                                     PART I
 
ITEM 1. BUSINESS
 
    UnitedHealth Group is a national leader offering health care coverage and
related services to help people achieve improved health and well-being through
all stages of life. The Company operates in all 50 states, the District of
Columbia, Puerto Rico and internationally. UnitedHealth Group's products and
services reflect a number of core capabilities, including medical information
management, health benefit administration, care coordination, risk assessment
and pricing, health benefit design and provider contracting. With these
capabilities, United is able to provide comprehensive health care management
services through organized health systems and insurance products, including
health maintenance organizations ("HMOs"), point-of-service plans ("POS"),
preferred provider organizations ("PPO") and managed indemnity programs. The
Company also offers specialized health care management services and products
such as behavioral health services, workers compensation and disability
services, utilization review services, specialized provider networks, employee
assistance programs, and knowledge and information services.
 
    UnitedHealth Group is a Minnesota corporation, incorporated in January 1977.
Unless the context otherwise requires, the terms "United," "UnitedHealth Group"
or the "Company" refer to United HealthCare Corporation and its subsidiaries,
which operate under the name of, and is sometimes referred to in this Form 10-K
as, UnitedHealth Group. United's executive offices are located at 300 Opus
Center, 9900 Bren Road East, Minnetonka, Minnesota 55343; telephone (612)
936-1300.
 
                              BUSINESS OPERATIONS
 
    The Company operates in the health and well-being marketplace. In late 1997,
the Company announced an internal realignment that established strategic
business units for each of the Company's six key business lines. These
businesses include UnitedHealthcare, Unimerica, Uniprise, Ovations, Specialized
Care Services and Ingenix. While the Company's general management and various
operational aspects, including information systems and certain administrative
functions, remain interrelated, the realignment allows each business to focus
fully on its specific set of customers and markets. The Unimerica business line
provides insurance services to the other businesses of UnitedHealth Group, and
its results are reported in the segment that originates the business. The
results of UnitedHealthcare and Ovations are combined in one segment.
 
UNITEDHEALTHCARE
 
    UnitedHealthcare operates organized health systems. As of December 31, 1998,
UnitedHealthcare held a majority ownership interest in health plans operating in
approximately 40 markets nationwide and in Puerto Rico. UnitedHealthcare also is
engaged in a joint venture that operates a health plan in the Republic of South
Africa and provides consulting services in Germany, Hong Kong and the
Philippines through this business unit.
 
    For organized health systems it owns, UnitedHealthcare assumes the risk for
health care and administrative costs in return for premium revenue.
UnitedHealthcare's owned health systems usually are licensed as health
maintenance organizations ("HMOs") or insurers. These plans provide
comprehensive health care coverage for a fixed fee or premium that usually does
not vary with the extent of medical services received by the member. Most of
UnitedHealthcare's owned health plans contract with independent providers of
health care services for medical and hospital services. UnitedHealthcare's
health plans that employ health care providers strive for cost-effective
delivery of health care services by emphasizing appropriate use of these
services, promoting preventive health services, and encouraging the use of
clinically proven treatments and best medical practices. UnitedHealthcare also
provides administrative and other management services to a limited number of
health plans in which UnitedHealthcare has no ownership interest.
UnitedHealthcare receives an administrative fee for providing its services to
these plans and generally assumes no responsibility for health care costs.
 
    POINT-OF-SERVICE PRODUCTS.  UnitedHealthcare's point-of-service products are
one of its most popular coverage options. Unlike some traditional HMO products,
which only cover non-emergency services
 
                                       2
<PAGE>
received from contracted providers, point-of-service products also provide
coverage, usually at a lower level, for services received from non-contracted
providers. Sometimes, this out-of-network coverage is offered directly by the
health plan, but more often it is provided by an insurance policy "wrapped
around" the health plan benefit contract. The insurance policy usually is
provided through one of Unimerica's insurance subsidiaries.
 
    SELF-FUNDED PRODUCTS.  UnitedHealthcare has developed self-funded products
for employers who want the cost containment aspects of an organized health
system while self-insuring the health care cost risk. UnitedHealthcare uses the
provider networks it has developed for its health plan or insurance products for
its self-funded products, many of which include a point-of-service feature. The
provider contracts for these products are with individual physicians, groups of
physicians and health care facilities and are generally on a standard
fee-for-service basis. With self-funded products, employers and other sponsoring
groups have access to a provider network and the administrative and care
coordination services associated with an organized health system product, but
the sponsoring company or group generally bears the financial costs associated
with the health care.
 
    MEDICARE+CHOICE PLANS.  Several of UnitedHealthcare's owned health plans
contract with the federal Health Care Financing Administration ("HCFA") to
provide coverage for Medicare-eligible individuals. Under these contracts, plans
receive a fixed monthly payment from HCFA for each enrolled individual and must
provide at least the benefits that would be covered under traditional Medicare.
The plans provide a significantly higher level of coverage and may, but often do
not, charge an additional monthly premium to the members for the greater
benefits. The health plans generally use a subset of their commercial product
provider network as the provider network for the Medicare products. Any
Medicare-eligible person in a plan's service area may enroll in the Medicare
product without underwriting or health screening. Features such as United Health
Passport allow members to travel to other UnitedHealthcare Medicare sites and
receive their same benefits.
 
    Some of UnitedHealthcare's health plans also offer these Medicare products
to or through employer groups as a way of providing retiree health care
coverage.
 
    MEDICAID PRODUCTS.  Several of UnitedHealthcare's health plans offer
coverage to Medicaid-eligible individuals. These plans typically contract with a
state agency to provide such coverage and receive a fixed monthly payment for
each enrolled individual. The level of benefits generally is set by contract,
and few additional benefits are offered. Enrollment usually must be offered to
all eligible individuals without underwriting or health screening. Generally,
the provider network for commercial products is used, but some providers may
refuse to participate in the Medicaid product and the network may have a
different number or set of providers for other reasons.
 
OVATIONS
 
    Ovations includes the Company's operations that target the market segment
comprised of people age 50 and older. These operations include Medigap and
Medicare supplement products, the EverCare-Registered Trademark- program and the
Company's relationship with AARP.
 
    AARP.  In early 1997, the Company finalized a 10-year agreement with the
American Association of Retired Persons ("AARP") to underwrite Medicare and
hospital supplement insurance products effective January 1, 1998. During 1997,
the Company coordinated the transfer of the operations from AARP's existing
vendor and prepared to implement this contract. As of January 1, 1998, the
Company's insurance subsidiaries assumed the underwriting risk, and Ovations
assumed the claim administration associated with the business.
 
    EVERCARE-REGISTERED TRADEMARK-.  The EverCare-Registered Trademark- program
coordinates the provision of a broad spectrum of health care services primarily
to permanent nursing home residents through employed and contracted physicians
and nurse practitioners. EverCare is participating in a demonstration project
with HCFA to offer health care services to the elderly nursing home residents in
several separate locations throughout the country.
 
                                       3
<PAGE>
UNIMERICA
 
    Unimerica is UnitedHealth Group's insurance arm, which serves as the legal
insurer for insurance products offered through UnitedHealth Group businesses.
Unimerica's insurance subsidiaries are licensed in all 50 states, the District
of Columbia, Puerto Rico, Guam and the Virgin Islands.
 
    UnitedHealth Group reports the revenues from insurance products in the
segments that originate the business, not in Unimerica. Through these insurance
subsidiaries, Unimerica offers Options PPO, a national preferred provider
organization product. Options PPO combines access to UnitedHealthcare's
commercial health plan networks and certain specialty services with managed
indemnity coverage. Individuals covered under the Options PPO product have lower
out-of-pocket costs when they obtain covered services from contracted providers,
but also have the option to go outside of the network for covered services.
 
    For customers with less than 50 employees, Unimerica typically sells its
products on an insured basis for a fixed premium, with no experience adjustments
made to the premium. This type of business often has been subject to sudden and
unpredictable changes in health care costs and generally has high administrative
and marketing expenses. In addition, these products are subject to extensive
state regulations. For larger customers, Unimerica sells these products on both
an insured and self-funded basis. The insured products often are sold on an
experience-rated basis, and the self-funded products usually are sold on an
administrative fee basis. In some cases, the agreement with the customer
includes penalties or rewards related to administrative service standards and/or
health care costs.
 
    Unimerica's insurance subsidiaries also offer several health insurance
products in conjunction with health plan products. These products help employers
replace multiple health care policies and vendors with a single health care
plan. These subsidiaries also offer reinsurance and other insured products on a
selective basis to most of UnitedHealthcare's health plans and to employers and
other sponsoring groups offering self-funded health care benefit plans. Under an
agreement with Metropolitan Life Insurance Company ("MetLife"), UnitedHealth
Group businesses offers MetLife's life, dental, accidental death and
dismemberment and short-term disability products to customers, and MetLife
offers UnitedHealth Group's health care coverage products to MetLife customers.
This agreement with MetLife also contains certain exclusivity and
non-competition provisions.
 
UNIPRISE
 
    Uniprise focuses on UnitedHealth Group's business with large employers. Its
core competencies include sales and account management, benefits administration
and customer services, including government-related operations, and care
management.
 
    Uniprise provides sales and account management services to more than 200
customers, approximately 50 percent of which are Fortune 500 companies.
UnitedHealth Group's network-based medical and insurance products and
specialized care services are available to these customers, with various types
of funding arrangements. Uniprise specializes in serving the needs of large
multi-site employers, and offers long-term strategic health care coverage
planning to its customers.
 
    The operations unit of Uniprise provides benefits administration services
and customer services to UnitedHealth Group customers in its other business
lines. Benefits administration services include enrollment, eligibility, claims
processing, and billing. Customer services include telephonic information,
provider directories and identification card production, and oversight of the
government operations and care management centers divisions.
 
    The government operations division provides Medicare Part A services for
hospitals and nursing homes in Connecticut, New York and Michigan and Medicare
Part B services for beneficiaries and providers in Connecticut, Minnesota,
Mississippi and Virginia. This division also provides specialized claims
processing services for durable medical equipment in 10 northeastern states.
This unit serves as the national Medicare Part B carrier for the Railroad
Retirement Board. In addition, at the request of the Office of Personnel
Management and HCFA, the government operations division contracts with all
 
                                       4
<PAGE>
insurance carriers involved in the administration of the Federal Employee Health
Benefit Plan ("FEHBP").
 
    The care management centers division offers customers medical management
programs designed to improve patients' clinical outcomes, reduce medical
expenses, and increase consumer satisfaction. These services include utilization
review, review of hospital-based services, and the administration of high-impact
medical programs based upon customer-specific demographic and claims data.
 
SPECIALIZED CARE SERVICES
 
    Specialized Care Services is a portfolio of businesses that focus on
specific aspects of health and well-being. These businesses sell its products
and services to and through other UnitedHealth Group businesses as well as to
independent entities such as HMOs, PPOs, insurers, Blue Cross/Blue Shield plans,
third-party administrators, employers, labor unions and/or government agencies.
These businesses generally receive fees for the services they provide, which are
primarily administrative in nature. Specialized Care Services assumes no
responsibility for health care costs except for certain behavioral health
products. These businesses assume some responsibility for health care costs
related to providing mental health/substance abuse services.
 
    BEHAVIORAL HEALTH SERVICES.  Specialized Care Services provides behavioral
health services through United Behavioral Health ("UBH"), which offers
behavioral health care management services, employer assistance programs, and
psychiatric disability management services through specialized provider networks
and behavioral health care managers. UBH customers include most of
UnitedHealthcare's health plans, private and public sector employers and
government agencies. These services are provided by a national network of
contracted providers. United assumes the responsibility for health care costs
related to some of these services. UBH serves approximately 14 million
individuals.
 
    HEALTH INFORMATION, EDUCATION AND SUPPORT SERVICES.  Specialized Care
Services provides health information, education and related services through
Optum-Registered Trademark-. Optum offers a full spectrum of counseling, access
and consumer information services for helping individuals manage their health
and well-being. Its services are available via 24-hour telephone information
lines, publications, audiotapes, face-to-face meetings and the Internet. Optum
services are available to approximately 15 million individuals.
 
    TRANSPLANT SERVICES.  Specialized Care Services offers transplant services
through United Resource Networks. United Resource Networks offers clients access
to a network of health care facilities for transplant-related services and
transplant care management services. United Resource Networks negotiates fixed,
competitive rates for high-cost, low-frequency health care services such as
organ and tissue transplants. United Resource Networks serves 450 clients,
representing approximately 37 million individuals.
 
INGENIX
 
    Ingenix builds upon UnitedHealth Group's heritage of using its large
database and expertise to provide knowledge and information services to
providers, drug and device manufacturers, the government, payers, employers and
other interested organizations. It was formed by combining UnitedHealth Group's
information-related businesses and capabilities and expanded through several
acquisitions, as well as internal growth.
 
    Ingenix provides four broad types of products and services:
 
    CONSULTING.  Ingenix provides consulting services to providers, payers,
employers and other health system participants focusing on actuarial and
financial matters, product development, provider contracting, and medical policy
and management.
 
    PHARMACEUTICAL SERVICES.  Ingenix performs clinical trials services and
outcomes and pharmacoeconomic research for pharmaceutical and medical device
manufacturers globally. Services
 
                                       5
<PAGE>
include helping find and train investigators and recruit patients, developing
research protocols, providing regulatory assistance, data collection and
management, biostatistics, and general project management.
 
    PUBLISHING.  Ingenix's publications unit sells print and electronic media
products that provide information regarding coding, reimbursement, billing,
compliance and other general health care issues.
 
    SOFTWARE, DATA AND SERVICES.  Ingenix's software, data and services include
databases for benchmarking, software to analyze and report cost and utilization
of services, data management services, HEDIS reporting, fraud and abuse
services, claims editing software, and reimbursement systems audits.
 
                    EXPANSION AND DIVESTITURE OF OPERATIONS
 
    United continually evaluates expansion opportunities and often considers
whether to divest or stop offering certain of its businesses or products.
Expansion opportunities may include acquiring specialized care services programs
or insurance and health plan operations. United also devotes significant
attention to developing new products and techniques for managing health care
costs, measuring the outcomes and efficiency of health care delivered, and
coordinating and managing health care delivery systems. As part of its expansion
efforts, in 1998 the Company earmarked $35 million from the Company's corporate
usable cash reserves to invest in and help develop small but promising ventures.
 
    During 1998, the Company completed several acquisitions and also sold or
terminated certain lines of business and ceased offering some products, all as
part of its ongoing emphasis on its strategic focus. If the Company were to make
numerous acquisitions, it may affect its ability to integrate and manage its
overall business effectively. Integration activities relating to acquisitions
may increase costs, affect membership, affect revenue and earnings growth and
adversely affect United's financial results.
 
                             GOVERNMENT REGULATION
 
    United's primary business, offering health care coverage and health care
management services, is heavily regulated at both the federal and state level.
United believes it complies in all material respects with the various federal
and state regulations that apply to its current operations. To maintain
compliance, United or a subsidiary may make occasional changes in its services,
products, organizational or capital structure, or marketing methods.
 
    Government regulation of health care coverage products and services is a
changing area of law that varies from jurisdiction to jurisdiction. Regulatory
agencies generally have broad discretion to issue regulations and interpret and
enforce laws and rules. Changes in applicable laws and regulations are
continually being considered, and the interpretation of existing laws and rules
also may change periodically. These regulatory revisions could affect United's
operations and financial results. Certain proposed changes in Medicare and
Medicaid programs may improve opportunities to enroll people under products
developed for the senior populations. Other proposed changes may limit available
reimbursement and increase competition in those programs, with adverse effects
on United's financial results. Also, it may be more difficult for United to
control medical costs if federal and state bodies continue to consider and enact
significant and sometimes onerous managed care laws and regulations. Examples of
such laws are medical malpractice liability laws for health plans; mandates
requiring health plans to offer point-of-service plans and other benefits such
as direct access and formulary restrictions; limits on contractual terms with
providers, including termination provisions; implementation of a mandatory third
party review process for certain coverage denials and other laws and limits on
utilization management.
 
    HIPPAA.  The Health Insurance Portability and Accountability Act of 1996
("HIPAA") may represent the most significant federal reform of employee benefits
law since the enactment of the Employee Retirement Income Security Act ("ERISA")
in 1974. HIPAA's federal standards apply to both the group and individual health
insurance markets, including self-insured employee benefit plans. Some of
HIPAA's significant provisions include guarantees of the availability of health
insurance for certain employees and individuals; limits on the use of
preexisting condition exclusions; prohibitions against discriminating on the
basis of health status; and requirements which make it easier to continue
coverage in cases where an
 
                                       6
<PAGE>
employee is terminated or changes employers. While United currently believes
that it is in material compliance with the requirements of HIPAA, the law is far
reaching and complex, and the federal agencies involved in the enforcement of
HIPAA's provisions have been slow to provide guidance regarding HIPAA's
requirements in the form of final rules and regulations. Consequently, United's
efforts to measure, monitor, and adjust its business practices to comply with
HIPAA are ongoing. Further, significant enforcement responsibilities for HIPAA's
provisions have been given to the states. It is likely that United will
encounter different interpretations of HIPAA's provisions in the different
states as well as varying enforcement philosophies which may inhibit United's
ability to standardize its products and services across state lines. Ultimately,
under HIPAA and other state laws, cost control through provider contracting and
coordinating care may become more important, and United believes its experience
in these areas will allow it to compete effectively.
 
    FRAUD AND ABUSE.  Health care fraud and abuse have become a top priority for
the nation's law enforcement entities. The funding of such law enforcement
efforts has increased dramatically in the past few years and is expected to
continue. The focus of these efforts has been directed at participants in
federal government health care programs such as Medicare, Medicaid and FEHBP.
United participates extensively in these programs. The regulations and
contractual requirements applicable to participants in these programs are
extremely complex and ever changing. In light of this environment, United has
re-emphasized its regulatory compliance efforts for these programs; however, the
programs are subject to highly technical rules. When combined with law
enforcement intolerance for any level of noncompliance, these rules mean that
compliance efforts in this arena continue to be challenging.
 
    AUDITS AND INVESTIGATIONS.  United also is subject to governmental audits,
investigations and enforcement actions. These include possible government
actions relating to ERISA, which regulates insured and self-insured health
coverage plans offered by employers and United's services to such plans and
employers; FEHBP; federal and state fraud and abuse laws; state insurance or
licensing laws; laws relating to utilization management and the delivery of
health care; and laws relating to Medicare, including ACR development, special
payment status, payments for emergency room visits, and various other areas. Any
such government actions could result in assessment of damages, civil or criminal
fines or penalties, or other sanctions, including exclusion from participation
in government programs. United is currently involved in various government
investigations, audits and reviews, some of which are under FEHBP, ERISA, and
the authority of state departments of insurance. United does not believe the
results of current audits, individually or in the aggregate, will have a
material adverse effect on its financial position or results.
 
    HMOS.  All of the states in which United's health plans offer HMO products
regulate the activities of those health plans. Most states require periodic
financial reports from entities licensed to operate as HMOs in their states and
impose minimum capital or reserve requirements. Some of United's health plan and
insurance subsidiaries must maintain specified capital levels to support their
operations. In addition, state regulatory agencies require some United health
plans and insurance subsidiaries to maintain restricted cash reserves
represented by interest-bearing instruments, which are held by trustees or state
regulatory agencies to ensure that each subsidiary maintains adequate financial
reserves. Some state regulations allow agencies to review all contracts entered
into by HMOs, including management contracts and agreements between affiliates,
for reasonableness of fees charged and other provisions.
 
    United's health plans that have Medicare risk contracts are regulated by
HCFA. HCFA has the right to audit health plans operating under Medicare risk
contracts to determine each health plan's compliance with HCFA's contracts and
regulations and the quality of care being given to the health plan's members. To
enter into Medicare risk contracts, a health plan must be either federally
qualified or considered a Competitive Medical Plan under HCFA's requirements.
Health plans that offer a Medicare risk product also must comply with
requirements established by peer review organizations ("PROs"), which are
organizations under contract with HCFA to monitor the quality of health care
Medicare beneficiaries receive. PRO requirements relate to quality assurance and
utilization review procedures. United's health plans that have Medicare cost
contracts are subject to similar regulatory requirements. In addition, these
 
                                       7
<PAGE>
health plans must file certain cost reimbursement reports with HCFA, which are
subject to audit and revision.
 
    United's health plans that have Medicaid contracts are subject to federal
and state regulation regarding services to be provided to Medicaid enrollees,
payment for those services, and other aspects of the Medicaid program. Both
Medicare and Medicaid have, or have proposed, regulations relating to fraud and
abuse, physician incentive plans, and provider referrals that could affect
United's operations.
 
    Many of United's health plans have contracts with FEHBP. These contracts are
subject to extensive regulation, including complex rules regarding premiums
charged. FEHBP is authorized to audit the rates charged retroactively and seek
premium refunds or institute other sanctions against health plans that
participate in the program, depending on the outcome of such audits.
 
    INSURANCE REGULATION.  United's insurance subsidiaries and most of the
Company's health plans are regulated by the department of insurance or
equivalent agency in each state or other jurisdiction in which the entity is
licensed. Regulatory authorities have extensive supervisory power regarding:
licensing; the amount of reserves that must be maintained; the approval of
insurance policy forms; the nature of, and limits on, insurance company
investments; periodic examination of insurance company operations; the form and
content of annual statements and other required reports on the financial
condition of insurance companies; and the capital requirements for insurance
companies. United's insurance company subsidiaries must file periodic statutory
financial statements in each jurisdiction in which they are licensed.
Additionally, these companies are periodically examined by the insurance
departments or equivalent agencies of the jurisdictions in which they are
licensed to do business.
 
    INSURANCE HOLDING COMPANY REGULATIONS.  Many of United's health plans and
each of United's insurance subsidiaries are regulated under state insurance
holding company regulations. Insurance holding company laws and regulations
generally require registration with the state department of insurance and the
filing of certain reports that describe capital structure, ownership, financial
condition, certain intercompany transactions and general business operations.
Various notice, reporting and pre-approval requirements generally apply to
transactions between companies within an insurance holding company system,
depending on the size and nature of the transactions. Some state insurance
holding company laws and regulations require prior regulatory approval or, in
certain circumstances, prior notice of acquisitions, and certain material
intercompany transfers of assets, as well as certain transactions between the
regulated companies and their parent holding companies or affiliates.
 
    TPAS.  Certain subsidiaries of United also are licensed as third-party
administrators ("TPAs") where required. TPA regulations differ greatly from
state to state, but generally contain certain required administrative
procedures, periodic reporting obligations and minimum financial requirements.
 
    PPOS.  Some United subsidiaries or products may be subject to PPO regulation
in a particular state. PPO regulations generally contain network, contracting,
financial and reporting requirements, which vary from state to state.
 
    UTILIZATION REVIEW REGULATIONS.  Many states have enacted laws and/or
adopted regulations governing utilization review activities, and these laws may
apply to some United operations. Generally, these laws and regulations set
specific standards for delivery of services, confidentiality, staffing and
policies and procedures of private review entities, including the credentials
required of personnel.
 
    MCOS.  Many states have enacted laws that allow self-insured employers
and/or insurance carriers to use a state-certified managed care organization
("MCO") to apply medical management and other managed care techniques to the
medical benefit portion of workers' compensation. United's subsidiaries
generally have sought MCO certification in states where it is available and
where they market managed care workers compensation products. MCO laws differ
significantly from state to state, but generally address network and utilization
review activities.
 
    ERISA.  ERISA regulates how goods and services are provided to or through
certain types of employee health benefit plans. ERISA is a complex set of laws
and regulations that is subject to periodic
 
                                       8
<PAGE>
interpretation by the United States Department of Labor. ERISA places controls
on how United's business units may do business with employers covered by ERISA,
particularly employers that maintain self-funded plans. The Department of Labor
has an ongoing ERISA enforcement program, which may result in additional
constraints on how ERISA-governed benefit plans conduct their activities. There
recently have been legislative attempts to limit ERISA's preemptive effect on
state laws. Such limitations could increase United's liability exposure under
state law-based suits relating to employee health benefits offered by United's
health plans and specialty businesses and permit greater state regulation of
other aspects of those businesses' operations.
 
                              YEAR 2000 ACTIVITIES
 
    Our business depends significantly on effective information systems, and we
have many different information systems for our various businesses. Our
information systems require ongoing enhancements to keep pace with the
continuing changes in information technology, evolving industry standards, and
customer preferences. We have been modifying our computer systems to accommodate
the Year 2000. The Year 2000 problem exists throughout the global marketplace,
as many computer systems and applications were developed to recognize the year
as a two-digit number, with the digits "00" being recognized as the year 1900.
 
    Starting in 1995, our formal Year 2000 Project Office began implementing a
remediation plan to ensure that critical information systems applications,
end-user developed application tools, and critical business interfaces remain
intact, and can function properly through the century change. We are on schedule
to complete, test, and certify our Year 2000 remediation efforts by September
30, 1999. A more detailed description and current status of our Year 2000
activities follows.
 
TECHNICAL INFRASTRUCTURE
 
    MAINFRAME TECHNOLOGY.  In conjunction with our two vendors that provide
support for our data center operations, we have completed, tested and certified
99% of our remediation efforts for the hardware, operating system and supporting
software remediation efforts on our two primary mainframe computer systems. In
addition, we are in the process of reviewing some of our smaller mainframe
systems and making modifications as necessary. We expect to be 100% complete
with all mainframe hardware and software technology Year 2000 modifications by
March 31, 1999. We also have installed separate test environments (both
mainframe and distributed) to test our business applications in a simulated Year
2000 environment.
 
    DESKTOP HARDWARE & SOFTWARE.  We have inventoried all of our desktop
hardware and software--over 40,000 computing devices of multiple makes and
models. All non-compliant desktop hardware and software have been identified and
are being modified or replaced with compliant systems by September 30, 1999.
 
    TELECOMMUNICATIONS.  We have inventoried all of our telecommunication
systems--more than 28,000 telecommunication devices, including traffic routers
and phone switches. We are using two outside vendors to assist us in modifying
or replacing non-compliant telecommunication systems. As of December 31, 1998,
we were approximately 75% Year 2000 compliant with our data and voice networks.
We expect all our telecommunication networks and devices will be Year 2000
compliant by September 30, 1999.
 
BUSINESS APPLICATIONS
 
    SOFTWARE APPLICATIONS.  We use 500 different software applications that
include over 80 million lines of computer code. We have surveyed our software
applications and have identified systems that will not be used after December
31, 1999, and systems that will be modified for Year 2000 compliance. We have
determined that 36% of our software applications will not be used after December
31, 1999 due to conversions, consolidations and software replacements. Of the
remaining applications, over 90% have been made Year 2000 compliant, tested and
certified or are scheduled to be certified for compliance. The
 
                                       9
<PAGE>
balance of the applications are yet to be tested. We expect all critical Year
2000 software modifications to be completed by March 31, 1999, with further
testing and certification during the remainder of 1999.
 
    END-USER DEVELOPED APPLICATIONS.  End-user developed applications are
analysis tools that have been internally developed by individual employees or
operating segments primarily running on personal computers or client servers.
The Year 2000 Project Office has continuously communicated with all employees
explaining the risks of non-compliant applications and provided tools and
techniques to make them compliant. We have identified and are tracking and
assessing Year 2000 compliance issues with respect to all potentially critical
end-user applications.
 
OTHER YEAR 2000 MATTERS
 
    NON-INFORMATION TECHNOLOGY SYSTEMS.  We have approximately 300 owned or
leased facilities throughout the world. We have contacted all of our facility
managers regarding Year 2000 compliance issues. In addition, we have contracted
with a real estate management company to assist in our Year 2000 compliance
efforts. All facilities are scheduled to be Year 2000 compliant by September 1,
1999.
 
    DEPENDENCE ON THIRD PARTIES.  We have a contractual relationship with
approximately 300,000 different medical providers and more than 92,000 vendors.
Approximately 2,000 vendors have been identified as critical business partners
and suppliers. We are currently in communication with these critical business
partners to analyze their Year 2000 compliance efforts. We expect to complete
our analysis of critical vendor readiness and identify alternative vendors,
where necessary, by July 31, 1999. We will not be individually contacting all of
the 300,000 medical providers we conduct business with regarding Year 2000
compliance issues. However, we will be testing and verifying the electronic
collection of data with these providers through our EDI (electronic data
interface) clearinghouse vendors.
 
    COSTS OF YEAR 2000 COMPLIANCE.  The projected costs of our Year 2000
compliance efforts and the date on which we plan to complete the necessary Year
2000 remediation efforts are based on management's best estimates, which were
derived utilizing various assumptions of future events. However, there can be no
guarantee that these estimates will be achieved and actual results could differ
significantly from our current plans. Specific factors that might cause
significant differences include, but are not limited to, the availability and
cost of personnel trained in this area, the ability to locate and correct the
relevant computer codes, and the ability of our significant vendors, providers,
customers and others with whom we conduct business to identify and resolve their
own Year 2000 issues.
 
    Costs associated with modifying internal use software for Year 2000
compliance are charged to expense as incurred. Purchases of hardware or software
that replace existing hardware or software that is not Year 2000 compliant are
capitalized and amortized over their useful lives. As of December 31, 1998, our
historical and projected costs to complete our Year 2000 remediation plan are as
follows (in millions):

</TABLE>
 
    BUSINESS RISKS OF NON-COMPLIANT SYSTEMS.  Although we are committed to
completing and testing our remediation plan well in advance of the Year 2000,
there are risks if we do not meet our objectives by December 31, 1999.
Operationally, the most severe risk is business interruption. Specific examples
of
 
                                       10
<PAGE>
situations that could cause business interruption include, but are not limited
to: 1) computer hardware or application software processing errors or failures,
2) facilities or infrastructure failures, or 3) critical outside providers,
suppliers, or customers who may not be Year 2000 compliant. Depending on the
extent and duration of business interruption resulting from non-compliant Year
2000 systems, such interruption may have a material adverse effect on our
results of operations, liquidity, and financial condition.
 
    CONTINGENCY PLANS.  Each area of our Year 2000 compliance effort is
currently developing contingency plans to mitigate the risk of failure, and to
provide for a speedy recovery from possible failures associated with the century
change. The contingency plans detail strategies to implement in 1999 to prepare
for the century rollover, and actions to execute if problems arise. The target
date for completion of the initial contingency plans is April 1, 1999.
Contingency plans will be final by July 31, 1999.
 
                                   MARKETING
 
    The Company's marketing strategy is defined and coordinated by each
functional business unit's dedicated marketing staff. Within these business
units, primary marketing responsibility generally resides with a marketing
director and a direct sales force. In addition, several of the business units
rely upon independent insurance agents and brokers to sell some of the Company's
health plan, insurance, self-funded and specialized care products. Marketing
efforts also include public relations efforts and advertising programs that may
use television, radio, newspapers, magazines, billboards, direct mail and
telemarketing.
 
                                  COMPETITION
 
    The managed health care industry evolved primarily because of health care
buyers' concerns about rising health care costs. The industry has brought
greater cost effectiveness and accountability into the health care system
through managed care products, including health plans, PPOs, and specialized
services such as mental health or pharmacy benefit programs. The industry also
has helped increase the accessibility and quality of health care services.
 
    United operates in a highly competitive environment. Significant
consolidation has occurred within the managed care industry, creating stronger
and more diverse competitors. At the same time, new competitors have entered the
marketplace, which also may increase competitive pressures. In certain areas,
current competition may limit United's ability to price its products at levels
United believes appropriate. These competitive factors could adversely affect
United's financial results.
 
    As managed health care penetration of the health care market and the effects
of health care reforms continue to increase nationwide, the Company expects it
may become increasingly difficult to obtain new contracts for its health plans
with large employer and government groups. The Company also expects competition
for smaller employer groups to intensify. In addition, employers increasingly
may choose to self-insure the health care risk, while seeking benefit
administration and utilization review services from third parties to help them
control and report health care costs.
 
    The Company's business lines compete for group and individual membership
with other health insurance plans, Blue Cross/Blue Shield plans, health plans,
HMOs, PPOs, third party administrators, health care management companies, and
employers or groups that elect to self-insure. The Company also faces
competition from hospitals, health care facilities, and other health care
providers who have formed their own networks to contract directly with employer
groups and other prospective customers for the delivery of health care services.
The number and strength of the Company's competitors varies for each particular
business unit and geographic area. The Company believes that the principal
competitive factors affecting the Company and its products include price, the
level and quality of products and service, provider network capabilities, market
share, the offering of innovative products, product distribution systems,
efficient administration operations, financial strength and marketplace
reputation.
 
    The Company currently believes that its competitive strengths include the
breadth of its product line, its geographic scope and diversity, the strength of
its underwriting and pricing practices and staff, its significant market
position in certain geographic areas, the strength of its distribution network,
its financial
 
                                       11
<PAGE>
strength, its generally large provider networks that provide more member choice,
its point-of-service products and experience, and its generally favorable
marketplace reputation. In some markets, however, the Company may be at a
disadvantage because of competitors with larger market shares, broader networks,
narrower networks (which may allow greater cost control and lower prices) or a
more-established marketplace name and reputation. The Company believes its
recent operational realignment will allow the individual business units to more
effectively compete in their respective markets.
 
                                   EMPLOYEES
 
    As of December 31, 1998, the Company employed approximately 29,226
individuals. As of December 31, 1998, approximately 239 of the Company's
employees were represented by a union. The Company believes its employee
relations are good.
 
                             CAUTIONARY STATEMENTS
 
    The statements contained in this Form 10-K, and the Management's Discussion
and Analysis of Financial Condition and Results of Operation and other sections
of the Company's annual report to shareholders incorporated by reference in this
document, include forward-looking statements within the meaning of the Private
Securities Litigation Reform Act of 1995 (the "PSLRA"). When used in this Form
10-K and in future filings by the Company with the Securities and Exchange
Commission, in the Company's press releases, presentations to securities
analysts or investors, and in oral statements made by or with the approval of an
executive officer of the Company, the words or phrases "believes,"
"anticipates," "intends," "will likely result," "estimates," "projects" or
similar expressions are intended to identify such forward-looking statements.
Any of these forward-looking statements involve risks and uncertainties that may
cause the Company's actual results to differ materially from the results
discussed in the forward-looking statements.
 
    The following discussion contains certain cautionary statements regarding
our business that investors and others should consider. This discussion is
intended to take advantage of the "safe harbor" provisions of the PSLRA. In
making these cautionary statements, we are not undertaking to address or update
each factor in future filings or communications regarding our business or
results, and are not undertaking to address how any of these factors may have
caused results to differ from discussions or information contained in previous
filings or communications. In addition, any of the matters discussed below may
have affected the Company's past, as well as current, forward-looking statements
about future results. The Company's actual results in the future may differ
materially from those expressed in prior communications.
 
    HEALTH CARE COSTS.  We use a large portion of our revenue to pay the costs
of health care services or supplies delivered to our members. Total health care
costs we incur are affected by the number of individual services rendered and
the cost of each service. Much of our premium revenue is priced before services
are delivered and the related costs are incurred, usually on a prospective
annual basis. Although we try to base the premiums we charge in part on our
estimate of future health care costs over the fixed premium period, competition,
and regulations and other circumstances may limit our ability to fully base
premiums on estimated costs. In addition, many factors may and often do cause
actual health care costs to exceed what was estimated and reflected in premiums.
These factors may include increased use of services, increased cost of
individual services, catastrophes, epidemics, the introduction of new or costly
treatments, general inflation, new mandated benefits or other regulatory
changes, and insured population characteristics. In addition, the earnings we
report for any particular quarter include estimates of covered services incurred
by our enrollees during that period for claims that have not been received or
processed. Because these are estimates, our earnings may be adjusted later to
reflect the actual costs. Relatively insignificant changes in the medical care
ratio, because of the narrow margins of our health plan business, can create
significant changes in our earnings.
 
    Our medical care ratio has generally increased over the past several fiscal
periods. We are addressing the medical care ratio by altering benefit designs,
recontracting with providers, and aggressively increasing
 
                                       12
<PAGE>
both our contemporaneous and retrospective claim management activities. Our
inability to implement these changes successfully could lead to further
increases in our medical care ratio.
 
    In addition, our operating results may be affected by the seasonal changes
in the level of health care use during the calendar year. Although there are no
assurances, per member medical costs generally have been higher in the first
half than in the second half of each year.
 
    INDUSTRY FACTORS.  The managed care industry receives significant negative
publicity. This publicity has been accompanied by increased legislative
activity, regulation and review of industry practices. These factors may
adversely affect our ability to market our products or services, may require us
to change our products and services, and may increase the regulatory burdens
under which we operate, further increasing the costs of doing business and
adversely affecting profitability.
 
    COMPETITION.  In many of our geographic or product markets, we compete with
a number of other entities, some of which may have certain characteristics or
capabilities that give them a competitive advantage. We believe the barriers to
entry in these markets are not substantial, so the addition of new competitors
can occur relatively easily, and consumers enjoy significant flexibility in
moving to new managed care providers. Certain Company customers may decide to
perform functions or services we provide for themselves, which would decrease
our revenues. Certain Company providers may decide to market products and
services to our customers in competition with us. In addition, significant
merger and acquisition activity has occurred in the industry in which we operate
as well as in industries that act as suppliers to us, such as the hospital,
physician, pharmaceutical and medical device industries. To the extent that
there is strong competition or that competition intensifies in any market, our
ability to retain or increase customers or providers, or maintain or increase
our revenue growth, pricing flexibility, control over medical cost trends and
our marketing expenses may be adversely affected.
 
    AARP CONTRACT.  Under our long-term contract with the American Association
of Retired Persons ("AARP"), we provide Medicare supplemental, hospital
indemnity health insurance and other products to AARP members. As a result of
the agreement, the number of members we serve, products we offer, and services
we provide has grown significantly. Our portion of the AARP's insurance program
represents approximately $3.5 billion in annual net premium revenue from
approximately 4 million AARP members. The success of the AARP arrangement will
depend, in part, on our ability to service these new members, develop additional
products and services, price the products and services competitively, and
respond effectively to federal and state regulatory changes. Additionally,
events that adversely affect the AARP could have an adverse effect on the
success of our arrangement with the AARP.
 
    MEDICARE OPERATIONS.  In the second quarter of 1998, we experienced a
significant rise in the medical care ratio for our Medicare operations. The
increase in medical costs was primarily due to the business growth in new
markets with higher and more volatile medical cost trends, coupled with lower
reimbursement rates. In response, we announced in October 1998 our decision to
withdraw Medicare product offerings from 86 of the 206 counties we currently
serve. The decision, effective January 1, 1999, will affect approximately
60,000, or 13%, of current Medicare members. As a consequence of this
withdrawal, we are precluded from re-entering these counties with Medicare
product offerings until 5 years after the effective date.
 
    We will continue to offer Medicare products in strong and economically
viable markets. However, our ability to improve the financial results of all of
our Medicare operations will depend on a number of factors, including future
premium increases, growth in markets where we have achieved sufficient size to
operate efficiently, benefit design, provider contracting, and other factors.
There can be no assurance that we will be able to successfully prevent future
losses on our Medicare operations.
 
    REALIGNMENT OF OPERATIONS.  We recognized a charge to earnings in the second
quarter of 1998 for our realignment. In January 1998, we initiated a significant
realignment of our operations into six business lines. As part of the
realignment, we began shifting resources and activities to more directly support
the operations of our businesses. Although we do not expect our realignment
efforts to negatively affect our product offerings, provider relations, billing
and collection disciplines, claims processing and payment
 
                                       13
<PAGE>
activities, or other business functions, there can be no assurance that such
negative effects may not occur. Our second quarter charge to earnings for costs
associated with the realignment was $725 million. Although we believe such
charges are adequate, there can be no assurance that the costs associated with
our realignment efforts will not exceed the charges we have taken for such
costs.
 
    GOVERNMENT PROGRAMS AND REGULATION.  Our business is heavily regulated on a
federal, state and local level. The laws and rules governing our business and
interpretations of those laws and rules are subject to frequent change. Broad
latitude is given to the agencies administering those regulations. Existing or
future laws and rules could force us to change how we do business, restrict
revenue and enrollment growth, increase its health care and administrative costs
and capital requirements, and increase our liability for medical malpractice or
other actions. We must obtain and maintain regulatory approvals to market many
of our products. Delays in obtaining or failure to obtain or maintain these
approvals could adversely affect our revenue or the number of our members, or
could increase our costs. A significant portion of our revenues relate to
federal, state and local government health care coverage programs. These types
of programs, such as the federal Medicare program and the federal and state
Medicaid programs, generally are subject to frequent change, including changes
that may reduce the number of persons enrolled or eligible, reduce the amount of
reimbursement or payment levels, or may reduce or increase our administrative or
health care costs under such programs. Such changes have adversely affected our
results and willingness to participate in such programs in the past and may also
do so in the future.
 
    The Company also is subject to various governmental reviews, audits and
investigations. Such oversight could result in the loss of licensure or the
right to participate in certain programs, or the imposition of fines, penalties
and other sanctions. In addition, disclosure of any adverse investigation or
audit results or sanctions could damage our reputation in various markets and
make it more difficult for us to sell our products and services. The National
Association of Insurance Commissioners (the "NAIC") is expected to adopt rules
which, if implemented by the states, will require certain capitalization levels
for health care coverage provided by insurance companies, HMOs and other risk
bearing health care entities. The requirements would take the form of risk-based
capital rules. Currently, similar risk-based capital rules apply generally to
insurance companies. Depending on the nature and extent of the new minimum
capitalization requirements ultimately implemented, there could be an increase
in the capital required for certain of our subsidiaries and there may be some
potential for disparate treatment of competing products. Federal solvency
regulation of companies providing Medicare-related benefit programs may also be
applied.
 
    PROVIDER RELATIONS.  One of the significant techniques we use to manage
health care costs and utilization and monitor the quality of care being
delivered is contracting with physicians, hospitals and other providers. Because
our health plans are geographically diverse and most of those health plans
contract with a large number of providers, we currently believe our exposure to
provider relations issues is limited. In any particular market, however,
providers could refuse to contract, demand higher payments, or take other
actions that could result in higher health care costs, less desirable products
for customer and members, or difficulty meeting regulatory or accreditation
requirements. In some markets, certain providers, particularly hospitals,
physician/hospital organizations or multi-specialty physician groups, may have
significant market positions or near monopolies. If these providers refuse to
contract with us, use their market position to negotiate favorable contracts, or
place us at a competitive disadvantage those activities could adversely affect
our ability to market products or to be profitable in those areas.
 
    LITIGATION AND INSURANCE.  We may be a party to a variety of legal actions
that affect any business, such as employment and employment
discrimination-related suits, employee benefit claims, breach of contract
actions, tort claims, shareholder suits, including securities fraud, and
intellectual property related litigation. In addition, because of the nature of
our business, we are subject to a variety of legal actions relating to our
business operations. These could include: claims relating to the denial of
health care benefits; medical malpractice actions; provider disputes over
compensation and termination of provider contracts; disputes related to
self-funded business, including actions alleging claim administration errors and
the failure to disclose network rate discounts and other fee and rebate
arrangements; disputes over copayment
 
                                       14
<PAGE>
calculations; and claims relating to customer audits and contract performance.
Recent court decisions and legislative activity may increase our exposure for
any of these types of claims. In some cases, substantial non-economic or
punitive damages may be sought. We currently have insurance coverage for some of
these potential liabilities. Other potential liabilities may not be covered by
insurance, insurers may dispute coverage, or the amount of insurance may not be
enough to cover the damages awarded. In addition, certain types of damages, such
as punitive damages, may not be covered by insurance and insurance coverage for
all or certain forms of liability may become unavailable or prohibitively
expensive in the future.
 
    INFORMATION SYSTEMS.  Our business depends significantly on effective
information systems, and we have many different information systems for its
various businesses. Our information systems require an ongoing commitment of
resources to maintain and enhance existing systems and develop new systems in
order to keep pace with continuing changes in information processing technology,
evolving industry standards, and changing customer preferences. In addition, we
may from time to time obtain significant portions of our systems-related or
other services or facilities from independent third parties, which may make our
operations vulnerable to such third parties' failure to perform adequately. As a
result of our acquisition activities, we have acquired additional systems and
have been taking steps to reduce the number of systems and have upgraded and
expanded our information systems capabilities. Failure to maintain effective and
efficient information systems could cause loss of existing customers, difficulty
in attracting new customers, customer and provider disputes, regulatory
problems, increases in administrative expenses or other adverse consequences.
 
    THE YEAR 2000.  We are in the process of modifying our computer systems to
accommodate the Year 2000. We currently expect to complete this modification
enough in advance of the Year 2000 to avoid adverse impacts on our operations.
We are expensing the costs incurred to make these modifications. Our operations
could be adversely affected if we were unable to complete our Year 2000
modifications in a timely manner or if other companies with which we do business
fail to complete their Year 2000 modifications in a timely manner.
 
    ADMINISTRATIVE AND MANAGEMENT.  Efficient and cost-effective administration
of our operations is essential to our profitability and competitive positioning.
While we attempt to effectively manage such expenses, staff-related and other
administrative expenses may rise from time to time due to business or product
start-ups or expansions, growth or changes in business, acquisitions, regulatory
requirements or other reasons. These expense increases are not clearly
predictable and may adversely affect results. We believe we currently have an
experienced, capable management and technical staff. The market for management
and technical personnel, including information systems professionals, in the
health care industry is very competitive. Loss of certain managers or a number
of such managers or technical staff could adversely affect our ability to
administer and manage our business.
 
    MARKETING.  We market our products and services through both employed sales
people and independent sales agents. Although we have many sales employees and
agents, the departure of certain key sales employees or agents or a large subset
of such individuals could impair our ability to retain existing customers and
members. In addition, certain of our customers or potential customers consider
rating, accreditation or certification of the Company by various private or
governmental bodies or rating agencies necessary or important. Certain of our
health plans or other business units may not have obtained or maintained, or may
not desire or be able to obtain or maintain, such rating accreditation or
certification, which could adversely affect our ability to obtain or retain
business with these customers.
 
    ACQUISITIONS AND DISPOSITIONS.  The Company has made several large
acquisitions in recent years and has an active ongoing acquisition and
disposition program under which it may engage in transactions involving the
acquisition or disposition of assets, products or businesses, some or all of
which may be material. These acquisitions may entail certain risks and
uncertainties and may affect ongoing business operations because of unknown
liabilities, unforeseen administrative needs or increased efforts to integrate
the acquired operations. Failure to identify liabilities, anticipate additional
administrative needs or
 
                                       15
<PAGE>
effectively integrate acquired operations could result in reduced revenues,
increased administrative and other costs, or customer confusion or
dissatisfaction.
 
    DATA AND PROPRIETARY INFORMATION.  Many of the products that are part of our
knowledge and information services business depend significantly on the
integrity of the data on which they are based. If the information contained in
our databases were found or perceived to be inaccurate, or if such information
were generally perceived to be unreliable, commercial acceptance of our
database-related products would be adversely and materially affected.
Furthermore, the use by our knowledge and information-related business of
patient data is regulated at federal, state, and local levels. These laws and
rules are changed frequently by legislation or administrative interpretation.
These restrictions could adversely affect revenues from these products and, more
generally, affect our business, financial condition and results of operations.
 
    The success of our knowledge and information services business also depends
significantly on our ability to maintain proprietary rights to our products. We
rely on our agreements with customers, confidentiality agreements with
employees, and our trade secrets, copyrights and patents to protect our
proprietary rights. We cannot assure that these legal protections and
precautions will prevent misappropriation of our proprietary information. In
addition, substantial litigation regarding intellectual property rights exists
in the software industry, and we expect software products to be increasingly
subject to third-party infringement claims as the number of products and
competitors in this industry segment grows. Such litigation could have an
adverse affect on the ability of our knowledge and information-related business
to market and sell its products and on our business, financial condition and
results of operations.
 
    STOCK MARKET.  The market prices of the securities of the Company and
certain of the publicly-held companies in the industry in which we operate have
shown volatility and sensitivity in response to many factors, including general
market trends, public communications regarding managed care, legislative or
regulatory actions health care cost trends, pricing trends, competition,
earnings or membership reports of particular industry participants, and
acquisition activity. We cannot assure the level or stability of our share price
at any time, or the impact of the foregoing or any other factors may have on our
share price.

ITEM 2. PROPERTIES
 
    As of December 31, 1998, the Company leased approximately 1.72 million
aggregate square feet of space for its principal administrative offices in the
greater Minneapolis/St. Paul, Minnesota area and in Hartford, Connecticut.
Excluding these areas, as of December 31, 1998, the Company leased approximately
6.38 million aggregate square feet in the United States, and approximately
97,100 aggregate square
 
                                       17
<PAGE>
feet outside of the United States (including Puerto Rico). Such space
accommodates health plans, managed care services, specialty programs or
satellite administrative offices. The Company's leases expire at various dates
through May 31, 2026. As of December 31, 1998, the Company owned approximately
310,700 aggregate square feet of space for administrative offices in various
states and its staff model clinic operations in Florida.
 
ITEM 3. LEGAL PROCEEDINGS
 
    Because of the nature of its business, United is subject to suits relating
to the failure to provide or pay for health care or other benefits, poor
outcomes for care delivered or arranged under United's programs, nonacceptance
or termination of providers, failure to return withheld amounts from provider
compensation, failure of a self-funded plan serviced by United to pay benefits,
improper copayment calculations and other forms of legal actions. Some of these
suits may include claims for substantial non-economic or punitive damages.
United does not believe that any such actions, or any other types of actions,
currently threatened or pending will, individually or in the aggregate, have a
material adverse effect on United's financial position or results of operations.
However, the likelihood or outcome of current or future suits cannot be
accurately predicted, and they could adversely affect United's financial
results.
 
    Six suits assert claims under the United States securities laws against
United and certain of its current and former officers and directors. The
plaintiffs are stockholders of United who purport to sue on behalf of a class of
purchasers of common shares of United during the period February 12, 1998
through August 5, 1998 (the "Class Period"). Each complaint was filed in the
United States District Court for the District of Minnesota. Each of the six
actions claims violations of Sections 10(b) and 20(a) of the Securities Exchange
Act and SEC Rule 10b-5. In substance, the complaints allege that United made
materially false or misleading statements about the profitability and
performance of the Company's Medicare business during the Class Period. Two of
the complaints also allege that the Company made materially false statements
about its medical costs and the expenses related to the Company's realignment.
The complaints also allege that the statements were made with the intention of
deceiving members of the investing public and with the intention that the price
of United shares would rise, making it possible for insiders at the Company to
profit by selling shares at a time when they knew the Company's true financial
condition, but the investing public did not. The complaints allege that once the
Company's true financial condition was revealed on August 6, 1998, the price of
United common shares fell from a closing price of $52 7/8 on August 5, 1998, to
a closing price of $37 7/8 on August 6, 1998. The complaints seek compensatory
damages in unspecified amounts.
 
    On January 19, 1999, we received a consolidated amended complaint (IN RE
UNITED HEALTHCARE CORPORATION SECURITIES LITIGATION, No. 98-1888 in the United
States District Court for the District of Minnesota) for the six suits which
essentially restates the allegations made in the earlier complaints.
 
    On March 22, 1999, two actions were filed in the United States District
Court for the District of Minnesota by two pension funds against United, certain
current and former officers and directors, and other individuals yet to be
identified. The pension funds wish to "opt-out" of the aforementioned purported
class action suits. These individual actions essentially restate the allegations
made in the purported class actions and claim violations of Sections 10(b),
18(a) and 20 of the Securities Exchange Act. In addition, both actions assert a
claim of negligent misrepresentation and securities claims under state law. In
the aggregate, the plaintiff pension funds seek compensatory damages totaling
approximately $12.1 million.
 
    The defendants intend to defend these actions vigorously.

million after tax, or $0.13 diluted net earnings per common share), 1994 
earnings before extraordinary gain would have been $310 million or $1.77 
diluted net earnings per common share.

(5) In May 1994, the Company sold Diversified Pharmaceutical Services, Inc. for 
$2.3 billion in cash and recognized an extraordinary gain after transaction 
costs and income tax effects of $1.4 billion, or $7.86 diluted net earnings per 
common share.

(6) During 1998, we issued notes and commercial paper aggregating $708 million, 
which remained outstanding at December 31, 1998.

RESULTS OF OPERATIONS

1998 FINANCIAL PERFORMANCE HIGHLIGHTS

1998 was an important year of both challenges and successes for UnitedHealth 
Group.

- -  Excluding the effects of the unusual or nonrecurring events and transactions 
described below, we achieved record profits. Underlying earnings from 
operations, net earnings applicable to common shareholders, and diluted net 
earnings per common share were $858 million, $509 million and $2.62 per share, 
respectively, representing increases over 1997 of 16%, 18%, and 16%, 
respectively.

- -  We achieved record revenues of $17.4 billion, a 47% increase over 1997. This 
growth was driven primarily by same-store enrollment growth in our 
UnitedHealthcare business and from successful implementation of our $3.5 
billion Medicare supplement insurance program with the AARP.

- -  Record cash flows of more than $1.0 billion were generated from operating 
activities, a 57% increase over 1997.

- -  We completed several financing initiatives to achieve a more efficient 
capital structure, including the redemption of our $500 million convertible 
preferred stock and the repurchase of 11.3 million shares of our common stock.

- -  We embarked on a major realignment of our operations into independent but 
strategically linked businesses, each focused on performance, growth and 
shareholder value. As a result of our evaluation of each business's strategic 
fit and contributions, analysis of our profitability in certain markets, and 
the adequacy of our medical costs payable estimates, we took actions that 
resulted in special operating charges of $900 million.

1998 OPERATING RESULTS OVERVIEW

(1) Excluding the effects of $725 million of operational realignment and other 
charges, $175 million of charges related to contract losses associated with 
certain Medicare markets and other increases to commercial and Medicare medical 
costs payable estimates, and the $20 million convertible preferred stock 
redemption premium, earnings from operations, net earnings applicable to common 
shareholders, and diluted net earnings per common share would have been $858 
million, $509 million, and $2.62 per share, respectively.

(2) Excluding the effects of a $45 million provision for future losses on two 
large multi-year contracts and $15 million of merger costs associated with the 
acquisition of HealthWise of America, Inc., earnings from operations, net 
earnings applicable to common shareholders, and diluted net earnings per common 
share would have been $641 million, $392 million, and $1.96 per share, 
respectively.

(3)Includes $175 million of contract losses associated with certain Medicare 
markets and other increases to commercial and Medicare medical costs payable 
estimates. The company's ratio of medical costs to premium revenues for the 
year ended December 31, 1998, would have been 86.0% without these charges.

In 1998, we reported a net loss applicable to common shareholders of $214 
million, or $1.12 diluted net loss per common share. However, these results 
include certain large or unusual events and transactions as described below:

- -  In conjunction with our realignment and other initiatives, we recorded $725 
million of charges to operations during the second quarter of 1998. The charges 
included $451 million of asset impairments and $274 million of estimated future 
costs associated with our initiatives, such as employee terminations; disposing 
of or discontinuing business units, product lines and contracts; and 
consolidating certain processing operations and associated real estate 
obligations. Although our realignment initiatives and the associated 
nonrecurring charges caused us to report a net loss for 1998, these actions 
position us to make long-term fundamental process and performance improvements.

- -  Our second quarter 1998 medical costs include $120 million related to 
contract losses and other increases to medical costs payable estimates in 
UnitedHealthcare's Medicare markets and $55 million related to increases to 
medical costs payable estimates associated with increased commercial medical 
costs in certain health plans.

- -  In conjunction with the redemption of our $500 million convertible preferred 
stock, we paid a $20 million redemption premium. This premium is added to 
1998's net loss to arrive at net loss applicable to common shareholders.

         Excluding the effects of the events and transactions described above, 
1998 underlying earnings from operations and diluted net earnings per common 
share were $858 million and $2.62 per share, respectively, representing 
increases of 16% over earnings from operations of $742 million and diluted net 
earnings per common share of $2.26 in 1997. These increases were primarily 
driven by improved margins in the commercial product offerings of our 
UnitedHealthcare business and successful integration and management of our 
services provided to the AARP, which began on January 1, 1998.

         The discussion that follows provides a more detailed analysis of our 
1998, 1997 and 1996 operating results.

1998 RESULTS COMPARED TO 1997 RESULTS

REVENUES AND ENROLLMENT

1998 was a record year for UnitedHealth Group, with consolidated revenues of 
$17.4 billion, an increase of $5.6 billion, or 47%, over 1997. Our revenue 
growth was primarily derived from successful implementation of our $3.5 
billion Medicare supplement insurance program with the AARP and same-store 
enrollment growth in our UnitedHealthcare business. On a year-over-year 
same-store basis, UnitedHealthcare's total revenues increased by $1.7 
billion, or 16%, over 1997.

     The following table summarizes enrollment in all of our product 
offerings as of December 31:

Administrators, Inc. on June 30, 1997.

Our revenues are comprised of: 1) premium revenues associated with our 
risk-based products (those where we assume financial responsibility for 
health care costs); 2) management services and fees associated with

</TABLE>
NM - Not Meaningful

     Consolidated premium revenues in 1998 totaled $15.5 billion, an increase 
of $5.4 billion, or 53%, compared to 1997. On January 1, 1998, our Ovations 
business began delivering Medicare supplement insurance and other medical 
insurance coverage to approximately 4 million AARP members. Premium revenues 
from our portion of the AARP insurance offerings during 1998 were $3.5 
billion.

     Excluding the AARP business, 1998 consolidated premium revenues totaled 
$12.0 billion, an increase of 19% over 1997. This increase is primarily the 
result of growth in our UnitedHealthcare business. On a year-over-year 
same-store basis, UnitedHealthcare's premium revenues increased $1.7 billion, 
or 18%, during 1998. The increase reflects same-store commercial health plan 
enrollment growth of 10% and average year-over-year premium yield increases 
on renewing commercial health plan groups of approximately 5% to 6%.

     Growth in UnitedHealthcare's Medicare programs also contributed to the 
increase in premium revenues, with same-store growth of 33% in Medicare 
enrollment. Significant growth in Medicare enrollment affects year-over-year 
comparability. The Medicare product generally has per member premium rates 
three times to four times higher than average commercial premium rates 
because Medicare members typically use proportionately more medical care 
services. On a year-over-year same-

                                    II-4

<PAGE>

store basis, UnitedHealthcare's commercial health plan and Medicare products 
accounted for $1.8 billion of premium revenue growth during 1998.

     The increase in UnitedHealthcare's commercial health plan and Medicare 
product premium revenues was partially offset by a $240 million decrease from 
other network-based and indemnity products. We expect enrollment in 
UnitedHealthcare's other network-based and indemnity products will continue 
to decline through 1999. To the extent possible, we will convert these 
enrollees to UnitedHealthcare's commercial health plan products.

MANAGEMENT SERVICES AND FEE REVENUES

Management services and fee revenues during 1998 totaled $1.6 billion, 
representing an increase of approximately $160 million over 1997. The 
increase is primarily the result of acquisitions by Ingenix during 1997 and 
1998. Additionally, our Specialized Care Services business -- most notably 
United Behavioral Health and Optum,-Registered Trademark- our telephone- and 
Internet-based health information and services business -- continues to 
increase the number of individuals it serves.

INVESTMENT AND OTHER INCOME

Investment and other income increased to $249 million in 1998 from $231 million
in 1997. The increase of $18 million is primarily attributable to an increase in
average cash and investments from $3.6 billion in 1997 to $4.1 billion in 1998.
Net capital gains were $26 million in both 1998 and 1997.

MEDICAL COSTS

The combination of our pricing strategy and medical management efforts is
reflected in the medical care ratio (medical costs as a percentage of premium
revenues). The following table summarizes our medical care ratio by product line
for the years ended December 31:

(1) Includes commercial health plan, other network-based and indemnity products.

     Our consolidated medical care ratio increased to 87.2% in 1998 from 
84.3% in 1997. The year-over-year increase includes the effects of the AARP 
business on our medical care ratio. We experience a medical care ratio of 
approximately 92% related to our portion of the AARP insurance offerings, 
which we began delivering on January 1, 1998. Excluding the AARP business, on 
a year-over-year basis, the medical care ratio increased to 85.8%.

     The increase in the 1998 medical care ratio is primarily attributable to 
average Medicare premium rate increases of 2.5% that were more than offset by 
increased medical utilization, reflected mostly in hospital costs. In 13 of 
our 24 Medicare markets, representing half of our annual Medicare premiums of 
$2.4 billion, we incurred contract losses of $111 million. Six of these 13 
markets are generally newer markets where we have been unable to achieve the 
scale of operations necessary to achieve profitability. In numerous counties 
in the other seven markets, we experienced high medical costs which exceeded 
the fixed Medicare premiums that increased only 2.5% on average.

     We are addressing our Medicare medical care ratio by altering benefit 
designs, recontracting with providers, and aggressively increasing both 
contemporaneous and retrospective claim management activities. We also are 
continuing to evaluate the markets we serve and products we offer. In 
addition, we will curtail activities or exit markets where we believe near 
term prospects are unacceptable.

     To that end, in October 1998, we announced our decision to withdraw 
Medicare product offerings from 86 of the 206 counties we then served. The 
decision, effective January 1, 1999, affected approximately 60,000, or 13%, 
of our Medicare members. We will continue to offer Medicare products in 
strong and economically viable markets. Annual revenues for 1998 from 
Medicare counties we exited were approximately $225 million.

     Despite increasing commercial medical cost trends in certain health plan 
markets, UnitedHealthcare's overall commercial medical care ratio improved 
slightly to 85.3% in 1998 from 85.7% in 1997.

     Commercial health plan premium rates are established based on 
anticipated health care costs. During 1998, commercial premium yield 
increases averaging 5% to 6% minimally exceeded medical cost trends of 4% to 
5%. Looking to 1999, we expect average medical cost increases to remain 
stable in the 4% to 5% range, and we also expect that our medical care ratio 
will improve as a result of premium yield increases on new and renewal 
commercial business averaging 7% to 8%.

OPERATING EXPENSES

Selling, general and administrative expenses as a percent of total revenues 
(the SG&A ratio) decreased from 20.0% in 1997 to 17.1% in 1998. The 
improvement in the year-over-year SG&A ratio principally reflects the 
operating leverage we gained with the addition of the AARP business and 
planned cost reductions we have achieved to date from our realignment 
initiatives. On an absolute dollar basis, selling, general and administrative 
costs increased by $600 million, or 25%, over 1997. This increase primarily 
reflects the additional infrastructure needed to support the $5.4 billion, or 
53%, increase in premium-based business.

     Depreciation and amortization was $185 million in 1998, and $146
million in 1997. This increase resulted from a combination of higher levels of
capital expenditures to support business growth and amortization of goodwill and
other intangible assets related to recent acquisitions.

     The $451 million of asset impairments recorded in the second quarter of 
1998 will reduce depreciation and amortization by approximately $15 million 
annually. This decrease will be more than offset in 1999 by increased 
depreciation and amortization related to capital expenditures and intangible 
assets acquired in acquisitions during 1998.

OPERATIONAL REALIGNMENT AND OTHER CHARGES
In conjunction with our operational realignment, we developed and, in the second
quarter of 1998, approved a comprehensive plan (the Plan) to implement our
operational realignment. We recognized corresponding charges to operations of
$725 million, which reflect the estimated costs we will incur under the Plan.
The charges included costs associated with asset impairments; employee
terminations; disposing of or discontinuing business units, product lines and
contracts; and consolidating and eliminating certain processing operations and
associated real estate obligations. These activities will result in a net
reduction of more than 4,000 positions, affecting 6,000 people in various
locations. Through December 31, 1998, we have eliminated approximately 2,000
positions pursuant to the Plan.

         Businesses we intend to dispose of include our managed workers'
compensation business, and medical and behavioral health provider clinics.
Markets where we plan to curtail or make changes to our operating presence
include our small group health insurance business and three health plan markets
that are in non-strategic locations.

         Our original provision for operational realignment and other charges 
was developed based on management's best judgment and estimates at that time. 
As we began to execute the Plan, we adjusted certain estimates based on more 
current information related to the amounts to be paid for severance and lease 
cancellation fees. In addition, based on continuing negotiations related to 
business dispositions, our original estimates for asset impairments and 
business disposition costs were revised.  In total, our Operational 
Realignment and Other Charges did not change.

         We have included in asset impairments the write off of $68 million 
of purchased in-process research and development associated with the 
acquisition of Medicode, Inc. The in-process projects were focused on the 
continued development and evolution of next generation medical databases and 
software solutions including clinical editing software, benchmarking databases 
and technologies. These technologies upon completion will enable both 
healthcare payers and providers to use the same data generated in the 
treatment documentation process to then be used in the financial transaction 
process, which involves provider compensation, care utilization review, trend 
analysis and management reporting. As of the date of acquisition, Medicode 
had invested $8.5 million in the in-process projects identified above. We 
estimate that it will be necessary to dedicate approximately $2.2 million 
over the next sixteen months in order to successfully complete these projects.

Details of the asset impairments are as follows (in millions):

         We believe the aggregate reduction in our overall cost structure from
our realignment and other cost reduction activities will approximate $300
million annually by the end of the year 2000. We expect to realize approximately
$75 million of these reductions in 1999.

         The operational realignment charges do not cover certain aspects of 
the Plan, including new information systems, data conversions, process 
re-engineering and employee relocation and training. These costs will be 
charged to expense as incurred or capitalized, as appropriate.


1997 RESULTS COMPARED TO 1996 RESULTS

PREMIUM REVENUES
During 1997, consolidated premium revenues totaled $10.1 billion, representing
an increase of $1.6 billion, or 19%, compared to 1996. Excluding the effects of
acquisitions, premium revenues in 1997 increased by 17% over 1996.

         The increase in premium revenues in 1997 was primarily due to growth in
year-over-year same-store commercial health plan revenues of $1.5 billion, or
25%. The increase reflected same-store commercial health plan enrollment growth
of 13% and

                                    II-6

<PAGE>

average year-over-year premium rate increases on renewing commercial groups 
of approximately 5%. Growth in our Medicare programs also contributed to the 
increase in premium revenues, with a year-over-year same-store increase of 
53% in Medicare enrollment.

         The 1997 year-over-year increase in premium revenues from commercial
and Medicare products was partially offset by a $220 million decrease from
non-network-based indemnity products. Nearly $60 million of this decrease
resulted because we discontinued our relationship with a broker who sold and
administered small group indemnity business on our behalf, which led to the loss
of 30,000 indemnity members effective July 1, 1997. The remaining decrease was
from declining enrollment in these products, which is attributed to average rate
increases of 10% to 20% that started in 1996 and continued into 1997, as well as
other business factors.

MANAGEMENT SERVICES AND FEE REVENUES
Management services and fee revenues in 1997 totaled $1.4 billion, representing
an increase of $30 million, or 2%, over 1996. The increase resulted from
enrollment growth within managed health plans and an increase in individuals
served by our Specialized Care Services business. Offsetting these increases,
fee revenues from self-funded products decreased $15 million because of
declining enrollment in these products. In addition, the June 30, 1997, sale of
our subsidiary, United HealthCare Administrators, Inc., resulted in a $24
million decrease in these revenues in 1997 compared to 1996.

INVESTMENT AND OTHER INCOME
Investment and other income increased to $231 million in 1997 from $185 million
in 1996. The increase of $46 million is primarily attributable to an increase in
average cash and investments from $3.2 billion in 1996 to $3.6 billion in 1997.
Additionally, 1997 investment and other income included net capital gains of $26
million compared with $4 million in 1996.

MEDICAL COSTS
During 1997, the medical care ratio increased slightly from 84.0% in 1996
(before nonrecurring charges) to 84.3%. The 1997 increase in the medical care
ratio was the result of several factors: 

- - A few specific health plan markets had medical care ratios substantially 
higher than our other health plans in the aggregate. The reasons varied from 
plan to plan, but generally, medical cost controls and provider contracting 
initiatives were not being fully implemented and commercial premium yields 
were insufficient compared to corresponding medical costs. 

- - Several markets had recently introduced Medicare products, which had been 
well received and were growing rapidly. We generally experience higher 
medical care ratios during the early stage of Medicare product introductions. 

- - Medicaid premiums did not increase and, in fact, decreased in several 
markets.

OPERATING EXPENSES
During 1997, our SG&A ratio improved from 21.5% in 1996 to 20.0%. The
improvement in the 1997 SG&A ratio reflected ongoing operating efficiencies as
well as our diligence in managing operating expenses. On an absolute dollar
basis, selling, general and administrative costs increased $199 million in 1997,
or 9%, over 1996. This increase reflects the additional infrastructure needed to
support the $1.6 billion increase in premium-based business, as well as the
additional investment in new Medicare markets and increased support for our
growing Specialized Care Services businesses.

FINANCIAL CONDITION AND LIQUIDITY AS OF DECEMBER 31, 1998
During 1998, we generated more than $1.0 billion in cash from operating
activities. We continued to maintain a strong financial condition and liquidity
position, with cash and investments of $4.4 billion at December 31, 1998, an
increase of $400 million over December 31, 1997. Our long-term investments, $2.6
billion as of December 31, 1998, are classified as available for sale and are
periodically sold prior to their maturity date to fund working capital or for
other purposes.

         During 1998, we also took several actions to improve our capital
structure:

- - We redeemed $500 million of convertible preferred stock with a cumulative
dividend rate of 5.75% (a pre-tax effective rate of approximately 9.0%). The
redemption of the preferred shares was financed with $650 million of unsecured
notes payable at a weighted-average pre-tax effective interest rate of 6.0%,
thereby decreasing our financing cost for this $500 million by 34% in the first
year. The debt placement consisted of $400 million in unsecured notes due
December 1999, with an interest rate of 5.65%, and $250 million in unsecured
notes due December 2003, with an interest rate of 6.65%. 

- - We repurchased 11.3 million shares of our common stock for an aggregate 
cost of $436 million, an average cost of approximately $40 per share. Under 
our stock repurchase program, we may purchase up to 18.7 million shares of 
our outstanding common stock. Purchases may be made from time to time at 
prevailing prices, subject to certain restrictions relating to volume, 
pricing and timing. 

- - We established a $600 million commercial paper program, which provides 
increased flexibility in managing our capital structure. At December 31, 
1998, there were $59 million in commercial paper borrowings outstanding at an 
average interest rate of 5.3%.

         In support of our commercial paper program, we entered into a $600
million credit arrangement with a group of banks. The agreement is comprised of
a $300 million five-year revolving credit facility and a $300 million 364-day
credit facility. No borrowings were outstanding under the credit facilities as
of December 31, 1998.

                                    II-7

<PAGE>

- - In January 1998, we filed a shelf registration statement with the Securities
and Exchange Commission (SEC) to sell up to $200 million of debt securities and
preferred or common shares. The shelf filing registered the securities and
allows us to sell them from time to time in the event we need financing.
Proceeds from sales of these securities may be used for a variety of general
corporate purposes, including working capital, securities repurchases and
acquisitions. In October 1998, we filed another shelf registration statement to
sell up to $1.05 billion of debt securities, preferred stock, common stock,
depository shares, warrants and trust preferred securities. These securities may
not be sold until the SEC declares the registration statement effective.

         Cash generated from operating activities and proceeds received from our
1998 financing activities were used to redeem outstanding preferred stock,
repurchase common stock, and for other general corporate purposes, including
acquisitions. We expect our available cash and investment resources, operating
cash flows, and financing capability to be sufficient to meet our current
operating requirements and other corporate development initiatives.

         As further described under "Regulatory Capital and Dividend
Restrictions," many of our subsidiaries are subject to various government
regulations. After taking into account these regulations, approximately $500
million of our $4.4 billion of cash and investments at December 31, 1998, was
available for general corporate use, including working capital needs.

         The Company's debt arrangements and credit facilities contain various
covenants, the most restrictive of which place limitations on secured and
unsecured borrowings and require the Company to exceed minimum interest coverage
levels. At December 31, 1998, we were well within the requirements of all debt
covenants.

         In the second quarter of 1998, we recognized special charges to
operations of $725 million associated with the implementation of our operational
realignment plan. We believe our after-tax cash outlay associated with these
charges will be in the range of $75 million to $100 million over the next 12
months.

         Currently, we do not have any other material definitive commitments
that require cash resources; however, we continually evaluate opportunities to
expand our operations. This includes internal development of new products and
programs and may include acquisitions.

GOVERNMENT REGULATION
Our primary business, offering health care coverage and health care management
services, is heavily regulated at the federal and state levels. We strive to
comply in all respects with applicable regulations and may be required to make
changes from time to time in our services, products, marketing methods or
organizational or capital structure.

         Regulatory agencies generally have broad discretion to issue
regulations and interpret and enforce laws and rules. Changes in applicable laws
and regulations are continually being considered, and the interpretation of
existing laws and rules also may change from time to time. These changes could
affect our operations and financial results.

         Certain proposed changes in Medicare and Medicaid programs may improve
opportunities to enroll people under products developed for these populations.
Other proposed changes could limit available reimbursement and increase
competition in those programs, with adverse effects on our financial results.
Also, it could be more difficult for us to control costs if federal and state
bodies continue to consider and enact significant and onerous managed care laws
and regulations. Among the legislative proposals are proposals that could expand
health plan liability or increase medical expenses.

         The Health Insurance Portability and Accountability Act of 1996 (HIPAA)
may represent the most significant federal reform of employee benefit law since
the enactment of the Employee Retirement Income Security Act (ERISA) in 1974.
Significant provisions of HIPAA include guaranteeing the availability of health
insurance for certain employees, limiting the use of preexisting condition
exclusions, prohibiting discrimination on the basis of health status, and making
it easier to continue coverage in cases where a person is terminated or changes
employers. Under HIPAA and other similar state laws, medical cost control
through amended provider contracts and improved preventive and chronic care
management may become more important. We believe our experience in these areas
will allow us to compete effectively.

         A comprehensive set of claims regulations has been proposed by the
United States Department of Labor (DOL) that could have a significant impact on
the Company. These regulations are applicable to employee benefit plans subject
to ERISA. In addition to various other requirements, the regulations would
create new time frames for processing claims and giving notification of
incomplete claims, would impose certain notification requirements following a
claim determination, and would impose certain post-appeal disclosure obligations
on the Company's insured and self-funded business. The DOL has solicited public
comment on the proposals, and the regulations, if adopted, could vary
significantly from the proposals.

         Health care fraud and abuse has become a top priority for the nation's
law enforcement entities, which have focused on participants in federal
government health care programs such as Medicare, Medicaid and the Federal
Employees Health Benefits Program (FEHBP). We participate extensively in these
programs.

         We also are subject to governmental investigations and enforcement
actions. Included are actions relating to ERISA, which regulates insured and
self-insured health coverage plans offered by employers; the FEHBP; Medicare and
Medicaid; federal and state fraud and abuse laws; and laws relating to care
management and health care delivery. Government actions could result in
assessment of damages, civil or criminal fines or penalties, or other sanctions,
including exclusion from participation in government programs. We currently are
involved in various government investigations and audits, but we do not believe
the results will have a material adverse effect on our financial position or
results of operations.

REGULATORY CAPITAL AND
DIVIDEND RESTRICTIONS
The Company's operations are conducted through United HealthCare Corporation,
its wholly-owned subsidiary United HealthCare Services, Inc. and their
respective subsidiaries, which consist principally of Health Maintenance
Organizations (HMOs) and insurance companies. HMOs and insurance companies are
subject to state regulations that, among other things, may require the
maintenance of minimum levels of statutory capital, as defined by each state,
and restrict the timing and amount of dividends and other distributions that may
be paid to their respective parent companies. Generally, the amount of dividend
distributions that may be paid by regulated insurance and HMO companies, without
prior approval by state regulatory authorities, is limited based on the entity's
level of statutory net income and statutory capital and surplus.

         As of December 31, 1998, the Company's regulated subsidiaries had
aggregate statutory capital and surplus of approximately $1.4 billion, compared
with their aggregate minimum statutory capital and surplus requirements of $390
million. The amount of dividends that may be paid to the Company or United
HealthCare Services, Inc., by their insurance and HMO subsidiaries at December
31, 1998, without prior approval by state regulatory authorities, is limited to
approximately $120 million. There are no such restrictions on distributions from
United HealthCare Services, Inc. to the Company or on distributions from the
Company to its shareholders.

         The National Association of Insurance Commissioners has adopted rules
which, to the extent that they are implemented by the states, will set new
minimum capitalization requirements for insurance companies, HMOs and other
entities bearing risk for health care coverage. The requirements take the form
of risk-based capital rules. The change in rules for insurance companies was
effective December 31, 1998. The new HMO rules are subject to state-by-state
adoption, but few states had adopted the rules as of December 31, 1998. The HMO
rules, if adopted by the states in their proposed form, would significantly
increase the capital required for certain of our subsidiaries. However, we
believe we can redeploy capital among our regulated entities to minimize the
need for incremental capital investment of general corporate financial resources
into regulated subsidiaries. As such, we do not anticipate a significant impact
on our aggregate capital or investments in regulated subsidiaries.

CONCENTRATIONS OF CREDIT RISK
Investments in financial instruments such as marketable securities and
commercial premiums receivable may subject UnitedHealth Group to concentrations
of credit risk. Our investments in marketable securities are managed by
professional investment managers within an investment policy authorized by the
board of directors. This policy limits the amounts that may be invested in any
one issuer. Concentrations of credit risk with respect to commercial premiums
receivable are limited to the large number of employer groups that comprise our
customer base. As of December 31, 1998, there were no significant concentrations
of credit risk.


QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
Since the date of the Company's quarterly report filed on Form 10-Q for the
quarter ended September 30, 1998, no material changes have occurred in the
Company's exposure to market risk associated with our investments in market
risk-sensitive financial instruments. We do not believe that our risk of a loss
in future earnings or a decline in fair values or cash flow attributable to such
investments is material.

INFLATION
Although the general rate of inflation has remained relatively stable and health
care cost inflation has stabilized in recent years, the national health care
cost inflation rate still exceeds the general inflation rate. We use various
strategies to mitigate the negative effects of health care cost inflation,
including setting commercial premiums based on anticipated health care costs,
risk-sharing arrangements with various health care providers, and other health
care cost containment measures. Specifically, health plans try to control
medical and hospital costs through contracts with independent providers of
health care services. Through these contracted care providers, our health plans
emphasize preventive health care and appropriate use of specialty and hospital
services.

         While we currently believe our strategies to mitigate health care cost
inflation will continue to be successful, competitive pressures, new health care
product introductions, demands from health care providers and customers,
applicable regulations, or other factors may affect our ability to control the
impact of health care cost increases. In addition, certain non-network-based
products do not have health care cost containment measures similar to those in
place for network-based products. As a result, there is added health care cost
inflation risk with these products.

YEAR 2000 ACTIVITIES
Our business depends significantly on effective information systems, and we have
many different information systems for our various businesses. Our information
systems require ongoing enhancements to keep pace with the continuing changes in
information technology, evolving industry standards, and customer preferences.
We have been modifying our computer systems to accommodate the Year 2000. The
Year 2000 problem exists throughout the global marketplace, as many computer
systems and applications were developed to recognize the year as a two-digit
number, with the digits "00" being recognized as the year 1900.

         Starting in 1995, our formal Year 2000 Project Office began
implementing a remediation plan so that critical information systems
applications, end-user developed application tools, and business interfaces
remain intact and can function properly through the century change. We are on
schedule to complete, test and certify our Year 2000 remediation efforts by
September 30, 1999. A more detailed description and current status of our Year
2000 activities follows.

                                    II-9

TECHNICAL INFRASTRUCTURE

MAINFRAME TECHNOLOGY In conjunction with our two vendors that provide support
for our data center operations, we have completed, tested and certified 99% of
our remediation efforts for the hardware, operating system and supporting
software remediation efforts on our two primary mainframe computer systems. In
addition, we are in the process of reviewing some of our smaller mainframe
systems and making modifications as necessary. We expect to be 100% complete
with all mainframe hardware and software technology Year 2000 modifications by
March 31, 1999. We also have installed separate test environments (both
mainframe and distributed) to test our business applications in a simulated Year
2000 environment.

DESKTOP HARDWARE AND SOFTWARE We have inventoried all of our desktop hardware
and software-- more than 40,000 computing devices of multiple makes and models.
All noncompliant desktop hardware and software have been identified and are
being modified or replaced with compliant systems by September 30, 1999.

TELECOMMUNICATIONS We have inventoried all of our telecommunication systems--
more than 28,000 telecommunication devices, including traffic routers and phone
switches. We are using two outside vendors to assist us in modifying or
replacing noncompliant telecommunication systems. As of December 31, 1998, we
were approximately 75% Year 2000 compliant with our data and voice networks. We
expect all of our telecommunication networks and devices will be Year 2000
compliant by September 30, 1999.

BUSINESS APPLICATIONS

CRITICAL SOFTWARE APPLICATIONS We use 500 different software applications that
include more than 80 million lines of computer code. We have surveyed our
software applications and have identified systems that will not be used after
December 31, 1999, and systems that will be modified for Year 2000 compliance.
We have determined that 36% of our software applications will not be used after
December 31, 1999, due to conversions, consolidations and software replacements.
Of the remaining applications, over 90% have been made Year 2000 compliant,
tested and certified or are scheduled to be certified for compliance. The
balance of the applications are yet to be tested. We expect all critical Year
2000 software modifications to be completed by March 31, 1999, with further
testing and certification during the remainder of 1999.

END-USER DEVELOPED APPLICATIONS End-user developed applications are analysis 
tools that have been internally developed by individual employees or 
operating segments primarily running on personal computers or client servers. 
The Year 2000 Project Office has continuously communicated with all employees 
explaining the risks of noncompliant applications and provided tools and 
techniques to make them compliant. We have identified and are tracking and 
assessing Year 2000 compliance issues with respect to all potentially 
critical end-user applications.

OTHER YEAR 2000 MATTERS

NON-INFORMATION TECHNOLOGY SYSTEMS
We have approximately 300 owned or leased facilities throughout the world. We
have contacted all of our facility managers regarding Year 2000 compliance
issues. In addition, we have contracted with a real estate management company to
assist in our Year 2000 compliance efforts. All facilities are scheduled to be
Year 2000 compliant by September 1, 1999.

DEPENDENCE ON THIRD PARTIES

We use approximately 300,000 different medical providers and more than 92,000
vendors. Approximately 2,000 vendors have been identified as critical business
partners and suppliers. We are currently in communication with these critical
business partners to analyze their Year 2000 compliance efforts. We expect to
complete our analysis of critical vendor readiness and identify alternative
vendors, where necessary, by July 31, 1999. We will not be individually
contacting all of the 300,000 medical providers with whom we conduct business
regarding Year 2000 compliance issues. However, we will be testing and verifying
the electronic collection of data with our providers through our EDI (electronic
data interface) clearinghouse vendors.

COSTS OF YEAR 2000 COMPLIANCE

The projected costs of our Year 2000 compliance efforts and the date on which we
plan to complete the necessary Year 2000 remediation efforts are based on
management's best estimates, which were derived using various assumptions of
future events. However, there can be no guarantee that these estimates will be
achieved, and actual results could differ significantly from our current plans.
Specific factors that might cause significant differences include, but are not
limited to, the availability and cost of personnel trained in this area, the
ability to locate and correct the relevant computer codes, and the ability of
our significant vendors, providers, customers, and others with whom we conduct
business to identify and resolve their own Year 2000 issues.

         Costs associated with modifying internal use software for Year 2000
compliance are charged to expense as incurred. Purchases of hardware or software
that replace existing hardware or software that is not Year 2000 compliant are
capitalized and amortized over their useful lives. As of December 31, 1998, our
historical and projected costs to complete our Year 2000 remediation plan were
as follows (in millions):

BUSINESS RISKS OF NONCOMPLIANT SYSTEMS

Although we are committed to completing and testing our remediation plan well in
advance of the Year 2000, there are risks if we do not meet our objectives by
December 31, 1999. Operationally, the most severe risk is business interruption.
Specific examples of situations that could cause business interruption include,
but are not limited to: computer hardware or application software processing
errors or failures, facilities or infrastructure failures, or critical outside
providers, suppliers, or customers who may not be Year 2000 compliant. Depending
on the extent and duration of business interruption resulting from noncompliant
Year 2000 systems, such interruption may have a material adverse effect on our
results of operations, liquidity and financial condition.

CONTINGENCY PLANS

Each area of our Year 2000 compliance effort is currently developing 
contingency plans to mitigate the risk of failure, and to provide for a 
speedy recovery from possible failures associated with the century change. 
The contingency plans detail strategies to implement in 1999 to prepare for 
the century rollover, and actions to execute if problems emerge. The target 
date for completion of the initial contingency plans is April 1, 1999. 
Contingency plans will be final by July 31, 1999.

LEGAL MATTERS

Six suits assert claims under the U.S. securities laws against UnitedHealth
Group and certain of its current and former officers and directors. The
plaintiffs are shareholders of the Company who purport to sue on behalf of a
class of purchasers of the Company's common shares during the period February
12, 1998, through August 5, 1998 (the "Class Period"). Each complaint was filed
in the United States District Court for the District of Minnesota. Each of the
six actions claims violations of Sections 10(b) and 20(a) of the Securities
Exchange Act and SEC Rule 10b-5. In substance, the complaints allege that the
Company made materially false or misleading statements about the profitability
and performance of the Company's Medicare business during the Class Period. Two
of the complaints also allege that the Company made materially false statements
about its medical costs and the expenses related to its realignment. The
complaints also allege that the statements were made with the intention of
deceiving members of the investing public and with the intention that the price
of the Company's shares would rise, making it possible for insiders at the
Company to profit by selling shares at a time when they knew the Company's true
financial condition, but the investing public did not. The complaints allege
that once the Company's true financial condition was revealed on August 6, 1998,
the price of its common shares fell from a closing price of $52 7/8 per share on
August 5, 1998, to a closing price of $37 7/8 per share on August 6, 1998.
The complaints seek compensatory damages in unspecified amounts.

         On January 19, 1999, we received a consolidated amended complaint (In
re United HealthCare Corporation Securities Litigation, No. 98-1888 in the
United States District Court for the District of Minnesota) for the six suits,
which essentially restates the allegations made in the earlier complaints.

         On March 22, 1999, two actions were filed in the United States 
District Court for the District of Minnesota by two pension funds against 
United, certain current and former officers and directors, and other 
individuals yet to be identified. The pension funds wish to "opt-out" of 
the aforementioned purported class action suits. These individual actions 
essentially restate the allegations made in the purported class actions and 
claim violations of Sections 10(b), 18(a) and 20 of the Securities Exchange 
Act. In addition, both actions assert a claim of negligent misrepresentation 
and securities claims under state law. In the aggregate, the plaintiff 
pension funds seek compensatory damages totaling approximately $12.1 million.

         We intend to defend these actions vigorously.

         We are also involved in other legal actions that arise in the ordinary
course of business. Although we cannot predict the outcomes of legal actions, it
is our opinion that the resolution of all currently pending or threatened
actions, including the class action lawsuit described above, will not have an
adverse effect on our consolidated financial position or results of operations.

CAUTIONARY STATEMENT REGARDING
"FORWARD-LOOKING" STATEMENTS

The statements contained in this Management's Discussion and Analysis of
Financial Condition and Results of Operation, and other sections of this annual
report to shareholders, include forward-looking statements within the meaning of
the Private Securities Litigation Reform Act of 1995 (the "PSLRA"). When used
herein, the words or phrases "believes," "expects," "anticipates," "intends,"
"will likely result," "estimates," "projects" or similar expressions are
intended to identify such forward-looking statements. Any of these
forward-looking statements involve risks and uncertainties that may cause the
Company's actual results to differ materially from the results discussed in the
forward-looking statements. Statements that are not strictly historical are
"forward-looking" statements under the safe harbor provisions of the PSLRA.
Forward-looking statements involve known and unknown risks, which may cause
actual results and corporate developments to differ materially from those
expected. Factors that could cause results and developments to differ materially
from expectations include, without limitation, the effects of state and federal
regulations, the effects of acquisitions and divestitures, and other risks
described from time to time in each of UnitedHealth Group's SEC reports,
including quarterly reports on Form 10-Q, annual reports on Form 10-K, and
reports on Form 8-K.

ITEM 7A. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK
 
    Since the date of the Company's Quarterly Report filed on Form 10-Q for the
quarter ended September 30, 1998, no material changes have occurred in the
Company's exposure to market risk associated with the Company's investments in
market risk sensitive financial instruments. We do not believe that our risk of
a loss in future earnings or a decline in fair values or cash flow attributable
to such investments is material.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS UNITEDHEALTH GROUP

(1) DESCRIPTION OF BUSINESS

UnitedHealth Group ("the Company," "we," "us," "our") is a national leader in
offering health care coverage and related services to help people achieve
improved health and well-being through all stages of life. We provide a broad
spectrum of products and services and operate in all 50 states, the District of
Columbia and Puerto Rico, as well as internationally.

(2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION

We have prepared the consolidated financial statements in accordance with
generally accepted accounting principles and have included the accounts of
UnitedHealth Group and its subsidiaries. We have eliminated all significant
intersegment and intercompany accounts and transactions.

USE OF ESTIMATES

These financial statements include some amounts that are based on our best
estimates and judgments. The most significant estimates relate to medical costs
payable and other policy liabilities, intangible asset valuations and useful
lives, integration reserves relating to acquisitions, and liabilities and asset
impairments relating to our operational realignment activities. These estimates
may be adjusted as more current information becomes available, and any
adjustment could be significant.

REVENUE RECOGNITION

Premium revenues are recognized in the period enrolled members are entitled to
receive health care services. Premium payments received from our customers prior
to such period are recorded as unearned premiums. Management services and fee
revenues are recognized in the period the related services are performed.
Premium revenues related to Medicare and Medicaid programs as a percentage of
total premium revenues were 20% in 1998, 22% in 1997, and 19% in 1996.

MEDICAL COSTS AND MEDICAL COSTS PAYABLE

Medical costs include claims paid, claims adjudicated but not yet paid,
estimates for claims received but not yet adjudicated, and estimates for claims
incurred but not yet received.

         The estimates of medical costs and medical costs payable are 
developed using actuarial methods based upon historical data for payment 
patterns, cost trends, product mix, seasonality, utilization of health care 
services and other relevant factors including product changes. The estimates 
are subject to change as actuarial methods change or as underlying facts, 
upon which estimates are based, change. We did not change our actuarial 
methods during 1998, 1997 or 1996. The impact of any changes in estimates is 
included in the determination of earnings in the period of change. Management 
believes that the amount of medical costs payable is adequate to cover the 
Company's liability for unpaid claims as of December 31, 1998.

CASH, CASH EQUIVALENTS, AND INVESTMENTS

Cash and cash equivalents are highly liquid investments with an original
maturity of three months or less. The fair value of cash and cash equivalents
approximates their carrying value because of the short maturity of the
instruments. Investments with a maturity of less than one year are classified as
short-term.

         Investments held by trustees or agencies according to state regulatory
requirements are classified as held-to-maturity based on our ability and intent
to hold these investments to maturity. Such investments are reported at
amortized cost and are included in long-term investments. All other investments
are classified as available for sale and reported at fair value based on quoted
market prices and are classified as short-term or long-term depending on their
maturity term. Periodically, we sell investments classified as long-term prior
to their maturity to fund working capital or for other purposes.

         Unrealized gains and losses on investments available for sale are
excluded from earnings and reported as a separate component of shareholders'
equity, net of income tax effects. To calculate realized gains and losses on the
sale of investments available for sale, we use the specific cost of each
investment sold. We have no investments classified as trading securities.

ASSETS UNDER MANAGEMENT

Under our 10-year agreement with the AARP, we are administering certain aspects
of the AARP's insurance program that were transferred from the program's
previous carrier (see Note 7). Pursuant to our agreement with the AARP, the
associated assets are managed separately from our general investment portfolio
and are used to fund expenditures associated with the AARP program. The assets
are invested at our discretion, within certain investment guidelines approved by
the AARP. At December 31, 1998, the assets were invested in marketable debt
securities. Interest earnings and realized investment gains and losses on these
assets accrue to the AARP policyholders and, as such, are not included in our
determination of earnings. Assets under management are reported at their
amortized cost. Unrealized gains and losses are included in the reserve
stabilization fund associated with the AARP program (see Note 7). At December
31, 1998, the AARP investment portfolio included unrealized gains of $12
million.

OTHER POLICY LIABILITIES

Other policy liabilities principally relate to experience-rated indemnity
products and primarily include retrospective rate credit reserves and customer
balances.

         Retrospective rate credit reserves represent premiums we received in
excess of claims and expenses charged under eligible contracts. Reserves
established for closed policy years are based on actual experience, while
reserves for open years are based on estimates of premiums, claims and expenses
incurred.

         Customer balances consist principally of deposit accounts and reserves
that have accumulated under certain experience-rated contracts. At the
customer's option, these balances may be returned to the customer or may be used
to pay future premiums or claims under eligible contracts.

PROPERTY AND EQUIPMENT

Property and equipment is stated at cost. Depreciation is calculated using the
straight-line method over the estimated useful life of the respective assets,
ranging from three years to 30 years. The weighted-average useful life of
property and equipment at December 31, 1998, was approximately six years.

GOODWILL AND OTHER INTANGIBLE ASSETS

Goodwill represents the purchase price and transaction costs associated with
businesses we acquired in excess of the estimated fair value of the net assets
of these businesses. To the extent possible, a portion of the excess purchase
price and transaction costs is assigned to certain identifiable intangible
assets. Goodwill and other intangible assets are being amortized on a
straight-line basis over useful lives ranging from three years to 40 years, with
a weighted-average useful life of 34 years.

         The useful lives of goodwill and other intangible assets have been
assigned based on our best judgment. We periodically evaluate whether certain
circumstances may affect the estimated useful lives or the recoverability of the
unamortized balance of goodwill or other intangible assets.

         The most significant components of goodwill and other intangible 
assets are comprised of goodwill of $1.6 billion in 1998 and $1.2 billion in 
1997, and employer group contracts and supporting infrastructure, 
distribution networks, and institutional knowledge of $800 million in 1998 
and $900 million in 1997, net of accumulated amortization.

LONG-LIVED ASSETS

We review long-lived assets for events or changes in circumstances that would
indicate we may not recover their carrying value. We consider a number of
factors, including estimated future undiscounted cash flows associated with the
long-lived asset, to make this decision. We record assets held for sale at the
lower of their carrying amount or fair value, less any costs associated with the
final settlement.

INCOME TAXES

Deferred income tax assets and liabilities are recognized for the differences
between the financial and income tax reporting bases of assets and liabilities
based on enacted tax rates and laws. The deferred income tax provision or
benefit generally reflects the net change in deferred income tax assets and
liabilities during the year. The current income tax provision reflects the tax
consequences of revenues and expenses currently taxable or deductible on various
income tax returns for the year reported.

STOCK-BASED COMPENSATION

We use the intrinsic value method for determining stock-based compensation
expenses. Under the intrinsic value method, we do not recognize compensation
expense when the exercise price of an employee stock option equals or exceeds
the fair market value of the stock on the date the option is granted.
Information on what our stock-based compensation expenses would have been had we
calculated those expenses using the fair market values of granted stock options
is included in Note 12.

NET EARNINGS (LOSS) PER COMMON SHARE

Basic net earnings (loss) per common share is computed by dividing net earnings
(loss) applicable to common shareholders by the weighted-average number of
common shares outstanding during the period. Diluted net earnings (loss) per
common share is determined using the weighted-average number of common shares
outstanding during the period, adjusted for the dilutive effect of common stock
equivalents, consisting of shares which might be issued upon exercise of common
stock options. In periods where losses are reported, the weighted-average number
of common shares outstanding excludes common stock equivalents, since their
inclusion would be anti-dilutive.

COMPREHENSIVE INCOME

Comprehensive income and its components is reported in the Consolidated
Statements of Changes in Shareholders' equity. Comprehensive income is defined
as changes in the equity of our business excluding changes resulting from
investments by and distributions to our shareholders.

RECENTLY ISSUED ACCOUNTING STANDARD

In June 1998, a new standard on accounting for derivative financial instruments
and hedging activities was issued. This new standard will not materially affect
our financial results or disclosures based upon our current investment
portfolio.

(3) ACQUISITIONS

In October 1998, our UnitedHealthcare business acquired HealthPartners of 
Arizona, Inc. (HPA), with 509,000 members as of the acquisition date. We paid 
$235 million in cash in exchange for all outstanding shares of HPA. We 
accounted for the acquisition using the purchase method of accounting, which 
means the purchase price was allocated to assets and liabilities acquired 
based on their estimated fair values at the date of acquisition and only the 
post-acquisition results of HPA are included in our consolidated financial 
statements. The purchase price and costs associated with the acquisition 
exceeded the preliminary estimated fair value of net assets acquired by $223 
million, which has been assigned to goodwill. The pro forma effects of the 
HPA acquisition on our consolidated financial statements were not material.

         During 1998, our Ingenix business segment acquired Kern-McNeill 
International (KMI), a New Jersey-based contract research organization, and 
St. Anthony Publishing, Inc. (St. Anthony), a leader in the health care 
coding and reimbursement publications market. In the aggregate, we paid $188 
million in cash and assumed liabilities of $17 million in exchange for all of 
the common stock of KMI and St. Anthony. We accounted for these acquisitions 
using the purchase method of accounting. The purchase price and costs 
associated with these acquisitions exceeded the preliminary estimated fair 
value of net assets acquired by $205 million, which has preliminarily been 
assigned to identifiable intangible assets and goodwill. The pro forma 
effects of these acquisitions on our consolidated financial statements were 
not material.

         In December 1997, Ingenix acquired Medicode, Inc. (Medicode), a 
leading provider of health care information products. We issued 2.4 million 
shares of common stock and 507,000 common stock options with a total fair 
value of $127 million in exchange for all outstanding shares of Medicode. We 
accounted for the acquisition using the purchase method of accounting. The 
purchase price and costs associated with the acquisition exceeded the 
preliminary estimated fair value of net assets acquired by $123 million, 
which was preliminarily assigned to goodwill. During the second quarter of 
1998, the Company completed the valuation of the intangible assets acquired 
in the Medicode transaction. Pursuant to the valuation, we expensed $68 
million of the excess purchase price representing purchased in-process 
technology that previously had been assigned to goodwill. In management's 
judgment, this amount reflects the amount we would reasonably expect to pay 
an unrelated party for each project included in the technology. The value of 
in-process research and development of $68 million represented approximately 
48% of the purchase price and was determined by estimating the costs to 
develop the purchased technology into commercially viable products, then 
estimating the resulting net cash flows from each project that was incomplete 
at the acquisition date, and discounting the resulting net cash flows to their 
present value. The amount of research and development expended by Medicode on 
these projects prior to the acquisition date totaled $8.5 million, with 
another $2.2 million expected to be spent to complete these research and 
development projects. The in-process technology has not yet reached 
technological feasibility and has no alternative future use. The in-process 
projects were focused on the continued development and evolution of 
next-generation medical databases and software solutions. The $68 million 
charge is included as a component of Operational Realignment and Other 
Charges in the accompanying Consolidated Statements of Operations for the 
year ended December 31, 1998. Based on the final valuation, the remaining 
excess purchase price of $55 million was assigned to existing technologies, 
trade names and goodwill. The pro forma effects of the Medicode acquisition 
on our consolidated financial statements were not material.

          In April 1996, we completed the acquisition of HealthWise of 
America, Inc. (HealthWise). HealthWise owned or operated health plans in 
Maryland, Kentucky, Tennessee and Arkansas that served 154,000 members at the 
time of acquisition. We issued 4.3 million shares of common stock in exchange 
for all outstanding shares of HealthWise. We accounted for the acquisition as 
a pooling of interests; however, we did not restate our historical financial 
results because the effects of this acquisition on our consolidated financial 
statements were not material. In connection with the HealthWise acquisition, 
we incurred merger costs of $15 million.

          In March 1996, we completed the acquisition of PHP, Inc. (PHP), a 
North Carolina-based health plan that served 132,000 members at the time of 
acquisition. We issued 2.3 million shares of common stock, with a fair value 
of $140 million, in exchange for all outstanding shares of PHP. We accounted 
for the acquisition using the purchase method of accounting. The purchase 
price and costs associated with the acquisition exceeded the estimated fair 
value of net assets acquired by $115 million, which has been assigned to 
goodwill. The pro forma effects of the PHP acquisition on our consolidated 
financial statements were not material.

         We acquired MetraHealth in October 1995. MetraHealth was formed in 
January 1995 by combining the group health care insurance operations of 
Metropolitan Life Insurance Company and The Travelers Insurance Group. We 
accounted for the acquisition using the purchase method of accounting. The 
excess purchase price over the fair value of net assets acquired of $1.2 
billion was assigned to identifiable intangibles of $635 million in the 
Indemnity, Administrative Services Only and Specialty businesses consisting 
of employer group contracts and the supporting infrastructure, distribution 
networks and institutional knowledge being amortized over periods ranging 
from 10 to 40 years, with the remaining $560 million assigned to goodwill 
being amortized over 40 years.

(4) SPECIAL OPERATING CHARGES

OPERATIONAL REALIGNMENT AND OTHER CHARGES

In conjunction with our operational realignment initiatives, we developed and,
in the second quarter of 1998, approved a comprehensive plan (the Plan) to
implement our operational realignment. We recognized corresponding charges to
operations of $725 million in the quarter, which reflect the estimated costs we
will incur under the Plan. The charges included costs associated with asset
impairments; employee terminations; disposing of or discontinuing business
units, product lines and contracts; and consolidating and eliminating certain
processing operations and associated real estate obligations. These activities
will result in a net reduction of more than 4,000 positions affecting 6,000
people in various locations. Through December 31, 1998, we have eliminated
approximately 2,000 positions pursuant to the Plan.

                                    II-19

<PAGE>

     Our original provision for operational realignment and other charges was 
developed based on management's best judgment and estimates at that time. As 
we began to execute the Plan, we adjusted certain estimates based on more 
current information related to the amounts to be paid for severance and lease 
cancellation fees. In addition, based on continuing negotiations related to 
business dispositions, our original estimates for asset impairments and 
business disposition costs were revised. In total, our Operational 
Realignment and Other Charges did not change.

     The following table summarizes the components of the operational 
realignment and other charges for the year ended December 31, 1998 (in 
millions):

</TABLE>

     The asset impairments consist principally of goodwill and other 
long-lived assets, including fixed assets, computer hardware and software and 
leasehold improvements, from: 1) businesses we intend to dispose of or 
discontinue, 2) markets where we plan to curtail our operations or change the 
nature of our operating presence, or 3) the allocation of the purchase price 
for the acquisition of Medicode.

     Businesses we intend to dispose of include our managed workers' 
compensation business, and medical and behavioral health provider clinics. 
Markets where we plan to curtail or make changes to our operating presence 
include our small group health insurance business and three health plan 
markets that are in non-strategic locations. We prepared a forecast of 
expected undiscounted cash flows, where appropriate, to determine whether 
asset impairments existed. We used discounted cash flows to determine the 
fair value and measure the write-downs for two of the three health plans. We 
estimated proceeds on the sale of the managed workers' compensation, small 
group health insurance, clinical and other health plan businesses in order to 
determine the fair value and amount of asset write-down for these businesses. 
The final allocation of the purchase price for the acquisition of Medicode 
was based on an independent valuation. The asset impairments also consist of 
other operating assets written down to their net realizable value as a result 
of operational realignment activities. The carrying value of the net assets 
held for sale or disposal is approximately $20 million as of December 31, 
1998.

     Our accompanying financial statements include the operating results of 
businesses to be disposed of or discontinued in connection with the 
operational realignment. The losses anticipated on the disposition of these 
businesses, including severance, impairment of assets, abandoned facilities 
and additional exit costs, represent approximately $175 million and are 
included in the $725 million of operational realignment and other charges. 
Our accompanying Consolidated Statements of Operations include revenues and 
operating losses from these businesses as follows (in millions):

</TABLE>

     The table above does not include operating results from the counties 
where we will be withdrawing our health plan Medicare product offerings 
effective January 1, 1999. Annual revenues for 1998 from the Medicare 
counties we are exiting were approximately $225 million.

     The operational realignment charges do not cover certain aspects of the 
Plan, including new information systems, data conversions, process 
re-engineering, and employee relocation and training. These costs will be 
charged to expense as incurred or capitalized, as appropriate.

MEDICAL COSTS

During the second quarter of 1998, we recorded $175 million of medical cost 
charges. Of this amount, $101 million related to Medicare contract losses, 
$19 million related to other increases to Medicare medical costs payable 
estimates, and $55 million related to increases to commercial medical costs 
payable estimates.

     The $101 million of contract losses were incurred in 13 of our 24 
Medicare markets. These plans contribute half of our annual Medicare premiums 
of $2.4 billion. Six of these markets are generally newer markets where we 
have been unable to achieve the scale of operations necessary to achieve 
profitability. In numerous counties in the seven other markets, we experienced 
high medical costs which exceeded the fixed Medicare premiums that only 
increased 2.5% on average. We incurred $38 million of these Medicare losses 
during the second quarter and accrued $63 million at June 30, 1998, to cover 
estimated future losses to be incurred in the third and fourth quarters. We 
actually incurred $73 million of losses in the third and fourth quarters, and 
we recorded the additional $10 million as medical costs in the fourth quarter.

                                    II-20

(5) METRAHEALTH RESTRUCTURING CHARGES

In connection with our acquisition of The MetraHealth Companies, Inc. 
(MetraHealth) in 1995, we developed a comprehensive plan to integrate the 
business activities of the combined companies (the Plan). The Plan included, 
among other things, the disposition, discontinuance and restructuring of 
certain businesses and product lines, and the recognition of certain asset 
impairments. In the fourth quarter of 1995, we recorded $154 million in 
restructuring charges associated with the Plan.

     In conjunction with ongoing integration efforts, we modified the Plan 
during 1996. The restructuring reserves established with the original Plan 
were an accurate estimation of the costs incurred; however, we needed to 
reallocate the reserve estimates among the associated activities as the 
original Plan evolved.

     A reconciliation of MetraHealth restructuring activities for the years 
ended December 31 is as follows (in millions):

(6) PROVISION FOR FUTURE LOSSES

In the second quarter of 1996, we recorded a provision to medical costs of 
$45 million to cover estimated losses we expected to incur through the 
remaining terms of two large 28 contracts in our St. Louis health plan. One 
of the contracts expired in December 1998 and contained a premium rate 
increase cap of 2.5% per year. The other contract expires in December 2000 
and generally limits premium rate increases to annual Consumer Price Index 
adjustments. As of December 31, 1998, there were approximately 35,000 members 
under this contract.

     Our estimate of future revenues and losses under these contracts is as 
follows (in millions):

<TABLE>
<CAPTION>
                                                     Revenues          Losses
- -----------------------------------------------------------------------------
<S>                                                 <C>            <C>
1999 estimate                                        $     59       $     (6)
2000 estimate                                        $     61       $     (7)
- -----------------------------------------------------------------------------
</TABLE>

     We believe the remaining balance in the accrual for future losses of $13 
million, which is included in medical costs payable in the accompanying 
Consolidated Balance Sheets, will be sufficient to cover expected future 
losses from the remaining contract.

(7) AMERICAN ASSOCIATION OF RETIRED PERSONS

On January 1, 1998, we entered into a ten-year contract to provide insurance 
products and services to members of the AARP. Under the terms of the 
contract, we are compensated for claims administration and other services as 
well as for assuming underwriting risk. We are also engaged in product 
development activities to complement the insurance offerings under this 
program. The AARP has also contracted with certain other vendors to provide 
other member and marketing services. We report premium revenues associated 
with the AARP program net of the administrative fees paid to these vendors 
and an administrative allowance we pay to the AARP.

     Our underwriting results related to the AARP business are recorded as an 
increase or decrease to a rate stabilization fund (RSF). The RSF is included 
in other policy liabilities in the accompanying Consolidated Balance Sheets. 
The primary components of our underwriting results are premium revenue, 
medical costs, investment income, administrative expenses, member service 
expenses, marketing expenses and premium taxes. To the extent we incur 
underwriting losses that exceed the balance in the RSF, we would be required 
to fund the deficit. Any deficit we fund could be recovered by underwriting 
gains in future periods of the contract. The RSF balance was $192 million as 
of January 1, 1998, and is $509 million as of December 31, 1998. We believe 
the RSF balance is sufficient to cover any potential future underwriting or 
other risks associated with the contract.

     We assumed the policy and other liabilities related to the AARP program 
and received cash and premiums receivables from the previous insurance 
carrier equal to the carrying value of the liabilities assumed as of January 
1, 1998. The following assets and liabilities were transferred from the 
program's previous carrier and are included in our Consolidated Balance 
Sheets (in millions):

     Gross realized gains of $31 million, $24 million, and $10 million and

(9) DEBT

In November 1998, we issued $650 million of unsecured notes payable at a 
weighted-average interest rate of 6.0%. The debt placement consisted of $400 
million in unsecured notes due December 1, 1999, with an interest rate of 
5.65% and $250 million in unsecured notes due December 1, 2003, with an 
interest rate of 6.65%.

     In December 1998, we also established a $600 million commercial paper
program, thereby providing increased flexibility in managing our capital
structure. At December 31, 1998, we had $59 million in commercial paper
borrowings outstanding at an average interest rate of 5.3%.

     In support of our commercial paper program, we entered into a $600 
million credit arrangement with a group of banks. The agreement is comprised 
of a $300 million five-year revolving credit facility and a $300 million 
364-day credit facility. No borrowings were outstanding as of December 31, 
1998, under the credit facilities. Debt consists of the following as of 
December 31, 1998:

     The Company's debt arrangements and credit facilities contain various 
covenants, the most restrictive of which place limitations on secured and 
unsecured borrowings and require the Company to exceed minimum interest 
coverage levels. As of December 31, 1998, we are well within the requirements 
of all debt covenants.

     Maturities of debt for the years ending December 31, are as follows (in 
millions):

     The carrying value of the Company's outstanding debt approximates its 
fair value at December 31, 1998.

(10) CONVERTIBLE PREFERRED STOCK

In December 1998, we redeemed all 500,000 outstanding shares of 5.75% Series 
A Convertible Preferred Stock (the Preferred Stock). The Preferred Stock was 
issued to certain former shareholders of MetraHealth as a portion of the 
total consideration of our 1995 acquisition of MetraHealth. The redemption 
price per share of stock was $1,040 per share, or $520 million in the 
aggregate, which included a redemption premium of $40 per share, or $20 
million in the aggregate. The redemption premium of $20 million is deducted 
from net earnings (loss) to arrive at net earnings (loss) applicable to 
common shareholders in the accompanying Consolidated Statements of Operations.

(11) SHAREHOLDERS' EQUITY

REGULATORY CAPITAL AND DIVIDEND RESTRICTIONS

The Company's operations are conducted through United HealthCare Corporation, 
its wholly-owned subsidiary United HealthCare Services, Inc. and their 
respective subsidiaries, which consist principally of Health Maintenance 
Organizations (HMOs) and insurance companies. HMOs and insurance companies 
are subject to state regulations that, among other things, may require the 
maintenance of minimum levels of statutory capital, as defined by each state, 
and restrict the timing and amount of dividends and other distributions that 
may be paid to their respective parent companies. Generally, the amount of 
dividend distributions that may be paid by regulated insurance and HMO 
companies, without prior approval by state regulatory authorities, is limited 
based on the entity's level of statutory net income and statutory capital and 
surplus.

     As of December 31, 1998, the Company's regulated subsidiaries had 
aggregate statutory capital and surplus of approximately $1.4 billion, 
compared with their aggregate minimum statutory capital and surplus 
requirements of $390 million. The amount of dividends that may be paid to the 
Company or United HealthCare Services, Inc. by their insurance and HMO 
subsidiaries at December 31, 1998, without prior approval by state regulatory 
authorities, is limited to approximately $120 million. There are no such 
restrictions on distributions from United HealthCare Services, Inc. to the 
Company or on distributions from the Company to its shareholders.

                                    II-23

<PAGE>

    The National Association of Insurance Commissioners has adopted rules 
which, to the extent that they are implemented by the states, will set new 
minimum capitalization requirements for insurance companies, HMOs, and other 
entities bearing risk for health care coverage. The requirements take the form 
of risk-based capital rules. The change in rules for insurance companies was 
effective December 31, 1998. The new HMO rules are subject to state-by-state 
adoption, but few states had adopted the rules as of December 31, 1998. The HMO 
rules, if adopted by the states in their proposed form, would significantly 
increase the capital required for certain of our subsidiaries. However, we 
believe we can redeploy capital among our regulated entities to minimize the 
need for incremental capital investment of general corporate financial 
resources into regulated subsidiaries. As such, we do not anticipate a 
significant impact on our aggregate capital or investments in regulated 
subsidiaries.

STOCK REPURCHASE PROGRAM

Pursuant to a board of directors' authorization, we are operating an 18.7 
million share common stock repurchase program. These repurchases may be made 
from time to time at prevailing prices, subject to certain restrictions on 
volume, pricing and timing. During 1998, we repurchased 11.3 million shares for 
an aggregate cost of $436 million, an average cost of approximately $40 per 
share.

DIVIDENDS

On February 16, 1999, the board of directors approved an annual dividend for
1999 of $0.03 per share payable on April 15, 1999, to holders of common stock as
of close of business April 1, 1999.

(12) STOCK-BASED COMPENSATION PLANS

We have stock and incentive plans (the Stock Plans) for the benefit of eligible 
employees. As of December 31, 1998, the Stock Plans allowed for the future 
granting of up to 5 million shares as incentive or non-qualified stock options, 
stock appreciation rights, restricted stock awards, and performance awards to 
employees.

     In 1995, we adopted the Non-employee Director Stock Option Plans (the 1995 
Plan) to benefit members of the board of directors who are not employees. As of 
December 31, 1998, 34,000 shares were available for future grants of 
non-qualified stock options under the 1995 Plan.

     Stock options are generally granted at an exercise price not less than the 
fair market value of the common stock at the date of grant. They may be 
exercised over varying periods up to 10 years from the date of grant.

     We increased additional paid-in capital $47 million in 1998, $37 million 
in 1997, and $15 million in 1996 to reflect the tax benefit we received upon 
the exercise of non-qualified stock options.

     We do not recognize compensation expense in connection with stock option 
grants because we grant stock options at exercise prices that equal or exceed 
the fair market value of the stock at the time options are granted. If we had 
determined compensation expense using fair market values for stock options 
granted, net earnings (loss) would have been reduced to the following pro forma 
amounts:

     To determine compensation cost under the fair value method, the fair value 
of each option grant is estimated on the date of grant using the Black-Scholes 
option-pricing model.

     Principal assumptions used in applying the Black-Scholes model were as 
follows:

- -----------------------------------------------------------------------
</TABLE>

     Because we did not apply the fair value method of accounting to options 
granted prior to January 1, 1995, the resulting pro forma compensation cost may 
not be representative of what can be expected in future years.

EMPLOYEE STOCK OWNERSHIP PLAN

We have a non-leveraged Employee Stock Ownership Plan (the ESOP) for the 
benefit of all eligible employees. Company contributions to the ESOP are made 
at the discretion of the board of directors. We made contributions to the ESOP 
of $4 million in 1998, $4 million in 1997, and $3 million in 1996.

EMPLOYEE STOCK PURCHASE PLAN

The Employee Stock Purchase Plan (the ESPP) allows all eligible employees to 
purchase shares of common stock on semiannual offering dates at a price that is 
the lesser of 85% of the fair market value of the shares on the first day or 
the last day of the semiannual period. Employee contributions were $19 million 
for 1998, $17 million for 1997, and $16 million for 1996. Through the ESPP, we 
issued to employees 206,000 shares in 1998, 422,000 in 1997, and 392,000 shares 
in 1996. As of December 31, 1998, 3.0 million shares were available for future 
issuance.

     Valuation allowances are provided when it is considered unlikely that 
deferred tax assets will be realized. The valuation allowance relates to future 
tax benefits on certain purchased domestic and foreign net operating losses.

     We paid income taxes of $245 million in 1998, $124 million in 1997, and 
$96 million in 1996.

     Consolidated income tax returns for fiscal years 1995 and 1994 were 
examined by the Internal Revenue Service (IRS). The audit was concluded with no 
material impact on our consolidated operating results or financial position.

     Consolidated income tax returns for fiscal years 1997 and 1996 are 
currently being examined by the IRS. We do not believe any adjustments that may 
result will have a material effect on our consolidated operating results or 
financial position.

(14) COMMITMENTS AND CONTINGENCIES

LEASES

We lease facilities, computer hardware and other equipment under long-term 
operating leases that are noncancelable and expire on various dates through 
2011. Rent expense under all operating leases was $119 million in 1998, $104 
million in 1997, and $114 million in 1996.

     At December 31, 1998, future minimum annual lease payments under all 
noncancelable operating leases were as follows (in millions):

SERVICE AGREEMENTS

In June 1996 and November 1995, we entered into separate 10-year contracts with 
nonaffiliated third parties for information technology services. Under the 
terms of the contracts, the third parties assumed responsibility for certain 
data center operations and support. In September 1996, we entered into a 
10-year contract with a third party for certain data network and voice 
communication services. Future payments under all of these contracts are 
estimated to be $1.3 billion; however, the actual timing and amount of payments 
will vary based on usage. Expenses incurred in connection with these agreements 
were $162 million in 1998, $125 million in 1997, and $70 million in 1996.

LEGAL PROCEEDINGS

Six suits assert claims under the United States securities laws against 
UnitedHealth Group and certain of its current and former officers and 
directors. The plaintiffs are shareholders of the Company who purport to sue on 
behalf of a class of purchasers of the Company's common shares during the 
period February 12, 1998, through August 5, 1998 (the "Class Period"). Each 
complaint was filed in the United States District Court for the District of 
Minnesota. Each of the six actions claims violations of Sections 10(b) and 
20(a) of the Securities Exchange Act and SEC Rule 10b-5. In substance, the 
complaints allege that the Company made materially false or misleading 
statements about the profitability and performance of the Company's Medicare 
business during the Class Period. Two of the complaints also allege that the 
Company made materially false statements about its medical costs and the 
expenses related to its realignment. The complaints also allege that the 
statements were made with the intention of deceiving members of the investing 
public and with the intention that the price of the Company's shares would 
rise, making it possible for insiders at the Company to profit by selling 
shares at a time when they knew the Company's true financial condition, but the 
investing public did not. The complaints allege that once the Company's true 
financial condition was revealed on August 6, 1998, the price of its common 
shares fell from a closing price of $52 7/8 per share on August 5, 1998, to a 
closing price of $37 7/8 per share on August 6, 1998. The complaints seek 
compensatory damages in unspecified amounts.

     On January 19, 1999, we received a consolidated amended complaint (In re 
United HealthCare Corporation Securities Litigation, No. 98-1888 in the United 
States District Court for the District of Minnesota) for the six suits which 
essentially restates the allegations made in the earlier complaints.

     On March 22, 1999, two actions were filed in the United States District 
Court for the District of Minnesota by two pension funds against United, 
certain current and former officers and directors, and other individuals yet 
to be identified. The pension funds wish to "opt-out" of the aforementioned 
purported class action suits. These individual actions essentially restate 
the allegations made in the purported class actions and claim violations of 
Sections 10(b), 18(a) and 20 of the Securities Exchange Act. In addition, 
both actions assert a claim of negligent misrepresentation and securities 
claims under state law. In the aggregate, the plaintiff pension funds seek 
compensatory damages totaling approximately $12.1 million.

     We intend to defend these actions vigorously.

     We are also involved in other legal actions that arise in the ordinary 
course of business. Although we cannot predict outcomes of legal actions, it is 
our opinion that the resolution of all currently pending or threatened actions, 
including the class action lawsuit described above, will not have an adverse 
effect on our consolidated financial position or results of operations.

BUSINESS RISKS

Certain factors relating to the health care industry and our business should be
carefully considered. Companies offering health care coverage and health care
management services are heavily regulated at federal and state levels. While we
cannot predict regulatory changes or their impact, it is possible that
operations and financial results could be negatively affected.

     After several years of moderate increases in health care costs and 
utilization, the industry experienced a pronounced increase during 1996. 
Although the rate of these increases appears to have stabilized, there is no 
assurance that health care costs and utilization will not continue to increase 
at a more rapid pace. If they do, we may not be able to meet our objective of 
maintaining price increases at least sufficient to cover health care cost 
increases.

     Additionally, the health care industry is highly competitive and has seen 
significant consolidation over the past few years. The current competitive 
markets in certain areas may limit our ability to price products at appropriate 
levels. These competitive factors may adversely affect our consolidated 
financial results.

CONCENTRATIONS OF CREDIT RISK

Investments in financial instruments such as marketable securities and
commercial premiums receivable may subject UnitedHealth Group to concentrations
of credit risk. Our investments in marketable securities are managed by
professional investment managers within an investment policy authorized by the
board of directors. This policy limits the amounts that may be invested in any
one issuer. Concentrations of credit risk with respect to commercial premiums
receivable are limited to the large number of employer groups that comprise our
customer base. As of December 31, 1998, there were no significant concentrations
of credit risk.

QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

Since the date of the Company's quarterly report filed on Form 10-Q for the
quarter ended September 30, 1998, no material changes have occurred in the
Company's exposure to market risk associated with our investments in market
risk-sensitive financial instruments. We do not believe that our risk of a loss
in future earnings or a decline in fair values or cash flow attributable to such
investments is material.


(15) SEGMENT FINANCIAL INFORMATION

Our accounting policies for our business segment operations are the same as
those described in the Summary of Significant Accounting Policies (see Note 2).
Transactions between business segments are recorded at their estimated fair
value, as if they were purchased from or sold to third parties. All intersegment
transactions are eliminated in consolidation. Generally accepted accounting
principles provide for the combined reporting of segments with similar economic
characteristics. Accordingly, the financial results of UnitedHealthcare and
Ovations have been combined to form the Health Care Services segment in the
tables presented below (in millions):

REPORT OF INDEPENDENT
PUBLIC ACCOUNTANTS


TO THE SHAREHOLDERS AND DIRECTORS OF UNITEDHEALTH GROUP:

We have audited the accompanying consolidated balance sheets of UnitedHealth
Group and its corporate entity, United HealthCare Corporation (a Minnesota
Corporation), and Subsidiaries as of December 31, 1998 and 1997, and the related
consolidated statements of operations, changes in shareholders' equity and cash
flows for each of the three years in the period ended December 31, 1998. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these financial statements based on
our audits.
    We conducted our audits in accordance with generally accepted auditing 
standards. Those standards require that we plan and perform the audit to 
obtain reasonable assurance about whether the financial statements are free 
of material misstatement. An audit includes examining, on a test basis, 
evidence supporting the amounts and disclosures in the financial statements. 
An audit also includes assessing the accounting principles used and 
significant estimates made by management, as well as evaluating the overall 
financial statement presentation. We believe that our audits provide a 
reasonable basis for our opinion.
    In our opinion, the financial statements referred to above present 
fairly, in all material respects, the financial position of UnitedHealth 
Group and Subsidiaries as of December 31, 1998 and 1997, and the results of 
their operations and their cash flows for each of the three years in the 
period ended December 31, 1998, in conformity with generally accepted 
accounting principles.

REPORT OF MANAGEMENT

The management of UnitedHealth Group is responsible for the integrity and 
objectivity of the consolidated financial information contained in this 
annual report. The consolidated financial statements and related information 
were prepared according to generally accepted accounting principles and 
include some amounts that are based on management's best estimates and 
judgements.
    To meet its responsibility, management depends on its accounting systems 
and related internal accounting controls. These systems are designed to 
provide reasonable assurance, at an appropriate cost, that financial records 
are reliable for use in preparing financial statements and that assets are 
safeguarded. Qualified personnel throughout the organization maintain and 
monitor these internal accounting controls on an ongoing basis. Internal 
auditors review the accounting practices, systems of internal control and 
compliance with these practices and controls.
    The Audit Committee of the board of directors, composed entirely of 
directors who are not employees of the Company, meets periodically and 
privately with the Company's independent public accountants and its internal 
auditors, as well as management, to review accounting, auditing, internal 
control, financial reporting and other matters.

     UNITED HEALTHCARE CORPORATION, a Minnesota corporation (hereinafter 
called the "Company", which term includes any successor corporation under the 
Indenture referred to below), for value received, hereby promises to pay to 
CEDE & CO., or registered assigns, the principal sum of __________________ 
DOLLARS ($_____________) on December 1, 1999 (the "Stated Maturity"), and to 
pay interest thereon from __________________ or from the most recent date to 
which interest has been paid or duly provided for, semi-annually on June 1 
and December 1 in each year (each, an "Interest Payment Date"), commencing 
__________________ , and at Maturity, at the rate of 5.65% per annum, until 
the principal hereof is paid or duly made available for payment.  Interest on 
this Note shall be calculated on the basis of a 360-day year consisting of 
twelve 30-day months.  The interest so payable and punctually paid or duly 
provided for on any Interest Payment Date will, as provided in such 
Indenture, be paid to the Person in whose name this Note

<PAGE>

(or one or more predecessor Notes) is registered at the close of business on 
the "Regular Record Date" for such interest, which shall be the May 15 or the 
November 15 (whether or not a Business Day) next preceding such Interest 
Payment Date; PROVIDED, HOWEVER, that interest payable at the Maturity of 
this Note shall be payable to the Person to whom principal shall be payable.  
Any such interest which is payable, but is not punctually paid or duly 
provided for, on any Interest Payment Date shall forthwith cease to be 
payable to the registered Holder hereof on the relevant Regular Record Date 
by virtue of having been such Holder, and may be paid (i) to the Person in 
whose name this Note (or one or more predecessor Notes) is registered at the 
close of business on a Special Record Date for the payment of such Defaulted 
Interest to be fixed by the Trustee, notice whereof shall be given to the 
Holder of this Note not less than 10 days prior to such Special Record Date 
or (ii) in any other lawful manner not inconsistent with the requirements of 
any securities exchange on which such Notes may be listed, and upon such 
notice as may be required by such exchange, if, after notice given by the 
Company to the Trustee of the proposed payment pursuant to this clause (ii), 
such manner of payment shall be deemed practicable by the Trustee.  In the 
event that any Interest Payment Date or date of Maturity is not a Business 
Day, the interest and, with respect to the date of Maturity, principal 
otherwise payable on such date will be paid on the next succeeding Business 
Day with the same force and effect as if made on such Interest Payment Date 
or on such date of Maturity.  "Business Day" shall mean any day that is not a 
Saturday or Sunday and that, in the City of New York, is not a day on which 
banking institutions are generally authorized or obligated by law to close.

     Payment of the principal of and the interest on this Note will be made 
at the office or agency of the Company maintained for that purpose in The 
City of New York, in such coin or currency of the United States of America as 
at the time of payment is legal tender for payment of public and private 
debts; PROVIDED, HOWEVER, that, at the option of the Company, interest may be 
paid by check mailed to the address of the Person entitled thereto as such 
address shall appear in the Security Register.   Payment of the principal of 
and interest on this Note due at Maturity will be made in immediately 
available funds upon presentation of this Note. 

     Reference is hereby made to the further provisions of this Note set 
forth on the reverse hereof, which further provisions shall for all purposes 
have the same effect as if set forth at this place.

     Unless the certificate of authentication hereon has been executed by or

                        5.65% NOTES DUE DECEMBER 1, 1999

                            [REVERSE SIDE OF NOTE]

     This Note is one of a duly authorized issue of securities of the Company 
(herein called the "Notes") issued and to be issued in one or more series 
under an Indenture dated as of  November 15, 1998, as supplemented pursuant 
to Section 301 thereof by the Officers' Certificate and Company Order dated 
November 24, 1998 (herein called, the "Indenture") between the Company and 
The Bank of New York, as Trustee (herein called the "Trustee", which term 
includes any successor trustee under the Indenture), to which Indenture and 
all indentures supplemental thereto reference is hereby made for a statement 
of the respective rights, limitations of rights, duties and immunities 
thereunder of the Company, the Trustee and the Holders of the Notes, and the 
terms upon which the Notes are, and are to be, authenticated and delivered.  
This Note is one of the series designated on the face hereof, limited in 
aggregate principal amount to $                        . 

REDEMPTION

     The Notes are not subject to redemption prior to the Stated Maturity.

MISCELLANEOUS PROVISIONS

     If an Event of Default with respect to the Notes shall occur and be 
continuing, the principal of the Notes may be declared due and payable in the 
manner and with the effect provided in the Indenture.

     The Indenture contains provisions for defeasance at any time of the 
Company's obligations in respect of (i) the entire indebtedness of this Note 
or (ii) certain restrictive covenants with respect to this Note, in each case 
upon compliance with certain conditions set forth therein.

     The Indenture permits, with certain exceptions as therein provided, the 
amendment thereof and the modification of the rights and obligations of the 
Company and the rights of the Holders of the Securities of each series issued 
under the Indenture at any time by the Company and the Trustee with the 
consent of the Holders of not less than a majority in aggregate principal 
amount of the Securities at the time Outstanding of each series affected 
thereby.  The Indenture also contains provisions permitting the Holders of 
specified percentages in aggregate principal amount of the Securities of any 
series at the time Outstanding to waive certain past defaults under the 
Indenture and their consequences.  Any such consent or waiver by the Holder 
of this Note shall be conclusive and binding upon such Holder and upon all 
future Holders of this Note and of any Notes issued upon the registration of 
transfer hereof or in exchange herefor or in lieu hereof, whether or not 
notation of such consent or waiver is made upon this Note.

     No reference herein to the Indenture and no provision of this Note or of 
the Indenture shall alter or impair the obligation of the Company, which is 
absolute and unconditional, to pay the principal of (and premium, if any) and 
interest on this Note, at the time, place and rate, and in the coin or 
currency, herein and in the Indenture prescribed.


<PAGE>

     As provided in the Indenture and subject to certain limitations set 
forth therein and in this Note, the transfer of this Note is registrable in 
the registry books of the Company, upon surrender of this Note for 
registration of transfer at the office or agency of the Company maintained 
for the purpose in any place where the principal of (and premium, if any) and 
interest on this Note are payable, duly endorsed, or accompanied by a written 
instrument of transfer in form satisfactory to the Company and the Trustee 
duly executed by the Holder hereof or by his attorney duly authorized in 
writing, and thereupon one or more new Notes, of authorized denominations and 
for the same aggregate principal amount, will be issued to the designated 
transferee or transferees.

without coupons in minimal initial purchase amounts of $100,000 and any 
amount in excess thereafter which is an integral multiple of $1,000.  As 
provided in the Indenture and subject to certain limitations therein set 
forth, Notes of this series are exchangeable for a like aggregate principal 
amount of Notes of this series and of like tenor of a different authorized 
denomination, as requested by the Holder surrendering the same.

     No service charge shall be made for any such registration of transfer or 
exchange, but the Company may require payment of a sum sufficient to cover 
any tax or other governmental charge payable in connection therewith, other 
than in certain cases provided in the Indenture.

                                                  MANAGEMENT INCENTIVE PLAN


The realignment of United HealthCare into six strategically aligned, but
independent business segments established a framework for our company's ongoing
growth and opportunity well into the next century.  One of the principal
advantages the new structure offers is the capability to leverage our
considerable resources and capacity, while still nurturing and sustaining the
entrepreneurial spirit that brought us to where we are today.

Our compensation programs have been and will continue to be structured to
encourage leaders to strive for and be rewarded for excellence and continuous
improvement.  The belief in pay for performance is inherent in our culture.  The
1998 Management Incentive Program carries this philosophy forward within the
framework of our new organization by aligning incentive pools and measurement
goals not only with overall company and individual results, but also more
closely with business segment and business/corporate unit results.

We will measure our success against the goals we set for ourselves, not against
the benchmarks or predictions set by Wall Street.  To be truly great, we must
reach for the future.  We must believe in ourselves and in what we are capable
of achieving.  

This is and will continue to be a challenging year.  While part of our energies
must go into continuing to shape and construct our new organization, we also
must achieve even higher levels of growth and financial performance in a dynamic
and competitive environment.  We must deliver high quality service and improved
product choices for our customers.  And we must remain focused on appropriate
health care delivery, operating and medical cost trends.

As leaders of United HealthCare, we set the standards of excellence for the
organization.  I believe we can achieve great things.

                                           William W. McGuire, MD
                                           President, Chairman and

- ------------------------------------------------------------------------------


OVERVIEW

Annual management incentive plan funding and payout amounts are determined by
the overall performance of United HealthCare, as well as the performance of your
Business Segment,  Business Unit/Corporate or Enterprise Services group  and 
your individual performance as compared to the goals and objectives established
in our internal business planning process as shown in the diagram on page 4 and
as described below:

1)      The OVERALL PERFORMANCE OF UNITED HEALTHCARE will be measured by
accomplishment of strategic initiatives, employment of capital and resources,
market valuation, merger and acquisition activity, and public image and
recognition, as well as financial results in the following categories: earnings,
earnings per share, revenue, operating costs, medical care ratio, growth and
membership.  Strategic and financial goals have been determined by the Office of
the Chairman and are imbedded in our current year operating plans.

2)      United HealthCare is now organized into six business segments. The
OVERALL FINANCIAL AND STRATEGIC PERFORMANCE OF EACH BUSINESS SEGMENT WILL BE 
DETERMINING FACTORS FOR EACH BUSINESS SEGMENT AND BUSINESS UNIT PARTICIPANT. If
you are part of a United HealthCare business segment, your strategic and 
financial goals will be determined jointly by Senior Leaders and the Office
of the Chairman.

3)      The OVERALL FINANCIAL AND STRATEGIC PERFORMANCE OF YOUR BUSINESS UNIT/
CORPORATE OR ENTERPRISE SERVICES GROUP WILL BE CONSIDERED.  If you are part of a
business unit, goals will be developed jointly by your Senior Leader and the
person to whom they report.  If you are part of the corporate or enterprise
services group, goals will be established by the appropriate Senior Leader and
the person to whom they report.

4)      INDIVIDUAL PERFORMANCE and accomplishment of individual goals and
objectives are also considered in determining incentive awards.

All four performance measures are used to determine incentive pools and
incentive awards. This blend of performance measurements helps ensure that all
of United HealthCare works together toward common goals and allows us the
greatest opportunities for success professionally and personally. The company's
internal targeted goals and measures always exceed the externally anticipated
results held by the investment community.

INCENTIVE POOLS

Incentive pools for 1998 will be more closely aligned with the results of the
business segments and business units to reflect the operational realignment of
the organization.  Performance against the internal goals at these levels and
the company's overall performance will determine the size of the incentive
pools.  Corporate and Enterprise Service units will be aligned with overall
company performance and the results of their unit objectives.

INCENTIVE TARGETS

Incentives are an important part of your total compensation package.  Each
participant is assigned an MIP Incentive Target percent.  This target percent is
determined by your grade, overall level of responsibility within the
organization and market competitiveness.


The calculation of the incentive pools will generally be determined as follows
with the final decision on incentive pools subject to the discretion of the
company's top management:

Your targeted incentive award is determined by your eligible base earnings paid
during the fiscal year multiplied by your MIP Target percent (or prorated target
percent if it changed during the year).

Your senior business leader will communicate this year's overall company,
business segment, business unit/corporate or enterprise services and individual
goals.


MIP PROGRAM

STEP 1 - ESTABLISHMENT OF TOTAL INCENTIVE POOL

At the end of United HealthCare's fiscal year, the Compensation and Stock Option
Committee of the Board of Directors will review the overall financial and
strategic results of each business segment in order to determine the overall
company performance and the total amount available in the incentive pool.

The Compensation and Stock Option Committee will approve an incentive pool
amount.


STEP 2 - ESTABLISHMENT OF BUSINESS SEGMENT, CORPORATE & ENTERPRISE SERVICES
POOLS

Business segment and business unit performance will play an increased role in
determining incentive pools.  Once the company overall incentive pool is 
established, Senior Leaders will determine the performance and incentive pools
specific to the business segments.

The ratings for determining incentive pool amounts for individual business
segments and units may exceed or be less than that of the overall company
rating.

STEP 3 - ESTABLISHMENT OF BUSINESS UNIT POOLS

Business segment senior leaders and corporate top management will be responsible
for allocating the pools among the business units and corporate divisions based
on their relative performance.


STEP 4 - ESTABLISHMENT OF INDIVIDUAL INCENTIVE PAYMENTS

After pools are established and allocated to each entity, management will then
shift the focus to the individuals in their groups to determine individual
incentive awards.   Incentive awards will be  based on individual performance
and accomplishment of objectives.

ELIGIBILITY

Generally, full-time regular employees grade 28 and above are eligible for MIP
awards.  At this level, positions are directly accountable for meeting key
corporate/enterprise, business segment or business unit objectives, generally 
manage staff, and determine and manage financial resources and budgets. Certain
positions are not eligible for MIP due to participation in other incentive
plans, even if they meet the eligibility criteria.

- -    If you were hired or promoted during the year to an MIP eligible position,
     your participation will be prorated for the time you serve as an eligible
     employee.  New hires and promotions to MIP eligible positions in the FOURTH
     QUARTER of a plan year are eligible for the plan in the following year but
     are not eligible to participate in the plan for the current year.  
     However, employees who were eligible for the performance incentive plan
     (PIP) or business incentive plan (BIP) prior to their promotion in the
     fourth quarter are eligible for a year-end PIP or BIP award.

- -    Participants eligible for a full or partial year MIP award are not eligible
     for PIP or BIP.

- -    If you are promoted to a position that carries a higher management
     incentive target, any incentive paid to you would be based on a combination
     of both your existing and new incentive targets.  The targets are weighted
     according to the time you held each position.  Your bonus is based on your
     eligible fiscal year base earnings and MIP target (prorated if necessary).

- -    If you are on leave of absence during the performance measurement period,
     any pay received during the leave (e.g., short term disability) will not be
     included in your eligible base earnings for purposes of calculating the
     amount of the incentive payment.

- -    If a participant transfers during the year from an MIP eligible position to
     a non-eligible position (e.g. sales), they will not be eligible for a
     partial MIP incentive.  Employees must be classified as eligible at
     year-end to receive an MIP award.

- -    If an MIP participant is reclassified to part-time or temporary status,
     they are eligible for an MIP award in the current year if the
     reclassification occurs after year-end.

- -    MIP payout for employees rehired in the same  MIP year will only be based
     on eligible base earnings from the employees date of re-hire.  Earnings
     from service prior to their rehire date will not be considered.

- -    To be eligible for a management incentive payment, you must be an active
     employee at the time such payments are made.  Employees who terminate
     employment prior to the date incentive awards are paid-out are not eligible
     for any awards.  If you are on a leave of absence and are scheduled to
     receive an incentive, you will receive that award upon your return to work.
     Employees who do not return to work from leave are not eligible to receive
     an incentive award.

EMPLOYEES ON FORMAL DISCIPLINARY ACTION ARE NOT ELIGIBLE FOR AN INCENTIVE
PAYMENT.

The senior vice president of Human Resources will determine any exceptions to
eligibility guidelines.

<PAGE>

401(K) PLAN AND ESOP CONTRIBUTIONS

Management Incentive Plan payments are considered compensation under the United
HealthCare 401(k) plan and Employee Stock Ownership  Plan.  In addition,
incentive payments are included in benefits compensation for employees enrolled
in the flexible benefit plans.

However, management incentive payments are not eligible for contributions to the
United HealthCare Employee Stock Purchase Plan.



PAYMENTS


Management Incentive Plan payments generally are made during the first quarter
following the close of the corporate and business segment books for the fiscal
year.

For questions regarding the Management Incentive Plan, contact your manager, the
head of your business unit or your human resources generalist.



THERE IS NO GUARANTEE THAT ANY MANAGEMENT INCENTIVE PLAN PAYOUTS WILL BE MADE.
UNITED HEALTHCARE HAS THE EXCLUSIVE AND BINDING DISCRETION TO AMEND, TERMINATE
OR INTERPRET THE TERMS OR CONDITIONS OF THE MANAGEMENT INCENTIVE PLAN AT ANY
TIME AND WITHOUT NOTICE.  CHANGES TO THIS PLAN MUST BE MADE IN WRITING BY THE
SENIOR VICE PRESIDENT OF HUMAN RESOURCES OR THE CHIEF EXECUTIVE OFFICER OF THE
COMPANY.  UNITED HEALTHCARE ALSO HAS THE DISCRETION TO UNILATERALLY MAKE BOTH
LEGAL AND FACTUAL DETERMINATIONS REGARDING THE PLAN.  THIS MANAGEMENT INCENTIVE
PLAN IS NOT AND SHALL NOT BE DEEMED TO BE AN ENFORCEABLE CONTRACT OR AN EMPLOYEE
BENEFIT PLAN WITHIN THE MEANING OF ERISA.

ADVANTAGES OF THE EXECUTIVE SAVINGS PLANS FOR YOU

  including the maximum tax deferral opportunity and company matching 
  contributions, by automatically enrolling you in the ESP Automatic 
  Restoration Option and allowing you to defer your MIP bonus under the 
  Incentive (MIP) Deferral Option; and

- - Have been designed to be flexible and allow you to choose among the various 
  options to develop an individual deferral strategy that best meets your 
  personal financial needs.

                                                                              1

IMPORTANT INFORMATION ABOUT THE EXECUTIVE SAVINGS PLANS

WHY EXECUTIVE SAVINGS PLANS

At United HealthCare, we are committed to providing you opportunities that 
help you prepare for a financially secure future. The 401(k) Savings Plan, 
Employee Stock Ownership Plan and Employee Stock Purchase Plan offer all 
eligible employees options for accumulating savings and retirement assets.

However, these plans are subject to restrictive tax rules. Recognizing that 
these rules limit the amount you can defer into those plans, United 
HealthCare created the Executive Savings Plans. These non-qualified deferred 
compensation plans allow you to defer virtually as much of your compensation 
as you wish through means that leverage the current tax environment.

The Plans are not subject to the same restrictions placed upon qualified 
plans, such as the annual 401(k) elective deferral dollar limits or 
compensation limits. The Plans are unfunded plans, which means that funds or 
contributions are not set aside in a trust and are subject to the claims of 
the general creditors of United HealthCare. Each plan is intended to be an 
unfunded pension plan maintained by United HealthCare for a select group of 
management or highly compensated employees.

WHO IS ELIGIBLE

To participate in the Executive Savings Plans, you must meet certain 
eligibility requirements.

1. For all Options, you must be an employee with at least 30 days of service 
   in an eligible class at United HealthCare. The following are eligible 
   classes in 1998:

   AUTOMATIC RESTORATION OPTION, INCENTIVE (MIP) DEFERRAL OPTION AND SALARY 
   DEFERRAL OPTION:

   - Grades 33 and above

   - Medical Directors M2 - M4

   - Clinical Medical Staff DC2 - CD3, CM2 - CM3

   LIMITED BONUS DEFERRAL OPTION:

   - As designated by the Board of Directors

2

<PAGE>

2. Participation under the Plans is available the first day of the calendar 
   month following completion of the 30-day eligibility requirement. Employees 
   who become newly eligible during the year will receive enrollment materials 
   prior to their eligibility date.

3. To participate in the Automatic Restoration Option, you must participate 
   in the 401(k) Savings Plan and reach one of the following IRS limits during 
   1998:

   - Earn $160,000 in eligible compensation (the same limit was applicable in 
     1997)

   - Make 401(k) Savings Plan deferrals that reach the 1998 IRS annual limit 
     of $10,000 (increased from $9,500 in 1997)

   YOU WILL AUTOMATICALLY BE ENROLLED IN THIS OPTION, AS DESCRIBED IN FURTHER 
   DETAIL ON THE NEXT PAGE, UNLESS YOU ELECT NOT TO PARTICIPATE.

4. You may enroll in the Incentive (MIP) Deferral Option for 1998 only during 
   the December 1997 enrollment period or when you become newly eligible during
   the year.

5. Enrollment for the Salary Deferral Option may be made for 1998 during the 
   December 1997 enrollment period or during the 1998 calendar year for future 
   1998 earnings.

                                                                             3

<PAGE>

HOW THE PLANS WORK

AUTOMATIC RESTORATION OPTION MIRRORS 401(K)

As long as you participate in the 401(k) Savings Plan, you automatically 
participate in the ESP Automatic Restoration Option. The Option:

- - Automatically defers the same percentage amount of your eligible pay on a 
  pre-tax basis that you contribute to the 401(k) Savings Plan, after your 
  401(k) Savings Plan elective deferrals reach the 1998 IRS dollar limit of 
  $10,000 or when you earn $160,000 in eligible pay; and

- - Provides a United HealthCare matching contribution of 50 cents for each 
  dollar deferred, up to the first six percent of your eligible pay. These 
  matching contributions receive the same investment credits that you elect for 
  your own contributions.

When you reach one of the IRS 401(k) annual limits (listed above), your 
Automatic Restoration Option deferrals begin in the following pay period. If 
you do not wish to participate in the Automatic Restoration Option, you may 
"opt out" by electing not to participate in this Option on the Deferral 
Election Form.

INCENTIVE (MIP) DEFERRAL OPTION OFFERS COMPANY MATCH

This Option allows you to defer a portion or all of your Management Incentive 
Plan (MIP) bonus (1997 MIP bonus paid in 1998) into the ESP and receive a 
company matching contribution. Enrollment in this Option is the only way to 
get an employer match on your MIP bonus.

You may defer 6 percent, 25 percent, 50 percent, 75 percent, or 100 percent 
of your bonus by making a one-time election prior to the beginning of each 
calendar year. You may not change your incentive deferral election during the 
year. You will receive a company matching contribution of 50 cents on every 
dollar you defer up to 6 percent of your total Incentive (MIP) Deferral 
Option amount.

SALARY DEFERRAL OPTION OFFERS FLEXIBILITY

With this Option, you can defer from 1 percent to 100 percent of all 1998 
eligible pay, excluding MIP bonus payments. Salary Deferral Option 
contributions begin within your first eligible pay period in 1998. There is 
no employer match in this Option.

During the course of the year, you may make an election that will allow you 
to increase your deferral percentage or stop your deferral entirely. This 
election must be made at least one full pay period in advance of the date 
when you want this change to become effective.

LIMITED BONUS DEFERRAL OPTION

This Option is available only to those United HealthCare executives who are 
eligible for special bonus amounts that are declared by United HealthCare's 
Board of Directors or Compensation Committee or their designees.

If you are eligible to make deferrals of special bonuses under the Limited 
Bonus Deferral Option, you will be notified in advance. At that time, you 
will receive an enrollment form. You may defer from 1 percent to 100 percent 
of any 1998 special bonuses before they are earned. 

MAKING CHANGES

Under the current tax laws, once your deferral election is made, it is 
irrevocable. However, you may increase or stop your deferral during the year 
under the Salary Deferral Option. Once the deferrals are suspended, they may 
not be resumed until the beginning of the next calendar year.

If you wish to increase or stop your payroll deductions, call the Plan 
Administrator at (612) 936-1653 to obtain the appropriate Executive Savings 
Plans form.

                                                                             5

INVESTING YOUR SAVINGS

You may elect to have your ESP deferrals and matching United HealthCare 
contributions credited with investment earnings from one or more of the four 
investment credit funds offered under the Plans.

These funds include the:

- - First American Prime Obligations Fund

- - Loomis Sayles Bond Fund

- - First American Equity Index Fund

- - PBHG Growth Fund

As you select your investment credit fund(s), keep in mind that your 
elections are subject to investment risk. As with any investment, if the 
returns credited on the fund(s) you choose are positive, your account balance 
will have positive credits. If the returns credited are negative, your 
account balance will decline. Remember, as unfunded plans, the investment 
credit funds are merely measuring tools to determine the value of your 
account under the Plans, and United HealthCare is not required to purchase 
such investments. Please review the fund information provided with your 
enrollment materials before making your decision.

If you make no investment credit election, you will receive credits as if you 
had elected the Loomis Sayles Bond Fund.

CHANGING YOUR INVESTMENT CHOICES

You may change your investment credit choices once per calendar quarter on 
any business day during that quarter. To make a change, you must complete and 
submit an Investment Credit Election Form to the Plan Administrator. If the 
form is received by the Plan Administrator by noon Central time, the change 
will become effective the following business day.

You also may elect to have your future contributions credited differently 
from your existing account balance for investment return purposes. When you 
make your investment election for 1998, it will not affect your existing 
account balance unless you actively elect to reallocate it. To reallocate your 
existing account balance, complete the Investment Credit Election Form.

MORE ABOUT YOUR INVESTMENT CREDIT CHOICES

You can elect to have your account credited with the investment performance 
of one or any combination of the following four funds:

- - FIRST AMERICAN PRIME OBLIGATIONS FUND. The fund's investment objective is 
  maximum current income to the extent consistent with the preservation of 
  capital and the maintenance of liquidity. The fund invests in money market 
  instruments including debt obligations issued by the U.S. government, its 
  agencies or instrumentalities, and corporate obligations including high-grade
  commercial paper, non-convertible corporate debt and loan participation 
  interests. The fund may also invest in repurchase agreements related to these
  securities.

- - LOOMIS SAYLES BOND FUND. The fund's investment objective is high total 
  investment return through a combination of current income and capital 
  appreciation. The fund seeks to attain its objective by normally investing 
  substantially all of its assets in debt securities (including convertibles), 
  although up to 20 percent of its assets may be invested in preferred stocks. 
  At least 65 percent of the fund's total assets may be invested in bonds. The 
  fund may invest any portion of its assets in securities of Canadian issuers, 
  and a limited portion of its assets in securities of other foreign issuers. 
  The fund will also invest less than 35 percent of its assets in securities of
  below investment grade quality.

- - FIRST AMERICAN EQUITY INDEX FUND. This fund seeks to achieve investment 
  results that correspond to the performance of the Standard and Poor's 500 
  Composite Stock Price Index (S&P 500). The fund invests substantially in 
  common stocks included in the S&P 500. The fund's advisor believes that its 
  objective can best be achieved by investing in the common stocks of 
  approximately 250 to 500 of the issues included in the S&P 500.

- - PBHG GROWTH FUND. The fund seeks capital appreciation and invests primarily 
  in common stocks of small and medium capitalization companies believed to 
  have an outlook for strong earnings growth and the potential for significant
  capital appreciation. The average market capitalizations or annual revenues 
  of holdings in the portfolio may fluctuate over time as a result of market 
  valuation levels and the availability of specific investment opportunities.

You may elect to have your accounts credited with investment performance in 
any combination of the investment credit funds in 1 percent increments, as 
long as your total investment percentage equals 100 percent. If you make no 
investment credit election, you will receive credits as if you had elected 
the Loomis Sayles Bond Fund.

RECEIVING INFORMATION ABOUT YOUR ACCOUNT

You will receive a statement, currently on a quarterly basis, showing the 
status of your account credits in the ESP. In addition, you have daily access 
to information about your account by calling the Retirement Plans Service 
Center at 1-888-842-2756.

                                                                           7

DISTRIBUTIONS FROM THE ESP

RECEIVING YOUR DISTRIBUTIONS

Distributions will be available only upon termination, permanent total 
disability or death. You can expect to receive your lump sum or first 
installment distribution beginning the February following the end of the 
calendar year in which the distribution event occurs. The distribution method 
is chosen upon your initial enrollment in the Plans and cannot be changed.

CHOOSING YOUR DISTRIBUTION METHOD

You have three distribution methods to choose from. The method you choose 
will be used for distributions for all four options in the Executive Savings 
Plans. If you do not elect a distribution option, you will automatically 
receive a lump sum payout of your account balance the February following the 
year of your termination, permanent total disability or death.

- - LUMP SUM: A single payment of your entire account balance is paid out to 
  you in February following the year in which you terminate, become disabled or 
  die. For example, if you terminate employment on January 12, 1998, you will 
  receive a single lump sum distribution in February 1999.

- - THREE-YEAR INSTALLMENTS: The three installments will be paid annually 
  beginning the February following the end of the calendar year in which you 
  terminate, become disabled or die. For example, if you terminate employment 
  on November 1, 1998, your installments will be paid in February 1999, 
  February 2000 and February 2001.

- - FIVE-YEAR INSTALLMENTS: The five installments are paid annually beginning 
  the February following the end of the calendar year in which you terminate, 
  become disabled or die. For example, if you terminate employment on April 25, 
  1998, your installments will be paid in February 1999, February 2000, 
  February 2001, February 2002 and February 2003.

WHAT TO DO NEXT

- - If you make a deferral election in the 401(k) Savings Plan, you will be 
  enrolled automatically in the Automatic Restoration Option at your then 
  current 401(k) Savings Plan deferral percentage. If you wish to "opt out" of
  this election, you must indicate so on a Deferral Election form.

- - Decide whether or not participating in one of the other ESP Options is 
  right for you. You may find it helpful to consult with a tax or financial 
  advisor. Then, if you decide to enroll, complete and return the appropriate 
  ESP election and beneficiary forms included in your packet. If you do not 
  designate a beneficiary, your benefits will be paid in accordance with the 
  Plan's provisions in the event of your death.

- - If you have questions, call the Plan Administrator at (612) 936-1645.

                                                                             9

IMPORTANT QUESTIONS AND ANSWERS ABOUT THE EXECUTIVE SAVINGS PLANS OPTIONS

Q1.  WHAT ARE THE DIFFERENCES BETWEEN THE EXECUTIVE SAVINGS PLANS AND THE 
     401(k) SAVINGS PLAN?

A1.  The United HealthCare 401(k) Savings Plan is a "qualified plan" under 
     the Internal Revenue Code. Under 401(k) plans, participants can defer 
     income into a trust fund, subject to certain limits. The chief limitations
     of 401(k) plans for executives are the various IRS-imposed caps on the 
     amount that can be deferred.

     Because the Executive Savings Plans apply only to a select group of 
     senior management and highly compensated employees and are not qualified 
     plans, these limitations do not apply. Non-qualified plans are more 
     flexible in their design and can be more selective in terms of the 
     employees who are allowed to participate.

     The main advantages of these Plans are the substantially greater 
     deferral opportunity they can offer, as well as the 50 cents per dollar 
     match on the first six percent of salary deferred in the Automatic 
     Restoration Option, or first six percent of MIP bonuses deferred into the 
     Incentive (MIP) Deferral Option. The main disadvantage is that the Plans 
     are not funded nor are assets held in a trust, but rather the account 
     balances are paid directly by United HealthCare out of its general assets.
     As a result, there is not the same security as in a qualified plan.

     Participation in the Executive Savings Plans does not affect your 
     ability to participate in the 401(k) Savings Plan. You can participate in 
     either or both Plans. However, you will be enrolled in the Executive 
     Savings Plans Automatic Restoration Option only if you are participating 
     in the 401(k) Savings Plan.

Q2.  WHAT ARE MY CHOICES FOR RECEIVING DISTRIBUTIONS FROM THE PLANS?

A2.  When you enroll in the Plans, you need to elect the form of payment you 
     wish to receive upon termination, death or disability:

     - One lump sum payment;

     - Annual installments over a three-year period; or

     - Annual installments over a five-year period.

     IF YOU DO NOT ELECT HOW YOU WANT YOUR ACCOUNT BALANCE DISTRIBUTED, IT 
     WILL BE PAID OUT IN ONE LUMP SUM PAYMENT THE FEBRUARY FOLLOWING THE YEAR OF
     YOUR TERMINATION, PERMANENT TOTAL DISABILITY OR DEATH. THE DISTRIBUTION
     METHOD YOU ELECT DURING YOUR INITIAL ENROLLMENT FOR ESP IS IRREVOCABLE. YOU
     CANNOT CHANGE YOUR DISTRIBUTION METHOD IN THE FUTURE.

10

<PAGE>

Q3.  WHY DO I HAVE TO MAKE A DEFERRAL ELECTION BEFORE I KNOW WHAT I WILL BE 
     PAID?

A3.  In exchange for the opportunity to defer taxation on unearned income, 
     the IRS requires that an irrevocable election to defer income must be made 
     before the income is actually earned. Since your election will remain in 
     effect for an entire year, you may want to be conservative in your deferral
     amount.

Q4.  WHAT WOULD HAPPEN TO MY DEFERRALS IN THE EVENT THAT UNITED HEALTHCARE 
     DECLARES BANKRUPTCY?

A4.  In the unlikely event that United HealthCare declares bankruptcy, ESP 
     participants would be viewed as general creditors and the claims for their 
     accounts would be treated in the manner and sequence stipulated by the 
     bankruptcy laws. Typically, ESP participants would share, on a pro-rata 
     basis with all other general unsecured creditors of the company, in any 
     assets that remain after payment of the company's obligations to secured 
     creditors. In contrast, benefits under the United HealthCare 401(k) Savings
     Plan would not be affected by the bankruptcy of United HealthCare since 
     they already are funded in trust.

Q5.  ARE DISTRIBUTIONS ELIGIBLE TO BE ROLLED OVER INTO AN IRA?

A5.  No. Because these are not IRS tax-qualified plans, you cannot roll over 
     your ESP distributions into an IRA or to another employer's qualified plan
     when you leave United HealthCare. When electing a non-qualified plan 
     distribution, we encourage you to seek professional tax advice to determine
     the best course of action for your individual financial circumstances.

Q6.  HOW DO I KNOW HOW WELL THE INVESTMENT CREDIT OPTIONS ARE PERFORMING?

A6.  You have daily access to your account and the performance of the 
     investment credit options by calling the Retirement Plans Service Center at
     1-888-842-2756. In addition, you will receive a statement of your account 
     balance (currently quarterly). The statement includes a chart showing the 
     investment credit performance of each of the fund options. Of course, past
     performance is not a guarantee of future performance.

                                                                           11

<PAGE>

Q7.  WHY AM I CREDITED WITH AN EMPLOYER MATCH CONTRIBUTION ON MY DEFERRALS 
     UNDER THE AUTOMATIC RESTORATION OPTION AND INCENTIVE (MIP) DEFERRAL OPTION,
     BUT NOT UNDER MY DEFERRALS FOR THE SALARY DEFERRAL OPTION?

A7.  The Automatic Restoration Option and the Incentive (MIP) Deferral Option 
     are intended to provide you with deferral and matching contribution 
     opportunities that are similar to what would be available to you under the
     401(k) Savings Plan, but which are not available to you because you are 
     prevented from making further 401(k) Savings Plan deferrals as a result 
     of reaching the 1998 $10,000 IRS deferral limit or the $160,000 
     compensation limit. The Salary Deferral Option is not designed or intended
     to "make up" for the 401(k) Savings Plan limitations, thus you are not 
     credited with an employer match on deferrals you make under this Option.

Q8.  CAN I CHANGE MY DISTRIBUTION ELECTION AFTER I BEGIN PARTICIPATING IN THE 
     PLANS?

A8.  No. Once your election has been made to defer funds into the Plans, the 
     IRS prevents you from exercising any control over the form or timing of 
     your distribution. This concept is referred to as "constructive receipt."

Q9.  IS THE EMPLOYER MATCH IN THE PLANS SUBJECT TO SOCIAL SECURITY (FICA) 
     AND/OR INCOME TAXES?

A9.  The employer match is subject to FICA tax at the time that the match is 
     credited to your ESP account. Whether the match is actually taxed depends
     on whether, at the time it is credited, you have exceeded the Social 
     Security taxable wage base. The match will always be subject to and taxed
     under the OASDI portion of the FICA tax. The match is not, however, subject
     to federal or state income taxes at the time it is credited to your 
     account. Instead, the match is generally subject to income tax when you 
     receive a distribution from the Plans.

        notice.

        3. BY EXECUTIVE.  Executive may terminate this Agreement and

        disability which renders Executive incapable of 

                                     -2-



<PAGE>


        performing Executive's duties, with or without reasonable 
        accommodation.  United HealthCare has the sole discretion to 
        determine whether Executive is permanently or totally disabled with 
        the meaning of this Section 3B4, and the effective date on which 
        Executive was rendered so disabled.

     C. EMPLOYEE BENEFITS.  On the effective date of the termination of this
     Agreement and Executive's employment by United HealthCare, Executive shall
     cease to be eligible for all employee benefit plans maintained by United
     HealthCare, except as required by federal or state continuation of coverage
     laws ("COBRA Benefits").  If Executive elects COBRA Benefits, Executive
     shall pay the entire cost of such benefits either through after-tax payroll
     deductions from the cash component of any severance compensation Executive
     receives or directly if Executive does not receive such severance
     compensation or if such severance compensation ceases.
     
     D. SEVERANCE EVENTS AND BENEFITS.  If a Severance Event, as hereinafter
     defined, occurs, Executive shall receive the severance benefits set forth
     in this Section 3D for a period of 12 months from the effective date of the
     applicable Severance Event (the "Severance Period").  For purposes of this
     Agreement a Severance Event shall occur if and when:

     (i)  United HealthCare (a) terminates this Agreement and Executive's
          employment without Cause, as hereinafter defined, or (b) terminates
          this Agreement without terminating Executive's employment and
          Executive elects to treat such termination of this Agreement as a
          Change in Employment, as hereinafter defined (collectively a
          "Termination without Cause"), or 
     
     (ii) Within two years following a Change in Control, as hereinafter
          defined, either (a) United HealthCare terminates this Agreement and
          Executive's employment without Cause, or (b) a Change in Employment
          occurs and Executive elects to treat such Change in Employment as a
          termination of Executive's employment (collectively a "Termination
          following a Change in Control"). 
     
     1. SEVERANCE COMPENSATION.  Executive shall receive the following severance
     compensation (the "Severance Compensation"):
     
          a) TERMINATION WITHOUT CAUSE.  Subject to Section 3D(1)(b) below, 
          upon a Termination without Cause Executive shall receive biweekly 
          payments equal to 1/26 of two times the sum of (1) Executive's 
          annualized base salary as of the date of the Severance Event, less 
          all applicable withholdings or deductions required by law and 
          Executive's COBRA Benefit payments, if any, plus (2) one-half of 
          the total of any bonus or incentive compensation paid or payable to 
          Executive for the two most recent calendar years (excluding any 
          special or one-time bonus or incentive compensation payments), 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 (excluding any special or 
          one-time bonus or incentive compensation payments). 

                                     -3-


<PAGE>


          b) TERMINATION FOLLOWING A CHANGE IN CONTROL.  Upon a Termination
          following a Change in Control, Executive shall receive biweekly
          payments equal to 1/26 of three times the sum of (1) Executive's
          highest annualized base salary during the 2 year period immediately
          preceding the Severance Event, less all applicable withholdings or
          deductions required by law and Executive's COBRA Benefit payments, if
          any, plus (2) the greater of (i) all bonuses that would be payable to
          Executive under any incentive compensation plans in which Executive
          then participates at Executive's then-current target level, or (ii)
          one-half of the total of any bonus or incentive compensation paid or
          payable to Executive for the two most recent calendar years (excluding
          any special or one-time bonus or incentive compensation payments), 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 (excluding any special or 
          one-time bonus or incentive compensation payments.  

     2. CASH PAYMENT.  Executive shall receive a one-time cash payment within a
     reasonable time following commencement of the Severance Period in an amount
     equal to the portion of the premiums that United HealthCare, or its
     affiliate or subsidiary, as applicable, subsidizes for employee-only
     health, dental and group term life benefit coverages (the "Cash Payment"). 
     The Cash Payment shall cover the Severance Period and shall be determined
     as of the effective date of the applicable Severance Event.
     
     3. JOB SEARCH FEES.  For a period not to exceed the Severance Period, 
     United HealthCare shall pay to an outplacement firm selected by United 
     HealthCare an amount deemed reasonable by United HealthCare for 
     outplacement and job search services for Executive.

     4. EXCISE TAX PAYMENT.  If any portion of the Severance Compensation 
     payable upon a Termination following a Change in Control constitutes an 
     Excess Parachute Payment, as hereinafter defined, such that an Excise 
     Tax, as hereinafter defined, is due, Executive shall receive a one-time 
     cash payment in an amount sufficient to cover (a) the full cost of the 
     Excise Tax plus (b) Executive's federal, state and city income, 
     employment and Excise Tax on this one-time cash payment and on all such 
     iterative payments so that Executive is made entirely whole for the 
     impact of the Excise Tax (collectively the "Gross-Up Payment").  United 
     HealthCare shall calculate these amounts on a timely and accurate basis, 
     and for this purpose Executive shall be deemed to be in the highest 
     marginal rate of federal, state and city taxes.  The Gross-Up Payment 
     shall be made within 30 days following the effective date of Executive's 
     employment termination.  For purposes of this Agreement the term "Excess 
     Parachute Payment" shall have the meaning set forth in Section 280G of 
     the Internal Revenue Code of 1986, as amended (the "Code").  For 
     purposes of this Agreement the term "Excise Tax" shall mean the tax 
     imposed on an Excess Parachute Payment pursuant to Sections 280G and 
     4999 of the Code.

This Section 3D shall be the sole liability of United HealthCare to Executive
upon the termination of this Agreement and Executive's employment hereunder, and
shall replace and be in lieu of any payments or benefits which otherwise might
be owed Executive under any other severance plan or program maintained by United
HealthCare.  Such compensation and benefits shall be conditioned on receipt by
United HealthCare of a separation agreement and a release of claims by Executive
on terms and conditions acceptable to United HealthCare in its sole discretion.

     E. DEFINITIONS AND PROCEDURES.  
     
        1. CAUSE.  For purposes of this Agreement "Cause" shall mean (a) the 
        refusal of Executive to follow the reasonable direction of the Board 
        of Directors of United HealthCare or Executive's supervisor or to 
        perform any duties reasonably required on material matters by United 
        HealthCare, (b) material violations of United HealthCare'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 
        United HealthCare.  Prior to the termination of Executive's 
        employment under subsection (a) of this definition of Cause, United 
        HealthCare shall provide Executive with a 30 day notice specifying 
        the basis for Cause.  If the Cause described in the notice is cured 
        to United HealthCare's reasonable satisfaction prior to the end of 
        the 30 day notice period, Executive's employment hereunder shall not 
        be terminated on that basis.  
     
        2. CHANGE IN CONTROL.  For purposes of this Agreement "Change in 
        Control" shall mean (a) the acquisition by any person, entity or 
        "group," within the meaning of Section 13(d)(3) or 14(d)(2) of the 
        Securities Exchange Act of 1934 (the "Exchange Act"), other than 
        United HealthCare or any employee benefit plan of United HealthCare, 
        of beneficial ownership (as defined in the Exchange Act) of 20% or 
        more of the common stock of UHC or the combined voting power of UHC's 
        then-outstanding voting securities in a transaction or series of 
        transactions not approved in advanced by a vote of at least 
        three-quarters of the directors of UHC; (b) a change in 50% or more 
        of the directors of UHC in any 12 month period; (c) the approval by 
        the shareholders of UHC of a reorganization, merger, consolidation, 
        liquidation or dissolution of UHC or of the sale (in one transaction 
        or a series of related transactions) of all or substantially all of 
        the assets of UHC other than a reorganization, merger, consolidation, 
        liquidation, dissolution or sale approved in advance by a vote of at 
        least three-quarters of the directors; (d) the first purchase under 
        any tender offer or exchange offer (other than an offer by UHC) 
        pursuant to which shares of UHC common stock are purchased; or (e) at 
        least a majority of the directors of UHC determine in their sole 
        discretion that there has been a change of control of UHC.  

        3. CHANGE IN EMPLOYMENT.  For purposes of this Agreement a "Change in 
        Employment" shall be deemed to have occurred (a) if (i) Executive's 
        duties are materially and adversely changed without Executive's prior 
        consent, (ii) Executive's salary or benefits are reduced other than 
        as a general reduction of salaries and 

                                     -5-



<PAGE>

benefits by United HealthCare, (iii) without terminating Executive's 
        employment United HealthCare terminates this Agreement, or (iv) the 
        geographic location for the performance of Executive's duties 
        hereunder is moved more than 50 miles from the geographic location at 
        the Effective Date without Executive's prior consent, and (b) if in 
        each case under subsections (a) (i), (ii), (iii) and (iv), in the 
        period beginning 90 days before the time the Change in Employment 
        occurs, Cause does not exist or if Cause does exist United HealthCare 
        has not given Executive written notice that Cause exists. 
        Notwithstanding the foregoing, an isolated, insubstantial or 
        inadvertent action by United HealthCare, which is remedied by United 
        HealthCare within 30 days after receipt of notice thereof by 
        Executive, shall not constitute a Change in Employment.  Executive 
        may elect to treat a Change in Employment as a termination of this 
        Agreement and Executive's employment hereunder.  To do so Executive 
        shall send written notice of such election to United HealthCare 
        within 90 days after the date Executive receives notice from United 
        HealthCare 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 90 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 
        United HealthCare receives the written notice of election.

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

     A. UNITED HEALTHCARE'S PROPERTY.

        1. ASSIGNMENT OF PROPERTY RIGHTS.  Executive shall promptly disclose

        jointly with another person, group or entity, whether during the 
        normal hours of employment at United HealthCare 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 United 
        HealthCare.  Executive shall give United HealthCare any assistance it

        equipment, supplies, facility or trade secret information of United 
        HealthCare was used and which was developed entirely on the 
        Executive's own time and which (1) does not relate to the business of 
        United HealthCare or to United HealthCare's anticipated research or 
        development, or (2) does not result from any work performed by the 
        Executive for United HealthCare.

        2. NO REMOVAL OF PROPERTY. Executive shall not remove any records, 
        documents, or any other tangible items (excluding Executive's

     potential customers and suppliers.  United HealthCare 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

     HealthCare, or those associated with United HealthCare, in any way, 
     whether orally, in writing or otherwise, directly or by implication in

     applicable (iii) any period following the termination or expiration of this
     Agreement during which Executive remains employed by United HealthCare and
     (iv) for a period of one year after the last day of the latest of any

     party, except that United HealthCare in its sole discretion may assign this
     Agreement to an entity controlled by United HealthCare at the time of the
     assignment.  If United HealthCare subsequently loses or gives up control of
     the entity to which this Agreement is assigned, such entity shall become
     United HealthCare for all purposes under this Agreement, beginning on the
     date on which United HealthCare loses or gives up control of the entity.

     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 the 
     Executive and United HealthCare.
     
     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

     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 
     Executive has received adequate consideration from United HealthCare to 
     enter into this Agreement.

     United HealthCare' Employment  Arbitration Policy.  The arbitrators 
     shall not ignore or vary the terms of this Agreement and shall be bound 
     by and apply controlling law.  The parties acknowledge that Executive's 
     failure to comply with the Confidential Information, Non-Solicitation 
     and Non-Competition provisions of this Agreement will cause immediate 
     and irreparable injury to United HealthCare 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.

     H. 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.

THIS AGREEMENT CONTAINS A BINDING ARBITRATION PROVISION THAT MAY BE ENFORCED BY

This memorandum of understanding, effective as of October 16, 1998, supplements
and amends the employment agreement, effective as of October 16, 1998, between
Jeannine Rivet and United HealthCare Services, Inc.  as set forth below.

          1. The parties agree that Section 3(D)(i) is amended in its entirety 
             to read:

               United HealthCare (a) terminates this Agreement and Executive's
               employment without Cause, as hereinafter defined, or (b) a Change
               in Employment, as hereinafter defined occurs (collectively a
               "Termination without Cause"), or
          
          2. The parties confirm that a change in responsibility, in and of 
             itself will not constitute a Change in Employment, acknowledging 
             that so long as Executive retains senior executive level 
             functional, administrative, or operational responsibility no 
             Change of Employment shall have occurred solely as a result of 
             such change in responsibility or title.

          3. For purposes of the non-competition provisions of Section 4(E), 
             the parties concur that employment in the health care industry 
             is not absolutely prohibited by Section 4(E), it being the 
             intent of the parties in Section 4 (E) to limit Executive's 
             future employment by managed care, health care insurance, 
             physician management, or other, similar type of organization.

          4. The references in Section 4(E) to "24 months" are amended to 
             read "12 months."

     In all other respects the parties reaffirm and agree to be bound by the
provisions of the Employment Agreement, effective as of the date set forth
above.

     This Agreement, effective as of October 16, 1998 (the "Effective Date"), 
is made by and between David J. Lubben ("Executive") and United HealthCare 
Services, Inc. ("United HealthCare") for the purpose of setting forth the

affiliate or subsidiary of United HealthCare, and to protect United 
HealthCare's knowledge, expertise, customer relationships and the 
confidential information United HealthCare has developed about its customers, 
products, operations and services.  Unless the context otherwise requires, 
when used in this Agreement "United HealthCare" includes any entity 
affiliated with United HealthCare. 

     WHEREAS, as additional consideration for entering into this Agreement
Executive shall receive, upon execution of this Agreement, a nonqualified stock
option to purchase 50,000 shares of United HealthCare Corporation ("UHC") common

     performance of Executive's duties in a diligent and proper manner.  

     C. TERMINATION OF PRIOR AGREEMENTS.  As of the Effective Date all other 
     prior employment related agreements between Executive and United

     shall receive a periodic performance review and consideration for an 
     increase in the Initial Base Salary.
     
     B. BONUS AND STOCK PLANS.  Executive shall be eligible to participate in 
     the incentive compensation plans and the stock option and grant plans

     any life, health, dental, short-term and long-term disability insurance

     HealthCare and in accordance with the terms and conditions of those plans
     and applicable laws and regulations.

<PAGE>


        4. DEATH, DISABILITY, ETC.  This Agreement and Executive's employment 
        by United HealthCare shall terminate immediately upon Executive's 
        death.  This Agreement and Executive's employment hereunder shall 
        automatically terminate in the event of a permanent and total 
        disability which renders Executive incapable of performing 
        Executive's duties, with or without reasonable accommodation.  United 
        HealthCare has the sole discretion to determine whether Executive is 
        permanently or totally disabled with the meaning of this Section 3B4, 
        and the effective date on which Executive was rendered so disabled.

     C. EMPLOYEE BENEFITS.  On the effective date of the termination of this
     Agreement and Executive's employment by United HealthCare, Executive shall
     cease to be eligible for all employee benefit plans maintained by United
     HealthCare, except as required by federal or state continuation of coverage
     laws ("COBRA Benefits").  If Executive elects COBRA Benefits, Executive
     shall pay the entire cost of such benefits either through after-tax payroll
     deductions from the cash component of any severance compensation Executive
     receives or directly if Executive does not receive such severance
     compensation or if such severance compensation ceases.
     
     D. SEVERANCE EVENTS AND BENEFITS.  If a Severance Event, as hereinafter
     defined, occurs, Executive shall receive the severance benefits set forth
     in this Section 3D for a period of 12 months from the effective date of the
     applicable Severance Event (the "Severance Period").  For purposes of this
     Agreement a Severance Event shall occur if and when:

     (i)  United HealthCare (a) terminates this Agreement and Executive's
          employment without Cause, as hereinafter defined, or (b) terminates
          this Agreement without terminating Executive's employment and
          Executive elects to treat such termination of this Agreement as a
          Change in Employment, as hereinafter defined (collectively a
          "Termination without Cause"), or 
     
     (ii) Within two years following a Change in Control, as hereinafter
          defined, either (a) United HealthCare terminates this Agreement and
          Executive's employment without Cause, or (b) a Change in Employment
          occurs and Executive elects to treat such Change in Employment as a
          termination of Executive's employment (collectively a "Termination
          following a Change in Control"). 
     
     1. SEVERANCE COMPENSATION.  Executive shall receive the following severance
     compensation (the "Severance Compensation"):
     
          a) TERMINATION WITHOUT CAUSE.  Subject to Section 3D(1)(b) below, 
          upon a Termination without Cause Executive shall receive biweekly 
          payments equal to 1/26 of two times the sum of (1) Executive's 
          annualized base salary as of the date of the Severance Event, less 
          all applicable withholdings or deductions required by law and 
          Executive's COBRA Benefit 

                                     -3-


<PAGE>


          payments, if any, plus (2) one-half of the total of any bonus or 
          incentive compensation paid or payable to Executive for the two 
          most recent calendar years (excluding any special or one-time bonus 
          or incentive compensation payments), 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 (excluding any special or one-time bonus or incentive 
          compensation payments). 
          
          b) TERMINATION FOLLOWING A CHANGE IN CONTROL.  Upon a Termination
          following a Change in Control, Executive shall receive biweekly
          payments equal to 1/26 of three times the sum of (1) Executive's
          highest annualized base salary during the 2 year period immediately
          preceding the Severance Event, less all applicable withholdings or
          deductions required by law and Executive's COBRA Benefit payments, if
          any, plus (2) the greater of (i) all bonuses that would be payable to
          Executive under any incentive compensation plans in which Executive
          then participates at Executive's then-current target level, or (ii)
          one-half of the total of any bonus or incentive compensation paid or
          payable to Executive for the two most recent calendar years (excluding
          any special or one-time bonus or incentive compensation payments), 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 (excluding any special or 
          one-time bonus or incentive compensation payments.  

     2. CASH PAYMENT.  Executive shall receive a one-time cash payment within a
     reasonable time following commencement of the Severance Period in an amount
     equal to the portion of the premiums that United HealthCare, or its
     affiliate or subsidiary, as applicable, subsidizes for employee-only
     health, dental and group term life benefit coverages (the "Cash Payment"). 
     The Cash Payment shall cover the Severance Period and shall be determined
     as of the effective date of the applicable Severance Event.
     
     3. JOB SEARCH FEES.  For a period not to exceed the Severance Period, 
     United HealthCare shall pay to an outplacement firm selected by United 
     HealthCare an amount deemed reasonable by United HealthCare for 
     outplacement and job search services for Executive.

     4. EXCISE TAX PAYMENT.  If any portion of the Severance Compensation 
     payable upon a Termination following a Change in Control constitutes an 
     Excess Parachute Payment, as hereinafter defined, such that an Excise 
     Tax, as hereinafter defined, is due, Executive shall receive a one-time 
     cash payment in an amount sufficient to cover (a) the full cost of the 
     Excise Tax plus (b) Executive's federal, state and city income, 
     employment and Excise Tax on this one-time cash payment and on all such 
     iterative payments so that Executive is made entirely 

                                     -4-




<PAGE>

     whole for the impact of the Excise Tax (collectively the "Gross-Up 
     Payment").  United HealthCare shall calculate these amounts on a timely 
     and accurate basis, and for this purpose Executive shall be deemed to be 
     in the highest marginal rate of federal, state and city taxes.  The 
     Gross-Up Payment shall be made within 30 days following the effective 
     date of Executive's employment termination.  For purposes of this 
     Agreement the term "Excess Parachute Payment" shall have the meaning set 
     forth in Section 280G of the Internal Revenue Code of 1986, as amended 
     (the "Code").  For purposes of this Agreement the term "Excise Tax" 
     shall mean the tax imposed on an Excess Parachute Payment pursuant to 
     Sections 280G and 4999 of the Code.

This Section 3D shall be the sole liability of United HealthCare to Executive
upon the termination of this Agreement and Executive's employment hereunder, and
shall replace and be in lieu of any payments or benefits which otherwise might
be owed Executive under any other severance plan or program maintained by United
HealthCare.  Such compensation and benefits shall be conditioned on receipt by
United HealthCare of a separation agreement and a release of claims by Executive
on terms and conditions acceptable to United HealthCare in its sole discretion.

     E. DEFINITIONS AND PROCEDURES.  
     
     1. CAUSE.  For purposes of this Agreement "Cause" shall mean (a) the 
     refusal of Executive to follow the reasonable direction of the Board of 
     Directors of United HealthCare or Executive's supervisor or to perform 
     any duties reasonably required on material matters by United HealthCare, 
     (b) material violations of United HealthCare'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 United 
     HealthCare.  Prior to the termination of Executive's employment under 
     subsection (a) of this definition of Cause, United HealthCare shall 
     provide Executive with a 30 day notice specifying the basis for Cause.  
     If the Cause described in the notice is cured to United HealthCare's 
     reasonable satisfaction prior to the end of the 30 day notice period, 
     Executive's employment hereunder shall not be terminated on that basis.  
     
     2. CHANGE IN CONTROL.  For purposes of this Agreement "Change in Control"
     shall mean (a) the acquisition by any person, entity or "group," within the
     meaning of Section 13(d)(3) or 14(d)(2) of the Securities Exchange Act of
     1934 (the "Exchange Act"), other than United HealthCare or any employee
     benefit plan of United HealthCare, of beneficial ownership (as defined in
     the Exchange Act) of 20% or more of the common stock of UHC or the combined
     voting power of UHC's then-outstanding voting securities in a transaction
     or series of transactions not approved in advanced by a vote of at least
     three-quarters of the directors of UHC; (b) a change in 50% or more of the
     directors of UHC in any 12 month period; (c) the approval by the
     shareholders of UHC of a reorganization, merger, 

                                     -5-



<PAGE>

     consolidation, liquidation or dissolution of UHC or of the sale (in one 
     transaction or a series of related transactions) of all or substantially 
     all of the assets of UHC other than a reorganization, merger, 
     consolidation, liquidation, dissolution or sale approved in advance by a 
     vote of at least three-quarters of the directors; (d) the first purchase 
     under any tender offer or exchange offer (other than an offer by UHC) 
     pursuant to which shares of UHC common stock are purchased; or (e) at 
     least a majority of the directors of UHC determine in their sole 
     discretion that there has been a change of control of UHC.  

     3. CHANGE IN EMPLOYMENT.  For purposes of this Agreement a "Change in
     Employment" shall be deemed to have occurred (a) if (i) Executive's duties
     are materially and adversely changed without Executive's prior consent,
     (ii) Executive's salary or benefits are reduced other than as a general
     reduction of salaries and benefits by United HealthCare, (iii) without
     terminating Executive's employment United HealthCare terminates this
     Agreement, or (iv) the geographic location for the performance of
     Executive's duties hereunder is moved more than 50 miles from the
     geographic location at the Effective Date without Executive's prior
     consent, and (b) if in each case under subsections (a) (i), (ii), (iii) and
     (iv), in the period beginning 90 days before the time the Change in
     Employment occurs, Cause does not exist or if Cause does exist United
     HealthCare has not given Executive written notice that Cause exists. 
     Notwithstanding the foregoing, an isolated, insubstantial or inadvertent
     action by United HealthCare, which is remedied by United HealthCare within
     30 days after receipt of notice thereof by Executive, shall not constitute
     a Change in Employment.  Executive may elect to treat a Change in
     Employment as a termination of this Agreement and Executive's employment
     hereunder.  To do so Executive shall send written notice of such election
     to United HealthCare within 90 days after the date Executive receives
     notice from United HealthCare 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 90 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 United HealthCare receives the
     written notice of election.

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

     A. UNITED HEALTHCARE'S PROPERTY.

        1. ASSIGNMENT OF PROPERTY RIGHTS.  Executive shall promptly disclose 
        to United HealthCare in writing all inventions, discoveries and works 
        of authorship, whether or not patentable or copyrightable, which are 
        conceived, made, discovered, written 

                                     -6-


<PAGE>


        or created by Executive alone or jointly with another person, group 
        or entity, whether during the normal hours of employment at United 
        HealthCare 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 United HealthCare.  Executive shall give 
        United HealthCare any assistance it reasonably requires in order for 
        United HealthCare to perfect, protect, and use its rights to 
        inventions and works of authorship. 
     
        This provision shall not apply to an invention for which no 
        equipment, supplies, facility or trade secret information of United 
        HealthCare was used and which was developed entirely on the 
        Executive's own time and which (1) does not relate to the business of 
        United HealthCare or to United HealthCare's anticipated research or 
        development, or (2) does not result from any work performed by the 
        Executive for United HealthCare.
     
        2. NO REMOVAL OF PROPERTY. Executive shall not remove any records, 
        documents, or any other tangible items (excluding Executive's 
        personal property) from the premises of United HealthCare in either 
        original or duplicate form, except as is needed in the ordinary 
        course of conducting business for United HealthCare.
     
        3. RETURN OF PROPERTY.  Executive shall immediately deliver to United 
        HealthCare, upon termination of employment with United HealthCare, or 
        at any other time upon United HealthCare'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 employment Executive 
     will develop, become aware of and accumulate expertise, knowledge and 
     information regarding United HealthCare's organization, strategies, 
     business and operations and United HealthCare's past, current or 
     potential customers and suppliers.  United HealthCare 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 United HealthCare or as has been 
     expressly permitted in writing by United HealthCare. This Section 4B 
     shall survive the termination of this Agreement.

     C. NON-DISPARAGEMENT.  Executive agrees that he will not criticize, make 
     any negative comments or otherwise disparage or put in disrepute United 
     HealthCare, or those associated with United HealthCare, in any way, 
     whether orally, in writing or otherwise, directly or by implication in 
     communication with any person, including but not limited to 

                                     -7-

<PAGE>

     customers or agents of United HealthCare.  This Section 4C shall survive 
     the termination of this Agreement.

     D. NON-SOLICITATION.  During (i) the term of this Agreement, (ii) the
     Severance Period or any period in which Executive receives severance
     compensation pursuant to United HealthCare' election under Section 4E, as
     applicable (iii) any period following the termination or expiration of this
     Agreement during which Executive remains employed by United HealthCare and
     (iv) for a period of one year after the last day of the latest of any
     period described in (i), (ii) or (iii), Executive shall not (y) directly or
     indirectly attempt to hire away any then-current employee of United
     HealthCare or a subsidiary of United HealthCare or to persuade any such
     employee to leave employment with United HealthCare, or (z)  directly or
     indirectly solicit, divert, or take away, or attempt to solicit, divert, or

     in which United HealthCare has a more than 20% equity interest) has
     established or is actively seeking to establish a business or customer
     relationship.  This Section 4D shall survive the termination of this
     Agreement.

5. MISCELLANEOUS.

     Agreement to an entity controlled by United HealthCare at the time of the
     assignment.  If United HealthCare subsequently loses or gives up control of
     the entity to which this Agreement is assigned, such entity shall become
     United HealthCare for all purposes under this Agreement, beginning on the
     date on which United HealthCare loses or gives up control of the entity. 
     Any successor to United HealthCare shall be deemed to be United HealthCare
     for all purposes of this Agreement.

     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

     remedy.

     Executive has received adequate consideration from United HealthCare to

     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.

     H. NO THIRD-PARTY BENEFICIARIES.  This Agreement shall not confer or be

                          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 

<PAGE>

     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

<PAGE>

     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

     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

     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.

     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,

EXHIBIT A

                                 EMPLOYMENT AGREEMENT

  This Agreement is made by and between David Koppe ("Employee") 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 Employee'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 Employee and UHS or any subsidiary or affiliate of UHS but
does not supersede the Release Agreements that UHS and I execute.

1.      EMPLOYMENT AND DUTIES.

        A.      EMPLOYMENT.  UHS hereby directly or through its subsidiaries
                employs Employee.  Employee 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.  Employee shall perform such duties as are commonly
                associated with his/her position or as are reasonably assigned
                to Employee by his/her supervisor from time-to-time.  Employee
                acknowledges that he will not be employed as Chief Financial
                Officer effective July 1, 1998. After that date, Employee will
                provide services to UHS regarding financial and other related
                issues as requested by senior management on a flexible work
                schedule to be mutually determined by Employee and the Senior
                Executive Vice-President. Employee shall be generally available
                to senior management during regular business hours and shall
                remain classified as a full-time employee. 

2.      COMPENSATION.

        A.      BASE SALARY.  Employee shall be paid a base annual salary in the
                amount of $367,500 payable bi-weekly, less all applicable
                withholdings and deductions.

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

        C.      MIP AND LTIP PAYMENTS.  UHS also agrees to pay Employee pursuant
                to the Long Term Incentive Plan ("LTIP") for the 1997-1998 cycle
                according to the terms of the plan and continue Employee's
                eligibility for the MIP for 1998 according to the terms of the
                plan.  This MIP payment will be made pursuant to the terms of
                the Plan but no later than March, 1999. Employee's MIP payment
                for 1998 will be at least one-half Employee's target under the
                MIP. 

        D.      STOCK OPTION VESTING. For the period December 1, 1998 through
                September 30, 1999, UHS also agrees to vest Employee's United
                HealthCare performance based stock option grants in the
                following manner: (1) for grants made before July 1, 1996, UHS
                agrees to vest the grants at a rate of 20% of the number of
                shares covered by the option or grant on the anniversary date of
                the option or grant; (2) for grants or options made after July
                1, 1996, UHS agrees to vest  the grant at a rate of  25% of the
                number of shares covered by the grant on the anniversary date of
                the option or grant. 

        E.      OTHER BENEFITS.  Employer shall continue provide Employee with
                the same employee benefit coverages that it is currently
                providing to Employee subject to his elections.  Employer agrees
                to provide Employee with use of UHS' voice-mail and computer 
                e-mail.

3.      TERM AND TERMINATION.

        A.      TERM.  The term of this Agreement shall begin on July 1, 1998
                (the "Effective Date") and shall continue until the earlier of 
                the date of termination pursuant to Section 3B or September 30,
                1999.

        B.      TERMINATION OF AGREEMENT AND/OR EMPLOYMENT.

                i.      This Agreement may be terminated at any time by the
                        mutual written agreement of the parties.
                        
                ii.     UHS may terminate Employee's employment or terminate
                        this Agreement for Cause (as defined below) by giving
                        written notice of termination which is received by
                        Employee at least 30 days before the effective date of
                        termination of employment or of this Agreement, as the
                        case may be.  UHS will specify the reasons for the
                        termination and provide Employee with the reasonable
                        opportunity to respond to the reasons stated.  If
                        Employee has not adequately resolved the issue that gave
                        rise to the termination, the termination will become
                        effective on the date specified by UHS. 
                        
                iii.    Employee may terminate his/her 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. 
                        
                iv.     This Agreement shall automatically terminate on the
                        effective date of the termination of Employee's
                        employment or on the date of Employee's death,
                        retirement or permanent and total disability which
                        renders Employee incapable of performing Employee's
                        duties; provided, however, notwithstanding such
                        termination, (i) in the event of Employee's death, UHS
                        shall continue to pay to Employee or his estate or
                        representative the base salary scheduled to be made in
                        accordance with Section 2A of this Agreement through
                        September 30, 1999; (ii) in the event of Employee's
                        permanent and total disability, UHS will continue to pay
                        Employee the difference between his base salary and any
                        disability payments that Employee receives through
                        September 30, 1999; and (iii) in the event of Employee's
                        death or permanent and total disability, UHS will vest
                        all of Employee's stock options, will provide the health
                        coverage to the extent applicable to Employee's family
                        members and pursuant to the terms of the post career
                        coverage program included in the attached second
                        release, and will allow Employee's estate, personal
                        representative or heirs to have the extended stock
                        option exercise date (September 30, 2002) included in
                        the attached second release. UHS has the sole right, in
                        its reasonable discretion, to determine whether Employee
                        is permanently or totally disabled within the meaning of
                        this Section 3B4. 
                
4.      SEVERANCE EVENTS AND COMPENSATION. 
        
        A.      In the event Employee's employment with UHS is terminated by UHS
                pursuant to Section 3B(ii) with Cause, then:
                
                i.      This Agreement shall also be terminated along with all
                        future payments, stock vesting and benefits described in
                        this Agreement. UHS will not execute the Second Release
                        attached to this Agreement. 

                ii.     As of the effective date of termination of employment,
                        Employee shall cease to be eligible for all benefit
                        plans maintained by UHS, except as required by federal
                        or state continuation of coverage laws.

        B.      In the event Employee's employment with UHS is terminated by
                Employee pursuant to Section 3B(iii), then:
        
                i.      This Agreement shall also be terminated.  However, UHS
                        shall continue to pay Employee his bi-weekly base
                        salary, less withholdings and deductions, through
                        September 30, 1999. As of the effective date of
                        termination, however, Employee shall not receive any
                        future stock vesting, LTIP or MIP Payments described in
                        this Agreement. 
                ii.     UHS will execute the Second Release attached to this
                        Agreement within 21 days of Employee's termination of
                        employment. 

        C.      Definitions and Procedure.  

                i.      For purposes of this Agreement, "Cause" shall mean the
                        (a) the willful failure or refusal of Employee to follow
                        the reasonable directions of UHS's Board of Directors or
                        Employee's supervisor or to perform any duties
                        reasonably required by UHS, (b) a failure to adequately
                        meet reasonable performance expectations, (c) material
                        violations of UHS's Code of Conduct or (d) the
                        commission of any criminal act or act of fraud or
                        dishonesty by Employee in connection with Employee's
                        employment by UHS.  In the event that UHS terminates
                        Employee's employment under subsections (a), (b) or (c)
                        of this Cause definition, UHS shall specify in the
                        notice of termination 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, the notice of termination of employment shall be
                        withdrawn.  

                
5.      PROPERTY RIGHTS, CONFIDENTIALITY, NON-SOLICIT AND NON-COMPETE
        PROVISIONS.

        A.      UHS'S PROPERTY.

                i.      Except for inventions, discoveries or works referred to
                        in the next paragraph, Employee 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 Employee alone or jointly with
                        another person, group or entity, whether during the
                        normal hours of employment at UHS or on Employee's own
                        time, during the term of this Agreement.  Employee
                        assigns all rights to all such inventions and works of
                        authorship to UHS.  Employee 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.  

                        This provision shall not apply to an invention,
                        discovery or work for which no equipment, supplies,
                        facility or trade secret information of UHS was used and
                        which was developed entirely on the Employee'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 Employee
                        for UHS.

                ii.     Employee shall not remove any records, documents, or any
                        other tangible items (excluding Employee'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.

                iii.    Employee 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 Employee's personal
                        property) in Employee's possession or 

                                       3

                        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.  UHS agrees 
                        that Employee can purchase his personal computer from 
                        UHS at the depreciated value, according to the Company's
                        records.

        B.      CONFIDENTIAL INFORMATION.  During the course of his employment
                Employee 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 Employee shall not
                use such Confidential Information or disclose it to other
                persons or entities except as is necessary for the performance
                of Employee's duties for UHS or as has been expressly permitted
                in writing by UHS unless such information is available to the
                public at the time of its disclosure by Employee in which case
                such information is no longer Confidential Information.

        C.      NON-SOLICITATION.  During (i) the term of this Agreement, (ii)
                any period for which Employee is receiving payments under
                Section 4B of this Agreement, (iii) any period following the
                termination or expiration of this Agreement during which
                Employee remains employed by UHS and (iv) for a period of one
                year after the last day of the latest of any period described in
                (i), (ii) or (iii), Employee 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, in each case, on the date
                hereof.

        D.      NON-COMPETITION.  During (i) the term of this Agreement, (ii)
                any period for which Employee is receiving payments under
                Section 4B of this Agreement, and (iii) any period following the
                termination or expiration of this Agreement during which
                Employee remains employed by UHS, Employee shall not, without
                UHS's prior written consent, 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 (including any subsidiary or affiliated company in which UHS
                currently has a more than 20% equity interest) is engaged on the
                date hereof.  Notwithstanding anything contained in this Section
                4D, after (i), (ii), and (iii) above, Employee may become
                employed by or consult with (i) any hospital, physician or other
                medical group excluding for these purposes any HMO, PPO,
                physician practice management type company, or similar entity
                controlled by such hospital, physician, or medical group, (ii)
                any medical device or supply company, (iii) any securities or
                venture capital firm, money management entity, or (iv)
                consulting firm even if the firm provides consulting services in
                the health care area (provided that employee does not provide
                any services in the health care or health care management area),
                or (v) to any pharmaceutical company or pharmacy benefits
                company.   

6.      MISCELLANEOUS.

        A.      ASSIGNMENT.  This Agreement shall be binding upon and shall
                inure 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.

                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.

                        UHS:            300 Opus Center
                                        9900 Bren Road East
                                        Minnetonka, MN 55343
                                        Attn: Senior Vice President Human
                                        Resources

                        Employee:       




        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 the
                Employee 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 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.  Employee acknowledges and agrees
                that he has received adequate consideration from UHS to enter
                into this Agreement.

        G.      DISPUTE RESOLUTION AND REMEDIES.  Any dispute arising between
                the parties relating to this Agreement or to Employee's
                employment by UHS shall be resolved by binding arbitration
                pursuant to UHS's Employment Arbitration Policy.  In no event
                may the arbitration be initiated more than one year after the
                date one party first gave written notice of the dispute to the
                other party.  The parties acknowledge that Employee'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.

        H.      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.
        
        I.      SECOND RELEASE.  UHS and Employee agree to execute the second
                release within 21 days of employee's termination from employment
                unless Employee is terminated of employment for Cause, as
                defined in Section 4C of this Agreement.
