors, outside auditors, and
     to employees or agents of it or its parent corporation who have a 
     legitimate need to know the terms in the course of performing their duties,
     and as required by law.  I recognize and agree that this confidentiality 
     provision was a significant inducement for the Employer to enter into this
     Release.  In the event of a breach by me of the terms of this paragraph, 
     all payments to me shall cease and I shall reimburse all payments made 
     under this Release.

11.  NO FUTURE EMPLOYMENT WITH EMPLOYER.  I agree that I will not, at any time 
     in the future, apply for or accept employment with Employer or any 
     corporation that is an affiliate of Employer.  I agree that any such 
     corporation has the right not to consider my application for future 
     employment and the right to deny me future employment without any 
     recourse.

12.  CONFIDENTIAL OR PROPRIETARY INFORMATION.  During the course of my 
     employment, I may have developed knowledge regarding Employer's 
     organization, strategies, business and operation, and Employer's 
     past, current or potential customers and suppliers.  I acknowledge
     that Employer considers such information to be valuable, confidential,
     and proprietary.  I understand that I may not disclose confidential or 
     proprietary information obtained by me during my employment with Employer.

13.  NON-ADMISSION.  Nothing in this Release is intended to be, nor will be 
     deemed to be, an admission of liability by the Employer that it has 
     violated any state or federal statute, local ordinance, or principle of 
     common law, or that it has engaged in any wrongdoing.

14.  CONTINUATION RIGHTS. All benefits and coverages will cease on the effective
     date of my termination, except in accordance with the terms of the benefit
     plan or applicable law. 

15.  NON-DISPARAGEMENT AND NON-SOLICITATION.  I agree that I will not criticize,
     make any negative comments or otherwise disparage or put in disrepute
     Employer, or those associated with Employer in any way, whether orally, in
     writing or otherwise, directly or by implication in communication with any
     person, including but not limited to customers or agents of Employer.  In
     addition, for the one-year period after I cease receiving any payments
     pursuant to this Release, I agree that I will not directly or indirectly
     recruit, induce, or solicit any employee of Employer for employment. 
     Employer agrees that in response to written inquiries 

                                       4



     concerning my employment, it will provide only my dates of employment and 
     last position held with Employer.

16.  DISCLOSURE.  I acknowledge that I have advised Employer's legal counsel
     completely and candidly of all facts that I am aware of that constitute or
     might constitute violations of Employer's ethical or legal obligations or
     standards. 

17.  INVALIDITY.  In case any one or more of the provisions of this Release 
     shall be invalid, illegal, or unenforceable in any respect, the validity, 
     legality, and enforceability of the remaining provisions contained in this
     Release will not in any way be affected or impaired thereby.

18.  GOVERNING LAW.  This Release will be construed and interpreted in

     this is the entire agreement between me and Employer relating to my
     employment and termination from employment.  This Release includes all

     result of any act or omission of Contractor.  This Section 7 shall survive
     termination of this Agreement.

8.   DISPUTES.  Any dispute relating to or arising under this Agreement shall be
     resolved by binding arbitration pursuant to the Commercial Rules of the

10.  MISCELLANEOUS.  

     A.   ENTIRE AGREEMENT:  This Agreement contains the entire understanding of
          the parties and may be amended only in writing signed by the parties. 
          This Agreement shall supersede any prior agreements between the
          parties in regard to the same subject matter for services rendered
          after the effective date.

          Contractor of the provisions of Sections 4, 5, 9 or 10 of this
          Agreement.  Accordingly, in the event of any actual or threatened

          remedies it may have, be entitled to temporary and/or permanent
          injunctive relief to enforce such provisions, and such relief may be
          granted without the necessity of proving actual damages.

          the remainder of such provision and of this Agreement shall be
          unaffected.  

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