(2)  Estimated solely for purposes of calculating the registration fee required
     by Section 6(b) of the Securities Act of 1933, as amended (the "Securities
     Act"). This fee has been computed pursuant to Rule 457(f)(2). Because
     there is no market for the shares of VPN common stock to be cancelled in
     connection with the Acquisition and VPN has an accumulated capital deficit
     at December 31, 2000, the fee is computed based on one-third of the par
     value of the maximum number of shares of common stock of VPN outstanding
     immediately before the Acquisition, assuming the exercise of all
     outstanding options (2,327,092 shares). The par value of VPN common stock
     is $0.01 per share.
   The registrant hereby amends this registration statement on such date or
dates as may be necessary to delay its effective date until the registrant
shall file a further amendment that specifically states that this registration
statement shall thereafter become effective in accordance with Section 8(a) of
the Securities Act or until this registration statement shall become effective
on such date as the Commission, acting pursuant to such Section 8(a), may
determine.

                          NOTICE OF SPECIAL MEETING on
                             , 2001 and PROXY STATEMENT

Dear Fellow Shareholder:

   On behalf of the Board of Directors, you are cordially invited to attend a
Special Meeting of the Shareholders of Virginia's Physician Network, Inc. (VPN)
at           a.m. local time on            , 2001, at                  .

   A proposal to be considered at this important meeting, if approved, will
conclude the transactions contemplated by agreements with United Healthcare
Services, Inc. that were approved by VPN Shareholders in October 1999. The
proposal involves the approval of (a) the sale of substantially all of VPN's
assets to a subsidiary of UnitedHealth Group Incorporated (UnitedHealth Group)
in exchange for shares of UnitedHealth Group common stock that will be
distributed to VPN shareholders and for the resolution of certain contested
monetary obligations of VPN to a subsidiary of UnitedHealth Group, and (b) the
subsequent dissolution and termination of VPN.

   At a meeting on December 28, 2000, VPN's Board of Directors unanimously
voted to exercise its put of VPN's shares in United Healthcare of Virginia,
Inc., an HMO organized by VPN and a subsidiary of UnitedHealth Group in 1996,
and to execute the Asset Acquisition Agreement that memorializes this proposal.
The VPN Board of Directors recommends that you vote FOR this proposal. Approval
of the proposal requires a "FOR" vote from more than two-thirds of the votes
entitled to be cast by VPN Shareholders at the Special Meeting. Unless this
proposal is approved, the value of your investment in VPN may be adversely
impacted.

   Every vote FOR the proposal is important. Your vote is important. If you
don't return the enclosed proxy or if you vote by checking the ABSTAIN box on
it, the effect is a vote AGAINST the proposal. Even if you plan to attend the
Special Meeting of Shareholders, you should complete, date and sign the
enclosed proxy and return it to VPN immediately by faxing it to (804) 771-5625
or by mailing it in the pre-addressed, postage paid envelope enclosed. If you
do attend the meeting, you may vote in person, whether or not you have mailed
your proxy. A proxy may be revoked at any time before it is voted.

   VPN's Board of Directors is pleased that shareholders will have a positive
return on their initial investment, if this proposal is approved. More
importantly, many of VPN's original objectives have been achieved in the
organization and operation of UnitedHealthcare of Virginia. Many VPN
shareholders serve on its various guidance and oversight committees. VPN
encourages its shareholders to continue to play a vital role in the management
of the health plan by remaining participating physicians in the
UnitedHealthcare network and serving on UnitedHealthcare of Virginia's guidance
and oversight committees. UnitedHealthcare of Virginia promotes an open access,
no referral product which substantially reduces administrative hassle for
patients and physicians when compared to typical HMOs. UnitedHealthcare's Care
Coordination(TM) approach facilitates coverage and benefits administration
between the patient and physician and gives the physician full decision-making
authority in medical necessity judgements.

   The formal meeting Notice and Proxy Statement for the Special Meeting are
enclosed. Please take time to consider the enclosed material carefully. Thank
you for your cooperation and interest in having your shares represented at this
important Special Meeting of Shareholders.

                                          Sincerely,

                                          C. Gregory Lockhart, M.D.
                                          Chairman of the Board, President and
                                           C.E.O.

P.S.  This is a very important meeting. The proposal being considered may
      impact your investment in VPN and any profit you may make on that
      investment.

The Companies

Virginia's Physician Network, Inc.

   Post Office Box 500
   Richmond, Virginia 23218-0500
   Attention: K. Marshall Cook, Esq.
   (804) 771-5641

   Virginia's Physician Network (VPN) was organized as a 100% physician-owned,
statewide network of physicians and incorporated in Virginia on August 9, 1995.
In 1996, VPN executed a Shareholder Agreement with United HealthCare Services,
Inc. (Purchaser), a wholly-owned subsidiary of UnitedHealth Group Incorporated,
by which VPN and Purchaser organized United HealthCare of Virginia, Inc. (UHC
Virginia), an HMO licensed to do business in Virginia as of October 1997.

   Until 1999, VPN served as the primary source of physician services for UHC
Virginia, as well as for other insurance products of UnitedHealth Group and its
subsidiary companies in Virginia. As described below, VPN owns approximately
49% of the outstanding shares of UHC Virginia. If the transactions described in
this proxy statement/prospectus are completed, UnitedHealth Group will acquire
these shares from VPN, and UHC Virginia will become an indirect wholly owned
subsidiary of UnitedHealth Group.

   UnitedHealth Group is a national leader in forming and operating markets for
the exchange of health and well-being services. In its five primary businesses,
UnitedHealth Group provides a broad spectrum of resources to help people

goals of Americans in the second half of life, age 50 and older; Uniprise,
which is devoted to serving the needs of large organizations; Specialized Care

leader in the field of health care data and information, research, analysis and
application. While separate, these businesses remain interrelated as part of
UnitedHealth Group's health and well-being enterprise. UnitedHealth Group's
businesses share customers, and in some instances, use common information
systems and have access to shared administrative services.

   As described below, UnitedHealth Group, through its UnitedHealthcare unit,
owns approximately 51% of the outstanding shares of UHC Virginia, a health
maintenance organization which provides healthcare services through
approximately 7,000 physicians located throughout the Commonwealth of Virginia.
If the transactions described in this proxy statement/prospectus are completed,
UnitedHealth Group will acquire the remaining outstanding shares of UHC
Virginia from VPN, and UHC Virginia will become an indirect wholly owned
subsidiary of UnitedHealth Group.

   UnitedHealth Group Incorporated, formerly known as United HealthCare
Corporation, is a Minnesota corporation, incorporated in January 1977. For
further information concerning UnitedHealth Group, please see "Certain
Information Concerning UnitedHealth Group" beginning on page 29 and refer to
the UnitedHealth Group documents which are incorporated by reference in this
proxy statement/prospectus as described under "Incorporation of Certain
Documents by Reference" at page 56.

   UnitedHealth Group effected a two-for-one split of its common stock on
December 22, 2000. The information presented throughout this proxy
statement/prospectus reflects this stock split.

Structure of the Transaction (see page 41)

   The proposed transaction, if approved by VPN shareholders, will be carried
out pursuant to an asset acquisition agreement dated December 29, 2000, among
UnitedHealth Group, Purchaser, and VPN, a copy of which is attached to this
proxy statement/prospectus as Annex A. Pursuant to the asset acquisition
agreement, Purchaser agrees to purchase 1,237.25 shares of UHC Virginia common
stock from VPN in exchange for a combination of (i) shares of UnitedHealth
Group common stock which will be paid to VPN, and (ii) Purchaser's resolution
of certain contested monetary obligations owing from VPN to Purchaser, as
follows:

  .  The number of shares of UnitedHealth Group common stock to be paid to
     VPN will be determined by dividing $17,948,278.04 by the "Parent Average
     Price." The "Parent Average Price" will be the average closing price per
     share of UnitedHealth Group common stock on the New York Stock Exchange
     for the 30 consecutive trading days ending with and including the third
     business day preceding the date the transactions called for by the asset
     acquisition agreement are completed. Based on the closing price of
     UnitedHealth Group common stock on the New York Stock Exchange on
     January 12, 2001 ($54.1875 per share), a total of 331,225 shares of
     UnitedHealth Group common stock would be paid to VPN.

     The shares of UnitedHealth Group common stock paid to VPN will be
     immediately distributed to VPN shareholders pro rata based on the number
     of shares of VPN common stock held by each shareholder. Based on the
     closing price of UnitedHealth Group common stock set forth above and the
     number of VPN shares outstanding on the date of this proxy
     statement/prospectus (assuming the cashless exercise of all currently
     exercisable options to purchase VPN shares), each shareholder of VPN
     would receive approximately 0.1493 shares of UnitedHealth Group common
     stock having a value of approximately $8.09 for each share of VPN common
     stock held by such shareholder. However, no fractional share of
     UnitedHealth Group common stock will be issued to any VPN shareholder.
     Instead, a cash payment will be made in lieu of such fractional share,
     as described under "The Asset Acquisition Agreement--Distribution of
     UnitedHealth Group Shares to VPN Shareholders."

  .  In addition, Purchaser will become responsible for the resolution of a
     contested liability represented by VPN's promissory note in the amount
     of $2,351,721.96 payable to Purchaser, and VPN will have no further
     liability on the note. VPN issued this note to Purchaser in November
     1999 pending final determination of the "cost-over-capitation" liability
     owing from VPN to Purchaser in connection with Purchaser's purchase of
     certain assets from VPN in June 1999. For a further description of this
     "cost- over-capitation" liability, see "The Proposed Transaction--
     Background of the Proposed Transaction."

                                       2

   The parties have agreed that the sale of UHC Virginia shares pursuant to the
asset acquisition agreement will satisfy VPN's right to "put" such shares to
Purchaser under an existing shareholders agreement between them. See "The
Proposed Transaction--Background of the Proposed Transaction."

   The asset acquisition agreement also provides that following this
transaction, VPN will dissolve and terminate its corporate existence in
accordance with its articles of incorporation, bylaws, and Virginia law as soon
as is practicable, and in any event not more than one year after this
transaction is completed.

Shareholder Approval (see page 17)

   In order for the proposed transaction to be completed, holders of more than
two-thirds of the shares of VPN common stock outstanding at the close of
business on January    , 2001 (the record date for the special meeting) must
approve the proposed transaction. UnitedHealth Group's shareholders are not
required to approve the proposed transaction.

   You are entitled to cast one vote per share of VPN common stock you owned as
of the record date for the special meeting.

Recommendation of VPN's Board of Directors (see page 22)

   After careful consideration, VPN's board of directors has unanimously
approved the asset acquisition agreement and the proposed transaction and has
determined that they are in the best interests of VPN's shareholders. VPN's
board of directors unanimously recommends that its shareholders vote FOR the
approval of the proposed transaction.

Conditions to the Proposed Transaction (see page 44)

   The parties' respective obligations to complete the proposed transaction are
subject to the prior satisfaction or waiver of certain conditions. The
following conditions, among others, must be satisfied or waived before the
completion of the proposed transaction:

  .  the proposed transaction must be approved by the holders of more than
     two-thirds of the shares of VPN common stock outstanding at the close of
     business on the record date for the special meeting;

  .  all necessary governmental and other third party consents must be
     obtained; and

  .  VPN must receive an opinion from its counsel to the effect that:

    .  the transfer of UHC Virginia shares by VPN pursuant to the asset
       acquisition agreement and the delivery of the shares of UnitedHealth
       Group common stock payable therefor to VPN's shareholders will be
       treated as a "reorganization" within the meaning of the Internal
       Revenue Code;

    .  VPN will recognize no gain or loss on the transfer of UHC Virginia
       shares by VPN pursuant to the asset acquisition agreement or on the
       delivery of the shares of UnitedHealth Group common stock payable
       therefore to VPN's shareholders; and

    .  VPN's shareholders will recognize no gain or loss on the transfer of
       UHC Virginia shares by VPN pursuant to the asset acquisition
       agreement or on the delivery of the shares of UnitedHealth Group
       common stock payable therefor to VPN's shareholders other than with
       respect to cash received in lieu of fractional shares or otherwise.

                                       3
<PAGE>


Termination of the Asset Acquisition Agreement (see page 45)

   The asset acquisition agreement may be terminated by mutual consent, or by
either UnitedHealth Group or VPN under certain circumstances, at any time
before the completion of the proposed transaction, including:

  .  if the proposed transaction is not completed, without the fault of the
     terminating party, on or before May 30, 2001;

  .  if VPN's shareholders do not approve the proposed transaction by the
     required vote;

  .  if the other party breaches any of its representations and warranties
     contained in the asset acquisition agreement or breaches or fails to
     perform in any material respect any of its agreements contained in the
     asset acquisition agreement and such breach or failure is not cured
     within 30 days after receipt of written notice from the non-breaching
     party.

   The asset acquisition agreement may also be terminated by UnitedHealth Group
if, among other things, VPN's board of directors withdraws or modifies in a
manner adverse to UnitedHealth Group or Purchaser its approval of the asset
acquisition agreement and the transaction contemplated thereby or its
recommendation that VPN's shareholders approve such transaction.

Interests of Certain Persons in the Proposed Transaction (see page 24)

   No person that is or has been at any time an executive officer or director
of VPN since the beginning of VPN's last fiscal year has any interest in the
proposed transaction that is different from or in addition to his interest as a
VPN shareholder generally, except that VPN will pay to C. Gregory Lockhart,
M.D. and K. Marshall Cook those sums contractually required to terminate their
existing employment agreements with VPN upon the dissolution and termination of
VPN.

U.S. Federal Income Tax Consequences of the Proposed Transaction (see page 25)

   We have structured the proposed transaction so that, in general, neither VPN
nor its shareholders will recognize gain or loss for United States federal
income tax purposes upon their receipt of shares of UnitedHealth Group common
stock pursuant to the asset acquisition agreement, except for taxes payable by
VPN shareholders because of cash received by them. It is a condition to the
completion of the proposed transaction that VPN receives a legal opinion from
its counsel to this effect.

   We urge you to carefully consider the discussion under "The Proposed
Transaction--Certain Federal Income Tax Considerations" and to consult your own
tax advisors regarding the specific tax consequences of the proposed
transaction to you.

Restrictions on the Ability to Sell UnitedHealth Group Common Stock (see page
28)

   All shares of UnitedHealth Group common stock you receive in connection with
the proposed transaction will be freely transferable unless you are considered
an "affiliate" of either VPN or UnitedHealth Group for purposes of Rule 145
promulgated under the Securities Act of 1933, in which case you will be
permitted to sell the shares of UnitedHealth Group common stock you receive
only in accordance with Rule 145.

No Dissenters' Rights

   Under the Virginia Stock Corporation Act, you are not entitled to
dissenters' rights in connection with the proposed transaction. Therefore, if
the proposed transaction is approved by the required two-thirds vote of VPN
shareholders, you will receive shares of UnitedHealth Group common stock
ratably with other VPN shareholders, regardless of whether or not you voted in
favor of the proposed transaction. You will not have the option of having the
"fair value" of your shares of VPN common stock determined by a court and paid
to you in cash by VPN.

                                       4
<PAGE>


Certain Effects of the Proposed Transaction (see page 47)

   Upon completion of the proposed transaction you will become a shareholder of
UnitedHealth Group, and upon the dissolution and termination of VPN called for
by the asset acquisition agreement you will cease to be a shareholder of VPN.
The internal affairs of UnitedHealth Group are governed by the Minnesota
Business Corporation Act and UnitedHealth Group's restated articles of
incorporation and bylaws. The proposed transaction and the dissolution and
termination of VPN will result in certain differences in the rights of VPN
shareholders. See "Comparison of Rights of Shareholders of UnitedHealth Group
and VPN."

(1) Excluding the operational realignment and other charges of $725, charges
    related to contract losses associated with certain Medicare markets and
    other increases to commercial and Medicare medical costs payable estimates
    of $175 and the convertible preferred stock redemption premium of $20 from
    the year ended December 31, 1998, 1998 earnings from operations, net
    earnings and net earnings applicable to common shareholders would have been
    $858, $537 and $509, respectively, or $1.31 diluted net earnings per common
    share.
(2) Excluding the merger costs associated with the April 1996 acquisition of
    HealthWise of America, Inc. ("HealthWise") of $15 ($9 after tax or $0.03
    diluted net earnings per common share) and the provision for future losses
    on two large multi-year contracts of $45 ($27 after tax, or $0.08 diluted
    net earnings per common share), 1996 earnings from operations and net
    earnings would have been $641 and $392, or $0.98 diluted net earnings per
    common share. The HealthWise merger was accounted for using the pooling-of-
    interests method of accounting; however, UnitedHealth Group did not restate
    its historical financial statements, as the effects on the historical
    consolidated financial statements were not material.
(3) Excluding restructuring charges associated with the October 1995
    acquisition of The MetraHealth Companies, Inc. ("MetraHealth") of $154 ($97
    after tax, or $0.28 diluted net earnings per common share), 1995 earnings
    from operations and net earnings would have been $615 and $383, or $1.06
    diluted net earnings per common share. The MetraHealth acquisition was
    accounted for using the purchase method of accounting and, accordingly, its
    operating results have been included in UnitedHealth Group's historical
    consolidated financial information from the acquisition date.

                     MARKET PRICE AND DIVIDEND INFORMATION

Recent Closing Prices

   There is no established public trading market for VPN common stock and, to
the knowledge of VPN, historical quotation information for such common stock in
the over-the-counter market is not available.

   The table below presents the closing price per share of UnitedHealth Group
common stock on the New York Stock Exchange, as adjusted to reflect
UnitedHealth Group's December 22, 2000 two for one stock split, on January 12,
2001, the last full trading day immediately preceding the filing of the
registration statement of which this proxy statement/prospectus is a part, and
on January  , 2001, the most recent practicable date prior to the mailing of
this document, as well as the "equivalent stock price" of shares of VPN common
stock on such dates. The "equivalent stock price" of shares of VPN common stock
represents the closing sales price per share for UnitedHealth Group's common
stock on the New York Stock Exchange on January 12, 2001 and January    , 2001,
multiplied by 0.1493 and 0.    . These decimals are estimates of the numbers of
shares of UnitedHealth Group common stock to be issued for each share of VPN
common stock under the asset acquisition agreement based on (i) the closing
price per share of UnitedHealth Group common stock on such dates, and (ii) the
number of VPN shares outstanding on the date of this proxy statement/prospectus
(assuming the cashless exercise of all currently exercisable options to
purchase VPN shares). Due to the operation of the formula set forth in the
asset acquisition agreement, the VPN "equivalent stock price" will not vary
with changes in the market price of UnitedHealth Group common stock. You should
recognize, however, that the market price of UnitedHealth Group common stock
may be lower on the day the proposed transaction is completed than its average
price during the 30-day calculation period for determining the number of shares
of UHG common stock to be issued, and that such market price will vary from day
to day after the proposed transaction is completed.

   As noted before, there is no established public trading market for VPN
common stock and, to the knowledge of VPN, historical quotation information for
such common stock in the over-the-counter market is not available.

Dividend Information

   UnitedHealth Group has paid a cash dividend equal to $.02 per share, per
year, on its common stock for its fiscal years 1999, 1998, 1997, 1996 and 1995.
VPN has never had sufficient earnings to pay a cash dividend to its
shareholders, and consequently no cash dividends have ever been declared or
paid on its common stock.

Number of Shareholders

   As of January 12, 2001, there were approximately 3,105 shareholders of
record who held shares of VPN common stock.

Shares Held by Certain VPN Shareholders

   As of January 12, 2001, the directors and executive officers of VPN and
their affiliates as a group held approximately 1.83% of the outstanding shares
of VPN and held presently exercisable options to acquire another approximately
7.55%. Approval of the transaction contemplated by the asset acquisition
agreement requires the affirmative vote of the holders of more than two-thirds
of the shares of VPN common stock outstanding at the close of business on the
record date for the special meeting.

                                  RISK FACTORS

   By voting in favor of the proposed transaction, you will be choosing to
invest in UnitedHealth Group common stock. In addition to the other information
contained in or incorporated by reference into this proxy statement/prospectus,
you should carefully consider the following risk factors in deciding whether to
approve and adopt the proposed transaction.

Risks Relating to the Proposed Transaction

   Subsequent Liabilities.

   The proposed transaction calls for the liquidation and dissolution of VPN as
soon as practicable, and in any event not more than one year after the
transactions provided for in the asset acquisition agreement are completed. VPN
shareholders generally will not be liable for VPN obligations to the extent
claims are asserted against VPN after such liquidation and dissolution for
liabilities incurred prior the liquidation and dissolution. However, under
certain circumstances, you, as a VPN shareholder, may be liable for certain
claims (for example, tax obligations) asserted against VPN after its
liquidation and dissolution, but only to the extent of the value of any
UnitedHealth Group stock and the amount of cash, if any, distributed to you in
connection with the proposed transaction. This risk is exacerbated by the
uncertainty surrounding the proper tax treatment of the settlement of the cost-
over-capitation liability. See "--Consideration Associated With Cost Over
Capitation Liability" and "The Proposed Transaction--Certain Federal Income Tax
Considerations--C Reorganization Requirements and Consequences--Boot and Debt
Resolution" and "--Other Consequences--Forgiveness of Debt" below.

   Minority Shareholder Status if Proposed Transaction is Not Completed.

   If the proposed transaction is not completed, VPN will continue to own 49%
of the outstanding shares of common stock of UHC Virginia. As such, VPN will
continue to be a minority shareholder of UHC Virginia, and will have limited
ability to control the policies and practices of UHC Virginia. In addition, it
will not have the ability to require the sale of UHC Virginia, or all or
substantially all of its assets. Further, VPN may be required to make
additional capital contributions to UHC Virginia. If the proposed transaction
is not completed and VPN remains a minority shareholder, the VPN Board of
Directors believes that it is unlikely that VPN shareholders will receive a
return that is equal to or greater than the price per share to be paid in the
proposed transaction.

   Consideration Associated With Cost-Over-Capitation Liability.

   As part of the consideration VPN will receive in the proposed transaction,
Purchaser will become responsible for the resolution of a contested liability
represented by VPN's promissory note in the amount of $2,351,721.96 payable to
Purchaser, and VPN will have no further liability on the note. VPN issued the
note to Purchaser in November 1999 pending final determination of the cost-
over-capitation liability owing from VPN to Purchaser in connection with
Purchaser's purchase of certain assets from VPN in June 1999. VPN and
UnitedHealth Group and Purchaser disagree as to VPN's cost-over-capitation
liability. The amount of consideration attributed to transfer of responsibility
for the note is different than the value placed on it by VPN. No assurances can
be given that the amount of consideration attributed to transfer of
responsibility for the note is equal to its fair value.

   Absence of Investment Banker's Opinion.

   No investment banker has been asked to give, nor has any given, its opinion
as the specific provisions or the fairness of the proposed transaction.
However, since early 1999, VPN has utilized the services of Cain Brothers &
Company, LLC, a nationally recognized investment banking firm that focuses
exclusively on the medical services industry, to act as a strategic and
financial adviser. Prior to the VPN shareholders' approval in 1999 of the
agreements that form the basis for the proposed transaction (including the
value of the consideration to be received by VPN or its shareholders), Cain
Brothers & Company, LLC rendered a written

                                       10
<PAGE>

opinion that the consideration to be received by VPN and its shareholders was
fair. Cain Brothers & Company, LLC continued its financial analysis of UHC
Virginia throughout 2000, meeting by telephone with the VPN Board of Directors
in October 2000 and concluding that it was unlikely that the value of VPN's
interest in UHC Virginia exceeded the guaranteed minimum available to VPN
shareholders under the existing agreements with Purchaser at that time.
Accordingly, you may take into account this information, but you are cautioned
to rely on your own determination as to the reasonableness of the terms of the
proposed transaction and the fairness of the consideration to be received by
VPN.

Risks Relating to UnitedHealth Group

   Health Care Costs.

   UnitedHealth Group uses a large portion of its revenue to pay the costs of
health care services or supplies delivered to its members. Total health care
costs that UnitedHealth Group incurs are affected by the number of individual
services rendered and the cost of each service. Much of UnitedHealth Group's
premium revenue is priced before services are delivered and the related costs
are incurred, usually on a prospective annual basis. Although UnitedHealth
Group bases the premiums it charges on its estimate of future health care costs
over the fixed premium period, competition, regulations and other 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, medical cost inflation, new mandated
benefits or other regulatory changes and insured population characteristics. In
addition, the earnings UnitedHealth Group reports for any particular quarter
include estimates of covered services incurred by its enrollees during that
period for claims that have not been received or processed. Because these are
estimates, UnitedHealth Group's earnings may be adjusted later to reflect the
actual costs. Relatively insignificant changes in the medical care ratio,
because of the narrow margins of UnitedHealth Group's health plan business, can
create significant changes in UnitedHealth Group's earnings.

   In addition, UnitedHealth Group's 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 that this pattern will continue, 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 and has
been the subject of large jury awards. This publicity has been accompanied by
increased litigation, legislative activity, regulation and governmental review
of industry practices. These factors may adversely affect UnitedHealth Group's
ability to market its products or services, may require it to change its
products and services, and may increase the regulatory burdens under which it
operates, further increasing its costs of doing business and adversely
affecting its profitability.

   Competition.

   In many of UnitedHealth Group's geographic or product markets, UnitedHealth
Group competes with a number of other entities, some of which may have certain
characteristics or capabilities that give them a competitive advantage.
UnitedHealth Group believes 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 providers of
health and well-being services. Certain of UnitedHealth Group's customers may
decide to perform for themselves functions or services that UnitedHealth Group
provides, which would decrease UnitedHealth Group's revenues. Certain of
UnitedHealth Group's contracted providers may decide to market products and
services to UnitedHealth Group's customers in competition with UnitedHealth
Group. In addition, significant merger and acquisition activity has occurred in
the industry in which UnitedHealth Group operates as well as in industries that
act as suppliers to UnitedHealth Group, such as the hospital, physician,
pharmaceutical, medical device and health information systems industries. To
the extent that there is strong

                                       11
<PAGE>

competition or that competition intensifies in any market, UnitedHealth Group's
ability to retain or increase customers or providers, or maintain or increase
its revenue growth, pricing flexibility, control over medical cost trends and
marketing expenses may be adversely affected.

   AARP Contract.

   Under UnitedHealth Group's long-term contract with AARP, UnitedHealth Group
provides Medicare supplemental, hospital indemnity health insurance and other
products to AARP members. As a result of the agreement, the number of members
UnitedHealth Group serves, products UnitedHealth Group offers, and services
UnitedHealth Group provides has grown significantly. As of September 30, 2000,
UnitedHealth Group's portion of AARP's insurance program represents
approximately $3.5 billion in annual net premium revenue from approximately 3.6
million AARP members. The success of the AARP arrangement will depend, in part,
on UnitedHealth Group's 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 AARP or one of its other business
partners for its member insurance program could have an adverse effect on the
success of UnitedHealth Group's arrangement with AARP.

   Medicare Operations.

   In the second quarter of 1998, UnitedHealth Group experienced a significant
rise in the medical care ratio for UnitedHealth Group's 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, UnitedHealth Group announced in October 1998
its decision to withdraw Medicare product offerings from 86 of the 206 counties
it then served. The decision, effective January 1, 1999, affected approximately
60,000, or 12%, of Medicare members as of December 31, 1998. On July 1, 1999,
UnitedHealth Group announced its decision to withdraw Medicare+Choice product
offerings from an additional 49 counties. This decision, effective January 1,
2000, affected approximately 40,000 additional Medicare members. Also effective
January 1, 2000, UnitedHealth Group filed significant benefit adjustments. In
June 2000, UnitedHealthcare announced that it will not renew its
Medicare+Choice contracts in 21 counties across the United States, effective
January 1, 2001, affecting 56,000 individuals served. Annual revenues for 2000
from the Medicare markets UnitedHealth Group is exiting effective January 1,
2001, are expected to be approximately $320 million. These actions and other
actions are expected to further reduce Medicare enrollment and may result in
further withdrawals of Medicare product offerings, when and as permitted by
UnitedHealth Group's contracts with the Health Care Financing Administration
("HCFA"). As a consequence of these withdrawals, UnitedHealth Group is
precluded from re-entering these counties with Medicare product offerings until
5 years after the respective effective date of withdrawal.

   UnitedHealth Group will continue to offer Medicare products in strong and
economically viable markets. However, its ability to improve the financial
results of all of its Medicare operations will depend on a number of factors,
including future premium increases, growth in markets where it has achieved
sufficient size to operate efficiently, benefit design, provider contracting
and other factors. There can be no assurance that UnitedHealth Group will be
able to successfully prevent future losses on its Medicare operations.

   Realignment of Operations.

   In the second quarter of 1998, UnitedHealth Group recognized a charge to
earnings for its realignment. The original operational realignment plan
provided for substantial completion in 1999. UnitedHealth Group continues to
implement its original realignment plan. However, some initiatives including
the consolidation of certain claims and administrative processing functions and
certain divestitures and market realignment activities have required additional
time to complete in the most effective manner and to obtain certain required
regulatory approvals, and will extend through the middle of 2001. Based on
current facts and circumstances, UnitedHealth Group believes the remaining
realignment reserve is adequate to cover the costs to be incurred in executing
the remainder of the plan. However, as UnitedHealth Group proceeds with the
execution of the plan and more

                                       12
<PAGE>

current information becomes available, it may be necessary for UnitedHealth
Group to adjust its estimates for severance, lease obligations on exited
facilities and losses on disposition of businesses.

   Government Programs and Regulation.

   UnitedHealth Group's business is heavily regulated at federal, state and
local levels. The laws and rules governing UnitedHealth Group's 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 UnitedHealth Group to change how it does
business, restrict revenue and enrollment growth, increase its health care and
administrative costs and capital requirements, and increase its liability for
medical malpractice or other actions. UnitedHealth Group must obtain and
maintain regulatory approvals to market many of its products. Delays in
obtaining or failure to obtain or maintain these approvals could adversely
affect its revenue or could increase its costs. UnitedHealth Group participates
in federal, state and local government health care coverage programs. These
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 reduce or increase UnitedHealth Group's
administrative or health care costs under such programs. Such changes have
adversely affected UnitedHealth Group's results and willingness to participate
in such programs in the past and may also do so in the future.

   State legislatures and Congress continue to focus on health care issues. In
Congress, managed health care has been the subject of proposed legislation, in
the form of a "Patients Bill of Rights" bill. In addition, other proposed bills
and regulations may impact certain aspects of UnitedHealth Group's business
including provider contracting, claims payments and processing, confidentiality
of health information and government-funded programs. Further, tax code changes
considered from time to time by Congress may make it easier and more cost
effective for employers to establish deferred contribution plans. While
UnitedHealth Group cannot predict if any of these initiatives will ultimately
become binding law or regulation, or if enacted, what their terms will be,
their enactment could increase UnitedHealth Group's costs, expose it to
expanded liability, require it to revise the ways in which it conducts business
or put it at risk for a loss of business to new health care funding
arrangements. As UnitedHealth Group's businesses continue to implement their e-
commerce initiatives, uncertainty surrounding the regulatory authority and
requirements in this area will make it difficult to ensure compliance.

   UnitedHealth Group is also 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 civil or
criminal fines, penalties and other sanctions. In addition, disclosure of any
adverse investigation or audit results or sanctions could damage UnitedHealth
Group's reputation in various markets and make it more difficult for it to sell
its products and services. UnitedHealth Group is currently involved in various
governmental investigations, audits and reviews. These include routine, regular
and special audits by HCFA, state insurance departments, the Office of
Personnel Management and the Office of the Inspector General. UnitedHealth
Group does not believe the results of any of the current audits, individually
or in the aggregate, will have a material adverse effect on its financial
position or results.

   UnitedHealth Group's operations are conducted through its wholly owned
subsidiaries, which include 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 may 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 September 30, 2000, UnitedHealth Group'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 approximately $400 million.

   Provider Relations.

   One of the significant techniques UnitedHealth Group uses to manage health
care costs and facilitate care delivery is contracting with physicians,
hospitals and other providers. Because UnitedHealth Group's health

                                       13
<PAGE>

plans are geographically diverse and most of those health plans contract with a
large number of providers, UnitedHealth Group currently believes its aggregate
exposure to provider relations issues is limited. A number of organizations are
advocating for legislation that would exempt certain providers from federal and
state antitrust laws, the adoption of which could impact this assessment. In
any particular market, providers could refuse to contract, demand higher
payments, or take other actions that could result in higher health care costs,
less desirable products for customers 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. In
addition, physician or practice management companies, which aggregate physician
practices for administrative efficiency and marketing leverage, continue to
expand. These providers may compete directly with UnitedHealth Group. If these
providers refuse to contract with UnitedHealth Group, use their market position
to negotiate favorable contracts, or place UnitedHealth Group at a competitive
disadvantage, those activities could adversely affect UnitedHealth Group's
ability to market products or to be profitable in those areas.

   Litigation and Insurance.

   UnitedHealth Group 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 UnitedHealth Group's business,
UnitedHealth Group is subject to a variety of legal actions relating to its
business operations, including the design, management and offering of its
products and services. These could include: claims relating to the denial of
health care benefits; medical malpractice actions; allegations of anti-
competition and unfair business activities; 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 calculations; claims related to the
failure to disclose certain business practices; and claims relating to customer
audits and contract performance. A number of class action lawsuits have been
filed against UnitedHealth Group and certain of its competitors in the managed
care business. The suits are purported class actions on behalf of all of
UnitedHealth Group's managed care members and network providers for alleged
breaches of federal statutes, including the Employee Retirement Income Security
Act and the Racketeer Influenced Corrupt Organization Act. While UnitedHealth
Group believes these suits against it are without merit and intends to defend
its position vigorously, it will incur expenses in the defense of these matters
and cannot predict their outcome.

   Recent court decisions and legislative activity may increase UnitedHealth
Group's exposure for any of these types of claims. In some cases, substantial
non-economic, treble or punitive damages may be sought. UnitedHealth Group
currently has 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.

   UnitedHealth Group's businesses depend significantly on effective
information systems, and UnitedHealth Group has many different information
systems for its various businesses. Its information systems require an ongoing
commitment of significant 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 and regulatory standards,
and changing customer preferences. For example, the Health Insurance
Portability and Accountability Act's ("HIPAA's") administrative simplification
provisions and the Department of Labor's claim processing regulations may
ultimately require significant changes to current systems. In addition,
UnitedHealth Group may from time to time obtain significant portions of its
systems-related or other services or facilities from independent third parties,
which may make its operations vulnerable to such third parties'

                                       14
<PAGE>

failure to perform adequately. As a result of UnitedHealth Group's acquisition
activities, it has acquired additional systems and has been taking steps to
reduce the number of systems and has upgraded and expanded its information
systems capabilities. Failure to maintain effective and efficient information
systems could cause the loss of existing customers, difficulty in attracting
new customers, issues in determining medical cost estimates, customer and
provider disputes, regulatory problems, increases in administrative expenses or
other adverse consequences.

   Administrative and Management.

   Efficient and cost-effective administration of UnitedHealth Group's
operations is essential to its profitability and competitive positioning. While
UnitedHealth Group attempts to effectively manage expenses, staff-related and
other administrative expenses may arise 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. Further, UnitedHealth
Group believes it currently has 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 key employees or a number of managers or technical
staff could adversely affect UnitedHealth Group's ability to administer and
manage its business.

   Marketing.

   UnitedHealth Group markets its products and services through both employed
sales people and independent sales agents. Although UnitedHealth Group has many
sales employees and agents, the departure of certain key sales employees or
agents or a large subset of these individuals could impair its ability to
retain existing customers and members. In addition, certain of its customers or
potential customers consider rating, accreditation or certification of
UnitedHealth Group by various private or governmental bodies or rating agencies
necessary or important. Certain of its 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 its ability to obtain or retain business with these customers.

   Acquisitions and Dispositions.

   UnitedHealth Group 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 transactions 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 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 UnitedHealth Group's knowledge and
information-related business depend significantly on the integrity of the data
on which they are based. If the information contained in UnitedHealth Group's
databases were found or perceived to be inaccurate, or if such information were
generally perceived to be unreliable, commercial acceptance of UnitedHealth
Group's database-related products would be adversely and materially affected.
Furthermore, the use of individually identifiable data by UnitedHealth Group's
businesses 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 certain of UnitedHealth
Group's products or services and, more generally, affect UnitedHealth Group's
business, financial condition and results of operations.

   There are various proposals currently under consideration that address the
use of individually identifiable health data from federal and state legislative
and regulatory bodies. The United States Department of Health and Human
Services has recently released final regulations regarding this issue, as
directed under HIPAA.

                                       15
<PAGE>

UnitedHealth Group is currently evaluating the effect these rules will have on
its existing policies and practices and anticipates that certain systems
changes and new administrative processes will be required, which may lead to
cost increases. Additionally, if state and/or federal laws are enacted, some of
these provisions may impose restrictions on UnitedHealth Group's use of patient
data and may increase UnitedHealth Group's cost to use health care data.

   The success of UnitedHealth Group's knowledge and information-related
business also depends significantly on its ability to maintain proprietary
rights to its products. UnitedHealth Group relies on its agreements with
customers, confidentiality agreements with employees, and its trade secrets,
copyrights and patents to protect its proprietary rights. UnitedHealth Group
cannot assure that these legal protections and precautions will prevent
misappropriation of its proprietary information. In addition, substantial
litigation regarding intellectual property rights exists in the software
industry, and UnitedHealth Group expects 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 effect on the ability of UnitedHealth Group's knowledge and
information-related business to market and sell its products and on its
business, financial condition and results of operations.

   Financial Outlook.

   From time to time in earnings releases and otherwise, UnitedHealth Group may
publish forecasts or other forward-looking statements regarding its future
results, including estimated revenues or net earnings. Any forecast of its
future performance reflects various assumptions. These assumptions are subject
to significant uncertainties, and as a matter of course, any number of them may
prove to be incorrect. Further, the achievement of any forecast depends on
numerous risk and other factors (including those described in this discussion),
many of which are beyond UnitedHealth Group's control. As a result,
UnitedHealth Group cannot assure you that its performance will be consistent
with any management forecasts or that the variation from such forecasts will
not be material and adverse. You are cautioned not to base your entire analysis
of UnitedHealth Group's business and prospects upon isolated predictions, but
instead are encouraged to utilize UnitedHealth Group's entire publicly
available mix of historical and forward-looking information, as well as other
available information affecting UnitedHealth Group and its services, when
evaluating UnitedHealth Group's prospective results of operations.

   Stock Market.

   The market prices of the securities of the publicly-held companies in the
industry in which UnitedHealth Group operates have shown volatility and
sensitivity in response to many factors, including general market trends,
public communications regarding managed care, litigation and judicial
decisions, legislative or regulatory actions, health care cost trends, pricing
trends, competition, earnings, membership reports of particular industry
participants and acquisition activity. UnitedHealth Group cannot assure the
level or stability of the price of its securities at any time or the impact of
the foregoing or any other factors on such prices.

                    THE SPECIAL MEETING OF VPN SHAREHOLDERS

   This proxy statement/prospectus is furnished in connection with the
solicitation of proxies from the holders of VPN common stock by VPN board of
directors for use at the Special Meeting of VPN shareholders.

Date, Time and Place of the Special Meeting

   The Special Meeting will be held at      a.m., local time, on          ,
              , 2001, at                 .

Matters to be Considered at the Special Meeting

   At the Special Meeting, VPN shareholders will be asked to consider and vote
upon a proposal to approve (a) the sale of substantially all of VPN's assets,
consisting of approximately 49% of the outstanding shares of UHC Virginia, to
Purchaser in exchange for shares of UnitedHealth Group common stock which will
be distributed to VPN shareholders and for the resolution of certain contested
monetary obligations of VPN, all pursuant to the asset acquisition agreement,
and (b) the subsequent dissolution and termination of VPN as required by the
asset acquisition agreement.

Record Date and Shares Entitled to Vote

   VPN's board of directors has fixed the close of business on January  , 2001,
as the record date for determination of VPN shareholders entitled to notice of
and to vote at the Special Meeting. As of the close of business on the record
date, there were              shares of VPN common stock outstanding and
entitled to vote, held of record by approximately    shareholders. A majority
of these shares, present in person or represented by proxy, will constitute a
quorum for the transaction of business. If a quorum is not present, it is
expected that the Special Meeting will be adjourned or postponed to solicit
additional proxies. Each VPN shareholder is entitled to one vote for each share
of VPN common stock held as of the record date.

Voting of Proxies; Revocation of Proxies

   You are requested to complete, date and sign the enclosed proxy and return
it to VPN immediately by faxing it to (804) 771-5625 or by mailing it in the
enclosed pre-addressed, postage-paid envelope. All properly executed proxies
received by VPN prior to the vote at the Special Meeting, and that are not
revoked, will be voted in accordance with the instructions indicated on the
proxies or, if no direction is indicated, to approve the proposed transaction.
Votes will be tabulated by the inspectors of election appointed by VPN.

   VPN's board of directors does not presently intend to bring any other
business before the Special Meeting and, so far as is presently known to VPN's
board of directors, no other matters are to be brought before the Special
Meeting. As to any business that may properly come before the Special Meeting,
however, it is intended that proxies, in the form enclosed, will be voted in
respect thereof in accordance with the judgment of the persons voting such
proxies.

   You may revoke your proxy at any time prior to its use by delivering to the
Secretary of VPN a signed notice of revocation or a later-dated, signed proxy,
or by attending the special meeting and voting in person. Attendance at the
Special Meeting does not in itself constitute the revocation of a proxy.

Vote Required

   Approval of the sale of substantially all of VPN's assets pursuant to the
asset acquisition agreement and the subsequent dissolution and termination of
VPN as required by the asset acquisition agreement is required by the Virginia
Stock Corporation Act. Such approval requires the affirmative vote of the
holders of more than two-thirds of the shares of VPN common stock outstanding
and entitled to vote at the special meeting.

Quorum; Abstentions and Broker Non-Votes

   The required quorum for the transaction of business at the Special Meeting
is a majority of the shares of VPN common stock issued and outstanding on the
record date. Abstentions will be included in determining the number of shares
present and voting at the meeting for the purpose of determining the presence
of a quorum. Because approval of the proposed transaction requires the
affirmative vote of more than two-thirds of the outstanding shares of VPN
common stock entitled to vote, abstentions will have the same effect as votes
against the proposed transactions. In addition, the failure of a VPN
shareholder to return a proxy will have the effect of a vote against the
approval of the proposed transaction.

Expenses of Solicitation

   VPN will pay its out-of-pocket expenses of soliciting proxies from you. In
addition to solicitation by mail, the directors and officers of VPN may solicit
proxies from shareholders by telephone, facsimile or in person.

Board Recommendation

   THE VPN BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT VPN SHAREHOLDERS VOTE
FOR THE APPROVAL OF THE PROPOSED TRANSACTION.

                            THE PROPOSED TRANSACTION

   This section of the proxy statement/prospectus describes material aspects of
the proposed transaction. While we believe that the description covers the
material terms of the asset acquisition agreement and the transactions provided
for therein, this summary may not contain all of the information that is
important to you. You should read this entire document, the attached annex and
the other documents we refer to carefully for a more complete understanding of
the proposed transaction.

Background of the Proposed Transaction

 General.

   VPN was organized as a 100% physician-owned, statewide network of physicians
and incorporated in Virginia on August 9, 1995. Pursuant to the initial
Shareholder Agreement (Shareholder Agreement I) between VPN and Purchaser, VPN
and Purchaser organized UHC Virginia, an HMO licensed to do business in
Virginia as of October 1997. Purchaser owns 51% and VPN owns 49% of UHC
Virginia. Under Shareholder Agreement I, VPN was granted authority to elect
five of eleven directors to the UHC Virginia Board of Directors, one of whom
was the chairman of the board. A majority of both Purchaser and VPN
representatives to the UHC Virginia Board of Directors had to approve the
annual budget, any amendment or repeal of its articles of incorporation or
bylaws, the determination of a need for and raising of additional capital and
twelve other items specifically detailed in Shareholder Agreement I. In
addition, Shareholder Agreement I assured VPN a majority of the members on UHC
Virginia committees that dealt with patient care (credentialing, quality
assurance, utilization management, medical policy and guidelines).

   In the event that the UHC Virginia Board of Directors determined that
additional capital was necessary, Shareholder Agreement I required Purchaser to
provide 51% and VPN to provide 49% of that capital. If either party was unable
or refused to provide its portion of necessary capital within 75 days of the
UHC Virginia Board's determination, the other party could do so and obtain the
appropriate number of additional shares in UHC Virginia.

   VPN served as the primary source of physician services for UHC Virginia, as
well as for other insurance products of UnitedHealth Group and its subsidiary
companies in Virginia pursuant to a Provider Agreement dated March 1, 1996,
between VPN and UHC Virginia. Until July 1, 1999, VPN provided these physician
services to UHC Virginia under a global capitation arrangement. Physicians were
reimbursed on a discounted fee-for-service basis. VPN also received a network
access fee from United HealthCare Insurance Company (UHI), a subsidiary of
UnitedHealth Group, for access to VPN's network of physicians under the terms
of a letter agreement with UHI, dated April 27, 1998.

   Sales of UHC Virginia's HMO product began in October 1997 and grew
significantly. On December 31, 1997, UHC Virginia had approximately 5,000
members. By December 1998, that number had grown to more than 46,000, and by
June 1999 to more than 67,000. Since then this number has remained relatively
stable.

 VPN and UHC Virginia Financial Losses.

   Both VPN and UHC Virginia faced financial challenges as a result of this
rapid growth in membership. Prior to July 1, 1999, VPN received revenue from
two sources (other than its investment income): (i) its capitation payment from
UHC Virginia and (ii) the network access fee paid by UHI. When UHC Virginia
began operations in 1997, its Board of Directors voted to withhold a 10%
financial allowance under each physician's individual provider agreement to
cushion the network against potential financial losses under the capitation
payment agreement with UHC Virginia. Even with this 10% cushion, however, VPN
spent at least $1.26 million more in physician reimbursements than it received
in 1998. Capitation losses for VPN for 1999 were even more significant.

   Financial losses for UHC Virginia, in which VPN owned a 49% interest, were
equally significant. Audited financial statements for UHC Virginia showed a net
operating loss of $734,069 in 1997 and of $5,665,339 in 1998. The book value of
VPN's interest in UHC Virginia dropped from $4,326,300 on December 31, 1997 to
$1,550,068 on December 31, 1998.

 Capital Infusions Required in 1999.

   In March 1999, UHC Virginia required a capital infusion of $1.25 million to
maintain the minimum net worth required by Virginia law. VPN contributed its
49% portion ($612,500) of that capital infusion on March 30, 1999, and
Purchaser contributed its 51% portion ($637,500) as well.

   On June 8, 1999, UHC Virginia received correspondence from the Virginia
Bureau of Insurance that significantly more capital would be required by the
Bureau for UHC Virginia to maintain its statutorily-required net worth. At its
meeting on June 29, 1999, the UHC Virginia Board of Directors reviewed and
discussed the correspondence from the Virginia Bureau of Insurance and the net
worth requirements and unanimously determined that UHC Virginia required
additional capital of $14 million by June 30, 1999 to continue to do business
in Virginia. Purchaser funded its 51% of the additional capital infusion with
cash and loaned VPN $6.86 million (VPN's 49% of the required capital). VPN
signed a $6.86 million Promissory Note and used the loan proceeds for its 49%
portion of the required capital call. As a result of this loan, VPN maintained
its 49% ownership interest in UHC Virginia. Without this loan, VPN would not
have had sufficient assets to satisfy its 49% portion of the capital call.

 UnitedHealth Group Negotiations.

   Facing losses through its capitation agreement with UHC Virginia and a
reduction in the book value of its 49% ownership in UHC Virginia, the VPN Board
of Directors on January 24, 1999 authorized the officers of VPN to begin
negotiations with UnitedHealth Group to attempt to resolve the financial
problems faced by VPN and UHC Virginia. These negotiations began immediately,
and VPN retained the services of Cain Brothers, Inc. a New York investment
banking firm that focuses exclusively on the medical services industry, to
assist in these negotiations and in the necessary financial analyses to support
VPN's position.

   Negotiations ended in late June 1999, with the unanimous approval by the VPN
Board of Directors of an Asset Purchase Agreement, a Second Amendment and
Restatement of Shareholder Agreement, and other related agreements between VPN
and Purchaser (the "Agreements"), and a Plan of Complete Liquidation and
Dissolution (the "Liquidation Plan"). The Agreements and the Liquidation Plan
were approved by the affirmative vote of more than two-thirds of the votes
entitled to be cast at an October 6, 1999 meeting of the VPN shareholders.

 The Agreements.

   The Asset Purchase Agreement. Purchaser and VPN entered into an Asset
Purchase Agreement dated June 30, 1999, pursuant to which Purchaser purchased
certain assets from VPN for $8 million. The Asset Purchase Agreement was
designed to provide VPN the funds (i) to satisfy its $6.86 million loan, the
proceeds of which were used to satisfy its 49% portion of the $14 million
capital infusion described above, in addition to interest accrued on the loan,
and (ii) to augment VPN's operating funds until a Liquidity Event (as was
defined in the Second Amendment and Restatement of Shareholder Agreement)
occurred. Among the primary assets of VPN were (i) its individual Physician
Participation Agreements with its physicians ("Physician Contracts"), (ii) its
network access fee from UHI, and (iii) its 49% ownership interest in UHC
Virginia. Under the terms of the Asset Purchase Agreement, VPN sold,
transferred and assigned to Purchaser all of its Physician Contracts and all
records relating to VPN's participating physicians, its right to receive the
network access fee from UHI, and all information relating to health services
provided or arranged by VPN. VPN retained its 49% ownership interest in UHC
Virginia.

   In the Asset Purchase Agreement, VPN agreed to satisfy all claims for
physician reimbursement under its global capitation agreement with UHC Virginia
for the period ending December 31, 1998. VPN paid $1.26 million from its
operating funds to UHC Virginia to satisfy this requirement on July 15, 1999.
VPN further agreed to satisfy all claims for physician reimbursement under its
global capitation agreement with UHC Virginia for the period from January 1,
1999 through June 30, 1999. This liability ("cost-over-capitation" liability)
was estimated at approximately $3.2 million.


                                       20
<PAGE>

   VPN intended to satisfy the cost-over-capitation liability through a loan it
would obtain either from a third-party lender or from the Purchaser. Purchaser
agreed to loan VPN the funds to satisfy the cost-over-capitation liability at
an interest rate of prime plus 1% and collateralized by all shares of UHC
Virginia held by VPN that were unencumbered on the date the loan was executed.
The maturity date of the loan from Purchaser would be the closing date
associated with a Liquidity Event. Beginning July 1, 1999, UHC Virginia agreed
to assume full responsibility for claims for physician reimbursement.

   The Second Amendment and Restatement of Shareholder Agreement. As part of
their financial arrangements, VPN and Purchaser entered into a Second Amendment
and Restatement of Shareholder Agreement, dated June 30, 1999 ("Shareholder
Agreement II"). Shareholder Agreement II was an amended and restated version of
Shareholder Agreement I, which also was amended effective January 1, 1998 to
facilitate HMO operations in states adjoining Virginia. Shareholder Agreement
II was intended to permit VPN to retain its 49% ownership in UHC Virginia and
its positions on the UHC Virginia Board of Directors and committees while
providing UHC Virginia with additional time to achieve profitability. It also
created (i) a purchase option in favor of Purchaser and a subsequent
requirement for VPN to sell its interest in UHC Virginia (a call right), and
(ii) a sale option in favor of VPN and a subsequent requirement for Purchaser
to purchase VPN's interest (a put right) at fair market value by a certain
date, whether or not UHC Virginia had become profitable, with minimum and
maximum values established for VPN's 49% interest in UHC Virginia.

   The amendments to Shareholder Agreement I contained in Shareholder Agreement
II included provisions that established a Valuation Methodology for stock in
UHC Virginia for purposes of the put and call rights in Shareholder Agreement
II. The Valuation Methodology agreed upon would value UHC Virginia stock at
fair market value, subject to a $20 million minimum valuation for all of VPN's
shares in UHC Virginia and a $40 million maximum valuation for such shares. The
put and call rights, as well as the Valuation Methodology, applied (with
exceptions described below) in the following circumstances ("Liquidity
Events"):

  .  On April 1, 2003, VPN at its sole discretion could require that
     Purchaser purchase all of VPN's stock in UHC Virginia. The purchase,
     again at VPN's sole option, could be made either by exchanging certain
     shares of common voting stock of UnitedHealth Group or cash. In this
     instance, the valuation of UHC Virginia stock would be based on a 2002
     fiscal year end valuation. VPN's fiscal year ends on December 31.

  .  On April 1, 2004, if VPN had not exercised its rights described in the
     first bullet point above, then VPN would be required to sell, and
     Purchaser would be required to purchase, all of VPN's shares in UHC
     Virginia. The purchase, at VPN's sole option, could be made either by
     exchanging certain shares of common voting stock of UnitedHealth Group
     or cash. In this instance, the valuation of UHC Virginia stock would be
     based on a 2003 fiscal year end valuation.

  .  If UHC Virginia requested the infusion of any further capital, VPN had
     the option to require Purchaser to purchase all of its shares in UHC
     Virginia for a total price of $20 million. Any capital call required a
     majority vote of both Purchaser and VPN representatives on the UHC
     Virginia Board of Directors, except that no such supermajority consent
     was required if the capital infusion was necessary to satisfy UHC
     Virginia's regulatory requirements. VPN could elect to receive the total
     price either in shares of UnitedHealth Group or cash. This right had to
     be exercised by VPN within 30 days of the date VPN first learned of the
     additional capital call.

  .  Purchaser had the right to purchase all of VPN's shares in UHC Virginia
     on any date prior to January 1, 2001, for a total price of $30 million.
     VPN could elect to receive this total price either in shares of
     UnitedHealth Group or in cash.

  .  VPN had the right to require Purchaser to purchase all of VPN's shares
     in UHC Virginia on any date if Purchaser materially breached Shareholder
     Agreement II. The sale, at VPN's sole option, could be made either by
     exchanging certain shares of common voting stock of UnitedHealth Group
     or cash. In this instance, the valuation of UHC Virginia would be fair
     market value at the time of the material breach.

                                       21
<PAGE>

   The Agreements were overwhelmingly approved by VPN shareholders at a meeting
held on October 6, 1999. At the closing on the Agreements that occurred on
November 5, 1999, VPN executed a Note to Purchaser for $2,351,731.96,
representing its estimated cost-over-capitation liability less a portion of
that debt VPN paid from its operating funds. VPN's shares in UHC Virginia were
pledged as security for that loan. A First Amendment to the Asset Purchase
Agreement was signed, establishing an independent audit procedure to calculate
an actual amount for VPN's cost-over-capitation liability.

 Additional Capital Required.

   In late 1999, UHC Virginia was notified by the Virginia Bureau of Insurance
that additional capital would be required for the HMO to maintain the minimum
net worth required by statute. A letter agreement was signed by VPN and the
Purchaser, pursuant to which the Purchaser agreed to (i) loan UHC Virginia
sufficient funds to satisfy state requirements, and (ii) extend VPN's put right
for its shares in UHC Virginia as described in the third bullet point above
until December 31, 2000.

 VPN Board of Directors Meetings.

   The VPN Board of Directors met seven times in 2000, largely (i) to review
UHC Virginia's financial reports, budget and operations and (ii) to receive
reports from its independent auditor on its cost-over-capitation liability to
Purchaser and from Cain Brothers & Company, LLC on its financial analysis of
UHC Virginia's operations.

   Following its October meeting, the directors instructed VPN's management to
begin discussions with Purchaser to effect its put of VPN's shares of UHC
Virginia to Purchaser. The proposed transaction is the result of those
negotiations and was approved unanimously at the December 28, 2000 meeting of
the VPN Board of Directors.

VPN's Reasons for the Proposed Transaction and Board of Directors
Recommendation

   In reaching its conclusion to approve the asset acquisition agreement and
the transaction provided for therein, the board of directors of VPN considered
a number of factors, including, without limitation, the following:

  .  Financial losses for UHC Virginia in 1999 and in 2000 were significant.
     At regular and special meetings held throughout both years, VPN's board
     of directors received reports from management of UHC Virginia that
     significant capital infusions were required due to these operating
     losses. Pursuant to the agreements with Purchaser approved by VPN
     shareholders in October 1999, VPN satisfied its obligations for its
     portion of capital by assigning virtually all its assets to Purchaser,
     except its 49% ownership interest in UHC Virginia.

  .  The resolution of the contested cost-over-capitation liability of VPN to
     Purchaser, estimated in the earlier agreements with Purchaser to be
     approximately $3.2 million, was proving to be time consuming and could
     have become more costly to VPN. The resolution of this contested VPN
     liability through the proposed transaction, compared to the alternative
     methods in the existing agreements with Purchaser to contest and
     determine what, if any, cost-over-capitation liability VPN had to
     Purchaser, was preferable.

  .  Since early 1999, VPN has utilized the services of Cain Brothers &
     Company, LLC, a nationally recognized investment banking firm that
     focuses exclusively on the medical services industry, to act as a
     strategic and financial advisor. Prior to the VPN shareholders' approval
     in 1999 of the agreements that form the basis for the proposed
     transaction (including the value of the consideration to be received by
     VPN and its shareholders), Cain Brothers & Company, LLC rendered a
     written opinion to the VPN Board of Directors that the consideration to
     be received by VPN and its shareholders was fair to such shareholders.
     Cain Brothers & Company, LLC continued its financial analysis of UHC
     Virginia throughout 2000, meeting with the VPN Board of Directors in
     October

                                       22
<PAGE>

     2000 by telephone and concluding that it was unlikely that the value of
     VPN's interest in UHC Virginia exceeded the guaranteed minimum available
     to VPN shareholders under the existing agreements with Purchaser at that
     time.

     VPN contracted to pay Cain Brothers & Company, LLC a fee for its
     strategic and financial advisory services in connection with the
     negotiation of the earlier agreements with Purchaser and contingent on
     the closing of those agreements. This fee equals 1% of the first $15
     million purchase price for VPN's interest in UHC Virginia and 4% of that
     portion of the purchase price in excess of $15 million. An additional
     fee of $100,000 was paid to Cain Brothers & Company, LLC for preparation
     of the fairness opinion in 1999, concerning the earlier agreements with
     Purchaser.

  .  There would be beneficial tax consequences for VPN and VPN shareholders
     if the transaction was treated as a reorganization within the meaning of
     Section 368(a)(1)(C) of the Internal Revenue Code of 1986, as amended,
     as provided in the asset acquisition agreement.

  .  VPN's put under existing agreements with Purchaser was required to be
     exercised on or before December 31, 2000, and could not be exercised
     thereafter until April 1, 2003.

   The discussion above addresses the material factors considered by the VPN
board of directors in its consideration of the proposed transaction. In view of
the variety of factors and the amount of information considered, the VPN board
did not find it practical to, and did not, make specific assessments of,
quantify or otherwise assign relative weights to the specific factors
considered in making its determination. The determination was made after
consideration of all of the factors as a whole. In addition, individual members
of the VPN board may have given different weights to the different factors. For
a discussion of the interests of certain members of VPN's management and the
VPN board of directors in the proposed transaction, see "--Interests of Certain
Persons in the Proposed Transaction" below.

   FOR THE REASONS DISCUSSED ABOVE, THE VPN BOARD OF DIRECTORS HAS UNANIMOUSLY
APPROVED THE ASSET ACQUISITION AGREEMENT AND THE PROPOSED TRANSACTION, AND IT
UNANIMOUSLY RECOMMENDS THAT VPN SHAREHOLDERS VOTE FOR APPROVAL OF THE PROPOSED
TRANSACTION.

   In considering the recommendation of VPN's board of directors with respect
to the proposed transaction, you should be aware that certain directors and
officers of VPN may have certain interests in the proposed transaction that are
different from, or are in addition to, the interests of VPN shareholders
generally. Please see the section entitled "--Interests of Certain Persons in
the Proposed Transaction" on page 24 of this proxy statement/prospectus.

UnitedHealth Group's Reasons for the Proposed Transaction

   As described above under "--Background of the Proposed Transaction," VPN had
the right to "put" its shares of UHC Virginia stock to Purchaser for $20
million in cash or UnitedHealth Group common stock, at VPN's option, if the
right was exercised on or before December 31, 2000. During the fourth quarter
of 2000, representatives of VPN indicated to UnitedHealth Group that VPN
intended to exercise this right. In order to provide for the exercise of this
put right and to resolve the cost-over-capitation issue between the parties,
UnitedHealth Group and Purchaser negotiated and entered into the asset
acquisition agreement with VPN.

Completion of the Proposed Transaction

   The sale of UHC Virginia common stock by VPN to Purchaser will be completed
when all of the conditions to closing set forth in the asset acquisition
agreement have been satisfied or waived, including the approval of the proposed
transaction by VPN shareholders. We are working to complete the proposed
transactions as quickly as possible. Because the closing is subject to
governmental approvals, however, we cannot predict the exact timing of the
closing.

                                       23
<PAGE>

Operation of UHC Virginia Following the Proposed Transaction

   After the sale of UHC Virginia common stock by VPN to Purchaser is
completed, UHC Virginia will be a wholly owned indirect subsidiary of
UnitedHealth Group. As such, UnitedHealth Group will have the ability to elect
all of UHC Virginia's directors and officers and to operate UHC Virginia in
such manner as it deems to be in UnitedHealth Group's own best interests, as
opposed to the current structure where UnitedHealth Group controls a majority
of shares.

Dissolution of VPN Following the Proposed Transaction

   The asset acquisition agreement provides that VPN shall dissolve and
terminate its corporate existence promptly after the closing of the transaction
contemplated thereby, and in any event not more than one year after the
closing. At its meeting on August 8, 1999, the VPN Board of Directors adopted a
Plan of Complete Liquidation and Distribution for VPN (the "Plan of
Liquidation"). VPN shareholders approved the Plan of Liquidation on October 6,
1999. It is the intention of the VPN Board of Directors that VPN will be
dissolved and terminated as described below and in accordance with the Plan of
Liquidation.

   In connection with the Plan of Liquidation, VPN will collect its assets, pay
all fixed and known liabilities, and make provision for unascertained or
contingent liabilities, all in accordance with applicable law and in reliance
on experts and consultants as appropriate and necessary. VPN's Board will use
its good faith business judgment to determine the propriety of making a final
reserve for contingent, unascertained, or unliquidated claims, and may
establish a liquidating trust to hold assets for the purpose or satisfying any
such claims for a period of time. VPN will then make a final distribution of
its remaining assets (less the potential reserve described above to meet claims
of creditors, if determined appropriate) on a pro rata basis to and among its
shareholders in complete cancellation of their shares. There can be no
assurance that unanticipated claims will not arise or that no claims will be
asserted in larger amounts than anticipated or reserved for. See "Certain
Federal Income Tax Considerations--Other Consequences--Forgiveness of Debt."
Although unlikely, the possibility exists that creditors could assert claims
against VPN's shareholders to satisfy such claims, but only to the extent of
the value of consideration received by such shareholders. See "Risk Factors--
Risks Related to the Proposed Transaction--Subsequent Liabilities."

   Finally, after completion of the steps outlined above but in no event more
than one year after closing the transaction contemplated herein, the VPN Board
will cause VPN to file Articles of Termination with the State Corporation
Commission of the Commonwealth of Virginia to terminate the corporate existence
of VPN.

Interests of Certain Persons in the Proposed Transaction

   No person that is or has been at any time an executive officer or director
of VPN since the beginning of VPN's last fiscal year has any interest in the
proposed transaction that is different from or in addition to his interest as a
VPN shareholder generally, except that VPN will pay to C. Gregory Lockhart,
M.D. and K. Marshall Cook those sums contractually required to terminate their
existing employment agreements with VPN. Dr. Lockhart is President, Chief
Executive Officer, Chairman of the Board of Directors and a director of VPN,
and Mr. Cook is Secretary and General Counsel of VPN. When the corporate
existence of VPN is terminated as required by the asset acquisition agreement,
Dr. Lockhart and Mr. Cook each will be entitled to receive a lump sum payment
equal to the amount of salary payable through the end of the stated terms of
their respective employment agreements with VPN. Both employment agreements
have a stated term ending December 31, 2002. Dr. Lockhart's provides for an
annual salary of $100,000, and Mr. Cook's provides for an annual salary of
$150,000.

VPN Common Stock Ownership

   No shareholder owns beneficially more than 5% of the outstanding shares of
VPN common stock as of January 12, 2001.

Regulatory Matters

   The closing of the purchase of UHC Virginia common stock by UnitedHealth
Group from VPN is conditioned upon the approval of the purchase by the Virginia
Bureau of Insurance. Neither VPN nor UnitedHealth Group is aware of any other
material governmental or regulatory approvals required for completion of the
transaction contemplated by the asset acquisition agreement.

Certain Federal Income Tax Considerations

   The following is a summary of the general federal income tax consequences to
VPN and its shareholders from the proposed transaction, which has been
structured to qualify as a tax-free "C reorganization" under existing
provisions of the Internal Revenue Code of 1986, as amended (Code) and U.S.
Treasury Regulations promulgated thereunder (Regulations). Consequently,
neither VPN nor its shareholders should recognize gain from the receipt of
UnitedHealth Group stock. While VPN and the VPN shareholders may recognize gain
to the extent that VPN sells assets to satisfy contingent liabilities and/or
the VPN shareholders receive cash in

                                       25
<PAGE>

liquidation of their VPN interests, such a sale and/or such a receipt of cash,
if any, are expected to involve relatively minor amounts that would not alter
the substantially tax-free nature of the proposed transaction.

 C Reorganization Requirements and Consequences.

   Generally. A tax-free C reorganization includes a transaction in which a
corporation (1) transfers substantially all of its assets to another
corporation solely in exchange for voting stock in a controlling parent of such
other corporation, and (2) distributes such voting stock to its own
shareholders in liquidation of their interests. In the proposed transaction,
VPN will (1) transfer its interest in UHC Virginia to Purchaser in exchange for
voting stock in UnitedHealth Group, which is a controlling parent of Purchaser
and (2) distribute such voting stock in UnitedHealth Group to VPN shareholders
in liquidation of their VPN interests.

   Substantially All of VPN's Assets. In order for the proposed transaction to
qualify as a C reorganization, the assets that VPN transfers to Purchaser must
constitute substantially all of VPN's assets. The precise quantity of assets
that must be transferred in order to meet the "substantially all" requirement
is not specified in the Code or the Regulations, and courts have reached
different conclusions on the matter. According to Revenue Procedure 77-37
(1977-2 C.B. 568), which sets forth the requirements established by the
Internal Revenue Service (IRS) for obtaining an advance ruling, the
"substantially all" requirement will be met if VPN transfers to Purchaser at
least 70 percent in value of its total gross assets and 90 percent in value of
its total net assets. The assets that VPN will transfer to Purchaser have a
value of approximately $20,300,000, its other assets (principally cash) have a
value of approximately $1,000,000 and thus its gross assets total $21,300,000.
VPN's liabilities consist of (a) approximately $900,000 in employment-related
contract obligations and transaction costs and (b) indebtedness to Purchaser,
the amount of which is in dispute but which is assumed for purposes of this
discussion to be approximately $2.3 million. Thus, VPN's net assets will be
approximately $18.1 million (that is $21,300,000 of gross assets minus
liabilities of approximately $3,200,000). Accordingly, VPN will transfer to
Purchaser approximately 95% of its gross assets and (even if the maximum
possible amount of the disputed liability is assumed) approximately 100% of its
net assets. Thus, VPN should satisfy the requirement set forth in Revenue
Procedure 77-37 for an advance ruling that it would be deemed to transfer
substantially all of its assets to Purchaser.

   Voting Stock in UnitedHealth Group. In order for the proposed transaction to
qualify as a C reorganization, the principal consideration that VPN receives in
exchange for the transfer of its assets to Purchaser must consist of voting
stock in UnitedHealth Group. In Section 368(a)(1)(C), the Code provides that
for purposes of this requirement, any indebtedness of VPN that is assumed by
Purchaser will be ignored in determining the consideration that VPN has
received. Because VPN will receive no actual cash or other property in the
transaction except UnitedHealth Group voting stock and because the resolution
and termination of VPN's indebtedness to Purchaser should not be considered
other consideration for purposes of this test (for the reasons stated herein),
VPN should meet the requirement that it receive principally voting stock in
UnitedHealth Group in exchange for its assets.

   Boot and Debt Resolution. Section 361(b) of the Code provides that under
certain circumstances VPN must recognize gain in an otherwise tax-free C
reorganization to the extent that (in addition to UnitedHealth Group voting
stock) it receives cash or other property (boot) in the transaction. However,
the Code also provides that for purposes of this rule, an assumption by
Purchaser of VPN's indebtedness will not constitute boot and thus should not
cause VPN to recognize gain.

   As described above, VPN's indebtedness to Purchaser will be "resolved and
terminated" in the proposed transaction. (The amount of such debt is in dispute
but for purposes of this discussion is assumed to equal approximately
$2,300,000.) This resolution will not be accomplished by a cash payment from
VPN to Purchaser but instead will be effected through the mechanism of reducing
the amount of UnitedHealth Group stock that VPN receives in the transaction
from that amount of UnitedHealth Group stock with a value of $20,300,000 (which
VPN is entitled to receive under its put right) to that amount of UnitedHealth
Group stock with a value of $17,948,278.04 (that is, approximately $2,300,000
less in value than VPN would be entitled to receive in the absence of such
arrangement with respect to the debt).

                                       26
<PAGE>

   In Revenue Ruling 72-264 (1972-2 C.B. 568), a corporation that was the
holder of a promissory note acquired all of the note maker's assets and
liabilities in a merger that qualified as a tax-free A reorganization. The IRS
ruled that acquisition of the debt that was evidenced by the note would be
considered an assumption of such debt by the acquiring corporation
notwithstanding that the acquiring corporation also was the creditor and that
the debt would be extinguished rather than paid off. Consequently, the debtor
corporation was not considered to have received taxable boot. Similarly, in a
1962 case where an individual transferred to his corporation all of his sole
proprietorship assets and liabilities, including a debt owed to such
corporation, the Tax Court held that the transfer of such debt would be
considered an assumption of the debt by the acquiring corporation as though the
acquiring corporation also was the creditor. As a result, the individual was
not required to recognize gain under a debt assumption rule similar to the rule
described above for a C reorganization.

   Based on Revenue Ruling 72-264 and the case described above, the resolution
and termination of VPN's indebtedness to Purchaser should be considered an
assumption of such debt by Purchaser. Consequently, VPN should not be
considered to have received boot and thus should not be required to recognize
gain from the resolution and termination of its indebtedness to Purchaser.

   Liquidation of VPN. In order for the proposed transaction to qualify as a C
reorganization, VPN must distribute all of its UnitedHealth Group stock and
other assets (net of amounts used to satisfy its liabilities) to its
shareholders and cease its business after the closing of the proposed
transaction. The asset acquisition agreement requires VPN to terminate its
legal existence within one year after the closing of the proposed transaction.
Based on the requirements of the asset acquisition agreement and the
resolutions of VPN's Board of Directors, it is assumed for purposes of this
discussion that VPN will satisfy this requirement.

   Conclusion. Based on the foregoing, the proposed transaction should qualify
as a tax-free C reorganization under the Code and VPN should not be considered
to receive any taxable boot in the transaction. As a result, VPN should not
recognize gain from a transfer of its assets to Purchaser in exchange for
UnitedHealth Group stock or from a transfer of UnitedHealth Group stock to the
VPN shareholders. In addition, the VPN shareholders should not recognize gain
from the receipt of UnitedHealth Group stock in liquidation of their interests
in VPN. VPN's tax basis in the UnitedHealth Group stock that it receives in the
proposed transaction will equal VPN's tax basis in the assets that it transfers
to Purchaser, reduced by the amount of VPN's indebtedness that Purchaser
assumes, or is deemed to assume, in the transaction. VPN's holding period for
such stock will include its holding period for the assets that it transfers to
Purchaser. The VPN shareholders' tax basis in the UnitedHealth Group stock that
they receive in the proposed transaction will equal their tax basis in their
VPN stock immediately prior to their receipt of such UnitedHealth Group stock,
and their holding period for such stock will include the holding period of
their stock in VPN. As a result, any gain or loss that a VPN shareholder
recognizes from a disposition of his UnitedHealth Group stock will constitute
long term capital gain or loss, as the case may be, if the shareholder's
combined holding period for VPN and UnitedHealth Group stock exceeds twelve
months.

 Other Consequences.

   Cash for Fractional Shares. In addition to voting stock, VPN will receive
cash in lieu of fractional shares from UnitedHealth Group. Such cash is not
separately negotiated consideration but represents an automatic rounding off
mechanism that is designed to avoid the inconvenience of fractional shares. In
this circumstance, cash received by VPN in lieu of fractional shares will not
be considered boot and thus VPN will not recognize gain from its receipt. When
VPN distributes such cash to its shareholders, the distribution will be
considered a payment to the shareholders in redemption of their fractional
shares, and will be subject to tax as capital gain under Revenue Ruling 66-365.

   Forgiveness of Debt. VPN would recognize income if its debt to Purchaser is
deemed to be forgiven rather than assumed. VPN has been advised by counsel and
its accountants that, although the matter is not free from doubt, it is more
likely than not that the resolution of the liability will be treated as a tax-
free debt assumption rather than a taxable debt forgiveness.

   The foregoing discussion addresses only the general federal income tax
consequences of the proposed transaction. It does not address any state or
local income tax consequences from the transaction. The actual tax consequences
may vary from shareholder to shareholder depending on each shareholder's
particular tax situation and accordingly each shareholder should consult his or
her own tax advisor about the effect of such consequences on his or her own
situation.

   The foregoing discussion and conclusions are based on the Code, Regulations,
IRS administrative pronouncement (such as revenue rulings) as currently in
effect and on case law as of the date of this prospectus. Future changes in the
law, any of which could have a retroactive affect, could alter the conclusions
contained herein.

   Hirschler, Fleischer, Weinberg, Cox & Allen, as counsel to VPN, will deliver
an opinion at closing that the federal income tax discussion herein fully,
fairly and accurately addresses the material federal income tax issues
associated with the proposed transaction and correctly and completely describes
current federal income tax law applicable to the issues discussed herein.
Subject to the limitations and assumptions contained herein, counsel's opinion
adopts all of the conclusions reached in this proxy statement/prospectus
regarding the tax consequences to VPN and its shareholders from the proposed
transaction. An opinion of counsel, however, is not binding on the IRS, and the
IRS could challenge one or more positions taken in reliance on conclusions
herein. No assurance can be given that the IRS will not challenge such
positions.

No Dissenters' Rights

   VPN shareholders will not have dissenters' rights of appraisal under the
Virginia Stock Corporation Act as a result of the transaction to be considered
at the special meeting.

Restrictions on Sale of Shares by Affiliates of VPN and UnitedHealth Group

   The shares of UnitedHealth Group common stock to be received by VPN's
shareholders pursuant to the asset acquisition agreement will be freely
transferable, except for shares of UnitedHealth Group common stock issued to
any person who is deemed to be an affiliate of either VPN or UnitedHealth Group
at the time of the special meeting. Persons who may be deemed to be affiliates
include individuals or entities that control, are controlled by, or are under
common control of either of VPN or UnitedHealth Group and may include the
executive officers and directors, as well as the principal shareholders, of
both companies. Affiliates may not sell their shares of UnitedHealth Group
common stock acquired in connection with the merger except in accordance with
Rule 145 under the Securities Act.

   The asset acquisition agreement requires VPN to deliver a written agreement
from each of its affiliates to the effect that such person will not offer or
sell or otherwise dispose of any of the shares of UnitedHealth Group common
stock issued to such person pursuant to the asset acquisition agreement except
in compliance with the Securities Act and the rules and regulations promulgated
by the Securities and Exchange Commission thereunder. This proxy
statement/prospectus may not be used in connection with the resale of shares of
UnitedHealth Group common stock received by affiliates of VPN.

Stock Market Listing

   An application will be filed for listing the shares of UnitedHealth Group
common stock to be issued pursuant to the asset acquisition agreement on the

granted under the Director Plan is the closing sale price of UnitedHealth Group
common stock on the date the option is granted. In 2000, each non-employee

(1) All options granted in 2000 expire ten years following the date of grant,
    subject to earlier termination upon certain events related to termination
    of employment. Options not yet exercisable generally become exercisable
    upon a change in control of UnitedHealth Group. A change in control as
    defined in UnitedHealth Group's Amended and Restated 1991 Stock and
    Incentive Plan occurs upon the sale of all or substantially all of the
    assets of UnitedHealth Group or any merger, reorganization or exchange or
    tender offer that will result in a change in the power to elect 50% or more
    of UnitedHealth Group's Board of Directors. The exercise price may be paid
    in cash, in shares of stock or pursuant to a cashless exercise procedure
    under which the optionee instructs a brokerage firm to sell the purchased
    shares and remit to UnitedHealth Group out of the proceeds an amount equal
    to the exercise price plus all applicable withholding taxes.

(2) The "potential realizable value" shown is the potential gain on the last
    day the option remains exercisable. This value will be achieved only if the
    options have been held for the full ten years and the stock price has
    appreciated at the assumed rate. Potential realizable value is listed for
    illustration only. The values disclosed are not intended to be, and should
    not be interpreted as, representations or projections of future value of
    UnitedHealth Group common stock or of the stock price.

(3) Options become exercisable at the rate of 25% per year over a period of
    four years on the first day of each year, beginning on January 1, 2001.

(4) Options become exerciseable at the rate of 25% per year over a period of
    four years on the eighth day of March of each year, beginning on March 8,
    2001.

(5) Options become exerciseable at the rate of 33.3% per year over a period of
    three years, subject to certain conditions.

(6) Options become exercisable at the rate of 25% per year over a period of
    four years on the twenty-sixth day of July of each year, beginning on July
    26, 2001.

(7) Options become exercisable at the rate of 25% per year over a period of
    four years on the twenty-sixth day of July of each year, beginning July 26,
    2001, subject to certain early vesting provisions.

Executive Employment Agreements

   UnitedHealth Group has entered into an employment agreement with each of the
executive officers named in the Summary Compensation Table.

                                       35
<PAGE>

   William W. McGuire, M.D. Dr. McGuire entered into a revised employment
agreement, effective October 13, 1999, to serve as Chief Executive Officer. The
initial term of this agreement is five years ending on October 13, 2004 and is
automatically extended for additional one-year periods on each anniversary of
the effective date unless either party delivers prior notice of intent not to
renew.

   Pursuant to the agreement, Dr. McGuire currently receives a base annual
salary of $1,700,000 which is subject to a minimum increase of $100,000 each
year. During each calendar year of the initial five-year term of the agreement,
Dr. McGuire receives a nonqualified stock option to purchase a minimum of
650,000 shares of UnitedHealth Group common stock. These stock options vest
over a period of four years at the rate of 25% per year, subject to additional
vesting provisions if specified future events occur. Dr. McGuire is eligible to
participate in UnitedHealth Group's incentive bonus plan at prescribed levels
and in its other employee benefit programs. In addition, UnitedHealth Group
provides and pays for life and disability policies on Dr. McGuire that he owns.
The agreement provides Dr. McGuire with a supplemental retirement benefit equal
to a percentage of his cash compensation during the three calendar years
preceding his retirement.

   The employment agreement provides severance benefits if Dr. McGuire's
employment by UnitedHealth Group ends under certain circumstances. If his
employment is terminated by UnitedHealth Group without cause or by Dr. McGuire
for good reason as those terms are defined in the agreement, UnitedHealth Group
will pay Dr. McGuire his salary and bonus for the 36 months following the
termination of his employment. In addition, Dr. McGuire will continue to
receive credited service under his supplemental retirement benefits for the 36-
month period. Certain stock options and restricted stock awards granted to
Dr. McGuire will also vest and his stock options will remain exercisable for a
period of up to 72 months but not beyond the expiration date of the respective
option.

   If Dr. McGuire's employment is terminated because of his death or permanent
disability, UnitedHealth Group will pay his beneficiaries or him his salary and
bonus for a period of 24 months. In addition, he or his beneficiaries will
receive the proceeds from his disability or life insurance policies, and
certain of his stock options will vest immediately and remain exercisable for
up to 36 months following his death or permanent disability but not beyond the
expiration date of the respective option.

   If Dr. McGuire voluntarily terminates his employment without good reason,
UnitedHealth Group will pay his beneficiaries or him his salary and bonus for a
period of 24 months. Any vested stock options at the time of the termination of
his employment will remain exercisable for up to 36 months following
termination of his employment but not beyond the expiration date of the
respective option. In addition, in the event of any termination of Dr.
McGuire's employment other than a termination for cause, UnitedHealth Group
will continue to provide health coverage for Dr. McGuire and his spouse for the
remainder of their lives and his children until age 25.

   Pursuant to the employment agreement, Dr. McGuire is subject to provisions
prohibiting his solicitation of UnitedHealth Group employees and competition
with UnitedHealth Group during the term of the agreement, for the period of the
severance payments and one year thereafter. In addition, he is prohibited at
all times from disclosing confidential information related to UnitedHealth
Group.

   Stephen J. Hemsley. Mr. Hemsley entered into an employment agreement,
effective October 13, 1999, to serve as President. This agreement continues
until it is terminated in accordance with its terms as discussed below.

   During each calendar year of the agreement, Mr. Hemsley receives a
nonqualified stock option to purchase a minimum of 300,000 shares of
UnitedHealth Group common stock. These stock options vest over a period of four
years at the rate of 25% per year based on the achievement of performance goals
established at the time of grant or upon the ninth anniversary of the date of
grant, subject to additional vesting provisions if specified

                                       36

future events occur. Mr. Hemsley is eligible to participate in UnitedHealth
Group's incentive bonus plan at prescribed levels and in its other employee
benefit programs. In addition, UnitedHealth Group provides and pays for life
and disability policies on Mr. Hemsley that he owns. Pursuant to the terms of
the agreement, UnitedHealth Group is in the process of establishing a
supplemental retirement benefit plan for Mr. Hemsley that will be reasonable
and customary for executives of a similar position in comparably sized
companies.

   The employment agreement provides severance benefits if Mr. Hemsley's
employment by UnitedHealth Group ends under certain circumstances. If his
employment is terminated by UnitedHealth Group without cause or by Mr. Hemsley
for good reason other than in connection with a change in control as those
terms are defined in the agreement, UnitedHealth Group will pay Mr. Hemsley two
times his annual salary and bonus over the 12 months following the termination
of his employment. If such termination is in connection with a change in
control, Mr. Hemsley will receive three times his annual salary and bonus over
the 12 months following the termination of his employment. If the termination
is in connection with a change in control, any stock options or restricted
stock awards granted to Mr. Hemsley will also vest and the stock options will
remain exercisable for a period of 36 months but not longer than the expiration
date under the respective option. If the termination is not in connection with
a change in control, the Compensation and Human Resources Committee will give
consideration to the vesting of any unvested options and the period that the
vested options remain exercisable after termination of Mr. Hemsley's
employment.

   If Mr. Hemsley's employment is terminated because of his death or permanent
disability, UnitedHealth Group will pay his beneficiaries or him his salary and
bonus for a period of 12 months. In addition, he or his beneficiaries will
receive the proceeds from his disability or life insurance policies, and his
stock options will vest immediately and remain exercisable for up to 36 months
following his death or permanent disability but not beyond the expiration date
of the respective option. In addition, in the event of any termination of Mr.
Hemsley's employment other than a termination for cause, UnitedHealth Group
will continue to provide health coverage for Mr. Hemsley and his spouse until
age 65 and his children until age 25.

   Pursuant to the employment agreement, Mr. Hemsley is subject to provisions
prohibiting his solicitation of UnitedHealth Group employees during the term of
the agreement, for the period of the severance payments and for one year
thereafter. Mr. Hemsley is also prevented from competing with UnitedHealth
Group during the term of his employment and the period that severance payments
are made to him under the employment agreement. In addition, he is prohibited
at all times from disclosing confidential information related to UnitedHealth
Group.

   Jeannine M. Rivet. Ms. Rivet entered into an employment agreement, effective
October 16, 1998, to serve in an executive position. This agreement remains in
effect until it is terminated by either party under certain circumstances.
Under this agreement, Ms. Rivet is eligible to participate in UnitedHealth
Group's incentive bonus and stock plans and its other employee benefit plans.

   R. Channing Wheeler. Mr. Wheeler entered into an employment agreement,
effective June 9, 1998, to serve in an executive position. The initial term of
this agreement is three years; after the initial term, this agreement
automatically renews for additional one year terms unless either party provides
prior notice of intent not to renew. Under this agreement, Mr. Wheeler is
eligible to participate in UnitedHealth Group's incentive bonus and stock plans
and its other employee benefit plans.

   Arnold H. Kaplan. Mr. Kaplan entered into an employment agreement, effective
May 19, 1998, to serve as Chief Financial Officer of UnitedHealth Group. This
agreement remains in effect until it is terminated by either party under
certain circumstances. Under this agreement, Mr. Kaplan is eligible to
participate in UnitedHealth Group's incentive bonus and stock plans and its
other employee benefit plans. Mr. Kaplan retired as Chief Financial Officer
effective as of January 2, 2001.

   Pursuant to their agreements, each of Ms. Rivet and Mr. Wheeler is entitled
to receive severance compensation for a 12-month period equal to the
executive's base salary and bonus (as determined by his or

                                       37
<PAGE>

her agreement) if the executive's employment is terminated by UnitedHealth
Group without cause or if a change in employment occurs (as defined in his or
her agreement). This severance compensation is greater if these events occur
within two years following a change in control (as defined in his or her
agreement). During the term of these agreements and during certain periods of
time following termination of these agreements, each executive is subject to
non-solicitation and non-competition provisions.

Severance Arrangements and Change-in-Control Provisions

   According to UnitedHealth Group's Severance Pay Plan, which applies to all
regular company employees, certain of the executive officers may be eligible to
receive severance pay following their termination in certain events. However,
any payments an executive officer receives in connection with a change in
control (as defined in and pursuant to an employment agreement with
UnitedHealth Group) will replace and be in lieu of payment and/or benefits
under any company severance program, including UnitedHealth Group's Severance
Pay Plan. Under UnitedHealth Group's Severance Pay Plan, the amount of
severance pay following termination depends upon the executive officer's length
of service, grade level within UnitedHealth Group, and the execution of a
company-approved release.

   In the case of a change in control of UnitedHealth Group, certain of the
outstanding stock options granted under UnitedHealth Group's Amended and
Restated 1991 Stock and Incentive Plan will become exercisable in full. Change
in control is defined for this purpose as the sale of all or substantially all
of UnitedHealth Group's assets, or any merger, reorganization or exchange or
tender offer that will result in a change in the power to elect 50% or more of
the members of UnitedHealth Group's Board of Directors.

                        THE ASSET ACQUISITION AGREEMENT

   The following is a summary of certain aspects of the asset acquisition
agreement. This summary does not purport to be complete and is qualified in its
entirety by reference to the complete text of the asset acquisition agreement,
which is incorporated by reference and attached to this proxy
statement/prospectus as Annex A.

Purchase and Sale of UHC Virginia Shares; Purchase Price

   Pursuant to the asset acquisition agreement, VPN agrees to sell to
Purchaser, and Purchaser agrees to purchase from VPN, all of VPN's right, title
and interest in and to 1,237.25 shares of common stock of UHC Virginia. The
purchase price to be paid under the asset acquisition agreement for these
shares of UHC Virginia common stock consists of:

  .  that number of shares of UnitedHealth Group common stock determined by
     dividing $17,948,278.04 by the "Parent Average Price," as defined below,
     and

  .  the Purchaser's becoming responsible for the resolution of a contested
     liability represented by VPN's promissory note in the amount of
     $2,351,721.96 payable to Purchaser (including accrued interest thereon),
     and VPN's having no further liability on the note.

For purposes of the foregoing, the term "Parent Average Price" means the
average closing price per share of UnitedHealth Group common stock on the New
York Stock Exchange for the 30 consecutive trading days ending with and
including the third business day preceding the date upon which the purchase and
sale of UHC Virginia shares is completed.

   The nature of the contested liability represented by the promissory note
referred to above is described earlier in this proxy statement/prospectus under
the caption "The Proposed Transaction--Background of the Proposed Transaction."
Except with respect to this note, the agreement provides that VPN shall retain,
and neither Purchaser nor UnitedHealth Group shall assume, any liabilities,
obligations or undertakings of VPN of any nature whatsoever, whether accrued or
unaccrued, fixed or contingent, known or unknown, due or to become due, or
otherwise.

   The asset acquisition agreement provides that the sale of UHC Virginia
shares pursuant thereto will satisfy VPN's right to "put" such shares to
Purchaser under an existing shareholders agreement between them. See "The
Proposed Transaction--Background of the Proposed Transaction."

Distribution of UnitedHealth Group Shares to VPN Shareholders

   At the time the foregoing transaction is closed, the shares of UnitedHealth
Group common stock which are included in the purchase price, as described
above, will be distributed on a pro rata basis to the holders of VPN common
stock in the following manner:

   At least two business days prior to the closing date (but no sooner than one
business day after the special shareholders meeting), VPN will provide to
Purchaser a list of all of the shareholders of VPN as of the close of business
on the preceding business day (the "Cutoff Date") and of the number of shares
of VPN common stock owned by each such shareholder at the close of business on
the Cutoff Date. VPN will not issue or reacquire any shares of VPN common
stock, and will not permit any such shares to be transferred on its books,
after the Cutoff Date and on or before the closing date.

   Purchaser will deliver or cause to be delivered to each VPN shareholder
identified in the foregoing list that number of shares of UnitedHealth Group
common stock, registered in such shareholders' respective names, determined by
multiplying the total number of shares of UnitedHealth Group common stock
required to be paid to VPN for distribution to VPN shareholders by a fraction,
the numerator of which is the number of shares of VPN common stock held by such
shareholder as set forth in such list, and the denominator of which is the
total number of shares of VPN common stock set forth in such list.

                                       41
<PAGE>

   Notwithstanding the foregoing, no fraction of a share of UnitedHealth Group
common stock will be delivered to any holder of VPN common stock. In lieu
thereof, Purchaser will pay to each holder of VPN common stock who would
otherwise be entitled to a fraction of a share of UnitedHealth Group common
stock an amount of cash (rounded to the nearest whole cent) equal to the
product of such fraction, multiplied by the closing price for a share of
UnitedHealth Group common stock on the New York Stock Exchange on the last full
trading day prior to the closing date.

   The shares of UnitedHealth Group common stock to be delivered to VPN
shareholders may, at VPN's option, be delivered by mailing stock certificates
evidencing such shares to VPN shareholders at their addresses as they appear in
VPN's stock register, or they may be delivered in the form of uncertificated
shares issued in accordance with the provisions of Minnesota law and the direct
registration system maintained by the registrar and transfer agent for
UnitedHealth Group common stock.

Dissolution and Termination of VPN Following the Closing

   The asset acquisition agreement provides that VPN shall dissolve and
terminate its corporate existence promptly after the closing of the transaction
contemplated thereby, and in any event not more than one year after the
closing. For more information concerning this dissolution and termination, see
"The Proposed Transaction--Dissolution of VPN Following the Proposed
Transaction."

Treatment of VPN Stock Options

   Holders of outstanding options to purchase VPN common stock will not be
entitled to receive shares of UnitedHealth Group common stock in connection
with the transaction contemplated by the asset purchase agreement unless such
options are exercised before the close of business on the Cutoff Date.

   VPN, on the one hand, and UnitedHealth Group and Purchaser, on the other,

Termination of the Asset Acquisition Agreement

   The asset acquisition agreement can be terminated at any time before the
closing by the mutual consent of VPN and UnitedHealth Group, whether or not
the proposed transaction has been approved by VPN shareholders. It also can be

  .  the proposed transaction has not been completed on or before May 30,
     2001, without the fault of the terminating party;

  .  the required approval by VPN shareholders is not obtained, without the
     fault of the terminating party; or

   In addition, VPN can terminate the asset acquisition agreement at any time
before the closing if UnitedHealth Group or Purchaser has breached any of its

perform in any material respect any of its agreements in the agreement, and

notice thereof from VPN.

Fees and Expenses

   The asset acquisition agreement provides that whether or not the transaction
contemplated by it is completed, VPN, on the one hand, and UnitedHealth Group
and Purchaser, on the other, will bear their own expenses in connection with
the transaction, except under the following two circumstances:

  .  If VPN or UnitedHealth Group terminates the agreement because VPN
     shareholder approval was not obtained, or if UnitedHealth Group
     terminates the agreement because VPN breached its representations,
     warranties or agreements or VPN's board of directors withdrew or
     adversely modified its approval or recommendation, then VPN must
     reimburse UnitedHealth Group for its reasonable out-of-pocket expenses
     in connection with the proposed transaction; and

  .  If VPN terminates the agreement because UnitedHealth Group or Purchaser
     breached its representations, warranties or agreements, then
     UnitedHealth Group must reimburse VPN for its reasonable out-of-pocket
     expenses in connection with the proposed transaction.

       COMPARISON OF RIGHTS OF SHAREHOLDERS OF UNITEDHEALTH GROUP AND VPN

   Upon completion of the proposed transaction described in this proxy
statement/prospectus you will become a shareholder of UnitedHealth Group, and
upon the dissolution and termination of VPN called for by the asset acquisition
agreement you will cease to be a shareholder of VPN. The internal affairs of
VPN are governed by the Virginia Stock Corporation Act and VPN's restated
articles of incorporation and bylaws, while the internal affairs of
UnitedHealth Group are governed by the Minnesota Business Corporation Act and
UnitedHealth Group's restated articles of incorporation and bylaws. For this
reason, the proposed transaction and the dissolution and termination of VPN
will result in your having somewhat different rights as a shareholder of
UnitedHealth Group than you had as a shareholder of VPN. This section describes
the material differences between your rights as a shareholder of the two
companies.

   The foregoing discussion of certain similarities and material differences
between the rights of UnitedHealth Group and VPN shareholders under their
respective governing statutes, articles of incorporation and bylaws is only a
summary of certain provisions and does not purport to be a complete description
of such similarities and differences, and is qualified in its entirety by
reference to Minnesota law and Virginia law, the common law thereunder and the
full text of the articles of incorporation and bylaws of each of UnitedHealth
Group and VPN.

                                    EXPERTS

   The consolidated balance sheets as of December 31, 1999 and 1998, and the
consolidated statements of operations, shareholders' equity and cash flows for
each of the three years in the period ended December 31, 1999, of UnitedHealth
Group incorporated by reference in this proxy statement/prospectus have been
audited by Arthur Andersen LLP, independent public accountants, as indicated in
their reports with respect thereto, and are incorporated herein by reference in
reliance upon the authority of said firm as experts in giving said reports.

   With respect to the unaudited condensed interim financial information for
the quarters ended September 30, 2000 and 1999, June 30, 2000 and 1999, and
March 31, 2000 and 1999 of UnitedHealth Group incorporated by reference in this
proxy statement/prospectus, Arthur Andersen LLP has applied limited procedures
in accordance with professional standards for a review of that information.
However, their separate reports thereon state that they did not audit and they
do not express an opinion on that condensed interim financial information.
Accordingly, the degree of reliance on their reports on that information should
be restricted in light of the limited nature of the review procedures applied.
In addition, the accountants are not subject to the liability provisions of
Section 11 of the Securities Act of 1933 for their reports on the unaudited
condensed interim financial information because these reports are not "reports"
or "parts" of the prospectus or elsewhere in the registration statement
prepared or certified by the accountants within the meaning of Sections 7 and
11 of the Securities Act of 1933.

                          ASSET ACQUISITION AGREEMENT

   This Asset Acquisition Agreement (this "Agreement"), dated December 29,
2000, is made and entered into by and among UnitedHealth Group Incorporated, a
Minnesota corporation ("Parent"), United HealthCare Services, Inc., a Minnesota
corporation and a direct wholly owned subsidiary of Parent ("Purchaser"), and
Virginia's Physician Network, Inc., a Virginia corporation ("Seller").

   WHEREAS, UnitedHealthcare, Inc., a Delaware corporation and a direct wholly
owned subsidiary of Purchaser, owns approximately 51% of the issued and
outstanding shares of common stock of United HealthCare of Virginia, Inc., a
Virginia corporation ("UHC Virginia"), and Seller owns the remaining
approximately 49% of the issued and outstanding shares of common stock of UHC
Virginia; and

   WHEREAS, the shares of common stock of UHC Virginia owned by Seller comprise
substantially all of the assets of Seller; and

   WHEREAS, Purchaser wishes to purchase from Seller, and Seller wishes to sell
to Purchaser, the shares of common stock of UHC Virginia owned by Seller in
exchange for (i) shares of common stock of Parent which will be distributed to
the shareholders of Seller on a pro rata basis and (ii) the resolution by
Purchaser of certain monetary obligations owing from Seller to Purchaser; and

   WHEREAS, it is intended that the transactions contemplated by this Agreement
will qualify as a "reorganization" within Section 368(a)(1)(C) of the Internal
Revenue Code of 1986, as amended (the "Code").

   NOW, THEREFORE, in consideration of the representations, warranties,
covenants and agreements set forth in this Agreement, the parties hereto,
intending to be legally bound, agree as follows:

                                   ARTICLE I

                          PURCHASE AND SALE OF ASSETS

   1.1. Purchase and Sale. On the terms and subject to the conditions set forth
in this Agreement, Seller shall, at the Closing (as defined in Section 1.5
hereof), sell, transfer and assign to Purchaser, and Purchaser shall purchase
and acquire from Seller, all of Seller's right, title and interest in and to
1,237.25 shares of common stock, par value $$1.00 per share, of UHC Virginia
(the "Purchased Shares"). Purchaser shall not purchase or acquire any assets of
Seller other than the Purchased Shares.

   1.2. Satisfaction of Seller's Contractual Put Right. In satisfaction of
Seller's put right as set forth in the Intra-Party Agreements (as hereinafter
defined), the Purchaser shall pay to the Seller for the Purchased Shares that
number of shares of common stock, par value $0.01 per share, of Parent ("Parent
Common Stock") determined by dividing $17,948,278.04 by the "Parent Average
Price".

The term "Parent Average Price" means the average closing price per share of
Parent Common Stock on the New York Stock Exchange for the thirty consecutive
trading days ending with and including the third business day preceding the
Closing Date.

   1.3. Resolution of Other Contractual Obligations. Purchaser agrees to be
responsible for the ultimate negotiation and resolution of the contested
liability represented by the promissory note dated November 5, 1999, from
Seller to Purchaser in the amount of $2,351,721.96, including accrued and
unpaid interest thereon

                                      A-1
<PAGE>

(the "Promissory Note"), and Seller shall have no further liability on the
Promissory Note. Except as provided above, Seller shall retain, and neither
Purchaser nor Parent shall assume, and nothing contained in this Agreement
shall be construed as an assumption by Purchaser or Parent of, any liabilities,
obligations or undertakings of Seller of any nature whatsoever, whether accrued
or unaccrued, fixed or contingent, known or unknown, due or to become due, or
otherwise.

   1.4. Payment of Shares.

   (a) At least two business days prior to the Closing Date (but in no event
sooner than 1 business day after the Seller Shareholder Meeting as described in
Section 2.14), Seller shall provide to Purchaser a list (the "Seller
Shareholder List"), certified as true, correct and complete by an officer of
Seller, of all of the shareholders of Seller as of the close of business on the
preceding business day (the "Cutoff Date") and of the number of shares of
common stock, par value $0.01 per share, of Seller ("Seller Common Stock")
owned by each such shareholder at the close of business on the Cutoff Date.
Seller shall not issue or reacquire any shares of Seller Common Stock, and
shall not permit any shares of Seller Common Stock to be transferred on the
books of Seller, after the Cutoff Date and on or before the Closing Date.

   (b) Purchaser shall deliver or cause to be delivered to each shareholder of
Seller identified in the Seller Shareholder List that number of shares of
Parent Common Stock, registered in such shareholders' respective names,
determined by multiplying the total number of shares of Parent Common Stock
payable pursuant to Section 1.2 by a fraction, the numerator of which is the
number of shares of Seller Common Stock held by such shareholder as set forth
in the Seller Shareholder List, and the denominator of which is the total
number of shares of Seller Common Stock set forth in the Seller Shareholder
List. Notwithstanding the above, at Seller's election, which shall be
communicated to Purchaser no later than three (3) business days prior to the
filing of the Registration Statement, Seller may direct that a portion of the
Parent Common Stock be paid and delivered to, and titled in the name of,
Seller.

   (c) Notwithstanding (b) above, no fraction of a share of Parent Common Stock
will be delivered to any holder of Seller Common Stock. In lieu thereof,
Purchaser shall pay to each holder of shares of Seller Common Stock who would
otherwise be entitled to a fraction of a share of Parent Common Stock an amount
of cash (rounded to the nearest whole cent) equal to the product of (i) such
fraction, multiplied by (ii) the closing price for a share of Parent Common
Stock on the New York Stock Exchange on the last full trading day prior to the
Closing Date.

   (d) At Seller's sole discretion, the shares of Parent Common Stock to be
delivered pursuant to (b) above may be delivered by mailing stock certificates
evidencing such shares to Seller's shareholders at their addresses as they
appear in Seller's stock register, or they may be delivered in the form
uncertificated shares of Parent Common Stock issued in accordance with the
provisions of Section 302A.417, Subd. 7 of the Minnesota Business Corporation
Act and the direct registration system maintained by the registrar and transfer
agent for Parent Common Stock.. Seller's determination in this regard shall be
communicated to Purchaser along with the Seller Shareholder List.

   1.5. Seller Guaranty to Virginia Bureau of Insurance. As set forth in
Section VI.L. of the Second Amendment and Restatement of Shareholder Agreement
between Purchaser and Seller dated June 30, 2000, Purchaser and Parent will (i)
assume all of Seller's obligations pursuant to that certain guaranty dated June
18, 1997 made by Seller to the Virginia Bureau of Insurance, (ii) use its
reasonable best efforts to have Seller released from such guaranty, and (iii)
indemnify and hold harmless Seller from and against any and all costs, claims,
payments, damages, or expenses (including, without limitation, legal expenses)
incurred by Seller related to any attempted or actual enforcement of such
guaranty.

   1.6. The Closing. The closing of the transactions contemplated by this
Agreement (the "Closing") shall take place at the offices of Parent within two
business days after the date on which the last of the conditions set forth in
Article V shall have been satisfied or waived, or at such other place and on
such other date as are mutually agreed upon by Parent, Purchaser and Seller
(the "Closing Date").

                                      A-2
<PAGE>

   1.7 Actions by Seller After Closing. As soon as is practicable after the
Closing (and in any event not more than one year after the Closing Date),
Seller shall dissolve and terminate its corporate existence in accordance with
the provisions of its articles of incorporation, bylaws, and the Virginia Stock
Corporation Act (the "VSCA").

   1.8. Dissenting Shares. For purposes of this Agreement, the term "Dissenting
Shares" means any shares of Seller Common Stock issued and outstanding
immediately prior to the Closing Date with respect to which dissenters rights
apply under Section 13.1-730 of the VSCA which are held by a holder who has not
voted in favor of the transactions contemplated by this Agreement or consented
thereto in writing and who has properly delivered to Seller a notice of intent
to demand payment pursuant to Section 13.1-733 of the VSCA. Notwithstanding any
provision of this Agreement to the contrary, no holder of Dissenting Shares
shall be entitled to receive shares of Parent Common Stock pursuant to Section
1.4 unless and until such holder fails to perfect or effectively withdraws or
otherwise loses such holder's right to payment under the VSCA. Instead, with
respect to all such Dissenting Shares on the Closing Date, Purchaser shall
issue Parent Common Stock to Seller in the amount that would otherwise be
issuable to holders of Dissenting Shares, and Seller shall comply with the
dissenter's rights statutes under Virginia law. Seller shall give Purchaser
notice of any notices of intent to demand payment which are received by Seller
with respect to Dissenting Shares.

                                   ARTICLE II

                    REPRESENTATIONS AND WARRANTIES OF SELLER

   Seller represents and warrants to Purchaser and Parent that the statements
contained in this Article II are true and correct:

   2.1. Organization and Qualification. Seller is a corporation duly organized,
validly existing, and in good standing under the laws of the Commonwealth of
Virginia and has all requisite corporate power and authority to own, lease and
operate its properties and to carry on its business as now being conducted.
Seller is duly qualified and in good standing in each jurisdiction where the
character of its properties owned or leased or the nature of its activities
makes such qualification necessary. Seller is not in violation of any of the
provisions of its articles of incorporation, bylaws, or other applicable
governing document.

   2.2. No Subsidiaries. There is no corporation or other organization, whether
incorporated or unincorporated, of which Seller directly or indirectly owns or
controls at least a majority of the securities or other interests having by
their terms ordinary voting power to elect a majority of the board of directors
or others performing similar functions.

   2.3. Capitalization.

   (a) The authorized capital stock of Seller consists of 10,000,000 shares of
Seller Common Stock. As of the date hereof, 2,151,180 shares of Seller Common
Stock were issued and outstanding, and Seller held no shares of Seller Common
Stock in its treasury. Seller has no outstanding bonds, debentures, notes or
other securities or obligations the holders of which have the right to vote or
which are convertible into or exercisable for securities having the right to
vote on any matter on which any shareholder of Seller has a right to vote. All
issued and outstanding shares of Seller Common Stock are duly authorized,
validly issued, fully paid, nonassessable and free of preemptive rights. Except
for options to purchase an aggregate of 175,912 shares of Seller Common Stock
which are outstanding under Seller's Virginia's Physician Network, Inc. Stock
Option

                                      A-3
<PAGE>

Plan dated April 22, 1998, as amended, ("Seller's Option Plan"), there are no
outstanding options, warrants, convertible or exchangeable securities or other
rights which obligate Seller to issue, exchange, transfer or sell any shares of
capital stock of Seller or any other securities or obligations which are
convertible into, exercisable for or exchangeable for any shares of such
capital stock. Other than agreements with Purchaser, including the Shareholder
Agreement between Purchaser and Seller dated March 1, 1996, the First Amendment
to the Shareholder Agreement dated January 1, 1998, the Second Amendment and
Restatement of Shareholder Agreement dated June 30, 2000, and the Letter
Agreement between Purchaser and Seller dated December 29, 1999 (collectively,
the "Intra-Party Agreements"), there are no outstanding obligations of Seller
to repurchase, redeem or otherwise acquire any shares of capital stock of
Seller.

   (b) The Seller Shareholder List delivered by Seller to Purchaser pursuant to
Section 1.4(a) will be a true, correct and complete list of all of the
shareholders of Seller as of the Cutoff Date and of the number of shares of
Seller Common Stock owned by each such shareholder at the close of business, in
each case as reflected on the books of the Seller, on the Cutoff Date.

   2.4. Authority Relative to this Agreement. Seller has the requisite
corporate power and authority to execute and deliver, and perform its
obligations under, this Agreement and, subject to obtaining the necessary
approval of its shareholders as required by the VSCA and Seller's articles of
incorporation and bylaws, to consummate the transactions contemplated hereby.
The execution and delivery of this Agreement and the consummation of the
transactions contemplated hereby have been duly and validly authorized by the
board of directors of Seller and no other corporate proceedings on the part of
Seller are necessary to authorize this Agreement or to consummate the
transactions contemplated hereby (other than approval by Seller's shareholders
as required by the VSCA and Seller's articles of incorporation and bylaws).
This Agreement has been duly and validly executed and delivered by Seller and,
assuming the due authorization, execution and delivery hereof by Purchaser and
Parent, constitutes a valid and binding agreement of Seller, enforceable
against Seller in accordance with its terms, except to the extent that its
enforceability may be limited by applicable bankruptcy, insolvency,
reorganization, moratorium or other laws affecting the enforcement of creditors
rights generally or by general equitable principles.

   2.5. No Conflict; Required Filings and Consents

   (a) Assuming that all filings, notices, permits, authorizations, consents
and approvals or waivers thereof have been duly made or obtained as
contemplated by (b) and (c) below, neither the execution and delivery of this
Agreement by Seller nor the consummation of the transactions contemplated
hereby nor the compliance by Seller with any of the provisions hereof will (i)
violate, conflict with, or result in a breach of any provision of, or
constitute a default (or an event which, with notice or lapse of time or both,
would constitute a default) under, or result in the termination or suspension
of, or accelerate the performance required by, or result in a right of
termination or acceleration under, or result in the creation of any lien upon
any of the properties or assets of Seller under, any of the terms, conditions
or provisions of (x) its articles of incorporation, bylaws, or other applicable
governing document, (y) any note, bond, charge, lien, pledge, mortgage,
indenture or deed of trust to which Seller is a party or to which it or any of
its properties or assets may be subject, or (z) any license, lease, agreement
or other instrument or obligation to which Seller is a party or to which it or
any of its properties or assets may be subject, or (ii) violate any judgment,
ruling, order, writ, injunction, decree, statute, rule or regulation applicable
to Seller or any of its properties or assets.

   (b) No filing or registration with or notification to and no permit,
authorization, consent or approval of any court, commission, governmental body,
regulatory authority, agency or tribunal wherever located (collectively,
"Governmental Approvals") is required to be obtained, made or given by Seller
in connection with the execution and delivery of this Agreement or the
consummation by Seller of the transactions contemplated hereby exceptthe filing
of a Form D with the Virginia Bureau of Insurance with respect to the purchase
and sale of the Purchased Shares and the approval of such filing by the
Virginia Bureau of Insurance.


                                      A-4
<PAGE>

   (c) No consent, approval, waiver, or other action on the part of, and no
notice to, any non-governmental person or entity is required to be obtained,
made or given by Seller in connection with the execution and delivery of this
Agreement or the consummation by Seller of the transactions contemplated hereby
except for the approval of the sale of the Purchased Shares by Seller and the
dissolution of Seller by the holders of at least two-thirds of the outstanding
shares of Seller Common Stock pursuant to Sections 13.1-724 and 13.1-742 of the
VSCA.

   2.6. Securities Law Registrations and Required Filings on the Part of
Seller. To the best of Seller's knowledge after reasonable investigation and
due diligence, Seller is not and has not been required to register Seller
Common Stock under the Securities Act of 1933, as amended, and the rules and
regulations promulgated thereunder (the "Securities Act") or the Securities
Exchange Act of 1934, as amended, and the rules and regulations promulgated
thereunder (the "Exchange Act") or the securities or Blue Sky laws of any
state, except that Seller has registered by qualification under the Virginia
Securities Act and sold 2,040,755 shares of Seller common stock pursuant to
that certain Registration Statement of Seller dated March 25, 1996. To the best
of Seller's knowledge after reasonable investigation and due diligence, Seller
is not and has not been required to file any annual or quarterly reports, proxy
statements, or other documents with the Securities and Exchange Commission (the
"SEC") under the Exchange Act.

   2.7. Title to Purchased Shares, Etc.

   (a) Other than a Stock Pledge Agreement dated November 5, 1999 with Seller
as pledgor and Purchaser, as pledgee, to secure Seller's obligations under the
Note (the "Pledge Agreement"), Seller owns, beneficially and of record, all
right, title and interest in and to the Purchased Shares free and clear of any
security interests, claims, liens, pledges, options, encumbrances, charges,
agreements, voting trusts, proxies or other arrangements, restrictions or
limitations of any kind. On the Closing Date, the delivery by Seller of a stock
certificate or certificates evidencing the Purchased Shares in the manner set
forth in Section 5.2(f) hereof will transfer good and valid title to the
Purchased Shares to Purchaser, free and clear of any security interests,
claims, liens, pledges, options, encumbrances, charges, agreements, voting
trusts, proxies or other arrangements, restrictions or other legal or equitable
limitations of any kind.

   (b) The Purchased Shares constitute all of the shares of capital stock of
UHC Virginia which are owned beneficially or of record by Seller. Other than
pursuant to the Intra-Party Agreements, Seller has no rights to acquire any
shares of capital stock of UHC Virginia from UHC Virginia or any other person
or entity. The Purchased Shares constitute substantially all of the assets of
Seller within the meaning of Section 368(a)(1)(C) of the Code.

   2.8. Compliance with Law. To the best of Seller's knowledge, all activities
of Seller have been, and are currently being, conducted in compliance in all
material respects with all applicable United States federal, state, and local
laws, ordinances, regulations, interpretations, judgments, decrees,
injunctions, permits, licenses, certificates, governmental requirements, orders
and other similar items of any court or other governmental entity or any
nongovernmental self-regulatory agency.

   2.9. Litigation. There is no (a) claim, action, suit or proceeding pending
or, to Seller's knowledge, overtly threatened against or relating to Seller
before any court or other governmental entity, (b) alternative dispute
resolution proceeding pending or overtly threatened against Seller, or (c)
outstanding judgment, order, writ, injunction or decree, or application,
request or motion therefor, of any court or other governmental entity in a
proceeding to which Seller or any of its assets was or is a party, and Seller
is not in default with respect to any such judgment, order, writ, injunction or
decree.

   2.10. Taxes.

   (a) "Tax" or "Taxes" shall mean all United States federal, state,
provincial, local or foreign taxes and any other applicable duties, levies,
fees, charges and assessments that are in the nature of a tax, including

which have been filed but which were filed late Seller has prepared and timely

other material Tax returns and reports required to be filed (collectively
"Returns"), taking into account any extension of time to file granted to or
obtained on behalf of Seller;

     (ii) all Taxes of Seller shown on such Returns or all Taxes otherwise
  known by Seller to be due or payable (including the uncontested portion of
  any Taxes which are being contested) have been timely paid in full to the
  proper authorities, other than such Taxes as are being contested in good
  faith by appropriate proceedings or which are adequately reserved for in
  accordance with generally accepted accounting principles;

     (iii) all deficiencies resulting from Tax examinations of income, sales
  and franchise and all other material Returns filed by Seller in any
  jurisdiction in which such Returns are required to be so filed have either
  been paid or are being contested in good faith by appropriate proceedings;

     (iv) no deficiency has been asserted or assessed against Seller which
  has not been satisfied or otherwise resolved, and no examination of Seller

      issue, exchange, transfer or sell any shares of capital stock of
      Seller or any other securities or obligations which are convertible
      into, exercisable for or exchangeable for any shares of such capital
      stockTo the knowledge of such counsel, other than the Intra-Party

      to authorize this Agreement or to consummate the transactions
      contemplated hereby. This Agreement has been duly and validly
      executed and delivered by Seller and, assuming the due
      authorization, execution and delivery hereof by Purchaser and
      Parent, constitutes a valid and binding agreement of Seller,

      the extent that its enforceability may be limited by applicable
      bankruptcy, insolvency, reorganization, moratorium or other laws
      affecting the enforcement of creditors rights generally or by
      general equitable principles.

         (iv) Neither the execution and delivery of this Agreement by
      Seller nor the consummation of the transactions contemplated hereby
      nor the compliance by Seller with any of the provisions hereof will
      (i) violate, conflict with, or result in a breach of any provision

      of time or both, would constitute a default) under, or result in the
      termination or suspension of, or accelerate the performance required
      by, or result in a right of termination or acceleration under, or
      result in the creation of any lien upon any of the properties or
      assets of Seller under, any of the terms, conditions or provisions

      subject, or (ii) violate any judgment, ruling, order, writ,
      injunction, or decree known to such counsel, or any statute, rule or
      regulation, applicable to Seller or any of its properties or assets.

                            SELLER AFFILIATE LETTER

         , 2001

UnitedHealth Group Incorporated
United HealthGroup Center
9900 Bren Road East
Minnetonka, Minnesota 55343

Ladies and Gentlemen:

   Reference is made to the terms of that Asset Acquisition Agreement dated
December     , 2000 (the "Agreement"), by and among UnitedHealth Group
Incorporated, a Minnesota corporation ("Parent"), United HealthCare Services,
Inc., a Minnesota corporation and a direct wholly owned subsidiary of Parent
("Purchaser"), and Virginia's Physician Network, Inc., a Virginia corporation
("Seller"). I understand that as a result of the transactions contemplated by
the Agreement, I may receive shares of common stock, par value $0.01 per share,
of Parent ("Parent Common Stock"), in proportion to my ownership of shares of
common stock, par value $0.01 per share, of Seller ("Seller Common Stock"). I
have been advised that as of the date of this letter I may be deemed to be an
"affiliate" of Seller, as that term is defined by the Securities and Exchange
Commission (the "SEC") for purposes of Rule 145 promulgated under the
Securities Act of 1933, as amended (the "Securities Act")

   In connection with the foregoing, I hereby represent and warrant to, and
covenant with, Parent that:

   1. I am the record and/or beneficial owner of an aggregate of
shares of Seller Common Stock (the "Shares"). The Shares are not subject to any
claim, lien, pledge, charge, security interest or other encumbrance or to any
rights of first refusal of any kind. There are no options, warrants, calls,
rights, commitments or agreements of any character, written or oral, to which I
am a party or by which I am bound obligating me to issue, deliver, sell,
repurchase or redeem, or cause to be issued, delivered, sold, repurchased or
redeemed, any Shares or obligating me to grant or enter into any such option,
warrant, call, right, commitment or agreement. I have the sole right to
transfer such Shares. The Shares constitute all shares of Seller Common Stock
owned, beneficially or of record, by me. The Shares are not subject to
preemptive rights created by any agreement to which I am a party. All shares of
Seller Common Stock acquired by me subsequent to the date hereof shall be
subject to the provisions of this letter agreement as if held by me as of the
date hereof.

   2. I will not sell, transfer or otherwise dispose of any of the shares of
Parent Common Stock that I receive as a result of the transactions contemplated
by the Agreement in violation of the Securities Act or any rules or regulations
promulgated thereunder. As provided in the Agreement, Parent will use good
faith efforts to comply with Rule 144(c)(1) under the Securities Act so that
the resale provisions of Rule 145 are available to me.

   3. I understand that Parent will issue stop transfer instructions to its
transfer agent with respect to Parent Common Stock I receive as a result of the
transactions contemplated by the Agreement and that a restrictive legend will
be placed on any certificates for the Parent Common Stock issued to me, which
legend will be in substantially the following form:

     "The shares represented by this certificate were issued in a transaction
  to which Rule 145 promulgated under the Securities Act of 1933, as amended,
  applies and may not be sold or otherwise disposed of unless the proposed
  sale or disposition can be made in compliance with Rule 145. The shares
  represented by this certificate may be transferred only in accordance with
  the terms of a letter agreement dated          , 2001, between the holder
  and UnitedHealth Group Incorporated."

In connection with any sale or other transfer of Parent Common Stock so
acquired by me, the undersigned agrees to provide to Parent (i) satisfactory
written evidence that the shares have been sold in compliance with

                                      A-20
<PAGE>

Rule 145 (in which case, the substitute certificate will be issued in the name
of the transferee), or (ii) an opinion of counsel, in form and substance
reasonably satisfactory to Parent, to the effect that public sale of the shares
by the holder thereof is no longer subject to Rule 145.

   4. I understand that the representations, warranties and covenants by me set
forth herein will be relied upon by Parent, Seller and their respective
affiliates and counsel. I have carefully read this letter agreement and the
Agreement and have discussed their requirements and the limitations on my
ability to offer to sell, transfer or dispose of Parent Common Stock, to the
extent I felt necessary, with my counsel or counsel for Seller.

   Execution of this letter agreement shall not be considered an admission on
my part that I am an affiliate of Seller as described in the first paragraph of
this letter, or as a waiver of any rights I may have to object to any claim
that I am such an affiliate on or after the date of this letter. This letter
agreement shall terminate and be of no further force or effect if the Agreement
is terminated pursuant to the terms thereof.

                                          Sincerely,

                                          [Name of Affiliate]

Agreed and accepted this       day of            , 2001 by

ITEM 20. INDEMNIFICATION OF DIRECTORS AND OFFICERS.

   Minnesota Statutes Section 302A.521 provides that a corporation shall
indemnify any person made or threatened to be made a party to a proceeding by
reason of the former or present official capacity of such person against
judgments, penalties, fines (including, without limitation, excise taxes
assessed against such person with respect to any employee benefit plan),
settlements and reasonable expenses, including attorneys' fees and
disbursements, incurred by such person in connection with the proceeding, if,
with respect to the acts or omissions of such person complained of in the
proceeding, such person (1) has not been indemnified therefor by another
organization or employee benefit plan; (2) acted in good faith; (3) received no
improper personal benefit and Section 302A.255 (with respect to director
conflicts of interest), if applicable, has been satisfied; (4) in the case of a
criminal proceeding, had no reasonable cause to believe the conduct was
unlawful; and (5) reasonably believed that the conduct was in the best
interests of the corporation in the case of acts or omissions in such person's
official capacity for the corporation or reasonably believed that the conduct
was not opposed to the best interests of the corporation in the case of acts or
omissions in such person's official capacity for other affiliated
organizations. Article IX of the amended and restated bylaws of UnitedHealth
Group provides that UnitedHealth Group shall indemnify officers and directors
to the extent permitted by Section 302A.521 as now enacted or hereafter
amended.

   UnitedHealth Group also maintains an insurance policy or policies to assist
in funding indemnification of directors and officers for certain liabilities.

ITEM 22. UNDERTAKINGS.

   The undersigned Registrant hereby undertakes:

      (1) that, for purposes of determining any liability under the
  Securities Act, each filing of the Registrant's annual report pursuant to
  Section 13(a) or Section 15(d) of the Securities Exchange Act of 1934, as
  amended (the "Exchange Act") (and, where applicable, each filing of an
  employee benefit plan's annual report pursuant to Section 15(d) of the
  Exchange Act) that is incorporated by reference in this Registration
  Statement shall be deemed to be a new registration statement relating to
  the securities offered therein, and the offering of such securities at that
  time shall be deemed to be the initial bona fide offering thereof;

      (2) that, prior to any public reoffering of the securities registered
  hereunder through use of a prospectus which is a part of this Registration
  Statement, by any person or party who is deemed to be an underwriter within
  the meaning of Rule 145(c), such reoffering prospectus will contain the
  information called for by the applicable registration form with respect to
  reofferings by persons who may be deemed underwriters, in addition to the
  information called for by the other items of the applicable form;

                                      II-3
<PAGE>

      (3) that every prospectus (i) that is filed pursuant to paragraph (2)
  immediately preceding, or (ii) that purports to meet the requirements of
  Section 10(a)(3) of the Securities Act and is used in connection with an
  offering of securities subject to Rule 415, will be filed as a part of an
  amendment to this Registration Statement and will not be used until such
  amendment is effective, and that, for purposes of determining any liability
  under the Securities Act, each such post-effective amendment shall be
  deemed to be a new registration statement relating to the securities
  offered therein, and the offering of such securities at that time shall be
  deemed to be the initial bona fide offering thereof;

      (4) to respond to requests for information that is incorporated by
  reference into the prospectus pursuant to Item 4, 10(b), 11 or 13 of Form
  S-4, within one business day of receipt of such request, and to send the
  incorporated documents by first class mail or other equally prompt means.
  This includes information contained in documents filed subsequent to the
  effective date of this Registration Statement through the date of
  responding to the request;

      (5) to supply by means of a post-effective amendment all information
  concerning a transaction, and the company being acquired involved therein,
  that was not the subject of and included in this Registration Statement
  when it became effective; and

      (6) Insofar as indemnification for liabilities arising under the
  Securities Act may be permitted to directors, officers and controlling
  persons of the Registrant pursuant to the provisions described under Item
  20 above, or otherwise, the Registrant has been advised that in the opinion
  of the Securities and Exchange Commission such indemnification is against
  public policy as expressed in the Securities Act and is, therefore,
  unenforceable. In the event that a claim for indemnification against such
  liabilities (other than the payment by the Registrant of expenses incurred
  or paid by a director, officer or controlling person of the Registrant in
  the successful defense of any action, suit or proceeding) is asserted by
  such director, officer or controlling person in connection with the
  securities being registered, the Registrant will, unless in the opinion of
  its counsel the matter has been settled by controlling precedent, submit to
  a court of appropriate jurisdiction the question whether such
  indemnification by it is against public policy as expressed in the
  Securities Act and will be governed by the final adjudication of such
  issue.
