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(i)(i), discounted at an interest rate of 4% per annum 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) The Cash Compensation payable pursuant to the Supplemental Employee Retirement Plan contemplated by Section 2(f) shall be determined as of, and the payments shall commence on, the second anniversary of the termination date.

If Executive, his wife, or his children 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. 4. PROPERTY RIGHTS, CONFIDENTIALITY, NON-SOLICIT AND NON-COMPETE PROVISIONS. (a) UNITEDHEALTH GROUP'S PROPERTY.

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 18 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, knowledge, and information to be valuable, confidential, and proprietary. For purposes of this Agreement, "Confidential Information" shall mean non-public information concerning the financial data, business strategies, product development (and proprietary product data), marketing plans, past, current, or potential customers, providers, and suppliers, and other proprietary information concerning UnitedHealth Group. 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.

(d) NON-COMPETITION. (i) During the term of this Agreement and ending one year after the later of (A) any period for which Executive is receiving payments under Section 3(d), 3(e), 3(f), or 3(g) of this Agreement, notwithstanding any lump-sum payment that Executive might receive 19 under any such Section or (B) the last day in which Executive remains employed by UnitedHealth Group following termination of this Agreement (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, or any subsidiary or affiliated company thereof in which UnitedHealth Group has a more than 20% equity interest (the "UnitedHealth Group Companies"), 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 or any of the UnitedHealth Group Companies were 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 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.

MISCELLANEOUS. (a) DEFINITIONS. For purposes of this Agreement: (i) "Cash Compensation" means the sum of Executive's base annual compensation together with Executive's incentive compensation as hereinafter determined. In determining base annual compensation, the greater of $1,600,000 or the Executive's highest annualized base salary shall be used. Executive's incentive compensation shall equal the average incentive compensation actually earned by Executive for the two years preceding the date of determination for which an incentive determination has been made. Notwithstanding the foregoing, if Executive's severance compensation is paid pursuant to Sections 3(e) or 3(f), then Executive's incentive compensation will equal the greater of the amount determined in accordance with this paragraph or an amount Executive would have been paid at Executive's then target level. In any event, incentive compensation shall include the cash equivalent value at the time earned of any incentive compensation earned and paid or payable in Company Common Stock or other form of consideration. The Special Bonus paid pursuant to Section 2(e) shall be treated as if it were incentive compensation received equally for 1997 and 1998. (ii) "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 remedied such failure within a reasonable time after receipt of such written notice; (B) a violation of United'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 violation; (C) the conviction of Executive of a felony; or (D) any other willful and material breach of 21 this Agreement by Executive that Executive has not remedied within a reasonable time after receipt of a written notice from UnitedHealth 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. (iii) "Change in Control" means (A) the acquisition by an individual, entity or group (within the meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of 1934, as amended (the "Exchange 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. 22 (iii) "Confidential Information" shall have the meaning set forth in Section 4(b). (iv) "Permanent Disability" means Executive's inability by reason of accident, illness, or injury to perform any of the principal duties, responsibilities, or functions of Executive's employment for a period of 180 days or such shorter period as provided in the policy for the Supplemental Long-Term Disability Benefit. (v) "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 Chairman and Chief Executive Officer and as a member of the Board of Directors 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 UnitedHealth Group promptly after receipt of notice thereof given by Executive; (C) any failure of UnitedHealth Group 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) 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 (G) any failure by UnitedHealth Group to comply with and satisfy Section 5(b) of this 23 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. (vi) "Spouse" shall have the meaning set forth in Section 2(g). (b) 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) without the prior written consent of the other party, provided that any assignment by UnitedHealth Group shall not relieve UnitedHealth Group of its obligations under this Agreement. 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. (c) 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: (d) 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 24 have been construed as agreements, between Executive and UnitedHealth Group or any of its subsidiaries and affiliated companies. (e) CHOICE OF LAW. This Agreement shall be construed and interpreted under the applicable laws and decisions of the State of Minnesota. (f) 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. (g) 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. (h) 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 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 25 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. (i) SURVIVAL. The provisions of Sections 2(f), 2(i), 3(c)-3(j), 4 and 5 shall survive any termination of this Agreement pursuant to Section 3(b). THIS AGREEMENT CONTAINS A BINDING ARBITRATION PROVISION THAT MAY BE ENFORCED BY THE PARTIES. UNITEDHEALTH GROUP WILLIAM W.
