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 Executive accepts such employment on the terms and conditions set forth in this Agreement and, except as specifically superseded by this Agreement, subject to all of UnitedHealth Group's policies and procedures, as changed from time-to-time, in regard to its employees generally.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. 3.

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.

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. 15 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.
